To exercise either of such options, Merck shall so notify NGM, in writing, by no later than twelve (12) months prior to the expiration of the Initial Research Program Term or the First Extension Period, as the case may be, and make the extension payment set forth in Section 9.1 (the Initial Research Program Term, as may be extended by the First Extension Period and the Second Extension Period, are referred to collectively as the “Research Program Term”).

Performance. NGM shall act in good faith and use its Commercially Reasonable Efforts to perform the activities under the Research Program, using the funding provided by Merck hereunder, as set forth in Section 4.2, and with the objective of identifying multiple Collaboration Compounds and Research Program Development Candidates over the course of the Full Research Program Term for development through a POC Trial, to enable Merck to exercise the Merck Option therefor, in its sole discretion. NGM shall dedicate to the Research Program appropriate resources and allocate personnel with an appropriate level of education, experience and training in identifying, researching and developing Collaboration Targets and Collaboration Compounds in order to achieve the objectives of the Research Program efficiently and expeditiously, which resources and personnel shall be consistent with the level of funding provided by Merck.

NGM’s Responsibilities. Without limiting the foregoing, during the Full Research Program Term, NGM shall, subject to Section 4.1.7:

conduct research activities leading to the selection of Collaboration Targets, including identification, characterization and validation;

optimize proteins, peptides or antibodies against their respective Collaboration Targets to ensure that resulting Collaboration Compounds are viable candidates for future pre-clinical activities and Clinical Studies;

conduct activities related to engineering, modification, expression, production, and purification of Collaboration Compounds, including peptides, recombinant proteins and antibodies;

conduct pre-clinical activities, including pharmacodynamics, pharmacokinetic and safety assessments, and Clinical Studies, up to and including the first POC Trial for each Research Program Development Candidate chosen for advancement, as deemed necessary or desirable by NGM with input from the JRC and JEDC;

conduct process and formulation development of Research Program Development Candidates as deemed appropriate by NGM with input from the JRC and JEDC;

have the right and responsibility to manufacture, or have manufactured, Research Program Development Candidates prior to Merck’s exercise of the Merck Option with respect thereto, including all required bulk drug substance and clinical materials, consistent with NGM’s reasonable internal practices, industry standards and all Laws. NGM will conduct any POC Trial with bulk drug substance the manufacture of which shall be in accordance with all Laws including GMP, it being understood, however that such drug substance will in most cases not be the commercial formulation of such Development Compound. Notwithstanding the foregoing, any contractors that NGM intends on using for the manufacture of GMP material must be audited and approved by Merck prior to performing any Collaboration Activities;

develop biomarker and other assays it determines to be useful or desirable for the Research Program Development Candidates and/or the potential Products, as deemed appropriate by NGM with input from the JRC and JEDC;

keep Merck informed, including through regular JRC and JEDC meetings during the Full Research Program Term, of all progress being made by NGM with respect to Research Program Development Candidates, at key junctures along the development path, such as Research Program Development Candidate nomination, IND filing and the like, as well as general progress made for all other Collaboration Compounds;

[*]

be responsible for preparing and filing all regulatory filings for Research Program Development Candidates, including all INDs, up through conduct of the POC Trial, all of which shall be in the name of NGM; and

make available to Merck its reasonable requirements of Collaboration Targets and other reagents for use in its internal small molecule development activities under Article 6, if and to the extent available and in NGM’s possession.

Use of Subcontractors. NGM shall be entitled to utilize the services of any Affiliates and Third Parties to perform discrete elements of its Research Program activities; provided, however, that it shall: (i) remain at all times fully liable for its responsibilities under the Research Program and shall ensure that each Affiliate and subcontractor complies with the terms and conditions of this Agreement; and (ii) ensure that NGM is the owner of (with the unfettered right to license to Merck hereunder and without any further consideration) any intellectual property rights or materials (e.g., a cell line) developed or used by any such Affiliate or Third Party service provider. Notwithstanding the foregoing, any contractors that NGM intends on using for the manufacture of GMP material must be audited and approved by Merck prior to performing any Collaboration Activities.

[*]. In the event that NGM has exceeded the Research Funding Budget for a given Research Program Year, or it is reasonably anticipated that NGM will exceed the Research Funding Budget for a given Research Program Year, it shall notify Merck through the JRC and/or JEDC, as applicable, and where at least one Research Program Development Candidate has been nominated under the Research Program, [*], in accordance with this Section 4.1.7, [*] or [*]; provided, however, that [*], in accordance with [*] and/or [*] (subject in all cases to [*]). To the extent that [*], and [*], which will be [*], or, if [*], or [*], and [*], as and to the extent set forth in Section [*].

Licenses.

NGM hereby grants to Merck a non-exclusive, royalty-free license, under any and all Patent Rights and Know-How that are Controlled by NGM or any of its Affiliates (subject to Section 14.3), solely for Merck to conduct such activities as may be undertaken by it pursuant to Section 4.1.7 or otherwise as requested by NGM and agreed to by Merck under the Research Program during the Research Program Term and to research, Develop and use Tail Compounds/Targets during the Tail Period, in each case as and to the extent specified in this Article 4. Merck may, with NGM’s prior written consent, grant sublicenses of the license set forth in this Section 4.1.8(b) to Third Parties who are acting on Merck’s behalf in the conduct of activities under the Research Program or with respect to Tail Compounds/Targets; provided, however, that: (A) each such sublicense is in writing and is consistent with the applicable terms of this Agreement; (B) each such sublicense terminates upon the termination of this Agreement; and (C) each sublicense solely permits the use of such sublicensed Patent Rights and Know-How within the scope of the license granted by NGM pursuant to this Section 4.1.8(b). For the avoidance of doubt: (i) the license set forth in this Section 4.1.8(b) does not include any right to manufacture or sell products to Third Parties; and (ii) Merck may not use the NGM intellectual property rights licensed under this Section 4.1.8(b) other than to perform the Research Program during the Research Program Term and to research, Develop and use Tail Compounds/Targets during the Tail Period.

NGM FTEs, Merck funding of NGM FTEs and NGM’s Out-of-Pocket Expenses.

NGM FTEs. During the Full Research Program Term, NGM shall, in its sole discretion, assign the appropriate number of FTEs to conduct NGM’s activities under the Research Program and NP201 Research Collaboration; provided, however, that if NGM chooses in its discretion to provide staffing that exceeds the Research Funding Budget Merck will not be obligated to pay for those NGM FTEs that exceed such Research Funding Budget.

Minimum FTE Support. Merck will provide NGM with the Research Funding, and NGM agrees to apply at least [*] of such Research Funding during each Research Program Year to pay for costs and expenses associated with the NGM FTE’s performance of the Research Program and NP201 Research Collaboration.

FTE and External Cost Funding; Annual Budgets; True Up.

NGM shall provide to Merck, not later than [*] prior to the start of each Research Program Year, a rolling annual budget, for the subsequent two (2) Research Program Years, of its projected FTE funding requirements and projected Third Party costs (including costs for consultants) and other out-of-pocket expenses incurred by it in the conduct of the Research Program and NP201 Research Collaboration, subject to Section 4.2.4 (the “External Costs”) for each such year, with the first year’s budget of such Research Program Years constituting the fixed budget for such year (such year’s budget the “Research Funding Budget”); provided, however, that in no event shall the Research Funding Budget for any Research Program Year be in excess of the applicable cap set forth below, which such cap may only be revised upon mutual written agreement of the Parties (“Research Funding Cap”):

FUNDING YEAR

Research Program Year 1 through 5

NGM will keep true, accurate and complete records of its FTE work and External Costs incurred under the Research Program. Upon the request of Merck, NGM will permit Merck or its independent certified accountants of nationally recognized standing, to have access during ordinary business hours to such of NGM’s records as may be necessary to reasonably substantiate the accuracy of NGM’s FTE efforts under the Research Program.

During the Research Program Term, Merck shall make payments to NGM [*], in an amount equal to [*] ([*] and all such amounts, collectively, the “Research Funding”). For clarity, Research Funding shall include funding for NGM FTEs conducting all elements of the Research Program and NP201 Research Collaboration, including Early Development activities, pre-POC CMC and regulatory activities, subject to the requirements of Section 4.2.2.

Within [*] days of the end of [*], NGM shall provide to Merck an accounting of the number of FTEs actually deployed in the conduct of the Research Program and NP201 Research Collaboration during such [*], multiplied by the FTE Rate, and a determination of the variance of such actual FTE costs from the [*] Research Funding provided for such [*] by Merck (the “FTE True Up Report”), and shall provide to Merck an accounting of the amount of actual External Costs incurred by NGM during such Calendar Quarter, including appropriate supporting evidence (e.g., copies of receipts) for amounts in excess of [*], and a determination of the variance of such actually incurred External Costs from [*] provided for such [*] by Merck (the “External Costs True Up Report”). [*] Merck shall have the right to deduct such positive variance amount from the next scheduled Quarterly Research Funding amount unless the Parties had previously agreed to such positive variance prior to NGM incurring such additional costs, or, where there is no such further [*] amount owed to NGM, NGM shall repay to Merck such positive variance amount within sixty (60) days of the date of such True Up Report.

Funding of FTE’s and External Costs during the First Extension Period or the Second Extension Period shall be at such levels as is mutually agreed upon by the Parties in writing, but shall be on similar business terms and payment mechanism as described above in this Section 4.2.2. Such agreement on funding of FTE’s for the First Extension Period and Second Extension Period, as applicable, shall include a budget cap of at least [*] and no greater than [*] of the Research Funding for Research Program Year 5. NGM shall not be required to conduct any research or development activities during any such First Extension Period or Second Extension Period until such funding levels are agreed.

NGM shall apply the Research Funding it receives under this Agreement solely to carry out its activities under, and in accordance with the NP201 Research Plan or in furtherance of the Research Program, and, in each case, in accordance with the terms and conditions of this Agreement. NGM covenants that it shall not use any Research Funding obtained from Merck to fund any internal or external costs associated with its activities under any of the Existing Collaboration Agreements and/or to research or develop any Retained Compounds or Retained Targets.

External Costs. “External Costs” shall include [*] to be used solely (or if applicable to other uses, then a fair allocation of such costs) in the conduct of the Research Program or NP201 Research Collaboration; provided, however, that Merck’s approval shall be obtained in writing in advance for such External Costs that are in excess of [*] for any such [*]; provided, further, that Merck shall not be responsible for [*]. For clarity, any External Costs that are: (i) approved by Merck under this Section 4.2.4, shall be included in the Research Funding Budget and shall, accordingly, be subject to, and count against, the Research Funding Cap; or (ii) not approved by Merck under this Section 4.2.4 (as and to the extent such approval is necessary), shall not be included in the Research Funding Budget, shall not count against the Research Funding Cap and NGM shall be solely responsible for any such costs.

