Offer by Banner Acquisition, Inc.
to Exchange Each Outstanding Share of Common Stock
of
Inamed Corporation
for
$84.00 in Cash
or
0.8498 of a Share of Common Stock of Allergan, Inc.
subject in each case, to the proration and election procedures
described in this prospectus and the related letter of election and transmittal
THE OFFER AND THE WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MONDAY, JANUARY 9, 2006, UNLESS EXTENDED. SHARES TENDERED PURSUANT TO THE OFFER MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION DATE.
Banner Acquisition, Inc. (“Offeror”), a newly formed, wholly owned subsidiary of Allergan, Inc. (“Allergan”), is offering to exchange for each outstanding share of common stock of Inamed Corporation (“Inamed”), par value $0.01 per share, including the associated preferred stock purchase rights (the “Inamed Shares”), validly tendered and not properly withdrawn in the offer, at the election of the holder of such Inamed Share:
  $84.00 in cash, without interest, or
 
 
  0.8498 of a share of Allergan common stock (including the associated preferred stock purchase rights),
subject in each case to the proration and election procedures described in this prospectus and the accompanying letter of election and transmittal (which together, as each may be amended, supplemented or otherwise modified from time to time, constitute the “Offer”). In the Offer, 45% of the aggregate Inamed Shares tendered will be exchanged for cash and 55% of the aggregate Inamed Shares tendered will be exchanged for shares of Allergan common stock. Therefore, elections will be subject to proration if holders of Inamed Shares, in the aggregate, elect to receive more than the maximum amount of consideration to be paid in the form of cash or Allergan common stock, as the case may be. See “The Offer— Elections and Proration” for a detailed description of the proration procedure. In addition, instead of receiving any fractional shares of Allergan common stock to which Inamed stockholders otherwise would be entitled, tendering Inamed stockholders will receive an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the exchange agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock issued pursuant to the Offer.
The purpose of the Offer is for Allergan to acquire control of, and ultimately the entire equity interest in, Inamed. The Offer is the first step in Allergan’s plan to acquire all of the outstanding Inamed Shares. Allergan intends promptly after completion of the Offer to seek to consummate a merger of Offeror with and into Inamed, with Inamed surviving the Merger (this merger is referred to herein as the “Inamed Merger”, and Inamed after the Inamed Merger is sometimes referred to as the “Surviving Corporation”). The purpose of the Inamed Merger is for Allergan to acquire all Inamed Shares not acquired in the Offer. After the Inamed Merger, the Surviving Corporation will be a wholly owned subsidiary of Allergan and the former Inamed stockholders will no longer have any ownership interest in the Surviving Corporation. As promptly as practicable following the Inamed Merger, Allergan will cause the Surviving Corporation to merge with and into a limited liability company wholly owned by Allergan, with the limited liability company surviving the merger (we refer to this second merger as the “Post-Closing Merger”).
On November 14, 2005, the last full trading day before the public announcement of Allergan’s proposal to acquire Inamed, the closing sales price of an Inamed Share was $74.44. The Offer had a value of $84.00 on November 15, 2005, the date the Offer was announced, which represented a premium of $9.56 per Inamed Share, or approximately 13%, over the value of an Inamed Share, immediately prior to the public announcement of the Offer. As of December 21, 2005, the most recent practicable date prior to the date of this prospectus, the Offer had a value of $87.95 per Inamed Share (assuming full proration), which represents a premium of $13.51 per Inamed Share, or approximately 18%, over the closing sales price of an Inamed Share immediately prior to the public announcement of the Offer. In addition, as of December 21, 2005, the value of the Offer represented a premium of $21.71 per Inamed Share, or approximately 33%, over the $66.24 closing sales price of an Inamed Share on March 18, 2005, the last full trading day prior to the March 21, 2005 public announcement of the proposed business combination of Inamed and Medicis Pharmaceutical Corporation, which subsequently was terminated on December 13, 2005. The market prices of shares of Allergan common stock and Inamed Shares will fluctuate prior to the expiration date of the Offer and thereafter, and may be higher or lower at the expiration date than the prices set forth above. As any premium represented by the Offer is based on fluctuating market prices, the premiums described above will similarly change.
Offeror’s obligation to exchange Inamed Shares for cash and shares of Allergan common stock in the Offer is subject to a number of conditions, which are more fully described in “The Offer— Conditions of the Offer.”
Allergan’s common stock is listed on the New York Stock Exchange under the symbol “AGN.” Inamed Shares trade on the NASDAQ National Market under the symbol “IMDC.”
For a discussion of certain factors that Inamed stockholders should consider in connection with the Offer, please carefully read “Risk Factors” beginning on page 11.

FORWARD-LOOKING STATEMENTS
      Statements made by Allergan and Offeror in this prospectus and in other reports and statements released by Allergan or Offeror that are not historical facts constitute “forward-looking statements.” These forward-looking statements are necessarily estimates reflecting the best judgment of senior management of Allergan and Offeror and include comments that express Allergan’s opinions about trends and factors that may impact its future operating results. The use of future tense and words such as “believe,” “anticipate,” “estimate,” “intend,” “could,” “plan,” “expect” and similar expressions are intended to identify forward-looking statements. Such statements rely on a number of assumptions concerning future events, many of which are outside of Allergan’s control, and involve risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. These risks and uncertainties include those described in “Risk Factors” beginning on Page 11 of this prospectus.
      Inamed stockholders are cautioned that, while forward-looking statements reflect the good faith belief and best judgment of Allergan and Offeror based upon current information, they are not guarantees of future performance. All forward-looking statements, made in or incorporated by reference into this prospectus or elsewhere, should be considered in context with the risk factors discussed or incorporated by reference into this prospectus and the various disclosures made by Allergan about its businesses, and by Inamed about its business, in their various public reports incorporated herein by reference.

SUMMARY
This section summarizes material information presented in greater detail elsewhere in this prospectus. However, this summary does not contain all of the information that may be important to Inamed stockholders. Important information is contained elsewhere in this prospectus and the other documents to which this prospectus refers, all of which should be carefully reviewed by Inamed stockholders. See “Where To Obtain More Information.”
As used in this prospectus, unless otherwise indicated or the context requires, “Allergan” refers to Allergan, Inc. and its consolidated subsidiaries, “Offeror” refers to Banner Acquisition, Inc., and “Inamed” refers to Inamed Corporation and its consolidated subsidiaries.
The Offer to Exchange (Page 59)
Under the terms of the Offer, each Inamed stockholder may elect to receive, for each Inamed Share validly tendered and not properly withdrawn, either:
$84.00 in cash, without interest; or
 
0.8498 of a share of newly issued Allergan common stock (including associated preferred stock purchase rights),
in each case, subject to the proration and election procedures described in this prospectus and the related letter of election and transmittal.
In the Offer, 45% of the aggregate Inamed Shares tendered will be exchanged for cash and 55% of the aggregate Inamed Shares tendered will be exchanged for shares of Allergan common stock. Therefore, elections will be subject to proration if tendering holders of Inamed Shares, in the aggregate, elect to receive more than the maximum amount of consideration to be paid in cash or Allergan common stock pursuant to the Offer. The ratio of 0.8498 of an Allergan share for each Inamed Share was determined by dividing $84.00 by the closing price of an Allergan share on the New York Stock Exchange on November 14, 2005, the last trading day before Allergan announced its proposal to acquire Inamed.
Potential Value of Offer Consideration
Based on the closing price of Allergan common stock on the New York Stock Exchange on December 21, 2005, the most recent practicable date prior to the date of this prospectus, 0.8498 of an Allergan share had a value of $91.19 per share. The value of 0.8498 of an Allergan share will fluctuate prior to the expiration date of the Offer as the market price of Allergan common stock changes. At Allergan share prices of $98.85 and above, the value of 0.8498 of an Allergan share will exceed the cash offer of $84.00 per Inamed Share, and at Allergan share prices below $98.85, the cash offer will exceed the value of 0.8498 of an Allergan share.

Table of Contents

Solely for purposes of illustration, the following table reflects the per share amount of cash and the market value of the Allergan common stock that an Inamed stockholder would receive for each Inamed Share tendered pursuant to the Offer if exactly 55% of the Inamed Shares tendered by the stockholder were exchanged for Allergan common stock and 45% of such shares were exchanged for cash. This would be the case, for example, if all tendering Inamed stockholders made the same election for either cash or Allergan shares. In that circumstance, each Inamed Share would be exchanged, on average, for $37.80 in cash (i.e. 45% of $84.00) and 0.46739 shares (i.e. 55% of 0.8498) of Allergan common stock. The table indicates the relative value, in that circumstance, of the two forms of consideration at different market values for the Allergan shares.
                             
Assumed           Implied Value
Market Price   Value of 0.46739 of   Cash Amount Paid   (per Inamed Share
(per Allergan Share)   an Allergan Share   (per Inamed Share)   exchanged)
             
$ 85.00     $ 39.73     $ 37.80     $ 77.53  
$ 90.00     $ 42.07     $ 37.80     $ 79.87  
$ 95.00     $ 44.40     $ 37.80     $ 82.20  
$ 100.00     $ 46.74     $ 37.80     $ 84.54  
$ 105.00     $ 49.08     $ 37.80     $ 86.88  
$ 110.00     $ 51.41     $ 37.80     $ 89.21  
$ 115.00     $ 53.75     $ 37.80     $ 91.55  
The market prices of Allergan common stock used in the above table, and the assumptions regarding the mix of cash and/or stock a hypothetical Inamed stockholder would receive are for purposes of illustration only. The price of Allergan common stock fluctuates and may be higher or lower than in these examples at the time the Offer is completed. In addition, due to the proration mechanisms in the Offer, the elections of other Inamed stockholders will impact whether a tendering Inamed stockholder receives the type of consideration elected, or is prorated so that a portion of such stockholder’s tendered shares are exchanged for another form of consideration.
Inamed stockholders should consider the potential effects of proration and should obtain current market quotations for shares of Allergan common stock and Inamed Shares before deciding whether to tender pursuant to the Offer and before electing the form of Offer consideration they wish to receive. The market price of shares of Allergan common stock will fluctuate prior to the expiration date of the Offer and thereafter, and may be different at the expiration date and at the time tendering Inamed stockholders receive cash or shares of Allergan common stock.
Proration Procedures
If Inamed stockholders elect to receive more than the aggregate amount of cash or shares of Allergan common stock offered, Allergan will prorate the total cash or stock, as the case may be, proportionally among the stockholders who elect that form of consideration. Inamed stockholders who do not make an election will be allocated whatever form of consideration is remaining (or a proportionate share of each form of consideration if neither is oversubscribed), after taking into account the preferences of the tendering stockholders who make elections. If neither form of consideration is oversubscribed, Inamed stockholders who do not make an election will receive cash and Allergan common stock in a proportion such that 45% of the aggregate Inamed Shares tendered in the Offer will be exchanged for cash and 55% of the aggregate Inamed Shares tendered in the Offer will be exchanged for shares of Allergan common stock. The procedures for prorating cash and common stock are described in “The Offer— Elections and Proration.”
Treatment of Fractional Shares
Inamed stockholders will not receive any fractional shares of Allergan common stock in the Offer. Instead of receiving any fractional shares of Allergan common stock to which Inamed stockholders otherwise would be entitled, tendering Inamed stockholders will receive an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the

exchange agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock issued pursuant to the Offer, as described in “The Offer— Cash Instead of Fractional Shares of Allergan Common Stock.”
The Inamed Merger (Page 73)
Allergan intends, promptly after the completion of the Offer, to seek to have Offeror merge into Inamed, with Inamed surviving the merger. After the Inamed Merger, Inamed will be a wholly owned subsidiary of Allergan and the former Inamed stockholders will not have any equity ownership interest in Inamed as the surviving corporation. In the Inamed Merger, each Inamed Share (except for Inamed Shares held in Inamed’s treasury and Inamed Shares beneficially owned directly or indirectly by Allergan or Offeror, including Inamed Shares acquired in the Offer) will be converted into the right to receive cash or shares of Allergan common stock, subject to appraisal rights under Delaware law, as more fully described under “The Offer— Purpose of the Offer; the Inamed Merger; Appraisal Rights.”
In the Inamed Merger, Inamed stockholders will have the opportunity to elect to receive for each Inamed Share cancelled in the Inamed Merger, $84.00 in cash or 0.8498 of a share of Allergan common stock. This is the same consideration as is available in the Offer, and such consideration will be subject to proration, such that in the aggregate 45% of the aggregate Inamed Shares cancelled in the Inamed Merger will be converted to cash and 55% of the aggregate Inamed Shares cancelled in the Inamed Merger will be converted into shares of Allergan common stock, subject to any adjustments necessary to preserve the status of the Offer, the Inamed Merger, and the Post-Closing Merger as a reorganization under Section 368(a) of the Internal Revenue Code.
The Post-Closing Merger (Page 74)
As soon as reasonably practicable after the Inamed Merger, Allergan intends to cause the Surviving Corporation to merge with and into a wholly owned limited liability company subsidiary of Allergan. Immediately before the Post-Closing Merger, Allergan will be the sole stockholder of the Surviving Corporation, and none of the former Inamed stockholders will have any economic interest in, or approval or other rights with respect to, the Post-Closing Merger.

Reasons for the Offer (Page 35)
Offeror is making the Offer and Allergan plans to complete the Inamed Merger because it believes that the acquisition of Inamed by Allergan will provide significant beneficial long-term growth prospects for the combined company and increase stockholder value, including for those Inamed stockholders who receive shares of Allergan common stock in the Offer or the Inamed Merger. Allergan believes that the Offer and the Inamed Merger will increase its market presence and opportunities, enhance its product mix, increase operating efficiencies, combine significant management talent and enhance employee opportunities.
Background of the Offer (Page 36)
On March 20, 2005, Inamed, Medicis and Masterpiece Acquisition Corp., a wholly owned subsidiary of Medicis, entered into an Agreement and Plan of Merger, pursuant to which Inamed would merge into Masterpiece Acquisition Corp. (the “Medicis Merger”). On December 13, 2005, Medicis and Inamed announced that the Medicis merger agreement had been mutually terminated. Under the terms of the now terminated Medicis merger agreement, each Inamed Share would have been cancelled in exchange for $30.00 in cash and 1.4205 shares of Medicis Class A common stock.
Allergan Proposal
On November 14, 2005, Allergan submitted a letter to Inamed with a proposal to acquire Inamed, for a per Inamed Share consideration of $84.00 in cash or 0.8498 of a share of Allergan common stock, at the election of the holder. In the letter, Allergan advised Inamed that Allergan and its advisors were prepared to immediately proceed with due diligence and negotiation of a definitive agreement with respect to the Offer and the Inamed Merger, consistent with the terms and conditions described herein and otherwise containing representations and warranties, covenants, conditions, terms and conditions substantially similar to those in the Medicis merger agreement. The text of this letter is included in “Background of the Offer.”
In accordance with the terms of the Medicis merger agreement, Inamed’s board of directors determined in good faith after consultation with its legal and financial advisors that Allergan’s proposal was reasonably likely to result in a transaction with terms more favorable to Inamed’s stockholders than the transaction

contemplated by the Medicis merger agreement. Therefore, Allergan and Inamed entered into a confidentiality agreement, as required by the terms of the Medicis merger agreement, and began discussions and negotiations regarding the terms of a definitive merger agreement.
On December 6, 2005, Allergan executed and delivered to Inamed an irrevocable offer letter accompanied by an executed definitive agreement and plan of merger (the “Allergan Merger Agreement”) for the proposed business combination transaction involving Allergan, Offeror and Inamed. The offer letter provided that Inamed could accept the offer set forth in the offer letter at any time after the Medicis merger agreement was terminated and after receipt of notice from Allergan that the conditions to the irrevocable offer set forth in the offer letter had been met. The text of the irrevocable offer letter is included in “Background to the Offer.”
After receipt of the irrevocable offer letter and Allergan Merger Agreement, Inamed issued a press release on December 6, 2005, announcing that its board of directors has determined that the Allergan Merger Agreement and the offer set forth therein are fair to Inamed’s stockholders and constitute a “Company Superior Proposal” (as such term was defined in the Medicis merger agreement) when compared to the Medicis merger agreement.
A letter confirming that the conditions to Inamed’s execution of the definitive Allergan Merger Agreement was sent by Allergan to Inamed on December 20, 2005, shortly before the parties executed the Allergan Merger Agreement.
See “Background of the Offer.”
Termination of the Medicis Merger Agreement
As noted above, on December 13, 2005, Inamed and Medicis each announced the termination of the Medicis merger agreement pursuant to a Merger Termination Agreement providing that the Medicis merger agreement would be terminated effective upon the execution of the Merger Termination Agreement and Medicis’ receipt from Inamed of a termination fee of $90,000,000 and reimbursement of $481,985 with respect to certain Medicis expenses. The Merger Termination Agreement also provides for a mutual release of certain claims in connection with the termination of the Medicis merger agreement.
According to public filings made by Inamed and Medicis with the SEC on December 13, 2005, the termination fee and expense reimbursement payments were paid in full by Inamed on December 13, 2005 and the Medicis merger agreement was terminated in its entirety at such time. In connection with such termination, Inamed announced the cancellation of the special meeting of Inamed stockholders scheduled for December 19, 2005.
Recommendation of the Inamed Board
On December 13, 2005, Inamed filed an amendment to its Solicitation/ Recommendation Statement on Schedule 14D-9 initially filed with the SEC on December 5, 2005 and subsequently amended. That amendment disclosed that on December 13, 2005 Inamed’s board of directors determined that the terms of the exchange offer set forth in the Allergan Merger Agreement and the Allergan Merger Agreement are advisable, fair to and in the best interests of the Inamed stockholders, and resolved to recommend that the Inamed stockholders tender their Inamed Shares pursuant to the Offer upon Inamed’s execution of the Allergan Merger Agreement and the amendment of the Offer to conform to the terms of the exchange offer set forth in the Allergan Merger Agreement.
At meetings held on December 13 and 14, 2005, Inamed’s board of directors:
•  formally and unanimously approved and adopted the terms of the Allergan Merger Agreement;
 
•  approved the exchange offer and the mergers contemplated by the Allergan Merger Agreement such that Section 203 of the Delaware General Corporation Law would not apply to such transactions;
 
•  approved the amendment of Inamed’s stockholder rights agreement to provide that the execution of the Allergan Merger Agreement and the consummation of the transactions contemplated by the Allergan Merger Agreement would not trigger the rights plan; and

•  resolved to recommend that Inamed Stockholders tender their shares pursuant to the offer contemplated by the Allergan Merger Agreement.
Antitrust Filings
On December 15, 2005, Allergan received a request for additional information and documentary material, referred to as a second request, from the Federal Trade Commission (“FTC”), pursuant to the Hart-Scott-Rodino Antitrust Improvements Act, as amended (the “HSR Act”), in connection with the Offer and the Inamed Merger. The second request extends the waiting period imposed by the HSR Act until thirty days after Allergan has substantially complied with such request. Allergan has been working with the FTC staff concerning the divestiture of Reloxin® and had anticipated the issuance of the second request as part of that process. Allergan does not expect the second request to result in a material delay in consummation of the transaction. The FTC may also allow Allergan to close the transaction before the expiration of the waiting period in the event that Allergan and the FTC agree on the terms of a consent order providing for the divestiture of Reloxin. If a divestiture plan can be developed that is acceptable to the FTC, the FTC will terminate its second request and will allow the transaction to close pursuant to the terms of a consent order. Allergan is currently working with the FTC staff to negotiate the terms of a divestiture plan and consent order that are acceptable to the FTC. While there can be no assurance of the outcome of these negotiations, Allergan does not anticipate that this process will result in any material delay in closing.
On December 20, 2005, Inamed and Ipsen entered into a termination agreement pursuant to which, subject to the consummation of Allergan’s acquisition of Inamed and certain other conditions, all rights related to Ipsen’s Botulinum Toxin type A pharmaceutical product previously granted by Ipsen to Inamed would be returned to Ipsen, and all worldwide rights in the Reloxin® trademark would be assigned to Ipsen. Under the terms and subject to the conditions of that agreement, the return of the rights to the Botulinum Toxin type A pharmaceutical product to Ipsen, and the assignment of the worldwide rights in the Reloxin® trademark to Ipsen would be made in consideration for payment by Ipsen of ten million US dollars to Inamed.
Listing Application
On December 19, 2005, Allergan submitted an application to list the shares of Allergan common stock to be issued pursuant to the Offer and the Inamed Merger on the NYSE. The authorization of the listing of such additional shares of Allergan common stock on the NYSE, subject to official notice of issuance, is a condition to the Offer, as described in “The Offer—Conditions of the Offer.”
Execution of the Allergan Merger Agreement
On December 20, 2005, Allergan provided written notice to Inamed pursuant to the irrevocable offer letter that Allergan was satisfied with its limited due diligence review of the Juvederm® information provided by Inamed and is satisfied with the Inamed disclosure schedules to the Allergan Merger Agreement. Subsequent to receiving such written notice, Inamed executed and delivered the Allergan Merger Agreement to Allergan.
Amendment of the Offer Terms
On December 20, 2005, Allergan amended the terms and conditions of the Offer to conform to the terms specified in the Allergan Merger Agreement and recommended by Inamed to its stockholders, as described above.
Plans for Inamed (Page 74)
Allergan has caused Offeror to make the Offer in order to acquire control of, and ultimately the entire equity interest in, Inamed. The Offer is the first step in Allergan’s acquisition of Inamed and is intended to facilitate Allergan’s acquisition of all of the outstanding equity ownership of Inamed. Allergan intends to seek to consummate the Inamed Merger and Post-Closing Merger as soon as possible after completing the Offer, in order to acquire all Inamed Shares not exchanged pursuant to the Offer.
After the Inamed Merger and the Post-Closing Merger, Allergan expects to continue Inamed’s current operations, except that Allergan expects that Inamed’s license to the Reloxin products will be divested for all markets. As noted above, on December 20, 2005, Inamed and Ipsen entered into a termination agreement

Table of Contents

pursuant to which, subject to the consummation of Allergan’s acquisition of Inamed and certain other conditions, all rights related to Ipsen’s Botulinum Toxin type A pharmaceutical product previously granted by Ipsen to Inamed would be returned to Ipsen, and all worldwide rights in the Reloxin® trademark would be assigned to Ipsen. In connection with the divestiture, Allergan will cooperate fully with any third-party acquiring Inamed’s rights in the Reloxin products, to ensure such third-party is able to benefit from all of Inamed’s information, studies, reports, and the U.S. Food and Drug Administration (“FDA”) filings and communications associated with the Reloxin products for such subsequent licensee to obtain regulatory approval for Reloxin. Inamed’s interest in the Reloxin license and the associated assets are referred to in this prospectus as the “Reloxin Assets.” See “The Offer— Plans for Inamed.”
The Offer is Scheduled to Expire on January 9, 2006 (Page 62)
The Offer currently is scheduled to expire at 5:00 p.m., New York City time, on Monday, January 9, 2006. The term “expiration date” as used in this prospectus means 5:00 p.m., New York City time, on Monday, January 9, 2006, unless Offeror extends the period of time for which the Offer is open, in which case the term “expiration date” means the latest time and date on which the Offer, as so extended, expires.
The Offer is Subject to Conditions (Page 63)
Offeror’s obligation to exchange Inamed Shares for cash or shares of Allergan’s common stock pursuant to the Offer is subject to a number of conditions, including, but not limited to, the following:
  the representations and warranties of Inamed contained in the Allergan Merger Agreement shall be true and correct, except where the failure of such representations and warranties to be true and correct (without giving effect to any limitation as to “materiality” or “Company Material Adverse Effect” set forth therein) would not, individually or in the aggregate, result in a Company Material Adverse Effect (as defined in the Allergan Merger Agreement);
 
  Inamed shall have performed in all material respects all of its obligations required to be performed by it under the Allergan Merger Agreement at or prior to the time Offeror accepts for exchange Inamed Shares validly tendered pursuant to the Offer;
 
  there shall have been validly tendered and not properly withdrawn prior to the expiration date at least a majority of the outstanding Inamed Shares (on a fully diluted basis); and
 
  any applicable waiting periods under the HSR Act, and any other applicable similar foreign laws or regulations, will have expired or been terminated.
No tender of Inamed Shares shall be effective, and Offeror shall not acquire tendered Inamed Shares, until all conditions have been satisfied or, to the extent permissible, waived. These conditions and the other conditions to the Offer are discussed under “The Offer— Conditions of the Offer.”
The Offer May Be Extended, Terminated or Amended (Page 62)
Under the Allergan Merger Agreement, Offeror must extend the period of time during which the Offer remains open in increments of no more than 10 business days each, if at the scheduled expiration date any of the conditions of the Offer have not been satisfied or waived, and Offeror also must extend the Offer for any period required by the SEC applicable to the Offer. The Allergan Merger Agreement provides that the agreement may be terminated if the Offer has not been consummated on or before February 28, 2006, subject to extension until March 30, 2006, under certain conditions. Offeror can extend the Offer by giving oral or written notice of the extension to the exchange agent. During any extension, all Inamed Shares previously tendered and not properly withdrawn will remain subject to the Offer, subject to the right of each Inamed stockholder to withdraw previously tendered Inamed Shares.
Subject to applicable SEC rules and regulations, Offeror also reserves the right, in its sole discretion, at any time or from time to time:
  to extend the Offer one time only for up to five business days if less than 90% of the total Inamed Shares on a fully diluted basis have been validly tendered and not properly withdrawn at the otherwise scheduled expiration date; or

7


Table of Contents

to waive any condition identified as subject to waiver in “The Offer—Conditions of the Offer;”
by giving oral or written notice of such termination, waiver or amendment to the exchange agent.
Offeror will make a public announcement promptly after any extension, delay, termination, waiver or amendment. In the case of an extension, any related announcement will be issued no later than 9:00 a.m., New York City time, on the first business day following the previously scheduled expiration date. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require that any material change in the information published, sent or given to Inamed stockholders in connection with the Offer be promptly sent in a manner reasonably designed to inform them of that change), and without limiting the manner in which Offeror may choose to make any public announcement, Offeror assumes no obligation to publish, advertise or otherwise communicate any public announcement of this type other than by issuing a press release to the Dow Jones News Service.
No subsequent offering period will be available following the expiration of the Offer.
Tendered Inamed Shares May Be Withdrawn at Any Time Prior to the Expiration Date (Page 66)
Tendered Inamed Shares may be withdrawn at any time prior to the expiration date, and, unless previously accepted pursuant to the Offer, may be withdrawn at any time after January 20, 2006. Once Offeror accepts Inamed Shares for exchange pursuant to the Offer, all tenders not previously withdrawn become irrevocable.
Procedure for Tendering Inamed Shares (Page 67)
To validly tender Inamed Shares pursuant to the Offer, Inamed stockholders must:
deliver a properly completed and duly executed letter of election and transmittal, along with any required signature guarantees and any other required documents, and certificates for tendered Inamed Shares to the exchange agent at one of its addresses set forth on the back cover of this prospectus, all of which must be received by the exchange agent at one of those addresses prior to the expiration date; or
 
deliver an agent’s message in connection with a book-entry transfer, and any other required documents, to the exchange agent at one of its addresses set forth on the back cover of this prospectus, and Inamed Shares must be tendered pursuant to the procedures for book entry tender set forth herein (and a confirmation of receipt of that tender received), and in each case be received by the exchange agent prior to the expiration date; or
 
stockholders must comply with the guaranteed delivery procedures set forth in “The Offer— Guaranteed Delivery.”
Inamed stockholders who hold Inamed Shares in “street name” through a bank, broker or other nominee holder, and desire to tender their Inamed Shares pursuant to the Offer, should instruct the nominee holder to do so prior to the expiration date.
The Exchange Shall Occur Promptly After the Expiration Date (Page 65)
Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any extension or amendment), promptly after the expiration date, Offeror will accept for exchange, and will exchange, all Inamed Shares validly tendered and not properly withdrawn prior to the expiration date.
Election and Proration Procedures (Page 60)
Inamed stockholders may elect to receive cash or shares of Allergan common stock, subject to the elections and proration procedure described in this prospectus, by indicating their tender offer elections in the applicable section of the letter of election and transmittal. Inamed stockholders are not required to exchange all of their Inamed Shares for one form of consideration or the other. Instead, if they own more than one Inamed Share, they may elect to receive cash in exchange for some of their Inamed Shares and shares of Allergan common stock in exchange for the remainder of their Inamed Shares. If an Inamed stockholder decides to change its election after tendering its Inamed Shares, it must first withdraw the tendered shares and then re-tender the

Table of Contents

Inamed Shares prior to the expiration date, with a new letter of election and transmittal that indicates the revised election.
Regulatory Requirements (Page 76)
The Offer and the Inamed Merger cannot be consummated until certain information that Allergan has furnished to the Antitrust Division of the Department of Justice (the “DOJ”) and the FTC has been reviewed and certain waiting period requirements have been satisfied. These requirements and other issues are discussed under “The Offer— Certain Legal Matters; Regulatory Approvals.”
Source and Amount of Funds (Page 78)
The Offer and the Inamed Merger are not conditioned upon any financing arrangements or contingencies.
Offeror estimates that the total purchase price for all of the outstanding Inamed Shares proposed to be acquired pursuant to the Offer and the Inamed Merger, including associated fees and expenses, will be approximately $3.4 billion, including $1.6 billion in cash. Allergan has received a commitment letter from Morgan Stanley Senior Funding, Inc., an affiliate of Morgan Stanley & Co. Incorporated, providing for a 364-day bridge term facility in an aggregate amount of up to $1.1 billion. Any proceeds of this facility will be used solely to acquire Inamed Shares tendered in the Offer and pursuant to the Inamed Merger and to pay associated transaction fees and expenses.
Dividend Policy of Allergan (Page 80)
The holders of shares of Allergan common stock receive dividends if and when declared by Allergan’s board of directors out of legally available funds. For the past three fiscal quarters, including the quarter ended September 30, 2005, Allergan has paid a cash dividend of $0.10 per share per quarter, increased from the $0.09 per share paid per quarter in each of the prior eight quarters. Allergan’s declaration and payment of cash dividends in the future will depend upon its results of operations, financial condition, cash requirements, prospects, limitations imposed by credit agreements or debt securities and other factors deemed relevant by its board of directors. Certain financial covenants set forth in Allergan’s current bank credit line agreements and other financing agreements (including the commitment letter from Morgan Stanley discussed above) restrict its ability to declare dividends. Allergan can give stockholders no assurance that Allergan will continue to pay any dividends on its common stock in the future at historical levels or at all.
No Appraisal Rights in Connection with the Offer (Page 73)
No appraisal rights are available in connection with the Offer. However, Inamed stockholders would have appraisal rights under Delaware law in connection with the Inamed Merger.
Comparative Per Share Market Price Information (Page 25)
Shares of Allergan common stock are listed on the New York Stock Exchange under the symbol “AGN.” Inamed Shares trade on the NASDAQ National Market under the symbol “IMDC.” On November 14, 2005, the last full trading day before Allergan announced its proposal to acquire Inamed, the closing sales price of Allergan common stock on the New York Stock Exchange was $98.85 and the closing sales price of Inamed Shares on the NASDAQ National Market was $74.44. On December 21, 2005, the most recent practicable date prior to the date of this prospectus, the closing sales price of Allergan common stock was $107.31 and the closing sales price of an Inamed Share was $87.02. Inamed stockholders should obtain current market quotations for Allergan common stock and Inamed Shares before deciding whether to tender Inamed Shares in the Offer and before electing the form of Offer consideration they wish to receive. See “Comparative Market Price Data.”
Ownership of Allergan After the Offer (Page 70)
Allergan estimates that if all Inamed Shares are exchanged pursuant to the Offer and the Inamed Merger, former Inamed stockholders would own, in the aggregate approximately 11% of the shares of Allergan common stock outstanding after the Inamed Merger. For a detailed discussion of the assumptions on which this estimate is based, see “The Offer— Ownership of Allergan After the Offer and the Inamed Merger.”

Table of Contents

Material Differences in Rights of Stockholders (Page 93)
The rights of Allergan stockholders are different in some respects from the rights of Inamed stockholders. Therefore, Inamed stockholders will have different rights as stockholders once they become Allergan stockholders. The differences are described in more detail under “Comparison of Stockholders’ Rights.”
Tax Considerations (Page 70)
In the opinion of Gibson, Dunn & Crutcher LLP, Allergan’s tax counsel, the Offer, the Inamed Merger and the Post-Closing Merger will be treated as a single integrated transaction that qualifies as a reorganization under Section 368(a) of the Internal Revenue Code (the “Code”). This opinion is given in reliance on customary representations and assumptions as to certain factual matters. See “The Offer— Material U.S. Federal Income Tax Consequences.”
In the opinion of Gibson, Dunn & Crutcher LLP, the tax consequences to Inamed stockholders who receive their shares of Allergan common stock and/or cash in exchange for shares of Inamed stock pursuant to a transaction constituting a reorganization within the meaning of Section 368(a) of the Code will generally be as follows:
an Inamed stockholder who exchanges all of its Inamed Shares for shares of Allergan common stock in the Offer and/or the Inamed Merger, will not recognize any gain or loss from the exchange, except with respect to cash received in lieu of fractional shares of Allergan common stock;
 
an Inamed stockholder who exchanges all of its Inamed Shares for cash in the Offer and/or Inamed Merger, generally will recognize gain or loss in the exchange equal to the difference between the aggregate amount of cash received for the Inamed Shares and the stockholder’s tax basis in those Inamed Shares; and
 
an Inamed stockholder who exchanges its Inamed Shares for both shares of Allergan common stock and cash in the Offer and/or the Inamed Merger will recognize gain, but not loss in the exchange, equal to the lesser of (a) the amount of cash received in the transaction and (b) the amount of gain realized in the transaction. The amount of gain that is realized in the exchange will equal the excess of (i) the sum of the cash plus the fair market value of the Allergan common stock received in the exchange over (ii) the tax basis of the shares of Inamed common stock surrendered in the transaction.
Inamed stockholders should carefully read the discussion under “The Offer— Material U.S. Federal Income Tax Consequences,” and consult their tax advisors on the consequences of participation in the Offer or the Inamed Merger.
Accounting Treatment (Page 79)
The acquisition of Inamed by Allergan will be accounted for as a purchase for financial reporting purposes.

RISK FACTORS
      Inamed stockholders should carefully read this prospectus and the other documents referred to or incorporated by reference into this prospectus, including in particular the following risk factors, in deciding whether to tender Inamed Shares pursuant to the Offer.
Risk Factors Relating to the Offer
The transaction may adversely affect the liquidity and value of the Inamed Shares not tendered.
      If the Offer is completed but all Inamed Shares are not tendered in the Offer, the number of stockholders and the number of Inamed Shares publicly held will be greatly reduced. As a result, the closing of the Offer could adversely affect the liquidity and market value of the remaining Inamed Shares held by the public. In addition, following completion of the Offer, subject to the rules of the NASDAQ National Market, Inamed may seek to delist the Inamed Shares from the NASDAQ National Market. As a result of any such delisting, Inamed Shares not tendered pursuant to the Offer may become illiquid and may be of reduced value. See “The Offer— Plans for Inamed.”
Inamed has not been involved in the preparation of the information contained in this prospectus, and such information may be inaccurate or incomplete.
      Allergan has relied upon information publicly filed by Inamed with the SEC for all information relating to Inamed presented in, or incorporated by reference into, this prospectus. Although neither Allergan nor Offeror has any knowledge that any such information or statements contain or incorporated by reference herein regarding Inamed’s condition, including its financial or operating condition, are inaccurate, incomplete or untrue, neither Allergan nor Offeror were involved in the preparation of such information and statements. In addition, Allergan has made adjustments and assumptions in preparing the pro forma financial information presented in this prospectus that have necessarily involved Allergan’s estimates with respect to Inamed’s financial information. Any financial, operating or other information regarding Inamed that may be detrimental to Allergan following Offeror’s acquisition of Inamed that has not been publicly disclosed by Inamed, or errors in Allergan’s estimates due to Allergan’s inability to gain full access to Inamed’s non-public information, may have an adverse effect on the benefits Allergan expects to achieve through the consummation of the Offer, the Inamed Merger and the Post-Closing Merger.
The market price of Allergan common stock may decline as a result of Allergan’s acquisition of Inamed.
      The market price of Allergan’s common stock may decline after the Offer and Inamed Merger are completed if:
  the integration of Inamed’s business is unsuccessful or takes longer or is more disruptive than anticipated;
 
  information regarding Inamed that has not been publicly disclosed has an adverse effect on the combined company’s profitability or results of operations;
 
  after Allergan acquires Inamed, Allergan learns of information with respect to Inamed that prevents Allergan from making the certifications required by the Sarbanes-Oxley Act of 2002, which could reduce investors’ confidence in Allergan’s reporting capabilities with respect to Inamed’s business;
 
  Allergan does not achieve the expected synergies or other benefits of the Inamed acquisition as rapidly or to the extent anticipated, if at all;
 
  the effect of Allergan’s acquisition of Inamed on Allergan’s financial results does not meet the expectations of Allergan, financial analysts or investors;
 
  after Allergan acquires Inamed, Inamed’s business does not perform as anticipated; or
 
  Allergan’s credit rating is downgraded as a result of Allergan’s increased indebtedness incurred to finance the Offer and the Inamed Merger.

