FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain certain estimates, predictions, and other “forward-looking statements” (as defined in the Private Securities Litigation Reform Act of 1995, and within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Forward-looking statements are generally identified with the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “target,” “may,” “will,” “would,” “plan,” “project,” “should,” “continue” or the negative thereof or other similar expressions, or discussion of future goals or aspirations, which are predictions of or indicate future events and trends and which do not relate to historical matters.

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain statements that are forward looking within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, statements regarding: the Company’s intention to negotiate over fiscal 2011 and fiscal 2012 its withdrawal from the multi-employer defined benefit pension plans provided for in three remaining collective bargaining agreements that provide for such plans; the benefits to be derived from the SAP implementation; the Company’s expectation for future periods; the Company’s expectation for its overall effective tax rate for fiscal 2011; the Company’s belief that it can obtain financing on reasonable terms; the Company’s ability to manage its exposure to interest rate risk through the use of interest rate swap agreements; the performance of counterparties under interest rate swap agreements; the Company’s estimate that for every 25 basis point increase in LIBOR, annual interest expense will increase approximately $2.1 million; the estimate of future interest payments on the Company’s long-term debt obligations; and the estimate of future payments or receipts under interest rate swap agreements.

These forward-looking statements involve risks and uncertainties. Factors that could cause actual results to differ materially from those predicted in any forward-looking statement include, but are not limited to: the Company’s inability to meet its earnings estimates resulting from lower sales, decreased selling prices, higher product costs and/or higher operating expenses than that forecasted by the Company; weakening of the economy (compared to our expectations) resulting in weakening demand for the Company’s products; weakening operating and financial performance of the Company’s customers, which can negatively impact the Company’s sales and the Company’s ability to collect its accounts receivable; changes in the environmental regulations that affect the Company’s sales of specialty gases; higher or lower overall tax rates than that estimated by the Company resulting from changes in tax laws, changes in reserves and other estimates; increases in debt in future periods and the impact on the Company’s ability to pay and/or grow its dividend; a decline in demand from markets served by the Company; adverse customer response to the Company’s strategic product sales initiatives; a lack of cross-selling opportunities for the Company’s strategic products; a lack of specialty gas sales growth due to a downturn in certain markets; the negative effect of an economic downturn on strategic product sales and margins; the inability of strategic products to diversify against cyclicality; supply shortages of certain gases and the resulting inability of the Company to meet customer gas requirements; customers’ acceptance of current prices and of future price increases; adverse changes in customer buying patterns; a rise in product costs and/or operating expenses at a rate faster than the Company’s ability to increase prices; higher or lower capital expenditures than that estimated by the Company; limitations on the Company’s borrowing capacity dictated by the New Senior Credit Facility; fluctuations in interest rates; the Company’s ability to continue to access credit markets on satisfactory terms; the impact of tightened credit markets on the Company’s customers; the impact of changes in tax and fiscal policies and laws; the extent and duration of current economic trends in the U.S. economy; higher than expected implementation costs of the SAP system; conversion problems related to the SAP system that disrupt the Company’s business and negatively impact customer relationships; potential disruption to the Company’s business from integration problems associated with acquisitions; the Company’s success in continuing its cost reduction program; the Company’s ability to successfully identify, consummate and integrate acquisitions to achieve anticipated acquisition synergies; increased liabilities arising from withdrawals from the Company’s multi-employer pension plans; the inability to pay dividends as a result of loan covenant restrictions; the inability to manage interest rate exposure; higher interest expense than that estimated by the Company due to

RISK FACTORS

Any investment in the notes involves a high degree of risk. You should carefully consider the risks described below, as well as those discussed under “Risk Factors” in our Annual Report on Form 10-K for the year ended March 31, 2010 and our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2010, each incorporated by reference herein, before making a decision to invest in the notes. Some of these factors relate principally to our business. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also have a material adverse effect on our business and operations.

If any of the matters included in the following risks were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, you may lose all or part of your original investment.

Risks Relating to Investment in the Notes

The Air Products unsolicited takeover attempt and actions taken in connection therewith may be adverse to the interests of the holders of the notes.

As noted above, in February 2010, Air Products launched a tender offer to purchase all of our common stock for cash consideration of $60 per share. On July 8, 2010, Air Products revised its tender offer to $63.50 per share in cash and then on September 6, 2010, Air Products further revised its tender offer to $65.50 per share in cash. Air Products also initiated a proxy contest, which resulted in the election of three directors to our Board of Directors and a vote on the amendment of certain provisions of our By-Laws. The Company has initiated a suit in Delaware Chancery Court seeking an expedited judicial determination of the validity of one of the purported By-Law amendments. While our Board of Directors has announced its opposition to the tender offer, we cannot predict the ultimate outcome of the takeover attempt. Outcomes could include our being acquired by Air Products at the tender offer price or at a higher price (and/or for different consideration), our being acquired by, or merging with, another company or our remaining independent. Any such outcome or any steps we take in connection therewith, including incurring more debt, could adversely affect our financial condition and the value of the notes. During the three months ended June 30, 2010, we incurred $3.8 million of legal and professional fees related to Air Products’ unsolicited takeover attempt. We expect to incur additional costs in the future in connection with Air Products’ unsolicited takeover attempt. Except as set forth in “Description of the Notes—Covenants,” the notes will not include protections against incurrence of more debt or other steps that would have such an adverse impact. In addition, although we are required to offer to repurchase the notes at 101% of their aggregate principal amount upon a Change of Control Triggering Event (as defined in “Description of the Notes—Change of Control Triggering Event”), the tender offer, if successful, or any other potential transaction may not trigger such requirement. Specifically, the change of control provisions in the indenture may not protect you from certain important corporate events, such as a leveraged recapitalization, reorganization, restructuring, merger or other similar transaction, unless such a transaction constitutes a “Change of Control” under the indenture. Such a transaction may not involve a change in voting power or beneficial ownership or, even if it does, may not involve a change that constitutes a “Change of Control,” as defined in the indenture. For instance, for a change in directors to constitute a Change of Control, the majority of our Board of Directors would need to be replaced. All of our directors as of the date hereof, including those nominated by Air Products, are “continuing directors” as such term is defined in the indenture and used to determine whether a “Change of Control” has occurred under the terms of the indenture. Air Products may initiate another proxy contest to elect directors to our Board of Directors, which may trigger a Change of Control. However, under a recent Delaware Chancery Court interpretation of a change of control repurchase requirement with a continuing director provision, a board of directors may approve a slate of shareholder nominated directors without endorsing them or while simultaneously recommending and endorsing its own slate instead. The foregoing interpretation would permit our Board of Directors to approve a slate of directors that included a majority of dissident directors nominated pursuant to a proxy contest, and the ultimate election of such dissident slate would not constitute a “Change of

Control” that would trigger your right to require us to repurchase your notes as described above. In addition, even if the transaction constituted a Change of Control, our obligation to repurchase the notes would not be triggered unless the notes also cease to be rated investment grade by Moody’s and S&P within a period commencing 60 days prior to the first announcement of the Change of Control (or pending Change of Control) and ending 60 days following consummation of the Change of Control. Therefore, if an event occurs that does not constitute a “Change of Control,” as defined in the indenture, or the notes do not cease to be rated investment grade within the specified period, we will not be required to make an offer to repurchase the notes and you may be required to continue to hold your notes despite the event. See “Description of the Notes—Change of Control Triggering Event.”

Investors may find it difficult to trade the notes.

The notes are a new issue of securities, and there is currently no public market for the notes. We do not intend to apply for listing of the notes on any securities exchange. Although the underwriters have informed us that they intend to make a market in the notes, they are under no obligation to do so and may discontinue any market making activities at any time without notice. Any such market making will be subject to the limitations imposed by the Securities Act and the Exchange Act.

We also cannot assure you that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable. We also cannot assure you as to the level of liquidity of the trading market for the notes. Future trading prices of the notes will depend on many factors, including:

 

•

our operating performance, prospects and financial condition or the operating performance, prospects and financial condition of companies in our industry generally;

 

•

the interest of securities dealers in making a market for the notes; and

 

•

the market for similar securities.

It is possible that the market for the notes will be subject to disruptions. Any disruptions may have a negative effect on the holders of the notes, regardless of our prospects and financial performance.

Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and the market price of our securities.

Credit rating agencies rate our debt securities on factors that include our operating results, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading or downgrading the current rating or placing us on a watch list for possible future downgrading. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading would likely increase our cost of financing, including resulting in an increase to the interest rate applicable to borrowings under our New Senior Credit Facility, limit our access to the capital markets and have an adverse effect on the market price of our securities.

We may not have sufficient funds to purchase notes upon a change of control triggering event.

