ARTICLE 2 EFFECT OF THE MERGER ON THE CAPITAL STOCK OF COMPANY; EXCHANGE OF CERTIFICATES 2.1 Effect of Merger on Capital Stock. At the Effective Time, by virtue of the Merger, and without any party's action: (a) Capital Stock of Company. As set forth on Exhibit 4.2 hereof (which Exhibit is incorporated herein by reference and made a part hereof) and in accordance with the terms hereof, each Stockholder's shares of capital stock of the Company shall be converted into (i) common stock of Parent together with a right to purchase a fractional share of Parent's Series C Preferred Stock pursuant to the Rights Agreement (each share of stock and related right a "Parent Share" and collectively, the "Parent Shares") and/or (ii) cash. Each share of Company Common Stock, Series A Preferred Stock, and Series B Preferred Stock issued and outstanding immediately before the Effective Time and held by an Accredited Investor Stockholder will be automatically converted into the right to receive 0.35683706 of a Parent Share (the "Conversion Ratio"); and (B) $11.009399445 in cash for each such share of Company Common Stock, Series A Preferred Stock, and Series B Preferred Stock. Each share of Company Common Stock issued and outstanding immediately before the Effective Time and held by a Stockholder who is not an Accredited Investor will be automatically converted into the right to receive an amount in cash of $15.10622339 for each share of Company Common Stock. The aggregate number of Parent Shares and the aggregate amount of cash to be issued to the Stockholders in the Merger are referred to as the "Merger Consideration." Schedule 4.2 lists each Stockholder's ownership of -3- Company Common and Preferred Stock, and the respective Merger Consideration for each Stockholder. All shares of Company Common Stock, Series A Preferred Stock, and Series B Preferred Stock (each a "Converted Security" and collectively, the "Converted Securities"), when converted as provided in this Agreement, will no longer be outstanding and will automatically be canceled and retired and will cease to exist, and each holder of a certificate representing any Converted Securities immediately before the Effective Time (each a "Company Certificate" and collectively the "Company Certificates") will cease to have any rights with respect thereto, except the right to receive the applicable Merger Consideration, to be paid in consideration therefor upon surrender of that Company Certificate in accordance with Section 2.2, without interest. (b) Equity Interests in Merger Sub. All of the issued and outstanding stock of Merger Sub will cease to have any rights with respect thereto. (c) Treasury Shares. All shares of capital stock that are owned by the Company as treasury stock will be cancelled and returned and will cease to exist and no consideration will be delivered in exchange therefor. 2.2 Exchange of Company Certificates; Escrow. (a) Notwithstanding any provision of this Agreement to the contrary, each Stockholder agrees that at the Closing, $3,673,654 in cash and 118,002 Parent Shares of the Merger Consideration to be received by the Stockholders, in the aggregate, will, in lieu of being issued and/or paid to the Stockholders, be deposited in an escrow account (in the aggregate, the "Escrow Fund"), pursuant to an escrow agreement to be entered into in substantially the form attached as Exhibit 2.2 to this Agreement (the "Escrow Agreement") among Acquiror, the Stockholders, and the escrow agent named therein (the "Escrow Agent"). (b) No fractional Parent Shares will be issued to any holder of Converted Securities in the Merger. To the extent the application of the applicable Conversion Ratio to all Converted Securities held by a Stockholder receiving Parent Shares as Merger Consideration would result in a fractional number of Parent Shares being issued to that Stockholder in the Merger, the number of Parent Shares issuable to that Stockholder in respect of all those shares in the Merger will be rounded up to the next whole number of Parent Shares. (c) At the Closing, each Stockholder will surrender to Acquiror the Company Certificates owned by that Stockholder, duly endorsed in blank or accompanied by duly executed stock powers, in exchange for the applicable Merger Consideration (subject to the escrow provisions of subparagraph (a) above). As of and after the Effective Time, no holder of any Company Certificate that immediately before the Effective Time represented shares of Converted Securities will have any rights as a holder of Converted Securities other than to receive the portion of the applicable Merger Consideration issuable to that holder in the Merger. 2.3 No Further Ownership Rights, Closing of Transfer Records. The Merger Consideration paid upon the surrender of and in exchange for Converted Securities in accordance with the terms of this Agreement will be payable in full satisfaction of all rights pertaining to -4- those Converted Securities, and after the Effective Time there will be no further registration of transfers on the transfer books of Company of the Converted Securities that were outstanding immediately before the Effective Time. 2.4 Additional Agreements; Best Efforts.

