                DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

    This offering circular contains statements that are forward looking within
the meaning of the Private Securities Litigation Reform Act of 1995. These
statements include, but are not limited to, statements regarding: our strategy
of leveraging our distribution network to sign new strategic accounts, pursue
cross-selling opportunities and promote strategic products; the success of
sales initiatives, including strategic products and accounts, in continuing
sales growth; the effect of price increases on sales growth; our expectation
that continued sales growth and the impact of price increases will help to
offset increases in product costs and operating expenses; the ability of our
cost reduction plan to offset higher operating expenses; our expectation that
we will realize cost savings in fiscal 2002 as a result of our cost reduction
plan; the ability of lower costs from centralized purchasing initiatives and
growth of higher margin private label products to offset lower gross profits
from sales of hardgoods; the estimate of future legal expenses related to the
Praxair, Inc. ("Praxair") lawsuit; the ultimate outcome of the Praxair lawsuit;
the timing, scope, success and effect on diluted earnings per share of the
project designed to improve certain operational and administrative processes;
the funding of future acquisitions, capital expenditures and current debt
maturities through the use of cash flow from operations, revolving credit
facilities, potential sales of assets and other financing alternatives; the
identification of acquisition candidates; future sources of financing and the
refinancing of our credit facilities and other debt instruments over the next
twelve months; the effect on us of higher interest rates; and performance of
counterparties under interest rate swap agreements. These forward-looking
statements involve risks and uncertainties.

    Factors that could cause actual results to differ materially from those
predicted in any forward-looking statement include, but are not limited to:
underlying market conditions; growth and continued improvement in same-store
sales; the success of marketing initiatives on sales of strategic products and
accounts; our inability to control operating expenses and the potential impact
of higher operating expenses in future periods; the market acceptance and
success of private label products; our inability to improve margins through
sales of strategic and private label products; the inability of cost reduction
plans to improve operating margins and mitigate rising product costs and
operating expenses; adverse changes in customer buying patterns; market
acceptance of price increases; the inability of price increases and sales
growth to offset any increases in operating expenses; the impact of higher than
anticipated consulting expenses on future results; an economic downturn
(including adverse changes in the specific markets for our products); the
inability of centralized purchasing and distribution initiatives in lowering
product costs; the inability to generate sufficient cash flow from operations
or other sources to fund future acquisitions, capital expenditures and current
debt maturities; the inability to identify and successfully integrate
acquisition candidates; the inability to obtain financing at favorable rates;
the ability to manage interest rate exposure; the effects of competition from
independent distributors and vertically integrated gas producers on products,
pricing and sales growth; changes in product prices from gas producers and
name-brand manufacturers and suppliers of hardgoods; higher than estimated
legal fees related to the Praxair lawsuit; an unfavorable outcome of the
Praxair lawsuit; uncertainties regarding accidents or litigation which may
arise in the ordinary course of business; and the effects of, and changes in,
the economy, monetary and fiscal policies, laws and regulations, inflation and
monetary fluctuations and fluctuations in interest rates, both on a national
and international basis. We do not undertake to update any forward-looking
statement made herein or that may be made from time to time by or on our
behalf.

                                  Our Business

Overview

    We are the largest distributor of industrial, medical and specialty gases
(delivered in cylinder or "packaged" form) and related welding supplies and
equipment, and the third largest distributor of safety products in the U.S. We
are also a leading producer and distributor of dry ice, liquid carbon dioxide
and nitrous oxide in the U.S. Our products are used in many industries,
including fabricated metal products, agriculture and mining, construction,
medical and health services and food and beverage.

    Our revenue derives principally from the sale of packaged gases, such as
nitrogen, oxygen, argon, helium, acetylene, carbon dioxide, nitrous oxide,
hydrogen and specialty gases; the rental of our gas cylinders, bulk storage
tanks and welding equipment; and the sale of hardgoods, such as welding
supplies and equipment, safety products and maintenance, repair and operations
products. Our total net sales and Adjusted EBITDA for the fiscal year ended
March 31, 2001 were approximately $1.6 billion and $208 million, respectively.

    We estimate the domestic market for packaged gas and welding equipment
sales in 2000 to have been approximately $8 billion. As of the fiscal year
ended March 31, 2001, we believe we had a market share of approximately 15%. We
also have a diversified base of over 700,000 customers, with our largest
customer representing approximately 1% of total net sales.

    We operate the largest packaged gas distribution network in the U.S., with
approximately 700 locations in 44 states, consisting of five regional
distribution centers, 130 gas fill plants and testing facilities, approximately
600 branch stores and four customer call centers. We also operate two air
separation plants, 15 acetylene, 17 dry ice and eight liquid carbon dioxide
production facilities and six specialty gas laboratories.

     the third largest distributor of safety products in the U.S., and a
     leading producer and distributor of dry ice, liquid carbon dioxide and
     nitrous oxide in the U.S.

  .  National distribution footprint. We believe we are better positioned
     than our competitors to serve our customers with superior local service
     and a national scope, with approximately 700 locations in 44 states. We
     believe that our customers find it convenient to do business with us
     through our multiple distribution channels, including our national
     footprint of retail locations, catalogs, telemarketing and eBusiness. It
     would be difficult and expensive for a competitor to replicate the
     national footprint we have assembled through more than 300 acquisitions
     over the last 18 years.

  .  Broad product and service offerings. We offer our customers a broad line
     of products and services, from gases to hardgoods and safety products.
     We have increasingly become a one-stop shopping source for our local and
     national customers, with our broad selection and complementary sets of
     products and services, including the Radnor(TM) private-label products.
     One-stop shopping has also contributed to the success of our national
     strategic accounts program through which we sign multi-year contracts to
     distribute our products to customers with multiple locations across
     broad geographic regions.

  .  Diverse customer base. We believe that our diverse customer base
     minimizes the impact of economic cyclicality. We have over 700,000
     customers representing more than 33 industries, including noncyclical
     businesses such as medical services and food and beverage. In addition,
     we do not rely on any single industry or customer for our sales. Our
     largest industry served and largest individual customer accounted for
     approximately 15% and 1% of our fiscal 2001 total net sales,
     respectively.

  .  Stable cash flows. As a result of our diverse customer base and business
     mix, we have enjoyed stable operating cash flows. In addition, our
     business requires relatively low levels of maintenance capital
     expenditures, and we have already completed most of the capital
     investments required in developing our five regional distribution
     centers. Our available cash flows have enabled us to reduce our
     indebtedness from time to time.

  .  Strong management team with extensive industry experience. Our Chief
     Executive Officer and Chief Operating Officer have an average of 22
     years of experience in the industrial gas and chemicals industries. Our
     senior management team combines professionals with long-term experience
     within our company and recent key hires who bring broad talents and
     expertise from the industrial gas and other industries. Moreover, our
     senior management team is supported by numerous senior managers who have
     extensive experience in our industry and in their respective regions.

Our Strategy

    The key elements of our strategy are:

  .  Focus on internal growth supplemented by acquisitions in our core
     businesses. One of our key objectives is to be the market leader with
     respect to profitable sales growth. We believe that we can achieve this
     goal by leveraging our leading market position, our national
     distribution infrastructure, our multi-channel distribution network and
     our broad product and service offerings. By implementing this strategy,
     we increased same-store sales growth in fiscal 2001 by 3.1% during a
     period of declining non-technology industrial production in the U.S. For
     an explanation of same-store sales, see "Same-store Sales Growth"
     included in our Current Report on Form 8-K dated July 11, 2001.

                                       2



     In addition, to supplement internal growth, we will continue to pursue
     strategic acquisitions of complementary businesses. We are continuously
     evaluating acquisition opportunities and consolidation possibilities,
     and we are currently in various stages of due diligence or preliminary
     discussions with respect to a number of potential transactions, one of
     which would be significant. None of these potential transactions is
     subject to a letter of intent (except for one immaterial acquisition
     that is currently being evaluated) or otherwise so far advanced as to
     make the transaction reasonably certain.

  .  Improve operating efficiencies to become the lowest-cost supplier in the
     industry. We are highly focused on continuously improving our operating
     efficiencies. Our efforts include improving internal logistics and
     supply chain management, standardizing and centralizing administrative
     and financial processes, consolidating our purchasing activities,
     improving utilization of our gas cylinders and implementing
     organization-wide best practices. In the fourth quarter of fiscal 2001,
     we launched a program, which we refer to as Project One, that we believe
     will assist us in achieving these objectives. Project One is expected to
     realize short-term improvements from value-enhancing programs and build
     our long-term scalable infrastructure that will sustain short-term
     improvements and support future growth.

  .  Balance growth with continued discipline in paying down debt and
     improving our credit profile. In fiscal 2001, we reduced our total debt
     by $113 million, in addition to $73.2 million of debt repaid from the
     proceeds of our accounts receivable securitization facility. We expect
     to continue reducing debt and improving our credit ratios by improving
     free cash flow through sales growth, implementing initiatives that we
     expect will result in cost savings and working capital improvements and
     divesting non-core businesses.

                              Recent Developments

    In April 2001, we closed the second and final tranche of our $150 million
accounts receivable securitization facility, which resulted in net proceeds of
$64.3 million, which was subsequently reduced to $64.1 million to reflect
certain changes in our accounts receivable. These net proceeds were applied to
repay outstanding loans under our existing bank credit facilities.

    On July 30, 2001, we obtained a new bank credit facility from a group of
financial institutions for which Bank of America, N.A. is the U.S. agent. The
new bank credit facility consists of a revolving credit facility providing
$367.5 million of dollar-denominated loans and CDN$50 million of Canadian
dollar-denominated loans, including letters of credit. The new bank credit
facility is guaranteed by certain of our domestic subsidiaries and our
borrowings in Canadian dollars are also guaranteed by certain of our Canadian
subsidiaries. See "New Bank Credit Facility" included in our Current Report on
Form 8-K dated July 11, 2001.

    For the quarter ended June 30, 2001, we had sales and net earnings of $416
million and $13.5 million, respectively. Total same-store sales for the quarter
increased 2% as compared to the corresponding quarter a year ago. Same-store
sales for the Distribution segment increased 1%, reflecting an increase of 9%
for gases and rent and a decrease of 5% in hardgoods, while same-store sales
for the Gas Operations segment increased 13%.

                                  The Offering

                     Summary of Terms of the Exchange Offer

                                 
 Background........................  On July 30, 2001, we completed a private
                                     placement of the old notes. In connection
                                     with that private placement, we entered
                                     into a registration rights agreement in
                                     which we agreed, among other things, to
                                     complete an exchange offer.

 The Exchange Offer................  We are offering to exchange our new notes
                                     which have been registered under the
                                     Securities Act of 1933, as amended (the
                                     "Securities Act") for a like principal
                                     amount of our outstanding, unregistered
                                     old notes. Old notes may only be tendered
                                     in integral multiples of $1,000 principal
                                     amount.

                                     As of the date of this prospectus,
                                     $225,000,000 in aggregate principal amount
                                     of our old notes is outstanding.

 Resale of New Notes...............  We believe that new notes issued pursuant
                                     to the exchange offer in exchange for old
                                     notes may be offered for resale, resold
                                     and otherwise transferred by you without
                                     compliance with the registration and
                                     prospectus delivery provisions of the
                                     Securities Act, provided that:

                                     .  you are acquiring the new notes in the
                                        ordinary course of your business;

                                     .  you have not engaged in, do not intend
                                        to engage in, and have no arrangement
                                        or understanding with any person to
                                        participate in the distribution of the
                                        new notes; and

                                     receives new notes for its own account
                                     pursuant to the exchange offer in exchange
                                     for old notes that were acquired as a
                                     result of market-making or other trading
                                     activity must acknowledge that it will
                                     deliver a prospectus in connection with
                                     any resale of new notes. See "Plan of
                                     Distribution."

 Consequences If You Do Not
  Exchange Your Old Notes..........  Old notes that are not tendered in the
                                     exchange offer or are not accepted for
                                     exchange will continue to bear legends
                                     restricting their transfer. You will not
                                     be able to offer or sell the old notes
                                     unless:

                                     .  the sale is exempt from the
                                        registration requirements of the
                                        Securities Act; or

                                     .  the old notes are registered under the

                                     limited exceptions. See "Risk Factors--If

                                     will continue to be restricted and may
                                     become less liquid."

 Expiration Date...................  12:00 (midnight), New York City time, on
                                             , 2001, unless we extend the

                                     of registered ownership may take a
                                     considerable time.

             Summary Description of the Securities to be Registered

Issuer......................  Airgas, Inc., a Delaware corporation.

Notes Offered...............  $225.0 million aggregate principal amount of
                              9.125% Senior Subordinated Notes due 2011.

Maturity Date...............  October 1, 2011.

Interest Payment Dates......  April 1 and October 1 beginning April 1, 2002.

Guarantors..................  The notes will be guaranteed by each of our
                              current and future domestic restricted
                              subsidiaries that guarantee our obligations under
                              the new credit facility. If we cannot make
                              payments on the notes when they are due, the
                              guarantors must make them instead. Not all of our
                              subsidiaries will guarantee the notes.

Ranking.....................  The notes and the subsidiary guarantees are
                              senior subordinated debt. They rank behind all of
                              our and our guarantors' current and future
                              indebtedness, other than trade payables, except
                              indebtedness that expressly provides that it is
                              not senior to the notes and the subsidiary
                              guarantees. The notes rank equally with all of
                              our and our guarantors' future senior
                              subordinated indebtedness. The notes will be
                              effectively subordinated to all debt of
                              subsidiaries that do not guarantee the notes.

Optional Redemption.........  We may redeem the notes, in whole or in part, at
                              any time beginning on October 1, 2006 at the
                              redemption prices listed under "Description of
                              Notes--Optional Redemption."

                              Before October 1, 2006, we may redeem the notes,
                              in whole or in part, at a price equal to 100% of
                              their principal amount plus the make-whole
                              premium described under "Description of Notes--
                              Optional Redemption."

                              In addition, before October 1, 2004, we may
                              redeem up to 35% of the notes issued under the
                              indenture with the proceeds of one or more equity
                              offerings by us at the price listed under
                              "Description of Notes--Optional Redemption."

Offer to Repurchase ........  If we sell assets under some circumstances, or
                              experience specific kinds of changes of control,
                              we must offer to repurchase the notes at the
                              prices listed under "Description of Notes--
                              Repurchase at the Option of Holders."

Basic Covenants.............  The indenture governing the notes contains
                              covenants that, among other things, limit our

                   Summary Consolidated Financial Information

    The following tables present summary financial information for fiscal 1999,
2000 and 2001 and at March 31, 1999, 2000 and 2001. These tables should be read
in conjunction with the information set forth under "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and our
consolidated financial statements and accompanying notes included in our Annual
Report on Form 10-K for fiscal year ended March 31, 2001.

    The information below designated "as adjusted" gives effect to (1) our
accounts receivable securitization facility, the final phase of which was
completed in April 2001, and the repayment of loans under our old bank credit
facilities with the net proceeds, (2) the initial borrowings under the new bank
credit facility and the repayment of loans under our old bank credit facilities
with the net proceeds and (3) the issuance and sale of the old notes and the
application of the net proceeds therefrom to repay loans under our old bank
credit facilities, which events we refer to herein collectively as the
"Refinancing Transactions." The "as adjusted" information is derived from data
contained in our historical financial statements which has been adjusted to
give pro forma effect to the Refinancing Transactions as if the Refinancing
Transactions had occurred as of April 1, 2000 in the case of the income
statement information or March 31, 2001 in the case of the balance sheet
information.

  (b)  divestiture gains of $25.5 million ($15 million after-tax), and
  (c)  a $1.8 million after-tax nonrecurring gain relating to insurance
       proceeds recorded by an equity affiliate.

(2) The results for fiscal 2000 include:
  (a) special charge recoveries of $2.8 million ($1.7 million after-tax),
  (b) divestiture gains of $17.5 million ($8.6 million after-tax),
  (c) a litigation charge of $7.5 million ($4.8 million after-tax),
  (d) an inventory write-down of $3.8 million ($2.2 million after-tax), and
  (e) an after-tax charge of $590,000 representing a change in accounting

  (b) litigation charges, net of $5.3 million ($3.4 million after-tax), and
  (c) asset impairments associated with two equity affiliates of $700,000
      after-tax.

(4) EBITDA represents total operating income plus depreciation, amortization
    and cash dividends and fees from unconsolidated affiliates.

    EBITDA is not a measure of operating income, operating performance or
    liquidity under generally accepted accounting principles ("GAAP"). We
    include EBITDA data because we understand such data are used by certain
    investors to determine our historical ability to service our debt.
    Nevertheless, this measure should not be considered in isolation or as a
    substitute for operating income, as determined in accordance with GAAP, or
    as a measure of liquidity. Additionally, it should be noted that companies
    calculate EBITDA differently and therefore EBITDA as presented for Airgas
    may not be comparable to EBITDA reported by other companies. EBITDA may not
    be indicative of historical operating results, and we do not mean it to be
    indicative of future results of operations or cash flows. You should also
    see the statements of cash flows contained within our consolidated
    financial statements, which are included in our Annual Report on Form 10-K
    for the fiscal year ended March 31, 2001.

(5) Adjusted EBITDA represents EBITDA plus one-time losses and special charges
    minus one-time gains and special recoveries. Adjusted EBITDA was calculated
    as follows:

(7) Earnings consist of pre-tax income from continuing operations before equity
    method earnings or losses plus fixed charges minus minority interest in
    pre-tax income of entities that have not incurred fixed charges. Fixed
    charges consist of interest expense on debt and amortization of deferred
    debt issuance costs, and the portion of rental expense that we believe is
    representative of the interest component of rental expense of approximately
    $11.8 million, $12.8 million and $14.6 million in 1999, 2000 and 2001,
    respectively.

(8) In April 2001, we closed the final tranche of our $150 million accounts
    receivable securitization facility and used the net proceeds of $64.3
    million to repay borrowings under our existing bank credit facilities.
    Currently, there is $137.3 million funded under the facility.

(9) The following table sets forth a reconciliation of interest expense, which
    includes gross interest expense and the discount on the securitization of
    trade receivables of $61.4 million and $1.3 million, respectively, to
    interest expense (as adjusted):

                                  RISK FACTORS

    In addition to the other information in this document, you should consider
the following factors in evaluating Airgas before purchasing the notes.

Risks Relating to Investment in the Notes

If you fail to exchange your old notes, they will continue to be restricted and
may become less liquid.

    Old notes which you do not tender or we do not accept will, following the
exchange offer, continue to be restricted securities, and you may not offer to
sell them except pursuant to an exemption from, or in a transaction not subject
to, the Securities Act and applicable state securities law. We will issue new
notes in exchange for the old notes pursuant to the exchange offer only
following the satisfaction of the procedures and conditions set forth in "The
Exchange Offer--Procedures for Tendering." Such procedures and conditions
include timely receipt by the exchange agent of such old notes and of a
properly completed and duly executed letter of transmittal.

    Because we anticipate that most holders of old notes will elect to exchange
such old notes, we expect that the liquidity of the market for any old notes
remaining after the completion of the exchange offer may be substantially
limited. Any old notes tendered and exchanged in the exchange offer will reduce
the aggregate principal amount at maturity of the old notes outstanding.
Following the exchange offer, if you did not tender your old notes you
generally will not have any further registration rights, and such old notes
will continue to be subject to certain transfer restrictions. Accordingly, the
liquidity of the market for such old notes could be adversely affected. The old
notes are currently eligible for sale pursuant to Rule 144A and Regulation S
under the Securities Act through the Private Offerings, Resale and Trading
through Automated Linkages market of the National Association of Securities
Dealers, Inc.

The notes will be contractually junior in right of payment to all of our senior
indebtedness and the subsidiary guarantees will be contractually junior in
right of payment to all senior indebtedness of the subsidiary guarantors.

    As of March 31, 2001, after giving pro forma effect to the Refinancing
Transactions, we would have had approximately $414.1 million of senior
indebtedness, including letters of credit issued under the new credit facility
aggregating approximately $51.7 million, and our guarantors would have had
approximately $389.2 million of senior indebtedness, including guarantees of
senior debt of Airgas aggregating approximately $360.6 million. Although the
indenture with respect to the notes will contain limitations on our ability to
incur additional indebtedness, those limitations are subject to a number of
qualifications and exceptions that, depending on the circumstances at the time,
would allow us to incur a substantial amount of additional indebtedness, all of
which could be senior indebtedness.

    We generally may not pay our obligations on the notes, or repurchase,
redeem or otherwise retire the notes if any senior indebtedness is not paid
when due or any default on senior indebtedness occurs and the maturity of the
senior indebtedness is accelerated in accordance with its terms, unless, in
either case, the default has been cured or waived, any acceleration has been
rescinded or the senior indebtedness has been repaid in full. In addition, if
certain other defaults regarding our senior indebtedness occur, we may not be
permitted to pay any obligations under the notes or any subsidiary guarantees
for a designated period of time. If we or any subsidiary guarantors are
declared bankrupt or insolvent, or if there is a payment default under, or an
acceleration of, any senior indebtedness, we are required to pay the lenders
under the new bank credit facility and any other creditors who are holders of
senior indebtedness in full before we apply

                                       11


any of our assets to pay you. Accordingly, we may not have enough assets
remaining after payments to holders of the senior indebtedness to pay you.
Also, if our credit ratings are reduced, loans under the new bank credit
facility will become secured by liens on substantially all of our tangible and
intangible assets. The notes are unsecured and therefore do not have the
benefit of any collateral. If any event of default occurs under the new bank
credit facility when the lenders thereunder are secured by those assets, the
lenders may foreclose upon their collateral. In that case, those assets would
first be used to repay in full all amounts outstanding under the new bank
credit facility and may not be available to repay our obligations on the notes.
See "New Bank Credit Facility" included in our Current Report on Form 8-K dated
July 11, 2001 and "Description of the Notes--Events of Default and Remedies"
included in this prospectus.

