shall be regarded as Apollo’s Confidential Information (as
defined below) and, notwithstanding Section 5.5 below, VistaGen hereby covenants that it

for any purpose other than determining whether Apollo, its
Affiliates and Sublicensees have complied with their obligations
under this Agreement; provided that VistaGen may disclose such
reports to UHN solely to use for the same purpose. VistaGen further
agrees that, notwithstanding Section 5.5 below, until such time as such information

information of similar nature and in any event not less than with a
reasonable degree of care.





5.5           Confidentiality.





(a)          Confidential
Information; Exceptions. Except to the extent expressly
authorized by this Agreement or otherwise agreed in writing, during
the Term and for a period of [*****] thereafter, the Parties hereby
agree to hold in strict confidence and not publish, disclose or
transfer, directly or indirectly, or use for any purpose other than
as provided for in this Agreement any information and materials
furnished to it by or on behalf of the other Party or its
Affiliates or generated pursuant to this Agreement (collectively,
“Confidential

of a Party or its Affiliates will include, without limitation, all
information and materials disclosed by such Party or its Affiliates
or their respective designees that (a) is marked as
“Confidential,” “Proprietary” or with
similar designation at the time of disclosure or (b) by its
nature can reasonably be expected to be considered Confidential
Information by the recipient. Information disclosed orally will not
be required to be identified as such to be considered Confidential
Information. The terms of this Agreement shall be deemed to be the
Confidential Information of both Parties. Notwithstanding the
foregoing, Confidential Information will not include any
information to the extent that it can be established by written
documentation by the receiving Party that such information: (a) was

the time of disclosure, (b) was generally available to the public
or otherwise part of the public domain at the time of its
disclosure to the receiving Party, (c) became generally available
to the public or otherwise part of the public domain after its
disclosure and other than through any act or omission of the

developed by the receiving Party as demonstrated by written
documentation prepared contemporaneously with such independent
development; or (e) was disclosed to the receiving Party, other
than under an obligation of confidentiality (except to the extent
such obligation has expired or an exception is applicable under the
relevant agreement pursuant to which such obligation was
established), by a third party who had no obligation to the
disclosing Party not to disclose such information to
others.





(b) Authorized Disclosure. Except as
expressly provided otherwise in this Agreement, each Party may use
and disclose Confidential Information of the other Party solely as
follows: (a) under appropriate confidentiality provisions
substantially equivalent to those in this Agreement: (i) in
connection with the performance of its obligations or as reasonably
necessary or useful in the exercise of its rights under this
Agreement, including the right to grant licenses or sublicenses as
permitted hereunder, or (ii) to actual or potential
bona fide (sub)licensees,
acquirers or assignees, collaborators, investment bankers,
investors or lenders with whom a Party (or its Affiliates) has
entered into good faith negotiations regarding a proposed
transaction, or; (b) to the extent such disclosure is to a
governmental authority as reasonably necessary in filing or
prosecuting the UHN Patent Rights or Present Improvement Patent
Rights, copyright and trademark applications in accordance with
this Agreement, prosecuting or defending litigation related to this
Agreement, complying with applicable governmental regulations with
respect to performance under this Agreement, obtaining Regulatory
Approval or fulfilling post-approval regulatory obligations for the
Licensed Products, or otherwise required by applicable law;
provided, however, that if
a Party is required by applicable law or the rules of any
securities exchange or automated quotation system to make any such
disclosure of the other Party’s Confidential Information it
will, except where impracticable for necessary disclosures (for
example, in the event of medical emergency), give reasonable
advance notice to the other Party of such disclosure requirement
and, in each of the foregoing, will use its reasonable efforts to
secure confidential treatment of such Confidential Information
required to be disclosed and will only disclosed that Confidential
Information that is required to be disclosed; (c) to advisors
(including lawyers and accountants) on a need to know basis, in
each case under appropriate confidentiality provisions or
professional standards of confidentiality substantially equivalent
to those of this Agreement, or (d) to the extent mutually
agreed to by the Parties. Each Party acknowledges and agrees that
the other Party may submit this Agreement to the SEC and if a Party
does submit this Agreement to the SEC, such Party agrees to consult
with the other Party with respect to the preparation and submission
of, a confidential treatment request for this Agreement. If a Party
is required by applicable law to make a disclosure of the terms of
this Agreement in a filing with or other submission to the SEC, and
[*****], then such Party will
have the right to make such public disclosure at the time and in
the manner reasonably determined by its counsel to be required by
applicable law. Notwithstanding anything to the contrary herein, it
is hereby understood and agreed that if a Party seeking to make a
disclosure to the SEC as set forth in this Section 5.5(b), [*****] such comments, limit disclosure or
obtain confidential treatment to the extent reasonably requested by
the other Party.





(c)          Press
Releases. Neither Party may issue any press release or make
any other public announcement or statement concerning this
Agreement, the transactions contemplated hereby or the terms
hereof, without the prior written approval of the other Party,
except as may be required by applicable law. In the event either Party (the
“Issuing
Party”) desires to issue
a press release or other public statement disclosing information
relating to this Agreement, the
transactions contemplated hereby or the terms hereof, the Issuing
Party will provide the other Party (the “Reviewing
Party”) with a copy of
the proposed press release or public statement (the
“Release”)
and seek the Reviewing Party’s prior written
consent. The Issuing Party will
specify with each such Release, taking into account the urgency of
the matter being disclosed, a reasonable period of time within
which the Receiving Party may provide any comments on such
Release and if the Receiving Party fails to provide any
comments during the response period called for by the Issuing
Party, the Reviewing Party will be deemed to have consented to the
issuance of such Release. If the
Receiving Party provides any comments, the Parties will consult on
such Release and work in good faith to prepare a mutually
acceptable Release. Either Party may subsequently publicly disclose
any information previously contained in any Release so consented
to.

PATENT
PROSECUTION





6.1           Responsibility
for UHN Patent Rights . Pursuant to each
License Agreement, VistaGen has the right to control the
preparation, filing, prosecution, defense in post-grant or
post-issuance administrative proceedings, and maintenance of all
patents and patent applications in respect of the UHN Patent Rights
in the Territory. VistaGen hereby grants to Apollo the sole and
exclusive right to exercise all of its rights regarding patent
prosecution, maintenance and enforcement under each License
Agreement, and VistaGen hereby appoints Apollo to act as its agent,
to prepare, file, prosecute, maintain and defend in all agency
proceedings (e.g., reissues, reexaminations, oppositions and
interferences) all of the UHN Patent Rights during the Term.
Likewise, VistaGen hereby grants to Apollo the sole and exclusive
right to prepare, file, prosecute, maintain and defend in all
agency proceedings (e.g., reissues, reexaminations, oppositions and
interferences) any and all patent rights within the Present
Improvements (the “Present Improvement Patent
Rights” and together with Future Improvement Patent
Rights, “Improvement
Patent Rights”) during the Term. With respect to the
foregoing, Apollo shall copy VistaGen on all patent prosecution
documents and give VistaGen reasonable opportunities to advise
Apollo on such filing, prosecution and maintenance. In the event
Apollo desires to abandon any patent or patent application within
the UHN Patent Rights or Present Improvement Patent Rights, Apollo
shall provide VistaGen with reasonable prior written notice of such
intended abandonment or decline of responsibility. If VistaGen
elects to continue such patent or patent application, the Parties
shall consult and Apollo may elect to retain responsibility
therefor. Otherwise, the right to prepare, file, prosecute,
maintain and defend the relevant UHN Patent Rights or Present
Improvement Patent Rights, at VistaGen’s expense, shall
revert to VistaGen and with respect to the UHN Patent Rights shall
be subject to the terms and conditions of the applicable License
Agreement.





