(b) Notice and Reports. The request for the issuance of a U.S. Letter of

Credit shall be submitted by Airgas (by its duly authorized officers or

representatives) to the U.S. Issuing Lender with a copy to the U.S. Agent at

least three (3) Business Days prior to the requested date of issuance. The U.S.

Issuing Lender will, at least quarterly and more frequently upon request,

disseminate to each of the U.S. Revolving Lenders a detailed report specifying

the U.S. Letters of Credit which are then issued and outstanding and any

activity with respect thereto which may have occurred since the date of the

prior report, and including therein, among other things, the beneficiary, the

face amount, expiry date as well as any payment or expirations which may have

occurred.

(c) Participation. Each U.S. Revolving Lender, upon issuance of a U.S.

Letter of Credit (or, in the case of each Existing U.S. Letter of Credit, on the

Closing Date), shall be deemed to have purchased without recourse a risk

participation from the U.S. Issuing Lender in such U.S. Letter of Credit and the

obligations arising thereunder, in each case in an amount equal to its pro rata

share of the obligations under such U.S. Letter of Credit (based on the

respective U.S. Revolving Commitment Percentages of the U.S. Revolving Lenders)

and shall absolutely, unconditionally and irrevocably assume, as primary obligor

and not as surety, and be obligated to pay to the U.S. Issuing Lender therefor

and discharge when due, its pro rata share of the obligations arising under such

U.S. Letter of Credit. Without limiting the scope and nature of each U.S.

Revolving Lender's participation in any U.S. Letter of Credit, to the extent

that the U.S. Issuing Lender has not been reimbursed as required hereunder or

under any such U.S. Letter of Credit, each such U.S. Revolving Lender shall pay

to the U.S. Issuing Lender its pro rata share of such unreimbursed drawing in

same day funds on the day of notification by the U.S. Issuing Lender of an

unreimbursed drawing pursuant to the provisions of subsection (d) hereof. The

obligation of each U.S. Revolving Lender to so reimburse the U.S. Issuing Lender

shall be absolute and unconditional and shall not be affected by the occurrence

of a Default, an Event of Default or any other occurrence or event. Any such

reimbursement shall not relieve or otherwise impair the obligation of Airgas to

reimburse the U.S. Issuing Lender under any U.S. Letter of Credit, together with

interest as hereinafter provided.

(d) Reimbursement. In the event of any drawing under any U.S. Letter of

Credit, the U.S. Issuing Lender will promptly notify Airgas and the U.S. Agent.

Unless Airgas shall immediately notify the U.S. Issuing Lender that Airgas

intends to otherwise reimburse the U.S. Issuing Lender for such drawing, Airgas

shall be deemed to have requested that the U.S. Revolving Lenders make a U.S.

Revolving Loan in the 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 U.S. Revolving 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. Revolving 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. Agent will

promptly notify the other U.S. Revolving Lenders of the amount of any

unreimbursed drawing under any U.S. Letter of Credit and each U.S. Revolving

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. Revolving 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. Revolving

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. Revolving Lender does

not pay such amount to the U.S. Issuing Lender in full upon such request, such

U.S. Revolving Lender shall, on demand, pay to the 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. Revolving Lender pays such amount to the

U.S. Issuing Lender in full at a rate per annum equal to, if paid within two (2)

Business Days of the date that such U.S. Revolving Lender is required to make

payments of such amount pursuant to the preceding sentence, the Federal Funds

Rate and thereafter at a rate equal to the U.S. Base Rate. Each U.S. Revolving

Lender's obligation to make such payment to the U.S. Issuing Lender, and the

right of the U.S. Issuing Lender to receive the same, shall be absolute and

unconditional, shall not be affected by any circumstance whatsoever and without

regard to the termination of this Credit Agreement or the Commitments hereunder,

the existence of a Default or Event of Default or the acceleration of the

32

<PAGE>

obligations of Airgas hereunder and shall be made without any offset, abatement,

withholding or reduction whatsoever. Simultaneously with the making of each such

payment by a U.S. Revolving Lender to the U.S. Issuing Lender, such U.S.

Revolving Lender shall, automatically and without any further action on the part

of the U.S. Issuing Lender or such U.S. Revolving Lender, acquire a

participation in an amount equal to such payment (excluding the portion of such

payment constituting interest owing to the U.S. Issuing Lender) in the related

unreimbursed drawing portion of the U.S. LOC Obligation and in the interest

thereon and in the related U.S. LOC Documents, and shall have a claim against

Airgas with respect thereto.

