 Attachment 1 
 EXHIBIT D 
 VOTING AGREEMENT 
 VOTING AGREEMENT, dated as of this      day of [Closing Date] (“Agreement”), among each of the persons listed under the caption “Target Group” on Exhibit A
attached hereto (the “Target Group”), each of the persons listed under the caption “Founders Group” on Exhibit A attached hereto (the “Founders Group”) and Arpeggio Acquisition Corporation, a Delaware corporation
(“Parent”). Each of the Target Group and the Founders Group is sometimes referred to herein as a “Group”. For purposes of this Agreement, each person who is a member of either the Target Group or the Founders Group is referred to
herein individually as a “Stockholder” and collectively as the “Stockholders”. 
 WHEREAS, as of December 5, 2005, each of Parent,
Hill International, Inc. (the “Company”), a Delaware corporation, and the Stockholders who are members of the Target Group have entered into an Agreement and Plan of Merger (the “Merger Agreement”) that provides, inter
alia, upon the terms and subject to the conditions thereof, for the merger of the Company into Parent (the “Merger”); 
 WHEREAS, as of the
date hereof, each Stockholder who is a member of the Founders Group owns beneficially and of record shares of common stock of Parent, par value $0.0001 per share (“Parent Common Stock”), as set forth opposite such Stockholder’s name
on Exhibit A hereto (all such shares and any shares of which ownership of record or the power to vote is hereafter acquired by any of the Stockholders, whether by purchase, conversion or exercise, prior to the termination of this
Agreement being referred to herein as the “Shares”); 
 WHEREAS, at the Effective Time, all shares of Company Common Stock beneficially owned by
each Stockholder who is a member of the Target Group shall be converted into the right to receive and shall be exchanged for his, her or its pro rata portion of the shares of Parent Common Stock to be issued to the Company’s security holders as
consideration in the Merger; 
 WHEREAS, as a condition to the consummation of the Merger Agreement, the Stockholders have agreed, severally, to enter into
this Agreement; and 
 WHEREAS, capitalized terms used but not defined in this Agreement shall have the meanings ascribed to them in the Merger Agreement;

 NOW, THEREFORE, in consideration of the premises and of the mutual agreements and covenants set forth herein and in the Merger Agreement, and intending to
be legally bound hereby, the parties hereto hereby agree as follows: 
 ARTICLE I 
 VOTING OF SHARES FOR DIRECTORS 
 SECTION 1.01 Vote in Favor of the
Directors. During the term of this Agreement, each Stockholder agrees to vote the Shares of Parent Common Stock he, she or it now owns, or will 
  