Table of Contents

      As of December 14, 2005 there were 134,254,772 shares of Allergan common stock outstanding (including 1,563,978 shares held in treasury), and options outstanding to purchase an additional 10,861,695 shares. In connection with the Offer and Inamed Merger, Allergan estimates that Allergan could issue approximately 17,875,862 additional shares of Allergan common stock. The increase in the number of outstanding shares of Allergan common stock may lead to sales of such shares or the perception that such sales may occur, either of which may adversely affect the market price of Allergan common stock.
Uncertainties exist in integrating the business and operations of Allergan and Inamed.
      After Allergan’s acquisition of Inamed, Allergan expects to continue Inamed’s current operations, other than those related to the Reloxin Assets. However, Allergan intends to integrate certain of Inamed’s and Allergan’s functions and operations. Although Allergan believes the integration will be successfully completed, there can be no assurance that Allergan will be able to successfully integrate Inamed’s operations with those of Allergan. There will be inherent challenges in integrating the companies’ operations that could result in a delay or the failure to achieve the anticipated synergies and, therefore, any potential increases in earnings and cost savings. Issues that must be addressed in integrating the operations of the companies include, among other things:
  conforming standards, controls, procedures and policies, business cultures and compensation structures between Inamed and Allergan;
 
  consolidating corporate and administrative infrastructures;
 
  consolidating sales and marketing operations;
 
  retaining existing customers and attracting new customers;
 
  retaining key employees;
 
  identifying and eliminating redundant and underperforming operations and assets;
 
  minimizing the diversion of management’s attention from ongoing business concerns;
 
  coordinating geographically dispersed organizations;
 
  managing tax costs or inefficiencies associated with integrating the operations of the combined company; and
 
  possibly modifying operating control standards to comply with the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder.
      If Allergan is not able to successfully address these challenges, Allergan may be unable to successfully integrate the companies’ operations, or to realize the anticipated benefits of the integration of the two companies. Actual cost and sales synergies, if achieved at all, may be lower than Allergan currently expects and may take a longer time to achieve than Allergan currently anticipates.
Even if the Offer is completed, full integration of Inamed’s operations with Allergan’s may be delayed if Offeror does not acquire at least 90% of the issued and outstanding Inamed Shares pursuant to the Offer.
      The Offer is subject to a condition that, before the expiration date, there shall have been validly tendered and not properly withdrawn at least a majority of the Inamed Shares on a fully diluted basis. If Offeror acquires at least 90% of the issued and outstanding Inamed Shares, the Inamed Merger will be able to be effected as a “short-form” merger under Delaware law. A short-form merger would enable Allergan to complete the acquisition of Inamed without any action on the part of the other holders of Inamed Shares. If Allergan does not acquire 90% of the issued and outstanding Inamed Shares, Allergan will be required to obtain the approval of Inamed stockholders to consummate the Inamed Merger. Although this will not prevent the Inamed Merger or Post-Closing Merger from occurring, as Offeror will hold sufficient Inamed Shares to approve the Inamed Merger, it would delay Allergan from completing the Inamed Merger and could

12


Table of Contents

delay the realization of some or all of the anticipated benefits from integrating Inamed’s operations with Allergan’s operations.
Antitrust authorities may attempt to delay or prevent Offeror’s acquisition of Inamed.
      Allergan made a premerger filing under the HSR Act with the FTC and Antitrust Division of the DOJ on November 15, 2005. On December 15, 2005, Allergan received a request for additional information and documentary material, referred to as a second request, from the FTC, pursuant to the HSR Act, in connection with the Offer and the Inamed Merger. The effect of the second request is to extend the waiting period imposed by the HSR Act until thirty days after Allergan has substantially complied with such request. Until the applicable waiting period under the HSR Act expires or is terminated, Offeror may not purchase any Inamed Shares. In addition, Allergan has determined that it is required to file notifications of the Offer and Inamed Merger with the antitrust authorities in Spain and Germany. Allergan filed the requisite notifications in Germany on December 8, 2005 and in Spain on December 9, 2005. Until the applicable waiting periods under the laws of Germany and Spain expire or are terminated by the authorities in those jurisdictions, Offeror may not purchase any Inamed Shares.
      In order to minimize any potential antitrust issues, Allergan will agree to immediately divest itself of the Reloxin Assets in connection with the Offer. Inamed and Ipsen have entered into a termination agreement pursuant to which, subject to the consummation of Allergan’s acquisition of Inamed and certain other conditions, all rights related to Ipsen’s Botulinum Toxin type A pharmaceutical product previously granted by Ipsen to Inamed would be returned to Ipsen, and all worldwide rights in the Reloxin® trademark would be assigned to Ipsen. However, Allergan cannot provide any assurance that the necessary approvals will be obtained or that there will not be any adverse consequences to the business of Allergan or Inamed resulting from conditions that could be imposed in connection with obtaining these approvals, including other divestitures or operating restrictions upon Inamed or the combined company. The Offer is conditioned upon the receipt of all required antitrust approvals or clearances for Allergan’s acquisition of Inamed, without Allergan, Inamed or any of Allergan’s subsidiaries being required to meet any condition or restriction that would be materially adverse to the combined company, other than the divestiture of the Reloxin Assets, and no court or other authority prohibiting the consummation of the Offer, the Inamed Merger or the Post-Closing Merger. Inamed stockholders should be aware that all required regulatory approvals may not be timely obtained and could result in a significant delay in the consummation of the Offer, the Inamed Merger or the Post-Closing Merger.
Inamed stockholders who receive Allergan common stock in the Offer will become Allergan stockholders. Allergan’s common stock may be affected by different factors and holders will have different rights than those as Inamed stockholders.
      Upon completion of the Offer, Inamed stockholders receiving shares of Allergan common stock will become stockholders of Allergan. Allergan’s business differs from that of Inamed, and Allergan’s results of operations and the trading price of Allergan common stock may be adversely affected by factors different from those that would affect Inamed’s results of operations and stock price.
      In addition, holders of shares of Allergan common stock will have different rights as stockholders than those rights they had as Inamed stockholders before the Offer or the Inamed Merger. For a detailed comparison of the rights of Allergan stockholders compared to the rights of Inamed stockholders, see “Comparison of Stockholders’ Rights.”
Inamed stockholders may not receive all consideration in the form elected.
      At the time Inamed stockholders tender their Inamed Shares and make an election, they will not know exactly what combination of cash and shares of Allergan common stock they will receive because it will also depend upon the elections made by other tendering stockholders. Each tendering Inamed stockholder will receive either cash, shares of Allergan common stock, or a combination of cash and shares of Allergan common stock, based upon their election and the elections of other tendering stockholders. To the extent that

13


Table of Contents

the demand for either cash or stock consideration exceeds the aggregate amount of cash or Allergan common stock available in the Offer, Offeror will prorate the total cash or stock, as the case may be, proportionally among the stockholders who elect the form of consideration for which elections exceed availability. Inamed stockholders who do not make an election will be allocated whatever consideration is remaining (or a proportionate share of each consideration if neither is oversubscribed), after taking into account the elections of tendering stockholders who make elections.
The receipt of shares of Allergan common stock in the Offer and/or the Inamed Merger may be taxable to Inamed stockholders.
      If the Offer, the Inamed Merger and the Post-Closing Merger are not treated as an integrated transaction for United States federal income tax purposes, if the Inamed Merger or the Post-Closing Merger is not completed, or if the transaction otherwise fails to qualify as a tax-free reorganization, the exchange of Inamed Shares for shares of Allergan common stock in the Offer and/or the Inamed Merger will be taxable to such stockholders for U.S. federal income tax purposes. In the opinion of Gibson, Dunn & Crutcher LLP, the Offer, the Inamed Merger and the Post-Closing Merger will be treated as an integrated transaction that qualifies as a tax-free reorganization under Section 368(a) of the Code. The opinion of Gibson, Dunn & Crutcher LLP assumes a number of factors that will not be definitively known prior to completion of the Offer, the Inamed Merger and the Post-Closing Merger. In addition, the opinion of Gibson, Dunn & Crutcher LLP will not be binding on the Internal Revenue Service and there can be no assurance that the Internal Revenue Service will not challenge the conclusion set forth therein. For more information, see “The Offer— Material U.S. Federal Income Tax Consequences” and the opinion of Gibson, Dunn & Crutcher LLP attached as Annex C to this prospectus.
Inamed stockholders should consult their tax advisors to determine the specific tax consequences to them of the Offer, the Inamed Merger and the Post-Closing Merger, including any federal, state, local, foreign or other tax consequences, and any tax return filing or other reporting requirements.
Risks Factors Relating to the Business of Allergan and the Combined Company
      The results of operations of Allergan and the combined company will be subject to numerous risks affecting the business of Allergan and Inamed. Inamed and Allergan operate in a rapidly changing environment that involves a number of risks. The risks described below and other risks discussed elsewhere in this prospectus and Allergan’s SEC filings could materially and adversely affect the business, financial condition, prospects, operating results or cash flows of the combined company. For a discussion of additional risk factors that affect the business of Inamed, see the discussion “Risks and Uncertainties” in Inamed’s Form 10-Q for the quarter ended September 30, 2005 and Inamed’s other SEC filings.
Allergan’s indebtedness following the Offer will be greater than Allergan’s existing indebtedness, which may increase its vulnerability to adverse financial conditions.
      Allergan’s total indebtedness as of September 30, 2005 was approximately $701.6 million. Allergan’s pro forma total indebtedness as of September 30, 2005, after giving effect to the acquisition of 100% of the outstanding Inamed Shares will be approximately $1,746.6 million, as described in “Unaudited Pro Forma Combined Condensed Financial Statements.” Allergan’s debt service obligations with respect to this increased indebtedness could have an adverse impact on its earnings and cash flows for as long as the indebtedness is outstanding.
      Allergan’s increased indebtedness could have important consequences to holders of Allergan common stock, including former Inamed stockholders who receive Allergan shares in the Offer. For example, it could:
  make it more difficult for Allergan to pay its debts as they become due upon the occurrence of any adverse economic conditions, either generally or in its industry or geographic areas in which it operates, because any related decrease in revenues could cause Allergan to not have sufficient cash flows from operations to make its scheduled debt payments;

14


Table of Contents

  limit Allergan’s flexibility in planning for, or reacting to, changes in its business and the industry in which it operates and, consequently, place Allergan at a competitive disadvantage to its competitors;
 
  require a substantial portion of Allergan’s cash flows from operations be used to service debt, thereby reducing its ability to fund research and development, working capital, capital expenditures, acquisitions and other corporate purposes;
 
  result in acceleration of the payment on Allergan’s existing debt or a downgrade in Allergan’s credit rating, which could limit Allergan’s ability to borrow additional funds or increase the interest rates and restrictions applicable to Allergan’s indebtedness; and
 
  result in higher interest expense in the event of increases in interest rates, as some of Allergan’s borrowings are, and will continue to be, at variable rates of interest.
      There can be no assurance that Allergan will be able to pay all principal and interest payments when due under Allergan’s existing and proposed credit facilities, and the indenture governing Allergan’s currently outstanding notes. See “The Offer— Source and Amount of Funds.”
The terms of Allergan’s existing and proposed debt agreements impose many restrictions on Allergan. Failure to comply with these restrictions could result in acceleration of Allergan’s debt. Were this to occur, Allergan might not have, or be able to obtain, sufficient cash to pay its accelerated indebtedness.
      The operating and financial restrictions and covenants in Allergan’s existing and proposed debt agreements may adversely affect Allergan’s ability to finance future operations or capital needs or to engage in new business activities. Allergan’s existing and proposed debt agreements restrict, or are expected to restrict, Allergan’s ability to, among other things:
  incur subsidiary debt;
 
  incur liens;
 
  engage in consolidations, mergers, and asset sales; and
 
  engage in transactions with affiliates.
      In addition, Allergan’s existing and proposed debt agreements include, or are expected to include, financial covenants that Allergan maintain certain financial ratios. As a result of these covenants and ratios, Allergan will have certain limitations on the manner in which it can conduct its business, and may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit Allergan’s ability to successfully operate its business. Failure to comply with the financial covenants or to maintain the financial ratios contained in the existing and proposed debt agreements could result in an event of default that could trigger acceleration of Allergan’s indebtedness. There can be no assurance that Allergan’s future operating results will be sufficient to ensure compliance with the covenants in its existing and proposed debt agreements or to remedy any such default. In addition, in the event of any default and related acceleration of obligations, Allergan may not have or be able to obtain sufficient funds to make any accelerated payments. See “The Offer— Source and Amount of Funds” and “Allergan’s Existing Debt Agreements.”
The pharmaceutical industry is a highly competitive business.
      The pharmaceutical industry is highly competitive. This competitive environment requires an ongoing, extensive search for technological innovation. It also requires, among other things, the ability to effectively develop, test, and obtain regulatory approvals for products, as well as the ability to effectively commercialize, market and promote approved products, including communicating the effectiveness, safety and value of products to actual and prospective customers and medical professionals. Many competitors of Allergan and Inamed have greater resources, enabling them, among other things, to spread their research and development costs, as well as their marketing and promotion costs, over a broader revenue base. Competitors may also have more experience and expertise in obtaining marketing approvals from the FDA and other regulatory

15


Table of Contents

authorities. In addition to product development, testing, approval and promotion, other competitive factors in the pharmaceutical industry include industry consolidation, product quality and price, reputation, customer service and access to technical information. It is possible that developments by competitors could make the combined company’s products or technologies less competitive or obsolete. In addition, competition from generic drug manufacturers is a major challenge in the United States and is growing internationally. For instance, Falcon Pharmaceuticals, Ltd., an affiliate of Alcon Laboratories, Inc., is currently attempting to obtain FDA approval for and to launch a brimonidine product to compete with Allergan’s Alphagan® P product.
      Until December 2000, Botox® was the only neuromodulator approved by the FDA. At that time, the FDA approved Myobloc®, a neuromodulator formerly marketed by Elan Pharmaceuticals and now marketed by Solstice Neurosciences, Inc. Allergan believes that Beaufour Ipsen Ltd. intends to seek FDA approval for its Dysport® neuromodulator for certain therapeutic indications, and Inamed, Beaufour Ipsen’s marketing partner, intends to seek FDA approval for Reloxin® for cosmetic indications. Beaufour Ipsen has marketed Dysport® in Europe since 1991, prior to Allergan’s European commercialization of Botox® in 1992. In connection with the Offer, Allergan will agree to divest to a third party all of Inamed’s rights and interests in Beaufour Ipsen’s Reloxin® for therapeutic and cosmetic indications. Inamed has announced that it is currently conducting Phase III trials for the product; and in connection with the divestiture of the Reloxin Assets, Allergan will cooperate fully with any subsequent licensee to ensure such licensee is able to benefit from all studies and trials conducted by Inamed to obtain regulatory approval for Reloxin®. Also, Mentor Corporation has announced its intention to develop and seek regulatory approval to market a competing neuromodulator in the United States. In addition, Allergan is aware of competing neuromodulators currently being developed and commercialized in Asia, Europe, South America and other markets. A Chinese entity received approval to market a botulinum toxin in China in 1997, and Allergan believes that it has launched or is planning to launch its botulinum toxin product in other lightly regulated markets in Asia, South America and Central America. These lightly regulated markets may not require adherence to the FDA’s current Good Manufacturing Practices, or cGMPs, the European Medical Evaluation Agency or other regulatory agencies in countries that are members of the Organization for Economic Cooperation and Development, and companies operating in these markets may be able to produce products at a lower cost than can Allergan. In addition, Merz Pharmaceuticals received approval from German authorities for a botulinum toxin and launched its product in July 2005, and a Korean company is conducting Phase III clinical trials for a botulinum toxin in Korea. This product received exportation approval from Korean authorities in early 2005. Allergan’s sales of Botox® could be materially and negatively impacted by this competition or competition from other companies that might obtain FDA approval or approval from other regulatory authorities to market a neuromodulator.
Botox® Cosmetic is a consumer product; trends may change. Changes in the consumer marketplace and applicable laws and economic conditions may adversely affect sales or product margins of Botox® or Botox® Cosmetic.
      Botox® Cosmetic is a consumer product. If Allergan fails to anticipate, identify or to react to competitive products or if consumer preferences in the cosmetic marketplace shift to other treatments for the temporary improvement in the appearance of moderate to severe glabellar lines, Allergan may experience a decline in demand for Botox® Cosmetic. In addition, the popular media has at times in the past produced, and may continue in the future to produce, negative reports and entertainment regarding the efficacy, safety or side effects of Botox® Cosmetic. Consumer perceptions of Botox® Cosmetic may be negatively impacted by these reports and for other reasons, including the use of unapproved botulinum toxins that result in injury, which may cause demand to decline.
      Demand for Botox® Cosmetic also may be materially adversely affected by changing economic conditions. Generally, the costs of cosmetic procedures are borne by individuals without reimbursement from their medical insurance providers or government programs. Individuals may be less willing to incur the costs of these procedures in weak or uncertain economic environments, and demand for Botox® Cosmetic could be adversely affected.

16


Table of Contents

      Because Botox® and Botox® Cosmetic are pharmaceutical products, Allergan does not generally collect or pay sales tax or other taxes on sales of Botox® or Botox® Cosmetic. Allergan could be required to collect and pay sales or other taxes associated with prior, current or future years on sales of Botox® or Botox® Cosmetic. In addition to any retroactive taxes and corresponding interest and penalties that could be assessed, if Allergan is required to collect or pay sales or other tax associated with current or future years on sales of Botox® or Botox® Cosmetic, its sales of, or product margins on, Botox® or Botox® Cosmetic could be adversely affected due to the increased cost associated with those products.
Allergan could experience difficulties creating the raw material needed to produce Botox® which would adversely affect sales.
      The manufacturing process to create the raw material necessary to produce Botox® is technically complex and requires significant lead-time. Any failure by Allergan to forecast demand for, or to maintain an adequate supply of, the raw material and finished product could result in an interruption in the supply of Botox® and a resulting decrease in sales of the product.
Allergan’s future success depends upon its ability to develop new products, and new indications for existing products, that achieve market acceptance.
      Allergan’s future performance will be affected by the market acceptance of products such as Lumigan®, Alphagan® P, Combigantm, Restasis®, Acular LS®, Zymar® and Botox®, as well as FDA approval of new indications for Botox®, and new products such as a Lumigan®/Timolol combination, Posurdex® and memantine. Allergan has allocated substantial resources to the development and introduction of new products and indications. For the business model of the combined company to be successful, new products must be continually developed, tested and manufactured and, in addition, must meet regulatory standards and receive requisite regulatory approvals in a timely manner. For instance, to obtain approval of new indications or products in the United States, a company must submit, among other information, the results of preclinical and clinical studies on the new indication or product candidate to the FDA. The number of preclinical and clinical studies that will be required for FDA approval varies depending on the new indication or product candidate, the disease or condition for which the new indication or product candidate is in development and the regulations applicable to that new indication or product candidate. If the FDA delays or does not approve of new indications for Allergan products or its new drug candidates, the price per share of Allergan common stock may be impacted upon the announcement of such delays or non-approvals. Allergan is also required to pass pre-approval reviews and plant inspections of its and its suppliers’ facilities to demonstrate compliance with the FDA’s cGMP regulations. Products that Allergan currently is developing or other future product candidates may or may not receive the regulatory approvals necessary for marketing. Furthermore, the development, regulatory review and approval, and commercialization processes are time consuming, costly and subject to numerous factors that may delay or prevent the development and commercialization of new products, including legal actions brought by its competitors. The FDA can delay, limit or deny approval of a new indication or product candidate for many reasons, including:
  a determination that the new indication or product candidate is not safe and effective;
 
  the FDA may interpret preclinical and clinical data in different ways than Allergan does;
 
  the FDA may not approve a manufacturing process or facility; or
 
  the FDA may change its approval policies or adopt new regulations.
      In connection with Allergan’s 2003 acquisitions of Bardeen Sciences Company, LLC and Oculex Pharmaceuticals, Inc., Allergan acquired the right to continue researching and developing certain compounds and products, for commercialization. It cannot be assured that these or any other compounds or products in development for commercialization will be able to be commercialized on terms that will be profitable, or at all. If any of Allergan’s products cannot be successfully or timely commercialized, its operating results could be materially adversely affected. Delays or unanticipated costs in any part of the process or the inability of Allergan to obtain timely regulatory approval for any products, including those attributable to, among other

17


Table of Contents

things, a failure to maintain manufacturing facilities in compliance with all applicable regulatory requirements, could cause its operating results to suffer and stock price to decrease. It cannot be assured that new products or indications will be successfully developed, will receive regulatory approval or will achieve market acceptance. Further, even if Allergan receives FDA and other regulatory approvals for a new indication or product, the product may later exhibit adverse effects that limit or prevent its widespread use or that force Allergan to withdraw the product from the market or to revise its labeling to limit the indications for which the product may be prescribed.
If Allergan is unable to obtain and maintain adequate patent protection for the technologies incorporated into its products, its business and results of operations could suffer.
      Patent protection is generally important in the pharmaceutical industry. Upon the expiration or loss of patent protection for a product, Allergan can lose a significant portion of sales of that product in a very short period of time as other companies manufacture generic forms of the previously protected product at lower cost, without having had to incur significant research and development costs in formulating the product. Therefore, Allergan’s future financial success may depend in part on obtaining patent protection for technologies incorporated into its products. It cannot be assured that such patents will be issued, or that any existing or future patents will be of commercial benefit. In addition, it is impossible to anticipate the breadth or degree of protection that any such patents will afford, and it cannot be assured that any such patents will not be successfully challenged in the future. If Allergan is unsuccessful in obtaining or preserving patent protections, or if any of Allergan’s products rely on unpatented proprietary technology, there can be no assurance that others will not commercialize products substantially identical to those products. Generic drug manufacturers currently are challenging the patents covering certain Allergan products and it is expected that they will continue to do so in the future. Allergan’s business also relies on trade secrets and proprietary know-how that it seeks to protect, in part, through confidentiality agreements with third parties, including with partners, customers, employees and consultants. It is possible that these agreements will be breached or that they will not be enforceable in every instance, and that Allergan will not have adequate remedies for any such breach. It is also possible that Allergan’s trade secrets will become known or independently developed by its competitors.
Interruptions in the supply of raw materials could disrupt Allergan’s manufacturing and cause its sales and profitability to decline.
      Allergan obtains the specialty chemicals that are the active pharmaceutical ingredients in certain of its products from single sources, who must maintain compliance with the FDA’s cGMP regulations. If Allergan experiences difficulties acquiring sufficient quantities of these materials from its existing suppliers, or if suppliers are found to be non-compliant with the cGMPs, obtaining the required regulatory approvals, including from the FDA, to use alternative suppliers may be a lengthy and uncertain process. A lengthy interruption of the supply of one or more of these materials could adversely affect Allergan’s ability to manufacture and supply products, which could cause its sales and profitability to decline.
Importation of products from Canada and other countries into the United States may lower the prices Allergan receives for its products.
      In the United States, Allergan’s products are subject to competition from lower priced versions of its products and competing products from Canada, Mexico, and other countries where government price controls or other market dynamics result in lower prices. Allergan’s products that require a prescription in the United States often are available to consumers in these markets without a prescription, which may cause consumers to further seek out these products in these lower priced markets. The ability of patients and other customers to obtain these lower priced imports has grown significantly as a result of the Internet, an expansion of pharmacies in Canada and elsewhere targeted to American purchasers, the increase in U.S.-based businesses affiliated with Canadian pharmacies marketing to American purchasers, and other factors. Most of these foreign imports are illegal under current U.S. law. However, the volume of imports continues to rise due to the

18


Table of Contents

limited enforcement resources of the FDA and the U.S. Customs Service, and there is increased political pressure to permit the imports as a mechanism for expanding access to lower priced medicines.
      In December 2003, Congress enacted the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. This law contains provisions that may change U.S. import laws and expand consumers’ ability to import lower priced versions of products of Allergan and its competitors from Canada, where there are government price controls. These changes to U.S. import laws will not take effect unless and until the Secretary of Health and Human Services certifies that the changes will lead to substantial savings for consumers and will not create a public health safety issue. The former Secretary of Health and Human Services did not make such a certification. However, it is possible that the current Secretary or a subsequent Secretary could make the certification in the future. As directed by Congress, a task force on drug importation recently conducted a comprehensive study regarding the circumstances under which drug importation could be safely conducted and the consequences of importation on the health, medical costs and development of new medicines for U.S. consumers. The task force issued its report in December 2004, finding that there are significant safety and economic issues that must be addressed before importation of prescription drugs is permitted, and the current Secretary has not yet announced any plans to make the required certification. In addition, federal legislative proposals have been made to implement the changes to the U.S. import laws without any certification, and to broaden permissible imports in other ways. Even if the changes to the U.S. import laws do not take effect, and other changes are not enacted, imports from Canada and elsewhere may continue to increase due to market and political forces, and the limited enforcement resources of the FDA, the U.S. Customs Service and other government agencies. For example, state and local governments have suggested that they may import drugs from Canada for employees covered by state health plans or others, and some already have implemented such plans.
      The importation of foreign products adversely affects Allergan’s profitability in the United States. This impact could become more significant in the future, and the impact could be even greater if there is a further change in the law or if state or local governments take further steps to import products from abroad.
Allergan’s business will continue to expose it to risks of environmental liabilities.
      Allergan’s product development programs and manufacturing processes involve the controlled use of hazardous materials, chemicals and toxic compounds. These programs and processes expose Allergan to risks that an accidental contamination could lead to noncompliance with environmental laws, regulatory enforcement actions and claims for personal injury and property damage. If an accident occurs, or if Allergan discovers contamination caused by prior operations, including by prior owners and operators of properties acquired, it could be liable for cleanup obligations, damages and fines. The substantial unexpected costs that Allergan may incur could have a significant and adverse effect on Allergan’s business and results of operations.
Allergan may experience losses due to product liability claims, product recalls or corrections.
      The design, development, manufacture and sale of Allergan’s products involves an inherent risk of product liability or other claims by consumers and other third parties. Allergan has in the past been, and continues to be, subject to various product liability claims and lawsuits. In addition, it has in the past and may in the future recall or issue field corrections related to its products due to manufacturing deficiencies, labeling errors or other safety or regulatory reasons. There can be no assurance that Allergan will not in the future experience material losses due to product liability claims, lawsuits, product recalls or corrections.
      Additionally, Allergan’s products may cause, or may appear to cause, serious adverse side effects or potentially dangerous drug interactions if misused or improperly prescribed. These events, among others, could result in additional regulatory controls, such as the performance by Allergan of costly post-approval clinical studies or revisions to approved labeling, which could limit the indications or patient population for its products or could even lead to the withdrawal of a product from the market. Furthermore, any adverse publicity associated with such an event could cause consumers to seek alternatives to Allergan’s products, which may cause its sales to decline, even if Allergan’s products are ultimately determined not to have been the primary cause of the event.

Health care initiatives and other cost-containment pressures could cause Allergan to sell its products at lower prices, resulting in decreased revenue.
      Some of Allergan’s products are purchased or reimbursed by state and federal government authorities, private health insurers and other organizations, such as health maintenance organizations, or HMOs, and managed care organizations, or MCOs. Third party payors increasingly challenge pharmaceutical product pricing. The trend toward managed healthcare in the United States, the growth of organizations such as HMOs and MCOs, and various legislative proposals and enactments to reform healthcare and government insurance programs, including the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, could significantly influence the manner in which pharmaceutical products are prescribed and purchased, which could result in lower prices and/or a reduction in demand for Allergan’s products.
      In a recent rule establishing a competitive acquisition program, beginning January 2006, physicians who administer drugs in their offices will be offered an option to acquire drugs covered under the Medicare Part B benefit from vendors who are selected in a competitive bidding process. Winning vendors would be selected based on criteria that include their bid price. Such cost containment measures and healthcare reforms could adversely affect Allergan’s ability to sell its products. Furthermore, individual states have become increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access, importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third party payors or other restrictions could negatively and materially impact Allergan’s revenues and financial condition. Allergan encounters similar regulatory and legislative issues in most countries outside the United States. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in the prescription drug and other healthcare programs. This can reduce demand for Allergan’s products or put pressure on its product pricing, which could negatively affect its revenues and profitability.
Allergan is subject to risks arising from currency exchange rates, which could increase its costs and may cause its profitability to decline.
      Allergan collects and pays a substantial portion of its sales and expenditures in currencies other than the U.S. dollar. Therefore, fluctuations in foreign currency exchange rates affect its operating results. There can be no assurance that future exchange rate movements, inflation or other related factors will not have a material adverse effect on Allergan’s sales, gross profit or operating expenses.
Allergan is subject to risks associated with doing business internationally.
      Allergan’s business is subject to certain risks inherent in international business, many of which are beyond its control. These risks include, among other things:
  adverse changes in tariff and trade protection measures;
 
  unexpected changes in foreign regulatory requirements;
 
  potentially negative consequences from changes in or interpretations of tax laws;
 
  differing labor regulations;
 
  changing economic conditions in countries where Allergan’s products are sold or manufactured or in other countries;
 
  differing local product preferences and product requirements;
 
  exchange rate risks;
 
  restrictions on the repatriation of funds;

20


Table of Contents

  political unrest and hostilities;
 
  differing degrees of protection for intellectual property; and
 
  difficulties in coordinating and managing foreign operations.
      Any of these factors, or any other international factors, could have a material adverse effect on Allergan’s business, financial condition and results of operations. There can be no assurance that Allergan can successfully manage these risks or avoid their effects.
Allergan may be subject to intellectual property litigation and infringement claims, which could cause it to incur significant expenses and losses or prevent it from selling its products.
      Although Allergan has a corporate policy not to infringe the valid and enforceable patents of others, there can be no assurance that Allergan’s products will not infringe patents held by third parties. If Allergan or a third party discovers that Allergan may be infringing third party patents, licenses from those third parties may not be available on commercially attractive terms or at all. Allergan may have to defend, and has recently defended, against allegations that it violated patents or the proprietary rights of third parties. Litigation is costly and time-consuming, and diverts the attention of management and technical personnel. In addition, if Allergan infringes the intellectual property rights of others, it could lose its right to develop, manufacture or sell products or could be required to pay monetary damages or royalties to license proprietary rights from third parties. An adverse determination in a judicial or administrative proceeding or a failure to obtain necessary licenses could prevent Allergan from manufacturing or selling its products, which could harm its business, financial condition, prospects, results of operations and cash flows. See Item 1 of Part II of Allergan’s Form 10-Q for the quarter ended September 30, 2005, and Note 9 in the notes to the unaudited condensed consolidated financial statements contained therein for information concerning Allergan’s current intellectual property litigation.
The consolidation of drug wholesalers and other wholesaler actions could increase competitive and pricing pressures on pharmaceutical manufacturers, including Allergan.
      Allergan sells its pharmaceutical products primarily through wholesalers. These wholesale customers comprise a significant part of the distribution network for pharmaceutical products in the United States. This distribution network is continuing to undergo significant consolidation marked by mergers and acquisitions. As a result, a smaller number of large wholesale distributors control a significant share of the market. Allergan expects that consolidation of drug wholesalers will increase competitive and pricing pressures on pharmaceutical manufacturers, including Allergan. In addition, wholesalers may apply pricing pressure through the implementation of fee-for-service arrangements, and their purchases may exceed customer demand, resulting in reduced wholesaler purchases in later quarters. There can be no assurance that Allergan can manage these pressures or that wholesaler purchases will not decrease as a result of this potential excess buying.
Allergan may acquire other companies in the future and these acquisitions could disrupt its business.
      As part of its business strategy, Allergan regularly considers and, as appropriate, makes acquisitions of technologies, products and businesses that it believes are complementary or additive to its business. As discussed above, acquisitions typically entail many risks and could result in difficulties in integrating the operations, personnel, technologies and products of the companies acquired, some of which may result in significant charges to earnings. If Allergan is unable to successfully integrate these acquisitions with its existing business, it may not obtain the advantages that the acquisitions were intended to create, which may materially adversely affect its business, results of operations, financial condition and cash flows, its ability to develop and introduce new products and the market price of its stock. In connection with acquisitions, Allergan could experience disruption in its business or employee base, or key employees of companies that it acquires may seek employment elsewhere, including with Allergan’s competitors. Furthermore, the products of companies Allergan acquires may overlap with its products or those of its customers, creating conflicts with existing relationships or with other commitments that are detrimental to the integrated businesses.

