Notwithstanding the foregoing. GSK may use Third Party contractors for distribution operations and logistics for Ivory without Amgen’s prior written consent (but with prior notice to and consultation with Amgen), provided that such Third Party contractor is not a pharmaceutical or biotechnology company or an affiliate thereof.

For each co-promotion year, the ECC will establish a planned number of Details by GSK for Ivory in the applicable [*], consistent with the Expansion Brand Plan. Amgen will exercise the Option by delivering [*] prior written notice and such notice will indicate the percentage of Planned Details Amgen desires to conduct in the applicable [*] (the “Opt-In Notice”). In addition, beginning on the Opt-In Date, at Amgen’s request, Amgen and GSK will cooperate to increase Amgen’s commercial operational responsibility for activities related to Ivory in such [*]. Promptly after delivery of the Opt-In Notice, the ECC will meet to discuss amending the then-current Expansion Brand Plan for the applicable [*] to include (a) the specific Detailing responsibilities of Amgen, and (b) alignment between the Parties in the conduct of their commercial activities in such [*]. The ECC will also agree on a baseline sales forecast for Ivory in the [*] (the “Baseline”), which will be based upon the expected sales forecast for the Option Exercise Year (which, if not a calendar year, will be a twelve (12) month period comprising a portion of each of two calendar years) in the then-current Expansion Brand Plan; provided, that if the Party’s respective members of the ECC cannot mutually agree that the then-current Expansion Brand Plan forecast or an alternative forecast is an appropriate Baseline, then the Baseline will be an amount equal to [*].

The allocation of operational responsibility for commercialization activities hereunder as well as the conduct of such activities by the Parties will be subject to comprehensive discussion by the

ECC and ESC, as applicable, where each Party will consider the input of the other with respect to the conduct of such activities. The commercial activities will be allocated between the Parties taking into consideration all relevant factors, including the capabilities of each Party to deliver the highest quality product in the most cost-effective manner, without duplication of efforts between the Parties. Amgen may terminate or reduce its co-promotion activities under this Section 12.8.1 (Option) in any [*] on no less than [*] prior written notice, unless otherwise agreed by the Parties; provided, that if Amgen opts to terminate or reduce its co-promotion activities in a [*], it will not have the right to resume or increase such activities in such [*] thereafter, without GSK’s prior consent.

If GSK performs less Details in the applicable [*] in a year than the Planned Details for such year (such number of Details not performed, the “Reduction Amount”), then GSK will reimburse Amgen in full for costs incurred by Amgen in connection with Amgen’s Detailing in such [*] for such year, at rates equal to [*], to the extent the Reduction Amount of Details are performed by Amgen. For (i) all Amgen Details of Ivory in the [*] in a particular year in excess of the Reduction Amount, if applicable to such year, and (ii) all Amgen Details of Ivory in the [*] in a particular year if GSK performs all the Planned Details in the applicable [*] in such year, then in each such case GSK will reimburse Amgen for costs incurred by Amgen in connection with such Detailing at rates equal to [*], but only to the extent that [*]. The Parties will discuss a process to calculate and pay any such available reimbursement on a quarterly basis.

Amgen will provide to GSK any such training materials that the Parties mutually agree will be provided, at Amgen’s expense. GSK will use the training materials provided by Amgen to train GSK’s sales representatives with respect to the marketing and sale of Ivory in the Expansion Scope; provided that, if GSK deems it necessary, GSK may develop additional training materials for the marketing and sale of Ivory in the Expansion Scope. Any such new training materials will be subject to prior review and approval of Amgen, such approval not to be unreasonably withheld. GSK will be

solely responsible for the training of its sales representatives in the Expansion Scope and for providing refreshment of such training from time to time as appropriate, and will conduct such training in accordance with Applicable Law and applicable national and international pharmaceutical industry codes of practices. Amgen will own all right, title and interest in the training materials developed hereunder (except with respect to GSK Housemarks contained therein).

Information Concerning Ivory.

Public Statements. GSK will ensure that no claims or representations in respect of Ivory or the characteristics thereof are made by or on behalf of it or its Affiliates (by sales force members or otherwise) that have not been approved by Amgen or which do not represent an accurate summary or explanation of the labeling of Ivory.

Ownership. GSK will not represent to any Third Party that it has any proprietary or property right or interest in Ivory (or the Product Trademarks or any Patents claiming or covering Ivory or its manufacture, use or sale), except for the rights expressly granted to GSK hereunder. Furthermore, GSK acknowledges that it does not have any right, title or interest in Ivory or the Product Trademarks.

Promotional Materials.

Development. In addition to any Promotional Materials agreed to be provided in the approved Launch Plan for a country, the ECC will discuss what promotional materials related to the promotion and sale of Ivory outside the Expansion Scope would be useful for GSK to use with respect to the promotion and sale of Ivory in the Expansion Scope. Amgen will provide to GSK copies of the Brand Book, standard language document and any marketing messaging templates and samples of promotional, scientific exchange and disease state materials that the Parties mutually agree will be provided, at Amgen’s expense. GSK will be responsible for any further development of Promotional Materials, including the costs thereof. If GSK proposes to develop Promotional Materials that are inconsistent with the written content or messaging of the materials provided by Amgen in accordance with this Section 4.14.1 (Development), GSK will provide to Amgen for approval copies of any such proposed inconsistent Promotional Materials and GSK will specify all aspects that are inconsistent with the materials provided by Amgen. Amgen will respond to any such requests for approval within [*] (commencing as of receipt of an English translation, if requested or provided). If Promotional Materials are not in English, GSK will also provide Amgen with an English translation if one has been or will be prepared for GSK’s own purposes (and if not, GSK will provide one upon request of Amgen, at Amgen’s expense). If Amgen ceases to use any particular promotional material outside the Expansion Scope because it believes such material may no longer be accurate or appropriate for use, GSK will cease use of any such corresponding Promotional Material for the Expansion Scope (or the Parties will agree upon appropriate modifications to the Promotional Material) upon notice from Amgen.

Ownership. Amgen will own all right, title and interest in and to any and all Promotional Materials directed to Ivory including applicable Copyrights and Product Trademarks (except with respect to any GSK Housemark included in any Promotional Materials), and GSK will execute all documents and take all actions as are reasonably requested by Amgen to vest such title in Amgen. GSK will provide to Amgen a copy of all Promotional Materials; provided, that GSK will not be required to provide such Promotional Materials in advance of their use if they are consistent with the materials provided by Amgen to GSK under Section 4.14.1 (Development).

Medical Inquiries and Product Inquiries. Amgen will provide GSK with responses for medical questions or inquiries from members of the medical and paramedical professions and consumers regarding Ivory. GSK will respond to inquiries addressed by the responses provided by Amgen only in accordance with such responses. Amgen will provide to GSK contact details to allow GSK to obtain information to address questions for which GSK and its sales representatives have not received prepared answers or which are not answered by then existing Ivory information provided by Amgen (including with respect to technical information such as identification, ingredients or stability/storage) (collectively “Unaddressed Inquiries”). GSK will respond to any Unaddressed Inquiries only in accordance with the information provided by Amgen.

Supply. GSK will obtain supply of Ivory exclusively from Amgen or its designee and in accordance with the Supply Agreement. GSK will take reasonable steps (including as may be reasonably requested by Amgen) to ensure Ivory sold by it is not used outside the Expansion Territory. GSK will pay to Amgen the pricing set forth in the Supply Pricing Schedule for the supply of Ivory under the Supply Agreement. If GSK believes that the supply price set forth in the Supply Pricing Schedule would make commercialization of Ivory in a particular country in the Expansion Scope not commercially viable, considering the relevant commercial situation in such country, including anticipated pricing and reimbursement of Ivory, competitive landscape, product penetration, long term sales growth and other relevant factors, GSK may request that the ESC consider an adjustment to the supply price for such country that would make commercialization of Ivory in such country commercially viable. Upon such request, the ESC will consider in good faith whether such an adjustment is appropriate for such country and for how long, and GSK will provide to the ESC all reasonably requested information for it to evaluate the requested adjustment. Any actual adjustment to the supply price for a country will require mutual written agreement of the Parties.

Other Agreements. Promptly following the Effective Date, GSK and Amgen (or Affiliates of such entities) will complete the negotiation of, and enter into, the Supply Agreement, Quality Agreement and Safety Agreement.

DEVELOPMENT, REGULATORY AND SAFETY

Development Activities. All development activities within the Expansion Territory conducted for the purpose of the collaboration hereunder will be performed in accordance with this Agreement, the applicable Development Plan and Development Budget, including Phase IV Studies, generation of health economics information, and approval of requests to perform ISS. For the avoidance of doubt, Amgen will have the right to conduct research and development activities for Ivory in the Expansion Territory for purposes other than the collaboration hereunder, and to conduct all regulatory activities related thereto.

Updates. The Development Plans and Development Budgets established by the EDC in accordance with Section 3.5 (Establishment of Plans) will be reviewed and updated by the EDC on an annual basis; provided, that if GSK believes development activities in addition to those contained in the applicable Development Plan are required or advisable with respect to the commercialization of Ivory in any country within the Expansion Territory, it will have the right to propose such activities (together with a reasonably detailed description thereof) to the EDC at any time. The EDC will meet to discuss such proposal, and GSK will provide to the EDC any information reasonably requested to facilitate evaluation of the proposal. The EDC may determine that: (i) Amgen will conduct such proposed development activity; (ii) GSK will conduct such proposed development activity; or (iii) the development activity will not be conducted.

Conduct of Development. The Parties will reasonably cooperate in the conduct of the activities set forth in the applicable Development Plan, including the preparation of protocols and the development of documents therefor in accordance with Section 5.1.4 (Development Documents). GSK will not knowingly provide or sell Ivory to Third Parties to conduct development activities unless set forth in the Development Plan.

