(a)No deduction or withholding for or on account of any tax has been made from any Royalty Payment by Licensee to Seller under the License Agreement, and Seller has not received any written notice from Licensee that any such deduction or withholding will be required or requested in the future.

(b)Seller has filed (or caused to be filed) all material tax returns and material tax reports required to be filed under Applicable Law and has paid all material taxes required to be paid, except for any such taxes that are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with generally accepted accounting principles applicable to Seller, as in effect from time to time.

Purchaser hereby represents and warrants to Seller as of the date hereof as follows and acknowledges that Seller is relying on these representations and warranties in connection with the transactions contemplated by this Agreement:

Purchaser is a limited partnership formed and existing under the laws of the Province of Ontario. Purchaser GP is a corporation duly organized, validly existing and in good standing under the laws of the Province of Ontario and is the sole general partner of Purchaser.

Purchaser GP, in its capacity as general partner of Purchaser, has all powers and authority to execute and deliver, and to perform Purchaser’s obligations under, the Transaction Documents and to consummate the transactions contemplated hereby and thereby. The execution and delivery of each of the Transaction Documents by Purchaser GP, in its capacity as general partner of Purchaser, and the performance by Purchaser of its obligations hereunder and thereunder have been duly authorized by Purchaser GP, in its capacity as general partner of Purchaser. Each of the Transaction Documents constitutes the legal, valid and binding obligation of Purchaser, enforceable against Purchaser in accordance with its respective terms, subject to applicable Bankruptcy Laws, general equitable principles and principles of public policy.

None of the execution and delivery by Purchaser GP, in its capacity as general partner of Purchaser, of any of the Transaction Documents, the performance by Purchaser of the obligations contemplated hereby or thereby or the consummation of the transactions contemplated hereby or thereby will conflict with or result in a breach or default under, (a) any Applicable Law or any Judgment of any Governmental Authority, to which Purchaser or Purchaser GP, in its capacity as general partner of Purchaser, may be subject or bound, (b) any term or provision of any contract to which Purchaser or Purchaser GP, in its capacity as general partner of Purchaser, is a party or (c) any term or provision of any of the organizational documents of Purchaser or Purchaser GP.

The execution and delivery of the Transaction Documents by Purchaser GP, in its capacity as general partner of Purchaser, the performance by Purchaser of its obligations hereunder and thereunder and the consummation by Purchaser of any of the transactions contemplated hereunder and thereunder do not require any consent, approval, license, order, authorization or declaration from, notice to, action or registration by or filing with any Governmental Authority having jurisdiction over Purchaser or Purchaser GP, except for those that have been previously obtained or made.

There is no action, suit, arbitration proceeding, claim, demand, citation, summons, subpoena, investigation or other proceeding (whether civil, criminal, administrative, regulatory, investigative or informal) before any Governmental Authority, court or arbitrator pending or, to the Knowledge of Purchaser, threatened, against Purchaser or Purchaser GP, that, in each case, challenges or seeks to prevent, enjoin, alter, delay, make illegal or otherwise interfere with the consummation of any of the transactions contemplated by any of the Transaction Documents.

Purchaser has not taken any action that would entitle any Person to any commission or broker’s fee in connection with the transactions contemplated by this Agreement.

The Parties covenant and agree as follows, in each case during the Term:

(a)Seller and Purchaser shall execute and deliver to Licensee the Licensee Consent and Direction on the date hereof.

(b)If Purchaser receives any payment on account of the Retained Accounts or any other Excluded Asset, Purchaser shall:

(i)hold such payment in trust for the benefit of Seller;

(ii)have no right, title or interest whatsoever in such payment; and

(iii)promptly, and in any event no later than ten (10) Business Days following the receipt by Purchaser of such payment, remit the full amount thereof that comprises the Retained Accounts or such other Excluded Asset to

the Seller Account by wire transfer of immediately available funds, without set-off, withholding or deduction of any kind.

(c)If Seller receives any payment on account of the Purchased Accounts (other than the Purchase Price), Seller shall:

(i)hold such payment in trust for the benefit of Purchaser;

(ii)have no right, title or interest whatsoever in such payment; and

(iii)promptly, and in any event no later than ten (10) Business Days following the receipt by Seller of such payment, remit the full amount thereof that comprises the Purchased Accounts to the Escrow Account by wire transfer of immediately available funds, without set-off, withholding or deduction of any kind, following which Seller shall, jointly with Purchaser in accordance with the Escrow Agreement, direct the Escrow Agent to immediately distribute such funds to Purchaser in accordance with the Escrow Agreement.

(d)Without limiting the generality of Section 2.3, if, notwithstanding Section 5.8 of the License Agreement, Licensee sets off or credits against any Accounts that are Purchased Accounts (i) any amount owing from Seller to the Licensee in respect of any right of Licensee against Seller arising from or in connection with any matter, or (ii) any amount on account of any overpayment of Royalty Payments by Licensee to Seller in respect of Net Sales of the Relevant Product in the Territory that occurred during the period prior to the Purchased Accounts Period, (the amounts referred to in clause (i) and (ii), the “Seller Obligation”), or if Licensee makes any other adjustment to the Purchased Accounts on account of any Seller Obligation, then Seller shall promptly (and in any event no later than ten (10) Business Days) following the date on which Seller becomes aware of such set-off, credit or other adjustment, notify Purchaser, in writing, thereof, remit to the Escrow Account funds in an amount equal to such set off, credit or other adjustment, without set off, withholding or deduction of any kind, and thereafter jointly with Purchaser in accordance with the Escrow Agreement direct the Escrow Agent to immediately distribute such funds to Purchaser.

(e)If, notwithstanding Section 5.8 of the License Agreement, at any time (including following the completion of any inspection or audit under Section 5.13 of the License Agreement), Licensee sets-off or credits against the Retained Accounts or any other payments that Licensee owes to Seller in connection with any matter other than the Purchased Accounts, all or a portion of any overpayment of the Purchased Accounts (any such overpayment, a “Purchased Accounts Overpayment”), or if Licensee makes any other adjustment to the Retained Accounts or any such other payments on account of any Purchased Accounts Overpayment, then Purchaser shall promptly (and in any event within ten (10) Business Days) following receipt of a written request from Seller (which request shall include reasonable supporting details) reimburse to Seller the amount of such set-off, credit or other adjustment (not to exceed the Purchased Accounts Overpayment), without set off, withholding or deduction of any kind, by payment to the Seller Account.

