UNIVERSITY OF PENNSYLVANIA 

Amended and Restated Patent License Agreement 

This Amended and Restated Patent License Agreement (this “Agreement”) , effective March 28, 2008 (the “Restatement
Date”) is by and between The Trustees of the University of Pennsylvania, a Pennsylvania nonprofit corporation (“Penn”), and Potentia Pharmaceuticals Inc., a Delaware corporation (“Company”), and is an
amendment to and restatement of the original Patent License Agreement (the “Original Agreement”) which became effective on August 1, 2006 (the “Original Agreement Effective Date”). 

BACKGROUND 
 Penn owns certain
intellectual property developed by Dr. John Lambris of Penn’s School of Medicine relating to certain compounds that inhibit complement activation. Penn also owns (subject to the resolution of certain disputes among the University Parties
(as defined below), as described below) certain letters patent and/or applications for letters patent relating to the intellectual property. Company desires to obtain an exclusive license under the patent rights to exploit the intellectual property.
Penn has determined that the exploitation of the intellectual property by Company is in the best interest of Penn and is consistent with its educational and research missions and goals. 

Penn, Potentia, The Regents of the University of California (“California”) and Princeton University (“Princeton”) entered
into an Agreement for Resolution of Patent Inventorship Matters effective as of March 6, 2007, which agreement was amended as December 12, 2007 and March 13, 2008 (as it may be further amended from time to time, the “Patent
Inventorship Agreement”), pursuant to which the parties thereto have agreed on a process for resolving disputes among themselves concerning the inventorship of the subject matter claimed in the Patent Applications and Additional Patent
Applications (as defined in the Patent Inventorship Agreement), and ownership of any resulting patents, including without limitation certain of the Penn Patent Rights (as hereinafter defined). 

Pursuant to Section 3.3 of the Patent Inventorship Agreement, as amended, this Agreement is binding on each of California and Princeton, if such
institution is determined to have an ownership interest in the Penn Patent Rights, subject only to amendments to this Agreement that may be necessary to bring this Agreement into compliance with applicable institutional policies. 

The parties now desire to amend and restate the Original Agreement in its entirety with this Agreement to reflect various matters contemplated by the parties
as hereinafter set forth. 
 In consideration of the mutual obligations contained in this Agreement, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the parties agree as follows: 








 Execution Copy 03/28/2008 

 


	1.	LICENSE 

 1.1 License Grant. Penn grants to Company an exclusive, world-wide
license (the “License”) under the Penn Patent Rights to make, have made, use, import, offer for sale and sell Licensed Products and Other 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 incorporate technology or use a process,
product, or machine claimed in a Valid Claim of the Penn Patent Rights and are made, made for, used, imported, offered for sale or sold in a country in which such Penn Patent Rights are pending or in force, whether such manufacture, use, or sale is
by Company or by its Affiliates or sublicensees. The term “Other Licensed Products” means products that incorporate technology or use a process, product or machine claimed in a Valid Claim of the Penn Patent Rights and are made,
made for, used or sold in a country in which such Penn Patent Rights are neither pending nor in force, whether such manufacture, use or sale is by Company or by its Affiliates or sublicensees. The term “Penn Patent Rights” means all
of Penn’s patent rights represented by or issuing from: (a) the United States patents and patent applications listed in Exhibit A; (b) any continuation, divisional, non-provisional, re-examination, and re-issue applications of (a);
and (c) any foreign counterparts and extensions of (a) or (b). The term “Valid Claim” means a claim of any pending patent application or issued, unexpired patent which has not been finally cancelled, withdrawn, abandoned,
rejected, permanently revoked or nullified, held invalid or declared unpatentable or unenforceable by any court or other body of competent jurisdiction in a decision that is unappealable or unappealed within the time allowed for appeal. 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 treatment of
ophthalmic indications. For avoidance of doubt, the Field of Use includes prophylactic treatment of ophthalmic indications. 
 1.3
Reservation of Rights by Penn. Penn reserves the right to use, and to permit other non-commercial entities to use, the Penn Patent Rights for educational and research purposes only. 

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: 

  
 2 









 Execution Copy 03/28/2008 

 

 (a) In each sublicense agreement, Company will prohibit the sublicensee from further
sublicensing without the prior written consent of Penn (except for limited sublicenses granted by Company’s sublicensees to contractors or collaborators for the purpose of manufacturing, research, development or other such purpose not involving
commercial distribution of Licensed Products to third parties), and require the sublicensee to comply with the terms and conditions of this Agreement; provided that Penn shall not unreasonably withhold, delay or condition any such
consent. Notwithstanding the foregoing, if Company sublicenses to a Large Pharmaceutical Company (as defined below), Company may grant such Large Pharmaceutical Company a right to grant further sublicenses; provided that, in the case
of any such Large Pharmaceutical Company granting commercialization rights to a further sublicensee that is not an affiliate of the Large Pharmaceutical Company, the sublicense shall require that the Large Pharmaceutical Company notify Penn of the
identity of such non-affiliate further sublicensee within [**] days after the grant of such further sublicense. Further, in the event that such Company or sublicensee seeks Penn’s consent for a sublicensee to further sublicense its
commercialization rights to a downstream sublicensee or in the event a Large Pharmaceutical Company sublicensee grants such a further sublicense of commercialization rights (“sub-sublicensee”), any such downstream sublicense agreement
(“sub-sublicense”) must require the sub-sublicensee to comply with the terms of this Agreement and prohibit further sublicensing of commercialization rights. For clarity, the sub-sublicensee shall be prohibited from further sublicensing
commercialization rights, but such prohibition shall not apply to limited sublicenses granted by sub-sublicensees to contractors or collaborators for the purpose of manufacturing, research, development or other such purpose not involving commercial
distribution of Licensed Products to third parties. Finally, if Penn is requested to consent to such a sub-sublicense, the requesting party shall pay Penn’s legal expenses for review of such sublicense transaction. Except when used in this
Section 1.5a, the term sublicense includes any permitted sub-sublicense and the term sublicensee includes any permitted sub-sublicensee. “Large Pharmaceutical Company” means a company in the business of developing and commercializing
pharmaceuticals that has, together with its affiliates, a market value or, in the case of a publicly traded company, market capitalization, of at least $[**]. 

(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. Within [**] days after receipt of any such funds, Penn will remit
to Company the amount by which such payments exceed the amounts owed by Company to Penn. 
 (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 Necessary Amendments. Each party hereto shall use its reasonable efforts to enter into any such amendments to this Agreement that
may be necessary to bring this Agreement into compliance with certain institutional policies of University Parties other than Penn as may be determined, pursuant to the terms of the Patent Inventorship Agreement, to have an ownership interest in the
Penn Patent Rights. 
  

	2.	DILIGENCE 

 2.1 Development Plan. Company will deliver to Penn, within [**] days
after the Original Agreement Effective Date, a copy of an initial development plan for the Penn Patent Rights (as updated from time to time, the “Development Plan”). The purpose of the Development Plan is (a) to demonstrate
Company’s capability to bring the Penn 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. It is understood that any timelines, projections, plans, or
predictions, contained in the Development Plan and updates thereto are non-binding and will give rise to no obligations on the part of Company other than as set forth in this Agreement. 

2.2 Company’s Efforts. Company will use commercially reasonable efforts (either itself or through its Affiliates or sublicensees)
to develop, commercialize, market and sell Licensed Products and Other Licensed Products in a manner consistent with the Development Plan. 

2.3 Diligence Events. The Company will use commercially reasonable efforts (either itself or through its Affiliates or sublicensees) to
achieve each of the diligence events set forth below by the applicable completion date listed in the table below for the first Licensed Product. For purposes of this Section 2.3 and Section 3.4 below, the diligence or milestone event, as
the case may be, associated with the initiation of a Phase II clinical trial for a Licensed Product shall be deemed achieved upon the initiation of any Phase II portion of a Phase I trial for such Licensed Product.

	3.	FEES AND ROYALTIES 

 3.1 License Initiation Fee. In partial consideration of the
License, Company will pay to Penn on the Original Agreement Effective Date a non-refundable, non-creditable license initiation fee of $[**], of which $[**] received in the Option Agreement between Potentia Pharmaceuticals, Inc. and the University of
Pennsylvania dated December 8, 2005 is fully creditable. 
 3.2 Equity Issuance. In partial consideration for the License,
Company will issue to Penn on or about the Original Agreement Effective Date, [**] shares of common stock of the Company. In connection with this Agreement, Penn will execute and accede to the provisions of a Stockholders Agreement between Company
and Penn (“Stockholders Agreement”), the terms of which shall be reasonably acceptable to Penn and substantially similar to and consistent with those applicable terms set forth in the Third Amended and Restated Stockholders Agreement,
dated as of April, 2008 and attached hereto as Exhibit C, by and between the Company and its stockholders, the terms of which shall apply to all shares of capital stock of the Company currently issued to or held by Penn. 

