If either such Product that contains the Collaboration Compound(s) as its sole active ingredient or a product that contains the active ingredient(s) (other than the Product) in the Combination Product as its sole active ingredient(s) is not sold separately in a particular country, the Parties shall negotiate in good faith a reasonable adjustment to Net Sales in such country that takes into account the medical contribution to the Combination Product of and all other factors, including patent coverage, reasonably relevant to the relative value of the Collaboration Compound(s) on the one hand and all of the other active ingredient(s), collectively, on the other hand.

In the case of pharmacy incentive programs, hospital performance incentive programs, chargebacks, disease management programs, similar programs or discounts on portfolio product offerings, all rebates, discounts and other forms of reimbursements shall be allocated among products on the basis on which such rebates, discounts and other forms of reimbursements were actually granted or, if such basis cannot be determined, in accordance with AstraZeneca’s, its Affiliates’ or its or their Sublicensees’ existing allocation method; provided that any such allocation shall be done in accordance with applicable law, including any price reporting laws, rules and regulations.

Net Sales will be calculated using AstraZeneca’s internal audited systems consistently applied to report such sales as adjusted for any of the deductions set forth above not taken into account in such systems. Deductions pursuant to item (d) above will be taken in the Calendar Quarter in which such sales are no longer recorded as a receivable.

Any free of charge disposition or use of reasonable quantities of a Product, up to the amount determined by the JCC, for regulatory or marketing purposes (it being understood and agreed that neither Party shall have the right to distribute the Product as samples except pursuant to Section 5.7) such as compassionate use or indigent patient programs, will not be deemed a sale or disposition for calculating Net Sales. Sales and other transfer of Product between any of AstraZeneca, its Affiliates and Sublicensees will not give rise to Net Sales except if the purchaser is an end user.

Such Executive Officers shall use good faith efforts, in compliance with Section 2.6(d), to resolve promptly such matter, which good faith efforts shall include at least one meeting (in-person, by telephone, video conference or other appropriate means) between such Executive Officers within twenty (20) Business Days after the JSC’s submission of such matter to them. If the Executive Officers are unable to reach consensus on any such matter within such twenty (20) Business Day period, then either Party may invoke the dispute resolution provisions of Article 14; provided, however, that:

(1) FibroGen’s Executive Officer shall have the final say with respect to: [*];

(ii) AstraZeneca’s Executive Officer shall have the final say with respect to: [*];

(d) Good Faith. In conducting themselves on Committees, and in exercising their rights under this Section 2.6, all representatives of both Parties shall consider diligently, reasonably and in good faith all input received from the other Party, and shall use reasonable efforts to reach consensus on all matters before them. In exercising any decision making authority granted to it under this Article 2, each Party shall act based on its good faith judgment of what is in the best interests of the Products and the Collaboration.

2.7 Alliance Managers. Each Party shall, within thirty (30) days following the Effective Date, appoint a single person who shall oversee contact between the Parties for all subject matter related to the Collaboration between meetings of the JSC, JPT, JDC and JCC, and shall have such other responsibilities as the Parties may agree in writing after the Effective Date (such person, the “Alliance Manager”). Each Party may replace its Alliance Manager at any time by notice in writing to the other Party. The Alliance Managers shall work together to manage and facilitate the Collaboration governance meetings and the communication between the Parties under this Agreement, including the resolution (in accordance with the terms of this Agreement) of issues between the Parties that arise in connection with this Agreement. The Alliance Managers shall not have final decision-making authority with respect to any matter under this Agreement.

2.8 General Committee Authority. Each Committee shall have solely the powers expressly assigned to it in this Article 2 and elsewhere in this Agreement. No Committee shall have any power to amend, modify, or waive compliance with this Agreement (or any agreement entered into in connection with this Agreement). It is expressly understood and agreed that the control of decision-making authority by FibroGen or AstraZeneca, as applicable, pursuant to Section 2.6, so as to resolve a disagreement or deadlock on a Committee for any matter will not authorize either Party to perform any function not delegated to a Committee, and that neither FibroGen nor AstraZeneca shall have any right to unilaterally modify or amend, or waive its own compliance with, the terms of this Agreement.

24.

2.9 Joint Project Team. The Parties hereby establish a joint project team (the “Joint Project Team” or “JPT”) to develop and propose plans to governing committees, manage operational activities and serve as an information resource for the Committees. The members of the JPT representing core functions relevant to the joint development and commercialization of Products (the “Core Joint Project Team” or “Core JPT”) shall provide oversight to the overall JPT. Until such time as when the JDC and the JCC have been formed, the Core JPT shall have the additional responsibilities set out in Schedule G(a) and G(b), respectively. Neither the JPT nor the Core JPT will have any decision-making authority, except as set out in Schedule G(a) or G(b) or otherwise explicitly authorized by an appropriate Committee. The Parties agree to establish a JPT Charter on or prior to October 31, 2014, which contains the composition and responsibilities of the JPT and the Core JPT. Subject to the JPT Charter, the Core JPT will consist of project leaders as appointed by FibroGen and by AstraZeneca, and such additional members as the Parties deem appropriate from time to time. Each Party will appoint appropriately qualified and authorized representatives for each applicable operational area or function. The JPT members will serve as the point of contact for operational matters between the Parties. The JPT may form subteams to support the efforts of the JPT as agreed by the Parties. As appropriate, FibroGen may arrange, on its own initiative or at AstraZeneca’s reasonable request from time to time, a joint meeting between the JPT and the project team under the Astellas Collaboration.

2.10 Executive Meetings. FibroGen’s Chief Executive Officer and an appropriate Executive Vice President of AstraZeneca (or other appropriate representative of AstraZeneca of equivalent seniority) will meet in advance of the occurrence of key scheduled Development and Commercialization events or in connection with key decisions, to review and discuss the status and direction of the Collaboration.

2.11 Discontinuation of Participation on a Committee. Each Committee shall continue to exist until the first to occur of (a) the Parties mutually agreeing to disband the Committee, or (b) FibroGen providing to AstraZeneca written notice of its intention to disband and no longer participate in such Committee, which FibroGen retains the right to do at any time during the Term, in its sole discretion, provided, however, that doing so shall not relieve FibroGen of any of its obligations under this Agreement or the China Agreement (save from the obligation to participate at the relevant Committee meetings). Once FibroGen has provided written notice as referred to in subsection (b) above, such Committee shall have no further obligations under this Agreement and AstraZeneca shall have the right to solely decide, without consultation, any matters previously before such Committee, subject to the other terms of this Agreement.

ARTICLE 3

DEVELOPMENT

3.1 Overview. The Parties agree to undertake a joint development program to further Develop the Collaboration Compounds and Products as provided in this Article 3 under the direction of the JDC (or, the JSC prior to the inception of the JDC), and pursuant to the Development Plan (such program, the “Development Program”). Prior to the JDC’s inception, all

25.

references to the JDC in this Article 3 and elsewhere in this Agreement will be deemed references to the JSC (which may delegate certain responsibilities to the Core JPT in accordance with Schedule G(a)).

3.2 Development Plans.

(a) General. All Development of any given Product pursuant to this Agreement for the U.S. and RoW shall be conducted pursuant to a development plan (the “Development Plan”) that describes (i) the proposed overall program of Development for the applicable Product and indications in the U.S. and RoW, including Clinical Trials and Nonclinical Studies, toxicology, formulation, packaging development, process and analytical development, production of registration and validation batches, regulatory plans and other elements of obtaining Regulatory Approval(s) in each applicable country; (ii) the anticipated start dates and data availability dates of such Clinical Trials, Nonclinical Studies and CMC development activities, and timelines for key Regulatory Authority meetings, filing of applications for Regulatory Approval, and the receipt of Regulatory Approvals and (iii) the respective roles and responsibilities of each Party in connection with such activities. The Development Plan will be associated with a detailed budget for all such activities conducted by the Parties for the U.S. In the event of any inconsistency between the Development Plan and this Agreement, the terms of this Agreement shall prevail.

(b) Initial Development Plan. The initial Development Plan, along with the associated Development Budget, describing (among other things) the planned development of the Product for the CKD Indications for the U.S., is attached hereto as Exhibit H (the “Initial Development Plan”). The Initial Development Plan includes and shall be integrated with those Phase 3 Clinical Trials that are currently being conducted by FibroGen or Astellas under the U.S. and EU plan for conducting Phase 3 Clinical Trials of the Product for the CKD Indications under the Astellas EU Agreement (the “Transatlantic Clinical Development Plan” or the “TCDP”). FibroGen shall notify AstraZeneca, via the JDC, of all material updates and material changes to the TCDP. The Initial Development Plan shall further outline such additional Phase 3 Clinical Trials as the Parties have agreed to conduct (i.e. in addition to those being conducted under the TCDP). Within thirty (30) days after the Effective Date, the JPT will initiate implementation of the Initial Development Plan.

(c) Development Strategy. Within one (1) year after the Effective Date or at such other time as the Parties may mutually agree, the JDC will prepare for the JSC’s review and approval an overall development strategy for the Product in the Field in the Territory, including the CKD Indications for the RoW and any other indications (or other life cycle management) the Parties are considering to develop (or conduct) throughout the Territory, which strategy will include anticipated dates (estimated based on the date of completion of certain development events) for preparing detailed descriptions of applicable events for inclusion in an amended Development Plan (the “Development Strategy”). The Development Strategy will include reasonable timeframes for any additional indications (i.e., in addition to the CKD Indications) to be developed hereunder, with the understanding that not all such indications will be developed concurrently.

26.

(d) Amendments to the Development Plan.

(i) On an annual basis (no later than October 31^st of the preceding Calendar Year), or more often as the Parties deem appropriate, the JDC shall prepare amendments to the then-current Development Plan and Development Budget for approval of the JSC. Each such amended Development Plan shall specify, with a reasonable level of detail, the items described in Section 3.2(a). Such amended Development Plan shall cover the next Calendar Year (and additional periods as reasonably determined by the Parties) and shall contain a corresponding budget for U.S. activities. Such updated and amended Development Plan shall reflect any changes, re-prioritization of studies within, reallocation of resources with respect to, or additions to the then-current Development Plan. In addition, the JDC may prepare amendments for approval of the JSC to the Development Plan and corresponding Development Budget from time to time during the Calendar Year in order to reflect changes in such plan and budget for such Calendar Year, in each case, in accordance with the foregoing. At the request of either Party, but no more frequently than quarterly, the JDC shall review the Development Budget and propose any necessary amendments to the JSC for approval. Once approved by the JSC, the amended annual Development Plan and Development Budget shall become effective for the applicable period on the date approved by the JSC (or such other date as the JSC shall specify). Any JSC-approved amended Development Plan and Development Budget shall supersede the previous Development Plan and Development Budget for the applicable period.

(ii) Each Party shall notify the other Party promptly upon becoming aware that it is likely to exceed, or has exceeded, the budget for a particular activity for U.S. Development of the Product allocated to such Party in the Development Plan. Thereafter, the JDC shall promptly meet and determine whether to amend the Development Plan or Development Budget accordingly, provided that the JDC shall not unreasonably withhold its agreement to any budget amendment proposed by either Party that results from causes outside of such Party’s reasonable control or that the Parties agree includes expenses reasonably incurred in the performance of the Development Plan. Any such amendment proposed by the JDC shall not be subject to the JSC’s review and will be deemed automatically approved by the JSC, unless such amendment would cause the total Development Costs incurred by a Party in any Calendar Year to exceed [*] percent ([*]%) of the budgeted Development Costs for such Party in such Calendar Year, in which event JSC approval will be required; provided that the JSC shall not unreasonably withhold its agreement to any budget amendment proposed by either Party that results from causes outside of such Party’s reasonable control and that the Parties agree includes expenses reasonably incurred in the performance of the Development Plan.

(e) Development Responsibilities. Unless the Parties agree in writing upon an alternate allocation of responsibility, the Parties shall have the following rights and obligations with respect to operational responsibilities under each Development Plan:

(i) U.S. Operational responsibility for all studies designed to support Regulatory Approvals in the U.S. will be shared between the Parties as allocated in the Development Plan; provided that FibroGen and Astellas (it being agreed that as between the Parties FibroGen will be responsible for all such activities conducted by Astellas; provided however, that [*] Astellas [*] Astellas [*] FibroGen [*] this Agreement [*] FibroGen [*] under the Astellas Agreements with respect to such activities) will be responsible for conducting the first

27.

Phase 3 Clinical Trials (that are included also in the TCDP) of the Product in the CKD Indications under the Initial Development Plan. For clarity, the term ‘first Phase 3 Clinical Trials’, as used in this section, shall be the studies identified as [*] in the Initial Development Plan.

(ii) RoW. AstraZeneca shall be solely responsible for all aspects of the Development of Collaboration Compounds and Products that are solely applicable to the RoW (which, for clarity, does not include China).

(iii) Development Sharing Period. During the Development Sharing Period, FibroGen shall conduct all Development in good faith, and using Commercially Reasonable Efforts to achieve the then-current timelines in such Development Plan.

(f) Development Decision-Making. Except as otherwise expressly provided in this Agreement, all matters regarding the Development Plan shall be decided by consensus by the JDC, subject to Section 2.6.

3.3 Coordination with Astellas.

(a) AstraZeneca understands and agrees that FibroGen’s and AstraZeneca’s conduct of certain Development and Commercialization activities for North America (meaning the U.S., Mexico and Canada) hereunder are subject to the terms of the Astellas EU Agreement, and that FibroGen’s obligations to Astellas may require additional procedures, consents or adherence to notification obligations. Accordingly, the Parties shall, as applicable, take into consideration such obligations when formulating the plans for, and coordinate, [*], and FibroGen shall use Commercially Reasonable Efforts to obtain [*] Development in the Territory under this Agreement. [*]. Notwithstanding anything else in this Agreement to the contrary, however, FibroGen shall not be required to perform (or refrain from performing) any Development activity that would constitute a violation of its obligations under the Astellas Agreements, as disclosed to AstraZeneca prior to the Effective Date.

(b) If, [*], FibroGen shall promptly notify AstraZeneca and such matter shall be discussed at a specially convened JSC meeting. In the event that AstraZeneca, pursuant to Section 3.9, both (i) is not obligated to use Commercially Reasonable Efforts to Develop such Product in such indication; and (ii) following notification by FibroGen, determines that it does not wish to participate in such Development in such indication, the following shall apply:

(i) FibroGen shall be free to Develop, obtain Regulatory Approval for and Commercialize such Product in such indication throughout the Territory;

(ii) As between the Parties, such Development and Commercialization shall be undertaken at FibroGen’s sole cost;

(iii) FibroGen shall use Commercially Reasonable Efforts to ensure that such Development and Commercialization shall not materially impact AstraZeneca’s rights under this Agreement (it being understood that such Development and Commercialization are not considered per se to materially impact AstraZeneca’s rights under this Agreement);

28.

(iv) The Parties shall, as soon as practicable, discuss in good faith an option arrangement whereby AstraZeneca may obtain rights to such Product in such indication at a future decision point. The Parties shall negotiate in good faith the terms under which AstraZeneca would obtain such rights, which terms include [*] and [*]; and

(v) The Parties shall discuss in good faith, appropriate amendments to the provisions of this Agreement to reflect such Development and Commercialization of such Product in such indication by FibroGen, including, without limitation, amendments to the pharmacovigilance provisions in Section 4.3. If the Parties fail to agree on such terms within a reasonable time period, either Party may refer the matter to the Executive Officers for discussion.

(c) The Parties shall ensure that each amended Development Plan allows for the conduct of such Clinical Trials as are included in the then current TCDP. If the JDC agrees that additional studies (i.e. in addition to those included in the TCDP) are required for the Product in the CKD Indications for the U.S., then the Parties shall, where required, [*]. FibroGen shall use Commercially Reasonable Efforts to [*], shall use Commercially Reasonable Efforts to [*].

(d) FibroGen shall use Commercially Reasonable Efforts from time to time during the Term to [*] or other rights that AstraZeneca or the Parties reasonably believe [*] in order to allow AstraZeneca to obtain the benefit of its rights and licenses pursuant to this Agreement.

3.4 Development Costs.

(a) Allocation. The Parties shall share equally all costs and expenses incurred by or on behalf of either Party to conduct Development of the Product for the U.S. under the Development Plan during the Development Sharing Period, according to the terms of Section 8.2, including for supply of Collaboration Compound or Product in accordance with Article 6, in each case to the extent that such Development Costs are not borne or reimbursed by Astellas under the Astellas EU Agreement, provided that FibroGen will timely inform AstraZeneca of any such costs borne or reimbursed by Astellas. AstraZeneca shall be responsible for all costs and expenses it incurs in the conduct of activities under the Development Plan for the RoW and shall reimburse FibroGen for all costs and expenses FibroGen incurs (including Personnel Costs, the Fully Burdened Cost of Collaboration Compound or Product or comparator drug, concomitant drug, placebo or other materials used in any Clinical Trial or Nonclinical Studies, and all other out-of-pocket costs) for activities conducted by FibroGen (i) for the U.S. after the Development Sharing Period and (ii) for the RoW, in each case (i) and (ii) under the Development Plan within the applicable Development Budget (for the U.S.) or budget (for RoW) (subject to overages described in Section 3.4(b)) and according to the terms of Section 8.2, together with the reimbursement for supply of Collaboration Compound or Product in accordance with Article 6. For clarity, all Clinical Trials set out in the Initial Development Plan shall be deemed to be Development of the Product for the U.S.

