(iv) against any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by the Company,

(v) against any change in the business, management or Board of Directors of the Company (other than in connection with the transactions described in clause (i) above) and

Stockholder shall not commit or agree to take any action inconsistent with the foregoing.

(b) Irrevocable Proxy. Concurrently with the execution of this Agreement, each Stockholder agrees to execute and deliver to Parent an irrevocable proxy in the form attached as Exhibit A hereto (subject to the proviso to this sentence, each a “Proxy” and, collectively, the “Proxies”), which shall be irrevocable to the extent permitted by applicable law, covering all Covered Shares; provided, however, that, in the event that, the number of Covered Shares are modified, including due to the acquisition of Additional Owned Shares, each Stockholder may (and, promptly upon any request by Parent, shall) execute and deliver to Parent an irrevocable proxy in the form attached as Exhibit A hereto, except that the definition of “Covered Shares” therein will be updated accordingly, and, upon delivery of such new proxy to Parent, Parent will destroy the existing Proxy and such new proxy will be deemed the Proxy for the purposes of this Agreement. Each Stockholder hereby represents to Parent that any proxies heretofore given in respect of the Covered Shares are not irrevocable and that any such proxies are hereby revoked, and each Stockholder agrees to promptly notify the Company of such revocation. Each Stockholder hereby affirms that the Proxy is given in connection with the execution of the Merger Agreement 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 the Proxy is coupled with an interest and may under no circumstances be revoked. Each Stockholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Without limiting the generality of the foregoing, such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 705(e) of the CGCL. If for any reason the proxy granted herein is not irrevocable, each Stockholder agrees to vote the Covered Shares in accordance with Section 2(a) hereof.

3. No Disposition or Solicitation.

(a) No Disposition or Adverse Act. Each Stockholder hereby covenants and agrees that, except as set forth in Section 3(b) hereof and as otherwise contemplated by this Agreement and the Merger Agreement, such Stockholder shall not (i) offer to Transfer, Transfer or consent to any Transfer of any or all of the Covered Shares or any interest therein without the prior written consent of Parent, (ii) enter into any contract, option or other agreement or understanding with respect to any Transfer of any or all Covered Shares or any interest therein, (iii) grant any proxy, power-of-attorney or other authorization or consent in or with respect to any or all of the Covered Shares, (iv) deposit any or all of the Covered Shares into a voting trust or enter into a voting agreement or arrangement with respect to any or all of the Covered Shares or (v) take any other action that would make any representation or warranty of Stockholder contained herein untrue or incorrect or in any way restrict, limit or interfere with the performance of such Stockholder’s obligations hereunder or the transactions contemplated hereby or by the Merger Agreement. Any attempted Transfer of Covered Shares or any interest therein in violation of this Section 3(a) shall be null and void.

(b) Permitted Transfers. Section 3(a) shall not prohibit a Transfer of Covered Shares by Stockholder (i) upon the death of Stockholder, (ii) to any member of Stockholder’s immediate family, or to a trust for the benefit of Stockholder or any member of Stockholder’s immediate family or (iii) to a charitable organization qualified under Section 501(c)(3) of the Internal Revenue Code of 1986, including without limitation The Greenberg Foundation; provided, however, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by the terms of this Agreement and delivers a proxy to Parent in substantially the form of the Proxy.

(c) Non-Solicitation. Subject to Section 7 hereof, each Stockholder hereby agrees that such Stockholder shall not, and shall cause its Affiliates, representatives and agents (including its investment bankers, attorneys and accountants) (collectively, its “Representatives”) not to, directly or indirectly, encourage, solicit, initiate or participate in any way in any discussions or negotiations with, or provide any information to, or afford any access to the properties, books or records of the Company or any of its Subsidiaries to, enter into any agreement with, or otherwise take any other action to assist or facilitate, any person (other than Parent or Merger Sub or any of their respective Representatives) relating to any Acquisition Proposal. Each Stockholder shall immediately cease any existing activities, discussions or negotiations conducted heretofore with respect to any Acquisition Proposal. Each Stockholder shall immediately communicate to Parent the terms of any Acquisition Proposal (or any discussion, negotiation or inquiry with respect thereto) directed to or involving such Stockholder

solely in its capacity as a stockholder of the Company and not as a director or officer of the Company, including the identity of the person making such Acquisition Proposal or inquiry which it may receive. Each Stockholder shall keep Parent fully informed, on a current basis, of the status and terms of any such Acquisition Proposal or inquiry. Any violation of the foregoing restrictions by any Stockholder or any of its Representatives shall be deemed to be a material breach of this Agreement by such Stockholder.

