V.), a Bermudan limited partnership (“Gelesis-Bermuda” and collectively with Gelesis-US, “Gelesis”).

WHEREAS, PureTech is required to provide certain funding, management services and intellectual property as set forth in (i) the Note Purchase Agreement dated on or about the date hereof by and between Gelesis-US and PureTech and (ii) the Management and Overhead Services Agreement dated on or about the date hereof by and between Gelesis-US and PureTech;

WHEREAS, PureTech will receive certain consideration for such funding, management services and intellectual property, including the potential royalty payments and sublicense payments set forth herein;

NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

1. Definitions. Reference is made to that certain Patent License and Assignment Agreement dated December 9, 2009 (the “License Agreement”) by and among Gelesis-Bermuda, One S. R. L., ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the License Agreement.

2. Royalties.

(a) Gelesis shall pay to PureTech, during the applicable term described in Section 2(b) below, earned royalties at the following rates:

If the manufacture, use, lease, or sale of any Licensed Product is covered by more than one of the Valid Claims under the Patent Rights in the Field, or any patents in the Improvements or Food IP, multiple royalties shall not be due.

(b) The Parties hereby agree that should intellectual property rights owned by a third party pose as an obstacle to the development or commercialization of any Licensed Product that is not a Food Product (the “Blocking IP”), Gelesis-Bermuda or an applicable affiliate of Gelesis-Bermuda shall, after consulting in good faith with PureTech, seek a potential settlement solution with the Blocking IP holder and the royalty rates for Licensed Products that are not Food Products set forth in Section 2(a) shall be reduced by the amount of such consideration paid for the rights to such Blocking IP; provided, however that in no case shall the royalty rates for Licensed Products that are not Food Products set forth in Section 2(a) be reduced by more than fifty percent (50%) as a result of the application of this Section 2(b).

(c) The obligation of Gelesis to pay royalties pursuant to Section 2(a) shall terminate on a country-by-country basis concurrently with (i) the expiration or termination of the applicable Valid Claim under the Patent Rights in the country in which the Licensed Product is sold, or (ii) the withdrawal, cancellation, or disclaiming of the applicable Valid Claim under the Patent Rights in the country in which the Licensed Product is sold.

3. Sublicense Income. Gelesis shall pay to PureTech ten percent (10%) of Sublicense Income received by Gelesis and its affiliates on Food Products.

4. Reports and Payments. Following the commencement of Gelesis’s obligations to pay any royalties pursuant to Section 2, Gelesis shall deliver to PureTech within sixty (60) days after the end of each calendar quarter a written report showing its computation of royalties due under this Agreement for such calendar quarter. Simultaneously with the delivery of each such report, Gelesis shall tender payment of all amounts shown to be due thereon. The royalty payments due on sales in currencies other than U.S. dollars shall be calculated using the appropriate exchange rate for such currency quoted by the relevant Government Authority as published by the Wall Street Journal on the last business day of the calendar quarter to which such report relates. All amounts due under this Agreement shall be paid to PureTech in U.S. dollars by wire transfer to an account in a bank designated by PureTech, or in such other form and/or manner as PureTech may reasonably request. During the term of this Agreement, PureTech, at its cost, shall have the right from time to time (not to exceed once during each calendar year) to engage a certified public accountant, reasonably acceptable to Gelesis, to inspect, during normal business hours, upon reasonable advance notice (not less than one week), and subject to a written obligation of confidentiality acceptable to Gelesis, such books, records and other supporting data of Gelesis as may be necessary to verify Gelesis’s computation of royalties due under this Agreement.

5. Withholding Taxes. All payments made by Gelesis to PureTech shall be net of withholding taxes.

6. Miscellaneous.

(a) Transfers of Rights under this Agreement. This Agreement, and the rights and obligations of each party hereunder, may not be assigned by any party without the prior written consent of each of PureTech and Gelesis.

