A.FibroGen WFOE, a wholly-owned subsidiary of FibroGen Cayman, is a biotechnology company that has expertise in the discovery and development of various prolyl hydroxylase inhibitor compounds for the treatment of anemia. FibroGen WFOE is exclusively dedicated to addressing unmet medical needs of the Chinese population by introducing first-in-class, novel medicines that are affordable and accessible to the Chinese population. FibroGen WFOE is pursuing a Class 1.1 Innovative Drug pathway in China to develop, manufacture and commercialize such compounds in China, including FG-4592, to which FibroGen WFOE has certain intellectual property rights.

B.AstraZeneca is an enterprise with expertise in the commercialization of human therapeutic products in China and with significant sales and marketing resources on-the-ground in China.

C.To ensure that the cost-effective and effective therapies developed by FibroGen WFOE are made accessible to Chinese patients, FibroGen China entered into the Amended and Restated License, Development and Commercialization Agreement (China) dated as of October 16, 2014 (the “Original A&R Agreement”), pursuant to which FibroGen China and AstraZeneca agreed to commercialize certain therapies developed by FibroGen WFOE. Under the Original A&R Agreement, FibroGen WFOE retained the rights to the technology, and was responsible for registration, clinical trials, manufacturing and physician education with respect to the Products. FibroGen China also granted certain co-exclusive license rights to AstraZeneca with respect to such technology under the terms of the Original A&R Agreement.

If there is any infringement, threatened infringement, imminent infringement or alleged infringement of any of the FibroGen China Patents on account of a Third Party’s manufacture, use, offer for sale, or sale of a Collaboration Compound or Product in the Field in the Territory (in each case, a “Product Infringement”), then each Party shall promptly notify the other Party in writing of any such Product Infringement of which it becomes aware, and shall provide evidence in such Party’s possession demonstrating such Product Infringement.

(b)Enforcement Rights. FibroGen China 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 of the FibroGen China Patents in the Territory (and to defend any related counterclaim) and the costs and expenses shall be shared equally by the Parties. FibroGen China shall have a period of one hundred eighty (180) days after its receipt or delivery of notice and evidence pursuant to Section 9.6(a) above, to elect to enforce such FibroGen China Patent in the Territory (or to settle or otherwise secure the abatement of such Product Infringement). In the event that FibroGen China does not so elect (or settle or otherwise secure the abatement of such Product Infringement), it shall so notify AstraZeneca in writing, and AstraZeneca shall have the right to commence a suit or take action to enforce the applicable FibroGen China Patent with respect to a Product Infringement in the Field in the Territory (and to defend any related counterclaim) at AstraZeneca’s expense. The IP Committee shall take the necessary actions to ensure that AstraZeneca has proper standing to bring suit under this Section 9.6(b).

(c)Cooperation. In any action, suit or proceeding instituted under this Section 9.6, 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 proceedings 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 9.6 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).

(d)Settlement. Without the prior written consent of the other Party, neither Party shall settle any claim, suit or action that it brought under this Section 9.6 involving FibroGen China 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.

Any expenses incurred by such Party as a result of any claim, suit or action under Section 9.6(b) against any person or entity engaged in Product Infringement or any other infringement of the FibroGen China Patents shall be shared by the Parties equally under this Agreement (50%/50%); [*]. If such Party recovers monetary damages from such Third Party in such suit or action, such recovery shall be first allocated to the reimbursement of any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel) and any remaining amount shall be shared by the Parties equally (50%/50%).

(f)Other Infringements. For clarity, as between the Parties, FibroGen China shall have the sole right to enforce the FibroGen China Patents in the Territory against any infringement, imminent infringement, threatened infringement or alleged infringement that is not a Product Infringement in the Field.

(g)Patents Licensed from Third Parties. Each Party’s rights under this Section 9.6 with respect to any FibroGen China Patent licensed from a Third Party shall be subject to the rights of such Third Party to enforce such FibroGen China Patent and/or defend against any claims that such FibroGen China Patent is invalid or unenforceable.

