                       3700 Crestwood Parkway, Suite 200
                          Duluth, Georgia 30136-5583

                                     
                                  May 7, 1997      



Dear Shareholders:
             
         A Special Meeting of Shareholders of Carbonic Industries Corporation
("CIC") will be held at the offices of Osburn, Henning and Company at 617 East
Colonial Drive, Orlando, Florida on May 28, 1997 at 1:00 p.m.      

         At the Special Meeting, you will be asked to consider and vote upon the
approval of an Agreement and Plan of Merger ("Merger Agreement") pursuant to
which CIC will be merged into a wholly-owned subsidiary of Airgas, Inc. (the
"Airgas Subsidiary"). If the merger (the "Merger") is consummated, each
outstanding share of CIC Class A common stock, no par value (the "Class A
Common") will be converted into and exchanged for the right to receive an amount
of Airgas common stock, par value $0.01 per share ("Airgas Common Stock"), equal
to $43 in value (valued as described below), $43 in cash or a combination
thereof, at the shareholder's election, subject to proration and certain other
limitations more fully described in the enclosed Prospectus and Proxy Statement
(including that shareholders who own more than 500 shares of Class A Common, or
who own 500 or fewer shares but received such shares after March 12, 1997 from
someone who owned more than 500 shares on March 12, 1997, may not elect to
receive cash for more than 45% of the value of their Class A Common). In
addition, if the Merger is consummated, each share of CIC Class B Common Stock,
no par value ("Class B Common"), will be converted into and exchanged for the
right to receive $205 in cash or an amount of Airgas Common Stock equal to $205
in value (valued as described below), with 55% of such consideration to be paid
in Airgas Common Stock and 45% to be paid in cash, but also subject to proration
and certain other limitations as more fully described in the enclosed Prospectus
and Proxy Statement.

         For purposes of calculating the number of shares of Airgas Common Stock
which you will receive if the Merger is consummated, a share of Airgas Common
Stock is valued at $_______. This works out to approximately __________ shares
of Airgas Common Stock for each share of Class A Common and __________ shares of
Airgas Common Stock for each share of Class B Common.

         Please also note that, unless you own 500 or fewer shares of Class A
Common (and did not receive those shares after March 12, 1997 directly or
indirectly from someone who owned more than 500 shares on March 12, 1997), 55%
of the consideration you will receive for your CIC Common Stock (all in shares
of Airgas Common Stock) will be held in escrow for up to two years from the time
the Merger closes to cover certain indemnification obligations and to support
the tax treatment of this transaction.

         If you wish to receive any cash for your shares of Class A Common, you
must follow the procedures set forth in the Form of Cash Election/Transmittal
Letter, enclosed with the Proxy Statement/Prospectus, and described under
"Important Notice."
<PAGE>
 
         You should also return the enclosed Continuity of Interest Certificate
prior to the closing of the Merger. The purpose of this Certificate is to
support the tax treatment of the Merger.

         Details of the Merger are set forth in the accompanying Proxy
Statement/Prospectus, which you should read carefully and which contains a more
complete discussion of these matters.

         Your Board of Directors has unanimously approved the Merger and
believes that the Merger is in the best interests of CIC and its shareholders
and therefore unanimously recommends a vote FOR the Merger. The Merger must be
approved by each of a majority of the outstanding shares of Class A Common and a
majority of the outstanding shares of Class B Common.

         All shareholders are cordially invited to attend the Special Meeting in
person. Whether or not you plan to attend the meeting, please complete, date,
sign and promptly return your proxy card in the enclosed envelope (which
requires no postage if mailed in the United States). If you attend the meeting,
you may vote in person if you wish, even though you have previously returned
your proxy. It is important that your shares be represented and voted at the
Special Meeting.

To the Shareholders:
    
         Notice is hereby given that a Special Meeting of Shareholders of
Carbonic Industries Corporation ("CIC") will be held on May 28, 1997 at 1:00
p.m., at the offices of Osburn, Henning and Company, 617 East Colonial Drive,
Orlando, Florida for the following purposes:
                                                                               
             To consider and vote upon an Agreement and Plan of Merger
             dated March 12, 1997 (the "Merger Agreement") pursuant to
             which (i) CIC would be merged (the "Merger") into a
             wholly-owned subsidiary of Airgas, Inc. ("Airgas"), a Delaware
             corporation; (ii) holders of shares of CIC Class A Common
             Stock, no par value (the "Class A Common") (other than holders
             who perfect dissenters' rights), would receive for each share
             of Class A Common outstanding, at each holder's election,
             subject to proration and other limitations set forth in the
             Merger Agreement, either (a) shares of Airgas Common Stock,
             par value $.01 per share (the "Airgas Common Stock"), or (b)
             cash for up to 45% of the value of their shares of Class A
             Common; and (iii) holders of shares of CIC Class B Common
             Stock, no par value (the "Class B Common") (other than holders

                        CARBONIC INDUSTRIES CORPORATION

                                PROXY STATEMENT
                                ---------------
             
         This Prospectus of Airgas, Inc. ("Airgas"), a Delaware corporation,
relates to up to 2,411,766 shares of Airgas Common Stock, par value $.01 per
share (the "Airgas Common Stock"), to be issued in connection with the proposed
merger (the "Merger") of Carbonic Industries Corporation ("CIC") into a newly
formed, wholly-owned subsidiary of Airgas (the "Airgas Subsidiary"), with Airgas
Subsidiary surviving the Merger, in accordance with the Agreement and Plan of
Merger dated as of March 12, 1997, by and among Airgas, Airgas Subsidiary and
CIC (the "Merger Agreement"). This Prospectus also serves as a proxy statement
of CIC in connection with the solicitation of proxies by its Board of Directors
for use at the Special Meeting of shareholders of CIC to be held on May 28, 1997
at 1:00 p.m. at the offices of Osburn, Henning and Company, 617 East Colonial
Drive, Orlando, Florida. This Proxy Statement/Prospectus, with accompanying form
of proxy, is first being mailed to the CIC shareholders on or about
May 7, 1997.      

         Upon consummation of the Merger, all outstanding shares of CIC Class A
Common Stock, no par value (the "Class A Common") will be converted into the
right to receive, at each holder's election, subject to proration and other
limitations described herein, shares of Airgas Common Stock or cash for up to
45% of the value of a holder's shares, provided that holders of 500 or fewer
shares of Class A Common will not be subject to the 45% limitation unless the
shares were transferred of record to such holder after March 12, 1997 by a
person or entity who owned of record on March 12, 1997 more than 500 shares of
Class A Common (such shares not subject to the 45% limitation are hereinafter
referred to as the "De Minimis Shares"), and all outstanding shares of CIC Class
B Common Stock, no par value (the "Class B Common"), will be converted into
shares of Airgas Common Stock for 55% of the value of the  Class B Common
and, subject to proration, into cash for 45% of the value of the Class B Common
(all such Airgas Common Stock and cash into which the Class A Common and the
Class B Common are converted into the right to receive, collectively, the
"Merger Consideration"). Except for the De Minimis Shares, the Merger
Consideration payable to a CIC shareholder will be reduced by 0.25% for fees and
expenses related to the Merger and the Lockup/Escrow Agreement (the
"Lockup/Escrow Fee"). See "Summary - Merger Consideration" and "The Merger -
Conversion of Shares and Fractional Shares."

         THE AIRGAS SECURITIES TO BE OFFERED IN CONNECTION WITH THE MERGER HAVE
NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION NOR
HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT
AND PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

         The information included herein with respect to Airgas and its
subsidiaries and affiliates was supplied by Airgas, and the information
concerning CIC and its affiliates included herein was supplied by CIC.

         Holders of CIC Common Stock should carefully consider the information
set forth under "Investment Considerations."

The Companies

        Airgas

        Airgas is the largest independent distributor of industrial, medical and
specialty gases and related equipment in North America. Airgas' distribution
business is conducted through over 600 locations throughout North America.
Principal products distributed include: nitrogen, oxygen, argon, helium,
acetylene, carbon dioxide, nitrous oxide, hydrogen and welding gases and a
variety of medical and specialty gases as well as a wide selection of name-brand
welding equipment, accessories and industrial protective equipment
("hardgoods"). In connection with its gas distribution business, Airgas rents
industrial gas cylinders and bulk storage tanks to its customers. Airgas also
distributes industrial safety equipment and other industrial equipment and
supplies through its Airgas Direct Industrial ("ADI") segment. Airgas also
manufactures and sells acetylene gas as part of its distribution business. In
addition to its distribution business, Airgas operates four manufacturing
businesses which produce carbon products, calcium carbide, nitrous oxide and
carbon dioxide.

        Airgas' principal business strategies include continued profitable
growth through an active acquisition program, selective expansion of its product
lines and providing high value-added products and services at the lowest
possible cost to its customers.

        Airgas intends to broaden its product line by taking advantage of its
broad distribution network, and through additional acquisitions by its ADI
division. In addition, product line additions have included returnable
containers, specialty gases and additional hardgoods (such as industrial safety
products, fire protection products and industrial coatings). Airgas believes the
selective addition of complementary product offerings will enable it to better
serve its diverse, expanding customer base.

        CIC

        CIC is engaged in the production and distribution of liquid carbon
dioxide and solid carbon dioxide (dry ice) and the rental of carbon dioxide
equipment. CIC acquires carbon dioxide from natural sources and as a byproduct
of various manufacturing processes, and then


- --------------------------------------------------------------------------------

                                       4
<PAGE>
 
refines and processes it for distribution in bulk quantities in 19 states,
principally located east of the Mississippi River. CIC rents storage tanks and
related applications equipment to its carbon dioxide customers as an ancillary
service to its carbon dioxide supply business. On a volume basis, CIC believes
it is one of the four largest suppliers in the United States of carbon dioxide
in its various forms.

The Meeting
            
        A Special Meeting of holders of CIC Common Stock will be held on May 28,
1997 at 1:00 p.m. at the offices of Osburn, Henning and Company, 617 East
Colonial Drive, Orlando, Florida.      
            
        CIC has fixed the close of business on MAY 6, 1997 as the record date
for determining shareholders entitled to notice of and to vote at the meeting.
     
        See "Voting and Proxies."

Purposes of the Meeting

        The purpose of the CIC Special Meeting is to consider and vote upon a
proposal to approve the Merger Agreement and the Merger pursuant to which CIC
will be merged into the Airgas Subsidiary, with the Airgas Subsidiary surviving
the Merger.

Vote Required

        The affirmative vote of the holders of a majority of the outstanding
shares of Class A Common and the affirmative vote of the holders of a majority
of the outstanding shares of Class B Common is required to approve the Merger
Agreement and the Merger. Each share of Class A Common and Class B Common
entitles the holder to one vote. The directors and executive officers of CIC,
who hold approximately 18% of the outstanding Class A Common and approximately
80% of the outstanding Class B Common, have advised CIC that they presently
intend to vote their shares in favor of the Merger Agreement and the Merger,
although they are not required to do so.

        See "The Special Meeting - Proxies and Votes Required."

Recommendation and Reasons

        The Board of Directors of CIC unanimously recommends a vote FOR the
adoption and approval of the Merger Agreement and the Merger.


                                       5
<PAGE>
 
        The Board of Directors of CIC believes that the Merger is in the best
interests of the shareholders of CIC. The CIC Board of Directors believes that
the Merger will provide CIC with the capital and other resources necessary to
exploit expansion opportunities and grow its business, and that the Merger
Consideration can represent a potentially valuable return for the shareholders'
investment in CIC Common Stock. In addition, the exchange of CIC Common Stock
for Airgas Common Stock or cash will benefit CIC's shareholders by providing
them with liquidity after the expiration of the Lockup/Escrow Agreement with
respect to the escrowed shares because Airgas Common Stock is publicly traded.
See "Background and Related Matters -- CIC's Reasons for the Merger."

The Merger - General
    
        When the Merger becomes effective, CIC will be merged with and into the
Airgas Subsidiary, with the Airgas Subsidiary surviving the Merger. In the 
Merger, CIC shareholders (other than shareholders who perfect dissenters'
rights) will receive, at each holder's election, subject to proration and other
limitations, either the Stock Consideration (as defined herein) or the Cash
Consideration (as defined herein) for each share of CIC Common Stock
outstanding. In addition, outstanding CIC options will be assumed by Airgas and
become exercisable for shares of Airgas Common Stock in accordance with the
Class A Exchange Ratio (as defined herein).     

Merger Consideration

        The following Merger Consideration will be payable to the CIC
shareholders after the payment of the Lockup/Escrow Fee (which will not apply to
the De Minimis Shares):
            
        Class A Common. Each share of Class A Common will be converted into the
        --------------   
right to receive, at each holder's election but subject to proration and other
limitations, either (i) $43 in shares of Airgas Common Stock (the "Class A Stock
Consideration") or (ii) $43 in cash (the "Class A Cash Consideration") (with the
limitation that cash may be elected only for up to 45% of the value of the
holder's shares, except that the 45% limitation will not apply to the De Minimis
Shares). The Class A Stock Consideration will be equal to that number of shares
of Airgas Common Stock equal to the quotient of (a) $43.00 divided by (b)
$_______("the Average Airgas Price"). The foregoing quotient, which is ________,
is defined as the "Class A Exchange Ratio." The Average Airgas Price was
determined in accordance with the Merger Agreement by averaging the closing
sales price of the Airgas Common Stock for the five consecutive trading days
beginning on and including April 24, 1997.      

        The right of the holders of Class A Common to elect to receive cash for
up to 45% of the value of their shares of Class A Common will be subject to
proration and other limitations

described more fully in this Proxy Statement/Prospectus and in the Merger
Agreement, which provide generally that the total amount of the Merger
Consideration paid in cash (assuming that any dissenters are being paid fully 
in cash) (the "Aggregate Cash Consideration") cannot exceed the total amount of
the Merger Consideration paid in shares of Airgas Common Stock (the "Aggregate
Stock Consideration"), although a holder's percentage of Merger Consideration
being paid as Class A Cash Consideration will not be reduced more than two
percentage points.

        Class B Common. Each share of Class B Common will be converted into $205
        --------------
in shares of Airgas Common Stock (the "Class B Stock Consideration") or $205 in
cash (the "Class B Cash Consideration"). The Class B Stock Consideration will be
equal to that number of shares of Airgas Common Stock equal to the quotient of
(a) $205.00 divided by (b) $_________, the Average Airgas Price. The
foregoing quotient, which is ____________, is defined as the "Class B Exchange
Ratio." Each holder of shares of Class B Common will receive the Class B Stock
Consideration for 55% of the value of such holder's shares of Class B Common
subject to proration, but not above 57%. Each holder of shares of Class B Common
will receive (subject to proration, but not below 43%), the Class B Cash
Consideration for 45% of the value of such holder's shares of Class B Common.

        The Class A Stock Consideration and the Class B Stock Consideration are
sometimes collectively referred to herein as the "Stock Consideration" and the
Class A Cash Consideration and the Class B Cash Consideration are sometimes
collectively referred to herein as the "Cash Consideration."
            
        Fluctuations in Merger Consideration. On May __, 1997, the most recent
        ------------------------------------
practicable date prior to the date of this Proxy Statement/Prospectus, the
closing sale price of the Airgas Common Stock on the New York Stock Exchange,
Inc. (the "NYSE") was $____ per share. The market price of the Airgas Common
Stock will depend on, and is expected to fluctuate with, among other things, the
performance of Airgas, conditions (economic or otherwise) affecting the
industrial gas and equipment distribution industries, interest rates, market
conditions and other factors that generally influence the prices of securities.
See "Investment Considerations - Fluctuations In Market Price of Airgas Common 
Stock."      

Election Procedures
    
        The Merger Agreement provides that each holder of Class A Common has the
right, subject to the proration and other limitations described herein, to
submit a request specifying the number of shares of Class A Common owned by such
holder which such holder desires to have converted into either (i) shares of
Airgas Common Stock or (ii) cash. All elections must be made on the Form of Cash
Election/Transmittal Letter (the "Form of Cash Election"), a copy of which is
being mailed with this Proxy Statement/Prospectus, and must be received and
accepted by the Cash Election Deadline, which is May 28, 1997. The purpose of
the election procedure is to permit holders of Class A Common to express their
preferences for the type of consideration they wish to receive in the Merger,
provided that, except for the De Minimis Shares, a holder's Class A Cash
Consideration cannot exceed 45% of the value of each holder's shares of Class A
Common, and the Aggregate Cash Consideration cannot exceed the Aggregate Stock
Consideration (i.e., more     

                                       7
<PAGE>
 
than 50% of the Merger Consideration). Failure of a holder of shares of Class A
Common to complete properly and to return the Form of Cash Election to the
Exchange Agent (as defined herein) by the Cash Election Deadline, or failure to
comply with the election procedures described in this Proxy Statement/Prospectus
and Form of Cash Election, will cause all of such holder's shares of Class A
Common to be converted into the Class A Stock Consideration without regard to
the preference of such holder. Forms of Cash Election will be irrevocable upon
receipt by the Exchange Agent, unless amendment or withdrawal is permitted in
its sole and absolute discretion.

Shareholder Approval

        Assuming receipt of the approval of the Merger by CIC's shareholders,
the Merger will be consummated promptly upon the satisfaction or waiver of the
conditions of the Merger.

Conditions to the Merger; Termination and Amendment

        There are various conditions to the respective obligations of Airgas and
CIC to consummate the Merger, including approval of the Merger by the
shareholders of CIC and that assertion of dissenters' rights does not exceed 10%
of the issued and outstanding shares of Class A Common. Except with respect to
shareholder approval and other matters required by law, each of the parties to
the Merger Agreement may, at its option, waive compliance with any condition to
its obligation to consummate the Merger. See "The Merger -- Conditions Precedent
to the Consummation of the Merger; Waiver."

        The Merger Agreement may be terminated at any time prior to consummation
of the Merger by mutual consent of the Boards of Directors of Airgas and CIC. In
addition, the Merger Agreement may be terminated by either Airgas or CIC under
certain conditions, including if the Merger is not consummated by August 31,
1997. Certain amendments to the Merger Agreement may be made by the mutual
consent of Airgas and CIC at any time prior to the consummation of the Merger.
See "The Merger -- Termination and Amendment."

Interests of Certain Persons in the Merger

        A condition to the consummation of the Merger is that certain officers
of CIC enter into employment agreements with Airgas which include noncompete
provisions. Additionally, all outstanding options to purchase CIC Common Stock
will vest upon consummation of the Merger. The President of CIC and/or companies
owned by his sons will have an option to purchase CIC's dry ice operations in
Miami and Jacksonville, Florida.

        On December 1, 1996, Airgas acquired the pipeline that supplies natural
carbon dioxide to CIC's natural source facility in Star, Mississippi. This
source of carbon dioxide gas is one of two major sources of supply for CIC. In
July 1996 (before the acquisition by Airgas was completed), CIC amended its
supply contract to increase the supply of carbon dioxide it receives from the
pipeline. Under the contract, CIC has the right to purchase natural carbon
dioxide at prices set forth in the contract, based in part on the volume of
carbon dioxide purchased, until July 1, 2016. See "The Merger - Interests of
Certain Persons in the Merger."

Lockup/Escrow Agreement

        The Merger Agreement provides that 55% (subject to adjustment up to 57%
in the event of the proration of the Cash Consideration) of each CIC
shareholder's Merger Consideration (other than with respect to the De Minimis
Shares) issuable to the shareholders after the payment of the Lockup/Escrow Fee
will be paid in shares of Airgas Common Stock and held pursuant to the
Lockup/Escrow Agreement. Such shares may be used to satisfy indemnification
claims of up to $5,000,000 (after giving effect to a $500,000 deductible) made
within one year of the Closing Date arising as a result of a breach of the
representations, warranties and covenants made in the Merger Agreement or
related documents (except that certain claims, including those for broker fees
or those based on fraud, are not subject to the deductible or the limitation),
for any decrease in tax benefits to the Airgas Subsidiary resulting from an
adjustment with respect to tax returns filed by CIC on or prior to the Closing
Date and for certain other matters specified in the Merger Agreement. Even if no
such claims are made, the Airgas Common Stock will be held pursuant to the
Lockup/Escrow Agreement for a period of up to two years, to help support the
favorable tax treatment described herein. See "The Merger - Lockup/Escrow
Agreement."

Effective Time of the Merger

        The Merger will become effective on the date that the Certificate of
Merger is filed with the Secretary of the State of Delaware, provided that
Articles of Merger are filed with the Florida Department of State in accordance
with Florida law. These filings are expected to occur on the date of the Closing
of the Merger.

Federal Income Tax Consequences

        Consummation of the Merger is conditioned upon the receipt of an opinion
of counsel to Airgas stating that the Merger will be a tax-free reorganization
for federal income tax purposes and that no gain or loss will be recognized by
the shareholders of CIC on the exchange of their shares of CIC Common Stock for
shares of Airgas Common Stock (other than with respect to cash received by those
CIC shareholders receiving Cash Consideration and pursuant to dissenters'
rights). The tax opinion to be received is subject to various assumptions and
qualifications and is not binding on the Internal Revenue Service.


                                               9
<PAGE>
 
        In general, if pursuant to the Merger (i) a holder exchanges all of the
shares of CIC Common Stock owned by it solely for shares of Airgas Common Stock,
it will not recognize any gain or loss, and (ii) a holder exchanges all of the
shares of CIC Common Stock owned by it for a combination of shares of Airgas
Common Stock and cash, it will recognize gain equal to the lesser of (A) the
amount of cash received and (B) the difference between (1) the sum of the cash
received and the fair market value of the Airgas Common Stock received and (2)
its adjusted tax basis in the shares of CIC Common Stock surrendered. CIC
shareholders who receive cash pursuant to dissenters' rights will recognize gain
or loss, if any, for federal tax purposes. CIC SHAREHOLDERS SHOULD CONSULT WITH
THEIR OWN TAX ADVISERS REGARDING THE TAX CONSEQUENCES OF THE MERGER WITH RESPECT
TO THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY OF VARIOUS
STATE AND LOCAL TAX LAWS. See "The Proposed Merger -- Certain Federal Income Tax
Consequences of the Merger," "The Merger -- Dissenters' Rights" and "The Merger
- -- Election Procedures."

Accounting Treatment

        The Merger will be accounted for under the purchase method of accounting
in accordance with generally accepted accounting principles, whereby the
purchase price will be allocated based on the fair value of the assets acquired
and the liabilities assumed. See "The Merger -- Accounting Treatment."

Dissenters' Rights

        Each holder of CIC Common Stock who dissents from the Merger is entitled
to the rights and remedies of dissenting shareholders provided in the applicable
Florida statutes, subject to compliance with the procedures set forth therein. A
copy of such statutory provisions, as in effect on the date of this Proxy
Statement/Prospectus, is attached to this Proxy Statement/Prospectus as Appendix
B, and a summary thereof is set forth under "The Merger-Dissenters' Rights."

Listing

        The shares of Airgas Common Stock to be issued in the Merger will be
authorized for listing and trading on the NYSE.

Stock Prices and Dividends

        Airgas. On October 28, 1996, the last trading day before the proposed
        ------
Merger was first announced, the closing sale price of Airgas Common Stock on the
NYSE, as reported by the NYSE Composite Tape, was $22.375 per share. Airgas has
not paid any cash dividends on its Common Stock since inception and no cash
dividends are anticipated in the foreseeable future.

        CIC.  CIC is a private company, and, accordingly, no established public 
        --- 
trading market exists for the CIC Common Stock. CIC has generally paid an annual
dividend of varying amounts.

        See "Market Price of Common Stock" and "Dividend Policy."

Comparative per Share Data
            
        The following financial information reflects comparative per share
information relating to unaudited net earnings per share, book value per share
and cash dividends declared for (i) Airgas and CIC on a historical basis, (ii)
on a pro forma basis assuming the Merger had been effected for the periods
indicated and (iii) on a pro forma basis equivalent to one share of CIC Common
Stock. The information shown below should be read in conjunction with the
historical consolidated financial statements of Airgas and CIC including the
respective notes thereto, and the unaudited pro forma combined condensed
financial statements, including the notes thereto, appearing elsewhere in this
Proxy Statement/Prospectus. See "UNAUDITED PRO FORMA COMBINED CONDENSED
FINANCIAL STATEMENTS" and "INDEX TO FINANCIAL STATEMENTS." The pro forma
equivalent per share value of CIC Common Stock on any date has been prepared
assuming that the Average Airgas Price is equal to $15.00, that the Class A
Exchange Ratio for the Class A Common is 2.87 and the Class B Exchange Ratio for
the Class B Common is 13.67. The pro forma equivalent per share value of CIC
Common Stock on any date equals $15.00, multiplied by 2.87 for the Class A
Common and 13.67 for the Class B Common.

         value of the Class B Common was converted into Airgas Common Stock,
         respectively, and (iii) the Average Airgas Price was $15.00, the Class

         value per share of Class B Common excludes an assumed $92.25 Cash
         Consideration per share based on a 55% conversion into Airgas Common
         Stock.

The comparative pro forma per share data above assumes that 60% of the value of

               statements).

         On October 28, 1996, the last trading day prior to the public
announcement of the proposed Merger, the closing sale price of the Airgas Common
Stock on the NYSE was $22.375. On April 16, 1997, there were approximately
12,000 holders of record of the Airgas Common Stock, and the closing sale price
was $15.125.

         CIC is privately held and there is no established market for the CIC
Common Stock. CIC's management believes that the Class A Common has generally
been purchased and sold at book value, which was approximately $17.52 at
December 31, 1996. To CIC's management's knowledge, there have been no
transactions in Class B Common, except two recent charitable gifts of 2,500
shares each by Mr. W. Herbert Hinely and Mr. J. Vernon Hinely.
             
         As of April 16, 1997, there were approximately 262 holders of Class A
Common and four holders of Class B Common.

                                DIVIDEND POLICY

Airgas

         Airgas has never paid cash dividends. The present policy of Airgas is
to retain earnings to provide funds for the operation and expansion of its
business and not to pay cash dividends on its Common Stock. Any payment of
future dividends and the amounts thereof will depend upon Airgas' earnings,
financial condition, loan covenants, capital requirements and other factors
deemed relevant by the Board of Directors (see note 8 to Airgas' Consolidated
Financial Statements).

CIC

         The following dividends have been declared and paid on CIC Common
Stock:

                           INVESTMENT CONSIDERATIONS


Integration of Operations

         The benefits anticipated from the acquisition of CIC will not be
achieved fully unless its operations are successfully integrated into those of
Airgas. Furthermore, Airgas' acquisition strategy could place significant
demands on its management and financial resources. CIC shareholders should
consider the potential adverse impact that could result from Airgas' failure to
effectively integrate CIC and other companies acquired into the operations of
Airgas.

Continued Ability to Grow

         Airgas' significant growth in recent years has resulted in large part
from its many acquisitions of independent gas distributors, and its ability to
sustain such a rate of growth in the future will depend principally on
management's continued ability to identify prospective companies for acquisition
and management's further ability to negotiate favorable acquisition terms. Such
efforts will be affected by factors, many of which are outside of Airgas'
control, such as competition among buyers for such distributors and the ability
of Airgas to obtain financing for such acquisitions on favorable terms. In
making their decision, CIC shareholders are urged to consider that there can be
no assurance as to the

                                       14
<PAGE>
 
continued availability of prospective acquisition candidates or of Airgas'
ability to complete such transactions on favorable terms.

Dependence on Key Personnel

         Airgas' success in recent years (including its growth strategy) is
largely attributable to the efforts of certain key personnel and in particular
its Chairman and Chief Executive Officer, Peter McCausland. There can be no
assurance of such personnel's continued association with Airgas. Departure of
any such officers (and, in particular, Mr. McCausland) would likely have a
material adverse impact on the operations of Airgas and the price of the Airgas
Common Stock.

Interests of Certain Persons in the Merger

         Certain officers and directors of CIC will receive certain benefits as
a result of the Merger in addition to those which will result from the receipt
of the Merger Consideration in exchange for CIC Common Stock and the assumption
by Airgas of such persons' options to purchase CIC Common Stock. It is
anticipated that certain officers and other employees of CIC will enter into
employment agreements with Airgas or Airgas Subsidiary. In addition, J. Vernon
Hinely and/or companies owned by his sons will have an option to purchase CIC's
dry ice operations in Miami and Jacksonville, Florida.

         On December 1, 1996, Airgas acquired the pipeline that supplies natural
carbon dioxide to CIC's natural source facility in Star, Mississippi. This
source of carbon dioxide gas is one of two major sources of supply for CIC. In
July 1996 (before the acquisition by Airgas was completed), CIC amended its
supply contract to increase the supply of carbon dioxide it receives from the
pipeline. Under the contract, CIC has the right to purchase natural carbon
dioxide at prices set forth in the contract, based in part on the volume of
carbon dioxide purchased, until July 1, 2016. See "The Merger - Interests of
Certain Persons in the Merger."

Indemnification; Lockup/Escrow Agreement

         After payment of the Lockup/Escrow Fee, 55% of each CIC shareholders'
Merger Consideration (subject to adjustment up to 57% in the event of proration
in the payment of the Cash Consideration), which is the portion of the Merger
Consideration as to which cash may not be elected or paid, will be deposited
with a lockup/escrow agent pursuant to the terms of the Lockup/Escrow Agreement
for up to two years, or, in certain instances, longer. The CIC shareholders will
indemnify Airgas to the extent of up to $5,000,000 (after giving effect to a
$500,000 deductible) of the Merger Consideration deposited with the
lockup/escrow agent against claims made by Airgas within one year of the Closing
Date with respect to certain losses or damages resulting from a breach by CIC of
any warranty, representation or covenant in connection with the Merger Agreement
or any related document, for any decrease in tax benefits to the Airgas
Subsidiary resulting from an adjustment with respect to any tax returns filed by
CIC on or prior to the Closing Date and for certain other matters specified in
the Merger Agreement. Limited types of claims may not be subject to the
deductible or the $5,000,000 cap. If indemnification claims are successfully
made by Airgas, the CIC shareholders may not receive a portion of the Merger
Consideration deposited by them with the lockup/escrow agent. Another purpose of
the Lockup/Escrow Agreement is to support the tax treatment of the Merger
described herein. See "The Merger - Lockup/Escrow Agreement."

                                       15
<PAGE>
 
Shareholder Rights Under Delaware Law

         If the Merger is consummated, holders of shares of CIC Common Stock
will become holders of Airgas Common Stock, which will result in their rights as
stockholders being governed by Delaware law. A discussion of the material
differences between the rights of holders of CIC Common Stock under Florida law
and Airgas Common Stock under Delaware law is set forth in "The Merger -
Comparison of Stockholders' Rights."

Fluctuations in Market Price of Airgas Common Stock

         The market value of Airgas Common Stock after the completion of the
Merger will depend upon, and is expected to fluctuate with, among other things,
the performance of Airgas, conditions (economic or otherwise) affecting the
industrial gas distribution and industrial equipment distribution industries,
interest rates, market conditions and other factors that generally influence the
prices of securities.

         The Average Airgas Price was established at $________ pursuant to the
Merger Agreement. Between the time at which this price was determined and the
time at which the CIC shareholders actually receive their Stock Consideration,
the market value of Airgas Common Stock may fluctuate so that the value of the
shares of Airgas Common Stock to be received as consideration in the Merger by
the CIC shareholders may be greater or less than the Average Airgas Price. In
particular, Stock Consideration that is subject to the Lockup/Escrow Agreement
which will (except in the case of holders of De Minimis Shares) be at least 55%
but no more than 57% of a CIC shareholder's Merger Consideration, will be held
pursuant to the Lockup/Escrow Agreement for as long as two years from the date
of the Merger, or, in certain instances, longer, during which time the market
value of the Airgas Common Stock may rise and fall but the CIC shareholders will
not be able to sell those shares. See "The Merger - Lockup/Escrow Agreement."

         Related to this point, if Airgas is entitled to indemnification
pursuant to the Merger Agreement, such indemnification will be satisfied from
the shares of Airgas Common Stock that are subject to the Lockup/Escrow
Agreement (subject generally to a $500,000 deductible and a $5,000,000 cap).
Because such shares of Airgas Common Stock will be valued at the Average Airgas
Price for purposes of satisfying indemnification claims, satisfaction of
indemnification claims using Airgas Common Stock that has a market value of more
than the Average Airgas Price at the time of satisfaction will result in the CIC
shareholders paying more to satisfy the indemnification claim than the actual
amount of the claim. Similarly, however, satisfaction of indemnification claims
using Airgas Common Stock that has a market value of less than the Average
Airgas Price at the time of satisfaction will result in the CIC shareholders
paying less to satisfy the claim than the actual amount of the claim.


                              THE SPECIAL MEETING


Purpose of the Meeting; Date, Time and Place of Meeting
             
         The CIC Special Meeting will be held on May 28, 1997 at 1:00 p.m., at
the offices of Osburn, Henning and Company, 617 East Colonial Drive, Orlando,
Florida. The purpose of the Special Meeting is to consider and vote upon a
proposal to approve the Merger Agreement and the Merger.      

                                       16
<PAGE>
 
Record Date and Outstanding Shares
             
         Shareholders of record of CIC Common Stock at the close of business on
May 6, 1997 (the "CIC Record Date") are entitled to notice of and to vote at
the CIC Special Meeting. On the CIC Record Date, 262 shares of Class A
Common and four shares of Class B Common were outstanding and entitled to
vote at the Special Meeting. Each share of Class A Common and each share of
Class B Common entitles the holder to one vote. The presence, in person or by
proxy, of holders of a majority of the Class A Common and the holders of a
majority of the Class B Common will constitute a quorum for purposes of the
meeting. Abstentions will be treated as present for purposes of determining the
presence of a quorum.      

Proxies and Votes Required

         Approval of the Merger Agreement and the Merger requires the
affirmative vote of a majority of the outstanding shares of Class A Common and
the affirmative vote of a majority of the outstanding shares of Class B Common,
each class voting separately. Shares of CIC Common Stock which are represented
by properly executed proxies, unless such proxies shall have previously been
properly revoked, will be voted in accordance with the instructions indicated in
such proxies. If no contrary instructions are indicated, such shares will be
voted FOR approval of the Merger Agreement and the Merger. Because the approval
of the Merger Agreement and the Merger by CIC shareholders requires the
affirmative vote of a majority of the outstanding shares of Class A Common and
the affirmative vote of a majority of the outstanding shares of Class B Common,
failure to submit a proxy and an abstention will have the same effect as a vote
against approval of the Merger Agreement and the Merger.

         The Special Meeting may be adjourned to another date and/or place for
any proper purpose including, without limitation, for the purpose of soliciting
additional proxies.

         Any CIC shareholder may revoke a proxy at any time before it is voted
by filing with CIC an instrument revoking the proxy or by returning a duly
executed proxy bearing a later date, or by attending the Special Meeting and
voting in person. Any such filing should be made to the attention of John A.
Toepke, Executive Vice President, Carbonic Industries Corporation, 3700
Crestwood Parkway, Suite 200, Duluth, Georgia 30136-5583. Presence at the
Special Meeting will not revoke a shareholder's proxy unless the shareholder
votes in person.

         CIC SHAREHOLDERS SHOULD NOT FORWARD ANY STOCK CERTIFICATES WITH THEIR
PROXY CARDS. CIC STOCK CERTIFICATES SHOULD BE FORWARDED TO THE EXCHANGE AGENT
ONLY WITH THE FORM OF CASH ELECTION/TRANSMITTAL LETTER OR CLASS B TRANSMITTAL
LETTER INCLUDED WITH THIS PROXY STATEMENT/PROSPECTUS. SEE "MERGER-ELECTION
PROCEDURES" FOR INFORMATION ABOUT RETURNING YOUR STOCK CERTIFICATES.

         The directors and executive officers of CIC, who currently own in the
aggregate approximately 18% of the outstanding Class A Common and 80% of the
outstanding Class B Common, have advised CIC that they presently intend to vote
their shares in favor of the Merger Agreement and the Merger, although they are
not required to do so.

         See "The Merger -- Dissenters' Rights."

Solicitation of Proxies

         CIC will bear the costs of solicitation of proxies for its Special
Meeting. In addition to solicitation by mail, directors, officers and employees
of CIC may solicit proxies from its shareholders by telephone, telegram or in
person. Such persons will not receive additional compensation for such
solicitation.


                        BACKGROUND AND RELATED MATTERS


Background

         From time to time, and on various occasions, during approximately the
past 10 years, members of Airgas' management, including Peter McCausland,
Chairman and Chief Executive Officer, have spoken and visited with the members
of CIC management, specifically, J. Vernon Hinely, Chairman and President, for
the purpose of expressing interest in exploring a possible business combination
of Airgas and CIC. Such discussions were general in nature and each resulted in
CIC expressing reluctance to engage in any serious discussions with Airgas.

         During 1995, the Board of Directors of CIC began informal discussions
of ways to maximize shareholder value in light of developments in CIC's business
and operations. Major factors affecting this discussion included the success of
the joint venture facility with Arcadian Corporation at Augusta, Georgia, the
initiation of discussions with Arcadian Corporation for the expansion of the
joint venture's operations, the expansion of operations at the Star, Mississippi
production facility and the apparent course of multi-district anti-trust
litigation involving CIC's major competitors.

         At the November 16, 1995 CIC board meeting, the directors of CIC asked
that management explore strategic options for CIC. During December 1995, Mr.
Hinely became ill and required major heart surgery. This fact and the resulting
limitation of his participation in CIC affairs during his recuperation, as well
as continuing developments in the factors mentioned above, caused the Board of
Directors to focus even more closely on exploring strategic options.

         At the April 2, 1996 CIC board meeting, the directors considered
information concerning several options, including increasing dividends, an
initial public offering of CIC's capital stock, a leveraged recapitalization, a
sale of CIC or a merger with another company.

         All of the directors of CIC were also serving as directors of Tomco\2\
Equipment Company ("Tomco"), a former subsidiary of CIC which was "spun off" as
of December 31, 1992. The Board of Directors of CIC was aware that, while not
precisely identical, the stockholders of the two companies were substantially
similar. In a meeting also held on April 2, 1996, the Tomco Board also
considered strategic options for that company, in part with awareness of the
possible correlations between such options for both Tomco and CIC.

         As a result of these meetings and discussions, on April 22, 1996, Mr.
Hinely contacted John Winn, President of Southeast Airgas, Inc. in Atlanta,
Georgia (an Airgas subsidiary) to determine if Airgas might have an interest in
acquiring Tomco.

                                       18
<PAGE>
 
         On May 1, 1996, Mr. Hinely, who also is Chairman of the Board of Tomco,
accompanied by Jack Toepke, Executive Vice President of CIC and President of
Tomco, met with Mr. Winn and Les Graff, Assistant Vice President-Corporate
Development of Airgas, in Atlanta. As a result of this meeting, Tomco management
was instructed to provide Airgas with appropriate financial data and profile
information regarding Tomco. Sandra Fowler Hurt, Treasurer of CIC and Vice
President - Finance of Tomco, prepared and compiled this information, which was
delivered to Airgas. Airgas signed a Confidentiality Agreement at the same time.

         On July 23, 1996, Mr. Toepke and Ms. Fowler Hurt met with Mr. Winn and
Andrew Cichocki, Assistant Vice President of Corporate Development of Airgas, in
Atlanta. At this meeting, Airgas indicated that it would have no interest in
acquiring Tomco without also acquiring CIC. Subsequently, Ms. Fowler Hurt
prepared similar financial and profile information regarding CIC for
presentation to Airgas.

         On August 16, 1996. Mr. Hinely and Mr. Toepke met with Gordon Keen,
Vice President of Corporate Development of Airgas, Mr. Winn, now director of
Carbon Dioxide Development for Airgas, and Mr. Cichocki to deliver the CIC
information and to initiate discussions relative to Airgas' interest in
acquiring CIC. It was decided at this time that Tomco would not be part of these
discussions. Airgas executed a Confidentiality Agreement and CIC provided Airgas
with a presentation of financial and other information compiled for the purpose
of allowing Airgas to evaluate CIC. During late August and early September 1996,
CIC provided Airgas with additional information about its business, and CIC and
Airgas executives held telephone conversations on numerous occasions.

         On September 13, 1996, Mr. Hinely and Mr. Toepke met with Brian Haley,
President, and Bill Mathews, Vice President of Finance, both of Holox, LTD, of
Norcross, Georgia in their corporate offices to deliver identical information
regarding CIC for their review and interest. Mr. Haley had previously indicated
some interest in CIC and the carbon dioxide industry to Mr. Hinely. Holox is a
regional industrial gas manufacturer, distributor and competitor of Airgas, but
is not in the carbon dioxide business. Holox is a United States subsidiary of
Hoek's Machine - en Zuurstoffabriek N.V., which trades on the Amsterdam Stock
Exchange but does not list American Depository Receipts (ADRs) in the United
States. Holox signed a Confidentiality Agreement with respect to the CIC
information it received.

         On September 18, 1996, Mr. Hinely and Mr. Toepke met with Mr. Keen, Mr.
Winn and Mr. Cichocki in Atlanta. At this meeting, Airgas presented a formal
written proposal to acquire CIC, including a detailed term sheet. Other
information, including an assumption of debt analysis, the terms of a
noncompetition agreement with Mr. Hinely and the terms of consulting agreements
for Mr. Hinely, Mr. Toepke and Ms. Fowler Hurt were also presented.

         On October 16, 1996, Mr. Hinely and Mr. Toepke met again with Mr. Haley
and Mr. Matthews of Holox, LTD. At this meeting, Mr. Haley indicated that he had
been unsuccessful in getting Holox's parent company to consider a formal offer
for CIC, and that they would need more time to see if an offer would be
forthcoming.

         On October 22, 1996, Mr. Hinely and Mr. Toepke met with Peter
McCausland, Chief Executive Officer of Airgas, Mr. Keen, Mr. Winn and Mr.
Cichocki in Atlanta. Mr. Hinely and Mr. Toepke proposed certain amendments to
the original Airgas proposal, which included the valuation of CIC shares, the
tax

                                       19

consequences of a merger, various employment and non-competition issues, and the
the possibility of a transfer of all the dry ice customers in Jacksonville and
Miami to Florida Carbonic Inc. of Orlando, Florida, a business owned by Mr.
Hinely's sons, with the present profits of the two dry ice operations split
between CIC and Florida Carbonic Inc. Mr. McCausland countered this proposal
with slightly different terms set forth in a Letter of Intent the following day.

         On October 24, 1996, the Board of Directors of CIC held a telephonic
meeting to consider the Letter of Intent presented by Airgas. The Board
authorized Mr. Hinely and Mr. Toepke to pursue the transaction, subject to
certain modifications. Immediately following this meeting, Mr. Hinely, Mr.
Toepke and other CIC representatives met telephonically with Messrs. Keen and
Cichocki to discuss changes to the Letter of Intent.

         On October 25, 1996, Mr. Hinely and Mr. Toepke met with representatives
of Jefferson Pilot Life Insurance Company ("Jefferson Pilot") in Greensboro,
North Carolina, to inform Jefferson Pilot of the Airgas offer. Jefferson Pilot
is CIC's primary lender and its single largest shareholder.

         During the next three days, numerous telephone conversations were held
between the representatives of CIC and Airgas and a revised Letter of Intent was
presented to CIC by Airgas. On October 28, 1996, the Letter of Intent was signed
by Mr. Hinely and his brother, Herbert Hinely, on behalf of CIC and themselves
as the holders of all Class B CIC Common Stock. Airgas issued a press release
announcing the signing of the Letter of Intent on October 29 and Mr. Hinely
mailed a notice of the event to all the CIC shareholders immediately thereafter.

