Re: Restricted ADSs (CUSIP No.: 000000000)

Ladies and Gentlemen:

Reference is made to the Deposit Agreement, dated as of dated as of May 2, 2017, as amended and supplemented from time to time (the “Deposit Agreement”), by and among Verona Pharma plc, a public limited company incorporated under the laws of England and Wales, and its successors (the “Company”), Citibank, N.A., a national banking association (“Citibank”) organized and existing under the laws of the United States of America, as Depositary (the “Depositary”), and all Holders and Beneficial Owners of American Depositary Shares (the “ADSs”) issued thereunder. All capitalized terms used, but not otherwise defined herein, shall have the meaning assigned thereto in the Deposit Agreement.

The Company desires to establish procedures to enable certain investors in the Company, including Affiliates of the Company, the names of which are to be provided to the Depositary from time to time (each, a “Restricted Holder”), to hold Shares that constitute Restricted Securities as Restricted ADSs. The Depositary agrees to accommodate the issuance of Restricted ADSs, provided that (a) the terms of deposit of the Restricted Securities for Restricted ADSs neither (i) prejudice any substantial rights of existing Holders and Beneficial Owners of ADSs under the Deposit Agreement, nor (ii) violate or conflict with any law, rule or administrative position applicable to the ADSs, and (b) the terms of the Deposit Agreement are supplemented as set forth in this letter agreement (the “Restricted ADS Letter Agreement”) to establish procedures for the deposit of Restricted Securities by the Company, or by, for, or on behalf of, Restricted Holders.

The purpose and intent of this Restricted ADS Letter Agreement is to supplement the Deposit Agreement for the purpose of accommodating (i) the issuance of Restricted ADSs to the Restricted Holders, (ii) the sale or transfer of such Restricted ADSs, and (iii) certain ancillary transactions further described below. The Company and the Depositary agree that this Restricted ADS Letter Agreement shall be filed as an exhibit to the Company's next Registration Statement on Form F-6 filed in respect of the ADSs under the U.S. Securities Act of 1933, as amended (the “Securities Act”), if any.

For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Depositary hereby agree, notwithstanding the terms of the Deposit Agreement, as follows:

1. Depositary Procedures. The Company consents, under Section 2.3 of the Deposit Agreement, to (i) the deposit by the Company, or by, for, or on behalf of, each Restricted Holder, of up to the number of Shares listed opposite such Restricted Holder’s name on lists to be provided to the Depositary from time to time in writing together with a written request for the Depositary to accept the deposit of such Shares (which request shall not be unreasonably denied) (the “Restricted Shares”) and (ii) the issuance and delivery by the Depositary of the corresponding number of Restricted ADSs in respect thereof in the form of Uncertificated ADSs, upon the terms set forth in Section 2.13 of the Deposit Agreement, as supplemented by this Restricted ADS Letter Agreement, to the Restricted Holders or their respective designees. The Restricted ADSs described in the immediately preceding sentence and the Restricted Shares represented thereby are referred to herein as the “Designated Restricted ADSs” and the “Designated Shares”, respectively. In connection with each deposit of Designated Shares (i) by the Company and request for issuance of Designated Restricted ADSs, the Company shall deliver to the Depositary a duly completed and signed Consent and Delivery Instruction substantially in the form of Exhibit A-1 hereto (each a “Consent and Delivery Instruction - Company”), and (ii) by a Restricted Holder and request for issuance of Designated Restricted ADSs, the Restricted Holder shall be required to deliver to the Depositary a duly completed and signed Consent and Delivery Instruction substantially in the form of Exhibit A-2 hereto (each a “Consent and Delivery Instruction – Restricted Holder” and together with a Consent and Delivery Instruction – Company, a “Consent and Delivery Instruction”).

