WHEREAS, the Board of Directors of each of Parent, Sub and the Company has determined that a business combination between Parent and the Company is fair to their respective stockholders and is in the best interests of such stockholders;

WHEREAS, the Board of Directors of each of Parent, Sub and the Company has approved a merger of Sub with and into the Company, with the Company as the surviving corporation, upon the terms and subject to the conditions set forth herein (the "Merger");

WHEREAS, concurrently with the execution of this Agreement, the Company has granted to Sub an option (the "Parent Option") to acquire shares of the Company's Common Stock, no par value (the "Company Common Stock");

WHEREAS, concurrently with the execution of this Agreement, each of the individuals identified on Exhibit B-1 hereto (the "Identified Shareholders") has duly executed and delivered to Parent a Voting Agreement pursuant to which, among other things, each of the Identified Shareholders has granted to Parent an irrevocable proxy and has agreed to vote all the shares of the Company Common Stock owned by the Identified Shareholders in favor of the Merger, on the terms set forth in Exhibit B-2 hereto (the "Shareholders Agreement"); and

WHEREAS, the Company has specifically requested that Parent and Sub enter into this Agreement.

NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE I

The Offer and Merger

SECTION 1.01 The Offer.

(a) Subject to the conditions of this Agreement, as promptly as reasonably practicable after the date of this Agreement, Sub shall, and Parent shall cause Sub to, commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations thereunder, the "Exchange Act")), an offer (the "Offer") for all the outstanding shares of common stock, no par value, of the Company (the "Company Common Stock") at a price per share of the Company Common Stock of $18.85, net to each seller in cash (the "Offer Price"). The obligations of Sub to, and of Parent to cause Sub to, accept for payment, and pay for, any shares of Company Common Stock tendered pursuant to the Offer are subject only to the satisfaction or waiver by Sub of the conditions set forth in Exhibit A. Sub expressly reserves the right to waive any condition to the Offer or modify the terms of the Offer, except that, without the consent of the Company, Sub shall not (i) reduce the number of shares of the Company Common Stock subject to the Offer, (ii) reduce the Offer Price, (iii) waive or change the Minimum Tender Condition (as defined in Exhibit A), (iv) add to the conditions set forth in Exhibit A, modify any condition set forth in Exhibit A or amend any term of the Offer set forth in this Agreement, in each case, in any manner adverse to the holders of the Company Common Stock or (v) change the form of consideration payable in the Offer (other than by adding consideration). Notwithstanding the foregoing, Sub (i) shall extend the Offer, if at the scheduled expiration date of the Offer any of the conditions set forth in Exhibit A (other than the Minimum Tender Condition or condition (d), (e) or (h)) to Sub's obligation to purchase shares of the Company Common Stock are not satisfied or waived, until such time as such conditions are satisfied or waived but in no event later than September 30, 2002, and (ii) may, without the consent of the Company, extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the "SEC") or the staff thereof applicable to the Offer. In addition, if, at the scheduled or extended expiration date of the Offer, all the conditions to the Offer

have been satisfied or waived but the Company Common Stock tendered and not withdrawn pursuant to the Offer constitutes less than 90% of the outstanding Company Common Stock, without the consent of the Company, Sub shall (subject to applicable law) have the right to provide for a "subsequent offering period" (as contemplated by Rule 14d-11 under the Exchange Act), for up to 20 business days after Sub's acceptance for payment of the shares of Company Common Stock then tendered and not withdrawn pursuant to the Offer. On the terms and subject to the conditions of the Offer and this Agreement, Sub shall, and Parent shall cause Sub to, pay for all shares of the Company Common Stock validly tendered and not withdrawn pursuant to the Offer that Sub becomes obligated to purchase pursuant to the Offer as soon as practicable after the expiration of the Offer or (in the case of shares tendered during any subsequent offering period) as soon as practicable following the valid tender thereof.

(b) On the date the Offer is commenced, Parent and Sub 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 as an exhibit or incorporate by reference the Offer to Purchase (or portions thereof) and forms of the related letter of transmittal and summary advertisement (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the "Offer Documents"). Each of Parent, Sub and the Company shall promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and to be disseminated to the Company's shareholders, in each case as and to the extent required by applicable federal securities laws. Parent and Sub shall provide the Company and its counsel with any comments Parent, Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments.

(c) Parent shall provide or cause to be provided to Sub on a timely basis the funds necessary to purchase any shares of the Company Common Stock that Sub becomes obligated to purchase pursuant to the Offer.

SECTION 1.02 Company Actions.

(a) The Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated by this Agreement (collectively, the "Transactions").

