Mr. Donald Kraft
[address]
[city, state, zipcode]


         Re:      Employment Letter Agreement (the "Agreement")
                  ---------------------------------------------

Dear Don:

It is my pleasure to formally confirm your promotion to the office of Corporate
Senior Vice President - Human Resources of Covance Inc. ("Covance") on the terms
and conditions of this Agreement.

Position
--------

As Corporate Senior Vice President - Human Resources, your duties include the
management of Covance's human resources function. In addition, you will perform
such other duties and responsibilities that I, as the Chief Executive Officer
("CEO") may assign to you from time to time. You will report to the CEO. Your
office will be located in Covance's World Headquarters, which, as you know, is
currently located at 210 Carnegie Center, Princeton, New Jersey, or such other
location as determined by the CEO.

Salary and Bonus
----------------

Your new salary will be $220,000 per year.

You will participate in the Covance Variable Compensation Plan (the "Bonus
Plan") subject to the terms and conditions thereof. Payouts under the Bonus Plan
are contingent upon a number of factors, as specified in the Bonus Plan,
including Covance and your performance. If budgeted targets and individual
performance criteria are met, you would be eligible for a bonus equal to 60% of
your earned base salary. The Bonus Plan allows for increased or decreased bonus
payments depending on performance, as determined in accordance thereunder, and
bonus payouts will occur approximately mid-March following the end of the
calendar Bonus Plan year. For 2002, your actual bonus percentage will be the
weighted average of your old target percentage and the new one, and your bonus
for 2002 will be determined in accordance with the Variable Compensation Plan
(i.e. such weighted average bonus percentage will be applied to your actual base
salary earned for 2002).

This Agreement does not constitute an amendment, modification or supplement to
the Bonus Plan and to the extent there are any inconsistencies between this
Agreement and the Bonus Plan, the latter shall govern. Further, the Bonus Plan
is subject to modification or discontinuation at the discretion of Covance. Your
base annual incentive target, however, may be increased from 60%, but not
decreased, while you are employed by Covance.

Pension Plan
------------

A supplemental executive retirement plan (as amended, modified or adopted from
time to time, the "SERP") has been adopted for the senior executives of Covance
in which you will participate. The SERP is a non-qualified, unfunded retirement
plan designed to provide retirement benefits to you starting at age 60 with
provisions enabling you to begin receiving reduced benefits if you retire at age
55. A copy of the plan will be available upon request.

                                                                          Page 2



Investment and Benefit Plans
----------------------------

You will be eligible to participate in all the Covance employee benefit plans,
including medical, dental, life insurance, disability, 401(k) savings plan, and
Employee Stock Purchase Plan ("ESPP"), in accordance with the terms and
conditions of those plans. In addition, you will receive four weeks vacation per
year. A copy of the current benefits program will be provided to you.

Auto and Financial Counseling Allowance
---------------------------------------

You will receive a non-accountable, gross monthly auto allowance of $1,070 per
month paid semi-monthly. This allowance is in lieu of any direct or per mile
charges you may incur while using your personal car on company business, except
for tolls and parking costs. You will be responsible for insurance and all other
expenses related to your car. In addition, you will also be eligible to
participate in other perquisites and/or benefits programs as are offered to all
other senior executives of Covance as a class. These include a tax/financial
counseling allowance of $6,000 per year under the terms of the Covance plan. Any
expenses actually incurred under this tax/financial counseling plan will be
grossed up for tax purposes at an incremental income tax rate of 45%.

Equity Awards
-------------

You may be awarded from time to time additional compensation (such as stock
options or performance shares) pursuant to Covance's 2002 Employee Equity
Participation Plan (as amended, modified or supplemented from time to time, the
"EEPP") or any additional or replacement incentive compensation or long-term
compensation program established by Covance for its senior officers. Any awards
under such programs shall be at such levels or in such amounts as Covance's
Board of Directors or the Compensation and Organization Committee thereof (the
"Compensation Committee") deems, in its sole discretion, appropriate for your
position and the performance of your duties.

Covance shall recommend to the Board of Directors a promotion related grant to
you of 5,000 stock options under the EEPP in 2002, all as more fully set forth
in the applicable Stock Option Agreement. The rights, obligations and other
conditions of any performance shares and stock options shall be as specified in
the EEPP and, as applicable, Restricted Stock Agreements and Stock Option
Agreements, as such agreements may be amended, modified or supplemented from
time to time, in each case between you and Covance.

