If a Party appoints a distributor to sell an authorized Generic Product

of a Licensed Product or Tevard Product, then only the consideration actually paid to such Party or its Affiliate by such distributor shall be included in the calculation of Net Sales.

In the event that any Licensed Product is sold in combination with one or more products which are themselves not Licensed Products under this Agreement for a single price, the Net Sales for such Licensed Product shall be calculated by multiplying the sales price of such combination sale by the fraction A/(A+B) where A is the fair market value of the Licensed Product and B is the fair market value of the other product(s) in the combination sale. If the fair market value for any product sold in combination with a Licensed Product cannot be reasonably determined, the price attributed to such product will be based on the relative cost of goods for such product, as determined in accordance with GAAP. In addition, in the event that any Licensed Product is sold with any other product(s) or if any giveaways, discounts, rebates or charge-backs (whether as part of a customer loyalty, bundling or “loss leader” program, or otherwise) are provided for any Licensed Product to promote or sell other products or otherwise, the Net Sales for such Licensed Product shall be no less than the fair market value of such Licensed Product on a stand-alone basis (excluding any such discounts, rebates or charge-backs).

Upon exercise by Zogenix of its Option with respect to a Development Program, and from time to time thereafter, the Parties shall mutually agree upon any required amendments to Exhibit C.

(b) During the Term, Tevard shall maintain each of the Tevard In-Licenses in good standing and shall not take any action, or omit or fail to take any action (including making necessary payments), which would result in a breach or early termination of any such In-Licenses or any rights thereunder. Tevard covenants that it shall not amend, modify or supplement the terms of, or waive any rights under, any Tevard In-License without the prior written consent of Zogenix, which consent will not unreasonably be denied.

In instances where an Tevard In-License provides a right for Zogenix to receive a direct license from such Inbound Licensor in event of termination of such Tevard In-License, Tevard shall reasonably cooperate with Zogenix in obtaining such direct license. In instances where a

Tevard In-License does not already provide a right for Zogenix to receive a direct license from such Inbound Licensor, Tevard will use Commercially Reasonable Efforts to secure written statements from each Inbound Licensor declaring that, should the Tevard In-License be terminated, the applicable Inbound Licensor shall provide prompt notice thereof to Zogenix and shall grant a direct license to Zogenix on the same terms as those set forth in (a) this Agreement, or (b) the Tevard In-License, in each case which apply to the Inbound Licensor’s intellectual property that is sublicensed to Zogenix under the Tevard In-License.

Tevard shall transition all such activities to Zogenix in accordance with the Transition Plan at Zogenix’s cost and expense with respect to such transition activities. Without limiting the foregoing, Tevard shall disclose and deliver to Zogenix all tangible embodiments of all Tevard Know-How or Joint Know-How in its possession and Control that are useful or necessary to research, develop, make, use, sell, offer for sale or import the applicable Licensed Product, in each case to the extent not provided to Zogenix prior to such achievement of the Product Transfer Criteria, and all Books and Records related to such Licensed Product (provided that, with respect to any Books and Records related to both such Licensed Product and any other Products remaining with Tevard, Tevard may retain copies of such Books and Records for use in another Licensed Development Program, which copies shall be subject to the confidentiality covenants set forth in Article 9, provided that Tevard may disclose such Books and Records to an Inbound Licensor solely to the extent required under an In-License). Tevard shall make such Tevard Know-How or Joint Know-How available in a mutually agreed upon format and where feasible in electronic form; provided that, if Zogenix requests a form other than the form in which Tevard otherwise maintains such Tevard Know-How or Joint Know-How then Zogenix shall reimburse Tevard for all Out of Pocket Expenses incurred by Tevard in converting such Tevard Know-How or Joint Know-How to the form requested by Zogenix.

5.2.1 Tevard’s Option to Participate in Clinical Development of Dravet Syndrome Program. At any time after [***] but at [***] before Initiation of [***] Zogenix shall provide to Tevard the Tevard Option Information Package.

(b) Within thirty (30) days after the end of each Calendar Year (or partial Calendar Year) following Tevard’s exercise of the Tevard Option, Zogenix shall perform a true-up for all FTE Costs and Out-of-Pocket Expenses actually incurred during the applicable Calendar Year (or partial Calendar Year) with respect to which Tevard Pre-Payments have been paid by Tevard to reconcile the FTE Costs and Out-of-Pocket Expenses that were actually incurred during such Calendar Year (or partial Calendar Year) with the Tevard Pre-Payment that was paid by Tevard with respect thereto. Zogenix shall provide to Tevard its cost accounting documentation and other information reasonably requested by Tevard to document the reconciliation.

(c) Each Party shall make reconciling payments to the other as necessary to effect such true-up with respect to the FTE Costs and Out-of-Pocket Expenses for such Calendar Year (or partial Calendar Year). If Tevard is required to make a payment to Zogenix to effect such reconciliation, then Tevard shall provide such payment to Zogenix within twenty-one (21) days of the determination of such payment. If Zogenix is required to make a payment to Tevard to effect such reconciliation, Zogenix shall offset such amount against future amounts owed by Tevard to Zogenix pursuant to this Section 5.2.2.

5.2.3 Failure to Make Tevard Pre-Payment. If Tevard fails to make a Tevard Pre-Payment when due, Zogenix shall provide Tevard with written notice of such failure (a “Pre-Payment Failure Notice”). Timely upon receipt of such a Pre-Payment Failure Notice, Tevard may provide written notice to Zogenix detailing any amounts in dispute, which dispute Zogenix and Tevard shall seek to resolve in accordance with Section 13.1. If Tevard fails to make an undisputed Tevard Pre-Payment (or the undisputed amount of a Tevard

Pre-Payment) within sixty (60) days following receipt of a Pre-Payment Failure Notice, Tevard’s exercise of the Tevard Option shall be deemed cancelled as if such exercise had not occurred.

5.2.4 Cancellation of Tevard Option. Tevard may cancel its exercise of the Tevard Option for any or no reason by providing [***] written notice of such cancellation to Zogenix. For the avoidance of doubt, if Tevard elects to cancel its exercise of the Tevard Option for convenience as set forth in this Section 5.2.4, Tevard shall be obligated to make any Tevard Pre-Payment that comes due during such [***] notice period, and Tevard shall not be entitled to any refund or credit for amounts that it may have paid as Tevard Pre-Payments prior to cancellation (other than amounts that may be payable or creditable to Tevard as a final reconciliation) and Tevard shall not be entitled to any increased royalty rates on Net Sales of Licensed Products and the Optioned Dravet Product shall be deemed a Licensed Product.

5.2.5 Responsibility for Development and Commercialization.

Zogenix’s royalty obligations to Tevard under this Section 6.5 shall commence on a country-by-country and Licensed Product-by-Licensed Product basis on the date of the First Commercial Sale by Zogenix, its Affiliates, Licensees, or Sublicensees of the relevant Licensed Product in the relevant country and shall expire on a country-by-country basis and Licensed Product-by-Licensed Product basis on the latest of the following, as applicable: (a) the expiration of Patent-Based Exclusivity with respect to such Licensed Product in such country, (b) the expiration of Regulatory-Based Exclusivity with respect to such Licensed Product in such country, and (c) the tenth (10th) anniversary of the First Commercial Sale of such Licensed Product in such country by Zogenix, its Affiliates, Licensees, or Sublicensees, provided that there is Patent-Based Exclusivity for the Licensed Product in at least one country in the Territory at the time of such First Commercial Sale (the “Royalty Term”). The foregoing provisions of this Section 6.5 notwithstanding, the royalties payable with respect to Net Sales of Licensed Products shall be reduced, on a Licensed Product-by-Licensed Product and country-by-country basis, [***] of the amounts otherwise payable pursuant to Section 6.5.1 (with respect to Licensed Products [***]. Notwithstanding anything to the contrary herein, in no event shall the aggregate royalty payment, as adjusted by this Section 6.5.3, due from Zogenix to Tevard with respect to the Development, Commercialization and Manufacture of a Licensed Product be less than the aggregate amount that Tevard is required to pay to the Inbound Licensors of the Tevard In-License with respect to such Licensed Product. If any amount that Zogenix is entitled to deduct from the royalty payments due to Tevard under Section 6.5.1 with respect to a Licensed Product is not fully offset against such royalty amounts as a result of the preceding sentence, such amount may be carried forward and applied to future periods until fully exhausted.

(b) Future In-Licenses.

(i) Notwithstanding anything to the contrary herein, Zogenix shall have the right, without seeking the consent of the JDC, to independently negotiate a license to any additional technology or intellectual property (including any Patents) if necessary or useful to Develop, Commercialize or Manufacture a Product without infringing such intellectual property, including as part of settlement of any claim, litigation or administrative proceedings (“Additional Third Party IP”). For clarity, Tevard shall not, without Zogenix’s prior written consent, enter into any license agreement for Additional Third Party IP applicable to any Licensed Development Program or Covering any Licensed Product. With respect to any such license agreement that Tevard is interested in entering into, Tevard shall provide Zogenix with a reasonable opportunity to review and comment on the proposed terms of such license that would be applicable to Zogenix as a sublicensee thereunder, and shall incorporate and advocate for such terms in negotiating such license.

