promptly notify Bayer of the acquisition by Atara or any of its Affiliates of any New Technology, including a description of the type of such New Technology, its potential benefits known to Atara with respect to the Exploitation of Licensed Products and [[***]]; and

within [[***]] after such notification, offer Bayer a license [[***]], such license to form part of the licenses granted under this Agreement, subject to any limitations resulting from the terms of the upstream license as specifically disclosed by Atara to Bayer.

Sublicensing Party’s Responsibility. For the avoidance of doubt, any sublicense granted hereunder shall (i) be subject to the terms of this Agreement (including, where applicable, the consent of the applicable upstream licensor) and (ii) not relieve the sublicensing Party from any of its obligations under this Agreement. In addition, any act or omission by a Sublicensee of a Party in connection with this Agreement that, if committed by such Party would be a breach of this Agreement, shall constitute a breach of this Agreement by such Party, provided that Atara shall not have the right to terminate this Agreement pursuant to Section 18.2.2 for an uncured material breach by Sublicensee if (i) such breach was not made at the direction or with the approval of Bayer or a Bayer Affiliate and (ii) upon Atara’s request, Bayer causes such Sublicensee to cure such breach within [[***]] days following such notice or, if the Sublicensee fails to cure the breach within such period, terminates the sublicense after the end of the applicable cure period within [[***]] Business Days from Bayer’s receipt of a request from Atara to terminate the sublicense. Notwithstanding the foregoing, [[***]].

Notice to Atara.

Bayer shall provide written notice thereof to Atara within [[***]] Business Days after entering into any sublicense permitted under Section 2.1.1 (other than to an Affiliate of Bayer, provided that should any such Affiliate of Bayer cease to be an Affiliate of Bayer at any time during the Term, Bayer shall within [[***]] Business Days provide written notice to Atara of the applicable sublicense to such former Bayer Affiliate). Bayer will provide to Atara a complete copy of the relevant sublicense agreement within [[***]] days following its execution; provided, however, that the terms of any such sublicense agreement may be redacted to the extent they are not necessary to assess whether Bayer is in compliance with this Agreement. In addition, and notwithstanding the above, if the sublicense agreement includes any sublicense grant from Bayer to a Third Party under the NIH Upstream License, once such sublicense agreement is substantially complete, Bayer shall promptly deliver a copy of such draft to Atara (and Atara shall promptly deliver such copy to NIH) in order to permit NIH to exercise the rights set forth in Section 4 of the NIH Upstream License, it being understood that NIH shall have at least [[***]] Business Days from delivery of such copy by Atara to review and provide comments on such draft, and Atara will promptly provide such comments, if any, to Bayer. Without limiting the foregoing, any such sublicense agreement will be subject to NIH’s consent pursuant to the NIH Upstream License, provided that, should Atara fail to provide a response to Bayer within [[***]] Business Days from delivery to Atara of the substantially complete draft referenced above, Bayer may execute and enter into such sublicense agreement.

Without limiting the foregoing,

any sublicense grant from Bayer to a Third Party that at the time of such grant is engaged in the Development and/or Commercialization, whether on its own or together with its affiliates or Third Parties, of any [[***]] requires Atara’s prior written approval, which approval Atara may not unreasonably withhold, condition or delay; and

any sublicense grant from Bayer to a Third Party under the NIH Upstream License requires Atara’s prior written approval, which approval Atara may only withhold on the grounds of [[***]]; and

any sublicense grant from Bayer to a Third Party under the BioVec Upstream License must be in connection with a license under further Licensed Technology and requires Atara’s prior written approval, which approval Atara may only withhold on the grounds of [[***]].

Option for Sublicense under MOFFITT Upstream License. For [[***]] (the “MOFFITT Option Period”), provided that Atara has no obligation to amend or attempt to amend the MOFFITT Upstream License to extend the term thereof, Atara hereby grants to Bayer an option - which option Bayer may only exercise upon the occurrence of [[***]] - to negotiate with Atara a non-exclusive sublicense under the MOFFITT Upstream License [[***]]. Bayer may exercise such option right by written option exercise notice during the MOFFITT Option Period or the term of this Agreement, whichever ends sooner. Upon Atara’s receipt of any such option exercise notice, Atara shall within due course, but in no event later than [[***]] after receipt of the notice, offer Bayer to include the relevant MOFFITT Upstream License in the definition of “Licensed Technology” under this Agreement [[***]], which offer will include, with respect to such MOFFITT sublicense, any deviations from this Agreement that are [[***]] required to ensure consistency with the terms and conditions of the relevant MOFFITT Upstream Licenses, and conditional upon MOFFITT’s approval, in each case if and to the extent required for Atara to comply with its contractual obligations under the MOFFITT Upstream License. Atara will use [[***]] efforts to obtain MOFFITT’s approval of the sublicense grant to Bayer and, upon Bayer’s reasonable request, to negotiate with MOFFITT any further amendments which may be required to grant Bayer the right to use the relevant MOFFITT Upstream License with the same scope as the rights granted by Atara to Bayer under the Licensed Technology pursuant to Section 2.1.

Option for Other CAR-Ts. Bayer will receive the following preferential treatment in the event that Atara or any of its Affiliates has determined to out-license or otherwise grant any Development or Commercialization rights to Third Parties (for clarity, except for ancillary rights granted to contractors, consultants, or other Third Parties engaged by Atara or any of its Affiliates to perform services for or on behalf of Atara or any of its Affiliates) under any Patent Rights or Know How covering any Other CAR-T, in each case to the extent legally possible without breaching any Laws (including on data privacy) or obligations (including contractual obligations) towards Atara’s licensors with respect to such Other CAR-T or any other Third Parties who possess any rights, interest or title in any such Other CAR-T, provided that Atara shall not agree on contractual restrictions that limit Atara’s ability to grant a license specifically to Bayer whilst not limiting Atara’s ability to grant a license to Third Parties generally (for clarity, notwithstanding Atara’s right to grant to its contractors, consultants or other Third Parties performing services for Atara or any of its Affiliates or otherwise acting on Atara’s or its Affiliates’ behalf all rights required for performance of such services):

Subject to Section 2.5.2.9, during the [[***]] period beginning on the Effective Date, Atara will promptly inform Bayer in writing about the Other CAR-T and the availability of a license thereunder prior to [[***]] and will, upon written request of Bayer to be submitted within [[***]] Business Days upon receipt of Atara’s notification, negotiate in good faith a respective agreement with Bayer.  Notwithstanding the foregoing or anything to the contrary contained in Section 2.5.2, Atara shall, at all times, be free to enter into negotiations with any Third Parties for a license to any such Other CAR-T following notification of Bayer

pursuant to this Section 2.5.2.1 and, for clarity, Atara may continue to negotiate with any such Third Parties while separately and concurrently negotiating with Bayer for a license to any such Other CAR-T (including the same Other CAR-T), in each case subject to Bayer’s other rights under Section 2.5.2.