Expense Reduction. The Parties agree to cooperate during the Research Program Term in identifying and implementing opportunities to reduce the costs incurred in the conduct of the Research Program, including costs of equipment, consumables such as laboratory supplies and Third Party services such as toxicology, clinical studies or manufacturing services, provided such cooperation does not unduly delay or hamper NGM in the performance of its activities thereunder. These attempts may include exploration of Merck’s preferred supply arrangements, and Merck’s procurement expertise.

Records; Audits. NGM will keep, and will cause each of its Affiliates and subcontractors, as applicable, to keep, adequate books and records of accounting of all FTEs, FTE spend and out-of-pocket expenses for the Collaboration for the purpose of ensuring its compliance hereunder. For the [*] following the end of the Calendar Year to which such books and records of accounting (including those of its Affiliates, as applicable) relate will be kept at its principal place of business. At the request of Merck, NGM will permit (and procure its Affiliates, to permit) an independent certified public accounting firm of internationally recognized standing selected by Merck and reasonably acceptable to NGM to have access during normal business hours to such of the records as may be reasonably necessary to verify the accuracy of the payments due hereunder from Merck in connection with FTEs and out-of-pocket expenses for any Calendar Year ending not more than [*] following the end of any Calendar Year. Such examinations may not be conducted more than once in any Calendar Year or be repeated for any Calendar Year. The accounting firm shall disclose to Merck only whether the reports are correct or incorrect and the amount of any discrepancy. No other Confidential Information shall be provided. If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within thirty (30) days of the date of delivery of such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by Merck; provided, however, that if the overcharge by NGM exceeds [*], then NGM shall pay the fees. Upon the expiration of [*] following the end of any Calendar Year, absent willful misconduct or fraud by NGM (or its Affiliates, as applicable) the calculation of amounts payable with respect to such Calendar Year shall be binding and conclusive upon Merck, and NGM shall be released from any liability or accountability with respect to amounts payable for such Calendar Year. Merck shall treat all financial information subject to review under this Section in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with NGM obligating it to retain all such Confidential Information in confidence pursuant to such confidentiality agreement.

Potential Increases to the Research Funding Cap. In accordance with Section 4.1.7, in the event that NGM has exceeded or anticipates exceeding the Research Funding Budget for a given Research Program Year, and where at least one Research Program Development Candidate has been nominated under the Research Program, Merck shall increase the Research Funding Budget solely for the purpose of performing those IND-enabling or later staged activities for the relevant Research Program Year for all Research Program Development Candidates during such Research Program Year by up to Twenty Five Million Dollars ($25,000,000) in the aggregate; provided, however, that, such Twenty Five Million Dollar ($25,000,000) amount shall be reduced each Research Program Year by an amount equal to the value of the activities that Merck performs, if any, in accordance with Section 4.1.7 (e.g., reduced by the number of Merck FTEs engaged in such activities at the FTE Rate and reduced by out-of-pocket costs Merck incurs in connection therewith). In the event that Merck is unable or unwilling to undertake the relevant activities outlined in Section 4.1.7, such Twenty Five Million dollar ($25,000,000) amount (less any reduction in connection with Merck’s performance of activities outlined in Section 4.1.7) shall be allocated between FTE funding and the funding of External Costs as appropriate to reflect whether NGM is using its own FTEs to perform the relevant activity or a Third Party service provider; provided, however, that, for clarity, such Research Funding

Early Development Matters. The following shall pertain to NGM’s Early Development activities under the Research Program:

Reports. NGM shall provide to the JEDC reasonable progress and spending updates at each Calendar Quarter meeting of the JEDC on the status of such Early Development activities, including summaries of data, summaries of the actual and anticipated areas of spending and expenses, and the likelihood of, and timetable for, completion of such Early Development activities and advancement of Research Program Development Candidates to the next phase of Development.

Ownership of Regulatory Filings.

NGM shall own and maintain all regulatory filings for Research Program Development Candidates made by it and developed pursuant to this Agreement, including all INDs. NGM shall provide the JEDC with regular updates regarding the status of regulatory filings and correspondences for Research Program Development Candidates, and such regulatory filings and correspondences shall be reviewed by the JEDC or a working group established by such committee.

Without limiting Section 5.5, upon exercise of the Merck Option with respect to a Research Program Development Candidate, NGM shall transfer ownership of such regulatory filings for such Research Program Development Candidate, including all relevant INDs to Merck, and provide Merck with copies of or access to such INDs and other regulatory filings, and all pre-clinical and clinical data and results (including pharmacology, toxicology, formulation and stability studies).

Adverse Event Reporting. Beginning on the Effective Date and continuing until such time, if any, that Merck exercises the Merck Option with respect to a Research Program Development Candidate, NGM shall be responsible for reporting all adverse drug reaction experiences related to the clinical activities of NGM under this Agreement to the appropriate Regulatory Authorities in the countries in the Territory in which the Research Program Development Candidate is being developed, in accordance with the Laws of the relevant countries and Regulatory Authorities. Without limiting the foregoing, upon Merck’s request, NGM shall provide copies of any adverse event reports with respect to a Research Program Development Candidate and any details related thereto that Merck reasonably requests.

Research and Development during the Tail Period.

Portfolio Review. During the [*] period immediately prior to the last day of the Research Program Term (where either no extensions remain or Merck has not elected to extend the Research Program Term), Merck shall have the right to review with NGM the Collaboration Compounds then identified, and their associated Collaboration Targets, and determine if there are Collaboration Compounds for which Merck desires NGM to continue to conduct research and development, including, where successful, through POC (the “Tail Compounds/Targets”) over the ensuing three (3) years immediately following the final year of the Research Program Term (each, a “Tail Year”). Merck shall have the right to require NGM to conduct such additional research and development of such Tail Compounds/Targets, subject to the limits set forth in Section 4.4.2. Notwithstanding the foregoing, Merck may terminate the Tail Period or any particular Tail Year upon [*] written notice to NGM, in which case NGM shall be responsible, at Merck’s expense, upon Merck’s election in writing, for transitioning any Clinical Studies then-being conducted to Merck or its designee, in which event the terms and conditions (including each Party’s rights and obligations) of Sections 13.6.2(d) through (i), inclusive, shall apply to all such Tail Compounds, mutatis mutandis, subject only to transfers and the like being provided by NGM to Merck (and not by Merck to NGM), or, where Merck does not so elect to have transitioned to it any such Clinical Studies, NGM shall be responsible for an orderly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices, of any such Clinical Studies or continuing any such Clinical Studies, at its own expense, and the applicable Collaboration Compounds shall become Non-Qualifying Compounds. Where Merck assumes the conduct of such Clinical Studies but terminates Development of the applicable Collaboration Compounds prior to completion of the first POC Trial, such Collaboration Compounds shall become Non-Qualifying Compounds. Where Merck assumes the conduct of such Clinical Studies, upon completion of the first POC Trial with respect to any Tail Compound, the Merck Option would remain in effect and be exercisable as set forth in Article 5, as though NGM had conducted such POC Trial, except that no Data Package shall be due from NGM with respect to such POC Trial, and Merck shall be required to exercise the Merck Option in the same timeframe as provided in Section 5.3.1, with such [*] period commencing once Merck has available to it the same information as would have been contained in the Data Package for such POC Compound. In addition, to the extent then-ongoing, all research activities that are not Clinical Studies under the Tail Period shall terminate, effective upon such effective date of termination, and in any event Merck shall have no obligation to pay for any External Costs or such work performed by the NGM FTEs after the effective date of such termination including the Research Funding after such date with respect thereto, and the licenses and rights granted by Merck to NGM in Section 4.1.8(a) will terminate and such licenses and rights shall revert to Merck and NGM and its Affiliates and sublicensees shall have no further rights to use any such Merck IP as contemplated by Section 4.1.8(a), except to the extent needed to conduct the activities set forth above in this Section 4.4.1.

Conduct of Research and Development During Tail Period; Merck Retained Options.

NGM shall conduct the additional research and development of Tail Compounds/Targets as requested by Merck pursuant to Section 4.4.1 and in a manner consistent with this Article 4; provided, however, that Merck shall fund all such activity in the manner consistent with the funding of FTEs and out of pocket costs (including External Costs, to the extent applicable) set forth in Section 4.2, and provided, further, unless otherwise agreed to by the Parties, that such additional research and development effort and activities shall not exceed a total research and development commitment by NGM (as measured by the total annual budget for both FTEs and External Costs) in excess of: (a) for Tail Year 1, [*] of the actual amount funded for FTEs and External Costs in the last year of the

Notwithstanding Section 4.4.2(a), if, during any Tail Year or after the Tail Period, Merck desires to assume responsibility for such research and development activities with respect to one or more Tail Compounds/Targets that have yet to reach POC, Merck shall have the right to internally research and develop such Tail Compounds/Targets by providing NGM with written notice of such intent at the time of Merck’s request pursuant to Section 4.4.1 or at any time during the Tail Period; provided, that, promptly following Merck’s provision of such notice, the Parties shall agree regarding a reasonable transition plan with respect to any such Tail Compounds/Targets (which plan will account for the NGM staffing at the relevant time(s)). Any Tail Compound that undergoes a POC Trial either during the Tail Period or thereafter arising from Merck’s continued internal research and development of that Tail Compound would be subject to a Merck Option to obtain an exclusive license to such POC Compound and its Related Compounds, all in accordance with the process outlined in Article 5, as though NGM had conducted such POC Trial, except that no Data Package shall be due from NGM with respect to such POC Trial, and Merck shall be required to exercise the Merck Option in the same timeframe as provided in Section 5.3.1, with such [*] period commencing once Merck has available to it the same information as would have been contained in the Data Package for such POC Compound. In furtherance of the foregoing, NGM hereby grants to Merck an exclusive (even as to NGM, except to the extent required for NGM to perform its obligations under the Collaboration) royalty-free, sublicenseable, license, under the NGM IP, and NGM’s interest in any Collaboration Technology, to research, develop (through completion of a POC Trial), make, have made and use Tail Compounds/Targets that Merck chooses to transfer the further research and development thereof to Merck in accordance with this Section 4.4.2(b). For clarity, no post-POC development rights or commercial rights would be granted to Merck with respect to any Tail Compounds or their associated Collaboration Targets (even if Merck is internally researching and developing such Tail Compounds/Targets) unless and until Merck exercises the applicable Merck Option upon review of the data resulting therefrom. In the event Merck elects, in its sole discretion, to discontinue prior to the conduct of a POC Trial any research or development of any Tail Compounds/Targets it has elected to pursue under this Section 4.4.2(b), such Tail Compounds/Targets would thereafter be deemed to be Non-Qualifying Compounds and Non-Qualifying Targets, as applicable, and NGM would have such rights thereto as are set forth in Section 4.4.3.

