industry standards, guidelines and best practices, to conduct such clinical trials and in compliance with all applicable federal, state and local laws, regulations and guidances; and further provided COH and LA Cell enter into a mutually agreed upon
clinical trial agreement.

(collectively, the “Proprietary Sublicenses”) without the consent of COH, which sublicenses shall be effective immediately upon execution provided that Licensee provides written notice of any such sublicense within 5 days of entry
into such sublicense. 
 3.3.2 Non-Proprietary Sublicenses. 

(a) The Parties shall establish a joint licensing steering committee (the “JLSC”) that will be responsible for and coordinate

Licensee’s rights hereunder shall be consistent with this Agreement. A true and complete copy of each sublicense of Licensee’s rights hereunder, as well as any amendment thereto, shall be delivered to COH promptly following the effective
date of each such sublicense or amendment. 
 3.4 Effect of Termination on Sublicenses. 

3.4.1 In the event that this Agreement terminates at any time for any reason, each sublicense validly granted hereunder which is in good

aggregate of other non- sale/royalty-based consideration due from Sublicensee, and (3) the other material terms and conditions of the sublicense are materially no less favorable to COH than the corresponding terms (excluding the stock grant due
pursuant to Section 4.3, below) of this Agreement, or 
 [B] The terms and conditions of the sublicense had been approved by
COH prior to its having been entered into by Licensee and the Sublicensee, such approval having been considered by COH expeditiously and not conditioned on the payment by Licensee of any additional consideration. 

3.5 Documentation of Licensed Services. Licensee and its Sublicensees shall provide Licensed Services only pursuant to one or
more written agreements which set forth, in reasonable detail, all consideration due to Licensee for the provision of such services. Licensee shall provide a true and complete copy of each such agreement to COH promptly following the effective date
of such agreement.

4.3 Stock Grant; COH Representations and Warranties. 

4.3.1 Concurrently with the execution of this Agreement, Licensee will issue to COH or its designees stock certificates evidencing 2,648,948
validly issued, fully-paid, non-assessable shares of Class C Common Stock (the “Shares”). 
 4.3.2 COH understands that
neither the COH Shares nor the shares of Class A Common Stock issuable upon conversion of the COH Shares (including based on any adjustment to the conversion rate pursuant to the Charter) (the “Conversion Shares”) have been registered
under the Act. COH also understands that the COH Shares are being offered and sold pursuant to an exemption from registration contained in the Act based in part upon COH’s representations contained in the Agreement. COH hereby represents and
warrants as follows: 
  

	[*]	Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portion 


  
 16 








 (a) COH has substantial experience in evaluating and investing in private placement transactions
of securities in companies similar to the Licensee so that it is capable of evaluating the merits and risks of its investment in the Licensee and has the capacity to protect its own interests. COH must bear the economic risk of this investment
indefinitely unless the COH Shares (or the Conversion Shares) are registered pursuant to the Act, or an exemption from registration is available. COH understands that the Licensee has no present intention of registering the COH Shares, the
Conversion Shares or any shares of its Common Stock. COH also understands that there is no assurance that any exemption from registration under the Act will be available and that, even if available, such exemption may not allow COH to transfer all
or any portion of the COH Shares or the Conversion Shares under the circumstances, in the amounts or at the times COH might propose. 
 (b)
COH is acquiring the COH Shares and the Conversion Shares for COH’s own account for investment only, and not with a view towards their distribution. 

(c) COH represents that by reason of its, or of its management’s, business or financial experience, COH has the capacity to protect its
own interests in connection with the transactions contemplated in this Agreement. 
 (d) COH represents that it is an accredited investor
within the meaning of Regulation D under the Act. 
 (e) COH has had an opportunity to discuss the Licensee’s business, management and
financial affairs with directors, officers and management of the Licensee. COH has also had the opportunity to ask questions of and receive answers from, the Licensee and its management regarding the terms and conditions of this investment. 

