(a) the Intellectual Property Updates, (b) the Regulatory Updates, (c) the Clinical Updates, and (d) the Commercial Updates. The Sellers shall also provide the Buyer with such additional information regarding the updates included
in each Quarterly Report as the Buyer may reasonably request from time to time. The Sellers shall prepare and maintain and shall cause their Affiliates and use commercially reasonably efforts to include in any
Out-License a provision requiring any counterparty to any Out-License of the Sellers or the Sellers’ Affiliates to (i) prepare and maintain reasonably complete
and accurate records of the information to be disclosed in each Quarterly Report and (ii) to disclose such information to Seller to enable the disclosures of such information in each Quarterly Report, as contemplated herein. In addition, the
Sellers shall provide the Buyer with a written or telephonic update within ten (10) calendar days following any material development with respect to any prior Clinical Update, Commercial Update, Intellectual Property Update or Regulatory
Update. All Quarterly Reports, and the Confidential Information contained therein, shall be the Confidential Information of Sellers and subject to the obligations of confidentiality set forth in Article 7. The parties understand and agree that if
Sellers are unable to obtain any of the foregoing information from any counterparty to any Out-License (despite using commercially reasonable efforts to include a provision in the relevant Out-License requiring the provision of the same), that Seller will not be obligated to provide such information unless and until Seller is in possession and control of such information, which would be required to be
included by Sellers in the next to occur Quarterly Report, or, in the case of a material development, as soon as reasonably practicable. In addition, Seller my redact from any Quarterly Report and information, the redaction of which is reasonably
required to comply with any obligations of confidentiality to any Third Party or to comply with applicable laws (including those related to patient information and privacy laws). 

Section 5.2    Royalties; Royalty Reports. 

(a)    From and after the First Commercial Sale of any Product or any Related Product and for the duration of the
Term, Kodiak GmbH shall pay to the Buyer the Royalty, exclusive of any Seller Related Charge (but inclusive of any Buyer Related Charge, unless such Buyer Related Charge is levied as a result of an assignment by a Seller pursuant to
Section 9.6, and would not have been levied but for such assignment, in which case the Royalty 

  
 -7- 












 
shall also be exclusive of any Buyer Related Charge), for such calendar quarter promptly, but in any event no later than (i) seventy (70) calendar days after the end of each of the first
three calendar quarters in each calendar year and (ii) ninety (90) calendar days after the end of the last calendar quarter in each calendar year. A late fee of 4% over the Prime Rate will accrue on all unpaid amounts with respect to any
Royalty from the date such obligation was due. The imposition and payment of a late fee shall not constitute a waiver of the Buyer’s rights with respect to such payment default. 

(b)    Simultaneously with the payment of each Royalty, the Sellers shall deliver a written report setting forth in
reasonable detail, (i) the calculation of the Royalty payable to the Buyer for the prior calendar quarter identifying, on a country-by-country basis, the number of
units of the Product or Related Product sold by or on behalf of the Sellers and their Subsidiaries and each counterparty to any Out-License, foreign currency exchange rates used (which shall be rates of
exchange determined in a manner consistent with the Sellers’ method for calculating rates of exchange in the preparation of the Seller’s annual financial statements in accordance with accounting principles generally accepted in the United
States), and a break-down of all permitted deductions from gross sales used to determine Net Sales and the Royalty due to the Buyer and (ii) the cumulative
year-to-date aggregate Net Sales for the Product or Related Product through the end of the prior calendar quarter (the “Royalty Report”). The
Revenue Participation Report shall be in a form agreed by the parties and reasonable acceptable to Buyer and Sellers. 

(c)    On a country-by-country and Product-by-Product or Related-Product-by-Related Product basis, if (i) with respect to a
given Product, if all Patent Rights in such country have expired, lapsed or been rendered invalid or unenforceable, then the Net Sales of such Product in such country shall be reduced by 50% and the Royalty owed to the Buyer shall be calculated
based upon such reduced amount; and (ii) with respect to a given Related Product, if all Related Patent Rights in such country have expired, lapsed or been rendered invalid or unenforceable, then the Net Sales of such Related Product in such
country shall be reduced by 50% and the Royalty owed to the Buyer shall be calculated based upon such reduced amount. 
 
