(a) The aggregate number of shares of AB's common stock, par value $.01 per share (the "AB Common Stock"), issuable to the holders of the Common Stock at the Effective Time (the "Initial Stock Payment") shall be 56,818; however, in lieu of issuing any fractional shares which each Stockholder would otherwise receive based upon a pro rata allocation, AB shall be entitled to pay the holders of Common Stock cash in an amount equal to such fraction multiplied by $8.80 (the "Initial Payment Market Value Price"). The aggregate Per Share Initial Stock Payment (as described below) for each Stockholder is set forth on EXHIBIT A next to such Stockholder's name, such aggregate Per Share Initial Stock Payment being equal to each Stockholder's pro rata portion of the Initial Stock Payment (on a per share basis, the "Per Share Initial Stock Payment").

(c) The Per Share Initial Stock Payment and the Per Share Cash Payment shall be paid to the Stockholders at the addresses as set forth on EXHIBIT A attached hereto. 1.7 ADDITIONAL PAYMENTS.

The corresponding Per Share Additional Payment shall be the quotient obtained by dividing: (i) the total number of shares which constitute the Additional Payment to be issued upon the occurrence of a particular Additional Payment Event by (ii) the Fully-Diluted Share Number; PROVIDED, HOWEVER, that in lieu of issuing any fractional shares, AB shall be entitled to pay the holders of Common Stock immediately prior to the Effective Time cash in an amount equal to such fraction multiplied by the Additional Payment Market Value Price. Any Per Share Additional Payment shall be paid to the Stockholders at the addresses set forth on EXHIBIT A hereto promptly following the applicable Additional Payment Determination Date. Any shares of AB Common Stock issued as an Additional Payment shall be subject to registration with the SEC in accordance with the terms and conditions of the Registration Rights Agreement.

Each Additional Payment Event listed above may be achieved on one occasion only, so that a maximum of two Additional Payments could be earned if a determination is made that both of the above-referenced Additional Payment Events had been achieved and a minimum of zero Additional Payments could be earned if a determination is made that neither of the above-referenced Additional Payment Events has been achieved by the Expiration Date. (c) The determination of whether either of the above performance goals has been achieved by the Surviving Corporation shall be made by the Board of Directors of AB in good faith (the date of any such determination being referred to herein as an "Additional Payment Determination Date"). Any controversy or dispute among the parties hereto arising in connection with such determination shall be resolved in accordance with Section 10.12. (d) Notwithstanding anything in this Agreement to the contrary, any Additional Payment shall be subject to set-off against any indemnification obligations arising under Section 9.1 of this Agreement. 1.8 VESTING PAYMENT.

The Vesting Payment may be achieved on one occasion only. Any controversy or dispute among the parties 5 11 hereto arising in connection with the Vesting Payment shall be resolved in accordance with Section 10.12.

