The Escrow Agent hereby agrees to act as escrow agent and to hold, safeguard and disburse the Escrow Amount pursuant to the terms and conditions hereof. 4. INVESTMENT OF FUNDS Except as the Purchaser and the Principal Stockholders may from time to time jointly instruct the Escrow Agent in writing, the Escrow Amount shall be invested from time to time, to the extent possible, in an interest bearing investment account approved by the Purchasers and the Principal Stockholders with the Escrow Agent, until disbursement of the entire Escrow Amount.

All profit derived from any investment of any part of the Escrow Amount, together with all interest earned on the Escrow Amount, shall be included within the definition of the term "Escrow Amount" for purposes of this Escrow Agreement. 5. RETENTION OF ESCROW AMOUNT The Escrow Agent shall hold the Escrow Amount in escrow to secure the obligations of the Principal Stockholders set forth in the Stock and Asset Purchase Agreement and shall release the Escrow Amount, and any part thereof, only in accordance with the provisions of this Escrow Agreement. 6. NOTICE AND PAYMENT OF CLAIMS: RETENTION AND RELEASE OF AMOUNTS IN ESCROW 6.1 Purchaser's Notice. At any time during the period commencing on the date hereof and ending six (6) months thereafter (the "Holdback Period"), the Purchasers may deliver a notice signed by an officer of the Purchaser (a "Notice") to the Principal Stockholders and the Escrow Agent (i) stating that the Principal Stockholders are obligated to make a payment to the Purchaser pursuant to Section 5 of the Stock and Asset Purchase Agreement in respect of any loss, damage, deficiency, liability or obligation included within the definition of "Damages" or otherwise the subject of Section 5 of the Stock and Asset Purchase Agreement (each, a "Damage"), and identifying which of those Sections gives rise to the Principal Stockholders' obligation; (ii) specifying in reasonable detail the nature, the underlying facts, and, to the extent determinable at the time of such Notice, the dollar amount or a good faith approximation thereof; together with the Purchaser's calculations with respect thereto (a "Claim Amount") of any claim for indemnification (a "Claim") it may have under Section 5 of the Stock and Asset Purchase Agreement; and (iii) confirming that such Claim is not subject to the limitations on the Principal Stockholders' indemnification obligations set forth in Section 5.3 of the Stock and Asset Purchase Agreement. The Purchasers may make more than one claim with respect to any underlying state of facts, but shall only be entitled to a single recovery in respect of any single Damage or amount which is the subject of Section 5 of the Stock and Asset Purchase Agreement. The Escrow Agent shall not inquire into or consider whether a Claim complies with the requirements of the Stock and Asset Purchase Agreement. 6.2 Principal Stockholders' Counter Notice. Within ninety (90) days of receipt of a Notice, the Principal Stockholders may deliver to the Purchasers and to the Escrow Agent a notice (a "Counter Notice") signed by each Principal Stockholder delivering such Counter Notice (i) setting forth their acquiescence to or rejection of the Claim in its totality, or of their partial acceptance of the Claim; (ii) specifying that part of the Claim to which acquiescence is made and that part which is rejected; (iii) as to each part of the Claim which is rejected, specifying whether the Principal Stockholders reject their 2. obligation to indemnify the Purchasers in respect thereof, whether the Principal Stockholders accept their obligation to indemnify the Purchasers in respect thereof but reject the amount of the Claim or both; provided, however, that if the Principal Stockholders have waived their right to dispute their obligation to indemnify the Purchasers in respect of any Claim under the terms of the Stock and Asset Purchase Agreement, they shall not have the right to reject any Claim on the basis of any such asserted waiver; and (iv) setting forth in reasonable detail the nature of and the facts underlying their rejection of any part of the Claim. 6.3 Accepted Claims. Any Claim or portion of any Claim which is not disputed in a Counter Notice timely delivered by the Principal Stockholders shall be referred to as "Accepted." Failure by the Principal Stockholders timely to deliver a Counter Notice in response to any Notice shall be deemed to be an acceptance of the validity of the Claim set forth in such Notice and a waiver of any right to contest the validity or amount of such Claim, and the amount of the entire Claim shall be deemed "Accepted." 6.4 Unresolved Claims. Any Claim or portion of a Claim which is disputed in a Counter Notice shall be resolved in accordance with Section 7, and, pending such resolution, shall be referred to as "Unresolved." The entire amount of any Claim shall be deemed "Unresolved" between the date of the Notice setting forth such Claim, and (i) the date on which a Counter Notice is delivered in respect of such Claim, and (ii) the last date on which a Counter Notice may be delivered in respect of such Claim under Section 6.2, whichever is earlier. 6.5 Retention of Escrow Amount. Except as set forth in Section 6.6, the Escrow Agent shall retain a portion of the Escrow Amount sufficient to pay the amount of all Unresolved Claims. 6.6 Release of Escrow Amounts. The Escrow Agent shall: (i) pay to the Purchasers, on the ninety-fifth (95th) day after receipt of any Notice, the Accepted amount of the Claim set forth in such Notice; (ii) make such payments to the Purchasers or the Principal Stockholders as required under Section 7; and (iii) release to the Principal Stockholders at the termination of the Holdback Period the Escrow Amount, if any, in excess of the aggregate amount of any Claims which are then Unresolved. 7. UNRESOLVED CLAIMS The Escrow Agent shall not pay any amounts in respect of any Claim or portion thereof which is Unresolved except in accordance with the following: 7.1 Joint or Counterpart Instructions for Payment of Unresolved Claims. If the Purchasers and the Principal Stockholders resolve their differences by negotiation as to the portion of any Claim which is Unresolved, they shall deliver joint or counterpart instructions to the Escrow Agent setting forth the agreement between them. The Escrow Agent shall be entitled to rely on any such joint or counterpart instructions and shall promptly pay amounts to the Purchasers or to the Principal Stockholders as set forth in the joint or counterpart instructions. 7.2 Arbitral or Judicial Decision with Respect to Unresolved Claims. If the Purchasers and the Principal Stockholders are not able to resolve their differences as to the portion of any Claim which is Unresolved within fifteen (15) days of receipt by the Purchasers of the Counter Notice identifying such Unresolved Claim amount, either of the Purchasers or the Principal Stockholders may initiate arbitration to resolve those differences under Section 13. The Escrow Agent shall pay amounts in respect of any such Unresolved Claim only upon receipt of (i) joint or counterpart instructions setting forth an agreement between the Purchasers and the Principal Stockholders with respect to the payment of such Unresolved Claim or part thereof, or (ii) an arbitration decision or a final non-appealable judgment or court order presented by the Purchasers or the Principal Stockholders stating whether the Principal 3.

