                              RETENTION AGREEMENT

     AGREEMENT by and between Mallinckrodt Inc.,  a New York corporation (the
"Company") and __________ (the "Executive"), dated as of June __, 2000, but
effective as of the Effective Date (as hereinafter defined).

                              W I T N E S S E T H

     WHEREAS, Executive is employed by the Company; and

     WHEREAS, the Company is entering into an agreement and plan of merger among
Tyco Acquisition Corp. VI (NV) ("Tyco (NV)"),  a Nevada corporation and a
direct, wholly-owned subsidiary of Tyco International Ltd. ("Tyco"), a Bermuda
company, EMV Merger Corp. ("Merger Sub"), a New York corporation and a direct,
wholly-owned subsidiary of Tyco (NV), and the Company, providing for the merger
(the "Merger") of Merger Sub with and into the Company, pursuant to which the
Company will become a direct, wholly-owned subsidiary of Tyco (NV); and

     WHEREAS, Executive performs services of a unique nature for the Company
that are irreplaceable; and

     WHEREAS, Executive's performance of such services to a competing business
will result in significant and irreparable harm to the Company; and

     WHEREAS, the Company has determined that it is imperative that the Company
be able to rely on Executive to continue in his position in order to assure
continuity of management at the Company, to assure customers and other Company
employees of stability at the Company and to provide critical assistance in the
management and operation of the Company; and

     WHEREAS, the Company has determined to offer Executive the benefits
described in this Agreement to provide an incentive to encourage Executive to
remain in the employ of the Company so that the Company may receive his
continued dedication and assure the continued availability of his advice and
counsel and to assure that he will not provide services for a competing business
in accordance with the terms hereof; and

     WHEREAS, Executive has agreed to serve the Company pursuant to the terms
and conditions hereinafter set forth.

     NOW, THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, the Company and Executive hereby agree as follows:

<PAGE>

                                                                               2

1. Definitions.

          As used in this Agreement, the following terms shall have the
respective meanings set forth below:

          (a)   "Business Combination" means any merger, consolidation, share
exchange or similar form of corporate reorganization of the Company or the
direct or indirect sale of all of substantially all of the assets of the
Company.

          (b)   "Cause" means (i) the willful and continued failure of Executive
substantially to perform his duties with the Company (other than any failure due
to physical or mental incapacity) which remains uncured for a period of ten (10)
days after a demand for substantial performance is delivered to him by the Board
which specifically identifies the manner in which the Board of Directors of the
Company (the "Board") believes he has not substantially performed his duties or
(ii) willful misconduct materially and demonstrably injurious to the Company.
No act or failure to act by Executive shall be considered "willful" unless done
or omitted to be done by him not in good faith and without reasonable belief
that his action or omission was in the best interest of the Company.  The
unwillingness of Executive to accept any condition or event which would
constitute Good Reason under Section 1(g) may not be considered by the Board to
be a failure to perform or misconduct by Executive.  Notwithstanding the
foregoing, Executive shall not be deemed to have been terminated for Cause for
purposes of this Agreement unless and until there shall have been delivered to
him a copy of a resolution, duly adopted by a vote of three-quarters (3/4) of
the entire Board at a meeting of the Board called and held (after reasonable
notice to Executive and an opportunity for Executive and his counsel to be heard
before the Board) for the purpose of considering whether Executive has been
guilty of such a willful failure to perform or such willful misconduct as
justifies termination for cause hereunder, finding that in the good faith
opinion of the Board Executive has been guilty thereof and specifying the
particulars thereof.  The Company must notify Executive of an event constituting
Cause within ninety (90) days following the Board's knowledge of its existence
or such event shall not constitute Cause under this Agreement.

          (c)   "Effective Date" has the meaning specified in Section 2.

          (d)   "Company" means Mallinckrodt Inc., a New York corporation, and,
the successor of, or transferee of assets from, the Company in connection with
any Business Combination, including Merger Sub.

