If requested by SutroVax in writing (which request shall not be made prior to [***]), the Parties shall negotiate in good faith reasonable terms and conditions of an agreement for the supply by Sutro of the Products for the production of Vaccine Compositions for use in phase 3 clinical studies and for commercial purposes (Phase 3/Commercial Supply Agreement). The price for the Products Manufactured by Sutro under the Phase 3/Commercial Supply Agreement shall not exceed [***] of the Fully Burdened Manufacturing Cost thereof. If the Parties have not entered into the Phase 3/Commercial Supply Agreement within [***] after SutroVax's request to negotiate the Phase 3/Commercial Supply Agreement, upon either Party's request by written notice to the other Party the terms and conditions of the Phase 3/Commercial Supply Agreement shall be determined by binding arbitration in accordance with the procedures set forth in Section 11.4. Upon the selection of one draft Phase 3/Commercial Supply Agreement by the arbitrator pursuant to Section 11.4, unless SutroVax elects not to enter into such Phase 3/Commercial Supply

Agreement by written notice thereof to Sutro within [***] days after such selection, the Parties shall execute the definitive Phase 3/Commercial Supply Agreement selected by the arbitrator (but excluding, for clarity, any provision granting to SutroVax or its Affiliates or Sublicensees any right to obtain or use any Sutro Core Know-How); and if SutroVax elects to not enter into the Phase 3/Commercial Supply Agreement selected by the arbitrator by providing notice thereof within such [***] day period, then neither Party shall be obligated to enter into the Phase 3/Commercial Supply Agreement.

2.15 Qualification of Alternate Supplier.

2.15.1 Transfer Addendum.

(a) Transfer Addendum. Upon SutroVax' written request, the Parties agree to negotiate in good faith an addendum to this Supply Agreement setting forth the terms and conditions pursuant to which Sutro will conduct a Process Transfer to a Third Party contract manufacturer (CMO) and/or engage such CMO to establish Capacity to Manufacture Extract (as Process Transfer and Capacity are defined below), in each case for the Manufacture and supply of such Extract for SutroVax' (or its Affiliate's or SutroVax CMO's) use to manufacture Vaccine Compositions, consistent with the remainder of this Section 2.15 (such addendum, a Transfer Addendum). As requested by SutroVax, this procedure may also be used in the event that SutroVax wishes Sutro to conduct a Process Transfer to a Third Party CMO in order to establish Capacity to Manufacture Custom Reagents. In connection with such request, SutroVax shall provide to Sutro a description of the desired Process Transfer and/or Capacity, including timing and other requirements thereof. Such Transfer Addendum shall:

(i) include a plan and budget for the conduct of the Process Transfer and/or establishment of such Capacity, which shall include amounts charged by the CMO (as defined further below, the Alternate Supplier) to receive and conduct such Process Transfer and/or establish such Capacity, as well as reasonable FTE costs for Sutro personnel performing and managing technology transfer activities in accordance with the Transfer Addendum

(ii) require SutroVax to fund the costs incurred by Sutro to conduct Process Transfer and/or establish such Capacity in accordance with such budget;

(iii) provide for initiation and completion of the Process Transfer and establishment of Capacity as requested by SutroVax, to the extent possible;

(iv) to the extent requested by SutroVax, be designed to enable the Alternate Supplier to Manufacture Extract of suitable quality for use in Phase 3 clinical trials and commercialization of a Vaccine Composition at a capacity to support SutroVax' projected commercial requirements for Extract (or other capacity identified by SutroVax in connection with the negotiation of the Transfer Addendum), as requested by SutroVax;

(v) require the Parties to fully cooperate to verify that the Extract supplied by the Alternate Supplier meets the Specifications, to validate the Manufacturing process implemented at the Alternate Supplier and to qualify the Alternate Supplier, in each case to supply Extract for SutroVax' use in Phase 3 clinical trials and commercialization of a Vaccine Composition (collectively, with respect to Capacity established, Validating such Capacity);