(f)Seller shall comply with its obligation under Section 5.7(b) of the License Agreement during the Term and shall provide to Purchaser a copy of each invoice provided to Licensee pursuant to such Section.

(a)Promptly (and in any event no later than five (5) Business Days) following the receipt by Seller from Licensee of (i) a Royalty Report or (ii) any material written notice or material written correspondence relating to, involving or affecting, (A) the Purchased Accounts (including written notice of any Royalty Reduction, written notice of any sublicense pursuant to Section 4.2 of the License Agreement, or written notice pursuant to Section 6.2(f) (Licensed

Broader Anti-CD19 Patents), Section 6.6 (Infringement of Third-Party Rights), Section 10.2 (Termination for Material Breach), Section 10.3 (Termination for Insolvency), Section 10.4 (Elective Termination) or Section 13.9 (Assignment) of the License Agreement or (B) any other material right of Purchaser under this Agreement relating to the Purchased Accounts, Seller shall furnish a copy of such Royalty Report or such notice or correspondence to Purchaser.

(b)Except for notices and correspondence required to be given or made by Seller (i) under the License Agreement or (ii) by Applicable Law, Seller shall not send any notice or correspondence to Licensee relating to, involving or affecting, the Purchased Accounts or any material right of Purchaser under this Agreement relating to the Purchased Accounts, in each case, without the prior written consent of Purchaser, unless the sending of such notice or correspondence would not reasonably be expected to adversely affect the value of the Purchased Accounts (including the timing, amount or duration thereof) or the exercise by Purchaser of its material rights under this Agreement relating to the Purchased Accounts. Seller shall, promptly (and in any event no later than five (5) Business Days) following the delivery thereof by Seller to Licensee, provide to Purchaser a copy of any material notice or material correspondence sent by Seller to Licensee relating to, involving or affecting, the Purchased Accounts or any material right of Purchaser under this Agreement relating to the Purchased Accounts.

(a)Seller and Purchaser shall consult with each other as set forth in this Section 5.3 regarding the timing, manner and conduct of any inspection or audit of the Licensee’s or any Sublicensee’s records with respect to the Accounts pursuant to Section 5.13 of the License Agreement. The Seller shall retain the exclusive right to inspect and audit, (or, in the case of any Sublicensee, to cause the Licensee to inspect and audit) at Seller’s sole cost and expense, Licensee’s or any Sublicensee’s records at any time and from time to time at its sole discretion for payments relating to periods prior to the Purchased Accounts Period, provided, however, that Seller shall consult with Purchaser prior to initiating any such inspection and audit. It being expressly understood that Seller can proceed with any audit without the approval or consent of Purchaser.

(b)Seller may, and if requested in writing by Purchaser, shall, (i) cause a nationally recognized independent certified public accountant to inspect or audit Licensee’s relevant records solely with respect to matters related to the Accounts pursuant and subject to Section 5.13 of the License Agreement, and (ii) cause Licensee to exercise its audit rights with respect to any Sublicensee and report the results of such audit to the Licensee (and the Licensee shall reports such results to Purchaser) pursuant and subject to Section 5.13(d); provided, however, that Purchaser shall not be entitled to request such an inspection or audit of the Licensee or of any Sublicensee more frequently than once in any calendar year. With respect to any such inspection or audit, Seller shall select such nationally recognized independent certified public accountant as Purchaser shall recommend for such purpose (provided that such independent certified public accountant is reasonably acceptable to Seller, Licensee and, if applicable, the relevant Sublicensee). All of the out-of-pocket costs and expenses of any such inspection or audit carried out at the request of Purchaser (including the fees and expenses of the independent certified public accountant selected for such inspection or audit) that would otherwise be borne by Seller pursuant to the License Agreement shall instead be borne by Purchaser and reimbursed to the Seller Account promptly upon written request (which request shall include reasonable details of costs and expenses for which Seller is seeking reimbursement).

(c)All of the costs and expenses of any inspection or audit initiated by Seller under Section 5.13 of the License Agreement solely with respect to matters unrelated to the Accounts (including the fees and expenses of the independent certified public accountant selected for such inspection or audit) shall be borne by Seller. Seller shall provide Purchaser at least ten (10) Business Days prior written notice before Seller initiates an inspection or audit under Section 5.13 of the License Agreement solely with respect to matters unrelated to the Accounts. If, no

later than five (5) Business Days after Purchaser receives such a notice, Purchaser reasonably requests (by written notice to Seller) that additional matters solely related to the Accounts be included in such inspection or audit, then Seller shall include such additional matters subject to the terms of Section 5.13 of the License Agreement (such inspection or audit, a “Purchaser Participated Audit”); provided that the out-of-pocket costs and expenses of a Purchaser Participated Audit that would otherwise be borne by Seller pursuant to the License Agreement shall instead be borne by Seller and Purchaser on a pro rata basis that reflects the portion of the total amounts received by each of them from Licensee pursuant to the License Agreement on account of royalty payments in respect of the calendar year that is the subject of the Purchaser Participated Audit, and Purchaser shall promptly, upon written request from Seller (which request shall include reasonable details of costs and expenses for which Seller is seeking reimbursement), reimburse Seller for Purchaser’s share of such costs and expenses.

(d)If, following the completion of any inspection or audit under Section 5.13 of the License Agreement, Licensee is required to make additional payments to Seller for underpayment of Accounts, then such payments received, after deduction and reimbursement of the Parties’ out-of-pocket costs and expenses (including the fees and expenses of the independent certified public accountant selected for such inspection or audit) borne by the Parties in connection with such inspection or audit pursuant to Section 5.3(b) or Section 5.3(c) (and that are not to be reimbursed pursuant to Section 5.3(e)), shall be allocated among, and paid to, the Parties, in proportion to their respective entitlements to the Accounts in respect of the calendar year that was the subject of the inspection or audit.