         On November 21, 1996, the CIC Board of Directors met and reaffirmed the
earlier decision to proceed with the transaction in accordance with the revised
Letter of Intent.

         Beginning in November 1996, Airgas management visited CIC's offices and
operating locations on numerous occasions to conduct its due diligence
investigation of CIC and Airgas' attorneys provided CIC with a draft of the
proposed Merger Agreement on November 20, 1996. Thereafter, representatives of
CIC and Airgas held detailed negotiations about the Merger Agreement, including,
but not limited to, financial structure, treatment of stock options, scope of
representations and warranties, indemnification, certain employee benefits and
management compensation.

         On December 9, 1996, at a regular meeting of Airgas' Board of
Directors, Airgas' management reported on the progress of negotiations and due
diligence. Following discussions, the Airgas Board of Directors authorized
management to conclude negotiations and execute the Merger Agreement.

         On February 20, 1997, the CIC Board of Directors elected Robert F.
Harkrider to the Board of Directors to fill the vacancy left by W. Herbert
Hinely, who passed away in December 1996. On February 25, 1997, the CIC Board of
Directors held a special meeting to discuss the progress of the Merger
negotiations and the proposed terms of the Merger Agreement. After discussions
focusing on issues related to the determination of the Airgas Average Price, the
Board authorized management to continue its negotiations and to finalize the
Merger Agreement in accordance with the Board's instructions.

         On March 12, 1997, the Board of Directors of CIC held a special meeting
of the Board to consider the proposed terms of the transaction. At this meeting,
members of CIC's management, together with its legal advisers, discussed again
the strategic rationale for the Merger, the proposed terms of the Merger and the
potential benefits and disadvantages of the proposed transaction to CIC and its
shareholders. At the

                                       20
<PAGE>
 
conclusion of this meeting, the Board of Directors unanimously adopted the
Merger Agreement, resolved that the Merger Agreement and the actions
contemplated thereby should be submitted to the shareholders of CIC for approval
with the Board's recommendation, and authorized the officers of CIC to execute
the Merger Agreement, which was executed on March 12, 1997.

         On April 16, 1997, the Airgas Board of Directors held a special meeting
to authorize the issuance of the Airgas Common Stock in the Merger.

CIC's Reasons for the Merger; Recommendation of the Board of Directors

         At its March 12, 1997 meeting, the CIC Board determined that the Merger
is advisable and in the best interests of CIC and its shareholders, and
unanimously approved the Merger and the Merger Agreement. The Board of Directors
unanimously recommends that the CIC shareholders vote FOR approval of the Merger
Agreement. The Board considered the following factors, which are not set forth
in any particular order of importance, in making its determination.

         1. Mr. Vernon Hinely, CIC's founder, President and Chairman of the
Board of Directors, has, for health-related reasons, temporarily limited some of
his active participation in CIC's affairs. Mr. Hinely has been one of the most
significant driving forces behind CIC's successes and has extensive experience,
knowledge and repute within the carbon dioxide industry. The Board believes it
would be extremely difficult to replace Mr. Hinely should he be required to
scale back his involvement with CIC, but that, if CIC were part of the larger
operations of Airgas, there is greater likelihood of attracting additional
strong new leadership than were CIC to undertake the task alone.

         2. CIC is currently experiencing growth, and the Board and management
anticipates that there will be a continuing need for additional capital to
maintain that growth and take advantage of other growth opportunities. In
particular, the AC Industries joint venture is experiencing significant success
and expansion of AC Industries is underway. Additionally, CIC recently
negotiated a new agreement at its Star, Mississippi natural-source facility that
allows CIC to take significant quantities of additional raw carbon dioxide from
the pipeline. The latter agreement was completed before Airgas acquired the
pipeline source in December 1996. In addition, partly as a result of certain
anti-trust litigation involving a number of CIC's major competitors, the Board
believes that CIC is developing, and has the potential to develop, expanded and
additional relationships with major carbon dioxide customers, both within and
beyond CIC's current market areas. The Board believes that Airgas has greater
access to capital than does CIC, which would enable CIC to exploit these
opportunities efficiently and economically. The Board believes that the
businesses of the companies are compatible and that, accordingly, a business
combination of CIC and Airgas will allow the combined entity to exploit the
possibilities for significant growth in the carbon dioxide industry and achieve
an improved competitive position under current market conditions.

         3. Airgas is a publicly traded company, which will provide CIC
shareholders who receive Airgas stock greater liquidity than they currently have
with CIC Common Stock and an equity interest in a larger company.

         4. The Board believes that the consideration to be paid for the CIC
Common Stock will, for many CIC shareholders, represent a significant return on
their initial investment in the stock. The opportunity for shareholders to
receive a tax-free exchange of CIC Common Stock for Airgas Common Stock for
federal income tax purposes should be of considerable value to many CIC
shareholders.

                                       21
<PAGE>
 
         5. The Board believes that the Merger offers a favorable return on
investment for CIC shareholders in consideration of all the circumstances.
Airgas originally proposed a total consideration for all the outstanding CIC
Common Stock of approximately $56.4 million, of which approximately $37 million
(66%) would be paid for Class A Common (assuming the exercise of all options to
acquire Class A Common), approximately $5.1 million (10%) for Class B Common and
approximately $14.2 million (25%) would be by the assumption by Airgas of CIC
debt. The Board negotiated an increase of approximately $1.8 million, all of
which was allocated to the Class A Common (assuming exercise of the above
mentioned options). This results in a price per share of $43.00 per share for
Class A Common and $205.00 per share for Class B Common. The holders of the
Class B Common, some of whom also hold Class A Common, will receive a total of
approximately $5.1 million for all of their Class B Common. They will also
receive an additional amount of approximately $3.1 million for all of their
Class A Common (assuming their outstanding options to acquire Class A Common are
exercised prior to the Merger) for an aggregate consideration to those
shareholders of approximately $8.2 million (14.1%) of the total consideration.
The Board concluded that this consideration, which was proposed by Airgas and
which represents Airgas' assessment of the relative value of the two classes of
stock, was appropriate for the following reasons:

                  (a)  The $43.00 price per share for Class A Common represents
         a substantial premium over its December 31, 1996 book value, $17.52.
         Management believes Class A Common has historically been purchased and
         sold at book value, with one or two exceptions.

                  (b)  Management believes that much of the Class A Common
         carries its original tax basis of less than $2.00 per share in the
         hands of its holders; thus a tax-free exchange for federal tax purposes
         may represent a substantial benefit to many shareholders when compared
         to a currently taxable transaction at the same nominal share value.

                  (c)  The holders of Class B Common are entitled, under the
         terms of CIC's articles of incorporation, to elect a majority of the
         Board of Directors and thus control the Board of Directors. In
         addition, it is the view of the Board of Directors that the holders of
         Class B Common, under the terms of Florida law, must vote on
         significant corporate actions (including the Merger) as a separate
         class. This means that Class B Common has special rights that are
         consistent with a higher price per share, or a "control premium."

         6. Management had approached what CIC considered the most likely
candidates for an acquisition, Airgas and Holox. The other possible candidate,
Holox, has not submitted a specific acquisition proposal. Even if a proposal had
been submitted by Holox, because that company is foreign-owned, any proposal
was unlikely to be advantageous enough to outweigh the benefits of a tax-free
transaction with a company whose shares were more readily tradable.

         In making its decision, the CIC Board also considered as negative
factors that subsequent to the Merger CIC shareholders will no longer receive a
dividend with respect to their stock, since historically Airgas has not paid
dividends on its Common Stock, and that by virtue of the Merger and the
characteristics of Airgas' capital structure, the CIC shareholders would have a
minority voting interest in the combined enterprise.

         There were no other material factors considered by the CIC Board in
reaching its decision. In view of the wide variety of factors considered in
connection with its evaluation of the Merger, the Board

                                       22
<PAGE>
 
of Directors did not find it practicable to, and did not, quantify or otherwise
attempt to assign relative weights to the specific factors considered in
reaching its decision.

         For the reasons set forth above, CIC's Board of Directors voted
unanimously to approve the Merger Agreement and the Merger and unanimously
recommends that the holders of CIC Common Stock vote FOR approval of the Merger
Agreement and the Merger.

Airgas' Reasons for the Merger

         The Board of Directors of Airgas has unanimously approved the Merger
Agreement and the Merger and, for the reasons set forth below, believes that the
Merger is in the best interests of Airgas and its stockholders.

         The Board believes that the Merger will significantly expand growth
opportunities for each of CIC and Airgas within the carbon dioxide industry, and
the Board believes CIC's established presence in the carbon dioxide industry
will complement Airgas' national distribution network. In reaching the
conclusion, the Airgas Board of Directors considered a number of factors
including the following:

         1. Airgas has an established distribution network for cylinder gases
throughout the United States and Southern Canada. Using that network, Airgas
already is a distributor of carbon dioxide gases in small quantities (small
bulk, beverage mini-bulk, cylinder gases and dry ice). Airgas currently
purchases carbon dioxide from various producers, including CIC in the
Southeastern United States, and redistributes the product to small-quantity
users. Airgas currently has no production capability. The Board considered CIC's
established production capabilities and production technology as a natural
complement to Airgas' distribution capabilities. The Board considered that CIC
would give Airgas the ability to independently source carbon dioxide, and
possibly negotiate contractual supply agreements with other carbon dioxide
producers in order to meet a portion of Airgas' demands for carbon dioxide
throughout the United States. CIC would also bring to Airgas applications
technologies and expertise in the food industry (specifically refrigeration,
freezing and packaging) that would potentially allow Airgas to accelerate its
growth in the carbon dioxide business outside of its current focus on
traditional welding applications.

         2. The complementary nature of CIC's and Airgas' businesses would
provide expanded growth opportunities for both companies. CIC would be able to
leverage Airgas' expansive customer base to gain access to a large number of
potential new customers, an opportunity CIC does not currently possess on its
own. Additionally, a combination of Airgas and CIC would provide Airgas with
additional growth opportunities through potential acquisitions of regional bulk
carbon dioxide distribution companies as well as large beverage distribution
businesses.

         3. CIC is a strong, well managed, highly profitable company that has
successfully demonstrated consistent growth in a highly competitive industry.
CIC would bring to Airgas a highly qualified team of managerial talent and an
entrepreneurial history. J. Vernon Hinely, CIC's Chairman and President, is
highly respected in the carbon dioxide industry and would bring to Airgas a
measure of immediate credibility within the field.

         4. The Airgas Board considered the potential increase in stockholder
value that could result from the strength and growth opportunities of the
combined companies. Although the Merger would

                                       23
<PAGE>
 
result in a minor dilution to Airgas' earnings per share in the first year of
combined operations, the future expected accretion in earnings and cash flow, as
well as an opportunity for accelerated growth, would make the Merger an
attractive transaction for Airgas.

         After taking into consideration all of the factors set forth above,
each of which was considered by Airgas' Board to support the Board's approval of
the Merger, the Board of Directors determined that the Merger was in the best
interests of the stockholders of Airgas. In reaching this determination, the
Airgas Board considered numerous factors, including those listed above, as well
as the terms and conditions of the Merger Agreement and information with respect
to the financial condition, business operations and prospects of CIC, on both an
historical and prospective basis. In view of the wide variety of factors
considered in connection with its evaluation of the Merger, the Board of
Directors did not find it practicable to, and did not, quantify or otherwise
attempt to assign relative weights to the specific factors considered in
reaching its decision.


                                  THE MERGER


         This section of the Proxy Statement/Prospectus is not a complete
explanation or description of the Merger Agreement. It is qualified in its
entirety by reference to the complete text of the Merger Agreement, a copy of
which is attached to this Proxy Statement/Prospectus as Appendix A.

Effect of Merger

         The Merger Agreement provides that when the Merger becomes effective
the separate existence of CIC will cease and it will be merged with and into
Airgas Subsidiary, with Airgas Subsidiary as the surviving corporation. Airgas
Subsidiary has been formed solely for the purpose of effecting the Merger, has
conducted no business and has no material assets or obligations other than the
Merger Agreement. All of the properties, rights, privileges and powers of Airgas
Subsidiary and CIC will be vested or continue to be vested in Airgas Subsidiary
and be subject to all of the obligations of the Airgas Subsidiary and CIC.

         If the Merger Agreement is approved by the CIC shareholders, the Merger
will be effective on the date that the Certificate of Merger is filed with the
Secretary of the State of Delaware, provided that Articles of Merger are filed
with the Department of State of Florida (the "Effective Time"). The foregoing
filings are expected to be made on the Closing Date.

         It is currently expected that the Merger will occur during the quarter
ending June 30, 1997. Either party may terminate the Merger Agreement if the
Merger has not occurred on or before August 31, 1997.

Conversion of Shares and Fractional Shares

         At the Effective Time, each outstanding share of Class A Common (other
than shares as to which dissenters' rights have been perfected under Chapter 607
of the FBCA) will be converted, subject to proration and other limitations
described herein, at the election of the holder, into the right to receive (i)
the Class A Stock Consideration or (ii) the Class A Cash Consideration, and each
outstanding share of

                                      24
<PAGE>
 
Class B Common will be converted into the right to receive (i) the Class B Stock
Consideration or (ii) the Class B Cash Consideration.

         Class A Common. Each share of Class A Common will be converted into the
         --------------
right to receive, at each holder's election but subject to proration and other
limitations, as described below, either the Class A Stock Consideration or the
Class A Cash Consideration. The Class A Stock Consideration will be equal to
that number of shares of Airgas Common Stock equal to the quotient of $43.00
divided by $__________ (the Class A Exchange Ratio).

         The right of holders of Class A Common to elect to receive the Class A
Cash Consideration in the amount of $43.00 for each share of Class A Common in
lieu of Class A Stock Consideration will be subject to proration and other
limitations described herein and in the Merger Agreement, which provide
generally that (i) the Class A Cash Consideration to be received by each holder
cannot exceed 45% of the value of each of such holders' shares of Class A Common
and (ii) the Aggregate Cash Consideration cannot exceed the Aggregate Stock
Consideration (i.e. more than 50% of the Merger Consideration with allowance
made for dissenters' rights, if any); although the proration and other
limitations do not apply to the De Minimis Shares, as to which a holder may
elect to receive 100% of his or her Merger Consideration in Class A Cash
Consideration.

         Class B Common. Each share of Class B Common will be converted into the
         --------------
Class B Stock Consideration or the Class B Cash Consideration. The Class B Stock
Consideration will be equal to that number of shares of Airgas Common Stock
equal to the quotient of $205.00 divided by $__________________ (the Class B
Exchange Ratio).

         The Class B Cash Consideration will be equal to $205.00 for each share
of Class B Common. Each holder of shares of Class B Common will receive the
Class B Cash Consideration for 45% of the value of such holder's shares of Class
B Common and the Class B Stock Consideration for 55% of his or her Class B
Common, subject to the proration described below.

         Proration. The Aggregate Cash Consideration cannot exceed the Aggregate
         ---------
Stock Consideration (i.e. more than 50% of the Merger Consideration). If the
Aggregate Cash Consideration does not exceed the Aggregate Stock Consideration,
each share of Class A Common for which a valid Cash Election is received, up to
45% of the value of a holder's shares of Class A Common, will be converted in
the Merger into the right to receive the Class A Cash Consideration and 45% of
the value of the Class B Common will be converted into the right to receive the
Class B Cash Consideration. However, if the Aggregate Cash Consideration would
(but for the adjustment described below) exceed the Aggregate Stock
Consideration, the holder's percentage of Merger Consideration being paid as
Cash Consideration will be reduced pro rata on a basis proportionate with the
other CIC shareholders' cash percentage until the Aggregate Stock Consideration
is equal to or exceeds the Aggregate Cash Consideration, provided that a
holder's percentage of Cash Consideration cannot be reduced by more than two
percentage points and that this proration does not apply to the De Minimis
Shares. The Exchange Agent will distribute the Stock Consideration for any
shares of CIC Common Stock which are not fully converted into the right to
receive the Cash Consideration.

         In the event that between the date of the Merger Agreement and the
Effective Time, the number of issued and outstanding shares of Airgas Common
Stock is changed into a different number of shares or a different class of
shares as a result of a stock split, reverse stock split, stock dividend,
spin-off,

                                      25
<PAGE>
 
extraordinary dividend, recapitalization, reclassification or other similar
transaction with a record date within such period, the Stock Consideration and
the Cash Consideration will be appropriately adjusted.

         AS A RESULT OF THE PRORATION AND OTHER LIMITATIONS DESCRIBED HEREIN AND
IN THE MERGER AGREEMENT, HOLDERS OF SHARES OF CLASS A COMMON WHO ELECT TO
RECEIVE THE CASH CONSIDERATION MAY RECEIVE SHARES OF AIRGAS COMMON STOCK OR THE
CASH CONSIDERATION IN AMOUNTS THAT MAY VARY FROM THE AMOUNTS SUCH HOLDERS ELECT
TO RECEIVE. SUCH HOLDERS WILL NOT BE ABLE TO CHANGE THE AMOUNTS OF AIRGAS COMMON
STOCK OR THE CASH CONSIDERATION ALLOCATED TO THEM.
    
         Fluctuations in Merger Consideration. On May __, 1997, the most
         ------------------------------------                                   
recent practicable date prior to the date of this Proxy Statement/Prospectus,
the closing sale price of the Airgas Common Stock on the NYSE was $____ per
share. The market price of the Airgas Common Stock will depend on, and is
expected to fluctuate with, among other things, the performance of Airgas,
conditions (economic or otherwise) affecting the industrial gas and equipment
distribution industries, interest rates, market conditions and other factors
that generally influence the prices of securities. See "Investment
Considerations - Fluctuations in Market Price of Airgas Common Stock."

         Fractional Shares. No fractional shares of Airgas Common Stock will be
         -----------------
issued in connection with the Merger. The number of shares of Airgas Common
Stock issued to each CIC shareholder will be rounded up to the nearest whole
number of shares.

Election Procedures

         Elections. The Merger Agreement provides that each holder of shares of
         ---------
Class A Common (other than treasury stock and shares that are owned by CIC,
which shares will be cancelled and retired, without consideration, at the
Effective Time, and shares as to which dissenters' rights have been exercised in
accordance with and subject to the provisions of the FBCA) has the right,
subject to the proration and other limitations described below, to submit a
request specifying the number of shares of Class A Common owned by such holder,
up to 45% of the value of each holder's shares, which such holder desires to
have converted into cash in an amount equal to the Class A Cash Consideration
(except that such prorations and limitations do not apply to the De Minimis
Shares, as to which a 100% Cash Election may be made) (the "Cash Election").

         All Cash Elections must be made on the Form of Cash Election, a copy of
which is being mailed simultaneously with this Proxy Statement/Prospectus, and
must be received and accepted by the Cash Election Deadline. Additional copies
of the Form of Cash Election will be available upon request from the Bank of New
York, which will be serving as the Exchange Agent (the "Exchange Agent"), by
calling Richard Hanrahan at (212) 815-2444.

         The purpose of the Cash Election is to permit holders of shares of
Class A Common to express their preferences for the type of consideration they
wish to receive in the Merger, provided that (i) holders do not have the right
to request Cash Consideration for more than 45% of the value of their shares of
Class A Common (except with respect to the De Minimis Shares) and (ii) the
Aggregate Cash Consideration cannot exceed the Aggregate Stock Consideration. As
discussed below, subject to the

                                      26
<PAGE>
 
proration and other limitations described herein, Cash Elections made by holders
of Class A Common will be honored in issuing the Class A Cash Consideration
after the Effective Time.

         ALTHOUGH THERE CAN BE NO ASSURANCE THAT A HOLDER OF SHARES OF CLASS A
COMMON WHO DESIRES TO RECEIVE THE CASH CONSIDERATION WILL RECEIVE SUCH
CONSIDERATION TO THE FULL EXTENT REQUESTED, A HOLDER OF SHARES OF CLASS A COMMON
HAVING A PREFERENCE FOR THE CASH CONSIDERATION SHOULD MAKE AN ELECTION BECAUSE
SHARES AS TO WHICH AN ELECTION HAS NOT BEEN MADE WILL RECEIVE THE STOCK
CONSIDERATION IN THE MERGER. NEITHER THE CIC BOARD OF DIRECTORS NOR THE AIRGAS
BOARD OF DIRECTORS MAKES ANY RECOMMENDATION AS TO WHETHER THE SHAREHOLDERS
SHOULD ELECT TO RECEIVE THE CASH CONSIDERATION OR THE STOCK CONSIDERATION IN THE
MERGER. EACH SHAREHOLDER MUST MAKE HIS OR HER OWN DECISION WITH RESPECT TO SUCH
ELECTION.

         Failure of a holder of shares of Class A Common to complete properly
and to return the Form of Cash Election to the Exchange Agent by the Cash
Election Deadline, or failure to comply with the election procedures described
in this Proxy Statement/Prospectus and the Form of Cash Election (including the
instructions thereto), will cause all of such holder's shares of Class A Common
to be converted into the Class A Stock Consideration without regard to the
preference of such holder.

         Completing the Form of Cash Election. To make a proper Cash Election, a
         ------------------------------------
holder of shares of Class A Common must have delivered to the Exchange Agent at
the address specified in the Form of Cash Election, prior to the Cash Election
Deadline, a Form of Cash Election properly completed in accordance with the
instructions thereon and signed by the record holder of the shares of Class A
Common as to which such election is being made.

         Irrevocability of Cash Elections. Forms of Cash Election will become
         --------------------------------
irrevocable upon receipt by the Exchange Agent, unless the Exchange Agent, in
its sole discretion, permits their amendment or withdrawal. However, all Cash
Elections will be revoked automatically if the Exchange Agent is notified in
writing by Airgas or CIC that the Merger Agreement has been terminated.

         Other Rules. Airgas and CIC have the right to make rules, not
         -----------
inconsistent with the terms of the Merger Agreement, governing the validity of
any Form of Cash Election, the manner and extent to which Cash Elections are to
be taken into account in making the determinations required by the Merger
Agreement, the issuance and delivery of certificates for Airgas Common Stock for
shares of CIC Common Stock converted into such stock in the Merger and the
payment of cash for shares of Class A Common converted into the right to receive
the Cash Consideration in the Merger.

         Delivery of CIC Common Stock Certificates. Certificates representing
         -----------------------------------------
the shares of Class A Common and shares of Class B Common to be converted into
the right to receive the Merger Consideration should be surrendered by the Class
A Common holders together with a completed and signed Form of Cash Election and
the Class B Common holders together with the Class B Transmittal Letter, copies
of which are enclosed with this Proxy Statement/Prospectus, as applicable.

         Delivery of Merger Consideration.  Promptly after the later of the
         --------------------------------
Effective Time and the delivery by a holder of the certificates representing the
CIC Common Stock and the Form of Cash

                                      27
<PAGE>
 
Election or Class B Transmittal Letter, as applicable, to the Exchange Agent,
the Exchange Agent will distribute to the holder certificates representing the
number of shares of Airgas Common Stock (excluding the shares subject to the
Lockup/Escrow Agreement) into which the shares of CIC Common Stock were
converted, plus cash in the amount of the Cash Consideration into which such
holder's shares were converted (provided that a holder of Class A Common has
made a valid Cash Election). The Exchange Agent will also deliver to the
lockup/escrow agent certificates representing shares of Airgas Common Stock
subject to the Lockup/Escrow Agreement and will deliver to the CIC Shareholders'
Agent Committee (as defined below) the Lockup/Escrow Fee of 0.25% of each CIC
shareholder's Merger Consideration to be placed in the Fees & Expenses Fund. The
fund will be used to cover fees, costs, expenses and contingencies arising under
the Lockup/Escrow Agreement and any other related agreement. To the extent that
any monies in the fund are not used to satisfy such costs and expenses, they
will be distributed to the former CIC shareholders, on a pro rata basis. Until
surrendered, each outstanding certificate that represented shares of CIC Common
Stock prior to the Effective Time will be deemed for all corporate purposes to
evidence the right to receive the Merger Consideration into which such shares of
CIC Common Stock have been converted, but will not entitle the holder to receive
dividends or other distributions from Airgas or to vote such shares.

Continuity of Interest Certificates

         Receipt of Continuity of Interest Certificates from CIC shareholders
who will deposit shares of Airgas Common Stock into the Lockup/Escrow Fund which
in the aggregate represent not less than 50% of the Merger Consideration is a
condition to the consummation of the Merger. Holders of CIC Common Stock should
return their completed and executed Continuity of Interest Certificates to CIC,
together with their proxies, but in any event prior to the Closing of the
Merger. If CIC does not receive such certificates, the Merger may not be
consummated. The purpose of the certificate is to support the tax treatment of
the Merger described herein.

CIC Employee Options

         Effective upon consummation of the Merger, Airgas will assume options
to acquire CIC Common Stock granted pursuant to CIC's Incentive Stock Option
Plan, outstanding at the Effective Time (the "CIC Stock Options"). Thereafter,
the former CIC Stock Options will, by virtue of the Merger, become exercisable
to purchase (i) that number of shares of Airgas Common Stock, rounded up to the
nearest whole share, determined by multiplying (x) the number of shares of CIC
Common Stock subject to such option immediately prior to the Effective Time by
(y) the Class A Exchange Ratio and (ii) at an exercise price per share equal to
the exercise price per share pursuant to the CIC Stock Option divided by the
Class A Exchange Ratio (rounded up or down to the nearest cent). After the
Effective Time, each of such options will be fully vested and exercisable.

Board of Directors and Management of Airgas Following the Merger

         The directors and executive officers of Airgas will continue in such
capacities following the Merger. J. Vernon Hinely and John A. Toepke will
continue to serve as executive officers of the Airgas Subsidiary, although they
will not serve as executive officers of Airgas. See "Airgas - Management."


                                      28
<PAGE>
 
         Neither Airgas nor CIC is aware of any material relationships between
Airgas or its directors or executive officers and CIC or its directors or
executive officers, except as contemplated by the Merger Agreement, or as
described herein. See "-- Interests of Certain Persons in the Merger."

Lockup/Escrow Agreement

         Except with respect to the De Minimis Shares, the Exchange Agent will
deposit with the lockup/escrow agent (the "Lockup/Escrow Agent") on behalf of
each CIC shareholder Airgas Common Stock valued at 55% (subject to adjustment up
to 57% if the Cash Consideration is prorated) of such CIC shareholder's Merger
Consideration after the reduction for the Lockup/Escrow Fee, which Airgas Common
Stock will be placed in the "Lockup/Escrow Fund."  For a Class A Common holder
electing the maximum amount of Class A Cash Consideration, this means that his
entire Class A Stock Consideration is placed in the Lockup/Escrow Fund (to the
extent a Class A Common holder elects to receive more stock and less cash, his
Class A Stock Consideration in excess of 55% (or up to 57% if prorated) is paid
directly to him).  All shares of Class B Stock Consideration will be deposited
with the Lockup/Escrow Agent.  The purpose of the Lockup/Escrow Fund is twofold:
first, to support the tax treatment of the Merger described herein (the "Tax
Purpose") and second, to provide a source for satisfaction of indemnification
claims by Airgas or its affiliates (the "Indemnification Purpose").

         Tax Purpose. Unless the Tax Purpose of the Lockup/Escrow Fund is
         -----------
earlier terminated as described below, no CIC shareholder will receive any of
his portion of the Lockup/Escrow Fund until the second anniversary of the
Effective Time. As soon as practicable after such date, each CIC shareholder's
portion of the Lockup/Escrow Fund will be distributed to him to the extent it is
not required to cover pending indemnification claims. The CIC shareholders will
have the right to vote and receive dividends with respect to the Airgas Common
Stock held in the Lockup/Escrow Fund. The Lockup/Escrow Agreement, however,
prohibits the sale, assignment, pledge or other transfer by a CIC shareholder of
his Airgas Common Stock while it is held in the Lockup/Escrow Fund. The Tax
Purpose of the Lockup Escrow Fund will terminate prior to the second anniversary
of the Effective Time if the parties obtain a legal opinion that an early
distribution will not affect the tax treatment of the Merger described herein.

         Indemnification Purpose. Shares held in the Lockup/Escrow Fund may be
         -----------------------
used to satisfy indemnification claims up to $5,000,000 (after giving effect to
a $500,000 deductible, except that certain claims, including for broker fees or
those based on fraud are not subject to the deductible or $5,000,000
limitation). Any claim for indemnification will be offset or reduced by
insurance proceeds received by Airgas or CIC as provided in the Merger
Agreement. Claims not made by Airgas within one year of the date of the Closing
will be forfeited. Timely claims that are not resolved at the time the Tax
Purpose terminates will result in a portion of the Lockup/Escrow Fund sufficient
to cover such claim (subject to any applicable cap and deductible) being held in
the Lockup/Escrow Fund until resolution of such claim. At such time, shares not
used to satisfy such claim will be distributed to the CIC shareholders.

CIC Shareholders' Agent Committee

         Upon the CIC shareholders' approval of the Merger Agreement, a
shareholders' agent committee, initially consisting of J. Vernon Hinely, John A.
Toepke and Jonathan I. Wax (together with any successors, the "CIC Shareholders'
Agent Committee") will be entitled to act on behalf of the CIC

                                      29
<PAGE>
 
shareholders in certain respects. The CIC Shareholders' Agent Committee will,
among other things, act as the CIC shareholders' representative with regard to
any claims for indemnification and may pay indemnification claims and certain
fees and expenses related to the administration of the Merger Agreement and the
Lockup/Escrow Agreement using the Fees and Expenses Fund or the Airgas Common
Stock held pursuant to the Lockup/Escrow Agreement, all in accordance with the
terms of the Merger Agreement and the Lockup/Escrow Agreement. The CIC
Shareholders' Agent Committee will be empowered to endorse over any stock
certificates held pursuant to the Lockup/Escrow Agreement to pay indemnification
claims and to supplement the Fees and Expenses Fund.

Representations and Warranties; Covenants and Agreements

         The Merger Agreement and certain documents delivered in connection with
the Merger Agreement contain representations, warranties, covenants and
agreements by CIC and Airgas regarding, among other things, the accuracy and
completeness of certain information supplied in connection with the Merger. The
Merger Agreement also provides that between the date of the Merger Agreement and
the Effective Time CIC will conduct its business only in the ordinary and usual
course of business and it will not, without Airgas' written consent, among other
things, issue any securities; except in accordance with prior practice, pay any
dividends; redeem or purchase any of its capital stock; amend its Articles of
Incorporation or Bylaws; increase the compensation payable to officers or
employees (except for increases in the ordinary course of business consistent
with past practices); enter into or amend any material agreements relating to
borrowing of money, except as may be necessary in order to consummate the Merger
or in the ordinary course of business; without providing notice to Airgas, enter
into agreements in excess of $100,000 each; transfer any intellectual property,
except in the ordinary course of business; make any material acquisitions of
assets except in the ordinary course of business; or guarantee the obligations
of others except for negotiable instruments endorsed in the ordinary course of
business.

Conditions Precedent to the Consummation of the Merger; Waiver

         The respective obligations of CIC and Airgas to consummate the Merger
are subject to a number of conditions, including (a) receipt by CIC of any
necessary approvals of its shareholders in accordance with applicable law; (b)
the absence of any order of a court, any statute, rule or regulation or
proceeding before any court or governmental or regulatory authority that
prevents or challenges consummation of the Merger; (c) the receipt of any
permits, authorizations, approvals or consents necessary from third parties or
governmental bodies; (d) the performance by CIC and Airgas of their obligations
under the Merger Agreement and the accuracy in all material respects of the
representations and warranties of CIC and Airgas contained therein; (e) the
receipt of opinions of counsel to CIC and Airgas with respect to the
organization, good standing and capital stock of CIC and Airgas, the validity
and binding effect of the Merger, and other legal matters, including an opinion
of counsel to Airgas with respect to certain tax matters; (f) the execution of
employment agreements by two former executive officers of CIC; (g) the
effectiveness of the Registration Statement of which this Proxy
Statement/Prospectus is a part; (h) the absence of any material adverse change
in the financial condition, results of operations or business of CIC or Airgas
between March 12, 1997 through the Effective Time and (i) the receipt of
Continuity of Interest Certificates in form and substance satisfactory to Airgas
and the CIC Shareholders' Agent Committee from owners of such number of shares
subject to the Lockup/Escrow Agreement which in the aggregate represent no less
than 50% of the Merger Consideration.

                                      30
<PAGE>
 
         It will not be known until immediately prior to the Effective Time
whether all of the above conditions will have been satisfied. Except with
respect to shareholder approval and other matters required by law, each of the
parties to the Merger Agreement may, at its option, waive compliance with any
condition to its obligation to consummate the Merger.

Termination and Amendment

         The Merger Agreement may be terminated at any time prior to the
Effective Time, before or after its adoption by the shareholders of CIC (a) by
mutual consent of Airgas and CIC; (b) by either Airgas or CIC if the Merger has
not been consummated by August 31, 1997; (c) by either Airgas or CIC if any
representation or warranty has been breached by the other party in any material
respect; (d) by Airgas or CIC if any condition to the other party's obligations
to effect the Merger has not been met or waived; or (e) by either Airgas or CIC
if any court has issued an order prohibiting the Merger. The Merger Agreement
may be amended by the mutual consent of Airgas and CIC at any time; provided,
however, that after approval by CIC's shareholders, no amendment may be made
which under Florida law requires further approval by the shareholders of CIC
without such further approval, such as amendments that (a) reduce or change the
form of composition of the consideration which the CIC shareholders would be
entitled to receive or (b) alter or change any term or condition that would
result in a material adverse effect on the CIC shareholders.

Interests of Certain Persons in the Merger

         At the closing of the Merger, Airgas will enter into employment
agreements with J. Vernon Hinely and John A. Toepke. Under the new employment
agreements, J. Vernon Hinely will serve as the Chairman, and John A. Toepke will
serve as Executive Vice President, of the Airgas Subsidiary. The agreements
contain confidentiality and non-competition agreements and permit the Airgas
Subsidiary to terminate the employee's employment with cause. In the event that
the employment is terminated without cause, the employee is entitled to
severance benefits equivalent to the compensation he would have received for the
remaining term of the agreement.

         All outstanding options to purchase CIC Common Stock will vest upon
consummation of the Merger. Mr. Hinely and Mr. Toepke own options to acquire
15,000 and 10,000 shares of Class A Common, respectively. In addition, J. Vernon
Hinely and/or companies owned by his sons will have an option to purchase CIC's
dry ice operations in Miami and Jacksonville, Florida. If exercised, the
purchasing company will pay a cash purchase price, enter in to a five-year
liquid carbon dioxide supply contract with Airgas and grant Airgas a right of
first refusal to acquire it or substantially all of its assets.

         On December 1, 1996, Airgas acquired the pipeline that supplies natural
carbon dioxide to CIC's natural source facility in Star, Mississippi. This
source of carbon dioxide gas is one of two major sources of supply for CIC. In
July 1996 (before the acquisition by Airgas was completed), CIC amended its
supply contract to increase the supply of carbon dioxide it receives from the
pipeline. Under the contract, CIC has the right to purchase natural carbon
dioxide at prices set forth in the contract, based in part on the volume of
carbon dioxide purchased, until July 1, 2016.

Certain Federal Income Tax Consequences of the Merger

         The following discussion is a summary of certain material U.S. federal
income tax consequences of the Merger to a shareholder of CIC that holds its
shares of CIC Common Stock as a capital asset (a "Holder"). The discussion is
based on laws, regulations, rulings and decisions in effect in the date hereof,
all of which are subject to change (possibly with retroactive effect) and
differing interpretations. This discussion is for general information only, and
does not address all aspects of federal taxation and does not address aspects of
federal income taxation that may be applicable to a Holder subject to special
treatment under the Code (including banks, tax-exempt organizations, insurance
companies, dealers in securities or foreign currency, and holders who are not
U.S. persons (as defined in section 7701(a)(30) of the Code). In addition, the
discussion does not address the state, local or foreign tax consequences of the
Merger.

         EACH HOLDER OF CIC COMMON STOCK IS URGED TO CONSULT ITS TAX
ADVISER WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF THE MERGER.

         Consummation of the Merger is conditioned upon the receipt by CIC of
the opinion of McCausland, Keen & Buckman, counsel to Airgas, dated as of the
Effective Time, substantially to the effect that, on the basis of facts,
representations and assumptions set forth or referred to in such opinion, the
Merger will be treated as a "reorganization" within the meaning of Section
368(a) of the Code. If CIC is unable to obtain an opinion from tax counsel
because of a concern that the Merger would not satisfy the "continuity of
interest" requirement for reorganization treatment, the number of shares of
Airgas Common Stock to be issued in the Merger will be increased to the minimum
extent necessary to enable such opinion(s) to be issued and the amount of
Cash Consideration will be reduced accordingly. Under the Merger Agreement there
are certain limitations on the number of shares of Airgas Common Stock that
Airgas would be required to issue. See "--Election Procedures."

         Exchange of CIC Common Stock. As discussed below, the U.S. federal
         ----------------------------
income tax consequences of the Merger to a Holder generally will depend on
whether the Holder exchanges its CIC Common Stock for cash, Airgas Common Stock,
or a combination thereof.

         Exchange Solely for Airgas Common Stock. If pursuant to the Merger, a
         ---------------------------------------
Holder exchanges all of the shares of CIC Common Stock actually owned by it
solely for shares of Airgas Common Stock, such Holder will not recognize any
gain or loss. The aggregate adjusted tax basis of the shares of Airgas Common
Stock received in that exchange will be equal to the aggregate adjusted tax
basis of the shares of CIC Common Stock surrendered therefor, and the holding
period of such Airgas Common Stock will include the period during which such
shares of CIC Common Stock were held. If the Holder has differing bases or
holding periods in respect of its shares of CIC Common Stock, it should consult
its tax adviser prior to the exchange with regard to identifying the bases or
holding periods of the particular shares of Airgas Common Stock received in the
exchange.

         Exchange for Airgas Common Stock and Cash. If pursuant to the Merger, a
         -----------------------------------------
Holder exchanges all of the shares of CIC Common Stock actually owned by it for
a combination of Airgas Common Stock and cash, such holder will realize gain or
loss equal to the difference between (i) the sum of cash and

                                      32
<PAGE>
 
the fair market value of Airgas Common Stock received and (ii) its adjusted tax
basis in the shares of CIC Common Stock surrendered. Such gain will only be
recognized to the extent of the cash received, however, and no loss will be
recognized on the exchange. For this purpose, gain or loss must be calculated
separately for each identifiable block of shares surrendered in the exchange,
and a loss realized on one block of shares cannot be used to offset a gain
realized on another block of shares. Any recognized gain will generally be
long-term capital gain if the Holder's holding period with respect to the stock
is more than one year, and otherwise will be short-term capital gain. If,
however, the cash received has the effect of the distribution of a dividend, the
gain would be treated as a dividend to the extent of the Holder's ratable share
of CIC's accumulated earnings and profits. See "Possible Treatment of Cash as a
Dividend." The 0.25% of each holder's Merger Consideration that is deposited
into the Fees and Expenses Fund will be treated as cash and taxed accordingly.

         The aggregate tax basis of Airgas Common Stock received by a Holder
that exchanges its shares of CIC Common Stock for a combination of Airgas Common
Stock and cash pursuant to the Merger will be equal to the aggregate adjusted
tax basis of the shares of CIC Common Stock surrendered therefor, decreased by
the cash received and increased by any recognized gain (whether capital gain or
ordinary income). The holding period of such Airgas Common Stock will include
the holding period of the shares of CIC Common Stock surrendered therefor. If a
Holder has differing bases or holding periods in respect of its shares of CIC
Common Stock, it should consult its tax adviser prior to the exchange to
identify the particular shares of CIC Common Stock to be surrendered in the
exchange and the particular bases or holding periods of the particular shares of
Airgas Common Stock it receives in the exchange.

         Possible Treatment of Cash as a Dividend. In general, the determination
         ----------------------------------------
of whether the gain recognized in the exchange will be treated as capital gain
or dividend income depends upon whether and to what extent the exchange reduces
the Holder's deemed percentage stock ownership of Airgas. For purposes of this
determination, the Holder is treated as if it first exchanged all of its shares
of CIC Common Stock solely for Airgas Common Stock and then Airgas immediately
redeemed (the "Deemed Redemption") a portion of such Airgas Common Stock in
exchange for the cash the holder actually received. The gain recognized in the
exchange followed by a Deemed Redemption will be treated as capital gain if the
Deemed Redemption is (i) "substantially disproportionate" with respect to the
holder or (ii) "not essentially equivalent to a dividend."

         The Deemed Redemption, generally, will be "substantially
disproportionate" with respect to a Holder if the percentage described in (ii)
below is less than 80% of the percentage described in (i) below. Whether the
Deemed Redemption is "not essentially equivalent to a dividend" with respect to
a Holder will depend upon the Holder's particular circumstances. At a minimum,
however, in order for the Deemed Redemption to be "not essentially equivalent to
a dividend," the Deemed Redemption must result in a "meaningful reduction" in
the Holder's deemed percentage stock ownership of Airgas. In general, that
determination requires a comparison of (i) the percentage of the outstanding
stock of Airgas that the Holder is deemed actually and constructively to have
owned immediately before the Deemed Redemption and (ii) the percentage of the
outstanding stock of Airgas that is actually and constructively owned by the
Holder immediately after the Deemed Redemption. In applying the foregoing tests,
a stockholder is deemed to own stock owned and, in some cases, constructively
owned by certain family members, certain estates and trusts of which the Holder
is a beneficiary, certain affiliated entities, and stock subject to an option
actually or constructively owned by the Stockholder or such other persons. As
these rules are complex, each Holder that may be subject to these rules should
consult its tax adviser. The Internal

                                      33
<PAGE>
 
Revenue Service has ruled that a relatively minor reduction in the percentage
stock ownership of a minority stockholder in a publicly held corporation whose
relative stock interest is minimal and who exercises no control with respect to
corporate affairs is a "meaningful reduction." Accordingly, in most
circumstances, gain recognized by a Holder that exchanges its shares of CIC
Common Stock for a combination of Airgas Common Stock and cash generally will be
long-term capital gain or loss if the Holder's holding period with respect to
the stock is more than one year, and otherwise will be short-term capital gain.

         Backup Withholding. Unless a Holder complies with certain reporting or
         ------------------
certification procedures or is an "exempt recipient" (i.e., in general,
corporations and certain other entities), the Holder may be subject to
withholding tax of 31% with respect to any cash payments received pursuant to
the Merger. A foreign Holder should consult its tax adviser with respect to the
application of withholding rules to it with respect to any cash payments
received pursuant to the Merger.

         Federal Income Tax Information for CIC Optionholders. The assumption or
         ----------------------------------------------------
substitution of a compensatory stock option of CIC by Airgas should not
generally result in the recognition of gain or loss to the holder thereof.
Incentive stock options ("ISOs") of Airgas received in exchange for CIC ISOs
should be treated as incentive stock options for purposes of Section 422 of the
Code, provided no additional benefit is received by the optionholders in
connection with the assumption or substitution of the options by Airgas. If an
additional benefit is received, the assumed or substituted option will be
treated as a nonstatutory stock option.

         The optionee should not recognize any ordinary income for federal
income tax purposes upon the exercise of an ISO. Upon a sale of Airgas Common
Stock, the tax treatment to the optionee will depend primarily upon whether the
optionee has met certain holding period requirements at the time of sale. In
addition, as discussed below, the exercise of an ISO may subject the optionee to
alternative minimum tax liability in the year of exercise.

         If an optionee exercises an ISO and does not dispose of the shares
received within two years of the date of the grant of such option and within one
year after transfer of the shares to the optionee, whichever ends later, any
gain realized upon disposition will be treated as long-term capital gain, and
any loss will be long-term capital loss.

