ESCROW AGREEMENT ESCROW AGREEMENT ("Agreement") dated [Closing Date] by and among ARPEGGIO ACQUISITION CORPORATION, a Delaware corporation ("Parent"), IRVIN E. RICHTER, AS THE TARGET STOCKHOLDERS' REPRESENTATIVE, being the representative of the former stockholders of HILL INTERNATIONAL, INC., a Delaware corporation (the "Representative"), and CONTINENTAL STOCK TRANSFER & TRUST COMPANY, as escrow agent (the "Escrow Agent"). Parent, Hill International, Inc. ("Target") and the stockholders of Target are the parties to an Agreement and Plan of Merger and Reorganization dated as of December 5, 2005 (the "Merger Agreement") pursuant to which Hill has merged with and into Parent. Pursuant to the Merger Agreement, Parent is to be indemnified in certain respects. The parties desire to establish an escrow fund as collateral security for the indemnification obligations under the Merger Agreement. The Representative has been designated pursuant to the Merger Agreement to represent all of the former stockholders of Target (the "Stockholders") and each Permitted Transferee (as hereinafter defined) of the Stockholders (the Stockholders and all such Permitted Transferees are hereinafter referred to collectively as the "Owners"), and to act on their behalf for purposes of this Agreement. Capitalized terms used herein that are not otherwise defined herein shall have the meanings ascribed to them in the Merger Agreement. The parties agree as follows: 1. (a) Concurrently with the execution hereof, each of the Stockholders is delivering to the Escrow Agent, to be held in escrow pursuant to the terms of this Agreement, stock certificates issued in the name of such Stockholder representing twelve percent (12%) of the total number of Base Shares received by such Stockholder pursuant to the Merger Agreement, together with two (2) assignments separate from certificate executed in blank by such Stockholder, with medallion signature guaranties. Of such shares, five-sixths (the "Basic Indemnity Shares") shall be available only with respect to satisfaction of claims ("Basic Indemnity Claims") for indemnity arising other than pursuant to Tax Indemnification Claims and one-sixth (the "Tax Indemnity Shares") shall be available only with respect to satisfaction of Tax Indemnification Claims. The shares of Parent Common Stock represented by the stock certificates so delivered by the Stockholders to the Escrow Agent are herein referred to in the aggregate as the "Escrow Fund." The Escrow Agent shall maintain a separate account for each Stockholder's, and, subsequent to any transfer permitted pursuant to Paragraph 1(e) hereof, each Owner's, portion of the Escrow Fund, separately designated as to Basic Indemnity Shares and Tax Indemnity Shares. (b) The Escrow Agent hereby agrees to act as escrow agent and to hold, safeguard and disburse the Escrow Fund pursuant to the terms and conditions hereof. It shall treat the Escrow Fund as a trust fund in accordance with the terms of this Agreement and not as the property of Parent. The Escrow Agent's duties hereunder shall terminate upon its distribution of the entire Escrow Fund in accordance with this Agreement. (c) Except as herein provided, the Owners shall retain all of their rights as stockholders of Parent with respect to shares of Parent Common Stock constituting the Escrow Fund during the period the Escrow Fund is held by the Escrow Agent (the "Escrow Period"), including, without limitation, the right to vote their shares of Parent Common Stock included in the Escrow Fund. (d) During the Escrow Period, all dividends payable in cash with respect to the shares of Parent Common Stock included in the Escrow Fund shall be paid to the Owners, but all dividends payable in stock or other non-cash property ("Non-Cash Dividends") shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term "Escrow Fund" shall be deemed to include the Non-Cash Dividends distributed thereon, if any. (e) During the Escrow Period, no sale, transfer or other disposition may be made of any or all of the shares of Parent Common Stock in the Escrow Fund except (i) to a "Permitted Transferee" (as hereinafter defined), (ii) by virtue of the laws of descent and distribution upon death of any Owner, or (iii) pursuant to a qualified domestic relations order; provided, however, that such permissive transfers may be implemented only upon the respective transferee's written agreement to be bound by the terms and conditions of this Agreement. As used in this Agreement, the term "Permitted Transferee" shall include: (x) members of a Stockholder's "Immediate Family" (as hereinafter defined); (y) an entity in which (A) a Stockholder and/or members of a Stockholder's Immediate Family beneficially own 100% of such entity's voting and non-voting equity securities, or (B) a Stockholder and/or a member of such Stockholder's Immediate Family is a general partner and in which such Stockholder and/or members of such Stockholder's Immediate Family beneficially own 100% of all capital accounts of such entity; and (z) a revocable trust established by a Stockholder during his lifetime for the benefit of such Stockholder or for the exclusive benefit of all or any of such Stockholder's Immediate