(b) Restricted Merger Cash.

(i) If any shares of Company Common Stock outstanding immediately prior to the Effective Time are Restricted, then the Merger Cash paid upon conversion of such Restricted shares of Company Common Stock will also be Restricted and subject to the same right of repurchase, risk of forfeiture or risk of divestment in favor of Parent as previously existed in favor of the Company; provided, however, that Parent shall exercise its right of repurchase with respect to the Restricted Merger Cash payable upon conversion of each Restricted share of Company Common Stock converted in the Merger by paying an amount of cash, without interest, equal to the repurchase price that was applicable to such Restricted share of Company Common Stock immediately prior to the Effective Time. Merger Cash that is Restricted shall be held by Parent until it is no longer Restricted and thereafter, subject to Section 1.7(c), shall be promptly paid by Parent to the applicable former Company Stockholder.

(ii) The Company shall take all action that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any right of repurchase or other right set forth in any Stock Restriction Agreement.

(c) Escrow. Of the Merger Cash payable pursuant to Section 1.7(a) in respect of each share of Company Capital Stock issued and outstanding immediately prior to the Effective Time, a portion thereof equal to the Escrow Percentage will, without any act of any Company Stockholder, be deposited with the Escrow Agent, such deposit to constitute an Escrow Fund (as defined in Section 7.2) to be governed by the terms of Section 7.2 (such Merger Cash deposited in the Escrow Fund, the “Escrow Cash”). Set forth opposite each Company Stockholder’s name on Exhibit C is a preliminary schedule showing the Escrow Cash to be contributed on behalf of each such Company Stockholder, subject to adjustment for occurrences between the date of this Agreement and the Closing Date that affect the allocation of Merger Cash. With respect to each Company Stockholder who will receive Merger Cash pursuant to Section 1.7(a) that is Restricted, (i) the contributions on behalf of such Company Stockholder to the Escrow Cash shall be comprised of Merger Cash that is Restricted and Merger Cash that is Unrestricted in the same proportion that the total amount of Merger Cash such Company Stockholder is entitled to receive is comprised of Merger Cash that is Restricted and Merger Cash that is Unrestricted and (ii) the Restricted Merger Cash contributed on behalf of such Company Stockholder included in the Escrow Cash shall be allocated among the amounts of Restricted Merger Cash that Vest at different times in the same proportions as the total amount of such Company Stockholder’s Restricted Merger Cash that Vests at each such time. Any fraction of a cent of Merger Cash that would otherwise result from the payment of Merger Cash to be deposited into Escrow Fund pursuant to this Section 1.7(c) by virtue of ownership of outstanding shares of Company Capital Stock shall be rounded up to the nearest whole

-12-

cent, and any fraction of a cent that would otherwise result from the payment of the remaining Merger Cash which each such Company Stockholder would otherwise be entitled to receive under Section 1.7(a) by virtue of ownership of outstanding shares of Company Capital Stock shall be rounded down to the nearest whole cent. As soon as practicable after the Effective Time, and subject to and in accordance with the provisions of Section 7.2, Parent shall cause to be distributed to the Escrow Agent a wire transfer in the aggregate amount of Merger Cash included in the Escrow Cash. The Escrow Cash deposited in the Escrow Fund shall be available to compensate Parent as provided in Article VII. Any income, gains, losses and expenses of the Escrow Fund shall be reported by the parties for all income tax purposes in a manner consistent with Proposed Treasury Regulation Section 1.468B-8.

At the Effective Time, each outstanding Lower-Priced Company Stock Option shall be substituted with an option granted by Parent pursuant to the 2003 Merger and Employment Inducement Stock Option Plan of Parent, and all outstanding Company Warrants shall be assumed by Parent in accordance with Section 5.1. At the Effective Time all Company Stock Options that are not Lower-Priced Company Stock Options will not be substituted with Parent stock options or assumed.

(f) Capital Stock of Merger Sub. Each share of common stock, $0.001 par value per share, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, $0.001 par value per share, of the Surviving Corporation. Each certificate evidencing ownership of shares of Merger Sub Common Stock shall evidence ownership of such shares of capital stock of the Surviving Corporation.

1.8 Dissenting Shares.

(a) Notwithstanding any other provision of this Agreement to the contrary, shares of Company Capital Stock that have not been voted in favor of adoption of this Agreement and with respect to which a demand for payment and appraisal have been properly made in accordance with Section 262 of Delaware Law or Chapter 13 of California Law (“Dissenting Shares”), will not be converted into the right to receive the Merger Cash otherwise payable with respect to such shares of Company Capital Stock after the Effective Time but will be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to Delaware Law or California Law, as applicable.

