4.9 Diligence. The Parties acknowledge that Tocagen expects to commence registration trial(s) of the Tocagen Product in the Field […***…] (the “Pivotal Trial”) which Tocagen believes will require the use of a companion diagnostic assay. Accordingly, Siemens will use Commercially Reasonable Efforts to have available prior to the start of the Pivotal Trial Clinical Assays to support the performance of the Pivotal Trial with expected analytical performance characteristics. However, it is possible that Tocagen will be ready to initiate the Pivotal Trial earlier than expected. Accordingly, and notwithstanding the exclusivity of the license granted to Siemens pursuant to Section 6.3(a), Tocagen shall have the right to initiate the Pivotal Trial prior to availability of the Clinical Assay(s), in which event Tocagen may use a Third Party provider of laboratory testing services to perform the Existing Assays for the Pivotal Trial until such time as the Clinical Assay(s) are available. When the Clinical Assay(s) become available, Tocagen shall, as promptly as reasonably practicable (taking into account applicable regulatory requirements, patient safety, and the need to avoid any disruption of the Pivotal Trial), initiate an orderly transition of testing services for the Pivotal Trial to Siemens. For the avoidance of doubt, Tocagen’s use of a Third Party to perform the Existing Assays for the Pivotal Trial as contemplated by this Section 4.9 shall be without prejudice to Siemens’ right to receive royalties in accordance with Section 7.3.

4.10 Rights of Cross-Reference. Siemens hereby:

(a) grants to Tocagen, its Affiliates, and its licensees with respect to Tocagen Products, the right to cross-reference Siemens’ regulatory submissions and approvals pertaining to any Assay or Approved Product (the “Siemens Regulatory Filings”) for the purpose of obtaining and maintaining regulatory approvals with respect to Tocagen Products and Other Tocagen Products anywhere in the world;

(b) Tocagen will develop marketing materials for any Tocagen Product that has received Marketing Approval that include, to the extent legally permissible and commercially reasonable, information regarding the Approved LDT’s and how to submit samples and orders to Siemens for such Approved LDT’s.

5.4 Ex-US Agreement. In the event that an Assay is required to be performed in one or more jurisdiction(s) outside the Territory in connection with the Tocagen Trials or otherwise in connection with the commercialization of a Tocagen Product in the Field in such jurisdiction(s), the Parties will discuss in good faith to reach an agreement applicable to such jurisdiction(s) between Tocagen and one or more of Siemens’ Affiliates operating qualified facilities in such jurisdiction(s). If, after a period of […***…] days, an agreement has not been reached, Tocagen may at its sole discretion undertake the necessary activities itself or initiate alternative partnership(s) with one or more Third Parties in such jurisdiction(s) on such terms as Tocagen, in its sole discretion, deems appropriate.

5.5 Right of First Negotiation for Additional Indications.

(a) During the Term, if Tocagen proposes to pursue partnership or collaboration with one or more Third Parties for the development and commercialization of companion diagnostics for Tocagen Product for any human indication outside the Field (each an “Additional Indication”) in the Territory, then before entering into an agreement with any Third Party regarding such partnership or collaboration, Tocagen shall notify Siemens in writing of such intent, which notice shall identify the Additional Indication. During the […***…]-day period following Siemens’ receipt of such notice, Tocagen shall, and it hereby does, grant to Siemens an exclusive right of first negotiation to enter into such partnership or collaboration for an Additional Indication in the Territory. Siemens may exercise such right of first negotiation upon written notice to Tocagen given at any time prior to the expiration of such […***…]-day period. In the event of such exercise, the Parties shall negotiate in good faith for up to an additional […***…] days regarding the consideration and other terms pursuant to which Tocagen would enter into such partnership or collaboration with Siemens for an Additional Indication in the Territory, and such exclusive right shall automatically be extended until the end of such […***…]-day negotiation period. If Siemens fails to exercise its right of first negotiation for an Additional Indication by the expiration of the […***…]-day notice period, or if Siemens timely exercises such right for an Additional Indication but the Parties fail to enter into a definitive agreement for such Additional Indication by the end of such […***…]-day negotiation period, then, in each case, such Additional Indication shall be deemed a “Waived Indication” for purposes of this Section 5.5, and Tocagen shall be free to negotiate with Third Parties and to enter into an agreement with any such Third Party for such Waived Indication in the Territory.