         If the optionee disposes of the shares either within two years after
the date an ISO is granted or within one year after an ISO was exercised, such
disposition will be treated as a disqualifying disposition and an amount equal
to the lesser of (1) the fair market value of the shares on the date of exercise
less the purchase price for said shares or (2) the amount realized on the
disposition less the purchase price for said shares, will be taxed as ordinary
income in the taxable year in which the disposition occurs. Any such ordinary
income will increase the optionee's tax basis for purposes of determining gain
or loss on the sale or exchange of such shares. The excess, if any, of the
amount realized upon disposition of shares over the basis of such shares will be
treated as short-term or long-term capital gain, as the case may be, and any
loss realized upon the disposition will be treated as a capital loss.

         The exercise of an ISO may subject an optionee to alternative minimum
tax liability in the year of exercise because the excess of the fair market
value of the shares at the time an ISO is exercised over the option price is an
adjustment in determining an optionee's alternative minimum taxable income for

                                      34
<PAGE>
 
such year. Consequently, an optionee may be obligated to pay alternative minimum
tax in the year the optionee exercises an ISO. An optionee who makes a
disqualifying disposition of shares acquired upon exercise of an ISO must still
treat such excess as an adjustment in determining alternative minimum taxable
income. In the case of a disqualifying disposition which occurs after the year
of exercise, an individual would be required to recognize alternative minimum
tax in the year of exercise and ordinary income in the year of such
disqualifying disposition in an amount determined under the rule described
above. In addition, an optionee's alternative minimum tax liability is affected
by the availability of a special credit, a basis adjustment and other complex
rules.

         If an optionee receives a nonstatutory stock option, upon the exercise
of such option the optionee will recognize ordinary income for federal income
tax purposes measured by the excess, if any, of the then fair market value of
the Airgas Common Stock at the date of exercise over the option exercise price.
Upon a sale of any Airgas Common Stock acquired pursuant to the exercise of a
nonstatutory stock option, the difference between the sales price and the
optionee's basis in the shares will be treated as a long-term capital gain or
loss if the optionee's holding period with respect to the stock is more than one
year, and otherwise will be short term capital gain or loss. The optionee's tax
basis for determination of gain or loss upon any subsequent disposition of
shares acquired upon the exercise of a nonstatutory stock option will be the
amount paid for such shares plus any ordinary income recognized as a result of
the exercise of such option.

         THE FOREGOING DISCUSSION IS ONLY A SUMMARY OF THE MORE SIGNIFICANT
EFFECTS OF THE U.S. FEDERAL INCOME TAX LAWS UPON THE MERGER CONSIDERATION TO BE
RECEIVED IN THE MERGER, AND THE AIRGAS OPTIONS AND AIRGAS COMMON STOCK ISSUABLE
UPON EXERCISE OF THE AIRGAS OPTIONS AND DOES NOT PURPORT TO BE COMPLETE.
REFERENCE SHOULD BE MADE TO THE APPLICABLE PROVISIONS OF THE CODE AND THE INCOME
TAX REGULATIONS PROMULGATED THEREUNDER. IN ADDITION, THIS SUMMARY DOES NOT
DISCUSS THE PROVISIONS OF THE INCOME TAX LAWS OF ANY STATE OR FOREIGN COUNTRY IN
WHICH AN OPTIONEE MAY RESIDE. EACH OPTIONEE SHOULD CONSULT WITH SUCH OPTIONEE'S
OWN ADVISER CONCERNING THE FEDERAL (AND ANY STATE OR LOCAL) INCOME TAX
CONSEQUENCES, INCLUDING THE APPLICABILITY OF ALTERNATIVE MINIMUM TAX TO THE
OPTIONEE'S CIRCUMSTANCES.

Accounting Treatment

         The Merger is to be accounted for under the purchase method of
accounting in accordance with generally accepted accounting principles, whereby
the purchase price will be allocated based on the fair value of the assets
acquired and the liabilities assumed. Such allocations will be based upon
valuations that have not been finalized. The excess of such purchase price over
the amounts so allocated will be recorded as goodwill. See "Unaudited Pro Forma
Financial Information."

Expenses of the Merger

         Airgas and CIC will pay their respective costs in connection with the
Merger. If for any reason the Merger is not consummated and the Merger Agreement
is terminated, each party shall bear the expenses incurred by it in connection
with the proposed Merger. Airgas estimates that the maximum amount of funds
required to pay the Cash Consideration will be approximately $18,405,000.       

Resales of Airgas Common Stock by Former CIC Shareholders

         Airgas Common Stock acquired by persons who may be deemed to be CIC
affiliates may be resold in transactions permitted by Rule 145 under the
Securities Act, pursuant to an effective registration statement under the
Securities Act or in transactions exempt from registration. Rule 145, as
currently in effect, imposes restrictions on the manner in which such affiliates
may make resales and also on the quantity of resales which such affiliates, and
others with whom they may act in concert, may make within any three-month
period.

         Persons who may be deemed to be affiliates of CIC include officers,
directors and certain of the larger holders of CIC's Common Stock. CIC
shareholders who are not deemed to be affiliates of CIC or Airgas may sell their
Airgas Common Stock without restriction.

Dissenters' Rights

         Each shareholder of CIC Common Stock is entitled to dissent from the
Merger and obtain payment of the Fair Value of his shares of CIC Common Stock
pursuant to Sections 607.1301, 607.1302 and 607.1320 of the FBCA, copies of
which are attached hereto as Appendix B. Any shareholder who does not timely and
completely comply with the provisions of the FBCA will be bound by the terms of
the Merger Agreement and will be entitled to receive Airgas Common Stock or
cash, or a combination thereof, as applicable, as provided in the Merger
Agreement.

         The term "Fair Value" means the value of shares of CIC Common Stock
as of the close of business on the day prior to the date on which the
shareholder vote authorizing the Merger is taken (the Special Meeting),
exclusive of any appreciation or depreciation in anticipation of the Merger
(unless exclusion would be inequitable). The Fair Value of the CIC Common Stock
may be more or less than the consideration that a holder of such stock would be
entitled to receive in the Merger.

         The following is a summary of the procedures to be followed by CIC
shareholders who wish to dissent from the Merger. It does not purport to be a
complete statement of the proceedings to be followed by CIC shareholders
desiring to exercise dissenters' rights of appraisal. In the event of a conflict
between this summary and the provisions of the FBCA, the FBCA shall prevail.
Because exercise of such rights requires strict adherence to the statutory
provisions referred to in this summary, each CIC shareholder who may desire to
exercise such rights should adhere to the provisions of such laws and consult
with such holder's legal advisers.

         (1) Pursuant to Section 607.1320 of the FBCA, any shareholder who
wishes to assert dissenters' rights (i) must deliver to CIC prior to the
shareholders' vote on the Merger written notice of his intent to demand payment
of the Fair Value for his shares if the Merger is effectuated (a "Notice of


                                      36
<PAGE>
 
Intent"), and (ii) must not vote his shares in favor of the Merger. A proxy or
vote against the Merger does not constitute a Notice of Intent. A shareholder
may dissent as to less than all the shares registered in his name. If he does
so, the shares as to which he dissents and the other shares will be treated as
though they were registered in the names of different shareholders.

         (2) Within ten days of the shareholder approval of the Merger, the
Airgas Subsidiary, as the surviving corporation in the Merger (the "Surviving
Corporation"), will give written notice of such approval to each shareholder who
timely filed a Notice of Intent.

         (3) Within twenty days after the giving of such notice to such
shareholders, each shareholder electing to assert dissenters' rights shall file
with the Surviving Corporation a notice of such election stating his name and
address, the number, classes and series of shares as to which he dissents, and a
demand for payment of the Fair Value of his shares (a "Notice of Election"). Any
shareholder filing a Notice of Election is required to deposit his share
certificates with the Surviving Corporation simultaneously with filing the
Notice of Election. Once a shareholder has filed a Notice of Election he is no
longer entitled to vote or exercise any of the other rights of a shareholder.
The Notice of Election may be withdrawn in writing by the shareholder at any
time before the Surviving Corporation makes the offer of payment described
below; once the offer of payment is made, a Notice of Election to dissent may
not be withdrawn unless the Surviving Corporation consents.

         (4) Within ten days after the expiration of the period in which
shareholders electing to assert dissenters' rights must file the Notice of
Election, or within ten days after the Merger is effected, whichever is later,
the Surviving Corporation will make a written offer to pay each dissenter a
specified price deemed by the Surviving Corporation to be the Fair Value of his
shares. The offer of payment will be accompanied by a recent balance sheet of
CIC and a profit and loss statement covering the twelve-month period ending as
of such balance sheet.

         (5) If the dissenter accepts the Surviving Corporation's offer within
30 days of its making, the Surviving Corporation shall pay him for his shares
within 90 days after the making of the offer or the consummation of the Merger
(whichever is later), and he shall cease to have any interest in those shares
thereafter.

         (6) If the Surviving Corporation fails to make a timely offer, or if it
makes the offer and the dissenting shareholder fails to accept the offer within
30 days thereafter, then the Surviving Corporation, within 30 days after receipt
of a written demand from any dissenting shareholder given within 60 days after
the Merger, shall, or at its election at any time within such 60 days, may file
an action in any court of competent jurisdiction in Broward County, Florida,
requesting that the Fair Value of the shares be determined by the court. If the
Surviving Corporation fails to institute such a proceeding, then any dissenting
shareholder may file such an action in the name of the Surviving Corporation.
Each shareholder whose demand remains unsettled shall be made a party to the
proceeding and shall be entitled to judgment for the amount which the court
finds to be the Fair Value of his shares. The court may appoint one or more
appraisers to receive evidence and recommend a decision on the question of Fair
Value.

         (7) The court shall determine all costs of the proceeding, including
the compensation of appraisers appointed by the court, but not including fees
and expenses of attorneys and experts of the


                                      37
<PAGE>
 
parties. Such costs shall be assessed against the Surviving Corporation, except
that the court may assess the costs against all or some of the dissenters to
whom the Surviving Corporation made an offer of payment, in amounts the court
finds equitable, to the extent the court finds any dissenters acted arbitrarily,
vexatiously or not in good faith in failing to accept the Surviving
Corporation's offer. If the Fair Value of the shares is determined to be
materially higher than the amount the Surviving Corporation offered to pay or if
no offer was made, the court may award any dissenting shareholder such sum that
the court determines is reasonable compensation to any attorney or expert
employed by the dissenting shareholder in the proceeding.

         (8) Notwithstanding the foregoing, a shareholder will not be entitled
to be paid the Fair Value of his shares, and will have all his rights as a
shareholder reinstated as of the date of filing of his Notice of Election,
including any rights to intervening distributions or dividends and to payment of
the consideration that would otherwise be payable to such shareholder as
provided in the Merger Agreement, if (i) his Notice of Election is withdrawn as
provided above, (ii) the Merger is abandoned, rescinded or the shareholders
revoke the authority to effect it, (iii) no petition for a determination of Fair
Value by a court is made within 60 days after the Merger, or (iv) the court
determines that such shareholder is not entitled to dissenters' rights.

         Airgas shareholders will not have dissenters' rights in connection with
the Merger.

Comparison of Shareholders' Rights

         The rights of Airgas stockholders are governed by Airgas' Amended and
Restated Certificate of Incorporation (the "Airgas Certificate"), Airgas'
Bylaws, and by the DGCL. The rights of CIC shareholders are currently governed
by the CIC Articles of Incorporation, CIC's Bylaws, and by the FBCA. After the
Merger, the rights of CIC shareholders who receive Airgas Common Stock in the
Merger will thereafter be governed by the Airgas Certificate, Airgas' Bylaws,
and by the DGCL. The following discussion describes the material differences in
the rights of stockholders of Airgas and shareholders of CIC.

         Board of Directors; Removal; Filling Vacancies
         ----------------------------------------------

         Airgas. Article III, Section 1 of the Airgas Bylaws provides that the
         ------
number of directors which shall comprise the full Board of Directors of the
corporation shall consist of no less than seven and no more than thirteen
members, as shall be fixed by resolution of the Board of Directors. There are
currently nine members on the Airgas Board of Directors. The Airgas Bylaws,
pursuant to Article III, Section 4, provide that the entire Board of Directors
or any individual Director may be removed without cause from office by the
holders of 67% of the combined voting power of the then outstanding shares
entitled to vote, subject to any rights of holders of any preferred stock.
Vacancies in the Board of Directors may be filled by a majority of the remaining
Directors in office, though less than a quorum, or by a sole remaining Director.


         CIC. Article VII of CIC's Articles of Incorporation requires CIC to
         ---
have not less than three directors and to have an odd number of directors.
Article II, Section 1 of CIC's Bylaws fixes the number of directors at seven,
one of which must be resident of the State of Florida. Article III of CIC's
Articles


                                      38
<PAGE>
 
of Incorporation stipulates that the holders of Class B Common are entitled to
elect a majority of the Board of Directors. Any director may be removed by the
shareholders at any time, with or without cause. Vacancies on CIC's Board may be
filled, pursuant to Section 9 of Article II of CIC's Bylaws, by a majority of
the directors then in office, and such chosen director shall hold office until
his successor is duly elected or qualified.

         Action by Written Consent; Special Meetings
         -------------------------------------------

         Airgas. The Airgas Certificate provides that Airgas stockholders may
         ------
not act by written consent without a stockholders' meeting for which notice of
such meeting has been provided to Airgas stockholders. Special meetings of
Airgas stockholders may be called at any time and for any purposes but only by
the Board of Directors pursuant to a resolution approved by the Board or
pursuant to the request of holders of 33% of the combined voting power of the
then outstanding shares entitled to vote.

         CIC. Action by the shareholders of CIC may only be taken at a meeting
         ---
of the shareholders. Section 3 of Article I of the CIC Bylaws provides that
special meetings of the shareholders may be called for any purpose by a majority
of the Board of Directors or, if requested in writing, by shareholders holding 
at least 50% of the outstanding capital stock.

         Vote Required for Certain Transactions
         --------------------------------------

         DGCL. Under the DGCL, a merger, consolidation or sale of all or
         ----
substantially all of a corporation's assets generally must be approved by the
stockholders of each constituent corporation by the affirmative vote of the
holders of a majority of the outstanding shares entitled to vote on the
transaction. Stockholders of the surviving corporation need not approve the
merger if: (i) the corporation's certificate of incorporation will not be
amended as a result of the merger; (ii) each share of the corporation's stock
outstanding immediately prior to the effective date of the merger will be an
identical outstanding or treasury share of the corporation after the effective
date of the merger; and (iii) either no shares of the corporation's common stock
and no securities convertible into such stock will be issued pursuant to the
merger or the authorized unissued shares or treasury shares of the corporation's
common stock to be issued pursuant to the merger do not exceed 20% of the shares
of the corporation's common stock outstanding immediately prior to the effective
date of the merger.

         FBCA. In connection with the approval of proposed mergers and share
         ----
exchanges, the FBCA generally requires the affirmative vote of a majority of all
votes entitled to be cast on the plan for such transaction by all shares
entitled to vote on the plan, voting as a single group, and the affirmative vote
of a majority of the votes entitled to be cast by holders of shares of each
voting group entitled to vote as a group under the corporation's articles of
incorporation. Unless the articles of incorporation or the Board of Directors
requires a greater vote or a vote by voting groups, the sale of all or
substantially all of the assets of a corporation must be approved by the
affirmative vote of a majority of all the votes entitled to be cast on the
matter. Under the FBCA, stockholders of the surviving corporation need not
approve a merger if: (i) the articles of incorporation of the corporation will
not differ from its articles before the merger (except for certain amendments
permitted under the FBCA without shareholder approval); (ii) each share of stock
of the corporation outstanding immediately before the effective date of the
merger is to be an identical outstanding share immediately after the merger; and
(iii) the number

                                      39
<PAGE>
 
and kind of shares outstanding immediately after the merger; plus the number and
kind of shares issuable as a result of the merger and by conversion of
securities issued pursuant to the merger or the exercise of rights and warrants
issued pursuant to the merger, will not exceed the total number and kind of
shares of the surviving corporation authorized by its articles of incorporation
immediately before the merger.

         Both the DGCL and the FCBA permit corporations to require higher votes
for approval of the transactions described above in their articles of
incorporation or bylaws.

         Business Combinations
         ---------------------

         Airgas. The Airgas Certificate provides that any "Business Combination"
         ------
(hereinafter referred to as an "Airgas Business Combination") involving Airgas
and a person who beneficially owns, directly or indirectly, 20% or more of
Airgas' capital stock (an "Airgas Interested Stockholder") entitled to vote
generally for the election of directors ("Voting Stock") must be approved by the
affirmative vote of not less than sixty-seven percent (67%) of the Voting Stock
(the "Airgas Voting Requirement"). The Airgas Voting Requirement does not apply
if the majority of the Disinterested Directors (defined as a member of the Board
of Directors of Airgas, other than the Airgas Interested Stockholder, who was a
director prior to the time the Interested Stockholder became an Interested
Stockholder, or any director who was recommended for election by the
Disinterested Directors) approve the Airgas Business Combination or certain
conditions regarding price and procedure have been satisfied.

         CIC. The CIC Certificate and its Bylaws do not provide for a "Business
         ---
Combination" provision.

         DGCL. Section 203 of the DGCL, which is applicable to Airgas as a
         ----
Delaware corporation, provides that, subject to certain exceptions specified
therein, a corporation shall not engage in any business combination with any
"interested stockholder" for a three-year period following the date that such
stockholder becomes an interested stockholder unless (i) prior to such date, the
board of directors of the corporation approved either the business combination
or the transaction which resulted in the stockholder becoming an interested
stockholder; (ii) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding shares held by directors who are also officers
and employee stock purchase plans in which employee participants do not have the
right to determine confidentially whether plan shares will be tendered in a
tender or exchange offer); or (iii) on or subsequent to such date, the business
combination is approved by the board of directors of the corporation and by the
affirmative vote at an annual or special meeting, and not by written consent, of
at least 66 2/3% of the outstanding voting stock which is not owned by the
interested stockholder. Except as specified in Section 203 of the DGCL, an
interested stockholder is defined to include (a) any person that is the owner of
15% or more of the outstanding voting stock of the corporation or is an
affiliate or associate of the corporation and was the owner of 15% or more of
the outstanding voting stock of the corporation, at any time within three years
immediately prior to the relevant date and (b) the affiliates and associates of
any such person. Under certain circumstances, Section 203 of the DGCL may make
it more difficult for a person who would be an "interested stockholder" to
effect various business combinations with a corporation for a three-year period,
although the corporation's certificate of incorporation or stockholders may
elect to exclude a corporation from the restrictions imposed thereunder.


                                      40
<PAGE>
 
         FBCA. Section 607.0901 of the FBCA, informally known as the "Affiliated
         ----
Transactions Statute," provides that the approval of the holders of two-thirds
(2/3) of the voting shares of a company, other than the shares owned by an
Interested Shareholder (as defined below), would be required to effectuate
certain transactions, including without limitation a merger, consolidation, sale
of assets, sale of shares, liquidation or dissolution of the corporation, and
reclassification of securities involving a corporation and an Interested
Shareholder (an "Affiliated Transaction"). An "Interested Shareholder" is
defined as the beneficial owner of 10% of the voting shares outstanding. The
foregoing special voting requirement is in addition to the vote required by any
other provision of the FBCA or a corporation's articles of incorporation.

         The special voting requirement does not apply in any of the following
four circumstances: (i) the Affiliated Transaction is approved by a majority of
the corporation's disinterested directors; (ii) the Interested Shareholder has
owned 80% of the corporation's voting stock for five years: (iii) the Interested
Shareholder owns more than 90% of the corporation's voting shares; (iv) the
corporation has not had more than 300 shareholders of record at any time during
the three years preceding the announcement of the event; (v) the corporation is
an investment company registered under the Investment Company Act of 1940; or
(vi) all of the following conditions are met: (a) the cash and fair value of
other consideration to be paid per share to all holders of voting shares equals
the highest per share price calculated pursuant to various methods set forth in
Section 607.0901; (b) the consideration to be paid in the Affiliated Transaction
is in the same form as previously paid by the Interested Shareholder; (c) during
the portion of the three years proceeding the announcement date that the
Interested Shareholder has been an Interested Shareholder, except as approved by
a majority of the disinterested directors, there shall have been no default in
payment of preferred stock dividends, no decrease in annual stock dividends, no
increase in annual dividends necessary to reflect any transaction which has the
effect of reducing outstanding stock, no increase in the voting shares owned by
the Interested Shareholder, and no benefit to the Interested Shareholder from
loans, guaranties or other financial assistance or tax advantages provided by
the corporation. This requirement is not applicable to the Merger because, as
provided by Section 607.0901, a majority of CIC's "disinterested" directors have
approved the Merger, the Merger Agreement and the transactions contemplated
thereby.

         Section 607.0902 of the FBCA, known informally as the "Florida Control
Share Acquisition Statute," provides that the voting rights to be accorded
Control Shares (as defined below) of a Florida corporation that has (i) 100 or
more shareholders; (ii) its principal place of business, its principal office or
substantial assets in Florida, and (iii) either (a) more than 10% of its
shareholders residing in Florida, (b) more than 10% of its shares owned by
Florida residents or (c) 1,000 shareholders residing in Florida, must be
approved by a majority of each class of voting securities of the corporation
before the Control Shares will be granted any voting rights. "Control Shares"
are defined in the FBCA to be shares of the issuing corporation owned by such
person, that would entitle such person to exercise, either directly or
indirectly, voting power within any of the following ranges; (1) 20% or more but
less than 33% of all voting power of the corporation's voting securities, (2)
33% or more but less than a majority of all voting power of the corporation's
voting securities or (3) a majority or more of all of the voting power of the
corporation's voting securities. A "Control Share Acquisition" is defined in the
FBCA as an acquisition, either directly or indirectly, by any person of
ownership of, or the power to direct the exercise of voting power with respect
to, outstanding Control Shares. Section 607.0902 also indicates that, if
provided in the articles of incorporation or bylaws of a corporation, Control
Shares may be redeemed by the corporation for fair value in certain
circumstances. Finally, unless otherwise provided in a corporation's

                                      41
<PAGE>
 
articles of incorporation or bylaws prior to a Control Share Acquisition, in the
event Control Shares are accorded full voting rights and the acquiring person
has acquired Control Shares with a majority or more of all voting power, all
shareholders shall have dissenters' rights. This requirement is not applicable
to the Merger because, as provided by Section 607.0902, (a) the transaction was
unanimously approved by the CIC Board, and (b) the transaction will be
consummated pursuant to a statutory merger and CIC is a party to the Merger
Agreement.

         Amendment of Certificate of Incorporation, Articles of Incorporation
         -------------------------------------------------------------------- 
and Bylaws
- ----------       

         Airgas. Articles 5 and 6 of the Airgas Certificate provide that the
         ------
amendment or repeal of such articles shall require the affirmative vote of the
holders of at least 67% of the voting power of the outstanding shares of capital
stock entitled to vote generally for directors. In addition, so long as any
shares of Non-Voting Preferred Stock are outstanding, if an amendment would
change the rights and preferences of the Non-Voting Preferred Stock, Article 4
may not be amended without the approval of the holders of a majority of the
outstanding shares of Non-Voting Preferred Stock voting as a class. Article 8 of
the Airgas Certificate provides that, except as described above, the Airgas
Certificate may be amended, altered or repealed as authorized by the DGCL and in
the Airgas Certificate. Pursuant to the DGCL, Airgas' Certificate may be amended
if the Board of Directors adopts a resolution setting forth the proposed
amendment, declares its advisability and calls a stockholders' meeting for
consideration of such amendment. At the meeting, the amendment must be approved
by a majority of the outstanding shares entitled to vote.

         Article IX of Airgas' Bylaws provides that the Bylaws may be amended or
repealed by the vote of holders of a majority of the outstanding shares entitled
to vote, except that amendment of Article III (relating to Directors) requires
the affirmative vote of the holders of 67% of the voting power of all
outstanding shares entitled to vote generally in the election of directors.
Article IX also provides that, subject to the DGCL and the Airgas Certificate,
the Board of Directors may adopt, amend or repeal the Bylaws.

         CIC. Pursuant to the FBCA, a majority of the shareholders entitled to
         ---
vote must approve amendments to the articles of incorporation, except for
certain types of amendments that the corporation's board of directors may adopt
without shareholder approval, unless precluded from doing so in the
corporation's articles of incorporation. Article X of CIC's Articles of
Incorporation requires each amendment to the Articles of Incorporation to be
approved by the Board of Directors and by a majority of the stock entitled to
vote thereon, unless all directors and shareholders sign a statement indicating
their intention that a certain amendment be made. Article VIII of the CIC Bylaws
provides that the CIC Bylaws may be amended, altered, repealed or added to by
the affirmative vote of the shareholders representing two-thirds of the capital
stock.

         Indemnification
         ---------------

         Airgas. Article VII of Airgas' Bylaws provide indemnification by Airgas
         ------
to the full extent permitted by law, under the DGCL, to any director or officer
of Airgas who is made or threatened to be made a party to any action or
proceeding by reason of their position. Airgas' Certificate and Bylaws provide
for the limitation of the liability of its directors, in accordance with the
DGCL, to Airgas or its

                                      42
<PAGE>
 
stockholders for monetary damages for breach of fiduciary duty except where such
exemption is not permitted under the DGCL.

         CIC. CIC's Bylaws do not provide for indemnification by CIC of CIC's
         ---
directors or officers. However, under Section 607.0850 of the FBCA, a director,
officer, employee or agent of CIC is entitled to indemnification if he has been
successful in defense of any proceeding made against him by reason of his
position except where such indemnification is not permitted by the FBCA. Before
such indemnification can be paid, it must be determined to be permissible by a
corporation's Board of Directors, a committee of the Board composed of two or
more directors not a party to the proceeding, by independent legal counsel or by
the shareholders. The party seeking indemnification may apply to the court
conducting the proceeding, the circuit court or a court of competent
jurisdiction for indemnification or advancement of expenses or both if the
corporation fails to so provide. CIC may not indemnify its directors and
officers with respect to any action, suit, or proceeding by or in the right of
CIC where the person has been adjudged to be liable for negligence or misconduct
in the performance of his duty to CIC unless indemnity is deemed proper by the
court in which the action or suit was brought. Subject to limited exceptions,
section 607.0831 of the FBCA exonerates directors from personal liability for
monetary damages for any vote, decision, statement or failure to act, regarding
corporate policy or management.

         Other Items
         -----------

         Airgas. Article 7 of the Airgas Certificate provides for the prevention
         ------
of the payment of greenmail by requiring that the holders of at least a majority
of the combined voting power of the Airgas Voting Stock, voting as a single
class, approve any direct or indirect purchase or other acquisition by Airgas of
any voting stock of any class from any Airgas Interested Stockholder. Airgas has
adopted a preferred stock purchase rights plan. See "Airgas - Description of
Capital Stock - Rights Agreement."

         CIC.  CIC has not adopted a stock purchase rights plan.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION


The following Unaudited Pro Forma Combined Condensed Balance Sheet at December
31, 1996, and the Unaudited Pro Forma Combined Condensed Statements of Earnings
for the year ended March 31, 1996 and the nine months ended December 31, 1996
combine information for Airgas and CIC and include unaudited pro forma
adjustments as described in the accompanying notes. The Unaudited Pro Forma
Combined Condensed Statements of Earnings give effect to the proposed Merger as
if it had occurred at April 1, 1995 for the year ended March 31, 1996 and April
1, 1996 for the nine months ended December 31, 1996. The Unaudited Pro Forma
Combined Condensed Balance Sheet gives effect to the Merger as if it had
occurred at December 31, 1996. The Pro Forma Combined Condensed Financial
Statements are based on historical financial statements of Airgas and CIC,
giving effect to the Merger, and applying the purchase method of accounting and
the assumptions and adjustments as discussed in the accompanying notes to the
Pro Forma Combined Condensed Financial Statements. These Pro Forma Combined
Condensed Financial Statements are based upon (i) for Airgas: the audited
consolidated financial statements as of March 31, 1996 and for the year then
ended and the unaudited consolidated financial statements as of December 31,
1996 and for the nine months then ended, and (ii) for CIC: the audited financial
statements as of December 31, 1995 and for the year then ended and the unaudited
financial statements as of September 30, 1996 and for the nine months then
ended. These statements are based, and should be read in conjunction with, the
historical financial statements of Airgas and CIC which are included elsewhere
in this Proxy Statement. The unaudited pro forma adjustments described in the
accompanying notes are based upon preliminary estimates and certain assumptions
that Airgas' management believes are reasonable in such circumstances. The pro
forma data are presented for information purposes only and are not necessarily
indicative of the actual operating results or financial position that would have
occurred had the Merger been consummated at the dates indicated, nor are they
necessarily indicative of future operating results or financial position.

                    COMBINED CONDENSED FINANCIAL STATEMENTS

(1)  The cost of the acquisition of CIC Common Stock is assumed to be
     approximately $59.5 million. Assuming that (a) 60% of the value of the
     Class A Common is converted into Airgas Common Stock, and 40% of the value
     of Class A Common is converted to cash and (b) 55% of the value of Class B
     Common is converted to Airgas Common Stock and 45% of the value of Class B
     Common is converted to cash, the components of the total purchase price are
     (i) $24.3 million of Airgas Common Stock exchanged for 60% of the value of
     Class A Common and 55% of the value of Class B Common, (ii) $16.6 million
     of cash exchanged for 40% of the aggregate value of Class A Common and 45%
     of the value of Class B Common, (iii) $2.1 million of additional paid-in
     capital from 72,000 CIC stock options assumed by Airgas and (iv) the
     assumption of CIC debt and other liabilities which total $16.5 million.

     For purposes of these Pro Forma Combined Condensed Financial Statements, it
     is assumed that 1,619,000 shares of Airgas Common Stock will be issued to
     CIC shareholders for the value of CIC Common Stock, and 138,000 shares will
     be issued for the CIC stock options assumed by Airgas. The actual cash and
     Airgas Common Stock will be determined in accordance with the Merger
     Agreement between Airgas and CIC, but is not expected to be materially
     different from the assumption made here. Assuming 90% of the value of the
     Class A Common and 55% of the Class B Common are converted into Airgas
     Common Stock, 2,334,000 shares of Airgas Common Stock will be issued to CIC
     shareholders.

     Pro forma adjustments to the Combined Condensed Balance Sheet include (a)
     eliminating the equity accounts of CIC, (b) recording additional equity for
     the issuance of Airgas Common Stock and assumption of the CIC stock
     options, (c) recording of the debt borrowed and the cash decrease resulting
     from funding the cash portion of the purchase price, (d) recording the
     assumed payables and other accrued expenses of CIC, (e) adjusting the CIC
     fixed assets to their fair market values and (f) establishing a value for
     goodwill for the purchase price in excess of the fair value of the assets
     acquired.

     The pro forma adjustments to the Combined Condensed Balance Sheet assume
     that the merger occurred on December 31, 1996. For the purposes of these
     Pro Forma Combined Condensed Financial Statements, the fair market values
     of the fixed assets acquired are estimated. The actual fair market values
     will be determined by independent appraisers and may be more or less than
     the costs estimated here. Subsequent to the acquisition, Airgas will apply
     the appraised values and more fully evaluate the assets acquired, and, as a
     result, the allocation of purchase price may change.

(2)  A reconciliation of the pro forma adjustment to long-term debt is as
     follows, assuming 40% of the value of the Class A Common and 45% of the
     value of Class B Common are converted into cash:

(3)      A reconciliation of the pro forma adjustment to stockholders' equity is

         Stock respectively, based on an assumed $15.00 Average Airgas Price:

(4)      Depreciation and amortization expenses have been increased to reflect
         the purchase accounting adjustments related to the acquired fixed
         assets and goodwill. Goodwill is amortized over 40 years.

(5)           Interest expense has been adjusted to reflect the debt incurred in
              financing the business acquisition at Airgas' effective interest
              rate.

(6)           Income taxes have been adjusted to reflect Airgas' effective tax
              rate.

(7)           Pro forma per share data is calculated using the pro forma net
              earnings divided by the pro forma weighted average shares which
              include (a) 1,619,000 shares of Airgas Common Stock issued to CIC
              shareholders and (b) 138,000 shares from the exercise of the right
              per the Merger Agreement to convert all CIC options to Airgas
              Common Stock.  The calculation of the pro forma shares issued
              assume 60% of the value of the Class A Common and 55% of the Class
              B Common are converted into Airgas Common Stock, at an Average
              Airgas Price of $15.00 per share.  Earnings per share amounts were
              determined using the treasury stock method.  The treasury stock
              method assumes the exercise of all dilutive outstanding options
              and the use of the aggregate proceeds therefrom to acquire
              outstanding Airgas Common Stock.

Management's Discussion and Analysis of Financial
   Condition and Results of Operations

Recent Developments
    
         On April 14, 1997, Airgas announced that its results for the fourth 
quarter of its fiscal year ended March 31, 1997 will include a non-recurring 
charge associated with the damages resulting from the previously announced 
fraudulent breach of a contract by a third-party supplier, a write-down related
to two non-core, product-line businesses, and a loss related to the sale of a
Canadian medical home-care business. In addition, although Airgas expects cash
flow growth for the quarter, it anticipates that reported earnings for the
quarter, exclusive of these special charges, will likely be below analysts'
estimates due to expenses associated with Airgas' investments in new branches,
ADI, and its joint venture with National Welders Supply, as well as higher-than-
expected costs of consolidating distribution businesses acquired in the
Southeast over the past 24 months.     

         In connection with the fraudulent breach of contract by a third-party 
supplier of refrigerant gas which Airgas reported on December 23, 1996, Airgas 
intends to take a non-recurring pre-tax charge of approximately $26 million 
(approximately $17 million after-tax). This includes approximately $23 million 
for payments made to a third-party supplier and approximately $3 million in 
costs associated with Airgas' investigation into the matter and legal action 
taken by Airgas against the supplier and other parties. Airgas expects the loss 
from the fraudulent breach of contract to be partially offset by insurance 
claims along with cash and inventories expected to be recovered in litigation.

         Airgas will also take a pre-tax, non-cash charge of approximately $5 
million (approximately $3 million after-tax) related to the write-down of 
certain machinery and equipment, goodwill and other intangible assets of two 
non-core, product-line businesses. In addition, Airgas has recognized a $700,000
after-tax loss on the sale of medical home-care business in Ontario.

         Earnings per share, excluding the refrigerant and other charges and the
loss associated with the sale of the Ontario medical home-care business, are 
expected to be slightly below the $.17 per share reported in the fourth quarter 
of Airgas' 1996 fiscal year, for the reasons discussed above. Airgas anticipates
that the expenses associated with investments in information systems, logistics
and facilities enhancements for ADI will have a dilutive effect on earnings in 
fiscal 1998, but that such expenses will be offset by growth in the distribution
segment.

Financial Review - Overview - Nine Months Ended December 31, 1996

         Airgas' financial results for the nine months ended December 31, 1996
reflect growth compared with the comparable period last year. Net sales of $850
million, net earnings of $33.4 million and earnings per share of $.49 represent
increases over the prior period of 41%, 17% and 14%, respectively. Net sales
increased during the nine months compared to the prior period primarily as a
result of the acquisition of 58 distribution companies since April 1, 1995 and
an increase in same-store distribution sales of approximately 4%. The increase
in net earnings was primarily due to an increase in gross profits from higher
same-store distribution sales. Offsetting Airgas' earnings growth was dilution
associated with recent distribution acquisitions start-up, costs of new
distribution branches, Airgas' 45% joint venture investment in National Welders
Supply, Inc. ("National Welders"), and the start-up of ADI.

         Airgas' growth strategy through acquisitions continued through the
nine-month period. During the current fiscal year, Airgas has acquired
industrial gas distributors with annual sales of approximately $90 million. In
addition, Airgas formed a new segment, ADI, through two acquisitions, IPCO
Safety Products Company ("IPCO") and Rutland Tool & Supply Co., Inc.
("Rutland"), which have aggregate annual sales of approximately $120 million.

         On October 29, 1996, Airgas announced that it had signed a letter of
intent to acquire CIC, the fourth largest producer of carbon dioxide in the
United States, in a merger scheduled for completion during the first quarter of
fiscal 1998. CIC will be merged into a newly-formed subsidiary of Airgas in
exchange for a combination of Airgas' Common Stock and cash. In December 1996,
Airgas acquired Shell Land & Energy Company's interest in unitized leases
producing carbon dioxide, including Shell's 183 mile pipeline (the "Jackson
Dome" properties).

         Airgas intends to continue to grow through acquisitions while exploring
ways to leverage its broad geographic presence by selling additional products
and services to existing customers through its network of more than 600
distribution locations in 41 states, Canada and Mexico. Recent product line
additions have included returnable containers, specialty gases and additional
hardgoods (such as industrial supplies, safety products and coatings). Airgas
believes the selective addition of complementary products will enable it to
better serve its diverse, expanding customer base.

                                       51

         After tax cash flow (net earnings plus depreciation, amortization and
deferred income taxes) increased 22% to $86.4 million compared to $71.0 million
in the comparable nine-month period in the prior year. After tax cash flow per
share increased by 19% to $1.27 from $1.08 for the comparable nine-month period
last year. After tax cash flow is an important measurement of Airgas' ability to
repay debt through operations and provides Airgas with the ability to pursue
investment alternatives such as acquisitions and the repurchase of Airgas'
Common Stock.

         In a separate matter, as announced on December 23, 1996, Airgas was the
victim of a fraudulent breach of contract by a third party supplier related to
purchases of refrigerant R-12. Immediately upon discovering the fraud, Airgas
launched an intense effort to recover funds paid to the supplier and/or recover
product.

         Based on limited information currently available, Airgas is unable to
quantify the probable amount of the loss or recovery which may be associated
with the fraud. Airgas believes the maximum pre-tax loss, including associated
costs of the investigation and before considering any recoveries, will not
exceed $23 million, however, the minimum estimate is immaterial. At December 31,
1996, prepaid and other current assets includes $23.7 million of costs
associated with the fraud. Airgas believes there will be recoveries of assets
related to the fraud, including cash in bank accounts frozen under restraining
orders, recovery of product paid for and not delivered, net assets of the
refrigerant supplier which breached the contract and insurance proceeds under
Airgas' and the refrigerant supplier's policies. The aggregate recovery amount,
and the timing of recording various portions thereof, is subject to change, even
in the near term, as additional assets are identified, additional claims are
asserted or the market value of restrained assets fluctuates. Airgas will
continue to vigorously pursue all possible sources of recovery. Airgas
anticipates that it will record a charge to earnings during the fourth quarter
ending March 31, 1997, pending a full investigation of the facts and information
pertaining to the loss and potential remedies. On February 12, 1997, Airgas
filed a complaint seeking damages with respect to such loss. See "---
Litigation."

</TABLE> 

         For the nine months ended December 31, 1996, Distribution sales
increased approximately $150 million resulting from the acquisition of 58
distributors since April 1, 1995 and approximately $29 million from same-store
sales growth. Airgas estimates that had all acquisitions during the nine months
ended December 31, 1996 been consummated on April 1, 1996, Distribution sales
for 1996 would have

                                       52
<PAGE>
 
been approximately $27 million higher.  The increase in same-store Distribution
sales of approximately 4% was a result of growth in all three product groups:
gases, hardgoods and rent. The growth was attributable to strong sales of lower
margin hardgoods combined with selective price increases, Airgas' gas sales
initiatives related to small bulk and specialty gases, and continued growth in
rental income. Airgas believes its same-store sales growth is slightly
understated since it does not reflect Airgas' decision to cease unprofitable
sales to certain customers and other sales lost during acquisition consolidation
and integration activity. Airgas 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
Airgas' ability to expand markets for new and existing products and to increase
prices. Management believes Airgas' broad customer base and geographic diversity
help to reduce the adverse effects of an economic downturn on Airgas.

         Sales related to Airgas' ADI segment increased approximately 14% during
the nine months ended December 31, 1996 compared to historical sales results of
the prior year.

         Sales for Airgas' Manufacturing segment increased 11% during the nine
months ended December 31, 1996 as a result of the acquisition of the Jackson
Dome properties, increased sales of composite electrode paste and export sales
of calcined coal.

         The increase in Distribution gross profit of approximately $82 million
compared to the prior period resulted from acquisitions which contributed
approximately $67 million and from same-store gross profit growth of
approximately $15 million. The same-store gross profit growth is attributable to
expansion of gross margins through selective price increases and better buying
through national purchasing programs combined with increased sales of lower
margin hardgoods, increased sales of gases related to Airgas' small bulk and
specialty gases programs and growth in cylinder and other equipment rental
income. Compared to the prior year, Airgas' distribution gross margin of 49.7%
is down 130 basis points primarily due to industrial gas distribution
acquisitions which have an average gross margin of approximately 45%, and sales
of lower margin hardgoods.

         Selling, distribution and administrative expenses as a percentage of
gross profits remained unchanged at 67% compared to the prior year. Operating
costs associated with the consolidation and integration of acquisitions,
start-up of new distribution branches and start-up of ADI have been partially
offset by lower business insurance costs as a result of improved loss experience
rates and claims management and an insurance rebate. Until such acquisitions and
start-up activity is completed, Airgas expects that it will continue to incur
additional operating expenses.

         Operating income increased 28% during the nine months ended December
31, 1996 compared to the prior year:

         The Distribution operating income margin decreased 50 basis points to
10.3% compared to the same period in the prior year. The decrease was primarily
the result of recent industrial gas distribution acquisitions which have
operating margins averaging around 8%. Subject to the effects of future
acquisitions and the economy, Airgas believes that its distribution operating
income margin should improve as acquisitions are integrated.

         The operating income margin related to the ADI segment was 3.3%. Airgas
believes that its ADI operating income margin will improve as sales programs are
developed and implemented and upon the realization of the cost savings related
to more efficient warehousing and shipping.

         Manufacturing operating income increased $518 thousand compared to the
prior year primarily as a result of the acquisition of the Jackson Dome
properties, a strong demand for carbon products offset by a shift in sales more
towards lower margin exports of calcined coal versus domestic coal sales and
slightly lower nitrous oxide sales.

         Interest expense, net, increased $10.7 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, 1995 and interest costs associated with Airgas' investment in National
Welders Supply, offset by slightly lower interest rates. As discussed in
"Liquidity and Capital Resources" below, Airgas has hedged floating interest
rates under certain borrowings with interest rate swap agreements.

         Income tax expense represented 41.7% of pre-tax earnings in the nine
months ended December 31, 1996 compared to 42.3% in the prior year. The decrease
in the effective income tax rate was a result of state tax planning strategies
which were implemented late in fiscal 1996, offset by an increase in the
effective rate for non-deductible goodwill from recent acquisitions.

Financial Review - Overview - 1996 Fiscal Year Ended March 31, 1996

         Airgas' financial results for the year ended March 31, 1996 reflect
substantial growth compared to 1995. Net sales of $838 million, net earnings of
$39.7 million and earnings per share of $.60 represent increases over 1995 of
22%, 26% and 25%, respectively. Airgas also finished 1996 with a record year for
acquisitions by completing the acquisition of 42 distributors with aggregate
annual sales of approximately $186 million and forming six new hubs. This
follows 25 acquisitions in 1995 with aggregate annual sales of approximately
$108 million.

         Airgas intends to continue to actively participate in the consolidation
taking place in the fragmented industrial gas distribution market by acquiring
independent gas distributors. In seeking to acquire distributors, Airgas
anticipates competition from industrial gas producers and from certain other
independent distributors. Airgas believes that it is well positioned to acquire
distributors because of its extensive distribution network, its well-organized
acquisition program, flexibility in structuring acquisitions to meet Sellers'
needs and its ability to offer sellers and their employees a continuing
management role in a decentralized entrepreneurial environment.

