4.Fees, Royalties and Payment.

a.Importance of Technical Information and Materials. Company has requested, and Columbia and VHIR have agreed, to grant certain rights to Technical Information and Materials. Company requires these rights in order to develop and commercialize the technology licensed hereunder. Because of the importance of Technical Information and Materials, Company has agreed to pay certain royalties to Columbia on Other Products, as specified below, even if it is not Covered By a Patent, in order to obtain rights to Technical Information and Materials. Company has agreed to these payments because of the commercial value of Technical Information and Materials, separate and distinct from the commercial value of the Patents. Company acknowledges that it would not have entered into this Agreement without receiving the rights to the Technical Information and Materials specified in Section 2. Company further acknowledges that licenses to Technical Information, Materials, and each patent and application within the definition of Patents were separately available from a license to the Patents, and that for convenience and because of the preference of Company, the parties executed a combined license to the Patents, Technical Information, and Materials.

b.In consideration of the licenses granted under Section 2a of this Agreement, the Company shall pay to Columbia as follows:

(i)License Fee: A one-time nonrefundable, non-recoverable and non-creditable license fee in the sum of $[***], payable within 15 days of execution of this Agreement;

(ii)Annual Fee: Company shall pay Columbia an annual license maintenance fee within thirty days following the applicable anniversary of the Effective Date (the “Annual Fee”), as follows:

(A)$[***] for the first, second and third anniversary;

(B)$[***] for each subsequent anniversary until the submission of an NDA.

Upon the submission of an NDA the obligation to pay the Annual Fee shall terminate.

Any Milestone Payments paid pursuant to Section 4e below in the 12-month period preceding an Effective Date for which an Annual Fee is due shall be credited towards the respective Annual Fee.

Accrued Annual Fees shall be fully creditable against Milestone Payments due pursuant to Section 4e below.

(iii)Royalties:

(A)Except as otherwise set forth in this Agreement, with respect to sales of Patent Products by Company, its Sublicensees or their Affiliates, in the Territory, a nonrefundable and non-recoverable royalty of:

(1)[***] ([***]%) of the first [***] ($[***]) of aggregate Net Sales of Patent Products sold by Company, its Affiliates, or Sublicensees in the Territory in any Calendar Year;

(2)[***] ([***]%) of all Net Sales of Patent Products sold by Company, its Affiliates, or Sublicensees in the Territory greater than [***] ($[***]) and up to [***] ($[***]) in any Calendar Year; and

(3)[***] ([***]%) of all Net Sales of Patent Products sold by Company, its Affiliates, or Sublicensees in the Territory greater than [***] ($[***]) in any Calendar Year (the applicable percentage, pursuant to the foregoing, of Net Sales of Products sold by Company, its Affiliates, or Sublicensees in the Territory, the “Base Rate”).

(B)With respect to sales of Other Products by Company, its Sublicensees or their Affiliates or Sublicensees, in the Territory, a nonrefundable and non-recoverable royalty of:

(1)[***]% of the royalty rates set forth in Section 4b(iii)(A) on the Net Sales of Other Products sold in a country in the Territory for which there was orphan drug exclusivity at the time of such sale;

(2)[***]% of the royalty rates set forth in Section 4b(iii)(A) on the Net Sales of Other Products sold in a country in the Territory for which there was no orphan drug exclusivity at the time of such sale; and

(3)[***]% of the royalty rates set forth in Section 4b(iii)(A) on the Net Sales of Other Products if there is, at the time of sale, a Generic Equivalent for sale in the country of sale.

(C)In the event that the royalties paid to Columbia pursuant to Section 4b(iii) in any full Calendar Year following the Calendar Year in which the First Commercial Sale of a Product occurs do not exceed [***] ($[***]), Company shall pay to Columbia the difference between such minimum royalty amount and the actual royalties paid within [***] days following the last day of such Calendar Year.

