(c) each option to purchase PMG Common Stock issued under any stock option or incentive compensation plan or arrangement of PMG that is outstanding immediately prior to the Effective Time, whether or not then vested or exercisable, shall be converted into an option to purchase the same number of shares of Holdings Common Stock, on substantially the same terms and conditions (including, without limitation, vesting schedule and per share exercise price) as applied to such PMG option; and

(d) the capital stock of Holdings owned by the Surviving Corporation shall be cancelled without payment therefor.

4. Certificates.

6. Bylaws. The Bylaws of PMG as in effect as of the Effective Time shall be the Bylaws of the Surviving Corporation and shall continue in full force and effect until changed, altered or amended as therein provided in the manner prescribed by the laws of the State of Florida.

9. Assumption of Registered Stock Plans and Other Agreements. Holdings and PMG hereby agree that they will, at or prior to the Effective Time, execute, acknowledge and deliver an assumption agreement pursuant to which Holdings will, from and after the Effective Time, assume and agree to perform all outstanding obligations of PMG pursuant to (i) PMG’s stock option plans, incentive compensation plans, employee stock purchase plans and other benefit plans pursuant to which PMG Common Stock is issuable (collectively, the “Stock Plans”); (ii) each stock option agreement, restricted stock agreement and/or similar award agreement entered into pursuant to the Stock Plans; and (iii) any other agreements that management of PMG deems necessary or appropriate to be assumed by Holdings (“Other Agreements”).

The outstanding options and other awards assumed by Holdings shall be exercisable and/or settled upon the same terms and conditions as under the Stock Plans immediately prior to the Effective Time, except that, upon the exercise of each such option or settlement of such award, shares of Holdings Common Stock shall be issuable in lieu of shares of PMG Common Stock issuable with respect thereto immediately prior to the Effective Time.

PMG and Holdings shall take or cause to be taken all actions necessary or desirable for Holdings to assume and perform the obligations of PMG under the Stock Plans and Other Agreements, all to the extent deemed appropriate by PMG and Holdings and permitted under applicable law.

10. Post-Effective Amendments. It is the intent of the parties hereto that Holdings, as of the Effective Time, be deemed a “successor issuer” of PMG for purposes of continuous offerings under the Securities Act of 1933, as amended. As soon as practicable following the Merger, Holdings will, to the extent deemed appropriate, file post-effective amendments to PMG’s registration statements on Form S-8 covering the Stock Plans, adopting such statements as its own registration statements for all purposes of the Securities Act and the Exchange Act and setting forth any additional information necessary to reflect any material changes made in connection with or resulting from the succession, or necessary to keep the registration statements from being misleading.

11. Reservation of Shares. On or prior to the Effective Time, Holdings will reserve sufficient shares of Holdings Common Stock to provide for the issuance of shares of Holdings Common Stock with respect to awards outstanding under the Stock Plans.

12. Employee Benefit Plans. PMG and Holdings will take or cause to be taken all actions necessary or desirable in order for Holdings to assume (or become a participating employer in) each existing employee benefit plan and agreement of PMG, with or without amendments, or to adopt, comparable plans, all to the extent deemed appropriate by PMG and Holdings and permitted under applicable law.

13. Additional Actions. Subject to the terms of this Agreement, the parties hereto shall take all such reasonable and lawful action as may be necessary or appropriate in order to effectuate the Merger. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of Merger Sub or PMG acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of each of Merger Sub and PMG, all such deeds, bills of sale, assignments and assurances and to take and do, in the name and on behalf of each of Merger Sub and PMG or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

14. Termination. This Agreement may be terminated and the Merger contemplated hereby may be abandoned at any time prior to the Effective Time by action of the Board of Directors of PMG, Holdings or Merger Sub if any such Board of Directors should determine that for any reason the completion of the transactions provided for herein would be inadvisable or not in the best interest of such corporation or its shareholders. In the event of such termination and abandonment, this Agreement shall become void and neither PMG, Holdings or Merger Sub nor their respective shareholders, directors or officers shall have any liability with respect to such termination and abandonment.

15. Amendment. This Agreement may be supplemented, amended or modified by the mutual consent of the Boards of Directors of the parties to this Agreement.

16. Governing Law. This Agreement shall be governed by and construed and enforced under the laws of the State of Florida.

17. Counterparts. This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed to be an original but all of which shall constitute one and the same agreement.
