If any Other Active included in the Bundle is not sold alone, Net Sales shall be calculated by multiplying Net Sales of such Bundle by X/W where: X is as defined above; and W is the average sales price during the applicable reporting period for such Bundle. If neither (1) the Product containing only a Licensed Compound or Program Compound nor (2) products containing only Other Actives in the Bundle are sold separately (in the same dosage form), the Parties will discuss in good faith to determine an equitable fair market price to apply to calculate the Net Sales of such Product and the Other Active(s) in the Bundle.

RBNC shall not attempt to reduce compensation rightly due to AMGEN under this Section 3.3 (Sublicensing Income) by shifting compensation otherwise payable to RBNC from a Third Party with respect to the Product to another product or service for which no amounts are payable under this Section 3.3 (Sublicensing Income).

Section 3.4 Method of Payment . Unless otherwise agreed by the Parties, all payments due from RBNC to AMGEN under this Agreement shall be paid in United States Dollars by wire transfer or electronic funds transfer of immediately available funds to the following account:

Beneficiary Name: [***]

Beneficiary Account #: [***]

Bank Name: [***]

ABA#: [***]

Swift Code: [***]

Section 3.5 Royalty Reports . After the First Commercial Sale of the first Product and until expiration of the last Royalty Term, RBNC shall prepare and deliver to AMGEN royalty reports of the sale of the Products by the Selling Parties for each Calendar Quarter within [***] days of the end of each such Calendar Quarter specifying in the aggregate and on a Product-by-Product and country-by-country basis: (a) total gross amounts for each Product sold or otherwise disposed of by a Selling Party; (b) amounts deducted by category in accordance with the definition of “Net Sales” in Article 1 (Definitions) from gross amounts to calculate Net Sales; (c) Net Sales; and (d) royalties payable.

Section 3.6 Clarification of Products. For purposes of this Article 3, one Product shall be deemed different from another Product if a new IND is required to be filed to conduct a clinical trial of such other Product.

Section 3.7 Currency Conversion. With respect to Net Sales invoiced in U.S. Dollars, such Net Sales invoiced shall be expressed in U.S. Dollars. With respect to Net Sales invoiced in a currency other than U.S. Dollars, such Net Sales invoiced shall be converted into the U.S. Dollar equivalent using a rate of exchange which corresponds to the rate used by the Selling Party in recording such receipt, for the respective reporting period, related to recording such Net Sales in its books and records that are maintained in accordance with Accounting Standards. If a Selling Party is not required to perform such currency conversion for its Accounting Standards reporting with respect to the applicable period, then for such period such Selling Party shall convert its amounts received incurred into U.S. Dollars using a rate of exchange which corresponds to the noon buying rate as published in the Wall Street Journal, Eastern U.S. Edition on the second to last business day of the Calendar Quarter (or such other publication as agreed-upon by the Parties). Any royalty amount shall be calculated based upon the U.S. Dollar equivalent calculated in accordance with the foregoing.

-21-

Section 3.8 Late Payments. In the event that any payment due hereunder is not made when due, the payment shall accrue interest beginning on the day following the due date thereof, calculated at the annual rate of the sum of (a) [***] plus (b) the prime rate effective for the date that payment was due, as published by the Wall Street Journal, Eastern U.S. Edition, the interest being compounded on the last day of each Calendar Quarter; provided, however, that in no event shall said annual interest rate exceed the maximum rate permitted by Law. Each such payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of any Party to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment including, but not limited to termination of this Agreement as set forth in Article 10 (Term & Termination). The Parties will use good faith efforts to reconcile any disputed amounts of payments due hereunder as soon as practicable.

