trustees, officers, faculty, students, employees, and agents and their respective successors, heirs
and assigns (the “Indemnitees”), against any liability, damage, loss, or expense (including
reasonable attorneys fees and expenses of litigation) incurred by or imposed upon any of the
Indemnitees in connection with any claims, suits, actions, demands or judgments arising out of any
theory of liability (including without limitation actions in the form of tort, warranty, or strict
liability and regardless of whether such action has any factual basis) concerning any product,
process, or service that is made, used, or sold pursuant to any right or license granted under this
Agreement; provided, however, that such indemnification shall not apply to any liability, damage,
loss, or expense to the extent directly attributable to (i) the negligent activities or intentional
misconduct of the Indemnitees or (ii) the settlement of a claim, suit, action, or demand by
Indemnitees without the prior written approval of Company.




- 6 -









 








          (b) Procedures. The Indemnitees agree to provide Company with prompt written notice of any
claim, suit, action, demand, or judgment for which indemnification is sought under this Agreement.
Company agrees, at its own expense, to provide attorneys reasonably acceptable to Medical School to
defend against any such claim. The Indemnitees shall cooperate fully with Company in such defense
and will permit Company to conduct and control such defense and the disposition of such claim,
suit, or action (including all decisions relative to litigation, appeal, and settlement); provided,
however, that any Indemnitee shall have the right to retain its own counsel, at the expense of
Company, if representation of such Indemnitee by the counsel retained by Company would be
inappropriate because of actual or potential differences in the interests of such Indemnitee and
any other party represented by such counsel. Company agrees to keep Medical School informed of the
progress in the defense and disposition of such claim and to consult with Medical School with
regard to any proposed settlement.




          (c) Insurance. Company shall maintain insurance or self-insurance that is reasonably adequate
to fulfill any potential obligation to the Indemnitees, but in any event not less than one million
dollars ($1,000,000) for injuries to any one person arising out of a single occurrence and five
million dollars ($5,000,000) for injuries to all persons arising out of a single occurrence.
Company shall provide Medical School, upon request, with written evidence of such insurance or
self-insurance. Company shall continue to maintain such insurance or self-insurance after the
expiration or termination of this Agreement during any period in which Company or any Affiliate or

     3.5. Compliance with Law. Company shall comply with, and shall ensure that its Affiliates and
Sublicensees (to the extent commercially feasible) comply with, all local, state, federal, and
international laws and regulations relating to the development, manufacture, use, and sale of
Licensed Products. Company expressly agrees to comply with the following:




     (a) Company or its Affiliates or Sublicensees shall obtain all necessary approvals from
the United States Food & Drug Administration and any similar governmental authorities of any
foreign jurisdiction in which Company or an Affiliate or Sublicensee intends to make, use,
or sell Licensed Products.




     (b) Company and its Affiliates and Sublicensees shall comply with all United States
laws and regulations controlling the export of certain commodities and technical

data,
including without limitation all Export Administration Regulations of the United
States Department of Commerce. Among other things, these laws and regulations prohibit, or
require a license for, the export of certain types of commodities and technical data to
specified countries. Company hereby gives written assurance that it will comply with, and
will cause its Affiliates and Sublicensees to comply with, all United States export control
laws and regulations, that it bears sole responsibility for any violation of such laws and
regulations by itself or its Affiliates or Sublicensees, and that it will indemnify, defend,
and hold Medical School harmless (in accordance with Section 3.2.) for the consequences of
any such violation.




     (c) To the extent that any invention claimed in the Patent Rights has been partially
funded by the United States government, and only to the extent required by applicable laws
and regulations, Company agrees that any Licensed Products used or sold in the United States
will be manufactured substantially in the United States or its territories. Current law
provides that if domestic manufacture is not commercially feasible under the circumstances,

under this Agreement shall be reduced by reason of any withholding or similar taxes applicable to
such payments to Medical School, which shall be paid by Company as required by applicable law and
reported by Company to the Medical School.