(b) Overage. Notwithstanding the foregoing in Section 3.4(a), unless otherwise agreed by the JDC (subject to JSC approval to the extent set forth in Section 3.2(d)(ii)) or by the Parties, either before or after the applicable expense is incurred (which agreement shall not be unreasonably withheld for any budget overage outside the applicable Party’s reasonable

29.

control and reasonably incurred in the performance of the Development Plan), for any Calendar Quarter, each Party will be solely responsible for Development Costs it incurs in excess of [*] percent ([*]%) of the total amount allocated to such Party’s activities in such Calendar Quarter in the Development Budget, and for any Calendar Year, each Party will be solely responsible for Development Costs it incurs in excess of [*] percent ([*]%) of the total amount allocated to such Party’s activities in such Calendar Year in the Development Budget, provided that Development Costs incurred in excess of [*]% for the Calendar Quarter or [*]% for the Calendar Year, as applicable, of the amounts so budgeted shall also be reimbursed if the Parties determine in good faith that such Development Costs were reasonably incurred in the performance activities under the Development Plan and that such budget overage was caused by circumstances outside of such Party’s reasonable control.

3.5 Indications Outside the Field.

(a) Inclusion. If either Party desires to develop a particular Product for an indication outside the Field, it may propose such indication to the other Party in writing by providing the other Party with a high-level proposed development plan for such Product in such indication. Upon the other Party’s request within sixty (60) days after receipt of such development plan, the Parties shall meet to discuss such proposed indication and shall work together in good faith to generate and gather the necessary information to support such potential development and to prepare a detailed development plan. If the Parties agree on such plan, AstraZeneca shall have the right to include the proposed indication in the Field, solely with respect to the applicable Product, by written notice to FibroGen. If AstraZeneca exercises such right, such indication will be a “Designated Indication”, the Field will automatically be expanded to include the Designated Indication (without payment of any additional upfront fees, milestones or other consideration except those payments already provided for under this Agreement), the terms of this Agreement (including payment terms and diligence obligation) will apply to such indication and the JDC shall promptly prepare a development plan for such indication for review and approval by the JSC.

(b) Termination. The Field will automatically be amended to remove any Designated Indication upon the occurrence of any of the following events: (a) the permanent cessation (excluding, for example, suspension, termination or completion pending further review, consideration or development planning) of all Clinical Trials by both Parties with respect to such Product for such Designated Indication prior to Regulatory Approval in any country in the Territory in such Designated Indication, (b) the termination of all Regulatory Approvals for such Designated Indication in the Territory without either Party intending or considering to restore or replace any such Regulatory Approval, or (c) the decision of the JSC to permanently cease all Commercialization of such Product in such Designated Indication.

(c) Restriction. For clarity, Designated Indications are only those indications outside the Field that AstraZeneca agrees to include in this Agreement. Except for Designated Indications pursuant to this Agreement, FibroGen shall not Develop or Commercialize (directly or indirectly, by license, supply of Product or otherwise) any Product for any indication outside the Field in the Territory during the term of this Agreement.

30.

3.6 Additional Compounds.

(a) Added by FibroGen. At any time during the Term, FibroGen may upon written notice to AstraZeneca include any HIF Compound in the definition of Collaboration Compound (and Product). Effective upon such written notice, the identified HIF Compound shall be deemed a Collaboration Compound, provided that AstraZeneca shall not have any obligations with respect to such Collaboration Compound (or Product) under this Agreement unless and until AstraZeneca’s acceptance thereof through written notice to FibroGen.

(b) Added by Agreement.

(i) If AstraZeneca wishes to include additional HIF Compounds as Collaboration Compounds (and Products), it may make such a request to FibroGen. Upon receipt of such request, FibroGen shall make good faith and diligent efforts to present to the JSC for review all reasonably relevant data and other information (excluding chemical structures) Controlled by FibroGen that is related to those HIF Compounds that it reasonably believes offer substantial clinical benefit over then-current Collaboration Compounds from its library of HIF Compounds, including results from any Phase 2 Clinical Trial conducted in the Field. For clarity, the foregoing does not impose any obligation on FibroGen to identify or generate any additional HIF Compounds.

(ii) If AstraZeneca and FibroGen, through the JDC and JSC, agree upon a development program for any such HIF Compounds, then the Parties shall negotiate in good faith to agree on any additional consideration to be payable by AstraZeneca to FibroGen for inclusion of such additional HIF Compounds as Collaboration Compounds, and upon agreement, will amend this Agreement accordingly.

(c) Subject to Section 3.3 and to FibroGen’s obligations under the Astellas EU Agreement, FibroGen will use good faith in designating additional HIF Compounds as Collaboration Compounds pursuant to this Section 3.6, and shall not nominate additional HIF Compounds for Development in the [*] without approval of the JSC.

3.7 Veterinary Applications. Following the first approval of an NDA for a Product, the Parties may agree to develop the Product for a veterinary application. No additional consideration shall be payable by AstraZeneca to FibroGen with respect to such development. Upon agreement, the Parties shall enter into a separate agreement governing such applications or amend this Agreement accordingly prior to conducting any activities with respect to veterinary applications.

3.8 Research Collaboration. Upon FibroGen’s request, the Parties will discuss conducting a research program funded by AstraZeneca and directed toward franchise enhancement and lifecycle management for HIF Compounds or other topics that the Parties determine relevant to the Products and the Field. Upon agreement on the terms of such research program, the Parties will enter into a separate agreement or amend this Agreement accordingly.

31.

3.9 Diligence; Standards of Conduct.

(a) Each Party shall use Commercially Reasonable Efforts to Develop and obtain Regulatory Approval for the Products throughout the Territory (i) in the CKD Indications and (ii) in each [*], other indication in the Field and Designated Indication that [*] in the Development Plan. If at any time there is only one Collaboration Compound (either because no additional Collaboration Compounds have been developed or because development of all other Collaboration Compounds have been terminated), then the foregoing obligation shall be for one Product only.

(b) Each Party shall use Commercially Reasonable Efforts to carry out the tasks assigned to it under the Development Plan in a timely and effective manner. Each Party shall conduct its activities under the Development Plan in a good scientific manner and in compliance in all material respects with all applicable laws and regulations.

4.3 Adverse Event Reporting and Safety Data Exchange. At a time determined by the JSC, but in any event prior to the first to occur of (i) the commencement of any Clinical Trial to be conducted by AstraZeneca or (ii) the transfer of the first NDA in the U.S. to AstraZeneca, the Parties shall define and finalize the methods and procedures (based on and consistent where possible with those methods and procedures used by Astellas and FibroGen under the Astellas EU Agreement, unless otherwise mutually agreed) that the Parties shall employ with respect to Products to protect patient safety and promote the appropriate treatment of safety information of Products in a written pharmacovigilance agreement (the “Pharmacovigilance Agreement”). For clarity, the Pharmacovigilance Agreement shall include all relevant safety data regarding the Product, irrespective of territory or indication. These responsibilities shall include mutually acceptable guidelines and procedures for the receipt, investigation, recordation, communication, and exchange (as between the Parties) of adverse event reports, pregnancy reports, and any other information concerning the safety of any Product. Such guidelines and procedures shall be in accordance with, and enable the Parties to fulfill, local and national regulatory reporting obligations under applicable laws and regulations. Furthermore, such agreed procedure shall be consistent with GCP and relevant ICH guidelines, except where such guidelines may conflict with existing local regulatory reporting or safety reporting requirements, in which case the local reporting requirements shall prevail. FibroGen shall maintain a global safety database for the Products, the expenses for which will be included in Development Costs and reimbursed by AstraZeneca, to the extent not borne or reimbursed by Astellas. Each Party hereby agrees to comply with its respective obligations under such Pharmacovigilance Agreement and to cause its Affiliates and permitted sublicensees to comply with such obligations. If and to the extent necessary, the Pharmacovigilance Agreement shall be amended by the Parties, or shall be superseded, so that an appropriate commercial-stage pharmacovigilance agreement is in place in advance of the first NDA approval for a Product.

4.4 Product Withdrawals and Recalls. If any Regulatory Authority in or outside the Territory (a) threatens, initiates or advises any action to remove any Product from the market or (b) requires or advises FibroGen, AstraZeneca, or any of their respective Affiliates or Sublicensees to distribute a “Dear Doctor” letter or its equivalent regarding use of such Product, then FibroGen or AstraZeneca, as applicable, shall notify the other Party of such event within three (3) Business Days (or sooner if required by law) after such Party becomes aware of the action, threat, advice or requirement (as applicable). The JSC will discuss and attempt to agree upon whether to recall or

35.

withdraw a Product; provided, however, that if the Parties fail to agree within an appropriate time period, the Party who is the then-holder of the NDA for the Product at issue shall decide whether to recall or withdraw such Product. AstraZeneca shall be responsible, at its sole expense, for conducting any recalls or taking such other necessary remedial action in the Territory, except that FibroGen will be responsible for such expenses to the extent (i) resulting from the failure of any Product supplied by FibroGen to conform to the applicable specifications; or (ii) such recall results from an event outside the Territory and outside the territory licensed under the China Agreement.

ARTICLE 5

COMMERCIALIZATION

5.1 Overview. The Parties agree to collaborate with respect to the Commercialization of Products in the Field in the U.S. as provided in this Article 5 under the direction of the JCC, and pursuant to the U.S. Commercialization Plan applicable to each Product. AstraZeneca shall have the sole right and responsibility for Commercializing Products in the Field in the RoW under the direction of the JCC, in accordance with this Agreement and as provided in this Article 5. Prior to the JCC’s inception, all references to the JCC in this Article 5 and elsewhere in this Agreement will be deemed references to the JSC (which may delegate certain responsibilities to the Core JPT in accordance with Schedule G(b)).

5.2 U.S. Commercialization Plan. As further described in this Section 5.2, the comprehensive strategy for the Commercialization of each Product in the U.S. shall be described in a comprehensive plan that describes the pre-launch, launch and subsequent Commercialization of such Product in the U.S. (including without limitation the high level strategies regarding messaging, branding, pricing, advertising, planning, marketing, sales force training and allocation, and reimbursement/managed care), key tactics for implementing those activities and the relative responsibilities of the Parties (each such plan, a “U.S. Commercialization Plan”), and the associated budget for such activities that details the anticipated Commercialization Costs (each such budget, a “U.S. Commercialization Budget”).

(a) Promptly after the Effective Date, the JCC (or if not formed, the JSC) will determine the initial pre-commercial activities for which AstraZeneca will prepare an initial U.S. Commercialization Plan, which activities will include [*], but need not include all activities described in the first paragraph of this Section 5.2. Within ninety (90) days thereafter, AstraZeneca will present such plan to the JCC for review and approval. Within two (2) years after the Effective Date but in any event not later than two (2) years prior to the then currently anticipated NDA submission date, AstraZeneca will present to the JCC a U.S. Commercialization Plan covering all activities described in the first paragraph of this Section 5.2, for review and approval by the JCC, which plan will include the key prelaunch and launch activities, marketing and sales deployment required for the initial launch of the Product and associated budgets. The JCC shall review, revise and recommend for approval by the JSC such U.S. Commercialization Plan promptly after receipt thereof. If the JCC is not yet formed by any of the foregoing dates, the JSC will review, revise and approve the applicable U.S. Commercialization Plan.

(b) AstraZeneca will prepare a detailed U.S. Commercialization Plan and U.S. Commercialization Budget in preparation for U.S. launch of the Product for review and approval by the JCC no later than the submission of the first NDA for the Product, or at such other time determined by the JSC.

36.

(c) All U.S. Commercialization Plans and U.S. Commercialization Budgets with respect to Products in the U.S. and subsequent revisions thereto will contain such information as the JCC believes necessary for the successful Commercialization of such Product in the U.S., both pre- and post-launch, and shall generally conform to the level of detail utilized by AstraZeneca in preparation of its own product commercialization plans. On an annual basis (no later than October 31^st of the preceding Calendar Year), or more often as the Parties deem appropriate, the JCC shall prepare amendments to the then-current U.S. Commercialization Plan(s) and the corresponding U.S. Commercialization Budgets. In the event of any inconsistency between a U.S. Commercialization Plan and this Agreement, the terms of this Agreement shall prevail. Each Party shall conduct its activities under the U.S. Commercialization Plan in compliance in all material respects with all applicable laws and regulations.

5.3 RoW Commercialization Plans. AstraZeneca shall prepare Commercialization plans with respect to Products in the RoW on an annual basis, shall submit such plans to the JCC for review and approval, and shall respond in a timely fashion to any reasonable requests of FibroGen or the JCC with respect to such plans and Commercialization activities in the RoW.

5.4 Commercialization Costs. AstraZeneca shall be solely responsible for all Commercialization Costs incurred by it or by or on behalf of FibroGen under the Co-Commercialization Agreement and in the Commercialization of Products in the U.S. and RoW. AstraZeneca will reimburse FibroGen for such costs incurred by FibroGen, plus a markup of [*] to be applied to FibroGen’s [*] costs only, all pursuant to more detailed provisions to be included in the Co-Commercialization Agreement.

5.5 Sales and Distribution; Returns; Customer Support. AstraZeneca shall be solely responsible for handling all returns, recalls, order processing, invoicing and collection, booking of sales, distribution, and inventory and receivables for Products in the Territory. FibroGen shall not accept orders for Products or make sales for its own account or for AstraZeneca’s account, and if FibroGen receives any order for Products in the Territory, it shall refer such orders to AstraZeneca for acceptance or rejection. AstraZeneca shall be responsible for handling all returns of any Product. If Products are returned to FibroGen, FibroGen shall promptly ship such Products to AstraZeneca. FibroGen, if requested by AstraZeneca, shall advise the customer who made the return that the Products have been returned to AstraZeneca. AstraZeneca shall be responsible for providing customer support, handling medical queries, and responding to product and medical complaints relating to Products.

5.6 Commercialization Reports. Each Party shall keep the JCC fully informed regarding the progress and results of Commercialization activities for Products in the U.S. and RoW, including an annual review of results versus plans (as set forth in the U.S. Commercialization Plan(s)).

5.7 Samples. At a time determined by the JSC, the Parties will discuss in good faith whether, how, and under what circumstances the Parties would allow distribution of samples (i.e., Products provided free of or for a nominal charge) of Product for treatment of anemia in patients

37.

with chronic kidney disease not undergoing dialysis, or in other applicable indications outside of the CKD Indications. Neither Party will have the right to distribute Product samples without the prior written consent of the other Party, and, if such consent is granted, each Party will distribute such samples only according to the procedures and in the amounts agreed by the Parties in writing.

5.8 Commercialization Standards of Conduct.

(a) Execution of U.S. Commercialization Plan. Each Party shall use Commercially Reasonable Efforts to carry out the tasks assigned to it under the U.S. Commercialization Plan and the Co-Commercialization Agreement in a timely and effective manner and in compliance with all applicable laws and regulations.

(b) AstraZeneca Diligence Obligations. AstraZeneca shall use Commercially Reasonable Efforts to Commercialize each Product in each indication and country in the Territory for which Regulatory Approval is obtained, except for indications and countries for which FibroGen has independently obtained Regulatory Approval, without opt-in by AstraZeneca, under Section 3.3(b).

5.9 Subcontracts. Each Party may perform any of its obligations under the U.S. Commercialization Plan through one or more subcontractors or consultants, provided that (a) AstraZeneca will not subcontract any such activities without [*]; (b) such Party remains responsible for the work allocated to, and payment to, such subcontractors and consultants as it selects to the same extent it would if it had done such work itself; (c) the subcontractor undertakes in writing obligations of confidentiality and non-use regarding Product Information and Confidential Information, that are substantially the same as those undertaken by the Parties pursuant to Article 12 hereof, and (d) the subcontractor agrees in writing to assign all intellectual property developed in the course of performing any such work under the U.S. Commercialization Plan to the Party retaining such subcontractor. A Party may also subcontract work on terms other than those set forth in this Section 5.9, with the prior approval of the JCC. AstraZeneca will have [*] (subject to compliance with clauses (b) – (d) of this Section 5.9), except that AstraZeneca will be required to reasonably [*] Third Party subcontractors for such activity.

5.10 Co-Commercialization Agreement. Following submission of the first NDA for a Product or at such earlier time as AstraZeneca may request, the Parties will negotiate and enter into an agreement (the “Co-Commercialization Agreement”) governing the Parties’ conduct of activities for Commercializing the Product in the U.S. The Co-Commercialization Agreement will be consistent with the terms of this Article 5, Exhibit I, other terms agreed by the Parties, and other customary terms for such an agreement.

