          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 Revolving U.S. 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 2.1(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 Revolving U.S. 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 Revolving U.S. Committed Amount, if less).

               (iii) Advances. Each U.S. Lender will make its U.S.
          Commitment Percentage of each Revolving U.S. Loan borrowing
          available to the U.S. Agent for the account of Airgas as
          specified in Section 4.14, or in such other manner as the U.S.
          Agent may specify in writing, by 1:00 P.M. (Charlotte, North
          Carolina time) on the date specified in the applicable Notice of
          Borrowing in U.S. Dollars and in funds immediately available to
          the U.S. Agent. Such borrowing will then be made available to
          Airgas by the U.S. Agent by crediting the account of Airgas on
          the books of the main office of the U.S. Agent in Charlotte,
          North Carolina with the aggregate of the amounts made available
          to the U.S. Agent by the U.S. Lenders and in like funds as
          received by the U.S. Agent.

          (c) Repayment. Airgas promises to pay the principal amount of all
Revolving U.S. Loans in full on the Termination Date.

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

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

               (ii) Eurodollar Loans. During such periods as Revolving U.S.
          Loans shall be comprised in whole or in part of Eurodollar Loans,
          such Eurodollar Loans shall bear interest at a per annum rate
          equal to the Eurodollar Rate plus the Applicable Percentage.

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

          2.2      Competitive U.S. Loan Subfacility.

          (a) Competitive U.S. Loans. Subject to the terms and conditions
and relying upon the representations and warranties herein set forth,
Airgas may, from time to time from the Closing Date until the Termination
Date, request and each U.S. Lender may, in its sole discretion, agree to
make, Competitive U.S. Loans in U.S. Dollars to Airgas; provided, however,
that (i) the aggregate principal amount of outstanding Competitive U.S.
Loans shall not at any time exceed FIFTY MILLION U.S. DOLLARS
(U.S.$50,000,000) and (ii) the sum of the aggregate principal amount of
outstanding Revolving U.S. 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 at any time exceed the Revolving U.S. Committed Amount. Each
Competitive U.S. Loan shall be not less than U.S.$1,000,000 in the
aggregate and integral multiples of U.S.$500,000 in excess thereof (or the
remaining portion of the Revolving U.S. Committed Amount, if less).





          (b) Competitive U.S. Bid Requests. Airgas (by its duly authorized
officers or representatives) may solicit by making a written, telefax or
telephonic request to all of the U.S. Lenders for a Competitive U.S. Loan.
To be effective, such request must be received by each of the U.S. Lenders
by such time as determined by each such U.S. Lender in accordance with such
U.S. Lender's customary practices (in any event not to be later than 12:00
NOON (Charlotte, North Carolina time)) on the date of the requested
borrowing and must specify (i) that a Competitive U.S. Loan is requested,
(ii) the amount of such Competitive U.S. Loan and (iii) the Interest Period
for such Competitive U.S. Loan.

          (c) Competitive U.S. Bids. Upon receipt of a request by Airgas
for a Competitive U.S. Loan, each U.S. Lender may, in its sole discretion,
submit a Competitive U.S. Bid containing an offer to make a Competitive
U.S. Loan in an amount up to the amount specified in the related request
for Competitive U.S. Loans. Such Competitive U.S. Bid shall be submitted to
Airgas by telephone notice by such time as determined by such U.S. Lender
in accordance with such U.S. Lender's customary practices (in any event not
to be later than 1:00 P.M. (Charlotte, North Carolina time)) on the date of
the requested Competitive U.S. Loan. Competitive U.S. Bids so made shall be
irrevocable. Each Competitive U.S. Bid shall specify (i) the date of the
proposed Competitive U.S. Loan, (ii) the maximum and minimum principal
amounts of the Competitive U.S. Loan for which such offer is being made
(which may be for all or a part of (but not more than) the amount requested
by Airgas), (iii) the applicable Competitive U.S. Bid Rate, and (iv) the
applicable Interest Period.

          (d) Acceptance of Competitive U.S. Bids. Airgas (by its duly
authorized officers or representatives) may, before such time as determined
by the applicable U.S. Lender in accordance with such U.S. Lender's
customary practices (in any event until 2:00 P.M. (Charlotte, North
Carolina time)) on the date of the requested Competitive U.S. Loan, accept
any Competitive U.S. Bid by giving the applicable U.S. Lender and the U.S.
Agent telephone notice (immediately confirmed in writing) of (i) the U.S.
Lender or U.S. Lenders whose Competitive U.S. Bid(s) is/are accepted, (ii)
the principal amount of the Competitive U.S. Bid(s) so accepted and (iii)
the Interest Period of the Competitive U.S. Bid(s) so accepted. Airgas may
accept any Competitive U.S. Bid in whole or in part; provided, however,
that (a) the principal amount of each Competitive U.S. Loan may not exceed
the maximum amount offered in the Competitive U.S. Bid and may not be less
than the minimum amount offered in the Competitive U.S. Bid, (b) the
principal amount of each Competitive U.S. Loan may not exceed the total
amount requested pursuant to subsection (a) above, (c) Airgas shall not
accept a Competitive U.S. Bid made at a particular Competitive U.S. Bid
Rate if it has decided to reject a Competitive U.S. Bid made at a lower
Competitive U.S. Bid Rate and (d) if Airgas shall accept a Competitive U.S.
Bid or Bids made at a particular Competitive U.S. Bid Rate but the amount
of such Competitive U.S. Bid or Bids shall cause the total amount of
Competitive U.S. Bids to be accepted by Airgas to exceed the total amount
requested pursuant to subsection (a) above, then Airgas shall accept a
portion of such Competitive U.S. Bid or Bids in an amount equal to the
total amount requested pursuant to subsection (a) above less the amount of
other Competitive U.S. Bids accepted with respect to such request, which
acceptance, in the case of multiple Competitive U.S. Bids at the same
Competitive U.S. Bid Rate, shall be made pro rata in accordance with each
such Competitive U.S. Bid at such Competitive U.S. Bid Rate. Competitive
U.S. Bids so accepted by Airgas shall be irrevocable.

          (e) Funding of Competitive U.S. Loans. Upon acceptance by Airgas
pursuant to subsection (d) above of all or a portion of any U.S. Lender's
Competitive U.S. Bid, such U.S. Lender shall, before such time as
determined by such U.S. Lender in accordance with such U.S. Lender's
customary practices, on the date of the requested Competitive U.S. Loan,
make such Competitive U.S. Loan available to the U.S. Agent in Federal or
other immediately available funds. Upon receipt of such funds, the U.S.
Agent will promptly make such funds available to Airgas at Account No.
3750353729 maintained at the offices of Bank of America; provided, however,
that if on the date of such Competitive U.S. Loan Airgas is to repay all or
any part of an outstanding Revolving U.S. Loan, then the U.S. Agent shall
apply such Competitive U.S. Loan first to such repayment, and only an
amount equal to the excess (if any) of the amount borrowed over the amount
being repaid shall be made available to Airgas.

          (f) Repayment of Competitive U.S. Loans. Airgas promises to repay
to each U.S. Lender which has made a Competitive U.S. Loan on the last day
of the Interest Period for such Competitive U.S. Loan the then unpaid
principal amount of such Competitive U.S. Loan. Airgas may not prepay any
Competitive U.S. Loan unless such prepayment is accompanied by payment of
amounts specified in Section 4.11.





          (g) Interest. Airgas promises to pay interest to each U.S. Lender
on the unpaid principal amount of each Competitive U.S. Loan of such U.S.
Lender from and including the date of such Competitive U.S. Loan to but
excluding the stated maturity date thereof, at the applicable Competitive
U.S. Bid Rate for such Competitive U.S. Loan (computed on the basis of the
actual number of days elapsed over a year of 360 days). Interest on
Competitive U.S. Loans shall be payable in arrears on each applicable
Interest Payment Day (or at such other times as may be specified herein).

          (h) Limitation on Number of Competitive U.S. Loans. Airgas shall
not request a Competitive U.S. Loan if, assuming the maximum amount of
Competitive U.S. Loans so requested is borrowed as of the date of such
request, (i) the sum of the aggregate principal amount of outstanding
Revolving U.S. 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 would exceed the
aggregate Revolving U.S. Committed Amount and (ii) the sum of the aggregate
principal amount of outstanding Competitive U.S. Loans would exceed
U.S.$50,000,000.