6.2           Payment
of Expenses . The Parties
acknowledge and agree that pursuant to each License Agreement,
payment of all fees and costs, including, without limitation,
attorney’s fees, for the filing, prosecution and maintenance
of the UHN Patent Rights incurred by UHN before the Effective Date
shall be the responsibility of VistaGen. Apollo shall be
responsible for all such fees and costs incurred after the
Effective Date. For the avoidance of doubt, Apollo shall not be
responsible for payment of any fees and costs associated with the
prosecution and maintenance of the UHN Patent Rights or Present
Improvement Patent Rights incurred prior to the Effective
Date.





6.3           Patent
Extensions and Orange or Purple Book
Listings . If elections with
respect to obtaining patent term extensions (including, without
limitation, any available pediatric extensions) or supplemental
protection certificates or their equivalents in any country with
respect to UHN Patent Rights or Present Improvement Patent Rights
are available, Apollo shall have the sole and exclusive right to
make any such elections based on Licensed Products. With respect to
data exclusivity periods (such as those periods listed in the
FDA’s Orange or Purple Book (including, without limitation,
any available pediatric extensions) or periods under national
implementations of Article 10.1(a)(iii) of
Directive 2001/EC/83 or orphan exclusivity periods, and all
equivalents in any country), Apollo shall have the sole and
exclusive right to seek and maintain all such data exclusivity
periods available for the Licensed Products. With respect to all of
the rights and activities identified in this Section 6.3, VistaGen hereby appoints Apollo as its
agent for such purposes with the authority to act on
VistaGen’s behalf with respect to the UHN Patent Rights or
Present Improvement Patent Rights in a manner consistent with this
Agreement.

ARTICLE 7





INFRINGEMENT





7.1           Notification
of Infringement of Licensed IP or
Improvements . Each Party agrees
to provide written notice to the other Party promptly after
becoming aware of any infringement of the Licensed IP or
Improvements by a third party and of any available evidence
thereof, including to the extent VistaGen receives notice from UHN
of any infringement of the Licensed IP by a third party and of any
available evidence thereof.





7.2           Right
to Prosecute Infringements . Pursuant to each
License Agreement, VistaGen has the right to determine the
appropriate course of action to enforce the Licensed IP or
otherwise abate the infringement thereof, to take (or refrain from
taking) appropriate action to enforce the Licensed IP, to defend
any declaratory judgments seeking to invalidate or hold the
Licensed IP unenforceable, to control any litigation or other
enforcement action and to enter into, or permit, the settlement of
any such litigation, declaratory judgments or other enforcement
action with respect to Licensed IP.





(a)          Apollo
Right to Prosecute. VistaGen hereby assigns to Apollo the
first and exclusive right, but not the obligation, under its own
control and at its own expense, to prosecute any third party
infringement of the Licensed IP or Present Improvements, subject to
Sections 7.4 and 7.5. The total cost of any such infringement
action commenced or defended solely by Apollo shall be borne by
Apollo.





(b)          VistaGen
Right to Prosecute. If within [*****] after having been notified of any
alleged infringement that is material and competitive in the
marketplace Apollo is unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be
diligently prosecuting an infringement action, then VistaGen shall
have the right, but shall not be obligated, under its own control
and at its own expense, to prosecute any infringement of the
Licensed IP or Present Improvements, and, with respect to the
Licensed IP, the terms and conditions of the applicable License
Agreement shall govern.





7.3           Declaratory
Judgment Actions . If a declaratory
judgment action is brought naming UHN, VistaGen or Apollo or any of
its Affiliates or Sublicensees as a defendant and alleging
invalidity, unenforceability or non-infringement of any UHN Patent
Rights or Improvement Patent Rights, Apollo or VistaGen, as the
case may be, shall promptly notify the other Party in writing and
Apollo may elect, upon written notice to VistaGen within
[*****] after receiving or
giving notice of the commencement of such action, to take over the
sole control of such action at its own expense solely with respect
to UHN Patent Rights or Present Improvement Patent Rights. If
Apollo does not defend any such action, then VistaGen shall have
the right, but shall not be obligated, to defend such action at
VistaGen’s expense and, with respect to the UHN Patent
Rights, the terms of the applicable License Agreement shall
govern.





7.4           Offsets .
Apollo may offset a total of [*****] of any expenses incurred under
Sections 7.2 and 7.3 against any payments due to VistaGen under
Article 4, provided that in no event
shall such payments under Article 4,
when aggregated with any other offsets and credits allowed under
this Agreement, be reduced by more than [*****] in any Reporting
Period.





7.5           Recovery .
In the event that either Party exercises the rights conferred in
this Article 7 and recovers any
damages or other sums in such action, such damages or other sums
recovered shall first be applied to all out-of-pocket costs and
expenses incurred by the Parties in connection therewith
(including, without limitation, attorneys’ fees). If such
recovery is insufficient to cover all such costs and expenses of
both Parties, the controlling Party’s costs shall be paid in
full first before any of the other Party’s costs. If after
such reimbursement any funds shall remain from such damages or
other sums recovered, such funds shall be retained by the Party
that controlled the action or proceeding under this Article 7; provided, however, that (a) if
Apollo is the Party that controlled such action or proceeding,
VistaGen shall receive out of any such remaining recovery received
by Apollo an amount equal to royalties payable hereunder by
treating such remaining recovery as “Net Sales”
hereunder and (b) if VistaGen is the Party that controlled
such action or proceeding, the remaining recovery received by
VistaGen shall be shared equally between Apollo and
VistaGen.





7.6           Cooperation .
Each Party agrees to cooperate in any action under this Article 7 which is controlled by the other
Party, including, without limitation, joining such action as a
party plaintiff if necessary or desirable for initiation or
continuation of such action; provided that the controlling Party
reimburses the cooperating Party promptly for any reasonable costs
and expenses incurred by the cooperating Party in connection with
providing such assistance.

(e)          as
of the Effective Date, to its knowledge, there are no actions,

9.4           Limitation
of Liability. EXCEPT FOR [*****], IN NO EVENT SHALL EITHER PARTY BE
LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, EXEMPLARY OR
CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR
LOSS OF PROFITS OR EXPECTED SAVINGS OR OTHER ECONOMIC LOSSES)
ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ITS SUBJECT
MATTER. EACH PARTY’S AGGREGATE LIABILITY, IF ANY, FOR ALL
DAMAGES OF ANY KIND RELATING TO THIS AGREEMENT OR ITS SUBJECT
MATTER SHALL NOT EXCEED THE AMOUNT PAID BY APOLLO TO VISTAGEN UNDER
THIS AGREEMENT. THE FOREGOING EXCLUSIONS AND LIMITATIONS SHALL
APPLY TO ALL CLAIMS AND ACTIONS OF ANY KIND AND ON ANY THEORY OF
LIABILITY, WHETHER BASED ON CONTRACT, TORT (INCLUDING, WITHOUT
LIMITATION, NEGLIGENCE OR STRICT LIABILITY), OR ANY OTHER GROUNDS,
AND REGARDLESS OF WHETHER THE PARTY HAS BEEN ADVISED OF THE

THAT EACH WARRANTY DISCLAIMER, EXCLUSION OF DAMAGES OR OTHER
LIMITATION OF LIABILITY HEREIN IS INTENDED TO BE SEVERABLE AND

