Amended and Restated Patent License Agreement

Agreement No. PM1401501

This Amended and Restated Patent License Agreement (“Patent License Agreement”) is between the Licensor and the Licensee identified below (collectively, “Parties”, or singly, “Party”).

Background

Licensor owns or controls Patent Rights. Licensee desires to secure the right and license to use, develop, manufacture, market, and commercialize the Patent Rights. Licensor has determined that such use, development, and commercialization of the Patent Rights is in the public’s best interest and is consistent with Licensor’s educational and research missions and goals. Licensor desires to have the Patent Rights developed and used for the benefit of Licensee, the inventors, Licensor, and the public.

Licensor has previously entered into two separate license agreements with subsidiaries of Aeglea BioTherapeutics, Inc. (“Aeglea”). These license agreements are between Licensor and AECase, LLC (PM1401501), and AEMase, LLC (PM140161), respectively, both effective December 24, 2013 (the “Prior Agreements”). Licensor and Aeglea wish to amend certain terms of the Prior Agreements and to combine the two Prior Agreements into this single Amended and Restated Patent License Agreement. This Amended and Restated Patent License Agreement will amend, restate, and supersede the Prior Agreements in all respects.

NOW, THEREFORE, in consideration of the mutual covenants and premises herein contained, the Parties hereby agree as follows:

The terms and conditions of this Patent License Agreement attached hereto as Exhibit A are incorporated herein by reference in their entirety (the “Terms and Conditions”). In the event of a conflict between provisions of this Patent License Agreement and the Terms and Conditions, the provisions in this Patent License Agreement shall govern. Unless defined in this Patent License Agreement, capitalized terms used in this Patent License Agreement shall have the meanings given to them in the Terms and Conditions.

The section numbers used in the left hand column in the table below correspond to the section numbers in the Terms and Conditions.

5. Payment, Records, and Audits

5.1 Payments

All amounts referred to in the Patent License Agreement are expressed in U.S. dollars without deductions for taxes, assessments, fees, or charges of any kind. Each payment will reference the agreement number set forth at the beginning of the Patent License Agreement. All payments to Licensor will be made in U.S. dollars by check or wire transfer (Licensee to pay all wire transfer fees) payable to the payee identified in Section 18 of the Patent License Agreement and sent to the payment and reporting contact in Section 18 (Notices) of the Patent License Agreement.

5.2 Sales Outside the U.S.

If any currency conversion shall be required in connection with the calculation of payments hereunder, such conversion shall be made using the rate used by Licensee for its financial reporting purposes in accordance with Generally Accepted Accounting Principles (or foreign equivalent) or, in the absence of such rate, using the average of the buying and selling exchange rate for conversion between the foreign currency and U.S. Dollars, for current transactions as reported in The Wall Street Journal on the last business days of the Contract Quarter to which such payment pertains. Licensee may not make any tax withholdings from payments to Licensor, but Licensor agrees to supply to Licensee, upon written request, appropriate evidence from appropriate U.S. governmental agencies showing that Licensor is a resident of the United States of America for purposes of the U.S. income tax laws and is tax-exempt under such income tax laws.

5.3 Late Payments

US 4915892v.1

books, ledgers, and records relating solely to amounts payable hereunder, during regular business hours, at Licensee’s or its Affiliate’s place of business, on at least thirty (30) days advance notice, to the extent necessary to verify any payment required under the Agreement. For each Sublicensee, Licensee shall obtain such audit rights for Licensor or itself. If Licensee obtains such audit rights for itself, it will promptly conduct an audit of the Sublicensee’s records upon Licensor’s request and at Licensor’s expense, and Licensee will furnish to Licensor a copy of the findings from such audit. No more than one audit of Licensee, each Affiliate, and each Sublicensee shall be conducted under this Section 5.5 in any calendar year. If any amounts due Licensor have been underpaid, then Licensee shall immediately pay Licensor the amount of such underpayment plus accrued interest due in accordance with Section 5.3. If the amount of underpayment is equal to or greater than 5% of the total amount due for the records so examined, Licensee will pay the cost of such audit. Such audits may, if mutually agreed upon in writing by Licensor and Licensee, consist of a self-audit conducted by Licensee at Licensor’s expense and certified in writing by an authorized officer of Licensee. If the amounts due Licensor have been overpaid, the balance of overpayment shall be credited toward the next payment of monies owed Licensor. All information examined pursuant to this Section 5.5 shall be deemed to be the Confidential Information of the Licensee.

