            (vii) Completion criteria, quality testing, and reports.

            (viii)Payments to be made.

      3.3.  TYPES OF WORK.  It is expected that the projects that Summus may
undertake pursuant to one (1) or more Work Statements will initially relate to:

      (a)   Phase I, Digital Image Consultation and Delivery of Base Technology

            (i)   Deliverables will generally include certain software based on
                  Summus' Wavelet Image Technology and certain enhancements
                  specifically related to the ADLabs' anatomical pathology
                  market segment.

            (ii)  Deliverables are planned to include, 12 or 14-bit RGB SDK,
                  registration and stitching of multiple images, and an
                  application interface to examine the slides at multiple
                  resolutions including a thumbnails and zoom functions.

            (iii) Early deliverables in Phase I are envisioned to be prototypes
                  of the foregoing to be used to identify and document final
                  requirements on functions and user interfaces. The Phase I
                  Work Statement shall specify the consulting fee payments and
                  the payment schedule for the Phase I Work.

      (b)   Phase II, Object Recognition and Slide Automation

            (i)   In this Phase, Summus will provide enhancements to its base
                  Wavelet Image Technology for purpose of a pattern recognition
                  from a catalogue of images developed to allow the ADLabs to
                  incorporate the delivered code into its ADPhase and ADSoft
                  products, end to end system consisting of object/pattern
                  recognition and database searching.

            (ii)  The Phase II Work Statement shall specify the consulting fee
                  payments and the payment schedule for the Phase II Work.

      (c)   Phase III, Multiple Spectrum Analysis and Diagnostics
<PAGE>   4
            (i)   In Phase III Summus will develop enhancements to its base
                  Wavelet Technology to assist ADLabs in developing its
                  ADBioScan product, which is envisioned to be a diagnostic tool
                  capable of multi-spectrum pattern recognition, imaging
                  cataloging and management, and multiple category searching.

            (ii)  Specifics of the Phase III effort will be delineated in the
                  specific Work Statement.

      3.4. ADOPTION OF WORK STATEMENTS; CHANGES. Work Statements, changes to
Work Statements, and amendments to this Agreement shall be effective only if in
a writing accompanied by dated signatures of authorized representatives of both
parties. Replacement pages initialed and dated by authorized representatives of
both parties will be sufficient for that purpose. Unless otherwise indicated, a
change or amendment shall be effective on the date signed by both parties.

                                     Section 4
                                    PERFORMANCE

      4.1. REASONABLE EFFORTS. The parties agree to use commercially reasonable
effort to perform the tasks assigned and to complete the Phase Development
Services specified in each applicable Work Statement. All services will be
rendered in a workmanlike manner by personnel having a level of skill
commensurate with their responsibilities.

      4.2. TARGET DATES. Scheduled performance dates are estimates only. Both
parties recognize such dates are dependent on development, resource
availability, funding, assistance, and other factors that may cause dates to
shift or interfere with completion. However, each Work Statement shall set forth
a date for completion of the Phase Development Services for a Phase and such
date shall be applicable for purposes of determining satisfaction of the
condition for timely completion of the Phase Development Services for any Phase
as contemplated in the Stock Warrant Agreement.

      4.3. THIRD-PARTY RESOURCES. References to Deliverable or the assignment to
Summus of responsibility for particular Phase Development Services shall not be
construed to make Summus responsible for securing any related Intellectual
Property Rights that may be owned or retained by third parties, unless (a) the
applicable Work Statement expressly makes Summus responsible for securing those
Intellectual Property Rights in the manner contemplated by Section 5 below or
(b) Summus has reason to believe at the time the Work Statement is
<PAGE>   5
executed that third party Intellectual Property Rights will be needed to avoid
infringement in ADLabs conduct of its Business using the Summus Code as modified
in accordance with the Work Statement. A statement or reference in a Work
Statement that Summus is responsible for obtaining third-party resources,
including services, equipment, facilities, or Intellectual Property Rights, is
subject to the availability of those resources. If during the rendering of Phase
Development Services under a Work Statement Summus has reason to believe that
third party Intellectual Property Rights will be needed to avoid infringement in
ADLabs conduct of its Business using the Summus Code as modified in accordance
with the Work Statement, Summus shall promptly notify ADLabs thereof in writing.

                                    Section 5
                               RESOURCES PROVIDED

      A Work Statement may state that Summus or ADLabs is responsible for
obtaining certain resources. Examples of resources that may be provided by
either party for use in work done under this Agreement include:

      (a)   Services, including development services, engineering services,
            training, manufacturing services, or administrative support.

