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. Lenders make a Revolving U.S. Loan in the amount of the drawing as provided in subsection (e) hereof 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 of drawing under any U.S. Letter of Credit (either with the proceeds of a Revolving U.S. Loan obtained hereunder or otherwise) in same day funds. 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 U.S. Base Rate plus the sum of (i) the Applicable Percentage and (ii) two percent (2%). 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 U.S. Agent, the U.S. Lenders, the beneficiary of the U.S. Letter of Credit drawn upon or any other Person, including without limitation any defense based on any failure of Airgas to receive consideration or the legality, validity, regularity or unenforceability of the U.S. Letter of Credit. The U.S. Issuing Lender will promptly notify the other U.S. Lenders of the amount of any unreimbursed drawing under any U.S. Letter of Credit and each U.S. Lender shall promptly pay to the U.S. 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. Lender's pro rata share of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such U.S. Lender from the U.S. Issuing Lender if such notice is received at or before 2:00 P.M. (Charlotte, North Carolina time) otherwise such payment shall be made at or before 12:00 NOON (Charlotte, North Carolina time) on the Business Day next succeeding the day such notice is received. If such U.S. Lender does not pay such amount to the U.S. Issuing Lender in full upon such request, such U.S. Lender shall, on demand, pay to the U.S. 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. 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. 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. 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 EX-31 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. Lender to the U.S. Issuing Lender, such U.S. Lender shall, automatically and without any further action on the part of the U.S. Issuing Lender or such U.S. 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. (e) Repayment with Revolving U.S. Loans. On any day on which Airgas shall have requested, or shall be deemed to have requested, a Revolving U.S. Loan advance to reimburse a drawing under a U.S. Letter of Credit, the U.S. Agent shall give notice to the U.S. Lenders that a Revolving U.S. 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 Revolving U.S. Loan advance comprised of U.S. Base Rate Loans (or Eurodollar 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. Lenders (notwithstanding any termination of the Commitments pursuant to Section 9.2) pro rata based on the respective U.S. Commitment Percentages of the U.S. Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 9.2) and the proceeds thereof shall be paid directly to the U.S. Issuing Lender for application to the respective U.S. LOC Obligations. Each such U.S. Lender hereby irrevocably agrees to make its pro rata share of each such Revolving U.S. 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 Revolving U.S. 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 Revolving U.S. Loan to be made by the time otherwise required hereunder, (v) whether the date of such borrowing is a date on which Revolving U.S. 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 Revolving U.S. 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 such U.S. 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 such participation in the outstanding U.S. LOC Obligations as shall be necessary to cause each such U.S. Lender to share in such U.S. LOC Obligations ratably (based upon the respective U.S. Commitment Percentages of the U.S. Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 9.2)), provided that at the time any purchase of participation pursuant to this sentence is actually made, the purchasing U.S. Lender shall be required to pay to the U.S. Issuing Lender, to the extent not paid to the Issuer by Airgas in accordance with the terms of subsection (d) hereof, 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 Revolving U.S. Loan advance, the Federal Funds Rate, and thereafter at a rate equal to the U.S. Base Rate. EX-32 (f) Designation of Subsidiaries as Account Parties. Notwithstanding anything to the contrary set forth in this Credit Agreement, including without limitation Section 2.3(a) hereof, 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. (g) 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. (h) Uniform Customs and Practices. The U.S. Issuing Lender may have the U.S. Letters of Credit be subject to The Uniform Customs and Practice for Documentary Credits, as published as of the date of issue by the International Chamber of Commerce (the "UCP"), in which case the UCP may be incorporated therein and deemed in all respects to be a part thereof. (i) 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. Lender, the U.S. 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 the Indemnitees 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 any 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 Government Acts or any other cause beyond the control of the U.S. Issuing Lender. (iv) Nothing in this subsection (i) is intended to limit the reimbursement obligations of Airgas contained in subsection (d) above. The obligations of Airgas under this subsection (i) 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 subsection (i), 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 EX-33 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. (j) 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. 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 2.3 shall be deemed to prejudice the right of any U.S. Lender to recover from the U.S. Issuing Lender any amounts made available by such U.S. Lender to the U.S. Issuing Lender pursuant to this Section 2.3 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. (k) 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. 2.4 U.S. Swingline Loan Subfacility.

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 2.4, and may be repaid and reborrowed in accordance with the provisions hereof.

The U.S. Swingline Lender shall credit the funds requested to an Airgas account maintained with the Swingline Lender by 3:00 P.M. (Charlotte, North Carolina time) on the Business Day of the requested borrowing. EX-34 (ii) Minimum Amounts. Each U.S. Swingline Loan advance shall be in a minimum principal amount of U.S.$100,000 and in integral multiples thereof (or the remaining amount of the U.S. Swingline Committed Amount, if less).

The principal amount of all U.S. Swingline Loans shall be due and payable 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 Termination Date. The U.S. Swingline Lender may, at any time, in its sole discretion, by written notice to Airgas and the U.S. Lenders, demand repayment of its U.S. Swingline Loans by way of a Revolving U.S. Loan advance, in which case Airgas shall be deemed to have requested a Revolving U.S. 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 shall be deemed to have been given one Business Day prior to the Termination 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 indebtedness hereunder and the exercise of remedies in accordance with the provisions of Section 9.2. Each U.S. Lender hereby irrevocably agrees to make its pro rata share of each such Revolving U.S. 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 Revolving U.S. 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 Revolving U.S. Loan to be made by the time otherwise required hereunder, (V) whether the date of such borrowing is a date on which Revolving U.S. 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 Revolving U.S. 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. 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 such U.S. Lender to share in such U.S. Swingline Loans ratably based upon its U.S. Commitment Percentage of the Revolving U.S. Committed Amount (determined before giving effect to any termination of the Commitments pursuant to Section 4.4), 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. 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 subsection (c)(ii) hereof, 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 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. Interest on U.S. Swingline Loans shall be payable in arrears on each applicable Interest Payment Date (or at such other times as may be specified herein). (d) U.S. Swingline Note.

For purposes hereof, Eurodollar Loans with different Interest Periods shall be considered as separate Eurodollar 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 Eurodollar Loan with a single Interest Period. 364-Day Revolving Loans hereunder (other than any 364-Day Revolving Loans which have been converted to term loans pursuant to Section 2.5(f)) may be repaid and reborrowed in accordance with the provisions hereof.

If Airgas shall fail to specify in any such Notice of Borrowing (I) an applicable Interest Period in the case of a Eurodollar Loan, then such notice shall be deemed to be a request for an Interest Period of one month, or (II) the type of 364-Day Revolving Loan requested, then such notice shall be deemed to be a request for a U.S. Base Rate Loan hereunder. The U.S. Agent shall give notice to each affected U.S. Lender promptly upon receipt of each Notice of Borrowing pursuant to this Section 2.5(b)(i), specifying the contents thereof and each such U.S. Lender's share of any borrowing to be made pursuant thereto. (ii) Minimum Amounts. Each Eurodollar Loan or U.S. Base Rate Loan that is a 364-Day Revolving Loan shall be in a minimum aggregate principal amount of U.S.$5,000,000 and integral multiples of U.S.$1,000,000 in excess thereof (or the remaining amount of the 364-Day Revolving Committed Amount, if less).

In the event that any U.S. Lender chooses to extend the Termination Date for such a 364-day period, notice shall be given by the U.S. Agent to Airgas no more than 30 nor less than 25 days prior to the then effective Termination Date. The principal amounts of all outstanding 364-Day Revolving Loans representing 364-Day Revolving Commitments of U.S. Lenders not extending their respective Commitments pursuant to this Section 2.5(f) shall convert into term loans which shall be due and payable in accordance with Section 2.5(c).

