                       KEY EMPLOYEE NON-COMPETE AGREEMENT

         THIS KEY EMPLOYEE NON-COMPETE AGREEMENT IS MADE AS OF THE ___________
between Cellomics, Inc., ("Cellomics") and _________________ ("Employee") an
individual residing in ___________________, _______________________________.

         WHEREAS, Employee will be engaged by Cellomics, in a position of trust
and confidence in which Employee will learn of, have access to, and develop
confidential trade secret and other proprietary Information of Cellomics; and

         WHEREAS, Cellomics desires to protect its rights in such confidential,
trade secret and other proprietary Information and to impose certain
restrictions upon Employee's ability to compete with the business of the
Company;

NOW THEREFORE, Cellomics and Employee, in consideration for Cellomics' offer of
employment to Employee, intending to be legally bound, agree as follows:

1.       POSITION AND RESPONSIBILITIES

         1.1.     Employee shall serve and shall perform such duties at such
                  place or places as the Company shall designate,

         1.2.     Employee will, to the best of Employee's ability, devote
                  Employee's full time and best efforts to the performance of
                  Employee's duties hereunder and to the business and affairs of
                  the Company.

         1.3.     Employee will duly, punctually and faithfully perform and
                  observe any and all rules and regulations that the Company may
                  now or shall hereafter establish governing the conduct of its
                  business.

2.       TERM OF EMPLOYMENT

         2.1      The initial term of Employee's employment shall be one (1)
                  year, commencing with the date hereof. Thereafter, this
                  agreement will be extended automatically for one (1)
                  additional year from the date hereof, unless the Company
                  notifies Employee in writing, not later than ninety days (90)
                  preceding the end of the first year, that the agreement will
                  not be extended.

         2.2      The Company shall have the right, on written notice to
                  Employee, to terminate Employee's employment:

                  (a)      immediately for cause, or

                  (b)      at any time without cause provided the Company shall
                           be obligated to pay to Employee as severance pay an
                           amount equal to 3 months' basic salary, less
                           applicable taxes and other required withholdings and
                           any amount

<PAGE>   2

                           Employee may owe to the Company, payable in equal
                           monthly installments on the last day of each month
                           commencing the last day of the month following the
                           date of termination.

         2.3      For purposes of Section 2.2, the term "cause" shall include
                  (i) Employee's failure or refusal to render services to the
                  Company in accordance with Employee's obligations under this
                  Agreement, including Employee's voluntary termination of
                  employment; (ii) the commission by Employee of an act of fraud
                  or embezzlement against the Company or the commission by
                  Employee of any other action with the intent to injure the
                  Company; or (iii) an act of moral turpitude by Employee which
                  is materially detrimental to the business of the Company; or
                  (iv) Employee's having been convicted of a felony other than
                  traffic offenses which do not bring Employee or the Company
                  into disgrace or disrepute.

3.       COMPENSATION. The Company shall pay to Employee for the service to be
         rendered hereunder a basic salary at an annual rate of $___________,
         subject to increase in accordance with the policies of the Company, as
         determined by its Board of Directors, from time to time, payable in
         installments in accordance with Company policy. Employee shall also be
         entitled to all rights and benefits for which Employee shall be
         eligible under deferred bonus, pension, group insurance, profit-sharing
         or other company benefits which may be in force from time to time and
         provided to Employee or for the Company's employees generally.

4.       OTHER ACTIVITIES DURING EMPLOYMENT

         4.1      Except with the prior written consent of the Company's Board
                  of Directors or as described on Exhibit A hereto, Employee
                  will not during the term of this Agreement undertake or engage
                  in any other employment, occupation or business enterprise
                  other than one in which Employee is an inactive investor. This
                  provision shall not be deemed to preclude membership in
                  professional societies, lecturing or the acceptance of
                  honorary positions, that are in any case incidental to
                  Employee's employment by the Company and which are not adverse
                  or antagonistic to the Company, its business or prospects,
                  financial or otherwise.

