  Article 2

    

    Option; Licenses; Technology Transfer

   

  2.1          Research License and Option.

   

  (a)           Research License. GigaGen hereby grants to
    Kineta, during the Option Term prior to the Option Exercise Date, an exclusive license under the Licensed Research Technology, with the right to grant sublicenses solely to Kineta’s Affiliates and Third Parties conducting research activities on
    Kineta’s behalf, to conduct research on the GigaGen Antibodies, including to make derivatives thereof. GigaGen shall not grant any Third Party any rights or licenses with respect to the GigaGen Antibodies during the Option Term that would prevent it
    from granting the license to Kineta in Section 2.2.

   

  (b)           Option. GigaGen hereby grants Kineta an
    exclusive option during the Option Term to obtain the exclusive license in Section 2.2(a). Kineta may exercise such option by providing the Option Exercise Notice to GigaGen at any time during the Option Term.

   

  2.2          License to Licensed Antibodies.

   

  (a)           License to Kineta. Effective upon Kineta’s
    exercise of the option referenced in Section 2.1(b), GigaGen hereby grants to Kineta an exclusive (even as to GigaGen) license, with the right to grant sublicenses through multiple tiers, under the Licensed Technology to research, develop, make, have
    made, use, have used, offer for sale, sell, have sold, distribute, import, have imported, export and have exported and otherwise exploit Licensed Antibodies and Licensed Products in the Field in the Territory.

   

  (b)           Sublicenses. Kineta shall have the right to
    grant sublicenses through multiple tiers under any or all of the rights granted in Section 2.2(a) to its Affiliates and to Third Parties. Each such sublicense shall be consistent with and subject to the terms and conditions of this Agreement. In the
    event that GigaGen terminates this Agreement pursuant to Section 10.3, each sublicense granted by Kineta to a Third Party will survive such termination (as a direct license from GigaGen) pursuant to Section 10.4(b).

   

  2.3          No Implied Licenses. Except as explicitly set
    forth in this Agreement, neither Party shall be deemed by estoppel or implication to have granted the other Party any license or other right to any intellectual property of such Party.

   

  2.4          Restriction With Respect to Non-Licensed
      Antibodies. GigaGen shall not, and shall ensure that its Affiliates do not, during the period commencing on the Option Exercise Date and ending on the fourth (4th)
    anniversary of the Option Exercise Date (the “Exclusivity Period”), collaborate with, license, sell, assign, transfer or grant any rights to any Third Party with respect to any Non-Licensed Antibody, including the research, optimization,
    development, manufacture or commercialization thereof. If any entity that is a Third Party as of the Option Exercise Date becomes an Affiliate of GigaGen during the Exclusivity Period, then the foregoing restriction will continue to apply to such Third
    Party and will also apply to GigaGen and its Affiliates. For clarity, the foregoing does not restrict GigaGen from: (a) discovering, developing, out-licensing or commercializing any antibodies directed against the Target that are not GigaGen
    Antibodies, at any time during the Term (including during the Exclusivity Period), (b) granting any rights to a Third Party with respect to any Non-Licensed Antibody after the Exclusivity Period or (c) subject to the preceding sentence, itself
    internally developing and commercializing any Non-Licensed Antibody during the Term, provided that no Third Party (including any entity that was a Third Party on the Option Exercise Date) is granted any rights to any Non-Licensed Antibody.

  2.5          Reciprocal Research Licenses.

   

  (a)           

  GigaGen hereby grants to Kineta
    a perpetual, irrevocable, non-exclusive, non-sublicensable, royalty-free and fully paid-up license under any Study IP that does not constitute Joint Study IP (as defined in the MTA), for all Research Purposes.

   

  (b)           

  Kineta hereby grants to GigaGen
    a perpetual, irrevocable, non-exclusive, non-sublicensable, royalty-free and fully paid-up license under the Study IP for all Research Purposes; provided, however, that GigaGen shall not publicly disclose any results obtained in connection with the
    exercise of such license without obtaining the prior written consent of Kineta (which may be withheld in Kineta’s sole discretion).

   

  (c)           The foregoing license grants in this Section
    2.5 supersede the licenses granted in Section 4.5 of the MTA, which are hereby terminated.

   

  2.6          Termination of MTA. The Parties hereby
    terminate the MTA by mutual agreement, such termination to be effective on the Effective Date. Notwithstanding Section 10.2 of the MTA to the contrary, (a) Kineta shall not be obligated to return to GigaGen or destroy any Materials (as defined in the
    MTA) or Confidential Information (as defined in the MTA) of GigaGen that relate to the Licensed Antibodies, and (b) only the following provisions of the MTA will survive termination thereof, and all other provisions are terminated: Section 4.3, 8, 9,
    11(b), 11(g) and 11(h). The Parties acknowledge and agree that in the event of a conflict between any surviving provision of the MTA and a provision of this Agreement, the relevant provision of this Agreement shall control in all cases.

   

  2.7          Trianni Agreement. GigaGen shall not,
    without the prior written consent of Kineta, (a) take any action with respect to the Trianni Agreement (including amending, terminating or otherwise modifying) that diminishes the rights granted to Kineta under this Agreement, or (b) fail to take any
    action with respect to the Trianni Agreement (including failing to pay any amounts owed under such agreement) that is reasonably necessary to avoid diminishing the rights granted to Kineta under this Agreement. GigaGen shall promptly provide Kineta
    with a true, complete and correct copy of any amendment to or material correspondence regarding the Trianni Agreement that would be reasonably likely to affect Kineta’s rights hereunder. In the event that GigaGen receives written notice of an alleged
    breach by GigaGen under the Trianni Agreement, then GigaGen will promptly, but in no event less than five (5) days thereafter, provide written notice thereof to Kineta and grant Kineta the right (but not the obligation) to cure such alleged breach, and
    if Kineta elects to and does cure such breach, then Kineta may offset any such reasonable out-of-pocket costs and expenses incurred by or on behalf of Kineta in connection with curing such breach against Kineta’s future payment obligations to GigaGen
    under this Agreement. Each Party shall notify the other Party if it intends to cure such breach and again promptly after curing such breach.

