sold any  Biken  Combined  Product(s)  to any  party  in or  outside  the  Biken
Non-Exclusive   Licensed   Territory  for  export  or  sale  outside  the  Biken
Non-Exclusive Licensed Territory, without Hemispherx's prior written consent.

8.       Patents
         8.1 Hemispherx  agrees to maintain  faithfully the licensed  patents in
the Biken  Non-Exclusive  Licensed  Territory as reflected in Exhibits A and pay
all taxes, annuities,  maintenance fees and the like to ensure that the licensed
patents are legally maintained.

         8.2 Biken shall promptly notify  Hemispherx of any  infringement of the
Hemispherx Licensed Patents,  within the Biken Non-Exclusive Licensed Territory,
misappropriation of a trade secret or declaration of an interference  proceeding
relating to the Hemispherx  Licensed Patents or Hemispherx Licensed Know-How and
shall provide Hemispherx with all available evidence relating thereto.

              8.2.1 Biken and  Hemispherx  will  immediately  consult  with each
                    other as to the best manner to proceed.
              8.2.2 Hemispherx shall have the right, but not the obligation,  to
                    bring,  defend and maintain any appropriate  suit or action.
                    If Hemispherx  requests Biken to join in such suit or action
                    and Biken  agrees to do so,  Biken shall  execute all papers
                    and perform such acts as may be reasonably required and may,
                    at its  option be  represented  by  counsel  of its  choice.
                    Hemispherx and Biken shall each be responsible for their own
                    expenses  (including legal fees) in connection with any such
                    suit or action. Should Hemispherx lack standing to bring any
                    such action,  then  Hemispherx may cause Biken to do so upon
                    first  undertaking  to indemnify and hold Biken harmless (to
                    the extent permissible by law) from all consequent liability
                    and promptly to reimburse all reasonable expenses (including
                    legal fees) stemming therefrom.
              8.2.3 If  Hemispherx  fails to take  action  with  respect to such
                    matters within a reasonable  period,  but in any event,  not
                    more  than one  hundred  and  twenty  (120)  days  following
                    receipt of such  notice and  evidence,  Biken shall have the
                    right, but not the obligation, to bring, defend and maintain
                    any appropriate suit or action.  If Biken finds it necessary
                    to join Hemispherx in such suit or actions, Hemispherx shall
                    execute  all  papers  and  perform   such  acts  as  may  be
                    reasonably  required and may, at its option,  be represented
                    by counsel of its  choice.  Biken shall pay  Hemispherx  the
                    reasonable expenses of Hemispherx (including its legal fees)
                    in connection with any such suit or action.
              8.2.4 In the  absence  of any  agreement  between  the  parties to
                    jointly  bring any  action or suit  hereunder  and share the
                    expenses thereof, any amount recovered in any such action or
                    suit shall be  retained by the party  bearing  the  expenses
                    thereof.





9.       Improvements
         9.1 Any  improvement or technical  advances made in or grant of further
Letter  Patent in  respect of the  Hemispherx  Licensed  Patents  or  Hemispherx
Licensed  Know-How by Hemispherx shall forthwith be disclosed to Biken,  whether
the subject of Letter Patent or not. For the avoidance of doubt, this disclosure
shall not  constitute  the grant of a license to use or exploit such improved or
advanced patents or know-how or to manufacture, use or sell improved or advanced
Combined Product(s).

10.      Force Majeure
         10.1 "Force  Majeure"  shall be  deemed  to have  prevented,

obligations  hereunder if such event occurs by reason of flood, fire, explosion,
strike,  war,  revolution,  civic  commotions,  political  riot,  acts of public
enemies,  blockade  or  embargo  or  sanctions  or  any  law,  interdict,  order
proclamation,  regulation,  ordinance, demand or requirements of any government.
Where the  party so  affected  shall be  excused  from  such of its  obligations
hereunder as it is unable to perform to the extent of Force Majeure, it shall be
excused for so long as such prevention, restriction or interference shall remain
in force plus a reasonable  period  thereafter.  Notwithstanding  the foregoing,
should Force Majeure  continue for an unbroken period of twelve (12) months then
either  party  shall be  entitled  to  terminate  this  Collaboration  Agreement
forthwith by giving written notice to the other.
         10.2 Neither  party  shall be held  responsible  for damages
caused by any delay or default due to force majeure.

                        judgment has come to its notice;
               then and in such event, the non-defaulting  party, at its option,
may with  immediate  effect  terminate its  obligations to and the rights of the
defaulting party under the license granted in this  Collaboration  Agreement and
cancel this Collaboration Agreement by written notice to the defaulting party.
         12.4  In  the  event  of  the   cancellation  or  termination  of  this

collaboration with the Co-Researcher, by using the Prototype Vaccine Preparation
as defined in Paragraph (6) of Article 2 hereof (hereinafter  referred to as the
"Evaluation"),  in  order  to  select  candidates  of  both  viral-antigens  and
adjuvant-auxiliaries  which are identified as the most promising  substances and
determine the  formulations  of potential  influenza  virus  vaccine  candidates
containing   such   viral-antigens   as  the   active   ingredients   and   such
adjuvant-auxiliaries,  during and in the course of the Research Project aimed at
practical use of a newly developed  adjuvanted-influenza  virus vaccine which is