Severance
---------

Except as provided below under the paragraph headed "Change-of-Control", should
you be involuntarily terminated for reasons other than for Cause, the Company
shall pay you the following:

         (i)      an amount equal to the sum of (a) one year of base salary
(payable on the normal payroll cycle) determined at the time of termination and
(b) one year of the annual incentive bonus (payable on the normal bonus cycle)
in an amount equal for such year to the product of your base salary in effect at
termination and 60% (the sum of (a) and (b) being, collectively, the
"Termination Payments");

         (ii)     during the period between the first anniversary of the date of
the involuntary termination of your employment with the Company for reasons
other than Cause and the second anniversary of such event, your base salary
(payable on the normal payroll cycle) with the Company determined at the time of
such involuntary termination in the event that, after reasonable efforts by you,
you have been unable to obtain a suitable alternative vocation, as determined by
the Company's Chief Executive Officer in his sole discretion;
<PAGE>

                                                                   June 25, 2002
                                                                          Page 3



         (iii)    your financial counseling and automobile allowance for the one
year period starting on the date of your involuntary termination from the
Company for reasons other than Cause and the first anniversary of the date of
such event on the terms and conditions of the Section of the Letter Agreement
entitled "Auto and Financial Counseling Allowance"; and

         (iv)     you shall be entitled to make the COBRA election for continued
medical and dental health insurance benefits for you and your eligible
dependents, subject to the terms and conditions of the applicable policies and
all COBRA requirements, for up to 18 months after the date of your termination
of employment. In the event you elect COBRA continuation, and such termination
was involuntary for reasons other than Cause, the Company shall pay you an
amount equal to the monthly premium for such coverage, less usual withholding
taxes and other customary withholdings, from the date of such involuntary
termination for reasons other than Cause until the date that is the later of (x)
the first anniversary of such involuntary termination and (y) the date you have
obtained a suitable alternative vocation, as determined in accordance with
Section (ii) above (such period, not to exceed 18 months after the date of your
involuntary termination from the Company for reasons other than Cause, being the
"Health Continuation Period"). For the remainder of such 18 month period, if
applicable, you shall be responsible for such costs. If you have not found a
suitable alternative vocation, as determined in accordance with Section (ii)
above on or prior to the date that is 18 months after your involuntary
termination from the Company for reasons other than Cause, then the Company
shall continue paying to you the foregoing premium payments until the earlier of
(I) the date you find a suitable alternative vocation, as determined in
accordance with Section (ii) above and (II) the date that is the second
anniversary of your involuntary termination from the Company for reasons other
than Cause. Such payments will be made to you in equal installments on the dates
during the Health Continuation Period, or such later period, as applicable, that
Covance makes its regular payroll payments. In the event you were terminated for
Cause and the COBRA election is still available to you under applicable law, and
you so elect the COBRA continuation, you shall be responsible for all health
benefit premium costs. Life insurance coverage will continue, at the Company's
expense, for the period during which the Company pays the premiums for health
coverage provided above.

Notwithstanding anything in this Severance section to the contrary, you agree
that if you obtain or are provided with medical, dental and life insurance from
a new employment position which provides comparable coverage and benefits to
that provided by the Company under the respective Company benefit plans and at
an equivalent or lesser expense (both deductible and direct) to you, then you
shall promptly notify the Company which of such insurance benefits is then being
provided to you and the Company shall cease providing such coverage or
discontinue paying the premiums for such insurance, as applicable.

Please refer to that certain Confidentiality and Non-Competition Agreement
between you and the Company (the "Non-Competition Agreement"). You agree that
any of the severance payments under Section (i) or (ii) above shall constitute
the payment of your base salary under Section 4(a)(ii) of the Non-Competition
Agreement.

"Cause" shall mean (i) your convictions of a felony or a misdemeanor if such
misdemeanor involves moral turpitude; (ii) your committing any act of gross
negligence or intentional misconduct in the performance or non-performance of
your duties as an employee of Covance or its affiliates, including, any actions
which constitute sexual harassment under applicable laws, rules or regulations;
(iii) your failure to perform your duties assigned for a period of thirty (30)
or more days unless such failure is caused by an Extended Disability; or (iv)
misappropriation of assets, personal dishonesty or intentional misrepresentation
of facts which may cause Covance or its affiliates financial or reputational
harm.

Should your employment be terminated by Covance because of an Extended
Disability (as defined below), and not for any other reason that constitutes
Cause, for 120 consecutive days where you have not returned to your duties on a
full-time basis after the expiration of such 120 day period within 30 days after
written notice of termination is given to you, Covance shall pay to you an
amount equal to the sum of (a) two years base salary (payable on the normal
payroll cycle)
<PAGE>

                                                                   June 25, 2002
                                                                          Page 4



determined at the time of termination, and (b) two years of the annual incentive
bonus (payable on the normal bonus cycles) in an amount equal for each such year
to the product of your base salary in effect at termination and 60% (the sum of
(a) and (b) being, collectively, the "Extended Disability Payments").