Compliance with the extensive government regulations to which Allergan is subject is expensive and time consuming, and may result in the delay or cancellation of product sales, introductions or modifications.
      Extensive industry regulation has had, and will continue to have, a significant impact on Allergan’s business, especially its product development and manufacturing capabilities. All pharmaceutical companies, including Allergan, are subject to extensive, complex, costly and evolving regulation by federal governmental authorities, principally by the FDA and the U.S. Drug Enforcement Administration, or DEA, and similar foreign and state government agencies. Failure to comply with the regulatory requirements of the FDA, DEA and other U.S. and foreign regulatory requirements may subject a company to administrative or judicially imposed sanctions, including, among others, a refusal to approve a pending application to market a new product or a new indication for an existing product. The Federal Food, Drug, and Cosmetic Act, the Controlled Substances Act and other domestic and foreign statutes and regulations govern or influence the research, testing, manufacturing, packing, labeling, storing, record keeping, safety, effectiveness, approval, advertising, promotion, sale and distribution of Allergan’s products. Under certain of these regulations, Allergan is subject to periodic inspection of its facilities, production processes and control operations and/or the testing of its products by the FDA, the DEA and other authorities, to confirm that they are in compliance with all applicable regulations, including the FDA’s cGMP regulations. The FDA conducts pre-approval and post-approval reviews and plant inspections of Allergan and its suppliers to determine whether its record keeping, production processes and controls, personnel and quality control are in compliance with the cGMPs and other FDA regulations. Allergan is also required to perform extensive audits of its vendors, contract laboratories and suppliers to ensure that they are compliant with these requirements. In addition, in order to commercialize its products or new indications for an existing product, Allergan must demonstrate that the product or new indication is safe and effective, and that its and its suppliers’ manufacturing facilities are compliant with applicable regulations, to the satisfaction of the FDA and other regulatory agencies.
      The process for obtaining governmental approval to manufacture pharmaceutical products is rigorous, typically takes many years and is costly, and Allergan cannot predict the extent to which it may be affected by legislative and regulatory developments. Allergan is dependent on receiving FDA and other governmental approvals prior to manufacturing, marketing and shipping its products. Allergan may fail to obtain approval from the FDA or other governmental authorities for its product candidates, or experience delays in obtaining such approvals, due to varying interpretations of data or failure to satisfy rigorous efficacy, safety and manufacturing quality standards. Consequently, there is always a risk that the FDA or other applicable governmental authorities will not approve Allergan’s products, or will take post-approval action limiting or revoking Allergan’s ability to sell its products, or that the rate, timing and cost of such approvals will adversely affect Allergan’s product introduction plans, results of operations and stock price. Despite the time and expense exerted, regulatory approval is never guaranteed.
      Even after Allergan obtains regulatory approval for a product candidate or new indication, it is subject to extensive regulation, including ongoing compliance with the FDA’s cGMP regulations, completion of post-marketing clinical studies mandated by the FDA, and compliance with regulations relating to adverse event reporting, labeling, advertising, marketing and promotion. If Allergan or any third party that it involves in the testing, packing, manufacture, labeling, marketing and distribution of its products fails to comply with any such regulations, they may be subject to, among other things, warning letters, product seizures, recalls, fines or other civil penalties, injunctions, suspension or revocation of approvals, operating restrictions and criminal prosecution.
      The FDA recently has increased its enforcement activities related to the advertising and promotion of pharmaceutical and biological products. In particular, the FDA has expressed concern regarding the pharmaceutical industry’s compliance with the agency’s regulations governing direct-to-consumer advertising, and has increased its scrutiny of such promotional materials. The FDA may limit or, with respect to certain products, terminate Allergan’s dissemination of direct-to-consumer advertisements in the future, which could cause sales for those products to decline.
      Physicians may prescribe pharmaceutical or biologic products for uses that are not described in a product’s labeling or differ from those tested by Allergan and approved by the FDA. While such “off-label”

22


Table of Contents

uses are common and the FDA does not regulate a physician’s choice of treatment, the FDA does restrict a manufacturer’s communications on the subject of off-label use. Companies cannot actively promote FDA-approved pharmaceutical or biologic products for off-label uses, but they may disseminate to physicians articles published in peer-reviewed journals. To the extent allowed by law, Allergan disseminates peer-reviewed articles on its products to targeted physicians. If, however, its promotional activities fail to comply with the FDA’s regulations or guidelines, it may be subject to warnings from, or enforcement action by, the FDA or another enforcement agency.
If Allergan markets products in a manner that violates health care fraud and abuse laws, it may be subject to civil or criminal penalties.
      Federal health care program anti-kickback statutes prohibit, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce or in return for purchasing, leasing, ordering, or arranging for the purchase, lease or order of any health care item or service reimbursable under Medicare, Medicaid, or other federally financed health care programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchases, or recommendations may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Although Allergan believes that it is in compliance, its practices may be determined to fail to meet all of the criteria for safe harbor protection from anti-kickback liability.
      Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to get a false claim paid. Pharmaceutical companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities, such as allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion that caused claims to be submitted to Medicaid for non-covered off-label uses; and submitting inflated best price information to the Medicaid Rebate Program.
      The majority of states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. Sanctions under these federal and state laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs, criminal fines, and imprisonment.
      Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of Allergan’s business activities could be subject to challenge under one or more of such laws. For example, Allergan and several other pharmaceutical companies are currently subject to suits by governmental entities in several jurisdictions, including Massachusetts, New York and Alabama alleging that Allergan and those other companies, through promotional, discounting, and pricing practices reported false and inflated average wholesale prices or wholesale acquisition costs and failed to report best prices as required by federal and state rebate statutes, resulting in the plaintiffs overpaying for certain medications.

COMPARATIVE PER SHARE DATA
(UNAUDITED)
      The following table reflects historical information about basic and diluted income per share, cash dividends per share, and book value per share for the nine month period ended September 30, 2005 and the year ended December 31, 2004, on a historical basis, and for Allergan and Inamed on an unaudited pro forma combined basis after giving effect to the Offer, the Inamed Merger and the Post-Closing Merger. The pro forma data of the combined company assumes the acquisition of 100% of the Inamed Shares by Allergan and was derived by combining the historical consolidated financial information of Allergan and Inamed as described elsewhere in this prospectus. The equivalent pro forma combined per share data for Allergan assumes that 45% of the Inamed Shares will be exchanged for cash and 55% of the Inamed Shares will be exchanged for shares of Allergan common stock. The actual percentage of cash and Allergan common stock an Inamed stockholder will receive depends upon such stockholder’s election and the elections made by other Inamed stockholders and any resulting proration. For a discussion of the assumptions and adjustments made in preparing the pro forma financial information presented in this prospectus, see “Unaudited Pro Forma Combined Condensed Financial Statements.”
      Inamed stockholders should read the information presented in the following table together with the historical financial statements of Allergan and Inamed and the related notes which are incorporated herein by reference, and the “Unaudited Pro Forma Combined Condensed Financial Statements” appearing elsewhere in this prospectus. The pro forma data is unaudited and for illustrative purposes only. Inamed stockholders should not rely on this information as being indicative of the historical results that would have been achieved during the periods presented had the companies always been combined or the future results that the combined company will achieve after the consummation of the Offer, the Inamed Merger and the Post-Closing Merger. This pro forma information is subject to risks and uncertainties, including those discussed under “Risk Factors” above.

REASONS FOR THE OFFER
      Allergan believes that the proposed acquisition of Inamed by Offeror and Allergan will produce the following benefits:
  Increased Market Presence and Opportunities. The combination of Allergan and Inamed would increase the combined company’s market presence and opportunities for growth in sales, earnings and stockholder returns.

BACKGROUND OF THE OFFER
Allergan Proposal
      As part of the continuous evaluation of its businesses and the industry in which it competes, Allergan regularly considers a variety of strategic options and transactions that complement its strategic focus or provide growth opportunities in its current markets. Recently, Allergan has consulted with its financial advisers and reviewed various strategic alternatives that provide opportunities for growth in the aesthetics market, including the proposed Offer and Inamed Merger.
      On November 14, 2005, Allergan sent a letter to Inamed setting forth a proposal for a business combination between Inamed and Allergan. On November 15, 2005, Allergan issued a press release, which attached a copy of the letter.
The full text of the Allergan letter is as follows:
      November 14, 2005
  Mr. Nicholas L. Teti
  Chairman, President and Chief Executive Officer
  Inamed Corporation
  5540 Ekwill Street
  Santa Barbara, CA 93111
 
  Dear Mr. Teti:
  We are pleased to submit a proposal to acquire Inamed in a transaction that will provide your stockholders substantially greater value than your pending merger with Medicis.
  We are proposing to acquire all of Inamed’s outstanding shares in a transaction providing Inamed stockholders with a per share consideration of $84.00 in cash or 0.8498 of a share of Allergan common stock. We will provide the opportunity for each Inamed stockholder to elect whether to receive the consideration in cash or common stock of Allergan, subject to the limitation that the total value of the consideration payable will be $1.45 billion in cash and 17.9 million shares of Allergan.
 
  Our proposal is clearly superior to Medicis’, both financially and strategically:
      (i)  It will provide the immediate opportunity for your stockholders to realize substantially greater value for their shares—a 12% premium over the initial Medicis offer and a 16% premium over the currently implied Medicis offer.
      (ii)  It offers greater certainty of value for Inamed’s stockholders as it includes 26% more cash and shares that are more liquid.
     (iii)  It offers closure at least as fast as or faster than the Medicis transaction.
     (iv)  Your stockholders will have the opportunity to realize greater long-term value as a result of the truly unique attributes of an Allergan-Inamed combination, which will create a global leader in medical aesthetics, creating value for both companies’ stockholders, employees, patients and customers.
  This transaction also will result in the combination of two strong companies and will afford the opportunity to mutually enhance our skills. We have great respect for Inamed and are confident that we will be able to integrate the two companies to build a stronger, more efficient company. Additionally, employees of both companies will benefit from the greater resources and opportunities that come from being part of a larger organization.
 
  We are aware that Medicis’ proposed merger with Inamed has prompted a lengthy and still-ongoing antitrust investigation by the Federal Trade Commission, which could continue to cause substantial delays in the completion of that transaction. Allergan does not envision any such problems with its proposed acquisition of Inamed. We are confident that there will be no material delay in the transaction

36


Table of Contents

  we are proposing on account of Federal Trade Commission review. In order to minimize any potential antitrust issues, Allergan will agree to an immediate divestiture of Inamed’s license to Reloxin®. And if and to the extent needed, Allergan will seek cooperation from Beaufour Ipsen Ltd. in this regard. Allergan will also cooperate fully with any subsequent licensee of Reloxin® to ensure that the new licensee is able to benefit from studies or other work that Inamed has done in an effort to obtain regulatory approvals from the U.S. Food and Drug Administration or other regulatory agencies. We have been advised by counsel that, in contrast to Inamed’s proposed merger with Medicis, an acquisition of Inamed by Allergan, with an agreed upon divestiture of any rights to Reloxin®, should not result in any prolonged investigation by U.S. or foreign antitrust authorities. However, to ensure that all necessary antitrust approvals are obtained as expeditiously as possible, Allergan intends to file its Hart-Scott-Rodino pre-merger notification no later than November 15, 2005, and any additional foreign filings that may be required will be made promptly thereafter.
 
  Our proposal represents a “Company Superior Proposal” that clearly meets the standards set forth in Section 8.03 of the existing merger agreement. It offers greater value to Inamed stockholders and has greater certainty of completion than the pending merger. We can comfortably fund the cash portion of the consideration through a combination of cash on hand and permanent financing and have sufficient authorized and unissued shares for the acquisition. Further, no vote of Allergan stockholders will be required for the issuance of Allergan’s stock in the transaction. As a result, our transaction can be completed in a timely manner with a goal of closing the acquisition in January 2006 and involves no delay in comparison with the proposed merger with Medicis.
 
  Our proposal is subject to the execution of a mutually acceptable definitive agreement and the satisfactory completion of limited due diligence to confirm (i) that there are no material undisclosed adverse facts or developments concerning Inamed or it products or pipeline (including, but not limited to, material facts regarding the development and regulatory approval process and timeline for Juvéderm® in the United States) that have not been publicly disclosed; and (ii) that neither Inamed’s license from Corneal Group for the rights to develop, distribute and market the Juvéderm® dermal fillers nor the “approvable letter” from the Food and Drug Administration announced September 21, 2005 for certain breast implants (nor any correspondence relating thereto) contain any terms and conditions not publicly disclosed that would materially adversely affect the value of Inamed’s acquisition to Allergan and its stockholders. We, our legal advisor, Gibson, Dunn & Crutcher, and our financial advisor, Morgan Stanley, are ready to proceed with the due diligence review immediately, and Allergan’s executed confidentiality agreement is enclosed herewith. We are prepared to enter into a merger agreement consistent with the terms set forth herein and otherwise substantially the same as your existing merger agreement with Medicis. Of course, we are prepared to afford you and your representatives access to non-public information concerning Allergan for the purpose of your due diligence review.
 
  The Allergan Board supports the combination of our companies. We trust you and Inamed’s other directors will respond immediately and positively to our proposal. We look forward to working with you to achieve what will be a compelling transaction for the stockholders, customers, partners and employees of our two companies.
  Very truly yours,
 
  /s/ David E.I. Pyott
 
 
  David E.I. Pyott
  Chairman of the Board, President and
  Chief Executive Officer

Table of Contents

        On November 16, 2005, Inamed announced that its Board of Directors, after conferring with the company’s legal and financial advisors, had determined that the Allergan proposal is reasonably likely to result in a “Company Superior Proposal” as the term was used in the Medicis merger agreement, and directed Inamed’s management to evaluate the Allergan proposal. Following the execution of a mutual confidentiality agreement between Allergan and Inamed, a meeting was held November 18, 2005 between representatives of the two companies to discuss the proposed transaction and procedures for the exchange of non-public information for due diligence purposes. The two companies began making arrangements for the exchange of information promptly thereafter.
      On November 22, 2005, the companies and their representatives commenced mutual due diligence and on December 1, 2005, a meeting was held between representatives of the two companies to present to each other an overview of each of the companies.
      Beginning the week of November 27, 2005, the companies and their representatives commenced negotiating certain revised terms and conditions to the offer and merger pursuant to which Allergan would acquire Inamed. On December 5, 2005, the filing deadline for Inamed’s Solicitation/ Recommendation Statement on Schedule 14D-9, the companies had not completed their negotiation of the revised terms and conditions, and thus the Inamed board of directors voted unanimously to recommend that the Inamed stockholders reject the Offer. However, on December 5, 2005, the companies continued to actively negotiate the terms and conditions of a definitive agreement.
      On December 6, 2005, the companies reached agreement on the terms of the Allergan Merger Agreement, and Allergan executed and delivered to Inamed an irrevocable offer letter accompanied by an executed copy of the definitive Allergan Merger Agreement. Under the terms of the Medicis merger agreement, prior to the termination of the Medicis merger agreement, Inamed could not enter into the Allergan Merger Agreement. However, Allergan’s irrevocable offer letter provided that Inamed could accept the offer set forth in the offer letter at any time after the Medicis merger agreement was terminated and after receipt of notice from Allergan that the conditions to the irrevocable offer had been met. Unless previously accepted by Inamed in a manner that did not constitute a breach of the Medicis merger agreement, the irrevocable offer by its terms would automatically expire and be of no further force and effect upon the occurrence of any of the events specified in the irrevocable offer letter.
      The text of the irrevocable offer letter is as follows:
  December 5, 2005
 
  Mr. Nicholas L. Teti
  Chairman, President and Chief Executive Officer
  Inamed Corporation
  5540 Ekwill Street
  Santa Barbara, CA 93111
Dear Mr. Teti:
        We are pleased to provide you with the attached Agreement and Plan of Merger (the “Merger Agreement”) among Allergan, Inc. (“Allergan”), Banner Acquisition, Inc. (“Merger Sub”) and Inamed Corporation (“Inamed”) executed by Allergan and Merger Sub. The execution and delivery of the Merger Agreement by Allergan and Merger Sub in conjunction with this letter constitutes a binding irrevocable offer (subject only to the terms and conditions set forth herein) by Allergan and Merger Sub to Inamed to enter into the Merger Agreement, and to conduct an exchange offer by Merger Sub for all of the shares of Inamed common stock on the terms and conditions set forth in the Merger Agreement (the “Offer”) and promptly thereafter to consummate the second step merger contemplated thereby (the “Merger”). Inamed can accept this irrevocable offer at any time, after receipt of notice from Allergan that the conditions to this irrevocable offer set forth below have been met, by executing the Merger Agreement and returning the executed copy to me prior to the expiration thereof as set forth in this letter.

38


Table of Contents

        This irrevocable offer is subject solely to the following conditions:
 
        (1) Allergan shall be satisfied with the results of its limited due diligence investigation of Juvéderm®, which will be conducted solely to confirm that there are no material undisclosed adverse facts or developments, including, but not limited to, material facts regarding the development and regulatory approval process and timeline for Juvéderm® in the United States, and
 
        (2) Allergan shall be reasonably satisfied that there are no material facts or circumstances contained in Inamed schedules to the Merger Agreement that have not been disclosed to Allergan prior to the date hereof.
 
        If, in Allergan’s reasonable judgment, the foregoing conditions are not met, this irrevocable offer may not be accepted by Inamed, and shall automatically expire and be of no further force or effect. After expiration of this irrevocable offer, Allergan and Merger Sub shall have no further liability or obligation to Inamed, notwithstanding the execution and delivery of the Merger Agreement or this letter.
 
        In addition, unless previously accepted by Inamed, in a manner that does not constitute a breach of the Medicis merger agreement, this irrevocable offer shall automatically expire and be of no further force and effect on the earliest to occur of the following events:
        (1) At 5:00 pm. Pacific Standard Time on December 6, 2005, unless at or prior to such time Inamed:
  •  has determined that the Offer constitutes a Company Superior Proposal within the meaning of the Medicis merger agreement;
 
  •  has determined in good faith, after consultation with outside legal counsel, that failure to (i) withdraw the recommendation of the Medicis merger agreement, and (ii) approve and recommend the Offer, would reasonably be likely to constitute a violation of its fiduciary duties under applicable law; and
 
  •  has delivered written notice of such determinations to Medicis.
        If Inamed timely takes these actions, then within five business days after delivery of the written notice to Medicis referenced in the third bullet above, Allergan and Merger Sub, as applicable, shall amend the registration statement on Form S-4 and the Schedule TO relating to Merger Sub’s exchange offer for of the outstanding shares of Inamed common stock commenced on November 21, 2005, to disclose the terms of this irrevocable offer and to state that the terms and conditions of such exchange offer will be amended to conform to the terms and conditions of the Offer upon acceptance of this irrevocable offer by Inamed in accordance with the terms and conditions set forth herein and Inamed’s execution and delivery of the Merger Agreement.
 
        (2) At 5:00 pm. Pacific Standard Time on December 13, 2005, unless on or prior to such time, Inamed has:
  •  publicly withdrawn its recommendation of the Medicis merger agreement,
 
  •  approved and publicly recommended the Offer; and
 
  •  amended its Solicitation/ Recommendation Statement on Schedule 14D-9 with respect to Merger Sub’s exchange offer for all of the outstanding shares of Inamed common stock commenced on November 21, 2005 (the “14D-9”) to reflect the foregoing.
        (3) 48 hours following termination of the Medicis merger agreement if:
  •  Inamed has failed to provide, prior to such time, (A) all information requested by Allergan to enable Allergan to complete its limited due diligence investigation concerning Juvederm described above, and (B) Inamed’s definitive disclosure schedules to the Merger Agreement, or

39


Table of Contents

  •  the Inamed board of directors has failed, prior to such time, to (A) approve the Merger Agreement and authorize the officers of Inamed to execute the Merger Agreement upon receipt of notice from Allergan that Allergan is satisfied that the conditions set forth above have been met, (B) approve the Offer and the Merger such that Section 203 of the Delaware General Corporation Law shall not apply to such transactions and approve the amendment of the Inamed stockholder rights agreement to provide that the stockholder rights agreement shall not apply to the Offer and the Merger, and (C) provided copies of such authorizations to Allergan (which authorizations shall be satisfactory to Allergan in its reasonable judgment).
        (4) 24 hours following delivery by Allergan of written notice to Inamed that Allergan is satisfied with its limited due diligence investigation of Juvederm and Inamed’s definitive disclosure schedules to the Merger Agreement, each as described above, unless Inamed has executed and delivered to Allergan the Merger Agreement.
 
        (5) At 5:00 p.m. Pacific Standard Time on December 31, 2005.
 
        We believe we have addressed all of the concerns we understood the Board of Directors of Inamed had with the terms of the exchange offer commenced by Merger Sub on November 21, 2005.
 
        We look forward to hearing from you with regard to your determination.
  Very truly yours,
 
  /s/ Douglas S. Ingram

  Executive Vice President,
  General Counsel and Secretary
      The terms and conditions of the Allergan Merger Agreement attached to the irrevocable offer letter are described below under “Allergan Merger Agreement,” and a copy of the Allergan Merger Agreement is attached as Annex A hereto.
      After receipt of the irrevocable offer letter and the Allergan Merger Agreement executed by Allergan, Inamed issued a press release on December 6, 2005 and filed an amendment to its Schedule 14D-9, announcing that its board of directors has determined that the Allergan Merger Agreement and the offer set forth therein are fair to Inamed’s stockholders and constitute a “Company Superior Proposal” (as such term was defined in the Medicis merger agreement) when compared to the Medicis merger agreement.
Termination of the Medicis Merger Agreement
      As noted above, on December 13, 2005, Inamed and Medicis each announced the termination of the Medicis merger agreement pursuant to a Merger Termination Agreement, which agreement provided that the Medicis merger agreement would be terminated effective upon the execution of the Merger Termination Agreement and Medicis’ receipt from Inamed of a termination fee of $90,000,000 and reimbursement of $481,985 with respect to certain Medicis expenses. The Merger Termination Agreement also provides for a mutual release of certain claims in connection with the termination of the Medicis merger agreement.
      According to public filings made by Inamed and Medicis with the SEC on December 13, 2005, the termination fee and expense reimbursement payments were paid in full by Inamed on December 13, 2005 and the Medicis merger agreement was terminated in its entirety at such time. In connection with such termination, Inamed announced the cancellation of the special meeting of Inamed stockholders scheduled for December 19, 2005.

Recommendation of the Inamed Board
      On December 13, 2005, Inamed filed an amendment to its Solicitation/ Recommendation Statement on Schedule 14D-9 initially filed with the SEC on December 5, 2005 and subsequently amended. That amendment disclosed that on December 13, 2005 Inamed’s board of directors determined that the terms of the exchange offer set forth in the Allergan Merger Agreement and the Allergan Merger Agreement are advisable, fair to and in the best interests of the Inamed stockholders, and resolved to recommend that the Inamed stockholders tender their Inamed Shares pursuant to the Offer upon Inamed’s execution of the Allergan Merger Agreement and the amendment of the Offer to conform to the terms of the exchange offer set forth in the Allergan Merger Agreement.
      At meetings held on December 13 and 14, 2005, Inamed’s board of directors:
  •  formally and unanimously approved and adopted the terms of the Allergan Merger Agreement;
 
  •  approved the Offer, the Inamed Merger and the Post-Closing Merger such that Section 203 of the Delaware General Corporation Law would not apply to such transactions;
 
  •  approved the amendment of Inamed’s stockholder rights agreement to provide that the execution of the Allergan Merger Agreement and the consummation of the transactions contemplated by the Allergan Merger Agreement would not trigger the rights plan; and
 
  •  resolved to recommend that Inamed Shareholders tender their shares pursuant to the offer contemplated by the Allergan Merger Agreement.
Execution of the Allergan Merger Agreement

Promptly following the receipt of such written notice, Inamed executed and delivered the Allergan Merger Agreement to Allergan.

ALLERGAN MERGER AGREEMENT
      The following summary describes certain material provisions of the definitive merger agreement entered into by Allergan, Offeror and Inamed, a copy of which is attached as Annex A hereto and incorporated herein by reference. This summary may not contain all of the information about the Allergan Merger Agreement that is important to Inamed stockholders, and Inamed stockholders are encouraged to read the Allergan Merger Agreement carefully in its entirety. The legal rights and obligations of the parties are governed by the specific language of the Allergan Merger Agreement, and not this summary.
The Offer
      The Allergan Merger Agreement provides for the making of the Offer. Under the Allergan Merger Agreement, the obligation of Offeror to accept for exchange and to exchange Inamed Shares for cash and shares of Allergan common stock tendered pursuant to the Offer is subject to the satisfaction of certain conditions. These conditions are described under “The Offer — Conditions of the Offer” below.
      Under the Allergan Merger Agreement, Offeror:
  •  shall extend the Offer from time to time in increments of no more than 10 business days each, if at the initial or any subsequent scheduled expiration date any of the conditions of the Offer have not been satisfied or waived;
 
  •  shall extend the Offer for any period required by any rule, regulation or interpretation of the SEC applicable to the Offer; and
 
  •  may extend the Offer one time for up to five business days if less than 90% of the Inamed Shares on a fully diluted basis have not been validly tendered at the scheduled expiration date.
The Inamed Merger
      The Allergan Merger Agreement provides for the merger of Offeror with and into Inamed. As a result of the Inamed Merger, Offeror will cease to exist and Inamed will continue as the corporation surviving the Inamed Merger. After the Inamed Merger, the Surviving Corporation will be a wholly owned subsidiary of Allergan and the former Inamed stockholders will not have any equity ownership interest in the Surviving Corporation.
The Post-Closing Merger
      As promptly as practicable after the Inamed Merger, Allergan intends to cause the Surviving Corporation to merge with and into a wholly owned limited liability company subsidiary of Allergan. Immediately before the Post-Closing Merger, Allergan will be the sole stockholder of the Surviving Corporation, and none of the former Inamed stockholders will have any economic interest in, or approval or other rights with respect to, the Post-Closing Merger.
Completion and Effectiveness of the Inamed Merger
      The closing of the Inamed Merger will occur on the second business day after all of the conditions to completion of the Inamed Merger contained in the Allergan Merger Agreement, including the condition that the Offer shall have been completed, are satisfied or waived, unless the parties agree otherwise in writing (see “—Conditions to Completion of the Merger” below). The Inamed Merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware.
Merger Consideration
General
      Upon completion of the Inamed Merger, each Inamed Share outstanding immediately prior to the effective time of the Inamed Merger will be cancelled and extinguished and converted into the right to receive,

Table of Contents

at the election of the holder (a) $84.00 in cash, without interest, or (b) 0.8498 of a share of Allergan common stock (including the associated preferred stock purchase rights), in each case subject to proration. This consideration will be paid upon surrender of the stock certificate formerly representing the cancelled Inamed Shares in the manner provided in the Allergan Merger Agreement. Any holder of Inamed Shares who has not submitted a letter of election and transmittal within 30 days after the letters of election and transmittal are sent to former Inamed stockholders, will be deemed to have made no election. Inamed Shares held by stockholders who validly exercise and perfect appraisal rights will be subject to appraisal in accordance with Delaware law as described further below under “—Appraisal Rights.”
      The maximum aggregate amount of cash payable pursuant to the Inamed Merger will be:
  $84.00 multiplied by 45% of the total number of Inamed Shares canceled pursuant to the Inamed Merger, minus the cash value of any shares held by Inamed stockholders who validly exercise appraisal rights (this amount is sometimes referred to as the “maximum cash merger consideration”).
      The maximum aggregate number of shares of Allergan common stock payable pursuant to the Inamed Merger shall be:
  0.8498 of a share of Allergan common stock multiplied by 55% of the total number of Inamed Shares canceled pursuant to the Inamed Merger (this amount is sometimes referred to as the “maximum stock merger consideration”).
      The stock merger consideration, together with the cash merger consideration, is sometimes referred to in this prospectus as the “merger consideration.” The percentages of cash and stock consideration issued pursuant to the Inamed Merger also may be subject to adjustments to the extent necessary to protect the treatment of the Offer, the Inamed Merger and the Post-Closing Merger, collectively, as a reorganization under Section 368(a) of the Code, as provided in the Allergan Merger Agreement.
      Upon completion of the Inamed Merger, each Inamed Share held by Allergan or any direct or indirect wholly-owned subsidiaries of Allergan, including Offeror, immediately prior to the Inamed Merger will be automatically cancelled and extinguished, without consideration.
Appraisal Rights
      Although Inamed Stockholders do not have appraisal rights in connection with the Offer, Inamed Shares held by Inamed stockholders who properly demand payment for such shares in compliance with Section 262 of the DGCL will not be converted into the right to receive the merger consideration, but instead will be converted into the right to receive such consideration as may be determined to be due to such stockholder pursuant to Section 262 of the DGCL. However, if any Inamed stockholder fails to perfect or otherwise waives, withdraws or loses the right to receive payment under Section 262, then that Inamed stockholder will not be paid in accordance with Section 262 and the Inamed Shares held by that Inamed stockholder will be exchangeable solely for the right to receive the merger consideration as set forth in the Allergan Merger Agreement.
Exchange of Inamed Stock Certificates for the Merger Consideration
      Allergan has retained Wells Fargo Bank, N.A. as the depositary and exchange agent for the Inamed Merger to handle the exchange of Inamed Shares for the merger consideration. Wells Fargo also will effect any sales of fractional shares in the public markets and will pay the proceeds of such sales to the stockholders on whose behalf such fractional shares are sold, as provided in the Allergan Merger Agreement.
      After the effective time of the Inamed Merger, each stock certificate formerly representing Inamed Shares that has not been surrendered will represent only the right to receive upon such surrender the merger consideration to which such holder is entitled by virtue of the Inamed Merger and any dividends or other distributions payable to such holder upon such surrender. From and after the effective time of the Inamed Merger, Inamed will not register any transfers of Inamed Shares that were outstanding on its stock transfer books prior to the Inamed Merger.

43


Table of Contents

      To effect the exchange of Inamed Shares, as soon as reasonably practicable after the effective time of the Inamed Merger, the exchange agent will mail to each record holder of Inamed Shares a letter of election and transmittal and instructions for surrendering the stock certificates that formerly represented Inamed Shares for the merger consideration. After surrender to the exchange agent of certificates that formerly represented Inamed Shares for cancellation, together with an executed letter of election and transmittal, the record holder of the surrendered certificates will be entitled to receive the merger consideration.
Fractional Shares
      Allergan will not issue fractional shares of Allergan common stock in the Inamed Merger. Instead, each holder of Inamed Shares who otherwise would be entitled to receive fractional shares of Allergan common stock in the Inamed Merger will be entitled to an amount of cash (without interest) equal to such holders’ respective proportionate share of the proceeds from the sale of the aggregate fractional shares of Allergan common stock issued pursuant to the Inamed Merger made in the open market by the exchange agent on behalf of all such holders.
Top-Up Option
      Subject to certain terms and conditions in the Allergan Merger Agreement, Offeror has an irrevocable option to purchase up to that number of Inamed Shares equal to the lowest number of Inamed Shares that, when added to the number of Inamed Shares collectively owned by Allergan, Offeror and any of Allergan’s other subsidiaries immediately following consummation of the Offer, shall constitute 90% of the Inamed Shares then outstanding (on a fully diluted basis, after giving effect to any exercise of the “Top-Up” option) at a purchase price per Inamed Share of $84.00. The purchase price may be paid in cash, shares of Allergan common stock, a promissory note, or a combination thereof.
      The Top-Up option may not be exercised if the aggregate number of Inamed Shares issuable upon exercise of the Top-Up option, plus the aggregate number of then-outstanding Inamed Shares, plus the aggregate number of Inamed Shares issuable upon exercise of all options and other rights to purchase Inamed Shares, plus the aggregate number of shares reserved for issuance pursuant to Inamed’s stock plans, would exceed the number of then-authorized Inamed Shares.
Conditions to Completion of the Offer
      Pursuant to the terms of the Allergan Merger Agreement, Offeror is not required to accept for exchange or exchange any Inamed Shares and may postpone the acceptance for exchange of or exchange of, tendered Inamed Shares, if at the time of the scheduled expiration date of the Offer certain conditions are not met, and Offeror may, in its reasonable discretion (but subject to the requirements of applicable laws) terminate or amend the Offer in accordance with the Allergan Merger Agreement if, certain conditions are not met. These conditions to the Offer are set forth in “The Offer—Conditions of the Offer” below.
Conditions to the Inamed Merger
      In addition to the completion of the Offer, the respective obligations of Inamed, Allergan and Offeror to complete the Inamed Merger under the Allergan Merger Agreement are subject to the satisfaction of the following conditions:
    if required by the DGCL, the Allergan Merger Agreement will have been adopted by the stockholders of Inamed in accordance with the DGCL;
 
    no judgment, injunction, order or decree of a governmental entity of competent jurisdiction will be in effect that has the effect of making the Inamed Merger or the Post-Closing Merger illegal or otherwise restraining or prohibiting the consummation of the Inamed Merger or the Post-Closing Merger;
 
    all consents, approvals, orders or authorizations from, and all material declarations, filings and registrations with, any governmental entity required to consummate the Inamed Merger and the Post-

44


Table of Contents

  Closing Merger will have been obtained or made, except for such consents, approvals, orders, authorizations, material declarations, filings and registrations, the failure of which to be obtained or made would not, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect (for purposes of this clause, after giving effect to the Inamed Merger);
 
    no stop order suspending the effectiveness of the registration statement will be in effect and no proceedings for such purpose will be pending before the SEC; and
 
  Offeror will have exchanged Inamed Shares pursuant to the Offer (provided that this will not be a condition to Allergan’s and Offeror’s obligations if Offeror has failed to exchange the Inamed Shares in violation of the Allergan Merger Agreement).
Representations and Warranties
      The Allergan Merger Agreement contains customary representations and warranties of the parties. These include representations and warranties of Inamed with respect to: corporate organization and qualification; capitalization; subsidiaries; authority; SEC filings and financial statements; absence of undisclosed liabilities; litigation; absence of certain changes or events; compliance with laws and permits; material contracts and defaults; taxes; employee benefit plans; labor and employment matters; environmental matters; intellectual property; real property; regulatory compliance; insurance matters; opinion of financial advisors; brokers and finders; and foreign corrupt practices and international trade sanctions. The Allergan Merger Agreement also contains additional representations of Inamed related to the amendment of the Inamed rights agreement. The Allergan Merger Agreement also contains customary representations and warranties of Allergan and Offeror, including among other things: organization and qualification; capitalization; authority; SEC filings; financial statements; absence of undisclosed liabilities; litigation; absence of certain changes or events; compliance with laws; environmental matters; intellectual property; regulatory compliance; financing and tax matters. The representations and warranties contained in the Allergan Merger Agreement expire at the effective time of the Inamed Merger.
      The representations, warranties and covenants made by Inamed in the Allergan Merger Agreement are qualified by information contained in the disclosure schedules delivered to Allergan and Offeror in connection with the execution of the Allergan Merger Agreement. Stockholders are not third party beneficiaries under the Allergan Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Inamed or any of its affiliates.
No Solicitation of Other Offers by Inamed
      Under the terms of the Allergan Merger Agreement, subject to certain exceptions described below, Inamed has agreed that it and its subsidiaries, and directors, officers and employees of it and its subsidiaries, will not, directly or indirectly:
    solicit, initiate, encourage or induce any inquiry regarding, or the making, submission or announcement of, any proposal to acquire Inamed;
 
  participate in any discussions or negotiations regarding, or furnish any non-public information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, a proposal to acquire Inamed; or
 
  enter into any letter of intent or similar document or contract contemplating or otherwise relating to a proposal to acquire Inamed.
      In addition, under the Allergan Merger Agreement Inamed has agreed that it will immediately cease, and will use its reasonable best efforts to cause its and its respective subsidiaries, attorneys, accountants, investment bankers, financial advisors, agents and other representatives to cease, any and all existing discussions or negotiations with respect to any proposal to acquire Inamed.

Table of Contents

      For purposes of the restrictions described above, a “proposal to acquire Inamed” is any offer or proposal with respect to a potential or proposed:
  merger, consolidation, business combination or similar transaction involving Inamed or any of its significant subsidiaries pursuant to which Inamed’s stockholders immediately prior to such transaction would own less than 85% of the aggregate voting power of the entity surviving or resulting from such transaction (or the ultimate parent entity thereof);
 
  sale, lease, exclusive license or other disposition, directly or indirectly, by merger, consolidation, business combination, share exchange, joint venture or otherwise of the assets of Inamed or its subsidiaries representing 15% or more of the consolidated assets of Inamed and its subsidiaries;
 
  issuance, sale or other disposition (including by way of merger, consolidation, business combination, share exchange, joint venture or any similar transaction) of securities representing more than 15% of the voting power of Inamed;
 
  transaction in which any person or group of persons acquires beneficial ownership, or the right to acquire beneficial ownership of, 15% or more of the outstanding voting capital stock of Inamed; or
 
  any combination of the above (other than the Offer, the Inamed Merger or the Post-Closing Merger).
      Under the Allergan Merger Agreement, Inamed is obligated to notify Allergan in writing within 48 hours after receiving any proposal to acquire Inamed or any request for nonpublic information or inquiry that could reasonably be expected to lead to any proposal to acquire Inamed. The notice must include the material terms and conditions of the potential proposal, and the identity of the person making the proposal. Inamed also must promptly keep Allergan informed of the status and details of the proposal, and must provide Allergan with a copy of all written materials provided in connection with such proposal.
      Notwithstanding the prohibitions described above, if Inamed receives an unsolicited bona fide written proposal to acquire Inamed made after the Allergan Merger Agreement is executed, Inamed is permitted to participate or engage in discussions or negotiations with, and provide information to, the party making the proposal to acquire Inamed as long as:
  Inamed’s board of directors determines in good faith, after consulting with an independent financial advisor and outside legal counsel, that such proposal constitutes or is reasonably likely to result in a superior proposal as compared to the transaction with Allergan; and
 
    prior to providing any such information, the person making the proposal to acquire Inamed enters into a confidentiality agreement containing terms at least as restrictive as the terms of the confidentiality agreement between Allergan and Inamed and, contemporaneously with furnishing any nonpublic information to such person, Inamed furnishes any such nonpublic information to Allergan.
      Prior to providing any information to, or participating in discussions or negotiations with, the person making the proposal to acquire Inamed, Inamed must provide written notice to Allergan and otherwise comply with the notice and information delivery requirements described above.
      A “superior proposal” for purposes of the Allergan Merger Agreement is an unsolicited, bona fide written offer made by a potential acquirer to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination, all or substantially all of the assets of Inamed, or a majority of the total outstanding voting securities of Inamed and as a result of which the stockholders of Inamed immediately preceding the transaction would hold less than 50% of the equity interests in the surviving or resulting entity or its parent or subsidiary, on terms that are more favorable to Inamed’s stockholders than the terms of the Offer and the Inamed Merger, taking into account, among other matters, all legal, financial, regulatory and other aspects of such offer and the person making the proposal.
      Upon delivering notice to Allergan of Inamed’s receipt of a superior proposal, and if requested by Allergan, Inamed must negotiate in good faith with Allergan to revise the terms of the Allergan Merger Agreement to be superior to those in the purportedly superior proposal to acquire Inamed.

