          This EMPLOYMENT AGREEMENT (this "Agreement") is entered into by and
between Fisher Scientific International, Inc., a Delaware corporation (the
"Company") and Paul M. Montrone (the "Executive"), dated as of the 31st day of
December, 2001.

          1.   TERM OF THE AGREEMENT. This Agreement shall commence as of
December 31, 2001 (the "Effective Date") and end on December 31, 2006 (the
"Initial Employment Period" and, together with any extensions thereof pursuant
to the next sentence, the "Employment Period"). As of the last day of the
Initial Employment Period and each anniversary thereof, unless either party
hereto shall have given the other party 60 days' advance notice that there shall
be no further extensions pursuant to this sentence (such notices, a "Notice of
Non-Extension"), the Employment Period shall be extended by an additional year.

          2.   POSITION AND DUTIES. During the Employment Period, the
Executive's position (including status, offices, titles and reporting
requirements), authority, duties and responsibilities shall be at least
commensurate in all material respects with those held, exercised and assigned to
the Executive on the day immediately preceding the Effective Date. The
Executive's services shall be performed at the location where the Executive was
employed immediately preceding the Effective Date or any office or location less
than 25 miles from such location. During the Employment Period, and excluding
any periods of vacation and sick leave to which the Executive is entitled, the
Executive agrees to devote reasonable attention and time during normal business
hours to the business and affairs of the Company and, to the extent necessary to
discharge the responsibilities assigned to the Executive hereunder, to use the
Executive's reasonable best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic, charitable,
governmental or religious boards or committees, (B) to manage or participate in
activities of General Chemical Group, GenTek Inc.and Latona Associates, Inc., in
a manner consistent with his current practice, (C) deliver lectures, fulfill
speaking engagements or teach at educational institutions, (D) participate in
political activities and fundraising and (E) manage personal investments, so
long as such activities do not significantly interfere with the performance of
the Executive's responsibilities as an employee of the Company in accordance
with this Agreement. It is expressly understood and agreed that to the extent
that any such activities have been conducted by the Executive prior to the
Effective Date, the continued conduct of such activities (or the conduct of
activities similar in nature and scope thereto) subsequent to the Effective Date
shall not thereafter be deemed to interfere with the performance of the
Executive's responsibilities to the Company.

          3.   COMPENSATION.

          (a)  BASE SALARY. During the Employment Period, the Executive shall
receive an annual base salary of at least $815,000 ("Annual Base Salary"),
which shall be paid in accordance with the Company's generally applicable
payroll practices and policies. During the Employment Period, the Annual Base
Salary shall be reviewed at least annually. Any increase in Annual Base Salary
shall not serve to limit or reduce any other obligation to the Executive under
this Agreement. Annual Base Salary shall not be reduced after any such increase
and the term Annual Base Salary as utilized in this Agreement shall refer to
Annual Base Salary as so increased.

          (b)  ANNUAL BONUS. In addition to Annual Base Salary, the Executive
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to $475,000 (the
"Minimum Bonus Amount"). Each such Annual Bonus shall be paid no later than the
end of the third month of the fiscal year next following the fiscal year for
which the Annual Bonus is awarded, unless the Executive shall elect to defer the
receipt of such Annual Bonus.

          (c)  INCENTIVE, SAVINGS AND RETIREMENT PLANS. During the Employment
Period, the Executive shall be entitled to participate in all incentive, savings
and retirement plans, practices, policies and programs applicable generally to
other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with incentive opportunities (measured with respect to both regular and special
incentive opportunities, to the extent, if any, that such distinction is
applicable), savings opportunities and retirement benefit opportunities, in each
case, less favorable, in the aggregate, than the most favorable of those
provided by the Company and its affiliated companies for the Executive under
such plans, practices, policies and programs as in effect immediately preceding
the Effective Date or if more favorable to the Executive, those provided
generally at any time after the Effective Date to other peer executives of the
Company and its affiliated companies.

