(b) Seller, and to the Knowledge of Seller, Licensee and Stanford, has not committed any act, or failed to commit any required act, that would reasonably be expected to cause any Sutro Patents to expire prematurely, lapse or be declared invalid or unenforceable, or that estops the enforcement of such Sutro Patent against any third party. With respect to (i) any Sutro Patents for which the Seller controls the prosecution and maintenance in accordance with Section 9.1 of the Vaxcyte License Agreement, and, (ii) to the Knowledge of Seller, any other Sutro Patents, there are no unpaid maintenance or renewal fees or annuities payable to any third party that currently are overdue. No Sutro Patents have lapsed or been abandoned, cancelled, disclaimed or expired, and to the Knowledge of Seller, there is no fact, circumstance or event that would constitute a basis for any such lapse, abandonment, cancellation or expiration. To the Knowledge of Seller, each individual associated with the filing and prosecution of the Sutro Patents owned in whole or in part by Seller, including the named inventors of such Sutro Patents, has complied in all material respects with all applicable duties of candor and good faith in dealing with any Patent Office, including any duty to disclose to any Patent Office all information known by such inventors to be material to the patentability of each such Sutro Patents (including any relevant prior art), in each case, in those jurisdictions in the Territory where such duties exist.

The Sutro

Patents owned by Seller, and to the Knowledge of Seller the Licensed Sutro Patents, are not subject to any outstanding injunction, Judgment, order, decree, ruling, settlement or other final disposition of a Dispute.

(d) To the Knowledge of Seller, the Sutro Patents that have been issued or granted by the applicable Patent Office are valid and enforceable. Seller has not received any written claim or written legal opinion, whether preliminary in nature or qualified in any manner, which concludes that a challenge to the validity or enforceability of any of the issued Sutro Patents may succeed.

Seller has not received any written notice from Licensee or any other Person, and to the Knowledge of Seller, there is no Person who is or claims to be an inventor under any of the Sutro Patents who is not a named inventor thereof, or that any Person named as an inventor of any of the Sutro Patents is not an inventor thereof. To the Knowledge of Seller, there is no reasonable basis for such a claim with respect to any of the Sutro Patents owned by Seller.

(g) To the Knowledge of Seller, there is no pending or threatened Action that claims that the development, manufacture, use, marketing, sale, offer for sale, importation or distribution of any Royalty Product or of Supply Product does or will infringe, misappropriate or violate any patent or other intellectual property rights of any other Person. Seller has not received any written notice asserting or claiming any such infringement, misappropriation, or violation in respect of any Royalty Product or Supply Product. To the Knowledge of Seller, the development, manufacture, use, marketing, sale, offer for sale, importation or distribution of any Royalty Product by Licensee, or of Supply Product by or on behalf of Seller or Licensee, does not and will not constitute an infringement, misappropriation, or violation of any patent or other intellectual property rights of any other Person.

(h) The Sutro Technology licensed (or sublicensed or optioned, as the case may be) by Seller to Licensee under the Vaxcyte License Agreement constitute all of the patents, information and materials owned by or licensed to Seller or any of Seller’s Affiliates that cover the Vaccine Compositions, or the manufacture, use, or development thereof, in the Territory.

(i) Except as set forth on Exhibit C with respect to the Licensed Sutro Patents, Seller owns the entire right, title and interest, free and clear of any Liens, other than Permitted Liens, in, to and under the Sutro Patents. To the Knowledge of Seller, there are no facts that would preclude Seller from having clear title in, to and under such Sutro Patents. Other than the Licensed Sutro Patents, Seller has not in-licensed any patents or other intellectual property rights covering the manufacture, use, marketing, sale, offer for sale, importation or distribution of any Royalty Products.

(j) There are no compulsory licenses granted or, to the Knowledge of Seller, threatened to be granted under the Sutro Patents with respect to any Royalty Product or any other product that, if sold without a license, would constitute a Competitive Infringement of the Sutro Patents.

Seller has not received any written notice from or on behalf of Licensee expressing an intention by Licensee to grant any such compulsory license or otherwise Set-Off any amount from the Purchased Assets because of any amount owed or claimed to be owed from Seller to Licensee.

To the extent that Seller receives any material written correspondence regarding the prosecution, defense or enforcement of the Sutro Patents, Seller will provide such correspondence to Purchaser and provide Purchaser a reasonable opportunity to comment thereon; provided, however, that Seller shall have no such obligation to provide such correspondence to Purchaser if the disclosure thereof would adversely affect the maintenance by Seller (and/or Licensee or Stanford, as applicable) of any applicable attorney-client privilege (and, in such event, the Parties agree to use commercially reasonable efforts to effect such other arrangements to preserve such privilege, including negotiating to enter into a joint defense agreement that is acceptable to Seller, Purchaser, and, if applicable, Licensee and Stanford). Such comments will be considered by Seller in good faith.

(c) If Seller has the right pursuant to Section 9.2 of the Vaxcyte License Agreement, Article 14 of the Stanford License Agreement or applicable Law to institute suit or other Actions to enforce any of the Sutro Patents in respect of a Competitive Infringement or to participate in a suit instituted by another Person with respect to a Competitive Infringement, then promptly (and in any event within [*]) following Seller becoming aware of such right of Seller, Seller shall provide written notice to Purchaser thereof. Prior to instituting or participating in any such Action, Seller shall consult with Purchaser and consider in good faith any courses of action requested by Purchaser, and shall not proceed with instituting such Action if such Competitive Infringement relates to a Royalty Product unless as Mutually Agreed. If Seller elects to exercise

its right to institute or participate in any such Action, Purchaser shall reimburse Seller, promptly on demand, for an agreed upon (using good faith efforts) proportion of its reasonable out-of-pocket costs and expenses (including the fees and expenses of Seller’s counsel) incurred by Seller in consultation with Purchaser to fairly apportion such costs and expenses of such Action. If the Parties, notwithstanding their good faith efforts, are unable to agree upon a fair proportion within [*] of commencing negotiations, then Purchaser shall reimburse Seller, promptly on demand, [*] ([*]%) of such reasonable, out-of-pocket costs and expenses, as such costs and expenses are incurred, but solely to the extent such costs and expenses are not reimbursed or required to be reimbursed by Licensee or Stanford under the applicable License Agreement, which reimbursement shall be further reduced by multiplying such [*] ([*]%) by the Purchaser Applicable Percentage [*].