          (i) Change in Procedures for Requesting Competitive U.S. Loans.
Airgas and the U.S. Lenders hereby agree that, notwithstanding any other
provision to the contrary contained in this Credit Agreement, upon mutual
agreement of the U.S. Agent and Airgas and written notice by the U.S. Agent
to the U.S. Lenders, all further requests by Airgas for Competitive U.S.
Loans shall be made by Airgas to the U.S. Lenders through the U.S. Agent in
accordance with such procedures as shall be prescribed by the U.S. Agent
and acceptable to Airgas and each U.S. Lender.

          2.3      U.S. Letter of Credit Subfacility.

          (a) Issuance. Subject to the terms and conditions hereof and of
the U.S. LOC Documents, if any, and any other terms and conditions which
the U.S. Issuing Lender may reasonably require, and in reliance upon the
agreements of the Credit Parties and U.S. Lenders set forth herein, the
U.S. Lenders will participate in the issuance by the U.S. Issuing Lender
from time to time of such U.S. Letters of Credit in U.S. Dollars from the
Closing Date until the Termination Date as Airgas may request, in a form
acceptable to the U.S. Issuing Lender; provided, however, that (i) the U.S.
LOC Obligations outstanding shall not at any time exceed FIFTY-FIVE MILLION
U.S. DOLLARS (U.S.$55,000,000) (the "U.S. LOC Committed Amount") and (ii)
the sum of the aggregate principal amount of outstanding Revolving U.S.
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 at any time exceed
the aggregate Revolving U.S. Committed Amount. No U.S. Letter of Credit
shall (x) have an original expiry date more than one year from the date of
issuance (provided that such U.S. Letter of Credit may contain customary
"evergreen" provisions pursuant to which the expiry date is automatically
extended by a specific time period unless the U.S. Issuing Lender gives
notice of non-renewal to the beneficiary of such U.S. Letter of Credit at
least a specified time period prior to the expiry date then in effect), or
(y) as originally issued or as extended, have an expiry date extending
beyond the Termination Date. The U.S. Issuing Lender shall be under no
obligation to issue any U.S. Letter of Credit if the issuance of such U.S.
Letter of Credit would violate any applicable Requirement of Law or any
policy of the U.S. Issuing Lender. Each U.S. Letter of Credit shall comply
with the related U.S. LOC Documents. The issuance and expiry dates of each
U.S. Letter of Credit shall be a Business Day.

          (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 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. 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. 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. Commitment Percentages of the U.S.
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. 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. 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.
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.
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 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.

          (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 (the "UCP") or the International Standby
Practices 1998 (the "ISP98"), in either case as published as of the date of
issue by the International Chamber of Commerce, in which case the UCP or
the ISP98, as applicable, 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 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.

          (a) U.S. Swingline Commitment. Subject to the terms and
conditions hereof and in reliance upon the representations and warranties
herein set forth, 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 TWENTY MILLION U.S. DOLLARS (U.S.$20,000,000)
(the "U.S. Swingline Committed Amount"), and (ii) the aggregate principal
amount of outstanding Revolving U.S. 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 Revolving U.S. 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 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 U.S.$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. 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 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. 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
          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.

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


                                 SECTION 3

                     Canadian Dollar CREDIT FACILITIES

          3.1      Revolving Canadian Loans.

          (a) Revolving Canadian 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 ("Revolving
Canadian Loans") from time to time from the Closing Date until the
Termination Date, or such earlier date as the Revolving Canadian
Commitments shall have been terminated as provided herein for the purposes
hereinafter set forth; provided, however, that the sum of the aggregate
principal amount of outstanding Revolving Canadian Loans shall not exceed
FIFTY MILLION Canadian DollarS (C$50,000,000) (as such aggregate maximum
amount may be increased or reduced from time to time as provided in Section
4.4, the "Revolving Canadian Committed Amount"); provided, further, (i)
with regard to each Canadian Lender individually, outstanding Revolving
Canadian Loans of such Canadian Lender plus the Participation Interests in
Canadian LOC Obligations of such Canadian Lender plus the BA Outstandings
of such Canadian Lender shall not exceed such Canadian Lender's Canadian
Commitment Percentage of the Revolving Canadian Committed Amount and (ii)
with regard to the Canadian Lenders collectively, 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. Revolving Canadian Loans hereunder may
be repaid and reborrowed in accordance with the provisions hereof.

          (b) Revolving Canadian Loan Borrowings.

               (i) Notice of Borrowing. Each Canadian Borrower (by its duly
          authorized officers or representatives) shall request a Revolving
          Canadian Loan borrowing by Notice of Borrowing (or telephone
          notice promptly confirmed by delivery of a Notice of Borrowing)
          to the Canadian Agent not later than 11:00 A.M. (Toronto, Ontario
          time) on the Business Day prior to the date of the requested
          borrowing. Each such request for borrowing shall be irrevocable
          and shall specify (A) that a Revolving Canadian Loan is
          requested, (B) the date of the requested borrowing (which shall
          be a Business Day) and (C) the aggregate principal amount to be
          borrowed. The Canadian Agent shall give notice to each affected
          Canadian Lender promptly upon receipt of each Notice of Borrowing
          pursuant to this Section 3.1(b)(i), specifying the contents
          thereof and each such Canadian Lender's share of any borrowing to
          be made pursuant thereto.

               (ii) Minimum Amounts. Each Revolving Canadian Loan shall be
          in a minimum aggregate principal amount of C$1,500,000 and
          integral multiples of C$100,000 in excess thereof (or the
          remaining amount of the Revolving Canadian Committed Amount, if
          less).

               (iii) Advances. Each Canadian Lender will make its Canadian
          Commitment Percentage of each Revolving Canadian Loan borrowing
          available to the Canadian Agent for the account of the particular
          Canadian Borrower as specified in Section 4.14, or in such other
          manner as the Canadian Agent may specify in writing, 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 by crediting the account of such Canadian Borrower on the
          books of the main office of the Canadian Agent in Toronto,
          Ontario with the aggregate of the amounts made available to the
          Canadian Agent by the Canadian Lenders and in like funds as
          received by the Canadian Agent.





          (c) Repayment. Each Canadian Borrower promises to pay the
principal amount of all Revolving Canadian Loans made to such Canadian
Borrower in full on the Termination Date.

          (d) Interest. Subject to the provisions of Section 4.1, Revolving
Canadian Loans shall bear interest at a per annum rate equal to the
Canadian Base Rate plus the Applicable Percentage. Each Canadian Borrower
promises to pay interest on Revolving Canadian Loans made to such Canadian
Borrower monthly in arrears on 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 hereof and in reliance upon the representations and warranties
herein set forth, 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 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 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).

          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, and in reliance
upon the agreements of the Credit Parties and Canadian Lenders set forth
herein, 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 (provided that such Canadian Letter of Credit may
contain customary "evergreen" provisions pursuant to which the expiry date
is automatically extended by a specific time period unless the Canadian
Issuing Lender gives notice of non-renewal to the beneficiary of such
Canadian Letter of Credit at least a specified time period prior to the
expiry date then in effect), or (y) as originally issued or as extended,
have an expiry date extending beyond the Termination Date. The Canadian
Issuing Lender shall be under no obligation to issue any Canadian Letter of
Credit if the issuance of such Canadian Letter of Credit would violate any
applicable Requirement of Law or any policy of the Canadian Issuing Lender.
Each Canadian Letter of Credit shall comply with the related Canadian LOC
Documents. The issuance and expiry dates 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
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 the Applicable Percentage 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 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 the applicable Canadian
Borrower 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 Lender may have
the Canadian Letters of Credit be subject to The Uniform Customs and
Practice for Documentary Credits (the "UCP") or the International Standby
Practices 1998 (the "ISP98"), in either case as published as of the date of
issue by the International Chamber of Commerce, in which case the UCP or
the ISP98, as applicable, may be 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 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.