Development Data. Each Party will solely own all data generated in its development activities conducted hereunder for the Expansion Scope, and such data will be subject to the license from GSK to Amgen under Section 8.5 (License Grant by GSK) or from Amgen to GSK under Section 8.4 (License Grant by Amgen), as applicable. GSK will not use any such data that is specific to Ivory, whether licensed or owned, for any purpose except with respect to Ivory in the exercise of its rights and performance of its obligations hereunder.

Development Documents.

Development. In addition to any development documents agreed to be provided in the approved Launch Plan for a country, the EDC will discuss what development documents related to the development of Ivory outside the Expansion Scope would be useful for GSK to use with respect to the development of Ivory in the Expansion Scope. Amgen will provide to GSK any such

development documents that the Parties mutually agree will be provided, at Amgen’s expense. The Parties will reasonably cooperate in the development of relevant documents for the development of Ivory in the Expansion Scope as required by the applicable Development Plan; provided, that GSK will be responsible for the production of development documents to be used by it in the Expansion Scope, including the costs thereof. If GSK proposes development documents that are inconsistent with the written content or messaging of the materials provided by Amgen in accordance with this Section 5.1.4.1 (Development), GSK will provide to Amgen for approval copies of any such proposed inconsistent development documents and GSK will specify all aspects that are inconsistent with the materials provided by Amgen. Amgen will respond to any such requests for approval within [*] (commencing as of receipt of an English translation, if requested or provided). If any such development documents are not in English, GSK will also provide Amgen with an English translation if one has been or will be prepared for GSK’s own purposes (and if not, GSK will provide one upon request of Amgen, at Amgen’s expense). If Amgen ceases to use any development documents outside the Expansion Scope because it believes such materials may no longer be accurate or appropriate for use, GSK will cease use of any such corresponding development documents for the Expansion Scope (or the Parties will agree upon appropriate modifications to the development documents) upon notice from Amgen.

Ownership. Amgen will own all right, title and interest in and to any and all development documents directed to Ivory including applicable Copyrights and Product Trademarks (except with respect to any GSK Housemark included in any development documents), and GSK will execute all documents and take all actions as are reasonably requested by Amgen to vest such title in Amgen. GSK will provide to Amgen a copy of all development documents used in the Expansion Scope; provided, that GSK will not be required to provide such development documents in advance of their use if they are consistent with the materials provided by Amgen to GSK under Section 5.1.4.1 (Development).

Development Costs. GSK will reimburse Amgen for costs (including FTE costs) actually incurred by Amgen in connection with its conduct under the Development Plans in accordance with the applicable Development Budget. Such costs will be reimbursed on a calendar quarterly basis, within sixty (60) days of receipt of an invoice and supporting documentation therefor. Amgen will provide prompt, written advance notice to GSK if it becomes aware of any anticipated costs in excess of the applicable Development Budget. Unless otherwise agreed by the Parties in advance, in writing, costs reported by Amgen incurred in excess of [*]

of any aggregate amounts budgeted to be incurred by or on behalf of Amgen for its activities for a calendar quarter in the then-current Development Budget will not be reimbursed by GSK as described above. If Amgen conducts development activities in accordance with a Development Plan, and GSK notifies Amgen in writing that GSK desires to cease such activities, Amgen can elect to continue such activities at its own cost or to cease such activities as soon as reasonably practicable, in accordance with Applicable Law and accepted national and international pharmaceutical industry codes of practices in and for the Expansion Territory, and GSK will pay for all cancellation and wind-down costs associated therewith.

Regulatory Filings.

Preparation of Filings. Unless otherwise set forth in the applicable Launch Plan or Development Plan, GSK will have operational responsibility for the preparation and submission of all Regulatory Filings for Ivory in the Expansion Scope. The EDC will discuss what Regulatory Filings, if any, related to Ivory outside the Expansion Scope would be useful for GSK to use with respect to the registration of Ivory in the Expansion Scope. Amgen will provide to GSK any such Regulatory Filings that the Parties mutually agree will be provided, at Amgen’s expense. GSK will use such Regulatory Filings solely in preparing Regulatory Filings for Ivory in the Expansion Scope.

Amgen Review and Comment. GSK will provide to Amgen a draft copy of any Regulatory Filing in the Expansion Territory (and any Regulatory Filing relating to manufacturing made by GSK in accordance with Section 5.4 (Manufacturing Matters)) and provide no less than [*] (where the Regulatory Filing only contains data that has been previously approved by Amgen or utilized by Amgen in regulatory filings outside the Expansion Territory) and no less than [*] (where the Regulatory Filing re-orders data or omits data or the like from the Regulatory Filing provided by Amgen, in a manner that may reasonably be deemed to alter the material message or content of the data, or where the Regulatory Filing contains data not previously utilized by Amgen in Regulatory Filings outside the Expansion Territory) for Amgen to review prior to filing it with a Governmental Authority. For any such Regulatory Filings that are not in English, GSK will provide an English translation thereof if one has been or will be prepared for GSK’s own purposes (and if not, will provide one upon request of Amgen, at Amgen’s expense). GSK will consult with and make all changes requested by Amgen with respect to Regulatory Filings in the Expansion Territory, to the extent reasonably practicable (subject to the other provisions of this Agreement), and will delete information specified by Amgen where Amgen believes the relevant Governmental Agency may not have adequate provisions to protect the confidentiality of such information. Upon request of Amgen, GSK will promptly provide to Amgen a copy of any Regulatory Filing submitted in the Expansion Territory.

Regulatory Approvals. Unless otherwise set forth in the applicable Launch Plan or Development Plan, GSK will hold in its name (or the name of its Affiliate) all Regulatory Filings for Regulatory Approval and Regulatory Approvals for commercialization of Ivory in the Expansion Scope. For the sake of clarity, Amgen may hold in its own name any Regulatory Filings or Regulatory Approvals with respect to the development or manufacture of Ivory in the Expansion Scope. GSK will provide to Amgen a copy of any Regulatory Approval received from a Governmental Authority in the Expansion Scope promptly after receipt thereof. Where documents (filings or approvals) are not in English, GSK will also provide an English translation thereof if one has been or will be prepared for GSK’s own purposes (and if not, will provide one upon request of Amgen, at Amgen’s expense). Upon the request of either Party, the other Party will provide a right of reference and access to Regulatory Filings (and any Regulatory Filing relating to manufacturing made by GSK in accordance with Section 5.4.2 (Manufacturing Information)) or Regulatory Approvals for Ivory in the Expansion Territory. Amgen will provide such right of reference and access to GSK with respect to Regulatory Filings and Regulatory Approvals for Ivory outside the Expansion Territory, in each case as reasonably necessary for GSK’s commercialization of Ivory in the Expansion Scope.

Prescribing Information, Label and Core Data Sheet. Notwithstanding anything herein to the contrary, GSK will ensure that the Ivory prescribing information, product label and core data sheet in the Expansion Scope are consistent with Amgen’s prescribing information, core data sheet and product label in the applicable country of origin for Ivory provided by Amgen for the Expansion Scope. GSK will not permit any change to such prescribing information, label or core data sheet without Amgen’s prior written consent, and will make any change thereto instructed by Amgen (or request such change, where approval of a Governmental Authority is required by Applicable Law). This Section 5.2 (Regulatory Filings) does not apply to any submission to any Governmental Authority of adverse event reports, periodic safety reports, or other similar safety submissions, which submissions will be governed by the Safety Agreement.

Costs. Except as may expressly be set forth herein to the contrary, GSK will be solely responsible for all costs associated with preparing, translating and submitting Regulatory Filings, and obtaining and maintaining Regulatory Approvals, in the Expansion Scope, including registration fees. Notwithstanding the foregoing, if GSK reasonably requires Amgen to provide information already in Amgen’s possession to enable GSK to prepare Regulatory Filings for the Expansion Scope, then Amgen will be solely responsible for its own costs associated therewith.

Regulatory Communications.

GSK Responsibility. Except as expressly set forth herein (including Section 5.4.3 (Manufacturing Filings) and Section 5.1 (Development Activities)) or as set forth in the Safety Agreement, GSK will have responsibility, at its sole cost, for all correspondence and for any official communication with Governmental Authorities (except as Amgen may be required by Applicable Law or a Governmental Authority to communicate) regarding Ivory in the Expansion Scope. GSK will promptly file any updates or changes to Regulatory Filings and Regulatory Approvals as reasonably directed by Amgen.

Amgen Review and Comment. Except as set forth in the Safety Agreement and without prejudice to the time periods relevant to review of Regulatory Filings pursuant to Section 5.2 (Regulatory Filings), GSK will supply to Amgen a copy of: (i) all material correspondence and communications (including a written description, with respect to any oral communication) with any Governmental Authority with respect to Ivory at least [*] prior to provision of such correspondence or communication to such Governmental Authority (or as promptly as possible where exigent circumstances make such provision impractical); and (ii) all such material correspondence and communications received from any Governmental Authority with respect to Ivory within [*] after receipt of any such correspondence. Materials provided pursuant to Section 5.2 (Regulatory Filings) need not be re-provided pursuant to this Section 5.3 (Regulatory Communications) unless changed. Where correspondence or communications are not in English, GSK will also provide an English translation if one has been or will be prepared for GSK’s own purposes (and if not, will provide one upon request of Amgen, at Amgen’s expense), but will not be required to do so within the [*] period set forth above. To the extent reasonably practicable (subject to the other provisions of this Agreement), GSK will comply with Amgen’s comments concerning any meeting or written or oral communication with any Governmental Authority. Amgen will reasonably cooperate with GSK in responding to any inquiry made by a Governmental Authority in the Expansion Scope.

