PATENT LICENSE AGREEMENT

This Patent License Agreement (this “Agreement”) is between The Trustees of the University of Pennsylvania, a Pennsylvania nonprofit corporation (“Penn”), and AAVenue Therapeutics, LLC, a Delaware limited liability company (“Company). This Agreement is being signed on October 14, 2013 (the “Execution Date”). This Agreement will become effective on October 14, 2013 (the “Effective Date”).

BACKGROUND

Penn jointly owns with Cornell University (“CU”) and University of Florida (“UFLA”) certain intellectual property developed by Drs. ▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ of Penn’s ▇▇▇▇▇▇▇▇ School of Medicine, and its School of Veterinary Medicine and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ of CU and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ of UFLA. The intellectual property is managed under an Inter-Institutional Agreement (IIA) by and among Penn, CU and UFLA (each individually, an “Institution” and collectively the “Institutions”) under which Penn has, with consultation with the other Institutions, the authority to negotiate and grant exclusive and nonexclusive licenses on behalf of the Institutions. The intellectual property relates to methods of treating diseases and conditions that may result in blindness, including, in particular, Lebers Congenital Amaurosis (LCA). The Institutions jointly own certain letters patent and/or applications for letters patent relating to the intellectual property as set forth in Exhibit A below. Company desires to obtain a co-exclusive license under the aforementioned patent rights and related intellectual property to commercially exploit the same. The Institutions have determined that the co-exclusive commercial exploitation of the patent rights and related intellectual property by Company is in the best interest of the Institutions and is consistent with their educational and research missions and goals.

In consideration of the mutual obligations contained in this Agreement, and intending to be legally bound, the parties agree as follows:

1. LICENSE

1.1 License Grant. Penn grants to Company a co-exclusive, world-wide license (the “License”) to make, have made, use, import, offer for sale and sell Licensed Products in the Field of Use during the Term (as such terms may be defined in Sections 1.2 and 6.1). The License includes the right to sublicense as permitted by this Agreement. No other rights or licenses are granted by Penn.

1.2 Related Definitions. The term “Licensed Products” means products that are made, made for, used, imported, offered for sale or sold by Company or its Affiliates or sublicensees and that would (i) in the absence of the License, infringe (or, in the case of pending patent applications, upon issuance, would infringe) at least one unexpired claim of the Patent Rights or (ii) use a process or machine covered by a claim of Patent Rights, whether the claim is issued or pending. The term “Patent Rights” means all of Penn’s, CU’s and UFLA’s patent rights represented by or

issuing from: (a) the United States patents and patent applications listed in Exhibit A; (b) any continuation, divisional and re-issue applications of (a); and (c) any foreign counterparts and extensions of (a) or (b). The term “Affiliate” means a legal entity that is controlling, controlled by or under common control with Company and that has executed either this Agreement or a written joinder agreement agreeing to be bound by all of the terms and conditions of this Agreement. For purposes of this Section 1.2, the word “control” means (x) the direct or indirect ownership of more than fifty percent (50%) of the outstanding voting securities of a legal entity, (y) the right to receive fifty percent (50%) or more of the profits or earnings of a legal entity, or (z) the right to determine the policy decisions of a legal entity. The term “Field of Use” means research, development, manufacture and commercialization for the diagnosis, treatment, amelioration and prevention of human and animal diseases. The term “co-exclusive” means that, other than the license granted to Company hereunder, during the term of this Agreement, no more than one license granted by the Institutions to no more than one third party licensee (other than rights granted to non-commercial entities for educational and research purposes pursuant to Section 1.3) under the Patent Rights will be in effect at any given time.

1.3 Reservation of Rights by Penn. Penn reserves the right for each of the Institutions to use, and to permit other non-commercial entities to use, the Patent Rights for educational and research purposes.

1.4 U.S. Government Rights. The parties acknowledge that the United States government retains rights in intellectual property funded under any grant or similar contract with a Federal agency. The License is expressly subject to all applicable United States government rights, including, but not limited to, any applicable requirement that products, which result from such intellectual property and are sold in the United States, must be substantially manufactured in the United States.