          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. Each 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 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) To facilitate acceptance of drafts, each Canadian Borrower
hereby appoints each Canadian Lender as its attorney to sign and endorse on
its behalf (in accordance with a request under section 3.4(a) above), in
handwriting or by facsimile or mechanical signature as and when deemed
necessary by such Canadian Lender, blank drafts in the form requested by
such Canadian Lender. In this respect, it is each Canadian Lender's
responsibility to maintain an adequate supply of such blank forms of draft
for acceptance under this Credit Agreement. All such drafts signed and/or
endorsed by a Canadian Lender on behalf of a Canadian Borrower pursuant to
such a request shall be deemed to have been presented by such Canadian
Borrower for acceptance and shall bind such Canadian Borrower as fully and
effectually as if signed in the handwriting of and duly issued by the
proper signing officers of such Canadian Borrower. Notwithstanding that any
person whose signature appears on any Bankers' Acceptance may no longer be
an authorized signatory for any Canadian Lender or Canadian Borrower at the
date of issuance of a Bankers' Acceptance, such signature shall
nevertheless be valid and sufficient for all purposes as if such authority
had remained in force at the time of such issuance and any such Bankers'
Acceptance so signed shall be binding on the applicable Canadian Borrower.
Each Canadian Lender shall maintain a record with respect to Bankers'
Acceptances (A) accepted and purchased by it hereunder, and (B) cancelled
at their respective maturities. On request by or on behalf of a Canadian
Borrower, a Canadian Lender shall cancel all forms of Bankers' Acceptance
which have been pre-signed or pre-endorsed on behalf of such Canadian
Borrower and which are held by such Canadian Lender and are not required to
be issued in accordance with such Canadian Borrower's request(s). Each
Canadian Borrower hereby confirms that each Canadian Lender shall be
entitled to rely upon instructions provided by Airgas regarding the
completion of drafts 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.

          (c) Transition.

          The parties hereto acknowledge that as at the Closing Date,
certain Bankers' Acceptances ("Old Bas") are outstanding which were issued
prior to such date and mature after such date, and agree that the following
provisions shall be applicable to Old BAs:

          (i) Any Old BA accepted by a Canadian Lender (as defined in the
Existing Credit Agreement) that is not a party to this Credit Agreement (an
"Old Lender") shall be deemed for purposes of this Credit Agreement to have
been issued under this Credit Agreement; without limiting the generality of
the foregoing, the Face Amount of any such Old BA shall, so long as it
remains outstanding, be included in the BA Outstandings hereunder.





          (ii) Any amount paid by a Canadian Lender hereunder to indemnify
an Old Lender as acceptor of any Old BA by reason of the failure of the
applicable Canadian Borrower to comply with Section 3.4(b)(iv) above shall
be subject to the same terms as are applicable to a Canadian Base Rate Loan
made by such Canadian Lender, but be payable on demand, and the obligation
of the applicable Canadian Borrower to pay any such amount shall be a
Canadian Obligation.

          (iii) If and to the extent that the Applicable Percentage of a
Canadian Lender hereunder differs from the Applicable Percentage of such
Canadian Lender (in its capacity as a Canadian Lender under the Existing
Credit Agreement), the liability and entitlement of such Canadian Lender in
respect of any Old BA shall be determined by its Applicable Percentage
hereunder rather than by its Applicable Percentage under the Existing
Credit Agreement, and the Canadian Lenders shall make such payments to one
another as shall be necessary to give effect to each such change in
Applicable Percentage, including without limitation the calculation of the
Acceptance Fee to which such Canadian Lender is entitled for the period
from (but excluding) the Closing Date to (and including) the maturity of
the Old BA in respect of which an Acceptance Fee was paid upon issuance.

          3.5      Removal of a Canadian Borrower.

          Airgas may at any time request that any Canadian Borrower
hereunder cease to be a Canadian Borrower by delivering to the Canadian
Agent (which shall promptly deliver counterparts thereof to each Canadian
Lender) a written notice to such effect. Such Canadian Borrower shall cease
to be a Canadian Borrower hereunder on the later to occur of (i) the date
the Canadian Agent receives such request, and (ii) the date on which (A)
such Canadian Borrower has paid all of the Canadian Obligations owing by
such Canadian Borrower, and (B) no Canadian Letter of Credit issued at the
request of such Canadian Borrower remains outstanding.

          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.

          (a) Payment Defaults. Upon the occurrence, and during the
continuance, of an Event of Default of the type described in Section
9.1(a), 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 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 plus the Applicable Percentage).

          (b) Non-Payment Defaults. Except as provided in subsection (a)
above, during the continuance of any Event of Default for a period of more
than 30 days from the date Airgas receives notice thereof from the U.S.
Agent, the principal of and, to the extent permitted by law, interest on
the Loans and any other amounts owing hereunder or under the other Credit
Documents shall, at the discretion of the Required Lenders, bear interest,
payable on demand, at a per annum rate 2% greater than 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
plus the Applicable Percentage).





         4.2      Extension and Conversion.

          (a) Airgas. Airgas shall have the option, on any Business Day, to
extend existing Revolving U.S 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) 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) and 3.1(b)(ii),
(iii) 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), (iv) 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 (v) 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. In the event Airgas fails to request
extension or conversion of any Eurodollar Loan in accordance with this
Section, or any such conversion or extension is not permitted or required
by this Section, then such Eurodollar Loan shall be automatically converted
into a U.S. Base Rate Loan at the end of the Interest Period applicable
thereto. The U.S. Agent shall give each U.S. Lender notice as promptly as
practicable of any such proposed extension or conversion affecting any
Loan.

          (b) Canadian Borrowers. A Canadian Borrower shall have the
option, on any Business Day, to convert a Canadian Base Rate Loan into a
Bankers' Acceptance, to continue a maturing Bankers' Acceptance in
accordance with Section 3.4 or to convert a maturing Bankers' Acceptance
into a Canadian Base Rate Loan; provided, however, (i) each such
continuation or conversion must be requested by such Canadian Borrower
pursuant to a written Notice of Extension/Conversion, in the form of
Schedule 4.2, in compliance with the terms set forth below and (ii) such
Canadian Borrower must comply with all the requirements of Section 3.4, and
(iii) failure by such Canadian Borrower to properly continue a Bankers'
Acceptance shall be deemed a conversion to a Canadian Base Rate Loan. Each
continuation or conversion must be requested by such Canadian Borrower no
later than 10:00 a.m., Toronto, Ontario time, on (A) the date of a
requested conversion of a Bankers' Acceptance to a Canadian Base Rate Loan
or (B) the third Business Day prior to the date of a requested continuation
of a Bankers' Acceptance or conversion of a Canadian Base Rate Loan to a
Bankers' Acceptance, in each case pursuant to a written Notice of
Extension/Conversion submitted to the Canadian Agent which shall set forth
(x) whether the Loans to be continued or converted are Revolving Canadian
Loans, (y) whether the Canadian Borrower wishes to continue or convert such
Loans and (z) if the request is to continue a Bankers' Acceptance or
convert a Canadian Base Rate Loan to a Bankers' Acceptance, the maturity
date applicable thereto.


          4.3      Prepayments.

          (a) Voluntary Prepayments. Loans may be prepaid in whole or in
part from time to time, subject to Section 4.11, but otherwise without
premium or penalty; provided, however, that (i) Eurodollar Loans and
Competitive U.S. Loans may only be prepaid on three Business Days' prior
written notice to the U.S. Agent, and specifying the applicable Loans to be
prepaid; (ii) any prepayment of Eurodollar Loans, Competitive U.S. Loans or
Quoted Rate U.S. Swingline Loans will be subject to Section 4.11; (iii) any
portion of the Revolving Canadian Committed Amount represented by a
Bankers' Acceptance may not be prepaid prior to the maturity of such
Bankers' Acceptance; (iv) each such partial prepayment of Loans shall be
(A) in the case of Revolving U.S. Loans, in a minimum principal amount of
U.S.$5,000,000 and integral multiples of U.S.$1,000,000 in excess thereof,
(B) in the case of Revolving Canadian Loans, in a minimum principal amount
of C$1,500,000 and integral multiples of C$100,000 in excess thereof and
(C) in the case of U.S. Swingline Loans, in a minimum principal amount of
U.S.$100,000 and integral multiples thereof. Subject to the foregoing
terms, amounts prepaid under this Section 4.3(a) shall be applied as the
applicable Borrower may elect.





         (b)      Mandatory Prepayments.

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

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

               (iii) Asset Dispositions. Immediately upon the occurrence of
          any Asset Disposition Prepayment Event, the applicable Borrower
          shall prepay the Loans in an aggregate amount equal to 100% of
          the Net Cash Proceeds of the related Asset Disposition not
          applied (or caused to be applied) by the Credit Parties during
          the related Application Period to make Eligible Reinvestments as
          contemplated by the terms of Section 8.4(b)(v) (such prepayment
          to be applied as set forth in clause (v) below).

