                  (5) "Subcontractor" means a supplier, materialman, distributor
or vendor at any level below the prime contractor whose contractual obligation
to perform results from, or is conditioned upon, award of the prime contract and
who is performing any part of the work or other requirement of the prime

                  (6) "Supplies" means all property, except land and interests

by the DoD if, for example, the contract documentation contains a reference to a
DoD contract number or a military destination.
                           (ii) "Supplies" includes (but is not limited to)
public works; buildings and facilities; ships; floating equipment and vessels of
every character, type and description, with parts, subassemblies, accessories

contract. The Contractor and its subcontractors may request that the Contracting

to the sailing date necessary to meet its delivery schedules. The Contracting
Officer will process requests submitted after such date(s) as expeditiously as
possible, but the Contracting Officer's failure to grant approvals to meet the
shipper's sailing date will not of itself constitute a compensable delay under
this or any other clause of this contract. Requests shall contain at a

                  (2) Required shipping date.

U.S.-flag vessels, including points of contact (with names and telephone
numbers) of at least two (2) U.S.-flag carriers contacted. Copies of telephone
notes, telegraphic and facsimile messages or letters will be sufficient for this
purpose.

     2.4   During the first year of the term of this agreement ("First Year"),
           the Parties agree to work in accordance with the Workplan set forth
           in Appendix A, with the goal to have a Prototype of the Cassette by
           the first anniversary of the Effective Date. The goal during the [*]
           is to optimize the Cell Plate and Microfluidic Plate design and
           interfacing to enable fabrication of a functional Cassette. This
           Cassette is intended to have the specifications for and serve as a
           testbed for a [*]. In addition, it is intended that the Parties will
           use this Cassette as a working Prototype in a TAP program.
           Development of the Cassette Prototype will be directed to enable:
           [*]. During the First Year and thereafter, each Party will provide
           written reports with thirty (30) days of the end of each calendar
           quarter of the progress it has made during such quarter and the work
           to be performed in the next quarter and a written summation of the
           work accomplished at the end of each calendar year within thirty (30)
           days of the end of such calendar year.

     2.5.  Notwithstanding the intention to achieve the goals of the Workplan
           for the First Year, it is understood that in order to staff the
           Program, ACLARA and CELLOMICS will be required to hire new personnel
           or transfer existing personnel as they may become available. While
           each Party will act diligently to staff the Program in accordance
           with the Program's needs and available funding, the timing of such
           hires or transfers is not completely within the control of the
           Parties and the schedule of the Workplan may be delayed. At each
           quarterly meeting of the JSC, the accomplishment of the previous
           quarter, and the available funding, committed or to be committed,
           will be evaluated and the Workplan modified, if necessary, in light
           of the circumstances then pertaining.

           2.5.i.  If prior to the occurrence of the Intellectual Property
                   Milestone there appears to either Party to be an insufficient
                   Revenue Source at that time or in the reasonably foreseeable
                   future to support the Program in the amounts required by each
                   Party for its performance, the JSC shall review the situation
                   and report to the respective CEO's its recommendation as to
                   how to proceed within sixty (60) days of notification by
                   either Party that such Party believes there is an
                   insufficient Revenue Source to support the Program. If the
                   CEOs cannot agree within sixty (60) days of receiving

                  notification from the JSC as to how to proceed, either Party
                  may terminate this Agreement upon giving prompt notice of
                  termination to the other Party without obligation to license
                  the other party under the terminating Party's intellectual
                  property. If the Program is terminated for other than material
                  breach prior to the completion of the Intellectual Property
                  Milestone, the parties will negotiate in good faith to allow a
                  continuing party to continue the Program.