If there is a change of control triggering event under the terms of the indenture governing the notes, each holder of notes may require us to purchase all or a portion of their notes at a purchase price equal to 101% of the principal amount thereof, plus accrued interest to the date of purchase. In order to purchase any outstanding notes, we might have to refinance our outstanding indebtedness, which we might not be able to do. Even if we were able to refinance our other indebtedness, any financing might be on terms unfavorable to us. In addition, our New Senior Credit Facility provides that the occurrence of certain kinds of change of control events will constitute a default thereunder. We cannot assure you that we will have the financial ability to purchase outstanding notes upon the occurrence of a change of control. See “Description of the Notes—Change of Control Triggering Event.”

Table of Contents

The assets of our subsidiaries may not be available to make payments on the notes.

We are a holding company and our assets consist primarily of direct and indirect ownership interests in, and our business is conducted substantially through, our subsidiaries. We rely primarily on dividends or other distributions from our subsidiaries to meet our obligations for payment of principal and interest on our outstanding debt obligations and corporate expenses. Consequently, our ability to repay our debt, including the notes, depends on the earnings of our subsidiaries, as well as our ability to receive funds from our subsidiaries through dividends or other payments or distributions. The ability of our subsidiaries to pay dividends, repay intercompany debt or make other advances to us is subject to restrictions imposed by applicable laws (including bankruptcy laws), tax considerations and the terms of agreements governing our subsidiaries. Our foreign subsidiaries in particular may be subject to currency controls, repatriation restrictions, withholding obligations on payments to us and other limits. If we do not receive such funds from our subsidiaries, we may be unable to pay interest or principal on the notes when due.

In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, holders of their indebtedness and other liabilities, including their trade creditors and other obligations, including any preferred stock, will be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us. As a result, the notes are effectively subordinated to all of the liabilities of our subsidiaries which, as of June 30, 2010, were approximately $1.5 billion (of which $57 million consisted of debt for borrowed money and $295 million reflected indebtedness under our trade receivables securitization facility).

The instruments governing our indebtedness do not limit our acquisitions and may allow us to incur additional indebtedness in relation to acquisitions.

We have historically expanded our business through acquisitions. A part of our business strategy is to continue to grow through acquisitions that complement and expand our distribution network. During fiscal 2010, we completed six acquisitions. The indenture governing the notes, and the terms of our other indebtedness, do not limit the number or scale of acquisitions that we may complete. Because the consummation of acquisitions and integration of acquired businesses involves significant risk, this means that holders of the notes will be subject to the risks inherent in our acquisition strategy.

USE OF PROCEEDS

We anticipate that we will receive approximately $247.5 million in net proceeds from the offering of the notes, after deducting underwriting discounts and commissions and other estimated expenses of the offering.

We intend to use the net proceeds from the sale of the notes to repay borrowings under our New Senior Credit Facility, which we entered into on September 13, 2010. Our New Senior Credit Facility matures on September 13, 2014 and is comprised of a U.S. dollar revolving credit line and a multi-currency revolving credit line. The U.S. dollar revolving credit line and the multi-currency revolving credit line may bear interest at either a eurocurrency rate plus an applicable margin or, in the case of dollar-denominated borrowings, a U.S. base rate plus an applicable margin. At September 13, 2010, the applicable margin was equal to 2.125% per annum for eurocurrency rate borrowings and 1.125% per annum for U.S. base rate borrowings and the effective interest rate was equal to 2.397% per annum for U.S. base rate borrowings and 2.816% for eurocurrency rate borrowings. Borrowings under the New Senior Credit Facility were used to pay off our previous senior revolving credit facility. Each of the underwriters or their affiliates except Daiwa Capital Markets America Inc. are lenders under the New Senior Credit Facility and, as such, will receive their pro rata share of the amounts used from the net proceeds of this offering to repay indebtedness under the New Senior Credit Facility. See “Conflicts of Interest.”

(2)

On September 13, 2010, we entered into our New Senior Credit Facility, which has maximum availability of $650 million under a U.S. dollar revolving credit line and a $100 million (U.S. dollar equivalent) under a multi-currency revolving credit line. We also maintain a separate €3 million ($3.7 million U.S. dollar equivalent) French revolving credit line.

DESCRIPTION OF OTHER OBLIGATIONS

Senior Credit Facility

On September 13, 2010, we entered into a new four year $750 million revolving credit facility. The New Senior Credit Facility consists of a $650 million U.S. dollar revolving credit line, with a $65 million dollar letter of credit sublimit and a $50 million dollar swingline sublimit, and a $100 million (U.S. dollar equivalent) multi-currency revolving credit line. The maturity date of the revolving credit lines is September 13, 2014. Under certain circumstances, the revolving credit line may be increased by an additional $325 million, provided that the multi-currency revolving credit line may not be increased by more than an additional $50 million.

The U.S. dollar revolving credit line and the multi-currency revolving credit line may bear interest at either a eurocurrency rate (the “Eurocurrency Rate”) plus an applicable margin or, in the case of U.S. dollar-denominated borrowings, a U.S. base rate (the “U.S. Base Rate”) plus an applicable margin. The Eurocurrency Rate is equal to the British Bankers Association LIBOR Rate and is subject to adjustment for reserve requirements and mandatory costs. The U.S. Base Rate is equal to the highest of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America, N.A. as its “prime rate” and (c) the Eurocurrency Rate plus 1.0% per annum. The applicable margin is determined with reference to the credit rating of our non-credit enhanced, senior unsecured long-term debt. As of September 13, 2010, the effective interest rate was equal to 2.816% for Eurocurrency Rate borrowings and 2.397% per annum for U.S. Base Rate borrowings.

A commitment fee payable on the actual daily unused portion of the credit facility is determined with reference to the credit rating of our non-credit enhanced, senior unsecured long-term debt. As of September 13, 2010, the commitment fee was equal to 0.35% per annum. Swingline loans are not considered utilization of the credit facility for purposes of this calculation.

The New Senior Credit Facility contains customary affirmative and negative covenants, including a financial covenant whereby the ratio of funded indebtedness to consolidated EBITDA may be no greater than 3.5 to 1.0. The New Senior Credit Facility contains certain customary events of default, including, without limitation, failure to make payments, breaches of covenants, breaches of representations and warranties, certain monetary judgments and bankruptcy and ERISA events. The New Senior Credit Facility also contains cross-default provisions whereby a default under the senior and senior subordinated notes discussed below or the notes offered hereby would likely result in a default under the New Senior Credit Facility. In the event of default, repayment of borrowings under the New Senior Credit Facility may be accelerated.

As of September 13, 2010, the Company has borrowings under the New Senior Credit Facility of $365 million, €10.2 million, £11.8 million and C$10 million and would be able to borrow up to approximately $344.4 million under our New Senior Credit Facility.

The Company also maintains a committed revolving line of credit of up to €3 million (U.S. $3.7 million) to fund its expansion into France. These revolving credit borrowings are outside of the New Senior Credit Facility. At June 30, 2010, French revolving credit borrowings were €1.7 million (U.S. $2.1 million). The variable interest rates on the French revolving credit borrowings are based on the eurocurrency rate plus an applicable rate determined with reference to the credit rating of our non-credit enhanced, senior unsecured long-term debt. As of September 13, 2010, the effective interest rate on the French revolving credit borrowings was equal to 2.698% per annum.

Money Market Loans

The Company has an agreement with a financial institution that provides access to short-term advances not to exceed $35 million. The agreement expires on December 1, 2010, but may be extended subject to renewal provisions contained in the agreement. The advances are generally overnight or for up to seven days. The

amount, term and interest rate of an advance are established through mutual agreement with the financial institution when the Company requests such an advance. At June 30, 2010, there were no advances outstanding under the agreement.

Senior Notes

At June 30, 2010, the Company had $400 million of 4.5% senior notes (the “2009 Notes”) outstanding. The 2009 Notes were issued at a discount and mature on September 15, 2014 with an effective yield of 4.527%. Interest on the 2009 Notes is payable semi-annually on March 15 and September 15 of each year. Additionally, the Company has the option to redeem the 2009 Notes prior to their maturity, in whole or in part, at 100% of the principal plus any accrued but unpaid interest and applicable make-whole payments.

At June 30, 2010, the Company had $300 million of 2.85% senior notes (the “2010 Notes”) outstanding. The 2010 Notes were issued at a discount and mature on October 1, 2013 with an effective yield of 2.871%. Interest on the 2010 Notes is payable semi-annually on April 1 and October 1 of each year, commencing on October 1, 2010. Additionally, the Company has the option to redeem the 2010 Notes prior to their maturity, in whole or in part, at 100% of the principal plus any accrued but unpaid interest and applicable make-whole payments.

