In the case of discounts on “bundles” of products or services which include Licensed Products and/or Licensed Services, LICENSEE may, with notice to MSK, discount (or permit the discounting by an Affiliate or Sublicensee of LICENSEE) the bona fide list price of any Licensed Product and/or Licensed Service in such “bundle” by the average percentage discount of all products and services in a particular “bundle,” calculated as follows: average percentage discount on a particular “bundle” = [1 - (A/B)] x 100; where A equals the total discounted price of a particular “bundle” of products and/or services, and B equals the sum of the undiscounted bona fide list prices of each unit of every product and/or services in such “bundle” (including without limitation, the Licensed Products and Licensed Services). With each quarterly royalty report submitted pursuant to Section 6.2 below, LICENSEE shall provide MSK reasonable documentation establishing such average discount with respect to each “bundle.” If LICENSEE cannot so establish the average discount of a “bundle,” Net Sales shall be based on the undiscounted list price of the Licensed Product or Licensed Service, as the case may be, in the “bundle.” If a the Licensed Product or Licensed Service in a “bundle” is not sold separately, and no bona fide list price exists for such the Licensed Product or Licensed Service, the Parties shall mutually agree (such agreement not to be unreasonably withheld by either Party) an imputed list price for such the Licensed Product or Licensed Service and Net Sales with respect thereto shall be based on such imputed list price.

Except as provided in the preceding paragraph, no deductions, credits, rebates, or allowances shall be taken or permitted in calculating Net Sales that depend or are based in whole or in part on the sale or purchase of any product or service that is not a Licensed Product or Licensed Service, including without limitation for the practice commonly known as “bundling.” In no case will Deductible Expenses exceed [****] of the gross proceeds or exceed [****] of the fair market value, attributable to Net product Sales. If a Licensed Product is sold, or a Licensed Service performed, for the purpose of creating a finished product for sale, for example a finished therapeutic product for administration to patients, Net Sales shall be calculated on the first arms’ length sale of such finished product, and the sale of the Licensed Product or Licensed Service for the purpose of creating the finished product for sale shall be excluded.

Net Sales shall be determined in accordance with GAAP, but not in any way that reduces the calculations of Net Sales provided herein.

[****] Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

Additionally, if LICENSEE or a Sublicensee uses a Licensed Product or a Licensed Process for its own internal purposes, or otherwise in a situation that is not related to development of Licensed Products or Licensed Services, then Net Sales shall also include an amount equal to the customary sale price charged to a third party for the same Licensed Product or Process. If there is no customary sale price, then the Net Sales shall be an amount equal to the fair market value.

1.22 “Patent Rights” shall mean the Antibody Patent Rights and the Multimerization platform Patent Rights.

1.23 “Phase I Trial” means the first phase of a clinical study involving the initial introduction of an investigational new drug into humans (generally, but not always, in the range of 20 to 30 subjects). Phase I studies are typically closely monitored and may be conducted in patients or normal volunteer subjects. These studies are designed to determine the metabolism and pharmacologic actions of the drug in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness that provides data capable of meeting statutory standards for marketing approval. During Phase I, sufficient information about the drug’s pharmacokinetics and pharmacological effects should be obtained to permit the design of well-controlled, scientifically valid, Phase II Trials. For example, “Phase I Trial” includes a human clinical study that satisfies the requirements of 21 C.F.R. § 312.21(a) in the United States, or an equivalent or counterpart of the foregoing in any other country or jurisdiction. For clarity, “Phase I Trial” includes both Phase Ia and Phase Ib trials.

1.24 “Phase II Trial” means the second phase of a clinical study, the principal purpose of which is to evaluate the effectiveness of the drug for a particular indication and to determine the common short term side effects and risks associated with the drug in patients with the disease target being studied, that provides data capable of meeting statutory standards for marketing approval. Phase II Trials usually involve no more than several hundred subjects. For example, “Phase II Trial” includes a human clinical study that satisfies the requirements of 21 C.F.R. § 312.21(b) in the United States, or an equivalent or counterpart of the foregoing in any other country or jurisdiction. For clarity, “Phase II Trial” includes both Phase IIa and Phase IIb trials.

