THE OFFER

SECTION 2.01 The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 9.01 and that none of the events set forth in Annex A hereto shall have occurred and be continuing, Purchaser shall commence the Offer as promptly as reasonably practicable (and in any event within ten Business Days) after the date hereof. The obligation of Purchaser to accept for payment Shares tendered pursuant to the Offer shall be subject to the condition (the

“Minimum Condition”) that at least the number of Shares that shall constitute a majority of the then outstanding Shares on an as-if-converted basis (including, without limitation, all Shares issuable upon the conversion of any convertible securities or upon the exercise of any options, warrants or rights (other than the Rights)) shall have been validly tendered and not withdrawn prior to the expiration of the Offer and also shall be subject to the satisfaction of each of the other conditions set forth in Annex A hereto. Purchaser expressly reserves the right (i) to waive any such condition, (ii) to increase the price per Share payable in the Offer and (iii) to make any other changes in the terms of the Offer; provided, however, that in the case of clause (iii) no other change may be made which (w) decreases the Per Share Amount payable in the Offer, (x) reduces the maximum number of Shares to be purchased in the Offer, (y) imposes conditions to the Offer in addition to those set forth in Annex A hereto or (z) is otherwise disadvantageous to the stockholders of the Company. Subject to the prior satisfaction or waiver by Parent or Purchaser of the Minimum Condition and the other conditions of the Offer set forth in Annex A hereto, Purchaser shall consummate the Offer in accordance with its terms and accept for payment and pay for all Shares tendered pursuant to the Offer as soon as practicable after Purchaser is legally permitted to do so under applicable law. Notwithstanding the foregoing, Purchaser may, without the consent of the Company, (i) extend the Offer beyond the scheduled expiration date, which shall be 20 Business Days following the commencement of the Offer, if, at the scheduled expiration of the Offer, any of the conditions to Purchaser’s obligation to accept for payment Shares, shall not be satisfied or waived, or (ii) extend the Offer for any period required by any rule, regulation or interpretation of the Securities and Exchange Commission (the “SEC”), or the staff thereof, applicable to the Offer. In addition, if, on the initial scheduled expiration date and each subsequent scheduled expiration date of the Offer, the sole condition or

conditions remaining unsatisfied are the failure of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), to have expired or been terminated and/or, if there is a Dispute that is pending or continuing, the Dispute Resolution Period shall not have expired , then Purchaser shall extend the Offer from time to time until the fifth Business Day after the later to occur of (i) expiration or termination of the applicable waiting period under the HSR Act or (ii) the expiration of the Dispute Resolution Period. Purchaser may, in its sole discretion, provide a “subsequent offering period” in accordance with Rule 14d-11 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Purchaser shall not terminate the Offer prior to any scheduled expiration date (as the same may be extended or required to be extended) without the written consent of the Company except in the event that Purchaser terminates this Agreement pursuant to Section 9.01. The Per Share Amount shall, subject to applicable withholding of taxes, be net to the seller in cash, upon the terms and subject to the conditions of the Offer. Purchaser shall pay for all Shares validly tendered and not withdrawn promptly following the acceptance of Shares for payment pursuant to the Offer. Notwithstanding the immediately preceding sentence and subject to the applicable rules of the SEC and the terms and conditions of the Offer, Purchaser expressly reserves the right to delay payment for Shares in order to comply in whole or in part with applicable laws. Any such delay shall be effected in compliance with Rule 14e-l(c) under the Exchange Act. If the payment equal to the Per Share Amount in cash (the “Merger Consideration”) is to be made to a person other than the person in whose name the surrendered certificate formerly evidencing Shares is registered on the stock transfer books of the Company, it shall be a condition of payment that the certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the person requesting such payment shall have paid all transfer and

other taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of the certificate surrendered, or shall have established to the satisfaction of Purchaser that such taxes either have been paid or are not applicable.

(b) As promptly as reasonably practicable on the date of commencement of the Offer, Purchaser shall file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, the “Schedule TO”) with respect to the Offer. The Schedule TO shall contain or shall incorporate by reference an offer to purchase (the “Offer to Purchase”) and forms of the related letter of transmittal and any related summary advertisement (the Schedule TO, the Offer to Purchase and such other documents, together with all supplements and amendments thereto, being referred to herein collectively as the “Offer Documents”). Parent, Purchaser and the Company agree to correct promptly any information provided by any of them for use in the Offer Documents that shall have become false or misleading and to correct any material omissions, and Parent and Purchaser further agree to take all steps necessary to cause the Schedule TO, as so corrected, to be filed with the SEC, and the other Offer Documents, as so corrected, to be disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities laws. The Company and its counsel shall be given a reasonable opportunity to review the Offer Documents before they are filed with the SEC, and Parent and Purchaser shall give due consideration to all the reasonable additions, deletions or changes suggested thereto by the Company and its counsel. In addition, Parent and Purchaser agree to provide the Company and its counsel with any comments, whether written or oral, that Parent, Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Offer Documents promptly after Parent’s or Purchaser’s, as the case may be, receipt of such comments, and any written or oral responses thereto. The Company and its

counsel shall be given a reasonable opportunity to review any such written responses and Parent and Purchaser shall give due consideration to all reasonable additions, deletions or changes suggested thereto by the Company and its counsel. If the Offer is terminated or withdrawn by Purchaser, or this Agreement is terminated prior to the purchase of Shares in the Offer, Parent and Purchaser shall promptly return, and shall cause any depository or paying agent, including the Paying Agent (as hereinafter defined), acting on behalf of Parent and Purchaser, to return all tendered Shares to the registered holders thereof.

The Company hereby consents to the inclusion in the Offer Documents of the recommendation of the Board described in the immediately preceding sentence, and the Company shall not withdraw or modify such recommendation in any manner adverse to Purchaser or Parent except as provided in Section 7.04(c).

advised by its directors and executive officers that they intend either to tender all Shares beneficially owned by them to Purchaser pursuant to the Offer or to vote such Shares in favor of the approval and adoption by the stockholders of the Company of this Agreement and the Transactions.

