                                  (Unaudited)
(1)   BASIS OF PRESENTATION
      _____________________

      The consolidated financial statements include the accounts of Airgas,
Inc. and its subsidiaries (the "Company").  Unconsolidated affiliates are
accounted for on the equity method and generally consist of 20 - 50% owned
operations where control does not exist or is considered temporary.  The
excess of the cost of these affiliates is being amortized over 40 years. 
Intercompany accounts and transactions are eliminated in consolidation.

      The accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles applicable to interim
financial statements.  These statements do not include all disclosures
required for annual financial statements.  These financial statements should
be read in conjunction with the more complete disclosures contained in the
Company's audited consolidated financial statements for the year ended March
31, 1997.

      The financial statements reflect, in the opinion of management, all
adjustments (normal recurring adjustments) necessary to present fairly the 
Company's consolidated balance sheets at December 31, 1997 and March 31, 1997;
the consolidated statements of earnings for the three and nine months ended
December 31, 1997 and 1996; and the consolidated statements of cash flows for
the nine months ended December 31, 1997 and 1996. The interim operating
results are not necessarily indicative of the results to be expected for an
entire year.

      Certain reclassifications have been made to previously issued financial
statements to conform to the current presentation.  Four businesses with
annual sales of approximately $40 million which were previously reported with
the Distribution segment are now reported with the Manufacturing segment.

(2)   ACQUISITIONS
      ____________

      From April 1, 1997 to December 31, 1997, the Company acquired seventeen
industrial gas distributors with aggregate annual sales of approximately $60
million, including two large regional distributors, Industrial Gas Products
("IGP") and JWS Technologies, Inc.  The Company has also acquired two
industrial products distributors with combined annual sales of approximately
$106 million and four carbon dioxide distributors with combined annual sales
of approximately $74 million.  The aggregate purchase price, which includes
amounts related to non-competition and confidentiality agreements, amounted to
approximately $249 million and includes real estate acquired of approximately
$14 million.  Included in the aggregate purchase price is the issuance of
approximately 1.8 million treasury shares which were reissued in connection
with the acquisition of Carbonic Industries Corporation ("CIC").  In addition,
the Company issued approximately 1.2 million shares in connection with the
acquisition of IGP.  Acquisitions have been recorded using the purchase method
of accounting, and, accordingly, results of their operations have been
included in the Company's consolidated financial statements since the
effective dates of the respective acquisitions.

      Subsequent to December 31, 1997, the Company acquired four industrial
gas distributors with annual sales of approximately $17 million, and one
carbon dioxide distributor with annual sales of approximately $5 million.

(3)   NON-RECURRING GAINS
      ___________________

      On December 23, 1996, the Company announced it was the victim of a
fraudulent breach of contract by a third-party supplier of refrigerant gas. 
In connection with the fraud, the Company recorded a non-recurring pre-tax
charge during the fourth quarter of fiscal 1997 of $26.4 million
(approximately $17 million after-tax) for product losses and costs associated
with the Company's investigation into the fraud.  The Distribution subsidiary
which reported the special charge in fiscal 1997 is reported with the
Manufacturing segment in fiscal 1998.  On July 28, 1997, the Company reported
that it had negotiated a comprehensive settlement with all the defendants in
litigation brought by the Company to recover such losses.  As a result of the
recovery, the Company recorded a non-recurring pre-tax gain during the second
quarter of $14.5 million (approximately $9.4 million after- tax).  Aggregate
recoveries to date of $20.1 million represent cash received, offset by
additional costs and expenses incurred year-to-date, estimated future out-of-
pocket costs and other reserves which total $5.6 million.  The Company
continues to pursue additional recoveries including proceeds from insurance
policies.  

      The Company also recorded a pre-tax gain, included in other income, in
the second quarter of approximately $1.5 million (approximately $980 after-
tax) related to the sale of a non-core business.

(4)   EARNINGS PER SHARE
      __________________

      Basic earnings per share amounts were determined using the weighted
average number of shares outstanding.  Diluted earnings per share amounts were
determined using the treasury stock method.  

      In February 1997, the Financial Accounting Standards Board issued SFAS
No. 128, "Earnings per Share" ("SFAS No. 128").  SFAS No. 128 establishes new
standards for computing and presenting earnings per share ("EPS") and requires
the disclosure of Basic and Diluted EPS, effective for financial statements
issued for periods ending after December 15, 1997, including interim periods. 

      Effective with its third quarter ended December 31, 1997, the Company
implemented SFAS No. 128.  For the Company, Diluted EPS is the same as
previously reported EPS amounts.  All prior periods have been restated to
conform to the new rules.  The difference between the Basic and Diluted common
equivalent shares outstanding is a result of common share equivalents related
to stock options.

tortious interference with business or contractual relations with respect to
Praxair's Right of First Refusal contract with National Welders by the Company
in connection with the Company's formation of a joint venture with the
majority shareholders of National Welders.  Praxair is seeking compensatory
damages in excess of $100 million and punitive damages.  The Company believes
that Praxair's claims are without merit and intends to defend vigorously
against such claims.

     On September 9, 1996, the Company filed suit against Praxair in the Court
of Common Pleas of Philadelphia County, Pennsylvania.  The complaint alleges
breach of contract, fraud, conversion and misappropriation of trade secrets
with respect to an agreement between Praxair and the Company, pursuant to
which Praxair induced the Company to provide Praxair valuable information and
conclusions developed by the Company concerning CBI Industries, Inc. ("CBI")
in exchange for Praxair's promise not to acquire CBI without the Company's
participation.  The Company has alleged that it became entitled, pursuant to 
such agreement, to acquire certain of CBI's assets having a value in excess of
$800 million.  The Company is seeking compensatory and punitive damages.  

     The Company is involved in other various legal proceedings which have
arisen in the ordinary course of its business and have not been finally
adjudicated.  These actions, when ultimately concluded and determined, will
not, in the opinion of management, have a material adverse effect upon the
Company's financial condition, results of operations or liquidity.

FINANCIAL REVIEW
________________
OVERVIEW
________

      The Company's financial results for the third quarter ended December 31,
1997 reflect continued growth compared with the third quarter last year.   Net
sales increased 24% to $367.8 million from $297.2 million in the third quarter
last year. After-tax cash flow (net earnings plus depreciation, depletion,
amortization and deferred taxes) increased by 15% to a record $34.4 million,
compared to $29.7 million for the same quarter last year.  Net earnings were
$11.8 million, or $.17 per share, compared to $11.0 million, or $.16 per share
a year ago.  

      Growth in the industrial gas distribution business continued with the
acquisition of seventeen industrial gas distributors from April 1, 1997 to
December 31, 1997, with annual sales of approximately $60 million, including
two large regional distributors, Industrial Gas Products and JWS Technologies,
Inc.  Internal growth and expansion of existing product lines resulted in
same-store sales growth of 3% and same-store gross profit growth of 3.6%
compared to the same period in the prior year.   
   
      Since April 1, 1997, Airgas Direct Industrial ("ADI") has acquired two
strategic industrial products distributors:  (1) Kendeco Industrial Supply, an
"engineered-systems integrator" for the cutting tools and abrasives market
with annual sales of approximately $16 million, and (2) Lyons Safety, Inc., a
national marketer of safety and personal protection systems with annual sales
of approximately $90 million.   These two acquisitions strengthen ADI's
position through the expansion of product lines (safety products and
metalworking tools) in the largest geographical market for industrial
supplies, and through additional marketing and service capabilities to larger
customers.  In addition, ADI realized same-store sales growth of 16%, and
same-store gross profit growth of approximately 19%, compared to the same
period in the prior year.   

      The Manufacturing segment's expansion into carbon dioxide continued,
with the acquisition of four carbon dioxide distributors since April 1, 1997,
with aggregate annual sales of approximately $74 million.  With these
acquisitions, the Company's combined annual sales of carbon dioxide and dry
ice products total in excess of $100 million.  These acquisitions, combined
with other businesses acquired in fiscal 1997, enhance the Company's ability
to supply carbon dioxide and dry ice products through its distribution
network.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
         OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

      The fraudulent breach of contract by a third-party supplier of
refrigerant gas was reported by the Company on December 23, 1996.  In
connection with the fraud, the Company recorded a non-recurring pre-tax charge
during the fourth quarter of fiscal 1997 of $26.4 million (approximately $17
million after-tax) for product losses and costs associated with the Company's
investigation into the fraud.  On July 28, 1997, the Company reported that it
had negotiated a comprehensive settlement with all defendants in the
litigation described above.  As a result of the recovery, the Company recorded
a non-recurring gain in the second quarter of $14.5 million  (approximately
$9.4 million after-tax).  The Company continues to pursue additional
recoveries including proceeds from insurance policies.

      For the quarter ended December 31, 1997, Distribution sales increased
approximately $13 million from the acquisition of 30 distributors since
October 1, 1996 and approximately $8 million from same-store sales.  The
increase in same-store Distribution sales of 3% was more heavily weighted
towards lower margin hardgoods with internal growth primarily attributable to
higher sales volumes.  The prior period included the benefit of approximately
$3 million in non-recurring large sales of refrigerants and sulfur
hexafluoride.  Excluding these sales, the Company realized same-store sales
growth of approximately 4.3%.  The Company continues to focus on internal
sales growth through the development of new gas products and product-line
extensions, including specialty gases, small bulk gases, carbon dioxide,
replacement refrigerants in returnable containers, expansion of rental welder
fleets and increased hardgoods business through ADI product lines. 

      The Company believes its same-store sales growth is slightly understated
since it does not reflect the Company's decision to cease unprofitable sales
to certain customers and other sales lost during acquisition consolidation and
integration activity.  The Company estimates same-store sales based on a
comparison of current period sales to the prior period's sales, adjusted for
acquisitions. Future same-store sales growth is dependent on the economy and
the Company's ability to expand markets for new and existing products and to
increase prices.

     ADI's sales include welding, metalworking, safety and other Maintenance,
Repair and Operations ("MRO") hardgoods.  The internal sales growth rate for
ADI was approximately 16% during the third quarter of fiscal 1998.  In
addition, ADI has completed two acquisitions in fiscal 1998 to expand product
lines, geographic coverage and enhance marketing and service capabilities. 
Sales to the Distribution segment totaled approximately $700 thousand for the
quarter ended December 31, 1997 compared to approximately $244 thousand in the
same quarter in the prior year, and are eliminated in consolidation.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
         OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

     The Manufacturing segment's sales increased $17.4 million during the
third quarter primarily as a result of recent acquisitions.  Strong sales of
calcium carbide and nitrous oxide were offset slightly by lower shipments of
certain carbon products.  Four businesses with annual sales of approximately
$40 million which were previously reported with the Distribution segment are
now reported with the Manufacturing segment.  Sales to the Distribution
segment totaled approximately $3 million for the quarter ended December 31,
1997 compared to approximately $2.3 million in the same quarter in the prior
year, and are eliminated in consolidation.

      The increase in Distribution gross profits of approximately $11.4
million over the same quarter in the prior year resulted from acquisitions
which contributed approximately $6.6 million and from same-store gross profit
growth of 3.6% or approximately $4.8 million.  Same-store gross profit growth
resulted primarily from sales volume growth.  On a same-store basis, the
Distribution gross margin increased 30 basis points compared to the same
period in the prior year primarily as a result of  higher gas margins. 
Hardgoods and rent margins also improved slightly compared to the prior
period.  Hardgoods accounted for 51.1% of total sales compared to 49.9% in the
same period last year.  Finally, bulk tank rent related to small bulk
installations, and an increased base of rental welding equipment and the
return of third-party rented cylinders continued to help same-store gross
profit growth. 

     For the quarter, ADI's gross margin of 28.6% was down 210 basis points
compared to the same quarter last year as a result of fiscal 1998
acquisitions.  Same-store gross profit growth of approximately $2.7 million
resulted primarily from sales volume growth.       

     For the quarter, the Manufacturing gross margin of 52.7% compared
favorably to the same quarter last year as a result of acquisitions completed
since October 1, 1997.

     Selling, distribution, and administrative expenses ("SG&A") increased
$23.9 million compared to the same quarter last year primarily due to
acquisitions.  SG&A expenses as a percentage of sales increased 30 basis
points to 32.3% compared to the same period in the prior quarter.  As a
percentage of sales, increases in operating expenses were offset by ADI
acquisitions which have a lower expense-to-sales ratio than the Distribution
and Manufacturing segments.  The Company anticipates additional operating
costs resulting from the consolidation of operating companies and from the
integration and standardization of information systems during fiscal years
1998, 1999 and 2000.  

     Depreciation, depletion and amortization increased $3.7 million compared
to the same period in the prior quarter due to acquisitions and from increased
capital expenditures.

     The Distribution segment's operating margin decreased 30 basis points to
9.9% compared with the same period in the prior year.  The decrease resulted
primarily from slightly higher operating costs and expenses, recent new hub
acquisitions which have lower operating margins and lower same-store gross
profit growth.  Subject to the effects of future acquisitions and the
Company's ability to increase sales and expand gross margins, the Company
continues to focus on improving its operating margin by implementing selective
price increases, reducing costs by leveraging its national purchasing power
and continuing to integrate acquisitions.

     The operating income margin for ADI increased 70 basis points to 4%
compared with the same quarter last year.  The increase resulted partially
from higher same-store gross profits.  The Company believes that ADI's
operating income margin will continue to be impacted by expansion costs
related to information systems, infrastructure and facility enhancements.  ADI
is establishing new distribution centers in Southern California and near
Atlanta, Georgia, which will consolidate other ADI warehouses.  Non-recurring
moving costs associated with the new distribution centers will impact ADI's
performance during the fourth quarter by approximately one-half penny per
share.  The Company expects the distribution center in California to be
operational by March 31, 1998 and the distribution center in Georgia to be
operational by the summer of 1998.    

     The Manufacturing segment's operating income increased $616 thousand
compared to the same quarter last year primarily as a result of acquisitions. 
Operating margin decreased to 10% compared to 17% in the same period in the
prior year as a result of recent acquisitions which have a lower operating
income margin.
 
      Interest expense, net, increased $3.1 million compared to the same
quarter last year primarily as a result of the increase in average outstanding
debt associated with the acquisition of businesses acquired since October 1,
1996, interest costs on debt associated with the refrigerant fraud and the
repurchase of the Company's common stock.

     Income tax expense represented 42.1% of pre-tax earnings in 1998 and
1997.

      For the nine months ended December 31, 1997, Distribution sales
increased approximately $39 million resulting from the acquisition of 37
distributors since April 1, 1996 and approximately $32 million from same-store
sales growth.  The increase in same-store Distribution sales of approximately
4% was a result of sales volume growth in all three product groups: gases,
hardgoods and rent.  The Company continues to focus on internal sales growth
through the development of new gas products and product-line extensions,
including specialty gases, small bulk gases, carbon dioxide, replacement
refrigerants in returnable containers, expansion of rental welder fleets and
increased hardgoods business through ADI product lines. The Company believes
its same-store sales growth is slightly understated since it does not reflect
the Company's decision to cease unprofitable sales to certain customers and
other sales lost during acquisition consolidation and integration activity. 
The Company estimates same-store sales based on a comparison of current period
sales to the prior period's sales, adjusted for acquisitions. Future
same-store sales growth is dependent on the economy and the Company's ability
to expand markets for new and existing products and to increase prices.

     ADI's sales include welding, metalworking, safety and other MRO
hardgoods.  The internal sales growth rate for ADI was approximately 15% for
the nine months ended December 31, 1997.  Sales to the Distribution segment
totaled approximately $1.6 million for the nine months ended December 31, 1997
compared to approximately $322 thousand in the prior year, and are eliminated
in consolidation.