9.5           Breach
by VistaGen. In the event that VistaGen commits a breach of
any License Agreement and Apollo receives notice of such breach,
within [*****] of the receipt
of any such notice of breach, subject to any cure period permitted
under the applicable License Agreement, Apollo may request to meet
with UHN and VistaGen and representatives of the Parties shall meet
and discuss in good faith a potential cure of such breach in
accordance with the terms of the applicable License Agreement. In
the event VistaGen is unable to cure such breach, VistaGen hereby
provides Apollo (or any of its Affiliates or Sublicensees) the
right, but not the obligation, to cure such breach directly with
UHN on VistaGen’s behalf in accordance with the terms of the
applicable License Agreement. VistaGen shall reimburse Apollo (or
any of its Affiliates or Sublicensees) for any and all costs and
expenses incurred in attempting to cure, or curing, such breach. In
the event such breach is unable to be cured or is not cured
(including because Apollo does not elect to cure such breach), at
Apollo’s request, VistaGen shall use all reasonable efforts
to assist Apollo in entering into a direct license with UHN equal
in scope to the sublicense set forth in Article 2, [*****]. VistaGen further agrees not to
impede, restrict or otherwise interfere with the entrance of Apollo
and UHN into such direct license.





9.6           Breach
by UHN. In the event that UHN commits a material breach of
any License Agreement and such License Agreement is terminated as a
result of such breach, VistaGen shall delegate to Apollo, or pursue
at Apollo’s written request and expense, any cause of action
that VistaGen may have pursuant to the terms of the applicable
License Agreement.





ARTICLE 10





ASSIGNMENT





This
Agreement, and the rights and obligations hereunder, may not be
assigned or transferred, in whole or in part, by either Party
without the prior written consent of the other Party, except that
no consent shall be required for either Party to assign this
Agreement to (i) any entity acquiring it or all or substantially
all of the assets of such Party as to which this Agreement relates
whether by sale, merger, operation of law or otherwise (including,
for clarity, with respect to VistaGen all of the License
Agreements), or (ii) any of its Affiliates; provided that upon any
such assignment with respect to VistaGen, VistaGen shall similarly
assign each License Agreement and that certain letter agreement by
and among UHN, Apollo and VistaGen effective as of the date hereof
(the “Letter
Agreement”) such that the VistaGen contracting party
in each License Agreement and the Letter Agreement is the same
VistaGen contracting party as in this Agreement. Each Party shall
notify the other Party no later than [*****] after any assignment
of this Agreement. Any assignment in circumvention of the foregoing
shall be void. Subject to the foregoing, this Agreement shall be
binding upon and inure to the benefit of the Parties hereto and
their respective permitted successors and assigns.

ARTICLE 11





GENERAL
COMPLIANCE WITH LAW





11.1           Compliance
with Laws . Apollo shall use
reasonable commercial efforts to comply with all commercially
material local, state, federal, and international laws and
regulations relating to the development, manufacture, use, and sale
of Licensed Products.





11.2           Export
Control . Apollo 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. Apollo hereby gives
written assurance that it shall comply with, and shall 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 shall
indemnify, defend, and hold VistaGen harmless (in accordance with
Section 8.1) for the consequences of
any such violation.





11.3           Marking
of Licensed Products . To the extent
commercially feasible and consistent with prevailing business
practices, Apollo shall mark, and shall cause its Affiliates and
Sublicensees to mark, all Licensed Products that are manufactured
or sold under this Agreement with the number of each issued patent
under the UHN Patent Rights or Improvement Patent Rights that
applies to such Licensed Product.





ARTICLE 12





TERMINATION





12.1           Term.
Unless earlier terminated in accordance with the provisions of this
Article 12, this Agreement shall
continue in force on a country-by-country and Licensed
Product-by-Licensed Product basis until the expiration of the last
to expire patent within the UHN Patent Rights or Improvement Patent
Rights (the “Term”). Following the end
of the Term for any such Licensed Product in such country by
expiration (but not termination), the licenses granted to Apollo
under Sections 2.1(a)-(c) will become perpetual, irrevocable,
non-terminable, fully paid-up and royalty-free.





12.2           Voluntary
Termination by Apollo .





(a)          Apollo
shall have the right to terminate this Agreement, for any reason,
upon at least [*****] prior
written notice to VistaGen, such notice to state the date at least
[*****] in the future upon
which termination is to be effective.





(b)          Apollo
shall have the right to terminate this Agreement immediately upon
written notice to VistaGen on a Licensed IP-by-Licensed IP, UHN
Patent Right-by-UHN Patent Right, Improvement-by-Improvement or
Improvement Patent Right-by-Improvement Patent Right basis, such
notice to state the Licensed IP, UHN Patent Right, Improvement or
Improvement Patent Right for which such termination shall be
applicable (such terminated patent right or other intellectual
property, the “Terminated IP”). In the
event Apollo provides such notice, the Terminated IP will no longer
be subject to this Agreement, all licenses or sublicenses to such
Terminated IP will terminate and Apollo shall have no further
rights or obligations with respect to such Terminated IP as of the
date of VistaGen’s receipt of such written
notice.





12.3           Termination
for Breach .





(a)          In
the event Apollo commits a material breach of its obligations under
this Agreement, and fails to cure that breach within [*****] after receiving written notice
thereof, VistaGen may terminate this Agreement immediately upon
written notice to Apollo, subject to completion of the dispute
resolution process set forth in Article
13 and subsequent cure. Notwithstanding the foregoing, if
VistaGen terminates this Agreement due to Apollo’s failure to
timely pay the sublicense and license issue fee required in Section
4.1(a), the termination is effective upon notice and the dispute
resolution process set forth in Article 13 shall not apply to such
termination.

  Exclusive License and Sublicense Agreement


(b)          In
the event VistaGen commits a material breach of its obligations
under this Agreement, Apollo may, in its discretion, either (i)
terminate this Agreement if VistaGen has not cured such breach
within [*****] after receipt
of written notice thereof or (ii) continue this Agreement and seek
arbitration pursuant to Article 13
confirming that such breach has in fact occurred and/or seeking
specific performance, and if such arbitration finds that such
breach indeed has occurred, then any future payments to VistaGen
pursuant to Article 4 of this
Agreement shall be reduced by [*****] as of the termination
date.





12.4           Other
Grounds for Bankruptcy. A Party may terminate this Agreement
immediately if the other Party hereto is declared insolvent or
commits an act of bankruptcy.





12.5           Effect
of Expiration or Termination .





(a)          Survival.
The following provisions shall survive the expiration or
termination of this Agreement: Article
1, Article 8, Article 9, Article
13 and Article 14, and
Sections 4.1(f), 5.2 (but only with respect to obligation to
provide final report and payment), 5.3, 11.1,
11.2, 12.1 (but only with respect to the second
sentence) and 12.5.





(b)          Inventory.
Upon the early termination of this Agreement, Apollo 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 (i) Apollo
pays VistaGen the applicable running royalty or other amounts due
on Net Sales of any Revenue Bearing Products in accordance with the
terms and conditions of this Agreement, and (ii) Apollo and
its Affiliates and Sublicensees shall complete and sell all
work-in-progress and inventory of Licensed Products after the
effective date of termination.





(c)          Expiration
or termination of this Agreement for any reason shall not relieve
either Party of any liability or obligation which accrued hereunder
prior to the effective date of such termination or
expiration.