Section 3.9 Records and Audits. RBNC will keep complete and accurate records of the underlying revenue and expense data relating to the calculations of Net Sales generated in the then current Calendar Year and payments required under this Agreement, and during the preceding [***] Calendar Years. AMGEN will have the right, [***] at its own expense, to have a nationally recognized, independent, certified public accounting firm, selected by it and subject to RBNC’s prior written consent (which shall not be unreasonably withheld), review any such records of RBNC and its Affiliates and Sublicensees (the “Audited Party”) in the location(s) where such records are maintained by the Audited Party upon reasonable written notice (which shall be no less than [***] days’ prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the basis and accuracy of payments made under Section 3.2 (Royalties) within the [***] month period preceding the date of the request for review. No Calendar Year will be subject to audit under this Section 3.9 more than once. RBNC will receive a copy of each such report concurrently with receipt by AMGEN. Should such inspection lead to the discovery of a discrepancy to AMGEN’s detriment, RBNC will, within [***] days after receipt of such report from the accounting firm, pay any undisputed amount of the discrepancy together with interest at the rate set forth in Section 3.8 (Late Payments). AMGEN will pay the full cost of the review unless the underpayment of amounts due to AMGEN is [***] of the amount due for the entire period being examined, in which case RBNC will pay the cost charged by such accounting firm for such review. Should the audit lead to the discovery of a discrepancy to RBNC’s detriment, RBNC may credit the amount of the discrepancy, without interest, against future payments payable to AMGEN under this Agreement, and if there are no such payments payable, then AMGEN shall pay to RBNC the amount of the discrepancy, without interest, within [***] days of AMGEN’s receipt of the report.

Section 3.10 Taxes.

3.10.1 Sales Tax. RBNC is responsible for the payment of any state or local, sales or use, or similar fees or taxes arising as a result of the transfer of Licensed Materials by AMGEN to RBNC pursuant to Section 2.5 (Transfer of Licensed Know-How and Licensed Materials), and RBNC will remit such fees or taxes to the appropriate tax collector. The Parties shall cooperate in accordance with Law to minimize any such taxes imposed or required to be paid in connection with this Agreement, and if any such taxes are owed, provide reasonable assistance to obtain a refund or credit of the taxes paid.

-22-

3.10.2 Withholding. RBNC shall be entitled to deduct and withhold from any amounts payable under this Agreement such taxes as are required to be deducted or withheld therefrom under any provision of Law. In the event that any Law requires RBNC to withhold taxes with respect to any payment to be made by RBNC pursuant to this Agreement, RBNC will use commercially reasonable efforts to notify AMGEN of such withholding requirement prior to making the payment to AMGEN and cooperate with AMGEN, including by providing standard documentation as may be required by a tax authority, as may be reasonably necessary in AMGEN’s efforts to claim an exemption from or reduction of such taxes. RBNC will, in accordance with such Law withhold taxes from the amount due, remit such taxes to the appropriate tax authority, and furnish AMGEN with proof of payment of such taxes within [***] days following the payment. If any such taxes are paid to a tax authority, RBNC shall use commercially reasonable efforts to provide reasonable assistance to AMGEN to obtain a refund of such taxes withheld, or obtain a credit with respect to such taxes paid. Any such amounts deducted and withheld shall be treated for all purposes of this Agreement as having been paid to the party in respect of whom such deduction and withholding was made. On or prior to the Effective Date, AMGEN will provide RBNC with a completed and duly executed IRS Form W-9.

3.10.3 VAT. All payments due to AMGEN from RBNC pursuant to this Agreement shall be paid exclusive of any value-added tax (“VAT”) (which, if applicable, shall be payable by RBNC upon receipt of a valid VAT invoice). If AMGEN determines that it is required to report any such tax, RBNC shall promptly provide AMGEN with applicable receipts and other documentation necessary or appropriate for such report. For clarity, this Section 3.10.3 (VAT) is not intended to limit RBNC’s right to deduct value-added taxes in determining Net Sales.

3.10.4 Tax Treatment of Payments.

(a) AMGEN and RBNC intend to treat the payment of any Sublicense Consideration, Milestone Payments and any royalties pursuant to this Article 3 as consideration for the licenses granted hereunder to RBNC for U.S. federal income tax purposes (and applicable state, local or non-U.S. Tax purposes).

(b) AMGEN and RBNC shall file all Tax returns, reports, schedules, information statements and other documents consistently with the understandings set forth in this Section 3.10.4, and shall take no contrary position on any such Tax return, or in any audit, claim, investigation or proceeding in respect of Taxes unless otherwise required pursuant to a final determination within the meaning of Section 1313 of the Code, or any analogous provision of applicable state, local or non-U.S. law.

With respect to Joint Inventions and Joint Patents, to the extent necessary to effect the foregoing in a country other than the United States, each Party hereby grants to the other Party a non-exclusive, irrevocable, perpetual, fully-paid (except as expressly stated in this Agreement), worldwide license, with the right to grant sublicenses, under the granting Party’s interest in Joint Inventions and Joint Patents, for any and all purposes. Inventorship and authorship of any Invention or work of authorship conceived or created by either Party or jointly by the Parties pursuant to this Agreement, shall follow the rules of the U.S. Patent and Trademark Office and the Laws of the U.S., respectively (without reference to any conflict of law principles).