    Technology Transfer; Development and Commercialization

   

  3.1          Technical Support. As reasonably requested
    by Kineta, GigaGen shall provide, at no additional cost or expense to Kineta, reasonable technical support (by teleconference, by electronic means or in-person at GigaGen’s facilities during regular business hours and upon reasonable advance notice, as
    needed) to support Kineta in the exercise of its rights or performance of its obligations in connection with the Selected Antibodies, including in connection with the technology transfer of the Licensed Know-How (which transfer was conducted prior to
    the Effective Date).

   

  3.2          Development and Commercialization of Licensed
      Products. As between the Parties, Kineta shall have sole control, authority, and discretion over the research, development, manufacture and commercialization of Licensed Products throughout the world, subject to Section 3.3. If Kineta sells any
    Licensed Product as part of a bundle, or as part of a combination therapy where Kineta has the right to sell and set the price of the other component of the combination therapy, then Kineta shall not disproportionately discount, in a manner
    inconsistent with the relative value of the components of such combination therapy or bundle, the pricing of the Licensed Product relative to the other components. Kineta shall not use any Licensed Product as a loss leader.

   

  3.3          Diligence.  Kineta shall use Commercially
    Reasonable Efforts to develop and commercialize a Licensed Product in the Field in the United States, whether alone or with or through one (1) or more Affiliates or Sublicensees. For purposes of this Section 3.3, the efforts of each Affiliate or
    Sublicensee shall be considered efforts of Kineta.

   

  Article 4

    after the Effective Date, Kineta shall pay to GigaGen a one-time payment of [***] in connection with Kineta’s completion of the Initial Evaluation Plan and its designation of the evaluation program with a Go Decision (as referenced in the MTA). The
    payment provision in this Section 4.1 supersedes the payment provision in Section 5(b) of the MTA, which is terminated pursuant to Section 2.6, and the Parties agree that payment under this Section 4.1 will be deemed timely satisfaction of Kineta’s
    payment obligation under Section 5(b) of the MTA.

   

  
    12 

    
      
 

  

   

  4.2          Upfront Payment. Within sixty (60) days
    after the Option Exercise Date, Kineta shall (i) pay to GigaGen a one-time upfront payment of [***] and (ii) issue to GigaGen, pursuant to Kineta’s standard form of stock issuance agreement to be entered into between the parties, shares of non-voting
    common stock of Kineta having an aggregate value (at the then-current fair market value) of [***].

   

  4.3          Development and Regulatory Milestone Payments.
    Kineta shall notify GigaGen within thirty (30) days after the first achievement of each milestone event in the table below by Kineta or its Affiliate or Sublicensee. Thereafter, GigaGen may invoice Kineta for the corresponding milestone payment, and
    Kineta shall pay such invoice within sixty (60) days after the achievement of such milestone event.

   

  	 	Development Milestone Event	Milestone Payment 
	 	Engineering Batch Release	[***]

	 	First approval of a BLA for a Licensed Product by the EMA 	[***]
	 	First approval of a BLA for a Licensed Product in Japan	[***]


   

  Each milestone payment set forth above shall be payable only once, regardless of the number of times the applicable milestone event is achieved by
    any Licensed Product and regardless of the number of Licensed Products to achieve the applicable milestone event. Under no circumstances shall Kineta be obligated to pay GigaGen more than twenty million two hundred fifty thousand Dollars ($20,250,000)
    under this Section 4.3.

   

  
    13 

    
      
 

  

   

  4.4            Sales Milestone Payments. Kineta shall
    make the following milestone payments to GigaGen within ninety (90) days after the end of the calendar year in which the annual Net Sales by Kineta and its Affiliates and Sublicensees of all Licensed Products first reach each of the amounts specified
    below. Each such sales milestone payment shall be payable one time only. Notwithstanding the foregoing, in the event that both of the sales milestone payments below are earned concurrently in any one calendar year, then (a) the first sales milestone
    payment (namely, for the payment of [***] will be payable when due, and (b) the second milestone payment (namely, for the payment of [***] will be due and payable by Kineta if and when the annual Net Sales by Kineta and its Affiliates and Sublicensees
    of all Licensed Products reaches the threshold described in such second milestone in a subsequent calendar year.

   

  	 	Sales Milestone Event	Milestone Payment
	 	The aggregate Net Sales of Licensed
          Products in the Territory in a calendar year exceed two hundred million Dollars ($200,000,000)	[***]
	 	The aggregate Net Sales of Licensed
          Products in the Territory in a calendar year exceed five hundred million Dollars ($500,000,000)	[***]


   

  Under no circumstances shall Kineta be obligated to pay GigaGen more than eight million Dollars ($8,000,000) pursuant to this Section 4.4.

   

  4.5          Royalties.

   

  (a)           Royalty Rate. Subject to Sections 4.5(b) and
    (c), Kineta shall pay to GigaGen royalties equal to [***] of annual Net Sales of each Licensed Product in the Field in the Territory during the applicable Royalty Term, on a Licensed Product-by-Licensed Product and country-by-country basis.

   

  (b)           Royalty Term. Royalties shall be paid under
    this Section 4.5, on a country-by-country and Licensed Product-by-Licensed Product basis, on Net Sales during the period of time beginning on the First Commercial Sale of such Licensed Product in such country and continuing until the earliest of: (i)
    the expiration of the last-to-expire Valid Claim of the Licensed Patents, Assigned Joint Study Patents, Kineta Sole Patents or Joint Patents in such country that claims the composition of matter of such Licensed Product (a “Covering Claim” for
    such Licensed Product and country); or (ii) ten (10) years after the First Commercial Sale of such Licensed Product in such country; or (iii) sale of a Biosimilar Product to such Licensed Product in such country (the “Royalty Term”). For
    clarity, if there is no Covering Claim for a particular Licensed Product and country, then no royalties will be due on Net Sales in such country.