          (e)   "Date of Termination" means (1) the effective date on which
Executive's employment by the Company terminates as specified in a Notice of
Termination by the Company or Executive, as the case may be, or (2) if
Executive's employment by the Company terminates by reason of death, the date of
death of Executive. Notwithstanding the previous sentence, (i) if Executive's
employment is terminated for Disability (as defined in Section 1(f)), then such
Date of Termination shall be no earlier than thirty (30) days following the date
on which a Notice of Termination is received, and (ii) if Executive's employment
is terminated by the Company other

than for Cause, then such Date of Termination shall be no earlier than thirty
(30) days following the date on which a Notice of Termination is received.

          (f)   "Disability" means physical or mental incapacity qualifying
Executive for long-term disability under the Company's long-term disability
plan.

          (g)   "Good Reason" means, without Executive's express written
consent, the occurrence of any of the following events:

          (1)   (i) the assignment to Executive of any duties or
responsibilities (including reporting responsibilities) inconsistent in any
material and adverse respect with Executive's duties and responsibilities with
the Company immediately prior to the Effective Date (including any material and
adverse diminution of such duties or responsibilities); provided, however, that
Good Reason shall not be deemed to occur upon a change in duties or
responsibilities that is solely and directly a result of the Company no longer
being a publicly traded entity, and does not involve any other event set forth
in this paragraph (g), (ii) a material and adverse change in Executive's titles
or offices with the Company as in effect immediately prior to the Effective Date
or (iii) any attempted removal or involuntary termination of Executive by the
Company otherwise than as expressly permitted by this Agreement pursuant to a
Nonqualifying Termination (or any purported termination of employment which is
not effected by a Notice of Termination, which termination shall not be
effective);

          (2)   a reduction by the Company in Executive's rate of annual base
salary or target annual bonus opportunity as in effect immediately prior to the
Effective Date or as the same may be increased from time to time thereafter;

          (3)   any requirement of the Company that Executive (i)
notwithstanding Executive's objection, be based anywhere more than fifty (50)
miles from the location where Executive's employment is located at the time of
the Effective Date or (ii) travel on Company business to an extent substantially
greater than the travel obligations of Executive immediately prior to the
Effective Date;

          (4)   the failure of the Company to (i) continue in effect any
employee benefit plan or compensation plan in which Executive is participating
immediately prior to the Effective Date (including the taking of any action by
the Company which would adversely affect Executive's participation in or
materially reduce Executive's benefits under any such plan), unless Executive is
permitted to participate in other plans providing Executive with substantially
comparable benefits, (ii) provide Executive and Executive's dependents with
welfare benefits in accordance with the most favorable plans, practices,
programs and policies of the Company and its affiliated companies in effect for
Executive immediately prior to the Effective Date or provide substantially
comparable benefits at a substantially comparable cost to Executive, (iii)
provide fringe benefits in accordance with the most favorable plans, practices,
programs and policies of the Company and its affiliated companies in effect for
Executive immediately prior to the Effective Date, or provide substantially
comparable fringe benefits, or (iv) provide Executive with paid vacation in
accordance with the most favorable plans, policies, programs and practices
<PAGE>

                                                                               4

of the Company and its affiliated companies as in effect for Executive
immediately prior to the Effective Date (including crediting Executive with all
service credited to Executive for such purpose prior to the Effective Date),
unless the failure to provide such paid vacation is a result of a policy
uniformly applied by the entity acquiring the Company to its employees; or

          (5)   the failure of the Company to obtain the assumption agreement
from any sucessor as contemplated in Section 10(b)

          Notwithstanding the foregoing, an isolated and inadvertent action
taken in good faith and which is remedied by the Company within ten (10) days
after receipt of notice thereof given by Executive shall not constitute Good
Reason.

          Any event or condition described in Section 1(g)(1) through(4) which
occurs prior to the Effective Date, but which Executive reasonably demonstrates
was done at the request of Tyco (NV) or Tyco or their respective affiliates
shall constitute Good Reason following the Effective Date for purposes of this
Agreement notwithstanding that it occurred prior to the Effective Date.