(ii) On a Licensed Product-by-Licensed Product basis, if Zogenix directly obtains a license or other agreement to any Additional Third Party IP that is necessary or useful to Develop, Commercialize or Manufacture a Product, such license shall automatically be deemed an “In-License” and Zogenix shall have the right to deduct [***] of the amounts paid by Zogenix under any In-License from any royalty payments due to Tevard under Section 6.5.1 with respect to the applicable Licensed Product, provided that, in no event shall such royalty payments due to Tevard under Section 6.5.1 be reduced to [***] of the full amount set forth in Section 6.5.2 as the result of any such deduction under this Section 6.5.3(b)(ii). If any amount that Zogenix is entitled to deduct from the royalty payments due to Tevard under Section 6.5.1 with respect to a Licensed Product is not fully offset against such royalty amounts as a result of the preceding sentence, such amount may be carried forward and applied to future periods until fully exhausted.

(iii) If during the Term, Tevard believes that a license to Additional Third Party IP is necessary or useful to Develop, Commercialize or Manufacture a Product, Tevard shall promptly provide Zogenix, via the JDC, a written description of such Additional Third Party IP together with the proposed licensing terms

therefor. If the Parties are in agreement that such Additional Third Party IP should be licensed, then the Parties shall discuss which Party shall lead such negotiations and thereafter, the designated Party shall use good faith efforts to license such Additional Third Party IP. The negotiating Party shall provide the other Party with a reasonable opportunity to review and comment on the proposed terms of such license that would be applicable to such other Party as a sublicensee thereunder, and shall reasonably consider and advocate for such comments when negotiating the terms of such license.

(iv) If Tevard obtains a license or other agreement to Additional Third Party IP pursuant to Section 6.5.3(b)(iii), Tevard shall promptly provide to Zogenix a written description of such Additional Third Party IP, together with a true and correct copy of such license or other agreement. If Zogenix notifies Tevard in writing after receipt thereof that Zogenix elects to receive a sublicense of rights granted under such Third Party license agreement, then such Third Party license agreement shall be an “In-License” under this Agreement. Zogenix shall, in addition to the other payments made by Zogenix to Tevard pursuant to this Article 6, pay to Tevard [***] of the amounts payable by Tevard pursuant to such In-License with respect to the Development, Commercialization and Manufacture of Licensed Products hereunder, and the Parties shall coordinate such payments by Zogenix so that Tevard receives such payments prior to the dates on which Tevard is required to pay the applicable Inbound Licensor. Tevard shall use Commercially Reasonable Efforts to ensure that (A) the royalty payments applicable to the Licensed Products shall be no higher than those royalty payments applicable to any other products licensed thereunder (including any products of Tevard’s other licensees) and (B) the rights and obligations applicable to the Licensed Products shall be no more restrictive than those rights and obligations applicable to other products licensed thereunder (including any products of Tevard’s other licensees).

(c) Generic Product Competition. If, on a Licensed Product-by-Licensed Product, country-by-country and Calendar Quarter-by-Calendar Quarter basis, Generic Product Competition is present with respect to such Licensed Product in such country during such Calendar Quarter, then the royalties payable with respect to such Licensed Product pursuant to Section 6.5.1 in such country during such Calendar Quarter shall be reduced to [***] of the amounts otherwise payable pursuant to Section 6.5.1.

(d) Additional Royalty if Zogenix Challenges the University Patents. Should Zogenix bring an action seeking to invalidate any University Patent, Zogenix will pay an additional royalty to Tevard during the pendency of such action that is equal to the increased royalty that Tevard pays to CWRU under the CWRU License. These additional royalties shall not be refundable. Moreover, should the outcome of such action determine that any claim of a University Patent challenged by Zogenix is both valid and infringed by a Licensed Product, Zogenix will pay an additional royalty that is equal to the increased royalty that Tevard pays to CWRU under the CWRU License during the remainder of the royalty term under the CWRU License. During the pendency of any action seeking to invalidate any University Patent, Zogenix shall not pay the additional royalties into any escrow or other similar account but shall pay such additional royalty to Tevard. This Section 6.5.3(d) shall not apply to situations where (i) Zogenix is required to participate in such patent challenge pursuant to a subpoena or court order or participates in a proceeding that is initiated by a patent office and not at the instigation of Zogenix or its Affiliates, (ii) any assertion by Zogenix or its Affiliates relating to validity, patentability, scope, priority, construction, non-infringement, inventorship, ownership or enforceability as a defense in any legal proceeding, administrative proceeding or arbitration brought by CWRU, WIBR or their licensees (including Tevard) or assignees asserting infringement against Zogenix or its Affiliates or (iii) any dispute or challenge brought by a Third Party which subsequently becomes an Affiliate of Zogenix provided the Zogenix causes such Third Party to initiate rescission of such dispute or challenge within sixty (60) days after such Third Party becomes an Affiliate of the Zogenix . For clarity, this Section 6.5.3(d) shall not apply to arguments made by Zogenix that distinguish the inventions claimed in patent applications owned or controlled by Zogenix from those claimed in the University Patents (a) in the ordinary course of ex parte prosecution of Zogenix’s patent applications or (b) in inter partes

proceedings before the United States Patent and Trademark Office or in any other agency or tribunal or court in any jurisdiction. For purposes of this Section 6.5.3(d), the term “University Patents” means those Patents licensed by Tevard pursuant to that certain License Agreement between Tevard and Case Western Reserve University, dated March 6, 2020 (the “CWRU License”) and those Patents licensed by Tevard pursuant to that certain License Agreement between Tevard and The Wistar Institute of Anatomy and Biology and the University of Iowa Research Foundation, dated September 22, 2020 (the “Wistar License”).

Section 6.6 Royalty Payments for Tevard Products.

6.6.1 Returned Development Programs. With respect to any Licensed Development Program that (i) becomes a Tevard Program subsequent to the filing of an IND with respect to such Development Program, if Tevard elects to Develop or Commercialize the Tevard Product(s) from such Tevard Program, Tevard shall pay Zogenix a royalty, on a Tevard Product-by-Tevard Product basis, on Net Sales of such Tevard Products by Tevard, its Affiliates, Licensees, or Sublicensees at the rate of [***], subject to the limitation in Section 6.6.2, or (ii) becomes a Tevard Program prior to the filing of an IND with respect to such Development Program, if Tevard elects to Develop or Commercialize Tevard Products, Tevard shall pay Zogenix a royalty, on a Tevard Product-by-Tevard Product basis, on Net Sales of such Tevard Products by Tevard, its Affiliates, Licensees, or Sublicensees at the rate of [***], subject to the limitation in Section 6.6.2. Payments due from Tevard to Zogenix under this Section 6.6.1 shall be paid on a Calendar Quarter basis within forty-five (45) days after the end of such Calendar Quarter.

6.6.2 Royalty Term for Tevard Products. Tevard’s royalty obligations to Zogenix under this Section 6.6 shall commence on a country-by-country and Tevard Product-by-Tevard Product basis on the date of First Commercial Sale by Tevard, its Affiliates, Licensees, or Sublicensees of the relevant Tevard Product in the relevant country and shall expire on a country-by-country and Tevard Product-by-Tevard Product basis on the latest of the following, as applicable: (a) the expiration of Patent-Based Exclusivity with respect to such Tevard Product in such country, (b) the expiration of Regulatory-Based Exclusivity with respect to such Tevard Product in such country, and (c) the tenth (10th) anniversary of the First Commercial Sale of such Tevard Product in such country by Tevard, its Affiliates, Licensees, or Sublicensees, provided that with respect to clause (c) there is Patent-Based Exclusivity for the Tevard Product in at least one country in the Territory at the time of such First Commercial Sale.

(a) Generic Product Competition. If, on a Tevard Product-by-Tevard Product, country-by-country and Calendar Quarter-by-Calendar Quarter basis, Generic Product Competition is present with respect to such Tevard Product in such country during such Calendar Quarter, then the royalties payable with respect to such Tevard Product pursuant to Section 6.6.1 in such country during such Calendar Quarter shall be reduced to [***] of the amounts otherwise payable pursuant to Section 6.6.1.

Section 6.7 Reports; Development and Sales Milestones; Royalty Payments. Until the expiration of a Party’s royalty and other payment obligations under this Article 6, such Party agrees to make written unaudited reports to the other Party within sixty (60) days after the end of each Calendar Quarter covering sales of Licensed Products or Tevard Products (as the case may be) on a product-by-product, country-by-country basis in the Territory by such Party, its Affiliates, Licensees, and Sublicensees during such Calendar Quarter. Each such written report shall provide (a) the Net Sales in Dollars and local currency for each Licensed Product in the Territory during the reporting period; and (b) the royalties payable, in Dollars, which shall have accrued hereunder with respect to such Net Sales. The information contained in each report under this Section 6.7 shall be considered Confidential Information of the Party providing the report. Concurrent with the delivery of each such report, the Party delivering such report shall make the royalty payment due the other Party under Article 6 for the Calendar Quarter covered by such report. In the case of

transfers or sales of any Licensed Product or Tevard Product (as applicable) between the royalty-paying Party and an Affiliate, Licensee or Sublicensee of such Party, a royalty shall be payable only with respect to the sale of such Licensed Product or Tevard Product to an independent Third Party that is not an Affiliate, Licensee or Sublicensee of the seller.