Table of Contents

Changes of Recommendation
      The Allergan Merger Agreement contemplates that the Inamed board of directors will recommend that Inamed stockholders tender their Inamed Shares pursuant to the Offer and adopt and approve the Allergan Merger Agreement.
      The Inamed board of directors or any committee thereof may not:
  withdraw or modify, or publicly propose to withdraw or modify, in a manner adverse to Allergan, the recommendation with respect to the Offer and the adoption and approval of the definitive merger agreement;
 
  approve any letter of intent, agreement in principle, acquisition agreement or similar agreement relating to any proposal to acquire Inamed; or
 
  approve or recommend, or publicly propose to approve or recommend, any proposal to acquire Inamed.
      Notwithstanding the foregoing, the Inamed board of directors may take such actions if, prior to receipt of the approval of stockholders necessary to complete the Inamed Merger:
    the board of directors determines in good faith, after consultation with outside legal counsel, that the failure to withdraw or modify its recommendation would reasonably be likely to constitute a violation of its fiduciary duties under applicable law;
 
    Inamed notifies Allergan in writing of its determination that the failure to withdraw or modify its recommendation would reasonably be likely to constitute a violation of its fiduciary duties under applicable law; and
 
  in the case of any actions taken in connection with a proposal to acquire Inamed, at least five business days following receipt by Allergan of the written notice of the determination of Inamed’s board of directors that the failure to withdraw or modify its recommendation would be reasonably likely to constitute a violation of the directors’ fiduciary duties under applicable law, and taking into account any revised proposal made by Allergan after receiving the notice, Inamed’s board of directors maintains such determination.
      Nothing in the Allergan Merger Agreement prohibits Inamed or its board of directors from taking and disclosing to Inamed’s stockholders a position contemplated by Rule 14d-9 and 14e-2(a) promulgated under the Exchange Act. However, the Inamed board of directors is prohibited from changing its recommendation unless pursuant to the terms of the Allergan Merger Agreement.
Stockholder Approval
      Inamed has agreed to convene a meeting of its stockholders as soon as practicable after the consummation of the Offer, if required by the DGCL, in order to effect the Inamed Merger. Under the Allergan Merger Agreement, Inamed may not submit to the vote of its stockholders any proposal to acquire Inamed from a third party unless the Allergan Merger Agreement is terminated.
Conduct of Business Before Completion of the Merger
Restrictions on Allergan’s Operations
      The Allergan Merger Agreement provides for certain restrictions on Allergan’s activities until either the completion of the Inamed Merger or the termination of the Allergan Merger Agreement. In general, Allergan is required to conduct its business only in the ordinary course consistent with past practice. In addition, unless otherwise approved in writing by Inamed, or as permitted by the Allergan Merger Agreement or as required by

applicable law or the requirements of any stock exchange or regulatory organization applicable to Allergan, Allergan and its subsidiaries may not:
  amend or propose to amend Allergan’s certificate of incorporation, bylaws or similar governing documents;

  take any action or omit to take any action that is intended or would reasonably be expected to result in any of the conditions to the Offer or any of the conditions to the Inamed Merger not being satisfied;
 
  take any action that would result in a failure to maintain trading of Allergan common stock on the NYSE; or
 
  agree, authorize or otherwise to take any of the foregoing actions.
      Notwithstanding the foregoing, the Allergan Merger Agreement expressly permits Allergan to (a) repurchase, retire or refinance outstanding indebtedness or debt securities and (b) enter into negotiations, discussions and contracts relating to, and may consummate, acquisitions of other persons, so long as (i) the fair market value of the total consideration does not exceed $500,000,000 individually, (ii) Allergan does not issue in excess of 20% of the then outstanding Allergan common stock as consideration in any such transaction and (iii) the negotiation or consummation of any such acquisition is not reasonably likely to materially delay or prevent the completion of the Offer or the Inamed Merger.
Restrictions on Inamed’s Operations
      The Allergan Merger Agreement provides for certain restrictions on the activities of Inamed and its subsidiaries until either the completion of the Inamed Merger or the termination of the Allergan Merger Agreement. In general, under the Allergan Merger Agreement, Inamed and its subsidiaries must:
  conduct its business only in the ordinary course consistent with past practice;
 
  use its commercially reasonable efforts to preserve intact its current business organization and goodwill and keep available the services of its current officers, key employees and key independent contractors; and
 
    use its commercially reasonable efforts to preserve its goodwill and business relationships with its customers, suppliers, licensors, licensees, and other persons with which it has business relationships.
      In addition, the Allergan Merger Agreement provides that, prior to the completion of the Inamed Merger, unless otherwise approved in writing by Allergan, or as permitted by the Allergan Merger Agreement or as required by applicable law or the requirements of any stock exchange or regulatory organization applicable to Inamed, Inamed and its subsidiaries may not:
  amend or propose to amend its certificate of incorporation or bylaws or similar governing documents;

Access to Information; Confidentiality
      The Allergan Merger Agreement provides that during the period prior to the effective time of the Inamed Merger, Allergan and Inamed will, and will cause each of their subsidiaries to, afford to the other party and its representatives reasonable access during normal business hours to their respective officers, employees, representatives, properties, books, contracts, commitments, files and records, except that neither party is required to provide the other party with any information that it reasonably believes it can not deliver to the other party due to contractual or legal restrictions, or which it believes is competitively sensitive information. In addition, Inamed must consult with Allergan regarding its business in a prompt manner and on a regular basis.
      Inamed must also provide to Allergan’s financial advisor reasonable access during normal business hours upon reasonable notice throughout the period prior to the effective time of the Inamed Merger to Inamed’s officers, employees, representatives, properties, books, contracts, commitments, files and records and furnish promptly such information concerning Inamed’s business, properties and personnel as Allergan’s financial advisor reasonably requests for the purposes of conducting a customary underwriter due diligence investigation.
Antitrust Approval
      Under the Allergan Merger Agreement, Allergan and Inamed are to cooperate and use their reasonable best efforts to:
  obtain any government clearances or approvals required for the consummation of the Offer or the closing of the Inamed Merger under the HSR Act, and any other federal, state or foreign law or decree designed to prohibit, restrict or regulate actions for the purpose or effect of monopolization or restraint of trade, which we refer to herein collectively as the “antitrust laws”;
 
  to obtain the expiration of any applicable waiting period under any antitrust laws;
 
  to respond to any government requests for information under any antitrust laws;
 
  to contest and resist any action, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order that restricts, prevents or prohibits the consummation of the Inamed Merger or any other transactions contemplated by the Allergan Merger Agreement under any antitrust laws.
      Under the Allergan Merger Agreement, Allergan will determine and direct the strategy and process by which the parties will seek required approvals under antitrust laws; provided that Allergan will consult with and consider in good faith the views of Inamed in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted in connection with proceedings under or relating to any antitrust laws.

Table of Contents

      Notwithstanding the foregoing, under the Allergan Merger Agreement, neither Allergan nor Inamed are required to:
  license, divest, dispose of or hold separate any material assets or businesses or otherwise take or commit to take any action that limits in any material respect its freedom of action with respect to, or its ability to retain, any of its material assets or businesses or that would have a material adverse effect on the combined company;
 
  agree to or effect any license, divestiture, disposition or hold separate any business or take any other action or agree to any limitation that is not conditioned on the consummation of the Offer or the Inamed Merger; or
 
  pay more than de minimis amounts in connection with seeking or obtaining the consents, approvals or authorizations under antitrust laws required to complete the Offer, the Inamed Merger or the Post-Closing Merger.
      The Allergan Merger Agreement provides that Inamed will not take or agree to take any of the foregoing actions without the prior written consent of Allergan, and, if so requested by Allergan, Inamed must use reasonable best efforts to effect any license, divestiture, disposition or hold separate of any of Inamed’s assets or businesses necessary to obtain clearances or approvals required under the antitrust laws, provided that such action is conditioned on the consummation of the Offer.
Inamed Benefit Plans
Stock Options
      Immediately prior to the effective time of the Inamed Merger, each outstanding option under the Inamed stock plans will become fully vested and exercisable. At the effective time of the Inamed Merger and without any action on the part of the parties to the Allergan Merger Agreement or any holder of such stock options, each then outstanding option will be canceled and converted into and will thereafter represent only the right to receive an amount of cash equal to 45% of the “in the money” value of the option and a number of shares of Allergan common stock with a value equal to 55% of the “in the money” value of the option.
      In lieu of any fractional shares of Allergan common stock that otherwise would be issuable with respect to canceled Inamed options, Inamed option holders will receive an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the exchange agent for the Inamed Merger, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock otherwise issuable with respect to cancelled Inamed options.
      The amount of cash and number of shares of Allergan common stock to which an option holder otherwise would be entitled pursuant to the Inamed Merger will be reduced by the total amount of withholding for applicable taxes with respect to the aggregate options canceled and converted into the right to receive cash and Allergan common stock. Amounts for withholding will first be deducted from the amounts of cash otherwise payable to the option holder and, to the extent additional withholding is required, the number of shares of Allergan common stock otherwise deliverable will be reduced by the amount of remaining withholding.
Employee Stock Purchase Plan
      Under the Allergan Merger Agreement, Inamed will be required to take all requisite action with respect to its 2000 Employee Stock Purchase Plan, as amended, to ensure that:
  all outstanding purchase rights will be exercised no later than three business days prior to the expiration date of the Offer;
 
  no purchase rights will be issued and outstanding as of the expiration date of the Offer;

52


Table of Contents

    conditioned upon the occurrence of the closing of the Inamed Merger, the Inamed ESPP will be terminated no later than the effective time of the Inamed Merger; and
 
  no additional offering periods shall commence on or after the expiration date of the Offer.
      Inamed must deliver to Allergan prior to the expiration date of the Offer evidence that the Inamed ESPP will be terminated as of the effective time of the Inamed Merger, conditioned upon the occurrence of the closing of the Inamed Merger.
Restricted Stock
      All outstanding rights that Inamed may hold immediately prior to the effective time of the Inamed Merger to acquire unvested Inamed Shares issued pursuant to the Inamed restricted stock plan will lapse as of the effective time of the Inamed Merger, such that holders of restricted stock will be entitled to receive the merger consideration payable pursuant to the Inamed Merger with respect to their restricted Inamed Shares.
Inamed Benefit Plans
      After the Inamed Merger, benefit plans in effect as of the date of the Allergan Merger Agreement will remain in effect with respect to employees of Inamed or its subsidiaries covered by such plans at the time of the Inamed Merger until such time as Allergan either transfers employees and former employees of Inamed and its subsidiaries to existing benefit plans of Allergan or Offeror or adopts a new benefit plan. Prior to the Inamed Merger, Allergan and Inamed are to cooperate in reviewing, evaluating and analyzing Inamed benefit plans with a view towards determining appropriate transferred employee plans.
      Under the Allergan Merger Agreement, Allergan will, and will cause its subsidiaries to, with respect to all transferred employee plans, to the extent applicable immediately prior to the effective time of the Inamed Merger:
  provide each employee of Inamed with service or other credit for all limitations as to preexisting conditions, exclusions and waiting periods under any transferred employee plan;
 
  provide each employee with credit for any co-payments and deductibles;
 
  provide each employee with credit for all service for purposes of eligibility, vesting and benefit accruals (but not for benefit accruals under any defined benefit pension plan); and
 
  provide benefits under medical, dental, vision and similar health and welfare plans that are in the aggregate no less favorable than those provided to similarly situated employees of Allergan.
      If requested by Allergan at least seven days prior to the effective time of the Inamed Merger, Inamed will terminate any and all benefit plans intended to qualify under Section 401(k) of the Internal Revenue Code, effective not later than the last business day immediately preceding the effective time of the Inamed Merger.
Directors’ and Officers’ Indemnification
      Under the Allergan Merger Agreement, Allergan will, to the fullest extent permitted by law, and will cause Offeror to, honor all of Inamed’s obligations to indemnify its current or former directors or officers for acts or omissions by such directors and officers occurring prior to the effective time of the Inamed Merger. In addition, for a period of six years following the effective time of the Inamed Merger, the certificate of incorporation and bylaws of Offeror must contain provisions no less favorable with respect to indemnification and exculpation of present and former directors and officers of Inamed than are presently set forth in Inamed’s and its subsidiaries’ certificates of incorporation and bylaws.
      For six years after the effective time of the Inamed Merger, under the Allergan Merger Agreement, Allergan will cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by Inamed, although Allergan may substitute policies of at least the same coverage and amounts containing terms and conditions which are no less advantageous with respect to claims arising from or related to facts or events which occurred at or before the effective time of the Inamed Merger. However, Allergan is

53


Table of Contents

not obligated to make annual premium payments for this insurance if the premiums exceed 200% of the annual premiums paid as of the date of the Allergan Merger Agreement by Inamed for such insurance. If the insurance coverage cannot be obtained at all, or can only be obtained at an annual premium in excess of the maximum premium, Allergan will maintain the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to 200% of the annual premiums paid by Inamed.
      Under the Allergan Merger Agreement, instead of the insurance described above, effective as of the effective time of the Inamed Merger, Allergan may require Inamed to purchase a directors’ and officers’ liability insurance “tail” or “runoff” insurance program for a period of six years after the effective time of the Inamed Merger with respect to wrongful acts or omissions committed or allegedly committed at or prior to the effective time of the Inamed Merger instead of providing the insurance coverage described above.
Financing; Allergan Guarantee
      Prior to the closing of the Inamed Merger, Allergan must obtain all financing required for the transactions contemplated by the Allergan Merger Agreement. Allergan will guarantee any payment by Offeror of any amounts payable by Offeror pursuant to the Offer and the Inamed Merger or otherwise pursuant to the Allergan Merger Agreement.
      Under the Allergan Merger Agreement, Inamed must use its reasonable best efforts to cooperate in connection with the arrangement of any financing, including reasonable participation in meetings and road shows, the provision of information reasonably requested by Allergan and reasonable assistance in the preparation of any offering memoranda, private placement memoranda, prospectuses and similar documents prepared by Allergan.
Post-Closing Merger
      The Allergan Merger Agreement provides that, as soon as reasonably practicable after the effective time of the Inamed Merger, Allergan will cause the surviving corporation to adopt an agreement and plan of merger and reorganization whereby Inamed will be merged with and into a wholly owned limited liability company subsidiary of Allergan, with the limited liability company surviving the Post-Closing Merger as a wholly owned subsidiary of Allergan. There are no conditions to this Post-Closing Merger, other than:
  the acquisition of Inamed Shares pursuant to the Offer;
 
  the consummation of the Inamed Merger; and
 
  the absence of any legal prohibitions on completing the Post-Closing Merger.
Termination of the Allergan Merger Agreement
Termination by Allergan or Inamed
      The Allergan Merger Agreement may be terminated at any time before the effective time of the Inamed Merger:
  by mutual written consent of Allergan and Inamed;
 
  by either Allergan or Inamed, if:
    the Offer is not completed by February 28, 2006, subject to extension until March 30, 2006 by either party if all other conditions to the Offer are satisfied or capable of being satisfied and the only reason the Offer has not been completed is that required antitrust approvals have not been obtained and Allergan or Inamed are still attempting to obtain such necessary consents or approvals or are contesting either the refusal of applicable governmental entities to give such required consents or approvals or the entry of a judgment, injunction, order or decree regarding the same. This termination right is not available to any party whose breach of any provision of the Allergan Merger Agreement has caused or resulted in the failure of the Offer to be consummated by such termination date; or

54


Table of Contents

    if any governmental entity shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the consummation of the Offer or the Inamed Merger and such order, decree, ruling or other action is or has become final and nonappealable. This termination right is not available to any party whose breach of any provision of the Allergan Merger Agreement is the cause of or resulted in such order, decree, ruling or other action.
Termination by Allergan
      Under the Allergan Merger Agreement, Allergan may terminate the Allergan Merger Agreement if:
    there has been a breach by Inamed of its representations, warranties, covenants or agreements contained in the Allergan Merger Agreement that would result in a failure of a condition to the Offer that is not waived by Offeror; provided, that Allergan must first give Inamed prior written notice of Allergan’s intent to terminate the Allergan Merger Agreement and Inamed must not have cured the applicable breach within ten business days or, if sooner, by one business day prior to the termination date; or
 
    (i) Inamed’s board of directors effects a Company Change of Recommendation (as defined in the Allergan Merger Agreement) or resolves to do so; (ii) Inamed’s board of directors approves or recommends to Inamed’s stockholders another proposal to acquire Inamed or resolved to do so; or (iii) a tender offer or exchange offer for Inamed Shares is commenced (other than by Allergan or any of its affiliates) and Inamed’s board of directors recommends that Inamed’s stockholders tender their shares in such tender offer or exchange offer or Inamed’s board of directors fails to recommend that Inamed’s stockholders reject such tender offer or exchange offer within seven business days after receipt of Allergan’s request to do so.
Termination by Inamed
      Inamed may terminate the Allergan Merger Agreement if:
    Allergan fails to consummate the Offer in breach of the Allergan Merger Agreement or if there has been a breach by Allergan or Offeror of (x) its representations and warranties, except where the failure of such representations and warranties to be true and correct (without giving effect to any limitation as to “materiality” or “Parent Material Adverse Effect” set forth therein) would not, individually or in the aggregate, result in a Parent Material Adverse Effect (as defined in the Allergan Merger Agreement), or (y) its covenants and agreements contained in the Allergan Merger Agreement in any material respect, provided, that Inamed must first give Allergan prior written notice of Inamed’s intent to terminate the Allergan Merger Agreement and Allergan must not have cured the applicable breach within ten business days or, if sooner, by one business day prior to the termination date; or
 
    prior to consummation of the Offer, upon or following a Company Change in Recommendation or otherwise in order to enter into a definitive agreement with respect to or otherwise to accept a superior proposal, in either case as permitted by the Allergan Merger Agreement and subject to the timely payment in full of any termination fees payable by Inamed pursuant to the Allergan Merger Agreement.
Termination Fees and Expenses
      Except as set forth below, all costs and expenses incurred in connection with the Allergan Merger Agreement will be paid by the party incurring the same.
Inamed Termination Fees
      The Allergan Merger Agreement provides that Inamed will pay Allergan $10 million within two business days following termination if the Allergan Merger Agreement is terminated by Allergan due to Inamed’s

55


Table of Contents

breach of any representation, warranty, covenant or agreement which would result in a failure of a condition to the Offer that is not waived by Offeror; provided that Allergan has given Inamed prior written notice of Allergan’s intent to terminate the Allergan Merger Agreement and Inamed has not cured the applicable breach within ten business days or, if sooner, by one business day prior to the termination date.
      The Allergan Merger Agreement provides that Inamed will pay Allergan a termination fee of $100 million, less any amount previously paid as specified above, at the earlier of the date that Inamed enters into a definitive agreement providing for an acquisition of Inamed or the date of the consummation of such a transaction if:
  prior to consummation of the Offer, any person publicly announces a proposal to acquire Inamed which has not been expressly and bona fide publicly withdrawn;
 
    the Allergan Merger Agreement is terminated by either Inamed or Allergan (i) because the Offer has not been consummated on or before February 28, 2006 (or March 30, 2006 if extended) and at the time of termination, the registration statement has become effective and Inamed has not performed in all material respects all of its obligations required to be performed by it pursuant to the Allergan Merger Agreement at or prior to the completion of the Offer or there shall not have been validly tendered prior to the expiration date of the Offer at least a majority of the outstanding Inamed Shares on a fully diluted basis or (ii) by Allergan as a result of a breach by Inamed of a covenant or other affirmation obligation that would result in the failure of a condition to the Offer; and
 
  within 12 months after the date of termination of the Allergan Merger Agreement, Inamed enters into a definitive agreement with respect to an acquisition of Inamed or consummates such a transaction.
      The Allergan Merger Agreement further provides that Inamed will pay Allergan a termination fee of $100 million within two business days following termination of the Allergan Merger Agreement if the Allergan Merger Agreement is terminated by Allergan because:
    the Inamed board of directors effects a Company Change of Recommendation (as defined in the Allergan Merger Agreement), or resolves to do so;
 
  the Inamed board of directors approves or recommends to Inamed stockholders a proposal to acquire Inamed, or resolves to do so; or
 
    a tender or exchange offer for Inamed Shares is commenced (other than by Allergan or any of its affiliates) and the Inamed board of directors recommends that the Inamed stockholders tender their shares in such tender or exchange offer or fails to recommend that the Inamed stockholders reject such tender or exchange offer within seven business days after receipt of Allergan’s request to do so.
      Inamed will also pay Allergan a termination fee of $100 million concurrently with the termination of the Allergan Merger Agreement if the Allergan Merger Agreement is terminated by Inamed prior to the completion of the Offer, upon or following a Company Change of Recommendation or otherwise in order for Inamed to enter into a definitive agreement with respect to or otherwise to accept a proposal to acquire Inamed.
     Allergan Termination Fees
      The Allergan Merger Agreement provides that Allergan will pay Inamed $10 million within two business days following termination if the Allergan Merger Agreement is terminated by Inamed because (i) Allergan fails to consummate the Offer in breach of the Allergan Merger Agreement, or (ii) there has been a breach by Allergan or Offeror of (x) its representations and warranties contained in the Allergan Merger Agreement, except where the failure of such representations and warranties to be true and correct (without giving effect to any limitation as to “materiality” or “Parent Material Adverse Effect” set forth therein) would not, individually or in the aggregate, result in a Parent Material Adverse Effect, or (y) its covenants and agreements contained in the Allergan Merger Agreement in any material respect; provided that Inamed has given Allergan prior written notice of Inamed’s intent to terminate the Allergan Merger Agreement and

56


Table of Contents

Allergan has not cured the applicable breach within ten business days, or, if sooner, by one business day prior to the termination date.
      Under the Allergan Merger Agreement, Allergan will also pay Inamed a termination fee of $90 million, in addition to any amount previously paid as specified above, within two business days following the date of termination if:
  Inamed has been required to pay Medicis the $90 million termination fee under the Medicis merger agreement; and
 
  the Offer is not consummated and Inamed terminates the Allergan Merger Agreement because (i) Allergan fails to consummate the Offer in breach of the Allergan Merger Agreement, or (ii) there has been a breach by Allergan or Offeror of (x) its representations and warranties, except where the failure of such representations and warranties to be true and correct (without giving effect to any limitation as to “materiality” or “Parent Material Adverse Effect” set forth therein) would not, individually or in the aggregate, result in a Parent Material Adverse Effect, or (y) its covenants and agreements contained in the Allergan Merger Agreement in any material respect; provided that Inamed has given Allergan prior written notice of Inamed’s intent to terminate the Allergan Merger Agreement and Allergan has not cured the applicable breach within ten business days, or, if sooner, by one business day prior to the termination date; or
 
  the Offer is not consummated on or prior to the termination date and the antitrust conditions in the Allergan Merger Agreement have not been satisfied (unless such conditions have not been satisfied because Inamed has been unable to divest the Reloxin Assets as contemplated in the Allergan Merger Agreement).
      Inamed will not be entitled to such Allergan termination fees if Inamed elects to file suit or otherwise seeks to recover money damages from Allergan.
Effect of Termination
      In the event of termination of the Allergan Merger Agreement prior to the effective time of the Inamed Merger in accordance with the terms of the Allergan Merger Agreement, the Allergan Merger Agreement will become void, and there shall be no liability or further obligation on the part of Allergan, Offeror, or Inamed, except to the extent that the termination results from the willful and material breach by a party of the Allergan Merger Agreement, and other than the payment of fees and expenses described above under “—Termination Fees and Expenses,” certain provisions relating to confidentiality, and certain general provisions which will survive the termination.
Stock Exchange Listing
      The Allergan Merger Agreement provides that Allergan will use all reasonable efforts to cause the shares of Allergan common stock to be issued pursuant to the Offer and in the Inamed Merger to be approved for listing on the NYSE, subject to official notice of issuance.
Tax Treatment
      Allergan and Inamed intend the Inamed Merger, taken together with the Offer and the Post-Closing Merger, to qualify for United States federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. Each of Allergan, Offeror and Inamed shall use its best efforts to cause the Inamed Merger, taken together with the Offer and the Post-Closing Merger, to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. None of Allergan, Offeror, Company, or their respective subsidiaries shall take, or agree to take, any action (including any action otherwise permitted by the Allergan Merger Agreement) that could prevent or impede the Inamed Merger, taken together with the Offer and the Post-Closing Merger, from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

Amendments, Extensions and Waivers
Amendments
      The Allergan Merger Agreement may be amended by the parties at any time before or after any Inamed stockholder approval has been obtained; provided that after the Inamed stockholders adopt the Allergan Merger Agreement and approve the Inamed Merger, the Allergen Merger Agreement cannot be amended if by law further approval of the stockholders is required, without such approval.
Extensions and Waivers
      Under the Allergan Merger Agreement, at any time prior to the effective time of the Inamed Merger, any party may:
  extend the time for the performance of any of the obligations or other acts of the other parties;
 
  waive any inaccuracies in the representations and warranties of the other parties; or
 
  waive compliance by the other parties with any of the agreements or conditions contained in the Allergan Merger Agreement (except for those conditions not waivable pursuant to the Allergan Merger Agreement); provided that after the Inamed stockholders adopt the Allergan Merger Agreement and approve the Inamed Merger, no waiver can be given if by law further approval by the Inamed stockholders is required, without such approval.

THE OFFER
      Offeror is offering to exchange each outstanding Inamed Share for cash or Allergan common stock, at the election of the tendering Inamed stockholder, subject to the conditions contained in this prospectus and the accompanying letter of election and transmittal.
      Offeror is making the Offer in order for Allergan to acquire control of, and ultimately the entire equity interest in, Inamed. The Offer is the first step in Allergan’s acquisition of Inamed and is intended to facilitate the acquisition of all Inamed Shares. Allergan intends to seek to complete the Inamed Merger as soon as possible after completion of the Offer. Promptly after the Inamed Merger, Allergan will consummate the Post-Closing Merger.
Consideration
      Under the terms of the Offer, each Inamed stockholder will have the opportunity to elect to receive, for each Inamed Share validly tendered and not properly withdrawn, either:
  $84.00 in cash, without interest; or
 
  0.8498 of a share of newly issued Allergan common stock,
subject to the proration and election procedures described in this prospectus and the related letter of election and transmittal.
      In the Offer:
  45% of the aggregate Inamed Shares tendered in the Offer will be exchanged for cash, and
 
  55% of the aggregate Inamed Shares tendered in the Offer will be exchanged for shares of Allergan common stock;
therefore, elections will be subject to proration if tendering holders of Inamed Shares, in the aggregate, elect to receive more than the maximum amount of consideration to be paid as cash or shares of Allergan common stock.
      Based on the closing price of Allergan common stock on the New York Stock Exchange on December 21, 2005, the most recent practicable date prior to the date of this prospectus, 0.8498 of an Allergan share had a value of $91.19 per share. The value of 0.8498 of an Allergan share will fluctuate prior to the expiration date of the Offer as the market price of Allergan common stock changes. At Allergan share prices of $98.85 and above, the value of 0.8498 of an Allergan share will exceed the cash offer of $84.00 per Inamed Share, and at Allergan share prices below $98.85, the cash offer will exceed the value of 0.8498 of an Allergan share.

59


Table of Contents

      Solely for purposes of illustration, the following table reflects the per share amount of cash and the market value of the Allergan common stock that an Inamed stockholder would receive for each Inamed Share tendered pursuant to the Offer if exactly 55% of the Inamed Shares tendered by the stockholder were exchanged for Allergan common stock and 45% of such shares were exchanged for cash. This would be the case, for example, if all tendering Inamed stockholders made the same election for either cash or Allergan shares. In that circumstance, each Inamed Share would be exchanged, on average, for $37.80 in cash (i.e. 45% of $84.00) and 0.46739 shares (i.e. 55% of 0.8498) of Allergan common stock. The table indicates the relative value, in that circumstance, of the two forms of consideration at different market values for the Allergan shares.
                             
Assumed           Implied Value
Market Price   Value of 0.46739 of   Cash Amount Paid   (per Inamed Share
(per Allergan Share)   an Allergan Share   (per Inamed Share)   exchanged)
             
$ 85.00     $ 39.73     $ 37.80     $ 77.53  
$ 90.00     $ 42.07     $ 37.80     $ 79.87  
$ 95.00     $ 44.40     $ 37.80     $ 82.20  
$ 100.00     $ 46.74     $ 37.80     $ 84.54  
$ 105.00     $ 49.08     $ 37.80     $ 86.88  
$ 110.00     $ 51.41     $ 37.80     $ 89.21  
$ 115.00     $ 53.75     $ 37.80     $ 91.55  
      The market prices of Allergan common stock used in the above table, and the assumptions regarding the mix of cash and/or stock a hypothetical Inamed stockholder would receive are for purposes of illustration only. The price of Allergan common stock fluctuates and may be higher or lower than in these examples at the time the Offer is completed. In addition, due to the proration mechanisms in the Offer, the elections of other Inamed stockholders will impact whether a tendering Inamed stockholder receives the type of consideration elected, or is prorated so that a portion of such stockholder’s tendered shares are exchanged for another form of consideration.
      Inamed stockholders should consider the potential effects of proration and should obtain current market quotations for shares of Allergan common stock and Inamed Shares before deciding whether to tender pursuant to the Offer and before electing the form of Offer consideration they wish to receive.
Elections and Proration
      If Inamed stockholders elect to receive more than the aggregate amount of cash or shares of Allergan common stock available in the Offer, the total cash or stock, as the case may be, will be proportioned among the stockholders who elect each form of consideration as follows:
Over-Election of Allergan Common Stock
      The maximum aggregate shares of Allergan common stock issuable pursuant to the Offer shall be:
  0.8498 of a share of Allergan common stock multiplied by
 
  55% of the total number of Inamed Shares that are tendered and accepted for exchange pursuant to the Offer.
      If holders of Inamed Shares elect to receive shares of Allergan common stock in excess of the maximum aggregate shares of Allergan common stock issuable pursuant to the Offer, then:
  all Inamed Shares covered by elections to receive cash and all Inamed Shares for which no election was made will be exchanged for $84.00 per share in cash; and

60


Table of Contents

  for each election to receive shares of Allergan common stock:
  the number of Inamed Shares subject to such election that will be converted into the right to receive shares of Allergan common stock shall be:
  the total number of Inamed Shares subject to such election to receive Allergan common stock multiplied by
 
  a fraction:
  the numerator of which shall be the maximum number of shares of Allergan common stock issuable in the Offer, and
 
  the denominator of which shall be the product of the aggregate number of Inamed Shares subject to all elections to receive Allergan common stock, multiplied by 0.8498,
                   rounded down to the nearest Inamed Share.
  all other Inamed Shares subject to such election, other than that number converted into the right to receive shares of Allergan common stock as set forth above, shall be converted into the right to receive $84.00 in cash.
      All such prorations shall be applied on a pro rata basis, such that each Inamed stockholder who tenders Inamed Shares subject to an election to receive Allergan common stock bears its proportionate share of the proration.
Over Election of Cash
      The maximum aggregate amount of cash payable pursuant to the Offer shall be:
  $84.00 multiplied by
 
  45% of the total number of Inamed Shares that are tendered and accepted for exchange pursuant to the Offer.
      If holders of Inamed Shares elect to receive cash in excess of the maximum aggregate amount of cash payable in the Offer, then:
  all Inamed Shares covered by elections to receive Allergan common stock and all Inamed Shares for which no election was made will be exchanged for 0.8498 of a share of Allergan common stock; and
 
  for each election to receive cash:
  the number of Inamed Shares that shall be converted into the right to receive cash shall be:
  the total number of Inamed Shares subject to such election to receive cash multiplied by
 
  a fraction:
  the numerator of which shall be the maximum aggregate cash payable in the Offer, and
 
  the denominator of which shall be the product of the aggregate number of Inamed Shares subject to all elections to receive cash, multiplied by $84.00,
  rounded down to the nearest Inamed Share.
  all other Inamed Shares subject to such cash election, other than the number converted into the right to receive cash consideration as set forth above, shall be converted into the right to receive 0.8498 of a share of Allergan common stock.
      All prorations shall be applied on a pro rata basis, such that each Inamed stockholder who tenders Inamed Shares subject to an election to receive cash bears its proportionate share of the proration.

61


Table of Contents

Consequences of Tendering with No Election
      Inamed stockholders who do not make an election will be allocated whatever form of Offer consideration is remaining (or a proportionate share of each form of Offer consideration if neither is oversubscribed), after taking into account the preferences of the tendering stockholders who made valid elections. If neither form of consideration is oversubscribed, Inamed stockholders who do not make an election will each receive the remaining cash and shares of Allergan common stock on a pro rata basis such that after all Inamed Shares for which no election is made are exchanged, 45% of the aggregate Inamed Shares tendered in the Offer will be exchanged for cash and 55% of the aggregate Inamed Shares tendered in the Offer shall be exchanged for shares of Allergan common stock.
Fractional Shares
      Inamed stockholders will not receive any fractional shares of Allergan common stock in the Offer. Instead of receiving any fractional shares of Allergan common stock to which Inamed stockholders otherwise would be entitled, they will receive an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the exchange agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock issued pursuant to the Offer, as described below in “Cash Instead of Fractional Shares of Allergan Common Stock.”
Distribution of Offering Materials
      Pursuant to Exchange Act Rule 14d-5 and Section 220 of the DGCL, Offeror requested Inamed provide access to an Inamed stockholder list and security position listings to communicate with Inamed stockholders and to distribute the Offer materials to Inamed stockholders. Upon compliance by Inamed with this request, the prospectus, the related letter of election and transmittal and other relevant materials were sent to record holders of Inamed Shares and to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on Inamed’s stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing, so that they can in turn send these materials to beneficial owners of Inamed Shares.
Expiration of the Offer
      The Offer is currently scheduled to expire at 5:00 p.m., New York City time on Monday, January 9, 2006. The term “expiration date” means 5:00 p.m., New York City time, on Monday, January 9, 2006, unless Offeror extends the period of time for which the Offer is open, in which case the term “expiration date” means the latest time and date on which the Offer, as so extended, expires. For more information, Inamed stockholders should read the discussion immediately below under “—Extension, Termination and Amendment.”
Extension, Termination and Amendment
      Offeror is not required to accept for exchange or exchange any Inamed shares if the conditions of the Offer are not met. Under the Allergan Merger Agreement Offeror must extend the period of time during which the Offer remains open in increments of no more than 10 business days each, if at the scheduled expiration date, any of the conditions of the Offer have not been satisfied or waived, and Offeror also must extend the Offer for any period required by the SEC applicable to the Offer. The Allergan Merger Agreement provides that the agreement may be terminated if the Offer has not been consummated on or before February 28, 2006 (subject to extension until March 30, 2006, under certain circumstances). See “The Allergan Merger Agreement— Termination of the Allergan Merger Agreement.” Offeror may extend the Offer by giving oral or written notice of such extension to the exchange agent. During any such extension, all Inamed Shares previously tendered and not withdrawn will remain subject to the Offer, subject to each tendering Inamed stockholder’s right to withdraw its Inamed Shares. Inamed stockholders should read the discussion under “—Withdrawal Rights” for more details.