(b) As promptly as reasonably practicable on the date of commencement of the Offer, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, the “Schedule 14D-9”) containing, except as provided in Section 7.04(c), the recommendation of the Board described in Section 2.02(a), and shall disseminate the Schedule 14D-9 to the extent required by Rule 14d-9 promulgated under the Exchange Act and any other applicable federal securities laws. The Company, Parent and Purchaser agree to correct promptly any information provided by any of them for use in the Schedule 14D-9 which shall have become false or misleading and to correct any material omissions, and the Company further agrees to take all steps necessary to cause the Schedule 14D-9, as so corrected, to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities laws. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review the Schedule 14D-9 before it is filed with the SEC and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel. In addition, the Company agrees to provide Parent, Purchaser and their counsel with any comments, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after the Company’s receipt of such comments, and any written or oral responses thereto. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall

give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel.

(c) The Company shall promptly furnish Parent or Purchaser with mailing labels containing the names and addresses of all record holders of Shares and with security position listings of Shares held in stock depositories, each as of a recent date, together with all other available listings and computer files containing names, addresses and security position listings of record holders and beneficial owners of Shares. The Company shall promptly furnish Purchaser with such additional information, including, without limitation, updated listings and computer files of stockholders, mailing labels and security position listings, and such other assistance in disseminating the Offer Documents to holders of Shares as Parent or Purchaser may reasonably request. Subject to the requirements of applicable law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer or the Merger, Parent and Purchaser shall hold in confidence the information contained in such labels, listings and files, shall use such information only in connection with the Transactions, and, if this Agreement shall be terminated in accordance with Section 9.01, shall deliver to the Company all copies of such information then in their possession.

SECTION 2.03 Directors. Promptly upon the purchase of and payment for any Shares by Parent or Purchaser pursuant to the Offer (provided the Shares so purchased represent at least a majority of the Shares issued and outstanding), Parent shall be entitled to designate such number of directors, rounded to the nearest whole number, on the Board as is equal to the product of the total number of directors on the Board (giving effect to the directors designated by Parent pursuant to this sentence) multiplied by the percentage that the number of Shares so

accepted for payment bears to the total number of Shares then outstanding. In furtherance of Parent’s rights under this Section 2.03, the Company shall, upon Parent or Purchaser’s request, use all reasonable efforts promptly either to increase the size of the Board or to secure the resignations of such number of its incumbent directors, or both, as is necessary to enable Parent’s designees to be so elected to the Board, and shall take all actions available to the Company to cause Parent’s designees to be so elected. At such time, the Company shall also cause persons designated by Parent to have appropriate representation on (i) each committee of the Board, (ii) each board of directors (or similar body) of each Subsidiary and (iii) each committee (or similar body) of each such board. The Company shall promptly take all actions required pursuant to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order to fulfill its obligations under this Section 2.03, including mailing to stockholders (as part of the Schedule 14D-9 or otherwise) the information required by such Section 14(f) and Rule 14f-1 as is necessary to enable Parent’s designees to be elected to the Board (provided that Purchaser shall have provided to the Company on a timely basis all information required to be included with respect to Purchaser’s designees). In the event that Parent’s designees are elected to the Board, until the Effective Time (as defined below), the Board shall have at least three directors who are directors on the date of this Agreement (the “Original Directors”); provided that, in such event, if the number of Original Directors is reduced below three for any reason whatsoever, any remaining Original Directors (or Original Director, if there be only one remaining) shall be entitled to designate persons to fill such vacancies who shall be deemed to be Original Directors for purposes of this Agreement or, if no Original Director then remains, the other directors shall designate three persons to fill such vacancies who shall not be stockholders, affiliates or associates of Parent or Purchaser, and such persons shall be deemed to be Original Directors for

purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, if Parent’s designees are elected to the Board before the Effective Time, the affirmative vote of a majority of the Original Directors shall be required for the Company to (a) amend or terminate this Agreement or agree or consent to any amendment or termination of this Agreement, (b) exercise or waive any of the Company’s rights, benefits or remedies hereunder, (c) extend the time for performance of Parent’s and Purchaser’s respective obligations under this Agreement, (d) take any other action by the Board under or in connection with this Agreement, (e) amend the Certificate of Incorporation or Bylaws of the Company or (f) approve any other action by the Company which could adversely affect the interests of the stockholders of the Company (other than Parent, Purchaser and their affiliates (other than the Company and its Subsidiaries)), with respect to the Transactions.

SECTION 3.01 The Merger. Upon the terms and subject to the conditions set forth in Article VIII, and in accordance with Delaware Law, Purchaser shall be merged with and into the Company.

SECTION 3.02 Effective Time; Closing. As promptly as practicable after the satisfaction or, if permissible, waiver of the conditions set forth in Article VIII, the parties hereto shall cause the Merger to be consummated by filing this Agreement or a certificate of merger or certificate of ownership and merger with the Secretary of State of the State of Delaware (the “Certificate of Merger”), in such form as is required by, and executed in accordance with, the relevant provisions of Delaware Law (the date and time of such filing being the “Effective Time”). Prior to such filing, a closing shall be held at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, Four Embarcadero Center, San Francisco, CA 94111, or such other place

as the parties shall agree, for the purpose of confirming the satisfaction or waiver, as the case may be, of the conditions set forth in Article VIII.

SECTION 3.03 Effect of the Merger. As a result of the Merger, the separate corporate existence of Purchaser shall cease and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”). At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of the Company and Purchaser shall vest in the Surviving Corporation, and all debts, liabilities, obligations, restrictions, disabilities and duties of the Company and Purchaser shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Corporation.

SECTION 3.04 Certificate of Incorporation; By-laws.

(a) At the Effective Time, subject to Sections 7.06(b) and (c), the Certificate of Incorporation of Purchaser, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by law and such Certificate of Incorporation; provided, however, that, at the Effective Time, Article I of the Certificate of Incorporation of the Surviving Corporation shall be amended to read as follows: “The name of the corporation is D&K Healthcare Resources, Inc.”

(b) Unless otherwise determined by Parent prior to the Effective Time, and subject to Sections 7.06(b) and (c), the By-laws of Purchaser, as in effect immediately prior to the Effective Time, shall be the By-laws of the Surviving Corporation until thereafter amended as provided by law, the Certificate of Incorporation of the Surviving Corporation and such By-laws.

SECTION 3.05 Directors and Officers. The directors of Purchaser immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and By-laws of the Surviving Corporation, and the officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal.