(e)If, following the completion of any inspection or audit under Section 5.13 of the License Agreement, Licensee reimburses Seller for the costs and expenses of such inspection or audit pursuant to Section 5.13 of the License Agreement, Seller shall promptly (and in any event within five (5) Business Days) following receipt by Seller of such reimbursement remit to Purchaser a pro rata amount of such reimbursement based on the portion of the costs and expenses of such inspection or audit that were paid, respectively, by Purchaser and Seller pursuant to Section 5.3(b) or Section 5.3(c).

Seller shall not:

(a)breach any of the provisions of the License Agreement if the effect of such breach would reasonably be expected to result in a Material Adverse Change, and Seller shall use reasonable best efforts (in consultation with Purchaser) to cure any such breach by Seller of the License Agreement in a timely manner;

(b)forgive, release or compromise any amount owed to or becoming owing to Seller under the License Agreement, which amount would otherwise constitute the Purchased Accounts, without prior written consent of Purchaser (in its sole discretion); and

(c)assign, amend, modify, supplement, restate, waive, cancel or terminate (or consent to any cancellation or termination of), in whole or in part, (each, a “Modification”) all or any provision of the License Agreement without the prior written consent of Purchaser (in its sole discretion) if such Modification would reasonably be expected to result in a Material Adverse Change (it being understood and agreed that a proposed Modification to the provisions of the License Agreement governing the obligation to make the Royalty Payments, the amount or calculation of the Royalty Payments or the procedures or timing for payment of the Royalty Payments shall be deemed to have such an effect).

(a)Promptly upon Seller becoming aware of a breach of or default under, or an alleged breach of or default under, the License Agreement by Licensee that, individually or in the aggregate with other alleged or actual breaches or defaults by Licensee, could reasonably be expected to result in a Material Adverse Change, Seller shall (i) promptly (but in any event within five (5) Business Days) provide written notice to Purchaser describing in reasonable detail the relevant breach or default, and (ii) proceed in consultation with Purchaser. Seller may, and if requested in writing by Purchaser, shall, take commercially reasonable actions (including selecting legal counsel reasonably satisfactory to Purchaser and commencing legal action against Licensee) to enforce compliance by Licensee with the relevant provisions of the License Agreement.

(b)Purchaser shall, promptly (and in any event within ten (10) Business Days) following receipt of a written request from Seller (which request shall include reasonable details of costs and expenses for which Seller is seeking reimbursement), reimburse Seller for all documented out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses) reasonably incurred by Seller as a result of Seller taking any action at the request of Purchaser pursuant to Section 5.5. To the extent not previously reimbursed by Purchaser, the amount of all documented out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses) reasonably incurred by Seller in connection with such enforcement shall be deducted from Proceeds of the enforcement of Licensee’s obligations under the License Agreement pursuant to this Section 5.5 and retained by Seller. Thereafter such Proceeds shall be used to reimburse Purchaser for all amounts reimbursed to Seller by Purchaser pursuant to this Section 5.5(b), and the balance of such Proceeds shall be allocated between the Parties in a manner that reflects their respective entitlements to the Accounts during the relevant period of time to which the enforcement action relates, as determined by the Parties, acting in good faith. For purposes of this Section 5.5(b), “documented” costs and expenses refer to individually identifiable costs and expenses that are evidenced by a written invoice or other supporting documentation that provides a reasonably detailed description of the matters giving rise to such costs and expenses.

(a)Promptly (and in any event within five (5) Business Days) following receipt by Seller of a written request from Licensee for consent to assign the License Agreement (in whole or in part) pursuant to Section 13.9 of the License Agreement, Seller shall provide written notice thereof to Purchaser. Seller not grant or withhold such consent without the prior written consent of Purchaser.

(b)Seller shall not assign the License Agreement (in whole or in part) without the prior written consent of Purchaser. Notwithstanding the foregoing, Purchaser’s consent shall not be required in connection with any assignment of the License Agreement by Seller that does not require Licensee’s consent pursuant to Section 13.9 of the License Agreement, provided that:

(i)the assignee shall agree in writing to be bound by the provisions of this Agreement as though it was Seller, such agreement to be in form and substance satisfactory to Purchaser;

(ii)such assignment shall not result in any deduction or withholding by Licensee of any taxes resulting from such assignee’s tax status or such assignee being a party to the License Agreement;

(iii)Seller shall provide written notice of any such assignment to Purchaser promptly (and in any event within five (5) Business Days) following the completion thereof; and

(iv)in connection with any assignment of the License Agreement by Seller to any Affiliate (as defined in the License Agreement) pursuant to the first sentence of Section 13.9 of the License Agreement, Seller shall remain liable and responsible for the performance and observance of all duties and obligations of the assignee under this Agreement,

(a “Permitted Seller Assignment”).

(a)Within five (5) Business Days of Seller becoming aware of the occurrence of any event that gives rise to a right on the part of Seller to terminate the License Agreement pursuant to Section 10.2 of the License Agreement, Seller shall provide written notice of such occurrence to Purchaser and consult with Purchaser in determining whether or not to exercise Seller’s right to terminate the License Agreement pursuant to such Section of the License Agreement. In any event, Seller shall not exercise its right to terminate the License Agreement pursuant to Section 10.2 of the License Agreement or otherwise, or agree with Licensee to terminate the License Agreement in whole or in part, except with the prior written consent of Purchaser.

(b)If, upon termination of the License Agreement, one or more Sublicensee Direct Licenses come into effect in accordance with Section 10.5(c) of the License Agreement:

(i)Seller’s rights and obligations under this Agreement in respect of the License Agreement shall, from and after the effective date of such termination of the License Agreement, apply in respect of each Sublicensee Direct License, mutatis mutandis; and

(ii)as soon as practicable following the effective date of such Sublicensee Direct License, Purchaser and Seller shall cooperate with one another to make mutually agreed amendments to this Agreement and to the Bill of Sale to give effect to clause (i) above.

Without limiting the generality of the foregoing, in such circumstances, references in this Agreement to the License Agreement shall be deemed to include each Sublicensee Direct License, and the provisions of this Agreement shall be construed accordingly.

(a)Subject to this Section 5.8, Purchaser shall keep confidential and not disclose to any Person (other than its Affiliates and its and its Affiliates’ Representatives (collectively, “Purchaser Recipients”)) and shall cause the Purchaser Recipients to keep confidential and not disclose to any Person, any Confidential Information. Purchaser shall, and shall cause the Purchaser Recipients to, use the Confidential Information solely in connection with Purchaser’s administration of the Transaction Documents (and not for any other purpose). The foregoing obligations shall continue until the later of (x) the termination of this Agreement and (y) the date of expiration of the confidentiality obligations of Seller under the License Agreement.