Notwithstanding the foregoing, the right of Buyer Indemnified Parties to indemnification under Section 9.1 shall be subject to the following provisions: (a) No indemnification shall be payable pursuant to Section 9.1(b) (exclusive of any claims related to ownership of the Common Stock), 9.1(e) or 9.1(f) to any Buyer Indemnified Party unless the total of all claims for indemnification pursuant to Section 9.1 shall exceed $200,000 in the aggregate, whereupon the full amount of such claims shall be recoverable in accordance with the terms hereof; (b) No indemnification shall be payable to a Buyer Indemnified Party with respect to claims asserted pursuant to Section 9.1(b) (exclusive of any claims related to ownership of the Company's Common Stock or any of the matters set forth in Section 2.23) or 9.1(e) after the third anniversary of the date hereof and claims asserted pursuant to 9.1(c) after all of the applicable statutes of limitations for such claims have expired; (c) No indemnification shall be payable pursuant to Section 9.1 after the cumulative amount of any claims paid by the Principal Stockholder to or on behalf of the Buyer Indemnified Parties exceeds $2,000,000; PROVIDED, HOWEVER, that the foregoing limitation shall not apply to any claims paid relating to ownership of the Company's Common Stock or any of the matters set forth in Section 2.23 or any of the matters set forth in Sections 9.1(a), 9.1(d) or 9.1(f); and (d) The right of the Buyer Indemnified Parties to indemnification with respect to any matters set forth in Sections 9.1(a), 9.1(d), 9.1(e) or 9.1(f) shall not be limited by the foregoing provisions of this Section 9.2 notwithstanding that such matters might also constitute a breach for which indemnification is available under Section 9.1(b) hereof. 9.3 NOTICE; DEFENSE OF CLAIMS. A Buyer Indemnified Party may make claims for indemnification hereunder by giving written notice thereof to the Principal Stockholder within the period in which indemnification claims can be made hereunder. If indemnification is sought for a claim or liability asserted by a third party, the Buyer Indemnified Party shall also give written notice thereof to the Principal Stockholder promptly after it receives notice of the claim or liability being asserted, but the failure to do so shall not relieve the Principal Stockholder from any liability except to the extent that it is prejudiced by the failure or delay in giving such notice. Such notice shall summarize the bases for the claim for indemnification 32 38 and any claim or liability being asserted by a third party. Within 20 days after receiving such notice, the Principal Stockholder shall give written notice to the Buyer Indemnified Party stating whether it disputes the claim for indemnification and whether it will defend against any third party claim or liability at its own cost and expense. If the Principal Stockholder fails to give notice that it disputes an indemnification claim within 20 days after receipt of notice thereof, it shall be deemed to have accepted and agreed to the claim, which shall become immediately due and payable. The Principal Stockholder shall be entitled to direct the defense against a third party claim or liability with counsel selected by it (subject to the consent of the Buyer Indemnified Party, which consent shall not be unreasonably withheld) as long as the Principal Stockholder is conducting a good faith and diligent defense. The Buyer Indemnified Party shall at all times have the right to fully participate in the defense of a third party claim or liability at its own expense directly or through counsel; PROVIDED, HOWEVER, that if the named parties to the action or proceeding include both the Principal Stockholder and the Buyer Indemnified Party and the Buyer Indemnified Party is advised that representation of both parties by the same counsel would be inappropriate under applicable standards of professional conduct, the Buyer Indemnified Party may engage separate counsel at the expense of the Principal Stockholder. If no such notice of intent to dispute and defend a third party claim or liability is given by the Principal Stockholder, or if such good faith and diligent defense is not being or ceases to be conducted by the Principal Stockholder, the Buyer Indemnified Party shall have the right, at the expense of the Principal Stockholder, to undertake the defense of such claim or liability (with counsel selected by the Buyer Indemnified Party) and to compromise or settle it, exercising reasonable business judgment. If the third party claim or liability is one that by its nature cannot be defended solely by the Principal Stockholder, then the Buyer Indemnified Party shall make available such information and assistance as the Principal Stockholder may reasonably request and shall cooperate with the Principal Stockholder in such defense, at the expense of the Principal Stockholder. 9.4 SATISFACTION OF STOCKHOLDER INDEMNIFICATION OBLIGATIONS. In order to satisfy the indemnification obligations set forth in Section 9.1 above, a Buyer Indemnified Party shall have the right (in addition to collecting directly from the Principal Stockholder) to set off its indemnification claims against any Additional Payments or the Vesting Payment to be issued or paid to the Stockholders. For purposes of determining the number of shares of AB Common Stock to be offset, the value of the shares constituting an Additional Payment shall be the Additional Payment Market Value Price as determined in accordance with Section 1.7 and the value of the shares constituting the Vesting Payment shall be $8.80. SECTION 10. MISCELLANEOUS. 10.1 FEES AND EXPENSES. (a) Except as provided in Sections 7.2(b) and 10.1(b), each of the parties will bear its own expenses in connection with the negotiation and the consummation of the transactions contemplated by this Agreement, and no expenses of the Company or the Principal Stockholder relating in any way to the purchase and sale of the Common Stock hereunder and the transactions contemplated hereby, including, without 33 39 limitation, investment banking, brokerage, legal, accounting or other professional expenses of the Company or the Principal Stockholder, shall be charged to or paid by the Company, the Surviving Corporation, Acquisition Corp or AB. (b) The parties acknowledge that AB has advanced $25,000 (the "Advance") to the Company to be used solely for the Company's expenses incurred in connection with the negotiation and consummation of the transactions contemplated by this Agreement. In the event such transactions are consummated, (i) the aggregate cash payment to be made to the Stockholders at the Closing will be reduced by $12,500 as provided in Section 1.6(b), and (ii) the value of the first, as a matter of time, to be made of the Additional Payments will be reduced by $12,500 as provided in Section 1.7(a). In the event this Agreement is terminated, the Advance shall be credited against fees for contract screening services provided by the Company for AB, and absent such recoupment of the Advance in full by the first anniversary of the date of such termination, shall be repaid to AB within 30 days after such first anniversary. In the event the Merger is consummated but no Additional Payment Date has occurred prior to the Expiration Date, the Stockholders shall be jointly and severally liable for the repayment to AB within 30 days after the Expiration Date of the $12,500 of the Advance which has not been recouped by AB. 10.2 GOVERNING LAW. This Agreement shall be construed under and governed by the internal laws of The Commonwealth of Massachusetts without regard to its conflict of laws provisions, except for such portion of this Agreement which specifically reference statutory provisions of the State of Colorado, to which Colorado law shall apply. 10.3 NOTICES. Any notice, request, demand or other communication required or permitted hereunder shall be in writing and shall be deemed to have been given if delivered or sent by facsimile transmission, upon receipt, or if sent by registered or certified mail, upon the sooner of the date on which receipt is acknowledged or the expiration of three days after deposit in United States post office facilities properly addressed with postage prepaid.