1.25 “Phase III Trial” means the third phase of a clinical study involving expanded controlled and uncontrolled trials. They are performed after preliminary evidence suggesting effectiveness of the drug has been obtained, and are intended to gather the additional information about effectiveness and safety that is needed to evaluate the overall benefit-risk relationship of the drug and to provide an adequate basis for physician labeling, to support registration for a product or compound with the FDA and any FDA counterpart, and that provides data capable of meeting statutory standards for marketing approval. Phase III Trials usually include several hundred to several thousand subjects. For example, in the United States, “Phase III Trial” includes a human clinical study that satisfies the requirements of 21 C.F.R. § 312.21(c) in the United States, or an equivalent or

counterpart of the foregoing in any other country or jurisdiction. For clarity, “Phase III Trial” includes both Phase IIIa and Phase IIIb trials.

1.26 “Platform technologies” means platform technologies developed utilizing the Multimerization Platform Patent Rights and Know-How.

1.27 “Regulatory Approval” means, with respect to a nation or, where applicable, a multinational jurisdiction, such approvals, licenses, registrations or authorizations that are required to be obtained from a Regulatory Agency prior to the marketing and sale of a Licensed Product for use in the Field in such country or multinational jurisdiction (including, where applicable, pricing approvals necessary to obtain reimbursement).

1.28 “Regulatory Authority” means, with respect to any particular country or, where applicable, a multinational jurisdiction, the governmental authority, body, commission, agency or other instrumentality of such country or multinational jurisdiction (e.g., the EMEA with respect to the European Union), with the primary responsibility for the approval of pharmaceutical products before a Licensed Product can be tested, marketed, promoted, distributed or sold in such country or multinational jurisdiction, including such governmental bodies, if any, that have jurisdiction over the pricing of such pharmaceutical product. The term “Regulatory Agency” includes, without limitation, the USFDA, the European Medicines Agency, and the Japanese MHW.

1.29 “Royalty Term” shall mean, on a Licensed Product-by-Licensed Product or Licensed Service-by-Licensed Service basis and country-by-country basis, the period from the first commercial sale of such Licensed Product or provision of Licensed Service in such country until the later of: (a) expiration of the last Patent Rights covering such Licensed Product or provision of Licensed Service in such country; (b) expiration of any market exclusivity period granted by a regulatory agency with respect to such Licensed Product or provision of Licensed Service in such country; or (c) fifteen (15) years from the first commercial sale in such country.

1.30 “Royalty Year” shall mean each twelve (12) month period commencing January 1 and ending December 31 during the term of this Agreement; provided however, that: (a) the first Royalty Year shall be the period of time commencing with the Effective Date and ending on December 31, 2015; and (b) the last Royalty Year shall be the period of time commencing on January 1 of the year in which this Agreement expires or is terminated, and ending on the date of expiration or termination of this Agreement.

1.31 “Sponsored Research Agreement” means the agreement between LICENSEE and MSK containing the terms and conditions under which the sponsored research at MSK will be performed.

1.32 “Sublicensee” means any business entity to which an express sublicense has been granted under the Licensed Rights as further described under Article 3. or with respect to the Licensed Products pursuant to this Agreement. It a third-party wholesaler or distributor does not pay any consideration to LICENSEE for its wholesale or distributor rights, it shall not be considered a Sublicensee; and the resale by such wholesaler or distributor of such Licensed Products or Licensed Services shall not count towards Net Sales by a Sublicensee provided that a royalty is being paid by LICENSEE on the Net Sales of the amount of initial transfer to the wholesaler or distributor pursuant to Article 5.

1.33 “Term” shall mean the term of this Agreement which will commence on the Effective Date and expire upon the expiration of the last Royalty Term for any Licensed Product or Licensed Service, unless earlier terminated pursuant to the Article 16 of this Agreement.

1.34 “Territory” shall mean worldwide.

1.35 “Valid Claim” shall mean a claim of (i) an issued and unexpired patent included within the Patent Rights unless the claim has been held unenforceable or invalid by the final, un-reversed, and un-appealable decision of a court or other government body of competent jurisdiction, has been irretrievably abandoned or disclaimed, or has otherwise been finally admitted or determined to be invalid, unpatentable or unenforceable, whether through reissue, reexamination, disclaimer or otherwise, or (ii) a pending patent application included within the Patent Rights to the extent the claim continues to be prosecuted in good faith for a time period not to exceed [****] from its earliest asserted priority filing date.