          (d)  WELFARE BENEFIT PLANS. During the Employment Period, the
Executive and/or the Executive's family, as the case may be, shall be eligible
for participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable generally
to other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with benefits which are less favorable, in the aggregate, than the most
favorable of such plans, practices, policies and programs in effect for the
Executive


                                       2


<PAGE>


immediately preceding the Effective Date or, if more favorable to the Executive,
those provided generally at any time after the Effective Date to other peer
executives of the Company and its affiliated companies. Without limiting the
generality of the foregoing, the Company shall continue to make all required
premium payments and fulfill its other obligations under the split-dollar
insurance agreement (the "Split-Dollar Agreement") entered into by the Company
and the Executive and effective as of November 8, 1994.

          (e)  EXPENSES. During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the most favorable policies, practices and
procedures of the Company and its affiliated companies in effect for the
Executive immediately preceding the Effective Date or, if more favorable to the
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

          (f)  FRINGE AND OTHER BENEFITS. During the Employment Period, the
Executive shall be entitled to fringe benefits, personal perquisites, and any
other benefits in accordance with the most favorable plans, practices, programs
and policies of the Company in all respects and its affiliated companies in
effect for the Executive immediately preceding the Effective Date or, if more
favorable to the Executive, as in effect generally at any time thereafter with
affiliated companies, including, without limitation, benefits payable under the
Executive's Split-Dollar Agreement.

          (g)  OFFICE AND SUPPORT STAFF. During the Employment Period, the
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to secretarial and other assistance, in
all respects equal to that provided to the Executive by the Company immediately
preceding the Effective Date or, if more favorable to the Executive, as provided
generally at any time thereafter with respect to other peer executives of the
Company and its affiliated companies.

          (h)  VACATION. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the plans, policies, programs and
practices of the Company in all respects and its affiliated companies as in
effect for the Executive immediately preceding the Effective Date or, if more
favorable to the Executive, as in effect generally at any time thereafter with
respect to other peer executives of the Company and its affiliated companies.

          4.   TERMINATION OF EMPLOYMENT.

          (a)  DEATH OR DISABILITY. The Executive's employment shall terminate
automatically upon the Executive's death during the Employment Period. If the
Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below), it


                                       3

<PAGE>


may give to the Executive written notice in accordance with Section 10(b) of
this Agreement of its intention to terminate the Executive's employment. In such
event, the Executive's employment with the Company shall terminate effective on
the 30th day after receipt of such notice by the Executive (the "Disability
Effective Date"), provided that, within the 30 days after such receipt, the
Executive shall not have returned to full-time performance of the Executive's
duties. For purposes of this Agreement, "Disability" shall mean the absence of
the Executive from the Executive's duties with the Company on a full-time basis
for 180 consecutive business days as a result of incapacity due to mental or
physical illness which is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Executive or the
Executive's legal representative.

          (b)  CAUSE. The Company may terminate the Executive's employment
during the Employment Period for Cause. For purposes of this Agreement, "Cause"
shall mean:

               (i) the willful and continued failure of the Executive to perform
          substantially the Executive's duties with the Company or one of its
          affiliates (other than any such failure resulting from incapacity due
          to physical or mental illness), after a written demand for substantial
          performance is delivered to the Executive by the Board or the Chief
          Executive Officer of the Company which specifically identifies the
          manner in which the Board or Chief Executive Officer believes that the
          Executive has not substantially performed the Executive's duties, or

               (ii) the willful engaging by the Executive in illegal conduct or
          gross misconduct that is materially and demonstrably injurious to the
          Company.

