Article 6
Manufacture and Supply

6.1Supply Commitment. AstraZeneca agrees to purchase, and FibroGen WFOE agrees to supply, all of AstraZeneca’s and its Sublicensees’ requirements of Product for Development and Commercialization in the Territory under the terms of this Article 6 and in accordance with this Agreement. All Product supplied to AstraZeneca by or on behalf of FibroGen WFOE under this Agreement will be supplied as finished product.

6.2Covenant. Except as expressly set forth in this Article 6 or the Supply and Quality Agreement or the U.S. and RoW Agreement, AstraZeneca shall not have the right to manufacture any Product anywhere in the world.

6.3Second Source for Drug Substance. At a time to be determined by the JSC, FibroGen WFOE will complete activities to establish and secure Regulatory Approval for a second source for drug substance for Product using a Third Party supplier reasonably acceptable to AstraZeneca, and will thereafter maintain two separate, validated manufacturing sites for such drug substance, one of which will be FibroGen WFOE’s Beijing plant.

6.4Selection of Contract Manufacturer for Drug Product. Upon AstraZeneca’s written request to FibroGen WFOE, which request shall not be submitted earlier than six (6) months after the Effective Date, the Parties will discuss in good faith the selection of a contract manufacturer to be used by FibroGen WFOE to conduct formulation and packaging (using drug substance supplied by FibroGen WFOE) for supply under this Agreement. The Parties shall discuss in good faith the introduction of such contract manufacturer into the supply chain when capacity at FibroGen WFOE’s Beijing plant becomes fully occupied. Such selection will be conducted in accordance with the following process: As soon as reasonably practicable following AstraZeneca’s request, the Parties will afford an opportunity for at least two (2) different Third

29.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Party contract manufacturers that are mutually acceptable to the Parties, consent not to be unreasonably withheld, to submit bids to conduct such manufacture. Such bids shall be based on a request for quotation, the contents of which shall be agreed by the Parties in good faith (and shall contain such specifications and forecasts as are reasonabl y necessary for a contract manufacturer to submit a bid with respect to such manufacture). AstraZeneca shall be afforded an opportunity to submit a bid on the same basis as the Third Party contract manufacturers. The Parties shall review and assess in goo d faith the bids submitted by the Third Party manufacturers and by AstraZeneca and shall recommend to the China Committee the bid that, on the whole, offers the most favorable terms for such manufacture of Product for supply to AstraZeneca under this Agree ment, based on a reasonable assessment of the relevant factors, including price, capital requirements, quality, capacity and capability to maintain continuity of supplies. FibroGen WFOE will enter into a supply and quality contract with the Third Party co ntract manufacturer or (as the case may be) with AstraZeneca, whichever submitted the bid selected by the China Committee, on terms consistent with the selected bid and otherwise reasonably acceptable to FibroGen WFOE. In the event FibroGen WFOE shall cont ract with AstraZeneca in accordance with this Section 6.4, FibroGen WFOE shall, as soon as reasonably practicable after the completion of the selection process, provide the necessary technology transfer and royalty free licenses (if any) as well as all nec essary assistance to obtain required Regulatory Approvals, all to enable AstraZeneca to conduct the formulation and packaging (using drug substance supplied by FibroGen WFOE) for supply of Product under this Agreement. If AstraZeneca is not selected as th e contract manufacturer, then at any time after the [*], then AstraZeneca may request that the selection process set out above in this Section 6.4 shall be repeated. If AstraZeneca so requests, the Parties shall repeat such process, but only after the end of the then-current term of the then-current supply agreement with the Third Party manufacturer.

6.5Supply and Quality Agreement. At a time agreed by the Parties that is reasonably sufficiently early enough to meet the objectives under this Section 6.5, the Parties will negotiate in good faith and enter into separate supply and quality agreements governing the commercial supply of finished product from FibroGen WFOE to AstraZeneca (the “Supply and Quality Agreement”). Such agreements will reflect the terms and conditions set forth on Exhibit K of the U.S. and RoW Agreement and contain such further commercially reasonable terms governing similar supply arrangements and other terms as the Parties may agree, including appropriate forecasting and firm purchase order lead times, taking into consideration the reasonable notice requirements of FibroGen WFOE and its Third Party manufacturers as well as any other terms set forth in this Article 6. In the event of any inconsistency between the Supply and Quality Agreement and Article 6 of this Agreement with regard to matters relating to supply, quality control and quality assurance, the terms of the Supply and Quality Agreement shall prevail.

6.6Product Price. As further described in the Supply and Quality Agreement, prior to establishment of a Product price as approved by the applicable Regulatory Authority, the Parties will determine in good faith an estimated price per unit of Product for the supply of Product to AstraZeneca based on the then-current Commercialization Plan. Once such price is established, the price approved by the applicable Regulatory Authority will be used for such supply, and the Parties shall reconcile the estimated price with the actual price by means of a credit or additional payment, as applicable. Thereafter, COGS will be calculated based on [*] as set forth in the Supply and Quality Agreement.

30.

57.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

(b)Regulatory Materials. AstraZeneca shall transfer and assign to the FibroGen Contracting Party(ies) as directed by FibroGen China all Regulatory Materials and Regulatory Approvals for Products in the Territory, if any, that are Controlled by AstraZeneca or its Affiliates or Sublicensees.

(c)Transition Assistance. AstraZeneca shall, at no cost to FibroGen China, provide reasonable consultation and assistance for a period of no more than one hundred eighty (180) days following the effective date of termination for the purpose of transferring or transitioning to FibroGen China, all AstraZeneca Know-How related to a Product not already in FibroGen China’s possession, and, at FibroGen China’s request, all then-existing commercial arrangements relating specifically to Products in the Territory to the extent reasonably necessary or useful for FibroGen China to commence or continue developing, manufacturing, or commercializing Products, and further to the extent AstraZeneca is contractually able to do so. The foregoing consultation and assistance shall include, without limitation, assigning, upon request of FibroGen China, any agreements with Third Party suppliers or vendors that specifically cover the supply or sale of Products in the Territory, to the extent such agreements are assignable by AstraZeneca. If any such contract between AstraZeneca and a Third Party is not assignable to FibroGen China (whether by such contract’s terms or because such contract does not relate specifically to Products) but is otherwise reasonably necessary or useful for FibroGen China to commence or continue developing, manufacturing, or commercializing Products, then AstraZeneca shall reasonably cooperate with FibroGen China to negotiate for the continuation of such license and/or supply from such entity. In any event, if AstraZeneca is manufacturing bulk or finished Product under an agreement entered into pursuant to Section 6.4, then AstraZeneca shall supply such bulk or finished Product, as applicable, to FibroGen China and Astellas, for a reasonable transitional period (not to exceed twelve (12) months) from the effective date of the termination, subject to reasonable extension by FibroGen China if AstraZeneca is unable to timely effect the technology transfer required to have a Third Party manufacturer designated by FibroGen China undertake the manufacturing responsibilities) under the terms of such agreement until FibroGen China either enters into a separate agreement with such Third Party supplier or vendor or establishes an alternate, validated source of supply for the Products. FibroGen China shall pay to AstraZeneca a price equal to AstraZeneca’s actual cost to manufacture or acquire such supplies, provided that where termination is by AstraZeneca pursuant to Section 13.4(a), FibroGen China shall pay to AstraZeneca a price equal to AstraZeneca’s actual cost to manufacture or acquire such supplies plus a mark-up of [*] of such actual cost.