Section 5.3    Disclosures; Public Announcement. The parties will agree on the substance of the initial press release to be made by the Sellers following the execution of this Agreement. After
the issuance of such press release, neither party shall, and each party hereto shall cause its respective Representatives, Affiliates and Affiliates’ Representatives not to issue a press release or other public announcement or otherwise make
any public disclosure with respect to this Agreement or the subject matter hereof without the prior written consent of the other party hereto, except, (i) to make subsequent public disclosures reiterating such information in the press release
(or other information previously approved by the other party for such public release), so long as the information in such release or other public disclosure remains true, correct, and the most current information with respect to the subject matters
set forth therein, (ii) to factually identify the Buyer (or its assignee) as the owner of the Royalty, (iii) to respond to questions in respect of the Buyer (or its assignee) using only the factual information disclosed in the initial
press release (or other information previously approved by the other party for such purpose), and (iv) as may be required by applicable law or stock exchange rule (in which case the party hereto required to make the press release or other
public announcement or disclosure shall allow the other party hereto reasonable time to comment on, and, if applicable, reasonably direct the disclosing party to seek confidential treatment in respect of portions of, such press release or other
public announcement or disclosure in advance of such issuance); provided that, in any case of ((i)-(vi)), Sellers shall not use Buyer’s name primarily for promotional or marketing purposes without the prior written consent of the Buyer. For
clarity, no review or consent of a party shall be required with respect to disclosures by either party of the Agreement and the transaction in such party’s reports filed with the SEC or to the extent such disclosure is consistent with
disclosure otherwise previously approved or publicly filed or disclosed pursuant to this Section 5.3. 

Section 5.4    Inspections and Audits of the
Sellers. Following the receipt of any Marketing Approval for the Product, upon at least fourteen (14) Business Days written notice and during normal business hours, no more frequently than once per calendar year, the Buyer may cause
an inspection and/or audit by an independent public accounting firm reasonably acceptable to the Sellers to be made of the Sellers’ books of account for the three (3) calendar years prior to the audit for the purpose of determining the
correctness of Royalties made under this Agreement. Upon the Buyer’s reasonable request not more than once in any calendar year while any Out-License remains in effect, the Sellers shall use commercially
reasonable efforts to exercise any rights it may have under any Out-License relating to a Product to cause an inspection and/or audit by an independent public accounting firm to be made of the books of account
of any counterparty thereto for the purpose of determining the correctness of Royalties made under this Agreement. All of the expenses of any inspection or audit requested by the Buyer hereunder 

  
 -8- 












 
(including the fees and expenses of such independent public accounting firm designated for such purpose) shall be borne by (i) the Buyer, if the independent public accounting firm determines
that Royalties previously paid were incorrect by an amount less than or equal to 5% of the Royalties actually paid or (ii) the Sellers, if the independent public accounting firm determines that Royalties previously paid were incorrect by an
amount greater than 5% of the Royalties actually paid. The terms on which any such independent public accounting firm is engaged shall provide that such independent public accounting firm may not disclose the confidential information of the Sellers
or any such counterparty to any Out-License relating to a Product to the Buyer, except to the extent such disclosure is either necessary to determine the correctness of Royalties or such confidential
information otherwise would be included in a Royalty Report. All information obtained by the Buyer as a result of any such inspection or audit shall be Confidential Information of Sellers subject to ARTICLE 7 and the independent public accounting
firm shall be considered a Representative of Buyer for purposes of ARTICLE 7. Absent manifest error, the audit of the independent public accounting firm will be final and non-appealable. Any payment owed by
one party to another as a result of the audit shall be made within ten (10) 
Business Days of receipt of the audit report. 
 Section 5.5   
 Intellectual Property Matters. 
 (a)    The Sellers shall provide to the Buyer a copy of any written
notice received by either of the Sellers from a Third Party alleging or claiming that the making, having made, using, importing, offering for sale or selling of a Product infringes or misappropriates any Patents or other intellectual property rights
of such Third Party, together with copies of material correspondence sent or received by the Sellers related thereto, as soon as practicable and in any event not more than ten (10) Business Days following such delivery or receipt. 