(b) Promptly after the Offer is commenced, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer, including an Information Statement (as defined in Section 3.05(b)) (such Schedule 14D-9, as amended from time to time, the "Schedule 14D-9"), and shall mail the Schedule 14D-9 (including the Information Statement) to the holders of the Company Common Stock. Each of the Company, Parent and Sub shall promptly correct any information provided by it for use in the Schedule 14D-9 (including the Information Statement) if and to the extent that such information shall have become false or misleading in any material respect, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 (including the Information Statement) and to cause the Schedule 14D-9 (including the Information Statement) as so amended or supplemented to be filed with the SEC and disseminated to the Company's shareholders, in each case as and to the extent required by applicable federal securities laws. The Company shall provide Parent and its counsel with any comments the Company or its counsel may receive after the date of this Agreement from the SEC or its staff with respect to the Schedule 14D-9 or the Information Statement promptly after the receipt of such comments.

(c) In connection with the Offer, the Company shall cause its transfer agent to furnish Sub promptly with mailing labels containing the names and addresses of the record holders of the Company Common Stock as of a recent date and of those persons becoming record holders subsequent to such

date, together with copies of all lists of shareholders, security position listings and computer files and all other information in the Company's possession or control regarding the beneficial owners of the Company Common Stock, and shall furnish to Sub such information and assistance (including updated lists of shareholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to the Company's shareholders.

SECTION 1.03 The Merger. On the terms and subject to the conditions set forth in this Agreement, and in accordance with the Michigan Business Corporation Act (the "MBCA") and the Delaware General Corporation Law (the "DGCL"), Sub shall be merged with and into the Company at the Effective Time (as defined in Section 1.05). At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation").

SECTION 1.04 Closing. The closing (the "Closing") of the Merger shall take place at the offices of O'Melveny & ▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ at 7:00 a.m. on the second business day following the satisfaction (or, to the extent permitted by applicable Law (as defined in Section 3.05), waiver by all parties) of the conditions set forth in Section 7.01, or at such other place, time and date as shall be agreed in writing between Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date".

SECTION 1.05 Effective Time. Subject to the provisions of this Agreement, on the Closing Date, the parties shall file with the Department of Consumer and Industry Services of the State of Michigan and the Secretary of State of the State of Delaware, a certificate of merger or other appropriate documents (in each such case, "Articles of Merger") executed in accordance with the relevant provisions of the MBCA and the DGCL, as the case may be, and shall make all other filings or recordings required under the MBCA and the DGCL. The Merger shall become effective at such time as the applicable Articles of Merger are duly filed with the Department of Consumer and Industry Services of the State of Michigan and the Secretary of State of the State of Delaware, or at such other time as Parent and the Company shall agree and specify in the Articles of Merger (the time the Merger becomes effective being the "Effective Time").

SECTION 1.06 Effects. The Merger shall have the effects set forth in the MBCA and the DGCL.

SECTION 1.07 Articles of Incorporation and By-laws.

(a) The Articles of Incorporation of the Company at the Effective Time shall be the Articles of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

(b) The By-laws of the Company as in effect immediately prior to the Effective Time shall be the By-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

ARTICLE II

Effect on the Capital Stock of the
Constituent Corporations; Exchange of Certificates

SECTION 2.01 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the Company Common Stock or any shares of capital stock of Sub:

(a) Capital Stock of Sub. Each issued and outstanding share of capital stock of Sub shall be converted into and become one fully paid and nonassessable share of common stock, no par value, of the Surviving Corporation.

(b) Cancellation of the Company-Owned Stock and Parent-Owned Stock. Each share of Company Common Stock that is held by the Company, Parent or Sub shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion of the Company Common Stock. Subject to Section 2.01(b), each issued and outstanding share of the Company Common Stock shall be converted into the right to receive the Offer Price in cash. The cash payable upon the conversion of shares of the Company Common Stock pursuant to this Section 2.01(c) is referred to collectively as the "Merger Consideration". As of the Effective Time, all such shares of the Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of the Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration upon surrender of such certificate in accordance with Section 2.02, without interest.

SECTION 2.02 Exchange of Certificates.

(a) Paying Agent. Parent shall promptly appoint a financial or other institution reasonably acceptable to the Company to act as paying agent (the "Paying Agent") for the payment of the Merger Consideration upon surrender of certificates representing the Company Common Stock. Parent shall take all steps necessary to enable and cause the Surviving Corporation to provide to the Paying Agent on a timely basis, as and when needed after the Effective Time, cash necessary to pay for the shares of the Company Common Stock converted into the right to receive cash pursuant to Section 2.01(c) (such cash being hereinafter referred to as the "Exchange Fund").

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent shall instruct the Paying Agent to mail to each holder of record of a certificate or certificates (the "Certificates") that immediately prior to the Effective Time represented outstanding shares of the Company Common Stock, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of the Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the

payment to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender Merger Consideration as contemplated by this Section 2.02.