(e) Repayment with U.S. Revolving Loans. On any day on which Airgas shall

have requested, or shall be deemed to have requested, a U.S. Revolving Loan

advance to reimburse a drawing under a U.S. Letter of Credit, the U.S. Agent

shall give notice to the U.S. Revolving Lenders that a U.S. Revolving Loan has

been requested or deemed requested by Airgas to be made in connection with a

drawing under a U.S. Letter of Credit, in which case a U.S. Revolving Loan

advance comprised of U.S. Base Rate Loans (or 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. Revolving Lenders

(notwithstanding any termination of the Commitments pursuant to Section 9.2) pro

rata based on the respective U.S. Revolving Commitment Percentages of the U.S.

Revolving 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 U.S. Revolving Lender hereby irrevocably agrees to make its

pro rata share of each such U.S. Revolving Loan immediately upon any such

request or deemed request in the amount, in the manner and on the date specified

in the preceding sentence notwithstanding (i) the amount of such borrowing may

not comply with the minimum amount for advances of U.S. Revolving Loans

otherwise required hereunder, (ii) whether any conditions specified in Section

5.2 are then satisfied, (iii) whether a Default or an Event of Default then

exists, (iv) failure for any such request or deemed request for U.S. Revolving

Loan to be made by the time otherwise required hereunder, (v) whether the date

of such borrowing is a date on which U.S. Revolving Loans are otherwise

permitted to be made hereunder or (vi) any termination of the Commitments

relating thereto immediately prior to or contemporaneously with such borrowing.

In the event that any U.S. Revolving Loan cannot for any reason be made on the

date otherwise required above (including, without limitation, as a result of the

commencement of a proceeding under the Bankruptcy Code with respect to Airgas),

then each U.S. Revolving Lender hereby agrees that it shall forthwith purchase

(as of the date such borrowing would otherwise have occurred, but adjusted for

any payments received from Airgas on or after such date and prior to such

purchase) from the U.S. Issuing Lender such participation in the outstanding

U.S. LOC Obligations as shall be necessary to cause each U.S. Revolving Lender

to share in such U.S. LOC Obligations ratably (based upon the respective U.S.

Revolving Commitment Percentages of the U.S. Revolving 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. Revolving 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 U.S. Revolving Loan advance, the Federal

Funds Rate, and thereafter at a rate equal to the U.S. Base Rate.

(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.

33

<PAGE>

(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) Applicability of ISP and UCP. Unless otherwise expressly agreed by the

U.S. Issuing Lender and Airgas when a U.S. Letter of Credit is issued (including

any such agreement applicable to an Existing U.S. Letter of Credit), (i) the

rules of the ISP shall apply to each standby U.S. Letter of Credit, and (ii) the

rules of the Uniform Customs and Practice for Documentary Credits, as most

recently published by the International Chamber of Commerce at the time of

issuance shall apply to each trade U.S. Letter of Credit.

(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. Revolving 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 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.

34

<PAGE>

(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.

Revolving Lenders are only those expressly set forth in this Credit Agreement

and that the U.S. Issuing Lender shall be entitled to assume that the conditions

precedent set forth in Section 5.2 have been satisfied unless it shall have

acquired actual knowledge that any such condition precedent has not been

satisfied; provided, however, that nothing set forth in this Section 2.3 shall

be deemed to prejudice the right of any U.S. Revolving Lender to recover from

the U.S. Issuing Lender any amounts made available by such U.S. Revolving Lender

to the U.S. Issuing Lender pursuant to this Section 2.3 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.

(l) Role of U.S. Agent. Airgas and each U.S. Issuing Lender agree to

provide the U.S. Agent with a copy of any notice or report otherwise required to

be furnished by such Person to any other Person pursuant to Sections 2.3(a),

2.3(b) or 2.3(d). Furthermore, all payments required to be made by any U.S.

Revolving Lender to a U.S. Issuing Lender pursuant to Section 2.3 shall be made

to the U.S. Agent, for the account of such U.S. Issuing Lender, and the U.S.

Agent shall distribute such payments to such U.S. Issuing Lender.

2.4 U.S. SWINGLINE LOAN SUBFACILITY.

(a) U.S. Swingline Commitment. Subject to the terms and conditions set

forth herein, the U.S. Swingline Lender agrees, in reliance upon the agreements

of the other U.S. Revolving Lenders set forth in this Section 2.4, the U.S.

Swingline Lender, in its individual capacity, agrees to make certain revolving

credit loans requested by Airgas in U.S. Dollars to Airgas (each a "U.S.

