Subject to the terms and conditions hereof and in reliance upon the representations and warranties set forth herein, each U.S. Revolving Lender severally agrees to make available to Airgas such U.S. Revolving Lender’s Applicable Percentage of revolving credit loans requested by Airgas in U.S. Dollars (“U.S. Revolving Loans”) from time to time from the Closing Date until the Maturity Date, or such earlier date as the U.S. Revolving Commitments shall have been terminated as provided herein; provided, however, that the aggregate principal amount of outstanding U.S. Revolving Loans shall not exceed SIX HUNDRED FIFTY MILLION U.S. DOLLARS ($650,000,000) (as such aggregate maximum amount may be increased or reduced from time to time as provided in Section 4.4, the “U.S. Revolving Committed Amount”); provided, further, (i) with regard to each U.S. Revolving Lender individually, such U.S. Revolving Lender’s outstanding U.S. Revolving Loans shall not exceed such U.S. Revolving Lender’s Applicable Percentage of the U.S. Revolving Committed Amount and (ii) with regard to the U.S. Revolving Lenders collectively, the aggregate principal amount of outstanding U.S. Revolving Loans plus the aggregate principal amount of outstanding U.S. Swingline Loans plus the aggregate U.S. LOC Obligations outstanding shall not exceed the U.S. Revolving Committed Amount.

For purposes hereof, Eurocurrency Loans with different Interest Periods shall be considered as separate Eurocurrency Loans, even if they begin on the same date, although borrowings, extensions and conversions may, in accordance with the provisions hereof, be combined at the end of existing Interest Periods to constitute a new Eurocurrency Loan with a single Interest Period.

(ii) the issuance of such U.S. Letter of Credit would violate one or more policies of the U.S. Issuing Lender applicable to letters of credit generally;

(iii) the U.S. Issuing Lender does not as of the issuance date of such requested U.S. Letter of Credit issue letters of credit in the requested currency; or

(iv) any Lender is at that time a Defaulting Lender, unless the U.S. Issuing Lender has entered into arrangements, including the delivery of Cash Collateral, reasonably satisfactory to the U.S. Issuing Lender (in its sole discretion) with Airgas or such U.S. Revolving Lender to eliminate the U.S. Issuing Lender’s actual or potential Fronting Exposure (after giving effect to Section 4.16(a)(iv)) with respect to the Defaulting Lender arising from either the U.S. Letter of Credit then proposed to be issued or that U.S. Letter of Credit and all other U.S. LOC Obligations as to which the U.S. Issuing Lender has actual or potential Fronting Exposure, as it may elect in its reasonable discretion.

Such request shall be submitted using the form of letter of credit application in use by the U.S. Issuing Lender at such time. In the case of a request for an initial issuance of a U.S. Letter of Credit, such letter of credit application shall specify in form and detail reasonably satisfactory to the U.S. Issuing Lender: (A) the proposed issuance date of the requested U.S. Letter of Credit (which shall be a Business Day); (B) the amount and currency thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; (G) the purpose and nature of the requested U.S. Letter of Credit; and (H) such other matters as the U.S. Issuing Lender may reasonably require.

Additionally, Airgas shall furnish to the U.S. Issuing Lender and the Agent such other documents and information pertaining to such requested U.S. Letter of Credit issuance or amendment, including any LOC Documents, as the U.S. Issuing Lender or the Agent may reasonably require.

(ii) Promptly after receipt of any letter of credit application, the U.S. Issuing Lender will confirm with the Agent (by telephone or in writing) that the Agent has received a copy of such letter of credit application from Airgas and, if not, the U.S. Issuing Lender will provide the Agent with a copy thereof. Unless the U.S. Issuing Lender has received written notice from any Lender, the Agent or any Borrower, at least one Business Day prior to the requested date of issuance of the applicable U.S. Letter of Credit, that one or more applicable conditions contained in Article V shall not be satisfied, then, subject to the terms and conditions hereof, the U.S. Issuing Lender shall, on the requested date, issue a U.S. Letter of Credit for the account of Airgas or the applicable Subsidiary or enter into the applicable amendment, as the case may be, in each case in accordance with the U.S. Issuing Lender’s usual and customary business practices.

(iii) Promptly after its delivery of any U.S. Letter of Credit or any amendment to a U.S. Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the U.S. Issuing Lender will also deliver to Airgas and the Agent a true and complete copy of such U.S. Letter of Credit or amendment. Airgas shall promptly examine a copy of each U.S. Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with Airgas’ instructions or other irregularity, Airgas will immediately notify the U.S. Issuing Lender.

(iv) If Airgas so requests in any applicable letter of credit application, the U.S. Issuing Lender may, in its sole discretion, agree to issue a U.S. Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the U.S. Issuing Lender to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such U.S. Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such U.S. Letter of Credit is issued. Unless otherwise directed by the U.S. Issuing Lender, Airgas shall not be required to make a specific request to the U.S. Issuing Lender for any such extension. Once an Auto-Extension Letter of Credit has been issued, the U.S. Revolving Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the extension of such

Letter of Credit at any time to an expiry date not later than the Maturity Date; provided, however, that the U.S. Issuing Lender shall not permit any such extension if (A) the U.S. Issuing Lender has determined that it would not be permitted, or would have no obligation, at such time to issue such U.S. Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of Section 2.2(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the Non-Extension Notice Date (1) from the Agent that the Required U.S. Lenders have elected not to permit such extension or (2) from the Agent, any Lender or any Borrower that one or more of the applicable conditions specified in Section 5.2 is not then satisfied, and in each case directing the U.S. Issuing Lender not to permit such extension.

(v) The U.S. Issuing Lender will, at least quarterly and more frequently upon request, disseminate to the Agent and each of the U.S. Revolving Lenders a detailed report specifying the U.S. Letters of Credit which are then issued and outstanding and any activity with respect thereto which may have occurred since the date of the prior report, and including therein, among other things, the beneficiary, the face amount, expiry date as well as any payment or expirations which may have occurred.

(c) Participation. Each U.S. Revolving Lender, upon issuance of a U.S. Letter of Credit (or, in the case of each Existing U.S. Letter of Credit, on the Closing Date), shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase without recourse a risk participation from the U.S. Issuing Lender in such U.S. Letter of Credit and the obligations arising thereunder, in each case in an amount equal to its Applicable Percentage of the amount such U.S. Letter of Credit and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the U.S. Issuing Lender therefor and discharge when due, its Applicable Percentage of the obligations arising under such U.S. Letter of Credit. Without limiting the scope and nature of each U.S. Revolving Lender’s participation in any U.S. Letter of Credit, to the extent that the U.S. Issuing Lender has not been reimbursed as required hereunder or under any such U.S. Letter of Credit, each such U.S. Revolving Lender shall pay to the U.S. Issuing Lender its Applicable Percentage of such unreimbursed drawing in U.S. Dollars and in Same Day Funds on the day of notification by the U.S. Issuing Lender of an unreimbursed drawing pursuant to the provisions of Section 2.2(d). The obligation of each U.S. Revolving Lender to so reimburse the U.S. Issuing Lender shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of Airgas to reimburse the U.S. Issuing Lender under any U.S. Letter of Credit, together with interest as hereinafter provided.

(d) Drawings and Reimbursement. Upon receipt from the beneficiary of any U.S. Letter of Credit of any notice of drawing under such U.S. Letter of Credit, the U.S. Issuing Lender shall notify Airgas and the Agent thereof. Unless Airgas shall immediately notify the U.S. Issuing Lender that Airgas intends to otherwise reimburse the U.S. Issuing Lender for such drawing, Airgas shall be deemed to have requested that the U.S. Revolving Lenders make a U.S. Revolving Loan in the U.S. Dollar Equivalent amount of the drawing as provided in Section 2.2(e) on the related U.S. Letter of Credit, the proceeds of which will be used to satisfy the related reimbursement obligations. Airgas promises to reimburse the U.S. Issuing Lender on the day (or the next succeeding Business Day if Airgas receives notice of the drawing after 12:00 noon on such day) of drawing under any U.S. Letter of Credit (either with the proceeds of a U.S. Revolving Loan obtained hereunder or otherwise) in Same Day Funds; in the case of a drawing under a U.S. Letter of Credit denominated in a Foreign Currency with respect to which Airgas has notified the U.S. Issuing Lender as provided in the immediately preceding sentence, such reimbursement shall be made in the applicable Foreign Currency, unless (A) the U.S. Issuing Lender (at its option) shall have specified in such notice that it will require reimbursement in U.S. Dollars, or (B) in the absence of any such requirement for reimbursement in U.S. Dollars, Airgas shall have notified the U.S. Issuing Lender promptly following receipt of the notice of drawing that Airgas will reimburse the U.S. Issuing Lender in U.S. Dollars. If Airgas shall fail to reimburse

the U.S. Issuing Lender as provided hereinabove, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Default Rate. Airgas’ reimbursement obligations hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of setoff, counterclaim or defense to payment Airgas may claim or have against the U.S. Issuing Lender, the Agent, the U.S. Revolving Lenders, the beneficiary of the U.S. Letter of Credit drawn upon or any other Person, including without limitation any defense based on: (i) any failure of Airgas to receive consideration, (ii) the legality, validity, regularity or unenforceability of a U.S. Letter of Credit, (iii) any draft, demand, certificate or other document presented under a U.S. Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect, (iv) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under a U.S. Letter of Credit; or (v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, Airgas. The Agent will promptly notify the U.S. Revolving Lenders of the U.S. Dollar Equivalent amount of any unreimbursed drawing under any U.S. Letter of Credit, and each U.S. Revolving Lender shall promptly pay to the Agent for the account of the U.S. Issuing Lender in U.S. Dollars and in immediately available funds, the amount of such U.S. Revolving Lender’s Applicable Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such U.S. Revolving Lender from the U.S. Issuing Lender if such notice is received at or before 2:00 P.M., otherwise such payment shall be made at or before 12:00 NOON on the Business Day next succeeding the day such notice is received. If such U.S. Revolving Lender does not pay such amount to the U.S. Issuing Lender in full upon such request, such U.S. Revolving Lender shall, on demand, pay to the Agent for the account of the U.S. Issuing Lender interest on the unpaid amount during the period from the date of such drawing until such U.S. Revolving Lender pays such amount to the U.S. Issuing Lender in full at a rate per annum equal to, if paid within two (2) Business Days of the date that such U.S. Revolving Lender is required to make payments of such amount pursuant to the preceding sentence, the Federal Funds Rate and thereafter at a rate equal to the U.S. Base Rate. Each U.S. Revolving Lender’s obligation to make such payment to the U.S. Issuing Lender, and the right of the U.S. Issuing Lender to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Credit Agreement or the Commitments hereunder, the existence of a Default or Event of Default or the acceleration of the obligations of Airgas hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a U.S. Revolving Lender to the U.S. Issuing Lender, such U.S. Revolving Lender shall, automatically and without any further action on the part of the U.S. Issuing Lender or such U.S. Revolving Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the U.S. Issuing Lender) in the related unreimbursed drawing portion of the U.S. LOC Obligation and in the interest thereon and in the related U.S. LOC Documents, and shall have a claim against Airgas with respect thereto. Any notice given by the U.S. Issuing Lender or the Agent pursuant to this Section 2.2(d) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(e) Repayment with U.S. Revolving Loans. On any day on which Airgas shall have requested, or shall be deemed to have requested, a U.S. Revolving Loan advance to reimburse a drawing under a U.S. Letter of Credit, the Agent shall give notice to the U.S. Revolving Lenders that a U.S. Revolving Loan has been requested or deemed requested by Airgas to be made in connection with a drawing under a U.S. Letter of Credit, in which case a U.S. Revolving Loan advance comprised of U.S. Base Rate Loans (or Eurocurrency Loans to the extent Airgas has complied with the procedures of Section 2.1(b)(i) with respect thereto) shall be immediately made to Airgas by all U.S. Revolving Lenders (notwithstanding any termination of the Commitments pursuant to Section 9.2) pro rata based on the respective Applicable Percentages of the U.S. Revolving Lenders and the proceeds thereof shall be paid directly to the U.S. Issuing Lender for application to the respective U.S. LOC Obligations. Each U.S. Revolving Lender hereby irrevocably agrees to make its Applicable Percentage of each such U.S. Revolving Loan immediately upon any such request or deemed request in the amount, in the manner and on the date specified in the preceding

sentence notwithstanding (i) the amount of such borrowing may not comply with the minimum amount for advances of U.S. Revolving Loans otherwise required hereunder, (ii) whether any conditions specified in Section 5.2 are then satisfied, (iii) whether a Default or an Event of Default then exists, (iv) failure for any such request or deemed request for U.S. Revolving Loan to be made by the time otherwise required hereunder, (v) whether the date of such borrowing is a date on which U.S. Revolving Loans are otherwise permitted to be made hereunder or (vi) any termination of the Commitments relating thereto immediately prior to or contemporaneously with such borrowing. In the event that any U.S. Revolving Loan cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code with respect to Airgas), then each U.S. Revolving Lender hereby agrees that it shall forthwith purchase (as of the date such borrowing would otherwise have occurred, but adjusted for any payments received from Airgas on or after such date and prior to such purchase) from the U.S. Issuing Lender in U.S. Dollars such participation in the outstanding U.S. LOC Obligations as shall be necessary to cause each U.S. Revolving Lender to share in such U.S. LOC Obligations ratably (based upon the respective Applicable Percentages of the U.S. Revolving Lenders), provided that at the time any purchase of participation pursuant to this sentence is actually made, the purchasing U.S. Revolving Lender shall be required to pay to the U.S. Issuing Lender, to the extent not paid to the U.S. Issuing Lender by Airgas in accordance with the terms of Section 2.2(d), interest on the principal amount of participation purchased for each day from and including the day upon which such borrowing would otherwise have occurred to but excluding the date of payment for such participation, at the rate equal to, if paid within two (2) Business Days of the date of the U.S. Revolving Loan advance, the Federal Funds Rate, and thereafter at a rate equal to the U.S. Base Rate. Until each U.S. Revolving Lender funds its U.S. Revolving Loan or purchases its participation pursuant to this Section 2.2(e) to reimburse the U.S. Issuing Lender for any amount drawn under any U.S. Letter of Credit, interest in respect of such U.S. Revolving Lender’s Applicable Percentage of such amount shall be solely for the account of the U.S. Issuing Lender.

(f) Repayment of Participations.

(i) At any time after the U.S. Issuing Lender has made a payment under any U.S. Letter of Credit and has received from any U.S. Revolving Lender such U.S. Revolving Lender’s payment of its participation interest in respect of such payment in accordance with Section 2.2(e), if the Agent receives for the account of the U.S. Issuing Lender any payment in respect of the related unreimbursed drawing or interest thereon (whether directly from Airgas or otherwise, including proceeds of cash collateral applied thereto by the Agent), the Agent will distribute to such U.S. Revolving Lender its Applicable Percentage thereof in U.S. Dollars and in the same funds as those received by the Agent.

(ii) If any payment received by the Agent for the account of the U.S. Issuing Lender pursuant to Section 2.2(e) is required to be returned under any of the circumstances described in Section 11.20 (including pursuant to any settlement entered into by the U.S. Issuing Lender in its discretion), each U.S. Revolving Lender shall pay to the Agent for the account of the U.S. Issuing Lender its Applicable Percentage thereof on demand of the Agent, plus interest thereon from the date of such demand to the date such amount is returned by such U.S. Revolving Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the U.S. Revolving Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Credit Agreement.

(g) Designation of Subsidiaries as Account Parties. Notwithstanding anything to the contrary set forth in this Credit Agreement, including without limitation Section 2.2(a), a U.S. Letter of Credit issued hereunder may contain a statement to the effect that such U.S. Letter of Credit is issued for the account of a Subsidiary of Airgas, provided that notwithstanding such statement, Airgas shall be the actual account party for all purposes of this Credit Agreement for such U.S. Letter of Credit and such statement shall not affect Airgas’ reimbursement obligations hereunder with respect to such U.S. Letter of Credit.

(h) Renewal, Extension. The renewal or extension of any U.S. Letter of Credit shall, for purposes hereof, be treated in all respects the same as the issuance of a new U.S. Letter of Credit hereunder.

(i) Applicability of ISP and UCP. Unless otherwise expressly agreed by the U.S. Issuing Lender and Airgas when a U.S. Letter of Credit is issued (including any such agreement applicable to an Existing U.S. Letter of Credit), (i) the rules of the ISP shall apply to each standby U.S. Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to each trade U.S. Letter of Credit.

(j) Indemnification; Nature of U.S. Issuing Lender’s Duties.

(i) Airgas agrees to indemnify and hold harmless the U.S. Issuing Lender, each other U.S. Revolving Lender, the Agent and each of their respective officers, directors, affiliates, employees or agents (the “Indemnitees”) from and against any and all claims and damages, losses, liabilities, costs and expenses which the Indemnitees may incur (or which may be claimed against any Indemnitee) by any Person by reason of or in connection with the issuance or transfer of or payment or failure to pay under any U.S. Letter of Credit; provided that Airgas shall not be required to indemnify any Indemnitee for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, (A) caused by the willful misconduct or gross negligence of such Indemnitee in determining whether a request presented under any U.S. Letter of Credit complied with the terms of such U.S. Letter of Credit or (B) caused by the U.S. Issuing Lender’s failure to pay under any U.S. Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such U.S. Letter of Credit (unless such payment is prohibited by any law, regulation, court order or decree).