ARTICLE 13





DISPUTE RESOLUTION





13.1           Mandatory
Procedures . 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 13, and that such procedures
constitute legally binding obligations that are an essential
provision of this Agreement. If either Party fails to observe the
procedures of this Article 13, as may
be modified by their written agreement, the other Party may bring
an action for specific performance of these procedures in any court
of competent jurisdiction.





13.2           Equitable
Remedies . Although the
procedures specified in this Article
13 are the sole and exclusive procedures for the resolution of
disputes arising out of or 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.





13.3           Dispute
Resolution Procedures . Any controversy
or claim arising out of or relating to this Agreement, or the
breach thereof, shall be settled by binding confidential
arbitration in accordance with the Commercial Arbitration Rules
(the “Rules”) of the American
Arbitration Association (“AAA”), and the procedures
set forth below. In the event of any inconsistency between the
Rules of AAA and the procedures set forth below, the procedures set
forth below shall control. Judgment upon the award rendered by the
arbitrators may be enforced in any court having jurisdiction
thereof.





(a)          The
location of the arbitration shall be in the County of New York.
VistaGen and Apollo hereby irrevocably submit to the exclusive
jurisdiction and venue of the AAA arbitration panel selected by the
Parties and located in New York, New York for any dispute regarding
this Agreement, and to the exclusive jurisdiction and venue of the
federal and state courts located in New York, New York for any
action or proceeding to enforce an arbitration award or as
otherwise provided in Section 13.3(e), and
waive any right to contest or otherwise object to such jurisdiction
or venue.

 -21-
  Exclusive License and Sublicense Agreement


(b)          The
arbitration shall be conducted by a panel of three neutral
arbitrators who are independent and disinterested with respect to
the Parties, this Agreement, and the outcome of the arbitration.
Each Party shall appoint one neutral arbitrator, and these two
arbitrators so selected by the Parties shall then select the third
arbitrator, and all arbitrators must have at least ten (10)
years’ experience in mediating or arbitrating cases regarding
the same or substantially similar subject matter as the dispute
between VistaGen and Apollo. If one Party has given written notice
to the other Party as to the identity of the arbitrator appointed
by the Party, and the Party thereafter makes a written demand on
the other Party to appoint its designated arbitrator within the
next ten days, and the other Party fails to appoint its designated
arbitrator within ten days after receiving said written demand,
then the arbitrator who has already been designated shall appoint
the other two arbitrators.





(c)          The
arbitrators shall decide any disputes and shall control the process
concerning these pre-hearing discovery matters. Pursuant to the
Rules of AAA, the Parties may subpoena witnesses and documents for
presentation at the hearing.





(d)          Prompt
resolution of any dispute is important to both Parties; and the
Parties agree that the arbitration of any dispute shall be
conducted expeditiously. The arbitrators are instructed and
directed to assume case management initiative and control over the
arbitration process (including, without limitation, scheduling of
events, pre-hearing discovery and activities, and the conduct of
the hearing), in order to complete the arbitration as expeditiously
as is reasonably practical for obtaining a just resolution of the
dispute.





(e)          The
arbitrators may grant any legal or equitable remedy or relief that
the arbitrators deem just and equitable, to the same extent that
remedies or relief could be granted by a state or federal court,
provided however, that no punitive damages may be awarded. No court
action shall be maintained seeking punitive damages. The decision
of any two of the three arbitrators appointed shall be binding upon
the Parties. Notwithstanding anything to the contrary in this
Agreement, prior to or while an arbitration proceeding is pending,
either Party has the right to seek and obtain injunctive and other
equitable relief from a court of competent jurisdiction to enforce
that Party’s rights hereunder.





(f)          The
expenses of the arbitration, including, without limitation, the
arbitrators’ fees, expert witness fees, and attorney’s
fees, may be awarded to the prevailing Party, in the discretion of
the arbitrators, or may be apportioned between the Parties in any
manner deemed appropriate by the arbitrators. Unless and until the
arbitrators decide that one Party is to pay for all (or a share) of
such expenses, both Parties shall share equally in the payment of
the arbitrators’ fees as and when billed by the
arbitrators.





(g)          Notwithstanding
the foregoing, any disputes arising hereunder with respect to the
inventorship, validity, enforceability or other aspect of
intellectual property rights shall be resolved by a court of
competent jurisdiction and not by arbitration.





(h)          Except
as set forth below and as necessary to obtain or enforce a judgment
upon any arbitration award, the Parties shall keep confidential the
fact of the arbitration, the dispute being arbitrated, and the
decision of the arbitrators. Notwithstanding the foregoing, the
Parties may disclose information about the arbitration to persons
who have a need to know, such as directors, trustees, management
employees, witnesses, experts, investors, attorneys, lenders,
insurers, actual or potential collaborators or corporate partners
of Apollo, actual or potential acquirors of Apollo, and others who
may be directly affected provided that such persons are bound to
keep such information confidential. Additionally, if a Party has
stock which is publicly traded, the Party may make such disclosures
as are required by applicable securities laws, but shall use
commercially reasonably efforts to seek confidential treatment for
such disclosure.





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





13.5           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 Section 13.5 are pending.
The Parties shall cooperate in taking any actions necessary to
achieve this result.

4. FINANCIAL
CONSIDERATIONS





4.1     Development-Based Milestone
Payments. At such time as Licensee (or its Affiliates or
Sublicensees) achieve a Milestone Event as described below for a
specific Licensed Product, Licensee shall pay to Licensor the
Milestone Payment specified below. The specified milestone payment
shall be made within thirty (30) days after the occurrence of the
Milestone Event.





A.
 "Milestone
Event" for Therapeutic-Related Licensed
Product *
"Milestone Payment"
(US$)(1)
Acceptance
by FDA (first country) of filing of IND
$150,000(2)
First
patient enrolled for Phase II Clinical Trial
$250,000(3)
First
patient enrolled for Phase HI Clinical Trial
$1,500,000(4)
FDA
(First country) Final Approval of NDA for Licensed
Product

 B.  "Milestone Event" for Service-Related
Licensed Product
"Milestone Payment"
(US$)(1)
First
anniversary of execution of an agreement in respect of (in whole or
in part) a Service-Related Licensed Product
$50,000
**





For the purpose of this Section 4.1 "Final Approval" shall mean
approval by the FDA for marketing a Therapeutic-Related Licensed
Product that is not conditioned on any other event (or if an
approval is conditioned upon an event, then the occurrence of that
event), provided, however, such other events shall specifically not
include FDA requirements to conduct post marketing studies and any
requirement for such post marketing studies shall not be deemed to
delay the Final Approval.





* Once
a Milestone Payment has been made for a specific Licensed Product,
if there are later modifications, improvements, reformulations,
combinations, or other changes using the same molecule which
constitutes said Licensed Product (i.e., a "Related Product"), then no
duplicate Milestone Payment will be owed when that Related Product
achieves the same Milestone Event for which the Milestone Payment
was previously made for said specific Licensed Product. Similarly,
if there is a failure in product development, resulting in the
substitution or replacement of the failed molecule with a new
molecule, to the extent that a Milestone Event had previously been
achieved by the failed molecule and the corresponding Milestone
Payment paid, then no duplicate Milestone Payment will be owed when
the new molecule achieves the same Milestone Event for which the
Milestone Payment was previously made for the failed
molecule.





**
But not more than 10% of the annual revenues received from said
agreement, continuing annually until the cumulative aggregate of
said 10% payments reach $50,000.

4.2  Royalties.





4.2.1   Royalty Rate. Licensee shall
pay to Licensor three percent (3%) of the first $25 million of
Revenues received by Licensee or its Affiliates, and two percent
(2%) of all additional Revenues received by Licensee or its
Affiliates, subject to reductions pursuant to Sections 4.2.2 and
4.2.3.