         4.2      Except as permitted by Section 4.3, Employee will not acquire,
                  assume or participate in, directly or indirectly, any
                  position, investment or interest adverse or antagonistic to
                  the Company, its business or prospects, financial or
                  otherwise, or take any action towards any of the foregoing.

         4.3      During the term of Employee's employment by the Company,
                  except on behalf of the Company or its subsidiaries, Employee
                  will not directly or indirectly, whether as an officer,
                  director, Employee, stockholder, partner, proprietor,
                  associate, representative, or otherwise, become or be
                  interested in any other person, corporation, firm, partnership
                  or other entity whatsoever which directly competes with the
                  Company, in any part of the world, in any line of business
                  engaged in (or which the Company has made plans to be engaged
                  in) by the Company; provided however, that anything above to
                  the contrary notwithstanding, Employee may

                                   Page 2 of 7

<PAGE>   3

                  own, as an inactive investor, securities of any competitor
                  corporation, so long as Employee's holdings in any one such
                  corporation shall not in the aggregate constitute more than
                  one percent (1%) of the voting stock of such corporation.

5.       FORMER EMPLOYMENT

         5.1      Employee represents and warrants that Employee's employment by
                  the Company will not conflict with and will not be constrained
                  by any prior employment or consulting agreement or
                  relationship. Subject to Section 5.2, Employee represents and
                  warrants that Employee does not possess confidential
                  information arising out of prior employment which, in
                  Employee's best judgment, would be utilized in connection with
                  Employee's employment by the Company in the absence of Section
                  5.2.

         5.2      If, in spite of the second sentence of Section 5.1, Employee
                  should find that confidential information belonging to any
                  former employer might be usable in connection with the
                  Company's business, you will not intentionally disclose to the
                  Company or use on its behalf any confidential information
                  belonging to any of Employee's former employers; but during
                  Employee's employment by the Company Employee will use in the
                  performance of Employee's duties all information which is
                  generally known and used by persons with training and
                  experience comparable to Employee's own and all information
                  which is common knowledge in the industry or otherwise legally
                  in the public domain.

6.       EMPLOYEE INNOVATION AND PROPRIETARY INFORMATION. Employee agrees to be
         bound by the provisions of the Proprietary Information and Property
         Agreement made as of _________________________ by and between Employee
         and the Company (the "Proprietary Information and Property Agreement").

7.       POST-EMPLOYMENT ACTIVITIES

         7.1      As a result of Employee's position with the Company, Employee
                  will have access to significant confidential and proprietary
                  information of the Company. In addition, the Company has
                  agreed to impose certain restrictions upon Employee's ability
                  to compete with the business of the Company. Employee
                  understands and acknowledges that these restrictions are fair
                  and reasonable given, among other things, the worldwide market
                  for the Company's products and technologies. Based on the
                  foregoing, and in consideration thereof and of the payments to
                  be made to Employee by the Company pursuant to this Agreement,
                  until twelve (12) months after the termination of Employee's
                  employment with the Company, absent the Company's prior
                  written approval, Employee will not directly or indirectly:

                  (a)      engage in activities for, nor render services to, any
                           firm or business organization which directly competes
                           with the Company or any Subsidiary in any line of
                           business engaged in by the Company or any Subsidiary
                           (or which the Company or any Subsidiary has made
                           plans to be engaged in), whether now existing or
                           hereafter established, nor shall Employee engage

                                   Page 3 of 7

<PAGE>   4

                           in such activities nor render such services to any
                           other person or entity engaged or about to become
                           engaged in such activities to, for, or on behalf of,
                           any such firm or business organization;

                  (b)      solicit Employees of the Company or any Subsidiary to
                           leave its employ;

                  (c)      offer or cause to be offered employment to any person
                           who is employed by the Company or any Subsidiary at
                           any time during the six months prior to the
                           termination of Employee's employment with the
                           Company;

                  (d)      entice, induce or encourage any of the Company's or
                           any Subsidiary's other Employees to engage in any
                           activity which, were it done by you, would violate
                           any provision of this Section 7; or

                  (e)      otherwise attempt to interfere with or disrupt the
                           business or activities of the Company or any
                           Subsidiary.