Senior Subordinated Notes

At June 30, 2010, the Company had $220 million of its 2008 Notes outstanding with a maturity date of October 1, 2018. The 2008 Notes bear interest at a fixed annual rate of 7.125%, payable semi-annually on October 1 and April 1 of each year. The 2008 Notes have a redemption provision, which permits the Company, at its option, to call the 2008 Notes at scheduled dates and prices. The first scheduled optional redemption date is October 1, 2013 at a price of 103.563% of the principal amount. Subsequent to June 30, 2010, the Company repurchased $5 million of the 2008 Notes at a weighted average price of 110.5%. A loss on the early extinguishment of debt of approximately $0.6 million will be recognized related to the redemption premium and the write-off of unamortized debt issuance costs during the second quarter ending September 30, 2010.

The 2008, 2009 and 2010 Notes contain covenants that could restrict the payment of dividends, the repurchase of common stock, the issuance of preferred stock, and the incurrence of additional indebtedness and liens.

Acquisition and Other Notes

Our long-term debt also includes acquisition and other notes, principally consisting of notes issued to sellers of businesses acquired, which are repayable in periodic installments. At June 30, 2010, acquisition and other notes totaled $14.4 million with an average interest rate of approximately 6% and an average maturity of approximately two years.

Trade Receivables Securitization

We participate in a Securitization Agreement with three commercial banks to which we sell qualifying trade receivables on a revolving basis. Effective April 1, 2010, the Company’s sale of qualified trade receivables is now accounted for under new accounting guidance as a secured borrowing under which qualified trade receivables collateralize amounts borrowed from the commercial banks. Trade receivables that collateralize the Securitization Agreement are held in a bankruptcy-remote special purpose entity, which is consolidated for financial reporting purposes. Qualified trade receivables in the amount of the outstanding borrowing under the Securitization Agreement are not available to the general creditors of the Company. The maximum amount of the Securitization Agreement is $295 million and it bears interest at LIBOR plus 95 basis points. At June 30, 2010, the amount of outstanding borrowing under the Securitization Agreement has been classified as long-term debt

on the Consolidated Balance Sheet. Amounts borrowed under the Securitization Agreement fluctuate monthly based on the Company’s funding requirements and the level of qualified trade receivables available to collateralize the Securitization Agreement. The Securitization Agreement expires in March 2012 and contains customary events of termination, including standard cross default provisions with respect to outstanding debt. The amount of outstanding borrowing under the Securitization Agreement at June 30, 2010 was $295 million.

Interest Rate Swap Agreements

We manage our exposure to changes in market interest rates. Our involvement with derivative instruments is limited to highly effective fixed interest rate swap agreements used to manage well-defined interest rate risk exposures. At June 30, 2010, the Company had seven fixed interest rate swap agreements outstanding with an aggregate notional amount of $250 million. These swaps effectively converted $250 million of variable interest rate debt associated with the previous senior revolving credit facility to fixed rate debt. At June 30, 2010, these swap agreements required the Company to make fixed interest payments based on a weighted average effective rate of 3.21% and receive variable interest payments from the counterparties based on a weighted average variable rate of 0.96%. At June 30, 2010, the remaining terms of these swap agreements ranged from three to six months.

At June 30, 2010, we had five variable interest rate swaps outstanding with a notional amount of $300 million. These variable interest rates swaps effectively convert the Company’s $300 million of fixed rate 2010 Notes to variable rate debt. At June 30, 2010, these swap agreements required the Company to make variable interest payments based on a weighted average forward rate of 2.30% and receive fixed interest payments from the counterparties based on a fixed rate of 2.85%. The maturity of these fair value swaps coincides with the maturity date of the 2010 Notes in October 2013.

DESCRIPTION OF THE NOTES

Airgas will issue the notes under an Indenture, dated as of May 27, 2010, between itself and U.S. Bank National Association, as trustee, as supplemented by a supplemental indenture to be dated as of September , 2010 with respect to the notes, between Airgas and U.S. Bank National Association, as trustee (the “Supplemental Indenture”). As used in this section, all references to the “Indenture” mean the Indenture as supplemented by the Supplemental Indenture. The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939.

The following description is a summary of the material provisions of the Indenture and should be read in connection with the summary set forth under “Description of the Debt Securities” in the accompanying prospectus. It does not restate that agreement in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the notes. Copies of the Indenture are available by writing to Airgas, Inc., 259 North Radnor-Chester Road, Suite 100, Radnor, Pennsylvania 19087-5283, Attn: General Counsel. In this description, “Airgas,” “we,” “us” and “our” refers only to Airgas, Inc. and not to any of our subsidiaries. You can find the definitions of certain terms used in this description under the subheading “Covenants—Definitions.” Certain defined terms used in this description but not defined below under “Covenants—Definitions” have the meanings assigned to them in the Indenture.

Maturity, Principal and Interest

The notes will mature on October 1, 2015, and will be issued in an initial aggregate principal amount of $250 million. Additional notes of the same class and series may be issued in one or more tranches from time to time, without notice to or the consent of the existing holders of the notes, provided that if such additional notes are not fungible with the original notes for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number. Notes will be issued in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

The notes will be our unsecured unsubordinated obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness from time to time outstanding. The notes will be senior to any of our subordinated indebtedness from time to time outstanding and will rank junior to our secured indebtedness from time to time outstanding to the extent of the value of the assets securing such indebtedness. The notes will also be effectively junior in right of payment to all existing and future liabilities, including trade payables, of our subsidiaries.

Each note will bear interest at the rate described on the cover page from September 30, 2010 or from the most recent interest payment date on which interest has been paid, payable semiannually in arrears on April 1 and October 1 of each year, commencing April 1, 2011. We will pay interest to the person in whose name the note (or any predecessor note) is registered at the close of business on the March 15 or September 15 immediately preceding the relevant interest payment date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Optional Redemption

The notes will be redeemable, as a whole or in part, at our option, at any time or from time to time. If the notes are redeemed prior to the date that is one month prior to the maturity date of the notes, the notes may be redeemed by us at a redemption price equal to the greater of:

(1) 100% of the principal amount of the notes to be redeemed, and

(2) as determined by the Reference Treasury Dealer, the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate, plus 30 basis points.

Table of Contents

If the notes are redeemed on or after the date that is one month prior to the maturity date of the notes, the notes may be redeemed by us at a redemption price equal to 100% of the principal amount of the notes to be redeemed.

In each case, accrued interest will be payable to the redemption date and the principal amount of any note remaining outstanding after redemption in part shall be $2,000 and any integral multiple of $1,000 in excess thereof.

Holders of notes to be redeemed will receive notice thereof by first class mail at least 30 days and not more than 60 days before the date fixed for redemption. If fewer than all of the notes are to be redeemed, the trustee will select, at least 30 days and not more than 60 days prior to the redemption date, the particular notes or portions thereof for redemption from the outstanding notes not previously called by such method as the trustee deems fair and appropriate.

On and after the redemption date, interest will cease to accrue on the notes or any portion of the notes called for redemption unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent (or the trustee) money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on that date.

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means any of Banc of America Securities LLC, Goldman, Sachs & Co. or Wells Fargo Securities, LLC, as appointed by us, and their respective successors, or if all of such firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by us.

“Reference Treasury Dealer” means (1) each of Banc of America Securities LLC, Goldman, Sachs & Co. and a Primary Treasury Dealer (defined herein) selected by Wells Fargo Securities, LLC and their respective successors, provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute for such bank another Primary Treasury Dealer and (2) any other Primary Treasury Dealer selected by the Independent Investment Banker after consultation with us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity

corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated on the third business day preceding the redemption date.

Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event, unless we have exercised our right to redeem the notes as described under “—Optional Redemption,” each holder of notes will have the right to require us to purchase all or a portion (equal to $2,000 and any integral multiple of $1,000 in excess thereof) of such holder’s notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Change of Control Triggering Event occurs or, at our option, prior to any Change of Control but after the public announcement of the pending Change of Control, we will be required to send, by first class mail, a notice to each holder of notes, with a copy to the trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, we will, to the extent lawful, (1) accept or cause a third party to accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer; (2) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and (3) deliver or cause to be delivered to the trustee the notes accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being repurchased.

We will not be required to make a Change of Control Offer with respect to the notes if a third party involved in the applicable Change of Control makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and such third party purchases all the notes properly tendered and not withdrawn under its offer.

We will comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

For purposes of the foregoing discussion of a Change of Control Offer, the following definitions are applicable:

“Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used

 

S-19

Table of Contents

in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition. The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning.