(b)    The Sellers shall promptly inform the Buyer in the event that any of the individuals named in the definition
of “Knowledge of the Seller” (or the successors of such Person at the Sellers) becomes aware of any actual infringement by a Third Party of any Patent Rights and shall provide to the Buyer copies of material correspondence
sent or received by either Seller related thereto, as soon as practicable and in any event not more than ten (10) Business Days following such delivery or receipt. 

(c)    If either Seller recovers monetary damages from a Third Party in an action brought for such Third
Party’s infringement of any Patent Rights in connection with the exploitation of any product, therapy or service that actually or prospectively competes with a Product or the market for such Product, where such damages (whether in the form of
judgment or settlement) are awarded for such infringement of such Patent Rights or loss of sales of such Product, (i) such damages will be allocated first to the reimbursement of any expenses incurred by the Sellers in bringing such action
(including reasonable attorney’s fees) not already reimbursed from other damages awarded under the same action, then (ii) any remaining amount of such damages will be reduced, if applicable, to comply with allocation of recovered damages
with licensors of such Patent Rights required under any In-Licenses or Permitted Licensees of such Patent Rights under any Out-Licenses, if any, and (iii) any
residual amount of such damages after application of (i) and (ii) will be treated as Net Sales of such Product for purposes of Royalties under this Agreement. 

Section 5.6    Efforts to Complete Clinical Trials and
Commercialize the Products. 
 (a)    The Sellers shall (directly or indirectly through an Affiliate or
Permitted Licensee) use commercially reasonable efforts to initiate, enroll patients in and complete Clinical Trials for the Product in the following indications: (a) wet age-related macular degeneration
(AMD), (b) diabetic macular edema (DME), and (c) retinal vein occlusion (including branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO)). The Sellers shall (directly or indirectly through an Affiliate or Permitted

Marketing Approval of the Product or of any Related Product in any Major Market, the Sellers (or its Affiliates or Permitted Licensees) shall use commercially reasonable efforts to Commercialize the Product or such Related Product in the
indication(s) for which such Product or Related Product has received Marketing Approval in each such Major Market where it has received such Marketing Approval.

material breach of its obligations under any Material In-License. The Sellers shall not terminate any Material In-License without providing the Buyer prior written

Intellectual Property Rights or Related Patent Rights including to develop, manufacture, promote, market, use, sell, offer for sale or import any Product or Related Product in all or any portion of the world without the Buyer’s consent (any

(e)    The Sellers shall provide the Buyer with written notice following the termination of any Out-License. 

Section 5.11    Negative Pledge; Preservation of Assets.

(b) Permitted Licenses to Permitted Licensees or (c) Permitted Liens. In connection with the incurrence of any Permitted Secured Indebtedness, at the request of the Sellers, the Buyer shall consider in good faith intercreditor arrangements
as necessary or appropriate to facilitate the incurrence of such Indebtedness; provided that any such arrangements shall be satisfactory to the Buyer. For the avoidance of doubt, nothing herein shall restrict the Sellers or any of their Subsidiaries
from incurring unsecured Indebtedness. 

Section 5.12    Use of Proceeds. Substantially all of
the amounts received by Sellers under this Agreement shall be used by Sellers and their Permitted Licensees solely for the research, development and Commercialization of the Products and Related Products. 

