8.Indemnity

8.1Atreca’s Right to Indemnification. Subject to Section 8.3, the Gates MRI will (a) defend each of Atreca, its Affiliates, successors and assigns and their respective directors, officers, employees, and agents from and against any third party claim, action, suit, or proceeding (“Claim”) based on: (i) the Development, Manufacture, or Commercialization of Licensed Products by the Gates MRI or its Affiliates, agents, subcontractors, or sublicensees; (ii) the negligence or intentional misconduct of the Gates MRI or any of its agents or employees, or Affiliates, subcontractors or sublicensees, or (iii) any material breach by the Gates MRI or its Affiliates, agents, subcontractors or sublicensees of any term (including any material inaccuracy or other breach of any representation or warranty made by the Gates MRI) of this Agreement, except in each case ((i) through (iii)), to the extent that Atreca is obligated to indemnify the Gates MRI against such Claim pursuant to Section 8.2, and (b) pay any damages, costs, and expenses finally awarded against Atreca as a result of, and attributable to, such Claim.

8.2The Gates MRI’s Right to Indemnification. Subject to Section 8.3, Atreca will (a) defend each of the Gates MRI, its Affiliates, successors and assigns and their respective directors, trustees, officers, employees, and agents from and against any Claim based on: (i) the Development, Manufacture, or Commercialization of Licensed Products by Atreca or its Affiliates, agents, subcontractors, licensees or Atreca Sublicensees; (ii) the negligence or intentional misconduct of Atreca or any of its agents or employees or Affiliates, subcontractors, licensees or Atreca Sublicensees, or (iii) any material breach by Atreca or its Affiliates, agents, subcontractors, licensees or Atreca Sublicensees of any term (including any material inaccuracy or other breach of any representation or warranty made by Atreca) of this Agreement, except in each case ((i) through (iii)), to the extent that the Gates MRI is obligated to indemnify Atreca against such Claim pursuant to Section 8.1, and (b) pay any damages, costs, and expenses finally awarded against the Gates MRI as a result of, and attributable to, such Claim.

8.3Process for Indemnification. For purposes of Sections 8.1 and 8.2, the Party seeking indemnification will give prompt written notice to the indemnifying Party of any Claims that may give rise to any claim for which indemnification may be required under this Section 8, provided, however, that failure to give such notice will not relieve the indemnifying Party of its obligation to provide indemnification hereunder except if and to the extent that such failure materially and adversely affects the ability of the indemnifying Party to defend against or mitigate the applicable Claim. The indemnifying Party will be entitled to assume control of the defense of any such Claim at its own cost and expense, provided, however, that the other Party will have the right to be represented by its own counsel at its own cost in such matters. Neither the indemnifying Party nor the indemnified Party will settle or dispose of any Claim in any manner

Execution Version

that would adversely affect the rights or interests of the other Party (including the obligation to indemnify hereunder) without the prior written consent of the other Party, which will not be unreasonably withheld or delayed. Each Party will cooperate with the other Party and its counsel in the course of the defense of any such Claim, such cooperation to include using reasonable efforts to provide or make available documents, information and witnesses.

9.Intellectual Property

9.1Retention of Rights. Each Party will retain ownership of its Information and Intellectual Property Rights, including its Patents and any rights in its Shared Data and Regulatory Submissions, subject to the licenses and other rights set forth herein.