(a) Whenever any claim for indemnification arises under this Article 6 (a "Claim"), the Indemnified Person will describe that claim in a written notice ("Notice of Claim") to either the Stockholders, ABV, or Acquiror depending upon the specific claim for indemnification as identified in Section 6.1(a), 6.1(b), or 6.2 (the "Indemnifying Party") and, when known, specify the facts constituting the basis for that claim and the amount or an estimate of the amount of that claim. Each Notice of Claim will (i) contain a description of the claim, (ii) specify the amount of that claim, and (iii) state that that Notice of Claim is valid under the terms of Article 6 of this Agreement. (b) If the Claim described in a Notice of Claim is, or is expected to be, made by a third party (a "Third-Party Claim"), the Indemnifying Party will undertake the defense of that Third-Party Claim by counsel reasonably satisfactory to Acquiror and the Indemnifying Party. The Indemnifying Party, without Acquiror's written consent, will not settle or compromise any Third-Party Claim or consent to entry of any judgment that does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to Acquiror and/or Acquiror's Subsidiary or Subsidiaries, or Affiliate or Affiliates, as the case may be, an unconditional release from all liability in respect of that Third-Party Claim. Acquiror will have the right at its own expense to participate in any defense of a Third-Party Claim with advisory counsel of its own choosing. In the event the Indemnifying Party, within ten days after notice of any Third-Party Claim, fails to agree in writing to defend, and does not begin defending the Third-Party Claim to the Indemnified Person's reasonable satisfaction, the Indemnified Person or Acquiror will have the right to undertake the defense, compromise, or settlement of that Third-Party Claim on behalf of, and for the account of, the Indemnified Person, at the expense and risk of the Indemnifying Party. Notwithstanding any provision in this Agreement to the contrary, failure of Acquiror to give any notice of any Third-Party Claim required by this Article 6 will not constitute a waiver of the Indemnified Person's or Acquiror's right to indemnification or a defense to any claim by Acquiror hereunder except to the extent the Indemnifying Party demonstrates that the defense of that claim is materially prejudiced by that failure. 6.4 Manner of Indemnification. All Claims against a Stockholder for indemnification pursuant to this Agreement shall be satisfied by commencing the procedures set forth in Section 7.13 within 5 days after the expiration of 180 days from the Effective Time (the "Indemnification Settlement Date"). Any Claim Notice delivered on or prior to such 180-day period shall be deemed to be the notice required by the second sentence of Section 7.13(a). An Indemnified Person (or Acquiror on that Indemnified Person's behalf) will first seek indemnity under this Agreement by following the procedures stated in Section 7.13 and the Escrow Agreement with respect to Claims based on Section 6.1(a) with any and all distributions to an Indemnified Person from the Escrow Fund to be drawn according to the Escrow Agreement. With respect to Claims pursuant to Section 6.1(b) asserted by an Indemnified Person (or Acquiror on that Indemnified Person's behalf), the Indemnified Person will first seek indemnity under this Agreement by following the procedures stated in Section 7.13. The Indemnifying Person shall satisfy any -35- amounts owed pursuant to a request for indemnity based on the preceding sentence, subject to the applicable limitations in Articles 6 and 7 hereof, by wire transfer, payment of cash, or delivery of a certified or cashier's check to Acquiror. If Acquiror becomes liable to pay any amount under this Agreement pursuant to Section 6.2, Acquiror has the right (but not the obligation) to set off that amount against any amounts that it may be entitled to under this Article 6, otherwise such amounts shall be payable by wire transfer, payment of cash, or delivery of a certified or cashier's check to the Indemnified Person. The indemnification rights provided by Article 6 of this Agreement shall be the sole and exclusive remedy to the Indemnified Persons for breaches of this Agreement and for other matters pertaining to this Agreement and the transactions contemplated hereby. 6.5 Limitations to Indemnification. (a) The Stockholders will not have any liability with respect to an Indemnified Person's Claim under Section 6.1(a) unless: (i) the Claim Notice made with respect to such Claim is made on or before 180 days after the Effective Time, and (ii) except for a Claim relating to the representations and warranties contained in Sections 4.2 or 4.5, the aggregate dollar amount of all Indemnified Persons' Claims exceeds $100,000, in which case the Stockholders will indemnify the Indemnified Persons only for the amount of those Claims that exceed $100,000. (iii) Notwithstanding anything to the contrary in this Agreement, no Stockholder will have any liability, to an Indemnified Person or otherwise, with respect to a Claim (A) regarding any Claim with respect to which a Claim Notice is not made on or before the 180th day following the Effective Time or (B) in excess of that Stockholder's Escrow Fund Contribution (except in the case of fraud or intentional misrepresentation by such Stockholder). 6.6 Net of Insurance and Tax Recoveries. The amount of any Loss required to be paid pursuant to this Article 6 to any Indemnified Person shall be reduced (i) by any amounts actually received by such Indemnified Person after the Closing Date pursuant to the terms of any insurance policies covering such Loss and (ii) by the amount of any net tax benefit arising from the Loss that results in a reduction of a tax liability that otherwise must be paid by the Indemnified Person (or an Affiliate of the Indemnified Person) for the tax year in which the Loss is incurred. The creation of tax attributes that do not result in a reduction of a tax liability that otherwise must be paid by the Indemnified Person (or an Affiliate of the Indemnified Person) for the tax year in which the Loss is incurred will not be taken into consideration for purposes of this Section 6.6. 6.7 Stockholder Agents. Whenever any notice is required to be given to, or any action is to be taken by, the Stockholders under this Article 6, that notice will be given to, and that action will be taken by, the Stockholder Agents acting on behalf of all of the Stockholders. -36- ARTICLE 7 GENERAL PROVISIONS 7.1 Payment of Expenses. The Acquiror, on the one hand, and (except to the extent shown on the Company Financial Statements) each Stockholder and each Spun-Off Subsidiary, on the other hand, each will pay its own expenses incident to preparing for entering into and carrying out this Agreement and the consummation of the transactions contemplated hereby (including without limitation any expenses in any way related to the Spin-Off), whether or not the Merger is consummated. 7.2 Survival of Representations and Warranties. (a) Except for the representations and warranties that have longer survival periods as described in Section 7.2(b), (i) all of the representations and warranties contained in Article IV will not expire at the Effective Time, but rather will survive the Effective Time and will terminate at 11:59 p.m., Central Time, on the 180th day following the Effective Time, and (ii) all of the representations and warranties contained in Article III will not expire at the Effective Time, but rather will expire 30 days after the filing of Acquiror's report on Form 10-K for the year ended December 31, 2002.