      (b)   Software (programming and documentation) previously in existence,
            where the Intellectual Property Rights are owned by one of the
            parties.

      (c)   Software (programming and documentation) previously in existence,
            where the Intellectual Property Rights are owned by third parties
            and limited rights to such Software have been obtained by one of the
            parties under license.

            Note: In order to comply with restrictions imposed by third-party
            licensors, either party shall be entitled to limited disclosure to
            the other party of such software so that the other party is
            authorized only to provide programming assistance or testing in
            support of the licensed party, pursuant to designs owned or approved
            by the licensed party, under the direct and exclusive supervision
            and control of the licensed party, and with respect to interface
            programming or other development activity of a similarly narrow
            scope. When acting under those terms, the other party obtains no
            license or sublicense to the licensed software and, instead, the
            other party shall constitute solely an independent contractor acting
            for hire with respect to activities of the licensed party under a
            Work Statement.
<PAGE>   6
            Note: Where practical for the completion of the applicable work,
            programming may be provided in whole or in part only in object code
            form.

      (d)   Equipment.

            Unless otherwise agreed, any equipment provided by either party to
            the other party is loaned for use in performing the tasks specified
            in applicable Work Statements and, upon completion of those tasks,
            shall be returned in the same condition as received, fair wear and
            tear excepted. Any charges applicable for the loan of such equipment
            shall be set forth in the Work Statement.

            IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF FITNESS
            FOR ANY PARTICULAR PURPOSE OR MERCHANTABILITY. IN NO EVENT SHALL
            SUMMUS BE LIABLE TO ADLABS FOR ANY LOST PROFITS OR OTHER INCIDENTAL
            OR CONSEQUENTIAL DAMAGES RELATING TO THE SUBJECT MATTER OF THIS
            AGREEMENT EVEN IF SUMMUS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
            DAMAGES IN
<PAGE>   10

Statement is itself terminated or performance thereunder is completed.

      11.2. TERM AND TERMINATION OF WORK STATEMENT. Unless otherwise stated in
the applicable Work Statement, the term of the Work Statement shall last until
performance thereunder is completed, except that ADLabs may, at its sole option
and for its own convenience, terminate any or all Work Statements in effect
and/or this Agreement upon sixty (60) days' prior written notice. Upon such
termination, the parties shall inform each other of the extent to which
performance has been completed through such date, and collect and deliver all
work in process. In the event of termination, the parties agree to wind up their
work in a commercially reasonable manner and to preserve and deliver items of
value created prior to termination.

      11.3. TERMINATION OF THIS AGREEMENT.

      (a)   Breach. Should either party commit a material breach of any
            obligation hereunder, except an obligation to make payments, the
            other party, at its option, may terminate this Agreement by sixty
            (60) days' prior notice to the other party. Such notice shall state
            the default upon which termination is based. Notwithstanding such
            notice, termination shall not occur and the defaulting party shall
            not be liable for any further remedy if (i) such default is cured,
            and notice of such cure is sent to the nonbreaching party within
            such sixty day period, or (ii) if such breach is incapable of being
            cured within such period and
<PAGE>   11
            the breaching party presents the nonbreaching party with its plan to
            cure and is diligently executing such plan.

      (b)   Special Grounds for Termination. Notwithstanding any other provision
            of this Agreement, (i) Summus may terminate this Agreement upon
            fifteen days' written notice for nonpayment of fees after the same
            shall have become a past due payment, unless such nonpayment is
            cured within such fifteen (15) day period, and (ii) this Agreement
            shall terminate immediately in the event of any (A) affirmative act
            of insolvency by ADLabs, (B) upon the appointment of any receive or
            trustee to take possession of the properties of ADLabs or upon the
            winding-up, or (C) upon the expiration or termination, for any
            reason, of the Technology License Agreement. In the event of any
            termination set forth in this Section, all rights of ADLabs that
            otherwise would survive expiration or termination shall immediately
            terminate, and Summus shall be entitled to pursue all available
            remedies under contract, copyright, tort, and other applicable law.

      11.4. SURVIVAL. Except as limited by Section 12.3(b) hereof, the
provisions of Sections 8, 9, 10, 11 and 13 shall remain in effect after
termination of this Agreement.

                                   Section 12
                                  MISCELLANEOUS

      12.1. FORCE MAJEURE. Either party shall be excused from delays in
performing or from its failure to perform hereunder to the extent that such
delays or failures result from causes beyond the reasonable control of such
party; provided that, in order to be excused from delay or failure to perform,
such party must act diligently to remedy the cause of such delay or failure.

