INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

     The following documents are incorporated by reference in this registration statement:

     (a) The Company’s annual report on Form 10-K for the fiscal year ended March 31, 2006, filed on June 14, 2006 pursuant to Section 13(a) of the Securities Exchange Act of 1934 (the “1934 Act”); and

     (b) All other reports filed by the Company pursuant to Section 13(a) or Section 15(d) of the 1934 Act since the end of the Company’s fiscal year ended March 31, 2006.

     In addition, all documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the 1934 Act, after the date hereof, prior to the end of this offering shall be deemed to be incorporated by reference in this registration statement and to be part hereof from the date of filing such documents.

Item 4. Description of Securities.

     Under the Airgas, Inc. Deferred Compensation Plan II (the “Plan”), the Registrant will provide eligible employees and non-employee directors the opportunity to enter into agreements for the deferral of a specified percentage of their annual compensation and/or bonus award. The obligations of the Registrant under such agreements (the “Obligations”) will be unsecured general obligations of the Registrant to pay the deferred compensation in the future in accordance with the terms of the Plan, and will rank pari passu with other unsecured and unsubordinated indebtedness of the Registrant, from time to time outstanding. The amount of compensation and/or bonus award to be deferred by each participating employee or non-employee director (a “Participant”) will be determined in accordance with the Plan based on elections by each Participant.

     Each Participant’s deferred amounts shall be credited to a bookkeeping account maintained on the books of the Company (an “Account”). Separate sub-accounts may be maintained on the books of the Company to reflect the different distribution elections chosen under the Plan by each Participant. In addition, Participants may make elections as to how their respective Account balances shall be deemed invested among certain options designated by the committee appointed by the Board of Directors of the Company to administer the Plan (the “Committee”). Participant Accounts will be credited or debited to reflect earnings or losses that would have been realized if the deferred amounts actually were invested in accordance with the Participant’s investment elections.

-2-

     Amounts credited to a Participant’s Account will be payable either on a “Specified Date” (see description below), upon the Participant’s separation from service or upon the earlier of such events. A Participant may elect to have distributions made from his or her account in the form of a lump sum or annual, monthly or quarterly installments for a period of between two (2) to fifteen (15) years.

     A Participant may elect, at the beginning of each calendar year, to designate a distribution date (a “Specified Date”) with respect to his or her deferrals for such Plan Year. The Specified Date must occur no earlier than during the third year following the year in which the deferrals designated for distribution were credited to the Participant’s Account. A Participant may elect to further defer the distribution beyond the Specified Date by electing, at least twelve (12) months prior to the Specified Date, a new Specified Date which is at least five (5) years following the previous Specified Date.

     Each Participant shall have the right, at any time, to designate one or more persons or entities as beneficiary (both primary as well as contingent beneficiaries) to whom benefits under the Plan shall be paid in the event of the Participant’s death prior to complete distribution of the Participant’s Account. If any Participant fails to properly designate a beneficiary, if the designation is void, or if the designated beneficiary dies before the Participant or before complete distribution of the Participant’s benefits, the Participant’s beneficiary shall be the Participant’s surviving spouse, or, failing that, the Participant’s estate.

     Upon a finding that a Participant has suffered an unforeseeable emergency, the Committee may, in its sole discretion, cause distribution of all or any portion of the Participant’s Account. However, the amount of such distribution shall be limited to the amount reasonably necessary to meet the Participant’s needs resulting from the unforeseeable emergency (plus the amount necessary to pay any taxes applicable to the distribution).

     There is no trading market for the Obligations. The Obligations are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Any attempt by any person to transfer or assign benefits under the Plan, will be null and void. The Obligations are not convertible into any other security of the Registrant. No trustee has been appointed to take action with respect to the Obligations and each Participant in the Plan will be responsible for enforcing his or her own rights with respect to the Obligations. The Registrant may establish a grantor, or “rabbi,” trust to serve as a source of funds from which it can satisfy the Obligations. Participants in the Plan will have no rights to any assets held by a rabbi trust, except as general creditors of the Registrant. Assets of any rabbi trust will at all times be subject to the claims of the Registrant’s general creditors.