3.3 License Maintenance Fees. In partial consideration of the License, Company will pay to Penn, on or within [**] days of each
anniversary of the Original Agreement Effective Date, until the first Sale (as defined in Section 3.6) of the first Licensed Product, the applicable license maintenance fee listed in the table below.

 3.4 Milestone Payments. 

(a) In partial consideration of the License, Company will pay to Penn the applicable milestone payment listed in the table below after the
first achievement of each milestone event for each Licensed Product. Company will provide Penn with written notice within [**] days after achieving each milestone.

 Execution Copy 03/28/2008 

 

 
of a Milestone Event with respect to a Licensed Product triggers all prior milestones with respect to such Licensed Product unless previously triggered and paid. 

(b) Notwithstanding anything in Section 3.4(a) to the contrary, if development of a Licensed Product for a particular indication in the
Field of Use ceases (a “Failed Product”), and development of a next Licensed Product for the same indication (“Follow-On Product”) subsequently commences or continues, then any of the Milestone Payments previously made by Company
in connection with such Failed Product shall be fully creditable against the repeated achievement of such milestone event by such Follow-On Product to achieve such milestone event. In the event that Company files an IND before December 31,
2006, the Milestone Payment for Receipt of IND Approval will be waived by Penn. In the event that Company files an IND after December 31, 2006, but before July 1, 2007, the payment Milestone Payment for Receipt of IND Approval will be
reduced to $[**]. In addition, any License Maintenance Fee paid within the same year that one or more Milestone Payments are due will be creditable toward any applicable Milestone Payment payable with respect to any Licensed Product in the Field of
Use within a year after the date on which such License Maintenance Fee payment was due. 
 (c) The Milestone Payments set forth in this
Section 3.4 shall be payable upon achievement of the corresponding milestone event by Company or any of its Affiliates or sublicensees; provided that any such Milestone Payments payable based upon achievement of the corresponding milestone
event by a third party sublicensee shall be subtracted from Sublicense Income for purposes of determining the Sublicense Fees payable to Penn pursuant to Section 3.8. 

3.5 Earned Royalties. In partial consideration of the License, Company will pay to Penn a royalty of [**] percent ([**]%) of Net Sales
of Licensed Products during the Quarter. In partial consideration of the License, and in recognition of know-how conveyed by Penn to Company, Company will pay to Penn a royalty of [**] percent ([**]%) of Net Sales of Other Licensed Products during
the Quarter. The royalty percentage due on Net Sales of Licensed Products or Other Licensed Products is full pass-through and is not subject to reduction in any event, without the written consent of Penn. 

3.6 Related Definitions. The term “Sale” means any bona fide transaction for which consideration is received or
expected by Company or its Affiliate or sublicensee for the sale, use, lease, transfer or other disposition of a Licensed Product or Other Licensed Product, as the case may be, to a third party, but excluding any sales for test marketing,
pre-clinical or clinical studies, compassionate use, or disposition of samples in customary quantities. A Sale is deemed completed at the time that Company or its Affiliate or sublicensee receives payment for a Licensed Product or Other Licensed
Product. 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, in the case of consideration other than cash, the fair market value attributable to, such non-cash consideration, 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” means 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 on a non-duplicative basis, actual costs and expenses incurred net
of any refunds

 Execution Copy 03/28/2008 

 

 
or offsets specific to Licensed Products: (a) trade cash and quantity discounts (e.g. discounts, for prompt or timely payment), (b) inventory management fees paid to wholesalers and
distributors, not to exceed [**]% of Net Sales; (c) credits, chargebacks, retroactive price reductions, rebates, refunds or returns that do not exceed the original invoice amount; (d) outbound transportation and insurance expenses;
(e) sales and use taxes, tariffs, customs duties, excises and other taxes and fees imposed by, and indefeasibly paid to, a governmental agency on the sale, transportation or delivery of Licensed Product or Other Licensed Product (other than
taxes on income); (f) 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; (g) discounts under discount prescription drug programs and reductions for coupon and voucher programs; and (h) Bad debts calculated in accordance with GAAP
consistently applied (any reductions to bad debts previously deducted from Net Sales will become an add back to Net Sales in the quarter when reduction in bad debt is recognized). In the event that the Licensed Product is Sold in combination with
one or more other active ingredients (as such, a “Combination Product”), Net Sales from such Combination Product, for the purpose of determining royalty payments hereunder, shall be determined by multiplying the Net Sales of the
Combination Product during the applicable royalty reporting period, by the fraction, A/A+B, where A is [**] the Licensed Product when sold separately in finished form, and B is [**] other active ingredients included in the Combination Product when
sold separately in finished form, in each case during the applicable royalty reporting period or, if sales of both the Licensed Product and the other active ingredients did not occur in such period, then in the most recent royalty reporting period
in which sales of both occurred. In the event that such [**] be determined for both the Licensed Product and the other active ingredients included in the Combination Product, Net Sales for purposes of determining royalty payments hereunder shall be
calculated by multiplying Net Sales of the Combination Product by the fraction of C/C+D, where C is [**] Licensed Product and D is [**] all other active ingredients included in the Combination Product. In such event, Company shall in good faith make
a determination of the [**] of the Licensed Product and the other active ingredients included in the Combination Product, and shall notify Penn in writing, of such determination and provide Penn with the data supporting such determination. Penn
shall have the right to review such determination and supporting data, and to notify Company if Penn disagrees with such determination within [**] days of Company’s notification to Penn in writing thereof (provided, that, if no notice is given
by Penn within such [**]day period, Penn shall be deemed to have accepted Company’s determination of such respective fair market values hereunder). If Penn notifies Company of its disagreement within such [**]day period, then such matter shall
be submitted for resolution pursuant to Section 13.10. 
 3.7 Minimum Royalties. In partial consideration of the License,
Company will pay to Penn the amount, if any, that the applicable minimum royalty listed in the table below exceeds Company’s actual earned royalties under Section 3.5 for each Quarter after the first Sale of a Licensed Product.

 3.8 Sublicense Fees. Subject to Section 3.3(c), in partial consideration of the License,
Company will pay to Penn, within [**] days after the end of each Quarter following the Original Agreement Effective Date, a sublicense fee of [**] percent ([**]%) of all Sublicense Income (as hereinafter defined) received by Company and its
Affiliates during such Quarter from any non-Affiliate sublicensee for a sublicense under the Penn Patent Rights. “Sublicense Income” means all cash payments plus the fair market value of all other consideration of any kind, received
by Company and its Affiliates from non-Affiliate sublicensees for sublicenses granted under the License by Company and its Affiliates, other than (i) royalties paid to Company or any Affiliate by such a sublicensee based upon Sales or Net Sales
by such sublicensee (and, in sublicensing arrangements in which a profit-sharing structure is used to compensate Company or Affiliate, other than profit-sharing amounts paid to Company or Affiliate), (ii) payments made to Company or any
Affiliate in consideration for the issuance of equity or debt securities of Company or such Affiliate, provided, that if an equity or debt investment is made in Company or such Affiliate in connection with such a sublicense agreement, any premium
paid over the fair market value for such equity or debt securities will be treated as Sublicense Income hereunder; (iii) amounts paid to Company or any Affiliate to fund the research and/or development of Licensed Products and/or Other Licensed
Products; (iv) reimbursement of expenses relating to prosecution, maintenance and/or defense of Penn Patent Rights under which such sublicenses are granted; and (v) amounts paid to Company or any Affiliate, on a per detail fee, full-time
equivalent funding or other fee-for-service basis that reasonably represents the value of such services, for conducting detailing activities with respect to Licensed Products and/or Other Licensed Products under a co-promotion or similar arrangement
with such sublicensee.  
  