9.2Inventions. Ownership will follow inventorship for any and all Information, improvements and inventions developed, created, conceived or reduced to practice by or on behalf of a Party in the performance of its obligations or the exercise of its rights under this Agreement during the term of this Agreement, including all Intellectual Property Rights thereto (collectively “Inventions”), with inventorship to be determined in accordance with United States patent laws (regardless of where the applicable activities occurred). For the avoidance of doubt, Inventions developed, created, conceived or reduced to practice solely by or on behalf of Atreca or any of its Affiliates will be solely owned by Atreca or its Affiliates. Inventions developed, created, conceived or reduced to practice solely by or on behalf of the Gates MRI or any of its Affiliates will be solely owned by the Gates MRI or its Affiliates. Inventions invented jointly by or on behalf of Atreca or any of its Affiliates on the one hand, and the Gates MRI or any of its Affiliates, on the other hand, will be jointly owned by both Parties (“Joint Inventions”). If the Gates MRI has or acquires Control of any Patents on Inventions in countries outside of the Territory that are reasonably necessary or useful for the Development, Manufacture, or Commercialization of Licensed Products in the Licensed Field outside of the Territory (the “Additional Gates Patents”), the Gates MRI will promptly notify Atreca. The Gates MRI hereby grants Atreca [***]. Atreca may exercise its right to negotiate such license by notifying the Gates MRI in writing within [***] days from the date of such disclosure by the Gates MRI to Atreca (“Option Period”). If Atreca exercises its option during the Option Period, the Gates MRI and Atreca shall negotiate the terms of such license in good faith, on commercially reasonable terms, for a period of [***] days from the date such option is exercised (“Negotiation Period”). If Atreca and the Gates MRI fail to enter into such license agreement with respect to any specific Additional Gates Patent within the applicable Negotiation Period (including any extension thereof as the Parties may mutually agree), the Gates MRI shall have no further obligation to Atreca with respect to such Additional Gates Patent.

9.3Prosecution and Enforcement. Each Party will be responsible, at its own discretion and expense, for filing, maintaining, prosecuting, and defending its Intellectual Property Rights. Specifically, Atreca will be responsible for the filing, maintaining, prosecuting, and defending the Licensed Patents, provided that Atreca will provide the Gates MRI with a reasonable opportunity to comment upon any proposed Patent filings and prosecution strategies for the Licensed Patents in the Territory pertaining to the Licensed Products. Atreca will provide in a timely fashion (at least [***] weeks before submission) to the Gates MRI a draft version of all patent application filings and applicant responses to patent prosecution office actions, or other administrative proceedings that could substantively affect the scope of eventual patent rights, and consider any comments made by the Gates MRI in response thereof, in good faith. If Atreca decides at any time not to prosecute or maintain a Licensed Patent in any country in the Territory, Atreca will provide written notice of such decision to the Gates MRI, and the Gates MRI will have the right to assume the prosecution and maintenance of such Licensed Patent or take ownership of such Licensed Patent.

Execution Version

9.4Further Assurances. Each Party will take all such further actions, and execute such documents and instruments, as may be necessary to convey to give effect to the intent of the Parties as expressed herein and to perfect, clarify, confirm, record, evidence, enforce, and defend the rights granted by such Party to the other Party under this Agreement.

10.Term and Termination

10.1Term of Agreement. This Agreement will be effective as of the Effective Date and will continue until the last to expire of the Licensed Patents, or twenty (20) years from the Effective Date if no Licensed Patent issues, unless earlier terminated in accordance with the terms herein.

10.2Termination for Breach or Bankruptcy. If either Party materially breaches any of its obligations under this Agreement, the non-breaching Party, at its option, will have the right to terminate this Agreement by written notice to the other Party, if (a) such other Party does not cure such breach within [***] days after being notified of such breach by the non-breaching Party or (b) such breach cannot be cured, and the breaching Party does not [***] of such breach. In addition, either Party may immediately terminate this Agreement by giving written notice to the other Party upon the filing by or with respect to the other Party of a petition in bankruptcy or insolvency under any laws of any jurisdiction, the rendering of any adjudication that the other Party is bankrupt or insolvent, the filing or making of any statement or admission that the other Party is unable to pay its debts as they generally become due or that it is insolvent, or the making of any assignment for the benefit of creditors or similar process.

10.3Additional Termination Rights. The Gates MRI may discontinue its activities hereunder and terminate this Agreement without cause at any time upon [***] written notice to Atreca.

