                               SEVERANCE AGREEMENT

                  THIS AGREEMENT, dated as of June 15, 2000 (the "Effective
Date"), is made by and between Hayes Lemmerz International, Inc., a Delaware
corporation (the "Company"), and [INSERT NAME] (the "Executive").

                  WHEREAS, the Company considers it essential to the best
interests of its stockholders to foster the continued employment of key
management personnel; and

                  WHEREAS, the Board recognizes that the possibility of a Change
in Control exists and that such possibility, and the uncertainty and questions
which it may raise among management, may result in the departure or distraction
of management personnel to the detriment of the Company and its stockholders;
and

                  WHEREAS, the Board has determined that appropriate steps
should be taken to reinforce and encourage the continued attention and
dedication of members of the Company's management, including the Executive, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a Change in Control;

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants herein contained, the Company and the Executive hereby agree as
follows:

                  1. Defined Terms. The definitions of certain capitalized terms
used in this Agreement are provided in the last Section hereof.

                  2. Term of Agreement. The Term of this Agreement shall
commence on the Effective Date hereof and shall continue in effect through the
third anniversary thereof; provided, however, that commencing on the first
anniversary of the Effective Date and each anniversary thereafter (each such
date a "Renewal Date"), the Term shall automatically be extended for one
additional year unless, on or prior to such Renewal Date, the Company or the
Executive shall have given notice not to extend the Term; and further provided,
however, that if a Change in Control shall have occurred during the Term, the
Term shall expire no earlier than twenty-four (24) months beyond the month in
which such Change in Control occurred.

                  3. Immediate Effect of Change in Control. Promptly following a
Change in Control, the Executive shall be entitled to the immediate payment of
all unpaid compensation amounts (including the pro rata bonus payment for the
current fiscal year under any bonus plan for which he is eligible ("Pro-rata
Bonus") and all unpaid bonuses with respect to any prior fiscal year) with
respect to the Executive's employment. For purposes of this Section 3, Pro-rata
Bonus shall be an amount equal to the product of (1) the product of (x) the

<PAGE>   2

Executive's base salary as in effect immediately prior to the Change in Control
and (y) the greater of (A) the Executive's normative bonus percentage for the
fiscal year in which the Change in Control occurs and (B) the Executive's
estimated bonus percentage calculated in good faith by the Company's Finance
Department determined by projecting performance through the end of the fiscal
year in which the Change in Control occurs and (2) a fraction, the numerator of
which is the number of days in the fiscal year in which the Change in Control
occurs through the date of the Change in Control, and the denominator of which
is 365. The Pro-rata Bonus paid shall be subtracted from the amount otherwise
due the Executive as a bonus for the fiscal year in which the Change in Control
occurs, but such Pro-rata Bonus becomes a vested benefit upon a Change in
Control and in no event shall the Executive have to repay all or any portion of
the Pro-rata Bonus.

                  4. Company's Covenants Summarized. In order to induce the
Executive to remain in the employ of the Company, the Company agrees, under the
conditions described herein, to pay the Executive the Severance Payments and the
other payments and benefits described herein. Except as provided in Section 9.1
hereof, no Severance Payments shall be payable under this Agreement unless there
shall have been (or, under the terms of the second sentence of Section 6.1
hereof, there shall be deemed to have been) a termination of the Executive's
employment with the Company on or following a Change in Control and during the
Term. This Agreement shall not be construed as creating an express or implied
contract of employment and, except as otherwise agreed in writing between the
Executive and the Company, the Executive shall not have any right to be retained
in the employ of the Company.

                  5.  Compensation Other Than Severance Payments.

                  5.1 Following a Change in Control and during the Term, during
any period that the Executive fails to perform the Executive's full-time duties
with the Company as a result of incapacity due to physical or mental illness,
the Company shall pay the Executive's full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits payable to the Executive under the terms of any compensation or
benefit plan, program or arrangement (other than the Company's short- or
long-term disability plan, as applicable, to the extent such benefits would be
duplicative and their nonpayment would not prejudice Executive's future
entitlement to benefits) maintained by the Company during such period, until the
Executive's employment is terminated by the Company for Disability.