          For purposes of this provision, no act or failure to act, on the part
          of the Executive, shall be considered "willful" unless it is done, or
          omitted to be done, by the Executive in bad faith or without
          reasonable belief that the Executive's action or omission was in the
          best interests of the Company. Any act, or failure to act, based upon
          authority given pursuant to a resolution duly adopted by the Board or
          upon the instructions of the Chief Executive Officer or a senior
          officer of the Company or based upon the advice of counsel for the
          Company shall be conclusive presumed to be done, or omitted to be
          done, by the Executive in good faith and in the best interests of the
          Company. The cessation of employment of the Executive shall not be
          deemed to be for Cause unless and until there shall have been
          delivered to the Executive a copy of a resolution duly adopted by the
          affirmative vote of not less than three-quarters of the entire
          membership of the Board at a meeting of the Board called and held for
          such purpose (after reasonable notice is provided to the Executive and
          the Executive is given an opportunity, together with counsel, to be
          heard before the Board), finding that, in the good

                                       4

<PAGE>

          faith opinion of the Board, the Executive is guilty of the conduct
          described in subparagraph (i) or (ii) above, and specifying the
          particulars thereof in detail.

          (c)  GOOD REASON. The Executive's employment may be terminated by the
Executive other than for Good Reason, or by the Executive for Good Reason at any
time within 90 days after the Executive first has actual knowledge of the
occurrence of such Good Reason. For purposes of this Agreement, "Good Reason"
shall mean:

               (i) the assignment to the Executive of any duties inconsistent in
          any respect with the Executive's position (including status, offices,
          titles and reporting requirements), authority, duties or
          responsibilities as contemplated by Section 2 of this Agreement, or
          any other action by the Company which results in a diminution in such
          position, authority, duties or responsibilities, excluding, for this
          purpose an isolated, insubstantial and inadvertent action not taken in
          bad faith and which is remedied by the Company promptly after receipt
          of notice thereof given by the Executive;

               (ii) any failure by the Company to comply with any of the
          provisions of Section 3 of this Agreement, other than an isolated,
          insubstantial and inadvertent failure not occurring in bad faith and
          which is remedied by the Company promptly after receipt of notice
          thereof given by the Executive;

               (iii) the Company's requiring the Executive to be based at any
          office or location other than as provided in Section 2 hereof or the
          Company's requiring the Executive to travel on Company business to a
          substantially greater extent than required immediately prior to the
          Effective Date;

               (iv) any purported termination by the Company of the Executive's
          employment otherwise than as expressly permitted by this Agreement;

               (v) any delivery by the Company of a Notice of Non-Extension; or

               (vi) any failure by the Company to comply with and satisfy
          Section 9 of this Agreement.

For purposes of this Section 4(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive.

          (d)  NOTICE OF TERMINATION. Any termination by the Company for Cause,
or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 10(b) of
this Agreement. For purposes of this Agreement, a "Notice of Termination" means
a written notice which (I) indicates the specific termination provision in this
Agreement relied upon, (II) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to


                                       5

<PAGE>


provide a basis for termination of the Executive's employment under the
provision so indicated and (III) if the Date of Termination (as defined below)
is other than the date of receipt of such notice, specifies the termination date
(which date shall be not more than thirty days after the giving of such notice).
The failure by the Executive or the Company to set forth in the Notice of
Termination any fact or circumstance which contributes to a showing of Good
Reason or Cause shall not waive any right of the Executive or the Company,
respectively, hereunder or preclude the Executive or the Company, respectively,
from asserting such fact or circumstance in enforcing the Executive's or the
Company's rights hereunder.

          (e)  DATE OF TERMINATION. "Date of Termination" means (I) if the
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (II) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
date on which the Company notifies the Executive of such termination, (III) if
the Executive's employment is terminated by the Executive other than for Good
Reason, the date on which the Executive notifies the Company of such termination
and (IV) if the Executive's employment is terminated by reason of death or
Disability, the date of death of the Executive or the Disability Effective Date,
as the case may be.