(f) COH acknowledges and agrees that the COH Shares, and, if issued, the Conversion Shares are “restricted securities” as defined in
Rule 144 promulgated under the Act as in effect from time to time and must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available. COH has been advised or is aware of the
provisions of Rule 144, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the
Licensee, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding specified limitations. 

  
 17 








 4.4 Development Milestone Payments. Within 30 days after the occurrence of
each “Development Milestone Event” set forth below whether achieved by Licensee, its Affiliate or a Sublicensee, Licensee shall pay COH or its designee the amount indicated below for each of the first
eight (8) antibodies or antibody-related products Covered by the Patent Rights in the Field to enter clinical trials: 
  

					
	 Development Milestone Event
	  	 Amount Due
	 
	 #1. Upon the dosing of the first patient in a Phase 1 Clinical Trial for
each of the first eight (8) antibodies or antibody-related products within the scope of the Patent Rights in the Field
	  	$	*	  
	 #2. Upon the dosing of the first patient in a Phase 2 Clinical Trial for each
of the first eight (8) antibodies or antibody-related products within the scope of the Patent Rights in the Field
	  	$	*	  
	 #3. . Upon the dosing of the first patient in a Phase 3 Clinical Trial for
each of the first eight (8) antibodies or antibody-related products within the scope of the Patent Rights in the Field
	  	$	*	  
	 #4. Upon FDA Marketing Approval of each of the first eight (8) antibodies or
antibody-related products within the scope of the Patent Rights in the Field
	  	$	*	  
	 #5. Upon Marketing Approval in any jurisdiction outside of the U.S. Approval of
each of the first eight (8) antibodies or antibody-related products within the scope of the Patent Rights in the Field
	  	$	*	  

 In the event that any development milestone event is met with respect to a specific antibody or antibody-related
product prior to the satisfaction of any prior milestone event with respect to the applicable antibody or antibody-related product, then Licensee shall also pay the amount due for occurrence of all prior milestone events not previously paid
upon meeting the applicable development milestone (e.g., if a patient is dosed in a Phase 3 Clinical Trial prior to dosing of a first patient in a Phase 2 trial, Licensor shall pay COH $* million upon dosing the first patient in a Phase 3
Trial). For clarity, only one payment will be due per antibody or antibody-related product per Development Milestone Event. For example, if a particular antibody receives Marketing Approval in Canada and Mexico, only one (1) $* payment shall be
due to COH.

 4.5 Sales Milestone Payments. Within sixty (60) days following the end of each
License Year that Licensee its Affiliate or a Sublicensee achieves the “Sales Milestone Event” set forth below, Licensee shall pay COH or its designee the amount indicated below for each of the first eight (8) antibodies or
antibody-related products Covered by the Patent Rights obtain Marketing Approval:

 4.6 Royalties. 

4.6.1 Net Sales. Licensee shall pay to COH or its designee royalties in an amount equal to *% of Net Sales of Licensed Products
and Licensed Services, for clarity, including Net Sales by Affiliates. Royalties shall be paid on a Licensed Product-by-Licensed Product, Licensed Service-by-Licensed Service and country-by-country basis until the expiration in each country of
the last to expire of the Valid Claims in such country Covering Licensed Products or Licensed Services. 
 4.6.2 Sublicensee Net
Sales. Licensee shall pay to COH or its designee royalties in an amount equal to (i) *% of Sublicensee Net Sales of Licensed Products and Licensed Services if Licensee and Sublicensee (other than a Sublicensee that is an Affiliate of
Licensee) enter a sublicense agreement prior to the dosing of the first patient in a Phase 3 Clinical Trial for the applicable category of human disease in the Field; and (ii) *% of Sublicensee Net Sales of Licensed Products and Licensed Services if
Licensee and Sublicensee (other than a Sublicensee that is an Affiliate of Licensee) enter a sublicense agreement after the dosing of the first patient in a Phase 3 Clinical Trial for the applicable category of human disease in the
Field. Royalties shall be paid on a Licensed Product-by-Licensed Product, Licensed Service-by-Licensed Service and country-by-country basis until the expiration in each country of the last to expire of the Valid Claims in such country Covering
Licensed Product or Licensed Service. 
  

