                            PERSONAL AND CONFIDENTIAL

Dear Paul:

                  Last October you and Bristol-Myers Squibb Company
("Bristol-Myers Squibb") executed a letter agreement dated October 12, 2000 (the
"2000 Agreement") that described the bonus payments and other incentives that
you would receive in the event that Zimmer, Inc. ("Zimmer") was sold to a
third-party entity on or before September 30, 2001. It now appears possible that
Bristol-Myers Squibb may divest its interest in Zimmer through a "spin-off"
transaction involving the distribution of Zimmer stock to Bristol-Myers Squibb
shareholders (the "Spin-Off"). The Spin-Off may be preceded by a public offering
of Zimmer shares (the "IPO"). During the divestiture process, we believe that
operating the Zimmer business as usual is in the best interests of Bristol-Myers
Squibb, Zimmer and its employees. To provide assurance to you and to help ensure
that the Zimmer business is managed and operated efficiently and effectively
both before and after the divestiture, Bristol-Myers Squibb and Zimmer wish to
offer you the incentives described in this letter. If these incentives are
satisfactory and you wish to participate, please sign and return this letter in
the manner described on the last page of this letter.

                  The terms and conditions of this letter agreement will apply
in the event of an IPO or Spin-Off of Zimmer that occurs on or before September
30, 2001 and, with respect to payments and benefits contingent upon a Spin-Off,
the consummation of the Spin-Off on or before March 31, 2002. In the event of a
disposition of Zimmer which is not an IPO or Spin-Off occurring on or before
September 30, 2001 and, with respect to payments and benefits contingent upon a
Spin-Off, if the Spin-Off is not completed on or before March 31, 2002, the
terms and conditions of this letter agreement will terminate and will not apply.
Please note that if Zimmer is sold to a third party entity on or before
September 30, 2001, you will receive the bonus payments and other incentives
subject to the conditions described in the 2000 Agreement.

                  As a member of the Zimmer management team, you are expected to
carry out the duties and responsibilities of your job during the coming months.
In addition, your assistance

will be necessary to complete the divestiture process. For your extra efforts
and cooperation in helping Bristol-Myers Squibb and Zimmer during this period,
you will be provided with the following incentives, subject to all of the terms
and conditions of this letter agreement:

1. SPECIAL STOCK OPTION AWARD. Effective on the date of the Spin-Off or, if it
occurs first, the IPO (the "Effective Date"), you will receive an option to
purchase shares of Zimmer stock with an economic value at the time of grant of
$175,000 using a generally accepted valuation methodology. This option will be
issued under a new option and equity compensation plan (the "Zimmer Stock
Incentive Plan") that will be adopted by Zimmer's Board of Directors. Your
option will vest in equal installments over a period of four years provided that
you remain employed with Zimmer during that time, or as provided otherwise under
the Zimmer Stock Incentive Plan. The exercise price will equal the fair market
value of Zimmer stock at the time the option is granted.

2. SPECIAL RESTRICTED STOCK AWARD. As of the Effective Date, you will receive a
grant of Zimmer restricted stock with a value (determined as if no restrictions
applied) of $60,000. The restricted stock will vest in three equal installments
on the third, fourth and fifth anniversaries of the grant of the award provided
that you remain employed with Zimmer during that time. Any dividends that are
payable on Zimmer stock will be paid to you on this restricted stock on a
current basis. This restricted stock will also be issued under the Zimmer Stock
Incentive Plan.

