 2.3 Sublicensing Rights. 
  
 2.3.1 Ability to Sublicense. Upon written approval by
PHS, which approval will not be unreasonably withheld, nor will a decision on approval be unduly delayed, KSA may enter into sublicensing agreements under the Licensed Patent Rights subject to the Royalty obligations set forth in Section 4.1 herein,

	3.	DOMESTIC AND FOREIGN PATENT FILING, PROSECUTION AND
MAINTENANCE; PATENT ENFORCEMENT. 

  
 3.1 Filing, Prosecution and Maintenance. PHS has responsibility for the preparation, filing, prosecution, and maintenance of any and all patent
applications included in the Licensed Patent Rights and shall furnish copies of relevant patent-related documents as PHS deems necessary to AH who agrees to furnish such copies to KSA. As between the parties, PHS shall have the sole right to conduct
the preparation, filing, prosecution and maintenance of any and all patent applications or patents included in the Licensed Patent Rights. KSA shall promptly inform PHS and AH as to all matters that come to its attention that may affect the
preparation, filing, prosecution, or maintenance of the Licensed Patent Rights; KSA may provide comments and suggestions to AH and PHS with respect to such preparation, filing and maintenance. 
  
 3.2 Patent Enforcement. KSA agrees to notify AH and PHS promptly of
each infringement or possible infringement, as well as any facts which may affect the validity, scope, or enforceability of the Licensed Patent Rights of which KSA becomes aware. Except as set forth herein, as between the parties, AH and PHS shall
have the sole right to pursue claims of infringement of the Licensed Patent Rights against third parties; provided, however, that AH neither represents nor warrants that it will commence legal actions against third parties infringing the Licensed
Patent Rights. 
  
 3.3 Potential Enforcement by KSA.
Pursuant to this Agreement and the provisions of Chapter 29 of Title 35, United States Code, KSA may: a) bring suit in its own name, at its own expense, and on its own behalf for infringement of presumably valid claims in the Licensed Patent Rights;
b) in any such suit, engage infringement and collect for its use, damages, profits, and awards of whatever nature recoverable for such infringement; and c) settle any claim or suit for infringement of the Licensed Patent Rights provided, however,
that PHS and appropriate Government authorities shall have the first right to take such actions and shall have a continuing right to intervene in such suit. KSA shall take no action to compel the Government either to initiate or to join in any such
suit for patent infringement. KSA may request the Government to initiate or join any such suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any such suit, KSA shall reimburse the Government for any costs,
expenses, or fees which the Government incurs as a result of such motion or other action, including any 

  

 4 








 
and all costs incurred by the Government in opposing any such motion or other action. Upon KSA s payment of all costs incurred by the Government, as a result
of KSA s joinder motion or other action, these actions by KSA will not be considered a default in the performance of any material obligation under this Agreement. In all cases, KSA agrees to keep PHS and AH reasonably apprised of the status and
progress of any litigation. Before KSA commences an infringement action, KSA shall notify PHS and give careful consideration to the views of PHS and to any potential effects of the litigation on the public health in deciding whether to bring suit.

  
 3.4 AH Cooperation in KSA Enforcement Actions. AH shall
cooperate fully with KSA in connection with an infringement action initiated under Section 3.3. AH agrees promptly to provide access to all necessary documents and to render reasonable assistance in response to a request by KSA at KSA s expense.

  
 3.5 Declaratorv Judgment Actions. In the event that a
declaratory judgment action alleging invalidity or non-infringement of any of the Licensed Patent Rights shall be brought against KSA or raised by way of counter claim or affirmative defense in an infringement suit brought by KSA under Section 3.3,
pursuant to this Agreement and the provisions of Chapter 29 of Title 35, United States Code or other statutes, KSA may: a) defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the Licensed Patent
Rights; b) in any such suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of whatever nature recoverable for such infringement; and c) settle any claim or suit for declaratory judgment involving the
Licensed Patent Rights provided, however, that PHS and appropriate Government authorities shall have the first right to take such actions and shall have a continuing right to intervene in such suit. KSA shall take no action to compel the Government
either to initiate or to join in any such declaratory judgment action. KSA may request the Government to initiate or join in any such suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any such suit by motion
or any other action of KSA, KSA shall reimburse the Government for any costs, expenses, or fees which the Government incurs as a result of such motion or other action. Upon KSA s payment of all costs incurred by the Government as a result of KSA s
joinder motion or other action, these actions by KSA will not be considered a default in the performance of any material obligation under this Agreement. If KSA elects not to defend against such declaratory judgment action, PHS, at its option, may
do so at its own expense. In all cases, KSA agrees to keep AH reasonably apprised of the status and progress of any litigation. Before KSA commences an infringement action, KSA shall notify PHS and AH and give careful consideration to the views of
PHS and to any potential effects of the litigation on the public health in deciding whether to bring suit. 
  