10.4Effect of Termination. Upon any termination or expiration of this Agreement, except as otherwise expressly set forth herein, (a) any and all rights and obligations of the Parties under this Agreement will terminate, except for any obligations and liability accrued prior to termination or expiration and (b) each Party will return or destroy, at the other Party’s option (communicated in writing, where email is sufficient), all Confidential Information of the other Party in its possession, except as set forth in Section 6.2. Upon termination of this Agreement by Atreca for the Gates MRI’s breach or bankruptcy in accordance with Section 10.2, or the Gates MRI’s termination of this Agreement in accordance with Section 10.3, the license granted by Atreca to the Gates MRI pursuant to Section 2 (and the corresponding covenant set forth in Section 2.4 and license granted by Atreca to the Gates MRI pursuant to Section 4.3(a)) will immediately terminate. Upon termination of this Agreement by the Gates MRI for Atreca’s breach or bankruptcy in accordance with Section 10.2, the license granted by the Gates MRI to Atreca pursuant to Section 4.3(b), and Atreca’s right to request a CMC Technology Transfer pursuant to Section 4.3(c) will immediately terminate.

10.5Survival. The provisions of the following Sections will survive the termination or expiration of this Agreement for any reason: Sections 1, 5 (for any amounts owed but unpaid as of the termination or expiration of this Agreement), 6, 8, 9.1, 9.2, 9.4, 10.4, 10.5, 11 and 13. In addition, Sections 2 and 4.3(a)-4.3(c) (including Atreca’s Commercial License and the right to request a CMC Technology Transfer, subject to Sections 5.2 through 5.6) will survive except as set forth in Section 10.4.

11.Limitation of Liability

EXCEPT FOR A PARTY’S INDEMNIFICATION OBLIGATIONS PURSUANT TO SECTION 8 OR LIABILITY ARISING FROM BREACH OF CONFIDENTIALITY OBLIGATIONS UNDER SECTION 6, IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, OR INDIRECT DAMAGES OF ANY KIND, OR ANY

Execution Version

LOST PROFITS OR LOSS OF BUSINESS, ARISING IN ANY WAY OUT OF THIS AGREEMENT, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY.

12.Insurance

Each Party, at its sole cost and expense, will maintain during the term of this Agreement adequate insurance, with reputable and financially secure insurance carriers, for its activities hereunder. Such insurance coverage, however, will not limit such Party’s liability under this Agreement.

13.General

13.1Notices. Unless otherwise specifically stated in this Agreement, all notices required hereunder will be in writing and will be sent by an internationally-recognized courier service (e.g., DHL, Federal Express), with all postage or delivery charges prepaid, subject to confirmation via internationally-recognized courier service, and will be addressed to the Parties at their addresses set forth on the first page of this Agreement or to such other addresses as may be furnished by written notice in the manner set forth herein.

13.2Relationship of the Parties. This Agreement will not be construed as creating an agency, partnership, joint venture, or any other form of legal association between the Parties other than as expressly set forth herein. No Party will have any right or authority to assume or create any obligation of any kind or to make any representation or warranty on behalf of the other Party, whether express or implied, or to bind the other Party in any respect whatsoever.

13.3Assignment. Neither Party may assign this Agreement or any of its rights or obligations under this Agreement without the prior written consent of the other Party, such consent not to be unreasonably withheld, and any purported assignment without such consent will be void. However, a Party may, in its sole discretion and without any obligation to obtain the consent of the other Party, assign this Agreement, in whole or in part, to an Affiliate of such Party (or, in the case of the Gates MRI, to an Affiliate of the Foundation organized for a charitable purpose or to a collaboration partner). The assigning Party will not be relieved of its obligations under this Agreement but will be jointly and severally liable with the assignee. Subject to the foregoing, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the Parties.