62


Table of Contents

      To the extent legally permissible, Offeror also reserves the right at any time or from time to time:
    to extend the Offer one time only for up to five business days if less than 90% of the total Inamed Shares on a fully diluted basis have been validly tendered and not properly withdrawn at the otherwise scheduled expiration date; and
 
  to waive any condition, other than those not subject to waiver as set forth in “—Conditions of the Offer.”
      In addition, Offeror may terminate the Offer and not exchange Inamed Shares that were previously tendered even if Offeror has accepted, but not paid for, shares in the Offer, if completion of the Offer is illegal or if a governmental authority has commenced or threatened legal action related to the Offer.
      Offeror will effect any extension, termination, amendment or delay by giving oral or written notice to the exchange agent and by making a public announcement promptly thereafter. In the case of an extension, any such announcement will be issued no later than 9:00 a.m., New York City time, on the next business day following the previously scheduled expiration date. Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require that any material change in the information published, sent or given to stockholders in connection with the Offer be promptly disseminated to stockholders in a manner reasonably designed to inform them of such change) and without limiting the manner in which Offeror may choose to make any public announcement, Offeror assumes no obligation to publish, advertise or otherwise communicate any such public announcement of this type other than by issuing a press release to the Dow Jones News Service.
      If Offeror materially changes the terms of the Offer or the information concerning the Offer, or if Offeror waives a material condition of the Offer, Offeror will extend the Offer to the extent legally required under the Exchange Act. If, prior to the expiration date, Offeror changes the percentage of Inamed Shares being sought or the consideration offered, that change will apply to all holders whose Inamed Shares are accepted for exchange pursuant to the Offer. If at the time notice of that change is first published, sent or given to Inamed stockholders, the Offer is scheduled to expire at any time earlier than the tenth business day from and including the date that such notice is first so published, sent or given, Offeror will extend the Offer until the expiration of that ten business day period. For purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.
      No subsequent offering period will be available after the Offer.
Conditions of the Offer
      Pursuant to the terms of the Allergan Merger Agreement, Offeror is not required to accept for exchange or exchange any Inamed Shares, may postpone the acceptance for exchange, or exchange, of tendered Inamed Shares if at the scheduled expiration date of the Offer any of the conditions to the Offer are not met, and Offeror may, in its reasonable discretion (but subject to the requirements of applicable laws) terminate or amend the Offer in accordance with the Allergan Merger Agreement if the following conditions are not met. The conditions to the Offer are as follows:

Under the Allergan Merger Agreement, Inamed must consent before (A) Offeror waives the minimum tender condition described above, (B) Offeror adds any conditions to the Offer (C) Offeror modifies any Condition to the Offer in any manner adverse to the holders of Inamed Shares or (D) Offeror changes the form of consideration.
Exchange of Inamed Shares; Delivery of Cash and Shares of Allergan Common Stock
      Allergan has retained Wells Fargo Bank, N.A. as the depositary and exchange agent for the Offer to handle the exchange of Inamed Shares for the offer consideration, including the sale of any fractional shares in the public markets and the payment of the proceeds of such sales to the stockholders on whose behalf such fractional shares are sold.
      Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), Offeror will accept for exchange, and will exchange, Inamed Shares validly tendered and not properly withdrawn promptly after the expiration date. In all cases, exchanges of Inamed Shares tendered and accepted for exchange pursuant to the Offer will be made only after timely receipt by the exchange agent of certificates for those Inamed Shares, or a confirmation of a book-entry transfer of those Inamed Shares into the exchange agent’s account at The Depository Trust Company (“DTC”), a properly completed and duly executed letter of election and transmittal, or an agent’s message in connection with a book-entry transfer, and any other required documents.
      For purposes of the Offer, Offeror will be deemed to have accepted for exchange Inamed Shares validly tendered and not properly withdrawn if and when it notifies the exchange agent of its acceptance of those Inamed Shares pursuant to the Offer. The exchange agent will deliver any cash and shares of Allergan common stock issuable in exchange for Inamed Shares validly tendered and accepted pursuant to the Offer and cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the exchange agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock issued pursuant to the Offer instead of fractional shares of Allergan common stock as soon as practicable after receipt of such notice. The exchange agent will act as the agent for tendering Inamed stockholders for the purpose of receiving cash and shares of Allergan common stock from Offeror and transmitting such cash and stock to the tendering Inamed stockholders. Inamed stockholders will not receive any interest on any cash that Offeror pays in the Offer, even if there is a delay in making the exchange.

65


Table of Contents

      If Offeror does not accept any tendered Inamed Shares for exchange pursuant to the terms and conditions of the Offer for any reason, or if certificates are submitted representing more Inamed Shares than are being tendered, Offeror will return certificates for such unexchanged Inamed Shares without expense to the tendering stockholder or, in the case of Inamed Shares tendered by book-entry transfer into the exchange agent’s account at DTC pursuant to the procedures set forth below in “—Procedure for Tendering,” the Inamed Shares to be returned will be credited to an account maintained with DTC as soon as practicable following expiration or termination of the Offer.
Cash Instead of Fractional Shares of Allergan Common Stock
      Instead of any fractional shares of Allergan common stock that otherwise would be issuable pursuant to the Offer, each holder of Inamed Shares who otherwise would be entitled to receive a fraction of a share of Allergan common stock pursuant to the Offer will be paid an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the exchange agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Allergan common stock issued pursuant to the Offer. As soon as practicable following the completion of the Offer, the exchange agent shall determine the excess of (i) the number of whole shares of Parent Stock issuable to the former holders of Shares pursuant to the Offer including fractional shares, over (ii) the aggregate number of whole shares of Parent Stock to be distributed to former holders of Shares (such excess being collectively called the “Excess Offer Allergan common stock”). The exchange agent, shall as promptly as reasonably practicable sell the Excess Offer Allergan common stock at the prevailing prices on the New York Stock Exchange through one or more member firms of the New York Stock Exchange and shall be executed in round lots to the extent practicable. As soon as practicable after the determination of the amount of cash to be paid to former holders of Inamed Shares in respect of any fractional shares of Allergan common stock, the exchange agent shall distribute such amounts to such former holders.
Withdrawal Rights
      Inamed stockholders can withdraw tendered Inamed Shares at any time until the Offer expires and, if Offeror has not agreed to accept the shares for exchange in the Offer by January 20, 2006, Inamed stockholders can withdraw their Inamed Shares from tender at any time after such date until Offeror accepts the shares for exchange.
      For the withdrawal of Inamed Shares to be effective, the exchange agent must receive a written notice of withdrawal from the Inamed stockholder at one of its addresses set forth on the back cover of this prospectus, prior to the expiration date. The notice must include the stockholder’s name, address, social security number, the certificate number(s), the number of Inamed Shares to be withdrawn and the name of the registered holder, if it is different from that of the person who tendered those shares, and any other information required pursuant to the Offer or the procedures of DTC, if applicable.
      A financial institution must guarantee all signatures on the notice of withdrawal, unless the Inamed Shares to be withdrawn were tendered for the account of an eligible institution. Most banks, savings and loan associations and brokerage houses are able to provide signature guarantees. An “eligible institution” is a financial institution that is a participant in the Securities Transfer Agents Medallion Program.
      If Inamed Shares have been tendered pursuant to the procedures for book-entry tender discussed under the section entitled “—Procedure for Tendering,” any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn shares and must otherwise comply with DTC’s procedures. If certificates have been delivered or otherwise identified to the exchange agent, the name of the registered holder and the serial numbers of the particular certificates evidencing the Inamed Shares withdrawn must also be furnished to the exchange agent, as stated above, prior to the physical release of such certificates.
      Offeror will decide all questions as to the form and validity (including time of receipt) of any notice of withdrawal in its sole discretion, and its decision shall be final and binding. None of Offeror, Allergan, the exchange agent, the information agent, the dealer manager or any other person is under any duty to give notification of any defects or irregularities in any tender or notice of withdrawal or will incur any liability for

66


Table of Contents

failure to give any such notification. Any Inamed Shares properly withdrawn will be deemed not to have been validly tendered for purposes of the Offer. However, an Inamed stockholder may retender withdrawn Inamed Shares by following the applicable procedures discussed under the sections “—Procedure for Tendering” or “—Guaranteed Delivery” at any time prior to the expiration date.
Procedure for Tendering
      For an Inamed stockholder to validly tender Inamed Shares pursuant to the Offer:
  a properly completed and duly executed letter of election and transmittal, along with any required signature guarantees, any other required documents, and certificates for tendered Inamed Shares held in certificate form must be received by the exchange agent at one of its addresses set forth on the back cover of this prospectus before the expiration date; or
 
  an agent’s message in connection with a book-entry transfer, and any other required documents, must be received by the exchange agent at one of its addresses set forth on the back cover of this prospectus, and the Inamed Shares must be tendered into the exchange agent’s account at DTC pursuant to the procedures for book-entry tender set forth below (and a confirmation of receipt of such tender, referred to as a “book-entry confirmation” must be received), in each case before the expiration date; or
 
  the terms and conditions of the guaranteed delivery procedure set forth below under “—Guaranteed Delivery” must be met.
      The term “agent’s message” means a message transmitted by DTC to, and received by, the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from the DTC participant tendering the Inamed Shares that are the subject of such book-entry confirmation, that such participant has received and agrees to be bound by the terms of the letter of election and transmittal and that Offeror may enforce that agreement against such participant.
      The exchange agent has established an account with respect to the Inamed Shares at DTC in connection with the Offer, and any financial institution that is a participant in DTC may make book-entry delivery of Inamed Shares by causing DTC to transfer such shares prior to the expiration date into the exchange agent’s account in accordance with DTC’s procedure for such transfer. However, although delivery of Inamed Shares may be effected through book-entry transfer at DTC, the letter of election and transmittal with any required signature guarantees, or an agent’s message, along with any other required documents, must, in any case, be received by the exchange agent at one of its addresses set forth on the back cover of this prospectus prior to the expiration date, or the guaranteed delivery procedures described below must be followed. Offeror cannot assure Inamed stockholders that book-entry delivery of Inamed Shares will be available. If book-entry delivery is not available, Inamed stockholders must tender Inamed Shares by means of delivery of Inamed Share certificates or pursuant to the guaranteed delivery procedure set forth below under “—Guaranteed Delivery.”
      Signatures on all letters of election and transmittal must be guaranteed by an eligible institution, except in cases in which Inamed Shares are tendered either by a registered holder of Inamed Shares who has not completed the box entitled “Special Issuance Instructions” or the box entitled “Special Delivery Instructions” on the letter of election and transmittal or for the account of an eligible institution.
      If the certificates for Inamed Shares are registered in the name of a person other than the person who signs the letter of election and transmittal, or if certificates for unexchanged Inamed Shares are to be issued to a person other than the registered holder(s), the certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered owner or owners appear on the certificates, with the signature(s) on the certificates or stock powers guaranteed by an eligible institution.
      Inamed stockholders must tender one Inamed preferred stock purchase right for each Inamed Share tendered to effect a valid tender, whether or not a distribution of the rights has occurred, unless the Board of Directors of Inamed has previously redeemed the Inamed rights. Nevertheless, if the Inamed rights have been distributed, Offeror will be entitled to accept for exchange Inamed Shares prior to receipt of the associated

67


Table of Contents

Inamed rights certificate and, subject to complying with SEC rules and regulations, withhold payment of all or a portion of the Offer consideration until receipt of the rights certificate or a book entry transfer of such rights.
      The method of delivery of Inamed Share certificates and all other required documents, including delivery through DTC, is at the option and risk of the tendering Inamed stockholder, and delivery will be deemed made only when actually received by the exchange agent. If delivery is by mail, Offeror recommends registered mail with return receipt requested, properly insured. In all cases, Inamed stockholders should allow sufficient time to ensure timely delivery.
      To prevent backup United States federal income tax withholding, each Inamed stockholder must provide the exchange agent with its correct Taxpayer Identification Number and certify whether it is subject to backup withholding of Federal income tax by completing the Substitute Form W-9 included in the letter of election and transmittal. Some stockholders (including, among others, all corporations and some foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, the stockholder must submit an Internal Revenue Service Form W-8BEN, or other applicable Form W-8, signed under penalties of perjury, attesting to that individual’s exempt status.
      The tender of Inamed Shares pursuant to any of the procedures described above will constitute a binding agreement between Offeror and the tendering Inamed stockholder upon the terms and subject to the conditions of the Offer.
Guaranteed Delivery
      Inamed stockholders desiring to tender Inamed Shares pursuant to the Offer but whose certificates are not immediately available or cannot otherwise be delivered with all other required documents to the exchange agent prior to the expiration date or who cannot complete the procedure for book-entry transfer on a timely basis, may nevertheless tender Inamed Shares, as long as all of the following conditions are satisfied:
  the tender is by or through an eligible institution;
 
  a properly completed and duly executed notice of guaranteed delivery, substantially in the form made available by Offeror, is received by the exchange agent as provided below on or prior to the expiration date; and
 
  the certificates for all tendered Inamed Shares (or a confirmation of a book-entry transfer of such shares into the exchange agent’s account at DTC as described above), in proper form for transfer, together with a properly completed and duly executed letter of election and transmittal with any required signature guarantees (or, in the case of a book-entry transfer, an agent’s message) and all other documents required by the letter of election and transmittal are received by the exchange agent at one of its addresses on the back cover of this prospectus within three NYSE trading days after the date of execution of such notice of guaranteed delivery.
      An Inamed stockholder may deliver the notice of guaranteed delivery by hand, facsimile transmission or mail to the exchange agent at one of its addresses on the back cover of this prospectus. The notice must include a guarantee by an eligible institution in the form set forth in the notice.
      In all cases, Offeror will exchange Inamed Shares tendered and accepted for exchange pursuant to the Offer only after timely receipt by the exchange agent of certificates for Inamed Shares (or timely confirmation of a book-entry transfer of such shares into the exchange agent’s account at DTC as described above), a properly completed and duly executed letter of election and transmittal (or an agent’s message in connection with a book-entry transfer) and any other required documents.
Grant of Proxy
      By executing a letter of election and transmittal as set forth above, an Inamed stockholder irrevocably appoints Offeror’s designees as such stockholder’s attorneys-in-fact and proxies, each with full power of substitution, to the full extent of such stockholder’s rights with respect to its Inamed Shares tendered and

68


Table of Contents

accepted for exchange by Offeror and with respect to any and all other Inamed Shares and other securities issued or issuable in respect of those Inamed Shares on or after the expiration date. That appointment is effective, and voting rights will be affected, when and only to the extent that Offeror accepts tendered Inamed Shares for exchange pursuant to the Offer and deposits with the exchange agent the cash consideration or the shares of Allergan common stock consideration for such Inamed Shares. All such proxies shall be considered coupled with an interest in the tendered Inamed Shares and therefore shall not be revocable. Upon the effectiveness of such appointment, all prior proxies that the Inamed stockholder has given will be revoked, and such stockholder may not give any subsequent proxies (and, if given, they will not be deemed effective). Offeror’s designees will, with respect to the Inamed Shares for which the appointment is effective, be empowered, among other things, to exercise all of such stockholder’s voting and other rights as they, in their sole discretion, deem proper at any annual, special or adjourned meeting of Inamed’s stockholders or otherwise, including the meeting of the Inamed stockholders to vote on the Medicis Merger. Offeror reserves the right to require that, in order for Inamed Shares to be deemed validly tendered, immediately upon the exchange of such shares, Offeror must be able to exercise full voting rights with respect to such shares. However, prior to acceptance for exchange by Offeror in accordance with terms of the Offer, the appointment will not be effective, and, Offeror shall have no voting rights as a result of the tender of Inamed Shares.
Fees and Commissions
      Tendering registered Inamed stockholders who tender Inamed Shares directly to the exchange agent will not be obligated to pay any charges or expenses of the exchange agent or any brokerage commissions. Tendering Inamed stockholders who hold shares through a broker or bank should consult that institution as to whether or not such institution will charge the stockholder any service fees in connection with tendering Inamed Shares pursuant to the Offer. Except as set forth in the instructions to the letter of election and transmittal, transfer taxes on the exchange of Inamed Shares pursuant to the Offer will be paid by Offeror.
Matters Concerning Validity and Eligibility
      Offeror will determine questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of Inamed Shares, in its sole discretion, and its determination shall be final and binding. Offeror reserves the absolute right to reject any and all tenders of Inamed Shares that it determines are not in the proper form or the acceptance of or exchange for which may, in the opinion of its counsel, be unlawful. Offeror also reserves the absolute right to waive any defect or irregularity in the tender of any Inamed Shares. No tender of Inamed Shares will be deemed to have been validly made until all defects and irregularities in tenders of Inamed Shares have been cured or waived. None of Offeror, Allergan, the exchange agent, the information agent, the dealer manager nor any other person will be under any duty to give notification of any defects or irregularities in the tender of any Inamed Shares or will incur any liability for failure to give any such notification. Offeror’s interpretation of the terms and conditions of the Offer (including the letter of election and transmittal and instructions thereto) will be final and binding.
      Inamed stockholders who have any questions about the procedure for tendering Inamed Shares in the Offer should contact the information agent or the dealer manager at their respective addresses and telephone numbers set forth on the back cover of this prospectus.
Announcement of Results of the Offer
      Allergan will announce the final results of the Offer, including whether all of the conditions to the Offer have been satisfied or waived and whether Offeror will accept the tendered Inamed Shares for exchange, as promptly as practicable following the expiration of the Offer. The announcement will be made by a press release in accordance with applicable New York Stock Exchange requirements.

Ownership of Allergan After the Offer and the Inamed Merger
      Assuming that:
    all outstanding options to purchase Inamed Shares, of which Inamed represented there were 1,057,342 as of December 13, 2005, are exercised prior to the expiration of the Offer or the consummation of the Inamed Merger;
 
    Offeror exchanges, pursuant to the Offer and the Inamed Merger, 37,958,370 Inamed Shares, which number is the sum of (i) 36,901,028, the total number of Inamed Shares Inamed represented there were outstanding on December 13, 2005, and (ii) 1,057,342 shares assumed to have been issued pursuant to the exercise of Inamed stock options; and
 
  134,254,772 shares of Allergan common stock are outstanding immediately prior to the consummation of the Inamed Merger;
former Inamed stockholders would own in the aggregate approximately 11% of the outstanding shares of Allergan common stock if 100% of the Inamed Shares are exchanged in the Offer.
Material U.S. Federal Income Tax Consequences
      The following discussion is the opinion of Gibson, Dunn & Crutcher LLP, tax counsel to Allergan, as to the material U.S. federal income tax consequences of the Offer, Inamed Merger, and the Post-Closing Merger to Inamed stockholders. This discussion is based on the Code, the related Treasury regulations, administrative interpretations and court decisions, all of which are subject to change, possibly with retroactive effect. Any such change could affect the accuracy of the statements and the conclusions discussed below and the tax consequences of the Offer, Inamed Merger, and the Post-Closing Merger. This discussion applies only to Inamed stockholders that hold their shares of Inamed common stock, and will hold any shares of Allergan common stock received in exchange for their shares of Inamed common stock, as capital assets within the meaning of Section 1221 of the Code. This discussion does not address all federal income tax consequences of the Offer, Inamed Merger, and Post-Closing Merger that may be relevant to particular holders, including holders that are subject to special tax rules. Some examples of holders that are subject to special tax rules are: dealers in securities; financial institutions; insurance companies; tax-exempt organizations; holders of shares of Inamed stock as part of a position in a “straddle” or as part of a “hedging” or “conversion” transaction; holders who have a “functional currency” other than the U.S. dollar; holders who are foreign persons; holders who own their shares indirectly through partnerships, trusts or other entities that may be subject to special treatment; and holders who acquired their shares of Inamed common stock through stock option or stock purchase programs or otherwise as compensation.
      In addition, this discussion does not address any consequences arising under the laws of any state, local or foreign jurisdiction. INAMED STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO SPECIFIC TAX CONSEQUENCES TO THEM OF THE OFFER, THE INAMED MERGER, AND THE POST-CLOSING MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.
Treatment of the Offer, the Inamed Merger, and the Post-Closing Merger as a Reorganization
      In the opinion of Gibson, Dunn & Crutcher LLP, the Offer, the Inamed Merger, and the Post-Closing Merger will be treated as a single integrated transaction that qualifies as a reorganization within the meaning of Section 368(a) of the Code. This opinion of counsel is given in reliance on customary representations and assumptions as to certain factual matters, including the following: (i) the Offer, the Inamed Merger, and the Post-Closing Merger will take place in accordance with all of the terms and conditions of the Offer, the Inamed Merger, and the Post-Closing Merger as described in this prospectus without the waiver or modification of any of those terms or conditions, (ii) none of Allergan, Inamed, or any related party acquires or redeems, in connection with the Offer or the Inamed Merger, shares of Allergan common stock issued to Inamed stockholders pursuant to the Offer or the Inamed Merger (other than pursuant to an open market

70


Table of Contents

stock repurchase program), (iii) after the Offer, the Inamed Merger, and the Post-Closing Merger, Allergan’s wholly-owned LLC will continue Inamed’s historic business (other than the Reloxin business) or will use a significant portion of the Inamed’s historic business assets in a business, and (iv) the description of Inamed’s business operations set forth in its SEC filings is accurate in all material respects and there will be no material changes in such operations prior to the closing of the Inamed Merger.
      Allergan does not intend to obtain a ruling from the Internal Revenue Service with respect to the federal income tax consequences of the Offer and the Inamed Merger. The opinion of counsel will not bind the courts or the Internal Revenue Service, nor will they preclude the Internal Revenue Service from adopting a position contrary to those expressed in the opinion. No assurance can be given that contrary positions will not successfully be asserted by the Internal Revenue Service or adopted by a court if the issues are litigated. In addition, the opinion of counsel is being delivered prior to the consummation of the proposed transaction and therefore is prospective and dependent on future events. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, or future factual developments, would not adversely affect the accuracy of the conclusion stated herein. The following are the material federal income tax consequences to Inamed stockholders who, consistent with the opinion of counsel referred to above, receive their shares of Allergan common stock and/or cash pursuant to a transaction constituting a reorganization within the meaning of Section 368(a) of the Internal Revenue Code.
      The U.S. federal income tax consequences of the Offer, the Inamed Merger, and Post-Closing Merger to each Inamed stockholder will vary depending on whether the Inamed stockholder receives cash, Allergan common stock, or a combination of cash and Allergan common stock in exchange for the stockholder’s shares of Inamed common stock. At the time that an Inamed stockholder makes an election to receive cash or stock, the stockholder will not know if, and to what extent, the proration procedures will alter the mix of consideration to be received. As a result, the tax consequences to each stockholder will not be ascertainable with certainty until the stockholder knows the amount of cash and /or stock that will be received as a result of the Offer and /or the Inamed Merger.
Consequences to Inamed Stockholders
Holders who Exchange Inamed Shares Solely for Cash
      Holders of Inamed Shares who exchange all their Inamed Shares solely for cash in the Offer or the Inamed Merger will generally recognize gain or loss equal to the difference between the amount of cash received and the tax basis for the Inamed Shares exchanged. The amount and character of gain or loss will be computed separately for each block of Inamed Shares that was purchased by the holder in the same transaction. Any recognized gain or loss will be capital gain or loss and any such capital gain or loss will be long term if, as of the date of sale or exchange, such stockholder has held the Inamed Shares for more than one year or will be short term if, as of such date, such stockholder has held the Inamed Shares for one year or less.
Holders who Exchange Inamed Shares Solely for Allergan Common Stock
      Holders of Inamed Shares who exchange all of their Inamed Shares solely for shares of Allergan common stock in the Offer and/or the Inamed Merger will not recognize gain or loss for United States federal income tax purposes, except with respect to cash, if any, they receive in lieu of a fractional share of Allergan common stock. Each holder’s aggregate tax basis in the Allergan common stock received in the Offer and/or the Inamed Merger will be the same as his or her aggregate tax basis in the Inamed Shares surrendered in the transaction, decreased by the amount of any tax basis allocable to any fractional share interest for which cash is received. The holding period of the Allergan common stock received in the Offer and/or the Inamed Merger by a holder of Inamed Shares will include the holding period of the Inamed Shares that he or she surrendered. If an Inamed stockholder has differing tax bases and/or holding periods in respect of the stockholder’s Inamed Shares, the stockholder should consult with a tax advisor in order to identify the tax bases and/or holding periods of the particular shares of Allergan common stock that the stockholder receives.

Table of Contents

Holders who Exchange Inamed Shares for Allergan Common Stock and Cash
      Inamed stockholders who exchange Inamed Shares for a combination of Allergan common stock and cash pursuant to the Offer and/or the Inamed Merger will recognize gain, but not loss, in the exchange. The gain, if any, recognized will equal the lesser of (a) the amount of cash received in the transaction and (b) the amount of gain realized in the transaction. The amount of gain that is realized in the exchange will equal the excess of (i) the sum of the cash plus the fair market value of the Allergan common stock received in the exchange over (ii) the tax basis of the Inamed Shares surrendered in the transaction. For this purpose, an Inamed stockholder must calculate gain or loss separately for each identifiable block of Inamed Shares that such stockholder surrenders pursuant to the transaction, and an Inamed stockholder cannot offset a loss realized on one block of such shares against a gain recognized on another block of such shares. Any gain recognized generally will be treated as capital gain, except that the stockholder’s gain could be treated as a dividend if the receipt of the cash has the effect of the distribution of a dividend for United States federal income tax purposes (under Sections 302 and 356 of the Code). The aggregate tax basis in the Allergan common stock received pursuant to the Offer and/or the Inamed Merger (including the basis in any fractional share for which cash is received) will be equal to the aggregate tax basis in the Inamed Shares surrendered in the transactions, decreased by the amount of cash received and increased by the amount of gain, if any, recognized or any amount treated as a dividend. The holding period of the Allergan common stock received in the Offer and/or the Inamed Merger by a holder of Inamed Shares will include the holding period of the Inamed Shares that he or she surrendered in exchange therefor. Cash received and gain realized in connection with the receipt of cash in lieu of a fractional share of Allergan common stock are not taken into account in making the computations of gain realized or recognized and basis in the shares received. Rather, such cash and gain are treated as described below. If an Inamed stockholder has differing tax bases and/or holding periods in respect of the stockholder’s Inamed Shares, the stockholder should consult with a tax advisor in order to identify the tax bases and/or holding periods of the particular shares of Allergan common stock that the stockholder receives.
The Receipt of Cash in Lieu of a Fractional Share
      A holder of Inamed Shares who receives cash in lieu of a fractional share of Allergan common stock will generally recognize gain or loss equal to the difference between the amount of cash received and his or her tax basis in the Allergan common stock that is allocable to the fractional share. That gain or loss generally will constitute capital gain or loss.
Consequences to Allergan and Inamed
      Neither Allergan nor Inamed will recognize gain or loss as a result of the Offer, Inamed Merger, and the Post-Closing Merger, except for any gain that might arise if Allergan pays cash or property to Inamed in connection with these transactions and such cash or property is not distributed to Inamed shareholders. Allergan does not expect any such gain to be material.
Information Reporting and Backup Withholding
      Certain U.S. holders may be subject to information reporting with respect to the cash received in exchange for Inamed Shares, including cash received instead of a fractional share interest in shares of Allergan common stock. U.S. holders who are subject to information reporting and who do not provide appropriate information when requested may also be subject to backup withholding. Any amount withheld under such rules is not an additional tax and may be refunded or credited against such U.S. holders’ federal income tax liability, provided that the required information is properly furnished in a timely manner to the Internal Revenue Service.

Purpose of the Offer; the Inamed Merger; Appraisal Rights
Purpose of the Offer; the Inamed Merger
      The purpose of the Offer is for Allergan to acquire control of, and ultimately the entire equity interest in, Inamed. The Offer, as the first step in the acquisition of Inamed, is intended to facilitate the acquisition of Inamed. The purpose of the Inamed Merger is for Allergan to acquire all outstanding Inamed Shares not tendered and purchased pursuant to the Offer. If the Offer is successful, Allergan intends to seek to consummate the Inamed Merger and Post-Closing Merger as promptly as practicable. Upon consummation of the Inamed Merger, the Surviving Corporation would become a wholly-owned subsidiary of Allergan.
      If Offeror owns 90% or more of the outstanding Inamed Shares following consummation of the Offer, Allergan intends to consummate the Inamed Merger as a “short-form” merger pursuant to Section 253 of the DGCL. In this case, neither the approval of any holder of Inamed Shares (other than Offeror) nor the approval of Inamed’s board of directors would be required. After the Offer is consummated, but prior to the completion of the Inamed Merger, Offeror may acquire additional Inamed Shares on the open market or in privately negotiated transactions to the extent required to reach the threshold of 90% ownership by Offeror of Inamed Shares, provided that any such purchases will not cause the Offer, the Inamed Merger and the Post-Closing Merger to fail to qualify as a reorganization under Section 368(a) of the Code. Any such purchases would be made at market prices or privately negotiated prices at the time of purchase, which may be higher or lower than or the same as the consideration paid per Inamed Share in the Offer.
      If Offeror owns less than 90% of the outstanding Inamed Shares following the consummation of the Offer, Allergan intends to seek to have Inamed’s board of directors submit the Inamed Merger to Inamed’s stockholders for approval in accordance with the DGCL. If the minimum tender condition described in “The Offer—Conditions of the Offer” is satisfied, Allergan will, upon consummation of the Offer, have sufficient voting power to ensure approval of the Inamed Merger without the affirmative vote of any other Inamed stockholder.
      In the Inamed Merger, each Inamed Share (except for treasury shares of Inamed and Inamed Shares beneficially owned directly or indirectly by Allergan, including Inamed Shares acquired by Offeror in the Offer) would be converted into the right to receive, at the election of the holder thereof, cash or shares of Allergan common stock, subject to proration and appraisal rights under Delaware law, as more fully described below.
      In the Inamed Merger, Inamed stockholders will have the opportunity to elect to receive the same consideration available as in the Offer, subject to proration, such that, in the aggregate, in the Inamed Merger, 45% of the aggregate Inamed Shares canceled in the Merger will be converted into cash and 55% of the aggregate Inamed Shares canceled in the Inamed Merger will be converted into shares of Allergan common stock, subject to adjustments necessary to preserve the status of the Offer, the Inamed Merger, and the Post-Closing Merger as a reorganization under Section 368(a) of the Code. If a holder of Inamed Shares has effectively demanded an appraisal of such stockholder’s Inamed Shares prior to the Inamed Merger and not withdrawn such demand or lost such rights within 30 days after the form of election and transmittal is mailed to former Inamed stockholders, such stockholder’s shares will be treated as Inamed Shares electing to receive cash in the Inamed Merger, even if the holder thereof does not subsequently perfect its rights of appraisal.
      Rule 13e-3 promulgated under the Exchange Act, which Allergan does not believe would apply to the Inamed Merger if the Inamed Merger occurs within one year of the completion of the Offer, would require, among other things, that some financial information concerning Inamed, and some information relating to the fairness of the proposed transaction and the consideration offered to stockholders of Inamed, be filed with the SEC and disclosed to stockholders prior to the completion of the Inamed Merger.
Appraisal Rights
      Although stockholders do not have appraisal rights in connection with the Offer, Inamed stockholders at the time of the Inamed Merger who do not vote in favor of the Inamed Merger will have the right under Delaware law to dissent and demand appraisal of their Inamed Shares in accordance with Section 262 of the

73


Table of Contents

DGCL. Under Section 262, dissenting Inamed stockholders who comply with the applicable statutory procedures will be entitled to receive a judicial determination of the fair value of their Inamed Shares (exclusive of any element of value arising from the accomplishment or expectation of the Inamed Merger) and to receive payment of such fair value in cash, together with a fair rate of interest, if any. In Cede & Co. and Cinerama, Inc. v. Technicolor, Inc., the Supreme Court of the State of Delaware construed Section 262 of the DGCL and held that the “accomplishment or expectation” exclusion from the calculation of fair value described in the preceding sentence is narrow and is designed to eliminate the use of pro forma data and projections of a speculative variety relating to the completion of a merger. The court held that it is appropriate to include in the calculation of fair value any known elements of value, including those elements of value that exist on the date of the merger because of a majority acquirer’s interim action in a two-step cash-out transaction. Allergan cannot assure Inamed stockholders as to the methodology a court would use to determine fair value or how a court would select which elements of value are to be included in such a determination. Any such judicial determination of the fair value of Inamed Shares could be based upon factors other than, or in addition to, the price per Inamed Share to be paid in the Inamed Merger or the market value of the Inamed Shares. The value so determined could be more or less than the price per Inamed Share to be paid in the Inamed Merger.
The Post-Closing Merger
      As soon as reasonably practicable after the Inamed Merger, Allergan will cause Inamed to merge with and into a limited liability company wholly owned by Allergan with the limited liability company surviving the merger, provided that there is no legal prohibition on completing the Post-Closing Merger.
      The Post-Closing Merger will facilitate the integration of the businesses of Allergan and Inamed. In addition, together with the Offer and the Inamed Merger, the Post-Closing Merger will have the effect of causing these transactions to qualify as a reorganization under Section 368(a) of the Internal Revenue Code. See the discussion under the caption “Material U.S. Federal Income Tax Consequences.” Immediately prior to the Post-Closing Merger, Allergan will be the sole stockholder of the Surviving Corporation, and none of the former Inamed stockholders will have any economic interest in, or approval or other rights with respect to, the Post-Closing Merger.
Plans for Inamed
      In connection with the Offer, Allergan has reviewed and will continue to review various possible business strategies that it might consider in the event that Offeror acquires control of Inamed, whether pursuant to the Offer, the Inamed Merger or otherwise. Following a review of additional information regarding Inamed, these changes could include, among other things, changes in Inamed’s business, operations, personnel, employee benefit plans, corporate structure, capitalization and management.
Divestiture of Reloxin Assets
      In July 2002, Inamed acquired the exclusive rights in the U.S., Canada and Japan to sell Beaufour Ipsen Ltd.’s botulinum toxin Type A product, branded as Reloxintm in the U.S., for all cosmetic indications. In January 2005, Inamed announced that it has entered into a preliminary agreement among Inamed, Ipsen and McGhan Limited for the rights to distribute Reloxin in other selected international markets. Inamed has announced that it currently is conducting Phase III trials for the product.
      To minimize any antitrust issues arising from the Offer and the Inamed Merger, Allergan will agree to a prompt divestiture of the Reloxin Assets, including Inamed’s license to the Reloxin products in all markets. If and to the extent needed, Allergan will seek cooperation from Beaufour Ipsen Ltd. (“Ipsen”) in this regard. Allergan also will cooperate fully with any subsequent licensee of Reloxin to ensure that the new licensee is able to benefit from studies or other work that Inamed has done in an effort to obtain regulatory approvals from the FDA or other regulatory agencies for Reloxin, including, to the extent necessary, providing the acquiring third-party all associated information, studies, reports, FDA filings and communications. Inamed and Ipsen have entered into a termination agreement pursuant to which, subject to the consummation of