“Change of Control” means the occurrence of any of the following:

(1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of Airgas and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than a Principal or a Related Party of a Principal;

(2) the adoption of a plan relating to the liquidation or dissolution of Airgas;

(3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above) other than a Principal and its Related Parties, becomes the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of Airgas, measured by voting power rather than number of shares;

(4) Airgas consolidates with, or merges with or into, any Person (other than a Principal or a Related Party of a Principal), or any Person (other than a Principal or a Related Party of a Principal) consolidates with, or merges with or into, Airgas, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of Airgas or such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Voting Stock of Airgas outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving Person immediately after giving effect to such transaction; or

(5) the first day on which a majority of the members of the board of directors of Airgas are not Continuing Directors.

“Change of Control Triggering Event” means, with respect to the notes, the notes cease to be rated Investment Grade by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by us of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change). Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Continuing Directors” means, as of any date of determination, any member of the board of directors of Airgas who:

(1) was a member of such board of directors on the date of this prospectus supplement;

(2) was nominated for election or elected to such board of directors with the approval of a majority of the Continuing Directors who were members of such board of directors at the time of such nomination or election; or

(3) is a designee of a Principal or was nominated by a Principal.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by us under the circumstances permitting us to select a replacement agency and in the manner for selecting a replacement agency, in each case as set forth in the definition of “Rating Agency.”

Table of Contents

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Person” means any individual, corporation, partnership, joint venture, association, joint-stock company, trust, unincorporated organization, limited liability company, government or any agency or political subdivision thereof or any other entity.

“Principal” means Peter McCausland (and in the event of his incompetence or death, his estate, heirs, executor, administrator, committee or other personal representative (collectively, “heirs”)) or any Person controlled, directly or indirectly, by Peter McCausland or his heirs.

“Rating Agency” means each of Moody’s and S&P; provided, that if Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside our control, we may appoint another “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act as a replacement for such Rating Agency; provided, that we shall give notice of such appointment to the trustee.

“Related Party” means:

(1) any immediate family member (in the case of an individual) of the Principal; or

(2) any trust, corporation, partnership or other entity, the beneficiaries, stockholders, partners, owners or Persons beneficially holding an 80% or more controlling interest of which consist of the Principal.

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and its successors.

“Voting Stock” of any specified Person as of any date means the Capital Stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of Airgas, Inc. and its Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that we offer to repurchase the notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of Airgas, Inc. and its Subsidiaries taken as a whole to another Person or group may be uncertain.

In addition, under a recent Delaware Chancery Court interpretation of a change of control repurchase requirement with a continuing director provision, a board of directors may approve a slate of shareholder nominated directors without endorsing them or while simultaneously recommending and endorsing its own slate instead. The foregoing interpretation would permit our Board of Directors to approve a slate of directors that included a majority of dissident directors nominated pursuant to a proxy contest, and the ultimate election of such dissident slate would not constitute a “Change of Control Triggering Event” that would trigger your right to require us to repurchase your notes as described above.

Covenants

Restrictions on Liens

We will not, and will not permit any Restricted Subsidiary to, Incur any Indebtedness secured by any Lien on any shares of stock, Indebtedness or other obligations of a Restricted Subsidiary or any Principal Property of ours or a Restricted Subsidiary, whether such shares of stock, Indebtedness or other obligations of a Subsidiary or Principal Property is owned at the date of the Indenture or thereafter acquired, without in any such case effectively providing that all the notes will be directly secured equally and ratably with such Lien.

Table of Contents

These restrictions do not apply to:

(1) the Incurrence of any Lien on any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property acquired after the date of the Indenture (including acquisitions by way of merger or consolidation) by us or a Restricted Subsidiary contemporaneously with such acquisition, or within 180 days thereafter, to secure or provide for the payment or financing of any part of the purchase price thereof, or the assumption of any Lien upon any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property acquired after the date of the Indenture existing at the time of such acquisition, or the acquisition of any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property subject to any Lien without the assumption thereof, provided that every such Lien referred to in this clause (1) shall attach only to the shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property so acquired and fixed improvements thereon;

(2) any Lien on any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property existing on the date the notes are initially issued;

(11) any renewal of or substitution for any Lien permitted by any of the preceding clauses (1) through (4), provided, in the case of a Lien permitted under clause (1), (2) or (4), the debt secured is not increased nor the Lien extended to any additional assets.

Notwithstanding the foregoing, we or any Restricted Subsidiary may create or assume Liens in addition to those permitted by clauses (1) through (11), and renew, extend or replace such Liens, provided that at the time of such creation, assumption, renewal, extension or replacement of such Lien, and after giving effect thereto, the total outstanding Indebtedness secured by Liens Incurred pursuant to this paragraph, together with the total outstanding Attributable Debt Incurred in connection with any sale and leaseback transactions entered into pursuant to the provisions of the Indenture described below in the last paragraph under “—Covenants— Limitation on Sale and Leaseback Transactions,” does not exceed 10% of Consolidated Net Tangible Assets.

For the purposes of this “Restrictions on Liens” covenant and the “Limitation on Sale and Leaseback Transactions” covenant, the giving of a guarantee which is secured by a Lien on any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property, and the creation of a Lien on any shares of stock, Indebtedness or other obligations of a Subsidiary or any Principal Property to secure Indebtedness that existed prior to the creation of such Lien, shall be deemed to involve the creation of Indebtedness in an amount equal to the principal amount guaranteed or secured by such Lien.

Table of Contents

Given the size of our operations, at any given time we expect to have very few or no Principal Properties and, accordingly, very few or no Restricted Subsidiaries.

Limitation on Sale and Leaseback Transactions

We will not, and will not permit any Restricted Subsidiary to, sell or transfer, directly or indirectly, except to us or a Restricted Subsidiary, any Principal Property as an entirety, or any substantial portion thereof, with the intention of taking back a lease of such property, except a lease for a period of three years or less at the end of which it is intended that the use of such property by the lessee will be discontinued; provided that, notwithstanding the foregoing, we or any Restricted Subsidiary may sell any such Principal Property and lease it back for a longer period:

(1) if we or such Restricted Subsidiary would be entitled, pursuant to the provisions of the Indenture described above under “—Restrictions on Liens,” to create a mortgage on the property to be leased securing Funded Debt in an amount equal to the Attributable Debt with respect to such sale and leaseback transaction without equally and ratably securing the outstanding notes;

(2) if we promptly inform the trustee of such transaction, the net proceeds of such transaction are at least equal to the fair market value (as determined by board resolution) of such property, and we cause an amount equal to the net proceeds of the sale to be applied to the retirement, within 180 days after receipt of such proceeds, of Funded Debt Incurred or assumed by us or a Restricted Subsidiary (including the notes); or

(3) if we, within 180 days after the sale or transfer, apply or cause a Restricted Subsidiary to apply an amount equal to the greater of the net proceeds of such sale or transfer or the fair market value of the Principal Property (or portion thereof) so sold and leased back at the time of entering into such sale and leaseback transaction (in either case as determined by board resolution) to purchase other Principal Property having a fair market value at least equal to the fair market value of the Principal Property (or portion thereof) sold or transferred in such sale and leaseback transaction.

Notwithstanding the foregoing, we or any Restricted Subsidiary may enter into sale and leaseback transactions in addition to those permitted in the foregoing paragraph and without any obligation to retire any outstanding notes or other Funded Debt, provided that at the time of entering into such sale and leaseback transactions and after giving effect thereto, the total outstanding Attributable Debt Incurred pursuant to this paragraph, together with any of the total outstanding Indebtedness secured by Liens created, assumed or otherwise incurred pursuant to the provisions of the Indenture described above in the third paragraph under “—Covenants—Restrictions on Liens,” does not exceed 10% of Consolidated Net Tangible Assets.

“Attributable Debt” means, when used in connection with a sale and leaseback transaction, at any date of determination, the product of (1) the net proceeds from such sale and leaseback transaction multiplied by (2) a fraction, the numerator of which is the number of full years of the term of the lease relating to the property involved in such sale and leaseback transaction (without regard to any options to renew or extend such term) remaining at the date of the making of such computation and the denominator of which is the number of full years of the term of such lease measured from the first day of such term.

“Capital Stock” means, with respect to any Person, any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests (including partnership interests) in (however designated) the equity of such Person, including any preferred stock, but excluding any debt securities convertible into such equity.

“Lien” with respect to any property or assets, means any mortgage or deed of trust, pledge, hypothecation, assignment, deposit arrangement, security interest, lien, charge, easement (other than any easement not materially impairing usefulness or marketability), encumbrance, preference, priority or other security agreement or preferential arrangement of any kind or nature whatsoever on or with respect to such property or assets (including, without limitation, any conditional sale or other title retention agreement having substantially the same economic effect as any of the foregoing), but not including the interest of a lessor under a lease that is an operating lease under generally accepted accounting principles.

“Principal Property” means any land, land improvements or building, together with the land upon which it is erected and fixtures comprising a part thereof, in each case, owned or leased by us or any Restricted Subsidiary and located in the United States, the gross book value (without deduction of any reserve for depreciation) of which on the date as of which the determination is being made is an amount which exceeds 1.0% of Consolidated Net Tangible Assets.