               (iv) Debt Issuances. Within three days following the
          occurrence of a Debt Issuance Prepayment Event, the applicable
          Borrower shall prepay the Loans in an aggregate amount equal to
          100% of the Net Cash Proceeds of the related Debt Issuance (such
          prepayment to be applied as set forth in clause (v) below).

               (v) Application of Certain Mandatory Prepayments.

                    (A) Asset Dispositions and Debt Issuances by the U.S.
               Credit Parties. All amounts required to be paid by the U.S.
               Credit Parties pursuant to Section 4.3(b)(iii) or (iv) shall
               be applied first to the U.S. Swingline Loans, second to the
               Revolving U.S. Loans, third to the Competitive U.S. Loans
               (and, after all Revolving U.S. Loans, Competitive U.S. Loans
               and U.S. Swingline Loans have been repaid, to the U.S. Agent
               additional cash in respect of U.S. LOC Obligations, to be
               held by the U.S. Agent, for the benefit of the Lenders, in a
               cash collateral account) and fourth to the Canadian
               Obligations of the types described in and in the manner
               provided in subclause (B) below. To the extent the aggregate
               U.S. Dollar Amount of all prepayments required to be made
               pursuant to Sections 4.3(b)(iii) and 4.3(b)(iv) exceeds
               U.S.$75,000,000, the Revolving U.S. Committed Amount shall
               be permanently reduced in an amount equal to the U.S. Dollar
               Amount of all additional amounts applied pursuant to this
               clause (A) and clause (B) below). Without limiting the
               foregoing sentence, to the extent that any obligation to
               make a mandatory prepayment of the loans arises from an
               Asset Disposition Prepayment Event of the type described in
               clause (ii) of the definition thereof, the Revolving U.S.
               Committed Amount shall be permanently reduced in an amount
               equal to the U.S. Dollar Amount of such prepayment.

                    (B) Asset Dispositions and Debt Issuances by the
               Canadian Credit Parties. All amounts required to be paid by
               the Canadian Credit Parties pursuant to Section 4.3(b)(iii)
               or (iv) shall be applied first to the Canadian Swingline
               Loans, second to the Revolving Canadian Loans, third to the
               BA Outstandings in direct order of maturities (and, after
               all Revolving Canadian Loans, Canadian Swingline Loans and
               BA Outstandings have been repaid, to the Canadian Agent
               additional cash in respect of Canadian LOC





               Obligations, to be held by the Canadian Agent, for the
               benefit of the Lenders, in a cash collateral account) and
               fourth to the remaining Credit Party Obligations of the
               types described in and in the manner provided in subclause
               (A) above. To the extent the aggregate U.S. Dollar Amount of
               all prepayments required to be made pursuant to Sections
               4.3(b)(iii) and 4.3(b)(iv) exceeds U.S.$75,000,000, the
               Revolving Canadian Committed Amount shall be permanently
               reduced in an amount equal to the Canadian Dollar Equivalent
               of all additional amounts applied pursuant to this
               clause (B) and clause (A) above). Without limiting the
               foregoing sentence, to the extent that any obligation to
               make a mandatory prepayment of the loans arises from an
               Asset Disposition Prepayment Event of the type described in
               clause (ii) of the definition thereof, the Revolving
               Canadian Committed Amount shall be permanently reduced in an
               amount equal to the Canadian Dollar Equivalent of such
               prepayment.

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

               (vi) Prepayment Account. If Airgas is required to make a
          mandatory prepayment of Eurodollar Loans under this
          Section 4.3(b), Airgas shall have the right, in lieu of making
          such prepayment in full, to deposit an amount equal to such
          mandatory prepayment with the U.S. Agent in a cash collateral
          account maintained (pursuant to documentation reasonably
          satisfactory to U.S. Agent) by and in the sole dominion and
          control of U.S. Agent. Any amounts so deposited shall be held by
          the U.S. Agent as collateral for the prepayment of such
          Eurodollar Loans and shall be applied to the prepayment of the
          applicable Eurodollar Loans at the end of the current Interest
          Periods applicable thereto. At the request of Airgas, amounts so
          deposited shall be invested by the U.S. Agent in Cash Equivalents
          maturing prior to the date or dates on which it is anticipated
          that such amounts will be applied to prepay such Eurodollar
          Loans; any interest earned on such Cash Equivalents will be for
          the account of Airgas and Airgas will deposit with the U.S. Agent
          the amount of any loss on any such Cash Equivalents to the extent
          necessary in order that the amount of the prepayment to be made
          with the deposited amounts may not be reduced.

          4.4      Termination and Reduction of Commitments; Increase of
          Commitments.

          (a) Voluntary Reductions; Terminations.

               (i) Airgas may from time to time permanently reduce or
          terminate the Revolving U.S. Committed Amount in whole or in part
          (in minimum aggregate amounts of U.S.$5,000,000 or in integral
          multiples of U.S.$1,000,000 in excess thereof (or, if less, the
          full remaining amount of the Revolving U.S. Committed Amount))
          upon five Business Days' prior written notice to the U.S. Agent.
          The Revolving U.S. Commitments of the U.S. Lenders, the U.S.
          Swingline Commitment of the U.S. Swingline Lender and the U.S.

          terminate on the Termination Date;

               (ii) Airgas or the Canadian Borrowers may from time to time
          permanently reduce or terminate the Revolving Canadian Committed
          Amount in whole or in part (in minimum aggregate amounts of
          C$1,500,000 or in integral multiples of C$100,000 in excess
          thereof (or, if less, the full remaining amount of the Revolving
          Canadian Committed Amount)) upon five Business Days' prior
          written notice to the U.S. Agent and the Canadian Agent. The
          Revolving Canadian Commitments of the Canadian Lenders, the
          Canadian Swingline Commitment of the Canadian Swingline Lender
          and the Canadian LOC Commitment of the Canadian Issuing Lender
          shall automatically terminate on the Termination Date;

provided, however, no such termination or reduction shall be made which
would cause (i) the aggregate principal amount of outstanding Revolving
U.S. 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 to exceed the
Revolving U.S. Committed Amount or (ii) 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 to exceed the Revolving Canadian
Committed Amount unless,





concurrently with such termination or reduction, the respective Loans are
repaid to the extent necessary to eliminate such excess. The U.S. Agent
shall promptly notify each affected Lender of receipt by such U.S. Agent of
any notice pursuant to this Section 4.4(a).

          (b) Unused Fees.

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

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

          (c) Mandatory Reductions. The Revolving U.S. Committed Amount and
the Revolving Canadian Committed Amount, as applicable, automatically shall
be permanently reduced from time to time in accordance with the terms of
Section 4.3(b)(v).

          (d) Increase in Commitments. The Borrowers shall have the right
upon at least fifteen (15) Business Days' prior written notice to the U.S.
Agent to increase the Revolving U.S. Committed Amount and/or the Revolving
Canadian Committed Amount by the U.S. Dollar Amount of up to
U.S.$100,000,000 (or the Canadian Dollar Equivalent) in the aggregate, in
one or more increases, at any time and from time to time on or after the
Closing Date, subject, however, in any such case, to satisfaction of the
following conditions precedent:

               (i) no Default or Event of Default has occurred and is
          continuing on the date on which such increase is to become
          effective;

               (ii) the representations and warranties set forth in Section
          6 of this Credit Agreement shall be true and correct in all
          material respects on and as of the date on which such increase is
          to become effective;

               (iii) such increase shall be (A) in respect of any increase
          in the Revolving U.S. Committed Amount, an integral multiple of
          U.S.$1,000,000 and shall in no event be less than U.S.$5,000,000
          and (B) in respect of any increase in the Revolving Canadian
          Committed Amount, an integral multiple of the Canadian Dollar
          Equivalent of U.S.$1,000,000 and shall in no event be less than
          the Canadian Dollar Equivalent of U.S.$5,000,000;

               (iv) such requested increase shall be effective on such date
          only to the extent that, on or before such date, (A) the U.S.
          Agent shall have received and accepted a corresponding amount of
          Additional Commitment(s) pursuant to a commitment letter(s)
          acceptable to the U.S. Agent from one or more lenders acceptable
          to the U.S. Agent and, with respect to any lender that is not at
          such time a Lender hereunder, Airgas and (B) each such lender has
          executed an agreement in the form of Schedule 4.4 hereto (each
          such agreement a "New Commitment Agreement"), accepted in writing
          therein by the U.S. Agent and, with respect to any lender that is
          not at such time a Lender hereunder, Airgas, with respect to the
          Additional Commitment of such lender; and

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

          4.6      Capital Adequacy.

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





          4.7      Inability To Determine Interest Rate.

          (a) If prior to the first day of any Interest Period, the U.S.
Agent shall have determined (which determination shall be conclusive and
binding upon Airgas) that, by reason of circumstances affecting the
relevant market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period, the U.S. Agent
shall give telecopy or telephonic notice thereof to Airgas and the U.S.
Lenders as soon as practicable thereafter. If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest
Period shall be made as U.S. Base Rate Loans and (b) any Loans that were to
have been converted on the first day of such Interest Period to or
continued as Eurodollar Loans shall be converted to or continued as U.S.
Base Rate Loans. Until such notice has been withdrawn by the U.S. Agent, no
further Eurodollar Loans shall be made or continued as such, nor shall
Airgas have the right to convert U.S. Base Rate Loans to Eurodollar Loans.