(vi) include mechanisms for keeping SutroVax fully informed, at scheduled intervals not to exceed once per quarter, of the progress of the Process Transfer and establishing such Capacity, as applicable, including with respect to the anticipated date for qualifying the Alternate Supplier and any changes to such anticipated date;

(vii) provide a right for SutroVax to modify the timing of or terminate the Process Transfer, Capacity or specified aspects thereof on reasonable notice, subject to SutroVax' agreement to bear any resulting termination or cancellation fees charged by the Alternative Supplier; and

(viii) include a mechanism for Sutro to cooperate with SutroVax and keep SutroVax reasonably informed with respect to Sutro's negotiation of an agreement with a potential Alternate Supplier for a Process Transfer and/or establishment of Capacity, including with respect to pricing for Extract from the Alternate Supplier to Sutro and any commitments to purchase quantities of Extract from the Alternate Supplier that SutroVax would be obligated to assume (e.g., in connection with establishing Capacity), if any, and require Sutro to obtain SutroVax' approval (not to be withheld unreasonably) of the terms of such agreement prior to entering into such agreement to the extent that the terms apply to SutroVax (it being understood that Sutro may redact any terms that are not relevant to SutroVax).

(b) Scope. As used above, Process Transfer means a technology transfer of Sutro's know-how and information as is necessary or useful for the Third Party CMO to Manufacture in its own facilities Extract that meets SutroVax' requirements, including any such information and know-how as would be needed for such CMO to scale up such Manufacture to the requested commercial volumes. To establish Capacity means that the CMO would take such actions as are necessary (including validation and if necessary adapting or reserving existing facilities, establishing new facilities and/or procuring necessary equipment) to Manufacture Extract meeting SutroVax' requirements for Phase 3 and commercial supply in such quantities as SutroVax designates. It is understood that SutroVax may request that the Process Transfer and establishment of Capacity be undertaken in separate steps, for example by undertaking an initial Process Transfer to demonstrate the CMO's ability to Manufacture Extract, and then later establishing Capacity for Phase 3 and commercial supply, as requested by SutroVax in accordance with Section 2.15.1(a) (i.e., in separate requests).

(c) Selection of Alternate Supplier. The Alternate Supplier will be selected by Sutro, provided that Sutro must select an Alternate Supplier that is substantially similar to those CMOs identified on Schedule 2.15.1 hereto and provided further that SutroVax shall have the right to veto such selection based only on a genuine and material conflict of interest between SutroVax and the Alternate Supplier. Additional CMOs may be added to Schedule 2.15.1 by Sutro with SutroVax's approval (not to be withheld unreasonably).

(d) Alternate Supplier as Subcontractor. It is understood that the Alternate Supplier established under the Transfer Addendum shall operate as a subcontractor of Sutro under this Supply Agreement and the Phase 3/Commercial Supply Agreement, and as such SutroVax will order from Sutro thereunder any Extract to be Manufactured by such Alternate Supplier. Subject to the foregoing, the Transfer Addendum and the Phase 3/Commercial Supply Agreement will include reasonable and customary rights for SutroVax to conduct audits/inspections, site visits, quarterly meetings, each such audit/inspection, site visit and quarterly meeting to be coordinated by Sutro and to occur in the presence of a representative for Sutro and SutroVax, in connection with the Alternate Supplier's manufacture of Extract for supply to SutroVax. For clarity, SutroVax shall not conduct any business discussions for the supply of Extract with the Alternate Supplier in a manner that induces the Alternate Supplier to breach its agreement with Sutro. Notwithstanding the foregoing, in the event Sutro undergoes a Change of Control or Sutro permits any third party to acquire Extract directly from an Alternate Supplier established under the Transfer Addendum, then SutroVax shall thereafter have the right to establish a supply agreement with and obtain supply of Extract directly from such Alternate Supplier.