(D)If Company, an Affiliate thereof, or any Sublicensee reasonably determines that it is necessary or advisable to obtain a license to any patent(s) or patent application(s) owned, licensed, or controlled by a Third Party in order to minimize, mitigate, or avoid the risk of infringement-related litigation with respect to the manufacture, use, delivery, or sale of a Product, then Company shall provide written notice of such determination to Columbia. If Company, an Affiliate thereof, or any Sublicensee pays fees, milestones, royalties, or other consideration to any such Third Party for any such rights (such consideration, “Third Party Royalties”), then Company may deduct [***] ([***]%) of the Third Party Royalties from any payments due Columbia under Section 4b(iii); provided that in no event will the royalties due to Columbia under Section 4b(iii) of this Agreement be reduced by more than [***]% by the offset in this Section 4b(iii)(D).

c. Company will pay Columbia an amount equal to the following percentages of all Sublicensing Revenue:

(i)if the respective sublicense was granted prior to the filing of an IND for a Product, [***]% of Sublicensing Revenue;

(ii)if the respective sublicense was granted following the filing of an IND for a Product and prior to the receipt by the Company or its Affiliates of the results (i.e., whether or not the clinical trial achieved its clinical endpoint) of a clinical trial covering a Product, then:

(A)[***]% of Sublicensing Revenue, if the agreement under which such sublicense is granted is not a PRV Sublicense; and

(B)[***]% of Sublicensing Revenue, if the agreement under which such sublicense is granted is a PRV Sublicense;

(iii)if the respective sublicense was granted (a) following the receipt by the Company or its Affiliates of the results (i.e., whether or not the clinical trial achieved its clinical endpoint) of a clinical trial covering a Product but (b) prior to the filing of an NDA for a Product,

(A)[***]% of Sublicensing Revenue, if the agreement under which such sublicense is granted is not a PRV Sublicense; and

(B)[***]% of Sublicensing Revenue, if the agreement under which such sublicense is granted is a PRV Sublicense;

(iv)if the respective sublicense is a PRV Sublicense and is effective following the filing of an NDA for a Product, [***]% of Sublicensing Revenue. For the avoidance of doubt, if a sublicense is granted following the filing of an NDA for a Product and the respective agreement is not a PRV Sublicense, then no share of Sublicensing Revenue is payable to Columbia.

Milestone Payments paid by Company shall be credited against the payments due under this Section 4c.

Until such time as Company has received Sublicensing Revenue of at least [***] ($[***]), the Sublicensing Revenue on which payments due under this Section 4c are based shall be reduced by an amount equal to Company’s direct and indirect research and development costs and expenses (as

determined from the books and records of Company and its Affiliates maintained in accordance with such reasonable accounting principles as may be consistently applied by Company or its Affiliates) for Products (the “Deferred Sublicensing Revenue”), up to a maximum reduction of [***] ($[***]), and Company shall not be responsible for paying a royalty on the Deferred Sublicensing Revenue. Upon Company’s receipt of Sublicensing Revenue of at least [***] ($[***]), Company shall pay Columbia a one-time payment equal to the applicable percentage (as set forth above) multiplied by the Deferred Sublicensing Revenue.

d. Priority Review Voucher Revenue Share. Company will pay Columbia an amount equal to [***]% of Priority Review Voucher Revenue.

e. Development Milestone Payments: The following one-time nonrefundable, non-recoverable and non-creditable (other than against the Annual Fee as described in Section 4b(ii) and Sublicensing Revenue as described in Section 4(c) milestone payments (“Milestone Payments”) shall be made by Company to Columbia within sixty (60) calendar days of the initial achievement of the indicated milestone. Accrued Annual Fees shall be fully creditable against Milestone Payments due.

f. Duration of Other Product Royalties. Royalties shall be payable on a country-by-country and product-by-product basis until the later of (i) [***] after the first bona fide commercial sale of a Product in a country, (ii) the expiration of the last to expire Valid Claim covering a Product in a country or (iii) expiration of any Regulatory Exclusivity covering such Product (the “Royalty Term”).

g. Highest Royalty Due. If a Product is covered by both the definition of Patent Product and Other Product, Columbia shall be entitled to the Patent Product royalty rate on the Product. Columbia shall not be entitled to more than one royalty payment on the same Product sale under Section 4. To the extent a Product ceases being a Patent Product, but is still an Other Product, Columbia shall be entitled to the Other Product royalty rate on the Product, but only for such time as specified in Section 4(f).

h. No Non-Monetary Consideration. Without Columbia’s prior written consent, such consent not to be unreasonably withheld, Company, Sublicensees, and Affiliates of the foregoing, shall not solicit or accept any consideration for the sale of any Product other than as will be accurately reflected in Net Sales. Furthermore, Company shall not enter into any transaction with any Affiliate that would circumvent its monetary or other obligations under this Agreement.

i. Rate Adjustment on Challenge; Payment of Costs and Expenses.