         7.2      Upon Employee's written request to the Company specifying the
                  activities proposed to be conducted by you, the Company may in
                  its discretion give Employee written approval(s) to personally
                  engage in any activity or render services referred to in
                  Section 7.1 upon receipt of written assurances (satisfactory
                  to the Company and its counsel) from Employee and from
                  Employee's prospective employer(s) that the integrity of the
                  Proprietary Information Agreement and the provisions of
                  Section 7.1 will not in any way be jeopardized or violated by
                  such activities, provided the burden of so establishing the
                  foregoing to the satisfaction of the Company and said counsel
                  shall be upon Employee and Employee's prospective employer(s).

8.       REMEDIES. Employee's duties under the Proprietary Information Agreement
         and Section 7 shall survive termination of Employee's employment with
         the Company. Employee acknowledges that a remedy at law for any breach
         or threatened breach by Employee of the provisions of the Proprietary
         Information Agreement or Section 7 would be inadequate and Employee
         therefore agrees that the Company shall be entitled to injunctive
         relief in case of any such breach or threatened breach.

9.       POST EMPLOYMENT EARNINGS

         9.1      If after conscientious effort (which the Company may ask
                  Employee to establish to its reasonable satisfaction), during
                  any period in which Employee is subject to the restrictions of
                  Section 7.1, Employee is unable primarily due to such
                  restrictions to obtain a position comparable to that last held
                  by Employee with the Company, and which, together with any
                  consulting fees then being paid to Employee by the Company,
                  shall be as remunerative as Employee's monthly remuneration
                  with the Company when Employee's employment terminated
                  (hereinafter Employee's "Remuneration"), then, the Company
                  shall (subject to Section 9.3) pay to Employee monthly, as an
                  additional consulting fee or otherwise, a sum (the
                  "Guarantee") such that Employee's then monthly remuneration
                  shall be equal to Employee's Remuneration. No payment shall be

                                   Page 4 of 7

<PAGE>   5

                  made pursuant to this Section 9.1 with respect to any period
                  for which Employee is receiving severance pay pursuant to
                  Section 2.2(b).

         9.2      Employee shall notify the Company in writing within 15 days
                  after any calendar month as to whether Employee seeks payment
                  of the Guarantee under Section 9.1. Employee must establish
                  the amount of such Guarantee sought to the Company's
                  reasonable satisfaction, whereupon the Company shall promptly
                  (and, in any event, within 15 days of receipt of Employee's
                  notification) pay to Employee the amount of the Guarantee so
                  established.

         9.3      The Company at any time may, upon 90 days' written notice,
                  notify Employee that it prospectively shall not make any
                  further payments of the Guarantee, whereupon Employee shall
                  thenceforth cease to be bound by any of the restrictions of
                  Sections 7.1 or 7.2. All prohibitions of the Proprietary
                  Information Agreement shall survive the Company's decision
                  under this Section 9.3 not to continue the Guarantee.

10.      ASSIGNMENT. This Agreement and the rights and obligations of the
         parties hereto shall bind and inure to the benefit of any successor or
         successors of the Company by reorganization, merger or consolidation
         and any assignee of all or substantially all of its business and
         properties, but, except as to any such successor or assignee of the
         Company, neither this Agreement nor any rights or benefits hereunder
         may be assigned by the Company or you.

11.      INTERPRETATION. In case any one or more of the provisions contained in
         this Agreement shall, for any reason, be held to be invalid, illegal or
         unenforceable in any respect, such invalidity, illegality or
         unenforceability shall not affect the other provisions of this
         Agreement, and this Agreement shall be construed as if such invalid,
         illegal or unenforceable provision had never been contained herein. If,
         moreover, any one or more of the provisions contained in this Agreement
         shall for any reason be held to be excessively broad as to duration,
         geographical scope, activity or subject, it shall be construed by
         limiting and reducing it, so as to be enforceable to the extent
         compatible with the applicable law as it shall then appear.

