Each Party shall, itself or through its Affiliates, licensees or Sublicensees, use Commercially Reasonable Efforts to Commercialize the Collaboration Products in the Licensed Territory in accordance with the then-applicable Commercialization Plan and Budget and in accordance with the applicable Regulatory Approvals. For clarity, neither Party shall have any obligations to use Commercially Reasonable Efforts to Commercialize Collaboration Products in Canada, unless and until the Parties mutually agree in writing to Develop and Commercialize Collaboration Products in Canada pursuant to Section 5.1(b). Each Party shall use Commercially Reasonable Efforts to perform any and all of its Commercialization activities with respect to each Collaboration Product that are assigned to it under the applicable Commercialization Plan and Budget, in good scientific manner and in compliance with all applicable Laws and Licensee’s and its Affiliates’ internal policies and procedures applicable to such Commercialization activities (of which Licensee shall advise Seres in writing), provided that Seres shall not be required to comply with such internal policies and procedures of Licensee if doing so would be reasonably expected to result in a failure to comply with applicable Law or ethics rules to which Seres is bound to comply. In allocating the responsibilities among the Parties in relation to the Commercialization of Collaboration Products, the Parties shall endeavor to leverage the use of the existing infrastructure and systems of the Parties in order to minimize the costs associated therewith.

V.5Promotion in Licensed Territory.

(a)Each Commercialization Plan and Budget shall include the activities to be undertaken by Licensee and, if Seres elects to provide Details in accordance with Section 5.5(b), by Seres, with respect to promoting Collaboration Products in the United States and, if the Parties mutually agree in writing to Develop and Commercialize Collaboration Products in Canada, Canada, including the following matters, in each case, as applicable and agreed by the JCC and, in the case of the initial Commercialization Plan and Budget, consistent with Exhibit E hereto:

(i)the strategy and objectives of the Parties with respect to [***] the Collaboration Products for the Licensed Territory, including a [***];

(ii)[***], including the [***] to perform [***] for Collaboration Products, in the Licensed Territory in the Field;

(iii)designation of the [***];

(iv)[***] for such [***] during each [***] covered by the applicable [***];

(v)the conduct of [***] in the Licensed Territory, including the conduct of an [***];

(vi)the development of and updates to an [***] for the Licensed Territory;

(vii)[***] to be acquired and the acquisition of [***] for the Licensed Territory;

(viii)[***] strategies for the [***] with [***] and other applicable [***];

(ix)[***];

(x)other Market Access strategy and plans; and

38

(xi)[***] for the Collaboration Products.

For clarity, the activities in Section 5.5(a)(i)-(xi) for a Collaboration Product shall be included in the Commercialization Plan and Budget for such Collaboration Product to the extent agreed by the JCC and, in the case of the initial Commercialization Plan and Budget, consistent with Exhibit E.

(b)The Parties acknowledge and agree that, as of the Effective Date, the Parties intend that Licensee shall be responsible for performing all promotion activities and providing all Details for Collaboration Products in the Licensed Territory. At any time [***], Seres shall have the right to elect to provide up to [***] of all Details focused on [***]. If Seres elects to provide Details in accordance with the immediately preceding sentence, then the Commercialization Plan and Budget for such Collaboration Product shall be amended to include Seres’ provision of Details for Collaboration Products in such country. If Seres makes the election to provide Details in accordance with the foregoing, but desires to provide more than [***] of all Details in [***] for a Collaboration Product, then the specific percentage of Details to be provided by Seres, if it makes such request shall be determined by the JCC, but for clarity, in no event shall the percentage Seres is entitled to provide be less than [***]. Licensee and, if Seres elects to provide Details, Seres, shall be responsible for performing Details allocated to such Party in accordance with the Commercialization Plan and Budget for a Collaboration Product. The Parties acknowledge that, at any given time, each Party may not necessarily have an equal role in promotion activities under this Agreement (for example, each Party may not provide an equal number of Sales Representatives who will Detail Collaboration Products in a country in the Licensed Territory). The Parties agree that the allocation of responsibility for calling on members of the Target Audience by the personnel performing Detailing activities shall take into account the existing resources of Licensee and shall seek to leverage those resources to the maximum extent practicable while still maintaining Seres’ right to provide Details in accordance with this Section 5.5(b), if it makes the election to do so. During the first [***] following the First Commercial Sale of each Collaboration Product in the Licensed Territory, the Commercialization Plan and Budget for such Collaboration Product shall specify that no less than [***] of all Details for such Collaboration Product shall be either Exclusive Details or Primary Position Details.