Regulatory Meetings. Amgen will be entitled to [*] any discussions between GSK and any Governmental Authority relating to Ivory at Amgen’s own expense, and GSK will give Amgen [*] prior written notice thereof (or prompt written notice, if [*] notice is impractical); provided, that the foregoing will not apply to informal meetings or teleconferences that are unscheduled or intended by the Governmental Authority to be between it and GSK representatives only, and in such case, GSK will thereafter provide Amgen prompt written notice of such communication with a summary of the discussion. If GSK communicates with any Governmental Authority in a manner that is inconsistent with the regulatory strategy agreed by the EDC or communications of Amgen outside the Expansion Scope and disclosed to GSK, and such

Manufacturing Matters.

Initial Responsibility. Unless otherwise provided in the applicable Launch Plan or Development Plan, GSK will have operational responsibility for all correspondence and for any official communication with Governmental Authorities regarding manufacturing of Ivory in the Expansion Scope (except as Amgen may be required by Applicable Law or a Governmental Authority to communicate). Amgen will have the option to transfer operational responsibility from GSK to Amgen for some or all correspondence and for specified official communication (except as GSK may be required by Applicable Law or a Governmental Authority to communicate) upon approval of the EDC, in circumstances where Amgen reasonably believes it is advisable to protect its confidential information. If Amgen desires to transfer such operational responsibility from GSK to Amgen, Amgen will first notify the EDC and the EDC will discuss the risks and benefits of such transfer, including potential impact to GSK’s existing relationships with the applicable Governmental Authority with respect to Ivory, potential disruption to Ivory development, registration or commercialization, and coordination with respect to regulatory communications to the applicable Governmental Authority. The EDC will then determine whether to approve such transfer of operational responsibility and, if it does so approve, GSK may escalate such issue to the ERC in accordance with Section 2.13.3 (Decision-Making) if it chooses. With respect to any such correspondence and communication, each Party will promptly provide the other with copies of material written correspondence as reasonably necessary to permit GSK to comply with its relevant regulatory obligations or as reasonably requested by Amgen (provided that Amgen will not be required to disclose proprietary or competitively sensitive information).

Manufacturing Information. Upon GSK’s request, Amgen will reasonably cooperate with GSK to make and provide copies of any direct communications by Amgen either to or from the Governmental Authorities having jurisdiction in the Expansion Territory regarding the manufacture of Ivory by Amgen for supply to GSK; provided, that Amgen’s obligation to provide GSK with manufacturing and process information is limited to the circumstance where the information is reasonably required for GSK to carry out its commercialization responsibilities, or access to such information is required by Applicable Law or a Governmental Authority having jurisdiction in the Expansion Territory. GSK will use such information only to the extent required by such Applicable Law or Governmental Authority or to the extent reasonably required to carry out its commercialization responsibilities hereunder and will only permit access to those of its employees who need

to know for such purposes. Amgen will also have the right to instead provide any such manufacturing information directly to the relevant Governmental Authority (including by provision of a drug master file) if such provision will satisfy such requirement. Notwithstanding anything herein to the contrary, Amgen will not be required to provide to GSK nor to allow GSK to access (except a right of reference as set forth in this Section 5.4.2 (Manufacturing Information) to the extent necessary), including with respect to Regulatory Filings, Amgen’s manufacturing information with respect to Ivory or any sections of any Regulatory Filing related thereto or to provide information relating to any product other than Ivory.

Manufacturing Filings. Unless otherwise set forth in the applicable Launch Plan or Development Plan, GSK will have operational responsibility for the preparation and submission of all Regulatory Filings required to be filed with any Governmental Authority in the Expansion Territory with respect to the manufacture of Ivory provided to GSK by Amgen (including with respect to the use of any contract manufacturer to produce Ivory on Amgen’s behalf) (the foregoing “Manufacturing Filing Responsibilities”). The EDC will have the right to transfer operational responsibility for some or all Manufacturing Filing Responsibilities from GSK to Amgen (except as GSK may be required by Applicable Law or a Governmental Authority to communicate). In the event of any such transfer, the Parties will cooperate to transition the relevant Manufacturing Filing Responsibilities to Amgen and Amgen thereafter will be responsible for the relevant Manufacturing Filing Responsibilities at its sole cost. Each Party will provide the other any cooperation reasonably requested in connection with any such filings.

Health Technology Assessments. The EDC will oversee the generation of all data for HTAs for GSK’s use in Regulatory Filings for Ivory within the Expansion Scope. Upon GSK’s reasonable request, Amgen will provide to GSK HTA data or methodology for generating HTA data so GSK can generate such data as agreed by the EDC. GSK will use such methodology and any such HTA data solely for use in preparing Regulatory Filings necessary to support pricing and reimbursement filings for Ivory in the countries in the Expansion Territory for which the EDC approves such use. GSK will only permit access to any such methodology solely to those of its employees who need to know for the intended purpose. Prior to implementation, GSK will submit to the EDC for discussion a draft of the overall HTA strategy as part of the access and reimbursement plan, which will align with the strategic intent and design of Amgen’s positioning of Ivory and cost effectiveness strategy for Ivory unless otherwise agreed by the EDC. GSK will provide to Amgen for approval copies of any proposed HTAs in the Expansion Territory. Amgen will respond to any such requests for approval within [*] (where such data has been previously approved or utilized by Amgen for HTAs outside the Expansion Territory) and no less than [*] (where such data has not been previously approved or utilized by Amgen for HTAs outside the Expansion Territory) prior to submitting it to a Governmental Authority

Labeling and Packaging Materials. Notwithstanding anything herein to the contrary, GSK will not agree with any Governmental Authority on any product label (i.e., physical sticker), package inserts or packaging with respect to Ivory without the prior written consent of the EDC; provided, that the EDC will not unreasonably withhold consent if the product label, package inserts or packaging is consistent with the regulatory strategy provided in the approved Launch Plan or Development Plan for the applicable country. No product label, package inserts, or packaging for Ivory may be used or distributed by GSK if any of them are inconsistent with the regulatory strategy provided in the approved Launch Plan or Development Plan for the applicable country without the prior approval of the EDC. GSK will not modify or alter any product label, package inserts or packaging for Ivory, without the prior approval of such modification or alteration by the EDC, and will make any changes to any labeling, package inserts or packaging for Ivory directed to be made by the EDC (to the extent permitted by Applicable Law).

Product Technical Complaints; Recalls; Returns.

Product Technical Complaints. Complaints with respect to Ivory in the Expansion Scope will be handled in accordance with the Quality Agreement.

Recalls or Other Corrective Action. If either Party proposes to the EDC to initiate a recall, market withdrawal, field alert or other corrective action with respect to Ivory in the Expansion Territory, the EDC will promptly meet to consider such proposed action and will discuss the implementation of any such corrective actions. The Party requiring such action will bear all costs with respect to the conduct of such action and the other Party will reasonably cooperate therewith. The conduct of any recall, market withdrawal, field alert or other corrective action with respect to Ivory in the Expansion Scope will be handled in accordance with the Quality Agreement.

Returns. If any quantities of Ivory are returned to GSK from GSK’s customers, GSK will destroy such quantities and maintain appropriate, auditable documentation with respect thereto.

PAYMENTS

Support Costs. On a calendar quarterly basis, GSK will reimburse Amgen for all costs actually incurred in such quarter by Amgen or its Affiliates, including internal costs at the FTE Rate, for activities conducted in support of the Expansion Scope and not otherwise included in the price of supply under the Supply Agreement, reimbursed as set forth in Section 5.1.5 (Development Costs), or Section 4.11.2 (Costs). Such costs will include only those costs that are

Payment Method. All payments made hereunder between the Parties will be made in U.S. Dollars, except as otherwise agreed by the Parties. Each Party will pay all sums due hereunder by wire transfer, or electronic funds transfer (EFT) in immediately available funds. If the EFT option is chosen by Amgen or GSK, a completed electronic funds transfer form will be provided in a timeframe that facilitates timely payment. Each Party will promptly notify the other Party of the appropriate account information to facilitate any such payments.

Audits. Each Party will keep complete and accurate records pertaining to the activities to be conducted hereunder in sufficient detail to permit the other Party (the “Auditing Party”) to confirm the accuracy of all payments due hereunder, and such records will be open (in such form as may be available or reasonably requested) to inspection for [*] following the end of the period to which they pertain. The Auditing Party will have the right, at its own expense to have an independent, certified public accountant, selected by it, perform a review the records of the other Party (the “Audited Party”) applicable to amounts payable hereunder (including any records kept in the ordinary course of the Audited Party’s business) upon no less than sixty (60) days’ notice, during regular business hours and under reasonable obligations of confidentiality. The report of such accountant will be made available to both Parties simultaneously, promptly upon its completion. The Auditing Party’s right to perform an audit pertaining to any calendar year will expire [*] after the end of such year and the books and records for any particular calendar year will only be subject to one (1) audit. Should an inspection pursuant to this Section 6.3 (Audits) lead to the discovery of a payment discrepancy, then the appropriate Party will pay to the other the amount of the discrepancy (plus, if the error was in favor of the Audited Party, interest accrued at the Contract Interest Rate, compounded annually from the day the relevant payment(s) were due). If a payment discrepancy was greater than [*] of the correct amount for the audited period and the discrepancy was in favor of the Audited Party, then the Audited Party will pay the reasonable out-of-pocket cost of such inspection. This Section 6.3 (Audits) does not apply to or include manufacturing audits or regulatory inspections.