4.1.2 Notwithstanding anything to the contrary in Section 4.1.1, all right, title, and interest in and to Sole Inventions and Joint Inventions exclusively related to Program Compounds (collectively, “Program Compound Inventions”) (and any associated Patent Rights) shall be owned exclusively by RBNC regardless of inventorship. AMGEN shall and hereby does assign to RBNC all of AMGEN’s right, title and interest in and to any such Program Compound Inventions developed solely by or on behalf of AMGEN or jointly by the Parties pursuant to this Agreement, including all Patent Rights claiming such Program Compound Inventions.

4.3.1 RBNC shall have the first right, but not the obligation, to file, prosecute and maintain all Patent Rights in the Program Patents, Licensed Patents and Joint Patents, and Patent Rights claiming any Licensed Know-How or Sole Inventions conceived or created by or on behalf of AMGEN relating directly to the composition of a Licensed Compound, at RBNC’s sole expense using outside counsel reasonably acceptable to AMGEN. AMGEN shall reasonably cooperate with RBNC’s requests for data, affidavits, and other information and assistance to support prosecution and maintenance of the Patent Rights in the Program Patents, Licensed Patents and Joint Patents; provided, however, that RBNC shall reimburse AMGEN for its reasonable, documented out-of-pocket expenses with respect to such cooperation. RBNC shall promptly upon receipt forward to AMGEN copies of any significant office actions, communications, and correspondence relating to the Program Patents, Licensed Patents and Joint Patents. AMGEN shall have the right to comment on and to discuss prosecution and maintenance activities with RBNC, and RBNC shall consider the same in good faith and shall provide AMGEN with copies of all such proposed filings and correspondence relating to the Program Patents, Licensed Patents and Joint Patents to give AMGEN the opportunity to review and comment.

4.3.2 Notwithstanding the foregoing, if RBNC, its Affiliate or Sublicensee declines to file, prosecute or maintain any Patent Rights under Section 4.3.1 in (1) Program Patents that claim the composition of matter of Licensed Compounds or derivatives thereof Directed to CK1d, (2) Licensed Patents, (3) Joint Patents , or Patent Rights claiming any Licensed Know-How or Sole Inventions conceived or created by or on behalf of AMGEN to the extent relating directly to the composition of a Licensed Compound, or elects to allow any such Patent Rights to lapse in any country, or elects to abandon any such Patent Rights before all appeals within the respective patent office have been exhausted (each, an “Abandoned Patent Right”), then:

(a) RBNC shall provide AMGEN with reasonable notice of such decision so as to permit AMGEN to decide whether to file, prosecute or maintain such Abandoned Patent Rights and to take any necessary action (which notice shall, in any event, be given no later than [***] days prior to the next deadline for any action that may be taken with respect to such Abandoned Patent Right with the U.S. Patent & Trademark Office or any foreign patent office).

(b) AMGEN, at AMGEN’s expense, may assume control of the filing, prosecution and/or maintenance of such Abandoned Patent Rights.

(c) AMGEN shall have the right to transfer the responsibility for such filing, prosecution and maintenance of such Abandoned Patent Rights to patent counsel (outside or internal) selected by AMGEN.

(d) RBNC shall assist and cooperate with AMGEN’s reasonable requests to support prosecution and maintenance of such Abandoned Patent Rights; provided, however, that AMGEN shall reimburse RBNC for its reasonable expenses with respect to such cooperation (including RBNC’s employee’s time at the FTE Rate).

Each Party will notify the other promptly in writing when any Infringement of a Licensed Patent, Program Patent or Joint Patent by a Third Party is uncovered or reasonably suspected in connection with compounds or products that are Directed to CK1d. RBNC shall have the first right to enforce any patent within the Licensed Patents, Program Patents or Joint Patents against any such Infringement or alleged Infringement thereof, and shall at all times keep AMGEN informed as to the status thereof. RBNC may, at its own expense, institute suit against any such infringer or alleged infringer and control and defend and settle such suit in a manner consistent with the terms and provisions hereof and recover any damages, awards or settlements resulting therefrom, subject to Section 4.6 (Recovery).