6. Patent Expenses and Prosecution

6.1 Patent Expenses

Licensee shall reimburse Licensor for all past documented, out-of-pocket expenses incurred by Licensor for filing, prosecuting, enforcing, defending and maintaining Patent Rights and related patent searches through the Effective Date of the Agreement, including those identified in Section 3.1(a) of the Patent License Agreement, and all such future expenses incurred by Licensor, for so long as, and in such countries as the Agreement remains in effect. Licensee will reimburse such patent expenses, within thirty (30) days after Licensee’s receipt of an invoice, with such payment being made either directly to Prosecution Counsel or to Licensor, as elected by Licensor in writing on or before the date of the applicable invoice. Patent expense payment delinquencies (whether owed directly to Prosecution Counsel or to Licensor) that are not in dispute in good faith will be considered a payment default under Section 7.3(a).

6.2 Direction of Prosecution

Licensor will apply for, prosecute, and maintain during the term of this Agreement, the Patent Rights in the United States and in the foreign countries listed in Schedule 6.2 hereto. Licensor will confer with Licensee to develop a strategy for the prosecution and maintenance of Patent Rights. Licensor will request that copies of all documents prepared by the Prosecution Counsel for submission to governmental patent offices be provided to Licensee for review and comment prior to filing, to the extent practicable under the circumstances.

Licensee: Aeglea BioTherapeutics, Inc.CONFIDENTIALExclusive PLA

The University of Texas at AustinPage 12Agreement No. PM1401501

US 4915892v.1

Licensee will be given reasonable opportunities to advise Licensor in the filing, prosecution, and maintenance of Patent Rights. At Licensee’s request, and reasonably in advance of any filing, fee, or other action deadlines, Licensee shall be provided with copies of all prosecution documents relating to Patent Rights so that Licensee may have the opportunity to offer comments and remarks thereon, such comments and remarks to be given due consideration by Licensor. At its discretion, Licensor may allow Licensee to instruct Prosecution Counsel directly, provided, that (a) Licensor will maintain final authority in all decisions regarding the prosecution and maintenance of the Patent Rights, (b) Licensor may revoke this authorization to instruct Prosecution Counsel directly at any time, and (c) the Prosecution Counsel remains counsel to the Licensor with an appropriate contract (and shall not jointly represent Licensee unless requested by Licensee and approved by Licensor, and an appropriate engagement letter and conflict waiver are in effect). If Licensee wishes to instruct Prosecution Counsel directly or change Prosecution Counsel, Licensee may request to do so by following the Licensor’s procedures for such. Licensor reserves in its sole discretion the ability to change Prosecution Counsel and to approve or disapprove any requested changes by Licensee. The Parties agree that they share a common legal interest to get valid enforceable patents and that Licensee will maintain as privileged all information received pursuant to this Section.

6.3 Ownership

All patent applications and patents will be in the name of Licensor (and any co-owner identified in Section 1 of the Patent License Agreement) and owned by Licensor (and such co-owner, if any). No payments due under the Patent License Agreement will be reduced solely as the result of co-ownership interests in the Patent Rights by Licensee or any other party.

6.4 Additional Foreign Filings

If Licensee wishes to pursue patent protection in countries other than the U.S., and the foreign countries listed in Schedule 6.2 hereto, then (i) Licensee shall notify Licensor in writing, subject to applicable bar dates, of such foreign countries in sufficient time to reasonably enable the preparation of such additional filings, (ii) Licensor will apply for, prosecute, and maintain during the term of this Agreement, the Patent Rights in such foreign countries, and (iii) Schedule 6.2 shall be automatically amended to include such foreign countries. If Licensee notifies Licensor in writing that it does not choose to pursue patent rights in a particular foreign country and Licensor chooses to do so, Licensor shall so notify Licensee and thereafter said patent application or patent shall no longer be included in the Patent Rights and Licensee shall have no further rights thereto.

6.5 Withdrawal from Paying Patent Costs

If at any time Licensee wishes to cease paying for any costs for a particular Patent Right or for patent prosecution in a particular jurisdiction, Licensee must give

Licensee: Aeglea BioTherapeutics, Inc.CONFIDENTIALExclusive PLA

The University of Texas at AustinPage 13Agreement No. PM1401501

US 4915892v.1

Licensor at least ninety (90) days prior written notice and Licensee will continue to be obligated to pay for the patent costs which reasonably accrue during said notice period. Thereafter, said patent application or patent shall no longer be included in the Patent Rights and Licensee shall have no further rights thereto.