1.5 Sublicense Conditions. The Company’s right to sublicense granted by Penn under the License is subject to each of the following conditions:

(a) In each sublicense agreement, Company will (i) prohibit the sublicensee from further sublicensing under the License , provided that such prohibition shall not apply to further sublicensing by any entity that (together with its affiliates) had [**] U.S. dollars or more in worldwide drug product revenues in the calendar year most recently completed as of the grant of the sublicense; and (ii) require the sublicensee to comply with the terms and conditions of this Agreement applicable to sublicensees. For purposes of Sections 1.5 (a) and (c) and 13.5, “affiliates” shall mean a legal entity that is controlling, controlled by or under common control with sublicensee. For purposes of these Sections, the word “control” means (x) the direct or indirect ownership of more than fifty percent (50%) of the outstanding voting securities of a legal entity, (y) the right to receive fifty percent (50%) or more of the profits or earnings of a legal entity, or (z) the right to determine the policy decisions of a legal entity.

(b) Within [**] days after Company enters into a sublicense agreement, Company will deliver to Penn a complete and accurate copy of the entire sublicense agreement written in the English language. Penn’s receipt of the sublicense agreement, however, will constitute neither an approval of the sublicense nor a waiver of any right of Penn or obligation of Company under this Agreement.

(c) In the event that Company causes or experiences a Trigger Event (as defined in Section 6.4), all payments due to Company from its Affiliates or sublicensees under the sublicense agreement will, upon notice from Penn to such Affiliate or sublicensee, become payable directly to Penn for the account of Company and, subject to such notice and (except with respect to any sublicensee that is an entity that (together with its affiliates) had [**] U.S. dollars or more in worldwide drug product revenues in the calendar year most recently completed as of the grant of the sublicense, for which such consent shall not be required) the written consent of Penn, any sublicenses granted to any such Affiliate or sublicensee shall, subject to such continued payments, remain in effect. Upon receipt of any such funds, Penn will remit to Company the amount by which such payments exceed the amounts owed by Company to Penn. If Penn does not consent to survival of any sublicenses, then (except with respect to any sublicensee that is an entity that (together with its affiliates) had [**] U.S. dollars or more in worldwide drug product revenues in the calendar year most recently completed as of the grant of the sublicense, for which such consent shall not be required) they terminate along with this Agreement according to Section 6.3.

(d) Company’s execution of a sublicense agreement will not relieve Company of any of its obligations under this Agreement. Company is primarily liable to Penn for any act or omission of an Affiliate or sublicensee of Company that would be a breach of this Agreement if performed or omitted by Company, and Company will be deemed to be in breach of this Agreement as a result of such act or omission.

1.6 No License by Implication. Nothing in this Agreement confers by estoppel, implication or otherwise, any license or rights under any Penn patent other than the Patent Rights, regardless whether such patents are dominant or subordinate to the Patent Rights. Nothing in this Agreement confers by estoppel, implication or otherwise, any license or rights under any Company patent, regardless whether such patents are dominant or subordinate to the Patent Rights, or any authorization under any regulatory approval or orphan drug designation held by Company.

2. DILIGENCE

2.1 Development Plan. Company will deliver to Penn, a copy of an initial development plan for the Patent Rights (the “Development Plan”). The purpose of the Development Plan is (a) to demonstrate Company’s capability to bring the Patent Rights to commercialization, (b) to project the timeline for completing the necessary tasks, and (c) to measure Company’s progress against the projections. Thereafter, Company will deliver to Penn an annual updated Development Plan no later than [**] of each year during the Term. The Development Plan will include, at a minimum, the information listed in Exhibit B.

2.2 Company’s Efforts. Company will use commercially reasonable efforts to develop, commercialize, market and sell Licensed Products in a manner consistent with the Development Plan.