In furtherance of the foregoing, the Company instructs the Depositary, and the Depositary agrees, upon the terms and subject to the conditions set forth in Section 2.14 of the Deposit Agreement as supplemented by this Restricted ADS Letter Agreement, to (i) establish procedures to enable (x) the deposit of the Designated Shares with the Custodian by the Company, or by, for, or on behalf of, the Restricted Holders as a valid deposit of Shares under the Deposit Agreement in order to enable the issuance by the Depositary to the Restricted Holders of Designated Restricted ADSs issued under the terms of this Restricted ADS Letter Agreement upon deposit of Designated Shares, and (y) the transfer of the Designated Restricted ADSs, the removal of the transfer and other restrictions with respect to Designated Restricted ADSs in order to create unrestricted ADSs, and the withdrawal of the Designated Shares, in each case upon the terms and conditions set forth in the Deposit Agreement as supplemented by the terms of this Restricted ADS Letter Agreement, and (ii) deliver an account statement (the “Account Statement”) to the Restricted Holder(s) upon the issuance of the Designated Restricted ADSs, in each case upon the terms set forth herein. Nothing contained in this Restricted ADS Letter Agreement shall in any way obligate the Depositary, or give authority to the Depositary, to accept any Shares other than the Designated Shares described herein for deposit under the terms hereof.

2. Company Assistance. The Company agrees to (i) provide commercially reasonable assistance upon the request of and to the Depositary in the establishment of such procedures to enable the acceptance of the deposit by or on behalf of the Restricted Holders of the Designated Shares, the issuance of Designated Restricted ADSs, the transfer of Designated Restricted ADSs, the withdrawal of the Designated Shares and the conversion of Designated Restricted ADSs into freely transferable ADSs, and (ii) take all commercially reasonable steps requested by the Depositary to ensure that the acceptance of the deposit of the Designated Shares, the issuance of the Designated Restricted ADSs, the transfer of the Designated Restricted ADSs, the conversion of Designated Restricted ADSs into freely transferable ADSs, and the withdrawal of Designated Shares, in each case upon the terms and conditions set forth herein, do not prejudice any substantial existing rights of Holders or Beneficial Owners of ADSs and do not violate the provisions of the Securities Act or any other applicable laws.

In furtherance of the foregoing, on or prior to the date of the first deposit of Designated Shares pursuant to a Consent and Delivery Instruction (and, solely with respect to clause (A)(ii) below, on or prior to each subsequent deposit of Designated Shares pursuant to a Consent and Delivery Instruction), the Company shall cause (A) its U.S. counsel to deliver an opinion to the Depositary stating, inter alia, that (i) assuming its due authorization, execution and delivery, this Restricted ADS Letter Agreement is valid, binding and enforceable against the Company under the laws of the State of New York, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally, and as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and (ii) the deposit of such specified Designated Shares by the Company, or by, for, or on behalf of, such Restricted Holders and the issuance and delivery of such Designated Restricted ADSs, in each case upon the terms contemplated herein, do not require registration of such Designated Shares under the Securities Act, and (B) its England and Wales counsel to deliver an opinion to the Depositary stating, inter alia, that (i) the Company has duly authorized and executed this Restricted ADS Letter Agreement, (ii) this Restricted ADS Letter Agreement constitutes a legal, valid and binding obligation of the Company under the laws of England and Wales enforceable against the Company upon its terms, (iii) all approvals required by the laws of England and Wales to permit the deposit of Designated Shares under the Deposit Agreement and this Restricted ADS Letter Agreement have been obtained, and (iv) the terms of this Restricted ADS Letter Agreement and the transactions contemplated by this Restricted ADS Letter Agreement do not contravene or conflict with any laws of England and Wales of general application.

3. Limitations on Issuance of Restricted ADSs. The Company hereby instructs the Depositary, and the Depositary agrees, upon the terms and subject to the conditions set forth in this Restricted ADS Letter Agreement, to issue and deliver Designated Restricted ADSs only (x) in the case of initial issuance upon receipt of (i) a duly completed and signed Consent and Delivery Instruction from the Company or the Restricted Holder, as applicable, (ii) confirmation from the Custodian of the receipt of the due deposit of the Designated Shares by the Company, or by, for, or on behalf of, a Restricted Holder, and (iii) payment of the applicable fees, taxes and expenses otherwise payable under the terms of the Deposit Agreement upon the deposit of Shares and the issuance of ADSs, and (y) in the event of any corporate action of the Company which results in the issuance of Restricted ADSs to the holder(s) of the Designated Restricted ADSs.