5.11 Regulatory Compliance.

(a) Each of FibroGen and AstraZeneca shall reasonably cooperate with the other Party in its efforts toward ensuring that all government reporting (including price and gift reporting), sales, marketing and promotional practices in respect of each Product meet the standards required by (A) applicable laws and regulations; (B) applicable guidelines concerning the advertising and promotion of prescription drug products, including without limitation the Office of the Inspector General’s (“OIG”) Compliance Guidance Program issued in 2003, the

The Parties shall cooperate in good faith to update their obligations under this Section 5.11(a) from time to time to reflect any changes in any of the foregoing (A) – (E) or to resolve any conflicts in any of the foregoing standards as applied to the Parties’ activities under this Agreement.

(b) Each Party shall be responsible for tracking and reporting transfers of value initiated and controlled by its employees and/or contractors pursuant to the requirements of Section 6002 (Transparency Reports and Reporting of Physician Ownership and Investment Interest) of the Affordable Care Act, commonly referred to as the “Sunshine Act”, and state marketing reporting laws. The value reported to the Centers for Medicare & Medicaid Services shall be the amount expended by the controlling Party, irrespective of the division of or reconciliation of expenses between the Parties.

(c) AstraZeneca shall provide its sales representatives appropriate training on proper marketing and sales techniques. Such training will include, among other topics, FDA requirements and other state and federal regulations and guidelines concerning the advertising of prescription drug products, the OIG Compliance Guidance Program, the AMA Guidelines on Gifts to Physicians, the PhRMA Code, and the ACCME Standards. If requested by FibroGen, AstraZeneca shall provide a written description of the training to FibroGen no less frequently than on an annual basis.

(d) Each of FibroGen and AstraZeneca shall reasonably cooperate with the other Party to provide the other Party access to any and all information, data and reports required by the other in order to comply with the relevant provisions of the Medicare Modernization Act and any other applicable laws and regulations, including without limitation reporting requirements, in a timely and appropriate manner. AstraZeneca shall ensure that its reporting to the Centers for Medicare and Medicaid Services and other federal and state healthcare programs related to the Products is true, complete and correct in all respects; provided however, that AstraZeneca shall not be held responsible for submitting erroneous reports if such deficiencies result from information provided by FibroGen which itself was not true, complete and correct.

(e) AstraZeneca shall, so far as practicable, provide to FibroGen in advance any submission containing any information provided by FibroGen pursuant to this Section 5.11 that AstraZeneca proposes to submit to any governmental entity. AstraZeneca further agrees to seek confidential treatment of any such information related to FibroGen that it submits to any governmental entity to the extent permitted under any applicable laws and regulations.

39.

(f) FibroGen and AstraZeneca shall confer with each other on a regular basis to discuss and compare their respective procedures and methodologies relating to each Party’s compliance to any applicable laws or regulations or fulfillment of any other obligation contained in this Section 5.11. In the event that the parties have different understandings or interpretations of this Section 5.11 or of the applicability of, or standards required by, any applicable laws or regulations, then the Parties shall confer and seek to reach common agreement on such matters.

(g) Each of AstraZeneca and (where applicable) FibroGen agrees that:

ARTICLE 6

MANUFACTURE AND SUPPLY

6.1 Purchase and Supply Commitment. AstraZeneca hereby appoints FibroGen as its exclusive supplier of Product (drug substance and drug product) for the Territory for use in accordance with the terms of this Agreement. AstraZeneca agrees to purchase, and FibroGen agrees to supply, all of AstraZeneca’s and its Affiliates’ and their respective Sublicensees’ requirements of Product (as bulk drug product and drug substance) for Development and Commercialization in the Territory under the terms of this Article 6. AstraZeneca shall have the exclusive right to perform (itself or through its Affiliates, Sublicensees or Distributors) and shall be solely responsible for final product labeling and secondary packaging for sale to end users in the Territory. To the extent that such labeling and packaging are relevant to FibroGen’s activities to seek and obtain Regulatory Approval for the Product, AstraZeneca will reasonably and timely cooperate with FibroGen, in a manner sufficient to enable FibroGen to receive Regulatory Approval and to provide materials and Information as requested by FibroGen. The right of FibroGen to manufacture on behalf of AstraZeneca contemplates that at a time to be determined by the JSC, and in any event before the point in time when [*] in any twelve (12) month period, AstraZeneca will have the right to select, or obligate FibroGen to select, a second supplier (which may be AstraZeneca itself), and FibroGen will have the obligation to complete activities to undertake technology transfer in order for such secondary source to establish and secure regulatory approval as a second source for drug substance for Product, which shall in any event not limit FibroGen’s right to continue to ensure that a source of Product be maintained in the U.S. in order to satisfy FibroGen’s obligations under the Astellas Agreements and the DFCI Agreement. For clarity, FibroGen shall have the right to manufacture Product outside the Territory to fulfill its supply obligations under this Agreement. For clarity, subject to the terms of this Agreement, FibroGen shall have the right to satisfy its obligations under this Article 6 through a Third Party contract manufacturer. In connection with FibroGen’s manufacture of Products for use under this Agreement, FibroGen shall have the right to manufacture in the Territory for supply of Products under the Astellas Agreements.

6.2 Development Supply. In connection with the supply of any Product for non-commercial use, FibroGen shall supply Product in compliance with applicable law and regulations, including GMP requirements, and in accordance with forecasts set forth in the Development Plan or, if not specified therein, the forecasts developed by the JDC as necessary for the conduct of Clinical Trials set forth in the Development Plan. FibroGen shall use Commercially Reasonable Efforts to meet any applicable timelines for supplying Product, subject to the reasonable lead time requirements of Third Party contract manufacturers. AstraZeneca will pay FibroGen’s Fully Burdened Cost for all Product supplied for Development, within forty-five (45) days after receipt of invoice therefor. All Products supplied for a country after Regulatory Approval in such country will be considered to be for commercial use, unless used specifically for Clinical Trials under the Development Plan. The terms of supply by FibroGen to AstraZeneca for use in any Clinical Trial conducted under the sponsorship of AstraZeneca or for other non-commercial use by or on behalf of AstraZeneca, are as set forth on Exhibit J.

6.3 Commercial Supply Agreement. At a time specified by AstraZeneca, but in any event in a reasonable period in advance of the anticipated launch date for the Product in the U.S.,

41.

the Parties will negotiate in good faith and enter into separate supply and quality agreements governing the commercial supply of Product (in bulk and primary packaged forms) from FibroGen to AstraZeneca (together, the “Supply and Quality Agreement”). The Supply and Quality Agreement will include the terms and conditions set forth on Exhibit K and contain such further customary and 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 as well as any other terms set forth in this Article 6. The initial Supply and Quality Agreement shall have a term of [*] years for the supply of drug substance, after which AstraZeneca would have the right to extend the term for an additional [*] years or to assume responsibility for drug substance manufacture upon agreement of terms mutually agreed by the Parties, including [*] in the form of drug substance. Under the Supply and Quality Agreement, the obligation to supply drug product shall have a term of five (5) years, which will automatically renew for succeeding five (5)-year terms and will include the price applicable pursuant to Section 6.5. 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.

6.4 Contract Manufacture Process. FibroGen is currently utilizing a contract manufacturer to fulfill its manufacturing timelines to complete drug product development in time for the expected commercial launch of the Product in the U.S. and under the Astellas Agreements. Notwithstanding the provisions of Section 6.3, upon AstraZeneca’s written request to FibroGen, not to be submitted earlier than six (6) months after the Effective Date, the Parties will discuss in good faith whether to select a separate contract manufacturer mutually acceptable to the Parties to be used for formulation and bulk drug product manufacture (using drug substance supplied by FibroGen) for commercial supply under this Agreement. The Parties shall discuss in good faith the transfer, including timely technology transfer, as soon as practicable following such mutual agreement. 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 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 reasonably necessary for a contract manufacturer to submit a bid with respect to such manufacture). AstraZeneca and its Affiliates shall provide a proposal on the same basis as the Third Party contract manufacturers. The Parties shall review and assess in good faith the bids submitted by the Third Party manufacturers and by AstraZeneca or its Affiliate and shall recommend to the JDC the bid that, on the whole, offers the most favorable terms for such manufacture based on a reasonable assessment of the relevant factors, including price, capital requirements, quality, capacity, capability to maintain continuity of supplies, considerations related to the supply of Product to Astellas and global supply of Product and overall timeline. FibroGen will enter into a supply and quality contract with the Third Party contract manufacturer, on terms consistent with the selected bid and otherwise reasonably acceptable to the Parties, or the responsibility to manufacture shall be transferred to AstraZeneca, as determined by the JDC. In the event FibroGen shall contract with AstraZeneca or its Affiliate in accordance with this Section 6.4, FibroGen shall – as soon as reasonably practicable after the completion of the selection process – provide the necessary technology transfer as well as all necessary assistance to obtain required regulatory approvals, all

42.

to enable AstraZeneca or its Affiliate to conduct the formulation and bulk drug product manufacture (using drug substance supplied by FibroGen) for supply of Product under this Agreement, and to Astellas under the Astellas Agreements. If AstraZeneca is not selected as the contract manufacturer, then at any time after the [*], at AstraZeneca’s request, the Parties shall [*]. For clarity, to the extent that the alternative formulation and drug product manufacture is transferred to such Third Party, FibroGen shall have the right to use such source of supply to satisfy FibroGen’s obligations under the Astellas Agreements.

6.5 Transfer Price.

(a) FibroGen will supply to AstraZeneca (or its designated Affiliate or Sublicensee) Product for commercial use as drug product at a transfer price equal to [*] during the Calendar Year in which such Product is delivered. Notwithstanding the foregoing, in the event that the Parties agree that AstraZeneca shall supply drug product and FibroGen shall only supply drug substance, the transfer price for such drug substance shall be [*] during the Calendar Year in which such Product is delivered.

(i) If FibroGen supplies Product as drug product, then not less than thirty (30) days prior to the beginning of each Calendar Year during which FibroGen will be supplying product (each a “Delivery Year”), the Parties will calculate a preliminary transfer price per unit (the “Preliminary Price Per Unit”), which shall be equal to [*] multiplied by the fraction (A)/(B), where (A) shall be the estimated [*] for such Delivery Year and (B) shall be the estimated [*] in the Territory during such Delivery Year (all estimations to be made by the Parties in good faith). FibroGen will invoice AstraZeneca upon delivery of each shipment of product at the Preliminary Price Per Unit and AstraZeneca will pay for such product at such price within forty-five (45) days after its receipt of such invoice. Within forty-five (45) days following the end of each Delivery Year, the Parties will calculate the definitive transfer price per unit (“Definitive Price Per Unit”) for such year, which shall be equal to [*] multiplied by the fraction (A)/(B), where (A) shall be the actual [*] made during the Delivery Year and (B) shall be the actual [*] in the Territory during such Delivery Year (excluding [*]). If the transfer price for the total volume of product actually delivered by FibroGen during the Delivery Year at the Definitive Price Per Unit (the “Total Definitive Price”) exceeds the transfer price for such volume based on the Preliminary Price Per Unit (the “Total Preliminary Price”), then AstraZeneca shall pay the difference to FibroGen within forty-five (45) days after its receipt of an invoice from FibroGen for such amount. If the Total Preliminary Price exceeds the Total Definitive Price, FibroGen shall issue a credit note to AstraZeneca for the difference. AstraZeneca shall be entitled to set off the amount due under the credit note against any subsequent payments owed by AstraZeneca to FibroGen under this Agreement (or, in the absence of any such subsequent payments, such credit note shall be settled by FibroGen within forty-five (45) days after its receipt thereof).

(ii) If FibroGen supplies Product as drug substance, then the Parties shall calculate the price for Product according to a process similar to that described in clause (i) above, except that the multiplier shall be [*] during the Delivery Year.

(b) Potential Cost Reductions. At either Party’s request during the Term, the Parties shall discuss and explore potential means of collaborating to reduce the overall costs of manufacture and supply of Products as drug substance or bulk drug product under this Agreement,

43.

with the understanding that the Parties shall share the financial benefits of any such cost reductions achieved in a reasonable manner taking into account to what extent each Party has contributed to such cost reductions.

(c) Adjustment for Generic Entry. If at any time FibroGen’s net margin percentage on any Product supplied to AstraZeneca falls below [*] after a Generic Product is sold in any country in the Territory, FibroGen shall have the right to renegotiate the manufacturing and supply payment terms under the Supply and Quality Agreement. Upon FibroGen’s request, the Parties shall renegotiate reasonable terms in good faith, taking into account also the overall profitability of such Product to AstraZeneca.

The license granted by FibroGen to AstraZeneca in Section 7.1 may be sublicensed by AstraZeneca: (i) to an Affiliate of AstraZeneca without any requirement of consent, provided that such sublicense to an Affiliate of AstraZeneca shall immediately terminate if and when such party ceases to be an Affiliate of AstraZeneca, or (ii) where such sublicense is made to enable a Third Party to provide contract research or development services or contract manufacturing services for AstraZeneca, its Affiliates or Sublicensees, without such Third Party being granted the right to distribute, market or sell a Product, to such Third Party without any requirement of consent, but upon written notice to FibroGen and subject to Sections 3.12 and 5.9, and no sooner than twelve (12) days after such notice, or (iii) otherwise (i.e. other than pursuant to (i) or (ii) above) only with the prior written consent of FibroGen, not to be unreasonably withheld, and no sooner than twelve (12) days after such consent is obtained. It will not be unreasonable for FibroGen to withhold its consent to a sublicense pursuant to subsection (iii) above to (1) any entity that [*] or (2) any company engaged in the sales of tobacco or tobacco-related products. AstraZeneca shall be liable to FibroGen for the acts or omissions of its Sublicensees, and any breach of an applicable provision of this Agreement by a Sublicensee shall be deemed to be a breach by AstraZeneca.

(b) Sublicense Agreements. AstraZeneca shall, in each agreement under which it grants a sublicense under a license set forth in Section 7.1 (each, a “Sublicense Agreement”), require the Sublicensee to (A) comply with the obligations in Section 7.8 (as applied to such Sublicensee and its Affiliates) and (B) provide the following to FibroGen if this Agreement terminates and to AstraZeneca if only such Sublicense Agreement terminates: (i) the assignment and transfer of ownership and possession of all Regulatory Materials and Regulatory Approvals held or possessed by such Sublicensee (which assignment could also be directly to AstraZeneca prior to any such termination), and (ii) the assignment of, or a freely sublicensable exclusive license to, all intellectual property Controlled by such Sublicensee that covers or embodies a Product or Collaboration Compound or its respective use, manufacture, sale, or importation and was created by or on behalf of such Sublicensee during the exercise of its rights or fulfillment of its obligations pursuant to such Sublicense Agreement. Each Sublicense Agreement shall be subject to the applicable terms and conditions of this Agreement, the DFCI Agreement and any Third Party licenses sublicensed to the Sublicensee. AstraZeneca shall include a copy of the DFCI Agreement in all Sublicense Agreements.

Annually, AstraZeneca shall forward to FibroGen a copy of the reports received by AstraZeneca from its Sublicensees during the preceding twelve (12) month period under each Sublicense Agreement as shall be pertinent to (i) the Sublicensee’s operations under each Sublicense Agreement and (ii) a royalty accounting under the Sublicense Agreement, in each case solely to the extent relevant to FibroGen’s rights under this Agreement or (to the extent different, as notified by FibroGen to AstraZeneca) DFCI’s rights under the DFCI Agreement. FibroGen shall have the right to provide each such report to DFCI. FibroGen shall require DFCI to comply with confidentiality and non-use obligations in respect of information disclosed to DFCI in accordance with this Section 7.3(b), which obligations shall be substantially the same as those undertaken by the Parties pursuant to Article 12.

45.

(c) Distributorships. AstraZeneca shall have the right, in its sole discretion, to appoint its Affiliates, and AstraZeneca, its Affiliates and its Sublicensees shall have the right, in their sole discretion, to appoint any other person or entity, in the Territory, to distribute, market and sell the Products, with or without packaging rights. In circumstances where such appointed person or entity purchases its requirements of Products from AstraZeneca, its Affiliates or its Sublicensees, but does not otherwise make any royalty or other payment to AstraZeneca, its Affiliates or its Sublicensees with respect to intellectual property rights, and where such person is not an Affiliate of AstraZeneca, then that person or entity shall be a “Distributor” for purposes of this Agreement. The term “packaging rights” in this Section 7.3(c) shall mean the right for the Distributor to package Products supplied in unpackaged bulk form into individual ready-for-sale packs.

(d) Co-Promotion. Subject to Section 5.9, AstraZeneca and its Affiliates shall have the right, in their sole discretion, to co-promote the Products with any other person or entity, or to appoint one or more Third Parties to promote the Products without AstraZeneca in all or any part of the Territory, provided however that the foregoing shall not adversely impact FibroGen’s right to co-promote the Product as described under this Agreement.