(b)“Confidential Information” means, collectively, all information (whether written or oral, or in electronic or other form, and whether furnished before, on or after the date of this Agreement) concerning or relating to Seller, Seller’s Affiliates, this Agreement, Licensee, the License Agreement, the Relevant Product, the Accounts and any information considered to be Confidential Information under the License Agreement that is furnished to Purchaser or its Representatives by or on behalf of Seller, including (i) this Agreement and the License Agreement, and (ii) any Royalty Reports, Modifications, assignments, notices, requests, correspondence, documents or other information furnished pursuant to this Agreement. Notwithstanding the foregoing, “Confidential Information” shall not include any information that (A) was known by Purchaser or any of its Representatives on a non-confidential basis at the time such information was disclosed to Purchaser or its Representatives in accordance herewith

or in accordance with the Confidentiality Agreement (as defined below), as evidenced by its written records or other competent evidence; (B) was or becomes generally available to the public (other than as a result of a disclosure by Purchaser or the Purchaser Recipients in violation of this Agreement); (C) became or becomes known to Purchaser or any of the Purchaser Recipients on a non-confidential basis from a source other than Seller, its Affiliates, Licensee and Seller’s, Seller’s Affiliates’, or Licensee’s Representatives (and without any breach of this Agreement or the Confidentiality Agreement by Purchaser or the Purchaser Recipients); provided that Purchaser or the relevant Purchaser Recipient was not aware that the source of such information was breaching any legal, contractual or fiduciary obligation to Seller, Seller’s Affiliates, or Licensee by making disclosure; or (D) is or has been independently developed by Purchaser or any of the Purchaser Recipients without use of or reference to the Confidential Information, as evidenced by its written records or other competent evidence.

(c)If Purchaser or any of the Purchaser Recipients is requested by a governmental or regulatory or self-regulatory authority or required by Applicable Law, regulation or legal process (including the regulations of a stock exchange or governmental or regulatory or self-regulatory authority or the order or ruling of a court, administrative agency or other government or regulatory body of competent jurisdiction) to disclose any Confidential Information, Purchaser shall promptly, to the extent permitted by Applicable Law, notify Seller in writing of such request or requirement so that Seller, Seller’s Affiliate, or Licensee may seek an appropriate protective order or other appropriate remedy (and if Seller, Seller’s Affiliate or Licensee seeks such an order or other remedy, Purchaser will provide such cooperation, at Seller’s sole expense, as Seller shall reasonably request). If no such protective order or other remedy is obtained and Purchaser or the relevant Purchaser Recipients are, in the view of their respective counsel (which may include their respective internal counsel), legally required to disclose Confidential Information, Purchaser or the applicable Purchaser Recipients, as the case may be, shall only disclose that portion of the Confidential Information that their respective counsel advises that Purchaser or the applicable Purchaser Recipients, as the case may be, are required to disclose and will exercise commercially reasonable efforts, at Seller’s sole expense, to obtain reliable assurance that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed. Notwithstanding the foregoing, notice to Seller shall not be required where disclosure is made (i) in response to a request by a governmental or regulatory authority having competent jurisdiction over Purchaser or any of the Purchaser Recipients, as the case may be, or (ii) in connection with a routine examination by a regulatory or self-regulatory examiner, where in each case of the immediately preceding clauses (i) and (ii), such request or examination does not expressly reference Seller, its Affiliates, the Royalty Payments or this Agreement.

(d)Notwithstanding anything herein to the contrary, nothing in this Section 5.8 shall be construed to restrict Purchaser from:

(i)including disclosure of the Purchase Price and the amount and nature of the Purchased Accounts in the footnotes to Purchaser’s audited annual financial statements, to the extent so required by Purchaser’s independent accountants, or including comparable disclosure in Purchaser’s unaudited quarterly financial statements; and

(ii)providing copies of the audited annual and unaudited quarterly financial statement, the Transaction Documents and any Royalty Reports, Modifications, assignments, notices, requests, correspondence, documents or other information furnished pursuant to this Agreement, to Purchaser’s existing or prospective lenders or investors, or its direct or indirect beneficial owners, as long as such lenders, investors or beneficial owners have agreed to be bound by the provisions of this Section 5.8 or are otherwise subject to obligations of confidentiality comparable to those set forth in this Agreement.

(e)Effective upon the date hereof, the Confidentiality Agreement dated June 7, 2023 (the “Confidentiality Agreement”), between Seller and Purchaser shall terminate and be of no further force or effect, and shall be superseded by the provisions of this Section 5.8.

(a)Neither Party shall make or cause to be made any filing, press release or similar public announcement or communication regarding the execution of this Agreement or the terms and conditions of this Agreement without the prior written consent of the other Party, provided that the Parties have agreed to issue a press release in the form attached hereto as Exhibit E to announce the transaction consummated under this Agreement following the Closing.

(b)Either Party may disclose this Agreement, or any of the terms and condition hereof, to the extent that such Party believes in good faith that such disclosure is required to comply with Applicable Law or any Judgment, or in connection with the enforcement of its rights hereunder through legal process.

(a)Promptly (and in any event within five (5) Business Days) following Seller becoming aware of any alleged or threatened infringement of any of the Listed Patents to the extent relating to the Relevant Product (each, a “Specified Infringement”), Seller shall provide written notice thereof to Purchaser, together with a copy of the notice provided to, or received from, Licensee pursuant to Section 6.5(a) of the License Agreement. Promptly thereafter, Seller and Purchaser shall consult with each other with a view to determining the appropriate course of action to take with respect to such Specified Infringement to the extent permitted by the License Agreement.