     The Manufacturing segment's sales increased approximately $45 million
during the nine months ended December 31, 1997, primarily as a result of
acquisitions.  Strong sales of calcium carbide and nitrous oxide were offset
slightly by lower sales of certain carbon products.  Four businesses with
annual sales of approximately $40 million which were previously reported with
the Distribution segment are now reported with the Manufacturing segment. 
Sales to the Distribution segment totaled approximately $6.7 million for the
nine months ended December 31, 1997 compared to approximately $5.2 million in
the prior year, and are eliminated in consolidation.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
         OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)


      The increase in Distribution gross profits of approximately $35 million
compared to the prior period resulted from acquisitions which contributed
approximately $17 million and from same-store gross profit growth of 4.6% or
approximately $18 million.  Same-store gross profit growth resulted primarily
from sales volume growth with same-store margins increasing slightly.  On a
same-store basis, the Distribution gross margin increased 20 basis points
compared to the same period in the prior year, primarily as a result of higher
gas margins.  Hardgoods margins also improved slightly compared to the prior
period.  Hardgoods accounted for 51.6% of total sales compared to 50.7% in the
prior period.  The improvement in gas margins is attributable to non-recurring
lower margin refrigerant and sulfur hexafluoride sales in the prior period and
from selective price increases.  

     For the nine months ended December 31, 1997, ADI's gross margin of 28%
compared favorably to the prior year as a result of the September 1, 1996
acquisition of Rutland, which has a historical gross margin of approximately
40%.  Same-store gross profit growth of approximately $6 million resulted
primarily from sales volume growth.

     For the nine months ended December 31, 1997, the Manufacturing gross
margin of 52.7% compared favorably to the prior period as a result of
acquisitions.  

     Selling, distribution, and administrative expenses ("SG&A") increased
$67.8 million compared to the same period last year primarily due to
acquisitions.  SG&A expenses as a percentage of sales of 31.9% were
essentially flat compared to the same period in the prior year.  Subject to
future acquisitions, the Company believes that as it continues to integrate
acquisitions and complete start-up and expansion activities, SG&A expenses
relative to net sales should improve. The Company anticipates additional
operating costs resulting from the consolidation of operating companies and
from the integration and standardization of information systems during fiscal
years 1998, 1999 and 2000.  

     Depreciation, depletion and amortization increased $11 million compared
to the same period in the prior year due to acquisitions and from increased
capital expenditures.

      Excluding a non-recurring gain of $14.5 million, operating income
increased 15.7% in 1997 compared to 1996:

                               ======            ======            ======

     The Distribution segment's operating margin was essentially flat at 10.2%
compared with last year.  Subject to the effects of future acquisitions and
the Company's ability to increase sales and expand margins, the Company
continues to focus on improving its operating margin by implementing selective
price increases, reducing costs by leveraging its national purchasing power
and continuing to integrate acquisitions.

     For the nine months ended December 31, 1997, the operating income margin
for ADI decreased 20 basis points to 3.1% compared with last year.  The
Company believes that ADI's operating income margin will continue to be
impacted by expansion costs related to information systems, infrastructure and
facility enhancements.  ADI is establishing new distribution centers in
Southern California and near Atlanta, Georgia which will consolidate other ADI
warehouses.  Non-recurring moving costs associated with the new distribution
centers will impact ADI's performance during the fourth quarter by
approximately one-half penny per share.  The Company expects the distribution
center in California to be operational by March 31, 1998 and the distribution
center in Georgia to be operational by the summer of 1998.

     The Manufacturing segment's operating income increased $4.4 million
compared to last year primarily as a result of acquisitions.  Operating margin
decreased to 13% compared to 17% in the prior year as a result of recent
acquisitions which have a lower operating income margin.

      During the second quarter ended of fiscal 1998, the Company recorded a
non-recurring pre-tax gain of approximately $14.5 million (approximately $9.4
million after-tax).  See Note 3 to the Company's consolidated financial
statements for further discussion of the non-recurring gain.

      Interest expense, net, increased $10.8 million compared to the prior
year primarily as a result of the increase in average outstanding debt
associated with the acquisition of distribution businesses acquired since
April 1, 1996, the joint venture investment in National Welders, interest
costs and debt associated with the refrigerant fraud, and the repurchase of
the Company's common stock.  As discussed in "Liquidity and Capital Resources"
below, the Company has hedged floating interest rates under certain borrowings
with interest rate swap agreements.

     Income tax expense, excluding non-recurring gains, represented 42.5% of
pre-tax earnings in the nine months ended December 31, 1997 compared to 41.7%
in the prior year. The increase in the effective income tax rate was primarily
a result of non-deductible goodwill from recent acquisitions.

LIQUIDITY AND CAPITAL RESOURCES
_______________________________

      The Company has financed its operations, capital expenditures, stock
repurchases, and acquisitions with borrowings, the issuance of common stock
and funds provided by operating activities.

      Cash flows from operating activities totaled $88 million ($73.5 million
excluding the non-recurring gain from partial recovery of refrigerant losses)
for the nine months ended December 31, 1997.  Depreciation, depletion and
amortization represent $56.8 million of cash flows from operating activities. 
Deferred income taxes of $13.8 million resulted from temporary differences. 
Cash flows from working capital components decreased $28.1 million as a result
of a decrease in accounts payable due to the timing of invoice payments, an
increase in inventory levels to meet increased sales volumes, offset by an
increase in accounts receivable associated with higher same-store sales. Days
sales outstanding improved slightly compared to the March 31, 1997 levels and
distribution hardgoods days' supply of inventory has improved approximately 8%
since March 31, 1997.  

      Cash used by investing activities totaled $204.2 million which was
primarily comprised of $93.6 million for capital expenditures, and $121.4
million related to acquisitions and investments in unconsolidated affiliates. 

      The Company's use of cash for capital expenditures was attributable to
the construction of two air separation plants, the continued assimilation of
acquisitions which require expenditures for combining cylinder fill plants,
the improvement of truck fleets, the purchase of cylinders in order to return
cylinders rented from third parties and the purchase of cylinders and bulk
tanks necessary to facilitate gas sales growth.  Through December 31, 1997,
the Company incurred capital expenditures of approximately $30.1 million
related to air separation plant construction and expects additional capital
expenditures of approximately $5 million to complete the construction of the
plants.  Both plants became operational in January 1998.  For the nine months
ended December 31, 1997, approximately $29 million of capital expenditures
were for the purchase of cylinders, bulk tanks and machinery and equipment. 
The Company estimates that its Distribution maintenance capital expenditures
are approximately 1 to 2% of net sales.  The Company considers the replacement
of existing capital assets to be maintenance capital expenditures.  

      Financing activities provided cash of $116.2 million with total debt
outstanding increasing by $172 million from March 31, 1997.  Funds from
financing activities were used primarily for acquisitions, capital
expenditures and the repurchase of Airgas common stock.

      Effective December 5, 1997, the Company entered into an amended credit
facility which replaced and combined four previous bank credit facilities. 
This amended facility consists of a US$725 million and a C$100 million
unsecured revolving credit facility with various commercial banks which
matures on December 5, 2002.  At December 31, 1997, the Company had
approximately US$438 million in borrowings and approximately C$56 million
(US$39 million)  borrowings under the facility and approximately US$99 million
committed under letters of credit, resulting in aggregate unused availability
under the facility of approximately US$221 million.  There were no other
significant changes in the terms, conditions or covenants of the amended
facility compared to the previous credit facilities.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
         OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

      In fiscal 1997, the Company commenced a medium-term note program which
provides for the issuance of its securities with an aggregate public offering
price of up to $450 million.  During fiscal 1997, the Company issued the
following long-term debt under the medium-term note program: $100 million of
unsecured notes due September 2006 bearing interest at a fixed rate of 7.75%;
$50 million of unsecured notes due September 2001 bearing interest at a fixed
rate of 7.15%; and $75 million of unsecured notes due March 2004 at a fixed
rate of 7.14%.  The proceeds from the medium-term note issuances were used to
repay bank debt. 

      At December 31, 1997, the effective interest rate related to outstanding
borrowings under all credit lines was approximately 6.38%.  The Company's loan
agreements contain covenants which include the maintenance of a minimum equity
level, maintenance of certain financial ratios, restrictions on additional
borrowings and limitations on dividends.

     In managing interest rate exposure, principally under the Company's
floating rate revolving credit facilities, the Company has entered into
25 interest rate swap agreements during the period from June 1992
through December 31, 1997.  The swap agreements are with major financial
institutions and aggregate $403 million in notional principal amount at
December 31, 1997.  Approximately $253 million of the notional principal 
amount of the swap agreements require fixed interest payments based on an
average effective rate of 6.63% for remaining periods ranging between 1 and 8
years.  Six swap agreements require floating rates ($149.5 million notional 
amount at 5.72% at December 31, 1997).  Under the terms of seven of the swap
agreements, the Company has elected to receive the discounted value of the
counterparty's interest payments upfront.  At December 31, 1997, approximately
$15.2 million of such payments were included in other liabilities.  The
Company continually monitors its positions and the credit ratings of its
counterparties, and does not anticipate nonperformance by the counterparties.

      The Company will continue to look for appropriate acquisitions and
expects to fund such acquisitions, future capital expenditure requirements and
commitments related to foreign investments primarily through the use of cash
flow from operations, debt, common stock for certain acquisition candidates
and other available sources.  Subsequent to December 31, 1997, the Company
acquired four industrial gas distributors with annual sales of approximately
$17 million, and one carbon dioxide distributor with annual sales of
approximately $5 million.

      As the Company integrates and standardizes certain information systems
during fiscal 1998, 1999 and 2000, the Company expects to enter into
obligations and purchase certain capital equipment aggregating an estimated
$18 to $24 million.  

      In October 1997, the Airgas Board of Directors approved the repurchase
of up to an additional 2,000,000 shares of common stock from time-to-time to
offset share issuances for stock options, the Employee Stock Purchase Plan,
and acquisitions.  Together with previously granted authority, this increases
the total repurchase program to a potential 4.6 million shares.  Through the
nine months ended December 31, 1997, the Company has repurchased 2,885,200
shares under previous repurchase programs.  Approximately 3 million shares
were reissued in connection with the acquisition of Carbonic Industries
Corporation and Industrial Gas Products.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
         OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

      The Company has initiated a project to integrate and standardize its
financial general ledger information systems prior to the Year 2000.  As a
result of this information system standardization, the Company expects these
systems to be Year 2000 compliant.  The Company is also conducting a
comprehensive review of its other information and operations systems to
identify the systems that may not function properly in the Year 2000 and
thereafter, and is developing an implementation plan to take appropriate
corrective action if necessary.  The Company has not yet assessed its Year
2000 compliance expense.  The Company currently believes that, with
modifications to existing software and converting to new software, the Year
2000 problem will not pose significant operational problems for the Company's
information and operations systems so modified and converted.  However, if
such modifications and conversions are not completed timely, the Year 2000
problem may have a material impact on the operations of the Company.

      The Company does not currently pay dividends.

New Accounting Pronouncements

      In the first quarter of fiscal 1998, the Company adopted SFAS No. 125,
"Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities".  This statement provides accounting and
reporting standards for transfers and servicing of financial assets and
extinguishments of liabilities based on consistent application of a financial-
components approach that focuses on control.  It distinguishes transfers of
financial assets that are sales from transfers that are secured borrowings. 
This statement is effective for transfer and servicing of financial assets and
extinguishments of liabilities for fiscal years beginning after December 15,
1996 and is to be applied prospectively.  The adoption of this statement had
no material impact on earnings, financial condition or liquidity of the
Company.

      In the first quarter of fiscal 1998, the Company adopted Statement of
Position 96-1 (SOP), which prescribes generally accepted accounting principles
for environmental remediation liabilities.  This SOP more specifically
identifies future, long-term monitoring and administration expenditures as
remediation liabilities that need to be accrued on the balance sheet as an
existing obligation.  This SOP is effective for fiscal years beginning after
December 15, 1996.  The adoption of this statement did not have a material
impact on earnings, financial condition or liquidity of the Company.

      In February 1997, the Financial Accounting Standards Board ("FASB")
issued Statement No. 128 "Earnings Per Share" (SFAS No. 128).  SFAS No. 128
establishes new standards for computing and presenting earnings per share,
effective for financial statements issued for periods ending after December
15, 1997, including interim periods.  Effective with its third quarter ended
December 31, 1997, the Company implemented SFAS No. 128.  For the Company,
Diluted earnings per share is the same as previously reported earnings per
share amounts.  All prior periods have been restated to conform to the new
rules.

      In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income."  This statement requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be

reported in a financial statement that is displayed with the same prominence
as other financial statements.  The Company plans to adopt this accounting
standard in the first quarter of fiscal 1999, as required.  The adoption of
this standard will not impact earnings, financial condition, or liquidity, but
will require the Company to classify items of other comprehensive income in a
financial statement and display the accumulated balance of other comprehensive
income separately in the equity section of the balance sheet.

      In June, 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information."  This statement establishes
standards for reporting information about operating segments in annual
financial statements and requires selected information about operating
segments in interim financial reports issued to shareholders.  It also
establishes standards for related disclosures about products and services,
geographic areas and major customers.  The Company will adopt this accounting
standard in the first quarter of fiscal 1999, as required.  The adoption of
this standard will not impact earnings, financial condition or liquidity of
the Company.

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

     On July 26, 1996, Praxair, Inc. ("Praxair") filed suit against the        
     Company in the Circuit Court of Mobile County, Alabama.  The complaint    
     alleges tortious interference with business or contractual relations with 
     respect to Praxair's Right of First Refusal contract with the majority    
     shareholders of National Welders Supply Company, Inc. ("National          
     Welders") by the Company in connection with the Company's formation of a  
     joint venture with National Welders.  Praxair is seeking compensatory     
     damages in excess of $100 million and punitive damages.  On February 24,  
     1997, the court entered an order denying the Company's motion to dismiss  
     for forum non conveniens.  The Company believes that Praxair's claims are 
     without merit and intends to defend vigorously against such claims. 

     On September 9, 1996, the Company filed suit against Praxair in the Court 
     of Common Pleas of Philadelphia County, Pennsylvania.  The complaint      
     alleges breach of contract, fraud, conversion and misappropriation of     
     trade secrets with respect to an agreement between Praxair and the        
     Company, pursuant to which Praxair induced the Company to provide         
     Praxair valuable information and conclusions developed by the Company     
     concerning CBI Industries, Inc. ("CBI") in exchange for Praxair's         
     promise not to acquire CBI without the Company's participation.  The      
     Company has alleged that it became entitled, pursuant to such agreement,  
     to acquire certain of CBI's assets having a value in excess of $800       
     million.  The Company is  seeking compensatory and punitive damages.  On  
     January 2, 1997, the court entered an order overruling Praxair's          
     preliminary objections to the Company's complaint and ordering Praxair    
     to file an answer to the complaint.  Praxair has since filed an answer    
     and asserted various defenses.  Thereafter, Praxair filed a motion for    
     judgement on the pleadings.  On July 31, 1997, the Court entered an order 
     denying that motion.

     The fraudulent breach of contract by a third-party supplier of            
     refrigerant gas was reported by the Company on December 23, 1996.  The    
     Company continues to pursue additional recoveries including proceeds      
     from insurance policies.

