3.  TESTING PROGRAM.

    3.1   TESTING PROGRAM.  Upon completion of development and production of an
EDS prototype, the parties agree to conduct at least two field trials of EDS
prototypes in accordance with the Testing System Specifications.

    3.2   ACCEPTANCE TESTING PERIOD.  InVision shall have twenty (20) business
days from each respective date on which Astrophysics delivers EDS prototypes to
determine that the prototype substantially conforms to the Specifications (the
'Testing Period').  Within the Testing Period for each EDS prototype developed
hereunder, InVision shall provide Astrophysics with either a written acceptance
of such prototype (an 'Acceptance Notice') or a written statement of any defects
('Error Statement') in such EDS prototype that cause such prototype not to work
substantially in conformance with the Specifications.  An EDS prototype will be
deemed to be accepted by InVision if Astrophysics does not receive either an
Acceptance Notice or Error Statement within the Testing Period for such EDS
prototype.

    3.3   ERROR CORRECTION; RETESTING.  In the event InVision delivers an Error
Statement to Astrophysics, then Astrophysics will use its commercially
reasonable efforts to correct any defects described in such Error Statement and
redeliver a corrected EDS prototype to InVision within thirty (30) business days
of the date of the Error Statement.  InVision shall have twenty (20) business
days from the date such corrected EDS prototype has been delivered to retest
such EDS prototype and determine whether such


                                          10



corrected prototype substantially conforms with the Specifications (the
'Retesting Period').  Within such Retesting Period, InVision shall provide
Astrophysics with either an Error Statement or an Acceptance Notice as to such
corrected prototype.  The corrected EDS prototype will be deemed to have been
accepted and, therefore, will be the final version of such EDS prototype, if
within such Retesting Period Astrophysics does not receive either an Error
Statement or an Acceptance Notice.  Subject to Section 12 below ('Term and
Termination'), this process of testing and redelivering corrected versions of
EDS prototypes as set forth above shall continue until InVision accepts a
particular version of the EDS prototype.  The date of InVision's acceptance of
such prototype shall be the 'Acceptance Date.'

    3.4   After the Parties have engaged in at least three (3) Testing Periods
for a particular EDS Product which is not then accepted by InVision pursuant to
Section 3.2 hereof, the parties agree that any Party then desiring to terminate
this Agreement pursuant to Section 12 hereof shall first try to resolve or
correct  through the Oversight Board any problems serving as a barrier to
Acceptance.  In the event that the problem or problems cannot be resolved or
corrected after the good faith efforts of both Parties, then either Party may
terminate the Agreement and will not incur any penalty for termination.  In such
case, the Parties shall each bear fifty percent (50%) of all Development Costs
incurred by the Parties to date.

4.  PAYMENTS AND TAXES.

    4.1   DEVELOPMENT CONTRIBUTIONS.  Upon the Effective Date hereof, each of
InVision and Astrophysics will provide for in their respective budgets One
Million United States Dollars (U.S. $1,000,000) (together, the 'Development

advance the EDS Technology and capabilities.  Money allocated to the Development
Funds will be spent by each Party in accordance with a development budget to be
developed by the Parties and unanimously approved by the Oversight Board, a
preliminary draft of which budget is attached in summary form hereto as Exhibit
F (the 'Budget')  The Parties agree to negotiate in good faith a definitive
Budget within thirty (30) days from the Effective Date.  Any federal funds
received pursuant to grants sought in accordance with Section 2.5.1 above shall
be added to and treated the same as the Development Funds.

    4.2   RIGHT OF AUDIT.  Each Party shall maintain and retain complete, clear
and accurate records of the allocation and expenditures of their respective
Development Funds during the term of this Agreement and for a period of one (1)
year thereafter.  The form of the records shall be designed and agreed upon by
the Oversight Board.  Within ten (10) days after the end of each calendar
quarter during the term of this Agreement, each Party shall prepare for and
deliver to the Oversight Board a report based upon such records for the quarter
most recently completed.  To ensure compliance with the terms of


                                          11



this Agreement, upon reasonable prior written notice to the other Party, each
Party (the 'Auditing Party') shall have the right to inspect and to audit the
records of the other Party relating to the allocation and expenditure of the
Development Funds by such Party (the 'Audited Party') during reasonable and
normal business hours.  In the event that such an inspection and audit uncovers
any irregularities in the allocations or expenditures of Development Funds, then
the reports shall be corrected accordingly.

    4.3   TAXES.  Each Party agrees to pay and shall be responsible for its own
taxes incurred by or levied upon it in connection with the performance of its
obligations under this Agreement and shall be entitled to claim any applicable
tax credits, deductions or incentives related to the Development Costs expended
by it which are not subject to reimbursement by the other Party; excepting
therefrom sales and use taxes incurred on goods and materials purchase for use
or consumption in the Development Program for the development of the EDS
Products or EDS Technology, the responsibility for which and benefits of shall
be shared equally by the Parties and paid out of the Development Funds.

    4.4   EXCESS.  It is the intention of the Parties that they share equally
the Development Costs.  Each Party shall make commercially reasonable efforts to
control its expenditures of Development Funds in accordance with the Budget.  At
the end of each calendar quarter, each Party will calculate the total amount of
the Development Funds expended by such Party during that quarter.  If one Party,
staying within the Budget during that quarter, has expended more than the Other
Party, the Party which has spent the lesser amount shall reimburse the other
Party for fifty percent (50%) of the expenditure difference so as to equalize
expenditures by both Parties during the Development Program.  All costs or
expenses contained within the Budget and incurred by any Party directly as a
result of its work hereunder in excess of that Party's share of the Development
Funds for which such Party seeks partial reimbursement by the other (not to
exceed fifty percent (50%) of such cost), first shall be authorized by the
Oversight Board upon receipt of itemized statements with any necessary back-up
or explanation attached in writing.  In the event that a Party fails to obtain
the required pre-authorization for any of its costs or expenses, such Party may
still provide an itemized statement together with a written explanation and
back-up documentation justifying the expenditure and if and to the extent that,
in the sole discretion of  the Oversight Board, the Oversight Board determines
that such expenditure or any portion thereof was reasonable or necessary for the
purposes of this  Agreement, then such expense or the approved portion thereof
shall be shared equally by the Parties, and the Party seeking reimbursement
shall be accordingly reimbursed by the other Party.  All other costs or expenses
incurred by any Party shall be borne by the Party incurring them.