13.4Publicity. Within [***] after the Effective Date, Atreca shall have the right to issue a press release, a copy of which has been approved by the Gates MRI as of the Effective Date. Any other press releases or other public announcements regarding this Agreement must be approved in writing by each Party (where e-mail is sufficient) and the Party receiving such a request will have a reasonable amount of time to review and respond. Each Party may use the name and logo of the other Party for applicable regulatory filings and, only with the prior written approval of the other Party, for collaboration identification on its website and reuse or incorporation of approved press releases. Except for publication of the mutually agreed press release, neither Party will use the name or logo of the other Party or its Affiliates in any other public or promotional materials (including printed materials, email signatures, business cards, client lists, letterhead and the like) without the prior written consent of the other Party (where e-mail is sufficient).

13.5Compliance With Laws. Each Party will comply with all laws, regulations and governmental requirements applicable to the exercise of its rights and performance of its obligations under this Agreement, including all applicable anti-corruption laws.

Execution Version

any act or decision relating to this Agreement, including by assisting any person or entity to secure an improper advantage.

13.6Debarment. Each Party warrants that, in performing this Agreement, neither it nor any person or entity providing services to that Party in furtherance of this Agreement (including their respective officers, directors, partners, employees and agents) are or have been (a) debarred or suspended pursuant to 21 U.S.C. § 335a or under investigation by the FDA or another relevant regulatory authority for debarment, (b) disqualified or deemed ineligible pursuant to 21 U.S.C. Parts 312, 511, or 812, or otherwise, in whole or in part, restricted, disqualified, or subject to an assurance by the FDA, or (c) subject to pending or threatened action, suit, demand, claim, hearing, proceeding, notice, or investigation related to or that may reasonably result in an enforcement action.

13.7Political Activity and Advocacy. Atreca may not engage in activities that are related to this Agreement to: (a) influence the outcome of any election for public office, or (b) support lobbying or other attempts to influence legislation, unless such activities are consistent with the private foundation lobbying rules under U.S. tax law and generally described in the Foundation’s advocacy guidelines, currently available at https://docs.gatesfoundation.org/documents/advocacy-guidelines.pdf, which may be modified from time to time. In performing services or conducting any other activities under, or related to, this Agreement, Atreca will (i) work closely with the Gates MRI to ensure that any communications with government officials regarding potential legislation or legislative proposals, as well as public statements including “calls to action,” are consistent with the rules governing direct and grassroots lobbying activity, and (ii) comply with all lobbying, gift, and ethics requirements. These restrictions apply globally.

13.8Force Majeure. Neither Party will be liable to the other Party for any failure or delay in performance caused by an event that is beyond such Party’s reasonable control, including an act of God, act of the other Party, war, riot, civil commotion, terrorist act, malicious damage, epidemic, quarantine, fire, flood, storm, natural disaster, or compliance with any law or governmental order, rule, regulation or direction, whether or not it is later held to be invalid or inapplicable.

13.9Governing Law; Venue. This Agreement will be construed and enforced in accordance with the laws of the state of Delaware without regard to conflicts of laws provisions thereof. Any disputes arising hereunder will be resolved exclusively in Delaware state courts and United States federal courts located in Delaware.

13.10Remedies Cumulative. Unless expressly set forth herein to the contrary, a Party’s election of any remedies provided for in this Agreement will not be exclusive of any other remedies available hereunder or otherwise at law or in equity, and all such remedies will be deemed to be cumulative.

13.11No Waiver. No failure or delay by a Party in exercising any right, power, or remedy under this Agreement will operate as a waiver of any such right, power, or remedy. No waiver of any provision of this Agreement will be effective unless in writing and signed by the Party against whom such waiver is sought to be enforced.

13.12Amendments. No amendment to or modification of this Agreement will be binding on a Party unless such amendment or modification is agreed to in writing and signed by a duly authorized representative of such Party.