3. FEES AND ROYALTIES

3.1 Milestone Payments. In partial consideration of the License, Company will pay to Penn the applicable milestone payment listed in the table below within [**] days after achievement of each milestone event for each Licensed Product, regardless of whether such milestone was achieved by Company, its Affiliates or sublicensees. Company will provide Penn with written notice within [**] days after achieving each milestone for each Licensed Product.


MILESTONE	PAYMENT
First Commercial Sale of a Licensed Product in the US	$	2,000,000
First Commercial Sale of a Licensed Product anywhere within the European Union	$	1,750,000

The term “European Union” means the European Union as it is constituted as of the time of the relevant First Commercial Sale. For the purposes of this Section 3.1 only, the term “First Commercial Sale” shall mean the first sale by Company, its Affiliates or a sublicensee, whether at retail, wholesale or otherwise, of any Licensed Product following marketing approval in the country of sale to a third party that is not an Affiliate or a sublicensee (a “Commercial Sale”). The following are not Commercial Sales: (i) a transfer or sale by Company to a sublicensee hereunder or by a sublicensee hereunder to another such sublicensee, unless any such sublicensee is the end user of the Licensed Product, in which case such transfer shall be deemed to be a Commercial Sale; (ii) a transfer by Company, or any Affiliate or any sublicensee hereunder, to a third party for purposes of clinical trials, as free samples, or under compassionate use, patient assistance, named patient or other similar programs or studies where the Licensed Product is supplied and/or delivered without charge, or for other testing, or a commercially reasonable number of units of Licensed Product transferred for no consideration for marketing purposes (e.g., samples), but not for resale by the third party; (iii) the use of Licensed Product by Company or any of its Affiliates or sublicensees for research and development purposes; or (iv) sales made to a distributor prior to commercial launch of a Licensed Product, until the earlier of such time as Company recognizes the revenue for such transfers pursuant to US GAAP or such time as the distributor makes any sale of such Licensed Product.

For clarity, each time a milestone is achieved with respect to a Licensed Product, then any other milestone payments with respect to earlier milestones that have not yet been paid will be due and payable together with the milestone payment for the milestone that is actually achieved. For additional clarity, milestones are due and payable on Licensed Products and on products that, upon FDA approval, would become Licensed Products.

With Penn’s written concurrence and consent (upon consultation with the other Institutions), Company may substitute issuance to Penn of Company’s most recently issued preferred membership interests for up to 50% of any of the payments described above in this Section 3.1. If Company requests such option and Penn (upon consultation with the other Institutions) agrees, the membership interests issued to the Institutions would be based on the payment amount(s) that are eliminated by such issuance and the post-financing per share value of Company’s most recent preferred membership interests immediately following the closing of Company’s then-most recent equity financing. In connection with any such issuance, the Institutions will enter into a preferred share membership agreement with Company on terms and conditions substantially the same as the terms and conditions of Company’s other most recent preferred share membership agreements, and such other documents as the parties mutually agree (“Equity Document(s)”).

3.2 Earned Royalties. In partial consideration of the License, Company will pay to Penn a royalty of [**] percent ([**]%) of Net Sales in the US and [**] percent ([**]%) of Net Sales in countries outside the US during the Quarter with no minimum royalty obligations. Earned royalty payments shall be due and payable regardless of whether they are triggered by Company, its Affiliates and or its Sublicensees. Company has the right to reduce royalty payments hereunder by amounts paid to third parties for licenses to third party IP by up to [**]% on a country by country basis, if a license to third party IP is required to sell a Licensed Product. In no event shall royalties to Penn be reduced below [**]% in any country.