Swingline Loan" and, collectively, the "U.S. Swingline Loans") from time to time

from the Closing Date until the Termination Date for the purposes hereinafter

set forth; provided, however, (i) the aggregate principal amount of U.S.

Swingline Loans outstanding at any time shall not exceed THIRTY MILLION U.S.

DOLLARS ($30,000,000) (the "U.S. Swingline Committed Amount"), and (ii) the

aggregate principal amount of outstanding U.S. Revolving Loans plus the

aggregate principal amount of outstanding Competitive U.S. Loans plus the

aggregate principal amount of outstanding U.S. Swingline Loans plus U.S. LOC

Obligations outstanding shall not exceed the U.S. Revolving Committed Amount.

U.S. Swingline Loans hereunder shall be made as U.S. Base Rate Loans or Quoted

Rate U.S. Swingline Loans as Airgas may request in accordance with the

provisions of this Section 2.4, and may be repaid and reborrowed in accordance

with the provisions hereof.

(b) U.S. Swingline Loan Advances.

(i) Notices; Disbursement. Whenever Airgas desires a U.S. Swingline

Loan advance hereunder its duly authorized officer or representative shall

give written notice (or telephone notice promptly confirmed in writing) to

the U.S. Swingline Lender not later than 2:00 P.M. (Charlotte, North

Carolina time) on the Business Day of the requested U.S. Swingline Loan

advance. Each such notice shall be irrevocable and shall specify (A) that

a U.S. Swingline Loan advance is requested, (B) the date of the requested

U.S. Swingline Loan advance (which shall be a Business Day) and (C) the

principal amount of the U.S. Swingline Loan advance requested. Each U.S.

Swingline Loan shall be made as a U.S. Base Rate Loan or a Quoted Rate

U.S. Swingline Loan and shall have such maturity date as the U.S.

Swingline Lender and Airgas shall agree upon receipt by the U.S. Swingline

Lender of any such notice from Airgas. The U.S. Swingline Lender shall

credit

35

<PAGE>

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.

(ii) Minimum Amounts. Each U.S. Swingline Loan advance shall be in a

minimum principal amount of $100,000 and in integral multiples thereof (or

the remaining amount of the U.S. Swingline Committed Amount, if less).

(iii) Repayment of U.S. Swingline Loans. Airgas promises to pay the

principal amount of all U.S. Swingline Loans on the earlier of (A) the

maturity date agreed to by the U.S. Swingline Lender and Airgas with

respect to such U.S. Swingline Loan (which maturity date shall not be a

date more than thirty (30) days from the date of advance thereof) or (B)

the Termination Date. The U.S. Swingline Lender may, at any time, in its

sole discretion, by written notice to Airgas and the U.S. Revolving

Lenders, demand repayment of its U.S. Swingline Loans by way of a U.S.

Revolving Loan advance, in which case Airgas shall be deemed to have

requested a U.S. Revolving Loan advance comprised solely of U.S. Base Rate

Loans in the amount of such U.S. Swingline Loans; provided, however, that

any such demand 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. Revolving Lender hereby irrevocably

agrees to make its pro rata share of each such U.S. Revolving Loan in the

amount, in the manner and on the date specified in the preceding sentence

notwithstanding (I) the amount of such borrowing may not comply with the

minimum amount for advances of U.S. Revolving Loans otherwise required

hereunder, (II) whether any conditions specified in Section 5.2 are then

satisfied, (III) whether a Default or an Event of Default then exists,

(IV) failure of any such request or deemed request for U.S. Revolving Loan

to be made by the time otherwise required hereunder, (V) whether the date

of such borrowing is a date on which U.S. Revolving Loans are otherwise

permitted to be made hereunder or (VI) any termination of the Commitments

relating thereto immediately prior to or contemporaneously with such

borrowing. In the event that any U.S. Revolving Loan cannot for any reason

be made on the date otherwise required above (including, without

limitation, as a result of the commencement of a proceeding under the

Bankruptcy Code with respect to Airgas), then each U.S. Revolving Lender

hereby agrees that it shall forthwith purchase (as of the date such

borrowing would otherwise have occurred, but adjusted for any payments

received from Airgas on or after such date and prior to such purchase)

from the U.S. Swingline Lender such participations in the outstanding U.S.

Swingline Loans as shall be necessary to cause each U.S. Revolving Lender

to share in such U.S. Swingline Loans ratably based upon its U.S.

Revolving Commitment Percentage of the U.S. Revolving Committed Amount

(determined before giving effect to any termination of the Commitments

pursuant to Section 9.2), provided that (A) all interest payable on the

U.S. Swingline Loans shall be for the account of the U.S. Swingline Lender

until the date as of which the respective participation is purchased and

(B) at the time any purchase of participations pursuant to this sentence

is actually made, the purchasing U.S. Revolving Lender shall be required

to pay to the U.S. Swingline Lender, to the extent not paid to the U.S.