   

  (c)            Third Party Intellectual Property. Kineta
    may deduct, from any royalties payable to GigaGen under Section 4.5(a), fifty percent (50%) of all consideration paid by Kineta or its Affiliates or Sublicensees for any rights to Third Party intellectual property used in the Licensed Product
    (including its development and manufacture); provided, that under no circumstances shall the royalties payable to GigaGen for any calendar quarter be reduced below fifty percent (50%) of the amounts otherwise due under Section 4.5(a). Kineta may carry
    forward to subsequent calendar quarters any deductions that it was not able to deduct as a result of the foregoing proviso.

    payable to GigaGen under this Agreement shall be paid in Dollars by check or by wire transfer to a bank account specified in writing by GigaGen.

   

  5.2          

  Reports. Within ninety (90) days after the end of each calendar year during the Royalty Term, Kineta shall deliver to GigaGen a statement, on a country-by-country and Licensed Product-by-Licensed Product basis,
    of the amount of gross sales and Net Sales of Licensed Products during the applicable calendar year, and a calculation of the amount of royalty payment due on such sales for such calendar year, taking into account any royalty offsets under Section
    4.5(c). Along with such royalty report, Kineta shall pay GigaGen the royalties due for such calendar year.

   

  5.3          

  Exchange Rate. For Net
    Sales outside the United States, the rate of exchange to be used in computing the amount of currency equivalent in United States dollars shall be made at the rate of exchange published in the Wall Street Journal, Western Edition on the last
    business day of each calendar quarter of the applicable calendar year.

   

  5.4          

  Books and Records. Kineta
    shall keep accurate books and accounts of record in connection with its sales of Licensed Products in sufficient detail to permit verification of Kineta’s payments pursuant to Section 4.4 and 4.5. Kineta shall use commercially reasonable efforts to
    require its Affiliates and Sublicensees to keep accurate books and accounts of records in connection with their sales of Licensed Products for which a royalty is due hereunder. Kineta shall maintain its records for a period of three (3) years from the
    end of the calendar quarter in which sales occurred.

   

  5.5          

  Audit. GigaGen, at its
    expense, through an independent, nationally recognized certified public accountant reasonably acceptable to Kineta, shall have the right to access Kineta’s relevant books and records for the sole purpose of verifying Kineta’s payments to GigaGen
    pursuant to Sections 4.4 and 4.5 during any portion or all of the preceding three (3) years; such access shall be conducted after reasonable prior notice by GigaGen to Kineta during Kineta’s ordinary business hours, shall not be more frequent than once
    during any calendar year (and shall be limited to three (3) consecutive business days of on-site activity), and shall not include any books and records that were previously accessed pursuant to this Section 5.5. Such accountant shall execute a
    confidentiality agreement with Kineta in customary form and shall only disclose to GigaGen whether Kineta paid GigaGen the correct amounts pursuant to Sections 4.4 and 4.5 during the audit period and if not, any information necessary to explain the
    source of the discrepancy. If such audit determines that Kineta paid GigaGen less than the amount properly due and such determination is not subject to a good faith dispute, then Kineta shall promptly pay GigaGen an amount equal to such underpayment,
    and if the amount underpaid exceeds ten percent (10%) of the amount actually due over the audited period, Kineta shall also reimburse GigaGen for the reasonable costs of such audit (including the fees and expenses of the certified public accountant).
    In the event such audit determines that Kineta paid GigaGen more than the amount properly due, then GigaGen shall promptly issue a refund to Kineta of such overpayment.

   

  
    15 

    
      
 

  

   

  5.6          Withholding of Taxes. Any withholding of
    taxes levied by tax authorities on the payments hereunder shall be borne by GigaGen and deducted by Kineta, from the sums otherwise payable by it hereunder, for payment to the proper tax authorities on behalf of GigaGen. Kineta agrees to cooperate with
    GigaGen in the event GigaGen claims exemption from such withholding or seeks deductions under any double taxation or other similar treaty or agreement from time to time in force, such cooperation to consist of providing GigaGen with receipts of payment
    of such withheld tax or other documents reasonably available to Kineta.

    and other rights granted to the other Party under this Agreement or such Party’s obligations under this Agreement (including any exclusivity obligations), each Party shall be entitled to practice, grant licenses to, assign and exploit the Joint
    Inventions and Joint Patents without the duty of accounting or seeking consent from the other Party.

   

  6.2          Joint Study IP. GigaGen hereby assigns to
    Kineta all of GigaGen’s right, title and interest in and to the Joint Study IP, as defined in the MTA (which, for purposes of this Agreement, shall be referred to as “Assigned Joint Study IP”). All Patents claiming Assigned Joint Study IP shall
    be referred to as “Assigned Joint Study Patents”. GigaGen shall fully cooperate with Kineta in obtaining Patent and other proprietary protection for any Assigned Joint Study IP, with such protection being obtained in the name of Kineta and at
    Kineta’s sole cost and expense; provided that, if GigaGen has, prior to the Effective Date, filed any Patents or patent applications or obtained other proprietary protection, in each case, claiming or Covering any Assigned Joint Study IP, all such
    intellectual property shall be included in the definition of “Assigned Joint Study IP” and “Assigned Joint Study Patents”, as applicable, and is subject to the provisions of this Section 6.2 (including, for clarity, the assignment to Kineta hereunder)
    and the remainder of this Agreement. GigaGen will execute and deliver all requested applications, assignments and other documents, and take such other actions as Kineta may reasonably request, in order to perfect and enforce Kineta’s rights in all
    Assigned Joint Study IP.