(d)Ongoing Clinical Trials. As soon as practicable and subject to applicable law, including GCP, AstraZeneca shall transfer to FibroGen China the management and continued performance of all Clinical Trials for Products for the Territory ongoing as of the effective date of such termination that are being conducted by AstraZeneca at such time.

(e)Remaining Inventories. FibroGen China shall have the right to purchase from AstraZeneca any or all of the inventory of Products held by AstraZeneca as of the effective date of termination (that are not committed to be supplied to any Third Party in the ordinary course of business as of the date of termination) at a price equal to AstraZeneca’s actual cost to acquire such inventory. FibroGen China shall notify AstraZeneca within sixty (60) days after the date of termination whether FibroGen China elects to exercise such right. In the event FibroGen China

58.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

does not elect to exercise such right AstraZeneca shall be entitled to dispose of such inventory as it sees fit in compliance wit h applicable law, subject to all applicable payments under Article 8.

(f)Effect of Termination by AstraZeneca at Will. If AstraZeneca terminates this Agreement under Section 13.2 (but not in the event of any other termination), AstraZeneca shall remain responsible for all Development Costs and all Commercialization Costs incurred by FibroGen China under the respective Development Plans and Commercialization Plans during the [*]. If AstraZeneca terminates this Agreement under Section 13.2 (but not in the event of any other termination), then AstraZeneca shall additionally pay (i) to FibroGen Cayman or FibroGen WFOE, as applicable, all reasonable costs to transition any then-ongoing Clinical Trials of Products in the Territory and (ii) to FibroGen Cayman a payment of ten million Dollars ($10,000,000).

(g)Post-Termination Restriction. If this Agreement is terminated by AstraZeneca at will under Section 13.2 or by FibroGen China under Section 13.4 for AstraZeneca’s material breach or by FibroGen China under Section 13.5 for patent challenge, for three (3) years after the effective date of termination, AstraZeneca will not develop, manufacture or commercialize (directly or indirectly), nor license or authorize a Third Party to commercialize, any HIF Compound in the Territory for use in the Field, or knowingly sell or supply HIF Compounds to a Third Party for such purpose.

(h)No Other Rights. For the avoidance of doubt, the rights granted to FibroGen China under this Section 13.6 are restricted to Collaboration Compounds and Products and AstraZeneca does not grant any rights whatsoever to any other compounds or products or to any Patents or other intellectual property rights other than as set forth in this Section 13.6. Moreover, AstraZeneca shall not be obligated to provide FibroGen China with any other intellectual property rights or other rights or services than that which is explicitly provided for under this Section 13.6.

13.7Certain Additional Provisions for Termination for FibroGen China’s Breach.

(a)If this Agreement is terminated by AstraZeneca under Section 13.4 for FibroGen China’s material breach, FibroGen China shall, in addition to any other remedies available to AstraZeneca under this Agreement or applicable law as a consequence of such breach, compensate AstraZeneca for any costs or expenses incurred by AstraZeneca or its Affiliates in connection with performing any of the activities contemplated by the applicable provisions in Section 13.6.

(b)If FibroGen China’s material breach is a material breach of Section 5.7 (Regulatory Compliance), in addition to the rights and remedies set forth in this Agreement, AstraZeneca may, at its option, elect to continue the Agreement, in which case the rights and obligations of the Parties shall continue in full force and effect as described herein, except that (i) at AstraZeneca’s option, FibroGen China’s co-promotion rights shall terminate; and (ii) AstraZeneca shall, as an exception to the decision making principles set forth in Section 2.2(e), have final say over any and all future decision and issues relating to regulatory compliance pursuant to Section 5.7.

13.8 Other Remedies. Termination or expiration of this Agreement for any reason shall not release either Party from any liability or obligation that already has accrued prior to the e ffective date of such expiration or termination, nor affect the survival of any provision hereof to the extent it is expressly stated to survive such termination. Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration.

13.9Bankruptcy. In addition to the termination rights set forth in Sections 13.1 – 13.8 above, a Party shall have the right to terminate this Agreement in its entirety before the end of the Term upon the bankruptcy or insolvency of, or the filing of an action to commence insolvency proceedings against the other Party, or the making or seeking to make or arrange an assignment for the benefit of creditors of the other Party, or the initiation of proceedings in voluntary or involuntary bankruptcy, or the appointment of a receiver or trustee of such Party’s property, in each case that is not discharged within sixty (60) days of the applicable filing, action or initiation of proceedings. In the case of AstraZeneca’s rights under this Section 13.9, such rights shall extend to any of the aforementioned bankruptcy or insolvency events described above occurring in relation to any of the FibroGen Contracting Parties. In addition, if in the Territory an equivalent law to Section 365(n) of the U.S. Bankruptcy Code comes into effect, the Parties shall amend this Agreement as necessary to ensure that each Party as licensee of intellectual property is able to enjoy the full benefits of such law.

13.10Survival.

For any surviving provisions requiring action or decision by a Committee or an Executive Officer, each Party will appoint representatives to act as its Committee members or Executive Officer, as applicable.

15.10Severability. To the fullest extent permitted by applicable law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid or unenforceable in any respect. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by an arbitrator or by any court of competent jurisdiction from which no appeal can be or is taken (within the time period prescribed for appeal), the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof.

Pursuant to the status of the Collaboration as a partnership for such purposes, this Exhibit B provides for the manner in which FibroGen Cayman will cause Capital Accounts to be maintained for each Party and the manner in which the Partnership's items of income, gain, loss, deduction or credit will be allocated among the Parties, in each case solely for United States federal, state, and local income tax purposes. This Exhibit B shall not alter or affect the Parties' obligations to make any payments or to receive any payments under the Agreement. Furthermore the Parties acknowledge and agree that this Exhibit B has no bearing on the Parties’ treatment of the Collaboration for non-US tax purposes, and each Party will be free to take any position or any action with respect to taxes for non-US purposes, whether or not consistent with this Exhibit B.

| (b) | Scope. The Parties acknowledge and agree that this Exhibit B is intended to govern the allocations and reporting of FibroGen Cayman’s items of income, gain, loss, deduction or credit for United States federal, state, and local income tax purposes only, and that consistent with such intention and the purpose stated in Section 1(a) of this Exhibit B, if the provisions of this Exhibit B conflict with any other provisions of the Agreement, the other provisions of the Agreement shall prevail.

2. | Definitions

For purposes of this Exhibit B, the following words and expressions shall have the following meanings respectively given to them:

"Adjusted Capital Account Deficit" means, with respect to any Party, the deficit balance in such Party’s Capital Account as of the end of the relevant taxable period, after giving effect to the following adjustments: (i) credit to such Capital Account any amounts which such Party is deemed to be obligated to restore pursuant to Treasury Regulations Section 1.704-1(b)(2)(c) and pursuant to the penultimate sentences in Treasury Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5); and (ii) debit from such Capital Account the items described in Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) and (6). The foregoing definition of Adjusted Capital Account Deficit is intended to comply with the provisions of Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

"Capital Account" means a capital account established and maintained on behalf of the Partnership for a Party and adjusted in accordance with the provisions of this Exhibit B.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

"Code" means the United States Internal Revenue Code of 1986, as amended. Any reference to a section of the Code shall include a reference to any successor provision thereto.