(ii) Airgas agrees, as between Airgas and the U.S. Issuing Lender, Airgas shall assume all risks of the acts, omissions or misuse of any U.S. Letter of Credit by the beneficiary thereof.

(iii) The U.S. Issuing Lender shall not, in any way, be liable for any failure by the U.S. Issuing Lender or anyone else to pay any drawing under any U.S. Letter of Credit as a result of any cause beyond the control of the U.S. Issuing Lender.

(iv) Nothing in this Section 2.2(j) is intended to limit the reimbursement obligations of Airgas contained in Section 2.2(d). The obligations of Airgas under this Section 2.2(j) shall survive the termination of this Credit Agreement. No act or omissions of any current or prior beneficiary of a U.S. Letter of Credit shall in any way affect or impair the rights of the U.S. Issuing Lender to enforce any right, power or benefit under this Credit Agreement.

(v) Notwithstanding anything to the contrary contained in this Section 2.2(j), Airgas shall have no obligation to indemnify the U.S. Issuing Lender in respect of any liability incurred by the U.S. Issuing Lender (A) arising out of the gross negligence or willful misconduct of the U.S. Issuing Lender, or (B) caused by the U.S. Issuing Lender’s failure to pay under any U.S. Letter of Credit after presentation to it of a request strictly complying with the terms and conditions of such U.S. Letter of Credit, as determined by a court of competent jurisdiction, unless such payment is prohibited by any law, regulation, court order or decree.

(k) Responsibility of U.S. Issuing Lender. It is expressly understood and agreed that the obligations of the U.S. Issuing Lender hereunder to the U.S. Revolving Lenders are only those expressly set forth in this Credit Agreement and that the U.S. Issuing Lender shall be entitled to assume that the conditions precedent set forth in Section 5.2 have been satisfied unless it shall have acquired actual knowledge that any such condition precedent has not been satisfied; provided, however, that nothing set forth in this Section 2.2 shall be deemed to prejudice the right of any U.S. Revolving Lender to recover from the U.S. Issuing Lender any amounts made available by such U.S. Revolving Lender to the U.S. Issuing Lender pursuant to this Section 2.2 in the event that it is determined by a court of competent jurisdiction that the payment with respect to a U.S. Letter of Credit constituted gross negligence or willful misconduct on the part of the U.S. Issuing Lender. Each Lender and the Borrowers agree that, in paying any drawing under a U.S. Letter of Credit, the U.S. Issuing Lender shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by such U.S. Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the U.S. Issuing Lender, the Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the U.S. Issuing Lender shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the requisite Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or U.S. LOC Document. In furtherance and not in limitation of the foregoing, the U.S. Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the U.S. Issuing Lender shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a U.S. Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(l) Conflict with U.S. LOC Documents. In the event of any conflict between this Credit Agreement and any U.S. LOC Document (including any letter of credit application), this Credit Agreement shall control.

(m) Role of Agent. Airgas and each U.S. Issuing Lender agree to provide the Agent with a copy of any notice or report otherwise required to be furnished by such Person to any other Person pursuant to Sections 2.2(a), 2.2(b) or 2.2(d). Furthermore, all payments required to be made by any U.S. Revolving Lender to a U.S. Issuing Lender pursuant to Section 2.2 shall be made to the Agent, for the account of such U.S. Issuing Lender, and the Agent shall distribute such payments to such U.S. Issuing Lender.

2.3 U.S. Swingline Loan Subfacility.

(a) U.S. Swingline Loans. Subject to the terms and conditions set forth herein and in reliance upon the agreements of the other U.S. Revolving Lenders set forth in this Section 2.3, the U.S. Swingline Lender shall make revolving credit loans requested by Airgas in U.S. Dollars to Airgas (each a “U.S. Swingline Loan” and, collectively, the “U.S. Swingline Loans”) from time to time from the Closing Date until the Maturity Date, unless (x) any U.S. Revolving Lender at such time is a Defaulting Lender and (y) the U.S. Swingline Lender has not entered into arrangements reasonably satisfactory to it with Airgas or such Defaulting Lender to eliminate the U.S. Swingline Lender’s Fronting Exposure with respect to such Defaulting Lender (including by operation of Section 4.16(a)(iv)), in which case the U.S. Swingline Lender may in its discretion, make such U.S. Swingline Loans; provided, however, (i) the aggregate principal amount of U.S. Swingline Loans outstanding at any time shall not exceed the U.S. Swingline Sublimit, and (ii) the aggregate principal amount of outstanding U.S. Revolving Loans plus the aggregate principal amount of outstanding U.S. Swingline Loans plus the aggregate U.S. LOC Obligations outstanding shall not exceed the U.S. Revolving Committed Amount. U.S. Swingline Loans hereunder shall be made as U.S. Base Rate Loans or Quoted Rate U.S. Swingline Loans as Airgas may request in accordance with the provisions of this Section 2.3, and may be repaid and reborrowed in accordance with the provisions hereof.

(b) U.S. Swingline Loan Advances.

(i) Notices; Disbursement. Whenever Airgas desires a U.S. Swingline Loan advance hereunder, a Responsible Officer shall give written notice (or telephone notice promptly confirmed in writing) to the U.S. Swingline Lender not later than 2:00 P.M. on the Business Day of the requested U.S. Swingline Loan advance. Each such notice shall be irrevocable and shall specify (A) that a U.S. Swingline Loan advance is requested, (B) the date of the requested U.S. Swingline Loan advance (which shall be a Business Day) and (C) the principal amount of the U.S. Swingline Loan advance requested. Each U.S. Swingline Loan shall be made as a U.S. Base Rate Loan or a Quoted Rate U.S. Swingline Loan and shall have such maturity date as the U.S. Swingline Lender and Airgas shall agree upon receipt by the U.S. Swingline Lender of any such notice from Airgas. The U.S. Swingline Lender shall credit the funds requested to an Airgas account maintained with the Swingline Lender by 3:00 P.M. on the Business Day of the requested borrowing.

(ii) Minimum Amounts. Each U.S. Swingline Loan advance shall be in a minimum principal amount of $100,000 and in integral multiples thereof (or the remaining amount of the U.S. Swingline Sublimit, if less).

(iii) Repayment of U.S. Swingline Loans. Airgas promises to pay the principal amount of all U.S. Swingline Loans on the earlier of (A) the maturity date agreed to by the U.S. Swingline Lender and Airgas with respect to such U.S. Swingline Loan (which maturity date shall not be a date more than thirty (30) days from the date of advance thereof) or (B) the Maturity Date. The U.S. Swingline Lender may, at any time, in its sole discretion, by written notice to Airgas and the U.S. Revolving Lenders, demand repayment of its U.S. Swingline Loans by way of a U.S. Revolving Loan advance, in which case Airgas shall be deemed to have requested a U.S. Revolving Loan advance comprised solely of U.S. Base Rate Loans in the amount of such U.S. Swingline Loans; provided, however, that any such demand (if not made prior thereto) shall be deemed to have been given one Business Day prior to the Maturity Date and on the date of the occurrence of any Event of Default described in Section 9.1 (or if such date is not a Business Day, the first Business Day succeeding such date) and upon acceleration of the Obligations and the exercise of remedies in accordance with the provisions of Section 9.2. Each U.S. Revolving Lender hereby irrevocably agrees to make its Applicable Percentage of each such U.S. Revolving Loan in the amount, in the manner and on the date specified in the preceding sentence notwithstanding (I) the amount of such borrowing may not comply with the minimum amount for advances of U.S. Revolving Loans otherwise required hereunder, (II) whether any conditions specified in Section 5.2 are then satisfied, (III) whether a Default or an Event of Default then exists, (IV) failure of any such request or deemed request for a U.S. Revolving Loan to be made by the time otherwise required hereunder, (V) whether the date of such borrowing is a date on which U.S. Revolving Loans are otherwise permitted to be made hereunder or (VI) any termination of the Commitments relating thereto immediately prior to or contemporaneously with such borrowing. In the event that any U.S. Revolving Loan cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code with respect to Airgas), then each U.S. Revolving Lender hereby agrees that it shall forthwith purchase (as of the date such borrowing would otherwise have occurred, but adjusted for any payments received from Airgas on or after such date and prior to such purchase) from the U.S. Swingline Lender such participations in the outstanding U.S. Swingline Loans as shall be necessary to cause each U.S. Revolving Lender to share in such U.S. Swingline Loans ratably based upon its Applicable Percentage of the U.S. Revolving Committed Amount, provided that (A) all interest payable on the U.S. Swingline Loans shall be for the account of the U.S. Swingline Lender until the date as of which the respective participation is

purchased and (B) at the time any purchase of participations pursuant to this sentence is actually made, the purchasing U.S. Revolving Lender shall be required to pay to the U.S. Swingline Lender, to the extent not paid to the U.S. Swingline Lender by Airgas in accordance with the terms of Section 2.3(c)(ii), interest on the principal amount of participation purchased for each day from and including the day upon which such borrowing would otherwise have occurred to but excluding the date of payment for such participation, at the rate equal to the Federal Funds Rate.

(c) Interest on U.S. Swingline Loans. (i) Subject to the provisions of Section 4.1, each U.S. Swingline Loan shall bear interest as follows:

(A) U.S. Base Rate Loans. If such U.S. Swingline Loan is a U.S. Base Rate Loan, at a per annum rate (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be) equal to the U.S. Base Rate plus the Applicable Rate; and

(B) Quoted Rate U.S. Swingline Loans. If such U.S. Swingline Loan is a Quoted Rate U.S. Swingline Loan, at a per annum rate (computed on the basis of the actual number of days elapsed over a year of 360 days) equal to the Quoted Rate applicable thereto.

Notwithstanding any other provision to the contrary set forth in this Credit Agreement, in the event that the principal amount of any Quoted Rate U.S. Swingline Loan is not repaid on the last day of the Interest Period for such Loan, then such Loan shall be automatically converted into a U.S. Base Rate Loan at the end of such Interest Period.

(ii) Payment of Interest. Airgas promises to pay interest on U.S. Swingline Loans in arrears on each applicable Interest Payment Date (or at such other times as may be specified herein).

ARTICLE III

FOREIGN CURRENCY LOANS

3.1 Foreign Currency Loans.

(a) Foreign Currency Commitment. Subject to the terms and conditions hereof and in reliance upon the representations and warranties set forth herein, each Foreign Currency Lender severally agrees to make available to Airgas and the Foreign Borrowers such Foreign Currency Lender’s Applicable Percentage of revolving credit loans requested by Airgas or the applicable Foreign Borrower in U.S. Dollars or one or more Foreign Currencies (“Foreign Currency Loans”) from time to time from the Closing Date until the Maturity Date, or such earlier date as the Foreign Currency Commitments shall have been terminated as provided herein; provided, however, that the U.S. Dollar Equivalent of the aggregate principal amount of outstanding Foreign Currency Loans shall not exceed ONE HUNDRED MILLION U.S. DOLLARS ($100,000,000) (as such aggregate maximum amount may be increased or reduced from time to time as provided in Section 4.4, the “Foreign Currency Committed Amount”); provided, further, (i) with regard to each Foreign Currency Lender individually, the U.S. Dollar Equivalent of such Foreign Currency Lender’s outstanding Foreign Currency Loans shall not exceed such Foreign Currency Lender’s Applicable Percentage of the Foreign Currency Committed Amount and (ii) with regard to the Foreign Currency Lenders collectively, the U.S. Dollar Equivalent of the aggregate principal amount of outstanding Foreign Currency Loans plus the Foreign Swingline Facility Reserve shall not exceed the Foreign Currency Committed Amount. Foreign Currency Loans denominated in Foreign Currencies shall consist of Eurocurrency Loans. Foreign Currency Loans denominated in U.S. Dollars may consist of (A) in the case of borrowings by Airgas, U.S. Base Rate Loans, Eurocurrency Loans or a combination thereof, as Airgas may request, and (B) in the

case of any Foreign Borrower, Eurocurrency Loans only. Foreign Currency Loans may be repaid and reborrowed in accordance with the provisions hereof; provided, however, that no more than eleven (11) Eurocurrency Loans which are Foreign Currency Loans (combined) shall be outstanding hereunder at any time. For purposes hereof, Eurocurrency Loans with different Interest Periods shall be considered as separate Loans, even if they begin on the same date, although borrowings, extensions and conversions may, in accordance with the provisions hereof, be combined at the end of existing Interest Periods to constitute a new Eurocurrency Loan with a single Interest Period.

(b) Foreign Currency Loan Borrowings.

(i) Notice of Borrowing. Airgas and each Foreign Borrower (through a Responsible Officer) shall request a Foreign Currency Loan borrowing by written notice (or, in the case of borrowings by Airgas denominated in U.S. Dollars, telephone notice promptly confirmed in writing) to the Agent not later than 11:00 A.M. (1) three Business Days prior to the requested date of any borrowing of Eurocurrency Loans denominated in U.S. Dollars, (2) three Business Days (or four Business Days in the case of a Special Notice Currency) prior to the requested date of any borrowing of Eurocurrency Loans denominated in Foreign Currencies, and (3) on the requested date of any borrowing of U.S. Base Rate Loans. Each such request for borrowing shall be irrevocable and shall specify (A) that a Foreign Currency Loan is requested, (B) the date of the requested borrowing (which shall be a Business Day), (C) the aggregate principal amount to be borrowed, (D) the currency of such borrowing, (E) in the case of a Foreign Currency Loan to be denominated in U.S. Dollars, whether the borrowing shall be comprised of U.S. Base Rate Loans, Eurocurrency Loans or a combination thereof and (F) if applicable, the Interest Period(s) therefor. If Airgas or the applicable Foreign Borrower shall fail to specify in any such Notice of Borrowing (I) an applicable Interest Period, then such notice shall be deemed to be a request for an Interest Period of one month, (II) the currency of Foreign Currency Loan requested, then such notice shall be rejected until a currency is specified or (III) in the case of a Foreign Currency Loan denominated in U.S. Dollars, the type of Foreign Currency Loan requested, then (A) with respect to any borrowing by Airgas, such notice shall be deemed to be a request for a U.S. Base Rate Loan hereunder and (B) with respect to any borrowing by any Foreign Borrower, such notice shall be deemed to be a request for a Eurocurrency Loan with an Interest Period of one month. The Agent shall give notice to each Foreign Currency Lender promptly upon receipt of each Notice of Borrowing pursuant to this Section 3.1(b)(i), specifying the contents thereof and each such Foreign Currency Lender’s share of any borrowing to be made pursuant thereto.

(ii) Minimum Amounts. Each Foreign Currency Loan shall be in a minimum aggregate principal amount not less than the Borrowing Minimum and integral multiples of the Borrowing Multiple in excess thereof (or the remaining amount of the Foreign Currency Committed Amount, if less).

(iii) Advances. Each Foreign Currency Lender will make its Applicable Percentage of each Foreign Currency Loan borrowing available to the Agent for the account of Airgas or the applicable Foreign Borrower in Same Day Funds at the Agent’s office for the applicable currency not later than (x) 1:00 p.m., in the case of any Foreign Currency Loan denominated in U.S. Dollars, and (y) the Applicable Time specified by the Agent in the case of any Foreign Currency Loan in a Foreign Currency, in each case on the Business Day specified in the applicable Notice of Borrowing. Such borrowing will then be made available to Airgas or the applicable Foreign Borrower by the Agent in like funds as received by the Agent by (A) crediting the account of Airgas or such Foreign Borrower on the books of the Agent with the amount of such funds or (B) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Agent by Airgas or such Foreign Borrower, as the case may be. Each Foreign Currency Lender, at its option, may make any Foreign Currency Loan by causing any domestic or

foreign branch or Affiliate of such Lender to make such Loan, provided that any exercise of such option shall not affect the obligation of the applicable Borrower to repay such Loan in accordance with the terms of this Credit Agreement.

(c) Repayment. Airgas and each Foreign Borrower promises to pay the principal amount of all Foreign Currency Loans owing by Airgas or such Foreign Borrower, as the case may be, in full on the Maturity Date. The Obligations of each Foreign Borrower shall be several in nature, although Airgas shall guarantee the Foreign Obligations as provided in Article XII.

(d) Interest. Subject to the provisions of Section 4.1:

(i) U.S. Base Rate Loans. During such periods as Foreign Currency Loans shall be comprised in whole or in part of U.S. Base Rate Loans, such U.S. Base Rate Loans shall bear interest at a per annum rate equal to the U.S. Base Rate plus the Applicable Rate; and

(ii) Eurocurrency Loans. During such periods as Foreign Currency Loans shall be comprised in whole or in part of Eurocurrency Loans, such Eurocurrency Loans shall bear interest at a per annum rate equal to the Eurocurrency Rate plus the Applicable Rate plus (in the case of a Eurocurrency Loan of any Foreign Currency Lender which is lent from a lending office in the United Kingdom or a Participating Member State) the Mandatory Cost (it being understood that the interest calculated pursuant to this clause (ii) with respect to any Foreign Currency Lender shall be increased by the Mandatory Cost only to the extent that such Foreign Currency Lender is required to pay such Mandatory Cost).

