This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the “Commission”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), utilizing a “shelf” registration process.

FORWARD-LOOKING STATEMENTS
 
This prospectus and the documents incorporated by reference herein 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 expectation that fiscal 2010 second quarter net earnings will range from $0.64 to $0.69 per diluted share; the Company’s expectation that fiscal 2010 earnings will range from $2.65 to $2.85 per diluted share and that its overall effective tax rate for fiscal 2010 will range from 39.0% to 39.5% of pre-tax earnings; the continued weak business climate; our identification of an additional $12 million of annual expense reductions to be fully implemented by the end of the second quarter; our realization of $45 million in annual expense reductions and $10 million of additional expected annual savings in fiscal 2010 from ongoing efficiency initiatives; the Company’s ability and intention to refinance principal payments on its outstanding term loans with borrowings under its long-term revolving credit facilities; the Company’s evaluation of its trade receivable securitization agreement and bank arrangements; the Company’s expectation that its accounts receivable securitization will be available as a source of funds through its expiration date in March 2010; the Company’s belief that if the accounts receivable securitization was not available as a source of funds that it could secure an alternate source of funds; 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 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 due to lower sales, higher product costs and/or higher operating expenses than that forecasted by the Company; continued weakening of the economy 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 production and sales of specialty gases and other products; higher or lower overall tax rates in fiscal 2010 than that estimated by the Company resulting from changes in tax laws, reserves and other estimates; increase 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; the Company’s inability to continue sales of strategic products in markets growing faster than GDP; 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; the inability to refinance payments on the term loans due to a lack of availability under the revolving credit facilities; limitations on the Company’s borrowing capacity dictated by the Senior Credit Facility; our continued ability to access credit markets on satisfactory terms; the impact of tightened credit markets on our customers; the impact of changes in tax and fiscal policies and laws; the extent and duration of current recessionary trends in the U.S. economy; potential disruption to the Company’s business from integration problems associated with acquisitions; the Company’s success in implementing and continuing its cost reduction program; the Company’s ability to successfully identify, consummate and integrate acquisitions to achieve anticipated acquisition synergies; potential liabilities arising from withdrawals from the Company’s assumed multi-employer pension plans; the inability to pay dividends as a result of loan covenant restrictions; the inability to manage interest rate exposure; the potential reduction in the availability of the Company’s securitization agreement; higher or lower interest expense than that estimated by the Company due to changes in debt levels or increases in interest rates performance by counterparties related to interest rate swap agreements; the effects of competition from independent distributors and vertically integrated gas producers on products, pricing and sales growth; changes in product prices from

DESCRIPTION OF THE DEBT SECURITIES AND GUARANTEES
 
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 under the indenture in an unlimited aggregate principal amount and an unlimited number of series. The indenture will be qualified under the Trust Indenture Act of 1939.
 
The debt securities are unsecured and will have the same rank as all other unsecured and non-subordinated debt of the Company.
 
The following summaries of material provisions of the notes and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements related to the debt securities that we sell under this prospectus, as well as the complete indentures that contain the terms of the debt securities.
 
The prospectus supplement relating to the series of debt securities which it offers describes to the extent applicable:
 
(1)  the title of the debt securities of such series;
 
(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;
 
(4)  whether or not we will issue the series of debt securities in global form and, if so, the terms and who the depositary will be;
 
(5)  the date or dates on which such debt securities will mature or the method of determination of such date or dates;
 
(6)  the rate or rates, or the method of determination thereof, at which such debt securities will bear interest, if any, the date or dates from which such interest will accrue, the date or dates such interest will be payable and, for registered debt securities, the regular record dates;
 
(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;
 
(11)  any terms for conversion of the debt securities into other securities of the Company or any other corporation at the option of a holder;
 
(12)  any terms for the attachment to such debt securities of warrants, options or other rights to purchase or sell stock or other securities of the Company;


6


Table of Contents

(13)  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 (debt securities subject to such provisions being referred to as “Original Issue Discount Securities”);
 
(14)  any covenants limiting or otherwise restricting our ability or the ability of our subsidiaries to take any action or measures;
 
(15)  any deletions or modifications of, or additions to, the events of default under the indenture with respect to such debt securities;
 
(16)  if other than U.S. dollars, the currency, currencies or currency unit or units in which such debt securities will be denominated and in which the principal of, and premium and interest, if any, on, such securities will be payable and related restrictions;
 
(17)  whether, and the terms and conditions on which, the Company or a holder may elect that, or the other circumstances under which, payment of principal of, or premium or interest, if any, on, such debt securities is to be made in a currency or currencies or currency unit or units other than that in which such debt securities are denominated;
 
(18)  any matter of determining 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;
 
(19)  whether such debt securities will be issued in fully registered form without coupons or in bearer form with or without coupons, or any combination thereof, whether such debt securities will be issued in the form of one or more global securities and whether such debt securities are to be issuable in temporary global form or definitive global form;
 
(20)  whether and under what circumstances the Company will pay additional amounts to any holder of such debt securities who is not a United States person in respect of any tax, assessment or governmental charge withheld or deducted and, if so, whether and on what terms the Company will have the option to redeem such debt securities rather than pay any additional amounts; and
 
(21)  any other terms of any of such debt securities not inconsistent with the indenture.
 
