EXHIBIT 10.15



                           CHANGE OF CONTROL AGREEMENT


                  This is a CHANGE OF CONTROL AGREEMENT ("Agreement") dated
October 10, 2000, between Airgas, Inc., a Delaware corporation (the "Company"),
and Glenn Fischer (the "Executive").


                                   BACKGROUND

                  Executive is the current President and Chief Operating Officer
of the Company. The Board of Directors of the Company (the "Board") has
determined it is in the Company's best interest to assure that the Company will
have the continued dedication of Executive, notwithstanding the possibility,
threat or occurrence of a Change of Control of the Company, as will be defined
below. To diminish the inevitable distraction to Executive by virtue of the
personal uncertainties and risks created by a pending or threatened Change of
Control, to encourage Executive's full attention and dedication to the Company
currently and in the event of any Change of Control, and to provide Executive
with compensation arrangements upon a Change of Control that provide Executive
financial security and that are competitive with peer corporations of the
Company, the Company and Executive desire to enter into this Agreement that is
in the best interests of the Company and Executive.

                  NOW, THEREFORE, intending to be legally bound, and in
consideration of the mutual promises and representations set forth in this
Agreement, the Company and Executive agree as follows:

                          ARTICLE I - TERM OF AGREEMENT

         1.1 TERM. The term of this Agreement shall commence as of the date
hereof, and shall terminate upon the earlier of (i) Executive's termination of
employment with the Company for any reason, or (ii) the later of (A) date which
is three years following the date on which a Change of Control, as defined in
Section 2.2, occurred; or (B) the date as of which funding is required under
3.5.2 following a Standstill Agreement provided, however, that the Agreement
shall remain in effect until Executive (or Executive's beneficiary if Executive
is not alive) has received any and all amounts to which Executive is entitled
under Article III, if any.

               ARTICLE II - TERMINATION OF EXECUTIVE'S EMPLOYMENT

         2.1 CHANGE OF CONTROL REQUIRED. No amounts or benefits shall be paid or
become payable to Executive under this Agreement unless a Change of Control, as
defined in Section 2.2, occurs.

         2.2 CERTAIN DEFINITIONS. For purposes of this Agreement:

                  2.2.1 A "Change of Control" shall mean any one or more of the
         following:

                           2.2.1.1 As a result of a tender offer, stock
                  purchase, other stock acquisition, merger, consolidation,
                  recapitalization, reverse split, sale or transfer of any asset
                  or other transaction any person or group (as such terms are
                  used in and under Section 13(d) of the Securities Exchange Act
                  of 1934 (the "Exchange Act")) other than the Company, any
                  affiliate, or any employee benefit plan of the Company or an
                  affiliate, shall become the beneficial owner (as defined in
                  Rule 13-d under the Exchange Act) directly or indirectly of
                  securities of the Company representing 20% or more of the
                  combined voting power of the Company's then outstanding
                  securities; providing, however, that this provision shall not
                  apply to Peter McCausland ("McCausland"), unless and until
                  McCausland, together with all affiliates and associates,
                  becomes the beneficial owner of 30% or more of the combined
                  voting power of the Company's then outstanding securities;

                           2.2.1.2 Stockholders approve the consummation of any
                  merger of the Company or any sale or other disposition of all
                  or substantially all of its assets, if the Company's
                  stockholders immediately before such transaction own,
                  immediately after consummation of such transaction, equity
                  securities (other than options and other rights to acquire
                  equity securities) possessing less than 50% of the voting
                  power of the surviving or acquiring corporation; or

                           2.2.1.3 A change in the majority of the individuals
                  who constitute the Board occurs during any period of two years
                  for any reason without the approval of at least a majority of
                  directors in office at the beginning of such period.

                  2.2.2 A "Potential Change of Control" shall be deemed to have
         occurred if:


                                     - 2 -
<Page>

                           2.2.2.1 The Company enters into an agreement, the
                  consummation of which would result in the occurrence of a
                  Change of Control of the Company;

                           2.2.2.2 Any person (including the Company) publicly
                  announces an intention to take or to consider taking actions
                  which if consummated would constitute a Change of Control of
                  the Company;

                           2.2.2.3 Any person, other than a trustee or other
                  fiduciary holding securities under an employee benefit plan of
                  the Company or a corporation owned, directly or indirectly, by
                  the stockholders of the Company in substantially the same
                  proportions as their ownership of stock of the Company, who is
                  or becomes the beneficial owner, directly or indirectly, of
                  securities of the Company representing 10% or more of the
                  combined voting power of the Company's then outstanding
                  securities, increases his beneficial ownership of such
                  securities by 5% or more of the combined voting power of the
                  Company's then outstanding securities on the effective date of
                  this Agreement; provided, that this Section 2.2.2.3 shall not
                  apply to an increase in ownership by McCausland; or

                           2.2.2.4 The Board adopts a resolution to the effect
                  that, for purposes of this Agreement, a "Potential Change of
                  Control" has occurred.