Non-Qualifying Compounds/Targets. Upon expiration of the Research Program Term, if no Tail Period exists, or upon expiration of the Tail Period, Merck’s rights hereunder to all Collaboration Compounds that are not, as of such time, (1) Optioned Compounds (including, for clarity, all Related Compounds), or (2) as applicable, selected by Merck as Tail Compounds (including Research Program Development Candidates so selected) under Section 4.4.1 (the “Non-Qualifying Compounds”), and to all Collaboration Targets (other than Optioned Targets or Tail Targets) not Modulated by an Optioned

Exclusivity During Research Program Term and Tail Period. Subject to Section 14.4.2,

Research Program Term. During the Research Program Term, NGM and its Affiliates shall work exclusively with Merck on the research and development of antibodies, peptides, large molecule and small molecule compounds that Modulate Collaboration Targets in a manner that satisfies the applicable Physiologically Relevant Threshold, except for those Collaboration Targets as to which Merck has elected not to exercise the Merck Option (i.e., those targets that are deemed to be Non-Qualifying Targets), and NGM and its Affiliates shall not during the Research Program Term conduct any research, development or commercialization, whether independently or with or through an Affiliate or Third Party (including through granting a license or otherwise enabling any such activities), that is directed to any such antibody, peptide or other large molecule, or small molecule, that Modulates a Collaboration Target in a manner that satisfies the applicable Physiologically Relevant Threshold, except pursuant to this Agreement.

Tail Period. During the Tail Period, NGM and its Affiliates will work exclusively with Merck on the Tail Compounds/Targets and on the research and development of antibodies, peptides, large molecule and small molecule compounds that Modulate Tail Targets, in a manner that satisfies the applicable Physiologically Relevant Threshold, except for those Tail Targets as to which Merck has elected not to exercise the Merck Option (i.e., those targets that are deemed to be Non-Qualifying Targets), and NGM and its Affiliates shall not conduct any research, development or commercialization, whether independently or with or through an Affiliate or Third Party (including through granting a license or otherwise enabling any such activities) during the Tail Period, that is directed to any such antibody, peptide or other large molecule, or small molecule, except pursuant to this Agreement.

Principal Investigator. In the event that, during the Initial Research Program Term, the Principal Investigator is no longer in the employ of NGM (other than on account of his employment by Merck or any of its Affiliates), or is no longer directing research at NGM (a “Significant Event”), NGM shall promptly notify Merck in writing, and, no later than [*] following such

Exchange of Information. Upon the Effective Date, and on an ongoing basis during the Full Research Program Term, each Party shall promptly disclose to the other any Collaboration Inventions, and NGM shall disclose to Merck in English and in writing or in an electronic format all NGM IP not previously disclosed, and Merck shall disclose to NGM in English and in writing or in an electronic format all Merck Know-How used in the Research Program and not previously disclosed.

Existing Collaboration Agreements; Partnered Compounds and Targets.

NGM shall not use any Research Funding obtained from Merck to fund any internal or external costs associated with its activities under any of the Existing Collaboration Agreements or any other non-Collaboration activities.

NGM shall not amend any Existing Collaboration Agreement, or grant its consent (where consent may be withheld by NGM) under any Existing Collaboration Agreement, in each case, in a manner that: (i) [*] or [*]; and/or (ii) [*] that [*] the Existing Collaboration Agreement; provided, however, that nothing in the foregoing shall require that NGM breach the terms of any of such Existing Collaboration Agreements.

If during the Research Term the rights of the Third Party Partner cease to exist in their entirety under the terms of the Existing Collaboration Agreement with respect to a Partnered Compound (as a result, for example, of the expiration or termination of such agreement, or any license or option thereunder), and if as of such time [*] such Partnered Compound, then such Partnered Compound shall [*] and such compound shall [*] and [*]; provided, however, that notwithstanding Section [*]: (a) if such compound subsequently [*], then the [*] on account of the [*] shall not [*]; and (b) if such compound subsequently [*], [*] on account of the [*].

If during the Research Term the rights of the Third Party Partner cease to exist in their entirety under the terms of the Existing Collaboration Agreement with respect to Partnered Target (as a result, for example, of the expiration or termination of such agreement, or any license or option thereunder) then the applicable DNA sequence, RNA sequence, protein or peptide shall no longer thereafter be deemed a “Partnered Target” and it shall instead be made available for possible designation and investigation as a Collaboration Target under the Research Program. NGM represents and warrants that the targets set forth on Schedule 1.36 are not Partnered Targets.

In no event will the subject matter that is “Within 3^rd Party Rights” include any antibody, peptide or other large molecule or small molecule, DNA sequence or RNA sequence that is identified, discovered or reduced to practice, or otherwise researched or developed in the course of performing the Collaboration.

Data Package. Once a Collaboration Compound completes a POC Trial (and thus becomes a POC Compound), NGM shall, within [*] of such completion, provide a mutually agreed upon data package to Merck, which data package will in any event include: (i) [*]; (ii) [*]; (iii) [*]; (iv) [*]; (v) [*]; (vi) [*], in each case of (i) through (vi), inclusive, to the fullest extent reasonably possible so as to assist and enable Merck to make its decision on whether to exercise the Merck Option with respect thereto; and (vii) an executed statement affirming the representations and warranties in Sections 11.1 and 11.2 remain accurate or otherwise noting any disclosures necessary to make such representations and warranties accurate, which disclosures shall not be considered, of themselves, to be a breach of this Agreement(the “Data Package”). NGM shall, during the Option Period for such POC Compound and, as requested by Merck, meet with Merck to discuss such Data Package and any questions of Merck with respect thereto, including providing Merck with such additional information to assist with interpretation of the Data Package as Merck may reasonably request.

Grant of Merck Options.

Grant of Rights. NGM hereby grants to Merck the exclusive right, exercisable at Merck’s sole discretion, to elect to obtain the exclusive worldwide license set forth in Section 5.4 with respect to each POC Compound that has been the subject of completed a POC Trial, and its Related Compounds (which are, collectively, a set of Option Subject Compounds), under the terms and conditions set forth in this Agreement (each such right to elect, a “Merck Option” as to the applicable set of Option Subject Compounds). Each such POC Compound together with its associated Related Compounds are collectively referred to as one set of Optioned Subject Compounds, all of which are included within and subject to a single Merck Option, which option may be exercised by Merck (as provided in Section 5.3) at one time as to all such compounds in the set. For clarity, the exercise by Merck of a Merck Option with respect to a given set of Optioned Subject Compounds shall be specific to that particular set of Optioned Subject Compounds only and results in the grant to Merck of the exclusive, worldwide license, under Section 5.4.1, to research (as described in Section 5.4.1), Develop, manufacture, use and Commercialize any Product that incorporates any of such Optioned Subject Compounds. Any additional Collaboration Compounds that are developed subsequently (or in tandem) by NGM against the same Collaboration Target (other than the associated Related Compounds to a given POC Compound), but that belong to a different Modulation Category than such Optioned Compounds, and which progress to become a POC Compound that has been the subject of a completed POC Trial, shall be the subject of a separate and distinct Merck Option, which is then subject to separate exercise by Merck (as provided in Section 5.3).

Pursuit of Related Compounds. Upon exercise of a Merck Option to a POC Compound for a particular set of Option Subject Compounds, Merck shall also have the license set forth in Section 5.4.1 to research (as described in Section 5.4.1), Develop, manufacture, use and Commercialize the Related Compounds associated with such POC Compound.

Exclusivity. During the Full Research Program Term, NGM will not grant to any Third Party rights to any NGM (or its Affiliates) intellectual property that are inconsistent with or in way limit or restrict the options granted or the grant of the licenses resulting from the exercise of the Merck Options to Merck hereunder. For the avoidance of doubt, the Parties understand and agree that the Merck Option rights, as described herein, shall be exclusive options over the POC Compound that is the subject of a given Early Development program, and its Related Compounds, and unless and until such time (if any) as Merck declines to exercise or permits to lapse its pending or outstanding Merck Option rights with respect to any such POC Compound and Related Compounds, NGM shall not have the right to offer or negotiate with any Third Party with respect to the grant to such Third Party of any right or license or other encumbrance of any kind with respect to the NGM IP or NGM’s interest in the Collaboration Technology in or to any of such compounds in the Field in the Territory (including intellectual property rights covering or claiming such compounds).

Exercise of Merck Option. 

Option Period, Option Exercise. Merck may exercise a Merck Option by delivery to NGM of written notice of exercise, not later than [*] after receipt of the complete Data Package from NGM with respect to that Option Subject Compound, specifying the POC Compound as to which the Merck Option is being exercised. The [*] period during which the Merck Option must be exercised, as set forth herein, shall be referred to in this Agreement as the “Option Period.” The Parties shall comply with Section 16.17.2 with respect to any Antitrust Approvals that may be necessary in connection with the exercise of a Merck Option; such compliance shall not extend the period for Merck to give notice of its desire to exercise the Merck Option but it may delay the effectiveness of such exercise. Upon exercise of a particular Merck Option, all Option Subject Compounds that are the subject of such Merck Option (i.e., the POC Compound that is the subject of such Merck Option together with all its associated Related Compounds, whether identified or discovered before or after such Option Exercise) automatically become Optioned Compounds.

Refused Candidates. If Merck does not exercise its Merck Option with respect to a particular set of Option Subject Compounds within the applicable Option Period, subject to Section 5.3.3, then the Merck Option as to all compounds in such set of Option Subject Compounds shall expire and such compounds shall thereafter be “Refused Candidates”, and NGM will thereafter be free to develop and commercialize, subject to Section 5.3.3, all such Refused Candidates (i.e., the POC Compound that was the subject of such Merck Option and all of its associated Related Compounds), alone or with an Affiliate or Third Party, at its sole expense (as between the Parties), free of any obligation to Merck hereunder (except for royalties under Section 9.7 (subject to Section 4.8.3)).