Withholding. If Applicable Law requires a Party to pay or withhold Taxes with respect to any payment to be made pursuant to this Agreement, the paying Party will notify the other in writing of such payment or withholding requirements prior to making the payment and provide such assistance to the receiving Party, including the provision of such documentation as may be required by a tax authority, as may be reasonably necessary in such Party’s efforts to claim an exemption from or reduction of such Taxes. Each Party will withhold any Taxes required by Applicable Law to be withheld from the amount due, remit such Taxes to the appropriate tax authority, and furnish the other Party with proof of payment of such Taxes promptly following payment thereof. If Taxes are paid to a tax authority, each Party will provide the other such assistance as is reasonably required to obtain a refund of Taxes withheld, or obtain a credit with respect to Taxes paid. In the event that the governing tax authority retroactively determines that a payment made by a Party to the other pursuant to this Agreement should have been subject to withholding (or to additional withholding) for Taxes, and such Party (the “Withholding Party”) remits such withholding Taxes to the tax authority, the Withholding Party will have the right to offset such amount, including any interest and penalties that may be imposed thereon, against future payment obligations of the Withholding Party under this Agreement; provided however, that the Withholding Party may also pursue reimbursement by any other available remedy.

VAT. All payments due a Party pursuant to this Agreement will be paid exclusive of any VAT and other indirect Taxes (which, if applicable, will be payable by the paying Party upon receipt of a valid VAT invoice). If such amounts of VAT are refunded by the applicable Governmental Authority or other fiscal authority subsequent to payment, the Party receiving such refund will transfer such amount to the paying Party within forty-five (45) days of receipt.

Late Payment. Any payments or portions thereof due hereunder which are not paid when due will bear interest at the Contract Interest Rate, compounded annually, calculated on the number of days such payment is delinquent. This Section 6.6 (Late Payment) will in no way limit any other remedies available to either Party.

Change in Accounting Periods. From time to time, either of the Parties may change its accounting and financial reporting practices from calendar quarters and calendar years to fiscal quarters and fiscal years or vice versa. If a Party notifies the other in writing of a change in its accounting and financial reporting practices from calendar quarters and calendar years to fiscal quarters and fiscal years or vice versa, then thereafter, beginning with the period specified in the notice, the Parties will cooperate to determine a way to report and reconcile each Party’s accounting periods so as to facilitate payments to be made hereunder.

INTELLECTUAL PROPERTY

Invention Ownership. Each Party will own all right, title, and interest in and to all Inventions that are made by or on behalf of such Party, solely or independent of the other Party, and all intellectual property rights related thereto. Any Invention that is jointly made will be owned jointly by the Parties (each a “Joint Invention”). Inventorship will be determined according to United States Patent law (without reference to any conflict of law principles).

Copyright Ownership; Certain Confidential Information. Except as set forth below, each Party will own all right, title, and interest in and to all Copyrights created pursuant to this Agreement that are authored by or on behalf of such Party, solely or independent of the other Party, and all intellectual property rights related thereto; provided, that any Copyrights pertaining to Ivory (including any clinical trial protocols, investigator brochures and informed consent forms, and the product labeling, package inserts, core data sheet and all marketing and Promotional Materials and the Brand Book) will be owned solely by Amgen. The Parties will jointly own all right, title, and interest in and to all Copyrights that are authored by or on the behalf of the Parties jointly; provided, that any Copyrights pertaining to Ivory will be owned solely by Amgen whether created jointly by the Parties or by either Party independent of the other Party. In addition, all Confidential Information to the extent pertaining to Ivory will be the Confidential Information of Amgen (and not of GSK), regardless of which Party created such information (and will not be subject to the exclusion under Section 9.1.1 or 9.1.4). Any Copyrights created by GSK or its Affiliates and specified in this Section 8.2 (Copyright Ownership; Certain Confidential Information) as being owned by Amgen will be considered a work for hire. To the extent any such Copyright is not considered a work for hire, GSK and/or such Affiliate will assign and does hereby assign to Amgen all of its right, title and interest in and to such Copyright and intellectual property rights therein and thereto. Each Party will duly execute, acknowledge, and deliver to the other all such further papers, including assignments and applications for copyright registration or renewal, as may be reasonably requested and/or necessary to enable such other Party to publish or protect said Copyrights in any and all countries and to vest title to said Copyrights in such other Party (or its nominees, or its or their successor or assigns) in accordance with this Section 8.2 (Copyright Ownership; Certain Confidential Information), and will render such reasonable assistance, at such other Party’s expense, as such other Party may reasonably require in any proceeding or litigation involving said Copyrights.

Joint Ownership. Except as expressly provided in this Agreement, it is understood that neither Party will have any obligation to obtain any approval or consent of, nor pay a share of the proceeds to or account to, the other Party to practice, enforce, license, assign or otherwise exploit Inventions or intellectual property (including Copyrights) owned jointly by the Parties hereunder, and each Party hereby waives any right it may have under the Applicable Law of any jurisdiction to require such approval, consent or accounting. Each Party agrees to

License Grant by Amgen. Amgen hereby grants and causes its Affiliates to grant to GSK and its Affiliates during the Term an [*] license to Ivory Intellectual Property solely to the extent necessary to develop, use, sell, offer for sale and import Ivory in the Expansion Scope, and otherwise exercise and perform GSK’s rights and obligations under the terms of this Agreement; subject to Amgen’s retained rights to develop, use and import Ivory in the Expansion Scope for the benefit of countries outside the Expansion Territory and to exercise and perform its rights and obligations under the terms of this Agreement.

License Grant by GSK. GSK hereby grants and causes its Affiliates to grant to Amgen and its Affiliates a [*] license under all Know-How and Patents owned or controlled as of the Effective Date or during the Term (including GSK Inventions) by GSK or its Affiliates solely to develop, use, make, have made, sell, offer for sale and import of Ivory [*], and for performing Amgen’s rights and obligations hereunder. Such license is sublicensable by Amgen or its Affiliates solely to Third Parties to whom Amgen or its Affiliates also grant a license to Know-How or Patents owned or controlled by Amgen or its Affiliates claiming Ivory, its formulation or the use thereof; provided, that such sublicense will terminate no later than the date on which the license to the Third Party to Amgen Know-How or Patents described above terminates.

Prosecution and Maintenance.

Primary Prosecution. Amgen will control, by itself or through outside counsel reasonably acceptable to GSK and directed by Amgen, and have final decision making authority (after consultation between the Patent Coordinators in accordance with the terms and conditions of this Agreement) and [*] with respect to the Prosecution and Maintenance of Patents and Product Trademarks within Ivory Intellectual Property, in each case solely in the Reserved Territory and Expansion Territory (collectively, the “Expansion IP”), and with respect to the preparation and filing for any patent term extensions or similar protections therefor. Through the Patent Coordinators: (i) Amgen will provide GSK with copies of and an opportunity to review and comment upon the text of the applications relating to the Expansion IP at least [*] before filing; provided, that if it is not reasonably practicable to provide such application in such [*] period, then Amgen will provide either a draft copy of such application or a statement of intent to file such application in such [*] period; (ii) Amgen will provide GSK with a copy of each submission made to and document received from a patent authority, court or other tribunal regarding any Expansion IP reasonably promptly after making such filing or receiving such document, including a copy of each application for each Product Trademark and Patent within the Expansion IP as filed together with notice of its filing date and application number; (iii) Amgen will keep

GSK advised of the status of all material communications, actual and prospective filings or submissions regarding the Expansion IP, and will give GSK copies of and an opportunity to review and comment on any such material communications, filings and submissions proposed to be sent to any patent authority or judicial body; and (iv) Amgen will consider in good faith GSK’s comments on the communications, filings and submissions for the Expansion IP. With respect to any filings or other materials provided to GSK under this Section 8.6 (Prosecution and Maintenance), Amgen will have the right to redact any manufacturing information and any information relating to any product other than Ivory from any such filings and materials.

Secondary Prosecution. If Amgen proposes to abandon or fail to maintain any Patent, Product Trademark or application within the Expansion IP, or if Amgen proposes to offer GSK the right to control Prosecution and Maintenance of any Patent, Product Trademark or application within the Expansion IP, Amgen will give GSK reasonable notice thereof (with sufficient time for GSK to assume control thereof and continue the Prosecution and Maintenance of such Patent, trademark or application) and thereafter GSK may, upon prompt written notice to Amgen (delivered in no event later than [*] after receipt of Amgen’s notice), control Prosecution and Maintenance and defense with respect to such Patent or trademark within the Expansion IP thereafter in accordance with this Section 8.6.2 (Secondary Prosecution) (any Patent, trademark or application so assumed, an “Assumed Item”). In such case, GSK will control, by itself or through outside counsel reasonably acceptable to the Parties and directed by GSK, and have final decision making authority (after consultation between the Patent Coordinators in accordance with the terms and conditions of this Agreement) with respect to the Prosecution and Maintenance of Assumed Items in the Expansion Territory, [*], and with respect to the preparation and filing for any patent term extensions or similar protections therefor. Through the Patent Coordinators, GSK will (i) provide Amgen with copies of and an opportunity to review and comment upon the text of the applications relating to the Assumed Items at least [*] before filing; provided, that if it is not reasonably practicable to provide such application in such [*] period, then GSK will provide either a draft copy of such application or a statement of intent to file such application in such [*] period; (ii) provide Amgen with a copy of each submission made to and document received from a patent authority regarding any Assumed Items reasonably promptly after making such filing or receiving such document, including a copy of each application for each item within the Assumed Items as filed together with notice of its filing date and application number; (iii) keep Amgen advised of the status of all material communications, actual and prospective filings or submissions regarding the Assumed Items, and will give Amgen copies of and an opportunity to review and comment on any such material communications, filings and submissions proposed to be sent to any patent

or trademark authority or judicial body; and (iv) reasonably consider in good faith Amgen’s comments on the communications, filings and submissions for the Assumed Items. Notwithstanding the foregoing, GSK will not Prosecute and Maintain any Assumed Item, and will not do so in any manner, that Amgen believes would be reasonably likely to have a material adverse effect on Ivory or intellectual property related to Ivory, and Amgen will have control and final decision-making authority over any such matter; provided, that if Amgen makes a final decision in accordance with this sentence, then Amgen will reimburse GSK for costs incurred in connection with GSK’s implementation of such decision; and provided, further that GSK is not obligated to take action pursuant to such Amgen decision, but if GSK elects not to take a required action then at Amgen’s request GSK will reasonably cooperate to take such action (including, if necessary, transitioning the requisite rights for such purpose) as reasonably necessary to enable Amgen to take the required action. If GSK proposes to abandon or fails to maintain any Assumed Item, or if GSK proposes to offer Amgen the right to control Prosecution and Maintenance of any Assumed Item, GSK will give Amgen reasonable notice thereof (with sufficient time for Amgen to assume control thereof and continue the Prosecution and Maintenance of such Assumed Item) and thereafter Amgen may, upon prompt written notice to GSK (delivered in no event later than [*] after receipt of GSK’s notice) and at Amgen’s sole cost, control Prosecution and Maintenance and defense with respect to such Assumed Item thereafter in accordance with Section 8.6.1 (Primary Prosecution).