     2.1   Revolving U.S. Loans.

     (a)   Revolving U.S. Commitment.  Subject to the terms and conditions
hereof and in reliance upon the representations and warranties set forth
herein, each U.S. Lender severally agrees to make available to Airgas such
U.S. Lender's U.S. Commitment Percentage of revolving credit loans requested
by Airgas in U.S. Dollars ("Revolving U.S. Loans") from time to time from the
Closing Date until the Termination Date, or such earlier date as the Revolving
U.S. Commitments shall have been terminated as provided herein for the
purposes hereinafter set forth; provided, however, that the aggregate
principal amount of outstanding Revolving U.S. Loans shall not exceed SIX
HUNDRED TWENTY-FIVE MILLION U.S. DOLLARS (U.S.$625,000,000) (as such aggregate
maximum amount may be increased or reduced from time to time as provided
in Section 4.4, the "Revolving U.S. Committed Amount"); provided, further, (i)
with regard to each U.S. Lender individually, such U.S. Lender's outstanding
Revolving U.S. Loans shall not exceed such U.S. Lender's U.S. Commitment
Percentage of the Revolving U.S. Committed Amount and (ii) with regard to the
U.S. Lenders collectively, the aggregate principal amount of outstanding
Revolving U.S. Loans plus the aggregate principal amount of outstanding 

<PAGE> EX-26

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. 

Revolving U.S. Loans may consist of U.S. Base Rate Loans or Eurodollar Loans,
or a combination thereof, as Airgas may request, and may be repaid and
reborrowed in accordance with the provisions hereof; provided, however, that
no more than 11 Eurodollar Loans shall be outstanding hereunder at any time. 
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.  Revolving
U.S. Loans hereunder may be repaid and reborrowed in accordance with the
provisions hereof.

     (b)   Revolving U.S. Loan Borrowings.

           (i)   Notice of Borrowing.  Airgas (by its duly authorized officers
or representatives) shall request a Revolving U.S. Loan borrowing by written
notice (or telephone notice promptly confirmed in writing) to the U.S. Agent
not later than 11:00 A.M. (Charlotte, North Carolina time) on the Business Day
of the requested borrowing in the case of U.S. Base Rate Loans, and on the
third Business Day prior to the date of the requested borrowing in the case of
Eurodollar Loans.  Each such request for borrowing shall be irrevocable and

requested borrowing (which shall be a Business Day), (C) the aggregate
principal amount to be borrowed, and (D) whether the borrowing shall be
comprised of U.S. Base Rate Loans, Eurodollar Loans or a combination thereof,
and if Eurodollar Loans are requested, the Interest Period(s) therefor.  If
Airgas shall fail to specify in any such Notice of Borrowing (I) an applicable
Interest Period in the case of a Eurodollar Loan, then such notice shall be
deemed to be a request for an Interest Period of one month, or (II) the type
of 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.  The principal amount of all Revolving U.S. Loans shall
be due and payable in full on the Termination Date.

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

<PAGE> EX-27

           (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; and

           (ii)  Eurodollar Loans.  During such periods as Revolving U.S.

applicable Interest Payment Date (or at such other times as may be specified
herein).

     (e)   Revolving U.S. Notes.  The Revolving U.S. Loans made by each U.S.

U.S. Lender in an original principal amount equal to such U.S. Lender's U.S.
Commitment Percentage of the Revolving U.S. Committed Amount and in
substantially the form of Schedule 2.1(e).

     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 the Revolving U.S. 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 Revolving U.S.
Committed Amount.  Each Competitive U.S. Loan shall be not less than
U.S.$2,000,000 in the aggregate and integral multiples of U.S.$1,000,000 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 

<PAGE> EX-28

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. 001-641-844 maintained at the offices
of NationsBank; 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)   Competitive U.S. Notes.  The Competitive U.S. Loans of each U.S.
Lender shall be evidenced by a single Competitive U.S. Note duly executed on

     (g)   Repayment of Competitive U.S. Loans.  Airgas shall 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

U.S. Loan unless such prepayment is accompanied by payment of amounts
specified in Section 4.1.  

     (h)   Interest.  Airgas shall pay interest to each U.S. Lender on the
unpaid principal amount of each Competitive U.S. Loan of such U.S. Lender from
<PAGE> EX-29

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).

     (i)   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, 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.

     (j)   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, 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 TWO HUNDRED FIFTY MILLION U.S. DOLLARS (U.S.$250,000,000) (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 or (y) as originally issued or as extended, have an
expiry date extending beyond the Termination Date.  Each U.S. Letter of Credit
shall comply with the related U.S. LOC Documents.  The issuance and expiry
date 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
<PAGE> EX-30

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 

<PAGE> EX-31

unconditional, shall not be affected by any circumstance whatsoever and
without regard to the termination of this Credit Agreement or the Commitments
hereunder, the existence of a Default or Event of Default or the acceleration
of the obligations of Airgas hereunder and shall be made without any offset,
abatement, withholding or reduction whatsoever.  Simultaneously with the
making of each such payment by a U.S. Lender to the U.S. Issuing Lender, such
U.S. Lender shall, automatically and without any further action on the part of
the U.S. Issuing Lender or such U.S. Lender, acquire a participation in an
amount equal to such payment (excluding the portion of such payment
constituting interest owing to the U.S. Issuing Lender) in the related
unreimbursed drawing portion of the U.S. LOC Obligation and in the interest
thereon and in the related U.S. LOC Documents, and shall have a claim against
Airgas with respect thereto.

     (e)   Repayment with Revolving U.S. Loans.  On any day on which Airgas
shall have requested, or shall be deemed to have requested, a Revolving U.S.
Loan advance to reimburse a drawing under a U.S. Letter of Credit, the U.S.
Agent shall give notice to the U.S. Lenders that a Revolving U.S. Loan has
been requested or deemed requested by Airgas to be made in connection with a
drawing under a U.S. Letter of Credit, in which case a Revolving U.S. Loan
advance comprised of U.S. Base Rate Loans (or Eurodollar Loans to the extent
Airgas has complied with the procedures of Section 2.1(b)(i) with respect
thereto) shall be immediately made to Airgas by all U.S. Lenders
(notwithstanding any termination of the Commitments pursuant to Section 9.2)
pro rata based on the respective U.S. Commitment Percentages of the U.S.
Lenders (determined before giving effect to any termination of the Commitments
pursuant to Section 9.2) and the proceeds thereof shall be paid directly to
the U.S. Issuing Lender for application to the respective U.S. LOC
Obligations.  Each such U.S. Lender hereby irrevocably agrees to make its pro
rata share of each such Revolving U.S. Loan immediately upon any such request
or deemed request in the amount, in the manner and on the date specified in
the preceding sentence notwithstanding (i) the amount of such borrowing may
not comply with the minimum amount for advances of Revolving U.S. Loans
otherwise required hereunder, (ii) whether any conditions specified in Section
5.2 are then satisfied, (iii) whether a Default or an Event of Default then
exists, (iv) failure for any such request or deemed request for Revolving U.S.
Loan to be made by the time otherwise required hereunder, (v) whether the date
of such borrowing is a date on which Revolving U.S. Loans are otherwise
permitted to be made hereunder or (vi) any termination of the Commitments
relating thereto immediately prior to or contemporaneously with such
borrowing.  In the event that any Revolving U.S. Loan cannot for any reason be
made on the date otherwise required above (including, without limitation, as a
result of the commencement of a proceeding under the Bankruptcy Code with
respect to Airgas), then each such U.S. Lender hereby agrees that it shall
forthwith purchase (as of the date such borrowing would otherwise have
occurred, but adjusted for any payments received from Airgas on or after such
date and prior to such purchase) from the U.S. Issuing Lender such
participation in the outstanding U.S. LOC Obligations as shall be necessary to
cause each such U.S. Lender to share in such U.S. LOC Obligations ratably
(based upon the respective U.S. Commitment Percentages of the U.S. Lenders
(determined before giving effect to any termination of the Commitments
pursuant to Section 9.2)), provided that at the time any purchase of
participation pursuant to this sentence is actually made, the purchasing U.S.
Lender shall be required to pay to the U.S. Issuing Lender, to the extent not
paid to the Issuer by Airgas in accordance with the terms of subsection (d)
hereof, interest on the principal amount of participation purchased for each
day from and including the day upon which such borrowing would otherwise have
occurred to but excluding the date of payment for such participation, at the
rate equal to, if paid within two (2) Business Days of the date of the
Revolving U.S. Loan advance, the Federal Funds Rate, and thereafter at a rate
equal to the U.S. Base Rate.

     (f)   Designation of Subsidiaries as Account Parties.  Notwithstanding
anything to the contrary set forth in this Credit Agreement, including without
limitation Section 2.3(a) hereof, a U.S. Letter of Credit issued hereunder may
contain a statement to the effect that such U.S. Letter of Credit is issued
for the account of a Subsidiary of Airgas, provided that notwithstanding
such statement, Airgas shall be the actual account party for all purposes of
this Credit Agreement for such U.S. Letter of Credit and such statement shall
not affect Airgas' reimbursement obligations hereunder with respect to such
U.S. Letter of Credit.

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

     (h)   Uniform Customs and Practices.  The U.S. Issuing Lender may have
the U.S. Letters of Credit be subject to The Uniform Customs and Practice for
Documentary Credits, as published as of the date of issue by the International
Chamber of Commerce (the "UCP"), in which case the UCP may be incorporated
therein and deemed in all respects to be a part thereof.

     (i)   Indemnification; Nature of U.S. Issuing Lender's Duties.  

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

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

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

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

           (v)   Notwithstanding anything to the contrary contained in this
     subsection (i), Airgas shall have no obligation to indemnify the U.S.
Issuing Lender in respect of any liability incurred by the U.S. Issuing Lender
(A) arising out of the gross negligence or willful misconduct of the U.S.
Issuing Lender, or (B) caused by the U.S. Issuing Lender's failure to pay 
<PAGE> EX-33

under any U.S. Letter of Credit after presentation to it of a request strictly
complying with the terms and conditions of such U.S. Letter of Credit, as
determined by a court of competent jurisdiction, unless such payment is
prohibited by any law, regulation, court order or decree.

     (j)   Responsibility of U.S. Issuing Lender. It is expressly understood
and agreed that the obligations of the U.S. Issuing Lender hereunder to the
U.S. Lenders are only those expressly set forth in this Credit Agreement and
that the U.S. Issuing Lender shall be entitled to assume that the conditions
precedent set forth in Section 5.2 have been satisfied unless it shall have
acquired actual knowledge that any such condition precedent has not been
satisfied; provided, however, that nothing set forth in this Section 2.3 shall
be deemed to prejudice the right of any U.S. Lender to recover from the U.S.
Issuing Lender any amounts made available by such U.S. Lender to the U.S.
Issuing Lender pursuant to this Section 2.3 in the event that it is determined
by a court of competent jurisdiction that the payment with respect to a U.S.
Letter of Credit constituted gross negligence or willful misconduct on the
part of the U.S. Issuing Lender.

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

     2.4   U.S. Swingline Loan Subfacility.

     (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
FIFTEEN MILLION U.S. DOLLARS (U.S.$15,000,000) (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.

<PAGE> EX-34

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

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

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

        (A)      U.S. Base Rate Loans.  If such U.S. Swingline Loan is a 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;
and
<PAGE> EX-35

        (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.  Interest on U.S. Swingline Loans shall
be payable in arrears on each applicable Interest Payment Date (or at such
other times as may be specified herein).

     (d)   U.S. Swingline Note.  The U.S. Swingline Loans shall be evidenced
by a duly executed promissory note of Airgas to the U.S. Swingline Lender in
an original principal amount equal to the U.S. Swingline Committed Amount
substantially in the form of Schedule 2.4(d).

     2.5   364-Day Revolving Loans.

     (a)   364-Day Revolving Commitment.  Subject to the terms and conditions
hereof and in reliance upon the representations and warranties set forth
herein, each U.S. Lender severally agrees to make available to Airgas such
U.S. Lender's U.S. Commitment Percentage of 364-Day revolving credit loans
requested by Airgas in U.S. Dollars ("364-Day Revolving Loans") from
time to time from the Closing Date until the Termination Date, or such earlier
date as the 364-Day Revolving 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 364-Day
Revolving Loans shall not exceed ONE HUNDRED MILLION U.S. DOLLARS
(U.S.$100,000,000) (as such aggregate maximum amount may be reduced from time
to time as provided in Section 4.4, the "364-Day Revolving Committed Amount");
provided, further, (i) with regard to each U.S. Lender individually, such U.S.
Lender's outstanding 364-Day Revolving Loans shall not exceed such U.S.
Lender's U.S. Commitment Percentage of the 364-Day Revolving Committed Amount
and (ii) the aggregate principal amount of outstanding 364-Day Revolving Loans
shall not exceed the 364-Day Revolving Committed Amount.  364-Day Revolving
Loans may consist of U.S. Base Rate Loans or Eurodollar Loans, or a
combination thereof, as Airgas may request, and may be repaid and reborrowed
in accordance with the provisions hereof; provided, however, that no more than
11 Eurodollar Loans shall be outstanding hereunder at any time.  For purposes
hereof, Eurodollar Loans with different Interest Periods shall be considered
as separate Eurodollar Loans, even if they begin on the same date, although
borrowings, extensions and conversions may, in accordance with the provisions
hereof, be combined at the end of existing Interest Periods to constitute a
new Eurodollar Loan with a single Interest Period.  364-Day Revolving Loans
hereunder (other than any 364-Day Revolving Loans which have been converted to
term loans pursuant to Section 2.5(f)) may be repaid and reborrowed in
accordance with the provisions hereof.

     (b)   364-Day Revolving Loan Borrowings.

           (i)   Notice of Borrowing.  Airgas (by its duly authorized officers
or representatives) shall request a 364-Day Revolving Loan borrowing by
written notice (or telephone notice promptly confirmed in writing) to the U.S.
Agent not later than 11:00 A.M. (Charlotte, North Carolina time) on the
Business Day of the requested borrowing in the case of U.S. Base Rate Loans,
and on the third Business Day prior to the date of the requested borrowing in
the case of Eurodollar Loans.  Each such request for borrowing shall be 

<PAGE> EX-36

irrevocable and shall specify (A) that a 364-Day Revolving Loan is requested,
(B) the date of the requested borrowing (which shall be a Business Day), (C)
the aggregate principal amount to be borrowed, and (D) whether the borrowing
shall be comprised of U.S. Base Rate Loans, Eurodollar Loans or a combination
thereof, and if Eurodollar Loans are requested, the Interest Period(s)
therefor.  If Airgas shall fail to specify in any such Notice of Borrowing (I)
an applicable Interest Period in the case of a Eurodollar Loan, then such
notice shall be deemed to be a request for an Interest Period of one month, or
(II) the type of 364-Day Revolving Loan requested, then such notice shall be
deemed to be a request for a U.S. Base Rate Loan hereunder.  The U.S. Agent
shall give notice to each affected U.S. Lender promptly upon receipt of each
Notice of Borrowing pursuant to this Section 2.5(b)(i), specifying the
contents thereof and each such U.S. Lender's share of any borrowing to be made
pursuant thereto.

           (ii)  Minimum Amounts.  Each Eurodollar Loan or U.S. Base Rate Loan
that is a 364-Day Revolving Loan shall be in a minimum aggregate principal
amount of U.S.$5,000,000 and integral multiples of U.S.$1,000,000 in excess
thereof (or the remaining amount of the 364-Day Revolving Committed Amount, if
less).

           (iii) Advances.  Each U.S. Lender will make its U.S. Commitment
Percentage of each 364-Day Revolving 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.  The principal amount of all 364-Day Revolving Loans
shall be due and payable in full on the Termination Date applicable to
Revolving U.S. Loans.