Swingline Lender by Airgas in accordance with the terms of 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:

36

<PAGE>

(A) U.S. Base Rate Loans. If such U.S. Swingline Loan is a U.S. Base

Rate Loan, at a per annum rate (computed on the basis of the actual number

of days elapsed over a year of 365 days) equal to the U.S. Base Rate plus

the Applicable Percentage; and

(B) Quoted Rate U.S. Swingline Loans. If such U.S. Swingline Loan is

a Quoted Rate U.S. Swingline Loan, at a per annum rate (computed on the

basis of the actual number of days elapsed over a year of 360 days) equal

to the Quoted Rate applicable thereto.

Notwithstanding any other provision to the contrary set forth in this

Credit Agreement, in the event that the principal amount of any Quoted

Rate U.S. Swingline Loan is not repaid on the last day of the Interest

Period for such Loan, then such Loan shall be automatically converted into

a U.S. Base Rate Loan at the end of such Interest Period.

(C) Payment of Interest. Airgas promises to pay interest on U.S.

Swingline Loans in arrears on each applicable Interest Payment Date (or at

such other times as may be specified herein).

2.5 U.S. TERM LOAN.

(a) U.S. Term Commitment. Subject to the terms and conditions hereof

and in reliance upon the representations and warranties set forth herein

each U.S. Term Lender severally agrees to make available to Airgas on the

Closing Date (or on the effective date of any increase in the U.S. Term

Loan Committed Amount pursuant to Section 4.4(b), as applicable) such U.S.

Term Lender's U.S. Term Loan Percentage of a term loan in U.S. Dollars

(the "U.S. Term Loan") in the aggregate principal amount equal to ONE

HUNDRED MILLION U.S. DOLLARS ($100,000,000) (as such aggregate maximum

amount may be increased from time to time as provided in Section 4.4, the

"U.S. Term Loan Committed Amount"). The U.S. Term Loan may consist of U.S.

Base Rate Loans or Eurodollar Loans, or a combination thereof, as Airgas

may request; provided, however, that no more than five (5) Eurodollar

Loans which are U.S. Term 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). Amounts repaid on the U.S.

Term Loan may not be reborrowed.

(b) Borrowing Procedures. Airgas shall submit an appropriate Notice

of Borrowing to the U.S. Agent not later than 11:00 A.M. (Charlotte, North

Carolina time) on the Closing Date (or on the effective date of any

increase in the U.S. Term Loan Committed Amount pursuant to Section

4.4(b), as applicable), with respect to the portion of the U.S. Term Loan

initially consisting of a U.S. Base Rate Loan, or on the third Business

Day prior to the Closing Date (or on the effective date of any increase in

the U.S. Term Loan Committed Amount pursuant to Section 4.4(b), as

applicable), with respect to the portion of the U.S. Term Loan initially

consisting of one or more Eurodollar Loans. Such Notice of Borrowing shall

be irrevocable and shall specify (i) that the funding of a U.S. Term Loan

is requested and (ii) whether the funding of the U.S. Term Loan shall be

comprised of U.S. Base Rate Loans, Eurodollar Loans or a combination

thereof, and if Eurodollar Loans are requested, the Interest Period(s)

therefor. If Airgas shall fail to deliver such Notice of Borrowing to the

U.S. Agent by 11:00 A.M. (Charlotte, North Carolina time) on the third

Business Day prior to the Closing Date (or the effective date of any

increase in the U.S. Term Loan Committed Amount pursuant to Section

4.4(b), as applicable), then the full amount of the U.S. Term Loan shall

be disbursed on the Closing Date (or on the

37

<PAGE>

effective date of any increase in the U.S. Term Loan Committed Amount

pursuant to Section 4.4(b), as applicable) as a U.S. Base Rate Loan. Each

U.S. Term Lender shall make its U.S. Term Loan Percentage of the U.S. Term

Loan available to the U.S. Agent for the account of Airgas by 1:00 P.M.

(Charlotte, North Carolina time) on the Closing Date (or on the effective

date of any increase in the U.S. Term Loan Committed Amount pursuant to

Section 4.4(b), as applicable) in U.S. Dollars and in funds immediately

available to the U.S. Agent.

(c) Minimum Amounts. Each Eurodollar Loan or U.S. Base Rate Loan

that is part of the U.S. Term Loan shall be in an aggregate principal

amount that is not less than $5,000,000 and integral multiples of

$1,000,000 (or the then remaining principal balance of the U.S. Term Loan,

if less).