          5.   OBLIGATIONS OF THE COMPANY UPON TERMINATION.

          (a)  BY EXECUTIVE; OTHER THAN FOR CAUSE, DEATH OR DISABILITY. In
partial consideration for the confidential information and noncompetition
covenants of the Executive pursuant to Section 8 and in part as liquidated
damages in lieu of the payments and benefits to which the Executive would have
been entitled through the remainder of the Employment Period, if, during the
Employment Period, the Company shall terminate the Executive's employment other
than for Cause or Disability or the Executive shall terminate employment for
Good Reason or without Good Reason:

               (i) the Company shall pay to the Executive in a lump sum in cash
          within 30 days after the Date of Termination the aggregate of the
          following amounts:

                    A.   the sum of

                         (1) the Executive's Annual Base Salary through the Date
                         of Termination to the extent not theretofore paid,

                         (2) the product of

                                       6

<PAGE>


                    (a) The Executive's target bonus as determined under the
                    applicable Fisher compensation plan(s), and

                    (b) a fraction, the numerator of which is the number of days
                    in the current fiscal year through the Date of Termination,
                    and the denominator of which is 365 and

               (3) any compensation previously deferred by the Executive
               (together with any accrued interest or earnings thereon) and any
               accrued vacation pay, in each case to the extent not theretofore
               paid (the sum of the amounts described in clauses (1), (2), and
               (3) shall be hereinafter referred to as the "Accrued
               Obligations"); and

          B.   the amount equal to the product of

               (1) five (three in the case of termination by the Executive
               without Good Reason) and

               (2) the sum of

                    (a) the Executive's Annual Base Salary and

                    (b) The Executive's target bonus as determined under the
                    applicable Fisher compensation plan(s) and

          C.   an amount equal to the difference between (A) the aggregate
     benefit under the Company's qualified - defined benefit retirement plans
     (collectively, the "Retirement Plan") and any excess or supplemental
     defined benefit retirement plans in which the Executive participates,
     including without limitation the Company's Executive Retirement and Savings
     Plan, (collectively, the "SERP") which the Executive would have accrued
     (whether or not vested) if the Executive's employment had continued for
     five years (three years in the case of termination by the Executive without
     Good Reason) after the Date of Termination and (B) the actual vested
     benefit, - if any, of the Executive under the Retirement Plan and the SERP,
     determined as of the Date of Termination (with the foregoing amounts to be
     computed on an actuarial present value basis, based on the assumption that
     the Executive's compensation in each of the five years (three years in the
     case of termination by the Executive without Good Reason) following such
     termination would have been that required


                                       7

<PAGE>


     by Section 3(a) and Section 3(b), and using actuarial assumptions no less
     favorable to the Executive than the most favorable of those in effect for
     purposes of computing benefit entitlements under the Retirement Plan and
     the SERP at any time from the day before the Effective Date) through the
     Date of Termination;

     (ii) for five (three years in the case of termination by the Executive
without Good Reason) years after the Executive's Date of Termination, or such
longer period as may be provided by the terms of the appropriate plan, program,
practice or policy, the Company shall continue all fringe and other benefits to
the Executive and/or the Executive's family at least equal to those which would
have been provided to them in accordance with the plans, programs, practices and
policies described in Section 3(d), (f) and (g) of this Agreement if the
Executive's employment had not been terminated (including without limitation
pursuant to the Split Dollar Agreement) or, if more favorable to the Executive,
as in effect generally at any time thereafter with respect to other peer
executives of the Company and its affiliated companies and their families,
provided, however, that if the Executive becomes reemployed with another
employer and is eligible to receive medical or other welfare benefits under
another employer-provided plan, the medical and other welfare benefits described
herein shall be secondary to those provided under such other plan during such
applicable period of eligibility, and for purposes of determining eligibility
(but not the time of commencement of benefits) of the Executive for retiree
benefits pursuant to such plans, practices, programs and policies, the Executive
shall be considered to have remained employed until five years (three years in
the case of termination by the Executive without Good Reason) after the Date of
Termination and to have retired on the last day of such period;

     (iii) the Company shall, at its sole expense as incurred, provide the
Executive with outplacement services the scope and provider of which shall be
selected by the Executive in the Executive's sole discretion (but the total cost
thereof shall not exceed $50,000); and

     (iv) for a period of five years following the Executive's termination, to
the extent not theretofore paid or provided, the Company shall timely pay or
provide to the Executive any other amounts or benefits required to be paid or
provided or which the Executive is eligible to receive under any plan, program,
policy or practice or contract or agreement of the Company and its affiliated
companies (such other amounts and benefits shall be hereinafter referred to as
the "Other Benefits").

