Termination and Amendment of Deposit Agreement

WNS (Holdings) Limited (the “Company”) intends to give notice to Deutsche Bank Trust Company Americas (the “Depositary”) to terminate the Deposit Agreement, dated as of July 18, 2006 (as amended, the “Deposit Agreement”), among the Company, the Depositary and the holders and beneficial owners of American Depositary Shares (“ADSs”) evidenced by American Depositary Receipts (“ADRs”) issued thereunder, in order to exchange the outstanding ADSs for ordinary shares, par value 10 pence per share (“Shares”), of the Company, and to cause the Shares to be listed and traded on the New York Stock Exchange (the “NYSE”) in lieu of ADSs. The Company anticipates the Shares will be listed on the NYSE by March 31, 2024 and trade under the symbol “WNS.”

In connection with such termination, the Company and the Depositary have agreed to amend the Deposit Agreement (the “Amendment”) to shorten the notice period in connection with the termination of the Deposit Agreement by the Company from 90 days to 30 days.

The Depositary will give holders of ADSs notice of the Amendment today, which will become effective on February 25, 2024, being 30 days after such notice of Amendment.

SECTION 2.1 All references in the Deposit Agreement to the form of American Depositary Receipt set out in Exhibit A and Exhibit B thereto shall, as of the Effective Date (as defined herein), refer to the Receipts as amended by this Amendment.

SECTION 2.2 As of the Effective Date, Section 6.2 (Termination) shall be replaced in its entirety with the following:

“SECTION 6.2 Termination. The Depositary shall, at any time at the written direction of the Company, terminate this Deposit Agreement by mailing notice of such termination to the Holders of all Receipts then outstanding at least 30 days prior to the date fixed in such notice for such termination, provided that the Depositary shall be reimbursed for any amounts, fees, costs or expenses owed to it in accordance with the terms of this Deposit Agreement and in accordance with any other agreements as otherwise agreed in writing between the Company and the Depositary from time to time, prior to such termination shall take effect. If 90 days shall have expired after (i) the Depositary shall have delivered to the Company a written notice of its election to resign, or (ii) the Company shall have delivered to the Depositary a written notice of the removal of the Depositary, and in either case a successor depositary shall not have been appointed and accepted its appointment as provided in Section 5.4, the Depositary may terminate this Deposit Agreement by mailing notice of such termination to the Holders of all Receipts then outstanding at least 30 days prior to the date fixed for such termination.

On and after the date of termination of this Deposit Agreement, the Holder will, upon surrender of such Receipt at the Principal Office of the Depositary, upon the payment of the charges of the Depositary for the surrender of Receipts referred to in Section 2.6 and subject to the conditions and restrictions therein set forth, and upon payment of any applicable taxes or governmental charges, be entitled to delivery, to him or upon his order, of the amount of Deposited Securities represented by such Receipt. If any Receipts shall remain outstanding after the date of termination of this Deposit Agreement, the Registrar thereafter shall discontinue the registration of transfers of Receipts, and the Depositary shall suspend the distribution of dividends to the Holders thereof, and shall not give any further notices or perform any further acts under this Deposit Agreement, except that the Depositary shall continue to collect dividends and other distributions pertaining to Deposited Securities, shall sell rights or other property as provided in this Deposit Agreement, and shall continue to deliver Deposited Securities, subject to the conditions and restrictions set forth in Section 2.6, together with any dividends or other distributions received with respect thereto and the net proceeds of the sale of any rights or other property, in exchange for Receipts surrendered to the Depositary (after deducting, or charging, as the case may be, in each case, the charges of the Depositary for the surrender of a Receipt, any expenses for the account of the Holder in accordance with the terms and conditions of this Deposit Agreement and any applicable taxes or governmental charges or assessments). At any time after the expiration of six months from the date of termination of this Deposit Agreement, the Depositary may sell the Deposited Securities then held hereunder and may thereafter hold uninvested the net proceeds of any such sale, together with any other cash then held by it hereunder, in an unsegregated account, without liability for interest for the pro rata benefit of the Holders of Receipts whose Receipts have not theretofore been surrendered. After making such sale, the Depositary shall be discharged from all obligations under this Deposit Agreement with respect to the Receipts and the Shares, Deposited Securities and American Depositary Shares, except to account for such net proceeds and other cash (after deducting, or charging, as the case may be, in each case, the charges of the Depositary for the surrender of a Receipt, any expenses for the account of the Holder in accordance with the terms and conditions of this Deposit Agreement and any applicable taxes or governmental charges or assessments). Upon the termination of this Deposit Agreement, the Company shall be discharged from all obligations under this Deposit Agreement except for its obligations to the Depositary hereunder.”

If 90 days shall have expired after (i) the Depositary shall have delivered to the Company a written notice of its election to resign, or (ii) the Company shall have delivered to the Depositary a written notice of the removal of the Depositary, and in either case a successor depositary shall not have been appointed and accepted its appointment as provided herein and in the Deposit Agreement, the Depositary may terminate the Deposit Agreement by mailing notice of such termination to the Holders of all Receipts then outstanding at least 30 days prior to the date fixed for such termination.

On and after the date of termination of the Deposit Agreement, the Holder will, upon surrender of such Receipt at the Principal Office of the Depositary, upon the payment of the charges of the Depositary for the surrender of Receipts referred to in Article (2) hereof and in the Deposit Agreement and subject to the conditions and restrictions therein set forth, and upon payment of any applicable taxes or governmental charges, be entitled to delivery, to him or upon his order, of the amount of Deposited Securities represented by such Receipt. If any Receipts shall remain outstanding after the date of termination of the Deposit Agreement, the Registrar thereafter shall discontinue the registration of transfers of Receipts, and the Depositary shall suspend the distribution of dividends to the Holders thereof, and shall not give any further notices or perform any further acts under the Deposit Agreement, except that the Depositary shall continue to collect dividends and other distributions pertaining to Deposited Securities, shall sell rights as provided in the Deposit Agreement, and shall continue to deliver Deposited Securities, subject to the conditions and restrictions set forth in the Deposit Agreement, together with any dividends or other distributions received with respect thereto and the net proceeds of the sale of any rights or other property, in exchange for Receipts surrendered to the Depositary (after deducting, or charging, as the case may be, in each case, the charges of the Depositary for the surrender of a Receipt, any expenses for the account of the Holder in accordance with the terms and conditions of the Deposit Agreement and any applicable taxes or governmental charges or assessments).
