         Maryland or a designee of that office  within one year after the injury
         to the person or property that is the basis of the claim.

         liability  and  property  damage  insurance  coverage  for itself,  its
         officers,  employees and agents,  in the following  minimum amounts per
         policy period:

               (a)  Comprehensive  liability:  (bodily  injury and loss of life)
                    $1,000,000 per claim; $2,000,000 aggregate;
               (b)  Property damage: $50,000 per claim; $2,000,000 aggregate.

         contractually  assumed  liabilities  referred to in Section  11.3,  and
         agrees to maintain such coverage throughout the term of this Agreement.
         A certificate  evidencing required insurance coverage will be delivered
         to UM at or before  execution of this Agreement.  Sponsor also warrants
         that its comprehensive  liability insurance is an occurrence policy, or

         insurance.

11.3     Sponsor will defend,  indemnify,  and hold harmless UM, the  University
         System of Maryland, and the State of Maryland,  and regents,  officers,
         employees,  students,  and agents of UM (each individually a "UM Party"
         and all, collectively,  "UM Parties") against any and all claims, costs
         or liabilities, including attorney's fees and court costs at both trial
         and appellate levels, for any loss, damage, personal injury, or loss of
         life,  (a) caused by the actions of Sponsor or its officers,  servants,
         or agents, or third parties acting on behalf of or under  authorization
         from Sponsor in the performance of this  Agreement;  (b) arising out of
         use by Sponsor,  its  officers,  servants,  or agents,  or by any third
         party  acting on  behalf  of or under  authorization  from  Sponsor  of
         products,   processes,  or  protocols  (including  licensed  University
         Intellectual  Property or Joint  Intellectual  Property)  developed  by
         Sponsor, its officers,  servants, or agents, or by third parties acting
         on behalf of or under authorization from Sponsor; or (c) arising out of
         use, by UM or its  employees or students,  of products,  processes,  or
         protocols developed by Sponsor, its officers,  servants,  or agents, or
         by third  parties  acting  on  behalf  of or under  authorization  from
         Sponsor. Sponsor's agreement to defend, indemnify and hold harmless the

         writing  after UM  receives  notice  of any  claim,  and (b) UM and any
         involved UM Party fully  cooperating with Sponsor in the defense of any
         such claim. Sponsor's agreement to defend,  indemnify and hold harmless
         the UM  Parties  will  not  apply  to any  claim,  cost,  or  liability
         attributable solely to

                                     Page 5

         the negligence or willful misconduct of an UM Party.

         interpreted  as: (a) a denial to either  party of any remedy or defense
         available  to it under  the  laws of the  State  of  Maryland;  (b) the
         consent of the State of Maryland or its agents and agencies to be sued;
         or  (c) a  waiver  of  sovereign  immunity  or any  other  governmental
         immunity of the State of  Maryland  and the UM beyond the extent of any
         waiver provided by law.

         after the date of receipt of Confidential Information,  disclose or use
         the Confidential Information.
          (b)(1) These obligations of non-disclosure  and nonuse do not apply to
          any   Confidential   Information,   which  the  receiving   party  can
          demonstrate by reliable written evidence:
               (i)  was  generally  available  to  the  public  at the  time  of
                    disclosure to the receiving party; or
               (ii) was already in the possession of the receiving  party at the
                    time  of  the   disclosure,   other  than   pursuant   to  a
                    confidential  disclosure  agreement  between the parties and
                    not due to any  unauthorized  act by the receiving party; or
               (iii)was   developed  by  the   receiving   party  prior  to  the
                    disclosure;  or
               (iv) the receiving  party is required by law to disclose.
          (b)(2)  These  obligations  of  non-disclosure  and  nonuse  will  not
          continue to apply to any Confidential Information, which the receiving
          party can demonstrate by reliable written evidence:

               (i)  has become  generally  available  to the  public  other than
                    through a breach of this  Agreement by the  receiving  party
                    after disclosure;
               (ii) has   been   acquired   by   the   receiving   party   on  a
                    nonconfidential  basis from any third party  having a lawful
                    right  to  disclose  it to the  receiving  party;  or
               (iii)corresponds to information  developed by the receiving party
                    independent  of and with no  reliance  upon  the  disclosing
                    party's  Confidential  Information.
          (c)  Each  party  will use that  level of care to  prevent  the use or
          disclosure  of  the  other  party's  Confidential  Information  as  it
          exercises in protecting its own Confidential Information.
          (d)  All   Confidential   Information   will  be  clearly   marked  as
          confidential by the disclosing party and if not in written or tangible
          form  when   disclosed,   will  be  so  indicated  on   disclosure  as
          confidential   and  then  summarized  in  writing  and  so  marked  as
          confidential within 30 days after disclosure to the receiving party.
          (e)  Notwithstanding  the foregoing,  Sponsor is permitted to disclose
          and  use  the  Confidential   Information  to  the  extent  reasonably
          necessary to enable  Sponsor to exercise its option under this License
          Agreement, provided that any disclosure is made subject to

                                     Page 6


          confidentiality restrictions consistent with those accepted by Sponsor
          in this  Agreement.
          (f) Sponsor  recognizes  that UM is an  educational  institution  with
          standards  and practices for  protection of  Confidential  Information
          which differ from Sponsor's standards and practices. By this Agreement
          UM undertakes to use reasonable efforts to protect the confidentiality
          of Sponsor's Confidential  Information.  Sponsor agrees that, provided
          such  efforts  are made,  it will not seek to hold UM or UM  Personnel
          liable  in  the  event  of   disclosure   of  Sponsor's   Confidential
          Information.
          (g)  Sponsor  recognizes  that the  records  of UM are  subject to the
          Maryland  Access to  Public  Records  Law.  Sponsor  asserts  that any
          Confidential Information of Sponsor is confidential,  proprietary, and
          trade secret  information,  not subject to disclosure under Maryland's
          Access to Public  Records  Law. UM agrees to assert  this  position in
          response to any request for public information applicable to Sponsor's
          Confidential  Information  or annual  sales  reports,  and to promptly
          notify   Sponsor  upon  receipt  of  requests  for  its   Confidential
          Information. The Maryland Access to Public Records Law is at Title 10,
          Subtitle 6, Part III,  State  Government  Article,  Annotated  Code of
          Maryland.
          (h) Upon  termination of this  Agreement for any reason,  Sponsor will
          return to UM all material  provided to Sponsor  which is  Confidential
          Information, together with all copies and other forms of reproduction,
          except  that a  single  archive  copy may be kept in  Sponsor's  legal
          files.  Each party agrees that  termination of this Agreement does not
          alter the 5 year  obligation of  confidentiality  set forth in Section
          12.1(a).