12.      NOTICES. Any notice which the Company is required or may desire to give
         to Employee shall be given to Employee by personal delivery or
         registered or certified mail, return receipt requested, addressed to
         Employee at the address of record with the Company, or at such other
         place as Employee may from time to time designate in writing. Any
         notice which Employee is required or may desire to give to the Company
         hereunder shall be given by personal delivery or by registered
         certified mail, return receipt requested, addressed to the Company at
         its principal office, or at such other office as the Company may from
         time to time designate in writing. The date of personal delivery or the
         dates of mailing any such notice shall be deemed to be the date of
         delivery thereof.

13.      WAIVERS. If either party shall waive any breach of any provision of
         this Agreement, he or it shall not thereby be deemed to have waived any
         preceding or succeeding breach of the same or any other provision of
         this Agreement.

         enforced in accordance with, the laws of the Commonwealth of

party, in writing, on a timely basis, of any such claim of infringement, and

such claim at its own expense, and provided, further, that no compromise thereof
shall be entered into without consent of the owner party.

injurious to the owner of the INFORMATION.

         10.2 The disclosure of the INFORMATION is solely for the purpose of the
furtherance of the development, marketing and sale of the contemplated products
and services described herein.

         10.3 Each party understands that the disclosing party considers the

<PAGE>   21

         10.5 The term "INFORMATION" shall not include, and the parties shall
not have any obligations of confidence or non-disclosure with respect to:

         A. information that is in the public domain at the time of its

         violation of any obligation of confidence assumed hereunder;

         B. information received from a third party without violation of an
         obligation of confidence to the transmitting party; or

         C. information which the recipient party can show to have been in its
         possession at the time of transmittal; or

         D. information which the recipient party can show to have been

         pursuant to judicial action or the legal and enforceable request of a
         U.S. government agency, provided that the transmitting party is

         provided that the recipient party cooperates with the

                                      -21-

<PAGE>   22

         transmitting party in the event that the transmitting party seeks a
         protective order or other appropriate remedy to prevent disclosure of
         such information.

         10.6 If either party believes it essential to disclose any INFORMATION
to a third party, the party wishing to disclose will first advise the other
party what INFORMATION is to be disclosed, to whom it is to be disclosed and the
purpose therefor. The party wishing to disclose will first obtain the other
party's written permission to make the disclosure before making such disclosure,
which permission may not be unreasonably withheld. The requesting party also
agrees to require the third party recipient of the INFORMATION to acknowledge
that such INFORMATION is confidential, to hold the INFORMATION confidential for
the benefit of the disclosing party, and to sign a copy of a protective
agreement, naming the disclosing party as a third-party beneficiary having the
right to enforce the Agreement against the third party.

         10.7 All INFORMATION, where possible, shall be transferred from each
party to the other in written form, and shall bear a conspicuous mark
designating such INFORMATION to be confidential. Additionally, any INFORMATION
transferred from each party to the other in an oral or other non-permanent or
non-readable form, such as in a computer communication, shall be summarized in a
brief memorandum which shall also bear a conspicuous mark designating such
INFORMATION to be confidential. Furthermore, all INFORMATION transferred in
tangible form shall be returned to the disclosing party upon request and/or at
the termination of this Agreement.

stemming therefrom, except as specifically provided herein.

         10.9 Each party agrees that if it or any of its employees, partners or
other business associates breaches any condition of this Agreement relating to
the protection of proprietary or confidential rights or information, the owner
of such right or information will be entitled to, in addition to all other
remedies available, an immediate injunction prohibiting the party in breach of
its obligations, or its employees, partners or other business associates, from
committing any further breach of the Agreement.
