The sole purpose of the Escrow Account shall be to fund payment of any Purchase Price Adjustment (defined below). Purchaser shall pay for any and all costs of transporting the Purchased Assets; Purchaser shall make immediate arrangements for such transport. Each party shall bear one-half of all sales, transfer and documentary stamp taxes imposed upon the transfer of the Transferred Items.

Within fifteen days after the Inventory Settlement, the Purchase Price shall be adjusted (the amount of any such adjustment, the “Purchase Price Adjustment”), and Seller shall make payment to Purchaser of any such Purchase Price Adjustment (first through a distribution from the Escrow Account and the balance, if any, in immediately available funds) as final reconciliation of the Purchase Price, to account for Purchased Assets that are listed on Schedule A but not delivered at the time the Transferred Assets are transported to Purchaser, which Purchaser Price Adjustment, if any, shall be based on the actual Purchased Assets delivered and the value for each Purchased Assets as set forth in Schedule A, provided that no adjustment to the Purchase Price shall occur unless the decrease to the Purchase Price (on a net basis taking into account all overages and underages of delivered Purchased Assets) exceeds FIFTY THOUSAND DOLLARS ($50,000.00) (“Purchase Price Adjustment Threshold”), provided further that any underdelivery of the 25 doors identified on Schedule A as Key Number T066-0000 (DOOR HWR TA GLASS AS STYLE) shall constitute a dollar for dollar decrease to the Purchase Price and shall not be subject to the Purchase Price Adjustment Threshold.

The Purchase Price Adjustment shall be implemented as follows:

(i) If Purchaser determines that a Purchase Price Adjustment is required, it shall deliver to Seller written notice of such determination which notice, to be effective, shall (a) be actually received by Seller within fifty calendar days of the Effective Date and (b) include written support to substantiate Purchaser’s position (“Purchase Price Adjustment Notice”).

(ii) If Purchaser delivers to Seller a timely Purchase Price Adjustment Notice, Purchaser and Seller shall attempt in good faith during the ten days immediately following Seller’s receipt of such notice to resolve any disagreement with respect to a Purchase Price Adjustment. If the parties reach

settlement regarding their disagreements related to the Purchase Price Adjustment, the parties shall enter into a written settlement regarding such disagreements (“Inventory Settlement”). If, at the conclusion of such ten day period, the Purchaser and Seller have not resolved their disagreements regarding the Purchase Price Adjustment, either party may pursue any remedy it deems appropriate to resolve such disagreement.

(iii) If within the fifty day period immediately following the Effective Date, the Purchaser does not deliver to Seller a Purchase Price Adjustment Notice, no Purchase Price Adjustment shall occur and the Purchase Price shall be deemed final.

Purchaser and Seller acknowledge that as of the Effective Date, Seller has continuing rental obligations for its customers which require the continued use of the Purchased Assets specified on Schedule C hereto (“Deployed Purchased Assets”). Purchaser hereby rents to Seller the Deployed Purchased Assets for the periods and for the rental rates specified in Schedule C for such Deployed Purchased Assets.

The Buyer and the Company shall be referred to herein as the “Interested Parties”. Capitalized terms used and not otherwise defined herein shall have the meaning as assigned to such terms in the Bill of Sale (defined below).

A. The Buyer, the Company and Signature Special Event Services, Inc., a Maryland corporation have entered into a Bill of Sale and Assignment of Contract Rights, of even date herewith, (the “Bill of Sale”) pursuant to which the Buyer has purchased certain the assets and assumed certain contracts of the Company.

B. Pursuant to the Bill of Sale, the Buyer will deposit a portion of the Purchase Price (as defined in the Bill of Sale) in escrow with the Escrow Agent to be held and distributed by the Escrow Agent on the terms and conditions set forth herein.

C. The parties to this Agreement hereby acknowledge and agree that the Escrow Agent has not reviewed, and is not a party to, the Bill of Sale and is not responsible for any of the duties or responsibilities set forth therein.

NOW, THEREFORE, in consideration of the mutual promises and agreements set forth in this Agreement, the parties hereto hereby agree as follows:

1. Appointment of Escrow Agent; Deposit of Escrowed Funds. The Buyer hereby deposits with the Escrow Agent, and the Escrow Agent hereby acknowledges receipt of, the sum of TWO HUNDRED SEVENTY THOUSAND dollars ($270,000) (together with interest and other income, if any, earned thereon, the “Escrowed Funds”) as funding for certain claims by the Buyer pursuant the Bill of Sale. Subject to the provisions of Section 2 hereof, the Escrowed Funds shall be deposited by the Escrow Agent in Account No. #                  and shall be maintained in such account until the release of the Escrowed Funds in accordance with Section 3 hereof. The Escrow Agent, by signing this Agreement, accepts the appointment as Escrow Agent and agrees to hold and distribute the Escrowed Funds in accordance with the terms of this Agreement.