                  2.2.3 A "Triggering Event" means a Potential Change of Control
or a Change of Control.

         2.3 TERMINATION OF EXECUTIVE'S EMPLOYMENT ENTITLING EXECUTIVE TO
BENEFITS. A termination of Executive's employment In Connection With a Change of
Control (as hereinafter defined), for any reason set forth in this Section 2.3
shall entitle Executive to the amounts and benefits set forth in Section 3.1.
Such termination shall be considered "In Connection With a Change of Control" if
such termination occurs (i) within three years following a Change of Control or
(ii) following a Potential Change of Control but before an actual Change of
Control, provided the Potential Change of Control results in a Change of Control
within one year following the Potential Change of Control.

                  2.3.1 VOLUNTARY TERMINATION FOR GOOD REASON. Executive may
notify the Company of Executive's intention to terminate employment with the
Company for Good Reason, as hereinafter defined, In Connection With a Change of
Control. The Company shall have 30 days to cure the defects stated in such
notice


                                     - 3 -
<Page>

that would give rise to a termination for Good Reason. If the Company has not
cured all such defects at the end of that 30-day period, Executive may terminate
employment with the Company effective, for purposes of this Agreement, as of the
date that Executive provided notice to the Company pursuant to the first
sentence of this Section 2.3.1, and Executive shall be entitled to the amounts
and benefits set forth in Section 3.1. For purposes of this Agreement, "Good
Reason" shall mean any of the following:


                           2.3.1.1 Any change in Executive's total compensation
                  and benefits package from the Company that, in the aggregate,
                  materially decreases Executive's total compensation. Such
                  changes include, but are not limited to, a decrease in
                  Executive's annual base salary, a decrease in any incentive
                  compensation opportunity, a decrease in any material benefit
                  plan, program or policy in which Executive is participating at
                  the time of a Triggering Event, or the taking of any action by
                  the Company that would adversely affect Executive's
                  participation in or materially reduce Executive's opportunity
                  to receive benefits under any such benefit plan, program or
                  policy or that would deprive Executive of any material fringe
                  benefit enjoyed by Executive at the time of a Triggering
                  Event; provided, however, that no single decrease shall be
                  determinative, but rather the aggregate of all such decreases
                  and any increases in compensation or benefits shall determine
                  whether there has been a material decrease in Executive's
                  total compensation and benefits package; or

                           2.3.1.2 Executive's relocation to any location more
                  than 35 miles from the location at which Executive performed
                  his duties prior to a Triggering Event, except for required
                  travel by Executive on the Company's business to an extent
                  substantially consistent with Executive's business travel
                  obligations prior to a Triggering Event.

                  2.3.2 INVOLUNTARY TERMINATION OTHER THAN FOR CAUSE. If the
Company terminates Executive's employment other than for Cause, as defined in
Section 2.4, In Connection With a Change of Control, Executive shall be entitled
to the amounts and benefits set forth in Section 3.1.

         2.4 CAUSE DEFINED. Executive's termination of employment with the
Company shall be for "Cause" if one or more of the following events occur:

                  2.4.1 Executive's willful misconduct or gross negligence in
the performance of Executive's duties;


                                     - 4 -
<Page>

                  2.4.2 Executive's commission of any act of fraud or
embezzlement against the Company or Executive's commission of a felony or any
other offense involving moral turpitude; or

                  2.4.3 Executive's unauthorized dissemination of confidential
information, observations, and data concerning the business plans, financial
data, customer lists, trade secrets and acquisitions strategies of the Company
and its subsidiaries which has a material adverse effect on the Company or its
subsidiaries.

         2.5 NO OTHER AMOUNTS PAYABLE. Except as provided in Section 2.3, no
amounts or benefits shall be paid or become payable to Executive under this
Agreement.


                             ARTICLE III - BENEFITS

         3.1 BENEFITS. If Executive's employment with the Company terminates in
a manner described in Section 2.3, the Company shall pay Executive the following
amounts and provide to Executive the following benefits, subject to Sections
3.3:

                  3.1.1 CASH PAYMENT. As soon as practicable, but not later than
60 days following the later of (i) Executive's termination of employment, or
(ii) the Change of Control, the Company shall make a lump sum payment to
Executive equal to three times the sum of (x) and (y), as described immediately
hereafter. For this purpose, (x) equals the greater of Executive's annual base
salary as in effect (a) immediately prior to Executive's termination, or (b) at
the time a Triggering Event occurred, and (y) equals the potential bonus amount
determined for Executive under the Company's bonus plan for the fiscal year of
the Company in which a Triggering Event occurred (or, if no such bonus amount
has been determined for any such fiscal year, the immediately preceding fiscal
year of the Company) as if 100% of plan established pursuant to such bonus plan
were achieved and the maximum level of the discretionary portion were achieved.

