(b) At the Closing, Purchaser shall deliver the Upfront Purchase Price to Seller.

1.7 Purchase Price. In consideration of the conveyances and licenses contemplated under this Agreement and the Ancillary Agreements (a) on the Closing Date, Purchaser shall pay to Seller, the amount of One Million Dollars ($1,000,000) (the “Upfront Purchase Price”), by wire transfer of U.S. dollars in immediately available funds to the account (or accounts) designated by Seller by notice to Purchaser on the Closing Date, and (b) upon the occurrence of an applicable Milestone Event, Purchaser shall pay to Seller the applicable Milestone Payments payable in accordance with Section 1.8 (collectively, the “Purchase Price”).

1.8 Contingent Consideration.

(a) Milestone Payments. Within [***] after the achievement of a milestone event listed below (each such milestone event, a “Milestone Event”), Purchaser shall notify Seller in writing that such Milestone Event has been achieved (each such notice, a “Milestone Notice”). Seller shall invoice Purchaser for the milestone payment corresponding to the applicable Milestone Event (each, a “Milestone Payment,” and, collectively, the “Milestone Payments”). Within [***] following the receipt of the applicable invoice from Seller, Purchaser shall, pay, or cause to be paid, the Milestone Payment corresponding to the applicable Milestone Event to Seller by depositing, or causing to be deposited, by wire transfer of immediately available funds to such bank account as may be designated by Seller. All payments to be made by Purchaser under this Section 1.8(a) shall be made in U.S. dollars. Each of the Milestone Payments shall be payable one time only, for the first achievement of the corresponding Milestone Event, regardless of how many times such Milestone Event is achieved with one or more of the same or different Products.

[***]=CERTAIN CONFIDENTIAL INFORMATION OMITTED

(b) Commercially Reasonable Efforts. Purchaser shall have sole decision-making authority over the development, registration and commercialization of the Product, provided, that, Purchaser shall, and shall cause its Affiliates, Licensees and Sublicensees, as applicable, to, use Commercially Reasonable Efforts to develop and commercialize any Product. The obligations of Purchaser set forth in this Section 1.8 shall terminate upon the date that no additional Milestone Payments are payable pursuant to Section 1.8(a) (the “Product Obligation End Date”).

(c) Purchaser Obligation. Seller hereby acknowledges and agrees that there is no assurance that Seller will receive any Milestone Payments and neither Purchaser nor any Affiliates of Purchaser promised any amounts to be received by Seller in respect of any Milestone Payments.

(d) Termination of Milestone Payments. Notwithstanding anything to the contrary in this Agreement, the obligations to make Milestone Payments hereunder and the obligations in Section 6.4 shall terminate upon the Tocagen Merger Closing.

1.9 Withholding. If Purchaser or its successor, transferee, or Affiliate is required to deduct and withhold from the amounts payable pursuant to this Agreement any tax and pay such withheld tax to any tax or revenue authorities, then Purchaser shall promptly notify Seller of such withholding and promptly furnish Seller with copies of any tax certificates or other documentation evidencing such withholding. Purchaser shall cooperate with Seller in claiming exemption from such withholding under any treaty or other applicable Law or claiming a refund of such withholding. Each Party shall provide to the other Party any tax forms that may be reasonably necessary in order for Purchaser not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. All such withheld amounts shall be treated for all purposes under this Agreement as having been delivered to Seller in respect of which such deduction and withholding was made.

1.10 Late Payments. Interest will be assessed on any overdue payments at an annual rate of [***]%, or at such lower maximum annual rate permitted by applicable Law. The payment of such interest will not prevent Seller from exercising any other rights it may have as a consequence of the lateness of any payment.

1.11 Allocation of Purchase Price. Seller and Purchaser agree to allocate the Purchase Price among the Purchased Assets for all purposes (including Tax and financial accounting) in accordance with Schedule 1.11. Seller and Purchaser shall file all Tax returns (including amended returns and claims for refund) and information reports in a manner consistent with such allocation.

1.12 Additional Terms Regarding Cross License and Transition Agreement. Purchaser acknowledges that Seller is also working to sell the RV Technology (as defined in the Cross License and Transition Agreement) and related assets. If the transaction for such sale closes before the Closing Date, the Parties agree to enter into a mutually agreed amendment to modify this Agreement as appropriate to reflect that the Cross License and Transition Agreement was executed between Seller and the purchaser in such sale before the Closing Date and will be assigned to Purchaser as a Transferred Contract.