"IRS" means the United States Internal Revenue Service.

"Treasury Regulations" means the United States federal income tax regulations promulgated under the Code, as such regulations may be amended from time to time (including corresponding provisions of succeeding regulations).

3. | Partnership Accounting Matters

| (a) | Except as otherwise provided in this Section 3(a) of Exhibit B, (i) the amount of any cash payment made by a Party under this Agreement shall be treated as the contribution of an equivalent amount of cash by such Party to the Partnership, and (ii) the amount of any cash payment received by a Party under this Agreement shall be treated as the distribution of an equivalent amount of cash to such Party by the Partnership. Notwithstanding the foregoing clause (ii), the sales milestone payments made by AstraZeneca to FibroGen Cayman pursuant to Section 8.4(a) of this Agreement and the Co-Promotion Profit paid to AstraZeneca under the Co-Promotion Agreement shall be treated as guaranteed payments within the meaning of Code Section 707(c) that are made to FibroGen Cayman or AstraZeneca, respectively, not in their capacity as a partners of the Partnership. For the avoidance of doubt, sales milestones payments made by AstraZeneca to FibroGen Cayman pursuant to Section 8.4(a) of this Agreement and the Co-Promotion Profit paid to AstraZeneca under the Co-Promotion Agreement shall not reduce the Capital Accounts of FibroGen Cayman and AstraZeneca, respectively, and shall result in a corresponding item of Partnership deduction.

| (b) | FibroGen Cayman shall calculate the Partnership's items of income, gain, loss, deduction and credit for each taxable period of the Partnership, using the same methodologies used to calculate Net Profit and Net Loss and Development Costs.

4. | Capital Accounts

| (a) | FibroGen Cayman will cause a separate Capital Account to be established for each Party. The Capital Account of each Party will be adjusted and maintained in accordance with Code Section 704 and Treasury Regulations Section 1.704-1(b)(2)(iv).

| (b) | If the Capital Account of any Party has a deficit balance (after giving effect to all contributions, distributions, and allocations for all periods), such Party will not be obligated to make any payments as contributions to the capital of the Partnership with respect to such deficit, and such deficit will not be considered a debt owed to the Partnership or to any other person for any purpose whatsoever.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

5. | Allocations

| (a) | General. In accordance with the Parties' intention to share Development Costs, Net Profits and Net Losses equally, after giving effect to the allocation set forth in Section 5(b) of this Exhibit B and subject to the application of Section 5(c) of this Exhibit B, all items of Partnership income, gain, loss, deduction and credit for any taxable period shall be allocated fifty percent (50%) to AstraZeneca and fifty percent (50%) to FibroGen Cayman.

| (b) | Qualified Income Offset. In the event any Party unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Party in an amount and manner sufficient to eliminate, to the extent required by Treasury Regulations, the Adjusted Capital Account Deficit of the Party as quickly as possible; provided that an allocation pursuant to this Section 5(b) of Exhibit B shall be made only if and to the extent that such Party would have an Adjusted Capital Account Deficit after all other allocations provided for in this Section 5 of this Exhibit B have been tentatively made as if this Section 5(b) of Exhibit B were not in this Agreement.

| (c) | Loss Limitation. Any items of Partnership loss or deduction allocated pursuant to Section 5(a) of this Exhibit B shall not exceed the maximum amount of items of Partnership loss or deduction that can be allocated without causing any Party to have an Adjusted Capital Account Deficit at the end of any taxable period. In the event one but not both Parties would have an Adjusted Capital Account Deficit as a consequence of an allocation of any items of Partnership loss or deduction allocated pursuant to Section 5(a) of this Exhibit B, the limitation set forth in the immediately preceding sentence of this Section 5(c) of Exhibit B shall be applied and items of Partnership loss or deduction not allocable to a Party as a result of such limitation shall be allocated to the other Party to the extent such items of Partnership loss or deduction can be allocated without causing such other Party to have an Adjusted Capital Account Deficit.

| (d) | Other Allocation Rules.

| (i) | Items of Partnership income, gain, loss or deduction shall be allocated to the Parties pursuant to this Section 5 of Exhibit B as of the last day of each taxable period.

| (ii) | Creditable Foreign Tax Expenditures. The Partnership's “creditable foreign tax expenditures,” within the meaning of Treasury Regulations Section 1.704-1(b)(4)(viii)(b), shall be allocated in proportion to the Parties’ share of the corresponding item of Partnership income, gain, loss and deduction to which such creditable foreign tax expenditure relates.

| (e) | Tax Allocations; Code Section 704(c). Each item of Partnership income, gain, loss, deduction and credit, as determined for United States federal income tax

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

|  | purposes, shall be allocated among the Parties in the same manner as such items are allocated for book purposes to the Parties’ Capital Accounts. In accordance with Code Section 704(c) and the Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property deemed contri buted to the Partnership shall, solely for United States federal income tax purposes, be allocated among the Parties so as to take account of any variation between the adjusted basis of such property to the Partnership for United States federal income tax purposes and its fair market value at the time of contribution, using any method that FibroGen Cayman, in its sole discretion, determines is necessary or appropriate to reflect the purpose and intentions of this Agreement. Allocations pursuant to this Sec tion 5(e) of Exhibit B are solely for purposes of United States federal, state and local income taxes and shall not affect, or in any way be taken into account in computing, any Party’s Capital Account.

6. | Other Tax Matters

| (a) | Tax Filings and Elections. FibroGen Cayman will be responsible for timely causing the Partnership to make the following tax elections and filings:

| (i) | An Internal Revenue Service Form SS-4 (Application for Employer Identification Number) for the Partnership using any name for the Partnership as FibroGen Cayman deems appropriate;

| (ii) | An election under Code Section 6231(a)(1)(B)(ii) to have the TEFRA audit provisions of subchapter C of chapter 23 of the Code apply to the Partnership; and

| (iii) | Any other election for United States federal, state, and local tax purposes that FibroGen Cayman, in its sole discretion, deems necessary or appropriate.