(d) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware and the laws of the United States applicable therein (without giving effect to any choice or conflict of laws provision or rule that would cause the application of the laws of any other jurisdiction) and shall be treated in all respects as a Delaware contract.

No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

(i) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

(j) Severability. If any provision of this Agreement shall be held to be illegal, invalid or unenforceable, such illegality, invalidity or unenforceability shall attach only to such provision and shall not in any manner affect or render illegal, invalid or unenforceable any other provision of this Agreement, and this Agreement shall be carried out as if any such illegal, invalid or unenforceable provision were not contained herein.

(k) Non-Impairment.

AMENDMENT NO. 1 TO ROYALTY AND SUBLICENSE INCOME AGREEMENT

This Amendment No. 1 (“Amendment No. 1”) to the Royalty and Sublicense Income Agreement dated as of December 18, 2009 (the “Agreement”) by and among Gelesis, Inc, a Delaware corporation (“Gelesis-US”), Gelesis IP L. P., a Bermudan limited partnership (“Gelesis-Bermuda”), and PureTech Ventures, LLC, a Delaware limited liability company (“PureTech”), is entered into on this 28th day of June, 2012 by and among Gelesis-US, Gelesis-Bermuda, PureTech, and Gelesis, LLC, a Delaware limited liability company (“Gelesis. LLC”). This Amendment No. 1 shall not become binding and shall have no effect unless and until Gelesis, Inc. enters into a License and Collaboration Agreement (the “Gelesis/AZ Agreement”) with AstraZeneca AB (“AstraZeneca”) substantially in the form attached hereto as Exhibit A. The date on which the Gelesis/AZ Agreement is signed shall be the effective date (the “Amendment No. 1 Effective Date”) of this Amendment No. 1. For purposes hereof, all capitalized terms used herein but not defined herein shall have the meanings given to them in the Master Agreement and License Agreement.

Pursuant to Section 6(e) of the Agreement and Section 9. 9 of the License Agreement, Gelesis-US, Gelesis-Bermuda, Gelesis, LLC, and PureTech hereby agree as follows:

1. The parties hereby agree that Gelesis-US and Gelesis-Bermuda hereby assign to Gelesis, LLC, and Gelesis, LLC hereby accepts and assumes, all rights, interests, and obligations under this Agreement. All references to “Gelesis-US”, “Gelesis-Bemuda”, and “Gelesis” in the Agreement shall hereafter be deemed to refer to Gelesis, LLC.

2. Section 2 of the License Agreement is hereby deleted and replaced its their entirety as follows:

“2. In the event that, on a country-by-country basis, one or more patents are issued by the patent authority in that country and contain a Valid Claim, Gelesis LLC shall pay to PureTech Ventures, LLC two percent (2%) of Net Sales of such Licensed Product during the Calendar Year. For the avoidance of doubt there is no increase to the royalty for more than one Valid Claim. In the event that, on a country-by country basis, there is no Valid Claim, Gelesis LLC shall pay to PureTech five percent (5%) of any royalty paid to Gelesis, LLC by AstraZeneca pursuant to Section 10. 5. 2 (i. e. Royalty Scenario 2) of the Gelesis/AZ Agreement. The royalties referred to in Section 2 shall (i) be paid to PureTech within thirty (30) days following receipt of such royalty by Gelesis, LLC from AstraZenca and (b) be subject to all of the same adjustments as the royalties payable to Gelesis, LLC under the AstraZeneca Agreement.”

Solely for purposes of this Section 1 of this Amendment No. 1, all capitalized terms shall have the meanings ascribed to them in the Gelesis/AZ Agreement.

3. In the event that the Gelesis/AZ Agreement is terminated, PureTech may request in writing that the Amendments set forth in Section 2 of this Amendment No. 1 be terminated. In such event, the amendment set forth in Section 2 of this Amendment No. 1 shall terminate and be of no further force or effect.

4. The Agreement (including Amendment No. 1) are hereby confirmed and continue in all other respects.