(b) If, during the Term and prior to initiation of the Pivotal Trial, Tocagen determines to postpone or cancel development of companion diagnostics for Tocagen Product in the Field in the Territory in favor of the development of companion diagnostics for Tocagen Product for an Additional Indication (other than a Waived Indication) in the Territory, then Tocagen shall notify Siemens in writing of such determination, which notice shall identify the Additional Indication. During the […***…]-day period following Siemens’ receipt of such

CONFIDENTIAL

notice, Siemens shall have the right to substitute such Additional Indication for primary brain cancer for purposes of the definition of the “Field” hereunder. Siemens may exercise such right of substitution upon written notice to Tocagen given at any time prior to the expiration of such […***…]-day period, and upon such exercise the “Field” shall be deemed to mean such Additional Indication, instead of primary brain cancer.

5.6 No Commitment to Certain Activities. Notwithstanding the provisions of Section 5.2, Tocagen acknowledges that as of the date hereof Siemens has no commitment to carry out the activities contemplated by paragraphs (d), (e) and (g) of said Section 5.2. If Siemens does not commit to carry out such activities by July 1, 2012, then Tocagen shall have the right to terminate this Agreement as provided in Section 9.4(b).

(d) on a non-exclusive basis, solely to the extent necessary or useful to make, have made, use, sell, offer to sell, or distribute Approved IVD Products in the Territory.

The foregoing licenses include the right to sublicense solely to Affiliates of Siemens. Siemens shall at all times be responsible for the compliance of its Affiliates with this Agreement, and any non-compliance by any such Affiliate with this Agreement shall be deemed a breach of this Agreement by Siemens. For the avoidance of doubt, purchasers of Approved IVD Products sold by Siemens or a Siemens Affiliate in accordance with the licenses granted hereunder shall have the right under the Tocagen Licensed IP to use such Approved IVD Products for their intended purpose.

Nothing herein shall grant any rights to Siemens or its Affiliates under Tocagen Licensed IP or Tocagen Technology Joint Inventions to conduct, and Siemens covenants on behalf of itself and its Affiliates not to use any Tocagen Licensed IP or Tocagen Technology Joint Invention for the purpose of conducting, development or commercialization of (i) any in vitro diagnostic assay intended for use as a companion diagnostic with any product containing 5-FC (flucytosine), except for Tocagen Products as expressly set forth herein; or (ii) any in vitro diagnostic assay intended for use as a companion diagnostic with any Tocagen Product outside the Field, except as mutually agreed by the Parties in writing pursuant to Section 5.5(a). Notwithstanding the foregoing, except for actions that may be required to comply with Section 5.2(g), Siemens shall have no obligation to prevent healthcare providers ordering Assay results from making off-label use of such results.

6.4 Grant to Tocagen. Subject to the terms and conditions of this Agreement, Siemens hereby grants to Tocagen:

(a) a non-exclusive license, including the right to sublicense, under the Siemens Licensed IP solely to the extent necessary or useful to develop, make, have made, use, sell, have sold, offer for sale and import Tocagen Products and Other Tocagen Products.

Field. The license granted under this Section 6.4(b) shall include the right to sublicense solely in conjunction with the grant of a license under Tocagen Licensed IP or any Pharma Invention; and

(c) subject to, and effective only as set forth in, Section 6.5 hereof, a non-exclusive license under the Siemens Licensed IP solely to the extent necessary or useful to enable Tocagen, its Affiliate and/or the US Co-Exclusive Diagnostics Partner (if any) to exercise the rights granted to Tocagen under Section 6.5. The license granted under this Section 6.4(c) shall include the right to sublicense to the US Co-Exclusive Diagnostics Partner solely in conjunction with the grant of a license under Tocagen Licensed IP or any Pharma Invention.