          (b) If the Canadian Agent determines in good faith, which
determination shall be final, conclusive and binding upon the Canadian
Borrowers absent manifest error, and notifies the Canadian Borrowers and
each of the Canadian Lenders that, by reason of circumstances affecting the
money market (i) there is no market for Bankers' Acceptances; or (ii) the
demand for Bankers' Acceptances is insufficient to allow the sale or
trading of the Bankers' Acceptances created and purchased hereunder, then,

               (A) the right of the Canadian Borrowers to request a
          borrowing by way of Bankers' Acceptances shall be suspended until
          the Canadian Agent determines in good faith that the
          circumstances causing such suspension no longer exist and the
          Canadian Agent so notifies the Canadian Borrowers; and

               (B) any notice of requested Bankers' Acceptances which is
          outstanding shall be canceled and the Bankers' Acceptance
          requested therein shall not be made.

          (c) The Canadian Agent shall promptly notify the Canadian
Borrowers of the suspension of the Canadian Borrowers' right to request a
Bankers' Acceptance and of the termination of any such suspension.

         4.8      Illegality.

          Notwithstanding any other provision herein, if the adoption of or
any change in any Requirement of Law or in the interpretation or
application thereof occurring after the Closing Date shall make it unlawful
for any U.S. Lender to make or maintain Eurodollar Loans as contemplated by
this Credit Agreement, (a) such Lender shall promptly give written notice
of such circumstances to Airgas and the U.S. Agent (which notice shall be
withdrawn whenever such circumstances no longer exist), (b) the commitment
of such Lender hereunder to make Eurodollar Loans, continue Eurodollar
Loans as such and convert a U.S. Base Rate Loan to Eurodollar Loans shall
forthwith be canceled and, until such time as it shall no longer be
unlawful for such Lender to make or maintain Eurodollar Loans, such Lender
shall then have a commitment only to make a U.S. Base Rate Loan when a
Eurodollar Loan is requested and (c) such Lender's Loans then outstanding
as Eurodollar Loans, if any, shall be converted automatically to U.S. Base
Rate Loans on the respective last days of the then current Interest Periods
with respect to such Loans or within such earlier period as required by
law. If any such conversion of a 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 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 Borrowers from such Lender, through an Agent, in accordance
herewith, the Borrowers shall be obligated to promptly pay such Lender,
upon its demand, any additional amounts necessary to compensate such Lender
for such increased cost or reduced amount receivable, provided that, in any
such case, 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 Borrowers shall be
conclusive and binding on the parties hereto in the absence of manifest
error. Each Lender agrees that it will promptly refund any amounts received
by it pursuant to this Section 4.9 that were erroneously billed to the
Borrowers, together with interest thereon at the Base Rate. This covenant
shall survive the termination of this Credit Agreement and the payment of
the Loans and all other amounts payable hereunder.

          4.10     Taxes.

          (a) Except as provided below in this subsection, all payments
made by the Credit Parties under this Credit Agreement shall be made free
and clear of, and without deduction or withholding for or on account of,
any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter
imposed, levied, collected, withheld or assessed by any court, or
governmental body, agency or other official, excluding 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. 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, (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, 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
Borrowers 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 4.10 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 to such Lender, deliver to Airgas and the
          U.S. Agent two (2) duly completed copies of United States
          Internal Revenue Service Form W-8BEN or W-8ECI, or successor
          applicable form, as the case may be, certifying that it is
          entitled to receive payments under this Credit Agreement without
          deduction or withholding of any United States federal income
          taxes;

                    (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-8BEN,
          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 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;

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 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, each
          payment or prepayment of principal in respect of any Revolving
          U.S. 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 reimbursement obligations arising from drawings
          under U.S. Letters of Credit, each payment of the Unused
          Revolving U.S Commitment Fee, 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
          and each conversion or extension of any Revolving U.S. 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. 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 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 Borrower(s) 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 the
United States Bankruptcy 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 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.

          (a) Place, Manner and Currency of Payments. 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 condition or deduction for any counterclaim,
defense, recoupment or setoff 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 condition or
deduction for any counterclaim, defense, recoupment or setoff 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.

          (b) Allocation of Payments from U.S. Credit Parties
After-Acceleration. Notwithstanding any other provisions of this Credit
Agreement to the contrary, after acceleration of the Credit Party
Obligations pursuant to Section 9.2 and after taking into account the
application of the amounts collected or received from the Canadian Credit
Parties as provided in Section 4.14(c), all amounts collected or received
by the Agents or any Lender from the U.S. Credit Parties on account of the
Credit Party Obligations or any other amounts outstanding under any of the
Credit Documents or in respect of the Collateral pledged by the U.S. Credit
Parties in support of the Credit Party Obligations shall be paid over or
delivered as follows:

               FIRST, to the payment of all reasonable out-of-pocket costs
          and expenses (including without limitation reasonable attorneys'
          fees) of the U.S. Agent in connection with enforcing the rights
          of the Lenders under the Credit Documents and any protective
          advances made by the U.S. Agent with respect to the Collateral
          under or pursuant to the terms of the Collateral Documents;

               SECOND, to the payment of any fees owed to the U.S. Agent;

               THIRD, to the payment of all reasonable out-of-pocket costs
          and expenses (including without limitation, reasonable attorneys'
          fees) of each of the U.S. Lenders in connection with enforcing
          its rights under the Credit Documents or otherwise with respect
          to the Credit Party Obligations (other than the Canadian
          Obligations) owing to such U.S. Lender;

               FOURTH, to the payment of all of the Credit Party
          Obligations (other than the Canadian Obligations) consisting of
          accrued fees and interest;

               FIFTH, to the payment of the outstanding principal amount of
          the Credit Party Obligations (other than the Canadian
          Obligations) (including the payment or cash collateralization of
          the outstanding U.S. LOC Obligations);

               SIXTH, to all other Credit Party Obligations (other than the
          Canadian Obligations) and other obligations which shall have
          become due and payable under the Credit Documents or otherwise
          and not repaid pursuant to clauses "FIRST" through "FIFTH" above;
          and

               SEVENTH, to the payment of the surplus, if any, to the
          payment of the Canadian Obligations in accordance with Section

In carrying out the foregoing, (i) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next

Loans and U.S. LOC Obligations) of amounts available to be applied pursuant

Section 4.14(b).

          (c) Allocation of Payments from Canadian Credit Parties After

to the contrary, after acceleration of the Credit Party Obligations
pursuant to Section 9.2, all amounts collected or received by the Agents or
any Lender on account of the Canadian Obligations or any other amounts
outstanding under any of the Credit Documents or in respect of the
Collateral pledged by the Canadian Credit Parties and by Airgas in support
of the Canadian Obligations shall be paid over or delivered as follows:

               FIRST, to the payment of all reasonable out-of-pocket costs
          and expenses (including without limitation reasonable attorneys'
          fees) of the U.S. Agent in connection with enforcing the rights
          of the Lenders under the Credit Documents and any protective
          advances made by the U.S. Agent with respect to the Collateral

          respect to the Canadian Obligations owing to such Canadian
          Lender;

               FOURTH, to the payment of all of the Canadian Obligations
          consisting of accrued fees and interest;

               FIFTH, to the payment of the outstanding principal amount of

               SIXTH, to all other Canadian Obligations and other
          obligations which shall have become due and payable under the
          Credit Documents or otherwise and not repaid pursuant to clauses
          "FIRST" through "FIFTH" above; and

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

In carrying out the foregoing, (i) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; (ii) each of the Canadian Lenders shall receive an

Canadian Loans and Canadian LOC Obligations) of amounts available to be
applied pursuant to clauses "THIRD", "FOURTH", "FIFTH" and "SIXTH" above;
and (iii) to the extent that any amounts available for distribution
pursuant to clause "FIFTH" above are attributable to the issued but undrawn
amount of outstanding Canadian Letters of Credit, such amounts shall be
held by the Canadian Agent in a cash collateral account and applied
(A) first, to reimburse the Canadian Issuing Lender from time to time for
any drawings under such Canadian Letters of Credit and (B) then, following
the expiration of all Canadian Letters of Credit, to all other obligations
of the types described in clauses "FIFTH" and "SIXTH" above in the manner
provided in this Section 4.14(c).