          (h)   "Nonqualifying Termination" means a termination of Executive's
employment (1) by the Company for Cause, (2) by Executive for any reason other
than Good Reason, (3) as a result of Executive's death, (4) by the Company due
to Executive's Disability, unless within thirty (30) days after Notice of
Termination is provided to Executive pursuant to Section 11 following such
absence Executive shall have returned to performance of Executive's duties on a
full-time basis, or (5) as a result of Executive's Retirement.

          (i)   "Notice of Termination" means notice of the Date of Termination
as described in Section 11(b).

          (j)   "Retirement" means termination of employment by either Executive
or the Company (other than for Cause) on or after Executive's normal retirement
date under the terms of the Retirement Plan (other than if any such Retirement
also constitutes Good Reason).

          (l)   "Retirement Plan" means The Mallinckrodt Retirement Plan or any
successor or substitute plan or plans of the Company, as in effect immediately
prior to the Effective Date.

          (m)   "Subsidiary" means any corporation or other entity in which the
Company has a direct or indirect ownership interest of 50% or more of the total
combined voting power of the then outstanding securities of such corporation or
other entity entitled to vote generally in the election of directors.

          (k)   "Termination Period" the period of time beginning with the
Effective Date and ending on the earliest to occur of (I) Executive's death and
(II) three (3) years following such Effective Date.
<PAGE>

                                                                               5

2. Effective Date.

          The "Effective Date" of this Agreement shall be the date and time
immediately prior to the consummation of the Merger.  In the event the Merger is
not consummated for whatever reason, this Agreement shall be null and void and
of no force and effect, and shall have no impact or effect with respect to any
other agreement by and between Executive and the Company in effect prior to the
date this Agreement was executed.

          Notwithstanding anything to the contrary in this Agreement, if
Executive's employment is terminated prior to the Effective Date and Executive
reasonably demonstrates that such termination was at the request of Tyco (NV) or
Tyco or their respective affiliates, and the Merger is thereafter consummated,
then for all purposes of this Agreement "Effective Date" shall mean the date
immediately prior to the date of such termination of employment.

3. Stock Options.

          To the extent not otherwise provided in the Company's stock option and
other equity incentive plans and/or stock option or equity incentive awards, any
unvested stock options or other unvested equity incentive awards held by
Executive as of the Effective Date shall become fully vested and exercisable
upon the Effective Date.

4. Retention/Non-Competition Payments.

          In recognition of Executive's agreement to remain with the Company and
not seek employment elsewhere following the Effective Date and in consideration
of Executive's agreement contained herein regarding non-competing employment,
the Company agrees to make the following payments and to afford the following
benefits to Executive:

          A.    If either (I) Executive continues to be employed by the Company
on the second anniversary of the Effective Date or (II) on or before the second
anniversary of the Effective Date Executive's Employment is terminated other
than by reason of a Nonqualifying Termination, the Company shall make the
payments and afford the benefits to Executive as set forth in this Section 4A.
For purposes of this Section 4A, "Determination Date" means the second
anniversary of the Effective Date, if the payments and benefits are due under
clause (I) above, and the Date of Termination, if the payments and benefits are
due under clause (II) above.

          The Company shall pay to Executive (or Executive's beneficiary or
estate) within five (5) days following the Determination Date, as compensation
for services rendered to the Company, a lump-sum cash amount equal to three (3)
(the "Payment Multiple") times the sum of (A) Executive's annual rate of base
salary from the Company and its affiliated companies in effect immediately prior
to the Determination Date (not taking into account any reductions which would
constitute Good Reason) plus (B) Executive's target awards or target bonuses
under the Company's annual incentive compensation plans (e.g., the Company's
Executive Incentive Compensation Plan and Management Incentive Compensation
Plan, or any successor plans) for the fiscal year of the Company in which the
Effective Date occurs or, if greater, Executive's
<PAGE>

                                                                               6

target awards or target bonuses under such annual compensation plans for the
fiscal year immediately preceding the fiscal year in which the Effective Date
occurs; and provided that any amount paid pursuant to this Section 4A shall
offset any other amount of severance relating to salary or bonus continuation to
be received by Executive upon termination of employment of Executive under any
other severance plan or policy or the severance provisions of any employment
agreement of the Company (but not under any Company bonus, incentive or other
compensatory arrangement of the Company including, without limitation, the
Company's Executive Incentive Compensation Plan, Management Incentive
Compensation Plan, Long-Term Incentive Plan or any successor plans thereto).