7.4 FibroGen’s Activities.

(a) Covenant by FibroGen. Except pursuant to this Agreement or the China Agreement, FibroGen and its Affiliates shall not, and shall not license or authorize any Third Party to, directly or indirectly,

FINANCIALS

8.1 License Fees. AstraZeneca shall pay to FibroGen each of the following non-refundable, non-creditable license fees on or before the applicable date set forth below; provided that with respect to payment 1, FibroGen shall provide an invoice on or before the Effective Date, and with respect to payments 2, 3 and 4, FibroGen shall provide an invoice at least forty-five (45) days before each applicable due date:


Number	Due Date	Payment
1	15^th Business Day after the Effective Date	$70 million
2	June 30, 2014	$110 million
3	June 30, 2015	[*]
4	June 30, 2016	[*]

If this Agreement is terminated prior to the due date of payment 2 or 3, then each such payment shall remain due and payable despite such termination. If this Agreement is terminated prior to the due date of payment 4, then payment 4 will remain due and payable despite such termination; [*].

8.2 Development and Commercialization Cost Reimbursement.

(a) Prior to First NDA Approval during Development Sharing Period. The following procedure in this subsection (a) will apply prior to the first NDA approval for a Product and during the Development Sharing Period.

(i) On or before the Effective Date, FibroGen will submit an invoice to AstraZeneca for an amount of [*] in respect of certain Development Costs incurred by FibroGen under the Development Plan prior to the Effective Date. AstraZeneca shall pay such invoice within fifteen (15) Business Days of receipt of invoice.

(ii) Within twenty (20) days if reasonably possible for AstraZeneca using reasonable endeavors to meet such timeline and in no event later than twenty five (25) days after the end of each Calendar Quarter during the Development Sharing Period, and within fifteen (15) days if reasonably possible for FibroGen using reasonable endeavors to meet such timeline and in no event later than twenty (20) days after the end of each Calendar Quarter, the Party shall provide the other Party with a statement setting forth (A) the actual Development Costs incurred by such Party in such Calendar Quarter, (B) the Development Costs budgeted for activities conducted by such Party in such Calendar Quarter under the Development Plan, (C) the amount (if any) by which the actual costs differed from the budgeted costs, subject to the provisions on budget overages in Section 3.4(b), (the “Excess Spend”), (D) the amount carried over from the previous Calendar Quarters for which the Development Costs incurred by AstraZeneca were greater than the Development Costs incurred by FibroGen. As soon as practicable, and not later than within thirty two (32) days of the end of the Calendar Quarter, the Parties shall discuss and resolve any issues with respect to such statements and shall use best efforts to agree the amount owed from one Party to the other for Development Costs in such Calendar Quarter, so that each Party bears fifty percent (50%) of the Development Costs incurred (subject to Section 3.4(b)), provided, however that each Party shall generate any questions and respond to any inquiries regarding the invoices as promptly as reasonably possible following receipt, including within forty-eight (48) hours for response to ordinary inquiries. Following the reconciliation process for the applicable Calendar Quarter, and not later than thirty two (32) days of the end of the Calendar

50.

Quarter, each of FibroGen and AstraZeneca shall provide an invoice to the other Party reflecting fifty percent (50%) of their respective Development Costs incurred. Within forty five (45) days after its receipt of such invoice from FibroGen, if the amount invoiced by FibroGen to AstraZeneca is greater than the amount invoiced by AstraZeneca to FibroGen, then AstraZeneca shall pay FibroGen an amount equal the difference between the invoices, subject to the offset of outstanding Development Costs as detailed below in this Section 8.2(a)(ii). If during the Development Sharing Period and following the quarterly process set out above, FibroGen owes a payment to AstraZeneca, then no payment will be made by FibroGen, to AstraZeneca. Instead such amount, in aggregate with any other such amounts, will be carried forward by AstraZeneca and set off against any subsequent Development Cost payments owed by AstraZeneca to FibroGen under this Section 8.2. For clarity, Development Costs advanced or paid under this Section 8.2(a)(ii) do not include amounts incurred prior to August 1, 2013.

(b) Prior to First NDA Approval after the Development Sharing Period. The following procedure in this subsection (b) will apply prior to the first NDA approval for a Product and after the Development Sharing Period.

(i) No earlier than forty-five (45) days prior to the beginning of each Calendar Quarter after the Development Sharing Period, FibroGen shall submit to AstraZeneca an invoice for the Development Costs budgeted to be incurred by FibroGen to conduct its activities under the Development Plan in such Calendar Quarter, as adjusted for the Cost Difference as set forth in 8.2(b)(ii) below. AstraZeneca shall pay each such invoice within forty-five (45) days after the invoice date, subject to the offset of Development Cost provisions in Section 8.2(a).

(ii) No later than twenty (20)) days after the end of each Calendar Quarter after the Development Sharing Period, FibroGen shall send to AstraZeneca a statement setting forth (i) the actual Development Costs incurred by FibroGen in such Calendar Quarter, (ii) the Development Costs budgeted for activities conducted by FibroGen in such Calendar Quarter in the Development Plan, (iii) the amount (if any) by which the actual costs differed from the budgeted costs and (iv) the difference between the amount advanced by AstraZeneca under this Section 8.2(b) and the Development Costs actually incurred, to the extent below [*] percent ([*]%) of the budgeted amount (the “Cost Difference”). FibroGen shall adjust the invoice to be submitted to AstraZeneca under 8.2(b)(i) for the subsequent Calendar Quarter to account for the Cost Difference. Not later than within thirty two (32) days of the end of the Calendar Quarter, the Parties shall discuss and resolve any issues with respect to such statement and shall use best effort to agree the amount payable thereunder. If any items not material to FibroGen’s financial statements remain outstanding at the end of the reconciliation and resolution process, the parties shall continue to work toward resolution by the end of following calendar quarter. Notwithstanding anything else set forth herein, if all amounts invoiced by FibroGen and settled under Section 8.2(a) exceed fifty per cent (50%) of the difference between the Development Costs incurred by FibroGen and the Development Costs incurred by AstraZeneca during the Development Sharing Period (subject to the provisions on budget overages in Section 3.4(b)), then any such excess may be credited by AstraZeneca against any subsequent Development Costs payments owed by AstraZeneca to FibroGen under this Section 8.2(b) and Section 8.2(c), or, in the event that the Development Costs incurred by FibroGen are no longer being incurred under this Agreement and are insufficient to make up such excess, such excess may be credited against any other payments owed by AstraZeneca to FibroGen under this Agreement, until fully used.

51.

(c) Adjustment in Payment Schedule. At any time after January 1, 2015 and prior to the time at which ninety percent (90%) of the targeted enrollment in any CKD Indication Clinical Trials (conducted by FibroGen and for which FibroGen will be incurring Development Costs) has been achieved (the “Increased Advance Period”), upon request of FibroGen, the Parties shall discuss in good faith the upcoming spending plans for the Development Budget in which FibroGen reasonably anticipates that significant cost variances, such as those associated with patient enrollment rates or other reasonably unforeseen causes, may occur with respect to such CKD Indication Clinical Trials during the next Development Budget year and thereafter. The Parties shall agree upon the timing of the implementation of a further advance in any Calendar Quarter in an upcoming period during the Increased Advance Period: If FibroGen reasonably determines that anticipated spending in respect of such CKD Indication Clinical Trials such as enrollment rate is proceeding in a manner that the Development Costs for which advances have been received in a Calendar Quarter under Section 8.2(a) or (b) will likely be exceeded, then FibroGen shall notify the JSC of the basis for such anticipated overage and if such overage is anticipated to exceed by [*] percent ([*]%) or more such budgeted amount, then FibroGen may invoice AstraZeneca prior to the end of the Calendar Quarter an amount it reasonably believes is necessary to cover such overage. AstraZeneca shall pay such amount within forty-five (45) days of invoice and any such amounts advanced under such invoice under this Section 8.2(c) shall be deducted from the subsequent payment under Section 8.2(a), (b) or (d).

(d) Following First NDA Approval. The following procedure in this subsection (d) will apply after the first NDA approval for a Product, unless otherwise agreed by the JDC. Within thirty (30) days after the end of each Calendar Quarter in which FibroGen conducts activities under the Development Plan, FibroGen shall send to AstraZeneca an invoice for all Development Costs incurred by FibroGen in such Calendar Quarter, up to an amount equal to [*] percent ([*]%) of the budgeted amount for the applicable activities. AstraZeneca shall pay each such invoice within forty-five (45) days after receipt thereof.

(e) Annual Reconciliation. Within thirty (30) days after the end of each Calendar Year in which either Party conducts activities under the Development Plan, such Party shall send to the other Party a statement setting forth the Development Costs actually incurred by such Party and the budgeted amounts for all activities conducted by such Party under the Development Plan during such Calendar Year; provided that if no part of such Calendar Year was during the Development Sharing Period, or if only FibroGen is conducting Development activities, only FibroGen shall be required to provide such statement. FibroGen’s statement will also include the Development Costs incurred by FibroGen and actually reimbursed by Astellas for such Calendar Year. If during the Development Sharing Period, such actual amount exceeds the budgeted amount (or amount otherwise approved by the JSC) by more than [*] percent ([*]%) of the budgeted amount, then fifty percent (50%) of the excess (i.e., above [*] percent ([*]%)) will be credited against or added to (depending on which Party incurred the excess) the subsequent payment from AstraZeneca to FibroGen under this Section 8.2. After the Development Sharing Period, if such actual amount incurred by FibroGen exceeds the budgeted amount (or amount otherwise approved by the JSC) by more than [*] percent ([*]%) of the budgeted amount, the excess (i.e., above [*] percent ([*]%)) will be credited against the subsequent payment from AstraZeneca to FibroGen under this Section 8.2.

52.

(f) RoW Activities. Within thirty (30) days after the end of each Calendar Quarter in which FibroGen conducts activities under the Development Plan for the RoW, FibroGen shall send to AstraZeneca an invoice for all costs incurred by FibroGen in such Calendar Quarter for such activities, including Personnel Costs, the Fully Burdened Cost of Collaboration Compound or Product or comparator drug, concomitant drug, placebo or other materials used in any Clinical Trial or Nonclinical Studies, and all other out-of-pocket costs. AstraZeneca shall pay each such invoice within forty-five (45) days after receipt thereof.

(g) Commercialization Cost. Within thirty (30) days after the end of each Calendar Quarter in which FibroGen conducts activities under the U.S. Commercialization Plan, FibroGen shall send to AstraZeneca an invoice for all Commercialization Costs incurred by FibroGen in such Calendar Quarter. AstraZeneca shall pay each such invoice within forty-five (45) days after receipt thereof.

(ii) Each milestone payment in Section 8.3(a) shall be paid only once, without regard to whether two or more Products ultimately achieve any such milestone event. For the purposes of milestone events no. 5, 6 and 7 in Section 8.3(a), the Parties agree that the [*] shall be regarded as one and the same indication and thus not constitute [*].

(iii) The foregoing milestone events do not include events achieved by the Product for indications independently developed by FibroGen pursuant to Section 3.3(b) for which AstraZeneca does not opt in.

(c) Notice; Payment. The applicable Party shall notify the other Party upon achievement of each milestone in Section 8.3(a). AstraZeneca shall pay to FibroGen the amounts set forth in Section 8.3(a) within forty-five (45) days after receipt by AstraZeneca of an invoice from FibroGen for the relevant amount, following the achievement of the applicable milestone event by AstraZeneca, its Affiliate or a Sublicensee (or, if applicable, by FibroGen).

Each such payment shall be made by wire transfer of immediately available funds into an account designated by FibroGen. Each such payment is nonrefundable and non-creditable against any other payments due hereunder.

8.6 Royalties

(a) Royalty Rates. AstraZeneca shall pay to FibroGen non-refundable, non-creditable royalties on the amount of aggregate Annual Net Sales of each Product in the Territory as calculated by multiplying the applicable royalty rates set forth below by the corresponding amount of incremental aggregate Annual Net Sales in the Territory of such Product in such Calendar Year. For clarity, royalties are not due on sales of Products by FibroGen solely in indications independently developed by FibroGen pursuant to Section 3.3(b) for which AstraZeneca does not opt in.


Aggregate Annual Net Sales (Per Product)		Royalty Rate
Portion less than $[*]		[*]%
Portion greater than or equal to $[*]		[*]%

56.

By way of example, if the aggregate Annual Net Sales of a Product in the Territory in a particular Calendar Year is two billion five hundred million Dollars ($2,500,000,000), the amount of royalties payable hereunder shall be as follows:

$ [*]

[*]

(b) Sales Subject to Royalties. Sales between AstraZeneca, its Affiliates and Sublicensees shall not be subject to royalties hereunder unless the purchaser is an end user. Royalties shall be calculated on AstraZeneca’s, its Affiliates’ and Sublicensees’ sales of the Products to a Third Party, including Distributors (but excluding for the avoidance of doubt Sublicensees). Royalties shall be payable only once for any individual S.K.U. of a Product. For the purpose of determining Net Sales, the Product shall be deemed to be sold when invoiced and a “sale” shall not include, and no royalties shall be payable on, transfers by AstraZeneca, its Affiliates or Sublicensees of reasonable quantities of clinical trial materials, or other transfers or dispositions of reasonable quantities of Products for charitable, promotional, nonclinical, clinical, manufacturing, testing or qualification, regulatory or governmental purposes in compliance with this Agreement (it being understood and agreed that neither Party shall have the right to distribute the Product as samples except pursuant to Section 5.7).

(c) Generic Competition. If, in any country in the Territory, the Net Sales of any Product in any rolling four Calendar Quarter period following the first sale of a Generic Product to such Product in such country is less than [*] of the Net Sales for such Product in such country in the immediately preceding four Calendar Quarter period, then the royalty rate for such Product in such country shall be reduced to [*] that would otherwise have been applicable under Section 8.6(a) for Net Sales of such Product in such country. For clarity, if the Generic Product is barred or withdrawn from sale in such country and the Net Sales in such country in any rolling four Calendar Quarter period is greater than [*] of the value for the rolling four quarter period prior to the first sale of a Generic Product, then the foregoing reduction shall no longer apply effective as of the Calendar Quarter in which the Generic Product is barred or withdrawn from sale. The calculation of the royalty reduction under this Section 8.6(c) shall be conducted separately for each Product in each country. By way of example, if during the first Calendar Quarter of a particular Calendar Year in which the foregoing reduction applies, the Net Sales in such Calendar Quarter in a country in which the foregoing reduction applies are one billion five hundred million Dollars ($1,500,000,000), and the Net Sales in such Calendar Quarter in a country in which the foregoing royalty reduction does not apply are one billion Dollars ($1,000,000,000), the following shall apply with respect to the royalty payment owed for such Calendar Quarter: The royalty payment without regard to the reduced rate would be [*].

(d) Compulsory Licenses. If a court or a governmental agency of competent jurisdiction requires AstraZeneca or its Affiliate or Sublicensee to grant a compulsory license to a Third Party and if as a result of the compulsory license the Net Sales of such Product in any rolling four Calendar Quarter period following the first grant of such compulsory license in such country is less than [*] of the Net Sales for such Product in such country in the immediately preceding four

57.

Calendar Quarter period, then the royalty rate for such Product in such country shall be reduced to [*] of the royalty rates (in each tier) that would otherwise have been applicable under Section 8.6(a) for Net Sales of such Product in such country. For clarity, to the extent that the compulsory licenses in the relevant country are duly terminated or expire in such country and the Net Sales in such country in any rolling four Calendar Quarter period is greater than [*] of the value for the rolling four quarter period prior to the first grant of the compulsory license in such country, then the foregoing reduction shall no longer apply effective as of the Calendar Quarter in which the compulsory license is terminated or expires. The calculation of the royalty reduction under this Section 8.6(e) shall be conducted separately for each Product in each country.

(e) Order of Royalty Reduction and Royalty Floor. Any reductions set forth in Sections 8.6(c), 8.6(d) and 8.8(c) shall be applied in the order in which the event triggering such reduction occurs, provided that in no event shall, due to the cumulative reductions set out in Sections 8.6(c) and 8.6(d), the royalty that would otherwise have been payable to FibroGen under this Section 8.6 in a particular Calendar Quarter be reduced below [*]) of the royalty set forth in Section 8.6(a).

(f) Royalty Term. AstraZeneca’s obligation to pay royalties due under this Section 8.6 with respect to a particular Product in each country in the Territory will commence upon the First Commercial Sale of such Product in such country and will be payable for so long as such Product is sold in such country by AstraZeneca or its Affiliate or Sublicensee.

(g) Royalty Payments and Reports. All amounts payable to FibroGen pursuant to this Section 8.6 shall be paid in Dollars within forty-five (45) days after the end of each Calendar Quarter with respect to Net Sales in such Calendar Quarter. Each payment of royalties due to FibroGen shall be accompanied by a statement, on a country-by-country basis, of the amount of gross sales of Products in the Territory during the applicable Calendar Quarter, a calculation of Net Sales in the Territory showing the aggregate deductions from gross sales provided for in the definition of Net Sales during such Calendar Quarter, and a calculation of the amount of royalty payment due on such sales for such Calendar Quarter. For the avoidance of doubt, FibroGen acknowledges and agrees that each statement provided by AstraZeneca under this Section 8.6(g) shall constitute Confidential Information of AstraZeneca and FibroGen shall comply with its confidentiality and non-use obligations in respect of such statements as set forth in Article 12.

