ABOUT HILL INTERNATIONAL, INC.

We provide fee-based project management and construction claims services to clients worldwide, but primarily in the United States, Europe, the Middle East/North Africa and Asia/Pacific. Our clients include the United States and other national governments and their agencies, state and local governments and their agencies and the private sector. Our company was incorporated in Delaware in 2004, under the name Arpeggio Acquisition Corporation, as a specified purpose acquisition corporation. On June 28, 2006, we merged with Hill International, Inc., a Delaware corporation, and our company was the surviving entity of the merger. Following the merger, we changed the name of our company to Hill International, Inc. We are organized into two key operating segments: the Project Management Group and the Construction Claims Group.

In our Project Management Group, we provide construction management services which include program management, project management, construction management, project management oversight, troubled project turnaround, staff augmentation, estimating and cost management, project labor agreements and management consulting. In our Construction Claims Group, we advise clients in order to assist them in preventing or resolving claims and disputes based upon schedule delays, cost overruns and other problems on major construction projects worldwide.

Our executive and operating offices are located at 303 Lippincott Centre, Marlton, New Jersey 08053. The telephone number at our executive office is (856) 810-6200. We maintain a website at www.hillintl.com. The information contained on our website is not a part of, and is not incorporated by reference into, this prospectus.

RISK FACTORS

You should carefully consider the following risk factors, together with all of the other information included in this report in evaluating your investment in Hill securities and any investment you decide to make in the common stock of Hill.

The value of your investment in Hill is subject to the significant risks inherent in the construction management and claims consulting business. You should carefully consider the risks and uncertainties described below and other information included in this report. If any of the events described below occur, our business and financial results could be adversely affected in a material way. This could cause the trading price of our equity securities to decline, perhaps significantly, and you therefore may lose all or part of your investment.

We depend on long-term government contracts, many of which are funded on an annual basis. If appropriations are not made in subsequent years of a multiple-year contract, we will not realize all of our potential revenue and profit from that project.

A majority of our revenues is derived from contracts with agencies and departments of federal, state, local and foreign governments. During our 2007, 2006 and 2005 fiscal years, approximately 54.0%, 54.7% and 69.2%, respectively, of our total revenues were derived from contracts with government agencies and authorities.

Most government contracts are subject to the continuing availability of legislative appropriation. Legislatures typically appropriate funds for a given program on a year-by-year basis, even though contract performance may take more than one year. As a result, at the beginning of a program, the related contract is only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent fiscal year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by, among other things, the state of the economy, competing priorities for appropriation, the timing and amount of tax receipts and the overall level of government expenditures. If appropriations are not made in subsequent years on government contracts, then we will not realize all of our potential revenue and profit from those contracts.

Because we depend on government contracts for a significant portion of our revenue, our inability to win profitable government contracts could harm our operations and adversely affect our net income.

Total revenues from U.S. federal government contracts and from state and local government contracts represented approximately 11.7% and 29.2%, respectively, of our total revenues during fiscal year 2007 and revenues from foreign government contracts represented approximately 13.1% of such annual revenues. Our inability to win profitable government contracts could harm our operations and adversely affect our net income. Government contracts are typically awarded through a heavily regulated procurement process. Some government contracts are awarded to multiple competitors, causing increases in overall competition and pricing pressure. The competition and pricing pressure, in turn, may require us to make sustained post-award efforts to reduce costs under these contracts. If we are not successful in reducing the amount of costs we anticipate, our profitability on these contracts may be negatively impacted. Also, some of our federal government contracts require U.S. government security clearances. If we or certain of our personnel were to lose these security clearances, our ability to continue performance of these contracts or to win new contracts requiring a clearance may be negatively impacted.

We depend on contracts that may be terminated by our clients on short notice, which may affect our ability to recognize all of our potential revenue and profit from the project.

Substantially all of our contracts are subject to termination by the client either at its convenience or upon our default. If one of our clients terminates a contract at its convenience, then we typically are able to recover only costs incurred or committed, settlement expenses and profit on work completed prior to termination, which could prevent us from recognizing all of our potential revenue and profit from that contract. If one of our clients terminates the contract due to our default, we could be liable for excess costs incurred by the client in re-procuring services from another source, as well as other costs.