(i)In the event Company (or any entity or person acting on its behalf) initiates any Challenge, all royalty rates, minimum royalties, and other payment rates set forth in Sections 4b(iii) and 4c shall be automatically [***] on and after the date of such challenge for the remaining term of this Agreement.

(ii)Company shall pay all reasonable, documented, out-of-pocket costs and expenses incurred by Columbia (including actual attorneys’ fees) in connection with defending a Challenge. Columbia may bill Company on a quarterly basis with respect to such costs and expenses, and Company shall make payment within thirty (30) days after receiving an invoice from Columbia.

(iii)In the event at least one claim of a Patent that is subject to a Challenge survives the Challenge by not being found invalid or unenforceable, regardless of whether the claim is amended as part of the Challenge, all royalty rates, minimum royalties, and other payment rates set forth in Sections 4b(iii) and 4c shall be automatically trebled on and after the date of such finding for the remaining term of this Agreement.

Company acknowledges and agrees that the provisions set forth in this Section 4(i) reasonably reflect the value derived from the Agreement by Company in the event of a Challenge. In addition, Company acknowledges and agrees that any payments made under this Section 4(i) shall be nonrefundable and non-recoverable for any reason whatsoever.

j. Sale Below Fair Market Value. In the event that Company, Sublicensees, or their Affiliates sell Product to a Third Party in a transaction that is not at arms-length, the price for Licensed Product shall not be established such that Net Sales is below fair market value with the intent of increasing market share for other products sold by Company, Sublicensees, or their Affiliates to such Third Party or for the purpose of reducing the amount of royalties payable on the Net Sales of Product. If the sale of Product under such circumstances results in Net Sales below the fair market value of Product sold in an arms-length transaction, then the Net Sales of Product in such transaction shall be deemed to be the fair market value of Product sold in an arm’s length transaction for purposes of calculating payments owed to Columbia under this Agreement.

k. Subject to Columbia and Company executing a mutually agreed upon subscription agreement within three months of the Effective Date, Company shall issue to Columbia membership units (“Membership Units”) representing [***] ([***]%) of the Company’s outstanding membership units as of the Effective Date.

The Anti-Dilution Protection shall terminate on the earlier of the following: (i) IPO, (ii) a Change of Control of Company, or (iii) the Company’s receipt of a total of [***] ($[***]) in equity financing (including, for purposes of such calculation, the amount of any unpaid principal and interest due under any debt securities that may be converted into or used to purchase equity securities in any equity financing; provided, however, that such amount of unpaid principal and interest shall not be applied to the $[***] threshold until and to the extent such debt is converted into or used to purchase equity securities). For the avoidance of doubt, the Anti-Dilution Protection shall not apply to equity financing in excess of [***] ($[***]).

l. Upon the mutual execution of such subscription agreement and issuance of Membership Units as described above, Company grants to Columbia the right to designate non-voting Board Observer(s) who may attend, observe or otherwise participate in all meetings of the Board of Directors of the Company. The foregoing right shall terminate upon the earlier of (i) an IPO, (ii) Change of Control of the Company or (iii) Columbia no longer holding more than [***]% of Membership Interests on fully diluted basis.

c.Within sixty (60) days after the date of termination or expiration of this Agreement, Company shall pay Columbia any and all amounts that are due pursuant to this Agreement as of the date of such termination or expiration, together with a Payment Report for such payment in accordance with Section 5a hereof, except that such Payment Report shall cover the period from the end of the last Calendar Year prior to termination or expiration to the date of termination or expiration. Nothing in the foregoing shall be deemed to satisfy any of Company’s other obligations under this Agreement upon termination or expiration.