Airgas and each Foreign Borrower promises to pay interest on the Foreign Currency Loans owing by such Person in arrears on each applicable Interest Payment Date (or at such other times as may be specified herein).

3.2 Foreign Borrowers.

(a) Effective as of the Closing Date, each of (i) Red-D-Arc Limited, (ii) Airgas Canada, Inc., (iii) Red-D-Arc (UK) Limited and (iv) Red-D-Arc (Netherlands) B.V. shall be a “Foreign Borrower” hereunder and may receive Foreign Currency Loans for its account on the terms and conditions set forth in this Credit Agreement.

(b) Airgas may at any time, upon not less than ten (10) Business Days’ notice from Airgas to the Agent (or, if requested by Airgas, such shorter period as may be agreed by the Agent in its sole discretion), request that any additional wholly-owned Foreign Subsidiary of Airgas (an “Applicant Foreign Borrower”) be designated as a Foreign Borrower to receive Foreign Currency Loans hereunder by delivering to the Agent (which shall promptly deliver counterparts thereof to each Foreign Currency Lender) a duly executed notice in substantially the form of Exhibit 3.2(a) (a “Foreign Borrower Request”). If the Agent and the Foreign Currency Lenders agree that an Applicant Foreign Borrower shall be entitled to receive Foreign Currency Loans hereunder, then the Agent and the Foreign Currency Lenders shall send an agreement in substantially the form of Exhibit 3.2(b) (a “Foreign Borrower Joinder Agreement”) to Airgas specifying (i) the additional terms and conditions applicable to extensions of credit to such Applicant Foreign Borrower and (ii) the effective date upon which the Applicant Foreign Borrower shall constitute a Foreign Borrower for purposes hereof, whereupon the execution thereof by Airgas and such Applicant Foreign Borrower, such Foreign Borrower shall be permitted to receive Foreign Currency Loans hereunder, on the terms and conditions set forth herein and therein, and such Foreign Borrower otherwise shall be a Borrower for all purposes of this Agreement. The parties hereto acknowledge and agree that prior to any Applicant Foreign Borrower becoming entitled to utilize the credit facilities provided for in this Article III the Agent and the Foreign Currency Lenders shall have received such supporting resolutions, incumbency certificates, opinions of

counsel and other documents or information, in form, content and scope reasonably satisfactory to the Agent, as may be required by the Agent or the Foreign Currency Lenders in their reasonable discretion. Notwithstanding the forgoing, to the extent that Airgas submits a Foreign Borrower Request with respect to an Applicant Foreign Borrower that is incorporated or otherwise organized under the laws of The Netherlands, Canada or the United Kingdom, such Applicant Foreign Borrower may become a Foreign Borrower upon the execution and delivery of a Foreign Borrower Joinder Agreement (which must only be signed by the Agent and which shall not contain any additional terms and conditions applicable to such Applicant Foreign Borrower); provided that the Agent shall have received such supporting resolutions, incumbency certificates, opinions of counsel and other documents or information, in form, content and scope reasonably satisfactory to the Agent.

(d) Each Foreign Subsidiary of Airgas that is or becomes a “Foreign Borrower” pursuant to this Section 3.2 which is a UK Borrower shall, upon becoming a Foreign Borrower, make any filings (and provide copies of such filings) as required by, and in accordance with, Section 4.10(g).

(e) Each Foreign Subsidiary of Airgas that is or becomes a “Foreign Borrower” pursuant to this Section 3.2 hereby irrevocably appoints Airgas as its agent for all purposes relevant to this Credit Agreement and each of the other Credit Documents, including (i) the giving and receipt of notices, and (ii) the execution and delivery of all documents, instruments and certificates contemplated herein and all modifications hereto. Any acknowledgment, consent, direction, certification or other action which might otherwise be valid or effective only if given or taken by all Foreign Borrowers, or by each Foreign Borrower acting singly, shall be valid and effective if given or taken only by Airgas, whether or not any such other Foreign Borrower joins therein. Any notice, demand, consent, acknowledgement, direction, certification or other communication delivered to Airgas in accordance with the terms of this Credit Agreement shall be deemed to have been delivered to each Foreign Borrower.

(f) Airgas may from time to time, upon not less than five (5) Business Days’ written notice from Airgas to the Agent (or such shorter period as may be agreed by the Agent in its sole discretion), terminate a Foreign Borrower’s status as such, provided that there are no outstanding Foreign Currency Loans payable by such Foreign Borrower, or other amounts payable by such Foreign Borrower on account of any Foreign Currency Loans made to it, as of the effective date of such termination. The Agent will promptly notify the Foreign Currency Lenders of any such termination of a Foreign Borrower’s status.

3.3 Foreign Swingline Loan Subfacilities.

(a) Establishment of Foreign Swingline Facilities. Airgas may at any time and from time to time establish one or more additional swingline facilities (each a “Foreign Swingline Facility”) with a Foreign Currency Lender (or a branch or affiliate of a Foreign Currency Lender) by delivering, with the consent of such Foreign Currency Lender (or such branch of affiliate) to the Agent a notice in substantially the form of Exhibit 3.3 (each such notice a “Foreign Swingline Facility Notice”), provided that immediately after giving effect to such Foreign Swingline Facility, the aggregate amount of all Foreign Swingline Sublimits shall not exceed the Foreign Currency Committed Amount. Each Foreign Swingline Facility Notice shall set forth (i) the name and contact information (including address, telecopier number, electronic mail address and telephone number) of the Foreign Currency Lender (or a branch or affiliate of a Foreign Currency Lender) that will act as the swingline lender for such additional swingline facility (the “Foreign Swingline Lender”), (ii) the name(s) of the Foreign Subsidiary(ies) of Airgas that will be permitted to borrow thereunder (each such Foreign Subsidiary, a “Foreign Swingline Borrower”), (iii) the applicable currency(ies) available for borrowing thereunder and (iv) the maximum principal amount (expressed in U.S. Dollars) of borrowings that may at any time be outstanding thereunder (the “Foreign Swingline Sublimit”). Each Foreign Swingline Facility Notice shall be executed by Airgas, the Foreign Swingline Lender and the Foreign Swingline

Borrower(s) that will be permitted to borrow thereunder. On the date five (5) Business Days (or such shorter period as may be agreed to by the Agent) after receipt by the Agent of the Foreign Swingline Facility Notice, such Foreign Swingline Facility shall become effective for purposes of this Credit Agreement and the other Credit Documents and all borrowings thereunder on and after such date shall be deemed Foreign Swingline Loans. Notwithstanding the foregoing, to the extent the outstanding principal amount of Foreign Swingline Loans under any Foreign Swingline Facility exceeds such Foreign Swingline Sublimit (other than a result solely of foreign currency fluctuations), such excess (and any accrued interest or fees on such excess) shall not constitute “Obligations” for purposes of the Credit Documents.

(b) Foreign Swingline Loans. Subject to the terms and conditions set forth herein and in reliance upon the agreements of the other Foreign Currency Lenders set forth in this Section 3.3, each Foreign Swingline Lender shall make revolving credit loans requested by to the applicable Foreign Swingline Borrower(s) and in the currency(ies) set forth in the applicable Foreign Swingline Facility Notice (each a “Foreign Swingline Loan” and, collectively, the “Foreign Swingline Loans”) from time to time from the effective date of the applicable Foreign Swingline Facility until the Maturity Date in an aggregate amount not to exceed at any time outstanding the amount of the applicable Foreign Swingline Sublimit, notwithstanding the fact that such Foreign Swingline Loans, when aggregated with the Applicable Percentage of the outstanding principal amount of Foreign Currency Loans of the Foreign Currency Lender acting as such Foreign Swingline Lender, may exceed the amount of such Foreign Currency Lender’s Foreign Currency Commitment, unless (x) any Foreign Currency Lender at such time is a Defaulting Lender and (y) such Foreign Swingline Lender has not entered into arrangements reasonably satisfactory to it with Airgas or such Defaulting Lender to eliminate such Foreign Swingline Lender’s Fronting Exposure with respect to such Defaulting Lender (including by operation of Section 4.16(a)(iv)), in which case each Foreign Swingline Lender may in its discretion, make such Foreign Swingline Loans; provided, however, (i) the aggregate principal amount of Foreign Swingline Loans outstanding at any time shall not exceed the Foreign Swingline Sublimit for the applicable Foreign Swingline Facility, and (ii) the aggregate principal amount of all outstanding Foreign Currency Loans plus the Foreign Swingline Facility Reserve shall not exceed the Foreign Currency Committed Amount. Foreign Swingline Loans may be repaid and reborrowed in accordance with the provisions hereof.

(i) The borrowing procedures for each Foreign Swingline Facility shall be as agreed to by the applicable Foreign Swingline Borrower(s) and the applicable Foreign Swingline Lender.

(ii) The applicable Foreign Swingline Lender shall not make any Foreign Swingline Loan if it has received notice (by telephone or in writing) from the Agent (including at the request of any Lender) prior to the date of any proposed borrowing of Foreign Swingline Loans (A) directing such Foreign Swingline Lender not to make such Foreign Swingline Loan as a result of the limitations set forth in the proviso to the first sentence of Section 3.3(b), or (B) that one or more of the applicable conditions specified in Article V is not then satisfied.

(d) Repayment of Foreign Swingline Loans. The applicable Foreign Swingline Borrower(s) promise to pay the principal amount of all Foreign Swingline Loans on the earlier of (A) the maturity date agreed to by the applicable Foreign Swingline Lender and the applicable Foreign Swingline Borrower(s) or (B) the Maturity Date. Each Foreign Currency Lender hereby agrees that, upon written notice from a Foreign Swingline Lender, it shall forthwith purchase from such Foreign Swingline Lender (or, if such purchase from the Foreign Swingline Lender is prohibited by applicable law, from an Affiliate or other branch office of such Foreign Swingline Lender) such participations in such Foreign Swingline Lender’s outstanding Foreign Swingline Loans as shall be necessary to cause each Foreign Currency Lender to share in such Foreign Swingline Loans ratably based upon its Applicable Percentage of the Foreign Currency Committed Amount (such participations to be denominated in U.S. Dollars at the U.S Dollar Equivalent amount), provided that

(A) all interest payable on such Foreign Swingline Loans shall be for the account of the Foreign Swingline Lender until the date as of which the respective participation is purchased and (B) at the time any purchase of participations pursuant to this sentence is actually made, the purchasing Foreign Currency Lender shall be required to pay to the applicable Foreign Swingline Lender interest on the principal amount of participation purchased for each day from and including the day upon which such written notice was delivered to but excluding the date of payment for such participation, at the rate equal to the Overnight Rate. In connection with any such purchase of participation interests in Foreign Swingline Loans pursuant to this subsection (d), the applicable Foreign Swingline Borrower and Airgas each agree (A) if the interest received by a participating Lender on account thereof is less than the interest such Lender would have received had the interest rate per annum applicable to such participations equaled an interest rate per annum equal to the sum of rate specified in clause (c) of the definition of U.S. Base Rate plus the Applicable Rate for U.S. Base Rate Loans, to pay such Lender additional amounts equal to the difference and (B) to reimburse each participant in respect of any taxes applicable to such participation in the manner, and subject to the limitations, prescribed in Section 4.10.

(e) Interest on Foreign Swingline Loans. Subject to the provisions of Section 4.1, each Foreign Swingline Loan shall bear interest at a rate per annum agreed to by the applicable Foreign Swingline Borrower(s) and the applicable Foreign Swingline Lender. Each applicable Foreign Swingline Borrower promises to pay interest on its Foreign Swingline Loans in arrears on each applicable Interest Payment Date (or at such other times as may be specified herein). Each Foreign Swingline Lender shall be responsible for invoicing the applicable Foreign Swingline Borrower(s) for interest on the Foreign Swingline Loans made by such Foreign Swingline Lender. Until each Foreign Currency Lender funds its risk participation pursuant to this Section 3.3 to refinance such Lender’s Applicable Percentage of any Foreign Swingline Loan, interest in respect of such Applicable Percentage shall be solely for the account of the Foreign Swingline Lender that made such Foreign Swingline Loan. Interest payable on outstanding Foreign Swingline Loans (including risk participations therein) is subject to adjustment as provided in Section 4.5(a)(ii).

(f) Payments Directly to Foreign Swingline Lender. The applicable Foreign Swingline Borrower(s) shall make all payments of principal and interest in respect of Foreign Swingline Loans directly to the applicable Foreign Swingline Lender.

(b) Non-Payment Defaults. Except as provided in Section 4.1(a), during the continuance of any Event of Default for a period of more than 30 days from the date Airgas receives notice thereof from the Agent, the principal of and, to the extent permitted by law, interest on the Loans and any other amounts owing hereunder or under the other Credit Documents shall, at the discretion of the Required Lenders, bear interest, payable on demand, at the Default Rate.

4.2 Extension and Conversion.

(a) U.S. Revolving Loans. Airgas shall have the option, on any Business Day, to extend existing U.S. Revolving Loans into a subsequent permissible Interest Period or to convert any such U.S. Revolving Loans into U.S. Revolving Loans of another interest rate type; provided, however, that (i) except as provided in Section 4.8, Eurocurrency Loans may be converted into U.S. Base Rate Loans only on the last day of the Interest Period applicable thereto, (ii) Loans extended as, or converted into, Eurocurrency Loans shall be subject to the terms of the definition of “Interest Period” set forth in Section 1.1 and shall be in such minimum amounts as provided in Section 2.1(b)(ii), (iii) no more than eleven (11) Eurocurrency Loans which are U.S. Revolving Loans shall be outstanding hereunder at any time (it being understood that, for purposes hereof, Eurocurrency Loans with different Interest Periods shall be considered as separate Eurocurrency Loans, even if they begin on the same date, although borrowings, extensions and conversions may, in accordance with the provisions hereof, be combined at the end of existing Interest Periods to constitute a new Eurocurrency Loan with a single Interest Period), (iv) any request for extension or conversion of a Eurocurrency Loan which shall fail to specify an Interest Period shall be deemed to be a request for an Interest Period of one month and (v) U.S. Swingline Loans may not be extended or converted pursuant to this Section 4.2. Each such extension or conversion shall be effected by Airgas by giving a Notice of Extension/Conversion (or telephone notice promptly confirmed in writing) to the Agent prior to 11:00 A.M. on the Business Day of, in the case of the conversion of a Eurocurrency Loan into a U.S. Base Rate Loan, and on the third Business Day prior to, in the case of the extension of a Eurocurrency Loan as, or conversion of a U.S. Base Rate Loan into, a Eurocurrency Loan, the date of the proposed extension or conversion, specifying the date of the proposed extension or conversion, the Loans to be so extended or converted, the types of Loans into which such Loans are to be converted and, if appropriate, the applicable Interest Periods with respect thereto. In the event Airgas fails to request extension or conversion of any Eurocurrency Loan in accordance with this Section, or any such conversion or extension is not permitted or required by this Section, then such Eurocurrency Loan shall be automatically converted into a U.S. Base Rate Loan at the end of the Interest Period applicable thereto. The Agent shall give each affected Lender notice as promptly as practicable of any such proposed extension or conversion affecting any U.S. Revolving Loan.

(b) Foreign Currency Loans. Airgas or the applicable Foreign Borrower shall have the option, on any Business Day, to extend existing Foreign Currency Loans into a subsequent permissible Interest Period or to convert any such Loans into Foreign Currency Loans of another interest rate type (subject to the limitations set forth in Section 3.1(a)); provided, however, that (i) except as provided in Section 4.8, Eurocurrency Loans may be converted into U.S. Base Rate Loans only on the last day of the Interest Period applicable thereto, (ii) Loans extended as, or converted into, Eurocurrency Loans shall be subject to the terms of the definition of “Interest Period” set forth in Section 1.1 and shall be in such minimum amounts as provided in Section 3.1(b)(ii), (iii) no more than eleven (11) Eurocurrency Loans which are Foreign Currency Loans (combined) shall be outstanding hereunder at any time (it being understood that, for purposes hereof, Loans with different Interest Periods shall be considered as separate Loans, even if they begin on the same date, although borrowings, extensions and conversions may, in accordance with the provisions hereof, be combined at the end of existing Interest Periods to constitute a new Eurocurrency Loan with a single Interest Period) and (iv) Foreign Swingline Loans may not be extended or converted pursuant to this Section 4.2. Each such extension or conversion shall be effected by Airgas or the applicable Foreign Borrower by giving a Notice of Extension/Conversion (or, in the case of Loans of Airgas that are denominated in U.S. Dollars, telephone notice promptly confirmed in writing) to the Agent prior to 11:00 A.M. (i) on the Business Day of, in the case of the conversion of a Eurocurrency Loan denominated in U.S. Dollars into a U.S. Base Rate Loan, (ii) three Business Days prior to the requested date of any extension or conversion of, Eurocurrency Loans denominated in U.S. Dollars or of any conversion of Eurocurrency Loans denominated in U.S. Dollars to U.S. Base Rate Loans and (iii) three Business Days (or four Business Days in the case of a Special Notice Currency) prior to the requested date of any extension or conversion of Eurocurrency Loans denominated in Foreign Currencies. Each such request for extension or conversion shall specify (1) the date of the proposed extension or conversion, (2) the Loans to be so extended or converted, (3) the types of Loans into which such Loans are to be converted and, (4) if appropriate, the applicable Interest Periods and

currency with respect thereto. If Airgas or the applicable Foreign Borrower fails to specify an Interest Period or the type of a Foreign Currency Loan in a request for extension or conversion or if Airgas or the applicable Foreign Borrower fails to give a timely notice requesting an extension or conversion, then the applicable Foreign Currency Loans shall be extended as, or converted to, a Eurocurrency Loan denominated in the same currency an Interest Period of one month. The Agent shall give each affected Lender notice as promptly as practicable of any such proposed extension or conversion affecting any Foreign Currency Loan. No Foreign Currency Loan may be converted into or continued as a Foreign Currency Loan denominated in a different currency, but instead must be prepaid in the original currency of such Loan and reborrowed in the other currency.