3. CONVERSION OF OUTSTANDING STOCK OPTIONS. Any Bristol-Myers Squibb stock
options granted to you prior to the Effective Date (including, but not limited
to, the options awarded to you on January 3, 2000 pursuant to a 50% reduction in
target cash bonus under the Bristol-Myers Squibb Company Performance Incentive
Plan ("PIP")) that are outstanding on the date of the Spin-Off, will be
converted into new Zimmer stock options. The number of shares and the exercise
price of your new Zimmer options will be determined by the Bristol-Myers Squibb
Board of Directors based upon a conversion ratio that will be used for all
Zimmer employees and that preserves any gains earned through the date of
conversion. Your new Zimmer options will be vested in the same proportion that
your Bristol-Myers Squibb options were vested and the nonvested portion of your
new Zimmer options will vest from the original grant date of your Bristol-Myers
Squibb options according to the vesting schedule in such Bristol-Myers Squibb
options. Certain of your Bristol-Myers Squibb options were subject to a price
appreciation threshold of 30% for a period of eight years following grant. Your
new Zimmer options will also be subject to a 30% price appreciation threshold
that will be based upon the adjusted exercise price of your Zimmer options and
future share price appreciation of Zimmer shares subject to the requirement that
the price appreciation threshold be met for 15 consecutive trading days. Any
Bristol-Myers Squibb stock options granted to you after the date of this letter
agreement that are converted into new Zimmer stock options will reflect any
applicable conditions to exercisability such as vesting requirements or price
appreciation thresholds.

4. 2001 PERFORMANCE INCENTIVE PLAN. Your 2001 payment under the PIP will be
calculated in accordance with the following terms and conditions: (i) your full
target bonus will be in effect in 2001; (ii) your payment will be based upon
actual results versus targeted performance criteria through the Effective Date,
subject to the established PIP payout schedule; (iii) if the Effective Date is
on or before June 30, 2001, a six-month bonus payment will be made; (iv) if the
Effective Date occurs after June 30, 2001, you will accrue additional months of
bonus credit beyond six months subject to any applicable conditions of the PIP;
and (v) your 2001 PIP payment will be made on December 15, 2001 and February 15,
2002 consistent with the current plan provisions, provided that you remain
employed with Zimmer through the aforementioned payment dates.

5. SPECIAL SEVERANCE UPON TERMINATION OF EMPLOYMENT. In addition to the other
payments specified in this letter agreement, you may be eligible for special
severance payments pursuant to either (A) or (B) below (note that should you
become reemployed by Bristol-Myers Squibb or any of its affiliates following
your receipt of severance payments, you may be obligated to repay a portion of
any severance payments as required by the Bristol-Myers Squibb Company Severance
Plan ("BMS Severance Plan")). The special severance payments described in this
letter agreement will be in lieu of, and not in addition to, the severance (if
any) that might ordinarily have been payable to you under the terms of the BMS
Severance Plan.

      A.    EMPLOYMENT CONTINUED BY ZIMMER BUT TERMINATED WITHIN 12 MONTHS. In
            the event that your employment with Zimmer is initially continued
            after the Effective Date, but is subsequently terminated prior to
            the first anniversary of the date of the Spin-Off, and you do not at
            such time become reemployed by Bristol-Myers Squibb or any of its
            affiliates, you will receive severance "make-up" benefits (in lieu
            of any amount payable pursuant to the BMS Severance Plan). The
            severance benefits hereunder, when combined with any severance
            payments from Zimmer for which you may be eligible, will increase
            your total severance benefits under this paragraph to an amount
            equal to one year of your base salary at the rate in effect on the
            date immediately prior to the Effective Date (regardless of the
            amount that you would otherwise be entitled to receive under the
            terms of the BMS Severance Plan, unless such amount would be greater
            than one year of your base salary, in which case your total
            severance amount will be increased to such greater amount), plus, in
            the event that you are eligible for Rule of 70 benefits as of the
            Effective Date, the additional Rule of 70 supplemental severance
            payments that would be provided under the terms of the BMS Severance
            Plan (without offset against the amount payable under the first part
            of this sentence, and notwithstanding any limitation under Section
            VII of the BMS Severance Plan), and retiree medical benefits
            referenced under Section VII of the BMS Severance Plan, provided
            that you are not eligible to receive retiree medical benefits under
            any successor employer benefit plan. The severance make-up benefits
            described in this paragraph will be paid to you in accordance with
            the payment schedule and

<PAGE>

Paul D. Schoenle

Page 4

            subject to all of the terms and conditions of the BMS Severance Plan
            in effect as of the Effective Date (including but not limited to the
            terms providing for the eligibility for severance pay, and the
            determination of which circumstances constitute a termination
            pursuant to which severance pay would be payable).