(h) Clarification. AstraZeneca acknowledges that it will continue to enjoy substantial benefit from its license under, and the transfer to AstraZeneca of certain elements of, the FibroGen Technology pursuant to this Agreement, as well as from AstraZeneca’s own development of inventions derived from the practice of such license and AstraZeneca’s use of such FibroGen Technology, even after the expiration of all FibroGen Patents claiming the Product in a particular country in which Products are sold. In addition, AstraZeneca acknowledges that the application of a uniform royalty structure during the sale of Products is more convenient to the Parties, facilitates payments, and reduces accounting burdens on the Parties, as compared with a payment structure dependent on the expiration of FibroGen Patents.

8.7 FibroGen IPO. AstraZeneca shall make a one-time, non-refundable, non-creditable payment of [*] to FibroGen upon a FibroGen IPO; provided that (a) if such IPO has

58.

not occurred prior to December 1, 2015, AstraZeneca will make such payment on December 15, 2015, and (b) if the Parties agree upon terms (and FibroGen undertakes, upon AstraZeneca’s request, to negotiate such terms in good faith), including a lock-up and standstill agreement (subject to maximum ownership of [*]%), then in lieu of such payment, AstraZeneca will make a [*] equity investment in FibroGen at the initial public offering price simultaneous with the closing of a FibroGen IPO.

8.8 Third Party Intellectual Property.

(a) DFCI Agreement. FibroGen shall be solely responsible for all payments to DFCI under the DFCI Agreement.

(b) Right to Obtain License. If either Party desires to obtain a license under any Third Party’s intellectual property in connection with the Development and Commercialization of Products, such Party will notify the other Party. FibroGen will have the first right (but not the obligation) to obtain such license. If FibroGen elects not to obtain such license, or is unsuccessful in doing so, then AstraZeneca will have the right (but not the obligation) to negotiate and obtain such license at its sole discretion and expense (but subject to Section 8.8(c)). The negotiating Party will obtain such license, with the right to sublicense, in order to permit AstraZeneca to exercise its rights and to perform its obligations under this Agreement. Subject to the foregoing, the terms and conditions involved in obtaining such license shall be determined at such negotiating Party’s sole discretion.

(c) AstraZeneca Obtains License. In the event AstraZeneca obtains a license under any Third Party patents that claim the composition of matter, formulation (to the extent AstraZeneca is performing any formulation activities, which activities it may perform only with FibroGen’s prior written consent), method of treatment or other use of a Collaboration Compound or Product, AstraZeneca shall provide to FibroGen a copy thereof and shall have the right to offset, against royalties payable to FibroGen under Section 8.6 for the applicable Product, [*] actually paid by AstraZeneca to such Third Party under such license for the sale of the applicable Product in the applicable country and Calendar Quarter; provided that the royalties payable to FibroGen for any Product in any Calendar Quarter under Section 8.6 may not be reduced by more than [*] of those otherwise due to FibroGen under Section 8.6(a) in any Calendar Quarter for such Product as a result of such offset and other reductions under Section 8.6. Except as provided above in this subsection (c), AstraZeneca will be solely responsible for all amounts owed by AstraZeneca or its Affiliates to Third Parties under a license to intellectual property on account of AstraZeneca’s or its Affiliates’ manufacture, use, sale, offer for sale, or import of Products.

(d) FibroGen Obtains License. Except as provided in subsection (a) above, the FibroGen Technology licensed to AstraZeneca in this Agreement will include patents, patent applications and Information licensed to FibroGen by a Third Party if (i) AstraZeneca assumes [*] of all payment obligations under such license agreement to the extent arising out of the use, Development or manufacture of any Product or Commercialization of any Product by or on behalf of AstraZeneca in the Territory, as well as all other obligations of such license agreement that are applicable to AstraZeneca, and (ii) AstraZeneca acknowledges in writing that its sublicense under such license agreement is subject to the terms and conditions of such license agreement. If any such payments are not allocated among countries, the Parties shall reasonably allocate such payments to within and outside the Territory in good faith.

59.

8.9 Taxes.

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the collaborative efforts of the Parties under this Agreement.

(b) Withholding Tax. The Party making payments under this Agreement (the “Payor”) to the other Party (the “Payee”) shall deduct or withhold from the payments any Taxes that it is required by applicable law to deduct or withhold. The Payee shall provide the Payor any tax forms or appropriate governmental authorization that may be reasonably necessary in order for Payor to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. The Payee shall use reasonable efforts to provide any such tax forms to the Payor at least thirty (30) days prior to the due date for any payment for which the Payee desires that Payor apply a reduced withholding rate and in any event at least fifteen (15) days prior to the time the applicable payment is due. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable laws and regulations, of withholding taxes, Indirect Taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or Indirect Taxes.

(c) Payment of Tax. To the extent the Payor is required by applicable law or regulations to deduct and withhold taxes on any payment to the Payee, the Payor shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the Payee an official tax certificate or other evidence of such withholding sufficient to enable the Payee to claim such payment of taxes.

(d) Indirect Tax. All payments to be made by one Party to another Party, pursuant to the terms of this Agreement, are stated exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of such payments, the Party making shall payment shall pay such Indirect Taxes at the applicable rate following the receipt where applicable of an Indirect Taxes invoice in the appropriate form issued. Each Party shall issue valid invoices for all amounts payable under this Agreement consistent with all applicable laws and irrespective of whether such amounts may be netted for settlement purposes. The Parties shall cooperate in accordance with applicable law to minimize Indirect Taxes.

(e) Imports. For the avoidance of doubt, the Parties acknowledge and agree that none of the upfront payments, milestone payments or royalties payable under this Agreement are related to the license (or right) to import or any import of Products. The Parties shall cooperate to ensure that the Party responsible for shipping values Product in accordance with applicable laws and maximizes the full benefits of available duty free or savings programs and minimizes where permissible any such duties and any related import taxes that are not reclaimable from the relevant authorities. The receiving Party shall be responsible for any import clearance, including payment of any import duties and similar charges, in connection with any Products transferred to such Party under this Agreement.

60.

8.10 Blocked Currency. In each country where the local currency is blocked and cannot be removed from the country, royalties accrued on Net Sales in that country shall be paid to FibroGen in the equivalent amount in Dollars.

8.11 Foreign Exchange. Conversion of sales or expenses recorded in local currencies to Dollars will be performed in a manner consistent with each Party’s normal practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates.

8.12 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at a rate equal to the U.S. Prime Rate for the date payment was due as reported by the Wall Street Journal.

8.13 Financial Records; Audits.

(a) Records. Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party to confirm the accuracy of the amount to be reimbursed, pursuant to Section 8.2, with respect to Development Costs or Commercialization Costs or other amounts to be reimbursed or shared hereunder incurred or generated (as applicable) by such Party, achievement of sales milestones, royalty payments and other compensation payable under this Agreement. Each Party shall keep or cause its Affiliates to keep such records for a period of the later of (a) six (6) years after the end of the period to which such books, records and accounts pertain and (b) the expiration of the applicable tax statute of limitations (or any extensions thereof), or for such longer period as may be required by applicable law. Each Party shall maintain such records at its principal place of business or the principal place of business of the appropriate division of such Party to which this Agreement relates.

(b) Procedure. Upon reasonable prior notice, such records shall be open during regular business hours for a period of three (3) years from the creation of individual records, in each case, for examination at the auditing Party’s expense, and not more often than once each Calendar Year, by an independent certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party (or in the case of audits of AstraZeneca, by DFCI under the terms of Section 4.2.2 of the DFCI Agreement) for the sole purpose of verifying for the auditing Party the accuracy of the financial reports or sales milestone notices furnished by the audited Party pursuant to this Agreement or of any payments made, or required to be made, by or to the audited Party to the other pursuant to this Agreement. Any such auditor shall not disclose the audited Party’s Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments due by the audited Party under this Agreement. Any amounts shown to be owed but unpaid, or overpaid and in need of reimbursement, shall be paid or refunded (as the case may be) within thirty (30) days after the accountant’s report, plus interest (as set forth in Section 8.12) from the original due date (unless challenged in good faith by the audited Party in which case any dispute with respect thereto shall be resolved in accordance with Article 14). The auditing Party shall bear the full cost of such audit unless such audit reveals an overcharge or underpayment by the audited Party that resulted from a discrepancy in a report that the audited Party provided to the other Party during the applicable audit period, which underpayment or overcharge was more than five percent (5%) of the amount set forth in such report, in which case the audited Party shall bear the full cost of such audit.

61.

(c) Audit Dispute. In the event of a dispute with respect to any audit under Section 8.13(b), FibroGen and AstraZeneca shall work in good faith to resolve the disagreement. If the Parties are unable to reach a mutually acceptable resolution of any such dispute within thirty (30) days, the dispute shall be submitted for resolution to an independent certified public accounting firm jointly selected by each Party’s certified public accountants or to such other entity or individual as the Parties shall mutually agree (the “Auditor”). The decision of the Auditor shall be final and the costs of such resolution as well as the initial audit shall be borne between the Parties in such manner as the Auditor shall determine. Not later than ten (10) days after such decision and in accordance with such decision, the audited Party shall pay the additional amounts, with interest from the date originally due as provided in Section 8.12 or the auditing Party shall reimburse the excess payments, as applicable.

8.14 Manner and Place of Payment. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by FibroGen or AstraZeneca (as applicable), unless otherwise specified in writing by such Party. All payments hereunder shall be invoiced by the Payee to the Payor. Each invoice to AstraZeneca shall fulfill the requirements set forth on Exhibit L.

8.15 Estimated Sales and Accruals. To the extent Net Sales are based on quarterly estimates or accruals for anticipated sales of Products in the Territory, AstraZeneca shall notify FibroGen of any such estimates or accruals or adjustments or changes based on a revision in estimates and accruals within thirty (30) days of each Calendar Quarter in order to allow FibroGen to timely meet any then applicable public reporting requirements of FibroGen with respect to sales and royalties to FibroGen for Products.

ARTICLE 9

INTELLECTUAL PROPERTY

9.1 Intellectual Property Committee. The Parties shall, promptly after the Effective Date, establish an intellectual property committee (the “IP Committee”) comprised of at least one senior patent attorney from each Party, together with other representatives of the Parties as the Parties may determine to be appropriate from time to time, to review and discuss, in each case with respect to FibroGen Patents and Joint Patents, the patent prosecution strategy (including whether and where to file patent applications), Orange Book Listings, applications for patent term extension and notices of infringement, as well as the selection, registration, maintenance and defense of Marks and interest in Third Party intellectual property. The IP Committee will serve solely an advisory purpose and shall not have authority to approve or disapprove any actions with respect to patent filing, prosecution and maintenance under this Agreement.

9.2 Ownership of Inventions. Ownership of Information and inventions, whether or not patentable, made during the Term in the course of conducting activities under this Agreement, including all intellectual property rights therein (collectively, “Inventions”) shall be as follows: (a) FibroGen shall own all Inventions [*], whether made solely by employees, agents or independent

62.

contractors of either Party or its respective Affiliates, or jointly by employees, agents or independent contractors of both Parties or their respective Affiliates (collectively, “Collaboration Inventions”), (b) AstraZeneca shall own all Inventions that are made solely by employees, agents or independent contractors of AstraZeneca or its Affiliates that are not Collaboration Inventions, (c) FibroGen shall own all Inventions that are made solely by employees, agents or independent contractors of FibroGen or its Affiliates that are not Collaboration Inventions, and (d) the Parties shall jointly own all Inventions that are made jointly by employees, agents, or independent contractors of each Party or its Affiliates that are not Collaboration Inventions (“Joint Inventions”). Except to the extent either Party is restricted by the licenses granted to the other Party under this Agreement, each Party shall be entitled to practice, grant licenses to, assign and exploit the Joint Inventions and Patents claiming Joint Inventions (“Joint Patents”) without the duty of accounting or seeking consent from the other Party. AstraZeneca hereby assigns to FibroGen all of its and its Affiliates’ right, title and interest in and to the Collaboration Inventions, and agrees to take such further actions reasonably requested by FibroGen to evidence such assignment, except where such Collaboration Inventions have been made by an independent contractor retained by AstraZeneca without such contractor having agreed to assign such Collaboration Inventions to AstraZeneca, as approved by the JDC.

9.3 Disclosure of Inventions. Each Party shall promptly disclose to the other all Inventions promptly after becoming aware of them, including all invention disclosures or other similar documents submitted to such Party by its, or its Affiliates’, employees, agents or independent contractors describing such Inventions. Such Party shall also respond promptly to reasonable requests from the other Party for more Information relating to such Inventions.

9.4 Prosecution of Patents.

(a) FibroGen Patents. Except as otherwise provided in this Section 9.4(a), as between the Parties, FibroGen shall have the sole right and authority to manage all FibroGen Patent prosecution activities under this Agreement, at its sole expense. This includes the right and authority to prepare, file, prosecute and maintain all FibroGen Patents in any jurisdiction in the world, including defending such FibroGen Patents in any patent office proceedings, pre- or post-grant or issuance, including reissue, reexamination, limitation or invalidation proceedings, or any opposition- or interference-type proceeding or challenge. FibroGen shall provide AstraZeneca reasonable opportunity to review and comment on filing and prosecution efforts regarding the FibroGen Patents in the Territory. FibroGen shall, if requested by AstraZeneca, provide AstraZeneca with copies of material communications from any patent authority in the Territory regarding any FibroGen Patents, and shall if requested provide drafts of any material filings or material responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses so that AstraZeneca may have the opportunity to review and comment thereon. FibroGen shall further take into account and may include, at FibroGen’s sole discretion, any reasonable comments provided by AstraZeneca prior to submission of any such filings or responses.

(b) Requested Filings. If AstraZeneca desires FibroGen to file, in a particular jurisdiction in the Territory, a FibroGen Patent that claims priority to (or is based on the subject matter of) another FibroGen Patent, or that claims a Collaboration Invention, AstraZeneca shall provide written notice to FibroGen requesting that FibroGen file such patent application in such

63.

jurisdiction. If AstraZeneca provides such written notice to FibroGen, FibroGen shall file and prosecute such patent application and maintain any patent issuing thereon in such jurisdiction; provided that FibroGen shall not be obligated to conduct any such activities (including filing a patent application) that FibroGen reasonably believes may have an adverse effect on the FibroGen Patents anywhere in the Territory.

(c) Joint Patents. With respect to any potentially patentable Joint Invention, AstraZeneca shall have the first right, but not the obligation, to prepare patent applications based on such Joint Invention, to file and prosecute (including defense of any oppositions, interferences, reissue proceedings and reexaminations) such patent applications, and to maintain any Joint Patents issuing therefrom, in any jurisdictions throughout the Territory. FibroGen shall have the corresponding first right, but not the obligation, in any jurisdictions outside of the Territory other than China, in respect of which the China Agreement shall govern. If AstraZeneca determines in its sole discretion to abandon, cease prosecution or otherwise not file or maintain any Joint Patent anywhere in the Territory, then AstraZeneca shall provide FibroGen written notice of such determination at least thirty (30) days before any deadline for taking action to avoid abandonment (or other loss of rights) and shall provide FibroGen with the opportunity to prepare, file, prosecute and maintain such Joint Patent. The Party that is responsible for preparing, filing, prosecuting, and maintaining a particular Joint Patent (the “Prosecuting Party”) shall provide the other Party reasonable opportunity to review and comment on such prosecution efforts regarding such Joint Patent, and such other Party shall provide the Prosecuting Party reasonable assistance in such efforts. The Prosecuting Party shall provide the other Party with a copy of all material communications from any patent authority in the applicable jurisdictions regarding the Joint Patent being prosecuted by such Party, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. In particular, each Party agrees to provide the other Party with all information necessary or desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any patent authority. Either Party may determine that it is no longer interested in supporting the continued prosecution or maintenance of a particular Joint Patent in a country or jurisdiction, in which case: (i) the disclaiming Party shall, if requested in writing by the other Party, assign its ownership interest in such Joint Patent in such country or jurisdiction to the other Party for no additional consideration; and (ii) if such assignment is effected, any such Joint Patent would thereafter be deemed a FibroGen Patent in the case of assignment to FibroGen, or a AstraZeneca Patent in the case of assignment to AstraZeneca; provided, however, that the disclaiming party would have an immunity from suit under such FibroGen Patent or AstraZeneca Patent, as the case may be, in the applicable country or jurisdiction. In addition, any Joint Patent that becomes a FibroGen Patent pursuant to the preceding sentence shall be excluded from the license granted to AstraZeneca in Section 7.1. Each Party shall bear its own internal costs in respect of the prosecution of Joint Patents. Out-of-pocket costs incurred in respect of the prosecution and maintenance of Joint Patents in the Territory shall be borne equally by AstraZeneca and FibroGen. In the event a Party elects to disclaim its interest in a Joint Patent, the costs incurred with respect to such Patent after the date of such disclaimer shall thereafter be borne exclusively by the other Party, without reimbursement or credit.

(d) Cooperation in Prosecution. Each Party shall, through the IP Committee, provide the other Party all reasonable assistance and cooperation in the Patent prosecution efforts provided above in this Section 9.4, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution.

