PART I

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We make forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995. We use forward-looking words such as may, expect, anticipate, contemplate, believe, estimate,
intends, and continue or similar words. You should read statements that contain these words carefully because they discuss future expectations, contain projections of future results of operations or financial condition or
state other forward-looking information. However, there may be events in the future that we are not able to predict accurately or over which we have no control. Examples of risks, uncertainties and events that may cause actual results to
differ materially from the expectations described by us in such forward-looking statements include those described in Item 1A. Risk Factors of this Form 10-K. You are cautioned not to place undue reliance on these forward-looking
statements, which speak only as of the date of hereof. All forward-looking statements included herein attributable to us are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Except to the
extent required by applicable laws and regulations, we undertake no obligations to update these forward-looking statements.

General

Arpeggio Acquisition Corporation (Arpeggio) was incorporated in Delaware in 2004 as a specified purpose acquisition corporation. On
June 28, 2006, Arpeggio merged with Hill International, Inc. (Old Hill), a Delaware corporation, and Arpeggio was the surviving entity of the merger. Old Hill was founded in 1976 by our current Chairman and Chief Executive Officer,
Irvin E. Richter. Immediately following the merger, the stockholders of Old Hill owned approximately 63.6% of the total voting power of Arpeggio. The merger was accounted for as a reverse acquisition under U.S. generally accepted accounting
principles pursuant to which Old Hill was considered to be the acquiring entity and Arpeggio was the acquired company for accounting purposes, accompanied by a recapitalization of Old Hill. Accordingly, the historical financial statements relate to
the business of Old Hill and its consolidated subsidiaries. Following the merger, Arpeggio changed its name to Hill International, Inc. In this report, the terms Company, we, us, our or
Hill refer to 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.

We are one of the leading firms in the world in both the project management and construction claims consulting businesses.
We are a global company with over 1,800 employees operating out of over 70 offices in more than 25 countries.

In addition, we believe
there are high barriers to entry for new competitors especially in the project management market. We compete for business based on reputation and past experience, including client requirements for substantial experience in similar projects and
claims work. We have developed significant long-standing relationships which bring us repeat business and would be very difficult to replicate. We have an excellent reputation for developing and rewarding employees which allows us to attract and
retain superior professionals.

Reporting Segments

We operate through two segments: the Project Management Group and the Construction Claims Group. Reimbursable expenses are reflected in equal amounts in both total revenue and total direct expenses. Because these
revenues/costs are subject to significant fluctuation from year to year, we measure the performance

of many of our key operating metrics as a percentage of consulting fee revenue (CFR), as we believe that this is a better and more consistent
measure of operating performance than total revenue. Throughout this report we have used CFR as the denominator in many of our ratios. The following table sets forth the amount and percentage of our CFR from our operations in each reporting segment
for each of the past three fiscal years:

A description of the business of each segment follows:

Project Management

Our Project Management
Group provides fee-based or agency construction management services to our clients leveraging our construction expertise to identify potential trouble, difficulties and sources of delay on a construction project before they develop into
costly problems. Our services 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.

Our clients are typically billed a negotiated multiplier of the actual direct cost of each consultant assigned to a
project and we are reimbursed for all out-of-pocket expenses. We believe our fee-based consulting has significant advantages over traditional general contractors. Specifically, because we do not assume project completion risk, our fee-based model
eliminates many of the risks typically associated with construction projects.

As construction managers, we have managed all phases of the
construction process on behalf of project owners and developers, from pre-design through completion. Specific activities that we undertake as part of these services include: planning, scheduling, estimating, budgeting, design review,
constructability analyses, value engineering, regulatory compliance, development of project procedures, procurement, project reporting, expediting, inspection, quality assurance/quality control, safety oversight, contract administration, change
order processing, claims management, and on-site management of contractors, subcontractors and suppliers.

In its June 11, 2007,
issue, Engineering News-Record ranked us as the tenth largest construction management firm and the ninth largest program management firm in the United States.

Construction Claims

Our Construction Claims Group advises 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.

We may be retained as a claims consultant at the onset of a project, during the course of a project or upon the completion of a project. We also assist owners or contractors in adversarial situations as well as in situations where an
amicable resolution is sought. Specific activities that we undertake as part of these services include claims preparation, analysis and review, litigation support, strategic advisory services, cost/damages assessment, delay/disruption analysis,
contract review and assessment, and expert witness testimony. Clients are typically billed based on an hourly rate for each consultant assigned to the project, and we are reimbursed for our out-of-pocket expenses.

##### Table of Contents

Our claims consulting clients include participants on all sides of a construction project, including
owners, contractors, subcontractors, architects, engineers, attorneys, lenders and insurance companies. We have been involved in resolving construction claims for many major construction projects worldwide, including for the Channel Tunnel
connecting the United Kingdom and France and the Petronas Twin Towers in Kuala Lumpur, Malaysia.

Global Business

In the recent past, the percentage of our CFR derived from overseas operations has risen considerably. In 2007, the Company revised the method by which it
allocates revenue to geographic areas for project management contracts. The Company now allocates revenue based on the site of the actual project which provides a more accurate portrayal of the areas in which the Company operates. Previously, the
Company allocated revenue based on the location of the client. For construction claims contracts, the Company allocates revenue based on the location of the office performing the work. The amounts for 2006 and 2005 have been revised to reflect the
new method. The following table sets forth the amount and percentage of our CFR by geographic region for each of the past three fiscal years:

Growth Organically and Through Acquisition

Our business has expanded through organic growth and the acquisition of a number of project management and claims consulting businesses. Since 1998, we
have completed 11 acquisitions.

We believe that our industry includes a number of small regional companies in a highly fragmented market.
We believe that we have significant experience and expertise in identifying, negotiating, completing and integrating acquisitions and view the acquisition of these smaller competitors as a key part of our growth strategy.

Acquisitions

Gerens Management Group,
S.A.

On February 15, 2008, Hill International, S.A., our wholly-owned subsidiary, acquired 60% of the outstanding capital
stock of Gerens Management Group, S.A. (Gerens), a Spanish-headquartered firm that provides project management services on major construction projects throughout Spain as well as in Western Europe and Latin America. The consideration
paid by Hill International S.A. was 10,800,000 ($15,800,000) in cash. The remaining minority stockholders of Gerens, who own 40% of the company, consist of Gerens Managing Director as well as a group of major Spanish savings banks.
Gerens, which has about 250 employees, changed its name to Gerens Hill International, S.A immediately after the acquisition.

Gerens is
headquartered in Madrid and has additional offices in Barcelona and Cancun, Mexico. The company has managed the construction of major projects in various sectors, including residential, commercial, healthcare, retail and leisure, infrastructure, and
hotels and resorts. Gerens brings together extensive knowledge

of the Spanish market and worldwide experience in the management and control of complex design and construction processes offering their clients project
management and independent technical consultancy services. In 2007, Gerens had unaudited total revenues of approximately 21,000,000 ($30,600,000). At December 31, 2007, Gerens had total unaudited backlog of approximately 27,300,000
($39,900,000).

In connection with the acquisition, Gerens shareholders, including Hill International S.A., entered into an agreement
whereby the minority shareholders have the right to compel Hill International S.A. to purchase any or all of their shares during the period from March 31, 2010 to March 31, 2020. Hill International S.A. also has the right to compel the
minority shareholders to sell any or all of their shares during the period from March 31, 2011 to March 31, 2021. The purchase price for such shares shall be the greater of (a) 18,000,000 increased by the General Price Index
(capped at 3.5% per annum) or (b) ten times the companys earnings before interest and income taxes for the prior fiscal year, multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding
at the time of the purchase. Such amount may be increased by increases in equity subsequent to the acquisition date, and can be paid in cash or shares of our common stock at the option of the sellers.

John Shreeves Holdings Ltd.

On January 4, 2008, Hill International (UK) Ltd., our wholly-owned subsidiary, acquired John Shreeves Holdings Ltd. and its operating subsidiary John Shreeves & Partners Ltd. (collectively Shreeves), a London-based
firm that provides project management and cost consultancy services on primarily private-sector projects throughout the United Kingdom. The acquired business will continue to operate under the Shreeves brand name until its operations have been
consolidated with Hills. For its last fiscal year, ended April 30, 2007, Shreeves had revenues of approximately £2,400,000 ($4,900,000). Total consideration amounted to £1,850,000 ($3,700,000) consisting of a cash payment of
£1,650,000 ($3,300,000) on the date of closing and a cash payment of £200,000 ($400,000) payable six months after the closing.

KJM & Associates, Ltd.

On May 10, 2007, we acquired all of the common stock of KJM &
Associates, Ltd. (KJM). KJM provides project management and project controls services primarily for the transportation and education markets. KJM is headquartered in Bellevue, Washington and provided the Companys Project Management
Group with new and expanded geographic coverage in Washington, Oregon, California, Arizona, Texas and New York.

We paid $9,350,000
consisting of $8,350,000 in cash plus 136,593 shares of restricted common stock of the Company (the Restricted Shares) initially valued at $1,000,000. The Restricted Shares were valued based on the average closing price of our common
stock for the 10 trading days prior to the closing date. The Restricted Shares are being held in escrow for one year as security for any indemnification obligations of KJMs selling stockholder. Since the Restricted Shares are subject to
forfeiture, they will not be considered outstanding for accounting purposes until the end of the contingency period, at which time the fair value of those shares actually distributed will be accounted for as additional purchase consideration.

James R. Knowles (Holdings) PLC

In 2006, Hill International S.A., our wholly-owned subsidiary, acquired James R. Knowles (Holdings) PLC (Knowles). The total consideration paid by Hill International S.A. for all the outstanding shares of
Knowles was approximately £7,000,000 ($13,000,000) excluding direct acquisition costs. Knowles is a construction claims consulting and dispute resolution firm, headquartered in Daresbury, United Kingdom and with offices worldwide. Knowles
provided us with opportunities to enter new geographic markets, such as Canada, Australia and Southeast Asia, while strengthening our position in overlapping markets, such as the United States, the United Kingdom and the Middle East.

Our five largest clients accounted for 7.5%, 7.3%, 2.7%, 2.3% and 1.9% of our CFR during fiscal
year 2007.

Business Development

The process for acquiring business from each of these categories of clients is principally the same, by participating in a competitive request-for-proposal (RFP) process, with the primary difference among clients being that the
process for public sector clients is significantly more formal and complex than for private sector clients as a result of government procurement rules and regulations that govern the public-sector process.

Although a significant factor in our business development consists of our standing in our industry, including existing relationships and reputation based
on performance on completed projects, our marketing department undertakes a variety of activities in order to expand our exposure to potential new clients. These activities include media relations, advertising, promotions, market sector initiatives
and maintaining our website and related web marketing. Media relations include placing articles that feature us and our personnel in trade publications and other media outlets. Our promotions include arranging speaking engagements for our personnel,
participation in trade shows and other promotional activities. Market sector initiatives are initiatives designed to broaden our exposure to specific sectors of the construction industry, such as, for example, participating in or organizing industry
seminars targeted to one sector of an industry.

For the year ended December 31, 2007, CFR from U.S. federal government contracts
represented approximately 15.1% of our total CFR. Doing business with governments, including the U.S. federal government, is complex and requires the ability to comply with intricate regulations and satisfy periodic audits. We believe that the
ability to understand these requirements and to successfully conduct business with government agencies is a barrier to entry for smaller, less experienced competitors. Most government contracts, including our contracts with the federal government,
are subject to termination by the government, to government audits and to continued appropriations.

We are required from time to time to
obtain various permits, licenses and approvals in order to conduct our business in some of the jurisdictions where we operate. The inability to obtain any particular permits, licenses or governmental approvals would not have a material affect on our
business. Our business of providing construction management and construction claims services are not subject to significant regulation by state, federal or foreign governments.

##### Table of Contents

Contracts

The price provisions of our contracts can be grouped into three broad categories: cost-plus, time and materials, and fixed-price. The majority of our contracts are of the cost-plus type category.

Cost-plus contracts provide for reimbursement of our costs and overhead plus a predetermined fee. Under some cost-plus contracts, our fee may be based
partially on quality, schedule and other performance factors.

We also enter into contracts whereby we bill our clients monthly at hourly
billing rates. The hourly billing rates are determined by contract terms. For governmental clients, the hourly rates are generally calculated as salary costs plus overhead costs plus a negotiated profit percentage. For commercial clients, the hourly
rate can be taken from a standard fee schedule by staff classification or it can be a discount from this schedule. In some cases, primarily for foreign work, a fixed monthly staff rate is negotiated rather than an hourly rate. This monthly rate is a
build-up of staffing costs plus overhead and a profit. Hill accounts for these contracts on a time-and-expenses method, recognizing revenue as costs are incurred.

Fixed price contracts are accounted for using the percentage-of-completion method, wherein revenue is recognized as costs are incurred. This type of contract has had a declining role in our business.

Backlog

We believe a strong
indicator of our future performance is our backlog of uncompleted projects under contract or awarded. Our backlog represents managements estimate of the amount of contracts and awards in hand that we expect to result in future consulting fee
revenue. Project management backlog is evaluated by management, on a project-by-project basis, and is reported for each period shown based upon the binding nature of the underlying contract, commitment or letter of intent, and other factors,
including the economic, financial and regulatory viability of the project and the likelihood of the contract being extended, renewed or cancelled. Construction claims backlog is based largely on managements estimates of future revenue based on
known construction claims assignments and historical results for new work. Because a significant number of construction claims may be awarded and completed within the same period, our actual construction claims revenue has historically exceeded
backlog by a significant amount.

Our backlog is important to us in anticipating and planning for our operational needs. Backlog is not a
measure defined in U.S. generally accepted accounting principles, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog.

At December 31, 2007, our backlog was approximately $416,000,000 compared to approximately $247,000,000 at December 31, 2006. We estimate that
approximately $196,000,000, or 47%, of the backlog at December 31, 2007 will be recognized during our 2008 fiscal year.

The schedule
below includes backlog under two categories: (1) contracts for which work authorizations have been or are expected to be received on a time and material basis, fixed-price basis and not-to-exceed projects that are well defined and
(2) contracts awarded to the company where some or all of the work has not yet been authorized. As of December 31, 2007, approximately $330,000,000, or 79%, of our backlog was in category (1) and approximately $86,000,000 or 21%, of
our backlog was in category (2). We do not track whether contracts included in our backlog are fully funded, incrementally funded, or unfunded.