(d) If Seller declines to exercise its right to institute or participate in any such Action, Seller shall promptly give notice of such declination to Purchaser, and Purchaser shall have [*] to send a written notice to Seller objecting to such declination, at which ▇▇▇▇ ▇▇▇▇▇▇ and Purchaser shall promptly consult with each other regarding whether to proceed with the institution or participation in such Action; provided that, (i) if, with respect to such Action, no Licensee-owned Patent can reasonably be asserted in good faith to ▇▇▇▇▇ the subject Competitive Infringement, such that one or more Sutro Patents are the only Patents owned by Seller or Licensee that can reasonably be asserted in such Action to ▇▇▇▇▇ the subject Competitive Infringement, or (ii) if the basis of such Action is the Competitive Infringement by Licensee or its Affiliates, then in each case ((i) and (ii)) upon Purchaser’s reasonable written request after such consultation, Seller shall proceed, in consultation with Purchaser, to institute or participate in such Action and to use commercially reasonable efforts to enforce the Sutro Patent in respect of such Competitive Infringement, and to exercise such rights and remedies relating to such Competitive Infringement as shall be available to Seller under applicable Law, but, in each case, subject to the terms and conditions of the License Agreements and this Agreement. Seller may employ any counsel, so long as such counsel is reasonably acceptable to Purchaser. Purchaser shall reimburse Seller for (A) if the Competitive Infringement is in respect of a Pneumococcal Royalty Product, [*] ([*]%), and (B) [*], [*] ([*]%) (which reimbursement shall be further reduced by multiplying such [*] ([*]%) by the Purchaser Applicable Percentage) of Seller’s reasonable, out-of-pocket costs and expenses (including the fees and expenses of Seller’s counsel) incurred by Seller in connection with Seller’s actions exercised at Purchaser’s request pursuant to this ‎Section 5.9(d) within [*] of receipt of an invoice therefor, but solely to the extent such costs and expenses are not reimbursed or required to be reimbursed by Licensee or Stanford under the applicable License Agreement.

(e) Purchaser shall, to the extent permitted under the License Agreements and by Licensee and Stanford (as applicable), have the right, at its sole cost and expense, to participate in any meeting, discussion or Action relating to the infringement, violation, validity or enforceability of the Sutro Patents, including any counterclaim, settlement discussions or meetings; provided, however, that Purchaser shall have no such right to participate if the exercise thereof would adversely affect the maintenance by Seller (and/or Licensee or Stanford, as applicable) of any applicable attorney-client privilege (and, in such event, the Parties agree to use commercially reasonable efforts to effect such other arrangements to preserve such privilege, including negotiating to enter into a joint defense agreement that is acceptable to Seller, Purchaser, and, if applicable, Licensee and Stanford). Notwithstanding anything to the contrary herein, Seller shall

keep Purchaser reasonably informed of any such Action relating to the infringement, violation, validity or enforceability of the Sutro Patents.

(f) To the extent in respect of any Competitive Infringement, the Proceeds of any enforcement of any of the Sutro Patents controlled by (i) Seller pursuant to Article 14 of the Stanford License Agreement, Section 9.2(a) of the Vaxcyte License Agreement or otherwise if the Vaxcyte License Agreement has been terminated, (ii) Licensee pursuant to Section 9.2(a) or Section 9.2(b) of the Vaxcyte License Agreement or (iii) Stanford pursuant to Article 14 of the Stanford License Agreement, in each case of the immediately foregoing clauses (i) through (iii), after deduction (and reimbursement to Seller and Purchaser) of all costs and expenses (including attorneys’ fees and expenses) incurred by Seller and Purchaser in connection with such enforcement, shall be paid to (A) Purchaser to the extent such Proceeds are in respect of Royalties that were otherwise due hereunder, in each case, if and to the extent permitted under the License Agreements or (B) Purchaser, [*] ([*]%), and Seller, [*] ([*]%), for all other Proceeds. Any amounts payable to Purchaser shall be paid promptly (and in any event within [*]) to Purchaser by or on behalf of Seller.

Section 5.10 Assignment of License Agreement and Sutro Patents.

(a) Except in connection with an assignment of this Agreement by Seller in accordance with the provisions of ‎Section 10.3, Seller shall not dispose of, assign or otherwise transfer any of the License Agreements or the Sutro Patents without the prior written consent of Purchaser. For the avoidance of doubt, the Purchased Assets are being irrevocably sold and conveyed to Purchaser hereunder, and Seller therefore shall not, and has no right to, assign or otherwise transfer, or grant, incur or suffer to exist any Lien on, or purport to do any of the foregoing, with respect to the Purchased Assets.

(b) Promptly (and in any event within [*]) following receipt by Seller of a written request from Licensee for consent to assign the Vaxcyte License Agreement (in whole or in part), including pursuant to Section 15.1 of the Vaxcyte License Agreement, Seller shall provide notice thereof to Purchaser. Seller and Purchaser shall consult with each other regarding whether to grant such consent, and Seller only as Mutually Agreed grant such consent.

Section 5.11 Audits.

(a) Consultation. Following the Closing Date, Seller and Purchaser shall consult with each other regarding the timing, manner and conduct of any review or audit of Licensee’s books and records pursuant to Section 6.8 of the Vaxcyte License Agreement.

(b) Audits under Vaxcyte License Agreement. Following consultation in accordance with ‎Section 5.11(a), if requested in writing by Purchaser or such audit or inspection is Mutually Agreed, Seller shall to the extent permitted by Section 6.8 of the Vaxcyte License Agreement, provide written notice to Licensee to cause an inspection or audit to determine the correctness of any Royalty payments made under the Vaxcyte License Agreement or other royalties under the Vaxcyte License Agreement with respect to products that [*]. With respect to any audit commenced prior to the Royalty Reporting Trigger Date, all of the expenses of any inspection or audit requested by Purchaser shall be borne by Seller, including such fees and

expenses of any public accounting firm engaged by ▇▇▇▇▇▇ (and reasonably acceptable to Purchaser and Licensee) in connection with such an inspection or audit. With respect to any audit commenced on or following the Royalty Reporting Trigger Date, all of the expenses of any inspection or audit requested by Purchaser that would otherwise be borne by Seller pursuant to the Vaxcyte License Agreement, including such fees and expenses of any public accounting firm engaged by Seller (and reasonably acceptable to Purchaser and Licensee) in connection with such an inspection or audit shall be borne by Purchaser, and Purchaser shall reimburse Seller for any such fees Seller incurs with respect to such audit, unless Licensee reimburses Seller for such costs and expenses in accordance with Section 6.8 of the Vaxcyte License Agreement; provided that, in respect of any inspection or audit involving the audit of both Royalties with respect to Royalty Products and royalties under the Vaxcyte License Agreement with respect to products that are not Royalty Products, such costs and expenses shall instead be borne (a) with respect to such audit commenced prior to the Royalty Reporting Trigger Date, [*]and (b) with respect to such audit commenced on or following the Royalty Reporting Trigger Date, [*]. For the avoidance of doubt, if any audit is commenced prior to the Royalty Reporting Trigger Date and concludes on or following the Royalty Reporting Trigger Date, [*]. Seller will promptly furnish to Purchaser a true, correct and complete copy of any inspection or audit report prepared in connection with such an inspection or audit. If, following the completion of such inspection or audit, Seller is required to reimburse Licensee for overpayment of the Royalty, then Purchaser shall promptly upon request reimburse Seller, or, at Seller’s request, Licensee on behalf of Seller, for such overpaid amount that was actually paid to Purchaser, and shall promptly (and in any event within [*]) after making such payment provide documentation to Seller evidencing that such payment was made. If, following the completion of such inspection or audit, Licensee is required to pay amounts representing an underpayment of the Royalty during the applicable period of time, then Seller shall request that Licensee pay any such underpayments directly to the Purchaser Account or the Escrow Account, as applicable.