Our contracts with governmental agencies are subject to audit, which could result in adjustments to reimbursable contract costs or, if we are charged with wrongdoing, possible temporary or permanent suspension from participating in government programs.

Our books and records are subject to audit by the various governmental agencies we serve and by their representatives. These audits can result in adjustments to reimbursable contract costs and allocated overhead. In addition, if as a result of an audit, we or one of our subsidiaries is charged with wrongdoing or the government agency determines that we or one of our subsidiaries is otherwise no longer eligible for federal contracts, then we or, as applicable, that subsidiary, could be temporarily suspended or, in the event of convictions or civil judgments, could be prohibited from bidding on and receiving future government contracts for a period of time. Furthermore, as a U.S. government contractor, we are subject to an increased risk of investigations, criminal prosecution, civil fraud, whistleblower lawsuits and other legal actions and liabilities to which non-government contractors are not, the results of which could have a material adverse effect on our operations.

We submit change orders to our customers for work we perform beyond the scope of some of our contracts. If our customers do not approve these change orders, our net income and results of operations could be adversely impacted.

We typically submit change orders under some of our contracts for payment for work performed beyond the initial contractual requirements. The clients may not approve or may contest these change orders and we cannot assure you that these claims will be approved in whole, in part or at all. If these claims are not approved, our net income and results of operations could be adversely impacted.

Our backlog of uncompleted projects under contract or awarded is subject to unexpected adjustments and cancellations, including future appropriations by the applicable contracting government agency, and is, therefore, an uncertain indicator of our future revenues and profits.

At December 31, 2007, our backlog of uncompleted projects under contract or awarded was approximately $416,000,000. We cannot assure you that the revenues attributed to uncompleted projects under contract will be realized or, if realized, will result in profits.

Many projects may remain in our backlog for an extended period of time because of the size or long-term nature of the contract. In addition, from time to time projects are scaled back or cancelled. These types of backlog reductions adversely affect the revenue and profit that we ultimately receive from contracts reflected in our backlog. Included in our backlog is the maximum amount of all indefinite delivery/indefinite quantity ("ID/IQ"), or task order, contracts, or a lesser amount if we do not reasonably expect to be issued task orders for the maximum amount of such contracts. We cannot provide any assurance that we will in fact be awarded the maximum amount of such contracts.

We depend on the continued services of certain executive officers. We can not assure you that we will be able to retain the services of these individuals.

We are dependent upon the efforts and service of certain executive officers, particularly Irvin E. Richter, our Chairman and Chief Executive Officer, and David L. Richter, our President and Chief Operating Officer, because of their knowledge, experience, skills and relationships with major clients and other members of our management team. Irvin E. Richter has served as our Chief Executive Officer since 1976. We have employment agreements with these individuals which contain non-competition covenants which survive their actual term of employment. We also maintain key-man life insurance coverage for Irvin E. Richter. Nevertheless, if we lost the services of one or both of these individuals for any reason, that could have an adverse effect on our operations.

Our ability to grow and compete in our industry will be harmed if we do not retain the continued service of our key management, sales and technical personnel and identify, hire and retain additional qualified personnel.

There is intense competition for qualified management, sales and technical personnel in the industry sectors in which we compete. We may not be able to continue to attract and retain qualified personnel who are necessary for the development of our business or to replace qualified personnel. Any growth we experience is expected to place increased demands on our resources and will likely require the addition of personnel and the development of additional expertise by existing personnel. Also, some of our personnel hold security clearance levels required to obtain government projects and, if we were to lose some or all of these personnel, they may be difficult to replace. Loss of the services of, or failure to recruit, key personnel could limit our ability to complete existing projects successfully and to compete for new projects.

Our dependence on subcontractors, partners and specialists could adversely affect our business.

