THIS LOCK-UP AGREEMENT (this “Agreement”) is made and entered into as of [●], 2025 by and between StableCoinX Inc., a Delaware corporation (the “Company”) and each of the undersigned holders (and any person who hereafter becomes a party to this Agreement pursuant to Section 1, each, a “Holder” and collectively, the “Holders”). Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the Business Combination Agreement (as defined below).

WHEREAS, on July 21, 2025, TLGY Acquisition Corporation, a Cayman Islands exempted company (“SPAC”), the Company, StableCoinX SPAC Merger Sub LLC, a Delaware limited liability company and a wholly-owned subsidiary of Pubco (“SPAC Merger Sub”), StableCoinX Company Merger Sub, Inc., a Delaware limited liability company and a wholly-owned subsidiary of Pubco (“Company Merger Sub”), and StableCoinX Assets Inc., a Delaware corporation (the “OpCo”), entered into that certain Business Combination Agreement (as amended from time to time, the “Business Combination Agreement”);

WHEREAS, pursuant to the Business Combination Agreement, upon the consummation (the “Closing”) of the transactions contemplated by the Business Combination Agreement (the “Transactions”), among other things, (a) SPAC merged with and into SPAC Merger Sub, with SPAC Merger Sub continuing as the surviving entity (the “SPAC Merger”), as a result of which the SPAC Shareholders received one share of Class A common stock, par value $0.0001 per share, of the Company (“Class A Common Stock”) for each SPAC Class A Ordinary Share held by such shareholder and (b) immediately following the SPAC Merger, Company Merger Sub merged with and into Opco, with Opco continuing as the surviving company (the “Company Merger”, and together with the SPAC Merger, the “Mergers”), as a result of which the holders of shares of Class A common stock, par value $0.0001 per share, of Opco (the “Opco Class A Common Stock”), received one share of Class A Common Stock for each share of Opco Class A Common Stock held by such holder and the holders of shares of Class B common stock, par value $0.0001 per share, of Opco (the “Opco Class B Common Stock”) received one share of Class A Common Stock and one share of Class B Common Stock, par value $0.0001 per share, of the Company (the “Class B Common Stock”) for each share of Opco Class B Common Stock held by such holder. As a result of the Mergers, SPAC and Opco became wholly owned subsidiaries of Pubco, and Pubco became a publicly traded company;

WHEREAS, in accordance with the terms of that certain Sponsor Support Agreement, dated as of July 21, 2025, by and among the Company, SPAC, Opco, certain of the Holders and the other parties thereto, certain Holders party thereto are entitled to receive newly issued shares of Class A Common Stock upon the occurrence of certain events after the Closing (the “Earnout Shares”);

WHEREAS, as of the date hereof, each Holder is a holder of shares of Class A Common Stock (including any Earnout Shares) in such amount as set forth underneath such Holder’s name on the signature page hereto; and

WHEREAS, pursuant to the Business Combination Agreement and the Transactions, and in view of the valuable consideration to be received by Holder thereunder, the receipt and sufficiency of which is hereby acknowledged, the parties desire to enter into this Agreement, pursuant to which the shares of Class A Common Stock (including any Earnout Shares) received by each Holder in the Transactions (all such securities, including, without limitation, any securities into which any of such securities are exchanged or converted, the “Restricted Securities”), shall become subject to limitations on disposition as set forth herein.

NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to be legally bound hereby, the parties hereby agree as follows:

1. Lock-Up Provisions.

(a) Holder hereby agrees not to, without the prior written consent of the Company, during the period (the “Lock-Up Period”) commencing from the Closing Date and ending on the earlier of (A) the six (6) month anniversary of the Closing Date and (B) the date on which the Company consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of its stockholders having the right to exchange their shares of common stock of the Company for cash, securities or other property: (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidation with respect to or decrease a call equivalent position within the meaning of Section 16 of the Securities and Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to, any Restricted Securities, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Restricted Securities, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce the intention to effect any transaction specified in clause (i) or (ii) (any of the foregoing described in clauses (i), (ii) or (iii), a “Prohibited Transfer”). The foregoing sentence shall not apply to the transfer of any or all of the Restricted Securities owned by Holder (each, a “Permitted Transferee”): (I) in the case of an entity, transfers (A) to another entity that is an Affiliate of the Holder, (B) as part of a distribution to members, partners or stockholders of Holder and (C) to officers or directors of Holder, any Affiliate or family member of any of Holder’s officers or directors, or to any members, officers, directors or employees of Holder or any of its Affiliates; (II) in the case of an individual, transfers by gift to members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family or an Affiliate of such person; (III) to a charitable organization; (IV) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual or for bona fide estate planning purposes; (V) in the case of an individual, transfers pursuant to a qualified domestic relations order; (VI) in the case of an entity, transfers by virtue of the laws of the state of the entity’s organization and the entity’s organizational documents upon dissolution or liquidation of the entity; (VII) transfers to the Company; (VIII) transfers to satisfy any U.S. federal, state, or local income tax obligations of Holder (or its direct or indirect owners) to the extent necessary to cover any tax liability as a direct result of the Transactions; or (IX) in the form of a pledge of Restricted Securities in a bona fide transaction as collateral to secure obligations pursuant to lending or other financing arrangements between a Holder (or its Affiliates), on the one hand, and a third party, on the other hand, for the benefit of such Holder and/or its Affiliates; provided, however, that during the Lock-Up Period such third party shall not be permitted to foreclose upon such Restricted Securities or otherwise be entitled to enforce its rights or remedies with respect to the Restricted Securities, including, without limitation, the right to vote, transfer or take title to or ownership of such Restricted Securities; provided, however, that it shall be a condition to any transfer pursuant to clauses (I) through (IX) above that the Permitted Transferee executes and delivers to the Company an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further transfer of such Restricted Securities except in accordance with this Agreement. Holder further agrees to execute such agreements as may be reasonably requested by the Company that are consistent with the foregoing or that are necessary to give further effect thereto. The restrictions set forth herein shall not restrict Holder from making a request for inclusion of its Restricted Securities in any registration statement pursuant to any registration rights agreement between the Company and the Holder, provided that no public filing or public disclosure relating to such sale of securities is made during the Lock-Up Period.