(b)To the extent permitted by the License Agreement, Seller may, and if requested in writing by Purchaser, shall, proceed, in consultation with Purchaser, to institute such a suit or other legal proceeding and to use commercially reasonable efforts to enforce the Listed Patents, and to exercise such rights and remedies, relating to such Specified Infringement as shall be available to Seller under Applicable Law, but, in each case, subject to the terms and conditions of the License Agreement and only to the extent the Specified Infringement would reasonably be expected to result in a Material Adverse Change on the rights of Purchaser. In connection with any such enforcement of the Listed Patents by Seller, Seller shall:

(i)employ lead counsel that is acceptable to Purchaser, acting reasonably;

(ii)keep Purchaser reasonably apprised of material developments, material filings and strategic decisions to be made from time to time, including sharing drafts of substantive filings in advance of filing deadlines if requested by Purchaser, reasonably taking the comments of Purchaser in respect of such material developments, material filings and strategic decisions into account; and

(iii)not settle or otherwise resolve any dispute relating to a Specified Infringement without the prior written consent of Purchaser.

With respect to any enforcement by Seller pursuant to this Section 5.10, nothing contained herein shall limit Purchaser from retaining separate counsel who shall be permitted, where reasonably practicable, to consult with the lead counsel for such enforcement selected pursuant to this Section.

(c)Purchaser shall, promptly (and in any event within ten (10) Business Days) following receipt of a written request from Seller (which request shall include reasonable details of costs and expenses for which Seller is seeking reimbursement), reimburse Seller for all

documented costs and expenses (including reasonable attorneys’ fees and expenses) reasonably incurred by Seller as a result of Seller’s enforcement of any of the Listed Patents for Specified Infringement at the request of Purchaser. To the extent not previously reimbursed by Purchaser, the amount of all documented costs and expenses (including reasonable attorneys’ fees and expenses) reasonably incurred by Seller in connection with such enforcement of the Listed Patents under this Section 5.10 shall be deducted from Seller’s share of the Proceeds (as specified in Section 6.5(g) of the License Agreement) of the enforcement of the Listed Patents for Specified Infringement. Thereafter Seller’s share of the Proceeds (as specified in Section 6.5(g) of the License Agreement) shall be used to reimburse Purchaser for all amounts reimbursed to Seller by Purchaser pursuant to this Section, and the balance of Seller’s share of the Proceeds shall be allocated among and paid to the Parties in proportion to their respective entitlements to the Accounts during the relevant period of time to which the enforcement action relates, as determined by the Parties, acting in good faith. For the avoidance of doubt, to the extent Seller’s enforcement of any of the Listed Patents is not for Specified Infringement at the request of Purchaser, Seller shall be responsible for all costs and expenses of enforcement, and Seller shall be entitled to the Proceeds.

(a)To the extent permitted by the License Agreement, Seller shall use commercially reasonable efforts to:

(i)prosecute and maintain the Listed Patents;

(ii)cause all required prosecution and maintenance fees and like payments with respect to the Listed Patents to be paid when due;

(iii)not disclaim or finally abandon any of the Listed Patents without filing a continuation application, or fail to take any commercially reasonable action necessary to prevent the disclaimer or abandonment of any of the Listed Patents; and

(iv)diligently defend any Listed Patents against interference or like proceedings by any other Person, and against any claims of invalidity or unenforceability, in any jurisdiction,

except, in each case of clauses (i), (ii), (iii) and (iv) with respect to any Listed Patent where the failure to prosecute, maintain or defend such Listed Patent would not reasonably be expected to result in a Material Adverse Change, where the failure to cause any such payments to be made in respect of such Listed Patent would not reasonably be expected to result in a Material Adverse Change, or where such disclaimer or abandonment of such Listed Patent would not reasonably be expected to result in a Material Adverse Change. At the reasonable written request by Purchaser from time to time, Seller shall keep Purchaser reasonably informed regarding the prosecution and maintenance of any Listed Patents and shall take into account any recommendations from Purchaser regarding any Listed Patents prosecuted by Seller.

(b)All costs and expenses (including attorneys’ fees and expenses) incurred by Seller in connection with the prosecution, maintenance and defense of the Listed Patents shall be borne by Seller (except that the costs and expenses for defense of the Listed Patents in the context of an enforcement action as described in Section 5.10 shall be allocated according to Section 5.10).

(c)In relation to any Listed Patent prosecuted by Seller, Seller, (i) shall use all reasonable efforts to cause each such Listed Patent to be opted out from the exclusive jurisdiction of the Unified Patent Court such patents (in accordance with Article 83(3) of the Council Agreement on a Unified Patent Court (no. OJ 2013 C 175/01)), and (ii) shall notify Purchaser in the event that it wishes to withdraw any such opt-out from the exclusive jurisdiction of the Unified Patent Court in respect of such patent (in accordance with Article 83(4) of

Agreement no. OJ 2013 C 175/01). In the event that Seller wishes to do (ii) above, Seller shall provide their notice in good time to Purchaser, so that Purchaser may provide any comments and/or recommendations on the matter, and Seller shall take Purchaser’s comments and/or recommendations reasonably into account, provided that in the event of any disagreement, Seller has sole control over the matter.

(a)Seller and Purchaser agree that for United States federal income tax purposes and, to the extent applicable, U.S. state, local, non-income and non-U.S. tax purposes, the transactions contemplated by this Agreement are intended to be treated as a sale. The Parties shall file tax returns consistent with the foregoing and shall not take a position inconsistent with the foregoing unless required pursuant to a “determination” that is final within the meaning of Section 1313 of the Code. If there is an inquiry by any taxing authority of Seller or Purchaser related to matters addressed in this Section 5.12, the Parties shall cooperate with each other in responding to such inquiry in a reasonable manner consistent with this Section 5.12.

(b)Purchaser agrees:

(i)to notify Seller and the Escrow Agent in writing as soon as practicable, but in any event at least ten (10) Business Days (if known at such time) prior to the next payment of any Purchased Accounts or other amount due to Purchaser hereunder, if (A) Purchaser becomes ineligible to use or deliver any Applicable Withholding Certificate or other tax form previously delivered pursuant to this Agreement, or (B) any Applicable Withholding Certificate, other tax form or information furnished in connection therewith or with this Agreement that was previously delivered pursuant to this Agreement ceases to be accurate or complete; and

(ii)to the extent it is legally eligible to do so, to provide to Seller and the Escrow Agent any additional tax forms or information relating to any Applicable Withholding Certificate (A) upon reasonable request by Seller or the Escrow Agent and (B) subject to 5.12(b)(i)(A), promptly upon any Applicable Withholding Certificate or other tax form previously delivered pursuant to this Agreement becoming obsolete.