(e) Quotations. Upon SutroVax's request (which request, for clarity, may be before a request to negotiate a Transfer Addendum), Sutro shall seek quotations from one or more Third Party CMO(s) for such a Process Transfer and/or establishment of such Capacity, in each case as requested by SutroVax, and the Parties shall reasonably cooperate to establish requests for quotations for such purposes.

(f) Arbitration. If the Parties have not agreed upon a Transfer Addendum within [***] after SutroVax' request, upon SutroVax' request by written notice to Sutro, the terms and conditions of the Transfer Addendum shall be determined by binding arbitration in accordance with the procedures set forth in Section 11.4. For clarity, however, it is understood that a Transfer Addendum shall not include any provision granting to SutroVax or its Affiliates or Sublicens.ee s any right to obtain or use any Sutro Core Know-How.

2.15.2 Source of Supply. It is understood that after the Alternate Supplier is qualified, SutroVax shall have the right under this Supply Agreement and the Phase 3/Commercial Supply Agreement to specify whether Extract ordered from Sutro pursuant to this Agreement or the Phase 3/Commercial Supply Agreement will be Manufactured at Sutro's Facility or at the Alternate Supplier's facilities (and to the extent Extract from the Alternate Supplier is ordered under this Supply Agreement or the Phase 3/Commercial Supply Agreement, the facility of the Alternate Supplier shall be deemed a Facility for purposes of this Supply Agreement and the Phase 3/Commercial Supply Agreement). Notwithstanding the foregoing, to the extent the FDA and EMA have confirmed that Extract manufactured at Sutro's Facility and the Alternate Supplier's Facility are interchangeable and can be supplied from either such Facility without any additional regulatory requirements or regulatory delay with respect to the applicable Vaccine Composition, and such Extract otherwise meets SutroVax' requirements, then with SutroVax' consent (not to be withheld unreasonably) Sutro may supply Extract from either Sutro's Facility or the Alternate Supplier's Facility.

2.15.3 Price. To the extent Sutro or its Affiliate Manufactures Extract supplied to SutroVax, the Price (per unit volume or unit weight) under this Supply Agreement and the Phase 3/Commercial Supply Agreement for such Extract shall not exceed [***] of the Fully Burdened Manufacturing Costs of such Extract; and to the extent the Extract to be supplied to SutroVax is Manufactured by a Third Party (including the Alternate Supplier), the Price to be

charged to SutroVax under this Supply Agreement and the Phase 3/Commercial Supply Agreement for such Extract shall equal the amount Sutro paid such Third Party for such Extract (OOP Cost) plus an amount reasonably calculated to cover Sutro's FTE costs to procure and manage the relationship with such Third Party, such amount not to exceed [***] of the OOP Cost for such Extract. To the extent that Sutro or its Affiliate receives any portion of the amounts paid to such Third Party to Manufacture Extract (e.g., as a profit share or otherwise), the Price to be charged SutroVax shall be the lesser of i) [***], or ii) [***]; in either case, [***]. For clarity, Section 3.4 of the License Agreement shall apply with respect to the Alternate Supplier.

2.15.4 Sutro/Third Party use of Alternate Supplier. Once the Alternate Supplier is qualified pursuant to this Section 2.15, SutroVax shall have the first right (as between SutroVax and Sutro or Third Parties supplied or authorized by Sutro) to obtain Extract Manufactured by the Alternate Supplier up to the Capacity established pursuant to the Transfer Addendum for a period ending the later of [***] or [***], and provided SutroVax commits to [***] or [***].

2.16 Other Extracts. From time-to-time, subject to an agreed-upon Work Order, SutroVax may place purchase orders for quantities of research grade extract derived from strains of E. Coli other than that set forth on Schedule 1 attached hereto (each an Other Extract). Sutro shall use Commercially Reasonable Efforts to accept such purchase orders (and shall accept such purchase orders placed consistent with an agreed-upon Work Order) and manufacture and supply to SutroVax such Other Extracts. For the purpose of calculating the Price for Other Extracts in accordance with this Section, the Price will be the cost of materials and Sutro's labor at an FTE rate of [***] per year for Sutro laboratory scientists. Upon Sutro's acceptance of a purchase order for Other Extract, such Other Extract in such purchase order shall be deemed Extract for purposes of Sections 2.1, 2.2, 2.3, 2.4.1 (solely with respect to the last two sentences thereof), 2.5, 2.6, 2.7, 2.8, 2.9.1 , 3.1, 4, 5, 6, 7 and 9.