Item 5. Interests of Named Experts and Counsel.

     Not applicable.

-3-

Item 6. Indemnification of Directors and Officers.

     The Delaware General Corporation Law permits the indemnification by a Delaware corporation of its directors, officers, employees, and other agents against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative, or investigative (other than derivative actions which are by or in the right of the corporation) if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was illegal. A similar standard of care is applicable in the case of derivative actions, except the indemnification only extends to expenses (including attorneys’ fees) incurred in connection with defense or settlement of such an action and requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

     The Company’s certificate of incorporation provides that each person who was or is made a party to, or is involved in, any action, suit or proceeding by reason of the fact that he or she is or was a director or officer of the Company (or was serving at the request of the Company as a director, officer, employee or agent for another entity) while serving in such capacity will be indemnified and held harmless by the Company to the full extent authorized or permitted by Delaware law. The certificate also provides that the Company may purchase and maintain insurance and may also create a trust fund, grant a security interest and/or use other means (including establishing letters of credit, surety bonds and other similar arrangements) and may enter into contracts providing for indemnification, to ensure full payment of indemnifiable amounts.

          (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

          (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

          (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the registration statement is on Form S-3, Form S-8, or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

     (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment 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.

     (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

-5-

     (4) If the registrant is a foreign private issuer, to file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Act or Rule 3-19 of Regulation S-X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

Undertakings required by Item 512(b) of Regulation S-K:

     The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to 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.

Undertakings required by Item 512(h) of Regulation S-K:

     Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has 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 registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

     4.2. Timing of Credits; Withholding. A Participant’s Deferrals shall be credited to the sub-Account designated by the Participant as soon as administratively practicable following the last day of the month during which the applicable Deferral would have otherwise been payable to the Participant, or such more frequent period designated by the Committee. Any withholding of taxes or other amounts with respect to Deferrals that is required by local, state or Federal law shall be withheld from the Participant’s non-deferred Compensation to the maximum extent possible, and any remaining amount shall reduce the amount credited to the Participant’s Account in a manner specified by the Committee.

A Participant shall designate, at a time and in a manner acceptable to the Committee, one or more Valuation Funds for his or her Account for the sole purpose of determining the amount of Interest to be credited or debited to such Account. Such election shall designate the portion of his or her Account that shall be allocated among the available Valuation Fund(s), and such election shall apply to each succeeding deferral of Compensation until such time as the Participant shall file a new election with the Committee. Upon notice to the Committee, the Participant may also reallocate the balance in each Account among the available Valuation Funds as of the next succeeding Determination Date.

     4.4. Determination of Accounts. Each Participant’s Account as of each Determination Date shall consist of the balance of the Account as of the immediately preceding Determination Date, adjusted as follows:

          (a) New Deferrals. Each Account shall be increased by any Deferrals credited since such prior Determination Date in the proportion chosen by the Participant.

          (b) Distributions. Each Account shall be reduced by any payment provided for under Article V of the Plan made from that Account since the prior Determination Date. Distributions shall be deemed to have been made proportionally from each of the Valuation Funds maintained within such Account based on the proportion that such Valuation Fund bears to the sum of all Valuation Funds maintained within such Account for that Participant as of the Determination Date immediately preceding the date of payment.

          (c) Interest. Each Account shall be increased or decreased by the Interest credited to such Account since the prior Determination Date as though the balance of that Account as of such prior Determination Date had been invested in the applicable Valuation Funds chosen by the Participant.

          (d) Vesting of Accounts. Each Participant shall be 100% vested in the amounts credited to such Participant’s Account and Interest thereon.

          (b) Default Form. If a Participant fails to specify a form of payment under Section 5.3(a) with respect to any sub-Account, then such sub-Account shall be distributed as a lump sum under Section 5.3(a)(i).

          (c) Revisions. A Participant may revise his or her initial elections under this Section 5.3, but only to the extent such new election satisfies Section 5.4.