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

           (i)   U.S. Base Rate Loans.  During such periods as 364-Day
Revolving 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; and

           (ii)  Eurodollar Loans.  During such periods as 364-Day Revolving
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.

Interest on 364-Day Revolving Loans shall be payable in arrears on each
applicable Interest Payment Date (or at such other times as may be specified
herein).

     (e)   364-Day Revolving Notes.  The 364-Day Revolving Loans made by each
U.S. Lender shall be evidenced by a duly executed promissory note of Airgas to
such U.S. Lender in an original principal amount equal to such U.S. Lender's
U.S. Commitment Percentage of the 364-Day Revolving Committed Amount and in
substantially the form of Schedule 2.5(e).




<PAGE> EX-37

     (f)   Extension of 364-Day Revolving Loan Facility.  Upon written request
of Airgas delivered to the U.S. Agent not more than 60 days nor less than 30
days prior to the then current Termination Date for 364-Day Revolving Loans,
each U.S. Lender in its sole discretion may (but shall not be obligated to)
agree by not more than 30 days prior to the then current Termination
Date to extend the then effective Termination Date with respect to such U.S.
Lender's 364-Day Revolving Commitment for a period of 364-days (an "Extending
U.S. Lender").  Any failure to respond or failure to provide an affirmative
response shall be deemed to be a response in the negative to such request.  In
the event that any U.S. Lender chooses to extend the Termination Date for such
a 364-day period, notice shall be given by the U.S. Agent to Airgas no more
than 30 nor less than 25 days prior to the then effective Termination Date. 
The principal amounts of all outstanding 364-Day Revolving Loans representing
364-Day Revolving Commitments of U.S. Lenders not extending their respective
Commitments pursuant to this Section 2.5(f) shall convert into term loans
which shall be due and payable in accordance with Section 2.5(c).  The
principal amounts of all outstanding 364-Day Revolving Loans representing
364-Day Revolving Commitments of U.S. Lenders electing to extend their
respective Commitments pursuant to this Section 2.5(f) shall, at the end of
the extension period, convert into term loans which shall be due and payable
in accordance with Section 2.5(c).

the Canadian Borrowers in Canadian Dollars ("Revolving Canadian Loans") from

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

           (iii) Advances.  Each Canadian Lender will make its Canadian

     (e)   Revolving Canadian Notes.  The Revolving Canadian Loans made by
each Canadian Lender shall be evidenced by a duly executed promissory note of
the particular Canadian Borrower to such Canadian Lender in an original

Percentage  of the Revolving Canadian Committed Amount and in substantially
the form of Schedule 3.1(e).

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

operating accounts maintained by such Canadian Borrower with the Canadian
Swingline Lender (collectively, the "Operating Accounts"), for the purposes 

<PAGE> EX-39

hereinafter set forth; provided, however, (A) the aggregate principal amount
of Canadian Swingline Loans outstanding at any time shall not exceed FIVE
MILLION CANADIAN DOLLARS (C$5,000,000) (the "Canadian Swingline Committed
Amount"), and (B) the aggregate principal amount of outstanding Revolving
Canadian Loans plus the aggregate principal amount of outstanding Canadian
Swingline Loans plus Canadian LOC Obligations outstanding plus the BA
Outstandings shall not exceed the Revolving Canadian Committed Amount.  Unless
the Canadian Borrowers have made prior arrangements with the Canadian
Swingline Lender (including without limitation by requesting a Revolving
Canadian Loan), the Canadian Swingline Lender may return any debit from an
Operating Account that, if paid, would result in the aggregate principal
amount of outstanding Canadian Swingline Loans exceeding the Canadian
Swingline Committed Amount if (1) any Default or Event of Default then exists
or (2) if the applicable Canadian Borrower does not, on or before the first
Business Day after receipt by such Canadian Borrower of notice of such excess
from the Canadian Swingline Lender, deposit money or request a Revolving
Canadian Loan sufficient to cover such debit.  Canadian Swingline Loans
hereunder may be repaid and reborrowed in accordance with the provisions
hereof.

     (b)   Repayment of Canadian Swingline Loans.  Each Canadian Borrower
hereby promises to repay the principal amount of each Canadian Swingline Loan
taken by such Canadian Borrower on the earlier of (A) the maturity date agreed
to by the Canadian Swingline Lender and such Canadian Borrower with respect to
such Canadian Swingline Loan or (B) the Termination Date.  The Canadian
Swingline Lender may, at any time, in its sole discretion, by written notice
to the Canadian Borrower and the Canadian Lenders, demand repayment of its
Canadian Swingline Loans by way of a Revolving Canadian Loan advance, in which
case the Canadian Borrower shall be deemed to have requested a Revolving
Canadian Loan advance in the amount of such Canadian Swingline Loans;
provided, however, that such a demand shall be deemed to have been given one
Business Day prior to the Termination Date and on the date of the occurrence
of any Event of Default described in Section 9.1 (or if such date is not a
Business Day, the first Business Day succeeding such date) and upon
acceleration of the indebtedness hereunder and the exercise of remedies in
accordance with the provisions of Section 9.2.  Each Canadian Lender hereby
irrevocably agrees to make its pro rata share of each such Revolving Canadian
Loan in the amount, in the manner and on the date specified in the preceding

the minimum amount for advances of Revolving Canadian Loans otherwise required
hereunder, (II) whether any conditions specified in Section 5.2 are then
satisfied, (III) whether a Default or an Event of Default then exists, (IV)
failure of any such request or deemed request for a Revolving Canadian
Loan to be made by the time otherwise required hereunder, (V) whether the date
of such borrowing is a date on which Revolving Canadian Loans are otherwise
permitted to be made hereunder or (VI) any termination of the Commitments
relating thereto immediately prior to or contemporaneously with such
borrowing.

           (c)   Interest on Canadian Swingline Loans.
     
           (i)   Interest Rate.  Subject to the provisions of Section 4.1,
each Canadian Swingline Loan shall bear interest at a per annum rate (computed
on the basis of the actual number of days elapsed over a year of 365 days)
equal to the Canadian Base Rate; and

           (ii)  Payment of Interest.  With respect to each Canadian Swingline
Loan taken by a Canadian Borrower, such Canadian Borrower hereby promises to

     3.3   Canadian Letter of Credit Subfacility.

     (a)   Issuance.  Subject to the terms and conditions hereof and of the
Canadian LOC Documents, if any, and any other terms and conditions which the
Canadian Issuing Lender may reasonably require, the Canadian Lenders will
participate in the issuance by the Canadian Issuing Lender from time to time
of such Canadian Letters of Credit in Canadian Dollars from the Closing Date
until the Termination Date as a Canadian Borrower may request, in a form
acceptable to the Canadian Issuing Lender; provided, however, that (i) the
Canadian LOC Obligations outstanding shall not at any time exceed FIFTY
MILLION CANADIAN DOLLARS (C$50,000,000) (the "Canadian LOC Committed Amount")
and (ii) the sum of the aggregate principal amount of outstanding Canadian
Revolving Loans plus the aggregate principal amount of outstanding Canadian
Swingline Loans plus Canadian LOC Obligations outstanding plus BA Outstandings
shall not at any time exceed the aggregate Revolving Canadian Committed
Amount.  No Canadian Letter of Credit shall (x) have an original expiry date
more than one year from the date of issuance or (y) as originally issued or as
extended, have an expiry date extending beyond the Termination Date.  Each
Canadian Letter of Credit shall comply with the related Canadian LOC
Documents.  The issuance and expiry date of each Canadian Letter of Credit
shall be a Business Day.

     (b)   Notice and Reports.  The request for the issuance of a Canadian
Letter of Credit shall be submitted by the applicable Canadian Borrower (by
its duly authorized officers or representatives) to the Canadian Issuing
Lender at least three (3) Business Days prior to the requested date of
issuance.  The Canadian Issuing Lender will, at least quarterly and more
frequently upon request, disseminate to each of the Canadian Lenders a
detailed report specifying the Canadian Letters of Credit which are then
issued and outstanding and any activity with respect thereto which may have
occurred since the date of the prior report, and including therein, among
other things, the beneficiary, the face amount and expiry date as well as any
payments or expirations which may have occurred.

     (c)   Participation.  Each Canadian Lender, upon issuance of a Canadian
Letter of Credit (or, in the case of each Existing Canadian Letter of Credit,
on the Closing Date), shall be deemed to have purchased without recourse a
risk participation from the Canadian Issuing Lender in such Canadian Letter of
Credit and the obligations arising thereunder, in each case in an amount equal
to its pro rata share of the obligations under such Canadian Letter of Credit
(based on the respective Canadian Commitment Percentages of the Canadian
Lenders) and shall absolutely, unconditionally and irrevocably assume, as
primary obligor and not as surety, and be obligated to pay to the Canadian
Issuing Lender therefor and discharge when due, its pro rata share of the
obligations arising under such Canadian Letter of Credit.  Without limiting
the scope and nature of each Canadian Lender's participation in any Canadian
Letter of Credit, to the extent that the Canadian Issuing Lender has not been
reimbursed as required hereunder or under any such Canadian Letter of Credit,
each such Canadian Lender shall pay to the Canadian Issuing Lender its pro
rata share of such unreimbursed drawing pursuant to the provisions of
subsection (d) hereof.  The obligation of each Canadian Lender to so reimburse
the Canadian Issuing Lender shall be absolute and unconditional and shall not
be affected by the occurrence of a Default, an Event of Default or any other
occurrence or event.  Any such reimbursement shall not relieve or otherwise
impair the obligation of each Canadian Borrower to reimburse the Canadian
Issuing Lender under any Canadian Letter of Credit issued for the account of
such Canadian Borrower, together with interest as hereinafter provided.

     (d)   Reimbursement.  In the event of any drawing under any Canadian
Letter of Credit, the Canadian Issuing Lender will promptly notify the
applicable Canadian Borrower.  Unless the applicable Canadian Borrower shall 

<PAGE> EX-41

immediately notify the Canadian Issuing Lender that such Canadian Borrower
intends to otherwise reimburse the Canadian Issuing Lender for such drawing,
such Canadian Borrower shall be deemed to have requested that the Canadian
Lenders make a Revolving Canadian Loan in the amount of the drawing as
provided in subsection (e) hereof on the related Canadian Letter of Credit,
the proceeds of which will be used to satisfy the related reimbursement
obligations.  Each Canadian Borrower promises to reimburse  the Canadian
Issuing Lender on the day of drawing under any Canadian Letter of Credit
issued for the account of such Canadian Borrower (either with the proceeds of
a Revolving Canadian Loan obtained hereunder or otherwise) in same day funds. 
If the applicable Canadian Borrower shall fail to reimburse the Canadian
Issuing Lender (either with the proceeds of a Revolving Canadian Loan obtained
hereunder or otherwise), the unreimbursed amount of such drawing shall bear
interest at a per annum rate equal to the Canadian Base Rate plus two percent
(2%).  The reimbursement obligations of each Canadian Borrower hereunder shall
be absolute and unconditional under all circumstances irrespective of any
rights of setoff, counterclaim or defense to payment such Canadian Borrower
may claim or have against the Canadian Issuing Lender, the U.S. Agent, the
Canadian Agent, the Canadian Lenders, the beneficiary of the Canadian Letter
of Credit drawn upon or any other Person, including without limitation any
defense based on any failure of such Canadian Borrower to receive
consideration or the legality, validity, regularity or unenforceability
of the Canadian Letter of Credit. The Canadian Issuing Lender will promptly
notify the other Canadian Lenders of the amount of any unreimbursed drawing
under any Canadian Letter of Credit and each Canadian Lender shall promptly
pay to the Canadian Agent for the account of the Canadian Issuing Lender in
Canadian Dollars and in immediately available funds, the amount of such
Canadian Lender's pro rata share of such unreimbursed drawing.  Such payment
shall be made on the day such notice is received by such Canadian Lender from
the Canadian Issuing Lender if such notice is received at or before 2:00 P.M.
(Toronto, Canada time) otherwise such payment shall be made at or before 12:00
NOON (Toronto, Canada time) on the Business Day next succeeding the day such
notice is received.  If such Canadian Lender does not pay such amount to the
Canadian Issuing Lender in full upon such request, such Canadian Lender shall,
on demand, pay to the Canadian Agent for the account of the Canadian Issuing
Lender interest on the unpaid amount during the period from the date of such
drawing until such Canadian Lender pays such amount to the Canadian Issuing
Lender in full at a rate per annum equal to the Canadian Base Rate.  Each
Canadian Lender's obligation to make such payment to the Canadian Issuing
Lender, and the right of the Canadian Issuing Lender to receive the same,
shall be absolute and unconditional, shall not be affected by any circumstance
whatsoever and without regard to the termination of this Credit Agreement or
the Commitments hereunder, the existence of a Default or Event of Default or
the acceleration of the obligations of Airgas hereunder and shall be made
without any offset, abatement, withholding or reduction whatsoever. 
Simultaneously with the making of each such payment by a Canadian Lender to
the Canadian Issuing Lender, such Canadian Lender shall, automatically and
without any further action on the part of the Canadian Issuing Lender or such
Canadian Lender, acquire a participation in an amount equal to such payment
(excluding the portion of such payment constituting interest owing to the
Canadian Issuing Lender) in the related unreimbursed drawn portion of the
Canadian LOC Obligation and in the interest thereon and in the related
Canadian LOC Documents, and shall have a claim against the Canadian Borrower
with respect thereto.

     (e)   Repayment with Revolving Canadian Loans.  On any day on which a
Canadian Borrower shall have requested, or shall be deemed to have requested,
a Revolving Canadian Loan advance to reimburse a drawing under a Canadian
Letter of Credit, the Canadian Agent shall give notice to the Canadian Lenders
that a Revolving Canadian Loan  advance has been requested or deemed requested
by such Canadian Borrower to be made in connection with a drawing under a 

<PAGE> EX-42

Canadian Letter of Credit, in which case a Revolving Canadian Loan shall be
immediately made to such Canadian Borrower by all Canadian Lenders
(notwithstanding any termination of the Commitments pursuant to Section 9.2)
pro rata based on the respective Canadian Commitment Percentages of the
Canadian Lenders (determined before giving effect to any termination of the
Commitments pursuant to Section 9.2)  and the proceeds thereof shall be paid
directly to the Canadian Issuing Lender for application to the respective
Canadian LOC Obligations.  Each such Canadian Lender hereby irrevocably agrees
to make its pro rata share of each such Revolving Canadian Loan immediately
upon any such request or deemed request in the amount, in the manner and on
the date specified in the preceding sentence notwithstanding (i) the amount of
such borrowing may not comply with the minimum amount for advances of
Revolving Canadian Loans otherwise required hereunder, (ii) whether any
conditions specified in Section 5.2 are then satisfied, (iii) whether a
Default or an Event of Default then exists, (iv) that any such request or
deemed request for Revolving Canadian Loan is not made by the time otherwise
required hereunder, (v) whether the date of such borrowing is a date on which
Revolving Canadian Loans are otherwise permitted to be made hereunder or (vi)
any termination of the Commitments relating thereto immediately prior to or
contemporaneously with such borrowing.  In the event that any Revolving
Canadian Loan cannot for any reason be made on the date otherwise required
above (including, without limitation, as a result of the commencement of a
proceeding under the Bankruptcy Code with respect to a  Canadian Borrower or
Airgas), then each such Canadian Lender hereby agrees that it shall forthwith
purchase (as of the date such borrowing would otherwise have occurred, but
adjusted for any payments received from any Canadian Borrower on or after such
date and prior to such purchase) from the Canadian Issuing Lender such
participation in the outstanding Canadian LOC Obligations as shall be
necessary to cause each such Canadian Lender to share in such Canadian LOC
Obligations ratably (based upon the respective Canadian Commitment Percentages
of the Canadian Lenders (determined before giving effect to any termination of
the Commitments pursuant to Section 9.2)), provided that at the time any
purchase of participation pursuant to this sentence is actually made, the
purchasing Canadian Lender shall be required to pay to the Canadian Issuing
Lender, to the extent not paid to the Issuer by Airgas in accordance with the
terms of subsection (d) hereof, interest on the principal amount of
participation purchased for each day from and including the day upon which
such borrowing would otherwise have occurred to but excluding the date of
payment for such participation, at a rate equal to the Canadian Base Rate.