      B.    EMPLOYMENT NOT CONTINUED BY ZIMMER. In the event that your
            employment is not continued by Zimmer as of the Effective Date, and
            you have neither been retained nor reemployed by Bristol-Myers
            Squibb at such time, you will be eligible to receive a severance
            benefit in an amount equal to one year of your base salary at the
            rate in effect on the date immediately prior to the Effective Date,
            (regardless of the amount that you would otherwise be entitled to
            receive under the terms of the BMS Severance Plan, unless such
            amount would be greater than one year of your base salary, in which
            case your total severance amount will be increased to such greater
            amount), plus, in the event that you are eligible for Rule of 70
            benefits as of the Effective Date, the additional Rule of 70
            supplemental severance payments that would be provided under the
            terms of the BMS Severance Plan (without offset against the amount
            payable under the first part of this sentence, and notwithstanding
            any limitation under Section VII of the BMS Severance Plan), and
            retiree medical benefits referenced under Section VII of the BMS
            Severance Plan. The severance benefits described herein will be paid
            to you in accordance with the payment schedule and subject to all of
            the terms and conditions of the BMS Severance Plan in effect as of
            the Effective Date, (including but not limited to the terms
            providing for the eligibility for severance pay, and the
            determination of which circumstances constitute a termination
            pursuant to which severance pay would be payable). You acknowledge
            and agree that, in the event that Zimmer provides severance payments
            to you, whether through contractual obligation or otherwise, the
            amount of severance payments that you actually receive from Zimmer
            will set off and reduce Bristol-Myers Squibb's obligations under
            this subparagraph (B) on a dollar-for-dollar basis.

6. VESTING IN PENSION PLAN AND SAVINGS PLAN. In addition to the incentives
specified in this letter agreement, your unvested benefits under the
Bristol-Myers Squibb Company Retirement Income Plan and the Bristol-Myers Squibb
Company Savings and Investment Program will become fully vested as of the
consummation of the Spin-Off.

7. SPECIAL PAYMENT EQUAL TO THE RULE OF 70 AMOUNT. In the event that (a) you are
not eligible to receive, and, in fact do not receive, the severance benefits
provided under the "Special Severance Upon Termination of Employment" provision
of this letter agreement, and either (b) Zimmer does not offer you participation
in an employer-sponsored defined benefit pension plan, or (c) you are offered
such participation but you do not ultimately become fully vested in such defined
benefit pension plan (for whatever reason), you will receive an amount equal to
the additional

<PAGE>

Paul D. Schoenle

Page 5

Rule of 70 payment that you would have received under the terms of the BMS
Severance Plan, calculated in the manner set forth in the second paragraph of
Section VII of the BMS Severance Plan (without regard to the limitation set
forth therein). You should notify Bristol-Myers Squibb promptly after the
occurrence of any event upon which you believe payment is required under this
paragraph.