 9 








 hereafter acquire prior to the termination of this Agreement, for the election and re-election of the following persons
as directors of Parent: 
 (a) Five (5) persons, (i) three of whom shall at all times be “independent
directors,” within the meaning of the Nasdaq rules, and (ii) all of whom shall be designees of the Target Group; with two (2) of such designees to stand for election in 2007 (“Class A Directors”), who shall initially be
Irvin E. Richter and William J. Doyle, of whom Mr. Doyle shall be an “independent director;” two (2) of such designees to stand for election in 2008 (“Class B Directors”), who shall initially be David L. Richter and
Alan S. Fellheimer, of whom Mr. Fellheimer shall be an “independent director,” and one (1) of such designees to stand for election in 2009 (“Class C Directors”), who shall Brian W. Clymer, and who shall be an
“independent director” (collectively, the “Target Directors”); and 
 (b) Two (2) persons, both of
whom shall be designees of the Founders Group, which designees initially shall be Eric S. Rosenfeld, who shall be elected as a Class A Director, and Arnaud Ajdler, who shall be elected as a Class C Director (the “Founders Directors,”
and together with the Target Directors, the “Director Designees”). 
 Neither the Stockholders, nor any of the
officers, directors, stockholders, members, managers, partners, employees or agents of any Stockholder, makes any representation or warranty as to the fitness or competence of any Director Designee to serve on the Board of Directors by virtue of
such party’s execution of this Agreement or by the act of such party in designating or voting for such Director Designee pursuant to this Agreement. 
 Any Director Designee may be removed from the Board of Directors in the manner allowed by law and Parent’s governing documents except that each Stockholder agrees that he, she or it will not, as a stockholder,
vote for the removal of any director who is a member of Group of which such Stockholder is not a member. If a director is removed or resigns from office, the remaining directors of the Group of which the vacating director is a member shall be
entitled to appoint the successor. 
 SECTION 1.02 Vote in Favor of Stock Option Plan. During the term of this Agreement, each
Stockholder agrees to vote the Shares of Parent Common Stock he, she or it now owns, or hereafter acquires prior to the termination of this Agreement, in favor of the adoption of the Parent Plan (as defined in the Merger Agreement). 
 SECTION 1.03 Obligations of Parent. Parent shall take all necessary and desirable actions within its control during the term of this Agreement to
provide for the Parent Board of Directors to be comprised of seven (7) members and to enable the election to the Board of Directors of the Director Designees. 
 SECTION 1.04 Term of Agreement. The obligations of the Stockholders pursuant to this Agreement shall terminate immediately following the election or re-election of directors at the annual meeting of Parent that
will be held in 2007. 
 SECTION 1.05 Obligations as Director and/or Officer. Nothing in this Agreement shall be deemed to limit or
restrict any director or officer of Parent from acting in his or her capacity as such director or officer or from exercising his or her fiduciary duties and responsibilities, it being 
  

 10 








 agreed and understood that this Agreement shall apply to each Stockholder solely in his or her capacity as a stockholder
of Parent and shall not apply to his or her actions, judgments or decisions as a director or officer of Parent if he or she is such a director or officer. 
 SECTION 1.06 Transfer of Shares. If a member of the Target Group desires to transfer his, her or its Shares to a permitted transferee pursuant to the Lock-Up Agreement of even date herewith executed by such
member, or if a member of the Founders Group desires to transfer his or its shares to a permitted transferee pursuant to the Stock Escrow Agreement dated as of June 24, 2004, it shall be a condition to such transfer that the transferee agree to
be bound by the provisions of this Agreement. This Agreement shall in no way restrict the transfer on the public market of Shares that are not subject to the Lock-Up Agreement or the Stock Escrow Agreement, and any such transfers on the public
market of Shares not subject to the provisions of the Lock-Up Agreement or the Stock Escrow Agreement, as applicable, shall be free and clear of the restrictions in this Agreement. 
 ARTICLE II

 COVENANTS OF THE STOCKHOLDERS

legal capacity and authority to enter into this Agreement and to carry out such Stockholder’s obligations hereunder. This Agreement has been duly executed and delivered by such Stockholder, and (assuming due authorization, execution and
delivery by Parent and the other Stockholders) this Agreement constitutes a legal, valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms. 
 SECTION 2.02 No Conflict; Required Filings and Consents. 
 (a) The execution and delivery of this Agreement by such Stockholder does not, and the performance of this Agreement by such Stockholder
will not, (i) conflict with or violate any Legal Requirement applicable to such Stockholder or by which any property or asset of such Stockholder is bound or affected, or (ii) result in any breach of or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or give to others any right of termination, amendment, acceleration or cancellation of, or result in the creation of any encumbrance on any property or asset of such
Stockholder, including, without limitation, the Shares, pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation. 
 (b) The execution and delivery of this Agreement by such Stockholder does not, and the performance of this Agreement by such Stockholder
will not, require any consent, approval, authorization or permit of, or filing with or notification to, any governmental or regulatory authority, domestic or foreign, except (i) for applicable requirements, if any, of the Exchange Act, and
(ii) where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not prevent or materially delay the performance by such Stockholder of such Stockholder’s obligations
under this Agreement.