	4.	PAYMENTS. 

  
 4.1 Royalty. The parties agree and acknowledge that pursuant to Section 2.6.1 of the Primary Sublicense Agreement, the license granted pursuant to
Article 2 of this Agreement is granted for no additional payments beyond those set forth in the Primary Sublicense Agreement, except only as set forth in Section 4.2. Accordingly, KSA shall not owe any additional royalties under this Agreement for

terms of Section 4.1, after expiration of the last to expire of the Licensed Patent Rights, as defined in the Primary Sublicense Agreement, and until expiration of the last to expire of the Licensed Patent Rights, as-defined herein, KSA shall pay AH a royalty of * of Net Sales as defined in this Agreement and, without duplication, Net Sales as
defined in the Primary Sublicense Agreement (without regard to the term of any patent) in combination with Net Sales as defined in this Agreement. KSA further agrees that the total earned royalties due to AH can rise to a maximum total of * should
the provisions of the related non-exclusive patent licenses, the Manufacturing Patent License Agreement and Chloroquine Patent Sublicense Agreement between the parties and dated on even date herewith, be in effect. In such a case, * under this

this Agreement are exclusive of all sales, use, value-added, withholding, and other taxes and duties. KSA will pay all taxes and duties assessed in connection with this Agreement and its performance by any authority within or outside of the U.S.,
except for taxes payable on AH s net income. AH will be promptly reimbursed by KSA for any and all taxes and duties that AH may be required to pay in connection with this Agreement or its performance. AH shall cooperate and assist KSA with any steps
that may be required to minimize the payment of taxes and duties under this Section or recover part or all of any taxes or duties paid under this Section. All amounts which remain unpaid after its due date shall be subject to interest charges at the

written report shall so state. The Royalty report shall be certified as correct by an authorized officer of KSA. 
  
 5.3 Additional Reports. AH and KSA acknowledge that KSA is obligated to submit certain written reports to PHS and AH under the Primary Sublicense

	11.	GENERAL PROVISIONS. 

  
 11.1 Waiver. Neither party may waive or release any of its rights or interests in this Agreement except in writing.
The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver or that right by either party or excuse a similar subsequent failure to perform any such
term or condition by this other party. 
  
 11.2 Entire
Agreement. Save only as provided in the Primary Sublicense Agreement and the Existing Drug Delivery Agreement, this Agreement constitutes the entire agreement between the Parties relating to the subject matter of the Licensed Patent Rights and
all prior negotiations, representations, agreements, and understandings are merged into, extinguished by, and completely expressed by this Agreement. 
  
 11.3 Severability. The provisions of this Agreement are severable, and in the event that any provision of this Agreement shall be determined to be
invalid or unenforceable under any controlling body of law, such determination shall not in any way affect the validity or enforceability of the remaining provisions of this Agreement. 
  
 11.4 Modification. If either party desires a modification to this Agreement, the Parties shall, upon reasonable
notice of the proposed modification by the party desiring the change, confer in good faith to determine the desirability of such modification. No modification will be effective until a written amendment is signed by the signatories to this
Agreement. 
  
 11.5 Governing Law; Dispute Resolution. The
construction, validity, performance, and effect of this Agreement shall be governed by the laws of New Jersey and of the United States, excepting those portions thereof relating to conflicts of law. All disputes arising under this Agreement shall be
resolved solely in the federal or state courts situated in New Jersey and both parties hereby submit to the personal jurisdiction thereof. 
  
 11.6 Notices. All notices required or permitted by this Agreement shall be given by prepaid, first class, registered or certified mail properly
addressed to the other party at the address designated on the first page of this Agreement, or to such other address as may be designated in writing by such other party, and shall be effective as of the date of the postmark of such notice.

  
 11.7 Assignment. This Agreement shall not be assigned
by KSA except (a) with the prior written consent of AH, such consent to be reasonably given; or (b) as part of a sale or transfer of substantially the entire business of KSA relating to operations which concern this Agreement. KSA shall notify AH
within ten (10) days of any assignment of this Agreement by KSA. In the event that any such assignment by KSA shall cause a payment to be due from AH

to PHS under Section 14.07 of the Existing Drug Delivery Agreement, KSA shall promptly make such payment to AH for delivery to PHS. 
  