4.2.2Third
Party Royalties. If Licensee or its Affiliates is required
to pay royalties to any Third Party that are, in the opinion of an
independent patent attorney (reasonably acceptable to both
parties), necessary to practice the inventions claimed in the
Licensed IP, then Licensee shall have the right to credit such
Third Party royalty payments against the royalties owing to
Licensor under Section 4.2.1; provided, however, that the
foregoing credits shall not reduce the amount of the royalties
payable to Licensor under Section 4.2.1 above by more than fifty
percent (50%).





4.2.3Combination
Products. If a Product consists of (i) components that are
covered by Licensor's Valid Claims, plus (ii) additional active
pharmaceutical agents, or functional components reasonable
necessary for formulation or delivery of the Product that are not
covered by a Valid Claim, but that are covered by a valid claim of
a Third Party patent, then for purposes of the royalty payments
under Section 4.2.1, the Revenues shall be equitably allocated
between the components covered by Licensor's Valid Claim and the
components covered by the Third Party patent, with only the portion
of Revenues allocated to Licensor's Valid Claims being used for
purposes of the royalty calculation in Section 4.2.1 for such
combination Product. To the extent the parties are unable to agree
on the equitable allocation described above, any dispute shall be
resolved in accordance with Section 12.3 of this Agreement.
Notwithstanding the aforementioned, the foregoing allocation shall
not reduce the amount of the royalties payable to Licensor under
Section 4.2.1 above by more than fifty percent (50%).





5.      ROYALTY
REPORTS. PAYMENTS. AND ACCOUNTING





5.1Royalty
Reports. Within sixty (60) days after the end of each
calendar quarter during the term of this Agreement following the
receipt by Licensee or its Affiliates of Revenues, Licensee shall
furnish to Licensor a quarterly written report showing in
reasonably specific detail (a) the calculation of Revenues for such
quarter; and (b) the calculation of the royalties that shall have
accrued based upon such Revenues.





5.2Payment
Terms. Royalties shown to have accrued by each royalty
report provided for under Section 5.1 above shall be due on the
date such royalty report is due.





5.3Audits.





5.3.1   Upon the written request of Licensor and not
more than once in each calendar year, Licensee and its Affiliates
shall permit an independent certified public accounting firm of
nationally recognized standing selected by Licensor and reasonably
acceptable to Licensee, at Licensor's expense, to have access
during normal business hours to such of the financial records of
Licensee and its Affiliates as may be reasonably necessary to
verify the accuracy of the payment reports hereunder for the eight
(8) calendar quarters immediately prior to the date of such request
(other than records for which Licensor has already conducted an
audit under this Section).





5.3.2If such
accounting firm concludes that additional amounts were owed during
the audited period, Licensee shall pay such additional amounts
within thirty (30) days after the date Licensor delivers to
Licensee such accounting firm's written report so concluding. The
fees charged by such accounting firm shall be paid by Licensor;
provided, however, if the audit discloses that the royalties paid
by Licensee for such period were more than seven percent (7%) below

Confidential Information of Licensee that is disclosed to Licensor,
and shall not use, disclose or grant the use of the Confidential
Information except on a need-to-know basis to those directors,
officers, employees and agents, to the extent such disclosure is
reasonably necessary in connection with exercising its rights under
this Agreement.





7.2Terms
of this Agreement. Except as otherwise required by
applicable laws, Licensor and Licensee shall not disclose any terms
or conditions of this Agreement to any Third Party without the
prior consent of the other Party. Notwithstanding the foregoing,

to control, at its sole cost, the preparation, filing, prosecution,
defense in post-grant and/or post-issuance administrative

  Exclusive License and Sublicense Agreement





8.2Notification
of Infringement, Each Party shall notify the other Party of
any substantial infringement known to such Party of any Licensed
Patents and shall provide the other Party with the available
evidence, if any, of such infringement.





8.3Enforcement
of Patent Rights. Licensee, at its sole expense, shall have
the right to determine the appropriate course of action to enforce
Licensed Patents or otherwise abate the infringement thereof,
to take (or refrain from taking) appropriate action to enforce
Licensed Patents, to defend any declaratory judgments seeking to
invalidate or hold the Licensed Patents unenforceable, to control
any litigation or other enforcement action and to enter into, or
permit, the settlement of any such litigation, declaratory
judgments or other enforcement action with respect to Licensed
Patents, in each case in Licensee's own name and, if necessary for
standing purposes, in the name of Licensor and shall consider, in
good faith, the interests of Licensor in so doing. If Licensee does
not, within six (6) months after receipt of notice from Licensor,
abate the infringement or file suit to enforce the Licensed Patents
against at least one infringing Party, Licensor shall have the
right to take whatever action it deems appropriate to enforce the
Licensed Patents; provided, however, that, within thirty (30) days
after receipt of notice of Licensor's intent to file such suit,
Licensee shall have the right to jointly prosecute such suit and to
fund up toone-halfthe costs of such suit. The Party
controlling any such joint enforcement action shall not settle the
action or otherwise consent to an adverse judgment in such joint
action that diminishes the rights or interests of the
non-controlling Party without the prior written consent of the
other Party. All monies recovered upon the final judgment or
settlement of any such suit to enforce the Licensed Patents shall
be shared in relation to the damages (including attorneys' fees and
expenses for the enforcement action) incurred by each Party as a
result of such infringement; and such recovery shall not be treated
as Revenues for purposes of Section 4.2.1. Notwithstanding the
foregoing, to the extent any part of the recovery includes a
reasonable royalty payable to Licensee, such royalty amounts shall
be deemed Revenue on which Licensee will pay a royalty to Licensor
in accordance with Section 4.2.1.





8.4    Cooperation. In any suit to
enforce and/or defend the Licensed Patents pursuant to this Section
8, the Party not in control of such suit shall, at the request and
expense of the controlling Party, reasonably cooperate and, to the
extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples,
specimens, and the like.





9. TERMINATION





9.1Expiration.
Subject to Sections 9.3 and 9.4 below, this Agreement shall expire
on the expiration of Licensee's obligation to make payments to
Licensor under Section 4 above. The license grant under Section 3.1
shall be effective at all times prior to such
expiration.





9.2Termination
by Mutual Consent. The Parties may terminate this Agreement
at any time by mutual consent, which consent shall be evidenced by
a written agreement or other such documentation duly executed by
both Parties.





9.3Termination
by Licensee. Licensee may terminate this Agreement, in its
sole discretion, upon thirty (30) days prior written notice to
Licensor, provided, however, Licensee shall remain liable for any
payments accrued under this Agreement prior to the date of
termination.





9.4Termination
for Cause. Except as otherwise provided in Section 11,
Licensor may terminate this Agreement upon or after the breach of
any material provision of this Agreement by Licensee, if Licensee
has not cured such breach within ninety (90) days after receipt of
express written notice thereof by Licensor; provided, however, if
any default is not capable of being cured within such ninety (90)
day period and Licensee is diligently undertaking to cure such
default as soon as commercially feasible thereafter under the
circumstances, Licensor shall have no right to terminate this
Agreement.