(c)Licensee and, if Seres elects to provide Details in accordance with Section 5.5(b), Seres, shall perform its promotion obligations under each Commercialization Plan and Budget through Sales Representatives and other personnel under the direct and exclusive authority, supervision and control of such Party. A Party’s Sales Representatives and other personnel performing activities under the Commercialization Plan and Budget shall (i) not be debarred by a relevant Regulatory Authority, (ii) pass all relevant background checks required by such Party’s policies and procedures, and (iii) possess and maintain any required licenses, permissions or certifications required to Detail Collaboration Products to the Target Audience that he or she is expected to Detail, or perform other activities under the Commercialization Plan and Budget that such personnel is expected to perform. Each Party shall be solely responsible for any compensation that is payable to its Sales Representatives promoting Collaboration Products hereunder and its other personnel performing activities under the Commercialization Plan and Budget. Each Party agrees to include the Collaboration Products in its incentive compensation programs for its Sales Representatives in a manner reflecting the relative Detail position (e.g. Exclusive Details would receive the highest incentive compensation, Primary Position Details would receive the next

39

highest incentive compensation, and Secondary Position Details would receive lower incentive compensation). Each Party will hire and maintain a sufficient number of Sales Representatives and other personnel with appropriate expertise to permit such Party to perform fully the activities allocated to it for the Licensed Territory under this Section 5.5 and each applicable Commercialization Plan and Budget, in accordance with the job descriptions and time periods for hiring Sales Representatives and other personnel as set forth in the applicable Commercialization Plan and Budget. Compliance with such criteria will be monitored by the JCC pursuant to Section 3.2(c)(iv), including a determination of whether a Party has performed the required number of Details set forth in the applicable Commercialization Plan and Budget in each Calendar Quarter (the “Target Level”). If either Party fails at any time to meet the Target Level set forth in a Commercialization Plan and Budget (the percent of the Target Level number of Details that a Party has failed to provide, a “Shortfall”), then such Party shall, [***]. If the defaulting Party disputes whether a Shortfall has occurred, it may submit such dispute to the JCC for resolution.

(d)If Licensee or, if Seres elects to provide Details in accordance with Section 5.5(b), Seres, desires to provide a greater number of Sales Representatives or other personnel to perform activities under a Commercialization Plan and Budget, or anticipates that the actual costs to perform activities set forth in a Commercialization Plan and Budget will exceed the applicable portion of the relevant Commercialization Plan and Budget, then such Party shall so notify the JCC. The JCC shall discuss in good faith the reason(s) for such increase or excess and, following such discussion, the JCC shall determine whether to recommend to the JSC for approval an amendment to such Commercialization Plan and Budget to incorporate such increase or excess. If such increase or excess is approved by the JSC, then such Commercialization Plan and Budget shall be updated to reflect such increase or excess, and the costs attributable to such additional Sales Representatives or personnel, or otherwise in excess of such budget shall be included in Commercialization Costs. If the JSC does not approve such increase, then the costs attributable to such additional Sales Representatives or personnel, or otherwise in excess of such budget, shall not be included in Commercialization Costs, and such Party shall be solely responsible for any such increased or excess costs. Anything to the contrary notwithstanding, any increase in the relative number of Details to be performed by each Party, or to either Party’s Sales Representatives’ Target Audience shall only be made pursuant to an amendment to the then-current Commercialization Plan and Budget, approved in accordance with this Agreement.

(e)Following the First Commercial Sale, Licensee and, if Seres elects to provide Details in accordance with Section 5.5(b), Seres, shall provide to the other Party on a [***] basis a report of the number of aggregate Details (including the positions of such Details) and other material Commercialization efforts carried out by its Sales Representatives and personnel in each Calendar Quarter in the Licensed Territory. Each such report will be delivered no later than [***]. In furtherance thereof, each Party shall require its Sales Representatives and other personnel conducting Commercialization activities in the Licensed Territory to provide information on an ongoing basis in accordance with such Party’s customer relationship management or other systems, including without limitation call activity and account profiling information.