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

     (g)   Uniform Customs and Practices.  The Canadian Issuing Lender may
have the Canadian Letters of Credit be subject to The Uniform Customs and
Practice for Documentary Credits, as published as of the date of issue by the
International Chamber of Commerce (the "UCP"), in which case the UCP shall be
expressly incorporated therein and deemed in all respects to be a part
thereof.

     (h)   Indemnification; Nature of Canadian Issuing Lender's Duties.  

           (i)   Each Canadian Borrower agrees to indemnify and hold harmless
the Canadian Issuing Lender, each other Canadian Lender, the Canadian Agent,
the U.S. Agent and each of their respective officers, directors, affiliates,
employees or agents (the "Indemnitees") from and against any and all claims
and damages, losses, liabilities, costs and expenses which the Indemnitees may
incur (or which may be claimed against any Indemnitee) by any Person by reason
of or in connection with the issuance or transfer of or payment or failure to
pay under any Canadian Letter of Credit issued for the account of such 

<PAGE> EX-43

Canadian Borrower; provided that the Canadian Borrowers shall not be required
to indemnify the Indemnitees for any claims, damages, losses, liabilities,
costs or expenses to the extent, but only to the extent, (A) caused by the
willful misconduct or gross negligence of any Indemnitee in determining
whether a request presented under any Canadian Letter of Credit complied with
the terms of such Canadian Letter of Credit or (B) caused by the Canadian
Issuing Lender's failure to pay under any Canadian Letter of Credit after the
presentation to it of a request strictly complying with the terms and
conditions of such Canadian Letter of Credit (unless such payment is
prohibited by any law, regulation, court order or decree).

           (ii)  Each Canadian Borrower agrees, as between such Canadian
     Borrower and the Canadian Issuing Lender, such Canadian Borrower shall
assume all risks of the acts, omissions or misuse by the beneficiary of any
Canadian Letter of Credit issued for the account of such Canadian Borrower.



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

           (iv)  Nothing in this subsection (h) is intended to limit the
reimbursement obligations of the Canadian Borrowers contained in subsection
(d) above.  The obligations of the Canadian Borrowers under this subsection
(h) shall survive the termination of this Credit Agreement.  No acts or
omissions of any current or prior beneficiary of a Canadian Letter of Credit
shall in any way affect or impair the rights of the Canadian Issuing Lender to
enforce any right, power or benefit under this Credit Agreement.

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

     (i)   Responsibility of Canadian Issuing Lender.  It is expressly
understood and agreed that the obligations of the Canadian Issuing Lender
hereunder to the Canadian Lenders are only those expressly set forth in this
Credit Agreement and that the Canadian Issuing Lender shall be entitled to
assume that the conditions precedent set forth in Section 5.2 have been
satisfied unless it shall have acquired actual knowledge that any such
condition precedent has not been satisfied; provided, however, that nothing
set forth in this Section 3.3 shall be deemed to prejudice the right of any
Canadian Lender to recover from the Canadian Issuing Lender any amounts made
available by such Canadian Lender to the Canadian Issuing Lender pursuant to
this Section 3.3 in the event that it is determined by a court of competent
jurisdiction that the payment with respect to a Canadian Letter of Credit
constituted gross negligence or willful misconduct on the part of the Canadian
Issuing Lender.

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

     3.4   Bankers' Acceptances.

     (a)   Issuance.  Subject to the terms and conditions hereof and any other
terms and conditions which a Canadian Lender may reasonably require (so long
as such terms and conditions do not impose any financial obligation on or
require any Lien (not otherwise contemplated by this Credit Agreement) to be
given by any Consolidated Party or conflict with any obligation of, or detract
from any action which may be taken by, any Canadian Borrower under this Credit
Agreement), each Canadian Lender agrees, severally and not jointly, at any
time and from time to time from the Closing Date to the Termination Date, to
create Bankers' Acceptances by accepting drafts of a Canadian Borrower
presented to it for acceptance in an amount equal to such Canadian Lender's
Commitment Percentage of such Bankers' Acceptances as a Canadian Borrower may
request on such date; provided, however, that the aggregate amount of
Revolving Canadian Loans outstanding plus the aggregate principal amount of
outstanding Canadian Swingline Loans plus Canadian LOC Obligations outstanding
plus the BA Outstandings may not exceed the Revolving Canadian Committed
Amount.  Upon the acceptance of any draft of a Canadian Borrower pursuant
hereto, such Canadian Borrower shall pay to the Canadian Lender accepting the
same, in advance, the Acceptance Fee.  Forthwith after each request for
drawdown of, continuation of or conversion into Banker's Acceptances, the
Canadian Agent shall notify each Canadian Lender of the amount and
denomination of the Bankers' Acceptances to be accepted by such Canadian
Lender.  Canadian Borrower shall as soon as practical deliver to the
Canadian Agent a notice confirming the issuance of Bankers' Acceptances drawn
by it and specifying the net proceeds derived therefrom.  For greater
certainty, with respect to each extension of credit by way of Bankers'
Acceptances from the Canadian Lenders, each Bankers' Acceptance shall have the
same term.

     (b)   General Provisions regarding Bankers' Acceptances.  

     (i)   Any draft tendered by a Canadian Borrower for acceptance by a
Canadian Lender shall be payable in Canada, shall be in the standard form of
bankers' acceptance accepted by such Canadian Lender and shall have a term
ending on a Business Day not less than 30 days (or any earlier date, subject
to availability) or more than 180 days from the date of acceptance.  Each
extension of credit by way of Bankers' Acceptances from the Canadian Lenders
shall be for the minimum aggregate principal amount of C$1,500,000 and in
multiples of C$100,000.

     (ii)  On presentation of a draft for acceptance the applicable Canadian
Borrower shall pay to the applicable Canadian Lender a stamping fee calculated
on the principal amount and for the term of the draft equal to the Applicable
Percentage.

     (iii) All Bankers' Acceptances to be accepted by the Canadian Lenders
shall be obtained through the Canadian Agent.  Each Canadian Lender agrees to
purchase at the Discount Rate each Bankers' Acceptance accepted by it and to
provide to the Canadian Agent for the account of the applicable Canadian
Borrower the discount proceeds less the stamping fee.  A Canadian Lender may
hold, sell, rediscount or otherwise dispose of any or all Bankers' Acceptances
accepted and purchased by it.

     (iv)  The applicable Canadian Borrower shall provide for each of the
Bankers' Acceptances at their respective maturities at the Canadian Agent's
main branch in Toronto, Canada (either with the proceeds of a Revolving
Canadian Loan obtained hereunder or otherwise).  The Canadian Borrowers will
continue to be required to provide as aforesaid for each of the Bankers'
Acceptances at maturity notwithstanding the fact that the applicable
Canadian Lender may be the holder of a Bankers' Acceptance previously issued 

<PAGE> EX-45

by that Canadian Lender.  Any amount owing in respect of any Bankers'
Acceptance which is not paid in accordance with the foregoing shall be subject
to the same terms as are applicable to Canadian Base Rate Loans, but be
payable on demand.

     (v)   In the event that demand is made on the Canadian Borrowers pursuant
to Section 9.2, the Canadian Borrowers who have then outstanding any Bankers'
Acceptance(s) shall forthwith pay to the Canadian Lenders an amount equal to
each such Canadian Lender's maximum potential liability under outstanding
Bankers' Acceptances stamped by it on behalf of the applicable Canadian
Borrower.  Such amount shall be held by the Canadian Lenders for set-off
against future indebtedness owing by the applicable Canadian Borrower to the
Canadian Lenders in respect of such Bankers' Acceptance(s).

     (vi)  Each Canadian Borrower shall supply the Canadian Lenders with such
number of drafts executed and endorsed on behalf of such Canadian Borrower (by
its duly authorized officers or other representatives) (or by duly authorized
officers or other representatives of Airgas) as the Canadian Lenders may from
time to time reasonably request.  The signatures of such officers may be
mechanically reproduced in facsimile and such facsimile signatures shall
be valid and binding on such Canadian Borrower as if they had been manually
signed by such officers.  Notwithstanding that any of the individuals whose
manual or facsimile signature appears on any draft may no longer hold office
at the date thereof or at the date of its acceptance by a Canadian Lender
hereunder or at any time thereafter, any draft or Bankers' Acceptance signed
as provided for in this Section 3.4 shall be valid and binding on the
applicable Canadian Borrower.  The Canadian Lenders will not be liable for
their failure to accept drafts pursuant to this Credit Agreement if such
failure is, in whole or in part, due to the failure of a Canadian Borrower to
provide drafts to a Canadian Lender in accordance with this Section 3.4.  The
responsibility of a Canadian Lender in respect of the safekeeping of executed
drafts which are delivered to it for acceptance hereunder shall be limited to
the exercise of the same degree of care which such Canadian Lender gives to
its own property, provided that such Canadian Lender shall not be deemed to be
an insurer thereof.  Each of the Canadian Borrowers hereby confirms each of
the Canadian Lenders shall be entitled to rely upon instructions provided by
Airgas regarding the completion of drafts which are delivered to it for
acceptance on behalf of any Canadian Borrower hereunder.

     (vii) Each Canadian Borrower shall ensure that no Bankers' Acceptance it
draws has a maturity date beyond the Termination Date.

     3.5   Guaranty of Canadian Borrowers' Obligations.

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



<PAGE> EX-46

     (b)   Obligations Unconditional.  The obligations of the Guarantor under
Section 3.5(a) are absolute and unconditional, irrespective of the value,
genuineness, validity, regularity or enforceability of any of the Credit
Documents, or any other agreement or instrument referred to therein, or any
substitution, release, impairment or exchange of any other guarantee of or
security for any of the Canadian Borrower Obligations, and, to the fullest
extent permitted by applicable law, irrespective of any other circumstance
whatsoever which might otherwise constitute a legal or equitable discharge or
defense of a surety or guarantor, it being the intent of this Section
3.5(b) that the obligations of the Guarantor hereunder shall be absolute and
unconditional under any and all circumstances.  The Guarantor agrees that it
shall have no right of subrogation, indemnity, reimbursement or contribution
against any Canadian Borrower or any other guarantor of the Canadian Borrower
Obligations for amounts paid under this Section 3.5 until such time as the
Lenders have been paid in full, all Commitments under this Credit Agreement
have been terminated and no Person or Governmental Authority shall have any
right to request any return or reimbursement of funds from the Lenders in
connection with monies received under the Credit Documents.  Without limiting
the generality of the foregoing, it is agreed that, to the fullest extent
permitted by law, the occurrence of any one or more of the following shall not
alter or impair the liability of the Guarantor hereunder which shall remain
absolute and unconditional as described above:


           (i)   at any time or from time to time, without notice to the
Guarantor, the time for any performance of or compliance with any of the
Canadian Borrowers' Obligations shall be extended, or such performance or
compliance shall be waived;

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

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

           (iv)  any of the Canadian Borrowers' Obligations shall be
determined to be void or voidable (including, without limitation, for the
benefit of any creditor of the Guarantor) or shall be subordinated to the
claims of any Person (including, without limitation, any creditor of the
Guarantor).
     
     With respect to its obligations hereunder, the Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Agent or any Lender exhaust any
right, power or remedy or proceed against any Person under any of the Credit
Documents or any other agreement or instrument referred to in the Credit
Documents, or against any other Person under any other guarantee of, or
security for, any of the Canadian Borrowers' Obligations.

     (c)   Reinstatement.  The obligations of the Guarantor under this Section
3.5 shall be automatically reinstated if and to the extent that for any reason
any payment by or on behalf of any Person in respect of the Canadian
Borrowers' Obligations is rescinded or must be otherwise restored by any
holder of any of the Canadian Borrowers' Obligations, whether as a result of
any proceedings in bankruptcy or reorganization or otherwise, and the 

<PAGE> EX-47

Guarantor agrees that it will indemnify the Canadian Agent and each Canadian
Lender on demand for all reasonable costs and expenses (including, without
limitation, fees and expenses of counsel) incurred by the Canadian
Agent or such Canadian Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending
against any claim alleging that such payment constituted a preference,
fraudulent transfer or similar payment under any bankruptcy, insolvency
or similar law.

     (d)   Certain Additional Waivers.  Without limiting the generality of the
provisions of this Section 3.5, the Guarantor hereby specifically waives the
benefits of N.C. Gen. Stat. Sections 26-7 through 26-9, inclusive, to the extent
applicable.  The Guarantor further agrees that it shall have no right of
recourse to security for the Canadian Borrowers' Obligations, except through
the exercise of the rights of subrogation pursuant to Section 3.5(b).

     (e)   Remedies.  The Guarantor agrees that, to the fullest extent
permitted by law, as between the Guarantor, on the one hand, and the Canadian
Agent and the Canadian Lenders, on the other hand, the Canadian Borrowers'
Obligations may be declared to be forthwith due and payable as provided in
Section 9.2 (and shall be deemed to have become automatically due and
payable in the circumstances provided in said Section 9.2) for purposes of
Section 3.5(a) notwithstanding any stay, injunction or other prohibition
preventing such declaration (or preventing the Canadian Borrowers' Obligations
from becoming automatically due and payable) as against any other Person and
that, in the event of such declaration (or the Canadian Borrowers'
Obligations being deemed to have become automatically due and payable), the
Canadian Borrowers' Obligations (whether or not due and payable by any other
Person) shall forthwith become due and payable by the Guarantor for purposes
of Section 3.5(a).

     (f)   Guarantee of Payment; Continuing Guarantee.  The guarantee in this
Section 3.5 is a guaranty of payment and not of collection, is a continuing
guarantee, and shall apply to all Canadian Borrowers' Obligations whenever
arising.

     3.6   Reset Mechanism.

     Each Canadian Lender agrees that it will, at any time or from time to
time, upon the request of the Canadian Agent, purchase portions of the
outstanding Revolving Canadian Loans, Canadian Swingline Loans, Canadian LOC
Obligations and BA Outstandings made available by the other Canadian Lenders
hereunder and make any other adjustments which may be necessary or
appropriate, in order that the amount of such outstanding Revolving Canadian
Loans, Canadian Swingline Loans, Canadian LOC Obligations and BA Outstandings
made available by the respective Canadian Lenders, as adjusted pursuant to
this Section 3.6, will be in the same proportions as the amount which each
Canadian Lender's Canadian Commitment Percentage bears to the total Canadian
Commitment Percentages of all the Canadian Lenders.


SECTION 4

OTHER PROVISIONS RELATING TO CREDIT FACILITIES

     4.1   Default Rate.

     Upon the occurrence, and during the continuance, of an Event of Default,
the principal of and, to the extent permitted by law, interest on the Loans
and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate 2% greater than 

<PAGE> EX-48

the rate which would otherwise be applicable (or if no rate is applicable,
whether in respect of interest, fees or other amounts, then 2% greater than
the U.S. Base Rate).