6. Patents and Infringement.




     6.1. Responsibility for Medical School Patent Rights. Medical School shall have primary
responsibility, at the expense of Company, for the preparation, filing, prosecution, and
maintenance of all Medical School Patent Rights, using patent counsel reasonably acceptable to
Company. Medical School shall consult with Company as to the preparation, filing, prosecution, and
maintenance of all such Patent Rights reasonably prior to any deadline or action with the U.S.
Patent & Trademark Office or any foreign patent office and shall furnish Company with copies of all
relevant documents reasonably in advance of such consultation.



     6.2. Responsibility for Joint Patent Rights. Company shall have primary responsibility, at
its expense, for the preparation, filing, prosecution, and maintenance of all Joint Patent Rights,
using patent counsel reasonably acceptable to Medical School. Company shall consult with Medical
School as to the preparation, filing, prosecution, and maintenance of all such Patent Rights
reasonably prior to any deadline or action with the U.S. Patent & Trademark Office or any foreign
patent office and shall furnish Medical School with copies of all relevant documents reasonably in
advance of such consultation.



     6.3. Cooperation. Medical School and Company shall cooperate fully in the preparation,
filing, prosecution, and maintenance of all Patent Rights. Such cooperation includes, without



- 12 -









 







limitation, (a) promptly executing all papers and instruments or requiring employees of Medical
School or Company to execute such papers and instruments as reasonable and appropriate so as to
enable Medical School or Company to file, prosecute, and maintain such Patent Rights in any
country; and (b) promptly informing the other party of matters that may affect the preparation,
filing, prosecution, or maintenance of any such Patent Rights (such as becoming aware of an
additional inventor who is not listed as an inventor in a patent application).



     6.4. Payment of Expenses. Within thirty (30) days after Medical School invoices Company,
Company shall reimburse Medical School for all reasonable patent-related expenses incurred by
Medical School pursuant to Section 6.1. Company may elect, upon sixty (60) days written notice to
Medical School, to cease payment of the expenses associated with obtaining or maintaining patent
protection for one or more Patent Rights in one or more countries. In such event, Company shall
lose all rights under this Agreement with respect to such Patent Rights in such countries for which
it has elected not to pay.



     6.5. Abandonment. In the event that a party desires to abandon any patent or patent
application within the Patent Rights for which it has primary responsibility, such party shall
provide the other party with reasonable prior written notice of such intended abandonment or
decline of responsibility, and the other party shall have the right, at its expense, to prepare,
file, prosecute, and maintain the relevant Patent Rights.



     6.6. Grant back: The Company agrees that for any patent rights, as defined in the sponsored
research agreement that implements Company’s obligation in Section 3.1(e) that it has not licensed,
the Company grants back to the Medical School, without limiting in any way its rights under this
Agreement, a non-exclusive license to the Patent Rights in order that the Medical School may
license the patent rights from the sponsored research to third parties. Medical School shall pay
Company {***} of any revenues or other consideration received by Medical School with respect to any
patent rights granted back by Company pursuant to this Section 6.6.



     6.7. Infringement.



          (a) Notification of Infringement. Each party agrees to provide written notice to the other
party promptly after becoming aware of any infringement of the Patent Rights.




          (b) Company Right to Prosecute. So long as Company remains the only licensee of the Patent
Rights and Biological Materials in the Field, Company shall have the right, under its own control
and at its own expense, to prosecute any third party infringement of the Patent Rights in the Field
or, together with licensees of the Patent Rights in other fields (if any), to defend the Patent
Rights in any declaratory judgment action brought by a third party which alleges invalidity,
unenforceability, or non-infringement of the Patent Rights. Prior to commencing any such action,
Company shall consult with Medical School and shall consider the views of Medical School regarding
the advisability of the proposed action and its effect on the public interest. Company shall not
enter into any settlement, consent judgment, or other voluntary final disposition of any
infringement action under this Subsection without the prior written consent of Medical School,
which consent shall not be unreasonably withheld or delayed.




