Except as set forth in the immediately preceding sentence, each Company Warrant shall continue

to have, and be subject to, the same terms and conditions as set forth in any agreements therefor immediately prior to the Effective Time.

Section 2.2 Options. At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any option to purchase shares of Company Common Stock, whether vested or not vested (each, an “Option” and collectively, the “Options”; Options granted under the Company’s Omnibus Stock and Incentive Plan (as such plan may be amended, supplemented or modified, the “1996 Plan”) are referred to herein as the “1996 Options” and Options granted under the Company’s 2002 Stock Option Plan (as such plan may be amended, supplemented or modified, the “2002 Plan”) are referred to herein as “2002 Options”), or any other Person, except as expressly provided herein:

(b) each Option outstanding immediately prior to the Effective Time with an exercise price per share less than the Common Stock Merger Consideration shall be canceled in exchange for the right to receive a payment in cash, without interest, equal to the product (such product, the “Option Merger Consideration”) of (i) the excess of (x) the Common Stock Merger Consideration over (y) the exercise price per share under such Option multiplied by (ii) the number of shares of Company Common Stock into which such Option is exercisable, which cash payment shall be reduced by any applicable withholding taxes. As soon as reasonably practicable following the Effective Time, but in no event more than ten (10) Business Days thereafter, the Surviving Corporation shall mail to each holder of an Option the applicable Option Merger Consideration.

Section 2.3 Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company (the “Paying Agent”) to make the payments of the funds to which holders of shares of Company Common Stock or shares of Company Preferred Stock shall be entitled pursuant to Section 2.1(c) or Section 2.1(d), respectively, and Parent shall enter into an agreement with the Paying Agent to provide for the foregoing on terms reasonably acceptable to the Company. At the Effective Time, Parent shall deposit with the Paying Agent all such funds in trust for the benefit of holders of shares of Company Common Stock and shares of Company Preferred Stock for timely payment hereunder in accordance with Section 2.1 and this Section 2.3 (such deposited funds, the “Exchange Fund”).

(b) Exchange Procedures. As promptly as practicable after the Effective Time but in no event more than five (5) Business Days thereafter, Parent shall cause the Paying Agent to mail to each holder of record of a certificate or certificates, which immediately prior to the Effective Time represented outstanding shares of Company Common Stock or Company Preferred Stock as of the Effective Time (the “Certificates”) whose shares were converted pursuant to Section 2.1(c) or 2.1(d) into the right to receive the Common Stock Merger

Consideration or the Preferred Stock Merger Consideration, as applicable, (i) a letter of transmittal and (ii) instructions for use in effecting the surrender of the Certificates in exchange for payment of the Common Stock Merger Consideration or the Preferred Stock Merger Consideration, as applicable. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive as promptly as practicable in exchange therefor, subject to subsection (f) below, the Common Stock Merger Consideration multiplied by the number of shares of Company Common Stock or the Preferred Stock Merger Consideration multiplied by the number of shares of Company Preferred Stock formerly represented by such Certificate, and in each case the Certificate so surrendered shall forthwith be canceled. Until surrendered as contemplated by this Section 2.3, each Certificate shall be deemed for all purposes at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration in cash as contemplated by Section 2.1 and this Section 2.3. No interest will be paid or accrue in any respect on any cash payable upon surrender of any certificate.

(c) Transfers of Ownership. If payment of the applicable Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other taxes required by reason of the payment of the applicable Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not applicable.

(d) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock or Company Preferred Stock on the records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of shares of Company Common Stock or Company Preferred Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares, except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged for the applicable Merger Consideration in the proper amount of cash as provided in this Article II.