	4.	REPORTS AND PAYMENTS 

 4.1 Royalty Reports. Within [**] days after the end of each
Quarter following the first Sale, Company will deliver to Penn a report, certified 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 or Other Licensed Products, as the case may be, constituting Sales; (b) the gross consideration

attached as Exhibit D. 
 4.2 Payments. Company will pay all royalties, fees and other payments due to Penn under Sections 3.4, 3.5,

 4.3 Records.
Company will maintain, and will cause its Affiliates and sublicensees to maintain, complete and accurate books, records and related background information to verify

 Execution Copy 03/28/2008 

 

 
Sales, Net Sales, and all of the royalties, fees, and other payments due or paid under this Agreement, as well as the various computations reported under Section 4.1. 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 independent certified public accountants reasonably acceptable to Company with access to all of the books, records and
related background information required by Section 4.3 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 Penn’s 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. 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. Until the closing of the Company’s initial public offering, Company will provide to Penn, at least as frequently as the following reports are distributed to the Board of Directors of Company, copies of: (a) all
reports to the board that relate to the Penn Patent Rights or the Licensed Products or the Other Licensed Products, as the case may be; and (b) such portions of all business plans, projections and financial statements for Company that are
distributed to the Board of Directors of Company that relate to the Penn Patent Rights or the Licensed Products or the Other Licensed Products, as the case may be; provided that Penn’s right to receive such reports, business plans, projections
and financial statements shall not include the right to attend Board meetings or to receive materials with respect to which Company reasonably determines must be excluded to preserve attorney-client privilege or with respect to which Penn has a
conflict of interest related to the parties’ respective rights and obligations under this Agreement. It is understood that as an owner of equity in Company, Penn shall also receive all reports and other information provided by Company to other
owners of a like amount of equity in Company. 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. 

4.7 Place of Payment. All payments by Company are payable to “The Trustees of the University of Pennsylvania” and will be

	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 Restatement 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 Restatement 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. The term “Confidentiality Agreement” means all Confidential Disclosure Agreements
between the parties that remain in effect after the Restatement Date. 
 5.2 Other Confidential Matters. Penn is not obligated to
accept any confidential information from Company, except for the delivery of information and/or reports required by Sections 1.5, 2.1, 4.1, 4.4, 4.5 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 any confidential information of Company contained in those reports, for so long as such information remains confidential. Without limiting the parties’ respective rights and
obligations under any separate Confidentiality Agreement between the parties, Penn bears 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 that comply with Penn’s internal policies. 
 5.3 Use of Penn’s Name.
Company and its Affiliates, sublicensees, employees, and agents may not use the name, logo, seal, trademark, or service mark (including any adaptation of them) of Penn or any Penn school, organization, employee, student or representative, without
the prior written consent of Penn. Company and its Affiliates, sublicensees, vendors, and manufacturers shall have the right to mark the Licensed Products and/or packaging thereof with relevant patent numbers. 

 

	6.	TERM AND TERMINATION 

 6.1 Term. This Agreement will commence on the Original
Agreement Effective Date and terminate, on a product-by-product and country-by-country basis upon the later of: (a) the expiration of the last Valid Claim to expire of the Penn Patent Rights; or (b) ten (10) years after the first Sale
of the first Licensed Product or Other Licensed Product, as the case may be, in a 

  
 10 









 Execution Copy 03/28/2008 

 

 
country if no Valid Claim of Penn Patent Rights covering the applicable Licensed Product or Other Licensed Product is pending or remains in force in such country (as the case may be, the
“Term”). 
 6.2 Early Termination by Company. Company may terminate this Agreement at any time effective upon
completion of each of the following conditions: (a) providing at least sixty (60) days prior written notice to Penn of such intention to terminate; (b) ceasing to make, have made, use, import, offer for sale and sell all Licensed
Products and Other Licensed Products except to the extent permitted under Section 6.6; (c) causing all Affiliates to cease making, having made, using, importing, offering for sale and selling all Licensed Products and Other Licensed
Products, except to the extent permitted under Section 6.6; and (d) paying all amounts owed to Penn under this Agreement through the effective date of termination. 

6.3 Early Termination by Penn. Penn may terminate this Agreement if: (a) Company is more than [**] days late in paying to Penn any
amounts owed under this Agreement and does not pay Penn in full, including accrued interest, within [**] days after written demand from Penn therefor (a “Payment Default”), provided that (i) if Company in good faith disputes
any payment amount allegedly due under a provision of this Agreement other than Section 3.5, Company may pay the disputed amount to Penn under protest and, upon final resolution of the dispute, Penn shall refund any amounts so paid that are
determined not to have been payable to Company, with interest at the rate set forth in Section 4.8 and (ii) if Company or a sublicensee of Company in good faith disputes any payment amount allegedly due under Section 3.5 or the amount
of Net Sales made by Company or a sublicensee of Company upon which such royalty obligation is based, Penn may not terminate this Agreement unless Company fails to pay any such disputed amount finally determined to have been payable to Penn, with
interest at the rate set forth in Section 4.8, within [**] days after final resolution of the dispute; provided further that, in the event that a good faith dispute regarding a payment amount allegedly due under
Section 3.5 arises because a sublicensee of Company disputes Net Sales amounts that Company contends were made by the sublicensee, Company shall use good faith efforts to resolve such dispute and shall keep Penn reasonably informed regarding
the status of such dispute; (b) except for a Payment Default, Company or its Affiliate or sublicensee materially breaches this Agreement and does not cure the breach within [**] days after written notice of the breach; or (c) Company or
its sublicensee experiences a Trigger Event and, in the case of a sublicensee Company has not terminated the license to such sublicensee prior to or automatically upon the occurrence of the Trigger Event. For purposes of Sections 6.3 and 6.4, the
terms “sublicensee” excludes (i) manufacturers not authorized to sell or commercially distribute Licensed Products or Other Licensed Products to third parties and (ii) contractors, service providers, and collaborators whose
rights are limited to making, having made, and/or using Licensed Products or Other Licensed Products for research and/or development purposes.

assignment for the benefit of creditors, or (vi) suffers proceedings being instituted against it under any law related to bankruptcy, insolvency, liquidation or the reorganization,
readjustment or release of debtors and, if contested by it, not dismissed or stayed within [**] days; (c) the institution or commencement by Company or its Affiliate or sublicensee of any proceeding under any law related to bankruptcy,
insolvency, liquidation or the reorganization, readjustment or release of debtors; (d) the entering of any order for relief relating to any of the proceedings described in Section 6.4 (b) or (c) above; (e) the calling by
Company or its Affiliate or sublicensee of a meeting of its creditors with a view to arranging a composition or adjustment of its debts; (f) the act or failure to act by Company or its Affiliate or sublicensee indicating its consent to,

if any, after an opportunity of at least [**] days to cure such failure after written notice thereof, or (h) the commencement by Company of any action against Penn, including an action for declaratory judgment, to declare or render invalid or
unenforceable the Patent Rights, or any claim thereof; provided that the foregoing clauses (a) , (b), (c), (d), (e), and (f) shall not apply with respect to Company or its Affiliates if Company has sublicensed all or substantially all of
its rights hereunder to one or more Large Pharmaceutical Company(-ies) and such Large Pharmaceutical Company(-ies) remain in material compliance with the terms and conditions of its or their sublicense(s) relating to this Agreement and the foregoing
clauses (a) , (b), (c), (d), (e), and (f) shall not apply with respect to a sublicensee or acquirer of Company that is a Large Pharmaceutical Company that seeks protection under applicable bankruptcy laws for the purpose of reorganizing
and continuing to operate if such sublicensee or acquirer of Company remains in material compliance with the terms and conditions of its sublicense relating to this Agreement. 

6.5 Effect of Termination. Upon the termination of this Agreement for any reason except as a result of the expiration of the Term:
(a) the License terminates; (b) Company and all its Affiliates will cease all making, having made, using, importing, offering for sale and selling all Licensed Products or Other Licensed Products, as the case may be, except to extent
permitted by Section 6.6; (c) Company will pay to Penn all amounts, including accrued interest, owed to Penn under this Agreement through the date of termination; (d) Company will, at Penn’s request, return to Penn all
confidential information of Penn and provide to Penn one complete copy of all data with respect to Licensed Products and Other Licensed Products as the case may be generated by Company during the Term in the course of its performance of this
Agreement that will facilitate the further development of the technology licensed under this Agreement; and (e) except as otherwise provided in this Agreement in the case of termination under Section 6.3, all duties of Penn and all rights
(but not duties) of Company under this Agreement immediately terminate without further action required by either Penn or Company. Notwithstanding the foregoing, in the event of any termination of this Agreement by Penn under Section 6.3 (Early
Termination by Penn), each sublicense of the Penn Patent Rights shall survive such termination and remain in full force and effect in accordance with its terms and shall be assigned to and assumed by Penn, provided, that (x) the sublicensee is
not then in material breach of the terms and conditions of its sublicense or the applicable terms of this Agreement, (y) the sublicensee agrees in writing to remain in material compliance with all terms and conditions of the sublicense, and
(z) Penn shall not be required to assume the obligations of the Company under such sublicense other than the grant of the sublicense itself and other obligations under this Agreement which are passed-through to such sublicensee under such
sublicense. At Company’s 