We may not have sufficient funds to purchase notes upon a change of control.

    If there is a change of control under the terms of the indenture governing
the notes, each holder of notes may require us to purchase all or a portion of
its notes at a purchase price equal to 101% of the principal amount thereof,
plus accrued interest to the date of purchase. Our ability to purchase the
notes upon a change of control may be limited by the terms of our other debt
agreements at that time. In order to purchase any outstanding notes, we might
have to refinance our outstanding indebtedness, which we might not be able to
do. Even if we were able to refinance our other indebtedness, any financing
might be on terms unfavorable to us. In addition, the new bank credit facility
will prohibit us from purchasing any notes, including as a result of any offer
in connection with a change of control, and also provides that the occurrence
of certain kinds of change of control events will constitute a default under
the new bank credit facility. In the event of a certain kind of change of
control, we must offer to repay all borrowings under the new bank credit
facility and obtain the consent of our lenders under the new bank credit
facility to purchase the notes. If we do not obtain such a consent or repay
such borrowings, we will remain prohibited from purchasing notes. In such a
case, our failure to purchase tendered notes would constitute a default under
the indenture governing the notes, which would constitute a default under the
new bank credit facility. We cannot assure you that we will have the financial
ability to purchase outstanding notes upon the occurrence of a change of
control. See "Description of Notes--Change of Control."

Not all of our subsidiaries guarantee our obligations under the notes, and the
assets of the non-guarantor subsidiaries may not be available to make payments
on the notes.

    Our present and future foreign subsidiaries and domestic unrestricted
subsidiaries will not be guarantors of the notes. Payments on the notes are
only required to be made by the subsidiary guarantors and us. As a result, no
payments are required to be made from the assets of subsidiaries that do not
guarantee the notes, unless those assets are transferred by dividend or
otherwise to us or a subsidiary guarantor. See "Description of Notes--
Subordination--Liabilities of Subsidiaries versus Notes." Our non-guarantor
subsidiaries generated 1.3% of our total net sales and 4.6% of our EBITDA in
fiscal 2001.

    In the event of a bankruptcy, liquidation or reorganization of any of the
non-guarantor subsidiaries, holders of their indebtedness, including their
trade creditors and other obligations, including any preferred stock, will be
entitled to payment of their claims from the assets of those subsidiaries
before any assets are made available for distribution to us. As a result, the
notes are effectively subordinated to all the liabilities of the non-guarantor
subsidiaries.

U.S. bankruptcy or fraudulent conveyance law may interfere with the payment of
the subsidiary guarantees.

    Our subsidiaries will not receive any of the proceeds from the notes. Under
U.S. federal bankruptcy law and comparable provisions of state fraudulent
transfer laws, a guarantee could be

                                       12


subordinated to all other indebtedness of that subsidiary guarantor if, among
other things, the subsidiary guarantor, at the time it incurred the
indebtedness evidenced by its guarantee:

  .  incurred the guarantee with the intent of hindering, delaying or
     defrauding current or future creditors; or

  .  received less than reasonably equivalent value or fair consideration
     for incurring the guarantee; and

     .  were insolvent or were rendered insolvent by reason of the
        incurrence;

     .  were engaged, or about to engage, in a business or transaction for
        which the assets remaining with it constituted unreasonably small
        capital to carry on our business;

     .  intended to incur, or believed that it would incur, debts beyond
        its ability to pay as these debts matured; or

     .  were a defendant in an action for money damages, or had a judgment
        for money damages entered against us if, in either case, after
        final judgment the judgment was unsatisfied.

    The measure of insolvency for these purposes will vary depending upon the
law of the jurisdiction that is being applied in any proceeding. Generally,
however, a debtor would be considered insolvent if, at the time the debtor
incurred the indebtedness, either:

  .  the sum of the debtor's debts and liabilities, including contingent
     liabilities, is greater than the debtor's assets at fair valuation; or

  .  the present fair saleable value of the debtor's assets is less than the
     amount required to pay the probable liability on the debtor's total
     existing debts and liabilities, including contingent liabilities, as
     they become absolute and matured.

    If the subsidiary guarantees are not enforceable, the notes would be
effectively junior in ranking to all liabilities of the subsidiary guarantors,
including trade payables of the subsidiary guarantors, and to any other prior
claims, including claims by holders of any preferred stock. In addition, any
payment by such subsidiary guarantor pursuant to its guarantee could be voided
and required to be returned to such guarantor, or to a fund for the benefit of
the creditors of the subsidiary guarantor. As of March 31, 2001, on a pro forma
basis, after giving effect to the Refinancing Transactions our subsidiary
guarantors had total liabilities, excluding liabilities owed to us and
guarantees of our indebtedness, of approximately $373.4 million.

Investors may find it difficult to trade the new notes.

    The new notes are a new issue of securities, and there is currently no
public market for the new notes. We do not intend to apply for listing of the
new notes on any securities exchange. We also cannot assure you that you will
be able to sell your new notes at a particular time or that the prices that you
receive when you sell will be favorable. We also cannot assure you as to the
level of liquidity of the trading market for the new notes. Future trading
prices of the new notes will depend on many factors, including:

  .  our operating performance, prospects and financial condition or the
     operating performance, prospects and financial condition of companies
     in our industry generally;

  .  the interest of securities dealers in making a market for the new
     notes; and

  .  the market for similar securities.

Historically, the market for non-investment-grade debt has been subject to
disruptions that have caused volatility in prices. It is possible that the
market for the new notes will be subject to

                                       13


disruptions. Any disruptions may have a negative effect on the holders of the
new notes, regardless of our prospects and financial performance.

Risks Relating to Our Business

We have significant debt and our debt service obligations are substantial.

    We have substantial amounts of outstanding indebtedness. As of March 31,
2001, after giving pro forma effect to the Refinancing Transactions, we would
have had total consolidated Adjusted debt of approximately $821 million, which
includes $639.1 million of long-term debt, $44.2 million of synthetic lease
obligations and $137.3 million of our accounts receivable securitization
facility. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" included in our Annual Report on Form 10-K for fiscal
year ended March 31, 2001.

    Our substantial indebtedness could have significant negative consequences,
including:

  .  increasing our vulnerability to general adverse economic and industry
     conditions;

  .  limiting our ability to obtain additional financing for working
     capital, capital expenditures, acquisitions and other purposes;

  .  requiring the dedication of a significant portion of our expected cash
     flow from operations to service our indebtedness, thereby reducing the
     amount of our expected cash flow available for working capital, capital
     expenditures, acquisitions and other purposes;

  .  making it more difficult to satisfy our obligations with respect to the
     notes;

  .  limiting our flexibility in planning for, or reacting to, changes in
     our business and industry;

  .  placing us at a possible competitive disadvantage relative to less
     leveraged competitors;

  .  increasing the amount of our interest expense, because some of our
     borrowings are at variable rates of interest, which, if interest rates
     increase, could result in higher interest expense; and

  .  limiting, through the financial and other restrictive covenants in our
     indebtedness, among other things, our ability to borrow additional
     funds, dispose of assets or make investments.

    After giving pro forma effect to the Refinancing Transactions, our pro
forma interest expense for fiscal 2001 would have been $71.0 million. This pro
forma interest expense does not take into account the costs of our synthetic
leases. Our ability to meet our expenses and debt obligations will depend on
our future performance, which will be affected by financial, business, economic
and other factors. We will not be able to control many of these factors, such
as economic conditions, governmental regulation and the availability of fuel
supplies. We cannot be certain that our earnings will be sufficient to allow us
to pay the principal and interest on our debt, including the notes, and meet
our other obligations. If we do not have enough money, we may be required to
refinance all or part of our existing debt, including the notes, sell assets,
borrow more money or sell equity. We cannot assure you that we will be able to
accomplish any of these alternatives on terms acceptable to us, if at all.

Despite currently expected levels of indebtedness, our subsidiaries and we will
be able to incur substantially more debt.

    Our subsidiaries and we will be able to incur substantial additional
indebtedness in the future. Although the new bank credit facility and the
indenture governing the notes contain limitations on the incurrence of
additional indebtedness, those limitations are subject to a number of
qualifications and exceptions that, depending on the circumstances at the time,
would allow us to incur a substantial

                                       14


amount of additional indebtedness. As of March 31, 2001, after giving pro forma
effect to the Refinancing Transactions, we would have had availability under
our new bank credit facility of approximately $105 million as a result of
limitations imposed by its financial covenants. In addition, the indenture with
respect to the notes does not restrict us from incurring obligations that do
not constitute indebtedness or preferred stock (as those terms are used in the
indenture). To the extent new debt and other obligations are added to our and
our subsidiaries' currently anticipated debt levels, the substantial risks
described above would increase.

Many of our customers are in cyclical industries some of which are currently
experiencing downturns.

    Demand for our products is affected by general economic conditions. A
decline in general economic or business conditions in the industries served by
our customers can have a material adverse effect on our business. In addition,
many of our customers are in businesses that are cyclical in nature, such as
the automotive and oil and gas industries. Downturns in these industries, even
during periods of strong general economic conditions, can adversely affect our
sales and our financial results.

We may not be successful in generating internal sales growth and in controlling
expenses.

    Although one of our principal business strategies is to improve our
internal sales growth, the achievement of this objective may be adversely
affected by:

  .  competition from independent distributors and vertically integrated gas
     producers on products and pricing;

  .  changes in supply prices from gas producers and manufacturers of
     hardgoods; and

  .  general economic conditions in the industrial markets which we serve,
     including metal fabrication, agriculture, mining, construction and
     other markets.

In addition, we may not be able to adequately control expenses due to inflation
and potentially higher costs of our distribution infrastructure, including the
cost of developing new sales channels, such as eBusiness.

Increases in energy costs could reduce our profitability.

    The cost of industrial gases represented a significant percentage of our
operating costs in fiscal 2001. Because the production of industrial gases
requires significant amounts of electric energy, industrial gas prices have
historically increased as the cost of electric energy increases. Recent
shortages of energy in various states may cause energy prices to continue to
rise and, as a result, increase the cost of industrial gases. In addition, a
significant portion of our distribution costs is comprised of diesel fuel
costs, which have been rising recently. While we have historically been able to
pass increases in the cost of our supplies on to our customers, we cannot
assure you that we will be able to continue to do so in the future. Increases
in energy and other costs that we are unable to pass on to our customers could
significantly reduce our profitability.

We may not be successful in making acquisitions.

    We have historically expanded our business primarily through acquisitions.
A part of our business strategy is to continue to grow through the acquisition
of producers and distributors of industrial gases and related equipment. We are
continuously evaluating acquisition opportunities and consolidation
possibilities, and we are currently in various stages of due diligence or
preliminary discussions with respect to a number of potential transactions, one
of which would be significant.

                                       15


None of these potential transactions is subject to a letter of intent (except
for one immaterial acquisition that is currently being evaluated) or otherwise
so far advanced as to make the transaction reasonably certain. We cannot assure
you that we will continue to be able to identify acquisition candidates, or
that we will be able to make acquisitions on terms acceptable to us. In
addition, there is no assurance that we will be able to obtain financing on
terms acceptable to us for future acquisitions and, in any event, such
financing may be restricted by the terms of our new bank credit facility or the
indenture relating to the notes.

We may not be successful in integrating our past and future acquisitions and
achieving intended benefits and synergies.

    The process of integrating acquired operations into our operations and
achieving targeted synergies may result in unexpected operating difficulties
and may require significant financial and other resources that would otherwise
be available for the ongoing development or expansion of the existing
operations. Acquisitions involve numerous risks, including:

  .  difficulty with the assimilation of acquired operations and products;

  .  failure to achieve targeted synergies;

  .  inability to retain key employees and business relationships of acquired
     companies; and

  .  diversion of the attention and resources of our management team.

Acquisitions may have a material adverse effect on our business.

    We may be required to incur additional debt in order to consummate
acquisitions in the future, which debt may be substantial. In addition,
acquisitions may result in the assumption of the outstanding indebtedness of
the acquired company, as well as the incurrence of contingent liabilities and
other expenses. All of the foregoing could materially adversely affect our
financial condition and operating results.

We cannot assure you that we will be able to successfully implement Project
One, our strategic initiative, or that this initiative will produce its
anticipated positive effects.

    In the fourth quarter of fiscal 2001, we launched a program, which we refer
to as Project One, that we believe will assist us in achieving our strategic
objectives. Project One is expected to realize short-term improvements from
value-enhancing programs and build our long-term scalable infrastructure, which
will sustain our profitable growth, both organic growth and growth through
future acquisitions. During the implementation phase of Project One, we expect
our implementation costs to exceed realized savings. Moreover, we cannot assure
you that we will be able to successfully implement Project One as currently
contemplated, or at all, or that the anticipated cost savings will be realized
as a result of the implementation.

We depend on our key personnel to manage our business effectively and they may
be difficult to replace.

    Our performance substantially depends on the efforts and abilities of our
senior management team, including our Chairman and Chief Executive Officer, and
other executive officers and key employees. Furthermore, much of our
competitive advantage is based on the expertise, experience and know-how of our
key personnel regarding our distribution infrastructure, systems and products.
The loss of key employees could have a negative effect on our business,
revenues, results of operations and financial condition.


                                       16


Litigation may have a material adverse effect on our business.

    From time to time, we are involved in lawsuits that arise from our business
transactions, including the Praxair litigation described under "Business--Legal
Proceedings" included in our Annual Report on Form 10-K for fiscal year ended
March 31, 2001. The defense and ultimate outcome of lawsuits against us may
result in higher operating expenses. Those higher operating expenses could have
a material adverse effect on our business, results of operations or financial
condition.

We will have ongoing environmental costs.

    We are subject to laws and regulations relating to the protection of the
environment and natural resources. These include, among other things, the
management of hazardous substances and wastes, air emissions and water
discharges. Violations of some of these laws can result in substantial
penalties, temporary or permanent plant closures and criminal convictions.
Moreover, the nature of our existing and historical operations exposes us to
the risk of liabilities to third parties. These potential claims include
property damage, personal injuries and cleanup obligations. See "Business--
Regulatory and Environmental Matters" included in our Annual Report on Form 10-
K for fiscal year ended March 31, 2001.

We operate in a highly competitive environment.

    The U.S. industrial gas industry is comprised of a small number of major
producers. Additionally, there are hundreds of smaller, local distributors,
some of whom operate on a low-cost basis, primarily in the cylinder segment.
Some of our competitors may have greater financial resources than we do. If we
are unable to compete effectively with our competitors, we will suffer lower
revenue and a loss of market share.

Although the current trend is for increasing prices, the industrial gas
industry has experienced periods of falling prices, and if such a trend were to
return, we could experience reduced revenues and/or cash flows.

    Previously, our major competitors and we have had to reduce prices in order
to maintain our market share. Although prices are now increasing, in part due
to increased energy and raw materials prices, we cannot assure you that the
prices of our products will not fall in the future, which could adversely
affect our revenues and cash flows, or that we will be able to maintain current
levels of profitability.

                                USE OF PROCEEDS

    We will not receive any proceeds from the exchange offer.

                                       17


                               THE EXCHANGE OFFER

Purpose of the Exchange Offer

    In connection with the sale of the old notes, we entered into a
registration rights agreement with the initial purchasers, under which we
agreed to use our best efforts to file and have declared effective an exchange
offer registration statement under the Securities Act.

    We are making the exchange offer in reliance on the position of the
Commission as set forth in certain no-action letters. However, we have not
sought our own no-action letter. Based upon these interpretations by the
Commission, we believe that a holder of new notes, but not a holder who is our
"affiliate" within the meaning of Rule 405 of the Securities Act, who exchanges
old notes for new notes in the exchange offer, generally may offer the new
notes for resale, sell the new notes and otherwise transfer the new notes
without further registration under the Securities Act and without delivery of a
prospectus that satisfies the requirements of Section 10 of the Securities Act.
This does not apply, however, to a holder who is our "affiliate" within the
meaning of Rule 405 of the Securities Act. We also believe that a holder may
offer, sell or transfer the new notes only if the holder acquires the new notes
in the ordinary course of its business and is not participating, does not
intend to participate and has no arrangement or understanding with any person
to participate in a distribution of the new notes.

    Any holder of the old notes using the exchange offer to participate in a
distribution of new notes cannot rely on the no-action letters referred to
above. This includes a broker-dealer that acquired old notes directly from us,
but not as a result of market-making activities or other trading activities.
Consequently, the holder must comply with the registration and prospectus
delivery requirements of the Securities Act in the absence of an exemption from
such requirements.

    Each broker-dealer that receives new notes for its own account in exchange
for old notes, as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such new notes. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of new notes received in exchange for old notes where such old
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The letter of transmittal states that
by acknowledging and delivering a prospectus, a broker-dealer will not be
considered to admit that it is an "underwriter" within the meaning of the
Securities Act. We have agreed that for a period of 120 days after the
expiration date, we will make this prospectus available to broker-dealers for
use in connection with any such resale. See "Plan of Distribution."

    Except as described above, this prospectus may not be used for an offer to
resell, resale or other transfer of new notes.

    The exchange offer is not being made to, nor will we accept tenders for
exchange from, holders of old notes in any jurisdiction in which the exchange
offer or the acceptance of it would not be in compliance with the securities or
blue sky laws of such jurisdiction.

Terms of the Exchange

    Upon the terms and subject to the conditions of the exchange offer, we will
accept any and all old notes validly tendered prior to 12:00 (midnight), New
York time, on the expiration date. The date of acceptance for exchange of the
old notes, and completion of the exchange offer, is the exchange date, which
will be the first business day following the expiration date (unless extended
as described in this document). We will issue, on or promptly after the
exchange date, an aggregate principal amount of up to $225,000,000 of new notes
for a like principal amount of outstanding old notes

                                       18


tendered and accepted in connection with the exchange offer. The new notes
issued in connection with the exchange offer will be delivered on the earliest
practicable date following the exchange date. Holders may tender some or all of
their old notes in connection with the exchange offer, but only in $1,000
increments of principal amount at maturity.

    The terms of the new notes are identical in all material respects to the
terms of the old notes, except that the new notes have been registered under
the Securities Act and are issued free from any covenant regarding
registration, including the payment of liquidated damages upon a failure to
file or have declared effective an exchange offer registration statement or to
complete the exchange offer by certain dates. The new notes will evidence the
same debt as the old notes and will be issued under the same indenture and
entitled to the same benefits under that indenture as the old notes being
exchanged. As of the date of this prospectus, $225,000,000 in aggregate
principal amount of the old notes is outstanding.

    In connection with the issuance of the old notes, we arranged for the old
notes originally purchased by qualified institutional buyers and those sold in
reliance on Regulation S under the Securities Act to be issued and transferable
in book-entry form through the facilities of The Depository Trust Company
("DTC"), acting as depositary. Except as described under "Description of
Notes--Book-Entry, Delivery and Form," the new notes will be issued in the form
of a global note registered in the name of DTC or its nominee and each
beneficial owner's interest in it will be transferable in book-entry form
through DTC. See "Description of Notes--Book-Entry, Delivery and Form."

    Holders of old notes do not have any appraisal or dissenters' rights in
connection with the exchange offer. Old notes which are not tendered for
exchange or are tendered but not accepted in connection with the exchange offer
will remain outstanding and be entitled to the benefits of the indenture under
which they were issued, but will not be entitled to any registration rights
under the registration rights agreement.

    We shall be considered to have accepted validly tendered old notes if and
when we have given oral or written notice to the exchange agent. The exchange
agent will act as agent for the tendering holders for the purposes of receiving
the new notes from us.

    If any tendered old notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events described in this
prospectus or otherwise, we will return the old notes, without expense, to the
tendering holder as quickly as possible after the expiration date.

    Holders who tender old notes will not be required to pay brokerage
commissions or fees or, subject to the instructions in the letter of
transmittal, transfer taxes on exchange of old notes in connection with the
exchange offer. We will pay all charges and expenses, other than certain
applicable taxes described below, in connection with the exchange offer. See
"--Fees and Expenses."

Expiration Date; Extensions; Amendments

    The expiration date for the exchange offer is 12:00 (midnight), New York
City time, on       , 2001, unless extended by us in our sole discretion (but
in no event to a date later than        , 2001), in which case the term
"expiration date" shall mean the latest date and time to which the exchange
offer is extended.

    We reserve the right, in our sole discretion:

  .  to delay accepting any old notes, to extend the offer or to terminate
     the exchange offer if, in our reasonable judgment, any of the
     conditions described below shall not have been

                                       19


     satisfied, by giving oral or written notice of the delay, extension or
     termination to the exchange agent, or

  .  to amend the terms of the exchange offer in any manner.

    If we amend the exchange offer in a manner that we consider material, we
will disclose such amendment by means of a prospectus supplement, and we will
extend the exchange offer for a period of five to ten business days.

    If we determine to make a public announcement of any delay, extension,
amendment or termination of the exchange offer, we will do so by making a
timely release through an appropriate news agency.

Interest on the New Notes

    Interest on the new notes will accrue at the rate of 9.125% per annum from
the most recent date to which interest on the new notes has been paid or, if no
interest has been paid, from the date of the indenture governing the notes.
Interest will be payable semiannually in arrears on April 1 and October 1,
commencing on April 1, 2002.

Conditions to the Exchange Offer

    Despite any other term of the exchange offer, we will not be required to
accept for exchange, or exchange new notes for, any old notes and may terminate
the exchange offer as provided in this prospectus before the acceptance of the
old notes, if:

  .  any action or proceeding is instituted or threatened in any court or by
     or before any governmental agency relating to the exchange offer which,
     in our reasonable judgment, might materially impair our ability to
     proceed with the exchange offer or materially impair the contemplated
     benefits of the exchange offer to us, or any material adverse
     development has occurred in any existing action or proceeding relating
     to us or any of our subsidiaries;

  .  any change, or any development involving a prospectus change, in our
     business or financial affairs or any of our subsidiaries has occurred
     which, in our reasonable judgment, might materially impair our ability
     to proceed with the exchange offer or materially impair the
     contemplated benefits of the exchange offer to us;

  .  any law, statue, rule or regulation is proposed, adopted or enacted,
     which in our reasonable judgment, might materially impair our ability
     to proceed with the exchange offer or materially impair the
     contemplated benefits of the exchange offer to us; or

  .  any governmental approval has not been obtained, which approval we, in
     our reasonable discretion, consider necessary for the completion of the
     exchange offer as contemplated by this prospectus.