     (b)  DEATH. If the Executive's employment is terminated by reason of the
Executive's death during the Employment Period, this Agreement shall terminate
without


                                       8

<PAGE>


further obligations to the Executive's legal representatives under this
Agreement, other than for payment of Accrued Obligations and the timely payment
or provision of Other Benefits. Accrued Obligations shall be paid to the
Executive's estate or beneficiary, as applicable, in a lump sum in cash within
30 days of the Date of Termination. With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 5(b) shall
include, without limitation, and the Executive's estate and/or beneficiaries
shall be entitled to receive, benefits at least equal to the most favorable
benefits provided by the Company and affiliated companies to the estates and
beneficiaries and peer executives of the Company and such affiliated companies
under such plans, programs, practices and policies relating to death benefits,
if any, as in effect with respect to other peer executives and their
beneficiaries at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive's estate and/or the
Executive's beneficiaries, as in effect on the date of the Executive's death
with respect to other peer executives of the Company and its affiliated
companies and their beneficiaries.

     (c)  DISABILITY. If the Executive's employment is terminated by reason of
the Executive's Disability during the Employment Period, this Agreement shall
terminate without further obligations to the Executive, other than for payment

disabled executives and/or their families in accordance with such plans,
programs, practices and policies relating to disability, if any, as in effect
generally with respect to other peer executives and their families at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive and/or the Executive's family, as in effect at any
time thereafter generally with respect to other peer executives of the Company
and its affiliated companies and their families.

     (d)  CAUSE. If the Executive's employment shall be terminated for Cause
during the Employment Period, this Agreement shall terminate without further
obligations to the Executive other than the obligation to pay to the Executive
(X) the Annual Base Salary through the Date of Termination, (Y) the amount of
any compensation previously deferred by the Executive, and (Z) Other Benefits,
in each case to the extent theretofore unpaid. In such case, all Accrued
Obligations shall be paid to the Executive in a lump sum in cash within 30 days
of the Date of Termination

     6.   NON-EXCLUSIVITY OF RIGHTS. Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company or any of its affiliated companies
and for which the


                                       9


<PAGE>


Executive may qualify, nor, subject to Section 10(f), shall anything herein
limit or otherwise affect such rights as the Executive may have under any
contract or agreement with the Company or any of its affiliated companies.
Amounts which are vested benefits or which the Executive is otherwise entitled
to receive under any plan, policy, practice or program of or any contract or
agreement with the Company or any of its affiliated companies at or subsequent
to the Date of Termination shall be payable in accordance with such plan,
policy, practice or program or contract or agreement except as explicitly
modified by this Agreement.

     7.   FULL SETTLEMENT; LEGAL FEES. The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and except as
specifically provided in Section 5(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment. The Company agrees to pay
promptly as incurred, to the full extent permitted by law, all legal fees and
expenses which the Executive may reasonably incur as a result of any contest
(regardless of the outcome thereof) by the Company, the Executive or others of
the validity or enforceability of, or liability or entitlement under, any
provision of this Agreement or any guarantee of performance thereof (whether
such contest is between the Company and the Executive or between either of them
and any third party, and including as a result of any contest by the Executive
about the amount of any payment pursuant to this Agreement), plus in each case
interest on any delayed payment at the applicable Federal rate ("Applicable
Federal Rate") provided for in Section 7872(f)(2)(A) of the Internal Revenue
Code of 1986, as amended (the "Code").