(Toronto, Canada time) on the Business Day of the requested borrowing) or (ii) by way of overdraft in the Canadian Dollar operating accounts maintained by such Canadian Borrower with the Canadian Swingline Lender (collectively, the "Operating Accounts"), for the purposes EX-39 hereinafter set forth; provided, however, (A) the aggregate principal amount of Canadian Swingline Loans outstanding at any time shall not exceed FIVE MILLION CANADIAN DOLLARS (C$5,000,000) (the "Canadian Swingline Committed Amount"), and (B) the aggregate principal amount of outstanding Revolving Canadian Loans plus the aggregate principal amount of outstanding Canadian Swingline Loans plus Canadian LOC Obligations outstanding plus the BA Outstandings shall not exceed the Revolving Canadian Committed Amount. Unless the Canadian Borrowers have made prior arrangements with the Canadian Swingline Lender (including without limitation by requesting a Revolving Canadian Loan), the Canadian Swingline Lender may return any debit from an Operating Account that, if paid, would result in the aggregate principal amount of outstanding Canadian Swingline Loans exceeding the Canadian Swingline Committed Amount if (1) any Default or Event of Default then exists or (2) if the applicable Canadian Borrower does not, on or before the first Business Day after receipt by such Canadian Borrower of notice of such excess from the Canadian Swingline Lender, deposit money or request a Revolving Canadian Loan sufficient to cover such debit. Canadian Swingline Loans hereunder may be repaid and reborrowed in accordance with the provisions hereof. (b) Repayment of Canadian Swingline Loans. Each Canadian Borrower hereby promises to repay the principal amount of each Canadian Swingline Loan taken by such Canadian Borrower on the earlier of (A) the maturity date agreed to by the Canadian Swingline Lender and such Canadian Borrower with respect to such Canadian Swingline Loan or (B) the Termination Date. The Canadian Swingline Lender may, at any time, in its sole discretion, by written notice to the Canadian Borrower and the Canadian Lenders, demand repayment of its Canadian Swingline Loans by way of a Revolving Canadian Loan advance, in which case the Canadian Borrower shall be deemed to have requested a Revolving Canadian Loan advance in the amount of such Canadian Swingline Loans; provided, however, that such a demand shall be deemed to have been given one Business Day prior to the Termination 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 indebtedness hereunder and the exercise of remedies in accordance with the provisions of Section 9.2. Each Canadian Lender hereby irrevocably agrees to make its pro rata share of each such Revolving Canadian 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 Revolving Canadian 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 Revolving Canadian Loan to be made by the time otherwise required hereunder, (V) whether the date of such borrowing is a date on which Revolving Canadian 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. (c) Interest on Canadian Swingline Loans. (i) Interest Rate. Subject to the provisions of Section 4.1, each Canadian Swingline Loan shall bear interest at a per annum rate (computed on the basis of the actual number of days elapsed over a year of 365 days) equal to the Canadian Base Rate; and (ii) Payment of Interest. With respect to each Canadian Swingline Loan taken by a Canadian Borrower, such Canadian Borrower hereby promises to pay all interest on the outstanding principal amount of such Canadian Swingline Loan in arrears on each applicable Interest Payment Date (or at such other times as may be specified herein). EX-40 3.3 Canadian Letter of Credit Subfacility. (a) Issuance. Subject to the terms and conditions hereof and of the Canadian LOC Documents, if any, and any other terms and conditions which the Canadian Issuing Lender may reasonably require, the Canadian Lenders will participate in the issuance by the Canadian Issuing Lender from time to time of such Canadian Letters of Credit in Canadian Dollars from the Closing Date until the Termination Date as a Canadian Borrower may request, in a form acceptable to the Canadian Issuing Lender; provided, however, that (i) the Canadian LOC Obligations outstanding shall not at any time exceed FIFTY MILLION CANADIAN DOLLARS (C$50,000,000) (the "Canadian LOC Committed Amount") and (ii) the sum of the aggregate principal amount of outstanding Canadian Revolving Loans plus the aggregate principal amount of outstanding Canadian Swingline Loans plus Canadian LOC Obligations outstanding plus BA Outstandings shall not at any time exceed the aggregate Revolving Canadian Committed Amount. No Canadian Letter of Credit shall (x) have an original expiry date more than one year from the date of issuance or (y) as originally issued or as extended, have an expiry date extending beyond the Termination Date. Each Canadian Letter of Credit shall comply with the related Canadian LOC Documents. The issuance and expiry date of each Canadian Letter of Credit shall be a Business Day. (b) Notice and Reports. The request for the issuance of a Canadian Letter of Credit shall be submitted by the applicable Canadian Borrower (by its duly authorized officers or representatives) to the Canadian Issuing Lender at least three (3) Business Days prior to the requested date of issuance. The Canadian Issuing Lender will, at least quarterly and more frequently upon request, disseminate to each of the Canadian Lenders a detailed report specifying the Canadian 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 and expiry date as well as any payments or expirations which may have occurred. (c) Participation. Each Canadian Lender, upon issuance of a Canadian Letter of Credit (or, in the case of each Existing Canadian Letter of Credit, on the Closing Date), shall be deemed to have purchased without recourse a risk participation from the Canadian Issuing Lender in such Canadian Letter of Credit and the obligations arising thereunder, in each case in an amount equal to its pro rata share of the obligations under such Canadian Letter of Credit (based on the respective Canadian Commitment Percentages of the Canadian Lenders) and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the Canadian Issuing Lender therefor and discharge when due, its pro rata share of the obligations arising under such Canadian Letter of Credit. Without limiting the scope and nature of each Canadian Lender's participation in any Canadian Letter of Credit, to the extent that the Canadian Issuing Lender has not been reimbursed as required hereunder or under any such Canadian Letter of Credit, each such Canadian Lender shall pay to the Canadian Issuing Lender its pro rata share of such unreimbursed drawing pursuant to the provisions of subsection (d) hereof. The obligation of each Canadian Lender to so reimburse the Canadian 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 each Canadian Borrower to reimburse the Canadian Issuing Lender under any Canadian Letter of Credit issued for the account of such Canadian Borrower, together with interest as hereinafter provided. (d) Reimbursement. In the event of any drawing under any Canadian Letter of Credit, the Canadian Issuing Lender will promptly notify the applicable Canadian Borrower. Unless the applicable Canadian Borrower shall EX-41 immediately notify the Canadian Issuing Lender that such Canadian Borrower intends to otherwise reimburse the Canadian Issuing Lender for such drawing, such Canadian Borrower shall be deemed to have requested that the Canadian Lenders make a Revolving Canadian Loan in the amount of the drawing as provided in subsection (e) hereof on the related Canadian Letter of Credit, the proceeds of which will be used to satisfy the related reimbursement obligations. Each Canadian Borrower promises to reimburse the Canadian Issuing Lender on the day of drawing under any Canadian Letter of Credit issued for the account of such Canadian Borrower (either with the proceeds of a Revolving Canadian Loan obtained hereunder or otherwise) in same day funds. If the applicable Canadian Borrower shall fail to reimburse the Canadian Issuing Lender (either with the proceeds of a Revolving Canadian Loan obtained hereunder or otherwise), the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Canadian Base Rate plus two percent (2%). The reimbursement obligations of each Canadian Borrower hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of setoff, counterclaim or defense to payment such Canadian Borrower may claim or have against the Canadian Issuing Lender, the U.S. Agent, the Canadian Agent, the Canadian Lenders, the beneficiary of the Canadian Letter of Credit drawn upon or any other Person, including without limitation any defense based on any failure of such Canadian Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Canadian Letter of Credit. The Canadian Issuing Lender will promptly notify the other Canadian Lenders of the amount of any unreimbursed drawing under any Canadian Letter of Credit and each Canadian Lender shall promptly pay to the Canadian Agent for the account of the Canadian Issuing Lender in Canadian Dollars and in immediately available funds, the amount of such Canadian Lender's pro rata share of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Canadian Lender from the Canadian Issuing Lender if such notice is received at or before 2:00 P.M. (Toronto, Canada time) otherwise such payment shall be made at or before 12:00 NOON (Toronto, Canada time) on the Business Day next succeeding the day such notice is received. If such Canadian Lender does not pay such amount to the Canadian Issuing Lender in full upon such request, such Canadian Lender shall, on demand, pay to the Canadian Agent for the account of the Canadian Issuing Lender interest on the unpaid amount during the period from the date of such drawing until such Canadian Lender pays such amount to the Canadian Issuing Lender in full at a rate per annum equal to the Canadian Base Rate. Each Canadian Lender's obligation to make such payment to the Canadian Issuing Lender, and the right of the Canadian 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 Canadian Lender to the Canadian Issuing Lender, such Canadian Lender shall, automatically and without any further action on the part of the Canadian Issuing Lender or such Canadian Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the Canadian Issuing Lender) in the related unreimbursed drawn portion of the Canadian LOC Obligation and in the interest thereon and in the related Canadian LOC Documents, and shall have a claim against the Canadian Borrower with respect thereto. (e) Repayment with Revolving Canadian Loans. On any day on which a Canadian Borrower shall have requested, or shall be deemed to have requested, a Revolving Canadian Loan advance to reimburse a drawing under a Canadian Letter of Credit, the Canadian Agent shall give notice to the Canadian Lenders that a Revolving Canadian Loan advance has been requested or deemed requested by such Canadian Borrower to be made in connection with a drawing under a EX-42 Canadian Letter of Credit, in which case a Revolving Canadian Loan shall be immediately made to such Canadian Borrower by all Canadian Lenders (notwithstanding any termination of the Commitments pursuant to Section 9.2) pro rata based on the respective Canadian Commitment Percentages of the Canadian Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 9.2) and the proceeds thereof shall be paid directly to the Canadian Issuing Lender for application to the respective Canadian LOC Obligations. Each such Canadian Lender hereby irrevocably agrees to make its pro rata share of each such Revolving Canadian 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 Revolving Canadian 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) that any such request or deemed request for Revolving Canadian Loan is not made by the time otherwise required hereunder, (v) whether the date of such borrowing is a date on which Revolving Canadian 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 Revolving Canadian 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 a Canadian Borrower or Airgas), then each such Canadian 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 any Canadian Borrower on or after such date and prior to such purchase) from the Canadian Issuing Lender such participation in the outstanding Canadian LOC Obligations as shall be necessary to cause each such Canadian Lender to share in such Canadian LOC Obligations ratably (based upon the respective Canadian Commitment Percentages of the Canadian Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 9.2)), provided that at the time any purchase of participation pursuant to this sentence is actually made, the purchasing Canadian Lender shall be required to pay to the Canadian Issuing Lender, to the extent not paid to the Issuer by Airgas in accordance with the terms of subsection (d) hereof, 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 a rate equal to the Canadian Base Rate. (f) Renewal, Extension. The renewal or extension of any Canadian Letter of Credit shall, for purposes hereof, be treated in all respects the same as the issuance of a new Canadian Letter of Credit hereunder. (g) Uniform Customs and Practices. The Canadian Issuing Lender may have the Canadian Letters of Credit be subject to The Uniform Customs and Practice for Documentary Credits, as published as of the date of issue by the International Chamber of Commerce (the "UCP"), in which case the UCP shall be expressly incorporated therein and deemed in all respects to be a part thereof. (h) Indemnification; Nature of Canadian Issuing Lender's Duties. (i) Each Canadian Borrower agrees to indemnify and hold harmless the Canadian Issuing Lender, each other Canadian Lender, the Canadian Agent, the U.S. 