Included in category (2) of 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. Also included in category (2) of our backlog is the amount of anticipated revenues in option years beyond the
base term of our contracts if we reasonably expect our clients to exercise

##### Table of Contents

such option years. Although backlog reflects business that we consider to be firm, cancellations or scope adjustments may occur. Further, substantially all
of our contracts with our clients may be terminated at will, in which case the client would only be obligated to us for services provided through the termination date. The impact of terminations and modifications on our realization of revenues from
our backlog has not been significant. Furthermore, reductions of our backlog as a result of contract terminations and modifications may be more than offset by additions to the backlog.

We adjust backlog to reflect project cancellations, deferrals and revisions in scope and cost (both upward and downward) known at the reporting date;
however, future contract modifications or cancellations may increase or reduce backlog and future revenues.

Competition

The project management and claims consulting industries are highly competitive. We compete for contracts, primarily on the basis of technical capability, with numerous entities, including design or engineering firms,
general contractors, other pure construction management companies, other claims consulting firms, the Big Four and other accounting firms, management consulting firms and other entities. Compared to us, many of these
competitors are larger, well-established companies that have broader geographic scope and greater financial and other resources. During 2007, some of our largest project management competitors included: AECOM Technology Corp.; Bovis Lend Lease,
Inc.; Heery International, Inc.; Jacobs Engineering Group, Inc.; Parsons Brinckerhoff, Inc.; Tishman Construction Corp.; Turner Construction Corp., and URS Corp. Some of our largest claims consulting competitors last year included: Exponent, Inc.;
FTI Consulting, Inc.; High-Point Rendel, Ltd. and Navigant Consulting, Inc.

Insurance

We maintain insurance covering professional liability, as well as for claims involving bodily injury and property damage. We have historically enjoyed a
favorable loss ratio in all lines of insurance and our management considers our present limits of liability, deductibles and reserves to be adequate. We endeavor to reduce or eliminate risk through the use of quality assurance/control, risk
management, workplace safety and similar methods to eliminate or reduce the risk of losses on a project. We have experienced and expect to continue to experience increases in our insurance premiums.

|Item 1A. | Risk Factors
|-------- | ------------

Our business involves a number of
risks, some of which are beyond our control. The risks and uncertainties described below are not the only ones we face. Such factors could have a significant impact on our business, operating results and financial condition. We believe the most
significant of these risks and uncertainties are as follows:

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



12



---

##### Table of Contents

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.

##### Table of Contents

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 receives 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



14



---

##### Table of Contents

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;

| | - |  | -------------------



| |  |  | 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
March 5, 2008, there were 38,353,829 shares of our common stock outstanding. An additional 875,000 shares of our common stock may be issued upon the exercise of options held by employees, management and directors. An additional 2,300,000 shares
will be issued in the second quarter of 2008 and an additional 2,000,000 shares may be issued in connection with earnout provisions of the merger agreement with Arpeggio. An additional 136,593 shares may be issued as contingent consideration for the
KJM acquisition. 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.

On September 23, 1996, William Hughes General Contractors, Inc. (Hughes) filed a complaint in the Superior Court of New Jersey, Law
Division, Gloucester County, against the Monroe Township Board of Education, the Company and other parties, alleging breach of contract and other causes of action in connection with its performance of a construction project for Monroe Township,
seeking in excess of $3,500,000 in damages. Monroe Township, which had terminated Hughes from the construction project prior to the commencement of the litigation on the basis of Hughes performance, made a cross claim against the Company and
other parties for contribution and indemnification. Monroe Township is seeking approximately $89,000 in damages from the Company, in addition to an indemnification for Hughes claims. In relation to the Hughes claims, a claim was made against
the Company by Fidelity and Deposit Company of Maryland (F&D). F&D is claiming damages in the range of $425,000 to $470,000. The F&D claim is being defended by the New Jersey Professional Liability Insurance Guarantee
Association (NJPLIGA) and losses are covered up to $300,000. We believe that the claims of Hughes, Monroe Township and F&D are without merit and, based on our current understanding and evaluation of the relevant facts and
circumstances, no accruals have been made for any of these claims because the Company considers the chance of loss to be remote.

On
September 22, 1999, Wartsila NSD North America, Inc. filed a complaint against the Company in the United States District Court for the District of New Jersey. Wartsila alleged negligence, breach of contract and fraud against the Company in
connection with plaintiffs hiring of a former Company employee and sought damages in excess of $7,300,000. A jury verdict was rendered on March 6, 2006. The jury found that the Company was negligent and breached the contract with
plaintiff but that the Company did not commit fraud. The jury awarded damages of approximately $2,000,000. The Company filed a Motion to Mold the Verdict and to

Enter Judgment consistent with the parties contract which contains a limitation of liability clause which limits the Companys liability, absent
fraud, to direct damages. In connection with the Arpeggio and Hill merger described in Note 2 to the consolidated financial statements, stockholders of the pre-merger Hill International, Inc. had escrowed a total 1,450,000 shares of the
Companys stock to satisfy non-tax indemnification claims by the Company arising out of this and certain other matters. Liability in this matter, if any, will ultimately be satisfied from such escrowed shares under the terms of an escrow
agreement. On June 28, 2006 the Court denied the Companys motion and the Company subsequently filed a Notice of Appeal on July 26, 2006 with the Third Circuit Court of Appeals. The Company has posted a letter of credit securing the
judgment plus pre-and post-judgment interest in the amount of $3,350,000. The Company also recorded a corresponding accrued liability in the amount of $3,350,000 included in Accrued liabilities on the Companys consolidated balance
sheet at December 31, 2007 and December 30, 2006. From the shares held in escrow, a total of 451,665 shares representing $3,350,000 has been allocated at this time to the Company for satisfaction of the judgment and will be placed in
treasury stock in the event the judgment is ultimately paid.

On May 28, 2004, Sims Group, Inc. (Sims) filed a Demand for
Arbitration with the American Arbitration Association alleging breach of contract against the Company. The plaintiff was a subcontractor to the Company and sought the alleged contract balance owed of approximately $1,300,000. The Company filed a
counterclaim on July 2, 2004 alleging fraud and breach of contract. This matter was arbitrated during April 2006 and an arbitration award was issued on June 28, 2006 awarding Sims $1,250,000 plus costs of $33,000. The Company had accrued a
liability of $772,000 related to this matter prior to September 30, 2005. In connection with the Arpeggio and Hill merger described in Note 2 to the consolidated financial statements, stockholders of the pre-merger Hill International, Inc. had
escrowed 1,450,000 shares of the Companys stock to satisfy non-tax indemnification claims by the Company arising out of this and certain other matters. Liability in this matter in excess of amounts accrued as of September 30, 2005 was to
be satisfied from such escrowed shares. In October 2006, the Company made a payment of approximately $1,300,000 to claimant to satisfy this matter in full. From the shares held in escrow, a total of 69,540 shares representing $515,777 were released
to the Company on July 16, 2007 for satisfaction of the judgment amount in excess of the amount accrued and have been placed in treasury.

On May 23, 2007, Hill filed a Demand for Arbitration with the American Arbitration Association alleging breach of contract, breach of the covenant of good faith and fair dealing, unjust enrichment and/or fraudulent inducement against
Bachmann Springs Holdings, LLC and Thomas Bachmann (hereinafter, collectively Bachmann). Hill was hired by Bachmann to provide professional support services and is demanding payment of invoices in the amount of $634,904, plus accrued
interest. On October 17, 2007, Bachmann filed a counterclaim with the American Arbitration Association alleging fraud and breach of contract and seeking damages in the amount of $8,600,000. We believe that Bachmanns counterclaim is
without merit and, based our current understanding and evaluation of the relevant facts and circumstances, no accruals have been made for this claim because the Company considers the chance of loss to be remote.

General Litigation

From time to time, we are
a defendant or plaintiff in various legal actions which arise in the normal course of business. As such we are required to assess the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. A determination
of the amount of the provision required for these commitments and contingencies, if any, which would be charged to earnings, is made after careful analysis of each matter. The provision may change in the future due to new developments or changes in
circumstances. Changes in the provision could increase or decrease our earnings in the period the changes are made. It is our opinion, after consultation with legal counsel, that the ultimate resolution of these matters should not have a material
adverse effect on the Companys financial condition, results of operations or cash flows.

Stockholders

As of March 5, 2008, there were 27 holders of record of our common stock. However, a single record stockholder account may represent multiple beneficial owners, including holders of shares in street name
accounts. Including those multiple owners, we believe there are approximately 1,100 holders of our common stock.

Dividends

We have not paid any dividends on our common stock. The payment of dividends in the future will be contingent upon our revenues and earnings, if any,
capital requirements and general financial condition of our business. The payment of any dividends is within the discretion of our board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in
our business operations and, accordingly, our board does not anticipate declaring any dividends in the foreseeable future.

Arpeggio Acquisition Corporation (Arpeggio) was incorporated in Delaware in 2004 as a specified purpose
acquisition corporation. On June 28, 2006, Arpeggio merged with Hill International, Inc. (Old Hill), a Delaware corporation, and Arpeggio was the surviving entity of the merger. Old Hill was founded in 1976 by our current Chairman
and Chief Executive Officer, Irvin E. Richter. Immediately following the merger, the stockholders of Old Hill owned approximately 63.6% of the total voting power of Arpeggio. The merger was accounted for as a reverse acquisition under U.S. generally
accepted accounting principles pursuant to which Old Hill was considered to be the acquiring entity and Arpeggio was the acquired company for accounting purposes, accompanied by a recapitalization of Old Hill. Accordingly, the historical financial
statements relate to the business of Old Hill and its consolidated subsidiaries. Following the merger, Arpeggio changed its name to Hill International, Inc. In this report, the terms Company, we, us,
our or Hill refer to Hill International, Inc.

Reimbursable expenses are reflected in equal amounts in both total
revenue and total direct expenses. Because these revenues/costs are subject to significant fluctuation from year to year, we measure the performance of many of our key operating metrics as a percentage of consulting fee revenue (CFR), as
we believe that this is a better and more consistent measure of operating performance than total revenue.

Overview

CFR increased $73,131,000, or 56.3%, from $129,987,000 in 2006 to $203,118,000 in 2007. CFR for the project management segment increased $38,290,000
principally due to strong organic growth in the Middle East/North Africa region and from the acquisition of KJM in May 2007. CFR for the construction claims segment increased $34,841,000 as we realized the full-year impact of the Knowles acquisition
(made in September 2006) as well as strong organic growth throughout the group.

Reimbursable expenses increased $19,720,000, or 29.2%,
from $67,485,000 in 2006 to $87,205,000 in 2007 principally due to the increased use of subcontractors in project management and the full-year impact of the Knowles acquisition in construction claims.

Cost of services increased $35,802,000, or 50.4%, from $71,022,000 in 2006 to $106,824,000 in 2007 as a result of an increase in employees needed to
support the increase in CFR.

Gross profit increased $37,329,000, or 63.3%, from $58,965,000 in 2006 to $96,294,000 in 2007 due to the
increase in CFR. Gross profit as a percent of CFR increased from 45.4% in 2006 to 47.4% in 2007 principally because CFR from construction claims represented a greater portion of our consolidated CFR. Construction claims has a significantly higher
gross profit margin than does project management.

Selling, general and administrative expenses increased $32,231,000, or 66.2%,
principally due to increases in staff and office costs to support the overall growth in business, increases in corporate staff in connection with

becoming a public company in 2006, the full-year impact of the Knowles acquisition and amortization of intangible assets acquired in the Knowles and KJM
acquisitions.

Equity in earnings of affiliates increased $1,141,000 from $1,080,000 in 2006 to $2,221,000 in 2007 due to a significant
increase in the scope of SBHs work for the Iraq Reconstruction Program.

Income taxes increased $254,000, or 10%, from $2,534,000 in
2006 to $2,788,000 in 2007 as taxable income increased $5,818,000, or 53%, from $11,114,000 in 2006 to $16,932,000 in 2007. We continue to realize a large portion of our pre-tax income from foreign jurisdictions which imposed lower income tax rates,
if any. We also realized a significant tax credit resulting from the reversal of a prior years uncertain tax position amounting to $648,000.

Net earnings increased $5,564,000, or 65%, from $8,580,000 in 2006 to $14,144,000 in 2007. Diluted earnings per common share were $0.45 in 2007 compared to $0.46 in 2006.

On October 23, 2007, the Company notified the warrant holders of its intention to redeem all outstanding warrants on November 23, 2007. As of
that date, all but 24,399 warrants had been exercised. The Company redeemed all remaining warrants at a price of $0.01 per warrant. During 2007, the Company received $67,878,000 in connection with the exercise of warrants.

Critical Accounting Policies

The
Companys consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, which require management to make subjective decisions, assessments and estimates about the effect of matters that are
inherently uncertain. As the number of variables and assumptions affecting the judgment increases, such judgments become even more subjective. While management believes its assumptions are reasonable and appropriate, actual results may be materially
different than estimated.

Commencing in 2007, we changed our reporting periods to coincide with the end of each calendar quarter. Prior to
2007, we utilized a 52-53 week fiscal year ending on the Saturday closest to December 31. The difference resulting from this change in reporting periods for the year ended December 31, 2007 is not significant.

Revenue Recognition

We
generate revenue primarily from consulting services. Revenue is generally recognized upon the performance of services. In providing these services, we may incur reimbursable expenses, which consist principally of amounts paid to subcontractors and
other third parties as well as travel and other job related expenses that are contractually reimbursable from clients. In accordance with Emerging Issues Task Force Issue (EITF) No. 99-19, Reporting Revenue Gross as a Principal
versus Net as an Agent, and EITF No. 01-14, Income Statement Characterization of Reimbursements Received for Out-of-Pocket Expenses Incurred, we have assessed the indicators provided in EITF No. 99-19 and determined
that we will include reimbursable expenses in computing and reporting our total contract revenues as long as we remain responsible to the client for the fulfillment of the contract and for the overall acceptability of all services provided.

We earn our revenues from cost-plus, fixed-price and time-and-materials contracts. If estimated total costs on any contract indicate a
loss, we charge the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims,
anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. Such revisions could occur at any time and the effects may be material.

The majority of our contracts are for work where we bill the client monthly at hourly billing rates. The
hourly billing rates are determined by contract terms. For governmental clients, the hourly rates are generally calculated as either (i) a negotiated multiplier of our direct labor costs or (ii) as direct labor costs plus overhead costs
plus a negotiated profit percentage. For commercial clients, the hourly rates are generally taken from a standard fee schedule by staff classification or they can be at a negotiated discount from this schedule. In some cases, primarily for foreign
work, a fixed monthly staff rate is negotiated rather than an hourly rate. This monthly rate is determined based upon a build up of direct labor costs plus overhead and profit. We account for these contracts on a time-and-expenses method,
recognizing revenue as costs are incurred.