(c)All payments to Purchaser under this Agreement shall be made without any deduction or withholding for or on account of any tax, provided that, if Seller reasonably determines in consultation with Purchaser that deduction or withholding of any tax has become required from any amount payable hereunder (but for this sentence) to Purchaser, then Seller shall be entitled to deduct (or cause to be deducted) such tax prior to remittance to Purchaser, provided, further, that Seller shall provide reasonable advance written notice to Purchaser of its intention to withhold and shall provide Purchaser a reasonable opportunity to take (with Seller’s cooperation) any measures that could reduce or eliminate the amount of such withholding. Seller shall remit (or cause to be remitted) any amount withheld or deducted pursuant to this Section 5.12 to the relevant taxing authority, and any amount so remitted shall be treated as paid hereunder to Purchaser. Seller shall use commercially reasonable efforts to give or cause to be given to Purchaser such assistance and such information concerning the reasons for deduction as may be reasonably necessary to enable Purchaser to claim appropriate exemption therefrom, or credit therefor, and, in each case, shall furnish Purchaser with proper evidence of the taxes withheld and remitted to the relevant taxing authority.

(d)All payments to Seller under this Agreement shall be made without any deduction or withholding for or on account of any tax, provided that, if Purchaser reasonably determines in consultation with Seller that deduction or withholding of any tax has become required from any amount payable hereunder (but for this sentence) to Seller, then Purchaser shall be entitled to deduct (or cause to be deducted) such tax prior to remittance to Seller, provided, further, that Purchaser shall provide reasonable advance written notice to Seller of its intention to withhold

and shall provide Seller a reasonable opportunity to take (with Purchaser’s cooperation) any measures that could reduce or eliminate the amount of such withholding. Purchaser shall remit (or cause to be remitted) any amount withheld or deducted pursuant to this Section 5.12 to the relevant taxing authority, and any amount so remitted shall be treated as paid hereunder to Seller. Purchaser shall use commercially reasonable efforts to give or cause to be given to Seller such assistance and such information concerning the reasons for deduction as may be reasonably necessary to enable Seller to claim appropriate exemption therefrom, or credit therefor, and, in each case, shall furnish Seller with proper evidence of the taxes withheld and remitted to the relevant taxing authority.

(e)Upon the written request of Purchaser from time to time, Seller shall exercise its right pursuant to Section 5.9 of the License Agreement to require that Licensee tender payments under the License Agreement from a U.S. or a German bank account during the Term.

From and after the date hereof, each Party shall, at the sole cost and expense of the requesting Party (including reimbursement of the non-requesting Party’s documented, reasonable, out-of-pocket legal fees and expenses), execute and deliver such additional documents, certificates and instruments, and perform such additional acts, as may be reasonably requested and necessary or appropriate to carry out the provisions of this Agreement and the other Transaction Documents, and to consummate the transactions contemplated by this Agreement and the other Transaction Documents.

Seller shall provide to Purchaser at least thirty (30) days written notice prior to any change to its legal name, jurisdiction of formation or entity type.

The closing of the purchase and sale of the Purchased Accounts contemplated hereby (the “Closing”) shall take place contemporaneously with the execution or delivery of the closing deliverables set forth in this Article 6, on the date hereof, via the electronic (including email of PDF-format documents) exchange of signatures and documents.

At the Closing, Seller shall deliver or cause to be delivered to Purchaser the following:

(a)the Bill of Sale executed by Seller;

(b)a certificate of an executive officer of Seller setting forth the incumbency and specimen signature of the officer or officers of Seller who have executed and delivered the Transaction Documents, and attaching a copy of the organizational documents of Seller;

(c)the Financing Statements, reasonably satisfactory to Purchaser, pursuant to Section 2.1(b);

(d)the Licensee Consent and Direction executed by Seller and Licensee; and

(e)the Escrow Agreement executed by Seller and the Escrow Agent.

At the Closing, Purchaser shall deliver or cause to be delivered to Seller the following:

(a)the Bill of Sale executed by Purchaser;

(b)the Licensee Consent and Direction executed by Purchaser;

(c)the Escrow Agreement executed by Purchaser and the Escrow Agent;

(d)an Applicable Withholding Certificate, duly executed by Purchaser; and

(e)payment of the Purchase Price in accordance with Section 2.2.

(a)Subject to the limitations set forth in this Article 7, from and after the Closing, Seller shall indemnify Purchaser against any and all losses, liabilities, expenses (including reasonable attorneys’ fees and expenses) and damages (collectively, “Losses”) incurred by Purchaser or its limited partners, general partners, directors, officers, employees or agents (each, a “Purchaser Indemnified Party”), to the extent arising or resulting from any of the following:

(i)any breach of any representation or warranty made by Seller in this Agreement;

(ii)any breach of any covenant or agreement of Seller contained in any of the Transaction Documents; and

(iii)the other Excluded Liabilities and Obligations.

(b)Subject to the limitations set forth in this Article 7, from and after the Closing, Purchaser shall indemnify Seller against any and all Losses incurred by Seller or its directors, officers, employees or agents (each, a “Seller Indemnified Party”), to the extent arising or resulting from any of the following:

(i)any breach of any representation or warranty made by Purchaser in this Agreement; and

(ii)any breach of any covenant or agreement of Purchaser contained in any of the Transaction Documents.

(a)In order for a Party (an “Indemnified Party”) to be entitled to any indemnification under this Article 7 in respect of Losses arising out of or involving a claim or demand made by any Person other than Purchaser or Seller against a Purchaser Indemnified Party or a Seller Indemnified Party, as applicable (a “Third Party Claim”), the Indemnified Party must, promptly after its receipt of notice of the commencement of such Third Party Claim, notify the Party from whom indemnification is sought under this Article 7 (the “Indemnifying Party”) in writing (including in such notice a brief description of such Third Party Claim, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not

affect the indemnification provided under this Article 7 except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party’s receipt thereof, copies of all documents (including court papers) received by the Indemnified Party relating to such Third Party Claim.