4.3 Prepayments.

(a) Voluntary Prepayments. U.S. Revolving Loans, U.S. Swingline Loans and Foreign Currency Loans may be prepaid in whole or in part from time to time, subject to Section 4.11, but otherwise without premium or penalty; provided, however, that (i) Eurocurrency Loans may only be prepaid on three Business Days’ prior written notice to the Agent, and specifying the applicable Loans to be prepaid; (ii) any prepayment of Eurocurrency Loans or Quoted Rate U.S. Swingline Loans will be subject to Section 4.11; and (iii) each such partial prepayment of Loans shall be (A) in the case of U.S. Revolving Loans, in a minimum principal amount of $5,000,000 and integral multiples of $1,000,000 in excess thereof, (B) in the case of U.S. Swingline Loans, in a minimum principal amount of $100,000 and integral multiples thereof, and (C) in the case of Foreign Currency Loans, in a minimum principal amount not less than the Borrowing Minimum and integral multiples of the Borrowing Multiple in excess thereof. The applicable Foreign Swingline Borrower may prepay Foreign Swingline Loans in accordance with terms agreed to by such Foreign Swingline Borrower and the applicable Foreign Swingline Lender, and any prepayment of a Foreign Swingline Loan shall be subject to Section 4.11. Subject to the foregoing terms, amounts prepaid under this Section 4.3(a) shall be applied as the applicable Borrower may elect. Subject to Section 4.16, each such prepayment shall be applied to the Loans of the Lenders in accordance with their respective Applicable Percentages.

(b) Mandatory Prepayments.

(i) U.S. Revolving Committed Amount. If at any time the sum of the aggregate principal amount of outstanding U.S. Revolving Loans plus the aggregate principal amount of outstanding U.S. Swingline Loans plus U.S. LOC Obligations outstanding shall exceed the U.S. Revolving Committed Amount, Airgas shall prepay immediately the outstanding principal balance on the U.S. Revolving Loans and/or U.S. Swingline Loans (and after all U.S. Revolving Loans and U.S. Swingline Loans have been repaid, pay to the Agent additional cash in respect of U.S. LOC Obligations, to be held by the Agent, for the benefit of the U.S. Issuing Lenders and the U.S. Revolving Lenders, in a cash collateral account) in an amount sufficient to eliminate such excess.

(ii) Foreign Currency Committed Amount. If at any time the Agent notifies Airgas that the U.S. Dollar Equivalent of the sum of (A) the aggregate principal amount of outstanding Foreign Currency Loans plus (B) the Foreign Swingline Facility Reserve shall exceed (x) 105% of the Foreign Currency Committed Amount (solely as a result of currency fluctuations) or (y) the Foreign Currency Committed Amount (other than as a result of currency fluctuations), Airgas and the applicable Borrowers shall prepay immediately (or, in the case of any such excess resulting solely from currency fluctuations, not later than five (5) Business Days after receipt by Airgas of such notice) the outstanding principal balance on the Foreign Currency Loans and/or permanently reduce Foreign Swingline Facilities (together with any accompanying prepayments) in an amount sufficient to eliminate such excess.

Within the parameters of the applications set forth above, prepayments of U.S. Revolving Loans shall be applied first to U.S. Base Rate Loans and then to Eurocurrency Loans in direct order of Interest Period maturities. All prepayments under this Section 4.3(b) shall be subject to Section 4.11 and be accompanied by interest on the principal amount prepaid through the date of prepayment.

4.4 Termination and Reduction of Commitments; Increase of Commitments.

(a) Voluntary Reductions; Terminations.

(A) Airgas may from time to time permanently reduce or terminate the U.S. Revolving Committed Amount in whole or in part (in minimum aggregate amounts of $5,000,000 or in integral multiples of $1,000,000 in excess thereof (or, if less, the full remaining amount of the U.S. Revolving Committed Amount)) upon five Business Days’ prior written notice to the Agent; provided, however, no such termination or reduction shall be made which would cause the aggregate principal amount of outstanding U.S. Revolving Loans plus the aggregate principal amount of outstanding U.S. Swingline Loans plus U.S. LOC Obligations outstanding to exceed the U.S. Revolving Committed Amount unless, concurrently with such termination or reduction, the respective Obligations are repaid to the extent necessary to eliminate such excess. The U.S. Revolving Commitments shall automatically terminate on the Maturity Date;

(B) Airgas may from time to time permanently reduce or terminate the Foreign Currency Committed Amount in whole or in part (in minimum aggregate amounts of $5,000,000 or in integral multiples of $1,000,000 in excess thereof (or, if less, the full remaining amount of the Foreign Currency Committed Amount)) upon five Business Days’ prior written notice to the Agent; provided, however, no such termination or reduction shall be made which would cause the U.S. Dollar Equivalent of the aggregate principal amount of outstanding Foreign Currency Loans plus the Foreign Swingline Facility Reserve to exceed the Foreign Currency Committed Amount unless, concurrently with such termination or reduction, the respective Obligations are repaid (and/or the Foreign Swingline Facilities are reduced) to the extent necessary to eliminate such excess. The Foreign Currency Commitments shall automatically terminate on the Maturity Date.

(C) Airgas may, at its option, elect to increase or decrease any Foreign Swingline Sublimit; provided that (i) Airgas shall give three (3) Business Days prior written notice to the Agent and the applicable Foreign Swingline Lender of such election; and (ii) after giving effect thereto, the U.S. Dollar Equivalent of the aggregate amount of all Foreign Swingline Sublimits shall not exceed the difference between the Foreign Currency Committed Amount minus the U.S. Dollar Equivalent of the aggregate principal amount of all outstanding Foreign Currency Loans.

The Agent shall promptly notify each affected Lender of receipt by the Agent of any notice pursuant to this Section 4.4(a).

The applicable Borrowers shall pay to the Agent for the account of the applicable Lenders in accordance with the terms of Section 4.5(a), on the date of each termination or reduction of the U.S. Revolving Committed Amount or the Foreign Currency Committed Amount, the U.S. Revolving Commitment Unused Fee or the Foreign Currency Commitment Unused Fee, as applicable, accrued through the date of such termination or reduction on the amount of the U.S. Revolving Committed Amount or the Foreign Currency Committed Amount so terminated or reduced.

(b) Increase in Commitments. Following the Closing Date, Airgas shall have the right, upon at least fifteen (15) Business Days’ prior written notice to the Agent, to increase the U.S. Revolving Committed Amount and/or the Foreign Currency Committed Amount by an aggregate amount for all such increases not to exceed $325,000,000, in one or more increases, at any time and from time to time; subject, however, in any such case, to satisfaction of the following conditions precedent:

(iv) since March 31, 2010, there has been no development or event relating to or affecting the Consolidated Parties which has had or would be reasonably expected to have a Material Adverse Effect;

(v) such increase shall be an integral multiple of $1,000,000 and shall in no event be less than $5,000,000;

(vi) such requested increase shall be effective on such date only to the extent that, on or before such date, (A) the Agent shall have received and accepted a corresponding amount of Additional Commitment(s) pursuant to a commitment letter(s) acceptable to the Agent from one or more lenders that would qualify as an Eligible Assignee (assuming such transaction were treated as an assignment pursuant to Section 11.3(b)) (it being understood that no Lender shall be obligated to increase any of its Commitments pursuant to this Section without its consent) and (B) each such lender shall have executed an agreement in the form of Exhibit 4.4 hereto (each such agreement a “New Commitment Agreement”), accepted in writing therein by the Agent and, with respect to any lender that is not at such time a Lender hereunder, Airgas, with respect to the Additional Commitment of such lender;

(vii) the Agent shall have received all documents (including board of directors’ resolutions and opinions of counsel) it may reasonably request relating to the corporate or other necessary authority for and the validity of such increase in the U.S. Revolving Committed Amount and/or the Foreign Currency Committed Amount, and any other matters relevant thereto, all in form and substance reasonably satisfactory to the Agent;

(viii) if the reallocation, if any, of outstanding Loans among the Lenders in connection with such increase results in the prepayment of Eurocurrency Loans on a day which is not the last day of an Interest Period with respect thereto, Airgas shall have paid to each affected Lender such amounts, if any, as may be required pursuant to Section 4.11; and

(ix) the aggregate amount of all increases to the Foreign Currency Committed Amount effected by this Section 4.4(b) shall not exceed $50,000,000.

(c) Upon the effectiveness of the increase in the U.S. Revolving Committed Amount and/or the Foreign Currency Committed Amount, as applicable, pursuant to subsection (b), (A) the Applicable Percentage of each Lender shall be automatically adjusted to give effect to such increase, provided that the amount of each Lender’s U.S. Revolving Commitment and/or Foreign Currency Commitment, as applicable, (other than a Lender whose U.S. Revolving Commitment and/or Foreign Currency Commitment, as applicable, shall have been increased in connection with such increase) shall remain unchanged and (B) Airgas, the Agent and the Lenders will use all commercially reasonable efforts to assign and assume outstanding Loans of the affected category to conform the respective amounts thereof held by each Lender to the Applicable Percentage as so adjusted, it being understood that the parties hereto shall use commercially reasonable efforts to avoid prepayment or assignment of any affected Loan that is a Eurocurrency Loan on a day other than the last day of the Interest Period applicable thereto.

4.5 Fees.

(a) Unused Fees.

(i) U.S. Revolving Commitment Unused Fee. In consideration of the U.S. Revolving Commitments of the U.S. Revolving Lenders hereunder, Airgas agrees to pay to the Agent for the account of the U.S. Revolving Lenders a fee (the “U.S. Revolving Commitment Unused Fee”) on the actual daily amount by which (a) the U.S. Revolving Committed Amount exceeds (b) the sum of (i) the outstanding aggregate principal amount of all U.S. Revolving Loans plus (ii) the outstanding aggregate principal amount of all U.S. LOC Obligations, computed at a per annum rate for each day during the applicable period at a rate equal to the Applicable Rate in effect from time to time.

In addition to the fees payable pursuant to clauses (i) and (ii) above, Airgas promises to pay to the applicable U.S. Issuing Lender for its own account without sharing by the other Lenders (A) an issuance fee in an amount agreed between Airgas and such U.S. Issuing Lender on the face amount of each trade U.S. Letter of Credit, payable on each date of issuance or extension of a trade U.S. Letter of Credit, (B) a drawing fee in an amount agreed between Airgas and such U.S. Issuing Lender on the amount of each drawing on any trade U.S. Letter of Credit, payable on each date of drawing under a trade U.S. Letter of Credit, (C) the letter of credit fronting and negotiation fees agreed to by Airgas and such U.S. Issuing Lender and (D) the customary charges from time to time of such U.S. Issuing Lender agreed to by Airgas with respect to the issuance, amendment, transfer, administration, cancellation and conversion of, and drawings under, such U.S. Letters of Credit.

4.6 Capital Adequacy.

If any Lender has determined, after the Closing Date, that the adoption of, or any change in, or any change by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration of, any applicable law, rule or regulation regarding capital adequacy, or compliance by such

Lender with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s policies with respect to capital adequacy), then, upon notice from such Lender to the applicable Borrowers, the Borrowers shall be obligated to pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Upon making a request for such additional amount hereunder, such Lender will furnish to the Borrowers a statement certifying the amount of such reduction and describing the event giving rise to such reduction. Each determination by any such Lender of amounts owing under this Section shall, absent manifest error, be conclusive and binding on the parties hereto.

4.7 Inability To Determine Interest Rate.

If prior to the first day of any Interest Period, the Agent shall have determined (which determination shall be conclusive and binding upon the Borrowers) that, by reason of circumstances affecting the relevant market, (i) adequate and reasonable means do not exist for ascertaining the Eurocurrency Rate for such Interest Period or (ii) deposits (whether in U.S. Dollars or a Foreign Currency) are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurocurrency Loan, the Agent shall give written notice thereof to Airgas and the affected Lenders as soon as practicable thereafter. If such notice is given, the applicable Borrower may revoke any pending request for a borrowing of, conversion to or extension of Eurocurrency Loans in the affected currency or currencies or, failing that and until such time as such notice has been withdrawn by the Agent, (A) in the case of Eurocurrency Loans of Airgas that are denominated in U.S. Dollars, (x) any such Eurocurrency Loans requested to be made on the first day of such Interest Period shall be made as U.S. Base Rate Loans and (y) any Loans that were to have been converted on the first day of such Interest Period to or extended as Eurocurrency Loans shall be converted to or extended as U.S. Base Rate Loans and (B) in the case of (1) Eurocurrency Loans of a Foreign Borrower that are denominated in U.S. Dollars or (2) any Eurocurrency Loans that are denominated in a Foreign Currency, (x) any such Eurocurrency Loans requested to be made on the first day of such Interest Period shall be made (assuming that the circumstances described in clause (ii) immediately above have not occurred) bearing interest at such rate as the Agent and the applicable Borrower shall agree adequately reflects the cost to the Foreign Currency Lenders of making such Loans, (y) any Loans that were to have been extended as of the first day of such Interest Period shall be extended (assuming that the circumstances described in clause (ii) immediately above have not occurred) bearing interest at such rate as the Agent and the applicable Borrower shall agree adequately reflects the cost to the Foreign Currency Lenders of maintaining such Loans and (z) if the circumstances described in clause (ii) immediately above have occurred, then any request for a borrowing in such currency shall be ineffective and any outstanding Loans denominated in such currency shall be repaid in full at the end of the current Interest Period (or such earlier time, if any, as required by law).

4.8 Illegality.

Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof occurring after the Closing Date shall make it unlawful for any Lender (i) to make or maintain Loans whose interest is determined by reference to the Eurocurrency Rate or (ii) to determine or charge interest rates based upon the Eurocurrency Rate, in either case as contemplated by this Credit Agreement, (a) such Lender shall promptly give written notice of such circumstances to Airgas and the Agent (which notice shall be withdrawn whenever such circumstances no longer exist), (b) the commitment of such Lender hereunder to make Eurocurrency Loans, continue Eurocurrency Loans as such and convert a U.S. Base Rate Loan to Eurocurrency Loans shall forthwith be canceled and, until such time as it shall no longer be unlawful for such Lender to make or maintain Eurocurrency Loans, such Lender shall have no commitment to make Eurocurrency Loans, (c) if such notice

asserts the illegality of such Lender making or maintaining U.S. Base Rate Loans the interest rate on which is determined by reference to the Eurocurrency Rate component of the U.S. Base Rate, the interest rate on which U.S. Base Rate Loans of such Lender, shall, if necessary to avoid such illegality, be determined by the Agent without reference to the Eurocurrency Rate component of the U.S. Base Rate, and (d) such Lender’s Loans then outstanding as Eurocurrency Loans, if any, shall (1) in the case of outstanding Eurocurrency Loans of Airgas that are denominated in U.S. Dollars, be converted automatically to U.S. Base Rate Loans (the interest rate on which U.S. Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Agent without reference to the Eurocurrency Rate component of the U.S. Base Rate) on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law and (2) in the case of (x) outstanding Eurocurrency Loans of a Foreign Borrower that are denominated in U.S. Dollars or (y) outstanding Eurocurrency Loans that are denominated in a Foreign Currency, be converted automatically to Loans that bear interest at such rate as the Agent and the applicable Borrower shall agree adequately reflects the cost to the Foreign Currency Lenders of maintaining such Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurocurrency Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the applicable Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 4.11.