We rely on third-party subcontractors as well as third-party strategic partners and specialists to complete our projects. To the extent that we cannot engage such subcontractors, partners or specialists or cannot engage them on a competitive basis, our ability to complete a project in a timely fashion or at a profit may be impaired. If we are unable to engage appropriate strategic partners or specialists in some instances, we could lose the ability to win some contracts. In addition, if a subcontractor or specialist is unable to deliver its services according to the negotiated terms for any reason, including the deterioration of its financial condition or over-commitment of its resources, we may be required to purchase the services from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the services were needed.

If our partners fail to perform their contractual obligations on a project, we could be exposed to legal liability, loss of reputation or reduced profits.

We sometimes enter into joint venture agreements and other contractual arrangements with outside partners to jointly bid on and execute a particular project. The success of these joint projects depends on the satisfactory performance of the contractual obligations of our partners. If any of our partners fails to satisfactorily perform its contractual obligations, we may be required to make additional investments and provide additional services to complete the project. If we are unable to adequately address our partner's performance issues, then our client could terminate the joint project, exposing us to legal liability, loss of reputation or reduced profits.

Our services expose us to significant risks of liability and our insurance policies may not provide adequate coverage.

Our services involve significant risks of professional and other liabilities that may substantially exceed the fees that we derive from our services. In addition, we sometimes contractually assume liability under indemnification agreements. We cannot predict the magnitude of potential liabilities from the operation of our business.

We currently maintain comprehensive general liability, umbrella and professional liability insurance policies. Professional liability policies are "claims made" policies. Thus, only claims made during the term of the policy are covered. Additionally, our insurance policies may not protect us against potential liability due to various exclusions and retentions. Partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse affect on our business.

International operations expose us to legal, political and economic risks in different countries and currency exchange rate fluctuations could adversely affect our financial results.

Revenues attributable to our international operations comprised 58.1%, 52.6% and 37.4% of our total revenues for the 2007, 2006 and 2005 fiscal years, respectively. We expect the percentage of revenues attributable to our international operations to continue to increase. There are risks inherent in doing business internationally, including:

lack of developed legal systems to enforce contractual rights;

greater risk of uncollectible accounts and longer collection cycles;

currency exchange rate fluctuations;

imposition of governmental controls;

political and economic instability;

changes in U.S. and other national government policies affecting the markets for our services;

changes in regulatory practices, tariffs and taxes;

potential non-compliance with a wide variety of non-U.S. laws and regulations; and

general economic and political conditions in these foreign markets.

Any of these factors could have a material adverse effect on our business, results of operations or financial condition.

Changes to the laws of the foreign countries in which we operate may adversely affect our international operations.

We have contracts to perform services for projects located in a number of foreign countries, including, among others Canada, Mexico, the United Kingdom, Spain, Germany, Romania, Macedonia, Serbia, Croatia, Latvia, Greece, Turkey, Georgia, Azerbaijan, Egypt, Libya, Iraq, Kuwait, Bahrain, Qatar, Saudi Arabia, the United Arab Emirates, China, Singapore, Malaysia, Vietnam, South Korea and Australia. We expect to have additional similar contracts in the future. In addition, we have offices or operations in over 25 foreign countries. The laws and regulations in the countries in which we are working on projects or in which we have offices might change. Such changes could have a material adverse effect on our business.

Our business sometimes requires our employees to travel to and work in high security risk countries, which may result in employee injury, repatriation costs or other unforeseen costs.

Many of our employees often travel to and work in high security risk countries around the world that are undergoing or that may undergo political, social and economic upheavals resulting in war, civil unrest, criminal activity or acts of terrorism. For example, we have employees working in Iraq, a high security risk country with substantial civil unrest and acts of terrorism. As a result, we may be subject to costs related to employee injury, repatriation or other unforeseen circumstances.

We have acquired and may continue to acquire businesses as strategic opportunities arise and may be unable to realize the anticipated benefits of those acquisitions.

Since 1998, we have acquired 11 businesses and our strategy is to continue to expand and diversify our operations with additional acquisitions as strategic opportunities arise. Some of the risks that may affect our ability to realize any anticipated benefits from businesses that we acquire include:

unexpected losses of key personnel or clients of the acquired business;

difficulties arising from the increasing scope, geographic diversity and complexity of our operations;

diversion of management's attention from other business concerns; and

adverse effects on existing business relationships with clients.