Subject to Section 2.5.2.9, during the [[***]] period beginning on the Effective Date, Atara hereby additionally grants Bayer a right of [[***]] prior to any grant of rights under such Other CAR-T programs to Third Parties, as described in detail in Sections 2.5.2.3 - 2.5.2.8 below.

If Atara reaches final agreement on a term sheet or, in the absence of any final agreement on a term sheet before a definitive agreement is drafted, on the key business terms with a Third Party with respect to the transfer of, or grant of license or rights under, any Other CAR-T (whether by assignment, license or otherwise) (a “Preliminary Third Party Offer”), Atara shall notify Bayer in writing within [[***]] days of reaching such agreement, which notice shall include [[***]] - for such Preliminary Third Party Offer (a “Preliminary Third Party Offer Notice”). Such notice shall be subject to any applicable confidentiality obligations to such Third Party; provided that Atara shall [[***]]. Bayer shall have [[***]] Business Days after Atara has delivered to Bayer such Preliminary Third Party Offer Notice to deliver a written response to Atara, which response shall include [[***]].

If Atara determines in good faith that such Preliminary Bayer Offer is [[***]], taking into consideration all material terms thereof but not any terms undisclosed to Bayer, Atara shall so notify Bayer in writing, and (i) Atara will promptly enable Bayer to perform a customary due diligence on the applicable Other CAR- and (ii) within [[***]] days from Bayer’s receipt of such notice from Atara  – such period to be extended in good faith upon written request of Bayer if both Parties are still in active negotiations – the Parties shall use good faith efforts to [[***]].

Prior to entering into a definitive agreement with any Third Party with respect to the transfer of, or grant of license or rights under, the Other CAR-T (whether by assignment, license or otherwise, Atara shall review whether the envisaged final agreement deviates in any respect from [[***]]. In case of any such deviations, Atara shall provide Bayer with a written summary of such differences, including its assessment whether these deviations are material in any of the following manners:

at least [[***]] percent [[***]] deviation of [[***]] to be paid to Atara or any Affiliate of Atara up to (including) first commercial sale of a licensed product;

at least [[***]] percent [[***]] change of [[***]] to be paid to Atara or any Affiliate of Atara;

any material change of [[***]], licensed field or licensed territory; or

any material change of [[***]], supply and commercialization activities;

Bayer shall have [[***]] Business Days following Atara’s delivery to Bayer of a Final Third Party Offer Notice [[***]] to deliver a written counter-offer to Atara (a “Final Bayer Offer”), and Atara shall within [***]] Business Days upon receipt of such Final Bayer Offer determine in good faith - and provide written notice thereof to Bayer - whether the terms of such Final Bayer Offer are [[***]], taking into consideration all material terms thereof, but not any terms undisclosed to Bayer. If Atara, in its reasonable discretion based solely on a comparison of the Final Third Party Offer Notice and the Final Bayer Offer, determines that the Final Bayer Offer is [[***]], Atara shall so notify Bayer in writing, and (i) Atara will promptly enable Bayer to perform a customary due diligence on the applicable Other CAR-T and (ii) within [[***]] days from Bayer’s receipt of such notice from Atara  – such period to be extended in good faith upon written request of Bayer if both Parties are still in active negotiations – the Parties shall use good faith efforts to enter into a license agreement with respect to such Other CAR-T on the terms of the Final Bayer Offer. If Atara, in its reasonable discretion based on the principles specified above, determines that the Final Bayer Offer is [[***]], Atara shall so notify Bayer in writing.

If Atara disagrees with Bayer’s Objection Notice or if Bayer objects within [[***]] days after receipt of notice of Atara’s determination that a Preliminary Bayer Offer or Final Bayer Offer is [[***]], the objecting Party shall notify the other Party of the dispute and the issue shall be referred to each Party’s Executive Sponsor who shall meet within [[***]] Business Days (in person, by means of telephone conference, videoconference or other means of communications) and attempt in good faith to resolve such issue within such [[***]] Business Days period (subject only to, in the case of Atara, approval of its board of directors or, in the case of Bayer, approval of the applicable management board, if required). Notwithstanding the foregoing, if [[***]].

If, [[***]] Atara shall thereafter be free to enter into an agreement with such Third Party related to such Other CAR-T based on the Final Third Party Offer. For clarity, Bayer’s option with respect to any particular Other CAR-T shall [[***]].

Notwithstanding anything to the contrary contained in this Agreement, the options and preferential treatment granted to Bayer and Atara’s obligations under Section 2.5.2 will, at Atara’s option, terminate in the event that Atara enters into a transaction or series of transactions with a Third Party acquiror that constitutes a Change of Control of Atara, provided that such Third Party is an entity that, immediately prior to the entering into such Change of Control transaction(s), (a) is active in the field of [[***]] and (b) has either (i) a market capitalization of at least [[***]], or (ii) reported revenue of more than [[***]] in the [[***]] month period preceding such Change of Control transaction(s). Atara may exercise such option

by written notice to Bayer within [[***]] following any such Change of Control of Atara. For clarity, the foregoing sentence does not apply in the reverse scenario where Atara acquires a Third Party subject to the Change of Control definition in this Agreement. If Atara’s obligations under Sections 2.5.2.2-2.5.2.8 terminate pursuant to this Section 2.5.2.9 during the [[***]]period beginning on the Effective Date and Bayer has not acquired any rights under any Other CAR-T prior to such termination, then Atara shall pay to Bayer an amount of [[***]] within [[***]] days of receipt of the relevant invoice from Bayer, which Bayer may submit on or following the date of termination of such Atara obligations. For clarity, any exercised options under Section 2.5.2 (including all subsections thereunder) shall remain unaffected by any termination of the option rights pursuant to this Section 2.5.2.9. For clarity, and without limiting the foregoing, Section 2.5.2 (including all subsections thereunder) does not and will not apply to any grant of rights to any Third Party resulting from a transaction or series of transactions between Atara and any Third Party acquiror that constitutes a Change of Control of Atara, and Bayer will not receive the preferential treatment and option rights contemplated under Section 2.5.2 in any such scenario.