Extended Disability shall (i) mean you are unable, as a result of a medically
determinable physical or mental impairment, to perform the duties and services
of your position, or (ii) have the meaning specified in any disability insurance
policy maintained by Covance, whichever is more favorable to you.

Except as may be otherwise provided in applicable Covance compensation and
benefit plans, Covance shall not be liable for any salary or benefit payments to
you beyond the date of your voluntary termination of employment with Covance. In
the event of a termination of employment for Cause or Extended Disability, you
shall not be entitled to any compensation or other benefits not already earned
and owing to you on account of your services on the date of such termination of
employment except as provided above with respect to a termination for Extended
Disability. The provision of any benefits pursuant to this Agreement shall be in
lieu of, and not in addition to, any payment or benefits you otherwise would
have been entitled to pursuant to any severance pay plan of the Company,

base annual salary in effect at the time of the Event of Termination and (2) the
product of (a) 3 and (b) number that is 60% of your base annual salary in effect
at the time of the Event of Termination. Such payment will be made within 60
days of the Event of Termination. In addition to, and as a result of, the

For the purposes of this Agreement, an Event of Termination is defined to be a

within 24 months following a Change-of-Control (as defined below), or your
voluntary termination of your employment for any reason or no reason during the
one-month period commencing twelve months following a Change-of-Control and
ending thirteen months after such Change-of-Control (a "Voluntary Termination");
provided, however, that a Voluntary Termination shall not be an Event of
Termination if it arises from a Change-of-Control pursuant to clause (iv) under
the definition of Change-of-Control unless the tender offer or exchange offer is
a tender or exchange offer for securities representing 20% or more of the
combined voting power of Covance's then outstanding securities.

For purposes of this Agreement, a Change-of-Control is defined to occur when:

         (i)      any person (including as such term is used in Section 13(d)
and 14(d)(2) of the Securities Exchange Act of 1934) becomes the beneficial
owner, directly or indirectly, of Covance's securities representing 20% or more
of the combined voting power of Covance's then outstanding securities; or

         (ii)     as a result of a proxy contest or contests or other forms of
contested shareholder votes (in each case either individually or in the
aggregate), a majority of the individuals elected to serve on Covance's Board of
Directors are different than the individuals who served on Covance's Board of
Directors at any time within the two years prior to such proxy contest or
contests or other forms of contested shareholder votes (in each case either
individually or in the aggregate); or

                                                                   June 25, 2002
                                                                          Page 5



         (iii)    Covance shareholders approve a merger, or consolidation (where
in each case Covance is not the survivor thereof), or sale or disposition of all
or substantially all of Covance's assets or a plan or partial or complete
liquidation; or

         (iv)     an offeror (other than Covance) purchases shares of Covance
common stock pursuant to a tender or exchange offer for such shares.

For purposes of this Agreement, a Constructive Termination is defined to be:

         (i)      a material breach by Covance of this Agreement, including,
without limitation, a reduction in your then current salary or the percentage of
base salary eligible for incentive compensation;

         (ii)     a diminution of your responsibilities, status, title or duties
hereunder;

         (iii)    a relocation of your work place which increases the distance
between your principal residence and your work place by more than 25 miles;

         (iv)     a failure by Covance to provide you with benefits which are as
favorable to you in all material respects as those provided immediately prior to
the Change-of- Control; or

         (v)      the failure of any acquiror or successor in interest to the
business of Covance to agree in writing to be bound by the terms of this
Agreement within four months of any Change-of-Control.

In the event you are involved in any dispute about your rights under this
Agreement arising on or after a Change-of-Control, Covance shall pay all legal
costs and fees incurred by you in connection with such dispute promptly upon
receipt of any invoice relating thereto.

With respect to an Event of Termination, the benefits set forth under the
paragraph headed Auto and Financial Counseling Allowance and medical, dental,
disability and life insurance will be continued, to the extent they are not
otherwise prohibited under the respective plans, until you find other employment
but not longer than three years from the date of the Event of Termination.