                  5.2 If the Executive's employment shall be terminated for any
reason on or following a Change in Control and during the Term, the Company
shall pay the Executive's full salary to the Executive through the Date of
Termination at the rate in effect immediately prior to the Date of Termination
or, if higher, the rate in effect immediately prior to the first occurrence of
an event or circumstance constituting Good Reason, together with all
compensation and benefits payable to the Executive through the Date of
Termination under the terms of the Company's compensation and benefit plans,
programs or arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as

                                       2

<PAGE>   3

in effect immediately prior to the first occurrence of an event or circumstance
constituting Good Reason (including all unpaid bonuses with respect to any prior
fiscal year). In addition, if the Executive's employment is terminated on or
following a Change in Control and during the Term, other than (A) by the Company
for Cause, (B) by reason of death or Disability, or (C) by the Executive without
Good Reason, then the Company shall pay Executive an amount equal to the product
of (1) the product of (x) the Executive's base salary as in effect immediately
prior to the Date of Termination, or, if higher, as in effect immediately prior
to the first occurrence of an event or circumstance constituting Good Reason
(the greater of such amounts, the "Base Salary") and (y) the Executive's
normative bonus percentage for the year in which the Date of Termination occurs,
or if higher, the normative bonus percentage for the fiscal year in which the
Change in Control occurs or the normative bonus percentage in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason (the greatest of such percentages, the "Bonus Percentage") and (2) a
fraction, the numerator of which is the number of days in the fiscal year in
which the Date of Termination occurs through the date of the Date of
Termination, and the denominator of which is 365; it being understood that, if
the Date of Termination is in the same fiscal year as the Change in Control, the
Pro-rata Bonus calculated pursuant to Section 3 shall be subtracted from the
amount payable pursuant to this sentence of Section 5.2 but shall not reduce the
amount payable below zero.

                  5.3 If the Executive's employment shall be terminated for any
reason on or following a Change in Control and during the Term, the Company
shall pay to the Executive the Executive's normal post-termination compensation
and benefits as such payments become due. Such post-termination compensation and
benefits shall be determined under, and paid in accordance with, the Company's
retirement, insurance and other compensation or benefit plans, programs and
arrangements as in effect immediately prior to the Date of Termination or, if
more favorable to the Executive, as in effect immediately prior to the
occurrence of the first event or circumstance constituting Good Reason.

                  6.  Severance Payments.

                  6.1 If the Executive's employment is terminated on or
following a Change in Control and during the Term, other than (A) by the Company
for Cause, (B) by reason of death or Disability, or (C) by the Executive without
Good Reason, then the Company shall pay the Executive the amounts, and provide
the Executive the benefits, described in this Section 6.1 ("Severance Payments")
and Section 6.2, in addition to any payments and benefits to which the Executive
is entitled under Section 5 hereof or otherwise (except as provided herein). For
purposes of this Agreement, the Executive's employment shall be deemed to have
been terminated following a Change in Control by the Company without Cause or by
the Executive with Good Reason, if (i) the Executive's employment is terminated
by the Company without Cause prior to a Change in Control (whether or not a
Change in Control ever occurs) and such termination was at the request or
direction of a Person who enters into an agreement with the Company the
consummation of which would constitute a Change in Control, (ii) the Executive
terminates his employment for Good Reason prior to a Change in Control (whether
or not a Change in Control ever occurs) and the circumstance or event which

                                       3

<PAGE>   4

constitutes Good Reason occurs at the request or direction of such Person, or
(iii) the Executive's employment is terminated by the Company without Cause or
by the Executive for Good Reason and such termination or the circumstance or
event which constitutes Good Reason is otherwise in connection with or in
anticipation of a Change in Control (whether or not a Change in Control ever
occurs).

                  (A) In lieu of any further salary payments to the Executive
for periods subsequent to the Date of Termination and in lieu of any severance
benefit otherwise payable to the Executive (whether pursuant to any employment
agreement, plan, policy or otherwise), the Company shall pay to the Executive a
lump sum severance payment, in cash, equal to [three] [two] [one and one
half](1) times the sum of (i) the Base Salary and (ii) the product of (x) the
Base Salary and (y) the Bonus Percentage.

                  (B) For the twenty-four (24) month period immediately
following the Date of Termination, the Company shall arrange to provide the
Executive and his dependents life, disability, accident and health insurance
benefits substantially similar to those provided to the Executive and his
dependents immediately prior to the Date of Termination or, if more favorable to
the Executive, those provided to the Executive and his dependents immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason, at no greater cost to the Executive than the cost to the Executive
immediately prior to such date or occurrence; provided, however, that, unless
the Executive consents to a different method (after taking into account the
effect of such method on the calculation of "parachute payments" pursuant to
Section 6.2 hereof), such health insurance benefits shall be provided through a
third-party insurer. Benefits otherwise receivable by the Executive pursuant to
this Section 6.1 (B) shall be reduced to the extent benefits of the same type
are received by or made available to the Executive by another Employer of the
Executive during the twenty-four (24) month period following the Executive's
termination of employment (and any such benefits received by or made available
to the Executive shall be reported to the Company by the Executive); provided,
however, that the Company shall reimburse the Executive for the excess, if any,
of the cost of such benefits to the Executive over such cost immediately prior
to the Date of Termination or, if more favorable to the Executive, the first
occurrence of an event or circumstance constituting Good Reason.

                  (C) For purposes of COBRA health benefit continuation under
section 4980B of the Code, the cessation of benefits pursuant to Section 6.1(B)
shall be treated as though such cessation is the "qualifying event" under
section 4980B(f)(3) of the Code for purposes of determining the period of
coverage.