Additional License.  To the extent Bayer wishes to obtain (a) a commercial license under any Know How or Patent Rights Controlled by Atara that is [[***]], or (b) [[***]] under Section 2.1.2, Bayer may, during the term of this Agreement, notify Atara of its desire to enter into negotiations regarding such potential license or expansion by providing written notice to Atara specifying (i) [[***]] or (ii) [[***]] license under the Know How granted to Bayer and its Affiliates under Section 2.1.2, as applicable. Upon Atara’s receipt of any such notice and if Atara so agrees in its sole discretion, the Parties shall discuss the terms of a possible license agreement with respect to the relevant intellectual property rights for which Bayer has requested a license.

Subject to Article 7, which covers the CMC/manufacturing process transfer, within [[***]] days of the Effective Date, Atara shall, and shall cause its Affiliates to, [[***]] deliver to Bayer and / or its designated Affiliate or Sublicensee, in a mutually agreeable form, copies of all written, graphic or electronic embodiments of the Licensed Technology and related Complete Invention Disclosures as well as all cell therapeutics and other materials pertaining to [[***]] for Exploiting Licensed Cell Therapeutics and Licensed Products (hereinafter the “Materials”), [[***]].

Thereafter, on a continuing basis during the term of this Agreement, Atara shall, [[***]] and shall cause its Affiliates to, as soon as reasonably practicable disclose and deliver to Bayer and / or its designated Affiliate or Sublicensee, as soon as reasonably practicable, in a mutually agreeable form, copies of all written, graphic or electronic embodiments of all additional Licensed Technology and / or Complete Invention Disclosures and of all Material which comes into existence from time to time, [[***]].

Without prejudice to the generality of Sections 2.6.1 and 2.6.2, until [[***]] Atara shall, [[***]] at the Atara FTE Rate for each additional FTE hour, provide Bayer or its

designated Affiliate or Sublicensee with reasonable technical assistance relating to the use of the Licensed Technology for the purposes of transferring the Licensed Technology from Atara to the applicable Bayer Party, for the purposes of the applicable Bayer Party’s acquisition of expertise on the practical application of the Licensed Technology or for the provision of assistance to the applicable Bayer Party on issues arising from time to time during any Exploitation of the Licensed Technology, e.g. with respect to [[***]]. If visits of Atara’s representatives to the facilities of the applicable Bayer Party are requested, Atara shall send appropriate representatives to such facilities, provided that Bayer shall reimburse Atara for its reasonable and verifiable out-of-pocket expenses of travel and accommodation for such representatives that have been pre-approved by Bayer in writing.

Each Party shall maintain and make available for the Collaboration Activities all laboratories, offices and other facilities that are necessary to carry out its responsibilities under the relevant Collaboration Activities pursuant to the relevant Collaboration Plan.  

Reports.

Each Party shall submit to the other Party reports on its activities under each of the (a) Research Activities and (b) CMC Activities, and shall provide to the other Party deliverables of such activities, each with information, frequency, within the timelines and with a format as specified in the relevant Collaboration Plan.

In addition, each Party’s Alliance Manager shall, with respect to each of the (a) Research Activities and (b) CMC Activities,

provide the members of the JSC with written updates regarding its Party’s activities under the relevant Collaboration Plan, including summary results and analyses thereof, prior to each JSC meeting; and

Place of Performance. Atara shall perform those parts of the Collaboration Activities that it is responsible for exclusively at [[***]]; as applicable.  

Subcontracting. Atara shall not subcontract any parts of the Collaboration Activities to any Third Party without the prior written consent of Bayer. Bayer, however, hereby consents to Atara’s Affiliates and, solely with respect to activities that MSK is responsible for pursuant to the ATA2271 Plan, to MSK acting as subcontractors of Atara. In case of any written consent of Bayer, if required, to the use of a specific subcontractor for a specific activity, unless explicitly otherwise agreed, the consent will be deemed given under the condition that such contractor of the other Party enters or has entered into an agreement obligating such contractor to all confidentiality, publication and intellectual property-related provisions of this Agreement, applicable to Atara. Each Party shall be solely responsible for the supervision and direction of contractors performing activities designated as such Party’s task under the Collaboration Plan and shall be solely liable for the performance of such activities by such contractors in compliance with this Agreement. Atara will impose on any subcontractor who supplies drug product or any parts thereof sustainability obligations that are substantially equivalent to the sustainability requirements specified in the Bayer Supplier Code of Conduct, which is attached hereto as Exhibit 3.3.6 (the “Bayer Supplier Code of Conduct”).

Each Party agrees to perform all its activities within the Collaboration Activities in good scientific manner and to comply with all Laws applicable to the performance of the activities that it is responsible for under the Collaboration Plans.

Neither Party shall use in any capacity the services of anyone debarred, disqualified, blacklisted or banned or under investigations or threat of investigations by any regulatory authority for debarment, disqualification, blacklisting or any similar regulatory action in any jurisdiction anywhere in the world. Furthermore, each Party represents and warrants that neither such Party nor its employees, agents or representatives involved in the performance of the Collaboration Activities have been debarred, disqualified, blacklisted or banned by any regulatory authority, nor are they currently, to such Party’s Knowledge, the subject of such a debarment, disqualification, blacklisting or banning proceeding. During the term of the Agreement, each Party shall promptly notify the other Party should it or any of its employees, agents or representatives involved in the performance of the Collaboration Activities become the subject of such debarment, disqualification, blacklisting or banning proceeding.

Atara is expected to [[***]] organize its activities under the Collaboration Plans in a manner that [[***]] in line with the Bayer Supplier Code of Conduct, provided that in the event of any conflict between the Bayer Supplier Code of Conduct and a Collaboration Plan, the Collaboration Plan shall govern. Bayer shall have the right to audit the sustainability performance of Atara, either by written assessment (online, paper

questionnaire, etc.) or, upon reasonable advance written notice, by an onsite audit conducted at a mutually agreeable time and in a mutually agreeable manner, executed directly by Bayer or by a Third Party auditor reasonably acceptable to Atara, provided that any such Third Party auditor has entered into an agreement obligating such Third Party auditor to all confidentiality, publication and intellectual property-related provisions of this Agreement, applicable to Bayer. The sustainability performance will be evaluated by comparing it with the Bayer Supplier Code of Conduct principles.