4.9 Requirements of Law.

If, after the Closing Date, the adoption of or any change in any Requirement of Law or in the interpretation or application thereof applicable to any Lender, or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority, in each case made subsequent to the Closing Date (or, if later, the date on which such Lender becomes a Lender):

(a) shall subject such Lender to any tax of any kind whatsoever with respect to any U.S. Letter of Credit, any Eurocurrency Loans or its obligation to make Eurocurrency Loans, or change the basis of taxation of payments to such Lender in respect thereof (except for (i) Non-Excluded Taxes covered by Section 4.10 (including Non-Excluded Taxes imposed solely by reason of any failure of such Lender to comply with its obligations under Section 4.10(b)) and (ii) changes in taxes measured by or imposed upon the overall net income, or franchise tax (imposed in lieu of such net income tax), of such Lender or its applicable lending office, branch, or any affiliate thereof));

(b) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender which is not otherwise included in the determination of the Eurocurrency Rate hereunder;

(c) result in the failure of the Mandatory Cost, as calculated hereunder, to represent the cost to any Lender of complying with the requirements of the Bank of England and/or the Financial Services Authority or the European Central Bank in relation to its making, funding or maintaining Eurocurrency Loans; or

(d) impose on any Lender or the London interbank market any other condition, cost or expense affecting this Credit Agreement or Eurocurrency Loans made by such Lender or any other extensions of credit hereunder or participation therein;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining any Eurocurrency Loan, or

issuing or participating in any U.S. Letter of Credit or to reduce any amount receivable hereunder in respect thereof, then, in any such case, upon notice to the Borrowers from such Lender, through the Agent, in accordance herewith, the Borrowers shall be obligated to promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable, provided that, in any such case, each applicable Borrower may elect to (x) in the case of Eurocurrency Loans of Airgas that are denominated in U.S. Dollars, convert such Eurocurrency Loans to U.S. Base Rate Loans and (y) in the case of (1) Eurocurrency Loans of a Foreign Borrower that are denominated in U.S. Dollars or (2) any Eurocurrency Loans that are denominated in a Foreign Currency, convert such Eurocurrency Loans to Loans that bear interest at such rate as the Agent and the applicable Borrower shall agree adequately reflects the cost to such Lender of maintaining such Loan, in each case by giving the Agent at least one Business Day’s notice of such election, in which case such applicable Borrowers shall promptly pay to such Lender, upon demand, without duplication, such amounts, if any, as may be required pursuant to Section 4.11; provided further, however, that if the result of any the foregoing shall be to decrease the cost to any Lender of making or maintaining any Eurocurrency Loan, or of issuing or participating in any U.S. Letter of Credit by a material amount, then such Lender will credit to the applicable Borrowers an amount equal to such decreased costs. If any Lender becomes entitled to claim any additional amounts pursuant to this subsection, it shall provide prompt notice thereof to Airgas, through the Agent, certifying (x) that one of the events described in this Section 4.9 has occurred and describing in reasonable detail the nature of such event, (y) as to the increased cost or reduced amount resulting from such event and (z) as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof. Such a certificate as to any additional amounts payable pursuant to this subsection submitted by such Lender, through the Agent, to the Borrowers shall be conclusive and binding on the parties hereto in the absence of manifest error. Each Lender agrees that it will promptly refund any amounts received by it pursuant to this Section 4.9 that were erroneously billed to the Borrowers, together with interest thereon at the U.S. Base Rate. This covenant shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

4.10 Taxes.

(a) Withholding Taxes.

(i) Payments Free of Withholding Taxes. Except as provided below in this subsection and subject to subsection (e) below, all payments made by the Borrowers (including, for purposes of this Section 4.10, Airgas in its capacity as guarantor pursuant to Article XII) under this Credit Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court, or governmental body, agency or other official, excluding:

(A) taxes measured by or imposed upon the overall net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch taxes, taxes on doing business or taxes on the overall capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof, in each case imposed in lieu of net income taxes, imposed: (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof; or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Credit Agreement;

(B) any withholding tax imposed under the laws of the United States on amounts payable by Airgas to any Lender that is not a U.S. Person pursuant to any Requirement of Law in force at the time such Lender becomes a party hereto (or designates a new lending office) except, in the case of an assignment (or designation of a new lending office), to the extent that such Lender’s assignor (or, in the case of a designation of a new lending office, such Lender) was entitled at the time of assignment (or designation of a new lending office) to receive additional amounts with respect to such withholding tax pursuant to this Section 4.10(a);

(C) any withholding tax that is required to be deducted by applicable law and is imposed on amounts paid by any Foreign Borrower identified by name in Section 3.2(a), by the jurisdiction in which such Foreign Borrower was organized, to any Foreign Currency Lender, pursuant to a Requirement of Law in force at the time such Lender becomes a party hereto (or designates a new lending office) except:

(1) to the extent that such withholding tax is attributable solely to a change after the Closing Date in circumstances relating to the Foreign Borrower as a result of an action that is within the control of Airgas, the Foreign Borrower or any of their Affiliates, including, but not limited to, a change in the jurisdiction in which the relevant Foreign Borrower is resident for tax purposes or from which payments hereunder are made, or

(2) in the case of an assignment (or designation of a new lending office), to the extent that such Lender’s assignor (or, in the case of a designation of a new lending office, such Lender) was entitled at the time of assignment (or designation of a new lending office) to receive additional amounts with respect to such withholding tax pursuant to this Section 4.10(a);

(D) any withholding tax that is required to be deducted by applicable law and is imposed on amounts paid by any new Foreign Borrower designated as such pursuant to Section 3.2(b) that is organized and resident for tax purposes at the time of designation solely in The Netherlands, Canada or the United Kingdom, by the jurisdiction in which such Foreign Borrower was organized, to any Foreign Currency Lender, pursuant to a Requirement of Law in force at the time such Lender becomes a party hereto (or designates a new lending office) except:

(1) to the extent that such withholding tax results from a change after the Closing Date in a Requirement of Law or in the published interpretation or administration thereof by a Governmental Authority,

(2) to the extent that such withholding tax is attributable solely to a change after the Closing Date in circumstances relating to the Foreign Borrower as a result of an action that is within the control of Airgas, the Foreign Borrower or any of their Affiliates, including, but not limited to, a change in the jurisdiction in which the relevant Foreign Borrower is resident for tax purposes or from which payments hereunder are made, or

(3) in the case of an assignment (or designation of a new lending office), to the extent that such Lender’s assignor (or, in the case of a designation of a new lending office, such Lender) was entitled at the time of assignment (or designation of a new lending office) to receive additional amounts with respect to such withholding tax pursuant to this Section 4.10(a); and

(E) any taxes imposed under Section 1471-1474 of the Code.

(ii) Gross-up for Withholding Taxes. If any taxes, levies, imposts, duties, charges, fees, deductions or withholdings other than those excluded pursuant to clauses (A), (B), (C), (D) and (E) of Section 4.10(a)(i) (“Non-Excluded Taxes”) are required to be withheld by the Borrowers or the Agent pursuant to a Requirement of Law or the published interpretation or administration thereof by a Governmental Authority from any amounts payable to the Agent or any Lender hereunder,

(A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Credit Agreement; provided, however, that the Borrowers shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable by:

(1) Airgas in its capacity as a Borrower to any Lender that is a U.S. Person, to the extent such tax is attributable to such Lender’s failure to comply with the requirements of Section 4.10(b)(i),

(2) Airgas in its capacity as a Borrower to any Lender that is not a U.S. Person, to the extent such tax is attributable to such Lender’s failure to comply with the requirements of Section 4.10(b)(ii),

(3) a Foreign Borrower to a Foreign Currency Lender if such Lender fails to comply with the requirements of Section 4.10(b)(v) or Section 4.10(c) (and, if the PTR Scheme or HMRC DT Treaty Passport Scheme is used by such Lender, the requirements of Section 4.10(f) or Section 4.10(g), as applicable), in each case whenever any Non-Excluded Taxes are payable by the Borrowers, or

(4) Airgas in its capacity as a guarantor (under Article XII) solely to the extent that the increase would leave the relevant Lender in a better after-tax position (taking into account the other provisions of this Section 4.10) than if the payment had been made by the relevant Borrower; and

(B) as promptly as possible thereafter the Borrowers shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrowers showing payment thereof (or other evidence of such payment reasonably satisfactory to the Agent). If the Borrowers fail to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrowers shall indemnify the Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. Each Lender and the Agent agrees that it will promptly refund any amounts received by it pursuant to this Section 4.10 that were erroneously billed to the Borrowers, together with interest thereon at the U.S. Base Rate.

(iii) Survival. The agreements in this Section 4.10(a) shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

(b) Certifications.

(i) Each Lender that is a U.S. Person shall deliver to Airgas and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Lender becomes a Lender under this Credit Agreement duly completed copies of Internal Revenue Service Form W-9 (or any successor form) certifying that such Lender is exempt from U.S. federal backup withholding.

(ii) Each Lender that is not a U.S. Person shall deliver to Airgas and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Lender becomes a Lender under this Credit Agreement, whichever of the following is applicable:

(A) duly completed copies of Internal Revenue Service Form W-8BEN (or any successor forms) claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(B) duly completed copies of Internal Revenue Service Form W-8ECI (or any successor forms),

(C) in the case of a Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate (any such certificate a “U.S. Tax Compliance Certificate”) to the effect that such Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of Airgas within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code, and that no payments in connection with the Credit Documents are effectively connected with such Lender’s conduct of a U.S. trade or business, and (y) duly completed copies of Internal Revenue Service Form W-8BEN (or any successor forms),

(D) to the extent a Lender is not the beneficial owner (for example, where the Lender is a partnership, or is a Lender that has granted a participation), Internal Revenue Service Form W-8IMY (or any successor forms) of the Lender, accompanied by an Internal Revenue Service Form W-8ECI, W-8BEN, Form W-9, Form W-8IMY (or other successor forms), U.S. Tax Compliance Certificate, or any other required information from each beneficial owner, as applicable (provided that, if the Lender is a partnership (and not a participating Lender) and one or more beneficial owners are claiming the portfolio interest exemption, the U.S. Tax Compliance Certificate may be provided by such Lender on behalf of such beneficial owner(s)), or

(E) any other form prescribed by applicable law as a basis for claiming an exemption from United States Federal withholding tax with respects to payments under this Credit Agreement duly completed together with such supplementary documentation as may be prescribed by applicable law (including, in the case of any Lender claiming exemption from withholding under Sections 1471-1474 of the Code, any documentation required to comply with such exemption).

(iii) Each Lender shall, from time to time after the initial delivery by such Lender of the forms described above, whenever a lapse in time or change in such Lender’s circumstances renders such forms, certificates or other evidence so delivered expired, obsolete or inaccurate, promptly (A) deliver to Airgas and the Agent (in such number of copies as shall be requested by the recipient) renewals, amendments or additional or successor forms, properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required in order to confirm or establish such Lender’s status or that such Lender is entitled to an exemption from or reduction in U.S. federal withholding tax or (B) notify the Agent and Airgas of its inability to deliver any such forms, certificates or other evidence.

(iv) Notwithstanding the foregoing clauses (i), (ii) and (iii) of this Section 4.10(b), a Lender shall not be required to deliver any form that such Lender is not legally entitled to deliver.

(v) Without limiting the foregoing, each Foreign Currency Lender shall deliver to Airgas and to the Agent, at the time or times prescribed by applicable Requirements of Law or when reasonably requested by Airgas or the Agent, such properly completed and executed documentation prescribed by applicable Requirements of Law or by the taxing authorities of any jurisdiction and such other reasonably requested information as will permit the applicable Foreign Borrower or the Agent, as the case may be, to determine (A) whether or not payments made by the respective Foreign Borrowers hereunder or under any other Credit Document are subject to Non-Excluded Taxes, (B) if applicable, the required rate of withholding or deduction, and (C) such Foreign Currency Lender’s entitlement to any available exemption from, or reduction of, applicable Non-Excluded Taxes in respect of all payments to be made to such Foreign Currency Lender by the respective Foreign Borrowers pursuant to this Credit Agreement or otherwise to establish such Foreign Currency Lender’s status for withholding tax purposes in the applicable jurisdictions. Each such Foreign Currency Lender shall, whenever a lapse in time or change in circumstances renders such documentation expired, obsolete or inaccurate in any material respect, deliver promptly to Airgas and the Agent updated or other appropriate documentation (including any new documentation reasonably requested by the applicable withholding agent) or promptly notify Airgas or the Agent of its inability to do so.

(c) Cooperation. Each Foreign Borrower shall cooperate with the Agent and the applicable Foreign Currency Lenders, and each Foreign Currency Lender shall cooperate with the relevant Foreign Borrower, in promptly completing any procedural formalities necessary for such Borrower to obtain authorization to make payments to such Foreign Currency Lenders without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court, or governmental body, agency or other official, including, without limitation, a provisional authority under the PTR Scheme and/or a direction under the HMRC DT Treaty Passport Scheme.

(d) Electivity of PTR and Passport Schemes. For the avoidance of doubt, nothing in this Section 4.10 shall require a Foreign Currency Lender to: (i) choose to use the PTR Scheme pursuant to Section 4.10(f) below; (ii) register under the HMRC DT Treaty Passport Scheme; (iii) apply the HMRC DT Treaty Passport Scheme to any Loan if it has so registered; or (iv) file double taxation agreement forms if it has indicated that it wishes the HMRC DT Treaty Passport Scheme to apply to this Credit Agreement in accordance with Section 4.10(g) below and a UK Borrower making a payment to it has not complied with its obligations under Section 4.10(g) below.

(e) U.K. Withholding. Notwithstanding any other provision herein, to the extent that the United Kingdom HM Revenue & Customs has issued a provisional authority under the PTR Scheme or a direction under the HMRC DT Treaty Passport Scheme enabling any UK Borrower to make payments to a Lender free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court, or governmental body, agency or other official in the United Kingdom (“United Kingdom Tax”), all payments made by such UK Borrower must be made free and clear of, and without deduction or withholding for or on account of, any United Kingdom Tax unless, but only to the extent that, such UK Borrower has reasonable grounds to believe that the provisional authority or direction will be cancelled or withdrawn or that double taxation relief is not available to the relevant Foreign Currency Lender.

(f) PTR Scheme. Without limiting the foregoing, and in relation to the PTR Scheme:

(i) If at any time a Foreign Currency Lender that is not subject to United Kingdom corporation tax on payments made to it under this Credit Agreement wishes to use the PTR Scheme in respect of any Foreign Currency Loan made available by it under this Credit Agreement, provided that (A) the PTR Scheme is capable of applying to such Foreign Currency Loan and (B) all Lenders in relation to that Foreign Currency Loan consent to the use of the PTR Scheme, the Lenders in relation to that Foreign Currency Loan shall agree between themselves and irrevocably appoint one such Lender to act as syndicate manager under the PTR Scheme (the “Syndicate Manager”).

(ii) Each Foreign Currency Lender in relation to a Foreign Currency Loan referred to in subsection (i) of this Section 4.10(f):

(A) authorises the Syndicate Manager to operate, and take any action necessary or desirable under, the PTR Scheme in connection with that Foreign Currency Loan;

(B) shall cooperate with the Syndicate Manager in completing any procedural formalities necessary under the PTR Scheme and shall promptly supply to the Syndicate Manager such information as the Syndicate Manager may request in connection with the operation of the PTR Scheme;

(C) without limiting the liability of any UK Borrower under this Credit Agreement, shall, within 5 Business Days of demand, indemnify the Syndicate Manager for any liability or loss incurred by the Syndicate Manager as a result of the Syndicate Manager acting as syndicate manager under the PTR Scheme in connection with the Lender’s participation in that Foreign Currency Loan (except to the extent that the liability or loss arises directly from the Syndicate Manager’s gross negligence or wilful misconduct); and

(D) shall, within ten (10) Business Days of demand, indemnify each UK Borrower and the Syndicate Manager for any United Kingdom Tax which such UK Borrower or the Syndicate Manager becomes liable to pay in respect of any payments made to such Lender arising as a result of the withdrawal of a provisional authority issued by the United Kingdom HM Revenue & Customs under the PTR Scheme, except to the extent that (1) such UK Borrower would be obliged to increase the amount payable (after payment of such United Kingdom Tax) to such Lender pursuant to Section 4.10(a) above or (2) such UK Borrower has not relied on such provisional authority and has withheld amounts in respect of United Kingdom Tax from payments to such Lender.

(iii) Each UK Borrower acknowledges that it is fully aware of its contingent obligations under the PTR Scheme and shall promptly supply to the Syndicate Manager such information as the Syndicate Manager may request in connection with the operation of the PTR Scheme.

(iv) The Syndicate Manager shall act as syndicate manager under, and operate, and take any action necessary or desirable under, the PTR Scheme in connection with the relevant Foreign Currency Loan (including, where necessary, notifying the United Kingdom HM Revenue & Customs of new Foreign Currency Lenders under this Credit Agreement) and shall provide, as soon as reasonably practicable, a copy of any provisional authority issued to it under the PTR Scheme in connection with any Foreign Currency Loan to those UK Borrowers specified in such provisional authority.

(v) All Parties acknowledge that the Syndicate Manager:

(A) is entitled to rely completely upon information provided to it in connection with subsections (ii) or (iii) of this Section 4.10(f);

(B) is not obliged to undertake any enquiry into the accuracy of such information, nor into the status of the Lender or, as the case may be, UK Borrower providing such information; and

(C) shall have no liability to any person for the accuracy of any information it submits in connection with subsection (ii)(A) of this Section 4.10(f).