Consolidation; Merger or Sale of Substantially All Assets

We may: (1) consolidate or merge with or into another Person; or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of our properties or assets and our Subsidiaries taken as a whole, in one or more related transactions, to another Person; if:

(1) either: (a) we are the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than Airgas) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia (any such Person, the “Successor Company”);

(2) the Successor Company assumes all the obligations of Airgas under the notes and the Indenture pursuant to agreements reasonably satisfactory to the trustee; and

(3) immediately after such transaction no default exists.

The Successor Company will be the successor to Airgas and shall succeed to, and be substituted for, and may exercise every right and power of, Airgas under the Indenture, and the predecessor company shall be released from its obligations with respect to the notes, including with respect to its obligation to pay the principal of and interest on the notes. Under these circumstances, if our properties or assets become subject to a Lien not permitted by the Indenture, we will equally and ratably secure the notes.

Reports

Whether or not required by the Commission, so long as any notes are outstanding, Airgas will furnish to the holders of notes, within the time periods specified in the Commission’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if Airgas were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by Airgas’ certified independent accountants; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if Airgas were required to file such reports.

In addition, whether or not required by the Commission, Airgas will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request.

Events of Default

An event of default under the Indenture with respect to the notes includes the following:

 

•

failure to pay interest on the notes for 30 days;

 

•

failure to pay principal on the notes when due;

 

•

failure to perform any of the other covenants or agreements in the Indenture relating to the notes that continues for 60 days after written notice to us by the trustee or holders of at least 25% in principal amount of the notes then outstanding (for purposes of the financial statement reporting covenant, the 60 day grace period will be extended to 90 days);

 

•

default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by Airgas or any of its Significant Subsidiaries (or the payment of which is guaranteed by Airgas or any of its Significant Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the date of the

Table of Contents

Indenture, if that default (a) is caused by a failure to pay principal at its stated maturity after giving effect to any applicable grace period provided in such Indebtedness (a “Payment Default”); or (b) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $100.0 million or more; or

 

•

certain events of bankruptcy, insolvency or reorganization relating to us.

The Indenture provides that the trustee will, with certain exceptions, notify the holders of notes of any event of default known to it with respect to the notes within 90 days after the occurrence of such event.

If an event of default (other than with respect to certain events of bankruptcy, insolvency or reorganization) occurs and is continuing with respect to the notes, the trustee or the holders of not less than 25% in principal amount of the notes then outstanding may declare the principal amount to be due and payable. If an event of default with respect to certain events of bankruptcy, insolvency or reorganization occurs and is continuing, then all of the notes will ipso facto become and be due and payable immediately in an amount equal to the principal amount of the notes, together with accrued and unpaid interest, if any, to the date the notes become due and payable, without any declaration or other act on the part of the trustee or any holder. Subject to certain conditions, the holders of a majority in principal amount of the notes then outstanding can rescind and annul such declaration and its consequences.

We are required to file an annual officers’ certificate with the trustee concerning our compliance with the Indenture. Subject to the provisions of the Indenture relating to the duties of the trustee, the trustee is not obligated to exercise any of its rights or powers at the request or direction of any of the holders unless they have offered the trustee security or indemnity satisfactory to the trustee. If the holders provide security or indemnity satisfactory to the trustee, the holders of a majority in principal amount of the outstanding notes during an event of default may direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the Indenture or exercising any of the trustee’s trusts or powers with respect to the notes.

Prior to the acceleration of the maturity of the notes, the holders of not less than a majority in aggregate principal amount of the outstanding notes may on behalf of the holders of all outstanding notes waive any past default or event of default and its consequences, except a default or event of default (a) in the payment of the principal of, premium, if any, or interest on any note (which may only be waived with the consent of each holder of notes affected) or (b) in respect of a covenant or a provision of the Indenture which cannot be modified or amended without the consent of the holder of each note outstanding affected by such modification or amendment.

Book-Entry, Delivery and Form

The notes initially will be represented by one or more permanent global certificates in definitive, fully registered form (the “Global Notes”). The Global Notes will be deposited upon issuance with The Depository Trust Company, New York, New York (“DTC”), and registered in the name of a nominee of DTC in the form of a global certificate.

The Global Notes

DTC has advised us that pursuant to procedures established by it (i) upon the issuance of the Global Notes, DTC or its custodian will credit, on its internal system, the principal amount at maturity of the individual beneficial interests represented by such Global Notes to the respective accounts of persons who have accounts with such depositary and (ii) ownership of beneficial interests in the Global Notes will be shown on, and the transfer of such ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Ownership of beneficial interests in the Global Notes will be limited to persons who have accounts

 

S-26

Table of Contents

with DTC (“participants”) or persons who hold interests through participants holders may hold their interests in the Global Notes directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system.

So long as DTC, or its nominee, is the registered owner or holder of the notes, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Notes for all purposes under the indenture governing the notes. No beneficial owner of an interest in the Global Notes will be able to transfer that interest except in accordance with DTC’s procedures, in addition to those provided for under the indenture with respect to the notes.

Payments of the principal of, premium, if any, and interest (including additional interest) on, the Global Notes will be made to DTC or its nominee, as the case may be, as the registered owner of the Global Notes. None of Airgas, the trustee or any paying agent under the indenture governing the notes will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

DTC has advised us that its present practice is, upon receipt of any payment of principal, premium, if any, and interest (including additional interest) on the Global Notes, to credit immediately participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Notes as shown on the records of DTC. Payments by participants to owners of beneficial interests in the Global Notes held through such participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

Transfers between participants in DTC will be effected in the ordinary way through DTC’s same-day funds system in accordance with DTC rules and will be settled in same-day funds. If a holder requires physical delivery of a certificated security for any reason, including to sell notes to persons in states which require physical delivery of the notes, or to pledge such securities, such holder must transfer its interest in a Global Note, in accordance with the normal procedures of DTC and with the procedures set forth in the indenture governing the notes.

DTC has advised us that it will take any action permitted to be taken by a holder of notes, including the presentation of notes for exchange as described below, only at the direction of one or more participants to whose account the DTC interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the indenture governing the notes, DTC will exchange the Global Notes for certificated securities, which it will distribute to its participants.

DTC has advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “Clearing Agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (“indirect participants”).

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Note among participants of DTC, it is under no obligation to perform such procedures, and such

 

S-27

---

Table of Contents

procedures may be discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Clearstream. Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides Clearstream Participants with, among other things, services for safekeeping, administration, clearance and establishment of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Monetary Institute. Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures to the extent received by DTC for Clearstream.

Euroclear. Euroclear was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several markets in several countries. Euroclear is operated by Euroclear Bank S.AJN.V (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is regulated and examined by the Belgian Banking Commission.

Links have been established among DTC, Clearstream and Euroclear to facilitate the initial issuance of the notes sold outside of the United States and cross-market transfers of the notes associated with secondary market trading.

Although DTC, Clearstream and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform these procedures, and these procedures may be modified or discontinued at any time.

Clearstream and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the total ownership of each of the U.S. agents of Clearstream and Euroclear, as participants in DTC. When notes are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser must send instructions to Clearstream or Euroclear through a participant at least one day prior to settlement. Clearstream or Euroclear, as the case may be, will instruct its U.S. agent to receive notes against payment. After settlement, Clearstream or Euroclear will credit its participant’s account. Credit for the notes will appear on the next day (European time).

 

S-28

Table of Contents

Because settlement is taking place during New York business hours, DTC participants will be able to employ their usual procedures for sending notes to the relevant U.S. agent acting for the benefit of Clearstream or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. As a result, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.

When a Clearstream or Euroclear participant wishes to transfer notes to a DTC participant, the seller will be required to send instructions to Clearstream or Euroclear through a participant at least one business day prior to settlement. In these cases, Clearstream or Euroclear will instruct its U.S. agent to transfer these notes against payment for them. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, with the proceeds back valued to the value date, which would be the preceding day, when settlement occurs in New York. If settlement is not completed on the intended value date, that is, the trade fails, proceeds credited to the Clearstream or Euroclear participant’s account will instead be valued as of the actual settlement date.

You should be aware that you will only be able to make and receive deliveries, payments and other communications involving the notes through Clearstream and Euroclear on the days when those clearing systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States. In addition, because of time zone differences there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States.

Certificated Securities

A Global Note is exchangeable for certificated securities if:

 

•

DTC (1) notifies us that it is unwilling or unable to continue as depositary for the Global Notes or (2) has ceased to be a Clearing Agency registered under the Exchange Act and, in either case, we fail to appoint a successor depositary;

 

•

we, at our option, notify the trustee in writing that we elect to cause the issuance of the notes in certificated form (provided that under current industry practices, DTC would notify participants of our determination, but would only withdraw beneficial interests from a Global Note at the request of participants); or

 

•

there has occurred and is continuing a default or an event of default with respect to the notes.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion summarizes certain U.S. federal income tax consequences of the purchase, ownership and disposition of the notes.