Section 5.12 Licensee Letter Agreement. Prior to the termination of this Agreement pursuant to ‎Section 9.1, Seller shall not, without Purchaser’s prior written consent, deliver any further directions to Licensee regarding the payment of the Purchased Assets.

Section 5.13 Tax Matters.

(a) For United States federal (and applicable state and local) and non-U.S. income Tax purposes, Seller and Purchaser intend that (a) this Agreement does not constitute or give rise to a partnership or other joint venture between Purchaser and its Affiliates, on the one hand, and Seller and its Affiliates, on the other hand, (b) Purchaser’s right to payment hereunder does not represent a return with respect to a debt or equity instrument in any entity, (c) the payments made hereunder to Purchaser are not treated as royalties or a payment for fees for services, and (d) the Milestone Payments as deferred contingent consideration for the Purchased Assets eligible for installment sale treatment under Section 453 of the Code and any corresponding provision of foreign, state or local law, as appropriate. The Parties shall not take any position inconsistent with the treatments set forth in this ‎Section 5.13, the Parties shall cooperate with each other in responding to such inquiry in a commercially reasonable manner consistent with this ‎Section 5.13.

(b) On or prior to the Closing Date, Purchaser shall deliver to Seller and Licensee a duly completed and valid IRS Form W-9 certifying that Purchaser is a United States person, as

such term is defined in Section 7701(a)(30) of the Code, and Purchaser shall provide an updated IRS Form W-9 to Seller and Licensee throughout the term of the Transaction Documents whenever required in order for Seller and Licensee to have on file a duly completed and valid IRS Form W-9.

(c) Seller shall notify Purchaser in writing promptly (but in no event later than [*]) following the receipt of any written notification by Licensee or by an Affiliate of Licensee that it intends to deduct or withhold Taxes from amounts payable pursuant to the Vaxcyte License Agreement or the Manufacturing Option Letter Agreement (any such deduction or withholding, “Permitted Tax Withholding”); provided that Seller has no obligation to notify Purchaser of any Permitted Tax Withholding due to Purchaser’s failure to comply with its obligations under ‎Section 5.13(b). Seller shall, upon the reasonable request of Purchaser and at Purchaser’s expense, reasonably cooperate with Purchaser and use its commercially reasonable efforts to make such filings and take such other actions as may be reasonably necessary and specified by Purchaser in order to allow an exemption from or reduction of any Permitted Tax Withholding; provided that Seller shall have no obligation under this sentence in respect of any withholding Tax resulting from Purchaser’s failure to comply with its obligations under ‎Section 5.13(b).

(d) All payments by Seller to Purchaser under the Transaction Documents shall be made without any deduction or withholding by Seller for or on account of any Tax unless as required by applicable Law. Seller acknowledges and agrees that, so long as Purchaser complies with its obligations under ‎Section 5.13(b) and ‎Section 6.3(b)(iii), Seller does not expect to deduct or withhold any Taxes from payments to Purchaser under this Agreement. If Seller subsequently determines that any applicable Law (as reasonably determined by Seller) requires the deduction or withholding of any Tax by Seller from any amount payable by Seller hereunder, then Seller shall be entitled to make such deduction or withholding from the applicable amount payable hereunder (but for this sentence) to Purchaser any income or other Tax that Seller so determined that it is required by law to withhold with respect to such amount payable to Purchaser by Seller under this Agreement prior to remittance to Purchaser. Seller shall timely remit (or cause to be timely remitted) any amount withheld or deducted pursuant to this ‎Section 5.13‎(d) to the relevant taxing authority, and any amount so remitted shall be treated as paid hereunder to Purchaser. If Seller intends to withhold or deduct Taxes from a payment to Purchaser under the Transaction Documents or directs a third party (including the Licensee) to do so, Seller shall (i) promptly notify the Purchaser in advance of undertaking such withholding or deduction and (ii) at Purchaser’s expense, take all actions including without limitation (A) providing tax certifications or making a claim for relief from such withholding or deduction under applicable law, treaty or agreement to eliminate or reduce such withholding and (B) cause to be given to Purchaser such assistance and such information, in each case, as may reasonably be necessary to enable Purchaser to claim exemption from any such withholding, reduction (or refund) thereof, or credit therefor, and in each case shall furnish Purchaser proper evidence of the Taxes withheld and remitted by Seller (or the third party) to the relevant taxing authority. Notwithstanding the above, if withholding arises as a result of an assignment by Seller pursuant to ‎Section 5.10(a) or as a result of a change in the Seller’s status as a C corporation organized under the Laws of Delaware (in each case, a “Seller Tax Action”), then Seller shall pay such additional amounts to Purchaser as necessary so that the net amount received by Purchaser, after all required deductions and withholdings (including with respect to such additional amounts), is an amount equal to the amount that it would have received had no such deductions or withholdings been made.

(e) All payments by Purchaser to Seller under the Transaction Documents shall be made without any deduction or withholding by Purchaser for or on account of any Tax unless as required by applicable Law. Purchaser acknowledges and agrees that, so long as Seller complies with its obligations under ‎Section 6.3(a)(vii), Purchaser does not expect to deduct or withhold any Taxes from payments to Seller under this Agreement. If Purchaser subsequently determines that any applicable Law (as reasonably determined by Purchaser) requires the deduction or withholding of any Tax by Purchaser from any amount payable by Purchaser hereunder, then Purchaser shall be entitled to make such deduction or withholding from the applicable amount payable hereunder (but for this sentence) to Seller any income or other Tax that Purchaser so determined that it is required by law to withhold with respect to such amount payable to Seller by Purchaser under this Agreement prior to remittance to Seller. Purchaser shall timely remit (or cause to be timely remitted) any amount withheld or deducted pursuant to this ‎Section 5.13‎(e) to the relevant taxing authority, and any amount so remitted shall be treated as paid hereunder to Seller. If Purchaser intends to withhold or deduct Taxes from a payment to Seller under the Transaction Documents or directs a third party to do so, Purchaser shall (i) promptly notify the Seller in advance of undertaking such withholding or deduction and (ii) at Seller’s expense, take all actions including without limitation (A) providing tax certifications or making a claim for relief from such withholding or deduction under applicable law, treaty or agreement to eliminate or reduce such withholding and (B) cause to be given to Seller such assistance and such information, in each case, as may reasonably be necessary to enable Seller to claim exemption from any such withholding, reduction (or refund) thereof, or credit therefor, and in each case shall furnish Seller proper evidence of the Taxes withheld and remitted by Purchaser (or the third party) to the relevant taxing authority. Notwithstanding the above, if withholding arises in respect of a payment under this Agreement by Purchaser to Seller as a result of an assignment by Purchaser or as a result of a change in Purchaser’s status as a United States person, as such term is defined in Section 7701(a)(30) of the Code, then Purchaser shall pay such additional amounts to Seller as necessary so that the net amount received by Seller, after all required deductions and withholdings (including with respect to such additional amounts), is an amount equal to the amount that it would have received had no such deductions or withholdings been made. In addition, for the avoidance of doubt, no withholding by Purchaser from the payment of the Upfront Purchase Price in respect of U.S. federal withholding taxes will be undertaken unless the Seller fails to comply with its obligations under ‎Section 6.3(a)(vii).