(h)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.

(i)Defense of FibroGen China Patents. To the extent any Party receives notice by counterclaim, or otherwise, alleging the invalidity or unenforceability of any FibroGen China Patent in the Territory, it shall bring such fact to the attention of the other Party, including all relevant information related to such claim. FibroGen China shall have the sole right to defend such action, at FibroGen China’s expense, and AstraZeneca will cooperate with FibroGen China in such defense. All costs and expenses incurred in such activities shall be shared by the Parties equally (50%/50%) under this Agreement; [*]. FibroGen China shall keep AstraZeneca regularly informed of the status and progress of such efforts, and shall reasonably consider AstraZeneca’s comments on any such efforts.

9.7Third Party Patents. FibroGen China shall have the sole right and authority to initiate and/or pursue at its sole expense 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 against any Third Party Patent that relates or that may potentially relate to the manufacture, use, or sale of a HIF Compound or a Product.

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 the Territory 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 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; provided that if both Parties are named in such action, then FibroGen China shall have the first right to defend such action and the costs and expenses shall be shared by the Parties equally (50%/50%) 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.

9.9Patent Marking. FibroGen China shall, and shall require its Affiliates and Sublicensees, to mark 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.

Dispute Resolution and Governing Law

14.1Disputes. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. In the event of any disputes, controversies or differences which may arise between the Parties out of or in relation to or in connection with this Agreement (including disputes arising from the JSC that are not resolved pursuant to Section 2.2(e)), including, without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement (each, a “Dispute”), then upon the request of either Party by written notice, the dispute will be referred to the Executive Officers of each Party, who shall meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting. If the matter is not resolved within thirty (30) days following the written request for discussions, either Party may then invoke the provisions of Section 14.2. It is also the expectation of the Parties that any disputes that arise under the SHA, Supply Agreement, Commercialization License Agreement, Trademark License Agreement, and/or Commercialization Services Agreement(s) are likely to be related to (or the source of) a dispute or disagreement under this Agreement, or raise issues or facts that are substantially the same as or connected with issues or facts raised in a dispute under this Agreement (a “Connected Dispute”). Accordingly, the Parties undertake to each other that they shall not, and shall procure that their respective relevant Affiliates that are parties to the SHA, Supply Agreement, Commercialization License Agreement, Trademark License Agreement, and/or Commercialization Services Agreement(s) shall not, initiate or otherwise commence any legal proceedings under the SHA, Supply Agreement, Commercialization License Agreement, Trademark License Agreement, and/or Commercialization Services Agreement(s) and shall, instead, seek to resolve the Connected Dispute in accordance with the provisions of this Section 14.1.

14.2Arbitration. Any dispute, controversy, difference or claim which may arise between the Parties, out of or in relation to or in connection with this Agreement (including, without limitation, arising out of or relating to the validity, construction, interpretation, enforceability, breach, performance, application or termination of this Agreement) that is not resolved pursuant to Section 14.1, except for a dispute, claim or controversy under Section 14.7 or 14.8, shall be settled by binding arbitration administered by the American Arbitration Association (the “AAA”) in accordance with its Commercial Arbitration Rules (or the AAA International Arbitration Rules, if recommended under the AAA guidelines), as such rules may be modified by this Section 14.2 or otherwise by subsequent written agreement of the Parties. The arbitration shall be governed by the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16 (the “Federal Arbitration Act”), to the exclusion of any inconsistent state laws. The arbitration will be conducted in New York, New York. The number of arbitrators shall be three (3), of whom the Parties shall select

CONFIDENTIAL

one (1) each. The two arbitrators so selected will select the third and final arbitrator.

Except as required by applicable law, no Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of the arbitrator without the prior written consent of the other Party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the Parties and the arbitrator, except as required in connection with the enforcement of such award or as otherwise required by applicable law. Any judgment or award rendered by the arbitrators shall be final and binding on the Parties. The Parties agree that such judgment or award may be enforced in any court of competent jurisdiction.