     5.4. Revised Distribution Elections. A Distribution Election that changes the timing initially elected in Section 5.2 or the distribution form initially elected in Section 5.3 for any portion of a Participant’s Account (“Revised Distribution Election”) shall be effective only if such Revised Distribution Election (i) is filed no later than 12 months before the date the payments would otherwise be made, (ii) provides that no payment may be made on a date that is before the date which is five years after the date such payment would otherwise have been made under the Distribution Election in force immediately prior to a filing of such Revised Distribution Election, and (iii) is not effective until 12 months after the date it was made. Such Revised Distribution Election may not accelerate any portion of any payment.

     5.5. Unforeseeable Emergency.

The amount of such distribution shall be limited to the amount reasonably necessary to meet the Participant’s needs resulting from the Unforeseeable Emergency (plus an amount necessary to pay any taxes applicable to the distribution), and will not exceed the Participant’s entire vested Account balance. The amount distributed on an Unforeseeable Emergency shall be withdrawn from such Participant’s sub-Accounts in the order and manner designated by the Participant

The Committee may require proof of incompetency, minority, incapacity or guardianship as it may deem appropriate prior to

- 8 -

distribution. Such distribution shall completely discharge the Committee and the Company from all liability with respect to such benefit.

          (d) Effect of Payment. The full payment of the applicable benefit under this Article V shall completely discharge all obligations on the part of the Company to the Participant (and the Participant’s Beneficiary) with respect to the operation of the Plan, and the Participant’s (and Participant’s Beneficiary’s) rights under the Plan shall terminate.

ARTICLE VI — BENEFICIARY DESIGNATION

     6.1. Beneficiary Designation. Each Participant shall have the right, at any time, to designate one (1) or more persons or entities as Beneficiary (both primary as well as contingent beneficiaries) to whom benefits under the Plan shall be paid in the event of the Participant’s death prior to complete distribution of the Participant’s vested Account balance. Each Beneficiary designation shall be in a written form prescribed by the Committee and shall be effective only when filed with the Committee during the Participant’s lifetime.

     6.2. Changing Beneficiary. Any Beneficiary designation may be changed by a Participant without the consent of the previously named Beneficiary by the filing of a new Beneficiary designation with the Committee. Such new filing shall cancel all designations previously filed.

     6.3. No Beneficiary Designation. If any Participant fails to designate a Beneficiary in the manner provided above, if the designation is void, or if the Beneficiary designated by a deceased Participant dies before the Participant or before complete distribution of the Participant’s benefits, the Participant’s Beneficiary shall be the person in the first of the following classes in which there is a survivor:

In no event shall such extension exceed a period of 180 days from receipt of the claim.

- 10 -

render a benefit determination.

     8.3. Review of Claim. Any Claimant whose claim is denied or deemed denied may request a review by notice given in writing to the Committee. Such request must be made within sixty (60) days after receipt by the Claimant of the written notice of denial or within sixty (60) days after a claim is deemed denied. Failure to submit a proper application for appeal within such 60 day period will cause such claim to be deemed permanently denied. The Claimant or his representative shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claim. A document, record or other information shall be deemed “relevant” to a claim in accordance with DOL Reg. §2560.503-1(m)(8).

     8.4. Final Decision. The decision on review shall normally be made within sixty (60) days after the Committee’s receipt of claimant’s claim or request. If an extension of time is required for a hearing or other special circumstances, the Claimant shall be notified and the time limit shall be one hundred twenty (120) days. The extension notice shall indicate: (i) the special circumstances necessitating the extension and (ii) the date by which the Committee expects to render a benefit determination. An adverse benefit decision on appeal shall be written in a manner calculated to be understood by the Claimant and shall set forth: (i) the specific reason or reasons for the adverse determination, (ii) the specific reference to the Plan provisions on which the denial is based, (iii) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the Claimant’s claim (the relevance of a document, record or other information will be determined in accordance with DOL Reg. §2560.503-1(m)(8)) and (iv) a statement of the Claimant’s right to bring a legal action under §502(a) of ERISA.