                  (D) The Company shall pay to the Executive a lump sum amount
equal to one hundred thousand dollars ($100,000).

--------
(1)      Three times for CEO, two times for his direct reports, one and one-half
         times for others.

                                       4

<PAGE>   5

                 (E) The Company shall, at its sole expense as incurred,
provide Executive with "key executive level" outplacement services at a cost of
no more than fifteen percent (15%) of the sum of (1) Base Salary and (2) the
Bonus Percentage multiplied by Base Salary.

                  6.2 (A) Whether or not the Executive becomes entitled to the
Severance Payments, if any of the payments or benefits received or to be
received by the Executive in connection with a Change in Control or the
Executive's termination of employment (whether pursuant to the terms of this
Agreement or any other plan, arrangement or agreement with the Company, any
Person whose actions result in a Change in Control or any Person affiliated with
the Company or such Person) (all such payments and benefits, excluding the
Gross-Up Payment, being hereinafter referred to as the "Total Payments") will be
subject to the Excise Tax, the Company shall pay to the Executive an additional
amount (the "Gross-Up Payment") such that the net amount retained by the
Executive, after deduction of any Excise Tax on the Total Payments and any
federal, state and local income and employment taxes and any penalties, interest
or fees incurred by the Executive as a result of any payment under Section 6.2
being made later than five business days prior to the due date of the excise tax
with respect to which it is paid and any Excise Tax upon the Gross-Up Payment,
shall be equal to the Total Payments.

                       (B) For purposes of determining whether any of the Total
Payments will be subject to the Excise Tax and the amount of such Excise Tax,
(i) all of the Total Payments shall be treated as "parachute payments" (within
the meaning of section 280G(b)(2) of the Code) unless, in the opinion of tax
counsel ("Tax Counsel") reasonably acceptable to the Executive and selected by
the accounting firm which was, immediately prior to the Change in Control, the
Company's independent auditor (the "Auditor"), such payments or benefits (in
whole or in part) do not constitute parachute payments, including by reason of
section 280G(b)(4)(A) of the Code, (ii) all "excess parachute payments" within
the meaning of section 280G(b)(l) of the Code shall be treated as subject to the
Excise Tax unless, in the opinion of Tax Counsel, such excess parachute payments
(in whole or in part) represent reasonable compensation for services actually
rendered (within the meaning of section 280G(b)(4)(B) of the Code) in excess of
the Base Amount allocable to such reasonable compensation, or are otherwise not
subject to the Excise Tax, and (iii) the value of any noncash benefits or any
deferred payment or benefit shall be determined by the Auditor in accordance
with the principles of sections 280G(d)(3) and (4) of the Code. For purposes of
determining the amount of the Gross-Up Payment, the Executive shall be deemed to
pay federal income tax at the highest marginal rate of federal income taxation
in the calendar year in which the Gross-Up Payment is to be made and state and
local income taxes at the highest marginal rate of taxation in the state and
locality of the Executive's residence or the Executive's place of business,
whichever is higher, on the Date of Termination (or if there is not yet a Date
of Termination, then the date on which the Gross-Up Payment is calculated for
purposes of this Section 6.2), net of the maximum reduction in federal income
taxes which could be obtained from deduction of such state and local taxes.

                       (C) In the event that the Excise Tax is finally
determined to be less than the amount taken into account hereunder in
calculating the Gross-Up Payment, the

                                       5

<PAGE>   6

Executive shall repay to the Company, within five (5) business days following
the time that the amount of such reduction in the Excise Tax is finally
determined, the portion of the Gross-Up Payment attributable to such reduction
(including that portion of the Gross-Up Payment attributable to the Excise Tax
and federal, state and local income and employment taxes imposed on the Gross-Up
Payment being repaid by the Executive), to the extent that such repayment
results in a reduction in the Excise Tax and a dollar-for-dollar reduction in
the Executive's taxable income and wages for purposes of federal, state and
local income and employment taxes, plus interest on the amount of such repayment
at 120% of the rate provided in section 1274(b)(2)(B) of the Code.
Notwithstanding the foregoing, in the event any portion of the amount to be
repaid to the Company has been paid to any tax authority, repayment thereof
shall not be required until actual refund or credit of such portion has been
made to Executive, and interest payable to the Company shall not exceed the
interest received or credited to Executive by such tax authority. In the event
that the Excise Tax is determined to exceed the amount taken into account
hereunder in calculating the Gross-Up Payment (including by reason of any
payment the existence or amount of which cannot be determined at the time of the
Gross-Up Payment), the Company shall make an additional Gross-Up Payment in
respect of such excess (including any interest, penalties or additions payable
by the Executive with respect to such excess and the Gross-Up Payment
attributable to the Excise Tax and federal, state, and local income and
employment taxes imposed on the Gross-Up Payment being made to the Executive)
within five (5) business days following the time that the amount of such excess
is finally determined. The Executive and the Company shall each reasonably
cooperate with the other in connection with any administrative or judicial
proceedings concerning the existence or amount of liability for Excise Tax with
respect to the Total Payments.