(b) If a holder of Dissenting Shares (a “Dissenting Stockholder”) withdraws such holder’s demand for such payment and appraisal or becomes ineligible for such payment and appraisal then, as of the Effective Time or the occurrence of such event of withdrawal or ineligibility,

-13-

whichever last occurs, such holder’s Dissenting Shares will cease to be Dissenting Shares and will be converted into the right to receive, and will be exchangeable for, the Merger Cash into which such Dissenting Shares would have been converted pursuant to Section 1.7(a), subject to the escrow provisions described in Section 1.7(c) and Article VII of this Agreement.

(c) The Company will give Parent prompt notice of any written demand received by the Company from a holder of Dissenting Shares for appraisal of shares of Company Capital Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demand. The Company agrees that, except with the prior written consent of Parent, or as required under Delaware Law or California Law, as applicable, it will not voluntarily make any payment with respect to, or settle or offer or agree to settle, any such demand for appraisal. Each Dissenting Stockholder who, pursuant to Section 262 of Delaware Law or Chapter 13 of California Law, as applicable, becomes entitled to payment of the value of the Dissenting Shares will receive payment therefor (but only after the value therefor has been agreed upon or finally determined pursuant to such provisions).

(d) The aggregate amount required by a court of law (and not through any voluntary settlement or agreement by Parent) to be paid by Parent or the Surviving Corporation to any Dissenting Stockholders for Dissenting Shares pursuant to Section 262 of Delaware Law or Chapter 13 of California Law, as applicable, in excess of the aggregate value such Dissenting Stockholders would have received in the Merger for such Dissenting Shares shall constitute “Excess Appraisal Payments.” Each of Parent and the Company agree that the amount of the Excess Appraisal Payments and all reasonable costs, fees and expenses (including attorneys fees and expenses) associated with the adjudication thereof shall constitute Losses and, without regard for the limitations set forth in Section 7.2(i), Parent shall be entitled to recover such amount from the Escrow Fund.

1.9 Surrender of Certificates.

(a) Payment Agent. Parent shall select a bank or trust company reasonably acceptable to the Company to act as the payment agent (the “Payment Agent”) in the Merger.

(b) Parent to Provide Merger Cash. At the Closing, Parent shall make available to the Payment Agent for payment in accordance with this Article I, the Merger Cash payable pursuant to Section 1.7 (subject to the escrow provisions of Section 1.7(c)) upon conversion of outstanding shares of Company Capital Stock.

(c) Exchange Procedures. At the Closing, Parent shall cause the Payment Agent to deliver to each holder of record (as of the Effective Time) of a Certificate or Certificates: (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Payment Agent and shall contain such other customary provisions as Parent may reasonably specify); and (ii) instructions for use in effecting the surrender of the Certificates in exchange for Merger Cash. Upon surrender of Certificates for cancellation to the Payment Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed, validly executed and properly delivered in accordance with the instructions thereto, the holders of such

-14-

Certificates shall be entitled to receive in exchange therefor (subject in each case to the escrow provisions of Section 1.7(c)) the Merger Cash into which their shares of Company Capital Stock were converted at the Effective Time, and the Certificates so surrendered shall forthwith be canceled or terminated, as applicable. Until so surrendered, outstanding Certificates will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the ownership of the Merger Cash into which such shares of Company Capital Stock shall have been so converted.

(d) No Interest With Respect to Unexchanged Shares. No interest shall accrue on the Merger Cash payable with respect to any unsurrendered Certificates. Following surrender of any such Certificates, the Payment Agent shall deliver to the record holders thereof, in exchange therefor, without interest, the Merger Cash payable pursuant to Sections 1.7(a) or 5.1(b), as applicable.

(e) Transfers of Ownership. If Merger Cash is to be paid to a Person, other than the Person in whose name the Certificates surrendered in exchange therefor are registered, it will be a condition of the issuance and payment thereof that the Certificates so surrendered will be properly endorsed and otherwise in proper form for transfer and that the Persons requesting such exchange will have paid to Parent or any agent designated by it any transfer or other Taxes required by reason of payment of Merger Cash to any Person other than that of the registered holder of the Certificates surrendered, or established to the satisfaction of Parent or any agent designated by it that such Tax has been paid or is not payable.

(f) Required Withholding. Each of the Payment Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement and the transactions contemplated hereby to any holder or former holder of Company Capital Stock or any Person to whom Merger Cash shall be paid or payable such amounts as may be required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

(g) No Liability. Notwithstanding anything to the contrary in this Section 1.9, neither the Payment Agent, the Surviving Corporation nor any Party hereto shall be liable to a holder of Merger Cash or shares of Company Capital Stock for any amount properly paid to a public official or Government Body pursuant to any applicable abandoned property, escheat or similar law.

1.10 No Further Ownership Rights in Company Capital Stock. All Merger Cash paid in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

1.11 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or

-15-

destroyed, the Payment Agent shall pay in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Cash into which the shares of Company Capital Stock represented by such Certificates were converted pursuant to Section 1.7; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Cash require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

1.12 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Company and Merger Sub, the officers and directors of the Surviving Corporation will take all such lawful and necessary action.

