On May 6, 2025, WBD and DLI entered into an investor rights agreement (the "Investor Rights Agreement") with the Issuer, Liberty Parent, Liberty, MHR Fund Management and affiliates of MHR Fund Management. The Investor Rights Agreement provides that (1) for so long as funds affiliated with MHR Fund Management beneficially own at least 10,000,000 Common Shares (prior to the Reverse Stock Split and as adjusted for any stock split, stock dividend, reverse stock split or similar event) in the aggregate, the Issuer will include three designees of MHR Fund Management (at least one of whom will be an independent director and will be subject to Board approval) on its slate of director nominees for election at each future annual meeting of the Issuer's shareholders, (2) for so long as funds affiliated with MHR Fund Management beneficially own at least 7,500,000, but less than 10,000,000, Common Shares (prior to the Reverse Stock Split and as adjusted for any stock split, stock dividend, reverse stock split or similar event) in the aggregate, the Issuer will include two designees of MHR Fund Management on its slate of director nominees for election at each future annual meeting of the Issuer's shareholders and (3) for so long as funds affiliated with MHR Fund Management beneficially own at least 5,000,000, but less than 7,500,000, Common Shares (prior to the Reverse Stock Split and as adjusted for any stock split, stock dividend, reverse stock split or similar event) in the aggregate, the Issuer will include one designee of MHR Fund Management on its slate of director nominees for election at each future annual meeting of the Issuer's shareholders.

In addition, the Investor Rights Agreement provides that (1) for so long as Liberty Parent and WBD (together with certain of their affiliates) beneficially own at least 10,000,000 Common Shares (prior to the Reverse Stock Split and as adjusted for any stock split, stock dividend, reverse stock split or similar event) in the aggregate, the Issuer will include one designee of Liberty Parent and one designee of WBD on its slate of director nominees for election at each future annual meeting of the Issuer's shareholders and (2) for so long as Liberty Parent and WBD (together with certain of their affiliates) beneficially own at least 5,000,000, but less than 10,000,000, Common Shares (prior to the Reverse Stock Split and as adjusted for any stock split, stock dividend, reverse stock split or similar event) in the aggregate, the Issuer will include one designee of Liberty Parent and WBD, collectively, on its slate of director nominees for election at each future annual meeting of the Issuer's shareholders, selected by (a) Liberty Parent, if Liberty Parent (together with certain of its affiliates) individually exceeds such 5,000,000 Common Shares threshold but WBD (together with certain of its affiliates) does not, (b) WBD, if WBD (together with certain of its affiliates) individually exceeds such 5,000,000 Common Shares threshold but Liberty Parent (together with certain of its affiliates) does not and (c) Liberty Parent and WBD, jointly, if neither Liberty Parent nor WBD (together with certain of their affiliates) individually exceeds such 5,000,000 Common Shares threshold.

Under the Investor Rights Agreement, Liberty Parent and WBD (together with certain of their affiliates) have agreed that if they sell or transfer any of their Common Shares to a shareholder or group of shareholders that beneficially own 5% or more of the Common Shares, or that would result in a person or group of persons beneficially owning 5% or more of the Common Shares, any such transferee would have to agree to the transfer and voting provisions set forth in the Investor Rights Agreement, subject to certain exceptions set forth in the Investor Rights Agreement. The Issuer has also agreed to provide Liberty Parent, WBD and MHR Fund Management with certain pre-emptive rights on Common Shares that the Issuer may issue in the future for cash consideration. Upon execution of the Investor Rights Agreement, the existing Investor Rights Agreement, dated as of November 10, 2015 and as amended from time to time, was automatically terminated and of no further force or effect.

Voting Agreement. On May 6, 2025, WBD and DLI entered into a voting agreement with the Issuer, Liberty Parent, Liberty, MHR Fund Management and certain affiliates of MHR Fund Management (the "Voting Agreement"). Under the Voting Agreement, Liberty Parent and WBD have agreed to vote, in any vote of the Issuer's shareholders on a merger, amalgamation, plan of arrangement, consolidation, business combination, third party tender offer, asset sale or other similar transaction involving the Issuer or any of the Issuer's subsidiaries (and any proposal relating to the issuance of capital, increase in the authorized capital or, subject to certain exceptions, any amendment to any constitutional documents in connection with any of the foregoing), all of the Common Shares beneficially owned by them (together with certain of their affiliates) in excess of 18.5% of the Issuer's outstanding voting power in the aggregate in the same proportion as the votes cast by shareholders other than Liberty Parent and WBD (together with certain of their affiliates). Although the Common Shares beneficially owned by each of DLI and Liberty will be aggregated for purposes of determining compliance with such ownership restrictions, the Reporting Persons do not have any agreement with Liberty regarding such limitation. In addition, each of Liberty Parent, WBD and MHR Fund Management (together with certain of their affiliates) has agreed that as long as any of them have the right to nominate at least one representative to the Board, each of them will vote all of Common Shares owned by them (together with certain of their affiliates) in favor of each of the other's respective director nominees, subject to certain exceptions set forth in the Voting Agreement. Under the Voting Agreement, Liberty Parent and WBD (together with certain of their affiliates) have also agreed that if they sell or transfer any of their Common Shares to a shareholder or group of shareholders that beneficially own 5% or more of the Common Shares, or that would result in a person or group of persons beneficially owning 5% or more of the Common Shares, any such transferee would have to agree to the transfer and voting provisions set forth in the Voting Agreement, subject to certain exceptions set forth in the Voting Agreement. Upon execution of the Voting Agreement, the existing Voting and Standstill Agreement, dated as of November 10, 2015 and as amended from time to time, was automatically terminated and of no further force or effect. The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Voting Agreement, which is attached hereto as Exhibit 99.13 and incorporated herein by reference. Registration Rights Agreement. On May 6, 2025, DLI entered into a registration rights agreements with the Issuer (the "Registration Rights Agreement"), which provides DLI (together with certain of their affiliates) with certain registration rights, subject to the terms and conditions set forth therein. Among other things, DLI will be entitled to two demand registration rights to request that the Issuer register all or a portion of its Common Shares. In addition, in the event that the Issuer proposes to register any of the Issuer's equity securities or securities convertible into or exchangeable for the Issuer's equity securities, either for the Issuer's own account or for the account of other security holders, DLI will be entitled to certain "piggyback" registration rights allowing them to include their shares in such registration, subject to customary limitations. As a result, whenever the Issuer proposes to file a registration statement under the Securities Act of 1933, as amended, other than with respect to a registration statement on Forms S-4 or S-8 or certain other exceptions, DLI will be entitled to notice of the registration and have the right, subject to certain limitations, to include their shares in the registration. The registration rights described above will terminate on the first anniversary of the date that DLI (together with certain of its affiliates) both (i) beneficially owns less than 334,436 Common Shares, subject to equitable adjustment (which amount, for the avoidance of doubt, represents approximately 2% of the Common Shares outstanding as of May 7, 2025), and (ii) ceases to have a designated representative on the Board. Liberty has entered into a similar registration rights agreement with the Issuer. Upon execution of the Registration Rights Agreement, the existing Registration Rights Agreement, dated as of November 10, 2015, was automatically terminated and of no further force or effect. The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement, which is attached hereto as Exhibit 99.14 and incorporated herein by reference.