                  6.3 The payments provided in subsections (A), of Section 6.1
hereof and in Section 6.2 hereof shall be made not later than the fifth day
following the Date of Termination (or if there is no Date of Termination, then
the date on which the Gross-up Payment is calculated for purposes of Section 6.2
hereof); provided, however, that if the amounts of such payments cannot be
finally determined on or before such day, the Company shall pay to the Executive
on such day an estimate, as determined in good faith by the Company or, in the
case of payments under Section 6.2 hereof, in accordance with Section 6.2
hereof, of the minimum amount of such payments to which the Executive is clearly
entitled and shall pay the remainder of such payments (together with interest on
the unpaid remainder (or on all such payments to the extent the Company fails to
make such payments when due) at 120% of the rate provided in section
1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined but
in no event later than the thirtieth (30th) day after the Date of Termination.
In the event that the amount of the estimated payments exceeds the amount
subsequently determined to have been due, such excess shall constitute a loan by
the Company to the Executive, payable on the fifth (5th) business day after
demand by the Company (together with interest at 120% of the rate provided in
section 1274(b)(2)(B) of the Code).

                  6.4 The Company also shall pay to the Executive all legal fees
and expenses incurred by the Executive in disputing in good faith any issue
hereunder relating to the termination of the Executive's employment, in seeking
in good faith to obtain or enforce any

                                       6

<PAGE>   7

benefit or right provided by this Agreement or in connection with any tax audit
or proceeding to the extent attributable to the application of section 4999 of
the Code to any payment or benefit provided hereunder. Such payments shall be
made within five (5) business days after delivery of the Executive's written
requests for payment accompanied with such evidence of fees and expenses
incurred as the Company reasonably may require.

                  7.  Termination Procedures and Compensation During Dispute.

                  7.1 Notice of Termination. After a Change in Control and
during the Term, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with Section 11
hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

                  7.2 Date of Termination. "Date of Termination," with respect
to any purported termination of the Executive's employment after a Change in
Control and during the Term, shall mean (i) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such thirty (30) day period), and
(ii) if the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
the Company, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive, shall
not be less than fifteen (15) days nor more than sixty (60) days, respectively,
from the date such Notice of Termination is given).

                  7.3 Dispute Concerning Termination. If within fifteen (15)
days after any Notice of Termination is given, or, if later, prior to the Date
of Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date prior to the date on which the Term ends or
(ii) the date on which the dispute is finally resolved, either by mutual written
agreement of the parties or by a final judgment, order or decree of an
arbitrator or a court of competent jurisdiction (which is not appealable or with
respect to which the time for appeal therefrom has expired and no appeal has
been perfected); provided, however, that the Date of Termination shall be

                                       7

<PAGE>   8

extended by a notice of dispute only if such notice is given in good faith and
the party providing notice pursues the resolution of such dispute with
reasonable diligence.

                  7.4 Compensation During Dispute. If a purported termination
occurs on or following a Change in Control and during the Term and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in effect when the notice
giving rise to the dispute was given or, if higher, as in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason (including, but not limited to, Base Salary) and continue the Executive
as a participant in all compensation, benefit and insurance plans in which the
Executive was participating when the notice giving rise to the dispute was
given, until the Date of Termination, as determined in accordance with Section
7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other
amounts due under this Agreement (other than those due under the first sentence
of Section 5.2 hereof) and shall not be offset against or reduce any other
amounts due under this Agreement.

                  8. No Mitigation. The Company agrees that, if the Executive's
employment with the Company terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Company pursuant to this Agreement. Further, the
amount of any payment or benefit provided for in this Agreement (other than
Section 6.1(B) hereof) shall not be reduced by any compensation earned by the
Executive as the result of employment by another employer, by retirement
benefits, by offset against any amount claimed to be owed by the Executive to
the Company, or otherwise.

                  9.  Successors; Binding Agreement; Prior Agreement.

                  9.1 This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns. In addition to any
obligations imposed by law upon any successor to the Company, the Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or
assets of the Company to expressly assume and agree in writing to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place. The Company will
require any ultimate parent entity, as defined in [16 C.F.R. 8801,1(a)(3)], of
any Person who acquires 90% of the outstanding shares of common stock of the
Company or the outstanding voting securities of the Company entitled to vote
generally in the election of directors (including through a merger in which the
Company does not survive or as a result of which the Company becomes a
subsidiary of another Person or a consolidation involving the Company and
another Person) to assume and agree in writing to perform as a joint and several
obligor of the Company (including any successor to the Company), this Agreement
in the same manner and to the same extent as the Company. Failure of the Company
to obtain such assumption and agreement in writing from a successor or its
parent as described in the preceding sentences after notice and a reasonable
cure period (not to exceed ten days from the date such notice is received) shall
be a breach of this Agreement and shall entitle the Executive to compensation

                                       8

<PAGE>   9

from the Company in the same amount and on the same terms as the Executive would
be entitled to hereunder if the Executive were to terminate the Executive's
employment for Good Reason after a Change in Control, except that, for purposes
of implementing the foregoing, the date on which any such succession becomes
effective shall be deemed the Date of Termination.