         During 1996, same-store sales, a comparison of current period sales to
the prior period's sales, adjusted for acquisitions, increased 2% compared to
the prior year. Airgas' same-store sales growth rate has historically followed
the real gross domestic product annual growth rate as published by the U.S.

Department of Commerce. Weaker economic conditions compared to the prior year,
combined with inclement weather, held down same-store sales growth in 1996.
Management believes its same-store sales growth is slightly understated since it
does not reflect Airgas' decision to cease unprofitable sales to certain
customers and other sales lost during the consolidation and integration of
acquisitions.

         Future same-store sales growth is primarily dependent on the economy
and, to a lesser extent, Airgas' ability to expand markets for new and existing
products and to increase prices. Management believes Airgas' broad customer base
and geographic diversity help to reduce the adverse effects of an economic
downturn on Airgas. Also, management believes that the gas portion of its
distribution business is somewhat resistant to an economic downturn since: 1)
gases frequently represent a fixed cost of operations that do not necessarily
decline with production levels; 2) gases are required for maintenance and
renovation activities which tend to increase during an economic downturn; 3)
industries less subject to the effects of an economic downturn are major
purchasers of gases; and 4) gas purchases often represent a small portion of
typical user's overall cost of operation and, therefore, do not typically
represent a large cost-cutting item. Management further believes that sales of
certain lower margin non- consumable hardgoods equipment, such as welding
machines, are more likely to be adversely impacted during a downturn in the
economy and, conversely, are typically the fastest to rebound during an economic
recovery.

         Sales in 1996 related to gases and rent represent 51% or $408.7 million
of total distribution net sales. Bulk and specialty gas sales have increased due
to the success of gas marketing programs. In order to support and grow its
specialty gas business, Airgas has established 22 specialty gas mini-labs which
benefit customers by providing them with certain specialty gas products in their
local market. In connection with its hardgoods business, which accounted for 49%
or $392.8 million of total distribution net sales, Airgas is focused on
improving profitability by reducing its investment in inventories through the
consolidation of vendors, and the negotiation of favorable pricing based on
national purchasing arrangements.

         Airgas has recently undertaken initiatives to further develop its
industrial gas customer base to selectively include customers which require
large volume supplies of gases, such as nitrogen. For these customers, Airgas
will enter into long-term supply contracts and will construct air separation
plants near the customer's facility or facilities. Airgas has entered into
agreements with two customers and is constructing two air separation plants
which will begin production during fiscal 1998. In addition, terms related to
the agreements provide for additional sales of cylinder gases and supplies.

         Airgas remains focused on cash flow growth. Historically, operations
have generated sufficient cash flow to finance Airgas' operating requirements
while borrowings have been incurred largely to finance acquisitions. Over the
past three years, cash flow from operations has totaled approximately $230
million. This strong cash flow has helped fund Airgas' investment in
acquisitions, excluding debt assumed, and capital expenditures which, for the
past three years totaled $333.3 million and $99.3 million, respectively.

         At March 31, 1996, Airgas had unused availability of $205.0 million of
unsecured lines of credit. Airgas' debt-to-equity ratio of 1.69 at March 31,
1996 increased compared to the prior year's ratio of 1.43 primarily as a result
of acquisitions completed during 1996 combined with the purchase of treasury
stock.

          For the year ended March 31, 1996, distribution sales increased
approximately $133 million resulting from the acquisition of 66 distributors of
industrial, medical and specialty gases and related equipment since April 1,
1994 and approximately $14 million from same-store sales growth. Airgas
estimates that had all acquisitions during the year ended March 31, 1996 been
consummated on April 1, 1995, distribution sales for the year ended March 31,
1996 would have increased by an additional $100 million. The increase in
same-store sales of approximately 2% was the result of slightly higher prices
based on selected price increases to certain customers and increased volume
within its gas, rental and hardgoods businesses. During 1996, Airgas' same-store
sales increased 3% in the first quarter, 2% in the second and third quarters and
1% in the fourth quarter. Excluding the impact of the inclement weather, Airgas
estimates same-store sales growth during the fourth quarter would have been
approximately 2%. Airgas estimates same-store sales based on a comparison of
current period sales to the prior period's sales, adjusted for acquisitions.

          Sales for Airgas' manufacturing operations increased 9% during the
year ended March 31, 1996 compared to the prior year, primarily as a result of
an increase in the volume of lower margin exports and increased demand for
carbon products and nitrous oxide.

          The increase in distribution gross profit of $72.6 million over 1995
was attributable to increases associated with acquisitions of $62.7 million and
same-store gross profit growth of $9.9 million. The majority of the $9.9 million
same-store gross profit growth was derived from volume growth in gas and
increases in cylinder rent. Higher gas volumes were partially attributable to
the success of gas marketing programs, principally small bulk and specialty
gases. On a same-store basis, distribution gross margins increased an estimated
0.3% compared to 1995 primarily due to improved rent gross margins combined with
slightly higher margins in gases and hardgoods. Increased volumes of lower
margin bulk gases partially offset the gas margin improvements.

          Selling, distribution and administrative expenses decreased as
percentage of sales to 33.4% in 1996 compared to 34.3% in 1995. The decrease was
a result of acquisition consolidation efforts and lower operating costs, such as
a reduction in business insurance costs through improved claims management and
reduced incident rates. In addition, certain operating costs, such as occupancy
costs, are relatively fixed and do not increase proportionately with the
increase in same-store sales. Partially offsetting these improvements were
normal salary increases and slightly higher distribution costs.

          Distribution operating income as a percentage of net distribution
sales increased to 10.7% for the year ended March 31, 1996 compared to 10.2% in
1995. The increase in distribution operating income in 1996 was the result of
the increase in gross profits from higher same-store sales, improved gross
profit margins and operating income provided by acquisitions.

          Manufacturing operating income increased $776 thousand in 1996
compared to 1995 due to strong demand for carbon products and nitrous oxide, and
lower production and delivery costs related to calcium carbide and nitrous oxide
business, partially offset by an increase in lower margin sales of carbon
products.

         Interest expense, net, increased $7.2 million in 1996 compared to 1995
primarily as a result of the increase in average outstanding debt associated
with the acquisition of industrial gas distributors since April 1, 1994,
interest costs associated with the repurchase of Airgas common stock and
slightly higher interest rates, partially offset by an increase in positive cash
flow. As discussed in "Liquidity and Capital Resources" below, Airgas has hedged
floating interest rates under certain borrowings with interest rate swap
agreements.

         Income tax expense represented 41.8% of pre-tax earnings in 1996
compared to 43.2% in 1995. The decrease in the effective income tax rate was
primarily due to an increase in pre-tax earnings relative to permanent
differences and as a result of the implementation of certain tax planning
strategies.

         Net earnings increased 26% to $39.7 million or $.60 per share in 1996
from $31.5 million or $.48 per share in 1995. After tax cash flow increased 21%
to $96.4 million from $79.9 million in 1995.

          In 1995, distribution sales increased approximately $136 million
resulting from the acquisition of 40 industrial gas distributors since April 1,
1993 and approximately $32 million from same-store sales. Based on unaudited
historical pro forma data, Airgas estimates that had all 1995 acquisitions been
consummated on April 1, 1994, distribution sales for 1995 would have been
approximately $49 million higher. The increase in same-store sales of
approximately 5% is primarily the result of increased volume

                                       57
<PAGE>
 
of hardgoods sales and increases in gas and rental businesses. Airgas estimates
same-store sales based on a comparison of current period sales to the prior
period's sales, adjusted for acquisitions. Hardgoods and gas volumes have
primarily increased as a result of the general improvement in the economy and
certain gas marketing programs. Same-store sales have also increased slightly as
a result of price increases initiated during 1995 and 1994 Airgas believes that
sales of hardgoods are adversely impacted during a recession, and conversely,
are typically the fastest to rebound during an economic recovery.

          Sales for Airgas' manufacturing operations increased slightly compared
to 1994 primarily as a result of an increase in the volume of lower margin
products.

          Compared to 1994, distribution gross profit increases associated with
acquisitions totaled an estimated $69 million. Gross profits associated with
distribution same-store sales growth are estimated to total $16 million. The
same-store gross profit growth is attributable to increased hardgoods volumes
combined with improved gross margins resulting from Airgas' national purchasing
arrangements, success of gas marketing programs and improved gas and rental
gross margins due to price increases to customers. On a same-store basis,
considering the impact of the change in Airgas' sales mix slightly towards lower
margin hardgoods sales, distribution gross margins increased an estimated .6%
compared to 1994.

         Selling, distribution and administrative expenses as a percentage of
sales decreased to 34.3% compared to 34.8% in 1994. The decrease is a result of
acquisition consolidation efforts and from controlling certain operating costs,
such as business insurance through improved claims management and reduced
incident rates. Through improved billing and collection efforts, Airgas has also
reduced its bad debt expense and lowered its accounts receivable days sales
outstanding to 44 days compared to 49 days at March 31, 1994. In addition,
certain operating costs, such as occupancy costs, are relatively fixed even
though Airgas' same-store sales increased over 1994. Partially offsetting these
improvements were normal salary increases.

         Operating income increased 49% in 1995 compared to 1994:

          Distribution operating income as a percentage of net distribution
sales increased to 10.2% compared to 8.7% in 1994. The increase in distribution
operating income in 1995 was a result of the increase in gross profits from
higher same-store sales, operating income provided by acquisitions and improved
gross profit margins.

<PAGE>
 
          Manufacturing operating income decreased $189 thousand compared to the
prior year due to a product shift towards lower margin export sales of carbon
products, slightly lower profits from the sale of calcium carbide combined with
higher raw material costs, principally ammonium nitrate, for the Airgas' nitrous
oxide plants.

          Interest expense, net, increased $5.1 million compared to 1994
primarily as a result of the increase in average outstanding debt associated
with the acquisition of industrial gas distributors since April 1, 1993 combined
with slightly higher interest rates. As discussed in "Liquidity and Capital
Resources" below, Airgas has hedged floating interest rates under certain
borrowings with interest rate swap agreements.

         Income tax expense represented 43.2% of pre-tax earnings in 1995
compared to 44.1% in 1994. The decrease in the effective income tax rate is
primarily due to an increase in pre-tax earnings relative to permanent
differences.

         Net earnings increased 55% to $31.5 million or $.48 per share in 1995
from $20.3 million or $.31 per share in 1994. After tax cash flow (net earnings
plus depreciation, amortization and deferred income taxes) increased 35% to
$79.9 million from $59.1 million in 1994. After tax cash flow is an important
measurement of Airgas' ability to repay debt through operations and provides
Airgas with the ability to pursue investment alternatives such as acquisitions
and the repurchase of Airgas stock.

Liquidity and Capital Resources

         Airgas has primarily 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 $38.5 million for the nine
months ended December 31, 1996. Depreciation, depletion and amortization
represented $45.8 million of cash flows from operating activities. Working
capital components of cash flow increased $41.2 million as a result of an
increase in accounts receivable associated with higher same-store sales, an
increase in inventory levels to meet increased hardgoods and gas sales volumes
and an increase in prepaid expenses and other current assets. Prepaid expenses
and other current assets include $23.7 million of costs associated with the
fraudulent breach of contract related to refrigerant R-12 purchases. The
increase in other assets and liabilities, net, primarily relates to amounts paid
in connection with securing product supply agreements. Days-sales outstanding
and distribution hardgoods days supply of inventory improved slightly compared
to March 31, 1996 levels. Total inventories have increased primarily as a result
of an increase in distribution inventories of $6.5 million to support sales
growth, and gases of $10 million associated with specialty gas sales
initiatives.

         Cash used by investing activities totaled $250.8 million which was
primarily comprised of $48.1 million for capital expenditures, $169.1 million
related to acquisitions and $34.2 million related to Airgas' investment in
unconsolidated affiliates ($27.9 related to the joint venture with National
Welders and $6.3 million related to foreign investments).

         Airgas' use of cash for capital expenditures was attributable to the
continued assimilation of certain acquisitions requiring capital expenditures

fleets and purchasing cylinders in order to return cylinders which were rented
from third parties. Additionally, capital expenditures include the purchase of
cylinders and bulk tanks necessary to facilitate gas sales growth. Airgas
estimates that its maintenance capital expenditures are approximately 2% of net
sales. Airgas considers the replacement of existing capital assets to be
maintenance capital expenditures.

         Airgas has recently undertaken initiatives to further develop its
industrial gas customer base to selectively include customers which require
large volume supplies of gases, such as nitrogen. For these customers, Airgas
plans to enter into long-term supply contracts in conjunction with air
separation plants which will be built near the customer's facility or
facilities. Airgas has entered into agreements with two customers which requires
the construction of two air separation plants which will begin production during
fiscal 1998. Upon completion, as lessee, Airgas intends to lease the plants
under long-term operating leases.

         Financing activities provided cash of $212.4 million with total debt
outstanding increasing by $252.1 million from March 31, 1996. Funds borrowed in
connection with the acquisition of distribution businesses and Airgas'
investment in National Welders and other foreign investments, totaled $203.3
million.

         Airgas' primary source of borrowing is a $500 million unsecured
revolving credit facility with various commercial banks which matures on
September 30, 2001. At December 31, 1996, Airgas had approximately $357 million
in borrowings under the facility and approximately $84 million committed under
letters of credit, resulting in unused availability under the facility of
approximately $59 million.

         On August 8, 1996, Airgas commenced a medium-term note program pursuant
to a registration statement filed with the Securities and Exchange Commission on
July 15, 1996, which provides for the issuance of its securities with an
aggregate public offering price of up to $450 million. In September 1996, Airgas
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%. In March 1997, Airgas issued $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.

         Airgas has a C$50 million Canadian credit facility (US$37 million) with
various commercial banks which matures on November 14, 1998.  At December 31,
1996, Airgas had approximately C$42 million (US$31 million) in borrowings
outstanding under the facility, resulting in unused availability under the
facility of approximately C$8 million (US$6 million).

         Airgas also has unsecured line of credit agreements with various
commercial banks. At December 31, 1996, these agreements totaled $50 million,
under which Airgas had no borrowings outstanding.

         At December 31, 1996, the effective interest rate related to
outstanding borrowings under all credit lines was approximately 6.04%. Airgas'
loan agreements contain covenants which include the maintenance of a minimum
equity level and maintenance of certain financial ratios.

                                       60
<PAGE>
 
         In managing interest rate exposure, principally under Airgas' floating
rate revolving credit facilities, Airgas has entered into 21 interest rate swap
agreements during the period from June 1992 through December 31, 1996. The swap
agreements are with major financial institutions and aggregate $324 million in
notional principal amount at December 31, 1996. Approximately $205 million of
the notional principal amount of the swap agreements require fixed interest
payments based on an average effective rate of 6.53% for remaining periods
ranging between 1 and 8 years. Five swap agreements require floating rates
($119.5 million notional amount at 5.75% at December 31, 1996). Under the terms
of seven of the swap agreements, Airgas has elected to receive the discounted
value of the counterparty's interest payments upfront. At December 31, 1996,
approximately $19.7 million of such payments were included in other liabilities.
Airgas continually monitors its positions and the credit ratings of its
counterparties, and does not anticipate nonperformance by the counterparties.

         Airgas 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. In connection with the acquisition of Rutland, Airgas
issued approximately 3.4 million shares of its Common Stock, including
approximately 2.4 million treasury shares.

         On October 29, 1996, Airgas announced that it signed a letter of intent
to acquire CIC. In the proposed transaction, CIC will be merged into a
newly-formed subsidiary of Airgas in exchange for a combination of Airgas'
Common Stock and cash, and is expected to close during the first quarter of
fiscal 1998.

         Subsequent to December 31, 1996, Airgas acquired industrial gas
distribution businesses with aggregate annual sales of approximately $12
million.
   
         In December 1996, the Board of Directors authorized the repurchase
of up to 1,600,000 shares of Airgas Common Stock, and on April 16, 1997, the
Board of Directors authorized the repurchase of up to 1,000,000 additional
shares. Airgas purchased 14,700 shares of Airgas Common Stock during the quarter
ended December 31, 1996. Subsequent to December 31, 1996 and through April 17,
1997, Airgas repurchased 1,689,300 shares, leaving a total of 896,000 shares
available under the repurchase program. Airgas' treasury shares will be used to
fund acquisitions and employee benefit programs and will be acquired in open
market transactions, from time-to-time, depending on market conditions.    

         Airgas does not currently pay dividends.

Other

         New Accounting Pronouncements

         In the first quarter of fiscal 1997, Airgas adopted SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of." The statement requires the recognition of an impairment loss
for an asset held for use when the estimate of undiscounted future cash flows
expected to be generated by the asset is less than its carrying amount.
Measurement of the impairment loss is based on fair value of the asset.

                                       61
<PAGE>
 
         Management believes that the adoption of this statement did not have a
material impact on earnings, financial condition or liquidity of Airgas.

         Airgas accounts for stock options according to the provisions of
Accounting Principles Board Opinion 25 (APB 25), "Accounting for Stock Issued to
Employees." In October 1995, the Financial Accounting Standards Board issued
FASB Statement No. 123, "Accounting for Stock-Based Compensation." The new
standard defines a fair value method of accounting for stock options and similar
equity instruments. Companies may elect to continue to use existing accounting
rules or adopt the fair value method for expense recognition. Companies that
elect to continue to use existing accounting rules are required to provide
pro-forma disclosures of net income and earnings per share assuming the fair
value method was adopted. Airgas has elected to continue to use existing
accounting rules. Accordingly, Airgas will present the required pro-forma
disclosure provisions for its fiscal year ending March 31, 1997. As Airgas will
continue to account for stock-based compensation using the intrinsic value
method, this statement will not have a material impact on earnings, financial
condition or liquidity of Airgas.

         In June 1996, the Financial Accounting Standards Board issued 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. Under the financial-components approach, after a transfer of
financial assets, an entity recognizes all financial and servicing assets it
controls and liabilities it has incurred and derecognizes financial assets it no
longer controls and liabilities that have been extinguished. The
financial-components approach focuses on the assets and liabilities that exist
after the transfer. If a transfer does not meet the criteria for a sale, the
transfer is accounted for as a secured borrowing with pledge of collateral. 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. Management believes that the adoption
of this statement will not have a material impact on earnings, financial
condition or liquidity of Airgas.

         In October 1996, the American Institute of Certified Public Accountants
issued 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. Management believes that the adoption of this
statement will not have a material impact on earnings, financial condition or
liquidity of Airgas.

         Forward-looking Statements

         This Proxy Statement/Prospectus contains forward-looking statements. In
connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, there are certain important factors that could
cause Airgas' actual results to differ materially from those included in such
forward-looking statements. Some of the important factors which could cause
actual results to differ materially from those projected include, but are not
limited to: Airgas' ability to continue to identify,

Business

         General

         Airgas classifies its operations in three business segments:
distribution, direct industrial and manufacturing. Sales for Airgas were $838,
$688 and $519 million in fiscal 1996, 1995, and 1994, respectively. Sales were
$850 and $602 million for the nine months ended December 31, 1996 and 1995,
respectively. Distribution sales represented 96% of total sales and 93% of
Airgas' operating income in fiscal 1996, and represented 89% of the total sales
and 91% of operating income for the nine months ended December 31, 1996.
Financial information by business segment can be found in note 20 to Airgas'
consolidated financial statements for the three years ended March 31, 1996 and
"-- Management's Discussion and Analysis of Financial Condition and Results of
Operations" for the nine months ended December 31, 1996 and 1995, respectively.

         The distribution business is conducted through approximately 600
locations in 41 states, Canada and Mexico. Principal products distributed
include: industrial, medical and specialty gases and a wide selection of
name-brand welding equipment, accessories and industrial protective equipment
("hardgoods"), including electrode holders, welding wire, cable lugs and
connectors, hard hats, welding helmets, hearing protectors, goggles, face
shields, safety glasses, welding machines and electrodes. In connection with the
distribution of gases, Airgas rents industrial gas cylinders and bulk storage
tanks to its customers. Additionally, acetylene gas is manufactured and sold as
part of Airgas' distribution business. Since its formation, Airgas' strategy has
been to expand through the acquisition of independent distributors. Airgas
believes that it is the largest distributor of industrial, medical and specialty
gases and related equipment in North America.

         During the 1997 fiscal year, Airgas acquired IPCO and Rutland . IPCO
and Rutland provide additional product lines and management talent to form the
base for Airgas' industrial distribution segment, ADI.

         Manufacturing operations include the production of carbon products,
calcium carbide, nitrous oxide and carbon dioxide.

                                       63

         The Distribution Business

         Industry Background. The industrial gas distribution market is broad
         -------------------
and includes customers from most major industries. Airgas sells nitrogen,
oxygen, argon, helium, acetylene, carbon dioxide, nitrous oxide, hydrogen and
welding gases and a variety of medical and specialty gases to a diverse customer
base. Gases are distributed and stored in industrial gas cylinders and bulk
storage tanks. Hardgoods sold through its distribution network include:
protective equipment, such as hard hats, welding helmets, goggles, face shields
and protective glasses; welding machines and welding consumables; and
accessories, such as electrodes, electrode holders and cable connectors.

         The United States market for industrial gases is approximately $6.5
billion annually. Sales to major users of industrial gases that have the
capacity to accept large bulk shipments or pipeline deliveries are generally
serviced directly by industrial gas producers and account for approximately $3.5
billion of such market. Historically, industrial gas producers have focused on
this segment of the market, which is capital intensive. The remaining $3.0
billion of annual industrial gas sales are made to small bulk users and cylinder
gas customers. These small bulk users and cylinder gas customers are also
believed to purchase approximately $3.5 billion of hardgoods annually. Small
bulk users and cylinder gas customers are served by a fragmented distribution
system of approximately 1,000 distributors, the majority of which are
independently owned. Airgas concentrates on the small bulk, cylinder gas,
welding and protective equipment segment of the market. This segment is less
capital intensive, in part, because of the long useful lives of the fixed
assets, principally cylinders.

         Airgas Strategy-Acquisition Program. Since May 1986, Airgas has
         -----------------------------------
acquired over 225 distributors of industrial gas and related equipment. These
distributors are organized into five operating divisions with approximately 600
locations in 41 states, Canada and Mexico. The five operating divisions provide
Airgas with a national distribution network that is unique to the industry. In
addition, on June 28, 1996, based on the terms of a joint venture agreement,
Airgas acquired 45% of the voting capital stock of National Welders, a major
distributor of industrial, medical and specialty gases and related equipment
based in Charlotte, North Carolina. The purpose of the joint venture is to carry
on the business of NWS, enhanced by its association with Airgas and its
financial, purchasing and national marketing strengths, and to pursue
acquisition opportunities in the area currently served by National Welders.

         Airgas' principal business strategy is to continue to expand its
distribution network through a program of acquiring independent distributors.
The industrial gas distribution industry continues to undergo a consolidation
process which Airgas believes will continue to present it with opportunities to
acquire industrial gas distributors.

         Airgas believes that its principal competitive advantages in acquiring
distributors are its extensive distribution network, its well-organized
acquisition program, flexibility in structuring acquisitions to meet sellers'
needs and ability to offer sellers and their employees a continuing management
role in a decentralized entrepreneurial environment. In seeking to acquire
distributors, Airgas competes with industrial gas producers and other
independent distributors.

          Airgas has made investments in industrial gas operations in Poland,
India and Thailand. At December 31, 1996, the total investment in these foreign
operations was less than 1% of total assets. Airgas will

                                       64
<PAGE>
 
continue to evaluate foreign industrial gas opportunities, although its
principal focus remains on North American expansion.

         Airgas has financed distributor acquisitions primarily with internally
generated funds and debt. Airgas has been able to obtain debt financing due, in
part, to its ability to generate cash flow from operating activities and the
long useful lives and relatively stable market values of the fixed assets,
principally cylinders.

         Operating Policies. Airgas believes that its operations are best
         ------------------
managed at the local level by entrepreneurial, incentive-driven executives with
backgrounds principally in the industrial gas industry. The president of each
distribution subsidiary is typically a former owner or key employee of the
acquired business or an experienced executive recruited by management. The
continuity afforded by retaining the key employees of an acquired business
combined with local management is essential because Airgas' distribution
business is local in nature and is dependent upon satisfied repeat customers.

         Customer Base. The majority of Airgas' gases are generally stored in
         -------------
bulk tanks at Airgas' cylinder fill plants and are pumped into cylinders for
distribution to customers or, in the case of bulk customers, in tanker trucks or
tube trailers for delivery into bulk tanks at the customer's business location.
Airgas emphasizes sales to cylinder and small bulk gas customers.

         The distribution of industrial gases historically has been to customers
engaged in the business of welding and metal fabrication. In order to better
serve these customers, industrial gas distributors have traditionally sold
hardgood items through their distribution branch locations. As certain sectors
of the economy have grown, such as the electronics and chemicals industries, and
as new applications for gases have developed, the customer base of the gas
distribution business has broadened significantly to include businesses in
almost every major industry, from medical and high technology to consumer and
basic industries. For example, the food and beverage industry uses carbon
dioxide and nitrogen; the electronics industry uses oxygen, nitrogen, argon, and
hydrogen; the healthcare industry uses oxygen, nitrogen, and nitrous oxide; and
the chemical and fiber industries use nitrogen.

         Specialty gases, which are used in numerous industries and in
electronic and laboratory applications, include rare gases, high- purity gases,
and blended multi-component gas mixtures. Airgas helps service its specialty gas
customers through its 22 specialty gas mini-labs which operate in 17 states.
Airgas anticipates continuing growth in this product area. The principal drivers
for market growth include: (1) environmental regulations, such as the Clean Air
Act, water testing and pollution remediation and testing and monitoring; (2)
quality control services using in-line chromatography and spectrography to
analyze samples; and (3) the growth of environmental, research and clinical
laboratories.

         Airgas has also concentrated its efforts in the small bulk gas market.
The primary gases that Airgas sells in bulk are liquid oxygen, nitrogen, argon,
and carbon dioxide, and gaseous hydrogen, helium and nitrogen. Airgas charges
customers rent for the use of bulk tanks and tube trailers which are placed on
the customer's property Airgas believes there are growth opportunities in
marketing to these small bulk customers, which it can serve more effectively
than industrial gas producers.

         Airgas has recently undertaken initiatives to further develop its
industrial gas customer base to selectively include customers which require
large volume supplies of gases, such as nitrogen. For these

                                       65
<PAGE>
 
customers, Airgas will enter into a long-term supply contract and will construct
an air separation plant near the customer's facility or facilities. Airgas has
entered into agreements with two customers and is constructing two air
separation plants which will begin production during fiscal 1998. In addition,
terms related to the agreements provide for additional sales of cylinder gases
and supplies.

         Airgas' same-store sales, a comparison of current period sales to the
prior period's sales, adjusted for acquisitions, has historically followed the
real gross domestic product annual growth rate as published by the Commerce
Department. Management believes Airgas' broad customer base and geographic
diversity help to reduce the adverse effects of an economic downturn on Airgas.
Also, management believes that the gas portion of its distribution business is
somewhat resistant to economic downturns due to the following factors: 1) gases
frequently represent a fixed cost of operations that do not necessarily decline
with production levels; 2) gases are required for maintenance and renovation
activities which tend to increase during an economic downturn; 3) industries
less subject to the effects of an economic downturn, such as the medical field,
are major purchasers of gases; and 4) gas purchases often represent a small
portion of a typical user's overall cost of operation and, therefore, do not
typically represent a large cost-cutting item. Management further believes that
sales of certain lower margin non- consumable hardgoods equipment, such as
welding machines, are more adversely impacted during a downturn in the economy
and are typically the fastest to rebound during an economic recovery.

         Products. Gases distributed by Airgas include oxygen, nitrogen,
         --------
hydrogen, argon, helium, acetylene, carbon dioxide, nitrous oxide and specialty
gases. In addition to gases, Airgas distributes a wide selection of name-brand
hardgoods, including electrode holders, welding wire, cable lugs and connectors,
hard hats, welding helmets, hearing protectors, goggles, face shields, safety
glasses, welding machines and electrodes. Of Airgas' fiscal 1996 sales from
distribution, approximately 51% represent sales of gases and rentals of
cylinders and bulk tanks, and 49% represent hardgood sales. Of distribution
sales for the nine months ended December 31, 1996, 50% represent sales of gases
and rent, and 50% represent hardgood sales.

         Airgas intends to strategically broaden its product line in order to
increase sales in existing locations and to take advantage of its distribution
network. Recent product line additions have included returnable containers,
specialty gases and additional hardgoods (such as industrial safety products and
coatings). Airgas believes the selective addition of complementary product
offerings through its distribution network and ADI will enable it to better
serve its diverse, expanding customer base.

         Suppliers. Airgas purchases industrial, medical and specialty gases
         ---------
pursuant to requirements contracts from all four of the major producers of
industrial gases in the United States and three regional producers. Airgas
believes that if a contractual arrangement with any supplier of gases were
terminated, it would be able to locate alternative sources of supply without
significant cost increases and with no disruption of service.

         Airgas purchases hardgoods from name-brand manufacturers and suppliers.
For certain products, Airgas has negotiated favorable pricing based on national
purchasing arrangements and is reducing its investment in hardgood inventories
by consolidating vendors.

                                       66
<PAGE>
 
         Direct Industrial Business

         During the 1997 fiscal year, Airgas acquired IPCO and Rutland, which
have aggregate annual sales of $120 million. IPCO and Rutland provide additional
product lines and management talent to form the base for the Company's
industrial distribution segment, ADI. IPCO is a distributor of safety,
industrial and environmental supplies, and utilizes a system of regional
warehouses and telemarketing centers to market its products. Rutland is a
distributor of industrial tools, MRO supplies and welding and safety equipment,
and markets its products through direct mail, catalogs and monthly flyers. ADI's
objective is to facilitate the growth of safety products and other industrial
supplies through the Airgas distribution network. Airgas' strategy is to acquire
additional industrial distribution companies with a focus on increasing
same-store sales of new industrial product lines through both the acquired
businesses and its existing distribution network.

         Manufacturing and Related Businesses

         Nitrous Oxide. Airgas produces nitrous oxide which is used in various
         -------------
medical and commercial applications. Nitrous oxide is used as an anesthetic in
the medical and dental fields, as a propellant in the packaged food business and
is utilized in the manufacturing process of certain high technology electronic
industries. Airgas' nitrous oxide manufacturing facilities are located in Yazoo
City, Mississippi and Donora, Pennsylvania.

         Carbon Products. Airgas manufactures carbon electrode paste, carbon
         ---------------
ramming paste and electrically calcined anthracite ("ECA") at its manufacturing
facility located in Keokuk, Iowa. Airgas is the nation's primary manufacturer of
carbon electrode paste which is used as a consumable electrode in the production
of special alloy steel, nickel and other metals. ECA is used as an ingredient in
carbon mixes used in the aluminum industry and as an additive in the production
of certain metals. Sales of electrode paste and ECA are conducted through a
marketing organization which owns more than five percent of Airgas' outstanding
common stock.

         Calcium Carbide. Airgas is a partner with Elkem Metals Company
         ---------------
("Elkem") in a joint venture (Elkem-American Carbide Company) which primarily
sells calcium carbide which is used in the production of acetylene gas. Airgas
and Elkem receive certain fees, based on net sales, for acting as agents for the
joint venture. Additionally, as general manager of the joint venture, Elkem
receives a management fee based on net sales. Airgas operates a manufacturing
facility in Pryor, Oklahoma which sells calcium carbide to the joint venture.

         Carbon Dioxide. On December 1, 1996, Airgas acquired interests in
         --------------
unitized leases producing carbon dioxide in the Northeast Jackson Dome area of
Mississippi and an attached 183-mile carbon dioxide pipeline stretching from the
Northeast Jackson Dome area to White Castle, Louisiana. The pipeline services
three major liquid carbon dioxide producers (including CIC) and a major methanol
producer, each pursuant to a long-term supply contract, as well as a group of
enhanced oil recovery fields.

                                       67
<PAGE>
 
         Competition

         Each of the major business areas in which Airgas participates is highly
competitive. Some competitors are larger than Airgas and have greater resources.

         Airgas' industrial gas distribution operations compete with independent
distributors and vertically integrated gas producers such as Air Products and
Chemicals, Inc., Praxair, Inc., Liquid Air Corporation of America, BOC Gases
Group and others, all of which have distribution operations. Airgas also
purchases industrial gases pursuant to requirements contracts from all four of
the above major producers of industrial gases.

          Competition in the distribution market is based on customer service,
prompt delivery, price, consistent product quality, attention to safety
procedures, and employee and customer training in the uses of gases and
hardgoods. Airgas believes its decentralized system allows competitive decisions
to be made on the local level which results in reduced costs and/or improved
service. In addition, Airgas' size allows it to realize economies of scale in
purchasing, training, marketing and information systems.

         Regulatory and Environmental Matters

         The businesses of Airgas' subsidiaries are subject to federal and state
laws and regulations adopted for the protection of the environment and the
health and safety of employees and users of Airgas' products. Airgas has
programs for the operation and design of its facilities to achieve compliance
with applicable environmental rules and regulations. Airgas believes that it is
in compliance in all material respects with such laws and regulations.
Expenditures for environmental purposes during the fiscal year ended March 31,
1996 and the nine months ended December 31, 1996 were not material.

         Insurance

         Airgas' policy is to obtain liability and property insurance coverage
that is currently available at what management determines to be a fair and
reasonable price. As of December 31, 1996, Airgas had a liability insurance
limit of $100 million. The liability insurance is subject to per-occurrence
deductible amounts of $1 million for product liability, general liability and
workers' compensation claims, and approximately $500 thousand for motor vehicle
liability.

         The nature of Airgas' business may subject it to product and general
liability lawsuits. To the extent that Airgas is subject to claims which exceed
its liability insurance coverages, such suits could have a material adverse
effect on Airgas' financial position, results of operations or liquidity.

         Employees

         On December 31, 1996, Airgas employed approximately 6,500 people of
whom approximately 6% were covered by collective bargaining agreements. Airgas
believes it has good relations with its employees and has not experienced a
strike or work stoppage in the past 10 years.

         Patents, Trademarks and Licenses

         Airgas holds trademark registrations for "Airgas", "Dyna-Switch" and
"Va-Weld", and a patent registration for the purification of acetonitrile.
Airgas believes that its businesses as a whole are not materially dependent upon
any single patent, trademark or license.

Properties

         Airgas has offices, manufacturing and distribution facilities in 41
states, Canada and Mexico. The principal executive offices of Airgas are located
in leased space in Radnor, Pennsylvania.

         Airgas' manufacturing segment produces carbon products at its Keokuk,
Iowa, facility; calcium carbide at its Pryor, Oklahoma, facility; and nitrous
oxide at its Donora, Pennsylvania and Yazoo City, Mississippi facilities.
Manufacturing facility utilization, based on market demand, has ranged from 65%
to 100%.

         The Keokuk and Pryor facilities are owned by Airgas. The Donora plant
is located on property leased through the year 2006. The Yazoo City property is
owned by Airgas; however, it will revert to the local municipality if the plant
terminates operations. The Keokuk, Pryor and Donora facilities are pledged as
collateral under Industrial Development Board revenue bonds (see note 8 to
Airgas' consolidated financial statements.).

         Airgas' distribution segment conducts business from its locations in 41
states, Canada and Mexico. These locations are either owned or are leased from
third parties or from employees of Airgas who were previous owners of businesses
acquired on terms consistent with commercial rental rates prevailing in the
surrounding rental market. 17 distribution locations in 12 states have acetylene
manufacturing plants. Airgas' acetylene plants operate at approximately 60% of
capacity.

         Airgas believes that its facilities are adequate for its present needs
and that its properties are generally in good condition, well maintained and
suitable for their intended use.

Litigation

         Airgas and its subsidiaries are parties to pending legal proceedings
arising out of their business operations. The proceedings involve claims for
personal injuries, breach of contract, product warranty and product design, and
claims involving employee relations and certain administrative proceedings.
Except as discussed below, management does not believe that the eventual outcome
of any litigation to which Airgas or its subsidiaries are parties would have a
material adverse effect on the consolidated financial position, results of
operations or liquidity.

         On July 26, 1996, Praxair, Inc. ("Praxair") filed suit against Airgas
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 Airgas in connection with
Airgas' 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

                                       69
<PAGE>
 
Airgas' motion to dismiss for forum non conveniens. Airgas has filed a petition
for writ of mandamus with the Alabama Supreme Court requesting that the lower
court's order be vacated or set aside. Airgas believes that Praxair's claims are
without merit and intends to defend vigorously against such claims.

         On September 9, 1996, Airgas 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 Airgas, pursuant to which Praxair
induced Airgas to provide Praxair valuable information and conclusions developed
by Airgas concerning CBI Industries, Inc. ("CBI") in exchange for Praxair's
promise not acquire CBI without Airgas' participation. Airgas 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. Airgas is seeking compensatory
and punitive damages. On January 2, 1997, the court entered an order overruling
Praxair's preliminary objections to Airgas' complaint and ordering Praxair to
file an answer to the complaint. Praxair has since filed an answer and asserted
various defenses.

         On February 12, 1997, Airgas filed a lawsuit in the United States
District Court for the Southern District of Georgia against Discount Auto Parts,
Inc. ("Discount"), an employee of Discount, and certain other business and
individual defendants, alleging that Discount and the other defendants engaged
in racketeering activity involving the fraudulent sale of smuggled and
counterfeit R-12 refrigerant gas. Airgas' complaint alleges that the
racketeering activity of the defendants caused damages to Airgas in an amount
not less than $20 million. The complaint seeks treble damages under the Federal
RICO and Georgia RICO statutes, as well as monetary damages under other counts
alleging fraud, conspiracy and related wrongful conduct. On December 23, 1996,
Airgas had reported that it had been a victim of a fraudulent breach of contract
by a supplier. That incident was part of the racketeering activity alleged in
the lawsuit filed.

         Compensation of Directors

         Directors (other than those who are employees of Airgas) are paid an
annual retainer of $9,000 plus a fee of $1,000 for each Board or Committee
meeting attended, and are entitled to participate in the 1989 Non-Qualified
Stock Option Plan for Directors (Non-Employees) (the "Directors' Plan"). Under
the Directors' Plan, on the date of each annual meeting of stockholders,
continuing directors are granted options to purchase 8,000 shares of Airgas'
Common Stock at an exercise price equal to the fair market value on the date of
grant. The options are exercisable immediately and have terms of 10 years.
Messrs. Brown, Foster, Hoak, Naylor, Shober, Sult, Stott and Yohe each received
options to acquire 5,000 shares adjusted to reflect the 2-for-1 stock split in
April 1996 (after they each waived their right to options to acquire 3,000
shares) in fiscal 1996. The Chairman of the Audit Committee and the Nominating
and Compensation Committees also receive an additional $3,000 annual retainer.
Directors are also reimbursed for their travel expenses for attendance at Board
and Committee meetings.

         From April 1, 1995, through March 31, 1996, Mr. Stott was paid $10,000
for consulting services he rendered to Airgas.

         Section 16(a) Beneficial Ownership Reporting Compliance

         Section 16(a) of the Securities and Exchange Act of 1934 requires
Airgas' officers and directors, and persons who own more than ten percent of a
registered class of Airgas' equity securities, to file reports of ownership and
changes in ownership of the securities with the SEC and the NYSE. Such persons
are also required to furnish Airgas with copies of all Section 16(a) forms they
file. Airgas knows of no greater than ten percent stockholders, other than one
person who is an officer and director.

         Based solely on its review of the copies of the forms received by it
with respect to the 1996 fiscal year, or written representations from certain
reporting persons that no Forms 5 were required, Airgas believes that all of its
officers and directors complied with all filing requirements applicable to them,
except with respect to one late filing of a Form 4 to report the sale of 353
shares of Airgas' Common Stock by E. Pat Baker in August 1995, which Form 4 was
filed in September 1996, two weeks late. Additionally, 215 shares of Airgas'
Common Stock acquired by Mr. Baker on March 31, 1995, pursuant to Airgas' 1994
Stock Purchase Plan was inadvertently omitted from Mr. Baker's Form 3. The
acquisition of shares was made one day before the date on which Mr. Baker became
an executive officer for purposes of Section 16(a). Upon discovery of the error,
an amendment was promptly filed.

(1)      These amounts, based on assumed appreciation rates of 0%, 5% and 10%
         prescribed by the Securities and Exchange Commission rules, are not
         intended to forecast possible future appreciation, if any, of Airgas'
         stock price.
(2)      Options to acquire shares of Common Stock, which become exercisable in
         four equal annual installments beginning May 22, 1996.
(3)      No gain to the Optionees is possible without an increase in stock
         price, which will benefit all stockholders. If the named executive
         officers realize the appreciated values based on the 5% and 10%
         appreciation rates set forth in the table, total stockholder value will
         have appreciated by approximately $584 million and $1.481 billion,
         respectively, and the value of the named executive officers'
         appreciation will be approximately 0.3% of the total stockholders'
         appreciation. Potential stock price appreciation to all stockholders is
         calculated based on a total of 64,265,320 shares of Common Stock
         outstanding on June 10, 1996, and a price of $14.46 per share, the
         weighted average exercise price of options granted in fiscal 1996
         referred to in the table above.

         Termination of Employment and Change in Control Arrangement

         Airgas has agreed that upon Mr. McCausland's termination of employment
or change in control of Airgas, he is entitled to a payment equal to two times
annual salary, the continuation of health insurance and other employee benefits
for a three-year period and automatic vesting of all previously granted stock
options.

         Certain Transactions

         As a condition to the amendment in January 1991 of warrants held by Mr.
McCausland, Mr. McCausland exercised warrants and the Company agreed to provide
financing assistance, including a guarantee of a bank loan in the principal
amount of $1,116,695, to Mr. McCausland, the proceeds of which were used by Mr.
McCausland to purchase shares under certain of the warrants. The loan was
guaranteed by the Company until July 23, 1993 and was repaid by Mr. McCausland
on September 9, 1993. In addition, the Company has agreed to guarantee an
individual loan for, or to lend to Mr. McCausland directly, the amount of taxes,
if any, which may be payable by reason of the warrant exercise.

         On February 28, 1994, Alfred B. Crichton, Division President-Western
Division, William Sanford, Vice President - Marketing, E. Pat Baker, Division
President-Eastern Division, Rudi G. Endres, Vice President-International, and
Mr. Knieling elected to exchange minority equity interests they

                                       77
<PAGE>
 
held in subsidiaries of Airgas for 15,463, 17,610, 3,805, 27,366 and 7,951
shares, respectively, of Airgas Common Stock pursuant to Exchange Rights
Agreements entered into between Airgas and such persons. Pursuant to the
agreements, Airgas' Board of Directors designated February 28, 1994 as an
exchange date. The number of shares of Airgas Common Stock issued in exchange
was determined based on a valuation of the subsidiary's shares on September 30,
1993, as reviewed by an independent appraiser, and the market price of Airgas
Common Stock as of November 1, 1993.

         McClain Corporation ("McClain"), Woodstock, Illinois, whichwas the
beneficial owner of more than five percent of Airgas' Common Stock, is the
exclusive sales agent of a subsidiary of Airgas for the sale and marketing of
certain products, including electrically calcined anthracite and electrode
paste, under a sales agency agreement which was renewed by the parties in
October 1993 for a ten-year term (the "Sales Agency Agreement"). The Sales
Agency Agreement provides for the payment of commissions to McClain equal to 5%
of the sales for all Company products sold under the Sales Agency Agreement by
McClain. During the fiscal years ended March 31,1994, 1995 and 1996, Midwest
Carbide, a wholly-owned subsidiary of Airgas, paid McClain $515,000, $543,000
and $685,000, respectively, pursuant to the Sales Agency Agreement. Airgas
believes the amounts paid to McClain are not inconsistent with industry
practices.