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 Canadian Letter of Credit issued for the account of such EX-43 Canadian Borrower; provided that the Canadian Borrowers shall not be required to indemnify the Indemnitees 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 any Indemnitee in determining whether a request presented under any Canadian Letter of Credit complied with the terms of such Canadian Letter of Credit or (B) caused by the Canadian Issuing Lender's failure to pay under any Canadian Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Canadian Letter of Credit (unless such payment is prohibited by any law, regulation, court order or decree). (ii) Each Canadian Borrower agrees, as between such Canadian Borrower and the Canadian Issuing Lender, such Canadian Borrower shall assume all risks of the acts, omissions or misuse by the beneficiary of any Canadian Letter of Credit issued for the account of such Canadian Borrower. (iii) The Canadian Issuing Lender shall not, in any way, be liable for any failure by the Canadian Issuing Lender or anyone else to pay any drawing under any Canadian Letter of Credit as a result of any action by any Governmental Authority or any other cause beyond the control of the Canadian Issuing Lender. (iv) Nothing in this subsection (h) is intended to limit the reimbursement obligations of the Canadian Borrowers contained in subsection (d) above. The obligations of the Canadian Borrowers under this subsection (h) shall survive the termination of this Credit Agreement. No acts or omissions of any current or prior beneficiary of a Canadian Letter of Credit shall in any way affect or impair the rights of the Canadian Issuing Lender to enforce any right, power or benefit under this Credit Agreement. (v) Notwithstanding anything to the contrary contained in this subsection (h), the Canadian Borrowers shall have no obligation to indemnify the Canadian Issuing Lender in respect of any liability incurred by the Canadian Issuing Lender (A) arising out of the gross negligence or willful misconduct of the Canadian Issuing Lender, or (B) caused by the Canadian Issuing Lender's failure to pay under any Canadian Letter of Credit after presentation to it of a request strictly complying with the terms and conditions of such Canadian Letter of Credit, as determined by a court of competent jurisdiction, unless such payment is prohibited by any law, regulation, court order or decree. (i) Responsibility of Canadian Issuing Lender. It is expressly understood and agreed that the obligations of the Canadian Issuing Lender hereunder to the Canadian Lenders are only those expressly set forth in this Credit Agreement and that the Canadian 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 3.3 shall be deemed to prejudice the right of any Canadian Lender to recover from the Canadian Issuing Lender any amounts made available by such Canadian Lender to the Canadian Issuing Lender pursuant to this Section 3.3 in the event that it is determined by a court of competent jurisdiction that the payment with respect to a Canadian Letter of Credit constituted gross negligence or willful misconduct on the part of the Canadian Issuing Lender. (j) Conflict with Canadian LOC Documents. In the event of any conflict between this Credit Agreement and any Canadian LOC Document (including any letter of credit application), this Credit Agreement shall control. EX-44 3.4 Bankers' Acceptances. (a) Issuance. Subject to the terms and conditions hereof and any other terms and conditions which a Canadian Lender may reasonably require (so long as such terms and conditions do not impose any financial obligation on or require any Lien (not otherwise contemplated by this Credit Agreement) to be given by any Consolidated Party or conflict with any obligation of, or detract from any action which may be taken by, any Canadian Borrower under this Credit Agreement), each Canadian Lender agrees, severally and not jointly, at any time and from time to time from the Closing Date to the Termination Date, to create Bankers' Acceptances by accepting drafts of a Canadian Borrower presented to it for acceptance in an amount equal to such Canadian Lender's Commitment Percentage of such Bankers' Acceptances as a Canadian Borrower may request on such date; provided, however, that the aggregate amount of Revolving Canadian Loans outstanding plus the aggregate principal amount of outstanding Canadian Swingline Loans plus Canadian LOC Obligations outstanding plus the BA Outstandings may not exceed the Revolving Canadian Committed Amount. Upon the acceptance of any draft of a Canadian Borrower pursuant hereto, such Canadian Borrower shall pay to the Canadian Lender accepting the same, in advance, the Acceptance Fee. Forthwith after each request for drawdown of, continuation of or conversion into Banker's Acceptances, the Canadian Agent shall notify each Canadian Lender of the amount and denomination of the Bankers' Acceptances to be accepted by such Canadian Lender. Canadian Borrower shall as soon as practical deliver to the Canadian Agent a notice confirming the issuance of Bankers' Acceptances drawn by it and specifying the net proceeds derived therefrom. For greater certainty, with respect to each extension of credit by way of Bankers' Acceptances from the Canadian Lenders, each Bankers' Acceptance shall have the same term. (b) General Provisions regarding Bankers' Acceptances. (i) Any draft tendered by a Canadian Borrower for acceptance by a Canadian Lender shall be payable in Canada, shall be in the standard form of bankers' acceptance accepted by such Canadian Lender and shall have a term ending on a Business Day not less than 30 days (or any earlier date, subject to availability) or more than 180 days from the date of acceptance. Each extension of credit by way of Bankers' Acceptances from the Canadian Lenders shall be for the minimum aggregate principal amount of C$1,500,000 and in multiples of C$100,000. (ii) On presentation of a draft for acceptance the applicable Canadian Borrower shall pay to the applicable Canadian Lender a stamping fee calculated on the principal amount and for the term of the draft equal to the Applicable Percentage. (iii) All Bankers' Acceptances to be accepted by the Canadian Lenders shall be obtained through the Canadian Agent. Each Canadian Lender agrees to purchase at the Discount Rate each Bankers' Acceptance accepted by it and to provide to the Canadian Agent for the account of the applicable Canadian Borrower the discount proceeds less the stamping fee. A Canadian Lender may hold, sell, rediscount or otherwise dispose of any or all Bankers' Acceptances accepted and purchased by it. (iv) The applicable Canadian Borrower shall provide for each of the Bankers' Acceptances at their respective maturities at the Canadian Agent's main branch in Toronto, Canada (either with the proceeds of a Revolving Canadian Loan obtained hereunder or otherwise). The Canadian Borrowers will continue to be required to provide as aforesaid for each of the Bankers' Acceptances at maturity notwithstanding the fact that the applicable Canadian Lender may be the holder of a Bankers' Acceptance previously issued EX-45 by that Canadian Lender. Any amount owing in respect of any Bankers' Acceptance which is not paid in accordance with the foregoing shall be subject to the same terms as are applicable to Canadian Base Rate Loans, but be payable on demand. (v) In the event that demand is made on the Canadian Borrowers pursuant to Section 9.2, the Canadian Borrowers who have then outstanding any Bankers' Acceptance(s) shall forthwith pay to the Canadian Lenders an amount equal to each such Canadian Lender's maximum potential liability under outstanding Bankers' Acceptances stamped by it on behalf of the applicable Canadian Borrower. Such amount shall be held by the Canadian Lenders for set-off against future indebtedness owing by the applicable Canadian Borrower to the Canadian Lenders in respect of such Bankers' Acceptance(s). (vi) Each Canadian Borrower shall supply the Canadian Lenders with such number of drafts executed and endorsed on behalf of such Canadian Borrower (by its duly authorized officers or other representatives) (or by duly authorized officers or other representatives of Airgas) as the Canadian Lenders may from time to time reasonably request. The signatures of such officers may be mechanically reproduced in facsimile and such facsimile signatures shall be valid and binding on such Canadian Borrower as if they had been manually signed by such officers. Notwithstanding that any of the individuals whose manual or facsimile signature appears on any draft may no longer hold office at the date thereof or at the date of its acceptance by a Canadian Lender hereunder or at any time thereafter, any draft or Bankers' Acceptance signed as provided for in this Section 3.4 shall be valid and binding on the applicable Canadian Borrower. The Canadian Lenders will not be liable for their failure to accept drafts pursuant to this Credit Agreement if such failure is, in whole or in part, due to the failure of a Canadian Borrower to provide drafts to a Canadian Lender in accordance with this Section 3.4. The responsibility of a Canadian Lender in respect of the safekeeping of executed drafts which are delivered to it for acceptance hereunder shall be limited to the exercise of the same degree of care which such Canadian Lender gives to its own property, provided that such Canadian Lender shall not be deemed to be an insurer thereof. Each of the Canadian Borrowers hereby confirms each of the Canadian Lenders shall be entitled to rely upon instructions provided by Airgas regarding the completion of drafts which are delivered to it for acceptance on behalf of any Canadian Borrower hereunder. (vii) Each Canadian Borrower shall ensure that no Bankers' Acceptance it draws has a maturity date beyond the Termination Date. 3.5 Guaranty of Canadian Borrowers' Obligations. (a) Guaranty. The Guarantor hereby guarantees to each Lender and the Agents as hereinafter provided, as primary obligor and not as surety, the prompt payment of the Canadian Borrowers' 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. The Guarantor hereby further agrees that if any of the Canadian Borrowers' 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), the Guarantor 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 Canadian Borrowers' 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. EX-46 (b) Obligations Unconditional. The obligations of the Guarantor under Section 3.5(a) 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 Canadian Borrower 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 3.5(b) that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances. The Guarantor agrees that it shall have no right of subrogation, indemnity, reimbursement or contribution against any Canadian Borrower or any other guarantor of the Canadian Borrower Obligations for amounts paid under this Section 3.5 until such time as the Lenders have been paid in full, 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 the Guarantor hereunder which shall remain absolute and unconditional as described above: (i) at any time or from time to time, without notice to the Guarantor, the time for any performance of or compliance with any of the Canadian Borrowers' Obligations shall be extended, or such performance or compliance shall be waived; (ii) 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; (iii) the maturity of any of the Canadian Borrower Obligations shall be accelerated, or any of the Canadian Borrower 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 Canadian Borrower Obligations or any security therefor shall be released, impaired or exchanged in whole or in part or otherwise dealt with; (iv) any of the Canadian Borrowers' Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of the Guarantor) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of the Guarantor). With respect to its obligations hereunder, the Guarantor 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 Canadian Borrowers' Obligations. (c) Reinstatement. The obligations of the Guarantor under this Section 3.5 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 Canadian Borrowers' Obligations is rescinded or must be otherwise restored by any holder of any of the Canadian Borrowers' Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and the EX-47 Guarantor agrees that it will indemnify the Canadian Agent and each Canadian Lender on demand for all reasonable costs and expenses (including, without limitation, fees and expenses of counsel) incurred by the Canadian Agent or such Canadian 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. (d) Certain Additional Waivers. Without limiting the generality of the provisions of this Section 3.5, the Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. Sections 26-7 through 26-9, inclusive, to the extent applicable. The Guarantor further agrees that it shall have no right of recourse to security for the Canadian Borrowers' Obligations, except through the exercise of the rights of subrogation pursuant to Section 3.5(b). (e) Remedies. The Guarantor agrees that, to the fullest extent permitted by law, as between the Guarantor, on the one hand, and the Canadian Agent and the Canadian Lenders, on the other hand, the Canadian Borrowers' 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 3.5(a) notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Canadian Borrowers' Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Canadian Borrowers' Obligations being deemed to have become automatically due and payable), the Canadian Borrowers' Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by the Guarantor for purposes of Section 3.5(a). (f) Guarantee of Payment; Continuing Guarantee. The guarantee in this Section 3.5 is a guaranty of payment and not of collection, is a continuing guarantee, and shall apply to all Canadian Borrowers' Obligations whenever arising. 3.6 Reset Mechanism. Each Canadian Lender agrees that it will, at any time or from time to time, upon the request of the Canadian Agent, purchase portions of the outstanding Revolving Canadian Loans, Canadian Swingline Loans, Canadian LOC Obligations and BA Outstandings made available by the other Canadian Lenders hereunder and make any other adjustments which may be necessary or appropriate, in order that the amount of such outstanding Revolving Canadian Loans, Canadian Swingline Loans, Canadian LOC Obligations and BA Outstandings made available by the respective Canadian Lenders, as adjusted pursuant to this Section 3.6, will be in the same proportions as the amount which each Canadian Lender's Canadian Commitment Percentage bears to the total Canadian Commitment Percentages of all the Canadian Lenders. SECTION 4 OTHER PROVISIONS RELATING TO CREDIT FACILITIES 4.1 Default Rate. Upon the occurrence, and during the continuance, of an Event of Default, 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 bear interest, payable on demand, at a per annum rate 2% greater than EX-48 the rate which would otherwise be applicable (or if no rate is applicable, whether in respect of interest, fees or other amounts, then 2% greater than the U.S. Base Rate). 4.2 Extension and Conversion. (a) Airgas. Subject to the terms of Section 5.2, Airgas shall have the option, on any Business Day, to extend existing Revolving U.S Loans or 364-Day Revolving Loans into a subsequent permissible Interest Period or to convert any such Loans into Loans of another interest rate type; provided, however, that (i) except as provided in Section 4.8, Eurodollar Loans may be converted into U.S. Base Rate Loans only on the last day of the Interest Period applicable thereto, (ii) Eurodollar Loans may be extended, and U.S. Base Rate Loans may be converted into Eurodollar Loans, only if no Default or Event of Default is in existence on the date of extension or conversion, (iii) Loans extended as, or converted into, Eurodollar 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 Sections 2.1(b)(ii), 2.5(b)(ii) and 3.1(b)(ii), (iv) no more than 11 Eurodollar Loans shall be outstanding hereunder at any time (it being understood that, for purposes hereof, Eurodollar Loans with different Interest Periods shall be considered as separate Eurodollar 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 Eurodollar Loan with a single Interest Period), (v) any request for extension or conversion of a Eurodollar Loan which shall fail to specify an Interest Period shall be deemed to be a request for an Interest Period of one month and (vi) Competitive U.S. Loans and 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 U.S. Agent prior to 11:00 A.M. (Charlotte, North Carolina time) on the Business Day of, in the case of the conversion of a Eurodollar Loan into a U.S. Base Rate Loan, and on the third Business Day prior to, in the case of the extension of a Eurodollar Loan as, or conversion of a U.S. Base Rate Loan into, a Eurodollar 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. Each request for extension or conversion shall be irrevocable and shall constitute a representation and warranty by Airgas of the matters specified in subsections (ii), (iii), (iv) and (v) of Section 5.2.