Family. As used in this Agreement, the term "Immediate Family" means, with respect to any Stockholder, a spouse, parents, lineal descendants, the spouse of any lineal descendant, and brothers and sisters (or a trust, all of whose current beneficiaries are members of an Immediate Family of the Stockholder). In connection with and as a condition to each permitted transfer, the Permitted Transferee shall deliver to the Escrow Agent an assignment separate from certificate executed by the transferring Stockholder, with medallion signature guaranty, or where applicable, an order of a court of competent jurisdiction, evidencing the transfer of shares to the Permitted Transferee, together with two (2) assignments separate from certificate executed in blank by the Permitted Transferee, with medallion signature guaranties, with respect to the shares transferred to the Permitted Transferee. Upon receipt of such documents, the Escrow Agent shall deliver to Parent's transfer agent the original stock certificate out of which the assigned shares are to be transferred, together with the executed assignment separate from certificate executed by the transferring Stockholder, or a copy of the applicable court order, and shall request that Parent issue new certificates representing (m) the number of shares, if any, that continue to be owned by the transferring Stockholder, and (n) the number of shares owned by the Permitted 2 Transferee as the result of such transfer. Parent, the transferring Stockholder and the Permitted Transferee shall cooperate in all respects with the Escrow Agent in documenting each such transfer and in effectuating the result intended to be accomplished thereby. During the Escrow Period, no Owner shall pledge or grant a security interest in such Owner's shares of Parent Common Stock included in the Escrow Fund or grant a security interest in such Owner's rights under this Agreement. 2. (a) Parent, acting through the current or former member or members of Parent's Board of Directors who has or have been appointed by Parent to take all necessary actions and make all decisions on behalf of Parent with respect to its and Target's rights to indemnification under Article VII of the Merger Agreement (the "Committee"), may make a claim for indemnification pursuant to the Merger Agreement ("Indemnity Claim") against the Escrow Fund by giving notice (a "Notice") to the Representative (with a copy to the Escrow Agent) specifying (i) the covenant, representation, warranty, agreement, undertaking or obligation contained in the Merger Agreement which it asserts has been breached or otherwise entitles Parent or Target to indemnification, (ii) in reasonable detail, the nature and dollar amount of any Indemnity Claim, (iii) whether the Indemnity Claim is a Basic Indemnity Claim or a Tax Indemnity Claim, and (iv) whether the Indemnity Claim results from a Third Party Claim against Parent or Target. The Committee also shall deliver to the Escrow Agent (with a copy to the Representative), concurrently with its delivery to the Escrow Agent of the Notice, a certification as to the date on which the Notice was delivered to the Representative. (b) If the Representative shall give a notice to the Committee (with a copy to the Escrow Agent) (a "Counter Notice"), within 30 days following the date of receipt (as specified in the Committee's certification) by the Representative of a copy of the Notice, disputing whether the Indemnity Claim is indemnifiable under the Merger Agreement, the Committee and the Representative shall attempt to resolve such dispute by voluntary settlement as provided in paragraph 2(c) below. If no Counter Notice with respect to an Indemnity Claim is received by the Escrow Agent from the Representative within such 30-day period, the Indemnity Claim shall be deemed to be an Established Claim (as hereinafter defined) for purposes of this Agreement. (c) If the Representative delivers a Counter Notice to the Escrow Agent, the Committee and the Representative shall, during the period of 60 days following the delivery of such Counter Notice or such greater period of time as the parties may agree to in writing (with a copy to the Escrow Agent), attempt to resolve the dispute with respect to which the Counter Notice was given. If the Committee and the Representative shall reach a settlement with respect to any such dispute, they shall jointly deliver written notice of such settlement to the Escrow Agent specifying the terms thereof. If the Committee and the Representative shall be unable to reach a settlement with respect to a dispute, such dispute shall be resolved by arbitration pursuant to paragraph 2(d) below. (d) If the Committee and the Representative cannot resolve a dispute prior to expiration of the 60-day period referred to in paragraph 2(c) above (or such longer period as the parties may have agreed to in writing), then such dispute shall be 3 submitted (and either party may submit such dispute) for arbitration before a single arbitrator in New York, New York, in accordance with the commercial arbitration rules of the American Arbitration Association then in effect and the provisions of Section 10.12 of the Merger Agreement to the extent that such