SECTION 3.06 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Purchaser, the Company or the holders of any of the following securities:

(a) Each Share issued and outstanding immediately prior to the Effective Time (other than any Shares to be canceled pursuant to Section 3.06(b) and any Dissenting Shares (as hereinafter defined), but including restricted Shares (whether vested or unvested) issued under Company Stock Plans (defined below)) shall be canceled and shall be converted automatically into the right to receive an amount equal to the Merger Consideration payable, without interest, to the holder of such Share, upon surrender, in the manner provided in Section 3.09, of the certificate that formerly evidenced such Share;

(b) Each Share held in the treasury of the Company and each Share owned by Purchaser, Parent or any direct or indirect wholly owned subsidiary of Parent or of the Company immediately prior to the Effective Time shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto; and

(c) Each share of common stock, par value $0.001 per share, of Purchaser issued and outstanding immediately prior to the Effective Time shall be converted into and

exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

SECTION 3.07 Employee Stock Options. Effective as of the Effective Time, the Company shall (i) terminate the Company’s Amended and Restated 2001 Long Term Incentive Plan, its 1992 Long Term Incentive Plan and its 1993 Stock Option Plan, each as amended through the date of this Agreement (the “Company Stock Plans”), and (ii) cancel, at the Effective Time, each outstanding option to purchase shares of Company Common Stock granted under the Company Stock Plans or otherwise (each, a “Company Stock Option”) that is outstanding and unexercised as of such date. Each holder of a Company Stock Option that is outstanding and unexercised at the Effective Time (whether or not such option has vested) shall be entitled to receive from the Surviving Corporation immediately after the Effective Time, in exchange for the cancellation of such Company Stock Option, an amount in cash equal to the excess, if any, of (x) the Per Share Amount over (y) the per share exercise price of such Company Stock Option, multiplied by the number of shares of Company Common Stock subject to such Company Stock Option as of the Effective Time. Any such payment shall be subject to all applicable federal, state and local tax withholding requirements. To the extent that amounts are so withheld by Parent, Purchaser, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent. The Company shall take all necessary action to approve the disposition of the Company Stock Options in connection with the Transactions to the extent necessary to exempt such dispositions and acquisitions under Rule l6b-3 of the Exchange Act,

and shall take all necessary action to effect the treatment of the Company Stock Plans and Company Stock Options set forth in this Section 3.07, including obtaining all necessary consents.

SECTION 3.08 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary, Shares that are outstanding immediately prior to the Effective Time and that are held by stockholders who shall have neither voted in favor of the Merger nor consented thereto in writing and who shall have demanded properly in writing appraisal for such Shares in accordance with Section 262 of Delaware Law (collectively, the “Dissenting Shares”) shall not be converted into, or represent the right to receive, the Merger Consideration. Such stockholders shall be entitled to receive payment of the appraised value of such Shares held by them in accordance with the provisions of such Section 262, except that all Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such Shares under such Section 262 shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender, in the manner provided in Section 3.09, of the certificate or certificates that formerly evidenced such Shares.

(b) The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by the Company relating to rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under Delaware Law. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

SECTION 3.09 Surrender of Shares; Stock Transfer Books.

(a) Prior to the Effective Time, Purchaser shall designate a bank or trust company to act as agent (the “Paying Agent”) for the holders of Shares to receive the funds to which holders of Shares shall become entitled pursuant to Section 3.06(a). For purposes of determining the amount of Merger Consideration to be so deposited, Parent and Purchaser shall assume that no stockholder of the Company will perfect any right to appraisal of his, her or its Shares. Such funds shall be invested by the Paying Agent as directed by Parent or the Surviving Corporation, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Shares. Earnings from such investments shall be the sole and exclusive property of Parent and the Surviving Corporation, and no part of such earnings shall accrue to the benefit of holders of Shares.

(b) Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each person who was, at the Effective Time, a holder of record of Shares entitled to receive the Merger Consideration pursuant to Section 3.06(a) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing such Shares (the “Certificates”) shall pass, only upon proper delivery of the Certificates to the Paying Agent) and instructions for use in effecting the surrender of the Certificates pursuant to such letter of transmittal. Upon surrender to the Paying Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly evidenced by such Certificate, and such Certificate shall then be canceled. No interest shall accrue or be paid on the Merger

Consideration payable upon the surrender of any Certificate for the benefit of the holder of such Certificate. If the payment equal to the Merger Consideration is to be made to a person other than the person in whose name the surrendered certificate formerly evidencing Shares is registered on the stock transfer books of the Company, it shall be a condition of payment that the certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the person requesting such payment shall have paid all transfer and other taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of the certificate surrendered, or shall have established to the satisfaction of Purchaser that such taxes either have been paid or are not applicable.

(c) At any time following the sixth month after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of Shares (including, without limitation, all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Share for any Merger Consideration delivered in respect of such Share to a public official pursuant to any abandoned property, escheat or other similar law.

(d) At the close of business on the day of 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 on the records of the Company. From and after the Effective Time, the

holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or by applicable law.

SECTION 3.10 Subsequent Actions. If at any time after the Effective Time the Surviving Corporation shall determine, in its sole discretion, or shall be advised, that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of the Company or Purchaser acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of either the Company or Purchaser, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of each of such corporations or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

ARTICLE IV

Except as set forth in the Company’s disclosure schedule delivered to Parent prior to the execution of this Agreement (the “Disclosure Schedule”), the Company represents and warrants to Parent and Purchaser as set forth below. Each disclosure set forth in the Disclosure Schedule is identified by reference to, or has been grouped under a heading referring to, a specific individual section of this Agreement and disclosure made pursuant to any section thereof shall be deemed to be disclosed on each of the other sections of the Disclosure Schedule to the extent the

applicability of the disclosure to such other section is reasonably apparent on its face from the disclosure made.

SECTION 4.01 Organization and Qualification; Subsidiaries.

(a) Each of the Company and each subsidiary of the Company (“Subsidiary”) is a corporation duly organized, validly existing and, to the extent applicable, in good standing under the laws of the jurisdiction of its incorporation and has the requisite corporate power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted. The Company and each Subsidiary 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 business makes such qualification or licensing necessary, except where the failure to have such good standing, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. Section 4.01(a) of the Disclosure Schedule lists jurisdictions in which the Company and each Subsidiary is qualified as a foreign corporation.