         Airgas leases two properties from Mr. Knieling under two leases that
expire in fiscal 1997. During fiscal 1994, 1995 and 1996, Airgas made rental
payments to Mr. Knieling in the aggregate amounts of $64,200, $70,000 and
$64,800, respectively. The leases were executed in connection with the purchase
by Airgas of Mr. Knieling's business prior to his employment by Airgas. Airgas
believes that the terms of the leases are no less favorable than could have been
obtained in arms-length transactions with unaffiliated third parties.

         In fiscal 1994, National Welders, of which Mr. Sult was the President,
paid $1,107,219 to a joint venture of Airgas for the purchase of calcium
carbide. In fiscal 1995 and 1996, National Welders paid $546,000 and $495,000,
respectively, to Airgas for the purchase of nitrous oxide and $1,209,000 and
$987,000, respectively, to a joint venture of Airgas for the purchase of calcium
carbide. In addition, during fiscal 1996, National Welders paid $109,000 to
Airgas for the purchase of specialty gases. On June 28, 1996, Airgas acquired,
pursuant to the terms of a joint venture agreement, 45% of the voting capital
stock of National Welders for cash and notes totaling approximately $47.6
million. In connection with the agreement, during the three-year period
beginning on July 1, 2006, the major shareholders of National Welders have the
right to cause National Welders to redeem their National Welders preferred stock
for either $58.1 million in cash or to exchange such preferred stock for
approximately 2.38 million shares of Airgas Common Stock. Airgas believes that
the terms of the transactions are no less favorable than could have been
obtained in arms-length transactions with unaffiliated third parties.

         Airgas leases cylinders from William A. Rice, Jr., Division President -
Industrial Distribution and Purchasing, of Airgas, under a capital lease
continuing through December 1997. The lease was executed in connection with the
purchase by Airgas of Mr. Rice's business prior to his employment by Airgas.
During its 1995 and 1996 fiscal years, Airgas made principal and interest
payments totaling $174,000 in each such year under the cylinder lease. Airgas
believes that the terms of the lease are no less favorable than could have been
obtained in arms-length transactions with unaffiliated third parties.

         In April 1995, Airgas made a $110,000 loan to William E. Sanford, Vice
President - Sales and Marketing, to assist in the payment of taxes incurred as a
result of Mr. Sanford's exchange of an interest

                                       78

in a subsidiary for Airgas' Common Stock. The loan had an annual interest rate
of 9%, and principal and interest were due and payable on demand. Mr. Sanford
repaid the principal amount in full plus interest of $7,975 in December 1995.

         In fiscal 1995, Mr. Knieling received a $250,000 contingent payment
from Airgas in connection with Airgas' acquisition of a company owned by Mr.
Knieling.

Airgas Common Stock

         Airgas has the authority to issue 200,000,000 shares of common stock,
         par value $.01 per share. At February 28, 1997, Airgas had outstanding
         68,130,470 shares of common stock.

                                       81
<PAGE>
 
         The following description of the Airgas Common Stock sets forth certain
general terms and provisions of the Airgas Common Stock. The statements below
describing the Airgas Common Stock are in all respects subject to and qualified
in their entirety by reference to the applicable provisions of Airgas's Amended
and Restated Certificate of Incorporation and Bylaws.

         Holders of the Airgas Common Stock will be entitled to receive
dividends when, as and if declared by the Board of Directors of Airgas, out of
assets legally available therefor. Upon any liquidation, dissolution or winding
up of Airgas, holders of Airgas Common Stock will be entitled to share equally
and ratably in any assets available for distribution to them, after payment or
provision for payment of the debts and other liabilities of the Company and the
preferential amounts owing with respect to any outstanding preferred stock. The
Airgas Common Stock possesses ordinary voting rights for the election of
director and in respect of other corporate matters, with each share entitling
the holder thereof to one vote. Holders of shares of Airgas Common Stock do not
have preemptive rights, which means they have no right to acquire any additional
shares of Airgas Common Stock that may be issued by Airgas at a subsequent date.
The Airgas Common Stock will, when issued, be fully paid and nonassessable and
will not be subject to preemptive or similar rights.

         As a corporation under the laws of the State of Delaware, Airgas is
subject to Section 203 of the DGCL, which restricts certain business
combinations between Airgas and an "interested stockholder" (in general, a
stockholder owning 15% or more of Airgas's outstanding voting stock) or such
stockholder's affiliates or associates for a period of three years following the
date on which the stockholder becomes an "interested stockholder." The
restrictions do not apply if (i) prior to an interested stockholder becoming
such, the Board of Directors approves either the business combination or the
transaction in which the stockholder becomes an interested stockholder, (ii)
upon consummation of the transaction in which such stockholder becomes an
interested stockholder, such interested stockholder owns at least 85% of the
voting stock of Airgas outstanding at the time the transaction commenced
(excluding shares owned by certain employee stock ownership plans and persons
who are both directors and officers of Airgas), or (iii) on or subsequent to the
date an interested stockholder becomes such, the business combination is both
approved by the Board of Directors and authorized at an annual or special
meeting of Airgas's stockholders (and not by written consent) by the affirmative
vote of at least 662/3% of the outstanding voting stock not owned by the
interested stockholder. Airgas's Amended and Restated Certificate of
Incorporation also includes a provision requiring the affirmative vote of at
least 67% of the outstanding voting stock for certain business combinations
involving an interested stockholder, except under the circumstances provided
therein. for purposes of such provisions, an "interested stockholder" means
generally a stockholder owning 20% or more of the outstanding voting stock of
Airgas or an affiliate of Airgas that, at any time within the two year period
preceding the related business combination, held 20% of the outstanding voting
stock of Airgas. In addition, Airgas's Amended and Restated Certificate of
Incorporation requires the affirmative vote of a majority of the outstanding
shares of capital stock of Airgas for the purchase by Airgas of its equity
securities (as defined in such Amended and Restated Certificate of
Incorporation) from any interested stockholder (as defined in the preceding
sentence) who has beneficially owned such securities for less than a two year
period.

Airgas Preferred Stock

Airgas's Amended and Restated Certificate of Incorporation authorizes the
issuance of 20,000,000 shares of preferred stock ("Preferred Stock") with such
designations, rights and preferences as may be determined from time to time by
the Airgas Board. Accordingly, the Airgas Board is empowered,

                                       82
<PAGE>
 
without stockholder approval, to issue Preferred Stock with dividend,
liquidation, conversion, voting or other rights which could adversely affect the
voting power or other rights of the holders of the Airgas Common Stock. The
Preferred Stock could be utilized, under certain circumstances, as a method of
discouraging, delaying or preventing a change in control of Airgas. Airgas is
also authorized to issue 30,000 shares of Non-Voting Preferred Stock, none of
which are outstanding. If issued, holders of the Non-Voting Preferred Stock
would be entitled to annual, cumulative dividends of $6.00 per share for the
first four years and $8.00 per share thereafter. Although Airgas has no
commitments as of the date of this Proxy Statement/Prospectus to issue any
shares of Preferred Stock, there can be no assurance that Airgas will not do so
in the future.

Stock Purchase Rights
         
     On April 16, 1997, the Board of Directors of Airgas declared a dividend
distribution of one preferred stock purchase right (the "Rights") for each
outstanding share of Airgas Common Stock to stockholders of record at the close
of business on April 29, 1997.  Each Right entitles the registered holder to
purchase from Airgas one one-thousandth of a share of Series B Junior
Participating Preferred Stock, par value $.01 per share (the "Series B Preferred
Stock") (or in certain circumstances, cash, property, or other securities of
Airgas), at a purchase price of $100.00, subject to adjustment (the "Purchase
Price").  The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement"), dated as of April 1, 1997, between Airgas
and The Bank of New York, N.A., as Rights Agent (the "Rights Agent").      

     Initially, the Rights will not be exercisable and will be evidenced by the
certificates representing shares of Airgas Common Stock then outstanding, and no
separate Rights Certificates will be distributed.  The Rights will separate from
the Common Stock and become exercisable upon the earlier of (i) ten calendar
days following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired beneficial ownership of
15% (or 20% in the case of Peter McCausland or certain of his affiliates) or
more of the outstanding shares of Airgas Common Stock (the "Stock Acquisition
Date") or (ii) ten business days (or a later date as is determined by the Board
of Directors, or if there has been an Adverse Change of Control (as defined
below), by a majority of the continuing directors after the commencement of, or
first public announcement of an intention to commence, a tender offer or
exchange offer that would result in a person or group beneficially owning 15%
(or 20%, as the case may be) or more of such outstanding shares of Airgas Common
Stock.  The Rights will expire at the close of business on April 1, 2007, unless
earlier redeemed or exchanged by Airgas as described below.

     In the event that a person becomes an Acquiring Person, each holder of a
Right will thereafter have the right to receive, upon exercise, shares of Airgas
Common Stock (or in certain circumstances, cash property or other securities of
Airgas) having a value equal to two times the Purchase Price of the Right.
Notwithstanding the foregoing, following the occurrence of such an event or any
other Triggering Event (as defined below), all Rights that are, or (under
certain circumstances specified in the Rights Agreement) were, beneficially
owned by any Acquiring Person will be null and void.

     After the Stock Acquisition Date, in the event that (i) Airgas consolidates
or merges with any other person, and Airgas is not the surviving corporation,
(ii) any person engages in a share exchange, consolidation or merger with Airgas
where the outstanding shares of Airgas Common Stock are exchanged for
securities, cash or property of the person and Airgas is the surviving
corporation or (iii) 50% or more of the Airgas' assets or earning power is sold
or transferred, proper provision will be made so that each holder of  a Right
shall thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the Purchase Price of the
Right.  The events set forth in this paragraph and the preceding paragraph are
referred to as the "Triggering Events."
 
     The Purchase Price payable, and the number of shares of Airgas Common Stock
or other securities, cash or property issuable, upon exercise of the Rights are
subject to customary adjustment from time to time to prevent dilution in the
event of certain changes in the shares of Airgas Common Stock.

     In general, Airgas may redeem the Rights at a price of $.001 per Right
(subject to adjustment), at any time before the close of business on the tenth
calendar day following the Stock Acquisition Date.  However, if the
authorization to redeem the Rights occurs on or after the date of a change in a
majority of the Board of Directors as a result of a proxy or consent
solicitation and a person who was a participant in such solicitation has stated
that such person has taken or intends to take or become an Acquiring Person or
cause a Triggering Event (the existence of these circumstances being an "Adverse
Change of Control"), then the redemption of the Rights will require the approval
of a majority of the "continuing directors."  Immediately upon the action of the
Board of Directors ordering redemption of the Rights, the Rights will terminate
and the only right of the holders of Rights will be to receive the $.001
redemption price.

     After a person becomes an Acquiring Person (but before such Acquiring
Person owns 50% or more of Airgas' outstanding Airgas Common Stock), the Board
of Directors may exchange the then outstanding and exercisable Rights (other
than those owned by an Acquiring Person), for shares of Airgas Common Stock.

     The Rights have certain anti-takeover effects.  The Rights will cause
substantial dilution to a person or group that attempts to acquire Airgas
without conditioning the offer on a substantial number of Rights being acquired.
Accordingly, the existence of the Rights may deter certain acquirors from making
takeover proposals or tender offers.  However, the Rights help ensure that the
Airgas' stockholders receive fair and equal treatment in the event of any
proposed takeover of Airgas.  The execution of the Rights Agreement by Airgas is
not in response to any specific takeover threat or proposal, but is a precaution
taken to protect the rights of Airgas' stockholders.

         On August 1, 1988, the Airgas Board of Directors adopted a preferred
share purchase rights plan (the "1988 Plan") that entitled Airgas stockholders
to purchase from Airgas a unit consisting of one one-hundredth of a share of the
Series A Junior Participating Preferred Shares or a combination of securities
and assets of equivalent value, at a purchase price of $65.00 per Unit, subject
to adjustment. The 1988 Plan will expire in August 1998. In view of, among other
things, the impending expiration of the 1988 Plan, the Board adopted the new 
plan. Pending its expiration in 1998, the Board amended the 1988
Plan to provide that it will not take effect if the new plan is triggered.

                                      CIC

Business
             
         General. CIC is engaged in the production and distribution of liquid
         -------
carbon dioxide and solid carbon dioxide (dry ice) and the rental of carbon
dioxide equipment. CIC was incorporated in Florida in 1965, under the name
Florida Carbonic Manufacturing Company. In 1972, CIC changed its name to
Carbonic Industries Corporation. CIC's principal executive offices are located
at 3700 Crestwood Parkway, Suite 200, Duluth, Georgia 30136. Sales for CIC were
approximately $45 million, $42 million and $35 million in 1996, 1995 and 1994,
respectively. Sales of carbon dioxide (liquid carbon dioxide and dry ice)
represented 95% of total sales and 88% of operating income in 1995 and 1996,
respectively.      

         On a volume basis, CIC believes it is one of the four largest suppliers
in the United States of carbon dioxide in its various forms. The other major
carbon dioxide producers in the United States are the BOC Group, Praxair, Inc.
and Air Liquide. Similar to other merchant carbon dioxide producers, CIC's
customers use carbon dioxide in refrigeration, freezing, food processing and
beverage carbonation, chemical processing, crude oil recovery, metal fabrication
and agricultural fumigations. CIC acquires carbon dioxide from natural sources
and as a byproduct of various manufacturing processes, and then refines and
processes it into liquid and dry ice forms before marketing and selling it in
bulk quantities. CIC markets and sells carbon dioxide products in 19 states,
principally located east of the Mississippi River.

         CIC rents liquid carbon dioxide storage tanks and related applications
equipment to its customers as an ancillary service to its carbon dioxide supply
business. Revenues from the equipment rental business represent less than three
percent of CIC's total revenues.

         CIC is a party to an agreement dated January 14, 1994 with Arcadian LCD
Corporation ("Arcadian") forming a 50%/50% joint venture known as AC Industries.
AC Industries operates a single 500 ton per day plant which produces liquefied
carbon dioxide from unpurified carbon dioxide gas purchased from an affiliate of
Arcadian. A 650 ton per day expansion project is underway and scheduled for
completion in July 1997. CIC markets all the inventory produced by AC Industries
under a marketing agreement. AC Industries is managed and operated by employees
of CIC and Arcadian under various expense reimbursement agreements.

         Suppliers.  Success in the carbon dioxide business is dependent to a 
         ---------
significant extent on access to adequate and reliable supplies of the gas. CIC
currently obtains unprocessed carbon dioxide from five suppliers, two of which
(AC Industries and Airgas' carbon dioxide facility located in Jackson,

Merger." CIC has long-term supply contracts with each of its suppliers that
require the purchase of specified minimum amounts of carbon dioxide, but
generally these contracts do not obligate the suppliers to continue to produce
carbon dioxide or to supply specified minimum quantities to CIC. Generally CIC
purchases carbon dioxide from these suppliers at fixed prices with provisions
for cost escalation. These contractual provisions have not historically had a
material adverse affect on CIC's ability to maintain its sources of supply. CIC
believes it has good relationships with each of its suppliers and that its
access to supplies of carbon dioxide is secure.

         Customers. In 1996, fifteen customers accounted for approximately 22%
         ---------
of CIC's revenues. Although the loss of any one of these customers would have an
adverse impact on CIC's business in the short term, CIC believes it would be
able to replace the lost business fairly quickly and that it would not suffer
any long term material adverse impact.

         Facilities and Equipment. In addition to its principal executive
         ------------------------
offices, CIC operates nine production facilities and 17 distribution and
warehousing facilities, primarily in the eastern United States. AC Industries
operates another production facility in Georgia. Generally CIC owns the
buildings and equipment that are associated with its production facilities, and
has a lease with the source of carbon dioxide for land adjacent to the source to
house the production facility. The lease typically runs for the term of the
supply contract and is for a nominal amount of rent. Distribution and
warehousing facilities are owned or leased on short-term standard business
leases which CIC believes can generally be replaced with similar facilities, if
necessary, without any material adverse effect on CIC. CIC has operating leases
for the use of railroad tank cars, tractors and trucks with terms that range
from three to ten years.

         Employees.  CIC employed approximately 270 employees at March 1, 1997. 
         ---------
The employees are not subject to a collective bargaining agreement. Management
of CIC considers its relations with its employees to be good.

        CIC Management's Discussion and Analysis of Financial Condition and
        Results of Operations

        Financial Review Overview - Fiscal Year Ended December 31, 1996

                CIC's financial results for the year ended December 31, 1996
        reflect substantial growth compared to 1995. Net sales of approximately
        $45.2 million, net earnings of $2.1 million and earnings per share of
        $2.48 represent increases over 1995 of 8%, 20%, and 20%, respectively.
        During 1996, carbon dioxide sales increased 9% compared to 1995.

                CIC entered into an agreement in February 1997 to modify its
        long term supply contract with Arcadian LCD Corporation. Under the
        agreement, AC Industries has agreed to construct a plant addition at its
        facility that is expected to begin production in fiscal year 1997. This
        long term supply agreement will provide for additional carbon dioxide
        sales by CIC.

                Additional railcars were received during the year ended December
        31, 1996, bringing the fleet to 162. The total fleet of liquid carbon
        dioxide transport trailers has increased to 54 with the addition of 20
        new units. This additional capacity will ensure a continued supply to
        the current customer base and allow for growth with the AC Industries
        expansion.

                Historically, operations have generated sufficient cash flow to
        finance CIC's operating activities. CIC has financed major production
        facility expansions with long-term debt borrowings. In 1996, CIC
        incurred additional debt of $2.5 million related to purchases of liquid
        carbon dioxide transport trailers and a storage receiver. In addition,
        CIC has made a capital contribution of $2 million to fund the planned
        production plant expansion at AC Industries. In February 1997, CIC made
        an additional capital contribution of $3 million for this plant
        expansion.

                At December 31, 1996, CIC had unused availability of $1.5
        million on a secured line of credit. CIC's debt to equity ratio at
        December 31, 1996 was 57% compared to 56.9% at December 31, 1995.

</TABLE> 

         For the year ended December 31, 1996, carbon dioxide sales increased
9%. The increase in sales was primarily attributable to the growth in the
customer base.

         Sales of equipment and rental revenue decreased 7%. This decrease was
attributable to a decline in rental and service revenue associated with renting
and servicing equipment.

         The increase in gross profit of approximately $1.8 million was
attributable to the increase in sales revenue. Partially offsetting this was the
additional cost associated with the increase in railcar lease commitments. Gross
profit as a percentage to sales for the year ended December 31, 1996 remained at
44% compared to 1995.

         Distribution, selling, and general and administrative expenses
decreased to 36% of sales for the year ended December 31, 1996 compared to 37%
in 1995. Lower operating costs as a percent to sales were achieved as a result
of sales growth which did not increase operating costs proportionately.
Offsetting these improvements were the increase in distribution cost as a result
of the purchase of additional liquid carbon dioxide transport trailers.

         Operating income increased 32% for the year ended December 31, 1996
compared to 1995:

         Carbon dioxide operating income as a percentage of carbon dioxide net
sales increased to 7.4% for the year ended December 31, 1996 compared to 5.7%
for 1995. The increase in carbon dioxide operating income in 1996 was a result
of the increase in the sales base while replacing lower gross margin accounts
with higher gross margin accounts.

         Equipment sales and rental operating income decreased as a percentage
of net equipment sales and rental to 18% for the year ended December 31, 1996
compared to 19.2% for 1995. The decrease was attributable to the decrease in
service order income partially offset by higher margins on the sale of
equipment.

         Interest expense decreased $125 thousand in 1996 compared to 1995
primarily as a result of converting debt associated with plant expansion to term
financing, partially offset by the increase in debt for capital expenditure
purchases.

         Equity in earnings of AC Industries decreased to $745 thousand for the
year ended December 31, 1996 from $843 thousand in 1995. The reduction
in earnings in 1996 resulted from a scheduled, temporary shutdown for routine
maintenance by the carbon dioxide gas supplier to AC Industries. Equity in
earnings of AC Industries represented 20% of pre-tax earnings in 1996 compared
to 28% in 1995.

         Income tax expense represented 43% of pre-tax earnings for the year
ended December 31, 1996 compared to 42% in 1995.

         Net earnings increased 20% to $2.1 million or $2.48 per share in 1996
from $1.8 million or $2.07 per share in 1995. After tax cash flow (net earnings
plus depreciation, amortization, deferred income taxes, and distribution from AC
Industries, less earnings from AC Industries) increased 5% to $5.2 million in
1996 from $5.0 million in 1995.

Financial Review Overview - Fiscal Year Ended December 31, 1995

         CIC's financial results for the year ended December 31, 1995 reflect
substantial growth compared to 1994. Net sales of approximately $42 million, net
earnings of $1.8 million and earnings per share of $2.07 represent increases
over 1994 of 21%, 34% and 34%, respectively. Attainment of the 1995 results were
largely attributable to the availability of liquid carbon dioxide for the first
full fiscal year from AC Industries and also the general shortage of supply
within the carbon dioxide industry. AC Industries was created on January 14,
1994 with initial liquid carbon dioxide production beginning June 30, 1994.
During 1995, carbon dioxide sales increased 22% compared to the prior year.

         During 1995, production plant modifications were in progress in several
locations, for the purpose of improving production capacity at such locations:
the Jacksonville, Florida plant was rebuilt, increasing CIC's dry ice production
at that location to 4.75 tons per hour; the Star, Mississippi production plant
and the Augusta, Georgia plant were both modified to increase condensing
capacity. In addition, additional railcars were ordered, to bring the fleet to
162, and the total fleet of liquid carbon dioxide transport trailers was
increased to 54, with the addition of 20 new units on order.

         Historically, operations have generated sufficient cash flow to finance
CIC's operating activities. CIC has financed major production facility
expansions with long-term debt borrowings. In 1995, CIC incurred additional debt
of $4.3 million related to the construction of the Augusta, Georgia dry ice
production facility and the investment in AC Industries. CIC received a
commitment letter for $6.6 million for the financing of 20 liquid carbon dioxide
transport trailers and a production plant expansion at AC Industries during the
year ended December 31, 1995.

         At December 31, 1995, CIC had unused availability of $1.5 million on a
secured line of credit. CIC's debt to equity ratio at December 31, 1995
decreased to 56.4% compared to 84.2% in the prior year.

         For year ended December 31, 1995, carbon dioxide sales increased
approximately $7 million, or 22%. The increase in carbon dioxide sales was
primarily a result of increased carbon dioxide supply from AC Industries
production facility.

         Sales of equipment and rental revenue increased 13%. This increase was
attributable to an 18% increase in equipment sales and a 63% increase in service
revenue associated with renting and selling equipment.

         The increase in gross profit of approximately $3.1 million was
attributable to the increase in sales revenue. CIC was able to improve its cost
of production for 1995 compared to the prior year due to the long term supply
contract with AC Industries. Partially offsetting these savings was the
additional cost associated with the increase in railcar lease commitments. Gross
profit as a percentage of sales remained at 44% for December 31, 1995 compared
to the prior year.

         Distribution, selling and general and administrative expenses remained
at 37% of sales for the year ended December 31, 1995 compared to December 31,
1994. CIC increased the volume of carbon dioxide distributed by 36% for the year
ended December 31, 1995 compared to the prior year. Lower operating costs as a
percent to sales were achieved as a result of sales growth which did not
increase operating costs proportionately. Offsetting these improvements were
insurance adjustments for audits, retrospective premiums and losses absorbed by
CIC through deductibles and self-insurance.

         Operating income increased 13% in 1995 compared to 1994:

         Carbon dioxide operating income as a percentage of net carbon dioxide
sales decreased to 5.7% for the year ended December 31, 1995 as compared to 6.3%
for the prior year. The decrease in carbon dioxide operating income in 1995 was
a result of the increase in operating lease commitments of railcars and tractors
to support the growth in the sales base.

         Equipment sales and rental operating income increased as a percentage
of net equipment sales and rental to 19.2% for the year ended December 31, 1995
compared to 16.5% for the prior year. The increase was attributable to the lower
cost of maintaining rental equipment partially offset by lower margins on sale
of equipment.

         Interest expense increased $57 thousand in 1995 compared to 1994
primarily as a result of the additional debt associated with production plant
expansions.

         Equity in earnings of AC Industries increased to $843 thousand in 1995
from $336 in 1994. AC Industries began initial production on June 30, 1994.
Equity in earnings of AC Industries represented 27.6% of pre-tax earnings in
1995 compared to 14.2% in the prior year.

         Income tax expense represented 42% of pre-tax earnings in 1995 compared
to 43.8% in 1994. The decrease in effective income tax rate was primarily due to
the impact of temporary differences between the amounts used for financial
reporting purposes and such amounts recognized for tax purposes.

         Net earnings increased 34% to $1.8 million or $2.07 per share in 1995
from $1.3 million or $1.55 per share in 1994. After tax cash flow (net earnings
plus depreciation, amortization, deferred income taxes, and distribution from AC
Industries, less earnings from AC Industries) increased 19% to $5.0 million in
1995 from $4.2 million in 1994.

</TABLE> 

         In 1994, carbon dioxide sales increased approximately $4.3 million, or
15%. The increase in sales was primarily due to the increase in the availability
of carbon dioxide supply for six months in 1994 from the start-up of AC
Industries production beginning June 30, 1994.

         Sales of equipment and rental revenue increased 21%. This increase was
due to a 97% increase in equipment sales and a 56% increase in service revenue
associated with renting and selling equipment.

         Compared to 1993, gross profit increased approximately $2.5 million.
The gross profit on carbon dioxide increased from 44% to 46% due to the
availability of liquid carbon dioxide supply from AC Industries. Gross profit as
a percentage to sales increased from 43% to 44% for the year ending December 31,
1994.

         Distribution, selling, and general and administrative expenses as a
percentage of sales decreased to 37% compared to 39% for the prior year. This
reduction is primarily due to spreading certain operating costs that are
relatively fixed over a larger sales base.

         Carbon dioxide operating income as a percentage of net carbon dioxide
sales increased to 6.3% compared to 3.1% for the prior year. The increase in
gross profit in 1994 was a result of the increase in sales base and a lower cost
of sales resulting from the availability of liquid carbon dioxide from AC
Industries production plant.

         Equipment sales and rental operating income increased as a percentage
of net equipment sales and rental sales to 16.5% compared to 15.3% for the prior
year. The increase was attributable to an increase in sales volume partially
offset by lower margins on those sales.

         Interest expense increased $136 thousand primarily as a result of the
increase in outstanding debt associated with production plant expansions.

         Equity in earnings of AC Industries; contributed an increase of $336
thousand to net earnings over 1993. AC Industries began initial production on
June 30, 1994. Equity in earnings of AC Industries represented 14.2% of pre-tax
earnings for 1994.

         Income tax expense represented 43.8% of pre-tax earnings in 1994
compared to 52.3% in 1993. The decrease in effective income tax rate was
primarily due to the impact of temporary differences between the amounts used
for financial reporting purposes and such amounts recognized for tax purposes.

         Net earnings increased substantially from the prior year to $1.3
million or $1.55 per share in 1994 from $15 thousand or $.02 per share in 1993.
After tax cash flow (net earnings plus depreciation, amortization, deferred
income taxes, and distribution from Joint Venture, less earnings from Joint
Venture) increased 48.8% to $4.2 million from $2.8 million in 1993.

Liquidity and Capital Resources

         CIC has primarily financed its operations and capital expenditures with
funds provided by operating activities and with borrowings.
    
         Cash flows from operating activities totaled $5.1 million for the year
ended December 31, 1996, after adding back depreciation and amortization
totaling $3.1 million. Cash flow from working capital components increased $637
thousand primarily as a result of a decrease in trade receivables. Days-sales
outstanding had decreased to 36 days as of December 31, 1996 compared to 45 days
for 1995.     

                                       91
<PAGE>
 
         Cash used in investing activities totaled $5.2 million for the year
ended December 31, 1996 which was primarily comprised of $4.0 million
for capital expenditures and contribution of capital to AC Industries of $2.0
million, offset by a $700 thousand distribution from AC Industries.

         CIC's use of capital expenditures beyond maintenance capital
expenditures was to invest in vehicles and equipment to support the growth in
the sales base. CIC estimates that its maintenance capital expenditures are
approximately 5% of net sales. CIC considers the replacement of existing capital
assets to be maintenance capital expenditures.

         Financing activities provided cash of $460 thousand for the year ended
December 31, 1996 with total debt outstanding increasing by $888 thousand from
December 31, 1995. CIC paid $428 thousand in dividends in 1996 and 1995. The CIC
Board of Directors declared a dividend in November 1996 that was paid on January
2, 1997. The total amount of the dividend was $642 thousand.


         CIC has a secured line of credit with a commercial bank for $1.5
million, which was increased to $3 million in January 1997. At December 31,
1996, CIC had no outstanding borrowings under this line. CIC intends to borrow
under this facility to finance the construction of the AC Industries plant
expansion until permanent financing is obtained. CIC has received a commitment
letter from a commercial bank with respect to such financing. On February 21,
1997, CIC borrowed $2 million from a commercial bank under a 90-day single
disbursement note, which is due on May 22, 1997. CIC intends to use the proceeds
from this note to fund short-term cash flow needs until permanent financing has
been obtained for capital expenditure requirements.

         At December 31, 1996 the effective interest rate related to
outstanding borrowings under all credit agreements was approximately 10.1%.
CIC's loan agreements contain covenants which include the maintenance of a
minimum equity level, minimum working capital, maintenance of certain financial
ratios, restrictions on additional borrowings and operating lease commitments,
and limitations on dividends.

         CIC will continue to look for opportunities to expand its product
supply in order to expand its sales base. CIC expects to fund these capital
expenditure requirements primarily through the use of cash flow and debt.

Forward-looking Statements

         The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain information included in this
Proxy Statement/Prospectus contains statements regarding CIC that are
forward-looking, such as statements relating to business development activities,
plant expansion, future capital expenditures, financing sources and availability
and the effects of regulation and competition. Such forward-looking information
involves important risks and uncertainties that could significantly affect
anticipated results in the future and, accordingly, such results may differ from
those expressed in any forward-looking statements. These risks and uncertainties
include, but are not limited to, uncertainties affecting the carbon dioxide
business generally (such as the effects of competition from other distributors
and producers, variations in sources and reliability of supply and changes in
pricing), possible environmental liabilities, risks relating to the
self-insurance of certain aspects of CIC's business, risks relating to leverage
and debt service and the effects of changes in the economy on both a national
and international basis.

New Accounting Pronouncements

         In the first quarter of fiscal 1996, CIC adopted SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of." The statement requires the recognition of an impairment loss
for an asset held for use when the estimate of undiscounted future cash flows
expected to

                                       92
<PAGE>
 
be generated by the asset is less than its carrying amount. Measurement of the
impairment loss is based on fair value of the asset. Management believes that
the adoption of this statement did not have a material impact on earnings,
financial condition or liquidity of CIC.

         CIC accounts for stock options according to the provisions of
Accounting Principles Board Opinion 25 (APB 25), "Accounting for Stock Issued to
Employees." In October 1995, the Financial Accounting Standards Board issued
SFAS Statement No. 123, "Accounting for Stock-Based Compensation." The new
standard defines a fair value method of accounting for stock options and similar
equity instruments. Companies may elect to continue to use existing accounting
rules or adopt the fair value method for expense recognition. Companies that
elect to continue to use existing accounting rules are required to provide pro
forma disclosures of net income and earnings per share assuming the fair value
method was adopted. CIC has elected to continue to use existing accounting
rules. Accordingly, CIC will present the required pro forma disclosure
provisions for its fiscal year ending December 31, 1996. As CIC will continue to
account for stock-based compensation using the intrinsic value method, this
statement will not have a material impact on earnings, financial condition or
liquidity of CIC.

         In October 1996, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 96-1, 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. Management believes that the adoption of this
statement will not have a material impact on earnings, financial condition or
liquidity of CIC.

                         INDEPENDENT AUDITORS' REPORT


The Board of Directors
Airgas, Inc.:

         We have audited the consolidated financial statements of Airgas, Inc.
and subsidiaries as listed in the accompanying index. In connection with our
audits of the consolidated financial statements, we also have audited the
financial statement schedule as listed in the accompanying index. These
consolidated financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Airgas, Inc.
and subsidiaries as of March 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended March 31, 1996, in conformity with generally accepted accounting
principles. Also in our opinion, the related financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
thereon.

                         AIRGAS, INC. AND SUBSIDIARIES

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a)      Basis of Presentation

The consolidated financial statements include the accounts of Airgas, Inc. and
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 over the Company's share of their net assets at the acquisition date
is being amortized over 20 to 40 years. Significant intercompany accounts and
transactions are eliminated.

         The Company has made estimates and assumptions relating to the
reporting of assets and liabilities and disclosure of contingent assets and
liabilities to prepare these statements in conformity with generally accepted
accounting principles. Actual results could differ from those estimates.

(b)      Inventories

         Inventories are stated at the lower of cost or market with cost for
approximately 81% and 77% percent of the inventories at March 31, 1996 and 1995,
respectively, determined by the first-in, first-out (FIFO) method. Cost for the
remainder of inventories was determined using the last-in, first-out (LIFO)
method. 

(c)      Plant and Equipment

         Plant and equipment are stated at cost. Depreciation is provided on the
straight-line basis over the estimated useful lives of the related assets.

         Effective April 1, 1993, the Company changed its estimate of the useful
lives of its acetylene and high pressure cylinders from 20 to 30 years. This
change was made to better reflect the estimated periods during which these
assets will remain in service. The change had the effect of reducing
depreciation expense in 1994 by approximately $3.1 million and increasing net
earnings by $1.9 million or $.03 per share.

         The Company changed the estimated useful life of cylinders as a result
of thorough studies and analyses. The studies considered technological advances
in cylinders, empirical data obtained from cylinder manufacturers and other
industry experts and experience gained from the Company's maintenance of a
cylinder population of approximately two million cylinders.

         In the first quarter of fiscal 1997, the Company will adopt SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." The statement requires the recognition of an
impairment loss for an asset held for use when the estimate of undiscounted
future cash flows expected to be generated by the asset is less than its
carrying amount. Measurement of the impairment loss is based on fair value of
the asset. Management believes that the adoption of this statement will not have
a material impact on earnings, financial condition or liquidity of the Company.

(d)      Other Assets

         Costs related to the acquisition of long-term debt are deferred and
amortized over the term of the related debt. Costs and payments pursuant to
noncompetition arrangements entered into in connection with business
acquisitions are amortized over the terms of the arrangements which are
principally over 5 years. On an ongoing basis, management reviews the valuation
and amortization of intangible assets.

(e)      Goodwill

         Goodwill represents costs in excess of net assets of businesses
acquired and is amortized on a straight-line basis over the expected periods to
be benefited, which currently ranges from 20 to 40 years. The Company assesses
the recoverability of this intangible asset by determining whether the
amortization of the goodwill balance over its remaining life can be recovered
through projected undiscounted future cash flows.

(f)      Income Taxes

         Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

(g)      Foreign Currency Translation

         The functional currency of the Company's foreign operations is the
applicable local currency. The translation of foreign currencies into U.S.
dollars is performed for balance sheet accounts using current exchange rates in
effect at the balance sheet date and for revenue and expense accounts using
average exchange rates during each reporting period. The gains or losses, net of
applicable deferred income taxes, resulting from such translations are included
in stockholders' equity. Gains and losses arising from foreign currency
transactions are reflected in the consolidated statements of earnings as
incurred.

(h)      Concentrations of Credit Risk

         Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of trade receivables.
Concentrations of credit risk are limited due to the Company's large number of
customers and their dispersion across many industries. Credit terms granted to
customers are generally net 30 days.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(i)  Revenue Recognition

     Sales are recorded upon shipment to the customer.

(j)  Financial Instruments

     In hedging interest rate exposure, the Company enters into interest rate
swap agreements. These instruments are not entered into for trading purposes and
the Company has the ability and intent to hold these instruments to maturity.
The Company only uses non-leveraged instruments. When interest rates change, the
difference to be paid or received is accrued and recognized as interest expense
over the life of the agreement. The fair values of the Company's financial
instruments are estimated based on quoted market prices for the same or similar
issues.

     The carrying amounts for accounts receivable, accounts payable and current
portion of long-term debt approximate fair value because of the short-term
maturity of these financial instruments.

(k)  Reclassification

     Certain reclassifications have been made in previously issued financial
statements to conform to the current presentation.

(2)  ACQUISITIONS

     The Company has acquired businesses primarily engaged in the distribution
of industrial, medical and specialty gases and related equipment . 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.

     1996 - During 1996, the Company purchased 42 businesses. The largest of
these acquisitions and their effective dates included Tech-Weld, Inc. (April 3,
1995), Trinity Welding Supply, Inc. (May 1, 1995), Red-D-Arc, Limited (June 29,
1995), Capital Welding Supply, Inc. (August 1, 1996), Langdon Oxygen Company
(October 5, 1995), Acetylene Gas Company (January 1, 1996), Iatech Sales Co.
(January 1, 1996), Welders Equipment Company (February 1, 1996) and Braun
Welding Supply, Inc. (March 1, 1996). The aggregate purchase price for these
acquisitions amounted to approximately $164 million. The purchase price for the
remaining 33 businesses amounted to approximately $73 million.

     1995--During 1995, the Company purchased 25 businesses. The largest of
these acquisitions and their effective dates included The Jimmie Jones Company
(August 1, 1994) and Post Welding Supply (November 1, 1994). The aggregate
purchase price for these acquisitions amounted to approximately $83 million. The
purchase price for the remaining 23 businesses amounted to approximately $44
million.

         Also, as discussed in note 19, the Company has accounted for the
acquisition of subsidiary minority interests in 1996, 1995 and 1994 using the
purchase method of accounting.

         In connection with certain acquisitions, the Company is required to
make future payments to sellers based on future earnings of the acquired
business in excess of predetermined amounts. Such payments, if any, are
capitalized as an additional cost of the acquisition. Amounts payable under
contingent payment terms continue through 1997 and are limited to $2.1 million.
To-date, the Company has made aggregate payments of $1.1 million under these
contingent terms. In addition, certain other acquisitions require the issuance
of Airgas common stock if the Airgas common stock price at certain dates during
1999 is less than a previously established price.

         The purchase price for business acquisitions and minority interests
were allocated to the assets acquired and liabilities assumed based on their
estimated fair values. Costs in excess of net assets acquired (goodwill) for
1996, 1995 and 1994 amounted to $81.3 million, $40.8 million and $9.9 million,
respectively.

         The following presents unaudited estimated pro forma operating results
as if the 1996 and 1995 acquisitions had been consummated on April 1, 1994.
These pro forma results have been prepared for comparative purposes only and do
not purport to be indicative of what would have occurred had the acquisitions
been made as of April 1, 1994 or of results which may occur in the future.

     During 1996, the Company amended and increased its unsecured revolving
credit facility with various commercial banks from $250 million to $375 million,
and converted the facility to a five-year revolver maturing on August 10, 2000.
The revolving credit facility also provides for the issuance of letters of
credit up to $150 million. Under the terms of the revolving credit facility,
interest is payable quarterly. At March 31, 1996, $66 million of money market
based borrowings were outstanding under the revolving credit facility with
effective rates of 5.57%. At March 31, 1996, $105 million of Libor based
borrowings were outstanding under the revolving credit facility with effective
rates of 5.98%. At the Company's option, borrowings under the revolving credit
facility may be prime based, Libor based or Certificate of Deposit based in each
case plus an applicable margin.

     The Company has an additional $100 million unsecured line of credit with a
group of commercial banks which matures in July 1997 and provides for borrowings
at the Libor rate plus an applicable margin ($100 million outstanding at 5.76%
as of March 31, 1996). The Company intends to terminate its $100 million
facility in conjunction with an anticipated increase in the Company's $375
million revolving credit facility in September 1996, which will have terms and
conditions similar to its existing $375 million facility.

     The Company has a CDN $50 million Canadian credit facility ($37 million
U.S.) with various commercial banks which matures on November 14, 1998. At March
31, 1996, the Company had approximately CDN $33 million ($24 million U.S.) in
borrowings outstanding under the facility, resulting in unused availability
under the facility of approximately CDN $17 million ($13 million U.S.).

     The Company also has unsecured line of credit agreements with various
commercial banks. At March 31, 1996, these agreements totaled $60 million, under
which the Company had aggregate outstanding borrowings of $19 million, at 5.61%.

     Senior subordinated notes with an original face value aggregating $55
million require semi-annual interest payments at 11.375%. Equal annual principal
payments of $4.3 million for $12.8 million of the senior subordinated notes
continue through August 1998 and equal annual principal payments of $3.6 million
for $7.2 million of the senior subordinated notes continue through July 1997.

     Acquisition notes represent notes issued to sellers of businesses acquired
and are repayable in periodic installments including interest at an average rate
of 7.5%. Some acquisition notes require balloon payments which are included in
the aggregate maturity schedule.

     Industrial development revenue bonds have variable interest rates ranging
from 60% to 75% of the prime rate. The bonds mature at various dates between
1996 and 2006. Certain bonds are redeemable at the option of the issuer. The
bonds are secured by mortgages on certain plant and equipment.

     Certain of the Company's credit facility agreements contain restrictive
covenants which include the maintenance of a minimum equity level, maintenance
of certain financial ratios and restrictions on additional borrowings and
dividend payments.

The fair value of long term debt as of March 31, 1996 was approximately $400
million based on current rates offered to the Company by financial institutions
for similar type instruments.

(b) Swap Agreements

     In managing interest rate exposure, principally under the Company's
floating rate revolving credit facilities, the Company has entered into 18
interest rate swap agreements during the period from June 1992 through March 31,
1996, including two forward starting swaps. The interest rate swap agreements
are with major financial institutions having a total notional principal amount
of $224 million at March 31, 1996.

     Approximately $205 million of the swap agreements require fixed interest
payments based on an average effective rate of 6.53% for remaining periods
ranging between 1 and 8 years. The remaining $19 million of swap agreements
require floating rates (5.53% at March 31, 1996). The effect of the swap
agreements was to increase interest expense $1.3 million and $1.2 million in
1996 and 1995, respectively. 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 March 31, 1996, approximately $23 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 fair market value of these swaps was $2.9 million below
their carry value at March 31, 1996.

(9) STOCKHOLDERS' EQUITY

(a) Common Stock

     On March 22, 1996, the Company's Board of Directors declared a two-for-one
stock split to stockholders of record on April 1, 1996, payable on April 15,
1996. Stock options and other rights to acquire the Company's common stock
reflect the split. The Statements of Stockholders' Equity have been restated to
account for the stock split as if it had occurred on April 1, 1993. All
references to the number of shares, except shares authorized, reflect the stock
split.

(b) Preferred Stock and Redeemable Preferred Stock

     The Company is authorized to issue 20 million shares of preferred stock. At
March 31, 1996 and 1995, no shares were outstanding. The preferred stock may be
issued from time to time by the Board of Directors in one or more series, and
the Board of Directors is authorized to fix the dividend rights and terms,
conversion rights, voting rights, rights and terms of redemption, liquidation
preferences, and any other rights, preferences, privileges and restrictions of
any series of Preferred Stock, and the number of shares constituting each such
series and designation thereof.

     Additionally, the Company is authorized to issue 30,000 shares of
redeemable preferred stock. At March 31, 1996 and 1995, no shares were
outstanding.

(c) Treasury Stock

     The Company's Board has approved a four million share common stock
repurchase program. Through March 31, 1996, the Company purchased 2.4 million
shares of the Company's common stock at an aggregate cost of $28.9 million. The
impact of the stock repurchases on earnings per share amounts was immaterial for
1996. The future purchase of common stock is dependent on prevailing market
conditions.