Material Transfer.

From time to time, Bayer may transfer materials to Atara for purposes of the Collaboration Activities.  

Atara understands that materials transferred by Bayer are experimental in nature and Bayer does not make any representation or warranty, express or implied, as to the identity, ownership, purity, utility, safety or activity of such biological materials.  

Atara shall use Bayer’s materials only for the purposes of performing its obligations or exercising its rights under this Agreement. Atara shall not reverse engineer or analyze (except to the extent expressly permitted in the Collaboration Plan and then only for the purposes of the Collaboration Activities) the material or otherwise attempt to determine the identity, structure, or composition of the material, nor will Atara permit or assist others to do so.  

Atara shall not transfer Bayer’s material to any Third Party, except to contractors or collaborators of Atara for the purposes authorized by this Agreement upon prior written notice of such transfer to Bayer.  

Any revision or expansion to the Collaboration Plan that may be requested by either of the Parties during the relevant Collaboration Term shall be discussed by the JSC. This includes, without limitation, discussions regarding the effect any such requested revision or expansion will have on the deliverables (including timing) to be provided under the relevant Collaboration Plan and the allocation of Atara’s and / or Bayer’s resources for performance of its activities under the relevant Collaboration Activities.

The JSC shall have the authority to amend the relevant Collaboration Plan per such Party’s request, and such amendment shall be incorporated into the relevant Collaboration Plan by reference. For clarity, this does not include any right of the JSC to change any terms of this Agreement other than solely within the relevant Collaboration Plan.

Alliance Sponsors. Each party shall designate an executive as sponsor for the alliance (each such executive, an “Alliance Sponsor”). The Alliance Sponsors shall meet and confer as often as they deem appropriate to maintain the health, priority, and direction of the relationship and to proactively solve issues as necessary. The initial Alliance Sponsor designated by Atara is the Vice President, Corporate Strategy and Business Development of Atara, and the initial Alliance Sponsor designated by Bayer is the Vice President, Head of Oncology Strategy & Early Commercialization of Bayer.

Alliance Managers. As soon as practicable after the Effective Date, each Party shall nominate a representative to act as its alliance manager under this Agreement (the “Alliance Manager”). The Alliance Managers shall serve as the key contact point between the Parties. Each Alliance Manager shall be a permanent non-voting member of the Joint Steering Committee and any subcommittee(s).  A Party may replace its Alliance Manager at any time by providing written notice to the other Party.

Joint Steering Committee. Within [[***]] days after the Effective Date the Parties shall establish a joint steering committee (the “Joint Steering Committee” or “JSC”).

Composition. The JSC shall be composed of an equal number of representatives [[***]] from each Party plus the Alliance Manager(s) in a [[***]] capacity. Each JSC representative shall have appropriate experience, knowledge and authority within such Party’s organization to carry out the duties and obligations of the JSC. Each Party shall name its initial JSC representatives and designate one of its representatives as the co-chair (each, a “Co-Chair”) for that Party.

Responsibilities of the JSC. The JSC provides strategic direction and operational oversight to the Alliance, evaluates performance, recommends corrective action and shall act as the point of escalation for issues that cannot be resolved at subcommittee or sub-team levels. Within [[***]] days of the execution of the agreement, the JSC shall jointly establish a charter (the “JSC Charter”) that details specific responsibilities and such JSC Charter will be updated annually to ensure it is focusing on key activities and contractual obligations. Initial considerations for the JSC Charter include:

monitoring performance of this Agreement as well as progress of the Collaboration Activities compared to the goals defined in the Collaboration Plans and deciding on corrective action, where required;

serving as the principal means by which each Party keeps the other Party informed about the status of those parts of the Collaboration Activities within its responsibilities;

reviewing and discussing as to whether the deliverables have been achieved;

agreeing on changes to the existing Collaboration Plans - including, with respect to the Research Plan in the event of [[***]] - in each case, which do not materially increase or decrease Atara’s or Bayer’s obligations, provided that, for clarity, the JSC shall not have the authority to [[***]];

recommending modifications to the Collaboration Plan which materially increase or decrease Atara’s or Bayer’s obligations, or any other amendments to this Agreement;

agreeing on changes to the ATA2271 Plan, which changes shall be subject to MSK approval prior to taking effect, provided that Atara shall use reasonable efforts to obtain such MSK approval;

identifying the Bayer Background Technology, if any, to be used in connection with the Collaboration Activities;

This includes that Atara will submit to Bayer all Regulatory Documentation and all other study data relating to the ATA2271 Phase 1 Clinical Trial within due course, but in no event later than within [[***]] Business Days after such documents and data are received or generated by Atara. Upon request of Bayer, Atara will enable Bayer scientists to participate as observing members in any material development-related activities of Atara and to the extent that Atara has the right to do so, any material development-related activities of MSK, said participation being subject to MSK’s approval. Atara will [[***]] obtain such approval from MSK and will, upon Bayer’s written request, inform Bayer about the steps taken to obtain such MSK approval and the status of the approval process.

After completion of [[***]], Bayer shall be solely responsible, at its sole discretion, for continuing the ATA2271 clinical development and Atara will take all steps reasonably required to enable Bayer to take over such program in a mutually agreeable manner.

For clarity, all materials, documents and data generated within the ATA2271 clinical development, as described above, form part of the Licensed Technology and, consequently, Bayer has the exclusive right to use such materials, documents and data for Exploitation of Licensed Cell Therapeutics and Licensed Products in the Field in the Territory.

Bayer shall use Commercially Reasonable Efforts to Develop [[***]] in each of the Major Market countries. For clarity, Bayer shall not have any Development obligations for any additional indication or in any other country.

Right of Reference for Atara. Atara and its Affiliates and their designees will have, and Bayer (on behalf of itself and its Affiliates) hereby grants, and shall cause all other Bayer Parties to grant, to Atara and its Affiliate and their designees, access and a “Right of Reference or Use” as that term is defined in 21 C.F.R. § 314.3(b) (without any further

action required on the part of Atara, its Affiliates or contractors, whose authorization to file this consent with any Regulatory Authority is hereby granted) in connection with the development of products of Atara and its Affiliates to all Regulatory Documentation relating to any Licensed Cell Therapeutic or Licensed Product, or any components thereof, controlled by or on behalf of any Bayer Parties and all data contained or referenced therein, and agrees to sign and cause the other Bayer Parties to sign, any instruments reasonably requested by Atara in order to effect such grant.