(f) The Parties agree not to take any position that is inconsistent with the provisions of this ‎Section 5.13 and ‎Section 10.4 on any tax return or in any audit or other judicial or administrative proceeding unless (i) the other Party has consented to the taking of such position, or (ii) the Party that contemplates taking such an inconsistent position has been advised by a nationally recognized tax counsel in writing that it is unable to conclude that the position specified in this ‎Section 5.13 is more likely than not to prevail if challenged by the tax authority having jurisdiction of the relevant Tax.

Section 5.14 Rights Transfer Events. If Seller desires to effectuate a Rights Transfer Event, then Seller shall provide reasonable (and at least [*]) prior written notice to Purchaser before entering into any definitive binding agreement to effectuate a Rights Transfer Event.

Section 5.15 Change in Name or Organization. Seller shall provide Purchaser with written notice not less than [*] prior to any change in, or amendment or alteration of, Seller’s (a) legal name, (b) form or type of organization, or (c) jurisdiction of organization.

Section 5.16 Lien Releases. On the Closing Date, Seller shall cause an UCC-3 amendment to be filed, in each case in form and substance reasonably satisfactory to Purchaser, evidencing the release of Liens in respect of the Purchased Assets.

Section 5.17 Exclusive Dealing. From the date of this Agreement until the Closing, or the earlier termination of this Agreement in accordance with ‎Article IX, Seller shall not (and Seller shall cause its Affiliates and any of its or their Affiliates’ Representatives to not) directly or indirectly: (a) solicit, initiate, encourage or otherwise facilitate the submission of any proposal or offer from any Person relating to, or enter into or consummate any transaction relating to, the acquisition of the Purchased Assets or any merger, recapitalization, share exchange, sale or exclusive license of assets or any similar transaction or any other alternative to the transactions contemplated hereby or (b) participate in any discussions or negotiations regarding, furnish any information with respect to, assist or participate in, or facilitate in any other manner, any effort or attempt by any Person to do or seek any of the foregoing. Seller shall notify Purchaser promptly if any Person makes any proposal, offer, inquiry or contact with respect to any of the foregoing (whether solicited or unsolicited) and shall provide Purchaser with oral and written notice of the terms and conditions of such proposal, offer, inquiry or contact and the identity of the Person or group of Persons making any such proposal, offer, inquiry or contact. Seller shall, and shall direct its Representatives and Affiliates to, (x) immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any other transaction proposal and (y) promptly after the date hereof request the prompt return or destruction of all confidential information previously furnished to such Person(s) for the purpose of evaluating a possible transaction proposal. It is understood that any violation of the restrictions set forth in this ‎Section 5.17 by any Person covered by ‎Section 5.17, whether or not such Person is purporting to act on behalf of Seller, shall be deemed to be a breach of ‎Section 5.17 by Seller.

Section 5.18 Preservation of the Purchased Assets. From the date of this Agreement until the Closing, or the earlier termination of this Agreement in accordance with ‎Article IX, Seller shall not:

(a) sell, transfer, license, hypothecate, abandon, assign or in any manner convey or impose any Lien on the Purchased Assets;

(e) take any action for the winding up, liquidation, dissolution or reorganization of Seller or for the appointment of a receiver, administrator or administrative receiver, trustee or similar officer of its assets or revenues;

(a) If any claim or demand made by any Person other than Purchaser or Seller against a Purchaser Indemnified Party or a Seller Indemnified Party, as applicable (such party, the “Indemnified Party” and such claim, a “Third Party Claim”) shall be brought or alleged against an Indemnified Party in respect of which indemnity is to be sought against the other Party pursuant to ‎Section 7.1 or ‎Section 7.2 (the “Indemnifying Party”), the Indemnified Party shall, promptly after receipt of notice of the commencement of such Third Party Claim, notify the Indemnifying Party in writing of the commencement thereof, enclosing a copy of all papers served, if any;

provided, that the failure to so notify such Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to any Indemnified Party under ‎Section 7.1 or ‎Section 7.2 unless, and only to the extent that, the Indemnifying Party is actually materially prejudiced by such failure.

(b) In the event that any Third Party Claim is brought against an Indemnified Party and it notifies the Indemnifying Party of the commencement thereof in accordance with this ‎Section 7.3, the Indemnifying Party will be entitled, at the Indemnifying Party’s sole cost and expense, to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnified Party under this ‎Article VII for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, that, if the Third Party Claim relates to Taxes and the Indemnifying Party has elected to assume the defense thereof, the Indemnified Party shall have the right, at the Indemnified Party’s sole cost and expense, to participate therein and such Third Party Claim will not be settled without its written consent (such consent not to be unreasonably withheld conditioned or delayed). Notwithstanding the foregoing, the Indemnifying Party may not assume the defense to a Third Party Claim (i) involving criminal liability of the Indemnified Party or any of its Affiliates or Representatives, (ii) in which equitable relief other than monetary damages is sought against the Indemnified Party or any of its Affiliates or Representatives, or (iii) if the Indemnifying Party has not notified the Indemnified Party in writing that it will be liable to indemnify the Indemnified Party with respect to all Losses relating to such Third Party Claim.

(c) In any such Third Party Claim, an Indemnified Party shall have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the sole cost and expense of such Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, (b) the Indemnifying Party has assumed the defense of such Action and has failed within a reasonable time to retain counsel reasonably satisfactory to such Indemnified Party, (c) the named parties to any such Third Party Claim (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of counsel to the Indemnified Party, or (d) the Indemnifying Party is not permitted to assume the defense of such Third Party Claim pursuant to ‎Section 7.4(b).