In each case, where any filing identifies AstraZeneca or any Affiliate thereof as partner of the Partnership, FibroGen Cayman will provide a written notice of such filing and a copy of the relevant portion thereof to AstraZeneca at least ten (10) Business Days prior to the proposed submission date for AstraZeneca’s review and approval, such approval not to be unreasonably withheld.

| (b) | Tax Matters Partner. FibroGen Cayman shall serve as the “tax matters partner” of the Partnership for purposes of Code Section 6231 (and any similar provisions under any state, or local tax law). FibroGen Cayman shall promptly notify AstraZeneca if any tax return of the Partnership is audited or if any adjustments to any such return are proposed in writing and shall promptly furnish AstraZeneca with all copies of material documents and notices received in connection with an administrative or judicial proceeding relating to United States income tax matters of the Partnership. FibroGen Cayman will provide a final draft of any tax document to AstraZeneca at least ten (10) Business Days before the date on which such document is to be submitted to the relevant tax authority and will ensure that

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

|  | reasonable comments made by AstraZeneca in relation to such final drafts are considered. FibroGen Cayman shall ensure that AstraZeneca is kept informed in reasonable detail of the progress of, and is consulted in relation to, all tax matters. FibroGen Cayman is authorized to take the following actions, but shall not take any such action without first obtaining the prior written consent of AstraZeneca, which consent shall not be unreasonably withheld.

| (i) | To enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Partnership items (within the meaning of Code Section 6231) required to be taken into account by any Party for United States federal, state or local income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”); and in the settlement agreement FibroGen Cayman may expressly state that such agreement shall bind all Parties, except that such settlement agreement shall not bind any Party (A) who (within the time prescribed pursuant to the Code and Treasury Regulations) files a statement with the IRS providing that FibroGen Cayman shall not have the authority to enter into a settlement agreement on behalf of such Party or (B) who is a “notice partner” (as defined in Code Section 6231(a)(8)) or a member of a “notice group” (as defined in Code Section 6223(b)(2));

| (ii) | In the event that a notice of a final administrative adjustment at the Partnership level of any item required to be taken into account by a Party for United States federal income tax purposes (a “final adjustment”) is mailed to FibroGen Cayman, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the United States Tax Court or the applicable District Court of the United States;

| (iii) | To file a request for an administrative adjustment with the IRS at any time and, if part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

| (e) | Treatment as Partnership. It is the intent of the Parties that the Collaboration between them established by this Agreement be taxed as a partnership for United States federal income tax purposes. Accordingly, the Parties hereby agree not to take any position or any action or to make any election in a U.S. tax return inconsistent therewith. Notwithstanding the foregoing, the Parties acknowledge and agree that this Exhibit B has no bearing on the Parties’ tax treatment or filing in relation to the Collaboration for non-U.S. tax purposes or any activities outside the scope of the Collaboration.

GLOSSARY REFERENCES

1. SCOPE, APPLICATION & INTERPRETATION

1.1 This Policy applies to all Employees and represents the minimum requirements that the Company has set for Interactions.

An alphabetised Glossary containing definitions for all capitalised terms used in this Policy is included at the end of this Policy.

For certain Interactions, You must refer to more than one Section of this Policy. The relevant Sections are cross-referenced as appropriate.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Other Global Policies may also apply to Interactions. For example, the Global Data Privacy Policy applies to Interactions where there is a need to protect the confidentiality of Patient information.

Global Standards may also apply to Interactions. The Global Standards give additional information about what is required to ensure compliance for particular Interactions. The requirements of this Policy and of the supporting Global Standards must be considered as a whole to evaluate and support compliant Interactions. Global Standards are cross-referenced in each relevant section of this Policy.

1.2 This Policy expands on the Company’s Code of Conduct, and aligns with (and in some cases exceeds) the requirements of applicable law and adopted industry codes.

You must follow the spirit of this Policy and not just its letter. The absence of a specific requirement

relating to a particular Interaction does not mean that the Interaction is necessarily permitted; You must avoid any Interaction that breaches the Company’s Code of Conduct or supporting Global Policies, Global Standards or Relevant Procedures.

1.3 Employees must not attempt to avoid the requirements of this Policy by requesting, allowing or enabling Third Parties (including relatives, friends or other associates) to be involved in the Interactions prohibited by this Policy on the Employee’s (or the Company’s) behalf.

In some cases, local law, adopted industry codes particular to a jurisdiction, or rules particular to a Business Unit (e.g., Senior Executive Team (“SET”) function), may apply to Interactions, and may be more restrictive than this Policy. Where that is the case, You must follow the more restrictive rules set out in Relevant Procedures. For example, local marketing organisations must establish Relevant Procedures with respect to Interactions with Public Officials, where local law is more restrictive than this Policy.

To the extent appropriate, Business Units must establish Relevant Procedures to assure compliance with the requirements of this Policy and supporting Global Standards, including requirements for sufficient monitoring and/or audit. Employees must use reasonable judgement to create business records sufficient to demonstrate compliance with the requirements of this Policy, supporting Global Standards and these Relevant Procedures (e.g., business records of required approvals and required rationales for approvals).

For purposes of this Policy, required approvals must be obtained in advance of any Interaction.

Where the scope or interpretation of a particular provision of this Policy, supporting Global Standards or Relevant Procedures is unclear, You should seek guidance from Your line manager or Your relevant Legal and/or Compliance partner.

2. ANTI-BRIBERY & ANTI-CORRUPTION

See Section 7 for prohibitions and other requirements regarding Facilitation Payments, including payments Given under duress.

2.2 You may Give or Receive something of value in compliance with the requirements and

If y ou are in doubt about any Interaction, you must consult with your line manager or your relevant Legal and/or Compliance partner for appropriate guidance.

2.4 All monetary payments by the Company to Third Parties that are permitted by this Policy must be made via an approved Company financial payment system by bank transfer, cheque or company credit card, must not take the form of cash or cash equivalent (e.g., debit cards, gift cards, gift certificates), and must be accurately and appropriately recorded in the Company’s books and records.

All such payments may also be made via a specifically authorised Third Party (unless otherwise noted in this Policy or supporting Global Standards), when genuine business needs require, and Relevant Procedures (with adequate controls) support such an arrangement. In such cases, the Third Party must be contractually obligated to accurately document, track and report to the Company the amounts paid on its behalf, as required by the Relevant Procedures.

This Section 2.4 prohibits cash and cash equivalent payments by Employees (or Third Parties acting on the Company’s behalf), except as specifically permitted by Relevant Procedures established or approved by the Global Finance function.

b) enable or induce a Third Party or fellow Employee to perform their function improperly, or make any decision or take any action favourable to the interests of the Company (or You) on an improper basis, or reward them for doing so;

c) provide incentive or reward to a Third Party for past, present or future willingness to prescribe, administer, recommend, purchase, pay for, reimburse, authorise, approve, supply or use any Company Product or service; or

d) obtain or retain improper business, or secure any improper professional or personal advantage.

2.6 You must not Receive a Bribe.

Receive means to directly or indirectly solicit, agree to receive or accept, or to authorise such actions. You must not Receive something of value from any Third Party or any fellow Employee that is intended or could be seen to:

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

a) compromise Your independence or judgement;

b) enable or induce You to perform Your function improperly, or make any decision or take any action favourable to the interests of the Third Party (or fellow Employee) on an improper basis, or reward You for doing so; or

c) obtain or retain improper business, or secure any improper professional or personal advantage.

3. ITEMS OF VALUE & HOSPITALITY

3.1 You must not Give or Receive Items of Value or Hospitality that are intended or could be seen as improper influence.

To the extent appropriate, Business Units must establish Relevant Procedures on actual or perceived value and frequency when Giving and Receiving Items of Value and Hospitality. These Relevant Procedures must include specific limits on value (modest) and frequency (occasional) and definitions for “modest” and “occasional,” to guide Employees on appropriate value and frequency levels that would not create actual or perceived improper influence, taking into account local custom and practice (See paragraph 2.1 of the Global Standard on Meetings).