(b) Except as disclosed in Section 4.01(b) of the Disclosure Schedule, the Company does not directly or indirectly own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any corporation, partnership, joint venture or other business association or entity.

SECTION 4.02 Certificate of Incorporation and By-laws. The Company has heretofore furnished to Parent a complete and correct copy of the Certificate of Incorporation and the By-laws or equivalent organizational documents, each as amended to date, of the Company and each Subsidiary. Such Certificate of Incorporation, By-laws or equivalent organizational documents are in full force and effect. Neither the Company nor any Subsidiary is in violation of

any of the provisions of its Certificate of Incorporation, By-laws or equivalent organizational documents.

SECTION 4.03 Capitalization. The authorized capital stock of the Company consists of 25,000,000 Shares and 1,000,000 shares of preferred stock, no par value (“Company Preferred Stock”). As of the date hereof, (a) 14,260,856 Shares are issued and outstanding, all of which are duly authorized, validly issued, fully paid and nonassessable, (b) 1,249,300 Shares are held in the treasury of the Company, (c) no Shares are held by any Subsidiary or affiliate of the Company, (d) 49,230 Shares are reserved for future issuance pursuant to employee stock options, restricted stock or any stock or stock-related incentive rights to be granted pursuant to the Company Stock Plans, (e) 1,510,666 Shares are issuable upon the exercise of existing options to purchase Shares, and (f) 297,970 Shares are subject to outstanding restricted stock agreements. As of the date hereof, no shares of Company Preferred Stock are issued and outstanding. Except as set forth in this Section 4.03 and Section 4.03 of the Disclosure Schedule, and except for the rights (the “Rights”) issued pursuant to the Rights Agreement, dated as of November 12, 1998 (the “Rights Agreement”), between the Company and Harris Trust and Savings Bank, as rights agent, there are no options, warrants or other rights, agreements, arrangements or commitments of any character relating to the issued or unissued capital stock of the Company or any Subsidiary or obligating the Company or any Subsidiary to issue or sell any shares of capital stock of, or other equity interests in, or any other security exercisable or exchangeable for, or convertible into, any such shares or other equity interests in, the Company or any Subsidiary. All Shares subject to issuance as aforesaid, upon issuance on the terms and conditions specified in the instruments pursuant to which they are issuable, will be, when issued, duly authorized, validly issued, fully paid and nonassessable. There are no outstanding contractual obligations,

arrangements or commitments of any character of the Company or any Subsidiary to repurchase, redeem or otherwise acquire any Shares, any other capital stock of, or other equity interest in the Company or any Subsidiary or to provide funds to, or make any investment (in the form of a loan, capital contribution or otherwise) in, any Subsidiary or any other person. There are no bonds, debentures, notes or other indebtedness of the Company or any Subsidiary having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which stockholders of the Company or any Subsidiary may vote. Each outstanding share of capital stock of each Subsidiary is duly authorized, validly issued, fully paid and nonassessable, and all such shares are owned by the Company or another Subsidiary free and clear of all security interests, liens, claims, pledges, options, rights of first refusal, agreements, limitations on the Company’s or any Subsidiary’s voting rights, charges and other encumbrances of any nature whatsoever.

SECTION 4.04 Authority Relative to This Agreement. The Company has all necessary corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the Transactions. The execution and delivery of this Agreement by the Company and the consummation by the Company of the Transactions have been duly and validly authorized by all necessary corporate action, and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the Transactions (other than, with respect to the Merger, the approval and adoption of this Agreement by the holders of a majority of the then-outstanding Shares, if and to the extent required by applicable law, and the filing and recordation of appropriate merger documents as required by Delaware Law). This Agreement has been duly executed and delivered by the Company and, assuming the due authorization, execution and delivery by Parent and Purchaser,

constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that (i) such enforcement may be subject to applicable bankruptcy, insolvency or other similar laws, now or hereafter in effect, affecting creditors’ rights generally and (ii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. Assuming the accuracy of the representation and warranty set forth in Section 5.08, the action taken by the Board in approving this Agreement and the Transactions is sufficient to render inapplicable to this Agreement and the Transactions the restrictions on business combinations contained in Section 203 of the Delaware Law.

SECTION 4.05 No Conflict; Required Filings and Consents.

(a) The execution and delivery of this Agreement by the Company do not, and the performance of this Agreement by the Company will not, (i) conflict with or violate the Certificate of Incorporation or By-laws or equivalent organizational documents of the Company or any Subsidiary, (ii) assuming all consents, approvals, authorizations and other actions described in Section 4.05(b) have been obtained or taken, conflict with or violate any federal, state, local or foreign statute, law, ordinance, regulation, rule, agency requirement, code, executive order, injunction, judgment, decree, arbitral award or other order (“Law”) applicable to the Company or any Subsidiary or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) result in any breach of or constitute a default (or an event which, with notice or lapse of time or both, would become a default) under, or give to others any right of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or other encumbrance on any property or asset of the Company or any Subsidiary pursuant to,

any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation, except, with respect to clauses (ii) and (iii), (1) as set forth in Section 4.05 of the Disclosure Schedule and (2) for any such conflicts, violations, breaches, defaults or other occurrences which, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the Offer or the Merger or otherwise would not reasonably be expected to prevent or materially delay the Company from performing its obligations under this Agreement and would not reasonably be expected to have a Material Adverse Effect.

(b) The execution and delivery of this Agreement by the Company do not, and the performance of this Agreement by the Company will not, require any consent, approval, authorization or permit of, or filing with or notification to, any United States federal, state, county, foreign or local governmental, regulatory or administrative authority, agency, instrumentality or commission (a “Governmental Entity”) or any court, tribunal, or judicial or arbitral body (together with a Governmental Entity, a “Governmental Authority”), except for (i) compliance with any applicable requirements of the Exchange Act, (ii) any filings as may be required under Delaware Law in connection with the Merger, (iii) filings permits, authorizations, consents and approvals as may be required under the HSR Act, (iv) the filing with the SEC and the Nasdaq National Market, Inc. (“Nasdaq”) of (A) the Schedule 14D-9, (B) the Proxy Statement (as hereinafter defined) if stockholder approval is required by law, (C) the information required by Rule 14f-1 under the Exchange Act and (D) such reports under Section 13(a) of the Exchange Act as may be required in connection with this Agreement and the Transactions, (v) such filings and approvals as may be required by any applicable state securities or blue sky laws, and (vi) where the failure to obtain such consents, approvals, authorizations or permits, or

to make such filings or notifications, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the Offer or the Merger, or otherwise would not reasonably be expected to prevent or materially delay the Company from performing its obligations under this Agreement, and would not reasonably be expected to have a Material Adverse Effect.