9.5Termination
Upon Licensee Insolvency. This Agreement shall terminate at least
one day prior to the occurrence of any of the following events: (i)
the Licensee files a voluntary petition in bankruptcy or insolvency
or shall petition for reorganization under the bankruptcy law, or
makes a general assignment for the benefit of creditors, or
otherwise acknowledges insolvency or is adjudged bankrupt; (ii) the
Licensee consents to an involuntary petition in bankruptcy or if a
receiving order is given against it under any applicable
bankruptcy/insolvency law in a jurisdiction; (iii) the appointment
of a receiver or other similar representative for the Licensee by a
court of competent jurisdiction; or (iv) Licensee fails to carry on
business in the normal course.





9.6Effect
of Expiration or Termination. Expiration or termination of
this Agreement shall not relieve the Parties of any obligation
accruing prior to such expiration or termination, and the
provisions of Sections 1, 2, 5,7, 9.1, 9.6,10 and 12 shall survive
the expiration or termination of this Agreement. Upon any
termination of this Agreement, Licensor shall grant a direct
license to any sublicense of Licensee hereunder having the same
scope as such sublicense and on terms and conditions no less
favorable to such Sublicensee than the terms and conditions of this
Agreement, provided that such Sublicensee is not in default of any
applicable obligations under this Agreement and agrees in writing
to be bound by the terms and conditions of such direct license.
Upon any termination of this Agreement, for a period of six (6)
months thereafter, Licensee (and its Affiliates and Sublicensees)
shall continue to be entitled to finish production of any Products
which were in process at the time of termination, and Licensee (and
its Affiliates and Sublicensees) shall be entitled to sell all
Products which were in inventory or in process at the time of
termination, so long as Licensee (and its Affiliates and
Sublicensees) continues to make the reports and pay the scheduled
royalties for said sales as set forth in this
Agreement.

  Exclusive License and Sublicense Agreement





10. INDEMNIFICATION





10.1Indemnification.
Licensee shall defend, indemnify and hold Licensor (which for
purposes of clarity, is recognized to include, without limitation,
its directors, officers, employees, research trainees, students and
agents) harmless from all losses, liabilities, damages and expenses
(including attorneys' fees and costs) incurred as a result of any
claim, demand, action or proceeding arising out of any breach of
this Agreement by Licensee, any damages or personal injury
resulting from the use, application of, distribution, sale or other
exploitation of the Licensed IP, Licensed Patents and the Licensed
Product by Licensee, its Affiliates or Sublicensees, or the gross
negligence or willful misconduct of Licensee in the performance of
its obligations under this Agreement, except in each case to the
extent arising from the gross negligence or willful misconduct of
Licensor or the breach of this Agreement by Licensor.





10.2Procedure.
Licensor promptly shall notify Licensee of any liability or action
in respect of which Licensor intends to claim such indemnification,
and Licensee shall have the right to assume the defense thereof
with counsel selected by Licensee. The indemnity agreement in this
Section 10 shall not apply to amounts paid in settlement of any
loss, claim, damage, liability or action if such settlement is
effected without the consent of Licensee, which consent shall not
be withheld unreasonably. The failure to deliver notice to Licensee
within a reasonable time after the commencement of any such action,
if prejudicial to its ability to defend such action, shall relieve
Licensee of any liability to Licensor under this Section 10, but
the omission so to deliver notice to Licensee will not relieve it
of any liability that it may have to Licensor otherwise than under
this Section 10. Licensor under this Section 10, its employees and
agents, shall cooperate fully with Licensee and its legal
representatives in the investigation and defense of any action,
claim or liability covered by this indemnification.





10.3         Insurance.
During the term of this Agreement, Licensee shall maintain
at its own expense:





10.3.1Comprehensive
general liability insurance for claims for damages arising from
bodily injury (including death) and property damages caused by, or
arising out of, acts or omissions of its employees, in such amounts
as are customary and reasonable in the Licensee's
industry.





10.3.2Product
liability insurance in such amounts as are customary and reasonable
in the Licensee's industry.





10.3.3Maintenance
of such insurance coverage shall not relieve Licensee of any
responsibility under this Agreement for damage in excess of the
insurance limits.





10.4Certificates
of Insurance. Licensee shall furnish or cause to be
furnished to Licensor a certificate of such insurance promptly upon
request by Licensor. Each such certificate shall name Licensor an
additional named insured.





10.5Notice
of Cancellation or Expiration. Any such insurance
policy shall provide that the insurer will give Licensor at least
sixty (60) days prior written notice of any impending cancellation,
nonrenewal, expiration, or reduction in coverage of the
insurance.





11.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 to the extent, and for so long as, such failure or delay
is caused by or results from Force Majeure events.

purpose of this Section 4.1 "Final Approval" shall mean approval by
the FDA for marketing a Therapeutic-Related Licensed Product that
is not conditioned on any other event (or if an approval is
conditioned upon an event, then the occurrence of that event),

* Once
a Milestone Payment has been made for a specific Licensed Product,
if there are later modifications, improvements, reformulations,
combinations, or other changes using the same molecule which
constitutes said Licensed Product (i.e., a "Related Product"), then
no duplicate Milestone Payment will be owed when that Related
Product achieves the same Milestone Event for which the Milestone Payment was
previously made for said specific Licensed Product. Similarly, if
there is a failure in product development, resulting in the
substitution or replacement of the failed molecule with a new
molecule, to the extent that a Milestone Event had previously been
achieved by the failed molecule and the corresponding Milestone
Payment paid, then no duplicate Milestone Payment will be owed when
the new molecule achieves the same Milestone Event for which the
Milestone Payment was previously made for the failed
molecule.

harmless from all losses, liabilities, damages and expenses

claim, demand, action or proceeding arising out of any breach of
this Agreement by Licensee, any damages or personal injury
resulting from the use, application of, distribution, sale or other
exploitation of the Licensed IP, Licensed Patents and the Licensed

damage, liability or action if such settlement is effected without
the consent of Licensee, which consent shall not be withheld
unreasonably. The failure to deliver notice to Licensee within a
reasonable time after the commencement of any such action, if
prejudicial to its ability to defend such action, shall relieve
Licensee of any liability to Licensor under this Section 10, but

of any liability that it may have to Licensor otherwise than under
this


Section

cooperate fully with Licensee and its legal representatives in the

insurance in such amounts as are customary and reasonable in the
Licensee's industry.





10.3.3.  Maintenance of
such insurance coverage shall not relieve Licensee of any
responsibility under this Agreement for damage In excess of the
insurance limits.

4.           FINANCIAL
CONSIDERATIONS





4.1          Development-Based
Milestone Payments. At such
time as Licensee (or its Affiliates or Sublicensees) achieve a
Milestone Event as described below for a specific Licensed Product,
Licensee shall pay to Licensor the Milestone Payment specified
below. The specified milestone payment shall be made within thirty
(30) days after the occurrence of the Milestone
Event.

For the
purpose of this Section 4.1 “Final Approval” shall
mean approval by the FDA for marketing a Therapeutic-Related
Licensed Product that is not conditioned on any other event (or if
an approval is conditioned upon an event, then the occurrence of
that event), provided, however, such other events shall
specifically not include FDA requirements to conduct post marketing
studies and any requirement for such post marketing studies shall
not be deemed to delay the Final Approval.





* Once
a Milestone Payment has been made for a specific Licensed Product,
if there are later modifications, improvements, reformulations,
combinations, or other changes using the same molecule which
constitutes said Licensed Product (i.e., a “Related Product”), then
no duplicate Milestone Payment will be owed when that Related
Product achieves the same Milestone Event for which the Milestone
Payment was previously made for said specific Licensed Product.
Similarly, if there is a failure in product development, resulting
in the substitution or replacement of the failed molecule with a
new molecule, to the extent that a Milestone Event had previously
been achieved by the failed molecule and the corresponding
Milestone Payment paid, then no duplicate Milestone Payment will be
owed when the new molecule achieves the same Milestone Event for
which the Milestone Payment was previously made for the failed
molecule.





