Stockholder Rights. While any MLC Common Shares are held in the ------------------- Escrow Deposit, and pending the disbursement thereof to MLC or the Stockholders, as the case may be, in connection with any disbursement of property from the Escrow Deposit in accordance with Section 2, the Stockholders shall have all rights with respect thereto (including, without limitation, the right to vote such shares), except (i) the right of possession thereof, (ii) the right to assign or pledge such shares or any interest therein and (iii) the right to possession of any dividends or other distributions received in respect thereof. 1.4. Stockholder Percentage Interest in Escrow Deposit. Attached hereto as ----------------------------------------------------- Schedule 1.4 is a schedule listing each Stockholder, such Stockholder's address and Social Security or other tax identification number and such Stockholder's interest in the Escrow Deposit (expressed as a percentage, based on the number of Escrowed Shares delivered to the Escrow Agent at the Closing Date on behalf of such Stockholder). 1.5. Merger Share Price. The average share price is $13.50 per Escrowed Share ------------------- (the "Merger Share Price"). 2 SECTION 2 DISPOSITION OF ESCROW DEPOSIT 2.1. Term of Escrow Deposit. ---------------------- 2.1.a. The Escrowed Shares held in the Escrow Deposit shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Merger Agreement (but the Escrow Agent shall have no responsibility with respect to the Merger Agreement other than to perform as provided in this Agreement) to satisfy the indemnification obligations of the Stockholders pursuant to Section 12 of the Merger Agreement. The Escrow Agent shall release a portion of the Escrow Deposit to the Representative on the close of business on the first anniversary of the Closing Date (the "Initial Expiration Date"), subject to the terms and conditions set forth in Sections 2.7(a) and 2.8. 2.1.b. The Escrowed Shares held in the Escrow Deposit after the Initial Expiration Date shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Arrow Agreement until the first anniversary of the Closing Date (the "Final Expiration Date" and collectively with the Initial Expiration Date, the "Expiration Dates"). Notwithstanding the foregoing, any amount that constitutes a Claim Reserve (as defined in Section 2.6) shall be released prior to the Final Expiration Date in accordance with Section 2.8. On the Final Expiration Date, the Escrow Agent shall release the remaining Escrowed Purchase Price held in the Escrow Deposit to the Selling Persons, subject to the terms and conditions set forth in Sections 2.7(b) and 2.8 2.2. MLC Indemnity Claims. In the event of the occurrence of an event which MLC --------------------- in its reasonable judgment asserts constitutes a MLC Indemnity Claim (as defined in the Merger Agreement), MLC shall furnish notice of such event (the "Indemnity Notice") to the Representative and the Escrow Agent promptly (and in any event on or prior to the Expiration Date), setting forth MLC's then good-faith estimate of the reasonably foreseeable maximum amount of its MLC Indemnity Claim, and shall make available to the Representative all relevant information which is material to such MLC Indemnity Claim and which is in the possession of MLC. 2.3. MLC Indemnity Claims Not Disputed by Representative. If, within thirty (30) ---------------------------------------------------- days after receipt of the Indemnity Notice, the Representative does not give the notice provided for in Section 2.4, MLC shall be entitled to make demand upon the Escrow Agent that it retain for future return to MLC as and when the amount is determined, if the amount is not then determined, or that it then disburse to MLC, if the amount has then been determined, a number of Escrowed Shares having a value equal to the lesser of (i) the full amount set forth in the Indemnity Notice (plus the value of all property held in the Escrow Deposit which arose in respect of dividends and distributions on such Escrowed Shares) or (ii) the entire Escrow Deposit. For purposes of this Agreement, the value of each Escrowed Share returned to MLC in satisfaction of MLC Indemnity Claims shall be calculated based upon the Merger Share Price. 