                  3.1.2 HEALTH AND WELFARE BENEFITS. For a period of three years
following Executive's termination of employment, the Company shall continue to
provide Executive with medical, dental, prescription drug, life, accidental
death, and disability (short-term and long-term) insurance benefits at the same
level and cost to Executive as were in effect immediately prior to Executive's
termination. If the Executive's employment terminates after a Potential Change
of Control and no Change of Control occurs within one year of the Potential
Change of Control, such benefits shall continue only until the expiration of
such one-year period. However,


                                     - 5 -
<Page>

the above benefits shall terminate if Executive is entitled to comparable
coverage from a subsequent employer, to the extent permitted under Code section
4980B. The Executive and his dependents shall continue to receive or be eligible
for benefits under the Company's Scholarship and Tuition Reimbursement Programs
as if the Executive remained employed by the Company for the remainder of the
relevant academic year(s) in which the Executive's employment terminates.

                  3.1.3 STOCK OPTIONS AND RESTRICTED STOCK. All stock options
and restricted stock grants awarded to Executive under any stock option or stock
grant plans of the Company shall become fully vested upon a Change of Control
and, notwithstanding any provision of any such option plan to the contrary, any
stock option shall remain exercisable until that option's expiration date,
determined without regard to Executive's termination of employment.

         3.2 REDUCTION OF BENEFITS.

                  3.2.1 REDUCED PAYMENT. If any payment or benefit provided to
Executive by the Company pursuant to this Agreement or otherwise (the "Payment")
shall be determined to be an "Excess Parachute Payment," (as defined in Code
section 280G(b)(1)), that would be subject to the excise tax imposed by Code
Section 4999, then the aggregate present value of amounts or benefits payable to
Executive pursuant to this Agreement (the "Agreement Payments") shall be reduced
(but not below zero) to the Reduced Amount. The "Reduced Amount" shall be an
amount expressed in present value that maximizes the aggregate present value of
Agreement Payments without causing any payments or benefits hereunder to be an
Excess Parachute Payment. Anything to the contrary notwithstanding, if the
Reduced Amount is zero and it is determined further that any payment from the
Company to Executive that is not an Agreement Payment would nevertheless be an
Excess Parachute Payment, then the aggregate present value of Payments that are
not Agreement Payments shall also be reduced (but not below zero) to an amount,
if any, if the present value of such lesser amount maximizes the aggregate
present value of Payments to Executive on an after-tax basis, taking into
account income and excise taxes under section 1 and section 4999 of the Code.
For purposes of this Section 3.2 present value shall be determined in accordance
with section 280G(d)(4) of the Code.

                  3.2.2 DETERMINATION OF AGREEMENT PAYMENTS. All determinations
required under this Section 3.2 shall be made by a national accounting firm
retained by the Company at its own expense. The accounting firm shall provide
the Company and the Executive with a report and supporting calculations within
15 business days of the date Executive's employment with the Company terminates
or such earlier time as is requested by the Company. In addition, the accounting
firm


                                     - 6 -
<Page>

shall provide an opinion to Executive that the Executive has substantial
authority not to report any excise tax on Executive's federal income tax return
with respect to the Agreement Payments. Any such determination by the accounting
firm shall be binding upon the Company and Executive. Executive shall determine
which and how much of the Agreement Payments or Payments, as the case may be,
shall be eliminated or reduced consistent with the requirements of this Section
3.2, provided that, if Executive does not make such determination within 10
business days of the receipt of the calculations from the accounting firm, the
Company shall elect which and how much of the Agreement Payments or Payments, as
the case may be, shall be eliminated or reduced consistent with the requirements
of this Section 3.2 and shall notify Executive promptly of such election. Within
10 business days thereafter, the Company shall pay to or distribute to or for
the benefit of Executive such amounts are then due to Executive under this
Agreement.

         3.3 DEFERRAL OF BENEFITS. If the Company, based on written advice of
reputable counsel, a copy of which shall be provided to Executive, determines
that in the aggregate any benefit or payment under this Agreement and under any
other arrangement or agreement between the Company and Executive would not be
deductible for federal income taxes by the Company solely as a result of the
application of section 162(m) of the Code, the payment of any amounts otherwise
payable under this Agreement in the then current year shall be reduced, but not
below zero, by the amount of any such non-deductible amounts. The Company shall
pay the entire non-deductible amount to Executive at the earliest possible time
or times that such amounts (or portions thereof) may be paid to Executive
without such amounts being non-deductible under Code section 162(m), along with
interest accrued on such amounts since the date they would have been payable but
for this Section 3.3 calculated at the applicable federal short-term rate. If
any other agreement between the Company and Executive provides for the deferral
of payments from the Company to Executive solely as a result of the application
of Code section 162(m), the deferral provisions in this Agreement shall prevail
and all deferrals shall be made from amounts payable under Section 3.1 of this
Agreement before any amounts may be deferred under any other arrangements solely
as a result of the application of Code section 162(m).

