                              FIRST AMENDMENT TO
                        RESEARCH AND LICENSE AGREEMENT


     THIS FIRST AMENDMENT TO RESEARCH AND LICENSE AGREEMENT (the "Amendment") is
made this 1st day of September, 1995, by and among SRI International, a
California nonprofit public benefit corporation ("SRI"), the David Sarnoff
Research Center (a wholly owned subsidiary of SRI), a Delaware corporation
("Sarnoff") and SolarCare Technologies Corporation, a Delaware corporation
("STC").

                             W I T N E S S E T H:

     WHEREAS,  SRI, Sarnoff and STC entered into that certain Research and
License Agreement dated April 26, 1995 (the "Agreement", initially capitalized
terms being used herein as defined therein, unless otherwise defined herein);
and

     WHEREAS, SRI, Sarnoff and STC desire to amend the Agreement, as provided
herein.

     NOW, THEREFORE, SRI, Sarnoff and STC, each intending to be legally bound
hereby, covenant and agree as follows:

     Section 1.  Amendments to Agreement.
                 -----------------------

          Sections 3.1 through 3.7 of the Agreement, effective as of the date
hereof, are hereby amended by deleting such Sections in their entirety and
substituting the following therefor:

          3.1  Conduct of Research.  During the Development Period each of
               -------------------
Sarnoff and SRI shall use their commercially reasonable efforts to conduct the
Development Program in accordance with the tasks set forth on Exhibit A (each, a
"Task" and, collectively, the "Tasks"), as such Exhibit may be amended, in
writing, from time to time by Task Orders (as such term is hereinafter defined).
Each Task shall describe in reasonably sufficient detail (a) the research
activities to be conducted and the objectives thereof, (b) the responsibilities
of the parties, the principal researchers (if any) and any specific resources
required to conduct the research activities, (c) the total funding and the
payment schedule therefor and (d) an estimated schedule for such activities.
Sarnoff and SRI shall conduct the Development Program in good scientific manner,
and in compliance in all material respects with all requirements of applicable
laws, rules
<PAGE>

and regulations. Because the research services to be performed are of an
advisory or experimental nature, Sarnoff and SRI do not warrant that the
Development Program, in whole or in part, will be successful or achieve the
objectives set forth on Exhibit A.

          3.1.1.  The Development Program to be performed by Licensors for STC
shall be administered by a Program Advisory Team (the "Program Advisory Team").
The Program Advisory Team shall consist of three members, with one person
representing each of SRI, Sarnoff and STC.  The Program Advisory Team shall
communicate, confer and/or meet from time to time at the request of any party.
The initial members of the Program Advisory Team shall be as follows:


     Person              Affiliation    Telephone         Facsimile
     ------              -----------    ---------         ---------

     Sam Niedbala        STC            (610) 822-1820    (610) 882-1830
     Howard Rivenburg    Sarnoff        (609) 734-        (609) 734-2323
     Luke Schneider      SRI            (415) 859-5051    (415) 859-2813


The members of the Program Advisory Term may be replaced, subject to the prior
approval of STC, which approval shall not be withheld unreasonably.  The role of
the Program Advisory Team shall be to facilitate communication among SRI,
Sarnoff and STC with respect to the conduct of the Development Program and to
plan for and administer Task Orders to maximize the opportunity for the
successful completion of Task Orders in the most efficient and cost effective
manner.  Specifically, the role of the Program Advisory Team shall include, but
shall not be limited to the following:  (i) identifying to STC areas of
necessary or desirable research for Task Orders (including the development of
Task Orders for the second year effort, as set forth in Section 3.3); (ii)
advising STC with respect to Task Order priorities; (iii) advising STC with
respect to the objectives, scope, methodology and specifications of each Task
Order; (iv) maximizing the opportunity for successful completion of Task Orders
by identifying the most appropriate personnel to implement a particular Task
Order and (v) overseeing the conduct and completion of each Task Order.
Notwithstanding the foregoing, the recommendations of the Program Advisory Team
shall be advisory only and STC shall specify which new Tasks to pursue and in
which order, the objectives, scope, methodology and specifications of each Task
Order, the selection of the personnel (and institution) to implement each Task
Order and the form, scope and manner of communicating and/or delivering the
interim and final results of each Task Order.  Except as set forth in Section
3.6, neither SRI nor Sarnoff shall charge or receive any compensation for the
administration of the Development Program.  On the basis of the foregoing, from
time to time during the term of the Development Period, (y) STC and Sarnoff may
mutually agree on the scope of new Tasks to be conducted by Sarnoff to be
included in the Development Program and/or (z) STC and SRI may mutually agree on
the scope of new Tasks to be conducted by SRI to be included in the Development
Program.

          3.1.2.  Each new Task shall be in writing ("Task Order") and shall
reference the Agreement and describe in reasonably sufficient detail (a) the
research activities to

                                      -2-
<PAGE>

be conducted and the objectives thereof, (b) the responsibilities of the
parties, the principal researchers (if any) and any specific resources required
to conduct the research activities, (c) the total funding and the payment
schedule therefor and (d) an estimated schedule for such activities.

          3.1.3.  STC and SRI or Sarnoff, as the case may be, shall execute a
copy of each mutually acceptable Task Order which thereafter shall be
incorporated in and made a part of this Agreement.

          3.1.4.  Upon receipt by Sarnoff or SRI, as the case may be, of a
fully-executed copy of the Task Order and any initial research payment required
for such Task, Sarnoff and/or SRI shall initiate each new Task under the
Development Program.

          3.1.5.  Licensors shall ensure that all of their respective employees
and independent contractors have executed and delivered binding agreements
agreeing to assign all intellectual property rights to Sarnoff or SRI, as the
case may be, and to promptly report the conception and reduction to practice of
all discoveries and inventions to the Sarnoff or SRI Intellectual Property
Office, as the case may be.