          B.    In addition, if during the Termination Period Executive's
employment is terminated other than by reason of a Nonqualifying Termination,
the Company shall make the payments and afford the benefits to Executive as set
forth in this Section 4B.

          (a)   The Company shall pay to Executive (or Executive's beneficiary
or estate) within five (5) days following the Date of Termination, as
compensation for services rendered to the Company:

          (1)   a lump-sum cash amount equal to the sum of Executive's unpaid
base salary from the Company and its affiliated companies through the Date of
Termination (without taking into account any reduction of base salary
constituting Good Reason) plus any bonus payments which have become payable, to
the extent not theretofore paid; and

          (2)   (A) to the extent not paid under the terms of such annual
incentive compensation plan, a lump-sum cash amount equal to Executive's target
awards or target bonuses under the Company's annual incentive compensation plans
(e.g., the Company's Executive Incentive Compensation Plan and Management
Incentive Compensation Plan, or any successor plans) for the fiscal year in
which the Date of Termination occurs, reduced pro rata for that portion of the
fiscal year not completed as of the end of the month in which such Date of
Termination occurs, and (B) to the extent not paid under the terms of any long-
term incentive plan established by the Company, a lump sum cash payment equal to
Executive's full target award or target bonus under such long-term incentive
plan with respect to the then applicable performance cycle or performance
period.

          (b)   If (x) Executive is 55 or older on the Date of Termination,
until the occurrence of Executive's death1/1/ or (y) Executive is under 55 on
the Date of Termination, for a period of twenty-four (24) months, the Company
shall provide Executive (and Executive's dependents, if applicable) with the
same level of medical, dental, accident, disability and life insurance benefits
(including participation in the Company's Executive life insurance program, if
applicable) upon substantially the same terms and conditions (including cost of
coverage) as existed immediately prior to Executive's Date of Termination (or,
if more favorable to Executive, as such benefits and terms and conditions
existed immediately prior to the Effective Date);

                                                                               7

provided, that, if Executive cannot continue to participate in the Company plans
providing such benefits, the Company shall otherwise provide such benefits on
the same after-tax basis as if continued participation had been permitted.
Notwithstanding the foregoing, if Executive is under 55 on the Date of
Termination and becomes reemployed with another employer and is eligible to
receive welfare benefits from such employer (other than life insurance benefits
to which this sentence shall not apply) that are comparable or more favorable to
Executive than the Company provided welfare benefits, then the Company's
obligation to continue to provide Executive with welfare benefits (other than
life insurance benefits) of the type so obtained by Executive will thereupon
cease./2/

          [(c)  Executive shall (A) be credited with three (3) additional years
of credited service for purposes of calculating benefits under the Company's
Supplemental Executive Retirement Plans (collectively, the "SERP") and (B) if
Executive is, on the Date of Termination, age 55 or older, be entitled to
receive an unreduced normal retirement benefit under the SERP commencing upon
the Date of Termination (without regard to Executive's years of service with the
Company) (or, if later, the date on which Executive becomes 55)]/3/

          (d)   Executive shall be entitled to (1) retain all rights to
indemnification under applicable law or under the Company's certificate of
incorporation or by-laws as in effect as of the Effective Date or Executive's
Date of Termination, whichever is more favorable to Executive; (2) continue to
be covered by Company provided directors and officers liability insurance at the
level in effect immediately prior to the Effective Date or the Date of
Determination, which ever is more favorable to Executive, for the period of
years that corresponds with the Payment Multiple and throughout the applicable
statute of limitations period; and (3) be entitled to either, at the election of
Executive, (i) a cash payment equal to $75,000 or (ii) Company provided
executive outplacement services for a period of years that corresponds to the
Payment Multiple, not to exceed $75,000.

          C.    If during the Termination Period the employment of Executive
shall terminate by reason of a Nonqualifying Termination, then the Company shall
pay to Executive within five (5) days following the Date of Termination a lump
sum cash amount equal to the sum of Executive's unpaid base salary from the
Company through the Date of Termination plus any bonus payments which have
become payable, to the extent not theretofore paid.