    The conditions listed above are for our sole benefit and may be asserted by
us regardless of the circumstances giving rise to any of these conditions. We
may waive these conditions in our reasonable discretion in whole or in part at
any time and from time to time. The failure by us at any
time to exercise any of the above rights shall not be considered a waiver of
such right, and such right shall be considered an ongoing right which may be
asserted at any time and from time to time.

                                       20


    If we determine in our reasonable discretion that any of the conditions are
not satisfied, we may:

  .  refuse to accept any old notes and return all tendered old notes to the
     tendering holders;

  .  extend the exchange offer and retain all old notes tendered before the
     expiration of the exchange offer, subject, however, to the rights of
     holders to withdraw these old notes (See "--Withdrawal of Tenders"
     below); or

  .  waive unsatisfied conditions relating to the exchange offer and accept
     all properly tendered old notes which have not been withdrawn.

Procedures for Tendering

    Unless the tender is being make in book-entry form, to tender in the
exchange offer, a holder must:

  .  complete, sign and date the letter of transmittal, or a facsimile of
     it,

  .  have the signatures guaranteed if required by the letter of
     transmittal, and

  .  mail or otherwise deliver the letter of transmittal or the facsimile,
     the old notes and any other required documents to the exchange agent
     prior to 12:00 (midnight), New York City time, on the expiration date.

    Any financial institution that is a participant in DTC's Book-Entry
Transfer Facility system may make book-entry delivery of the old notes by
causing DTC to transfer the old notes into the exchange agent's account.
Although delivery of old notes may be effected through book-entry transfer into
the exchange agent's account at DTC, the letter of transmittal (or facsimile),
with any required signature guarantees and any other required documents, must,
in any case, be transmitted to and received or confirmed by the exchange agent
at its addresses set forth under the caption "exchange agent" below, prior to
12:00 (midnight), New York City time, on the expiration date. Delivery of
documents to DTC in accordance with its procedures does not constitute delivery
to the exchange agent.

    The tender by a holder of old notes will constitute an agreement between us
and the holder in accordance with the terms and subject to the conditions set
forth in this prospectus and in the letter of transmittal.

    The method of delivery of old notes and the letter of transmittal and all
other required documents to the exchange agent is at the election and risk of
the holders. Instead of delivery by mail, we recommend that holders use an
overnight or hand delivery service. In all cases, holders should allow
sufficient time to assure delivery to the exchange agent before the expiration
date. No letter of transmittal of old notes should be sent to us. Holders may
request their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the tenders for such holders.

    Any beneficial owner whose old notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on behalf of the beneficial owner. If the
beneficial owner wishes to tender on that owner's own behalf, the owner must,
prior to completing and executing the letter of transmittal and delivery of
such owner's old notes, either make appropriate arrangements to register
ownership of the old notes in the owner's name or obtain a
properly completed bond power from the registered holder. The transfer of
registered ownership may take considerable time.


                                       21


    Signature on a letter of transmittal or a notice of withdrawal must be
guaranteed by an eligible guarantor institution within the meaning of Rule
17Ad-15 under the Exchange Act, unless the old notes tendered pursuant thereto
are tendered:

  .  by a registered holder who has not completed the box entitled "Special
     Payment Instructions" or "Special Delivery Instructions" on the letter
     of transmittal, or

  .  for the account of an eligible guarantor institution.

    In the event that signatures on a letter or transmittal or a notice of
withdrawal are required to be guaranteed, such guarantee must be by:

  .  a member firm of a registered national securities exchange or of the
     National Association of Securities Dealers, Inc.,

  .  a commercial bank or trust company having an office or correspondent in
     the United States, or

  .  an "eligible guarantor institution."

    If the letter of transmittal is signed by a person other than the
registered holder of any old notes, the old notes must be endorsed by the
registered holder or accompanied by a properly completed bond power, in each
case signed or endorsed in blank by the registered holder.

    If the letter of transmittal or any old notes or bond powers are signed or
endorsed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and, unless waived by
us, submit evidence satisfactory to us of their authority to act in that
capacity with the letter of transmittal.

    We will determine all questions as to the validity, form, eligibility
(including time of receipt) and acceptance and withdrawal of tendered old notes
in our sole discretion. We reserve the absolute right to reject any and all old
notes not properly tendered or any old notes whose acceptance by us would, in
the opinion of our U.S. counsel, be unlawful. We also reserve the right to
waive any defects, irregularities or conditions of tender as to any particular
old notes either before or after the expiration date. Our interpretation of the
terms and conditions of the exchange offer (including the instructions in the
letter of transmittal) will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of old notes must be
cured within a time period we will determine. Although we intend to request the
exchange agent to notify holders of defects or irregularities relating to
tenders of old notes, neither we, the exchange agent nor any other person will
have any duty or incur any liability for failure to give such notification.
Tenders of old notes will not be considered to have been made until such
defects or irregularities have been cured or waived. Any old notes received by
the exchange agent that are not properly tendered and as to which the defects
or irregularities have not been cured or waived will be returned by the
exchange agent to the tendering holders, unless otherwise provided in the
letter of transmittal, as soon as practicable following the expiration date.

    In addition, we reserve the right, as set forth above under the caption "--
Conditions to the Exchange Offer," to terminate the exchange offer.

    By tendering, each holder represents to us, among other things, that:

  .  the new notes acquired in connection with the exchange offer are being
     obtained in the ordinary course of business of the person receiving the
     new notes, whether or not such person is the holder;


                                       22


  .  neither the holder nor any such other person has an arrangement or
     understanding with any person to participate in the distribution of
     such new notes; and

  .  neither the holder nor any such other person is our "affiliate" (as
     defined in Rule 405 under the Securities Act).

  .  if the holder is a broker-dealer which will receive new notes for its
     own account in exchange for old notes, it will acknowledge that it
     acquired such old notes as the result of market-making activities or
     other trading activities and it will deliver a prospectus in connection
     with any resale of such new notes. See "Plan of Distribution."

Guaranteed Delivery Procedures

    A holder who wishes to tender its old notes and:

  .  whose old notes are not immediately available;

  .  who cannot deliver the holder's old notes, the letter of transmittal or
     any other required documents to the exchange agent prior to the
     expiration date; or

  .  who cannot complete the procedures for book-entry transfer before the
     expiration date may effect a tender if:

    .  the tender is made through an eligible guarantor institution;

    .  before the expiration date, the exchange agent receives from the
       eligible guarantor institution:

           .  a properly completed and duly executed notice of guaranteed
              delivery by facsimile transmission, mail or hand delivery,

           .  the name and address of the holder,

           .  the certificate number(s) of the old notes and the principal
              amount at maturity of old notes tendered, stating that the
              tender is being made and guaranteeing that, within three New
              York Stock Exchange trading days after the expiration date, the
              letter of transmittal and the certificate(s) representing the
              old notes (or a confirmation of book-entry transfer), and any
              other documents required by the letter of transmittal will be
              deposited by the eligible guarantor institution with the
              exchange agent; and

           .  the exchange agent receives, within three New York Stock
              Exchange trading days after the expiration date, a properly
              completed and executed letter of transmittal or facsimile, as
              well as the certificate(s) representing all tendered old notes
              in proper form for transfer or a confirmation of book-entry
              transfer, and all other documents required by the letter of
              transmittal.

Withdrawal of Tenders

    Except as otherwise provided herein, tenders of old notes may be withdrawn
at any time prior to 12:00 (midnight), New York City time, on the expiration
date.

    To withdraw a tender of old notes in connection with the exchange offer, a
written facsimile transmission notice of withdrawal must be received by the
exchange agent at its address set forth herein prior to 12:00 (midnight), New
York City time, on the expiration date. Any such notice of withdrawal must:

  .  specify the name of the person who deposited the old notes to be
     withdrawn,

  .  identify the old notes to be withdrawn (including the certificate
     number or numbers and principal amount at maturity of such old notes),

                                       23


  .  be signed by the depositor in the same manner as the original signature
     on the letter of transmittal by which such old notes were tendered
     (including any required signature guarantees) or be accompanied by
     documents or transfer sufficient to have the trustee register the
     transfer of such old notes into the name of the person withdrawing the
     tender, and

  .  specify the name in which any such old notes are to be registered, if
     different from that of the depositor.

    We will determine all questions as to the validity, form and eligibility
(including time of receipt) of such withdrawal notices. Any old notes so
withdrawn will be considered not to have been validly tendered for purposes of
the exchange offer, and no new notes will be issued unless the old notes
withdrawn are validly re-tendered. Any old notes which have been tendered but
which are not accepted for exchange or which are withdrawn will be returned to
the holder without cost to such holder as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. Properly withdrawn
old notes may be re-tendered by following one of the procedures described above
under the caption "--Procedures for Tendering" at any time prior to the
expiration date.

Exchange Agent

    The Bank of New York has been appointed as exchange agent in connection
with the exchange offer. Questions and requests for assistance, requests for
additional copies of this prospectus or of the letter of transmittal should be
directed to the exchange agent, at its offices at Corporate Trust Department,
3rd floor, 385 Rifle Camp Road, West Paterson, NJ 07424, Attention: Terence
Rawlins. The exchange agent's telephone number is (973) 357-7055 and facsimile
number is (973) 357-7840.


Fees and Expenses

    We will not make any payment to brokers, dealers or others soliciting
acceptances of the exchange offer. We will pay certain other expenses to be
incurred in connection with the exchange offer, including the fees and expenses
of the exchange agent, accounting and certain legal fees.

    Holders who tender their old notes for exchange will not be obligated to
pay transfer taxes. If, however:

  .  new notes are to be delivered to, or issued in the name of, any person
     other than the registered holder of the old notes tendered, or

  .  if tendered old notes are registered in the name of any person other
     than the person signing the letter of transmittal, or

  .  if a transfer tax is imposed for any reason other than the exchange of
     old notes in connection with the exchange offer,

then the amount of any such transfer taxes (whether imposed on the registered
holder or any other persons) will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or exemption from them is not
submitted with the letter of transmittal, the amount of such transfer taxes
will be billed directly to the tendering holder.

Accounting Treatment

    The new notes will be recorded at the same carrying value as the old notes
as reflected in our accounting records on the date of the exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes
upon the completion of the exchange offer. The expenses of the exchange

                                       24


offer that we pay will increase our deferred financing costs in accordance
with generally accepted accounting principles.

Consequences of Failures to Properly Tender Old Notes in the Exchange

    Issuance of the new notes in exchange for the old notes under the exchange
offer will be made only after timely receipt by the exchange agent of such old
notes, a properly completed and duly executed letter of transmittal and all
other required documents. Therefore, holders of the old notes desiring to
tender such old notes in exchange for new notes should allow sufficient time
to ensure timely delivery. We are under no duty to give notification of
defects or irregularities of tenders of old notes for exchange. Old notes that
are not tendered or that are tendered but not accepted by us will, following
completion of the exchange offer, continue to be subject to the existing
restrictions upon transfer thereof under the Securities Act, and, upon
completion of the exchange offer, certain registered rights under the
registration rights agreement will terminate.

    In the event the exchange offer is completed, we will not be required to
register the remaining old notes. Remaining old notes will continue to be
subject to the following restrictions on transfer:

  .  the remaining old notes may be resold only if registered pursuant to
     the Securities Act, if any exemption from registration is available, or
     if neither such registration nor such exemption is required by law, and

  .  the remaining old notes will bear a legend restricting transfer in the
     absence of registration or an exemption.

    We do not currently anticipate that we will register the remaining old
notes under the Securities Act. To the extent that old notes are tendered and
accepted in connection with the exchange offer, any trading market for
remaining old notes could be adversely affected.

                      RATIO OF EARNINGS TO FIXED CHARGES

    The following table sets forth our ratio of earnings to fixed charges for
the periods indicated:

    For purposes of computing the above ratios: (1) earnings consist of pre-
tax income from continuing operations before equity method earnings or losses
plus fixed charges minus minority interest in pre-tax income of entities that
have not incurred fixed charges; and (2) fixed charges consist of interest
expense on debt and amortization of deferred debt issuance costs, and the
portion of rental expense that we believe is representative of the interest
component of rental expense of approximately $8.0 million, $10.1 million,
$11.8 million, $12.8 million, $14.6 million and $3.6 million in 1997, 1998,
1999, 2000, 2001 and the three months ended June 30, 2001, respectively.

                              DESCRIPTION OF NOTES

    You can find the definitions of certain terms used in this description
under the subheading "Certain Definitions." In this description, "Airgas"
refers only to Airgas, Inc. and not to any of its subsidiaries.

    Airgas issued the old notes under an indenture dated July 30, 2001 among
itself, the Guarantors and The Bank of New York, as trustee. The new notes
(which are sometimes referred to in this description as "exchange notes") will
be issued under the same indenture and will be identical in all material
respects to the old notes, except that the new notes have been registered under
the Securities Act and are free of any obligation regarding registration,
including the payment of liquidated damages upon failure to file or have
declared effective an exchange offer registration statement or to consummate an
exchange offer by certain dates. Unless specifically stated to the contrary,
the following description applies equally to the new notes and the old notes.
The terms of the notes include those stated in the indenture and those made
part of the indenture by reference to the Trust Indenture Act of 1939.

    The following description is a summary of the material provisions of the
indenture and the registration rights agreement. It does not restate those
agreements in their entirety. We urge you to read the indenture and the
registration rights agreement because they, and not this description, define
your rights as holders of the notes. Copies of the indenture and the
registration rights agreement are available as set forth below under "--
Additional Information." Certain defined terms used in this description but not
defined below under "--Certain Definitions" have the meanings assigned to them
in the indenture.

    The registered Holder of a note will be treated as the owner of it for all
purposes. Only registered Holders will have rights under the indenture.

Brief Description of the Notes and the Guarantees

The Notes

    The notes:

  .  are general unsecured senior subordinated obligations of Airgas;

  .  are subordinated in right of payment to all existing and future Senior
     Debt of Airgas, including borrowings under the New Credit Facility;

  .  rank pari passu in right of payment with any future unsecured Senior
     Subordinated Indebtedness of Airgas;

  .  are effectively junior to all existing and future liabilities,
     including trade payables, of Airgas' non-guarantor Subsidiaries;

  .  are guaranteed by the Guarantors; and

  .  are subject to registration with the Commission pursuant to the
     registration rights agreement.

The Guarantees

    The notes are guaranteed on a senior subordinated basis by all of Airgas'
Domestic Restricted Subsidiaries that guarantee our obligations under the New
Credit Facility.

    Each guarantee of the notes:

  .  is a general unsecured senior subordinated obligation of the Guarantor;

                                       26


  .  is subordinated in right of payment to all existing and future Senior
     Debt of that Guarantor; and

  .  ranks pari passu in right of payment with any future unsecured Senior
     Subordinated Indebtedness of that Guarantor.

    After giving pro forma effect to the Refinancing Transactions, as of March
31, 2001, Airgas would have had total Senior Debt of approximately $414.1
million, including letters of credit aggregating approximately $51.7 million
that secure Senior Debt of certain of the Guarantors, and the Guarantors would
have had total Senior Debt of approximately $389.2 million, including
approximately $360.6 million representing guarantees of Senior Debt of Airgas.
As indicated above and as discussed in detail below under the caption "--
Subordination," payments on the notes and under the guarantees of the notes
will be subordinated to the payment in cash of Senior Debt. The indenture will
permit the Guarantors and us to incur additional debt, including Senior Debt,
in the future.

    Not all of our Subsidiaries will guarantee the notes. In the event of a
bankruptcy, liquidation or reorganization of any of these non-guarantor
Subsidiaries, the non-guarantor Subsidiaries will pay the holders of their debt
and their trade creditors before they will be able to distribute any of their
assets to us. The guarantor Subsidiaries generated 98.7% of our total net sales
in fiscal 2001. The non-guarantor Subsidiaries generated approximately 4% of
our EBITDA in fiscal 2001.

    As of the date of the indenture, all of our Domestic Subsidiaries will be
"Restricted Subsidiaries." However, under the circumstances described below
under the subheading "Certain Covenants--Designation of Restricted and
Unrestricted Subsidiaries," we will be permitted to designate certain of our
Subsidiaries as "Unrestricted Subsidiaries." Our Unrestricted Subsidiaries will
not be subject to most of the restrictive covenants in the indenture. Our
Unrestricted Subsidiaries will not guarantee the notes. See "Risk Factors--
Risks Relating to Investment in the Notes."

Principal, Maturity and Interest

    Airgas issued $225.0 million of old notes on July 30, 2001. Airgas may
issue additional notes ("Additional Notes") under the indenture from time to
time after this offering with the same CUSIP numbers as the old notes and new
notes. Any offering of Additional Notes is subject to the covenant described
below under the caption "--Certain Covenants--Incurrence of Indebtedness and
Issuance of Preferred Stock." The old notes, the new notes and any Additional
Notes subsequently issued under the indenture will be treated as a single class
for all purposes under the indenture, including, without limitation, waivers,
amendments, redemptions and offers to purchase. Airgas will issue notes in
denominations of $1,000 and integral multiples of $1,000. The notes will mature
on October 1, 2011.

    Interest on the notes will accrue at the rate of 9.125% per annum and will
be payable semiannually in arrears on April 1 and October 1, commencing on
April 1, 2002. Airgas will make each interest payment to the Holders of record
on the immediately preceding March 15 and September 15.

    Interest on the notes will accrue from the date of original issuance or, if
interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

Methods of Receiving Payments on the Notes

    If a Holder has given wire transfer instructions to Airgas, Airgas will pay
all principal, interest and premium and Special Interest, if any, on that
Holder's notes in accordance with those

                                       27


instructions. All other payments on notes will be made at the office or agency
of the paying agent and registrar within the City and State of New York unless
Airgas elects to make interest payments by check mailed to the Holders at their
address set forth in the register of Holders.

Paying Agent and Registrar for the Notes

    The trustee under the indenture will initially act as paying agent and
registrar. Airgas may change the paying agent or registrar without prior notice
to the Holders of the notes, and Airgas or any of its Subsidiaries may act as
paying agent or registrar.

Transfer and Exchange

    A Holder may transfer or exchange notes in accordance with the indenture.
The registrar and the trustee may require a Holder to furnish appropriate
endorsements and transfer documents in connection with a transfer of notes.
Holders will be required to pay all taxes due on transfer. Airgas is not
required to transfer or exchange any note selected for redemption. Also, Airgas
is not required to transfer or exchange any note for a period of 15 days before
a selection of notes to be redeemed.

Subordination

Senior Debt versus Notes

    The payment of principal, interest and premium and Special Interest, if
any, on the notes will be subordinated to the prior payment in full in cash of
all Senior Debt of Airgas, including Senior Debt incurred after the date of the
indenture.

    The holders of Senior Debt will be entitled to receive payment in full in
cash of all Obligations due in respect of Senior Debt (including interest after
the commencement of any bankruptcy proceeding at the rate specified in the
applicable Senior Debt) before the Holders of notes will be entitled to receive
any payment with respect to the notes (except that Holders of notes may receive
and retain Permitted Junior Securities and payments made from the trust
described under "--Legal Defeasance and Covenant Defeasance" to the extent
permitted thereby), in the event of any distribution to creditors of Airgas:

      (1) in a liquidation or dissolution of Airgas;

      (2) in a bankruptcy, reorganization, insolvency, receivership or
  similar proceeding relating to Airgas or its property;

      (3) in an assignment for the benefit of creditors; or

      (4) in any marshaling of Airgas' assets and liabilities.

Liabilities of Subsidiaries versus Notes

    None of our Foreign Subsidiaries are guaranteeing the notes. Claims of
creditors of such non-guarantor Subsidiaries, including trade creditors holding
indebtedness or guarantees issued by such non-guarantor Subsidiaries, generally
will effectively have priority with respect to the assets and earnings of such
non-guarantor Subsidiaries over the claims of our creditors, including holders
of the notes, even if such claims do not constitute Senior Debt. Accordingly,
the notes will be effectively subordinated to creditors (including trade
creditors) and preferred stockholders, if any, of such non-guarantor
Subsidiaries.

    At March 31, 2001, after giving pro forma effect to the Refinancing
Transactions, the total liabilities of Airgas' Subsidiaries (other than the
Guarantors) would have been approximately $63 million, including trade
payables. Although the indenture limits the incurrence of Indebtedness

                                       28


and preferred stock of certain of our Subsidiaries, each such limitation is
subject to a number of significant qualifications. Moreover, the indenture does
not impose any limitation on the incurrence by such Subsidiaries of liabilities
that are not considered Indebtedness or preferred stock under the indenture.
See "--Certain Covenants--Certain Covenants Incurrence of Indebtedness and
Issuance of Preferred Stock."

Other Senior Subordinated Indebtedness versus Notes

    Only Indebtedness of Airgas or any of its Subsidiaries that is Senior Debt
of such Person ranks senior to the notes or the relevant Subsidiary Guarantee,
as the case may be, in accordance with the provisions of the indenture. The
notes and each Subsidiary Guarantee rank pari passu with all other Senior
Subordinated Indebtedness of Airgas and the relevant Subsidiary, respectively.

    Airgas and the Guarantors have agreed in the indenture that Airgas and such
Guarantors will not incur, directly or indirectly, any Indebtedness that is
contractually subordinate or junior in right of payment to Airgas' Senior Debt,
or the Senior Debt of such Guarantors, unless such Indebtedness is Senior
Subordinated Indebtedness of such Person or is expressly subordinated in right
of payment to Senior Subordinated Indebtedness of such Person. The indenture
does not treat unsecured Indebtedness as subordinated or junior to Secured
Indebtedness merely because it is unsecured.