4.4.2 AMGEN Enforcement. If RBNC (directly or through an Affiliate or Sublicensee) elects not to enforce any patent within the Licensed Patents, Program Patents or Joint Patents, then it shall so notify AMGEN in writing within [***] months of receiving notice that such an Infringement exists (or such shorter period as may be necessary to prevent exhaustion of a statute of limitations (or laches) applicable to such Infringement), and AMGEN may, in its sole judgement, and at its own expense, take steps to enforce any such patent, and control, settle, and defend such suit in a manner consistent with the terms and provisions hereof, and recover any damages, awards or settlements resulting therefrom, subject to Section 4.6 (Recovery). RBNC shall reasonably cooperate in any such litigation (including joining or being named a necessary party thereto) at AMGEN’s expense.

Section 4.5 Defense of Third Party Claims. If either (a) any Product Exploited by or under authority of RBNC becomes the subject of a Third Party’s claim or assertion of Infringement of a patent relating to the manufacture, use, sale, offer for sale or importation of such Product in the Licensed Field in the Territory, or (b) a declaratory judgment action is brought naming

-26-

either Party as a defendant and alleging invalidity or unenforceability of any of the Licensed Patents, Program Patents or Joint Patents, the Party first having notice of the claim or assertion shall promptly notify the other Party, and the Parties shall promptly confer to consider the claim or assertion and the appropriate course of action. Subject to Article 7 (Indemnification), unless the Parties otherwise agree in writing, (i) with respect to claims or assertions in Section 4.5(a), each Party shall have the right to defend itself against a suit that names it as a defendant at its expense, and (ii) with respect to actions in Section 4.5(b) alleging invalidity or unenforceability of any Licensed Patent, Program Patent or Joint Patent, RBNC shall have the first right, but not the obligation, directly or through an Affiliate or Sublicensee, to defend and control the defense of any such action at its expense, and if RBNC elects not to or fails to defend or control the defense of such action, then AMGEN may conduct and control the defense of such action at its expense. Neither Party shall enter into any settlement of any claim described in this Section 4.5 that admits to the invalidity or unenforceability of the Licensed Patents, Program Patents or Joint Patents, incurs any financial liability on the part of the other Party, requires an admission of liability, wrongdoing or fault on the part of the other Party, without the other Party’s prior written consent, in each case such consent not to be unreasonably withheld.

Section 4.8 Patent Marking. RBNC will mark, and will cause all other Selling Parties to mark, the Products with all Joint Patents in accordance with applicable Law, which marking obligation will continue for as long as (and only for as long as) required under applicable Law.

ARTICLE 5. OBLIGATIONS OF THE PARTIES

Section 5.1 Responsibility. Following the Effective Date and at all times during the Term (except as expressly stated otherwise herein), RBNC shall be solely responsible for, and shall bear all costs associated with, the Exploitation of the Licensed Compounds, Program Compounds and Products in the Licensed Field in the Territory, including regulatory,

-27-

manufacturing, distribution, marketing and sales activities. Subject to the express written terms of this Agreement, all decisions concerning the development, marketing and sales of Products in the Licensed Field in the Territory including the clinical and regulatory strategy, design, sale, price and promotion of Products covered under this Agreement shall be within the sole discretion of RBNC.

Section 5.2 Diligence. RBNC shall (directly and/or through one or more Affiliates and/or Sublicensees) use Commercially Reasonable Efforts to develop, manufacture, obtain Marketing Approval and commercialize at least one (1) Product. RBNC shall notify AMGEN immediately upon obtaining Marketing Approval for a Product in each country.

Section 5.3 Reports. Within [***] days of the beginning of each Calendar Year, with respect to each Product until the first commercial sale of such Product, RBNC shall submit to AMGEN a [***] providing the status of RBNC’s and its Affiliates’ and Sublicensees’ activities related to the research and development of and Marketing Approval for such Products during the [***], and plans for future activities related to the research and development of and Marketing Approval for such Products [***], in each case in relation to the last updated development plan including any updates to the clinical plans. In addition, with respect to each Phase II Clinical Trial completed for any Product during the ROFN Period, as promptly as practicable following completion of such Clinical Trial, RBNC shall prepare and deliver to Amgen the Clinical Trial Report with respect to such Phase II Clinical Trial.

Section 5.4 Distracting Programs.