(d) The Indemnifying Party shall not be liable for any settlement of any Third Party Claim effected without its written consent (such consent not to be unreasonably withheld, conditioned or delayed), but, if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any Loss by reason of such settlement or judgment. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement, compromise or discharge of any pending or threatened Third Party Claim in respect of which any Indemnified Party is or could have been a party and indemnity could be sought hereunder by such Indemnified Party, unless such settlement, compromise or discharge, as the case may be, (i) includes a general and unconditional written release of such Indemnified Party and its Affiliates, in form and substance

reasonably satisfactory to the Indemnified Party, from all liability on claims that are the subject matter of such Action, (ii) does not include any statement as to an admission of fault, culpability, failure to act or violation of Law or rights of any Person by or on behalf of any Indemnified Party or its Affiliates, (iii) does not impose any continuing material obligation or restrictions on any Indemnified Party or its Affiliates, and (iv) does not involve any injunctive relief binding on the Indemnified Party or its Affiliates.

Section 7.5 Other Claims. A claim by an Indemnified Party under this ‎Article VII for any matter not involving a Third Party Claim and in respect of which such Indemnified Party would be entitled to indemnification hereunder may be made by delivering, in good faith, a written notice of demand to the Indemnifying Party, which notice shall contain (a) a description and the amount of any Losses incurred or suffered or an estimate of Losses reasonably expected to be incurred or suffered by the Indemnified Party if known, (b) a statement that the Indemnified Party is entitled to indemnification under this ‎Article VII for such Losses and a reasonable explanation of the basis therefor, and (c) a demand for payment in the amount of such Losses or an estimate of such Losses if known; provided, that the failure to so notify such Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to any Indemnified Party under ‎Section 7.1 or ‎Section 7.2 unless, and only to the extent that, the Indemnifying Party is actually materially prejudiced by such failure. For all purposes of this ‎Section 7.5, Seller shall be entitled to deliver such notice of demand to Purchaser on behalf of Seller Indemnified Parties, and Purchaser shall be entitled to deliver such notice of demand to Seller on behalf of Purchaser Indemnified Parties.

Section 7.6 Time Limitations.

(a) Seller shall have liability under ‎Section 7.1 with respect to any breach of any representation or warranty made by Seller in ‎Article III of this Agreement only if, on or prior to the date that is [*] after the Closing Date, Purchaser notifies Seller of a claim in respect of such breach, specifying the factual basis of such claim in reasonable detail (other than any breach of any representation or warranty resulting from fraud or willful misconduct on the part of Seller or with respect to any Seller Fundamental Representations, as to which a claim may be made at any time until the date that is [*] after the termination of this Agreement). Covenants or agreements to be performed after the Closing shall terminate and expire on the date that is [*] after the last date on which such covenant or agreement is to be performed (excluding covenants and agreements in which no date is specified, which shall terminate and expire on the date that is [*] after the termination of this Agreement).

(b) Purchaser shall have liability under ‎Section 7.2 with respect to any breach of any representation or warranty made by Purchaser in ‎Article IV of this Agreement only if, on or prior to the date that is [*] after the Closing Date, Seller notifies Purchaser of a claim in respect of such breach, specifying the factual basis of such claim in reasonable detail (other than any breach of any representation or warranty resulting from fraud or willful misconduct on the part of Purchaser or with respect to any Purchaser Fundamental Representations, as to which a claim may be made at any time until the date that is [*] after the termination of this Agreement). Covenants or agreements to be performed after the Closing shall terminate and expire on the date that is [*] after the last date on which such covenant or agreement is to be performed (excluding covenants and agreements in which no date is specified, which shall terminate and expire on the date that is [*] after the termination of this Agreement).

Section 7.7 Limitations on Liability.

(a) No Party shall be liable for any consequential (including lost profits), punitive, special, indirect or incidental damages under this ‎Article VII (and no claim for indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such party (including under this ‎Article VII) in or pursuant to this Agreement, except in respect of a claim for fraud, willful misconduct, intentional misrepresentation, or breaches of ‎Article VIII or to the extent a court of competent jurisdiction awards such damages to a third party in connection with a Third Party Claim. Notwithstanding the foregoing, the Parties acknowledge and agree that (x) Purchaser’s Losses, if any, for any such Action will typically include Losses for Purchased Assets payments that Purchaser was entitled to receive or would have received absent such breach, in each case in respect of its ownership of the Purchased Assets, as well as expenses incurred in connection with enforcement of this Agreement, and (y) Purchaser shall be entitled to make claims for all such missing, delayed or diminished Purchased Assets payments as Losses hereunder, and such missing, delayed or diminished Purchased Assets payments shall not be deemed consequential (including lost profits), punitive, special or indirect damages.

(b) Other than in respect of claims for fraud, willful misconduct, intentional misrepresentation, breaches of ‎Article VIII, Third Party Claims or Excluded Liabilities and Obligations, in no event shall Seller’s aggregate liability for Losses under ‎Section 7.1(a) or Purchaser’s aggregate liability for Losses under ‎Section 7.2(a) exceed (i) (A) in the case of Seller, the Purchase Price less the Purchased Assets payments actually received by Purchaser (and not required to be withheld by or returned or reimbursed to Licensee or Seller, other than pursuant to any indemnification obligation of the Purchaser hereunder) as of the date any claim for Losses is made and (B) in the case of Purchaser, the Purchase Price, and (ii) Seller shall not have any liability for Losses under ‎Section 7.1(a) and Purchaser shall not have any liability for Losses under ‎Section 7.2(a), unless and until the aggregate amount of all Losses incurred by the Indemnified Party equals or exceeds [*], in which event the Indemnifying Party shall be liable for Losses including such amount.

Section 7.8 Right of Set-Off.

(a) Subject to the procedures set forth in this ‎Section 7.8, Purchaser shall have the right, but not the obligation, to deduct from any Milestone Payment, in whole or in part, amounts owed or claimed in good faith to be owed by Seller to any Purchaser Indemnified Party pursuant to the Transaction Documents; provided that, any such deduction shall not exceed [*] ([*]%) of the Milestone Payment otherwise due to Seller, and provided further that to the extent Purchaser deducts any such amounts, it shall not be entitled to seek indemnification under this ‎Article VII with respect to such deducted amounts.

(b) If Purchaser exercises its right of Set-Off under this ‎Section 7.8, then Purchaser shall provide written notice to Seller, which notice shall contain (a) a description and the amount of any Losses incurred or suffered or an estimate of Losses reasonably expected to be incurred or suffered by the Indemnified Party if known, (b) a statement that the Indemnified Party is entitled to indemnification under this ‎Article VII for such Losses and a reasonable explanation of the basis therefor, and (c) the amount of such Losses or an estimate of such Losses if known;

provided, that the failure to so notify Seller will not relieve Seller from any liability that it may have to any Purchaser Indemnified Party under ‎Section 7.1 unless, and only to the extent that, Seller is actually materially prejudiced by such failure.