74


Table of Contents

Allergan’s acquisition of Inamed and certain other conditions, all rights related to Ipsen’s Botulinum Toxin type A pharmaceutical product previously granted by Ipsen to Inamed would be returned to Ipsen, and all worldwide rights in the Reloxin® trademark would be assigned to Ipsen. Under the terms and subject to the conditions of that agreement, the return of the rights to the Botulinum Toxin type A pharmaceutical product to Ipsen, and the assignment of the worldwide rights in the Reloxin® trademark to Ipsen would be made in consideration for payment by Ipsen of ten million US dollars to Inamed.
Delisting and Termination of Registration
      If Inamed qualifies for termination of registration under the Exchange Act after the Offer is consummated, Allergan intends to seek to have Inamed withdraw the Inamed Shares from listing on the NASDAQ National Market and to terminate the registration of Inamed Shares under the Exchange Act. See “—Effect of the Offer on the Market for Inamed Shares; NASDAQ Listing; Registration Under the Exchange Act; Margin Regulations.”
Board of Directors and Management
      Upon consummation of the Inamed Merger, the directors of Inamed as the Surviving Corporation will be the directors of Offeror immediately prior to the effective time of the Inamed Merger, and the officers of Inamed as the Surviving Corporation will be the officers of Offeror immediately prior to the effective time of the Inamed Merger. After Allergan’s review of Inamed and its corporate structure, management and personnel, Allergan will determine what additional changes, if any, would be desirable.
Effect of the Offer on the Market for Inamed Shares; NASDAQ Listing; Registration Under the Exchange Act; Margin Regulations
Effect of the Offer on the Market for the Inamed Shares
      According to Inamed’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004, there were 295 holders of record of Inamed Shares as of March 10, 2005. The purchase of Inamed Shares by Offeror pursuant to the Offer will reduce the number of holders of Inamed Shares and the number of Inamed Shares that might otherwise trade publicly and could adversely affect the liquidity and market value of the remaining Inamed Shares held by the public. The extent of the public market for Inamed Shares after consummation of the Offer and the availability of quotations for such shares will depend upon a number of factors, including the number of stockholders holding Inamed Shares, the aggregate market value of the Inamed Shares held by the public at such time, the interest of maintaining a market in the Inamed Shares and analyst coverage of Inamed on the part of any securities firms and other factors.
NASDAQ Quotation
      The Inamed Shares are quoted on the NASDAQ National Market. Depending upon the number of Inamed Shares acquired pursuant to the Offer and the aggregate market value of any Inamed Shares not purchased pursuant to the Offer, Inamed Shares may no longer meet the standards for continued listing on the NASDAQ National Market and may be delisted from the NASDAQ. The published guidelines of the NASDAQ National Market state that it would consider delisting shares of a company listed on the NASDAQ National Market if, among other things, the number of round lot holders of such shares falls below 400, the number of publicly held shares falls below 750,000 or the market value of publicly held shares falls below $5,000,000. If Inamed Shares are delisted from the NASDAQ National Market, the market for Inamed Shares would be adversely affected as described above. If Inamed Shares are not delisted prior to the Inamed Merger, then Allergan intends to delist the Inamed Shares from the NASDAQ National Market promptly following consummation of the Inamed Merger.
Registration Under the Exchange Act
      Inamed Shares currently are registered under the Exchange Act. This registration may be terminated upon application by Inamed to the SEC if Inamed Shares are not listed on a national securities exchange and

75


Table of Contents

there are fewer than 300 record holders. Termination of registration would substantially reduce the information required to be furnished by Inamed to holders of Inamed Shares and to the SEC and would make certain provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b), the requirement of furnishing a proxy statement in connection with stockholders’ meetings and the requirements of Exchange Act Rule 13e-3 with respect to “going private” transactions, no longer applicable to Inamed Shares. In addition, “affiliates” of Inamed and persons holding “restricted securities” of Inamed may be deprived of the ability to dispose of these securities pursuant to Rule 144 under the Securities Act. If registration of Inamed Shares under the Exchange Act is not terminated prior to the Inamed Merger, then Allergan intends to terminate the registration of Inamed Shares following consummation of the Inamed Merger.
Margin Regulations
      Inamed Shares currently are a “margin security” under the regulations of the Board of Governors of the Federal Reserve System, which has the effect, among other things, of allowing brokers to extend credit on the collateral of the Inamed Shares. Depending upon factors similar to those described above regarding listing and market quotations, it is possible that, following the Offer, Inamed Shares may no longer constitute “margin securities” for purposes of the margin regulations of the Federal Reserve Board, in which event such Inamed Shares could no longer be used as collateral for loans made by brokers.
Dividends and Distributions by Inamed
      If on or after the date of the Allergan Merger Agreement, Inamed:
  splits, combines or otherwise changes its shares of common stock or its capitalization;
 
  acquires shares of its common stock or otherwise causes a reduction in the number of outstanding shares;
 
  pays any dividend;
 
  issues or sells any additional shares of its common stock (other than shares issued pursuant to and in accordance with the terms in effect on the date of this prospectus of employee stock options outstanding prior to such date), shares of any other class or series of capital stock, other voting securities or any securities convertible into, or options, rights, or warrants, conditional or otherwise, to acquire, any of the foregoing; or
 
  discloses that it has taken such action,
then, without prejudice to Offeror’s rights under “—Extension, Termination and Amendment” and “—Conditions of the Offer,” Offeror may, in its sole discretion, make such adjustments in the Offer consideration and other terms of the Offer and the Inamed Merger as it deems appropriate including, without limitation, the number or type of securities to be purchased.
Certain Legal Matters; Regulatory Approvals
General
      Allergan is not aware of any governmental license or regulatory permit that appears to be material to Inamed’s business that might be adversely affected by Offeror’s acquisition of Inamed Shares pursuant to the Offer or, except as described below, of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for Offeror’s acquisition or ownership of Inamed Shares pursuant to the Offer. Should any of these approvals or other actions be required, Allergan and Offeror currently contemplate that these approvals or other actions will be sought. There can be no assurance that (a) any of these approvals or other actions, if needed, will be obtained (with or without substantial conditions), or (b) if these approvals were not obtained or these other actions were not taken adverse consequences would not result to Inamed’s business, or (c) certain parts of Inamed’s or Allergan’s, or any of their respective subsidiaries’, businesses, other than that relating to the Reloxin Assets, would not have to

76


Table of Contents

be disposed of or held separate, any of which could cause Offeror to elect to terminate the Offer without the exchange of Inamed Shares under the Offer. Offeror’s obligation under the Offer to accept for exchange and pay for Inamed Shares is subject to certain conditions. See “—Conditions of the Offer.”
Antitrust
      Under the HSR Act and the rules that have been promulgated thereunder by the FTC certain acquisition transactions may not be consummated unless certain information has been furnished to the FTC and certain waiting period requirements have been satisfied. The purchase of Inamed Shares pursuant to the Offer is subject to such requirements.
      Pursuant to the requirements of the HSR Act, Allergan filed a Notification and Report Form with respect to the Offer and the Inamed Merger with and the FTC on November 15, 2005. On December 15, 2005, Allergan received a request for additional information and documentary material, referred to as a second request, from the FTC, pursuant to the HSR Act, in connection with the Offer and the Inamed Merger. Allergan has had discussions with the staff of the FTC and currently is working, in conjunction with the staff of the FTC, to develop a mutually satisfactory plan for divestiture of Inamed’s rights to the Reloxin Assets. As a result, Allergan had anticipated the issuance of the second request as part of that process. Based on its discussions with the staff at the FTC, Allergan does not anticipate that the consummation of the Offer will be materially delayed by the Reloxin divestiture process, including as a result of the second request, or by any related FTC proceedings, however there can be no assurance that the consummation of the Offer will not be materially delayed, if permitted at all, by an FTC proceeding or proceedings of antitrust authorities in foreign jurisdictions. Under the provisions of the HSR Act applicable to the Offer, the acquisition of Inamed Shares pursuant to the Offer may be completed following the expiration of a 30-calendar day waiting period (if the thirtieth day falls on a weekend or holiday, the waiting period will expire on the next business day) following the filing by Allergan with respect to the Offer, unless Allergan receives a request for additional information and documentary material from the FTC. Because, within the initial 30-day waiting period, the FTC requested additional information and documentary material from Allergan concerning the Offer, the waiting period will be extended and will expire at 11:59 p.m., New York City time, on the thirtieth calendar day after the date of substantial compliance by Allergan with that request. If the thirtieth day falls on a weekend or holiday, the waiting period will expire on the next business day. Only one extension of the waiting period pursuant to a request for additional information is authorized by the HSR Act. After that time, Allergan may close the transaction, unless Allergan agrees with the FTC to delay closing the transaction or the FTC obtains a court order staying the transaction. In practice, complying with a request for additional information or material can take a significant amount of time. The FTC may also allow Allergan to close the transaction before the expiration of the waiting period in the event that Allergan and the FTC agree on the terms of a consent order providing for the divestiture of Reloxin. If a divestiture plan can be developed that is acceptable to the FTC, the FTC will terminate its second request and will allow the transaction to close pursuant to the terms of a consent order. Allergan is currently working with the FTC staff to negotiate the terms of a divestiture plan and consent order that are acceptable to the FTC. While there can be no assurance of the outcome of these negotiations, Allergan does not anticipate that this process will result in any material delay in closing. Moreover, if the FTC raises additional substantive issues in connection with the proposed transaction, the parties will engage in negotiations with the FTC concerning possible means of addressing those issues and may agree to delay completion of the transaction while those negotiations continue. Subject to certain circumstances described in “—Extension; Termination; Amendment,” any extension of the waiting period will not give rise to any withdrawal rights not otherwise provided for by applicable law. See “—Withdrawal Rights.”
      Under the laws of certain foreign nations and multinational authorities, the transaction may not be completed or control may not be exercised unless certain filings are made with these nations’ antitrust regulatory authorities or multinational antitrust authorities, and these antitrust authorities approve or clear closing of the transaction. Other foreign nations and multinational authorities have voluntary and/or postmerger notification systems. Allergan has determined that it is required to file notifications of the Offer and Inamed Merger with the antitrust authorities in Spain and Germany. Allergan filed the requisite

77


Table of Contents

notifications in Germany on December 8, 2005 and in Spain on December 9, 2005. Should any other approval or action be required, Allergan currently contemplates that such approval or action would be sought. Although Allergan believes that it will obtain all other material required regulatory approvals in a timely manner, there can be no assurance that all other such approvals will be received in a timely manner, or at all, or that foreign or multinational antitrust authorities will not impose unfavorable conditions for granting the required approvals.
      Private parties (including individual states) may also bring legal actions under the antitrust laws. Based on an examination of the publicly available information relating to the businesses in which Inamed is engaged, Allergan does not believe that the consummation of the Offer will result in a violation of any applicable antitrust laws. However, there can be no assurance that a challenge to the Offer on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See “—Conditions of the Offer” for certain conditions to the Offer, including conditions with respect to litigation and certain governmental actions.
      In order to reduce any potential antitrust issues arising from consummation of the Offer and the Inamed Merger, Allergan will agree to an immediate divestiture of the Reloxin Assets. See “—Plans for Inamed-Divestiture of Reloxin Assets.”
Certain Relationships With Inamed
      As of the date of the Offer, Allergan beneficially owns 100 Inamed Shares, representing less than 1% of the outstanding Inamed Shares. The shares were purchased on November 8, 2005, on the NASDAQ National Market for $76.07 per Inamed Share. With the exception of the foregoing, neither Allergan nor Offeror have effected any transaction in securities of Inamed in the past 60 days. To the best of Allergan and Offeror’s knowledge, after reasonable inquiry, none of the persons listed on Annex B hereto, nor any of their respective associates or majority-owned subsidiaries, beneficially owns or has the right to acquire any securities of Inamed or has effected any transaction in securities of Inamed during the past 60 days.
      Except as described in this prospectus, (a) there have been no contracts, negotiations or transactions since November 21, 2003, between Allergan, or to the best of Allergan and Offeror’s knowledge, any of their directors, executive officers or other affiliates on the one hand, and Inamed or its affiliates on the other hand concerning any merger, consolidation, acquisition, tender offer, election of Inamed’s directors, or the sale of a material amount of Inamed’s assets, and (b) neither Allergan nor Offeror, nor to the best knowledge of Allergan or Offeror, after reasonable inquiry, none of the persons listed on Annex B hereto, nor any of their respective affiliates, have any other present or proposed material agreement, arrangement or understanding or relationship with Inamed or any of its executive officers, directors, controlling persons or subsidiaries.
Source and Amount of Funds
      The Offer and the Inamed Merger are not conditioned upon any financing arrangements or contingencies.
      Offeror estimates that the total purchase price for all of the outstanding Inamed Shares, including associated fees and expenses, will be approximately $3.4 billion, including approximately $1.6 billion in cash. Allergan has received a commitment letter from Morgan Stanley Senior Funding, Inc., an affiliate of Morgan Stanley & Co. Incorporated, providing for a 364-day bridge term facility in an aggregate amount of up to $1.1 billion. Any proceeds of this facility will be used solely to acquire Inamed Shares tendered in the Offer and pursuant to the Inamed Merger and to pay associated transaction fees and expenses.
Fees and Expenses
      Allergan has retained Morgan Stanley to act as financial advisor and dealer manager in connection with the Offer. The dealer manager may contact beneficial owners of Inamed Shares regarding the Offer and may request brokers, dealers and other nominees to forward this prospectus and related materials to beneficial owners of Inamed Shares. Allergan has agreed to pay the dealer manager a fee for its services as financial advisor and dealer manager in connection with the Offer. In addition, Allergan will reimburse the dealer manager for its reasonable out-of-pocket expenses, including the reasonable expenses and disbursements of its

78


Table of Contents

legal counsel. Allergan has also agreed to indemnify the dealer manager and its affiliates against certain liabilities in connection with its services, including liabilities under the federal securities laws.
      In the ordinary course of its businesses, the dealer manager and its affiliates may hold positions, for its own accounts or for the accounts of its customers, in the securities of Allergan and Inamed. The dealer manager or its affiliates have provided and may in the future continue to provide investment banking and other financial services, including the provision of credit facilities, for Allergan and Inamed in the ordinary course of business. In particular, Allergan has received a commitment letter from Morgan Stanley Senior Funding, Inc., an affiliate of Morgan Stanley & Co. Incorporated, providing for a 364-day bridge term facility in an aggregate amount of up to $1.1 billion as described under the section captioned “—Source and Amount of Funds.” Allergan has agreed to pay Morgan Stanley and its affiliates certain fees for such services.
      Allergan has retained MacKenzie Partners, Inc. as information agent in connection with the Offer. The information agent may contact holders of Inamed Shares by mail, email, telephone, facsimile and personal interview and may request brokers, dealers and other nominee stockholders to forward material relating to the Offer to beneficial owners of Inamed Shares. Allergan will pay the information agent reasonable and customary compensation for these services in addition to reimbursing the information agent for its reasonable out-of-pocket expenses. Allergan agreed to indemnify the information agent against certain liabilities and expenses in connection with the Offer, including certain liabilities under the U.S. federal securities laws.
      In addition, Allergan has retained Wells Fargo Bank, N.A. as exchange agent in connection with the Offer. Allergan will pay the exchange agent reasonable and customary compensation for its services in connection with the Offer, will reimburse the exchange agent for its reasonable out-of-pocket expenses and will indemnify the exchange agent against certain liabilities and expenses, including certain liabilities under the U.S. federal securities laws.
      Allergan will reimburse brokers, dealers, commercial banks and trust companies and other nominees, upon request, for customary clerical and mailing expenses incurred by them in forwarding offering materials to their customers. Except as set forth above, neither Allergan nor Offeror will pay any fees or commissions to any broker, dealer or other person for soliciting tenders of shares pursuant to the Offer.
Accounting Treatment
      The acquisition of Inamed Shares by Allergan will be accounted for under the purchase method of accounting under U.S. GAAP, which means that Inamed’s results of operations will be included with Allergan’s from the closing date of the Offer and Inamed’s consolidated assets and liabilities will be recorded at their estimated fair values at the same time (except for the minority interest, if any, in the assets and liabilities which will remain at historical cost) with the excess, if any, allocated to specific identifiable intangibles acquired, inventory, property, plant and equipment, other assets or goodwill.
Stock Exchange Listing
      Shares of Allergan common stock are listed on the New York Stock Exchange. Allergan intends to submit an application to list on the New York Stock Exchange the shares of Allergan common stock that Allergan will issue in the Offer and Inamed Merger.

      On December 15, 2003, Inamed effected a 3-for-2 stock split in the form of a 50% stock dividend (one share of common stock paid for every two shares held), paid to stockholders of record on December 1, 2003. Inamed Shares began trading at an adjusted price to reflect the stock split on December 16, 2003, and all share prices prior to this date have been restated to reflect the stock split.
      On November 18, 2005, the last full trading day prior to Allergan’s public announcement of its proposal to acquire Inamed, and December 21, 2005, the most recent practicable date prior to the date of this prospectus, the closing price of a share of Allergan common stock was $98.85 and $107.31, respectively, and the closing price of an Inamed Share was $74.44 and $87.02, respectively. Allergan encourages Inamed stockholders to obtain current market quotations for shares of Allergan common stock and Inamed Shares.
Dividends
      Allergan currently expects to pay a quarterly dividend of $0.10 per share on its common stock. Allergan’s existing and proposed debt agreements limit or are expected to limit its ability to repurchase common stock and pay dividends. Subject to these limitations, Allergan’s board of directors is free to change Allergan’s dividend practices from time to time and to decrease or increase the dividend paid, or to not pay a dividend, on Allergan’s common stock on the basis of results of operations, financial condition, cash requirements and future prospects and other factors deemed relevant by Allergan’s board of directors.

UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
      The following unaudited pro forma combined condensed statements of earnings combine the historical consolidated statements of earnings of Allergan and Inamed giving effect to the Offer and the Inamed Merger as if each had been consummated on January 1, 2004. The unaudited pro forma combined condensed balance sheet combines the historical unaudited condensed consolidated balance sheet of Allergan and the historical unaudited consolidated balance sheet of Inamed giving effect to the Offer and the Inamed Merger as if it each had been consummated on September 30, 2005.
      The allocation of purchase price in the Offer and Inamed Merger as reflected in these unaudited pro forma combined condensed financial statements has, with the assistance of independent valuation specialists, been based upon preliminary estimates of the fair value of assets acquired and liabilities assumed as of the date of the Offer and Inamed Merger. This preliminary allocation of purchase price is based on available public information and is dependent upon certain estimates and assumptions, which are preliminary and have been made solely for the purpose of developing such pro forma combined condensed financial statements.
      For the reasons mentioned in the preceding paragraph, a final determination of the fair values of Inamed’s assets and liabilities, which cannot be made prior to the completion of the transaction, will be based on the actual net tangible and intangible assets of Inamed that exist as of the date of completion of the transaction. Consequently, amounts preliminarily allocated to goodwill and identifiable intangibles could change significantly from those used in the pro forma combined condensed financial statements presented below and could result in a material change in amortization of acquired intangible assets.
      The unaudited pro forma combined condensed balance sheet does not include liabilities resulting from integration planning and adjustments to the fair value of Inamed’s reported liabilities, as these are not presently estimable. In addition to the completion of the valuation, the impact of ongoing integration activities, the timing of completion of the transaction and other changes in Inamed’s net tangible and intangible assets that occur prior to completion of the transaction could cause material differences in the information presented.
      The unaudited pro forma combined condensed financial statements are provided for informational purposes only. The unaudited pro forma combined condensed financial statements are not necessarily and should not be assumed to be an indication of the results that would have been achieved had the transaction been completed as of the dates indicated or that may be achieved in the future. Furthermore, no effect has been given in the unaudited pro forma combined condensed statements of earnings for synergistic benefits that may be realized through the combination of the two companies or the costs that may be incurred in integrating their operations. The unaudited pro forma combined condensed financial statements should be read in conjunction with the respective historical financial statements and the notes thereto of both Allergan and Inamed, which are incorporated by reference in this document. See the section entitled “Where To Obtain More Information” for more information on where you can obtain copies of these documents.
      Certain reclassifications have been made to conform Inamed’s historical amounts to Allergan’s presentation.

NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
Note 1 Basis of Presentation
      On November 15, 2005, Allergan announced an offer by its wholly owned subsidiary, Offeror, to acquire all outstanding shares of common stock of Inamed. Under the terms of the offer, stockholders of Inamed may elect to exchange each share of Inamed common stock for either $84.00 in cash or 0.8498 of a share of common stock of Allergan, such that the total value of the consideration payable will be $1.45 billion in cash and 17.9 million shares of Allergan common stock.
      Offeror’s offer was made subsequent to the execution of a merger agreement by and among Inamed and Medicis Pharmaceutical Corporation (Medicis) announced by Inamed and Medicis in March 2005. As of the date of Offeror’s offer, the merger with Medicis had not been completed. On December 13, 2005, Medicis and Inamed each announced the termination of the Medicis merger agreement pursuant to a Merger Termination Agreement.
      As of September 30, 2005 there were approximately 36.4 million shares of Inamed common stock outstanding and approximately 1.8 million Inamed shares estimated to be issuable upon exercise of outstanding options. Based on these amounts and the terms outlined above, Inamed stockholders will receive a total of approximately 17.9 million shares of Allergan common stock and $1,445.8 million in cash. The exact number of shares to be issued and exact amount of cash to be paid will depend on the number of related Inamed shares outstanding at the closing of the merger.
      The purchase price of the acquisition is approximately $3.4 billion estimated as follows (in millions):
         
Value of Allergan shares issued
  $ 1,758.0  
Cash consideration
    1,445.8  
Transaction costs (including $90 million of estimated break-up fees associated with the termination of the Medicis merger transaction)
    165.9  
       
Total
  $ 3,369.7  
       
      The allocation of the purchase price as of September 30, 2005 is summarized below (in millions):
         
Current assets
  $ 390.7  
Property, plant and equipment
    60.7  
In-process research and development
    113.4  
Assets held for sale
    10.0  
Identifiable intangible assets (including developed technology of $654.4, customer relationships of $86.4, core technology of $35.5 and other intangibles of $4.1)
    780.4  
Goodwill
    2,293.5  
Other assets (including deferred tax assets)
    28.3  
Current liabilities
    (92.2 )
Additional deferred tax liabilities
    (197.8 )
Other long-term liabilities
    (17.3 )
       
Net assets
  $ 3,369.7  
       
      The value of the Allergan shares used in determining the purchase price was $98.35 per share based on the average of the closing price of Allergan common stock for a range of four trading days, two days prior to and two days subsequent to the announcement of the offer.
      The determination of the final purchase price and allocation of the purchase price is preliminary. The final determination of the purchase price allocation will be based on the fair values of assets acquired, including fair values of acquired in-process research and development and other identifiable intangibles, and the fair value of liabilities assumed as of the date that the acquisition is consummated. The excess of the purchase price over the fair value of assets and liabilities acquired is allocated to goodwill. The purchase price allocation will remain preliminary until Allergan completes a third party valuation of significant identifiable

intangible assets acquired (including in-process research and development), evaluates integration plans to be undertaken following the consummation of the merger, and determines the fair values of other assets and liabilities acquired. The final determination of the purchase price allocation is expected to be completed as soon as practicable after the consummation of the merger. The final amounts allocated to assets and liabilities acquired could cause material differences in the information presented in the unaudited pro forma combined condensed financial statements.
      The amount allocated to acquired in-process research and development represents an estimate of the fair value of purchased in-process technology for research projects that, as of the date of expected closing of the merger, will not have reached technological feasibility and have no alternative future use. The values of the research projects will be determined based on analyses using cash flows to be generated by the products that result from the in-process projects. These cash flows will be estimated by forecasting total revenues expected from these products and then deducting appropriate operating expenses, cash flow adjustments and contributory asset returns to establish a forecast of net cash flows arising from the in-process technology. These cash flows will be substantially reduced to take into account the time value of money and the risks associated with the inherent difficulties and uncertainties given the projected stage of development of these projects at closing. For purposes of the unaudited pro forma combined condensed balance sheet as of September 30, 2005, $113.4 million of the total purchase price has been allocated to acquired in-process research and development, which includes the estimated value of Inamed’s silicone gel filled breast implant technology for use in the United States ($53.1 million) and Juvederm, a non-animal based, cross-linked hyaluronic-acid dermal filler technology for use in the United States ($60.3 million), both of which are not expected to have reached technological feasibility as of the closing date and have no alternative future use. The amounts allocated to in-process research and development will be charged to the statement of earnings in the period the acquisition is consummated.
      In connection with this transaction, Allergan expects to divest all of Inamed’s exclusive sales rights of Reloxin, a botulinum toxin Type A product that has not yet been approved for sale in the United States. Accordingly, the estimated fair value of Reloxin has been capitalized and is reflected as an asset held for sale on the unaudited pro forma combined condensed balance sheet.
Note 2 Pro Forma Adjustments
Pro Forma Statement of Earnings Adjustments
      (a)     To reclassify Inamed product warranty costs of $4.9 million for both the nine month period ended September 30, 2005 and the year ended December 31, 2004 from Selling, General and Administrative expense to Cost of Sales to conform to Allergan’s presentation.
      (b)     To eliminate $10.5 million of costs related to the Medicis merger transaction that will not have an ongoing impact on the combined operations. The elimination of these costs will not be tax affected for pro forma purposes as they were not tax affected by Inamed due to the fact that these costs are capitalizable by Inamed under current tax regulations.
      (c)     Reflects amortization of $55.8 million and $74.3 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively, for identified intangible assets based on the estimated fair values assigned to these assets at the date of acquisition and estimated useful lives of 15 years, 4 years and 16 years for developed technology, customer relationships and core technology, respectively, and the elimination of historical Inamed intangible amortization of $4.0 million and $5.0 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively. Acquired other intangible assets of $4.1 million are estimated to not be subject to amortization, consistent with Inamed’s current public disclosures. Assuming an aggregate average useful life of 15 years, straight-line amortization, and a tax rate of 25.0%, for every additional $50 million allocated to identified intangible assets, net earnings will decrease by $1.9 million and $2.5 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively.

      (d) Reflects lower interest income due to the assumed use of $575.5 million of Allergan cash and equivalents to finance a part of the cash portion of the merger consideration and transaction costs and retirement of Inamed’s notes payable balance and assumes interest rates based on Allergan’s historical average interest rate earned on cash equivalents of 3.00% and 1.50% for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively.
      (e)     Reflects higher incremental interest expense of $40.5 million and $53.6 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively, and amortization of debt issuance costs of $0.7 million and $0.9 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively, due to additional assumed borrowings of $1.045 billion at varying interest rates to finance a part of the cash portion of the merger consideration and transaction costs in excess of Allergan’s cash and equivalents available to finance the merger. Allergan expects to re-finance the 364-day bridge term facility used to initially fund a portion of the offer and merger consideration and transaction costs with senior long-term debt totaling $1.045 billion with a mix of financing maturities. For purposes of these pro forma financial statements, estimated maturities of total pro forma combined long-term debt (including long-term convertible notes) due after one year are: zero in 2006; $518.4 million in 2007; $282.2 million in 2008; zero in 2009; $250.0 million in 2010 and $570.0 million after 2010. The effect of a 0.125 percentage point variance in the interest rate on net earnings, assuming a tax rate of 38.0%, is $0.6 million and $0.8 million for the nine month period ended September 30, 2005 and the year ended December 31, 2004, respectively.
      (f)     To reclassify royalty expense of $9.9 million for the year ended December 31, 2004 from Selling, General and Administrative expense to Cost of Sales to conform to Inamed’s 2005 presentation.
      (g)     Represents the income tax effect of unaudited pro forma combined condensed statement of earnings adjustments using an estimated effective tax rate of 25.0% for adjustments to the fair value of Inamed’s net assets and an estimated combined United States federal and state statutory rate of 38.0% applied to the interest income and interest expense adjustments.
      (h)     Pro forma basic earnings per share is calculated by dividing the pro forma combined net income by the pro forma weighted average shares outstanding. Pro forma diluted earnings per share is calculated by dividing the pro forma combined net income by the pro forma weighted shares outstanding and dilutive potential weighted shares outstanding. A reconciliation of the shares used to calculate Allergan’s historical basic and diluted earnings per share to shares used to calculate the pro forma basic and diluted earnings per share follows (in millions):

      (j)     Reflects the receipt and use of assumed proceeds of additional borrowings to finance a part of the cash portion of the offer consideration and merger consideration and transaction costs.
      (k)     Reflects adjustment of the historical Inamed inventories to estimated fair value. Because this adjustment is directly attributed to the transaction and will not have an ongoing impact in excess of one year, it is not reflected in the unaudited pro forma combined condensed statements of earnings. However, this inventory adjustment will impact cost of sales subsequent to the consummation of the transaction.
      (l)     Reflects the use of Allergan cash and equivalents to retire Inamed’s notes payable balance.
      (m)     Reflects the portion of the purchase price allocated to Inamed’s exclusive sales rights of Reloxin, a botulinum toxin Type A product that has not yet been approved for sale in the United States, which will be divested by Allergan immediately after the completion of the merger.
      (n)     Reflects the portion of the purchase price allocated to acquired intangible assets, including developed technology of $654.4 million, customer relationships of $86.4 million, core technology of $35.5 million and other intangibles of $4.1 million, less Inamed’s historical net intangible assets of $47.9 million. The amount of intangible assets is subject to change and will be finalized upon consummation of the transaction and completion of an evaluation.
      (o)     Reflects the portion of the purchase price allocated to acquired in-process research and development projects that, as of the closing date of the merger, will not have reached technical feasibility and have no alternative future use. The preliminary estimate of the fair value of acquired in-process research and development is $113.4 million. The amount of acquired in-process research and development is subject to change and will be finalized upon consummation of the transaction and completion of an evaluation. Because this expense is directly attributable to the acquisition and will not have a continuing impact in excess of one year, it is not reflected in the unaudited pro forma combined condensed statements of earnings. However, this item will be recorded as an expense in the period that the acquisition is completed. For every incremental $10.0 million increase to the amount allocated to acquired in-process research and development, there will be a $10.0 million decrease to net income in the period in which the transaction occurs. Additionally, goodwill will also decrease by $10.0 million.
      (p)     Reflects the use of cash and equivalents to pay estimated break-up costs associated with the terminated Medicis merger ($90.0 million) and estimated transaction costs ($75.9 million). Estimated transaction costs consist primarily of investment banker fees, legal and professional fees, severance costs and debt issuance costs. Estimated debt issuance costs of $5.9 million are reflected in Investments and other assets in the unaudited pro forma combined condensed balance sheet.
      (q)     The adjustment to goodwill reflects the elimination of historical Inamed goodwill of $136.3 million and the addition of goodwill from the purchase price allocation of $2,293.5 million.

DESCRIPTION OF ALLERGAN CAPITAL STOCK
      Allergan’s authorized capital stock consists of 300,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share. As of October 28, 2005, there were 134,254,772 shares of Allergan common stock outstanding (including 2,646,927 shares held in treasury) and held of record by approximately 6,038 stockholders, and no shares of preferred stock were outstanding. On such date, 12,025,235 shares of common stock were subject to outstanding options.
      The following description of the terms of the common stock and preferred stock of Allergan is not complete and is qualified in its entirety by reference to Allergan’s Restated Certificate of Incorporation, as amended, and its Bylaws, each of which are filed as an exhibit to the registration statement of which this prospectus is a part. To find out where copies of these documents can be obtained, see “Where to Obtain More Information.”
Common Stock
      Holders of Allergan’s common stock are entitled to receive dividends declared by the board of directors, out of funds legally available for the payment of dividends, subject to the rights of holders of preferred stock. For the past three fiscal quarters, Allergan has paid a dividend of $0.10 per share per quarter, increased from $0.09 paid per quarter, in each of the prior eight quarters. Each holder of Allergan common stock is entitled to one vote per share. Upon any liquidation, dissolution or winding-up of its business, the holders of Allergan common stock are entitled to share equally in all assets available for distribution after payment of all liabilities and provision for liquidation preference of any shares of preferred stock then outstanding. The holders of Allergan common stock have no preemptive rights and no rights to convert their common stock into any other securities. There are also no redemption or sinking fund provisions applicable to the Allergan common stock.
      Allergan’s common stock is listed on the New York Stock Exchange under the symbol “AGN.” The transfer agent and registrar for the common stock is Wells Fargo Bank, N.A
Preferred Stock
      Allergan’s board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of Allergan preferred stock in one or more series and to fix the following terms of the preferred stock:
  designations, powers, preferences, privileges;
 
  relative participating, optional or special rights; and
 
  the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences.
      Any or all of these rights may be greater than the rights of the Allergan common stock. Allergan’s board of directors has designated 1,500,000 shares of preferred stock “Series A Junior Participating Preferred Stock,” which shares are issuable upon certain events specified in Allergan’s rights plan, as described below.
      Allergan’s board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could negatively affect the voting power and other rights of the holders of common stock. Preferred stock could thus be issued quickly with terms calculated to delay or prevent a change in control of Allergan or make it more difficult to remove Allergan’s management. Additionally, the issuance of Allergan preferred stock may have the effect of decreasing the market price of Allergan’s common stock.
Rights Plan
      On January 25, 2000, Allergan’s board of directors declared a dividend of one preferred stock purchase right for each share of common stock, par value $0.01 per share, outstanding as of the close of business on February 18, 2000, the record date. As long as the rights are attached to Allergan’s common stock, Allergan will issue one right (subject to adjustment) with each new share of Allergan common stock so that all shares

90


Table of Contents

of Allergan common stock will have attached rights. When exercisable, each right will entitle the registered holder to purchase from Allergan one one-hundredth of a share of Series A Junior Participating Preferred Stock at a price of $300.00 per one one-hundredth of a share of Series A Junior Participating Preferred Stock, subject to adjustment. Until a right is exercised, the holder of the right has no right to vote or receive dividends or any other rights as a stockholder as a result of holding the right. The rights trade automatically with shares of Allergan common stock and may only be exercised in connection with certain attempts to takeover Allergan. The rights are designed to protect the interests of Allergan and its stockholders against coercive takeover tactics and to encourage potential acquirors to negotiate with its board of directors before attempting a takeover. The preferred stock purchase rights theoretically could, but are not intended to, deter takeover proposals that might be in the best interests of Allergan’s stockholders.
      The description and terms of the preferred stock purchase rights set forth above is not complete and is qualified in its entirety by reference to the rights agreement, dated as of January 25, 2000, between Allergan and Wells Fargo Bank, N.A. (as successor rights agent to EquiServe Trust Company, N.A. and First Chicago Trust Company of New York), as amended January 2, 2002, January 30, 2003 and October 19, 2005, and as may be amended further from time to time. The rights expire on February 18, 2010.

  at or subsequent to such time, the business combination is approved by Allergan’s board of directors and authorized at an annual or special meeting of Allergan’s stockholders, and not by written consent, by the affirmative vote of at least 662/3% of the outstanding voting stock that is not owned by the interested stockholder.
      Under Section 203, a “business combination” includes:
  any merger or consolidation involving the corporation and the interested stockholder;
 
  any sale, transfer, pledge or other disposition of 10% or more of a corporation’s assets involving the interested stockholder;
 
  any transaction that results in the issuance or transfer by the corporation of any of its stock to the interested stockholder, subject to limited exceptions;
 
  any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation’s capital stock beneficially owned by the interested stockholder; or
 
  the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
      In general, Section 203 defines an “interested stockholder” as any entity or person beneficially owning 15% or more of the outstanding Allergan voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

Restated Certificate of Incorporation and Bylaw Provisions
      Various provisions contained in Allergan’s restated certificate of incorporation and bylaws could delay or discourage some transactions involving an actual or potential change in control of Allergan or its management and may limit the ability of Allergan stockholders to remove current management or approve transactions that Allergan stockholders may deem to be in their best interests.

  authorize Allergan’s board of directors to establish one or more series of undesignated preferred stock, the terms of which can be determined by the board of directors at the time of issuance;
 
  divide Allergan’s board into three classes of directors, with each class serving a staggered three-year term;
 
  require that any action required or permitted to be taken by Allergan’s stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing;
 
  provide an advanced written notice procedure with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of Allergan’s board of directors or a committee of its board of directors;
 
  state that special meetings of Allergan’s stockholders may be called only by the chairman of its board of directors, its board of directors itself or its president;

  allow Allergan’s directors, and not its stockholders, to fill vacancies on its board of directors, including vacancies resulting from removal or enlargement of the board.

