arising as a result of (a) any breach of representations or warranties of Licensor provided in Section 9.1; (b) any Product
Liability Claims or mandatory or voluntary recall of the Product in any jurisdiction of the Territory, if and to the extent that

to the Party against whom indemnity is sought (the “Indemnifying Party”) of the assertion or commencement of
any claim for indemnification pursuant to this Section 10, and shall provide the Indemnifying Party such information with
respect thereto that the Indemnifying Party may reasonably request. The failure to give such notice will relieve the Indemnifying
Party of its indemnification obligations hereunder only to the extent that the Indemnifying Party has suffered actual prejudice
thereby. The Indemnifying Party shall assume and control the defense and settlement of any such action, suit or proceeding at its
own expense. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in such
defense, at the Indemnifying Party’s expense, subject to the following. The Indemnified Party will be entitled at its own
expense to participate in such defense and to employ separate counsel for such purpose. For so long as the Indemnifying Party is
diligently defending any action, suit or proceeding pursuant to this Section 10, the Indemnifying Party will not be liable

which commits the other Party to take, or to forbear to take, any action without the other Party’s prior written consent.

12.2    Term
and Rules Post Termination:


 


(a)          Termination
for Cause. In the event any Party (or an Affiliate of a Party, as applicable) is in breach of any material obligation under
this Agreement, the JV Agreement or the Pan-Asia License Agreement (the “Breaching Party”), the non-breaching
Party may give written notice to the Breaching Party specifying the claimed particulars of such breach, and in the event such material
breach is not cured, within sixty (60) days following the date of such written notification, without prejudice to any other rights
and remedies available at any time to the non-breaching Party, the non-breaching Party shall have the right thereafter to terminate
this Agreement; provided, however, that if such breach is incapable of being cured, then such termination may be
effective immediately upon such written notice to the Breaching Party. Notwithstanding the foregoing, Licensor shall have the right
to terminate this Agreement in the event Licensee fails to timely make the payments required by Section 5.2 of this Agreement
and such failure continues for ten (10) Business Days following such written notice.

(e)         Termination

shall have, in addition to all other legal and equitable rights and remedies available hereunder, the option to terminate this
Agreement upon sixty (60) days written notice to the Bankrupt Party. It is agreed and understood that if the Other Party does not
elect to terminate this Agreement upon the occurrence of an Event of Bankruptcy, except as may otherwise be agreed with the trustee
or receiver appointed to manage the affairs of the Bankrupt Party, the Other Party shall continue to make all payments required
of it under this Agreement as if the Event of Bankruptcy had not occurred, the Bankrupt Party shall not have the right to terminate
any license granted herein. The term “Event of Bankruptcy” means: (i) filing in any court or agency pursuant to any
statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement
or for the appointment of a receiver or trustee of the Bankrupt Party or of its assets; (ii) proposing a written agreement of composition

limitation, the Bankrupt Party’s rights under this Agreement shall include those rights afforded by 11 U.S.C. § 365(n)
of the United States Bankruptcy Code (the “Bankruptcy Code”) and any successor thereto. If the bankruptcy trustee of
a Bankrupt Party as a debtor or debtor-in-possession rejects this Agreement under 11 U.S.C. § 365(o) of the Bankruptcy Code,
the Other Party may elect to retain its rights licensed from the Bankrupt Party hereunder (and any other supplementary agreements
hereto) for the duration of this Agreement and avail itself of all rights and remedies to the full extent contemplated by this
Agreement and 11 U.S.C. § 365(n) of the Bankruptcy Code, and any other relevant laws.

the extent not transferred pursuant to Section 13.3(a), Licensee shall provide to Licensor a copy of any and all documentation
and data owned by Licensee and in tangible form at the time of termination of the Agreement that has been generated with respect
to the Product and is necessary to enable Licensor to continue development of a Product and the commercialization thereof in the
Territory (collectively, the “Licensee Product Data”), and Licensor may use such Licensee Product Data at its
discretion on an exclusive basis, to the extent necessary to enable Licensor, its Affiliates and Third Parties on behalf of Licensor
or its Affiliates to continue to develop and commercialize a Product in the Territory; and


 


(ii)         if
such termination occurs after a Product has received Regulatory Approval, Licensee shall, if permitted under applicable Law, promptly
transfer and deliver to Licensor original copies of any and all Regulatory Approvals obtained in connection with the Product in
the Territory (including any and all official registrations, licenses, permits, certificates, and/or importation documents issued
by Regulatory Authorities in the Territory), as well as any and all regulatory documentation and applications for Regulatory Approval
submitted to Regulatory Authorities in the Territory in connection with the Product; Licensor shall pay Licensee’s direct,
out-of-pocket costs for compliance with this Section 12.3(b)(ii);


