(b)           In furtherance of the foregoing, each Stockholder hereby irrevocably grants to, and appoints, until the termination of this Agreement in accordance with Section 2.1, Navy, each of Navy’s officers and any person or persons designated in writing by Navy, and each of them individually, as such Stockholder’s proxy and attorney-in-fact (with full power of substitution and resubstitution), for and in the name, place and stead of such Stockholder, to vote or grant a written consent in respect of all of such Stockholder’s Subject Shares, or execute and deliver a proxy to vote or grant a written consent in respect of the Subject Shares, on the matters and in the manner specified in Section 1.1(a) of this Agreement.  Each Stockholder hereby affirms that such irrevocable proxy is given in connection with, and in consideration of, the execution of the Merger Agreement by Navy, Red Lion and Penny, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement.  Each Stockholder hereby further affirms that such proxy is irrevocable and is coupled with an interest sufficient in law to support an irrevocable power and may under no circumstances be revoked.  Such proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212 of the DGCL until the termination of this Agreement in accordance with Section 2.1.  Each Stockholder shall execute any further agreement or form reasonably necessary or appropriate to confirm and effectuate the grant of the proxy contemplated herein.  Each Stockholder hereby revokes (or causes to be revoked) any and all previous proxies, powers of attorney, instructions or other requests with respect to such Stockholder’s Subject Shares.  Navy may terminate this proxy with respect to each Stockholder at any time at its sole election by written notice provided to such Stockholder.

Section 1.2            No Transfers; No Inconsistent Arrangements.  Except as provided hereunder, each Stockholder agrees not to, directly or indirectly, (i) transfer (which term shall include any sale, assignment, gift, pledge, hypothecation or other disposition), or consent to, agree to or permit any such transfer of, any or all of the Subject Shares or any interest therein (except for a transfer for estate or tax planning purposes, for charitable purposes or as charitable gifts or donations where the transferee or third party agrees in writing to be bound by the terms hereof), or create or permit to exist any Liens, proxies, voting trusts or agreements, options, rights, understandings or arrangements or any other encumbrances whatsoever on title, transfer,

2

or exercise of any rights of a stockholder in respect of such Subject Shares (collectively, “Encumbrances”) that would prevent such Stockholder from voting the Subject Shares in accordance with this Agreement or from complying with its other obligations under this Agreement, other than any restrictions imposed by applicable law on any such Subject Shares; (ii) enter into any contract, option or other agreement, arrangement or understanding inconsistent with the terms of this Agreement with respect to any transfer of Subject Shares or any interest therein; (iii) grant or permit the grant of any proxy, power of attorney or other authorization in or with respect to the Subject Shares relating to the subject matter hereof; (iv) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares; or (v) take or permit any other action that would in any way restrict, limit or interfere with the performance of its obligations hereunder or the transactions contemplated hereby (any of the actions set forth in clauses (i) through (v) above, and any conversion, exchange or other disposition of the Subject Shares in a transaction related to an Acquisition Proposal being referred to in this Agreement as a “Transfer”).  Any action taken in violation of the foregoing sentence shall be null and void ab initio.  To the extent the a Stockholder’s Subject Shares are represented by certificates, such Stockholder shall make available to Penny such certificates in order for Penny to mark such certificates with legends required by the DGCL regarding the foregoing Transfer restrictions.  If any involuntary Transfer of any of the Subject Shares shall occur, the transferee (which term, as used herein, shall include the initial transferee and any and all subsequent transferees of the initial transferee) shall take and hold such Subject Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until the valid termination of this Agreement.