  
 12 









 Execution Copy 03/28/2008 

 

 
request, Penn shall enter into a “stand-by” license agreement directly with the applicable sublicensee on terms reasonably acceptable to Penn, to confirm the rights of the sublicensee
set forth in this Section 6.5. 
 6.6 Inventory & Sell Off. Upon the termination of this Agreement for any reason,
Company will cause physical inventories to be taken immediately of: all completed Licensed Products or Other Licensed Products as the case may be, including Licensed Products and Other Licensed Products that have been formulated into final finished
form (“Pre-Termination Formulated Product”), and are under the control of Company or its Affiliates or sublicensees (except for sublicensees whose sublicense agreements remain in effect following such termination pursuant to
Section 6.5 (“Surviving Sublicensees”). Company will deliver promptly to Penn a copy of the written inventory, certified by an officer of the Company. Upon termination of this Agreement for any reason, Company will promptly
remove, efface or destroy all references to Penn from any advertising, labels, web sites or other materials used in the promotion of the business of Company or its Affiliates or sublicensees (except Surviving Sublicensees), and Company and its
Affiliates and sublicensees (except Surviving Sublicensees) will not represent in any manner that it has rights in or to the Penn Patent Rights or the Licensed Products or Other Licensed Products as the case may be, provided however, that inventory
on hand may be marked with appropriate patent numbers. Upon the termination of this Agreement as a result of expiration of the Term, Company and its Affiliates and sublicensees may continue to sell Licensed Products and Other Licensed Products;
provided that royalties on Net Sales of Pre-Termination Formulated Product sold after such termination shall continue to be payable notwithstanding such termination. Upon any termination of this Agreement other than as a result of expiration of the
Term and other than pursuant to Section 6.3(a) or (c), Company and its Affiliates and sublicensees (except Surviving Sublicensees) may sell off its inventory of Licensed Products, and/or Other Licensed Products as the case may be, existing on
the date of termination for a period of [**] months and pay Penn royalties on Net Sales of such inventory within [**] days following the expiration of such [**] month period. 

6.7 Survival. Company’s obligation to pay all amounts, including accrued interest, owed to Penn under this Agreement will survive
the termination of this Agreement for any reason. Sections 1.5(c), 6.1, 6.5, 6.6, 6.7, 13.9, 13.10 and 13.11 and Articles 4, 5, 9, 10, and 11 will survive the termination of this Agreement for any reason in accordance with their respective terms.
Company’s right to continue to prosecute and/or participate in litigation instituted pursuant to Section 8, and Company’s right to recover the proceeds of patent litigation instituted pursuant to Section 8 shall also survive
termination of this Agreement for any reason, provided that such infringement actions are instituted by Company while the License is in effect. It is understood that Company’s right to continue to prosecute and/or participate in patent
litigation and to recover the proceeds thereof following termination of this Agreement are based on infringement occurring while the License is in effect and do not entitle Company to share in financial recoveries based on acts of infringement that
may occur following termination of this Agreement. 
  

	7.	PATENT MAINTENANCE AND REIMBURSEMENT 

 7.1 Patent Maintenance. Penn controls the
preparation, prosecution and maintenance of the Penn Patent Rights and the selection of patent counsel, with input from Company. If, 

  
 13 









 Execution Copy 03/28/2008 

 

 
however, Company desires to manage the preparation, prosecution and maintenance of the Patent Rights with input from Penn, and with agreement from Penn, which will not be unreasonably withheld,
and Company is the sole licensee to the Penn Patent Rights, then Company and Penn will enter into with patent counsel a Patent Management Agreement in the form attached as Exhibit E. Penn will consider Company’s reasonable request to select
alternate patent counsel. For clarity, for so long as there is more than one licensee to Penn Patent Rights, Penn does not typically agree to a Patent Management Agreement but may consider doing so if all licensees to the Penn Patent Rights agree
thereto. 
 7.2 Patent Reimbursement. Within [**] days after the Original Agreement Effective Date, Company will reimburse Penn for
all historically accrued attorneys fees, expenses, official fees and all other charges accumulated prior to the Original Agreement Effective Date incident to the preparation, filing, prosecution and maintenance of the Penn Patent Rights, including
any interference negotiations, claims or proceedings. Hereafter, subject to section 7.3, Company will either pay directly under the Patent Management Agreement or reimburse Penn for the following percentage of all documented attorneys fees,
expenses, official fees and all other charges accumulated on or after the Restatement Date incident to the preparation, filing, prosecution, and maintenance of the Penn Patent Rights, including any interference negotiations, claims or proceedings,
within [**] days after Company’s receipt of invoices for such fees, expenses and charges, provided however, that for so long as there is more than one licensee to the Penn Patent Rights, Company’s reimbursement of ongoing patent expenses
will be reduced by the percentage of such expenses assumed by such other licensee(s). At the time of the Restatement Date, the parties expect that there will be another licensee and that Company’s reimbursement obligation will be reduced to
[**] percent ([**]%) of such expense. Penn will provide Company with prompt written notice of any reduction and will negotiate in good faith to apportion the reimbursement obligation equitably among licensees. 

7.3 Other Matters. Except during the pendency of a Patent Management Agreement: (1) Penn will use reasonable efforts to copy, and
will instruct patent counsel to copy, Company on all patent prosecution and patent maintenance matters related to the Penn Patent Rights including all correspondence from and to patent offices and all drafts of proposed filings with patent offices;
(2) Penn will use reasonable efforts to and will instruct patent counsel to notify Company in writing at least [**] days prior to the due date or deadline for any action which could adversely affect the pending status of any patent application
within the Penn Patent Rights, the maintenance of any granted patent within the Penn Patent Rights, Penn’s right to file any continuing application or foreign counterpart application based on the Penn Patent Rights, or the breadth of any claim
within the Penn Patent Rights; (3) Company has the right to consult with Penn, and Penn will give due consideration to Company’s comments; and (4) Penn will request Company’s written consent prior to taking any of the following
actions: (i) provoking or participating in interference or opposition proceedings; (ii) filing national stage applications or continuation applications in any country other than the United States. Should Company refuse to consent to such
actions, Penn may proceed with any such actions at Penn’s expense and thereafter, the patents, patent rights or patent applications obtained, maintained or secured through such actions will be excluded from the Penn Patent Rights, provided that
patents, patent rights or patent applications will not be excluded from Penn Patent Rights to the extent they are obtained through the filing of national stage applications without Company’s consent, in countries other than Australia, Canada,
Europe, Japan and the United States. For clarity, 

  
 14 









 Execution Copy 03/28/2008 

 

 
Company shall not be required to pay attorney’s fees, expenses, official fees or other charges, or reimburse Penn therefor, in connection with any of the actions listed in (4)(i) or
(ii), including in connection with subsequent prosecution and maintenance of national stage applications listed in 4(ii), if such action(s) was/were undertaken without Company’s prior written consent. 

 

	8.	INFRINGEMENT 

 8.1 Notice. Company and Penn will notify each other promptly of any
infringement of the Penn Patent Rights by a product in the Field of Use (“Field Infringement”) that may come to their attention. Company and Penn will consult each other in a timely manner concerning any appropriate response to the Field
Infringement. 
 8.2 Enforcement. Company may enforce the Penn Patent Rights against any Field Infringement at Company’s
expense. Company shall not, and shall require its Affiliates and sublicensees not to, settle or compromise any such litigation in a manner that imposes any obligations or restrictions on Penn without Penn’s prior written permission. Financial
recoveries from any such litigation will be: (a) first, applied to reimburse Company and/or its Affiliates and/or sublicensees and to reimburse Penn for its or their Litigation Expenditures; and (b) second, as to any remainder, (i) if
such litigation is brought by Company and/or its Affiliates, [**] percent ([**]%) shall be paid to Company and/or its Affiliates and [**] percent ([**]%) shall be paid to Penn or (ii) if such litigation is brought by a non-Affiliate
sublicensee, [**] of any amount paid to Company and/or its Affiliates under the applicable sublicense agreement shall be retained by Company and or its Affiliates and [**] of any amount paid to Company and/or its Affiliates under the applicable
sublicense agreement shall be paid to Penn. For purposes of this Agreement, “Litigation Expenditures” shall be defined as: any attorneys’ fees or costs, whether incurred directly or indirectly, in reference to a pertinent litigation
or investigation, including but not limited to, court costs, local counsel fees, deposition costs, subpoena costs, court reporter costs, expert fees, and other reasonable expenses directly incurred for investigation or litigation of claims. 

8.3 Intervention and Involuntary Participation. 

(a) Voluntary Intervention. Penn reserves the right to voluntarily intervene and join Company in any litigation under Section 8.2. 