                  9.2 This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

                  9.3 The Company and the Executive were parties to a Severance
Agreement dated as of [November 6, 1995] (the "Prior Agreement"), which is no
longer in effect. In consideration of the Company entering into this Agreement,
the Executive acknowledges that the Prior Agreement is no longer in effect and
hereby releases the Company and its directors, officers, stockholders and their
respective affiliates from any and all liabilities or obligations arising under
the Prior Agreement.

                  10. Insurance and Indemnification. From and after a Change in
Control, including after the termination of Executive's employment, the Company
shall indemnify, defend and hold the Executive harmless from and against any and
all expenses, liabilities, damages, costs, judgments, penalties, fines and
amounts paid in settlement, incurred in good faith by Executive in connection
with any proceeding involving Executive by reason of Executive's being or having
been an officer, director, employee or agent of the Company (or any affiliate of
the Company) to the fullest extent permitted by law, whether or not Executive
is, or is threatened to be made, a party to any threatened, pending, or
completed proceeding, and whether or not Executive is successful in such
proceeding. In addition, upon receipt from Executive of (i) a written request
for an advancement of reasonable expenses which Executive reasonably believes
will be subject to indemnification hereunder and (ii) a written undertaking by
Executive to repay any such amounts if it shall ultimately be determined that
the Executive is not entitled to indemnification under this Agreement or
otherwise, the Company shall advance such expenses to Executive or pay such
expenses for Executive, all in advance of the final disposition of any such
matter. From and after a Change in Control, including after the termination of
Executive's employment hereunder, Executive shall have coverage under a
director's and officer's liability insurance policy in amounts no less than, and
on terms no less favorable than those, provided to senior executive officers of
the Company from time to time.

                  11. Notices. For the purpose of this Agreement, notices and
all other communications provided for in the Agreement shall be in writing and
shall be deemed to have been duly given when delivered or mailed by United
States registered mail, return receipt requested, postage prepaid, addressed, if
to the Executive, to the address inserted below the Executive's signature on the
final page hereof and, if to the Company, to the address

                  12. Miscellaneous. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing and signed by the Executive and such officer as may be
specifically designated by the Board. No waiver by either party hereto at any
time of any breach by the other party hereto of, or of any lack of compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or at any prior or subsequent time. This Agreement supersedes any
other agreements or representations, oral or otherwise, express or implied, with
respect to the terms and conditions of the Executive's employment with the
Company only in the event that the Executive's employment with the Company is
terminated on or following a Change in Control, by (i) the Company other than
for Cause or (ii) the Executive other than for Good Reason. The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Delaware. All references to sections of the Exchange
Act or the Code shall be deemed also to refer to any successor provisions to
such sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law and any
additional withholding to which the Executive has agreed. The obligations of the
Company and the Executive under this Agreement which by their nature may require
either partial or total performance after the expiration of the Term (including,
without limitation, those under Sections 5, 6, 7 and 10 hereof) shall survive
such expiration.

                  13. Validity. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

                  14. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

                  15. Settlement of Disputes. All claims by the Executive for
benefits under this Agreement shall be directed to the Board and shall be in
writing. Any denial by the Board of a claim for benefits under this Agreement
shall be delivered to the Executive in writing and shall set forth the specific
reasons for the denial and the specific provisions of this Agreement relied
upon. The Board shall afford a reasonable opportunity to the Executive for a
review of the decision denying a claim and shall further allow the Executive to
appeal to the Board a

decision of the Board within sixty (60) days after notification by the Board
that the Executive's claim has been denied. The Executive shall be entitled to

of appropriate jurisdiction.

such failure resulting from the Executive's incapacity due to physical or mental

specifically identifies the manner in which the Board believes that the
Executive has not substantially performed the Executive's duties, or (ii) the
willful engaging by the Executive in conduct which is demonstrably and

failure to act, based upon authority given pursuant to a resolution duly adopted
by the Board or upon the instructions of the Chief Executive Officer or based
upon the advice of counsel for the Company shall be conclusively presumed to be
done, or omitted to be done, by the Executive in good faith and in the best

                  Control; or

                                    (VII) any purported termination of the
                  Executive's employment which is not effected pursuant to a
                  Notice of Termination satisfying the requirements of Section
                  7.1 hereof; for purposes of this Agreement, no such purported
                  termination shall be effective.