64.

(ii) If there is any infringement, threatened infringement, imminent infringement or alleged infringement of any FibroGen Patent on account of a Third Party’s manufacture, use, offer for sale, or sale of a Collaboration Compound or Product in the Territory not within Section 9.5(a)(i) (“Other Infringement”) then each Party shall promptly notify the other Party in writing of any such Other Infringement of which it becomes aware, and shall provide evidence in such Party’s possession demonstrating such Other Infringement.

(b) Enforcement Rights.

(i) RoW Litigation. AstraZeneca shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity allegedly engaged in any Product Infringement or Other Infringement of the FibroGen Patents in the RoW (and to defend any related counterclaim), at AstraZeneca’s expense. AstraZeneca shall have a period of one hundred eighty (180) days after its receipt or delivery of notice and evidence pursuant to Section 9.5(a)(i), to elect to so enforce such FibroGen Patent in the RoW (or to settle in accordance with Section 9.5(c) or otherwise secure the abatement of such Product Infringement or Other Infringement). In the event AstraZeneca does not so elect (or settle or otherwise secure the abatement of such Product Infringement or Other Infringement), it shall so notify FibroGen in writing as soon as practicable following the decision and in any event within such one hundred eighty (180)-day period, and FibroGen shall have the right to commence a suit or take action to enforce the applicable FibroGen Patents with respect to such Product Infringement or Other Infringement in the RoW (and to defend any related counterclaim) at FibroGen’s expense. The IP Committee shall take the necessary actions to ensure that AstraZeneca has proper standing to bring suit under this Section 9.5(b)(i).

(ii) U.S. Litigation. AstraZeneca shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity allegedly engaged in any Product Infringement or Other Infringement of the FibroGen Patents in the U.S. (and to defend any related counterclaim), at AstraZeneca’s expense. AstraZeneca shall have a period of thirty (30) days, with respect to a Product Infringement, and one hundred eighty (180) days with respect to an Other Infringement, after its receipt or delivery of notice and evidence

65.

pursuant to Section 9.5(a)(i), to elect to so enforce such FibroGen Patent in the U.S. (or to settle in accordance with Section 9.5(c) or otherwise secure the abatement of such Product Infringement or Other Infringement). The Parties shall meet periodically to discuss in good faith and determine an enforcement strategy, and AstraZeneca shall act consistently with any such agreed strategy. In the event AstraZeneca does not so elect (or settle or otherwise secure the abatement of such Product Infringement or Other Infringement), it shall so notify FibroGen in writing as soon as practicable following the decision and in any event within such thirty (30)- or one hundred eighty (180)-day period, as applicable, and FibroGen shall have the right to commence a suit or take action to enforce the applicable FibroGen Patents with respect to such Product Infringement or Other Infringement in the U.S. (and to defend any related counterclaim), at FibroGen’s expense. The IP Committee shall take the necessary actions to ensure that AstraZeneca has proper standing to bring suit under this Section 9.5(b)(ii).

(iii) Cooperation. In any action, suit or proceeding instituted under this Section 9.5(b), the Parties shall cooperate with and assist each other in all reasonable respects. Upon the reasonable request of the Party instituting such action, suit or proceeding, the other Party shall join such action, suit or proceeding and shall be represented using counsel of its own choice, at the requesting Party’s expense. If a Party with the right to initiate legal proceedings under this Section 9.5(b) lacks standing to do so and the other Party has standing to initiate such legal proceedings, then the Party with standing shall initiate such legal proceedings at the request and expense of the other Party (including reasonable internal personnel costs at the Hourly Rate).

(c) Settlement. Without the prior written consent of the other Party, neither Party shall settle any claim, suit or action that it brought under Section 9.5(b) involving FibroGen Patents in any manner that would negatively impact such intellectual property or that would limit or restrict the ability of either Party to sell Products anywhere in or outside the Territory.

(d) Recoveries. If either Party recovers monetary damages from a Third Party in a suit or action in respect of a Product Infringement or Other Infringement, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation and any remaining amount shall be deemed Net Sales and retained by (or paid to) AstraZeneca, subject to royalty payments on such deemed Net Sales pursuant to Section 8.6.

(e) Designated Products. Notwithstanding anything to the contrary in this Agreement:

(i) FibroGen shall have the sole right to enforce the FibroGen Patents against any of the Designated Products (“Designated Product Infringement”), and AstraZeneca shall be solely responsible for all expenses reasonably incurred in connection therewith and subject further to (ii) below. FibroGen will invoice AstraZeneca for its share of such expenses on a Calendar Quarter basis (including its internal personnel costs at the Hourly Rate), and AstraZeneca will pay each such invoice within forty-five (45) days after receipt thereof.

(ii) Notwithstanding (i) above, (A) in no event shall [*]; provided that in Calendar Years 2018, 2019 and 2020, AstraZeneca shall not be obligated to [*], except that if AstraZeneca reimburses [*] (the “Deficit”), the [*] (see example below); (B) in enforcing the FibroGen Patents against any of the Designated Products, the Parties shall unanimously select

outside counsel to represent FibroGen in such enforcement proceedings (failing such unanimous agreement AstraZeneca shall be [*] (C) FibroGen shall, at all times, keep AstraZeneca reasonably informed regarding such enforcement proceedings and shall take into account any good faith comments made by AstraZeneca relating to such enforcement proceedings; and (D) FibroGen shall provide AstraZeneca with reasonably sufficient information regarding such enforcement proceedings to demonstrate that any such proceedings have a good faith basis and are brought and maintained in good faith. By way of example of clause (A), [*].

(f) Non-Product-Related Infringements. As between the Parties, FibroGen shall have the sole right to enforce the FibroGen Patents in the Territory against any infringement, imminent infringement, threatened infringement or alleged infringement that is not a Product Infringement, a Designated Product Infringement or an Other Infringement, at its expense, and to retain all associated recoveries; provided that in no event will FibroGen place an Orange Book-listed FibroGen Patent (or a FibroGen Patent listed on a Form 3542 submitted in accordance with Section 9.12 upon or after approval of the NDA as a timely filed patent) into litigation without AstraZeneca’s prior written approval, which approval will not be unreasonably withheld.

(g) Joint Patents. Each Party shall promptly notify the other Party upon becoming aware of any infringement, imminent infringement, threatened infringement or alleged infringement of any Joint Patent (“Joint Patent Infringement”). The Parties will promptly thereafter meet to discuss in good faith how and whether to proceed to enforce the applicable Joint Patent against such Joint Patent Infringement. If the Parties fail to agree within sixty (60) days, then either Party shall have the right to take any action permitted under applicable law.

(h) Patents Licensed from Third Parties. Each Party’s rights under this Section 9.5 with respect to any FibroGen Patent licensed from a Third Party shall be subject to the rights of such Third Party to enforce such FibroGen Patent and/or defend against any claims that such FibroGen Patent is invalid or unenforceable.

9.6 Defense of FibroGen Patents. To the extent any Party receives notice by counterclaim, or otherwise, alleging the invalidity or unenforceability of any FibroGen Patent in the Territory, it shall bring such fact to the attention of the other Party, including all relevant information related to such claim. The Parties, through the JSC, shall discuss such claim. Where such allegation is made within the context of a patent office proceeding, the provisions of Section 9.4 shall apply. Where such allegation is made in a counterclaim to or in connection with a suit or other action brought under Section 9.5, the provisions of Section 9.5 shall apply. In all other cases, (a) where such action relates to a FibroGen Patent in the U.S., FibroGen shall have the first right to defend such action, at FibroGen’s expense, and AstraZeneca will cooperate with FibroGen, at FibroGen’s expense, in such defense, and (b) where such action relates to a FibroGen Patent within the RoW, AstraZeneca shall have the first right but not the obligation to defend such action, at AstraZeneca’s expense, and FibroGen will cooperate with AstraZeneca, at AstraZeneca’s expense, in such defense. In the event a Party does not so elect to exercise its first right to defend an action under this Section 9.6, it shall so notify the other Party in writing, and such other Party shall have the right to so defend such action at its expense. Each Party shall provide to the Party defending any such rights under this Section 9.6 all reasonable assistance in such enforcement, at such defending Party’s request and expense. The defending Party shall keep the other Party regularly informed of the status and progress of such efforts, and shall reasonably consider the other Party’s comments on any such efforts.

67.

9.7 Third Party Patents. FibroGen shall have the sole right and authority to initiate and/or pursue at its sole expense any patent office proceeding, pre- or post-grant or issuance, including reissue, reexamination, limitation, or invalidation proceedings, or any opposition- or interference-type proceeding or challenge against any Third Party Patent that relates or that may potentially relate to the manufacture, use, or sale of a HIF Compound, a Product, or a Designated Product.

9.8 Defense of Infringement Actions. During the Term, each Party shall bring to the attention of the other Party all information regarding potential infringement or any claim of infringement of Third Party intellectual property rights in connection with the development, manufacture, production, use, importation, offer for sale, or sale of Products in the Territory. Subject to Article 11, each Party shall be solely responsible at its sole expense for defending any action, suit, or other proceeding brought against it alleging infringement of Third Party intellectual property rights in connection with its activities under this Agreement. This Section 9.8 shall not be interpreted as placing on either Party a duty of inquiry regarding Third Party intellectual property rights.

9.9 Patent Marking. AstraZeneca shall, and shall require its Affiliates and Sublicensees to, xxxx Products sold by it hereunder (in a reasonable manner consistent with industry custom and practice) with appropriate patent numbers or indicia to the extent permitted by applicable law and regulations, in those countries in which such markings or such notices impact recoveries of damages or equitable remedies available with respect to infringements of patents. The Parties agree that listing the appropriate Patent(s) in the Orange Book shall be deemed a marking in a reasonable manner consistent with industry custom and practice under this Section 9.9, and FibroGen agrees to use good faith efforts to obtain, as soon as reasonably practicable after the Effective Date, a written confirmation from DFCI that DFCI so agrees.

9.10 Personnel Obligations. Prior to beginning work under this Agreement relating to any research, Development or Commercialization of a Collaboration Compound or a Product, to HIF or in the Field, each employee, agent or independent contractor of AstraZeneca or FibroGen or of either Party’s respective Affiliates shall be bound by non-disclosure and invention assignment obligations which are consistent with the obligations of AstraZeneca or FibroGen, as appropriate, in this Article 9, including without limitation: (a) promptly reporting any invention, discovery, process or other intellectual property right; (b) assigning to AstraZeneca or FibroGen, as appropriate, all of his or her right, title and interest in and to any invention, discovery, process or other intellectual property right, such that AstraZeneca or FibroGen, as appropriate, can then comply with its obligations under this Agreement with respect to such invention, discovery, process or other intellectual property right; (c) cooperating in the preparation, filing, prosecution, maintenance and enforcement of any patent and patent application; (d) performing all acts and signing, executing, acknowledging and delivering any and all documents required for effecting the obligations and purposes of this Agreement; and (e) abiding by the obligations of confidentiality and non-use set forth in Article 12. It is understood and agreed that such non-disclosure and invention assignment agreement need not reference or be specific to this Agreement.

68.

9.11 Trademarks. The Parties shall use Commercially Reasonable Efforts to develop a worldwide trademark, and if not possible, trademark for the Territory consistent with the trademarks for Products selected under the Astellas Collaboration. AstraZeneca, following discussion with FibroGen, shall be responsible for the selection, registration, ownership, maintenance and defense of all trademarks for use in connection with the sale or marketing of Products in the Field in the Territory (the “Marks”), as well as all expenses associated therewith. All uses of the Marks shall be reviewed by the JCC and shall comply with all applicable laws and regulations (including those laws and regulations particularly applying to the proper use and designation of trademarks in the applicable countries). Neither Party shall, without the other Party’s prior written consent, use any trademarks or house marks of the other Party (including the other Party’s corporate name), or marks confusingly similar thereto, in connection with such Party’s marketing or promotion of Products under this Agreement, except as may be expressly authorized in connection with activities under Article 5 and except to the extent required to comply with applicable laws and regulations. During the Term, AstraZeneca grants to FibroGen the non-exclusive right, free of charge, to use the AstraZeneca name and logo in the U.S. solely for the purpose of Commercializing the Products in accordance with the terms of this Agreement, the U.S. Commercialization Plan and the Co-Commercialization Agreement, and FibroGen grants to AstraZeneca the non-exclusive right, free of charge, to use the FibroGen name and logo in the U.S. solely for the purpose of Commercializing the Products in accordance with the terms of this Agreement, provided that such rights shall be exercised, and all Products bearing such names and/or logos shall be manufactured, in accordance with the quality standards for such logos and trademarks established by the JSC. AstraZeneca shall remain the owner of the AstraZeneca name and logo and the trademarks and the goodwill pertaining thereto. FibroGen shall remain the owner of the FibroGen name and logo and the trademarks and the goodwill pertaining thereto.

9.12 Listing. Prior to the submission of the first NDA of a Product in the U.S., the Parties shall discuss in good faith in the IP Committee the Orange Book listings. FibroGen shall be responsible for the submission of documents associated with Orange Book listings in accordance with the plan set forth by the IP Committee. Upon FibroGen’s receipt of a notice of allowance (or equivalent) of an applicable FibroGen Patent, FibroGen shall promptly provide AstraZeneca notification of such allowance and the Parties shall discuss in good faith in the IP Committee whether to list such FibroGen Patent in the Orange Book maintained by the FDA or similar or equivalent patent listing source, if any, in other countries in the Territory. FibroGen shall cooperate with AstraZeneca’s reasonable requests in connection therewith, including meeting any submission deadlines.

9.13 Patent Term Extension. AstraZeneca shall be responsible for and control, but shall confer with FibroGen in, the selection of the appropriate FibroGen Patents as listed in the patent information section of the NDA or MAA for Products for filing to obtain a Patent Term Extension pursuant to all applicable laws, including without limitation any other extensions that are now or become available in the future wherever applicable to such patents that are applicable to the Products; provided, however, that AstraZeneca shall not have the right to make any such filing with respect to any FibroGen Patent that is not set forth on Exhibit M without the prior written consent of FibroGen.

(d) No Debarment. In the course of the Development of Products, such Party has not used prior to the Effective Date and shall not use, during the Term, any employee, agent or independent contractor who has been debarred by any Regulatory Authority, or, to the best of such Party’s knowledge, is the subject of debarment proceedings by a Regulatory Authority.

10.2 Representations and Warranties by FibroGen. FibroGen hereby represents and warrants to AstraZeneca, as of the Effective Date, as follows:

(a) Title; Encumbrances. Except for the Patents licensed to FibroGen under the DFCI Agreement and the Information licensed to FibroGen under the Astellas Agreements, FibroGen is the sole and exclusive owner of the entire right, title and interest in (a) the Listed Patents and (b) the FibroGen Know-How existing as of the Effective Date. FibroGen has all rights necessary to grant the licenses under the FibroGen Technology that it grants to AstraZeneca under this Agreement. Neither the Listed Patents nor the FibroGen Know-How is subject to any mortgage, pledge, lien, security interest, conditional and installment sale agreements, encumbrance or charges or claims of any kind.

(b) No Other Patents than those Listed. The Listed Patents represent all Patents that, as of the Effective Date, are Controlled by FibroGen and which, to FibroGen’s knowledge, cover or claim any invention necessary or useful for the Development or Commercialization of Collaboration Compounds or Products in the Field in the Territory as contemplated as of the Effective Date.

70.

(c) Prosecution of Patents etc. To FibroGen’s knowledge, the Listed Patents are being diligently prosecuted before the respective patent authorities in accordance with applicable law. All applicable fees due to patent authorities with respect to the filing and prosecution of the Listed Patents existing as of the Effective Date have been paid on or before the due date for payment (as such due date may be extended in accordance with applicable laws or patent authority rules and regulations). FibroGen has not received any written notice alleging that the Listed Patents existing as of the Effective Date, if issued, would be invalid or unenforceable or that the Patent applications included in such Listed Patents will not proceed to grant. To FibroGen’s knowledge, in respect of any pending U.S. patent applications included in the Listed Patents, FibroGen has submitted all material prior art of which it is aware in accordance with the requirements of the United States Patent and Trademark Office. To its knowledge, FibroGen has properly identified each and every inventor of the claims of the Listed Patents existing as of the Effective Date.

(d) No Infringement or Misappropriation. FibroGen has not received any written notice from any Third Party asserting or alleging that any research or development of Collaboration Compounds or Products by FibroGen or by Astellas prior to the Effective Date infringed or misappropriated the intellectual property rights of such Third Party and FibroGen has no reason to suspect that any such infringement or misappropriation has occurred. To FibroGen’s knowledge, the conception, development and reduction to practice of the Listed Patents and FibroGen Know-How existing as of the Effective Date have not constituted or involved the misappropriation of trade secrets or other proprietary rights of any person or entity.

(e) Non-infringement of Third Party Rights. To FibroGen’s knowledge, the research, development, manufacture, use and sale after the Effective Date of FG-4592 in the CKD Indications can be carried out in the manner reasonably contemplated as of the Effective Date without infringing any published patent applications or patents owned or controlled by a Third Party.