  Cooperation. Each Party shall fully cooperate with the other Party to execute all lawful papers and instruments and to make all rightful oaths and declarations as may be necessary or useful in the
    preparation and prosecution of the Licensed Patents and Joint Patents. In addition, each Party acknowledges and agrees that it desires to maximize the patentability of the Non-Licensed Antibody Patents and any patents or patent applications that claim
    or Cover any Licensed Antibodies (the “Licensed Antibody Patents”) and shall cooperate with the other Party in order to implement the foregoing, including by filing any Non-Licensed Antibody Patents and Licensed Antibody Patents on the same
    date. Accordingly, the Parties agree to maintain, through assigned intellectual property liaisons of each Party, frequent (i.e., at least quarterly) communication regarding the status of their respective patents or patent applications referenced in
    this Section 6.3(d) and any anticipated filings or material developments with respect thereto.

   

  (e)           

  Kineta Patents. Kineta
    shall have the sole right to prepare, file, prosecute and maintain Kineta Sole Patents and Assigned Joint Study Patents, at Kineta’s sole cost and expense. Solely with respect to the Assigned Joint Study Patents, Kineta shall notify GigaGen in writing
    of any significant developments regarding such Patents and provide copies of material communications received from patent authorities and material filings or responses to be delivered to such authorities (to the extent practicable, reasonably in
    advance of the anticipated filing or response date) with respect thereto.

   

  (f)           

  CREATE Act. It is the
    intention of the Parties that this Agreement is a “joint research agreement” as that phrase is defined in 35 U.S.C. §102(c) as amended by the Cooperative Research and Technology Enhancement (CREATE) Act, including the provisions of 35 U.S.C.
    §102(b)(2)(c), and the Parties agree to cooperate and to take reasonable actions to maximize the protections available for the Licensed Patents, Joint Patents, Kineta Sole Patents and Assigned Joint Study Patents.

   

  6.4          Enforcement.

   

  (a)           

  Notification. If either
    Party becomes aware of any (i) existing or threatened infringement, anywhere in the world, of any Licensed Patent, Joint Patent or Assigned Joint Study Patent, which infringement involves (A) the manufacture, use, sale, import or offer for sale of any
    Licensed Product or (B) the filing of a BLA by a Third Party for a product that names a Licensed Product as a reference product (or similar filing in a country other than the U.S.) or (ii) declaratory judgment action by a Third Party in connection with
    any infringement described in the preceding clause (i) alleging the invalidity, unenforceability or non-infringement of a Licensed Patent, Joint Patent or Assigned Joint Study Patent (collectively (i) and (ii), a “Product Infringement”), such
    Party shall promptly notify the other Party in writing to that effect.

   

  
    18 

    
      
 

  

   

  (b)           

  Enforcement Rights. From
    and after the Option Exercise Date, Kineta shall have the first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in, or to defend against, any Product Infringement of a Licensed
    Patent, at Kineta’s cost and expense. If Kineta does not, within one hundred eighty (180) days after its receipt or delivery of notice under Section 6.4(a), commence a suit to enforce the applicable Patents, take other action to terminate such Product
    Infringement or initiate a defense against such Product Infringement, then upon Kineta’s prior written consent, which shall not be unreasonably withheld or delayed, GigaGen shall have the right, but not the obligation, to commence such a suit or take
    such an action or defend against such Product Infringement of a Licensed Patent, in the Territory at its own cost and expense. In such event, Kineta shall take appropriate actions in order to enable GigaGen to commence a suit or take the actions set
    forth in the preceding sentence. GigaGen shall not settle any such suit or action in any manner that would negatively impact the Licensed Patents or that would limit or restrict the ability of Kineta to sell Licensed Products anywhere in the Territory
    without the prior written consent of Kineta. Kineta shall have the right, at its own expense, to be represented in any such suit by counsel of its own choice.

   

  (c)           

  Collaboration. Each Party
    shall cooperate with and provide to the Party enforcing any such rights under Section 6.4(b) reasonable assistance in such enforcement, at such enforcing Party’s request and expense. GigaGen further agrees to join, at Kineta’s expense, any such action
    brought by Kineta under Section 6.4(b) as a party plaintiff if required by applicable law to pursue such action. The enforcing Party under Section 6.4(b) shall keep the other Party regularly informed of the status and progress of such enforcement
    efforts, and shall reasonably consider the other Party’s comments on any such efforts. Kineta may exercise any of its rights pursuant to this Section 6.4 through an Affiliate or Sublicensee.

   

  (d)           

  Expenses and Recoveries. The Party bringing or defending a claim, suit or action under Section 6.4(b) shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or
    action. If such Party recovers monetary damages in such claim, suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation
    of expenses of internal counsel), and any remaining amounts will be retained by Kineta, except that any such amounts attributable to lost sales of Licensed Products shall be included in Net Sales subject to the royalty payment by Kineta to GigaGen
    pursuant to Section 4.5.

   

  (e)            

  Enforcement of Kineta Patents, Joint Patents and Assigned Joint Study Patents. As between the Parties, Kineta shall have the sole right, but not the obligation, to bring an appropriate suit or other action
    against any person or entity engaged in, or to defend against, any Product Infringement of any Kineta Sole Patents, Joint Patents or Assigned Joint Study Patents, at Kineta’s expense and as it reasonably determines appropriate.

   

  
    19 

    
      
 

  

   

  (f)            Other Infringement Actions.

   

  (i)             As between the Parties, GigaGen shall
    have the sole right to bring an appropriate suit or other action to enforce the Licensed Patents against any infringement that is not a Product Infringement, at its own expense and as it reasonably determines appropriate.

   

  (ii)           As between the Parties, Kineta shall have
    the sole right to bring an appropriate suit or other action to enforce the Kineta Sole Patents or Assigned Joint Study Patents against any infringement that is not a Product Infringement, at its own expense and as it reasonably determines appropriate.

   

  (iii)          Each Party shall notify the other promptly
    after becoming aware of any alleged or threatened infringement by a Third Party of any Joint Patent that is not a Product Infringement. The Parties will confer promptly thereafter to determine a course of action, and if the Parties fail to agree, each
    Party shall have the right to enforce such Joint Patent against such infringement.