Defense and Settlement of Third Party Claims. If a Third Party asserts that Patents, Know-How or other rights owned or controlled by it are infringed by the activities hereunder of either of the Parties (an “Infringement Claim”), then defense of such Infringement Claim or the conduct of such proceedings will be managed in accordance with the provisions of Section 11.5 (Defense of Third Party Claims), with coordination and cooperation between the Defending Party and Assisting Party occurring via the Patent Coordinators. If either Party seeks to initiate a nullification or revocation proceeding against any such Patents, Know-How or other rights in response to prospective or actual Third Party Claims of Infringement, the Parties will coordinate and cooperate in regard to such proceedings in accordance with the procedures set forth in Section 11.5 (Defense of Third Party Claims), with coordination and cooperation between the Defending Party and Assisting Party occurring via the Patent Coordinators.

Enforcement. Except as expressly set forth in this Section 8.8 (Enforcement), each Party will retain all its rights to control the enforcement of its own intellectual property.

Amgen Sole Enforcement. Amgen will have the sole right, but not the obligation, to bring an action to enforce the Ivory Intellectual Property against any actual, alleged or threatened infringement or misappropriation by Third Parties (an “Enforcement Action”) in the Reserved Territory, at

Amgen’s sole cost. In the event Amgen elects to bring and prosecute such Enforcement Action, GSK will reasonably assist Amgen and cooperate in any such Enforcement Action at Amgen’s request (and Amgen will reimburse all reasonable, documented, out-of-pocket expenses incurred by GSK in connection therewith), and Amgen will seek and reasonably consider GSK’s comments before determining the strategy via the Patent Coordinators. Without limiting the foregoing, Amgen will keep GSK advised of all material communications, actual and prospective filings or submissions regarding such action, and will provide GSK copies of and an opportunity to review and comment on any such material communications, filings and submissions (provided that Amgen will have the right to redact any Amgen manufacturing information and any information relating to any product other than Ivory from any such materials).

Amgen Primary Enforcement. Amgen will have the first right, but not the obligation, to bring an Enforcement Action in the Expansion Territory, at Amgen’s sole cost. In the event Amgen elects to bring and prosecute such Enforcement Action, GSK will reasonably assist Amgen and cooperate in any such Enforcement Action at Amgen’s request (and Amgen will reimburse all reasonable, documented, out-of-pocket expenses incurred by GSK in connection therewith), and Amgen will seek and reasonably consider GSK’s comments before determining the strategy via the Patent Coordinators. Without limiting the foregoing, Amgen will keep GSK advised of all material communications, actual and prospective filings or submissions regarding such action, and will provide GSK copies of and an opportunity to review and comment on any such material communications, filings and submissions (provided that Amgen will have the right to redact any Amgen manufacturing information and any information relating to any product other than Ivory from any such materials). Amgen will not settle, or consent to any judgment in, any action under this Section 8.8.2 (Amgen Primary Enforcement), without GSK’s prior written consent, not to be unreasonably withheld or delayed.

GSK Secondary Enforcement. In the event Amgen does not commence an Enforcement Action in accordance with Section 8.8.2 (Amgen Primary Enforcement), or otherwise take action to abate any alleged material infringement or misappropriation of any Ivory Intellectual Property within [*] after GSK requests Amgen to do so in writing (or, if later, within [*] after such action can viably be brought by Applicable Law (as, for example, in the case of expiration of a clinical trial exemption to patent infringement)), GSK will be entitled to bring and prosecute such Enforcement Action in the Expansion Territory at GSK’s sole cost and Amgen will cooperate with GSK at GSK’s request (and GSK will reimburse all reasonable, documented, out-of-pocket expenses incurred by Amgen in connection therewith). If GSK elects to bring and prosecute such Enforcement Action, then GSK will seek and reasonably consider Amgen’s comments before determining the strategy via the Patent Coordinators. Without limiting the foregoing, GSK will keep Amgen

advised of all material communications, actual and prospective filings or submissions regarding such Enforcement Action, and will provide Amgen copies of and an opportunity to review and comment on any such material communications, filings and submissions. Notwithstanding the foregoing, GSK will not commence or maintain an Enforcement Action or settlement under this Section 8.8.3 (GSK Secondary Enforcement), and will not conduct any such enforcement or settlement in a manner, that Amgen believes would be reasonably likely to have a material adverse effect on Ivory Intellectual Property or intellectual property related to Ivory; and Amgen will have control and final decision-making authority over any such matter; provided, that if Amgen makes a final decision in accordance with this sentence, then Amgen will reimburse GSK for costs incurred in connection with GSK’s implementation of such decision; and provided, further that GSK is not obligated to take action pursuant to such Amgen decision, but if GSK elects not to take a required action then at Amgen’s request GSK will reasonably cooperate to take such action (including, if necessary, transitioning the requisite rights for such purpose) as reasonably necessary to enable Amgen to take the required action.

Recoveries. All Recoveries obtained under an action brought by Amgen under Section 8.8.1 (Amgen Sole Enforcement) or Section 8.8.2 (Amgen Primary Enforcement) will be retained solely by Amgen. All Recoveries obtained under an action brought by GSK under Section 8.8.3 (GSK Secondary Enforcement) will be retained solely by GSK.

Joining an Action. For any enforcement action under Section 8.8.1 (Amgen Sole Enforcement), 8.8.2 (Amgen Primary Enforcement) or 8.8.3 (GSK Secondary Enforcement), if the non-enforcing Party is an indispensable party to such action or reasonably necessary to be joined in such action to enable enforcement, it will cooperate to join such action at the enforcing Party’s request (and the requesting Party will reimburse all reasonable, documented, out-of-pocket expenses incurred by the joining Party in connection therewith), but the enforcing Party will continue to control the action pursuant to Section 8.8.1 (Amgen Sole Enforcement), 8.8.2 (Amgen Primary Enforcement) or 8.8.3 (GSK Secondary Enforcement), as applicable.

Patent Term Extensions. GSK will provide reasonable assistance to Amgen in connection with obtaining supplemental protection certificates for Patents within the Ivory Intellectual Property or otherwise licensed or assigned hereunder as determined by the Patent Coordinators. To the extent reasonably and legally required to obtain any such supplemental protection certificates in a particular country, GSK will make available to Amgen copies of all necessary documentation to enable Amgen to use the same for the purpose of obtaining the supplemental protection certificates in such country.

Employee Agreements. Prior to beginning work relating to any aspect of the subject matter of this Agreement and/or being given access to Ivory Intellectual Property or Confidential Information of the other Party, each employee, consultant

Trademarks.

Title. Amgen will own all right, title and interest in and to the Product Trademarks, and GSK agrees to assign and hereby assigns to Amgen all right title and interest that GSK has or may acquire in connection with the Product Trademarks. All goodwill arising out of the use of the Product Trademarks or otherwise related to Ivory will inure to the benefit of Amgen. GSK will not, and will ensure that its Affiliates do not: (i) challenge any Product Trademark or the registration thereof in any country; (ii) file, register or maintain any registrations for the Product Trademarks, or for any trademarks or trade names that are confusingly similar to any Product Trademark, in any country without the express prior written consent of Amgen, and such permitted registrations (if any) will be filed, registered or maintained by GSK in Amgen’s name; or (iii) authorize or assist any Third Party to do the foregoing.

Required Use and Compliance.

Except as may be otherwise requested by Amgen, Promotional Materials for Ivory in the Expansion Scope will display only the GSK Housemarks to the extent allowed by Applicable Law. To the extent requested by Amgen and permitted by Applicable Law, GSK will include a specified Amgen Housemark on Promotional Materials. If requested by Amgen prior to submission of an application for Regulatory Approval to market Ivory in a country in the Expansion Scope, GSK will promote Ivory in each indication in such country within the Expansion Scope only under the same Product Trademark utilized by Amgen for such indication outside the Expansion Territory, unless otherwise agreed by the Parties. If promotion under such Product Trademark is not permitted by Applicable Law in a particular country within the Expansion Territory, then the Parties will agree on an alternate trademark for use therein.

GSK agrees that it and its Affiliates will: (i) ensure that each use of the Product Trademarks and/or the Amgen Housemarks by GSK is accompanied by an acknowledgement that the Product Trademarks and Amgen Housemarks are owned by Amgen; (ii) not use the Product Trademarks or Amgen Housemarks in a way that might materially prejudice their distinctiveness or validity or the goodwill of Amgen therein; and (iii) not use any trademarks or trade names so resembling any of the Product Trademarks or Amgen Housemarks as to be likely to cause confusion or deception.

Trademark Licenses.