(f)[***] of the FTE Costs and Out-of-Pocket Costs of conducting an Exclusive Detail shall be included in Commercialization Costs. [***] of the FTE Costs and Out-of-Pocket Costs of conducting a Primary Position Detail shall be included in Commercialization Costs. The FTE Costs and Out-of-Pocket Costs of conducting a Secondary Position Detail that are included

40

in Commercialization Costs for a given Collaboration Product shall be determined by the JCC and approved by the JSC, but shall not exceed [***] of such FTE Costs and Out-of-Pocket Costs . For sake of clarity, the foregoing shall apply to Details conducted by Licensee or Seres, except that, [***], (i) [***], and (ii) if, at the time [***], then [***] shall be included in Commercialization Costs. Notwithstanding anything to the contrary, with respect to any Details provided by a Party, Commercialization Costs and Allowable Expenses shall exclude any costs or expenses incurred by such Party or its Affiliates to establish or scale up such Party’s or its Affiliates’ infrastructure or capabilities to provide such Details if, at the time such establishment or scale-up costs and expenses are incurred, the other Party has the infrastructure and capabilities necessary to provide such Details.

(g)Except as permitted hereby below, Licensee may not use any contract sales organizations to promote a Collaboration Product during the first [***] following the First Commercial Sale of such Collaboration Product. Thereafter, Licensee may use any contract sales organizations approved by the JCC to promote such Collaboration Product after consultation with the JCC. If Seres elects to provide Details in accordance with Section 5.5(b), except as otherwise permitted below, Seres may not use any contract sales organizations to promote a Collaboration Product during the first [***] following the First Commercial Sale of such Collaboration Product. Thereafter, Seres may use any contract sales organizations approved by the JCC to promote such Collaboration Product after consultation with the JCC. Notwithstanding anything herein to the contrary, either Party shall have the right to use personnel from contract sales organizations on a temporary basis (without the approval of the JCC) in connection with the promotion of Collaboration Products as part of its process of identifying and recruiting personnel.

Except with respect to the Product Trademarks, Licensee shall own all right, title and interest in and to all such manuals and materials and intellectual property rights therein. Licensee shall provide core promotional materials and manuals, as determined by the JCC, to Seres reasonably in advance of finalization thereof by Licensee, its Affiliates and Sublicensees, so that Seres has a reasonable period of time to review and provide comments thereon for consideration. Licensee shall consider in good faith any reasonable comments thereon provided by Seres. Licensee shall be responsible for any submissions to the applicable Regulatory Authorities of marketing, advertising or promotional materials that may be required under applicable Law and communications with such Regulatory Authorities in connection therewith. Seres shall provide to Licensee such assistance as Licensee may reasonably request in connection with such submissions and communications.

(b)All materials and other information used in connection with Commercialization activities in the Licensed Territory, including Collaboration Product labeling, package inserts and informational materials distributed for use in promoting Collaboration Products, oral presentations, direct-to-consumer advertising, patient information materials and patient benefit programs, that identify a Party in connection with a Collaboration Product, shall

(c)Each Party shall, and shall cause its Sales Representatives and other personnel performing Commercialization activities for Collaboration Products to, (i) use and distribute only the materials prepared in accordance with Section 5.6(a); and (ii) not modify, alter, amend, adjust or mask any portion of such materials in any way. Each Party will promptly notify the other Party and take all necessary corrective action in the event such Party learns that any such modification, alteration, amendment, adjustment or masking, or any such use or distribution of unapproved marketing materials for Collaboration Products has taken place by it or its Sales Representatives.

V.8Pricing. The JSC shall set the pricing, discounting and rebating strategy for each Collaboration Product in the Licensed Territory, including wholesale acquisition cost, list price, targeted net pricing, sales-weighted average discounts and rebates. The JCC will oversee the implementation of such decisions regarding costs, pricing, discounts and rebates and determine the optimal distribution flow of the Collaboration Products in the Licensed Territory, including which wholesalers, distributors and specialty pharmacies are eligible to buy and handle the Collaboration Products in the Licensed Territory. Licensee shall enter into contracts for the Collaboration Products with wholesalers, distributors, group purchasing organizations, specialty pharmacies, managed care organizations, pharmacy benefit managers, Centers for Medicare and Medicaid Services, U.S. Department of Veterans Affairs, U.S. Department of Defense, integrated delivery networks, accountable care organizations, and other applicable healthcare organizations.