5. Certain Additional Payments by the Company.

          (a)   Anything in this Agreement to the contrary notwithstanding, in
the event it shall be determined that any payment or distribution by the Company
or its affiliated companies (or one or more trusts established by the Company or
its affiliates for the benefit of its

employees) or by any other party in connection with a change in control to or
for the benefit of Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this Section
5) (a "Payment") would be subject to the excise tax imposed by Section 4999 of
the Code, or any interest or penalties are incurred by Executive with respect to
such excise tax (such excise tax, together with any such interest and penalties,
are hereinafter collectively referred to as the "Excise Tax"), then Executive
shall be entitled to receive an additional payment (a "Gross-Up Payment") in an
amount such that after payment by Executive of all taxes (including any interest
or penalties imposed with respect to such taxes) including, without limitation,
any income and employment taxes (and any interest and penalties imposed with
respect thereto) and Excise Tax, imposed upon the Gross-Up Payment, Executive
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments. For purposes of determining the amount of the Gross-Up Payment,
Executive shall be deemed to pay federal income taxes at the highest marginal
rates of federal income taxation for the calendar year in which the Gross-Up
Payment is to be made and applicable state and local income taxes at the highest
marginal rate of taxation for the calendar year in which the Gross-Up Payment is
to be made, net of the maximum reduction in federal income taxes which could be
obtained from deduction of such state and local taxes.

          (b)   All determinations required to be made under this Section 5,
including whether and when a Gross-Up Payment is required and the amount of such
Gross-Up Payment and the assumptions to be utilized in arriving at such
determination (collectively, the "Determination"), shall be made by
PricewaterhouseCoopers LLP (the "Accounting Firm"). All fees and expenses of the
Accounting Firm shall be borne solely by the Company and the Company shall enter
into any agreement requested by the Accounting Firm in connection with the
performance of the services hereunder. Upon the request of Executive, the
Company shall make representatives of the Accounting Firm available to Executive
and Executive's representatives to discuss the basis for the Determination of
the Accounting Firm made pursuant to this Section 5. The Gross-Up Payment under
this Section 5 should be made within thirty (30) days of any Payment. As a
result of the uncertainty in the application of Section 4999 of the Code at the
time of the Determination, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment") or Gross-Up
Payments will be made by the Company which should not have been made
("Overpayment"), consistent with the calculations required to be made hereunder.
In the event that Executive thereafter is required to make payment of any
additional Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment (together with an
amount, on an after-tax basis, equal to any interest and penalties incurred by
Executive with respect to any such Underpayment) shall be promptly paid by the
Company to or for the benefit of Executive. In the event the amount of the
Gross-Up Payment exceeds the amount necessary to reimburse Executive for his
Excise Tax, the Accounting Firm shall determine the amount of the Overpayment
that has been made and any such Overpayment (together with interest at the
rate provided in Section 1274(b)(2) of the Code) shall be promptly paid by
Executive to or for the benefit of the Company; provided that to the extent
such Overpayment had theretofore been paid to the Internal Revenue Service or
other applicable taxing authority, Executive's repayment obligation of such
amount (with interest) hereunder shall only apply to the extent Executive
<PAGE>

                                                                               9

receives a refund of such amount from the Internal Revenue Service or other
applicable taxing authority and Executive's repayment obligation shall be
limited to the amount of any such refund. Executive shall cooperate with any
reasonable requests by the Company in connection with any contests or disputes
with the Internal Revenue Service in connection with the Excise Tax and shall be
reimbursed by the Company, on an after-tax basis, for all costs, expenses,
interest and penalties incurred by Executive in connection with any such contest
or dispute.

6. Withholding Taxes.

          The Company may withhold from all payments due to Executive (or his
beneficiary or estate) hereunder all taxes which, by applicable federal, state,
local or other law, the Company is required to withhold therefrom.

