51.2 Notwithstanding any other provisions of these Articles, if any ordinary shares in the capital of the Company are allotted and issued to any person (a New Member) other than Thomson Reuters Corporation and/or its nominee or nominees after the time at which this Article becomes effective and before 6.00 p.m. on the business day before the date on which the Court confirms the Thomson Reuters PLC Reduction of Capital (as defined in the Scheme), such ordinary shares in the share capital of the Company shall be allotted and issued subject to the terms of the Scheme and shall be Scheme Shares for the purposes thereof and the New Member, and any subsequent holder other than Thomson Reuters Corporation and/or its nominee or nominees, shall be bound by the terms of the Scheme.

51.3 Subject to the Scheme becoming effective, if any ordinary shares in the share capital of the Company are issued and allotted to a New Member at or after 6.00 p.m. on the business day before the date on which the Court confirms the Thomson Reuters PLC Reduction of Capital (the Post-Scheme Shares), they will, on receipt by the Company of an election in writing from Thomson Reuters Corporation, be immediately transferred to Thomson Reuters Corporation and/or its nominee in consideration of and conditional upon the issue or transfer to the New Member of one Thomson Reuters Corporation Share for each Post-Scheme Share, so transferred. Any Thomson Reuters Corporation Shares issued pursuant to this Article 51 to the New Member will be credited as fully paid and will rank equally in all respects with all Thomson Reuters Corporation Shares in issue at the time (other than as regards any dividend or other distribution payable, or return of capital made, by reference to a record time preceding the date of exchange) and will be subject to the Articles and By-Laws of Thomson Reuters Corporation.

51.4 The number of Thomson Reuters Corporation Shares to be issued or transferred to the New Member under this Article 51 may be adjusted by the directors of the Company in such manner as the Company's auditors may determine on any reorganisation or material alteration of the share capital of either the Company or of Thomson Reuters Corporation or any other return of value to holders of Thomson Reuters Corporation Shares, provided always that any fractions of Thomson Reuters Corporation Shares shall be disregarded and shall be aggregated and sold for the benefit of Thomson Reuters Corporation.

51.5 In order to give effect to any such transfer required by this Article 51, the Company may appoint any person to execute and deliver a form of transfer on behalf of the New Member in favour of Thomson Reuters Corporation and/or its nominee or nominees and to agree for and on behalf of the New Member to become a member of Thomson Reuters Corporation. Pending the registration of Thomson Reuters Corporation as a holder of any Post-Scheme Shares to be transferred pursuant to this Article 51, Thomson Reuters Corporation shall be empowered to appoint a person nominated by the directors of the Company to act as attorney on behalf of the holder of the Post-Scheme Shares in accordance with such directions as Thomson Reuters Corporation may give in relation to any dealings with or disposal of the Post-Scheme Shares (or any interest therein), exercising any rights attached thereto or receiving any distribution or other benefit accruing or payable in respect thereof and any holder of Post-Scheme Shares shall exercise all rights attached thereto in accordance with the directions of Thomson Reuters Corporation but not otherwise.

51.7 The provisions of this Article 51 shall be subject to any prohibition or condition imposed by law. Without prejudice to the generality of the foregoing, if, in respect of any holder of Scheme Shares with a registered address in a jurisdiction outside the United Kingdom, Thomson Reuters Corporation is advised that the allotment and/or issue of Thomson Reuters Corporation Shares pursuant to this Article 51 would or might infringe the laws of such jurisdiction or would or may require Thomson Reuters Corporation to observe any governmental or other consent or any registration, filing or other formality, with which Thomson Reuters Corporation is unable to comply or with which Thomson Reuters Corporation regards it unduly onerous to comply, Thomson Reuters Corporation may, in its sole discretion, either:

(a) determine that the Thomson Reuters Corporation Shares shall not be allotted and/or issued to such holder under this Article 51 but shall instead be allotted and issued (directly on Thomson Reuters Corporation’s shareholder register either through the direct registration system or through holding share certificates) to a nominee appointed by Thomson Reuters Corporation as nominee for such holder on terms that the nominee shall, as soon as practicable following such allotment and issue, sell the Thomson Reuters Corporation Shares so allotted and issued on behalf of such holder at the best price which can reasonably be obtained at the time of sale and account for the net proceeds of such sale (after the deduction of all expenses and commissions, including any amounts in respect of value added tax payable thereon) by sending a cheque or creating a payment instruction in accordance with the provisions of Article 42.14 (Method of cash dividend payments) mutatis mutandis. In the absence of bad faith or wilful default, none of the Company, Thomson Reuters Corporation or the nominee shall have any liability for any loss or damage arising as a result of the timing or terms of such sale; or

(b) determine that the Thomson Reuters Corporation Shares shall be sold, in which event the Thomson Reuters Corporation Shares shall be issued to such holder (directly on Thomson Reuters Corporation’s shareholder register either through the direct registration system or through holding share certificates) and Thomson Reuters Corporation shall appoint a person to act pursuant to this Article 51(6)(b) and such person shall be authorized on behalf of such holder to procure that any shares in respect of which Thomson Reuters Corporation has made such determination shall as soon as practicable following such issue be sold at the best price which can reasonably be obtained at the time of sale and the net proceeds of such sale (after the deduction of all expenses and commissions, including any amounts in respect of value added tax payable thereon) shall be paid to such holder by sending a cheque or creating a payment instruction in accordance with the provisions of Article 42.14 (Method of cash dividend payments) mutatis mutandis. To give effect to any such sale, the person so appointed shall be authorized on behalf of such holder to execute and deliver a form of transfer and to give such instructions and to do all other things which he may consider necessary or expedient in connection with such sale. In the absence of bad faith or wilful default, none of the Company, Thomson Reuters Corporation or the person so appointed shall have any liability for any loss or damage arising as a result of the timing or terms of such sale.”;