4. Additional Agreements.

(a) Certain Events. In the event of any stock split, stock dividend, merger, reorganization, recapitalization or other change in the capital structure of the Company affecting the Covered Shares or the acquisition of Additional Owned Shares or other securities or rights of the Company by any Stockholder or any of its Affiliates, (i) the type and number of Covered Shares shall be adjusted appropriately and (ii) this Agreement and the obligations hereunder shall automatically attach to any additional Covered Shares or other securities or rights of the Company issued to or acquired by such Stockholder or any of its Affiliates.

(b) Waiver of Appraisal and Dissenters’ Rights and Actions. Each Stockholder hereby (i) waives and agrees not to exercise any rights of appraisal or rights to dissent from the Merger that such Stockholder may have and (ii) agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger, including any claim (x) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or (y) alleging a breach of any fiduciary duty of the Board of Directors of the Company in connection with the Merger Agreement or the transactions contemplated thereby.

(d) Additional Owned Shares. Each Stockholder hereby agrees to notify Parent promptly in writing of the number and description of any Additional Owned Shares.

5. Representations and Warranties of Stockholder. Each Stockholder hereby represents and warrants to Parent as follows:

(a) Title. Such Stockholder is the sole record and beneficial owner of the shares of Company Common Stock set forth opposite such Stockholder’s name on Schedule I (the “Disclosed Owned Shares”). The Disclosed Owned Shares constitute all of the capital stock and any other equity securities of the Company owned of record or beneficially by such Stockholder and its Affiliates on the date hereof and neither such Stockholder nor any of its Affiliates is the beneficial owner of, or has any right to acquire (whether currently, upon lapse of time, following the satisfaction of any conditions, upon the occurrence of any event or any combination of the foregoing) any shares of Company Common Stock or any other equity securities of the Company or any securities convertible into or exchangeable or exercisable for shares of Company Common Stock or such other equity securities, in each case other than the Disclosed Owned Shares. Such Stockholder has sole voting power, sole power of disposition and sole power to issue instructions with respect to the matters set forth in Sections 3 and 4 hereof and all other matters set forth in this Agreement, in each case with respect to all of the Owned Shares with no limitations, qualifications or restrictions on such rights, subject to applicable securities laws and the terms of this Agreement. Except as permitted by this Agreement, the Owned Shares and the certificates representing such shares, if any, are now, and at all times during the term hereof will be, held by such Stockholder, or by a nominee or custodian for the benefit of such Stockholder, free and clear of any and all liens, pledges, claims, options, proxies, voting trusts or agreements, security interests, understandings or arrangements or any other encumbrances whatsoever on title, transfer or exercise of any rights of a stockholder in respect of the Owned Shares (other than as created by this Agreement) (collectively, “Liens”).

(b) Organization and Qualification. If such Stockholder is not a natural person, such Stockholder is a legal organization duly organized and validly existing in good standing under the laws of the jurisdiction of its organization indicated on Schedule I hereto.

(d) Due Execution and Delivery. This Agreement has been duly and validly executed and delivered by such Stockholder and, assuming due authorization, execution and delivery hereof by Parent, constitutes a legal, valid and binding agreement of such Stockholder, enforceable against such Stockholder in accordance with its terms. If such Stockholder is married, and any of the Covered Shares constitute community property or spousal approval is otherwise necessary for this Agreement to be legal, binding and enforceable, this Agreement has been duly authorized, executed and delivered by, and constitutes the legal, valid and binding obligation of, such Stockholder’s spouse, enforceable against such Stockholder’s spouse in accordance with its terms.

(e) No Filings; No Conflict or Default. Except for filings under the HSR Act, any competition, antitrust and investment laws or regulations of foreign jurisdictions and the

Exchange Act, no filing with, and no permit, authorization, consent or approval of, any Governmental Entity or any other person is necessary for the execution and delivery of this Agreement by such Stockholder, the consummation by such Stockholder of the transactions contemplated hereby and the compliance by such Stockholder with the provisions hereof. None of the execution and delivery of this Agreement by such Stockholder, the consummation by such Stockholder of the transactions contemplated hereby or compliance by such Stockholder with any of the provisions hereof will (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, modification or acceleration) under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, lease, license, permit, contract, commitment, arrangement, understanding, agreement or other instrument or obligation of any kind, including any voting agreement, proxy arrangement, pledge agreement, shareholders agreement or voting trust, to which such Stockholder is a party or by which such Stockholder or any of such Stockholder’s properties or assets may be bound, (ii) violate any judgment, order, writ, injunction, decree or award of any court, administrative agency or other Governmental Entity that is applicable to such Stockholder or any of such Stockholder’s properties or assets, (iii) constitute a violation by such Stockholder of any law or regulation of any jurisdiction, (iv) render any state takeover statute or similar statute or regulation, applicable to the Merger or any other transaction involving Parent, or (v) if such Stockholder is not a natural person, contravene or conflict with such Stockholder’s certificate of incorporation, bylaws, trust agreement or other organizational documents, in each case, except for any conflict, breach, default or violation described above which would not adversely affect the ability of such Stockholder to perform its obligations hereunder or consummate the transactions contemplated hereby.