2. Investment of Escrowed Funds. During the term of this Agreement, the Escrowed Funds shall be invested in a Union Bank of California Money Market Account Trust Unlimited (an interest bearing deposit account of the Escrow Agent.)*, unless otherwise instructed in writing by the Interested Parties and as shall be acceptable to the Escrow Agent. Such written instructions, if any, referred to in the foregoing sentence shall specify the type and identity of the investments to be purchased and/or sold. The Escrow Agent is hereby authorized to execute purchases and sales of investments through the facilities of its own trading or capital markets operations or those of any affiliated entity. An agency fee may be assessed in connection with each transaction. In the event that the Escrow Agent does not receive written instructions to invest funds held in the Escrowed Funds, the Escrow Agent shall invest such funds in a Union

Bank of California Money Market Account Trust Unlimited (an interest bearing deposit account of the Escrow Agent.) or a successor or similar investment offered by the Escrow Agent. The Escrow Agent shall have the right to liquidate any investments held in order to provide funds necessary to make required payments under this Agreement. The Interested Parties recognize and agree that the Escrow Agent will not provide supervision, recommendations or advice relating to either the investment of moneys held in the Escrowed Funds or the purchase, sale, retention or other disposition of any investment described herein. The Escrow Agent shall not have any liability for any loss sustained as a result of any investment in an investment made pursuant to the terms of this Agreement or as a result of any liquidation of any investment prior to its maturity or for the failure of the Interested Parties to give the Escrow Agent instructions to invest or reinvest the Escrowed Funds. The Escrow Agent or any of its affiliates may receive compensation with respect to any investment directed hereunder. Receipt, investment and reinvestment of the Escrow Deposit shall be confirmed by Escrow Agent as soon as practicable by account statement, and any discrepancies in any such account statement shall be noted by the Interested Parties to the Escrow Agent within thirty (30) calendar days after receipt thereof. Failure to inform Escrow Agent in writing of any discrepancies in any such account statement within said thirty (30) day period shall conclusively be deemed confirmation of such account statement in its entirety.

3. Release of Escrowed Funds.

(a) Release of Escrowed Funds.

(i) Subject to the provisions of paragraph (ii) below, the Escrowed Funds shall only be distributed and released pursuant to joint written instructions executed by the Company and the Buyer or by order of a court of competent jurisdiction which is final and not subject to further court proceedings or appeal (an “Order”).

(ii) On January 28, 2008 (the “Escrow Termination Date”), the Escrow Agent shall release to the Company the Escrowed Funds, if and to the extent any are available for distribution in accordance with the allocation specified by the Company in writing, except to the extent the Buyer has delivered to the Escrow Agent one or more written notices (a “Claim” or “Claims”) of any claims (which shall include the amount of such Claims (the “Claims Amount”)) made by the Buyer under the Bill of Sale. The Claims Amount (to the extent of the remaining portion of the Escrowed Funds) shall continue to be held by the Escrow Agent after the Escrow Termination Date until such time as all such Claims are resolved, at which time the Claims Amount remaining in the Escrow Account shall be disbursed to the Company and/or the Buyer in accordance with either (x) joint written instructions executed by the Sellers and the Buyer or (y) an Order.

2

(b) Liquidation of Investments. If necessary to satisfy any distributions under this Agreement, including distributions for the Escrow Agent’s fees and expenses not paid directly by the Interested Parties as provided herein, the Escrow Agent may sell or liquidate, any one or more investments prior to maturity and the Escrow Agent shall not be liable to the Interested Parties for any loss or penalties resulting from or relating to such sale or liquidation. However, the Interested Party entitled to any such distribution may elect to extend any payment period in this Section 3 in order to avoid any loss of income or principal from a premature liquidation of an escrow investment.

(c) Distribution of Escrowed Funds. All releases of Escrowed Funds shall be made in accordance with written instructions from the proper party (or parties) to the Escrow Agent, (i) by delivery to the appropriate party at the address set forth for such party in Section 6 hereof of a bank check in the amount of such release, or by wire transfer of immediately available funds in the amount of such release to an account designated by the appropriate party, as specified in the notice directing such release, or (ii) in such other manner as agreed to between the appropriate party and the Escrow Agent.

(d) Interest on Escrowed Funds.

(i) Ownership. For purposes of federal and other taxes based on income, the parties hereto agree that the Company will be treated as the owners of the Escrowed Funds and will be obligated to report all income, if any, that is earned on, or derived from, the Escrowed Funds as income of the Company, in the taxable year or years in which such income is properly includible, and shall be obligated to pay any taxes attributable thereto.