Indemnification of Directors, Officers and Employees   Allergan will indemnify, to the fullest extent permitted by law, its directors and officers in connection with proceedings to which they are made parties by reason of the fact that they are or were directors or officers of Allergan; provided, however, that Allergan is not required to indemnify a director or officer in connection with a proceeding commenced by such director or officer unless the proceeding was authorized by the board of directors.

The DGCL allows the above indemnification only if the director or officer acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of Allergan, and, in the case of a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In suits by Allergan, and derivative suits by stockholders of Allergan, against directors or officers of Allergan, Delaware law does not allow indemnification without judicial approval if the officer or director is adjudged to be liable to Allergan.

Allergan will advance expenses (including attorneys’ fees) before the final disposition of any proceeding upon receipt of an undertaking by the director or officer to repay such amount if it is ultimately determined that he or she is not entitled to be indemnified by Allergan.
  Inamed’s bylaws provide that it will indemnify, to the fullest extent permitted by law, its directors in connection with proceedings to which they are made parties by reason of the fact that they are or were directors, officers, employees or agents of Inamed, provided, however, that Inamed is not required to indemnify an entity in connection with a proceeding commenced by such director or officer unless the proceeding was authorized by (i) the board of directors, (ii) independent legal counsel in a written opinion, or (iii) the stockholders.

The DGCL allows the above indemnification only if the agent acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of Inamed, and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful. In suits by Inamed, and derivative suits by stockholders of Inamed, against directors or officers of Inamed, Delaware law does not allow indemnification without judicial approval if the officer or director is adjudged to be liable to Inamed.

Inamed’s certificate of incorporation provides that it will advance reasonable expenses before the final disposition of any proceeding if the agent undertakes to repay such amount if it is determined that they are not entitled to indemnification, except that such advances will no be made if the board of directors or an independent legal counsel determines that such an agent is not entitled to indemnification.
 
Anti-Takeover Provisions:        
 
Business Combination Act   Allergan is subject to Section 203 of the DGCL, which prohibits specified business combinations by an interested stockholder (defined as a holder of 15% or more of the outstanding voting shares of a corporation) for a period of three years after the stockholder becomes an interested stockholder unless

    stockholder, the board of directors approves the business combination or the transaction by which the stockholder becomes an interested stockholder,

•   upon completion of the transaction by which the stockholder becomes an interested stockholder, the stockholder owns at least 85% of the voting stock of the corporation (excluding shares owned by directors who are also officers and by certain employee stock ownership plans) or

•   on or after the date the stockholder becomes an interested stockholder, the business combination receives the approval of both the directors and the holders of at least two-thirds of the outstanding voting shares not owned by the interested stockholder.

A Delaware corporation may opt out of Section 203 through an amendment to its certificate of incorporation or bylaws adopted by a majority of the outstanding voting shares, provided that, in most cases, such an amendment will not become effective until 12 months after its adoption and will not apply to any person who became an interested stockholder on or prior to its adoption.

Allergan has not adopted any such charter or bylaw amendment. Allergan’s certificate of incorporation defines an interested stockholder as one who becomes a holder of 5% or more of Allergan’s voting shares. Allergan’s certificate of incorporation requires that any transaction with such an interested stockholder be approved by at least 662/3% of the outstanding voting securities.

The following description of the rights agreement, as amended, is subject in its entirety to the terms and conditions of the rights agreement. You should read the rights agreement carefully, a copy of which is incorporated into the registration statement, of which this prospectus is a part. See “Where to Obtain More Information.”

Pursuant to the rights agreement, one right is attached to each share of Allergan common stock outstanding.

Until a right is exercised, the holder thereof, as such, will have no rights as a stockholder of Allergan beyond those as an existing stockholder, including, without limitation, the right to vote or to receive dividends.

Exercisability of Rights. The rights become exercisable and transferable separately from Allergan common stock upon the earlier of:

•   ten days following a public announcement that a person or group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of Allergan common stock, with certain exceptions, or

•   ten business days (or such later date as may be determined by action of the board of directors under certain conditions) following the commencement or announcement of an intention to make a tender offer or exchange offer, the consummation of which would result in the beneficial ownership by a person or group of 15% or more of Allergan common stock, with certain exceptions.

Each right will entitle the holder to purchase 1/100th shares of Series A
  dated as of November 16, 1999, as amended by Amendment No. 1 dated as of December 22, 1999, Amendment No. 2 dated as of April 1, 2002, Amendment No. 3 dated as of March 20, 2005 and Amendment No. 4 dated December 20, 2005. The following description of the rights agreement, as amended, is subject in its entirety to the terms and conditions of the rights agreement. You should read the rights agreement carefully. See “Where to Obtain More Information.”

As disclosed by Inamed in an amendment to its Form 8-A relating to Inamed’s rights plan filed by Inamed with the SEC on December 21, 2005, on December 20, 2005, Inamed entered into Amendment No. 4 to the rights agreement, which excludes the Offer, the Inamed Merger and the Second Merger from the scope of the rights agreement and provides for the termination of the rights agreement and the rights issued thereunder immediately prior to the effective time of the Inamed Merger. Accordingly, the rights agreement does not apply to these transactions.

Pursuant to the rights agreement, one right is attached to each share of Inamed common stock outstanding.

Exercisability of Rights. The rights become exercisable and transferable separately from Inamed common stock upon the earlier of:

•   ten days after a person or group has acquired beneficial ownership of 15% or more of Inamed’s outstanding common stock, with certain exceptions; or

“Flip-In” Feature. With certain exceptions, in the event that a person acquires 15% or more of Allergan’s common stock, or if Allergan were the surviving corporation in a merger with such a person or any affiliate or associate of such a person, and the shares of Allergan common stock were not changed or exchanged, each holder of a right, other than rights that are or were acquired or beneficially owned by the acquiring person (which rights will thereafter be void), will thereafter have the

Redemption of Rights. Inamed may redeem the rights in whole at a price of $.01 per right at any time before the close of business on the tenth business day after a person or group obtains 15% or more of Inamed’s outstanding common stock.

Amendment of Rights Agreement.

ALLERGAN’S EXISTING DEBT AGREEMENTS
Zero Coupon Convertible Senior Notes
      On November 6, 2002, Allergan issued zero coupon convertible senior notes due 2022, or “Senior Notes,” in a private placement. The Senior Notes:
  represent Allergan’s unsecured senior obligations and rank equally with all of its other unsecured senior indebtedness and are junior to all of its current and future secured indebtedness;
 
  have a $641,510,000 aggregate principal amount at maturity;
 
  accrue interest at 1.25% annually;
 
  will mature on November 6, 2022;
 
  were issued at a discount of $141.5 million; and
 
  are convertible under certain circumstances into 11.41 shares of Allergan’s common stock for each $1,000 principal amount at maturity.
      The Senior Notes are convertible:
  if the closing price of Allergan’s common stock exceeds certain levels;
 
  the credit ratings assigned to the Senior Notes are reduced below specified levels; or
 
  Allergan calls the Senior Notes for redemption, makes specified distributions to its stockholders or becomes a party to certain consolidation, merger or binding share exchange agreements.
      Based on the terms of the Senior Notes, an assessment of the conversion criteria is performed each fiscal quarter, the result of which affects the holders’ ability to convert the Senior Notes in the immediately succeeding fiscal quarter. As of September 30, 2005, the conversion criteria had been met and holders may elect to convert the Senior Notes into shares of Allergan common stock between October 1, 2005 and December 31, 2005. Allergan does not currently expect any of the holders of the Senior Notes to elect conversion during its fourth fiscal quarter of 2005. If the conversion criteria are not met in the fiscal quarter ending December 31, 2005, the holders’ ability to convert the Senior Notes will be restricted until the conversion criteria are again met.
      On July 28, 2004, Allergan, together with Wells Fargo Bank, as trustee, executed a supplemental indenture to the indenture governing the Senior Notes. The supplemental indenture amends the indenture’s redemption and conversion provisions to restrict Allergan’s ability to issue common stock in lieu of cash to holders of the Senior Notes upon any redemption or conversion. Upon any redemption, Allergan is now required to pay the entire redemption amount in cash. In addition, upon any conversion, Allergan will pay cash up to the accreted value of the Senior Notes converted and will have the option to pay any amounts due in excess of the accreted value in either cash or common stock.
      Holders of the Senior Notes may require Allergan to purchase the Senior Notes on any of the following dates at the following prices:
  $829.51 per Senior Note on November 6, 2007;
 
  $882.84 per Senior Note on November 6, 2012; and
 
  $939.60 per Senior Note on November 6, 2017.
      In addition, holders of the Senior Notes may require Allergan to purchase the Senior Notes upon a Fundamental Change (as defined in the indenture governing the Senior Notes, as amended) prior to November 6, 2007.
      Pursuant to the supplemental indenture, Allergan is required to pay cash for any Senior Notes purchased by it on any of these three dates. Allergan was restricted from redeeming the Senior Notes before

Table of Contents

November 6, 2005. Prior to November 6, 2007, Allergan may redeem all or a portion of Senior Notes for cash in an amount equal to their accreted value only if the price of its common stock reaches certain thresholds for a specified period of time. On or after November 6, 2007, Allergan may redeem all or a portion of the Senior Notes for cash in an amount equal to their accreted value.
Notes Payable and Other Long-Term Debt
      Allergan has a committed long-term credit facility, a committed foreign line of credit in Japan, a commercial paper program, a medium term note program, an unused debt shelf registration statement that may be used for a new medium term note program and other issuances of debt securities, and various foreign bank facilities.
  The committed credit facility allows for borrowings of up to $400 million through May 2009.
 
  The committed foreign line of credit allows for borrowings of up to three billion Japanese yen (approximately $26.4 million) through July 2006.
 
  The commercial paper program provides for up to $300 million in borrowings.
 
  The medium term note program allows Allergan to issue up to an additional $8.0 million in registered notes on a non-revolving basis.
 
  The debt shelf registration statement provides for up to $350 million in additional debt securities.
 
  Borrowings under the long-term credit facility and medium-term note program are subject to certain financial and operating covenants that include, among other provisions, maintaining minimum debt to capitalization ratios and a minimum consolidated net worth. Certain covenants also limit subsidiary debt and restrict dividend payments. Allergan is in compliance with these covenants.
      As of September 30, 2005, Allergan had $120.0 million outstanding in borrowings under its committed credit facility, $6.0 million in borrowings under various foreign bank loans, $57.2 million in borrowings under the medium term note program and no borrowings outstanding under its commercial paper program or committed foreign line of credit.
      Allergan does not currently intend to have combined borrowings under its committed credit facilities and its commercial paper program that would exceed $300 million in the aggregate.

      NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement and intending to be legally bound hereby, the parties hereto agree as follows:
ARTICLE I
THE OFFER
      Section 1.01.     The Offer.
      (a) On November 21, 2005, Parent caused Merger Sub to commence (within the meaning of Rule 14d-2 promulgated under the Exchange Act) the Offer. In the Offer, each Share accepted by Merger Sub in accordance with the terms and subject to the conditions of the Offer shall be exchanged for the right to receive from Merger Sub, at the election of the holder: (i) $84.00 in cash, without interest (the Cash Consideration), or (ii) 0.8498 of a share of common stock, par value $0.01 per share, of Parent (together with the Parent Rights, as defined in Section 3.01(f), the Parent Stock, and such fraction of a share of Parent Stock issuable in exchange for each Share pursuant to the Offer, the Parent Stock Consideration), with cash in respect of fractional shares of Parent Stock in accordance with Section 1.01(f), and in each case subject to proration as set forth in Section 1.01(d).
      (b) The obligation of Merger Sub to accept for payment or exchange, and to pay for or exchange Shares pursuant to the Offer, shall be subject only to the Minimum Condition (as defined in Annex A hereto) and to the other conditions set forth in Annex A attached hereto. Merger Sub expressly reserves the right to increase the consideration payable pursuant to the Offer and to waive any condition of the Offer, provided that the conditions described in clauses (c)(i) and (d)(i)—(iii) of Annex A attached shall not be waivable. Subject to the extension rights described in subparagraph (h) below, Merger Sub shall, and Parent shall cause Merger Sub to, accept for payment or exchange, all Shares which have been validly tendered and not withdrawn pursuant to the Offer at the earliest time following the Expiration Date (as defined in subparagraph (h)) at which all conditions to the Offer shall have been satisfied or waived by Merger Sub, and Merger Sub shall not otherwise extend the Offer. The Company agrees that no Shares held by the Company or any of its Subsidiaries will be tendered in the Offer. Without the consent of the Company, Merger Sub shall not (i) reduce the number of Shares subject to the Offer, (ii) reduce the Cash Consideration or Parent Stock Consideration, (iii) waive or change the Minimum Condition, (iv) add to the conditions set forth in Annex A, (v) modify any condition set forth in Annex A or amend any term of the Offer set forth in this Agreement, in each case, in any manner materially adverse to the holders of Shares, or (vi) change the form of consideration.
      (c) Subject to Sections 1.01(d), (e) and (f), each holder of Shares shall be entitled to elect (i) the number of Shares which such holder desires to exchange for the right to receive the Cash Consideration (a Cash Election), and (ii) the number of Shares which such holder desires to exchange for the right to receive Parent Stock Consideration (a Parent Stock Election). Any Cash Election or Parent Stock Election shall be referred to herein as an Election,” and shall be made on a form furnished by Merger Sub for that purpose (a Form of Election), included as part of the letter of election and transmittal accompanying the Offer. Holders of record who hold Shares as nominees, trustees or in other representative capacities may submit multiple Forms of Election on behalf of their respective beneficial holders.
      (d) The maximum aggregate amount of cash payable pursuant to the Offer shall be (x) $84.00 multiplied by (y) 45% of the total number of Shares outstanding that are tendered and accepted for purchase pursuant to the Offer (such amount, the Maximum Cash Consideration). The maximum aggregate amount of Parent Stock Consideration issuable pursuant to the Offer shall be (x) 0.8498 shares of Parent Stock multiplied by (y) 55% of the total number of Shares outstanding that are tendered and accepted for exchange pursuant to the Offer (such amount or any lesser amount specified in accordance with Section 1.01(e) being referred to as the Maximum Parent Stock Consideration).
        (i) If the total number of Cash Elections would require aggregate cash payments in excess of the Maximum Cash Consideration, such Elections shall be subject to proration as follows. For each Cash Election, the number of Shares that shall be converted into the right to receive the Cash Consideration shall be (A) the total number of Shares subject to such Cash Election multiplied by (B) the Cash

A-2

  Proration Factor, rounded down to the nearest Share. The Cash Proration Factor means a fraction (x) the numerator of which shall be the Maximum Cash Consideration and (y) the denominator of which shall be the product of the aggregate number of Shares subject to all Cash Elections made by all holders of Shares, multiplied by the Cash Consideration. All Shares subject to a Cash Election, other than Shares converted into the right to receive the Cash Consideration in accordance with this Section 1.01(d), shall be converted into the right to receive the Parent Stock Consideration. All prorations resulting from this Section 1.01(d) shall be applied on a pro rata basis, such that each Company stockholder who tenders Shares subject to a Cash Election bears its proportionate share of the proration, based on the percentage of the total Shares tendered subject to a Cash Election tendered by such Company stockholder.
 
        (ii) If the total number of Parent Stock Elections would require the issuance in the aggregate of a number of shares of Parent Stock in excess of the Maximum Parent Stock Consideration, such Elections shall be subject to proration as follows. For each Parent Stock Election, the number of Shares that shall be converted into the right to receive the Parent Stock Consideration shall be (i) the total number of Shares subject to such Parent Stock Election multiplied by (ii) the Parent Stock Proration Factor, rounded down to the nearest Share. The Parent Stock Proration Factor means a fraction (x) the numerator of which shall be the Maximum Parent Stock Consideration and (y) the denominator of which shall be the product of the aggregate number of Shares subject to all Parent Stock Elections made by all holders of Shares, multiplied by the Parent Stock Consideration. All Shares subject to a Parent Stock Election, other than that number converted into the right to receive the Parent Stock Consideration in accordance with this Section 1.01(d), shall be converted into the right to receive the Cash Consideration. All prorations resulting from this Section 1.01(d) shall be applied on a pro rata basis, such that each Company stockholder who tenders subject to a Parent Stock Election bears its proportionate share of the proration, based on the percentage of the total Shares tendered subject to a Parent Stock Election tendered by such Company stockholder.
      (e) Each Share validly tendered but which is not the subject of a valid Election shall be deemed to be tendered subject to the following Elections:
        (i) If the Cash Elections exceed the Maximum Cash Consideration such that proration of Cash Elections occur, Shares validly tendered without a valid Election will be deemed tendered subject to a Parent Stock Election;
 
        (ii) If the Parent Stock Elections exceed the Maximum Parent Stock Consideration such that proration of Parent Stock Elections occurs, Shares validly tendered without a valid Election will be deemed tendered subject to a Cash Election; and
 
        (iii) If no proration occurs, Shares validly tendered without a valid Election will be deemed tendered in part subject to a Cash Election and in part subject to a Parent Stock Election to the extent of the Cash Consideration and Parent Stock Consideration remaining after taking into account the Cash Elections and Stock Elections made by those Company stockholders who affirmatively made Elections in the Offer. The remaining available Cash Consideration and Parent Stock Consideration will be allocated on a pro rata basis among the Shares tendered by those Company stockholders who validly tendered Shares but did not specify an Election, such that each such Share is exchanged for the same proportion of Cash Consideration and Parent Stock Consideration, based on the respective percentages of available Cash Consideration and Parent Stock Consideration remaining after taking into account the affirmative Elections of the tendering Company stockholders.
      (f) In lieu of any fractional share of Parent Stock that otherwise would be issuable pursuant to the Offer, each holder of Shares who otherwise would be entitled to receive a fraction of a share of Parent Stock pursuant to the Offer will be paid an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the Exchange Agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Parent Stock issued pursuant to the Offer. As soon as practicable following the completion of the Offer, the Exchange Agent shall determine the excess of (i) the number of whole shares of Parent Stock issuable to the former holders of Shares pursuant to

A-3


Table of Contents

the Offer including fractional shares, over (ii) the aggregate number of whole shares of Parent Stock to be distributed to former holders of Shares (such excess being collectively called the Excess Offer Parent Stock). The Exchange Agent, as agent and trustee for the former holders of Shares, shall as promptly as reasonably practicable sell the Excess Offer Parent Stock at the prevailing prices on the NYSE. The sales of the Excess Offer Parent Stock by the Exchange Agent shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. Parent shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent and costs associated with calculating and distributing the respective cash amounts payable to the applicable former holders of Shares, incurred in connection with such sales of Excess Offer Parent Stock. Until the proceeds of such sales have been distributed to the former holders of Shares to whom fractional shares of Parent Stock otherwise would have been issued in the Offer, the Exchange Agent will hold such proceeds in trust for such former holders. As soon as practicable after the determination of the amount of cash to be paid to former holders of Shares in respect of any fractional shares of Parent Stock, the Exchange Agent shall distribute such amounts to such former holders.
      (g) If, between the date of this Agreement and the completion of the Offer, the outstanding shares of Parent Stock or the Shares shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Cash Consideration, the Parent Stock Consideration, the Maximum Cash Consideration, the Maximum Parent Stock Consideration, the Cash Proration Factor and the Parent Stock Proration Factor shall be correspondingly adjusted as appropriate to provide the holders of Shares tendered pursuant to the Offer the same economic effect as contemplated by this Agreement prior to such event.
      (h) Subject to the terms and conditions thereof, the Offer shall remain open until at least 5:00 p.m., New York City time, on January 9, 2006 (the Expiration Date,” unless extended, in which case any expiration time and date established pursuant to an authorized extension of the Offer, the Expiration Date); provided, however, that Merger Sub:
        (i) shall, and Parent shall cause Merger Sub to, from time to time extend the Offer, in increments of no more than ten (10) Business Days each, if at the initial or any subsequent scheduled Expiration Date any of the conditions of the Offer shall not have been satisfied or waived, until such time as such conditions are satisfied or waived to the extent permitted by this Agreement;
 
        (ii) shall, and Parent shall cause Merger Sub to, extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer; and
 
        (iii) may extend the Offer one time only for up to five (5) Business Days if less than 90% of the total Shares on a fully diluted basis have been validly tendered and not properly withdrawn at the otherwise scheduled Expiration Date.
In each of the above cases, Parent shall cause Merger Sub to extend the Offer from time to time in accordance with this Section 1.1(h) for the shortest time periods which it reasonably believes are necessary until consummation of the Offer if the conditions of the Offer shall not have been satisfied or waived, so long as this Agreement shall not have been terminated in accordance with Article VIII hereof.
      (i) As promptly as practicable after the date of this Agreement, Parent and Merger Sub shall (i) amend or supplement (x) the Tender Offer Statement on Schedule TO with respect to the Offer (together with any amendments or supplements thereto, the Schedule TO) and (y) the registration statement on Form S-4 with respect to the offer and sale of Parent Stock pursuant to the Offer and the Merger (together with any amendments or supplements thereto, the Registration Statement), in each case as originally filed with the SEC on November 21, 2005, and in each case so as to reflect the terms and conditions of this Agreement, and file such amendments or supplements with the SEC, and (ii) cause the Offer Documents (as defined below) to be disseminated to the holders of Shares, in each case, to the extent required by applicable law. The Schedule TO as so amended or supplemented shall contain an amended Offer to Exchange reflecting the terms and conditions of this Agreement, and a revised form of letter of transmittal and election (collectively with the Prospectus, and together with any amendments or supplements thereto, the Offer Documents),

Parent shall cause the Schedule TO and the Registration Statement to comply in all material respects with the provisions of applicable federal securities laws and, on the date filed with the SEC and on the date first published, sent or given to the Company’s stockholders, to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation is made by Parent with respect to information supplied by the Company in writing for inclusion in the Schedule TO or the Registration Statement. The Company shall promptly furnish to each of Parent and Merger Sub all information concerning the Company that is required or reasonably requested by either Parent or Merger Sub in connection with such actions. The Company, Parent and Merger Sub each agrees promptly to correct any information provided by it for use in the Schedule TO or Registration Statement if and to the extent that it shall have become false or misleading in any material respect, and Parent and Merger Sub further agree to take all steps necessary to cause the Schedule TO and Registration Statement as so corrected to be filed with the SEC and disseminated to the holders of the Shares, in each case as and to the extent required by applicable federal securities laws. Parent and Merger Sub further agree to promptly advise the Company of any comments or other communications (and promptly provide copies of any such written materials or reasonably detailed summaries of any oral communications) that Parent or Merger Sub or their counsel or representatives may receive from the SEC or its staff with respect to the Schedule TO or Registration Statement or any other securities filings of Parent or Merger Sub related to the Offer, the Merger or the transactions contemplated hereby or thereby.
      (j) Parent and Merger Sub shall comply with the obligations respecting prompt payment and announcement under the Exchange Act, and, without limiting the generality of the foregoing, Merger Sub shall, and Parent shall cause Merger Sub to, accept for payment, and pay for, all Shares validly tendered and not withdrawn pursuant to the Offer promptly following the acceptance of such Shares for payment pursuant to the Offer and this Agreement. Parent shall provide or cause to be provided to Merger Sub on a timely basis all funds and shares of Parent Stock necessary to purchase or exchange any Shares that Merger Sub becomes obligated to purchase or exchange pursuant to the Offer.

      (a) Promptly upon the purchase by Merger Sub of Shares pursuant to the Offer and from time to time thereafter, and subject to the last sentence of this Section 1.03(a), Parent shall be entitled to designate up to such number of directors, rounded to the nearest whole number, constituting at least a majority of the directors, on the Company Board as will give Parent representation on the Company Board equal to the product of the number of directors on the Company Board (giving effect to any increase in the number of

A-6

directors pursuant to this Section 1.03) and the percentage that the number of Shares beneficially owned by Parent and Merger Sub bears to the total number of outstanding Shares, and the Company shall use all reasonable efforts to, upon request by Parent, promptly, at the Company’s election, either increase the size of the Company Board or secure the resignation of such number of directors as is necessary to enable Parent’s designees to be elected or appointed to the Company Board and to cause Parent’s designees to be so elected or appointed. At such times, the Company will use its best efforts to cause persons designated by Parent to constitute a majority of each committee of the Company Board, other than any committee of the Company Board, if any, established to take action under this Agreement. Notwithstanding the foregoing, the Company shall use all reasonable efforts to ensure that three of the members of the Company Board as of the date hereof shall remain members of the Company Board until the Effective Time (as defined in Section 2.02 hereof). If the number of directors who are members of the Company Board as of the date hereof is reduced below three prior to the Effective Time, the remaining directors who are members of the Company Board as of the date hereof or their designees (or if there is only one such director, that remaining director) shall be entitled to designate a person (or persons) to fill such vacancy (or vacancies).
      (b) The Company’s obligation to appoint designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. Subject to the Parent’s compliance with the final sentence of this Section 1.03(b), the Company shall promptly take all actions, including filing an amendment to the Schedule 14D-9 (and disseminating such amendment to the stockholders of the Company to the extent required by applicable Laws) containing such information with respect to the Company and its officers and directors and Parent’s designees as Section 14(f) and Rule 14f-1 require, in order to fulfill its obligations under this Section. Parent shall timely supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and affiliates required by Section 14(f) and Rule 14f-1.
      (c) Following the election or appointment of Parent’s designees pursuant to this Section 1.03 and prior to the Effective Time, if there shall be any directors of the Company who were directors as of the date hereof, any amendment of this Agreement, any termination of this Agreement by the Company, any extension by the Company of the time for the performance of any of the obligations or other acts of Parent or Merger Sub or waiver of any of the Company’s rights hereunder or other action adversely affecting the rights of stockholders of the Company (other than Parent or Merger Sub), will require the concurrence of a majority of such directors.
      Section 1.04.     Top-Up Option.
      (a) Subject to the terms and conditions herein, the Company hereby grants to Merger Sub an irrevocable option (the Top-Up Option) to purchase up to that number of Shares (the Top-Up Option Shares) equal to the lowest number of Shares that, when added to the number of Shares collectively owned by Parent, Merger Sub and any of Parent’s other Subsidiaries immediately following consummation of the Offer shall constitute 90% of the Shares then outstanding (on a fully diluted basis, after giving effect to the issuance of the Top-Up Option Shares) at a purchase price per Top-Up Option Share equal to the Cash Consideration. Notwithstanding the foregoing provisions of this Section 1.04(a), the Top-Up Option shall not be exercisable if the aggregate number of Shares issuable upon exercise of the Top-Up Option, plus the aggregate number of then-outstanding Shares, plus the aggregate number of Shares issuable upon exercise of all options and other rights to purchase Shares, plus the aggregate number of shares reserved for issuance pursuant to the Company Stock Plans would exceed the number of authorized Shares.
      (b) The Top-Up Option may be exercised in whole, but not in part, at any one time after the occurrence of a Top-Up Exercise Event and prior to the occurrence of a Top-Up Termination Event.
        (i) A Top-Up Exercise Event shall occur upon Merger Sub’s acceptance for payment pursuant to the Offer of Shares constituting, together with Shares owned directly or indirectly by Parent or any other Subsidiaries of Parent, at least 80 percent, but less than 90 percent, of the Shares then outstanding.
 
        (ii) The Top-Up Termination Date shall occur upon the earliest to occur of (A) the Effective Time, (B) the termination of this Agreement, (C) the date that is ten business days after the occurrence

A-7


Table of Contents

  of a Top-Up Exercise Event, unless the Top-Up Option has been previously exercised in accordance with the terms and conditions hereof and (D) the date that is ten business days after the Top-Up Notice Date unless the Top-Up Closing shall have previously occurred.
      (c) To exercise the Top-Up Option, Merger Sub shall send to the Company a written notice (a Top-Up Exercise Notice, and the date of receipt of which notice is referred to herein as the Top-Up Notice Date) specifying the place for the closing of the purchase and sale of shares of Shares pursuant to the Top-Up Option (the Top-Up Closing) and a date not earlier than one business day nor later than ten business days after the Top-Up Notice Date for the Top-Up Closing. The Company shall, promptly after receipt of the Top-Up Exercise Notice, deliver a written notice to Merger Sub confirming the number of Top-Up Option Shares and the aggregate purchase price therefor.
      (d) At the Top-Up Closing, subject to the terms and conditions of this Agreement, (i) the Company shall deliver to Merger Sub a certificate or certificates evidencing the applicable number of Top-Up Option Shares, provided that the obligation of the Company to deliver Top-Up Option Shares upon the exercise of the Top-Up Option is subject to the condition that no provision of any applicable Law or judgment shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares in respect of any such exercise and (ii) Merger Sub shall purchase each Top-Up Option Share from the Company at a purchase price per Top-Up Option Share equal to the Cash Consideration. Payment by Merger Sub of the purchase price for the Top-Up Option Shares may be made, at Merger Sub’s option, by delivery of (A) immediately available funds by wire transfer to an account designated by the Company, (B) a demand note issued by Merger Sub in customary form that is reasonably acceptable to the parties, (C) shares of Parent Stock (valued based on the average closing price per share of Parent Stock over the five (5) consecutive trading days ending on and including the second full trading day preceding the Top-Up Closing), or (D) any combination thereof. Any demand note issued pursuant to the preceding sentence shall be accompanied by a credit support arrangement reasonably acceptable to the parties hereto.
      (e) Upon the delivery by Merger Sub to the Company of the Top-Up Exercise Notice, and the tender of the consideration described in Section 1.04(d), Merger Sub shall be deemed to be the holder of record of the Top-Up Option Shares issuable upon that exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing those Top-Up Option Shares shall not then be actually delivered to Merger Sub or the Company shall have failed or refused to designate the bank account described in Section 1.04(d).
      (f) Certificates evidencing Top-Up Option Shares delivered hereunder may include any legends legally required, including a legend in substantially the following form:
  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.
      (g) In the event Merger Sub exercises the Top-Up Option, the Company shall deliver to the Exchange Agent promptly after the Effective Time an amount of cash equal to the lesser of (i) the aggregate amount of cash paid by Merger Sub for the Top-Up Option Shares and (ii) the Maximum Cash Merger Consideration, and the Exchange Agent shall use such cash to pay the Cash Merger Consideration payable pursuant to Section 3.01 (the excess, if any, of (i) over (ii) shall be referred to as the Excess Cash Amount). For purposes of this Agreement, any cash paid to Company stockholders pursuant to the Merger as contemplated by the preceding sentence shall be deemed to be Cash Merger Consideration, and any cash payable to holders of Dissenting Shares pursuant to Section 3.02 shall first be paid from the Excess Cash Amount.
      Section 1.05.     Short Form Merger. If, after the consummation of the Offer and any exercise of the Top-Up Option, the number of Shares beneficially owned by Parent, Merger Sub and Parent’s other Subsidiaries collectively represent at least 90% of the then outstanding Shares, Parent shall cause Merger Sub to, and the Company shall execute and deliver such documents and instruments and take such other actions as

EXCHANGE OF CERTIFICATES
      Section 3.01.     Conversion of Securities.
      (a) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Sub or any holder of any Shares or any capital stock of Merger Sub:
        (i) Subject to this Article III, each Share issued and outstanding immediately prior to the Effective Time (other than Shares to be cancelled in accordance with Section 3.01(a)(ii) and Dissenting Shares referred to in Section 3.02) shall be converted into the right to receive, at the election of the holder, (A) $84.00 in cash, without interest but subject to proration as described below (the Cash Merger Consideration) or (B) 0.8498 shares of Parent Stock (the Stock Merger Considerationand, together with the Cash Merger Consideration, the Merger Consideration), subject to proration as described below, payable upon the surrender of the Certificates (as defined in Section 3.03(b)). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a Certificate representing any such Shares shall cease to have any rights with respect thereto, except the right to receive, upon surrender of such Certificate in accordance with Section 3.03, the Merger Consideration pursuant to this Section 3.01(a), any cash paid in respect of fractional shares payable pursuant to Section 3.03(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 3.03(c), without interest.
 
        (ii) All Shares that are (A) held by the Company as treasury shares or (B) owned by Parent or any wholly-owned Subsidiary of Parent, in each case, immediately prior to the Effective Time, shall be cancelled and retired and shall cease to exist, and no cash, securities of Parent or other consideration shall be delivered in exchange therefor.
 
        (iii) Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.
      (b) Subject to subparagraphs (c) through (g) below, each holder of Shares shall be entitled to elect (i) the number of Shares which such holder desires to exchange for the right to receive the Cash Merger Consideration (a Cash Merger Election), and (ii) the number of Shares which such holder desires to exchange for the right to receive Stock Merger Consideration (a Stock Merger Election). Any Cash Merger Election or Stock Merger Election shall be referred to herein as a Merger Election,” and shall be made on a form furnished by Parent for that purpose (a Form of Merger Election), which form may be part of the letter of election and transmittal delivered to former Company stockholders promptly following the Merger. Holders of record who hold Shares as nominees, trustees or in other representative capacities may submit multiple Forms of Merger Election on behalf of their respective beneficial holders. Any Shares as to which the holder has not submitted a properly completed Merger Election by the close of business on the Election Deadline shall be deemed to have made no Merger Election and be treated as specified in subparagraph (d)(iii) below.
      (c) The maximum aggregate amount of cash payable pursuant to the Merger shall be (x) $84.00 multiplied by (y) 45% of the total number of Shares canceled pursuant to the Merger (other than Shares canceled pursuant to Section 3.01(a)(ii)), minus the cash value of Dissenting Shares (such amount, the Maximum Cash Merger Consideration). For purposes of this Section 3.01, the “cash value of Dissenting Shares” assumes that the fair value, or “cash value”, of each Dissenting Share equals the Cash Merger Consideration. The maximum aggregate amount of Stock Merger Consideration issuable pursuant to the

A-10


Table of Contents

Merger shall be (x) 0.8498 shares of Parent Stock multiplied by (y) 55% of the total number of Shares canceled pursuant to the Merger (other than Shares canceled pursuant to Section 3.01(a)(ii)) (such amount, the Maximum Stock Merger Consideration).
        (i) If the total number of Cash Merger Elections would require aggregate cash in excess of the Maximum Cash Merger Consideration, such Cash Merger Elections shall be subject to proration as follows. For each Cash Merger Election, the number of Shares that shall be converted into the right to receive the Cash Merger Consideration shall be (A) the total number of Shares subject to such Cash Merger Election, multiplied by (B) the Merger Cash Proration Factor, rounded down to the nearest Share. The Merger Cash Proration Factor means a fraction (x) the numerator of which shall be the Maximum Cash Merger Consideration and (y) the denominator of which shall be the product of the aggregate number of Shares subject to all Cash Merger Elections made by all holders of Shares, multiplied by the Cash Merger Consideration. All Shares subject to a Cash Merger Election, other than Shares converted into the right to receive the Cash Merger Consideration in accordance with this Section 3.01(c), shall be converted into the right to receive the Stock Merger Consideration. All prorations resulting from this Section 3.01(c) shall be applied on a pro rata basis, such that each Company stockholder who surrenders Shares subject to a Cash Merger Election bears its proportionate share of the proration, based on the percentage of the total Shares surrendered subject to a Cash Merger Election that are surrendered by such Company stockholder, and shall be further subject to subparagraph (g) below, if applicable.
 