(c) If Seller notifies Purchaser within [*] following its receipt of such notice that Seller disputes Purchaser’s right of Set-Off under this ‎Section 7.8, then such dispute shall be escalated to the senior leadership of the Parties for resolution in good faith (which senior leadership shall be the Chief Executive Officer of Seller and the head of Blackstone Life Sciences), within [*] of the date on which such dispute is referred to them. If the senior leadership, notwithstanding their good faith efforts, is unable to resolve such dispute within such [*] period, then Purchaser may make such Set-Off. Any Set-Off permitted under this ‎Section 7.8 shall be subject to the limitations set forth in ‎Section 7.6 and ‎Section 7.7. For the avoidance of doubt, (i) Purchaser’s exercise of the foregoing right of Set-Off will not limit Purchaser’s right to pursue any other available remedies in law or equity, including as set forth in the ‎Article VII but subject to ‎Section 7.9 and (b) Seller retains its right to challenge such Set-Off and does not waive its right, nor shall its right be limited by this ‎Section 7.8, to pursue any remedy in law or equity.

Section 7.9 Exclusive Remedy. Except in the case of fraud or intentional breach (pursuant to which each of Purchaser and Seller accordingly preserves all remedies available with respect to any such claim or matter based thereon under applicable Law), the indemnification afforded by this ‎Article VII shall be the sole and exclusive remedy for any and all Losses awarded against or incurred or suffered by a Party in connection with the transactions contemplated by the Transaction Documents, including with respect to any breach of any representation or warranty made by a Party in any of the Transaction Documents or any certificate delivered by a Party to the other Party in writing pursuant to this Agreement or any breach of or default under any covenant or agreement by a Party pursuant to any Transaction Document. Notwithstanding the foregoing, nothing in this Agreement shall operate to limit the rights of a Party to seek equitable remedies (including specific performance or injunctive relief) or, in the case of fraud or intentional breach committed by or on behalf of the other Party, any remedies available to it under applicable Law.

Article VIII
CONFIDENTIALITY

Section 8.1 Confidentiality. Except as provided in this ‎Article VIII or otherwise agreed in writing by the parties, the Parties agree that, during the term of this Agreement and until the seventh (7th) anniversary of the date of termination of this Agreement (or such longer period as required by the Vaxcyte License Agreement solely in respect of information deemed Confidential Information thereunder), each party (the “Receiving Party”) shall keep confidential, and shall not publish or otherwise disclose to any Person (other than its Affiliates, its and its Affiliates’ Representatives, in each case, who have agreed to be bound by the provisions of this ‎Section 8.1 or are otherwise subject to reasonable restrictions of confidentiality consistent with this ‎Section 8.1) and shall not use or disclose for any purpose other than as provided for in the Transaction Documents (which includes the exercise of any rights or the performance of any obligations hereunder), any information (whether written or oral, or in electronic or other form) furnished to it by or on behalf of the other party (the “Disclosing Party”) pursuant to the Existing Confidentiality Agreement (as defined below) or this Agreement (such information, “Confidential Information” of the Disclosing Party), except for that portion of such information that:

(a) was already in the Receiving Party’s possession on a non-confidential basis prior to its disclosure to it by the Disclosing Party, as evidenced by written records (provided, if such information was disclosed to the Receiving Party on a non-confidential basis by a party that is not the Disclosing Party, such party had the right to disclose such information to the Receiving Party without any legal, contractual or fiduciary obligation to, any person with respect to such information);

(b) is or becomes generally available to the public other than as a result of an act or omission by the Receiving Party or its Affiliates in breach of this Agreement;

(c) was independently developed by the Receiving Party, as evidenced by written records, without use of or reference to the Confidential Information or in violation of the terms of this Agreement.

Section 8.2 Disclosures to Certain Affiliates. Notwithstanding anything to the contrary provided elsewhere herein, none of Purchaser’s Affiliates (including portfolio companies) or its Affiliates’ Representatives, or any actual or potential assignees, partners (including prospective and actual limited partners), financing sources or investors (and their Representatives), including, for the avoidance of doubt, Blackstone Inc., shall have any obligations with respect to Confidential Information provided to Purchaser pursuant to this Agreement to the extent that such Confidential Information is not made available to such Affiliates (including portfolio companies), Affiliates’ Representatives, or any actual or potential assignees, partners (including prospective and actual limited partners), financing sources or investors (and their Representatives). In addition, the Confidential Information may be disclosed to any of the Persons listed in the foregoing sentence solely for the purpose of assessing, monitoring, negotiating and consummating investment opportunities and the performance of this Agreement, or resolving conflicts relating to this Agreement, or determining the proper allocation of investment opportunities, only if such Person is or agrees to be bound by the confidentiality and use provisions of this ‎Article VIII, and if such disclosure is made, Purchaser shall indemnify the Seller in accordance with ‎Article VII for any breach by such individual of such confidentiality and use provisions; provided, however, that receipt of Confidential Information by such individual shall not be imputed to the individual’s broader business unit (e.g., the broader Affiliate entity).

Section 8.3 Termination of Confidentiality Agreement. Effective at the Closing, the Confidentiality Agreement, dated February 21, 2023 (the “Existing Confidentiality Agreement”), between Seller and Blackstone Life Sciences Advisors L.L.C. shall terminate and be of no further force or effect, and shall be superseded by the provisions of this ‎Article VIII.

Section 8.4 Permitted Disclosure.

(a) In the event that a Receiving Party or its Affiliates or any of its or its Affiliates’ Representatives are requested by a Governmental Authority or required by applicable Law, regulation or legal process (including the regulations of a stock exchange or Governmental 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, the Disclosing Party shall promptly, to the extent permitted by Law, notify the non-Disclosing Party in writing of such request or requirement so that the non-Disclosing Party may seek an appropriate protective order

or other appropriate remedy (and if the non-Disclosing Party seeks such an order or other remedy, the Disclosing Party will provide such cooperation, at the non-Disclosing Party’s sole expense, as the non-Disclosing Party shall reasonably request). If no such protective order or other remedy is obtained and the Disclosing Party or its Affiliates or its or its Affiliates’ Representatives are, in the view of their respective counsel (which may include their respective internal counsel), legally required to disclose Confidential Information, the Disclosing Party or its Affiliates or its or its Affiliates’ Representatives, as the case may be, shall only disclose that portion of the Confidential Information that their respective counsel advises that Purchaser or its Affiliates or its or its Affiliates’ Representatives, as the case may be, are required to disclose and will exercise commercially reasonable efforts, at the non-Disclosing Party’s sole expense, to obtain reliable assurance that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed. In any event, the Receiving Party will not oppose action by the Disclosing Party to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. Notwithstanding the foregoing, notice to the Disclosing Party shall not be required where disclosure is made (i) in response to a request by a Governmental Authority having competent jurisdiction over the Receiving Party, its Affiliates or its or its Affiliates’ Representatives, as the case may be, or (ii) in connection with a routine examination by a regulatory examiner, where in each case such request or examination does not expressly reference Disclosing Party, its Affiliates, the Royalty, the Purchased Assets or this Agreement.