Section 6.8 Methods of Payments. All payments due from one Party (the “Payor”) to the other Party (the “Payee”) under this Agreement shall be paid in Dollars by wire transfer to a bank in the United States designated in writing by the Payee.

Section 6.9 Accounting.

6.9.1 Payor agrees to keep, and to require its Affiliates, Licensees, and Sublicensees to keep, full, clear and accurate records for a minimum period of three (3) years after the conclusion of the Calendar Year in which the relevant payment is owed pursuant to this Agreement, setting forth the sales and other disposition of Licensed Products and Tevard Products sold or otherwise disposed of in sufficient detail to enable royalties and compensation payable to the Payee hereunder to be determined.

6.9.2 Payor further agrees, upon not less than ninety (90) days prior written notice, to permit, and to require its Affiliates, Licensees, and Sublicensees to permit, the Books and Records relating to such Licensed Product and Tevard Product to be examined by an independent accounting firm selected by Payee and reasonably acceptable to Payor for the purpose of verifying reports provided by Payor under this Article 6. Such audit shall not be performed more frequently than once in any twelve (12)-month period or once with respect to any reporting period, and shall be conducted under appropriate confidentiality provisions, for the sole purpose of verifying the accuracy and completeness of all financial, accounting and numerical information and calculations provided under this Agreement. The independent accounting firm shall have reasonable access, on reasonable notice and during Payor’s normal business hours to individuals, records and responses to questions from auditors in a timely manner and have the right to make copies of relevant portions of Payor’s Books and Records; provided that, any such copies shall be the Confidential Information of Payor, shall be protected by appropriate confidentiality obligations and shall not be shared with Payee or any other Person.

6.9.3 Such examination is to be made at the expense of Payee, except if the results of the audit reveal an underpayment of royalties, milestones, or other payments to Payee under this Agreement of ten percent (10%) or more in any Calendar Year, in which case reasonable audit fees for such examination shall be paid by Payor.

Section 6.10 Currency. All amounts payable and calculations hereunder shall be in Dollars. When conversion of payments from any foreign currency is required to be undertaken by the Payor, the USD equivalent shall be calculated using Payor’s then-current standard exchange rate methodology as applied in its external reporting.

Section 6.11 Taxes and Withholding. Each Party shall be responsible for its own taxes, duties, levies, imposts, assessments, deductions, fees, withholdings or similar charges imposed on or measured by net income or overall gross income (including branch profits), gross receipts, capital, ability or right to do business, property, and franchise or similar taxes pursuant to Applicable Law. If the Payor is required to deduct or withhold from any payment due hereunder any taxes, duties, levies, imposts, assessments, deductions, fees, and other similar charges by Applicable Law or any Governmental Authority (“Withholding Taxes”), then the Payor shall pay such Withholding Taxes to the applicable Governmental Authority and make the payment to the Payee of the net amount due after deduction or withholding of such taxes, and such Withholding Taxes shall be treated for all purposes of this Agreement as having been paid to the Payee hereunder. The Payor shall submit to the Payee proof of payment of any Withholding Taxes

within a reasonable period of time after such Withholding Taxes are remitted to the Governmental Authority or, if sooner, within the period prescribed by Applicable Law. The Parties shall reasonably cooperate to eliminate or minimize any Withholding Taxes. To the extent commercially reasonable, the Payor shall provide to the Payee reasonable prior notice of its intention to withhold in order to allow the Payee reasonable opportunity to provide sufficient information or documentation to eliminate or minimize Withholding Taxes. The Payor shall timely provide reasonably sufficient documentation to enable the Payee to receive any credits available under applicable tax Laws. Payee shall indemnify and hold harmless Payor for any taxes, including Withholding Taxes, Payee owes to a Governmental Authority for which Payor is held responsible and for which prior withholding has not been made, and Payor shall hold Payee harmless for any fees, penalties and interest that are imposed on Payee arising out of Payor’s failure to withhold and remit Withholding Taxes to Governmental Authorities in accordance with this Section 6.11 and Applicable Laws, unless such failure arises from the acts or omissions of Payee (for example, the provision of incorrect beneficial owner information or invalid forms).

Section 6.12 Value Added Tax. Notwithstanding anything contained in Section 6.11, this Section 6.12 shall apply with respect to any value added tax, ad valorem, goods and services or similar tax chargeable on the supply or deemed supply of goods or services, sales and use taxes, transaction taxes, consumption taxes and other similar taxes required by Applicable Law including any interest, penalties or other additions to tax thereon, required under Applicable Law (“VAT”). All payments required under this Agreement are inclusive of VAT. If any VAT is required in respect of any such payment under Applicable Law, the Payor shall pay VAT at the applicable rate in respect of such payment as follows: (a) where the liability to collect, account for, or remit such VAT is a liability of the Payee, following the receipt of a valid VAT invoice in the appropriate form issued by the Payee in respect of such payment, such VAT to be payable on the later of the due date of the payment to which such VAT relates and forty-five (45) days after the receipt by the Payor of the applicable valid invoice relating to that VAT payment (provided, however, that the Payee shall return such VAT within a reasonable period of time to the extent that Payee actually receives under Applicable Law a refund or recovery of such VAT) or (b) where the liability to collect, account for, or remit such VAT is a liability of the Payor, timely account and pay for all applicable VAT to the proper tax authority. If the liability to collect, account for, or remit such VAT is a liability of Payee, the Payor shall not be responsible for any penalties, interest, and other additions thereon resulting from the failure by the Payee to collect (if not included on a valid VAT invoice) or remit any such VAT.

Section 6.13 Late Payments. Any undisputed amount owed by Payor to Payee under this Agreement that is not paid on or before the date such payment is due shall bear interest at a rate per annum equal to the lesser of the prime or equivalent rate per annum quoted by The Wall Street Journal on the first Business Day after such payment is due, plus two percent (2%), or the highest rate permitted by Applicable Law, calculated on the number of days such payments are paid after such payments are due and compounded monthly. Interest shall not accrue on undisputed amounts that were paid after the due date as a result of mistaken Payee actions (e.g., if a payment is late as a result of Payee providing an incorrect account for receipt of payment). In addition, the Payor shall reimburse the Payee for all costs, including attorneys’ fees and legal expenses, incurred in the collection of late payments; provided that, the foregoing shall not apply to payments disputed in good faith by the Payor unless the Payee is successful in such dispute or the Payor ceases to dispute such payments.

Section 7.1 During the Research Term. Except pursuant to Tevard’s Development responsibilities under this Agreement, during the Research Term, neither Tevard nor any of its Affiliates shall, except as otherwise permitted in Section 7.3, (a) either alone or with or for any Third Party, Develop, Manufacture or Commercialize any Corrective Therapeutic Agent for the diagnosis, amelioration, mitigation, prevention, treatment and/or cure of Epilepsy, or (b) grant a license or sublicense to Develop, Manufacture or Commercialize any Corrective Therapeutic Agent for the diagnosis, amelioration, mitigation, prevention, treatment and/or cure of Epilepsy.

Section 7.2 During the Term. Except pursuant to Tevard’s Development responsibilities under or otherwise pursuant to this Agreement, during the Term, neither Tevard nor any of its respective Affiliates shall, except as otherwise permitted in Section 7.3.1, (a) either alone or with or for any Third Party, Develop, Manufacture or Commercialize any Corrective Therapeutic Agent

(i) directed to Dravet Syndrome,

(ii) directed to any Indication to which any Licensed Product or Licensed Development Program is directed,

(iii) that is the same Corrective Therapeutic Agent contained in a Licensed Product,

(iv) that is directed to at least the same combination of Target(s) being developed or evaluated under a Development Program that becomes or may become a Licensed Development Program, or for which a Licensed Product is being Developed or Commercialized or a Licensed Program is directed, and/or

(v) that is a Protected Therapeutic Agent; or

(b) grant a license or sublicense or otherwise permit any Third Party to Develop, Manufacture or Commercialize any Corrective Therapeutic Agent as described in any of the foregoing (i) - (iv).

Section 7.3 Exceptions.

7.3.1 Subject to Section 2.4, the restrictions set forth in Section 7.1 and Section 7.2 shall not restrict either Party or its Affiliates from using Third Party contractors to perform Development, Manufacturing or Commercialization activities that such Party is permitted to perform directly under this Agreement.

7.3.2 The restrictions in Section 7.1 shall not prevent Tevard from Developing, Manufacturing or Commercializing any Corrective Therapeutic Agent inside the Field that is a Tevard Product, provided that such Developing, Manufacturing or Commercializing is not otherwise prohibited by Section 7.2.

Section 7.4 Protected Therapeutic Agents. On a [***] basis, Zogenix shall be permitted to nominate for discussion and mutual agreement by the JDC [***], certain Corrective Therapeutic Agents that, notwithstanding anything to the contrary herein, neither Tevard nor any of its respective Affiliates shall (a) [***] or (b) [***] (each a “Protected Therapeutic Agent”). For clarity, the restrictions in Section 7.2(v) and this Section 7.4 are in addition to the restrictions in Section 7.1 and Section 7.2(i) through (iv).