(j) The execution and delivery of this Agreement and the consummation of the Transactions (alone or in combination with any other event), and the compliance with the provisions of this Agreement do not and will not conflict with, alter, or impair, any of the rights of Seller in or to any Transferred IP or the validity, enforceability, registrability, use, right to use, ownership, priority, duration, scope, or effectiveness of any Registered IP.

rights of termination, modification, acceleration, reacquisition, transfer or cancellation of, or result in the creation of a Lien on, any of the Purchased Assets. Seller is not required to obtain any Consent from any Governmental Body or Third Party at any time prior to the Closing in connection with the execution and delivery of this Agreement or the consummation by Seller of the Transactions except for those Consents listed on Schedule 2.8 and which Seller shall have received prior to the Closing.

Subject to the other provisions of this Section 7, following the Closing, Seller shall indemnify Purchaser, its Affiliates, and each of their respective officers, directors, employees, agents, successors and permitted assigns (each a “Purchaser Indemnified Party”) against, and hold them harmless from, any Damages suffered, incurred or sustained by any Purchaser Indemnified Party to the extent resulting from or arising out of:

(a) any Retained Liabilities;

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

(c) any breach or nonfulfillment by Seller of any of its covenants, obligations or agreements contained in this Agreement; and/or

(a) any Assumed Liabilities;

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

(c) any breach or nonfulfillment by Purchaser of any of its covenants, obligations or agreements contained in this Agreement.

7.3 Third-Party Claims(a) .

(a) In the event an Indemnified Party becomes aware of a Third Party claim (including any action or proceeding commenced or threatened to be commenced by any Third Party) that the Indemnified Party reasonably believes may result in an indemnification pursuant to Section 7.1 or Section 7.2 (any such claim, a “Third-Party Claim”), the Indemnified Party shall promptly (and in any event within 10 Business Days after becoming aware of such claim) notify the Indemnifying Party in writing of such Third-Party Claim (such notice, the “Claim Notice”). The Claim Notice shall be accompanied by copies of

any relevant and material documentation submitted by the Third Party making such Third-Party Claim and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third-Party Claim and the amount of the claimed Damages; provided, however, that no delay or failure on the part of the Indemnified Party in delivering a Claim Notice shall relieve the Indemnifying Party from any liability hereunder except and only to the extent the Indemnifying Party shall have been actually and materially prejudiced as a result of such delay or failure.

(b) Within 20 Business Days after receipt of any Claim Notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of the Third-Party Claim referred to therein at the Indemnifying Party’s sole cost and expense with counsel reasonably satisfactory to the Indemnified Party. Notwithstanding anything to the contrary contained herein, the Indemnifying Party shall not be entitled to assume or control the investigation, defense or prosecution of such Third-Party Claim if (i) a material portion of the Damages associated with such Third-Party Claim are not reasonably expected to be indemnifiable hereunder (including in the event the amount in dispute is reasonably likely to exceed the maximum amount for which the Indemnifying Party can then be liable pursuant to this Section 7); (ii) at the time of assumption or thereafter, the Indemnifying Party fails to conduct the investigation, defense or prosecution actively and diligently; or (iii) such Third-Party Claim seeks non-monetary, equitable or injunctive relief against the Indemnified Party or alleges any violation of criminal Law.

(c) The Party not controlling the defense of such Third-Party Claim (the “Non-Controlling Party”) may participate therein at its own expense; provided, however, that if the Indemnifying Party assumes control of the defense of such Third-Party Claim and the Indemnifying Party and the Indemnified Party have materially conflicting interests or different defenses available with respect to such Third-Party Claim which cause the Indemnified Party to hire their own separate counsel with respect to such proceeding, and the fees and expenses of such separate counsel to the Indemnified Party shall be at the Indemnified Party’s own cost and shall not be considered “Damages” for purposes of this Agreement. The Party controlling the defense of such Third-Party Claim (the “Controlling Party”) shall keep the Non-Controlling Party advised of the status of such Third-Party Claim and the defense thereof and shall consider in good faith recommendations made by the Non-Controlling Party with respect thereto. The Non-Controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third-Party Claim (including copies of any summons, complaint or other pleading which may have been served on such Party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third-Party Claim.

(d) The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Indemnified Party; provided, however, that the consent of the Indemnified Party shall not be required with respect to any such settlement or judgment if (i) such settlement or judgment (A) involves no admission of wrongdoing by the Indemnified Party, and (B) the sole relief provided is monetary Damages, and (ii) the Indemnifying Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party and its Affiliates, directors, officers, employees and representatives from further liability. Whether or not the Indemnifying Party shall have assumed the defense of a Third-Party Claim, the Indemnified Party shall not admit liability with respect of, or agree to any settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed; provided, however, that the consent of the Indemnifying Party shall not be required with respect to any such settlement or judgment if the Indemnified Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and that no Indemnified Party is entitled to indemnification under this Agreement in respect of such settlement or

judgment. Furthermore, a Party’s consent to any settlement of a Third-Party Claim shall not be used as evidence of the truth of the allegations in any Third-Party Claim or the merits of such Third-Party Claim and the existence of any Third-Party Claim shall not create a presumption of any breach by a Party to this Agreement of any of its representations, warranties or covenants set forth in this Agreement.