Right of Reference for Bayer. Atara hereby grants and shall [[***]] cause MSK and Atara’s and MSK’s Affiliates grant to Bayer Parties a “Right of Reference or use” as that term is defined in 21 C.F.R. § 314.3(b), without any further action required on the part of Bayer Parties or their contractors (whose authorization to file this consent with any Regulatory Authority is hereby granted), in connection with the development of Licensed Cell Therapeutics or Licensed Products to all Regulatory Documentation relating to ATA2271 or any components thereof and all data contained or referenced therein, and agrees to sign, and shall [[***]] cause MSK and Atara’s and MSK’s Affiliates to sign, any instruments reasonably requested by Bayer Parties in order to effect such grant.  If Bayer wishes to obtain a “Right of Reference or use” to any other regulatory filing Controlled by Atara, Bayer shall so notify Atara in writing, and, provided that Atara has the rights necessary to grant Bayer any such rights and that such additional Right of Reference or use is reasonably required to Develop the Licensed Cell Therapeutic or Licensed Product without any unnecessary delay or significant additional cost, Atara shall consider, in good faith, Bayer’s request for an additional grant of such rights to Bayer and shall not unreasonably withhold its consent to such request.

Responsibility. Subject to the terms and conditions of this Agreement, Bayer shall be solely responsible for the Commercialization of the Licensed Product in the Field in the Territory at Bayer’s sole expense (except as set forth elsewhere in this Agreement), including, for the avoidance of doubt, the planning and implementation, distribution, booking of sales, pricing and reimbursement, in all cases, whether performed by or on behalf of Bayer or any other Bayer Party or Third Party appointed by Bayer.

Reporting on Milestone Achievement and Payment. Bayer shall provide written notice to Atara of (a) any occurrence of any of the development milestones set forth above no later than [[***]] days following the occurrence of the relevant milestone, and (b) any occurrence of any of the sales milestones set forth above with the royalty report to be provided by Bayer for the respective Quarter pursuant to Section 9.5.5, and shall, upon receipt of an invoice pursuant to Section 9.6, make the associated milestone payments in accordance with Section 9.6.

Limitation on Milestones. For the avoidance of doubt:

The Development and Regulatory Milestones are intended to be successive on a country-by-country or region-by-region basis, as applicable; in the event that Bayer skips any of such milestones on a country‑by-country or region-by-region basis, as applicable, Bayer shall be deemed to have achieved such skipped milestone when it achieves the next successive Development and Regulatory Milestone for the relevant Licensed Product.  

No milestone payment will be made more than once per Licensed Product (as opposed to another Licensed Product);

No additional milestone payments shall be due in respect of subsequent or repeated achievements of any milestone(s), irrespective of the number of countries in which such milestone has been achieved, or in respect of any further indications not explicitly specified within the milestones listed under Section 9.4.1 and 9.4.2 above;  

No additional milestone payments shall be due in respect of any Combination Licensed Product where the milestone has already been paid on a Licensed Product; and

No Valid, Practiced Claim. If, during the Royalty Term, in any particular country in the Territory, a Licensed Product is not covered or claimed by a Valid, Practiced Claim, then the royalties that would otherwise have been payable on Net Sales of such Licensed Product in such country under this Agreement shall be reduced by [[***]] percent [[***]] as from the first Quarter in which there is no Valid, Practiced Claim. The calculation of the royalty reduction shall be conducted separately for each Licensed Product in each country.

Compulsory Licenses. [[***]].

Biosimilar Product. [[***]].

Third Party Technology. Subject to the last sentence of this Section 9.5.3.4, if during the term of this Agreement Atara or Bayer becomes aware of a Third Party Patent Right (excluding for clarity any Patent Rights controlled by MSK) and where Bayer reasonably determines, in the absence of a license to such Third Party Patent Right, such Third Party Patent Right would be infringed by the Exploitation of the Licensed Cell Therapeutic and / or Licensed Product (solely to the extent consisting of an Atara Cell Therapeutic), Bayer (itself or through any other Bayer Party) may obtain a license to such Third Party Patent Right in any country in the Territory. Atara agrees to fully co-operate with Bayer in any licensing of such rights by Bayer, as Bayer may reasonably request. In the event that Bayer pays any [[***]] in consideration solely for a license to such Third Party Patent Right for the Exploitation of the Licensed Cell Therapeutic and / or Licensed Product (solely to the extent consisting of an Atara Cell Therapeutic) (subject to the limitation specified in sentence 1 of this Section 9.5.3.4), as applicable, [[***]]payable by Bayer to Atara pursuant to Section 9.5.1 shall be reduced by [[***]] percent [[***]] of the amounts actually paid to such Third Party in such country as consideration solely for any such license to such Third Party Patent Rights for such purpose.

For clarity, Atara shall be solely responsible to cover any third party royalty obligations that Atara may have under the Existing Agreements in relation to this license.

Notwithstanding anything to the contrary in this Agreement, in no event shall the royalties payable to Atara under Section 9.5.1 be reduced to less than:

[[***]]

Royalty Reporting. Starting from the date of First Commercial Sale of the Licensed Product(s) in any country, Bayer shall submit within [[***]] days after the end of each Quarter a good faith, non-binding, preliminary indication of Net Sales achieved within the previous Quarter (such preliminary indication not including any further breakdown, e.g., into countries, Licensed Products). Within [[***]] days of the end of each Quarter, Bayer shall prepare and deliver to Atara a written statement setting forth:

Net Sales for that Quarter on a Licensed Product-by-Licensed Product and country-by-country basis;

[[***]]; and

[[***]];

[[***]]; and

the associated royalties due to Atara.  

Currency. All payments under this Agreement will be made in U.S. dollars. Where the payments due are calculated based on a currency other than U.S. dollars, the amount due will be converted to U.S. dollars using the average quarter to date exchange rate for the applicable quarter as consistently applied per Bayer’s internal accounting and reporting process.

Payment Date. The License Upfront Payment, the Reimbursement Upfront Payment, any and all royalties owing from Bayer to Atara under Section 9.5 and the payments owing from Bayer to Atara under Section 9.3, shall be paid by Bayer to Atara within [[***]] days after receipt of invoice, and the milestone payments and any other payment by Bayer shall be made within [[***]] days after receipt of invoice (each a “Payment Date”).