Technical Issues and Revival of Merck Option. If Merck does not exercise its Merck Option with respect to a particular POC Compound due to the fact that, although such POC Compound completed the POC Trial, there existed Technical Issues, then Merck shall inform NGM in writing of such Technical Issues and, thereafter, if during the Full Research Program Term NGM elects to pursue (including resulting from discussions at the JRC) and completes another POC Trial with respect to such POC Compound, or completes a POC Trial with respect to a Related Compound to such failed POC Compound, or if such POC Compound or any such Related Compound is deemed to be a Tail Compound, then the Merck Option shall again be in full force and effect with respect to such POC Compound and/or Related Compound (and its Related Compounds), upon delivery of the Data Package, as set forth in Section 5.1. As used herein, “Technical Issues” means it is Merck’s reasonable belief that the advancement of the POC Compound would not be warranted for technical, safety or efficacy reasons, including [*] or [*].

Exercise following Expiration of the Research Term or Tail Period. If upon the expiration of the Full Research Program Term, a Merck Option or any POC Trial is pending, Merck shall have the full [*] time period to exercise such Merck Option.

Merck. NGM understands and acknowledges that Merck does not seek to launch or continuously market and/or sell its products in each and every country of the Territory and may not launch or continuously market and/or sell to Develop and/or Commercialize Products in every country of the Territory; provided, however, that Merck shall use Commercially Reasonable Efforts during the Term to seek Marketing Authorization for [*] and to Commercialize [*] following receipt of Marketing Authorization of such Product [*], including the Co-Detailing of each NGM Optioned Product [*] in the Co-Detailing Territory with NGM as and to the extent NGM exercises its Co-Detailing Option and in accordance with the terms of the Co-Detailing Agreement. NGM acknowledges that Merck’s obligations pursuant to this Section 7.4.1 may be satisfied by in whole or in part by Related Parties or permitted assignees.

NGM. If and to the extent NGM exercises its Co-Detailing Option with respect to an NGM Optioned Product, NGM shall [*] conduct such Co-Detailing, in accordance with this Agreement and the Co-Detailing Agreement.

NGM ANS Option. On a Product-by-Product basis (to the extent applicable), the following shall apply:

Generally; Projected Budgets and Plans. Not later than six (6) months prior to the anticipated first dosing of the first patient in the first Phase 3 Clinical Trial for such Product, Merck shall provide to NGM: (a) an initial Product Development Plan and Budget; and (b) an initial Global Commercialization Plan, to the extent developed at such time (but, in any event including a high level launch plan and associated budget for estimated Allowable Expenses of such Product through the second year post launch). NGM shall have the right to review and comment upon such initial plans and budgets, which Merck may update at its discretion based on such feedback, and NGM shall have the option (the “NGM ANS Option”), subject to Section 7.5.6, upon written notice delivered within sixty (60) days following receipt of the final iteration of such then current plans and budgets, which Merck shall identify as such when delivered to NGM (the “Baseline Projected Plans and Budgets”), to elect to co-fund a portion, to be no less than twenty-five percent (25%) and no greater than fifty percent (50%), of the worldwide

Advanced Amounts. If NGM elects to exercise the NGM ANS Option, then, notwithstanding Section 7.5.1, and regardless of the level of NGM ANS Allocation elected by NGM, Merck would advance to NGM and/or absorb on behalf of NGM an amount equal to twenty-five percent (25%) of the total of the Development Costs and Allowable Expenses (the “Advanced Amounts”), which would be carried forward and recouped by Merck out of NGM’s share of future Adjusted Net Sales from such Product as well as NGM’s share of future Adjusted Net Sales from any and all other Products as to which NGM has exercised the NGM ANS Option; provided, however, that such Advanced Amounts are subject to an aggregate cap of Five Hundred Million Dollars ($500,000,000) across all NGM Optioned Products, unless otherwise agreed by the Parties. All Advanced Amounts shall be subject to an interest rate of eight percent (8%), compounded annually, and such accrued interest shall be considered part of the “Advanced Amounts” for purposes of this Agreement, except that such interest amounts shall not be included when determining whether the Advanced Amount cap set forth in the foregoing sentence has been met. Should NGM exercise the NGM ANS Option and elect an NGM ANS Allocation that is more than twenty-five percent (25%) (such amount over twenty-five percent (25%), the “Self-Funded Allocation Amount”), NGM would be solely responsible for funding such Self-Funded Allocation Amount of Development Costs and Allowable Expenses, as applicable. For example, if NGM exercises the NGM ANS Option and elects an NGM ANS Allocation Amount of forty percent (40%), Merck would advance and/or absorb an amount equal to twenty-five percent (25%) and NGM would fund directly fifteen percent (15%) of the total Development Costs and Allowable Expenses for such NGM Optioned Product. NGM would have the right to prepay any Advanced Amounts at any time, including prior to First Commercial Sale of the applicable NGM Optioned Product.

Opting-In to Amended Development Plans and Budgets over the Baseline.

Merck has the right to update the Baseline Projected Plans and Budgets in its discretion, provided that such update shall be discussed and reviewed at the next occurring JLDC (with respect to the Product Development Plan and Budget) and/or JCC (with respect to the Global Commercialization Plan) meeting, as appropriate. In the event that the Development Costs or Allowable Expenses associated with such amended Product Development Plan and Budget and/or Global Commercialization Plan are more than [*] over the amount set forth in the Baseline Projected Plans and Budget or any then-current Revised Baseline Plans and Budget (such overage amount, the “Baseline Budget Overage”), following such discussion at such committee (and regardless of whether NGM’s

In the event that there are Unpaid Costs associated with a given NGM Optioned Product, the NGM ANS Allocation for such NGM Optioned Product (and NGM’s share of Development Costs and Allowable Expenses going forward thereafter) shall be reduced at the time of First Commercial Sale, and thereafter once per Calendar Year on or about the anniversary of the Effective Date, by replacing the NGM ANS Allocation with [*], where:

[*]; and

[*];

Payment of Development Costs. In the event NGM exercises the NGM ANS Option with respect to a given Product, within [*] days following the end of each Calendar Quarter during the Term, Merck shall deliver to NGM a written report (each, a “Development Costs Report”) setting forth in detail, with supporting documentation for out of pocket costs in excess of [*], the Development Costs incurred by it (or its Affiliates) in such Calendar Quarter with respect to such NGM Optioned Product, by activity. The Development Costs Report shall also include any Development Costs incurred by Merck (or its Affiliates) in any of the preceding Calendar Quarters that were not previously included and accounted for in a prior Development Costs Reports. To the extent there are any applicable Self-Funded Allocation Amounts, NGM shall pay to Merck its share, based upon the NGM ANS Allocation, of undisputed Development Costs within [*] days of its receipt of the Development Costs Report, subject to Section 7.5.3 and Section 7.5.5.

Sharing of Adjusted Net Sales.

In the event NGM exercises the NGM ANS Option with respect to a given Product, NGM shall receive an amount equal to the NGM ANS Allocation of all Adjusted Net Sales, subject to the calculations described in this Section 7.5.5 to account for Advanced Amounts, the unpaid Self-Funded Allocation Amounts of any Development Costs owed pursuant to Section 7.5.4, if any (“Outstanding Development Payments”), and the Allowable Expenses incurred by both Parties.

Within thirty (30) days after the end of each Calendar Quarter, each Party shall submit to the other Party a statement setting forth the Allowable Expenses, if any, it (or its Affiliates) incurred in such Calendar Quarter in connection with such NGM Optioned Product, or any Allowable Expenses incurred by such Party (or its Affiliates) in any of the preceding Calendar Quarters that were not previously included and accounted for in a prior Allowable Expense statement.

Commencing with the First Commercial Sale of any such NGM Optioned Product, in each Calendar Quarter Merck shall notify NGM of any negative Adjusted Net Sales within forty-five (45) days after the end of such Calendar Quarter and: (i) if the Allowable Expenses incurred by NGM for such Calendar Quarter in connection with such NGM Optioned Product are less than its share of such negative Adjusted Net Sales in connection with such NGM Optioned Product, NGM shall pay the difference between the Allowable Expenses incurred by NGM and the NGM ANS Allocation of such negative Adjusted Net Sales within sixty (60) days after the end of such Calendar Quarter; provided, however, that to the extent NGM has not used up the entirety of the Advanced Amounts available to it, then the amounts under this clause (c) can count as part of the Advanced Amounts, if any (the aggregate of all such Advanced Amounts, including the amounts pursuant to this clause (c) and the Advanced Amounts advanced and/or absorbed by Merck under Section 7.5.2 in the context of Development Costs, the “Total Deferred Costs”); and (ii) if the Allowable Expenses incurred by NGM for such Calendar Quarter in connection with such NGM Optioned Product exceed its share of negative Adjusted Net Sales, Merck shall pay the difference between Merck’s share of the Allowable Expenses incurred by NGM and the NGM ANS Allocation of such negative Adjusted Net Sales, less any Outstanding Development Payments, within sixty (60) days after the end of such Calendar Quarter.

For each Calendar Quarter in which Adjusted Net Sales in connection with such NGM Optioned Product is positive, Merck shall pay NGM the NGM ANS Allocation of such amounts plus Merck’s share of the Allowable Expenses incurred by NGM in such Calendar Quarter to the extent not covered by the positive portion of the NGM ANS Allocation, less deduction for any Total Deferred Costs and/or Outstanding Development Payments, to NGM within sixty (60) days after the end of such Calendar Quarter. Sharing of Adjusted Net Sales shall extend under this Agreement for so long as such NGM Optioned Product is sold in the Territory, whether by Merck, its Affiliates, sublicensees or successors in interest.