	[*]	Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portion 


  
 19 








 For clarity, royalties based on sales made by Affiliates shall be paid only by Licensee and only
pursuant to Section 4.6.1, and neither Licensee nor any Affiliate shall have an obligation to pay royalties under this Section 4.6.2 based on sales of Licensed Products or Licensed Services made by an Affiliate of Licensee. In no event shall
royalties be due under both Section 4.6.1 and Section 4.6.2 with respect to the same unit sale. 
 4.7 Sublicense
Revenues. Licensee shall pay to COH a percentage of all Sublicense Revenues within sixty (60) days after payment is received from the relevant Sublicensee, determined as follows: 

4.7.1 *% of Sublicense Revenues from those Proprietary Sublicenses granted prior to the dosing of the first patient in a Phase 2 Clinical
Trial, 
 4.7.2 *% of all Sublicense Revenues from those Proprietary Sublicenses granted after dosing of the first patient in a Phase 2
Clinical Trial but prior to dosing of the first patient in a Phase 3 Clinical Trial, 
 4.7.3 *% of all Sublicense Revenues from those
Proprietary Sublicenses granted after dosing of the first patient in a Phase 3 Clinical Trial. 
 4.7.4 *% of all Sublicense Revenues
received in connection with Non-Proprietary Sublicenses. 
 If Sublicense Revenues are not in cash or cash equivalents, the percentage share payable to COH
pursuant to this Section 4.7 shall be due, in COH’s sole discretion, either in kind or in its cash equivalent. For clarity, with respect to a particular item of consideration, in the event COH receives the applicable percentage of Sublicense
Revenues from a Sublicensee with respect to such item of consideration, Licensee shall not be obligated to also pay COH a percentage of Sublicense Revenue received with respect to the same item of consideration. 

4.8 Timing of Royalty Payments. Royalty payments due under Section 4.6, above, shall be paid annually within sixty (60)
days following the end of each License Year until the first License Year in which aggregate Net Sales across all Licensed Product and License Services reach $* million. Thereafter, all royalty payments due under Section 4.6 shall be paid in
quarterly installments, within sixty (60) days following the end of each calendar quarter.

Covered by more than one Valid Claim. 
 ARTICLE 5: REPORTS, AUDITS AND FINANCIAL TERMS 

5.1 Royalty Reports. Within 60 days after the end of each calendar quarter in which a royalty payment under Article 4 is
required to be made (the “Royalty Period”), Licensee shall send to COH a report of Net Sales of the Licensed Products and Licensed Services for which a royalty is due, which report sets forth for such calendar quarter the following
information, on a Licensed Product-by-Licensed Product, Licensed Service-by-Licensed Service and country-by-country basis: (i) total Net Sales during the Royalty Period, (ii) total gross sales of Licensed Products and Licensed Services during the
Royalty Period, (iii) the quantity of each Licensed Products sold by Licensee and Licensed Services performed by Licensee for value during the Royalty Period, (iv) the exchange rate used to convert Net Sales from the currency in which they are
earned to United States dollars; and (v) the total royalty payments due. 
 5.2 Additional Financial Terms. 

5.2.1 Currency. All payments to be made under this Agreement shall be made in United States dollars, unless expressly
specified to the contrary herein. Net Sales outside of the United States shall be first determined in the currency in which they are earned and shall then be converted into an amount in United States dollars. All currency conversions shall
use the conversion rate reported by Reuters, Ltd. on the last Business Day of the calendar quarter for which such payment is being determined. 