(b)The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, if it so chooses, to assume the defense thereof, at its own expense, with counsel selected by the Indemnifying Party; provided that such counsel is not reasonably objected to by the Indemnified Party. If the Indemnifying Party elects to assume the defense of any Third Party Claim and thereafter defends the Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, except that, if the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Claim, or if the Indemnifying Party ceases to defend the Third Party Claim, the Indemnified Party may hire its own separate counsel (provided that such counsel is not reasonably objected to by the Indemnifying Party) with respect to such Third Party Claim and the related action or suit, and the reasonable fees and expenses of such counsel shall be considered Losses for purposes of this Agreement. If the Indemnifying Party elects to assume the defense of any Third Party Claim, the Indemnifying Party shall permit the Indemnified Party to participate in, but not control, the defense of such Third Party Claim through counsel chosen by the Indemnified Party and, except in the circumstances described in the immediately preceding sentence, the fees and expenses of such counsel shall be borne by the Indemnified Party. The Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party in the defense of a Third Party Claim (which shall all be considered Losses for purposes of this Agreement) for any period during which the Indemnifying Party has not assumed the defense thereof (other than during the period prior to the time the Indemnified Party shall have notified the Indemnifying Party of such Third Party Claim).

(c)The Parties shall cooperate in the defense or prosecution of any Third Party Claim, with such cooperation to include (i) the retention of and the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim and (ii) the making available of employees on a mutually convenient basis for providing additional information and explanation of any material provided hereunder. If the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of such Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability (if any) in connection with such Third Party Claim and which does not impose any non-monetary penalties on the Indemnified Party and releases the Indemnified Party completely and unconditionally in connection with such Third Party Claim. Regardless of whether the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall not be entitled to be indemnified or held harmless pursuant to this Article 7 if the Indemnified Party shall settle such Third Party Claim without the prior written consent of the Indemnifying Party.

In order for an Indemnified Party to be entitled to any indemnification under this Article 7 in respect of Losses that do not arise out of or involve a Third Party Claim, the Indemnified Party must notify the Indemnifying Party promptly in writing (including in such notice a brief description of the claim for indemnification and the Loss, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not affect the indemnification provided under this Article 7 except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure.

(a)Notwithstanding anything in this Agreement to the contrary, other than with respect to any fraud, wilful misconduct or intentional misrepresentation, Seller shall not have any liability under clause (i) of Section 7.1(a):

(i)unless the aggregate liability for all Losses suffered by the Purchaser Indemnified Parties thereunder exceeds [***]% of the Purchase Price, in which case Seller shall pay the full amount of all such Losses (from the first dollar thereof) without regard to the foregoing threshold; or

(ii)[***].

(b)Notwithstanding anything in this Agreement to the contrary, other than with respect to any fraud, wilful misconduct or intentional misrepresentation, Purchaser shall not have any liability under clause (i) of Section 7.1(b):

(i)unless the aggregate liability for all Losses suffered by the Seller Indemnified Parties thereunder exceeds [***]% of the Purchase Price, in which case Purchaser shall pay the full amount of such Losses (from the first dollar thereof) without regard to the foregoing threshold; or

(ii)[***].

The representations and warranties contained in this Agreement shall survive the Closing solely for purposes of Section 7.1 and shall terminate on the date that is eighteen (18) months following the date hereof, other than the representations and warranties in Section 3.1, Section 3.2, Section 3.3 (but only with respect to clause (c)), Section 3.4, Section 3.9(b), Section 3.11(c), Section 4.1 and Section 4.2 (the “Fundamental Representations”), which shall survive the Closing solely for purposes of Section 7.1 and shall terminate at the end of the Term. No Party shall have any liability or obligation of any nature with respect to any representation or warranty after the termination thereof, unless the other Party shall have delivered a notice to such Party, pursuant to Section 7.2(a) or Section 7.3, claiming such a liability or obligation under Section 7.1, prior to the date that is eighteen (18) months following the date hereof or, in the case of Fundamental Representations, prior to the end of the Term.

(a)The Parties acknowledge and agree that, from and after the Closing, this Article 7 (including Section 7.4 and Section 7.5) shall provide the Parties’ sole and exclusive monetary remedy with respect to any matter or claim arising out of, relating to or in connection with any of the Transaction Documents or any of the transactions contemplated thereby, except that any such claim or matter based upon fraud shall not be subject to or limited by this Article 7. All indemnification payments made by Seller hereunder shall be treated by the Parties as adjustments to the Purchase Price for tax purposes unless otherwise required by Applicable Law.

(b)Each of the Parties further acknowledges and agrees that the other Party would be damaged irreparably in the event that any of the covenants and agreements set forth in this Agreement are not performed in accordance with their specific terms or are otherwise breached or violated. Accordingly, each of the Parties agrees that, without posting bond or other undertaking, the other Party shall be entitled to an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action, suit or other proceeding instituted in any court of

the United States or any state thereof having jurisdiction over the parties and the matter. Each Party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it shall not assert the defense that a remedy at law would be adequate.

(a)Notwithstanding anything to the contrary in this Agreement or any of the other Transaction Documents, in no event, other than circumstances of fraud, shall either Party be liable (including under Section 7.1) for any (a) lost profits or damages based on a multiple of earnings, cash flow, revenue or other metric of the other Party, (b) special, exemplary, punitive, multiple or consequential damages or (c) loss of use, business interruption, loss of any contract or other business opportunity or good will, in each case of clauses (a), (b) and (c), of the other Party, whether or not caused by or resulting from the actions of such Party or the breach of its covenants, agreements, representations or warranties under any of the Transaction Documents and whether in contract, tort or breach of statutory duty or otherwise, even if such Party has been advised of the possibility of such damages.

(b)For greater certainty, (i) nothing in this Section 7.7 shall have the effect of precluding the recovery of damages in respect of amounts that would otherwise have comprised the Purchased Accounts, notwithstanding that the loss of a receivable or a payment in the nature of the Purchased Accounts might otherwise be characterized as a pure economic loss, and (ii) Purchaser shall be entitled to make indemnification claims in respect of any portion of the Purchased Accounts that Purchaser was or would have been entitled to receive but did not receive timely or at all due to any indemnifiable event under this Agreement, and such portion of the Purchased Accounts shall not be deemed special, exemplary, punitive, multiple or consequential damages for any purpose of this Agreement.

Each Party shall make all payments required to be made by it pursuant to this Article 7 by wire transfer of immediately available funds to the bank account specified in writing by the other Party from time to time.