All payments due to Atara under this Agreement shall be paid upon the receipt of a respective invoice in U.S. dollars by wire transfer to the following bank account, or to such other bank account specified, at least [[***]] Business Days prior to the applicable Payment Date, in writing by Atara to Bayer:

Late Payments. All payments not made by [[***]] days after the respective Payment Date set out in this Agreement shall be subject to Late Payment interest at the United States Secured Overnight Financing Rate (SOFR), currently published on Bloomberg screen <SOFRRATE Index>, fixed [[***]] Business Days prior to the respective Payment Date and reset to the prevailing [[***]] month SOFR at monthly intervals thereafter, plus a premium of [[***]] (or the maximum applicable legal rate of interest if lower). Interest shall be calculated based on the actual number of days in the interest period divided by 360 and shall be calculated from the respective Payment Date (inclusive) until the date of payment (exclusive).

All agreed consideration is exclusive of Value Added TAX (“VAT”). If legally applicable, VAT will be invoiced and has to be paid additionally after receipt of a proper invoice, which meets all legal requirements according to the applicable VAT-law.

Any party required to make a payment pursuant to this Agreement shall be entitled to deduct and withhold from the amount payable the tax for which paying party on behalf of payee is liable under any provisions of tax law. If the withholding tax rate is reduced according to the regulations in the Double Tax Treaty no deduction shall be made or a reduced amount shall be deducted only if paying party is timely furnished with necessary documents by payee issued from the relevant tax authority, certifying that the payment is exempt from tax or subject to a reduced tax rate. Except as otherwise provided in Section 9.6.3, any withheld tax shall be treated as having been paid by paying party to payee for all purposes of this Agreement. Paying party shall timely forward the tax receipts

certifying the payments of withholding tax on behalf of payee. In case paying party must pay, but cannot deduct the withholding tax due to fulfillment and completion of payment obligation by settlement or set-off, payee will pay the withholding tax to the paying party separately. If paying party failed to deduct withholding tax but is still required by tax law to pay withholding tax on account of payee to the tax authorities, payee shall assist paying party with regard to all procedures required in order to obtain reimbursement by tax authorities or, in case tax authorities will not reimburse withholding tax to paying party, payee will immediately refund the tax amount.

Notwithstanding the foregoing, if (a) any party redomiciles or assigns its rights or obligations under this Agreement, (b) as a result of such redomiciliation or assignment, such Party (or its assignee) is required by Law to withhold taxes, or such redomiciliation or assignment results in the imposition of indirect taxes that were not otherwise applicable, from or in respect of any amount payable from such party to the other party under this Agreement, (c) the other Party is despite reasonable efforts not able to obtain an exemption or reduction from such additional tax; and (d) such withholding taxes or indirect taxes which cannot be exempted from tax by the other Party with reasonable efforts exceed the amount of withholding taxes or indirect taxes that would have been applicable had such redomiciliation or assignment not occurred, then any such amount payable shall be increased to take into account such withholding taxes or indirect taxes as may be necessary so that, after making all required withholdings (including withholdings on the additional amounts payable) and / or paying such indirect taxes, as the case may be, the payee party (or its assignee) receives an amount equal to the sum it would have received had no such increased withholding been made and no such Indirect Taxes had been imposed.  The obligation to pay additional amounts pursuant to the preceding sentence shall not apply, however, to the extent such increased withholding tax or indirect taxes would not have been imposed but for the assignment by the payee party of its rights or obligations under this Agreement or the redomiciliation of such payee party outside of the United States.

with respect to Licensed Products that are covered by Licensed Patents under the MSK MSLN License and/or that are containing, derived from or made using BioVec Products (as such term is defined in the BioVec Upstream License), [[***]] years;

Details of the auditor’s findings (including, for the avoidance of doubt, monetary values and supporting calculations) shall not be shared with Atara except in the form of a summary report (and, in any event), the summary report shall be communicated to Bayer before being shared with Atara and Bayer shall be given a period of [[***]] Business Days to review and respond to the auditor’s findings before the summary report may be provided to Atara (such reports to include Bayer’s response to the findings);

The auditor shall not be permitted to include any extrapolation calculations in their calculation of amounts allegedly underpaid to Atara;

If an audit reveals that Bayer has underpaid royalties due, Atara may invoice Bayer for the underpaid amount;

If an audit reveals an underpayment in excess of [[***]] percent [[***]] of the fees for the period subject to review by Atara, then Bayer shall pay the reasonable costs of the auditors within [[***]] days of Atara’s receipt of the summary report in Section 10.2.5

notifying Bayer that the audit has been completed; for clarity, any underpayment shall be subject to Late Payment interest in accordance with Section 9.6.4; and

If an audit reveals that Bayer has overpaid any royalties (the amount of each such overpayment, an “Overpayment Amount”), then, as may be requested by Bayer, (i) the Overpayment Amount will be credited against any future amounts payable to Atara by any Bayer Party, or (ii) Atara shall reimburse Bayer for such Overpayment Amount (or any portion thereof that has not been credited as set out in the foregoing clause within [[***]] days after the date such auditor reveals to any Bayer Party, or any Bayer Party reveals to Atara, such Overpayment Amount; for clarity, no interest shall become due on the Overpayment Amount from the date such payment was received by Atara until the due date after the overpayment was revealed.

Intellectual Property owned by Bayer.  

As between the Parties, Bayer will retain all right, title and interest in and to, and shall [[***]] own, [[***]]Bayer Results, Joint Results, Bayer Background Technology and Bayer Background Improvements.

To the extent any copyrights constituting Bayer Background Improvements generated in whole or in part by Atara or any Joint Results, cannot be assigned by Atara to Bayer under applicable Law, Atara hereby grants Bayer an exclusive, irrevocable, perpetual, fully paid-up, royalty-free, world-wide license, with the right to grant sublicenses, to Exploit such copyrights and Joint Results for any and all purposes.

No right or license is granted to Atara hereunder with respect to any Bayer Results, Bayer Background Technology, Bayer Background Improvements other than the licenses and rights granted to Atara pursuant to Article 2.

For clarity, as between the Parties, Bayer shall [[***]] own all intellectual property rights conceived and reduced to practice in the conduct of Bayer’s activities [[***]] in exercise of the licenses granted by Atara to Bayer under this Agreement (such intellectual property rights, the “Bayer Improvement IP”) and Bayer may file, prosecute, maintain and enforce Patent Rights on such Bayer Improvement IP as it deems appropriate.