(d) Stock Options

     The Company has a stock option plan for officers and key employees and has
reserved 14,080,000 shares under this plan. Options are granted on terms and


                                     F-18

(e) Stock Purchase Warrants

     The Company and the Chairman of the Company were parties to a Stock and
Warrant Issuance Agreement, as amended (the "Warrant Agreement"), which was
entered into in connection with the Company's acquisition of US Airgas, Inc., of
which the Chairman was the majority shareholder, in May 1986. Pursuant to the
Warrant Agreement, the Chairman received warrants to purchase a total of
14,127,432 shares of the Company's common stock. Subsequent to the grant dates,


                                     F-19

(f) Shareholder Rights Plan

     Under the terms of a Shareholder Rights Plan, preferred share purchase
rights were distributed during 1988 as a dividend at the rate of one right for
each common share. The number of rights outstanding is subject to adjustment
under certain circumstances and all rights expire on August 1, 1998. The rights
are not exercisable until a person or entity acquires twenty percent of the
Company's common stock. Each right will entitle the holder to buy $16.25 worth
of the Company's common stock at an exercise price of $8.13.

(g)  Stock-Based Compensation

     The Company accounts for stock options according to the provisions of
Accounting Principles Board Opinion 25 (APB 25), "Accounting for Stock Issued to
Employees." In October 1995, the Financial Accounting Standards Board issued
FASB Statement No. 123, "Accounting for Stock-Based Compensation." The new
standard defines a fair value method of accounting for stock options and similar
equity instruments. Companies may elect to continue to use existing accounting
rules or adopt the fair value method for expense recognition. Companies that
elect to continue to use existing accounting rules will be required to provide
pro-forma disclosures of net income and earnings per share assuming the fair
value method was adopted. The Company will elect to continue to use existing
accounting rules. The new statement is effective for fiscal years beginning
after December 15, 1995. Accordingly, the Company will adopt the provisions in
the first quarter of fiscal 1997 and present the required pro-forma disclosure
provisions for its fiscal year ending March 31, 1997. As the Company will
continue to account for stock-based compensation using the intrinsic value
method, this statement will not have a material impact on earnings, financial
condition or liquidity of the Company.

         The Company has recorded tax benefits amounting to $7.6 million, $1.9
million and $3.6 million in 1996, 1995 and 1994, respectively, resulting from
the exercise of stock options and warrants. This benefit has been recorded in
capital in excess of par value.

         The Internal Revenue Service is currently conducting an examination of
the Company's federal income tax returns for the years ended March 31, 1993 and
1994. Management believes that the results of this examination will not have a
material effect on the Company's earnings, financial condition, or liquidity.

(14) BENEFIT PLANS

(a) Pension and Profit Sharing Plans

         The Company has a defined contribution 401(k) plan covering
substantially all full-time employees. Under the terms of the plan, the Company
makes matching contributions up to two percent of participants' wages plus
additional discretionary profit sharing contributions based upon the
profitability of the Company. Amounts expensed under the plan for 1996, 1995 and
1994 were $5.1 million, $4.7 million and $3.3 million, respectively.

         During 1993, the Company authorized termination of two defined benefit
pension plans effective December 31, 1992. At December 31, 1995, the plans'
projected benefit obligations approximate the plans' net assets available for
benefits. The settlement of the vested benefit obligations by the purchase of


                                     F-23
<PAGE>
 
nonparticipating annuity contracts or lump-sum payments for covered employees is
not expected to result in a significant gain or loss.

         Certain subsidiaries of the Company participate in multi-employer
pension plans which provide defined benefits to union employees. Contributions
are made to the plans in accordance with negotiated labor contracts. The Company
has not taken any action to terminate or withdraw from these plans. Management
believes that the Company's liability, if any, for multi-employer plan
withdrawal liability will not have a material effect on the Company's financial
position, results of operations, or liquidity. Amounts expensed under these
plans for 1996, 1995 and 1994 were $482 thousand, $418 thousand and $227
thousand, respectively.

(b) Employee Stock Purchase Plan

         The Company has established an employee stock purchase plan (the
"Plan") to encourage and assist employees to acquire an equity interest in the
Company. The Plan is authorized to issue 2 million shares of common stock.
Generally, employees may elect to have 1 to 15 percent of their gross pay
withheld to buy Airgas, Inc. common stock at 85 to 95 percent of the market
value depending upon base salary levels. Market value under the Plan is either
the employees' enrollment date market value or the quarterly purchase date
market value, whichever is lower. An employee may lock-in a purchase price for
up to 27 months. The Plan is designed to comply with the requirements of section
423 of the Internal Revenue Code.

         Under the Plan, 368,194, 300,204 and 59,470 shares were issued at an
average purchase price of $9.22, $9.02 and $9.00 per share during 1996, 1995 and
1994, respectively.

(c) Other Employee Benefits

         The Company sponsors a multi-employer postretirement medical benefit
plan for certain employees of one subsidiary under a collective bargaining
agreement. In accordance with SFAS 106 "Employers Accounting for Postretirement
Benefits Other Than Pensions" and APB Opinion No. 16 "Business Combinations",
the postretirement benefit obligation was recorded at the acquisition date.

         The net postretirement benefit expense was $98 thousand and $88
thousand for the years ended March 31, 1996 and 1995, respectively. The
Company's unfunded accumulated postretirement benefit obligation was $896
thousand and $837 thousand at March 31, 1996, and 1995, respectively.

         In determining the accumulated postretirement benefit obligation, the
discount rate used to estimate the actuarial present value of other
postretirement benefits was 7.50% and 8.25% at March 31, 1996 and 1995,
respectively. The assumed rate of increase in the health care cost trend rate
for employees less than age 65 was 8.25% and 9.75% for March 31, 1996 and 1995,
declining gradually to 5.25% and 6.0%, respectively, over the next four years.
For employees 65 and older, the assumed rate of increase was 6.16% and 6.62% for
March 31, 1996 and 1995, declining gradually to 5.25% and 5.5%, respectively,
over the next four years. A 1% increase in the healthcare cost trend rate would
have increased net postretirement benefit expense approximately $18 thousand and
the APBO approximately $139 thousand at March 31, 1996.

ended March 31, 1996, 1995 and 1994, fees paid to the law firm totaled $754
thousand, $525 thousand, and $551 thousand, respectively.

         The Company is a party to a sales agency agreement for the sale of
carbon products with a company which is a greater than five percent stockholder
and a director of that company is also a former director of the Company. The
sales agency agreement expires in October 2003. During the years ended March 31,
1996, 1995 and 1994, the Company paid $685 thousand, $543 thousand and $515
thousand, respectively, under this agreement.

         A member of the Company's board of directors is the president of a
regional producer and distributor of industrial gases and related equipment in
the Southeastern United States. During the years ended March 31, 1996, 1995 and
1994, this company paid $987 thousand, $914 thousand and $1.1 million,
respectively, to a joint venture of the Company for the purchase of calcium
carbide. In addition, this company paid $604 thousand and $546 thousand to the
Company for other gas purchases in 1996 and 1995, respectively.

(16) LEASES

         The Company leases certain distribution facilities and equipment under
long-term operating leases with varying terms. Most leases contain renewal
options and in some instances, purchase options. Rentals under these long-term
leases (exclusive of real estate taxes, insurance, and other expenses payable
under the terms of the leases) for the years ended March 31, 1996, 1995 and
1994, amounted to $17.8 million, $14.5 million and $9.7 million, respectively.
Additionally, the Company leases certain operating facilities from employees of
the Company who were previous owners of businesses acquired at market rates.

         The Company entered into certain operating leases for real estate with
a trust established by a commercial bank. The trust is committed to purchase
real estate properties up to an aggregate amount of $25 million. The trust holds
title to the properties and leases the properties to the Company. The rental
payments are based on Libor plus an applicable margin and the cost of the
property acquired by the trust. The Company has entered into interest rate swap
agreements in a notional principal amount of $10 million to hedge the effects of
fluctuations in the Libor based rental rate. At the expiration of the leases in
1999, the Company has the option to purchase the real properties at fair value
or assist in the sale of the properties to a third party. The Company has
guaranteed a portion of the debt outstanding against these properties in the
event the proceeds of a sale are not sufficient to cover the trust's investment
in the properties. At March 31, 1996, the Company had a contingent guarantee of
approximately $7.6 million related to leased facilities.

         The Company has also entered into certain operating leases for
cylinders and bulk tanks. At the expiration of the leases in 1998, the Company
has the option to purchase equipment at a fixed price, assist in the sale of the
equipment to third parties, or renew the lease for a period of one year. The
Company has guaranteed a portion of the cost of the equipment in the event the
proceeds of a sale are not sufficient to cover the lessor's investment in the
equipment. At March 31, 1996, the Company had a contingent guarantee of $2.8
million related to equipment under such leases.

(17) COMMITMENTS AND CONTINGENCIES

         The Company is involved in various legal and regulatory 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 consolidated financial position, results of operations or liquidity.

(18) CASH FLOWS

         Cash paid for interest expense and income taxes was as follows:

         The total purchase price, fair value of assets acquired, cash paid and

         During 1996 and 1995, the Company entered into capital lease
obligations for approximately $912 thousand and $3.7 million, respectively.

         During 1995, the Company retired 3.8 million shares of treasury stock.

(19) MINORITY INTEREST IN SUBSIDIARIES

         Minority interests in subsidiaries represent the minority shareholders'
proportionate share of the equity and the results of operations of certain
subsidiaries. Under the terms of exchange rights agreements between the Company
and minority shareholders, the Company, under certain circumstances, may require
or permit exchange of the minority interests of a subsidiary for common stock of
the Company. The agreements provide the minority shareholders with the right to
exchange their subsidiary shares for common stock of the Company at certain
exchange dates designated by the Board of Directors. Each exchange will be based
on the fair value of the subsidiary's shares and the market price of the
Company's common stock as of a valuation date designated by the Board of
Directors.


                                     F-26
<PAGE>
 
         On August 31, 1995 and February 28, 1994, in connection with optional
exchanges, certain minority shareholders elected to exchange their minority
interests for an aggregate of 258,116 and 166,732 shares of common stock,
respectively. The market price of the Company's common stock on August 31, 1995
and February 28, 1994 was $13.75 and $10.438 per share, respectively . The
acquisition of the minority interests has been recorded using the purchase
method of accounting.

         During 1996, 1995 and 1994, the Company sold minority interests in
certain of its subsidiaries to employees based on the estimated fair market
value of the subsidiary shares. These sales of subsidiary shares were accounted
for as capital transactions and, therefore, no gain or loss was recorded.

(20) SUMMARY BY BUSINESS SEGMENT

         The Company, through its subsidiaries, is principally engaged in two
related businesses: 1) the distribution of industrial, medical and specialty
gases, and related equipment and 2) the manufacture of products for the
industrial gas and metals industries.

         Industrial, medical and specialty gases are distributed through the
Company's subsidiaries which operate in five divisions with locations in 38
states, Canada and Mexico. The industrial gas distribution market is broad and
includes most major industries.

applications in the medical, food packaging and certain high technology
electronic industries and calcium carbide and carbon products for the production
of acetylene gas and for the non-ferrous metal industry.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (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 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, 1996.

      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, 1996 and March 31, 1996;
the consolidated statements of earnings for the three and nine months ended
December 31, 1996 and 1995; and the consolidated statements of cash flows for
the nine months ended December 31, 1996 and 1995. The interim operating results
are not necessarily indicative of the results to be expected for an entire year.

(2)   ACQUISITIONS
      ------------

      From April 1, 1996 to December 31, 1996, the Company acquired twenty
businesses engaged in the distribution of industrial, medical and specialty
gases and welding supplies and two distributors of safety and industrial tools
and supplies, with aggregate annual sales of approximately $220 million. The
aggregate purchase price, including amounts related to non-competition and
confidentiality agreements, amounted to approximately $292 million and includes
cash and real estate acquired of $1.7 million and $4.8 million, respectively.
Included in the aggregate purchase price is the issuance of approximately 3.4
million shares of the Company's common stock, (which includes approximately 2.4
million shares which were issued out of treasury stock), issued in connection
with the September 1996 acquisition of Rutland Tool & Supply Co., Inc.
("Rutland"). 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.

      On October 29, 1996, the Company announced that it signed a letter of
intent to acquire Carbonic Industries Corporation ("Carbonic Industries"). In
the proposed transaction, Carbonic Industries will be merged into a newly-formed
subsidiary of the Company in exchange for a combination of the Company's common
stock and cash, and is expected to close during April 1997.

(7)   INDEBTEDNESS
      ------------

      On August 8, 1996, the Company commenced a medium-term note program
pursuant to a registration statement filed with the Securities and Exchange
Commission on July 15, 1996, which provides for the issuance of its securities
with an aggregate public offering price of up to $450 million. In September
1996, the Company issued the following long-term debt under the medium term note
program: (a) $100 million of unsecured notes due September 2006 bearing interest
at a fixed rate of 7.75%; and (b) $50 million of unsecured notes due September
2001 bearing interest at a fixed rate of 7.15%. The proceeds from the medium
term note issuances were used to repay bank debt. In connection with the
issuance of the notes, the Company entered into three reverse interest rate swap
agreements.

(8)   EARNINGS PER SHARE
      ------------------

      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.

(9)   COMMITMENTS AND CONTINGENCIES
      -----------------------------

     The Company is involved in 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.

     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 National Welders Supply Company, Inc.
("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.

(10)  FRAUDULENT BREACH OF CONTRACT
      -----------------------------

      On December 23, 1996, the Company announced that it was the victim of a
fraudulent breach of contract by a third party supplier related to purchases of
refrigerant R-12. Immediately upon discovering the fraud, the Company launched
an intense effort to recover funds paid to the supplier and/or recover product.

      Based on limited information currently available, the Company is unable to
quantify the probable amount of the loss or recovery which may be associated
with the fraud. The Company believes the maximum pre-tax loss, including
associated costs of the investigation and before considering any recoveries,
will not exceed $23 million, however, the minimum estimate is immaterial. At
December 31, 1996, prepaid expenses and other current assets

                                  (Unaudited)

include $23.7 million of costs associated with the fraud. The Company believes
there will be recoveries of assets related to the fraud, including cash in bank
accounts frozen under restraining orders, recovery of product paid for and not
delivered, net assets of the refrigerant supplier which breached the contract
and insurance proceeds under the Company's and the refrigerant supplier's
policies. The aggregate recovery amount, and the timing of recording various
portions thereof, is subject to change, even in the near term, as additional
assets are identified, additional claims are asserted or the market value of
restrained assets fluctuates. The Company will continue to vigorously pursue all
possible sources of recovery. The Company anticipates that it will record a
charge to earnings during the fourth quarter ending March 31, 1997, pending a
full investigation of the facts and information pertaining to the loss and
potential remedies.

      On February 12, 1997, the Company filed a lawsuit in the United States
District Court for the Southern District of Georgia against Discount Auto Parts,
Inc. ("Discount"), an employee of Discount, and certain other business and
individual defendants, alleging that Discount and the other defendants engaged
in racketeering activity involving the fraudulent sale of smuggled and
counterfeit R-12 refrigerant gas. The Company's complaint alleges that the
racketeering activity of the defendants caused damages to The Company in an
amount not less than $20 million. The complaint seeks treble damages under the
Federal RICO and Georgia RICO statutes, as well as monetary damages under other
counts alleging fraud, conspiracy and related wrongful conduct. The incident
described above on December 23, 1996 was part of the racketeering activity
alleged in the lawsuit filed. See "Airgas - Management's Discussion and Analysis
and Results of Operations - Recent Developments."

Notes to Financial Statements
================================================================================

Note 1.  Nature of Business and Significant Accounting Policies

Nature of Business:

Carbonic Industries Corporation ("The Company") is engaged in the manufacture
and sale of carbon dioxide products.  The Company operates primarily in the
Eastern United States, with additional operations in Texas and Arkansas.

Significant Accounting Policies:

Use of estimates:

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect certain reported amounts and disclosures.  Accordingly, actual results
could differ from those reported.

Cash and cash equivalents:

The Company considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents.

Inventories (in part):

Inventories are valued at the lower of cost or market on the first-in, first-out
basis.

Property and equipment:

Property and equipment are recorded at cost and depreciated using the straight-
line method over the following estimated useful lives:
<TABLE> 
 <S>                                                           <C> 
 Buildings and improvements                                    5 - 20 years
 Plant machinery and equipment                                 5 - 20 years
 Transportation equipment                                      3 - 10 years
 Receivers and related equipment                               5 - 20 years
 Dry ice shipping containers                                        5 years 
 Other equipment and furniture                                 5 - 10 years 
</TABLE> 
Depreciation expense amounted to $2,965,719, $2,950,913 and $2,948,031 for the
years ended December 31, 1996, 1995 and 1994, respectively.

Investment in joint venture (in part):

The investment in joint venture is accounted for by use of the equity method.

Unamortized intangible assets (in part):

All intangible assets are being amortized over their estimated useful lives
using the straight-line method.

Goodwill represents costs in excess of net assets of businesses acquired and is
amortized on a straight-line basis over the expected periods to be benefited,
which currently ranges from 15 to 40 years.  The Company assesses the
recoverability of these intangible assets by determining whether the
amortization of the goodwill balance over its remaining life can be recovered
through projected undiscounted future cash flows.

Income taxes (in part):

Income taxes are provided based on financial statement income before income
taxes.  Deferred income taxes reflect the impact of temporary differences
between the amounts of assets and liabilities recognized for financial statement
purposes and such amounts recognized for tax purposes.  These deferred income
taxes are measured by applying the provisions of currently enacted tax laws.

Notes to Financial Statements
================================================================================

Note 1.  Nature of Business and Significant Accounting Policies (continued)

Earnings per common share:

Earnings per common share is computed by dividing net income by the weighted
average number of common shares outstanding during the period.  Common share
equivalents have been excluded from this computation since they do not have a
dilutive effect of 3% or more.  The number of shares used in computing earnings
per common share was  856,059 in 1996, 855,359 in 1995 and 854,429 in 1994.

Financial Instruments:

The carrying amounts of receivables and accounts payable approximate fair value
because of the short-term maturity of these financial instruments.  The carrying
value of long-term debt approximates its fair value based on borrowing rates
available to the Company for loans of similar terms and maturities.

Reclassifications:

Certain amounts in the 1995 and 1994 financial statements have been reclassified
to conform to the 1996 financial statements presentation.

Note 4.  Investment in Joint Venture

On January 14, 1994, the Company entered into an agreement with Arcadian LCD
Corporation to form a 50/50 joint venture named AC Industries (the Joint
Venture).  The Joint Venture was formed to build, own and operate a 500 ton per
day carbon dioxide liquefaction plant in Augusta, Georgia.  The Joint Venture is
managed and operated by employees of the joint venturers under various expense
reimbursement agreements.  The carbon dioxide liquefaction plant was built by
Tomco\2\ Equipment Company (see Note 10).

The Joint Venture's primary customer is the Company.  During 1996, 1995 and
1994, the Company purchased carbon dioxide totaling $3,995,637, $4,010,691 and
$1,593,279, respectively, from the Joint Venture.  At December 31, 1996 and
1995, the Company owed the Joint Venture $1,033,358 and $653,959, respectively,
related to these purchases.

At December 31, 1996 and 1995, the Joint Venture owed the Company $80,165 and
$77,388, respectively, for reimbursement of expenses incurred on the Joint
Venture's behalf.

Distributions from the Joint Venture amounted to $700,000, $900,000 and $173,155
for the years ended December 31, 1996, 1995 and 1994, respectively.

During 1996, the Company made a $2,000,000 capital contribution to the Joint
Venture to partially fund an expansion project. At December 31, 1996, the
Company is committed to contributing at least another $3,100,000 to the Joint
Venture for this expansion project.  Subsequent to December 31, 1996, the
Company obtained a $2,000,000 short-term loan from SunTrust Bank to enable the
Company to fulfill this commitment.

Summary information on the Joint Venture as of and for the years ended December
31, 1996 and 1995 is as follows:

Note 9.  Retirement Plan

The Company has a 401(k) retirement plan which provides benefits for
substantially all employees of the Company who meet length of service
requirements.  Under the plan, qualified non-elective contributions are made by
the Company.  Additional annual contributions may be made by the Company at the
discretion of the Board of Directors.  Company contributions to the plan during
1996, 1995, and 1994 amounted to $223,736, $197,939, and $156,664, respectively.

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

Note 10.  Related Party Transactions

The Company purchases inventory and equipment from Tomco\2\ Equipment Company
(Tomco\2\), an entity related to the Company through substantially the same
ownership and officers.  These purchases amounted to $1,312,220 in 1996,
$1,757,225 in 1995 and $3,324,347 in 1994.

Accounts payable includes $173,114 and $330,379 at December 31, 1996 and 1995,
respectively, owed to Tomco\2\.

================================================================================
Note 11.  Concentrations

Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of temporary cash investments and trade
receivables.  The Company places its temporary cash investments with high
quality financial institutions. Concentrations of credit risk with respect to
trade receivables are limited due to the Company's large number of customers,
their dispersion across many industries and geographies and generally short
payment terms.

The Company's manufacturing process includes the purchase of unprocessed carbon
dioxide.  This unprocessed carbon dioxide is obtained from suppliers, usually as
a by-product of the supplier's manufacturing process (the source).  As of
December 31, 1996, the Company obtains this unprocessed carbon dioxide from five
suppliers, two of which supply 85% of the Company's needs.  Although the Company
has long-term purchase contracts with these suppliers, the contracts allow the
suppliers to cancel the contracts if they elect to close the source.

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

Note 12.  Commitments and Contingencies

Product Purchase Agreements:

The Company has various purchase agreements for certain amounts of carbon
dioxide.  Purchases under these agreements for 1996, 1995 and 1994 totaled
$8,763,000, $8,745,000 and $5,909,000, respectively.  Most of these agreements
have escalation clauses based on changes in the producer price index.  The
following schedule summarizes the future minimum payments required under these
agreements that have initial or remaining noncancellable terms of one year or
more as of December 31, 1996:

Note 12. Commitments and Contingencies (continued)

Included in the above minimum payments is $71,607,000 due to A.C. Industries and
the Company's joint venture partner (see Note 4).

Operating Lease Agreements:

The Company has various long-term operating lease agreements for the use of
office/warehouse facilities, railroad tank cars, trucks, tractors and other
equipment.  Some of the truck and tractor leases also call for additional rental
amounts based on miles driven.  Total rental expense in 1996, 1995 and 1994
amounted to $3,720,000, $3,233,000 and $2,502,000, respectively.

Litigation:

At December 31, 1996, a lawsuit which alleges violations of anti-trust laws is
pending against the Company.  This lawsuit alleges damages approximating
$9,000,000 against the Company and several of the Company's competitors.  The
Company and its competitors are vigorously contesting this lawsuit.  Management
believes that ultimate liabilities, if any, resulting from this lawsuit will not
materially affect the financial position or results of operations of the Company
and, therefore, no provision for loss has been made in the accompanying
financial statements.

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

Note 13. Capital Stock

The shares of "Class A" and "Class B" common stock are substantially identical
in rights, except that the owners of the "Class B" shares have the right to
elect a majority of the Board of Directors.

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

Note 14. Stock Options

On November 17, 1994, the Company's Board of Directors approved a stock option
plan.  The plan provides for the granting of incentive stock options and
nonqualified stock options to purchase 100,000 shares of the Company's "Class A"
common stock to directors, officers and other key employees at a price not less
than the fair market value on the date the option is granted.

Options become exercisable ratably over a five year period from the date of
grant, unless accelerated by a change of control in the Company's ownership.
Options expire ten years after the date of grant, unless accelerated by
termination of employment.

As permitted by Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" (SFAS No. 123), effective for 1996, the Company
continues to account for stock compensation costs in accordance with the
provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees".  Had compensation cost been determined based on the fair
value at the grant dates for awards under the Company's stock plan in accordance
with SFAS No. 123, net income would have been reduced by $133,968 ($.16 per
share) and $96,232 ($.11 per share) in 1996 and 1995, respectively.  As required
by SFAS No. 123, the fair value of each option granted is estimated on the date
of grant, using the Black-Scholes option pricing model with the following
assumptions for 1996 and 1995, respectively:  historical dividend yield of 4.0%
in both years; an expected life of 8 years in both years; expected volatility of
20% in both years and a risk-free rate of return of 6.7% and 5.4%.  The
weighted-average fair values of the options granted during 1996 and 1995 were
$3.20 and $3.18 per share, respectively.

     Stock Consideration shall be held and disbursed pursuant to the

     to this Article 2;

all subject to the rights and obligations of the CIC Shareholders' Agent
Committee as set forth in Article 8 of this Agreement (and without limiting the

      2.3 Class A Cash Election Procedure.
          ------------------------------- 

          (a) Generally.  Each CIC Class A Shareholder (other than holders of
              ---------                                                      
CIC Common Stock to be canceled as set forth in Section 2.2(e) and Dissenting
Shares) shall have the right to specify in a request made in accordance with the
provisions of this Section 2.3 (herein called a "Cash Election") the percentage
(not in excess of forty-five percent (45%), rounded down so that the election
applies to the next lower whole share and subject to adjustment as provided in
Section 2.9, the "Maximum Cash Percentage") of his shares of CIC Class A Common
Stock that he desires to have converted into the right to receive cash in the
Merger; provided, however, that the foregoing Maximum Cash Percentage limitation
does not apply to De Minimis Shares.

          (b) Distribution of Forms. CIC shall include a document in form and
              ---------------------                                          
substance agreed to by CIC and Airgas (the "Form of Cash Election/Transmittal
Letter") with the distribution to the CIC Shareholders of the Proxy
Statement/Prospectus (as defined in Section 3.30).  The Form of Cash
Election/Transmittal Letter will be designed among other things to permit the
CIC Class A Shareholders to exercise their right to make a Cash Election prior
to the Cash Election Deadline (as defined below).  Airgas shall use all
reasonable efforts to make available on a prompt basis a Form of Cash
Election/Transmittal Letter  to any CIC Class A Shareholder who requests such
form following the initial mailing of the Forms of Cash Election/Transmittal
Letters and prior to the Cash Election Deadline.

          (c) Delivery of Cash Elections.  Any Cash Election shall have been
              --------------------------                                    
made properly only if The Bank of New York (the "Exchange Agent") shall have
received, by 5:00 p.m. local time in New York, New York on the date of the Cash
Election Deadline, a Form of Cash Election/Transmittal Letter properly completed
and signed.  As used herein, "Cash Election Deadline" means the date mutually
agreed to in writing by Airgas and CIC (the "Cash Election Deadline Letter") as
the last day on which Forms of Cash Election/Transmittal Letters will be
accepted; provided, however, that such date shall be a business day no later
than five (5) business days prior to the Closing Date; provided, further, that
Airgas shall have the right to set a later date of, or to extend, the Cash
Election Deadline so long as such later date is no later than the Closing Date.

          (d) Limitations on Cash Election.  Any Cash Election that requests
              ----------------------------                                  
that more than the Maximum Cash Percentage of the CIC Class A Shareholder's CIC
Class A Common Stock be converted into cash shall be deemed a request that the
Maximum Cash Percentage be converted into cash.

          (e) Irrevocable.  Each Form of Cash Election/Transmittal Letter shall
              -----------                                                      
become irrevocable upon receipt by the Exchange Agent (unless the Exchange
Agent, in its sole and absolute discretion, permits its amendment or
withdrawal).

          (f) Rules.  Airgas and CIC (before the Merger) or the Shareholders'
              -----                                                          
Agent Committee (after the Merger) shall jointly have the right to make rules
and decisions (whether or not covered by such rules), not inconsistent with the
terms of this Agreement, governing the validity of the Forms of Cash
Election/Transmittal Letters.

      2.4 Dissenting Shares.  Notwithstanding anything in this Agreement to the
          -----------------                                                    
contrary, but only to the extent required by Chapter 607 of the FBCA, shares of
CIC Common Stock that are issued and outstanding immediately prior to the Merger
Effective Time and are held by CIC Shareholders who dissent from the Merger
("Dissenting Shares") shall not be converted into the right to receive Merger
Consideration, but shall instead become the right to receive such consideration
as may be determined to be due such holder of Dissenting Shares ("Dissenting
Shareholder") pursuant to Chapter 607 of the FBCA; provided, however, that if
any Dissenting Shareholder fails to establish and perfect such shareholder's
entitlement to dissenters' rights as provided by Chapter 607 of the FBCA, then
such Dissenting Shareholder shall forfeit dissenters' rights with respect to
such Dissenting Shares and such shares shall thereupon be deemed to have been
converted into the Merger Consideration to which such Dissenting Shares would
otherwise have been converted pursuant to Section 2.2, subject to all other
terms and conditions of this Agreement as if such CIC Shareholder had not
dissented or attempted to dissent (including the requirement that such CIC
Shareholder make the Shareholder Deliveries and that a portion of such Merger
Consideration may be deliverable to the Lockup/Escrow Agent) (as such term is
defined in the Lockup/Escrow Agreement).  CIC shall give Airgas prompt notice of
any written notices of any demand received by CIC for an appraisal of CIC Common
Stock, and CIC shall undertake in good faith to keep Airgas reasonably informed
of any other negotiations and proceedings with respect to demands for
dissenters' rights under Chapter 607 of the FBCA.  CIC will not, except with the
prior written consent of Airgas, settle or offer to settle any such demand.

      2.5 CIC Stock Options.
          ----------------- 

          (a) Generally.  At the Merger Effective Time, by virtue of the Merger
              ---------                                                        
and without any further action on the part of Airgas, CIC or the holder of any
unexpired and unexercised option to purchase shares of CIC Common Stock granted
under the CIC 1994 Stock Option Plan (a "CIC Stock Option"), each CIC Stock
Option shall be assumed by Airgas in such manner that Airgas is a corporation
"assuming a stock option in a transaction to which IRC (S) 424(a) applied"
within the meaning of IRC (S) 424 (or to the extent that IRC (S) 424 does not
apply to any such CIC Stock Options, would be such a corporation were IRC (S)
424 applicable to such CIC Stock Options).

          (b) Specifically.  Without being limited by the foregoing, at the
              ------------                                                 
Merger Effective Time, by virtue of the Merger and without any further action on
the part of Airgas, CIC or the holder of any CIC Stock Option, each CIC Stock
Option shall automatically become exercisable for that number of shares of
Airgas Common Stock equal to the number of shares of Airgas Common Stock that
would have been issued in the Merger with respect to such CIC Stock Option had
such option (assuming full vesting) been exercised immediately prior to the
Merger Effective Time (rounded up to the nearest whole number of shares of
Airgas Common Stock), assuming no Cash Election and no

                                       8
<PAGE>
 
contribution to the Fees & Expense Fund and (ii) at a price per share of Airgas
Common Stock equal to the per share option exercise price specified in the CIC
Stock Option multiplied by a fraction, the numerator of which is the Average
Airgas Price and the denominator of which is Forty Three Dollars ($43) (with the
result rounded to the nearest whole cent).  An example of the number of shares
of Airgas Common Stock issuable after the Merger pursuant to the CIC Stock

              ------------------                                            
made payable or Airgas Common Stock certificate is to be issued in the name of a
person other than the person in whose name the certificates for the shares of
CIC Common Stock surrendered for exchange therefor are registered, it shall be a
condition of the exchange that the person requesting such exchange shall

      2.9 Adjustments to Cash Merger Consideration.  Notwithstanding anything in
          ----------------------------------------                              
this Agreement to the contrary, if the Cash Elections (treating Dissenting
Shares as if a valid one hundred percent (100%) Cash Election were made with
respect to such shares) plus cash paid to CIC Class B Shareholders would
otherwise result in the Aggregate Cash Consideration exceeding the Aggregate
Stock Consideration, then each CIC Shareholders' Unadjusted Cash Percentage will
be decreased pro rata on a basis proportionate with all of the other CIC
Shareholders' Unadjusted Cash Percentages until the Aggregate Stock
Consideration is equal to or exceeds the Aggregate Cash Consideration; provided,
however, that no CIC Shareholder's Adjusted Cash Percentage shall be more than
two percentage points lower than his Unadjusted Cash Percentage; and provided
further that Cash Elections with respect to DeMinimis Shares are not subject to
any adjustment.   If a CIC Class A Shareholder's Unadjusted Cash Percentage is
adjusted pursuant to the foregoing, then the percentage of his Class A Stock
Consideration subject to the Lockup/Escrow Agreement pursuant to Section 2.2
(b)(iii)(2) (using the same assumptions set forth therein) shall be increased by
an amount equal to the amount determined by subtracting his Adjusted Cash
Percentage from his Unadjusted Cash Percentage.  As an illustration, if a Class
A CIC Shareholders' Cash Election is reduced from forty-five percent (45%) to
forty-four percent (44%), then his lockup/escrow percentage will increase from
fifty-five percent (55%) to fifty-six percent (56%).  The following definitions
are used in this Section 2.9:

          (a) "Adjusted Cash Percentage" means the percentage of a CIC
Shareholders' portion of the Aggregate Merger Consideration that is payable to
him promptly after the Closing in cash after any adjustments provided in this
Section 2.9.

          (b) "Aggregate Cash Consideration" means the amount of Aggregate
Merger Consideration payable promptly after the Closing in cash pursuant to this
Agreement.

                                       11
<PAGE>
 
          (c) "Aggregate Merger Consideration" means, collectively the Aggregate
Class A Merger Consideration and the Aggregate Class B Merger Consideration.

          (d) "Aggregate Stock Consideration" means the amount of Aggregate
Merger Consideration payable promptly after the Closing in Airgas Common Stock
pursuant to this Agreement.

          (e) "Unadjusted Cash Percentage" means, in the case of a CIC Class A
Shareholder, the otherwise valid cash percentage elected pursuant to his Cash
Election and, in the case of a CIC Class B Shareholder, forty-five percent
(45%).

warranty by CIC in this Agreement either (a) contains any untrue statement of a
material fact or (b) omits to state a fact necessary to make such representation
or warranty (giving full effect to any dollar, time or other limitation
specified in, and only with respect to the subject matter contained in, such
representation or warranty) not materially misleading.  The foregoing does not
impose any obligation to disclose the implication of disclosed facts.

      3.32 No Reliance on Forecasts.  In the negotiation and consideration
           ------------------------

and its business or financial results except:  (i) information and documents
that are publicly available, (ii) representations and warranties made by Airgas
in this Agreement, and (iii) disclosure of interim financial results made
pursuant to this Agreement.  In the course of negotiations, Airgas and CIC
exchanged information regarding hypothetical situations, based on various
assumptions, of the results of operations of the combined companies and possible
market prices for the Airgas Common Stock.  CIC makes no (and expressly
disclaims any) representation or warranty regarding any such hypothetical
situations provided by it, including those that may contain forecasts or
projections of its future operating results, and CIC disclaims reliance on any
such hypothetical situations provided by Airgas or third parties.

               REPRESENTATIONS AND WARRANTIES OF AIRGAS AND SUB
               ------------------------------------------------

Airgas and Sub hereby jointly and severally represent and warrant to CIC as
follows:

      4.1  Organization and Standing; Power and Authority.  Airgas and Sub
           ----------------------------------------------                 
are corporations duly organized, validly existing and in good standing under the
laws of the State of Delaware and have the full corporate power and corporate
authority to carry on their respective businesses, as they are now being
conducted, and to execute, deliver and perform this Agreement, and each document
to be executed and delivered by Airgas and/or Sub pursuant to this Agreement.
Airgas and Sub are each qualified as a foreign corporation in all jurisdictions
in which the failure so to qualify would have a material adverse effect on
Airgas or Sub, taken as a whole.  Except as set forth in Section 4.1 of the
Airgas Disclosure Schedule, Airgas has no subsidiaries or equity or other
interest in any entity. Sub is a newly-formed entity which has not conducted any
business and, except as set forth herein, has incurred no liabilities.

      4.2  Capitalization.  As of February 6, 1997, the authorized capital
           --------------                                                 
of Airgas consisted of 200,000,000 shares of common stock, $.01 par value per
share, of which 68,217,251 shares have been validly issued and are outstanding,
fully paid and nonassessable, and 20,000,000 shares of preferred stock and
30,000 shares of redeemable preferred stock, none of which is issued and
outstanding on the date hereof.  The authorized capital stock of Sub consists of
1,000 shares of common stock, par value $.01 per share, of which 100 shares have
been validly issued and are outstanding, fully paid and nonassessable on the
date hereof.  As of February 6, 1997, there were options outstanding to acquire
6,689,820 shares of Airgas Common Stock pursuant to the Airgas Option Plan.
Each such option has been duly authorized, and the shares of Airgas Common Stock
issuable upon exercise of the options, when issued and paid for in accordance
with the Airgas Option Plan, will be validly issued, fully paid and
nonassessable.  Except as set forth in Section 4.2 of the Airgas Disclosure
Schedule or as described above, Airgas has not reserved any shares of capital
stock for issuance and there are no outstanding options, restricted stock
awards, warrants, calls, commitments or rights of any character to purchase or
otherwise to acquire from Airgas shares of capital stock of any class, no
outstanding securities of Airgas that are convertible into shares of capital
stock of Airgas of any class, and no outstanding options, warrants or rights to
purchase from Airgas any of such convertible securities.

      4.3  Corporate Approval.
           ------------------ 

           (a) Each of Airgas and Sub has the necessary corporate power and
authority to execute, deliver and perform this Agreement and each other document
to be executed and delivered by it pursuant to this Agreement (collectively, the
"Airgas/Sub Delivered Documents").  The execution, delivery and performance of
this Agreement and of the Airgas/Sub Delivered Documents have been duly
authorized by the respective Boards of Directors of Airgas and Sub, as the case
may be (which authorizations shall not have been modified prior to the Closing
Date and shall be in full force and effect on the Closing Date), and no other
corporate proceeding on the part of Airgas or Sub

                                       24
<PAGE>
 
is necessary for the execution, delivery and performance of this Agreement by
Airgas and Sub. Subject to the filing of the Certificate of Merger and Articles
of Merger pursuant to Section 1.3, the performance by each of Airgas and Sub of
their respective obligations hereunder and under the Airgas/Sub Delivered
Documents does not violate any provision of the Certificate of Incorporation or
the By-Laws of either Airgas or Sub or the applicable rules and regulations of
the NYSE, the stock exchange on which the Airgas Common Stock is publicly
traded.

           (b) Airgas Common Stock - Valid Issuance. The shares of Airgas Common
               ------------------------------------
Stock to be issued to each holder of CIC Common Stock in connection with the
Merger will be duly authorized, validly issued, fully paid and nonassessable,
and, upon the effectiveness of the Registration Statement to be filed by Airgas
with the SEC pursuant to this Agreement, will be issued in compliance with the
Securities Act. From and after the Merger Effective Time, the assumption by
Airgas of the CIC Options pursuant to Section 2.5 will be duly authorized and
the shares that will be issuable upon exercise of such options, pursuant to the
terms set forth in Section 2.5 and the Airgas Option Plan, will be duly
authorized, validly issued, fully paid, and nonassessable. A sufficient number
of shares have been reserved under Airgas' Option Plan to provide for the
assumption of the CIC Options.

      4.4  Consents and Approvals; No Violations.  Except as set forth in
           -------------------------------------                         
Section 4.4 of the Airgas Disclosure Schedule, neither the execution, delivery
nor performance of this Agreement will (a) conflict with or result in any breach
of any provision of the Certificate of Incorporation or By-laws or similar
organizational documents of Airgas or Sub, (b) require any filing with, or
permit, authorization, consent or approval of, any Governmental Entity (i)
except where the failure to obtain such permits, authorizations, consents or
approvals or to make such filings would not have a material adverse effect on
Airgas or Sub and would not, or would not be reasonably likely to, materially
impair the ability of Airgas or Sub to consummate the Merger or the other
transactions contemplated hereby and (ii) except for all filings, permits,
authorizations, consents and approvals as may be required under, and other
applicable requirements of, the Securities Act, the Exchange Act, the state
securities or "blue sky" laws and the filing and recordation of the Certificate
of Merger and Articles of Merger as required by the DGCL and the FBCA, (c)
result in a violation or breach of, or constitute (with or without due notice or
lapse of time or both) a default (or give rise to any right of termination,
amendment, cancellation or acceleration) under, any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, guarantee, other evidence of
indebtedness, lease, license, contract, agreement or other instrument or
obligation to which Airgas or Sub is a party or by which any of their properties
or assets may be bound or (d) violate any applicable law applicable to Airgas or
Sub or any of their properties or assets, except in the case of clauses (c) and
(d) for violations, breaches or defaults which would not have a material adverse
effect on Airgas or Sub.

      4.5  Binding Obligation.  The Airgas/Sub Delivered Documents, when
           ------------------                                           
executed and delivered by Airgas and/or Sub (as applicable) have been or will
be, as the case may be, duly and validly executed and delivered by Airgas and
Sub.  This Agreement and each Airgas/Sub Delivered Document constitutes or will
constitute a legal, valid and binding obligation of Airgas and Sub (as
applicable), enforceable in accordance with its respective terms, except to the
extent that its

                                       25
<PAGE>
 
enforceability may be subject to limitations imposed by general principles of
equity (regardless of whether such enforceability is considered in a proceeding
at law or in equity) and to the effect of applicable bankruptcy, reorganization,
insolvency, moratorium and similar laws of general application relating to or
affecting creditors' rights, including, the effect of statutory or other laws
regarding fraudulent conveyances and preferential transfers, provided, however,
that the Certificate of Merger and the Articles of Merger will not be effective
until filed with the Delaware and Florida Secretaries of State, respectively.

      4.6  Consents.  Neither Airgas nor Sub is subject to any applicable
           --------                                                      
law or other restriction that would prevent the consummation of this Agreement
that would require the consent of any third party to the consummation of this
Agreement or any of the transactions contemplated hereby or, to the knowledge of
Airgas or Sub, that would result in any penalty, forfeiture or termination which
would be materially adverse to Airgas or Sub as a result of such consummation,
other than the consents described in Section 4.6 of the Airgas Disclosure
Schedule.

      4.7  Obligations; Absence of Violation.  Sub has no obligations other
           ---------------------------------                               
than those contemplated by this Agreement.  Neither the execution, delivery nor
performance of this Agreement constitutes a violation or default under, or
conflicts with, or will result in the creation of any encumbrances on any of the
assets owned by Airgas or Sub under, any term or provision of the respective
Certificate of Incorporation or Bylaws of Airgas or Sub, or any agreement,
including, any contract, license, commitment, lease, instrument, arrangement or
understanding to which Airgas or Sub is a party or to which Airgas, Sub or any
of their respective property is subject, or by which Airgas, Sub or any of their
respective property is bound, where such encumbrance would be materially adverse
to Airgas or Sub.

      4.8  Disclosure.  To Airgas' knowledge, none of the information
           ----------

Agreement, (b) the Registration Statement and (c) the Proxy Statement/Prospectus
at the respective times that (i) the Registration Statement becomes effective,
(ii) the Proxy Statement/Prospectus is mailed and (iii) any meeting of
shareholders (and any adjournment thereof) is held to consider, or written
consents are effective with respect to approval of, the Merger, as such Proxy
Statement/Prospectus or Registration Statement is then amended or supplemented,
shall contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The Registration
Statement and Proxy Statement/Prospectus will comply in all material respects as
to form with applicable provisions of the Securities Act and the Exchange Act.