The Depositary shall cause the Designated Restricted ADSs issued upon the deposit of Designated Shares to be separately identified on the books of the Depositary under Cusip No.: 000000000 (which may also be used by the Depositary to identify other Restricted ADSs to be issued under the terms of the Deposit Agreement pursuant to other Restricted ADS letter agreements between the Company and the Depositary) and the Designated Shares to be held, to the extent practicable, separate and distinct by the Custodian from the other Deposited Securities held by the Custodian in respect of the ADSs issued under the Deposit Agreement that are not Restricted ADSs.

The Depositary is hereby authorized and directed notwithstanding the terms of Section 2.14 of the Deposit Agreement) to issue the Designated Restricted ADSs as Uncertificated Restricted ADSs registered in the books of the Depositary in the name of the Restricted Holders or their designees for the benefit of the Restricted Holders subject to the restrictions specified in Section 4 below.

4. Stop Transfer Notation and Legend. The books of the Depositary shall identify the Designated Restricted ADSs as “restricted” and shall contain a “stop transfer” notation to that effect. The Account Statements to be sent by the Depositary to the Restricted Holders upon the issuance of Designated Restricted ADSs shall contain a legend substantially to the form of the following legend:

THE RESTRICTED AMERICAN DEPOSITARY SHARES (“RESTRICTED ADSs”) CREDITED TO YOUR ACCOUNT AND THE UNDERLYING RESTRICTED SHARES (“RESTRICTED SHARES”) OF VERONA PHARMA PLC (THE “COMPANY”) ARE SUBJECT TO THE TERMS OF A RESTRICTED ADS LETTER AGREEMENT (AS AMENDED AND SUPPLEMENTED FROM TIME TO TIME, THE “RESTRICTED ADS LETTER AGREEMENT”), DATED AS OF OCTOBER 19, 2020, AND THE DEPOSIT AGREEMENT, DATED AS OF MAY 2, 2017, AS AMENDED AND SUPPLEMENTED (AS SO AMENDED AND SUPPLEMENTED, THE “DEPOSIT AGREEMENT”).

THESE SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO (A) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT IN A TRANSACTION REGISTERED OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS, OR (B) AN AVAILABLE EXEMPTION FROM SUCH REGISTRATION OR QUALIFICATION REQUIREMENTS, UNLESS A REGISTRATION STATEMENT IS EFFECTIVE WITH RESPECT TO THESE SECURITIES. AS A CONDITION TO PERMITTING ANY TRANSFER OF THESE SECURITIES, EACH OF CITIBANK, N.A. IN ITS CAPACITY AS THE DEPOSITARY FOR THE RESTRICTED ADSs (THE “DEPOSITARY”) AND THE COMPANY MAY REQUIRE THAT IT BE FURNISHED WITH AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE DEPOSITARY AND THE COMPANY TO THE EFFECT THAT NO REGISTRATION OR QUALIFICATION IS LEGALLY REQUIRED FOR SUCH TRANSFER.

PRIOR TO THE SALE OF THE RESTRICTED ADSs AND ISSUANCE OF FREELY TRANSFERABLE ADSs IN RESPECT THEREOF, A HOLDER OF RESTRICTED ADSs WILL BE REQUIRED TO PROVIDE TO THE DEPOSITARY AND TO THE COMPANY A CERTIFICATION AND INSTRUCTION LETTER IN THE FORM ATTACHED TO THE RESTRICTED ADS LETTER AGREEMENT.

THE TRANSFER AND OTHER RESTRICTIONS SET FORTH HEREIN AND IN THE RESTRICTED ADS LETTER AGREEMENT SHALL REMAIN APPLICABLE WITH RESPECT TO THE RESTRICTED ADSs AND THE RESTRICTED SHARES UNTIL SUCH TIME AS THE PROCEDURES SET FORTH IN THE RESTRICTED ADS LETTER AGREEMENT FOR REMOVAL OF RESTRICTIONS ARE SATISFIED. NEITHER THE COMPANY NOR THE DEPOSITARY MAKES ANY REPRESENTATION AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT FOR RESALE OF THE RESTRICTED SHARES OR THE RESTRICTED ADSs. A COPY OF THE DEPOSIT AGREEMENT AND OF THE RESTRICTED ADS LETTER AGREEMENT MAY BE OBTAINED FROM THE DEPOSITARY OR THE COMPANY UPON REQUEST.