(f) No Proceedings. There are no pending actions, suits or proceedings against FibroGen or any of its Affiliates involving the FibroGen Technology, Collaboration Compounds or Products.

(g) Third Party Activities. To FibroGen’s knowledge, except as disclosed in a writing of even date herewith by FibroGen to AstraZeneca, there are no activities by Third Parties that would constitute infringement or misappropriation of the FibroGen Technology (in the case of pending claims, evaluating them as if issued).

(h) DFCI Agreement. The DFCI Agreement is in full force and effect. FibroGen has no cause to believe that the DFCI Agreement is likely to be terminated prior to its expiry. To FibroGen’s knowledge, neither DFCI nor FibroGen is in breach of any of its obligations under the DFCI Agreement. [*].

(i) Astellas Agreements. Nothing in the Astellas Agreements prevents FibroGen from granting the rights to AstraZeneca granted under this Agreement or prevents either FibroGen or AstraZeneca from exercising their rights or performing their obligations under this Agreement.

71.

(j) Documentation Made Available to AstraZeneca. FibroGen has made available to AstraZeneca all material Regulatory Material, FibroGen Know-How and other Information in its possession or Control regarding or related to any Collaboration Compound and Product. All Regulatory Material, FibroGen Know-How and other Information in FibroGen’s possession and Control provided to AstraZeneca regarding or related to any Collaboration Compound or Product are, to FibroGen’s knowledge, true, complete and correct in all material respects. As of the Effective Date, FibroGen has prepared, maintained and retained in all material respects all material Regulatory Material that FibroGen is required to maintain or report pursuant to and in accordance with GLP, GCP, regulations and other applicable law.

(k) Patent Litigation. Neither FibroGen nor its Affiliates will initiate or maintain any patent enforcement proceeding or litigation with respect to any Designated Product unless it has a good faith basis for doing so.

(a) Each Party agrees, on behalf of itself, its officers, directors and employees and on behalf of its Affiliates, agents, representatives, consultants and subcontractors hired in connection with the subject matter of this Agreement (together with such Party, the “Representatives”) that for the performance of its obligations hereunder:

(i) The Representatives shall not directly or indirectly pay, offer or promise to pay, authorize the payment of any money or give, offer or promise to give, or authorize the giving of anything else of value, to: (a) any Government Official in order to influence official action; (b) any individual or entity (whether or not a Government Official) (1) to influence such individual or entity to act in breach of a duty of good faith, impartiality or trust (“acting improperly”), (2) to reward such individual or entity for acting improperly or (3) where such individual or entity would be acting improperly by receiving the money or other thing of value; (c) any individual or entity (whether or not a Government Official) while knowing or having reason to know that all or any portion of the money or other thing of value will be paid, offered, promised or given to, or will otherwise benefit, a Government Official in order to influence official action for or against either Party in connection with the matters that are the subject of this Agreement; or (d) any individual or entity (whether or not a Government Official) to reward that individual or entity for acting improperly or to induce that individual or entity to act improperly.

Such other Party shall ensure that any Third Party auditor enters into a confidentiality agreement consistent with applicable requirements of Article 12 hereof in all material respects. Such other Party shall instruct any Third Party auditor or other Person given access in respect of a Compliance Audit to cause the minimum amount of disruption to the business of the audited Party and its Affiliates and to comply with relevant building and security regulations.

(iii) The costs and fees of any Compliance Audit shall be paid by the auditing Party, except that if an inspection or Compliance Audit reveals any breach or violation by the audited Party (including through its other Representatives) of any representation, warranty or

73.

undertaking set forth in Sections 10.3(a)-(c), the costs of such inspection or Compliance Audit shall be paid by the audited Party. The audited Party shall bear its own costs of rendering assistance to the Compliance Audit.

(f) On the occurrence of any of the following events: (A) A Party becomes aware of, whether or not through a Compliance Audit, that the other Party (or any other Representative) is in breach or violation of any representation, warranty or undertaking in Sections 10.3(a)-(c) or of the Anti-Corruption Laws; or (B) notification is received under Section 10.3(d) relating to any suspected or actual Material Anti-Corruption Law Violation by a Party or its Representative, in either case ((A) or (B)), the other Party shall have the right, in addition to any other rights or remedies under this Agreement or to which such other Party may be entitled in law or equity, to (x) take such steps as are reasonably necessary in order to avoid a potential violation or continuing violation by such other Party or any of its Affiliates of the Anti-Corruption Laws, including by requiring that the Party agrees to such additional measures, representations, warranties, undertakings and other provisions as such other Party believes in good faith are reasonably necessary (“Provisions”) and (y) terminate any or all of the activities conducted by the Party pursuant to this Agreement or this Agreement in its entirety, immediately in the event that:

(ii) A Party reasonably concludes that there is no Provision available that would enable such Party or its Affiliates to avoid a potential violation or continuing violation of applicable Anti-Corruption Laws.

(g) Any termination of this Agreement pursuant to Section 10.3(f) shall be treated as a termination for breach and the consequences of termination set forth in Sections 13.6 and 13.7, as applicable, shall apply and additionally: (i) subject to the accrued rights of the Parties prior to termination, the terminating Party shall have no liability to the other Party for any fees, reimbursements or other compensation or for any loss, cost, claim or damage resulting, directly or indirectly, from such termination; and (ii) any amounts that would otherwise be payable with respect to such terminated activities or pursuant to this Agreement in its entirety, as applicable, including any then outstanding and unpaid claims for payment shall be null and void to the extent permissible under applicable laws.

(h) Each Party shall be responsible for any breach of any representation, warranty or undertaking in this Section 10.3 or of the Anti-Corruption Laws by any of its Representatives.

74.

11.1 Indemnification by FibroGen. FibroGen shall defend, indemnify, and hold AstraZeneca, its Affiliates, and their respective officers, directors, employees, and agents (the “AstraZeneca Indemnitees”) harmless from and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such AstraZeneca Indemnitees (collectively, “AstraZeneca Damages”), all to the extent resulting from claims, suits, proceedings or causes of action brought by such Third Party (“AstraZeneca Claims”) against such AstraZeneca Indemnitee that arise from or are based on: (a) a breach of any of FibroGen’s representations, warranties, and obligations under this Agreement;

75.

(b) the willful misconduct or grossly negligent acts or omissions of FibroGen, its Affiliates, or the officers, directors, employees, or agents of FibroGen or its Affiliates in the performance of activities under this Agreement; (c) the research or Development of Collaboration Compounds or Products by FibroGen before the Effective Date; or (d) the Development, testing, manufacture, storage, handling, use, sale, offer for sale, distribution and importation of Products by FibroGen or its Affiliates or licensees (excluding, for clarity, AstraZeneca). The foregoing indemnity obligation shall not apply if the AstraZeneca Indemnitees materially fail to comply with the indemnification procedures set forth in Section 11.3, or to the extent that such AstraZeneca Claim is based on or alleges: (i) a breach of any of AstraZeneca’s representations, warranties, and obligations under this Agreement; or (ii) the willful misconduct or grossly negligent acts or omissions of AstraZeneca or its Affiliates, or the officers, directors, employees, or agents of AstraZeneca or its Affiliates in the performance of activities under this Agreement.

11.2 Indemnification by AstraZeneca. AstraZeneca shall defend, indemnify, and hold FibroGen, its Affiliates, and each of their respective officers, directors, employees, and agents, (the “FibroGen Indemnitees”) harmless from and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such FibroGen Indemnitees (collectively, “FibroGen Damages”), all to the extent resulting from any claims, suits, proceedings or causes of action brought by such Third Party (collectively, “FibroGen Claims”) against such FibroGen Indemnitee that arise from or are based on: (a) the Development, testing, manufacture, storage, handling, use, sale, offer for sale, distribution and importation of Products by AstraZeneca or its Affiliates, Sublicensees, or distributors; (b) a breach of any of AstraZeneca’s representations, warranties, and obligations under the Agreement; or (c) the willful misconduct or grossly negligent acts or omissions of AstraZeneca or its Affiliates, or the officers, directors, employees, or agents of AstraZeneca or its Affiliates in the performance of activities under this Agreement. The foregoing indemnity obligation shall not apply if the FibroGen Indemnitees materially fail to comply with the indemnification procedures set forth in Section 11.3, or to the extent that any FibroGen Claim is based on or alleges: (i) a breach of any of FibroGen’s representations, warranties, and obligations under this Agreement; or (ii) the willful misconduct or grossly negligent acts or omissions of FibroGen, its Affiliates, or their officers, directors, employees, or agents in the performance of activities under this Agreement.

11.3 Indemnification Procedures. The Party claiming indemnity under this Article 11 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of the claim, suit, proceeding or cause of action for which indemnity is being sought (“Claim”). The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. So long as the Indemnifying Party is actively defending the Claim in good faith, the Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend

76.

against, and consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article 11.

Each Party shall self-insure or procure and maintain insurance, including product liability insurance, with respect to its activities hereunder and which are consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being clinically tested in human subjects or commercially distributed or sold until the expiration or termination of this Agreement or four (4) years after termination of any such clinical testing or commercial distribution, whichever is later. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 11. Each Party shall provide the other with written evidence of such insurance upon request. Each Party shall provide the other with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance or self-insurance which materially adversely affects the rights of the other Party hereunder.

11.5 DFCI Agreement. [*]

ARTICLE 12

CONFIDENTIALITY

12.1 Product Information. FibroGen recognizes that by reason of, among other things, AstraZeneca’s status as licensee pursuant to the grants under Section 7.1, AstraZeneca has an interest in FibroGen’s retention in confidence of information relating to the Collaboration Compounds or Products, and the Development and Commercialization thereof. Accordingly, during the Term, FibroGen shall, and shall cause its Affiliates and their respective officers, directors, employees and agents to, keep confidential, and not publish or otherwise disclose, other than under written confidentiality and non-use terms, and not use directly or indirectly for any purpose other than to perform FibroGen’s obligations under this Agreement and the China Agreement, to conduct research, Development and Commercialization of Products outside the Territory pursuant to the Astellas Agreements or any Subsequent Agreement entered into pursuant to Section 7.4(c), in connection with FibroGen’s research, development and commercialization of other products, and as otherwise authorized under this Agreement (including pursuant to Section 3.10), any (a) Regulatory Material (including any Regulatory Approvals) with respect to any Collaboration Compound or Product and (b) Information that is either Controlled by FibroGen or provided to FibroGen pursuant to this Agreement relating to the Development or Commercialization of Collaboration Compounds or Products, including development, sales or marketing plans therefor (collectively, (a) and (b), “Product Information”), except, in each case, to the extent (i) the Product Information was generally available to the public or otherwise part of the public domain, prior to the Effective Date, or thereafter became generally available to the public or otherwise part of the public domain through no fault of FibroGen, its Affiliates or any of their respective officers, directors, employees or agents or (ii) the disclosure or use of such Product Information would be expressly permitted under Section 12.3 or is otherwise expressly authorized under this Agreement. For clarification, the disclosure or transfer by FibroGen to AstraZeneca or

77.

by AstraZeneca to FibroGen of any Product Information shall not cause such information to cease to be subject to the provisions of this Section 12.1. In the event this Agreement is terminated in its entirety or in a given country for any reason, this Section 12.1 shall as from the effective date of such termination have no continuing force or effect (provided that if such termination is with respect to one or several specific country(ies) only, then this Section 12.1 will have no continuing force or effect as to such specific country(ies)) and all Product Information shall be deemed to be Confidential Information of FibroGen for purposes of the surviving provisions of this Agreement. For clarity, the foregoing shall not affect the Parties’ respective ownership of Product Information.

12.2 Confidentiality General. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, each Party agrees that, during the Term and for ten (10) years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement or the China Agreement (which includes the exercise of any rights or the performance of any obligations hereunder or thereunder) any Confidential Information furnished to it by the other Party pursuant to this Agreement except for that portion of such information or materials that the receiving Party can demonstrate by competent written proof:

(a) was already known to the receiving Party or its Affiliate, other than under an obligation of confidentiality, at the time of disclosure by the other Party;

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

(c) 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 in breach of this Agreement;

(d) is subsequently disclosed to the receiving Party or its Affiliate by a Third Party without obligations of confidentiality with respect thereto; or

(e) is independently discovered or developed by the receiving Party or its Affiliate without the aid, application, or use of the disclosing Party’s Confidential Information.

For the avoidance of doubt, Confidential Information that is also Product Information is governed both by the terms of Section 12.1 and by the terms of this Section 12.2.

12.3 Authorized Disclosure. FibroGen may disclose Product Information and each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following situations:

(a) filing or prosecuting FibroGen Patents in accordance with Article 9;

(b) regulatory filings and other filings with Governmental Authorities (including Regulatory Authorities), including filings with the SEC or FDA, with respect to a Product;

(c) prosecuting or defending litigation;

78.

(d) complying with applicable laws and regulations, including regulations promulgated by securities exchanges;

(e) disclosure to its Affiliates, employees, agents, and independent contractors, and any licensees or Sublicensees, in each case only on a need-to-know basis and solely in connection with the performance of this Agreement or the China Agreement (and in the case of FibroGen, the Astellas Collaboration or any Subsequent Agreement entered into pursuant to Section 7.4(c)), provided, however, that each disclosee must be bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 12 prior to any such disclosure and provided, further, that the disclosing Party shall cause such disclosee to comply with confidentiality and non-use obligations at least as restrictive as those set forth in this Article 12;

(f) disclosure of the material terms of this Agreement to any bona fide potential or actual investor, investment banker, acquirer, merger partner, or other potential or actual financial partner, and in the case of FibroGen, to any licensee or sublicensee of Products (including Astellas and its sublicensees); provided that in connection with such disclosure, the disclosing Party shall inform each disclosee of the confidential nature of such Confidential Information and cause each disclosee to treat such Confidential Information as confidential; and

(g) disclosure of any Inventions or status reports (including data from any Clinical Trials) to any bona fide potential or actual investor, investment banker, acquirer, merger partner, or other potential or actual financial partner, and in the case of FibroGen, to any licensee of Products (including Astellas and its sublicensees); provided that each disclosee must be bound by obligations of confidentiality and non-use at least as restrictive as those set forth in this Article 12 prior to any such disclosure.

Notwithstanding the foregoing, in the event FibroGen is required to make a disclosure of Product Information or either Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Sections 12.3(a), 12.3(b), 12.3(c) or 12.3(d), it will, except where impracticable, use Commercially Reasonable Efforts to secure confidential treatment of such information. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder.

12.4 Publicity; Terms of Agreement.

(a) The Parties agree that the material terms of this Agreement are the Confidential Information of both Parties, subject to the special authorized disclosure provisions set forth in Section 12.3 and this Section 12.4. The Parties have agreed to make a joint public announcement of the execution of this Agreement substantially in the form of the press release attached as Exhibit N on or promptly after the Effective Date.

(b) After release of such press release, if either Party desires to make a public announcement concerning the material terms of this Agreement or any activities under this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (except as otherwise provided herein), such approval not to be unreasonably withheld, except that in the case of a press release or

79.

governmental filing required by law, the disclosing Party shall provide the other Party with such advance notice as it reasonably can and shall not be required to obtain approval therefor. A Party commenting on such a proposed press release shall provide its comments, if any, within five (5) Business Days after receiving the press release for review. FibroGen shall have the right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved, and the achievements of Regulatory Approvals as they occur, subject only to the review procedure set forth in the preceding sentence. In relation to AstraZeneca’s review of such an announcement, AstraZeneca may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the information that the relevant milestone or Regulatory Approval has been achieved and triggered a payment hereunder. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that have already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 12.4.

(a) Rights and Licenses to the FibroGen Technology. As from the effective date of the termination, all licenses and rights to the FibroGen Technology granted to AstraZeneca under Article 7 shall terminate with respect to the terminated region, except to the extent and for so long as is necessary to permit AstraZeneca to comply with its obligations under this Section 13.6, to dispose of any remaining inventory of Products pursuant to Section 13.6(g) and to perform any activity that cannot be terminated as of such date under applicable law, including GCP, it being agreed that all such activities and responsibilities shall be discontinued and ceased (unless otherwise agreed) by transitioning such activities and responsibilities to FibroGen as soon as practicable and subject to applicable law, including GCP.

(b) AstraZeneca Technology. AstraZeneca hereby grants to FibroGen, effective only upon the effective date of such termination, a non-exclusive, fully-paid, perpetual,

82.

irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses, under the AstraZeneca Technology, to research, develop, make, have made, use, import, export, offer for sale, and sell Products in the Field in the terminated region; provided that FibroGen shall indemnify, defend and hold harmless AstraZeneca and each of the AstraZeneca Indemnitees as set forth in Section 11.1 from and against any AstraZeneca Damages arising out of or resulting from AstraZeneca Claims that arise or result from FibroGen’s, its Affiliates’ or licensees’ activities performed under the foregoing license.