1.13 Tax Matters. The Parties acknowledge and agree that the Merger will be a taxable transaction, and agree to report the Merger as a taxable transaction for all tax purposes.

Parent and Merger Sub represent and warrant to the Company as follows:

3.1 Organization, Standing and Power. Each of Parent and Merger Sub is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has the requisite corporate power and authority to own, lease and operate its assets and properties and to carry on its business as it is now being conducted, except where the failure to do so would not, individually or in the aggregate, have a Material Adverse Effect on Parent or Merger Sub. Parent is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its activities makes such qualification or licensing necessary, except for such failures to be so duly qualified or licensed and in good standing that would not, either individually or in the aggregate, have a Material Adverse Effect on Parent.

3.2 Authority. Each of Parent and Merger Sub has the requisite corporate power and authority to enter into this Agreement and the Ancillary Agreements to which it is a party, and to consummate the transactions contemplated hereby and thereby. The execution and delivery by each of Parent and Merger Sub of this Agreement and the Ancillary Agreements to which it is a party, and the consummation by each of Parent and Merger Sub of the transactions contemplated hereby and thereby, have been duly authorized by all necessary corporate action on the part of each of Parent and

-45-

Merger Sub, subject to the filing of the Certificate of Merger with the Secretary of State of the State of Delaware. This Agreement and the Ancillary Agreements to which it is a party and that have been executed and delivered contemporaneously with this Agreement, have been duly executed and delivered by each of Parent and Merger Sub. Assuming the due authorization, execution and delivery by the other Parties hereto and thereto and the validity and binding effect hereof and thereof on the other Parties hereto and thereto, this Agreement and the Ancillary Agreements to which it is a party constitute valid and binding obligations of each of Parent and Merger Sub enforceable against it in accordance with their respective terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by the effect of general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

3.3 No Violation; Consents and Approvals.

(a) The execution and delivery by Parent and Merger Sub of this Agreement and the Ancillary Agreements to which they are parties and the performance by Parent and Merger Sub of their respective obligations pursuant hereto and thereto will not (with or without notice or lapse of time, or both) conflict with or result in any violation of any provision of (i) the Organizational Documents of Parent or Merger Sub, or (ii) any Legal Requirement applicable to Parent or Merger Sub or any of their respective properties or assets other than compliance with the requirements set forth in Section 3.3(b) below, (iii) any Contract applicable to Parent or any of its properties or assets, or (iv) any judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Parent or any of its properties or assets, other than in the case of clauses (i), (ii), (iii) and (iv) any such violation, default, right of termination, cancellation or acceleration or Lien that individually or in the aggregate would not impair in any material respect the ability of Parent to perform its obligations under this Agreement, or prevent or materially delay the consummation of any of the transactions contemplated by this Agreement.

(b) No filing or registration with, or authorization, consent or approval of, any Governmental Body is required by or with respect to Parent or Merger Sub in connection with the execution and delivery by each of Parent or Merger Sub of this Agreement or the Ancillary Agreements to which it is a party or is necessary for the consummation by each of Parent or Merger Sub of the Merger and the other transactions contemplated by this Agreement or the Ancillary Agreements to which it is a party, except for (i) the filing of the Certificate of Merger with the Secretary of State of the State of Delaware (ii) applicable requirements, if any, of U.S. federal securities laws, Blue Sky Laws and the Nasdaq Stock Market, (iii) such filings, authorizations, orders or approvals as may be required under the HSR Act, if any, (iv) applicable requirements, if any, under foreign laws and (v) such other consents, orders, authorizations, registrations, declarations and filings the failure of which to be obtained or made would not, individually or in the aggregate, have a Material Adverse Effect on Parent, materially impair the ability of Parent or Merger Sub to perform its obligations hereunder or under the Ancillary Agreements, or prevent the consummation of any of the transactions contemplated hereby or thereby.

3.4 SEC Documents and Other Reports. Parent has filed all documents required to be filed by it with the SEC since December 27, 2002 (the “Parent SEC Documents”). As of their respective filing dates, the Parent SEC Documents complied in all material respects with the requirements of

-46-

the Securities Act or the Exchange Act, as the case may be and, at the respective times they were filed, none of the Parent SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except to the extent corrected in a subsequently filed Parent SEC Document prior to the date hereof. The consolidated financial statements (including, in each case, any notes thereto) of Parent included in the Parent SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, were prepared in accordance with GAAP (except, in the case of the unaudited statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis during the periods involved (except as may be indicated therein or in the notes thereto) and fairly presented in all material respects the consolidated financial position of Parent and its consolidated subsidiaries as at the respective dates thereof and the consolidated results of their operations and their consolidated cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments and to any other adjustments described therein).

