responsibility, and the other party shall have the right, at its own expense, to
file, prosecute, and maintain such patent application or patent.

               (b) The Steering  Committee  shall determine which party shall be
responsible for the filing,  prosecution and maintenance of patent  applications
and patents  within the Joint  Patent  Rights on a case by case basis,  with the
understanding  that  it  is  the  parties'  intent  that  GENEMEDICINE  will  be
responsible for the filing,  prosecution and maintenance of patent  applications
and patents  within the Joint Patent  Rights  related to gene  delivery and gene
expression  and BIOJECT  will be  responsible  for the filing,  prosecution  and
maintenance  of patent  applications  and patents within the Joint Patent Rights
related  to  NFIDs.  In the  event  that a party  responsible  for  the  filing,
prosecution and maintenance of any patent application or patent within the Joint
Patent Rights desires to abandon such patent  application or patent,  or if such
party later declines  responsibility for such patent application or patent, such
party shall provide  reasonable  prior written  notice to the other party of its
intention to abandon or decline  responsibility,  and the other party shall have
the right, but not the obligation, to prepare, file, prosecute, and maintain any
such patent  application or patent within the Joint Patent  Rights.  The parties
shall share equally the costs of filing,  prosecuting and maintaining patents or
patent applications within the Joint Patent Rights.

          7.3  Cooperation of the Parties.  Each party agrees to cooperate fully
in the  preparation,  filing,  and  prosecution  of any Patent Rights under this
Agreement. Such cooperation includes, but is not limited to:

               (a)  executing  all  papers and  instruments,  or  requiring  its
employees or agents, to execute such papers and instruments, so as to effectuate
the  ownership of Patent Rights set forth in Section 7.1 and to enable the other
party to apply for and to prosecute patent applications in any country; and

               (b) promptly  informing the other party of any matters  coming to
such party's  attention that may affect the preparation,  filing, or prosecution
of any such patent applications.





         7.4      Enforcement Rights.

               (a) Infringement of Third Party Rights.  GENEMEDICINE and BIOJECT
shall  promptly  notify the other in writing of any  allegation by a Third Party
that the activity of either of the parties in connection with the  Collaborative
Alliance  infringes  or may infringe the  intellectual  property  rights of such
Third  Party.  GENEMEDICINE  shall have the right to control  the defense of any
claims with  respect to the  GENEMEDICINE  Technology  at its own expense and by
counsel of its own choice.  BIOJECT  shall have the right to control the defense
of any claims with respect to the BIOJECT  Technology  at its own expense and by
counsel of its own choice.  In the event that such matter  includes  claims with
respect to the Joint Patent Rights,  the party  responsible  for prosecution and
maintenance  of the  applicable  Joint Patent Rights under Section  7.2(b) shall
have the right to  control  the  defense  of such  claims by  counsel of its own
choice and the parties  shall share equally the costs with respect  thereto.  If
either party fails to proceed in a timely  fashion with regard to the defense of
any claims with  respect to the  Contributed  Technology,  the other party shall
have the right to control any such  defense of such claim at its own expense and
by counsel of its own choice,  and such party  shall have the right,  at its own
expense,  to be  represented  in any such  action by counsel of its own  choice.
Neither party shall have the right to settle any patent infringement  litigation
under this Section 7.4(a) in a manner that diminishes the rights or interests of
the other  party or  obligates  the other  party to make any payment or take any
action without the consent of such other party.