(b) Involuntary Participation. If Penn is required to participate involuntarily in any litigation referred to under Section 8.2, (such
as, for example, but not limited to, being joined or named as a defendant, necessary party, involuntary plaintiff, or indispensable party), then: (i) Company may seek to join Penn involuntarily and (ii) if Penn cannot be joined
involuntarily, then Company may join Penn in any litigation referred to under Section 8.2 if Penn’s participation is required for standing to bring or maintain the lawsuit in which Company seeks to join Penn, and Penn will not object to
being joined in said litigation; provided however, that in any instance described in this Section 8.3(b), Company will reimburse Penn’s Litigation Expenditures on an ongoing basis, within [**] days of submission of actual invoices.

 8.4 Penn Prosecution. If Company does not prosecute any infringement of the Patent Rights, then Penn may elect to prosecute such
infringement at Penn’s expense. If Penn elects to 

  
 15 









 Execution Copy 03/28/2008 

 

 
prosecute such infringement, then any financial recoveries will retained by Penn in their entirety; provided, however, that if Company, its Affiliates, or sublicensees is/are involuntarily joined
in any litigation referred to in this Section 8.4, any financial recoveries will first be applied to reimburse any Litigation Expenditures incurred by Company, its Affiliates and sublicensees. If Company, its Affiliates, or sublicensees
participates in any litigation referred to in this Section 8.4 at Penn’s request, Penn will reimburse any Litigation Expenditures incurred by Company, its Affiliates and sublicensees on an ongoing basis, within [**] days of submission of
actual invoices. 
 8.5 Cooperation. In any litigation under this Article 8, either party, at the request and expense of the other
party, will cooperate to the extent reasonable and reasonably possible. This Section 8.5 will not be construed to require either party 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. Notwithstanding anything else herein, if Company or its Affiliates sublicenses any or all rights under the License to, or is acquired by, a Large Pharmaceutical Company, such Large
Pharmaceutical Company shall not be required to cooperate under this section 8.5 if such Large Pharmaceutical Company reasonably deems that doing so would present unacceptable business or legal risks.

PRODUCTS, OTHER LICENSED PRODUCTS AND ANY OTHER TECHNOLOGY LICENSED UNDER THIS AGREEMENT ARE PROVIDED ON AN “AS IS” BASIS. PENN MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY OF

	10.	LIMITATION OF LIABILITY 

 10.1 Limitation of Liability. PENN WILL NOT BE LIABLE TO
COMPANY, ITS AFFILIATES, SUBLICENSEES, SUCCESSORS OR ASSIGNS, OR ANY THIRD PARTY WITH RESPECT TO ANY CLAIM: ARISING FROM COMPANY’S USE OF THE PENN PATENT RIGHTS, LICENSED PRODUCTS, OTHER LICENSED PRODUCTS OR ANY OTHER TECHNOLOGY LICENSED UNDER

	11.	INDEMNIFICATION

term “Liabilities” means all damages, awards, deficiencies, settlement amounts, defaults, assessments, fines, dues, penalties, costs, fees, liabilities, obligations, taxes, liens, losses, lost profits and expenses (including, but
not limited to, court costs, interest and reasonable fees of attorneys, accountants and other experts) that are incurred by an Indemnified Party or awarded or otherwise required to be paid to third parties by an Indemnified Party. The term
“Indemnification Event” means any Claim against one or more Indemnified Parties arising out of or resulting from: (a) the development, testing, use, manufacture, promotion, sale or other disposition of any Penn Patent Rights or
Licensed Products or Other Licensed Products as the case may be by Company, its Affiliates, its sublicensees, its assignees or its vendors, including, but not limited to, (x) a product liability or other Claim of any kind related to use by a

 11.2 Other Provisions. Company will not settle or compromise any Claim

aware and will cooperate with Company’s reasonable requests in connection with defense of such Claim, at Company’s expense. If Company fails or declines to assume the defense of any Claim within [**] days after notice of the Claim, then
Penn may assume the defense of such Claim for the account and at the risk of Company, and any Liabilities related to such Claim will be conclusively deemed a liability of Company. The indemnification rights of the Indemnified Parties under this
Article 11 are in addition to all other rights that an Indemnified Party may have at law, in equity or otherwise. 
  

	12.	INSURANCE 

 12.1 Coverages. Company (either itself or through its Affiliates or
sublicensees) will procure and maintain insurance policies for the following coverages with respect to personal injury, bodily injury and property damage arising out of Company’s performance under this Agreement or under the applicable
sublicense agreement; provided that, if insurance coverage obligations are met through Affiliates or sublicensees, then any such Affiliate or sublicense must directly indemnify Penn to the full extent of Company’s indemnification hereunder and,
further provided that any such insurance, whether procured and maintained by Company or through an Affiliate or sublicensee, must name Penn as an additional insured and Company, its Affiliate and/or sublicensee, as applicable, shall provide Penn

per occurrence and in the aggregate; and (c) prior to the Sale of the first Licensed Product, product liability coverage, in a minimum amount of $[**] combined single limit per occurrence
and in the aggregate. Penn may review periodically the adequacy of the minimum amounts of insurance for each coverage required by this Section 12.1, and Penn reserves the right to require Company to adjust the limits accordingly, consistent
with industry standards for comparable products, markets, insured parties and indemnified claims. The required minimum amounts of insurance do not constitute a limitation on Company’s liability or indemnification obligations to Penn under this
Agreement. Notwithstanding the foregoing, if Company and/or any Affiliate sublicenses the Penn Patent Rights to a Large Pharmaceutical Company or Company is acquired by a Large Pharmaceutical Company, such sublicensee or acquirer may satisfy the
insurance criteria set forth under Section 12.1 (a), (b) and (c) through reasonable self-insurance.

foreign countries without prior approval of the agency. Penn does not represent that no license is required, or that, if required, the license will issue. 

13.4 Modification, Waiver & Remedies. This Agreement may only be modified by a written amendment that is executed by an

or this Agreement during the Term. Any prohibited assignment or security interest will be null and void. 
 13.6 Notices. Any notice

PREEMPTIVE RIGHTS 
 2.1
Generally. Subject to Sections 2.7 and 2.8 below, the Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, any Preferred Stock or any other equity securities of the
Company having rights, preferences and privileges senior to those of the Common Stock, (collectively, unless excluded by Section 2.7 below, the “Offered Securities”), unless in each such case the Company shall have first
complied with this Agreement. The Company shall deliver to each Preferred Stockholder a written notice of any proposed or intended issuance, sale or exchange of Offered Securities (the “Offer”), which Offer shall (i) identify
and describe the Offered Securities, (ii) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (iii) identify the
persons or entities to which or with which the Offered Securities are to be offered, issued, sold or exchanged (the “Offerees”), and (iv) offer to issue and sell to or exchange with each Preferred Stockholder (A) such
portion of the Offered Securities as the aggregate number of shares of Common Stock into which all shares of Preferred Stock held by such Preferred Stockholder are convertible bears to the total number of shares of Common Stock into which all shares
of Preferred Stock held by the Preferred Stockholders are then convertible (the “Available Amount”). Each Preferred Stockholder shall have the right, for a period of fifteen (15) days following delivery of the Offer, to
purchase or acquire, at the price and upon the other terms specified in the Offer, the number of Offered Securities described above. The Offer by its terms shall remain open and irrevocable for such 15-day period. 

2.2 Acceptance. To accept an Offer, in whole or in part, a Preferred Stockholder must deliver a written notice (the “Notice of
Acceptance”) to the Company prior to the end of the 15-day period of the Offer, setting forth with respect to such Preferred Stockholder, the portion of such Preferred Stockholder’s Available Amount that the Preferred Stockholder
elects to purchase. A Preferred Stockholder may designate, at any time prior to actual purchase, any Affiliate of such Preferred Stockholder as the entity entitled to purchase all or a portion of such Preferred Stockholder’s Available Amount,
provided that (i) such designee agrees to be bound by the terms of this Agreement in the same capacity as the Preferred Stockholder hereunder and (ii) the purchase of such Offered Securities by such designee does not violate the
registration requirements of or require registration under the Securities Act or any applicable state securities laws. 
 2.3 Sale by
Company. In the event that Notices of Acceptance are not given by Preferred Stockholders in respect of all the Offered Securities, the Company shall have up to 120 days from the expiration of the period set forth in Section 2.1 above to
issue, sell or exchange all or any part of such Offered Securities as to which Notices of Acceptance have not been given by the Preferred Stockholders (the “Refused Securities”), but only to one or more of the Offerees and only upon
terms and conditions (including, without limitation, unit prices and interest rates) which are not more favorable, in the aggregate, to the acquiring person or persons or less favorable to the Company than those set forth in the Offer. 