Payment of Notes

    Airgas also may not make any payment in respect of the notes (except in
Permitted Junior Securities or from the trust described under "--Legal
Defeasance and Covenant Defeasance" when permitted thereby) if:

      (1) a default in the payment of the principal (including reimbursement
  obligations in respect of letters of credit) of or interest on or
  commitment, letter of credit or administrative fees relating to Senior
  Debt occurs and is continuing beyond any applicable grace period; or

      (2) any other default occurs and is continuing on any series of
  Designated Senior Debt that permits holders of that series of Designated
  Senior Debt to accelerate its maturity and the trustee receives a notice
  of such default (a "Payment Blockage Notice") from the holders of any such
  Designated Senior Debt (or their representative).

    Payments on the notes will be resumed:

      (1) in the case of a payment default, upon the date on which such
  default is cured or waived; and

      (2) in the case of a nonpayment default, upon the earlier of the date
  on which such nonpayment default is cured or waived or 179 days after the
  date on which the applicable Payment Blockage Notice is received, unless
  the maturity of any Designated Senior Debt has been accelerated.

    No new Payment Blockage Notice may be delivered unless and until:

      (1) 360 days have elapsed since the delivery of the immediately prior
  Payment Blockage Notice; and

      (2) all scheduled payments of principal, interest and premium and
  Special Interest, if any, on the notes that have come due have been paid
  in full in cash.

    No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the trustee will be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default has been
cured or waived for a period of not less than 180 days.

                                       29


    If the trustee or any Holder of the notes receives a payment in respect of
the notes (except in Permitted Junior Securities or from the trust described
under "--Legal Defeasance and Covenant Defeasance") when:

      (1) the payment is prohibited by these subordination provisions; and

      (2) the trustee or the Holder has actual knowledge that the payment is
  prohibited;

the trustee or the Holder, as the case may be, will hold the payment in trust
for the benefit of the holders of Senior Debt. Upon the proper written request
of the holders of Senior Debt, the trustee or the Holder, as the case may be,
will deliver the amounts in trust to the holders of Senior Debt or their proper
representative.

    Airgas must promptly notify holders of Senior Debt if payment of the notes
is accelerated because of an Event of Default.

    As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of Airgas, Holders of notes may
recover less ratably than creditors of Airgas who are holders of Senior Debt.
See "Risk Factors--The notes will be contractually junior in right of payment
to all of our senior indebtedness and the subsidiary guarantees will be
contractually junior in right of payment to all senior indebtedness of the
subsidiary guarantors."

Subsidiary Guarantees

    The notes are and will be guaranteed on an unsecured senior subordinated
basis by each of Airgas' current and future Domestic Restricted Subsidiaries
that guarantee the obligations under the New Credit Facility. These Subsidiary
Guarantees are joint and several obligations of the Guarantors. Each Subsidiary
Guarantee is subordinated to the prior payment in full of all Senior Debt of
that Guarantor, including Senior Debt incurred after the date of the indenture,
on the same basis as provided above with respect to the subordination of
payments on the notes by Airgas to the prior payment in full of Senior Debt.
The obligations of each Guarantor under its Subsidiary Guarantee is limited as
necessary to prevent that Subsidiary Guarantee from constituting a fraudulent
conveyance under applicable law. See "Risk Factors--Risks Relating to the
Notes--U.S. bankruptcy or fraudulent conveyance law may interfere with the
payment of the subsidiary guarantees." Except as described below under "--
Repurchase at the Option of Holders--Asset Sales" and "--Certain Covenants,"
Airgas is not restricted from selling or otherwise disposing of any of its
direct or indirect Equity Interests in the Guarantors.

    A Guarantor may not sell or otherwise dispose of all or substantially all
of its assets to, or consolidate with or merge with or into (whether or not
such Guarantor is the surviving Person), another Person, other than Airgas or
another Guarantor, unless:

      (1) immediately after giving effect to that transaction, no Default
  exists; and

      (2) either:

         (a) the Person acquiring the property in any such sale or
     disposition or the Person formed by or surviving any such
     consolidation or merger assumes all the obligations of that Guarantor
     under the indenture, its Subsidiary Guarantee and the registration
     rights agreement pursuant to a supplemental indenture reasonably
     satisfactory to the trustee; or

         (b) the Net Proceeds of such sale or other disposition are applied
     in accordance with the applicable provisions of the indenture.

                                       30


    The Subsidiary Guarantee of a Guarantor will be released and the Guarantor
relieved of any Obligations under its Guarantee:

      (1) in connection with any sale or other disposition of all or
  substantially all of the assets of that Guarantor (including by way of
  merger or consolidation) to a Person that is not (either before or after
  giving effect to such transaction) a Restricted Subsidiary of Airgas, if
  the sale or other disposition complies with the "Asset Sale" provisions of
  the indenture;

      (2) in connection with any sale of all of the Capital Stock of a
  Guarantor to a Person that is not (either before or after giving effect to
  such transaction) a Restricted Subsidiary of Airgas, if the sale complies
  with the "Asset Sale" provisions of the indenture;

      (3) the Legal Defeasance or Covenant Defeasance of the notes in
  accordance with the terms of the indenture; or

      (4) if Airgas designates such Guarantor as an Unrestricted Subsidiary
  in accordance with the applicable provisions of the indenture.

See "--Repurchase at the Option of Holders--Asset Sales."

Optional Redemption

    At any time on or prior to October 1, 2004, Airgas may at its option on any
one or more occasions redeem notes (which includes Additional Notes, if any) in
an aggregate principal amount not to exceed 35% of the aggregate principal
amount of notes (which includes Additional Notes, if any) issued under the
indenture at a redemption price of 109.125% of the principal amount, plus
accrued and unpaid interest and Special Interest, if any, to the redemption
date, with the net cash proceeds of one or more Public Equity Offerings;
provided that:

      (1) at least 65% of the aggregate principal amount of notes (which
  includes Additional Notes, if any) issued under the indenture remains
  outstanding immediately after the occurrence of such redemption (excluding
  notes held by Airgas and its Subsidiaries); and

      (2) the redemption occurs within 90 days of the date of the closing of
  such Public Equity Offering.

    At any time prior to October 1, 2006, Airgas may also redeem all or a part
of the notes, upon not less than 30 nor more than 60 days prior notice, at a
redemption price equal to 100% of the principal amount of notes redeemed plus
the Applicable Premium as of, and accrued and unpaid interest and Special
Interest, if any, to, the date of redemption (the "Redemption Date").

    On and after October 1, 2006, Airgas may at its option redeem all or a part
of the notes upon not less than 30 nor more than 60 days' prior notice, at the
redemption prices (expressed as percentages of principal amount) set forth
below plus accrued and unpaid interest and Special Interest, if any, on the
notes redeemed, to the applicable redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), if redeemed during the twelve-month period
beginning on October 1 of the years indicated below:



       Year                                                           Percentage
       ----                                                           ----------
                                                                   
       2006..........................................................  104.563%
       2007..........................................................  103.042%
       2008..........................................................  101.521%
       2009 and thereafter...........................................  100.000%



                                       31


Selection and Notice

    If less than all of the notes are to be redeemed at any time, the trustee
will select notes for redemption as follows:

      (1) if the notes are listed on any national securities exchange, in
  compliance with the requirements of the principal national securities
  exchange on which the notes are listed; or

      (2) if the notes are not listed on any national securities exchange,
  on a pro rata basis, by lot or by such method as the trustee deems fair
  and appropriate.

    No notes of $1,000 or less can be redeemed in part. Notices of redemption
will be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of notes to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior
to a redemption date if the notice is issued in connection with a defeasance of
the notes or a satisfaction and discharge of the indenture. Notices of
redemption may not be conditional.

    If any note is to be redeemed in part only, the notice of redemption that
relates to that note will state the portion of the principal amount of that
note that is to be redeemed. A new note in principal amount equal to the
unredeemed portion of the original note will be issued in the name of the
Holder of notes upon cancellation of the original note. Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on notes or portions of them called
for redemption.

Mandatory Redemption; Offers to Purchase; Open Market Purchases

    We are not required to make any mandatory redemption or sinking fund
payments with respect to the notes. However, under certain circumstances, we
may be required to offer to purchase notes as described under the captions "--
Repurchase of Notes at the Option of Holders--Asset Sales" and "--Change of
Control." We may at any time and from time to time purchase notes in the open
market or otherwise.

Repurchase at the Option of Holders

Change of Control

    If a Change of Control occurs, each Holder of notes will have the right to
require Airgas to repurchase all or any part (equal to $1,000 or an integral
multiple of $1,000) of that Holder's notes validly tendered pursuant to the
offer described below (the "Change of Control Offer"). The offer price in any
Change of Control Offer will be payable in cash and will be equal to 101% of
the aggregate principal amount of notes repurchased plus accrued and unpaid
interest and Special Interest, if any, on the notes repurchased, to the date of
purchase (the "Change of Control Payment"). Within 30 days following any Change
of Control, Airgas will mail a notice to each Holder describing the transaction
or transactions that constitute the Change of Control and offering to
repurchase notes on the Change of Control Payment Date specified in the notice
(the "Change of Control Payment Date"), which date will be no earlier than 30
days and no later than 60 days from the date such notice is mailed, pursuant to
the procedures required by the indenture and described in such notice. Airgas
will comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and
regulations are applicable in connection with the repurchase of the notes as a
result of a Change of Control. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of the indenture
relating to a Change of Control Offer, Airgas will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the indenture by virtue of such conflict.

                                       32


    On the Change of Control Payment Date, Airgas will, to the extent lawful:

      (1) accept for payment all notes or portions of notes properly
  tendered pursuant to the Change of Control Offer;

      (2) deposit with the paying agent an amount equal to the Change of
  Control Payment in respect of all notes or portions of notes properly
  tendered; and

      (3) deliver or cause to be delivered to the trustee the notes properly
  accepted together with an officers' certificate stating the aggregate
  principal amount of notes or portions of notes being purchased by Airgas.

    The paying agent will promptly mail to each Holder of notes properly
tendered the Change of Control Payment for such notes, and the trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new note equal in principal amount to any unpurchased portion of
the notes surrendered, if any; provided that each new note will be in a
principal amount of $1,000 or an integral multiple of $1,000.

    Prior to complying with any of the provisions of this "Change of Control"
covenant, but in any event within 90 days following a Change of Control, Airgas
will either repay all outstanding Senior Debt or obtain the requisite consents,
if any, under all agreements governing outstanding Senior Debt to permit the
repurchase of notes required by this covenant. Airgas will publicly announce
the results of the Change of Control Offer on or as soon as practicable after
the Change of Control Payment Date.

    The provisions described above that require Airgas to make a Change of
Control Offer following a Change of Control will be applicable whether or not
any other provisions of the indenture are applicable. Except as described above
with respect to a Change of Control, the indenture does not contain provisions
that permit the Holders of the notes to require that Airgas repurchase or
redeem the notes in the event of a takeover, recapitalization or other similar
transaction.

    Airgas will not be required to make a Change of Control Offer upon a Change
of Control if a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in the
indenture applicable to a Change of Control Offer made by Airgas and purchases
all notes properly tendered and not withdrawn under the Change of Control
Offer.

    The Change of Control purchase feature of the notes may in certain
circumstances make more difficult or discourage a sale or takeover of Airgas
and, thus, the removal of incumbent management. The Change of Control purchase
feature is a result of negotiations between Airgas and the initial purchasers.
We have no present intention to engage in a transaction involving a Change of
Control, although it is possible that we could decide to do so in the future.
Subject to the limitations discussed below, we could, in the future, enter into
certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
indenture, but that could increase the amount of Indebtedness outstanding at
such time or otherwise affect our capital structure or credit ratings.
Restrictions on Airgas' ability to incur additional Indebtedness are contained
in the covenants described under "Certain Covenants Incurrence of Indebtedness
and Issuance of Preferred Stock." Such restrictions can only be waived with the
consent of the Holders of a majority in principal amount of the notes then
outstanding. Except for the limitations contained in such covenants, however,
the indenture will not contain any covenants or provisions that may afford
Holders of the notes protection in the event of a highly leveraged transaction.

    The definition of Change of Control includes a phrase relating to the
direct or indirect sale, lease, transfer, conveyance or other disposition of
"all or substantially all" of the properties or assets

                                       33


of Airgas and its Restricted Subsidiaries taken as a whole. Although there is a
limited body of case law interpreting the phrase "substantially all," there is
no precise established definition of the phrase under applicable law.
Accordingly, the ability of a Holder of notes to require Airgas to repurchase
its notes as a result of a sale, lease, transfer, conveyance or other
disposition of less than all of the assets of Airgas and its Restricted
Subsidiaries taken as a whole to another Person or group may be uncertain.

    The provisions under the indenture relating to Airgas' obligation to make
an offer to repurchase the notes as a result of a Change of Control may be
waived or modified with the written consent of the Holders of a majority in
principal amount of the notes then outstanding.

Asset Sales

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

      (1) Airgas (or the Restricted Subsidiary, as the case may be) receives
  consideration at the time of the Asset Sale at least equal to the fair
  market value of the assets or Equity Interests issued or sold or otherwise
  disposed of; and

      (2) at least 75% of the consideration received in the Asset Sale by
  Airgas or such Restricted Subsidiary is in the form of cash or Cash
  Equivalents.

    For purposes of this provision, each of the following will be deemed to be
cash or Cash Equivalents:

      (a) any liabilities, as shown on Airgas' or such Restricted
  Subsidiary's most recent balance sheet, of Airgas or any Restricted
  Subsidiary (other than contingent liabilities and liabilities that are by
  their terms subordinated to the notes or any Subsidiary Guarantee) that
  are assumed by the transferee of any such assets and the lender releases
  Airgas or such Restricted Subsidiary from further liability; and

      (b) any securities, notes or other obligations received by Airgas or
  any such Restricted Subsidiary from such transferee that are promptly
  converted by Airgas or such Restricted Subsidiary into cash or Cash
  Equivalents, to the extent of the cash or Cash Equivalents received in
  that conversion.

    Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
Airgas, or the Restricted Subsidiaries, as the case may be, may apply an amount
equal to such Net Proceeds at its option:

      (1) to repay any Senior Debt of Airgas or any of its Restricted
  Subsidiaries;

      (2) to acquire (or enter into a binding agreement to acquire, provided
  that such commitment shall be subject only to customary conditions (other
  than financing) and such acquisition shall be consummated within 180 days
  after the end of such 365 day period) the assets of, or a majority of the
  Voting Stock of, a Permitted Business or the minority interest in any
  Restricted Subsidiary;

      (3) to make a capital expenditure; or

      (4) to acquire (or enter into a binding agreement to acquire, provided
  that such commitment shall be subject only to customary conditions (other
  than financing) and such acquisition shall be consummated within 180 days
  after the end of such 365 day period) other long-term assets that are used
  or useful in a Permitted Business.


                                       34


    If an amount equal to the Net Proceeds from Asset Sales is not applied or
invested as provided in the preceding paragraph such amount will constitute
"Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $25.0
million, Airgas will make an offer to holders of the notes (and to holders of
other Senior Subordinated Indebtedness of Airgas designated by Airgas) to
purchase notes (and such other Senior Subordinated Indebtedness of Airgas)
pursuant to and subject to the conditions contained in the indenture (the
"Asset Sale Offer"). Airgas will purchase notes tendered pursuant to the Asset
Sale Offer at a purchase price of 100% of their principal amount (or, in the
event such other Senior Subordinated Indebtedness of Airgas was issued with
significant original issue discount, 100% of the accreted value thereof)
without premium, plus accrued but unpaid interest (or, in respect of such
other Senior Subordinated Indebtedness of Airgas, such lesser price, if any,
as may be provided for by the terms of such Senior Subordinated Indebtedness)
in accordance with the procedures (including prorating in the event of
oversubscription) set forth in the indenture (the "Asset Sale Offer Price").
If the aggregate purchase price of the securities tendered exceeds the Net
Proceeds allotted to their purchase, Airgas will select the securities to be
purchased on a pro rata basis but in round denominations, which in the case of
the notes will be denominations of $1,000 principal amount or multiples
thereof. If any Excess Proceeds remain after consummation of an Asset Sale
Offer, Airgas may use those Excess Proceeds for any purpose not otherwise
prohibited by the indenture. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds will be reset at zero.

    Airgas will comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with each repurchase
of notes pursuant to an Asset Sale Offer. To the extent that the provisions of
any securities laws or regulations conflict with the Asset Sale provisions of
the indenture, Airgas will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under the
Asset Sale provisions of the indenture by virtue of such conflict.

    The agreements governing Airgas' outstanding Senior Debt currently
prohibit Airgas from purchasing any notes, and also provides that certain
change of control events with respect to Airgas would constitute a default
under these agreements. Any future credit agreements or other agreements
relating to indebtedness to which Airgas becomes a party may contain similar
restrictions and provisions. In the event a Change of Control Offer or Asset
Sale Offer would require Airgas to purchase notes when it is prohibited from
doing so, Airgas could seek the consent of its senior lenders to the purchase
of notes or could attempt to refinance the borrowings that contain such
prohibition. If Airgas does not obtain such a consent or repay such
borrowings, Airgas will remain prohibited from purchasing notes. In such case,
Airgas' failure to purchase tendered notes would constitute an Event of
Default under the indenture, which would, in turn, constitute a default under
its other indebtedness. In such circumstances, the subordination provisions in
the indenture would likely restrict payments to the Holders of notes. See
"Risk Factors--We may not have sufficient funds to purchase notes upon a
change of control."

Certain Covenants

    Set forth below are summaries of certain covenants contained in the
indenture. Following the first day that:

      (a) the notes have an Investment Grade Rating from both of the Rating
  Agencies, and

      (b) no Default has occurred and is continuing under the indenture.

    Airgas and its Restricted Subsidiaries will not be subject to the
provisions of the indenture summarized under the subcaptions:

  .  ""--Repurchase at the Option of the Holders--Asset Sales"

                                      35


  .  ""--Certain Covenants--Incurrence of Indebtedness and Issuance of
     Preferred Stock"

  .  ""--Certain Covenants--Restricted Payments"

  .  ""--Certain Covenants--Dividend and Other Payment Restrictions
     Affecting Restricted Subsidiaries"

  .  ""--Certain Covenants--Merger, Consolidation or Sale of Assets" (but
     only clause (4) of such covenant)

  .  ""--Certain Covenants--Transactions with Affiliates"

(collectively, the "Suspended Covenants"). In the event that Airgas and its
Restricted Subsidiaries are not subject to the Suspended Covenants for any
period of time as a result of the preceding sentence, and subsequently one or
both of the Rating Agencies downgrades the rating assigned to the notes below
an Investment Grade Rating, then Airgas and the Restricted Subsidiaries will
thereafter again be subject to the Suspended Covenants, and compliance with
the Suspended Covenants with respect to Restricted Payments made after the
time of such downgrade will be calculated in accordance with the terms of the
covenant described below under "Restricted Payments" as though such covenant
had been in effect since the date the notes were originally issued.

Restricted Payments

    Airgas will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly:

      (1) declare or pay any dividend or make any other payment or
  distribution on account of Airgas' or any of its Restricted Subsidiaries'
  Equity Interests (including, without limitation, any payment in connection
  with any merger or consolidation involving Airgas or any of its Restricted
  Subsidiaries) or to the direct or indirect holders of Airgas' or any of
  its Restricted Subsidiaries' Equity Interests in their capacity as such
  (other than dividends or distributions payable (i) in Equity Interests
  (other than Disqualified Stock) of Airgas or (ii) to Airgas or a
  Restricted Subsidiary of Airgas);

      (2) purchase, redeem or otherwise acquire or retire for value
  (including, without limitation, in connection with any merger or
  consolidation involving Airgas) any Equity Interests of Airgas (other than
  any such Equity Interests owned by Airgas or any of its Restricted
  Subsidiaries);

      (3) make any payment on or with respect to, or purchase, redeem,
  defease or otherwise acquire or retire for value any Indebtedness that is
  subordinated to the notes or the Subsidiary Guarantees, except a payment
  of interest or principal at the Stated Maturity thereof; or

      (4) make any Restricted Investment (all such payments and other
  actions set forth in these clauses (1) through (4) above being
  collectively referred to as "Restricted Payments"),

unless, at the time of and after giving effect to such Restricted Payment:

      (a) no Default has occurred and is continuing or would occur as a
  consequence of such Restricted Payment;

      (b) Airgas would, after giving pro forma effect thereto as if such
  Restricted Payment had been made at the beginning of the applicable four-
  quarter period, have been permitted to incur at least $1.00 of additional
  Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
  the first paragraph of the covenant described below under the caption "--
  Incurrence of Indebtedness and Issuance of Preferred Stock;" and

      (c) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments made by Airgas and its Restricted Subsidiaries
  after the date of the indenture (excluding Restricted Payments permitted
  by clauses (2) through (8) of the next succeeding paragraph), is less than
  the sum, without duplication, of:

                                      36


         (i) 50% of the Consolidated Net Income of Airgas for the period
     (taken as one accounting period) from the beginning of the fiscal
     quarter immediately preceding the fiscal quarter in which the date of
     the indenture occurs to the end of Airgas' most recently ended fiscal
     quarter for which internal financial statements are available at the
     time of such Restricted Payment (or, if such Consolidated Net Income
     for such period is a deficit, less 100% of such deficit), plus

         (ii) 100% of the aggregate net cash proceeds received by Airgas
     since the date of the indenture as a contribution to its common equity
     capital or from the issue or sale of Equity Interests of Airgas (other
     than Disqualified Stock) or from the issue or sale of convertible or
     exchangeable Disqualified Stock or convertible or exchangeable debt
     securities of Airgas that have been converted into or exchanged for
     such Equity Interests (other than Equity Interests, Disqualified Stock
     or debt securities sold to a Subsidiary of Airgas), plus

         (iii) to the extent that any Restricted Investment that was made
     after the date of the indenture is sold for cash or otherwise
     liquidated or repaid, purchased or redeemed for cash, the lesser of
     (i) such cash (less the cost of disposition, if any) and (ii) the
     amount of such Restricted Investment, plus

         (iv)to the extent that any Unrestricted Subsidiary of Airgas is
     redesignated as a Restricted Subsidiary after the date of the
     indenture, the lesser of (i) the fair market value of Airgas'
     Investment in such Subsidiary as of the date of such redesignation and
     (ii) such fair market value as of the date on which such Subsidiary
     was originally designated as an Unrestricted Subsidiary.