To the extent appropriate, Business Units must establish Relevant Procedures to enable the Company to satisfy transparency obligations, with respect to the Giving of Items of Value and Hospitality to External Stakeholders.

Items of Value and Hospitality that exceed Company limits, either separately or in total, to or from the same individual or organisation, are prohibited.

Any Giving or Receiving of Items of Value or Hospitality that is based upon a genuine personal relationship independent of the Company and that is personally funded by the individuals involved (without Company reimbursement) is permissible and is not restricted by this Policy, if it is not intended and could not be seen as improper influence.

3.2 See Section 2 of this Policy and the Global Standard on Items of Value and Hospitality for further requirements on Items of Value and Hospitality.

4. PRICING, DISCOUNTS & REBATES

4.1 To the extent appropriate, Business Units must have an approved pricing model in place, based on objective criteria, to govern the pricing, rebates and discounts (and other commercial advantages or favourable terms) that can be Given to Third Parties.

The pricing model must be reviewed on a regular basis by the head of the relevant Business Unit or designee to ensure appropriateness and transparency.

These Business Units must document the purpose of any prices, rebates or discounts (or other commercial advantages or favourable terms) Given to Third Parties that fall outside the approved

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

pricing model, and this documented purpose must be approved by the head of the relevant Business Unit or designee to e nsure appropriateness and transparency.

4.2 See Section 2 of this Policy for further requirements on prices, discounts and rebates.

5. CONTRIBUTIONS (DONATIONS, SPONSORSHIPS & PARTNERSHIPS)

5.1 The Company is committed to making a positive impact on Our local communities and supporting the work of others in the healthcare and scientific arenas.

Contributions may be classified as Donations, Sponsorships or Partnerships, and may take the form of financial or non-financial support (e.g., funds or in-kind assistance, such as resources, facilities or employee time).

Contributions may generally only be Given for legitimate scientific, educational and/or charitable purposes to support the following: health or healthcare, medical or scientific education, advances in medical or scientific research and disaster relief. Contributions may also be Given for other purposes on an exceptional basis, only with senior management approval, as set out in Relevant Procedures.

For the avoidance of doubt, this Section does not prohibit individual Employees from supporting charities and other organisations in a purely personal capacity and without any involvement of the Company, if the support meets the requirements of Section 8 of this Policy. This Section 5 also does not prohibit Employees from organising charitable efforts on the Company premises (such as a local food drive or book drive), with line manager approval, where Employees use only their personal funds and resources to participate, if the support meets the requirements of Section 8 of this Policy.

Generally, Contributions to support a Meeting or other event must only be Given where the venue and location of the supported event are appropriate and conducive to the intended purpose, and where any Meals or other Hospitality provided by the Company or by the recipient of the Contribution are modest and incidental to the purpose of the event. See the Global Standard on Contributions, the Global Standard on Items of Value and Hospitality and the Global Standard on Meetings for specific requirements and exceptions.

Certain charitable Donations, Sponsorships and Partnerships that meet the relevant criteria described in the Global Standard on Contributions and the Global Procedure and Guidance Community Investment specifically qualify as Community Investment Contributions.

5.2 Contributions may only be given to reputable, recognised and independent institutions or

other legitimate, established organisations, and only for legitimate purposes.

The relevant Business Unit managing the Contribution must conduct appropriate due diligence on the proposed recipient of any Contribution to establish that the proposed recipient satisfies the requirements of this Section 5.2 and to establish that Contribution will be well used. In addition,

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

the relevant Business Unit may agree upfront with the recipient organisation to conduct appropriat e post-funding review (e.g., review of a summary of the completed projects or other results of the

In addition to the requirements of Section 2, a Contribution must not be Given for any other improper purpose or use, including, but not limited to, the following:

a) to help offset an External Stakeholder’s cost of purchasing or reimbursing Company Products or to influence any other decisions about listing, purchasing or reimbursing of Company Products;

b) to organisations or activities that are known to discriminate on any unlawful basis;

c) to support programming or editorial content containing gratuitous violence or sexually explicit material or any activity that does not reflect the values and/or mission of the Company, or could cause embarrassment to the Company; or d) to support any activities prohibited by Relevant Procedures.

Contributions that might be considered as excessive or inappropriate in scale and/or affiliation are not

permitted.

Contributions must not be Given to avoid the restrictions on Giving Items of Value and Hospitality to Third Parties (See Section 3 and the Global Standard on Items of Value and Hospitality).

5.3 Contributions must not be Given to any organisation for the personal benefit of any individual or Healthcare Professional (“HCP”) practice (i.e., a group of HCPs sharing premises or other resources) selected by the Company, or to disguise or conceal any such personal benefit (except as permitted in paragraph 4.5 of the Global Standard on Contributions regarding Fellowships and Preceptorships for scientists to support research activities).

Contributions must not be Given by the Company directly to an individual or HCP practice.

For the avoidance of doubt, direct Company support for individual External Stakeholders to attend Meetings or independent congresses is not considered to be a Contribution for purposes of this Policy and is permissible only in limited circumstances (See section 3 of the Global Standard on Meetings).

For the avoidance of doubt, awards to individuals are not considered Contributions. See the Global Standard on Items of Value and Hospitality for requirements regarding awards and awards ceremonies.

An individual who formally represents an organisation may request a Contribution from the Company on behalf of the organisation, and such request must be considered and processed as

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

required by Relevant Procedures. Contributions must not be Given to an organi sation at the request of any other individual (e.g., to a Public Official’s preferred charity), except for Sympathy Gifts Given to a designated non-profit organisation as a memorial in the event of a death, or Contributions Given at the request of an Emplo yee as part of a Company matching fund programme.

Contributions must not be Given to financially benefit HCPs or HCP practices by replacing any assets or funding any activities that they would be expected or required to provide themselves to fulfil obligations they have under local law, contract or customary business practice. For example, Contributions must not be Given to improve business efficiencies or administrative processes of an HCP or HCP practice, such as support for billing or taxes. For the avoidance of doubt, Contributions to support HCP education are permissible, in the interest of improving Patient care and/or Patient health.

5.4 See Section 2 of this Policy and the Global Standard on Contributions for further requirements on Contributions.

Contributions must not be Given by Third Parties on behalf of the Company, except for Company Product Donations (See the Global Procedure and Guidance Community Investment and the Global Guidance for Product Donations).

For the avoidance of doubt, Contributions do not include Political Support or participation in Political

6. POLITICAL SUPPORT & POLITICAL ACTIVITIES

6.1 Employees must not Give Political Support on behalf of the Company unless specifically authorised to do so by the Government Affairs function or the Reviewer.

Third Parties must not Give Political Support on behalf of the Company under any circumstance. The Company will not reimburse in any way or form any Third Party or non-authorised Employee for Giving Political Support.

Political Support may only be Given where it is expressly permitted by local law and where acceptable as part of local custom and practice.