8. CONDITIONS OF THIS LETTER AGREEMENT. The incentive payments and benefits
described in this letter agreement are contingent upon: (a) the Effective Date
occurring on or before September 30, 2001 and, with respect to payments and
benefits contingent upon a Spin-Off, the consummation of the Spin-Off on or
before March 31, 2002; (b) your continuous employment with Zimmer through and
including the date of the relevant award, and your cessation of employment
within the Bristol-Myers Squibb controlled group (as defined under section
1563(a) of the Internal Revenue Code) as a result of the Spin-Off; (c) your
execution on the date of the consummation of the Spin-Off, and the
effectiveness, of a general release in favor of Bristol-Myers Squibb, its
affiliates, and others related to such entities (including but not limited to
their directors, officers, employees) and a limited release of Zimmer, its
affiliates, and others related to such entities (including but not limited to
their directors, officers, employees) with respect to Zimmer's obligations in
connection with the Spin-Off, in form and substance satisfactory to
Bristol-Myers Squibb and Zimmer, (d) your honoring the need for strict
confidentiality regarding the IPO and the Spin-Off and the terms of this letter
agreement, neither of which should be discussed with anyone (other than your
personal financial or legal advisors) without the express and specific
permission of George P. Kooluris, Senior Vice President, Corporate Development,
it being acknowledged that matters relating to the IPO and the Spin-Off (except
the terms of this letter agreement) may be discussed only with employees of
Bristol-Myers Squibb and its affiliates and their legal and financial advisors
who are participating in the IPO and the Spin-Off process and no others (and
then only with those individuals on a "need to know" basis); (e) your providing
full support and cooperation in the best interests of Bristol-Myers Squibb and
Zimmer up to and including the date of the Spin-Off; and (f) following the
Spin-Off, your taking no action, excluding normal competitive activity not
contrary to law and not inconsistent with your other contractual obligations to
Bristol-Myers Squibb, Zimmer or their affiliates, but including any actions
prohibited by this letter agreement, which would be considered contrary to the
best interests of Bristol-Myers Squibb, Zimmer or their affiliates.

9. NON-COMPETE AND NON-SOLICITATION. As a condition to your receipt of any
payments or benefits under this letter agreement, you agree that, for a period
commencing on the date of your execution of this letter agreement and ending on
the date which is one year after the consummation of the Spin-Off you will not,
directly or indirectly, (i) own, manage, control or participate in the
ownership, management or control of, be employed or engaged by or otherwise
affiliated or associated as a consultant, independent contractor or otherwise
with, any other corporation, partnership, proprietorship, firm, association, or
other business entity, or otherwise engage in any business, which is engaged in
any manner in, or otherwise competes with, the

business of Zimmer or any of its affiliates in the United States of America or
any of the countries in which Zimmer or any of its affiliates is doing business,
(ii) solicit on behalf of any other corporation, partnership, proprietorship,
firm, association, or other business entity, any person or business that is a
customer or supplier of Zimmer or any of its affiliates, or (iii) solicit for
employment, hire, employ, or retain in any capacity (including but not limited
to as an employee, director, independent contractor, consultant or otherwise),
other than for employment within Zimmer or its affiliates in conjunction with
the IPO and Spin-Off or within Bristol-Myers Squibb or its affiliates, any
person who is employed or otherwise engaged on a full or part-time basis by
Bristol-Myers Squibb or its affiliates (including but not limited to Zimmer).
You understand and agree that a breach by you of this paragraph would be a
material breach of your obligations under this letter agreement, and that, if
any amounts have been provided to you under the terms of this letter agreement
prior to any such breach, in addition to any other remedy that may be available
to Bristol-Myers Squibb in law or at equity, upon demand, you will promptly
return all such amounts to Bristol-Myers Squibb or Zimmer as appropriate.

10. NOT AN EMPLOYMENT AGREEMENT. The terms of this letter agreement neither bind

or any successor thereto, nor confer any rights upon you with respect to the
continuation of employment by Bristol-Myers Squibb, Zimmer, their affiliates or
any successor thereto.

11. WITHHOLDING. It is understood and agreed that all amounts, payments or
benefits payable to you as described in this letter agreement represent gross

Zimmer or its affiliates or agents are hereby authorized to withhold any and all
applicable withholdings and taxes from any such amounts, payments or benefits.

12. EXCLUSIVE RETENTION AND SEVERANCE BENEFIT. In the event that any or all
other employees of Zimmer receive or are offered either a retention or similar
bonus payable upon or in connection with the IPO or the Spin-Off (a "Retention
Bonus"), or an enhanced severance benefit payable upon or in connection with the
IPO or the Spin-Off, you understand and agree that you will not be eligible to
receive such Retention Bonus or enhanced severance benefit, except as explicitly
set forth in this letter agreement.

