Page 19

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.

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.

2.5.2.13 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

Page 21

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.

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.

2.6 Technology Transfer.

2.6.1 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”), [[***]].

Page 22

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.

2.7 Good Faith Efforts to Control Required Intellectual Property.

Notwithstanding Section 9.4.5.1, in the event a Phase 2 Clinical Trial seeking accelerated Regulatory Approval is initiated, the milestone payments under [[***]] shall be due upon the earliest of [[***]]. Bayer shall provide written notice to Atara of any of the events described in clauses (a) – (c) of the preceding sentence within [[***]] days following the occurrence of the relevant event.

For clarity, any inference or reference to a “first, “second” or “third” Tumor Type above, shall be construed to mean the “first”, “second” or “third” Tumor Type that achieves the applicable milestone event, regardless of how many other Tumor Types have been previously pursued with respect to the same or other Licensed Products without achieving the applicable milestone event; this means, [[***]].

In the event that [[***]], Atara is entitled to invoice an amount of [[***]] to Bayer together with [[***]]. Bayer shall make such payment within [[***]] days from [[***]]. For clarity, [[***]].  In the event that, following such payment by Bayer, [[***]], then [[***]].

9.4.5 Limitation on Milestones. For the avoidance of doubt:

9.4.5.1 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.  

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

9.4.5.3 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;  

9.4.5.4 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

Page 37

aggregated annual Net Sales of each such Licensed Product sold in the Territory during the Royalty Term in the following amount:

[[***]]

For the avoidance of doubt, the cumulative Net Sales value shall be based on cumulative Net Sales from the start of a Calendar Year and reset on an annual basis.

For the avoidance of doubt, no royalties shall be due or payable on samples of Licensed Product or clinical trial materials or other transfers or dispositions of the Licensed Product for charitable, promotional, pre-clinical, clinical, manufacturing, testing or qualification, regulatory or governmental purposes.

9.5.2 Sublicense Income for an [[***]] Licensed Product. In addition to the associated milestones and royalties outlined above, Bayer shall pay to Atara the following percentage of all Sublicense Income:

9.5.2.1 [[***]] percent [[***]] if at the time of execution of the sublicense agreement the status of the project is [[***]]; or

9.5.3 Reduction in Royalties.

9.5.3.1 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.

9.5.3.2 Compulsory Licenses. [[***]].

9.5.3.3 Biosimilar Product. [[***]].

9.5.3.4 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

Page 38

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.

9.5.3.5 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.

9.5.4 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:

9.5.4.1 [[***]]

9.5.5 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:

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

9.5.5.2 [[***]]; and

9.5.5.3 [[***]];

9.5.5.4 [[***]]; and

9.5.5.5 the associated royalties due to Atara.

Following Atara’s receipt of such quarterly statement, Atara shall deliver to Bayer an invoice for the royalties due to Atara, and upon Bayer’s receipt of such invoice, Bayer shall make the associated royalty payments in accordance with Section 9.6.2.

9.6 Payments.

9.6.1 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.

9.6.2 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”).

Page 39

9.6.3 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:

Account Holder:	[[***]]
Bank Name:	[[***]]
Bank Address, City, and State:	[[***]]
Account No:	[[***]]
Bank Code:	[[***]]
SWIFT (BIC):	[[***]]
Routing Transit Number ABA:	[[***]]
Each invoice for payments shall be sent to:

[[***]]

mentioning such other information required and as may be amended and / or provided by Bayer to Atara from time to time.

Alternatively, each invoice for payments mentioning the aforementioned address and reference may be sent electronically in portable document format (pdf) via email without electronic signature (“pdf-invoicing”), to

[[***]]

thus replacing a corresponding paper form.

9.6.4 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).

9.7 Taxes.

9.7.1 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.

9.7.2 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,

Page 40

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.

9.7.3 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.

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

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

10.2.8 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

10.2.9 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

Page 42

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.