 


(iii)        to
the extent that any Regulatory Approval is issued in the name of Licensee, its Affiliates, Sublicensees or other designee, Licensee
shall, to the extent permitted by applicable Law, promptly assign or procure the assignment to Licensor (or its designee) such
Regulatory Approvals, and in the event assignment is not permitted under applicable Law or cannot be carried out for any other
reason, the Licensee shall take all steps that are necessary and/or desirable to assist Licensor to obtain such Regulatory Approvals
in the name of Licensor (or its designee) in the Territory, with such actions including without limitation coordinating with the
applicable Regulatory Authority, furnishing all necessary information and documents in respect thereof, and promptly cancelling
and terminating (as necessary) all Regulatory Approvals held by the Licensee, its Affiliate(s), Sublicensee(s) and/or other designee(s)
which are not otherwise assignable or transferable to the Licensor (or its designee); Licensor shall pay Licensee’s direct,
out-of-pocket costs for compliance with this Section 12.3(b)(iii); and


 


(iv)        Licensee
shall assign (or cause its Affiliates to assign) to Licensor all agreements with any Third Party with respect to the conduct of
clinical trials for the Product, including agreements with contract research organizations, clinical sites and investigators, unless
expressly prohibited by any such agreement or unless such agreement covers clinical trials for products in addition to the Products
(in which case Licensee shall cooperate with Licensor in all reasonable respects to secure the consent of such Third Party to such
assignment or to the conclusion of a new agreement between the Licensor and the Third Party on terms substantially similar to the
agreement between Licensee and the Third Party), and Licensor shall assume all obligations under all such agreements.


 


(c)         Survival
of Sublicenses. All sublicenses granted by Licensee to Sublicensees shall survive termination of this Agreement, and Licensor
shall assume all such sublicenses as the Licensor thereunder in accordance with the terms of such sublicenses; provided,
however, that Licensor may elect to terminate any such sublicenses, and Licensor shall not be required under this Section
12 to assume obligations under any such sublicense that are greater in scope than those set forth in this Agreement.

Exhibit B


 


PHS LICENSE TERMS


APPLICABLE TO LICENSEE


 


Terms in bold have the meanings given such terms in the PHS
License.


 


		5.01	PHS reserves on behalf of the Government
an irrevocable, nonexclusive, non-transferable, royalty-free license for the practice of all inventions licensed under the Licensed
Patent Rights throughout the world by or on behalf of the Government and on behalf of any foreign government or international
organization pursuant to any existing or future treaty or agreement to which the Government is a signatory. Prior to the
First Commercial Sale, Licensee agrees to provide PHS reasonable quantities of Licensed Products or
materials made through the Licensed Processes solely for PHS research use and not for purposes of commercial development,
manufacture or distribution, at a price equal to Licensee’s cost of such.



 


		5.02	Licensee agrees that products used or sold in
the United States embodying Licensed Products or produced through use of Licensed Processes shall be manufactured
substantially in the United States, unless a written waiver is obtained in advance from PHS.



 


		5.03	Licensee acknowledges that PHS may enter
into future Cooperative Research and Development Agreements (CRADAs) under the Federal Technology Transfer Act of 1986 that relate
to the subject matter of this Agreement. PHS agrees to notify Licensee, as soon as is practical of any proposed
CRADA that relates to the subject matter of this Agreement. Licensee agrees not to unreasonably deny requests for
a Research License from such future collaborators with PHS when acquiring such rights is necessary in order to make
a Cooperative Research and Development Agreement (CRADA) project feasible. As of the effective date of this Agreement,
Licensee requests that Licensee have an opportunity to join as a party to any proposed Cooperative Research and
Development Agreement (CRADA).



 


		5.04	In addition to the reserved license of Paragraph 5.01
above, PHS reserves the right to grant such nonexclusive Research Licenses directly or to require Licensee
to grant nonexclusive Research Licenses on commercially reasonable terms. The purpose of this Research License is
to encourage basic research, whether conducted at an academic or corporate facility. In order to safeguard the Licensed Patent
Rights, however, PHS shall consult with Licensee before granting to commercial entities a Research License
or providing to them research samples of Licensed Products or materials made through the Licensed Processes,
provided however that PHS will not provide materials obtained from Licensee under Paragraph 5.01 above to third
parties, except with Licensee’s prior written consent, which shall not be unreasonably withheld.