All Political Support must be Given directly to the recipient organisation or individual. The name of the organisation or individual, purpose, nature and value of the Political Support and the date of the Political Support must be properly documented and recorded in the Company’s books and records, to enable public disclosure.

The Government Affairs function will establish or approve Applicable Internal Review Procedures for the Giving of Political Support.

6.2 Employees and Third Parties must not participate in Political Activities on behalf of the Company unless specifically authorised to do so by the Government Affairs function or the Reviewer.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

The Government Affairs function will establish or approve Applicable Internal Review Procedures for participation in Political Activities.

6.3 The Company recognises the rights of Employees to use their own funds, time and other personal resources to Give Political Support or to participate in Political Activities.

You must ensure that you do not act or appear to act as a representative of the Company when participating in Political Activities or Giving Political Support in a personal capacity. You must make it clear that your views and actions are Your own, and that any Political Support You provide is Given on a personal basis, using Your own funds, time or other personal resources.

6.4 See Section 2 of this Policy for further requirements on Political Support and Political Activities.

7. PAYMENTS TO PUBLIC OFFICIALS & PUBLIC SECTOR ORGANISATIONS

7.1 The Company does not permit Employees or Third Parties providing Services to Give Facilitation Payments, either directly or indirectly, to Public Officials (including HCPs and other individuals employed by Public Sector Organisations), regardless of whether such payments are nominal in amount.

Employees and Third Parties must not attempt to conceal or disguise Facilitation Payments to avoid the requirements of this Section.

The nature of the Company’s business involves legitimate Interactions with a range of Public Officials. Examples include Public Officials responsible for issuing Company Product licences, making Company Product listing decisions, determining Company Product pricing and payment, providing permits and regulatory Authorisations and conducting facility inspections.

You may Give payments to individual Public Officials where they are engaged to provide legitimate Services (See Section 10). You must not Give any other payments to individual Public Officials unless such payments are required or otherwise expressly permitted by local law and not otherwise prohibited by this Policy.

You may Give legitimate and lawful payments to Public Sector Organisations with respect to taxes, permits, licences, inspections and other fees required or otherwise expressly permitted by local law and not otherwise prohibited by this Policy. Official government receipts must be obtained to support all such payments.

7.2 The Company recognises that, in exceptional circumstances, payments may be demanded under duress from Employees or Third Parties providing Services. It is permissible for Employees and Third Parties to Give payments demanded under duress, where there is reasonable fear for personal safety.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Duress describes situations of actual or threatened violence or imprisonment to force a person to act against their will. The Company is committed to ensuring the safety of its Employees an d Third Parties and does not expect them to compromise their safety in such situations.

Employees and Third Parties must promptly report in writing to their line manager all incidents where:

a) Facilitation Payments are requested but not paid; or

b) payments are demanded under duress, whether paid or not.

The line manager must then promptly inform the relevant Legal partner of such incidents in writing and ensure that any payments actually made are properly documented and recorded in the Company’s books and records. The line manager must also consult with the relevant Legal partner regarding the reporting of such incidents to the relevant authorities and the steps to be taken to prevent recurrence.

7.3 See Section 2 of this Policy for further requirements on payments to Public Officials and Public Sector Organisations.

8. AVOIDING CONFLICTS OF INTEREST

8.1 You must ensure that Your interests, activities and associations outside of the Company do not result in actual, apparent or potential Conflicts of Interest with Your professional duties and decisions as an Employee, by directly or indirectly compromising Your independence or professional judgement, or creating an appearance of doing so.

You must not allow, or appear to allow, a personal relationship to influence Your decision-making or judgement. You must ensure that the Company’s interests are paramount when business opportunities are assessed and commercial decisions are taken.

You may make personal financial investments, pursue other business interests and maintain social relationships with people You meet through Your Employment, if all of the relevant requirements of this Section of the Policy are met. You must ensure that these Interactions do not result in actual, apparent or potential Conflicts of Interest with the Company’s business activities.

You must not use Company resources or your position as an Employee for Your own personal benefit or for the benefit of Your relatives, friends or other associates.

8.2 You must inform Your line manager in writing of any actual, apparent or potential Conflicts of Interest at the time they become known. Engagement Owners must also inform their line managers in writing of any actual, apparent or potential Conflicts of Interest of a Third Party providing Services, at the time they become known.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Line managers must provide written direction on how to resolve or avoid the Conflict of Interest after obtaining any necessary advice from the relevant Legal and/or Compliance partner.

If You, a relative or close friend has a financial or management interest in a Third Party (other than a nominal shareholding interest through a publicly-available investment), You must disclose the situation as a potential Conflict of Interest to Your line manager. You must not participate in any purchasing or other Company decisions related to that Third Party.

8.3 You must not do any volunteer or paid work outside of the Company related to Your Company work responsibilities or work product (e.g., speaking engagement, authoring or publishing) unless You obtain written approval from Your line manager, on the basis that such work is unlikely to create an actual, apparent or potential Conflict of Interest and on the basis that any payment is not intended and could not be seen as improper influence.

For all such work, You may Receive necessary and modest travel, accommodation, Meals and other directly related, incidental expenses, with written line manager approval, on the basis that such expenses are not intended and could not be seen as improper influence.

8.4 You must not accept any appointment to the Board of Directors of an external organisation in the healthcare or scientific arena, unless You obtain written approval from Your line manager.

Approval should not normally be provided for directorships of Third Parties who are conducting, or may conduct, business directly within Your scope of responsibility or where You will gain a financial benefit that could be open to question or misinterpretation if publicly disclosed.

8.5 You must not use non-public Company information for personal gain.

You must not pass such information to anyone else (either inside or outside the Company), who does not have a legitimate need for the information.

8.6 See Section 2 of this Policy for further requirements on Conflicts of Interest.

9. MEETINGS

9.1 Organising or supporting Meetings with External Stakeholders is part of Our business. Where doing so, You must follow the requirements listed in the Global Standard on Meetings.

The location, venue, conduct and other arrangements made for Meetings must be modest, conducive and appropriate to the purpose of the Meeting.

9.2 Meetings must always have a scientific, medical education and/or other legitimate business purpose, which must be clearly stated.

The Company may Give a Contribution (See Section 5) to a Meeting organiser to support the conduct of a Meeting (e.g., a Sponsorship). Any such Contribution must meet the relevant requirements of both the Global Standard on Contributions and the Global Standard on

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Meetings, with respect to the substance of the Meeting as well as the conduct and arrangements made for the Meeting.

9.3 See Section 2 of the Policy and the Global Standard on Meetings for further requirements on Meetings.

The Global Standard on Meetings also includes specific requirements on Company support for External Stakeholders to attend independent congresses.

10. ENGAGING THIRD PARTIES & ENSURING COMPLIANCE

10.1 The Company is committed to engaging only those Third Parties who embrace standards of ethical behavior that are consistent with Our own.

Engagement Owners are accountable for ensuring that the Third Party’s reputation and conduct are consistent with the Company’s ethical standards (See Section 10.5).

For the avoidance of doubt, engagements do not include informal, routine business Interactions between Employees and Third Parties, where no Services are provided and no payment is Given (e.g., informal discussions at professional Meetings or independent congresses for scientific exchange, or routine phone calls in the normal course of business).