To GSK. Amgen hereby grants to GSK a [*] license to use the Product Trademarks and Amgen Housemarks as set forth in the Promotional Materials and other materials provided to it by Amgen, solely to market and promote Ivory in the Expansion Scope in accordance with the Expansion Brand Plan, applicable Launch Plan and this Agreement during the period that GSK has rights to promote Ivory hereunder. GSK’s right to use the Product Trademarks and the Amgen Housemarks will terminate, on a country-by-country basis, when GSK’s rights to promote Ivory in such country are terminated or expire hereunder. GSK will take all such steps as Amgen may reasonably request to give effect to the termination of the license to the Product Trademarks and Amgen Housemarks in such country and to record any documents that may be required to evidence the termination of such license.

To Amgen. If Amgen exercises its Option pursuant to Section 4.11.1 (Option), then GSK hereby grants to Amgen a [*] license to use the GSK Housemarks as set forth in the Promotional Materials solely to Detail Ivory in the Expansion Scope in accordance with the Expansion Brand Plan and this Agreement. Amgen’s right to use the GSK Housemarks will terminate, on a country-by-country basis, when GSK’s rights to promote Ivory in such country are terminated or expire; provided, that the license set forth in this Section 8.11.3.2 (To Amgen) will continue for a period of [*] to permit Amgen to use and distribute its inventory of Promotional Materials containing GSK Housemarks returned to Amgen in accordance with Section 12.9.5 (Return of Materials) in such country (or, where the on-hand inventory as of such termination or expiration of such Promotional Materials cannot practically be used within such [*] period, such longer period as reasonably necessary to exhaust such Promotional Materials, but in no event longer than [*]), in connection with Amgen’s Detailing of Ivory. Amgen will take all such steps as GSK may reasonably request to give effect to the termination of the license to the Collaboration Housemarks in the applicable country and to record any documents that may be required to evidence the termination of such license.

Respect of Trademarks. GSK will not have, assert or acquire any right, title or interest in or to any of Product Trademarks or Amgen Housemarks or the goodwill pertaining thereto, and Amgen will not have, assert or acquire any right, title or interest in or to the GSK Housemarks or the goodwill pertaining thereto, in each case by means of entering into or performing under this Agreement, except in each case for the limited licenses explicitly provided in this Agreement.

Infringement. Amgen will monitor the Product Trademarks for infringing uses within the Expansion Scope consistent with its monitoring of product

Community Of Interest. From time to time it may be desirable or beneficial to the Parties to share between each other and their respective outside counsel privileged and/or work product information with respect to certain Patents and/or Know-How related to Ivory, and legal matters relating thereto, and that they share a common interest in the prosecution, defense and enforcement of such Patents and Know-How, including such Patents and Know-How owned or controlled by Third Parties. Therefore, the Parties agree to execute the Joint Community Of Interest Privilege Agreement (attached hereto as the Privilege Agreement Schedule) concurrently with this Agreement.

CONFIDENTIALITY, PUBLICATIONS AND PRESS RELEASES

Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the Term and for [*] thereafter, the receiving Party will keep confidential and will not publish or otherwise disclose or use for any purpose any and all information or materials related to the activities contemplated hereunder and furnished to it by the other Party pursuant to this Agreement (or in the case of GSK, that is created by or on the behalf of GSK and owned by Amgen pursuant to Section 8.2 (Copyright Ownership; Certain Confidential Information) or Section 5.1.3 (Development Data)) that is identified by the disclosing Party as confidential, proprietary or the like or that the receiving Party has reason to believe is confidential based upon its own similar information (collectively, “Confidential Information”). For clarity, GSK will have no right to and will not utilize any Confidential Information of Amgen for activities outside the Expansion Scope or for activities related to products other than Ivory. Notwithstanding the foregoing, Confidential Information will not include any information to the extent that it can be established by written documentation by the receiving Party that such information:

was obtained or was already known by the receiving Party or its Affiliates without obligation of confidentiality as a result of disclosure from a Third Party that the receiving Party did not know was under an obligation of confidentiality to the disclosing Party with respect to such information;

was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party through no act or omission of the receiving Party or its Affiliates in breach of this Agreement;

became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party or its Affiliates in breach of this Agreement; or

was independently discovered or developed by the receiving Party or its Affiliates (without reference to or use of Confidential Information of the disclosing Party).

Authorized Disclosure. Except as expressly provided otherwise in this Agreement, each Party may use and disclose Confidential Information of the other Party solely as follows: (i) as reasonably necessary in conducting the activities contemplated under this Agreement; (ii) with respect to Confidential Information generated in the course of the activities conducted hereunder, to the extent pertaining specifically to Ivory, for use by Amgen in connection with Ivory outside the Expansion Scope or disclosure by Amgen to a partner, GSK or licensee for use with respect to Ivory outside the Expansion Scope; (iii) to the extent such disclosure is to a Governmental Authority as reasonably necessary in filing or prosecuting Patent, Copyright and trademark applications in accordance with this Agreement, prosecuting or defending litigation in accordance with this Agreement, complying with applicable governmental regulations with respect to performance under this Agreement, filing Regulatory Filings, obtaining Regulatory Approval or fulfilling post-approval regulatory obligations for Ivory, or otherwise required by Applicable Law, provided, however, that if a Party is required by Applicable Law to make any such disclosure of the other Party’s Confidential Information it will, except where impracticable for necessary disclosures (for example, in the event of medical emergency), give reasonable advance notice to the other Party of such disclosure requirement and, in the case of each of the foregoing exceptions pursuant to this subsection (iii), will use its reasonable efforts to secure confidential treatment of such Confidential Information required to be disclosed; (iv) to advisors (including lawyers and accountants) on a need to know basis in support of the purposes of this Agreement, in each case under appropriate confidentiality provisions or professional standards of confidentiality substantially equivalent to those of this Agreement; and (v) to the extent mutually agreed to by the Parties. Neither Party will disclose Confidential Information of the other Party to its personnel or to an Affiliate except to the extent such personnel or Affiliate needs to know such information for the performance of such Party’s activities hereunder.

Confidential Treatment of Terms and Conditions. Neither Party will disclose the terms and conditions of this Agreement, except that each Party has the right to disclose the terms and conditions of this Agreement under reasonable and customary obligations of confidentiality (but no less than equivalent obligations to those terms under which the disclosing Party would disclose its own confidential information of similar type): (i) if required by Applicable Law; (ii) to Governmental Authorities with authority over such Party that request to review this Agreement in connection with a review, audit or investigation of the operations of such Party by such authority (and provided that review of the terms of this Agreement are reasonably pertinent to such review, audit or investigation); and (iii) to its attorneys and accountants in support of the purposes of this Agreement. Notwithstanding the foregoing, with respect to complying with the disclosure requirements of any Governmental Authority in connection with any required filing of this Agreement, the Parties will consult with one another

Press Releases. Notwithstanding Section 9.3 (Confidential Treatment of Terms and Conditions), the Parties will issue a joint press release to announce the execution of this Agreement, which is attached hereto as the Press Release Schedule and is for use in responding to inquiries about the Agreement and will agree on the timing in accordance with Applicable Law and method for issuing such press release and any media briefings; thereafter, GSK and Amgen may each disclose to Third Parties (including media interviews and disclosures to financial analysts) the information contained in such press release (but only such information) without the need for further approval by the other, provided that such information is still accurate. Each Party will have the right to issue additional press releases and disclosures in regards to the terms of this Agreement only with the prior written consent of the other Party, such consent not to be unreasonably withheld (or as required to comply with any Applicable Law). For any such proposed press release or disclosure, the disclosing Party will provide [*] notice to the other Party and will reasonably consider the other Party’s comments that are provided within [*] after such notice, or such shorter notice and comment periods as are reasonably required under the circumstances but not less than [*].

Publications and Program Information. The EDC will oversee publications, presentations and public disclosures with respect to Ivory in the Expansion Scope. GSK will have the right to publish with respect to Ivory and to make scientific presentations with respect to Ivory, in each case within the Expansion Scope, subject to Section 4.6 (Conferences in the Expansion Territory) and approval of the EDC. All publications and presentations in the Expansion Scope must be consistent with the publication strategy established by the EDC. GSK may publish the results and summaries of clinical studies with respect to Ivory for the Expansion Scope on clinical trial registries maintained by GSK or its Affiliates, provided that: (i) [*]. The Parties will cooperate to establish timelines and procedures for EDC review of publications and presentations, and publications and presentations in the Expansion Scope will be subject to policies established by the Patent Coordinators to ensure appropriate protection of intellectual property rights.

Attorney-Client Privilege Neither Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges recognized under the Applicable Law of any jurisdiction as a result of disclosing information pursuant to this Agreement, or any of its Confidential Information (including Confidential Information related to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections. The Parties may become joint defendants in proceedings to which the information covered by such protections and

privileges relates and may determine that they share a common legal interest in disclosure between them that is subject to such privileges and protections, and in such event, may enter into a joint defense agreement setting forth, among other things, the foregoing principles but are not obligated to do so.

Injunctive Relief. Given the nature of the Confidential Information and the competitive damage that may result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 9 (Confidentiality, Publications and Press Releases). In addition to all other remedies, a Party is entitled to seek specific performance and injunctive and other equitable relief (without the need to post a bond) as a remedy for any breach or threatened breach of this Article 9 (Confidentiality, Publications and Press Releases).

Additional Permitted Disclosure. [*] will have the right to [*] pursuant to [*].

Acknowledgment. The Parties agree that neither Party is making any representation hereunder with respect to the prospects of Ivory, including that Ivory will achieve any particular clinical or commercial results or will obtain Regulatory Approval(s) in any country(ies) within the Expansion Territory.