Nothing herein shall grant any rights to Tocagen to use Siemens Licensed IP to conduct development or commercialization, or authorize a Third Party to conduct development or commercialization, of Assays, Approved Products or in vitro diagnostic products in the Territory except as provided in Sections 6.3(c), 6.5, 6.6 and 9.5.

6.5 Second Testing Site. At any time, Tocagen may, by written notice to Siemens, request that Siemens establish additional CLIA-accredited clinical laboratory testing capability in the Territory for the performance of testing using the Assays used at the Laboratory at a location other than (and reasonably distant from) the Laboratory, either at a facility operated by Siemens or its Affiliate or through subcontracting to a Third Party (in either case, a “Second Site”). If Siemens wishes to establish a Second Site and is willing to commit to having such Second Site ready to perform Assays within an additional […***…] days, Siemens shall so inform Tocagen in writing (such notice, the “Second Site Commitment”) within […***…] days after receipt of such notice from Tocagen. If Siemens so notifies Tocagen, Siemens shall establish such Second Site within such […***…]-day period and thereafter maintain the availability and operability of such Second Site (or an alternative Second Site) thereafter during the Term. If Siemens either fails to deliver the Second Site Commitment by the end of such […***…]-day period, or delivers the Second Site Commitment within such […***…]-day period but fails to have such Second Site ready to perform Assays by the end of such […***…]-day period (subject to extension by mutual written agreement of the Parties), then, in either case, effective upon expiration of the applicable period, Tocagen shall have the right to establish CLIA-accredited clinical laboratory testing capability in the Territory through subcontracting to a single Third Party, selected by Tocagen in its sole discretion (the “US Co-Exclusive Diagnostics Partner”), to offer and perform testing using the Assays necessary for development and/or commercialization of Tocagen Product, including the right to grant the US Co-Exclusive Diagnostics Partner a license under the Tocagen Licensed IP and a sublicense under the Siemens Licensed IP for such purpose.

6.6 Reservation of Rights. Each Party expressly reserves the right to use and license its own intellectual property that is licensed to the other Party under this Article 6 (i.e., the Siemens Licensed IP or Tocagen Licensed IP) for any purpose other than the purpose for which the other Party has expressly been granted an exclusive license under this Article 6. Tocagen expressly reserves: (a) for itself, its Affiliates and, subject to Section 6.5, the US Co-Exclusive Diagnostics Partner (if any), the right to use the Tocagen Licensed IP for the purpose for which Siemens has been granted a co-exclusive license under Section 6.3(c); and (b) subject to


				***Confidential Treatment Requested

Section 6.5, for itself and its Affiliates, the right to license the Tocagen Licensed IP to the US Co-Exclusive Diagnostics Partner for such purpose.

7. COMPENSATION.

7.1 Signing Payment. Siemens shall make a non-refundable, non-creditable, lump sum payment to Tocagen of Five Hundred Thousand Dollars ($500,000) (the “Signing Payment”) within […***…] days after the Effective Date.

7.2 Royalties on Approved Products.

(a) Beginning with the First Commercial Sale of an Approved Product, Siemens shall pay royalties to Tocagen at the rate of […***…] percent ([…***…]%) on Net Assay Revenue with respect to Approved LDTs and Net Sales Revenue with respect to Approved IVD Products from the date of such First Commercial Sale until the fifth anniversary of such First Commercial Sale (the “Siemens Royalty Period”); provided that, on an Approved Product-by-Approved Product basis, subject to Section 7.2(b) below:

(i) except as set forth in subparagraph (ii) of this Section 7.2(a), there shall be excluded from the calculation of Net Assay Revenue and Net Sales Revenue any amounts attributable to an Approved Product for which, at the time of sale thereof, an alternative test acceptable and marketed for use as a companion diagnostic with a Tocagen Product in accordance with the approved labeling for the Tocagen Product (an “Alternative Test”) was commercially available in the Territory from a source other than Siemens and its Affiliates (a “Source”); and

(ii) for any portion of the Siemens Royalty Period for an Approved Product during which each Source from which an Alternative Test for such Approved Product is available is commercializing such Alternative Test pursuant to a royalty-bearing license from Tocagen under Tocagen-controlled intellectual property, no exclusion from the calculation of Net Assay Revenue or Net Sales Revenue (as applicable) with respect to such Approved Product shall be made pursuant to subparagraph (i) of this Section 7.2(a), and, instead, the royalty rate applicable to such Net Assay Revenue or Net Sales Revenue with respect to such Approved Product shall be reduced to the lowest rate payable to Tocagen by any Source with respect to sales of such Alternative Test (if lower than […***…]%).

(b) Effective as of the first day upon which Siemens first excludes any amounts attributable to any Approved LDT from the calculation of Net Assay Revenues under Section 7.2(a), the license granted to Siemens under Section 6.3(c) will automatically convert to a non-exclusive license.

7.3 Royalties on Tocagen Products. Provided that Siemens completed performance of its obligations under the Trial Development Plan and Commercial Development Plan, then beginning with the First Commercial Sale of a Tocagen Product, Tocagen shall pay royalties to Siemens on Net Product Sales of Tocagen Products from the date of such First Commercial Sale until the fifth anniversary of such First Commercial Sale (the “Tocagen Royalty Term”), calculated separately for each of the five one-year periods of the Tocagen Royalty Term (each, a “Tocagen Royalty Year”) as follows: […***…]% of that portion of Net Product Sales in a Tocagen Royalty Year up to US $[…***…]. […***…] shall be due with respect to that portion of Net Product Sales in any Tocagen Royalty Year that are in excess of US $[…***…].

7.4 No Deductions. Except as specifically provided in this Agreement, it is understood and agreed that there shall be no deductions from the royalties payable under this Agreement.

7.5 Required Third Party Payments. If, after the Effective Date and during the Term, Siemens obtains a license under issued Third Party patents which Siemens reasonably determines upon the advice of patent counsel would, in the absence of such license, be infringed by performance of an Approved LDT in the Territory or sale of an Approved IVD Product in the Territory, then Siemens may offset […***…] percent ([…***…]%) of the royalties actually paid to such Third Party under such patent license with respect to sales of such Approved LDT or Approved IVD Product, as applicable, in the Territory against the royalties due Tocagen under Section 7.2 with respect to the particular Approved Product; provided that royalties payable under license agreement to which Siemens is a party as of the Effective Date shall not be deductible hereunder; and provided, further, that in no event shall the royalty payable by Siemens to Tocagen pursuant to Section 7.2 with respect to such Approved Product be reduced by more than […***…] percent ([…***…]%) in any calendar quarter as a result of any and all such offsets in the aggregate. Upon Tocagen’s request, Siemens shall deliver to Tocagen a true and complete copy of any such Third Party license agreement, provided that Siemens may redact from such copy any confidential or proprietary information that is not necessary for Tocagen to verify the calculation of royalties payable to Tocagen hereunder.

7.6 Royalties Payable Only Once. The obligation to pay royalties is imposed only once with respect to the same unit of a Product. Sales of Products between a Party and its Affiliates or permitted sublicensees, or among such Affiliates and permitted sublicensees, for resale shall not be considered in calculating Net Product Sales or Net Assay Revenue (as applicable), and only the subsequent resale of such Products to Third Parties shall be considered in the calculation of Net Product Sales or Net Assay Revenue (as applicable).