7.4.1 For each Licensed Development Program, Zogenix shall be permitted through the JDC to nominate for discussion and mutual agreement by the JDC up to [***] Protected Therapeutic Agents at any time for a period lasting until the occurrence of Product Transfer for such Licensed Development Program (each a “First Restricted List”). In addition, any time prior to Product Transfer for a Licensed Development Program Zogenix shall have the right through the JDC to nominate for discussion and mutual agreement by the JDC, the addition to such First Restricted List of one or more Corrective Therapeutic Agents or replacement of one or more Protected Therapeutic Agents on such First Restricted List with any other Corrective Therapeutic Agent, provided that (a) the number of Protected Therapeutic Agents for a particular

Licensed Development Program does not [***] and (b) that such nominated Corrective Therapeutic Agent is not already being actively Developed by Tevard outside of the Field, or subject to a written, final term sheet or other written, final agreement between Tevard and a Third Party pertaining to the Development of such Corrective Therapeutic Agent outside of the Field; in each case as demonstrated by written documentation (which upon request by Zogenix shall be confidentially disclosed by Tevard to Zogenix in a manner that protects Tevard’s sensitive business information).

7.4.2 Following the occurrence of Product Transfer for a Licensed Development Program, and for a period lasting until the Initiation of the first Pivotal Registration Trial for a Licensed Product from such Licensed Development Program, Zogenix shall be permitted through the JDC to nominate for discussion and mutual agreement by the JDC up to [***] Protected Therapeutic Agents from the First Restricted List for inclusion in a subsequent restricted list (each a “Second Restricted List”) for such Licensed Development Program. In addition, at any time prior to Initiation of the first Pivotal Registration Trial for a Licensed Product from such Licensed Development Program, Zogenix shall have the right through the JDC to nominate for discussion and mutual agreement by the JDC the addition to such Second Restricted List of one or more Corrective Therapeutic Agents or replacement of one or more Protected Therapeutic Agents on such Second Restricted List with any other Corrective Therapeutic Agent, provided that (a) the number of Protected Therapeutic Agents for a particular Licensed Development Program does not [***] and (b) that such nominated Corrective Therapeutic Agent is not already being actively Developed by Tevard outside of the Field, or subject to a written, final term sheet or other written, final agreement between Tevard and a Third Party pertaining to the Development of such Corrective Therapeutic Agent outside of the Field; in each case as demonstrated by written documentation (which upon request by Zogenix shall be confidentially disclosed by Tevard to Zogenix in a manner that protects Tevard’s sensitive business information). In addition, at Zogenix’s request, the Parties shall discuss in good faith the addition of further Corrective Therapeutic Agents to the Second Restricted List for a particular Licensed Development Program, thus increasing the number of Protected Therapeutic Agents for such Licensed Development Program above [***], but in no event more than [***].

7.4.3 Following the Initiation of the first Pivotal Registration Trial for a Licensed Product from a Licensed Development Program, and for a period lasting [***], Zogenix shall be permitted through the JDC to nominate for discussion and mutual agreement by the JDC, up to [***] Protected Therapeutic Agents from the Second Restricted List for inclusion in a subsequent restricted list (each a “Third Restricted List”) for such Licensed Development Program. In addition, at any time during the [***] period [***], Zogenix shall have the right through the JDC to nominate for discussion and mutual agreement by the JDC, the addition to such Third Restricted List of one or more Corrective Therapeutic Agents or replacement of one or more Protected Therapeutic Agents on such Third Restricted List with any other Corrective Therapeutic Agent, provided that (a) the number of Protected Therapeutic Agents for a particular Licensed Development Program [***] and (b) that such nominated Corrective Therapeutic Agent is not already being actively Developed by Tevard outside of the Field, or subject to a written, final term sheet or other written, final agreement between Tevard and a Third Party pertaining to the Development of such Corrective Therapeutic Agent outside of the Field; in each case as demonstrated by written documentation (which upon request by Zogenix shall be confidentially disclosed by Tevard to Zogenix in a manner that protects Tevard’s sensitive business information). In addition, at Zogenix’s request, the Parties shall discuss in good faith the addition of a further Corrective Therapeutic Agent to the Third Restricted List for a particular Licensed Development Program, thus increasing the number of Protected Therapeutic Agents for such Licensed Development Program above [***], but in no event more than [***].

7.4.4 Prior to the expiration of the period lasting until [***], Zogenix shall be permitted through the JDC to nominate for discussion and mutual agreement by the JDC, [***] from the Third Restricted List for inclusion in a subsequent restricted list (each a “Fourth Restricted List”) for such Licensed Development

Program, which restricted list shall last for the Term of such Licensed Development Program. For clarity, the Corrective Therapeutic Agents restricted under this Section 7.4.3 shall be in addition to those Corrective Therapeutic Agents restricted under Section 7.2(i) through (iv).

7.4.5 For clarity, each subsequent restricted list renders null and void any preceding restricted lists, and Tevard will not be prevented from Developing, Manufacturing or Commercializing, in accordance with any and all other restrictions under this Agreement, any Corrective Therapeutic Agent that was included in a prior restricted list but not included in a subsequent restricted list. Nothing in this Section 7.4 shall prevent Zogenix from nominating the same Corrective Therapeutic Agent for inclusion in a restricted list for more than one Licensed Development Program.

Section 7.5 Clarification. For clarity, this Article 7 shall not prevent Tevard from Developing, Manufacturing or Commercializing any vector (e.g., the AAV9 vector) for any other purpose solely due to Tevard’s use of such vector in a Licensed Product or Licensed Development Program.

As used in this Article 7, “Corrective Therapeutic Agents” means [***].

As used in this Article 7, a Corrective Therapeutic Agent shall be deemed the “same” as a reference Corrective Therapeutic Agent if the first Corrective Therapeutic Agent has [***].

[***].

As used in this Article 7, the term “tRNA anticodon sequence” means the three bases of the tRNA molecule that pair with the mRNA codon.

Section 8.1 Ownership of Inventions; Disclosure.

8.1.1 Ownership. Title to all Inventions and other intellectual property made solely by employees or agents of Tevard in the course of activities conducted pursuant to any Development Program shall be owned by Tevard; title to all Inventions and other intellectual property made solely by employees or agents of Zogenix in the course of activities conducted pursuant to any Development Program shall be owned by Zogenix; title to all Inventions and other intellectual property made jointly by employees or agents of Zogenix and Tevard in the course of activities conducted pursuant to any Development Program shall be owned jointly by Zogenix and Tevard. Inventorship of Inventions and other intellectual property made pursuant to this Agreement shall be determined in accordance with the patent laws and other applicable laws (including without limitation U.S. federal and state trade secret laws) of the United States. Except as expressly provided in this Agreement, neither Party shall have any obligation to account to the other for profits, or to obtain any approval of the other Party to license or exploit jointly-owned subject matter, by reason of joint ownership thereof, and each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting. For the avoidance of doubt, any jointly-owned Inventions and other intellectual property shall be deemed to be covered by the license granted under Section 4.2.1 and subject to the terms of this Agreement, including Article 7.

8.1.2 Disclosure of Inventions. Subject to Article 9 Tevard shall promptly disclose to Zogenix any Inventions made in connection with any Development Program, including any Licensed Development Program.

8.1.3 Background IP. Each Party shall retain ownership of intellectual property rights existing as of the Effective Date, or developed or acquired independently of any Development Program, and nothing in this Agreement shall assign any ownership to the other Party with respect to such intellectual property rights.

(b) Tevard shall notify Zogenix as to any decision to abandon, to cease Prosecution and Maintenance of, or to discontinue paying the expenses of Prosecution and Maintenance of, any such Tevard Patent or related Patent application in any country in which it was filed. Tevard will provide such notices at least thirty (30) days prior to any filing or payment due date, or any other due date that requires action, in connection with such Tevard Patent. Thereafter, Tevard shall, within 30 days or before a statutory dues date for responding to a patent authority or judicial body or due date for a paying a maintenance fee, whichever is sooner, assign to Zogenix such Tevard Patents or Tevard Patent applications for which Section 8.2.1(b) is applicable.

8.2.2 Zogenix Patents. Zogenix shall be responsible, at its expense, and shall have the exclusive right, but not the obligation, for preparing, filing, Prosecuting and Maintaining the Zogenix Patents and for conducting Defense Proceedings relating thereto.

8.2.3 Joint Patents.

(a) Zogenix shall be responsible for preparing, filing, Prosecuting and Maintaining Joint Patents arising in Development Programs to which Zogenix retains Option rights or in Licensed Development Programs (the “Zogenix-Prosecuted Joint Patents”) and for defending any administrative or judicial challenges to invalidity, title, or enforceability relating thereto.