5.4.1 Distracting Programs. Except as set forth in Section 5.4.2 (RBNC Election), Section 5.4.3 (Post-Effective Date Affiliates) and Section 5.4.4 (Termination or Divestiture), during the Term until the [***] anniversary of the First Commercial Sale of the first Product in the United States, RBNC shall not (and shall ensure its Affiliates and Sublicensees do not) (a) directly, or indirectly with or through a Third Party, conduct or participate in any Distracting Program, or (b) enable a Third Party, by granting a license, sublicense or other rights to such Third Party, to conduct or participate in any Distracting Program. For clarity, any failure of any RBNC Affiliate or Sublicensee to comply with this Section 5.4.1 shall be deemed a breach by RBNC.

5.4.2 RBNC Election.

(a) Distracting Program. In the event that RBNC or its Affiliate or its Sublicensee gains rights to a Distracting Program, then RBNC shall provide prompt written notice (in all events within [***] days of gaining such rights) to AMGEN and include in such notice whether RBNC elects to treat all Distracting Product(s) that are the subject of such Distracting Program as “Product(s)” under this Agreement.

(b) De Novo Compounds. In the event that RBNC or its Affiliate or its Sublicensee gains rights to Exploit a De Novo Compound or De Novo Product, then RBNC shall provide prompt written notice (promptly following the later of such acquisition or the filing of any patent application with respect to a De Novo Compound or De Novo Product, and in all cases before any Licensed Know How is used or practiced in connection with such De Novo Compound or De Novo Product) to AMGEN and include in such notice whether RBNC elects to treat any such De Novo Compound and related De Novo Product as a “Product” under this Agreement.

-28-

(c) Newly Added Products. If RBNC makes an election in the notice provided to AMGEN pursuant to Section 5.4.2(a) or Section 5.4.2(b) to treat a Distracting Product (including, for clarity, a De Novo Product) as a “Product”, then any such Distracting Product (including, for clarity, a De Novo Product) will thereafter be considered a “Product” for purposes of this Agreement (a “Newly Added Product”) and would cease to be considered a “Distracting Product” giving rise to a “Distracting Program” that is prohibited under Section 5.4.1. The Parties acknowledge and agree that, notwithstanding anything to the contrary herein, products containing RBNC Compounds are deemed Newly Added Products as of the Effective Date. RBNC’s (or its Affiliate’s or its Sublicensee’s) exploitation of the Newly Added Product would be subject to all diligence and reporting obligations under this Agreement as well as Milestone Payment and royalty obligations contemplated under this Agreement in each case from and after the time such Product becomes a Newly Added Product (for clarification, there shall be no obligation to make any back-payment of Milestone Payments that would have been triggered by such Newly Added Product had such Newly Added Product been considered a “Product” at the time such Milestone occurred). Any Patent Rights controlled by RBNC or its Affiliates or its Sublicensees (including, for clarity, any in-licensed Patent Rights) Covering such Newly Added Product would be considered “Program Patents” for purposes of determining the Royalty Term, royalties, and royalty reductions applicable to such Newly Added Product.

5.4.3 Post-Effective Date Affiliates. In the event that RBNC or its Affiliates or Sublicensees enters into a Distracting Transaction with a Third Party (and for clarity, RBNC has not elected to treat such Distracting Product as a Newly Added Product pursuant to Section 5.4.2), then RBNC shall provide prompt written notice to AMGEN. Until the provisions of Section 5.4.4 (Termination or Divestiture) are effectuated, RBNC (or its Sublicensee) shall ensure that information and materials relating to the Products or activities hereunder are not shared with or used for the benefit of, and are sequestered from, Distracting Transaction Affiliate(s).

5.4.4 Termination or Divestiture. The notice provided pursuant to Section 5.4.3 (Post-Effective Date Affiliates) shall include a notification as to whether RBNC (or its Affiliate or Sublicensee) intends to: (a) Divest the Distracting Program, in which case [***]; or (b) terminate such Distracting Program, in which case [***] or (c) in the case of a Sublicensee, terminate the Sublicense Agreement with respect to the Product [***]. In the event RBNC (or its Affiliate or Sublicensee) elects to Divest the Distracting Program under subsection (a) [***], then (i) [***] or (ii) [***].

Section 5.5 Reasonable Restrictions. Each of the Parties acknowledges that the provisions of Section 5.4 (Distracting Programs) are reasonable and necessary to protect the legitimate interests of the other Party and to encourage the free sharing of information between the Parties with respect to the Products and each of the Parties agrees not to contest such limitations in any proceeding.

-29-

Section 5.6 Exclusivity. During the Term until [***], AMGEN will not and will ensure its Affiliates do not (a) directly, or indirectly with or through a Third Party, [***].

