unauthorized dissemination of Confidential Information as it employs for its own
information of a similar nature that it does not want to have disseminated. In
the event a Receiving Party is requested or required by a governmental,
quasi-governmental, judicial or quasi-judicial entity to disclose Confidential
Information it received from the Disclosing Party, it shall not be a violation
of this License and Supply Agreement to comply provided, however, that the
Receiving Party so requested or required shall notify the Disclosing Party of
such request or requirement, promptly upon receipt of the same.

         6.03 Commercial Use. The parties hereto agree that neither shall put
the Confidential Information of the other Party to any use, except as expressly

                                  Infringement.

         8.01 Claim. In the event of any claim, action or allegation by a third

Influenza Product in which an Adjuvant, a Novasome(R) delivery system, Novavax's

portion or aspect thereof, is utilized in connection therewith or incorporated
therein, Novavax will pay all damages, royalties and costs awarded in any such
action, and all attorney's fees and costs incurred by Parkedale in its defense
to any such allegation, claim, and/or action. Parkedale agrees to notify Novavax
promptly upon learning that the claim might be asserted.  Novavax agrees that
Parkedale and Novavax shall have joint control over the defense of any
allegation, claim, and/or action and any negotiation for its settlement or

<PAGE>   18


its use with or in an Influenza Product or Parkedale's use thereof, or an
injunction or order shall be obtained against Parkedale's use of the Novavax IP,
or any portion or aspect thereof, by reason of any such claim, action or
allegation, Parkedale shall have the right, without in any way limiting the

obtained knowledge, of the existence of the applicable allegation, claim and/or
of infringement or violation. Novavax agrees to indemnify and hold Parkedale
harmless for all costs and damages incurred by Parkedale as a result of any such
allegation, claim, and/or action.

         8.03 Non-Influenza Product Claim. In the event of any claim, action or
allegation by a third Party asserting or involving a patent, copyright or
trademark or any other intellectual property right, which solely concerns an
Adjuvant, a Novasome(R) delivery system, Novavax's Know-How, a Novavax
Improvement, the Novavax IP and/or Patent Rights, or any portion or aspect
thereof, which is outside of the Field and has no bearing on the development,
manufacture, use, offer-for-sale, sale, importation and/or exportation of an
Influenza Product of any kind whatsoever, Novavax will pay all damages,
royalties and costs awarded in any such action, and all attorney's fees and
costs incurred by Novavax in its defense to any such allegation, claim and/or
action. Novavax agrees to notify Parkedale promptly upon learning of any such
allegation, claim and/or action and that such allegation, the claim and/or
action might be asserted. Novavax agrees that it shall not adopt, advocate or

upon the terms and/or purpose of this License and Supply Agreement. Parkedale
agrees that Novavax shall have sole control over the defense of any such
allegation, claim and/or action and any negotiation for its settlement or
compromise, and Novavax shall have the right to settle any claim on behalf of
Novavax, so long as such settlement or compromise in no way frustrates or
negatively impact upon the terms and purpose of this License and Supply
Agreement. Parkedale agrees to provide Novavax with reasonable assistance, at
Novavax's expense, in the defense of any such allegation, claim, and/or action.

         8.03 Notice of Third Party Infringement. If either Novavax or Parkedale
learns that the Novavax IP, or any portion or aspect thereof, is allegedly
infringed or contributorily infringed or misappropriated by a third Party, the
Party learning of the alleged infringement or contributory infringement shall
promptly notify the other Party. Within 30 days after learning of such
infringement or contributory infringement, the parties shall jointly determine
whether or not to bring an action against the alleged infringer or
misappropriator, and who shall bring such action.

         8.04 Parkedale Action for Third Party Infringement. In the event that
Parkedale brings an action for infringement, contributory infringement,
misappropriation and/or violation of any other intellectual property right
concerning an Influenza Product or the Novavax IP, or any aspect or portion
thereof, in the name of Novavax and/or the name of Parkedale, Novavax shall
cooperate with Parkedale, and Parkedale will bear all costs and the expenses
relating to the litigation, including those incurred by Novavax. Parkedale shall
be entitled to keep all damages, royalties, legal fees, costs, and other
recoveries awarded in such litigation. Novavax agrees that Parkedale shall have
the

                                       18
<PAGE>   19
first right to prosecute any claims and/or actions concerning an Influenza
Product or the Novavax IP, or any portion or aspect thereof, which relates to,
concerns or results from its use with or in an Influenza Product.