(c) No Further Ownership Rights in the Company Common Stock. The Merger Consideration paid in accordance with the terms of this Article II upon conversion of any shares of the Company Common Stock shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of the Company Common Stock, and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of the Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any certificates formerly representing shares of the Company Common Stock are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Company Common Stock twelve months after the Effective Time shall be delivered to Parent, upon demand, and any holder of the Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to Parent for payment of its claim for Merger Consideration.

(e) No Liability. None of Parent, Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Investment of Exchange Fund. The Paying Agent shall invest the Exchange Fund, as directed by Parent, on a daily basis; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by ▇▇▇▇▇'▇ Investors Service, Inc. or Standard & Poor's Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker's acceptances of commercial banks with capital exceeding $500 million. Any interest and other income resulting from such investments shall be paid to Parent.

(g) Withholding Rights. Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of the Company Common Stock pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Code (as defined in Section 3.09), or under any provision of state, local or foreign tax Law. To the extent that amounts are so withheld by Parent or the Surviving Corporation and paid over to the appropriate taxing authority, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the Company Common Stock in respect of which such deduction and withholding was paid by Parent or the Surviving Corporation.

SECTION 2.03 Stock Options.

(a) At the Effective Time, each outstanding option or warrant to purchase shares of the Company Common Stock (a "Stock Option" or, collectively, the "Stock Options") issued pursuant to (i) the Company's 1996 Stock Incentive Plan for Key Employees or Non-Employee Director Stock Option Plan (the "Option Plans"); or (ii) any other plan or instrument, whether vested or unvested, shall be cancelled in exchange for a single lump sum cash payment (less any applicable income or employment tax withholding) payable by Parent at the Effective Time equal to the Cash-Out Price (as defined below). The "Cash-Out Price" will be paid only if the exercise price per share of the Company Common Stock of the Stock Option is less than the Merger Consideration and will be equal to the product of (i) the number of shares of the Company Common Stock subject to any Stock Option vested immediately prior to the Effective Time (including any Stock Option which becomes vested on

or prior to the Effective Time in accordance with the terms of an automatic acceleration provision in existence as of the date hereof and disclosed to Parent hereunder), multiplied by (ii) the excess of the Merger Consideration over the exercise price per share of the Company Common Stock of such Stock Option.

(b) Prior to the Effective Time, the Company shall use its commercially reasonable efforts to take all actions (including, if appropriate, amending the terms of the Option Plans or the Stock Options) and obtain such consents as are necessary to give effect to the transactions contemplated by Section 2.03(a).

ARTICLE III

Representations and Warranties of the Company

The Company represents and warrants to Parent and Sub as follows:

SECTION 3.01 Organization, Standing and Power. Each of the Company and each of its subsidiaries (the "Company Subsidiaries") is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it is organized and has full corporate power and authority and possesses all governmental franchises, licenses, permits, authorizations and approvals necessary to enable it to own, lease or otherwise hold its properties and assets and to conduct its businesses as presently conducted, except for failures which, individually or in the aggregate, have not had and would not reasonably be expected to have a Company Material Adverse Effect. The Company and each Company Subsidiary is duly qualified or licensed to do business in each jurisdiction where the nature of its business or its ownership or leasing of its properties make such qualification or licensing necessary, except where the failure to so qualify or be licensed has not had and would not reasonably be expected to have a Company Material Adverse Effect. The Company has made available to Parent true and complete copies of the articles of incorporation of the Company, as amended to the date of this Agreement (as so amended, the "Company Charter"), and the By-laws of the Company, as amended to the date of this Agreement (as so amended, the "Company By-laws"), and the comparable charter and organizational documents of each Company Subsidiary, in each case as amended through the date of this Agreement. As used in this Agreement, the phrase "Company Material Adverse Effect" means a material adverse effect on (i) the business, results of operations or condition (financial or otherwise) of the Company and Company Subsidiaries, considered as a whole, or (ii) the ability of the Company to consummate the Transactions or to perform its material obligations under this Agreement; provided, however, that none of the following shall constitute a Company Material Adverse Effect: (a) changes, events or occurrences arising from or relating to the United States securities markets which are not specific to the Company; (b) any adverse changes, events, developments or effects arising from or relating to general business, political or economic conditions, or business conditions in the industries in which the Company and the Company Subsidiaries operate, in each case which are not specific to the Company or any Company Subsidiary; (c) any failure of the Company and Company Subsidiaries, considered as a whole, to meet internal forecasts provided by the Company to Parent on or prior to the date of this Agreement; (d) any adverse changes, events, developments or effects arising out of the announcement of this Agreement or the Company's actions in connection with this Agreement; (e) any changes in any tax laws and regulations or accounting rules; and (f) any adverse changes, events, developments or effects arising from or relating to the matters specifically set forth in Schedule 3.01 hereto.