** But
not more than 10% of the annual revenues received from said
agreement, continuing annually until the cumulative aggregate of
said 10% payments reach US$50,000.

Prosecution and Maintenance. Licensee shall have the right
to control, at its sole cost, the preparation, filing, prosecution,
defense in post-grant and/or post issuance administrative
procedures, and maintenance of all patents and patent applications
in respect of Licensed Patents in the Territory and shall be solely
responsible for all prior and future costs incurred in the
preparation, filing, prosecution and maintenance of such patents
and patent applications from the Effective Date through the
termination of this Agreement. For further clarification, Licensee
shall reimburse Licensor (i) for costs incurred by UHN for the
preparation, filing, prosecution of Licensed IP prior to the
Effective Date (CAD$18,979.55 as of WS record on 6 Dec 2016),

related to the future preparation, filing, prosecution, defense in
post-grant and/or post issuance administrative procedures, and

Licensed Patents, if any, incurred by UHN at Licensee’s
request after the Effective Date. All such applications in respect
of Licensed Patents shall be filed in the name of Licensor.
Licensee shall give Licensor an opportunity to review and comment

and patent applications, and (b) Licensee shall thereafter

  Exclusive License and Sublicense Agreement





8.3          Enforcement
of Patent Rights. Licensee, at its sole expense, shall have
the right to determine the appropriate course of action to enforce
Licensed Patents or otherwise abate the infringement thereof, to
take (or refrain from taking) appropriate action to enforce
Licensed Patents, to defend any declaratory judgments seeking to
invalidate or hold the Licensed Patents unenforceable, to control
any litigation or other enforcement action and to enter into, or
permit, the settlement of any such litigation, declaratory
judgments or other enforcement action with respect to Licensed
Patents, in each case in Licensee’s own name and, if
necessary for standing purposes, in the name of Licensor and shall
consider, in good faith, the interests of Licensor in so doing. If
Licensee does not, within six (6) months after receipt of notice
from Licensor take reasonable steps to abate the infringement or
file suit to enforce the Licensed Patents against at least one
infringing Party , Licensor shall have the right to take whatever
action it deems appropriate to enforce the Licensed Patents;
provided, however, that, within thirty (30) days after receipt of
notice of Licensor’s intent to file such suit, Licensee shall
have the right to jointly prosecute such suit and to fund up to
one-half (1⁄2) the costs of such suit. The Party controlling any
such joint enforcement action shall not settle the action or
otherwise consent to an adverse judgment in such joint action that
diminishes the rights or interests of the non-controlling Party
without the prior written consent of the other Party. All monies
recovered upon the final judgment or settlement of any such suit to
enforce the Licensed Patents shall be shared in relation to the
damages (including attorneys’ fees and expenses for the
enforcement action) incurred by each Party as a result of such
infringement; and such recovery shall not be treated as Revenues
for purposes of Section 4.2.1.
Notwithstanding the foregoing, to the extent any part of the
recovery includes a reasonable royalty payable to Licensee, such
royalty amounts shall be deemed Revenue on which Licensee will pay
a royalty to Licensor in accordance with Section 4.2.1.





8.4          Cooperation.
In any suit to enforce and/or defend the Licensed Patents pursuant
to this Section 8, the Party not
in control of such suit shall, at the request and expense of the
controlling Party, reasonably cooperate and, to the extent
possible, have its employees testify when requested and make
available relevant records, papers, information, samples,
specimens, and the like.

to Licensor under Section 4
above. The license grant under Section 3.1 shall be effective at all times prior to
such expiration.





9.2          Termination
by Mutual Consent. The Parties may terminate this Agreement
at any time by mutual consent, which consent shall be evidenced by
a written agreement or other such documentation duly executed by
both Parties.

by Licensee. Licensee may terminate this Agreement, in its
sole discretion, upon thirty (30) days prior written notice to
Licensor, provided, however, Licensee shall remain liable for any
payments accrued under this Agreement prior to the date of
termination.





9.4          Termination
for Cause. Except as otherwise provided in
Section 11, Licensor may terminate
this Agreement upon or after the breach of any material provision
of this Agreement by Licensee, if Licensee has not cured such
breach within ninety (90) days after receipt of express written
notice thereof by Licensor; provided, however, if any default is
not capable of being cured within such ninety (90) day period and
Licensee is diligently undertaking to cure such default as soon as
commercially feasible thereafter under the circumstances, Licensor
shall have no right to terminate this Agreement.

9.5          Termination
Upon Licensee Insolvency. This Agreement shall terminate at
least one day prior to the occurrence of any of the following
events: (i) the Licensee files a voluntary petition in bankruptcy
or insolvency or shall petition for reorganization under the
bankruptcy law, or makes a general assignment for the benefit of
creditors, or otherwise acknowledges insolvency or is adjudged

applicable bankruptcy/insolvency law in a jurisdiction; (iii) the

Licensee by a court of competent jurisdiction; or (iv) Licensee
fails to carry on business in the normal course.





9.6          Effect
of Expiration or Termination. Expiration or termination of
this Agreement shall not relieve the Parties of any obligation
accruing prior to such expiration or termination, and the
provisions of Sections 1, 2, 5, 7, 9.1, 9.6, 10 and 12 shall
survive the expiration or termination of this Agreement. Upon any
termination of this Agreement, Licensor shall grant a direct
license to any sublicense of Licensee hereunder having the same
scope as such sublicense and on terms and conditions no less
favorable to such Sublicensee than the terms and conditions of this
Agreement, provided that such Sublicensee is not in default of any
applicable obligations under this Agreement and agrees in writing
to be bound by the terms and conditions of such direct license.
Upon any termination of this Agreement, for a period of six
(6) months thereafter, Licensee (and its Affiliates and
Sublicensees) shall continue to be entitled to finish production of
any Products which were in process at the time of termination, and
Licensee (and its Affiliates and Sublicensees) shall be entitled to
sell all Products which were in inventory or in process at the time
of termination, so long as Licensee (and its Affiliates and
Sublicensees) continues to make the reports and pay the scheduled
royalties for said sales as set forth in this
Agreement.





10.           INDEMNIFICATION





10.1          Indemnification.
Licensee shall defend, indemnify and hold Licensor (which for
purposes of clarity, is recognized to include, without limitation,
its directors, officers, employees, research trainees, students and
agents) harmless from all losses, liabilities, damages and expenses
(including attorneys’ fees and costs) incurred as a result of
any claim, demand, action or proceeding arising out of any breach
of this Agreement by Licensee, any damages or personal injury
resulting from the use, application of, distribution, sale or other
exploitation of the Licensed IP, Licensed Patents and the Licensed
Product by Licensee, its Affiliates or Sublicensees, or the gross
negligence or willful misconduct of Licensee in the performance of
its obligations under this Agreement, except in each case to the
extent arising from the gross negligence or willful misconduct of
Licensor or the breach of this Agreement by Licensor.