                  The Executive's right to terminate the Executive's employment
for Good Reason shall not be affected by the Executive's incapacity due to
physical or mental illness. The Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any act or failure
to act constituting Good Reason hereunder.

                  For purposes of any determination regarding the existence of
Good Reason, any claim by the Executive that Good Reason exists shall be
presumed to be correct unless the Company establishes to the Board by clear and
convincing evidence that Good Reason does not exist.

                  (P) "Gross-Up Payment" shall have the meaning set forth in
Section 6.2 hereof.

         It is the purpose of this Plan to provide a means whereby Eligible
Employees may purchase Common Stock through payroll deductions. It is intended
to provide a further incentive for Employees to promote the best interests of
the Company and to encourage stock ownership by Employees in order to
participate in the Company's economic progress.

         It is the intention of the Company to have the Plan qualify as an
"employee stock purchase plan" within the meaning of Section 423 of the Code and
the provisions of the Plan shall be construed in a manner consistent with the
Code.

                              III. ADMINISTRATION

         The Plan shall be administered by the Committee. The Committee shall
have authority to make rules and regulations for the administration of the Plan,

<PAGE>   3

decisions with regard thereto shall be final and conclusive. The Committee shall

Employees and Participants for purposes of administering the Plan, and shall
notify Eligible Employees promptly of its election of the term of each

                                   IV. SHARES

         There shall be 300,000 shares of Common Stock reserved for issuance to
and purchase by Participants under the Plan, subject to adjustment in accordance
with Section XXI hereof. The shares of Common Stock subject to the Plan shall be
either shares of authorized but unissued Common Stock or shares of Common Stock
reacquired by the Company. Shares of Common Stock covered by the unexercised
portion of any terminated purchase right may again be subject to purchase rights
granted under the Plan.

                               V. PURCHASE PRICE

         The purchase price per share of the shares of Common Stock sold to
Participants under this Plan for any Purchase Period shall be the lesser of (a)
85% of the Fair Market Value of a share of Common Stock on the first day of such
Purchase Period, or (b) 85% of the Fair Market Value of a share of Common Stock
on the Exercise Date of such Purchase Period.

                 VI. GRANT OF PURCHASE RIGHT TO PURCHASE SHARES

         Each Eligible Employee shall be granted a purchase right effective on
the first day of each Purchase Period to purchase a number of full shares of
Common Stock (subject to adjustment as provided in Section XXI). No Eligible
Employee shall be permitted to purchase shares under this Plan (or under any
other "employee stock purchase plan" within the meaning of Section 423(b) of the
Code, of the Company ) with an aggregate Fair Market Value (as determined as of
the first day of the Purchase Period) in excess of $25,000 for any one calendar
year within the meaning of Section 423(b)(8) of the Code. For a given Purchase
Period, payroll deductions shall commence on the first day of the Purchase
Period and shall end on the related Exercise Date, unless sooner altered or
terminated as provided in the Plan.

         Anything herein to the contrary notwithstanding, if, as of the first
day of a Purchase Period, any Eligible Employee entitled to purchase shares
hereunder would be deemed for the purposes of Section 423(b)(3) of the Code to
own stock (including any number of shares which such person would be entitled to
purchase hereunder) possessing 5% or more of the total combined voting power or
value of all classes of stock of the Company, the maximum number of shares which
such person shall be entitled to purchase pursuant to the Plan shall be reduced
to that number which when added to the number of shares of stock of the Company
which such person is so deemed to own (excluding any number of shares which such
person would be entitled to purchase hereunder), is one less than such 5%.

                                      -3-
<PAGE>   4

                          VII. ELECTION TO PARTICIPATE

         An Eligible Employee may elect to become a Participant in this Plan by
completing a "Stock Purchase Agreement" form prior to the first day of the
Purchase Period. In the Stock Purchase Agreement, the Eligible Employee shall
authorize regular, "after tax" payroll deductions from his Compensation subject
to the limitations in Section VIII below. Purchase rights granted to Eligible
Employees who fail to authorize payroll deductions will automatically lapse. If
a Participant's payroll deductions allow him to purchase fewer than the maximum
number of shares of Common Stock to which his purchase rights entitle him, the
purchase rights with respect to the shares which he does not purchase will lapse
as of the last day of the Purchase Period.

         The execution and delivery of the Stock Purchase Agreement as between
the Participant and the Company shall be conditioned upon the compliance by the
Company at such time with Federal (and any applicable state) securities laws.

                            VIII. PAYROLL DEDUCTIONS

         An Eligible Employee may authorize payroll deductions from his
Compensation for each payroll period of a specified percentage of such
Compensation, not less than 1.0% and not more than 25%, in multiples of 1.0%.

         The amount of payroll deduction shall be established at the beginning
of a Purchase Period and may not be altered, except for complete discontinuance
under Section XI, XIII or XIV hereunder.