(e) Return of Funds; No Liability. At any time following the six (6) month anniversary of the Effective Time, Parent or the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) remaining in the Exchange Fund which has not been disbursed to holders of Certificates as of such time, and thereafter, such holders shall be entitled to look only to Parent or the Surviving Corporation (subject to abandoned property, escheat or other similar laws) as general creditors thereof with respect to the payment of any applicable Merger Consideration that may be payable upon surrender of any Certificates such stockholder holds, as determined pursuant to this Agreement, without any interest thereon; provided that such holders shall have no greater rights against Parent than may be accorded to general creditors of Parent under applicable laws. Any portion of the Exchange Fund remaining unclaimed as of a date which is immediately prior to

such time as such amounts would otherwise escheat to or become property of any governmental entity shall, to the extent permitted by applicable law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto. Notwithstanding the foregoing, none of Parent, the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate for any applicable Merger Consideration properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f) Withholding Taxes. Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to a holder of shares of Company Common Stock or shares of Company Preferred Stock pursuant to the Merger such amounts as Parent, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign Tax law. To the extent amounts are so withheld by Parent, the Surviving Corporation or the Paying Agent, the withheld amounts shall be (i) timely paid to the appropriate Governmental Entity (as defined in Section 3.5) to whom such taxes are owed and (ii) treated for all purposes of this Agreement as having been paid to the holder of the shares in respect of which the deduction and withholding was made.

(g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

(h) Investment of Exchange Fund. The Exchange Fund shall be invested by the Paying Agent as directed by Parent; provided, however, that the terms and conditions of the investment shall be such as to permit the Paying Agent to make prompt payment of the Merger Consideration as necessary.

There is no labor dispute, strike, slowdown or work stoppage against the Company or any Subsidiary pending or, to the Company’s Knowledge, threatened which could reasonably be expected to have a Company Material Adverse Effect.

(b) Except as set forth on Schedule 3.14(b), none of the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby will (either alone or in conjunction with any other event) (A) result in any payment (including, without limitation, severance, unemployment compensation, parachute, sale bonus, stay bonus or other similar bonus, or otherwise) becoming due to any director or any employee of the Company or any Subsidiary from the Company or any Subsidiary under any Company Benefit Plan or otherwise, (B) significantly increase any benefits otherwise payable under any Company Benefit Plan or (C) result in any acceleration of the time of payment or vesting of any material benefits.

Each Insurance Policy is in full force and effect and is valid, outstanding and enforceable, and all premiums due thereon have been paid in full (except for premiums which have not become due), and no notice of cancellation or termination has been received with respect to any Insurance Policy which has not been replaced on substantially similar terms prior to the date of such cancellation. Schedule 3.15 sets forth a list of all material Insurance Policies maintained by the Company and its Subsidiaries as of the date hereof. Except as disclosed on Schedule 3.15, the Company, each Subsidiary and each Company P.C. has given timely notice to all applicable insurers of any material claims or any material potential claims reasonably likely to be covered under the Insurance Policies, as applicable, in accordance with the requirements of each such Insurance Policy.

Section 3.16 Tax Matters. Except as set forth on Schedule 3.16:

(a) The Company, each Subsidiary and each Company P.C. has prepared and duly and timely filed with the appropriate taxing authorities all material Tax Returns (as defined below) required to be filed through the date hereof. All such Tax Returns are complete and accurate in all material respects. All material Taxes (as defined below) due and owing by the Company, each Subsidiary and each Company P.C. on or before the date hereof have been paid. Neither the Company nor any of the Subsidiaries or Company P.C.s currently is the beneficiary of any extension of time within which to file any Tax Return. No claim has been made by an authority in a jurisdiction where any of the Company, the Subsidiaries or a Company P.C. does not file Tax Returns that it is or may be subject to taxation by that jurisdiction. As used herein, “Tax” means any federal, state, local or foreign income, gross receipts, license, payroll, employment, excise, severance, stamp, occupation, premium, windfall profits, environmental, customs duties, capital stock, franchise, profits, withholding, social security, unemployment, disability, real property, personal property, sales, use, transfer, registration, value added, alternative or add-on minimum, estimated, or other tax of any kind whatsoever, including

any interest, penalty, or addition thereto, whether disputed or not. As used herein, “Tax Returns” means any return, declaration, report, claim for refund, or information return or statement relating to Taxes, including any schedule or attachment thereto, and including any amendment thereof.