2.17 Manufacture of Custom Reagents. For clarity, SutroVax may Manufacture Custom Reagents itself or obtain supply thereof through a Third Party independent of this Supply Agreement and nothing in this Supply Agreement is intended to restrict SutroVax from doing so. Upon SutroVax's request, and subject to the remainder of the terms of this Section 2.17, Sutro shall (a) transfer to SutroVax or a contract manufacturer designated by SutroVax (which contract manufacturer is reasonably acceptable to Sutro, the approval of which shall not be unreasonably withheld, conditions or delayed by Sutro) as soon as reasonably practicable the process to Manufacture each Custom Reagent and the items of Sutro Know-How reasonably necessary for SutroVax or its designee to Manufacture each Custom Reagent, including cell lines, standard operating procedures, protocols, batch records, analytical method standard operating procedures and analytical method transfer protocols and (b) make Sutro Personnel reasonably available to SutroVax or its designee for scientific and technical explanations and on-site support that may reasonably be requested by SutroVax or its designee to Manufacture the Custom Reagents; provided however, that SutroVax shall fully reimburse Sutro for all documented time spent by Sutro's personnel to perform such transfer (on an FTE basis, each such FTE charged at an annual rate of [***]) and out-of-pocket costs incurred by Sutro in connection with all of the activities under the preceding sub-clauses (a) and (b), in accordance with a budget reasonably approved in advance by SutroVax. Upon such SutroVax request, Sutro and SutroVax shall, within [***] days, agree on a scope of work for such transfer, including

scale, timeline, estimated budget, and required materials; both parties shall use reasonable efforts to complete the transfer as soon as reasonably practical. If requested by SutroVax (including if such request is prior to agreement on a scope of work), Sutro shall promptly transfer to SutroVax or its designee the cell lines, manufacturing instructions and analytical methods used for Manufacture of each Custom Reagent. For clarity, SutroVax shall have the right to enter into an agreement directly with such designee for the Manufacture and supply of Custom Reagents directly to SutroVax, its Affiliates, and any SutroVax CMO and, upon SutroVax's request, to the extent necessary, Sutro shall authorize such designee to enter into such agreement with SutroVax and perform such activities. For further clarity, Sutro shall not be responsible for any damages resulting from delay or failure in establishing the processes for Manufacture of Custom Reagents at SutroVax's designee resulting from action or inaction on the part of the designee or to the extent beyond Sutro's control. SutroVax shall have the right to obtain from such designee such items of Sutro Know-How transferred to such designee and use such items in connection with the exercise of its rights pursuant to the License Agreement, including for the Manufacture of Custom Reagents and the management of such designee. SutroVax shall use such Sutro Know-How transferred under this Section 2.17 (to the extent it is Discloser's Information of Sutro and does not meet one or more the criteria in clause (a) through (e) of Section 10.1 of the License Agreement) only for the Manufacture of Custom Reagents or otherwise within the scope of rights and licenses granted SutroVax in the License Agreement. In case of such a transfer to SutroVax or its designee, SutroVax will share with Sutro (i) the proposed process for manufacture of Custom Reagents through a Third Party so that Sutro may provide feedback and ensure that the process and Specifications are consistent with Sutro's process, and (ii) all regulatory submissions (including DMFs with respect to Custom Reagents) at least [***] days in advance of their intended date of submission to a Regulatory Authority in the Territory, and shall take into account Sutro's feedback to ensure alignment with Sutro's regulatory submissions and Regulatory Approvals with respect to Custom Reagents. Following completion of the transfer set forth above, Sutro shall provide reasonable support for the use of Third Party Custom Reagents in conjunction with Extract supplied by or on behalf of Sutro. In addition, Extract supplied by Sutro that conforms to the Required Standards when tested with Custom Reagents supplied by Sutro but not with Custom Reagents manufactured under this Section shall be deemed to conform to the Required Standards and SutroVax may not reject such Extract as a result of such non-conformance to the Required Standards when tested with Custom Reagents. SutroVax shall not prevent Sutro from separately contracting with the contract manufacturer for Manufacture of Custom Reagents for use on its own behalf or on behalf of other third parties.