NGM ANS Allocation and Option Cap. Notwithstanding the foregoing, or anything to the contrary herein, NGM’s right to exercise the NGM ANS Option shall be limited as set forth in this Section 7.5.6. If, at the point in time when the NGM ANS Option becomes exercisable under Section 7.5.1 with respect to a particular Product, the sum of: (a) the Self-Funded Allocation Amounts actually incurred by NGM across all NGM Optioned Products as of such time; plus (b) the projected Self-Funded Allocation Amounts set forth in the Baseline Projected Plans and Budgets or the then-current Revised Baseline Projected Plans and Budgets, as the case may be, for NGM Optioned Products; plus (c) the Self-Funded Allocation Amount that NGM desires to elect with respect to such Product as set forth in the Baseline Projected Plans and Budgets for such Product as to which the NGM ANS Option has become exercisable, equal more than a total of: (x) One Billion Dollars ($1,000,000,000) if Merck has not exercised either of its options under Section 4.1.3 with respect to the First Extension Period and the Second Extension Period; or (y) One Billion Four Hundred Million ($1,400,000,000) if Merck has exercised its option under Section 4.1.3 with respect to the First Extension Period but not with respect to the Second Extension Period; or (z) One Billion Eight Hundred Million ($1,800,000,000) if Merck has exercised both its options under Section 4.1.3 with respect to both the First Extension Period and to the Second Extension Period (as applicable, the “NGM ANS Option Cap”), then NGM shall not have the right to exercise the NGM ANS Option with respect to such Product (or any Products thereafter unless and until, as determined at the time any subsequent NGM ANS Option shall have otherwise become exercisable, the sum of the amounts set forth in items (a), (b) and (c) above do not equal or exceed the NGM ANS Option Cap). With respect to any Product(s) as to which NGM is unable to exercise the NGM ANS Option pursuant to this Section 7.5.6, such Products would be subject to the payment by Merck of the milestones and royalties set forth in Article 9. For clarity, with respect to any NGM Optioned Products existing as of the time that the NGM ANS Option Cap is reached, NGM shall have the right to continue sharing in Development Costs, Allowable Expenses and Adjusted Net Sales with respect to such NGM Optioned Products in accordance with the NGM ANS Allocation applicable to each such NGM Optioned Product at such time, regardless of the actual Self-Funded Allocation Amounts actually incurred by NGM in connection therewith.

Commercialization Plans for NGM Optioned Products.

Initial Global Commercialization Plan. For each NGM Optioned Product, an initial Global Commercialization Plan shall be prepared by Merck and submitted to the JCC for review and approval no later than [*] days prior to [*].

Updated Global Commercialization Plan. Not later than [*] of each Calendar Year, Merck shall submit to the JCC for review and approval an updated Global Commercialization Plan for the following Calendar Year, which the JCC shall approve no later than [*] of such Calendar Year and attach to the minutes of the meeting of the JCC at which such Global Commercialization Plan or any amendment, modification or update is approved by the JCC. The Global Commercialization Plan will also include an estimated budget detailing the estimated Allowable Expenses for the Product in the Territory for such Calendar Year.

Merck Control. For clarity, pursuant to Section 2.10.8, Merck shall have final decision-making authority regarding any disputes in the JCC with respect to the Global Commercialization Plan, provided, however, that Merck will consider in good faith any issues or comments provided by NGM with respect to the Global Commercialization Plan at the JCC meeting at which such plan is reviewed.

Commercialization Responsibilities for NGM Optioned Products. Subject to NGM’s rights in the event of exercise of its Co-Detailing Option and as specified in the Co-Detailing Agreement, and consistent with the Global Commercialization Plan, Merck will be solely responsible for all strategic and tactical planning and execution of Commercialization of NGM Optioned Products in the Territory, including the conduct of all pre-marketing, marketing, promotion, sales, distribution, import and export activities (including securing reimbursement, sales and marketing and conducting any post-marketing trials or post-marketing safety surveillance or maintaining databases).

Merck shall have all rights to determine pricing, reimbursement, discounting and other aspects of the sales of NGM Optioned Products in the Territory, at its sole discretion.

NGM’s representatives on the JCC shall receive a copy of the Global Commercialization Plan in connection with their participation in the JCC and in sufficient time to review such plan prior to the JCC meeting to approve such plan.

Merck shall book all sales of the NGM Optioned Product in the Territory.

Unless and until NGM elects to exercise its Co-Detailing Option, Merck shall, as between the Parties, be solely responsible for the promotion and detailing of the NGM Product in the Co-Detailing Territory. At all times, as between the Parties, Merck shall be responsible for all other aspects of the Commercialization of the NGM Optioned Product in the Co-Detailing Territory.

Without limiting the foregoing, Merck shall be responsible, as between the Parties, for the conduct of all sales, distribution, import and export activities for NGM Optioned Products (including securing reimbursement, and conducting any post-marketing trials or post-marketing safety surveillance, or maintaining databases).

Merck shall ensure that the plans and reports and information prepared by Merck for consideration and comment by the JCC are sufficiently detailed in order to enable NGM, acting reasonably, to provide meaningful input with respect thereto.

Co-Detailing Option.

Overview. Subject to the terms and conditions of this Agreement and as specifically set forth in this Section 7.8, NGM (itself or through its Affiliate) shall have the option to Co-Detail the Product with Merck in the Co-Detailing Territory following First Commercial Sale of the Product in the Co-Detailing Territory. Such Co-Detailing shall be conducted pursuant to the Co-Detailing Agreement, to be entered into by the Parties as set forth in Section 7.8.4.

Grant of Option. NGM, either itself or through an Affiliate, shall have the option to Co-Detail each NGM Optioned Product through its own sales force in the Co-Detailing Territory in accordance with this Section 7.8.2 (the “Co-Detailing Option”) and the Co-Detailing Agreement. Upon exercise by NGM, NGM may elect to provide up to twenty-five percent (25%) of the total requisite details for the NGM Optioned Product in the Co-Detailing Territory, as further set forth in Schedule 7.8.4; provided, however, that, in any event, NGM shall provide no less than [*] representatives. The term of such Co-Detailing shall extend for so long as Merck is actively detailing the NGM Optioned Product in the Co-Detailing Territory and the Co-Detailing Agreement remains in effect.

Exercise of the Co-Detailing Option. NGM may exercise the Co-Detailing Option, on an NGM Optioned Product-by-NGM Optioned Product basis, at its sole discretion, by written notice given to Merck within [*] following [*] with respect to such NGM Optioned Product. To better enable NGM to determine whether or not to exercise the Co-Detailing Option with respect to a given NGM Optioned Product, no later than [*] following [*] with respect to such NGM Optioned Product for such NGM Optioned Product in the Co-Detailing Territory, Merck shall provide to NGM (including through meetings of the JLDC and/or JCC, as and to the extent applicable), Merck’s non-binding projected Allowable Expenses, including Selling Expenses, and associated initial Target Call List (as defined and described in Schedule 7.8.4) for such NGM Optioned Product through the second year post launch.

Negotiation, Execution and Delivery of Co-Detailing Agreement. On an NGM Optioned Product-by NGM Optioned Product basis, promptly following exercise by NGM of its Co-Detailing Option with respect to such NGM Optioned Product, the Parties shall commence the negotiation in good faith of an agreement containing the complete terms and conditions of such Co-Detailing based upon the terms and conditions specified in this Section 7.8.4 and Schedule 7.8.4 and other customary and appropriate terms and conditions, and enter into a mutually acceptable definitive written agreement therefor (each a, and collectively the, “Co-Detailing Agreement”). The Parties shall negotiate each Co-Detailing Agreement in good faith and with sufficient diligence as is required to execute and deliver such Co-Detailing Agreement no later than [*] after notice of exercise of the applicable Co-Detailing Option. In the event the Parties fail to execute and deliver such Co-Detailing Agreement prior to the expiration of such [*] period, the [*] of Merck (or the equivalent position) and the Chief Executive Officer (or his designee) of NGM shall meet and negotiate such Co-Detailing Agreement in good faith. For the avoidance of doubt, the inability of the Parties to execute and deliver such Co-Detailing Agreement prior to the expiration of such [*] period shall not cause NGM to lose the applicable Co-Detailing Option; provided, however, that, [*] or [*]. For clarity, nothing in this Section 7.8.4 shall limit the ability of the Parties to negotiate the terms and conditions of the Co-Detailing Agreement at any time, including prior to NGM’s exercise of a Co-Detailing Option; provided, however, that, the Parties shall not execute, and NGM shall have no Detailing rights, until such time as NGM exercises a Co-Detailing Option.

Co-Detailing Costs. Each Party will bear the Selling Expenses it incurs in connection with its own field sales force, which such Selling Expenses shall be Allowable Expenses in the calculation of Adjusted Net Sales.

Other Commercialization Activities. At all times, as between the Parties, Merck shall be the responsible Party for all aspects of the Commercialization of the NGM Optioned Product in the Co-Detailing Territory other than Co-Detailing.

Records and Inspection Rights.

NGM shall not make any payment, either directly or indirectly, of money or other assets (hereinafter collectively referred as a “Payment”), to government or political party officials, officials of international public organizations, candidates for public office or representatives of other businesses or persons acting on behalf of any of the foregoing (hereinafter collectively referred as “Officials”) where such Payment would constitute violation of any law. In addition regardless of legality, NGM shall not make any Payment either directly or indirectly to Officials if such Payment is for the purpose of influencing decisions or actions with respect to the subject matter of this Agreement or any other aspect of NGM’s business.

NGM certifies to Merck that as of the date of this Agreement NGM has screened itself, and its officers and directors, against the Exclusions Lists and it has informed Merck whether NGM or any of its officers of directs has been in Violation. After the execution of this Agreement, NGM shall notify Merck in writing immediately if any such Violation occurs or comes to its attention.

Each Party acknowledges that no employee of the other Party or its Affiliates shall have authority to give any direction, either written or oral, relating to the making of any commitment by such Party or its agents to any Third Party in violation of terms of this or any other provisions of this Agreement.

Each Party shall hold in confidence all data that identifies or could be used to identify an individual (“Personal Data”), except as required or permitted under this Agreement, or to the extent necessary to be disclosed to Regulatory Authority. In addition, each Party shall comply with all Laws with respect to the collection, use, storage, and disclosure of any Personal Data, including the U.S. Health Insurance Portability and Accountability Act (HIPAA) and the regulations promulgated thereunder. Each Party agrees to ensure that all appropriate technical and organization measures are taken to protect Personal Data against loss, misuse, and any unauthorized, accidental, or unlawful access, disclosure, alteration, or destruction, including without limitation, implementation and enforcement of administrative, technical, and physical security policies and procedures applicable to Personal Data. Merck and its Affiliates may use Personal Data received from NGM to create data sets that contain dates, ages, towns, cities, states and zip codes related to individuals (“Research Data Sets”), and may use and disclose the Research Data Sets, alone or in combination with data that cannot be used to identify an individual natural person (“Non-Identifiable Data”), for medical research, including research related to activities hereunder, and any filings of medical research study results with government Regulatory Authorities worldwide. Merck will: (a) not use or disclose Research Data Sets for any purpose other than as permitted by this Agreement, or as otherwise required by Law; (b) use appropriate safeguards to prevent the creation, use or disclosure of Research Data Sets other than as provided for by this Agreement; and (c) not use the Research Data Sets to identify any study subject or contact any study subject. Notwithstanding the foregoing, nothing in this Section 8.2.6 shall limit Merck’s use or disclosure of Non-Identifiable Data.