SECTION 4.06 Permits; Compliance.

(a) Except as set forth in Part I of Section 4.06 of the Disclosure Schedule, each of the Company and each Subsidiary is in possession of all franchises, grants, authorizations, licenses, permits, easements, variances, exceptions, consents, certificates, approvals and orders of any Governmental Authority necessary for each of the Company and the Subsidiaries to own, lease and operate its properties and to carry on its business as it is now being conducted (the “Permits”), except where the failure to have, or the suspension or cancellation of, any of the Permits, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the Offer or the Merger or otherwise would not reasonably be expected to prevent or materially delay the Company from performing its obligations under this Agreement and would not reasonably be expected to have a Material Adverse Effect. As of the date hereof, no suspension or cancellation of any of the Permits, is pending or, to the knowledge of the Company, threatened, except where the failure to have, or the suspension or cancellation of, any of the Permits, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the Offer or the Merger or otherwise would not reasonably be expected to prevent or materially delay the Company from performing its obligations under this Agreement and would not reasonably be expected to have a Material Adverse Effect. Except as set forth in Part II of Section 4.06 of the Disclosure

Schedule, neither the Company nor any Subsidiary is in conflict with, in default under, or in breach or violation of, (a) any Law applicable to the Company or any Subsidiary or by which any property or asset of the Company or any Subsidiary is bound or affected, or (b) any Contract to which the Company or any Subsidiary is a party or by which the Company or any Subsidiary or any property or asset of the Company or any Subsidiary is bound, except for any such conflicts, defaults, breaches or violations that, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the Offer or the Merger or otherwise would not reasonably be expected to prevent or materially delay the Company from performing its obligations under this Agreement and would not reasonably be expected to have a Material Adverse Effect.

SECTION 4.07 SEC Filings; Financial Statements.

(a) Except as set forth in Section 4.07(a) of the Disclosure Schedule, the Company has timely filed all forms, reports and documents (including exhibits and other information incorporated therein) required to be filed by it with the SEC since June 30, 2002 (the forms, reports and other documents referred to above being, collectively, the “SEC Reports”). The SEC Reports (i) were prepared in accordance with the requirements of the Securities Act of 1933, as amended (the “Securities Act”) and the rules and regulations promulgated thereunder or the Exchange Act and in the rules and regulations promulgated thereunder, as the case may be, applicable to such SEC Reports, (ii) the SEC Reports, as of their respective dates (and, if amended or superseded by a filing prior to the date of this Agreement or the expiration of the Offer, then on the date of such filing), complied in all material respects with all requirements of the Securities Act or the Exchange Act, as the case may be, and, in each case, the rules and regulations promulgated thereunder, applicable to such SEC Reports and (iii) did not, at the time

they were filed, or, if amended, as of the date of such amendment, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. No Subsidiary is required to file any form, report or other document with the SEC. The SEC Reports included or, with respect to such reports filed after the date hereof, will include all certificates required to be included therein pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended (the “SOX Act”), and the internal control report and attestation of the Company’s outside auditors required by Section 404 of the SOX Act.

(b) The Company is in compliance in all material respects with the applicable provisions of the SOX Act and the applicable listing and governance rules and regulations of the Nasdaq. The Company has implemented disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) to ensure that material information relating to the Company is made known to the management of the Company by others within those entities. The Company and each Subsidiary (i) makes and keeps accurate books and records and (ii) maintains internal accounting controls which provide reasonable assurance that (a) transactions are executed in accordance with management’s general or specific authorization, (b) transactions are recorded as necessary to permit preparation of its financial statements in conformity with GAAP and to maintain accountability for its assets, (c) access to its assets is permitted only in accordance with management’s general or specific authorization and (d) the reported accounting for its assets and liabilities is compared with existing assets and liabilities at reasonable intervals. The Company has prepared a plan to comply with the requirements of Section 404 of the SOX Act on the date by which it must comply with such requirements.

Except as set forth in Section 4.07(b) of the Disclosure Schedule, the Company is not aware of any reason it will not comply with the requirements of Section 404 of the SOX Act on the applicable compliance date and has no knowledge of any “significant deficiency” or “material weakness” in the Company’s internal controls.

(a) The Company shall, and shall cause its Subsidiaries and each of their respective affiliates, directors, officers, employees, agents and representatives (including any investment banker, financial advisor, attorney, accountant or other representative retained by the Company or any of its Subsidiaries) to immediately cease any discussions or negotiations with any other parties that may be ongoing with respect to the possibility or consideration of any Acquisition Proposal. From the date of this Agreement through the Effective Time, the Company shall not, nor shall it permit any of its Subsidiaries to, nor shall it authorize or permit any of its or its Subsidiaries’ directors, officers or employees or any investment banker, financial

advisor, attorney, accountant or other representative retained by it or any of its Subsidiaries to, directly or indirectly through another person, (i) solicit, initiate or encourage (including by way of furnishing information or assistance), or take any other action designed to facilitate or encourage any inquiries or the making of any proposal that constitutes, or is reasonably likely to lead to, any Acquisition Proposal, (ii) participate in any discussions or negotiations regarding, or provide any nonpublic information or data to any person relating to, any Acquisition Proposal or (iii) make or authorize any statement, recommendation or solicitation in support of, or execute or enter into, or propose to execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement related to, any Acquisition Proposal.