     4.2   Extension and Conversion.

     (a) Airgas.  Subject to the terms of Section 5.2, Airgas shall have the
option, on any Business Day, to extend existing Revolving U.S Loans or 364-Day
Revolving Loans into a subsequent permissible Interest Period or to convert
any such Loans into Loans of another interest rate type; provided, however,
that (i) except as provided in Section 4.8, Eurodollar Loans may be converted
into U.S. Base Rate Loans only on the last day of the Interest Period
applicable thereto, (ii) Eurodollar Loans may be extended, and U.S. Base Rate
Loans may be converted into Eurodollar Loans, only if no Default or Event of
Default is in existence on the date of extension or conversion, (iii) Loans
extended as, or converted into, Eurodollar Loans shall be subject to the
terms of the definition of "Interest Period" set forth in Section 1.1 and
shall be in such minimum amounts as provided in Sections 2.1(b)(ii),
2.5(b)(ii) and 3.1(b)(ii), (iv) no more than 11 Eurodollar Loans shall be
outstanding hereunder at any time (it being understood that, for purposes
hereof, Eurodollar Loans with different Interest Periods shall be considered
as separate Eurodollar Loans, even if they begin on the same date, although
borrowings, extensions and conversions may, in accordance with the provisions
hereof, be combined at the end of existing Interest Periods to constitute a
new Eurodollar Loan with a single Interest Period), (v) any request for
extension or conversion of a Eurodollar Loan which shall fail to specify an
Interest Period shall be deemed to be a request for an Interest Period of one
month and (vi) Competitive U.S. Loans and U.S. Swingline Loans may not be
extended or converted pursuant to this Section 4.2.  Each such extension or
conversion shall be effected by Airgas by giving a Notice of
Extension/Conversion (or telephone notice promptly confirmed in writing) to 
the U.S. Agent prior to 11:00 A.M. (Charlotte, North Carolina time) on the
Business Day of, in the case of the conversion of a Eurodollar Loan into a

shall constitute a representation and warranty by Airgas of the matters
specified in subsections (ii), (iii), (iv) and (v) of Section 5.2.  In the
event Airgas fails to request extension or conversion of any Eurodollar Loan

Borrower must comply with all the requirements of Section 3.4, and (iii)
failure by such Canadian Borrower to properly continue a Bankers' Acceptance

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 Credit Parties, the Credit Parties 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 Credit Parties 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 

<PAGE> EX-55

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 

<PAGE> EX-56

Governmental Authority, in each case made subsequent to the Closing Date (or,
if later, the date on which such Lender becomes a Lender):

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

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

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

     4.10  Taxes.

     (a)   Except as provided below in this subsection, all payments made by
the Credit Parties under this Credit Agreement and any Notes shall be made
free and clear of, and without deduction or withholding for or on account of,
any present or future income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any court, or governmental body, agency or
other official, excluding taxes measured by or imposed upon the overall net
income of any Lender or its applicable lending office, or any branch or
affiliate thereof, and all franchise taxes, branch taxes, taxes on doing
business or taxes on the overall capital or net worth of any Lender or its
applicable lending office, or any branch or affiliate thereof, in each case
imposed in lieu of net income taxes, imposed: (i) by the jurisdiction under
the laws of which such Lender, applicable lending office, branch or affiliate
is organized or is located, or in which its principal executive office is
located, or any nation within which such jurisdiction is located or any
political subdivision thereof; or (ii) by reason of any connection between the
jurisdiction imposing such tax and such Lender, applicable lending office,
branch or affiliate other than a connection arising solely from such Lender
having executed, delivered or performed its obligations, or received
payment under or enforced, this Credit Agreement or any Notes.  If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any
amounts payable to an Agent or any Lender hereunder or under any Notes, (A)
the amounts so payable to such Agent or such Lender shall be increased to the
extent necessary to yield to such Agent or such Lender (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at
the rates or in the amounts specified in this Credit Agreement and any Notes,
provided, however, that the Credit Parties shall be entitled to deduct and
withhold any Non-Excluded Taxes and shall not be required to increase
any such amounts payable to any Lender that is not organized under the laws of
the United States of America or a state thereof if such Lender fails to comply
with the requirements of paragraph (b) of this subsection whenever any
Non-Excluded Taxes are payable by the Credit Parties, and (B) as promptly as
possible thereafter the Credit Parties shall send to such Agent for its own
account or for the account of such Lender, as the case may be, a certified
copy of an original official receipt received by the Credit Parties showing
payment thereof.  If the Credit Parties fail to pay any Non-Excluded Taxes
when due to the appropriate taxing authority or fails to remit to such Agent
the required receipts or other required documentary evidence, the Credit
Parties shall indemnify such Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by such Agent or any Lender as a
result of any such failure.  Each Lender agrees that it will promptly refund
any amounts received by it pursuant to this Section 4.9 that were  erroneously
billed to the Credit Parties, together with interest thereon at the Base Rate. 
The agreements in this subsection shall survive the termination of this Credit
Agreement and the payment of the Loans and all other amounts payable
hereunder.

     (b)   Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

           (X)(i)on or before the date of any payment by Airgas under this
Credit Agreement or Notes to such Lender, deliver to Airgas and the U.S. Agent
(A) two (2) duly completed copies of United States Internal Revenue Service
Form 1001 or 4224, or successor applicable form, as the case may be,
certifying that it is entitled to receive payments under this Credit Agreement
and any Notes without deduction or withholding of any United States federal
income taxes and (B) an Internal Revenue Service Form W-8 or W-9, or successor


<PAGE> EX-58

applicable form, as the case may be, certifying that it is entitled to an
exemption from United States backup withholding tax;

             (ii)     deliver to Airgas and the U.S. Agent two (2) further
copies of any such form or certification on or before the date that any such
form or certification expires or becomes obsolete and after the occurrence of
any event requiring a change in the most recent form previously delivered by
it to Airgas; and

            (iii)     obtain such extensions of time for filing and complete
such forms or certifications as may reasonably be requested by Airgas or the
U.S. Agent; or

           (Y)   in the case of any such Lender that is not a "bank" within
the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (i)
represent to Airgas (for the benefit of Airgas and the U.S. Agent) that it is
not a bank within the meaning of Section 881(c)(3)(A) of the Internal Revenue
Code, (ii) agree to furnish to Airgas on or before the date of any payment by
Airgas, with a copy to the U.S. Agent two (2) accurate and complete original
signed copies of Internal Revenue Service Form W-8, or successor    applicable
form certifying to such Lender's legal entitlement at the date of such
certificate to an exemption from U.S. withholding tax under the provisions of
Section 881(c) of the Internal Revenue Code with respect to payments to be
made under this Credit Agreement and any Notes (and to deliver to Airgas and
the U.S. Agent two (2) further copies of such form on or before the date it
expires or becomes obsolete and after the occurrence of any event requiring a
change in the most recently provided form and, if necessary, obtain any
extensions of time reasonably requested by Airgas or the U.S. Agent for filing
and completing such forms), and (iii) agree, to the extent legally entitled to
do so, upon reasonable request by Airgas, to provide to Airgas (for the
benefit of Airgas and the U.S. Agent) such other forms as may be reasonably
required in order to establish the legal entitlement of such Lender to an
exemption from withholding with respect to payments under this Credit
Agreement and any Notes; unless in any such case any change in treaty, law or
regulation has occurred after the date such Person becomes a Lender hereunder
which renders all such forms inapplicable or which would prevent such Lender
from duly completing and delivering any such form with respect to it and
such Lender so advises Airgas and the U.S. Agent.  Each Person that shall
become a Lender or a participant of a Lender pursuant to subsection 11.3
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms, certifications and statements required pursuant to this
subsection, provided that in the case of a participant of a Lender the
obligations of such participant of a Lender pursuant to this subsection (b)
shall be determined as if the participant of a Lender were a Lender except
that such participant of a Lender shall furnish all such required forms,
certifications and statements to the Lender from which the related
participation shall have been purchased.

     4.11  Indemnity.

     Airgas promises to indemnify each U.S. Lender and to hold each U.S.
Lender harmless from any loss or expense which such U.S. Lender may sustain or
incur (other than through such U.S. Lender's breach of its obligations
hereunder, gross negligence or willful misconduct) as a consequence of (a)
default by Airgas in making a borrowing of, conversion into or continuation
of Eurodollar Loans or Quoted Rate U.S. Swingline Loans after Airgas has given
a notice requesting the same in accordance with the provisions of this Credit
Agreement, (b) default by Airgas in making any prepayment of a Eurodollar Loan
or a Quoted Rate U.S. Swingline Loan after Airgas has given a notice thereof
in accordance with the provisions of this Credit Agreement or (c) the making
of a prepayment of Eurodollar Loans or Quoted Rate U.S. Swingline Loans

<PAGE> EX-59

on a day which is not the last day of an Interest Period with respect thereto. 
With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (i) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to
borrow, convert or continue to the last day of the applicable Interest Period
(or, in the case of a failure to borrow, convert or continue, the Interest
Period that would have commenced on the date of such failure) in each case at
the applicable rate of interest for such Eurodollar Loans provided for herein
(excluding, however, the Applicable Percentage included therein, if any) over
(ii) the amount of interest (as reasonably determined by such U.S. Lender)
which would have accrued to such U.S. Lender on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
Eurodollar market.  The covenants of Airgas set forth in this Section 4.11
shall survive the termination of this Credit Agreement and the payment of
the Loans and all other amounts payable hereunder.

     4.12  Pro Rata Treatment.

     Except to the extent otherwise provided herein:

           (a)   Loans. 

           (i)   U.S. Dollar Loans.  Each Revolving U.S. Loan or 364-Day
Revolving Loan, each payment or prepayment of principal in respect of any
Revolving U.S. Loan or 364-Day Revolving Loan or reimbursement obligations
arising from drawings under U.S. Letters of Credit or from Participation
Interests in U.S. Swingline Loans, each payment of interest on the Revolving
U.S. Loans or 364-Day Revolving Loans or reimbursement obligations arising
from drawings under U.S. Letters of Credit, each payment of the Unused
Revolving U.S Commitment Fee or the Unused 364-Day Revolving Commitment Fees,
each payment of the Standby U.S. Letter of Credit Fee, each payment of the
Trade U.S. Letter of Credit Fee, each reduction of the Revolving U.S.
Committed Amount or the 364-Day Revolving Committed Amount and each  
conversion or extension of any Revolving U.S. Loan or 364-Day Revolving Loan,
shall be allocated pro rata among the U.S. Lenders in accordance with the
respective principal amounts of their outstanding Revolving U.S. Loans and
Participation Interests in Revolving U.S. Loans, U.S. Letters of Credit and
U.S. Swingline Loans or their outstanding 364-Day Revolving Loans and
Participation Interests in 364-Day Revolving Loans, as applicable.  With
respect to Competitive U.S. Loans, if Airgas fails to specify the particular
Competitive U.S. Loan or Loans as to which any payment or other amount should
be applied and it is not otherwise clear as to the particular Competitive U.S.
Loan or Loans to which such payment or other amounts relate, or any such
payment or other amount is to be applied to Competitive U.S. Loans without
regard to any such direction by Airgas, then each payment or prepayment of
principal on Competitive U.S. Loans and each payment of interest or other
amount on or in respect of Competitive U.S. Loans, shall be allocated pro rata
among the relevant U.S. Lenders in accordance with the then outstanding
amounts of their respective Competitive U.S. Loans.

           (ii)  Canadian Dollar Loans.  Each Revolving Canadian Loan, each
creation of a Bankers' Acceptance, each payment or prepayment of principal in
respect of any Revolving Canadian Loan, BA Outstandings or reimbursement
obligations arising from drawings under Canadian Letters of Credit, each
payment of interest on the Revolving Canadian Loans or on reimbursement
obligations arising from drawings under Canadian Letters of Credit, each
payment of the Acceptance Fee on Bankers' Acceptances, each payment of the
Unused Revolving Canadian Commitment Fee, each payment of the Standby Canadian
Letter of Credit Fee, each payment of the Trade Canadian Letter of Credit Fee,
each reduction of the Revolving Canadian Committed Amount and each conversion 

<PAGE> EX-60

or extension of any Revolving Canadian Loan, shall be allocated pro rata
among the Canadian Lenders in accordance with the respective principal amounts
of their outstanding Revolving Canadian Loans, BA Outstandings and
Participation Interests in Revolving Canadian Loans, Canadian Letters of
Credit and BA Outstandings.

     (b)   Advances.  Unless the U.S. Agent or the Canadian Agent, as
appropriate, shall have been notified in writing by any Lender prior to any
extension of credit that such Lender will not make the amount that would
constitute its ratable share of such extension of credit available
to such Agent, such Agent may assume that such Lender is making such amount
available to such Agent, and such Agent may, in reliance upon such assumption,
make available to the relevant Credit Party(ies) a corresponding amount.  If
such amount is not made available to the applicable Agent by such Lender
within the time period specified therefor hereunder, such Lender shall pay
to such Agent, on demand, such amount with interest thereon at a rate equal
to, in the case of any extension of credit in U.S. Dollars, the Federal Funds
Rate, or, in the case of any extension of credit in Canadian Dollars, the
interbank rate (as defined in the Canadian Payment Association Rules), for the
period until such Lender makes such amount immediately available to such
Agent.  A certificate of the U.S. Agent or the Canadian Agent, as applicable,
submitted to any Lender with respect to any amounts owing under this
subsection shall be conclusive in the absence of manifest error.

     4.13  Sharing of Payments.

     The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan, LOC Obligations, BA Outstandings
or any other obligation owing to such Lender under this Credit Agreement
through the exercise of a right of setoff, banker's lien or counterclaim, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code (or similar provision of the Canadian bankruptcy laws) or other security
or interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Credit Agreement, such Lender shall promptly
purchase from the other Lenders a participation in such Loans, LOC
Obligations, BA Outstandings and other obligations in such amounts, and make
such other adjustments from time to time, as shall be equitable to the end
that all Lenders share such payment in accordance with their respective
ratable shares as provided for in this Credit Agreement.  The Lenders further
agree among themselves that if payment to a Lender obtained by such Lender
through the exercise of a right of setoff, banker's lien, counterclaim or
other event as aforesaid shall be rescinded or must otherwise be restored,
each Lender which shall have shared the benefit of such payment shall, by
repurchase of a participation theretofore sold, return its share of that
benefit (together with its share of any accrued interest payable with respect
thereto) to each Lender whose payment shall have been rescinded or otherwise
restored.  The Credit Parties agree that any Lender so purchasing such a
participation may, to the fullest extent permitted by law, exercise all rights
of payment, including setoff, banker's lien or counterclaim, with respect to
such participation as fully as if such Lender were a holder of such Loan, LOC
Obligations, BA Outstandings or other obligation in the amount of such
participation.  Except as otherwise expressly provided in this Credit
Agreement, if any Lender or an Agent shall fail to remit to an Agent or any
other Lender an amount payable by such Lender or such Agent to an Agent or
such other Lender pursuant to this Credit Agreement on the date when such
amount is due, such payments shall be made together with interest thereon for
each date from the date such amount is due until the date such amount is paid
to the Agent or such other Lender at a rate per annum equal to the Federal
Funds Rate.  If under any applicable bankruptcy, insolvency or other similar 

<PAGE> EX-61

law, any Lender receives a secured claim in lieu of a setoff to which this
Section 4.13 applies, such Lender shall, to the extent practicable, exercise
its rights in respect of such secured claim in a manner consistent with the
rights of the Lenders under this Section 4.13 to share in the benefits of any
recovery on such secured claim.