                                   SECTION 6

                        REPRESENTATIONS AND WARRANTIES

     Each Credit Party hereby represents to the Agents and each Lender
that:

     6.1 Financial Condition.

     (a) The audited consolidated balance sheet of the Consolidated
Parties, and the related consolidated statements of earnings and statements
of cash flows, as of March 31, 2001 have heretofore been furnished to each
Lender. Such financial statements (including the notes thereto) (i) have
been audited by KPMG Peat Marwick, (ii) have been prepared in accordance
with GAAP consistently applied throughout the periods covered thereby and
(iii) present fairly (on the basis disclosed in the footnotes to such
financial statements) the consolidated financial condition, results of
operations and cash flows of the Consolidated Parties as of such date and
for such periods. The unaudited interim balance sheets of the Consolidated
Parties as at the end of, and the related unaudited interim statements of
earnings and of cash flows for, each quarterly period ended after March 31,
2001 and prior to the Closing Date have heretofore been furnished to each
Lender. Such interim financial statements for each such quarterly period,
(i) have been prepared in accordance with GAAP consistently applied
throughout the periods covered thereby and (ii) present fairly (on the
basis disclosed in the footnotes to such financial statements) the
consolidated financial condition, results of operations and cash flows of
the Consolidated Parties as of such date and for such periods. During the
period from March 31, 2001 to and including the Closing Date, there has
been no sale, transfer or other disposition by the Consolidated Parties of
any material part of the business or property of the Consolidated Parties,
taken as a whole, and there has been no Acquisition, in each case, which,
is not reflected in the foregoing financial statements or in the notes
thereto or has not otherwise been disclosed in writing to the Agents on or
prior to the Closing Date.

     (b) The projections of profit and loss statements, balance sheets and
cash flow reports for the Consolidated Parties on a consolidated basis for
fiscal year 2001, copies of which have heretofore been furnished to each
Lender, are based upon reasonable assumptions made known to the Lenders and
upon information not known to be incorrect or misleading in any material
respect.

     6.2 No Change.

     Since March 31, 2001, there has been no development or event relating
to or affecting the Consolidated Parties which has had or would be
reasonably expected to have a Material Adverse Effect.

     6.3 Organization; Existence; Compliance with Law.

     Each Consolidated Party (a) is a corporation duly organized, validly
existing and is in good standing under the laws of the jurisdiction of its
incorporation or organization, (b) has the corporate or other necessary
power and authority, and the legal right, to own and operate its property,
to lease the property it operates as lessee and to conduct the business in
which it is currently engaged, (c) is duly qualified as a foreign entity
and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification, other than in such jurisdictions where the
failure to be so qualified and in good standing would not be reasonably
expected to have a Material Adverse Effect, and (d) is in compliance with
all material Requirements of Law.

     6.4 Power; Authorization; Enforceable Obligations.

     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 (other than
those arising pursuant to the Collateral Documents) 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.

     Except as disclosed and described in Schedule 6.6 attached hereto, no
litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the best knowledge of the Credit
Parties, threatened by or against the Consolidated Parties or against any
of their respective properties or revenues which (a) relates to any of the
Credit Documents or any of the transactions contemplated hereby or thereby
or (b) would be reasonably expected to have a Material Adverse Effect.

     6.7 No Default.

     No Consolidated Party is in default under or with respect to any of
its contractual obligations in excess of U.S.$10,000,000 in any respect
which would be reasonably expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

     6.8 Ownership of Property; Liens.

     Each Consolidated Party has good record and marketable title in fee
simple to, or a valid leasehold interest in, all its material real
property, and good title to, or a valid leasehold interest in, all its
other material property, and none of such property is subject to any Lien,
except for Permitted Liens.

     6.9 Intellectual Property.

     Each Consolidated Party owns, or has the legal right to use, all
trademarks, tradenames, copyrights, technology, know-how and processes, if
any, necessary for each of them to conduct its business as currently
conducted (the "Intellectual Property") except for those the failure to own
or have such legal right to use would not be reasonably expected to have a
Material Adverse Effect. No claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property
or the validity or effectiveness of any such Intellectual Property, nor
does Airgas know of any such claim, and the use of such Intellectual
Property by any Consolidated Party does not infringe on the rights of any
Person, except for such claims and infringements that in the aggregate,
would not be reasonably expected to have a Material Adverse Effect.

     6.10 No Burdensome Restrictions.

     Except as previously disclosed in writing to the Lenders on or prior
to the Closing Date, no Requirement of Law or contractual obligation of any
Consolidated Party would be reasonably expected to have a Material Adverse
Effect.





     6.11 Taxes.

     Each Consolidated Party has filed or caused to be filed all income tax
returns and all other material tax returns which, to the best knowledge of
Airgas, are required to be filed and has paid (a) all taxes shown to be due
and payable on said returns or (b) all taxes shown to be due and payable on
any assessments of which it has received notice made against it or any of
its property and all other taxes, fees or other charges imposed on it or
any of its property by any Governmental Authority (other than any (i)
taxes, fees or other charges with respect to which the failure to pay, in
the aggregate, would not have a Material Adverse Effect or (ii) taxes, fees
or other charges the amount or validity of which are currently being
contested and with respect to which reserves in conformity with GAAP have
been provided on the books of such Person), and no tax Lien has been filed,
and, to the best knowledge of Airgas, no claim is being asserted, with
respect to any such tax, fee or other charge.

     6.12 ERISA.

     Except as would not result in a Material Adverse Effect:

     (a) During the five-year period prior to the date on which this
representation is made or deemed made: (i) no Termination Event has
occurred, and, to the best knowledge of Airgas, no event or condition has
occurred or exists as a result of which any Termination Event could
reasonably be expected to occur, with respect to any Plan; (ii) no
"accumulated funding deficiency," as such term is defined in Section 302 of
ERISA and Section 412 of the Code, whether or not waived, has occurred with
respect to any Plan; (iii) each Single Employer Plan and, to the best
knowledge of Airgas, each Multiemployer Plan has been maintained, operated,
and funded in compliance with its own terms and in material compliance with
the provisions of ERISA, the Code, and any other applicable federal or
state laws; and (iv) no lien in favor of the PBGC or a Plan has arisen or
is reasonably likely to arise on account of any Plan.

     (b) The actuarial present value of all "benefit liabilities" under all
Single Employer Plans (determined within the meaning of Section 401(a)(2)
of the Code, utilizing the actuarial assumptions used to fund such Plans),
whether or not vested, did not, as of the last annual valuation date prior
to the date on which this representation is made or deemed made, exceed the
current value of the assets of all such Plans.

     (c) No Consolidated Party or any ERISA Affiliate has incurred, or, to
the best knowledge of Airgas, could be reasonably expected to incur, any
withdrawal liability under ERISA to any Multiemployer Plan or Multiple
Employer Plan. No Consolidated Party or any ERISA Affiliate would become
subject to any withdrawal liability under ERISA if any Consolidated Party
or any ERISA Affiliate were to withdraw completely from all Multiemployer
Plans and Multiple Employer Plans as of the valuation date most closely
preceding the date on which this representation is made or deemed made. 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 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 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. In addition, no
Consolidated Party is (i) an "investment company" registered or required to
be registered under the Investment Company Act of 1940, as amended, and is
not controlled by such a company, or (ii) a "holding company", or a
"subsidiary company" of a "holding company", or an "affiliate" of a
"holding company" or of a "subsidiary" of a "holding company", within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

     (c) No director, executive officer or principal shareholder of any
Consolidated Party is a director, executive officer or principal
shareholder of any Lender. For the purposes hereof the terms "director",
"executive officer" and "principal shareholder" (when used with reference
to any Lender) have the respective meanings assigned thereto in Regulation
O issued by the Board of Governors of the Federal Reserve System.

     condition exist, the effect of which default or other event or
     condition is to cause, or permit, the holder or holders of such
     Indebtedness (or trustee or agent on behalf of such holders) to cause

     required), any such Indebtedness to become due prior to its stated
     maturity; or (B) any such Indebtedness shall be declared due and
     payable, or required to be prepaid other than by a regularly scheduled

     or bonded pending appeal within 30 days from the entry thereof; or

          acquisition, the 30 day period referenced above in the foregoing
          proviso shall commence on the date of the filing with the
          Securities and Exchange Commission of such tender offer
          statement.