If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, Airgas 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 date hereof, 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 EX-56 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 Canadian Letter of Credit, any Eurodollar Loans, Competitive U.S. Loans made by it, any Bankers' Acceptances accepted by it, or its obligation to make Eurodollar 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)); or (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 Eurodollar Rate hereunder; 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 Eurodollar Loan, Competitive U.S. Loan or Revolving Canadian Loan, issuing or participating in any U.S. Letter of Credit, of issuing or participating in any Canadian Letter of Credit or of accepting any Bankers' Acceptance or to reduce any amount receivable hereunder in respect thereof, then, in any such case, upon notice to the Credit Parties from such Lender, through an Agent, in accordance herewith, the Credit Parties 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, Airgas may elect to convert the Eurodollar Loans made by such U.S. Lender hereunder to U.S. Base Rate Loans by giving the U.S. Agent at least one Business Day's notice of such election, in which case Airgas shall promptly pay to such U.S. 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 Eurodollar Loan, Competitive U.S. Loan or Revolving Canadian Loan, of issuing or participating in any U.S. Letter of Credit, of issuing or participating in any Canadian Letter of Credit or of accepting any Bankers' Acceptance by a material amount, then such U.S. Lender will credit to Airgas 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 the Credit Parties, through the appropriate Agent, certifying (x) that one of the events described in this paragraph (a) 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 appropriate Agent, to the Credit Parties 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 Credit Parties, together with interest thereon at the Base Rate. This covenant shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder. EX-57 4.10 Taxes. (a) Except as provided below in this subsection, all payments made by the Credit Parties under this Credit Agreement and any Notes 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 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 or any Notes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts payable to an Agent or any Lender hereunder or under any Notes, (A) the amounts so payable to such Agent or such Lender shall be increased to the extent necessary to yield to such 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 and any Notes, provided, however, that the Credit Parties shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of paragraph (b) of this subsection whenever any Non-Excluded Taxes are payable by the Credit Parties, and (B) as promptly as possible thereafter the Credit Parties shall send to such 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 Credit Parties showing payment thereof. If the Credit Parties fail to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to such Agent the required receipts or other required documentary evidence, the Credit Parties shall indemnify such Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by such Agent or any Lender as a result of any such failure. 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 Credit Parties, together with interest thereon at the Base Rate. The agreements in this subsection shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder. (b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall: (X)(i)on or before the date of any payment by Airgas under this Credit Agreement or Notes to such Lender, deliver to Airgas and the U.S. Agent (A) two (2) duly completed copies of United States Internal Revenue Service Form 1001 or 4224, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Credit Agreement and any Notes without deduction or withholding of any United States federal income taxes and (B) an Internal Revenue Service Form W-8 or W-9, or successor EX-58 applicable form, as the case may be, certifying that it is entitled to an exemption from United States backup withholding tax; (ii) deliver to Airgas and the U.S. Agent two (2) further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to Airgas; and (iii) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by Airgas or the U.S. Agent; or (Y) in the case of any such Lender that is not a "bank" within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (i) represent to Airgas (for the benefit of Airgas and the U.S. Agent) that it is not a bank within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (ii) agree to furnish to Airgas on or before the date of any payment by Airgas, with a copy to the U.S. Agent two (2) accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender's legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Internal Revenue Code with respect to payments to be made under this Credit Agreement and any Notes (and to deliver to Airgas and the U.S. Agent two (2) further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by Airgas or the U.S. Agent for filing and completing such forms), and (iii) agree, to the extent legally entitled to do so, upon reasonable request by Airgas, to provide to Airgas (for the benefit of Airgas and the U.S. Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Credit Agreement and any Notes; unless in any such case any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises Airgas and the U.S. Agent. Each Person that shall become a Lender or a participant of a Lender pursuant to subsection 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection, provided that in the case of a participant of a Lender the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased. 4.11 Indemnity. Airgas promises to indemnify each U.S. Lender and to hold each U.S. Lender harmless from any loss or expense which such U.S. Lender may sustain or incur (other than through such U.S. Lender's breach of its obligations hereunder, gross negligence or willful misconduct) as a consequence of (a) default by Airgas in making a borrowing of, conversion into or continuation of Eurodollar Loans or Quoted Rate U.S. Swingline Loans after Airgas has given a notice requesting the same in accordance with the provisions of this Credit Agreement, (b) default by Airgas in making any prepayment of a Eurodollar Loan or a Quoted Rate U.S. Swingline Loan after Airgas has given a notice thereof in accordance with the provisions of this Credit Agreement or (c) the making of a prepayment of Eurodollar Loans or Quoted Rate U.S. Swingline Loans EX-59 on a day which is not the last day of an Interest Period with respect thereto. With respect to Eurodollar 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 Eurodollar Loans provided for herein (excluding, however, the Applicable Percentage included therein, if any) over (ii) the amount of interest (as reasonably determined by such U.S. Lender) which would have accrued to such U.S. Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurodollar 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 Pro Rata Treatment. Except to the extent otherwise provided herein: (a) Loans. (i) U.S. Dollar Loans. Each Revolving U.S. Loan or 364-Day Revolving Loan, each payment or prepayment of principal in respect of any Revolving U.S. Loan or 364-Day Revolving Loan or reimbursement obligations arising from drawings under U.S. Letters of Credit or from Participation Interests in U.S. Swingline Loans, each payment of interest on the Revolving U.S. Loans or 364-Day Revolving Loans or reimbursement obligations arising from drawings under U.S. Letters of Credit, each payment of the Unused Revolving U.S Commitment Fee or the Unused 364-Day Revolving Commitment Fees, each payment of the Standby U.S. Letter of Credit Fee, each payment of the Trade U.S. Letter of Credit Fee, each reduction of the Revolving U.S. Committed Amount or the 364-Day Revolving Committed Amount and each conversion or extension of any Revolving U.S. Loan or 364-Day Revolving Loan, shall be allocated pro rata among the U.S. Lenders in accordance with the respective principal amounts of their outstanding Revolving U.S. Loans and Participation Interests in Revolving U.S. Loans, U.S. Letters of Credit and U.S. Swingline Loans or their outstanding 364-Day Revolving Loans and Participation Interests in 364-Day Revolving Loans, as applicable. With respect to Competitive U.S. Loans, if Airgas fails to specify the particular Competitive U.S. Loan or Loans as to which any payment or other amount should be applied and it is not otherwise clear as to the particular Competitive U.S. Loan or Loans to which such payment or other amounts relate, or any such payment or other amount is to be applied to Competitive U.S. Loans without regard to any such direction by Airgas, then each payment or prepayment of principal on Competitive U.S. Loans and each payment of interest or other amount on or in respect of Competitive U.S. Loans, shall be allocated pro rata among the relevant U.S. Lenders in accordance with the then outstanding amounts of their respective Competitive U.S. Loans. (ii) Canadian Dollar Loans. Each Revolving Canadian Loan, each creation of a Bankers' Acceptance, each payment or prepayment of principal in respect of any Revolving Canadian Loan, BA Outstandings or reimbursement obligations arising from drawings under Canadian Letters of Credit, each payment of interest on the Revolving Canadian Loans or on reimbursement obligations arising from drawings under Canadian Letters of Credit, each payment of the Acceptance Fee on Bankers' Acceptances, each payment of the Unused Revolving Canadian Commitment Fee, each payment of the Standby Canadian Letter of Credit Fee, each payment of the Trade Canadian Letter of Credit Fee, each reduction of the Revolving Canadian Committed Amount and each conversion EX-60 or extension of any Revolving Canadian Loan, shall be allocated pro rata among the Canadian Lenders in accordance with the respective principal amounts of their outstanding Revolving Canadian Loans, BA Outstandings and Participation Interests in Revolving Canadian Loans, Canadian Letters of Credit and BA Outstandings. (b) Advances. Unless the U.S. Agent or the Canadian Agent, as appropriate, shall have been notified in writing by any Lender prior to any extension of credit that such Lender will not make the amount that would constitute its ratable share of such extension of credit available to such Agent, such Agent may assume that such Lender is making such amount available to such Agent, and such Agent may, in reliance upon such assumption, make available to the relevant Credit Party(ies) a corresponding amount. If such amount is not made available to the applicable Agent by such Lender within the time period specified therefor hereunder, such Lender shall pay to such Agent, on demand, such amount with interest thereon at a rate equal to, in the case of any extension of credit in U.S. Dollars, the Federal Funds Rate, or, in the case of any extension of credit in Canadian Dollars, the interbank rate (as defined in the Canadian Payment Association Rules), for the period until such Lender makes such amount immediately available to such Agent. A certificate of the U.S. Agent or the Canadian Agent, as applicable, submitted to any Lender with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. 4.13 Sharing of Payments. The Lenders agree among themselves that, in the event that any Lender shall obtain payment in respect of any Loan, LOC Obligations, BA Outstandings or any other obligation owing to such Lender under this Credit Agreement through the exercise of a right of setoff, banker's lien or counterclaim, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code (or similar provision of the Canadian bankruptcy laws) or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, in excess of its pro rata share of such payment as provided for in this Credit Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Loans, LOC Obligations, BA Outstandings and other obligations in such amounts, and make such other adjustments from time to time, as shall be equitable to the end that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Credit Agreement. The Lenders further agree among themselves that if payment to a Lender obtained by such Lender through the exercise of a right of setoff, banker's lien, counterclaim or other event as aforesaid shall be rescinded or must otherwise be restored, each Lender which shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit (together with its share of any accrued interest payable with respect thereto) to each Lender whose payment shall have been rescinded or otherwise restored. The Credit Parties agree that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including setoff, banker's lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Loan, LOC Obligations, BA Outstandings or other obligation in the amount of such participation. Except as otherwise expressly provided in this Credit Agreement, if any Lender or an Agent shall fail to remit to an Agent or any other Lender an amount payable by such Lender or such Agent to an Agent or such other Lender pursuant to this Credit Agreement on the date when such amount is due, such payments shall be made together with interest thereon for each date from the date such amount is due until the date such amount is paid to the Agent or such other Lender at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar EX-61 law, any Lender receives a secured claim in lieu of a setoff to which this Section 4.13 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 4.13 to share in the benefits of any recovery on such secured claim. 4.14 Payments, Computations, Etc. Except as otherwise specifically provided herein, (i) all payments in respect of Revolving Canadian Loans, Canadian Swingline Loans, Canadian Letters of Credit, Bankers' Acceptances, interest on Revolving Canadian Loans, the Acceptance Fee on Bankers' Acceptances or the Unused Revolving Canadian Commitment Fee shall be made to the Canadian Agent in Canadian Dollars in immediately available funds, without offset, deduction, counterclaim or withholding of any kind, at the Canadian Agent's office specified in Schedule 2.1(a) not later than 2:00 P.M. (Toronto, Ontario time) on the date when due and (ii) all other payments hereunder (other than payments in respect of Competitive U.S. Loans) shall be made to the U.S. Agent in dollars in immediately available funds, without offset, deduction, counterclaim or withholding of any kind, at the U.S. Agent's office specified in Schedule 2.1(a) not later than 2:00 P.M. (Charlotte, North Carolina time) on the date when due. Payments received after such times shall be deemed to have been received on the next succeeding Business Day. The relevant 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 Credit Parties maintained with such Agent (with notice to such Credit Parties). Each Credit Party shall, at the time it makes any payment under this Credit Agreement (other than payments in respect of Competitive U.S. Loans), specify to the relevant Agent the Loans, LOC Obligations, BA Outstandings, Fees, Acceptance Fees, interest or other amounts payable by the Credit Parties hereunder to which such payment is to be applied (and in the event that it fails so to specify, or if such application would be inconsistent with the terms hereof, such Agent shall distribute such payment to the Lenders in such manner as such Agent may determine to be appropriate in respect of obligations owing by the Credit Parties hereunder, subject to the terms of Section 4.12(a)). The U.S. Agent or the Canadian Agent, as applicable, will distribute such payments to such Lenders, if any such payment is received prior to 12:00 NOON (Charlotte, North Carolina time or Toronto, Ontario time, as applicable) on a Business Day in like funds as received prior to the end of such Business Day and otherwise such Agent will distribute such payment to such Lenders on the next succeeding Business Day. All payments of principal and interest in respect of Competitive U.S. Loans shall be in accordance with the terms of Section 2.2. Whenever any payment hereunder shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day (subject to accrual of interest and Fees for the period of such extension), except that in the case of Eurodollar Loans, if the extension would cause the payment to be made in the next following calendar month, then such payment shall instead be made on the next preceding Business Day. Except as expressly provided otherwise herein, all computations of interest and fees shall be made on the basis of actual number of days elapsed over a year of 360 days, except with respect to computation of interest on U.S. Base Rate Loans which (unless the U.S. Base Rate is determined by reference to the Federal Funds Rate) shall be calculated based on a year of 365 or 366 days, as appropriate. Interest shall accrue from and include the date of borrowing, but exclude the date of payment. EX-62 SECTION 5 CONDITIONS 5.1 Closing Conditions.