3 2.4. MLC Indemnity Claims Disputed by Representative in Whole. If the ----------------------------------------------------------------- Representative disputes either the MLC Indemnity Claim described in the Indemnity Notice or the amount MLC seeks as indemnity on account of such MLC Indemnity Claim, the Representative shall, within thirty (30) days after his receipt of the Indemnity Notice, notify the Escrow Agent and MLC of such dispute, setting forth the basis therefor in reasonable detail, based on his then good-faith belief. In the event the Representative disputes the entire MLC Indemnity Claim, the Escrow Agent shall not distribute any amount with respect thereto until the Escrow Agent receives a written agreement signed the Representative and MLC stating the amount to which MLC is entitled in connection with such MLC Indemnity Claim, or a copy of a court order or judgment together with an opinion of counsel reasonably acceptable to the Escrow Agent to the effect that such order or judgment is a final order or judgment of a court of competent jurisdiction binding on MLC and the Stockholders from which no appeal may be taken or for which the time to appeal has expired (a "Final Judgment"), at which time the Escrow Agent shall disburse to MLC the lesser of (i) a number of Escrowed Shares having a value (based on the Merger Share Price) equal to the amount set forth in such agreement or Final Judgment (plus the value of all property held in the Escrow Deposit which arose in respect of dividends and distributions on such Shares) or (ii) the entire Escrow Deposit. 2.5. MLC Indemnity Claims Disputed by Representative in Part. In the event the ---------------------------------------------------------- Representative disputes part of, but not all of, a MLC Indemnity Claim, the Escrow Agent shall, if the amount is undetermined, retain for future return to MLC, or, if the amount is determined, return to MLC, the lesser of (i) a number of Escrowed Shares having a value (based on the Merger Share Price) equal to an amount attributable to that portion of the MLC Indemnity Claim which is not disputed by the Representative (together with all property held in the Escrow Deposit which arose in respect of dividends and distributions on such Escrowed Shares) or (ii) the entire Escrow Deposit. The Escrow Agent shall not distribute any amount with respect to the balance of such MLC Indemnity Claim except in accordance with the procedures set forth in Section 2.4. 2.6. Notice to Withhold on the Expiration Dates. On or prior to the any of the -------------------------------------------- Expiration Dates, MLC shall notify the Escrow Agent and the Representative of the amount, if any, to be retained on account of MLC Indemnity Claims concerning which MLC has given the notice specified in Section 2.2 which, in its reasonable judgment, continue to constitute MLC Indemnity Claims and which are not, at such time, absolute as to liability or liquidated as to amount, such notice to contain the information specified in Section 2.2 to the extent it requires supplementation or change based on MLC's knowledge on the notice date, whereupon the Escrow Agent shall retain that portion of the Escrow Deposit (the "Claim Reserve") having a value (determined in accordance with the last sentence of Section 2.3 with respect to Escrowed Shares) equal to the amount set forth in the notice given by MLC pursuant to this Section 2.6 (plus all property held in the Escrow Deposit which constitutes, or arose in respect of, dividends, distributions or interest on the Escrow Deposit). In the event MLC does not timely provide the notice required by this Section 2.6, and continues to fail to provide such notice within ten (10) business days after delivery by th 4 Representative to MLC (with a copy to the Escrow Agent) of a demand that the notice required by this Section 2.6 be delivered, all remaining property held in the Escrow Deposit shall be distributed by the Escrow Agent to the Stockholders in accordance with Section 2.7. 2.7. Distribution Following Expiration Dates. ----------------------------------------- 2.7.a. As soon as practicable following the Initial Expiration Date, one-half of the Escrowed Shares and such other property as shall remain in the Escrow Deposit after deduction of (i) all portions of the Escrow Deposit required by MLC to be retained pursuant to notice given under Section 2.6 as a Claim Reserve and (ii) all property held in the Escrow Deposit which constitutes, or arose in respect of, dividends, other distributions or interest on the Escrow Deposit referred to in clause (i) of this sentence shall be released from the provisions of this Agreement and distributed promptly by the Escrow Agent, as directed by the Representative, to the Stockholders, by a nationally recognized overnight courier (at the risk of the Stockholders) to such persons at the address as shall have been specified in a written notice to the Escrow Agent from the Representative, with any cash amounts paid by wire transfer to an account