    Confidentiality

   

  7.1          Confidentiality. Each Party agrees that,
    during the Term and for a period of ten (10) years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement (which includes the exercise of any
    rights or the performance of any obligations hereunder) any Confidential Information furnished to it by the other Party pursuant to this Agreement, except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the
    Parties. The foregoing confidentiality and non-use obligations shall not apply to any portion of the other Party’s Confidential Information that the receiving Party can demonstrate by competent written proof:

  was already known to the
    receiving Party or its Affiliate, other than under an obligation of confidentiality, at the time of disclosure by the other Party;

   

  (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 receiving Party in breach of this Agreement;

   

  (d)      

  was disclosed to the receiving Party or its Affiliate by a Third Party who has a legal right to make such disclosure and who did not obtain such information directly or indirectly from the other Party; or

   

  (e)      

  was independently discovered or developed by the receiving Party or its Affiliate without aid, application or use of the other Party’s Confidential Information, as evidenced by a contemporaneous writing.

   

  
    20 

    
      
 

  

   

  7.2          Authorized Disclosure. Notwithstanding the
    obligations set forth in Section 7.1, a Party may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent:

   

  (a)           such disclosure is reasonably necessary to
    (i) its employees, agents, consultants and contractors on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case, the disclosees are bound by written obligations
    of confidentiality and non-use consistent with those contained in this Agreement; or (ii) actual or potential investors, acquirors, licensees and other financial or commercial partners solely for the purpose of evaluating or carrying out an actual or
    potential investment, acquisition, collaboration or license, provided that in each such case such recipients are bound by confidentiality and non-use obligations at least as stringent as those contained in the Agreement and with a term of no less than
    five (5) years; or

   

  (b)           such disclosure is reasonably necessary to
    comply with applicable Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or order; provided that the Party subject to such Laws shall promptly notify the other Party of such required
    disclosure and shall use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure.

   

  7.3          Publicity; Term of Agreement.

   

  (a)           The Parties agree that the material terms of
    this Agreement are the Confidential Information of both Parties subject to the special authorized disclosure provisions set forth in this Section 7.3 or Section 7.2.

   

  (b)           Notwithstanding any contrary terms in the
    MTA, Kineta shall have the sole right after the Option Exercise Date to issue a press release or make any other public disclosure (including a scientific publication or presentation) pertaining to any results achieved in connection with its activities
    under this Agreement or the MTA, at any time in its sole discretion, without any review or approval rights by GigaGen. Prior to the Option Exercise Date, GigaGen will be consulted about any press release or any other public disclosure pertaining to any
    results achieved in connection with Kineta’s activities under this Agreement or the MTA, with enough time to provide feedback prior to publication.

   

  (c)           Subject to Section 7.3(b), if either Party
    desires to make any public announcement concerning the material terms of this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (except as
    otherwise provided herein), except that in the case of a press release or governmental filing required by Law, the disclosing Party shall provide the other Party with such advance notice as it reasonably can and shall not be required to obtain approval
    therefor. Each such press release shall contain appropriate references to the other Party if so requested. A Party commenting on such a proposed press release shall provide its comments, if any, within three (3) business days after receiving the press
    release for review. Neither Party shall be required to seek the permission of the other Party to repeat any information that has already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 7.3(c), provided such
    information remains accurate as of such time.

   

  
    21 

    
      
 

  

   

  (d)           The Parties acknowledge that either or both
    Parties may be obligated to file under applicable Laws a copy of this Agreement with the U.S. Securities and Exchange Commission or other Governmental Authorities. Each Party shall be entitled to make such a required filing, provided that it requests
    confidential treatment of the commercial terms and sensitive technical terms hereof and thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party will provide the other Party
    with a copy of this Agreement marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s reasonable comments thereon to the extent consistent with the legal
    requirements, with respect to the filing Party, governing disclosure of material agreements and material information that must be publicly filed.

    Grifols, S.A. The GigaGen Antibodies were generated solely by GigaGen using GigaGen’s solely-owned discovery platform and were not acquired from or contributed to by a Third Party. GigaGen has the full and legal rights and authority to grant to Kineta
    the exclusive licenses and option set forth in Sections 2.1 and 2.2 hereof;

   

  
    22 

    
      
 

  

   

  (b)           

  Exhibit A. Exhibit A, as amended by the Parties within three (3) days after the Option Exercise Date, is an accurate listing by owner, inventor(s), serial number, country and status of all patents
    and patent applications owned or controlled by GigaGen or its Affiliates as of the Option Exercise Date that are necessary or useful for the research, development, manufacture or commercialization of Licensed Antibodies and Licensed Products;

   

  (c)

  (d)           

  Validity. There is no
    fact or circumstance known to GigaGen as of the Option Exercise Date that would cause GigaGen to reasonably conclude that any of the issued patents in the Licensed Patents is invalid or unenforceable, or that any patent application in the Licensed
    Patents will be invalid or unenforceable upon issuance;

   

  (e)           

  Notice of Infringement.
    It has not received any notice or threat from any Third Party asserting or alleging, nor does GigaGen have any knowledge of any basis for any assertion or allegation, that any research, manufacture or development of GigaGen Antibodies by GigaGen prior
    to the Effective Date infringed or would infringe the intellectual property rights of such Third Party;

   

  (f)            

  Notice of Misappropriation.
    It has not received any notice or threat from any Third Party asserting or alleging, and there is no basis for any assertion or allegation, that any research, manufacture or development of GigaGen Antibodies by GigaGen prior to the Effective Date
    misappropriated the intellectual property rights of such Third Party;

   

  (g)           

  No Conflicts. GigaGen has

    rights granted to Kineta under this Agreement, or that would otherwise materially conflict with or adversely affect Kineta’s rights under this Agreement;

   

  (h)           

    