Section 5.13    True Sale. It is the intent of the
parties hereto that the sale, transfer, assignment and conveyance as contemplated by this Agreement shall constitute a sale of the Acquired Interests and neither Sellers nor Buyer intend the transactions contemplated by this Agreement to be, or for
any purpose characterized as, a loan from Buyer to Sellers or a pledge, a security interest, a financing transaction or a borrowing and accordingly, neither Sellers nor Buyer intend the transaction contemplated by this Agreement to be a partnership
or joint venture among Buyer and Sellers nor among Buyer, for any purpose. Sellers will treat the sale, transfer, assignment and conveyance of the Acquired Intangibles as sales of “accounts” and “payment intangibles” in
accordance with the UCC and Sellers each do hereby authorize Buyer, from and after the Closing, to file such financing statements (and continuation statements with respect to such financing statements when applicable) naming the Sellers as the
sellers and Buyer as the buyer of the Acquired Intangibles as may be necessary to perfect such sale. For the purpose of providing additional assurance to the Buyer in the event that, despite the intent of the parties hereto, the sale, transfer,
assignment and conveyance contemplated hereby is hereafter held not to be a sale, this Agreement shall constitute a security agreement and, effective upon the Closing, Sellers each hereby grants a security interest in, to, and under, the Acquired
Intangibles, and Sellers each hereby authorize Buyer to file such financing statements (and continuation statements with respect to such financing statements when applicable) as may be necessary to perfect such security interests. Each Seller and
Buyer hereby waives, to the maximum extent permitted by applicable law, any right to contest or otherwise assert that this Agreement does not constitute a true, complete, absolute and irrevocable sale, transfer, assignment and conveyance by Sellers
to Buyer of all of Sellers’ rights, title and interests in and to the Acquired Intangibles under applicable law, which waiver shall, to the maximum extent permitted by applicable law, be enforceable against each Seller in any bankruptcy or
insolvency proceeding relating to such Seller.

Claims. If either a Buyer Indemnified Party, on the one hand, or a Seller Indemnified Party, on the other hand (such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an
“Indemnified Party”), has suffered or incurred any Losses for which indemnification may be sought under this ARTICLE 6, the Indemnified Party shall so notify the other party from whom indemnification is sought under this
ARTICLE 6 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with
reasonable particularity and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred. If any claim, action, suit or proceeding is asserted or instituted by or against a Third Party with respect to
which an Indemnified Party intends to claim any Loss under this ARTICLE 6, such Indemnified Party shall promptly notify the Indemnifying Party of such claim, action, suit or proceeding and tender to the Indemnifying Party the defense of such claim,
action, suit or proceeding. A failure by an Indemnified Party to give notice and to tender the defense of such claim, action, suit or proceeding in a timely manner pursuant to this Section 6.2 shall not limit the obligation of the Indemnifying
Party under this ARTICLE 6, except to the extent such Indemnifying Party is actually prejudiced thereby. 

Section 6.3    Limitations on Liability. Except for
claims arising from a breach of confidentiality obligations under ARTICLE 7 or for claims for common law fraud, no party hereto shall be liable for any consequential, punitive, special or incidental damages under this ARTICLE 6 (and no claim for
indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such party (including under this ARTICLE 6) in or pursuant to this Agreement. 

Section 6.4    Exclusive Remedy. Except as set forth in

invoice price of the Product or Related Product, as applicable, that active contained in such Combination Product when sold separately in such country during the applicable accounting period in which the sales of the Combination Product were made,
and “B” is the combined weighted average invoice prices of all of the active ingredients other than price of the Product or Related Product contained in such Combination Product sold separately in such country during such same accounting
period. If the Product contained in such Combination Product is not sold separately in finished form in such country, the Sellers and the Buyer shall determine Net Sales for the Product by mutual agreement based on the relative contribution of the
Product and each such other active ingredient in such Combination Product in accordance with the above formula, and shall take into account in good faith any applicable allocations and calculations that may have been made for the same period in
other countries.

Section 9.5    Expenses. Except as otherwise provided
herein, all fees, costs and expenses (including any legal, accounting and banking fees) incurred in connection with the preparation, negotiation, execution and delivery of this Agreement and to consummate the transactions contemplated hereby shall
be paid by the party hereto incurring such fees, costs and expenses. 