A small percentage of our contracts are fixed price. We account for these contracts on the
percentage-of-completion method, wherein revenue is recognized as costs are incurred. Under the percentage-of-completion method for revenue recognition, we estimate the progress towards completion to determine the amount of revenue and
profit to be recognized. We generally utilize a cost-to-cost approach in applying the percentage-of-completion method, where revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred.

Under the percentage-of-completion method, recognition of profit is dependent upon the accuracy of estimates. We have a history of making reasonably
dependable estimates of contract revenue, the extent of progress towards completion and contract completion costs on our long-term construction management contracts. However, due to uncertainties inherent in the estimation process, it is possible
that actual completion costs may vary from estimates.

Allowance for Doubtful Accounts

We make ongoing estimates relating to the collectibility of our accounts receivable and maintain an allowance for estimated losses resulting from the
inability of our customers to make required payments. Estimates used in determining accounts receivable allowances are based on specific customer account reviews and historical experience of credit losses. We also apply judgment including
assessments about changes in economic conditions, concentration of receivables among customers and industries, recent write-off trends, rates of bankruptcy, and credit quality of specific customers. Unanticipated changes in the financial condition
of customers, the resolution of various disputes, or significant changes in the economy could impact the reserves required. At the end of our 2007 and 2006 fiscal years, the allowance for doubtful accounts was $5,143,000 and $3,373,000,
respectively.

Goodwill and Other Intangible Assets

Goodwill arising from acquisitions is not amortized but is instead tested for impairment at the reporting unit level at least annually in accordance with
the provisions of Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. Generally, we perform an impairment assessment during our third fiscal quarter. Application of the goodwill
impairment test requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for Hill, the period over which cash flows will occur, and determination
of the weighted average cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit.

Changes in future market conditions, our business strategy, or other factors could impact upon the future values of Hills reporting units, which
could result in future impairment charges.At December 31, 2007, total goodwill amounted to $21,587,000.

We amortize other
intangible assets over their estimated useful lives and review the long-lived assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Determining whether impairment has
occurred typically requires various estimates and assumptions,



25

##### Table of Contents

including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount
and the assets residual value, if any. In turn, measurement of an impairment loss requires a determination of fair value, which is based on the best information available. We use internal discounted cash flow estimates, quoted market prices
when available and independent appraisals, as appropriate, to determine fair value. We derive the required cash flow estimates from our historical experience and our internal business plans and apply an appropriate discount rate.

Income Taxes

We make
judgments and interpretations based on enacted tax laws, published tax guidance, as well as estimates of future earnings. These judgments and interpretations affect the provision for income taxes, deferred tax assets and liabilities and the
valuation allowance. The deferred tax assets were evaluated under the guidelines of SFAS No. 109, Accounting for Income Taxes, and a determination of the basis of objective factors was made that the net assets will be realized through
future years taxable income. In the event that actual results differ from these estimates and assessments, additional valuation allowances may be required. Effective January 1, 2007, the Company implemented Financial Accounting Standards
Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting for income tax benefits that are uncertain in nature.

Under FIN 48, a company recognizes a tax benefit in the financial statements for an uncertain tax position only if managements
assessment is that the position is more likely than not (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term tax position in
FIN 48 refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods. The accounting
interpretation also provides guidance on measurement methodology, derecognition thresholds, financial statement classification and disclosures, recognition of interest and penalties, and accounting for the cumulative-effect adjustment at the date of
adoption.

Stock Options

We follow the provisions of SFAS No. 123(R), Share-Based Payment, which require the measurement and recognition of compensation expense for all stock-based awards made to directors, employees and consultants. The awards include
stock options and restricted stock grants.

While fair value may be readily determinable for awards of stock, market quotes are not
available for long-term, nontransferable stock options because these instruments are not traded. We currently use the Black-Scholes option pricing model to estimate the fair value of options. Option valuation models require the input of highly
subjective assumptions, including but not limited to stock price volatility, expected life and stock option exercise behavior.

Contingencies

Management estimates are inherent in the assessment of our exposure to insurance claims that fall
below policy deductibles and to litigation and other legal claims and contingencies, as well as in determining our liabilities for incurred but not reported insurance claims. Significant judgments by us and reliance on third-party experts are
utilized in determining probable and/or reasonably estimable amounts to be recorded or disclosed in our financial statements. The results of any changes in accounting estimates are reflected in the financial statements of the period in which the
changes are determined. We do not believe that material changes to these estimates are reasonably likely to occur.

The increase in project management CFR consists of a $24,837,000 increase in foreign project
management CFR and a $13,453,000 increase in domestic project management CFR. The increase in foreign project management CFR was due to a $20,958,000 increase generated in the Middle East and $3,879,000 in Europe. Growth in our CFR in the Middle
East has been strong because there has been a significant increase in construction activity in a number of the countries in the Middle East (including the United Arab Emirates, Qatar, Kuwait, Bahrain, Saudi Arabia and Oman) where we do business. In
addition, our involvement with the Iraq reconstruction efforts funded by the United States government has led to additional work for us. The increase in domestic project management CFR revenue of $13,453,000 was primarily due to the acquisition of
KJM (effective May 2007) combined with an increase of $4,651,000 in the New York City office where several projects began in late 2006 and 2007.

The increase in construction claims CFR is due to a $31,911,000 increase in foreign construction claims CFR and an increase of $2,930,000 in domestic construction claims CFR. The increase in foreign construction claims revenue consists of
$24,897,000 generated in Europe and Asia/Pacific, reflecting the full-year impact of the Knowles acquisition (made in September 2006), a $3,640,000 increase in our London office (excluding Knowles) and a $3,374,000 increase in the Middle East,
primarily due to the Knowles acquisition. The Knowles operations in the U.S. and Middle East were fully consolidated into Hill by January 1, 2007, and integration of the other Knowles operations was completed during 2007. The increase in
domestic claims CFR is principally attributable to an increase of $2,242,000 in our New Jersey office resulting from significant awards of new work.

Reimbursable expenses consist of amounts paid to subcontractors and other third parties and travel
and other job related expenses that are contractually reimbursable from clients. These items are reflected as separate line items in both our revenue and cost of services captions in our consolidated statement of earnings. The increase in project
management reimbursable expenses was partially due to an $8,602,000 increase in reimbursable subcontractors fees in the New York City office combined with an increase of $867,000 due to the acquisition of KJM in May 2007, partially offset by
lower use of subcontractors overseas. We use subcontractors for a variety of reasons, such as providing at-risk construction services on contracts where such work is required

by a client (generally known as CM/Build contracts) since we do not provide such services. The New York City office projects are principally
CM/Build contracts which require more subcontracting work. The amount and timing of reimbursable expenses is dependent on the work performed, however we believe that the amount of reimbursable expenses in 2007 is indicative of the amount of
expenditures relative to revenues that we would expect in future periods. The increase in construction claims reimbursable expenses is due to the expansion of our business in Europe and Asia/Pacific in the amount of $6,268,000 primarily due to the
acquisition of Knowles and an increase of $2,390,000 in our London office.

Cost of services consists of labor expenses for time charged directly to contracts and
non-reimbursable job related travel and out-of-pocket expenses. The increase in project management cost of services is primarily due to an increase in direct labor of $20,644,000 required to produce the higher volume of CFR.

The cost of services for construction claims increased primarily due to an increase in direct labor of $14,987,000 required to produce the increase in
CFR. Cost of services as a percentage of CFR decreased in 2007 as compared to 2006 due to the increase in construction claims CFR as a percentage of total CFR. The construction claims business typically has a lower cost of services as compared to
the project management business.

The increase in gross profit is the result of the increase in CFR for both project management and
construction claims. The construction claims increase included $13,150,277 in Europe and Asia/Pacific primarily due to the Knowles acquisition. The increase in gross profit as a percentage of CFR is due to the higher portion of the CFR from
construction claims (principally due to the Knowles acquisition) which has significantly higher gross profit margins than project management. The project management increase included $10,900,000 in foreign project management and $6,625,000 in
domestic project management.

##### Table of Contents

The increase in SG&A expenses is primarily attributable to increases from the full year effect of the
2006 Knowles acquisition, the 2007 KJM acquisition and costs related to becoming a public company. The significant components of the change are as follows:



| |  |  | An increase in unapplied and indirect labor expense of $12,947,000 due to increases in staff required to produce and support the increase in revenue as well as the
build-up of corporate staffing in connection with becoming a public company. This increase includes $2,980,000 for KJM which was acquired effective May 1, 2007.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $10,476,000 due to the selling, general and administrative expenses of Knowles operations in Europe and Asia/Pacific, excluding amortization of
intangibles.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $1,478,000 in administrative travel expense related to corporate executive and business development travel in support of the Companys strategic
growth initiatives.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $1,106,000 in rent expense due to expansion in Europe in support of revenue and staff growth and $487,000 increase due to KJM.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $1,057,000 in outside accounting and consulting fees due to increased auditing and Sarbanes-Oxley compliance requirements principally associated with
becoming a public company in June 2006.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $853,000 in amortization expense due primarily to $630,000 of amortization of increased intangibles acquired in the Knowles acquisition, $365,000 in
the KJM acquisition and a decrease of $142,000 for other intangibles which were fully amortized by the end of 2006.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in bad debt expense of $1,385,000.
| | - |  | ----------------------------------------------



| |  |  | An increase of $701,000 in insurance expense due to the increase in work volume and offices overseas.
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | An increase in telephone expense of $511,000 due to the increase in staffing and work volume.

Equity in Earnings of Affiliates

Equity in
earnings of affiliates primarily reflects our proportionate share of the earnings of an affiliate, Stanley Baker Hill, LLC (SBH). SBH is a joint venture between Stanley Consultants, Inc. (Stanley), Michael Baker, Jr., Inc.
(Baker) and us. Stanley, Baker and we each own an equal one-third interest in SBH. SBH has a contract for an indefinite delivery and indefinite quantity for construction management and general architect-engineer services for facilities
in Iraq with the U.S. Army Corps of Engineers. The increase of $1,141,000 reflects the increased scope of SBHs services in support of the Iraq Reconstruction Program.

We received no distributions from the Pike/Hill joint venture during 2007.

Operating Profit

Operating profit increased $6,239,000, or 54.9%, from $11,373,000 in 2006 to
$17,612,000 in 2007, principally due to higher CFR and gross profit, partially offset by higher direct and SG&A expenses.

Interest Expense, net

Net interest expense increased $121,000 to $433,000 in 2007 as compared with $312,000 in 2006, primarily due to increased
borrowings for funds required for the acquisition of KJM.

Income Taxes

For 2007, we recognized an income tax expense of $2,788,000 compared to an income tax expense of $2,534,000 for 2006, principally relating to higher
taxable income in 2007.

##### Table of Contents

The effective tax rates for the years of 2007 and 2006 were 16% and 23%, respectively. Our effective tax
rate continues to decline because a greater portion of our profit comes from foreign operations which are taxed at lower rates, if at all. We also realized a significant tax credit in 2007 resulting from the reversal of a prior years uncertain
tax position amounting to $648,000 as required by FIN 48. Excluding this reversal, our effective tax rate would have been 20% in 2007. In February 2008, the Company realized a tax benefit of $2,506,000 upon the filing of certain income tax returns.
This amount will reduce income tax expense in the first quarter of 2008.

Net Earnings

Our net earnings in 2007 were $14,144,000, or $0.45 per diluted common share, based upon 31,387,000 diluted common shares outstanding as compared to net
earnings in 2006 of $8,580,000, or $0.46 per diluted common share, based upon 18,489,000 diluted common shares outstanding. The diluted earnings per share for 2007 were unfavorably impacted by significant increase in diluted shares outstanding as a
result of (i) the merger of Hill and Arpeggio in June 2006, (ii) warrants and options becoming more dilutive due to a significant increase in the market price of the Companys common stock in late 2007, and (iii) the exercise of
substantially all of the Companys warrants in late 2007. Net earnings improved by $5,564,000 or 64.8%, which was principally due to an increase in CFR, an increase in gross profit margin and a decline in the effective tax rate, partially
offset by higher direct and SG&A expenses.

The increase in project management CFR consists of a $25,045,000 increase in foreign project
management CFR and a $5,817,000 increase in domestic project management CFR. The increase in foreign project management CFR was due to a $22,570,000 increase generated in the Middle East and $2,476,000 in Europe. Growth in our CFR in the Middle East
has been strong because there has been a significant increase in construction activity in a number of the countries in the Middle East (including the United Arab Emirates, Qatar, Kuwait, Bahrain, Saudi Arabia and Oman) where we do business. In
addition, Iraq reconstruction efforts funded by the United States government have led to other additional work for us. The increase in domestic project management CFR was partially due to a $2,071,000 increase in the New York City office where
several projects began during 2005 and continued throughout 2006. CFR of $1,497,000 for the Las Vegas office also contributed to the increase in domestic project management revenue. The Las Vegas office was opened in January 2006.

The increase in construction claims CFR is due to a $19,893,000 increase in foreign construction claims revenue partially offset by an $876,000 decrease
in domestic construction claims revenue. The increase in foreign construction claims revenue primarily consists of $14,462,000 generated by the acquisition of Knowles in September 2006 and a $3,974,000 increase in London (excluding Knowles) of which
$1,887,000 is attributable to work generated by internal business development efforts and $2,087,000 attributable to new work generated by the acquisition of Pickavance in January 2006. The increase in foreign construction claims revenue also
includes a $1,456,000 increase in the Middle East due to continued growth. The decrease in domestic claims revenue of $876,000 is principally attributable to decreased work in the Washington D.C. office where two large claims assignments ended in
2005 and were not replaced with new work.

Reimbursable expenses consist of amounts paid to subcontractors and other third parties and travel
and other job related expenses that are contractually reimbursable from clients. The increase in project management reimbursable expense was partially due to a $19,414,000 increase in reimbursable subcontractors fees in the New York City
office as described above. In addition, reimbursable expense increased by $7,678,000 in Europe and $6,403,000 in Middle East projects due to continued increases in new work, offset by a $1,184,000 reduction in the use of subcontractors in the
Washington, D.C. projects. We use subcontractors for a variety of reasons, including providing at-risk construction services on contracts where such work is required by a client (generally known as CM/Build contracts) since we do not
provide such services. The New York City office projects are principally CM/Build contracts which require more subcontracting work. The amount and timing of reimbursable expenses is dependent on the work performed, however we believe that the amount
of reimbursable expenses in 2006 is indicative of the amount of expenditures relative to revenues that we would expect in future periods. The increase in construction claims reimbursable expenses is primarily due to Knowles in the amount of
$2,401,000.