         8.05 Novavax Right to Prosecute Third Party Infringement. In the event
that Parkedale decides not to initially bring an action for infringement, for
contributory infringement, misappropriation and/or any other intellectual
property violation of the Novavax IP, then Novavax shall have the right, but not
the obligation, to bring an action in the name of Novavax and/or the name of
Parkedale. Parkedale will cooperate with Novavax at Novavax's expense. Novavax
shall bear all costs and expenses relating to the litigation, including those
incurred by Parkedale, and Novavax will be entitled to all damages and other
recoveries awarded in such litigation.

         8.06 Novavax Right to Join Parkedale Prosecution of Third Party
Infringement. If, after Novavax fails to cause such infringement,
misappropriation or any other intellectual property right violation to terminate
or cease or to bring a suit or action to compel termination or cessation
pursuant to Paragraph 8.05 above, and Parkedale elects to initiate suit or
action to compel termination or cessation, Novavax independently shall have the
right to join any such suit or action brought by Parkedale and, in such event,
Novavax shall pay one-half of the cost of such suit or action from the date of
joining.

         8.07 Recovery in a Third Party Infringement Action. Upon final
disposition of any event described in Paragraphs 8.05 or 8.06 above,
any recovery obtained shall be distributed as follows: (a) each Party shall be
reimbursed for any expenses incurred in the action; (b) as to ordinary damages,
Parkedale shall receive an amount equal to its lost profits or a reasonable
royalty on the infringing sales (whichever measure of damages the court shall
have applied), less a reasonable approximation of the royalties (I) that
Parkedale would have paid to Novavax if Parkedale had sold the infringing
products and services rather than the infringer, or (ii) of the reasonable
royalty on the infringing sales awarded to Parkedale (whichever measure of
damages the court shall have applied), which amount will be distributed to
Novavax; and (c) Parkedale shall receive 100% of any special, punitive or other
damages. Parkedale may offset any expenses incurred under this Article VIII
against any royalty payments due to Novavax.

         8.08 Cooperation of Each Party in Third Party Infringement Action. In
any infringement, misappropriation and/or intellectual property violation suit
as either Party may institute to enforce the Patent Rights pursuant to this
License and Supply Agreement, the other Party hereto shall, at the request and
expense of the Party initiating such suit, cooperate in all respects and, to the
extent possible, have its employees testify when requested and make available
relevant records, papers, information, samples and the like.

                                   ARTICLE IX
                             Term and Termination.

         9.01 Term. The term of this License and Supply Agreement shall be the
period beginning on the date of execution by both parties to this License and
Supply Agreement, i.e., the Effective Date, and continuing for the period that
any portion or aspect of the Novavax IP is proprietary to Novavax, unless
earlier terminated under Paragraphs 9.02 and 9.03 below or otherwise,
and so long as this License and Supply Agreement provides Parkedale with
exclusivity with respect to the Influenza Product in the Territory (the "Term").
Thereafter, this License and Supply Agreement shall automatically be renewed for
successive 12-month periods (the "Renewal Periods"), unless either Party gives
notice of non-renewal to the other Party at least ninety (90) days before the
then-current expiration date. In the event that a generic product to an
Influenza Product is approved for use in the Field within the Territory, Novavax
agrees that the obligation for Parkedale to pay royalties pursuant to Article
III, Paragraph 3.03 above shall cease and terminate upon such immediate generic
approval.

         9.02 Termination by Novavax. Novavax may terminate this License and
Supply Agreement upon ninety (90) days written notice to Parkedale, upon the
occurrence of any termination event as follows: (a) Parkedale or any of its
employees breaches any obligation under this License and Supply Agreement,
including without limitation violation of any payment terms, if such breach is
not cured within thirty (30) days after Novavax demands its cure in writing; or
(b) Parkedale becomes insolvent, enters into reorganization or bankruptcy, makes
a general assignment for the benefit of creditors, admits in writing its
inability to pay debts as they mature, suffers or permits the appointment of a
receiver for its business or assets, or avails itself of or becomes subject to
any other judicial or administrative proceeding related to insolvency or
protection of creditors' rights (and, if such action or proceeding is
involuntary on the part of Parkedale, such action or proceeding is not dismissed
within 90 days).