7.7 Royalty Reports and Accounting.

(a) Royalty Reports; Royalty Payments. The Party owing royalties under Section 7.2 or 7.3, as applicable (the “Paying Party”), shall deliver to the other Party (the “Payee”), within […***…] days after the end of each calendar quarter, reasonably detailed written accountings of the Paying Party’s Net Product Sales and/or Net Assay Revenue, as applicable (in each case, the “Net Amount”) during such calendar quarter. Such quarterly reports shall indicate the Net Amount (on a Product-by-Product basis),

CONFIDENTIAL

and the resulting calculation of royalties. The Parties acknowledge that if both Parties have incurred royalty obligations during a calendar quarter, then, after each party has had a reasonable opportunity to review the other party’s written report of gross sales and Net Amounts for such quarter, the Parties may mutually agree to have the Paying Party owing the greater amount of royalties during such calendar quarter remit a net payment of the difference between the two royalty amounts rather than requiring both Parties to make separate payments. Gross sales, Net Amounts and applicable royalties payable shall be expressed in United States Dollars.

(b) Audits. The Paying Party shall keep, and shall require its Affiliates and sublicensees to keep, complete and accurate records of the latest […***…] of sales on which royalties are payable. For the sole purpose of verifying royalties payable to the Payee, the Payee shall have the right no more than once during any […***…] period to retain an independent certified public accountant selected by the Payee and reasonably acceptable to the Paying Party, to review such records in the location(s) where such records are maintained by the Paying Party, its Affiliates or its sublicensees upon reasonable notice and during regular business hours and under obligations of confidence. Results of such review shall be made available promptly to both the Payee and the Paying Party. If the review reflects an underpayment of royalties to the Payee, such underpayment shall be promptly remitted to the Payee, together with interest calculated in the manner provided in Section 7.8. If the underpayment is equal to or greater than […***…] percent ([…***…]%) of the royalty amount that was due, the Paying Party shall pay all of the reasonable and documented costs of such review. If the review reflects an overpayment of royalties to the Payee, the amount of such overpayment shall be credited against future royalties owned by the Paying Party to the Payee, or, if the determination is made after the end of the period during which royalties are payable by the Paying Party, the amount of the overpayment shall be refunded to the Paying within […***…] days after the date of determination.

7.8 Late Payments. The Paying Party shall pay interest to the Payee on the aggregate amount of any payments that are not paid on or before the date such payments are due under this Agreement at a rate per annum that is equal to the thirty-day US Dollar London Interbank Offering Rate of interest, as reported by The Wall Street Journal as of the date payment is due, plus […***…] percent ([…***…]%), but not to exceed the highest rate permitted by applicable law, calculated on the number of days such payment is delinquent.

7.9 Tax Withholding. The Parties shall use all reasonable and legal efforts to reduce tax withholding on payments made to the Payee hereunder. Notwithstanding such efforts, if the Paying Party concludes that tax withholdings under the laws of any country are required with respect to payments to the Payee, the Paying Party shall withhold the required amount and pay it to the appropriate governmental authority. In such a case, the Paying Party shall promptly provide the Payee with original receipts or other evidence reasonably desirable and sufficient to allow the Payee to document such tax withholdings adequately for purposes of tax filings, including claiming foreign tax credits and similar benefits.

7.10 Right of Recoupment. In the event that a court of competent jurisdiction awards damages to a Party for breach of this Agreement by the other Party, which award (or the judgment upon which the award is based) is either not appealable or not appealed within the time permitted for appeal, and the other Party fails to satisfy such award, in whole or in part, within the time permitted for payment, such Party shall be entitled to recoup the amount of such damages award (or the unpaid portion thereof, as applicable) out of the royalties payable by such Party to the other Party pursuant to this Article 7.