d.Minimum royalty payments are payable in accordance with Section 4b(iii)(C).

e.With respect to revenues obtained by Company in foreign countries, Company shall make royalty payments to Columbia in the United States in United States Dollars. Royalty payments for transactions outside the United States shall first be determined in the currency of the country in which they are earned, and then converted to United States dollars using the buying rates of exchange quoted by The Wall Street Journal (or its successor) in New York, New York for the last business day of the calendar quarter in which the royalties were earned. Any and all loss of exchange value, taxes, or other expenses incurred in the transfer or conversion of foreign currency into U.S. dollars, and any income, remittance, or other taxes on such royalties required to be withheld at the source shall be the exclusive responsibility of Company, and shall not be used to decrease the amount of royalties due to Columbia. Notwithstanding the foregoing, all payments made by Company in fulfillment of Columbia’s tax liability in any particular country may be credited against earned royalties or fees due Columbia for that country. Royalty statements shall show sales both in the local currency and US dollars, with the exchange rate used clearly stated.

f.Company shall maintain at its principal office usual books of account and records showing its actions under this Agreement, and sufficient to determine Company’s compliance with its obligations hereunder. Upon reasonable notice, but not more than once per Calendar Year, Columbia may have a certified public accountant or auditor, (each as to whom Company has pre-approved in writing, such approval to not be unreasonably withheld) inspect such books and records for purposes of verifying the accuracy of the amounts paid under this Agreement. Prior to any such inspection, such accountant or auditor shall enter into a reasonably confidential disclosure agreement with Company. Such certified public accountant and accountant shall not disclose to Columbia any information other than information reasonably relating to the accuracy of payments made under this Agreement, and all such information shall be deemed Confidential Information of Company except as necessary to legally enforce the provisions of this Section 5f. The review may cover a period of not more than five (5) years before the first day of the Calendar Year in which the review is requested. In the event that such review shows that Company has underpaid royalties by five percent (5%) or more with respect to any calendar quarter, or if such underpayment is in excess of $50,000 for any calendar quarter, or an aggregate of $100,000 for any Calendar Year, and Company does not dispute such review, Company shall pay, within ten days after demand by Columbia, the reasonable, documented out-of-pocket costs and expenses of such review (including the fees charged by Columbia’s accountant or auditor involved in the review), in addition to amount of any underpayment and any interest thereon. Company agrees to reasonably cooperate with such certified public accountant or auditor in connection with the inspection described above. During the review, Company shall provide Columbia’s accountant or auditor with all information reasonably requested to allow the accountant or auditor to audit and test for completeness of Company’s reports as well as accuracy of reported fees payable to Columbia, including, without limitation, information relating to sales, inventory, country of manufacture, transfer records, invoices, purchase orders, sales orders, shipping documentation, Third Party royalty reports, costs associated with royalties, pricing policies, and agreements with Third Parties (including Sublicensees, Affiliates of Company, Sublicensees and customers), but only to the extent reasonably necessary to determine completeness of Company’s reports as well as the accuracy of the payments due hereunder. All information disclosed by Company to Columbia’s accountant or auditor will be treated as confidential.

g.Notwithstanding anything to the contrary in this Agreement, and without limiting any of Columbia’s rights and remedies hereunder, any payment required hereunder that is made late (including unpaid portions of amounts due) shall bear interest, compounded monthly, at the rate of [***]% per annum. Any interest charged or paid in excess of the maximum rate permitted by applicable New York State Law shall be deemed the result of a mistake and interest paid in excess of the maximum rate shall be credited or refunded (at the Company’s option) to Company.