         9.03 Termination by Parkedale. Parkedale may terminate this License and
Supply Agreement upon ninety (90) days written notice to Novavax, upon the
occurrence of any termination event as follows: (a) Novavax or any of its
employees breaches any obligation under this License and Supply Agreement,
including without limitation violation of any payment terms, if such breach is
not cured within thirty (30) days after Parkedale demands its cure in writing;
or (b) Novavax becomes insolvent, enters into reorganization or bankruptcy,
makes a general assignment for the benefit of creditors, admits in writing its
inability to pay debts as they mature, suffers or permits the appointment of a
receiver for its business or assets, or avails itself of or becomes subject to
any other judicial or administrative proceeding related to insolvency or
protection of creditors' rights (and, if such action or proceeding is
involuntary on the part of Novavax, such action or proceeding is not dismissed
within 90 days).

         9.04 Effect of Termination. From and after the date of any expiration
or termination of this License and Supply Agreement, neither Party shall have
any further rights, privileges, or obligations hereunder except that: (a) such
expiration or termination shall not relieve either Party of any

                                       20
<PAGE>   21


liability or obligation accrued prior to the effective date of expiration or
termination; (b) such expiration or termination shall not affect the continued
operation or enforcement of any provision of this License and Supply Agreement
which is to survive expiration or termination; and (c) upon such expiration or
termination, each Party shall immediately return to the other Party all
Confidential Information as required by Article VI of this License and Supply
Agreement. In no event upon the expiration or termination of this License and
Supply Agreement shall the terminating Party (or in the case of expiration of
this License and Supply Agreement, any Party) be liable to the other Party for
any damages, indemnities, loss of profits, loss of revenues, or other losses by
reason of any such expiration or termination, unless the License and Supply
Agreement is wrongfully terminated.

                                    ARTICLE X
                                  Miscellaneous

         10.01 Authority. Each Party represents and warrants to the other that
it has the right, and has obtained all necessary corporate approvals, to enter
into this License and Supply Agreement and perform the obligations to be
performed by it under this License and Supply Agreement and that this License
and Supply Agreement constitutes its valid, binding and enforceable obligation,
enforceable against it in accordance with its terms.

         10.02 Force Majeure. The failure of either Party hereto to perform any
obligation under this License and Supply Agreement (except any payment
obligation hereunder of Parkedale to Novavax) due to acts of God, acts of
government, civil disturbances, wars, strikes, transportation problems,
unreasonable delay by vendors in delivery, failure to provide products or
materials by its vendors, or other causes beyond its reasonable control shall
not be deemed to be a breach of this License and Supply Agreement; provided,
however, that the Party so prevented from complying herewith shall immediately
give notice thereof to the other Party and shall continue to take all
commercially reasonable actions to comply as fully as possible herewith. After
removal of the basis for the nonperformance, the Party failing to perform shall
resume performance within a reasonable time.

         10.03 Entire Agreement. This License and Supply Agreement, together
with its Exhibits, constitutes the sole and entire agreement between the parties
relating to the subject matter herein, and terminates and supersedes any and all
prior agreements and understandings between the parties.

         10.04 Waiver and Amendment. No change in, addition to, or waiver of
any of the terms and provisions herein shall be binding upon any Party unless
approved by it in writing by both parties hereto.

         10.05 No Waiver. The failure by any Party to exercise or to enforce any
of the terms or conditions of this License and Supply Agreement shall not
constitute or be deemed a waiver of that Party's right thereafter to enforce
each and every term and condition of this License and Supply Agreement.

         10.06 Severability. Should a court of law or arbitrator hold that any
one or more of the provisions in this License and Supply Agreement is invalid,
illegal or unenforceable, no other provision of this License and Supply
Agreement shall be affected thereby, and the remaining provisions of this
License and Supply Agreement shall be both construed and reformed and shall
continue with the same effect as if such unenforceable, illegal or invalid
provision shall not have been inserted in this License and Supply Agreement.

         10.07 Governing Law. This License and Supply Agreement and the