5.2.2 Payment Method. Amounts due under this Agreement shall be paid in immediately available funds, by means of wire
transfer to an account identified by COH. 
 5.2.3 Withholding of Taxes. Licensee may withhold from payments due to COH
amounts for payment of any withholding tax that is required by law to be paid to any taxing authority with respect to such payments. Licensee shall provide to COH all relevant documents and correspondence, and shall also provide to COH any
other cooperation or assistance on a reasonable basis as may be necessary to enable COH to claim exemption from such withholding taxes and to receive a full refund of such withholding tax or claim a foreign tax credit. Licensee shall give COH
proper evidence from time to time as to the payment of such tax. The Parties shall cooperate with each other in seeking deductions under federal and state tax laws and any double taxation or other similar treaty or agreement from time to time
in force. 
 5.2.4 Late Payments. Any amounts not paid on or before the date due under this Agreement are subject to interest
from the date due through and including the date upon which payment is received. Interest is calculated, over the period between the date due and the date paid, at a rate equal to one and one-half percentage point (1.5%) over the “bank prime
loan” 

  
 21 








 
rate, as such rate is published in the U.S. Federal Reserve Bulletin H.15 or successor thereto on the last Business Day of the applicable calendar quarter prior to the date on which such payment
is due. 
 5.2.5 Blocked Currency. If, at any time, legal restrictions prevent the prompt remittance of part or all
royalties with respect to any country where a Licensed Product is sold or Licensed Service provided, payment shall be made through such lawful means or methods as Licensee may determine. When in any country, the law or regulations prohibit both
the transmittal and deposit of royalties or other payments, Licensee shall continue to report all such amounts, but may suspend payment for as long as such prohibition is in effect. As soon as such prohibition ceases to be in effect, all
amounts that would have been obligated to be transmitted or deposited but for the prohibition, together with accrued interested thereon, shall promptly be transmitted to COH. 

5.3 Accounts and Audit. 

5.3.1 Records. Licensee shall keep, and shall require that each Sublicensee keep, full, true and accurate books of account
containing the particulars of its Net Sales and the calculation of royalties. Licensee shall each keep such books of account and the supporting data and other records at its facilities located at the address set forth in Section 14.7, which
Licensee may change upon change by sending notice to the COH in accordance with Section 14.7, and its Sublicensees shall each keep such books of account and the supporting data and other records at its principal place of business. Such books
and records must be maintained available for examination in accordance with this Section 5.3.1 for four (4) calendar years after the end of the calendar year to which they pertain, and otherwise as reasonably required to comply with GAAP. 

5.3.2 Appointment of Auditor. COH may appoint an internationally- recognized independent accounting firm reasonably
acceptable to Licensee to inspect the relevant books of account of Licensee and its Sublicensees to verify any reports or statements provided, or amounts paid or invoiced (as appropriate), by Licensee or its Sublicensees, provided such accounting
firm has entered into a confidentiality agreement with Licensee that is customary for audits of that nature. 
 5.3.3 Procedures for
Audit. COH may exercise its right to have Licensee’s and its Sublicensees’ relevant records examined by an independent accounting firm, as set forth in Section 5.3.2, only during the four (4) year period during which Licensee is
required to maintain records, no more than once in any consecutive four calendar quarters. Licensee and its Sublicensees are required to make records available for inspection only during regular business hours, only at such place or places where
such records are customarily kept, and only upon receipt of at least 15 days advance notice from COH. All information and materials provided to COH’s accountant are and shall be deemed to be Licensee Confidential Information. 

5.3.4 Audit Report. The independent accountant will be instructed to provide to COH an audit report containing only its
conclusions and methodology regarding the audit, and specifying whether the amounts paid were correct and, if incorrect, the amount of any underpayment or overpayment. 