Cost of services consists of labor expenses for time charged directly to contracts and
non-reimbursable job related travel and out-of-pocket expenses. The increase in project management cost of services of $19,176,000 is principally due to an increase in direct labor of $19,086,000 required to produce the increase in CFR of
$30,862,000.

The increase in construction claims cost of services of $8,570,000 is primarily due to Knowles cost of services of $6,792,000
and an increase in direct labor of $1,725,000 required to produce the increase in CFR of $4,554,000, excluding Knowles.

The increase in gross profit is the result of the increase in CFR for both project management and
construction claims. The construction claims increase included $7,669,000 from Knowles. The decline in gross profit as a percentage of CFR is due to the higher percentage of the CFR from overseas project management work where billing rates are
typically lower and costs are higher.

While SG&A increased by $16,811,000, or 52.8%, in 2006 as compared to 2005, these expenses
decreased from 39.8% to 37.4% as a percentage of CFR. The decline of SG&A as a percentage of CFR is partially attributable to our increase in project management revenues, which tend to have lower indirect expenses, and to our higher CFR growth
versus growth in overhead spending.

The increase in SG&A expenses of $16,811,000 is attributable to the following:



| |  |  | An increase of $6,405,000 due to the selling, general and administrative expenses of Knowles, excluding amortization of intangibles which is discussed below;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A net increase in unapplied and indirect labor expense of $5,188,000 due to increases in staff required to produce and support the increase in revenue. Unapplied
and indirect labor expenses in 2005 included $1,229,000 of non-cash, stock-based compensation expense as a result of the adoption of SFAS No. 123 (R);
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $1,117,000 in outside accounting fees due to increased auditing requirements and the cost of quarterly reviews principally associated with becoming a
public company;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in other office related expenses including postage, stationary, and printing and office maintenance of $495,000 due to overseas expansion;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in business development expense of $492,000 due to continued efforts in promoting new work including $216,000 in increased advertising expense;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $474,000 in rent expense due to expansion in the Middle East and Europe in support of revenue and staff growth;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | A net increase of $398,000 in other selling, general and administrative expenses due to a variety of factors;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $339,000 in amortization expense due primarily to amortization of intangibles in the amount of $302,000 on the Knowles acquisition and $37,000 on the
Pickavance acquisition;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $318,000 in depreciation expense of computer equipment and furniture due to increased staff and office space required in the Middle East and Europe;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in directors fees of $294,000 as a result of becoming a publicly-held company with an expanded board of directors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase of $274,000 in property and casualty insurance due to increase volume;

Equity in Earnings of Affiliates

Our share of
the earnings of an affiliate, Stanley Baker Hill, LLC (SBH), increased $306,000, from $685,000 in 2005 to $991,000 in 2006. Other earnings from joint ventures totaled $89,000 in 2006.

SBH is a joint venture between Stanley Consultants, Inc. (Stanley), Michael Baker, Jr., Inc. (Baker) and us. Stanley, Baker and
we each own an equal one-third interest in SBH. SBH has a contract for an indefinite delivery and indefinite quantity for construction management and general architect-engineer services for facilities in Iraq with the U.S. Army Corps of Engineers.

We also entered into an agreement with The Pike Company (Pike) in January 2005 to form a joint venture in order to provide
project management services to the U.S. General Services Administration. The joint venture agreement provides that each party will be reimbursed for all of its costs and that a project management fund shall pay other costs. Any profits from the
joint venture are to be split 60% to Pike and 40% to us. In 2006, we received distributions from the joint venture of approximately $89,000 and have included the distribution as equity in earnings of affiliates on our consolidated statement of
earnings. We received no distributions in 2005.

Operating Profit

Operating profit increased $5,717,000, or 101.1%, from a profit of $5,656,000 in 2005 to a profit of $11,373,000 in 2006 principally due to higher CFR and
gross profit, partially offset by higher direct and selling, general and administrative expenses. Included in this increase was $960,000 in operating profit for Knowles.

Interest Expense, net

Net interest expense decreased $357,000 to $312,000 in 2006 as compared
with $669,000 in 2005, principally due to the payoff of a credit line of $9,750,000 in June 2006 after the merger of Arpeggio and Hill.

Income Taxes

For 2006, we recognized an income tax expense of $2,534,000 compared to an income tax expense of $1,845,000 for 2005, principally
relating to higher taxable income in 2006.

The effective tax rates for the fiscal years of 2006 and 2005 were 23% and 37%, respectively.
The effective tax rate in 2006 is lower because a greater portion of our profit in 2006 came from foreign operations which are taxed at lower rates, if at all.

Net Earnings

We achieved net earnings in 2006 of $8,580,000, or $0.46 per diluted common share based upon 18,489,000
diluted common shares outstanding, as compared to net earnings in 2005 of $3,142,000, or $0.23 per diluted common share based upon 13,894,000 diluted common shares outstanding.The diluted earnings per common share for 2006 was unfavorably
impacted by additional diluted shares outstanding principally due to the merger of Hill and Arpeggio in June 2006. Overall profitability improved due to an increase in CFR, partially offset by higher direct, selling, general and administrative,
interest and tax expenses.

Credit Facilities

We are a party to a loan
and security agreement with LaSalle Bank N.A. (LaSalle), which provides for up to $35,000,000 to be made available to us on a revolving basis (the Credit Facility). The Credit Facility provides for a letter of credit
sub-facility of $20,000,000. The Credit Facility is secured by all of our assets, including, without limitation, our accounts receivable, equipment, securities, financial assets and the proceeds of the foregoing, as well as by a pledge of 66.67% of
the outstanding capital stock of the following subsidiaries: Hill International S.A., Hill International (UK) Ltd., Hill International (Middle East) Ltd. and James R. Knowles (Holdings) Ltd.

The Credit Facility is for a term extending until January 1, 2011. The Credit Facility provides for LIBOR loans and prime rate loans, payable at
margins above either LaSalles prime rate or LIBOR based on the Companys ratio of total debt to EBITDA ranging from 0 to 50 basis points above prime or 150 to 262.50 basis points above LIBOR. At December 31, 2007 the applicable
margins were 0 basis points above LaSalles prime rate and 150 basis points above LIBOR. The Credit Facility contains covenants with respect to our minimum net worth, total debt to EBITDA ratios, fixed charge coverage ratios and billed accounts
receivable to total debt ratios, as well as other financial covenants and certain restrictions on the incurrence of debt, on the making of investments, on the payment of dividends, on transactions with affiliates and other affirmative and negative
covenants and events of default customary for facilities of its type. At December 31, 2007, there were no outstanding borrowings under the Credit Facility, although the Company had $7,657,000 in outstanding letters of credit which reduced
availability under the Credit Facility.

We currently have two additional credit facilities with international financial institutions as follows:



| |  |  | A credit facility with a bank in the Middle East for 11,500,000 AED (approximately $3,134,000) collateralized by certain overseas receivables. The interest rate on
that facility is the Emirates InterBank Offer Rate (EIBOR), which at December 31, 2007 was 2.90%, plus 2.0%. At December 31, 2007, there were no outstanding borrowings under this facility which expires on December 24,
2008.

Acquisitions

Gerens Management Group,
S.A.

On February 15, 2008, Hill International, S.A., our wholly-owned subsidiary, acquired 60% of the outstanding capital
stock of Gerens Management Group, S.A. (Gerens), a Spanish-headquartered firm that provides project management services on major construction projects throughout Spain as well as in Western Europe and Latin America. The consideration
paid by Hill International S.A. was 10.8 million ($15.8 million) in cash.

In connection with the acquisition, Gerens
shareholders, including Hill International S.A., entered into an agreement whereby the minority shareholders have the right to compel Hill International S.A. to purchase any or all of their shares during the period from March 31, 2010 to
March 31, 2020. Hill International S.A. also has the right to compel the minority shareholders to sell any or all of their shares during the period from March 31, 2011 to March 31, 2021. The purchase price for such shares shall be the
greater of (a) 18.0 million increased by the General Price Index (capped at 3.5% per annum) or (b) ten times the companys earnings before interest and income taxes for the prior fiscal year, multiplied by a percentage
which the shares to be purchased bear to the total number of shares outstanding at the time of the purchase. Such amount may be increased by increases in equity subsequent to the acquisition date, and can be paid in cash or shares of our common
stock at the option of the sellers.

Payment of Judgments and Arbitration Awards

Twelve percent (12%) of the 14,500,000 shares of Arpeggio common stock issued at the time of the merger to former Hill stockholders (a total of
1,740,000 shares) were placed into escrow to secure the indemnity rights of Arpeggio under the Merger Agreement and are governed by the terms of an Escrow Agreement. The shares were divided into two tranches: (a) 1,450,000 shares to cover
non-tax indemnities (Basic Indemnity Shares) and (b) 290,000 shares to cover tax indemnities (Tax Indemnity Shares). These shares, minus any shares applied in satisfaction of a claim for indemnification, were scheduled
to be returned to the stockholders on the following dates: April 30, 2007 for the Basic Indemnity Shares and December 31, 2010 for the Tax Indemnity Shares. At April 30, 2007, a total of 465,160 shares were allocated to the Company
for satisfaction of certain claims and will be placed in treasury stock in the event the claims are ultimately paid. Effective April 30, 2007, a total of 915,300 Basic Indemnity Shares were released to the former stockholders of Old Hill. The
remaining 465,160 Basic Indemnity Shares and the Tax Indemnity Shares were retained in escrow. Although we may receive shares with respect to any claims, we will be required to pay any adverse judgments in cash.

Adverse judgments were rendered against Hill in the Sims and Wartsila matters. In October 2006, we made a payment of approximately $1,300,000 to claimant
to satisfy the Sims matter. We have received 69,540 escrowed shares with respect to that claim. While the Wartsila judgment is being appealed, we are required to provide a letter of credit for the full amount of the judgment. In July 2006, we
provided cash collateral of $3,350,000 for the letter of credit; such funds were returned to us in May 2007 following our provision of a substitute letter of credit under our Credit Facility.

Additional Capital Resources

We experienced a
significant increase in our cash balances during the fourth quarter of 2007 due to the exercise of approximately 12,399,000 warrants to purchase our common stock at $5.00 per share. At December 31, 2007, our cash and cash equivalents amounted
to approximately $66,128,000. We cannot provide any assurance that other sources of financing will be available, or if available, that the financing will be on terms acceptable to us.

Cash Flow Activity During the Year Ended December 31, 2007

For the year ended December 31,
2007, our cash increased by $54,909,000 to $66,128,000 at December 31, 2007. Cash provided by operations was $2,895,000, cash used in investing activities was $6,800,000 and cash provided by financing activities was $59,661,000. We also
experienced a decrease in cash of $847,000 from the effect of foreign currency exchange rate fluctuations.

Operating Activities

Net cash provided by operating activities for the year ended December 31, 2007 was $2,895,000. Cash provided by operations is attributable to net

Investing Activities

Net cash used in investing activities was $6,800,000. We spent $3,121,000 to purchase
computers, office equipment, furniture and fixtures and used $8,499,000, net of cash acquired, on the KJM acquisition. We received $3,350,000 previously held as collateral for a letter of credit in connection with a legal judgment against the
Company. We also received $1,528,000 as a distribution from an affiliate.

Financing Activities

Net cash provided by financing activities was $59,661,000. We received $67,878,000 from the exercise of warrants. Most of these funds were received in the
fourth quarter due to the Companys call of the warrants on October 23, 2007. This permitted the Company to repay $7,664,000 of outstanding borrowings under its credit facility. We also made payments on other bank borrowings amounting to
$488,000, on our capital leases amounting to $223,000 and $166,000 as distributions to a subsidiarys minority stockholders. Due to bank increased $324,000 due to the timing of certain payments which were disbursed but not immediately funded by
the bank.

Recent Accounting Pronouncements

FASB Statement No. 157

In September 2006, the FASB issued SFAS No. 157,
Fair Value Measurements, which became effective on January 1, 2008. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair
value measurements. Implementation of SFAS No. 157 will not have a material impact on our financial statements.

FASB Staff Position
No. 157-1

In February 2008, the FASB issued FASB Staff Position (FSP) No. 157-1, Application of FASB
Statement No. 157 to FASB Statement No. 13 and Its Related Interpretive Accounting Pronouncements That Address Leasing Transactions, which became effective for the Company on January 1, 2008. This FSP excludes FASB Statement
No. 13, Accounting for Leases, and its related interpretive accounting pronouncements from the provisions of SFAS No. 157. Implementation of this standard will not have a material effect on our financial statements.

FASB Staff Position FAS No. 157-2

In
February 2008, the FASB issued FSP No. 157-2,Effective Date of FASB Statement No. 157,which delays the Companys January 1, 2008 effective date of SFAS No. 157 for all nonfinancial assets and nonfinancial
liabilities, except those recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), until January 1, 2009. Implementation of this standard is not expected to have a material effect on our
financial statements.

FASB Statement No. 159

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial LiabilitiesIncluding an amendment of FASB Statement No. 115,which became
effective for the company on January 1, 2008. This standard permits companies to choose to measure many financial instruments and certain other items at fair value and report unrealized gains and losses in earnings. Such accounting is optional
and is generally to be applied instrument by instrument. Implementation of SFAS No. 159 will not have a material effect on our financial statements.

FASB Statement No. 141 (revised 2007)

In December 2007, the FASB issued SFAS
No. 141(revised 2007), Business Combinations, which will become effective for business combination transactions having an acquisition date on or after January 1, 2009. This standard requires the acquiring entity in a business
combination to recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date to be measured at their respective fair values. The Statement requires acquisition-related costs, as well
as restructuring costs the acquirer expects to incur for which it is not obligated at acquisition date, to be recorded against income rather than included in purchase-price determination. It also requires recognition of contingent arrangements at
their acquisition-date fair values, with subsequent changes in fair value generally reflected in income.

FASB Statement No. 160

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment
of ARB No. 51,which will become effective for the Company January 1, 2009, with retroactive adoption of the Statements presentation and disclosure requirements for existing minority interests. This standard will require
ownership interests in subsidiaries held by parties other than the parent to be presented within the equity section of the consolidated balance sheet but separate from the parents equity. It will also



38



---

##### Table of Contents

require the amount of consolidated net income attributable to the parent and the noncontrolling interest to be clearly identified and presented on the face
of the consolidated income statement. Certain changes in a parents ownership interest are to be accounted for as equity transactions and when a subsidiary is deconsolidated, any noncontrolling equity investment in the former subsidiary is to
be initially measured at fair value. We do not anticipate the implementation of SFAS No. 160 will significantly change the presentation of our consolidated income statement or consolidated balance sheet.