Indemnitee for any legal or other expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, that if under applicable standards of professional conduct a conflict of interest exists between the Indemnitor and the Indemnitee in respect of such claim, such Indemnitee shall have the right to employ separate counsel (which shall be reasonably satisfactory to the Indemnitor) to represent such Indemnitee with respect to the matters as to which a conflict of interest exists and in that event the reasonable fees and expenses of such separate counsel shall be paid by such Indemnitor; provided, further, that the Indemnitor shall only be responsible for the reasonable fees and expenses of one separate counsel for such Indemnitee. If the Indemnitor assumes the defense of any Third Party Claim, the Indemnitee shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnitor. If the Indemnitor assumes the defense of any Third Party Claim, the Indemnitor will promptly supply to the Indemnitee copies of all correspondence and documents relating to or in connection with such Third Party Claim and keep the Indemnitee informed of developments relating to or in connection with such Third Party Claim, as may be reasonably requested by the Indemnitee (including, without limitation, providing to the Indemnitee on reasonable request updates and summaries as to the status thereof). If the Indemnitor chooses to defend a Third Party Claim, all Indemnitees shall reasonably cooperate with the Indemnitor in the defense thereof (such cooperation to be at the expense, including reasonable legal fees and expenses, of the Indemnitor). If the Indemnitor does not elect to assume control of the defense of any Third Party Claim within the [****] period set forth above, or if such good faith and diligent defense is not being or ceases to be conducted by the Indemnitor, the Indemnitee shall have the right, at the expense of the Indemnitor, after [****] Business Days’ notice to the Indemnitor of its intent to do so, to undertake the defense of the Third Party Claim for the account of the Indemnitor (with counsel selected by the Indemnitee), and to compromise or settle such Third Party Claim, exercising reasonable business judgment.

If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, the Indemnitee will agree to any settlement, compromise or discharge of such Third Party Claim that the Indemnitor may recommend that by its terms obligates the Indemnitor to pay the full amount of Losses (whether through settlement or otherwise) in connection with such Third Party Claim and unconditionally and irrevocably releases the Indemnitee completely from all liability in connection with such Third Party Claim; provided, however, that, without the Indemnitee’s prior written consent, the Indemnitor shall not consent to any settlement, compromise or discharge (including the consent to entry of any judgment), and the Indemnitee may refuse in good faith to agree to any such settlement, compromise or discharge, that provides for injunctive or other non-monetary relief affecting the Indemnitee. If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, the Indemnitee shall not (unless required by law) admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnitor’s prior written consent (which consent shall not be unreasonably withheld).

MSK reserves the right to publish the scientific findings from research related to Licensed Rights and clinical use of Licensed Products and Licensed Services. If any proposed publication (e.g., manuscript, abstract or other public disclosure), contains Confidential Information of LICENSEE or its Affiliates or Sublicensees, MSK will submit the abstract or manuscript to LICENSEE at least thirty (30) calendar days before public disclosure thereof, and LICENSEE shall have the right to review and comment upon the proposed public disclosure in order to protect such Confidential Information and the patentability of any inventions disclosed therein.

ARTICLE 16 - TERMINATION

16.1 Term. This Agreement commences on the Effective Date and shall remain in effect, until the end of the Royalty Term, as provided it Section 1.13 unless sooner terminated in accordance with the provisions herein.

16.2 Bankruptcy or Cessation/Enjoinder of Business. MSK may terminate this Agreement upon written notice to LICENSEE if: (a) LICENSEE becomes insolvent; (b) a petition in bankruptcy is filed against LICENSEE and is consented to, acquiesced in or remains undismissed for thirty (30) days; (c) LICENSEE or makes a general assignment for the benefit of creditors, or a receiver is appointed for LICENSEE, and LICENSEE does not return to solvency before the expiration of a thirty (30) day period; (d) LICENSEE ceases to do business: or (e) if the enactment of any law, decree, or regulation, or the issuance of any order (including, but not limited to, an injunction), by any governmental authority renders it impracticable or impossible for LICENSEE to perform any of its obligations hereunder.

16.3 Nonpayment. If LICENSEE fails to pay MSK fees, royalties, ongoing patent expenses or other amounts payable hereunder, and such payments remain past due for more than thirty (30) days, MSK shall have the right to terminate this Agreement on thirty (30) days prior written notice to LICENSEE, unless LICENSEE pays to MSK within the thirty (30) day notice period, all fees, royalties and patent expenses, together with any interest then due and payable thereon. If LICENSEE after such written notice makes such payment to avoid termination, and if LICENSEE’s obligation to make such payment was or becomes the subject of a good faith dispute between the Parties, such payment shall be returned to LICENSEE by MSK if a final, unappealable judgment in an action commenced within six months of LICENSEE’s making of said payment determines in favor of LICENSEE what such payment was not owed.