In addition, managing the growth of our operations will require us to continually increase and improve our operational, financial and human resources management and our internal systems and controls. If we are unable to manage any growth effectively or to successfully integrate any acquisitions, that could have a material adverse effect on our business.

We cannot be certain that we will be able to raise capital or obtain debt financing to execute future acquisitions or to meet required capital needs.

We are currently party to a revolving credit agreement to assist in funding working capital needs and for potential future acquisitions. This agreement contains certain covenants with respect to minimum net worth, total debt to EBITDA ratios, fixed charge coverage ratios, billed accounts receivable to total debt ratios as well as other financial covenants. If our operating results are not as positive as we expect, that could cause us to be in default of these covenants. In addition, our current revolving credit agreement may not provide us with sufficient credit to meet all of the future financial needs of our business. There is no guarantee that we could increase the availability under our current revolving credit agreement or obtain alternative debt or equity financing on terms that would be acceptable to us, or at all.

The market price for our common stock could be volatile and could decline, resulting in a substantial or complete loss of your investment.

The stock markets, including the New York Stock Exchange on which we list our common stock, have experienced significant price and volume fluctuations. As a result, the market price of our common stock could be similarly volatile, and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. The price of our common stock could be subject to wide fluctuations in response to a number of factors, including:

our operating performance and the performance of other similar companies;

actual or anticipated differences in our operating results;

changes in our revenues or earnings estimates or recommendations by securities analysts;

publication of research reports about us or our industry by securities analysts;

additions and departures of key personnel;

speculation in the press or investment community;

actions by institutional shareholders;

changes in accounting principles;

terrorist acts; and

general market conditions, including factors unrelated to our performance.

Future sales of our common stock may depress the price of our common stock.

As of April 10, 2008, there were 40,790,422 shares of our common stock outstanding. We are registering for re-sale to the public 18,493,925 shares of our common stock, which represents approximately 45% of all of our shares outstanding and approximately 86% of our outstanding shares which are held by non-affiliates, in the registration statement of which this prospectus is a part. An additional 948,000 shares of our common stock may be issued upon the exercise of options held by employees, management and directors. An additional 1,000,000 shares may be issued in early 2009, and an additional 1,000,000 shares may be issued in 2010 in connection with earnout provisions of the merger agreement with Arpeggio. Sales of a substantial number of these shares in the public market could decrease the market price of our common stock. In addition, the perception that such sales might occur may cause the market price of our common stock to decline. Future issuances or sales of our common stock could have an adverse effect on the market price of our common stock.

USE OF PROCEEDS

The Company will not receive any proceeds from the sale of the common stock covered by this prospectus.

DIVIDEND POLICY

We currently intend to retain all of our earnings to finance our operations, repay any outstanding indebtedness and fund our future growth. We have not paid any dividends in the past and do not expect to pay any dividends on our common stock for the foreseeable future.

DESCRIPTION OF SECURITIES

The description of the securities covered by this prospectus is contained in our proxy statement filed with the SEC on June 6, 2006, under the heading “Description of Arpeggio Common Stock and Other Securities — Common Stock,” and that description is incorporated herein by reference.

SELLING STOCKHOLDERS

The following table sets forth information with respect to the beneficial ownership of our common stock as of April 10, 2008, by each of the selling stockholders and the maximum number of shares that may be sold hereunder.

We do not know when or in what amounts the selling stockholders will offer shares for sale. The selling stockholders may choose not to sell any or all of the shares offered by this prospectus. We cannot estimate the number of shares that will be sold in the offering or held by the selling stockholders after completion of the offering. Solely for purposes of this table, however, we have assumed that, after completion of the offering, the maximum number of shares covered by this prospectus will have been sold by the selling stockholders. Messrs. I. Richter and D. Richter are directors and executive officers of Hill, and Messrs. Ajdler, Clymer, Doyle, Fellheimer and Rosenfeld are directors of Hill. Messrs. Samelian, Ghali and Emma are executive officers of Hill, and Messrs. S. Richter, Kardous, Ramirez, Pile, Giunta, Palmer, Griffin and Borhan are officers of Hill.