(b) If any Prohibited Transfer is made or attempted contrary to the provisions of this Agreement, such purported Prohibited Transfer shall be null and void ab initio, and the Company shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders for any purpose. In order to enforce this Section 1, the Company may impose stop-transfer instructions with respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-Up Period.

(c) During the Lock-Up Period, each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2025, BY AND BETWEEN THE ISSUER OF SUCH SECURITIES (THE “ISSUER”) AND THE ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

(d) For the avoidance of any doubt, Holder shall retain all of its rights as a stockholder of the Company during the Lock-Up Period, including the right to vote any Restricted Securities.

(e) Notwithstanding anything in this Agreement to the contrary, the board of directors of the Company shall be entitled to release any Holder from any or all of its obligations hereunder on behalf of the Company; provided, however, that if one Holder is released, the other Holders shall also be similarly released to the same relative extent as the released Holder.

2. Effectiveness; Termination. This Agreement shall be effective upon consummation of the transactions contemplated by the Business Combination Agreement and shall terminate on the date on which Holder no longer holds Restricted Securities.

3. Miscellaneous.

(a) Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of a Holder are personal to such Holder and may not be transferred or delegated by such Holder at any time without the prior written consent of the Company, except in accordance with the procedures set forth for transfers of Restricted Securities to Permitted Transferees in Section 1(a), and any such purported transfer shall be null and void. The Company may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder.

(b) Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person or entity that is not a party hereto or thereto or a successor or permitted assign of such a party.

(c) Governing Law; Jurisdiction; Specific Performance. Sections 11.6 and 11.7 of the Business Combination Agreement shall apply to this Agreement mutatis mutandis.

(d) Interpretation. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without limitation”; (iii) the words “herein,” “hereto,” and “hereby” and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as a whole and not to any particular section or other subdivision of this Agreement; and (iv) the term “or” means “and/or”. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(e) Notices. All notices, consents, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered (i) in person, (ii) by electronic means (including email), with affirmative confirmation of receipt, (iii) one Business Day after being sent, if sent by reputable, nationally recognized overnight courier service or (iv) three (3) Business Days after being mailed, if sent by registered or certified mail, pre-paid and return receipt requested, in each case to the applicable party at the following addresses (or at such other address for a party as shall be specified by like notice):

(f) Amendments and Waivers. This Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed by (i) the Company and (ii) Holders holding a majority of the Class A Common Stock that are then subject to this Agreement; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that materially and adversely affects a Holder, solely in its capacity as a holder of Restricted Securities, shall require the consent of the Holder so affected. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. 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.

(g) Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a court of competent jurisdiction, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

(h) Entire Agreement. This Agreement, together with the Business Combination Agreement to the extent referred to herein, constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the parties under the Business Combination Agreement or any Ancillary Document. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies of the Company or any of the rights, remedies or obligations of Holder under any other agreement between Holder and the Company or any certificate or instrument executed by Holder in favor of the Company, and nothing in any other agreement, certificate or instrument shall limit any of the rights, remedies or obligations of the Company or any of the rights, remedies or obligations of Holder under this Agreement.

(i) Further Assurances. From time to time, at another party’s reasonable request and without further consideration (but at the requesting party’s reasonable cost and expense), each party shall execute and deliver such additional documents and take all such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

(j) Counterparts. This Agreement may be executed and delivered (including by electronic signature or by email in portable document form) in two or more counterparts and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

(k) Several Liability. The liability of any Holder hereunder is several (and not joint). Notwithstanding any other provision of this Agreement, in no event will any Holder be liable for any other Holder’s breach of such other Holder’s obligations under this Agreement.