    The preceding provisions will not prohibit:

      (1) the payment of any dividend or distribution on, or redemption of,
  Equity Interests, within 60 days after the date of declaration or notice
  thereof, if at the date of declaration or the giving of such notice, the
  payment would have complied with the provisions of the indenture;

      (2) any Restricted Payment made in exchange for, or made out of the
  net cash proceeds of, the substantially concurrent sale (other than to a
  Restricted Subsidiary of Airgas) of, Equity Interests of Airgas (other
  than Disqualified Stock), provided that the amount of any such net cash
  proceeds that are utilized for any such Restricted Payment will be
  excluded from clause (c)(ii) of the preceding paragraph;

      (3) the defeasance, redemption, repurchase or other acquisition of
  subordinated Indebtedness of Airgas or any Guarantor with the net cash
  proceeds from an incurrence of Permitted Refinancing Indebtedness;

      (4) the payment of any dividend or other payment or distribution by a
  Restricted Subsidiary of Airgas to the holders of its Equity Interests on
  a pro rata basis;

      (5) repurchases of Equity Interests deemed to occur upon exercise of
  stock options if those Equity Interests represent all or a portion of the
  exercise price of those options;

      (6) the repurchase, redemption or other acquisition or retirement for
  value of any Equity Interests of Airgas or any Restricted Subsidiary of
  Airgas (in the event such Equity Interests are not owned by Airgas or any
  of its Restricted Subsidiaries) in an amount not to exceed $5.0 million in
  any fiscal year, so long as no Default has occurred and is continuing or
  would be caused thereby;

      (7) the purchase by Airgas of fractional shares arising out of stock
  dividends, splits or combinations or business combinations;

      (8) distributions or payments of Receivables Fees; or

                                       37


      (9) Restricted Payments not to exceed $25.0 million under this clause
  (9) in the aggregate, plus, to the extent Restricted Payments made
  pursuant to this clause (9) are Investments made by Airgas or any of its
  Restricted Subsidiaries in any Person and such Investment is sold for cash
  or otherwise liquidated or repaid, purchased or redeemed for cash, an
  amount equal to the lesser of (i) such cash (less the cost of disposition,
  if any) and (ii) the amount of such Restricted Payment, provided, that (i)
  at the time of such Restricted Payment, no Default shall have occurred and
  be continuing (or result therefrom) and (ii) the amount of such cash will
  be excluded from clause (c)(iv) of the preceding paragraph.

    The amount of all Restricted Payments (other than cash) will be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Airgas or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
covenant will be determined by the Board of Directors of Airgas, whose
determination will be conclusive.

Incurrence of Indebtedness and Issuance of Preferred Stock

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect
to (collectively, "incur") any Indebtedness (including Acquired Debt), and
Airgas will not, and will not permit any Guarantor to, issue any Disqualified
Stock and will not permit any of its Restricted Subsidiaries to issue any
shares of preferred stock, provided, that Airgas may incur Indebtedness
(including Acquired Debt) or issue Disqualified Stock, and Airgas' Restricted
Subsidiaries may incur Indebtedness (including Acquired Debt) or issue
preferred stock, in each case, if the Fixed Charge Coverage Ratio for Airgas'
most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock or preferred
stock is issued would have been at least 2.0 to 1, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred or the Disqualified Stock or
preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period.

    The first paragraph of this covenant will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted Debt"):

      (1) the incurrence by Airgas and any of its Restricted Subsidiaries of
  Indebtedness and letters of credit under Credit Facilities in an aggregate
  principal amount at any one time outstanding under this clause (1) (with
  letters of credit being deemed to have a principal amount equal to the
  maximum potential liability of Airgas and its Restricted Subsidiaries
  thereunder) not to exceed the greater of (x) $550.0 million or (y) the
  amount of the Borrowing Base as of the date of such incurrence;

      (2) the incurrence by Airgas and its Restricted Subsidiaries of the
  Existing Indebtedness;

      (3) the incurrence by Airgas and the Guarantors of Indebtedness
  represented by the old notes and the related Subsidiary Guarantees to be
  issued, in the case of the old notes, on the date of the indenture and the
  new notes and the related Subsidiary Guarantees to be issued pursuant to
  the registration rights agreement;

      (4) the incurrence by Airgas or any of its Restricted Subsidiaries of
  Indebtedness represented by Capital Lease Obligations, mortgage financings
  or purchase money obligations, in each case, incurred for the purpose of
  financing all or any part of the purchase price or cost of construction or
  improvement of property, plant or equipment used in the business of Airgas
  or such Restricted Subsidiary, in an aggregate principal amount, including
  all Permitted

                                       38


  Refinancing Indebtedness incurred to refund, refinance or replace any
  Indebtedness incurred pursuant to this clause (4), not to exceed $25.0
  million at any time outstanding;

      (5) the incurrence by Airgas or any of its Restricted Subsidiaries of
  Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
  which are used to refund, refinance or replace Indebtedness (other than
  intercompany Indebtedness) that was permitted by the indenture to be
  incurred under the first paragraph of this covenant or clauses (2), (3),
  (4), (5) or (11) of this paragraph;

      (6) the incurrence by Airgas or any of its Restricted Subsidiaries of
  Indebtedness owing to Airgas, any of its Restricted Subsidiaries or any
  Accounts Receivable Subsidiary, provided that:

         (a) if Airgas or any Guarantor is the obligor on any such
     Indebtedness owing to any Restricted Subsidiary, such Indebtedness
     must be expressly subordinated to the prior payment in full in cash of
     all Obligations with respect to the notes, in the case of Airgas, or
     the Subsidiary Guarantee, in the case of a Guarantor; and

         (b) (i) any subsequent issuance or transfer of Equity Interests
     that results in any such Indebtedness being held by a Person other
     than Airgas, a Restricted Subsidiary of Airgas or an Accounts
     Receivable Entity and (ii) any sale or other transfer of any such
     Indebtedness to a Person that is not Airgas, a Restricted Subsidiary
     of Airgas or an Accounts Receivable Entity will be deemed, in each
     case, to constitute an incurrence of such Indebtedness by Airgas or
     such Restricted Subsidiary, as the case may be, that was not permitted
     by this clause (6);

      (7) the incurrence by Airgas or any of its Restricted Subsidiaries of
  Hedging Obligations;

      (8) the guarantee by Airgas or any of the Restricted Subsidiaries of
  Indebtedness of Airgas or a Restricted Subsidiary of Airgas that was
  permitted to be incurred by another provision of this covenant;

      (9) Obligations in respect of performance, bid and surety bonds and
  completion guarantees provided by Airgas or any Restricted Subsidiary in
  the ordinary course of business;

      (10) Indebtedness arising from the honoring by a bank or other
  financial institution of a check, draft or similar instrument drawn
  against insufficient funds in the ordinary course of business, provided,
  that such Indebtedness is extinguished within five Business Days of its
  incurrence; and

      (11) the incurrence by Airgas or any of its Restricted Subsidiaries of
  additional Indebtedness in an aggregate principal amount (or accreted
  value, as applicable) which, when taken together with all other
  Indebtedness of Airgas and its Restricted Subsidiaries outstanding on the
  date of such incurrence and incurred pursuant to this clause (11), does
  not exceed $25.0 million.

    For purposes of determining compliance with this "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant, in the event that an
item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (1) through (11) above, or
is entitled to be incurred pursuant to the first paragraph of this covenant,
Airgas will be permitted to divide and classify such item of Indebtedness on
the date of its incurrence, or later reclassify all or a portion of such item
of Indebtedness, in any manner that complies with this covenant. Indebtedness
under Credit Facilities outstanding on the date on which notes are first
issued and authenticated under the indenture will be deemed to have been
incurred on such date in reliance on the exception provided by clause (1) of
the definition of Permitted Debt.

    Accrual of interest and dividends, accretion or amortization of original
issue discount and changes to amounts outstanding in respect of Hedging
Obligations solely as a result of fluctuations in

                                      39


foreign currency exchange rates or interest rates or by reason of fees,
indemnities and compensation payable thereunder, will not be deemed to be an
incurrence of Indebtedness or an issuance of preferred stock for purpose of
this covenant.

    For purposes of determining compliance with any U.S. dollar denominated
restriction on the incurrence of Indebtedness where the Indebtedness incurred
is denominated in a currency other than U.S. dollars, the amount of such
Indebtedness will be the U.S. Dollar Equivalent of such Indebtedness determined
on the date of incurrence, provided, that if any such Indebtedness denominated
in a currency other than U.S. dollars is subject to a Currency Agreement with
respect to U.S. dollars covering all principal, premium, if any, and interest
payable on such Indebtedness, the amount of such Indebtedness expressed in U.S.
dollars will be as provided in such Currency Agreement. The principal amount of
any Permitted Refinancing Indebtedness incurred in the same currency as the
Indebtedness being refinanced will be the U.S. Dollar Equivalent of the
Indebtedness being refinanced, except to the extent that (i) such U.S. Dollar
Equivalent was determined based on a Currency Agreement, in which case the
Permitted Refinancing Indebtedness will be determined in accordance with the
preceding sentence, and (ii) the principal amount of the Permitted Refinancing
Indebtedness exceeds the principal amount of the Indebtedness being refinanced,
in which case the U.S. Dollar Equivalent of such excess will be determined on
the date such Permitted Refinancing Indebtedness is incurred.

Anti-Layering

    Airgas will not incur, create, issue, assume, guarantee or otherwise become
liable for any Indebtedness that is subordinate or junior in right of payment
to any Senior Debt of Airgas and senior in any respect in right of payment to
the notes. No Guarantor will incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to the Senior Debt of such Guarantor and senior in any respect
in right of payment to such Guarantor's Subsidiary Guarantee.

Limitation on Liens

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
create, incur or otherwise cause or suffer to exist or become effective any
Liens of any kind upon any property or assets of Airgas or any Restricted
Subsidiary of Airgas, now owned or hereafter acquired, which secures
Indebtedness that ranks pari passu with or subordinate to the notes unless:

      (1) if such Lien secures Indebtedness which is pari passu with the
  notes, then the notes are secured on an equal and ratable basis with the
  Indebtedness so secured until such time as such Indebtedness is no longer
  secured by a Lien, or

      (2) if such Lien secures Indebtedness, which is subordinated to the
  notes, any such Lien shall be subordinated to a Lien granted to the
  holders of the notes in the same collateral as that securing such Lien to
  the same extent as such subordinated Indebtedness is subordinated to the
  notes.

Dividend and Other Payment Restrictions Affecting Subsidiaries

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, create or permit to exist or become effective any
consensual encumbrance or restriction on the ability of any of its Restricted
Subsidiaries to:

      (1) pay dividends or make any other distributions on its Capital Stock
  to Airgas or any of its Restricted Subsidiaries, or with respect to any
  other interest or participation in, or measured

                                       40


  by, its profits and payable to Airgas and any of its Restricted
  Subsidiaries, or pay any indebtedness owed to Airgas or any of its
  Restricted Subsidiaries;

      (2) make loans or advances to Airgas or any of its Restricted
  Subsidiaries; or

      (3) transfer any of its properties or assets to Airgas or any of its
  Restricted Subsidiaries.

    However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

      (1) any agreement in effect or entered into on the date of the
  indenture, including agreements governing Existing Indebtedness and the
  New Credit Facility as in effect on the date of the indenture and any
  amendments, modifications, restatements, renewals, increases, supplements,
  refundings, replacements or refinancings of those agreements, provided
  that the amendments, modifications, restatements, renewals, increases,
  supplements, refundings, replacement or refinancings are not materially
  less favorable, taken as a whole, with respect to such dividend and other
  payment restrictions than those contained in those agreements on the date
  of the indenture;

      (2) the indenture, the notes and the Subsidiary Guarantees;

      (3) applicable law and any applicable rule, regulation or order;

      (4) any instrument governing Indebtedness or Capital Stock of a Person
  acquired by Airgas or any of its Restricted Subsidiaries as in effect at
  the time of such acquisition (except to the extent such Indebtedness or
  Capital Stock was incurred in connection with or in contemplation of such
  acquisition), which encumbrance or restriction is not applicable to any
  Person, or the properties or assets of any Person, other than the Person,
  or the property or assets of the Person, so acquired, provided that, in
  the case of Indebtedness, such Indebtedness was permitted by the terms of
  the indenture to be incurred;

      (5) customary non-assignment provisions in leases, licenses or
  contracts entered into in the ordinary course of business;

      (6) purchase money obligations that impose restrictions on that
  property of the nature described in clause (3) of the preceding paragraph;

      (7) any agreement for the sale or other disposition of assets,
  including, without limitation, customary restrictions with respect to a
  Subsidiary pursuant to an agreement that has been entered into for the
  sale or disposition of Capital Stock or assets of that Subsidiary;

      (8) Permitted Refinancing Indebtedness, provided that the restrictions
  contained in the agreements governing such Permitted Refinancing
  Indebtedness are not materially less favorable, taken as a whole, than
  those contained in the agreements governing the Indebtedness being
  refinanced;

      (9) Liens that limit the right of the debtor to dispose of the assets
  subject to such Liens;

      (10) customary provisions in joint venture agreements, asset sale
  agreements, stock sale agreements and other similar agreements entered
  into in the ordinary course of business;

      (11) any such encumbrance or restriction with respect to a Foreign
  Subsidiary pursuant to an agreement governing Indebtedness incurred by
  such Foreign Subsidiary;

      (12) restrictions on cash or other deposits or net worth imposed by
  customers under contracts entered into in the ordinary course of business;

      (13) any agreement governing the terms of any Indebtedness incurred
  pursuant to clause (1) of the covenant described under "--Incurrence of
  Indebtedness and Issuance of Preferred Stock", provided, that (i) either
  (x) the encumbrance or restriction applies only in the event of

                                      41


  and during the continuance of a payment default or a default with respect
  to a financial covenant contained in such Indebtedness or agreement or (y)
  Airgas determines that, at the time any such Indebtedness is incurred (and
  at the time of any modification of the terms of any such encumbrance or
  restriction), any such encumbrance or restriction will not materially
  affect Airgas' ability to make principal or interest payments on the notes
  and (ii) the encumbrance or restriction is not materially more
  disadvantageous to the Holders of the notes than is customary in
  comparable financings or agreements (as determined by Airgas in good
  faith); and

      (14) restrictions created in connection with any Receivables Facility
  that, in the good faith determination of the Board of Directors of Airgas,
  are necessary or advisable to effect that Receivables Facility.

Merger, Consolidation or Sale of Assets

    Airgas may not, directly or indirectly: (1) consolidate or merge with or
into another Person (whether or not Airgas is the surviving corporation); or
(2) sell, assign, transfer, convey or otherwise dispose of all or substantially
all of the properties or assets of Airgas and its Restricted Subsidiaries taken
as a whole, in one or more related transactions, to another Person; unless:

      (1) either: (a) Airgas is the surviving corporation; or (b) the Person
  formed by or surviving any such consolidation or merger (if other than
  Airgas) or to which such sale, assignment, transfer, conveyance or other
  disposition has been made is a corporation organized or existing under the
  laws of the United States, any state of the United States or the District
  of Columbia (any such Person, the "Successor Company");

      (2) the Successor Company assumes all the obligations of Airgas under
  the notes, the indenture and the registration rights agreement pursuant to
  agreements reasonably satisfactory to the trustee;

      (3) immediately after such transaction no Default exists; and

      (4) Airgas or the Successor Company will, on the date of such
  transaction after giving pro forma effect thereto and any related
  financing transactions as if the same had occurred at the beginning of the
  applicable four quarter period, be permitted to incur at least $1.00 of
  additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
  set forth in the first paragraph of the covenant described above under the
  caption "--Incurrence of Indebtedness and Issuance of Preferred Stock."

    The foregoing clause (4) will not prohibit (a) a merger between Airgas and
any of its Restricted Subsidiaries or (b) a merger between Airgas and an
Affiliate incorporated solely for the purpose of reincorporating Airgas in
another state of the United States, so long as the amount of Indebtedness of
Airgas and its Restricted Subsidiaries is not increased thereby.

    In addition, Airgas may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This "Merger, Consolidation or Sale of
Assets" covenant will not apply to a sale, assignment, transfer, conveyance or
other disposition of assets between or among Airgas and any of the Guarantors.

    The Successor Company will be the successor to Airgas and shall succeed to,
and be substituted for, and may exercise every right and power of, Airgas under
the indenture, and the predecessor company shall be released from its
obligations with respect to the notes, including with respect to its obligation
to pay the principal of and interest and Special Interest, if any, on the
notes.


                                       42


Transactions with Affiliates

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
make any payment to, or sell, lease, transfer or otherwise dispose of any of
its properties or assets to, or purchase any property or assets from, or enter
into or make or amend any transaction, contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an
"Affiliate Transaction"), unless:

      (1) the Affiliate Transaction is on terms that are not materially less
  favorable to Airgas or the relevant Restricted Subsidiary than those that
  would have been obtained in a comparable transaction by Airgas or such
  Restricted Subsidiary with an unrelated Person; and

      (2) Airgas delivers to the trustee:

         (a) with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of
     $5.0 million, a resolution of the Board of Directors of Airgas set
     forth in an officers' certificate certifying that such Affiliate
     Transaction complies with this covenant and that such Affiliate
     Transaction has been approved by a majority of the disinterested
     members of the Board of Directors of Airgas; and

         (b) with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of
     $15.0 million, the Board of Directors of Airgas shall also have
     received a written opinion from an Independent Qualified Party to the
     effect that such Affiliate Transaction is fair, from a financial
     standpoint, to Airgas and its Restricted Subsidiaries or not
     materially less favorable to Airgas and its Restricted Subsidiaries
     than could reasonably be expected to be obtained at the time in an
     arm's-length transaction with a Person who was not an Affiliate.

    Notwithstanding the foregoing, the following items will not be deemed to be
Affiliate Transactions and, therefore, will not be subject to the provisions of
the prior paragraph:

      (1) any employment agreement entered into by Airgas or any of its
  Restricted Subsidiaries in the ordinary course of business of Airgas or
  such Restricted Subsidiary;

      (2) transactions between or among Airgas and/or its Restricted
  Subsidiaries;

      (3) transactions with a Person that is an Affiliate of Airgas solely
  because Airgas owns an Equity Interest in, or controls, such Person;

      (4) payment of reasonable directors fees;

      (5) the issuance or sale of Equity Interests (other than Disqualified
  Stock) of Airgas;

      (6) the pledge of Equity Interests of Unrestricted Subsidiaries to
  support the Indebtedness thereof;

      (7) Restricted Payments that are permitted by the provisions of the
  indenture described above under the caption "--Restricted Payments;" and

      (8) transfers of accounts receivable, or participations therein, in
  connection with any Receivables Facility.

Additional Subsidiary Guarantees

    Airgas will not permit any of its Restricted Subsidiaries that are Domestic
Subsidiaries, directly or indirectly, to guarantee or pledge any assets to
secure the payment of any other Indebtedness of Airgas unless such Restricted
Subsidiary simultaneously executes and delivers to the trustee a supplemental
indenture, in form and substance reasonably satisfactory to the trustee
pursuant to

                                       43


which such Restricted Subsidiary shall guarantee all of Airgas' obligations
under the notes, which Guarantee will be senior to or pari passu with such
Subsidiary's Guarantee of or pledge to secure such other Indebtedness unless
such other Indebtedness is Senior Debt, in which case the Guarantee of the
notes may be subordinated to the Guarantee of such Senior Debt to the same
extent as the notes are subordinated to such Senior Debt.

Designation of Restricted and Unrestricted Subsidiaries

    The Board of Directors of Airgas may designate any Restricted Subsidiary of
Airgas to be an Unrestricted Subsidiary if that designation would not cause a
Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate fair market value of all outstanding Investments
owned by Airgas and its Restricted Subsidiaries in the Subsidiary properly
designated will be deemed to be an Investment made as of the time of the
designation. That designation will only be permitted if the Investment would be
permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Board of Directors of Airgas may
redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the
redesignation would not cause a Default.

Payments for Consent

    Airgas will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder of notes for or as an inducement to any consent, waiver
or amendment of any of the terms or provisions of the indenture or the notes
unless such consideration is offered to be paid and is paid to all Holders of
the notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.

Reports

    Whether or not required by the Commission, so long as any notes are
outstanding, Airgas will furnish to the Holders of notes, within the time
periods specified in the Commission's rules and regulations:

      (1) all quarterly and annual financial information that would be
  required to be contained in a filing with the Commission on Forms 10-Q and
  10-K if Airgas were required to file such Forms, including a "Management's
  Discussion and Analysis of Financial Condition and Results of Operations"
  and, with respect to the annual information only, a report on the annual
  financial statements by Airgas' certified independent accountants; and

      (2) all current reports that would be required to be filed with the
  Commission on Form 8-K if Airgas were required to file such reports.

    In addition, whether or not required by the Commission, Airgas will file a
copy of all of the information and reports referred to in clauses (1) and (2)
above with the Commission for public availability within the time periods
specified in the Commission's rules and regulations (unless the Commission will
not accept such a filing) and make such information available to securities
analysts and prospective investors upon request.