13. RETURN OF COMPANY PROPERTY AND USE OF COMPANY PERQUISITES. In the event of
your separation from Bristol-Myers Squibb, Zimmer or their affiliates (whether
prior to or in connection with the IPO or Spin-Off), you agree to return all
property belonging to Bristol-Myers Squibb, Zimmer or their affiliates
(including but not limited to any company laptop or computers, and other
equipment, documents and property belonging to Bristol-Myers Squibb, Zimmer or
their affiliates) upon such separation (in accordance with the normal practice
relating thereto); provided, however, at Zimmer's discretion, you may continue
to retain use of your employer-provided automobile.

John S. Loveman-Krelle
[Address]

                            PERSONAL AND CONFIDENTIAL

Dear John:

                  Last October you and Bristol-Myers Squibb Company
("Bristol-Myers Squibb") executed a letter agreement dated October 19, 2000 (the
"2000 Agreement") that described the bonus payments and other incentives that
you would receive in the event that Zimmer, Inc. ("Zimmer") was sold to a
third-party entity on or before September 30, 2001. It now appears possible that
Bristol-Myers Squibb may divest its interest in Zimmer through a "spin-off"
transaction involving the distribution of Zimmer stock to Bristol-Myers Squibb
shareholders (the "Spin-Off"). The Spin-Off may be preceded by a public offering
of Zimmer shares (the "IPO"). During the divestiture process, we believe that
operating the Zimmer business as usual is in the best interests of Bristol-Myers
Squibb, Zimmer and its employees. To provide assurance to you and to help ensure
that the Zimmer business is managed and operated efficiently and effectively
both before and after the divestiture, Bristol-Myers Squibb and Zimmer wish to
offer you the incentives described in this letter. If these incentives are
satisfactory and you wish to participate, please sign and return this letter in
the manner described on the last page of this letter.

                  The terms and conditions of this letter agreement will apply
in the event of an IPO or Spin-Off of Zimmer that occurs on or before September
30, 2001 and, with respect to payments and benefits contingent upon a Spin-Off,
the consummation of the Spin-Off on or before March 31, 2002. In the event of a
disposition of Zimmer which is not an IPO or Spin-Off occurring on or before
September 30, 2001 and, with respect to payments and benefits contingent upon a
Spin-Off, if the Spin-Off is not completed on or before March 31, 2002, the
terms and conditions of this letter agreement will terminate and will not apply.
Please note that if Zimmer is sold to a third party entity on or before
September 30, 2001, you will receive the bonus payments and other incentives
subject to the conditions described in the 2000 Agreement.

                  As a member of the Zimmer management team, you are expected to
carry out the duties and responsibilities of your job during the coming months.
In addition, your assistance

will be necessary to complete the divestiture process. For your extra efforts
and cooperation in helping Bristol-Myers Squibb and Zimmer during this period,
you will be provided with the following incentives, subject to all of the terms
and conditions of this letter agreement:

1. SPECIAL STOCK OPTION AWARD. Effective on the date of the Spin-Off or, if it
occurs first, the IPO (the "Effective Date"), you will receive an option to
purchase shares of Zimmer stock with an economic value at the time of grant of
$175,000 using a generally accepted valuation methodology. This option will be
issued under a new option and equity compensation plan (the "Zimmer Stock
Incentive Plan") that will be adopted by Zimmer's Board of Directors. Your
option will vest in equal installments over a period of four years provided that
you remain employed with Zimmer during that time, or as provided otherwise under
the Zimmer Stock Incentive Plan. The exercise price will equal the fair market
value of Zimmer stock at the time the option is granted.

2. SPECIAL RESTRICTED STOCK AWARD. As of the Effective Date, you will receive a
grant of Zimmer restricted stock with a value (determined as if no restrictions
applied) of $60,000. The restricted stock will vest in three equal installments
on the third, fourth and fifth anniversaries of the grant of the award provided
that you remain employed with Zimmer during that time. Any dividends that are
payable on Zimmer stock will be paid to you on this restricted stock on a
current basis. This restricted stock will also be issued under the Zimmer Stock
Incentive Plan.

