2.    Agreement to Not Transfer the Covered Shares.

2.1    No Transfer of Covered Shares. Until the Expiration Time, each Stockholder agrees not to Transfer or cause or permit the Transfer of any of such Stockholder’s Covered Shares, other than (i) with the prior written consent of Parent (to be granted or withheld in Parent’s sole discretion) or (ii) with respect to the Covered Shares set forth on Schedule A hereto, pursuant to and as currently required by pledge arrangements with a third party banking institution in existence as of the date of this Agreement. Any Transfer or attempted Transfer of any Covered Shares in violation of this Section 2.1 shall be null and void and of no effect whatsoever; provided, however, that any Stockholder may Transfer any such Covered Shares to (i) any other Stockholder or any Affiliate of any such Stockholder, (ii) any family member (including a trust for such family member’s benefit) of such Stockholder or (iii) any charitable foundation or organization, in each case only if the transferee of such Covered Shares evidences in a writing reasonably satisfactory to Parent such transferee’s agreement to be bound by and subject to the terms and provisions hereof to the same effect as such transferring Stockholder; provided, however, that notwithstanding anything to the contrary herein, Stockholders shall be permitted to Transfer by gift an aggregate of not more than 600,000 Covered Shares to any charitable foundations or organizations without any restrictions hereunder; provided further, that any such Transfers after the date hereof by any Stockholder to the Zell Family Foundation shall not be deemed to be Covered Shares and shall not be subject to the terms and conditions of this Agreement.

2.2    Update of Beneficial Ownership Information.

Each

-2-

Stockholder agrees to cause any of its Affiliates that acquires any shares of Common Stock on or after the date hereof to execute an agreement in a form reasonably acceptable to Parent to be bound with respect to this Agreement with respect to such shares to the same extent such shares would be subject to this Agreement had they been acquired by such Stockholder.

3.    Agreement to Vote the Covered Shares.

3.1    Until the Expiration Time, at every meeting of the Company’s stockholders at which any of the following matters are to be voted on (and at every adjournment or postponement thereof), and on any action or approval of Company’s stockholders by written consent with respect to any of the following matters, each Stockholder shall vote (including via proxy) all of such Stockholder’s Covered Shares (or cause the holder of record on any applicable record date to vote (including via proxy) all of such Stockholder’s Covered Shares):

(a)    in favor of the adoption of the Merger Agreement; and

(b)    against (A) any action or agreement that would reasonably be expected to result in a breach of the Merger Agreement or result in any condition set forth in Article VII of the Merger Agreement not being satisfied on a timely basis, (B) any Company Takeover Proposal, or any other proposal made in opposition to, in competition with, or inconsistent with the Merger Agreement, the Merger or the transactions contemplated by the Merger Agreement and (C) any other action, agreement or proposal which could reasonably be expected to delay, postpone or adversely affect consummation of the Merger and the other transactions contemplated by the Merger Agreement.

3.2    Until the Expiration Time, at every meeting of the Company’s stockholders (and at every adjournment or postponement thereof), each Stockholder shall be represented in person or by proxy at such meeting (or cause the holders of record on any applicable record date to be represented in person or by proxy at such meeting) in order for the Covered Shares to be counted as present for purposes of establishing a quorum.

3.4    Notwithstanding anything to the contrary in this Agreement, if at any time following the date hereof and prior to the Expiration Time, a Governmental Entity enters an order restraining, enjoining or otherwise prohibiting the Stockholders or their Affiliates from taking any action pursuant to Section 3.1, Section 3.2 or Section 3.3 of this Agreement, then (i) the obligations of each Stockholder set forth in Section 3.1, Section 3.2 or Section 3.3 of this Agreement shall be of no force and effect for so long as such order is in effect solely to the extent such order restrains, enjoins or otherwise prohibits such Stockholder from taking any such action, and (ii) each Stockholder shall cause the Covered Shares to not be represented in person or by proxy at any meeting at which a vote of such Stockholder on the Merger Agreement or the transactions contemplated thereby is sought or requested.

-3-

3.5    Without limiting the obligations of the Stockholders under this Agreement, but only in the event and in each case that such Stockholder fails to be counted as present or fails to vote all of such Stockholder’s Covered Shares in accordance with this Agreement or except as provided in Section 3.4 above, then in such event each Stockholder hereby irrevocably appoints as its proxy and attorney-in-fact the officers of Parent, and any individual who shall hereafter succeed to any such officer of Parent, and any other Person designated in writing by Parent (collectively, the “Proxy Holders”), each of them individually, with full power of substitution, to vote such Stockholder’s Covered Shares in accordance with this Agreement and, in the discretion of the Proxy Holders, with respect to any proposed postponements or adjournments of meetings of the Company’s stockholders at which any of the matters described in this Agreement are to be considered. This proxy is coupled with an interest and shall be irrevocable, and each Stockholder shall take such further action or execute such other instruments as may be reasonably necessary to effectuate the intent of this proxy and hereby revokes any proxy previously granted by such Stockholder with respect to such Stockholder’s Covered Shares. Notwithstanding anything to the contrary in this Agreement, the proxy granted by this Section 3.4 shall terminate and be of no further force and effect upon the Expiration Time.