  
 C-4 








 2.4 Decrease in Shares Sold. In the event the Company shall propose to sell less than all
the Refused Securities (any such sale to be in the manner and on the terms specified in Section 2.3 above), then each Preferred Stockholder may, at its sole option and in its sole discretion by delivery of notice to the Company within ten
(10) days of receipt of notice of such reduction, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the
Preferred Stockholder elected to purchase pursuant to Section 2.2 above multiplied by a fraction, (i) the numerator of which shall be the reduced number or amount of Offered Securities the Company proposes to issue, sell or exchange
(including Offered Securities to be issued or sold to Preferred Stockholders pursuant to Section 2.2 above prior to such reduction) and (ii) the denominator of which shall be the amount of all Offered Securities. In the event that any
Preferred Stockholder so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until
such securities have again been offered to the Preferred Stockholders in accordance with Section 2.1 above. 
 2.5 Purchase
of Shares. Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, or if there are no Refused Securities, on a date mutually agreeable to the Company and the Preferred Stockholders who have delivered
Notices of Acceptances with respect to at least a majority of the Offered Securities. Section 2.2 above, the Preferred Stockholders shall acquire from the Company, and the Company shall issue to the Preferred Stockholders, the number or amount
of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 2.4 above if the Preferred Stockholders have so elected, upon the terms and conditions specified in the Offer. The purchase by the Preferred
Stockholders of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and each Preferred Stockholder of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and
substance to the Offerees and Preferred Stockholders who will purchase at least a majority of such Offered Securities. 
 2.6
Shares Not Sold. Any Offered Securities not acquired by the Preferred Stockholders or the Offerees in accordance with Section 2.3 above may not be issued, sold or exchanged until they are again offered to the Preferred Stockholders in
accordance with Section 2.1 above.  
 2.7 Exclusions from First Refusal Right. The rights of the Preferred Stockholders
under Sections 2.1 through 2.6, inclusive, shall not apply to the following securities and such securities (“Excluded Securities”), shall not be deemed “Offered Securities”: 

(a) Common Stock issued as a stock dividend to holders of Common Stock or upon any subdivision of shares of Common Stock; 

(b) Preferred Stock issued as a stock dividend to holders of Preferred Stock or upon any subdivision of shares of Preferred Stock; 

  
 C-5 








 (c) the issuance of shares of Common Stock, or options exercisable therefor, including
options outstanding on the date of this Agreement, issued or issuable to current or former employees, officers or directors of, or consultants or advisers to, the Company pursuant to stock purchase or stock option plans or similar arrangements
approved by the Board of Directors; 
 (d) securities issued or issuable in connection with a bona fide non-equity financing
transaction (e.g. equipment financing arrangements and bank lines of credit) that is approved by the Board of Directors; 
 (e)
securities issued solely in consideration for the acquisition (whether by merger or otherwise) by the Company or any of its Subsidiaries of all or substantially all of the stock or assets of any other entity in a transaction that is approved by the
Board of Directors; 
 (f) shares of Common Stock issued in a Qualifying Financing; 

(g) securities issued to a strategic partner in connection with a development, collaboration or other similar agreement that is approved
by the Board of Directors; or 
 (h) securities issued, sold or exchanged by the Company as to which the Requisite Majority has
elected to designate as Excluded Securities. 
 2.8 Applicability of this Agreement to Offered Securities. All Offered Securities
issued, sold or exchanged pursuant to this Agreement as applicable, shall be subject to the terms of this Agreement unless otherwise determined by the Requisite Majority. 

ARTICLE 3 
 RESTRICTIONS
ON TRANSFER 
 3.1 Generally. Any Transfer of any of the Shares by a Stockholder, other than according to the terms of this
Agreement, shall be void and transfer no right, title or interest in or to any such Shares to the purported transferee. Moreover, unless approved by the Board of Directors, no Transfers shall be valid unless and until the transferee shall have
executed and delivered a counterpart of this Agreement. 
 3.2 Permitted Transfers. A Stockholder may Transfer without
compliance with Sections 3.3 through 3.5 of this Agreement, any or all of his Shares to an Affiliate of such Stockholder, to his spouse or children or to a trust established for the benefit of his spouse, children or himself, or dispose of them
under his will or pursuant to a judicial decree or order (provided that, in each such case, the Company receives written notice of such Transfer and, prior to the completion of such Transfer, each such transferee (a “Permitted
Transferee”) or his or her legal representative shall have executed documents assuming the obligations of the transferring Stockholder under this Agreement with respect to the transferred Shares). Notwithstanding the foregoing, in the event
of any Transfer pursuant to this Section 3.2 the 

  
 C-6 








 
transferor and the Permitted Transferee(s) shall be jointly and severally liable as one Stockholder pursuant to this Agreement. The pledge of any Shares by a Stockholder shall be permitted only
with the approval of the Board of Directors, in its sole discretion. 
 3.3 Offer for Sale; Notice of Proposed Sale. If any
Stockholder (the “Transferring Party”) desires to Transfer any of his Shares in any transaction other than pursuant to Section 3.2 of this Agreement, such Transferring Party shall first deliver written notice of such desire to
do so (the “Notice”) to the Company. The Notice shall specify: (i) the name and address of the party to which the Transferring Party proposes to Transfer the Shares (the “Offeror”), (ii) the number of
Shares the Transferring Party proposes to Transfer (the “Shares Proposed for Transfer”), (iii) the consideration per Share offered by the Offeror to the Transferring Party for the proposed Transfer, and (iv) all other
material terms and conditions of the proposed transaction. The Notice shall be accompanied by a copy of the offer from the Offeror to the Transferring Party or such other evidence of the offer that is reasonably satisfactory to the Company.

 3.4 Option to Purchase. 

(a) The Company shall have the option (the “Option”) to purchase all but not less than all of the Shares Proposed for
Transfer for the consideration per Share and on the terms and conditions specified in the Notice. The Option must be exercised no later than thirty (30) days after such Notice has been delivered (the “Option Period”). Such
option shall be exercised by delivery of written notice to the Secretary of the Company. 
 (b) In the event the Company duly
exercises its option to purchase the Shares Proposed for Transfer, the closing of such purchase shall take place at the offices of the Company on a single date agreed to between the Transferring Party and the Company, which date shall be not later
than sixty (60) days after the expiration of the Option Period. 
 (c) To the extent that the consideration proposed to be paid
by the Offeror for the Shares Proposed for Transfer consists of property other than cash or a promissory note, the consideration required to be paid by the Company upon exercise of the Option may consist of cash equal to the value of such property,
as determined in good faith by agreement of the Transferring Party and the Company. In the event that the parties are not able to determine the value of such property, the value of such property shall be determined by a panel of three appraisers
whose decision shall be final and binding on the parties hereto. The Transferring Party shall choose one appraiser; the Company shall choose the second appraiser; and the two so selected shall select and designate a third appraiser. The value of the
property shall be equal to the average of the values determined by the three appraisers. The fees and expenses of all such appraisers shall be borne equally by the Transferring Party and by the Company. 

  
 C-7 








 3.5 Sale to Offeror; Closing. If the Company does not exercise the Option within the
Option Period, then the option of the Company to purchase such Shares Proposed for Transfer, whether exercised or not, shall terminate and, subject to the provisions in Section 3.1, the Transferring Party may sell, on the terms and conditions
set forth in the Notice, the Shares Proposed for Transfer to the Offeror, provided that (a) the transaction contemplated by the Notice shall be consummated not later than ninety (90) days after the expiration of the Option Period and
(b) the Offeror agrees to be bound by the terms of this Agreement in the same capacity as the Transferring Party. 
 ARTICLE 4

 CO-SALE 
 4.1
Co-Sale Rights. Upon the proposed occurrence of a Co-Sale Transaction, any one or more of the Stockholders may demand that the effectiveness of the Co-Sale Transaction be conditioned upon the right of each such Stockholder to sell to the Person
acquiring Shares in the Co-Sale Transaction (the “Co-Sale Purchaser”) all or any part of such Stockholder’s Shares (a “Co-Sale”), provided that such Stockholder (an “Electing Co-Sale
Stockholder”) delivers written notice to the Stockholders transferring Shares in the Co-Sale Transaction (the “Transferring Co-Sale Stockholders”) to the Co-Sale Purchaser of such demand stating the number of Shares he so
wishes to sell within forty-five (45) days after having received notice from the Transferring Co-Sale Stockholders that a proposed sale of Shares would constitute a Co-Sale Transaction. The price for such Stockholders’ Shares shall be
equal to the per Share price to be paid in the Co-Sale Transaction; provided, however, that the proceeds from the Co-Sale Transaction shall be reallocated among such Electing Co-Sale Stockholders and the Transferring Co-Sale Stockholders such that
such Electing Co-Sale Stockholders and the Transferring Stockholders shall be entitled to receive such portion of the proceeds as if the proceeds had been distributed by the Company in complete liquidation pursuant to the rights and preferences set
forth in the Certificate of Incorporation (the “Certificate”) of the Company as in effect immediately prior to the entry into the first agreement entered into in connection with, and prior to, such Co-Sale Transaction (giving effect
to applicable orders of priority). The closing of the Co-Sale shall take place concurrently with the sale by the Transferring Co-Sale Stockholders to the Co-Sale Purchaser. If the Co-Sale Purchaser is unwilling or unable to purchase all of the
Shares such Stockholders desire to sell, neither the Company nor any Stockholders shall enter into the Co-Sale Transaction. 
 4.2
Treatment of Sale Proceeds. The proceeds of any sale made by any Transferring Co-Sale Stockholders without compliance with the provisions of Section 4.1 shall be deemed to be held in constructive trust in such amount as would have been due
to the Stockholders desiring to sell Shares if the Transferring Co-Sale Stockholders had complied with this Agreement. 