TERMINATION OF ESCROW This Escrow Agreement shall terminate when the entire Escrow Amount has been distributed in accordance with the provisions of this Escrow Agreement. 9. DUTIES OF THE ESCROW AGENT 9.1 The Escrow Agent shall not be under any duty to give the Escrow Amount held by it hereunder any greater degree of care than it gives its own similar property and shall not be required to invest any funds held hereunder except as directed in this Escrow Agreement.

Without limiting the foregoing, the Escrow Agent shall in no event be liable in connection with its investment or reinvestment of any cash held by it hereunder in good faith, in accordance with the terms hereof, including, without limitation, any liability for any delays (not resulting from its gross negligence or willful misconduct) in the investment or reinvestment of the Escrow Amount, or any loss of interest incident to any such delays. 9.3 The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof. The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume that the person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so. The Escrow Agent may conclusively presume that the undersigned representative of any party hereto which is an entity other than a natural person has full power and authority to instruct the Escrow Agent on behalf of that party unless written notice to the contrary is delivered to the Escrow Agent. 9.4 The Escrow Agent may act pursuant to the advice of counsel with respect to any matter relating to t. his Escrow Agreement and shall not be liable for any action taken or omitted by it in good faith in accordance with such advice. 9.5 The Escrow Agent does not have any interest in the Escrow Amount deposited hereunder but is serving as escrow holder only and having only possession thereof.

The resignation of the Escrow Agent will take effect on the earlier of (i) the appointment of a successor escrow agent (which may include a court of law) or (ii) the day which is sixty (60) days after the date of delivery of its written notice of resignation to the other parties hereto. If at that time the Escrow Agent has not received a designation of a successor escrow agent, the Escrow Agent's sole responsibility after that time shall be to retain and safeguard the Escrow Amount until receipt of a designation of successor escrow agent or a joint written disposition instruction by the other parties hereto or a final non-appealable order of a court of law. 9.7 In the event of any disagreement between the other parties hereto resulting in adverse claims or demands being made in connection with the Escrow Amount, or any portion thereof, or in the event that the Escrow Agent is in doubt as to what action it should take hereunder, the Escrow Agent shall be entitled to retain such portion of the Escrow Amount corresponding to such adverse claims or as to which it is in doubt as to what action it should take (the "Amount in Question") until it has received (i) joint or counterpart instructions setting forth an agreement between the Purchasers and the Principal Stockholders with respect to the disposition of the Amount in Question, or (ii) an arbitration decision or a final non-appealable judgment or court order presented by the Purchasers or the Principal Stockholders setting forth the disposition of the Amount in Question.

Any arbitration decision or court order shall be accompanied by a legal opinion by counsel for the presenting party satisfactory to the Escrow Agent to the effect that the arbitration decision or order is final and non-appealable. The Escrow Agent shall act on such arbitration decision or court order and legal opinion as provided herein without further question. 9.8 The Escrow Agent's fees and expenses for acting as the Escrow Agent hereunder are set forth in Schedule A hereto.