6. Diligence.

a.Company shall use its Commercially Reasonable Efforts to research, discover, develop and market Products for commercial sale and distribution in the Territory. Columbia agrees that the efforts of Sublicensees, Affiliates, Designees, and Third Party contractors shall be deemed the acts of Company for purposes of satisfying this Section 6a.

b.Company shall use Commercially Reasonable Efforts to: (i) submit an IND to the FDA within [***] of the Effective Date, (ii) initiate a phase II clinical trial or phase III clinical trial involving a Product within [***] of the Effective Date and (iii) achieve the first commercial sale of a Product within [***] of the Effective Date. Prior to the achievement of the foregoing milestones, Company will be deemed to not be using Commercially Reasonable Efforts to achieve such milestones if in any twelve consecutive month period prior to the dosing of the first patient in a Pivotal Clinical Trial, Company does not engage in any activity relating to the research, development or manufacturing of Products. In the event that there are changes in technical and regulatory factors, target product profiles, product labeling, costs, market conditions, and regulatory environment that the Company believes would affect the timely achievement of any milestone, Company may request an extension from Columbia for such milestone, which will not be unreasonably withheld. Columbia agrees that the efforts of Sublicensees, Affiliates, Designees, and Third Party contractors shall be deemed the acts of Company for purposes of satisfying this Section 6b.

c.Notwithstanding any other provisions of this Agreement, upon a material breach of Section 6b by Company, followed by written notice by Columbia of such breach and a ninety (90) or 180 day period to cure as applicable under Section 16 (with Company not curing such breach during such period), Columbia shall have the option of [***].

d.On or before February 1 of each year after the Effective Date of this Agreement, Company shall report in writing to Columbia on progress made toward the diligence objectives set forth in Section 6b. All reports provided to Columbia pursuant to this Section shall be deemed Company’s Confidential Information.

Columbia shall instruct its patent counsel (1) to copy Company on all correspondence related to Patents (including copies of each patent application, office action, response to office action, request for terminal disclaimer, and request for reissue or reexamination of any patent or patent application), as well as copies of all proposed responses to such correspondence in time for Company to review and comment on such response, (2) consult with Company, and reasonably consider Company’s comments and suggestions regarding matters relating to securing and maintaining the Patents, and (3) as requested by Company, to provide an update as to the current status of all Patents.

Each party shall treat such consultation, along with any information disclosed by each party in connection therewith (including any information concerning patent expenses), on a strictly confidential basis, and shall not disclose such consultation or information to any party without the other party’s prior written consent. If Company seeks to challenge the validity, enforceability or scope of any Patent, Columbia’s consultation obligation under this Section 11a shall automatically terminate; for the avoidance of doubt, any such termination shall not affect Company’s confidentiality and nondisclosure obligations with respect to consultation or disclosure of information prior to such termination, and shall not affect any other provisions of this Agreement (including Company’s reimbursement obligation under Section 11b).

b.Company will reimburse Columbia for the reasonable, documented actual fees, costs, and expenses Columbia has incurred prior to June 30, 2016 and will pay the reasonable, documented actual fees, costs, and expenses that Columbia incurs following June 30, 2016 in preparing, filing, prosecuting and maintaining the Patents and those past reasonable, documented patent expenses Columbia incurred prior to June 30, 2016 relating to the following patents and patent applications to which Patents claim priority: United State Provisional Application Nos. 62/138,583 and 62/180,914, including without limitation, attorneys’ fees, the costs of any interference proceedings, oppositions, reexaminations, or any other ex parte or inter partes administrative proceeding before patent offices, taxes, annuities, issue fees, working fees, maintenance fees and renewal charges (collectively “Patent Expenses”).

Patent Expenses incurred by Columbia after June 30, 2016 shall be reimbursed to Columbia by Company within thirty (30) days of receiving Columbia’s invoice. If Company decides that it does not wish to pay for the preparation, filing, prosecution, protection or maintenance of any Patents in a particular country (“Abandoned Patent Rights”), Company shall provide Columbia with prompt written notice of such election. Upon receipt of such notice by Columbia, Company shall be released from its obligation to reimburse Columbia for the expenses incurred thereafter as to such Abandoned Patent Rights. Any license granted by Columbia to Company hereunder with respect to Abandoned Patent Rights will terminate.

c.Each party shall promptly notify the other in writing of any actual, alleged or threatened challenge to the validity or enforceability of, Patents of which it becomes aware. Columbia shall have the first right to defend, control and settle any such validity or enforceability challenges.