(b) No material deficiencies for Taxes against the Company, any Subsidiary or, to the Company’s Knowledge, any Company P.C. have been claimed, proposed or assessed by any taxing or other governmental authority that have not been settled, closed or otherwise resolved. There are no pending or, to the Company’s Knowledge, threatened audits, assessments or other actions for or relating to any Liability (as defined in Section 8.5) in respect of Taxes of the Company, any Subsidiary or, to the Company’s Knowledge, any Company P.C., and there are no matters under discussion with any governmental authorities, or to the Company’s Knowledge, with respect to Taxes that are likely to result in an additional Liability for Taxes with respect to the Company, any Subsidiary or, to the Company’s Knowledge, any Company P.C. The Company has delivered or made available to Parent complete and accurate copies of federal, state and local Tax Returns of the Company and each Subsidiary and their predecessors for the years ended December 31, 2001 and 2002, and complete and accurate copies of all examination reports and statements of deficiencies assessed against or agreed to by any of the Company and its Subsidiaries or any predecessors since December 31, 2000.

(c) The unpaid Taxes of the Company, each Subsidiary and each Company P.C. did not, as of the date of the Financial Statements, materially exceed the reserve for Tax Liability (as defined below) (excluding any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the balance sheets (rather than in any notes thereto) contained in the Financial Statements. Since the date of the Financial Statements, neither the Company nor any of the Subsidiaries or Company P.C.s has incurred any material Liability for Taxes outside the ordinary course of business or otherwise inconsistent with past custom and practice.

(iii) the Company shall have complied with Section 5.2(c) and shall not have breached in any material respect any of the other provisions set forth in this Section 5.2; and

(ii) “Superior Proposal” means any bona fide Takeover Proposal submitted to the Company or the Board of Directors (or any committee thereof) which did not result from a breach of this Section 5.2 and which the Board of Directors (or any committee thereof) concludes in good faith after (A) taking into account all relevant factors, facts and circumstances, including, without limitation, (x) the respective terms, conditions and structure of the transaction contemplated by this Agreement and the transaction contemplated by

(ii) if (A) the representations and warranties of Parent and Merger Sub set forth in this Agreement shall not be true and correct such that the condition set forth in Section 6.3(a) would not be satisfied as of the Closing Date, and (B) the underlying inaccuracy has continued without cure for a period of twenty (20) calendar days after Parent has delivered written notice of the inaccuracy to the Company;

(iii) if (A) Parent or Merger Sub shall have breached or failed to perform or comply with any covenant or agreement set forth in this Agreement such that the condition set forth in Section 6.3(b) would not be satisfied, and (B) the breach or failure has continued without cure for a period of twenty (20) calendar days after the Company has delivered written notice of the breach or breaches to Parent;

(iv) if (A) any of the stockholders of the Company set forth on Schedule 7.1(c)(4) shall have exercised appraisal rights in accordance with Section 262 of the DGCL, (B) such stockholder has not effectively withdrawn or otherwise lost its respective rights to appraisal with respect to its respective shares of Company Common Stock or Company Preferred Stock within forty-five (45) calendar days after the exercise of such appraisal rights, and (C) Parent and Merger Sub have not effectively waived the condition to the obligations of Parent and Merger Sub to effect the Merger set forth in Section 6.2(e) with respect to such stockholder within forty-five (45) calendar days after the exercise of such appraisal rights;

(d) by Parent:

(i) if (A) the representations and warranties of the Company set forth in this Agreement shall not be true and correct such that the condition set forth in Section 6.2(a) would not be satisfied as of the Closing Date, and (B) the inaccuracy has continued without cure for a period of twenty (20) calendar days after Parent has delivered written notice of the inaccuracy to the Company;

(iii) if (A) the Company shall have delivered to Parent any Material Adverse Effect Notice, and (B) the event giving rise to such notice has not been cured within twenty (20) calendar days after the event giving rise to the delivery of the Material Adverse Effect Notice.