(g) Passport Scheme. Without limiting the foregoing, and in relation to the HMRC DT Treaty Passport Scheme:

(i) A Foreign Currency Lender which becomes a party on the Closing Date that holds a passport under the HMRC DT Treaty Passport Scheme, and which wishes that scheme to apply to this Credit Agreement, shall include an indication to that effect (for the benefit of the Agent and without liability to any Borrower) by including its scheme reference number opposite its name in Schedule 2.1(a) (Lenders and Commitments).

(ii) Where a Lender includes the indication described in subsection (A) above in Schedule 2.1(a) (Lenders and Commitments):

(A) each UK Borrower shall, if the Closing Date is on or after 1 September 2010 and to the extent that that Foreign Currency Lender is a Lender under a Loan made available to that UK Borrower pursuant to Article III (Foreign Currency Loans), file a duly completed form DTTP-2 (or such alternative form as may be specified by the United Kingdom HM Revenue & Customs from time to time) in respect of such Lender with the United Kingdom HM Revenue & Customs within 30 days of the Closing Date and shall promptly provide the Lender with a copy of that filing; and

(B) each new Foreign Borrower designated as such pursuant to Section 3.2(b) which is a UK Borrower shall, if it becomes a Borrower on or after 1 September 2010 and to the extent that that Foreign Currency Lender is a Lender under a Loan made available to that new UK Borrower pursuant to Article III (Foreign Currency Loans), file a duly completed form DTTP-2 (or such alternative form as may be specified by the United Kingdom HM Revenue & Customs from time to time) in respect of such Lender with the United Kingdom HM Revenue & Customs within 30 days of becoming a Borrower and shall promptly provide the Lender with a copy of that filing.

(iii) A new Foreign Currency Lender that holds a passport under the HMRC DT Treaty Passport Scheme, and which wishes that scheme to apply to this Credit Agreement, shall include an indication to that effect (for the benefit of the Agent and without liability to any Borrower) in the Assignment and Assumption or other documentation which it executes to become a Lender by including its scheme reference number in such documentation.

(iv) Where a new Foreign Currency Lender includes the indication described in subsection (iii) of this Section 4.10(g) in the relevant Assignment and Assumption or other documentation which it executes to become a Lender:

(A) each UK Borrower which is a party as a Borrower as at the date on which the new Foreign Currency Lender becomes a party shall, if that date is on or after 1 September 2010 and to the extent that that Foreign Currency Lender becomes a Lender under a Loan which is made available to that UK Borrower pursuant to Article III (Foreign Currency Loans), file a duly completed form DTTP-2 (or such alternative form as may be specified by the United Kingdom HM Revenue & Customs from time to time) in respect of such Lender with the United Kingdom HM Revenue & Customs within 30 days of the date on which the new Foreign Currency Lender becomes a party and shall promptly provide the Lender with a copy of that filing; and

(B) each new Foreign Borrower designated as such pursuant to Section 3.2(b) which is a UK Borrower and which becomes a Borrower after the date on which the new Foreign Currency Lender becomes a party shall, if it becomes a Borrower on or after 1 September 2010 and to the extent that that Foreign Currency Lender becomes a Lender under a Loan which is made available to that new UK Borrower pursuant to Article III (Foreign Currency Loans), file a duly completed form DTTP-2 (or such alternative form as may be specified by the United Kingdom HM Revenue & Customs from time to time) in respect of such Lender with the United Kingdom HM Revenue & Customs within 30 days of becoming a Borrower and shall promptly provide the Lender with a copy of that filing.

(h) VAT.

(i) All amounts set out or expressed in a Credit Document to be payable by any party to a Lender or the Agent (for the purposes of this Section 4.10(h), each a “Finance Party”) which (in whole or in part) constitute the consideration for a supply or supplies for VAT purposes shall be deemed to be exclusive of any VAT which is chargeable on such supply or supplies, and accordingly, subject to subsection (ii) below, if VAT is or becomes chargeable on any supply made by any Finance Party to any party under a Credit Document and the Finance Party is accountable for such VAT, that party shall pay to the Finance Party (in addition to and at the same time as paying any other consideration for such supply) an amount equal to the amount of such VAT (and such Finance Party shall promptly provide an appropriate VAT invoice to such party).

(ii) If VAT is or becomes chargeable on any supply made by any Finance Party (the “Supplier”) to any other Finance Party (the “Recipient”) under a Credit Document, and any party other than the Recipient (the “Subject Party”) is required by the terms of any Credit Document to pay an amount equal to the consideration for such supply to the Supplier (rather than being required to reimburse the Recipient in respect of that consideration), such party shall instead pay to the Supplier if that Supplier is accountable for such VAT (in addition to and at the same time as paying such amount) an amount equal to the amount of such VAT. The Recipient will promptly pay to the Subject Party an amount equal to any credit or repayment obtained by the Recipient from the relevant tax authority which the Recipient reasonably determines is in respect of such VAT.

(iii) Where a Credit Document requires any party to reimburse or indemnify a Finance Party for any cost or expense, that party shall reimburse or indemnify (as the case may be) such Finance Party for the full amount of such cost or expense, including such part thereof as represents VAT, save to the extent that such Finance Party reasonably determines that it is entitled to credit or repayment in respect of such VAT from the relevant tax authority.

(iv) Any reference in this Section 4.10(h) to any party shall, at any time when such party is treated as a member of a group for VAT purposes, include (where appropriate and unless the context otherwise requires) a reference to the person who is treated as making or receiving the supply (as the case may be) for the purposes of any relevant VAT grouping rules.

4.11 Indemnity.

Airgas promises to indemnify (or cause the applicable Borrower to indemnify) each Lender and to hold each Lender harmless from any loss or expense (including foreign exchange losses) which such Lender may sustain or incur (other than through such Lender’s breach of its obligations hereunder, gross negligence or willful misconduct) as a consequence of (a) default by a Borrower in making a borrowing of, conversion into or continuation of Eurocurrency Loans, Quoted Rate U.S. Swingline Loans or Foreign Swingline Loans after such Borrower has given a notice requesting the same in accordance with the provisions of this Credit Agreement (or, the applicable documentation for the applicable Foreign Swingline Facility), (b) default by a Borrower in making any prepayment of a Eurocurrency Loan, a Quoted Rate U.S. Swingline Loan or a Foreign Swingline Loan after such Borrower has given a notice thereof in accordance with the provisions of this Credit Agreement (or, the applicable documentation for the applicable Foreign Swingline Facility), (c) the making of a prepayment of Eurocurrency Loans or Quoted Rate U.S. Swingline Loans on a day which is not the last day of an Interest Period with respect thereto or (d) any failure by any Borrower to make payment of any extension of credit denominated in a Foreign Currency in a different currency. With respect to Eurocurrency Loans, such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Rate included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the applicable interbank market. The covenants of Airgas set forth in this Section 4.11 shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

4.12 Payments Generally; Agent’s Clawback.

(a) General. All payments to be made by a Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, (i) all payments by the Borrowers hereunder with respect to principal and interest on Foreign Currency Loans denominated in a Foreign Currency shall be made to the Agent, for the account of the respective Lenders to which such payment is owed, at the applicable Agent’s office in such Foreign Currency and in Same Day Funds not later than the Applicable Time specified by the Agent on the date specified herein, and (ii) all other payments hereunder shall be made to the Agent, for the account of the respective Lenders to which such payment is owed, at the Agent’s office specified in Schedule 11.1 in U.S. Dollars and in immediately available funds not later than 2:00 P.M. on the date specified herein. Without limiting the generality of the foregoing, the Agent may require that any payments due under this Credit Agreement be made in the United States. If, for any reason, any Borrower is prohibited by any Requirement of Law from making any required payment hereunder in a Foreign Currency, such Borrower shall make such payment in U.S. Dollars in the U.S. Dollar Equivalent (using the applicable Spot Rate determined as of the date of the applicable payment) of the Foreign Currency payment amount. All payments received by the Agent after such times shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. The Agent may (but shall not be obligated to) debit the amount of any such payment which is not made by such time to any ordinary deposit account of the applicable Borrower maintained with the Agent (with notice to such Borrower). The Agent

will promptly distribute to each Lender its pro rata share (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender. Subject to the definition of “Interest Period”, if any payment to be made by a Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be. All payments of principal and interest in respect of Foreign Swingline Loans shall be in accordance with Section 3.3.

(b) (i) Funding by Lenders; Presumption by Agent. Unless the Agent shall have received notice from a Lender prior to the proposed date of any extension of credit that such Lender will not make available to the Agent such Lender’s share of such extension of credit, the Agent may assume that such Lender has made such share available on such date in accordance with the terms of this Credit Agreement and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable extension of credit available to the Agent, then the applicable Lender and the applicable Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Agent, at (A) in the case of a payment to be made by such Lender in connection with any extension of credit, the applicable Overnight Rate, and (B) in the case of a payment to be made by a Borrower in connection with any extension of credit in U.S. Dollars or a Foreign Currency, the interest rate otherwise applicable to such credit extension. If such Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping period, the Agent shall promptly remit to such Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays its share of the applicable extension of credit to the Agent, then the amount so paid shall constitute such Lender’s Loan included in such extension of credit. Any payment by a Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Agent.

(ii) Payments by Borrowers; Presumptions by Agent. Unless the Agent shall have received notice from the applicable Borrower prior to the date on which any payment is due to the Agent for the account of the Lenders hereunder that such Borrower will not make such payment, the Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the appropriate Lenders the amount due. In such event, if such Borrower has not in fact made such payment, then each of the applicable Lenders severally agrees to repay to the Agent forthwith on demand the amount so distributed to such Lender, in Same Day Funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Agent, at the Overnight Rate.

A notice of the Agent to any Lender or a Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Agent funds for any extension of credit to be made by such Lender as provided in this Credit Agreement, and such funds are not made available to the applicable Borrower by the Agent because the conditions to the applicable extension of credit set forth in Section 5.2 are not satisfied or waived in accordance with the terms hereof, the Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans, to fund participations in other extensions of credit and to make payments pursuant to Section 11.5(b) are several and not joint. The failure of any Lender to make any Loan, to fund any such

participation or to make any payment under Section 11.5(b) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 11.5(b).

(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any extension of credit hereunder in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any such extension of credit in any particular place or manner.

4.13 Sharing of Payments.

If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans made by it, or the participations in U.S. LOC Obligations, in U.S. Swingline Loans or in Foreign Swingline Loans held by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Loans or participations and accrued interest thereon greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and subparticipations in U.S. LOC Obligations, U.S. Swingline Loans or Foreign Swingline Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

(i) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(ii) the provisions of this Section 4.13 shall not be construed to apply to (x) any payment made by a Borrower pursuant to and in accordance with the express terms of this Credit Agreement (including the application of funds arising from the existence of a Defaulting Lender), (y) the application of Cash Collateral provided for in Section 4.15, or (z) any payment obtained by a Lender as consideration for any assignment of or sale of any of its interests hereunder in accordance with Section 11.3, other than to a Borrower or any Subsidiary thereof (as to which the provisions of this Section 4.13 shall apply).

Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

4.14 Computations of Interest and Fees.

All computations of interest for U.S. Base Rate Loans shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. Except as expressly provided otherwise herein, all other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year), or, in the case of interest in respect of Foreign Currency Loans denominated in Foreign Currencies as to which market practice differs from the foregoing, in accordance with such market practice. Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 4.12(a), bear interest for one day. Each determination by the Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

For the purposes of the Interest Act (Canada), (i) whenever a rate of interest or fee rate hereunder is calculated on the basis of a year (the “deemed year”) that contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest or fee rate shall be expressed as a yearly rate by multiplying such rate of interest or fee rate by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year, (ii) the principle of deemed reinvestment of interest shall not apply to any interest calculation hereunder and (iii) the rates of interest stipulated herein are intended to be nominal rates and not effective rates or yields.

4.15 Cash Collateral.

(a) Certain Credit Support Events. Upon the request of the Agent or the U.S. Issuing Lender if, as of the date that is seven (7) Business Days prior to the Maturity Date, any U.S. LOC Obligation for any reason remains outstanding, Airgas shall immediately Cash Collateralize the then outstanding amount of all U.S. LOC Obligations. At any time that there shall exist a Defaulting Lender, immediately upon the request of the Agent, the U.S. Issuing Lenders, the U.S. Swingline Lender or the Foreign Swingline Lenders, Airgas or the applicable Borrowers shall deliver to the Agent Cash Collateral in an amount sufficient to cover all applicable Fronting Exposure (after giving effect to Section 4.16(a)(iv) and any Cash Collateral provided by the Defaulting Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America (provided that Cash Collateral pledged by Airgas to reduce Fronting Exposure shall be maintained in interest bearing accounts, with interest earned for the account of Airgas). The Borrowers, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Agent, for the benefit of the Agent, the U.S. Issuing Lenders and the Lenders (including the U.S. Swingline Lender and the Foreign Swingline Lenders), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 4.15(c). If at any time the Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, Airgas, the applicable Borrowers or the relevant Defaulting Lender will, promptly upon demand by the Agent, pay or provide to the Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(c) Application. Notwithstanding anything to the contrary contained in this Credit Agreement, Cash Collateral provided under any of this Section 4.15 or Sections 2.2, 2.3, 3.3, 4.3, 4.16 or 9.2 in respect of U.S. Letters of Credit, U.S. Swingline Loans or Foreign Swingline Loans shall be held and applied to the satisfaction of the specific U.S. LOC Obligations, U.S. Swingline Loans, Foreign Swingline Loans, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 11.3(i)) or (ii) the Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Borrower shall not be released during the

continuance of a Default or Event of Default (and following application as provided in this Section 4.15 may be otherwise applied in accordance with Section 9.3), and (y) the Person providing Cash Collateral and the U.S. Issuing Lenders, U.S. Swingline Lender or Foreign Swingline Lenders, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

4.16 Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Credit Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Requirement of Law:

(i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Credit Agreement shall be restricted as set forth in Section 11.6.

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 9.3 or otherwise, and including any amounts made available to the Agent by that Defaulting Lender pursuant to Section 11.2), shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the U.S. Issuing Lenders, U.S. Swingline Lender or Foreign Swingline Lenders hereunder (as applicable); third, if so determined by the Agent or requested by the U.S. Issuing Lenders, U.S. Swingline Lender or Foreign Swingline Lenders (as applicable), to be held as Cash Collateral for future funding obligations of that Defaulting Lender of any participation in any U.S. Swingline Loan, Foreign Swingline Loan or U.S. Letter of Credit (as applicable); fourth, as Airgas may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Credit Agreement, as determined by the Agent; fifth, if so determined by the Agent and Airgas, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Credit Agreement; sixth, to the payment of any amounts owing to the Lenders, the U.S. Issuing Lenders, U.S. Swingline Lender or Foreign Swingline Lenders (as applicable) as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the U.S. Issuing Lenders, U.S. Swingline Lender or Foreign Swingline Lenders against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Credit Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrowers as a result of any judgment of a court of competent jurisdiction obtained by the Borrowers against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Credit Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or participation in any U.S. Letter of Credit in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans or participations in U.S. Letters of Credit were made at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and funded participations in any U.S. Letters of Credit owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or funded participations in any U.S. Letters of Credit owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 4.16(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. That Defaulting Lender (x) shall not be entitled to receive any U.S. Revolving Commitment Unused Fee for any period during which that Lender is a Defaulting Lender (and Airgas shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender), (y) shall not be entitled to receive any Foreign Currency Commitment Unused Fee for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) and (z) shall be limited in its right to receive letter of credit fees as provided in Sections 4.5(b)(i) and 4.5(b)(ii)).

(iv) Reallocation of Applicable Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in U.S. Letters of Credit, U.S. Swingline Loans or Foreign Swingline Loans pursuant to Sections 2.2, 2.3 and 3.3, the “Applicable Percentage” of each non-Defaulting Lender shall be computed without giving effect to the U.S. Revolving Commitment or Foreign Currency Commitment (as applicable) of that Defaulting Lender; provided, that (A) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in U.S. Letters of Credit and U.S. Swingline Loans shall not exceed the positive difference, if any, of (1) the U.S. Revolving Commitment of that non-Defaulting Lender minus (2) the aggregate outstanding principal amount of the U.S. Revolving Loans of that U.S. Revolving Lender and (B) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Foreign Swingline Loans shall not exceed the positive difference, if any, of (1) the Foreign Currency Commitment of that non-Defaulting Lender minus (2) the aggregate outstanding principal amount of the Foreign Currency Loans of that Foreign Currency Lender.

(b) Defaulting Lender Cure. If Airgas, the Agent, the U.S. Swingline Lender, the Foreign Swingline Lenders and the U.S. Issuing Lenders (as applicable) agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Agent may determine to be necessary to cause the Loans and funded and unfunded participations in U.S. Letters of Credit, U.S. Swingline Loans and Foreign Swingline Loans (as applicable) to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 4.16(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

4.17 Mitigation Obligations.

If any Lender requests compensation under Section 4.9, or any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.10, or if any Lender gives a notice pursuant to Section 4.8, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable

pursuant to Section 4.9 or 4.10, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 4.8, as applicable, and (ii) in each case, would not subject such Lender to any unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Lender. Airgas hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. If any Lender requests compensation under Section 4.9, or if any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.10, Airgas may replace such Lender in accordance with Section 11.17.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES

Airgas hereby represents to the Agent and each Lender that:

6.1 Financial Condition.

(a) The audited consolidated balance sheet of the Consolidated Parties, and the related consolidated statements of earnings and statements of cash flows, as of March 31, 2010 have heretofore been furnished to each Lender. Such financial statements (including the notes thereto) (i) have been audited by KPMG LLP, (ii) have been prepared in accordance with GAAP consistently applied throughout the periods covered thereby and (iii) present fairly (on the basis disclosed in the footnotes to such financial statements) the consolidated financial condition, results of operations and cash flows of the Consolidated Parties as of such date and for such periods.