3.3 Related Definitions. The term “Sale” means any bona fide transaction for the sale, use, lease, transfer or other disposition of a Licensed Product to a third party for which consideration is received or expected by Company or its Affiliate or sublicensee. A Sale is deemed completed at the time that Company or its Affiliate or sublicensee invoices, ships or receives payment for a Licensed Product, whichever occurs first. The term “Quarter” means each three-month period beginning on January 1, April 1, July 1 and October 1. The term “Net Sales” means the consideration received or expected from, or the fair market value attributable to, each Sale, less Qualifying Costs that are directly attributable to a Sale, specifically identified on an invoice or other documentation and actually borne by Company or its Affiliates or sublicensees. For purposes of determining Net Sales, the words “fair market value” mean the cash consideration that Company or its Affiliates or sublicensees would realize from an unrelated buyer in an arms’ length sale of an identical item sold in the same quantity and at the time and place of the transaction. The term “Qualifying Costs” means: (a) customary trade, cash and quantity discounts and inventory management fees paid to wholesalers and distributors; (b) credits, chargebacks, retroactive price reductions, rebates, refunds or claims or returns that do not exceed the original invoice amount; (c) outbound transportation expenses and transportation insurance premiums; (d) sales and use taxes, tariffs, customs duties, excises and other taxes and fees imposed

by and indefeasibly paid to a governmental agency (other than taxes on income), (e) negotiated payments made to private sector and government third party payors (e.g., PBMs, HMOs and PPOs) and purchasers/providers (e.g., staff model HMOs, hospitals and clinics), regardless of the payment mechanism, including without limitation rebate, chargeback and credit mechanisms; and (f) discounts under discount prescription drug programs and reductions for coupon and voucher programs.

3.4 CHOP. In consideration of the terms of this Agreement, Company represents and warrants as of the Effective Date and covenants during the Term, that the Children’s Hospital of Philadelphia (“CHOP”) [**] as of the Effective Date [**]; provided that, for the avoidance of doubt, [**].

4. REPORTS AND PAYMENTS

Within [**] days after the end of each Quarter following the First Commercial Sale, Company will deliver to Penn a report, certified on behalf of the Company by the chief financial officer of Company, detailing the calculation of all royalties, fees and other payments due to Penn for such Quarter. The report will include, at a minimum, the following information for the Quarter, each listed by product, by country: (a) the number of units of Licensed Products constituting Sales; (b) the gross consideration invoiced, billed or received for Sales; (c) Qualifying Costs, listed by category of cost; (d) Net Sales; (e) the royalties, fees and other payments owed to Penn, listed by category; and (f) the computations for any applicable currency conversions. Each royalty report will be substantially in the form of the sample report attached as Exhibit C.

4.3 Records.

The records for each Quarter will be maintained for at least [**] years after submission of the applicable report required under Section 4.1.

4.4 Audit Rights. Upon reasonable prior written notice to Company, Company and its Affiliates and sublicensees will provide an independent accounting firm designated by Penn and reasonably acceptable to Company, which independent accounting firm shall be required to enter into a reasonable confidentiality agreement with Company with access to all of the books, records, key personnel and related background information required to conduct a review or audit of Sales, Net Sales, and all of the royalties, fees, and other payments payable under this Agreement. Access will be made available: (a) during normal business hours; (b) in a manner reasonably designed to facilitate such review or audit without unreasonable disruption to Company’s business; and (c) no more than [**] during the Term (as defined below) and for a period of [**] years thereafter. Penn’s independent accounting firm will disclose to Penn the discrepancies in the amounts paid by Company to Penn identified in such review or audit and such underlying books, records or

background information necessary or useful in such determination. Company will promptly pay to Penn the amount of any underpayment determined by the review or audit, plus accrued interest. If the review or audit determines that Company has underpaid any payment by [**] percent ([**]%) or more, then Company will also promptly pay the costs and expenses of Penn and its accountants in connection with the review or audit.