Each Credit Party has the corporate or other necessary power and authority, and the legal right, to make, deliver and perform the Credit Documents and to borrow hereunder, and has taken all necessary corporate action to authorize the borrowings on the terms and conditions of this Credit Agreement and to authorize the execution, delivery and performance of the Credit Documents to which it is a party. No consent or authorization of, filing with, notice to or other similar act by or in respect of, any Governmental Authority or any other Person is required to be obtained or made by or on behalf of any Credit Party in connection with the borrowings hereunder or with the execution, delivery, performance, validity or enforceability of the Credit Documents to which such Credit Party is a party. This Credit Agreement has been, and each other Credit Document to which any Credit Party is a party will be, duly executed and delivered on behalf of each such Credit Party. This Credit Agreement constitutes, and each other Credit Document when executed and delivered will constitute, a legal, valid and binding obligation of each Credit Party (with regard to each Credit Document to which it is a party) enforceable against such Credit Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 6.5 No Legal Bar. The execution, delivery and performance of the Credit Documents by any Credit Party, the borrowings hereunder and the use of the proceeds thereof (a) will not violate any Requirement of Law or contractual obligation of such Credit Party or any of its Subsidiaries in any respect that would reasonably be expected to have a Material Adverse Effect, (b) will not result in, or require, the creation or imposition of any Lien on any of the properties or revenues of such Credit Party or any of its Subsidiaries pursuant to any such Requirement of Law or contractual obligation, and (c) will not violate or conflict with any provision of such Credit Party's articles of incorporation or by-laws. 6.6 No Material Litigation.