provisions do not conflict with the provisions of this paragraph. The Committee and the Representative shall attempt to agree upon an arbitrator; if they shall be unable to agree upon an arbitrator within 10 days after the dispute is submitted for arbitration, then either the Committee or the Representative, upon written notice to the other, may apply for appointment of such arbitrator by the American Arbitration Association. Each party shall pay the fees and expenses of counsel used by it and 50% of the fees and expenses of the arbitrator and of other expenses of the arbitration. The arbitrator shall render his decision within 90 days after his appointment and may award costs to either the Committee or the Representative if, in his sole opinion reasonably exercised, the claims made by any other party had no reasonable basis and were arbitrary and capricious. Such decision and award shall be in writing and shall be final and conclusive on the parties, and counterpart copies thereof shall be delivered to each of the parties. Judgment may be obtained on the decision of the arbitrator so rendered in any federal or state court sitting in New York County, New York, having jurisdiction, and may be enforced in accordance with the law of the State of New York. If the arbitrator shall fail to render his decision or award within such 90-day period, either the Committee or the Representative may apply to any federal or state court sitting in New York County, New York, then having jurisdiction, by action, proceeding or otherwise, as may be proper to determine the matter in dispute consistently with the provisions of this Agreement. The parties consent to the exclusive jurisdiction of the federal and state courts sitting in New York County, New York, for this purpose. The prevailing party (or either party, in the case of a decision or award rendered in part for each party) shall send a copy of the arbitration decision or of any judgment of the court to the Escrow Agent. (e) As used in this Agreement, "Established Claim" means any (i) Indemnification Claim deemed established pursuant to the last sentence of paragraph 2(b) above, (ii) Indemnification Claim resolved in favor of Parent or Target by settlement pursuant to paragraph 2(c) above, resulting in a dollar award to Parent or Target, (iii) Indemnification Claim established by the decision of an arbitrator pursuant to paragraph 2(d) above, resulting in a dollar award to Parent, (iv) Third Party Claim that has been sustained by a final determination (after exhaustion of any appeals) of a court of competent jurisdiction, or (v) Third Party Claim that the Committee and the Representative have jointly notified the Escrow Agent has been settled in accordance with the provisions of the Merger Agreement. (f) (i) Promptly after an Indemnity Claim becomes an Established Claim, the Committee and the Representative shall jointly deliver a notice to the Escrow Agent (a "Joint Notice") directing the Escrow Agent to pay to Parent, and the Escrow Agent promptly shall pay to Parent, an amount equal to the aggregate dollar amount of the Established Claim (or, if at such time there remains in the Escrow Fund less than the full amount so payable, the full amount remaining in the Escrow Fund). 4 (ii) Payment of an Established Claim shall be made in shares of Parent Common Stock that are either Basic Indemnity Shares or Tax Indemnity Shares, as the case may be, pro rata from the account maintained on behalf of each Owner. For purposes of each payment, such shares shall be valued at the "Fair Market Value" (as defined below). However, in no event shall the Escrow Agent be required to calculate Fair Market Value or make a determination of the number of shares to be delivered to Parent in satisfaction of any Established Claim; rather, such calculation shall be included in and made part of the Joint Notice. The Escrow Agent shall transfer to Parent out of the Escrow Fund that number of shares of Parent Common Stock necessary to satisfy each Established Claim, as set out in the Joint Notice. Any dispute between the Committee and the Representative concerning the calculation of Fair Market Value or the number of shares necessary to satisfy any Established Claim, or any other dispute regarding a Joint Notice, shall be resolved between the Committee and the Representative in accordance with the procedures specified in paragraph 2(d) above, and shall not involve the Escrow Agent. Each transfer of shares in satisfaction of an Established Claim shall be made by the Escrow Agent delivering to Parent one or more stock certificates held in each Owner's account evidencing not less than such Owner's pro rata portion of the aggregate number of shares specified in the Joint Notice, together with assignments separate from certificate executed in blank by such Owner and completed by the Escrow Agent in accordance with instructions included in the Joint Notice. Upon receipt of the stock certificates and assignments, Parent shall deliver to the Escrow Agent new certificates representing the number of shares owned by each Owner after such payment. The parties hereto (other than the Escrow Agent) agree that the foregoing right to make payments of Established