45

“Deficit Party” for such Calendar Quarter and the Party having the higher Party Net Amount for the applicable Calendar Quarter being the “Surplus Party” for such Calendar Quarter; and

(B)the absolute value of the difference between the two Party Net Amounts for such Calendar Quarter shall be determined, with such amount, in dollars, being referred to as the “True-Up Delta” and the “True-Up Amount” for a particular Calendar Quarter being the amount equal to [***] of the True-Up Delta, subject to adjustment and payment in accordance with clause (v), below;

provided that, for the avoidance of doubt, consistent with Section 1.155, (A) income and withholding taxes imposed on either of the Parties or their Affiliates, (B) any payments made by Licensee to Seres pursuant to Section 7.1 or 7.2 and (C) indemnification payments by a Party to the other Party or to an Indemnitee hereunder or under the Supply Agreement, will not be included in the calculation of either Party’s Party Allowable Expenses or Receipts for any Calendar Quarter.

(iii)Within [***] following the reconciliation set forth in Section 7.4(b)(ii), the Royalty Payment Amount and True-Up Amount for each Calendar Quarter shall be adjusted, and a corresponding payment made, as follows:

(B)If Licensee owes a Royalty Payment Amount for such Calendar Quarter and is the Deficit Party for such Calendar Quarter, then (1) if the Royalty Payment Amount is greater than the True-Up Amount, Licensee shall pay to Seres an amount equal to such Royalty Payment Amount reduced by the True-Up Amount for such Calendar Quarter or (2) if such True-Up Amount exceeds such Royalty Payment Amount, Seres shall pay an amount equal to such excess to Licensee; and

(C)If no Royalty Payment Amount is owing for such Calendar Quarter, the Surplus Party shall pay an amount equal to the True-Up Amount for such Calendar Quarter to the Deficit Party.

(iv)Notwithstanding the foregoing, the Parties agree and acknowledge that certain elements of the Royalty Base Amount, Party Allowable Expenses and Receipts may be based on estimates during a Calendar Year (and as such, the foregoing amounts calculated on a quarterly basis are estimated amounts), and, as soon as reasonably practicable following the end of such Calendar Year, the Parties shall recalculate the Party Net Amounts as set forth in the foregoing provisions of

46

this Section 7.4(b) in order to take into account any changes to the estimates used to calculate the quarterly amounts. Thereafter, either Seres will make a payment to Licensee, or Licensee will make a payment to Seres, if and as necessary to ensure that each Party receives the amount to which it was entitled or pays the amount that it was required to pay, in each case, pursuant to Sections 7.4(a) and 7.4(b)(iii), as applicable, for such Calendar Year.

The negotiating Party shall keep the other Party updated with respect to its progress in negotiating and entering into such license and consider in good faith any comments of the other Party in connection therewith. For the avoidance of doubt, if such Third Party license agreement is entered into, then all Third Party payments due to such Third Party in the Licensed Territory [***] shall, if triggered by Commercialization of a Collaboration Product in the Licensed Territory, be included in the [***] for the Collaboration Product; provided that the [***] shall not exceed [***] (the “Third Party License Payments Threshold”).

73

SECTIONS 16.1, 16.2 AND 16.3, IN NO EVENT SHALL EITHER PARTY OR ANY OF ITS RESPECTIVE AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS AND EMPLOYEES BE LIABLE UNDER THIS AGREEMENT TO THE OTHER PARTY FOR SPECIAL, EXEMPLARY, INDIRECT, PUNITIVE, DAMAGES BASED UPON A MULTIPLE OF EARNINGS, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS, LOSS OF USE, DAMAGE TO GOODWILL, OR LOSS OF BUSINESS) SUFFERED BY THE OTHER PARTY UNDER THIS AGREEMENT, OF ANY KIND WHATEVER AND HOWEVER CAUSED, AND WHETHER BASED ON AN ACTION OR CLAIM IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT LIABILITY), BREACH OF STATUTORY DUTY OR OTHERWISE, AND EVEN IF FORESEEABLE OR SUFFERED IN CIRCUMSTANCES WHERE A PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES.