Page 43

prosecute, maintain and enforce Patent Rights on such Bayer Improvement IP as it deems appropriate.

11.2.3 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).

11.5 Filing, Prosecution and Maintenance of Joint Results Patents.

11.5.1 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

Page 44

11.7 Patent Enforcement.

11.7.1 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.

11.7.2 Enforcement.

11.7.2.1 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.

11.7.2.2 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 [[***]].

11.7.2.3 The Parties agree to cooperate fully in any action or proceeding for a Field Infringement, as applicable, pursuant to Sections

Page 46

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.

11.7.2.4 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.

11.7.3 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.

11.7.4 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) [[***]].

11.8 Defense of Third Party Claims. If a Party becomes aware of any actual or potential claim that the Exploitation of any Licensed Cell Therapeutic or Licensed Product or any other use by any person of Licensed Technology infringes the intellectual property rights of any Third Party, such Party shall promptly notify the other Party. (i) Atara shall not acknowledge to a Third Party the validity of any such allegation or admit liability without the prior written consent of Bayer, and (ii) Bayer shall not acknowledge to a Third Party the validity of any such allegation or admit

Page 47

liability without the prior written consent of Atara, in each case (i) and (ii), such consent not to be unreasonably withheld or delayed.

Each Party shall promptly notify the other Party in writing of any written allegation received from a Third Party or Regulatory Authority of an alleged material deviation from applicable Laws with respect to activities under this Agreement. No Party or any of its Affiliates shall, or shall be required to, undertake any activity under or in connection with this Agreement which violates, or which it believes, in good faith, may violate (or cause the other Party to violate), any Law.

17.3 Marking of Licensed Products. With respect to Licensed Products that are subject to the MSK Upstream Licenses, to the extent required by Law, or if the failure to mark would reduce the rights of MSK or Atara to enforce such Licensed Patent Rights against infringers, Bayer shall mark, and shall cause its Affiliates and Sublicensees to mark, such Licensed Products (or the packaging thereof) with the appropriate Licensed Patent Rights.

17.4 Data Privacy.

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.

17.4.2 Privacy obligations of Disclosing Party.

17.4.2.1 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).

In the event that a change in applicable data protection law would require a different transfer mechanism than the standard contractual clauses as published by the European Commission as Decision 2004/915/EC in order to allow an export of personal data from Bayer to Atara, Bayer and Atara shall cooperate in good faith to implement such an alternative prior to the effective date of any such change.

17.4.2.3 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.

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

17.4.3 Privacy obligations of Receiving Party.

17.4.3.1 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.

17.4.3.2 Receiving Party is responsible to meet applicable privacy Laws when using received Human Samples and/or Human Data; receiving Party is in this respect a data controller as defined in the GDPR.

For clarity, the effects of any violation of diligence obligations pursuant to this Agreement will in any event be limited to a right to terminate this Agreement with any other rights (such as damages, specific performance, etc.) being excluded.  

20.4 Disputes Related to Patent Rights. Notwithstanding anything in this Agreement to the contrary, any and all issues regarding the validity and enforceability of any Patent Rights (“Patent Matters”) shall be determined in a court or other tribunal, as the case may be, of competent jurisdiction under the applicable patent laws of the applicable country, with a jury trial being however excluded.  If such dispute involves both Patent Matters and other matters, the arbitrators will have the right to stay the arbitration until determination of Patent Matters material to the resolution of the dispute as to the other matters is resolved.

20.5 Injunctive Relief. Nothing contained in this Agreement shall deny either Party the right to seek injunctive relief, equitable relief, interim or provisional relief including a temporary restraining order, specific performance, preliminary or permanent injunction or other interim equitable relief from a court of competent jurisdiction in the context of a breach or threatened breach of any provision of this Agreement, bona fide emergency or prospective irreparable harm, or as reasonable and necessary to protect its legitimate interests.