(b) Either Party may disclose Confidential Information with the prior written consent of the Disclosing Party or to the extent such disclosure is reasonably necessary in the following situations:

(i) prosecuting or defending litigation;

(ii) for regulatory, tax or customs purposes;

(iii) for audit purposes, provided that each recipient of Confidential Information must be bound by customary obligations of confidentiality and non-use prior to any such disclosure;

(iv) to the extent such disclosure of this Agreement or the transactions contemplated hereby is reasonably necessary to comply with the Securities Act of 1933, as amended, with the Securities Exchange Act of 1934, as amended, or with any rule, regulation or legal process promulgated by the SEC or a stock exchange, provided that prior to the submission by the filing Party to the SEC of any filings containing Confidential Information, to the extent practicable and permitted by applicable Law, the filing Party shall provide drafts of such filings to the other Party within a reasonable period of time but in any event no less than [*] prior to the planned date of such submission, to review any redactions related thereto, and the filing Party shall consider in good faith any comments by the other Party thereto;

(v) disclosure to its actual or potential investors and co-investors, and other sources of funding, including debt financing, or potential partners, collaborators or acquirers, and their respective accountants, financial advisors and other

professional representatives, provided, that such disclosure shall be made only to the extent customarily required to consummate such investment, financing transaction partnership, collaboration or acquisition and that each recipient of Confidential Information must be bound by customary obligations of confidentiality and non-use prior to any such disclosure; or

(vi) as is necessary in connection with a permitted assignment pursuant to ‎Section 10.3.

Section 8.5 Financial Statements. Notwithstanding anything herein to the contrary, nothing in this ‎Article VIII shall be construed to restrict either Party from (a) providing copies of Royalty Reports to its independent accountants, provided such independent accountants have agreed to be bound by the provisions of ‎Section 8.1 or are bound by customary obligations of confidentiality and non-use prior to any such disclosure, or including disclosure of the Purchase Price and the amount and nature of the Purchased Assets in the footnotes to such Party’s audited annual financial statements, in each case to the extent so required by GAAP or such Party’s independent accountants, or including comparable disclosure in such Party’s unaudited quarterly financial statements, (b) providing copies of such audited annual and unaudited quarterly financial statements to such Party’s existing or prospective lenders or direct or indirect beneficial owners, as long as such lenders or beneficial owners have agreed to be bound by the provisions of this ‎Article VIII or are otherwise subject to reasonable restrictions of confidentiality, or (c) disclosing Confidential Information in connection with any assignment permitted under ‎Section 10.3, and in accordance with the requirements of this ‎Article VIII.

Section 8.6 Specific Enforcement. Each Party acknowledges and agrees that remedies at law may not be adequate to protect Seller or Purchaser against any actual or threatened breach of this ‎Article VIII by Purchaser or Seller, either of its Affiliates or its or their Affiliates’ Representatives, and that Seller and Purchaser (as applicable) shall be entitled to seek specific performance and temporary and permanent injunctive relief or other equitable relief as a remedy for any such actual or threatened breach. Such remedy shall not be deemed to be the exclusive remedy for breach of this ‎Section 8.6 but shall be in addition to all other rights and remedies available at law or equity to Seller or Purchaser (as applicable).

Section 8.7 Use of Name. Except as required by Law, neither Party shall use the name, trademark, service mark, trade name, or symbol or any adaptation thereof of the other Party (including with respect to Purchaser, any reference to “Blackstone”) or of any of its Representatives, Affiliates, partners, managers, directors, board members, members, officers, funds, employees or agents for advertising, marketing, endorsement, promotional or sales literature, publicity, public announcement or disclosure in any document employed to obtain funds or financing without the specific prior written consent of an authorized representative of the other Party or individual whose name is to be used as to each such use (which consent may be granted or withheld in such Party’s sole discretion). Notwithstanding the foregoing, each Party may use the name, logos, and other insignia of the other Party (including with respect to Purchaser, any reference to “Blackstone”) in any “tombstone” or other advertisements, in its publications, marketing or promotional materials to existing and prospective investors and otherwise on the website or in other marketing materials of such Party, as applicable, without the other Party’s prior approval.

Article IX
TERMINATION

Section 9.1 Termination of Agreement.

(a) Prior to the Closing, this Agreement may be terminated at any time prior to the Closing Date by:

(i) either Seller or Purchaser, by written notice to the other Party, if the Closing has not occurred on or before the date that is [*] from the date hereof (the “End Date”); provided that the right to terminate this Agreement pursuant to this ‎Section 9.1(a) shall not be available to any Party whose breach of any representation, warranty or covenant contained in this Agreement has been the principal cause of the failure of the Closing to be consummated by such time.

(ii) Purchaser, upon the occurrence of a Material Adverse Effect if such Material Adverse Effect is not capable of being cured or, if curable, would not reasonably be expected to be cured by the End Date.

(b) Following the Closing, this Agreement shall continue in full force and effect until the date on which Purchaser has received the last payment with respect to the Purchased Assets, at which time this Agreement shall automatically terminate.

Section 9.2 Effect of Termination.

(a) Upon the termination of this Agreement pursuant to ‎Section 9.1(a), this Agreement shall become void and of no further force and effect, except for any rights, obligations or claims of either Party that have accrued prior to termination; provided, however, that (a) the provisions of ‎Article I (Defined Terms and Rules of Construction), ‎Section 5.1 (Public Announcement), this ‎Section 9.2 (Effect of Termination) and ‎Article X (Miscellaneous) shall survive such termination and shall remain in full force and effect and (b) nothing contained in this ‎Section 9.2 shall relieve either party from liability for any breach of this Agreement that occurs prior to termination.

(b) Upon the termination of this Agreement pursuant to ‎Section 9.1(b), this Agreement shall become void and of no further force and effect, except for any rights, obligations or claims of either Party that have accrued prior to termination; provided, however, that (a) the provisions of ‎Article I (Defined Terms and Rules of Construction), ‎Section 2.3 (No Assumed Obligations), ‎Section 2.4 (Excluded Assets), ‎Section 5.1 (Public Announcement), ‎Section 5.6 (Misdirected Payments) (other than with respect to ‎Section 5.6(c)), ‎Section 5.11 (Audits) (for the period set forth in Section 6.8 of the Vaxcyte License Agreement), ‎Section 5.13 (Tax Matters), ‎Article VII (Indemnification), ‎Article VIII (Confidentiality), this ‎Section 9.2 (Effect of Termination) and ‎Article X (Miscellaneous) shall survive such termination and shall remain in full force and effect, (b) if, upon the termination of this Agreement, any Royalties or other amounts are payable by Licensee to Purchaser hereunder, this Agreement shall remain in full force and effect until any and all such payments have been made in full, and (except as provided in this ‎Section 9.2) solely for that purpose, and (c) nothing contained in this ‎Section 9.2 shall relieve either party from liability for any breach of this Agreement that occurs prior to termination.