SECTION 3.02 Company Subsidiaries; Equity Interests.

(a) The letter, dated as of the date of this Agreement, from the Company to Parent and Sub (the "Company Disclosure Letter") lists each Company Subsidiary and its jurisdiction of organization. All the outstanding shares of capital stock of each Company Subsidiary have been validly issued and are fully paid and nonassessable and, except as set forth in the Company Disclosure Letter, are owned by

the Company, by another Company Subsidiary or by the Company and another Company Subsidiary, free and clear of all pledges, liens, charges, mortgages, encumbrances and security interests of any kind or nature whatsoever (collectively, "Liens"), except for such Liens as have not had and would not reasonably be expected to have a Company Material Adverse Effect.

(b) Except for its interests in the Company Subsidiaries and except for the ownership interests set forth in the Company Disclosure Letter, the Company does not own, directly or indirectly, any capital stock, membership interest, partnership interest, joint venture interest or other equity interest in any person other than any such capital stock or other interests with a current book value, in the aggregate, not in excess of $500,000.

SECTION 3.03 Capital Structure. The authorized capital stock of the Company consists of 15,000,000 shares of the Company Common Stock and 1,000,000 shares of preferred stock, no par value ("Company Preferred Stock" and, together with the Company Common Stock, the "Company Capital Stock"). No shares of the Company Preferred Stock are issued and outstanding or reserved for issuance. At the close of business on March 7, 2002, (i) 6,196,362 shares of the Company Common Stock were issued and outstanding, (ii) 915,978 shares of the Company Common Stock were subject to outstanding Stock Options, (iii) 209,629 additional shares of the Company Common Stock were available for issuance pursuant to the Option Plans, and (iv) 77,935 shares of the Company Common Stock were available for issuance under the Company's Employee Stock Purchase Plan. Except as set forth in the Company Disclosure Letter, between March 7, 2002 and the date of this Agreement, the Company has not issued any shares of the Company Capital Stock (other than shares of the Company Common Stock issued upon exercise of Stock Options) or granted or agreed to grant any options to purchase the Company Common Stock. All outstanding shares of the Company Capital Stock are, and all such shares that may be issued prior to the Effective Time will be when issued, duly authorized, validly issued, fully paid and nonassessable and not subject to or issued in violation of any purchase option, call option, right of first refusal, preemptive right, subscription right or any similar right to which the Company is a party or otherwise bound. There are not any bonds, debentures, notes or other indebtedness of the Company having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which holders of the Company Common Stock may vote ("Voting Company Debt"). Except as set forth above or in the Company Disclosure Letter, as of the date of this Agreement, there are not any options, warrants, rights, convertible or exchangeable securities, "phantom" stock, "phantom" stock rights, stock appreciation rights, stock-based performance units, commitments, Contracts (as defined in Section 3.05(a)), arrangements or undertakings of any kind to which the Company or any Company Subsidiary is a party or by which any of them is bound (i) obligating the Company or any Company Subsidiary to issue, deliver or sell, or cause to be issued, delivered or sold, additional shares of capital stock or other equity interests in, or any security convertible or exercisable for or exchangeable into any capital stock of or other equity interest in, the Company or of any Company Subsidiary or any Voting Company Debt (or to make any payment based on the value of any equity interest in the Company or in any Company Subsidiary) or (ii) obligating the Company or any Company Subsidiary to issue, grant, extend or enter into any such option, warrant, call, right, security, commitment, Contract, arrangement or undertaking. As of the date of this Agreement, there are not any outstanding contractual obligations of the Company or any Company Subsidiary to repurchase, redeem or otherwise acquire any shares of capital stock of the Company or any Company Subsidiary.

SECTION 3.04 Authority; Execution and Delivery; Enforceability.

(a) The Company has all requisite corporate power and authority to execute and deliver this Agreement and to consummate the Transactions. The execution and delivery by the Company of this Agreement and the consummation by the Company of the Transactions have been duly authorized by all necessary corporate action on the part of the Company, subject, in the case of the Merger, to receipt of the Company Shareholder Approval (as defined in Section 3.04(c)). The Company has duly

executed and delivered this Agreement, and, assuming the due authorization, execution and delivery hereof by Parent and Sub, this Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing.