(f) No Litigation. There is no suit, claim, action, investigation or proceeding pending or, to the knowledge of such Stockholder, threatened against such Stockholder at law or in equity before or by any Governmental Entity that could reasonably be expected to impair the ability of such Stockholder to perform its obligations hereunder or consummate the transactions contemplated hereby.

(g) No Fees. No broker, investment banker, financial advisor or other person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of such Stockholder in his capacity as Stockholder.

The term (the “Term”) of this Agreement and the Proxies granted pursuant hereto, with respect to any Stockholder, shall commence on the date hereof and shall terminate upon the earliest of (i) the mutual agreement of Parent and such Stockholder, (ii) the Effective Time (as defined in the Merger Agreement) and (iii) the termination of the Merger Agreement in accordance with its terms; provided that (A) nothing herein shall relieve any party hereto from liability for any breach of this Agreement and (B) this Section 6, Section 7 and Section 8 shall survive any termination of this Agreement.

7. No Limitation. Notwithstanding anything to the contrary contained herein, Stockholder makes no agreement or understanding in this Agreement in Stockholder’s capacity as a director or officer of the Company or any of its Subsidiaries (if Stockholder holds such office), and nothing in this Agreement: (a) will limit or affect any actions or omissions taken by Stockholder in Stockholder’s capacity as such a director or officer, including in exercising rights under the Merger Agreement or with respect to any Acquisition Proposal, and no such actions or omissions shall be deemed a breach of this Agreement or (b) will be construed to prohibit, limit or restrict Stockholder from exercising Stockholder’s fiduciary duties as an officer or director to the Company or its stockholders.

8. Miscellaneous.

(a) Entire Agreement. This Agreement (together with Schedule I and Exhibit A) and the Proxies constitute the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof.

(b) Reasonable Efforts. Subject to the terms and conditions of this Agreement, each of the parties hereto agrees to use all reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws to consummate and make effective the transactions contemplated hereby. At the other party’s reasonable request and without further consideration, each party hereto shall execute and deliver such additional documents and take all such further lawful action as may be necessary or desirable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated hereby. Without limiting the foregoing, each Stockholder shall execute and deliver to Parent and any of its designees any additional proxies, including with respect to Additional Owned Shares, reasonably requested by Parent in furtherance of this Agreement.

(g) Severability. This Agreement shall be deemed severable; the invalidity, illegality or unenforceability of any term or provision of this Agreement shall not affect the validity, legality or enforceability of the balance of this Agreement or of any other term hereof, which shall remain in full force and effect. If any of the provisions hereof are determined to be invalid, illegal or unenforceable, 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.

(i) No Waiver. The failure of any party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with such party’s obligations hereunder, and any custom or practice of the parties at variance with the terms hereof, shall not constitute a waiver by such party of such party’s right to exercise any such or other right, power or remedy or to demand such compliance.

(j) No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Agreement.

(l) Submission to Jurisdiction. Each of the parties hereto irrevocably submits itself to the personal jurisdiction of any court of proper subject matter jurisdiction in the State of California, City of Los Angeles (and any appellate court therefrom) in the event any dispute arises out of this Agreement, the Merger Agreement or the Merger, and agrees that it will not bring any Action (as defined in the Merger Agreement) relating to this Agreement, the Merger Agreement or the Merger in any court other than such a court in the State of California, other than Actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court. Each of the parties hereto hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action related to or arising out of this Agreement, the Merger Agreement or the Merger, that (i) the Action in any such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Agreement or the subject matter hereof may not be enforced in or by such courts. Each party to this Agreement hereby irrevocably and unconditionally agrees that service of any process, summons, notice or document by U.S. registered mail, or otherwise in the manner provided for notices in Section 10(f) hereof, shall be effective service of process for any

such action, suit or proceeding brought against it in any such court. Each of the parties hereto agrees that a final judgment in any such action, suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

(m) Waiver of Jury Trial. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10(m).