2.18 Sutro Core Know-How. Notwithstanding anything to the contrary, except as set forth in Section 15.3 of the License Agreement, in no event shall SutroVax, its Affiliates or Sublicensees have the right to access any Sutro Core Know-How (as defined in the License Agreement), whether directly from Sutro or its Affiliates or through a CMO or otherwise, and SutroVax, its Affiliates and Sublicensees shall not require, request or solicit any CMO to deliver any Sutro Core Know-How to SutroVax, its Affiliates and/or its Sublicensees, and no agreement between any CMO and Sutro, its Affiliates and Subsidiaries shall contain any provision granting to SutroVax or its Affiliates or Sublicensees any right to obtain or use any Sutro Core Know-How. Without limiting the foregoing, in the event any item of Sutro Core Know-How is delivered to SutroVax, its Affiliates and/or its Sublicensees (except as set forth in Section 15.3 of the License Agreement), SutroVax, its Affiliates and Sublicensees shall immediately return such item to Sutro. Notwithstanding the foregoing, to the extent SutroVax or any of its Affiliates

or Sublicensees is required by a Regulatory Authority (or Applicable Law) in the United States, Europe or Japan to confidentially disclose, as part of the applicable regulatory filings with respect to a Vaccine Composition, any Sutro Core Know-How (for clarity, excluding any tangible embodiments of such Sutro Core Know-How other than information and documentation), Sutro shall, upon SutroVax's written request, confidentially disclose such Sutro Core Know-How as part of the applicable regulatory filings, subject to the payment obligations set forth in Section 5.4 of the License Agreement.

2.19 Express Rights. Except as expressly set forth in this Supply Agreement, no rights or licenses are granted to SutroVax under this Supply Agreement.

2.20 Extract Requirements. SutroVax agrees to purchase all its requirements of Extract from Sutro in accordance with this Agreement, except to the extent SutroVax is allowed to purchase Extract from (a) Alternate Suppliers engaged by Sutro in accordance with Section 2.15 of this Agreement; (b) a CMO engaged or established and authorized by Sutro under Section 3.l(d) of the License Agreement; or (c) a CMO authorized by Sutro under Section 3.l(e) of the License Agreement. Manufacturing of Extracts in breach of this Section 2.20 shall be deemed a material breach of this Agreement and the License Agreement by SutroVax.

ARTICLE 3 PRICING AND PAYMENT

3.1 Invoices. Sutro shall invoice SutroVax at the time of each shipment of Product(s) for the Price for such shipment. SutroVax will pay such invoices within [***] days of receipt of invoice (including all required documentation) by SutroVax.

3.2 Prices. The Prices for the Products shall not exceed [***] of the Fully Burdened Manufacturing Costs of such Product at the time such Product is manufactured and shall be set forth in the applicable Work Order. Upon SutroVax's request from time-to-time, Sutro shall disclose to SutroVax the then- current Price for Product. The Price for the Products as of the Effective Date is set forth in Schedule 1.

