1.5 Disclosure of Information. Each Shareholder hereby (a) consents to and authorizes the publication and disclosure by GLPI or Pinnacle of such person’s identity and record or beneficial ownership of Subject Shares, the nature of such Shareholder’s commitments, arrangements and understandings under this Agreement and any other information, in each case, to the extent it is required to be disclosed by applicable Law in any press release, proxy statement, information statement, registration statement or any other disclosure document in connection with the Merger and the transactions contemplated by the Merger Agreement; and (b) agrees promptly to provide GLPI and Pinnacle with any information that in the reasonable determination of GLPI or Pinnacle is required for inclusion in any such disclosure documents (provided that the foregoing shall not require such Shareholder to disclose (i) any information, that in its reasonable judgment, would result in the disclosure of any trade secrets of third parties

3

or violate any of its confidentiality obligations owed to third parties; or (ii) any information that would, in its reasonable judgment, waive the protection of attorney-client privilege if the Shareholder shall have used reasonable best efforts to disclose such information in a way that would not waive such privilege). Each Shareholder agrees to use commercially reasonable efforts to promptly notify Pinnacle and GLPI in writing of any required corrections with respect to any information supplied by such person specifically for use in any such disclosure document, if and to the extent that any such information shall have become false or misleading in any material respect.

1.6 Irrevocable Proxy. Each Shareholder hereby revokes any and all prior proxies (other than this Agreement) given by such Shareholder with respect to its Subject Shares with respect to any of the Section 1.1(b) Matters and hereby irrevocably appoints Pinnacle as attorney-in-fact (with full power of substitution) and proxy for and on behalf of such Shareholder, for and in the name, place and stead of such Shareholder, to: (a) attend any and all GLPI Shareholders Meetings; and (b) vote or issue instructions to the record holder to vote such Subject Shares in accordance with the provisions of Section 1.1 in connection with any such GLPI Shareholders Meeting; provided, however, that (i) such Shareholder’s grant of the proxy contemplated hereby shall be effective if, and only if, such Shareholder has not delivered to the Secretary of GLPI at least ten (10) business days prior to such meeting a duly executed proxy card, previously approved by Pinnacle, voting the Subject Shares in the manner specified in Section 1.1 or in the event such proxy card has been thereafter modified or revoked or otherwise fails to provide evidence of such Shareholder’s compliance with its obligations under Section 1.1 in form and substance reasonably acceptable to Pinnacle; and (ii) such Shareholder hereby affirms that (A) the irrevocable proxy set forth in this Section 1.6, if it becomes effective pursuant to clause (i), is given in connection with the execution of the Merger Agreement and as an inducement to Pinnacle to enter into the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Shareholder under this Agreement; and (B) this irrevocable proxy is coupled with an interest; and (C) such irrevocable proxy, if it becomes effective pursuant to clause (i), is executed and intended to be irrevocable pursuant to the provisions of Title 15 (Corporations and Unincorporated Associations), Section 1759(d) of the Pennsylvania Code. Pinnacle (or its designee) agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this Agreement. Except to the extent of any Subject Shares acquired, directly or indirectly, after the date hereof (which, for clarity, shall become Subject Shares upon that acquisition), the number of Shares owned by the Shareholders referenced above are the only Shares owned beneficially or of record by the Shareholders as of the date of this Agreement. The proxy granted by each Shareholder in this Section 1.6 shall remain valid until the earlier of (i) the time that the Parent Shareholder Approval has been obtained or (ii) the termination of this Agreement in accordance with Section 4.2, in each case immediately upon which each such proxy shall automatically terminate without any further action required by any person.

Each Shareholder shall promptly (and in any event two (2) business days notify Pinnacle in writing of (a) the number of Shares, if any, as to which such Shareholder acquires record or beneficial ownership after the date hereof (which, for the avoidance of doubt, shall be Subject Shares).

1.8 Further Assurances. Each party agrees to execute and deliver, or cause to be executed and delivered, all further documents and instruments as the other party shall reasonably request and use commercially reasonable efforts to take, or cause to be taken, all reasonably necessary actions, consistent with applicable Laws and regulations, to perform, in a timely expeditious manner, their respective obligations under this Agreement.

1.9 Notices of Certain Events.