3.5 Actions and Proceedings. As of the date of this Agreement, there are no actions, suits, labor disputes or other litigation, legal or administrative proceedings or governmental investigations pending or, to the Knowledge of Parent, threatened against Parent or any of its properties, assets or business relating to the transactions contemplated by this Agreement and the Ancillary Agreements.

3.6 Information Statement. None of the information supplied or to be supplied by Parent for inclusion in the Information Statement shall, on the date it is first mailed to the Company Stockholders, at the time of the Stockholder Meeting or at the Effective Time, contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary in order to make the statement therein, in light of circumstances under which they are made, not misleading, or omit to state any material fact necessary to correct any statement in any earlier communication with respect to the solicitation of proxies for the Stockholder Meeting which has become misleading.

Subject to Section 4.3, during the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement pursuant to its terms or the Effective Time, the Company will not, and will not permit any Acquired Company to, without the prior consent of Parent, take any affirmative action, or fail to take any reasonable action within its control, as a result of which any of the changes or events listed in Section 2.7 is likely to occur.

In addition, except as permitted by the terms of this Agreement or as specifically set forth in Section 4.1 of the Company Letter or Section 4.3, without the prior written consent of Parent, during the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement pursuant to its terms or the Effective Time, the Company shall not, nor shall the Company permit any Acquired Company to, do any of the following:

(c) Commence or settle any lawsuit, or settle any threat of any lawsuit or proceeding or other investigation against it, other than (i) for the routine collection of bills, (ii) in such cases where it, in good faith, determines that failure to commence suit would result in the material

-48-

impairment of a valuable aspect of its business, provided that it consults with Parent prior to the filing of such a suit, or (iii) to enforce its rights hereunder or under any Ancillary Agreements related hereto;

(d) Take, or agree in writing or otherwise to take, any of the foregoing actions or any other action that would or could reasonably be expected to prevent the Acquired Companies from performing or cause the Acquired Companies not to perform its covenants hereunder or cause or result in any of its representations or warranties contained herein to be untrue or incorrect.

Without limiting the foregoing, it is understood that any violation of the restrictions set forth above by any Acquired Company or any officer, director, agent, representative or affiliate thereof shall be deemed to be a breach of this Agreement by the Company.

The representations and warranties of the Company contained in this Agreement, or in any certificate, schedule or other instrument delivered pursuant to this Agreement, shall terminate at 11:59 p.m. California time on the eighteen (18) month anniversary of the Closing Date (the “Escrow Termination Time”). The representations and warranties of Parent and Merger Sub contained in this Agreement, or in any certificate, schedule or other instrument delivered by Parent or Merger Sub pursuant to this Agreement, shall terminate at the effective Time.

7.2 Escrow Arrangements.

(a) Escrow Fund. The Escrow Fund shall be available to compensate Parent and its officers, directors, employees, agents, representatives, stockholders, controlling Persons and affiliates, including the Company after the Effective Time (the “Covered Parties”), or any of them, for any losses, liabilities, damages, deficiencies, costs and expenses, including reasonable attorneys’ fees and expenses of investigation and defense relating to such loss, liability, damage, deficiency,

-60-

cost or expense (hereinafter individually a “Loss” and collectively “Losses”) incurred or suffered by the Covered Parties, or any of them, directly or indirectly, including as a result of claims by third parties, as a result of (i) any breach or inaccuracy of a representation, warranty, covenant or agreement of the Company contained in this Agreement (or in any certificate, schedule or other instrument delivered by the Company pursuant to this Agreement), (ii) any failure by the Company to perform or comply with any covenant required to be performed by it prior to the Effective Time and contained in this Agreement or any Company Ancillary Agreement to which it is a party, (iii) the incurrence by the Company of third party transaction expenses in connection with this Agreement and the Merger, in excess of $8,825,000 (“Excess Transaction Expenses”), (iv) any Excess Appraisal Payments and (v) any of the matters set forth in Sections 7.2(a)-1 and 7.2(a)-2 of the Company Letter (hereinafter individually a “Covered Event” and collectively, the “Covered Events”). Except for claims for equitable relief and claims with respect to fraud solely against the person or persons committing or alleged to have committed such fraud, recovery pursuant to this Section 7.2(a) shall be the sole and exclusive remedy of Parent and Merger Sub for any Covered Event if the Merger contemplated hereby is consummated. If the Merger contemplated hereby is not consummated, nothing in this Agreement shall limit the liability of the Company with respect to the representations, warranties or covenants of the Company contained herein, and nothing in this Agreement shall limit the liability of Parent with respect to the representations, warranties or covenants of Parent contained herein.