Staff Accounting Bulletin No. 110

In
December 2007, the SEC released Staff Accounting Bulletin (SAB) No. 110 which indicates that the staff will continue to accept, under certain circumstances, the use of the simplified method in developing an estimate of the expected
term for plain vanilla options in accordance with SFAS No. 123(R), Share-Based Payment. The Company has no historical data on which to base its estimate (see Note 13 to the Companys consolidated financial statements),
and, accordingly, it will continue to use the simplified method until such historical data becomes available.

Quarterly Fluctuations

Our operating results vary from period to period as a result of the timing of projects and the growth of our business. We do not believe that our business
is seasonal.

##### Table of Contents

|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

The Company is exposed to risks
associated with foreign currency fluctuations and changes in interest rates. The Companys exposure to foreign currency fluctuation relates primarily to its operations denominated in British pounds sterling, Euros, U.A.E. Dirhams, as well as
other currencies. Exchange rate fluctuations impact the U.S. dollar value of reported earnings derived from these foreign operations as well as the Companys investment in the net assets related to these operations.

All of our borrowings under our revolving credit facilities bear interest at variable rates. If market interest rates had changed by 100 basis points,
interest expense and our cash flows would have changed by $84,000 and $51,000, respectively.

its fiscal year to end on December 31. Prior to 2007, the Company utilized a 52-53 week fiscal year ending on the Saturday closest to December 31. The difference resulting from this change in reporting period is not significant.

Arpeggio Acquisition Corporation

Arpeggio was incorporated in Delaware on April 2, 2004 as a blank check company, the objective of which was to acquire an operating business in the United States or Canada. The Companys initial stockholders purchased 1,500,000
common shares, $.0001 par value, for $25,000 on April 2, 2004.

On June 30, 2004, Arpeggio consummated an Initial Public Offering
(Offering) and raised net proceeds of approximately $36,800,000. Arpeggio sold 6,800,000 Units in the Offering, which included 300,000 Units subject to the underwriters overallotment option. Each Unit consisted of one share of the
Companys common stock, $.0001 par value, and two Redeemable Common Stock Purchase Warrants as described in Note 15. Approximately $36,700,000 was deposited into an interest bearing trust account (Trust Fund) until the earlier of
(i) the consummation of its first Business Combination or (ii) the liquidation of Arpeggio. The remaining net proceeds were used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and
administrative expenses.

Merger and Accounting Treatment

On June 28, 2006, Arpeggio consummated a merger with Hill International, Inc., a Delaware corporation (Old Hill), in which Old Hill merged with and into Arpeggio pursuant to an Agreement and Plan of
Merger dated December 5, 2005, as amended (the Merger Agreement), among Arpeggio, Old Hill and certain stockholders of Old Hill. The stockholders of Old Hill received 14,500,000 shares of Arpeggios common stock in exchange for
all of the outstanding common shares of Old Hill. Immediately following the merger, the stockholders of Old Hill owned approximately 63.6% of the total voting power of Arpeggio. Accordingly, the merger was accounted for as a reverse acquisition
under U.S. generally accepted accounting principles pursuant to which Old Hill was considered to be the acquiring entity and Arpeggio was the acquired company for



46

##### Table of Contents

accounting purposes, accompanied by a recapitalization of Old Hill. As a result of this reverse purchase accounting treatment, (i) the historical
financial statements presented for periods prior to the date of the merger are no longer the historical financial statements of Arpeggio; (ii) the historical financial statements for periods prior to the date of the merger are those of Old
Hill, (iii) all references to the historical financial statements of the Company apply to the historical financial statements of Old Hill prior to and subsequent to the merger, and (iv) any references to Arpeggio apply solely to that
company and its financial statements prior to the merger.

Twelve percent (12%) or 1,740,000 of the 14,500,000 shares of Arpeggio
common stock issued to the Old Hill stockholders at the time of the merger were placed into escrow to secure the indemnity rights of Arpeggio under the Merger Agreement and are governed by the terms of an escrow agreement. The shares were divided
into two tranches: (a) 1,450,000 shares to cover non-tax indemnities (Basic Indemnity Shares) and (b) 290,000 shares to cover tax indemnities (Tax Indemnity Shares). These shares, minus any shares applied in
satisfaction of a claim for indemnification, were to be returned to the stockholders on the following dates: April 30, 2007 for the Basic Indemnity Shares and December 31, 2010 for the Tax Indemnity Shares. At April 30, 2007, a total
of 465,160 shares were allocated to the Company for satisfaction of certain claims and will be placed in treasury stock in the event the claims are ultimately paid. Effective April 30, 2007, a total of 915,300 of the Basic Indemnity Shares were
released to the stockholders. The remaining 465,160 Basic Indemnity Shares and 290,000 Tax Indemnity Shares were retained in escrow.

One
Arpeggio stockholder, owning 3,900 shares of Arpeggio common stock, voted against the merger and requested to receive his pro rata share of cash in the Trust Fund. The combined company remitted to that stockholder approximately $24,000 in exchange
for his shares.

The Company agreed to withhold its common stock due to certain Old Hill option holders and to remit to the proper taxing
authorities payment for income taxes due on income realized by them from the exercise of their options. The total amount remitted to the taxing authorities was approximately $2,800,000 and the Company received 529,742 shares of its common stock
which is included in treasury stock.

The Merger Agreement also provides for Old Hills stockholders to receive up to an additional
6,600,000 shares of the combined companys common stock, contingent upon the combined company attaining certain earnings targets as follows:



|            |  |                                    |            |                   |          
|----------- |  | ---------------------------------- | ---------- | ----------------- | ---------
|Fiscal year |  | Earnings before interest and taxes |            | Contingent shares
|2006        |  | $                                  | 9,900,000  |                   | 2,300,000
|2007        |  | $                                  | 13,500,000 |                   | 2,300,000
|2008        |  | $                                  | 18,400,000 |                   | 1,000,000
|2009        |  | $                                  | 24,900,000 |                   | 1,000,000

The Company met the earnings targets for the fiscal years ended December 31, 2007 and
December 30, 2006 and therefore 2,300,000 shares of the Companys common stock were issued during the second quarter of 2007 and 2,300,000 shares will be issued during the second quarter of 2008 to the former stockholders of Old Hill.

In connection with the approval of the above described transaction, the Arpeggio stockholders adopted, among other matters, the following:



| |  |  | An amendment to the Certificate of Incorporation of Arpeggio to change the name of Arpeggio from Arpeggio Acquisition Corporation to Hill International, Inc.;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An amendment to the Certificate of Incorporation of Arpeggio to increase the number of authorized shares of Arpeggio common stock from 30,000,000 to 75,000,000; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The 2006 Employee Stock Option Plan, which reserves 1,140,000 shares of common stock for issuance in accordance with the plans terms.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Upon consummation of the merger, approximately $37,500,000 was released from trust to be used by the
combined company. The total direct and incremental costs of approximately $3,400,000 million incurred by the Company for professional services in connection with the merger were reflected as a reduction of additional paid-in capital as of the
effective date of the merger.



|(b) | Use of Estimates
|--- | ----------------

The preparation of
financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The estimates affecting the consolidated financial
statements that are particularly significant include revenue recognition, recoverability of long-lived assets, income taxes, allowance for doubtful accounts and commitments and contingencies.



|(c) | Foreign Currency Translations and Transactions
|--- | ----------------------------------------------

Assets and liabilities of all foreign operations are translated at year-end rates of exchange, and the statements of operations are translated at the average rates of exchange for the year. Gains or losses resulting from translating foreign
currency financial statements are accumulated in a separate component of stockholders equity until the entity is sold or substantially liquidated.

Gains or losses from foreign currency transactions (transactions denominated in a currency other than the entitys local currency) are generally included in net income.



|(d) | Fair Value of Financial Instruments
|--- | -----------------------------------

The
fair value of financial instruments, which primarily consists of cash and cash equivalents, net receivables and accounts payable, approximates carrying value due to the short-term nature of the instruments. The carrying value of long-term debt
approximates its fair value as the interest rate is variable.



|(e) | Cash and Cash Equivalents
|--- | -------------------------

Cash and cash
equivalents include cash on hand and investments in money market funds and investment grade securities held with high quality financial institutions. The Company considers all highly liquid instruments purchased with a remaining maturity of three
months or less at the time of purchase to be cash equivalents.



|(f) | Restricted Cash
|--- | ---------------

Restricted cash primarily
represents advance payments from clients required to be maintained in foreign accounts to serve as collateral for bonds or guarantees on several projects. The cash will remain restricted until the respective project has been completed, which
typically is greater than one year. At December 30, 2006, the Company had posted a letter of credit securing the judgment in the Wartsila matter (see Note 18) amounting to $3,350,000. The letter of credit was secured by a cash deposit which is
included in Cashrestricted under current assets on the Companys consolidated balance sheet.



|(g) | Concentrations of Credit Risk
|--- | -----------------------------

Financial
instruments that potentially subject the Company to concentrations of credit risk consist principally of cash investments and accounts receivable.



48



---

##### Table of Contents

The Company maintains its cash accounts with high quality financial institutions. The Company provides
professional services, under contractual arrangements, to domestic and foreign governmental units, institutions and the private sector. To reduce credit risk, the Company performs ongoing credit evaluations of its clients and does not require
collateral beyond customary retainers.

The Company had one client that accounted for 17% of total revenue in 2007, two clients that
collectively accounted for a total of 30% of total revenue in 2006, and one customer that accounted for 19% of total revenue in 2005.

The
Company had one client that accounted for 12% of accounts receivable at December 31, 2007 and one client that accounted for 10% of accounts receivable at December 30, 2006.

The Company has several contracts with U.S. federal government agencies that accounted for 12%, 8% and 16% of total revenue during the fiscal years 2007,
2006 and 2005, respectively.



|(h) | Allowance for Doubtful Accounts
|--- | -------------------------------

The
allowance for doubtful accounts is an estimate prepared by management based on identification of the collectibility of specific accounts and the overall condition of the receivable portfolios. When evaluating the adequacy of the allowance for
doubtful accounts, the Company specifically analyzes trade receivables, including retainage receivable, historical bad debts, client credits, client concentrations, client credit worthiness, current economic trends and changes in client payment
terms. If the financial condition of clients were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Likewise, should the Company determine that it would be able to realize more of
its receivables in the future than previously estimated, an adjustment to the allowance would increase income in the period such determination was made. The allowance for doubtful accounts is reviewed on a quarterly basis and adjustments are
recorded as deemed necessary.



|(i) | Property and Equipment
|--- | ----------------------

Property and
equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is provided over the estimated useful lives of the assets as follows:



|                                |  |               |  |                                               
|------------------------------- |  | ------------- |  | ----------------------------------------------
|                                |  | Method        |  | Estimated Useful Life                         
|Furniture and equipment         |  | Straight-line |  | 10 years                                      
|Leasehold improvements          |  | Straight-line |  | Shorter of estimated useful life or lease term
|Computer equipment and software |  | Straight-line |  | 3 to 5 years                                  
|Automobiles                     |  | Straight-line |  | 5 years                                       

Under the provisions of Statement of Position 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use, the Company capitalizes costs associated with internally developed and/or purchased software systems the have reached the application development stage and meet recoverability tests. Capitalized
costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, payroll and payroll-related expenses for employees who are directly associated with and devote time to the internal-use software
project. Capitalization of such costs begins when the preliminary project stage is complete and ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Costs for general and administrative,
overhead, maintenance and training, as well as the cost of software that does not add functionality to existing systems, are expensed as incurred.



49

##### Table of Contents

Upon retirement or other disposition of these assets, the cost and related depreciation are removed from
the accounts and the resulting gain or loss, if any, is reflected in results of operations. Expenditures for maintenance, repairs and renewals of minor items are charged to expense as incurred. Major renewals and improvements are capitalized.



|(j) | Retainage Receivable
|--- | --------------------

Retainage receivable
represents balances billed but not paid by clients pursuant to retainage provisions in the construction management contracts and will be due upon completion of specific tasks or the completion of the contract. The current portion of retainage
receivable is included in accounts receivable in the Consolidated Balance Sheets. The long-term portion of retainage receivable is included in retainage receivable in the Consolidated Balance Sheets.



|(k) | Long-Lived Assets
|--- | -----------------

Acquired intangible
assets consist of contract rights, customer related intangibles and trade names arising from the Companys acquisitions. These assets are amortized over their estimated lives which range from three to ten years.

The Company follows the provisions of SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which establishes
accounting standards for the impairment of long-lived assets such as property and equipment and intangible assets subject to amortization. The Company reviews long-lived assets to be held-and-used for impairment whenever events or changes in
circumstances indicate that the carrying amount of the assets may not be recoverable. If the sum of the undiscounted expected future cash flows over the remaining useful life of a long-lived asset is less than its carrying amount, the asset is
considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. When fair values are not available, the Company estimates fair value using the expected future
cash flow discounted at a rate commensurate with the risks associated with the recovery of the asset. Assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.



|(l) | Goodwill
|--- | --------

Goodwill consists of the excess of
cost over the fair value of net assets acquired in business combinations accounted for as purchases.

The Company follows the provision of
SFAS No. 142,Goodwill and Other Intangible Assets. SFAS No. 142 requires an annual impairment test for goodwill and intangible assets with indefinite lives. Under SFAS No. 142, the first step of the impairment test requires
that the Company determine the fair value of each reporting unit, and compare the fair value to the reporting units carrying amount. To the extent a reporting units carrying amount exceeds its fair value, an indication exists that the
reporting units goodwill may be impaired and the Company must perform a second more detailed impairment assessment. The second impairment assessment involves allocating the reporting units fair value to all of its recognized and
unrecognized assets and liabilities in order to determine the implied fair value of the reporting units goodwill as of the assessment date. The implied fair value of the reporting units goodwill is then compared to the carrying amount of
goodwill to quantify an impairment charge as of the assessment date.

Application of the goodwill impairment test requires significant
judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the businesses, the useful life over which cash flows will occur, and determination of the Companys
weighted average cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or conclusions on goodwill impairment for each reporting unit. The Company performed its annual impairment test
effective July 1, 2007 and noted no impairment for either of its reporting units. In the future, the



50



---

##### Table of Contents

Company will continue to perform the annual test during its fiscal third quarter unless events or circumstances indicate an impairment may have occurred
before that time.



|(m) | Investment in Affiliate
|--- | -----------------------

The Company owns a
one-third interest in Stanley Baker Hill, LLC (SBH), which is accounted for using the equity method. SBH was formed on April 8, 2004 for the purpose of providing various architect-engineer and construction management services in
connection with the Iraq Reconstruction Program.