               (b) Infringement by Third Parties. GENEMEDICINE and BIOJECT shall
promptly  notify the other in writing of any alleged or threatened  infringement
of any patent  included in the  GENEMEDICINE  Patent Rights,  the BIOJECT Patent
Rights or the Joint Patent Rights of which they become aware. GENEMEDICINE shall
have the right to institute, prosecute and control any action or proceeding with
respect to infringement of any patent included in the GENEMEDICINE Patent Rights
at its own  expense  and by counsel of its own  choice.  BIOJECT  shall have the
right to institute,  prosecute and control any action or proceeding with respect
to  infringement  of any patent included in the BIOJECT Patent Rights at its own
expense  and by counsel of its own choice.  In the event any patent  included in
the Joint Patent Rights is infringed by a Third Party, the party responsible for
prosecution and maintenance of the applicable  Joint Patent Rights under Section
7.2(b) shall have the right to  institute,  prosecute  and control any action or
proceeding  with respect to such patent,  and the parties shall share equally in
the expenses thereof. With respect to infringement of any patent included in the
Patent  Rights  of  either  party,  if such  party  fails to bring an  action or
proceeding  within (a) 60 days following the notice of alleged  infringement  or
(b) 10 days before the time limit, if any, set forth in the appropriate laws and
regulations  for the filing of such actions,  whichever  comes first,  the other
party  shall  have the right to bring  and  control  any such  action at its own
expense and by counsel of its own  choice,  and such party shall have the right,
at its own expense,  to be  represented in any such action by counsel of its own
choice.  In the event a party  brings an  infringement  action,  the other party
shall  cooperate  fully,  including  if  required  to  bring  such  action,  the
furnishing of a power of attorney.  Neither party shall have the right to settle
any patent  infringement  litigation  under this Section 7.4(b) in a manner that
diminishes  the rights or  interests  of the other party  without the consent of
such other party. Except as otherwise agreed to by the parties as part of a cost
sharing arrangement, any recovery realized as a result of such litigation, after
reimbursement  of any litigation  expenses of  GENEMEDICINE  and BIOJECT,  shall
belong to the party who brought the action.





                                    ARTICLE 8
                          CONFIDENTIALITY; PUBLICATIONS

          8.1  Nondisclosure.  During  the Term and for a period of three  years
thereafter,  each party shall maintain all Confidential Information of the other
party as confidential and shall not disclose any such  Confidential  Information
to any Third Party or use any such  Confidential  Information  for any  purpose,
except (a) as expressly  authorized by this  Agreement,  (b) as required by law,
rule,  regulation or court order  (provided that the disclosing  party shall use
commercially  reasonable  efforts to obtain  confidential  treatment of any such
information  required to be  disclosed),  or (c) to its  Affiliates,  employees,
agents, consultants and other representatives to accomplish the purposes of this
Agreement, so long as such persons are under an obligation of confidentiality no
less  stringent than as set forth herein.  Each party may use such  Confidential
Information  only to the extent  required  to  accomplish  the  purposes of this
Agreement. Each party shall use at least the same standard of care as it uses to
protect  its  own  Confidential  Information  to  ensure  that  its  Affiliates,
employees, agents, consultants and other representatives do not disclose or make
any unauthorized use of the other party's Confidential  Information.  Each party
will promptly notify the other party upon discovery of any  unauthorized  use or
disclosure of the other party's Confidential Information.

          8.2 Publications. Each party recognizes that the publication of papers
regarding results of the research and development  activities performed pursuant
to the Collaborative Alliance,  including oral presentations and abstracts,  may
be  beneficial  to both  parties  provided  such  publications  are  subject  to
reasonable controls to protect Confidential  Information.  In particular,  it is
the intent of the parties to maintain the  confidentiality  of any  Confidential
Information included in any foreign patent application until such foreign patent
application has been published.  Accordingly, each party shall have the right to
review and  approve  any paper  proposed  for  publication  by the other  party,
including oral  presentations and abstracts,  which utilizes data generated from
the Collaborative Alliance and/or includes Confidential Information of the other
party.  Before any such paper is submitted for publication,  the party proposing
publication  shall  deliver a complete  copy to the other party at least 45 days
prior to submitting the paper to a publisher.  The receiving  party shall review
any such paper and give its comments to the  publishing  party within 30 days of
the  delivery  of such  paper  to the  receiving  party.  With  respect  to oral
presentation materials and abstracts,  the parties shall make reasonable efforts
to expedite review of such materials and abstracts,  and shall return such items
as soon as practicable to the publishing  party with  appropriate  comments,  if
any,  but in no  event  later  than 30 days  from the  date of  delivery  to the
receiving  party.  The  publishing  party shall  comply  with the other  party's
request to delete references to such other party's  Confidential  Information in
any such paper and agrees to withhold  publication of same for an additional 180
days to permit the parties to obtain patent protection, if either of the parties
deem  it   necessary,   in  accordance   with  the  terms  of  this   Agreement.
Notwithstanding the foregoing,  GENEMEDICINE shall have the right to present and
publish all studies  using a NFID  performed  prior to the Effective  Date,  and
BIOJECT shall have the right to present and publish all studies using  BIOJECT's
NFID with a Direct  Competitor's  Gene Delivery  System  performed  prior to the
Effective Date.