  
 22 








 5.3.5 Underpayment and Overpayment. After review of the auditor’s report: (i)
if there is an uncontested underpayment by Licensee for all of the periods covered by such auditor’s report, then Licensee shall pay to COH the full amount of that uncontested underpayment, and (ii) if there is an uncontested overpayment for
such periods, then COH shall provide to Licensee a credit against future payments (such credit equal to the full amount of that overpayment), or, if Licensee is not obligated to make any future payments, then COH shall pay to Licensee the full
amount of that overpayment. Contested amounts are subject to dispute resolution under Article 12. If the total amount of any such underpayment (as agreed to by Licensee or as determined under Article 12) exceeds five percent of the amount previously
paid by Licensee for the period subject to audit, then Licensee shall pay the reasonable costs for the audit. Otherwise, all costs of the audit shall be paid by COH. 

ARTICLE 6: LICENSEE COVENANTS 

6.1 Licensee covenants and agrees that: 

6.1.1 in conducting activities contemplated under this Agreement, it shall comply in all material respects with all applicable laws and
regulations including, without limitation, those related to the manufacture, use, labeling importation and marketing of Licensed Products and Licensed Services; 

6.1.2 Licensee will at all times have a sufficient number of Conversion Shares reserved for issuance to COH upon any conversion of the COH
Shares in accordance with the terms of the Charter; 
 6.1.3 Licensee will obtain all authorizations necessary for the issuance of the
Conversion Shares after the Effective Date prior to the issuance of such Conversion Share; 
 6.1.4 Licensee will not, as of immediately
after the closing of any Equity Financing or other event that causes an adjustment to the conversion rate of the COH Shares into Conversion Shares pursuant to the Charter, be in violation or default of any provision of the Charter or Licensee’s
bylaws; and 
 6.1.5 Prior to a Qualified IPO of Licensee, Licensee will obtain COH’s consent, to be given at COH’s sole
discretion, before the consummation of a Change of Control of Licensee. This Section 6.1.5 shall have no effect subsequent to a Qualified IPO of Licensee. 

ARTICLE 7:INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT. 

7.1 Patent Prosecution, Maintenance, Enforcement and Defense. 

7.1.1 Subject to Section 7.4, COH shall be responsible for the preparation, filing, prosecution, maintenance and defense of all Patent Rights,
including in connection with a Validity Action (as defined below), using counsel of its choice. COH will timely provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information
confidential. In addition, COH shall instruct the patent counsel prosecuting Patent Rights to (i) copy Licensee on patent prosecution documents that are received 

  
 23 








 
from or filed with the United States Patent and Trademark Office and foreign equivalent, as applicable; (ii) if requested by Licensee, provide Licensee with copies of draft submissions to the
USPTO prior to filing; and (iii) give reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with respect to the preparation, filing,
prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly represent Licensee unless requested by Licensee and approved by COH, and an appropriate engagement letter
and conflict waiver are in effect).
 7.1.2 COH will not unreasonably refuse to amend any patent application in Patent Rights to include
claims reasonably requested by Licensee to protect the products and services contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent protection with
respect to the Patent Rights, COH shall prepare, file, prosecute and maintain patent applications in such countries and any patents resulting therefrom (and, for the avoidance of doubt, such patent applications and patents shall be deemed included
in the Patent Rights). On a country-by-country and patent-by-patent basis, Licensee may elect to surrender any patent or patent application in Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall relieve
Licensee from the obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the sixty (60) day notice period. Such U.S. or foreign patent application or
patent shall thereupon cease to be a Patent Right hereunder, Licensee shall have no further rights therein and COH shall be free to license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

 7.1.3 Notwithstanding Section 7.1.1 or Section 7.1.2, COH may elect not to file any particular claim or set of claims or in a particular
country, and may elect to abandon prosecution and maintenance of any of the Patent Rights at any time. If COH elects not to file any particular claim or set of claims or in a particular country, or to abandon prosecution and maintenance of any of
the Patent Rights (except in favor a continuation, continuation-in-part or utility application), then COH will provide Licensee with reasonable notice pursuant to Section 14.7 to that effect sufficiently in advance of any deadline for any filing or
submission with respect to any such patent to permit Licensee to carry out such activity. After such notice, provided that Licensee is not in breach or default under this Agreement, Licensee may file, prosecute and maintain each such patent, and
perform such acts as may be reasonably necessary for Licensee or COH to file, prosecute or maintain such patent application or issued patent (as applicable), in its sole discretion and at its sole cost and expense. If Licensee does so elect, then
COH shall provide such full cooperation to Licensee, including the execution and filing of appropriate instruments, as may reasonably be requested to facilitate the transition of such patent activities and Licensee shall have no further obligation
to pay any royalties or other consideration to COH with respect to such patent application or issued patent and related Patent Rights. 