4.    Waiver of Appraisal Rights. Each Stockholder hereby waives all appraisal rights under Section 262 of the DGCL with respect to all of such Stockholder’s Covered Shares owned (beneficially or of record) by such Stockholder.

In addition, each Stockholder (solely in the capacity as a stockholder of the Company) agrees to be subject to Section 5.03 of the Merger Agreement as if each were the “Company” thereunder (including with respect to the obligations to notify Parent promptly, and in any event within 24 hours of receipt, in writing of any Company Takeover Proposal or any inquiry with respect to, or that could reasonably be expected to lead to, any Company Takeover Proposal and the identity of the Person or group of Persons making such Company Takeover Proposal or inquiry and to provide unredacted copies of all material correspondence and proposed transaction documents, including any financing documents, received by such Stockholder in connection with such Company Takeover Proposal or inquiry, or, if communicated orally, a summary of the material terms of such oral communication, and to otherwise keep Parent informed on a current basis of the status of any such Company Takeover Proposal or inquiry, including any material developments or change to the material terms thereof).

5.2    Notwithstanding the foregoing, from and after the date of the Merger Agreement until the Expiration Time and if the Company is permitted, pursuant to Sections 5.03(b)

-4-

or 5.03(c) of the Merger Agreement, to have discussions or negotiations in response to a Company Takeover Proposal that did not result from a breach (other than a breach that is immaterial and unintentional) of Section 5.03(b) of the Merger Agreement, each Stockholder and its Representatives shall be permitted to participate in such discussions or negotiations with such person making such Company Takeover Proposal, to the same extent as the Company is permitted to do so under Sections 5.03(b) or 5.03(c) of the Merger Agreement, subject to compliance by such Stockholder with the last sentence of Section 5.1 above.

6.    No Legal Action. Each Stockholder shall not, and shall cause its Representatives not to, bring, commence, institute, maintain, prosecute or voluntarily aid any claim, appeal, or proceeding which (a) challenges the validity of or seeks to enjoin the operation of any provision of this Agreement or (b) alleges that the execution and delivery of this Agreement by any of the Stockholders (or their performance hereunder solely in the capacity as a stockholder of the Company) breaches any fiduciary duty of the Company Board (or any member thereof) or any duty that any of the Stockholders have (or may be alleged to have) to the Company or to the other holders of the Common Stock.

7.    Fiduciary Duties. Each Stockholder is entering into this Agreement solely in its capacity as the record holder or beneficial owner of such Stockholder’s Covered Shares. Nothing in this Agreement shall in any way, or shall require any Stockholder to attempt to limit or affect any actions taken by any of Stockholder’s designee(s) serving on the Company Board or any such Stockholder in his or her capacity as a director, officer or employee of the Company or any of its Affiliates, from complying with his or her fiduciary obligations while acting in such designee’s capacity as a director of the Company. No action taken (or omitted to be taken) in any such capacity as director, officer or employee shall be deemed to constitute a breach of this Agreement.

8.    Notice of Certain Events. Each Stockholder shall notify Parent in writing promptly of (a) any fact, event or circumstance that would cause, or reasonably be expected to cause or constitute, a breach of the representations and warranties of such Stockholder under this Agreement or (b) the receipt by such Stockholder of any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with this Agreement.

As of the date hereof, there is no event of default (or event that with notice or lapse of time or both would become a default) under any such pledge arrangements.

(c)    EACH OF THE PARTIES HERETO HEREBY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ALL RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY OR THE FACTS OR CIRCUMSTANCES LEADING TO ITS EXECUTION OR PERFORMANCE. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO PARTY OR REPRESENTATIVE OR AFFILIATE THEREOF HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVER, (iii) IT MAKES SUCH WAIVER KNOWINGLY AND VOLUNTARILY AND (iv) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS PARAGRAPH.

Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limiting the generality of the foregoing”. When used in this Agreement, the term “or” shall be construed in the inclusive sense of “and/or”. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. References to a Person are also to its permitted successors and assigns.

11.14    Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties.

Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

11.15    Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

-11-

11.18    Non-survival of Representations and Warranties. None of the representations and warranties in this Agreement or in any schedule, instrument or other document delivered pursuant to this Agreement shall survive the Effective Time or the termination of this Agreement. This Section 11.18 shall not limit any covenant or agreement contained in this Agreement that by its terms is to be performed in whole or in part after the Effective Time or the termination of this Agreement.

11.19    Termination. This Agreement shall automatically terminate without further action by any of the parties hereto and shall have no further force or effect as of the earliest to occur of (i) the Expiration Time or (ii) with respect to any Stockholder, the election of such Stockholder in its sole discretion to terminate this Agreement promptly following any amendment of any term or provision of the original unamended Merger Agreement dated as of the date hereof that reduces or changes the form of consideration payable pursuant to such Merger Agreement; provided that the provisions of this Article XI shall survive any such termination. Notwithstanding the foregoing, termination of this Agreement shall not prevent any party from seeking any remedies (at law or in equity) against any other party for that party’s breach of any of the terms of this Agreement prior to the date of termination.