Use of Human Materials. If any human cell lines, human tissue, human clinical isolates or similar human-derived materials (“Human Materials”) have been or are to be collected by or on behalf of a Party for use in the NP201 Research Collaboration or the Research Program, the collecting or using Party, as applicable, represents and warrants: (i) that it has complied, or shall comply, with all Laws relating to the collection and/or use of the Human Materials; and (ii) that it has obtained, or shall obtain, all necessary approvals and appropriate informed consents, in writing, for the collection and/or use of such Human Materials. The collecting or using Party, as applicable, shall provide documentation of such approvals and consents upon the other Party’s request. Each Party further represents and warrants that such Human Materials collected by or on behalf of such Party may be used in the NP201 Research Collaboration or Research Program as contemplated in this Agreement without any obligations to the individuals or entities (“Providers”) who contributed the Human Materials, including any obligations of compensation to such Providers or any other Third Party for the intellectual property associated with, or use of, the Human Materials in the NP201 Research Collaboration or Research Program.

Each Party encourages the other Party to use the highest standards, such as those set forth in the Guide for the Care and Use of Laboratory Animals (NRC, 1996), for the humane handling, care and treatment of such research animals. All animals that are used in the course of the NP201 Research Collaboration or Research Program, or all products derived from those animals, such as eggs or milk, will not be used for food purposes, nor will these animals be used for commercial breeding purposes.

Product Complaints. Each Party shall be responsible for handling product complaints arising pursuant to its Development and Commercialization activities hereunder in compliance with Law. Each Party shall promptly provide the other Party with written notice of any such product complaint received by such Party, to the extent such Party deems such product complaint material.

Research Funding; Extension Payments. In consideration for NGM’s performance under the Research Program and NP201 Research Collaboration, Merck shall pay to NGM the research funding as set forth in Article 3 and Article 4. All such research funding payments shall be non-refundable (except as expressly set forth herein) and non-creditable. In the event Merck notifies NGM of its exercise of either of Merck’s options to extend the Research Program (i.e., the First Extension Period or Second Extension Period) pursuant to Section 4.1.3, then in each case, Merck shall pay to NGM an extension payment of [*] within [*] days of the applicable Merck notice of exercise.

Up-Front Fee. In consideration of NGM’s research efforts before the Effective Date, conduct of the Collaboration and the rights and licenses (including the license granted under the NP201 Program) and options thereto granted to Merck under this Agreement, Merck shall pay to NGM a non-refundable, non-creditable up-front fee in the aggregate amount of Ninety Four Million and Four Dollars ($94,000,004.00) within [*] days following the Effective Date, [*].

Equity Investment. Pursuant to and as further detailed in the Stock Purchase Agreement, Merck will make an initial equity investment, at the Closing (as defined in the Stock Purchase Agreement), of One Hundred Five Million Nine Hundred Ninety-Nine Thousand and Nine Hundred Ninety-Six Dollars ($105,999,996.00) as payment for approximately fifteen percent (15%) of the fully diluted shares outstanding in NGM, and will have certain other additional rights and obligations to purchase the capital stock of NGM. In addition, pursuant to and as further detailed in the Letter Agreement dated as of the Closing between Merck and NGM, in the event Merck exercises either of its options to extend the Research Program, then at each such exercise, Merck may elect to acquire additional equity in NGM.

Option Exercise Payment. Within thirty (30) days of each exercise by Merck of the Merck Option for an Option Subject Compound under Section 5.3, Merck shall pay to NGM a non-refundable, non-creditable option exercise payment of Twenty Million Dollars ($20,000,000.00) (each, an “Option Fee”); provided, however, that, in the event that Antitrust Approvals are required, in connection with the exercise of a particular Merck Option, in accordance with Section 16.17.2, then such payment shall not be due until the later of [*] days of such exercise or the receipt of such Antitrust Approvals; provided, further, that, if any requisite Antitrust Approval is not received or is no longer being sought, then: (a) Merck shall promptly notify NGM; (b) such Merck Option will be deemed to not have been exercised within the applicable Option Period; (c) no Option Fee will be due in connection with such Merck Option; (d) no rights or licenses will be granted pursuant to Section 5.4 in connection with such Merck Option; and (e) the relevant POC Compound and its Related Compounds shall not become Optioned Compounds but instead shall be deemed to have been rejected by Merck for a Technical Issue (regardless of how such an issue is described in Section 5.3.3) and shall be subject to Section 5.3.3. For clarity no Option Fee shall be payable with respect to any NP201 Compounds, which are subject to the exclusive license set forth in Article 3 as of the Effective Date.

Milestone Payments for all Products.

Development and Regulatory Milestones. Merck shall pay to NGM the amounts set forth below, which shall be non-refundable and non-creditable, on the first achievement by or on behalf of Merck or any Related Party of each of the following milestone events for each Program Compound (or Product containing or comprising such Program Compound, as applicable) or Small Molecule Collaboration Compound (or Small Molecule Product containing or comprising such Small Molecule Collaboration Compound, as applicable) (each, a “Milestone Product”); provided, however, that for any Milestone Product that is advanced following and on account of failure of an earlier Milestone Product (such newly advanced Milestone Product, a “Back-up Product/Compound”), Merck shall not be obligated to make milestone payment(s) to NGM with respect to the subsequent achievement by such Back-up Product/Compound of any milestone event that was previously achieved (and for which the applicable milestone payment was made to NGM) by the relevant failed Milestone Product; provided, further, that: (a) the milestone payments under this Section 9.5.1 for a Milestone Product shall be [*] for any [*] that [*]; and (b) no milestone payments shall be due under this Section 9.5.1 with respect to any Product for which NGM exercises its NGM ANS Option under Article 7:

Commercial Milestones. For each Milestone Product, Merck shall pay to NGM the non-refundable, non-creditable amounts set forth below upon the first occurrence of such Milestone Product achieving each annual aggregate worldwide Net Sales threshold set forth below; provided, however, that: (a) the milestone payments under this Section 9.5.2 shall be [*] for any [*]; and (b) no milestone payments shall be due under this Section 9.5.2 with respect to any Product for which NGM exercised its NGM ANS Option under Article 7. For clarity, each commercial milestone is payable once per financial threshold per Milestone Product, such that no more than two commercial milestones shall be paid on any Milestone Product.

Notification and Payment Upon Occurrence of Milestone Events. Merck shall notify NGM in writing within: (i) [*] days following the achievement of each development or regulatory milestone; and (ii) within [*] days following the end of the Calendar Quarter in which any commercial milestone is achieved. All development and regulatory milestone payments will be paid to NGM within [*] days of achievement of such milestone. All commercial milestones will be paid within [*] days following the end of the Calendar Quarter in which any commercial milestone is achieved. If a clinical milestone event is skipped for a particular Milestone Product, such skipped milestone is payable upon achievement of the next clinical milestone event or regulatory milestone event; provided, however, that if such clinical milestone or regulatory milestone is skipped for an Indication because such clinical milestone or regulatory milestone is not required for such Indication due to another Indication of such Milestone Product having achieved such clinical milestone or regulatory milestone, then no such payment for such skipped milestone shall be payable.

Single Payment Per Compound/Product. Notwithstanding the foregoing, if a given milestone payment for a given milestone event for an Indication is paid with respect to a given Program Compound or Small Molecule Collaboration Compound, then such milestone payment shall not be payable again with respect to any subsequent achievement of the same milestone event for the same Indication by a Product or Small Molecule Product containing or comprising such Program Compound or Small Molecule Collaboration Compound, and vice versa.

Royalties to NGM.

Royalties Payable to NGM. Subject to the terms and conditions of this Agreement, Merck shall pay to NGM tiered, non-refundable, non-creditable royalties on each Product, Program Compound (pursuant to Section 9.6.1(f)), Small Molecule Product and Small Molecule Collaboration Compound (pursuant to Section 9.6.1(f)) (each, a “Royalty Product”), calculated on a Royalty Product-by- Royalty Product and country-by-country (subject to Section 9.6.1 (c)) basis, as set forth in this Section 9.6.1:

Royalty Rates. Subject to 9.6.1(b) below, the royalty tiers below shall be on a Royalty Product-by-Royalty Product and country-by-country (subject to Section 9.6.1(c)) basis in those countries where: (i) [*] such Royalty Product is claimed in a Valid Patent Claim in such country; or (ii) such Royalty Product [*]; provided, however, that the following royalty rates shall be [*] for any [*]:

Aggregate Annual Net Sales of A Given Royalty Product in the Territory in a
Calendar Year

Royalty Rate

The portion of Net Sales less than [*]

The portion of Net Sales greater than or equal to [*] but less than [*]

The portion of Net Sales greater than or equal to [*]

Know-How Royalty. Notwithstanding the provisions of Section 9.6.1(a), in countries where: (i) the manufacture, sale or use of a Royalty Product would not infringe a Valid Patent Claim in such country; and (ii) the regulatory or market exclusivity, if any, granted by a Regulatory Authority in such country with respect to such Royalty Product has expired, Merck shall pay royalty rates that shall be set at [*] of the applicable royalty rate determined according to Section 9.6.1(a).

Determination of Royalty Tiers. Royalty tiers pursuant to Section 9.6.1(a) and 9.6.1(b) shall be calculated based on Net Sales of each Royalty Product in those countries in the Territory in which the Royalty Term remains in effect with respect to such Royalty Product and country; provided, however, that, the determination of whether the royalty shall be calculated under Section 9.6.1(a) or Section 9.6.1(b) shall be determined on a country-by-country basis. For clarity: (i) the allocation within each royalty tier between Section 9.6.1(a) and Section 9.6.1(b) shall be based on the percentage of total Net Sales that qualify for the reduced royalty rate pursuant to Section 9.6.1(b); and (ii) from and after the expiration of the Royalty Term with respect to a given Royalty Product and country, sales of such Royalty Product in such country shall no longer be included in calculating the royalty tiers or royalty payments due hereunder.

Royalty Term. Royalties on each Royalty Product at the rates set forth above shall commence upon the First Commercial Sale of such Royalty Product in a given country and shall continue on a Royalty Product-by-Royalty Product and country-by-country basis until the latest of: (a) the expiration of the last-to-expire Valid Patent Claim in such country with respect to such Royalty Product; (b) the expiration of regulatory or marketing exclusivity granted by a Regulatory Authority in such country with respect to such Royalty Product; or (c) the twelfth (12^th) anniversary of the First Commercial Sale of such Royalty Product in such country (the “Royalty Term”).