         2.5.ii.  Notwithstanding Paragraph 2.5.i, after the Intellectual
                  Property Milestone has been achieved, the terminating Party
                  will be obligated to license the continuing Party under the
                  terminating Party's intellectual property to continue to
                  develop and commercialize the Prototype and Screening System
                  as hereinafter provided. Upon termination by one Party for
                  other than material breach, with the Intellectual Property
                  Milestone having been achieved, the other Party may continue
                  the Program and the terminating Party agrees to enter into
                  negotiations within thirty (30) days of such termination with
                  the other Party over the terms of such license which the
                  terminating Party is obligated to license to the continuing
                  Party under its intellectual property, both background and
                  foreground, on reasonable terms and conditions to make, use
                  and sell Screening Systems substantially conforming to the
                  Screening System which was to be jointly developed.

       2.6   Assuming financing is obtained as required to support the Program
             for the second and third years of the term of this Agreement, or
             such other periods in which the goals of these years are to be
             fulfilled as determined by the JSC, a Screening System will be
             developed, which is intended to offer a complete solution to the
             need for flexibility in Cell-based Assays starting with an initial
             focus on [*]. The Screening System will be designed to have the
             ability to provide a complete portfolio of assays including [*].
             The Screening System will offer a ready-to-use and easy-to-use
             solution for the life scientist and further will promote
             penetration of sophisticated Cell-based Assays HCS in drug
             discovery. The target pharmaceutical customer for the Screening
             System is an entity with significant biological expertise in
             primary screening, a therapeutic group or a specialty such as [*].

       2.7   The development program for [*] of the term of this agreement is
             set forth in Appendix B with the intention of developing a
             Screening System. The 3D Cassette will have a high density plumbing
             architecture for selective addressing of a high density of
             micro-arrayed cells on the Cell Plate. The initial design and
             prototypes will focus on multiples of 96 well patterns in a
             footprint ranging from [*].

                  render this [*] applicable to the Screening System, the JSC
                  may adjust the Workplan accordingly. CELLOMICS will be
                  responsible for Cell Plates, all reagents, assays, and
                  protocols. CELLOMICS will work to ensure that the components
                  which neither Party intends to produce are made available from
                  a third party and are available for commercialization of the
                  Screening System. CELLOMICS will be responsible for the final
                  development and manufacturing of the remaining components of
                  the Screening System.

            4.2.  Manufacturing of the integrated system: The final
                  manufacturing, packaging and delivery of [*] and other
                  Cell-based Assay reagents, Cassettes and Screening Systems to
                  customers will be the responsibility of CELLOMICS. Prior to
                  the initiation of manufacturing of a Cassette, the Parties
                  will enter into a supply agreement in which ACLARA will be
                  responsible for delivering to CELLOMICS, or a third party
                  designated by CELLOMICS, sufficient quantities of Microfluidic
                  Plates for packaging with Cell Plates. Such supply agreement
                  will provide for indemnification of the other Party on
                  conventional terms for the intentional, willful, or negligent
                  act or failure to act of one Party, giving rise to a claim
                  against the other Party. The supply terms for ACLARA's
                  delivery to CELLOMICS shall be conventional, giving due regard
                  to

          Statements made by CELLOMICS concerning ACLARA shall be subject to
          review and approval by ACLARA, which approval shall not be
          unreasonably withheld.

5.   Revenue Sharing

     5.1  During the development and commercialization phase, the money obtained
          from third parties from a Revenue Source shall be divided to ensure
          that each Party's expenditure of its own money on a JSC approved
          Workplan is minimized. The exact division of [*] will be decided at
          the time of [*]. The division of TAP fees will be defined by the JCS,
          and approved by the CEO of both Parties, and written into a separate
          agreement between CELLOMICS and ACLARA before a TAP agreement is
          consummated. Funding from a collaborator other than the other Party
          will primarily be used for the purposes of the collaboration.