This summary is based on the Internal Revenue Code of 1986, as amended, which we refer to as the “Code,” regulations issued under the Code, judicial authority and administrative rulings and practice, all as of the date hereof and all of which are subject to change. Any such change may be applied retroactively and may adversely affect the U.S. federal tax consequences described in this prospectus supplement. This summary addresses only tax consequences to investors that purchase the notes at initial issuance for the “issue price,” which will equal the first price to the public (not including bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) at which a substantial amount of the notes is sold for money, and own the notes as “capital assets” within the meaning of the Code and not as part of a “straddle” or a “conversion transaction” for U.S. federal income tax purposes, or as part of some other integrated investment.

This summary does not discuss all of the tax consequences that may be relevant to particular investors or to investors subject to special treatment under the U.S. federal income tax laws (such as insurance companies, banks, financial institutions, tax-exempt organizations, retirement plans, regulated investment companies, holders subject to the alternative minimum tax, partnerships or other pass-through entities (or investors in such entities), securities dealers, expatriates or United States persons whose functional currency for tax purposes is not the U.S. dollar). In addition, this summary does not describe any tax consequences arising out of the tax laws of any state, local, foreign or other taxing jurisdiction, any U.S. federal estate or gift tax consequences, or any consequences resulting from the newly enacted Medicare tax on investment income. We have not and do not intend to seek a ruling from the Internal Revenue Service, or the “IRS,” with respect to any matters discussed in this section, and we cannot assure you that the IRS will not challenge one or more of the tax consequences described below.

If any entity treated as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding notes should consult its tax advisers with respect to the tax treatment of holding notes through the partnership.

In certain circumstances, the notes provide for the payment of amounts in excess of stated interest or principal. Our obligation to pay such excess amounts may implicate the provisions of the Treasury regulations relating to “contingent payment debt instruments.” However, the possibility of such excess amounts being paid should not cause the notes to be treated as contingent payment debt instruments if, as of the issue date, such contingency is “remote,” “incidental,” or, in certain circumstances, if it is significantly more likely than not that such contingency will not occur. Although the matter is not free from doubt, we intend to take the position that these contingencies should not cause the notes to be treated as contingent payment debt instruments. This determination will be binding on a holder unless it explicitly discloses its contrary position to the IRS in the manner required by applicable Treasury regulations. However, this determination is inherently factual and we can give you no assurance that our position would be sustained if challenged by the IRS. If the IRS successfully challenged this determination, it could adversely affect the amount, timing and character of the income that a holder must recognize (including, for example, by treating gain recognized by holders upon a disposition of a note as ordinary income and requiring a holder to accrue interest income at a rate higher than the stated interest on the notes). The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. Holders are urged to consult their own tax advisors regarding the potential application of the contingent payment debt regulations to the notes and the consequences thereof.

Persons considering the purchase of the notes should consult their tax advisers concerning the application of the U.S. federal income, estate and gift tax laws to their particular situations as well as any tax consequences of the purchase, ownership and disposition of the notes arising under the laws of any state, local, foreign or other taxing jurisdiction.

Table of Contents

It is expected, and therefore this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes.

U.S. holders

For purposes of this discussion, a “U.S. Holder” means, for U.S. federal income tax purposes, a beneficial owner of a note that is:

 

•

an individual who is a citizen or resident of the United States;

 

•

a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any State or political subdivision thereof or therein (including the District of Columbia);

 

•

an estate whose income is subject to U.S. federal income taxation regardless of its source; or

 

•

a trust if a court within the United States is able to exercise primary supervision over its administration and one or more United States persons have the authority to control all of its substantial decisions, or that was a domestic trust for U.S. federal income tax purposes on August 19, 1996, and has elected to continue to be treated as a domestic trust.

Treatment of interest

Stated interest on the notes will be taxable to a U.S. Holder as ordinary income as the interest accrues or is paid in accordance with the U.S. Holder’s method of tax accounting.

Treatment of dispositions of notes

Upon the sale, exchange, retirement, redemption or other taxable disposition of a note, a U.S. Holder generally will recognize gain or loss equal to the difference between the amount received on such disposition (other than amounts attributable to accrued and unpaid interest, which will be treated as ordinary interest income if not previously included in income) and the U.S. Holder’s tax basis in the note. A U.S. Holder’s tax basis in a note will be, in general, the cost of the note to the U.S. Holder. Gain or loss realized on the sale, exchange, retirement or redemption of a note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of such sale, exchange, retirement or redemption the note has been held for more than one year. For non-corporate U.S. Holders, certain preferential tax rates may apply to gain recognized as long-term capital gain. A U.S. Holder’s ability to deduct capital losses is subject to limitations.

Non-U.S. holders

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of notes that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. Holder.

For purposes of the following discussion, any interest income and any gain realized on the sale, exchange, retirement, redemption or other disposition of the notes will be considered “U.S. trade or business income” if such interest income or gain is effectively connected with the conduct of a trade or business in the United States.

Treatment of interest

A Non-U.S. Holder will not be subject to U.S. federal income or withholding tax in respect of interest income on the notes if each of the following requirements is satisfied:

 

•

the interest is not U.S. trade or business income;

 

•

the Non-U.S. Holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock;

 

S-31

---

Table of Contents

•

the Non-U.S. Holder is not a “controlled foreign corporation” that is actually or constructively related to us;

 

•

the Non-U.S. Holder is not a bank which acquired the note in consideration for an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business; and

 

•

the Non-U.S. Holder provides to us or our paying agent an appropriate statement on a properly executed IRS Form W-8BEN (or substitute form), together with all appropriate attachments, signed under penalties of perjury, identifying the Non-U.S. Holder and stating, among other things, that the Non-U.S. Holder is not a United States person. If a note is held through a securities clearing organization, bank or another financial institution that holds customers’ securities in the ordinary course of its trade or business, this requirement is satisfied if (i) the Non-U.S. Holder provides such a form to the organization or institution and (ii) the organization or institution, under penalties of perjury, certifies to us that it has received such a form from the beneficial owner or another intermediary and furnishes us or our paying agent with a copy.

To the extent these conditions are not met, a 30% withholding tax will apply to interest income on the notes that is not effectively connected income, unless an applicable income tax treaty reduces or eliminates such tax (and the Non-U.S. Holder provides us or our paying agent a properly executed IRS Form W-8BEN (or substitute form)).

If interest is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States, the Non-U.S. Holder will generally be exempt from withholding tax, although to avoid withholding the Non-U.S. Holder must provide an appropriate statement to that effect on an applicable IRS Form W-8 (or substitute form). Non-U.S. Holders should consult their own tax advisors as to whether different rules than those described in the preceding sentence may apply as the result of an applicable income tax treaty.

A Non-U.S. Holder generally will be subject to U.S. federal income tax with respect to all effectively connected interest income from the notes in the same manner as a U.S. Holder, as described above (unless an applicable income tax treaty provides otherwise). A Non-U.S. Holder that is a corporation could be subject to a branch profits tax at a 30% rate (or lower applicable treaty rate) on such holder’s effectively connected earnings and profits attributable to such income.

Treatment of dispositions of notes

Generally, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain realized upon the sale, exchange, retirement, redemption or other disposition of a note unless:

 

•

such holder is an individual present in the United States for 183 days or more in the taxable year of the sale, exchange, retirement, redemption or other disposition and certain other conditions are met, in which case such holder will be subject to a 30% U.S. federal income tax on the gain derived from the sale or other disposition, which may be offset by certain U.S. source capital losses, or

 

•

the gain is U.S. trade or business income, in which case such holder generally will be subject to U.S. federal income tax in the same manner as U.S. Holders, as described above (unless an applicable income tax treaty provides otherwise). Additionally, in such event, Non-U.S. Holders that are corporations could be subject to a 30% (or lower applicable treaty rate) branch profits tax on such holder’s effectively connected earnings and profits attributable to such gain.

Information reporting requirements and backup withholding

When required, we will report to the holders of the notes and the IRS amounts of interest paid on or with respect to the notes and the amount of any tax withheld from such payments. Copies of the information returns reporting such interest and withholding may be made available to the tax authorities in foreign countries under the provisions of an income tax treaty or agreement.