The Company will, in the ordinary course, form joint ventures for specific projects.
These joint ventures typically require no investment and provide a pass-through for the Companys billings. Any distributions in excess of the Companys billings are accounted for as income when received.



|(n) | Due to Bank
|--- | -----------

Under the Companys
cash-management system, certain cash accounts reflect credit balances to the extent checks were disbursed but not immediately funded at the bank. The Company manages this process daily and ensures all checks are funded when presented. The amounts of
these credit balances were approximately $942,000 and $618,000 at December 31, 2007 and December 30, 2006, respectively.



|(o) | Deferred Revenue
|--- | ----------------

In certain instances the
Company may collect advance payments from clients for future services. Upon receipt, the payments are reflected as deferred revenue in the Companys Consolidated Balance Sheet. As the services are performed, the Company reduces the balance and
recognizes revenue.



|(p) | Deferred Rent
|--- | -------------

Rent expenses related to
operating leases where scheduled rent increases exist is determined by expensing the total amount of rent due over the life of the operating lease on a straight-line basis. The difference between the rent paid under the terms of the lease and the
rent expensed on a straight-line basis is recorded as a liability. The non-current portion of deferred rent at December 31, 2007 and December 30, 2006 was 614,000 and $633,000, respectively, and is included in other liabilities on the
consolidated balance sheets. The current portion of deferred rent at December 31, 2007 and December 30, 2006 was $58,000 and $49,000, respectively, and is included in other current liabilities on the consolidated balance sheets.



|(q) | Income Taxes
|--- | ------------

The Company is required to
estimate income taxes in each of the jurisdictions in which it operates. This process involves estimating its actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and
accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Companys Consolidated Balance Sheets. The Company must assess the likelihood that the deferred tax assets will be recovered
from future taxable income and to the extent it believes recovery is not likely, the Company must establish a valuation allowance. To the extent the Company establishes a valuation allowance in a period; it must include an expense within the tax
provision in the consolidated statements of earnings. The Company has recorded a valuation allowance to reduce the deferred tax asset to an amount that is more likely than not to be realized in future years. If the Company determines in the future
that it is more likely than not that the net deferred tax assets would be realized, then the previously provided valuation allowance would be adjusted. Effective December 31, 2006, the Company implemented Financial Accounting Standards Board
(FASB) Interpretation No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting for income tax benefits that are uncertain in nature.

Under FIN 48, a company recognizes a tax benefit in the financial statements for an uncertain tax position only if managements
assessment is that the position is more likely than not (i.e., a likelihood greater than



51

##### Table of Contents

50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term tax position in FIN 48
refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods. The accounting
interpretation also provides guidance on measurement methodology, derecognition thresholds, financial statement classification and disclosures, recognition of interest and penalties, and accounting for the cumulative-effect adjustment at the date of
adoption.



|(r) | Revenue Recognition
|--- | -------------------

The Company generates
revenue primarily from construction management consulting services. Revenue is generally recognized upon the performance of services. In providing these services, the Company may incur reimbursable expenses, which consist principally of amounts paid
to subcontractors and other third parties and travel and other job related expenses that are contractually reimbursable for clients. In accordance with Emerging Issues Task Force Issue No. (EITF) 99-19, Reporting Revenue Gross as a
Principal versus Net as an Agent, and EITF 01-14, Income Statement Characterization of Reimbursements Received for Out-of-Pocket Expenses Incurred, the Company has assessed the indicators provided in EITF 99-19 and determined
that it will include reimbursable expenses in computing and reporting its total revenue as long as the Company remains responsible to the client for the fulfillment of the contract and for the overall acceptability of all services provided.

The Company earns its revenues from time-and-materials, cost-plus and fixed-price contracts. If estimated total costs on any contract
indicate a loss, the Company charges the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change
orders, claims, anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. Such revisions could occur at any time and the effects may be material.

Time-and-Materials Contracts

Under
its time-and-materials contracts, the Company negotiates hourly billing rates and charges its clients based on the actual time that the Company spends on a project. In addition, clients reimburse the Company for its actual out-of-pocket costs of
materials and other direct incidental expenditures that the Company incurs in connection with its performance under the contract. Its profit margins on time-and-materials contracts fluctuate based on actual labor and overhead costs that the Company
directly charges or allocates to contracts compared with negotiated billing rates. Revenues on these contracts are recognized based on the actual number of hours the Company spends on the projects plus any actual out-of-pocket costs of materials and
other direct incidental expenditures that the Company incurs on the projects. Its time-and-materials contracts also generally include annual billing rate adjustment provisions.

Cost-Plus Contracts

The Company has two major types of cost-plus contracts:

Cost-Plus Fixed Fee

Under cost-plus
fixed fee contracts, the Company charges its clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. In negotiating a cost-plus fixed fee contract, the Company estimates all recoverable direct and indirect costs
and then adds a fixed profit component. The total estimated cost plus the negotiated fee represents the total contract value. The Company recognizes revenues based on the actual labor costs, based on hours of labor effort, plus non-labor costs the
Company incurs, plus the portion of the fixed fee the Company has earned to date. The Company invoices for its services as revenues are recognized or in accordance with agreed-upon billing schedules. Aggregate revenues from cost-plus fixed fee
contracts may vary based on the actual number of labor hours worked and other actual contract costs incurred. However, if actual



52



---

##### Table of Contents

labor hours and other contract costs exceed the original estimate agreed to by its client, the Company generally must obtain a change order, contract
modification, or successfully prevail in a claim in order to receive additional revenues relating to the additional costs (see Change Orders and Claims).

Cost-Plus Fixed Rate

Under its
cost-plus fixed rate contracts, the Company charges clients for its costs plus negotiated rates based on its indirect costs. In negotiating a cost-plus fixed rate contract, the Company estimates all recoverable direct and indirect costs and then
adds a profit component, which is a percentage of total recoverable costs to arrive at a total dollar estimate for the project. The Company recognizes revenues based on the actual total number of labor hours and other costs the Company expends at
the cost plus the fixed rate the Company negotiated. Similar to cost-plus fixed fee contracts, aggregate revenues from cost-plus fixed rate contracts may vary and the Company generally must obtain a change order, contract modification, or
successfully prevail in a claim in order to receive additional revenues relating to any additional costs that exceed the original contract estimate (see Change Orders and Claims).

Labor costs and subcontractor services are the principal components of its direct costs on cost-plus contracts, although some include materials and other
direct costs. Some of these contracts include a provision that the total actual costs plus the fee will not exceed a guaranteed price negotiated with the client. Others include rate ceilings that limit the reimbursement for general and
administrative costs, overhead costs and materials handling costs. The accounting for these contracts appropriately reflects such guaranteed price or rate ceilings.

Firm Fixed-Price (FFP) Contracts

The Companys FFP contracts have historically
accounted for most of its fixed-price contracts. Under FFP contracts, the Companys clients pay it an agreed amount negotiated in advance for a specified scope of work. The Company recognizes revenues on FFP contracts using the
percentage-of-completion method (recognizing revenue as costs are incurred). Profit margins the Company recognizes in all periods prior to completion of the project on any FFP contract depend on the accuracy of the Companys estimates of
approximate revenue and expenses and will increase to the extent that its current estimates of aggregate actual costs are below amounts previously estimated. Conversely, if the Companys current estimated costs exceed prior estimates, its
profit margins will decrease and the Company may realize a loss on a project. In order to increase aggregate revenue on the contract, the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in
order to receive payment for the additional costs (see Change Orders and Claims).

Change Orders and Claims

Change orders are modifications of an original contract that effectively change the provisions of the contract without adding new provisions. Either the
Company or its client may initiate change orders. They may include changes in specifications or design, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Claims are amounts in excess of the agreed
contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price,
or other causes of unanticipated additional contract costs.

Change orders and claims occur when changes are experienced once contract
performance is underway. Change orders are sometimes documented and terms of such change orders are agreed with the client before the work is performed. Sometimes circumstances require that work progresses before agreement is reached with the
client. Costs related to change orders and claims are recognized when they are incurred. Change orders and claims are included in total estimated contract revenue when it is probable that the change order or claim will result in a bona fide addition
to contract value that can be reliably estimated. No profit is recognized on claims until final settlement occurs. This can lead to a situation where costs are recognized in one period and revenues are recognized when client agreement is obtained or
claims resolution occurs, which can be in subsequent periods.

##### Table of Contents

The Company has contracts with the U.S. government that contain provisions requiring compliance with the
U.S. Federal Acquisition Regulations (FAR). These regulations are generally applicable to all of its federal government contracts and are partially or fully incorporated in many local and state agency contracts. They limit the recovery
of certain specified indirect costs on contracts subject to the FAR. Cost-plus contracts covered by the FAR provide for upward or downward adjustments if actual recoverable costs differ from the estimate billed under forward pricing arrangements.
Most of its federal government contracts are subject to termination at the convenience of the client. Contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination.

Federal government contracts which are subject to the FAR and some state and local governmental agencies require audits, which are performed for the most
part by the Defense Contract Audit Agency (DCAA). The DCAA audits the Companys overhead rates, cost proposals, incurred government contract costs, and internal control systems. During the course of its audits, the DCAA may question
incurred costs if it believes the Company has accounted for such costs in a manner inconsistent with the requirements of the FAR or Cost Accounting Standards (CAS) and recommend that its U.S. government corporate administrative
contracting officer disallow such costs. Historically, the Company has not experienced significant disallowed costs as a result of such audits. However, the Company can provide no assurance that the DCAA audits will not result in material
disallowances of incurred costs in the future.



|(s) | Share-Based Compensation
|--- | ------------------------

The Company
follows the provisions of Statement of Financial Accounting Standards (SFAS) No. 123(R), Share-Based Payment. The Company uses the Black-Scholes option pricing model to measure the estimated fair value of the options under
SFAS No. 123(R). The compensation expense, less forfeitures, is being recognized over the service period on a straight-line basis. The Companys policy is to use newly issued shares to satisfy the exercise of stock options.



|(t) | Advertising Costs
|--- | -----------------

Advertising costs are
expensed as incurred. Such expenses for the years ended December 31, 2007, December 30, 2006 and December 31, 2005, are approximately $666,000, $450,000 and $193,000, respectively.



|(u) | Earnings per Share
|--- | ------------------

Basic earnings per
common share and diluted earnings per common share are presented in accordance with SFAS No. 128, Earnings per Share. Basic earnings per common share has been computed using the weighted-average number of shares of common stock
outstanding during the year. Diluted earnings per common share incorporates the incremental shares issuable upon the assumed exercise of stock options and warrants using the treasury stock method.

Dilutive stock options and warrants increased average common shares outstanding by approximately 4,667,000, 1,249,000 and 2,250,000 shares for the years
ended December 31, 2007, December 30, 2006 and December 31, 2005, respectively.

Options to purchase 681,904 shares,
25,000 shares and 1,563,000 shares of the Companys common stock were not included in the calculation of common shares outstanding for the years ended December 31, 2007, December 30, 2006 and December 31, 2005, respectively,
because they were anti-dilutive.

Warrants to purchase 13,600,000 shares of the Companys common stock and an underwriters
option to purchase 300,000 units consisting of one share of the Companys common stock and two warrants to purchase shares of the Companys common stock were not included in the calculation of common shares outstanding for the year ended
December 30, 2006 because they were anti-dilutive.

|(v) | Recent Accounting Pronouncements

FASB Statement
No. 157

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which became effective on
January 1, 2008. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. Implementation of SFAS No. 157 will
not have a material impact on our financial statements.

FASB Staff Position No. 157-1

In February 2008, the FASB issued FASB Staff Position (FSP) No. 157-1, Application of FASB Statement No. 157 to FASB Statement
No. 13 and Its Related Interpretive Accounting Pronouncements That Address Leasing Transactions, which will become effective for the Company on January 1, 2009. This FSP excludes FASB Statement No. 13, Accounting for
Leases, and its related interpretive accounting pronouncements from the provisions of SFAS No. 157. Implementation of this standard is not expected to have a material effect on our financial statements.

FASB Staff Position FAS No. 157-2

In
February 2008, the FASB issued FSP No. 157-2,Effective Date of FASB Statement No. 157,which delays the Companys January 1, 2008 effective date of SFAS No. 157 for all nonfinancial assets and nonfinancial
liabilities, except those recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), until January 1, 2009. Implementation of this standard is not expected to have a material effect on our
financial statements.

FASB Statement No. 159

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial LiabilitiesIncluding an amendment of FASB Statement No. 115,which became
effective for the company on January 1, 2008. This standard permits companies to choose to measure many financial instruments and certain other items at fair value and report unrealized gains and losses in earnings. Such accounting is optional
and is generally to be applied instrument by instrument. Implementation of SFAS No. 159 will not have a material effect on our financial statements.

FASB Statement No. 141 (revised 2007)

In December 2007, the FASB issued SFAS No. 141(revised 2007),
Business Combinations, which will become effective for business combination transactions having an acquisition date on or after January 1, 2009. This standard requires the acquiring entity in a business combination to recognize the
assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date to be measured at their respective fair values. The Statement requires acquisition-related costs, as well as restructuring costs the
acquirer expects to incur for which it is not obligated at acquisition date, to be recorded against income rather than included in purchase-price determination. It also requires recognition of contingent arrangements at their acquisition-date fair
values, with subsequent changes in fair value generally reflected in income.

FASB Statement No. 160

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51,which will become effective for the Company January 1, 2009, with retroactive adoption of the Statements presentation and disclosure requirements for existing minority interests. This standard will require ownership interests in
subsidiaries held by parties other than the parent to be presented within the equity section of the consolidated balance sheet but separate from the parents equity. It will also

##### Table of Contents

require the amount of consolidated net income attributable to the parent and the noncontrolling interest to be clearly identified and presented on the face
of the consolidated income statement. Certain changes in a parents ownership interest are to be accounted for as equity transactions and when a subsidiary is deconsolidated, any noncontrolling equity investment in the former subsidiary is to
be initially measured at fair value. We do not anticipate the implementation of SFAS No. 160 will significantly change the presentation of our consolidated income statement or consolidated balance sheet.

Staff Accounting Bulletin No. 110

In December
2007, the SEC released Staff Accounting Bulletin (SAB) No. 110 which indicates that the staff will continue to accept, under certain circumstances, the use of the simplified method in developing an estimate of the expected term for
plain vanilla options in accordance with SFAS No. 123(R), Share-Based Payment. The Company has no historical data on which to base its estimate (see Note 13 to the Companys consolidated financial statements) and,
accordingly, it will continue to use the simplified method until such historical data becomes available.

Note 3Acquisitions

KJM & Associates, Ltd.