Section 9.6    Assignment. Neither Seller may assign
this Agreement, any of its rights or obligations hereunder or any Product Rights, without the Buyer’s prior written consent, except to an Affiliate or Third Party (including without limitation a collaborator, licensee or joint venture partner)
in connection with the sale, license or transfer of all or substantially all of the Seller’s business or assets related to all Products (including this Agreement and the Product Rights), whether by merger, sale of assets, license,
reorganization or otherwise; provided that, in each case upon closing of any such transaction, the applicable Seller causes such Affiliate or Third Party, as applicable, to deliver a writing to the Buyer in which it assumes all of the obligations of
such Seller to the Buyer under this Agreement (including if applicable, Section 5.6(b)); provided that, for the avoidance of doubt, nothing in this Section 9.6 shall restrict the Sellers from licensing any Product Rights pursuant to a
Permitted License, from transferring the Marketing Approvals for any jurisdiction to a Licensee in connection with a Permitted License covering such jurisdiction or incurring any Liens permitted pursuant to Section 5.11. Buyer may assign all or
a portion of this Agreement or any rights to the Acquired Intangibles to any Person, including to any Third Party or to one or more of its Affiliates (each, an “Affiliate Assignee”), provided that (1) prior to the First
Commercial Sale, any such assignment, other than an assignment to an Affiliate Assignee, shall require the consent of the Sellers, not to be unreasonably withheld, conditioned or delayed, (2) no such assignment shall be permitted to a Person
that is primarily engaged in the development and Commercialization of pharmaceutical products or otherwise is not a financial investor, (3) such assignment shall not result in any material adverse Tax consequences to the Sellers that would not
have existed but for such assignment as determined by Sellers in good faith and evidenced by an opinion or written advice from nationally recognized tax counsel or a Big 4 accounting firm which shall be provided to Buyer upon request (provided,
however, that this clause (3) shall not prevent any assignment to an Affiliate Assignee (i) organized or formed in the United States, or (ii) tax resident in a jurisdiction with a comprehensive double tax treaty with the United States
in effect as of the date of the assignment that is eligible for the benefits of such double tax treaty), and, provided, further, that this clause (3) shall not prevent any assignment by Buyer (other than an assignment to an Affiliate Assignee
pursuant to the immediately preceding proviso) provided that Buyer or its assignee agrees to indemnify any incremental tax drag that arises for the Seller solely as a result of such assignment as evidenced by such opinion or written advice (and the
parties shall determine in good faith the creditworthiness of such indemnity, including, without limitation, the possibility of holding in escrow payments otherwise due to Buyer or its assignee, or escrowing a reasonable amount determined by the
parties in good faith), and (4) any such assignee agrees to assume all of the obligations of Buyer to the Sellers hereunder. This Agreement shall be binding upon, inure to the benefit of and be enforceable by, the parties hereto and their
respective permitted successors and assigns. Any purported assignment in violation of this Section 9.6 shall be null and void. The parties hereto acknowledge and agree that the Buyer intends to assign this Agreement to an Affiliate Assignee
prior to Closing. 
 Section 9.7    Amendment and
Waiver. 
 (a)    This Agreement may be amended, modified or supplemented only in a writing signed by each of
the parties hereto. Any provision of this Agreement may be waived only in a writing signed by the party hereto granting such waiver. 

(b)    No failure or delay on the part of any party hereto in exercising any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. No course of dealing between the parties
hereto shall be effective to amend, modify, supplement or waive any provision of this Agreement. 

Section 9.8    Entire Agreement. This Agreement, the
Exhibits annexed hereto and the Disclosure Schedule constitute the entire understanding between the parties hereto with respect to the subject matter hereof and supersede all other understandings and negotiations with respect thereto. 

Section 9.9    No Third Party Beneficiaries. This
Agreement is for the sole benefit of the Seller and the Buyer and their permitted successors and assigns and nothing herein expressed or implied shall give or be construed to give to any Person, other than the parties hereto and such successors and
assigns, any legal or equitable rights hereunder.

Section 9.10    Governing Law. This Agreement shall be
governed by, and construed in accordance with, the laws of the State of New York without giving effect to any choice or conflict of law provision or rule that would cause the application of the laws of any other jurisdiction. 

Section 9.11    Jurisdiction; Venue. 

(a)    EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS RESPECTIVE
PROPERTY AND ASSETS, TO THE EXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT OR FEDERAL COURT OF THE UNITED STATES OF AMERICA SITTING IN NEW YORK COUNTY, NEW YORK, AND ANY APPELLATE COURT THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF, AND THE BUYER AND THE SELLER HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREE THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. THE BUYER AND THE SELLER HEREBY AGREE THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE
ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY APPLICABLE LAW. EACH OF THE BUYER AND THE SELLER HEREBY SUBMITS TO THE EXCLUSIVE PERSONAL JURISDICTION AND VENUE OF SUCH NEW YORK STATE AND FEDERAL COURTS.
THE BUYER AND THE SELLER AGREE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THAT PROCESS MAY BE SERVED ON THE BUYER OR THE SELLER IN THE SAME MANNER THAT NOTICES MAY BE GIVEN PURSUANT TO SECTION 9.4 HEREOF. 