Without limiting the foregoing, Zogenix shall (i) provide Tevard with copies of the text of the applications for such Zogenix-Prosecuted Joint Patents as soon as practical but at least ten (10) days before filing, except for urgent filings in which case Zogenix shall provide copies as soon as practical before, simultaneously with or immediately after filing; (ii) provide Tevard with a copy of each submission made to and material document received from a patent authority, court or other tribunal regarding any such Zogenix-Prosecuted Joint Patents reasonably promptly after making such filing or receiving such material document, including a copy of each application as filed together with notice of its filing date and application number; (iii) keep Tevard advised of the status of all material communications, actual and prospective filings or submissions regarding such Zogenix-Prosecuted Joint Patents, and shall give Tevard copies of any such material communications, filings and submissions proposed to be sent to any patent authority or judicial body; and (iv) consider in good faith Tevard’s comments on the material communications, filings and submissions for such Zogenix-Prosecuted Joint Patents.

(b) Zogenix shall notify Tevard as to any decision to abandon, to cease Prosecution and Maintenance of, or not to continue to pay the expenses of Prosecution and Maintenance of, any Zogenix-Prosecuted Joint Patent in any country in which it was filed. Zogenix will provide such notices at least thirty (30) days prior to any filing or payment due date, or any other due date that requires action, in connection with such Zogenix-Prosecuted Joint Patent. Thereafter, Tevard may, upon written notice to Zogenix, in both Parties’ names and at Tevard’s sole cost, control the filing for, Prosecution and Maintenance of such Zogenix-Prosecuted Joint Patents thereafter. Tevard will keep Zogenix reasonably informed of the status of the Zogenix-Prosecuted Joint Patents.

(c) Tevard shall be responsible for preparing, filing, prosecuting and maintaining Joint Patents other than the Joint Patents for which Zogenix has such responsibility pursuant to Section 8.2.3(a) (the “Tevard-Prosecuted Joint Patents”) and for conducting any Defense Proceedings relating thereto.

Tevard will provide such notices at least thirty (30) days prior to any filing or payment due date, or any other due date that requires action, in connection with such Tevard-Prosecuted Joint Patents. Thereafter, Tevard shall, within 30 days or before a statutory dues date for responding to a patent authority or judicial body or due date for a paying a maintenance fee, whichever is sooner, assign to Zogenix such Tevard-Prosecuted Joint Patents or Tevard-Prosecuted Joint Patent applications for which Section 8.2.1(d) is applicable.

8.2.4 Cooperation. Each Party shall reasonably cooperate with and assist the other Party in connection with the activities of such Party under this Section 8.2 upon the reasonable request of the other Party, including by making researchers and research records reasonably available and the execution of all such documents and instruments and the performance of such acts as may be reasonably necessary in order to permit the other Party to continue any filing, prosecution, maintenance or extension of such patents and patent applications, as well as any defense of any challenges to the validity, ownership, and enforceability of such patents and patent applications.

8.2.5 Patent Term Extension. Zogenix shall have the sole right to make decisions regarding, and to apply for, patent term extensions in the Territory, including in the United States with respect to extensions pursuant to 35 U.S.C. § 156 et. seq. and in other jurisdictions pursuant to supplementary protection certificates, and in all jurisdictions with respect to any other extensions that are now or become available in the future, wherever applicable, for all Zogenix Patents, Tevard Patents and Joint Patents with respect to Licensed Products, in each case including whether or not to so apply; provided, that for the Tevard Patents and the Joint Patents, Zogenix shall notify Tevard of Zogenix’s interest in obtaining extensions and consult with Tevard to determine the course of action with respect to such filings. Tevard shall provide prompt and reasonable assistance, as requested by Zogenix, including by taking such action as is required under any Applicable Law to obtain such extension or supplementary protection certificate. To the extent that Tevard has the right to make decisions regarding and applying for patent term extensions under an applicable In-License, Tevard shall exercise its rights to extend such Patents as directed by Zogenix. To the extent that Tevard does not have such right under an applicable In-License but can or is otherwise not prohibited from requesting patent term extensions under such In-License, Tevard shall request such patent term extension under such In-License and if the Inbound Licensor under such In-License consents, then Tevard shall exercise its rights to extend such Patents as directed by Zogenix.

Section 8.3 Enforcement and Defense.

8.3.1 Notice. Each Party shall promptly notify the other of any knowledge it acquires of any actual or suspected infringement or misappropriation of the Zogenix IP, Tevard IP, or Joint IP with respect to any Competitive Product, in each case by a Third Party.

8.3.2 Actions.

(a) If any Tevard IP or Joint IP relating to a Licensed Product or Licensed Development Program is infringed or misappropriated by a Third Party that is developing, manufacturing or commercializing a Competitive Product in any country in the Territory, then Zogenix shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to such infringement or misappropriation, by counsel of its own choice. If in any such proceeding brought by Zogenix, Tevard (or an Inbound Licensor) is required to join for standing purposes or in order for Zogenix to commence or continue any such proceeding, then Tevard (or an Inbound Licensor) shall join such proceeding, at Zogenix’s expense, and shall be represented in such proceeding by counsel of Tevard’s (or an Inbound Licensor’s) choice. The exercise by Zogenix of the right to bring an action shall be subject to and consistent

with the terms of all applicable In-Licenses; provided that, if, under the terms of an applicable In-License, Tevard has an applicable enforcement right that it cannot delegate to Zogenix then, at Zogenix’s request and expense, Tevard shall exercise such rights in such enforcement action as directed by Zogenix. If Zogenix does not take action in the prosecution, prevention, or termination of any infringement or misappropriation pursuant to this Section 8.3.2(a), and has not commenced negotiations with the suspected malfeasor for the discontinuance of said malfeasance, then, within ninety (90) days after receipt of notice of the existence of an infringement or misappropriation (or in cases where there is a relevant statutory period during which an enforcement action must be commenced that would expire prior to the expiration of such ninety (90) day period and of which Tevard has notified Zogenix promptly after it becomes aware, then no less than fifteen (15) days prior to the expiration of such relevant statutory period), Tevard and Zogenix shall meet and discuss Zogenix’s reasons for not initiating a lawsuit or otherwise making or prosecuting a claim. If thereafter, Tevard (or an Inbound Licensor) desires to initiate a lawsuit or otherwise make or prosecute a claim regarding a Tevard Patent with respect to the Competitive Product, Tevard shall so notify Zogenix and Tevard (or an Inbound Licensor) may, so long as Zogenix has not objected in writing within ten (10) Business Days of receipt of Tevard’s notification, institute, prosecute, and control such action; provided that Tevard (or an Inbound Licensor) shall not enter into any settlement, consent judgment or other final disposition of such action in any manner that diminishes the rights or interests of Zogenix, including, without limitation, (i) restricting the scope, or adversely affecting the enforceability of Zogenix’s intellectual property rights, including any rights granted to Zogenix under this Agreement (ii) requiring Zogenix to make a payment, (iii) requiring Zogenix to make an admission of legal wrongdoing in any way, and (iv) effecting an amendment of this Agreement, without the prior written consent of Zogenix. If in any such proceeding Zogenix is required to join for standing purposes or in order for Tevard (or an Inbound Licensor) to commence or continue any such proceeding, then Zogenix shall join such proceeding, at Tevard’s (or Inbound Licensor’s, as applicable) request and expense, and shall be represented in such proceeding by counsel of Zogenix’s choice.

(b) Any and all expenses, including reasonable attorneys’ fees, incurred by each Party (or an Inbound Licensor, as applicable) with respect to the prosecution, adjudication and/or settlement of a lawsuit or enforcement action in accordance with this section, including any related appeals, shall be paid entirely by the Party (or an Inbound Licensor, as applicable) that incurred the expenses.

(c) The party initiating the suit shall have the sole and exclusive right to elect counsel for any suit initiated by it pursuant to Section 8.3.2(a); provided that such counsel is reasonably acceptable to the other Party. The other Party (and/or an Inbound Licensor) shall have the right to participate in and be represented by counsel of its own selection and at its own expense in any suit instituted under Section 8.3.2(a) by the other Party for infringement or misappropriation.

(d) Each Party agrees to cooperate fully in any action under this Section 8.3.2 that is controlled by the other Party, including executing legal papers and cooperating in the prosecution as may be reasonably requested by the Controlling Party.

(e) If any Joint IP or Tevard IP relating to a Tevard Product is infringed or misappropriated by a Third Party in any country in the Territory, then Tevard shall have the sole right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to such malfeasance, by counsel of its own choice. If in any such proceeding Zogenix is required to join for standing purposes or in order for Tevard to commence or continue any such proceeding, then Zogenix shall join such proceeding, at Tevard’s expense, and shall be represented in such proceeding by counsel of Zogenix’s choice.