(ii) Tax Reporting. The parties hereto agree that, for tax reporting purposes, all interest or other income earned from the investment of the Escrowed Funds in any tax year shall (A) to the extent such interest or other income is distributed by the Escrow Agent to any person or entity pursuant to the terms of this Agreement during such tax year, be reported as allocated to such person or entity, and (B) to the extent such interest or other income is not distributed by the Escrow Agent, be reported as allocated to the Company.

4. Responsibility Of Escrow Agent. The Escrow Agent shall not be responsible for the genuineness of any signature or document presented to it pursuant to this Agreement and may rely conclusively upon and shall be protected in acting upon any judicial order or decree, certificate, notice, request, consent, statement, instruction or other instrument believed by it in good faith to be genuine or to be signed or presented by the proper person hereunder, or duly authorized by such person or properly made. Notwithstanding anything to the contrary in this Agreement, prior to taking any action hereunder, the Escrow Agent may, if in doubt regarding its duties and obligations, seek instructions from the Buyer and the Company, and if such instructions are in conflict, the Escrow Agent may seek instructions or other relief (including, but not limited to, interpleader) from a court of competent jurisdiction, and further may request such evidence, documents, certificates or opinions as it may deem appropriate. The Escrow Agent

The Escrow Agent shall not be responsible for any of the agreements contained herein except the performance of its duties as expressly set forth herein. The duties and obligations of the Escrow Agent hereunder shall be governed solely by the provisions of this Agreement, and the Escrow Agent shall have no duties other than the duties expressly imposed herein and shall not be required to take any action other than in accordance with the terms hereof. The Escrow Agent shall not be bound by any notice of, or demand with respect to, any waiver, modification, amendment, termination, cancellation, rescission or supercession of this Agreement, unless in writing and signed by the Buyer, the Company and the Escrow Agent. In the event of any controversy or dispute hereunder or with respect to any question as to the construction of this Agreement, or any action to be taken by the Escrow Agent hereunder, the Escrow Agent shall incur no liability for any action taken or suffered in good faith, its liability hereunder to be limited solely to gross negligence or willful misconduct on its part. The Escrow Agent may execute any of its trusts or powers and perform any of its duties under this Agreement by or through attorneys, agents or employees. None of the provisions contained in this Agreement shall require the Escrow Agent to use or advance its own funds in the performance of any of its duties or the exercise of any of its rights or powers hereunder. In no event shall the Escrow Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. The Buyer and the Company, jointly and severally agree to indemnify and hold the Escrow Agent and its directors, officers, agents and employees harmless, and further to protect and defend the Escrow Agent (with counsel selected by the Escrow Agent) against any and all claims, liabilities, losses, damages, fines, penalties and expenses (including out-of pocket and incidental expenses and fees and expenses of outside counsel) (“Losses”) arising out of or in connection with (i) its execution and performance of this Agreement, except to the extent that such Losses are due to the bad faith, gross negligence or willful misconduct of the Escrow Agent, or (ii) its following any instructions or other directions from the Buyer and the Company, except to the extent that its following any such instruction or direction is expressly forbidden by the terms hereof. The representations and obligations of the Company, and the Buyer to the Escrow Agent in this Agreement shall survive the termination of this Agreement and shall be applicable whether or not Union Bank of California is serving as Escrow Agent. The indemnifications set forth herein are intended to and shall include the indemnification of all affected agents, directors, officers and employees of the Escrow Agent.

The Escrow Agent’s fees for its services hereunder shall be at the rate specified on Schedule 2 attached hereto, for so long as any portion of the Escrowed Funds are held by the Escrow Agent hereunder. The fees and expenses of the Escrow Agent (including the Escrow Agent’s reasonable attorneys’ fees) shall be paid by the Buyer within ten (10) days after the Escrow Agent delivers to the Interested Parties a statement thereof, and any fees and expenses not so paid by the Interested Parties shall be paid out of the Escrowed Funds and shall constitute a priority over amounts due the Company or the Buyer from

4

the Escrowed Funds. Any amounts paid to indemnify the Escrow Agent pursuant to Section 4 hereof (“Indemnification Costs”) shall also be borne equally by each (i.e. the Buyer, on the one hand, and the Company, on the other hand). To the extent that either the Buyer or the Company pay more than half of the fees and expenses of the Escrow Agent or more than half any Indemnification Costs for any reason, including, without limitation, because all of such fees and expenses and Indemnification Costs are paid out of the Escrowed Funds prior to any return of such Escrowed Funds to the Company pursuant to Section 3 of this Agreement, the other party shall promptly reimburse such party for the defaulting party’s share of such expenses and Indemnification Costs.