     3.2. Funding.  In consideration of the participation of Sarnoff and
          -------
SRI in the Development Program, STC agrees to pay to Sarnoff, on behalf of
Licensors, a research fee of ***************************($*********) for the
work to be performed during the first year of this Agreement (the "Year 1 Fee").
The Year 1 Fee shall be paid to Sarnoff, as set forth below.  Licensors shall
not incur expenses in conducting the Development Program in excess of such total
amount, and STC shall have no obligation to reimburse Licensors for expenses
incurred in excess of such total amount, unless otherwise expressly agreed to in
writing by both parties.  If it appears to Licensors that the Development
Program to be conducted during the first year of this Agreement cannot be
completed without incurring expenses in excess of such total amount, Licensors
shall notify STC, and STC shall determine whether (a) to discontinue the
Development Program when such total amount has been spent, (b) to authorize
Licensors to spend additional amounts, or (c) to revise the scope of the
Development Program, as appropriate.  Such Year 1 Fees are non-refundable and
non-creditable against future royalties, and following an initial payment by STC
to Sarnoff of **************************** ($*******), within * days of the
Effective Date, Sarnoff and SRI shall initiate work on the Development Program.
Such initial payment shall be applied to the Tasks in accordance with Exhibit A
and subsequent Task Orders.  Thereafter, all future payments by STC will be
based on the Task Order schedule for payment terms as called for under Section
3.1.2 (c) above.

     3.3. Second Year Funding.  Not less than ***** (**) days prior to the
          -------------------
expiration of the first year of the Development Period, the Program Advisory
Team shall have developed and presented a written development proposal in the
form of proposed Task Orders, for the second year effort.  STC shall commit to a
research fee of ****************************** ($*******) for the work to be
performed during the second year (the "Year 2 Fee") to maintain the license
granted herein, except in the event that the Development Program is terminated
or

                                      -3-
<PAGE>

modified by STC pursuant to Sections 13.3 and 13.6 or the second following
sentence. The Year 2 Fee shall be paid in accordance with the last sentence of
this Section 3.3. Notwithstanding the commitment of the Year 2 Fee and, in
addition to the rights of STC set forth in the second sentence of this Section
3.3, STC may request that the Year 2 Fee be reduced to an amount less than
$******* in the event that Sarnoff and SRI have failed to substantially perform
the Development Program during the first year of the Development Program. In
such case, a new Development Program for the second year may be entered into by
written consent of the Parties. The Year 2 Fee is non-refundable and non-
creditable against future royalties. The payment by STC of the Year 2 Fee will
be in accordance with the terms of the Task Orders for the second year of the
Development Program.

          3.4.  Renewal.  By mutual written agreement and consent of the
                -------
Parties, the Development Program may be extended beyond the Development Period
for additional periods of one (1) year each.  If STC desires to renew the
Development Program, STC shall give the Program Advisory Team written notice of
such election not less than sixty (60) days prior to the expiration of the then
current Development Period, as applicable.  The Program Advisory Team, on behalf
of Licensors, shall have thirty (30) days to present to STC a written
development proposal in the form of proposed Task Orders for the renewal year.

          3.5.  Records.  SRI and Sarnoff shall each maintain records, in
                -------
sufficient detail and in good scientific manner, which shall reflect all work
done and results achieved in the performance of each of their respective Tasks
included in the Development Program (including all data in the form required
under all applicable laws and regulations).

          3.6.  Meetings and Progress Reports.  During the term of the
                -----------------------------
Development Program, Sarnoff and SRI shall each keep STC generally informed of
the progress under each of their respective Tasks, including telephonic
conferences or other communications at STC's request and meetings at Sarnoff,
SRI or STC, at STC's request.  The Program Advisory Team will meet approximately
four times a year, but in no case shall there be (i) more than four (4) months
between meetings or a delay of more than one (1) month from the date of
completion of a Task, except as mutually agreed in writing.  The first meeting
shall be held at Sarnoff shortly after the Effective Date.  The reasonable
travel and subsistence costs for those SRI and/or Sarnoff meeting participants
invited by STC to attend a meeting will be invoiced separately from Development
Program payments and shall be paid by STC, upon the presentation of accurate and
complete conforming documentation.  If requested by STC, Sarnoff or SRI, as the
case may be, will provide STC with minutes of each meeting within ten (10) days
after the conduct of such meeting.  STC shall give GIB (as such term is defined
in Section 17.5) prompt notice of the arrangement of any proposed meeting
between STC and any Licensor relating to the Development Program.  A
representative of GIB (reasonably acceptable to the parties) shall be permitted
to attend any such meeting.  All costs and expenses of GIB and its
representative in connection with attendance at such meeting shall be borne by
GIB.  In the event and to the extent required by STC and included in a Task
Order, a written report from Sarnoff and SRI containing, in reasonable detail, a
description of the work performed by Sarnoff and SRI under each of their

                                      -4-
<PAGE>

respective Tasks of the Development Program and the results thereof will be
transmitted to STC upon the first to occur of (i) fifteen (15) days after the
completion of each Task and (ii) five (5) days prior to each scheduled meeting
relating to such Task.

          3.7.  Final Task Report.  In the event and to the extent required by
                -----------------
STC and included in a Task Order, within thirty (30) days following the
completion of each of their respective Tasks, Sarnoff and/or SRI, as the case
may be, shall prepare and provide STC with a detailed written final Task report,
which shall describe the work performed by Licensors under each of their
respective Tasks of the Development Program and the results thereof.

     Section 2.  Further Action and Assurances.
                 -----------------------------

          STC, SRI and Sarnoff hereby agree to execute and deliver such
additional documents and shall cause such further and additional action to be