3.3 Recordkeeping. During the Term and for [***] years thereafter, or for such longer period as may be required by Applicable Law, Sutro shall prepare and retain, and shall cause its subcontractors to prepare and retain, accurate books and records related to transactions made pursuant to this Supply Agreement and Prices. Such records shall be made available for reasonable review, audit and inspection upon reasonable notice and with reasonable frequency, upon SutroVax's request for the purpose of verifying Sutro's calculations of amounts due hereunder, the basis for such calculations (including Sutro's calculation of the Fully Burdened Manufacturing Costs) or payments and Sutro's compliance with the terms and conditions of this Supply Agreement. Audits and inspections may be conducted by SutroVax's own personnel or retained consultant(s), subject to the confidentiality obligations set forth in this Supply Agreement.

3.4 Taxes. The Prices are exclusive of all Taxes. SutroVax will pay all taxes and duties that are assessed by any national, federal, state or local governmental authority on SutroVax's purchase or use of the Products, including, without limitation, sales, use, excise, value-added and withholding taxes, but excluding any taxes based on Sutro's income or gross receipts (collectively, Taxes). Sutro will separately identify all such Taxes on Sutro's invoice.

ARTICLE 4 PRODUCT TESTING

4.1 Product Testing and Inspections. Each shipment of Product shall be accompanied by a certificate of analysis describing all current requirements of the Specifications and results of tests performed on such Product and a certificate of conformity certifying that the quantities of Product supplied have been Manufactured, controlled and released according to the Required Standards (COA/COC) as set forth in the applicable Quality Agreement (subject to SutroVax's conduct of the SutroVax Activity Test to confirm Extract meets the SutroVax Activity Criteria). The COA/COC acceptance criteria for each Product shall be set forth in the Specification for such Product. Two of the tests and corresponding COA/COC acceptance criteria for the Extract shall be the performance of a productivity (Activity) test of the applicable Sutro protein (the Sutro Activity Test and Sutro Activity Criteria) and the performance of a productivity (activity) test of the applicable Vaccine Composition (the SutroVax Activity Test and SutroVax Activity Criteria). Sutro shall perform the Sutro Activity Test to confirm that all shipments of Extract meet the Sutro Activity Criteria and SutroVax (or its designee) shall perform the SutroVax Activity Test to confirm that all shipments of Extract meet the SutroVax Activity Criteria. Sutro will also provide SutroVax with Material Safety Data Sheets (MSDS) or an equivalent instrument recognized by the applicable Regulatory Authority as required for the Product(s), and updates of the same as necessary.

4.2 Acceptance/Rejection of Non-Conforming Goods. SutroVax or its designee shall have a period of [***] calendar days from the date of delivery of the Product(s) in accordance with Section 2.6 and the COA/COCs or the equivalent instrument recognized by the applicable Regulatory Authority for such Product(s) (Acceptance Period), to inspect any shipment of Product(s) and conduct the SutroVax Activity Test to determine whether such shipment conforms to the Required Standards. If SutroVax determines that the Product(s) do not conform to the Required Standards, it hall notify Sutro within the Acceptance Period, and, if requested by Sutro, SutroVax shall ship a sample of such non-conforming Product(s) to Sutro at Sutro's expense. SutroVax's failure to notify Sutro of the non-conformity within the Acceptance Period will be deemed for purposes of this Supply Agreement to constitute SutroVax's acceptance of such shipment, provided, however, that such acceptance shall be subject to SutroVax's right to reject Product(s) until [***] days from the delivery date of the applicable Product, in each case, due to discovery by SutroVax or SutroVax's Affiliates or designees that the applicable Product does not conform to the Required Standards and such non-conformance could not reasonably be discovered within the Acceptance Period (Latent Defects) provided that SutroVax gives Sutro with written notice of such Latent Defect within [***] days of SutroVax or any SutroVax Affiliate or designee becoming aware of such defect.

4.3 Disputes Regarding Conformance to Required Standards. If Sutro does not agree with SutroVax's determination that Product fails to conform to the Required Standards, then Sutro shall so notify SutroVax in writing within [***] days of its receipt of SutroVax's notice of non-conformity with respect to such Product and (if requested) Product sample. Sutro and SutroVax shall use reasonable efforts to resolve such disagreement as promptly as possible.