Cooperation and Support. If and as may be reasonably requested by the other Party, each Party shall (and shall, as applicable, cause each of its employees, officers, directors, consultants or contractors to) duly execute and deliver (or cause to be duly executed and delivered) such agreements and other documents, including assignment agreements, and take such further actions (or cause such further actions to be taken), to make such assignment(s) as may be reasonably necessary or desirable to effect the ownership rights set out in this Section 11.2 and to evidence, confirm, record and perfect any such assignment(s).

Bayer shall have the first right, but not the obligation, to prepare, file, prosecute and maintain the Joint Results Patents worldwide.  Bayer shall keep Atara reasonably informed of all material steps with regard to the preparation, filing, prosecution and maintenance of the Joint Results Patents, including by providing Atara with a copy of material communications to and from any patent authority in the Territory regarding such Joint Results Patents, and Atara shall be copied on all material correspondence with Bayer’s patent counsel with respect thereto.  Bayer shall provide Atara drafts of any material filings or responses to be made to such patent authorities in the Territory in advance of submitting such filings or responses so as to allow for a reasonable opportunity for Atara to review and comment thereon, and Bayer shall consider in good faith and discuss Atara’s requests and suggestions with respect to Bayer’s drafts and with

respect to strategies for filing and prosecuting the Joint Results Patents.  Bayer shall consult with Atara reasonably prior to (but at least [[***]] days prior to) taking or failing to take any substantive action (including making any filings) with respect to the Joint Results Patents, including any action that would materially affect the scope or validity of rights under any patent applications or patents with the Joint Results Patents (such as substantially narrowing or canceling any claim without reserving the right to file a continuing or divisional patent application, abandoning any patent or not filing or perfecting the filing of any patent application in any country).  If Bayer decides not to prepare, file, prosecute or maintain a Joint Results Patent in a country in the Territory, Bayer shall provide reasonable prior written notice to Atara of such intention (which notice shall, in any event, be given no later than [[***]] days prior to the next deadline for any action that may be taken with respect to such Patent Right in such country), Atara shall thereupon have the option, in its sole discretion to assume the control and direction of the preparation, filing, prosecution and maintenance of such Joint Results Patent.  Upon Atara’s written exercise of such option, Atara shall assume the responsibility and control for the preparation, filing, prosecution and maintenance of such Joint Results Patent.  In such event, Bayer shall promptly provide Atara with the appropriate documents for such transfer of responsibility and control and reasonably cooperate with Atara in such country, including by (i) executing all papers and instruments, or requiring its employees or contractors to execute such papers and instruments, so as to enable Atara to apply for and to prosecute the Joint Results Patents in the Territory, and (ii) promptly informing Atara of any matters coming to Bayer’s attention that may materially affect the preparation, filing, prosecution or maintenance of any such Joint Results Patent.  The Parties shall [[***]] costs associated with filing and prosecuting the Joint Results Patents.

Atara shall be responsible, and [[***]] to file, prosecute and maintain the Licensed Patent Rights, through a qualified and recognized patent counsel, at least in the countries listed in Exhibit 11.6.1, and shall [[***]].  Atara shall inform Bayer of any materially relevant communication with patent offices relating to the filing, prosecution or maintenance of such Licensed Patent Rights. Furthermore, Atara shall provide Bayer with copies of any materially relevant documents or correspondence with patent offices or any other documents which may be important for any action to be taken in a timely manner and no less than [[***]] days prior to any relevant deadline, provided such time is available. Bayer shall communicate its comments on the same to Atara on the earlier of: [[***]] days from the date the information was received by Bayer; and no less than [[***]] days before the deadline, or intended deadline, for the action to be taken, provided that such period is available, and Atara shall consider in good faith the comments provided by Bayer.

If Atara determines that it is not commercially reasonable to file, nationalize (if applicable) or further prosecute a Licensed Patent Right in any country listed in Exhibit 11.6.1, Atara shall provide reasonable advance written notice (“Cessation Notice”) to Bayer of such determination (which notice shall, in any event, be given no later than [[***]] days prior to the next deadline for any action that may be taken with respect to such Licensed Patent Right in such country). Upon receipt of such notice, Bayer may

object to such determination within [[***]] days and request that Atara continue filing or prosecuting such Licensed Patent Right. If the Parties cannot agree upon whether Atara will or will not continue to file or prosecute such Licensed Patent Right, such dispute will be referred to the [[***]] for dispute resolution in accordance with Section 20.1. During the dispute resolution process, Atara will continue to file and / or prosecute, as applicable, such Licensed Patent Right at Atara’s cost.  If, following dispute resolution in accordance with Section 20.1, the Parties determine that Atara’s decision was appropriate, Bayer will [[***]] with the filing and / or prosecution of such Licensed Patent Right following Atara’s delivery of the applicable Cessation Notice to Bayer.

The Parties acknowledge and agree that this Section 11.6 is subject to the terms and conditions of the Existing Agreements, but solely with respect to those Patent Rights within the Licensed Patents Rights that are owned by MSK or NIH and licensed to Atara under the Existing Agreements.

Notice. If any Licensed Patent Right is or might be infringed by a Third Party making, using or selling a Competing Product in the Field (each a “Field Infringement”), the Party first having knowledge thereof shall promptly notify the other Party in writing. Such notice shall set forth the facts of the Field Infringement in reasonable detail.

Enforcement.

Atara shall have the first right (but not the obligation), by counsel of its own choice and at its sole expense, to institute, prosecute and control the enforcement or defense of Licensed Patent Rights, except that, subject to Section 2.1.3  of this Agreement, Bayer shall have the first right (but not the obligation), by counsel of its own choice and at its sole expense, to institute, prosecute and control the enforcement of any Licensed Patent Rights within the Exclusive Technology against any Field Infringements. Prior to undertaking any such action to enforce or defend such Licensed Patents Rights, the Party controlling the suit or action (“Prosecuting Party”) shall notify the other Party in writing. If the Prosecuting Party requests that the other Party join any such action, the other Party shall do so and the other Party hereby agrees that counsel for the Prosecuting Party shall also represent the other Party in such action. The other Party shall have the right, at its own expense, to also be represented in any action by counsel of its own choice. For the avoidance of doubt, should the other Party partake in any such action brought by the Prosecuting Party, either at the Prosecuting Party’s request or otherwise, the Prosecuting Party shall retain control of the proceeding and shall have [[***]]related thereto.