7. Non-competition Agreement.

          For a period of two years following Executive's termination of
employment with the Company (the "Non-compete Period"), other than (i) by reason
of a Nonqualifying Termination or (ii) if such termination occurs after the
Termination Period, in consideration of, and conditioned upon, the payment to
Executive of the amounts provided in Section 4 of this Agreement, Executive
shall not serve as an employee, consultant, owner, officer or director of any
organization or business entity which is manufacturing, distributing or selling
one or more "Competing Products" (as hereinafter defined) in a manner which is
materially competitive with the Company's manufacturing or selling activities in
the same geographic area with respect to its competing or similar products (such
organization or business entity, a "Competitor"). Notwithstanding the foregoing,
it shall not be a breach of this Section 7 if, after the termination of
Executive's employment, Executive is employed by a Competitor so long as
Executive does not work or make policy for, oversee in fact, consult with, or
provide information to, any subsidiary, division or other organizational unit of
such Competitor which manufactures or sells such Competitive Products.

          For purposes of this Agreement, "Competing Products" shall mean (i) if
the Executive's principal employment responsibilities relate to the Company's
respiratory care operations, Company products, as of the Effective Date,
relating to oxygen monitoring through pulse oximetry technology, critical care
and alternate care ventilators and disposable airway management devices; (ii) if
Executive's principal employment responsibilities relate to the Company's
medical imagining operations, Company products, as of the Effective Date,
relating to contrast agents and diagnostic radio pharmaceuticals, (iii) if
Executive's principal employment responsibilities relate to the Company's
pharmaceutical operations, Company products, as of the Effective Date, relating
to Acetaminophen, medicinal narcotics and combinations thereof and (iv) if
Executive's principal employment responsibilities relate to the management of
the Company as a whole, all such Company products.

8. Reimbursement of Expenses.

          If any contest or dispute shall arise under this Agreement involving
termination of Executive's employment with the Company or involving the failure
or refusal of the Company to perform fully in accordance with the terms hereof,
the Company shall reimburse Executive, on a current basis, for all reasonable
legal fees and expenses, if any, incurred by Executive in connection with such
contest or dispute regardless of the result thereof.  Executive agrees that in
the event it is determined in an arbitration proceeding that Executive's basis
for a contest or dispute was frivolous and not advanced in good faith, Executive
shall be obligated to return to the Company any such reimbursed legal fees and
expenses within sixty (60) days following the determination.

9. Scope of Agreement.

          Nothing in this Agreement shall be deemed to entitle Executive to
continued employment with the Company or its Subsidiaries.

10. Successors; Binding Agreement.

          (a)   This Agreement shall not be terminated by any Business
Combination. In the event of any Business Combination, the provisions of this
Agreement shall be binding upon the surviving or resulting corporation or the
person or entity to which such assets are transferred.

          (b)   The Company agrees that, for so long as it has any obligations
under this Agreement, concurrently with any Business Combination it will cause
any successor or transferee (if other than the Company) unconditionally to
assume, by written instrument delivered to Executive (or his beneficiary or
estate), all of the obligations of the Company hereunder. Failure of the Company
to obtain such assumption prior to the effectiveness of any Business Combination
shall be a breach of this Agreement and shall constitute Good Reason hereunder
and shall entitle Executive to compensation and other benefits from the Company
in the same amount and on the same terms as Executive would be entitled
hereunder if Executive's employment were terminated following the Effective Date
other than by reason of a Nonqualifying Termination. For purposes of
implementing the foregoing, the date on which any such Business Combination
becomes effective shall be deemed the date Good Reason occurs, and shall be the
Date of Termination if requested by Executive.

          (c)   This Agreement shall inure to the benefit of and be enforceable

                             AMENDMENT NUMBER ONE
                                    to the
                     EXECUTIVE INCENTIVE COMPENSATION PLAN
                                FOR FISCAL 2000

          The Executive Incentive Compensation Plan for Fiscal 2000 (the
"Plan"), is hereby amended, effective as of June 15, 2000, as set forth below.

          Capitalized terms used herein without definition shall have the
respective meanings set forth in the Plan.