The term of this Agreement (the “Term”) will commence on the date hereof and will end on later to occur of (i) the day on which Purchaser has received the final payment of Accounts on account of the Purchased Accounts that Licensee is required to make pursuant to Section 5.6 of the License Agreement or (ii) in the circumstances of Section 5.7(b), the day on which Purchaser has received the final payment of Accounts on account of the Purchased Accounts that Sublicensees are required to make pursuant to the Sublicensee Direct Licenses.

(a)All notices, consents, waivers, requests and other communications hereunder shall be in writing, addressed to the recipient as set out below, and shall be effective (i) upon receipt when sent by an overnight courier, (ii) on the date personally delivered to an authorized officer of the Party to which sent, in all cases, with a copy emailed to the recipient at the applicable address, or (iii) on the date the email is sent if confirmation of receipt is received or the recipient otherwise acknowledges receipt.

(b)Each Party may, by notice given in accordance herewith to the other Party, designate any further or different address to which subsequent notices, consents, waivers and other communications shall be sent.

(a)The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns.

(b)Other than in connection with a Permitted Seller Assignment that complies with Section 5.6(b), Seller shall not assign any of its obligations and rights under this Agreement without the prior written consent of Purchaser, and any such purported assignment, delegation or transfer without such consent shall be void ab initio and of no effect. Seller shall not, without the prior written consent of Purchaser, hereafter sell, transfer, hypothecate, assign or in any manner convey or mortgage, pledge or grant a security interest or other encumbrance of any kind in any of its interest in the Listed Patents that could reasonably be expected (with or without the giving of notice or passage of time, or both) to result in a Material Adverse Change.

(c)Purchaser shall not assign any of its obligations and rights under this Agreement without the prior written consent of Seller, and any such purported assignment, delegation or transfer without such consent shall be void ab initio and of no effect. Notwithstanding the foregoing, Purchaser may assign any of its obligations and rights under this Agreement without Seller’s prior written consent to an Affiliate of Purchaser, and Purchaser shall provide written notice of any such assignment to Seller within five (5) Business Days following the completion thereof.

The relationship between Seller and Purchaser is solely that of seller and purchaser, and neither Seller nor Purchaser has any fiduciary or other special relationship with the other Party or any of its Affiliates. Nothing contained herein or in any other Transaction Document shall be deemed to constitute Seller and Purchaser as a partnership, an association, a joint venture or any other kind of entity or legal form. The Parties recognize and agree that each is operating as an independent contractor and not as an agent, partner or fiduciary of the other. For greater certainty, the Parties agree that this Agreement does not, and they do not intend this Agreement to, create a contractual partnership for U.S. federal, state, local or foreign income tax purposes.

Except to the extent contemplated in Section 7.1, this Agreement is for the sole benefit of Seller and Purchaser and their respective permitted successors and assigns, and nothing herein expressed or implied shall give or be construed to give to any Person, other than the Parties and such successors and assigns, any legal or equitable rights hereunder. Purchaser shall hold the benefit of the indemnities in Section 7.1(a) in trust for the Purchaser Indemnified Parties, and Seller shall hold the benefit of the indemnities in Section 7.1(b) in trust for the benefit of the Seller Indemnified Parties.

This Agreement, together with the other Transaction Documents and the Confidentiality Agreement, constitutes the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral, between the Parties with respect to the subject matter of this Agreement. No representation, inducement, promise, understanding, condition or warranty not set forth in this Agreement has been made or relied upon by either Party. All express or implied agreements, promises, assurances, arrangements, representations, warranties and understandings as to the subject matter hereof, whether oral or written, heretofore made are superseded by this Agreement.

(a)PURSUANT TO SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW, THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO THE RULES THEREOF RELATING TO CONFLICTS OF LAW, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

(b)Each of the Parties irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the state courts of the State of New York located in New York County, and the U.S. federal district courts of the Southern District of the State of New York (and any appellate court therefrom) in any action or proceeding arising out of or relating to or in connection with this Agreement, or for recognition or enforcement of any judgment, and each of the Parties hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such court. Each of the Parties agrees that a final judgment in any such action or proceeding may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Law.

(c)Each of the Parties hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to or in connection with this Agreement in any court referred to in Section 8.7(b). Each of the Parties hereby irrevocably

waives, to the fullest extent permitted by Applicable Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d)Each of the Parties irrevocably consents to service of process in the manner provided for notices in Section 8.2. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Applicable Law. Each of the Parties waives personal service of any summons, complaint or other process, which may be made by any other means permitted by New York law.

EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW WITH RESPECT TO ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

If one or more provisions of this Agreement are held to be invalid, illegal or unenforceable by a court, arbiter or Governmental Authority, in each case, of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, which shall remain in full force and effect, and the Parties shall replace such invalid, illegal or unenforceable provision with a new provision permitted by Applicable Law and having an economic effect as close as possible to the invalid, illegal or unenforceable provision. Any provision of this Agreement held invalid, illegal or unenforceable only in part or degree by a court of competent jurisdiction shall remain in full force and effect to the extent not held invalid, illegal or unenforceable.

This Agreement may be executed in any number of counterparts, each of which executed counterparts shall constitute an original, and all of which counterparts together shall constitute one and the same instrument. Copies of executed counterparts transmitted by email with PDF attachment shall be considered original executed counterparts.

Neither this Agreement nor any term or provision hereof may be amended, supplemented, restated, waived, changed or modified except with the written consent of the Parties. No failure or delay by either Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No notice to or demand on either Party in any case shall entitle it to any notice or demand in similar or other circumstances. No course of dealing between the Parties shall be effective to amend, modify, supplement or waive any provision of this Agreement.

(a)Subject to Section 8.12(b), this Agreement shall continue in full force and effect until the end of the Term, at which point this Agreement shall automatically terminate in its entirety, save for any rights, obligations or claims of either Party which have accrued prior to such termination (along with any corresponding limitations of liability in respect thereof).

(b)The following provisions shall survive any termination of this Agreement pursuant to this Section 8.12: Article 1 (solely to the extent necessary to give effect to the surviving provisions under this Section 8.12(b)), Section 5.8 (Confidentiality), and the rights, obligations or

claims of either Party accruing prior to termination under Section 8.12(a); Article 7 (Indemnification); and this Article 8 (Miscellaneous).