(b) Deposit of Escrow Fund. Promptly after the Closing, the Escrow Cash, without any act of the Escrow Contributors, will be deposited with LaSalle Bank National Association, as escrow agent hereunder, or another institution acceptable to Parent and the Stockholder Representative (the “Escrow Agent”), such deposit of the Escrow Cash to constitute an escrow fund (the “Escrow Fund”) to be governed by the terms set forth herein. The Escrow Agent shall have no duty to confirm or verify the accuracy or correctness of the amount of any Escrow Cash deposited with it hereunder.

(i) Subject to the other provisions of this Section 7.2 the Escrow Fund shall be in existence immediately following the Effective Time and shall terminate at the Escrow Termination Time (the “Escrow Period”).

At the Escrow Termination Time, the Escrow Fund shall terminate with respect to any amounts of Escrow Cash remaining in the Escrow Fund at that time; provided, however, that the Escrow Period and the Escrow Fund shall not terminate with respect to any amount which, in the good faith judgment of Parent, subject to the good faith objection of the Stockholder Representative, is necessary to satisfy any then pending and unsatisfied claims specified in any Officer’s Certificate (as defined below) delivered to the Escrow Agent prior to the fifth (5^th) Business Day following the Escrow Termination Time with respect to pending and unsatisfied claims existing prior to such time. Promptly after all such claims have been resolved, the Escrow Agent shall deliver to the Escrow Contributors subject to the provisions of Section 7.2(c)(iii) below, the remaining portion of Escrow Cash, without interest, in the Escrow Fund, if any, not required to satisfy such claims (the “Remaining Portion”).

-61-

(ii) If Escrow Cash that is Restricted is released upon termination of the Escrow Period pursuant this Section 7.2(c)(ii), such Escrow Cash shall be released to Parent to be held by Parent pursuant to the terms of the Stock Restriction Agreement governing such Escrow Cash.

(iii) Within twenty (20) Business Days following the Escrow Termination Time, Parent will notify the Stockholder Representative and the Escrow Agent in writing of the portion of the Escrow Fund that may be distributed pursuant to this Section 7.2(c) (an “Escrow Distribution Notice”), and the allocation of such distribution. The Stockholder Representative shall have ten (10) Business Days following receipt of such notice from Parent during which to object to the contents thereof by sending written notice of such objection to Parent and to the Escrow Agent. If the Escrow Agent does not timely receive any such written objection from the Stockholder Representative, the Escrow Agent shall distribute Escrow Cash from the Escrow Fund in accordance with the Escrow Distribution Notice and will incur no liability, and shall be fully protected, in relying on such Escrow Distribution Notice and shall have no obligation to take any action until it has received such notice.

(d) Protection of Escrow Fund.

(i) The Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period, and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof.

(ii) At the direction in writing of Parent, the Escrow Cash will be invested in money market funds or government securities. In the absence of written instructions from Parent, the Escrow Agent shall invest as soon as reasonably practicable all balances for which it has not received specific written investment direction, including income earned, in the Federated Treasury Obligations Fund. All income earned on the Escrow Cash shall be part of the Escrow Fund, other than distributions to Parent pursuant to Section 1.7(c) hereof.

(e) Claims for Losses.

(i) Upon receipt by the Escrow Agent at any time on or before the fifth (5^th) Business Day following the Escrow Termination Time of an Officer’s Certificate (as defined below), subject to the last sentence of this Section 7.2(e) and the provisions of Section 7.2(f), the Escrow Agent shall deliver to Parent out of the Escrow Fund, as promptly as practicable, such amount of Escrow Cash as are set forth in the Officer’s Certificate. For purposes hereof, “Officer’s Certificate” means a certificate signed by any officer of Parent and delivered to the Escrow Agent, and such certificate shall (A) state that the Covered Party claiming compensation has paid or incurred or reasonably anticipates that it will have to pay or incur Losses; (B) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid or incurred, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant to which such item is related, and (C) the amount of Escrow Cash to be delivered to Parent in compensation for such Losses. Notwithstanding the foregoing, in no event shall any amounts be paid to any Covered Party out of the Escrow Fund with respect to any Loss that has not yet been paid or incurred, even if Parent has submitted an Officer’s

-62-

Certificate indicating that it reasonably anticipates paying or incurring such Loss, it being understood that any such amounts claimed on such Officer’s Certificate shall be held in the Escrow Fund pending final resolution of the claim notwithstanding the passing of the Escrow Termination Time.

(ii) Deliveries of Escrow Cash pursuant to Section 7.2(e)(i) above shall be made pro rata from the Escrow Fund contributions made by each Escrow Contributor based on the original contributions of Escrow Cash of each Escrow Contributor to the Escrow Fund.