(b) The Company's Board of Directors (the "Company Board"), at a meeting duly called and held duly and unanimously adopted resolutions (i) approving this Agreement, the Offer, the Merger and the other Transactions, (ii) determining that the terms of the Offer, the Merger and the other Transactions are fair to and in the best interests of the Company and its shareholders, (iii) recommending that the holders of the Company Common Stock accept the Offer and tender their shares of the Company Common Stock pursuant to the Offer (the "Company Recommendation"), (iv) recommending that the Company's shareholders approve this Agreement, if such approval is required, (v) adopting a plan of merger relating to the Merger as required by the MBCA and (vi) directing that such plan of merger be submitted for approval by the Company's shareholders, if necessary. In addition, the Company Board has taken all action necessary to render Chapter 7A and Chapter 7B of the MBCA and Article 10 of the Company's By-laws inapplicable to this Agreement, the Offer, the Merger, the other Transactions and Sub's holding and voting of shares of the Company Common Stock held by Sub after the Offer or acquired upon exercise of the Parent Option. To the Company's knowledge, no other state takeover statute or similar statute or regulation applies or purports to apply to the Company with respect to this Agreement, the Offer, the Merger or any other Transaction. Unless otherwise required by its fiduciary duties (as determined in good faith by a majority of its members after consultation with outside legal counsel to the Company) the Company Board shall not amend, modify, withdraw, condition or qualify the Company Recommendation in a manner adverse to Parent or Sub.

The Employee Plans entered into, maintained or contributed to, by any Company Subsidiary for the benefit of any current or former employees, officers or directors of, or independent contract with respect to, any Company Subsidiary (or under which any Company Subsidiary has any current potential liabilities or obligations) are not, individually or in the aggregate, material to the Company and the Company Subsidiaries considered as a whole (collectively, the "Company Subsidiaries' Employee Plans" and together with the Company Pension Plans and the Company Employee Plans, the "Company Benefit Plans").

SECTION 5.03 Actions of Company Board. Neither the Company Board nor any committee thereof shall (i) take any action that would result in the holders of the Company Capital Stock no longer being legally capable under the MBCA of validly approving the Merger or this Agreement or (ii) adopt any amendment to the Company Charter or the Company By-Laws or any resolution or take any other action that would have the effect of rescinding the actions taken to render Chapter 7A and Chapter 7B of the MBCA or Article 10 of the Company's By-laws inapplicable to the Offer, the Merger and the other Transactions.

SECTION 6.04 Indemnification.

(a) Parent shall, and shall cause the Surviving Corporation to, honor, to the fullest extent permitted by applicable Law, all the Company's obligations to indemnify, defend and hold harmless (including any obligations to advance funds for expenses) the present or former directors or officers of the Company and the Company Subsidiaries and to advance expenses to them for acts or omissions by such directors and officers occurring at or prior to the Effective Time to the extent that such obligations of the Company exist on the date of this Agreement, whether pursuant to the Company Charter, the Company By-laws, individual indemnity agreements or otherwise, and such obligations shall survive the Merger and shall continue in full force and effect in accordance with the terms of the Company Charter, the Company By-laws and such individual indemnity agreements from the Effective Time.

(b) The Articles of Incorporation and by-laws of the Surviving Corporation shall contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of former or present directors, officers and employees than are presently set forth in the Company Charter and the Company By-laws, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of any such individuals.

(c) For a period of six years after the Effective Time, Parent shall cause to be maintained in effect, at no expense to the beneficiaries, the current policies of directors' and officers' liability insurance maintained by the Company (provided that Parent may substitute therefor policies with reputable and financially sound carriers of at least the same coverage and amounts containing terms and conditions which are no less advantageous) with respect to claims arising from or related to facts or events which occurred at or before the Effective Time; provided, however, that Parent shall not be obligated to make annual payments for such insurance to the extent such payments exceed 200% of the annual cost as of the date hereof by the Company for such insurance (such 200% amount, the "Maximum Cost"). If such insurance coverage cannot be obtained at all, or can only be obtained at an annual cost in excess of the Maximum Cost, Parent shall maintain the most advantageous policies of directors' and officers' insurance obtainable for an annual cost equal to the Maximum Cost; provided, however, if such insurance coverage cannot be obtained at all, Parent shall purchase all available extended reporting periods with respect to pre-existing insurance in an amount which, together with all other insurance purchased pursuant to this Section 6.06(c), does not exceed the Maximum Cost.

Parent and Sub, on the one hand, and the Company, on the other hand, shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the Offer, the Merger and the other Transactions and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange.

SECTION 6.06 Directors. Promptly upon the acceptance for payment of, and payment by Sub for, the shares of the Company Common Stock validly tendered pursuant to the Offer, Sub shall be entitled to designate such number of directors on the Company Board as will give Sub, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board equal to at least that number of directors, rounded up to the next whole number, which is the product of (a) the total number of directors on the Company Board (giving effect to the directors elected pursuant to this sentence) multiplied by (b) the percentage that (i) such number of shares of the Company Common Stock so accepted for payment and paid for by Sub plus the number of shares of the Company Common Stock otherwise owned by Parent, Sub or any other subsidiary of Parent bears to (ii) the number of such shares outstanding, and the Company shall, at such time, cause Sub's designees to be so elected; provided, however, that in the event that Sub's designees are appointed or elected to the Company Board, until the Effective Time the Company Board shall have at least three directors who are Directors on the date of this Agreement and who are not officers of the Company (the "Independent Directors"); and provided further that, in such event, if the number of Independent Directors shall be reduced below three for any reason whatsoever, any remaining Independent Directors (or Independent Director, if there shall be only one remaining) shall be entitled to designate

