FOR IMMEDIATE RELEASE

ARPEGGIO ACQUISITION CORPORATION AND HILL INTERNATIONAL, INC.

ANNOUNCE HILL’S FINANCIAL RESULTS FOR FISCAL YEAR 2005

Marlton, NJ and New York, NY – April 10, 2006 – Arpeggio Acquisition Corporation (OTCBB: APGO, APGOW, APGOU) (“Arpeggio”), a special purpose acquisition company, and Hill International, Inc. (“Hill”), a worldwide construction consulting firm, have jointly announced the filing of Arpeggio’s amended proxy statement with the Securities and Exchange Commission (“SEC”) earlier today. The filing includes, among other items, audited financial results for Hill for the fiscal years ended December 31, 2005 and January 1, 2005. As previously announced, Arpeggio and Hill have entered into a merger agreement pursuant to which Hill will merge with and into Arpeggio.

For the year ended December 31, 2005, Hill achieved record revenue of $112.2 million as compared to $84.1 million in the prior year, an increase of 33.4%. Hill’s net revenue (defined as revenue less reimbursable expenses) in 2005 totaled $80.1 million, also a record for the company, as compared with $63.0 million in 2004, an increase of 27.1%. The increase in net revenue is primarily related to higher revenue overseas in the company’s Project Management Group.

Gross profit increased to $36.8 million in 2005 from $28.7 million in 2004, an increase of 28.5%. Gross profit as a percentage of net revenue was 46.0% in 2005, a slight increase from 45.5% in 2004.

In 2005, Hill’s selling, general and administrative (SG&A) expense increased slightly to $31.9 million from $29.2 million in the prior year, but decreased as a percentage of net revenue to 39.8% from 46.4% in the prior year. Of Hill’s 2005 SG&A expense, $1.2 million was related to a compensation charge due to the adoption of SFAS 123(R) in connection with Hill’s employee stock option plan, and $0.7 million was related to certain litigation matters, with respect to which Arpeggio is entitled to indemnification under the parties’ merger agreement.

Operating income in 2005 was $5.7 million, versus a loss of $0.1 million in the prior year, principally due to higher net revenue and gross profit, offset by SG&A expense that grew at a significantly slower rate. Hill’s net income in 2005 was $3.1 million versus a loss in 2004 of $0.4 million, which included in selling, general and administrative expenses $1.2 million of pretax nonrecurring items related to litigation and restructuring.
