2. Deposit of the Escrow Fund.

(b) All earnings on the Escrow Fund shall become part of the Escrow Fund and held by the Escrow Agent pursuant to the terms ands conditions of this Agreement.

(c) Contemporaneously with the execution and delivery of this Agreement, the Purchaser and the Representative are each delivering a Form W-9 to the Escrow Agent.

(a) If the Purchaser shall assert a claim against the Sellers for any Losses for which the Sellers may be responsible to any Purchaser Indemnified Person pursuant to Article VII of the Purchase Agreement (a “Claim”), the Purchaser shall give written notice of such Claim (a “Claim Notice”) to the Representative and the Escrow Agent. Each Claim Notice shall: (i) indicate that a Claim is being asserted; (ii) indicate in reasonable detail the amount of all Losses based upon, arising out of, asserted against, resulting from, imposed on, or otherwise in respect of such Claim (the “Claim Amount”); (iii) indicate the portion of the Escrow Fund payable to the Purchaser in connection with such Claim; and (iv) include a certification by the Purchaser that such Claim Notice has been delivered to the Representative and the Escrow Agent.

(b) The provisions of Section 5 shall apply if, within three business days (as defined below) following receipt by the Escrow Agent of a Claim Notice (the “Claim Dispute Period”), the Escrow Agent receives from the Representative a written notice objecting to the payment of the portion of the Escrow Fund set forth in the Claim Notice (a “Claim Objection Notice”). A Claim Objection Notice shall: (i) indicate the Representative’s estimate of the portion, if any, of the Escrow Fund payable to the Purchaser in connection with such Claim Notice; and (ii) include a certification by the Representative that it has been delivered to the Purchaser and the Escrow Agent. If the Escrow Agent shall receive a Claim Objection Notice prior to the expiration of the Claim Dispute Period to which such Claim Notice relates, the Escrow Agent shall nevertheless distribute to the Purchaser the portion, if any, of the Escrow Fund payable to the Purchaser, as set forth in clause (i) of the prior sentence. If the Escrow Agent shall not receive a Claim Objection Notice prior to the expiration of the Claim Dispute Period to

which such Claim Notice relates, the Escrow Agent shall distribute to the Purchaser the portion of the Escrow Fund payable to the Purchaser as set forth in the Claim Notice. As used in this Agreement, “business day” means any day except Saturday, Sunday or any other day on which commercial banks in New York, New York are authorized or required by law to remain closed.

Each Payment Notice shall: (i) indicate the amount of the Escrow Fund payable to the Representative pursuant to such Payment Notice; and (ii) include a certification by the Representative that such Payment Notice has been delivered to the Purchaser and the Escrow Agent.

(b) The provisions of Section 5 shall apply if, within three business days following receipt by the Escrow Agent of a Payment Notice (the “Payment Dispute Period”), the Escrow Agent receives from the Purchaser a written notice objecting to the payment of the portion of the Escrow Fund set forth in the Payment Notice (a “Payment Objection Notice”).

If the Escrow Agent shall receive a Payment Objection Notice prior to the expiration of the Payment Dispute Period to which such Payment Notice relates, the Escrow Agent shall nevertheless distribute to the Representative the portion, if any, of the Escrow Fund payable to the Representative, as set forth in clause (i) of the prior sentence. If the Escrow Agent shall not receive a Payment Objection Notice prior to the expiration of the Payment Dispute Period to which such Payment Objection Notice relates, the Escrow Agent shall distribute to the Representative the portion of the Escrow Fund payable to the Representative as set forth in the Payment Notice (including any earnings thereon).

5. Disposition of the Escrow Fund by Agreement of the Parties; Conflicting Demands. The Escrow Agent may dispose of all or a portion of any of the Escrow Fund in accordance with a written instruction signed by the Purchaser and the Representative, whether such disposition is pursuant to the terms of the Purchase Agreement or otherwise. If conflicting or adverse claims or demands are made or notices served upon the Escrow Agent with respect to any of the escrows provided for herein, then the Escrow Agent may refrain from complying with any such claim or demand so long as such disagreement shall continue. In so doing, the Escrow Agent shall not be or become liable for damages, losses, costs, expenses or interest to any person (as defined below) for its failure to comply with such conflicting or adverse demands. The

Escrow Agent may continue to so refrain and refuse to act until it shall have received certification satisfactory to it that such conflicting or adverse claims or demands shall have been finally determined by a court of competent jurisdiction that is not subject to further appeal or other appellate review, or shall have been settled by agreement of the parties to such controversy, in which case the Escrow Agent shall be notified thereof in a written notice signed by all such parties. The Escrow Agent may seek the advice of legal counsel in any dispute or question as to the construction of any of the provisions of this Agreement or its duties hereunder, and it shall incur no liability and shall be fully protected in respect of any action taken, omitted or suffered by it in good faith in accordance with the opinion of such counsel. The Escrow Agent may also elect to commence an interpleader or other action for declaratory judgment for the purpose of having the respective rights of the claimants adjudicated, and may deposit with the court all funds held hereunder pursuant to this Agreement; and if it so commences and deposits, the Escrow Agent shall be relieved and discharged from any further duties and obligations under this Agreement.