Without limiting the foregoing, Sutro and SutroVax shall discuss in good faith mutually acceptable testing procedures pursuant to which both Sutro and SutroVax will re-test a sample of the disputed Product to determine whether such Product meets the Required Standards. Notwithstanding the foregoing, in the event that Sutro and SutroVax are unable to resolve such disagreement within [***] days of the date of the applicable rejection notice, either Party may submit a sample of the allegedly non-conforming Product for testing and a determination as to whether or not such Product conforms to the Required Standards to an independent testing organization, or to a consultant of recognized repute within the United States pharmaceutical industry, in either case mutually agreed upon by the Parties (such organization or consultant, the Laboratory), the appointment of which shall not be unreasonably withheld or delayed by either Party. The determination of the Laboratory with respect to all or part of any shipment of Product shall be final and binding upon the Parties. The fees and expenses of the Laboratory making such determination shall be borne by Sutro, in the event that the Laboratory determines that the Product was non-conforming and by SutroVax, in the event that the Laboratory determines that the Product did conform to the Required Standards.

4.4 Return and Replacement of Non-Conforming Goods. Product that is either rejected by SutroVax as not meeting the Required Standards, or that is determined by the Laboratory not to meet such Required Standards, shall, [***], be returned by SutroVax to Sutro, or destroyed pursuant to Applicable Law, at Sutro's reasonable expense. Sutro shall replace any non-conforming Product(s) within the shortest possible time. SutroVax shall have no responsibility to Sutro for the amounts invoiced for non-conforming Product(s), and shall be credited for any amounts paid, but shall pay Sutro the applicable Price for the replacement Product(s) under the terms of Section 3.1.

ARTICLE 5 INSPECTION

ARTICLE 11 DISPUTE RESOLUTION

11.1 Principal Contacts. Each Party will appoint an individual employed by it to serve as its Principal Contact for purposes of this Supply Agreement.

The two Principal Contacts shall communicate with each other regularly during the Term as the Parties may agree or as the Principal Contacts shall mutually determine to be useful.

11.2 Escalation. The Parties intend that, to the maximum extent practicable, they shall reach decisions hereunder cooperatively through discussions among the Principal Contacts and by mutual consent of the Parties. In situations in which that does not occur, disputes or differences arising out of or in connection with this Supply Agreement shall initially be referred for review by the Parties' respective Senior Managements (as defined below). Such Senior Managements shall discuss the proposed dispute or difference, and shall meet with respect thereto if either of them believes a meeting or meetings are likely to be useful. If the Senior Managements do not resolve the dispute or difference within [***] days (or such lesser or longer period as they may agree is a useful period for their discussions), then either Party may pursue its other available remedies, consistent with this Supply Agreement. As used herein, Sutro's Senior Management means its then-current CEO, and SutroVax's Senior Management means its then-current CEO. For clarity, there shall be no obligation for any Disputed Matter arising out of Section 2.14 or 2.15 to be referred to the Senior Management to review prior to such matters being resolved by arbitration pursuant to Sections 11.3 and 11.4.