persons to fill such vacancies who shall be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Directors then remain, the other directors shall designate three persons to fill such vacancies who are not officers, shareholders or affiliates of the Company, Parent or Sub, and such persons shall be deemed to be Independent Directors for purposes of this Agreement. Subject to applicable Law, the Company shall take all action reasonably requested by Parent within the Company's powers and necessary to effect any such election, including mailing to its shareholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder and the Company shall make such mailing with the mailing of the Schedule 14D-9 Amendment (provided that Sub shall have provided to the Company on a timely basis all information required to be included in the Information Statement with respect to Sub's designees). In connection with the foregoing, the Company shall promptly, at the option of Sub, either increase the size of the Company Board or obtain the resignation of such number of its current directors as is necessary to enable Sub's designees to be elected or appointed to the Company Board as provided above.

SECTION 6.07 Employee Matters. (a) Employees of the Surviving Corporation shall be entitled to compensation and incentive arrangements similar to compensation and incentive arrangements offered by Parent to its similarly situated employees and Parent will set aside a pool of 300,000 stock options under Parent's stock option plan for grants of stock options to employees of Surviving Corporation, which stock options will be granted in the sole and absolute discretion of Parent. With respect to any employee of the Surviving Corporation that is terminated without cause, Surviving Corporation shall provide severance pay comparable to that made available to similarly situated employees of Parent terminated without cause.

(b) To the extent permitted under applicable Law and the applicable employee benefit plans, Parent shall, or shall cause the Surviving Corporation to, give employees of the Company and Company Subsidiaries at the Effective Time ("Affected Employees") full credit for purposes of eligibility under such employee benefit plans or arrangements maintained by the Parent or the Surviving Corporation in which such Affected Employees participate for such Affected Employees' service with the Company or any Company Subsidiary to the same extent as if the Affected Employees had been employees of Parent during such Affected Employees' service with the Company or any Company Subsidiary.

(c) To the extent permitted under applicable Law and the applicable welfare benefit plans, Parent shall, or shall cause the Surviving Corporation to, (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to any participation and coverage requirements applicable to the Affected Employees under any welfare benefit plans in which such Affected Employees may be eligible to participate after the Effective Time, other than limitations or waiting periods that are already in effect with respect to such Affected Employees and that have not been satisfied as of the Effective Time under any welfare benefit plan maintained for the Affected Employees immediately prior to the Effective Time, and (ii) provide each Affected Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements under any welfare benefit plans that such Affected Employees are eligible to participate in after the Effective Time.

SECTION 6.08 Return of Evaluation Materials. Immediately after the execution and delivery of this Agreement, the Company shall request the return of all confidential information and reports, analyses, compilations, data, studies and other material that contain or otherwise reflect or are generated from such confidential information provided to any third party under any confidentiality or similar agreement, and shall use its reasonable efforts to enforce any "standstill" or similar obligations under all such confidentiality or similar agreements, in each case except the Confidentiality Agreement.

(b) by either Parent or the Company, duly authorized by the Board of Directors of such party:

(i) unless the Company Common Stock has been purchased pursuant to the Offer, if the Merger is not consummated on or before September 30, 2002 (the "Outside Date"), unless the failure to consummate the Merger is the result of a material breach of this Agreement by the party seeking to terminate this Agreement;

(d) by Parent, duly authorized by its Board of Directors, if the Company Board or any committee thereof withdraws the Company Recommendation or its approval or recommendation of this Agreement or the Merger (it being understood and agreed that a communication by the Company Board to the shareholders of the Company pursuant to Rule 14d-9(f)(3) under the Exchange Act (or any similar communication to the shareholders of the Company in connection with the commencement of a tender offer or exchange offer) shall not be deemed to constitute a withdrawal of the Company Recommendation or its recommendation of this Agreement or the Merger) or approves or recommends any Business Combination with a person other than Parent and Sub;

(e) by the Company, duly authorized by its Board of Directors, prior to the acceptance of shares of the Company Common Stock for payment pursuant to the Offer, if Parent breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform cannot be or has not been cured within 30 days after the giving of written notice to Parent of such breach (provided that the Company is not then in material breach of any representation, warranty or covenant in this Agreement);