SERES THERAPEUTICS, NESTLÉ HEALTH SCIENCE ANNOUNCE SER-109 CO-COMMERCIALIZATION LICENSE AGREEMENT

Companies Agree to Jointly Commercialize SER-109 Investigational Microbiome Therapeutic to Treat Recurrent C. difficile Infection, Leading the Way for Entirely New Treatment Modality

Deal calls for more than $500 million in upfront and contingent milestone payments

Seres Therapeutics to conduct a conference call at 8:30 a.m. ET

CAMBRIDGE, Mass. and LAUSANNE, Switzerland -- July 1, 2021 -- Seres Therapeutics, Inc. (Nasdaq: MCRB), a leading microbiome therapeutics company, announced today that it has entered into an agreement with Nestlé Health Science to jointly commercialize SER-109, Seres’ investigational oral microbiome therapeutic for recurrent Clostridioides difficile infection (CDI), in the United States (U.S.) and Canada. If approved, SER-109 would become the first-ever FDA-approved microbiome therapeutic.

Under the terms of the agreement, Nestlé Health Science will utilize its global pharmaceutical business Aimmune Therapeutics and will assume the role of lead commercialization party. Seres will receive license payments of $175 million up front, and an additional $125 million upon FDA approval of SER-109. The agreement also includes sales target milestones which, if achieved, could total up to $225 million. Seres will be responsible for development and pre-commercialization costs in the U.S. Upon commercialization, Seres will be entitled to an amount equal to 50% of the commercial profits.

The agreement to co-commercialize SER-109 in the U.S. and Canada represents the expansion of an existing strategic collaboration between the companies. Nestlé Health Science already has commercial rights to Seres’ investigational treatments for CDI and inflammatory bowel disease outside of the U.S. and Canada, and with this expansion, Nestlé Health Science becomes Seres’ global collaborator in SER-109.

A leading cause of hospital-acquired infections in the U.S., CDI is associated with debilitating diarrhea and claims the lives of more than 20,000 Americans each year. SER-109 is comprised of purified Firmicutes spores, based on their modulatory role in the life cycle of C. difficile and disease pathogenesis. The bacterial consortium in SER-109 rapidly repopulates the microbiome in the gut to produce compositional and functional changes that are critical to a sustained clinical response.

“Nestlé Health Science has been a terrific collaborator in our quest to develop a new treatment option for patients suffering from recurrent C. difficile infection, and their support over the past few years has been critical in advancing SER-109 to address this unmet need,” Seres Therapeutics CEO, Xxxx Xxxxx, said. "We conducted a competitive process to select a collaborator for SER-109. As we prepare for potential approval and commercialization, we are

87

eager to embark side-by-side on our next phase with a company that believes as fervently as we do in the potential of this transformative approach to reduce the recurrence of CDI.”

“We are excited to expand our existing collaboration with Seres Therapeutics at this pivotal time, given the promise SER-109 holds for patients trapped in the debilitating cycle of recurrent C. difficile infection,” CEO of Nestlé Health Science, Xxxx Xxxxx, added. “Nestlé Health Science is focused on the fast-developing areas of gut health, food allergies and metabolic health within our global pharmaceutical business, Aimmune Therapeutics. We look forward to leveraging Aimmune’s existing, fully integrated commercial infrastructure and capability to launch this important medicine, once approved.”

Nestlé Health Science continues to make significant investments in innovation while leveraging leading-edge science. Its pharma arm, Aimmune Therapeutics, has a strong presence in the field of gastroenterology, allowing it to lead the commercialization of SER-109 while providing Seres the ability to retain a strategic role and actively participate in the launch.

SER-109 Clinical & Regulatory Milestones

In August 2020, Seres announced that SER-109 had met the primary endpoint from the pivotal Xxxxx 0 XXXXXXX XXX study, showing a highly statistically significant reduction in the rate of CDI recurrence compared to placebo at 8 weeks, with an absolute reduction of 27% and a relative risk reduction of 68%. In a separate measure, approximately 88% of patients achieved sustained clinical response at week 8.

The Company expects that the ECOSPOR III efficacy results should support a BLA filing as a single pivotal trial once the SER-109 safety database includes at least 300 treated subjects monitored for 24 weeks, based on feedback from the FDA.

A SER-109 open-label study is ongoing and continues to contribute to the SER-109 safety database. Completion of target enrollment is anticipated in Q3 of 2021.

Responsibility for oversight of activities to support SER-109 will be governed by a Joint Steering Committee composed of an equal number of members from each company. Seres is responsible for the manufacturing and supply of SER-109 for all geographies contemplated in the collaboration in addition to ex-North America. Seres will lead medical affairs activities pre-launch and Aimmune Therapeutics will lead commercialization and medical affairs activities post-launch.