10.2          Procedure.
Licensor promptly shall notify Licensee of any liability or action
in respect of which Licensor intends to claim such indemnification,
and Licensee shall have the right to assume the defense thereof
with counsel selected by Licensee. The indemnity agreement in this
Section 10 shall not apply to
amounts paid in settlement of any loss, claim, damage, liability or
action if such settlement is effected without the consent of
Licensee, which consent shall not be withheld unreasonably. The
failure to deliver notice to Licensee within a reasonable time
after the commencement of any such action, if prejudicial to its
ability to defend such action, shall relieve Licensee of any
liability to Licensor under this Section 10, but the omission so to deliver notice to
Licensee will not relieve it of any liability that it may have to
Licensor otherwise than under this Section 10. Licensor under this Section 10, its employees and agents, shall cooperate
fully with Licensee and its legal representatives in the
investigation and defense of any action, claim or liability covered
by this indemnification.

is caused by or results from Force Majeure events.

of Patent Rights. Licensee, at its sole expense, shall have
the right to determine the appropriate course of action to enforce
Licensed Patents or otherwise abate the infringement thereof, to
take (or refrain from taking) appropriate action to enforce
Licensed Patents, to defend any declaratory judgments seeking to
invalidate or hold the Licensed Patents unenforceable, to control
any litigation or other enforcement action and to enter into, or
permit, the settlement of any such litigation, declaratory
judgments or other enforcement action with respect to Licensed
Patents, in each case in Licensee’s own name and, if
necessary for standing purposes, in the name of Licensor and shall
consider, in good faith, the interests of Licensor in so doing. If
Licensee does not, within six (6) months after receipt of notice
from Licensor take reasonable steps to abate the infringement or
file suit to enforce the Licensed Patents against at least one
infringing Party , Licensor shall have the right to take whatever
action it deems appropriate to enforce the Licensed Patents;
provided, however, that, within thirty (30) days after receipt of
notice of Licensor’s intent to file such suit, Licensee shall
have the right to jointly prosecute such suit and to fund up to
one-half (1⁄2) the costs of such suit. The Party controlling any
such joint enforcement action shall not settle the action or
otherwise consent to an adverse judgment in such joint action that
diminishes the rights or interests of the non-controlling Party
without the prior written consent of the other Party. All monies
recovered upon the final judgment or settlement of any such suit to
enforce the Licensed Patents shall be shared in relation to the
damages (including attorneys’ fees and expenses for the
enforcement action) incurred by each Party as a result of such
infringement; and such recovery shall not be treated as Revenues
for purposes of Section 4.2.1.
Notwithstanding the foregoing, to the extent any part of the
recovery includes a reasonable royalty payable to Licensee, such
royalty amounts shall be deemed Revenue on which Licensee will pay
a royalty to Licensor in accordance with Section 4.2.1.





8.4.  Cooperation.
In any suit to enforce and/or defend the Licensed Patents pursuant
to this Section 8, the Party not
in control of such suit shall, at the request and expense of the
controlling Party, reasonably cooperate and, to the extent
possible, have its employees testify when requested and make
available relevant records, papers, information, samples,
specimens, and the like.





9.  TERMINATION





9.1.  Expiration.
Subject to Sections 9.3 and 9.4
below, this Agreement shall expire on the expiration of
Licensee’s obligation to make payments to Licensor under
Section 4 above. The license
grant under Section 3.1 shall be
effective at all times prior to such expiration.





9.2.  Termination
by Mutual Consent. The Parties may terminate this Agreement
at any time by mutual consent, which consent shall be evidenced by
a written agreement or other such documentation duly executed by
both Parties.





9.3.  Termination by Licensee.

9.4.  Termination
for Cause. Except as otherwise provided in
Section 11, Licensor may terminate
this Agreement upon or after the breach of any material provision
of this Agreement by Licensee, if Licensee has not cured such
breach within ninety (90) days after receipt of express written
notice thereof by Licensor; provided, however, if any default is
not capable of being cured within such ninety (90) day period and
Licensee is diligently undertaking to cure such default as soon as
commercially feasible thereafter under the circumstances, Licensor
shall have no right to terminate this Agreement.





9.5.  Termination
Upon Licensee Insolvency. This Agreement shall terminate at
least one day prior to the occurrence of any of the following
events: (i) the Licensee files a voluntary petition in bankruptcy
or insolvency or shall petition for reorganization under the
bankruptcy law, or makes a general assignment for the benefit of
creditors, or otherwise acknowledges insolvency or is adjudged
bankrupt; (ii) the Licensee consents to an involuntary petition in
bankruptcy or if a receiving order is given against it under any
applicable bankruptcy/insolvency law in a jurisdiction; (iii) the
appointment of a receiver or other similar representative for the
Licensee by a court of competent jurisdiction; or (iv) Licensee
fails to carry on business in the normal course.





9.6.  Effect

this Agreement shall not relieve the Parties of any obligation
accruing prior to such expiration or termination, and the
provisions of Sections 1, 2, 5, 7, 9.1, 9.6, 10 and 12 shall
survive the expiration or termination of this Agreement. Upon any
termination of this Agreement, Licensor shall grant a direct
license to any sublicense of Licensee hereunder having the same
scope as such sublicense and on terms and conditions no less
favorable to such Sublicensee than the terms and conditions of this
Agreement, provided that such Sublicensee is not in default of any
applicable obligations under this Agreement and agrees in writing
to be bound by the terms and conditions of such direct license.
Upon any termination of this Agreement, for a period of six
(6) months thereafter, Licensee (and its Affiliates and
Sublicensees) shall continue to be entitled to finish production of
any Products which were in process at the time of termination, and
Licensee (and its Affiliates and Sublicensees) shall be entitled to

10.  INDEMNIFICATION

purposes of clarity, is recognized to include, without limitation,
its directors, officers, employees, research trainees, students and
agents) harmless from all losses, liabilities, damages and expenses
(including attorneys’ fees and costs) incurred as a result of
any claim, demand, action or proceeding arising out of any breach
of this Agreement by Licensee, any damages or personal injury
resulting from the use, application of, distribution, sale or other
exploitation of the Licensed IP, Licensed Patents and the Licensed
Product by Licensee, its Affiliates or Sublicensees, or the gross
negligence or willful misconduct of Licensee in the performance of
its obligations under this Agreement, except in each case to the
extent arising from the gross negligence or willful misconduct of
Licensor or the breach of this Agreement by Licensor.

10.2.  Procedure.
Licensor promptly shall notify Licensee of any liability or action
in respect of which Licensor intends to claim such indemnification,
and Licensee shall have the right to assume the defense thereof
with counsel selected by Licensee. The indemnity agreement in this
Section 10 shall not apply to
amounts paid in settlement of any loss, claim, damage, liability or
action if such settlement is effected without the consent of
Licensee, which consent shall not be withheld unreasonably. The
failure to deliver notice to Licensee within a reasonable time
after the commencement of any such action, if prejudicial to its
ability to defend such action, shall relieve Licensee of any
liability to Licensor under this Section 10, but the omission so to deliver notice to
Licensee will not relieve it of any liability that it may have to
Licensor otherwise than under this Section 10. Licensor under this Section 10, its employees and agents, shall cooperate
fully with Licensee and its legal representatives in the
investigation and defense of any action, claim or liability covered
by this indemnification.

During the term of this Agreement, Licensee shall maintain at its
own expense:





10.3.1.  Comprehensive
general liability insurance for claims for damages arising from
bodily injury (including death) and property damages caused by, or
arising out of, acts or omissions of its employees, in such amounts
as are customary and reasonable in the Licensee’s
industry.





10.3.2.  Product
liability insurance in such amounts as are customary and reasonable
in the Licensee’s industry.





10.3.3.  Maintenance
of such insurance coverage shall not relieve Licensee of any
responsibility under this Agreement for damage in excess of the
insurance limits.





11.  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 to the extent, and for so long as, such failure or delay
is caused by or results from Force Majeure events.