  Third Party Infringement.
    To GigaGen’s knowledge, no Third Party is infringing or has infringed any Patents or has misappropriated any Information, in each case, licensed to Kineta hereunder and related to the GigaGen Antibodies;

   

  (i)            

  Inventor Assignments. All
    inventors of GigaGen that participated in the discovery, generation or development of any GigaGen Antibodies or the creation or generation of any Assigned Joint Study IP are subject to valid and enforceable employment and/or invention assignment
    agreements assigning to GigaGen each such inventor’s entire right, title and interest in and to the relevant intellectual property or Information created, developed or generated by such person;

   

  
    23

    course of the discovery, generation or development of any GigaGen Antibody, GigaGen has not, and to the knowledge of GigaGen, no employee, consultant or representative of GigaGen or any Third Party acting on behalf of GigaGen (in each case, as
    applicable) has, used any employee, consultant or representative that is debarred by any Regulatory Authority or is the subject of debarment proceedings by any Regulatory Authority;

   

  (m)          

  Public Disclosure. The
    sequences of the GigaGen Antibodies have not been publicly disclosed as of the Effective Date. GigaGen will not disclose (i) the sequence of any GigaGen Antibody prior to the Option Exercise Date or (ii) the sequence of any Selected Antibody on and
    after the Option Exercise Date.

   

  (n)           

  No Other Agreements.
    Except for the Trianni Agreement, GigaGen has not entered into any agreement with a Third Party pursuant to which GigaGen is obligated to make any payments to such Third Party arising from or in connection with the development, manufacture,
    commercialization or other exploitation of the GigaGen Antibodies, Licensed Antibodies or Licensed Products by or on behalf of Kineta hereunder, and GigaGen shall not enter into any such agreement without obtaining the prior written approval of Kineta;
    and

  Article 9

    

    Indemnification

   

  9.1          Indemnification by Kineta. Kineta shall
    defend, indemnify, and hold GigaGen and its Affiliates and their respective officers, directors, employees, and agents (the “GigaGen Indemnitees”) harmless from and against damages or other amounts payable to a Third Party claimant, as well as
    any reasonable attorneys’ fees and costs of litigation incurred by such GigaGen Indemnitees, resulting from any claims, suits, proceedings or causes of action brought by such Third Party (collectively, “Claims”) against such GigaGen Indemnitee
    to the extent arising from or based on (a) the development, manufacture or commercialization of Licensed Antibodies and Licensed Products by or on behalf of Kineta or its Affiliates or Sublicensees, (b) the breach of any of Kineta’s obligations,
    representations or warranties under this Agreement, or (c) the willful misconduct or negligent acts of Kineta, its Affiliates, or the officers, directors, employees or agents of Kineta or its Affiliates. The foregoing indemnity obligation shall not
    apply to the extent that (i) the GigaGen Indemnitees fail to comply with the indemnification procedures set forth in Section 9.3 and Kineta’s defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from or is based on any
    activity set forth in Section 9.2(b) or 9.2(c) for which GigaGen is obligated to indemnify the Kineta Indemnitees under Section 9.2.

   

  9.2          Indemnification by GigaGen. GigaGen shall
    defend, indemnify, and hold Kineta and its Affiliates and their respective officers, directors, employees, and agents (the “Kineta Indemnitees”) harmless from and against damages or other amounts payable to a Third Party claimant, as well as any
    reasonable attorneys’ fees and costs of litigation incurred by such Kineta Indemnitees, resulting from any Claims against such Kineta Indemnitee to the extent arising from or based on (a) the research, development and manufacture of Licensed Antibodies
    and the research, development, manufacture and commercialization of Non-Licensed Antibodies by or on behalf of GigaGen or its Affiliates or licensees, (b) the breach of any of GigaGen’s obligations, representations or warranties under this Agreement,
    or (c) the willful misconduct or negligent acts of GigaGen, its Affiliates, or the officers, directors, employees or agents of GigaGen or its Affiliates. The foregoing indemnity obligation shall not apply to the extent that (i) the Kineta Indemnitees
    fail to comply with the indemnification procedures set forth in Section 9.3 and GigaGen’s defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from or is based on any activity set forth in Section 9.1(b) or 9.1(c) for
    which Kineta is obligated to indemnify the GigaGen Indemnitees under Section 9.1.

   

  9.3          Procedure. To be eligible to be indemnified
    as described in this Article 9, each person or entity seeking to be indemnified (each, an “Indemnitee”) shall provide the indemnifying Party with prompt notice of any claim (with a description of the claim and the nature and amount of any such
    loss) giving rise to the indemnification obligation pursuant to Section 9.1 or 9.2, as the case may be, and the exclusive ability to defend such claim (with the reasonable cooperation of Indemnitee(s)). Each Indemnitee shall have the right to retain
    its own counsel, at its own expense, if representation by the counsel of the indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnitee(s) and the Indemnifying Party. Neither the Indemnitee(s) nor
    the indemnifying Party shall settle or consent to the entry of any judgment with respect to any claim for losses for which indemnification is sought without the prior written consent of the other (not to be unreasonably withheld or delayed); provided
    however, that the indemnifying Party shall have the right to settle or compromise any claim for losses without such prior written consent if the settlement or compromise provides for a full and unconditional release of the Indemnitee(s) and is not
    materially prejudicial to any Indemnitee’s rights.

   

  
    25 

    
      
 

  

   

  9.4          Insurance. Each Party shall procure and
    maintain insurance consistent with normal business practices of prudent companies similarly situated. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification
    obligations under this Article 9. Each Party shall provide the other Party with written evidence of such insurance upon request. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation or
    non-renewal of such insurance.