 


		8.01	Licensee agrees to keep accurate and correct records
of Licensed Products made, used, sold, or imported and Licensed Processes practiced under this Agreement
appropriate to determine the amount of royalties due PHS. Such records shall be retained for at least five (5) years
following a given reporting period and shall be available during normal business hours upon five (5) business days prior written
notice from PHS to Licensee for inspection at the expense of PHS by an accountant or other designated auditor
selected by PHS for the sole purpose of verifying reports and payments hereunder. The accountant or auditor shall only
disclose to PHS information relating to the accuracy of reports and payments made under this Agreement. If an inspection
shows an under reporting or underpayment in excess of five percent (5%) for any twelve (12) month period, then Licensee shall
reimburse PHS for the cost of the inspection at the time Licensee pays the unreported royalties, including any late
charges as required by Paragraph 9.08 of this Agreement. All payments required under this Paragraph shall be due within
thirty (30) days of the date PHS provides Licensee notice of the payment due.

best efforts to bring the Licensed Products and Licensed Processes to Practical Application. “Reasonable
best efforts” for the purposes of this provision shall include substantial adherence to the Commercial Development Plan
at Appendix F and substantial performance of the Benchmarks at Appendix E as may be amended from time to time by mutual
written consent. The efforts of sublicensees and Affiliates shall be considered the efforts of Licensee. To the extent
that the Benchmarks or development obligations set forth in Appendix E differ from or conflict with those set forth in
the Commercial Development Plan in Appendix F, Appendix E shall be considered to supersede Appendix F and the Commercial
Development Plan in Appendix F shall be amended to be consistent with Appendix E.



 


		10.02	Upon the First Commercial Sale, until the expiration
of this Agreement, Licensee shall use its reasonable best efforts to make Licensed Products and Licensed
Processes reasonably accessible to the United States public.



 


		12.05	Licensee shall indemnify and hold PHS,
its employees, students, fellows, agents, and consultants (the “Indemnified Parties”) harmless from and against
all liability, demands, damages, expenses, and losses, including but not limited to death, personal injury, illness, or property
damage (the “Indemnified Losses”) suffered by an Indemnified Party in connection with or arising out
of a) the use by or on behalf of Licensee, its sublicensees, directors, employees, or third parties of any Licensed
Patent Rights, or b) the design, manufacture, distribution, or use of any Licensed Products, Licensed Processes
or materials by Licensee, or other products or processes developed in connection with or arising out of the Licensed
Patent Rights. Licensee agrees to maintain a liability insurance program consistent with sound business practice. Notwithstanding
any other provision to the contrary, Licensee shall have no obligation to indemnify an Indemnified Party from an
Indemnified Loss in connection with or arising out of the design, manufacture, distribution or use of any Licensed Product
or Licensed Process by or on behalf of the Indemnified Party.



 


		13.05	PHS shall specifically have the right to terminate
or, with Licensee’s consent, modify, at its option, this Agreement, if PHS determines that the Licensee:
1) is not using its reasonable best efforts to effectuate the Commercial Development Plan submitted with its request
for a license and the Licensee cannot otherwise demonstrate to PHS’s satisfaction that the Licensee
has taken, or can be expected to take within a reasonable time, effective steps to achieve Practical Application of the
Licensed Products or Licensed Processes; 2) has not used its reasonable best efforts to achieve the Benchmarks
as my be modified under Paragraph 9.02; 3) has willfully made a false statement of, or willfully omitted, a material
fact in the license application or in any report required by this Agreement; 4) has committed a material breach of
a covenant or agreement contained in the license; 5) is not keeping Licensed Products or Licensed Processes
reasonably available to the public after commercial use commences; 6) cannot reasonably satisfy unmet health and safety needs;
or 7) cannot reasonably justify a failure to comply with the domestic production requirement of Paragraph 5.02 unless waived.
In making this determination, PHS will take into account the normal course of commercial development programs conduct with
sound and reasonable business practices and judgment and the annual reports submitted by Licensee under Paragraph 9.02.
Prior to invoking this right, PHS shall give written notice to Licensee providing Licensee specific notice
of, and a ninety (90) day opportunity to respond to, PHS’s concerns as to the previous items 1) to 7). If Licensee
fails to alleviate PHS’s concerns as to the previous items 1) to 7) or fails to initiate corrective action to
PHS’s reasonable satisfaction, PHS may terminate this Agreement.

for public use specified by federal regulations issued after the date of the license and such requirements are not reasonably
satisfied by Licensee.



 


		13.08	Within thirty (30) days of receipt of written notice
of PHS’s unilateral decision to modify or terminate this Agreement, Licensee may, consistent with the
provisions of 37 C.F.R. 404.11, appeal the decision by written submission to the designated PHS official. The decision of the
designated PHS official shall be the final agency decision. Licensee may thereafter exercise any and all administrative
or judicial remedies that may be available.