Subsidiary Guarantees
 
If specified in the prospectus supplement, certain of our subsidiaries (our “Subsidiary Guarantors”) will guarantee the debt securities of a series.
 
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 location through which any transfer agent acts. We are required to maintain an office or agency for transfers and exchanges in each place of payment. We may at any time designate additional transfer agents for any series of debt securities.

Table of Contents

In the case of any redemption, we will not be required to register the transfer or exchange of:
 
  •  any debt security during a period beginning 15 business days prior to the mailing of the relevant notice of redemption or repurchase and ending on the close of business on the day of mailing of such notice; or
 
  •  any debt security that has been called for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part.
 
Payment and Paying Agents
 
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.

Table of Contents

The Company may defease any series of debt securities and, at its option, either (a) be discharged after 90 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)  reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon acceleration of the maturity thereof;
 
(4)  change any place of payment where, or the currency, currencies or currency unit or units in which, any debt security or any premium or interest thereon is payable;
 
(5)  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);
 
(6)  affect adversely the terms, if any, of conversion of any debt security into our stock or other securities or of any other corporation;

Table of Contents

(7)  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;
 
(8)  change any obligation, with respect to outstanding debt securities of a series, to maintain an office or agency in the places and for the purposes specified in the indenture for such series; and
 
(9)  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.

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 of 1933, 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 your 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.

Item 15.   Indemnification of Directors and Officers
 
Delaware Corporation
 
Section 145 of the Delaware General Corporation Law (“DGCL”) permits Airgas, and the other registrants incorporated in Delaware, to indemnify any of their respective directors or officers against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement, incurred in defense of any action (other than an action by or in the rights) arising by reason of the fact that he is or was an officer or director of the registrant if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of such registrant and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 also permits the registrant to indemnify any such officer or director against expenses incurred in an action by or in the right of the registrant if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the registrant, except in respect of any matter as to which such person is adjudged to be liable to the registrant, in which case court approval must be sought for indemnification. This statute requires indemnification of such officers and directors against expenses to the extent they may be successful in defending any such action. This statute provides that it is not exclusive of other indemnification that may be granted by the registrant’s by-laws, a vote of stockholders or disinterested directors, agreement or otherwise. The statute permits purchase of liability insurance by the registrant on behalf of officers and directors, and the registrants have purchased such insurance.
 
Article VII of Airgas, Inc.’s bylaws requires indemnification to the fullest extent permitted by, and in the manner permissible under, the laws of the State of Delaware to any person made, or threatened to be made, a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director or officer of Airgas, Inc. or any predecessor of Airgas, Inc., or served any other enterprise as a director or officer at the request of Airgas, Inc. or any predecessor of Airgas, Inc. The indemnification provided for in Article VII is expressly not exclusive of any other rights to which any director or officer may be entitled apart from the provisions of this Article.
 
The bylaws of the following subsidiaries of the Company generally provide for similar indemnification terms as those provided in the Company’s bylaws: Airgas Carbonic, Inc., Airgas-East, Inc., Airgas-Great Lakes, Inc., Airgas Investments, Inc., Airgas Merchant Holdings, Inc., Airgas-Mid America, Inc., Airgas-Mid South, Inc., Airgas-Nor Pac, Inc., Airgas-North Central, Inc., Airgas-Northern California & Nevada, Inc.,

in the proceeding if he conducted himself in good faith and he reasonably believed, in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests, in all other cases that his conduct was at least not opposed to its best interests and, in the case of any criminal proceeding, that he had no reasonable cause to believe his conduct was unlawful.

No indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that such person, despite adjudication of liability but in view of all the circumstances of the case, is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

(4)  That, for the purpose of determining liability under the Securities Act to any purchaser:
 
(i) If the registrant is relying on Rule 430B.
 
(A)  Each prospectus filed by the registrants pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
 
(B)  Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
 
(5)  That, for the purpose of determining liability of the registrants under the Securities Act to any purchaser in the initial distribution of the securities:
 
The undersigned registrants undertake that in a primary offering of securities of the undersigned registrants pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrants will be sellers to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
(i)  Any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;
 
(ii)  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrants or used or referred to by the undersigned registrants;
 
(iii)  The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or its securities provided by or on behalf of the undersigned registrants; and
 
(iv)  any other communication that is an offer in the offering made by the undersigned registrants to the purchaser.
 
(b)  The undersigned registrants hereby undertake that, for purposes of determining any liability under the Securities Act, each filing of the registrants’ annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(c)  Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrants pursuant to the provisions described in Item 15 above (other than through the liability insurance referred to therein), or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission, such

indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by a director, officer or controlling person in the successful defense of any action, suit or proceeding and other than through such liability insurance) is asserted by such officer, director or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether or not such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
 
(d)  The undersigned registrants hereby undertake to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.