8. PUBLICATION. Each Party to this Agreement recognizes that the publication of papers regarding results of development of Assays under this Agreement, including oral presentations and abstracts, may be beneficial to both Parties provided such publications are subject to reasonable controls to protect Confidential Information and to preserve patentability of inventions. Accordingly, all publications that relate to Assays developed under this Agreement shall be subject to the prior written approval of the non-publishing Party. A publishing Party shall therefore furnish the non-publishing Party with a copy of any proposed publication or presentation and allow such non-publishing Party at least […***…] days for review and comment prior to submission or presentation. Such non-publishing Party shall review any such material and give its comments to the publishing Party within […***…] days of the delivery of such material to such non-publishing Party. With respect to oral presentation materials and abstracts, the non-publishing Party shall make reasonable efforts to expedite review of such materials and abstracts, and shall return such items as soon as practicable to the publishing Party with appropriate comments, if any, but in no event later than […***…] days from the date of delivery to the non-publishing Party. The publishing Party shall comply with the non-publishing Party’s request to delete references to the non-publishing Party’s Confidential Information in any such material and agrees to delay any submission for publication or other public disclosure for a period of up to an additional […***…] days for the purpose of preparing and filing appropriate patent applications. Notwithstanding the foregoing, if Tocagen proposes a publication that includes results of development of Assays under this Agreement, as well as other data or results of development of a Tocagen Product and/or Other Tocagen Product, Tocagen will not be obligated to consider Siemens’ comments with respect to that portion of such proposed publication that does not relate to results of development of Assays under this Agreement.

9. TERM AND TERMINATION.

9.1 Term. This Agreement shall be effective as of the Effective Date and shall continue until the expiration of all payment obligations under this Agreement (the “Term”). Notwithstanding the foregoing, the Parties may elect to extend the Term of this Agreement by mutual written agreement prior to the expiration of the then current Term. Notwithstanding anything herein to the contrary, this Agreement is also subject to termination by mutual agreement of the Parties or pursuant to Sections 9.2, 9.3 and 9.4 below.

Siemens shall use Commercially Reasonable Efforts, similar to the level of effort used by Tocagen to transfer the Existing Assays to Siemens, to transfer to Tocagen or Tocagen’s designee sufficient information to enable Tocagen or its designee to perform the activities that would have been required under this Agreement to be performed by Siemens had such termination not occurred.

(b) If this Agreement is terminated by Siemens pursuant to Section 9.2(a), the licenses granted to Siemens under Sections 6.3(b), 6.3(c) and 6.3(d) shall survive such termination and shall become non-exclusive, perpetual and irrevocable, provided that Siemens shall have the right to terminate any such license at any time upon written notice to Tocagen.

(c) If this Agreement is terminated by either party pursuant to Section 4.4, by Siemens pursuant to Section 9.3 or by Tocagen pursuant to Section 9.4, for a minimum of forty-five (45) days after the later of (i) the termination date or (ii) completion of any required post-termination Laboratory Services and delivery to Tocagen or its designee of all results thereof, Siemens shall retain, and shall not destroy, any stocks of qualified reagents for the Assays that remain as of Siemens’ completion of such Laboratory Services, and, upon Tocagen’s request made at any time during such 45-day period, Siemens shall deliver such remaining stocks to Tocagen, provided that Tocagen shall have executed documentation reasonably satisfactory to Siemens acknowledging that the use of such reagents is restricted to investigational use pursuant to a Tocagen IND, and any other use permitted by, and in compliance with, applicable laws, regulatory guidelines and regulatory approvals.

9.6 Rights in Bankruptcy. All rights and licenses granted under or pursuant to Article 6 of this Agreement by either Party are, and will otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code. The Parties agree that the applicable licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the United States Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a Party (the “Bankrupt Party”) under the United States Bankruptcy Code, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in its possession, will be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless the Bankrupt Party elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under clause (i) above, following the rejection of this Agreement by or on behalf of the Bankrupt Party, upon written request therefor by the other Party.