- 13 -









 







Any recovery obtained in an action under this Subsection shall be distributed as follows: (i)
each party shall be reimbursed for any expenses incurred in the action (including the amount of any
royalty payments withheld from Medical School as described below), (ii) as to ordinary damages,
Company 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 that Company would have paid to Medical School if Company had sold the infringing
products and services rather than the infringer, and (iii) as to special or punitive damages, the
parties shall share equally in any award. Company may offset a total of fifty percent (50%) of any
expenses incurred under this Subsection against any royalty payments due to Medical School under
this Agreement, provided that in no event shall the royalty payments under Section 4.5. and 4.7.,
when aggregated with any other offsets and credits allowed under this Agreement, be reduced by more
than fifty percent (50%) in any Royalty Period.




          (c) Medical School as Indispensable Party. Medical School shall permit any action under this
Section to be brought in its name if required by law, provided that Company shall hold Medical
School harmless from, and if necessary indemnify Medical School against, any costs, expenses, or
liability that Medical School may incur in connection with such action.




          (d) Medical School Right to Prosecute. In the event that Company fails to initiate an
infringement action within a reasonable time after it first becomes aware of the basis for such
action, or to answer a declaratory judgment action within a reasonable time after such action is
filed, Medical School shall have the right to prosecute such infringement or answer such
declaratory judgment action, under its sole control and at its sole expense, and any recovery
obtained shall be given to Medical School.




          (e) Cooperation. Each party agrees to cooperate fully in any action under this Section 6.7.
which is controlled by the other party, provided that the controlling party reimburses the
cooperating party promptly for any costs and expenses incurred by the cooperating party in
connection with providing such assistance.

the subject matter of the Patent Rights, except as otherwise provided by written agreement between
Medical School and Company (e.g., a sponsored research agreement).



     7.3. Publicity Restrictions. Company shall not use the name of Medical School or any of its
trustees, officers, faculty, students, employees, or agents, or any adaptation of such names, or
any terms of this Agreement in any promotional material or other public announcement or disclosure
without the prior written consent of Medical School. The foregoing notwithstanding, Company shall
have the right to disclose such information without the consent of Medical School in any
prospectus, offering memorandum, or other document or filing required by applicable securities laws
or other applicable law or regulation, provided that Company shall have given Medical School at
least ten (10) days (or such prior shorter period in order to enable Company to make a timely
announcement, while affording the Medical School the maximum



- 15 -









 







feasible time to review the
announcement) prior written notice of the proposed text for the purpose of giving Medical School
the opportunity to comment on such text.



8. Term and Termination.




     8.1. Term. This Agreement shall commence on the Effective Date and shall remain in effect
until (a) the expiration of all issued patents within the Patent Rights or (b) for a period of ten
(10) years after the Effective Date if no such patents have issued within that ten-year period,
unless earlier terminated in accordance with the provisions of this Agreement.



     8.2. Termination for Default. In the event that either party commits a material breach of its
obligations under this Agreement and fails to cure that breach within sixty (60) days after
receiving written notice thereof, the other party may terminate this Agreement immediately upon
written notice to the party in breach. If the alleged breach involves nonpayment of any amounts
due Medical School under this Agreement, Company shall have only one opportunity to cure a material
breach for which it receives notice as described above; any subsequent material breach by Company
will entitle Medical School to terminate this Agreement immediately upon written notice to Company,
without the sixty-day cure period.



     8.3. Force Majeure. Neither party will be responsible for delays resulting from causes beyond
the reasonable control of such party, including without limitation fire, explosion, flood, war,
strike, or riot, provided that the nonperforming party uses commercially reasonable efforts to
avoid or remove such causes of nonperformance and continues performance under this Agreement with
reasonable dispatch whenever such causes are removed.