     8.   CONFIDENTIAL INFORMATION; NONCOMPETITION.

     (a)  CONFIDENTIAL INFORMATION. The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret, proprietary or confidential
information, knowledge or data relating to the Company or any of its affiliated
companies, and their respective businesses, which shall have been obtained by
the Executive during the Executive's employment by the Company or any of its
affiliated companies. During the period the Executive is employed with the
Company, and for a period of 24 months after termination of the Executive's
employment with the Company, the Executive shall not, without the prior written
consent of the Company or as may otherwise be required by law or legal process,
communication or divulge any such information, knowledge or data to anyone other
than the Company and those designated by it. The restrictions set forth in this
Section 8 will not apply to information that is generally known to the public or
in the trade, unless such knowledge results from an unauthorized disclosure by
the Executive or representatives of the Executive in violation of this
Agreement. This exception will not


                                       10

<PAGE>


affect the application of any other provisions of this Agreement to such
information in accordance with the terms of such provision. All documents and
tangible things embodying or containing confidential information are the
Company's exclusive property. The Executive will protect the confidentiality of
their content and will return all copies, facsimiles and specimens of them and
any other form of confidential information in the Executive's possession,
custody or control to the Company before leaving the employment with the
Company.

     (b)  NONCOMPETITON. In consideration of the benefits described in Section 5
and the Put Right set forth in Section 11, during the Executive's employment
with the Company, and for a period of 36 months thereafter, the Executive shall
not, directly or indirectly, engage, participate or invest in or be employed by
any business which is engaged in the scientific and clinical laboratory research
distribution business in the United States. The foregoing restriction shall
apply regardless of the capacity in which the Executive engages or engaged,
participates or participated, or invests or invested in or is or was employed by
a given business, whether as owner, partner, shareholder, consultant, agent,
employee, co-venturer or otherwise. The provisions of this Section 8(b) shall
not prevent the Executive from acquiring or holding publicly traded stock or
other publicly traded securities of a business, so long as the Executive's
ownership does not exceed 2 percent of the outstanding securities of such
company of the same class as those held by the Executive or from engaging in any
activity or having an ownership interest in any business that is reviewed by the
Board of Directors. The Executive understands that the restrictions set out in
this Section 8(b) are intended to protect the Company's interest in its secret,
proprietary or confidential information and established customer relationships
and goodwill, and agrees that such restrictions are reasonable and appropriate
for this purpose.

     (c)  INJUNCTIVE RELIEF. The Executive agrees that it would be difficult to
measure any damages caused to the Company that might result from any breach by
the Executive of the promises set forth in this Agreement, and that in any event
money damages would be an inadequate remedy for any such breach. Accordingly,
the Executive agrees that in the case of breach, or proposed breach, of any
portion of this Agreement, the Company shall be entitled, in addition to all
other remedies that it may have, to an injunction or other appropriate equitable
relief to restrain any such breach without showing or proving any actual damage
to the Company. However, in no event shall an asserted violation of the
provisions of this Section 8 constitute a basis for deferring or withholding any
amounts otherwise payable to the Executive under this Agreement.

     9.   SUCCESSORS. This Agreement is personal to the Executive and without he
prior written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution. This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives. This Agreement


                                       11

<PAGE>


shall inure to the benefit of and be binding upon the Company and its successors
and assigns. The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company to assume expressly and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor to its business and/or assets as aforesaid which
assumes and agrees to perform this Agreement by operation of law, or otherwise.

     10.  MISCELLANEOUS.

     (a)  GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, without reference to
principles of conflict of laws. The captions of this Agreement are not part of
the provisions hereof and shall have no force or effect. This Agreement may not
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

     (b)  NOTICES. All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party or by registered

<PAGE>


     (d)  WITHHOLDING. The Company may withhold from any amounts payable under
this Agreement such Federal, state, local or foreign taxes as shall be required
to be withheld pursuant to any applicable law or regulation.

     (e)  WAIVER. The Executive's or the Company's failure to insist upon strict
compliance with any provision hereof or any other provision of this Agreement or
the failure to assert any right the Executive or the Company may have hereunder,
including, without limitation, the right of the Executive to terminate
employment for Good Reason, shall not be deemed to be a waiver of such provision
or right or any other provision or right of this Agreement.