   

  Article 10

    

    Term; Termination

   

  10.1        Term. This Agreement shall become effective
    on the Effective Date and, unless earlier terminated pursuant to this Article 10, shall remain in effect on a Licensed Product-by-Licensed Product and country-by-country basis, until the expiration of the Royalty Term for such Licensed Product in such
    country (the “Term”); provided that this Agreement will expire upon expiration of the Option Term if Kineta does not provide the Option Exercise Notice before the expiration of the Option Term. Upon the expiration of the Royalty Term for a
    Licensed Product in a particular country, the licenses granted by GigaGen to Kineta under Section 2.1 with respect to such Licensed Product and such country shall become fully-paid, royalty free, perpetual and irrevocable.

   

  10.2        Termination by Kineta. Kineta may terminate
    this Agreement at will upon thirty (30) days prior written notice to GigaGen.

   

  10.3        Termination for Material Breach.

   

  (a)           Breach. Subject to Section 10.3(b), each
    Party shall have the right to terminate this Agreement upon written notice to the other Party if such other Party materially breaches this Agreement and, after receiving written notice from the non-breaching Party identifying such material breach in
    reasonable detail, fails to cure such material breach within ninety (90) days from the date of such notice; provided that if such breach is not reasonably capable of cure within such ninety (90)-day period, the breaching Party may submit a reasonable
    cure plan prior to the end of such ninety (90)-day period, in which case the other Party shall not have the right to terminate this Agreement for so long as the breaching Party is using diligent efforts to implement such cure plan.

   

  (b)           Disputed Breach. If the alleged breaching
    Party disputes in good faith the existence or materiality of a breach specified in a notice provided by the other Party in accordance with Section 10.3(a), and such alleged breaching Party provides the other Party notice of such dispute within such
    ninety (90)-day period, then the non-breaching Party shall not have the right to terminate this Agreement under Section 10.3(a) unless and until the arbitrators, in accordance with Article 11, have determined that the alleged breaching Party has
    materially breached the Agreement and such Party fails to cure such breach within ninety (90) days following such arbitrators’ decision. It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this
    Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.

   

  
    26 

    
      
 

  

   

  10.4        Effects of Termination. 

   

  (a)           Accrued Obligations; Survival. Termination or
    expiration of this Agreement for any reason shall not release a Party from any liability or obligation that already has accrued prior to such expiration or termination, nor affect the survival of any provision hereto to the extent it is expressly
    stated to survive such termination. The following provisions shall survive any expiration or termination of this Agreement for a period of time specified therein, or if not specified, then they shall survive indefinitely: Articles 1, 7, 9, 11 and 12
    and Sections 2.5, 2.6, 5.4, 5.5, 5.6, 6.1, 6.2, 8.3 and 10.4.

   

  (b)           Sublicense Survival. Upon termination of this
    Agreement by GigaGen pursuant to Section 10.3, any sublicense granted by Kineta under this Agreement shall survive as a direct license between GigaGen and such Sublicensee on the same terms and conditions as those set forth in this Agreement, to the
    extent applicable to the rights granted by Kineta to such Sublicensee, provided that such sublicense was granted in accordance with the terms of Section 2.2(b) and that such Sublicensee is in compliance with the terms of the sublicense agreement and
    agrees to comply with all applicable terms of this Agreement.

   

  (c)           Continued License.  If Kineta has the right
    to terminate this Agreement pursuant to Section 10.3, then in lieu of termination, Kineta shall have the right to keep this Agreement in effect and to elect the following consequences upon written notice to GigaGen: (i) the diligence obligations set
    forth in Section 3.2 shall terminate and (ii) the milestone payments set forth in Sections 4.3 and 4.4 and royalty payments in Section 4.5 shall, with respect to payments accrued after such election, be reduced by fifty percent (50%), and Kineta may
    offset such payment obligations by any contract damages that are determined to be due to Kineta pursuant to Article 11.

   

  Article 11 

   

  Governing Law; Dispute Resolution

   

  11.1        Governing Law. This Agreement shall be
    governed by, and all disputes arising under or in connection with this Agreement shall be resolved in accordance with, the laws of the State of Delaware, without giving effect to any conflicts of laws principles that would require the application of
    other law.

   

  11.2        Dispute Resolution. The Parties recognize
    that disputes as to matters arising out of or in connection with this Agreement, including any question regarding its formation, existence, validity or termination, or either Party’s rights or obligations hereunder (collectively, “Disputes”) may
    arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of such Disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties
    agree to follow the procedures set forth in this Article 11 to resolve any such Dispute if and when it arises.

   

  
    27 

    
      
 

  

   

  11.3        

  Resolution by Executives. If any Dispute arises, either Party may refer such Dispute to the Chief Executive Officer of GigaGen and the Chief Executive Officer of Kineta, who shall meet in person
    or by telephone within thirty (30) days after such referral to attempt in good faith to resolve such Dispute. If such matter cannot be resolved by discussion of such officers within such thirty (30)-day period (as may be extended by mutual written
    agreement), such Dispute shall be resolved in accordance with Section 11.4. The Parties acknowledge that discussions between the Parties to resolve Disputes are settlement discussions under applicable rules of evidence and without prejudice to either
    Party’s legal position.

   

  11.4        Arbitration.

   

  (a)           

  AAA. Any Dispute that is not resolved through negotiations under Section 11.3 shall be finally settled by binding arbitration by three (3) arbitrators pursuant to the then-current Commercial Arbitration
    Rules of the American Arbitration Association (“AAA Rules”), except where they conflict with this Section 11.4, in which case this Section 11.4 shall control. Each Party shall nominate one arbitrator and the two party-nominated arbitrators shall
    nominate the third arbitrator, who shall serve as the presiding arbitrator, within fifteen (15) days after the second arbitrator’s appointment. At the request of a Party, the arbitral tribunal shall have the discretion to order the disclosure of
    specified documents by the Parties. Such a request shall identify the document(s) with a reasonable degree of specificity and establish the relevance of the document(s) to the arbitration.