d.In the event either party becomes aware of any possible or actual infringement of any Patents, that party shall promptly notify the other party and provide it with details regarding such infringement. Company will have the first right, at its expense, to initiate a suit or take other appropriate action that it believes is reasonably required to protect (i.e., prevent or abate actual or threatened infringement or misappropriation of) or otherwise enforce the Patents, including defending against any counterclaims or cross claims brought by any party against Company or Columbia regarding the Patents, subject to the provisions of Section 11c above. Before commencing any such suit, Company shall consult with Columbia concerning the advisability of bringing suit, the selection of counsel and the jurisdiction for such action and shall use reasonable efforts to accommodate the views of Columbia regarding the proposed action. If required under applicable law in order for Company to initiate or maintain such suit, or to collect damages, Columbia shall join as a party to the suit at Company’s expense. Upon Company’s request and at Company’s expense, Columbia shall provide reasonable assistance to Company in connection with an action brought under this Section. Any proposed disposition or settlement of a legal proceeding filed by Company pursuant to this Section 11d to enforce any issued patent falling within the definition of Patents against any third party infringer shall be subject to Columbia’s prior written approval, which approval shall not be unreasonably withheld or delayed. If Company fails to initiate a suit or take other appropriate action within ninety (90) days after becoming aware of the basis for such suit or action, then Columbia may, in its discretion, provide Company with written notice of Columbia’s intent to initiate a suit or take other appropriate action with respect to such infringement or misappropriation of the Patents; provided that prior to initiating any such suit, Columbia shall consult with Company concerning the advisability of bringing suit, the selection of counsel and the jurisdiction for such action, and shall use reasonable efforts to accommodate the views of Company regarding the proposed action. If Columbia brings such suit, upon Columbia’s request, Company shall provide reasonable assistance to Columbia in connection therewith and Columbia shall be responsible to Company for all reasonable out-of-pocket costs and expenses. Notwithstanding the foregoing, Company’s rights under this Section 11d shall apply only to claims of Patents that are exclusively licensed to Company under this Agreement and only in the Field and Territory that are exclusively licensed to Company under this Agreement.

e.Any recovery, whether by way of settlement or judgment, from a third party pursuant to a legal proceeding initiated in accordance with Section 11d shall first be used to reimburse the Parties for their reasonable, documented fees, costs and expenses incurred in connection with such proceeding. Any remaining amounts from any such settlement or judgment shall be divided as follows: (A) the portion thereof attributable to “lost sales” shall be retained by the Company and deemed to be Net Sales for the Calendar Year in which the amount is actually received by Company, and Company shall pay to Columbia a royalty on such Net Sales as set forth in Section 4b(iii) and (B) the portion thereof not attributable to “lost sales” shall be divided [***]% to the party who initiated or carried on the proceedings and [***]% to the other party.

f.In the event a party initiates or defends a legal proceeding concerning any Patent pursuant to Section 11, the other party shall cooperate fully with and supply all assistance reasonably requested by the party initiating such proceeding, including without limitation, joining the proceeding as a party if requested and the initiating party shall be responsible for all reasonable out-of-pocket expense incurred by the non-initiating party. The party that institutes any legal proceeding concerning any Patent pursuant to Section 11 shall have sole control of that proceeding.

g.Upon Company’s request and at Company’s expense, Columbia shall apply for a patent term extension, adjustment or restoration, supplementary protection certificate, or other form of market exclusivity conferred by applicable laws, rules, regulations, or guidelines in the relevant country.

12. Indemnity and Insurance.

a.Company will indemnify, defend, and hold harmless Columbia, VHIR, its trustees, officers, faculty, employees, students and agents (collectively, “Indemnitees”), from and against any and all actions, suits, claims, demands, prosecutions, liabilities, costs, expenses, damages, deficiencies, losses or obligations (including attorneys’ fees) due to any claim by a Third Party (“Claim”) based on or arising out of, the exercise by Company, its Affiliates or Sublicensee of the rights and licenses granted to Company under this Agreement, including, without limitation, (i) the discovery, development, manufacture, packaging, use, sale, offering for sale, importation, exportation, distribution, rental or lease of Products, (ii) the use of Patents, Materials or Technical Information by Company, Sublicensees, Designees, or their Affiliates or customers, (iii) any representation made or warranty given by Company, Sublicensees, Designees, or their Affiliates with respect to Products, Patents, Materials or Technical Information, (iv) any infringement claims relating to Products, Patents, Materials or Technical Information, and (v) any asserted violation of the Export Laws (as defined in Section 14 hereof) by Company, Sublicensees, Designees, or their Affiliates. The previous sentence will not apply to the extent that any Claim is based on our arises out of (i) the gross negligence or willful misconduct of an Indemnitee or (ii) from any breach of Section 8a.