The amounts and percentage of common stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. The inclusion of shares in this table does not constitute an admission of beneficial ownership of all such shares for the stockholders named below. The percentage of our share capital before and after this offering is based on approximately 40.8 million shares of common stock outstanding on April 10, 2008.

The selling stockholders may sell or distribute some or all of their shares from time to time through dealers or brokers or other agents or directly to one or more purchasers in transactions (which may involve crosses and block transactions) on the New York Stock Exchange or other exchanges on which our common stock may be listed for trading, through put or call options transactions relating to the shares, through short sales of shares, in privately negotiated transactions (including sales pursuant to pledges) or in the over-the-counter market, or in brokerage transactions or in a combination of these transactions. In addition, the selling stockholders may sell or distribute some or all of their shares of common stock in a transaction involving an underwriter. Such transactions may be effected by the selling stockholders at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices, which may be changed. Brokers, dealers or their agents participating in such transactions as agent may receive compensation in the form of discounts, concessions or commissions from the selling stockholders (and, if they act as agent for the purchaser of the shares, from the purchaser). Such discounts, concessions or commissions as to a particular broker, dealer or other agent might be in excess of those customary in the type of transaction involved.

If applicable law requires, we will provide a supplement to this prospectus to disclose the specific shares to be sold, the public offering price of the shares to be sold, the names of any agents, dealers or underwriters employed by the selling stockholders in connection with such sale and any applicable commissions or discounts with respect to a particular offer.

If underwriters are used in the sale, the offered securities will be acquired by the underwriters for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to certain conditions. Unless indicated in an accompanying prospectus supplement, the underwriters must purchase all the securities offered if any of the securities are purchased.

The selling stockholders and any such brokers, dealers or other agents that participate in such distribution may be deemed to be “underwriters” within the meaning of the Securities Act of 1933 (the “Securities Act”), and any discounts, commissions or concessions received by any such brokers, dealers or other agents might be deemed to be underwriting discounts and commissions under the Securities Act. Any underwriters or agents will be identified and their compensation described in an accompanying prospectus supplement.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the underwriters, dealers or agents may be required to make.

In connection with the offer and sale of the shares of common stock by the selling stockholders, various state securities laws and regulations require that any such offer and sale should be made only through the use of a broker-dealer registered as such in any state where a selling stockholder engages such broker-dealer and in any state where such broker-dealer intends to offer and sell shares.

Under applicable rules and regulations under the Exchange Act, any person engaged in a distribution of the shares of common stock offered hereby may not simultaneously engage in market activities with respect to common stock for the applicable period under Regulation M prior to the commencement of such distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Rule 10b-5 and Regulation M, which provisions may limit the timing of purchases and sale of any of the shares by the selling stockholders. All of the foregoing may affect the marketability of the shares offered hereby.

We will pay all expenses of the registration of the offered securities, including SEC filing fees and expenses of compliance with state securities or “blue sky” laws. The selling stockholders will pay any underwriting discounts and selling commissions. The selling stockholders will be indemnified by us against certain civil liabilities, including certain liabilities under the Securities Act. The selling stockholders will indemnify us against certain civil liabilities, including certain liabilities under the Securities Act.

INDEMNIFICATION

Our certificate of incorporation provides that the Company, to the full extent permitted by Section 145 of the Delaware General Corporation Law, as amended from time to time, shall indemnify all persons whom it may indemnify pursuant thereto. It further provides that expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative, or investigative action, suit or proceeding for which such officer or director may be entitled to indemnification hereunder shall be paid by the Company in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Company as authorized thereby.

Our bylaws provide the Company with the power to indemnify its officers, directors, employees and agents or any person serving at the Company’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise to the fullest extent permitted by Delaware law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

LEGAL MATTERS

The validity of the common stock offered hereby will be passed upon for us by McCarter & English, LLP.