      4.9  SEC Reports.  Airgas (a) has furnished CIC with copies of its
           -----------

effective or was filed with the SEC, as the case

                                       26
<PAGE>
 
may be, complied in all material respects with the requirements of the
Securities Act and the Exchange Act, as applicable, and the rules and
regulations of the SEC thereunder and each SEC Filing did not on the date of
effectiveness or filing, as the case may be, contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
therein, in the light of circumstances under which they were made, not

representation or warranty regarding any such hypothetical situations provided

operating results, and Airgas and Sub each disclaim reliance on any such
hypothetical situations provided by CIC or third parties.

the Confidential Information to prevent it from falling into the public domain
or the possession of unauthorized persons and to advise the other party in
writing of any misappropriation or misuse by any person of such Confidential
Information of which it may become aware.

           (e) Return.  Any materials or documents which are furnished by the
               ------                                                        
disclosing party, and all copies thereof, will be returned by the receiving
party promptly following the earlier of (i) the termination of this Agreement or
(ii) receipt of a written request for the return of such information.

           (f) No License or Warranty. No license is granted to any party hereto
               ----------------------
under any patents, copyrights or other proprietary rights by the disclosure of
any information hereunder, nor is any warranty made as to such information.

           (g) Remedies.  Each party understands and agrees that, because of the
               --------                                                         
unique nature of the Confidential Information, the disclosing party will suffer
immediate, irreparable harm in the event the receiving party fails to comply
with any of its obligations under this Section 5.4, that monetary damages will
be inadequate to compensate the disclosing party for such breach, and that the
disclosing party shall have the right to enforce the provisions of this Section
5.4 by injunctive or other equitable remedies.  Each party waives any
requirement that a party undertaking to enforce any provision of this Section
5.4 must post a bond or take any similar action as a condition to making such
claim.

shall recommend to the CIC Shareholders the approval of this Agreement and the
transactions contemplated hereby; and shall include such recommendation in the
Proxy Statement/Prospectus; provided, however, that CIC may withdraw, modify or
change such recommendation to the extent that the Board of Directors of CIC
determines, after having received the advise of outside legal counsel to CIC,

likely to result in a breach of the Board of Directors' fiduciary duties under
applicable law. To permit shareholder consideration and approval of the Merger,
CIC shall cause to be duly called a special meeting of the CIC Shareholders (the
"CIC Special Meeting") to be held as promptly as practicable after the

entity or group (other than Airgas or any affiliate or an associate of Airgas)
concerning any merger, sale of any material portion of CIC's assets not in the
ordinary course of business, sale of shares of capital stock or similar
transactions involving the acquisition of CIC.  CIC shall promptly notify Airgas
in writing of any such inquiry, contact or proposal (including successive
inquiries, contacts or proposals) and shall in such notice indicate the identity
of the person and the terms and conditions of any inquiry, contact or proposal,
including price.

      6.4  News Releases.  Except as may be otherwise required for
           -------------

or approve any news release or other public announcement concerning the Merger
without the prior approval of the other (which shall not be unreasonably
withheld or delayed), except (a) as may be required by applicable law, including
the rules, regulations or practices of the SEC or the NYSE or (b) in connection
with notifying its shareholders of this Agreement or the transactions
contemplated hereby.  If a public statement is required to be made by applicable
law, the party making such statement shall be entitled to include explanatory
information or commentary in addition to required information .  The parties
shall consult with each other in advance to the extent reasonably practicable as
to the contents and timing of the public statement.  Without limiting the
foregoing, Airgas shall be given prior notice of any general announcement or
general notice to CIC's employees concerning the transactions contemplated by
this Agreement.

      6.5  SEC Filing.  Airgas and CIC shall (together or pursuant to an
           ----------                                                   
allocation of responsibility to be agreed upon between them) (i) prepare and
file with the SEC as soon as practicable the Proxy Statement/Prospectus and the
Registration Statement, (ii) respond to comments of and furnish all information
requested or required by the SEC, (iii) use their diligent efforts to have such
Registration Statement (with the Proxy Statement/Prospectus included therein)
promptly declared effective by the SEC, (iv) take all such action as may be

      6.6  Certain Employee Matters.
           ------------------------ 

           (a) Continued Employment.  Except as otherwise provided in Subsection
               --------------------                                             
(c) below, each employee who continues as an employee of CIC after the Closing
will be covered under Airgas' benefits plans for comparable employees.  Without
limiting the foregoing and subject to Subsection (c) below, all time such
employees have been employed by CIC shall be counted for eligibility
participation, vesting and (except for defined benefit pension plans) benefit
accrual purposes under all of Airgas' employee benefit plans.

           (b) Vacation. Airgas shall cause Sub to continue to recognize all
               --------                                                     
accrued but unused vacation for employees of CIC as disclosed in Exhibit 6.6(b).
Airgas shall cause Sub to give each employee credit for prior years of service
with CIC for purposes of calculating vacation that may be received pursuant to
Sub's vacation policy that may be in effect from time to time after Closing and
will waive any eligibility requirements of such policy with respect to such
employees.

           (c) Group Insurance Plans.  Airgas will cause Sub to continue CIC's
               ---------------------                                          
group insurance plans in their current form for CIC's employees on the Closing
Date and continue such plans in such form until it has arranged for such
employees to participate in another plan maintained by Airgas (and Airgas shall
obtain the waiver of the waiting period for participation in such plan, first
day at work requirement and any restrictions and limitations on pre-existing
medical conditions under such plan for employees participating in and covered
immediately prior to the Merger Effective Time by CIC's group insurance plans).

           (d) 401(k) Plan.  Airgas shall cause Sub to make contributions and
               -----------                                                   
other decisions for the current plan year under CIC's 401(k) plan disclosed in
Section 3.16 of the CIC Disclosure Schedule in accordance with the 1996
practices (consistent with the plan documents and applicable law). Airgas shall
cause CIC to make distributions from the 401(k) plan to terminated employees in
accordance with the plan documents and applicable law but otherwise as soon as
is practicable.

      6.7  Certain Assets. Commencing on the Closing Date and continuing
           --------------                                               
until the first anniversary of the Closing Date, J. Vernon Hinely (and/or
Florida Carbonic, Inc. and/or Dry Ice Sales, Inc.) shall have an option to
acquire the assets and business of CIC's dry ice operations (including customer
lists and all related assets and the right to hire local dry ice employees, but
excluding real property) in Miami and/or Jacksonville, Florida in accordance
with the terms of Exhibit 6.7.

      6.8  NYSE Listing.  Prior to the Closing Date, Airgas shall use its
           ------------                                                  
best efforts to cause to be authorized for listing on the NYSE (subject only to
official notice of issuance) the shares of Airgas Common Stock to be issued as
Merger Consideration pursuant to this Agreement and the shares of Airgas Common
Stock issuable pursuant to the exercise after the Merger of the CIC Stock
Options.

      6.9  Rule 145.  Airgas covenants for a period of two years (or such
           --------                                                      
shorter period as shall be required to permit sales of the Airgas Common Stock)
following the Merger Effective Time that

                                       33
<PAGE>
 
it will file any reports required to be filed by it under the Securities Act and
the Exchange Act, and the rules and regulations adopted by the SEC thereunder
(or, if Airgas is not required to file such reports, it will, upon the request
of any holder of shares of Airgas Common Stock issued in connection with the
Merger, make publicly available other information so long as it is necessary to
permit sales under Rule 145 under the Securities Act but only if Airgas
otherwise makes such information publicly available) and that it will take such
further action as any holder of Airgas Common Stock issued in connection with
the Merger may reasonably request, all to the extent required from time to time
to enable such shareholders to sell shares of Airgas Common Stock within the
limitation of the exemptions provided by (a) Rule 145 under the Securities Act,
as such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC.

      6.10  Insurance.  Airgas acknowledges that certain insurance policies
            ---------                                                      
that were obtained on behalf of both CIC and Tomco\\2\\ Equipment Company
("Tomco\\2\\") contain provisions for retroactive premium and dividend
adjustments.  Such policies may continue to have retroactive adjustments that
will need to be allocated between CIC and Tomco\\2\\ before and after the
Closing.  The parties agree for each other's benefit and for the benefit of
Tomco\\2\\ that such allocations will be made fairly, consistent with CIC and
Tomco\\2\\'s prior practice, and that any credits due to Tomco\\2\\ will be paid
promptly by CIC.

      6.11  Release of Tomco Collateral.  Airgas agrees for the benefit of
            ---------------------------                                   
Tomco\\2\\ that it (a) shall in good faith undertake to obtain the release by
Jefferson-Pilot Life Insurance Company of all liens and security interests in
Tomco\\2\\'s assets that secure CIC's obligations to Jefferson-Pilot  (which
obligations are listed in section 3.14 of the CIC Disclosure Schedule), (b)
shall in good faith undertake to file or cause the filing of all UCC termination
statements, terminations of  mortgages and other similar documents necessary to
evidence such release in the public records and (c) if such releases are not
obtained and evidence of terminations not so filed, shall indemnify, defend and
hold Tomco\\2\\ harmless against any liability, loss, cost or expense, including
attorneys' fees and expense arising as a result of or in connection with such
liens and security interests.

      6.12  Hinely Office Furniture and Fixtures.  Airgas does hereby agree
            ------------------------------------                           
to notify J. Vernon Hinely at least 30 days prior to disposition of any of the
furniture and fixtures currently in his office in Orlando, Florida (the "Office
Furniture") and, if he gives counter notice within such 30-day period electing
to purchase some or all of the Office Furniture, to sell him each such elected
item of the Office Furniture at its then-depreciated book value.

                                INDEMNIFICATION
                                ---------------

      7.1  Indemnification.  If the Closing occurs, then from and after the
           ---------------                                                 
Merger Effective Time, to the extent and as provided in this Article 7, Airgas,
Sub and their respective executive officers and directors (all such persons who
are entitled to indemnification are hereinafter referred to individually as an
"Indemnified Person" and collectively as "Indemnified Persons") shall be
indemnified and held harmless by the CIC Shareholders (the "Indemnifying
Persons") from and against any and all

                                       34
<PAGE>
 
damages, claims losses, liabilities and expenses, including, without limitation,
reasonable legal, accounting and other expenses (the "Damages"):

           (a)  arising out of any breach of a representation, warranty or
covenant of CIC contained in this Agreement or any of the CIC Delivered
Documents;

           (b)  arising from any failure to make filings if such were required
pursuant to the matter disclosed in Item I of Section 3.27 of the CIC Disclosure
Schedule;

           (c)  relating to any additional investigation and/or remediation as a
result of the former presence of two USTs at 1300 Bellwood Road;

           (d)  relating to any additional investigation and/or remediation as a
result of the former presence of two USTs at 2502 NW 38th Street, Miami,
Florida; and

           (e)  for any decrease in any tax benefits ("Tax Benefits") otherwise
available to Sub for any taxable period ending after the Closing Date by reason
of an adjustment with respect to any return for Taxes filed by CIC on or prior
to the Closing Date in an amount equal to the aggregate net difference between
the actual tax liability of Sub (or its assignee) and the tax liability that
would have been incurred by Sub (or its assignee) if any such Tax Benefits had
not been reduced in the aggregate).

      7.2  Procedures for Claims.  The Indemnified Persons' rights to be
           ---------------------                                        
indemnified under this Article 7 shall be subject to the following procedures:

           (a) Notice of Claim.  If an Indemnified Person shall in good faith
               ---------------                                               
have any claim for Damages, Airgas shall promptly give notice thereof to the
Shareholders' Agent Committee and the Lockup/Escrow Agent, including a brief
description of the facts upon which such claim is based and the quantifiable
nature of the Damages (a "Notice of Claim").

           (b) Notice of Objection. If the Shareholders' Agent Committee desires
               -------------------
in good faith to dispute a claim for indemnification, or a portion thereof, it
shall notify Airgas and the Lockup/ Escrow Agent in writing of its objections
thereto (a "Notice of Objection") within thirty (30) days following its receipt
of a Notice of Claim. If the Shareholders' Agent Committee does not make a
Notice of Objection within such thirty (30) days period, then the subject Notice
of Claim shall be satisfied as provided in Section 7.5 below.

           (c) Arbitration.  If, within sixty (60) days after Airgas' receipt of
               -----------                                                      
a Notice of Objection, Airgas and the Shareholders' Agent Committee shall not
have reached agreement as to the claim in question, then the claim for
indemnification shall be submitted to and settled by arbitration as provided
below (it being expressly understood and agreed that if such Notice of Objection
is duly given, it is the intention of the parties and the Shareholders' Agent
Committee that

                                       35
<PAGE>
 
any such claim shall be resolved by arbitration as provided in this section).
Arbitration shall be by a single arbitrator experienced in the matters at issue
and selected by Airgas and the Shareholders' Agent Committee in accordance with
the Commercial Arbitration Rules of the American Arbitration Association as then
in effect (the "Rules").  The arbitration shall be held in such place in the
Atlanta, Georgia metropolitan area as may be specified by the arbitrator (or any
place agreed to by Airgas, the Shareholders' Agent Committee and the
arbitrator), and shall be conducted in accordance with the Rules and (regardless
of any other choice of law provision in this Agreement) the United States
Arbitration Act (9 U.S.C. (S)(S) 1-16) to the extent not inconsistent with this
Agreement (and the "Expedited Procedures" set forth in the Rules shall be
applicable to any disputes involving less than $50,000).  The decision of the
arbitrator will be final and binding upon the parties, and judgment upon the
arbitrator's decision may be entered in any court of competent jurisdiction.

           (d) Release of Claim.  Notwithstanding any other provision of this
               ----------------                                              
Section 7.2, Airgas may at any time assume full control over and responsibility
for any claim by giving notice to the Shareholders' Agent Committee and the
Lockup/Escrow Agent withdrawing the Notice of Claim and waiving its
indemnification rights with respect to the subject claim.

      7.3  Third Party Claims.
           ------------------ 

           (a) Notice of Third Party Claim.  Within fifteen (15) days after
               ---------------------------                                 
receipt of notice of commencement of any action by any third party evidenced by
service of process or other legal pleading, or with reasonable promptness after
the assertion in writing of any claim by a third party, Airgas shall give the
Shareholders' Agent Committee written notice thereof together with a copy of
such claim, process or other legal pleading (a "Notice of Third Party Claim"),
and the Shareholders' Agent Committee shall have the obligation to undertake the
defense, settlement, compromise or other disposition thereof through a legal
representative of the Shareholders' Agent Committee's own choosing.  Airgas and
its counsel shall have the right to be present at the negotiation, defense and
settlement of such action or claim, and any settlement or compromise of any such
action or claim shall be subject to the approval of Airgas which approval shall
not be unreasonably withheld or delayed.

           (b) Defense by Airgas.  In the event that the Shareholders' Agent
               -----------------                                            
Committee by the thirtieth (30th) day after receipt of a Notice of Third Party
Claim (or, if earlier, by the tenth day preceding the day on which an answer or
other pleading must be served in order to prevent judgment by default in favor
of the person asserting such claim) does not elect to defend against such claim,
Airgas will have the right to undertake the defense, compromise or settlement of
such claim on behalf of and for the account and risk of the Indemnifying Person
subject to the right of the Shareholders' Agent Committee to approve (which
approval shall not be unreasonably withheld or delayed) any compromise or
settlement and to assume, on behalf of the Indemnifying Persons, the defense of
such claims at any time prior to settlement, compromise or final determination
thereof; and provided further, that if the Shareholders' Agent Committee submits
to Airgas a bona fide settlement offer from the third party claimant of any
Third Party Claim (which settlement offer shall include as an unconditional term
of it the release by the claimant or the plaintiff to Airgas from all liability
in respect of such claim) and Airgas refuses to consent to such settlement, then
thereafter the Shareholders'

                                       36
<PAGE>
 
Agent Committee's liability to Airgas for indemnification with respect to such
third party claim shall not exceed the settlement amount included in such bona
fide settlement offer, and Airgas shall either assume the defense of such third
party claim or pay the Shareholders' Agent Committee's reasonable attorney's
fees and other out-of-pocket costs incurred thereafter in continuing the defense
of such third party claim.  Notwithstanding the forgoing, Airgas shall have the
right to retain control of the defense of any third party action or claim
described in Section 7.2(a) which (i) involves potential Damages in excess of
the amount determined by subtracting (A) the sum of all Final Determinations (as
defined in the Lockup/Escrow Agreement) plus the potential Damages in such third
party action from (B) $5,000,000 or (ii) could reasonably be expected to
materially adversely affect Airgas or its operations.  In such event, the
Shareholders' Agent Committee and its counsel shall have the right to be present
at the negotiation, defense and settlement of such action or claim, and any
settlement or compromise of any such action or claim shall be subject to the
approval of the Shareholders' Agent Committee, which approval shall not be
unreasonably withheld or delayed.

      7.4  Limitations on Indemnification Rights.
           ------------------------------------- 

           (a) Outside Date for Claims. No claim for indemnification pursuant to
               -----------------------
this Article 7 shall be made unless a Notice of Claim with respect to such is
given in compliance with Section 7.2(a) on or prior to the Termination Date (as
defined herein).

           (b) Offset for Insurance Proceeds.  Any claim for Damages hereunder
               -----------------------------                                  
shall be offset or reduced by the amount of any third party insurance proceeds
as to which there is no reimbursement or comparable obligation received by the
Indemnified Person for such Damages.

           (c) Deductible.  The Indemnified Persons shall be entitled to
               ----------                                               
indemnification pursuant to this Article 7 only to the extent that the aggregate
amount of indemnified Damages exceeds $500,000 (the "Deductible"); provided,
however, that the foregoing limitation shall not apply to any Damages arising as
a result of disclosure or failure to disclose that a party demonstrates was
solely for the purpose of misleading the other party or a breach of the
representation and warranty in Section 3.26.

           (d) Cap.  The Indemnified Persons shall only be entitled to
               ---                                                    
indemnification pursuant to this Article 7 for up to $5,000,000 in Damages after
giving effect to the Deductible (except that such cap shall not apply to any
Damages arising as a result of a breach of the representation and warranty in
Section 3.26).

           (e) Lockup/Escrow as Sole Source. The Lockup/Escrow shall be the sole
               ----------------------------
and exclusive source for the satisfaction of such indemnification rights. No CIC
Shareholder shall have any liability or obligation with respect to such
indemnification rights except through the application of his Lockup/Escrow
Shares as provided herein and in the Lockup/Escrow Agreement.

           (f) Mitigation of Damages.  The Indemnified Person shall act in good
               ---------------------                                           
faith and in a commercially reasonable manner to mitigate any Damages it may
suffer.

<PAGE>
 
           (g) Third Party Claims.  The Indemnified Person may not make a claim
               ------------------                                              
for Damages arising out of a third party claim unless the third party has made
its claim in writing.

           (h) Knowledge of Breaches.  No Indemnified Person shall be
               ---------------------                                 
indemnified, or have any other recovery, for Damages arising from any inaccuracy
in, or a breach of, any representation, warranty, covenant or agreement by CIC
if Airgas had actual knowledge at or before the Closing that such
representation, warranty, covenant or agreement was inaccurate or breached.  For
purposes of this Section 7.4(h), Airgas shall be deemed to have actual knowledge
of any such facts actually known to any of Andrew R. Cichocki, John T. Winn, III
or Thomas Mason after (i) a meeting (telephonic or otherwise) of them (and
Airgas' attorneys representing it in this transaction) devoted to a review of
this Agreement and their due diligence reports and (ii) a discussion with an
individual who could reasonably be expected to have knowledge of or familiarity
with such facts.

      7.5  Satisfaction of Indemnification Obligations.  Subject to the
           -------------------------------------------                 
procedures and limitations set forth in this Article 7 and to the provisions of
the Lockup/Escrow Agreement, claims for Damages shall be satisfied by the
Lockup/Escrow Agent as provided in the Lockup/Escrow Agreement.

      7.6  Other Rights and Remedies Not Affected.  If the Merger is consummated
           --------------------------------------                               
as contemplated herein, this Article 7 and the Lockup/Escrow Agreement shall set
forth the sole and exclusive remedy and recourse (and corresponding liability
for the CIC Shareholders) of any Indemnified Person for Damages or any other
claim, cause of action or right of any nature against CIC or the CIC
Shareholders in connection with this Agreement, and the consummation of the
Merger and the transactions contemplated hereby and thereby; provided, however,
in the event of fraud by CIC or any CIC Shareholder in connection with this
Agreement and the consummation of the Merger and the transactions contemplated
hereby and thereby, then the indemnification rights of the Indemnified Person
under this Article 7 are independent of and in addition to such rights and
remedies as the Indemnified Person may have at law or in equity or otherwise,
including without limitation the right to seek specific performance, rescission
or restitution, none of which rights or remedies shall be affected or diminished
hereby.

      7.7  Survival of Representations, Warranties and Covenants.  All
           -----------------------------------------------------      
representations, warranties and agreements in this Agreement or in any document
delivered pursuant to this Agreement shall survive the Closing for a period of
one (1) year following the Closing Date (the "Termination Date") and,
thereafter, to the extent a good faith claim is made prior to the Termination
Date (but only as to those representations, warranties and agreements (or
portions thereof) claimed to have been breached), until such claim is finally
determined or settled.

      7.8  Consent as to Representation.  AIRGAS AND SUB EACH ACKNOWLEDGE THAT

certificates representing the Lockup/Escrow Shares of each CIC Shareholder for a
number of Airgas Shares having a value at least equal to each such CIC
Shareholder's Share of the Final Determination.  If any such certificate

then Airgas shall issue (or shall cause to be issued) a new share certificate
representing the balance of the Lockup/Escrow Shares to such CIC Shareholder
(without cost to such CIC Shareholder or the Lock-up/Escrow Agent)  and shall
return it to the Lock-up/Escrow Agent to be held in accordance with this
Agreement.

     3.3  Obligation to Execute and Deliver.  Airgas and the CIC Shareholders'

received prior to __________ __, 1998/4/, then the number of Lockup Escrow
Shares that are distributed shall be reduced by an amount of the Lockup/Escrow

rights were exercised), less (b) the amount of any prior distribution of
Lockup/Escrow Shares (valued at the Airgas Stock Value) to Airgas in accordance
with Article 3.  "Termination Tax Opinion" means either (i) a legal opinion from
a law firm satisfactory to Airgas and the CIC Shareholders' Agent Committee that
the distribution contemplated by this Section 4.1 and any subsequent disposition
of the Lockup/Escrow Shares so distributed would not cause the Merger to fail to
qualify as a "reorganization" within the meaning of IRC (S) 368(a) or (ii) a
legal opinion in the form of Exhibit B from Sutherland, Asbill & Brennan, L.L.P.

(or any successor firm).

     4.2  At Second Anniversary. On __________ __, 1999/5/, the Lockup/Escrow
          ---------------------
Agent shall distribute the Lockup/Escrow Shares then held by it to the CIC
Shareholders' Agent Committee, less an amount of Lockup/Escrow Shares equal in
value (valued at the Airgas Stock Value) to the amount of any Indemnification
Claim with respect to which there has been no Final Determination.

     4.3  Certain Retained Amounts.  To the extent Lockup/Escrow Shares, which
          ------------------------                                            
were due to be distributed to the CIC Shareholders pursuant to Section 4.2, were
not so distributed by reason of Indemnification Claims as to which there has
been no Final Determination ("Retained Lockup/Escrow Shares"), such Retained
Lockup/Escrow Shares shall continue to be held by the Lockup/Escrow Agent
pursuant to this Agreement solely with respect to the specific matter covered by
each such Indemnification Claim (and not with respect to any other matter or any
other Indemnification Claims) until the Lockup/Escrow Agent has received a Final
Determination relating to such Retained Lockup/Escrow Shares.  Upon receipt of
such Final Determination, the Lockup/Escrow Agent shall, as the case may be:

          (a)   To Airgas:  distribute to Airgas the amount, if any, of such
                ---------
Retained Lockup/Escrow Shares to which it is entitled pursuant to the Final
Determination, in accordance with Sections 3.1 and 3.2; and

          (b)   To the CIC Shareholders' Agent Committee: distribute such
                ----------------------------------------
balance to the CIC Shareholders' Agent Committee.

     4.4  Distribution to the CIC Shareholders' Agent Committee.  The
          -----------------------------------------------------      
Shareholders' Agent Committee shall, subject to its rights in Merger Agreement
(S) 8.2(d) (and in that connection, Airgas agrees to reissue shares generally in
accordance with the last two sentences of Section 3.2 in order to effect the CIC
Shareholders' Agent Committee's rights in accordance with Merger Agreement (S)
8.2(d)), distribute to the CIC Shareholders the Lockup/Escrow Shares distributed
to it pursuant to the terms of this Article 4; provided, however, that if the
CIC Shareholders' Agent Committee directs, the Lockup/Escrow Agent shall
distribute such balance directly to the CIC Shareholders on whose behalf such
Retained Lockup/Escrow Shares were held.

     ARTICLE 5: DISPOSITION OF SHARES SUBJECT TO, AND RELEASE OF SHARES FROM,
     ========================================================================
     THIS AGREEMENT.
     ============== 

     5.1  General.  If any CIC Shareholder desires to sell, transfer, give
          -------                                                         
(whether in trust or otherwise), pledge, encumber, hypothecate, or dispose in
any fashion of all or any of his, hers or its Airgas Shares held by the
Lockup/Escrow Agent subject to this Agreement, such CIC Shareholder, the CIC
Shareholders' Agent Committee, Airgas and the Lockup/Escrow Agent shall follow
the procedures set forth in this Article.

     5.2  Written Request.  The CIC Shareholder desiring to engage in any
          ---------------                                                
proposed sale, transfer, gift, pledge, encumbrance, hypothecation, or other
disposition of all or any of his Lockup/Escrow Shares subject to this Agreement
(a "Proposed Disposition") must submit in writing (in a form reasonably
acceptable to the CIC Shareholders' Agent Committee) to the CIC Shareholders'
Agent Committee and to Airgas a request for authorization to engage in the
Proposed Disposition (the "Request").  The Request shall contain all the details
of the Proposed Disposition as the CIC Shareholder in good faith determines the
CIC Shareholders' Agent Committee and Airgas might need to make the
determination required under Section 5.3, and the CIC Shareholders' Agent
Committee and Airgas may require the CIC Shareholder to supplement the Request
with additional information that the Lockup/Escrow Agent and Airgas in good
faith determine is needed to make the determination required under Section 5.3.

     5.3  Determination of CIC Shareholders' Agent Committee.  The CIC
          --------------------------------------------------          
Shareholders' Agent Committee and Airgas shall review the Request (and any
supplemental information) as promptly as reasonably practicable and shall
determine whether or not, in the sole and complete discretion of the CIC
Shareholders' Agent Committee and Airgas, there is a meaningful risk that the
Proposed Disposition, if consummated, would cause the Merger to fail to qualify
as a "reorganization" within the meaning of IRC (S) 368(a).  In discharging this
duty, the CIC Shareholders' Agent Committee and Airgas, in their sole and
complete discretion, may do any, all, or none of the following:  (a) consult
with expert counsel, with the expense thereof to be paid by the CIC Shareholder
making the request; (b) require the CIC Shareholder to make available expert
counsel, at the CIC Shareholder's expense, with whom the CIC Shareholders' Agent
Committee and Airgas may consult; (c) require the CIC Shareholder's expert
counsel to deliver a legal opinion, at the CIC Shareholder's expense and
satisfactory to the CIC Shareholders' Agent Committee and Airgas, that the
Proposed Disposition, if consummated, would not cause the Merger to fail to
qualify as a "reorganization" within the meaning of IRC (S) 368(a); or (d)
conditionally approve the Proposed Disposition, including, but not limited to,
the imposition of any of the conditions referenced in Section 5.5.  Such CIC
Shareholder shall also pay the fees and expenses of any counsel retained by the
CIC Shareholders' Agent Committee to assist and advise it in its review of the
Request.

     5.4  Effect of CIC Shareholders' Agent Committee's Determination.  If the
          -----------------------------------------------------------         
CIC Shareholders' Agent Committee and Airgas determine that there is no
meaningful risk that the Proposed Disposition, if consummated, would cause the
Merger to fail to qualify as a "reorganization" within the meaning of IRC (S)
368(a), then the Proposed Disposition shall be approved, subject to whatever
conditions (including any of those referenced in Section 5.5) the

                                       6
<PAGE>
 
CIC Shareholders' Agent Committee and Airgas may impose and give notice of such
determination to the CIC Shareholder, then such CIC Shareholder may consummate
the Proposed Disposition (but no other transaction with respect to the
Lockup/Escrow Shares).  If the CIC Shareholders' Agent Committee and Airgas fail
to determine that there is no such substantial risk, the Proposed Disposition
shall not be approved and shall not be consummated.  ANY ATTEMPTED DISPOSITION
OF AIRGAS SHARES SUBJECT TO THIS AGREEMENT OTHER THAN PURSUANT TO A PROPOSED
DISPOSITION THAT IS APPROVED BY THE CIC SHAREHOLDERS' AGENT COMMITTEE AND AIRGAS
PURSUANT TO THIS ARTICLE 5 SHALL BE NULL AND VOID AND OF NO FORCE OR EFFECT
WHATSOEVER.

     5.5  Conditional Approval of Proposed Disposition.  The CIC Shareholders'
          --------------------------------------------                        
Agent Committee and Airgas may impose any condition to their approval of any
Proposed Disposition that the CIC Shareholders' Agent Committee and Airgas
decide in their sole and absolute discretion may reduce the risk that the
Proposed Disposition could cause the Merger to fail to qualify as a
"reorganization" within the meaning of IRC (S) 368(a), including:  (a) requiring
other parties to the Proposed Disposition to execute and deliver to each of them
an instrument setting forth its specific agreement that the Airgas Shares that
are the subject of the Proposed Disposition will remain subject to this
Agreement after consummation of the Proposed Disposition; (b) requiring that any
indebtedness which is to be secured in whole or in part by the Airgas Shares
pursuant to the Proposed Disposition provide the lender full recourse against
the CIC Shareholder in an event of default; or (c) requiring that the Proposed
Disposition occur, or not occur, within a specific time frame.

     5.6  Release of Lockup/Escrow Shares From this Agreement.  In connection
          ---------------------------------------------------                
with any approval of a Proposed Disposition, the CIC Shareholders' Agent
Committee and Airgas, in their sole and complete discretion, shall also
determine whether the Airgas Shares that are the subject of the Proposed
Disposition shall remain subject to the terms and conditions of this Agreement
or, if the Proposed Disposition is consummated, shall be released from the terms
and conditions of this Agreement.  Airgas Shares released from this Agreement
shall be delivered by the Lockup/Escrow Agent to the CIC Shareholder on whose
behalf such Airgas Shares were held.

     5.7  Certain Limitation Until ______________, 1998./6/  Notwithstanding the
          ---------------------------------------------                         
foregoing, no release of Lockup/Escrow Shares with respect to any CIC
Shareholders prior to ________________, 1998 may include a number of
Lockup/Escrow Shares equal to the aggregate number of Airgas Shares that would
reduce a distribution pursuant to Section 4.1 multiplied by his Proportionate
Interest.


     5.8  Certain Permitted Transfers.  Notwithstanding the foregoing or any
          ---------------------------                                       
other provisions of this Agreement (other than Section 5.7), the CIC
Shareholders Agent Committee and Airgas shall approve any proposed sale,
transfer, gift, pledge, encumbrance, hypothecation, or other disposition of all
or any of his Lockup/Escrow Shares subject to this Agreement (a

"Proposed Permitted Disposition") described by any CIC Shareholder in writing
(in a form reasonably acceptable to the CIC Shareholders' Agent Committee and
Airgas) to the CIC Shareholders' Agent Committee and to Airgas that involves any
of the following (the "Permitted Disposition Request"):

          (a)   any transfer by the requesting CIC Shareholder outright or in
     trust or to any other entity to or for the benefit of himself, his spouse,
     or any of his lineal descendants (and in determining an individual
     shareholder's lineal descendants for this purpose, any person adopted
     according to law at any time shall thereafter for all purposes be treated
     as a child born to the one who adopts such person); provided, however, that
     the transferee adopts and joins this Agreement and provides a duly executed
     coy of a joinder and adoption instrument to Airgas and the CIC
     Shareholders' Agent Committee;

          (b)   the death of the requesting CIC Shareholder; or

          (c)   the divorce of the requesting CIC Shareholder.

The Permitted Disposition Request shall contain all the details of the Proposed
Permitted Disposition as the CIC Shareholder in good faith determines the CIC
Shareholders' Agent Committee and Airgas might need to confirm the event
required under this Section 5.8, and the CIC Shareholders' Agent Committee and
Airgas may require the CIC Shareholder to supplement the Permitted Disposition
Request with additional information that the Lockup/Escrow Agent and Airgas in
good faith determine is needed to make the determination required under this
Section.

Shareholder (who take subject to this Agreement) or except as may be determined
by the Lockup/Escrow Agent and Airgas in connection with an approved Proposed
Disposition of Lockup/Escrow Shares pursuant to Article 5 of this Agreement, no
assignment or transfer by operation of law or otherwise, in whole or in part, by
a CIC Shareholder of his rights under this Agreement shall be made.

          (b)   By Airgas.  Except with the prior written consent of the CIC
                ---------                                                   
Shareholders' Agent Committee (which shall not be unreasonably withheld or
delayed): (i) no assignment by operation of law or otherwise by Airgas of its
rights and obligations under this Agreement shall be made other than to an
entity that controls Airgas or is controlled by or is in common control with or
a successor to a substantial portion or all of the business of Airgas (but then
only if such entity expressly assumes all the obligations and liabilities of
Airgas under this Agreement either by operation of law or by specific assumption
executed by the assignee); and (ii) no transfer by operation of law or otherwise
by Airgas of a substantial part of its business shall be made unless all the
obligations and liabilities of Airgas under this Agreement are assumed in
connection with such transfer either by operation of law or by specific
assumption executed by the transferee.  In any such event, Airgas shall remain
liable for the performance of all such assigned, transferred and assumed
obligations, which liability shall be a primary obligation for full and prompt
performance rather than a secondary guarantee of collectibility of damages.

          (c)   Binding Nature. This Agreement shall be binding upon the parties

Agent Committee and Airgas by an appropriate person.  Without limiting the
foregoing or any other provision of this Agreement and without acknowledging the
necessity therefor, the CIC Shareholders shall undertake in good faith to have
any heir, descendant, beneficiary, personal representative or other successor or
assign of a deceased or incapacitated CIC Shareholder ratify and confirm the
agreements and obligations of such CIC Shareholder (including the authority of
the Lockup/Escrow Agent) under this Agreement.

          Re:  Termination Tax Opinion Under the CIC/Airgas Lockup/Escrow
               Agreement dated ____________ __, 1997 (the "Lockup/Escrow
               Agreement")

Dear Addressees:

     This letter is being provided to you pursuant to Lockup/Escrow Agreement
(S) 4.1 and is intended to be the "Termination Tax Opinion" referred to in that
section.

     A former shareholder of [the personal representative of a former
shareholder of] Carbonic Industries Corporation ("CIC") has requested our
opinion that the distribution of Airgas, Inc. ("Airgas") common stock (the
"Airgas Shares") from the Lockup/Escrow Agreement and the subsequent disposition
of any of such Airgas Shares thereby distributed from the Lockup/Escrow
Agreement will not cause the merger of CIC with and into a subsidiary of Airgas
(the "Merger"), which was effected on __________  __, 1997, to fail to qualify
as a reorganization within the meaning of section 368(a) of the Internal Revenue
Code of 1986, as amended (the "IRC").

     At the time of the Closing, McCausland, Keen & Buckman opined that the
Merger did qualify as a reorganization within the meaning of IRC (S) 368(a), and
we are relying on such opinion, including the assumption in it ( based in part
on the satisfaction of a closing condition in the merger agreement pursuant to
which the Merger was effected(the "Merger Agreement")) that CIC shareholders
receiving Airgas Shares in the Merger that represented more than fifty percent
(50%) of the Aggregate Merger Consideration in the Merger had, at the Merger
Effective Time, no plan or intent to sell, exchange or otherwise dispose of any
Airgas Shares received in the Merger.

     We have received a certificate from such requesting person (a copy of which
is attached) stating (a) that [describe the facts giving rise to the change in
circumstances] and (b) that such factual circumstances arose subsequent to the
Merger Effective Time.  We have assumed, without

                                       17

investigation, that the facts set forth in such certificate are accurate, but
to our actual knowledge, none of such facts is false nor is our reliance on
them, under the circumstances, unreasonable. When used in this letter, "to our
actual knowledge" means the current conscious awareness of facts or other
information by the lawyer in this firm who has signed this letter.

     Based upon the assumptions set forth above and the attached certificate, it
is our opinion that the distribution of the Airgas Shares from the Lockup/Escrow
Agreement and the subsequent disposition of such Airgas Shares will not cause
the Merger to fail to qualify as a reorganization within the meaning of IRC (S)
368(a).

     The opinion expressed in this letter [a] is strictly limited to the matters
stated in this letter, and without limiting the foregoing, no other opinions are
to be implied, [b] without limiting the foregoing, is being rendered solely with
respect to the federal income tax consequences of the release and disposition
specifically set forth above, and we hereby expressly disclaim any opinion as to
the treatment of such release and disposition under the income or other tax laws
of any foreign, state or local jurisdiction, and [c] speaks only as of its date;
and we are under no obligation, and do not undertake, to advise the
Lockup/Escrow Agent, Airgas, the CIC Shareholders' Agent Committee or any other
person or entity of changes of law or fact that occur after the date of this
letter, even though the change may affect the legal analysis or a legal
conclusion in this letter.

     Except as otherwise indicated in this letter, each capitalized term in
this letter has the same meaning as it has as a capitalized term in the
Lockup/Escrow Agreement and/or the Merger Agreement unless the context clearly
indicates to the contrary.

     This letter is delivered in connection with the proposed release of the
Airgas Shares from the Lockup/Escrow Agreement, may not be relied upon by the
addressees for any other purpose or by anyone else for any purpose, and may not
be quoted, published or otherwise disseminated, without in each instance our
prior written consent.

                              Very truly yours,

                    [McCausland, Keen & Buckman Letterhead]

Carbonic Industries Corporation
 and its Shareholders
3700 Crestwood Parkway, Suite 200
Duluth, Georgia 30136

Ladies and Gentlemen:

     This opinion is being furnished to you pursuant to Section 9.1(e) of the
Agreement and Plan of Reorganization by and among Airgas, Inc., a Delaware
corporation ("Airgas"), Airgas Carbonic Industries, Inc., a Delaware corporation
and wholly-owned subsidiary of Airgas ("Sub"), and Carbonic Industries
Corporation, a Florida corporation ("CIC"), dated as of March 12, 1997 (the
"Reorganization Agreement"). The Reorganization Agreement provides for the
acquisition of CIC by Airgas pursuant to a statutory merger of CIC with and into
Sub on the terms and conditions set forth in the Reorganization Agreement (the
"Merger"). Capitalized terms not defined herein shall have the meanings ascribed
to them in the Reorganization Agreement.

     We have acted as legal counsel to Airgas and Sub in connection with the
negotiation, preparation, execution and delivery of the Reorganization
Agreement. We have examined Airgas' and Sub's Articles of Incorporation, as
amended, CIC's Bylaws, Sub's Bylaws, resolutions of Airgas' and Sub's respective
Boards of Directors respecting the Reorganization Agreement, and the
transactions contemplated thereby, and such other documents as we deemed
necessary or appropriate for the purpose of rendering this opinion. As to the
due incorporation and existence in good standing of Airgas and Sub, we are
relying upon certificates, instruments and telephonic or telegraphic
communications from public and corporate officials. With respect to factual
matters, we are relying upon letters furnished to us by officers of Airgas and
Sub, as well as the representations and warranties made and expressed by Airgas
and Sub in the Reorganization Agreement and other documents delivered by CIC to
Airgas and Sub in connection with the Merger, and we have assumed that the same
are true, correct and complete as of the dates thereof and hereof. Nothing has
come to our attention that would cause us to believe that such certificates
<PAGE>

 and its Shareholders
_______________, 1997
Page 2
- --------------------------------------------------------------------------------


and letters furnished to us by officers of Airgas and Sub are not true, correct
and complete as of the dates thereof and hereof.

     In the foregoing examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals and
the authenticity of all documents submitted to us as copies of originals. Except
as set forth herein, we have made no independent examination or search of public
or corporate records or of factual matters.

     Our review of the Reorganization Agreement and the agreements, instruments
and documents delivered pursuant to the Reorganization Agreement, has been
limited to conformity with the matters relating to the corporate laws of the
State of Delaware and the United States of America, and we express no opinion
concerning conformity of the Reorganization Agreement or any agreement,
instrument or other document delivered pursuant to the Reorganization Agreement,
with the laws of any jurisdiction other than the State of Delaware and the
United States of America.

     Based upon the foregoing, we are of the opinion that:

            1. Airgas and Sub are corporations duly organized, validly existing
and in good standing under the laws of the State of Delaware and have the full
corporate power and corporate authority to carry on their respective businesses,
as they are now being conducted, and to execute and deliver the Reorganization
Agreement and the related documents called for therein and to consummate the
transactions contemplated thereby. Airgas and Sub are each qualified as a
foreign corporation in all jurisdictions in which the failure so to qualify
would have a material adverse effect on Airgas or Sub, taken as a whole.

            2. The shares of Airgas Common Stock to be issued to the CIC
Shareholders pursuant to the Reorganization Agreement, when issued in accordance
with the terms of the Reorganization Agreement, and the shares of Airgas Common
Stock issuable upon exercise of the Airgas Stock Options issued under Airgas'
1984 Stock Option Plan (the "1984 Plan") in substitution for options to acquire
shares of CIC Common Stock, when issued and paid for in accordance with the
terms of, and upon exercise of the Airgas Stock Options granted under, the 1984
Plan, will be validly issued, fully paid and nonassessable.

            3. Each of Airgas and Sub has the necessary corporate power and
authority to enter into the Reorganization Agreement and to carry out their
respective obligations thereunder. The execution and delivery of the
Reorganization Agreement by Airgas and Sub, the performance
<PAGE>
 
Carbonic Industries Corporation

Page 3
- --------------------------------------------------------------------------------

by Airgas and Sub of their respective obligations thereunder, and the
consummation by Airgas and Sub of the transactions contemplated thereby, have
been duly authorized by the respective Boards of Directors of Airgas and Sub, as
the case may be (which authorizations have not been modified and are in full
force and effect), and no other corporate proceeding on the part of Airgas or
Sub is necessary for the execution and delivery of the Reorganization Agreement
by Airgas and Sub, and, subject to the filing of the Certificate of Merger and
the Articles of Merger pursuant to Section 1.3(b) of the Reorganization
Agreement, the performance by each of Airgas and Sub of their respective
obligations thereunder and the consummation by Airgas and Sub of the
transactions contemplated thereby, does not violate any provision of the
Articles of Incorporation or the By-Laws of either Airgas or Sub, or of any law,
ordinance, regulation, rule, order, judgment, injunction or decree, does not
breach any contract, commitment, lease, agreement, instrument or other
restriction, except as described in Schedule 4.6 to the Reorganization
Agreement, or to the best of our knowledge, does not result in any penalty,
forfeiture to termination which would be materially adverse to Airgas or Sub.

            4. No filing, authorization or approval, governmental or otherwise,
is necessary to enable Airgas or Sub to enter into, and to perform each of their
obligations under, the Reorganization Agreement and the documents referenced
therein, except for (i) the filing of the Certificate of Merger and Articles of
Merger with the Delaware Secretary of State and Florida Secretary of State,
respectively, and (ii) such filings as may be required to comply with federal
and state securities laws.

            5. The shares of Airgas Common Stock to be issued to each holder of
CIC Common Stock in connection with the Merger will be issued in compliance with
the Securities Act of 1933, as amended.