4.5 Information Rights. In the event that, in response to a proposal from Company, the Institutions elect to receive equity in Company as described in Section 3.1 above, then, thereafter, until the earlier of the closing of the Company’s initial public offering or such time as Penn, CU and UFLA no longer hold such equity, Company will provide to the Institutions, at least as frequently as the following reports are distributed to the Board of Directors or management of Company, copies of: (a) all Board and managerial reports that relate to the Patent Rights or the Licensed Products; and (b) all business plans, projections and financial statements for Company that are distributed to the Board of Directors or management of Company. For clarity, in the event that, in response to a proposal from Company, the Institutions elect to not receive equity in Company, then until the closing of the Company’s initial public offering, Company will provide to Perm, at least as frequently as the following reports are distributed to the Board of Directors or management of Company, copies of all Board and managerial reports that relate to the Patent Rights or the Licensed Products. After the closing of the Company’s initial public offering, Company will provide to Penn, promptly after filing, a copy of each annual report, proxy statement, 10-K, 10-Q and other material report filed with the U.S. Securities and Exchange Commission.

4.6 Currency. All dollar amounts referred to in this Agreement are expressed in United States dollars. All payments will be made in United States dollars. If Company receives payment from a third party in a currency other than United States dollars for which a royalty or fee is owed under this Agreement, then (a) the payment will be converted into United States dollars at the conversion rate for the foreign currency as published in the eastern edition of the Wall Street Journal as of the last business day of the Quarter in which the payment was received by Company, and (b) the conversion computation will be documented by Company in the applicable report delivered to Penn under Section 4.1.

5. CONFIDENTIALITY AND USE OF PENN’S NAME

5.1 Confidentiality Agreement. If Company and Penn entered into one or more Confidential Disclosure Agreements prior to the Effective Date, then such agreements will continue to govern the protection of confidential information under this Agreement, and each Affiliate and sublicensee of Company will be bound to Company’s obligations under such agreements. If, however, no Confidential Disclosure Agreement has been entered into between Company and Penn prior to the Effective Date, then in connection with the execution of this Agreement, the parties will enter into a Confidential Disclosure Agreement substantially similar to Penn’s standard form. Notwithstanding the foregoing, Penn shall be entitled to share any such Confidential Information with CU and UFLA under terms of confidentiality at least as restrictive as those set forth in the Confidentiality Agreement.

5.2 Other Confidential Matters. Penn is not obligated to accept any confidential information from Company, except for the reports required by Sections 2.1, 4.1, 4.4 and 6.6. Penn, acting through its Center for Technology Transfer and finance offices, will use reasonable efforts not to disclose to any third party outside of Penn (other than CU and UFLA) any confidential information of Company contained in those reports other than Penn’s, CU’s and UFLA’s accountants and advisors under appropriate confidentiality obligations, for so long as such information remains confidential. Each of Penn, CU and UFLA bear no institutional responsibility for maintaining the confidentiality of any other information of Company. Company may elect to enter into confidentiality agreements with individual investigators at Penn, CU or UFLA that comply with the internal policies of Penn, CU and UFLA, as applicable.

5.3 Use of Name. Company and its Affiliates, sublicensees, employees, and agents may not use the name, logo, seal, trademark, or service ▇▇▇▇ (including any adaptation of them) of Penn, CU or UFLA or any Penn, CU or UFLA school, organization, employee, student or representative, without the prior written consent of such Institution(s).

7. PATENT PROSECUTION AND MAINTENANCE

7.1 Patent Control. Penn controls the preparation, prosecution and maintenance of the Patent Rights and the selection of patent counsel, with input from Company. For purposes of this Article 7, the word “maintenance” includes any interference negotiations, claims, or proceedings, in any forum, brought by Penn, CU, UFLA, Company, a third party, or the United States Patent and Trademark Office relating to the Patent Rights, and any requests by Penn, CU, UFLA or Company that the United States Patent and Trademark Office reexamine or reissue any patent in the Patent Rights.

