Services in any country, and Licensee provides Caltech with reasonably
satisfactory evidence for such requirement, such third-party payments shall be
fully creditable against royalties owed to Caltech hereunder, provided that in
no one year shall such expenses be

                                       8
<PAGE>

credited against more than twenty-five percent (25%) of royalty payments to

with respect to all or any part of Licensed Products and Caltech so notifies
Licensee in writing, and Caltech introduces to Licensee a third party which it
requests Licensee to Sublicense a specific application for development, then
Caltech and Licensee shall negotiate in good faith as to whether a commercially
reasonable Sublicense can be negotiated with such third party. If the parties do
not reach agreement within ninety (90) days, any additional efforts shall be
determined in accordance with Article 12. If Licensee then fails to make any
required efforts, and does not remedy that failure within sixty (60) days after
further written notice to Licensee, Caltech may convert the license granted in
Paragraph 2.1 to a nonexclusive license as to the specific application as to
which Licensee is, pursuant to Article 12, not deemed to be in compliance with
Para. 5.1, and the royalties payable under this Agreement shall be reduced by
fifty percent (50%) for Licensed Products sold under such a nonexclusive
license.

notice, either (a) cause the infringement to terminate or (b) initiate a legal
action against the infringer, Licensee may, upon notice to Caltech, initiate an
action against the infringer at Licensee's expense, either in Licensee's name or
in Caltech's name if so required by law.

         6.3 If a declaratory judgment action alleging invalidity,
unenforceability or infringement of any of the Licensed Patent Rights is brought
against Licensee and/or Caltech, Caltech shall defend same in accordance with
Section 6.1. Licensee shall have sole control of the action if Licensee agrees
to bear all the costs of the action subject to Article 6.8.

         6.4 In the event one party shall carry on a legal action pursuant to
Paragraphs 6.1, 6.2 or 6.3, the other party shall fully cooperate with and

attorneys' fees) incurred by either party and then to the payment to Caltech of
any royalties against which were credited expenses of the action in accordance
with Paragraph 6.4. Any remainder shall be divided between the parties as
follows:.

                  (a) To the extent the amount recovered reflects lost profits
         of Licensee, Licensee shall retain the remainder, less the amount of
         any royalties that would have been due Caltech on sales of Licensed
         Product lost by Licensee as a result of the infringement had Licensee
         made such sales, provided that Licensee shall in any event retain at
         least seventy percent (70%) of the remainder; and

         such amount shall in no event exceed thirty percent (30%) of the
         remainder; or

                  (c) to the extent the amount recovered does not reflect lost
         profits, seventy percent (70%) shall be paid to the party initiating
         the action and thirty percent (30%) to the other party.

         6.7 If an infringement or infringements by third parties of Licensed
Patent Rights is on a scale that significantly affects sates of Licensed
Products, and neither Caltech nor Licensee elect to bring an infringement suit
against the infringers, the royalties hereunder payable by Licensee pursuant to
Article III shall be reduced by twenty-five percent (25%) of the sums otherwise
payable if Licensee presents information to Caltech that such infringer has
refused to enter into a royalty-bearing, Sublicensing agreement with Licensee on
terms reasonably acceptable to Licensee.

         6.8 The allowed reductions set forth in Paragraphs 6.4 and 6.7 shall

Subject: Caltech / OmniCorder Option Agreement and License Agreement

Dear Mark,

As we discussed today on your cell phone, this letter will serve to modify the
existing OmniCorder / Caltech Option Agreement of August 27, 1998 (Effective
Date) to extend the Option Period from nine (9) months to ten (10) months from
the Effective Date. This extension will be for no additional consideration and
will allow more time for both of us to review the additional provisional US
patent applications for "QWIP" related JPL technology.

I will update EXHIBIT A of the attached License Agreement after we have a review
by our patent attorney and a decision on which of the pending provisional
applications, if any, will be filed as non-provisional CIP applications to the
parent CIT 2426(08/708,076) application.

You indicated that you would have a revised form of the License Agreement sent
for our review. From our previous discussions and your letter of April 23, 1998,
I expect that we will find your proposed revisions acceptable. If so, we will
return two originals of the updated License Agreement to you so that you may
exercise your option and acquire the license, should you choose to do so.

                                                       Sincerely,