14.3Governing Law. Resolution of all Disputes and any remedies relating thereto shall be governed by and construed under the substantive laws of the State of California, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

14.4Decision. The arbitrators shall issue a reasoned opinion following a full comprehensive hearing, no later than twelve (12) months following the selection of the arbitrators.

14.5Award. Any award shall be promptly paid in Dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting enforcement. If as to any issue the arbitrators should determine under the applicable law that the position taken by a Party is frivolous or otherwise irresponsible or that any wrongdoing it finds is in callous disregard of law and equity or the rights of the other Party, the arbitrators shall also be entitled to award an appropriate allocation of the adversary’s reasonable attorney fees, costs and expenses to be paid by the offending Party, the precise sums to be determined after a bill of attorney fees, expenses and costs consistent with such award has been presented following the award on the merits. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Articles 14. The award shall include interest from the date of any damages incurred for breach of the Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrators. With respect to money damages, nothing contained herein shall be construed to permit the arbitrators or any court or any other forum to award punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages. The only damages recoverable under this Agreement are compensatory damages.

14.6Injunctive Relief. Provided a Party has made a sufficient showing under the rules and standards set forth in the U.S. Federal Rules of Civil Procedure and applicable case law, the arbitrator shall have the freedom to invoke, and the Parties agree to abide by, injunctive measures after either Party submits in writing for arbitration claims requiring immediate relief. Nothing in this Articles 14 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any

70.

CONFIDENTIAL

arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.

14.8Expedited Arbitration for Disputes Related to Technical Product Failure. Disputes with respect to a Technical Product Failure that are not resolved at the JSC or by the Executive Officers within twenty (20) Business Days after referral thereto, in the case of a Technical Product Failure as defined in Section 1.143(a), or resolved by the Parties, in the case of a Technical Product Failure as defined in Section 1.143(b), shall be finally determined as set forth in this Section 14.8.

Each Party shall cooperate with the Industry Expert. The Industry Expert’s determination shall be binding, and such determination shall be given retroactive effect.

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. Any permitted successor or assignee of rights and/or obligations hereunder shall, in a writing to the other Party, expressly assume performance of such rights and/or obligations (and in any event, any Party assigning this Agreement to an Affiliate shall remain bound by the terms and conditions hereof). In the event that a Party is acquired by a Third Party (such Third Party, hereinafter referred to as an “Acquiror”), then the intellectual property of such Acquiror held or developed by such Acquiror (whether prior to or after such acquisition) shall be excluded from the FibroGen China Technology (in the case when the acquired Party is FibroGen China) and AstraZeneca Technology (in the case when the acquired Party is AstraZeneca), and such Acquiror (and Affiliates of such Acquiror which are not controlled by the acquired Party itself) shall be excluded from “Affiliate” solely for purposes of the applicable components of the foregoing intellectual property definitions, in all such cases if and only if: (a) the acquired Party remains a wholly-owned subsidiary of the Acquiror; (b) all intellectual property of the acquired Party and all research and development assets and operations of the acquired Party with respect to the Product remain with the acquired Party and are not transferred to the Acquiror or another Affiliate of the Acquiror; (c) the scientific and development activities with respect to Product of the acquired Party and the Acquiror (if any) are maintained separate and distinct, and (d) there is no exchange of confidential Information relating to Product between the acquired Party and the Acquiror. For clarity, in the event that a Party is acquired by an Acquiror and any of the criteria described in subsections (a) through (d) is not satisfied, then the intellectual property of such Acquiror shall be included within FibroGen China Technology (in the case when the acquired Party is FibroGen China) 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.

15.6Performance 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.

15.7Further 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.

15.9Limitation 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.

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

15.11No 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.

15.12Independent Contractors. It is expressly agreed that each of the FibroGen Contracting Parties, 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 China, 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.