                      IX. EMPLOYEE STOCK PURCHASE ACCOUNT
                         AND TRUST ADMINISTRATION OPTION

         An Employee Stock Purchase Account will be established for each
Participant in the Plan. Payroll deductions made under Section VIII will be
credited to the individual Accounts. No interest or other earnings will be
credited to a Participant's Account and the assets of all such Accounts shall
remain general assets of the Company until such assets are used to purchase
Common Stock in accordance with Section X hereunder.

                             X. PURCHASE OF SHARES

         If, as of any Exercise Date, there is credited to the Account of a
Participant an amount at least equal to the purchase price of one share of
Common Stock for the current Purchase Period, as determined in Section V, the
Participant shall buy and the Company shall sell at such price the largest
number of whole shares of Common Stock which can be purchased with the amount in
his Account.

                                      -4-

<PAGE>   5

         Any balance remaining in a Participant's Account at the end of a
Purchase Period will be carried forward into the Participant's Account for the
following Purchase Period. In no event will the balance carried forward be equal
to or exceed the purchase price of one share of Common Stock as determined in
Section V above. Notwithstanding the foregoing provisions of this paragraph, if
as of any Exercise Date the provisions of Section XV are applicable to the
Purchase Period ending on such Exercise Date, and the Committee reduces the
number of shares which would otherwise be purchased by Participants on such
Exercise Date, the entire balance remaining credited to the Account of each
Participant after the purchase of the applicable number of shares of Common
Stock on such Exercise Date shall be refunded to each such Participant. Except
with respect to a Purchase Period for which the Trust Administration Option has
been elected, no refund of an Account balance made pursuant to the Plan shall
include any amount in respect of interest or other imputed earnings.

         Anything herein to the contrary notwithstanding, no Participant may, in
any calendar year, purchase a number of shares of Common Stock under this Plan
which, together with all other shares of stock of the Company and its
Subsidiaries which he may be entitled to purchase in such year under all other
employee stock purchase plans of the Company and its Subsidiaries which meet the
requirements of Section 423(b) of the Code, have an aggregate Fair Market Value
(measured as of the first day of each applicable Purchase Period) in excess of
$25,000. The limitation described in the preceding sentence shall be applied in
a manner consistent with Section 423(b)(8) of the Code.

                                 XI. WITHDRAWAL

         A Participant may withdraw from the Plan at any time prior to the
Exercise Date of a Purchase Period by filing a notice of withdrawal. Upon a
Participant's withdrawal, the payroll deductions shall cease for the next
payroll period and the entire amount credited to his Account shall be refunded
to him. Any Participant who withdraws from the Plan may again become a
Participant hereunder at the start of the next Purchase Period in accordance
with Section VII.

                      XII. ISSUANCE OF STOCK CERTIFICATES

         The shares of Common Stock purchased by a Participant shall, for all
purposes, be deemed to have been issued and sold at the close of business on the
Exercise Date. Prior to that date, none of the rights or privileges of a
stockholder of the Company shall exist with respect to such shares. Stock
certificates shall be registered either in the Participant's name or jointly in
the names of the Participant and his spouse, as the Participant shall designate
in his Stock Purchase Agreement. Such designation may be changed at any time by
filing notice thereof. Certificates representing shares of purchased Common
Stock shall be delivered promptly to the Participant following issuance.
Notwithstanding any provision hereof to the contrary, no shares of Common Stock
shall be issued, sold, registered or delivered pursuant to this Section XII or
otherwise under the Plan unless such issuance, sale, registration or delivery
shall comply with all relevant provisions of law, including, without limitation,
the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, and the requirements of any

                                      -5-

<PAGE>   6

stock exchange upon which the shares of Common Stock may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

                          XIII. TERMINATION OF SERVICE

         (a) Upon a Participant's Termination of Service for any reason other
than death or voluntary termination of employment on or after attaining age 55
("Retirement"), no payroll deduction may be made from any Compensation due him
as of the date of his Termination of Service and the entire balance credited to
his Account shall be automatically refunded to him.

         (b) Upon a Participant's Retirement, no payroll deduction shall be made
from any Compensation due him as of the date of his retirement. Such a
Participant may, prior to Retirement, elect:

                  (1) to have the entire amount credited to his Account as of
         the date of his Retirement refunded to him, or

                  (2) to have the entire amount credited to his Account held
         therein and utilized to purchase shares on the Exercise Date as
         provided in Section X and in accordance with all applicable
         requirements of the Code relating to the Plan.

         (c) Upon the death of a Participant, no payroll deduction shall be made
from any Compensation due him at time of death, and the entire balance in the
deceased Participant's Account shall be paid to the Participant's designated
beneficiary, or otherwise to his estate.