In the event that the Party with the first right to enforce determines not to make use of its right to institute an action or proceeding or otherwise take appropriate action to enforce or defend Licensed Patent Rights, then such Party shall provide written notice to the other Party that it declines such right as to such activity as soon as reasonably practicable, but in no event later than [[***]] days

after notice by the other Party requesting action, or within [[***]] days prior to any deadline associated with the defense or enforcement of the Licensed Patent Rights (which deadline has been previously communicated to the other Party), and after receiving such notice, subject to Section 2.1.3 of this Agreement, the other Party shall have the right (but not the obligation) to institute and / or prosecute and control such an action or proceeding in its name with respect to such enforcement or defense at its sole expense and by counsel of its own choice, and the non‑Prosecuting Party shall have the right to be represented in any such action by counsel of its own choice and at its own expense. The Parties shall reasonably cooperate with each other in the planning and execution of any such action to enforce or defend such Licensed Patent Rights and shall [[***]].

The Parties agree to cooperate fully in any action or proceeding for a Field Infringement, as applicable, pursuant to Sections 11.7.2.1 or 11.7.2.2.  If a Party brings such an action or proceeding, such Party shall (a) keep the other Party reasonably informed of all material steps proposed to be taken, and provide copies of all material documents filed or received (to the extent permitted), in connection with the Licensed Patent Rights, as applicable, in such action or proceeding, and (b) consider in good faith any comments from the non-enforcing Party with respect thereto.  At the request of the Party bringing such action or proceeding, the other Party shall, where necessary, furnish a power of attorney solely for such purpose or shall join in, or be named as a necessary party to, such action or proceeding.  Bayer shall not settle any action or proceeding in accordance with Sections 11.7.2.1 and 11.7.2.2 with respect to a Field Infringement without the prior written approval of Atara, not to be unreasonably withheld, conditioned or delayed; provided, however, in all cases, Bayer shall not have the right to settle such action or proceeding in a manner that involves an admission of invalidity or unenforceability with respect to any Licensed Patent Rights, without the prior written consent of Atara, such consent to be granted or withheld in Atara’s sole discretion. Without limiting the foregoing, if either Party initiates an action or proceeding pursuant to Sections 11.7.2.1 or 11.7.2.2, such Party shall provide the other Party with copies of all pleadings and other documents filed with the court.

All monies recovered upon the final judgment or settlement of any such suit or action to enforce the Licensed Patent Rights against a Field Infringement in the Field in the Territory shall be applied in the following order of priority: (x) first, the Party bringing suit or action shall be reimbursed for all costs and expenses (including reasonable attorney’s fees and costs) incurred in connection with such suit or action, then to the costs and expenses (if any) of the other Party; and (y) thereafter, any remainder shall be shared as follows: [[***]] to Bayer and [[***]] to Atara.

Enforcement Outside Scope of Exclusive License. For the avoidance of doubt, Atara shall have the right (but not the obligation), at its sole expense and sole discretion, to control the enforcement or defense of the Licensed Patent Rights to abate any infringement other than a Field Infringement. Atara shall, however, in any such action coordinate and reasonably cooperate with Bayer with the intent to ensure that any position taken, and / or

arguments made, by Atara (e.g., claim constructions) do not adversely impact any of the Licensed Patent Rights or any of Bayer’s rights or licenses hereunder.

Patent Challenge. To the extent permitted by Laws on a country-by-country basis, Bayer agrees (i) not to challenge the validity or enforceability of any claim within the Licensed Patent Rights that are subject to the MSK Upstream Licenses, (ii) [[***]].

General aspects.

Each party shall comply with their respective obligations under applicable data privacy laws.

Data privacy related terms shall have the meaning as defined in Art. 4 General Data Protection Regulation EU 2016/679 (GDPR) if not otherwise defined in this Agreement.

The Parties acknowledge that they will need to process personal data of the respective other Party’s employees (“Employee Data”) for the purpose of executing this contract.

In the context of this Agreement, a Party may need to transfer human biological samples (including any derivatives or progeny thereof like cell lines) (“Human Samples”) including information regarding the origin, pathology or integrity of such samples and/or other research related data (including information about health) on a one-person-level to the respective other Party. Such data, and/or the results of analyses of said human biological samples, may qualify as personal data (in this case: “Human Data”). For the avoidance of doubts, one-person-level data may qualify as personal data (if it falls under the definition of personal data in applicable data privacy law) but does not necessarily do so.

Privacy obligations of Disclosing Party.

Where a Party discloses Human Samples and/or Human Data to the respective other Party, the disclosing Party is responsible to ensure meeting all conditions that are legally required to allow this disclosure for purposes of this Agreement (including medical and diagnostic research and development purposes). This may include e.g. ensuring that respective data subjects have given and not withdrawn their consents, or anonymizing or de-identifying Human Samples and/or Human Data prior to disclosure (examples not exhaustive).

In case a transfer of Human Samples and/or Human Data from Bayer to Atara is required, the Parties hereby enter by reference the standard contractual clauses as published by the European Commission as Decision 2004/915/EC. Atara as data importer will process personal data in scope of the standard contractual clauses according to Annex A of the standard contractual clauses. Specifications required for annex B are as follows:

Data subjects: Participants of clinical studies, donors of human samples

Purposes of transfer: Purposes as specified in the Agreement

Category of data: Human Samples and/or Human data collected as part of clinical studies or obtained for research purposes

Recipients: Atara

Sensitive data: Data about health, genetic data

Contact point for data protection inquiries:
Data importer: [[***]]
Data exporter: [[***]]

Each Parties confirms that at time of signature of this Agreement, it is not aware of any legal requirement that may hinder disclosing Human Samples and/or Human Data to the respective other Party as required to fulfill the obligations under this Agreement.

The Party disclosing Human Data to the other Party shall do so only encrypted or via secure communication channels.

Privacy obligations of Receiving Party.

The Party receiving Employee Data and Human Samples and/or Human Data from the respective other Party may only use those as required for purposes of this Agreement.

Whenever Atara (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) provides to Bayer, pursuant to this Section 18.5, any of the Licensed Technology and embodiments of Licensed Technology in accordance with this Agreement, Bayer shall have the right to perform the obligations of Atara hereunder with respect to such Licensed Technology and embodiments of Licensed Technology, but neither such provision nor such performance by Bayer shall release Atara (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) from liability

resulting from any rejection of the license or the failure to perform such obligations set forth in this Agreement.