(b) Notwithstanding the foregoing, until the consummation of the Offer the Board shall be permitted to engage in discussions and negotiations with, or provide nonpublic information or data to, any person in response to an unsolicited, bona fide written Acquisition Proposal by such person first made after the date of this Agreement that did not result from a breach of this Section 7.04 which the Board concludes in good faith (after consultation with outside counsel and its financial advisor) constitutes or would reasonably be expected to lead to a Superior Proposal, only (1) if and only to the extent that the Board reasonably determines in good faith (after consultation with outside legal counsel) that it is required to do so in order to comply with its fiduciary duties under applicable law, (2) if, prior to furnishing such information to or entering into negotiations or discussions with such person, the Company enters into a

confidentiality agreement with such person having provisions that are no less restrictive to such person than those applicable to Parent and contained in the Confidentiality Agreement and (3) if the Company complies with all of the terms of this Section 7.04. The Company shall notify Parent as promptly as practicable (and in no event later than 24 hours) after receipt of any Acquisition Proposal, or any request for nonpublic information relating to the Company or any of its Subsidiaries by any person or that informs the Company or any of its Subsidiaries that it is considering making, or has made, an Acquisition Proposal, or any inquiry from any person seeking to have discussions or negotiations with the Company relating to a possible Acquisition Proposal. Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the person making the Acquisition Proposal, inquiry or request and the material terms and conditions of any inquiries, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). The Company shall also notify Parent, in writing, as promptly as practicable (and in no event later than 24 hours prior to) any meeting of the Board called to consider any Acquisition Proposal or any such inquiry or to consider providing nonpublic information to any person. The Company shall notify Parent, in writing, of any decision of the Board as to whether to consider such Acquisition Proposal or inquiry or to enter into discussions or negotiations concerning any Acquisition Proposal or to provide nonpublic information or data to any person, which notice shall be given as promptly as practicable after such meeting (and in any event no later than 24 hours after such determination was reached and 24 hours prior to entering into any discussions or negotiations or providing any nonpublic information or data to any person). The Company agrees that it shall keep Parent informed of the status and terms of any such inquiries, proposals, offers, discussions or negotiations on a current basis, including by: delivering a copy of all documentation and

correspondence relating thereto promptly upon receipts thereof, delivering to Parent the information delivered to such person to the extent such information was not previously provided to Parent and providing Parent with 24 hours prior notice of each Board meeting called to discuss or consider any Acquisition Proposal.

(c) The Board shall not (i) withdraw, modify or change, in a manner adverse to Parent or Purchaser, the Board’s recommendation to accept the Offer or (ii) approve, enter into or recommend that stockholders approve or accept a Superior Proposal unless, prior to the consummation of the Offer, the Board determines in good faith after consultation with the Company’s financial advisors and outside legal counsel, that an Acquisition Proposal constitutes a Superior Proposal and that failure to do so would result in a reasonable likelihood of a breach of the fiduciary duties of the Board under applicable law, in which case, the Board may (subject to this and the following sentences) withdraw, modify or change, in a manner adverse to Parent or Purchaser, the Board’s recommendation and take and disclose to the stockholders of the Company a position with respect to the Superior Proposal and, to the extent applicable, comply with Rule 14e-2 promulgated under the Exchange Act with respect to such Superior Proposal by disclosing such withdrawn, modified or changed Board recommendation and any recommendation with respect to such Superior Proposal in connection with a tender or exchange offer for the Company’s securities, provided that: (1) the Company shall have notified Parent, in writing no later than five (5) Business Days’ prior to the Board’s withdrawing or changing its recommendation, that the Board has determined (after consultation with its financial advisors and outside legal counsel) that the Acquisition Proposal constitutes a Superior Proposal and that Board intends to withdraw or change its recommendation with respect to the Offer or approve, recommend, or enter into an agreement with respect to, the Superior Proposal, which notice shall

include the identity of the person making the Superior Proposal and a copy of the final terms of the Superior Proposal; (2) during such five (5) Business Day period, the Board shall have given due consideration to any proposals made by Parent to adjust the Offer and the Transactions; and (3) the Board shall have determined (A) after consultation with its financial advisor, that any such proposal made by or on behalf of Parent is less favorable to the stockholders of the Company than the Superior Proposal and (B) after consultation with outside legal counsel, it would result in a reasonable likelihood that the Board would breach its fiduciary duties to the stockholders of the Company under applicable law if it failed to withdraw or change its recommendation with respect to the Offer and the Transactions or failed to approve or enter into the Superior Proposal or recommend that the stockholders of the Company accept or approve the Superior Proposal. The Board shall not, in connection with any such withdrawal, modification or change of its recommendation, take any action to change the approval of the Board for purposes of causing any state takeover statute or other state law or the Rights Agreement to be applicable to the transactions contemplated hereby, including this Agreement, the Offer and the Merger, provided, however, that this sentence shall not prohibit the Company from withdrawing, modifying or changing its recommendation or approving or entering into or recommending any Superior Proposal under the circumstances and subject to the conditions set forth in this Section 7.04(c). Nothing contained in this Section 7.04 shall prohibit the Company or its Subsidiaries from taking and disclosing to its stockholders a position as required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act; provided, however, that compliance with such rules shall not in any way limit or modify the effect that any action taken pursuant to such rules has under any other provision of this Agreement.

(d) The Company agrees that (i) it will, and will cause its Subsidiaries and their respective officers, directors, agents, representatives and advisors to, cease immediately and terminate any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal, and (ii) it will not release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which it or any its Subsidiaries is a party with respect to any Acquisition Proposal.

SECTION 7.05 Employee Benefits Matters. Parent agrees that from and after the Effective Time, Parent shall cause the Surviving Corporation to honor in accordance with their terms the employment contracts of the Company set forth in Section 7.05 of the Disclosure Schedule. Employees of the Surviving Corporation and its subsidiaries will be provided with employee benefits that are in the aggregate no less favorable than those employee benefits that are provided to similarly situated employees of Parent and its subsidiaries. Employees of the Company or any Subsidiary shall receive credit for purposes of eligibility to participate and vesting (but not for benefit accruals, determination of levels of benefits or any other purposes) under any employee benefit plan, program or arrangement established or maintained by the Surviving Corporation or any of its subsidiaries for service accrued or deemed accrued prior to the Effective Time with the Company or any Subsidiary to the same extent such service was taken into account for such purposes under comparable Plans prior to the Effective Time; provided, however, that such crediting of service shall not operate to duplicate any benefit or the funding of any such benefit. Notwithstanding the foregoing, nothing in this Section 7.05 nor any other provision of this Agreement shall limit the ability or right of the Parent or the Surviving Corporation and their subsidiaries to terminate the employment of any of their respective employees after the Effective Time or to terminate or amend any Plan. Prior to the Effective

Time, if requested by Parent, the Company shall terminate the Company’s Code Section 401(k) plan (the “Company 401(k) Plan”) in accordance with all provisions of applicable law, and each participant in the Company 401(k) Plan shall have the right to receive a distribution of such participant’s account balance in the Company 401(k) Plan (subject to, and in accordance with, the provisions of the plan and applicable law).