    In addition, Airgas and the Guarantors have agreed that, for so long as any
notes remain outstanding, they will furnish to the Holders and to securities
analysts and prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

    If Airgas has designated any of its Subsidiaries as Unrestricted
Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph will include a reasonably

                                       44


detailed presentation, either on the face of the financial statements or in the
footnotes thereto, and in Management's Discussion and Analysis of Financial
Condition and Results of Operations, of the financial condition and results of
operations of Airgas and its Restricted Subsidiaries separate from the
financial condition and results of operations of the Unrestricted Subsidiaries
of Airgas.

Events of Default and Remedies

    Each of the following is an Event of Default:

      (1) default for 30 days in the payment when due of interest on, or
  Special Interest with respect to, the notes whether or not prohibited by
  the subordination provisions of the indenture;

      (2) default in payment when due of the principal of, or premium, if
  any, on the notes, whether or not prohibited by the subordination
  provisions of the indenture;

      (3) failure by Airgas to comply with the provisions described under
  the caption "--Certain Covenants--Merger, Consolidation or Sale of
  Assets;"

      (4) failure by Airgas or any of its Restricted Subsidiaries to comply
  for 30 days after receipt of notice with the provisions described under
  the captions "--Repurchase at the Option of Holders--Change of Control,"
  "--Repurchase at the Option of Holders--Asset Sales," "--Certain
  Covenants--Restricted Payments" or "--Certain Covenants--Incurrence of
  Indebtedness and Issuance of Preferred Stock;"

      (5) failure by Airgas or any of its Restricted Subsidiaries for 60
  days after notice to comply with any of the other agreements in the
  indenture;

      (6) default under any mortgage, indenture or instrument under which
  there may be issued or by which there may be secured or evidenced any
  Indebtedness for money borrowed by Airgas or any of its Restricted
  Subsidiaries that are Significant Subsidiaries (or the payment of which is
  guaranteed by Airgas or any of its Restricted Subsidiaries that are
  Significant Subsidiaries) whether such Indebtedness or guarantee now
  exists, or is created after the date of the indenture, if that default:

         (a) is caused by a failure to pay principal at its stated maturity
     after giving effect to any applicable grace period provided in such
     Indebtedness (a "Payment Default"); or

         (b) results in the acceleration of such Indebtedness prior to its
     express maturity,

  and, in each case, the principal amount of any such Indebtedness, together
  with the principal amount of any other such Indebtedness under which there
  has been a Payment Default or the maturity of which has been so
  accelerated, aggregates $25.0 million or more;

      (7) failure by Airgas or any of its Restricted Subsidiaries to pay
  final judgments aggregating in excess of $25.0 million, which judgments
  are not paid, discharged or stayed for a period of 60 days;

      (8) certain events of bankruptcy, insolvency or reorganization of
  Airgas or a Restricted Subsidiary of Airgas that is a Significant
  Subsidiary; and

      (9) except as permitted by the indenture, any Subsidiary Guarantee
  shall be held in any judicial proceeding to be unenforceable or invalid or
  shall cease for any reason to be in full force and effect or any
  Guarantor, or any Person acting on behalf of any Guarantor, shall deny or
  disaffirm its obligations under its Subsidiary Guarantee.

However, a default under clauses (4) or (5) will not constitute an Event of
Default until the trustee or the holders of 25% in principal amount of the
outstanding notes notify Airgas of the default and Airgas does not cure such
default within the time specified after receipt of such notice. In the case of

                                       45


an Event of Default arising from certain events of bankruptcy or insolvency
with respect to Airgas, all outstanding notes will become due and payable
immediately without further action or notice. If any other Event of Default
occurs and is continuing, the trustee or the Holders of at least 25% in
principal amount of the then outstanding notes may declare all the notes to be
due and payable immediately.

    Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture. Subject to certain limitations, Holders of a
majority in principal amount of the then outstanding notes may direct the
trustee in its exercise of any trust or power. The trustee may withhold from
Holders of the notes notice of any continuing Default if it determines that
withholding notes is in their interest, except a Default relating to the
payment of principal or interest or Special Interest.

    The Holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the trustee may on behalf of the Holders of all of the
notes waive any existing Default and its consequences under the indenture
except a continuing Default in the payment of interest or Special Interest on,
or the principal of, the notes (other than the non-payment of principal of or
interest or Special Interest, if any, on the notes that became due solely
because of the acceleration of the notes).

    Airgas is required to deliver to the trustee within 90 days after the end
of each fiscal year a statement regarding compliance with the indenture during
such fiscal year. Upon becoming aware of any Default, Airgas is required to
deliver to the trustee a statement specifying such Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

    No director, officer, employee, incorporator or stockholder of Airgas or
any Guarantor, as such, will have any liability for any obligations of Airgas
or the Guarantors under the notes, the indenture, the Subsidiary Guarantees, or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of notes by accepting a note waives and releases
all such liability. The waiver and release are part of the consideration for
issuance of the notes. The waiver may not be effective to waive liabilities
under the federal securities laws, and it is the view of the Commission that
such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

    Airgas may, at its option and at any time, elect to terminate all of the
obligations of itself and the Guarantors with respect to the notes and the
indenture ("Legal Defeasance") except for:

      (1) the rights of Holders to receive payments in respect of the
  principal of, or interest or premium or Special Interest, if any, on such
  notes when such payments are due from the Defeasance Trust (as defined
  below);

      (2) Airgas' obligations to issue temporary notes, register the
  transfer or exchange of notes, to replace mutilated, destroyed, lost or
  stolen notes and to maintain a registrar and paying agent in respect of
  the notes;

      (3) the rights, powers, trusts, duties and immunities of the trustee,
  and Airgas' and the Guarantors' obligations in connection therewith; and

      (4) the Legal Defeasance provisions of the indenture.

    In addition, Airgas may, at its option and at any time, elect to have the
obligations of Airgas and the Guarantors released with respect to certain
covenants that are described in the indenture ("Covenant Defeasance") and
thereafter any omission to comply with those covenants will not constitute a
Default with respect to the notes. In the event Covenant Defeasance occurs,
certain

                                       46


events (not including non-payment or bankruptcy, receivership, rehabilitation
and insolvency events with respect to Airgas) described under "Events of
Default and Remedies" will no longer constitute an Event of Default with
respect to the notes.

    If Airgas exercises its Legal Defeasance option or its Covenant Defeasance
option, each Guarantor will be released from all of its obligations with
respect to its Guarantee.

    In order to exercise either Legal Defeasance or Covenant Defeasance:

      (1) Airgas must irrevocably deposit with the trustee, in trust (the
  "Defeasance Trust"), for the benefit of the Holders of the notes, cash in
  U.S. dollars, non-callable Government Securities, or a combination of cash
  in U.S. dollars and non-callable Government Securities, in amounts as will
  be sufficient, in the opinion of a nationally recognized firm of
  independent public accountants, to pay the principal of, or interest and
  premium and Special Interest, if any, on the outstanding notes on the
  stated maturity or on the applicable redemption date, as the case may be,
  and Airgas must specify whether the notes are being defeased to maturity
  or to a particular redemption date;

      (2) in the case of Legal Defeasance, Airgas has delivered to the
  trustee an opinion of counsel reasonably acceptable to the trustee
  confirming that (a) Airgas has received from, or there has been published
  by, the Internal Revenue Service a ruling or (b) since the date of the
  indenture, there has been a change in the applicable federal income tax
  law, in either case to the effect that, and based thereon such opinion of
  counsel will confirm that, the Holders of the outstanding notes will not
  recognize income, gain or loss for federal income tax purposes as a result
  of such Legal Defeasance and will be subject to federal income tax on the
  same amounts, in the same manner and at the same times as would have been
  the case if such Legal Defeasance had not occurred;

      (3) in the case of Covenant Defeasance, Airgas has delivered to the
  trustee an opinion of counsel reasonably acceptable to the trustee
  confirming that the Holders of the outstanding notes will not recognize
  income, gain or loss for federal income tax purposes as a result of such
  Covenant Defeasance and will be subject to federal income tax on the same
  amounts, in the same manner and at the same times as would have been the
  case if such Covenant Defeasance had not occurred;

      (4) no Default has occurred and is continuing on the date of such
  deposit (other than a Default resulting from the borrowing of funds to be
  applied to such deposit);

      (5) such Legal Defeasance or Covenant Defeasance will not result in a
  breach or violation of, or constitute a default under any material
  agreement or instrument (other than the indenture) to which Airgas or any
  of its Restricted Subsidiaries is a party or by which Airgas or any of its
  Restricted Subsidiaries is bound, including the New Credit Facility;

      (6) Airgas must deliver to the trustee an officers' certificate
  stating that the deposit was not made by Airgas with the intent of
  preferring the Holders of notes over the other creditors of Airgas with
  the intent of defeating, hindering, delaying or defrauding other creditors
  of Airgas; and

      (7) Airgas must deliver to the trustee an officers' certificate and an
  opinion of counsel, each stating that all conditions precedent relating to
  the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

    Except as provided in the next three succeeding paragraphs, the indenture
or the notes may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount

                                       47


of the notes then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, notes), and any existing default or compliance with any provision of the
indenture or the notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding notes (including, without
limitation, consents obtained in connection with a purchase of, or tender
offer or exchange offer for, notes).

    Without the consent of each Holder affected, an amendment or waiver may
not (with respect to any notes held by a non-consenting Holder):

      (1) reduce the principal amount of notes whose Holders must consent to
  an amendment, supplement or waiver;

      (2) reduce the principal of or change the fixed maturity of any note
  or alter the provisions with respect to the redemption of the notes;

      (3) reduce the rate of or change the time for payment of interest on
  any note;

      (4) waive a Default in the payment of principal of, or interest or
  premium or Special Interest, if any, on the notes (except a rescission of
  acceleration of the notes by the Holders of at least a majority in
  aggregate principal amount of the notes and a waiver of the payment
  default that resulted from such acceleration);

      (5) make any note payable in money other than that stated in the
  notes;

      (6) make any change in the provisions of the indenture relating to
  waivers of past Defaults or the rights of Holders of notes to receive
  payments of principal of, or interest or premium or Special Interest, if
  any, on the notes;

      (7) waive a redemption payment with respect to any note;

      (8) release any Guarantor from any of its obligations under its
  Subsidiary Guarantee or the indenture, except in accordance with the terms
  of the indenture; or

      (9) make any change in the preceding amendment and waiver provisions.

    In addition, any amendment to, or waiver of, the provisions of the
indenture relating to subordination that adversely affects the rights of the
Holders of the notes will require the consent of the Holders of at least 75%
in aggregate principal amount of notes then outstanding.

    Notwithstanding the foregoing, without the consent of any Holder of notes,
Airgas, the Guarantors and the trustee may amend or supplement the indenture
or the notes:

      (1) to cure any ambiguity, defect or inconsistency or to make a
  modification of a formal, minor or technical nature or to correct a
  manifest error;

      (2) to provide for uncertificated notes in addition to or in place of
  certificated notes;

      (3) to comply with the covenant relating to mergers, consolidations
  and sales of assets;

      (4) to provide for the assumption of Airgas' or any Guarantor's
  obligations to Holders of notes in the case of a merger or consolidation
  or sale of all or substantially all of Airgas' assets;

      (5) to add Guarantees with respect to the notes or to secure the
  notes;

      (6) to add to the covenants of Airgas or any Guarantor for the benefit
  of the Holders of the notes or surrender any right or power conferred upon
  Airgas or any Guarantor;

      (7) to make any change that would provide any additional rights or
  benefits to the Holders of notes or that does not adversely affect the
  legal rights under the indenture of any such Holder;


                                      48


      (8) to comply with any requirement of the Commission in connection
  with the qualification of the indenture under the Trust indenture Act;

      (9) to evidence and provide for the acceptance and appointment under
  the indenture of a successor trustee pursuant to the requirements thereof;
  or

      (10) to provide for the issuance of exchange or private exchange
  notes.

    However, no amendment may be made to (A) the subordination provisions of
the indenture or (B) the conditions precedent to Legal Defeasance and Covenant
Defeasance described in clause (5) under the caption "--Legal Defeasance and
Covenant Defeasance," in each case, that adversely affects the rights of any
holder of Senior Debt of Airgas or a Guarantor then outstanding unless the
holders of such Senior Debt (or their representative) consents to such change.

    The consent of the Holders is not necessary under the indenture to approve
the particular form of any proposed amendment. It is sufficient if such consent
approves the substance of the proposed amendment.

    The provisions under the indenture relating to Airgas' obligation to make
an offer to repurchase the notes as described above under the caption "--
Repurchase at the Option of Holders" may be waived or modified with the written
consent of the Holders of a majority in principal amount of the notes then
outstanding.

    After an amendment under the indenture becomes effective, we are required
to mail to holders of the notes a notice briefly describing such amendment.
However, the failure to give such notice to all holders of the notes, or any
defect therein, will not impair or affect the validity of the amendment.

Satisfaction and Discharge

    The indenture will be discharged and will cease to be of further effect as
to all notes issued thereunder, when:

      (1) either:

         (a) all notes that have been authenticated, except lost, stolen or
     destroyed notes that have been replaced or paid and notes for whose
     payment money has been deposited in trust and thereafter repaid to
     Airgas, have been delivered to the trustee for cancellation; or

         (b) all notes that have not been delivered to the trustee for
     cancellation have become due and payable by reason of the mailing of a
     notice of redemption or otherwise or will become due and payable
     within one year and Airgas or any Guarantor has irrevocably deposited
     or caused to be deposited with the trustee as trust funds in trust
     solely for the benefit of the Holders, cash in U.S. dollars, non-
     callable Government Securities, or a combination of cash in U.S.
     dollars and non-callable Government Securities, in amounts as will be
     sufficient without consideration of any reinvestment of interest, to
     pay and discharge the entire indebtedness on the notes not delivered
     to the trustee for cancellation for principal, premium or Special
     Interest, if any, and accrued interest to the date of maturity or
     redemption;

      (2) no Default has occurred and is continuing on the date of the
  deposit or will occur as a result of the deposit and the deposit will not
  result in a breach or violation of, or constitute a default under, any
  other instrument to which Airgas or any Guarantor is a party or by which
  Airgas or any Guarantor is bound;

      (3) Airgas or any Guarantor has paid or caused to be paid all sums
  payable by it under the indenture; and

                                       49


      (4) Airgas has delivered irrevocable instructions to the trustee under
  the indenture to apply the deposited money toward the payment of the notes
  at maturity or the redemption date, as the case may be.

    In addition, Airgas must deliver an officers' certificate and an opinion of
counsel to the trustee stating that all conditions precedent to satisfaction
and discharge have been satisfied.

Concerning the Trustee

    If the trustee becomes a creditor of Airgas or any Guarantor, the indenture
limits its right to obtain payment of claims in certain cases, or to realize on
certain property received in respect of any such claim as security or
otherwise. The trustee will be permitted to engage in other transactions;
however, if it acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the Commission for permission to continue or
resign.

    The Holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. The indenture provides that in case an Event of Default
occurs and is continuing, the trustee will be required, in the exercise of its
power, to use the degree of care of a prudent man in the conduct of his own
affairs. Subject to such provisions, the trustee will be under no obligation to
exercise any of its rights or powers under the indenture at the request of any
Holder of notes, unless such Holder has offered to the trustee security and
indemnity satisfactory to it against any loss, liability or expense.

indenture and registration rights agreement without charge by writing to

Relations.

Book-Entry, Delivery and Form

    The new notes will be represented by one or more notes in registered,
global form without interest coupons (collectively, the "Global Notes"). The
Global Notes will be deposited upon issuance with the trustee as custodian for
DTC, in New York, New York, and registered in the name of DTC or its nominee,
in each case for credit to an account of a direct or indirect participant in
DTC as described below.

    Except as set forth below, the Global Notes may be transferred, in whole
and not in part, only to another nominee of DTC or to a successor of DTC or its
nominee. Beneficial interests in the Global Notes may not be exchanged for
notes in certificated form except in the limited circumstances described below.
See "--Exchange of Book-Entry Notes for Certificated Notes." Except in the
limited circumstances described below, owners of beneficial interests in the
Global Notes will not be entitled to receive physical delivery of notes in
certificated form. Transfers of beneficial interests in the Global Notes will
be subject to the applicable rules and procedures of DTC and its direct or
indirect participants, which may change from time to time.

Depository Procedures

    The following description of the operations and procedures of DTC is
provided solely as a matter of convenience. These operations and procedures are
solely within the control of DTC and are subject to changes by DTC. Airgas
takes no responsibility for these operations and procedures and urges investors
to contact DTC directly to discuss these matters.

                                       50


    DTC has advised Airgas that DTC is a limited-purpose trust company created
to hold securities for its participating organizations (collectively, the
"Participants") and to facilitate the clearance and settlement of transactions
in those securities between Participants through electronic book-entry changes
in accounts of its Participants. The Participants include securities brokers
and dealers (including the initial purchasers), banks, trust companies,
clearing corporations and certain other organizations. Access to DTC's system
is also available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly (collectively, the "Indirect
Participants"). Persons who are not Participants may beneficially own
securities held by or on behalf of DTC only through the Participants or the
Indirect Participants. The ownership interests in, and transfers of ownership
interests in, each security held by or on behalf of DTC are recorded on the
records of the Participants and Indirect Participants.

    DTC has also advised Airgas that, pursuant to procedures established by it:

      (1) upon deposit of the Global Notes, DTC will credit the accounts of
  Participants designated by the initial purchasers with portions of the
  principal amount of the Global Notes; and
      (2) ownership of these interests in the Global Notes will be shown on,
  and the transfer of ownership of these interests will be effected only
  through, records maintained by DTC (with respect to the Participants) or
  by the Participants and the Indirect Participants (with respect to other
  owners of beneficial interest in the Global Notes).

    The laws of some states require that certain Persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a Global Note to such Persons will be limited
to that extent. Because DTC can act only on behalf of Participants, which in
turn act on behalf of Indirect Participants, the ability of a Person having
beneficial interests in a Global Note to pledge such interests to Persons that
do not participate in the DTC system, or otherwise take actions in respect of
such interests, may be affected by the lack of a physical certificate
evidencing such interests.

    Except as described below, owners of interests in the Global Notes will not
have notes registered in their names, will not receive physical delivery of
notes in certificated form and will not be considered the registered owners or
"Holders" thereof under the indenture for any purpose.

    Payments in respect of the principal of, and interest and premium and
Special Interest, if any, on a Global Note registered in the name of DTC or its
nominee will be payable to DTC in its capacity as the registered Holder under
the indenture. Under the terms of the indenture, Airgas and the trustee will
treat the Persons in whose names the notes, including the Global Notes, are
registered as the owners of the notes for the purpose of receiving payments and
for all other purposes. Consequently, neither Airgas, the trustee nor any agent
of Airgas or the trustee has or will have any responsibility or liability for:

      (1) any aspect of DTC's records or any Participant's or Indirect
  Participant's records relating to or payments made on account of
  beneficial ownership interest in the Global Notes or for maintaining,
  supervising or reviewing any of DTC's records or any Participant's or
  Indirect Participant's records relating to the beneficial ownership
  interests in the Global Notes; or

      (2) any other matter relating to the actions and practices of DTC or
  any of its Participants or Indirect Participants.

    DTC has advised Airgas that its current practice, upon receipt of any
payment in respect of securities such as the notes (including principal and
interest), is to credit the accounts of the relevant

                                       51


Participants with the payment on the payment date unless DTC has reason to
believe it will not receive payment on such payment date. Each relevant
Participant is credited with an amount proportionate to its beneficial
ownership of an interest in the principal amount of the relevant security as
shown on the records of DTC. Payments by the Participants and the Indirect
Participants to the beneficial owners of notes will be governed by standing
instructions and customary practices and will be the responsibility of the
Participants or the Indirect Participants and will not be the responsibility of
DTC, the trustee or Airgas. Neither Airgas nor the trustee will be liable for
any delay by DTC or any of its Participants in identifying the beneficial
owners of the notes, and Airgas and the trustee may conclusively rely on and
will be protected in relying on instructions from DTC or its nominee for all
purposes.

    DTC has advised Airgas that it will take any action permitted to be taken
by a Holder of notes only at the direction of one or more Participants to whose
account DTC has credited the interests in the Global Notes and only in respect
of such portion of the aggregate principal amount of the notes as to which such
Participant or Participants has or have given such direction. However, if there
is an Event of Default under the notes, DTC reserves the right to exchange the
Global Notes for legended notes in certificated form, and to distribute such
notes to its Participants.

    Although DTC has agreed to the foregoing procedures to facilitate transfers
of interests in the Global Notes among participants in DTC, they are under no
obligation to perform or to continue to perform such procedures, and may
discontinue such procedures at any time. Neither Airgas nor the trustee nor any
of their respective agents will have any responsibility for the performance by
DTC or its participants or indirect participants of its obligations under the
rules and procedures governing its operations.

Exchange of Global Notes for Certificated Notes

    A Global Note is exchangeable for definitive notes in registered
certificated form ("Certificated Notes") if:

      (1) DTC (a) notifies Airgas that it is unwilling or unable to continue
  as depositary for the Global Notes and Airgas fails to appoint a successor
  depositary or (b) has ceased to be a clearing agency registered under the
  Exchange Act and Airgas fails to appoint a successor depositary;

      (2) Airgas, at its option, notifies the trustee in writing that it
  elects to cause the issuance of the Certificated Notes; or

      (3) there has occurred and is continuing a Default with respect to the
  notes.

In addition, beneficial interests in a Global Note may be exchanged for
Certificated Notes upon prior written notice given to the trustee by or on
behalf of DTC in accordance with the indenture. In all cases, Certificated
Notes delivered in exchange for any Global Note or beneficial interests in
Global Notes will be registered in the names, and issued in any approved
denominations, requested by or on behalf of the depositary (in accordance with
its customary procedures).

Exchange of Certificated Notes for Global Notes

    Certificated Notes may not be exchanged for beneficial interests in any
Global Note unless the transferor first delivers to the trustee a written
certificate (in the form provided in the indenture) to the effect that such
transfer will comply with the appropriate transfer restrictions applicable to
such notes.