Section 5.7 Filings, Consents and Approvals

In addition, except as may be prohibited by any Governmental Authority or by any applicable Law each Party hereto will permit authorized representatives of the other Parties to be present at each meeting or telephone call and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Authority in connection with such communication, request or proceeding.

5.7.3 Subject to the terms and conditions of this Agreement, each of AMGEN and RBNC shall use its Commercially Reasonable Efforts to take, or cause to be taken, all other actions and do, or cause to be done, all other things necessary, proper or advisable under applicable Law to consummate the transactions contemplated by this Agreement, including (i) making all filings and submissions under the HSR Act, to the extent required, as promptly as practicable after the date hereof and (ii) obtaining as promptly as practicable the expiration of any waiting period under the HSR Act, if applicable.

5.7.4 Notwithstanding anything in this Agreement to the contrary, it is expressly understood and agreed that: (i) neither AMGEN nor RBNC shall have any obligation to litigate or contest any administrative or judicial action or proceeding or any decree, judgment, injunction or other order, whether temporary, preliminary or permanent; and (ii) neither AMGEN nor RBNC shall be under any obligation to make proposals, execute or carry out agreements, enter into consent decrees or submit to orders providing for (a) the sale, divestiture, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of AMGEN or RBNC or any of their subsidiaries, or (b) the imposition of any limitation or regulation on the ability of AMGEN or RBNC to freely conduct their business or own such assets.

Section 9.1 Term. Except for the terms and conditions of Article 6 (Representations), Article 7 (Indemnification), Article 8 (Confidentiality), Article 10 (Miscellaneous), and Section 5.7 (Filings, Consents and Approvals) which shall become effective on the Execution Date, this Agreement shall become effective on the Closing Date (such date, the “Effective Date”); provided, however, in the event that the Effective Date does not occur within [***] days of the Execution Date, either Party will have the right to terminate this Agreement in its entirety immediately upon notice to the other Party; provided, further, such notice of termination is delivered to the other Party before the date on which the Parties obtain all necessary antitrust or competition law clearances, consents and approvals for the closing of this Agreement.

Section 9.5 Effects of Termination for Licensed Compounds, Program Compounds and Products that are not RBNC Compounds. Upon termination by either Party under Section 9.2 (Termination by AMGEN), Section 9.3 (Termination by RBNC) or Section 9.4 (Termination Upon Bankruptcy), with respect to Products containing Licensed Compounds or Program Compounds other than RBNC Compounds:

(a) RBNC will responsibly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices and all legal and regulatory requirements, any on-going clinical studies for which it has responsibility hereunder in which patient dosing has commenced or, if reasonably practicable and not adverse to patient safety and requested by AMGEN, RBNC shall complete such trials and AMGEN shall reimburse RBNC its reasonable, out-of-pocket costs and internal labor costs at the FTE Rate associated therewith. For the purpose of clarity, except as provided for above, RBNC may wind-down any ongoing clinical trials prior to the date of termination in accordance with accepted pharmaceutical industry norms and ethical practices and RBNC will be responsible for any costs associated with such wind-down.

(b) Such termination of this Agreement will automatically terminate any sublicense granted by RBNC pursuant to Section 2.2 (Sublicenses) unless AMGEN has approved such sublicense in writing, in which case all rights under such sublicense shall be deemed to survive termination as long as Sublicensee complies with its obligations thereunder, and provided further that in no event will AMGEN be obligated to fulfill any of RBNC’s obligations under such sublicense that extend beyond the obligations of AMGEN set forth in this Agreement.

(c) All rights and licenses granted by AMGEN to RBNC in Article 2 (License Grant) will terminate, and RBNC and its Affiliates, and (subject to Section 9.5(b)) Sublicensees will cease all use of Licensed Know-How and Licensed Patents and all Exploitation of any such Licensed Compound, Program Compound or Product, except to the extent required hereunder.

(d) Upon AMGEN’s request, all Marketing Approvals and other Regulatory Filings and communications owned (in whole or in part) or otherwise Controlled by RBNC and its Affiliates, and (subject to Section 9.5(b)) Sublicensees, and all other documents relating to or necessary to further Exploit any such Product, as such items exist as of the effective date of such termination (including all documents related to completed and ongoing clinical studies) will be assigned to AMGEN to the extent practicable (or, if not so assigned, RBNC shall make the benefit of the foregoing reasonably available to AMGEN), and RBNC will provide to AMGEN one (1) copy of the foregoing and all documents contained in or referenced in any such items, together with the raw and summarized data for any clinical studies (and where reasonably available, electronic copies thereof). All expenses in relation to such assignment will be borne by AMGEN. In the event of any failure to obtain assignment, RBNC hereby consents and grants to AMGEN the right to access and reference (without any further action required on the part of RBNC, whose authorization to file this consent with any Regulatory Authority is hereby granted) any such item.