No Consolidated Party or any ERISA Affiliate has received any notification that any Multiemployer Plan is in reorganization (within the meaning of Section 4241 of ERISA), is insolvent (within the meaning of Section 4245 of ERISA), or has been terminated (within the meaning of Title IV of ERISA), and no Multiemployer Plan is, to the best knowledge of Airgas, reasonably expected to be in reorganization, insolvent, or terminated. (d) No prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) or breach of fiduciary responsibility has occurred with respect to a Plan which has subjected or may subject any Consolidated Party or any ERISA Affiliate to any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code, or under any agreement or other instrument pursuant to which any Consolidated Party or any ERISA Affiliate has agreed or is required to indemnify any person against any such liability. 6.13 Governmental Regulations, Etc. (a) No part of the proceeds of the Loans will be used, directly or indirectly, for the purpose of purchasing or carrying any "margin stock" within the meaning of Regulation G or Regulation U, or for the purpose of purchasing or carrying or trading in any securities other than securities issued by Airgas. If requested by any Lender or the U.S. Agent, the Credit Parties will furnish to the U.S. Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form U-1 referred to in said Regulation U. No indebtedness being reduced or retired out of the proceeds of the Loans was or will be incurred for the purpose of purchasing or carrying any margin stock within the meaning of Regulation U or any "margin security" within the meaning of Regulation T other than securities issued by Airgas. "Margin stock" within the meanings of Regulation U does not constitute more than 25% of the value of the consolidated assets of the Consolidated Parties. None of the transactions contemplated by this Credit Agreement (including, without limitation, the direct or indirect use of the proceeds of the Loans) will violate or result in a violation of the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, or regulations issued pursuant thereto, or Regulation G, T, U or X. (b) No Consolidated Party is subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act or the Investment Company Act of 1940, each as amended.