        (ii) If the total number of Stock Merger Elections would require aggregate Stock Merger Consideration in excess of the Maximum Stock Merger Consideration, such Stock Merger Elections shall be subject to proration as follows. For each Stock Merger Election, the number of Shares that shall be converted into the right to receive the Stock Merger Consideration shall be (A) the total number of Shares subject to such Stock Merger Election multiplied by (B) the Merger Stock Proration Factor, rounded down to the nearest Share. The Merger Stock Proration Factor means a fraction (x) the numerator of which shall be the Maximum Stock Merger Consideration and (y) the denominator of which shall be the product of the aggregate number of Shares subject to all Stock Merger Elections made by all holders of Shares multiplied by the Stock Merger Consideration. All Shares subject to a Stock Merger Election, other than that number converted into the right to receive the Stock Merger Consideration in accordance with this Section 3.01(c), shall be converted into the right to receive the Cash Merger Consideration. All prorations resulting from this Section 3.01(c) shall be applied on a pro rata basis, such that each Company stockholder who surrendered Shares subject to a Stock Merger Election bears its proportionate share of the proration, based on the percentage of the total Shares surrendered subject to a Stock Merger Election that are surrendered by such Company stockholder, and shall be further subject to subparagraph (g) below, if applicable.
      (d) Each Share canceled in exchange for the right to receive the Merger Consideration but which is not surrendered subject to a valid Merger Election, and any Dissenting Share as to which the holder does not validly perfect, or later waives, withdraws or loses the right to appraisal and payment under the DGCL prior to the Election Deadline, shall be deemed to be surrendered subject to the following Merger Elections:
        (i) If the Cash Merger Elections exceed the Maximum Cash Merger Consideration such that proration of Cash Merger Elections occur, Shares validly tendered without a valid Merger Election will be deemed tendered subject to a Stock Merger Election;
 
        (ii) If the Stock Merger Elections exceed the Maximum Stock Merger Consideration such that proration of Stock Merger Elections occurs, Shares validly tendered without a valid Election will be deemed tendered subject to a Cash Merger Election; and
 
        (iii) If no proration occurs, Shares validly tendered without a valid Merger Election, and any Dissenting Share as to which the holder does not validly perfect, or later waives, withdraws or loses the right to appraisal and payment under the DGCL prior to the Election Deadline, will be deemed tendered in part subject to a Cash Merger Election and in part subject to a Stock Merger Election to the extent of the Cash Merger Consideration and Stock Merger Consideration remaining after taking into account the

A-11


Table of Contents

  Cash Merger Elections and Stock Merger Elections made by those Company stockholders who affirmatively made Merger Elections in connection with the Merger. The remaining available Cash Merger Consideration and Stock Merger Consideration will be allocated on a pro rata basis among the Shares tendered by those Company stockholders who validly tendered Shares but did not tender subject to a valid Merger Election, and any Dissenting Share as to which the holder does not validly perfect, or later waives, withdraws or loses the right to appraisal and payment under the DGCL prior to the Election Deadline, such that each such Share is exchanged for the same proportion of Cash Merger Consideration and Stock Merger Consideration, based on the respective percentages of available Cash Merger Consideration and Stock Merger Consideration remaining after taking into account the affirmative Merger Elections of the tendering Company stockholders.
 
        (iv) Any Dissenting Shares as to which the holder fails to perfect or later waives, withdraws or loses the right to appraisal and payment under the DGCL after the Election Deadline shall be deemed tendered subject to a Cash Merger Election, and will remain subject to proration to the same extent as if such holder surrendered such formerly Dissenting Shares promptly following the Effective Time subject to a valid Cash Merger Election.
      (e) Change in Shares. If, between the date of this Agreement and the Effective Time, the outstanding shares of Parent Stock or the Shares shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Cash Consideration, Parent Stock Consideration, Maximum Cash Consideration, Maximum Parent Stock Consideration, Cash Proration Factor, Parent Stock Proration Factor, Cash Merger Consideration, the Stock Merger Consideration, the Maximum Cash Merger Consideration, the Maximum Stock Merger Consideration, the Merger Cash Proration Factor, the Merger Stock Proration Factor shall be correspondingly adjusted as appropriate to provide the holders of Shares and Company Stock Options the same economic effect as contemplated by this Agreement prior to such event.
      (f) Associated Rights. References in this Agreement to “Parent Stock” shall include, unless the context requires otherwise, the associated preferred share purchase rights (“Parent Rights) issued pursuant to the Rights Agreement, dated as of January 25, 2000, between Parent and Wells Fargo Bank, N.A. (as successor in interest to Equiserve Trust Company, N.A. and First Chicago Trust Company of New York )(as amended prior to the Effective Time, the Parent Rights Agreement). References in this Agreement to “Shares” shall include, unless the context requires otherwise, the associated preferred share purchase rights (“Company Rights) issued pursuant to the Amended and Restated Rights Agreement dated as of November 16, 1999 by and between the Company and U.S. Stock Transfer Corporation, as Rights Agent, as amended prior to the Effective Time (the Company Rights Agreement).
      (g) Notwithstanding anything in this Agreement to the contrary, if the product of (A) the number of shares of Parent Stock to be issued in the Offer and the Merger in exchange for Shares and (B) Testing Price (as defined below) of Parent Stock as reported on the NYSE on the last Business Day before the date of the public announcement of the Offer (or other applicable valuation date under Treasury Regulation Section 1.368-1(e)(2) for purposes of testing the continuity of interest requirement under Treasury Regulation Section 1.368-1(e)) (such date the Valuation Dateand such product the Value of Stock Consideration) is less than 40% of the sum of the Value of Stock Consideration and the amount of Non-Stock Consideration (as defined below), then the amount of cash consideration to be paid in the Merger in exchange for Shares shall be reduced and the number of shares of Parent Stock issued in the Merger in exchange for Shares shall be increased pro-rata based on the cash consideration to which the Company stockholder is otherwise entitled pursuant to the Merger under this Agreement so as to cause such percentage to be equal to 40%. The additional shares of Parent Stock to be issued in lieu of cash pursuant to the preceding sentence shall be determined using the Stock Merger Consideration. For purposes of this paragraph, the Non-Stock Considerationshall mean (a) any cash consideration paid pursuant to the Offer and the Merger, (b) any Company Distribution, and (c) any other cash or property (other than shares of Parent Stock) that is transferred, paid or distributed by Parent (or any Person related to Parent within the meaning of Treasury Regulation Section 1.368-1(e)(3)) to holders of Shares in exchange for Shares in connection with the Offer and Merger (including any cash paid on account of dissenting shares and any payments of expenses

      Section 3.02.     Dissenting Stockholders. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time that are held by a Person who shall not have voted to adopt this Agreement and who properly exercises and perfects appraisal rights for such Shares in accordance with Section 262 of the DGCL (the Dissenting Shares) will not be converted into a right to receive the applicable Merger Consideration as described in Section 3.01, but shall be converted into the right to receive such consideration as may be determined to be due pursuant to Section 262 of the DGCL; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal and payment under the DGCL after the Election Deadline, the right of such holder to such appraisal of its Dissenting Shares shall cease and such Shares shall be deemed canceled and converted as of the Effective Time into the right to receive the Merger Consideration as provided in Section 3.01 to which a holder who made a Cash Merger Election would be entitled, any cash paid in respect of fractional shares payable to any such holder pursuant to Section 3.03(e) and any dividends or other distributions to which any such holder is entitled pursuant to Section 3.03(c). The Company shall give Parent (a) prompt notice of any written demands for appraisal received by the Company, withdrawals of such demands, and any other related instruments served pursuant to Section 262 of the DGCL and received by the Company and (b) the opportunity to direct in compliance with all applicable Laws all negotiations and proceedings with respect to demands for appraisals under the DGCL; provided, that any definitive actions taken by the Company at the direction of Parent in respect of any such negotiations and proceedings may be conditioned upon occurrence of the Effective Time. The Company shall not, except with prior written consent of Parent, (i) voluntarily make any payment with respect to any demands for appraisal for Dissenting Shares, (ii) offer to settle, or settle, any such demands, (iii) waive any failure to timely deliver a written demand for appraisal in accordance with the DGCL or (iv) agree to do any of the foregoing.
      Section 3.03.     Exchange of Certificates.
      (a) As of the Effective Time, Parent shall deposit, or shall cause to be deposited, with Wells Fargo Bank, N.A. or another bank or trust company designated by Parent and reasonably satisfactory to the Company (the Exchange Agent), for the benefit of the holders of Shares, for exchange in accordance with this Article III through the Exchange Agent, (i) certificates representing a number of shares of Parent Stock equal to the Maximum Stock Merger Consideration issuable to the Company stockholders pursuant to Section 3.01 and (ii) an amount of cash sufficient to deliver to holders of Shares the Maximum Cash Merger Consideration to which they are entitled pursuant to Section 3.01. Parent further agrees to provide to the Exchange Agent, from time to time as needed, immediately available funds sufficient to pay any dividends and other distributions pursuant to Section 3.03(c). Any cash and certificates representing Parent Stock deposited with the Exchange Agent shall hereinafter be referred to as the Exchange Fund. Pursuant to irrevocable instructions, the Exchange Agent shall promptly deliver the Merger Consideration from the Exchange Fund to the former Company stockholders who are entitled thereto pursuant to Section 3.01. Except as contemplated by Sections 3.03(c) and 3.03(e) hereof, the Exchange Fund shall not be used for any other purpose.
      (b) Promptly (and in any event within five (5) Business Days) after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a certificate formerly representing Shares (a Certificate), other than Parent or Merger Sub or any wholly-owned Subsidiary of Parent or Merger Sub, (i) a letter of election and transmittal (which will include the Form of Merger Election) that shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, which letter shall be in customary form and (ii) instructions for effecting the surrender of such Certificates in exchange for the Merger Consideration.

therefor (A) one or more shares of Parent Stock representing, in the aggregate, the whole number of shares that such holder is entitled to receive pursuant to Section 3.01 (after taking into account any applicable proration or other adjustments and aggregating any fractional shares resulting from all Shares surrendered by such holder pursuant to the Merger), (B) the Cash Merger Consideration that such holder is entitled to receive pursuant to Section 3.01 in respect of the Shares represented by such Certificate and/or (C) a check in the amount of the cash that such holder is entitled to be paid in respect of any fractional shares of Parent Stock pursuant to Section 3.03(e) and dividends and other distributions pursuant to Section 3.03(c), if any, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or will accrue on any cash payable pursuant to Section 3.01, Section 3.03(c) or Section 3.03(e). In the event of a transfer of ownership of Shares which is not registered in the transfer records of the Company, the Merger Consideration may be issued and paid with respect to such Shares to such a transferee if the Certificate representing such transferred Shares is presented to the Exchange Agent in accordance with this Section 3.03(b), accompanied by all documents required to evidence and effect such transfer and evidence that any applicable stock transfer taxes have been paid.
      (c) No dividends or other distributions declared or made after the Effective Time with respect to the Parent Stock with a record date after the Effective Time shall be paid to any holder of any unsurrendered Certificate who is entitled to receive Parent Stock upon such surrender, and no cash payment in respect of fractional shares shall be paid to any such holder pursuant to Section 3.03(e), unless and until the holder of such Certificate shall surrender such Certificate in accordance with Section 3.03(b). Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the stock certificates representing whole shares of Parent Stock to be issued in exchange therefor, without interest, (i) promptly, (A) the amount of any cash payable pursuant to any Cash Merger Election and any cash payable with respect to a fractional share of Parent Stock to which such holder is entitled pursuant to Section 3.03(e) and (B) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to the date of surrender of such holder’s Certificate and a payment date occurring after the date of surrender, payable with respect to such whole shares of Parent Stock.
      (d) The Merger Consideration delivered upon surrender of Certificates in accordance with the terms hereof (including any cash paid pursuant to Section 3.03(c) or Section 3.03(e)) shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares represented by such Certificates.
      (e) In lieu of any fractional share of Parent Stock that otherwise would be issuable pursuant to the Merger, each holder of Shares who otherwise would be entitled to receive a fraction of a share of Parent Stock pursuant to the Merger will be paid an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the Exchange Agent for the Merger, on behalf of all such holders, of the aggregate fractional shares of Parent Stock issued pursuant to the Merger. As soon as practicable following the Election Deadline, the Exchange Agent shall determine the excess of (i) the number of whole shares of Parent Stock issuable to the holders of Shares pursuant to the Merger including fractional shares, over (ii) the aggregate number of whole shares of Parent Stock to be distributed to former holders of Shares pursuant to the Merger (such excess being collectively called the Excess Merger Parent Stock). The Exchange Agent, as agent and trustee for the former holders of Shares, shall as promptly as reasonably practicable sell the Excess Merger Parent Stock at the prevailing prices on the NYSE. The sales of the Excess Merger Parent Stock by the Exchange Agent shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. Parent shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent and costs associated with calculating and distributing the respective cash amounts payable to the applicable former holders of Shares, incurred in connection with such sales of Excess Merger Parent Stock. Until the proceeds of such sales have been distributed to the former holders of Shares to whom fractional shares of Parent Stock otherwise would have been issued in the Offer, the Exchange Agent will hold such proceeds in trust for such former holders. As soon as practicable after the

A-14


Table of Contents

determination of the amount of cash to be paid to former holders of Shares in lieu of any fractional shares of Parent Stock, the Exchange Agent shall distribute such amounts to such former holders.
      (f) Any portion of the Exchange Fund which remains undistributed to the holders of Shares six months after the Effective Time shall be returned to Parent, upon demand, and, from and after such delivery to Parent, any holders of Shares who have not theretofore complied with this Article III shall thereafter look only to Parent for the Merger Consideration payable in respect of such Shares, any cash paid in respect of fractional shares of Parent Stock to which they are entitled pursuant to Section 3.03(e) and any dividends or other distributions with respect to Parent Stock to which they are entitled pursuant to Section 3.03(c), in each case, without any interest thereon.
      (g) Neither Parent, Merger Sub, the Surviving Corporation, the Exchange Agent nor the Company shall be liable to any holder of Shares for any such shares of Parent Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.
      (h) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Surviving Corporation, the posting by such Person of a bond in such reasonable amount as Surviving Corporation may direct as indemnity against any claim that may be made against Surviving Corporation with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the Shares represented by such Certificate, any cash paid in respect of fractional shares of Parent Stock to which the holders thereof are entitled pursuant to Section 3.03(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 3.03(c), in each case, without any interest thereon.
      (i) Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer or this Agreement to any holder of Shares such amounts as Parent or the Exchange Agent are required to deduct and withhold under the Code, or any Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of whom such deduction and withholding was made by Parent or the Exchange Agent.
      (j) The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent upon termination of the Exchange Fund pursuant to Section 3.03(f). In the event the cash in the Exchange Fund shall be insufficient to fully satisfy all of the payment obligations to be made by the Exchange Agent hereunder, Parent shall promptly deposit cash into the Exchange Fund in an amount that is equal to the deficiency in the amount of cash required to fully satisfy such payment obligations.
      Section 3.04.     Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares theretofore outstanding on the records of the Company. From and after the Effective Time, the holders of Certificates representing Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or mandated by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent, the Surviving Corporation or Parent, for any reason, in accordance with Section 3.03(b), shall be canceled against delivery of the Merger Consideration payable in respect of the Shares formerly represented by such Certificates, any cash paid in respect of fractional shares of Parent Stock to which the holders thereof are entitled pursuant to Section 3.03(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 3.03(c), in each case, net of any required withholding for Tax and without any interest thereon.
      Section 3.05.     Stock Options.
      (a) Immediately prior to the Effective Time, each outstanding Company Stock Option shall become fully vested and exercisable. At the Effective Time and without any action on the part of the parties hereto or

A-15


Table of Contents

any holder of such Company Stock Options, each then outstanding Company Stock Option shall be canceled and converted into and shall thereafter represent only the right to receive:
        (i) a payment in cash equal to (i) 45% of the Cash Merger Consideration, minus 45% of the per Share cash exercise price for such respective Shares under such Company Stock Options, multiplied by (ii) the aggregate number of Shares issuable upon exercise of such Company Stock Options; and
 
        (ii) a number of shares of Parent Stock equal to (i) 0.46739 multiplied by (ii) the number determined pursuant to the following formula:
         
    X = Y × (A-B )
      A  
      Where X = the number to be multiplied by 0.46739
      Y = the total number of Shares subject to the Company Stock Option
      A = 0.46739 times the average closing sale prices for a share of Parent Stock over the five consecutive trading days ending on and including the second full trading day prior to the Effective Time plus $37.80
      B = the exercise price of the Shares subject to the Company Stock Option;
provided, however, that in lieu of any fractional shares of Parent Stock that otherwise would be issuable pursuant to this subparagraph (ii), the holder will receive an amount in cash (without interest) equal to such holder’s respective proportionate interest in the proceeds from the sale or sales in the open market by the Exchange Agent for the Offer, on behalf of all such holders, of the aggregate fractional shares of Parent Stock otherwise issuable pursuant to this subparagraph (ii).
      (b) The amount of cash and number of shares of Parent Stock to which the optionee otherwise would be entitled pursuant to subparagraphs (a) and (b) above shall be reduced by the total amount of withholding for applicable Taxes with respect to the aggregate Company Stock Options canceled and converted into the right to receive cash and Parent Stock pursuant to this Section 3.05. Such amounts for withholding shall first be deducted from the amounts otherwise payable pursuant to subparagraph (a) and, to the extent additional withholding is required, the number of shares of Parent Stock otherwise deliverable pursuant to subparagraph (b) will be reduced by the amount of remaining withholding, based on the value of a share of Parent Stock over the five consecutive trading days ending on and including the second full trading day prior to the Effective Time.
      (c) Parent shall cause Merger Sub to make all such payments as promptly as practicable, and in any event within fifteen (15) Business Days, after the Effective Time. As promptly as practicable after the date hereof, the Company shall (x) effect any amendments to the Company Stock Plans or any instruments granting or defining the rights of Company Stock Options, (y) obtain any necessary consents or approvals of the applicable holders of such Company Stock Options, and (z) take any other actions as may be permitted or required under the terms of the Company Stock Plans, any instruments granting or defining the rights of holders of such Company Stock Options, or applicable Law, necessary to effectuate this Section 3.05. Prior to the Effective Time, the Company shall provide notice to each holder of a Company Stock Option outstanding under the Company Stock Plans describing the accelerated vesting and cash out of such Company Stock Options in accordance with this Section 3.05.
      Section 3.06.     Employee Stock Purchase Plan. The Company shall take all requisite action with respect to the Company’s 2000 Employee Stock Purchase Plan, as amended (the Company ESPP), to ensure that (i) all outstanding Company Purchase Rights (as defined in Section 4.02) will be exercised no later than three (3) Business Days prior to the Expiration Date, (ii) no Company Purchase Rights will be issued and outstanding as of the Expiration Date, (iii) conditioned upon the occurrence of the Closing, the Company ESPP will be terminated no later than the Effective Time, and (iv) no additional offering periods shall commence on or after the Expiration Date. The Company shall deliver to Parent prior to the Expiration Date sufficient evidence that the Company ESPP will be terminated as of the Effective Time, conditioned upon the occurrence of the Closing. In addition, prior to the Effective Time, the Company shall take all

actions (including, if appropriate, amending the terms of the Company ESPP and the terms of any offering period(s) commencing prior to the Expiration Date) that are necessary to provide that, as of the Effective Time, participants and former participants in the Company ESPP shall cease to have any right or interest thereunder. Notwithstanding the foregoing, all actions taken and all amendments made pursuant to this Section 3.06 shall be taken or made in compliance with Sections 423 and 424 of the Code and so as not to result in a “modification” under such Sections. All Shares issued in connection with the exercise of the Company Purchase Rights shall be, at the Effective Time, converted into the right to receive the Merger Consideration in accordance with, and pursuant to, the terms and conditions of this Agreement.
      Section 3.07.     Restricted Stock. Pursuant to the terms of the Company’s Restricted Stock Plan, all outstanding rights that the Company may hold immediately prior to the Effective Time to acquire unvested Shares issued pursuant to the Company Restricted Stock Plan (the Repurchase Rights) shall lapse at the Effective Time.

      (b) The unpaid Taxes of the Company and its Subsidiaries did not, as of the date of the financial statements contained in the most recent Company SEC Filings, exceed the reserve for Tax liability (excluding any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the balance sheets (rather than in any notes thereto) contained in such financial statements. Since the date of the financial statements in the most recent Company SEC Filings filed prior to the date hereof, neither the Company nor any of its Subsidiaries has incurred any liability for Taxes outside the ordinary course of business or otherwise inconsistent with past custom and practice, except for any liability for Taxes which would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

      (d) No deficiencies for Taxes with respect to any of the Company and its Subsidiaries have been set forth or claimed in writing, or proposed or assessed by a Tax authority. There are no pending or, to the knowledge of the Company, proposed or threatened audits, investigations, disputes or claims or other actions for or relating to any Liability for Taxes with respect to any of the Company and its Subsidiaries, and there are no matters under discussion with any Tax authority, or known to the Company, with respect to Taxes that are likely to result in a material additional Liability for Taxes with respect to any of the Company and its Subsidiaries.

The Company has delivered or made available to Parent true and complete copies of federal, state and local income Tax Returns of each of the Company and its Subsidiaries and their predecessors for the years ended December 31, 2001, 2002, 2003 and 2004, and true and complete copies of all examination reports and statements of deficiencies assessed against or agreed to by any of the Company and its Subsidiaries or any predecessor, with respect to Taxes. None of the Company, any of its Subsidiaries or any predecessor has waived any statute of limitations in respect of Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency, or has made any request in writing for any such extension or waiver.
      (e) Each of the Company and its Subsidiaries has withheld and paid all material Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, stockholder or other third party, and all Tax Returns (including without limitation all IRS Forms W-2 and 1099) required with respect thereto have been properly completed and timely filed in all material respects. Neither the Company nor any of its Subsidiaries has classified any individual as an “independent contractor” or similar non-employee status who, according to any Company Benefit Plan or applicable Law, should have been classified as an employee, except to the extent that the failure to do so, individually or in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.
      (f) There are no Tax sharing agreements or similar arrangements (including indemnity arrangements) with respect to or involving any of the Company and its Subsidiaries, and, after the Closing Date, none of the

      (b) The Company also will consult with Parent regarding its business in a prompt manner and on a regular basis.
      (c) All nonpublic information provided to, or obtained by, a party in connection with the transactions contemplated hereby shall be “Proprietary Information” for purposes of the Confidentiality Agreement, the terms of which shall continue in force until the Effective Time; provided that Parent and the Company may disclose such information as may be necessary in connection with seeking the Parent Required Statutory Approvals, the Company Required Statutory Approvals and the Company Stockholder Approval.

      (a) From and after the Effective Time, Company Benefit Plans in effect as of the date of this Agreement shall remain in effect with respect to employees of the Company (or its Subsidiaries), covered by such plans at the Effective Time until such time as Parent shall, subject to applicable Law, the terms of this Agreement and the terms of such plans, either transfer employees and former employees of the Company and its Subsidiaries (Transferred Employees) to existing benefit plans of the Parent or Merger Sub or adopt new benefit plans with respect to such Transferred Employees (the Transferred Employee Plans). Prior to the Effective Time, Parent and the Company shall cooperate in reviewing, evaluating and analyzing Company Benefit Plans with a view towards determining appropriate Transferred Employee Plans. Parent will, and will cause its Subsidiaries to, with respect to all Transferred Employee Plans, (i) provide each employee of the Company or its Subsidiaries with service or other credit for all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to employees of the Company or its Subsidiaries under any Transferred Employee Plan that is a welfare plan that

Allergan, Inc.

Irvine, California 92612
     Re: Registration Statement on Form S-4
Ladies and Gentlemen:
      We have acted as counsel to Allergan, Inc. (“Allergan”), a Delaware corporation, in connection with the acquisition of Inamed Corporation (“Inamed”), a Delaware corporation, pursuant to the transactions described in a Registration Statement on Form S-4 filed with the United States Securities and Exchange Commission on November 21, 2005, as amended on December 9, 2005 (the“Registration Statement”). Unless otherwise indicated, capitalized terms not defined herein have the meanings set forth in the Registration Statement. Pursuant to the Registration Statement, (a) Banner Acquisition, Inc. (“Offeror”), a wholly owned subsidiary of Allergan is offering to exchange for each share of Inamed common stock validly tendered and not properly withdrawn in the Offer, at the election of the holder of such shares, either cash or shares of Allergan common stock, (b) promptly after completion of the Offer, Allergan will consummate a merger of Offeror with and into Inamed, with Inamed surviving the merger (the “Inamed Merger”) and, pursuant to the Inamed Merger, Allergan will issue in exchange for each share of Inamed common stock, at the election of the holder of shares of Inamed common stock, either cash or shares of Allergan common stock, and (c) promptly after the Inamed Merger, Allergan will cause Inamed to merge with and into a wholly owned limited liability company of Allergan, with the limited liability company surviving the Merger (the “Post-Closing Merger”).
      At your request, we have examined the Registration Statement to be filed on the date hereof with the Securities and Exchange Commission in connection with the registration of the shares of Allergan common stock to be issued to the stockholders of Inamed upon consummation of the proposed transaction.
      You have requested that we render the opinion set forth below. In rendering this opinion, we have reviewed (without any independent investigation) the Registration Statement and such other documents as we have deemed necessary or appropriate. We have relied upon the truth and accuracy at all relevant times of the facts and statements contained in the Registration Statement and representations as to factual matters contained in the representation letter received from Allergan, and have assumed that the proposed transaction will be consummated in accordance with the terms set forth therein and without any waiver of any material provision thereof. We have further assumed the accuracy of any representation or statement made “to the knowledge of” or similarly qualified without such qualification.

C-1


Table of Contents

      Based upon the foregoing, and subject to the assumptions, exceptions, limitations and qualifications set forth herein and set forth in the discussion in the Registration Statement under the caption “Material United States Federal Income Tax Consequences”, it is our opinion that:
        (a) the Offer, Inamed Merger, and the Post-Closing Merger will be treated as a single integrated transaction that qualifies as a reorganization under section 368(a) of the Internal Revenue Code (the “Code”).
 
        (b) the discussion in the Registration Statement, under the caption “Material U.S. States Federal Income Tax Consequences,” to the extent it constitutes descriptions of legal matters or legal conclusions, is accurate in all material respects.
      This opinion represents our best judgment regarding the application of federal income tax laws under the Internal Revenue Code of 1986, as amended, existing judicial decisions, administrative regulations and published rulings and procedures. Our opinion is not binding upon the Internal Revenue Service or the courts, and there is no assurance that the Internal Revenue Service will not successfully assert a contrary position. This opinion is being delivered prior to the consummation of the proposed transaction and therefore is prospective and dependent on future events. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, or future factual developments, would not adversely affect the accuracy of the conclusion stated herein. We undertake no responsibility to advise you of any new developments in the facts or in the application or interpretation of the federal income tax laws. Furthermore, in the event any one of the facts or statements or assumptions upon which we have relied to issue this opinion is incorrect, our opinion might be adversely affected and may not be relied upon.
      This opinion addresses only the matters described above, and does not address any other federal, state, local or foreign tax consequences that may result from the Offer, Inamed Merger, and the Post-Closing Merger, or any other transaction (including any transaction undertaken in connection with the foregoing). This opinion is rendered to you in connection with the filing of the Registration Statement and may be relied upon by persons entitled to rely on it pursuant to applicable provisions of federal securities law.
      We hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption “Material U.S. Federal Income Tax Consequences” in the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933 as amended, nor do we thereby admit that we are experts with respect to any part of such Registration Statement within the meaning of the term “experts” as used in the Securities Act of 1933, as amended.
  Very truly yours,

ANNEX D
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
      (a)     Notwithstanding any other provisions of this chapter, a corporation shall not engage in any business combination with any interested stockholder for a period of 3 years following the time that such stockholder became an interested stockholder, unless:
        (1)     prior to such time the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder, or
 
        (2)     upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer, or
 
        (3)     At or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 662/3% of the outstanding voting stock which is not owned by the interested stockholder.
      (b)     The restrictions contained in this section shall not apply if:
        (1)     the corporation’s original certificate of incorporation contains a provision expressly electing not to be governed by this section;
 
        (2)     the corporation, by action of its board of directors, adopts an amendment to its bylaws within 90 days of the effective date of this section, expressly electing not to be governed by this section, which amendment shall not be further amended by the board of directors.
 
        (3)     the corporation, by action of its stockholders, adopts an amendment to its certificate of incorporation or bylaws expressly electing not to be governed by this section, provided that, in addition to any other vote required by law, such amendment to the certificate of incorporation or bylaws must be approved by the affirmative vote of a majority of the shares entitled to vote. An amendment adopted pursuant to this paragraph shall be effective immediately in the case of a corporation that both (i) has never had a class of voting stock that falls within any of the three categories set out in subsection (b)(4) hereof, and (ii) has not elected by a provision in its original certificate of incorporation or any amendment thereto to be governed by this section. In all other cases, an amendment adopted pursuant to this paragraph shall not be effective until 12 months after the adoption of such amendment and shall not apply to any business combination between such corporation and any person who became an interested stockholder of such corporation on or prior to such adoption. A bylaw amendment adopted pursuant to this paragraph shall not be further amended by the board of directors;
 
        (4)     the corporation does not have a class of voting stock that is (i) listed on a national securities exchange, (ii) authorized for quotation on The NASDAQ Stock Market or (iii) held of record by more than 2,000 stockholders, unless any of the foregoing results from action taken, directly or indirectly, by an interested stockholder or from a transaction in which a person becomes an interested stockholder;
 
        (5)     a stockholder becomes an interested stockholder inadvertently and (i) as soon as practicable divests itself of ownership of sufficient shares so that the stockholder ceases to be an interested stockholder and (ii) would not, at any time within the 3 year period immediately prior to a business combination between the corporation and such stockholder, have been an interested stockholder but for the inadvertent acquisition of ownership;
 
        (6)     the business combination is proposed prior to the consummation or abandonment of and subsequent to the earlier of the public announcement or the notice required hereunder of a proposed transaction which (i) constitutes one of the transactions described in the second sentence of this

D-1


Table of Contents

  paragraph; (ii) is with or by a person who either was not an interested stockholder during the previous 3 years or who became an interested stockholder with the approval of the corporation’s board of directors or during the period described in paragraph (7) of this subsection (b); and (iii) is approved or not opposed by a majority of the members of the board of directors then in office (but not less than 1) who were directors prior to any person becoming an interested stockholder during the previous 3 years or were recommended for election or elected to succeed such directors by a majority of such directors. The proposed transactions referred to in the preceding sentence are limited to (x) a merger or consolidation of the corporation (except for a merger in respect of which, pursuant to section 251 (f) of the chapter, no vote of the stockholders of the corporation is required); (y) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), whether as part of a dissolution or otherwise, of assets of the corporation or of any direct or indirect majority-owned subsidiary of the corporation (other than to any direct or indirect wholly-owned subsidiary or to the corporation) having an aggregate market value equal to 50% or more of either that aggregate market value of all of the assets of the corporation determined on a consolidated basis or the aggregate market value of all the outstanding stock of the corporation; or (z) a proposed tender or exchange offer for 50% or more of the outstanding voting stock of the corporation. The corporation shall give not less then 20 days notice to all interested stockholders prior to the consummation of any of the transactions described in clauses (x) or (y) of the second sentence of this paragraph; or
 
        (7)     The business combination is with an interested stockholder who became an interested stockholder at a time when the restrictions contained in this section did not apply by reason of any paragraphs (1) through (4) of this subsection (b), provided, however, that this paragraph (7) shall not apply if, at the time such interested stockholder became an interested stockholder, the corporation’s certificate of incorporation contained a provision authorized by the last sentence of this subsection (b). Notwithstanding paragraphs (1), (2), (3) and (4) of this subsection, a corporation may elect by a provision of its original certificate of incorporation or any amendment thereto to be governed by this section; provided that any such amendment to the certificate of incorporation shall not apply to restrict a business combination between the corporation and an interested stockholder of the corporation if the interested stockholder became such prior to the effective date of the amendment.
      (c)     As used in this section only, the term:
        (1)     “affiliate” means a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, another person.

        (ii)     any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), except proportionately as a stockholder of such corporation, to or with the interested stockholder, whether as part of a dissolution or otherwise, of assets of the corporation or of any direct or indirect majority-owned subsidiary of the corporation which assets have an aggregate market value equal to 10% or more of either the aggregate market value of all the

D-2


Table of Contents

  assets of the corporation determined on a consolidated basis or the aggregate market value of all the outstanding stock of the corporation;
 
        (iii)     any transaction which results in the issuance or transfer by the corporation or by any direct or indirect majority-owned subsidiary of the corporation of any stock of the corporation or of such subsidiary to the interested stockholder, except (A) pursuant to the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into stock of such corporation or any such subsidiary which securities were outstanding prior to the time that the interested stockholder became such, (B) pursuant to a merger under Section 251(g) of this title; (C) pursuant to a dividend or distribution paid or made, or the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into stock of such corporation or any such subsidiary which security is distributed, pro rata to all holders of a class or series of stock of such corporation subsequent to the time the interested stockholder became such, (D) pursuant to an exchange offer by the corporation to purchase stock made on the same terms to all holders of said stock, or (E) any issuance or transfer of stock by the corporation, provided however, that in no case under (C)-(E) above shall there be an increase in the interested stockholder’s proportionate share of the stock of any class or series of the corporation or of the voting stock of the corporation;
 
        (iv)     any transaction involving the corporation or any direct or indirect majority-owned subsidiary of the corporation which has the effect, directly or indirectly, of increasing the proportionate share of the stock of any class or series, or securities convertible into the stock of any class or series, of the corporation or of any such subsidiary which is owned by the interested stockholder, except as a result of immaterial changes due to fractional share adjustments or as a result of any purchase or redemption of any shares of stock not caused, directly or indirectly, by the interested stockholder; or

Notwithstanding the foregoing, a presumption of control shall not apply where such person holds voting stock, in good faith and not for the purpose of circumventing this section, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group have control of such entity.
 
        (5)     “interested stockholder” means any person (other than the corporation and any direct or indirect majority-owned subsidiary of the corporation) that (i) is the owner of 15% or more of the outstanding voting stock of the corporation, or (ii) is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within the 3-year period immediately prior to the date on which it is sought to be determined whether such person is an interested stockholder; and the affiliates and associates of such person; provided, however, that the term “interested stockholder” shall not include (x) any person who (A) owned shares in excess of the 15% limitation set forth herein as of, or acquired such shares pursuant to a tender offer commenced prior to, December 23, 1987, or pursuant to an exchange offer announced prior to the aforesaid date and commenced within 90 days thereafter and either (I) continued to own shares in excess of such 15% limitation or would have but for action by the corporation or (II) is an affiliate or associate of the corporation and so continued (or so would have continued but for action by the corporation) to be the owner of 15% or more of the outstanding voting stock of the corporation at any time within the 3-year period immediately prior to the date on which it is sought to be determined whether such a person is an

  interested stockholder or (B) acquired said shares from a person described in (A) above by gift, inheritance or in a transaction in which no consideration was exchanged; or (y) any person whose ownership of shares in excess of the 15% limitation set forth herein in the result of action taken solely by the corporation provided that such person shall be an interested stockholder if thereafter such person acquires additional shares of voting stock of the corporation, except as a result of further corporate action not caused, directly or indirectly, by such person. For the purpose of determining whether a person is an interested stockholder, the voting stock of the corporation deemed to be outstanding shall include stock deemed to be owned by the person through application of paragraph (8) of this subsection but shall not include any other unissued stock of such corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise.

        (iii)     has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (B) of clause (ii) of this paragraph), or disposing of such stock with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such stock.