  
 C-8 








 ARTICLE 5 

DRAG-ALONG OBLIGATIONS 

5.1 Generally. 

(a) If requested by the holders of a majority of the outstanding Shares (the Stockholders constituting such majority are hereinafter
referred to as the “Drag-Along Stockholders”), each of the other Stockholders (the “Participating Sellers”) hereby agrees to sell all of his Shares to any other Person (the “Proposed Buyer”) in the
manner and on the terms set forth in this Article 5 in connection with the sale by the Drag-Along Stockholders to the Proposed Buyer of all of the Shares held by the Drag-Along Stockholders (a “Drag-Along Transaction”). 

(b) The obligations of the Stockholders pursuant to this Section 5.1 are subject to the satisfaction of the following conditions:

 (i) upon the consummation of a Drag-Along Transaction, each of the Stockholders shall receive the same proportion of the aggregate
consideration from such Drag-Along Transaction that such Stockholder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Certificate
as in effect immediately prior to the entry into the first agreement entered into in connection with, and prior to, such Drag-Along Transaction (giving effect to applicable orders of priority); 

(ii) subject to Section 5.3(b), if any Stockholders are given an option as to the form of consideration to be received, each other
Stockholder shall be given the same option; 
 (iii) the Drag-Along Transaction must be a bona fide, arms’ length transaction;

 (iv) the Proposed Buyer must not be affiliated with any of the Drag-Along Stockholders, including without limitation, that the
Proposed Buyer must not, directly or indirectly, be a shareholder, officer, director, partner, member or manager of any of the Drag-Along Stockholders, and the Proposed Buyer must not, directly or indirectly, control, be controlled by, or be under
common control with, any of the Drag-Along Stockholders; 
 (v) if any Drag-Along Stockholder obtains in connection with the
Drag-Along Transaction any contractual rights, such as registration rights, rights of co-sale, preemptive rights, and the like, each Participating Seller shall receive substantially commensurate contractual rights in connection with such Drag-Along
Transaction; 

  
 C-9 








 (vi) no options, warrants or similar rights to acquire equity in the Proposed Buyer (or
its parent) in the Drag-Along Transaction may be granted, issued or sold to any Drag-Along Stockholder unless granted, or issued to each Participating Seller on a pro rata basis (except for options granted to Drag-Along Stockholders who are
employees of the Company), based on the proportion of outstanding Shares held by each Stockholder as of immediately prior to the consummation of the Drag-Along Transaction; 

(vii) no Participating Seller shall be obligated to make any out-of-pocket expenditure prior to the consummation of the Drag-Along
Transaction and no Participating Seller shall be obliged to pay more than such Participating Seller’s pro rata share (based upon the amount of consideration received) of reasonable expenses incurred in connection with a consummated Drag-Along
Transaction to the extent such costs are incurred for the benefit of all Stockholders and are not otherwise paid by the Company or the Proposed Buyer (costs incurred by or on behalf of a Stockholder for such Stockholder’s sole benefit will not
be considered costs of the transaction hereunder), provided that a Stockholder’s liability for such expenses shall be limited to the total purchase price received by such Stockholder in such Drag-Along Transaction for such Stockholder’s
Shares; 
 (viii) in the event that the Stockholders are required to provide indemnification of the Proposed Buyer in connection with
the Drag-Along Transaction, each Stockholder shall not be liable for more than such Stockholder’s pro rata share (based upon the amount of consideration received) of any indemnification liability and such liability shall not exceed the total
purchase price or consideration received by such Stockholder for such Stockholder’s Shares in such Drag-Along Transaction; and 

(ix) each Stockholder shall only be obligated to make representations or warranties in any such Drag-Along Transaction as to such
Stockholder’s (A) title and ownership of the Shares to be sold by such Stockholder, (B) authorization, execution and delivery of relevant documents by such Stockholder, and (C) the enforceability of relevant documents against
such Stockholder. 
 5.2 Notice. A “Drag-Along Notice” shall be delivered by a Stockholder who is a part of the
Drag-Along Stockholders on behalf of all such Stockholders to the Participating Sellers. The Drag-Along Notice shall set forth the principal terms of the proposed Drag-Along Transaction insofar as it relates to the Shares, the purchase price, the
name and address of the Proposed Buyer and the other principal terms of the proposed Drag-Along Transaction. 
 5.3
Closing. 

  
 C-10 








 (a) If the Drag-Along Stockholders consummate the Drag-Along Transaction, the
Participating Sellers shall be bound and obligated to sell all of their Shares in the Drag-Along Transaction on the same terms and conditions (except as otherwise contemplated by Section 5.1(b)(i) and Section 5.3(b)) as the Drag-Along
Stockholders sell their Shares. Subject to Section 5.1, the Stockholders agree that they will also take such actions and execute such documents and instruments as shall be necessary or desirable in order to consummate the Drag-Along Transaction
expeditiously. If at the end of the one hundred eightieth (180th) day following the date of the Drag-Along Notice the Drag-Along Transaction has not been completed other than by reason of any failure of a Participating Seller to comply with its
obligations under this Article 5, the Participating Sellers shall be released from their obligations under the Drag-Along Notice, the Drag-Along Notice shall be null and void, and it shall be necessary for a separate Drag-Along Notice to have been
furnished and the terms and provisions of this Article 5 separately complied with, in order to consummate a Drag-Along Transaction pursuant to this Article 5. 

(b) Notwithstanding any other provision of this Agreement, in the event the consideration to be paid in exchange for Shares in the
proposed Drag-Along Transaction includes any securities and the receipt thereof by a Participating Seller which would require under applicable law (i) the registration or qualification of such securities or of any person as a broker or dealer
or agent with respect to such securities or (ii) the provision to any participant in the Drag-Along Transaction of any information other than such information as would be required under Regulation D promulgated under the Securities Act in an

 FIRST AMENDMENT TO 

AMENDED AND RESTATED PATENT LICENSE AGREEMENT 

This First Amendment to the Amended and Restated Patent License Agreement (this “Amendment”) is dated as of October 14, 2009,
by and between The Trustees of the University of Pennsylvania, a Pennsylvania nonprofit corporation (“Penn”), and Potentia Pharmaceuticals, Inc., a Delaware corporation (“Company”). Capitalized terms used but not otherwise
defined herein shall have the meanings ascribed to such terms in the Amended and Restated Patent License Agreement (the “Agreement”) entered into as of March 28, 2008 (the “Agreement Effective Date”), by and between Penn and
Company, and references herein to Sections shall refer to Sections of the Agreement. 
 WHEREAS, under the Agreement, Penn has licensed to
Company rights to develop and commercialize Licensed Products and Other Licensed Products in the Ophthalmic Field; 
 WHEREAS, Company and
Alcon Research Ltd. (“Alcon”) intend to enter into a license agreement in which rights to develop and commercialize Licensed Products and Other Licensed Products in the Ophthalmic Field are granted to Alcon (the “Alcon License”);

 WHEREAS, Penn has determined that, pursuant to the terms set forth in this Amendment, providing Company and Alcon with additional
flexibility regarding the development and commercialization of Licensed Products and Other Licensed Products in the Ophthalmic Field is in the best interest of Penn and is consistent with its educational and research missions and goals; 

NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the parties hereto,
intending to be legally bound, hereby agree as follows: 
 1. Company acknowledges and agrees that the Technology Access Fee that Company expects to receive
from Alcon as a result of the execution of the Alcon License will be Sublicense Income under the Agreement. 
 2. Penn agrees that Alcon shall be deemed a
Large Pharmaceutical Company for purposes of the Agreement. 
 3. The table set forth in Section 2.3 is hereby amended and restated in its entirety to
read as follows: 
  