Royalty Conditions. All royalties are subject to the following conditions:

that only one royalty shall be due with respect to the same unit of Royalty Product;

that no royalties shall be due upon the sale or other transfer among Merck or its Related Parties for resale purposes, but in such cases the royalty shall be due and calculated upon Merck’s or its Related Party’s Net Sales to the first independent Third Party;

no royalties shall accrue on the sale or other disposition of Royalty Product by Merck or its Related Parties for use in a Clinical Study; and

no royalties shall accrue on the disposition of Royalty Product in reasonable quantities by Merck or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose), provided, however, that Merck and its Related Parties do not receive any financial payment for such disposition.

Royalties for Bulk Compound. In those cases in which Merck sells bulk Program Compound or Small Molecule Collaboration Compound, rather than Product or Small Molecule Product, to Third Parties, and Merck is not being paid on sales of such Products or Small Molecule Products with respect to the applicable bulk Program Compound or Small Molecule Collaboration Compound sold to such Third Party, the royalty obligations of this Section 9.6.1 shall be applicable to Net Sales of such bulk Program Compound or Small Molecule Collaboration Compound, as applicable, and the definition of Net Sales shall apply to such bulk Program Compound and Small Molecule Collaboration Compound mutatis mutandis.

Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to Royalty Product in any country in the Territory with a royalty rate lower than the royalty rate provided by Section 9.6.1(a) or Section 9.6.1(b), as applicable, then the royalty rate to be paid by Merck on Net Sales in that country under Section 9.6.1(a) or Section 9.6.1(b) shall be reduced to the rate paid by the compulsory licensee.

Third Party Patent Licenses. In the event that one or more patent licenses from other Third Parties are required by Merck or its Related Parties in order to make, have made, use, offer to sell, sell or import one or more Program Compounds, Products, Small Molecule Collaboration Compounds or Small Molecule Products, as applicable (hereinafter “Third Party Patent Licenses”), [*] of the royalties actually paid under such Third Party Patent Licenses with respect to such Royalty Product by Merck or its Related Parties for a Calendar Quarter shall be creditable over time against the royalty payments due NGM by Merck with respect to the sale of the Royalty Product incorporating such Program Compound or Small Molecule Collaboration Compound (as applicable); provided, however, that in no event shall the royalties paid by Merck to NGM for such Calendar Quarter be reduced to less than [*] of the amounts that would be owed pursuant to Section 9.6.1(a) or Section 9.6.1(b), as applicable, in the absence of such credit.

Generic Competition. On a country-by-country and Royalty Product-by- Royalty Product basis, if during a given Calendar Quarter one or more Third Parties is: (a) selling a Generic Bioequivalent Product for such Product or Generic Small Molecule Product for such Small Molecule Product, as applicable, in such country; and (b) such sales of such Generic Bioequivalent Product(s) or Generic Small Molecule Product(s), as applicable, in such country are, in the aggregate (on a unit equivalent basis), greater than [*] of the number of units of such Product or such Small Molecule Product, as applicable, sold in such country during such period, then, from and after such Calendar Quarter during which clauses (a) and (b) are satisfied, the royalties due for sales of such Product or Small Molecule Product, as applicable, in such country shall be reduced to [*] of the amount that would otherwise have been due under Section 9.6.1(a); provided, however, that such reduction shall not be cumulative with any reductions permitted under Section 9.6.1(h) above. For clarity, [*].

Royalties to Merck. Subject to Section 4.8.3 and the other terms and conditions of this Agreement, NGM shall pay to Merck certain non-refundable and non-creditable royalties calculated on a product-by-product and country-by-country basis, as set forth in this Section 9.7. NGM shall pay Merck a quarterly royalty on worldwide Net Sales of any product that incorporates or contains a Refused Candidate or a Non-Qualifying Compound, with royalty rates based on the development stage of the applicable Refused Candidate or Non-Qualifying Compound, as follows:

Stage of Development

Royalty Rate

Reports; Payment of Royalty. During the term of this Agreement following the First Commercial Sale of a Royalty Product, Merck shall furnish to NGM a quarterly written report for each Calendar Quarter showing in reasonable detail, on a Royalty Product-by-Royalty Product basis, the Net Sales of all Royalty Products subject to royalty payments sold by Merck and its Related Parties in the Territory during the reporting period and the royalties payable under this Agreement. Reports shall be due on the sixtieth (60^th) day following the close of each Calendar Quarter. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. Merck shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined.

Audits.

Upon the written request of a Party (“Auditing Party”) and not more than once in each Calendar Year, the other Party (“Auditee”) shall permit an independent certified public accounting firm of nationally recognized standing selected by the Auditing Party and reasonably acceptable to the Auditee, at the Auditing Party’s expense, to have access during normal business hours to such of the books and records of Auditee as may be reasonably necessary to verify the accuracy of the royalty reports, Adjusted Net Sales payments (including any reports or calculations relating to any NGM ANS Option exercised by NGM), or any other amounts payable hereunder for any Calendar Year ending not more than [*] prior to the date of such request. The accounting firm shall provide a written report to the Auditing Party that discloses only information necessary to verify whether the royalty reports or other financial reports furnished by the Auditee or the amount of payments by the Auditee under this Agreement are correct or incorrect, the amount of any discrepancy and basis for the accounting firm’s conclusion (if applicable) that there was a discrepancy. No other information shall be provided to NGM.

If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within thirty (30) days of the date the Auditing Party delivers to the Auditee such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by the Auditing Party; provided, however, that, if such audit uncovers an underpayment of amounts by the Auditee that exceeds [*], then the fees of such accounting firm shall be paid by the Auditee.

Merck shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to Merck, to keep and maintain records of sales made (or any other applicable financial information) pursuant to such sublicense and Merck shall use Commercially Reasonable Efforts to include in each such sublicense the sublicensee’s grant of access to such records by NGM’s independent accountant to the same extent required of Merck under this Agreement; provided, however, that if Merck cannot obtain such audit rights for NGM, then Merck shall (to the extent permitted under such sublicense) audit such sublicensee upon NGM’s reasonable request, and at NGM’s sole cost and expense, and Merck shall promptly share such audit results with NGM, including providing a copy of any audit report (subject to any applicable confidentiality provisions).

Upon the expiration of [*] following the end of any Calendar Year, the calculation of royalties or other amounts payable with respect to such Calendar Year shall be binding and conclusive upon an Auditing Party, and the Auditee and its Affiliates (in the case of Merck, its Related Parties) shall be released from any liability or accountability with respect to royalties or other applicable payments for such Calendar Year.

The Auditing Party shall treat all financial information subject to review under this Section 9.9 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the Auditee and/or its Affiliates or Related Parties, as applicable, obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

Payment Exchange Rate. All payments to be made by Merck to NGM under this Agreement shall be made in United States dollars by bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by NGM from time to time. In the case of sales outside the United States, the rate of exchange to be used in computing the monthly amount of currency equivalent in United States dollars due NGM shall be made at the monthly rate of exchange utilized by Merck in its worldwide accounting system.

Taxes.

Each Party shall be solely liable for all income and other taxes (including interest) (“Taxes”) imposed upon any payments made by the other Party (“Payer”) to such Party (“Payee”) under this Agreement (“Agreement Payments”).

If Law requires the withholding of Taxes, the Payer shall, subject to Section 9.11.3, make such withholding payments and shall subtract the amount thereof from the Agreement Payments. The Payer shall submit to the Payee appropriate proof of payment of the withheld Taxes as well as the official receipts within a reasonable period of time. The Payer shall provide the Payee reasonable assistance in order to allow the Payee to obtain the benefit of any present or future treaty against double taxation which may apply to the Agreement Payments.

The Parties agree that, as of the Execution Date, each Payer is not required by the Laws of the US to deduct or withhold taxes on the Agreement Payments. If an incremental withholding or deduction obligation arises as a result of any action by the Payer, including any assignment, sublicense, change of place of incorporation or failure to comply with Laws or filing or record retention requirements (a “Withholding Tax Action”), then the sum payable by the Payer (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the Payee receives a sum equal to the sum that it would have received had no such Withholding Tax Action occurred. Otherwise, the sum payable by the Payer (in respect of which such deduction or withholding is required to be made) shall be made to the Payee after deduction of the amount required to be so withheld or deducted.

Nondisclosure Obligation. All Information disclosed by one Party to the other Party hereunder or pursuant to the Prior CDA shall be maintained in confidence by the receiving Party and shall not be disclosed to any Third Party or used for any purpose except as set forth herein without the prior written consent of the disclosing Party, except to the extent that such Information:

is known by the receiving Party at the time of its receipt, and not through a prior disclosure by the disclosing Party, as documented by the receiving Party’s business records;

is in the public domain by use and/or publication before its receipt from the disclosing Party, or thereafter enters the public domain through no fault of the receiving Party;

is subsequently disclosed to the receiving Party by a Third Party who may lawfully do so and is not under an obligation of confidentiality to the disclosing Party;

is developed by the receiving Party independently of Information received from the disclosing Party, as documented by the receiving Party’s business records;

is disclosed to governmental or other regulatory agencies in order to obtain patents or to gain or maintain approval to conduct clinical trials or to market Products or Small Molecule Products, but such disclosure may be only to the extent reasonably necessary to obtain patents (subject to the applicable provisions of Article 12) or authorizations;

is deemed necessary by Merck to be disclosed to Related Parties, agent(s), consultant(s) and/or other Third Parties for any and all purposes Merck and its Affiliates deem necessary or advisable in the ordinary course of business in the exercise and performance of its rights and obligations under and in accordance with this Agreement (including the exercise of licenses granted to Merck hereunder) on the condition that such Third Parties agree to be bound by confidentiality and non-use obligations that substantially are no less stringent than those confidentiality and non-use provisions contained in this Agreement; provided, however, that the term of confidentiality for such Third Parties shall be no less than five (5) years; or

is deemed necessary by NGM to be disclosed to employees, agent(s) and consultant(s), and/or other Third Parties for any and all purposes NGM and its Affiliates deem necessary or advisable for NGM to conduct the Collaboration, or to exercise and perform its rights and obligations under and in accordance with this Agreement (including the exercise of licenses granted to NGM hereunder) or for NGM’s scientific advisory board to perform its ordinary roles and responsibilities on the condition that such Third Parties agree to be bound by confidentiality and non-use obligations that substantially are no less stringent than those confidentiality and non-use provisions contained in this Agreement; provided, however, that the term of confidentiality for such Third Parties shall be no less than five (5) years;

is deemed necessary by a Party to be [*] provided, however, that the term of confidentiality for such investor, acquiror, merger partner or other financial partner shall be no less than five (5) years; or

is deemed necessary by counsel to the receiving Party to be disclosed to such Party’s attorneys, independent accountants or financial advisors for the sole purpose of enabling such attorneys, independent accountants or financial advisors to provide advice to the receiving Party, on the condition that such attorneys, independent accountants and financial advisors agree to be bound by the confidentiality and non-use obligations contained in this Agreement; provided, however, that the term of confidentiality for such attorneys, independent accountants and financial advisors shall be no less than seven (7) years.