Certain Additional Payments by Covance
--------------------------------------

         (a)      Anything in this Agreement to the contrary notwithstanding, in
the event it shall be determined that any payment or distribution by, to or for
the benefit of you, whether made under this Agreement or otherwise (a
"Payment"), would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended (the "Excise Tax"), then you shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by you of all taxes (including any Excise Tax) imposed
upon the Gross-Up Payment, you retain an amount of the Gross-Up Payment equal to
the Excise Tax imposed upon the Payments.

         (b)      All determinations required to be made under these provisions,
including whether a Gross-Up Payment is required and the amount of such Gross-Up
Payment, shall be made by the accounting firm utilized by Covance for the
preparation of its annual external financial statements (the "Accounting Firm")
which shall provide detailed supporting calculations both to Covance and you
within 30 days of the Event of Termination, if applicable, or such earlier time
as is requested by Covance. The Gross-Up Payment, if any, as determined pursuant
to this Paragraph (b), shall be paid to you within 10 days of the receipt of the
Accounting Firm's determination. Any determination by the Accounting Firm shall
be binding upon Covance and you. If subsequent final determinations of the
Excise Tax made by the Internal Revenue
<PAGE>

                                                                   June 25, 2002
                                                                          Page 6



Service give rise to additional Excise Tax, then additional Gross-Up Payments
shall be made by Covance to you within 10 days after the notice is received by
Covance of such final determination.

         (c)      You shall notify Covance in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by
Covance of a Gross-Up Payment. Such notification shall be given as soon as
practicable but no later than 10 business days after you know of such claim. You
shall not pay such claim prior to the expiration of the thirty-day period
following the date on which you give such notice to Covance (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due). If Covance notifies you in writing prior to the expiration of such
period that it desires to contest such claim, you shall:

                  (i)      give Covance any information reasonably requested by
         Covance relating too such claim,

                  (ii)     take such action in connection with contesting such
         claims as Covance shall reasonably request in writing from time to
         time, including, without limitation, accepting legal representation
         with respect to such claim by an attorney selected by Covance,

                  (iii)    cooperate with Covance in good faith in order
         effectively to contest such claim, and

                  (iv)     permit Covance to participate in any proceedings
         relating to such claim;

provided, however, that Covance shall bear all costs and expenses incurred in
connection with such contest and shall indemnify and hold you harmless, on an
after-tax basis, for any Excise Tax or income tax imposed as a result of such
contest or representation and payment of costs and expenses. Covance shall
control all proceedings taken in connection with such contest. Covance may, at
its sole option, either direct you to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and you agree to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as Covance shall
determine; provided, however, that if Covance directs you to pay such claim and
sue for a refund, Covance shall advance the amount of such payment to you on an
interest-free basis and shall indemnify and hold you harmless, on an after-tax
basis, from any Excise Tax or income tax imposed with respect to such advance.

         (d)      If, after the receipt by you of an amount advanced by Covance
pursuant to Paragraph (c), you become entitled to receive any refund with
respect to such claim, you shall promptly pay to Covance the amount of such
refund (together with any interest paid or credited thereon after taxes
applicable thereto). If, after the receipt by you of an amount advanced by
Covance pursuant to Paragraph (c), a final determination is made that you shall
not be entitled to any refund with respect to such claim, then such advance
shall be forgiven and shall not be required to be repaid and the amount of such
advance shall offset the amount of Gross-Up Payment required to be paid.

Injunctive Relief
-----------------

You agree that the remedies available to Covance at law for any breach of any of
your obligations under this Agreement may be inadequate, and you accordingly
agree and consent that temporary or permanent injunctive relief, and/or an order
of specific performance, may be granted in any proceeding which may be brought
to enforce any provision hereof, without the necessity of proof of actual
damage, in addition to any other remedies available to Covance at law.

Outplacement
------------

If there has been an Event of Termination, Covance shall provide for you, at
Covance's cost, executive outplacement support for one-year following such
termination.

continuation payments described in Section (ii) of the section entitled
Severance of this Letter Agreement or the payments specified under the paragraph
headed "Change of Control", as applicable) shall be subject to your execution
and delivery to Covance of a release in form and substance reasonably
satisfactory to Covance of all claims, demands, suits or actions, whether in law
or at equity, you have or may have relating to or giving rise from such Event of
Termination or non-Cause termination.

Agreement, and to the extent there is any inconsistency between the Agreement
and any other plan (benefit, compensation or otherwise, including without
limitation the EEPP, SERP, ESOP, 401(k) Savings Plan, and ESPP), of Covance,

nothing in this Agreement shall constitute a limitation on Covance's right to
modify or discontinue any such plans or policies.

reimbursement for business expenses, professional dues, etc. will be
administered in accordance with company policies, as they may be amended,
modified or supplemented from time to time.