			
	 DILIGENCE EVENT
	  	COMPLETION DATE
	Filing of IND for the Licensed Product	  	July 1, 2007

	[**]	  	[**]

 4. Penn agrees that the study described in Exhibit A hereto shall qualify as a Phase II clinical trial for
purposes of the tables set forth in Sections 2.3 and 3.4. 
 5. Penn agrees that, in the event that no Valid Claim for Development Purposes (as defined
below) exists on January 1, 2014 in an issued United States patent that covers the manufacture, use, offer for sale, sale or importation of a Licensed Product then under development, the completion date for the Initiation of a Phase III
Clinical Trial for the Licensed Product diligence event set forth in Section 2.3 shall be extended until the earlier of (a) the date that is three (3) months after the issuance of such a Valid Claim of a United States patent or
(b) January 1, 2015, and any delay in initiating Phase III Clinical Trials that is wholly or partially attributable to the non-existence of such Valid Claim shall not constitute a breach of Company’s obligations under Sections 2.2 or
2.3. For purposes of the preceding sentence, “Valid Claim for Development Purposes” shall mean a claim: (i) in any issued, unexpired Penn Patent Right which has not been donated to the public, revoked nor held unenforceable or invalid
by a governmental agency or court of competent jurisdiction by a decision from which there is no appeal or (if there is a right to appeal) from which the period for appeal has expired without such appeal, and that has not been disclaimed or admitted
to be invalid, or unenforceable through reissue, disclaimer or otherwise, or (ii) in any United States or foreign patent application among the Penn Patent Rights, which shall not have been finally cancelled, withdrawn or abandoned by any
administrative agency or other body of competent jurisdiction; provided that, on a Licensed Product-by-Licensed Product and country-by-country basis, a pending patent application shall be deemed to have been abandoned if, as of the date that is [**]
years subsequent to the earliest filing date from which such application claims priority, no other Valid Claim that covers the manufacture, use, offer for sale, sale or importation of such Licensed Product has issued as a patent in such country (the
“Constructive Abandonment Date”), and the claims of such application shall no longer constitute Valid Claims with respect to such Licensed Product in such country as of such Constructive Abandonment Date. 

6. In lieu of the definitions of “Net Sales”, “Qualifying Costs” and “Combination Product” set forth in Section 3.6, solely
for purposes of calculating royalties payable by Company to Penn pursuant to Section 3.5 as a consequence of sales by Alcon, its affiliates and permitted licensees of Licensed Products and Other Licensed Products pursuant to the Alcon License,
“Net Sales” shall mean the gross invoiced price for Licensed Products and Other Licensed Products sold by Alcon, its affiliates or permitted sublicensees (the “Selling Party”) to third parties, less Qualifying Costs.
“Qualifying Costs” shall mean the following deductions from such gross amounts: (i) normal and customary trade, cash and other quantity discounts, rebates and allowances actually allowed and taken; (ii) credits or allowances
actually granted to the customer for damaged goods, returns, recalls, rebates or rejections of Licensed Products and Other Licensed Products; (iii) sales, use, excise, ad valorem or any other sales-related taxes (to the extent borne by Selling
Party and separately stated on the invoice and included in the computation of gross sales); (iv) chargebacks related to sales of Licensed Products and Other Licensed Products, to the extent actually allowed and taken by a third party;
(v) freight, insurance and other transportation and handling fees to the extent included in the invoice price; and (vi) compulsory payments and rebates directly related to the sale of Licensed Products and Other Licensed Products, accrued,
paid, or deducted pursuant to federal or state government regulations. Generally, only items that are deducted from Selling Party’s gross sales of Licensed Product(s) and Other Licensed Product(s), as included in Selling Party’s published
financial 

  
 - 3 - 








 
statements and that are in accordance with GAAP, applied on a consistent basis, shall be considered Qualifying Costs and shall be deducted from such gross sales for purposes of the calculation of
Net Sales. However, compulsory payments required by federal or state governments based upon sales volume or market share of Licensed Products (but for clarity excluding taxes on the Selling Party’s net income), to the extent borne by the
Selling Party, shall be deducted from “Net Sales” regardless of its classification in the Selling Party’s published financial statements; provided that any such deduction shall be limited to that share of such compulsory payment
proportional to the share of the total sales volume or market share of the Selling Party used to compute the compulsory payment represented by applicable Net Sales of Licensed Products; and provided further that, Company shall include in each report
provided to Penn pursuant to Section 4.1 for any Quarter in which such deduction is taken an explanation of how the share of such compulsory payment allocated to applicable Net Sales of Licensed Products was calculated. A Qualifying Cost may be
deducted only once regardless of the number of categories that describe such amount. In the event that a Selling Party makes any adjustment to such deductions after the associated Net Sales have been reported pursuant to Section 4.1, the
adjustments and payment of any royalties due shall be reported with the next quarterly report. Sales between or among Alcon, its affiliates and sublicensees shall be excluded from the computation of Net Sales if such sales are not intended for end
use, but Net Sales shall include the subsequent final sales to third parties by Alcon or any such affiliates or sublicensees. A Licensed Product or Other Licensed Product shall not be deemed to be sold if it is provided free of charge to a third
party in reasonable quantities as a sample consistent with industry standard promotional and sample practices. 
 If Alcon or its affiliates or any
permitted sublicensee sells a Licensed Product or Other Licensed Product in combination with one or more other therapeutically or prophylactically active ingredients (whether combined in a single formulation or package, as applicable, or formulated
separately but packaged under a single label approved by a regulatory authority and sold together for a single price in a manner consistent with the terms of this Agreement) (a “Combination Product”), Net Sales of such Combination Product
for the purpose of determining the payments due to Penn pursuant to the Agreement will be calculated by multiplying actual Net Sales of such Combination Product as determined pursuant to the preceding paragraph by the fraction A/(A+B) where A is
[**] such Licensed Product or Other Licensed Product on a worldwide basis, if sold separately, and B is [**] the other active ingredient(s) in the combination on a worldwide basis, if sold separately. In the event it is not possible to determine the
fraction A/(A+B) based on the criteria specified in the preceding sentence (e.g., if the Licensed Product or Other Licensed Product component is not sold separately), Net Sales for the purpose of determining royalties due to Penn pursuant to the
Agreement for the Combination Product shall be D/(D+E) where D is [**] the portion of the Combination Product that contains the Licensed Product or Other Licensed Product and E is [**] the portion of the Combination Product containing the other
active ingredient(s) included in such Combination Product, with such fair market values determined by mutual agreement of Penn, Alcon and Company, provided that after any acquisition of Company by Alcon, the Company shall be represented by a
representative of the Company’s stockholders immediately prior to such acquisition. 
 In the event that Alcon or its affiliates or any of its
permitted sublicensees bundle the Licensed Product(s) or Other Licensed Product(s) with other products or services being purchased from the Selling Party and the Selling Party discounts the sales price of the Licensed Product(s) or

Other Licensed Product(s) to customers as a loss leader, or Licensed Product(s) or Other Licensed Product(s) are otherwise provided to customers without a specific sale price, then, in such case,
the Net Sales for such Licensed Product(s) or Other Licensed Product(s) to such customers shall be deemed to equal the average sales price for which such Licensed Product(s) or Other Licensed Product(s) themselves have been sold over the immediately
preceding [**] months, and if no such sales have occurred, the arm’s length price that third parties would generally pay for the Licensed Product(s) or Other Licensed Product(s) alone when not purchasing any other product or service from the
Selling Party. 
 7. Penn agrees that the [**] day period for Company to provide the report set forth in Section 4.1 shall be extended to [**] days
with respect to sales of Licensed Products and Other Licensed Products by Alcon, its affiliates and permitted sublicensees pursuant to the Alcon License. 

8. Penn agrees that the [**] day periods for payments set forth in Sections 3.4(a) and 4.2 shall be extended to [**] days with respect to any obligations for
Company to make payments to Penn under the Agreement that arise from the development and commercialization of Licensed Products and Other Licensed Products by Alcon, its affiliates or permitted sublicensees under the Alcon License. 

9. Effectiveness of Amendment. This Amendment will take effect upon the execution of the Alcon License by both Alcon and Company (the “Amendment
Effective Date”), written notice of which Company shall promptly provide to Penn. 
 10. Miscellaneous. The parties hereby confirm and agree
that, as amended hereby, the Agreement remains in full force and effect and is a binding obligation of the parties hereto. This Amendment may be executed in counterparts, each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument. 
 IN WITNESS WHEREOF, the parties have caused this Amendment to be executed by their duly
authorized representatives.