Without limiting the provisions of Section 10.1, NGM agrees to keep all NP201 Know-How and NGM Know-How and Collaboration Inventions relating solely or primarily to a Program Compound or Product confidential, subject to Section 10.1.2. Such obligation, however, shall not apply to any such NP201 Know-How, NGM Know-How or Collaboration Inventions: (a) to the extent and as of the time, if any, that the Program Compound or Product to which they solely or primarily relate becomes, or upon termination under Article 13, a Reversion Product; or (b) to the extent relating to any Non-Qualifying Compounds, Non-Qualifying Targets or Refused Candidates.

Publication. Neither Merck nor NGM may publish or present results of the Collaboration without the prior written consent of the other Party. Each such Party shall provide the non-publishing Party with a copy of the proposed manuscript or presentation that includes results of the Collaboration at least [*] days prior to submission for publication or presentation. If the proposed manuscript or presentation contains information of the non-publishing Party that is subject to the use and nondisclosure restrictions under this Article 10, the publishing Party agrees to remove such information from the proposed publication or disclosure. Further, if the non-publishing Party believes the publication or disclosure of such results would be unfairly damaging to its ongoing research, Development or commercialization with respect to Program Compounds, Products, Small Molecule Collaboration Compounds or Small Molecule Products (if Merck is the non-publishing Party) or any Refused Candidates, Non-Qualifying Compounds, Non-Qualifying Targets, Reversion Compounds or Reversion Products (if NGM is the non-publishing Party, as of such time as they become such) and the non-publishing Party has a reasonable basis for not publishing or presenting such results, then, upon request of the non-publishing Party, the results shall not be published or presented until the matter is resolved. If the matter cannot be resolved between the Parties by mutual agreement, it shall be resolved in accordance with Section 16.7.

Use of Names. No Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except as may be required by Law or otherwise expressly permitted in this Agreement; except that where a Party has consented to a specific use of its name, trademark, trade name or logo by the other Party, such other Party shall have the right again to use such name, trademark, trade name or logo for such same specific use, without the consent of the other Party.

Exceptions to Confidentiality Obligations. A receiving Party may disclose Information of the disclosing Party if the receiving Party obtains the disclosing Party’s prior written consent to disclose the identified information. Moreover, the receiving Party may disclose Information of the disclosing Party solely to the extent required to be disclosed by the receiving Party to comply with Applicable Law (including securities laws or regulations and the applicable rules of any public stock exchange) or to defend or prosecute litigation or comply with an order of a court or other government order; provided, however, that the receiving Party notifies the disclosing Party of such order insofar as possible and provides reasonable assistance in obtaining a protective order or confidential treatment preventing or limiting the disclosure and/or requiring that the Information so disclosed be used only for the purposes for which the Law required, or for which the order was issued. For the avoidance of doubt: (i) Merck may disclose NGM’s Information as reasonably necessary for making regulatory filings in connection with the Development or Commercialization of Products or Small Molecule Products hereunder; (ii) NGM may disclose Merck’s Information as reasonably necessary for making regulatory filings in connection with: (a) the Development or Commercialization of any Reversion Compound or Reversion Product, or any NP201 Compound to the extent responsibility for such filing is allocated to NGM under the NP201 Research Plan; or (b) the development or commercialization of any Refused Candidate or Non-Qualifying Compound; and (iii) a Party controlling prosecution of any Patent Rights pursuant to this Agreement may disclose the other Party’s Information to Patent Offices in connection with such permitted prosecution.

Confidentiality of Agreement Terms. Each Party agrees not to, and to cause its Affiliates not to, disclose to any Third Party any terms of this Agreement without the prior written consent of the other Party hereto, except each Party and its Affiliates may disclose the terms of this Agreement: (a) to advisors (including financial advisors, attorneys and accountants), actual or potential acquirors or bona fide potential investors, and others on a need to know basis, in each case under appropriate confidentiality provisions substantially equivalent to those in this Agreement; or (b) to the extent necessary to comply with Applicable Laws and court orders (including securities laws or regulations and the applicable rules of any public stock exchange).

Publicity.

Initial Press Releases. The Parties acknowledge an intent to agree on the contents of a press release regarding this Agreement (including the existence and certain terms hereof) that can be issued by the Parties promptly after the Execution Date. For clarity, neither Party shall issue any such press release regarding this Agreement unless the form of such release has been mutually agreed upon by the Parties.

Further Publicity.

Investor Information. Each disclosing Party acknowledges that the other Party receiving the disclosing Party’s Information hereunder may, from time to time, be required by Law or rule of any stock exchange, such as Forms 8-K, 10-Q and 10-K, including as may be required by Law in connection with an initial public offering (IPO) (“Required Disclosure”), to publicly disclose the terms of this Agreement, or significant results or developments regarding any Products, to keep its investors reasonably informed of the achievement of milestones, significant events in the Development of Optioned Products and Commercialization activities and the like, and that such Required Disclosures may pertain to Information of the other Party that is not otherwise permitted to be disclosed under this Article 10. To the extent Merck discloses to NGM information related to events or circumstances involving the Development or Commercialization of any Product that NGM believes is insufficient to allow it to accurately determine the materiality of such information and whether is constitutes a Required Disclosure, Merck shall consider in good faith NGM’s reasonable questions with respect to such event so as to better enable it to assess such materiality.

Public Disclosure Review Procedure. With respect to any Required Disclosure, except for the initial press release described in Section 10.7.1, the receiving Party (the “Requesting Party”) shall provide the other Party (the “Reviewing Party”) with a draft of the Content (as defined in the next sentence) of the draft Required Disclosure for review, at least ten (10) Business Days in advance of the issuance of the filing of the Required Disclosure. The word “Content” in this Section 10.7.2(b) means any information relating to the activities contemplated by this Agreement, and does not include any other business information of the Requesting Party or information pertaining to the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 relating to “forward-looking statements.” The Reviewing Party may notify the Requesting Party of any reasonable objections or suggestions that the Reviewing Party may have regarding the Content in the Required Disclosure provided for review under this Section, and the Requesting Party shall reasonably consider any such objections or suggestions that are provided in a timely manner. The principles to be observed with respect to disclosures of information in a Required Disclosure shall include accuracy, disclosure of factual, rather than speculative information, compliance with Applicable Law and regulatory guidance documents, reasonable sensitivity to potential negative reactions of a Regulatory Authority, reasonable sensitivity to commercial information of value to competitors and the need to keep investors informed regarding the Requesting Party’s business. The Requesting Party shall use commercially reasonable efforts to adopt the reasonable requests of the Reviewing Party with respect to its Information and the Requesting Party shall remove such Information from the Required Disclosure if such Information is not required to be disclosed by Law. Notwithstanding the foregoing, NGM shall have the right to disclose in a press release the occurrence of the following research and development events arising from the Research Program and the NP201 Program: (1) achievement of any milestone event set forth in Section 9.5.1; (2) Merck’s exercise of a Merck Option; and (3) NGM’s exercise of an NGM ANS Option; provided, however, that NGM provides to Merck the Content of any such press release in the manner provided above, and, in the case where such Content does not also constitute a Required Disclosure, Merck approves such Content with respect to the particulars included pertaining to the events in clauses (1), (2) or (3), as applicable.

For any action to terminate any Licensed Infringement, in the event that the Party electing to initiate or prosecute such action in accordance with Section 12.4.1 is unable to initiate or prosecute such action solely in its own name, the other Party will join such action voluntarily and will execute and cause its Affiliates and Related Parties to execute all documents necessary for such Party to initiate litigation to prosecute and maintain such action. In connection with any such action, the Parties will cooperate fully and will provide each other with any information or assistance that either may reasonably request, at the expense of the requesting Party. Each Party shall keep the other informed of developments in any such action or proceeding, including, to the extent permissible by Law, consultation on and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

Any recovery obtained by either or both Merck and NGM in connection with or as a result of any action to terminate any Licensed Infringement contemplated by this Section 12.4, whether by settlement or otherwise, shall be shared in order as follows:

the Party that initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action;

the other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; and

the amount of any recovery remaining shall be [*].

Subject to the foregoing provisions of this Section 12.4, as between the Parties, NGM shall have the sole right to take action with respect to any infringement of Patent Rights owned by NGM (including NP201 Patents, NGM Patents and Collaboration Patents that are not Collaboration Compound Patents), and the first right to take action with respect to Collaboration Patents that are jointly owned by the Parties and are not Collaboration Compound Patents and Merck shall have the sole right to take action with respect to any infringement of Patent Rights owned by Merck, in each case, that is not a Licensed Infringement.

NGM shall inform Merck of any certification regarding any NP201 Patent, NGM Patent or Collaboration Patent under which Merck is granted a license under Sections 3.1.1, 5.4, and 6.1.1 through 6.1.4, inclusive, that it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the US, in each case where the certification pertains to the potential sale of a Product or Small Molecule Product, and shall provide Merck with a copy of such certification within [*] of receipt. NGM’s and

Patent Term Restoration. The Parties shall cooperate with each other, including to provide necessary information and assistance as the other Party may reasonably request, in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country in the Territory where NP201 Patents, NGM Patents and/or Collaboration Compound Patents exist, to the extent they relate to Program Compounds, Products, Small Molecule Collaboration Compounds or Small Molecule Products, as the case may be. In the event that elections with respect to obtaining such patent term restoration or supplemental protection certificates or their equivalents in any country in the Territory are to be made, Merck shall have the right to make the election with respect to NP201 Patents, NGM Patents and/or Collaboration Compound Patents that solely relate to Program Compounds, Products, Small Molecule Collaboration Compounds or Small Molecule Products. Subject to Merck’s rights in the previous sentence, each Party shall have the right to make the election with respect to other Patent Rights owned by such Party. In each case the other Party agrees to abide by such election.
