Terms not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement (as defined below). If the terms of this Agreement conflict in any way with the provisions of the Merger Agreement, then the provisions of the Merger Agreement shall control.

RECITALS

A. The execution and delivery of this Agreement by Stockholder is a material inducement to the willingness of Acquiror to enter into that certain Agreement and Plan of Merger, dated as of November 11, 2003 (the “Merger Agreement”), by and among Acquiror, Los Angeles Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of Acquiror (“Sub”) and the Company, pursuant to which Sub will merge with and into the Company (the “Merger”), and the Company will survive the Merger and become a wholly-owned subsidiary of Acquiror.

B. Stockholder understands and acknowledges that the Company and Acquiror are entitled to rely on (i) the truth and accuracy of Stockholder’s representations contained herein and (ii) Stockholder’s performance of the obligations set forth herein.

NOW, THEREFORE, in consideration of the premises and the covenants and agreements set forth in the Merger Agreement and in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Restrictions on Shares.

(a) Stockholder shall not, directly or indirectly, transfer (except as may be specifically required by court order or by operation of law), sell, exchange, pledge or otherwise dispose of or Encumber the Shares (as such term is defined in Section 4) or any New Shares (as such term is defined in Section 1(d) below), or to make any offer or agreement relating thereto, at any time prior to the Expiration Date; provided, however, that nothing contained herein will be deemed to restrict the ability of Stockholder to exercise, prior to the Expiration Date, any Company Options held by Stockholder. As used herein, the term “Expiration Date” shall mean the earlier of (i) the Effective Time and (ii) the termination of the Merger Agreement in accordance with its terms.

(b) Except pursuant to the terms of this Agreement, Stockholder shall not, directly or indirectly, grant any proxies or powers of attorney with respect to any of the Shares, deposit any of the Shares into a voting trust, or enter into a voting agreement with respect to any of the Shares.

(c) Stockholder shall not, directly or indirectly, take any action that would make any representation or warranty contained herein untrue or incorrect or have the effect of impairing the ability of Stockholder to perform its obligations under this Agreement or preventing or delaying the consummation of any of the transactions contemplated hereby.

(d) Any shares of Company Common Stock or other securities of the Company that Stockholder purchases or with respect to which Stockholder otherwise acquires beneficial ownership after

the date of this Agreement and prior to the Expiration Date, including pursuant to the exercise of options to purchase Shares (collectively, the “New Shares”) shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares.

2. Agreement to Vote Shares. Prior to the Expiration Date, at every meeting of the stockholders of the Company called with respect to any of the following, and at every adjournment thereof, and on every action or approval by written resolution or consent of the stockholders of the Company with respect to any of the following, Stockholder shall vote the Shares and any New Shares in favor of approval of the Merger, the Merger Agreement and the Certificate of Merger and any matter that could reasonably be expected to facilitate the Merger and against any Acquisition Proposal (as such term is defined in Section 5.3(a) of the Merger Agreement) and any other matter that might reasonably be expected to impede, delay or materially and adversely affect the Merger, any of the transactions contemplated by the Merger Agreement. No agreement to vote or provide a written consent is hereby made with respect to any matter not enumerated above.

3. Irrevocable Proxy. Concurrently with the execution and delivery of this Agreement, Stockholder shall deliver to Acquiror a duly executed proxy in the form attached hereto as Exhibit A (the “Proxy”), which proxy is coupled with an interest, and, until the Expiration Date, shall be irrevocable to the fullest extent permitted by law, with respect to each and every meeting of stockholders of the Company or action or approval by written resolution or consent of stockholders of the Company with respect to the matters contemplated by Section 2 covering the total number of Shares and New Shares in respect of which Stockholder is entitled to vote at any such meeting or in connection with any such written consent. No proxy is hereby given with respect to any matters other than those enumerated in Section 2. Upon the execution of this Agreement by Stockholder, (i) Stockholder hereby revokes any and all prior proxies (other than the Proxy) given by Stockholder with respect to the subject matter contemplated by Section 2 and (ii) Stockholder shall not grant any subsequent proxies with respect to such subject matter until after the Expiration Date.