-43-

(e) Upon AMGEN’s election, RBNC shall and hereby does grant to AMGEN and its Affiliates (i) an automatic, worldwide, perpetual and irrevocable exclusive license, with the right to grant sublicenses through multiple tiers, solely for use in Exploiting such Products, under Know-How and Patent Rights that are Controlled by RBNC or any of its Affiliates (including any Know-How and Patent Rights Controlled by RBNC or its Affiliates through an assignment or license by Sublicensees) prior to termination and that Cover such Products and which are necessary for Exploiting any such Product as such Product exists as of the termination date, and (ii) an automatic, worldwide, perpetual and irrevocable non-exclusive license, with the right to grant sublicenses through multiple tiers, solely for use in Exploiting such Products, under Know-How and Patent Rights that are Controlled by RBNC or any of its Affiliates (including any Know-How and Patent Rights Controlled by RBNC or its Affiliates through an assignment or license by Sublicensees) prior to termination and that do not Cover such Products but that are necessary for Exploiting any such Product as such Product exists as of the termination date. RBNC shall use its reasonable efforts to facilitate a smooth, orderly and prompt transition of the Exploitation of any Product that is the subject of the license grant to AMGEN under this Section 9.5(e) from RBNC to AMGEN, promptly upon AMGEN’s election to take such a license. For the purpose of clarity, upon AMGEN’s election at the time of termination, (1) such license shall be effective only as of and after the effective date of such termination and (2) in consideration of such license, AMGEN will be obligated to pay to RBNC royalties during the Royalty Term(s) at rates that are [***] of the royalty rates contemplated in Section 3.2.1 (Royalty Rate; Royalty Term); provided, all deductions and reductions contemplated in Section 3.2 will apply to such payments, and the definition of Net Sales and Sections 3.4 (Method of Payment) to 3.10 (Taxes) (inclusive) will apply mutatis-mutandis to AMGEN in connection with the payment of such royalties. Notwithstanding the foregoing, in the event that any of the foregoing Know-How or Patent Rights are not Controlled by RBNC (or any of its Affiliates) due to the fact that RBNC (or its Affiliate) would be obligated to make any payments to a Third Party in connection with the grant of the foregoing licenses, then AMGEN shall have the right to assume such payment obligations and should it elect to do so and complies with such payment obligations, such Know-How and Patent Rights shall be included in such license grant.

(f) Upon AMGEN’s request, RBNC will assign (or, if applicable, will cause its Affiliates or (subject to Section 9.5(b)) Sublicensees to assign) to AMGEN all of RBNC’s (and such Affiliates’ and Sublicensees’) right, title and interest in and to any registered or unregistered trademarks or internet domain names that are specific to such Product(s), provided that such assignment is in accordance with RBNC’s policy on trademarks (it being understood that the foregoing will not include any trademarks or internet domain names that contain the corporate or business name(s) of RBNC).

-44-

(g) RBNC agrees (and shall cause its Affiliates and Sublicensees as a condition of the grant of the applicable sublicense to so agree) to fully cooperate with AMGEN and its designee(s) to facilitate a smooth, orderly and prompt transition of the Exploitation of such Products in the Territory to AMGEN and/or its designee(s). Upon request by AMGEN, RBNC shall transfer to AMGEN some or all quantities of such Products in its possession at [***] price paid by RBNC to a Third Party for such quantities or [***] plus [***]. If RBNC is, at the time of such termination of this Agreement, party to any Third Party contracts with respect to such Product(s), then it shall provide AMGEN notice of and (to the extent permitted to do so) copies thereof. RBNC shall assign to AMGEN any such contracts requested by AMGEN, to the extent solely relating to such Product(s) and to the extent it has the right under such contract(s) to do so (and shall use commercially reasonable efforts to obtain any required consents, which efforts shall not require making any payments or incurring any liabilities unless AMGEN agrees to reimburse RBNC therefor (and RBNC shall inform AMGEN of any such required payment or liability)). In addition, RBNC shall, at AMGEN’s cost and expense, (i) provide any cooperation reasonably requested by AMGEN to ensure uninterrupted supply of such Product(s) (including RBNC’s employees’ time at the FTE Rate), and (ii) if RBNC manufactured such Product(s) at the time of termination, continue to provide for manufacturing of such Product for AMGEN, at [***] of the fully-burdened manufacturing cost therefor, from the date of notice of such termination until the sooner to occur of such time as AMGEN is able, using commercially reasonable efforts to do so, to secure an acceptable alternative commercial manufacturing source from which sufficient quantities of such Product(s) may be procured and legally sold in the Territory or [***] months from the effective date of termination of this Agreement.