10.2 Engagement Owners must engage a Third Party only where there is a genuine business need for Third Party Services and must only engage the necessary and appropriate Third Parties to provide those Services.

Engagement Owners must ensure that the selected Third Party has the relevant qualifications, expertise, reputation, knowledge, experience and ability to fulfill the genuine business need, and is the most appropriate choice to provide the Services.

External Stakeholders may be engaged by the Company (either directly or through a specifically authorised Third Party on the Company’s behalf) to provide Services. Such Services include, but are not limited to: providing input and information as an Advisor or consultant, speaking at Meetings (e.g., a Promotional Speaker), acting as a clinical investigator or a study site, or educating or otherwise presenting to Representatives at Representative training or business cycle sessions. Patients and Other Third Parties may also be engaged by the Company to provide Services.

Each engagement with an External Stakeholder or Patient for Services must be documented in a signed contract. If the External Stakeholder or Patient is not accepting compensation, or payment or reimbursement of expenses, the requirement for a signed contract may be waived with documented line manager approval.

Each engagement with Other Third Parties for Services must be documented in the format required for the particular Services to be provided, such as a contract, Terms & Conditions, a Purchase Order or other required documentation of offer and acceptance of Services.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Third Parties must not provide any Service on behalf of the Company, in connection with the execut ion of an engagement or otherwise, unless the Service has been specifically authorised in the signed contract (or other required documentation of the engagement) between the Company and the Third Party, or has otherwise received appropriate documented appr oval.

You must not Give any Payments for Voluntary or Incidental Activities to any Third Party.

10.3 Our Interactions and engagements with External Stakeholders and Patients must at all times be professional exchanges, designed to enhance the practice of medicine, to benefit Patients, or to fulfill a genuine business need.

In no circumstances may the engagement of an External Stakeholder or Patient be used as a means to gain access or to disguise Promotional Activities, or create an appearance of doing so.

10.4 To the extent appropriate, Business Units must establish adequate Relevant Procedures to mitigate the risk of actual or apparent improper influence over individual External Stakeholders engaged to provide Services, and for monitoring compliance.

To the extent appropriate, Business Units must establish Relevant Procedures that include Fair Market Value guidelines, as well as limits on aggregate compensation provided to individual External Stakeholders and limits on frequency of engagement of individual External Stakeholders. The scope of such guidelines and limits ultimately established will vary, based upon locality and/or function. In developing Fair Market Value guidelines, these Business Units must consider local established compensation levels, varying levels of expertise and/or prominence of Third Parties, varying types and durations of Services to be provided, and the spirit and principles of this Policy.

Third Parties must be paid compensation consistent with and no greater than Fair Market Value, taking into account individual qualifications, experience, ability and reputation, and only for the Services actually provided, consistent with the terms of the engagement.

To the extent appropriate, Business Units must establish Relevant Procedures to enable the Company to satisfy transparency obligations, with respect to payments made to External Stakeholders.

10.5 Prior to the selection and engagement of a Third Party, Engagement Owners must conduct appropriate and proportionate risk assessments, as well as associated, due diligence procedures (if necessary), according to Relevant Procedures. Engagement Owners must take these steps to ensure that the Third Party’s reputation and conduct relating to the execution of the engagement are consistent with the Company’s ethical standards, with respect to all relevant areas of risk.

To the extent appropriate, Business Units must establish Relevant Procedures to guide Engagement Owners on how to assess, develop, communicate, implement and enforce required compliance expectations for Third Parties. Required compliance expectations will vary, based upon the nature of the Third Party, the Services to be provided and the nature of the associated risks. Based upon the risk assessment and outcomes for a particular Third Party, Engagement

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Owners may be required to implement one or more of the following actions with respect to that Third Party:

a) improvement plans or action plans;

b) monitoring or auditing requirements;

c) contractual obligations, including written assurances or commitments by the Third Party;

d) provision of Global Policies, Global Standards, Relevant Procedures or other reference materials, and/or associated training;

e) prior review of the engagement or aspects of the engagement or Services from the relevant Legal and/or Compliance partner; and/or

f) other actions to mitigate identified areas of risk, such as contractual risk mitigation clauses.

At a minimum, Engagement Owners must not engage a Third Party where it is known, or where there is a reason to believe, that the Third Party has Given or Received Bribes, unless the Engagement Owner has documented his/her satisfaction with all of the following, in consultation with the relevant Legal and/or Compliance partner:

a) the actions and improvements undertaken by the Third Party to remediate the concerns and/or behaviour;

b) the current level of compliance by the Third Party; and

c) evidence of the Third Party’s ability to provide strong governance and monitoring and to prevent future occurrences of such concerns and/or behaviour.

Engagement Owners, in consultation with an appropriately senior level of management, must periodically reassess existing Third Party relationships, following the required timeframes outlined in the Relevant Procedures, and taking into account any unanticipated changes in the conduct, reputation or risks related to the particular Third Party.

10.6 See Section 2 of this Policy for further requirements on Engaging Third Parties. Engagement Owners must also refer to the Global Standard on Engaging Third Parties for further requirements, prior to entering into any engagement with a Third Party.

11. PROMOTIONAL & NON-PROMOTIONAL ACTIVITIES & MATERIALS

11.1 A key part of Our business is to provide information about Company Products and, where and when appropriate, to Promote their use. Promotional and Non-Promotional

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Activities and Materials must always be accurate, fair and balanced and not misleading in their content.

The Company has a duty to support the safe and effective use of Company Products. While the Company cannot provide medical advice to External Stakeholders or Patients, the Company may engage in Promotional and Non-Promotional Activities where this is appropriate and permitted by local law. For example, Promotional and Non-Promotional Activities directed to Patients (i.e., “direct to consumer” activities) may only be undertaken where this is permitted by local law.

Our activities must never undermine the relationship between HCPs and their Patients. All Promotional and Non-Promotional Activities and Materials directed to HCPs or Patients must therefore support HCPPatient Interactions and must allow the therapeutic value of Company Products to be assessed by HCPs in the interest of Patient care.

Promotional and Non-Promotional Materials about Company Products directed to Patients must be understandable, taking into account varying levels of education between and within populations. These Materials must be educational, scientific and balanced, and should encourage the Patient to seek further information from the appropriate HCP.

The Company may display Promotional or Non-Promotional exhibits, either in conjunction with a Meeting or as a stand-alone activity, according to the requirements included in Relevant Procedures. See the Global Standard on Meetings for further requirements on exhibits (with or without a Meeting).

11.2 The Company must only Promote Company Products once the time is right to do so (which will never be before the Company Product or Use has received the necessary Authorisation), and only consistent with the approved labeling.

Promotional Activities and Promotional Materials must meet all of the following requirements:

a) They must provide a fair balance between a Company Product’s benefits and its risks or limitations. They must not exaggerate the benefits or downplay the risks or limitations;

b) They must not mislead by distortion, exaggeration, undue emphasis, omission or in any other way, and must not involve false or unapproved statements about other companies’ products. Company Products must only be Promoted on their own proven merits; and

c) They must be capable of substantiation by reference to the approved labeling or scientific evidence consistent with the approved labeling, and must not involve discussions of Unauthorised Company Products or Uses.