designated in writing by the Representative. In any such notice, the Representative shall designate how much of the amount to be released pursuant to Section 2.7(a) shall be payable in the form of Escrowed Shares valued at the Average Share Price and how much shall be payable in the form of cash.. 2.7.b. As soon as practicable following the Final Expiration Date, the remaining portion of the Escrow Deposit after deduction of (i) all amounts of the Escrow Deposit required by MLC to be retained pursuant to notice given under Section 2.6 and (ii) all property held in the Escrow Deposit which constitutes, or arose in respect of, dividends, other distributions or interest on the Escrow Deposit referred to in clause (i) of this sentence shall be released from the provisions of this Agreement and distributed promptly by the Escrow Agent, as directed by the Representative, to the Stockholders, by registered or certified first class mail to such persons at the address as shall have been specified in a written notice to the Escrow Agent from the Representative, with any cash amounts paid in the form of a check issued by and drawn on the Escrow Agent. 2.8. Retention of Escrow Deposit After Expiration Dates. Upon receipt of a -------------------------------------------------------- notice pursuant to Section 2.6, the Escrow Agent shall continue to hold after the Expiration Dates, with respect to each MLC Indemnity Claim included in such notice, the Claim Reserve until such time as the Escrow Agent receives a written agreement signed by the Representative and MLC stating the amount, if any, to which MLC is entitled from the Escrow Deposit in connection with such MLC Indemnity Claim, or a copy of a Final Judgment with respect to such MLC Indemnity Claim, at which time the Escrow Agent shall return to MLC, with respect to such MLC Indemnity Claim, the portion of the Claim Reserve having a value (determined in accordance with the last sentence of Section 2.3 with respect to Escrowed Shares) equal to the amount specified in such agreement or Final Judgment (plus the value of all property held in the Escrow Deposit which 5 constitutes, or arose in respect of, dividends, distributions or interest on the amount of the Claim Reserve to be distributed to MLC) and shall distribute, as directed by the Representative, to the Stockholders, the remainder of the Claim Reserve plus all property held in the Escrow Deposit which constitutes, or arose in respect of, dividends, distributions or interest on such remainder; provided, however, that, to the extent the distribution of the remainder of the Claim Reserve to the Stockholders would cause the value of the property remaining in the Escrow Deposit after such distribution to fall below the amount (as stipulated in MLC's Section 2.6 notice) of all still unresolved MLC Indemnity Claims identified in the Section 2.6 notice, such remainder shall be retained by the Escrow Agent in the Escrow Deposit and shall be available for distribution to MLC upon the resolution of any unresolved MLC Indemnity Claims, and such remainder shall not be distributed to the Stockholders until such time, if any, as such distribution can be made without causing the value of all property remaining in the Escrow Deposit to fall below the amount of all remaining unresolved MLC Indemnity Claims identified in the Section 2.6 notice. 2.9. Allocation of Escrowed Shares Distributed to MLC. In the event Escrowed ----------------------------------------------------- Shares are retained by the Escrow Agent or distributed to MLC pursuant to any provisions of this Section 2, such Escrowed Shares shall be taken from the Escrowed Shares deposited by each Stockholder in proportion to such Stockholder's percentage interest in the Escrow Deposit as set forth on Schedule 1.4. 2.10.

All cash held in the Escrow Deposit shall be ----------------------------- invested by the Escrow Agent in Crestfunds US Treasury Money Funds, so long as such fund is rated in the highest investment category by Standard & Poor's Rating Group or Moody's Investors Service, Inc., or in such other investments as MLC and the Representative may agree in a writing delivered to the Escrow Agent. In the event that the Crestfunds US Treasury Money Funds shall cease to be rated in the highest investment category by Standard & Poors Rating Group or Moody's Investment Service, Inc., the Escrow Agent shall notify MLC and the Representative in writing and promptly deposit all cash held in the Escrow Deposit in a fund that has such rating until such time as MLC and the Representative shall direct the Escrow Agent in writing to deposit such funds 6 elsewhere.