On
May 10, 2007, the Company acquired all of the common stock of KJM & Associates, Ltd. (KJM). KJM provides project management and project controls services primarily for the transportation and education markets. KJM is
headquartered in Bellevue, Washington and provided the Companys Project Management Group with new and expanded geographic coverage in Washington, Oregon, California, Arizona, Texas and New York.

The Company paid $9,350,000 consisting of $8,350,000 in cash plus 136,593 shares of restricted common stock of the Company (the Restricted
Shares) initially valued at $1,000,000. The Restricted Shares were valued based on the average closing price of the Companys common stock for the 10 trading days prior to the closing date. The Restricted Shares will be held in escrow for
one year as security for any indemnification obligations of KJMs selling stockholder. Since the Restricted Shares are subject to forfeiture, they will not be considered outstanding for accounting purposes until the end of the contingency
period, at which time the fair value of those shares actually distributed will be accounted for as additional purchase consideration. Substantially all of KJMs operations were integrated into Hill on September 1, 2007.

The acquisition was accounted for under the purchase method of accounting, effective as of May 1, 2007, and accordingly, the results of operations
and cash flows of KJM have been included in the accompanying Consolidated Financial Statements for the period subsequent to the effective date. At December 31, 2007, the total purchase price, including acquisition expenses of $202,000, but
excluding the Restricted Shares, which constitute contingent consideration, was $8,552,000. The following table summarizes the allocation of the purchase price based on the fair value of the assets acquired and liabilities assumed as of the
acquisition date (in thousands):

The acquired intangibles have a weighted average life of 9.1 years. The intangible assets consist of a
customer related intangible of $2,854,000 with a 10 year life, a contract intangible of $366,000 with a four year life, a trade name intangible of $107,000 with a life of two years and a covenant-not-to-compete of $18,000 with a three year life.
Goodwill has been allocated to the Project Management segment and is expected to be deductible for income tax purposes. The results of operations of KJM were not material to the Companys consolidated statement of earnings.

James R. Knowles (Holdings) PLC

On
August 31, 2006, Hill International S.A., a wholly-owned subsidiary of the Company, acquired approximately 96.5% of the outstanding shares of James R. Knowles (Holdings) PLC (Knowles), a construction claims consulting and dispute
resolution company with 36 offices worldwide, headquartered in Daresbury, United Kingdom, for a price of 33 pence (or approximately $0.62 at the exchange rate current as of the date of the acquisition) per share in cash. In accordance with
applicable law, Hill International S.A. compulsorily acquired the remaining 3.5% of the outstanding shares of Knowles during 2006. The consideration paid by Hill International S.A. for all of the outstanding shares of Knowles was approximately
$13,000,000, excluding direct acquisition costs.

The following table sets forth the determination of the consideration paid for Knowles at
the date of acquisition (in thousands):



|                               |  |   |       
|------------------------------ |  | - | ------
|Cash                           |  | $ | 13,017

|                               |  |   |       

The transaction was accounted for as a purchase and, accordingly, the purchase price was allocated
to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of the acquisition. A detailed valuation using the guidance as set forth in SFAS No. 141, Business Combinations, was performed
to determine the fair value of the intangible assets and goodwill acquired in the acquisition.

The following table sets forth the final
allocation of the purchase price (in thousands):

Included in accrued expenses are exit costs and involuntary termination costs related to the
Companys acquisition of Knowles. The Solicitors business of Knowles, consisting of Knowles Lawyers Limited (KLL) and Sydney Lawyers, was identified during the pre-acquisition evaluation as a business that would be divested. The
remaining staff at KLL was made redundant and the Company incurred involuntary employee termination benefits aggregating approximately £76,000 (approximately $148,000 at conversion rate on March 20, 2007). The KLL business had an
operating loss of £645,000 (approximately $1,255,000 at conversion rate on March 20, 2007, including the $148,000 of involuntary employee termination benefits described above), during the period of September 1, 2006 through
December 31, 2006. The operating losses have been accounted for as additional acquisition costs during the fourth quarter of 2006 in accordance with EITF 95-3 Recognition of Liabilities in Connection with a Purchase Business Combination.
An agreement was reached in December 2006 to acquire the remaining 25% of the minority interest of Knowles Law Ltd. for an agreed amount of £80,000. As a result of this transaction total goodwill of £134,000 (approximately $261,000 at
conversion rate on March 20, 2007) was written off and recorded as additional purchase price. The Company also accrued £149,000 (approximately $290,000 at conversion rate on March 20, 2007) for involuntary termination costs of one
other employee.

The customer list and relationships intangible assets have a weighted average life of 10 years and the trade name has a
weighted average life of 3 years; such intangibles have an aggregate weighted life of 9.6 years. Goodwill has been allocated to the Construction Claims segment and is not expected to be deductible for income tax purposes.

The operating results for Knowles are included in the accompanying consolidated statements of earnings from the date of the acquisition.

The following unaudited pro forma information assumes the Knowles acquisition had occurred on January 1, 2006. The pro forma information, as
presented below, is not necessarily indicative of the results that would have been obtained had the Knowles acquisition occurred on that date, nor is it necessarily indicative of the Companys future results:

The present value of the anticipated payments was calculated by discounting back to the acquisition date
the future payments using an 8% imputed interest cost (the Companys approximate average borrowing cost at the acquisition date). The discounted price was then converted into U.S. dollars using an exchange rate of approximately $1.78/£1,
the exchange rate on the date of the acquisition.

The purchase price of the outstanding stock, not including liabilities assumed, was in
the form of future payments as follows:

Note 7Goodwill

The Company follows the provision of SFAS No. 142,Goodwill and Other Intangible Assets. SFAS No. 142 requires an annual impairment test for goodwill and intangible assets with indefinite lives. Under
SFAS No. 142, the first step of the impairment test requires that the Company determine the fair value of each reporting unit, and compare the fair value to the reporting units carrying amount. To the extent a reporting units
carrying amount exceeds its fair value, an indication exists that the reporting units goodwill may be impaired and the Company must perform a second more detailed impairment assessment. The second impairment assessment involves allocating the
reporting units fair value to all of its recognized and unrecognized assets and liabilities in order to determine the implied fair value of the reporting units goodwill as of the assessment date. The implied fair value of the reporting
units goodwill is then compared to the carrying amount of goodwill to quantify an impairment charge as of the assessment date.

Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the businesses, the useful life
over which cash flows will occur, and determination of the Companys weighted average cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or conclusions on goodwill impairment
for each reporting unit. The Company performed its annual impairment test effective July 1, 2007 and noted no impairment for either of its reporting units. In the future, the Company will continue to perform the annual test during its fiscal
third quarter unless events ore circumstances indicate an impairment may have occurred before that time.

The additions to goodwill in 2006
relate to the acquisitions of Pickavance and Knowles (see Note 3). The additions to goodwill in 2007 relate to the finalization of the Knowles purchase price allocation ($2,378,000), acquisition of the minority interest of a Knowles
subsidiary ($221,000), and the acquisition of KJM ($2,525,000),. The following table summarizes the changes in the Companys carrying value of goodwill during 2006 and 2007:

On December 18, 2006, the Company and LaSalle entered into a loan and security agreement (the
Credit Facility), which was amended on October 15, 2007 to provide for up to $35,000,000 to be made available to the Company on a revolving basis. The Credit Facility provides for a letter of credit sub-facility of $20,000,000. The
Credit Facility is secured by all of the assets of the Company, including, without limitation, its accounts receivable, equipment, securities, financial assets and the proceeds of the foregoing, as well as by a pledge of 66.67% of the outstanding
capital stock of the following subsidiaries of the Company: Hill International S.A., Hill International (UK) Ltd., Hill International (Middle East) Ltd. and James R. Knowles (Holdings) Ltd. At December 31, 2007, the Company had $7,658,000 in
outstanding letters of credit which reduced availability under the Credit Facility.

The Credit Facility is for a term extending until
January 1, 2011. The Credit Facility provides for LIBOR loans and prime rate loans, payable at margins above either LaSalles prime rate or LIBOR based on the Companys ratio of total debt to EBITDA ranging from zero to 50 basis
points above LaSalles prime rate or 150 to 262.50 basis points above LIBOR. At December 31, 2007 the applicable margins were zero basis points above LaSalles prime rate of 7.125% and 150 basis points above LIBOR of 5.50% (or 7.00%).
At December 30, 2006, the applicable margins were 25 basis points above LaSalles prime rate of 8.25% (or 8.50%), and 225 basis points above LIBOR of 5.25% (or 8.00%). The Credit Facility contains covenants with respect to the
Companys minimum net worth, total debt to EBITDA ratios, fixed charge coverage ratios and billed accounts receivable to

Note 13Stock Options

The 2006 Employee Stock Option Plan (the Plan) covers 1,140,000 shares of the Companys common stock. Under its terms, directors,
officers and employees of the Company and its subsidiaries are eligible to receive non-qualified and incentive stock options. Options granted to non-employee directors vest immediately and have a seven year contractual term. Options granted to
officers and employees vest over five-years and have a ten year contractual term. Generally, each option has an exercise price equal to the closing quoted market price of a share of the Companys common stock on the date of grant. For grants of
incentive stock options, if the grantee owns, or is deemed to own, 10% or more of the total voting power of the Company, then the exercise price shall be 110% of the closing quoted market price on the date of grant. Options that are forfeited or
expire are available for future grants. At December 31, 2007, a total of 285,000 shares of common stock were reserved for future issuance under the Plan.

The Black-Scholes option valuation model was used to estimate the fair value of the options under SFAS No. 123(R) for 2007, 2006 and 2005. The following table summarizes the fair value of options granted during
2007, 2006 and 2005 and the assumptions used to estimate the fair value (no dividends were assumed):

The expected term of the options is estimated based on the simplified method as
permitted by SAB No. 107. Expected volatility was calculated using the average historical volatility of similar public companies. The risk-free interest rate is based on U.S. Treasury yields for securities in effect at the time of grants with

At December 31, 2007, total unrecognized compensation cost related to non-vested options was
$1,823,000 and will be recognized over the remaining weighted-average service period of 4.2 years.

Note 14Warrants

Following Arpeggios initial public offering, there were 13,600,000 Redeemable Common Stock Purchase Warrants (the Warrants) issued and
outstanding. Each Warrant entitled the holder to purchase from the Company one share of common stock at an exercise price of $5.00 commencing on June 28, 2006 (the completion of the Hill and Arpeggio merger) and expiring on June 23,
2008 (four years from the effective date of Arpeggios Initial Public Offering). The Warrants were redeemable at a price of $.01 per Warrant upon 30 days notice, only in the event that the closing market price of the common stock was at least
$8.50 per share for any 20 trading days within a 30 trading day period, ending on the third day prior to the date on which notice of redemption is given. On October 23, 2007, the Company notified the warrant holders of its intention to redeem
the warrants on November 23, 2007. As of November 23, 2007, all but 24,399 warrants had been exercised. The Company redeemed the remaining warrants. During 2007, the Company received $67,878,000 in connection with the exercise of warrants.

In connection with its Initial Public Offering, Arpeggio issued an option for $100 to representatives of the underwriters to purchase
300,000 Units at an exercise price of $9.90 per Unit. Each Unit consists of one share of the Companys common stock and warrants to purchase two shares of the Companys common stock at an exercise price of $6.25 per share. In October and
November 2007, the holders exercised on a cashless basis their options and the underlying warrants resulting in the issuance of 217,510 shares of the Companys common stock.

Note 15Certain Transactions with Stockholder

Prior to the merger with Arpeggio in June 2006,
from time to time, the Company made cash advances to Irvin E. Richter, its principal stockholder. These advances were non-interest bearing, had no set repayment term

and were classified in Stockholders Equity in the Consolidated Balance Sheets. The entire amount due from the Companys principal stockholder of
$1,008,000 was repaid to the Company on April 21, 2006. The Company has adopted a policy that no longer allows executive officer advances or loans.

Mr. Richter also had a personal loan of $1,850,000 with a bank. As collateral for this loan, on August 10, 2004, the Company assigned $1,850,000 of potential life insurance proceeds to the bank which would
be payable to us upon Mr. Richters death. In addition, on April 5, 2005 the Company pledged, in the event of a default, to buy back from the lender 500,000 shares of our common stock which had been pledged by Mr. Richter as
collateral for the loan. The loan was repaid in June 2006.

Note 16Selling, General and Administrative Expenses

Also included in selling, general and administrative expenses in the consolidated statements of earnings is bad debt expense of $2,271,000, $886,000 and
$605,000 for the fiscal years ended 2007, 2006 and 2005, respectively.

Note 17Income Taxes

The effective tax rates for the years ended December 31, 2007, December 30, 2006 and December 31, 2005 were 16%, 23% and 37%
respectively. The Companys effective tax rate continues to decline becausea greater portion of its profit comes from foreign operations which are taxed at lower rates, if at all. It is anticipated that the Companys effective tax
rate may fluctuate in the future due to the mix of foreign and domestic pre-tax earnings.

Income before provision for income taxes is
allocated as follows:

In assessing the realizability of deferred tax assets, management considers whether it is more likely
than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences
become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income in making this assessment. Based upon the level of historical taxable income and projections for future taxable income
over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, with the exception of foreign net operating losses. The
amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced.

At December 31, 2007 and December 30, 2006, there were approximately $4,237,000 and $6,800,000 of gross foreign net operating loss
carryforwards, respectively. The majority of these net operating loss carryforwards have an unlimited carryforward period. A valuation allowance of $1,117,000 and $392,000 was recorded at December 31, 2007 and December 30, 2006,
respectively, in relation to the foreign net operating losses and a deferred asset for foreign exchange losses.

The Company has made no
provision for U.S. taxes on $26,400,000 of cumulative earnings of foreign subsidiaries as those earnings are intended to be reinvested for an indefinite period of time. Upon distribution of these earnings in the form of dividends or otherwise, the
Company may be subject to U.S. income taxes and foreign withholding taxes. It is not practical, however, to estimate the amount of taxes that may be payable on the eventual repatriation of these earnings.

With respect to compensation expense under SFAS No. 123(R), the Company reduced the current federal and state income tax payable by $60,000 and
$1,804,000 at December 31, 2007 and December 30, 2006, respectively, for deductible stock option expenses that were reflected as income by certain employees in 2006.

In July 2006, the FASB issued FASB Interpretation No. (FIN) 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB
Statement No. 109, which provides criteria for the recognition, measurement, presentation and disclosure of uncertain tax positions. The Company adopted the provisions of FIN 48 on December 31, 2006, the first day of our fiscal year.
As a result of the implementation of FIN 48, the Company has analyzed filing positions in all of the federal, state and foreign filing jurisdictions where it is required to file income tax returns, as well as all open years in those jurisdictions.
In this regard, an uncertain tax position represents the Companys expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for
financial reporting purposes. As a result of this review, the Company concluded that at this time there are no uncertain tax positions which would require a cumulative effect adjustment to retained earnings.