EXHIBIT D-1

FINANCE SUBCOMMITTEE

Formation and Purpose. FibroGen China and AstraZeneca China (either itself or via its designated Affiliate) have established as of the Second A&R Agreement Effective Date a Finance Subcommittee (the “FSC”), which at all times shall consist of up to four (4) representatives from each Party (or such other number as may be mutually agreed by the Parties, provided, that each Party at all times has an equal number of representatives on the FSC). Each Party may replace its FSC representatives at any time upon written notice to the other Party. Each Party shall appoint a secretariat to the FSC who is not a member of the FSC.

The FSC shall report to the China Committee with respect to all tax, accounting and financial matters relating to the First Product in the Territory, including the Net Profit and Net Loss calculations described in this Exhibit D.

Authority and Decision Making. The FSC shall act by consensus. The representatives from each Party will have, collectively, one (1) vote on behalf of that Party. If the FSC cannot reach consensus on an issue that comes before the FSC and over which the FSC has oversight, then the Parties shall refer such matter to the China Committee for resolution in accordance with Section 2.2(e) of this Agreement.

The FSC shall have no power to amend, modify, or waive compliance with Exhibit D or this Agreement.

Meetings. The FSC shall meet at least once per Calendar Quarter during the Term unless the Parties mutually agree in writing to a different frequency for such meetings as reasonably necessary. The meeting shall be scheduled in advance of any meeting of the China Committee scheduled during the same Calendar Quarter. Not later than ten (10) Business Days, or such shorter period as may be necessary in the event of any meeting convened on an ad hoc basis, the secretariats of the FSC shall jointly prepare and circulate an agenda for such meeting. The FSC may meet in person, by videoconference or by teleconference. In person FSC meetings will be held at locations alternately selected and hosted by FibroGen China and by AstraZeneca China. The host Party shall be responsible for the costs and expenses of the FSC meetings hosted, provided that each Party will bear the expense of its respective members’ participation in FSC meetings, including travel costs. Meetings of the FSC shall be effective only if at least one (1) representative of each Party is present or participating in such meeting. The FSC secretariat of the host Party will be responsible for keeping reasonably detailed written minutes of all FSC meetings that reflect, without limitation, material decision made at such meetings. The FSC secretariat of the host Party shall send draft meeting minutes to the other Party’s FSC secretariat, and each secretariat shall seek and obtain review and approval of such minutes from its respective Party’s members of the FSC within ten (10) Business Days after each FSC meeting. Such minutes will be deemed approved unless one or more members of the FSC objects to the accuracy of such minutes within ten (10) Business Days of receipt.

CONFIDENTIAL

Specific Responsibilities. In addition to its general responsibilities, the FSC shall have the following responsibilities. For clarity, certain decisions of the China Committee are subject to approval by the JSC:

| • | Review, discuss and agree the proposed calculation of Net Profit which for clarity shall be initially prepared by FibroGen WFOE, including the calculation of any amounts to be paid by the Parties hereunder; the FSC shall prepare for the China Committee a mutually agreed calculation of Net Profit for final approval by the JSC, and any adjustment proposed to implement equal profit sharing in accordance with this Exhibit D.

| • | Review the Quarterly Statement to be prepared by FibroGen WFOE.

| • | Recommend minor amendments to implement the profit/loss sharing required by this Exhibit D, for review by the China Committee and final approval, if any, by the JSC. Such proposed amendments may comprise amendments to the payment methodology described in this Exhibit D, taking into account a Party’s then current transfer pricing policies, manufacturing plant locations, and inter-Affiliate licensing practices and policies. Any amendments mutually agreed by the FSC shall be prepared for the China Committee for approval, for final approval by the JSC; no such amendments shall be implemented unless and until finally approved by the JSC, without escalation to the Executive Officers. For clarity, no Party shall be required to make any material changes to its internal accounting and reporting systems and standards to implement any such amendments.

| • | Review significant cost and expense reconciliation questions raised between the Parties.

| • | Agree on a process to invoice taking into account Indirect Taxes requirements.

| • | Establish the process for financial detail discussions between the Parties regarding the costs and expenses charged to the profit and loss calculations for the First Product.