16.4 Criminal Activity. MSK may terminate this Agreement upon immediate written notice to LICENSEE if LICENSEE is convicted in a final judgment of a felony relating to the manufacture, use, or sale of Licensed Products in any jurisdiction where LICENSEE manufactures, uses or sells Licensed Products; provided, no such termination may be made until any appeal(s) of such conviction are exhausted and only then if such conviction is not reversed.

16.5 Breach, in addition to any other termination right specified in this Agreement, MSK may terminate this Agreement upon [****] prior written notice to LICENSEE, if LICENSEE materially breaches a provision of this Agreement, unless:

(a) LICENSEE cures any such breach prior to the expiration of the [****] period; or

(b) LICENSEE has taken reasonable steps to cure such breach prior to the expiration of [****] cure period and has demonstrated to MSK’s reasonable satisfaction that such breach, is likely to be cured within a reasonable time thereafter not to exceed [****] days, or

(c) before the end of the [****] day cure period, LICENSEE notifies MSK that it has failed to achieve any of the Milestone Activities described herein within the timeframes specified due to causes that are beyond the reasonable control of LICENSEE (e.g., regulatory action or delay, low patient enrollment, Force Majeure Event, and/or delays caused by MSK), notwithstanding LICENSEE’s reasonable, good faith efforts to achieve those Milestone Activities, then LICENSEE will not be deemed in default or breach of this Agreement and the timeframe for achieving those milestones will be deemed automatically extended by the time of the delay reasonably attributable to the causes that were beyond LICENSEE’s control as long as LICENSEE diligently and continuously pursues the achievement of such milestones, but in no event shall such extension be longer than [****].

16.6 Termination by LICENSEE. LICENSEE may terminate this Agreement in its entirety without cause on [****] days’ notice to MSK; provided, however, once the performance of marketing, manufacture, sales, distribution and support activities of a Licensed Product and/ or Licensed Service (“Commercialization”) have commenced, LICENSEE may terminate this Agreement with such notice only if all Commercialization activities of LICENSEE, Sublicencees, and their Affiliates have been permanently discontinued.

16.8 Dispute Resolution. The Parties shall negotiate all matters of joint concern in good faith, with the intention of resolving issues between them in a mutually satisfactory manner, including, without limitation, the achievement of any Milestone Activities on or prior to any Expected Completion Date, under Article 4 of this Agreement. If a disagreement between the Parties cannot be resolved through informal discussions, it shall be deemed a “Dispute” upon one party (the

“Declaring Party”) declaring, by the delivery of a written notice (the “Notice”) to the other party, that a Dispute exists. The Notice shall specify the nature and cause of the Dispute and the action that the Declaring Party deems necessary to resolve the Dispute. Following receipt of the Notice, the Parties shall use good faith efforts to resolve the Dispute within [****] of the date of such Notice, including making personnel with appropriate decision-making authority available to the other Party to discuss resolution of the Dispute. In the event Dispute cannot be resolved by mutual agreement within such [****] period, the Parties may, by the election of either Party, submit the Dispute to non-binding dispute resolution before a mediator expert in the field, selected by mutual agreement within [****] of a written request for mediation submitted by either Party. Said mediation shall be held in the County of New York, State of New York, at such place as shall be mutually agreed upon by the Parties.

16.9 Effect on Sublicensees. All sublicenses, and rights of Affiliates and Sublicensees, will terminate as of the effective date of termination of this Agreement, provided, however, that if at the effective date of termination any Sublicensee is in good standing with regard to its obligations under its sublicense and agrees to assume the applicable obligations of LICENSEE hereunder, then, at the request of the Sublicensee, such sublicense shall survive such termination or expiration of this Agreement and be assigned to MSK with respect to the Licensed Product, Licensed Services, and Licensed Rights; provided, in such case the obligations of MSK to Sublicensee shall not exceed the obligations of MSK to LICENSEE under the Agreement.

(a) any provision expressly indicated to survive;

LICENSEE agrees to legibly ▇▇▇▇ the Licensed Products (and packaging, marketing materials, package inserts, patient information leaflets, and other documentation therefore) sold in the United States with all applicable United States patent numbers, and other notices relating to MSK’s Patent Rights, such markings and notices to be in accordance with any written guidelines that

may be provided by MSK from time to time. All Licensed Products shipped to or sold in other countries shall be marked in such a manner as to conform to the patent laws and practice of the country of manufacture or sale. In connection with such patent marking, LICENSEE shall also include a statement that the Licensed Product is made under license from MSK.

18.4 Waiver. The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other party.

18.5 Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be an original and all such counterparts shall together constitute but one and the same agreement.

18.6 Force Majeure Event.