5. Limitations on Transfer of Designated Restricted ADSs. The Designated Restricted ADSs shall be transferable only by the Restricted Holder thereof upon delivery to the Depositary of (i) all applicable documentation otherwise contemplated by the Deposit Agreement and payment of the applicable fees, taxes and expenses otherwise payable in connection with the transfer of ADSs under the terms of the Deposit Agreement and this Restricted ADS Letter Agreement (US$0.05 per Restricted ADS transferred), and, (ii) a Transfer Certification from the transferring Restricted Holder substantially in the form attached hereto as Exhibit B and (iii) such other documents as may reasonably be requested by the Depositary under the terms hereof (including, without limitation, opinions of U.S. counsel as to compliance with the terms of the legend set forth above in Section 4).

6. Limitations on Cancellation of Designated Restricted ADSs.

7. Fungibility. Except as contemplated herein and except as required by applicable law, the Designated Restricted ADSs shall, to the maximum extent permitted by law and to the maximum extent practicable, be treated as ADSs issued and outstanding under the terms of the Deposit Agreement that are not Restricted ADSs. Nothing contained herein shall obligate the Depositary to treat Holders of Designated Restricted ADSs on terms more favorable than those accorded to Holders of ADSs under the Deposit Agreement.

8. Limitations on Exchange of Designated Restricted ADSs for Freely Transferrable ADSs. The Company instructs the Depositary, and the Depositary agrees, to cancel the Designated Restricted ADSs and to issue and deliver freely transferable ADSs in respect thereof upon receipt of (i) a duly completed and signed Resale Certification and Instruction Letter, substantially in the form attached hereto as Exhibit D (the “Resale Certification and Instruction Letter”), (ii) an opinion of U.S. securities counsel contemplated in the Resale Certification and Instruction Letter, (iii) payment of the applicable ADS issuance and cancellation fees, taxes and expenses otherwise payable under the terms of the Deposit Agreement and this Restricted ADS Letter Agreement, and (iv) any other documents as may reasonably be requested by the Depositary under the terms of the Deposit Agreement and this Restricted ADS Letter Agreement.

9. Removal of Restrictions. The Depositary shall remove all stop transfer notations from its records in respect of specified Designated Restricted ADSs and shall treat such Designated Restricted ADSs on the same terms as the ADSs outstanding under the terms of the Deposit Agreement that are not Restricted ADSs upon receipt of (x) written instructions from the Company to so remove all stop transfer notations from its records in respect of specified Designated Restricted ADSs and to treat such Designated Restricted ADSs on the same terms as the ADSs outstanding under the terms of the Deposit Agreement that are not Restricted ADSs, (y) an opinion of U.S. counsel to the Company stating, inter alia, that the removal of the restrictive notations with respect to Designated Restricted ADSs and the Designated Shares, and the treatment of such Designated Restricted ADSs on the same terms as the ADSs outstanding under the terms of the Deposit Agreement that are not Restricted ADSs, do not violate the registration requirements of the Securities Act, and (z) payment of the applicable ADS issuance and cancellation fees, taxes and expenses otherwise payable under the terms of the Deposit Agreement and this Restricted ADS Letter Agreement. Upon receipt of such instructions, opinion of counsel, and payment of applicable fees, taxes and expenses, the Depositary shall take all actions necessary to remove any distinctions previously existing between the applicable Designated Restricted ADSs and the ADSs that are not Restricted ADSs, including, without limitation, by (a) removing the stop transfer notations on its records in respect of the applicable ADSs previously identified as Designated Restricted ADSs, and (b) making the formerly Designated Restricted ADSs eligible for inclusion in the applicable book-entry settlement system.