                                    ARTICLE 9
                         REPRESENTATIONS AND WARRANTIES

          9.1 Corporate  Power.  Each party hereby  represents and warrants that
such party is duly organized and validly existing under the laws of the state of
its  incorporation and has full corporate power and authority to enter into this
Agreement and to carry out the provisions hereof.

          9.2 Due Authorization.  Each party hereby represents and warrants that
such party is duly  authorized  to execute and  deliver  this  Agreement  and to
perform its obligations hereunder.

          9.3 Binding Obligation. Each party hereby represents and warrants that
this  Agreement  is a  legal  and  valid  obligation  binding  upon  it  and  is
enforceable  in  accordance  with  its  terms.   The  execution,   delivery  and
performance  of  this  Agreement  by such  party  does  not  conflict  with  any
agreement, instrument or understanding,  oral or written, to which it is a party
or by which it may be bound,  nor  violate any law or  regulation  of any court,
governmental body or administrative or other agency having authority over it.





          9.4 Limitation on  Warranties.  Nothing herein shall be construed as a
representation  or  warranty by either  party to the other that any  Contributed
Technology  under  the  Control  of such  party is  valid,  enforceable,  or not
infringed  by any Third  Party,  or that the  practice  of such  rights does not
infringe any intellectual property right of any Third Party. Neither party makes
any warranties,  express or implied, concerning the success of the Collaborative
Alliance or the commercial utility of any Products.

          9.5  Disclaimer of  Warranties.  EXCEPT AS EXPRESSLY SET FORTH IN THIS
AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATION OR WARRANTY TO THE OTHER PARTY
OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING,  WITHOUT LIMITATION, ANY WARRANTY OF
NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

          9.6  Limitation  of  Liability.  NEITHER  PARTY  SHALL BE  ENTITLED TO
RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL,  CONSEQUENTIAL OR PUNITIVE
DAMAGES IN CONNECTION WITH THE COLLABORATIVE ALLIANCE.

          9.7 Mutual Indemnification.  Each party hereby agrees to save, defend,
indemnify  and hold  harmless  the  other  party  and its  officers,  directors,
employees,  consultants and agents from and against any and all losses, damages,
liabilities,   expenses  and  costs,  including  reasonable  legal  expense  and
attorneys' fees ("Losses"),  to which the indemnified parties may become subject
as a result of any claim, demand,  action or other proceeding by any Third Party
to the  extent  such  Losses  arise  out of, or are  based  upon,  the use of an
indemnifying  party's  Contributed  Technology by the  indemnified  party or its
Affiliates, except to the extent such Losses result from the gross negligence or
willful misconduct of the party claiming a right of  indemnification  under this
Section 9.7. In the event either party seeks  indemnification under this Section
9.7,  it  shall  inform  the  other  party  of a claim  as  soon  as  reasonably
practicable after it receives notice of the claim,  shall permit the other party
to assume direction and control of the defense of the claim (including the right
to settle the claim solely for monetary  consideration),  and shall cooperate as
requested (at the expense of the other party) in the defense of the claim.

                                   ARTICLE 10
                              TERM AND TERMINATION

          10.1 Term.  This Agreement shall begin on the Effective Date and shall
continue for 18 months from the Effective  Date,  unless  extended or terminated
earlier by mutual  written  agreement of the parties (the  "Term").  The parties
agree to meet and evaluate whether to extend the Term under mutually  acceptable
terms at least 60 days prior to the end of the Term.

          10.2 Termination for Cause.  Either party may terminate this Agreement
prior to the expiration of the Term upon the occurrence of any of the following:

               (a) Upon or after  the  bankruptcy,  insolvency,  dissolution  or
winding up of the other  party  (other  than  dissolution  or winding up for the
purposes of reconstruction or amalgamation);

               (b) Upon or after the breach of any  material  provision  of this
Agreement  by the other party if the  breaching  party has not cured such breach
within 30 days after written notice thereof by the non-breaching party; or

               (c) Upon or after the  transfer  or sale of all or  substantially
all of the business of the other party to which this Agreement relates,  whether
by merger,  sale of stock, sale of assets or otherwise,  except to an Affiliate,
following 60 days' prior written notice to the other party.