     4.14  Payments, Computations, Etc. 

     Except as otherwise specifically provided herein, (i) all payments in
respect of Revolving Canadian Loans, Canadian Swingline Loans, Canadian
Letters of Credit, Bankers' Acceptances, interest on Revolving Canadian Loans,
the Acceptance Fee on Bankers' Acceptances or the Unused Revolving Canadian
Commitment Fee shall be made to the Canadian Agent in Canadian Dollars in
immediately available funds, without offset, deduction, counterclaim or
withholding of any kind, at the Canadian Agent's office specified in Schedule
2.1(a) not later than 2:00 P.M. (Toronto, Ontario time) on the date when due
and (ii) all other payments hereunder (other than payments in respect of
Competitive U.S. Loans) shall be made to the U.S. Agent in dollars in
immediately available funds, without offset, deduction, counterclaim or
withholding of any kind, at the U.S. Agent's office specified in Schedule
2.1(a) not later than 2:00 P.M. (Charlotte, North Carolina time) on the date
when due.  Payments received after such times shall be deemed to have been
received on the next succeeding Business Day.  The relevant Agent may (but
shall not be obligated to) debit the amount of any such payment which is not
made by such time to any ordinary deposit account of the applicable Credit
Parties maintained with such Agent (with notice to such Credit Parties).  Each
Credit Party shall, at the time it makes any payment under this Credit
Agreement (other than payments in respect of Competitive U.S. Loans), specify
to the relevant Agent the Loans, LOC Obligations, BA Outstandings, Fees,
Acceptance Fees, interest or other amounts payable by the Credit Parties
hereunder to which such payment is to be applied (and in the event that it
fails so to specify, or if such application would be inconsistent with the
terms hereof, such Agent shall distribute such payment to the Lenders in such
manner as such Agent may determine to be appropriate in respect of obligations
owing by the Credit Parties hereunder, subject to the terms of Section
4.12(a)).  The U.S. Agent or the Canadian Agent, as applicable, will
distribute such payments to such Lenders, if any such payment is received
prior to 12:00 NOON (Charlotte, North Carolina time or Toronto, Ontario time,
as applicable) on a Business Day in like funds as received prior to the end of
such Business Day and otherwise such Agent will distribute such payment to
such Lenders on the next succeeding Business Day.  All payments of principal
and interest in respect of Competitive U.S. Loans shall be in accordance
with the terms of Section 2.2.  Whenever any payment hereunder shall be stated
to be due on a day which is not a Business Day, the due date thereof shall be
extended to the next succeeding Business Day (subject to accrual of interest
and Fees for the period of such extension), except that in the case of
Eurodollar Loans, if the extension would cause the payment to be made in the
next following calendar month, then such payment shall instead be made on the
next preceding Business Day.  Except as expressly provided otherwise herein,
all computations of interest and fees shall be made on the basis of actual
number of days elapsed over a year of 360 days, except with respect to
computation of interest on U.S. Base Rate Loans which (unless the U.S. Base
Rate is determined by reference to the Federal Funds Rate) shall be calculated
based on a year of 365 or 366 days, as appropriate.  Interest shall accrue
from and include the date of borrowing, but exclude the date of payment.

     (a)   The audited consolidated and consolidating balance sheet of the
Consolidated Parties, and the related consolidated and consolidating
statements of earnings and statements of cash flows, as of March 31, 1997 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 the Consolidated Parties as at the end of, and the related unaudited
interim statements of earnings and of cash flows for, each quarterly period

from March 31, 1997 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 Material 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 1998, 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, 1997, 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.

     Each Consolidated Party (a) is a corporation duly organized, validly
existing and is in good standing under the laws of the jurisdiction of its

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 


<PAGE> EX-65

Material Adverse Effect, and (d) is in compliance with all material
Requirements of Law.

     6.4   Power; Authorization; Enforceable Obligations.

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

to which it is a party) enforceable against such Credit Party in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditors' rights generally and by general equitable
principles (whether enforcement is sought by proceedings in equity or at law).

     6.5   No Legal Bar.

     The execution, delivery and performance of the Credit Documents by any
Credit Party, the borrowings hereunder and the use of the proceeds thereof (a)
will not violate any Requirement of Law or contractual obligation of such
Credit Party or any of its Subsidiaries in any respect that would reasonably
be expected to have a Material Adverse Effect, (b) will not result in, or
require, the creation or imposition of any Lien on any of the properties or
revenues of such Credit Party or any of its Subsidiaries pursuant to any such
Requirement of Law or contractual obligation, and (c) will not violate or
conflict with any provision of such Credit Party's articles of incorporation
or by-laws.

     6.6   No Material Litigation.

     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)

     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.

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

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

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

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

occurred with respect to a Plan which has subjected or may subject any
Consolidated Party or any ERISA Affiliate to any liability under Sections 406,
409, 502(i), or 502(l) of ERISA or Section 4975 of the Code, or under any
agreement or other instrument pursuant to which any Consolidated Party or any
ERISA Affiliate has agreed or is required to indemnify any person against any
such liability. 

     6.13  Governmental Regulations, Etc.

     (a)   No part of the proceeds of the Loans will be used, directly or
indirectly, for the purpose of purchasing or carrying any "margin stock"
within the meaning of Regulation G or Regulation U, or for the purpose of
purchasing or carrying or trading in any securities other than securities
issued by Airgas.  If requested by any Lender or the U.S. Agent, the Credit
Parties will furnish to the U.S. Agent and each Lender a statement to the
foregoing effect in conformity with the requirements of FR Form U-1 referred
to in said Regulation U.  No indebtedness being reduced or retired out of the
proceeds of the Loans was or will be incurred for the purpose of purchasing or
carrying any margin stock within the meaning of Regulation U or any "margin
security" within the meaning of Regulation T other than securities issued by
Airgas.  "Margin stock" within the meanings of Regulation U does not
constitute more than 25% of the value of the consolidated assets of the
Consolidated Parties.  None of the transactions contemplated by this
Credit Agreement (including, without limitation, the direct or indirect use of
the proceeds of the Loans) will violate or result in a violation of the
Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as

Investment Company Act of 1940, as amended, and is not controlled by such a 

<PAGE> EX-68

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.

     (d)   Each Consolidated Party has obtained all material licenses,
permits, franchises or other governmental authorizations necessary to the
ownership of its respective Property and to the conduct of its business.

     (e)   No Consolidated Party is in violation of any applicable statute,
regulation or ordinance of the United States of America or Canada, or of any
state, province, city, town, municipality, county or any other jurisdiction,
or of any agency thereof (including without limitation, environmental laws and
regulations), which violation could reasonably be expected to have a Material
Adverse Effect.

     (f)   Each Consolidated Party is current with all material reports and
documents, if any, required to be filed with any state or federal securities
commission or similar agency and is in full compliance in all material
respects with all applicable rules and regulations of such commissions.

to finance loans, advances and other investments by the Consolidated Parties
to the extent permitted under this Credit Agreement and (iv) for the working

connection with appeal bonds, reimbursement obligations arising in connection
with surety and reclamation bonds, reinsurance, domestic or international
trade transactions and obligations not otherwise aforementioned relating to
acquisitions by the Consolidated Parties and other transactions entered into
by the applicable account party in the ordinary course of business.

     6.16  Environmental Matters.

     Except as could not reasonably be expected to have a Material Adverse
Effect:

     (a)   Each of the facilities and properties owned, leased or operated by
any Consolidated Party (the "Properties") and all operations at the Properties
are in compliance with all applicable Environmental Laws, and there is no
violation of any Environmental Law with respect to the Properties or the
businesses operated by any Consolidated Party (the "Businesses"), and there
are no conditions relating to the Businesses or Properties that could give
rise to liability under any applicable Environmental Laws.

Materials of Environmental Concern at, on or under the Properties in amounts
or concentrations that constitute or constituted a violation of, or could give
rise to liability under, Environmental Laws.

     (c)   No Consolidated Party has received any written or verbal notice of,
or inquiry from any Governmental Authority regarding, any violation, alleged
violation, non-compliance, liability or potential liability regarding
environmental matters or compliance with Environmental Laws with regard to any

knowledge or reason to believe that any such notice will be received or is
being threatened.

disposed of from the Properties, or generated, treated, stored or disposed of
at, on or under any of the Properties or any other location, in each case by

would be reasonably likely to give rise to liability under, any applicable
Environmental Law.

     (e)   No judicial proceeding or governmental or administrative action is
pending or, to the best knowledge of Airgas, threatened, under any
Environmental Law to which any Consolidated Party is or will be named as a
party, nor are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial
requirements outstanding under any Environmental Law with respect to any
Consolidated Party, the Properties or the Businesses.

     (f)   There has been no release or, threat of release of Materials of
Environmental Concern at or from the Properties, or arising from or related to
the operations (including, without limitation, disposal) of any Consolidated
Party in connection with the Properties or otherwise in connection with the

           (b)   Representations.  Any representation, warranty or statement
made or deemed to be made by any Credit Party herein, in any of the other

be delivered pursuant hereto or thereto shall prove untrue in any material
respect on the date as of which it was deemed to have been made; or


           (c)   Covenants.  Any Credit Party shall default in the due
performance or observance by it of any term, covenant or agreement (other than
those referred to in subsections (a) or (b) of this Section 9.1) contained in

<PAGE> EX-77

any Consolidated Party, such occurrence is in connection with a bona fide
dispute as to the right of the applicable Person to offset such Indebtedness
against indemnification obligations of the holder of such Indebtedness to such
Person and such Person shall have made adequate provision (as determined by
the Required Lenders in their reasonable discretion) for such Indebtedness on

such holders) to cause (determined without regard to whether any notice or
lapse of time is required), any such Indebtedness to become due prior to its
stated maturity; or (B) any such Indebtedness shall be declared due and

waived, shall exist with respect to any Plan, or any lien shall arise on the
assets of any Consolidated Party or any ERISA Affiliate in favor of the PBGC

to result in the termination of such Plan forpurposes of Title IV of ERISA;

Multiple Employer Plan, which is, in the reasonable opinion of the U.S. Agent,
likely to result in (i) the termination of such Plan for purposes of Title IV

liability in connection with a withdrawal from, reorganization of (within the
meaning of Section 4241 of ERISA), or insolvency or (within the meaning of
Section 4245 of ERISA) such Plan; or (4) any prohibited transaction (within
the meaning of Section 406 of ERISA or Section 4975 of the Code) or breach of
fiduciary responsibility shall occur which may subject any Consolidated Party
or any ERISA Affiliate to any liability under Sections 406, 409, 502(i), or

instrument pursuant to which any Consolidated Party or any ERISA Affiliate has

acquisition of, control over, Voting Stock of any Credit Party(or other
securities convertible into such Voting Stock) representing 50% or more of the

Credit Party which gives such Person and/or its Affiliates an aggregate
ownership of more than 50% of the Voting Stock of such Credit Party;
provided further, if such Person and/or its Affiliates have filed a tender
offer statement with the Securities and Exchange Commission in
connection with such 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.

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(e), 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

and all Loans, all reimbursement obligations arising from drawings under
Letters of Credit, all accrued interest in respect thereof, all accrued and
unpaid Fees and other indebtedness or obligations owing to an Agent and/or any
of the Lenders hereunder automatically shall immediately become due and
payable without the giving of any notice or other action by the U.S. Agent or
the Lenders.

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,

or affiliates. 

     10.7  Indemnification.

     The Lenders agree to indemnify the U.S. Agent in its capacity as such (to

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. 

<PAGE> EX-82

Agent under or in connection with any of the foregoing; provided that no
Lender shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or willful
misconduct of the U.S. Agent.  If any indemnity furnished to the U.S. Agent
for any purpose shall, in the opinion of the U.S. Agent, be insufficient or
become impaired, the U.S. Agent may call for additional indemnity from
the Lenders and cease, or not commence, to do the acts indemnified against
until such additional indemnity is furnished.  The Canadian Lenders agree to
indemnify the Canadian Agent in its capacity as such (to the extent not
reimbursed by the Credit Parties and without limiting the obligation of the
Credit Parties to do so), ratably according to their respective Commitments
(or if the Commitments have expired or been terminated, in accordance with the
respective principal amounts of outstanding Loans and Participation Interests
of the Lenders), from and against any and all liabilities, obligations,

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 

<PAGE> EX-83

appropriate, then the retiring U.S. Agent or Canadian Agent, as applicable,
shall select a successor U.S. Agent or successor Canadian Agent, as
applicable, acceptable to Airgas, provided such successor is a Lender
hereunder or, in the case of a successor U.S. Agent, a commercial bank
organized under the laws of the United States of America or of any State

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

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,

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

     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,
under the Notes, the other Credit Documents or otherwise, irrespective of
whether such Lender shall have made any demand hereunder and although such
obligations, liabilities or claims, or any of them, may be contingent or
unmatured, and any such set-off shall be deemed to have been made immediately
upon the occurrence of an Event of Default even though such charge is made or
entered on the books of such Lender subsequent thereto.  Any Person purchasing




<PAGE> EX-85

a participation in the Loans and Commitments hereunder pursuant to Section
4.13 or Section 11.3(c) may exercise all rights of set-off with respect to its
participation interest as fully as if such Person were a Lender
hereunder.

     11.3  Benefit of Agreement.

     (a)   Generally.  This Credit Agreement shall be binding upon and inure
to the benefit of and be enforceable by the respective successors and assigns
of the parties hereto; provided that a Credit Party may not assign or transfer
any of its interests without prior written consent of all the Lenders;
provided further that the rights of each Lender to transfer, assign or grant
participations in its rights and/or obligations hereunder shall be limited as
set forth in this Section 11.3, provided however that nothing herein shall
prevent or prohibit any Lender from (i) pledging its Loans hereunder to a
Federal Reserve Bank in support of borrowings made by such Lender
from such Federal Reserve Bank, or (ii) granting assignments or selling
participations in such Lender's Loans and/or Commitments hereunder to its
parent company and/or to any Affiliate or Subsidiary of such Lender.

