Annex D

     SECTION 5.2 NO SOLICITATION

     (a) During the period beginning on November 13, 2006 (the “Commencement Date”) and continuing until 12:01 a.m. Central Time on December 13, 2006 (the “Go-Shop Period”), the Company and its officers, directors, employees, agents and representatives, including any investment banker, attorney or accountant retained by the Company, shall have the right to: (i) initiate, solicit and encourage Acquisition Proposals, including by way of providing access to non-public information to any other Person pursuant to a confidentiality agreement in reasonably customary form and which does not contain terms that prevent the Company from complying with its obligations under this Section 5.2; provided that the Company shall promptly provide to Parent any material non-public information concerning the Company or its Subsidiaries that is provided to any Person given such access which was not previously provided to Parent; and (ii) enter into and maintain or continue discussions or negotiations with respect to Acquisition Proposals or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations.

     (b) Subject to Section 5.2(c) and except as may relate to any Person or group of related Persons from whom the Company has received, after the Commencement Date and prior to the expiration of the Go-Shop Period, a bona fide written Acquisition Proposal that the board of directors of the Company believes in good faith, after consultation with its outside legal counsel, constitutes or could reasonably be expected to lead to a Superior Proposal (any such Person or group of related Persons, an “Identified Party”), the Company shall, and the Company shall cause its officers, directors, employees, agents or representatives, including any investment banker, attorney or accountant retained by the Company, from and after the expiration of the Go-Shop Period to (i) immediately cease and cause to be terminated any existing discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal; and (ii) until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article 7, not solicit, initiate or encourage (including by way of furnishing non-public information) any inquiry, proposal or offer (including any proposal or offer to its stockholders) with respect to a third-party tender offer, merger, consolidation, business combination, sale of assets, sale of stock or joint venture or similar transaction involving any assets or class of capital stock of the Company, or any acquisition of the capital stock of the Company or a business or material assets (other than sales of current assets in the ordinary course of business) of the Company in a single transaction or a series of related transactions, or any combination of the foregoing (any such proposal, offer or transaction being hereinafter referred to as an “Acquisition Proposal”) or engage in any discussions or negotiations concerning an Acquisition Proposal.

     (c) Notwithstanding anything to the contrary in Section 5.2(b) but subject to the last sentence of this Section 5.2(c), at any time following the expiration of the Go-Shop Period and prior to obtaining the Requisite Vote, in response to a bona fide written Acquisition Proposal (which must be unsolicited except to the extent made in response to a solicitation made during the Go-Shop Period) made after the expiration of the Go-Shop Period, nothing contained in this Agreement shall prevent the Company or its board of directors from providing information (pursuant to a confidentiality agreement in reasonably customary form and which does not

contain terms that prevent the Company from complying with its obligations under this Section 5.2) to or engaging in any negotiations or discussions with any Person or group who has made a bona fide Acquisition Proposal with respect to all of the outstanding shares of capital stock of the Company or all or substantially all of the assets of the Company if (x) the Company’s board of directors determines in good faith and after consultation with its financial advisors, taking into account all financial considerations, including the legal, financial, regulatory and other aspects of the Acquisition Proposal deemed relevant by the Company’s board of directors, the identity of the Person making the Acquisition Proposal, and the conditions and prospects for completing the Acquisition Proposal, that such Acquisition Proposal is reasonably likely to result in a transaction more favorable to the holders of the Shares from a financial point of view than the Merger (a “Superior Proposal”) and (y) the board of directors of the Company, after consultation with its outside legal counsel, determines in good faith that the failure to do so would result in a breach of its fiduciary obligations under applicable law. Notwithstanding the foregoing, the parties agree that, notwithstanding the expiration of the Go-Shop Period, the Company may continue to engage in the activities described in Section 5.2(a)(i) and (ii) with respect to any Identified Parties, including with respect to any amended proposal submitted by such Identified Parties following the expiration of the Go-Shop Period.

     (d) As of the expiration of the Go-Shop Period, the Company shall advise Parent of the identities of Identified Parties and the material terms and conditions of each Acquisition Proposal received from an Identified Party. Following the expiration of the Go-Shop Period, the Company agrees that it will notify Parent promptly (and in any event within 24 hours) if any proposal or offer relating to or constituting an Acquisition Proposal is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company or any of its officers, directors, employees, agents or representatives. In connection with such notice, the Company shall indicate the identity of the Person or group making such request or inquiry or engaging in such negotiations or discussions and the material terms and conditions of any Acquisition Proposal. Thereafter, the Company shall keep Parent fully informed on a prompt basis (and in any event within 24 hours) of any material changes, additions or adjustments to the terms of any such proposal or offer. Prior to taking any action referred to in Section 5.2(c), if the Company intends to participate in any such discussions or negotiations or provide any such information to any such third party, the Company shall give prior written notice to Parent.

     (e) Subject to Section 7.3(b), nothing contained in this Agreement shall prevent the Company or its board of directors from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act or making any disclosure to the Company’s stockholders if the Company’s board of directors determines in good faith that the failure to make such disclosure would result in a breach of its fiduciary duties under applicable law.

Annex E

From the date hereof to the Effective Time, and except as set forth in Schedule 5.5 of the Disclosure Letter, the Company shall allow all designated officers, attorneys, accountants and other representatives of Parent access at all reasonable times upon reasonable notice to the records and files, correspondence, audits and properties, as well as to all information relating to commitments, contracts, titles and financial position, or otherwise pertaining to the business and affairs of the Company and its Subsidiaries, including inspection of such properties; provided that no investigation by Parent pursuant to this Section 5.5 shall affect any representation or warranty given by the Company hereunder, and provided further that notwithstanding the provision of information by the Company or investigation by Parent, the Company shall not be deemed to make any representation or warranty except as expressly set forth in this Agreement.