7.4 Indemnification Mechanics.

(a) In order to seek indemnification under this Section 7 for a claim which does not involve a Third-Party Claim, the Indemnified Party shall with reasonable promptness deliver a written notice (an “Indemnification Demand”) to the Indemnifying Party which contains (i) a description and the amount of any Damages incurred or reasonably expected to be incurred by the Indemnified Party (to the extent then known) and (ii) a statement that the Indemnified Party is entitled to indemnification under Section 7.1 or Section 7.2 for such Damages and a reasonable explanation of the basis therefor (to the extent then known).

(b) Upon request, the Indemnified Party shall furnish the Indemnifying Party with any information to the extent that such information is reasonably necessary in order to evaluate the Indemnification Demand. If the Indemnifying Party in good faith objects to any claim made by the Indemnified Party in the Indemnification Demand, then the Indemnifying Party shall deliver a written notice (an “Indemnification Dispute Notice”) to the Indemnified Party within 30 calendar days following receipt by the Indemnifying Party of an Indemnification Demand from such Indemnified Party. The Indemnification Dispute Notice shall set forth in reasonable detail the principal basis for the dispute of any claim made by the Indemnified Party in the Indemnification Demand. If the Indemnifying Party fails to deliver an Indemnification Dispute Notice prior to the expiration of such 30-calendar day period, then the indemnity claim set forth in the Indemnification Demand shall be conclusively determined in the Indemnified Party’s favor for purposes of this Section 7, and the Indemnified Party shall be indemnified for the amount of the Damages stated in such Indemnification Demand (or, in the case of any notice in which the Damages (or any portion thereof) are estimated, the amount of such Damages (or such portion thereof) as finally determined) on demand or, in the case of any notice in which the Damages (or any portion thereof) are estimated, on such later date when the amount of such Damages (or such portion thereof) becomes finally determined, in either case, subject to the limitations of this Section 7.

(c) If the Indemnifying Party delivers an Indemnification Dispute Notice, then the Indemnified Party and the Indemnifying Party shall attempt in good faith to resolve any such objections raised by the Indemnifying Party in such Indemnification Dispute Notice. If the Indemnified Party and the Indemnifying Party agree to a resolution of such objection, then a memorandum setting forth the matters conclusively determined by the Indemnified Party and the Indemnifying Party shall be prepared and signed by both Parties, and shall be binding and conclusive upon the Parties hereto.

(d) If no such resolution can be reached during the 30-day period following the Indemnified Party’s receipt of a given Indemnification Dispute Notice, then upon the expiration of such 30-day period (or such longer period as may be mutually agreed), the Indemnified Parties shall be entitled to pursue all remedies available to them under this Agreement or otherwise at law or in equity with respect to such claims (in each case subject to the terms and limitations set forth in this Agreement).

7.5 Limitations.

(a) Other than as set forth in this Section 7.5, in no event shall Seller’s aggregate liability to the Purchaser Indemnified Parties for indemnification claims pursuant to this Section 7 exceed the Upfront Purchase Price.

(b) Seller’s aggregate liability to the Purchaser Indemnified Parties for indemnification claims pursuant to this Section 7 arising out of Section 7.1(b) with respect to the Seller Fundamental Representations or arising out of Section 7.1(d) shall not exceed Five Million Dollars ($5,000,000); provided, however, that the sole method of payment of any amounts above the amount of the Upfront Purchase Price shall be as a set off against any future Milestone Payment to be made to Seller.

(c) The limitation in this Section 7.5 shall not apply to Seller’s indemnification obligations arising out of Section 7.1(a) or Seller’s Fraud.

(d) The Parties acknowledge that there shall not be any duplicative recovery for any Damages arising from the same facts and circumstances. To the maximum extent permitted under applicable law, the indemnification provided hereunder shall be the sole and exclusive remedy with respect to Damages of an Indemnified Party.

7.6 Right to Satisfy Indemnification Claims by Reducing Milestone Payments. Purchaser is expressly authorized, but shall not be obligated, to set off up to one hundred percent (100%) of any Damages for which it is entitled to indemnification hereunder (subject to the limitations and requirements set forth in Section 7.5), following final resolution of the claims set forth in any Indemnification Demand pursuant to Section 7.4 or otherwise pursuant to a final non-appealable order or judgment by a court of competent jurisdiction, against any Milestone Payment to be made to Seller.