          Canadian Borrower pursuant to Section 3.5.

     continuing any "Event of Default" (or any comparable term) under, and
     as defined in, any Junior Financing Documentation, (ii) any of the

     9.2 Acceleration; Remedies.





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

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

          (ii) Acceleration. Declare the unpaid principal of and any
     accrued interest in respect of all Loans, any reimbursement
     obligations arising from drawings under Letters of Credit and any and
     all other indebtedness or obligations of any and every kind owing by
     any Credit Party to an Agent and/or any of the Lenders hereunder to be
     due whereupon the same shall be immediately due and payable without
     presentment, demand, protest or other notice of any kind, all of which
     are hereby waived by the Credit Parties.

          (iii) Cash Collateral. Direct the Credit Parties to pay (and each
     Credit Party agrees that upon receipt of such notice, or upon the
     occurrence of an Event of Default under Section 9.1(f), it will
     immediately pay) to the U.S. Agent (A) additional cash, to be held by
     the U.S. Agent, for the benefit of the U.S. Lenders, in a cash
     collateral account as additional security for the U.S. LOC Obligations
     in respect of subsequent drawings under all then outstanding U.S.
     Letters of Credit in an amount equal to the maximum aggregate amount
     which may be drawn under all U.S. Letters of Credits then outstanding

                             AGENCY PROVISIONS

     10.1 Appointment.

     Each Lender hereby designates and appoints Bank of America as the U.S.

shall not have any duties or responsibilities, except those expressly set
forth herein and therein, or any fiduciary relationship with any Lender,
and no implied covenants, functions, responsibilities, duties, obligations
or liabilities shall be read into this Credit Agreement or





any of the other Credit Documents, or shall otherwise exist against the
Agents. 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. Neither of the Agents shall be responsible for the negligence
or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

     10.3 Exculpatory Provisions.

     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 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 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 and (B)
the Revolving Canadian Commitments 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. 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 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. If no
successor administrative agent has accepted appointment as U.S. Agent or
Canadian Agent, as applicable, by the date which is 30 days following a
retiring Agent's notice of resignation, the retiring Agent's resignation
shall nevertheless thereupon become effective and the Lenders shall perform
all of the duties of such retiring Agent hereunder until such time, if any,
as the Required Lenders appoint a successor agent as provided for above.
Upon the resignation or removal of the U.S. Agent, Bank of America shall be
entitled to resign as U.S. Issuing Lender and U.S. Swingline Lender. Upon
the resignation or removal of the Canadian Agent, CIBC shall be entitled to
resign as Canadian Issuing Lender and Canadian Swingline Lender.

     10.10 Collateral Agent.





     Each Lender hereby designates and appoints Bank of America as the
Collateral Agent to act as specified herein and the other Credit Documents
following the occurrence of each Partial Collateralization Date or Full
Collateralization Date, if any, and until the occurrence of any
corresponding Collateral Release Date, and each such Lender hereby
authorizes the Collateral Agent as the agent for such Lender, to take such
action on its behalf under the provisions of this Credit Agreement and the
other Credit Documents and to exercise such powers and perform such duties
as are expressly delegated by the terms hereof and of the other Credit
Documents, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere herein and
in the other Credit Documents, the Collateral Agent shall not have any
duties or responsibilities, except those expressly set forth herein and
therein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities
shall be read into this Credit Agreement or any of the other Credit
Documents, or shall otherwise exist against the Collateral Agent. The
Lenders and the Agents agree that the Collateral Agent shall be entitled to
all of the benefits and privileges of this Section 10 to the same extent as
the U.S. Agent.

     11.2 Right of Set-Off.

     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, 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 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 Borrower 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 (so long as no Default or Event of
Default exists) 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 (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 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 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. 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; (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; and (viii) such assignee
agrees that it will be bound by the terms of the Intercreditor Agreement,
regardless of whether such assignee becomes a signatory thereto.

     (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 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 Borrowers 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 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:

     obligations arising from drawings under Letters of Credit, or 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

     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;

     dissolution, merger, amalgamation or disposition of a Consolidated
     Party not prohibited by Section 8.4 or as otherwise permitted by any
     Credit Document, release the Borrowers or substantially all of the
     other Credit Parties from its or their obligations under the Credit
     Documents; or

          (viii) to the extent the Credit Party Obligations have become

Agents.

each of which when so executed and delivered shall be an original, but all

     11.10 Governing Law; Submission to Jurisdiction; Venue.

     (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE
RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE
GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK. Any legal action or proceeding with respect to this
Credit Agreement or any other Credit Document may be brought in the courts
of the State of New York in New York County, or of the United States for
the Southern District of New York, and, by execution and delivery of this
Credit Agreement, each Credit Party hereby irrevocably accepts for itself
and in respect of its property, generally and unconditionally, the
nonexclusive jurisdiction of such courts. Each Credit Party further
irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to it at
the address set out for notices pursuant to Section 11.1, such service to
become effective three (3) days after such mailing. Nothing herein shall
affect the right of the U.S. Agent to serve process in any other manner
permitted by law or to commence legal proceedings or to otherwise proceed
against a Credit Party in any other jurisdiction.

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

     (c) With respect to the guaranty obligations of the Canadian
Guarantors arising under Section 12:

          (i) (A) Without limiting the generality of subsections (a) and
     (b) of this Section 11.10, each Canadian Guarantor 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 Lenders, be settled immediately
     by submitting the same to binding arbitration in the City of New York,
     New York (or such other place as the parties may agree) in accordance
     with the Commercial Arbitration Rules then obtaining of the American
     Arbitration Association. Upon the request and submission of any
     controversy or claim for arbitration hereunder, the Canadian Agent
     shall give the Canadian Guarantors not less than 45 days written
     notice of the request for arbitration, the nature of the controversy
     or claim, and the time and place set for arbitration. Each Canadian
     Guarantor 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 New York or any Federal court
     sitting in the State of New York. The expenses of arbitration shall be
     paid by the Canadian Guarantors.

          (B) The provisions of subparagraph (A) above are intended to
     comply with the requirements of the Convention on the Recognition and
     Enforcement of Foreign Arbitral Awards (the "Convention"). To the
     extent that any provisions of such subparagraph (A) are not consistent





     with or fail to conform to the requirements set out in the Convention,
     such subparagraph (A) shall be deemed amended to conform to the
     requirements of the Convention.

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

          (ii) The guarantee of the Canadian Guarantors under Section 12 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 the Canadian Guarantors under Section 12. The
     payment obligation of the Canadian Guarantors 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 the Canadian Guarantors, 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 the Canadian Guarantors for the additional amount necessary to
     yield the amount due and owing to the Canadian Agent and the Canadian
     Lenders.

     (d) TO THE EXTENT PERMITTED BY LAW, EACH OF THE AGENT, THE LENDERS AND
THE CREDIT PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN
ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS
CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

     11.11 Severability.

     If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable
and the remaining provisions shall remain in full force and effect and
shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

     11.12 Entirety.

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

     11.13 Binding Effect; Termination.

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

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





     11.14 Confidentiality.

     The Agents and the Lenders agree to keep confidential (and to cause
their respective Affiliates, officers, directors, employees, agents and
representatives to keep confidential) all information, materials and
documents furnished to the Agents or any such Lender by or on behalf the
Credit Parties (whether before or after the Closing Date) which relates to
the Consolidated Parties (the "Information"). Notwithstanding the
foregoing, the Agents and each Lender shall be permitted to disclose
Information (i) to its Subsidiaries, its Affiliates under direct or
indirect common control with it, its officers, its directors, its
employees, its agents and its representatives who need to know such
Information in connection with its participation in any of the transactions
evidenced by this Credit Agreement or any other Credit Documents or the
administration of this Credit Agreement or any other Credit Documents; (ii)
to the extent required by applicable laws and regulations or by any
subpoena or similar legal process, or requested by any Governmental
Authority; (iii) to the extent such Information (A) becomes publicly
available other than as a result of a breach of this Credit Agreement or
any agreement entered into pursuant to clause (iv) below, (B) becomes
available to such Agent or such Lender on a non-confidential basis from a
source other than the Credit Parties or (C) was available to the Agents or
such Lender on a non-confidential basis prior to its disclosure to such
Agent or such Lender by the Credit Parties; (iv) to any assignee or
participant (or prospective assignee or participant) so long as such
assignee or participant (or prospective assignee or participant) first
specifically agrees in a writing reasonable to Airgas furnished to and for
the benefit of the Credit Parties to be bound by the terms of this Section
11.14; or (v) to the extent that the Credit Parties shall have consented in
writing to such disclosure. Nothing set forth in this Section 11.14 shall
obligate the Agents or any Lender to return any materials furnished by the
Credit Party.