     8.4. Effect of Termination. The following provisions shall survive the expiration or
termination of this Agreement: Articles 1 and 9; Sections 3.2., 3.5., 5.2. (obligation to provide
final report and payment), 5.5., 6.4., 7.1., 7.3., 8.4., and 10.9. Upon the early termination of
this Agreement, Company and its Affiliates and Sublicensees may complete and sell any
work-in-progress and inventory of Licensed Products that exist as of the effective date of
termination, provided that (a) Company is current in payment of all amounts due Medical School
under this Agreement, (b) Company pays Medical School the applicable royalty on such sales of
Licensed Products in accordance with the terms and conditions of this Agreement, and (c) Company
and its Affiliates and Sublicensees shall complete and sell all work-in-progress and inventory of
Licensed Products within six (6) months after the effective date of termination.



9. Dispute Resolution.




     9.1. Procedures Mandatory. The parties agree that any dispute arising out of or relating to
this Agreement shall be resolved solely by means of the procedures set forth in this Article, and
that such procedures constitute legally binding obligations that are an essential provision of this
Agreement; provided, however, that all procedures and deadlines specified in this Article may be
modified by written agreement of the parties. If either party fails to observe the procedures of
this Article, as modified by their written agreement, the other party may bring an action for
specific performance in any court of competent jurisdiction.



- 16 -









 





     9.2. Dispute Resolution Procedures.



          (a) Negotiation. In the event of any dispute arising out of or relating to this Agreement,
the affected party shall notify the other party, and the parties shall attempt in good faith to
resolve the matter within ten (10) days after the date of such notice (the “Notice Date”). Any
disputes not resolved by good faith discussions shall be referred to senior executives of each
party, who shall meet at a mutually acceptable time and location within thirty (30) days after the
Notice Date and attempt to negotiate a settlement.




          (b) Mediation. If the matter remains unresolved within sixty (60) days after the Notice Date,
or if the senior executives fail to meet within thirty (30) days after the Notice Date, either
party may initiate mediation upon written notice to the other party, whereupon both parties shall
be obligated to engage in a mediation proceeding under the then current Center for Public Resources
(“CPR”) Model Procedure for Mediation of Business Disputes, except that specific provisions of this
Section shall override inconsistent provisions of the CPR Model Procedure. The mediator will be
selected from the CPR Panels of Neutrals. If the parties cannot agree upon the selection of a
mediator within ninety (90) days after the Notice Date, then upon the request of either party, the
CPR shall appoint the mediator. The parties shall attempt to resolve the dispute through mediation
until one of the following occurs: (i) the parties reach a written settlement; (ii) the mediator
notifies the parties in writing that they have reached an impasse; (iii) the parties agree in
writing that they have reached an impasse; or (iv) the parties have not reached a settlement within
one hundred and twenty (120) days after the Notice Date.




          (c) Trial Without Jury. If the parties fail to resolve the dispute through mediation, or if
neither party elects to initiate mediation, each party shall have the right to pursue any other
remedies legally available to resolve the dispute, provided, however, that the parties expressly
waive any right to a jury trial in any legal proceeding under this Section.




     9.3. Preservation of Rights Pending Resolution.



          (a) Performance to Continue. Each party shall continue to perform its obligations under this
Agreement pending final resolution of any dispute arising out or relating to this Agreement;
provided, however, that a party may suspend performance of its obligations during any period in
which the other party fails or refuses to perform its obligations.




          (b) Provisional Remedies. Although the procedures specified in this Article are the sole and
exclusive procedures for the resolution of disputes arising out of relating to this Agreement,
either party may seek a preliminary injunction or other provisional equitable relief if, in its
reasonable judgment, such action is necessary to avoid irreparable harm to itself or to preserve
its rights under this Agreement.