7.2 Payment and Reimbursement. Within [**] days after the Effective Date, Company will reimburse Penn$[**], representing approximately fifty percent (50%) of all historically accrued attorneys’ fees, expenses, official fees and all other charges accumulated prior to the Effective Date incident to the preparation, filing, prosecution and maintenance of the Patent

Rights. Company will reimburse Penn for all documented attorneys’ fees, expenses, official fees and all other charges accumulated on or after the Effective Date incident to the maintenance of U.S. Patent No. [**], within [**] days after Company’s receipt of invoices for such fees, expenses and charges. Penn will be solely responsible for all attorneys’ fees, expenses, official fees and all other charges accumulated on or after the Effective Date incident to the preparation, filing, prosecution, and maintenance of all other Patent Rights. Company will be responsible for patent expenses for U.S. Patent No. [**] under this Section 7.2 until such time as there is another co-exclusive licensee in which case Company will be responsible for 50% of ongoing patent expenses for such patent with other such co-licensee. Penn reserves the right to require the Company to provide a deposit in advance of incurring out of pocket patent expenses for U.S. Patent No. [**] estimated by counsel to exceed $[**]. If Company fails to reimburse patent expenses under this Section 7.2, or provide a requested deposit with respect to U.S. Patent No. [**], then Penn will be free at its discretion and expense to either abandon U.S. Patent No. [**] or to continue such maintenance activities, and U.S. Patent No. [**] and any continuation will be automatically excluded from the term “Patent Rights” hereunder. Penn is free at its discretion and expense to either abandon or continue the preparation, filing, prosecution, and maintenance of all Patent Rights other than U.S. Patent No. [**] at any time.

8. INFRINGEMENT

8.1 Notice. Company, Penn, CU and UFLA will notify each other promptly of any infringement of the Patent Rights that may come to their attention. Company, Penn, CU and UFLA will consult each other in a timely manner concerning any appropriate response to the infringement.

8.2 Prosecution of Infringement. During such time as Company is the sole licensee under the Patent Rights, Company may prosecute any infringement of the Patent Rights at Company’s expense, including defending against any counterclaims or cross claims brought by any party against Company, Penn, CU or UFLA regarding the Patent Rights and defending against any claim that the Patent or Patent Rights are invalid in the course of any infringement action or in a declaratory judgment action. Each of Penn, CU and UFLA reserves the right to intervene voluntarily and join Company in any such infringement litigation. If Penn, CU or UFLA chooses not to intervene voluntarily, but is a necessary party to the action brought by Company, then Company may join such Institution(s) in the infringement litigation. If Company decides not to prosecute any infringement of the Patent Rights, then any of Penn, CU or UFLA may elect to prosecute such infringement independently of Company in its or their sole discretion.

8.3 Cooperation. In any litigation under this Article 8, Company, Penn, CU or UFLA, at the request and sole expense of any other requesting party, will cooperate to the fullest extent reasonably possible. This Section 8.3 will not be construed to require any of Company, Penn, CU or UFLA to undertake any activities, including legal discovery, at the request of any third party, except as may be required by lawful process of a court of competent jurisdiction. If, however, any of Company, Penn, CU or UFLA is required to undertake any activity, including legal discovery, in any litigation or potential litigation (other than litigation or potential litigation to which Penn, CU and/or UFLA is a voluntary party) brought by, or otherwise related to, Company in accordance with this Article 8, as a right of lawful process of a court of competent jurisdiction, then, subject to Section 8.4, Company will pay all expenses incurred by Penn, CU and/or UFLA, as applicable, in

undertaking such required activities; provided that, if any such litigation or potential litigation is not brought by Company, then (a) if such litigation or potential litigation is brought by a third party licensee of Penn, CU and/or UFLA with respect to the Patent Rights, then Company shall not be required to pay such expenses incurred by Penn, CU and/or UFLA and (b) if such litigation or potential litigation is not brought by a third party licensee of Penn, CU and/or UFLA with respect to the Patent Rights, but is also otherwise related to such a third party licensee, then Company shall only be required to pay fifty percent (50%) of such expenses incurred by Penn, CU and/or UFLA.