3. CONVERSION OF OUTSTANDING STOCK OPTIONS. Any Bristol-Myers Squibb stock
options granted to you prior to the Effective Date (including, but not limited
to, the options awarded to you on January 3, 2000 pursuant to a 50% reduction in
target cash bonus under the Bristol-Myers Squibb Company Performance Incentive
Plan ("PIP")) that are outstanding on the date of the Spin-Off, will be
converted into new Zimmer stock options. The number of shares and the exercise
price of your new Zimmer options will be determined by the Bristol-Myers Squibb
Board of Directors based upon a conversion ratio that will be used for all
Zimmer employees and that preserves any gains earned through the date of
conversion. Your new Zimmer options will be vested in the same proportion that
your Bristol-Myers Squibb options were vested and the nonvested portion of your
new Zimmer options will vest from the original grant date of your Bristol-Myers
Squibb options according to the vesting schedule in such Bristol-Myers Squibb
options. Certain of your Bristol-Myers Squibb options were subject to a price
appreciation threshold of 30% for a period of eight years following grant. Your
new Zimmer options will also be subject to a 30% price appreciation threshold
that will be based upon the adjusted exercise price of your Zimmer options and
future share price appreciation of Zimmer shares subject to the requirement that
the price appreciation threshold be met for 15 consecutive trading days.] Any
Bristol-Myers Squibb stock options granted to you after the date of this letter
agreement that are converted into new Zimmer stock options will reflect any
applicable conditions to exercisability such as vesting requirements or price
appreciation thresholds.

4. 2001 PERFORMANCE INCENTIVE PLAN. Your 2001 payment under the PIP will be
calculated in accordance with the following terms and conditions: (i) your full
target bonus will be in effect in 2001; (ii) your payment will be based upon
actual results versus targeted performance criteria through the Effective Date,
subject to the established PIP payout schedule; (iii) if the Effective Date is
on or before June 30, 2001, a six-month bonus payment will be made; (iv) if the
Effective Date occurs after June 30, 2001, you will accrue additional months of
bonus credit beyond six months subject to any applicable conditions of the PIP;
and (v) your 2001 PIP payment will be made on December 15, 2001 and February 15,
2002 consistent with the current plan provisions, provided that you remain
employed with Zimmer through the aforementioned payment dates.

5. SPECIAL SEVERANCE UPON TERMINATION OF EMPLOYMENT. In addition to the other
payments specified in this letter agreement, you may be eligible for special
severance payments pursuant to either (A) or (B) below (note that should you
become reemployed by Bristol-Myers Squibb or any of its affiliates following
your receipt of severance payments, you may be obligated to repay a portion of
any severance payments as required by the Bristol-Myers Squibb Company Severance
Plan ("BMS Severance Plan")). The special severance payments described in this
letter agreement will be in lieu of, and not in addition to, the severance (if
any) that might ordinarily have been payable to you under the terms of the BMS
Severance Plan.

      A.    EMPLOYMENT CONTINUED BY ZIMMER BUT TERMINATED WITHIN 12 MONTHS. In
            the event that your employment with Zimmer is initially continued
            after the Effective Date, but is subsequently terminated prior to
            the first anniversary of the date of the Spin-Off, and you do not at
            such time become reemployed by Bristol-Myers Squibb or any of its
            affiliates, you will receive severance "make-up" benefits (in lieu
            of any amount payable pursuant to the BMS Severance Plan). The
            severance benefits hereunder, when combined with any severance
            payments from Zimmer for which you may be eligible, will increase
            your total severance benefits under this paragraph to an amount
            equal to one year of your base salary at the rate in effect on the
            date immediately prior to the Effective Date (regardless of the
            amount that you would otherwise be entitled to receive under the
            terms of the BMS Severance Plan, unless such amount would be greater
            than one year of your base salary, in which case your total
            severance amount will be increased to such greater amount). The
            severance make-up benefits described in this paragraph will be paid
            to you in accordance with the payment schedule and subject to all of
            the terms and conditions of the BMS Severance Plan in effect as of
            the Effective Date, (including but not limited to the terms
            providing for the eligibility for severance pay, and the
            determination of which circumstances constitute a termination
            pursuant to which severance pay would be payable).