          10.3 Effect of Expiration or Termination.

               (a) Expiration or termination of this Agreement shall not relieve
the parties of any obligation  accruing prior to such expiration or termination.
Except as set forth below or elsewhere in this  Agreement,  the  obligations and
rights of the parties  under  Sections 7.1, 8.1, 9.4, 9.5, 9.6, 9.7 and 10.3 and
Articles 1, 12 and 13 shall survive expiration or termination of this Agreement.

               (b) Upon  termination of this Agreement by GENEMEDICINE  pursuant
to Section 10.2, Section 2.2(b) shall survive for a period of 18 months from the
Effective  Date.  Upon  termination  of this  Agreement  by BIOJECT  pursuant to
Section  10.2,  Section  2.2(a) shall survive for a period of 18 months from the
Effective Date.





               (c) Upon expiration or termination of this Agreement,  each party
shall  cease  all  activities  under  the  Collaborative  Alliance,  except  for
activities  required  for each  party  to  fulfill  its  obligations  under  any
agreement with a Corporate Partner; provided,  however, that BIOJECT will have a
non-exclusive,  worldwide,  fully-paid,  irrevocable  license to use information
generated from animal and/or human studies involving  BIOJECT's NFIDs (including
Dermal Devices and Biojectors) in combination  with  GENEMEDICINE's  proprietary
Gene Delivery Systems in the course of the Collaborative  Alliance to enter into
collaborative business relationships with Third Parties.

               (d) Upon  expiration or  termination  of this Agreement and for a
period of six months  thereafter,  each party will use  commercially  reasonable
efforts to include the other party in any collaborative agreement with any Third
Party in the Field.  Notwithstanding  the foregoing,  a party may proceed with a
collaborative agreement with a Third Party without obligation to the other party
if such Third Party does not wish to enter into a  collaborative  agreement with
the other party.

               (e) In the event of the  bankruptcy,  insolvency,  dissolution or
winding up of a party (other than  dissolution or winding up for the purposes of
reconstruction  or  amalgamation),  all rights of such party in the Joint Patent
Rights  shall  hereby be assigned to the other party to this  Agreement,  or, if
such assignment is prohibited, such party shall hereby grant to such other party
an exclusive,  worldwide,  fully-paid,  irrevocable  license to the Joint Patent
Rights.

                                   ARTICLE 11
                                    PUBLICITY

          11.1 Publicity  Review.  BIOJECT and GENEMEDICINE will jointly discuss
and agree,  based on the  principles  of Section  11.2,  on any statement to the
public  regarding the execution and the subject  matter of this Agreement or any
other aspect of this Agreement,  except with respect to disclosures  required by
law or  regulation.  Within 30 days  following the Effective  Date,  the parties
shall issue a joint press release. Neither party shall use the name of the other
party in any public  statement,  prospectus,  annual  report,  or press  release
without  the  prior  written  approval  of the  other  party,  which  may not be
unreasonably withheld or delayed;  provided,  however, that either party may use
the name of the other party in any public statement,  prospectus, annual report,
or press release without the prior written  approval of the other party, if such
party is advised by counsel  that such  disclosure  is  required  to comply with
applicable law.

          11.2 Standards. In the discussion and agreement referred to in Section
11.1, the principles observed by BIOJECT and GENEMEDICINE will be accuracy,  the
requirements for  confidentiality  under Section 8.1, the advantage a competitor
of BIOJECT or  GENEMEDICINE  may gain from any public or Third Party  statements
under Section 11.1, the  requirements of disclosure under any securities laws or
regulations  of the  United  States,  including  those  associated  with  public
offerings, and the standards and customs in the pharmaceutical industry for such
disclosures by companies comparable to BIOJECT and GENEMEDICINE.

                                   ARTICLE 12
                               DISPUTE RESOLUTION

          12.1  Disputes.  The  parties  recognize  that  disputes as to certain
matters may from time to time arise which relate to either party's rights and/or
obligations  hereunder.  It  is  the  objective  of  the  parties  to  establish
procedures to facilitate the resolution of such disputes in an expedient  manner
by mutual  cooperation  and without  resort to  litigation.  To accomplish  this
objective,  the parties agree to follow the procedures set forth in this Section
12.1 if and when such a dispute arises between the parties.