Claims in shares of Parent Common Stock may be made notwithstanding any other agreements restricting or limiting the ability of any Owner to sell any shares of Parent stock or otherwise. The Committee and the Representative shall be required to exercise utmost good faith in all matters relating to the preparation and delivery of each Joint Notice. As used herein, "Fair Market Value" means the average reported closing price for the Parent Common Stock for the ten trading days ending on the last trading day prior to the day the Established Claim is paid. (iii) Notwithstanding anything herein to the contrary, at such time as an Indemnification Claim has become an Established Claim, the Representative shall have the right to substitute for the Escrow Shares that otherwise would be paid in satisfaction of such claim (the "Claim Shares"), cash in an amount equal to the Fair Market Value of the Claim Shares ("Substituted Cash"). In such event (i) the Joint Notice shall include a statement describing the substitution of Substituted Cash for the Claim Shares, and (ii) substantially contemporaneously with the delivery of such Joint Notice, the Representative shall cause currently available funds to be delivered to the Escrow Agent in an amount equal to the Substituted Cash. Upon receipt of such Joint Notice and Substituted Cash, the Escrow Agent shall (y) in payment of the Established Claim described in the Joint Notice, deliver the Substituted Cash to Parent in lieu of the Claim Shares, and (z) cause the Claim Shares to be returned to the Representative. 3. On the first Business Day after the Escrow Termination Date, upon receipt of a Joint Notice, the Escrow Agent shall distribute and deliver to each Owner certificates representing the shares of Parent Common Stock then in such Owner's 5 account in the Escrow Fund that are Basic Indemnity Shares, unless at such time there are any Basic Indemnity Claims with respect to which Notices have been received but which have not been resolved pursuant to Section 2 hereof or in respect of which the Escrow Agent has not been notified of, and received a copy of, a final determination (after exhaustion of any appeals) by a court of competent jurisdiction, as the case may be (in either case, "Pending Claims"), and which, if resolved or finally determined in favor of Parent, would result in a payment to Parent, in which case the Escrow Agent shall retain, and the total amount of such distributions to such Owner shall be reduced by, the "Pending Claims Reserve" (as hereafter defined). The Committee shall certify to the Escrow Agent the Fair Market Value to be used in calculating the Pending Claims Reserve and the number of shares of Parent Common Stock to be retained therefor. Thereafter, if any Pending Claim becomes an Established Claim, the Committee and the Representative shall deliver to the Escrow Agent a Joint Notice directing the Escrow Agent to pay to Parent an amount in respect thereof determined in accordance with paragraph 2(f) above, and to deliver to each Owner shares of Parent Common Stock then in such owner's account in the Escrow Fund having a Fair Market Value equal to the amount by which the remaining portion of his account in the Escrow Fund exceeds the then Pending Claims Reserve (determined as set forth below), all as specified in a Joint Notice. If any Pending Claim is resolved against Parent, the Committee and the Representative shall deliver to the Escrow Agent a Joint Notice directing the Escrow Agent to pay to each Owner the amount by which the remaining portion of his account in the Escrow Fund exceeds the then Pending Claims Reserve. Upon resolution of all Pending Claims, the Committee and the Representative shall deliver to the Escrow Agent a Joint Notice directing the Escrow Agent shall pay to such Owner the remaining portion of his or her account in the Escrow Fund. On the first Business Day after the Tax Escrow Termination Date, upon receipt of a Joint Notice, the Escrow Agent shall distribute and deliver to each Owner certificates representing the shares of Parent Common Stock then in such Owner's account in the Escrow Fund that are Tax Indemnity Shares and any remaining Basic Indemnity Shares, regardless of whether or not such Basic Indemnity Shares are part of the Pending Claims Reserve. As used herein, the "Pending Claims Reserve" shall mean, at the time any such determination is made, that number of shares of Parent Common Stock in the Escrow Fund having a Fair Market Value equal to the sum of the aggregate dollar amounts claimed to be due with respect to all Pending Claims (as shown in the Notices of such Claims). 4. The Escrow Agent, the Committee and the Representative shall cooperate in all respects with one another in the calculation of any amounts determined to be payable to Parent and the Owners in accordance with this Agreement and in implementing the procedures necessary to effect such payments. 5. (a) The Escrow Agent undertakes to perform only such duties as are expressly set forth herein. It is understood that the Escrow Agent is not a trustee or fiduciary and is acting hereunder merely in a ministerial capacity. 