     8.5. Litigation. In order to operate and administer the claims procedure in a timely and efficient manner, any Claimant whose appeal with respect to a claim for benefits has been denied, and who desires to commence a legal action with respect to such claim, must commence such action in a court of competent jurisdiction within 90 days of receipt of notification of such denial or date of deemed denial. Failure to file such action by the prescribed time will forever bar the commencement of such action.

This Plan is an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of “management or highly-compensated employees” within the meaning of sections 201, 301, and 401 of ERISA, and therefore is exempt from the provisions of Parts 2, 3 and 4 of Title I of ERISA.

     10.2. Company Obligation. The obligation to make benefit payments to any Participant under the Plan shall be an obligation solely of the Company with respect to the deferred Compensation receivable from, and contributions by, the Company and shall not be an obligation of another company.

     10.3. Unsecured General Creditor. Notwithstanding any other provision of the Plan, Participants and Participants’ Beneficiaries shall be unsecured general creditors, with no secured or preferential rights to any assets of the Company or any other party for payment of benefits under the Plan. Any property held by the Company for the purpose of generating the cash flow for benefit payments shall remain its general, unpledged and unrestricted assets. The Company’s obligation under the Plan shall be an unfunded and unsecured promise to pay money in the future.

     10.4. Trust Fund. The Company shall be responsible for the payment of all benefits provided under the Plan. At its discretion, the Company may establish one (1) or more trusts, with such trustees as the Board may approve, for the purpose of assisting in the payment of such benefits. Although such a trust may be irrevocable, its assets shall be held for payment of all the Company’s general creditors in the event of insolvency. To the extent any benefits provided under the Plan are paid from any such trust, the Company shall have no further obligation to pay them. If not paid from the trust, such benefits shall remain the obligation of the Company.

     10.5. Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgements, alimony or separate maintenance owed by a Participant or any other person, nor be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency.

     10.6. Not a Contract of Employment. This Plan shall not constitute a contract of employment between the Company and any Participant. Nothing in the Plan shall give a Participant the right to be retained in the service of the Company or to interfere with the right of the Company to discipline or discharge a Participant at any time.

     10.7. Protective Provisions. A Participant will cooperate with the Company by furnishing any and all information requested by the Company, in order to facilitate the payment

of benefits hereunder, and by taking such physical examinations as the Company may deem necessary and taking such other action as may be requested by the Company.

     10.8. Governing Law. The provisions of the Plan shall be construed and interpreted according to the laws of the Commonwealth of Pennsylvania, without regard to the conflicts of law provisions thereof, except as preempted by Federal law.

     10.9. Validity. If any provision of the Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but the Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein.

     10.10. Notice. Any notice required or permitted under the Plan shall be sufficient if in writing and hand delivered or sent by registered or certified mail. Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification. Mailed notice to the Committee shall be directed to the Company’s address. Mailed notice to a Participant or Beneficiary shall be directed to the individual’s last known address in the Company’s records.

Re: Airgas, Inc. Deferred Compensation Plan II

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a registration statement on Form S-8 (the “Registration Statement”), to be filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended, for the registration of $6,000,000 of deferred compensation obligations that represent unsecured obligations of Airgas, Inc. (“the Company”) to pay deferred compensation in the future (the “Obligations”). The Obligations are to be offered and sold under the Airgas, Inc. Deferred Compensation Plan II (the “Plan”).

     We have acted as counsel for the Company in connection with the Plan and are familiar with the actions taken by the Company related to the Plan. For purposes of this opinion we have examined the Plan and such other documents, records, certificates and other instruments and such matters of law as we have deemed necessary or appropriate for the purposes of the opinion expressed herein.

     Based on the foregoing, we are of the opinion that, when issued pursuant to the terms of the Plan, the Obligations will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and the terms of the Plan, except as enforceability (i) may be limited by bankruptcy, insolvency, reorganization or other similar laws affecting creditors’ rights generally, and (ii) is subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

     We hereby consent to the filing of this opinion as an exhibit to the Registration Statement.

     It is understood that this opinion is to be used only in connection with the offer and sale of the Obligations while the Registration Statement is in effect.

Very truly yours,