                                       52


Same Day Settlement and Payment

    Airgas will make payments in respect of the notes represented by the Global
Notes (including principal, premium, if any, interest and Special Interest, if
any) by wire transfer of immediately available funds to the accounts specified
by the Global Note Holder. Airgas will make all payments of principal, interest
and premium and Special Interest, if any, with respect to Certificated Notes by
wire transfer of immediately available funds to the accounts specified by the
Holders of the Certificated Notes or, if no such account is specified, by
mailing a check to each such Holder's registered address. The notes represented
by the Global Notes are expected to be eligible to trade in the PORTAL market
and to trade in DTC's Same-Day Funds Settlement System, and any permitted
secondary market trading activity in such notes will, therefore, be required by
DTC to be settled in immediately available funds. Airgas expects that secondary
trading in any Certificated Notes will also be settled in immediately available
funds.

Registration Rights; Special Interest

    Holders of the new notes are not entitled to any registration rights with
respect to the new notes.

    The following description is a summary of the material provisions of the
registration rights agreement. It does not restate that agreement in its
entirety. We urge you to read the proposed form of registration rights
agreement in its entirety because it, and not this description, defines the
registration rights of Holders of old notes. See "--Additional Information."

    Airgas, the Guarantors and the initial purchasers entered into the
registration rights agreement on the closing of the offering of old notes.
Pursuant to the registration rights agreement, Airgas and the Guarantors agreed
to file with the Commission the exchange offer registration statement on the
appropriate form under the Securities Act with respect to the notes. Upon the
effectiveness of the exchange offer registration statement, Airgas and the
Guarantors will offer to the Holders of Transfer Restricted Securities pursuant
to the exchange offer who are able to make certain representations the
opportunity to exchange their Transfer Restricted Securities for new notes.

    If:

      (1) Airgas and the Guarantors are not

         (a) required to file the exchange offer registration statement; or

         (b) permitted to consummate the exchange offer because the
     exchange offer is not permitted by applicable law or Commission
     policy; or

      (2) any Holder of Transfer Restricted Securities notifies Airgas prior
  to the 20th day following consummation of the exchange offer that:

         (a) it is prohibited by law or Commission policy from
     participating in the exchange offer; or

         (b) that it may not resell the new notes acquired by it in the
     exchange offer to the public without delivering a prospectus and the
     prospectus contained in the exchange offer registration statement is
     not appropriate or available for such resales; or

         (c) that it is a broker-dealer and owns old notes acquired
     directly from Airgas or an affiliate of Airgas,


                                       53


Airgas and the Guarantors will file with the Commission a shelf registration
statement to cover resales of the old notes by the Holders of the old notes who
satisfy certain conditions relating to the provision of information in
connection with the shelf registration statement.

    Airgas and the Guarantors will use their reasonable best efforts to cause
the applicable registration statement to be declared effective as promptly as
possible by the Commission.

    For purposes of the preceding, "Transfer Restricted Securities" means each
old note until:

      (1) the date on which such note has been exchanged by a Person other
  than a broker-dealer for an Exchange Note in the Exchange Offer;

      (2) following the exchange by a broker-dealer in the exchange offer of
  an old note for a new note, the date on which such new note is sold to a
  purchaser who receives from such broker-dealer on or prior to the date of
  such sale a copy of the prospectus contained in the exchange offer
  registration statement;

      (3) the date on which such note has been effectively registered under
  the Securities Act and disposed of in accordance with the shelf
  registration statement; or

      (4) the date on which such note is distributed to the public pursuant
  to Rule 144 under the Securities Act.

    The registration rights agreement provides that:

      (1) Airgas and the Guarantors will file an exchange offer registration
  statement with the Commission on or prior to 90 days after the closing of
  the offering of old notes;

      (2) Airgas and the Guarantors will use their reasonable best efforts
  to have the exchange offer registration statement declared effective by
  the Commission on or prior to 180 days after the closing of this offering
  of old notes;

      (3) unless the exchange offer would not be permitted by applicable law
  or Commission policy, Airgas and the Guarantors will

         (a) commence the exchange offer; and

         (b) use their reasonable best efforts to issue on or prior to 30
     business days, or longer, if required by the federal securities laws,
     after the date on which the exchange offer registration statement was
     declared effective by the Commission, new notes in exchange for all
     old notes tendered prior thereto in the exchange offer; and

      (4) if obligated to file the shelf registration statement, Airgas and
  the Guarantors will use their reasonable best efforts to file the shelf
  registration statement with the Commission on or prior to 60 days after
  such filing obligation arises and to cause the shelf registration
  statement to be declared effective by the Commission on or prior to 120
  days after such obligation arises or such later dates on which the
  exchange offer registration statement would have been required to be filed
  or declared effective, as the case may be.

    If:

      (1) Airgas and the Guarantors fail to file any of the registration
  statements required by the registration rights agreement on or before the
  date specified for such filing; or

      (2) any of such registration statements is not declared effective by
  the Commission on or prior to the date specified for such effectiveness
  (the "Effectiveness Target Date"); or

      (3) Airgas and the Guarantors fail to consummate the exchange offer
  within 30 business days of the Effectiveness Target Date with respect to
  the exchange offer registration statement; or

                                       54


      (4) the shelf registration statement or the exchange offer
  registration statement is declared effective but thereafter ceases to be
  effective or usable in connection with resales of Transfer Restricted
  Securities during the periods specified in the registration rights
  agreement (each such event referred to in clauses (1) through (4) above, a
  "Registration Default"),

then Airgas and the Guarantors will pay Special Interest to each Holder of
notes, with respect to the first 90-day period immediately following the
occurrence of the first Registration Default in an amount equal to 0.25% per
annum of the principal amount of notes held by such Holder.

    The amount of the Special Interest will increase by an additional 0.25% per
annum of the principal amount of notes with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum amount
of Special Interest for all Registration Defaults of 1.0% per annum of the
principal amount of notes.

    All accrued Special Interest will be paid by Airgas and the Guarantors on
each Damages Payment Date to the Global Note Holder by wire transfer of
immediately available funds or by federal funds check and to Holders of
Certificated Notes by wire transfer to the accounts specified by them or by
mailing checks to their registered addresses if no such accounts have been
specified.

    Following the cure of all Registration Defaults, the accrual of Special
Interest will cease.

    Holders of old notes will be required to make certain representations to
Airgas (as described in the registration rights agreement) in order to
participate in the exchange offer and will be required to deliver certain
information to be used in connection with the shelf registration statement and
to provide comments on the shelf registration statement within the time periods
set forth in the registration rights agreement in order to have their notes
included in the shelf registration statement and benefit from the provisions
regarding Special Interest set forth above. By acquiring Transfer Restricted
Securities, a Holder will be deemed to have agreed to indemnify Airgas and the
Guarantors against certain losses arising out of information furnished by such
Holder in writing for inclusion in any shelf registration statement. Holders of
notes will also be required to suspend their use of the prospectus included in
any registration statement under certain circumstances upon receipt of written
notice to that effect from Airgas.

Certain Definitions

subsequent to the commencement of the period for which the Fixed Charge
Coverage Ratio is being calculated and on or prior to the date on which the
event for which the calculation of the Fixed Charge Coverage Ratio is made (the

  of prior to the Calculation Date, will be excluded, but only to the extent
  that the obligations giving rise to such Fixed Charges will not be
  obligations of the specified Person or any of its Subsidiaries following
  the Calculation Date.

    For purposes of this definition, whenever pro forma effect is to be given
to an acquisition of assets, the amount of income or earnings relating thereto

faith by a responsible financial or accounting officer of Airgas. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness shall be calculated as if the rate in

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following discussion is a general summary of certain U.S. Federal
income tax consequences of the exchange offer to holders of old notes. The
summary below is based upon the Internal Revenue Code of 1986, as amended (the
"Code"), regulations of the Treasury Department, administrative rulings and
pronouncements of the Internal Revenue Service and judicial decisions, all of
which are subject to change, possibly with retroactive effect. This summary
does not address all of the U.S. Federal income tax consequences that may be
applicable to particular holders, including dealers in securities, financial
institutions, insurance companies and tax-exempt organizations. In addition,
this summary does not consider the effect of any foreign, state, local, gift,
estate or other tax laws that may be applicable to a particular holder. This
summary applies only to a holder that acquired old notes at original issue for
cash and holds such old notes as a capital asset within the meaning of Section
1221 of the Code. Holders of old notes considering the exchange offer should
consult their own tax advisors concerning the U.S. Federal income tax
consequences in light of their particular situations as well as any
consequences arising under the laws of any other taxing jurisdiction.

    An exchange of old notes for new notes pursuant to the exchange offer will
not be treated as a taxable exchange or other taxable event for U.S. Federal
income tax purposes. Accordingly, there will be no U.S. Federal income tax
consequences to holders who exchange their old notes for new notes in
connection with the exchange offer and any such holder will have the same
adjusted tax basis and holding period in the new notes as it had in the old
notes immediately before the exchange.

                                       72


                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver a prospectus in
connection with nay resale of such new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new notes received in exchange for old notes where
such old notes were acquired as a result of market-making activities or other
trading activities. The Company has agreed that, for a period of 120 days after
the expiration date, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until         , 2001, all dealers effecting transactions in the new
notes may be required to deliver a prospectus.


    We will not receive any proceeds from any sale of new notes by broker-
dealers. New notes received by broker-dealers for their own account pursuant to
the exchange offer may be sold from time to time in one or more transactions in
the over-the-counter market, in negotiated transactions, through the writing of
options on the new notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer or the
purchasers of any such new notes. Any broker-dealer that resells new notes that
were received by it for its own account pursuant to the exchange offer and any
broker or dealer that participates in a distribution of such new notes may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of new notes and any commission or concessions
received by any such persons may be deemed to be underwriting compensation
under the Securities Act. The letter of transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

    For a period of 120 days after the expiration date we will promptly send

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers

    The following registrants are corporations incorporated in the state of
Delaware: Airgas, Inc., Airgas-East, Inc., Airgas-Great Lakes, Inc., Airgas-Mid
America, Inc., Airgas-North Central, Inc., Airgas-South, Inc., Airgas-Gulf
States, Inc., Airgas-Mid South, Inc., Airgas-Nor Pac, Inc., Airgas-Northern
California & Nevada, Inc., Airgas-Southwest, Inc., Airgas-Safety, Inc., Airgas
Carbonic, Inc., Nitrous Oxide Corp., Puritan Medical Products, Inc., ATNL,
Inc., Airgas Realty, Inc., and Cylinder Leasing Corp. Section 145(a) of the
Delaware General Corporation Law (the "DGCL") provides in relevant part that a
corporation may indemnify any officer or director who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
director or officer of another entity, 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 interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe such person's conduct was unlawful. Under Section 145(b) of the DGCL,
such eligibility for indemnification may be further subject to the adjudication
of the Delaware Court of Chancery.

    The articles of incorporation and/or by-laws of each of the Delaware
corporation registrants provide that such registrant indemnifies its officers
and directors to the maximum extent allowed by Delaware law.

    Furthermore, Section 102(b)(7) of the DGCL provides that a corporation may
in its certificate of incorporation eliminate or limit the personal liability
of a director to the corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director except for liability: for any breach of
the director's duty of loyalty to the corporation or its stockholders; for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; under Section 174 of the DGCL (pertaining to certain
prohibited acts including unlawful payment of dividends or unlawful purchase or
redemption of the corporation's capital stock); or for any transaction from
which the director derived an improper personal benefit. The following Delaware
corporation registrants eliminate such personal liability of their directors:
Airgas, Inc., Airgas-East, Inc., Airgas-Mid America, Inc., Airgas-North
Central, Inc., Airgas-Gulf States, Inc., Airgas-Mid South, Inc., Airgas-Nor
Pac, Inc., Airgas-Northern California & Nevada, Inc., Airgas-Southwest, Inc.,

    The following registrants are limited liability companies formed in the
state of Delaware: Airgas Data, LLC and Airgas Direct Industrial Vessel, LLC.

subject to such standards and restrictions, if any, as are set forth in its
limited liability company agreement, a limited liability company may, and shall
have the power to, indemnify and hold harmless any member or manager or other
person from and against any and all claims and demands whatsoever.

    Section 5.4 of each of the limited liability company agreements of Airgas
Data, LLC and of Airgas Direct Industrial Vessel, LLC provides that a member's
liability shall be limited to the aggregate amount of the capital contributions
made or is otherwise legally obligated to be made in accordance with the
provisions of the respective agreements. Section 8.1 of each of the limited
liability company agreements of Airgas Data, LLC and of Airgas Direct
Industrial Vessel, LLC provide

                                      II-1


that each may indemnify any person who was or is a party defendant or is
threatened to be made a party defendant to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative, or
investigation (other than an action by or in the right of the applicable
company) by reason of the fact that such person is or was a member, manager,
officer, employee or agent of such company, or is or was serving at the request
of such company, against expenses (including reasonable 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
the manager (except if the manager is seeking indemnification, in which case,
the member or members, as the case may be) determines that said 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 applicable company, and, with respect to
any criminal action or proceeding, said person had no reasonable cause to
believe the conduct was unlawful.

    The following registrants are corporations incorporated in the state of
California: Airgas-West, Inc. and Rutland Tool & Supply Co., Inc. Section 204
of the California Corporations Code provides that a corporation may set forth

personal liability of a director for monetary damages in an action brought by

Corporations Code, so long as such indemnification is subject to certain
limitations and conditions as provided therein and (ii) authorizing, whether by
bylaw, agreement or otherwise, the indemnification of agents (as defined in
Section 317 of the California Corporations Code) in excess of that expressly
permitted by Section 317 for those agents of the corporation for breach of duty
to the corporation and its stockholders, so long as such indemnification is
subject to certain limitations and conditions as provided therein.

    Section 317 of the California Corporations Code provides that a corporation
shall have to power to indemnify any person who was or is a party or is
threatened to be made a party to any proceeding (other than an action by or in
the right of the corporation to procure a judgment in its favor) by reason of
the fact that the person is or was an agent of the corporation, against
expenses, judgments, fines, settlements, and other amounts actually and
reasonably incurred in connection with the proceeding if that person acted in
good faith and in a manner the person reasonably believed to be in the best
interests of the corporation and, in the case of a criminal proceeding, had no
reasonable cause to believe the conduct of the person was unlawful. This
section also provides that a corporation shall have to power to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action by or in the right of the corporation
to procure a judgment in its favor by reason of the fact that the person is or
was an agent of the corporation, against expenses actually and reasonably
incurred by that person in connection with the defense or settlement of the
action if that person acted in good faith, in a manner the person believed to
be in the best interests of the corporation and its shareholders, where such
indemnification is subject to certain limitations and conditions as provided
therein.

director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys'
fees, judgments, fines and amounts paid in settlement actually and reasonably

Item 22. Undertakings

    Airgas, Inc. hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of Airgas, Inc.'s
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the registration statement 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.

    The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this Form, within one business day of the receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

    The undersigned registrants hereby undertake to supply by means of 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.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrants pursuant to the provisions described in Item 20 above, or
otherwise, the registrants have 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
registrants will, unless in the opinion of counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question of 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.

                                      II-8

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

Ladies and Gentlemen:

          We have acted as counsel for Airgas, Inc., a Delaware corporation (the
"Company"), in connection with the filing by the Company with the Securities and
Exchange Commission (the "Commission") of a registration statement on Form S-4
(the "Registration Statement") under the Securities Act of 1933 (the "Act"),
relating to the proposed issuance and exchange of up to $225,000,000 aggregate
principal amount of the Company's outstanding 9.125% Senior Subordinated Notes
due 2011 (the "Old Notes") for a like principal amount of the Company's 9.125%
Senior Subordinated Notes due 2011 (the "New Notes").  The New Notes are to be
issued pursuant to the indenture dated as of July 30, 2001 (the "Indenture"),
among the Company, the Company's subsidiaries listed on Schedule I thereto (the
"Guarantors") and The Bank of New York, as trustee (the "Trustee").

          In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for purposes of
this opinion, including the Indenture.

          Based on the foregoing, we are of opinion as follows:

          1.  The Indenture has been duly authorized, executed and delivered by
the Company and by each of the Guarantors listed on Schedule A hereto (the
"Delaware Guarantors").  The Indenture constitutes a legal, valid and


                                                                               2


binding obligation of the Company and each Guarantor, enforceable against the
Company and each Guarantor in accordance with its terms (subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other
similar laws affecting creditors' rights generally from time to time in effect
and to general principles of equity, including concepts of materiality,
reasonableness, good faith and fair dealing, regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          2.  The New Notes have been duly authorized by the Company and when
executed, issued and authenticated in accordance with the provisions of the
Indenture and delivered in exchange for the Old Notes, will constitute legal,
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms and entitled to the benefits of the Indenture
(subject to applicable bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium or other similar laws affecting creditors' rights
generally from time to time in effect and subject, as to enforceability, to
general principles of equity, regardless of whether such enforceability is
considered in a proceeding in equity or at law).

          3.  The guarantees to be endorsed on the New Notes by each Delaware
Guarantor have been duly authorized by such Delaware Guarantor.  When the New
Notes have been executed, issued and authenticated in accordance with the
provisions of the Indenture and delivered in exchange for the Old Notes, the
guarantees to be endorsed on the New Notes will constitute legal, valid and
binding obligations of the Guarantors, enforceable against each Guarantor in
accordance with their terms (subject to applicable bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium or other similar laws affecting
creditors' rights generally from time to time in effect and subject, as to
enforceability, to general principles of equity, regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          In expressing the opinion set forth in paragraphs 1, 2 and 3 above, we
have assumed, with your consent, that:  (i) the Indenture has been duly
authorized, executed and delivered by the parties thereto (other than the
Delaware Guarantors); (ii) the form of the New Notes and of the guarantees to be
endorsed thereon will each conform to that included in the Indenture; and (iii)
the guarantees to be endorsed on the New Notes have been duly authorized by the
Guarantors (other than the Delaware Guarantors).


                                                                               3



          We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement.  We also consent to the reference to
our firm under the caption "Legal Matters" in the Registration Statement.  In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

          We are admitted to practice in the State of New York and we do not
express any opinion with respect to matters governed by any laws other than the
laws of the State of New York, the General Corporation Law of the State of
Delaware and the federal laws of the United States of America.

          We are furnishing this opinion to you, solely for your benefit.  This
opinion may not be relied upon by any other person or for any other purpose or
used, circulated, quoted or otherwise referred to for any other purpose.


                                             Very truly yours,

          Subordinated Notes due 2011
          -----------------------------------------------------------

Ladies and Gentlemen:

     Solely for the purpose of rendering this opinion, we have acted as special
California counsel to Airgas-West, Inc. and Rutland Tool & Supply Co., Inc.,
each a California corporation (the "California Guarantors") and each a
subsidiary of Airgas, Inc., a Delaware corporation (the "Company"), in
connection with the proposed issuance and exchange (the "Exchange Offer") of up
to $225,000,000 aggregate principal amount of the Company's outstanding 9.125%
Senior Subordinated Notes due 2011 (the "Old Notes") for a like principal amount
of the Company's 9.125% Senior Subordinated Notes due 2011 (the "New Notes") to
be registered under the Securities Act of 1933 (the "Act").  The New Notes are
to be issued pursuant to the indenture dated as of July 30, 2001 (the
"Indenture"), among the Company, the Company's subsidiaries listed on Schedule I
thereto (the "Guarantors") and The Bank of New York, as trustee (the "Trustee").

     In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for purposes of
this opinion, including the Indenture.

     For the purpose of rendering this opinion, we have made and relied, without
independent inquiry, upon the following assumptions:

     (a) That the signatures on the Indenture and the Guarantee (as defined
below) are genuine, the authenticity of all documents referenced in this opinion
submitted to us as originals, and the conformity with the original documents of
all documents submitted to us as copies.

     (b) That there are no documents or other information which has not been
furnished to us which would materially alter, modify or amend the Indenture or
the Guarantee, and no events have occurred since the adoption of resolutions by
the California Guarantors with respect to the authorization, execution and
delivery of the Indenture and the Guaranty as of July 30, 2001 which would
rescind, invalidate or otherwise call into question said resolutions.

     1.  Each California Guarantor has duly authorized, executed and delivered
the Indenture.

     2.  Each California Guarantor has duly authorized the execution and
delivery of the guarantee (the "Guarantee") to be endorsed on the New Notes.

RE:  Airgas, Inc. $225,000,000 Principal Amount of 9.125% Senior Subordinated
Notes due 2011

Ladies and Gentlemen:

     Solely for the purpose of rendering this opinion, we have acted as special
Nevada counsel to Red-D-Arc Inc., a Nevada corporation (the "Nevada Guarantor"),
and subsidiary of Airgas, Inc., a Delaware corporation (the "Company"), in
connection with the proposed issuance and exchange (the "Exchange Offer") of up
to $225,000,000 aggregate principal amount of the Company's outstanding 9.125%
Senior Subordinated Notes due 2011 (the "Old Notes") for a like principal amount
of the Company's 9.125% Senior Subordinated Notes due 2011 (the "New Notes") to
be registered under the Securities Act of 1933 (the "Act").  The New Notes are
to be issued pursuant to the indenture dated as of July 30, 2001 (the
"Indenture"), among the Company, the Company's subsidiaries listed on Schedule I
thereto (the "Guarantors") and The Bank of New York, as trustee (the "Trustee").

     In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for purposes of
this opinion, including the Indenture.  We have not reviewed, and express no
opinion as to, any instrument or agreement referred to or incorporated by
reference in the Indenture.

     We have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures, the legal capacity of natural
persons and the conformity to originals of all copies of all documents submitted
to us.  We have relied upon the certificates of all public officials and
corporate officers with respect to the accuracy of all matters contained
therein.