     5.2  Not later than the end of [*] the Parties shall initiate negotiations
          as to the division of income resulting from the sales of Screening
          Systems and its components. The division of the income will first be
          considered by the JSC with final approval of the CEO's from CELLOMICS
          and ACLARA. ACLARA shall receive from CELLOMICS [*] and a reasonable
          profit margin for items manufactured or supplied by ACLARA;
          Considerations in determining the division of remaining

          income shall be the financial contribution of each of the Parties,
          except to the extent the Parties have been reimbursed any portion of
          their contribution by a Revenue Source, the novelty of their
          contributions, the value of the intellectual property that protects
          components of the Screening Systems, the competitive advantages
          provided by the contributions of the two Parties, the responsibilities
          of the two Parties in manufacturing, marketing and supporting the
          ongoing expenditures, the risks involved with the continuing
          investments, and the like. The income to ACLARA shall not be less than
          a reasonable royalty on patents and know-how contributed by ACLARA
          with the base being Screening Systems and components, where the
          royalty may vary as to whole Screening Systems and as to individual
          disposable Screening System components. Royalty shall not be paid
          twice for the same component of the Screening System. If there is no
          agreement between the Parties, the matter shall be given to mediation
          as provided for hereinafter. The exact mechanism for delivering the
          value to the Parties will be defined as the program proceeds toward
          commercialization. It may involve strict revenue sharing, licensing,
          royalties or some combination that will be defined by the JSC.

6.   Public Relations

     6.1  All press releases created by an originating Party shall be submitted
          to the other Party for approval and shall not be released without the
          prior written approval of the other Party. In the event of a dispute,
          the matter shall be submitted to the CEOs of the Parties and if the
          issue cannot be reconciled, there shall be no press release containing
          disputed subject matter.

     6.2  Prior to commercial introduction of a Screening System, all public
          presentation relating to this Program, not already made public,

          and conditions, if at the time of filing of a patent application for
          such invention, ACLARA agrees to pay [*] of the out-of-pocket costs of
          the filing, prosecution and maintenance of such application,
          continuing applications, foreign analogs, and Letters Patent issuing
          thereon.

     7.4  Licensing of Foreground technology. Technical know-how and patent
          rights developed as part of the Program shall be available on
          reasonable terms and conditions after termination of this Agreement in

<PAGE>   12

               will be considered final after reduction to writing and
               attachment to the Agreement. Significant alterations to the
               Workplan must be approved by the CEO of both Parties. The JSC
               shall have the authority to recommend alterations or amendments
               to this Agreement, which shall not become final until reduced to
               writing and signed by the CEO of each of the Parties. Except as
               otherwise expressly provided herein, decisions of the JSC will be
               made by consensus.

          9.2  Dispute resolution. Should disputes arise, the Parties agree to
               negotiate in good faith to resolve the disputes. Disputes that
               cannot be resolved by the JSC within a reasonable period shall be
               submitted to the CEOs of the Parties. If agreement is still not
               reached, the Parties agree to submit disputes to mediation in
               accordance with the section 9.3, "Mediation", prior to seeking
               any other remedy.

          9.3  Mediation. If the Parties are unable to resolve by negotiation
               within forty-five days of the disputing Party's written request
               for dispute resolution (or such other time period expressly set
               forth in this Agreement), or if the Parties fail to meet within
               twenty (20) days after such notice, the Parties shall endeavor to
               settle the dispute by mediation administered by the American
               Arbitration Association ("AAA") pursuant to the Commercial
               Mediation Rules of the AAA the time of submission prior to
               resorting to any other remedy. Mediation shall be held in a
               location to be decided later. The mediator appointed to assist
               the Parties must possess such credentials as qualify said
               mediator as (1) either an expert in the field being mediated or
               (2) at a minimum as reasonably familiar with the industries and
               specific applications as will enable the mediator to quickly
               understand and assist the Parties in dealing with the issues that
               are in dispute. Notwithstanding the foregoing, to the extent that
               any controversy or claim hereunder gives rise to a prayer for
               injunctive relief, equitable action or specific performance, the
               aggrieved Party shall have the right to commence such an action
               in any court of competent jurisdiction.