      12.2. NO AGENCY. This Agreement and the Work Statements do not create any
relationship between the parties hereto other than as independent contractors.

      12.3. SEVERABILITY. If any provision of this Agreement is held to be
invalid, the other provisions will not be affected to the greatest extent
possible consistent with the parties' intent.

      12.4. MULTIPLE COUNTERPARTS. This Agreement may be executed in several
counterparts, all of which taken together shall constitute one single Agreement
between the parties.

      12.5. SECTION HEADINGS; EXHIBITS. The section and subsection headings used
herein are for reference and convenience only, and shall not enter into the
<PAGE>   12
interpretation hereof. The exhibits referred to herein and attached hereto, or
to be attached hereto, including all Work Statements issued hereunder from time
to time, are incorporated herein to the same extent as if set forth in full
herein.

      12.6. COMPLIANCE WITH LAW.

      (a)   Each party agrees to comply with all applicable laws, regulations,
            and ordinances relating to their performance hereunder.

      (b)   Neither party will knowingly export or re-export, directly or
            indirectly, any technical data (as defined by the U.S. Export
            Administration Regulations) produced or provided under this
            Agreement, or export or re-export, directly or indirectly, any
            direct product of such technical data, including software, to a
            destination to which such export or re-export is restricted or
            prohibited by U.S. or non-U.S. law, without obtaining prior
            authorization from U.S. Department of Commerce and other competent
            government authorities to the extent required by those laws.

      12.7. NO WAIVER. No delay or omission by either party hereto to exercise
any right or power occurring upon any noncompliance or default by the other
party with respect to any of the terms of this Agreement shall impair any such
right or power or be construed to be a waiver thereof. A waiver by either of the
parties hereto of any of the covenants, conditions, or agreements to be
performed by the other shall not be construed to be a waiver of any succeeding
breach thereof or of any covenant, condition, or agreement herein contained.
Unless stated otherwise, all remedies provided for in this Agreement shall be
cumulative and in addition to and not in lieu of any other remedies available to
either party at law, in equity, or otherwise.

      12.8. PREVAILING PARTIES. In case of litigation arising out of or in
connection with this License Agreement, the prevailing Party shall be entitled
to recover its reasonable attorneys' fees, costs and expenses from the other
Party.

      12.9. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, without giving effect to
conflicts of laws principles.

      12.10. DISPUTE RESOLUTION. If a dispute arises out of or relates to this
License Agreement or the breach thereof (a "Dispute"), and if the Dispute cannot
be settled through negotiation between the parties for a period not to exceed
sixty (60) days, the parties agree first to try in good faith to settle the
Dispute by mediation administered by the American Arbitration Association under
its Commercial
<PAGE>   13
Mediation Rules before resorting to arbitration, litigation, or some other
dispute resolution procedure.

Notwithstanding anything to the contrary contained in this Section, the parties
hereby preserve, without diminution, certain remedies that any of them may
employ or exercise freely, in connection with or during a Dispute. Each of the
parties shall have the right to proceed in any court of proper jurisdiction to
exercise or prosecute the following remedies, as applicable: (i) obtaining
provisional or ancillary remedies, including injunctive relief, garnishment,
attachment, appointment of a receiver and filing an involuntary bankruptcy
proceeding, and (ii) a judgment obtained by confession of judgment. Preservation
of these remedies does not limit the power of a mediator to grant similar
remedies that may be requested by a party in a Dispute.

      12.11. ENTIRE AGREEMENT. This Agreement and the exhibits annexed hereto,
together with the Work Statements issued from time to time hereunder, the
Confidentiality Agreement dated February 16, 2000, and the Technology License
Agreement and the Stock Warrant Agreement each entered into by the parties
concurrently herewith, constitute the entire agreement between the parties with
respect to the subject matter hereof. No change, waiver, or discharge hereof
shall be valid unless it is in writing and is executed by the party against whom
such change, waiver, or discharge is sought to be enforced.

      12.12. NO ASSIGNMENT. Unless a party's rights and obligations under the
Technology License Agreement have been properly assigned pursuant to the terms
thereof, neither party may, without the prior written consent of the other
party, assign or transfer this Agreement or any obligation incurred hereunder.
If a party has properly assigned its rights and obligations under the Technology
License Agreement, such party may assign its rights and obligations hereunder to
the same assignee as the Technology License Agreement, provided that such
assignee expressly accepts, in writing, the obligations of the assignor
hereunder as if the assignee were a party to this Agreement.