9.2 Acceleration; Remedies.

Upon the occurrence of an Event of Default, and at any time thereafter unless and until such Event of Default has been waived by, or cured to the satisfaction of, the requisite Lenders (pursuant to the voting procedures in Section 11.6), the Agent shall, upon the request and direction of the Required Lenders, by written notice to Airgas take any of the following actions:

(i) Termination of Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) with respect to a Borrower (or in which a Borrower is named as a debtor) shall occur, then the Commitments shall automatically terminate and all Loans, all reimbursement obligations arising from drawings under U.S. Letters of Credit, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Agent and/or any of the Lenders hereunder automatically shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

9.3 Allocation of Payments After Acceleration.

After acceleration of the Obligations pursuant to Section 9.2, all amounts collected or received by the Agent or any Lender from the Borrowers in connection with or on account of the Obligations or any other amounts outstanding under any of the Credit Documents, whether received from a Borrower or otherwise shall be immediately forwarded to the Agent and shall be thereafter be paid over or delivered as follows:

SEVENTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing:

(i) to the extent that any amounts available for distribution pursuant to clause “FIFTH” above are attributable to the issued but undrawn amount of outstanding U.S. Letters of Credit, such amounts shall be held by the Agent in a cash collateral account and applied (A) first, to reimburse the applicable U.S. Issuing Lender from time to time for any drawings under such U.S. Letters of Credit and (B) then, following the expiration or cancellation of all U.S. Letters of Credit, to all other obligations of the types described in clauses “FIFTH”, “SIXTH” and “SEVENTH” above in the manner provided in this Section 9.3;

The provisions of this Article X are solely for the benefit of the Agent and the Lenders, and neither Airgas nor any other Borrower shall have rights as a third party beneficiary of any of such provisions.

10.2 Rights as a Lender.

Any Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include any Person serving as the Agent hereunder in its individual capacity. Any such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Airgas or any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Lenders.

10.3 Exculpatory Provisions.

The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, the Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit Documents), provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Credit Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and shall be liable for the failure to disclose, any information relating to Airgas or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 11.6 and 9.2) or (ii) in the absence of its own gross negligence or willful misconduct. The Agent shall not be deemed to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Agent by Airgas or a Lender.

The Agent shall not be responsible for nor have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Credit Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Credit Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, the issuance of a U.S. Letter of Credit or the making of any other extension of credit hereunder, that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that such condition is satisfactory to such Lender unless the Agent shall have received notice to the contrary from such Lender prior to the making of such Loan, the issuance of such U.S. Letter of Credit or the making of such other extension of credit. The Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

10.5 Delegation of Duties.

The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Agent. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by

or through their respective Related Parties. The exculpatory provisions of this Article X shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Agent.

10.6 Resignation of Agent.

The Agent may at any time give notice of its resignation to the Lenders and Airgas. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with Airgas, to appoint a successor, which, in the case of a successor Agent, shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders, appoint a successor Agent meeting the qualifications set forth above; provided that if the Agent shall notify Airgas and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents and (2) all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as the Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this Section). The fees payable by Airgas to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between Airgas and such successor. After a retiring Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article X and Section 11.5 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as the Agent.

Any resignation by Bank of America as Agent pursuant to this Section shall also constitute its resignation as U.S. Swingline Lender (and, if applicable, as a U.S. Issuing Lender and, if Bank of America (or an Affiliate) is a Foreign Swingline Lender, such Foreign Swingline Lender). Upon the acceptance of a successor’s appointment as Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of such retiring U.S. Swingline Lender (and, if applicable, retiring U.S. Issuing Lender or retiring Foreign Swingline Lender), (b) such retiring U.S. Swingline Lender (and, if applicable, retiring U.S. Issuing Lender or retiring Foreign Swingline Lender) shall be discharged from all of their respective duties and obligations hereunder or under the other Credit Documents, and (c) if Bank of America is also a retiring U.S. Issuing Lender, the successor U.S. Issuing Lender shall issue letters of credit in substitution for the U.S. Letters of Credit, if any, outstanding at the time of such succession or make other arrangement satisfactory to the retiring U.S. Issuing Lender to effectively assume the obligations of the retiring U.S. Issuing Lender with respect to such U.S. Letters of Credit.

10.7 Non-Reliance on Agent and Other Lenders.

Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Credit Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Credit Agreement, any other Credit Document or any related agreement or any document furnished hereunder or thereunder.

10.8 No Other Duties; Etc.

Anything herein to the contrary notwithstanding, none of the bookrunners, arrangers, syndication agents, documentation agents or co-agents shall have any powers, duties or responsibilities under this Credit Agreement or any of the other Credit Documents, except in its capacity, as applicable, as the Agent or a Lender hereunder.

10.9 Agent May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Borrower, the Agent (irrespective of whether the principal of any Loan, U.S. LOC Obligation or other extension of credit hereunder shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Agent shall have made any demand on any Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, U.S. LOC Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Agent and their respective agents and counsel and all other amounts due the Lenders and the Agent under Sections 4.5 and 11.5) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Agent and, in the event that the Agent shall consent to the making of such payments directly to the Lenders, to pay to the Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Agent and its agents and counsel, and any other amounts due the Agent under Sections 4.5 and 11.5.

Nothing contained herein shall be deemed to authorize the Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Agent to vote in respect of the claim of any Lender in any such proceeding.

Unless the Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), provided that if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient, and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor.

(c) Change of Address, Etc. Each of Airgas, the Agent, a U.S. Issuing Lender, the U.S. Swingline Lender and a Foreign Swingline Lender may change its address, telecopier or telephone number for notices and other communications hereunder by notice to the other parties hereto. Each other Lender may change its address, telecopier or telephone number for notices and other communications hereunder by notice to Airgas and the Agent and, in the case of any U.S. Revolving Lender, the U.S. Issuing Lenders and the U.S. Swingline Lender. In addition, each Lender agrees to notify the Agent from time to time to ensure that the Agent have on record (i) an effective address, contact name, telephone number, telecopier number and electronic mail address to which notices and other communications may be sent and (ii) accurate wire instructions for such Lender.

(d) Reliance. The Agent and the Lenders shall be entitled to rely and act upon any notices (including telephonic Notices of Borrowing) purportedly given by or on behalf of any Borrower even if (i)

such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrowers shall indemnify the Agent, each Lender and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of a Borrower. All telephonic notices to and other telephonic communications with the Agent may be recorded by the Agent, and each of the parties hereto hereby consents to such recording.

(e) The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event shall the Agent or any of its Related Parties (collectively, the “Agent Parties”) have any liability to the Borrowers, any Lender, the U.S. Issuing Lender or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) arising out of any Borrower’s or the Agent’s transmission of Borrower Materials through the Internet, except to the extent that such losses, claims, damages, liabilities or expenses are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Agent Party; provided, however, that in no event shall any Agent Party have any liability to the Borrowers, any Lender, the Issuing Lender or any other Person for indirect, special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

11.2 Right of Set-Off.

If an Event of Default shall have occurred and be continuing, each Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of Airgas or any other Borrower against any and all of the obligations of Airgas or such Borrower now or hereafter existing under this Credit Agreement or any other Credit Document to such Lender, irrespective of whether or not such Lender shall have made any demand under this Credit Agreement or any other Credit Document and although such obligations of Airgas or such Borrower may be contingent or unmatured or are owed to a branch or office of such Lender different from the branch or office holding such deposit or obligated on such indebtedness; provided, that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Agent for further application in accordance with the provisions of Section 4.16 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender agrees to notify Airgas and the Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

11.3 Benefit of Agreement.

(a) Successors and Assigns Generally. The provisions of this Credit Agreement and the other Credit Documents shall be binding upon and inure to the benefit of the parties hereto and thereto and their respective successors and assigns permitted hereby, except that no Borrower may assign or otherwise transfer any of its rights or obligations hereunder or thereunder without the prior written consent of the Agent and each affected Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Credit Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Credit Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Credit Agreement and the other Credit Documents (including all or a portion of its Commitment and the Loans (including for purposes of this subsection (b), participations in U.S. LOC Obligations, in U.S. Swingline Loans and in Foreign Swingline Loans) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, no minimum amount need be assigned;

(B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes outstanding Loans thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 in the case of an assignment of U.S. Revolving Loans or Foreign Currency Loans unless each of the Agent and, so long as no Event of Default has occurred and is continuing, Airgas otherwise consents (each such consent not to be unreasonably withheld or delayed);

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations hereunder, assigned, except that this subsection (b)(ii) shall not apply to rights in respect of U.S. Swingline Loans or Foreign Swingline Loans;

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

(A) the consent of Airgas (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender with a Commitment in respect of the Commitment subject to such assignment, an Affiliate of such Lender or an Approved Fund with respect to such Lender;

(C) the consent of each U.S. Issuing Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more U.S. Letters of Credit (whether or not then outstanding); and

(D) the consent of the U.S. Swingline Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment in respect of U.S. Revolving Loans and U.S. Revolving Commitments.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with (in cases other than an assignment to an Affiliate of the assigning Lender) a processing and recordation fee of $3,500 (payable by the assignor or assignee), and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) Airgas or any of Airgas’ Affiliates or Subsidiaries, (B) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) a natural person.

(vi) Additional Limitation with respect to Foreign Currency Commitments. In the case of any assignment of any Foreign Currency Commitment (and the related Foreign Currency Loans), no such assignment shall be made to (A) any Person that, through its applicable lending offices, is not capable (subject to the completion of any necessary procedural formalities) of lending U.S. Dollars or the Foreign Currencies as of the effective date of such assignment to Airgas or the Foreign Borrowers, as the case may be, without the imposition of additional withholding taxes (unless Airgas otherwise agrees in writing) and (B) at such times as there is a Dutch Borrower, any Person that does not qualify as a PMP.

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of Airgas and the Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in U.S. Letters of Credit, U.S. Swingline Loans and Foreign Swingline Loans (as applicable) in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Requirements of Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Credit Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Credit Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Credit Agreement, and the assigning

Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Credit Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Credit Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 4.6, 4.9, 4.10, 4.11 and 11.5 with respect to facts and circumstances occurring prior to the effective date of such assignment). Any assignment or transfer by a Lender of rights or obligations under this Credit Agreement that does not comply with this subsection shall be treated for purposes of this Credit Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c) Register. The Agent, acting solely for this purpose as an agent of the applicable Borrowers, shall maintain at its office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans and U.S. LOC Obligations owing to, each applicable Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Credit Agreement, notwithstanding notice to the contrary. In addition, the Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The Register shall be available for inspection by the Borrowers, the U.S. Issuing Lenders and any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Agent, sell participations to any Person (other than a natural person or a Borrower or any of the Borrowers’ Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Credit Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in U.S. LOC Obligations, U.S. Swingline Loans and/or Foreign Swingline Loans) owing to it); provided that (i) such Lender’s obligations under this Credit Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Credit Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Credit Agreement and to approve any amendment, modification or waiver of any provision of this Credit Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in clauses (i) through (viii) of Section 11.6(a) that affects such Participant. Subject to subsection (e) of this Section, Airgas agrees that each Participant shall be entitled to the benefits of Sections 4.6, 4.9, 4.10, 4.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.2 as though it were a Lender, provided such Participant agrees to be subject to Section 4.13 as though it were a Lender.

(e) Limitation on Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 4.6, 4.9, 4.10 or 4.11 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with Airgas’ prior written consent. A Participant that is not a U.S. Person shall not be entitled to the benefits of Section 4.10 unless Airgas is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 4.10(b) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Credit Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

(h) Resignation as by Bank of America from Other Capacities after Assignment. Notwithstanding anything to the contrary contained herein, (i) if at any time Bank of America assigns all of its U.S. Revolving Commitment pursuant to subsection (b) above, Bank of America may (A) if Bank of America is a U.S. Issuing Lender, upon thirty days’ notice to Airgas and the Lenders, resign as a U.S. Issuing Lender and/or (B) upon thirty days’ notice to Airgas, resign as U.S. Swingline Lender and (ii) if at any time Bank of America assigns all of its Foreign Currency Commitment pursuant to subsection (b) above, if Bank of America is a Foreign Swingline Lender, upon thirty days’ notice to Airgas and the Lenders, resign as a Foreign Swingline Lender. In the event of any such resignation, Airgas shall be entitled to appoint from among the Lenders a successor hereunder; provided, however, that no failure by Airgas to appoint any such successor shall affect any such resignation of Bank of America. If Bank of America resigns as a U.S. Issuing Lender, it shall retain all the rights and obligations of a U.S. Issuing Lender hereunder with respect to all U.S. Letters of Credit outstanding as of the effective date of its resignation as a U.S. Issuing Lender and all U.S. LOC Obligations with respect thereto (including the right to require the U.S. Revolving Lenders to make U.S. Base Rate Loans or fund risk participations in unreimbursed drawings under U.S. Letters of Credit pursuant to Section 2.2(c)). If Bank of America resigns as U.S. Swingline Lender, it shall retain all the rights of the U.S. Swingline Lender provided for hereunder with respect to U.S. Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the U.S. Revolving Lenders to make U.S. Base Rate Loans or fund risk participations in outstanding U.S. Swingline Loans pursuant to Section 2.3(b). If Bank of America resigns as a Foreign Swingline Lender, it shall retain all the rights of a Foreign Swingline Lender provided for hereunder with respect to Foreign Swingline Loans made by it (or its Affiliates) and outstanding as of the effective date of such resignation, including the right to require the Foreign Currency Lenders to make U.S. Base Rate Loans or fund risk participations in outstanding Foreign Swingline Loans pursuant to Section 3.3(d).

11.4 No Waiver; Remedies Cumulative.

No failure or delay on the part of the Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Agent or any Lender and the Borrowers shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies which the Agent or any Lender would otherwise have. No notice to or demand on the Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent or the Lenders to any other or further action in any circumstances without notice or demand.

11.5 Payment of Expenses, Etc.

(a) The Borrowers agree to: (i) pay all reasonable out-of-pocket costs and expenses (A) of the Agent in connection with the negotiation, preparation, execution and delivery and administration of this Credit Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, the reasonable fees and expenses of counsel to the Agent (other than fees and expenses of counsel identified in writing by Airgas to the Agent on the Closing Date (hereinafter, “Disqualified Counsel”))) and any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrowers under this Credit Agreement and (B) of the Agent and the Lenders in connection with enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent and each of the Lenders (other than fees and expenses of Disqualified Counsel)); (ii) pay and hold the Agent and each of the Lenders harmless from and against any and all present and future stamp and other similar taxes with respect to the foregoing matters and save each of the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to such Lender) to pay such taxes; and (iii) indemnify the Agent, each Lender, its officers, directors, employees, representatives and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of (A) any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) occurring subsequent to and as the result of the occurrence of a Default or Event of Default and related to the entering into and/or performance of any Credit Document or the use of proceeds of any Loans (including other extensions of credit) hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding or (B) the presence or Release of any Materials of Environmental Concern at, under or from any Property owned, operated or leased by any Consolidated Party, or the failure by any Consolidated Party to comply with any Environmental Law (but excluding, in the case of either of clause (A) or (B) above, any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified).

(b) Reimbursement by Lenders. To the extent that the Borrowers for any reason fail to indefeasibly pay any amount required under Section 11.5(a) to be paid by them to the Agent (or any sub-agent thereof) or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Agent (or any such sub-agent) or such Related Party, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent (or any such sub-agent) in its capacity as such, or against any Related Party of any of the foregoing acting for the Agent (or any such sub-agent) in connection with such capacity. The obligations of the Lenders under this Section 11.5(b) are subject to the provisions of Section 4.12(d).

(c) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, no party hereto shall assert, and each party hereto hereby waives, any claim against any other party hereto or any other Person to be indemnified under Section 11.5(a), on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Credit Agreement, any other Credit Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan, U.S. Letter of Credit or other extension of credit hereunder or the use of the proceeds thereof. No Person to be indemnified under Section 11.5(a) shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Credit Agreement or the other Credit Documents or the transactions contemplated hereby or thereby.

(d) Payments. All amounts due under this Section shall be payable not later than thirty Business Days after demand therefor.

(e) Survival. The agreements in this Section shall survive the resignation of the Agent, the replacement of any Lender, the termination of the Commitments of all the Lenders and the repayment, satisfaction or discharge of all the other Obligations.