     Based upon the foregoing, we are of the opinion that:
     1.  The Nevada Guarantor has duly authorized, executed and delivered the
Indenture.

Re:  Airgas, Inc. 9.125% Senior Subordinated Notes Due 2011

Ladies and Gentlemen:

We have acted as special Texas counsel to Airgas Speciality Gases, Inc., a Texas
corporation (the "Texas Guarantor"), solely for the purpose of rendering this
opinion in connection with the proposed issuance by Airgas, Inc. (the "Company")
of its 9.125% Senior Subordinated Notes Due 2011 (the "Notes") pursuant to the
Indenture dated as of July 30, 2001 (the "Indenture") among the Company, the
subsidiary guarantors listed on Schedule I to the Indenture and The Bank of New
York, as trustee.

In our capacity as such counsel, we have been provided with copies identified as
being true copies of, and have examined, only the following:

     1.   The Unanimous Written Consent of the Board of Directors of the Texas
          Guarantor dated July 27, 2001 (the "Board Consent").

     2.   The Articles of Incorporation of the Texas Guarantor filed with the
          Secretary of State of the State of Texas on January 27, 1986, a
          Certificate of Amendment filed in the Office of the Secretary of State
          of the State of Texas on July 31, 1989 and a Certificate of Amendment
          filed in the Office of the Secretary of State of the State of Texas on
          October 7, 1996 (collectively, the "Articles of Incorporation").

     3.   The Bylaws of the Texas Guarantor adopted on February 18, 1986 (the
          "Bylaws").

     4.   The signature page of the Indenture showing execution by the Texas
          Guarantor as a subsidiary guarantor listed on Schedule I to the
          Indenture.

In addition, we have examined and relied upon a Certificate of Existence of the
Texas Guarantor dated September 4, 2001 issued by the Secretary of State of the
State of Texas and a Certificate of Account Status dated September 4, 2001
issued by the

     b.   The person executing the Board Consent is the sole director of the
          Texas Guarantor, has legal capacity and the signature is genuine.

     c.   The copies examined by us of the Board Consent, Articles of
          Incorporation and Bylaws are true and complete copies of the originals

     RE:  Airgas, Inc. $225,000,000 Principal Amount of 9.125% Senior
          Subordinated Notes Due 2011

Ladies and Gentlemen:

     Solely for the purpose of rendering this opinion, we have acted as special
Colorado counsel to Airgas-Intermountain, Inc., a Colorado corporation (the
"Colorado Guarantor") and subsidiary of Airgas, Inc., a Delaware corporation
(the "Company"), in connection with the proposed issuance and exchange (the
"Exchange Offer") of up to $225,000,000 aggregate principal amount of the
Company's outstanding 9.125% Senior Subordinated Notes due 2011 (the "Old
Notes") for a like principal amount of the Company's 9.125% Senior Subordinated
Notes due 2011 (the "New Notes") to be registered under the Securities Act of
1933 (the "Act").  The New Notes are to be issued pursuant to the Indenture,
dated as of July 30, 2001 (the "Indenture"), among the Company, the Company's
subsidiaries listed on Schedule I thereto (the "Guarantors") and The Bank of New
York, as trustee (the "Trustee").

     In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for purposes of
this opinion, including (a) a copy of the Articles of Incorporation of the
Colorado Guarantor bearing the certification of the Colorado Secretary of State
under date of May 15, 1998, and a copy of the Bylaws and Unanimous Written
Consent of the Board of Directors of the Colorado Guarantor (the "Consent") in
the form submitted to us on behalf of the Colorado Guarantor by letter dated
August 30, 2001 (collectively, the "Colorado Corporate Records") and (b) the
Indenture.

     In rendering this opinion we have assumed the legal mental capacity of all
individuals executing the Indenture, the Guarantee, the Old Notes and the New
Notes, that each individual that executed and delivered the Indenture and the
Guarantee was at the time of such execution and delivery an "officer of the
Corporation," as that term is defined in the Consent, that the Colorado
Corporate Records are complete and correct, remain in full force and effect and
have not been amended, terminated or rescinded and that the Consent was executed
and delivered by all of the directors of the Colorado Guarantor.  We have
further assumed that the Indenture and the Guarantee (as defined below) were
issued for adequate consideration.


     Based upon the foregoing, and subject to the comments that follow we are of
the opinion that:

     The Colorado Guarantor has duly authorized, executed and delivered the
Indenture.

     The Colorado Guarantor has duly authorized the execution and delivery of
the guarantee (the "Guarantee") to be endorsed on the New Notes.

     This opinion is limited in all respects to the laws of the State of
Colorado.  We are not, and have not acted as, primary counsel to the Colorado
Guarantor in connection with the transactions or documents referred to herein.
Our participation has been limited to reviewing matters of Colorado law in
connection with the opinion expressed herein.  This opinion is as of the date
hereof and we do not undertake to advise you of changes herein which may
hereafter be brought to our attention.  This opinion is rendered solely to you
and for your benefit in connection with the above-described transactions.

     We hereby consent to the filing of this opinion with the Securities and
Exchange Commission (the "Commission") as an exhibit to the Registration
Statement on Form S-4 under the Securities Act of 1933, as amended (the "Act")
relating to the Exchange Offer.  In giving this consent, we do not hereby admit
that we are included in the category of persons whose consent is required under
Section 7 of the Act or the rules and regulations of the Commission.


                                Very truly yours,

   Delivery of this instrument to an address other than as set forth above, or
transmission of instructions via facsimile other than as set forth above, will
not constitute a valid delivery.

   The undersigned acknowledges that he or she has received the Prospectus,
dated     , 2001 (the "Prospectus"), of Airgas, Inc., a Delaware corporation
(the "Company"), and this Letter of Transmittal (the "Letter"), which together
constitute the Company's offer (the "Exchange Offer") to exchange an aggregate
principal amount of up to $225,000,000 of its 9.125% Senior Subordinated Notes
due 2011 (the "New Notes"), which have been registered under the Securities Act
of 1933, as amended (the "Securities Act") for a like principal amount at
maturity of the Company's issued and outstanding 9.125% Senior Subordinated
Notes due 2011 (the "Old Notes"). Capitalized terms used but not defined herein
shall have the same meaning given them in the Prospectus.

   For each Old Note accepted for exchange, the holder of such Old Note will
receive a New Note having a principal amount at maturity equal to that of the
surrendered Old Note. The New Notes will bear interest from the last interest
payment date of the Old Notes to occur prior to the issue date of the New Notes
or, if no interest has been paid, from the date of the governing indenture.
Interest on the New Notes will accrue at the rate of 9.125% per annum and will
be payable semiannually on each April 1 and October 1, commencing on April 1,
2002. The New Notes will mature on October 1, 2011.

   If, with respect the of Old Notes, (i) the Company is required to file a
shelf registration statement (the "Shelf Registration Statement") and has not
filed such Shelf Registration Statement on or prior to 60 days after such
filing obligation arises; or (ii) the Shelf Registration Statement has not been
declared effective on or prior to 120 days after such filing obligation arises,
or such later dates on which the Exchange Offer Registration Statement would
have been required to be filed or declared effective, as the case may be; or
(iii) the Company fails to consummate the Exchange Offer within 30 business
days of the effective date of the registration statement relating to the
Exchange Offer Registration Statement; or (iv) the Shelf Registration Statement
or Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable in connection with resales of Transfer
Restricted Securities during certain specified periods (each such event


referred to in clauses (i) through (iv) a "Registration Default"), then
commencing on the day after the occurrence of such Registration Default, the
Company will pay special interest to each holder of Transfer Restricted
Securities, with respect to the first 90-day period immediately following the
occurrence of the first Registration Default, in an amount equal to 0.25% per
annum of the principal amount at maturity of such Transfer Restricted
Securities held by such holder. The amount of the special interest will
increase by an additional 0.25% per annum of the principal amount at maturity
of such Transfer Restricted Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum amount
of special interest for all Registration Defaults of 1.0% per annum of the
principal amount at maturity of such Transfer Restricted Securities. Following
the cure of all Registration Defaults, the accrual of special interest will
cease. Holders of Old Notes accepted for exchange will be deemed to have waived
the right to receive any other payments or accrued interest on such Old Notes.

    The Company reserves the right, at any time or from time to time, to extend
the Exchange Offer at its discretion, in which event the term "Expiration Date"
shall mean the latest time and date to which the Exchange Offer is extended.
The Company shall notify the holders of the Old Notes of any extension as
promptly as practicable by oral or written notice thereof.

    This Letter is to be completed by holders of Old Notes either if
certificates are to be forwarded herewith or if a tender of Old Notes, if
available, is to be made by book-entry transfer to the account maintained by
the Exchange Agent at The Depository Trust Company (the "Book-Entry Transfer
Facility") pursuant to the procedures set forth in "The Exchange Offer" section
of the Prospectus. Holders of Old Notes whose certificates are not immediately
available, or who are unable to deliver their certificates or confirmation of
the book-entry tender of their Old Notes into the Exchange Agent's account at
the Book-Entry Transfer Facility (a "Book-Entry Confirmation") and all other
documents required by this Letter to the Exchange Agent on or prior to the
Expiration Date, must tender their Old Notes according to the guaranteed
delivery procedures set forth in "The Exchange Offer--Guaranteed Delivery
Procedures" section of the Prospectus. See Instruction 1. Delivery of documents
to the Book-Entry Transfer Facility does not constitute delivery to the
Exchange Agent.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

   Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount at
maturity of Old Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of the Old Notes tendered hereby, the undersigned
hereby sells, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to such Old Notes as are being tendered
hereby.

   The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Old Notes tendered
hereby and that the Company will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim when the same are accepted by the Company. The
undersigned hereby further represents that any New Notes acquired in exchange
for Old Notes tendered hereby will have been acquired in the ordinary course of
business of the person receiving such New Notes, whether or not such person is
the undersigned, that neither the holder of such Old Notes nor any such other
person is engaged in, or intends to engage in a distribution of such New Notes,
or has an arrangement or understanding with any person to participate in the
distribution of such New Notes, and that neither the holder of such Old Notes
nor any such other person is an "affiliate," as defined in Rule 405 under the
Securities Act, of the Company.

   The undersigned also acknowledges that this Exchange Offer is being made by
the Company based upon the Company's understanding of an interpretation by the
staff of the Securities and Exchange Commission (the "Commission") as set forth
in no-action letters issued to third parties, that the New Notes issued in
exchange for the Old Notes pursuant to the Exchange Offer may be offered for
resale, resold and otherwise transferred by holders thereof (other than any
such holder that is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that: (1) such
holders are not affiliates of the Company within the meaning of Rule 405 under
the Securities Act; (2) such New Notes are acquired in the ordinary course of
such holders' business; and (3) such holders are not engaged in, and do not
intend to engage in, a distribution of such New Notes and have no arrangement
or understanding with any person to participate in the distribution of such New
Notes. However, the staff of the Commission has not considered the Exchange
Offer in the context of a no-action letter, and there can be no assurance that
the staff of the Commission would make a similar determination with respect to
the Exchange Offer as in other circumstances. If a holder of Old Notes is an
affiliate of the Company, and is engaged in or intends to engage in a
distribution of the New Notes or has any arrangement or understanding with
respect to the distribution of the New Notes to be acquired pursuant to the
Exchange Offer, such holder could not rely on the applicable interpretations of
the staff of the Commission and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. If the undersigned is a broker-dealer that will
receive New Notes for its own account in exchange for Old Notes, it represents
that the Old Notes to be exchanged for the New Notes were acquired by it as a
result of market-making activities or other trading activities and acknowledges
that it will deliver a prospectus in connection with any resale of such New
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

   The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer--Withdrawal of Tenders"
section of the Prospectus.

1. Delivery of this Letter and Notes; Guaranteed Delivery Procedures.

    This Letter is to be completed by holders of Old Notes either if
certificates are to be forwarded herewith or if tenders are to be made pursuant
to the procedures for delivery by book-entry transfer set forth in "The
Exchange Offer--Procedures for Tendering" section of the Prospectus.
Certificates for all physically tendered Old Notes, or Book--Entry
Confirmation, as the case may be, as well as a properly completed and duly
executed Letter of Transmittal (or facsimile thereof) and any other documents
required by this Letter, must be received by the Exchange Agent at the address
set forth herein on or prior to the Expiration Date, or the tendering holder
must comply with the guaranteed delivery procedures set forth below. Old Notes
tendered hereby must be in denominations of principal amount at maturity of
$1,000 and any integral multiple thereof.

    Holders of Old Notes whose certificates for Old Notes are not immediately
available or who cannot deliver their certificates and all other required
documents to the Exchange Agent on or prior to the Expiration Date, or who
cannot complete the procedure for book-entry transfer on a timely basis, may
tender their Old Notes pursuant to the guaranteed delivery procedures set forth
in "The Exchange Offer--Guaranteed Delivery Procedures" section of the
Prospectus. Pursuant to such procedures, (i) such tender must be made through
an Eligible Institution (as defined below), (ii) prior to the Expiration Date,
the Exchange Agent must receive from such Eligible Institution a properly
completed and duly executed Letter (or facsimile thereof) and Notice of
Guaranteed Delivery, substantially in the form provided by the Company (by
facsimile transmission, mail or hand delivery), setting forth the name and
address of the holder of Old Notes, the certificate number or numbers of such
Old Notes and the principal amount at maturity of Old Notes tendered, stating
that the tender is being made thereby and guaranteeing that within five
business days after the Expiration Date, the Letter (or facsimile thereof),
together with the certificate or certificates representing the Old Notes to be
tendered in proper form for transfer, or a Book-Entry Confirmation, as the case
may be, and any other documents required by this Letter will be deposited by
the Eligible Institution with the Exchange Agent, and (iii) such properly
completed and executed Letter (or facsimile thereof), as well as the
certificate or certificates representing all tendered Old Notes in proper form
for transfer, or a Book-Entry Confirmation, as the case may be, and all other
documents required by this Letter are received by the Exchange Agent within
three New York Stock Exchange trading days after the Expiration Date.

    The method of delivery of this Letter, the Old Notes and all other required
documents is at the election and risk of the tendering holders. Instead of
delivery by mail, it is recommended that holders use an overnight or hand
delivery service. In all cases, sufficient time should be allowed to assure
delivery to the Exchange Agent before the Expiration Date. No Letter of
Transmittal or Old Notes should be sent to the Company. Holders may request
their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the tenders for such holders.

    See "The Exchange Offer" section of the Prospectus.

2. Partial Tenders; Withdrawals.

    If less than all of the Old Notes evidenced by a submitted certificate are
to be tendered, the tendering holder(s) should fill in the aggregate principal
amount at maturity of Old Notes tendered in the box entitled "Description of
Old Notes--Principal Amount at Maturity Tendered." A newly issued

                                       7


certificate for the Old Notes submitted but not tendered will be sent to such
holder as soon as practicable after the Expiration Date. All Old Notes
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise clearly indicated.

    If not yet accepted, a tender pursuant to the Exchange Offer may be
withdrawn prior to the Expiration Date. To be effective with respect to the
tender of Old Notes, a notice of withdrawal must: (i) be received by the
Exchange Agent before the Company notifies the Exchange Agent that it has
accepted the tender of Old Notes pursuant to the Exchange Offer; (ii) specify
the name of the Old Notes; (iii) contain a description of the Old Notes to be
withdrawn, the certificate numbers shown on the particular certificates
evidencing such Old Notes and the principal amount at maturity of Old Notes
represented by such certificates; and (iv) be signed by the holder in the same
manner as the original signature on this Letter (including any required
signature guarantee). The Exchange Agent will return the properly withdrawn Old
Notes promptly following receipt of notice of withdrawal. If Old Notes have
been tendered pursuant to the procedure for book-entry transfer, any notice of
withdrawal must specify the name and number of the account at the book-entry
transfer facility to be credited with the withdrawn Old Notes or otherwise
comply with the book-entry transfer facility's procedures. All questions as to
the validity of notices of withdrawals, including time of receipt, will be
determined by the Company, and such determination will be final and binding on
all parties.

3. Signatures on this Letter, Bond Powers and Endorsements; Guarantee of
Signatures.

    If this Letter is signed by the registered holder of the Old Notes tendered
hereby, the signature must correspond exactly with the name as written on the
face of the certificates without alteration, enlargement or any change
whatsoever.

    If any tendered Old Notes are owned of record by two or more joint owners,
all such owners must sign this Letter.

    If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate copies of this Letter as there are different registrations of
certificates.

    When this Letter is signed by the registered holder (which term, for the
purposes described herein, shall include the book-entry transfer facility whose
name appears on a security listing as the owner of the Old Notes) of the Old
Notes specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If, however, the New Notes are to be issued
to a person other than the registered holder, then endorsements of any
certificates transmitted hereby or separate bond powers are required.
Signatures on such certificate(s) must be guaranteed by an Eligible Institution
(as defined below).

    If this Letter is signed by a person other than the registered holder or
holders of any Old Notes specified therein, such certificate(s) must be
endorsed by such registered holder(s) or accompanied by separate written
instruments of transfer or endorsed in blank by such registered holder(s)
exchange in form satisfactory to the Company and duly executed by the
registered holder, in either case signed exactly as such registered holder(s)
name or names appear(s) on the Old Notes.

    If the Letter or any certificates of Old Notes or separate written
instruments of transfer or exchange are signed or endorsed by trustees,
executors, administrators, guardians, attorney-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter.

    Signature on a Letter or a notice of withdrawal, as the case may be, must
be guaranteed by an Eligible Institution unless the Old Notes tendered pursuant
thereto are tendered (i) by a registered

                                       8


holder who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on the Letter or (ii) for the account of an
Eligible Institution. In the event that signatures on a Letter or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantee
must be by a member firm of a registered national securities exchange or of the
National Association of Securities Dealers, Inc., a commercial bank or trust
company having an office or correspondent in the United States or an "eligible
guarantor institution" within the meaning of Rule 17Ad-15 under the Securities
Exchange Act of 1934, as amended (an "Eligible Institution").

4. Special Issuance and Delivery Instructions.

    Tendering holders of Old Notes should indicate in the applicable box the
name and address to which New Notes issued pursuant to the Exchange Offer are
to be issued or sent, if different from the name or address of the person
signing this Letter. In the case of issuance in a different name, the employer
identification or social security number of the person named must also be
indicated. Holders tendering Old Notes by book-entry transfer may request that
Old Notes not exchanged be credited to such account maintained at the Book-
Entry Transfer Facility as such noteholder may designate hereon. If no such
instructions are given, such Old Notes not exchanged will be returned to the
name or address of the person signing this Letter.

5. Tax Identification Number.

    Federal income tax law generally requires that a tendering holder whose Old
Notes are accepted for exchange must provide the Company (as payor) with such
holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9
below or otherwise establish a basis for exemption from backup withholding. If
such holder is an individual, the TIN is his or her social security number. If
the Company is not provided with the current TIN or an adequate basis for an
exemption, such tendering holder may be subject to a $50 penalty imposed by the
Internal Revenue Service. In addition, delivery to such tendering holder of New
Notes may be subject to backup withholding in an amount up to 31% of all
reportable payments made after the exchange.

    Certain holders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. See the enclosed Guidelines of Certification of Taxpayer
Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for
additional instructions.

    To prevent backup withholding, each tendering holder of Old Notes must
provide its correct TIN by completing the "Substitute Form W-9" set forth
below, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN) and that (i) the holder is exempt from backup withholding,
(ii) the holder has not been notified by the Internal Revenue Service that such
holder is subject to a backup withholding as a result of a failure to report
all interest or dividends or (iii) the Internal Revenue Service has notified
the holder that such holder is no longer subject to backup withholding. If the
tendering holder of Old Notes is a nonresident alien or foreign entity not
subject to backup withholding, such holder must give the Company a completed
Form W-8, Certificate of Foreign Status. These forms may be obtained from the
Exchange Agent. If the Old Notes are in more than one name or are not in the
name of the actual owner, such holder should consult the W-9 Guidelines for
information on which TIN to report. If such holder does not have a TIN, such
holder should consult the W-9 Guidelines for instructions on applying for a
TIN, check the box in Part 2 of the Substitute Form W-9, write "applied for" in
lieu of its TIN and complete the Certificate of Awaiting Taxpayer
Identification Number. Note: checking this box and writing "applied for" on the
form means that such holder has already applied for a TIN or that such holder
intends to apply for one in the near future. If a holder checks the box in Part
2 of the Substitute Form W-9 and writes "applied for" on that form, backup
withholding at a rate of up to 31% will nevertheless apply to all reportable

                                       9


payments made to such holder. If such a holder furnishes its TIN to the Company
within 60 days, however, any amounts so withheld shall be refunded to such
holder.

    Backup withholding is not an additional Federal income tax. Rather, the
Federal income tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in overpayment of
taxes, a refund may be obtained from the Internal Revenue Service.

6. Transfer Taxes.

    Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith. If, however, New Notes are to
be delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered hereby, or if tendered Old Notes
are registered in the name of any person other than the person signing this
Letter, or if a transfer tax is imposed for any reason other than the exchange
of Old Notes in connection with the Exchange Offer, the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted herewith, the amount of such
transfer taxes will be billed directly to such tendering holder.

    Except as provided In this Instruction 5, It will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter.

7. Waiver of Conditions.

    The Company reserves the right to waive satisfaction of any or all
conditions enumerated in the Prospectus.

8. No Conditional Tenders.

    No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Notes by execution of this Letter, shall
waive any right to receive notice of the acceptance of their Old Notes for
exchange.

    Neither the Company, the Exchange Agent nor any other person is obligated
to give notice of any defect or irregularity with respect to any tender of Old
Notes nor shall any of them incur any liability for failure to give any such
notice.

9. Mutilated, Lost, Stolen or Destroyed Old Notes.

    Any holder whose Old Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above for further
instructions.

10.  Requests for Assistance or Additional Copies.

    Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter, may be directed to the
Exchange Agent, at the address and telephone number indicated above.