The provisions of this Section are solely for the benefit of the Agents and the Lenders, and the Credit Parties shall have no rights as a third party beneficiary of the provisions hereof. In performing its functions and duties under this Credit Agreement and the other Credit Documents, the U.S. Agent shall act solely as agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation or relationship of agency or trust with or for the Credit Parties or any of their respective Affiliates. In performing its functions and duties under this Credit Agreement and the other Credit Documents, the Canadian Agent shall act solely as agent of the Canadian Lenders and does not assume and shall not be deemed to have assumed any obligation or relationship of agency or trust with or for the Credit Parties or any of their respective Affiliates. 10.2 Delegation of Duties. Each of the Agents may execute any of its duties hereunder or under the other Credit Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties.

Each of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall not be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection herewith or in connection with any of the other Credit Documents (except for its or such Person's own gross negligence or willful misconduct), or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Credit Party contained herein or in any of the other Credit Documents or in any certificate, report, document, financial statement or other written or oral statement referred to or provided for in, or received by an Agent under or in connection herewith or EX-80 in connection with the other Credit Documents, or enforceability or sufficiency therefor of any of the other Credit Documents, or for any failure of any Credit Party to perform its obligations hereunder or thereunder. Neither of the Agents shall be responsible to any Lender for the effectiveness, genuineness, validity, enforceability, collectability or sufficiency of this Credit Agreement, or any of the other Credit Documents or for any representations, warranties, recitals or statements made herein or therein or made by any Credit Party in any written or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by such Agent to the Lenders or by or on behalf of the Credit Parties to such Agent or any Lender or be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or as to the use of the proceeds of the Loans or the use of the Letters of Credit or of the existence or possible existence of any Default or Event of Default or to inspect the properties, books or records of any Credit Party or any of its respective Affiliates. Neither of the Agents is a trustee for any Lenders or owes any fiduciary duty to any Lenders. 10.4 Reliance on Communications. Each of the Agents shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Credit Parties, independent accountants and other experts selected by the U.S. Agent with reasonable care). Each of the Agents may deem and treat each Lender as the owner of its interests hereunder for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with such Agent in accordance with Section 11.3(b) hereof. Each of the Agents shall be fully justified in failing or refusing to take any action under this Credit Agreement or under any of the other Credit Documents unless it shall first receive such advice or concurrence as it deems appropriate from, in the case of the U.S. Agent, the Required Lenders, or, in the case of the Canadian Agent, the Required Canadian Lenders, or it shall first be indemnified to its satisfaction by, in the case of the U.S. Agent, the Lenders, or, in the case of the Canadian Agent, the Canadian Lenders, against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any of the other Credit Documents in accordance with a request of, in the case of the U.S. Agent, the Required Lenders, or, in the case of the Canadian Agent, the Required Canadian Lenders (or, in the case of the U.S. Agent or the Canadian Agent, all the Lenders to the extent specifically provided in Section 10.6) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders (including their successors and assigns). 10.5 Notice of Default. Neither of the Agents shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless such Agent has received notice from a Lender or a Credit Party referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a "notice of default." In the event that either Agent receives such a notice, such Agent shall give prompt notice thereof to, in the case of the U.S. Agent, all of the Lenders, or, in the case of the Canadian Agent, the EX-81 Canadian Lenders. The U.S. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders. 10.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly acknowledges that neither of the Agents nor any of their officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by an Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Credit Parties or any of their respective Affiliates, shall be deemed to constitute any representation or warranty by such Agent to any Lender. Each Lender represents to each of the Agents that it has, independently and without reliance upon the Agents or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Credit Parties or their respective Affiliates and made its own decision to make its Loans hereunder and enter into this Credit Agreement. Each Lender also represents that it will, independently and without reliance upon the Agents or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Credit Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Credit Parties and their respective Affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders (or any of them) by such Agent hereunder, neither of the Agents shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, assets, property, financial or other conditions, prospects or creditworthiness of the Credit Parties or any of their respective Affiliates which may come into the possession of such Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 10.7 Indemnification. The Lenders agree to indemnify the U.S. Agent in its capacity as such (to the extent not reimbursed by the Credit Parties and without limiting the obligation of the Credit Parties to do so), ratably (according to (i) the sum of the Dollar Amount of (A) the Revolving U.S. Commitments, (B) the 364-Day Revolving Commitments, (C) the Revolving Canadian Commitments, and (D) the outstanding principal amount of any 364-Day Revolving Loans which have been converted to term loans pursuant to Section 2.5(f) (and Participation Interests therein) or (ii) if the Commitments have been terminated, the sum of the Dollar Amount of (A) the outstanding Loans, (B) the outstanding Participation Interests (including the Participation Interests of the U.S. Issuing Lender in any U.S. Letters of Credit, the Participation Interests of the U.S. Swingline Lender in any U.S. Swingline Loans and the Participation Interests of the Canadian Issuing Lender in any Canadian Letters of Credit), (C) the Canadian LOC Obligations and (D) the BA Outstandings), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including without limitation at any time following the final payment of all of the obligations of the Credit Parties hereunder and under the other Credit Documents) be imposed on, incurred by or asserted against the U.S. Agent in its capacity as such in any way relating to or arising out of this Credit Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the U.S. EX-82 Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the U.S. Agent. If any indemnity furnished to the U.S. Agent for any purpose shall, in the opinion of the U.S. Agent, be insufficient or become impaired, the U.S. Agent may call for additional indemnity from the Lenders and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The Canadian Lenders agree to indemnify the Canadian Agent in its capacity as such (to the extent not reimbursed by the Credit Parties and without limiting the obligation of the Credit Parties to do so), ratably according to their respective Commitments (or if the Commitments have expired or been terminated, in accordance with the respective principal amounts of outstanding Loans and Participation Interests of the Lenders), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including without limitation at any time following the final payment of all of the obligations of the Credit Parties hereunder and under the other Credit Documents) be imposed on, incurred by or asserted against the Canadian Agent in its capacity as such in any way relating to or arising out of this Credit Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Canadian Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Canadian Agent. If any indemnity furnished to the Canadian Agent for any purpose shall, in the opinion of the Canadian Agent, be insufficient or become impaired, the Canadian Agent may call for additional indemnity from the Canadian Lenders and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section shall survive the repayment of the Loans, LOC Obligations, BA outstandings and other obligations under the Credit Documents and the termination of the Commitments hereunder. Nothing set forth in this Section 10.7 shall effect any obligation arising under the Credit Documents of either of the Agents to any of the Credit Parties. 10.8 Agents in their Individual Capacity. Each of the Agents and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Consolidated Parties or their respective Affiliates as though such Agent were not an Agent hereunder. With respect to the Loans made by and all obligations of the Credit Parties hereunder and under the other Credit Documents, each Agent shall have the same rights and powers under this Credit Agreement as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include the U.S. Agent and the Canadian Agent in their individual capacities. 10.9 Successor Agents. Either of the Agents may, at any time, resign upon 45 days' written notice to the Lenders and Airgas, and be removed with or without cause by the Required Lenders upon 30 days' written notice to the Agents and Airgas. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor U.S. Agent or successor Canadian Agent, as applicable, acceptable to Airgas. If no successor U.S. Agent or successor Canadian Agent, as applicable, shall have been so appointed (and accepted such appointment) within 30 days after the notice of resignation or notice of removal, as EX-83 appropriate, then the retiring U.S. Agent or Canadian Agent, as applicable, shall select a successor U.S. Agent or successor Canadian Agent, as applicable, acceptable to Airgas, provided such successor is a Lender hereunder or, in the case of a successor U.S. Agent, a commercial bank organized under the laws of the United States of America or of any State thereof and has a combined capital and surplus of at least U.S.$1,000,000,000, or, in the case of a successor Canadian Agent, a commercial bank organized under the laws of Canada or of any Province thereof and has a combined capital and surplus of at least C$1,000,000,000. Upon the acceptance of any appointment as U.S. Agent or Canadian Agent, as applicable, hereunder by a successor, such successor U.S. Agent or successor Canadian Agent, as applicable, shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring U.S. Agent or Canadian Agent, as applicable, and the retiring U.S. Agent or Canadian Agent, as applicable, shall be discharged from its duties and obligations as U.S. Agent or Canadian Agent, as applicable, under this Credit Agreement and the other Credit Documents and the provisions of this Section 10.9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was an Agent under this Credit Agreement.