      B.    EMPLOYMENT NOT CONTINUED BY ZIMMER. In the event that your
            employment is not continued by Zimmer as of the Effective Date, and
            you have neither been

            retained nor reemployed by Bristol-Myers Squibb at such time, you
            will be eligible to receive a severance benefit in an amount equal
            to one year of your base salary at the rate in effect on the date
            immediately prior to the Effective Date, (regardless of the amount
            that you would otherwise be entitled to receive under the terms of
            the BMS Severance Plan, unless such amount would be greater than one
            year of your base salary, in which case your total severance amount
            will be increased to such greater amount). The severance benefits
            described herein will be paid to you in accordance with the payment
            schedule and subject to all of the terms and conditions of the BMS
            Severance Plan in effect as of the Effective Date, (including but
            not limited to the terms providing for the eligibility for severance
            pay, and the determination of which circumstances constitute a
            termination pursuant to which severance pay would be payable). You
            acknowledge and agree that, in the event that Zimmer provides
            severance payments to you, whether through contractual obligation or
            otherwise, the amount of severance payments that you actually
            receive from Zimmer will set off and reduce Bristol-Myers Squibb's
            obligations under this subparagraph (B) on a dollar-for-dollar
            basis.

6. VESTING IN PENSION PLAN AND SAVINGS PLAN. In addition to the incentives
specified in this letter agreement, your unvested benefits under the
Bristol-Myers Squibb Company Retirement Income Plan and the Bristol-Myers Squibb
Company Savings and Investment Program will become fully vested as of the
consummation of the Spin-Off.

7. CONDITIONS OF THIS LETTER AGREEMENT. The incentive payments and benefits
described in this letter agreement are contingent upon: (a) the Effective Date
occurring on or before September 30, 2001 and, with respect to payments and
benefits contingent upon a Spin-Off, the consummation of the Spin-Off on or
before March 31, 2002; (b) your continuous employment with Zimmer through and
including the date of the relevant award, and your cessation of employment
within the Bristol-Myers Squibb controlled group (as defined under section
1563(a) of the Internal Revenue Code) as a result of the Spin-Off; (c) your
execution on the date of the consummation of the Spin-Off, and the
effectiveness, of a general release in favor of Bristol-Myers Squibb, its
affiliates, and others related to such entities (including but not limited to
their directors, officers, employees) and a limited release of Zimmer, its
affiliates, and others related to such entities (including but not limited to
their directors, officers, employees) with respect to Zimmer's obligations in
connection with the Spin-Off, in form and substance satisfactory to
Bristol-Myers Squibb and Zimmer, (d) your honoring the need for strict
confidentiality regarding the IPO and the Spin-Off and the terms of this letter
agreement, neither of which should be discussed with anyone (other than your
personal financial or legal advisors) without the express and specific
permission of George P. Kooluris, Senior Vice President, Corporate Development,
it being acknowledged that matters relating to the IPO and the Spin-Off (except
the terms of this letter agreement) may be discussed only with employees of
Bristol-Myers Squibb and its

affiliates and their legal and financial advisors who are participating in the
IPO and the Spin-Off process and no others (and then only with those individuals
on a "need to know" basis); (e) your providing full support and cooperation in
the best interests of Bristol-Myers Squibb and Zimmer up to and including the
date of the Spin-Off; and (f) following the Spin-Off, your taking no action,
excluding normal competitive activity not contrary to law and not inconsistent
with your other contractual obligations to Bristol-Myers Squibb, Zimmer or their
affiliates, but including any actions prohibited by this letter agreement, which
would be considered contrary to the best interests of Bristol-Myers Squibb,
Zimmer or their affiliates.