(iii) With respect to any Escrow Contributor that contributed Escrow Cash that is Restricted, the delivery of Escrow Cash out of the Escrow Fund shall be allocated between Restricted and Unrestricted Escrow Cash in the same proportions as such Escrow Contributor’s entire contribution to the Escrow Fund is then allocated between Restricted and Unrestricted Escrow Cash. With respect to the Escrow Cash that is Restricted, the delivery out of the Escrow Fund shall be allocated among the different portions that Vest at different times in the same proportion as such Escrow Contributor’s entire contribution of Escrow Cash to the Escrow Fund is then allocated among such different portions that Vest at different times.

(iv) Notwithstanding the foregoing, the Escrow Agent’s sole duty with respect to the delivery of the Escrow Cash hereunder is to deliver the Escrow Cash to Parent or the Stockholder Representative, as the case may be, in accordance with the written instructions provided for in this Section 7.2, and the Escrow Agent has no duty to monitor or enforce compliance with this section, including determining whether or not the Escrow Cash to be released is Restricted.

(f) Objection to Claims; Resolution of Conflicts. At the time of delivery of any Officer’s Certificate to the Escrow Agent, Parent shall deliver a duplicate copy of such certificate to the Stockholder Representative, and for a period of ten (10) Business Days after such delivery, the Escrow Agent shall make no delivery to Parent of any portion of the Escrow Cash pursuant to Section 7.2(e) with respect to such Officer’s Certificate unless and until the Escrow Agent shall have received written authorization from the Stockholder Representative to make such delivery. After the expiration of such ten (10) Business Day period, the Escrow Agent shall make delivery of the Escrow Cash from the Escrow Fund in accordance with Section 7.2(e); provided, however, that no such payment or delivery may be made until resolution of any objection to the delivery of any Escrow Cash made pursuant to this Section 7.2(f) if the Stockholder Representative shall, in a written statement, make a good faith objection to the claim made in the Officer’s Certificate, and such written objection shall have been delivered to the Escrow Agent prior to the expiration of such ten (10) Business Day period. If the Escrow Agent does not timely receive any such written objection from the Stockholder Representative, the Escrow Agent shall distribute Escrow Cash from the Escrow Fund in accordance with the Officer’s Certificate and will incur no liability, and shall be fully protected, in relying on such Officer’s Certificate. Such failure by the Stockholder Representative to so object shall be an irrevocable acknowledgment by the Stockholder Representative that the Covered Party claiming a Loss or Losses is entitled to the full amount of the claim for Losses set forth in such Officer’s Certificate. If the Stockholder Representative has delivered such a written objection, the Stockholder Representative and Parent shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholder Representative and Parent should so agree, a memorandum setting forth such agreement shall be prepared and signed by the Stockholder Representative and the Covered Parties and

-63-

furnished to the Escrow Agent. Such memorandum shall state the amount of Escrow Cash to be released from the Escrow Fund in connection with such Losses. The Escrow Agent shall be entitled to rely on any such memorandum and distribute the Escrow Cash from the Escrow Fund in accordance with the terms thereof.

(g) Third Party Claims. In the event Parent becomes aware of a third-party claim which Parent reasonably believes may result in a demand for recovery of Losses, Parent shall notify the Stockholder Representative of such claim, and the Stockholder Representative shall be entitled on behalf of the Escrow Contributors, at its expense, to participate in, but not to determine or conduct, the defense of such claim. Parent shall have the right in its sole discretion to conduct the defense of and settle any such claim; provided, however, that (i) Parent shall first consult with the Stockholder Representative regarding such settlement, (ii) Parent shall not, without the prior written consent of the Stockholder Representative, settle any demand for appraisal of or dissenters rights with respect to Company Capital Stock for an amount that exceeds the amount of Merger Consideration payable pursuant to Section 1.7 to the Company Stockholder making such demand and (iii) except with the consent of the Stockholder Representative, no settlement of any such claim with third-party claimants shall be determinative of whether Parent or any other party is entitled to compensation pursuant to this Article VII or the amount of such compensation, if any. In the event that the Stockholder Representative has consented to any such settlement, the Escrow Contributors shall have no power or authority to object under any provision of this Article VII to the amount of any claim by Parent with respect to such settlement.

(h) Limitations on Claims from Escrow Fund. The Covered Parties shall not be entitled to recovery of Losses under this Section 7.2 unless and until the Covered Parties have paid or incurred Losses in excess of $500,000 in the aggregate (the “Basket Amount”), in which case the Covered Parties shall be entitled to recover all Losses so identified including the Basket Amount; provided however, that claims for recovery of Losses in respect of any breach of the representations and warranties set forth in Section 2.10, Excess Transaction Expenses, Excess Appraisal Payments and any of the matters set forth in Section 7.2(a)-1 of the Company Letter shall not be subject to the Basket Amount limitation, and such claims shall not count toward satisfaction of the Basket Amount for purposes of other claims for recovery of Losses.

(i) Escrow Agent’s Duties.

