government  restrictions  to remit  royalties  from any country in the  LICENSED

paragraph,  when billed out, except that upon any termination of this Agreement,
all  shipments  made on or  prior  thereto  shall  be  considered  as sold  (and
therefore subject to royalty).  Royalties paid on sales of ROYALTY-BASE PRODUCTS

                                  ARTICLE XIII

                                     GENERAL

         13.01 This  Agreement  shall not be transferred or assigned by LICENSEE
to any party  other than to a  successor  or  assignee  of the  entire  business
interest of LICENSEE without the approval of LICENSOR'S REPRESENTATIVE.

         13.02 This  Agreement  does not confer any  immunity  from or  defenses
under the antitrust laws, the laws and regulations pertaining to or administered
by the Food and  Drug  Administration,  or the  export  laws nor does it  confer
immunity from a charge of patent misuse. Furthermore,  LICENSEE'S, AFFILIATE(S),
or sublicensee's  acquisition and exercise of rights hereunder are not immunized
from the  operation  of any state or Federal  law by reason of the source of the
grant.  This  Agreement  does not  constitute an  endorsement by LICENSOR of any
ROYALTY-BASE  PRODUCTS and LICENSEE  shall not state or imply in any medium that
such endorsement exists as the result of this Agreement.

         13.03  LICENSOR  makes  no  warranty,   express  or  implied,   or  any
representations  regarding the patentability,  validity or scope of the LICENSED
PATENT  APPLICATION or that LICENSED PATENT APPLICATION may be exploited without
infringing patents of third parties.

         13.04  LICENSEE,   its  AFFILIATE(S)   and   sublicensees   agree  that
ROYALTY-BASE PRODUCTS will be manufactured substantially in the United States in
compliance with 35 United States Code 209(b).

         13.05 The decision of  LICENSOR'S  REPRESENTATIVE  on any  requirement,
dispute, interpretation, modification, or termination of this Agreement shall be
reduced to writing and a copy mailed or otherwise  furnished  to LICENSEE.  Such
decision shall be final,  provided that LICENSEE may, within thirty (30) days of
receiving  notice of such decision,  submit a written appeal through  LICENSOR'S
REPRESENTATIVE  and the  Intellectual  Property Counsel of the Army to the Judge
Advocate  General,  Department of the Army,  Washington,  DC  20310-2207,  which
appeal  shall set forth in detail the decision  being  appealed and the basis of
the appeal and may include appropriate  supporting materials.  Implementation of
such decision shall be stayed pending a final resolution of such appeal. Pending
such final resolution, LICENSEE shall proceed diligently with the performance of
its obligations under this Agreement.

         13.06 Except as expressly  provided herein, the parties agree that, for
the term of this  Agreement  and for five (5) years  thereafter,  the  receiving
party shall keep  completely  confidential  and shall not  publish or  otherwise
disclose and shall not use for any purpose except for the purposes  contemplated
by this Agreement any CONFIDENTIAL INFORMATION furnished to it by the disclosing
party hereto  pursuant to this  Agreement,  except that it can be established by
the receiving party by competent proof that such CONFIDENTIAL INFORMATION:



                                      -11-






                    i. was  already  known to the  receiving  party,  other than
under an obligation of confidentiality, at the time of disclosure;

                    ii. was generally  available to the public or otherwise part
of the public domain at the time of its disclosure to the receiving party;

                    iii. became  generally  available to the public or otherwise
part of the public domain after its disclosure and other than through any act or
omission of the receiving party in breach of this Agreement; or

                    iv. was  subsequently  lawfully  disclosed to the  receiving
party by a person other than a party hereto.

         13.07  LICENSEE  may use or  disclose  information  disclosed  to it by
LICENSOR to the extent such  disclosure  is  reasonably  necessary  in filing or
prosecuting patent applications,  prosecuting or defending litigation, complying
with applicable governmental  regulations or otherwise submitting information to
tax or governmental authorities, conducting clinical trials, acquiring potential
investors who are bona fide  investment  banks and/or venture  capital firms, or
making a permitted  sublicense  or otherwise  exercising  its rights  hereunder,
provided that if LICENSEE is required to make any such  disclosure of LICENSOR'S
CONFIDENTIAL INFORMATION, other than pursuant to a confidentiality agreement, it
will give  reasonable  notice to LICENSOR of such  disclosure  and,  save to the
extent  inappropriate  in the  case of  patent  applications,  will use its best
efforts  to  secure  confidential  treatment  of such  information  prior to its
disclosure (whether through protective orders or otherwise).  LICENSEE agrees to
keep records of  confidentiality  agreements between itself and third parties in
accordance  with the treatment of CONFIDENTIAL  INFORMATION  given in ARTICLE V,
paragraph 5.01, above.

         13.08 The  parties  shall  notify  each  other of any  changes in name,

applied by the Federal  courts in the  District of  Columbia,  United  States of

other than those expressly stated herein or as may be subsequently  agreed to by
the parties hereto in writing.

         13.11 All prior reviews and approvals  required by  regulations  or law
have been obtained by the Command prior to the execution of this Agreement.  The
Command official executing this Agreement has the requisite  authority to do so.
Notwithstanding  the  delegation  of authority to execute this  Agreement to the
individual  designated,  the Secretary of the Army has reserved to the Assistant
Secretary of the Army (Research,  Development and  Acquisition)  the opportunity
provided  by 15 U.S.C.  Section  3710a(c)(5)(A),  to  disapprove  or require the
modification of this Agreement within 30 days of the date it is presented to him
or her by the Command.

         13.12 Failure of any party to enforce any term, covenant,  or condition
herein contained shall not be deemed to be a waiver of such term,  covenant,  or
condition herein contained.

         13.13  Neither  party  shall be in default  hereunder  by reason of its
delay in the  performance  of, or failure  to  perform,  any of its  obligations
hereunder,  other than  LICENSEE'S  obligations  to make payments to LICENSOR in
accordance with the terms of this Agreement, if such delay is caused by strikes,
acts of God or the public  enemy,  riots,  or without the fault or negligence of
the other party.  During the  pendency of such  intervening  event,  each of the
parties  shall  take all  reasonable  steps to  furnish  the  services  required
hereunder by other means,  and, in any event,  shall,  upon  termination of such
intervening event, forthwith resume obligations under this Agreement.