The Purchaser and the Representative each hereby waive personal service of any summons, complaint or other process that may be delivered by any of the means permitted for notices under Section 13.2. In any action or proceeding involving the Escrow Agent in any jurisdiction, the Purchaser and the Representative each waive trial by jury in any such jurisdiction.

8. Reliance on Documents and Experts. The Escrow Agent shall be entitled to rely upon any notice, consent, certificate, affidavit, statement, paper, document, writing or other communication (which to the extent permitted hereunder may be by telegram, cable, telex, telecopier, or telephone) reasonably believed by it to be genuine and to have been signed, sent or made by the proper person or persons, and upon opinions and advice of legal counsel (including itself or counsel for any party hereto), independent public accountants and other experts selected by the Escrow Agent.

The Escrow Agent is acting under this Agreement as a stakeholder only and shall be considered an independent contractor with respect to the Purchaser and the Representative hereunder.

agent, trust, joint venture, partnership, debtor-creditor or attorney-client relationship between or among the Escrow Agent and the Purchaser, on the one hand, or the Representative, on the other hand. This Agreement shall not be deemed to prohibit or in any way restrict the Escrow Agent’s representation (in its capacity as legal counsel) of the Purchaser or the Company or any of their respective affiliates, any of whom may be advised and/or represented by the Escrow Agent on any and all matters pertaining to this Agreement, the Purchase Agreement, the Escrow Fund or the Contemplated Transactions. The Escrow Agent’s duties and obligations hereunder are limited to those expressly set forth in this Agreement. The Escrow Agent may exercise or otherwise enforce any of its rights, powers, privileges, remedies and interests under this Agreement and applicable law or perform any of its duties under this Agreement by or through its partners, employees, attorneys, agents or designees. To the extent that the Purchaser and/or the Company may be represented by the Escrow Agent in connection with the transactions contemplated by the Purchase Agreement, the Purchaser and the Representative each hereby (i) waives any conflict of interest that may exist or occur as a result of such representation and consents to the continued representation of the Purchaser and/or the Purchaser or their affiliates by the Escrow Agent in connection with any action, suit or other proceeding relating to or arising out of this Agreement, the Purchase Agreement or the transactions contemplated hereby or thereby and (ii) acknowledges that neither the Purchaser, nor the Company nor any of their affiliates has waived any attorney-client privilege by virtue of the appointment of the Escrow Agent hereunder or the performance by the Escrow Agent of its obligations under this Agreement.

11. Indemnification. The Escrow Agent and its designees, and their respective directors, officers, partners, employees, attorneys and agents, shall be indemnified, reimbursed, held harmless and, at the request of the Escrow Agent, defended, by the Purchaser and the Representative from and against any and all claims, liabilities, losses and expenses (including, without limitation, the disbursements, expenses and reasonable fees of their respective attorneys) that may be imposed upon, incurred by, or asserted against any of them, arising out of or related directly or indirectly to this Agreement or the Escrow Fund, except such as are occasioned by the indemnified person’s own acts and omissions amounting to gross negligence or willful misconduct.

12. Resignation of Escrow Agent; Appointment of Successor Escrow Agent. The Escrow Agent may, at any time, at its option, elect to resign its duties as Escrow Agent under this Agreement by providing written notice thereof to the Purchaser and the Representative. In such event, the Escrow Agent shall transfer the Escrow Fund to a successor

independent escrow agent to be appointed by (a) the Purchaser and the Representative within 30 days following the receipt of notice of resignation from the Escrow Agent, or (b) the Escrow Agent, if the Purchaser and the Representative shall have not agreed on a successor escrow agent within the aforesaid 30-day period, as designated by the Escrow Agent in each case upon such appointment and delivery of the Escrow Fund to the successor Escrow Agent, the Escrow Agent shall be released of and from all liability under this Agreement; provided, however, that the obligations of the Purchaser and the Representative to pay expenses and to reimburse, exculpate, indemnify, hold harmless and/or defend the Escrow Agent pursuant to Sections 7, 10 and 11 shall continue in full force and effect with respect to any Escrow Agent resigning pursuant to this Section 12.

13.1 Fees and Expenses. The Purchaser and the Representative shall each be responsible for their own fees and expenses (including, without limitation, the fees and expenses of their accountants and counsel) in connection with the entering into of this Agreement and the performance by them of their obligations hereunder, except that: (i) in the event that, following delivery by the Representative of a Claim Objection Notice to the Purchaser and the Escrow Agent, the portion of the Escrow Fund actually paid to the Purchaser pursuant to the Claim Notice to which such Claim Objection Notice relates is closer to the amount set forth the Claim Notice pursuant to Section 4.1(a)(iii) than the amount set forth in the Claim Objection Notice pursuant to Section 4.1(b)(i), then the Representative shall pay all fees and expenses incurred by the Purchaser in connection with the defense of such Claim Notice; and (ii) in the event that, following delivery by the Representative of a Claim Objection Notice to the Purchaser and the Escrow Agent, the portion of the Escrow Fund actually paid to the Purchaser pursuant to the Claim Notice to which such Claim Objection Notice relates is closer to the amount set forth in the Claim Objection Notice pursuant to Section 4.1(b)(i) than the amount set forth in the Claim Notice pursuant to Section 4.1(a)(iii), then the Purchaser shall pay all fees and expenses incurred by the Representative in connection with the defense of such Claim Objection Notice.