(i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth in Section 1.7(c) hereof and this Section 7.2, and as set forth in any additional written escrow instructions which the Escrow Agent may receive after the date of this Agreement which are signed by an officer of Parent and the Stockholder Representative (and which are acceptable to the Escrow Agent), and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties.

(ii) The Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the Parties hereto or by any other person, excepting only orders or process of courts of law, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case the Escrow Agent obeys or complies with any such order,

-64-

judgment or decree of any court, the Escrow Agent shall be fully protected and shall not be liable to any of the Parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the Parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

(iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent.

(v) In performing any duties under this Agreement, the Escrow Agent shall not be liable to any person or entity for damages, losses, liabilities, penalties, claims, settlements, judgments, costs or expenses, except for gross negligence or willful misconduct on the part of the Escrow Agent (each as may be finally determined by a court of competent jurisdiction). The Escrow Agent shall not incur any liability for any action taken, suffered or omitted in reliance upon any instrument, including any written statement of affidavit provided for in this Agreement that the Escrow Agent shall reasonably believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with legal counsel (whether such counsel shall be regularly retained or specifically employed) in connection with performing the Escrow Agent’s duties under this Agreement and shall be fully protected and shall incur no liability with respect to any action taken, suffered, or omitted to be taken by it in accordance with the advice of counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any Party to this Agreement.

(vi) If any controversy arises between the Parties to this Agreement, or with any other Party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and the Escrow Cash and may wait for settlement of any such controversy by final appropriate legal proceedings or other means as, in the Escrow Agent’s discretion, may be required, despite what may be set forth elsewhere in this Agreement. In such event, the Escrow Agent will not be liable for damages. Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and the Escrow Cash held in escrow, except all costs, expenses, charges and reasonable attorney fees incurred by the Escrow Agent due to the interpleader action, which the Parties jointly and severally agree to pay. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liability imposed by the terms of this Agreement.

(vii) The Parties (other than the Escrow Agent) and their respective successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, penalties, claims, settlements, judgments, costs or expenses, including reasonable costs of investigation, counsel fees, including allocated costs

-65-

of in-house counsel and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of its duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter, other than those arising out of the gross negligence or willful misconduct of the Escrow Agent (each as may be finally determined by a court of competent jurisdiction). The indemnity provided herein shall survive the termination of this Agreement and the termination and expiration of the Escrow Fund. The costs and expenses of enforcing this right of indemnification shall be paid half by the Parent and half by deduction from the Escrow Fund, unless there are not sufficient moneys remaining in the Escrow Fund, in which case Parent will pay such costs and expenses. The foregoing indemnities in this paragraph shall survive the resignation or substitution of the Escrow Agent or the termination of this Agreement.

(viii) The Escrow Agent may resign at any time upon giving not fewer than thirty (30) days written notice to the Parent and the Stockholder Representative; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent which shall be accomplished as follows: Parent and the Stockholder Representative shall use their commercially reasonable efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of Illinois or to petition a court of competent jurisdiction to appoint a successor escrow agent. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers, and duties of the predecessor escrow agent as if originally named as escrow agent. Upon appointment of a successor escrow agent, the Escrow Agent shall be discharged from any further duties and liability under this Agreement. The Escrow Agent shall be paid any outstanding fees and expenses prior to transferring assets to a successor escrow agent

(j) Fees. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by Parent in accordance with Exhibit F of this Agreement. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not provided for in this Agreement, or if the parties request a substantial modification of its terms (which modification is consented to by the Escrow Agent), or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to the Escrow Fund or its subject matter, the Escrow Agent shall be reasonably compensated for such extraordinary services and reimbursed for all costs, attorney’s fees and expenses occasioned by such default, delay, controversy or litigation.

(k) Consequential Damages. Anything to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

(l) Successor Escrow Agents. Any person into which the Escrow Agent in its individual capacity may be merged or converted or with which it may be consolidated, or any person resulting from any merger, conversion or consolidation to which the Escrow Agent in its individual

-66-

capacity shall be a party, or any person to which substantially all the business of the Escrow Agent in its individual capacity may be transferred, shall be the Escrow Agent thereunder without further act.

7.3 Stockholder Representative.

(a) In the event that the Merger is approved, effective upon such vote, and without further act of any Escrow Contributor or Company Rightholder, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ shall be appointed as the agent and attorney-in-fact, as the Stockholder Representative for and on behalf of the Escrow Contributors, to give and receive notices and communications, to authorize delivery or payment to Parent of Escrow Cash from the Escrow Fund in satisfaction of claims by Parent, to object to such payments, to agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to such claims, and to take all other actions that are either (i) necessary or appropriate in the judgment of the Stockholder Representative for the accomplishment of the foregoing or (ii) specifically mandated by the terms of this Agreement. Such agency may be changed by the Escrow Contributors from time to time upon not less than thirty (30) days prior written notice to Parent and the Escrow Agent; provided, however, that the Stockholder Representative may not be removed unless holders of a two-thirds interest of the Escrow Fund agree to such removal and to the identity of the substituted agent. Upon any change in the Stockholder Representative, such successor Stockholder Representative shall promptly provide the Escrow Agent with a signature specimen. Any vacancy in the position of Stockholder Representative may be filled by the holders of a majority in interest of the Escrow Fund. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall not receive compensation for its services. Notices or communications to or from the Stockholder Representative shall constitute notice to or from the Escrow Contributors.