                    XIV. TEMPORARY LAYOFF, AUTHORIZED LEAVE
                             OF ABSENCE, DISABILITY

         Payroll deductions shall cease during a period of absence without pay
from work due to a Participant's temporary layoff, authorized leave of absence,
disability or for any other reason. If such Participant shall return to active
service prior to the Exercise Date for the current Purchase Period, payroll
deductions shall be resumed in accordance with his prior authorization.

         If the Participant shall not return to active service prior to the
Exercise Date for the current Purchase Period, the balance of his Stock Purchase
Account will be used to purchase shares on the Exercise Date as provided in
Section X and in accordance with all applicable requirements of the Code
relating to the Plan, unless the Participant elects to withdraw from the Plan in
accordance with Section XI.

                 XV. PROCEDURE IF INSUFFICIENT SHARES AVAILABLE

         In the event that on any Exercise Date the aggregate funds available
for the purchase of shares of Common Stock pursuant to Section X hereof would
result in purchases of shares in excess of the number of shares of Common Stock
then available for purchase under the Plan, the

                                      -6-

<PAGE>   7

Committee shall proportionately reduce the number of shares which would
otherwise be purchased by each Participant on the Exercise Date in order to
eliminate such excess, and the provisions of the second paragraph of Section X
shall apply.

                          XVI. RIGHTS NOT TRANSFERABLE

         The right to purchase shares of Common Stock under this Plan is
exercisable only by the Participant during his lifetime and is not transferable
by him. If a Participant attempts to transfer his right to purchase shares under
the Plan, he shall be deemed to have requested withdrawal from the Plan and the
provisions of Section XI hereof shall apply with respect to such Participant.

                XVII. NO OBLIGATION TO EXERCISE PURCHASE RIGHTS

         Granting of a purchase right under this Plan shall impose no obligation
on an Eligible Employee to exercise such purchase right.

                  XVIII. NO GUARANTEE OF CONTINUED EMPLOYMENT

         Granting of a purchase right under this Plan shall imply no right of
continued employment with the Company for any Eligible Employee.

                                  XIX. NOTICE

         Any notice which an Eligible Employee or Participant files pursuant to
this Plan shall be in writing and shall be delivered personally or by mail
addressed to the Compensation Committee, c/o Controller at Cellomics, Inc., or
such other person or location as may be specified by the Committee.

                            XX. REPURCHASE OF STOCK

         The Company shall not be required to repurchase from any Participant
shares of Common Stock acquired under this Plan.

               XXI. ADJUSTMENT FOR RECAPITALIZATION, MERGER, ETC.

         The aggregate number of shares of Common Stock which may be purchased
pursuant to purchase rights granted hereunder, the number of shares of Common
Stock covered by each outstanding purchase right, and the purchase price thereof
for each such purchase right shall be appropriately adjusted for any increase or
decrease in the number of outstanding shares of Common Stock resulting from a
stock split or other subdivision or consolidation of shares of Common Stock or
for other capital adjustments or payments of stock dividends or distributions

                                      -7-
<PAGE>   8

or other increases or decreases in the outstanding shares of Common Stock
affected without receipt of consideration of the Company.

         Subject to any required action by the stockholders, if the Company
shall be the surviving corporation in any merger, reorganization or other
business combination, any purchase right granted hereunder shall cover the
securities or other property to which a holder of the number of shares of Common
Stock would have been entitled pursuant to the terms of the merger. A
dissolution or liquidation of the Company or a merger or consolidation in which
the Company is not the surviving entity shall cause every purchase right
outstanding hereunder to terminate.

         The foregoing adjustments and the manner of application of the
foregoing provisions shall be determined by the Committee in its sole
discretion. Any such adjustment shall provide for the elimination of any
fractional share which might otherwise become subject to a purchase right.

                           XXII. AMENDMENT OF THE PLAN

         The Board of Directors may, without the consent of the Participants,
amend the Plan at any time, provided that no such action shall adversely affect
purchase rights theretofore granted hereunder, and provided that no such action
by the Board of Directors, without approval of the Company's stockholders, may:

         (a) increase the total number of shares of Common Stock which may be
purchased by all Participants, except as contemplated in Section XXI;

         (b) change the class of Employees eligible to receive purchase rights
under the Plan;

         (c) decrease the minimum purchase price under Section V;

         (d) extend a Purchase Period hereunder; or

         (e) extend the term of the Plan.

                       XXIII. INTERNATIONAL PARTICIPANTS

         With respect to Eligible Employees who reside or work outside the
United States of America, the Committee may, in its sole discretion, amend the
terms of the Plan with respect to such Eligible Employees in order to conform
such terms with the requirements of local law.

                             XXIV. TERM OF THE PLAN

         This Plan shall become effective as of the Effective Date upon its
adoption by the Board of Directors, provided that it is approved at a duly-held
meeting of stockholders of the Company, by an affirmative majority of the total
votes present and voting thereat, within 12 months after the earlier of the