8.4 Control of Litigation. Company may control any litigation or potential litigation involving the prosecution of infringement claims regarding the Patent Rights in which none of the Institutions is a party, including the selection of counsel, all with input from Penn, CU, and/or UFLA, as applicable, provided that Company is the sole licensee under the Patent Rights. Penn, CU, and/or UFLA, as applicable, controls any litigation or potential litigation involving the prosecution of infringement claims regarding the Patent Rights in all other instances, including where Penn, CU, and/or UFLA has elected to prosecute the infringement independently of Company or has voluntarily or involuntarily joined Company in the infringement litigation, including the selection of counsel, all with input from Company. Company must not settle or compromise any such litigation in a manner that imposes any obligations or restrictions on Penn, CU or UFLA or grants any rights to the Patent Rights, other than any permitted sublicenses, without the prior written permission of Penn, CU and/or UFLA, as applicable. In all instances in which Penn, CU and/or UFLA, as applicable, is a party, Penn, CU and/or UFLA reserve the right to select its own counsel. If Penn, CU and/or UFLA is involuntarily joined as a party, each of Penn, CU and UFLA may elect to be represented by Company’s counsel at Company’s expense if Company is a party to such litigation or potential litigation and retains the right to select its own counsel, and will be responsible for all litigation expenditures with respect to any such separate representation as set forth in Section 8.5, provided that if, in any such litigation or potential litigation brought by, or otherwise related to, Company, the interests of Penn, CU and/or UFLA, as applicable, and Company are so adverse as to prohibit counsel from jointly representing Penn, CU and/or UFLA, as applicable, and Company, the Company shall be responsible for all litigation expenditures of such separate representation(s).

8.5 Recoveries from Litigation. If Company prosecutes any infringement claims either without Penn, CU or UFLA as a party or with Penn, CU or UFLA involuntarily joined as a party, then Company will reimburse each of Penn, CU and UFLA, as applicable, for its litigation expenditures, including any attorneys’ fees, expenses, official fees and other charges incurred by such Institutions, even if there are no financial recoveries from the infringement action. Company will reimburse the Institutions within [**] days after receiving each invoice for such amounts incurred by the Institutions. After reimbursing each of Penn, CU and UFLA, as applicable, for its expenditures, Company will use the financial recoveries from such claims, if any, (a) first, to reimburse Company for its litigation expenditures; and (b) second, to retain any remainder but to treat the remainder as Net Sales for the purpose of determining the royalties due under Section 3.2. If Company prosecutes any infringement claims with Penn, CU or UFLA joined as a voluntary party, then any financial recoveries from such claims will be (x) first, shared between Company, Penn, CU and UFLA to reimburse them for their respective shares of the aggregate litigation expenditures; and (y) second, shared equally by Company, on the one hand, and Penn, CU and UFLA, on the other hand, as to any remainder after Company and each of the Institutions have fully recovered their aggregate litigation expenditures. If Penn, CU and/or UFLA, as applicable,

prosecutes any infringement claims independent of Company, then Penn, CU and/or UFLA, as applicable, will prosecute such infringement at its or their, as applicable, expense, will reimburse Company for Company’s litigation expenditures, including any attorneys’ fees, expenses, official fees and other charges to the extent incurred by Company in cooperating with Penn, CU and/or UFLA, as applicable, at its or their request, as applicable, in such prosecuting such claims, and will retain the balance of any financial recoveries in their entirety.

11.4 Other Provisions. Company will not settle or compromise any Claim pursuant to this Article 11 giving rise to Liabilities in any manner that imposes any restrictions or obligations on Penn, CU or UFLA or grants any rights to the Patent Rights or the Licensed Products, other than permitted sublicenses, without prior written consent of Penn, CU and/or UFLA, as applicable.

Best rating of “A” or better and will name Penn, CU and UFLA as an additional insured with respect to Company’s performance under this Agreement.

13.7 Severability & Reformation. If any provision of this Agreement is held to be invalid or unenforceable by a court of competent jurisdiction, then the remaining provisions of this Agreement will remain in full force and effect.