(f) by the Company, duly authorized by its Board of Directors, if the Company has entered into or publicly announced its intention to enter into an agreement or an agreement in principle with respect to a Superior Proposal, in strict compliance with Section 5.02 hereof; provided, however, that the right to terminate this Agreement pursuant to this Section 8.01(f) shall not be available if (1) the Company has breached any obligation under Section 5.02 hereof, or (2) the Company fails to pay the fee that it is required to pay pursuant to Section 8.03; or

(g) by Parent, duly authorized by its Board of Directors, if the Company has entered into or publicly announced its intention to enter into an agreement or an agreement in principle with respect to a Business Combination with a third party other than Parent or Sub, or any person, other than Parent or Sub or any of their affiliates, including a group (as defined under the Exchange Act), becomes the beneficial owner (as defined in Rule 13d-3 promulgated under the Exchange Act) of 50% or more or the voting power of the Company or the outstanding Company Capital Stock.

SECTION 8.02 Effect of Termination. In the event of termination of this Agreement by either the Company or Parent as provided in Section 8.01, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of Parent, Sub or the Company, other than Section 3.14, Section 4.06, Section 4.07, Section 5.03, the last sentence of Section 6.02, this Section 8.02, Section 8.03 and Article IX, which provisions shall survive such termination, and except to the extent that such termination results from the willful breach by a party of any representation, warranty or covenant set forth in this Agreement.

SECTION 8.03 Fees and Expenses.

(a) In the event that this Agreement is terminated pursuant to:

(i) Sections 8.01(d), (f) or (g);

(ii) Section 8.01(c) and within twelve months thereafter the Company enters into an agreement with respect to a Business Combination constituting a Superior Proposal (which Business Combination subsequently occurs) or a Business Combination constituting a Superior Proposal occurs involving any party (or any affiliate thereof) (A) with whom the Company (or its agents) had negotiations with a view to a Business Combination constituting a Superior Proposal, (B) to whom the Company (or its agents) furnished information with a view to a Business Combination constituting a Superior Proposal or (C) who had submitted a proposal for a Superior Proposal, in the case of each of clauses (A), (B) and (C), after the date hereof and prior to such termination; or

(iii) Section 8.01(b)(i) at a time when (A) the Minimum Tender Condition is not satisfied; (B) there shall be outstanding a publicly announced offer by a third party to complete a Business Combination constituting a Superior Proposal; and (C) no other condition to the Offer is unsatisfied, and within twelve (12) months thereafter the Company enters into an agreement with respect to a Business Combination constituting a Superior Proposal (which Business Combination subsequently occurs) or a Business Combination constituting a Superior Proposal occurs, in either case involving the third party referred to above;

then Parent and Sub would suffer direct and substantial damages, which damages cannot be determined with reasonable certainty. To compensate Parent and Sub for such damages, in addition to the Parent Option, the Company shall pay to Parent the amount of $3,000,000 as liquidated damages within five business days (or such lesser time as may be specified herein) following (x) such termination referred to in Section 8.03(a)(i) or (y) the occurrence of the Business Combination which triggers the obligation to make the payment pursuant to Section 8.03(a)(ii) or (iii). Each of the parties hereto acknowledges that the amount to be paid pursuant to this Section 8.03(a), together with the Parent Option, represents liquidated damages and not a penalty and is the sole and exclusive remedy of Parent and Sub with respect to the termination of this Agreement for the reasons set forth in this Section 8.03.

(b) Except as specifically provided in this Section 8.03, each party shall bear its own expenses in connection with this Agreement and the transactions contemplated hereby.

SECTION 8.04 Amendment. Subject to applicable Law, this Agreement may be amended by the parties hereto by execution of an instrument in writing signed by all parties; provided, however, that after receipt of the Company Shareholder Approval, there shall be made no amendment that by law requires further approval by the shareholders of the Company without the further approval of such shareholders.

At any time prior to the Effective Time, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or in any document delivered pursuant to this Agreement or (c) subject to the proviso of Section 8.04, waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

SECTION 8.06 Procedure for Termination, Amendment, Extension or Waiver. A termination of this Agreement pursuant to Section 8.01, an amendment of this Agreement pursuant to Section 8.04 or an extension or waiver pursuant to Section 8.05 shall, in order to be effective, require in the case of Parent, Sub or the Company, action by its Board of Directors or the duly authorized designee of its Board of Directors; provided, however, that, notwithstanding anything to the contrary in this Agreement, after the appointment of Sub's designees to the Company Board pursuant to Section 6.06, the approval of a majority of the Independent Directors shall be required for the Company to (i) terminate this Agreement, (ii) exercise or waive any right of the Company under this Agreement, (iii) amend this Agreement or the Company Charter or the Company By-laws in any manner adverse to the holders of the Company Common Stock, (iv) extend the time for performance of any obligation of Parent or Sub under this Agreement, (v) extend or alter the Effective Time or (vi) grant any consent or take any other action with respect to this Agreement other than compliance herewith.