Table of Contents

Certain non-corporate U.S. Holders may be subject to backup withholding (currently at a rate of 28% and scheduled to increase to 31% in 2011). In general, backup withholding will apply to a U.S. Holder only if the U.S. Holder:

 

•

fails to furnish its Taxpayer Identification Number, or TIN, which for an individual would be his or her Social Security Number;

 

•

furnishes an incorrect TIN;

 

•

is notified by the IRS that it is subject to backup withholding because it has failed to properly report payments of interest and dividends;

 

•

under certain circumstances, fails to certify, under penalties of perjury, that it has furnished a correct TIN and has not been notified by the IRS that it is subject to backup withholding for failure to report interest and dividend payments; or

 

•

fails to establish an exemption from backup withholding.

A Non-U.S. Holder may be subject to backup withholding (currently at a rate of 28%) with respect to interest paid on the notes. However, payments of interest to a Non-U.S. Holder will not be subject to backup withholding and related information reporting if the Non-U.S. Holder certifies its non-U.S. status under penalties of perjury (for instance, on an IRS Form W-8 BEN) or satisfies the requirements of an otherwise established exemption. The payment of the proceeds from a disposition (including a retirement or redemption) of notes by a Non-U.S. Holder to or through the U.S. office of any broker, United States or foreign, will be subject to information reporting and possible backup withholding unless the Non-U.S. Holder certifies its non-U.S. status under penalties of perjury or satisfies the requirements of an otherwise established exemption.

If the proceeds from a disposition (including a retirement or redemption) of notes are paid to or through a foreign office of a broker that is not a United States person or a “U.S. related person,” as defined below, they will not be subject to backup withholding or information reporting. If the proceeds are paid to or through a foreign office of a broker that is either a United States person or a “U.S. related person,” they generally will be subject to information reporting. However, no such reporting is required if the holder certifies as to its non-U.S. status under penalties of perjury or the broker has certain documentary evidence in its files as to the holder’s non-U.S. status. Backup withholding will not apply to payments made through the foreign offices of a United States person or U.S. related person.

For purposes of this paragraph, a “U.S. related person” is:

 

•

a “controlled foreign corporation” for U.S. federal income tax purposes;

 

•

a foreign person 50% or more of whose gross income during a specified three-year period is effectively connected with the conduct of a U.S. trade or business; or

 

•

a foreign partnership if one or more of its partners are United States persons who, in the aggregate, hold more than 50% of the income or capital interest of the partnership or if the partnership is engaged in the conduct of a U.S. trade or business.

Backup withholding is not an additional tax and may be refunded or credited against the holder’s U.S. federal income tax liability, provided that certain required information is timely furnished to the IRS.

The federal income tax discussion set forth above is included for general information only and may not be applicable depending upon a holder’s particular situation. Persons considering the purchase of the notes should consult their tax advisers concerning the application of the U.S. federal income, estate and gift tax laws to their particular situations as well as any tax consequences of the purchase, ownership and disposition of the notes arising under the laws of any state, local, foreign or other taxing jurisdiction.

Total		$	250,000,000

The underwriting agreement is subject to a number of terms and conditions and provides that the underwriters must buy all of the notes if they buy any of them. The underwriters will sell the notes to the public when and if the underwriters buy the notes from us.

The underwriters have advised us that they propose initially to offer the notes to the public at the public offering price set forth on the cover of this prospectus supplement, and may offer the notes to certain dealers at such price less a concession not in excess of 0.35% of the principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.25% of the principal amount of the notes to certain other dealers. After the public offering of the notes, the public offering price and other selling terms may be changed. The offering of the notes by the underwriters is subject to receipt and acceptance of any order and subject to the underwriters’ right to reject any order in whole or in part.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts, will be approximately $600,000.

We have agreed to indemnify the several underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act.

The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any marketmaking activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

In connection with the offering of the notes, certain of the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes.

Table of Contents

Specifically, the underwriters may over allot in connection with the offering, creating a short position. In addition, the underwriters may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the price of the notes. Any of these activities may stabilize or maintain the market price of the notes above independent market levels, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market price of the notes. The underwriters will not be required to engage in these activities, and may engage in these activities, and may end any of these activities, at any time without notice.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, including securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Each of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the issuer, for which they received or will receive customary fees and expenses. Specifically, an affiliate of Banc of America Securities LLC is the administrative agent under our New Senior Credit Facility and affiliates of each of the underwriters except Daiwa Capital Markets America Inc. are lenders under our New Senior Credit Facility and, as a result of the prepayment of the loans thereunder, will receive a portion of the net proceeds of this offering. Each of Banc of America Securities LLC and Wells Fargo Securities, LLC were joint lead arrangers and co-book managers under our New Senior Credit Facility.

In addition, Banc of America Securities LLC and Goldman, Sachs & Co. are acting as financial advisors to us in connection with Air Products, Inc.’s tender offer to purchase all of our common stock.

(“SMBCSI”) pursuant to which SMBCSI provides certain advisory and/or other services to DCMA, including services with respect to this offering. In return for the provision of such services by SMBCSI to DCMA, DCMA will pay to SMBCSI a mutually agreed-upon fee.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and such investment and securities activities may involve securities and/or instruments of the issuer.

CONFLICTS OF INTEREST

Affiliates of each of the underwriters except Daiwa Capital Markets America Inc. are lenders under our New Senior Credit Facility. Because the net proceeds from the offering of the notes will be used to repay indebtedness under our New Senior Credit Facility, we expect that more than 5% of the net proceeds will be directed to one or more of such underwriters (or their affiliates), which would be considered a “conflict of interest” under NASD Rule 2720 of the Financial Industry Regulatory Authority, Inc. As such, this offering is being conducted in accordance with the applicable requirements of Rule 2720(a)(1) regarding the underwriting of securities of a company with a member that has a conflict of interest within the meaning of those rules. Pursuant to Rule 2720, the appointment of a qualified independent underwriter is not necessary in connection with this offering, as the offering is of debt securities that are investment grade rated.

DESCRIPTION OF THE DEBT SECURITIES

The following description of the terms of the debt securities sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those debt securities will be described in the prospectus supplement relating to those debt securities. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the prospectus supplement relating thereto and to the following description.

General

The debt securities may be issued from time to time in an unlimited aggregate principal amount and an unlimited number of series. The debt securities will be issued under an indenture between us and U.S. Bank National Association, as trustee, and under a supplemental indenture authorizing the particular series.

The debt securities are unsecured and will have the same rank as all other unsecured and non-subordinated debt of the Company.

We have summarized the material provisions of the indenture below. The summary is not complete. The indenture is incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. The supplemental indenture for each series will be filed or incorporated by reference as an exhibit to the registration statement. You should read the indenture and the applicable supplemental indenture for provisions that may be important to you. The particular terms of any debt securities we offer will be described in the related prospectus supplement, along with any applicable modifications of or additions to the general terms of the debt securities described below and in the indenture. For a description of the terms of any series of debt securities, you should review both the prospectus supplement relating to that series and the description of the debt securities set forth in this prospectus before making an investment decision.

The prospectus supplement relating to a particular series of debt securities will describe to the extent applicable:

(2) the principal amount being offered, and, if a series, the total amount authorized and the total amount outstanding;

(3) any limit upon the aggregate principal amount of such debt securities;

(7) the place or places where the principal of, and premium and interest, if any, on, such debt securities will be payable;

(8) the terms and conditions upon which any such debt security may be redeemed (including the period or periods within which and the price or prices at which such security may be redeemed), in whole or in part, at our option;

(9) any terms for redemption or repurchase pursuant to any sinking fund or analogous provision at the option of a holder;

(10) if other than the principal amount thereof, the portion of the principal amount of such debt securities that will be payable upon acceleration of maturity;

(12) any terms for the attachment to such debt securities of warrants, options or other rights to purchase or sell stock;

(18) any determination of the amount of principal of, or premium or interest, if any, on, any such debt securities to be determined with reference to an index based on a currency or currency unit or units other than that in which such debt securities are stated to be payable or an index based on any other method;

(21) any other terms of any of such debt securities not inconsistent with the indenture.

Form, Exchange, Registration and Transfer

The debt securities will be issued in registered form, without interest coupons. There will be no service charge for any registration of transfer or exchange of the debt securities. However, payment of any transfer tax or similar governmental charge payable for that registration may be required.

Debt securities of any series will be exchangeable for other debt securities of the same series, the same total principal amount and the same terms but in different authorized denominations in accordance with the applicable indenture. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange if its requirements and the requirements of the applicable indenture are met.

The trustee will be appointed as security registrar for the debt securities. If a prospectus supplement refers to any transfer agents we initially designate, we may at any time rescind that designation or approve a change in the

Unless we inform you otherwise in a prospectus supplement, payments on the debt securities will be made in U.S. dollars at the office of the trustee and any paying agent. At our option, however, payments may be made by wire transfer for global debt securities or by check mailed to the address of the person entitled to the payment as it appears in the security register. Unless we inform you otherwise in a prospectus supplement, interest payments may be made to the person in whose name the debt security is registered at the close of business on the record date for the interest payment.