4. Representations, Warranties and Covenants of Stockholder. Stockholder hereby represents, warrants and covenants to Acquiror as follows:

(a) Stockholder is the beneficial or record owner of, or exercises voting power over, that number of shares of Company Common Stock set forth on the signature page hereto (all such shares owned beneficially or of record by Stockholder, or over which Stockholder exercises voting power, on the date hereof, collectively, the “Shares”). The Shares constitute Stockholder’s entire interest in the outstanding shares of Company Common Stock. No person not a signatory to this Agreement has a beneficial interest in or a right to acquire or vote any of the Shares (other than, if Stockholder is a partnership, the rights and interest of persons and entities that own partnership interests in Stockholder under the partnership agreement governing Stockholder and applicable partnership law). The Shares are and will be at all times up until the Expiration Date free and clear of any security interests, liens, claims, pledges, options, rights of first refusal, agreements, limitations on Stockholder’s voting rights, charges and other encumbrances of any nature that would adversely affect the Merger or the exercise or fulfillment of the rights and obligations of the Company and the parties to this Agreement. Stockholder’s principal residence or place of business is set forth on the signature page hereto.

(b) Stockholder has all requisite power, capacity and authority to enter into this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by Stockholder and the consummation by Stockholder of the transactions contemplated hereby have been duly authorized by all necessary action, if any, on the part of Stockholder. This Agreement has been duly executed and delivered by Stockholder and, assuming the due authorization, execution and delivery of this Agreement by Acquiror, constitutes a valid and binding obligation of

Stockholder, enforceable against Stockholder in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally and to general principles of equity.

(c) The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not, conflict with, result in a breach or violation of or default (with or without notice or lapse of time or both) under, or require notice to or the consent of any person under, any agreement, law, rule, regulation, judgment, order or decree by which Stockholder is bound, except for such conflicts, breaches, violations or defaults that would not, individually or in the aggregate, prevent or delay consummation of the Merger and the transactions contemplated by the Merger Agreement and this Agreement or otherwise prevent or delay Stockholder from performing his, her or its obligations under this Agreement.

(d) Until the Expiration Date, Stockholder, in its capacity as a stockholder of the Company, shall not, and shall not authorize, encourage or permit any person or entity on Stockholder’s behalf to, directly or indirectly, take any action that would, or could reasonably be expected to result in the violation by the Company of Section 5.3 of the Merger Agreement. No action or failure to take action by Stockholder in Stockholder’s capacity as an officer or director of the Company shall be deemed to be an action taken by Stockholder in his or her capacity as a stockholder of the Company, and nothing herein will limit or affect, or give rise to any liability to Stockholder by virtue of, any actions taken by Stockholder solely in his or her capacity as an officer or director of the Company in exercising his or her rights or obligations under the Merger Agreement or applicable law.

5. Acknowledgement of Section 83(b) Filings. Except as otherwise disclosed to Acquiror in writing, Stockholder has filed on a timely basis with the appropriate Internal Revenue Service Center an election under Section 83(b) of the Code with respect to any restricted stock awards or other restricted property Stockholder has received from the Company and/or any of its affiliates so that Stockholder shall not recognize any taxable income under Section 83 of the Code solely as a result of such restricted stock or other restricted property becoming vested or transferable.

6. Consent and Waiver; Termination of Existing Agreements. Stockholder hereby gives any consents or waivers that are reasonably required for the consummation of the Merger under the terms of any agreement or instrument to which Stockholder is a party or subject or in respect of any rights Stockholder may have in connection with the Merger or the other transactions provided for in the Merger Agreement (whether such rights exist under the certificate of incorporation or bylaws of the Company, any Contract to which the Company is a party or by which it is, or any of its assets are, bound under statutory or common law or otherwise) other than waivers of any rights expressly provided for in the Merger Agreement or this Agreement. Without limiting the generality or effect of the foregoing, Stockholder hereby waives any and all rights to contest or object to the execution and delivery of the Merger Agreement and the consummation of the Merger and the other transactions provided for in the Merger Agreement, or to seek damages or other legal or equitable relief in connection therewith. From and after the Effective Time, Stockholder’s right to receive cash on the terms and subject to the conditions set forth in the Merger Agreement shall constitute Stockholder’s sole and exclusive right against the Company and/or Acquiror in respect of Stockholder’s ownership of the Shares or status as a stockholder of the Company or any agreement or instrument with the Company pertaining to the Shares or Stockholder’s status as a stockholder of the Company.