(b)    EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY
LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY NEW YORK STATE OR FEDERAL COURT. EACH OF THE BUYER AND THE SELLER
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT. 

Section 9.12    Severability. If any term or provision
of this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any situation in any jurisdiction, then, to the extent that the economic and legal substance of the transactions contemplated hereby is not affected in a
manner that is materially adverse to either party hereto, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect and the enforceability and validity of the offending term or provision shall not be
affected in any other situation or jurisdiction. 

Section 9.13    Specific Performance. Each of the
parties acknowledges and agrees that the other party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, each
of the parties agrees that, without posting bond or other undertaking, the other party will be entitled to seek an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to seek to enforce specifically
this Agreement and the terms and provisions hereof in any action, suit or other proceeding instituted in any court of the United States or any state thereof having jurisdiction over the parties and the matter in addition to any other remedy to which
it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it will not assert the defense that a remedy at law would be adequate. 

Section 9.14    Counterparts. This Agreement may be
executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Copies of
executed counterparts transmitted by telecopy, facsimile or other similar means of electronic transmission, including “PDF,” shall be considered original executed counterparts, provided receipt of such
counterparts is confirmed.

Section 9.15    Guarantee. Kodiak Inc. irrevocably and
unconditionally guarantees, as primary obligor and not merely as surety, the complete and timely performance of, and compliance with, all of the terms, covenants, conditions and provisions that are to be performed and complied with by the Kodiak
GmbH under this Agreement. Kodiak Inc. hereby acknowledges and agrees that Buyer may proceed directly against Kodiak Inc. in the event of non-performance by Kodiak GmbH. Kodiak Inc. is jointly and severally
liable with Kodiak GmbH for the performance of, and compliance with, the terms, covenants, conditions and provisions to be performed and complied with by the Purchaser under this Agreement. Kodiak Inc. will pay and perform its liabilities and
obligations under this Section 9.15 as soon as reasonably possible after valid demand for any payment or performance is made in writing to it. Kodiak Inc. hereby unconditionally and irrevocably waives for the benefit of the Buyer any defenses
to enforcement it may have (now or in the future) by reason of any circumstance whatsoever which might, but for the provisions of this clause, constitute a legal or equitable discharge of its obligations under this Section 9.15 (except that
Kodiak Inc. may assert the defense of payment in full of the obligations guaranteed by it hereunder). 

Section 9.16    Relationship of the Parties. The
relationship between the Buyer and the Sellers is solely that of purchaser and seller, and neither the Buyer nor any of the Sellers has any fiduciary or other special relationship with the other party or any of its Affiliates. This Agreement is not
a partnership or similar agreement, and nothing contained herein shall be deemed to constitute the Buyer and the Sellers as a partnership, an association, a joint venture or any other kind of entity or legal form for any purposes, including any Tax
purposes. The Buyer and the Sellers agree that they shall not take any inconsistent position with respect to such treatment in a filing with any Governmental Entity. 

Section 9.17    Withholding. 