8. NON-COMPETE AND NON-SOLICITATION. As a condition to your receipt of any
payments or benefits under this letter agreement, you agree that, for a period
commencing on the date of your execution of this letter agreement and ending on
the date which is one year after the consummation of the Spin-Off you will not,
directly or indirectly, (i) own, manage, control or participate in the
ownership, management or control of, be employed or engaged by or otherwise
affiliated or associated as a consultant, independent contractor or otherwise
with, any other corporation, partnership, proprietorship, firm, association, or
other business entity, or otherwise engage in any business, which is engaged in
any manner in, or otherwise competes with, the business of Zimmer or any of its
affiliates in the United States of America or any of the countries in which
Zimmer or any of its affiliates is doing business, (ii) solicit on behalf of any
other corporation, partnership, proprietorship, firm, association, or other
business entity, any person or business that is a customer or supplier of Zimmer
or any of its affiliates, or (iii) solicit for employment, hire, employ, or
retain in any capacity (including but not limited to as an employee, director,
independent contractor, consultant or otherwise), other than for employment
within Zimmer or its affiliates in conjunction with the IPO and Spin-Off or
within Bristol-Myers Squibb or its affiliates, any person who is employed or
otherwise engaged on a full or part-time basis by Bristol-Myers Squibb or its
affiliates (including but not limited to Zimmer). You understand and agree that
a breach by you of this paragraph would be a material breach of your obligations
under this letter agreement, and that, if any amounts have been provided to you
under the terms of this letter agreement prior to any such breach, in addition
to any other remedy that may be available to Bristol-Myers Squibb in law or at
equity, upon demand, you will promptly return all such amounts to Bristol-Myers
Squibb or Zimmer as appropriate.

9. NOT AN EMPLOYMENT AGREEMENT. The terms of this letter agreement neither bind
you to continued employment with Bristol-Myers Squibb, Zimmer, their affiliates
or any successor thereto, nor confer any rights upon you with respect to the
continuation of employment by Bristol-Myers Squibb, Zimmer, their affiliates or
any successor thereto.

10. WITHHOLDING. It is understood and agreed that all amounts, payments or
benefits payable to you as described in this letter agreement represent gross
amounts (as opposed to net after-tax amounts), and that Bristol-Myers Squibb,
Zimmer or its affiliates or agents are hereby authorized

<PAGE>

John S. Loveman-Krelle

to withhold any and all applicable withholdings and taxes from any such amounts,
payments or benefits.

11. EXCLUSIVE RETENTION AND SEVERANCE BENEFIT. In the event that any or all
other employees of Zimmer receive or are offered either a retention or similar
bonus payable upon or in connection with the IPO or the Spin-Off (a "Retention
Bonus"), or an enhanced severance benefit payable upon or in connection with the
IPO or the Spin-Off, you understand and agree that you will not be eligible to
receive such Retention Bonus or enhanced severance benefit, except as explicitly
set forth in this letter agreement.

12. RETURN OF COMPANY PROPERTY AND USE OF COMPANY PERQUISITES. In the event of
your separation from Bristol-Myers Squibb, Zimmer or their affiliates (whether
prior to or in connection with the IPO or Spin-Off), you agree to return all
property belonging to Bristol-Myers Squibb, Zimmer or their affiliates
(including but not limited to any company laptop or computers, and other
equipment, documents and property belonging to Bristol-Myers Squibb, Zimmer or
their affiliates) upon such separation (in accordance with the normal practice
relating thereto); provided, however, at Zimmer's discretion, you may continue
to retain use of your employer-provided automobile.

13. GOVERNING LAW; JURISDICTION. This letter agreement will be governed by and
construed under the laws of the State of New York, without regard to its
principles of conflict of laws. You and Bristol-Myers Squibb agree to submit to
the jurisdiction of the courts of the state of New York in the event of any
dispute regarding this letter agreement.

Please acknowledge your understanding of and agreement to the provisions of this
letter agreement by signing and returning a copy of this letter to me by March
9, 2001.

Very truly yours,

George P. Kooluris
Senior Vice President
Corporate Development