         3.4 WITHHOLDING TAXES. The Company shall withhold from any payments or
benefits made under this Agreement all applicable federal, state and local
income and employment taxes, as well as any other amounts required to be
withheld under any law.

         3.5 FUNDING.

                  3.5.1 REQUIRED FUNDING. The Company shall not be required to


                                     - 7 -
<Page>

fund in advance the amounts and benefits payable under this Agreement until a
Triggering Event occurs. Upon the occurrence of a Triggering Event, the Company
shall immediately contribute an amount to an irrevocable grantor trust, of which
Executive is the beneficiary and a third-party is the trustee (a "Trust"), equal
to 120% of the amounts that could become payable to Executive under this
Agreement.

                  3.5.2 STANDSTILL AGREEMENTS. Notwithstanding Section 3.5.1, if
a transaction is approved by the Board, including one that would constitute a
Change of Control, and the transaction is accompanied by a Board approved
standstill agreement that provides for (i) no further acquisition of Company
securities by the shareholder(s) entering into the agreement and (ii) management
autonomy for the Company's management at the time the agreement is executed (a
"Standstill Agreement"), the Board shall determine whether to contribute amounts
to a Trust to fund benefits payable under this Agreement at the time the
Standstill Agreement is executed. The Company shall fund such a Trust, however,
if after such a transaction and the execution of a Standstill Agreement (i) the
terms of the Standstill Agreement, including the management autonomy provision,
are violated or (ii) the Company terminates any of its executive officers
without Cause, as defined in Section 2.4. If a Trust is to be funded under this
Section 3.5.2, the Company shall immediately contribute an amount to the Trust
equal to 120% of the amounts that could become payable to Executive under this
Agreement.

                  3.5.3 PAYMENTS FROM TRUST AND REVERSIONS. To the extent any
provision of this Agreement provides for a payment from the Company to
Executive, the Company may direct the trustee of a Trust created pursuant to
this Section 3.5 to make such payment to the extent that any remaining assets in
the Trust are reasonably expected to be sufficient for any additional amounts or
benefits that may be due Executive from the Company under this Agreement. No
amount in a Trust may revert to the Company until 90 days after the expiration
of the Term of this Agreement. Notwithstanding the above, (i) if the Triggering
Event causing a Trust to be funded under Section 3.5.1 is a Potential Change of
Control and no Change of Control occurs within one year of the Potential Change
of Control, amounts in the Trust may revert to the Company at the expiration of
such one-year period, and (ii) if Executive has brought a lawsuit against the
Company claiming amounts or benefits under this Agreement, no amounts from the
Trust shall revert to the Company while such claim is pending.

         3.6 LEGAL EXPENSES. If Executive determines in good faith to retain
legal counsel and/or to incur other reasonable costs or expenses in order to
enforce any or all of Executive's rights under this Agreement, the Company shall
pay all such attorneys' fees, costs and expenses incurred in connection with
non-frivolous applications to interpret or enforce Executive's rights. In
addition, during the


                                     - 8 -
<Page>

pendency of any such controversy or claim, the Company will continue to pay
Executive, with the customary frequency, the greater of Executive's base pay as
in effect immediately prior to the Triggering Event or immediately prior to
Executive's termination of employment, and, to the extent permitted under law,
to provide the Executive with the same benefits Executive was receiving
immediately prior to the Triggering Event until the controversy or claim finally
is resolved. These payments and the provision of benefits hereunder shall be in
addition to, and not in derogation or mitigation of any other payment or benefit
due Executive under this Agreement.

         3.7 NO DUTY OF MITIGATION. The Executive shall have no duty to seek new
employment after his employment with the Company terminates or to take any other
actions which could reduce the amounts the Company is obligated to pay or reduce
the benefits the Company is required to provide under this Agreement.

                           ARTICLE IV - MISCELLANEOUS

         4.1 MODIFICATION OF THIS AGREEMENT. Executive acknowledges and agrees
that no one employed by or representing the Company has any authority to make
oral statements which modify, waive or discharge, in any manner, any provision
of this Agreement. Executive further acknowledges and agrees that no provision
of this Agreement may be modified, waived or discharged unless agreed to in
writing, and signed and executed by Executive and the Board, or its delegate.

not relied upon any representation or statement made by the Company or its

Executive provides otherwise, the Company and Executive acknowledge that,
notwithstanding this Agreement, the employment of Executive by the Company is
"at will," and the Company may terminate Executive's employment with the Company
at any time, although certain terminations as specified in Article II will