     (f)  ENTIRE AGREEMENT. From and after the Effective Date this Agreement
shall supersede any other employment agreement between the parties with respect
to the subject matter hereof. For the avoidance of doubt, this Agreement shall
not supersede the Split Dollar Agreement, nor shall it amend the Split Dollar
Agreement except to the extent specifically provided herein, nor shall it amend,
modify or alter in any way any existing agreement between the Company and the
Executive regarding any equity interest in the Company, regardless of form.

     11.  PUT/CALL RIGHT.

     (a)  EXECUTIVE'S PUT. In partial consideration of the Executive's
noncompetition covenant pursuant to Section 8(b), at any time following the
Effective Date, the Executive and/or any Permitted Transferee (as defined below)
shall have the right (the "Put Right"), exercisable by delivery of a written
notice (the "Put Notice") to the Company, to require the Company to purchase
all, but not less than all, of the 51,667 Executive Performance Options (the
"Put Options") granted to the Executive pursuant to the Fisher Scientific
International Inc. 1998 Equity and Incentive Plan (the "1998 Option Plan"), for
an aggregate purchase price (the "Put Price") of $5,000,000 in cash, subject to
the provisions of this Section 11. Following receipt of the Put Notice, the
Company shall be required to pay the Put Price to the Executive or the Permitted
Transferee, as applicable, upon the second business day following the first
anniversary of the date the Put Notice is received by the Company; PROVIDED,
that if on such second business day, the Executive is a "covered employee" whose
compensation is subject to the limitation on deductibility imposed by Section
162(m) of the Code, such payment shall be delayed until the first date on which
the Executive is no longer such a "covered employee." For purpose of this
Section 11, "Permitted Transferee" shall mean any heir, executor, administrator,
testamentary trustee, legatee or beneficiary of the Executive and any party who
is a legitimate transferee of the Put Options in accordance with the instruments
governing their transfer. The Company shall pay the Executive interest on the
$5,000,000 cash payment due to the Executive following exercise of the Put Right
at a rate equal to the prime rate published by The Chase Manhattan Bank on the
business day nearest to the date on which the Put Right is exercised, compounded
daily. Such interest

                                       13

<PAGE>


shall accrue from the date of exercise until the date the $5,000,000 payment is
made to the Executive, and shall be paid to the Executive concurrently with such
$5,000,000 payment.

     (b)  COMPANY'S CALL RIGHT. Upon termination of the Executive's employment
with the Company for any reason (a "Call Event"), the Company shall have the
right (the "Call Right"), exercisable by delivery of a written notice (the "Call
Notice") to the Executive and any Permitted Transferees who then own any Put
Options within a period of 180 days after the date of occurrence of the Call
Event (subject to extension for up to 12 months in the event the Company is
legally prohibited or contractually prohibited, by virtue of its debt or other
obligations, from exercising its Call Rights) (the "Call Notice Period"), to
require the Executive and any such Permitted Transferees to sell all, but not
less than all, of the Put Options owned by the Executive and such Permitted
Transferees on the date of occurrence of the Call Event at an aggregate price
equal to the Put Price, allocated among the Executive and such Permitted
Transferees (if any) in the same proportions as their ownership of the Put
Options. Upon receipt of such notice the Executive and any such Permitted
Transferees shall sell such Put Options, subject to the terms hereof.

     (c)  CLOSING. The closing of the acquisition by the Company of Put Options
following exercise of the Put Right or the Call Right shall take place at the
principal office of the Company on the tenth business day after the date of the
Put Notice or the Call Notice. At such closing, the Company shall pay the Put
Price by wire transfer to the account or accounts designated by the Executive or
Permitted Transferee, as applicable, in writing to Company or, if the Executive
or Permitted Transferee, as applicable, fails to designate any such account, the
Company shall deliver a certified check or checks in the amount of the
applicable Put Price to the Executive or such Permitted Transferee, as
applicable, in each case against delivery of duly endorsed certificates
representing such Put Options (to he extent issued in certificated form).

     IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand
and, pursuant to the authorization from its Board of Directors, the Company has
caused this Agreement to be executed in its name on its behalf, all as of the
day and year first above written.