            6. The Reorganization Agreement has been duly and validly executed
and delivered by Airgas and Sub. The Reorganization Agreement and each document
and instrument executed by Airgas pursuant thereto constitutes a legal, valid
and binding obligation of Airgas, enforceable in accordance with its respective
terms, except to the extent that its enforceability may be subject to
limitations imposed by general principles of equity (regardless of whether such
enforceability is considered in a proceeding at law or in equity) and to the
effect of applicable bankruptcy, reorganization, insolvency, moratorium and
similar laws of general application relating to or affecting creditors' rights
generally, including, without limitation, the effect of statutory or other laws
regarding fraudulent conveyances and preferential transfers.

- --------------------------------------------------------------------------------


            7. Neither the execution and delivery of the Reorganization
Agreement nor the consummation of the transactions contemplated thereby
constitutes a violation or default under, or conflicts with, or will result in
the creation of any lien on any of the assets owned by Airgas or Sub under, any
term or provision of the respective Articles of Incorporation or Bylaws of
Airgas or Sub, or any material agreement, including, without limitation, any
material contract, license, commitment, lease, instrument, arrangement or
understanding to which Airgas or Sub is a party or to which Airgas, Sub or any
of their respective property is subject, or by which Airgas, Sub or any of their
respective property is bound, where such lien would be materially adverse to
Airgas or Sub, taken as a whole.

     We are members of the bar of the Commonwealth of Pennsylvania and
accordingly do not express or purport to express any opinions with respect to
laws other than the laws of the Commonwealth of Pennsylvania, the General
Corporation Law of the State of Delaware and the federal laws of the United
States of America. To the extent the laws of other states would apply to any
matters that are the subject of this opinion, we have assumed, with your
consent, that the laws of such jurisdictions are the same as the laws of
Pennsylvania.

     The opinions expressed herein are rendered solely for the benefit of CIC
and may not be relied upon, used or quoted in any manner whatsoever by any other
person or entity for any purpose without the prior written consent of an officer
of this firm.

                                        Very truly yours,

          Re:  Certain Matters Relating to Carbonic Industries Corporation
               ("CIC")

Ladies and Gentlemen:

          We have acted as counsel to CIC in connection with its execution,
delivery and performance to date of that certain merger agreement by and among
CIC, Airgas, Inc., Airgas Carbonic Industries, Inc. ("Airgas") and dated as of
March __, 1997 (the "Merger Agreement") and the Lock-Up/Escrow Agreement
(together with the Merger Agreement, the "Transaction Documents") and have
participated on behalf of the CIC in connection with the transactions to date
contemplated by the Transaction Documents (the "Transaction").

          This letter is provided to you at the request of CIC pursuant to
Merger Agreement (S)9.2(e).

          Except as otherwise indicated in this letter, each capitalized term in
this letter has the same meaning as it has as a capitalized term in the Merger
Agreement unless the context clearly indicates to the contrary.

          This letter is governed by, and shall be interpreted in accordance
with, the Legal Opinion Accord (the "Accord") of the ABA Section of Business Law
(1991) as modified by Annex 1 attached to this letter (which is hereby expressly
incorporated into, and made a part of, this letter). As a consequence, this
letter is subject to a number of qualifications, exceptions, definitions,
limitations on coverage and other limitations, all as more particularly
described in the Accord and such Annex 1, and this letter should be read in
conjunction with such.

          The opinions herein are limited to: (i) Georgia law; (ii) to the
extent applicable, the corporation laws of the States of Florida and Delaware
and such corporation laws shall be deemed to consist solely of the provisions of
the Florida Business Corporation Act and General Corporation Law of the State of
Delaware, in each case without annotations, appearing in Corporations--Covering
                                                         ----------------------
Corporation Practice-Procedure-Law published by Prentice Hall Information
- ----------------------------------                                       
Services as, respectively, the Florida Business Corporation Act (the "Florida
<PAGE>
 
Airgas, Inc.

Page 2

Corporation Laws") and the Delaware General Corporation Laws (the "Delaware
Corporation Laws"); and (iii) the federal law of the United States.  We further
call Airgas's attention to the fact that the Merger Agreement provides that it
shall be governed by the laws of the State of Delaware, other than approvals of
certain corporate approvals and filings which shall be governed by the corporate
laws of the State of Florida and the State of Delaware as appropriate.  We are
not experts on such laws and do not purport to express in this letter our
opinions with respect to them, including the enforceability of any contractual
choice of law provisions but, rather (and except as set forth in clause (ii) of
the first sentence of this paragraph), have assumed that Delaware law is
identical in all respects to Georgia law.

          In connection with this letter, we have reviewed copies of each of the
Transaction Documents executed by CIC, and we have reviewed such other documents
and given consideration to such matters of law and fact as we have deemed
appropriate, in our professional judgment, to render the opinions expressed in
this letter.  We have relied upon factual representations made by CIC in the
Merger Agreement and made by CIC in a certificate of CIC's officers delivered to
us ("Officers' Certificate"), in each case without any independent investigation
of them, but to our actual knowledge, none of such factual representations is
false nor is our reliance on them, under the circumstances, unreasonable.  When
used in this letter, "to our actual knowledge" means the current conscious
awareness of facts or other information by the lawyers in this firm who have
signed this letter or who have had active involvement in negotiating the
Transaction, preparing the Transaction Documents or this letter, and solely as
to information relevant to a particular opinion issue or confirmation regarding
a particular factual matter, who are primarily responsible for providing the
response concerning that particular opinion issue or confirmation.

          Based on and subject to the foregoing, we are of the opinion that:

          1.   CIC, based solely on a Certificate of Existence issued by the
     Secretary of State of the State of Florida dated ___________ __, 1997 (and
     we have assumed that it was given on the date of this letter) is duly and
     validly existing and in good standing under the Florida Corporation Laws.

          2.   CIC has the corporate power and authority to own or lease its
     properties and to engage generally in the carbon dioxide manufacture and
     distribution business.

          3.   Based solely upon our review of CIC's articles of incorporation,
     bylaws, corporate minutes and share records and the Officers' Certificate:

               (a)  CIC's authorized capital consists of 1,000,000 Class A
     common shares, par value $2.00 per share, of which 903,993 shares are
     issued and outstanding and 25,000 Class B common shares, par value $2.00
     per share, of which 25,000 shares are issued and outstanding (such issued
     and outstanding shares being referred to in this letter as the "CIC
     Shares"); and there are no authorized or outstanding calls, options or
     other rights, commitments, undertakings or understandings to acquire any
     CIC Shares or other capital shares or equity interests of CIC or
     obligations convertible into CIC Shares or other capital shares or other
     equity interests of any kind or class of CIC or securities of any kind or
     class of CIC; and

               (b)  no provision of CIC's articles of incorporation or bylaws
     will prevent any CIC Shareholder from voting his, her or its shares in
     favor of the Transaction.

          4.   The execution and delivery by CIC of, and performance on or
     before the Closing by CIC of its agreements in, the Transaction Documents
     do not and will not, with lapse of time or giving of notice or both: (a)
     violate CIC's articles of incorporation or bylaws as in effect on the date
     of this letter; (b) breach, or result in a default under, any existing
     obligation of CIC under any agreement to which it is a party and which is
     listed in the CIC Disclosure Schedule; or (c) breach or otherwise violate
     any existing obligation of CIC under any court or administrative order,
     writ, judgment or decree that names CIC and is listed in the CIC Disclosure
     Schedule.

          5.   The execution and delivery by CIC of, and performance by CIC of
     its agreements in, the Transaction Documents neither is prohibited by, nor
     subjects CIC to a fine, penalty or other similar sanction under, any
     statute or regulation directly applicable to CIC or the Transaction.

          6.   If, notwithstanding the parties' choice of the law of the State
     of Delaware as the governing law of the Transaction Documents, a court were
     to apply the law of the State of Georgia to it, then (assuming that the law
     of the State of Delaware is identical in all respects to the law of the
     State of Georgia) each Transaction Document would be enforceable against
     CIC Shareholders in accordance with its terms.

          7.   Upon the filing of the Certificate of Merger with the Secretary
     of State of the State of Florida and the Secretary of the State of Delaware
     in accordance with Merger Agreement (S)1.3, the Merger shall become
     effective, and without limiting the foregoing, CIC Shares shall thereupon
     be converted as provided in Merger Agreement Article 2.

                                                                MERGER AGREEMENT



                   [McCausland, Keen & Buckman, Letterhead]


                            ________________, 1997


Airgas, Inc.
259 Radnor-Chester Road, Suite 100
Radnor, Pennsylvania 19087-5240

Carbonic Industries Corporation and its Shareholders
1610 South Division Avenue
Orlando, Florida 32805-4755

Ladies and Gentlemen:

     This opinion is being delivered to you in connection with the Agreement and
Plan of Merger (the "Agreement") by and among Airgas, Inc., a Delaware
corporation ("Parent"), Airgas Carbonic Industries, Inc., a Delaware corporation
("Sub") and Carbonic Industries Corporation, a Florida corporation ("CIC"),
dated March 12, 1997. Pursuant to the Agreement CIC will merge with and into Sub
(the "Merger"), and Sub will be the surviving corporation in the Merger.

     Except as otherwise provided, capitalized terms referred to herein have the
meanings set forth in the Merger Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

     We have acted as legal counsel to Parent and Sub in connection with the
Merger. As such, and for the purpose of rendering this opinion, we have examined
and are relying upon (without any independent investigation or review thereof)
the truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents:

     1.  The Agreement;

     2.  The Registration Statement on Form S-4 (File No. 333-       ),
including the Proxy Statement/Prospectus included therein (the "Registration
Statement";

     3.  Representations made to us by Parent and Sub in a letter reproduced as
Exhibit A hereto;
<PAGE>
 
     4.  Representations made to us by CIC in a letter reproduced as Exhibit B
hereto (the "CIC Representation Letter");

     5.  Representations made by certain stockholders of CIC (the
"Representative CIC Stockholders") contained in certain continuity of interest
certificates delivered by them to Parent pursuant to the closing condition in
Section 9.3(f) of the Agreement (the "Continuity of Interest Certificates"),
which form of certificate is reproduced as Exhibit C hereto ; and

     6.  Such other instruments and documents related to the formation,
organization and operation of Parent, Sub and CIC or to the consummation of the
Merger and the transactions contemplated thereby as we have deemed necessary or
appropriate.

     In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

     A.  Original documents (including signatures) are authentic and documents
submitted to us as copies conform to the original documents, and there has been
(or will be by the Merger Effective Time) due execution and delivery of all
documents where due execution and delivery are prerequisites to effectiveness
thereof;

     B.  The Merger will be effective under the laws of the States of Delaware
and Florida;

     C.  Based on those certain representations of CIC and the Representative
CIC Stockholders as provided in the CIC Representation Letter and Continuity of
Interest Certificates, respectively, and the assumptions made in the last and
next to last sentences of this Paragraph C, there does not exist as of the
Merger Effective Time any plan or intention of CIC stockholders to sell,
exchange, or otherwise dispose of a number of shares of Parent common stock
received in the Merger that would reduce the CIC stockholders' ownership of
Parent common stock to a number of shares having a value, as of the Merger
Effective Time, of less than 50 percent of the value of all of the formerly
outstanding capital stock of CIC immediately prior to the Merger Effective Time.
For this purpose, shares of CIC capital stock exchanged for cash or other
property, (including without limitation, cash received pursuant to the
perfection of dissenters' rights) will be treated as outstanding CIC capital
stock immediately prior to the Merger Effective Time. Moreover for this purpose,
shares of CIC capital stock and shares of Parent common stock held by CIC
stockholders and otherwise sold, redeemed, or disposed of prior or subsequent to
the Merger Effective Time have been and will be considered.

     D.  No outstanding indebtedness of CIC represents equity for tax purposes;
no outstanding equity of CIC represents indebtedness for tax purposes; no
outstanding indebtedness of CIC represents indebtedness of a CIC stockholder for
tax purposes.

Based on our examination of the foregoing items and subject to the assumptions,
exceptions, limitations and qualifications set forth herein, we are of the
opinion that, for federal income tax
<PAGE>
 
purposes, the Merger will be a "reorganization" as defined in Section 368(a) of
the Code, the exchange of CIC capital stock by the CIC stockholders solely for
Parent common stock, subject to the representations expressed below, will be an
exchange described in Section 354 of the Code, neither Parent, Sub nor CIC will
recognize gain or loss as a result of the Merger, and no gain or loss will be
recognized by CIC stockholders for federal income tax purposes with respect to
their receipt of Parent Common Stock in exchange for their CIC capital stock.

     In addition to the assumptions set forth above, this opinion is subject to
the exceptions, limitations and qualifications set forth below.

     1.  This opinion represents and is based upon our best judgment regarding
the application of federal income tax laws arising under the Code, existing
judicial decisions, administrative regulations and published rulings and
procedures. Our opinion is not binding upon the Internal Revenue Service or the
courts, and there is no assurance that the Internal Revenue Service will not
assert a contrary position. Furthermore, no assurance can be given that future
legislative, judicial or administrative changes, on either a prospective or
retroactive basis, would not adversely affect the accuracy of the conclusions
stated herein. Nevertheless, we undertake no responsibility to advise you of any
new developments in the application or interpretation of the federal income tax
laws.

     2.  This opinion addresses only the matters specifically set forth above
and does not address any other federal, state, local or foreign tax consequences
that may result from the Merger or any other transaction. In particular, we
express no opinion regarding (i) whether and the extent to which any CIC
stockholder who has provided or will provide services to Parent or Sub will have
compensation income under any provision of the Code; (ii) the effects of such
compensation income, including but not limited to the effect upon the basis and
holding period of the Parent common stock received by any such CIC stockholder
in the Merger; (iii) the potential application of the "golden parachute"
provisions (sections 280G, 3121(v)(2) and 4999) of the Code, the alternative
minimum tax provisions (sections 55, 56 and 57) of the Code or sections 357 and
424 of the Code, or the regulations promulgated thereunder; (iv) the corporate-
level post-Merger tax consequences to Parent, Sub or CIC, including without
limitation, the survival and/or availability, after the Merger, of any of the
federal income tax attributes or elections of CIC and Sub after application of
any provision of the Code, as well as the regulations promulgated thereunder and
judicial interpretations thereof; (v) the basis of any equity interest in Parent
common stock acquired by CIC stockholders in the Merger; (vi) the tax
consequences of any transaction in which a right to acquire Parent common stock
was received; and (vii) the tax consequences of the Merger as applied to
specific stockholders of CIC and/or holders of options or warrants for CIC
capital stock.

     3.  No opinion is expressed as to any transaction other than the Merger as
described in the Agreement or to any transaction whatsoever, including the
Merger, if all the transactions described in the Agreement are not consummated
in accordance with the terms of such Agreement and without waiver or breach of
any material provision thereof (including, without limitation the terms and
provisions of Sections 9.3 (a) and (f) of the Agreement), or if all of the
representations, warranties, statements and assumptions upon which we relied are
not true and accurate at all relevant
<PAGE>
 
times.  In the event any one of the statements, representations, warranties or
assumptions upon which we have relied to issue this opinion is incorrect, our
opinion might be adversely affected and may not be relied upon.

     4.  This opinion has been delivered to you for the purpose of satisfying
the condition set forth in Section  9.3(g) of the Agreement and is intended
solely for your benefit; it may not be relied upon for any other purpose or by
any other person or entity, and may not be made available to any other person or
entity without our prior written consent.


                                               Very truly yours,

                                               McCausland, Keen & Buckman

Radnor, Pennsylvania 19087-5240


          RE:   Merger pursuant to Agreement and Plan of Merger (the
                "Agreement") dated March 12, 1997, by and among Airgas, Inc., a
                Delaware corporation ("Parent"), Airgas Carbonic Industries,
                Inc., a Delaware corporation ("Sub") and Carbonic Industries
                Corporation, a Florida corporation ("CIC")
                ---------------------------------------------------------------

Ladies and Gentlemen:

     This letter is supplied to you in connection with your rendering of an
opinion regarding certain federal income tax consequences of the Merger (as
defined in Section 9.3(g) of the Agreement). Unless otherwise defined herein,
capitalized terms not defined herein shall have the meanings set forth in the
Agreement.

     A.   Representations.  After consulting with its counsel and auditors
          ---------------                                                 
regarding the meaning of and factual support for the following representations,
the undersigned hereby certify and represent that the following facts are true
as of the Merger Effective Time:

     1.   Except as described in the attached schedule, the Merger will be
consummated in compliance with the material terms of the Agreement and none of
the material terms and conditions therein have been waived or modified and
Parent and Sub have no plan or intention to waive or modify further any such
material term or condition.

     2.   The ratio for exchange of shares of capital stock of CIC for common
stock of Parent in the Merger was negotiated through arm's length bargaining.
Accordingly, the undersigned believes that the fair market value of the Parent
common stock and cash consideration to be received by CIC stockholders in the
Merger will be approximately equal to the fair market value of the CIC capital
stock surrendered by CIC stockholders in exchange therefor.

     3.   The total fair market value of all consideration other than Parent's
common stock received by CIC's stockholders in the Merger (including, without
limitation, cash paid to CIC's stockholders perfecting dissenters' rights) will
be less than fifty percent (50%) of the aggregate fair market value of CIC's
capital stock outstanding immediately prior to the Merger.
<PAGE>
 
McCausland, Keen & Buckman

     4.   Prior to the Merger, Parent will be in "Control" of Sub.  As used
herein, "Control" shall consist of direct ownership of stock possessing at least
Eighty Percent (80%) of the total combined voting power of all classes of stock
entitled to vote and at least Eighty Percent (80%) of the total number of shares
of all other classes of stock of Sub. For purposes of determining "Control", a
person shall not be considered  to own voting stock  if  rights to vote such
stock (or to restrict or otherwise control the voting of such stock) are held by
a third party (including a voting trust) other than an agent of such person.

     5.   The management of Parent and Sub have no knowledge of, and believe
that there does not exist any plan or intention by the CIC stockholders to sell,
exchange, or otherwise dispose of a number of shares of Parent common stock
received in the Merger that would reduce the CIC stockholders' ownership of
Parent common stock to a number of shares having a value, as of the date of the
Merger, of less than 50 percent of the value of all of the formerly outstanding
capital stock of CIC immediately prior to the Merger.  For purposes of this
representation, shares of CIC capital stock exchanged for cash or other
property, (including without limitation, cash received pursuant to the
perfection of dissenters' rights) will be treated as outstanding CIC capital
stock immediately prior to the Merger.  Moreover, shares of CIC capital stock
and shares of Parent common stock held by CIC stockholders and otherwise sold,
redeemed, or disposed of prior or subsequent to the transaction will be
considered in making this representation.  In addition, the management of Parent
and Sub are not aware of any transfers of CIC capital stock by any holders
thereof prior to the Merger Effective Time which were made in contemplation of
the Merger.

     6.   As a result of the Merger, CIC will transfer to Sub at least ninety
percent (90%) of the fair market value of the net assets and at least seventy
percent (70%) of the fair market value of the gross assets of CIC held by it
immediately prior to the Merger.  For this purpose, amounts used to pay CIC
stockholders perfecting dissenters' rights or to pay reorganization expenses,
and all redemptions and distributions (except for regular, normal dividends)
made by CIC during the period beginning on the date of commencement of
negotiations between Parent and CIC regarding the Merger and ending at the
Merger Effective Time (the "Pre-Merger Period") will be considered as assets
held by CIC immediately prior to the Merger.

     7.   The assumption by Sub of the liabilities of CIC pursuant to the Merger
is for a bona fide business purpose and the principal purpose of such assumption
is not the avoidance of federal income tax on the transfer of assets of CIC to
Sub pursuant to the Merger.

     8.   No liabilities of any person other than CIC will be assumed by Sub or
Parent in the Merger, and none of the shares of capital stock of CIC to be
surrendered in exchange for Parent common stock in the Merger will be subject to
any liabilities.

     9.   Parent has no plan or intention to cause Sub to issue additional
shares of stock after the Merger that would result in Parent losing Control of
Sub. In addition thereto, Parent has no plan or intention to reaquire any of its
stock issued pursuant to the Merger.

     10.  Except for transfers described in both Section 368(a)(2)(C) of the
Internal Revenue Code of 1986, as amended ("Code") and Treas. Reg. (S)1.368-
2(j)(4), Parent has no plan or intention to liquidate Sub, to merge Sub into
another corporation or entity, to sell, distribute or otherwise dispose of the
stock of Sub, or to cause Sub to sell or otherwise dispose of any its assets
except for dispositions made in the ordinary course of business or payment of
expenses incurred by Sub pursuant to the Merger.

     11.  Parent intends that following the Merger, Sub will continue CIC's
historic business or use a significant portion of CIC's historic business assets
in a business.

     12.  Parent and Sub will pay their respective expenses, if any, incurred in
connection with the Merger. Neither Parent nor Sub will pay any of the expenses
of the stockholders of CIC incurred in connection with the Merger.

     13.  There is no intercorporate indebtedness existing between Parent and
CIC or between Sub and CIC that was issued, acquired, or will be settled at a
discount.

     14.  Neither Parent nor Sub is an investment company as defined in Sections
368(a)(2)(F)(iii) and (iv) of the Code.

     15.  Neither Parent nor Sub is under the jurisdiction of a court in a Title
11 or similar case within the meaning of Section 368(a)(3)(A) of the Code.

     16.  No stock of Sub will be issued to the CIC stockholders in the Merger.

     17.  None of the compensation received by any stockholder-employee of CIC
pursuant to any employment, consulting or similar arrangement with Parent or Sub
will be separate consideration for, or allocable to, any of his shares of CIC
capital stock. None of the shares of common stock of Parent received by any
stockholder-employee of CIC pursuant to the Merger are or will be separate
consideration for, or allocable to, any such employment, consulting or similar
arrangement. The compensation paid to any stockholder-employee of CIC pursuant
to any such employment consulting or similar arrangement is or will be for
services actually rendered and will be commensurate with amounts paid to third
parties bargaining at arm's length for similar services.

McCausland, Keen & Buckman
Radnor Court
259 Radnor-Chester Road, Suite 160
Radnor, Pennsylvania 19087-5240

          RE:   Merger pursuant to Agreement and Plan of Merger (the
                "Agreement") dated March 12, 1997, by and among Airgas, Inc., a
                Delaware corporation ("Parent"), Airgas Carbonic Industries,
                Inc., a Delaware corporation ("Sub") and Carbonic Industries
                Corporation, a Florida corporation ("CIC")
                               ----------------------------------------
Ladies and Gentlemen:

          This letter is supplied to you in connection with your rendering of an
opinion regarding certain federal income tax consequences of the Merger (as
defined in Section 9.3 (g)of the Agreement). Unless otherwise defined herein,
capitalized terms not defined herein shall have the meanings set forth in the
Agreement.

          A.  Representations.  After consulting with its counsel and auditors
              ---------------                                                 
regarding the meaning of and factual support for the following representations,
the undersigned hereby certifies and represents that the following facts are
true as of the Merger Effective Time.

          1.  Except as described in the attached schedule, the Merger will be
consummated in compliance with the material terms of the Agreement and none of
the material terms and conditions therein have been waived or modified and CIC
has no plan or intention to waive or modify further any such material term or
condition.

          2.  The ratio for exchange of shares of capital stock of CIC for
common stock of Parent in the Merger was negotiated through arm's length
bargaining.  Accordingly, the undersigned believes that the fair market value of
the Parent common stock and cash consideration to be received by CIC
stockholders in the Merger will be approximately equal to the fair market value
of the CIC capital stock surrendered by CIC stockholders in exchange therefor.

          3.  Consistent with Paragraph 1 above, the total fair market value of
all consideration other than Parent's common stock received by CIC's
stockholders in the Merger (including, without limitation, cash paid to CIC's
stockholders perfecting dissenters' rights) will be less than fifty percent
(50%) of the aggregate fair market value of CIC's capital stock outstanding
immediately prior to the Merger.
<PAGE>
 
McCausland, Keen & Buckman
___________________, 1997
Page 2

          4.  Other than shares of CIC capital stock or options to acquire CIC
capital stock issued to present or former service providers (including, without
limitation, employees and directors) of CIC in the ordinary course of business,
no issuance of CIC's capital stock has occurred or will occur during the period
beginning on the date of commencement of negotiations between Parent and CIC
regarding the Merger and ending at the Merger Effective Time (the "Pre-Merger
Period"), other than pursuant to options, warrants or agreements outstanding
prior to the Pre-Merger Period or issued in the ordinary course of business
during the Pre-Merger Period.

          5.  Based on inquiry of those persons listed in Section 11.6 of the
Agreement (the "Management of CIC"), CIC has no knowledge of, and believes that
there does not exist any plan or intention by the CIC stockholders to sell,
exchange, or otherwise dispose of a number of shares of Parent common stock
received in the Merger that would reduce the CIC stockholders' ownership of
Parent common stock to a number of shares having a value, as of the date of the
Merger, of less than 50 percent of the value of all of the formerly outstanding
capital stock of CIC immediately prior to the Merger.  For purposes of this
representation, shares of CIC capital stock exchanged for cash or other property
(including without limitation, cash received pursuant to the perfection of
dissenters' rights) will be treated as outstanding CIC capital stock immediately
prior to the Merger.  Moreover, shares of CIC capital stock and shares of Parent
common stock held by CIC stockholders and otherwise sold, redeemed, or disposed
of prior or subsequent to the transaction will be considered in making this
representation.  In addition, the Management of CIC is not aware of any
transfers of CIC capital stock by any holders thereof prior to the Merger
Effective Time which were or will be made in contemplation of the Merger.

          6.  As a result of the Merger, CIC will transfer to Sub at least
ninety percent (90%) of the fair market value of the net assets and at least
seventy percent (70%) of the fair market value of the gross assets of CIC held
by it immediately prior to the Merger.  For this purpose, amounts used to pay
CIC stockholders perfecting dissenters' rights or to pay reorganization
expenses, and all redemptions and distributions (except for regular, normal
dividends) made by CIC during the "Pre-Merger Period" will be considered as
assets held by CIC immediately prior to the Merger.  CIC has not redeemed any of
the CIC capital stock, made any distribution with respect to any of the CIC
capital stock, or disposed of any of its assets in anticipation of or as a part
of a plan for the acquisition of CIC by Sub pursuant to the Merger.

          7.  To CIC's knowledge, the assumption by Sub of the liabilities of
CIC pursuant to the Merger is for a bona fide business purpose and the principal
purpose of such assumption is not the avoidance of federal income tax on the
transfer of assets of CIC to Sub pursuant to the Merger.

          8.  The liabilities of CIC assumed by Sub and the liabilities to which
the transferred assets CIC are subject were incurred by CIC in the ordinary
course of its business.  No liabilities of any

McCausland, Keen & Buckman

person other than CIC will be assumed by Sub or Parent in the Merger.

          9.  Parent, Sub and CIC will pay their respective expenses, if any,
incurred in connection with the Merger.  None of Parent, Sub, and CIC will pay
any of the expenses of the stockholders of CIC incurred in connection with the
Merger.

          10.  There  is no intercorporate indebtedness existing between Parent
and CIC or between Sub and CIC that was issued, acquired, or will be settled at
a discount.

          11.  CIC is not an investment company as defined in Section
368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as amended (the
"Code").

          12.  CIC is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

          13.  On the date of the Merger, the fair market value of the assets of
CIC will exceed the sum of its liabilities (including any liabilities to which
its assets are subject).

          14.  None of the compensation received by any stockholder-employee of
CIC pursuant to any employment, consulting or similar arrangement (including
Controlling Shareholder Employment Agreement) is or will be separate
consideration for, or allocable to, any of his shares of CIC capital stock.
None of the shares of common stock of Parent received by any stockholder-
employee of CIC pursuant to the Merger are or will be separate consideration
for, or allocable to, any such employment, consulting or similar arrangement.
The compensation paid to any stockholder-employee of CIC pursuant to any such
employment consulting or similar arrangement is or will be for services actually
rendered and will be commensurate with amounts paid to third parties bargaining
at arm's length for similar services.
 
          15.  CIC is authorized to make all of the representations set forth
herein.

          B.   Reliance by You in Rendering Opinion; Limitations on Your
               ---------------------------------------------------------
               Opinion.
               -------

          1.   CIC recognizes that (i) your opinion will be based on the
representations set forth herein and on the statements contained in the
Agreement and documents related thereto, and (ii) your opinion will be subject
to certain limitations and qualifications including that they may not be relied
upon if any such representations are not accurate in all material respects.

5.   Importance of Certificate
     -------------------------

     I represent that the statements contained in this certificate are true and
     accurate.  I understand that the truthfulness and accuracy of this
     certificate is important to achieving the tax treatment of the Merger
     described in the Proxy Statement and Prospectus.

     I also understand that the parties to the Merger and their respective
     counsel are in part relying on the truth an accuracy of this certificate as
     well as the certificates of the other CIC shareholders to conclude that the
     Merger is a reorganization within the meaning of the Internal Revenue code.

     deemed appropriate to assist me in filling out this certificate (but I did
     not obtain any such counsel if I did not feel it was necessary).

6.   Obligation to Notify CIC of Changes.
     ----------------------------------- 

     I will notify CIC in writing prior to the time that the Merger becomes
     effective of any changes in my intentions or my ownership of CIC or Airgas
     shares that would make any information contained in this certificate untrue
     or inaccurate.  I will send such notice to CIC at ________________________,
     ____________.

                 Florida Statutes Governing Dissenters' Rights


607.1301.    Dissenters' rights; definitions

      The following definitions apply to (S)(S) 607.1302 and 607.1320:

shareholder before the corporate action or the surviving or acquiring
corporation by merger or share exchange of that issuer.

      (2)    "Fair value," with respect to a dissenter's shares, means the
value of the shares as of the close of business on the day prior to the
shareholders' authorization date, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

      (3)    "Shareholders' authorization date" means the date on which the
shareholders' vote authorizing the proposed action was taken, the date on which
the corporation received written consents without a meeting from the requisite
number of shareholders in order to authorize the action, or, in the case of a
merger pursuant to (S) 607.1104, the date prior to the date on which a copy of
the plan of merger was mailed to each shareholder of record of the subsidiary
corporation.

607.1302.    Right of shareholders to dissent

      (1)    Any shareholder of a corporation has the right to dissent from, and
obtain payment of the fair value of his shares in the event of, any of the
following corporate actions:

             (a)    Consummation of a plan of merger to which the corporation is
a party:
                    1.     If the shareholder is entitled to vote on the merger,
or

                    2.     If the corporation is a subsidiary that is merged

exchange pursuant to (S) 607.1202, including a sale in dissolution but not
including a sale pursuant to court order or a sale for cash pursuant to a plan
by which all or substantially all of the net proceeds of the sale will be
distributed to the shareholders within 1 year after the date of sale;
<PAGE>
 
             (c)    As provided in (S) 607.0902(11), the approval of a control-
share acquisition;

             (d)    Consummation of a plan of share exchange to which the

             (e)    Any amendment of the articles of incorporation if the
shareholder is entitled to vote on the amendment and if such amendment would
adversely affect such shareholder by:

                    1.    Altering or abolishing any preemptive rights attached
to any of his shares;

                    2.    Altering or abolishing the voting rights pertaining to
any of his shares, except as such rights may be affected by the voting rights of
new shares then being authorized of any existing or new class or series of
shares;

                    3.    Effecting an exchange, cancellation, or
reclassification of any of his shares, when such exchange, cancellation, or
reclassification would alter or abolish his voting rights or alter his
percentage of equity in the corporation, or affecting a reduction or
cancellation of accrued dividends or other arrearages in respect to such shares;

                    4.    Reducing the stated redemption price of any of his
redeemable shares, altering or abolishing any provision relating to any sinking
fund for the redemption or purchase of any of his shares, or making any of his
shares subject to redemption when they are not otherwise redeemable;

                    5.    Making noncumulative, in whole or in part, dividends
of any of his preferred shares which had theretofore been cumulative;

preferred shares; or

                    7.    Reducing any stated preferential amount payable on any
of his preferred shares upon voluntary or involuntary liquidation; or

             (f)    Any corporate action taken, to the extent the articles of
incorporation provide that a voting or nonvoting shareholder is entitled to
dissent and obtain payment for his shares.

      (2)    A shareholder dissenting from any amendment specified in paragraph
(1)(e) has the right to dissent only as to those of his shares which are
adversely affected by the amendment.

      (3)    A shareholder may dissent as to less than all the shares
registered in his name.  In the event, his rights shall be determined as if the
shares as to which he has dissented and his other shares were registered in the
names of different shareholders.

      (4)    Unless the articles of incorporation otherwise provide, this
section does not apply with respect to a plan of merger or share exchange or a
proposed sale or exchange of property, to the holders of shares of any class or
series which, on the record date fixed to determine the shareholders entitled to
vote at the meeting of shareholders at which such action is to be acted upon or
to consent to any such action without a meeting, were either registered on a
national securities exchange or designated as a national market system security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc., or held of record by not fewer than 2,000 shareholders.

      (5)    A shareholder entitled to dissent and obtain payment for his shares
under this section may not challenge the corporate action creating his
entitlement unless the action is unlawful or fraudulent with respect to the
shareholder or the corporation.

607.1320.    Procedure for exercise of dissenters' rights

      (1)    (a)   If a proposed corporate action creating dissenters' rights
under (S) 607.1302 is submitted to a vote at a shareholders' meeting, the
meeting notice shall state that shareholders are or may be entitled to assert
dissenters' rights and be accompanied by a copy of (S)(S) 607.1301, 607.1302,
and 607.1320.  A shareholder who wishes to assert dissenters' rights shall:

                   1.   Deliver to the corporation before the vote is taken
written notice of his intent to demand payment for his shares if the proposed
action is effectuated, and

                   2.   Note vote his shares in favor of the proposed action. A
proxy or vote against the proposed action does not constitute such a notice of
intent to demand payment.

             (b)   If proposed corporate action creating dissenters' rights
under (S) 607.1302 is effectuated by written consent without a meeting, the
corporation shall deliver a copy of (S)(S) 607.1301, 607.1302, and 607.1320 to
each shareholder simultaneously with any request for his written consent or, if
such a request is not made, within 10 days after the date the corporation
received written consents without a meeting from the requisite number of
shareholders necessary to authorize the action.

      (2)    Within 10 days after the shareholders' authorization date, the
corporation shall give written notice of such authorization or consent or
adoption of the plan of merger, as the case may be, to each shareholder who
filed a notice of intent to demand payment for his shares pursuant to paragraph
(1)(a) or, in the case of action authorized by written consent, to each
shareholder, excepting any who voted for, or consented in writing to, the
proposed action.

      (3)    Within 20 days after the giving of notice to him, any shareholder
who elects to dissent shall file with the corporation a notice of such election,
stating his name and address, the number, classes, and series of shares as to
which he dissents, and a demand for payment of the fair value of his shares.
Any shareholder failing to file such election to dissent within the period set
forth shall be bound by the terms of the proposed corporate action.  Any
shareholder filing an election to dissent shall deposit his certificates for
certificated shares with the corporation simultaneously with the filing

                                      -3-
<PAGE>
 
of the election to dissent.  The corporation may restrict the transfer of
uncertificated shares from the date the shareholder's election to dissent is
filed within the corporation.

      (4)  Upon filing a notice of election to dissent, the shareholder shall
thereafter be entitled only to payment as provided in this section and shall not
be entitled to vote or to exercise any other rights of a shareholder.  A notice
of election may be withdrawn in writing by the shareholder at any time before an
offer is made by the corporation, as provided in subsection (5), to pay for his
shares. After such offer, no such notice of election may be withdrawn unless the
corporation consents thereto.  However, the right of such shareholder to be paid
the fair value of his shares shall cease, and he shall be reinstated to have all
his rights as a shareholder as of the filing of his notice of election,
including any intervening preemptive rights and the right to payment of any
intervening dividend or other distribution or, if any such rights have expired
or any such dividend or distribution other than in cash has been completed, in
lieu thereof, at the election of the corporation, the fair value thereof in cash
as determined by the board as of the time of such expiration or completion, but
without prejudice otherwise to any corporate proceedings that may have been
taken in the interim, if:

           (a)   Such demand is withdrawn as provided in this section;

           (b)   The proposed corporate action is abandoned or rescinded or the
shareholders revoke the authority to effect such action;

           (c)   No demand or petition for the determination of fair value by a
court has been made or filed within the time provided in this section; or

           (d)   A court of competent jurisdiction determines that such
shareholder is not entitled to the relief provided by this section.

      (5)  Within 10 days after the expiration of the period in which
shareholders may file their notices of election to dissent, or within 10 days
after such corporate action is effected, whichever is later (but in no case
later than 90 days from the shareholders' authorization date), the corporation
shall make a written offer to each dissenting shareholder who has made demand as
provided in this section to pay an amount the corporation estimates to be the
fair value for such shares.  If the corporate action has not been consummated
before the expiration of the 90-day period after the shareholders' authorization
date, the offer may be made conditional upon the consummation of such action.
Such notice and offer shall be accompanied by:

           (a)   A balance sheet of the corporation, the shares of which the
dissenting shareholder holds, as of the latest available date and not more than
12 months prior to the making of such offer; and

           (b)   A profit and loss statement of such corporation for the 12-
month period ended on the date of such balance sheet or, if the corporation was
not in existence throughout such 12-month period, for the portion thereof during
which it was in existence.

                                      -4-
<PAGE>
 
      (6)  If within 30 days after the making of such offer any shareholder
accepts the same, payment for his shares shall be made within 90 days after the
making of such offer or the consummation of the proposed action, whichever is
later.  Upon payment of the agreed value, the dissenting shareholder shall cease
to have any interest in such shares.

      (7)  If the corporation fails to make such offer within the period
specified therefor in subsection (5) or if it makes the offer and any dissenting
shareholder or shareholders fail to accept the same within 30 days after receipt
of written demand from any dissenting shareholder given within 60 days after the
date on which such corporate action was effected, shall, or at its election at
any time within such period of 60 days may, file an action in any court of
competent jurisdiction in the county in this state where the registered office
of the corporation is located requesting that the fair value of such shares be
determined.  The court shall also determine whether each dissenting shareholder,
as to whom the corporation requests the court to make such determination, is
entitled to receive payment for his shares.  If the corporation fails to
institute the proceeding as herein provided, any dissenting shareholder may do
so in the name of the corporation.  All dissenting shareholders (whether or not
residents of this state), other than shareholders who have agreed with the
corporation as to the value of their shares, shall be made parties to the
proceeding as an action against their shares.  The corporation shall serve a
copy of the initial pleading in such proceeding upon each dissenting shareholder
who is a resident of this state in the manner provided by law for the service of
a summons and complaint and upon each nonresident dissenting shareholder either
by registered or certified mail and publication or in such other manner as is
permitted by law.  The jurisdiction of the court is plenary and exclusive.  All
shareholders who are proper parties to the proceeding are entitled to judgment
against the corporation for the amount of the fair value of their shares.  The
court may, if it so elects, appoint one or more persons as appraisers to receive
evidence and recommend a decision on the question of fair value.  The appraisers
shall have such power and authority as is specified in the order of their
appointment or an amendment thereof.  The corporation shall pay each dissenting
shareholder the amount found to be due him within 10 days after final
determination of the proceedings.  Upon payment of the judgment, the dissenting
shareholder shall cease to have any interest in such shares.

      (8)  The judgment may, at the discretion of the court, include a fair rate
of interest, to be determined by the court.

      (9)  The costs and expenses of any such proceeding shall be determine by
the court and shall be assessed against the corporation, but all or any part of
such costs and expenses may be apportioned and assessed as the court deems
equitable against any or all of the dissenting shareholders who are parties to
the proceeding, to whom the corporation has made an offer to pay for the shares,
if the court finds that the action of such shareholders in failing to accept
such offer was arbitrary, vexatious, or not in good faith. Such expenses shall
include reasonable compensation for, and reasonable expenses of, the appraisers,
but shall exclude the fees and expenses of counsel for, and experts employed by,
any party. If the fair value of the shares, as determined, materially exceeds
the amount which the corporation offered to pay therefor or if no offer was
made, the court in its discretion may award to any shareholder who is a party to
the proceeding such sum as the court determines to be reasonable compensation to
any attorney or expert employed by the shareholder in the proceeding.

      (10)  Shares acquired by a corporation pursuant to payment of the agreed
value thereof or pursuant to payment of the judgment entered therefore, as
provided in this section, may be held and disposed of by such corporation as
authorized but unissued shares of the corporation, except that, in the case of a
merger, they may be held and disposed of as the plan of merger otherwise
provides. The shares of the surviving corporation into which the shares of such
dissenting shareholders would have been converted had they assented to the
merger shall have the status of authorized but unissued shares of the surviving
corporation.

                    INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20. Indemnification of Directors and Officers.

         The Registrant's Amended and Restated Certificate of Incorporation
includes a provision limiting the liability of its directors and officers and
its stockholders, to the maximum extent permitted by law, for money damages
except for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit.

         Section 145 of the Delaware General Corporation Law, as amended (the
"DGCL"), provides that under certain circumstances a corporation may indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation or is
or was serving at its request in such capacity in another corporation or
business association, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interest of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such person's
conduct was unlawful.

         The directors and officers of the Registrant are insured under policies
of insurance maintained by the Registrant, subject to the limits of the
policies, against certain losses arising from any claim made against them by
reason of being or having been such directors or officers. In addition, the
Registrant has entered into contracts with all of its directors providing for
indemnification of such persons by the Registrant to the full extent authorized
or permitted by law, subject to certain limited exceptions.

         Schedule II - Valuation and Qualifying Accounts

         All other schedules for which provision is made in the applicable
         accounting regulations promulgated by the Securities and Exchange
         Commission are not required under the related instructions or are
         inapplicable and therefore have been omitted.

Item 22.  Undertakings

         (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

         (2) The registrant undertakes that every prospectus (a) that is filed
pursuant to paragraph (1) immediately preceding, or (b) that purports to meet
the requirements of section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         (3) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

         (4) The undersigned registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     SEC File No. 333-23651
     ----------------------

Ladies and Gentlemen:

     We have acted as counsel to Airgas, Inc. (the "Company"), a Delaware
corporation, in connection with the preparation and filing of a registration
statement on Form S-4, which was filed with the Securities and Exchange
Commission on March 20, 1997 and amended on the date hereof (the "Registration
Statement").  Capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Registration Statement.

     The Registration Statement relates to the issuance of up to 2,411,766
shares of the Company's Common Stock, par value $.01 per share (the "Shares"),
in connection with the proposed merger of Carbonic Industries Corporation into a
wholly-owned subsidiary of the Company, with the Company's subsidiary surviving
the merger.

     We have examined the Registration Statement, including the exhibits
thereto, the Company's Amended and Restated Certificate of Incorporation, the
Company's By-Laws, as amended, the minutes of actions taken by the Board of
Directors of the Company and such other instruments as we deemed necessary for
the opinions rendered herein.  In the foregoing examination, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals and the authenticity of all documents submitted to us as
copies of originals.

- --------------------------------------------------------------------------------

     Based upon the foregoing, we are of the opinion that the Shares, when
issued in the manner contemplated by the Registration Statement, will be validly
issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement and the form of opinion set forth in Exhibit B to the
Merger Agreement filed as Appendix A to the Proxy Statement/Prospectus, which
forms a part of this Registration Statement.  We also consent to the reference
to this firm under the headings "Legal Opinions" and "The Merger -- Certain
Federal Income Tax Consequences of the Merger"  in the Proxy
Statement/Prospectus constituting a part of the Registration Statement.  In
giving this consent, we do not hereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended, or the rules and regulations thereunder.

                                       Sincerely,

                                       McCAUSLAND, KEEN & BUCKMAN
