(d)           There is no suit, claim, action, proceeding, hearing, notice of violation, investigation, arbitration or demand letter pending or, to the knowledge of Stockholder, threatened against or affecting Stockholder that, individually or in the aggregate, could reasonably be expected to impair the ability of Stockholder to perform its obligations hereunder or consummate the transactions contemplated hereby.

(f)            Stockholder has received and reviewed a copy of the Merger Agreement.  Stockholder understands and acknowledges that (i) Parent and the Purchaser are entering into the Merger Agreement in reliance upon Stockholder’s execution, delivery and performance of this Agreement and (ii) the actual Offer Price may be less than the initial Offer Price in the event that the aggregate amount of the Company’s Expenses exceeds or is expected to exceed the Company Expense Cap as of the Expiration Date as set forth in Section 1.1(c) of the Merger Agreement.

SECTION 2.           Representations and Warranties of Parent and the Purchaser.  Each of Parent and the Purchaser hereby, jointly and severally, represents and warrants to Stockholder as follows:

(a)           Each of Parent and the Purchaser is a corporation duly organized, validly existing and in good standing under the laws of the state of Delaware, and each of Parent and the Purchaser has all necessary corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby.

(b)           This Agreement has been duly and validly authorized by all necessary corporate action, and no other corporate proceedings on the part of Parent or the Purchaser are necessary to authorize this Agreement or to consummate the transactions contemplated hereby.  This Agreement has been duly authorized and validly executed and delivered by Parent and the Purchaser, and assuming execution and delivery by Stockholder, constitutes a legal, valid and binding obligation of Parent and the Purchaser, enforceable against Parent and the Purchaser in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,

3

moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law).

(c)           The execution and delivery of this Agreement and the consummation by Parent and the Purchaser of the transactions contemplated hereby and the performance by Parent and the Purchaser of their respective obligations hereunder will not (i) conflict with or violate any provision of the certificate of incorporation or by-laws of Parent or the Purchaser, (ii) conflict with or violate, or require any consent, approval, or notice under, any Law applicable to Parent or the Purchaser or any of their respective properties or assets, or (iii) require any consent or approval under, violate, conflict with, result in any breach of or any loss of any benefit under, or constitute a default under, or result in termination or give to others any right of termination, amendment, acceleration or cancellation of any contract, trust, commitment, agreement, understanding, arrangement or restriction of any kind to which Parent or the Purchaser is a party or by which Parent or the Purchaser or their respective properties or assets are bound except with respect to clauses (ii) and (iii) for any conflict, breach, default or violation described which would not adversely affect in any material respect the ability of Parent or the Purchaser to perform its obligations hereunder or consummate the transactions contemplated hereby.

SECTION 3.           Tender of the Covered Shares.

(a)           Unless this Agreement shall have been terminated in accordance with its terms, Stockholder hereby agrees that he shall tender (and deliver any certificates evidencing or an appropriate affidavit of lost certificate with respect thereto to the extent such certificates have been lost, misplaced or destroyed) his Covered Shares, or cause his Covered Shares to be tendered, into the Offer promptly following, and in any event no later than the tenth (10th) Business Day following the commencement of the Offer, or if Stockholder has not received the Offer Documents by such time, within two (2) Business Days following r eceipt of such documents but in any event prior to the Expiration Date (the “Tender Date”), free and clear of all Encumbrances.  If Stockholder acquires Covered Shares after the date hereof, including upon the exercise of Company Options, unless this Agreement shall have been terminated in accordance with its terms, Stockholder shall tender or cause to be tendered such Covered Shares on or before the Tender Date, or, if later, on or before the second (2nd) Business Day after such acquisition but in any event prior to the Expiration Date, free and clear of all Encumbrances.  Unless this Agreement shall have been terminated in accordance with its terms, Stockholder will not withdraw his Covered Shares, or cause his Covered Shares to be withdrawn, from the Offer at any time.

(b)           If the Offer is terminated or withdrawn by the Purchaser, or the Merger Agreement is terminated prior to the purchase of Covered Shares in the Offer, Parent and the Purchaser shall promptly return, and shall cause any depository acting on behalf of Parent and the Purchaser to return, all Covered Shares tendered by Stockholder in the Offer to Stockholder.

10

all references in this Agreement to “Sections” and “Schedules” are intended to refer to Sections of this Agreement and Schedules to this Agreement.  Unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive.  The words “hereof,” “hereto,” “hereby,” “herein,” “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not any particular section in which such words appear.  The parties hereto have participated jointly in the negotiation and drafting of this Agreement.  No provision of this Agreement shall be interpreted for or against any party hereto because that party or its legal representatives drafted the provision.

(c)           Counterparts.  This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

(d)           Entire Agreement.  This Agreement (together with the Merger Agreement and any other documents and instruments referred to herein and therein) constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all other prior agreements, representations and understandings, both written and oral, among the parties or any of them with respect to the subject matter hereof and thereof.

(e)           Governing Law.  This Agreement, and all matters arising hereunder or in connection herewith, shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to Laws that may be applicable under conflicts of Laws principles (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

(f)            Consent to Jurisdiction.  Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery or, if such court shall not have jurisdiction, any federal court located in the State of Delaware or other Delaware state court, in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in such courts, (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in any such court, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any such court, and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.  Each of the parties hereto agrees that a final judgment in any such action 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.  Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 15(a). Nothing in this

11

Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(g)           WAIVER OF TRIAL BY JURY.  EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT 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 AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.  EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) 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, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIV ERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 15(g).

(h)           Assignment.  The Agreement shall not be assigned by any party by operation of Law or otherwise without the prior written consent of the other parties, provided that Parent and the Purchaser may assign any of their respective rights and obligations to any direct or indirect Subsidiary of Parent, but no such assignment shall relieve Parent or the Purchaser, as the case may be, of its obligations hereunder.

(i)            Parties in Interest.  This Agreement shall be binding upon and inure solely to the benefit of each party hereto and its successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(j)            Severability of Provisions.  If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by rule of 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 by this Agreement is not affected in any manner 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 the transactions are fulfilled to the extent possible.

(k)           Specific Performance.  The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.