(h) Each Party shall, at Disclosing Party’s written request and election, either (i) destroy all copies of Disclosing Party’s Confidential Information relating to such Products in the possession or control of Receiving Party and confirm such destruction in writing to Disclosing Party, or (ii) return to Disclosing Party, at Disclosing Party’s expense, all copies of Disclosing Party’s Confidential Information relating to such Products in the possession or control of Receiving Party. Notwithstanding the foregoing, Receiving Party shall be permitted to retain (1) such Confidential Information to the extent necessary for purposes of performing any continuing obligations or exercising any ongoing rights under this Agreement, (2) a single copy of such Confidential Information for archival purposes, and (3) such Confidential Information that is contained in any computer records or files that have been created solely by Receiving Party’s automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with Receiving Party’s standard archiving and back-up procedures; provided that, in each case of (1), (2) and (3), such Confidential Information shall continue to be subject to restrictions on use and disclosure in this Agreement for the term set forth in Section 8.1.2.

-45-

RBNC shall duly execute and deliver, or cause to be duly executed and delivered, such instruments and shall do and cause to be done such activities and things, including the filings of such assignments, agreements, documents and instruments, as may be necessary under, or as AMGEN may reasonably request in connection with, AMGEN’s rights under this Section 9.5 (Effects of Termination for Licensed Compounds, Program Compounds and Products that are not RBNC Compounds).

Section 9.6 Effects of Termination for RBNC Compounds. Upon termination by either Party under Section 9.2 (Termination by AMGEN), Section 9.3 (Termination by RBNC) or Section 9.4 (Termination Upon Bankruptcy), with respect to any Products containing RBNC Compounds:

(a) All rights and licenses granted by AMGEN to RBNC in Article 2 (License Grant) will terminate, and RBNC and its Affiliates, and (subject to Section 9.6(b)) Sublicensees will cease all use of Licensed Know-How and Licensed Patents.

(b) Such termination of this Agreement will automatically terminate any sublicense granted by RBNC pursuant to Section 2.2 (Sublicenses) unless AMGEN has approved such sublicense in writing, in which case all rights under such sublicense shall be deemed to survive termination as long as Sublicensee complies with its obligations thereunder, and provided further that in no event will AMGEN be obligated to fulfill any of RBNC’s obligations under such sublicense that extend beyond the obligations of AMGEN set forth in this Agreement.

(c) As between the Parties, RBNC will retain rights to the RBNC Compounds and to any Products that contain RBNC Compounds; provided, the Exploitation of such Products does not require the use or practice of any Licensed Know-How or any intellectual property rights of AMGEN.

(d) Each Party shall, at Disclosing Party’s written request and election, either (i) destroy all copies of Disclosing Party’s Confidential Information relating to such RBNC Compounds in the possession or control of Receiving Party and confirm such destruction in writing to Disclosing Party, or (ii) return to Disclosing Party, at Disclosing Party’s expense, all copies of Disclosing Party’s Confidential Information relating to such RBNC Compounds in the possession or control of Receiving Party. Notwithstanding the foregoing, Receiving Party shall be permitted to retain (1) such Confidential Information to the extent necessary for purposes of performing any continuing obligations or exercising any ongoing rights under this Agreement, (2) a single copy of such Confidential Information for archival purposes, and (3) such Confidential Information that is contained in any computer records or files that have been created solely by Receiving Party’s

AMGEN shall duly execute and deliver, or cause to be duly executed and delivered, such instruments and shall do and cause to be done such activities and things, including the filings of such assignments, agreements, documents and instruments, as may be necessary under, or as RBNC may reasonably request in connection with, RBNC’s rights under this Section 9.6 (Effects of Termination for RBNC Compounds).