9.7 Survival. The expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. The rights and obligations contained in the terms of this Agreement, which by their intent or meaning have validity beyond the term of this Agreement, shall survive the termination or expiration of this Agreement, which shall include, without limitation, Sections 4.2 (second sentence), 4.5, 4.6, 4.7, 4.8, 4.10, 6.1, 6.2, 6.4, 6.5, 6.6, 7.7, 7.8, 7.9, 9.3, 9.4, 9.5, 9.6, 9.7 and 11.3 and Articles 1, 8, 10, 12 and 13.

breach by Siemens of any representation, warranty, covenant or agreement made by it under this Agreement.

12.2 Indemnification of Tocagen. Siemens shall save, defend, indemnify and hold harmless Tocagen, its officers, agents, parent companies, advisors, employees, and permitted assigns (“Tocagen Indemnitees”), from and against any and all Losses to which any such Tocagen Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any independent Third Party to the extent arising from any negligent action or omission or willful misconduct of a Siemens Indemnitee or Siemens’ material breach of any representation, warranty, covenant or agreement hereunder, except to the extent that such Losses arise out of or result from the negligence or misconduct of any Tocagen Indemnitee or material breach by Tocagen of any representation, warranty, covenant or agreement made by it under this Agreement.

A Party that intends to seek indemnification under this Article 12 (such Party hereinafter referred to as the “Indemnitee”) with respect to a claim, demand, action or other proceeding brought against such Indemnitee by a Third Party (such claim hereinafter referred to as a “Third Party Claim”), shall promptly give written notice thereof to the Party from whom indemnification is sought (such other Party hereinafter referred to as the “Indemnitor”) within a reasonable period of time after the assertion of such Third Party Claim by such Third Party; provided, however, that the failure to provide written notice of such Third Party Claim within a reasonable period of time shall not relieve the Indemnitor of any of its obligations hereunder, except to the extent that the Indemnitor is materially prejudiced by such failure in its defense or settlement of such Third Party Claim.

13. GENERAL TERMS AND CONDITIONS.

13.1 Applicable Law and Jurisdiction. This Agreement is acknowledged to have been made in and shall be construed, governed, interpreted and applied in accordance with the laws of the State of California, without giving effect to its conflict of laws provisions. Any disputes under this Agreement shall be subject to the exclusive jurisdiction and venue of state courts and the Federal courts located in Los Angeles County, California, and the Parties hereby consent to the personal and exclusive jurisdiction and venue of these courts. Notwithstanding the foregoing provisions of this Section 13.1, nothing contained in this Agreement shall deny any Party the right to seek injunctive or other equitable relief from any court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm or to resolve disputes pertaining to the validity, construction, scope, enforceability or infringement of any patent. EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL FOR ALL DISPUTES HEREUNDER.

13.2 No Waiver. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party.

13.3 Assignment. Except as expressly provided herein, neither Party may assign any of its rights or delegate any of its duties pursuant to this Agreement without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed, except that such consent shall not be required for an assignment to an Affiliate or to any Third Party that assumes ownership or control of all or substantially all of the assigning Party’s business to which this Agreement relates, whether by merger, sale of stock, license or sale of assets or otherwise; provided that such assignment shall not release the assignor of its obligations and liabilities hereunder, and provided, further, that neither Party shall transfer ownership or control of its business to which this Agreement relates or any intellectual property licensed to the other Party hereunder, unless the transferee assumes in writing the obligations of the transferor hereunder.

13.4 Severability. If any provision of this Agreement is held to be invalid or unenforceable, all other provisions will continue in full force and effect, and the Parties will substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.

13.5 Force Majeure. Neither Party will be charged with any liability for delay in performance of an obligation under this Agreement (other than payment of amounts invoiced) when due to any act of God, war, riot, fire, explosion, or compliance in good faith with any governmental law, regulation or order. The Party affected will give written notice to the other Party of any material delay due to such causes and shall use all Commercially Reasonable Efforts to minimize the loss or inconvenience suffered by both Parties. Both Parties shall cooperate in good faith in order to minimize such loss and inconvenience and to reach an agreement as to how to proceed.