7.1.4 Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of
any of the Patent Rights in or relevant to the Field (“Third Party Infringement”) or in the event of any claim or suit initiated by a Third Party regarding the non-infringement, enforceability, or validity of any Patent Rights (a
“Validity Action”). 

  
 24 








 7.1.5 If infringing activity has not been abated within ninety (90) days following the date the
Third Party Infringement notice takes effect, then Licensee may, following consultation with COH, take any and all action it deems necessary or desirable against any alleged infringer in connection with any Third Party Infringement, provided, that
Licensee has exclusive rights in the category of human disease in the Field applicable to such infringing activity. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this 7.1.5, after
deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Net Sales of Licensed Products and/or Licensed Services in the calendar quarter in which such recovery was received and
royalties shall be due and payable thereon accordingly. Licensee shall not take any position with respect to, or compromise or settle, any Third Party Infringement in any way that would be reasonably likely to directly and adversely affect the
scope, validity, or enforceability of the Patent Rights without the prior written consent of COH (which consent shall not be unreasonably withheld, conditioned or delayed.). 

7.1.6 If required by the applicable court in order for Licensee to maintain standing to prosecute Third Party Infringement and in the event
that Licensee requests, in writing, that COH joins a suit to enforce the Patent Rights against an infringement in the Field, COH agrees to join (and will promptly join) such suit, at Licensee’s expense. If COH is involuntarily joined or
requested to be joined for standing purposes in a suit initiated by Licensee, then the Licensee will pay all reasonable costs incurred by COH arising out of such suit, including but not limited to, all reasonable legal fees of counsel that COH
selects and retains to represent it in the suit. 
 7.1.7 In the event that Licensee declines either to cause such Third Party Infringement
to cease (e.g. by settlement or injunction) or to initiate and thereafter diligently maintain legal proceedings against the infringer other than as part of a mutually agreed upon bona fide strategy, developed with the guidance of outside patent
counsel, to preserve the Patent Rights, COH may, in its sole discretion and at COH’s sole cost, take action against such alleged infringer or in defense of any such Third Party claim. At the request of COH, and if necessary for COH to maintain
standing, Licensee agrees to join a legal proceeding initiated by COH against an infringer of the Patent’s Rights, at COH’s expense. Any recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH
only. 
 7.1.8 COH shall have the right and obligation to take all steps necessary to defend, protect, and to maintain the validity and
enforceability of the Patent Rights in any Validity Action, and subject to Section 7.4, to pay all costs and expenses associated therewith. COH shall not take any position with respect to, or compromise or settle, any Validity Action in any way that
would be reasonably likely to directly and adversely affect the scope, validity, or enforceability of the Patent Rights without the prior written consent of Licensee (which consent shall not be unreasonably withheld, conditioned or delayed.). 

7.2 Trademarks. Licensee shall have the sole right to select, register, maintain and defend all trademarks for use in connection
with the sale or marketing of Licensed Products and 

  
 25 








 
Licensed Services in the Field in the Territory (the “Marks”) and will be responsible for all expenses associated therewith. Licensee shall not, without COH’s prior written
consent, use any trademarks or house marks of COH (including the COH corporate name), or marks confusingly similar thereto, in connection with Licensee commercialization of Licensed Products or Licensed Services under this Agreement in any
promotional materials or applications or in any manner implying an endorsement by COH of Licensee or the Licensed Products or Licensed Services. Licensee shall own all Marks. 