In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence of an Event of Default, each Lender is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind (all of which rights being hereby expressly waived), to set-off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Lender (including, without limitation branches, agencies or Affiliates of such Lender wherever located) to or for the credit or the account of a Credit Party against obligations and liabilities of such Person to such Lender hereunder, under the Notes, the other Credit Documents or otherwise, irrespective of whether such Lender shall have made any demand hereunder and although such obligations, liabilities or claims, or any of them, may be contingent or unmatured, and any such set-off shall be deemed to have been made immediately upon the occurrence of an Event of Default even though such charge is made or entered on the books of such Lender subsequent thereto. Any Person purchasing EX-85 a participation in the Loans and Commitments hereunder pursuant to Section 4.13 or Section 11.3(c) may exercise all rights of set-off with respect to its participation interest as fully as if such Person were a Lender hereunder. 11.3 Benefit of Agreement. (a) Generally. This Credit Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided that a Credit Party may not assign or transfer any of its interests without prior written consent of all the Lenders; provided further that the rights of each Lender to transfer, assign or grant participations in its rights and/or obligations hereunder shall be limited as set forth in this Section 11.3, provided however that nothing herein shall prevent or prohibit any Lender from (i) pledging its Loans hereunder to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank, or (ii) granting assignments or selling participations in such Lender's Loans and/or Commitments hereunder to its parent company and/or to any Affiliate or Subsidiary of such Lender. (b) Assignments. Each Lender may assign all or a portion of its rights and obligations hereunder, pursuant to an assignment agreement substantially in the form of Schedule 11.3(b), to (i) any Lender, any Subsidiary of a Lender or any Affiliate of a Lender under direct or indirect common control with such Lender, or (ii) any other commercial bank, financial institution or "accredited investor" (as defined in Regulation D of the Securities and Exchange Commission) reasonably acceptable to the U.S. Agent, Airgas and, in the case of any assignment by a Canadian Lender, the Canadian Agent (provided that it shall not be unreasonable for Airgas to withhold its approval for any assignment to any competitor of Airgas (which term "competitor" shall not include a Person solely by reason of the fact that such Person is making loans to, accepting deposits from or otherwise generally engaging in banking business with any competitor of Airgas); provided that (i)(A) in the case of any assignment by a U.S. Lender of all or any portion of such U.S. Lender's Revolving U.S. Commitment or 364-Day Revolving Commitment, (other than any assignment to an existing Lender), such assignment shall be in a minimum aggregate amount of U.S.$5,000,000 of such Commitments and in integral multiples of U.S.$1,000,000 above such amount (or, if less, the remaining amount of the Commitment being assigned by such U.S. Lender) or (B) in the case of any assignment by a Canadian Lender of all or any portion of such Canadian Lender's Revolving Canadian Commitment (other than any assignment to an existing Lender), such assignment shall be in a minimum aggregate amount of C$1,500,000 of such Commitment and in integral multiples of C$100,000 above such amount (or, if less, the remaining amount of the Commitment being assigned by such Canadian Lender) and (ii) each such assignment shall be of a constant, not varying, percentage of all such Lender's rights and obligations under this Credit Agreement. Any assignment of all or any portion of a U.S. Lender's Revolving U.S. Commitment or 364-Day Revolving Commitment hereunder shall be effective upon delivery to the U.S. Agent of written notice of the assignment together with a transfer fee of U.S.$3,500 payable to the U.S. Agent for its own account from and after the effective date specified in the applicable assignment agreement. Any assignment of all or any portion of a Canadian Lender's Revolving Canadian Commitment hereunder shall be effective upon (i) delivery to the U.S. Agent and Canadian Agent of written notice of the assignment and (ii) payment of a transfer fee of C$3,500 payable to the Canadian Agent for its own account from and after the effective date specified in the applicable assignment agreement. In addition, the assigning Lender will give prompt notice to Airgas of any such assignment. Upon the effectiveness of any such assignment (and after notice to, and (to the extent required pursuant to the terms hereof), with the consent of, Airgas as provided herein), the assignee shall become a "Lender" for all purposes of EX-86 this Credit Agreement and the other Credit Documents and, to the extent of such assignment, the assigning Lender shall be relieved of its obligations hereunder to the extent of the Loans and Commitment components being assigned. Along such lines each Credit Party agrees that upon notice of any such assignment and surrender of the appropriate Note or Notes, it will promptly provide to the assigning Lender and to the assignee separate promissory notes in the amount of their respective interests substantially in the form of the original Note (but with notation thereon that it is given in substitution for and replacement of the original Note or any replacement notes thereof). By executing and delivering an assignment agreement in accordance with this Section 11.3(b), the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim; (ii) except as set forth in clause (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto or the financial condition of any Credit Party or any of its respective Affiliates or the performance or observance by any Credit Party of any of its obligations under this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (iii) such assignee represents and warrants that it is legally authorized to enter into such assignment agreement; (iv) such assignee confirms that it has received a copy of this Credit Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such assignment agreement; (v) such assignee will independently and without reliance upon the Agents, such assigning Lender or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Credit Agreement and the other Credit Documents; (vi) such assignee appoints and authorizes the Agents to take such action on its behalf and to exercise such powers under this Credit Agreement or any other Credit Document as are delegated to the Agents by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Credit Agreement and the other Credit Documents are required to be performed by it as a Lender. (c) Participations. Each Lender may sell, transfer, grant or assign participations in all or any part of such Lender's interests and obligations hereunder; provided that (i) such selling Lender shall remain a "Lender" for all purposes under this Credit Agreement (such selling Lender's obligations under the Credit Documents remaining unchanged) and the participant shall not constitute a Lender hereunder, (ii) no such participant shall have, or be granted, rights to approve any amendment or waiver relating to this Credit Agreement or the other Credit Documents except to the extent any such amendment or waiver would (A) reduce the principal of or rate of interest on or Fees in respect of any Loans in which the participant is participating, (B) postpone the date fixed for any payment of principal (including extension of the Termination Date or the date of any mandatory prepayment), interest or Fees in which the participant is participating or (C) alter the obligations of the Guarantor, and (iii) sub-participations by the participant (except to an affiliate, parent company or affiliate of a parent company of the participant) shall be prohibited. In the case of any such participation, the participant shall not have any rights under this Credit Agreement or the other Credit EX-87 Documents (the participant's rights against the selling Lender in respect of such participation to be those set forth in the participation agreement with such Lender creating such participation) and all amounts payable by the Credit Parties hereunder shall be determined as if such Lender had not sold such participation, provided, however, that such participant shall be entitled to receive additional amounts under Sections 4.6, 4.9, 4.10 and 4.11 to the same extent as if it were a Lender provided that it shall not be entitled to receive any more than the selling Lender would have received had it not sold the participation. 11.4 No Waiver; Remedies Cumulative. No failure or delay on the part of an Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between an Agent or any Lender and the Credit Parties 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 Agents or any Lender would otherwise have. No notice to or demand on the Credit Parties in any case shall entitle the Credit Parties to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the U.S. Agent or the Lenders to any other or further action in any circumstances without notice or demand. 11.5 Payment of Expenses, Etc. The Credit Parties agree to: (i) pay all reasonable out-of-pocket costs and expenses (A) of the U.S. 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 Moore & Van Allen, PLLC, special counsel to the Agents as well as Canadian counsel to the Agents) 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 Credit Parties under this Credit Agreement and (B) of the U.S. 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 U.S. Agent and each of the Lenders); (ii) pay and hold 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 each 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 any Agent or 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 EX-88 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). 11.6 Amendments, Waivers and Consents. Neither this Credit Agreement nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing entered into by, or approved in writing by, the Required Lenders and the Credit Parties, provided that no such amendment, change, waiver, discharge or termination shall, without the consent of each Lender: (i) extend the final maturity of any Loan or of any reimbursement obligations arising from drawings under Letters of Credit, or any portion thereof; (ii) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) on any Loan or of any reimbursement obligations arising from drawings under Letters of Credit or fees hereunder; (iii) reduce the principal amount on any Loan or of any reimbursement obligations arising from drawings under Letters of Credit or the amount of any accrued interest or Fees, or increase the Commitments of the Lenders over the amount thereof in effect (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); (iv) amend, modify or waive any provision of this Section 11.6 or Section 4.6, 4.10, 4.11, 4.12, 4.13, 9.1(a), 11.2, 11.3, 11.5 or 11.9; (v) reduce any percentage specified in, or otherwise modify, the definition of "Required Lenders"; (vi) consent to the assignment or transfer by any Credit Party of any of its rights and obligations under (or in respect of) the Credit Documents to which it is a party or (vi) alter the obligations of the Guarantor.

(c) With respect to the guaranty obligations of Airgas arising under Section 3.5: (i) (A) Without limiting the generality of subsections (a) and (b) of this Section 11.10, Airgas 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 Canadian Agent and the Canadian EX-90 Lenders, be settled immediately by submitting the same to binding arbitration in the City of Charlotte, North Carolina (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 Canadian Agent shall give Airgas 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. Airgas 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 (ii) below, including without limitation any court of the State of North Carolina or any Federal court sitting in the State of North Carolina.

(ii) The guarantee of Airgas under Section 3.5 is an international transaction in which payment of Canadian Dollars in Toronto, Ontario, Canada, is of the essence, and Canadian Dollars shall be the currency of account in all events in respect of the guaranty obligations of Airgas under Section 3.5. The payment obligation of Airgas shall not be discharged by an amount paid in another currency or in another place, whether pursuant to a judgment or otherwise, to the extent that the amount so paid on prompt conversion to dollars and transfer to Toronto, Ontario, Canada, under normal banking procedures does not yield the amount of dollars in Toronto, Ontario, Canada due hereunder. In the event that any payment by Airgas, whether pursuant to a judgment or otherwise, upon conversion and transfer does not result in payment of such amount of dollars in Toronto, Ontario, Canada, the Canadian Agent and the Canadian Lenders shall have a separate cause of action against Airgas for the additional amount necessary to yield the amount due and owing to the Canadian Agent and the Canadian Lenders.