EXHIBIT A

Conditions of the Offer

Notwithstanding any other term of the Offer or this Agreement, Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-l(c) under the Exchange Act (relating to Sub's obligation to pay for or return tendered shares of the Company Common Stock promptly after the termination or withdrawal of the Offer), to pay for any shares of the Company Common Stock tendered pursuant to the Offer unless there shall have been validly tendered and not withdrawn prior to the expiration of the Offer that number of shares of the Company Common Stock which would represent at least a majority of the Fully Diluted Shares (the "Minimum Tender Condition"). The term "Fully Diluted Shares" means all outstanding securities entitled generally to vote in the election of directors of the Company on a fully diluted basis, after giving effect to the exercise or conversion of all options, rights and securities exercisable or convertible into such voting securities. Furthermore, notwithstanding any other term of the Offer or this Agreement, Sub shall not be required to accept for payment or, subject as aforesaid, to pay for any shares of the Company Common Stock not theretofore accepted for payment or paid for, and may terminate or amend the Offer, with the consent of the Company or if, at the time of the acceptance of such shares for payment or the payment therefor, any of the following conditions exists:

(a) there shall be pending any suit, action or proceeding by any Governmental Entity that has a reasonable likelihood of success, (i) challenging the acquisition by Parent or Sub of any Company Common Stock, seeking to restrain or prohibit the making or consummation of the Offer or the Merger or any other Transaction, or seeking to obtain from the Company, Parent or Sub any damages that are material in relation to the Company and the Company Subsidiaries taken as whole, (ii) seeking to prohibit or limit the ownership or operation by the Company, Parent or any of their respective subsidiaries of any material portion of the business or assets of the Company and the Company Subsidiaries taken as a whole or Parent and its subsidiaries taken as a whole, or to compel the Company, Parent or any of their respective subsidiaries to dispose of or hold separate any material portion of the business or assets of the Company and the Company Subsidiaries taken as a whole or Parent and its subsidiaries taken as a whole as a result of the Offer, the Merger or any other Transaction, (iii) seeking to impose limitations on the ability of Parent or Sub to acquire or hold, or exercise full rights of ownership of, any shares of the Company Common Stock, including the right to vote the Company Common Stock purchased by it on all matters properly presented to the shareholders of the Company or (iv) seeking to prohibit Parent or any of its subsidiaries from effectively controlling in any material respect the business or operations of the Company and the Company Subsidiaries;

(b) the applicable waiting period under the HSR Act has not expired or been terminated;

(c) any statute, rule, regulation, legislation, interpretation, judgment, order or injunction shall be enacted, entered, enforced, promulgated, amended or issued with respect to, or deemed applicable to, or any consent or approval withheld with respect to, (i) Parent, the Company or any of their respective subsidiaries or (ii) the Offer, the Merger or any other Transaction, in each case by any Governmental Entity that is reasonably likely to result, directly or indirectly, in any of the consequences referred to in paragraph (a) above;

(d) except as disclosed in the Filed Company SEC Documents or the Company Disclosure Letter, since the date of the most recent financial statements included in the Filed Company SEC Documents, there shall have occurred any event, change, effect or development that, individually or in the aggregate, has had or is reasonably likely to have, a Company Material Adverse Effect other than any event, change, effect or development to the extent resulting from or relating to the announcement of this Agreement and/or compliance by the Company with the covenants set forth herein;

A-1

(e) the Company Board of Directors or any committee thereof shall have withdrawn the Company Recommendation or its approval or recommendation of this Agreement or the Merger or approved or recommended any Business Combination with any person other than Parent and Sub;

(f) any of the representations and warranties of the Company in this Agreement (without regard to any materiality qualifications contained therein) shall not be true and correct as of such time (or, to the extent such representations and warranties expressly relates to an earlier date, on and as of such earlier date) and such untruth or incorrectness has had or would reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect;

(g) the Company shall have failed to perform any obligation or to comply with any agreement or covenant of the Company to be performed or complied with by it under this Agreement and such failure has had or would reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect;

(h) this Agreement shall have been terminated in accordance with its terms; or

(i) any of the Shareholders Agreements shall not remain in full force and effect;

which, in the good faith judgment of Sub or Parent, in any such case, and regardless of the circumstances giving rise to any such condition (including any action or inaction by Parent or any of its affiliates), makes it inadvisable to proceed with such acceptance for payment or payment.

The foregoing conditions are for the sole benefit of Sub and Parent and may be asserted by Sub or Parent regardless of the circumstances giving rise to such condition or may (subject to Section 1.01) be waived by Sub and Parent in whole or in part at any time and from time to time in their sole discretion. The failure by Parent, Sub or any other affiliate of Parent at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, the waiver of any such right with respect to particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