SECTION 7.06 Directors’ and Officers’ Indemnification and Insurance.

(a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including any such claim, action, suit, proceeding or investigation in which any person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries (the “Indemnified Parties”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director or officer of the Company or any of its Subsidiaries or (ii) this Agreement or any of the Transactions, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate and use their best efforts to defend against and respond thereto. It is understood and agreed that after the Effective Time, Parent shall and shall cause the Surviving Corporation to, indemnify and hold harmless, to the fullest extent permitted by law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including advances of reasonable attorney’s fees and expenses prior to the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by law upon receipt of any undertaking required by applicable law), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation, and in the event of any such threatened or actual claim,

action, suit, proceeding or investigation (whether asserted or arising before or after the Effective Time), the Indemnified Parties may retain counsel reasonably satisfactory to them after consultation with Parent; provided, however, that: (1) Parent shall have the right to assume the defense thereof and upon such assumption Parent shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Parent elects not to assume such defense or counsel for the Indemnified Parties reasonably advises that there are (under applicable standards of professional conduct) issues which raise conflicts of interest between Parent and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them after consultation with Parent, and Parent shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties; (2) Parent shall in all cases be obligated pursuant to this paragraph to pay for only one firm or counsel and any necessary local counsel for all Indemnified Parties except that if counsel for the Indemnified Parties reasonably advises that there are (under applicable standards of professional conduct) issues which raise conflicts of interest among one or more of the Indemnified Parties, Parent will be obligated to pay for separate counsel such Indemnified Parties as to which there are conflicts; (3) Parent shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld or delayed); and (4) Parent shall have no obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law. It is agreed and understood that Parent’s agreement to provide the indemnification contemplated hereunder is no way intended to expand the scope of the

indemnification obligations beyond that which a corporation would be permitted to provide to its own officers or directors under Delaware Law. Any Indemnified Party wishing to claim Indemnification under this Section 7.06, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Parent thereof, provided that the failure to so notify Parent shall not affect the obligations of Parent under this Section 7.06 except to the extent such failure to notify prejudices Parent. Parent’s obligations under this Section 7.06 shall continue in full force and effect for a period of six (6) years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim (a “Claim”) asserted or made within such period shall continue until the final disposition of such Claim.

(b) Parent shall cause the Surviving Corporation to maintain in effect for a period of six (6) years from the Effective Time the current directors’ and officers’ liability insurance policy maintained by the Company (provided that Parent may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous than such current policy) covering the persons serving as officers and directors of the Company on the date of this Agreement with respect to acts or omissions occurring prior to the Effective Time which were committed by such officers and directors in their capacity as such; provided, however, that in no event shall Parent be required to expend on an annual basis more than three hundred percent (300%) of the current amount expended by the Company (the “Insurance Amount”) to maintain or procure insurance coverage; and further provided that if Parent is unable to maintain or obtain the insurance called for by this Section 7.06(b) Parent shall use all reasonable efforts to obtain as much comparable insurance as is available for the Insurance Amount; and provided, further, that notwithstanding the foregoing, the obligations under this Section 7.06(b) may be satisfied if the Surviving Corporation purchases a “tail” policy

under the Company’s existing directors’ and officers’ insurance policy that (i) has an effective term of six (6) years from the Effective Time, (ii) covers those persons who are officers and directors of the Company on the date of this Agreement, for actions and omissions occurring on or prior to the Effective Time and (iii) contains terms and conditions (including without limitation coverage amounts) that are at least as favorable in the aggregate as the terms and conditions of the Company’s directors’ and officers’ insurance policy in effect on the date hereof.

(c) Until six years from the Effective Time, unless otherwise required by applicable law, the certificate of incorporation and bylaws of the Surviving Corporation shall contain provisions no less favorable with respect to the elimination of liability of directors and the indemnification of directors and officers (including as to advancement of expenses) than are set forth in the Restated Certificate of Incorporation and Bylaws of the Company, as in effect on the date hereof.

(d) In the event the Parent, Surviving Corporation or any of their successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or Surviving Company or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Parent or the Surviving Corporation, as the case may be, assume the obligations set forth in this Section 7.06.

(e) The provisions of this Section 7.06 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives and

shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to law, contract or otherwise.

SECTION 7.07 Notification of Certain Matters. The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (a) the occurrence, or non-occurrence, of any event the occurrence or non-occurrence of which reasonably would reasonably be expected to cause any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect and (b) any failure of the Company, Parent or Purchaser, as the case may be, to comply with or satisfy any covenant or agreement required to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 7.07 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

SECTION 7.08 Further Action; Reasonable Efforts.

(a) Upon the terms and subject to the conditions hereof, each of the parties hereto shall (i) make promptly (and in any event within five (5) Business Days after execution of this Agreement) its respective filings, and thereafter make any other required submissions, under the HSR Act with respect to the Transactions and (ii) use all reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the Transactions, including, without limitation, using all reasonable efforts to obtain all Permits, consents, approvals, authorizations, qualifications and orders of Governmental Authorities and parties to contracts with the Company and the Subsidiaries as are necessary for the consummation of the Transactions and to fulfill the conditions to the Offer and the Merger. In case, at any time after the Effective Time, any further action is necessary or desirable to carry out

the purposes of this Agreement, the proper officers and directors of each party to this Agreement shall use all reasonable efforts to take all such action. Parent or the Purchaser will pay all filing fees associated with the HSR submission.

(b) Each of the parties hereto agrees to cooperate and use all reasonable efforts to vigorously contest and resist any Action, including administrative or judicial Action, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that is in effect and that restricts, prevents or prohibits consummation of the Transactions, including, without limitation, by vigorously pursuing all available avenues of administrative and judicial appeal.