     (b)   Assignments.  Each Lender may assign all or a portion of its rights
and obligations hereunder, pursuant to an assignment agreement substantially
in the form of Schedule 11.3(b), to (i) any Lender, any Subsidiary of a Lender
or any Affiliate of a Lender under direct or indirect common control with such
Lender, or (ii) any other commercial bank, financial institution or 
"accredited investor" (as defined in Regulation D of the Securities and
Exchange Commission) reasonably acceptable to the U.S. Agent, Airgas and, in
the case of any assignment by a Canadian Lender, the Canadian Agent (provided
that it shall not be unreasonable for Airgas to withhold its approval for any
assignment to any competitor of Airgas (which term "competitor" shall not
include a Person solely by reason of the fact that such Person is making loans
to, accepting deposits from or otherwise generally engaging in banking
business with any competitor of Airgas); provided that (i)(A) in the case of
any assignment by a U.S. Lender of all or any portion of such U.S. Lender's
Revolving U.S. Commitment or 364-Day Revolving Commitment, (other than any
assignment to an existing Lender), such assignment shall be in a minimum
aggregate amount of U.S.$5,000,000 of such Commitments and in integral
multiples of U.S.$1,000,000 above such amount (or, if less, the remaining
amount of the Commitment being assigned by such U.S. Lender) or (B) in the
case of  any assignment by a Canadian Lender of all or any portion of such
Canadian Lender's Revolving Canadian Commitment (other than any assignment to
an existing Lender), such assignment shall be in a minimum aggregate amount of
C$1,500,000  of such Commitment and in integral multiples of C$100,000 above
such amount (or, if less, the remaining amount of the Commitment being
assigned by such Canadian Lender) and (ii) each such assignment shall be of a
constant, not varying, percentage of all such Lender's rights and obligations
under this Credit Agreement.  Any assignment of all or any portion of a U.S.
Lender's Revolving U.S. Commitment or 364-Day Revolving Commitment hereunder
shall be effective upon delivery to the U.S. Agent of written notice of the
assignment together with a transfer fee of U.S.$3,500 payable to the U.S.
Agent for its own account from and after the effective date specified in the
applicable assignment agreement. Any assignment of all or any portion of a
Canadian Lender's Revolving Canadian Commitment hereunder shall be effective
upon (i) delivery to the U.S. Agent and Canadian Agent of written notice of
the assignment and (ii) payment of a transfer fee of C$3,500 payable to the
Canadian Agent for its own account from and after the effective date specified
in the applicable assignment agreement.  In addition, the assigning Lender
will give prompt notice to Airgas of any such assignment.  Upon the
effectiveness of any such assignment (and after notice to, and (to the extent
required pursuant to the terms hereof), with the consent of, Airgas as
provided herein), the assignee shall become a "Lender" for all purposes of 

<PAGE> EX-86

this Credit Agreement and the other Credit Documents and, to the extent of
such assignment, the assigning Lender shall be relieved of its obligations
hereunder to the extent of the Loans and Commitment components being assigned. 
Along such lines each Credit Party agrees that upon notice of any such
assignment and surrender of the appropriate Note or Notes, it will promptly
provide to the assigning Lender and to the assignee separate promissory
notes in the amount of their respective interests substantially in the form of
the original Note (but with notation thereon that it is given in substitution
for and replacement of the original Note or any replacement notes thereof). 
By executing and delivering an assignment agreement in accordance with this
Section 11.3(b), the assigning Lender thereunder and the assignee thereunder
shall be deemed to confirm to and agree with each other and the other parties
hereto as follows: (i) such assigning Lender warrants that it is the legal and
beneficial owner of the interest being assigned thereby free and clear of any
adverse claim; (ii) except as set forth in clause (i) above, such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Credit Agreement, any of the other Credit Documents or
any other instrument or document furnished pursuant hereto or thereto, or the
execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Credit Agreement, any of the other Credit Documents or any other
instrument or document furnished pursuant hereto or thereto or the financial
condition of any Credit Party or any of its respective Affiliates or the
performance or observance by any Credit Party of any of its obligations under
this Credit Agreement, any of the other Credit Documents or any other
instrument or document furnished pursuant hereto or thereto; (iii) such
assignee represents and warrants that it is legally authorized to enter into
such assignment agreement; (iv) such assignee confirms that it has received a
copy of this Credit Agreement, the other Credit Documents and such other
documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into such assignment agreement; (v)
such assignee will independently and without reliance upon the Agents, such
assigning Lender or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Credit Agreement
and the other Credit Documents; (vi) such assignee appoints and authorizes the
Agents to take such action on its behalf and to exercise such powers under
this Credit Agreement or any other Credit Document as are delegated to the
Agents by the terms hereof or thereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all the obligations which by the terms
of this Credit Agreement and the other Credit Documents are required to be
performed by it as a Lender.

     (c)   Participations.  Each Lender may sell, transfer, grant or assign
participations in all or any part of such Lender's interests and obligations
hereunder; provided that (i) such selling Lender shall remain a "Lender" for
all purposes under this Credit Agreement (such selling Lender's obligations
under the Credit Documents remaining unchanged) and the participant shall
not constitute a Lender hereunder, (ii) no such participant shall have, or be
granted, rights to approve any amendment or waiver relating to this Credit
Agreement or the other Credit Documents except to the extent any such
amendment or waiver would (A) reduce the principal of or rate of interest on
or Fees in respect of any Loans in which the participant is participating,
(B) postpone the date fixed for any payment of principal (including extension
of the Termination Date or the date of any mandatory prepayment), interest or
Fees in which the participant is participating or (C) alter the obligations of
the Guarantor, and (iii) sub-participations by the participant (except to an
affiliate, parent company or affiliate of a parent company of the participant)
shall be prohibited.  In the case of any such participation, the participant
shall not have any rights under this Credit Agreement or the other Credit 

<PAGE> EX-87

Documents (the participant's rights against the selling Lender in respect of
such participation to be those set forth in the participation agreement with
such Lender creating such participation) and all amounts payable by the Credit
Parties hereunder shall be determined as if such Lender had not sold such
participation, provided, however, that such participant shall be entitled to
receive additional amounts under Sections 4.6, 4.9, 4.10 and 4.11 to the same
extent as if it were a Lender provided that it shall not be entitled to
receive any more than the selling Lender would have received had it not sold
the participation.

     11.4  No Waiver; Remedies Cumulative.

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

     11.5  Payment of Expenses, Etc.

     The Credit Parties agree to:  (i) pay all reasonable out-of-pocket costs
and expenses (A) of the U.S. Agent in connection with the negotiation,
preparation, execution and delivery and administration of this Credit
Agreement and the other Credit Documents and the documents and instruments
referred to therein (including, without limitation, the reasonable fees and
expenses of Moore & Van Allen, PLLC, special counsel to the Agents as well as
Canadian counsel to the Agents) and any amendment, waiver or consent relating
hereto and thereto including, but not limited to, any such amendments, waivers
or consents resulting from or related to any work-out, renegotiation or
restructure relating to the performance by the Credit Parties under this
Credit Agreement and (B) of the U.S. Agent and the Lenders in connection with
enforcement of the Credit Documents and the documents and instruments referred
to therein (including, without limitation, in connection with any such
enforcement, the reasonable fees and disbursements of counsel for the U.S.
Agent and each of the Lenders); (ii) pay and hold each of the Lenders
harmless from and against any and all present and future stamp and other
similar taxes with respect to the foregoing matters and save each of the
Lenders harmless from and against any and all liabilities with respect to or
resulting from any delay or omission (other than to the extent attributable to
such Lender) to pay such taxes; and (iii) indemnify each Agent, each Lender,
its officers, directors, employees, representatives and agents from and hold
each of them harmless against any and all losses, liabilities, claims, damages
or expenses incurred by any of them as a result of, or arising out of, or in
any way related to, or by reason of (A) any investigation, litigation or other
proceeding (whether or not any Agent or Lender is a party thereto) occurring
subsequent to and as the result of the occurrence of a Default or Event of
Default and related to the entering into and/or performance of any Credit
Document or the use of proceeds of any Loans (including other extensions of
credit) hereunder or the consummation of any other transactions contemplated
in any Credit Document, including, without limitation, the reasonable fees and
disbursements of counsel incurred in connection with any such investigation,
litigation or other proceeding or (B) the presence or Release of any Materials
of Environmental Concern at, under or from any Property owned, operated or 

<PAGE> EX-88

leased by any Consolidated Party, or the failure by any Consolidated Party to
comply with any Environmental Law (but excluding, in the case of either
of clause (A) or (B) above, any such losses, liabilities, claims, damages or
expenses to the extent incurred by reason of gross negligence or willful
misconduct on the part of the Person to be indemnified).

     11.6  Amendments, Waivers and Consents.

     Neither this Credit Agreement  nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is
in writing entered into by, or approved in writing by, the Required Lenders
and the Credit Parties, provided that no such amendment, change, waiver,
discharge or termination shall, without the consent of each Lender:

           (i)   extend the final maturity of any Loan or of any reimbursement
obligations arising from drawings under Letters of Credit, or any portion
thereof;

           (ii)  reduce the rate or extend the time of payment of interest
(other than as a result of waiving the applicability of any post-default
increase in interest rates) on any Loan or of any reimbursement obligations
arising from drawings under Letters of Credit or fees hereunder;

           (iii) reduce the principal amount on any Loan or of any
reimbursement obligations arising from drawings under Letters of Credit or the
amount of any accrued interest or Fees, or increase the Commitments of the
Lenders over the amount thereof in effect (it being understood and agreed that
a waiver of any Default or Event of Default or of a mandatory reduction in the
total commitments shall not constitute a change in the terms of any Commitment
of any Lender);

           (iv)  amend, modify or waive any provision of this Section 11.6 or
Section 4.6, 4.10, 4.11, 4.12, 4.13, 9.1(a), 11.2, 11.3, 11.5 or 11.9;

any of its rights and obligations under (or in respect of) the Credit
Documents to which it is a party or 

           (vi)  alter the obligations of the Guarantor.

No provision of Section 2 may be amended without the consent of the Required
U.S. Lenders (provided further that (a) no provision of Section 2.3 may be
amended without the consent of the U.S. Issuing Lender and (b) no provision of
Section 2.4 may be amended without the consent of the U.S. Swingline Lender).

No provision of Section 3 may be amended without the consent of the Required
Canadian Lenders (provided further (a) that no provision of Section 3.2 may be
amended without the consent of the Canadian Swingline Lender and (b) no
provision of Section 3.3 may be amended without the consent of the Canadian
Issuing Lender).

No provision of Section 10 may be amended without the consent of the Agents.

making proof of this Credit Agreement to produce or account for more than one
such counterpart.

     11.8  Headings.

     The headings of the sections and subsections hereof are provided for

     All indemnities set forth herein, including, without limitation, in
Section 2.3(i), 4.9, 4.11, 10.7 or 11.5 shall survive the execution and

     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 NORTH CAROLINA.  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 North Carolina in Mecklenburg County, or of the United
States for the Western District of North Carolina, 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 Airgas arising under
Section 3.5:

           (i)   (A)  Without limiting the generality of subsections (a) and
(b) of this Section 11.10, Airgas agrees that any controversy or claim with
respect to it arising out of or relating to this Credit Agreement or the other
Credit Documents may, at the option of the Canadian Agent and the Canadian 

<PAGE> EX-90

Lenders, be settled immediately by submitting the same to binding arbitration
in the City of Charlotte, North Carolina (or such other place as the parties
may agree) in accordance with the Commercial Arbitration Rules then obtaining
of the American Arbitration Association.  Upon the request and submission of
any controversy or claim for arbitration hereunder, the Canadian Agent shall
give Airgas not less than 45 days written notice of the request for
arbitration, the nature of the controversy or claim, and the time and place
set for arbitration.  Airgas agrees that such notice is reasonable to enable
it sufficient time to prepare and present its case before the arbitration
panel.  Judgment on the award rendered by the arbitration panel may be entered
in any court in which any action could have been brought or maintained
pursuant to subparagraph (ii) below, including without limitation any court of
the State of North Carolina or any Federal court sitting in the State of
North Carolina.  The expenses of arbitration shall be paid by Airgas.
           
           (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)   Airgas hereby specifically consents and submits to the
jurisdiction of the courts of the State of North Carolina and courts of the
United States located in the State of North Carolina for purposes of entry of
a judgment or arbitration award entered by the arbitration panel.
           
           (ii)  The guarantee of Airgas under Section 3.5 is an international
     transaction in which payment of Canadian Dollars in Toronto, Ontario,
Canada, is of the essence, and Canadian Dollars shall be the currency of
account in all events in respect of the guaranty obligations of Airgas under
Section 3.5.  The payment obligation of Airgas shall not be discharged by an
amount paid in another currency or in another place, whether pursuant to a
judgment or otherwise, to the extent that the amount so paid on prompt
conversion to dollars and transfer to Toronto, Ontario, Canada, under normal
banking procedures does not yield the amount of dollars in Toronto, Ontario,
Canada due hereunder.  In the event that any payment by Airgas, whether
pursuant to a judgment or otherwise, upon conversion and transfer does not
result in payment of such amount of dollars in Toronto, Ontario, Canada, the
Canadian Agent and the Canadian Lenders shall have a separate cause of action
against Airgas for the additional amount necessary to yield the amount due and
owing to the Canadian Agent and the Canadian Lenders.

     (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

     (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

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

                             December 5, 1997


To the Lenders party to the Credit
  Agreement referred to below, 
  NationsBank, N.A., as U.S. Agent thereunder
  Canadian Imperial Bank of Commerce,
   as Canadian Agent thereunder

Ladies and Gentlemen:

     We have acted as special counsel to the U.S. Agent, the Canadian Agent
and the Lenders party to that certain Credit Agreement of even date herewith
among Airgas, Inc. ("Airgas"), Airgas Canada Inc., Red-D-Arc Limited and
Airgas Ontario Inc. (each a "Canadian Borrower" and, together with Airgas, the
"Credit Parties"), the Lenders party thereto, NationsBank, N.A., as U.S.
Agent, and Canadian Imperial Bank of Commerce, as Canadian Agent thereunder
(the "Credit Agreement").  This opinion is delivered to you pursuant to
Section 5.1(e) of the Credit Agreement.  Terms defined in the Credit Agreement
are incorporated herein by reference.

     In connection with this opinion, we have examined the originals, or
certified, conformed or reproduction copies, of all records, agreements,
instruments and documents as we have deemed relevant or necessary as the basis
for the opinions hereinafter expressed.  In stating our opinion, we have
assumed the genuineness of all signatures on original or certified copies, the
authenticity of documents submitted to us as originals and the conformity to
original or certified copies of all copies submitted to us as certified or
reproduction copies.

     We have also assumed, for purposes of the opinions expressed herein, (i)
that the parties to the Credit Documents have the corporate power and
authority to enter into and perform the Credit Documents and that the Credit
Documents have been duly authorized, executed and delivered by each such party
and (ii) the delivery of the consideration for the Credit Documents.

     The opinions expressed herein are subject to the following further
assumptions,
limitations, qualifications and exceptions:  

     (a)   Certain rights, remedies and waivers contained in the Credit
Documents may be rendered ineffective, or may be limited, by applicable laws
or judicial decisions governing such provisions, but such laws and judicial
decisions do not, in our opinion, make the Credit Documents inadequate for the
practical realization of the benefits and security which the Credit Documents
purport to provide.

     (b)   We express no opinion as to perfection of any lien on or security
interest in (or the priority of any lien on or security interest in) any
collateral securing any of the obligations of the Credit Parties under the
Credit Documents.

     Based upon the foregoing, and subject to the limitations set forth
herein, we are of the opinion that the Credit Documents constitute the legal,
valid and binding obligation of each Credit Party, enforceable in accordance
with their respective terms except to the extent that enforcement may be 

<PAGE> EX-119

limited by applicable bankruptcy, fraudulent conveyance, insolvency,
reorganization or other similar laws affecting creditors' rights generally and
by equity principles (regardless of whether enforcement is sought in equity or
at law).  Without limiting the generality of the foregoing, we express no
opinion as to the applicability to the obligations of any Credit Party under
the Credit Documents of Section 548 of the Bankruptcy Code or North Carolina
General Statutes Section 39-15 relating to fraudulent transfers and
obligations.

     This opinion is limited to the federal law of the United States of
America and the law of the State of North Carolina in effect on the date
hereof.

     This opinion is rendered solely for your benefit in connection with the
transaction described above and may not be used or relied upon by any other
person and may not be disclosed, quoted, filed with a governmental agency or
otherwise referred to without our prior written consent except to your bank
examiners, auditors, and counsel and to prospective transferees of your
interests under the Credit Documents and their professional advisers, or as 
required by law or pursuant to legal process.


                                  Very truly yours,

Earnings per share amounts were determined using the treasury stock method. 
This method assumes the exercise of all dilutive outstanding options and
warrants and the use of the aggregate proceeds therefrom to acquire the
Company's outstanding common stock.  Net earnings were divided by the weighted
average number of shares outstanding adjusted for the assumed exercise of the
options and warrants outstanding and repurchase of common stock to calculate
per share amounts.