7. Confidentiality. Stockholder shall hold any information regarding this Agreement and the Merger in strict confidence and shall not divulge any such information to any third person until the Acquiror has publicly disclosed the Merger. Neither the Stockholder, nor any of its affiliates shall issue or cause the publication of any press release or other public announcement with respect to this Agreement,

the Merger, the Merger Agreement or the other transactions contemplated thereby without the prior written consent of the Acquiror, except as may be required by law or by any listing agreement with, or the policies of, the Nasdaq Stock Market or an applicable national securities exchange in which circumstance such announcing party shall make reasonable efforts to consult with the Acquiror to the extent practicable.

8. Appraisal Rights. Stockholder agrees not to exercise any rights of appraisal or any dissenters’ rights that Stockholder may have (whether under applicable law or otherwise) or could potentially have or acquire in connection with the Merger.

9. Miscellaneous.

(a) Notices. All notices and other communications hereunder shall be in writing and shall be deemed given on (i) the date of delivery, if delivered personally or by commercial delivery service, or (ii) on the date of confirmation of receipt (or the next Business Day, if the date of confirmation of receipt is not a Business Day), if sent via facsimile (with confirmation of receipt), to the parties hereto at the following address (or at such other address for a party as shall be specified by like notice):

(b) Interpretation. When a reference is made in this Agreement to Sections or Exhibits, such reference shall be to a Section of or an Exhibit to this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. The words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.” The phrases “the date of this Agreement”, “the date hereof”, and terms of similar import, unless the context otherwise requires, shall be deemed to refer to the date first above written.

(c) Specific Performance; Injunctive Relief. The parties hereto acknowledge that Acquiror will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth herein or in the Proxy. Therefore, it is agreed that, in addition to any other remedies that may be available to Acquiror upon any such violation of this

Agreement or the Proxy, Acquiror shall have the right to enforce such covenants and agreements and the Proxy by specific performance, injunctive relief or by any other means available to Acquiror at law or in equity and Stockholder hereby waives any and all defenses which could exist in its favor in connection with such enforcement and waives any requirement for the security or posting of any bond in connection with such enforcement.

(d) Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same instrument and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties hereto; it being understood that all parties need not sign the same counterpart.

(e) Entire Agreement; Nonassignability; Parties in Interest. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto (including, without limitation, the Proxy) (i) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and (ii) are not intended to confer, and shall not be construed as conferring, upon any person other than the parties hereto any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests, or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by Stockholder without the prior written consent of Acquiror, and any such assignment or delegation that is not consented to shall be null and void. This Agreement, together with any rights, interests or obligations of Acquiror hereunder, may be assigned or delegated in whole or in part by Acquiror to any affiliate of Acquiror without the consent of or any action by Stockholder upon notice by Acquiror to Stockholder as herein provided. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns (including, without limitation, any person to whom any Shares are sold, transferred or assigned).

(f) Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to use their commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(g) Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy shall not preclude the exercise of any other remedy.

(h) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of California without reference to such state’s principles of conflicts of law. Each of the parties hereto irrevocably consents to the exclusive jurisdiction of any court located within the State of California, in connection with any matter based upon or arising out of this Agreement or the matters contemplated herein, agrees that process may be served upon them in any manner authorized by the laws of the State of California for such persons and waives and covenants not to assert or plead any objection which they might otherwise have to such jurisdiction and such process.

(i) Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the

application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document shall be construed against the party drafting such agreement or document.

(j) Additional Documents, Etc. Stockholder shall execute and deliver any additional documents necessary or desirable, in the reasonable opinion of Acquiror, to carry out the purpose and intent of this Agreement. Without limiting the generality or effect of the foregoing or any other obligation of Stockholder hereunder, Stockholder hereby authorizes Acquiror to deliver a copy of this Agreement to the Company and hereby agrees that each of the Company and Acquiror may rely upon such delivery as conclusively evidencing the consents, waivers and terminations of Stockholder referred to in Section 6, in each case for purposes of all agreements and instruments to which such elections, consents, waivers and/or terminations are applicable or relevant.

(k) Termination. This Agreement shall terminate and shall have not further force or effect as of the Expiration Date, provided, that no such termination shall relieve any party from liability for any breach of this Agreement prior to such termination.

(l) Legal Counsel. Stockholder acknowledges that counsel to the Company has represented the Company in connection with the Merger Agreement and the transactions contemplated thereby, and further acknowledges and agrees as follows: (i) counsel to the Company is not representing the interests of Stockholder, and Stockholder is not relying on counsel to the Company in determining whether to enter into this Agreement; and (ii) Stockholder has been advised to seek independent counsel, to the extent Stockholder deems it appropriate, to protect Stockholder’s interests in connection herewith and therewith.