INDEMNIFICATION AND INSURANCE

Indemnity by GSK. Subject to the remainder of this Article 11 (Indemnification), GSK will defend, indemnify, and hold harmless Amgen, its Affiliates, and their respective directors, officers, employees, agents and representatives (collectively, “Amgen Indemnitees”), at GSK’s cost and expense, from and against any and all liabilities, losses, costs, damages, fees or expenses (including reasonable legal expenses and attorneys’ fees incurred by or on behalf of any of the indemnitees until such time as the indemnification obligation is acknowledged and assumed hereunder with respect to the applicable claim) (collectively, “Losses”) arising out of any claim, action, lawsuit, or other proceeding (collectively, “Claims”) brought against any Amgen Indemnitee by a Third Party to the extent such Losses result from: [*].

Indemnity by Amgen. Subject to the remainder of this Article 11 (Indemnification), Amgen will defend, indemnify, and hold harmless GSK, its Affiliates, and their respective directors, officers, employees and agents (collectively, “GSK Indemnitees”), at Amgen’s cost and expense, from and against any and all Losses arising out of any Claims brought against any GSK Indemnitee by a Third Party to the extent such Losses result from: [*]. Notwithstanding the foregoing, this Section 11.2 (Indemnity by Amgen) will not apply to any issues related to supply of Ivory by Amgen, which matters are subject to the Supply Agreement.

[*].

Claim for Indemnification. Whenever any Third Party Claim or Loss arises for which a GSK Indemnitee or an Amgen Indemnitee (the “Indemnified Party”) may seek indemnification under this Article 11 (Indemnification), the Indemnified Party will promptly notify the other Party (the “Indemnifying Party”) of the Third Party Claim or Loss and, when known, the facts constituting the basis for the Third Party Claim; provided that the failure by an Indemnified Party to give such notice or to otherwise meet its obligations under this Section 11.4 (Claim for Indemnification) will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that the Indemnifying Party is actually prejudiced as a result of such failure. The Indemnifying Party will have exclusive control of the defense and settlement of all Third Party Claims for which it is responsible for indemnification and will assume defense thereof at its own expense promptly upon notice of such Third Party Claim. The Indemnified Party will not settle or compromise any Third Party Claim for which it is entitled to indemnification without the prior written consent of the Indemnifying Party, unless the Indemnifying Party is in breach of its obligation to defend hereunder. In no event will the Indemnifying Party settle any Third Party Claim without the prior written consent of the Indemnified Party

Defense of Third Party Claims. Except as otherwise provided in Section 11.4 (Claim for Indemnification), each Party (such Party referred to as the “Defending Party”) will have the sole right, but not the obligation, to defend against any Third Party Claims made against it with respect to its activities hereunder. Each Party will notify the other Party (the “Assisting Party”) as promptly as practicable if any Third Party Claim is commenced or threatened against it, including any Infringement Claim or any [*]. The Assisting Party will reasonably assist the Defending Party and cooperate in any such litigation at Defending Party’s reasonable request (and the Defending Party will reimburse the Assisting Party’s reasonable costs incurred in connection with such cooperation). The Defending Party will seek and reasonably consider, but is not obligated to follow, the Assisting Party’s comments before determining the strategy for such matter. Without limiting the foregoing, the Defending Party will keep the Assisting Party advised of all material communications, actual and prospective filings or submissions regarding such action, and will provide the Assisting Party copies of and an opportunity to review and comment on any such communications, filings and submissions; provided, that each Party will have the right to redact from any information disclosed to the other hereunder any information relating to a product other than Ivory or relating to the manufacture of Ivory. The Defending Party will control the defense and/or settlement of Third Party Claims at its own expense with counsel of its choice. The Assisting Party will have the right to participate in the defense and/or settlement of such Third Party Claim at its own expense with counsel of its choice. The Defending Party will not settle a Third

Insurance. Each of the Parties will, at its own respective expense, procure and maintain during the Term insurance policies adequate to cover its obligations hereunder and consistent with the normal business practices of prudent pharmaceutical companies of similar size and scope (or reasonable self-insurance sufficient to provide materially the same level and type of protection). Such insurance will not create a limit to either Party’s liability hereunder.

TERM AND TERMINATION

Term. This Agreement will become effective on the Effective Date and, unless and until sooner terminated pursuant to any provision of this Agreement, will terminate [*] following the Effective Date (the “Term”). If earlier, this Agreement will terminate upon such time as there are no countries remaining in either the Reserved Territory or the Expansion Territory. Upon request of either Party, the Parties will discuss a [*] extension of the Term on the same terms as set forth herein. Any such extension of the Term will only be effective if expressly set forth in a written amendment hereto signed by each Party.

Termination for Breach.

In the event of a material breach of this Agreement, the non-breaching Party will have the right to terminate this Agreement (either as a whole or in the country or countries with respect to which such breach occurred, at the terminating Party’s option) by written notice to the breaching Party, which notice will specify the nature of such breach in reasonable detail. Such termination will become effective on the date specified in the notice (which will not be earlier than [*] after the delivery thereof to the breaching Party or, in the case of a failure to pay amounts due hereunder, [*]) unless, during the [*] period after delivery of such notice to the breaching Party, the breaching Party has cured such breach to the reasonable satisfaction of the non-breaching Party.

Notwithstanding the provisions of Section 12.2.1, the following will apply in the event of multiple breaches by the same Party: (i) in the event of [*] material breaches of this Agreement by the same Party within a [*] period, the non-breaching Party will have the right to terminate this Agreement by written notice to the breaching Party, which notice will specify the nature of such third breach in reasonable detail, effective (regardless of whether such third breach is cured) as of the date specified in such notice (which will not be earlier than [*] from receipt thereof by the breaching Party), and (ii) if a Party commits at least [*] material breaches of this Agreement and such breaches are with respect to the same obligation or activity hereunder, then the non-breaching Party will have the right, but not the obligation, to call a special meeting of the EDC with respect to development breaches or the ESC with respect to any other breach (a “Special Meeting”), by written notice to the breaching Party. Such notice will state with particularity the obligations that the non-breaching Party believes have not been satisfied and the basis for such belief. The Special Meeting will be convened within ten (10) business days of the breaching Party’s receipt of such notice. At the Special Meeting, the ESC or EDC, as applicable, will discuss the non-breaching Party’s concerns, the breaching Party’s efforts in such area of concerns and any additional actions the breaching Party should take to alleviate the non-breaching Party’s concerns. The ESC or EDC, as applicable, will develop a plan describing the actions that the Parties reasonably believe the breaching Party should take to meet its applicable obligations under the Agreement (the “Remediation Plan”); provided, that the Remediation Plan may provide that the non-breaching Party will assume responsibility for such obligation or activity and the breaching Party will cooperate with the non-breaching Party to effect such transition to the non-breaching Party. The applicable Party will perform the actions described in such Remediation Plan in accordance with the timelines, if any, set forth therein. For the avoidance of doubt, if the non-breaching Party chooses not to request a Special Meeting, then such Party may proceed in accordance with Section 12.2.1.

Termination for Insolvency. Either Party will have the right to terminate this Agreement immediately upon written notice, if: (i) the other Party becomes insolvent; (ii) the other Party files a petition in bankruptcy, or if an involuntary petition in bankruptcy is filed against the other Party and such involuntary petition is not dismissed within seventy-five (75) days and the other Party (a) fails to assume this Agreement in any such bankruptcy proceeding within thirty (30) days after filing or (b) assumes and assigns this Agreement to a Third Party; or (iii) a receiver or guardian has been appointed for the other Party who is not discharged within seventy-five (75) days after appointment.

Termination for Challenge. A Party will have the right to terminate this Agreement by written notice to the other Party, if such other Party, its Affiliates or licensees bring or join any challenge to the validity or enforceability of (i) if Amgen is the challenging Party, any Know-How or Patents licensed to Amgen pursuant to Section 8.5 (License Grant by GSK) (including GSK Inventions); and (ii) if GSK is the challenging Party, any Ivory Intellectual Property (or any intellectual property corresponding to any such Ivory Intellectual Property outside the Expansion Scope). Notwithstanding the foregoing, nothing in this Section 12.4 (Termination for Challenge) will either: (i) prevent either Party from asserting any defense or counterclaim in an action for infringement of intellectual property, brought against such Party or its Affiliates, or any Third Party that such Party or any of its Affiliates is obligated to indemnify, or responding in any other manner to such an action for infringement; or (ii) allow a Party to terminate this Agreement in the event the other Party asserts any such defense or counterclaim or otherwise responds in any such action for infringement.

Termination for Change of Control.

Early Change of Control of GSK. GSK will give Amgen written notice within five (5) days after the public announcement or disclosure of, or if earlier the signing of any agreement for, a proposed Change of Control of GSK. In the event of the occurrence of, signing of an agreement for, or public announcement or disclosure of, any proposed Change of Control of GSK (a “Control Event”) prior to the [*] of the Effective Date, Amgen will have the right to [*].

Later Change of Control of GSK. If a Control Event occurs on or after the [*] of the Effective Date, Amgen will have the right to [*].

Change of Control of Amgen. In the event of the occurrence of a Change of Control of Amgen, if [*], then GSK will have the right to [*].

Termination for Withdrawal or Stoppage. If (i) GSK decides to not sell Ivory in a country in the Expansion Scope, or (ii) after receipt of Regulatory Approval for Ivory in a country in the Expansion Scope GSK does not sell Ivory in such country, in either case for a period of [*] for reasons other than Force Majeure, then in any such event GSK will promptly notify Amgen thereof in writing and Amgen will have the right to terminate this Agreement with respect to such country, on [*] prior written notice; provided, that during the [*] notice period, GSK may request that the Parties meet to discuss without obligation, whether, and under what conditions, GSK may be able to commence or continue selling Ivory in such country. Termination under this Section 12.6 (Termination for Withdrawal or Stoppage) is independent of any termination right under Section 12.2 (Termination for Breach) and the occurrence of an event in clause (i) or (ii) of this Section 12.6 (Termination for Withdrawal or Stoppage) will not necessarily constitute a breach hereunder or imply that a breach has occurred hereunder.

