WHEREAS, in connection with the Business Combination Agreement and Transactions, the Parties desire to amend the Agreement.

NOW, THEREFORE, in consideration of the covenants and agreements contained herein, the Parties hereto agree as follows:

1. Addition of Pubco. Pubco hereby agrees to the provisions of, and joins as a party to, the Agreement as in effect as of the date hereof, mutatis mutandis, and all references to “Company” in the Agreement shall be deemed to refer to each of the Company and Pubco, as applicable. By executing below, Pubco is deemed to have executed the Agreement with the same force and effect as if originally named a party thereto. For the avoidance of doubt, the Parties acknowledge that the provisions of Article 2 (excluding Section 2.01(c)), Section 3.01 and Section 3.04 of the Agreement do not apply to Pubco.

2. Investor Rights Agreement. The Parties hereby agree that all references in the Agreement to the Investor Rights Agreement shall, solely with respect to Pubco, be deemed to refer to the Investor Rights Agreement by and among Pubco, Leopard, Leopard Parent, Dragon, Dragon Parent, Mammoth and the Mammoth Funds, dated as of May 13, 2024 (the “Pubco IRA”), and the reference to Section 4.01(a) of the Investor Rights Agreement in Section 4.04(c) of the Agreement shall not apply with respect to Pubco.

3. Other Amendments.

(a) The definition of “Excess Securities” is hereby amended and restated in its entirety as follows:

“Excess Securities” means such number of Voting Securities representing the amount of Voting Power, if any, by which the Voting Power represented by Voting Securities beneficially owned, in the aggregate, by all LD Investors and their respective Affiliates and any Person that is a member

of a group with any such Persons with respect to Company Securities exceeds (y) in the case of the Company, 18.5% of the Total Voting Power and (z) in the case of Pubco, 16.02% of the Total Voting Power. For the purposes of the definition of “Excess Securities,” Mammoth and its Affiliates shall not under any circumstances constitute part of a “group” with the LD Investors or any of their Affiliates.

(b) The fourth sentence of Section 6.03 is hereby amended and restated in its entirety as follows:

For the avoidance of doubt, the parties acknowledge and agree that it is intended that each of the Company (or Pubco, as applicable) and Mammoth are separate beneficiaries of all the LD Investors’ obligations under this Agreement and, accordingly, each of the Company (or Pubco, as applicable) and Mammoth shall be separately entitled to bring an action seeking an injunction to prevent breaches of, or enforce compliance with, such obligations, and any waiver of such obligations shall require the written waiver of each of the Company (or Pubco, as applicable) and Mammoth separately; provided that if Mammoth (together with its Affiliates) ceases to beneficially own at least 5,000,000 Common Shares (adjusted for any stock split, stock dividend, reverse stock split or similar event), Mammoth shall no longer be entitled to enforce, or be required to waive or to consent to any waiver by the Company (or Pubco, as applicable) of, such obligations of the LD Investors.

Termination. With respect to the Company, this Agreement shall automatically terminate, without any further action by any Person, upon (i) the written agreement of each party hereto to terminate this Agreement or (ii) the occurrence of any Change of Control Transaction resulting in the creation of a New Company pursuant to clause (a) of the definition thereof. With respect to Pubco, this Agreement shall automatically terminate upon the termination of the Pubco IRA.

4. M. Any and all references to M shall be deemed deleted and nonexistent for any and all purposes under the Agreement and, for the avoidance of doubt, as of the date hereof, M shall not be a party to the Agreement thereto.

5. Investor Board Designees. Solely with respect to Pubco, LGEC hereby agrees that, for so long as any Investor has the right to nominate at least one Investor Designee, LGEC shall, and shall cause each of its Controlled Persons to, (i) cause the Voting Securities of Pubco beneficially owned by LGEC and/or any of its Controlled Persons to be voted in favor of all Investor Designees of any Investor and (ii) not vote any of the Voting Securities beneficially owned by LGEC and/or any of its Controlled Persons in favor of the removal of any Investor Designee of any Investor; provided that, if an Investor entitled to nominate any such director shall request in writing the removal of such director, LGEC shall, and shall cause each of its Controlled Persons to, vote the Voting Securities beneficially owned by LGEC and/or any of its Controlled Persons in favor of such removal.

6. No Other Changes. All terms of the Agreement, except as amended by this Amendment, remain in full force and effect.