(f) Unless otherwise agreed by the Parties in writing, the amount of any recovery from a proceeding brought under Section 8.3.2 shall first be applied to the Out-of-Pocket costs of such action by the Party prosecuting the applicable action, and (A) if the prosecuting Party is the Party (together with its

Affiliates, Licensees, and Sublicensees) Commercializing the applicable Licensed Product or Tevard Product affected by the infringing Competitive Product, any remaining recovery amount shall be treated as Net Sales hereunder and the prosecuting Party shall pay royalties thereon in accordance with Section 6.5.1 or Section 6.6, as applicable, or (B) otherwise, any remaining recovery amount shall be allocated first, such percentage owed to the Inbound Licensor pursuant to the applicable Tevard In-License, and then, of the remaining amount, [***]. If in connection with a proceeding brought under Section 8.3.2, an In-License counterparty is entitled to a portion of any recovery that is greater than the portion of the recovery payable, after costs, to Tevard, the Parties will meet and agree in good faith on an alternative sharing of such recovery to that set forth in the immediately preceding sentence that takes into account the amounts payable to the applicable In-License counterparties and results in an equitable allocation of the amounts remaining to Zogenix and Tevard after payment of such amounts to the applicable In-License counterparties.

(g) For avoidance of doubt, in the event that the European Unified Patent Court (“UPC”) comes into existence, the decision on whether to opt-in or opt-out of the UPC for any Tevard Patents, Zogenix Patents or Joint Patents shall be made by Zogenix in Zogenix’s sole discretion; provided that, as to Tevard Patents or Joint Patents specifically relating to a Tevard Product, Tevard shall make such decision from and after the time the applicable product becomes a Tevard Product.

8.3.3 Biosimilar Applications. Notwithstanding the provisions of Section 8.3.2, if either Party receives a copy of a Biosimilar Application referencing a Licensed Product, whether or not such notice or copy is provided under any Applicable Laws (including under the BPCIA, the United States Patient Protection and Affordable Care Act, or its successor provisions), or otherwise becomes aware that such a Biosimilar Application has been submitted to a Regulatory Authority for marketing authorization (such as in an instance described in 42 U.S.C. §262(l)(2)), the remainder of this Section 8.3.3 shall apply. Such Party will promptly, but in any event within ten (10) Business Days, notify the other Party. The owner of the relevant Patents will then seek permission to view the Biosimilar Application, information regarding the process or processes used to manufacture the product that is the subject of the Biosimilar Application, and related confidential information from the filer of the Biosimilar Application if necessary under 42 U.S.C. §262(l)(1)(B)(iii). If either Party receives any equivalent or similar communication or notice in the United States or any other jurisdiction, the Party receiving such communication or notice will within five (5) business days notify the other Party of such communication or notice to the extent permitted by Applicable Laws. Regardless of the Party that is the “reference product sponsor,” as defined in 42 U.S.C. §262(l)(1)(A), for purposes of such Biosimilar Application:

(a) Zogenix will designate, to the extent permitted by Applicable Law, or otherwise Tevard will designate in accordance with Zogenix’s instructions, the outside counsel and in-house counsel who will receive confidential access to the Biosimilar Application, information regarding the process or processes used to manufacture the product that is the subject of the Biosimilar Application, and any related confidential information pursuant to 42 U.S.C. §262(l)(1)(B)(ii).

(b) In each case, after consulting with Tevard and considering Tevard’s comments in good faith, Zogenix shall have the right to (a) list any patents, including those Patents within the Tevard Patents, as required pursuant to 42 U.S.C. §262(l)(3)(A) or 42 U.S.C. §262(l)(7), (b) respond to any communications with respect to such lists from the filer of the Biosimilar Application, (c) negotiate with the filer of the Biosimilar Application as to whether to utilize a different mechanism for information exchange other than that specified in 42 U.S.C. §262(l)(1), and (d) as to the Patents that will be subject to the litigation procedure as described in 42 U.S.C. §262(l)(4), decide which Patent or Patents will be selected for litigation under 42 U.S.C. §262(l)(5)(B)(i)(II), and commence such litigation under 42 U.S.C. §262(l)(6). If Tevard is required pursuant to Applicable Law to execute any of these tasks it will do so in accordance with Zogenix’s instructions.

(c) Tevard shall cooperate with Zogenix’s reasonable requests in connection with the foregoing activities to the extent required or permitted by Applicable Laws. Zogenix shall consult with Tevard prior to identifying any Patents within the Tevard Patents to a Third Party as contemplated by this Section 8.3.3. Zogenix shall consider in good faith advice and suggestions with respect thereto received from Tevard, and notify Tevard of any such lists or communications promptly after they are made

(d) Each Party will within five (5) Business Days after receiving any notice of commercial marketing provided by the filer of a Biosimilar Application pursuant to 42 U.S.C. §262(l)(8)(A), notify the other Party. To the extent permitted by Applicable Law, Zogenix will have the first right, but not the obligation, to seek an injunction against such commercial marketing as permitted pursuant to 42 U.S.C. §262(l)(8)(B) and to file an action for infringement. If required pursuant to Applicable Law, upon Zogenix’s request, Tevard will assist in seeking such injunction or filing such infringement action after consulting with Zogenix. Except as otherwise provided in this Section 8.3.3, any action contemplated by this section will be subject to the other terms and conditions of Section 8.3.2.

8.3.4 Defense. With respect to any defense or declaratory judgment actions relating to a Tevard Patent, a Zogenix Patent or a Joint Patent, including any Defense Proceeding, the Party with responsibility for the prosecution of such Patent shall have the first right, but not the obligation, to assume the defense thereof at its sole cost and expense. With respect to any Defense Proceeding relating to a Joint Patent, if the Party with responsibility for the prosecution of the Joint Patent declines to assume the defense of such Patent, then the other Party shall have the right, but not the obligation, to assume the defense thereof at its sole cost and expense. For the avoidance of doubt, with respect to any Defense Proceeding relating to Tevard Patents, Tevard shall have the sole right, but not the obligation to assume the defense thereof at its sole cost and expense; provided, that Zogenix has the right, at its sole cost and expense, to join any such defense with counsel of its choice. With respect to any Defense Proceeding relating to Zogenix Patents, Zogenix shall have the sole right, but not the obligation to assume the defense thereof at its sole cost and expense. Each Party agrees to render such reasonable assistance as the defending Party may request, at the defending Party’s expense, with respect to actions brought pursuant to this Section 8.3.4.

Section 8.4 Infringement Claimed by Third Parties.

8.4.1 In the event a Third Party commences, or threatens to commence, any proceeding against a Party to this Agreement alleging infringement of a Third Party’s intellectual property by the Development, Manufacture, Commercialization, use, sale, offer for sale, export and/or import by Zogenix, its Affiliates, Licensees, or Sublicensees of any Licensed Product, the Party against whom such proceeding is threatened or commenced shall give prompt notice to the other Party.

8.4.2 Unless the Party against whom such proceeding is filed seeks indemnification for a claim covered pursuant to Article 11, such Party shall control the defense and settlement of any such proceeding under this Section 8.4.2 at its own cost.

Section 9.1 Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that the receiving Party (the “Receiving Party”) shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as provided for in this Agreement any Know-How or other confidential and proprietary information and materials, patentable or otherwise, in any form (written, oral, photographic, electronic, magnetic, or

otherwise) which is disclosed to it by the other Party (the “Disclosing Party”) or otherwise received or accessed by a Receiving Party in the course of performing its obligations or exercising its rights under this Agreement, including trade secrets, Know-How, inventions or discoveries, proprietary information, formulae, processes, techniques and information relating to a Party’s past, present and future marketing, financial, and Development activities of any product or potential product or useful technology of the Disclosing Party and the pricing thereof (collectively, “Confidential Information”), except to the extent that it can be established by the Receiving Party that such Confidential Information:

9.1.1 was in the lawful knowledge and possession of the Receiving Party prior to the time it was disclosed to, or learned by, the Receiving Party, or was otherwise developed independently by the Receiving Party, as evidenced by written records kept in the ordinary course of business, or other documentary proof of actual use by the Receiving Party;

9.1.2 was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

9.1.3 became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the Receiving Party in breach of this Agreement; or

9.1.4 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.

For the avoidance of doubt, any information disclosed by Tevard to Zogenix on or prior to the Effective Date pursuant to any non-disclosure agreements by and between Tevard and Zogenix, including that certain Option Agreement For Exclusive License, dated October 14, 2019, (the “Existing Confidentiality Agreements”) shall be Confidential Information of Tevard and Tevard Know-How for all purposes under this Agreement, provided that all Joint Know-How and all Tevard Know-How and Confidential Information related to any Licensed Development Program, irrespective of which Party is the Disclosing Party, shall be deemed the Confidential Information of Zogenix.

Section 9.2 Authorized Disclosure. Except as expressly provided otherwise in this Agreement, a Receiving Party may use and disclose Confidential Information of the Disclosing Party as follows: (a) under appropriate confidentiality provisions similar to those in this Agreement, in connection with the performance of its obligations or exercise of rights granted or reserved in this Agreement (including the rights to Develop and Commercialize Licensed Products and to grant licenses and sublicenses hereunder); or (b) to the extent such disclosure is reasonably necessary in filing or prosecuting patent, copyright and trademark applications, prosecuting or defending litigation, complying with applicable governmental regulations, seeking and obtaining Regulatory Approval, conducting non-clinical activities or clinical trials, preparing and submitting INDs or other filings to Regulatory Authorities, responding to inquiries from a Governmental Authority, or is otherwise required by Law, the rules of a recognized stock exchange or automated quotation system applicable to such Party; provided, however, that if a Receiving Party desires to respond to an inquiry from a Governmental Authority or is required by Law to make any such disclosure of a Disclosing Party’s Confidential Information it will, except where impracticable, give reasonable advance notice to the Disclosing Party of such disclosure requirement and, if requested by the Disclosing Party, cooperate with the Disclosing Party to secure confidential treatment of such Confidential Information required to be disclosed; or (c) in communication with existing or prospective investors, consultants, advisors, licensors, licensees, or collaborators or others on a need to know basis, in each case under appropriate confidentiality provisions substantially equivalent to those of this Agreement; or (d) to the extent mutually agreed to in writing by the Parties.