Company’s indemnification obligations under the preceding paragraph are conditioned upon (i) Columbia and VHIR notifying Company of any Claim hereunder as soon as reasonably practicable after it receives notice of the Claim; provided that the failure so to notify Company will relieve Company from liability for indemnification only if and to the extent such failure results in additional costs, expenses or liability, (ii) Columbia, VHIR and the Indemnitees permitting Company to assume direction and control of the defense of the Claim (including the right to settle the Claim); provided, however, that Company shall not settle any Claim without the prior written consent of Columbia or VHIR, such consent not to be unreasonably withheld, where such settlement (a) would include any admission of liability on the part of any Indemnitee or (b) would impose any restriction on any Indemnitee’s conduct of any of its activities or (c) would affect the validity or enforceability of any Patent and (iii) the Indemnitees shall cooperate as reasonably requested (at the expense of Company) in the investigation and defense of any Claim, and may not settle a Claim without the express written consent of Company.

b.Beginning at least ten (10) business days before the time any Product is being marketed or commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by Company, or by an Affiliate or Sublicensee, Company shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $5,000,000 per incident and $5,000,000 annual aggregate. During clinical trials of any such Product, Company shall, at its sole cost and expense, procure and maintain commercial general liability insurance in such equal or lesser amount as is customary. Such insurance shall include Columbia, VHIR, its trustees, faculty, officers, employees and agents as additional insureds. Company shall furnish a certificate of insurance evidencing such coverage, with thirty days’ written notice to Columbia following cancellation or material change in coverage. The minimum amounts of insurance coverage required herein shall not be construed as creating any limitation on the Company’s indemnity obligation under Section 12a of this Agreement.

b.Unless terminated earlier under any provision of this Agreement, the term of this Agreement shall commence on the Effective Date and, unless earlier terminated as provided in this Section 16 shall continue in full force and effect, on a country-by-country and Product-by-Product basis until the Royalty Term in such country with respect to such Product expires, at which time this Agreement shall expire in its entirety with respect to such Product in such country. Upon expiration of the Royalty Term for a particular country and Product, Company, its Affiliates, and Sublicensees shall, notwithstanding anything herein to the contrary, have and are hereby granted a perpetual, irrevocable, fully-paid, royalty-free, transferable, sublicenseable right and license under the Technical Information and Materials to make, use, sell, offer for sale, and import such Product in such country.

c.If either party materially breaches this Agreement at any time, the non-breaching Party shall have the right to terminate this Agreement by written notice to the breaching Party, if (a) such material breach is not cured within ninety (90) calendar days following notice by the non-breaching party to the breaching party specifying the material breach (or, if such default is capable of being cured but cannot be cured within such 90-day period, the breaching party has commenced and diligently continued actions to cure such default provided always that, in such instance, such cure must have occurred within one hundred eighty (180) calendar days after notice thereof was provided to the breaching party by the non-breaching party to remedy such default) and (b) the non-breaching party provides notice confirming such termination within thirty (30) calendar days following the expiration of such ninety (90) or one hundred eighty (180) calendar day period, as applicable, without cure of such material breach. The foregoing notwithstanding, if such material breach is cured or remedied or shown to be non-existent within the aforesaid ninety (90) or one hundred eighty (180) calendar day period, the non-breaching party’s notice(s) hereunder shall be automatically withdrawn and of no effect.

e.Company, in its sole discretion, shall have the right to terminate, for its convenience, this Agreement in its entirety or on a Product-by-Product and country-by-country basis, upon sixty (60) days prior written notice, provided that Company is not making, using, selling, importing or exporting Products in such country(ies).