          1.   Section 4.  Target Incentive Awards.
               -----------------------------------

          The second to last sentence of Section 4 shall be amended by replacing
the phrase "by comparing the average of the high and low price of the Company's
common stock, as reflected on the New York Stock Exchange Composite transactions
tape ("NYSE Tape") during the last fifteen (15) New York Stock Exchange trading
dates of Fiscal 2000" with the phrase "by comparing $27.50 (representing the
closing price of the Company's common stock, as reflected on the New York Stock
Exchange Composite transactions tape ("NYSE Tape") on June 15, 2000) (the
"Fiscal 2000 Price")"

          A new sentence shall be inserted before the last sentence of Section 4
and read as follows:

     "Notwithstanding the foregoing, in the event a Change in Control occurs
     during the Company's Fiscal 2000 or during the Company's fiscal year
     beginning July 1, 2000 as a result of negotiations which commenced during
     Fiscal 2000 (a "Qualifying Change of Control") then the Fiscal 2000 Price
     shall be deemed to be the greater of (x) $27.50 and (y) the Change of
     Control Price (as defined below)."

          The following provisions shall be added to the end of Section 4:

     "Change of Control Price" shall mean the amount of consideration per share
     paid to the Company's shareholders in connection with the Change in
     Control.  If the consideration paid to the Company's shareholders in
     connection with the Change of Control consists in whole or in part of other
     securities or other property or assets then the value of such securities or
     other property or assets shall be the fair market value of such securities
     or other property or assets as determined on the day prior to the
     consummation of the Change in Control.  If such securities are publicly
     traded securities of another corporation ("Acquiror Stock") the fair market
     value of such securities shall be the volume-weighted average of the per
     share selling price of Acquiror Stock for the five consecutive trading days
     ending on the second trading day prior to the consummation of the Change of
     Control (the "Trading Period") on the Composite Tape of the principal
     national securities exchange on which such shares of Acquiror Stock are
     listed or, if no Composite Tape exists for such national securities
     exchange on such date, then on the principal national securities exchange
     on which such shares are listed or admitted to trading, or if such shares
     are not listed or admitted on a national securities exchange, then by the
     average arithmetic means of the per share closing bid price and per share
     closing asked price of
<PAGE>

     such share of Acquiror Stock during the Trading Period as quoted on the
     National Associate of Securities Dealers Automated Quotation system (or
     such market in which such prices are regularly quoted). If such securities
     are not publicly traded securities or if the consideration paid is other
     property or assets, then the fair market value of such securities, other
     property or assets shall be as determined by the Board of Directors in good
     faith in consideration of all relevant factors, including any recent
     trading price of the Company's common stock, and based upon the advice of
     the investment bank or other third party financial expert assisting the
     Company for purposes of evaluating the Change of Control transaction.

          In the event an incentive award is paid to a participant hereunder
     prior to the consummation of a Qualifying Change of Control and a
     Qualifying Change of Control subsequently occurs, then the amount of the
     participant's Target Award shall be recalculated based upon the Change of
     Control Price and if the amount of the Target Award, as recalculated, is
     greater, the participant shall be entitled to a supplemental payment
     hereunder based upon such recalculated Target Award. Any such supplemental
     payment shall be paid to the participant in cash within 30 days following
     the consummation of a Qualifying Change of Control.

          2.   Section 8.  Change in Control.
               -----------------------------

          (a)  The definition of "Good Reason" set forth in Section 8(b) of the
Plan is amended by deleting the last sentence thereof which currently reads "The
participant must notify the Company of an event constituting Good Reason within
ninety (90) days following his or her knowledge of its existence or such event
shall not constitute Good Reason under the Plan."

          (b)  The definition of "Cause" set forth in Section 8(c) of the Plan
is amended to include the phrase "which remains uncured for a period of ten (10)
days" immediately following the parenthetical "(other than any failure due to
physical or mental incapacity)".

          3.  The validity, interpretation, and enforcement of this amendment
shall be governed by the law of the State of New York. The invalidity or
unenforceabililty of any provision of this amendment shall not affect the
validity or enforceabililty of any other provision of this amendment or of the
Plan, as amended hereby, which other provisions shall remain in full force and
effect.