The foregoing consultation and assistance shall include, without limitation, assigning, upon request of FibroGen, 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 (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 to commence or continue developing, manufacturing, or commercializing Products, then AstraZeneca shall reasonably cooperate with FibroGen 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 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 if AstraZeneca is unable to timely effect the technology transfer required to have a Third Party manufacturer designated by FibroGen undertake the manufacturing responsibilities) under the terms of such agreement until FibroGen either enters into a separate agreement with such Third Party supplier or vendor or establishes an alternate, validated source of supply for the Products. In consideration of such supplies, FibroGen 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 shall pay to AstraZeneca a price equal to AstraZeneca’s actual cost to manufacture or acquire such supplies plus a xxxx-up [*] of such actual cost.

83.

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

(g) Remaining Inventories. If this Agreement is terminated in its entirety, FibroGen 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 the 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 shall notify AstraZeneca within sixty (60) days after the effective date of the termination whether FibroGen elects to exercise such right. In the event FibroGen does not elect to exercise such right AstraZeneca shall be entitled to dispose of such inventory as it sees fit in compliance with applicable law, subject to all applicable payments to FibroGen under Article 8.

(h) Funding of Development Costs. If AstraZeneca terminates this Agreement under Section 13.2 (but not in the event of any other termination), then AstraZeneca shall remain responsible for all (or, if during the Development Sharing Period, fifty percent (50%) of) Development Costs and all Commercialization Costs incurred by FibroGen under the respective Development Plans and Commercialization Plans [*], under the process in Section 8.2. If AstraZeneca terminates this Agreement under Section 13.2 (but not in the event of any other termination), AstraZeneca shall [*].

(j) No Other Rights. For the avoidance of doubt, the rights granted to FibroGen 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 with any other intellectual property rights or other rights or services than that which are explicitly provided for under this Section 13.6.

(k) Certain Additional Provisions for Termination for FibroGen’s Breach. If this Agreement is terminated under Section 13.4 for FibroGen’s material breach, FibroGen 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 this Section 13.6.

13.7 Effect of Termination for Technical Product Failure. Upon termination of this Agreement pursuant to Section 13.3 for a Technical Product Failure, all licenses and rights to the FibroGen Technology granted to AstraZeneca under Article 7 shall terminate and, to the extent appropriate given the nature of the Technical Product Failure and subject to applicable law, including GCP, the other termination consequences set out in Sections 13.6(a) through 13.6(g) as well as Section 13.6(j) shall apply.

84.

15.5 Assignment. Neither Party may assign or transfer this Agreement (either in whole or part) or any rights or obligations hereunder without the prior written consent of the other, except that a Party may make such an assignment or transfer without the other Party’s consent to Affiliates or to a successor to substantially all of the business of such Party, whether in a merger, sale of stock, sale of assets or other transaction.

property of such Acquiror shall be included within FibroGen Technology (in the case when the acquired Party is FibroGen) and AstraZeneca Technology (in the case when the acquired Party is AstraZeneca). Any permitted assignment of the rights and obligations of a Party under this Agreement shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 15.5 shall be null, void and of no legal effect.

15.6 Performance by Affiliates. Subject to the limitations of Section 7.3, each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

15.7 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

15.8 Compliance with Applicable Law. Each Party shall comply with all applicable laws and regulations in the course of performing its obligations or exercising its rights pursuant to this Agreement.

15.9 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT OR ANY TORT CLAIMS ARISING HEREUNDER, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 15.9 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 11.1, 11.2 OR 11.3, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE 12.

15.10 Severability. 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. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one that achieves, as nearly as possible, the objectives contemplated by the Parties when entering this Agreement.

15.11 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

91.

15.12 Independent Contractors. It is expressly agreed that FibroGen, on the one hand, and AstraZeneca, on the other hand, shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency. Neither FibroGen, on the one hand, nor AstraZeneca, on the other hand, shall have the authority to make any statements, representations or commitments of any kind, or to take any action that will be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such first Party.

15.13 English Language. This Agreement shall be written and executed in and all other communications under or in connection with this Agreement shall be in, the English language. Any translation into any other language shall not be an official version thereof and in the event of any conflict in interpretation between the English version and such translation, the English version shall control.

15.14 Counterparts. This Agreement may be executed in one (1) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

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.

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

2.1 AstraZeneca has zero tolerance for Bribery or corruption (i.e., improper influence).

The Company will support Employees and Third Parties who refuse requests to Give or Receive Bribes on the Company’s behalf. Employees and Third Parties will not be subject to retaliation or other adverse consequences for such refusal, even if the Company loses business as a result.

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 limits of this Policy, supporting Global Standards and Relevant Procedures.

For purposes of this Policy, supporting Global Standards and Relevant Procedures, “something of value” means any financial or non-financial benefit of any kind, including, but not limited to:

a) the Giving and Receiving of Items of Value and Hospitality (See Section 3 and the Global Standard on Items of Value and Hospitality);

b) prices, discounts and rebates for Company Products Given to Third Parties (See Section 4);

c) Contributions Given to Third Parties (See Section 5 and the Global Standard on Contributions);

d) Political Support Given to Public Officials or Political Organisations and participation in Political Activities (See Section 6);

e) payments Given to Public Officials and Public Sector Organisations (See Section 7);

f) appointments, paid and volunteer work outside of the Company or other interests associated with actual, apparent or potential Conflicts of Interest (See Section 8);

g) the venue, conduct or other arrangements made for Meetings, as well as the selection and/or support of External Stakeholders to attend Meetings or independent congresses, including professional education credits and capability-building sessions (See Section 9 and the Global Standard on Meetings);

h) the engagement of Third Parties to provide Services, including compensation and expense reimbursement (See Section 10 and the Global Standard on Engaging Third Parties); and

i) support for External Stakeholders for Non-Interventional Studies and Investigator Sponsored Studies (See Sections 13 and 14).

2.3 You must not Give or Receive something of value that is intended or could be seen as improper influence.

If you 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. Also, see paragraph 1.18 of the Global Standard on Items of Value and Hospitality for requirements regarding exceptional Cultural Courtesy Gifts in the form of cash or cash equivalent.

2.5 You must not Give a Bribe.

Give means to directly or indirectly offer, promise or give, or to authorise such actions.

You must not Give something of value to any Third Party or any fellow Employee that is intended or could be seen to:

a) influence or reward an official action or decision (e.g., by a Public Official);

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:

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 pricing model, and this documented purpose must be approved by the head of the relevant Business Unit or designee to ensure 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, the relevant Business Unit may agree upfront with the recipient organisation to conduct appropriate 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 required by Relevant Procedures. Contributions must not be Given to an organisation 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 Employee 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.

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.

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 and 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.

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 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.

Third Parties must not provide any Service on behalf of the Company, in connection with the execution 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 approval.

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 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 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:

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.

All inquiries concerning Unauthorised Company 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.

12.2 Relevant Employees (e.g., Employees in the Marketing, Medical or Sales functions) and specifically authorised Third Parties 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 Healthcare Organisations (“HCOs”) (i.e., payers) or Public Officials to support regulatory Authorisation, pricing or reimbursement 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;

c) the likelihood of receiving significant changes and comments to the proposed labeling submitted to the regulatory agency responsible for Authorisation;

d) the risks of pre-Authorisation Promotion arising from providing training on Unauthorised Company Products or Uses and/or Promotional messages; and

e) other factors deemed relevant to the particular proposed training by the Reviewer and/or contributing functions, who are evaluating the training need and the associated risks.

All Pre-Authorisation Training materials must be marked with a clear, prominent, appropriate disclaimer stating that the material is strictly for internal purposes only (e.g., “For Internal Use Only”). These materials may include information on Unauthorised Company Products or Uses or relevant disease areas, and may include relevant reprints. These materials, or the information they contain, must not be shown, discussed, or distributed outside the Company, except where an appropriate Third Party must also be trained (e.g., a contract sales force or sales force of a co-promotional partner).

After the relevant Authorisation has been obtained, information included in Pre-Authorisation Training materials that is appropriate for discussion with External Stakeholders or Patients may be included in Promotional and/or Non-Promotional Materials specifically designed and approved for those purposes.

13. NON-INTERVENTIONAL STUDIES

13.1 Non-Interventional Studies (“NISs”) must address a scientifically and medically valid question to which the Company needs the answer.

These may include: the effectiveness and/or safety of a Company Product, medical practice and drug utilisation characterisation, disease epidemiology and clinical epidemiology, burden of disease (e.g., costs and quality of life) or other Patient-reported outcomes, and compliance/adherence to a therapeutic regimen.

13.2 The Company must not be involved in the decision to place a particular Patient on a specific Company Product. That decision is made solely by the Patient’s HCP.

An NIS must not be used to induce the use or prescription of a Company Product or to train HCPs on the use of a particular therapy.

Patients must not be given a Company Product or switched to a Company Product for the purpose of taking part in the study.

13.3 NISs must be observational in nature and the collected data must undergo a formal analysis by the Company or by a Third Party on the Company’s behalf.

Additional diagnostic or monitoring procedures must not be applied to the Patients, and epidemiological methods must be used for the analysis of collected data.

13.4 See Section 2 of this Policy for further requirements on NISs. Employees must also refer to the Relevant Procedures (i.e., International Procedures) for further requirements.

All NISs must be registered and their results posted according to the requirements of the Relevant Procedures.

The decision to conduct an NIS and the selection, engagement and payment of NIS investigators must meet all of the relevant requirements of Section 10 of this Policy and the Global Standard on Engaging Third Parties.

Support for NISs may be Given by specifically authorised Third Parties on behalf of the Company according to the Relevant Procedures.

14. INVESTIGATOR SPONSORED STUDIES

14.1 The Company recognises the importance of Investigator Sponsored Studies (“ISSs”) in expanding scientific knowledge related to potential Uses of Company Products.

An ISS may be conducted with Authorised or Unauthorised Company Products or Uses.

All ISSs supported by the Company must be consistent with the research strategy for the relevant Company Product.

14.2 The Company may provide support for an ISS, but must not be considered to be the sponsor or to have any partial sponsorship role in the study in accordance with local law.

The decision to provide support for an ISS must be based on whether the study expands scientific knowledge related to potential Uses of Company Products and/or associated disease area(s) through a properly conducted independent clinical study that will result in the publication of meaningful new data.

14.3 See Section 2 of this Policy for further requirements on ISSs. Employees must also refer to the Relevant Procedures (i.e., International Procedures) for further requirements.

A contract approved through the Applicable Internal Review Procedures must be negotiated and signed by authorised representatives of the Company and the sponsor and, as applicable, the investigator, prior to study initiation.

The level of financial support that may be provided will vary among countries. It must always be consistent with Fair Market Value for the activities to be conducted as part of the clinical trial, and payments must be milestone-driven.

The Company must not provide Company Product Samples for use in ISSs.

Support for ISSs may be Given by specifically authorised Third Parties on behalf of the Company according to the Relevant Procedures.

ASTRAZENECA AND FIBROGEN COLLABORATE TO DEVELOP AND

COMMERCIALISE FG-4592, A TREATMENT FOR ANAEMIA IN

CHRONIC KIDNEY DISEASE AND END-STAGE RENAL DISEASE

Collaboration to include US, China and selected other markets

31 July 2013

AstraZeneca and FibroGen today announced that they have entered into a strategic collaboration to develop and commercialise FG-4592, a first-in-class oral compound in late stage development for the treatment of anaemia associated with chronic kidney disease (CKD) and end-stage renal disease (ESRD).

This broad collaboration focuses on the US, China and all major markets excluding Japan, Europe, the Commonwealth of Independent States, the Middle East and South Africa, which are covered by an existing agreement between FibroGen and Astellas Pharma Inc. The AstraZeneca-FibroGen joint effort will be focused on the development of FG-4592 to treat anaemia in CKD and ESRD, and may be extended to other anaemia indications.

FG-4592 is a small molecule inhibitor of hypoxia-inducible factor (HIF) prolyl hydroxylase. HIF is a protein that responds to oxygen changes in the cellular environment and meets the body’s demands for oxygen by inducing erythropoiesis, the process by which red blood cells are produced. FG-4592 has the potential to address the considerable unmet medical need for an effective treatment for anaemia that offers the convenience of oral administration and an improved safety profile as compared to current standards of care. At present, treatment options involve a combination of injectable erythropoiesis-stimulating agents (ESAs) and iron supplements. FG-4592 works through the body’s natural oxygen-sensing and response system to help produce red blood cells. This can be compared to the body’s natural response to conditions at high altitude, where oxygen levels are low, which is to produce more red blood cells.

In Phase II clinical studies, FG-4592 met its primary objective of demonstrating anaemia correction in treatment-naïve CKD patients not on dialysis as well as maintenance of haemoglobin levels and anaemia correction in patients on dialysis. FG-4592 has demonstrated this efficacy combined with an acceptable safety profile in clinical trials, and has been shown to achieve anaemia correction in the absence of intravenous iron supplementation.

The companies plan to undertake an extensive FG-4592 phase III development programme for the US, and to initiate phase III trials in China, with anticipated regulatory filings in China in 2015 and in the US in 2017.

AstraZeneca will pay FibroGen committed upfront and subsequent non-contingent payments totalling $350 million, as well as potential future development related milestone payments of up to $465 million, and potential future sales related milestone payments in addition to tiered royalty payments on future sales on FG-4592 in the low 20% range. Additional development milestones will be payable for any subsequent indications which the companies choose to pursue.

AstraZeneca will be responsible for the US commercialisation of FG-4592, with FibroGen undertaking specified promotional activities in the ESRD segment in this market. The companies will also co-commercialise FG-4592 in China where FibroGen will be responsible for clinical trials, regulatory matters, manufacturing and medical affairs, and AstraZeneca will oversee promotional activities and commercial distribution.

Pascal Soriot, Chief Executive Officer, AstraZeneca, said: “Our collaboration with FibroGen on FG-4592 is an important addition to AstraZeneca’s growing late-stage portfolio in cardiovascular and metabolic disease, one of our core therapy areas. We know from our research into complications of renal disease that anaemia continues to be a challenge for patients with chronic kidney disease, due in part to the inconvenience and complexity of existing injectable and intravenous therapies and the safety concerns associated with them. The science behind this compound is compelling. Through our collaboration with FibroGen we aim to offer a first-in-class, convenient treatment option for doctors and patients.”

Xxxxxx X. Xxxx, Chief Executive Officer, FibroGen, said: “FG-4592 has the potential to offer anaemia patients an oral therapy that provides coordinated erythropoiesis, that increases natural erythropoietin within the normal physiological range, and that is effective without intravenous iron supplementation and without an increased risk for hypertension. We are especially pleased that AstraZeneca will share our commitment to making China the first-to-launch country for FG-4592 and join our effort to bring important innovation in anaemia therapy to CKD and ESRD patients in the US and other countries. This agreement secures proper development and commercialisation resources for FG-4592, and ensures US clinical trial efforts are fully funded.”

NOTES TO EDITORS

About chronic kidney disease and anaemia

Diabetes, high blood pressure, and other conditions can cause significant damage to the kidneys. If left untreated, those can result in chronic kidney disease and progress to kidney failure. Such deterioration can lead to patients needing a kidney transplant or being placed on dialysis to remove excess fluid and toxins that build up in the body. The progression of CKD also increases the prevalence of anaemia, a condition associated with having fewer of the red blood cells that carry oxygen through the body, and/or lower levels of haemoglobin, the protein that enables red blood cells to carry oxygen. As haemoglobin falls, the lower oxygen-carrying capacity of an anaemic patients’ blood results in various symptoms including fatigue, loss of energy, breathlessness, and angina. Anaemia in CKD patients has been associated with increased hospitalisation rates, increased mortality, and reduced quality of life.

CKD is a worldwide critical healthcare problem that affects millions of people and drives significant healthcare cost. In the US, prevalence of CKD has increased dramatically in the past

20 years, from 10% of the adult population (or approximately 20 million US adults) as stated in the National Health and Nutrition Evaluation Survey (NHANES) 1988-1994, to 15% (or approximately 30 million adults) in NHANES 2003-2006. In 2009, total Medicare costs for CKD patients were $34 billion. China has an estimated 125 million CKD patients, or 5 times the number of CKD patients in the US [Lancet April 2012].

About FG-4592

FG-4592 is an orally administered small molecule inhibitor of hypoxia-inducible factor (HIF) prolyl hydroxylase activity, in development for the treatment of anaemia in patients with chronic kidney disease (CKD). HIF is a protein transcription factor that induces the natural physiological response to conditions of low oxygen, “turning on” erythropoiesis (the process by which red blood cells are produced) and other protective pathways. FG-4592 has been shown to correct anaemia and maintain haemoglobin levels without the need for supplementation with intravenous iron in CKD patients not yet receiving dialysis and in end-stage renal disease patients receiving dialysis. An Independent Data Monitoring Committee has found no signals or trends to date to suggest that treatment with FG-4592 is associated with increased risk of cardiovascular events, thrombosis, or increases in blood pressure requiring initiation or intensification of antihypertensive medications.

Under a licensing agreement between FibroGen, Inc. and Astellas Pharma Inc., Astellas is developing FG-4592 for the treatment of anaemia in CKD and ESRD patients in Europe, Japan, the Commonwealth of Independent States, the Middle East, and South Africa.

About FibroGen