6 (b) The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and in the exercise of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Escrow Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which is believed by the Escrow Agent to be genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto. (c) The Escrow Agent's sole responsibility upon receipt of any notice requiring any payment to Parent pursuant to the terms of this Agreement or, if such notice is disputed by the Committee or the Representative, the settlement with respect to any such dispute, whether by virtue of joint resolution, arbitration or determination of a court of competent jurisdiction, is to pay to Parent the amount specified in such notice, and the Escrow Agent shall have no duty to determine the validity, authenticity or enforceability of any specification or certification made in such notice. (d) The Escrow Agent shall not be liable for any action taken by it in good faith and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement, and may consult with counsel of its own choice and shall have full and complete authorization and indemnification under Section 5(g), below, for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel. (e) The Escrow Agent may resign at any time and be discharged from its duties as escrow agent hereunder by its giving the other parties hereto written notice and such resignation shall become effective as hereinafter provided. Such resignation shall become effective at such time that the Escrow Agent shall turn over the Escrow Fund to a successor escrow agent appointed jointly by the Committee and the Representative. If no new escrow agent is so appointed within the 60 day period following the giving of such notice of resignation, the Escrow Agent may deposit the Escrow Fund with any court it reasonably deems appropriate. (f) In the event of a dispute between the parties as to the proper disposition of the Escrow Fund, the Escrow Agent shall be entitled (but not required) to deliver the Escrow Fund into the United States District Court for the Southern District of New York and, upon giving notice to the Committee and the Representative of such action, shall thereupon be relieved of all further responsibility and liability. (g) The Escrow Agent shall be indemnified and held harmless by Parent from and against any expenses, including counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with any action, suit or other proceeding 7 involving any claim which in any way, directly or indirectly, arises out of or relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Fund held by it hereunder, other than expenses or losses arising from the gross negligence or willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or disposition of the Escrow Fund or it may deposit the Escrow Fund with the clerk of any appropriate court and be relieved of any liability with respect thereto or it may retain the Escrow Fund pending receipt of a final, non-appealable order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Escrow Fund are to be disbursed and delivered. (h) The Escrow Agent shall be entitled to reasonable compensation from Parent for all services rendered by it hereunder. The Escrow Agent shall also be entitled to reimbursement from Parent for all expenses paid or incurred by it in the administration of its duties hereunder including, but not limited to, all counsel, advisors' and agents' fees and disbursements and all taxes or other governmental charges. (i) From time to time on and after the date hereof, the Committee and the Representative shall deliver or cause to be delivered to the Escrow Agent such further documents and instruments and shall do or cause to be done such further acts as the Escrow Agent shall reasonably request to carry out more effectively the provisions and purposes of this Agreement, to evidence compliance herewith or to assure itself that it is protected in acting hereunder. (j) Notwithstanding anything herein to the contrary, the Escrow Agent shall not be relieved from liability hereunder for its own gross negligence or its own willful misconduct. 6. This Agreement expressly sets forth all the duties of the Escrow Agent with respect to any and all matters pertinent hereto. No implied duties or obligations shall be read into this Agreement against the Escrow Agent. The Escrow Agent shall not be bound by the provisions of any agreement among the parties hereto except this Agreement and shall have no duty to inquire into the terms and conditions of any agreement made or entered into in connection with this Agreement, including, without limitation, the Merger Agreement. 7. This Agreement shall inure to the benefit of and be binding upon the parties and their respective heirs, successors, assigns and legal representatives, shall be governed by and construed in accordance with the law of Delaware applicable to contracts made and to be performed therein except that issues relating to the rights and obligations of the Escrow Agent shall be governed by and construed in accordance with the law of New York applicable to contracts made and to be performed therein. This Agreement cannot be changed or terminated except by a writing signed by the Committee, the Representative and the Escrow Agent. 8 8.