7.3 Challenge to the Patent Rights by Licensee. COH may terminate this Agreement or, notwithstanding Section 3.3, a
sublicense issued hereunder, as applicable, upon written notice to Licensee in the event that Licensee or any of its Affiliates or Sublicensee directly or indirectly asserts a Patent Challenge, provided that any such termination shall be applicable
only with respect to the entity asserting such Patent Challenge and all of such entity’s Affiliates, and that this Agreement shall remain in place and in full force and effect with respect to all other entities. “Patent
Challenge” means any challenge in a legal or administrative proceeding to the patentability, validity or enforceability of any of the Patent Rights (or any claim thereof), including by: (a) filing or pursuing a declaratory judgment action
in which any of the Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the Patent Rights, filing a request for or pursuing a re-examination of any of the Patent Rights (other than with COH’s written
agreement), or voluntarily becoming a party to or pursuing an interference; or (c) filing or pursuing any re-examination, opposition, cancellation, nullity or other like proceedings against any of the Patent Rights; but excluding any challenge
raised as a defense against a claim, action or proceeding asserted by COH against Licensee, its Affiliates, Sublicensees, or any downstream customers or users of any Licensed Products or Licensed Services. In lieu of exercising its rights to
terminate under this Section 7.3, COH may elect upon written notice to increase the payments due under all of Article 4 by one hundred and fifty percent (150%), which election will be effective retroactively to the date of the commencement of the
Patent Challenge. Licensee acknowledges and agrees that this Section 7.3 is reasonable, valid and necessary for the adequate protection of COH’s interest in and to the Patent Rights, and that would not have granted to Licensee the licenses
under those Patent Rights, without this Section 7.3. COH will have the right at any time in its sole discretion to strike this Section 7.3 in its entirety from this Agreement, and COH will have no liability whatsoever as a result of the presence or
absence of this Section 7.3. 
 7.4 Payment of COH Patent Expenses. 

7.4.1 The Parties acknowledge that, prior to the Effective Date, COH provided to Licensee documentation of historic expenses incurred by COH
with respect to the drafting, prosecution and maintenance of the Patent Rights. In consideration of such historic expenditures by COH, Licensee shall reimburse COH for * percent of such expenses within 30 days of the Effective Date, up to $*.

 7.4.2 After the Effective Date, COH shall provide to Licensee an annual invoice and reasonably
detailed documentation with respect to COH’s out-of-pocket expenses incurred with respect to the prosecution, maintenance and defense of the Patent Rights for the previous year, including in connection with any Validity Action. Licensee shall
reimburse COH for * percent of such undisputed expenses within 30 days after receipt of such invoice and documentation. Notwithstanding anything to the contrary in this Agreement, Licensee shall have no obligation to reimburse COH any expenses
incurred pursuant to Section 7.1.7. 
 7.5 Marking. Licensee and its Sublicensees shall mark all Licensed Products and
all materials related to Licensed Services in such a matter as to conform with the patent laws of the country to which such Licensed Products are shipped or in which such products are sold and such Licensed Services performed. 

ARTICLE 8: TERM AND TERMINATION 

8.1 Term and Expiration of Term. The term of this Agreement (the “Term”) shall commence on the Effective Date

transportation, use, distribution, promotion, marketing or sale of Licensed Products or Licensed Services by or on behalf of Licensee, any of its Affiliates or a Sublicensee or any other exercise of rights under this Agreement or pursuant to any
sublicense, or (iii) the negligence, willful misconduct or failure to comply with applicable law by a Licensee Indemnitee or Sublicensee; in each case except to the extent that such Losses are caused directly


  
 32

indemnifying Party may not settle the liability, claim, suit, action or expense, or otherwise admit fault of the other Party or consent to any judgment, without the written consent of the other Party (such consent not to be unreasonably withheld,

 33

Information of the other Party as follows: 
 11.2.1 if required by applicable law, rule, regulation, government requirement and/or court