(a) no such amendment, change, waiver, discharge or termination shall:

(iii) reduce the principal amount on any Loan or of any reimbursement obligations arising from drawings under U.S. Letters of Credit or the amount of any accrued interest or fees, or increase the Commitment of any Lender over the amount thereof in effect without the written consent of each Lender entitled to receive such payment or each Lender whose Commitment is being increased (it being understood and agreed that a waiver of any Default or Event of Default or of a mandatory reduction in the total commitments shall not constitute a change in the terms of any Commitment of any Lender);

(b) Each Borrower hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Credit Agreement or any other Credit Document brought in the courts referred to in subsection (a) hereof and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

(i) Without limiting the generality of subsections (a) and (b) of this Section 11.10, each such Borrower agrees that any controversy or claim with respect to it arising out of or relating to this Credit Agreement or the other Credit Documents may, at the option of the Agent and the Foreign Currency Lenders, in the case of claims or controversies with respect to Foreign Borrowers, be settled immediately by submitting the same to binding arbitration in the City of New York, New York (or such other place as the parties may agree) in accordance with the Commercial Arbitration Rules then obtaining of the American Arbitration Association. Upon the request and submission of any controversy or claim for arbitration hereunder, the Agent shall give the applicable Borrowers not less than 45 days written notice of the request for arbitration, the nature of the controversy or claim, and the time and place set for arbitration. Each Foreign Borrower agrees that such notice is reasonable to enable it sufficient time to prepare and

present its case before the arbitration panel. Judgment on the award rendered by the arbitration panel may be entered in any court in which any action could have been brought or maintained pursuant to subparagraph (iii) below, including without limitation any court of the State of New York or any Federal court sitting in the State of New York. The expenses of arbitration shall be paid by the Foreign Borrowers.

(ii) The provisions of subparagraph (i) above are intended to comply with the requirements of the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the “Convention”). To the extent that any provisions of such subparagraph (i) are not consistent with or fail to conform to the requirements set out in the Convention, such subparagraph (i) shall be deemed amended to conform to the requirements of the Convention.

(iii) Each Foreign Borrower hereby specifically consents and submits to the jurisdiction of the courts of the State of New York and courts of the United States located in the State of New York for purposes of entry of a judgment or arbitration award entered by the arbitration panel.

(d) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

11.11 Severability.

If any provision of any of the Credit Documents is determined to be illegal, invalid or unenforceable, such provision shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions. Without limiting the foregoing provisions of this Section 11.11, if and to the extent that the enforceability of any provisions in this Credit Agreement relating to Defaulting Lenders shall be limited by any Bankruptcy Code, as determined in good faith by the Agent, the U.S. Issuing Lenders, the U.S. Swingline Lender or the Foreign Swingline Lenders, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

11.12 Entirety.

This Credit Agreement together with the other Credit Documents represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Credit Documents or the transactions contemplated herein and therein.

11.13 Binding Effect; Termination.

(a) This Credit Agreement shall become effective at such time on or after the Closing Date and satisfaction of the conditions precedent set forth in Section 5.1 when it shall have been executed by the Borrowers and the Agent, and the Agent shall have received copies hereof (telefaxed or otherwise) which, when taken together, bear the signatures of each Lender, and thereafter this Credit Agreement shall be binding upon and inure to the benefit of the Borrowers, the Agent and each Lender and their respective successors and assigns. Airgas and the Lenders party to the Existing Credit Agreement each hereby agrees that, at such time as this Credit Agreement shall have become effective pursuant to the terms of the immediately preceding sentence, (i) the Existing Credit Agreement and the Commitments thereunder and as defined therein automatically shall be terminated and (ii) all of the promissory notes, if any, executed by Airgas in connection with the Existing Credit Agreement automatically shall be canceled.

(b) The term of this Credit Agreement shall be until no Loans, U.S. LOC Obligations or any other amounts payable hereunder or under any of the other Credit Documents shall remain outstanding and until all of the Commitments hereunder shall have expired or been terminated.

11.14 Confidentiality.

Each of the Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives and to any direct or indirect contractual counterparty (or such contractual counterparty’s professional advisor) under any Hedging Agreement relating to Loans outstanding under this Credit Agreement (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it and including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Credit Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Credit Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to a Borrower and its obligations, (g) with the written consent of Airgas or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent, any Lender or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrowers.

For purposes of this Section, “Information” means all information received from a Borrower or any Subsidiary relating to the Borrowers or any Subsidiary or any of their respective businesses, other than any such information that is available to the Agent or any Lender on a nonconfidential basis prior to disclosure by such Borrower or any Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

11.15 Conflict.

To the extent that there is a conflict or inconsistency between any provision hereof, on the one hand, and any provision of any Credit Document, on the other hand, this Credit Agreement shall control.

11.16 USA PATRIOT Act Notice.

Each Lender that is subject to the Act (as hereinafter defined) and the Agent that is subject to the Act (for itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such Lender or the Agent, as applicable, to identify the Borrowers in accordance with the Act.

11.17 Replacement of Lenders.

If (i) any Lender requests compensation under Sections 4.6 or 4.9, (ii) any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.10, (iii) any Lender is a Defaulting Lender or (iv) if any Lender refuses to consent to an amendment, modification and/or waiver of this Credit Agreement, then Airgas may, at its sole expense and effort, upon notice to such Lender and the Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.3), all of its interests, rights and obligations under this Credit Agreement and the related Credit Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) Airgas shall have paid to the Agent the assignment fee specified in Section 11.3(b);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Sections 4.6, 4.9, 4.10 and 4.11) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the applicable Borrower (in the case of all other amounts);

(c) in the case of any such assignment resulting from a claim for compensation under Section 4.6 or 4.9 or payments required to be made pursuant to Section 4.10, such assignment will result in a reduction in such compensation or payments thereafter;

(d) such assignment does not conflict with applicable laws; and

(e) in the case of any replacement of Lenders under the circumstances described in clause (iv) above, the applicable amendment, modification and/or waiver of this Credit Agreement that Airgas has requested shall become effective upon giving effect to such assignment (and any related assignments required to be effected in connection therewith in accordance with this Section 11.17).

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Airgas to require such assignment and delegation cease to apply.

11.18 No Advisory or Fiduciary Responsibility.

In connection with all aspects of each transaction contemplated hereby, the Borrowers each acknowledge and agree that: (i) the credit facilities provided for hereunder and any related arranging or other services in connection therewith (including in connection with any amendment, waiver or other modification hereof or of any other Credit Document) are an arm’s-length commercial transaction between the Borrowers and their respective Affiliates, on the one hand, and the Agent, BAS and Wells

Fargo Securities, LLC (“WFS”, together with BAS, the “Arrangers”), on the other hand, and each of the Borrowers is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Credit Documents (including any amendment, waiver or other modification hereof or thereof); (ii) in connection with the process leading to such transaction, the Agent and the Arrangers each is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary, for the Borrowers or any of their respective Affiliates, stockholders, creditors or employees or any other Person; (iii) neither the Agent nor the Arrangers have assumed or will assume an advisory, agency or fiduciary responsibility in favor of any Borrower with respect to any of the transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Credit Document (irrespective of whether the Agent or the Arrangers have advised or is currently advising any of the Borrowers or any of their respective Affiliates on other matters) and neither the Agent nor the Arrangers have any obligation to any of the Borrowers or any of their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Credit Documents; (iv) the Agent and the Arrangers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrowers and their respective Affiliates, and neither the Agent nor the Arrangers have any obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Agent and the Arrangers have not provided and will not provide any legal, accounting, regulatory or tax advice with respect to any of the transactions contemplated hereby (including any amendment, waiver or other modification hereof or of any other Credit Document) and each Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate. Each Borrower hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Agent and the Arrangers with respect to any breach or alleged breach of agency or fiduciary duty.

11.19 Judgment Currency.

If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or under any other Credit Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Agent could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given. The obligation of each Borrower in respect of any such sum due from it to the Agent or the Lenders hereunder or under the other Credit Documents shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Credit Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Agent of any sum adjudged to be so due in the Judgment Currency, the Agent may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Agent from any Borrower in the Agreement Currency, such Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Agent or the Person to whom such obligation was owing against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Agent in such currency, the Agent agrees to return the amount of any excess to such Borrower (or to any other Person who may be entitled thereto under applicable law).

11.20 Payments Set Aside.

To the extent that any payment by or on behalf of any Borrower is made to the Agent, the U.S. Issuing Lender or any Lender, or the Agent, the U.S. Issuing Lender or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Agent, the U.S. Issuing Lender or such Lender in its discretion) to be repaid to a

trustee, receiver or any other party, in connection with any Bankruptcy Event or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender and the U.S. Issuing Lender severally agrees to pay to the Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders and the U.S. Issuing Lender under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Credit Agreement.

11.21 Interest Rate Limitation.

Notwithstanding anything to the contrary contained in any Credit Document, the interest paid or agreed to be paid under the Credit Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable law or result in receipt by a Lender of interest at a criminal rate (as construed under the Criminal Code (Canada) (such maximum rate or such criminal rate, as applicable, the “Maximum Rate”). If the Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the applicable Borrower. In determining whether the interest contracted for, charged, or received by the Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

ARTICLE XII

GUARANTY

12.1 The Guaranty.

Airgas hereby guarantees to each holder of Foreign Obligations as hereinafter provided, as primary obligor and not as surety, the prompt payment of the Foreign Obligations in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory Cash Collateralization or otherwise) strictly in accordance with the terms thereof. Airgas hereby further agrees that if any of the Foreign Obligations are not paid in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory Cash Collateralization or otherwise), Airgas will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Foreign Obligations, the same will be promptly paid in full when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a mandatory Cash Collateralization or otherwise) in accordance with the terms of such extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other of the Credit Documents, the obligations of Airgas under this Article XII shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under Section 548 of the Bankruptcy Code of the United States, if applicable, or any comparable provisions of any other applicable Bankruptcy Code.

12.2 Obligations Unconditional.

The obligations of Airgas under Section 12.1 with respect to the Foreign Obligations are absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of any of the

Credit Documents or any other agreement or instrument referred to therein, or any substitution, release, impairment or exchange of any other guarantee of or security for any of the Foreign Obligations and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 12.2 that the respective obligations of Airgas hereunder shall be absolute and unconditional under any and all circumstances. Airgas agrees that it shall have no right of subrogation, indemnity, reimbursement or contribution against the applicable Borrower or any other Borrower for amounts paid under this Article XII until such time as the Lenders have been paid in full in respect of all Obligations, all Commitments under this Credit Agreement have been terminated and no Person or Governmental Authority shall have any right to request any return or reimbursement of funds from the Lenders in connection with monies received under the Credit Documents. Without limiting the generality of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the liability of Airgas hereunder which shall remain absolute and unconditional as described above:

(a) at any time or from time to time, without notice to Airgas, the time for any performance of or compliance with any of the Obligations shall be extended, or such performance or compliance shall be waived;

(b) any of the acts mentioned in any of the provisions of any of the Credit Documents or any other agreement or instrument referred to in the Credit Documents shall be done or omitted;

(c) the maturity of any of the Obligations shall be accelerated, or any of the Obligations shall be modified, supplemented or amended in any respect, or any right under any of the Credit Documents, or any other agreement or instrument referred to in the Credit Documents shall be waived or any other guarantee of any of the Obligations or any applicable security therefor shall be released, impaired or exchanged in whole or in part or otherwise dealt with;

(d) any Lien granted to, or in favor of, the Agent or any Lender or Lenders as security for any of the Obligations shall fail to attach or be perfected; or

(e) any of the Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of Airgas) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of Airgas).

With respect to its obligations hereunder, Airgas hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Agent or any Lender exhaust any right, power or remedy or proceed against any Person under any of the Credit Documents or any other agreement or instrument referred to in the Credit Documents, or against any other Person under any other guarantee of, or security for, any of the Foreign Obligations. The rights of the Agent and the Lenders and the Affiliates of any of the Lenders contained herein shall be in addition to and independent of all other rights which they may at any time have or hold in respect of any of the Foreign Obligations.

12.3 Reinstatement.

The obligations of Airgas under this Article XII shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Foreign Obligations is rescinded or must be otherwise restored by any holder of any of the Foreign Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and Airgas agrees that it will indemnify the Agent and each Lender on demand for all reasonable costs and expenses (including, without limitation, fees and expenses of counsel) incurred by the Agent or such Lender in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

12.4 Certain Additional Waivers.

Airgas agrees that it shall have no right of recourse to security for the Foreign Obligations except through the exercise of the rights of subrogation pursuant to Section 12.2.

12.5 Remedies.

Airgas agrees that, to the fullest extent permitted by law, as between Airgas, on the one hand, and the Agent and the Lenders, on the other hand, the Foreign Obligations may be declared to be forthwith due and payable as provided in Section 9.2 (and shall be deemed to have become automatically due and payable in the circumstances provided in said Section 9.2) for purposes of Section 12.1 notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Foreign Obligations being deemed to have become automatically due and payable), the Foreign Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by Airgas for purposes of Section 12.1.

12.6 Guarantee of Payment; Continuing Guarantee.

The guarantee in this Article XII is a guaranty of payment and not of collection, is a continuing guarantee, and shall apply to all Foreign Obligations whenever arising.

Schedule 1.1B

MANDATORY COST FORMULAE

1.	The Mandatory Cost (to the extent applicable) is an addition to the interest rate to compensate Lenders for the cost of compliance with:

(a)

the requirements of the Bank of England and/or the Financial Services Authority (“FSA”) (or, in either case, any other authority which replaces all or any of its functions); or

(b)

the requirements of the European Central Bank.

On the first day of each Interest Period (or as soon as practicable thereafter) the Agent shall calculate, as a percentage rate, a rate (the “Additional Cost Rate”) for each Lender, in accordance with the paragraphs set out below. The Mandatory Cost will be calculated by the Agent as a weighted average of the Lenders’ Additional Cost Rates (weighted in proportion to the percentage participation of each Lender in the relevant Loan) and will be expressed as a percentage rate per annum. The Agent will, at the request of Airgas or any Lender, deliver to Airgas or such Lender, as the case may be, a statement setting forth the calculation of any Mandatory Cost.

The Additional Cost Rate for any Lender lending from a lending office in a Participating Member State will be the percentage notified by that Lender to the Agent. This percentage will be certified by such Lender in its notice to the Agent as the cost (expressed as a percentage of such Lender’s participation in all Loans made from such lending office) of complying with the minimum reserve requirements of the European Central Bank in respect of Loans made from that lending office.

4.	The Additional Cost Rate for any Lender lending from a lending office in the United Kingdom will be calculated by the Agent as follows:

(a)

in relation to any Loan in Sterling:


		AB+C(B-D)+E × 0.01		per cent per annum
		100 - (A+C)		per cent per annum

(b)

in relation to any Loan in any currency other than Sterling:


		E × 0.01		per cent per annum
		300		per cent per annum

Where:

“A”	is the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash ratio deposit with the Bank of England to comply with cash ratio requirements.

“B”

is the percentage rate of interest (excluding the Applicable Rate, the Mandatory Cost and any interest charged on overdue amounts pursuant to Section 4.1 and, in the case of interest (other than on overdue amounts) charged at the default rate of interest specified in the Credit Agreement, without counting any increase in interest rate effected by the charging of such default interest rate) payable for the relevant Interest Period of such Loan.

“C”	is the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.

“D”	is the percentage rate per annum payable by the Bank of England to the Agent on interest bearing Special Deposits.

“E”	is designed to compensate Lenders for amounts payable under the Fees Regulations and is calculated by the Agent as being the average of the most recent rates of charge supplied by the Lenders to the Agent pursuant to paragraph 7 below and expressed in pounds per £1,000,000.

5.	For the purposes of this Schedule:

(a)

“Eligible Liabilities” and “Special Deposits” have the meanings given to them from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of England;

(b)

“Fees Regulations” means the FSA Supervision Manual or such other law or regulation as may be in force from time to time in respect of the payment of fees for the acceptance of deposits;

(c)

“Fee Tariffs” means the fee tariffs specified in the Fees Regulations under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fees Regulations but taking into account any applicable discount rate); and

(d)

“Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Regulations.

In application of the above formulae, A, B, C and D will be included in the formulae as percentages (i.e. 5% will be included in the formula as 5 and not as 0.05). A negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places.

If requested by the Agent or Airgas, each Lender with a lending office in the United Kingdom or a Participating Member State shall, as soon as practicable after publication by the FSA, supply to the Agent and Airgas, the rate of charge payable by such Lender to the FSA pursuant to the Fees Regulations in respect of the relevant financial year of the FSA (calculated for this purpose by such Lender as being the average of the Fee Tariffs applicable to such Lender for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of such Lender.

8.	Each Lender shall supply any information required by the Agent or Airgas for the purpose of calculating its Additional Cost Rate. In particular, but without limitation, each Lender shall supply the following information in writing on or prior to the date on which it becomes a Lender:

(a)

its jurisdiction of incorporation and the jurisdiction of the lending office out of which it is making available its participation in the relevant Loan; and

(b)

any other information that the Agent or Airgas may reasonably require for such purpose.

Each Lender shall promptly notify the Agent and Airgas in writing of any change to the information provided by it pursuant to this paragraph.

The percentages or rates of charge of each Lender for the purpose of A, C and E above shall be determined by the Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless a Lender notifies the Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits, Special Deposits and the Fees Regulations are the same as those of a typical bank from its jurisdiction of incorporation with a lending office in the same jurisdiction as such Lender’s lending office.