11.3 Arbitration. If the Senior Managements are not able to resolve such dispute referred to them under Section 11.2 within such [***] day period, then such dispute shall be resolved by final and binding arbitration as follows: The Parties shall select a mutually agreeable arbitrator who has significant relevant experience in the subject matter of the disputed issue and no affiliation or pre-existing relationship with either Party. If the Parties cannot agree on an arbitrator within [***] days after the end of the [***] day period referred in Section 11.2 (or with respect to a Disputed Matter described in Section 11.4, after referral by a Party of such Disputed Matter to arbitration), either Party may request the Judicial and Mediation Services (JAMS) in San Francisco, CA to appoint an arbitrator on behalf of the Parties in accordance with the commercial arbitration rules of JAMS, and the proceeding shall be conducted in accordance with JAMS rules. The arbitrator may decide any issue as to whether, or as to the extent to which, any dispute is subject to the arbitration and other dispute resolution provisions in this Supply Agreement. The arbitrator must base the award on the provisions of this Supply Agreement and must render the award in a writing which must include an explanation of the reasons for such award. Judgment upon the award rendered by the arbitrator may be entered by any court having jurisdiction thereof. The arbitrator's fees and expenses shall be shared equally by the Parties, unless the arbitrator in the award assesses such fees and expenses against one of the Parties or allocates such fees and expenses other than equally between the Parties. Each Party shall bear and pay its own expenses incurred in connection with any dispute resolution under this Section 11.3. Notwithstanding the foregoing, either Party shall have the right, without waiving any right or remedy available to such Party under this Supply Agreement or otherwise, to seek and obtain from any court of competent jurisdiction any interim or provisional relief that is necessary or desirable to protect the rights or property of such Party, pending the selection of the arbitrator hereunder or pending the arbitrator's decision of the dispute subject to arbitration.

11.4 Baseball Arbitration. In the event (a) the Parties do not enter into a Phase 3/Commercial Supply Agreement as described in Section 2.14 or (b) the Parties do not enter into a Transfer Addendum as described in Section 2.15 (Disputed Matter), then upon either Party's request with respect to the Disputed Matter in clause (a) or SutroVax's request with respect to the Disputed Matter in clause (b), such Disputed Matter shall be resolved by binding arbitration conducted pursuant to Section 11.3, except that the procedures for the conduct of such arbitration shall be as follows:

11.4.1 Each Party shall provide the arbitrator and the other Party with a written report setting forth its position with respect to the substance of such Disputed Matter and a full draft Phase 3/Commercial Supply Agreement or Transfer Addendum, as applicable, and may submit a revised report, position and draft Phase 3/Commercial Supply Agreement or Transfer Addendum, as applicable, to the arbitrator within [***] days of receiving the other Party's report and draft Phase 3/Commercial Supply Agreement or Transfer Addendum, as applicable. If so requested by the arbitrator, each Party shall make oral and/or other written submissions to the arbitrator in accordance with procedures to be established by the arbitrator; provided that other Party shall have the right to be present during any oral submissions. The arbitrator shall select one of the Party's draft Phase 3/Commercial Supply Agreement or Transfer Addendum, as applicable, as his or her decision, based on what is most reasonable and equitable to each of the Parties under the circumstances and reflective of reasonable and customary terms in the biopharmaceutical industry for agreements of this type and most closely reflects the Parties' intent as expressed in this Supply Agreement and the License Agreement, and shall not have the authority to render any substantive decision other than to so select the draft Phase 3/Commercial Supply Agreement or Transfer Addendum, as applicable, of Sutro or SutroVax (as initially submitted, or as revised in accordance with the foregoing, as applicable). For clarity, it is understood that the Parties intend the arbitration under this Section 11.4 to be a baseball arbitration type proceeding; and the arbitrator may fashion such detailed procedures as the arbitrator considers appropriate to implement this intent. Notwithstanding anything to the contrary, in no event shall the Phase 3/Commercial Supply Agreement or Transfer Addendum contain any provision granting to SutroVax or its Affiliates or Sublicensees any right to obtain or use any Sutro Core Know-How.

11.4.2 In any arbitration under this Section 11.4, the arbitrator and the Parties shall use their best efforts to resolve such Disputed Matter within [***] days after the selection of the arbitrator, or as soon thereafter as is practicable.

12.4 Neither Party may assign or transfer this Supply Agreement, including by merger, operation of law, or otherwise, without the other Party's prior written consent (which shall not be withheld unreasonably) except each Party may assign this Supply Agreement without the other Party's consent in the case of assignment or transfer to a Third Party that succeeds to all or substantially all of the assigning Party's business and assets relating to the subject matter of this Supply Agreement, whether by sale, merger, operation of law or otherwise. Any attempted assignment by a Party in violation of this Section without the written consent of the other Party will be null and void.