6.6 U.S. Patent and Trademark Office Entity Size Status

Licensee represents that as of the Effective Date the entity size status of Licensee in accordance with the regulations of the U.S. Patent and Trademark Office is as set forth in Section 1 of the Patent License Agreement. Licensee will inform Licensor in writing on a timely basis of any change in its U.S. Patent and Trademark Office entity size status.

7. Term and Termination

7.1 Term

Unless earlier terminated as provided herein, the term of the Agreement will commence on the Effective Date and continue on a country-by-country and Licensed Product-by-Licensed Product basis, until the expiration of the Royalty Term for a particular Licensed Product in a particular country (with the entire Agreement expiring on the expiration of the last-to-expire Royalty Term).

7.2 Termination by Licensee

Licensee, at its option, may terminate the Agreement by providing Licensor written notice of intent to terminate, which such termination effective will be ninety (90) days following receipt of such notice by Licensor.

7.3 Termination by Licensor

Licensor, at its option, may immediately terminate the Agreement, or any part of Patent Rights, or any part of Field, or any part of Territory, or the exclusive nature of the license grant, upon delivery of written notice to Licensee of Licensor’s decision to terminate, if any of the following occur:

(a) Licensee becomes in arrears in any payments due under the Agreement, and Licensee fails to make the required payment within thirty (30) days after delivery of written notice from Licensor; or

(b) Licensee is in breach of any non-payment provision of the Agreement, and does not cure such breach within sixty (60) days after delivery of written notice from Licensor; or

Licensor delivers notice to Licensee of [*], even in the event that Licensee cures such breaches in the allowed period, but only if [*]; or

(d) Licensee or its Affiliate or Sublicensee participates in any proceeding or action to challenge the validity, enforceability, or scope of one or more of the Patent Rights. Provided however, this section shall not be applicable in the context of a Sublicensee or Affiliate defending against a patent infringement suit initiated by licensor, or if Licensee terminates a Sublicensee (in the event Sublicensee sues Licensor) within 30 days of receiving notice from Licensor that they are being sued by the Sublicensee.

7.4 Other Conditions of Termination

The Agreement will terminate:

(a) Immediately without the necessity of any action being taken by Licensor or Licensee, (i) if Licensee files for bankruptcy under Chapter 7 or Chapter 11 of the U.S. Bankruptcy Act or becomes insolvent, or (ii) Licensee’s Board of Directors elects to liquidate its assets or dissolve its business, or (iii) Licensee makes an assignment for the benefit of creditors or (iv) if the business or assets of Licensee are otherwise placed in the hands of a receiver, assignee for the protection of creditors or trustee, whether by voluntary act of Licensee or otherwise; or

(b) At any time by mutual written agreement between Licensee and Licensor.

7.5 Effect of Termination

If the Agreement is terminated for any reason:

(a) If a Sublicensee is in good standing under its Sublicense Agreement without any uncured defaults that would otherwise have entitled the Licensee to terminate such Sublicense Agreement, the Sublicensee may request Licensor to grant a direct license to the Sublicensee on comparable terms; which request must be in writing and received by Licensor not later than thirty (30) days after any termination of the Agreement. If Licensor determines that the Sublicensee is well qualified to continue as a direct licensee, Licensor will not unreasonably withhold consent for such request; in which event, said Sublicensee and Licensor will enter into a new mutually approved written license agreement that endeavors to preserve the essential benefits for each party that they enjoyed under the prior Agreement and Sublicense Agreement. For the avoidance of doubt, during the period between the termination of the Agreement and the date on which such a mutually approved written license agreement is consummated between the Sublicensee and Licensor, the Sublicense Agreement shall be deemed to continue with the Licensor directly. If no such mutually approved written license agreement is consummated between the Sublicensee and Licensor, the Sublicense Agreement shall be deemed to be terminated.

(c) Licensee shall tender payment of all accrued royalties and other accrued payments due to Licensor in accordance with the payment terms hereof; and

(d) Nothing in the Agreement will be construed to release either Party from any obligation that matured prior to the effective date of termination; and

(e) The provisions of Sections 8 (Confidentiality), 9 (Infringement and Litigation), 11 (Representations and Disclaimers), 12 (Limit of Liability), 13 (Indemnification), 14 (Insurance), 17 (Use of Name), 18 (Notices), and 19 (General Provisions) will survive any termination or expiration of the Agreement. In addition, the provisions of Sections 3 (Compensation), 4.1 (Quarterly Payment and Milestone Reports), 5 (Payment, Records and Audits), and 6.1 (Patent Expenses) shall survive with respect to all activities and payment obligations accruing prior to the termination or expiration of the Agreement.