SECTION 7.09 Public Announcements. Parent, Purchaser and the Company agree that no public release or announcement concerning the Transactions, the Offer or the Merger shall be issued by any party without the prior consent of the other party (which consent shall not be unreasonably withheld), except as such release or announcement may be required by Law or the rules or regulations of any United States securities exchange or Nasdaq, in which case the party required to make the release or announcement shall use its reasonable efforts to allow the other party time to comment on such release or announcement in advance of such issuance.

Each of the parties hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, and any appellate court thereof, for any litigation arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby, to the extent the Court of Chancery has jurisdiction over the claims alleged in such litigation, or, if the Court of Chancery does not have jurisdiction over the claims alleged in such litigation, the courts of the State of Delaware and of the United States of America located in the State of Delaware, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such litigation except in such courts, (ii) waives any objection to the laying of venue of any such litigation in such Delaware courts and (iii) agrees not to plead or claim in any Delaware court that such litigation brought therein has been brought in an inconvenient

(b) any Governmental Authority shall have issued an order, decree, injunction or ruling or taken any other action permanently restraining, enjoining or otherwise prohibiting or materially delaying or preventing the Transactions and such order, decree, injunction, ruling or other action shall have become final and non-appealable;

(c) there shall have been any statute, rule, regulation, legislation or interpretation enacted, promulgated, amended or issued applicable to (i) Parent, the Company or any subsidiary or affiliate of Parent or the Company or (ii) any Transaction, by any United States or Governmental Authority with appropriate jurisdiction, other than the routine application of the waiting period provisions of the HSR Act to the Offer or the Merger, that is reasonably likely to result, directly or indirectly, in any of the consequences referred to in clauses (i) through (v) of paragraph (a) above;

A-2

(d) since the date of the Merger Agreement, any Material Adverse Effect, or any occurrence, circumstance or event that is reasonably likely to result in a Material Adverse Effect, shall have occurred;

(e) there shall have occurred (i) a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States (whether or not mandatory), (ii) any limitation (whether or not mandatory) by any United States Governmental Entity on the extension of credit generally by banks or other financial institutions, or (iii) in the case of either of the foregoing existing at the time of the commencement of the Offer, a material acceleration or worsening thereof;

(f) any representation or warranty of the Company in the Agreement that is qualified as to materiality or Material Adverse Effect shall not be true and correct in any respect or any such representation or warranty that is not so qualified shall not be true and correct in any material respect, in each case as if such representation or warranty was made as of such time on or after the date of this Agreement;

(g) the Company shall have failed to perform, in any material respect, any obligation or to comply, in any material respect, with any agreement or covenant of the Company to be performed or complied with by it under the Agreement; provided Parent shall have given notice to the Company in reasonable detail of such failure to perform or comply and, if such failure is capable of cure within thirty (30) days, the Company shall not have cured any such failure capable of cure within thirty (30) days after receipt of such notice;

(h) the Board of Directors or any committee thereof shall have (i) withdrawn, or modified or changed in a manner adverse to the Transactions, to Parent or to Purchaser (including by amendment of the Schedule 14D-9), its recommendation of the Offer, this

A-3

Agreement, or the Merger, (ii) recommended any Acquisition Proposal, (iii) taken a neutral position or made no recommendation with respect to another proposal or offer (other than by Parent or Purchaser) after a reasonable amount of time (and in no event more than ten (10) Business Days following receipt thereof) has elapsed for the Board or any committee thereof to review and make a recommendation with respect thereto or (iv) resolved to do any of the foregoing;

(i) the Purchaser shall have failed to receive a certificate executed by the Company’s President or a Vice President of the Company on behalf of the Company, dated as of the scheduled expiration of the Offer, to the effect that the conditions set forth in paragraphs (f), (g), (i), and (l) of this Annex A have not occurred;

(j) the Agreement shall have been terminated in accordance with its terms;

(k) Purchaser and the Company shall have agreed in writing that Purchaser shall terminate the Offer or postpone the acceptance for payment of Shares thereunder; or

(l) the useable and saleable (and not expired or short-dated) inventories of the eighty percent (80%) Items of the Company and the Subsidiaries, taken as a whole, as determined by Parent after physical inspection thereof and valued in accordance with GAAP consistently applied with the past practices of the Company, have a realizable value (net of reserves) more than five percent (5%) less than the carrying value of the inventories of the eighty percent (80%) Items of the Company and its Subsidiaries, taken as whole, reflected on the consolidated balance sheet of the Company and its Subsidiaries dated as of the date of such physical inspection of the inventory; provided, however, that (A) Parent shall have conducted its physical inspection as promptly as practicable and in any event within five (5) Business Days after the later of (x) the date of this Agreement and (y) the date Parent shall

A-4

have been given full access to the facilities of the Company and the Subsidiaries required by Parent to conduct the physical inspection of the inventories contemplated by this clause (the “Completion Date”), (B) if Parent shall have determined that this condition has not been satisfied, Parent shall have notified the Company of such determination within five (5) Business Days after the Completion Date, which notice shall include Parent’s calculations and a detailed explanation of the basis upon which Parent contends the condition has not been satisfied and (C) if the Company shall have notified Parent within two (2) Business Days after Parent’s notice that the Company disputes (a “Dispute”) Parent’s calculations, the Firm shall not have determined (which determination shall be final and binding upon the parties), after review the positions of Parent and the Company with respect to the Dispute and the performance of appropriate testing procedures (as reasonably determined by the Firm) and in any event within thirty (30) calendar days (the “Dispute Resolution Period”) after its acceptance of its selection, that this condition has been satisfied, (it being understood that Parent and the Company will promptly provide to the Firm all information it reasonably requests to assist it to reach its determination and will instruct the Firm to endeavor to make its determination as promptly as practicable),

which, in the reasonable judgment of Parent or Purchaser, in any such case, and regardless of the circumstances (including action or inaction by Parent or Purchaser) giving rise to such condition, makes it inadvisable to proceed with the Offer and/or with such acceptance for payment of the Shares; provided, however, that Purchaser may not terminate the Offer on the basis of a condition that exists as a result of a breach by Parent or Purchaser of their respective obligations under this Agreement.

A-5

The foregoing conditions are for the sole benefit of Parent and Purchaser, may be waived by Parent or Purchaser, in whole or in part, at any time and from time to time in the sole discretion of Parent or Purchaser. The failure by Parent or Purchaser at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time-to-time.