Article X
MISCELLANEOUS

Section 10.1 Specific Performance. Each of the Parties acknowledges that the other Party will have no adequate remedy at law if it fails to perform any of its obligations under any of the Transaction Documents and may be damaged irreparably in the event any of the provisions of this Agreement is not performed in accordance with its specific terms or otherwise are breached or violated. In such event, each of the Parties agrees that the other Party shall have the right, without posting a bond or other undertaking, to seek 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 instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter in addition to any other remedy to which it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it will not assert, and irrevocably waives, the defense that a bond or other security will be required.

Section 10.2 Notices. All notices, consents, waivers and other communications hereunder shall be in writing and shall be effective (a) upon receipt when sent through the mails, registered or certified mail, return receipt requested, postage prepaid, with such receipt to be effective the date of delivery indicated on the return receipt, (b) upon receipt when sent by an overnight courier, (c) on the date personally delivered to an authorized officer of the party to which sent or (d) on the date transmitted by electronic transmission with a confirmation of receipt, in all cases, with a copy emailed to the recipient at the applicable address, addressed to the recipient as follows:

Section 10.3 Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Seller shall not be entitled to assign, delegate or otherwise transfer this Agreement or any of its interests, obligations or rights hereunder 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; provided that Seller may assign this Agreement without the consent of Purchaser (a) to an Affiliate so long as such assignment to an Affiliate shall be at no incremental cost, including Taxes, to Purchaser or (b) to any third party that acquires all or substantially all of Seller’s business to which this Agreement relates, whether by merger, sale of assets or otherwise, as long as such assignee agrees in a writing (i) to be bound by all the provisions of this Agreement as if such assignee were the “Seller” under this Agreement and (ii) that in the event withholding or deduction on payments to Purchaser arises that would not have applied if no such assignment had been made, to pay Purchaser such additional amounts as would be necessary so that the Purchaser will receive the net amount after such withholding deductions (including on the payments of any additional amounts) as Purchaser would have received had no such deductions or withholdings been made. Seller shall give notice to Purchaser of any assignment for which consent was not required by Purchaser promptly after the occurrence thereof and, in the event that Seller makes an assignment

to an Affiliate pursuant to clause (a) above, Seller shall remain liable to Purchaser for its obligations to Purchaser hereunder (and Purchaser shall be entitled to seek recovery for any breach or default of an obligation hereunder from Seller or from such Affiliate). Following the Closing, Purchaser may assign any of its obligations and rights hereunder, in whole or in part, without restriction and without consent of Seller; provided, however, that (A) Purchaser promptly notifies Seller of such assignment, (B) Purchaser remains liable to Seller for its obligations hereunder, (C) Purchaser shall not assign to any biopharmaceutical company (other than Licensee) without Seller’s prior written consent; provided that, for the avoidance of doubt, a “biopharmaceutical company” shall not include any Person whose primary business includes the purchase and sale of royalties or revenue interests, or the provision of financing in exchange for future royalties or revenue interests, derived from the development or commercialization of pharmaceutical, medical device or similar products, (D) each such assignee complies with ‎Section 5.13(b) (replacing “Purchaser” wherever it appears with such assignee and replacing “Closing Date” with the date that such assignee acquires an interest in Purchaser’s rights hereunder), and (E) if Purchaser assigns its right under this Agreement to more than one party, the Licensee shall not be required to pay the Royalty to more than one bank account. Purchaser may assign its right to receive Purchased Assets payments, in whole or in part, without restriction and without notice to or the consent of Seller. Any purported assignment in violation of this ‎Section 10.3 shall be null and void.

Section 10.4 Independent Nature of Relationship. The relationship between Seller and ▇▇▇▇▇▇▇▇▇ 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 (including for tax purposes) to constitute Seller and Purchaser as a partnership, an association, a joint venture or any other kind of entity or legal form.

Section 10.5 No Personal Liability. It is expressly understood and agreed by ▇▇▇▇▇▇ and Purchaser that:

(a) each of the representations, warranties, covenants and agreements in the Transaction Documents made on the part of Seller is made by Seller and is not intended to be nor is a personal representation, warranty, covenant or agreement of any other Person, including those Persons named in the definition of “Knowledge of Seller” and any other Representative of Seller or Seller’s Affiliates (the “Non-Warranting Parties”);

(b) other than Seller, no Person, including the Non-Warranting Parties, shall have any liability whatsoever for breach of any representation, warranty, covenant or agreement made in the Transaction Documents on the part of Seller or in respect of any claim or matter arising out of, relating to or in connection with the Transaction Documents or the transactions contemplated thereby;

(c) the provisions of this ‎Section 10.5 are intended to benefit each and every one of the Non-Warranting Parties and shall be enforceable by each and every one of them to the fullest extent permitted by Law; and

(d) the provisions of clauses ‎(a) – ‎(c) of this ‎Section 10.5 shall apply to Purchaser, mutatis mutandis.

Section 10.6 Entire Agreement. This Agreement, together with the Exhibits and Schedules hereto, the other Transaction Documents and the Confidentiality Agreement constitute a complete and exclusive statement of the terms of agreement between the parties, and supersede 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 herein (or in the Exhibits or Schedules hereto or the other Transaction Documents) has been made or relied upon by either party.

Section 10.7 Governing Law.

(a) THIS PURCHASE AND SALE 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 OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

(b) Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the non-exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any Action arising out of, 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 may be heard and determined in such New York State court or, to the extent permitted by applicable Law, in such federal court. Each of the Parties agrees that a final judgment in any such Action shall be conclusive and 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 Action arising out of or relating to this Agreement in any court referred to in ‎Section 10.7(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 in any such court.

(d) Each of the Parties irrevocably consents to service of process in the manner provided for notices in ‎Section 10.2. 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.

Section 10.8 Waiver of Jury Trial. EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO

A TRIAL BY JURY IN ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS PURCHASE AND SALE AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTY HAVE BEEN INDUCED TO ENTER INTO THIS PURCHASE AND SALE AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.8.

Section 10.9 Severability. If one or more provisions of this Agreement are held to be invalid, illegal or unenforceable by a court 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.

Section 10.10 Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each Party shall have received a counterpart hereof signed by the other Party. Any counterpart may be executed by electronic transmission, and such electronic transmission shall be deemed an original.

Section 10.11 Amendments; No Waivers. 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 waiver or approval hereunder shall, except as may otherwise be stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval hereunder shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable Law.

Section 10.12 Cumulative Remedies. The remedies herein provided are cumulative and not exclusive of any remedies provided by applicable Law.