13.13Severability. In the event that any provision of this Agreement (or any portion thereof) is determined by a court of competent jurisdiction to be illegal, invalid or otherwise unenforceable, such provision (or part thereof) will be enforced to the extent possible, consistent with the stated intention of the Parties, or, if incapable of such enforcement, will be deemed to be deleted from this Agreement, while the

Execution Version

remainder of this Agreement will continue in full force and remain in effect according to its terms and conditions.

13.14No Third Party Beneficiaries. Except as otherwise expressly set forth herein, no provisions of this Agreement are intended or will be construed to confer upon or give to any person or entity other than the specific parties hereto any rights, remedies, or other benefits under or by reason of this Agreement.

13.15Rights in Bankruptcy. Each Party agrees, on behalf of itself and its Affiliates, that the other Party will retain and may fully exercise all rights and licenses granted by such Party to the other Party under this Agreement in any future bankruptcy or insolvency proceeding involving such Party or any of its Affiliates, whether as licensees of intellectual property under the U.S. Bankruptcy Code or similar laws of other countries, applicable non-bankruptcy law, or otherwise. Without limiting the foregoing, each Party acknowledges and agrees, on behalf of itself and its Affiliates, that (a) neither this Agreement nor any of the rights and licenses under this Agreement is vulnerable to rejection as an executory contract under Section 365 of the U.S. Bankruptcy Code or similar laws of other countries; (b) if a court of competent jurisdiction nonetheless allows the rejection of this Agreement under Section 365 of the U.S. Bankruptcy Code or similar laws of other countries, such rejection will not result in termination of any of the rights and licenses granted to the other Party under this Agreement; and (c) if a court of competent jurisdiction nonetheless allows the rejection of this Agreement and termination of any of the rights and licenses under this Agreement, such rights and licenses will be treated as licenses of “intellectual property” for purposes of Section 365(n) of the U.S. Bankruptcy Code or similar laws of other countries and, accordingly, the other Party and its sublicensees and contractors will retain and may fully exercise all rights and elections under the U.S. Bankruptcy Code or similar laws of other countries with respect to the rights and licenses under this Agreement. Neither Party nor any of its Affiliates may (and such Party, on behalf of itself and its Affiliates, hereby irrevocably waives any right to) object to or challenge any assertion of and reliance on the matters described in this Section 13.15 by the other Party, its Affiliates or its sublicensees or contractors.

13.16Construction. This Agreement will be deemed to have been drafted by both Parties and, in the event of a dispute, neither Party will be entitled to claim that any provision should be construed against the other Party by reason of the fact that it was drafted by the other Party. For purposes of this Agreement, (a) the terms “hereof,” “herein,” “hereunder,” and similar words refer to this Agreement as a whole and not to any particular provision of this Agreement and (b) the term “including” is not limited and means “including without limitation.” The section headings used in this Agreement are intended for reference and will not by themselves determine the construction or interpretation of this Agreement or any portion hereof.

13.17Entire Agreement. The terms set forth in the “Background” section on the first page of this Agreement, including all defined terms referenced therein, are incorporated into and made a part of this Agreement. This Agreement, including all Schedules hereto, constitutes the entire agreement and understanding of the Parties with respect to the subject matter hereof, and supersedes all prior and contemporaneous correspondence, negotiations, agreements and understandings among the Parties, both oral and written, regarding such subject matter. Notwithstanding the foregoing, nothing in this Agreement supersedes any terms of, or limits any rights of either Party or its Affiliates under, the Existing Agreements.

13.18Execution of Agreement; Counterparts. This Agreement and any amendment hereto may be executed in any number of counterparts, each of which when executed and delivered will be deemed to be an original and all of which counterparts taken together will constitute but one and the same instrument. The exchange of copies of this Agreement or amendments thereto and of executed signature pages by facsimile transmission or by email transmission in portable document format (PDF), or similar format, will constitute effective execution and delivery of such instruments as to the Parties and may be