     11.15 Conflict.

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


                                 SECTION 12

                                  GUARANTY

     12.1 The Guaranty.

     (a) U.S. Guarantors. Each of the U.S. Guarantors hereby jointly and
severally guarantees to each Lender, each Affiliate of a Lender that enters
into a Hedging Agreement with a Borrower and the Agents as hereinafter
provided, as primary obligor and not as surety, the prompt payment of the
Credit Party 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 U.S. Guarantors hereby further agree that if any of the Credit
Party 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 U.S. Guarantors will, jointly and
severally, 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 Credit Party 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.

     (b) Canadian Guarantors. Each of the Canadian Guarantors hereby
jointly and severally guarantees to each Canadian Lender, each Affiliate of
a Canadian Lender that enters into a Hedging Agreement with a Canadian
Borrower and the Agents as hereinafter provided, as primary obligor and not
as surety, the prompt payment of the Canadian 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 Canadian Guarantors hereby further agree that
if any of the Canadian 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 Canadian Guarantors
will, jointly and severally, 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 Obligations, the same will be promptly
paid in full when





due (whether at extended maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) in
accordance with the terms of such extension or renewal.

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

     12.2 Obligations Unconditional.

     The obligations of the U.S. Guarantors under Section 12.1 with respect
to the Credit Party Obligations and the obligations of the Canadian
Guarantors under Section 12.1 with respect to the Canadian Obligations are,
in each case, joint and several, absolute and unconditional, irrespective
of the value, genuineness, validity, regularity or enforceability of any of
the Credit Documents, or Hedging Agreements between any Lender or Affiliate
of a Lender and the applicable Borrower, 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 Credit Party
Obligations or the Canadian Obligations, as the case may be, and, to the
fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or
equitable discharge or defense of a surety or guarantor, it being the
intent of this Section 12.2 that the respective obligations of the U.S.
Guarantors and the Canadian Guarantors hereunder shall be absolute and
unconditional under any and all circumstances. Each Guarantor agrees that
such Guarantor shall have no right of subrogation, indemnity, reimbursement
or contribution against the applicable Borrower or any other applicable
Guarantor of the Canadian Obligations for amounts paid under this
Section 12 until such time as the Lenders (and any Affiliates of Lenders
entering into Hedging Agreements with the applicable Borrower) have been
paid in full in respect of all Credit Party Obligations or all Canadian
Obligations, as the case may be, 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
or Hedging Agreements between the applicable Borrower and any Lender, or
any Affiliate of a Lender. 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 any Guarantor hereunder which shall remain absolute and
unconditional as described above:

          (a) at any time or from time to time, without notice to any
     Guarantor, the time for any performance of or compliance with any of
     the Credit Party Obligations or Canadian Obligations, as the case may
     be, shall be extended, or such performance or compliance shall be
     waived;

          (b) any of the acts mentioned in any of the provisions of any of
     the Credit Documents, any Hedging Agreement between the applicable
     Borrower and any Lender, or any Affiliate of a Lender, or any other
     agreement or instrument referred to in the Credit Documents or such
     Hedging Agreements shall be done or omitted;

          (c) the maturity of any of the Credit Party Obligations or
     Canadian Obligations, as the case may be, shall be accelerated, or any
     of the Credit Party Obligations or Canadian Obligations, as the case
     may be, shall be modified, supplemented or amended in any respect, or
     any right under any of the Credit Documents, any Hedging Agreement
     between the applicable Borrower and any Lender, or any Affiliate of a
     Lender, or any other agreement or instrument referred to in the Credit
     Documents or such Hedging Agreements shall be waived or any other
     guarantee of any of the Credit Party Obligations or Canadian
     Obligations, as the case may be, or any applicable security therefor
     shall be released, impaired or exchanged in whole or in part or
     otherwise dealt with;

          (d) any Lien granted to, or in favor of, the U.S. Agent or any
     Lender or Lenders as security for any of the Credit Party Obligations
     or the Canadian Obligations, as the case may be, shall fail to attach
     or be perfected; or

          (e) any of the Credit Party Obligations or Canadian Obligations,
     as the case may be, shall be determined to be void or voidable
     (including, without limitation, for the benefit of any creditor of any





     applicable Guarantor) or shall be subordinated to the claims of any
     Person (including, without limitation, any creditor of applicable
     Guarantor).

     With respect to its obligations hereunder, each Guarantor hereby
expressly waives diligence, presentment, demand of payment, protest and all
notices whatsoever, and any requirement that the Agents or any Lender
exhaust any right, power or remedy or proceed against any Person under any
of the Credit Documents, any Hedging Agreement between the applicable
Borrower and any Lender, or any Affiliate of a Lender, or any other
agreement or instrument referred to in the Credit Documents or such Hedging
Agreements, or against any other Person under any other guarantee of, or
security for, any of the Credit Party Obligations or Canadian Obligations,
as the case may be. The rights of the Agents and the Lenders and the
Affiliates of any of the Lenders contained herein shall be in addition to
and independent of all other rights which they may at any time have or hold
in respect of any of the Credit Party Obligations or Canadian Obligations.

     12.3 Reinstatement.

     The obligations of the Guarantors under this Section 12 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 Credit Party
Obligations or the Canadian Obligations, as the case may be, is rescinded
or must be otherwise restored by any holder of any of the Credit Party
Obligations or the Canadian Obligations, as the case may be, whether as a
result of any proceedings in bankruptcy or reorganization or otherwise, and
each Guarantor agrees that it will indemnify the Agents and each Lender on
demand for all reasonable costs and expenses (including, without
limitation, fees and expenses of counsel) incurred by such Agent or such
Lender in connection with such rescission or restoration, including any
such costs and expenses incurred in defending against any claim alleging
that such payment constituted a preference, fraudulent transfer or similar
payment under any bankruptcy, insolvency or similar law.

     12.4 Certain Additional Waivers.

     Without limiting the generality of the provisions of this Section 12,
each Guarantor hereby specifically waives the benefits of N.C. Gen. Stat.
Sections 26-7 through 26-9, inclusive, to the extent applicable. Each Guarantor
further agrees that it shall have no right of recourse to security for the
Credit Party Obligations or the Canadian Obligations, as the case may be,
except through the exercise of the rights of subrogation pursuant to
Section 12.2.

     12.5 Remedies.

     The Guarantors agrees that, to the fullest extent permitted by law, as
between the applicable Guarantors, on the one hand, and the Agents and the
Lenders, on the other hand, the Credit Party Obligations or the Canadian
Obligations, as the case may be, may be declared to be forthwith due and
payable as provided in Section 9.2 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said
Section 9.2) for purposes of Section 12.1 notwithstanding any stay,
injunction or other prohibition preventing such declaration (or preventing
the Credit Party Obligations from becoming automatically due and payable)
as against any other Person and that, in the event of such declaration (or
the Credit Party Obligations being deemed to have become automatically due
and payable), the Credit Party Obligations and/or the Canadian Obligations,
as the case may be, (whether or not due and payable by any other Person)
shall forthwith become due and payable by the applicable Guarantors for
purposes of Section 12.1. The Guarantors acknowledge and agree that to the
extent their obligations hereunder become secured in accordance with the
terms of the Collateral Documents, the Lenders may exercise their remedies
thereunder in accordance with the terms thereof.

     12.6 Guarantee of Payment; Continuing Guarantee.

     The guarantee in this Section 12 is a guaranty of payment and not of
collection, is a continuing guarantee, and shall apply to all Credit Party
Obligations whenever arising.