Unless we inform you otherwise in a prospectus supplement, the trustee under the applicable indenture will be designated as the paying agent for payments on debt securities issued under that indenture. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

If the principal of, or any premium or interest on, debt securities of a series is payable on a day that is not a business day, the payment will be made on the following business day. For these purposes, unless we inform you otherwise in a prospectus supplement, a “business day” means each day on which commercial banks and foreign exchange markets settle payments in the place or places where the principal of (and premium, if any) and interest, if any, on the securities of that series are payable, or place of publication. Unless otherwise specified, “business day” shall exclude any day on which commercial banks and foreign exchange markets do not settle payments in London.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to us upon written request any money held by them for payments on the debt securities that remains unclaimed for two years after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Book-Entry Debt Securities

The debt securities of a series may be issued in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. Global debt securities may be issued in either temporary or permanent form. We will describe in the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

Satisfaction and Discharge; Defeasance

At the request of the Company, the indenture will cease to be in effect as to the debt securities of any series (except for certain obligations to register the transfer or exchange of such debt securities and related coupons, if any, and hold moneys for payment of such debt securities and coupons in trust) when either (a) all such debt

securities and coupons have been delivered to the trustee for cancellation or (b) all such debt securities and coupons have become due and payable or will become due and payable at their stated maturity within one year, or are to be called for redemption within one year, and the Company has deposited with the trustee, in trust money, in the currency, currencies or currency unit or units in which such debt securities are payable, in an amount sufficient to pay all the principal of, and premium and interest, if any, on, such debt securities on the dates such payments are due in accordance with the terms of such debt securities.

The Company may defease any series of debt securities and, at its option, either (a) be discharged after 123 days from any and all obligations in respect of such series of debt securities (except for certain obligations to register the transfer of or exchange debt securities and related coupons, replace stolen, lost or mutilated debt securities and coupons, maintain paying agencies and hold moneys for payment in trust) or (b) eliminate the requirement to comply with certain restrictive covenants of the indenture in respect of such series. In order to exercise either defeasance option, the Company must deposit with the trustee in trust, money, or, in the case of debt securities and coupons denominated in U.S. dollars, U.S. treasuries or, in the case of debt securities and coupons denominated in a foreign currency, foreign government securities, which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay in the currency, currencies or currency unit or units in which such debt securities are payable all the principal (including any mandatory sinking fund payments) of, and interest on, such series on the dates such payments are due in accordance with the terms of such series. Among the conditions to the Company exercising any such option, the Company is required to deliver to the trustee an opinion of counsel to the effect that the deposit and related defeasance would not cause the holders of such series to recognize income, gain or loss for United States Federal income tax purposes and that the holders of such series will be subject to United States Federal income tax in the same amounts, in the same manner and at the same times as would have been the case if such option had not been exercised.

Events of Default, Notice and Waiver

The following are events of default under each indenture with respect to any series of debt securities that we may issue:

 

•

default for 30 days in payment of any interest installment when due;

 

•

default in payment of principal of, or premium, if any, on, debt securities of such series when due at their stated maturity, by declaration, when called for redemption or otherwise;

 

•

default for 30 days in the making of any payment for a sinking, purchase or analogous fund provided for in respect of debt securities of such series;

 

•

default for 60 days after notice to the Company by the trustee or by holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series in the performance of any covenant or agreement in the debt securities of such series or in the indenture with respect to debt securities of such series;

 

•

certain events of bankruptcy, insolvency and reorganization; and

 

•

any other event of default provided with respect to the debt securities of such series.

No event of default with respect to a single series of indebtedness issued under the indenture (and any supplemental indentures) necessarily constitutes an event of default with respect to any other series of indebtedness issued thereunder.

The indenture provides that the trustee will, within 90 days after the occurrence of a default with respect to the debt securities of any series, give to the holders of the debt securities of such series notice of all uncured and unwaived defaults known to it; provided that, except in the case of default in the payment of principal of, or premium or interest, if any, on, or a sinking fund installment, if any, with respect to any of the debt securities of

such series, the trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interest of the holders of the debt securities of such series. The term “default” for the purpose of this provision only means the happening of any of the events of default specified above, except that any grace period or notice requirement is eliminated.

The indenture contains provisions entitling the trustee, subject to the duty of the trustee during an event of default to act with the required standard of care, to be indemnified by the holders of the debt securities before proceeding to exercise any right or power under the indenture at the request of holders of the debt securities.

The indenture provides that the holders of a majority in principal amount of the outstanding debt securities of any series may in certain circumstances direct the time, method and place of conducting proceedings for remedies available to the trustee or exercising any trust or power conferred on the trustee in respect of such series.

The indenture includes a covenant that obligates us to file annually with the trustee an officers’ certificate stating whether any default exists and specifying any default that exists.

In certain cases, the holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of such series waive any past default or event of default with respect to the debt securities of such series or compliance with certain provisions of the indenture, except, among other things, a default not theretofore cured in payment of the principal of, or premium or interest, if any, on, any of the debt securities of such series. The holders of a majority in principal amount of a series of outstanding debt securities also have certain rights to rescind any declaration of acceleration with respect to such series after all events of default with respect to such series not arising from such declaration shall have been cured.

Modification of the Indenture

The indenture allows us and the trustee, without the consent of any holders of debt securities, to enter into supplemental indentures for the purposes, among other things, of:

 

•

evidencing the succession of another corporation and the assumption by such corporation of the covenants in the indenture and series of debt securities;

 

•

adding covenants that apply to us;

 

•

adding additional events of default;

 

•

establishing the form or terms of any series of debt securities issued under such supplemental indentures or curing ambiguities or inconsistencies in the indenture; and

 

•

making other provisions that do not adversely affect the interests of the holders of any series of debt securities in any material respect.

The indenture allows us and the trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding debt securities of all affected series (acting as one class), to execute supplemental indentures adding any provisions to or changing or eliminating any of the provisions of the indenture or modifying the rights of the holders of the debt securities of such series. But no supplemental indenture may, without the consent of the holders of all the outstanding debt securities affected thereby, among other things:

(1) change the stated maturity of the principal of, or any installment of principal of or interest on, any debt security;

(2) reduce the principal amount of, the rate of interest on, or any premium payable upon the redemption of, any debt security;

(3) extend the time for payment of interest on the debt securities;

Table of Contents

(4) impair the right to institute suit for the enforcement of any such payment on or after the stated maturity thereof (or, in the case of redemption, on or after the redemption date);

(5) affect adversely the terms, if any, of conversion of any debt security into our stock or other securities or of any other corporation;

(6) reduce the percentage in principal amount of the outstanding debt securities of any series, the consent of whose holders is required for any such supplemental indenture or any waiver (in compliance with certain provisions of the indenture or certain defaults thereunder and their consequences) provided for in the indenture; and

(7) modify any of the foregoing provisions or the provisions for the waiver of certain covenants and defaults, except to increase any applicable percentage of the aggregate principal amount of outstanding debt securities the consent of the holders of which is required or to provide with respect to any particular series the right to condition the effectiveness of any supplemental indenture as to that series on the consent of the holders of a specified percentage of the aggregate principal amount of outstanding debt securities of such series or to provide that certain other provisions of the indenture cannot be modified or waived without the consent of the holder of each outstanding debt security affected thereby.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

Concerning the Trustee

U.S. Bank National Association serves as the trustee under our indenture dated as of May 27, 2010.

PLAN OF DISTRIBUTION

We may sell the debt securities in any of three ways: (i) through underwriters, (ii) through dealers or agents or (iii) directly to a limited number of institutional purchasers or to a single purchaser. The applicable prospectus supplement will set forth the terms of the offering of the debt securities of such series, including the name or names of any underwriters, the purchase price and the proceeds we receive from such sale, any underwriting discounts and other items constituting underwriters’ compensation, any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers and other specific terms of the particular offering. Only the agents or underwriters named in a prospectus supplement are agents or underwriters in connection with the securities being offered by that prospectus supplement.

If we use underwriters in the sale, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase debt securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all the debt securities of a series if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We may sell debt securities directly or through agents designated by us from time to time. Any agent involved in the offer or sale of the debt securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by certain types of institutions to purchase debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of such contracts.

Agents and underwriters may be entitled under agreements entered into with us and/or our subsidiaries to indemnification against certain civil liabilities, including liabilities under the Securities Act, and/or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents and underwriters may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

Each series of debt securities will be a new issue of securities with no established trading market. Any underwriters to whom we sell debt securities for public offering and sale may make a market in such debt securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any debt securities.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

Unless otherwise indicated in a prospectus supplement or confirmation of sale, the purchase price of the securities will be required to be paid in immediately available funds in New York City.