          (c) Statute of Limitations. The parties agree that all applicable statutes of limitation and
time-based defenses (such as estoppel and laches) shall be tolled while the procedures set forth in
Subsections 9.2.(a) and 9.2(b) are pending. The parties shall take any actions necessary to
effectuate this result.

or unenforceable for any reason, such invalidity or unenforceability shall not affect any other
provision of this Agreement, and the parties shall negotiate in good faith to modify the Agreement
to preserve (to the extent possible) their original intent. If the parties fail to reach a
modified agreement within sixty (60) days after the relevant provision is held invalid or

TO

EXCLUSIVE LICENSE AGREEMENT

(UMMC 03-17)




     This Amendment No. 2, dated as of February  1, 2004 (the “Amendment”) is being made to the
Exclusive License Agreement relating to UMMC 03-17 (the “License Agreement”), effective as of April
15, 2003, and as amended by Amendment No. 1, effective as of October 30, 2003, by and between the

education of the Commonwealth of Massachusetts having an address of 55 Lake Avenue North,

11726 San Vicente Boulevard, Suite 650, Los Angeles, California 90049.



R E C I T A L S




     WHEREAS, Section 4.8 of the License Agreement provided for the calculation of payments payable
to Medical School under Section 4.5 and Section 4.7 of the License Agreement in the event Company
was required to make certain other payments to Medical School or third parties; and



     WHEREAS, Medical School and Company wish to clarify the manner in which Section 4.8 of the
License Agreement shall operate;



     NOW, THEREFORE, Medical School and Company hereby agree as follows:



1. Amendment to Section 4.8.




     Section 4.8 of the License Agreement is hereby amended to read in full as follows:



     “4.8 Third-Party and Other Payments. If Company is legally required to make royalty
or sublicense income payments to Medical School under any other license agreement, as well as this
Agreement, or to one or more third parties, as well as this Agreement, in the same Royalty Period
for which payments are due under Section 4.5 or 4.7 in order for Company to make, use or sell
Licensed Products or have its Sublicensee make, use, or sell Licensed Products:



          (a) Other Medical School Payments. In the case of payments to Medical School under
Sections 4.5 and 4.7 with respect to any Licensed Product, Company shall pay only the highest rate
among this Agreement and any other Medical School licenses, and that one payment shall be deemed to
satisfy the payment requirements for the applicable period under not only this Agreement but each
of the other Medical School licenses.




          (b) Third Party Payments. In the case of payments to one or more third parties with
respect to any Licensed Product under this Agreement, Company may reduce its payment to Medical
School under Section 4.5 or 4.7 of this Agreement for the applicable Royalty Period by fifty
percent
(50%) of the amount actually paid to third parties. However, in no event will the reductions
made




 









 







pursuant to this Section 4.8(b) result in more than a fifty percent (50%) reduction in the
payments that would otherwise be payable to Medical School under Section 4.5 and 4.7 (after taking
into account Section 4.8(a)).




          (c) Example: Royalty Reductions. By way of illustration for Section 4.5 royalty
payment reductions, for a particular Licensed Product, assume a royalty of (***) of Net Sales under
another Medical School license and a payment of (***) of Net Sales to a third party. The reduction
calculation would be as follows: The total (***) royalty rate in this Agreement would apply, and
Company would reduce that rate by 50% of the (***) due to the third party, resulting in a (***)
royalty to Medical School under this Agreement, and no royalties payable to the Medical School
under the other Medical School license.




          (d) Example: Sublicense Income Payments. By way of illustration for Section 4.7
Sublicense Income payment reductions, assume (i) the total Sublicense Income received by Company
from the Sublicensee is (***), and (ii) Company paid a third party (***) in order to allow the
sublicensee to make Licensed Products. Company would then be required to pay the Medical School
under this Agreement (***) (Medical School receiving (***) of the (***) reduced by one-half of the
(***) paid to the third party). If Company also sublicensed another Medical School license with
respect to the Licensed Products, Company would not be required to make additional sublicense
income payments.”