 11.8 Use of Items from AH and its Licensors. KSA agrees in its use of
any AH supplied items to comply with all applicable statutes, regulations, and guidelines, including Public Health Service and National Institutes of Health Regulations and guidelines. KSA agrees not to use the materials for research involving human
subjects or clinical trials in the United States without complying with 21 CFR Part 50 and 45 CFR Part 46. KSA agrees not to use the items for research involving human subjects or clinical trials outside of the United States without notifying AH, in
writing, of such research or trials and complying with the applicable regulations of the appropriate national control authorities. Written notification to AH of research involving human subjects or clinical trials outside of the United States shall
be given no later than sixty (60) days prior to commencement of such research or trials. 
  
 11.9 Export Control. KSA acknowledges that it is subject to and agrees to abide by the United States laws and regulations (including the Export Administration Act of 1979 and Arms Export Control Act)
controlling the export of technical data, computer software, laboratory prototypes, biological material, and other commodities. The transfer of such items may require a license from the cognizant agency of the U.S. Government or written assurances
by KSA that it shall not export such items to certain foreign countries without prior approval of such agency. AH neither represents nor warrants that a license is or is not required or that, if required, it shall be issued. 
  
 11.10 Marking of Licensed Products. KSA agrees to mark the Licensed
Products or their packaging sold in the United States with all applicable U.S. patent numbers and similarly to indicate Patent Pending status. All Licensed Products manufactured in, shipped to, or sold in other countries shall be marked in such a
manner as to preserve AH’s or its licensor’s patent rights in such countries. 
  
 11.11 Survival. Sections 2.3.3, 2.4, 4, 7, 8, 9 and 11 of this Agreement shall survive termination of this Agreement.

 PHS FLOWTHROUGH TERMS 
  
 1. Manufacturing in US for US Distribution. KSA 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. 
  
 2. Government Reserved Rights. Prior to the initial transfer by or on behalf of KSA or its sublicensees of Licensed Products or the initial
practice of a Licensed Process by or on behalf of KSA or its sublicensees in exchange for cash or some equivalent to which value can be assigned for the purpose of determining Net Sales, KSA agrees to provide PHS reasonable quantities of Licensed
Products or materials made through the Licensed Processes for PHS research use. 
  
 3. Recordkeeping and Audits. KSA agrees to keep accurate and correct records of Licensed Products made, used, or sold and Licensed Processes practiced under this Agreement appropriate to determine the amount of
royalties due AH. Such records shall be retained for at least five (5) years following a given reporting periods. They shall be available during normal business hours at KSA’s premises 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 (5%) percent for any twelve (12) month period, then KSA shall pay the unreported Royalties, including any late charges as required by Section 4.5 of this Agreement. All
payments required under this Section shall be due within thirty (30) days of the date PHS provides KSA notice of the payment due. 
  
 7. Efforts to Commercialize. KSA shall use its reasonable best efforts to introduce the Licensed Products into the commercial market or apply the
Licensed Processes to commercial use as soon as practicable. Reasonable best efforts for the purpose of this provision shall include, but not be limited to, adherence to the Commercial Development Plan. The efforts of a sublicensee shall be
considered the efforts of KSA. 
  
 8. Efforts to Make Available
to Public. Upon first commercial sale, until the expiration of this Agreement, KSA shall use the reasonable best efforts to keep Licensed Products and Licensed Processes reasonably accessible to the public in the Licensed Territory. 

 
 9. Indemnification by KSA. KSA shall indemnify and hold AH and PHS,
its employees, students, fellows, agents, and consultants harmless from and against all liability, demands, damages, expenses, and losses, including but not limited to death, personal injury, illness, or property damage in connection with or arising
out of (a) the use by or on behalf of KSA, 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 other products
or processes developed in connection with or arising out of the Licensed Patent Rights. KSA agrees to maintain a liability insurance program consistent with sound business practice. 
  









 10. PHS reserves the right according to 35 U.S.C. Section 209(f)(4) to terminate or modify this Agreement
if it is determined that such action is necessary to meet requirements for public use specified by Federal regulations issued after the date of the license and such requirements are not reasonably satisfied by KSA. 
  
 11. Within thirty (30) days of receipt of PHS unilateral decision to modify
or terminate this Agreement, KSA may, consistent with the provisions of 37 CFR Section 404.11, appeal the decision by written submission to the Director of NIH or designee. The decision of the NIH Director or designee shall be the final agency
decision. KSA may thereafter exercise any and all administrative or judicial remedies that may be available. 
  
 12. Within ninety (90) days after termination or expiration of this Agreement, a final report shall be submitted by KSA. Any royalty payments, including
those related to patent expense, due to AH or PHS shall become immediately due and payable upon termination or expiration. If terminated, sublicensees may elect to convert their sublicenses to direct licenses with PHS in accordance with the terms of
this Agreement.