   

  (b)           

  Seat; Language. The seat,
    or legal place, of arbitration shall be Seattle, Washington. The language of the arbitration shall be English. The Parties acknowledge that this Agreement evidences a transaction involving interstate commerce. Notwithstanding Section 11.1 with respect
    to the applicable substantive Law, any arbitration conducted pursuant to the terms of this Agreement shall be governed by the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16 (the “Federal Arbitration Act”), to the exclusion of any inconsistent
    state laws.

   

  (c)      

  Relief. Except as otherwise specifically limited in this Agreement, the arbitral tribunal shall have the power to grant any remedy or relief that it deems appropriate, whether provisional or final,
    including injunctive relief. Each Party retains the right to apply to any court of competent jurisdiction for interim and/or conservatory measures, including pre-arbitral attachments or preliminary injunctions, and any such request shall not be deemed
    incompatible with, or a waiver of, this agreement to arbitrate. The arbitration award shall be final and binding on the Parties, and the Parties undertake to carry out any award without delay. Judgment on the award may be entered in any court of
    competent jurisdiction.

   

  (d)     

  Costs. Each Party shall bear its own legal fees. The arbitrators shall assess their costs, fees and expenses against the Party losing the arbitration unless they believe that neither Party is the clear
    winner, in which case the arbitrators shall divide such fees, costs and expenses according to their discretion. The arbitrators, in the arbitrators’ discretion, may award reimbursement of attorney’s fees to the prevailing Party.

  (e)           

  Confidentiality. The
    existence and content of the arbitral proceeding, including any rulings or award, shall be kept confidential by the Parties and the arbitrators except to the extent (i) required by applicable Law; (ii) required to protect or pursue a legal right; (iii)
    required to enforce or challenge an award; or (iv) approved by written consent of the Parties. Notwithstanding anything to the contrary herein, either Party may disclose matters relating to the arbitration or the arbitral proceedings where necessary
    for the preparation or presentation of a claim or defense in such arbitration. The arbitrators shall issue appropriate protective orders to safeguard each Party’s Confidential Information.

   

  (f)      

  Timing. The award shall be rendered within eighteen (18) months of the appointment of the arbitral tribunal, unless the Parties jointly request an extension or the arbitral tribunal determines, in a
    reasoned decision, that the interest of justice or the complexity of the case requires that such limit be extended.

   

  (g)        

  Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

   

  (h)     

  Patent and Trademark Disputes. Any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any patents or trademarks shall be submitted to a court of competent
    jurisdiction in the country in which such patent or trademark rights were granted or arose.

    General Provisions

   

  12.1        Rights in Bankruptcy. All licenses and other
    rights granted under or pursuant to this Agreement by GigaGen are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S.
    Bankruptcy Code. The Parties agree that Kineta, as licensee of certain rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the
    commencement of a bankruptcy proceeding by or against GigaGen under the U.S. Bankruptcy Code, Kineta shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property licensed to Kineta and all embodiments
    of such intellectual property, which, if not already in Kineta’s possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon Kineta’s written request therefor, unless GigaGen elects to continue to
    perform all of its obligations under this Agreement or (b) if not delivered under clause (a), following the rejection of this Agreement by GigaGen upon written request therefor by Kineta.

    be given under this Agreement shall be in writing, shall specifically refer to this Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in
    accordance with this Section 12.2, and shall be deemed to have been given for all purposes when received, if hand-delivered or sent by reputable courier service.

  12.3        

  Force Majeure. No Party shall be liable for any delay or failure of performance to the extent such delay or failure is caused by circumstances beyond its reasonable control and that by the
    exercise of due diligence it is unable to prevent, provided that the Party claiming excuse uses its commercially reasonable efforts to overcome the same.

   

  12.4        

  Performance by Affiliates.
    Each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to
    comply with the provisions of this Agreement in connection with such performance.

   

  12.5        

  Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the
    purposes and intent of this Agreement.

   

  12.6        

  Entirety of Agreement. This Agreement, including its Exhibits, sets forth the entire agreement and understanding of the Parties relating to the subject matter contained herein and supersedes all
    prior discussions and agreements between them (including the Confidentiality Agreement, which is hereby terminated) related to such subject matter. The Agreement may be amended only by a written instrument signed by authorized representatives of each
    of the Parties.

   

  12.7        

    

  Non-Waiver. The failure of
    a Party in any one or more instances to insist upon strict performance of any of the terms and conditions of this Agreement shall not be construed as a waiver or relinquishment, to any extent, of the right to assert or rely upon any such terms or
    conditions on any future occasion.

   

  
    30 

    
      
 

  

   

  12.8        

  Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind or
    commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

   

  12.9        

  Severability. If any one or
    more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to
    invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement
    may be realized.

   

  12.10      

  Assignment. Neither Party may assign or transfer this Agreement without the prior written consent of the other, except that a Party may make such an assignment or transfer without the other
    Party’s consent to its Affiliates or to a Third Party successor to substantially all of the business of such Party to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other transaction. Any permitted assignment shall
    be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 12.10 shall be null, void and of no legal effect.

   

  12.11      

  Limitation of Liability. Except FOR indemnity obligatIons in ARTICLE 9 and DAMAGES AVAILABLE FOR breach of ARTICLE 7, in no event shall either Party be
      liable to the other party for incidental, consequential, indirect, punitive or special damages arising out of or related to this Agreement, however caused, under any theory of liability, even if advised of the possibility of such damages. 

   

  12.12      

  No Strict Construction;
      Headings. This Agreement has been prepared jointly by the Parties and shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed
    to have authored the ambiguous provision. The headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular
    Article or Section. Except where the context otherwise requires, the use of any gender shall be applicable to all genders, and the word “or” is used in the inclusive sense (and/or). The term “including” as used herein means including, without limiting
    the generality of any description preceding such term.

   

  12.13      

  Counterparts. This
    Agreement may be executed in one or more counterparts, each of which shall be an original and all of which shall constitute together the same document. Signatures provided by facsimile transmission or in Adobe Portable Document Format (.pdf) sent by
    electronic mail shall be deemed to be original signatures.