5.  NON-INFRINGEMENT WARRANTY; NOTICE OF INFRINGEMENT.

    5.1   CONTRIBUTIONS TO EDS.  InVision and Astrophysics each represents and
warrants to the other that to the best of their knowledge, respectively, their
portions and contributions to the EDS Specifications, the EDS prototype, the EDS
Product and the EDS Documentation will be original creations of the contributing
Party and will not infringe any patent, copyright, trade secret or other
proprietary rights of any third party; that such Party has not previously or
otherwise granted any rights to any third party which conflict with the rights
granted herein; and that such Party has the full power and ability to enter into
this Agreement, to carry out its obligations set forth herein and to grant the
rights granted to the other herein.

    5.2   NOTICE OF THIRD PARTY INFRINGEMENT.  Each Party shall promptly inform
the other Party of each infringement by third parties of the infringed Party's
Technology or of the EDS Technology or EDS Products developed hereunder, which
third party infringement comes to its knowledge or attention during the term of
this Agreement or for a period of one (1) year thereafter.  Each Party shall
render reasonable assistance to the other in defending the infringed Party's
Technology against third parties, but control of such defense and the cost
therefore shall be borne solely by the infringed Party.  In the case of third
party infringement of EDS Technology or EDS Products, the Parties will mutually
determine how to proceed with an enforcement action and which of the Parties
shall control such action.  In such case, the Parties shall share equally the
costs of the enforcement action, including without limitation attorneys' fees
and expenses.  If the Parties cannot agree, then an Arbitrator shall be
appointed in accordance with Section 13 hereof to determine the method of
enforcement and which Party shall control such enforcement action, and shall
also determine how the costs of such enforcement action will be split between
the Parties.  The recovery from the enforcement action will be split in
proportion to the Parties' contribution to the enforcement action's costs
(including without limitation attorneys' fees and expenses).  In the event that
a Party hereto declines to participate in an enforcement action, such Party
agrees, at the participating Party's expense, to join the action as a party
plaintiff and otherwise to cooperate with the enforcement action in any way
reasonably requested by the participating Party.

    5.3   ACKNOWLEDGMENT OF INDEPENDENT DEVELOPMENT; COVENANT NOT TO SUE.  Each

          13.2.1   If a dispute arises between any of the Parties which cannot
be resolved by negotiation or, failing that, by referral to and consideration by
the Oversight Board, then the Parties agree to participate in non-binding
mediation before pursuing any other legal remedies.  The mediation shall be
conducted in San Mateo County, California by United States Arbitration & Mediation Association, Inc., or such other mediation association as the Parties
shall determine within thirty (30) days from the Effective Date, with costs to
be borne equally by the Parties between whom the dispute has arisen.

          13.2.2   If any participating Party is unsatisfied with the results
of such mediation, then the dispute shall be finally determined by arbitration
pursuant to the rules of the California Code of Civil Procedure.  Each Party
involved in the dispute shall appoint one representative reasonably acceptable
to the other involved Parties, and the representatives shall then appoint one
independent arbitrator (the 'Arbitrator') to hear and resolve the dispute, all
within ten (10) business days of receipt by any Party of written notice that the
matter has been referred to arbitration.

          13.2.3   The Arbitrator shall, without prejudice to the generality
of his or her powers, have the power to amend this  Agreement, together with any
of its Exhibits, Attachments or Schedules, so that it accurately reflects the
true agreement made by the Parties, to direct such measurements, tests and/or
valuations as may in the Arbitrator's opinion be desirable in order to determine
the rights of the Parties and to ascertain and award any sum which ought to have
been the subject of or included in any payment and to open up, review and revise
any account, opinion, decision, requirement, report or notice and to determine
all matters in dispute which shall have been submitted to the Arbitrator in the
same manner as if no such account, opinion, decision, requirement, report or
notice had been given previously.

          13.2.4   Subject to subparagraph 13.2.5 below, the award of the
Arbitrator shall be final and binding upon the Parties, and judgment upon the
award rendered may be entered into any court having jurisdiction thereof.

          13.2.5   The Parties agree and consent that any Party involved in a
particular dispute for which an Arbitrator has rendered an award:

                   (a)  May appeal to a court of law having jurisdiction
thereover any question of law arising out of an award made in an arbitration
pursuant to this Section 13,

                   (b)  May appeal to a court of law having jurisdiction
thereover to determine any question of law arising in the course of any referral
to arbitration made pursuant to this Section 13; and

                   The Parties agree that any such court shall have the
authority and jurisdiction to determine any such question or questions of law.


                                          21



          13.2.6   If before making his or her final award, the Arbitrator
dies or otherwise ceases to act as the Arbitrator, the representatives of the
Parties involved in the dispute shall promptly appoint a further Arbitrator.  No
such further Arbitrator shall be entitled to disregard any direction of the
previous Arbitrator except (i) to the extent that the previous Arbitrator had
power to do so under the Rules of the American Arbitration Association, (ii)
with the consent of the Parties involved in the dispute, or (iii) by operation
of law.