Representatives and other Employees in customer-facing roles (e.g., public relations, telemarketing, Marketing, Medical) must be trained as appropriate to their role and must do all of the following in an accurate, responsible manner:

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

a) They must possess sufficient Company Product and disease area knowledge to present information

to External Stakeholders or Patients, as appropriate to their role; and

b) They must be able to recognise inquiries regarding Unauthorised Company Products or Uses and refer these inquiries to Scientifically Trained Personnel.

All training and educational materials must be approved through the Applicable Internal Review Procedures.

Representatives and other Employees in customer-facing roles must have available a copy of the current, approved labeling for each Company Product or Use discussion they initiate with External Stakeholders.

Any revisions to the approved labeling must be communicated to Representatives and other relevant customer-facing Employees as soon as reasonably possible.

Promotional Activities that are directed to External Stakeholders must be confined to those individuals who are recognised practitioners in the area of medicine concerning Authorised Company Products or

Uses.

Promotional Activities and Promotional Materials must not be directed to External Stakeholders who have requested that they not be sent such information.

11.3 Non-Promotional Activities and Materials (including those regarding disease awareness programs) must not be used to Promote Company Products. Non-Promotional Activities and Materials must be presented in an objective, balanced manner, and must be scientific in tone, language, appearance and intent.

Where local law allows the Company to respond to Company Product-related questions from Patients, any such response may only be made by Scientifically Trained Personnel or other specifically authorised Employee or Third Party, according to Relevant Procedures. Patients communicating with the Company must not be given medical advice, but must instead be referred to their HCP.

Specifically authorised Employees are permitted to proactively issue press releases or other Non-Promotional Materials, such as those relating to financial or investor information.

Scientifically Trained Personnel are permitted to proactively present scientific data or findings regarding Authorised or Unauthorised Company Products or Uses with a view to generating further scientific insight, supporting the medical community in learning about scientific/medical progress or sharing information on current medical practice, such as at scientific congresses or similar events.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

All inquiries concerning Unauthorised Compan y Products or Uses (whether from External Stakeholders or Patients) must be referred to Scientifically Trained Personnel. All responses to such inquiries, either oral or written, must then come directly and only from such Scientifically Trained Personnel, and must meet all of the following requirements:

a) Information must only be provided in response to unsolicited inquiries;

b) Information must be accompanied by the approved labeling, as applicable;

c) All responses must be limited to the scope of the inquiry and must provide data which are appropriate to the source of the inquiry; and

d) All responses must contain (as relevant) a statement that the information requested involves an Unauthorised Company Product or Use and that the Company does not recommend Unauthorised Uses of the Company Product.

11.4 Promotional Materials and Non-Promotional Materials must be approved through the Applicable Internal Review Procedures. Any modification to approved Promotional or Non-Promotional Materials must also be approved through the Applicable Internal Review Procedures.

You must not create, use or provide “home-made” or other unapproved Promotional or Non-Promotional Materials on any topic. You must not alter any approved Promotional or Non-Promotional Materials in any way, unless such creation or alteration is for the express purpose of submitting these Materials for review and approval.

Promotional and Non-Promotional Materials must be assigned an expiration date upon approval, must be monitored for expiration date and must not be used after the expiration date specified in the original approval, unless they are formally re-approved through the Applicable Internal Review Procedures.

Promotional and Non-Promotional Materials must be accompanied by the approved labeling where applicable, as required by Relevant Procedures.

12. PRE-AUTHORISATION ACTIVITIES & MATERIALS

12.1 It is permissible to engage in Pre-Authorisation Activities (i.e., Profiling, Market Access and Pre-Authorisation Training activities), and to use materials supporting such activities, to prepare for a successful commercial launch of a Company Product or Use. Pre-Authorisation Activities must not be used to disguise Pre-Authorisation Company Product Promotion, or create an appearance of doing so.

Materials used for Pre-Authorisation Activities must be approved through the Applicable Internal Review Procedures.

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

12.2 Relevant Employees (e.g., Employees in the Marketing, Medical or Sales functions) and specifically authorised Third Part ies may Profile customers prior to Authorisation of a new Company Product or Use, to assist in segmentation and targeting activities.

Profiling Activities may only be conducted if all of the following requirements are met:

a) Employees engaging in Profiling must use materials (e.g., scripts) that have been approved through the Applicable Internal Review Procedures;

b) These materials must be structured to allow for a brief conversation to collect broad information about an External Stakeholder’s involvement in a disease area, such as treatments and classes used (e.g., “What classes do you use to treat this disease state?”), as well as their needs and the needs of their Patients;

c) These materials must contain clear instructions on proper execution. These materials must contain a clear, prominent prohibition against engaging in Promotional Activities about the new Company Product or Use during a Profiling conversation;

d) These materials must not contain targeted questions that are specific or unique to a Company Product or Use;

e) If asked by the External Stakeholder about the purpose of the Employee’s questions, Employees may objectively state that the Company has submitted a Company Product or Use for regulatory Authorisation. Employees must not proactively discuss the Company Product or Use in any further detail; and

f) In the event that the External Stakeholder asks for more details about the Company Product or Use during a Profiling discussion, Employees (other than those in the Medical function) may provide appropriate contact information for the External Stakeholder to submit his/her own request for such information (i.e., a “professional information request”), but such Employees must not directly respond to the request or submit the request on behalf of the External Stakeholder. Employees in the Medical function may directly respond to the request and may submit a professional information request on behalf of the External Stakeholder.

During, and in support of, internal Company segmentation and targeting activities, relevant Employees may share existing knowledge and review and share prescribing data and other Company-purchased or publicly available information.

For the avoidance of doubt, Profiling activities are also permitted after Authorisation of a new Company Product or Use.

12.3 Relevant Employees other than Representatives or their first line managers (e.g., Employees in the Market Access or Medical functions) and specifically authorised Third Parties may perform Market Access activities prior to Authorisation of a new Company Product or Use, by providing Company Product or relevant disease area information to

[*] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would likely cause competitive harm to the company if publicly disclosed.

Healthcare Organisations (“HCOs”) (i.e., payers) or Public Officials to support regulatory Authorisation, pricing or rei mbursement discussions.

For the avoidance of doubt, Market Access activities are also permitted after Authorisation of a new Company Product or Use.

12.4 Pre-Authorisation Training on Unauthorised Company Products or Uses may be initiated as necessary to allow for sufficient time to study and understand the new information presented regarding the Company Product or Use, disease area, disease management, External Stakeholder and Patient needs and/or the current market, including the current state of medical practice, competitors and existing therapies, and treatment protocols and Guidelines.

In making the determination of the timing and sequencing of Pre-Authorisation Training for a particular new Company Product or Use (as a guideline, no longer than 60 days before the expected Authorisation date), the Reviewer must seek input from Employees in the Medical, Training, Commercial, Compliance and/or Legal functions (“contributing functions”), as applicable, and must take into account all of the following considerations:

a) whether the training will involve a new or familiar disease area;

b) whether the training will involve an Unauthorised Company Product or an Unauthorised Use of an Authorised Company Product;