Each Party agrees not to issue any press release or other public statement, whether oral or written, disclosing the existence of this Agreement, the terms hereof or any information relating to this Agreement without the prior written consent of the other Party (which consent shall not be unreasonable withheld, delayed or conditioned).

9.3.2 Public Disclosures and Publications Related to Development Programs and/or Products. Any proposed public disclosure (whether written, electronic, oral or otherwise) by either Party relating to any Development Program or any Product shall require the prior written consent of the other Party (which consent shall not be unreasonable withheld, delayed or conditioned). The Party desiring disclosure shall first provide to the other Party written notice of its intent to disclose and a draft of such proposed disclosure and the other Party shall have thirty (30) days after receipt of the draft disclosure to provide consent or request in writing the removal of portions deemed by such Party to contain confidential or patentable material owned by such Party, or to request a delay pending such Party’s application for patent protection. Notwithstanding the foregoing, this Section 9.3.2 shall not apply to information which is in the public domain, nor shall it apply to Zogenix with respect to Development Programs that have become either Licensed Development Programs or Zogenix Development Programs or Products that have become Licensed Products.

9.3.3 Disclosures Required by Law. Notwithstanding the provisions of Sections 9.3.1 and 9.3.2, each Party may make any disclosures required of it to comply with any duty of disclosure it may have pursuant to law or governmental regulation or pursuant to the rules of any recognized stock exchange (“Securities Laws”). In the event of a disclosure required by Securities Laws, the Parties shall coordinate with each other with respect to the timing, form and content of such required disclosure. If so requested by the other Party, the Party subject to such obligation shall reasonably cooperate with efforts undertaken by the requesting Party to obtain an order protecting to the maximum extent possible the confidentiality of such provisions (including financial terms) of this Agreement as reasonably requested by the other Party. If the Parties are unable to agree on the form or content of any required disclosure, such disclosure shall be limited to the minimum appropriate disclosure, as reasonably determined by the disclosing Party in consultation with its legal counsel.

The Party not controlling such defense may participate therein at its own expense; provided that, except with respect to an indemnification obligation for an infringement Claim under Section 11.1.1(d), if the Indemnifying Party assumes control of such defense and the Indemnified Party in good faith concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnifying Party shall be responsible for the reasonable fees and expenses of one counsel to the Indemnified Party in connection therewith. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party.

Section 11.4 Insurance. Each Party shall procure and maintain general liability and product liability insurance as follows:

Each Party shall notify the other Party at least fifteen (15) days prior to cancellation of any such coverage.

No Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure is defined as causes beyond the control of the Party, including acts of God; material changes in Law; actions or failures in action by relevant Governmental Authorities; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; shortages of supply; labor disturbances; epidemic; and failure of public utilities or common carriers. In such event Tevard or Zogenix, as the case may be, shall immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of ninety (90) days, after which time Tevard and Zogenix shall promptly meet to discuss in good faith how to best proceed in a manner that maintains and abides by the Agreement. Without limiting the foregoing, if claims excuse for any failure to perform during the Research Term, the Research Term shall automatically be extended pro-rata for each day that Tevard claims such excuse. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

Section 13.8 Notices. Any notice or request required or permitted to be given under or in connection with this Agreement shall be deemed to have been sufficiently given if in writing and personally delivered or sent by certified mail (return receipt requested), facsimile transmission (receipt verified), or overnight express courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:

or to such other address for such Party as it shall have specified by like notice to the other Parties, provided that, notices of a change of address shall be effective only upon receipt thereof. If delivered personally or by facsimile transmission, the date of delivery shall be deemed to be the date on which such notice or request was given. If sent by overnight express courier service, the date of delivery shall be deemed to be the next Business Day after such notice or request was deposited with such service. If sent by certified mail, the date of delivery shall be deemed to be the third (3rd) Business Day after such notice or request was deposited with the U.S. Postal Service.

Section 13.9 Export Control. Each Party acknowledges that the Laws of the United States restrict the export and re-export of commodities and technical data of United States origin. Each Party agrees that it will not export or re-export restricted commodities or the technical data of the other party in any form without the appropriate United States and foreign government licenses.

Section 13.10 Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing. The failure of either Party to assert a right hereunder or to insist upon compliance with any term of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition. No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver of such condition or term or of another condition or term.

Section 13.11 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.

Section 13.12 Entire Agreement. This Agreement, together with the Schedules and Exhibits hereto, set forth all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto and supersede and terminate all prior agreements and understanding between the Parties. In particular, and without limitation, this Agreement supersedes and replaces the Existing Confidentiality Agreements and any and all term sheets relating to the transactions contemplated by this Agreement and exchanged between the Parties prior to the Effective Date. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as set forth herein and therein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties hereto unless reduced to writing and signed by the respective authorized officers of the Parties.

Section 13.13 Independent Contractors. Nothing herein shall be construed to create any relationship of employer and employee, agent and principal, partnership or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either directly or indirectly, any liability of or for the other Party. Neither Party shall have the authority to bind or obligate the other Party and neither Party shall represent that it has such authority.

Section 13.14 Headings; Construction; Interpretation. Headings used herein are for convenience only and shall not in any way affect the construction of or be taken into consideration in interpreting this Agreement. The terms of this Agreement represent the results of negotiations between the Parties and their representatives, each of which has been represented by counsel of its own choosing, and neither of which has acted under duress or compulsion, whether legal, economic or otherwise. Accordingly, the terms of this Agreement shall be interpreted and construed in accordance with their usual and customary meanings, and each of the Parties hereto hereby waives the application in connection with the interpretation and construction of this Agreement of any rule of Law to the effect that ambiguous or conflicting terms or provisions contained in this Agreement shall be interpreted or construed against the Party whose attorney prepared the executed draft or any earlier draft of this Agreement. Any reference in this Agreement to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit shall be deemed to be a reference to any Article, Section, subsection, paragraph, clause, Schedule or Exhibit, of or to, as the case may be, this Agreement. Except where the context otherwise requires, (a) any definition of or reference to any agreement, instrument or other document refers to such agreement, instrument other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein or therein), (b) any reference to any Law refers to such Law as from time to time enacted, repealed or amended, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, refer to this Agreement in its entirety and not to any particular provision hereof, (d) the words “include,” “includes,” “including,” “exclude,” “excludes,” and “excluding,” shall be deemed to be followed by the phrase “but not limited to,” “without limitation” or words of similar import, and (e) the word “or” is used in the inclusive sense (and/or).

Section 13.15 Financial Books and Records. Any financial Books and Records to be maintained under this Agreement by a Party or its Affiliates, Licensees, or Sublicensees and subject to an audit right hereunder shall be maintained in accordance with GAAP.

Section 13.16 Further Actions. Each Party shall execute, acknowledge and deliver such further instruments, and do all such other acts, as may be necessary or appropriate in order to carry out the expressly stated purposes and the clear intent of this Agreement.

Section 13.17 Parties in Interest. All of the terms and provisions of this Agreement shall be binding upon, and shall inure to the benefit of and be enforceable by the Parties hereto and their respective successors, heirs, administrators and permitted assigns.

Section 13.18 Performance by Affiliates. Tevard acknowledges and agrees that Zogenix may perform some or all of its obligations under this Agreement through its Affiliates; provided, however, that Zogenix shall remain responsible for the performance by its Affiliates and will cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. To the extent that this Agreement imposes obligations on Affiliates of a Party, such Party agrees to cause its Affiliates to perform such obligations.

Section 13.19 Counterparts. This Agreement may be signed in counterparts, each and every one of which shall be deemed an original, notwithstanding variations in format or file designation which may result from the electronic transmission, storage and printing of copies from separate computers or printers.

1.License Agreement between Case Western Reserve University and Tevard Biosciences, Inc., dated March 6, 2020.

2.License Agreement between The Wistar Institute of Anatomy and Biology, University of Iowa Research Foundation and Tevard Biosciences, Inc., dated September 22, 2020.

FOR VALUE RECEIVED, Tevard Biosciences, Inc., a Delaware corporation (the “Company”), hereby promises to pay Zogenix, Inc. ( “Lender”), the principal balance equal to $5,000,000, together with simple interest on the unpaid principal balance of this Note from time to time outstanding at the rate of 3.5% per year; provided that in no event shall the interest rate be less than the minimum rate of interest required in order to avoid the imputation of interest for federal income tax purposes. Interest shall commence with the date hereof and shall continue on the outstanding unpaid principal until paid in full or converted. Interest on this Note shall be computed on the basis of a year of 365 days for the actual number of days elapsed.