(d) Repayment of U.S. Term Loan. Airgas promises to pay the

outstanding principal amount of the U.S. Term Loan in twenty (20)

consecutive quarterly installments as follows (as such installments may

hereafter be adjusted as a result of prepayments made pursuant to Section

4.3 or as the result of an increase in the amount of the U.S. Term Loan

Committed Amount pursuant to Section 4.4(b)), unless accelerated sooner

pursuant to Section 9.2:

ARTICLE III

CANADIAN DOLLAR CREDIT FACILITIES

3.1 CANADIAN REVOLVING LOANS.

(a) Canadian Revolving Commitment. Subject to the terms and conditions

hereof and in reliance upon the representations and warranties set forth herein,

each Canadian Lender severally and not jointly agrees to make available to each

Canadian Borrower, for its own account, such Canadian Lender's Canadian

Commitment Percentage of revolving credit loans requested by the Canadian

Borrowers in Canadian Dollars ("Canadian Revolving Loans") from time to time

from the Closing Date until the Termination Date, or such earlier date as the

Canadian Revolving Commitments shall have been terminated as provided herein for

the purposes hereinafter set forth; provided, however, that the sum of the

to the Canadian Agent for the account of the particular Canadian Borrower

by 1:00 P.M. (Toronto, Ontario time) on the date specified in the

applicable Notice of Borrowing in Canadian Dollars and in funds

immediately available to the Canadian Agent. Such borrowing will then be

made available to the particular Canadian Borrower by the Canadian Agent

in like funds as received by the Canadian Agent by (A) crediting the

account of such Canadian Borrower on the books of the Canadian Agent with

the amount of such funds or (B) wire transfer of such funds, in each case

in accordance with instructions provided to (and reasonably acceptable to)

the Canadian Agent by such Canadian Borrower

(c) Repayment. Each Canadian Borrower promises to pay the principal amount

of all Canadian Revolving Loans made to such Canadian Borrower in full on the

Termination Date.

(d) Interest. Subject to the provisions of Section 4.1, Canadian Revolving

Loans shall bear interest at a per annum rate equal to the Canadian Base Rate

each applicable Interest Payment Date (or at such other times as may be

specified herein).

3.2 CANADIAN SWINGLINE LOAN SUBFACILITY.

(a) Canadian Swingline Commitment. Subject to the terms and conditions set

forth herein, the Canadian Swingline Lender agrees, in reliance upon the

agreements of the other Canadian Lenders set forth in this Section 3.2, each

Canadian Borrower may, in its individual capacity, obtain revolving credit loans

in Canadian Dollars from the Canadian Swingline Lender, in its individual

capacity (each a "Canadian Swingline Loan" and, collectively, the "Canadian

Swingline Loans"), from time to time from the Closing Date until the Termination

Date (i) by written notice (or telephone notice promptly confirmed in writing)

from such Canadian Borrower (by its duly authorized officers or representatives)

to the Canadian Swingline Lender not later than 2:00 P.M. (Toronto, Canada time)

on the Business Day of the requested Canadian Swingline Loan advance (in which

case the Canadian Swingline Lender shall credit the funds requested to the

applicable Operating Account by 3:00 P.M. (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

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 Canadian Revolving Loans plus

the aggregate principal amount of outstanding Canadian Swingline Loans plus

Canadian LOC Obligations outstanding plus the BA Outstandings shall not exceed

the Canadian Revolving Committed Amount. Unless the Canadian Borrowers have made

prior arrangements with the Canadian Swingline Lender (including without

limitation by requesting a Canadian Revolving 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

Canadian Revolving 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

40

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 Canadian Revolving

Loan advance, in which case the Canadian Borrower shall be deemed to have

requested a Canadian Revolving 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 Canadian Revolving

Loan in the amount, in the manner and on the date specified in the preceding

sentence notwithstanding (I) the amount of such borrowing may not comply with

the minimum amount for advances of Canadian Revolving Loans otherwise required

hereunder, (II) whether any conditions specified in Section 5.2 are then

satisfied, (III) whether a Default or an Event of Default then exists, (IV)

failure of any such request or deemed request for a Canadian Revolving Loan to

be made by the time otherwise required hereunder, (V) whether the date of such

borrowing is a date on which Canadian Revolving Loans are otherwise permitted to

be made hereunder or (VI) any termination of the Commitments relating thereto

immediately prior to or contemporaneously with such borrowing.

(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 plus the Applicable Percentage; 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).