7.7 Survival and Expiration of Representations, Warranties, Covenants and Agreements, and Indemnification Provision.

(a) The representations and warranties of Seller contained in this Agreement or any certificate or instrument delivered pursuant to this Agreement shall survive the Closing and remain in full force and effect until the earlier of (i) the Tocagen Merger Closing, and (ii) the one (1) year anniversary of the Closing Date, at which time they shall terminate; provided, however, that the Seller Fundamental Representations shall survive the Closing until the earlier of (A) the Tocagen Merger Closing, and (B) expiration of the applicable statute of limitations.

(b) The representations and warranties of Purchaser contained in this Agreement or any certificate or instrument delivered pursuant to this Agreement shall survive the Closing and remain in full force and effect until the earlier of (i) the Tocagen Merger Closing, and (ii) the one (1) year anniversary of the Closing Date, at which time they shall terminate; provided, however, that the Purchaser Fundamental Representations shall survive the Closing until the earlier of (A) the Tocagen Merger Closing, and (B) expiration of the applicable statute of limitations.

(c) With respect to each covenant or agreement contained in this Agreement by Seller or Purchaser, such covenant or agreement shall survive until the last date on which such covenant or agreement is to be performed or, if no such date is specified, until expiration of the applicable statute of limitations.

(d) The Parties’ indemnification obligations herein shall terminate upon the earlier of (i) the Tocagen Merger Closing, and (ii) the one (1) year anniversary of the Closing Date, except as they relate to a Claim Notice or Indemnification Demand delivered prior to termination of such indemnification obligations; provided, however, that (1) Seller’s indemnification obligations with respect to Section 7.1(a) and the Seller Fundamental Representations shall terminate upon the earlier of (A) the Tocagen Merger Closing, and (B) expiration of the applicable statute of limitations; and (2) Purchaser’s indemnification obligations with respect to Section 7.2(a) and the Purchaser Fundamental Representations shall terminate upon the earlier of (i) the Tocagen Merger Closing, and (ii) expiration of the applicable statute of limitations.

7.8 Tax Treatment of Payments. The Parties agree to treat any payments made pursuant to this Section 7 as adjustments to the Purchase Price for all Tax purposes to the maximum extent permitted by applicable Law.

SECTION 8. CONFIDENTIALITY.

8.1 Confidential Information. Except as expressly provided herein, the Parties agree that the receiving Party shall not publish or otherwise disclose and shall not use for any purpose any information furnished to it by the other Party hereto pursuant to this Agreement that is of the type generally understood to be confidential or proprietary within the pharmaceutical industry (collectively, “Confidential Information”). Notwithstanding the foregoing, Confidential Information shall not include information that, in each case as demonstrated by written documentation:

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

(d) was disclosed to the receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the disclosing Party not to disclose such information to others.

From and after the Closing Date, the Purchased Assets shall be considered the Confidential Information of Purchaser, and Purchaser shall be considered the Party disclosing such Confidential Information under this Section 8.1, without exception of subsection (a) above.

8.2 Permitted Use and Disclosures. Notwithstanding Section 8.1 above, each Party hereto may use or disclose Confidential Information of the other Party to the extent such use or disclosure is reasonably necessary (a) in the exercise of the rights granted to it hereunder (including, without limitation, disclosure to contract manufacturing organizations, contract research organizations, testing labs and other service providers), or (b) in prosecuting or defending litigation, complying with Applicable Laws or otherwise submitting information to tax or other Governmental Bodies; provided that prior to any such disclosure of Confidential Information to a Third Party, such Third Party will be bound by confidentiality obligations at least as protective of the Confidential Information as the provisions under this Section 8.2. If a Party is required by law to make any such disclosure, other than pursuant to a confidentiality agreement, it will give reasonable advance notice to the other Party of such disclosure and, save to the extent inappropriate in the case of Patent applications or the like, will use its reasonable efforts to secure confidential treatment of such information in consultation with the other Party prior to its disclosure (whether through protective orders or otherwise) and disclose only the minimum necessary to comply with such law; provided that such Confidential Information disclosed accordingly shall only lose its confidentiality protection for purposes of such legal disclosure.

8.3 Nondisclosure of Terms. Subject to Section 8.1, each Party agrees not to disclose the terms of this Agreement to any Third Party without the prior written consent of the other Party hereto, which consent shall not be unreasonably withheld, except to such Party’s attorneys, advisors and others on a need to know basis in each case under consistent with customary practice under circumstances that protect the confidentiality thereof, or to the extent required by law. If a Party is required by law to make any such disclosure, other than pursuant to a confidentiality agreement, it will give reasonable advance notice to the other Party of such disclosure and, save to the extent inappropriate in the case of Patent applications or the like, will use its reasonable efforts to secure confidential treatment of such information in consultation with the other Party prior to its disclosure (whether through protective orders or otherwise) and disclose only the minimum necessary to comply with such law; provided that such Confidential Information disclosed accordingly shall only lose its confidentiality protection for purposes of such legal disclosure.

11.9 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

11.10 Specific Performance.