Termination for Convenience. GSK will have the right to terminate this Agreement (in its entirety, not on a country-by-country basis) upon [*] prior

Amgen Termination Right.

Buy-Out. Beginning on [*] (the “Buy-Out Date”), Amgen will have the right, on a [*] basis, to terminate this Agreement in such [*] by at least [*] prior written notice to GSK (a “Country Termination Notice”), such termination to be effective no sooner than the Buy-Out Date. During the Term, GSK will provide to Amgen all information reasonably requested by Amgen for it to evaluate and plan with respect to the potential exercise of its termination rights under this Section 12.8 (Amgen Termination Right). In the event of any such termination, Amgen will pay GSK [*].

Buy-In Discussion. In addition to Amgen’s right to terminate under Section 12.8.1 (Buy-Out), beginning on the Buy-Out Date, either Party may request that the Parties meet and discuss, without any obligation, alternatives with respect to the commercialization of Ivory in the applicable [*], which may include continuing to commercialize pursuant to this Agreement, increasing operational participation by Amgen under this Agreement, or entering into a joint venture with respect to such [*] (with respect to Ivory or other products of the Parties). During the Term, GSK will provide to Amgen all information reasonably requested by Amgen for it to evaluate and plan with respect to the potential discussions described in this Section 12.8.2 (Buy-In Discussion).

Effects of Expiration or Termination. Upon the expiration or termination of this Agreement for any reason, the following will apply (to the Expansion Territory as a whole, if the entire Agreement is terminated, or only to the applicable country(ies) if the Agreement is terminated only with respect to a country or certain countries within the Expansion Territory):

Accrued Obligations. Expiration or termination of this Agreement for any reason will not release either Party from any liability (including any payment obligations) that, at the time of such expiration or termination, has already accrued to the other Party or which is attributable to activities prior to such expiration or termination.

Transfer of Materials. With respect to any terminated country within the Expansion Territory, upon Amgen’s request, GSK will transfer to Amgen any inventory of and/or materials related to Ivory, and Amgen will reimburse GSK’s acquisition or reasonable production costs thereof.

Promotion Rights; Licenses. Except as set forth in Section 12.10 (Transition), upon the expiration or termination of this Agreement: (i) GSK’s right to further develop and commercialize Ivory in the Expansion Scope will terminate, (ii) all licenses to GSK hereunder will terminate, and (iii) GSK will immediately cease all of its commercialization and other activities for Ivory in the Expansion Scope and discontinue all use of Amgen Housemarks and Product Trademarks. Amgen will have the right to use the GSK Housemarks incorporated in Ivory materials until such time as any existing inventory of labeling, package inserts or outserts, monographs or packaging materials or Promotional Materials for Ivory in the Expansion Scope that contain the GSK Housemarks have been depleted.

Product Data and Amgen Confidential Information. GSK will promptly transfer to Amgen, at no cost, copies of all data, reports, records and materials in its possession or control that relate to Ivory (“Product Data”). Such Product Data will be in electronic form reasonably usable by Amgen and, if reasonably necessary in connection with Amgen’s (or its designee’s) further commercialization, development or exploitation of Ivory in the Expansion Territory, will include original hardcopies or duplicate copies thereof, as required. In addition (without limiting Section 8.2 (Copyright Ownership; Certain Confidential Information)), all Product Data generated by or under authority of [*] hereunder during the term of the Agreement that solely pertains to [*] following termination of this Agreement. In addition, GSK will promptly return to Amgen, or destroy at Amgen’s request, all relevant records and materials in GSK’s possession or control containing Confidential Information of Amgen (provided that GSK may keep: (i) such copies of such records as may be required for GSK to comply with Applicable Law; and (ii) one copy of such Confidential Information of Amgen, for archival purposes only, provided that, in each case, such copies are Segregated from any [*]).

Return of Materials. GSK will promptly return to Amgen, or destroy at Amgen’s request (and certify such destruction to Amgen), all Promotional Materials, sales training materials and any other documents, or materials primarily intended for use in commercialization of Ivory in the Expansion Territory.

Assignment of Filings and Registrations. Upon request of Amgen, GSK will, at its own expense (other than with respect to any fee payable to the relevant Governmental Authority in connection with the relevant assignment, which will be borne by Amgen), (i) assign to Amgen (or its designee) all Regulatory Filings and Regulatory Approvals in the Expansion Territory related to Ivory that are in GSK’s name (if any) or

withdraw such Regulatory Filings or Regulatory Approvals or take such other action with respect thereto as directed by Amgen, and (ii) assign to Amgen (or its designee) all trademark and Copyright registrations related to Ivory (or to labeling, package inserts or outserts, monographs or packaging materials or Promotional Materials for Ivory) that are in GSK’s name, if any. The foregoing is not meant to imply any right of GSK to own any filing or intellectual property except as may be expressly set forth herein or agreed in writing between the Parties. To the extent permitted by Applicable Law, until each requested Regulatory Filing and Regulatory Approval is assigned to Amgen (or its designee), GSK will hold such filing or approval for the benefit of Amgen and will take all action reasonably necessary or requested by Amgen to provide Amgen with the benefit thereof, including granting Amgen exclusive rights thereunder, providing Amgen with a right of reference and access to all such filings and approvals and notice of and an opportunity to participate in any interactions and correspondence with Governmental Authorities with respect to such filings and approvals.

Survival. Articles 6 (Payments) (with respect to periods prior to expiration or termination), 7 [*] (only with respect to such continuing periods as expressly referenced in such Article), 11 (Indemnification and Insurance), 13 (Miscellaneous) and Sections 5.7 (Product Technical Complaints; Recalls; Returns) (only with respect to Ivory sold by GSK in the Expansion Scope prior to the termination), 5.1.5 (Development Costs) (only with respect to activities undertaken prior to termination), 6.1 (Support Costs) (only with respect to activities undertaken prior to termination), 8.3 (Joint Ownership), 8.4 (License Grant by Amgen) (only with respect to the transition period referenced in Section 12.10 (Transition)), 8.5 (License Grant by GSK), 8.11.3.1 (To GSK) (with respect to the transition period referenced in Section 12.10 (Transition)), 8.11.3.2 (To Amgen) (with respect to the sell-off period referenced therein), 9.1 (Confidentiality; Exceptions), 9.2 (Authorized Disclosure), 9.3 (Confidential Treatment of Terms and Conditions), 9.6 (Attorney-Client Privilege), 9.7 (Injunctive Relief), 12.9 (Effects of Expiration or Termination), 12.10 (Transition), and 12.11 (No Limitation of Rights) will survive expiration or termination of this Agreement for any reason. Following any such expiration or termination, medical inquiries with respect to Ivory will be referred by GSK to Amgen in accordance with instructions provided by Amgen. Except as otherwise provided in this Section 12.9 (Effects of Expiration or Termination), all rights and obligations of the Parties under this Agreement will terminate upon expiration or termination of this Agreement for any reason.

Transition. During all applicable notice periods prior to termination of this Agreement under Sections 12.2 (Termination for Breach), 12.3 (Termination for Insolvency), 12.4 (Termination for Challenge), 12.5 (Termination for Change of Control), 12.7 (Termination for Convenience) 12.8 (Amgen Termination Right) and 13.10 (Force Majeure) (provided, however, that with respect to transition

following termination pursuant to Section 13.10 (Force Majeure), the Party subject to such Force Majeure or [*] will not be liable for activities under this Section 12.10 (Transition) to the extent prevented from performing such activities due to the Force Majeure or [*] giving rise to such termination), GSK will continue to meet its obligations to promote Ivory within the Expansion Scope, in accordance with the Expansion Brand Plan and this Agreement, unless otherwise requested by Amgen. Except for termination pursuant to Section 12.8 (Amgen Termination Right), during such period as the Parties determine is reasonably necessary (up to [*]) following the effective date of such termination, GSK will undertake reasonable efforts to effect a smooth and orderly transition of all commercial activities and responsibilities of GSK under this Agreement to Amgen, as soon as reasonably possible, to enable Amgen to continue the promotion and commercialization of Ivory in the Expansion Scope after termination. Notwithstanding the foregoing, the Parties will use reasonable efforts to effect the transition as quickly as possible within the time periods referenced above. For the avoidance of doubt, in the case of termination in accordance with Section 12.6 (Termination for Withdrawal or Stoppage) for a safety issue, GSK will have no obligation to Detail or commercialize Ivory, or take any other action that it reasonably believes presents a safety risk to patients, but will carry out its other obligations pursuant to Section 12.9 (Effects of Expiration or Termination). During the longer of any such notice period and a [*] period following any termination of this Agreement, GSK will undertake reasonable efforts to effect a smooth and orderly transition of all commercial and other activities and responsibilities of GSK under this Agreement to Amgen, as soon as reasonably possible, to enable Amgen to continue the development, promotion and commercialization of Ivory in the Expansion Scope after termination. During any transition period subsequent to the expiration or termination of this Agreement, Amgen will reimburse GSK’s reasonable costs incurred at Amgen’s request in connection with the transition of responsibilities for Ivory in the Expansion Scope to Amgen. As the case may be, this Section 12.10 (Transition) will apply to the Expansion Territory as a whole if the entire Agreement is terminated, or only to the applicable country(ies) if the Agreement is terminated only with respect to a country or certain countries within the Expansion Territory.

No Limitation of Rights. The rights provided in this Article 12 (Term and Termination) will be in addition and without prejudice to any other rights which the Parties may have with respect to any default or breach of the provisions of this Agreement. Termination is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies at equity or law will remain available to the Parties except as expressly agreed otherwise herein.

Arbitration. In the event of any controversy or dispute arising out of or relating to any provision of this Agreement, the construction, validity or breach thereof, the Parties will try to settle the same amicably between themselves.