(a)    Notwithstanding anything herein to the contrary, payments made or to be made to the Buyer or its assignees
hereunder will be made free and clear of and without deduction for any and all Taxes, provided that the Sellers shall be entitled to deduct and withhold from the payments otherwise required pursuant to this Agreement any such Taxes as the Sellers
may be required to deduct and withhold with respect to any such payments under applicable law (it being understood that, solely with respect to U.S. federal withholding Tax, Sellers shall not make any such deduction or withholding if Sellers have
received, as applicable, either (i) a valid, properly executed Internal Revenue Service Form W-9 certifying that the Buyer or the relevant assignee, as applicable, is exempt from U.S. “backup”
withholding Tax or (ii) a valid, properly executed Internal Revenue Service Form W-8BEN-E (or other applicable W-8, with any
necessary accompanying attachments) certifying that the Buyer or the relevant assignee, as applicable, is exempt from U.S. federal withholding Tax under a United States income Tax treaty with respect to royalties and other income). If the Sellers
are required by applicable law to deduct and withhold any Taxes from any such payment, then the sum payable by the Sellers shall be increased as necessary so that after deduction or withholding has been made for any such Tax (other than any Tax that
is imposed on or measured by net income), the applicable recipient receive an amount equal to the sum it would have received had no such deduction or withholding been made (including such deduction or withholding applicable to such additional amount
payable), and the Sellers shall indemnify and hold harmless the applicable recipient against any such Taxes (or any Taxes imposed or asserted on, or attributable to, amounts payable hereunder, other than any such Tax that is imposed on or measured
by net income) and any reasonable expenses arising therefrom or with respect thereto. Notwithstanding the foregoing, the increase of the sum payable and the indemnification obligation described in the immediately preceding sentence shall not be
required: (i) with respect to any non-Swiss withholding Tax (except to the extent such non-Swiss withholding Tax (A) is imposed as a result of an assignment by
a Seller pursuant to Section 9.6, and would not have been imposed but for such assignment and (B) could not be avoided by the Buyer’s or an assignee of Buyer’s provision of applicable tax forms to Seller to the extent reasonably
necessary under applicable law) or (ii) with respect to payments to any permitted assignee of Buyer pursuant to Section 9.6, to the extent relating to Taxes imposed on such permitted assignee pursuant to a law in effect on the date such
permitted assignee acquired its interest in this Agreement, to the extent such Taxes exceed the Taxes that would have been imposed on Buyer pursuant to applicable law in effect on the date of such assignment (and, for the avoidance of doubt, the
increase of the sum payable and the indemnification obligation shall remain required to the extent such Taxes imposed on such permitted assignee do not exceed the Taxes that would have been imposed on Buyer). Notwithstanding anything in this
Section 9.17(a), an increase of the sum payable and the indemnification obligation shall also be required in case of any assignment by a Seller pursuant to Section 9.6 that gives rise to any tax that is imposed on a gross basis in lieu of
a withholding tax that would not have been imposed but for such assignment.

 (b)    The Buyer hereby agrees to cooperate in good faith with
the Sellers to mitigate the amount of any of such Taxes which Sellers bear pursuant to this Section 9.17, provided, however, that the Buyer shall determine in its sole discretion whether, or the extent to which, its investors shall be involved
or be required to be involved in connection with the foregoing. 
 (c)    Notwithstanding anything herein to the
contrary, (i) the parties hereunder shall make all payments required to be made pursuant to this Agreement in U.S. dollars by wire transfer of immediately available funds to the bank account designated in writing from time to time by the other
party, and (ii) any such payments made by the Buyer shall be made (A) solely with respect to any non-Swiss Taxes that are not U.S. federal withholding taxes and except in case of any assignment by a
Seller pursuant to Section 9.6, without set-off, reduction or deduction, or withholding for or on account of such non-Swiss Taxes and (B) so long as the
Sellers have provided to the Buyer a valid, properly executed Internal Revenue Service Form W-9 and W-8BEN-E or other applicable
form described in Section 4.1(b), without set-off, reduction or deduction, or withholding for or on account of any U.S. federal withholding taxes. 

Section 9.18    Tax Treatment. The Buyer and
Sellers agree that, for U.S. federal and Swiss income tax purposes, (a) payments received by the Sellers under this Agreement are for the acquisition or license of an interest in Intellectual Property Rights and/or funding the research services
that will benefit both the Buyer and the Sellers, and (b) payments received by the Buyer under this Agreement are for the use of Intellectual Property Rights acquired and developed under this Agreement. To that end, the Buyer and Sellers
acknowledge that Sellers may allocate all or a portion of the payments received under this Agreement to prepaid royalties and/or prepaid services (but not to any securities of the Sellers or rights to subscribe therein that Buyer may obtain), and
the Buyer will allocate its payments received to the Intellectual Property Rights. The Buyer and Sellers agree that, if either determines in good faith that any provision hereunder is inconsistent with such treatment, the Buyer and Sellers shall
substitute, by mutual consent, provisions consistent with such intended tax treatment for such inconsistent provision, and such provisions shall be effective as of the Effective Date.