1. Maturity. Unless earlier converted pursuant to the conversion provisions set forth herein, all outstanding principal and accrued interest under this Note (the “Outstanding Amount”) shall be due and payable by the Company December 3, 2022 (the “Maturity Date”).

2. Conversion of the Note. Effective upon the closing of a Qualified Financing (as defined below), the Outstanding Amount shall automatically be converted into shares of the same class and series of capital stock of the Company issued to other investors in the Qualified Financing (the “Conversion Shares”) at a conversion price equal to the price paid per share for the Equity Securities (as defined below) by the other investors in the Qualified Financing (the “Conversion Price”), with any resulting fraction of a share rounded down to the nearest whole share. No payment will be made to Lender in lieu of any fractional shares to which Lender would otherwise have been entitled, and such amounts shall be extinguished without any further payment on the part of the Company. The number of Conversion Shares to be issued upon such conversion shall be equal to the quotient obtained by dividing the Outstanding Amount on this Note, on the date of conversion, by the Conversion Price. “Qualified Financing” means the first issuance or series of related issuances by the Company of Equity Securities following the date of this Note from which the Company receives immediately available gross proceeds of at least $10 million (excluding proceeds from this Note and any other indebtedness of the Company that

convert into equity in such financing). The Company shall notify Lender in writing of the anticipated occurrence of a Qualified Financing at least five days prior to the closing date of the Qualified Financing, notifying Lender of the conversion to be effected and the terms under which the Equity Securities of the Company are anticipated to be sold in such Qualified Financing. The issuance of Conversion Shares pursuant to the conversion of this Note shall be upon and subject to the same terms and conditions applicable to the Equity Securities sold in the Qualified Financing. Lender hereby agrees to execute and become party to all customary agreements that the Company reasonably requests in connection with such Qualified Financing. As promptly as practicable after the conversion of this Note, the Company at its expense shall issue and deliver to the holder of this Note, upon surrender of this Note by Lender to the Company, a certificate or certificates for the number of full Conversion Shares issuable upon such conversion. Upon the conversion of this Note, Lender shall have no further rights under such Note, whether or not such Note is surrendered. “Equity Securities” means a series of the Company’s common stock or preferred stock issued by the Company for bona fide equity financing purposes.

3. Payment Upon Change of Control. If there is a Change of Control (as defined below) of the Company prior to the conversion of this Note for any reason, the Company shall pay to Lender, upon the closing of the Change of Control and in full satisfaction of this Note, the Change of Control Multiple (as defined below). The “Change of Control Multiple” means two times (2x) the outstanding principal balance of this Note. A “Change of Control” means (i) a merger or consolidation in which (x) the Company is a constituent party or (y) a subsidiary of the Company is a constituent party and the Company issues shares of its capital stock pursuant to such merger or consolidation, except any such merger or consolidation involving the Company or a subsidiary in which the shares of capital stock of the Company outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation or (2) if the surviving or resulting corporation is a wholly-owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation, (ii) the sale by the stockholders of the Company, in a single transaction or series of related transactions, of capital stock representing at least 50% of the outstanding voting power of the Company, or (iii) the sale, lease, transfer, exclusive license (but for clarity excluding any exclusive license in a specific field of use entered into in the ordinary course of business) or other disposition, in a single transaction or series of related transactions, by the Company or any subsidiary of the Company of all or substantially all the assets of the Company and its subsidiaries taken as a whole, or the sale or disposition (whether by merger, consolidation or otherwise) of one or more subsidiaries of the Company if substantially all of the assets of the Company and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the Company; provided that a Change of Control shall not include any transaction or series of related transactions principally for bona fide equity financing purposes (including, but not limited to, the Qualified Financing) in which cash is received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof occurs. The Company shall notify Lender in writing of the anticipated occurrence of a Change of Control at least five days prior to the closing date of the Change of Control.

 

4. Defaults and Remedies.

4.1 Events of Default. Upon the occurrence of an Event of Default (as defined below), at the option and upon the declaration of the Lender and upon written notice to the Company, the entire unpaid principal and accrued interest on the Note shall be immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, but subject to the conversion rights set forth herein. The following events shall be considered events of default with respect to the Note (individually, an “Event of Default” and collectively, “Events of Default”):

(a) if the Company fails to pay any of the principal, interest or any other amounts payable under this Note when due and payable;

(b) if the Company files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law for the relief of, or relating to, debtors, now or hereafter in effect, or seeks the appointment of a custodian, receiver, trustee (or other similar official) of the Company or all or any substantial portion of the Company’s assets, or makes any assignment for the benefit of creditors or takes any action in furtherance of any of the foregoing, or fails to generally pay its debts as they become due; or

(c) if an involuntary petition is filed, or any proceeding or case is commenced, against the Company (unless such proceeding or case is dismissed or discharged within 60 days of the filing or commencement thereof) under any bankruptcy, reorganization, arrangement, insolvency, adjustment of debt, liquidation or moratorium statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is applied or appointed for the Company or to take possession, custody or control of any property of the Company, or an order for relief is entered against the Company in any of the foregoing.

4.2 Remedies. Upon the occurrence of an Event of Default, Lender shall have then, or at any time thereafter, all of the rights and remedies afforded creditors generally by the applicable federal laws or the laws of the State of Delaware at law, in equity or otherwise.

5. Prepayment. This Note may not be prepaid, in whole or in part, prior to the Maturity Date without the prior written consent of the Lender. If prepayment is consented to by the Lender (a) it will be without any prepayment penalties and (b) interest will no longer continue to accrue on any prepaid principal amounts after such prepayments. The Company hereby waives demand, notice, presentment, protest and notice of dishonor.

6. Payment. All payments by the Company under this Note shall be in immediately available funds at the principal office of the Company, or at such other place as Lender may from time to time designate in writing to the Company. All payments by the Company under this Note shall be made without set-off or counterclaim and be free and clear and without any deduction or withholding for any taxes or fees of any nature whatever, unless the obligation to make such deduction or withholding is imposed by law. All payments by the Company under this Note shall be applied first to the accrued interest due and payable hereunder and the remainder, if any, applied to the outstanding principal.

7. Directors, Officers and Stockholders Not Liable. Lender agrees that no stockholder, director or officer of the Company shall have any personal liability for any amounts due and payable pursuant to this Note.

8. Interest Cutoff. If a Change of Control or Qualified Financing is consummated, all interest on this Note shall be deemed to have stopped accruing as of a date selected by the Company that is up to five (5) days prior to the consummation of the Change of Control or Qualified Financing.

9. Representations, Warranties and Covenants of the Company. The Company hereby represents and warrants to the Lender as of the Issue Date that:

9.1 Organization, Good Standing, Corporate Power and Qualification. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as now conducted and as presently proposed to be conducted.

9.2 Authorization. All corporate action required to be taken by the Company’s board of directors (the “Board”) and stockholders in order to authorize the Company to enter into this Note, and to issue the Conversion Shares has been taken. All action on the part of the officers of the Company necessary for the execution and delivery of this Note, the performance of all obligations of the Company under this Note, and the issuance and delivery of the Conversion Shares has been taken. This Note, when executed and delivered by the Company, shall constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with its respective terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, or other laws of general application relating to or affecting the enforcement of creditors’ rights generally, or (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

9.3 Board Composition. The Company agrees to use best efforts to cause the Board to include, as of the Issue Date and for so long as this Note is outstanding, one (1) person designated by the Lender, who shall initially be Stephen Farr, Chief Executive Officer of the Lender. After giving effect to the preceding sentence, the Board shall be comprised of: Stephen Farr, Warren Lammert (Chairman), Jeffrey Walsh, Orrin Devinsky, Harvey Lodish, Michael Jasulavic and Daniel Fischer.

For avoidance of doubt, this Section 9.3 shall terminate and be of no further force or effect upon (i) the entry into a customary investor rights agreement, voting agreement or similar agreement by and among the Company, the Lender and the other parties thereto in connection with a Qualified Financing or (ii) any other conversion or termination of this Note.

This Note shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the State of Delaware, without regard to conflict of law principles that would result in the application of any law other than the law of the State of Delaware. Each of the parties irrevocably consents to the exclusive jurisdiction of, and venue in, the state courts in the State of Delaware (or in the event of exclusive federal jurisdiction, the courts of the State of Delaware), in connection with any matter based upon or arising out of this Note or the matters contemplated herein, and agrees that process may be served upon them in any manner authorized by the laws of the State of Delaware for such persons. Each of the parties hereto irrevocably waives, to the fullest extent permitted by law, any and all right to trial by jury in any legal proceeding (whether in contract, tort or otherwise) arising out of or related to this Note.

10.7 Delay or Omission; Waiver of Presentment. No delay or omission on the part of Lender in exercising any right under this Note shall operate as a waiver of such right or of any other right of Lender, nor shall any delay, omission or waiver on any one occasion be deemed a bar to or waiver of the same or any other right on any future occasion. The Company and every endorser or guarantor of this Note, regardless of the time, order or place of signing, hereby waives presentment, demand, protest and notices of every kind and assents to any permitted extension of the time of payment and to the addition or release of any other party primarily or secondarily liable hereunder.