ARTICLE VIII
TERMINATION, AMENDMENT AND WAIVER

8.1 Termination. Except as provided in Section 8.2 below, this Agreement may be terminated and the Merger abandoned at any time prior to the Closing Date:

(a) by mutual written consent executed and delivered by each party hereto and duly authorized by the Board of Directors of the Company and Parent;

(b) by either Parent or the Company if: (i) the Closing Date has not occurred by September 30, 2003 as a result of a condition to Closing not having been satisfied prior to such date or otherwise (provided that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any Party whose failure to fulfill any agreement or covenant required hereunder to be performed by such Party at or prior to the Effective Time has been the cause of, or resulted in, the failure of the Effective Time to occur on or before such date and such action or failure constitutes a breach of this Agreement); (ii) there shall be a final nonappealable order of a federal or state court in effect preventing consummation of the Merger; or (iii) there shall be any statute, rule, regulation or order enacted, promulgated or issued or deemed applicable to the Merger by any Governmental Body that would make consummation of the Merger illegal;

(c) by Parent if there shall be any action taken, or any statute, rule, regulation or order enacted, promulgated or issued or deemed applicable to the Merger, by any Governmental Body, which would: (i) prohibit Parent’s or the Company’s ownership or operation of any portion of the business of the Company or (ii) compel Parent or the Company to dispose of or hold separate, as a result of the Merger, any portion of the business or assets of the Company or Parent that would be material to the Company or Parent;

(d) by Parent if it is not in material breach of its representations, warranties, covenants or agreements under this Agreement and there has been a breach of any representation, warranty, covenant or agreement contained in this Agreement on the part of the Company and as a result of such breach the conditions set forth in Section 6.2(a) or 6.2(b), as the case may be, would not then be satisfied; provided, however, that if such breach is curable by the Company within fifteen (15) days through the exercise of its commercially reasonable efforts, then for so long as the Company continues to exercise such commercially reasonable efforts Parent may not terminate this Agreement under this Section 8.1(d) unless such breach is not cured within fifteen (15) days (but no cure period shall be required for a breach which by its nature cannot be cured); and

(e) by the Company if it is not in material breach of its representations, warranties, covenants or agreements under this Agreement and there has been a breach of any representation,

-68-

warranty, covenant or agreement contained in this Agreement on the part of Parent or Merger Sub and as a result of such breach the conditions set forth in Section 6.1(a) or 6.1(b), as the case may be, would not then be satisfied; provided, however, that if such breach is curable by Parent or Merger Sub within fifteen (15) days through the exercise of its commercially reasonable efforts, then for so long as Parent or Merger Sub continues to exercise such commercially reasonable efforts the Company may not terminate this Agreement under this Section 8.1(e) unless such breach is not cured within fifteen (15) days (but no cure period shall be required for a breach which by its nature cannot be cured).

8.2 Effect of Termination. Except as set forth in Sections 8.1(d) and 8.1(e), any termination of this Agreement under Section 8.1 above will be effective immediately upon the delivery of written notice of the terminating Party to the other parties hereto. In the event of the termination of this Agreement as provided in Section 8.1, this Agreement shall be of no further force or effect, except (a) as set forth in this Section 8.2 and Article IX (general provisions, including expenses), each of which shall survive the termination of this Agreement, and (b) nothing herein shall relieve any Party from liability for any willful breach of this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement.

8.3 Amendment. Except as is otherwise required by applicable law, prior to the Closing, this Agreement may be amended at any time by execution of an instrument in writing signed by Parent and the Company; provided, however, that (i) any amendment that affects the rights, duties or responsibilities of the Escrow Agent set forth in Section 7.2 hereunder may not be amended without the consent of the Escrow Agent, (ii) any amendment that affects the rights, duties or responsibilities of the Stockholder Representative set forth in Section 7.3 hereunder may not be amended without the consent of the Stockholder Representative and (iii) after the adoption of this Agreement by the Company Stockholders, no amendment may be made which reduces the Merger Cash or which effects any changes which would materially adversely affect the Company Stockholders without the further approval of the Company Stockholders.

8.4 Extension; Waiver. At any time prior to the Effective Time, Parent and Merger Sub, on the one hand, and the Company, on the other, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations of the other Party hereto, (b) waive any inaccuracies in the representations and warranties made to such Party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions for the benefit of such Party contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party.