f.Notwithstanding anything to the contrary herein, upon termination of this Agreement prior to its expiration, any sublicenses granted by Company or any Affiliate thereof under the Patents, Technical Information and Materials shall, to the extent provided in the sublicense agreement, remain in effect and be assigned to and assumed by, Columbia, provided that: (i) if rights to intellectual property or property other than the Patents, Technical Information and Materials are licensed to the Sublicensee under such sublicense, such assignment and assumption shall be partial and limited to the Patents, Technical Information and Materials, (ii) Columbia shall not assume any obligations under such sublicense in excess of its obligations hereunder, and (iii) the Sublicensee shall thereafter pay Columbia any consideration that would have been due to Columbia hereunder with respect to the rights granted to such Sublicensee under the Patents, Technical Information and Materials in such sublicense (in lieu of the payment obligations set forth in such sublicense).

Any notice required or permitted to be given under this Agreement shall be sufficient if in writing and shall be considered given (i) when mailed by certified mail (return receipt requested), postage prepaid, or (ii) on the date of actual delivery by hand or overnight delivery, with receipt acknowledged,

18. Assignment.

Neither party may assign this Agreement, or any of its rights or obligations hereunder without the other party’s prior written consent, which consent shall not be unreasonably withheld, provided that, notwithstanding the foregoing, each party shall be entitled, without the other Party’s prior written consent, to assign or transfer this Agreement: (a) in connection with the transfer or sale of all or substantially all of such party’s assets or business or (b) in the event of such party’s merger, consolidation, reorganization, Change of Control or similar transaction. Any permitted assignee of either party shall, as a condition to such assignment, assume all obligations of its assignor arising under this Agreement following such assignment. Any purported assignment by a Party of this Agreement, or any of such party’s rights or obligations hereunder, in violation of this Section 18 shall be void.

19. Waiver and Election of Remedies.

The failure of any party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered a waiver or deprive that party thereafter of the right to insist upon strict adherence to that term or any other term of this Agreement. All waivers must be in writing and signed by an authorized representative of the party against which such waiver is being sought. The pursuit by either party of any remedy to which it is entitled at any time or continuation of the Agreement despite a breach by the other shall not

be deemed an election of remedies or waiver of the right to pursue any other remedies to which it may be entitled.

20. Binding on Successors.

This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns to the extent assignment is permitted under this Agreement.

21. Independent Contractors.

It is the express intention of the parties that the relationship of Columbia and the Company shall be that of independent contractors and shall not be that of agents, partners or joint venturers. Nothing in this Agreement is intended or shall be construed to permit or authorize either party to incur, or represent that it has the power to incur, any obligation or liability on behalf of the other party.

22. Entire Agreement; Amendment.

This Agreement, together with the Exhibits, sets forth the entire agreement between the parties concerning the subject matter hereof and supersedes all previous agreements, written or oral, concerning such subject matter. This Agreement may be amended only by written agreement duly executed by the parties.

23. Severability.

In the event that any provision of this Agreement is held by a court of competent jurisdiction to be unenforceable because it is invalid, illegal or unenforceable, the validity of the remaining provisions shall not be affected, and the rights and obligations of the parties shall be construed and enforced as if the Agreement did not contain the particular provisions held to be unenforceable, unless such construction would materially alter the meaning of this Agreement. By way of example, but not by way of limitation, Sections 4i(i), 4i(ii) and 4i(iii) are intended by Company and Columbia to be severable from each other, such that if one clause is found to be unenforceable, the other clauses remain operative and in effect.

24. No Third-Party Beneficiaries.

Except as expressly set forth herein, the parties hereto agree that there are no third-party beneficiaries of any kind to this Agreement.

25. Governing Law.

This Agreement shall be governed by and construed in accordance with the internal substantive laws of the State of New York as applicable to agreements made and wholly performed within the State of New York, and without reference to the conflict or choice of laws principles of any jurisdiction. Unless otherwise separately agreed in writing, the parties agree that any and all claims arising under or related to this Agreement shall be heard and determined only in either the United States District Court for the Southern District of New York or in the courts of the State of New York located in the City and County of New York, and the parties irrevocably agree to submit themselves to the exclusive and personal

jurisdiction of those courts and irrevocably waive any and all rights any such party may now or hereafter have to object to such jurisdiction or the convenience of the forum.