          12.2 Procedures. If any dispute arises between the parties relating to
the  interpretation,  breach or performance of this Agreement or the grounds for
the  termination  thereof,  and the parties cannot resolve the dispute within 30
days of a written request by either party to the other party,  the parties agree
to hold a meeting,  attended by the Chief Executive Officer or President of each
party,  to attempt in good faith to negotiate a resolution  of the dispute prior
to pursuing  other  available  remedies.  If,  within 60 days after such written
request,  the parties have not  succeeded  in  negotiating  a resolution  of the
dispute,  such dispute shall be submitted to final and binding arbitration under
the then current  commercial  rules and regulations of the American  Arbitration
Association  ("AAA")  relating  to  voluntary   arbitrations.   The  arbitration
proceedings  shall be held in Wilmington,  Delaware.  The  arbitration  shall be
conducted by one arbitrator, who is knowledgeable in the subject matter at issue
in the dispute and who will be selected by mutual  agreement  of the parties or,
failing such agreement, shall be selected in accordance with the AAA rules. Each
party shall  initially  bear its own costs and legal fees  associated  with such
arbitration.  The prevailing party in any such arbitration  shall be entitled to
recover from the other party the reasonable  attorneys' fees, costs and expenses
incurred by such  prevailing  party in  connection  with such  arbitration.  The
decision  of the  arbitrator  shall be final and  binding  on the  parties.  The
arbitrator shall prepare and deliver to the parties a written,  reasoned opinion
conferring its decision. Judgment on the award so rendered may be entered in any
court having competent jurisdiction thereof.

                                   ARTICLE 13
                                  MISCELLANEOUS

          13.1 Assignment.  Except as expressly provided hereunder, neither this
Agreement nor any rights or obligations  hereunder nor a party's interest in the
Joint  Patent  Rights may be assigned or otherwise  transferred  by either party
without the prior written consent of the other party, which consent shall not be
unreasonably  withheld;  provided,  however,  that either  party may assign this
Agreement  and its rights and  obligations  hereunder  without the other party's
consent (a) to an Affiliate,  (b) in connection with the transfer or sale of all
or  substantially  all of the  assets  relating  to the  subject  matter of this
Agreement to another party, or (c) in the event of a merger or reorganization of
such party with or into another party, and, in the event of such assignment, the
assigning  party shall provide  written notice to the other party within 30 days
after such assignment. In the event of such transaction,  however,  intellectual
property rights  (including  Know-How) of a party to such transaction other than
one of the  parties to this  Agreement  (the  "Acquiring  Party"),  shall not be
included in the Contributed  Technology licensed hereunder.  Notwithstanding the
foregoing,  any such  assignment to an Affiliate shall not relieve the assigning
party of its  responsibilities  for  performance of its  obligations  under this
Agreement.  The rights and obligations of the parties under this Agreement shall
be binding upon and inure to the benefit of the successors and permitted assigns
of the parties.  Any assignment not in accordance  with this Agreement  shall be
void.

          13.2 Force Majeure.  Neither party shall be held liable or responsible
to the  other  party  nor be deemed to have  defaulted  under or  breached  this
Agreement  for failure or delay in  fulfilling  or  performing  any term of this
Agreement  when such failure or delay is caused by or results from causes beyond
the reasonable  control of the affected  party,  including,  but not limited to,
fire,  floods,  embargoes,  war,  acts of war  (whether war be declared or not),
insurrections,  riots,  civil  commotions,  strikes,  lockouts  or  other  labor
disturbances,  acts  of God or  acts,  omissions  or  delays  in  acting  by any
governmental authority or the other party.

          13.3 Governing Law. This Agreement shall be governed by, and construed
and enforced in accordance with, the laws of the State of Delaware, as such laws
are applied to contracts  entered into and to be performed  entirely  within the
State of Delaware by Delaware residents, and the laws of the United States.

          13.4 Waiver.  Except as specifically  provided for herein,  the waiver
from  time to time by  either  of the  parties  of any of their  rights or their
failure to exercise any remedy shall not operate or be construed as a continuing
waiver of same or of any other of such  party's  rights or remedies  provided in
this Agreement.

Exhibits attached hereto) sets forth all of the covenants, promises, agreements,

Agreement shall be binding upon the parties hereto unless reduced to writing and