The following table indicates the changes to the Companys uncertain tax positions for the year ended December 31, 2007 including interest and
penalties:

Of the balance noted above, $2,506,000 is included in Income taxes payable and
$3,237,000 is included in Other liabilities in the consolidated balance sheet.

The Company files income tax returns in the
U.S. federal jurisdiction and in various states and foreign jurisdictions. As a result of its acquisition of Knowles, the Company has an ongoing audit for two Knowles affiliates for the years ended in 2000 through 2005. Due to current negotiations
with Inland Revenue, the Company has

decided to reduce the FIN 48 liability due to a proposed settlement agreement. The Company generally is no longer subject to U.S. federal, state or foreign
examinations by tax authorities for tax years prior to 2004.

The Companys policy is to record income tax related interest and
penalties in income tax expense. At December 31, 2007, the Company had accrued $2,500,000 for potential interest and penalties.

The
Companys income tax returns are based on calculations and assumptions that are subject to examinations by the Internal Revenue Service and other tax authorities. While the Company believes it has appropriate support for the positions taken on
its tax returns, the Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of its provision for income taxes. As part of its assessment of
potential adjustments to its tax returns, the Company increases its current tax liability to the extent an adjustment would result in a cash tax payment or decreases its deferred tax assets to the extent an adjustment would not result in a cash tax
payment. The Company continually assesses the likelihood and amount of potential adjustments and adjusts the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a revision become
known.

Note 18Commitments and Contingencies

Litigation

On September 23, 1996, William Hughes General Contractors, Inc. (Hughes) filed a complaint in
the Superior Court of New Jersey, Law Division, Gloucester County, against the Monroe Township Board of Education, the Company and other parties, alleging breach of contract and other causes of action in connection with its performance of a
construction project for Monroe Township, seeking in excess of $3,500,000 in damages. Monroe Township, which had terminated Hughes from the construction project prior to the commencement of the litigation on the basis of Hughes performance,
made a cross claim against the Company and other parties for contribution and indemnification. Monroe Township is seeking approximately $89,000 in damages from the Company, in addition to an indemnification for Hughes claims. In relation to
the Hughes claims, a claim was made against the Company by Fidelity and Deposit Company of Maryland (F&D). F&D is claiming damages in the range of $425,000 to $470,000. The F&D claim is being defended by the New Jersey
Professional Liability Insurance Guarantee Association and losses are covered up to $300,000. The Company believes that the claims of Hughes, Monroe Township and F&D are without merit and, based on the Companys current understanding and
evaluation of the relevant facts and circumstances, no accruals have been made for any of these claims because the Company considers the chance of loss to be remote.

On September 22, 1999, Wartsila NSD North America, Inc. filed a complaint against the Company in the United States District Court for the District of New Jersey. Wartsila alleged negligence, breach of contract
and fraud against the Company in connection with plaintiffs hiring of a former Company employee and sought damages in excess of $7,300,000. A jury verdict was rendered on March 6, 2006. The jury found that the Company was negligent and
breached the contract with plaintiff but that the Company did not commit fraud. The jury awarded damages of approximately $2,000,000. The Company filed a Motion to Mold the Verdict and to Enter Judgment consistent with the parties contract
which contains a limitation of liability clause which limits the Companys liability, absent fraud, to direct damages. In connection with the Arpeggio and Hill merger described in Note 2 to the consolidated financial statements, stockholders of
the pre-merger Hill International, Inc. had escrowed a total 1,450,000 shares of the Companys stock to satisfy non-tax indemnification claims by the Company arising out of this and certain other matters. Liability in this matter, if any, will
ultimately be satisfied from such escrowed shares under the terms of an escrow agreement. On June 28, 2006 the Court denied the Companys motion and the Company subsequently filed a Notice of Appeal on July 26, 2006 with the Third
Circuit Court of Appeals. The Company has posted a letter of credit securing the judgment plus pre- and post-judgment interest in the amount of $3,350,000. The Company also recorded a corresponding accrued liability in the amount of $3,350,000
included in Accrued liabilities on the Companys consolidated balance sheet at

##### Table of Contents

December 31, 2007 and December 30, 2006. From the shares held in escrow, a total of 451,665 shares representing $3,350,000 has been allocated at
this time to the Company for satisfaction of the judgment and will be placed in treasury stock in the event the judgment is ultimately paid.

On May 28, 2004, Sims Group, Inc. (Sims) filed a Demand for Arbitration with the American Arbitration Association alleging breach of contract against the Company. The plaintiff was a subcontractor to the Company and sought
the alleged contract balance owed of approximately $1,300,000. The Company filed a counterclaim on July 2, 2004 alleging fraud and breach of contract. This matter was arbitrated during April 2006 and an arbitration award was issued on
June 28, 2006 awarding Sims $1,250,000 plus costs of $33,000. The Company had accrued a liability of $772,000 related to this matter prior to September 30, 2005. In connection with the Arpeggio and Hill merger described in Note 2 to the
consolidated financial statements, stockholders of the pre-merger Hill International, Inc. had escrowed 1,450,000 shares of the Companys stock to satisfy non-tax indemnification claims by the Company arising out of this and certain other
matters. Liability in this matter in excess of amounts accrued as of September 30, 2005 was to be satisfied from such escrowed shares. In October 2006, the Company made a payment of approximately $1,300,000 to claimant to satisfy this matter in
full. From the shares held in escrow, a total of 69,540 shares representing $515,777 were released to the Company on July 16, 2007 for satisfaction of the judgment amount in excess of the amount accrued and have been placed in treasury.

On May 23, 2007, Hill filed a Demand for Arbitration with the American Arbitration Association alleging breach of contract, breach of
the covenant of good faith and fair dealing, unjust enrichment and/or fraudulent inducement against Bachmann Springs Holdings, LLC and Thomas Bachmann (hereinafter, collectively Bachmann). Hill was hired by Bachmann to provide
professional support services and is demanding payment of invoices in the amount of $634,904, plus accrued interest. On October 17, 2007, Bachmann filed a counterclaim with the American Arbitration Association alleging fraud and breach of
contract and seeking damages in the amount of $8,600,000. The Company believes that Bachmanns counterclaim is without merit and, based on the Companys current understanding and evaluation of the relevant facts and circumstances, no
accruals have been made for this claim because the Company considers the chance of loss to be remote.

General Litigation

From time to time, the Company is a defendant or plaintiff in various legal actions which arise in the normal course of business. As such the Company is
required to assess the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of the provision required for these commitments and contingencies, if any, which would be
charged to earnings, is made after careful analysis of each matter. The provision may change in the future due to new developments or changes in circumstances. Changes in the provision could increase or decrease the Companys earnings in the
period the changes are made. It is the opinion of management, after consultation with legal counsel, that the ultimate resolution of these matters should not have a material adverse effect on the Companys financial condition, results of
operations or cash flows.

Off-Balance Sheet Arrangements

As discussed above, the Company has posted a letter of credit securing a judgment plus pre- and post-judgment interest in the amount of $3,350,000.

The Company enters into agreements with banks for the banks to issue bonds to clients or potential clients for three separate purposes as follows:



|(1) | Certain of the Companys subsidiaries (Hill International S.A., Hill International (UK) Ltd. and Hill International (Middle East) Ltd.) have entered into
contracts for the performance of construction management services which provide that the Company receive advance payment of some of the management fee from the client prior to commencement of the construction project. However, the clients require a
guarantee of service performance in the form of an advance payment bond. These bonds are

| | evidenced by Letters of Guarantee issued by the subsidiaries banks in favor of the clients. In some cases these clients also require a parent company
guarantee.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | The Company may also enter into certain contracts which require a performance bond to be issued by a bank in favor of the client for a portion of the value of the contract. These
bonds may be exercised by the client in instances where the Company fails to provide the contracted services.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Certain clients may require bonds as part of the bidding process for new work. The bid bonds are provided to demonstrate the financial strength of the companies seeking the work and
are usually outstanding for short periods. If the bid is rejected the bond is cancelled and if the bid is accepted the Company may be required to provide a performance bond.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The maximum potential future payment under these arrangements at December 31, 2007 was $28,418,000.

Cash held in restricted accounts as collateral for the issuance of performance and advance payment bonds at December 31, 2007 and December 30,
2006 were $5,057,000 and $6,882,000, respectively.

Note 19Operating Leases

The Company has numerous operating leases which have various expiration dates through May 2016. Rent expense was approximately $6,511,000, $3,955,000 and
$2,900,000 for the fiscal years ended December 31, 2007, December 30, 2006 and December 31, 2005, respectively, which is included in selling, general and administrative expenses in the consolidated statements of earnings. The
Company is required to pay property taxes, utilities and other costs related to several of its leased office facilities.

At
December 31, 2007, approximate future minimum payments under these leases that have remaining non-cancelable lease terms in excess of one year are as follows:

In 2007, the Company revised the method by which it allocates revenue to geographic areas for
project management contracts. The Company now allocates revenue based on the site of the actual project which provides a more accurate portrayal of the areas in which the Company operates. Previously, the Company allocated revenue based on the
location of the customer. For construction claims contracts, the Company allocates revenue based on the location of the office performing the work. The amounts for 2006 and 2005 have been revised to reflect the new method.

Note 23Subsequent Events

Acquisition of Gerens Management Group, S.A.

On February 15, 2008, Hill International, S.A., the Companys wholly-owned subsidiary, acquired 60% of the outstanding capital stock of Gerens Management Group, S.A. (Gerens), a
Spanish-headquartered firm that provides project management services on major construction projects throughout Spain as well as in Western Europe and Latin America. The consideration paid by Hill International S.A. was 10,800,000 ($15,800,000)
in cash. The remaining minority stockholders of Gerens, who own 40% of the company, consist of Gerens Managing Director as well as a group of major Spanish savings banks. Gerens, which has about 250 employees, immediately changed its name to
Gerens Hill International, S.A.

Gerens is headquartered in Madrid and has additional offices in Barcelona and Cancun, Mexico. The company
has managed the construction of major projects in various sectors, including residential, commercial, healthcare, retail and leisure, infrastructure, and hotels and resorts. Gerens brings together extensive knowledge of the Spanish market and
worldwide experience in the management and control of complex design and construction processes offering their clients project management and independent technical consultancy services. In 2007, Gerens had unaudited total revenues of approximately
21,000,000 ($30,600,000). At December 31, 2007, Gerens had total backlog of approximately 27,300,000 ($39,900,000).

In
connection with the acquisition, Gerens shareholders, including Hill International S.A., entered into an agreement whereby the minority shareholders have a right to compel Hill International S.A. to purchase any or all of their shares during
the period from March 31, 2010 to March 31, 2020. Hill International S.A. also has the right to compel the minority shareholders to sell any or all of their shares during the period from March 31, 2011 to March 31, 2021. The
purchase price for such shares shall be the greater of (a) 18,000,000 increased by the General Price Index (capped at 3.5% per annum) or (b) ten times the companys earnings before interest and income taxes for the prior
fiscal year, multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of the purchase. Such amount may be increased by increases in equity subsequent to the acquisition date, and can be
paid in cash or shares of our common stock at the option of the sellers.

Acquisition of John Shreeves Holdings Ltd.

On January 7, 2008, the Company acquired John Shreeves Holdings Ltd. and its operating subsidiary John Shreeves &
Partners Ltd. (collectively Shreeves), a London-based firm that provides project management and cost consultancy services on primarily private-sector projects throughout the United Kingdom. The acquired business will continue to operate
under the Shreeves brand name until its operations have been consolidated with Hills. For its last fiscal year, ended April 30, 2007, Shreeves had revenues of approximately £2.4 million ($4,800,000). Total consideration
amounted to £1,850,000 ($3,700,000) consisting of a cash payment of £1,650,000 ($3,300,000) on the date of closing and a cash payment of £200,000 ($400,000) payable six months after the closing date. The results of operations of
Shreeves are not material to the consolidated results of operations of the Company.

Transfer to New York Stock Exchange

On February 22, 2008, the Companys common stock commenced trading on the New York Stock Exchange under the ticker symbol HIL.

FIN 48 Reversal

In February
2008, the Company realized a tax benefit of $2,506,000 upon the filing of certain income tax returns. This amount will reduce income tax expense in the first quarter of 2008.

Report of Independent Registered Public Accounting Firm

To the Stockholders of

Hill International, Inc. and Subsidiaries

We have audited the accompanying consolidated balance sheets of Hill International, Inc. and Subsidiaries as of December 31, 2007 and
December 30, 2006, and the related consolidated statements of earnings, stockholders equity, comprehensive income and cash flows for each of the years in the three-year period ended December 31, 2007. Our audits also included the
financial statement schedule included in Item 15. These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits. We
did not audit the December 31, 2005 financial statements of Hill International (UK) Limited, wholly owned subsidiary, which statements reflect revenues constituting 9 percent of the related consolidated revenues. Those statements were audited
by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for Hill International (UK) Limited is based solely on the report of the other auditor.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over
financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Companys internal control over financial reporting. Accordingly we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the financial statements referred to above present fairly, in all material
respects, the financial position of Hill International, Inc. and Subsidiaries as of December 31, 2007 and December 30, 2006, and the consolidated results of their operations and cash flows for each of the years in the three-year period
ended December 31, 2007 in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a
whole, presents fairly in all material respects the information set forth therein.

As discussed in Notes 2 and 17, the Company changed its
method of accounting for uncertain tax positions effective December 31, 2006.

|Item 9A (T). | Controls and Procedures
|------------ | -----------------------

(a)
Managements Annual Report on Internal Control over Financial Reporting.

Under Section 404 of the Sarbanes-Oxley Act of
2002, management is required to assess the effectiveness of the Companys internal control over financial reporting as of the end of each fiscal year and report, based on that assessment, whether the Companys internal control over
financial reporting is effective.

The Companys management is responsible for establishing and maintaining adequate internal control
over financial reporting. The Companys internal control over financial reporting is a process designed to provide reasonable assurance of the reliability of its financial reporting and of the preparation of its financial statements for
external reporting purposes, in accordance with U.S. generally accepted accounting principles.

The Companys internal control over
financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and disposition of assets; (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with the authorization of its
management and directors; and (3) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use, or disposition of the Companys assets that could have a material effect on its financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures included in such
controls may deteriorate.

##### Table of Contents

The Companys management has assessed the effectiveness of the Companys internal control over
financial reporting as of December 31, 2007. In making this assessment, the Company used the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal
ControlIntegrated Framework. These criteria are in the areas of control environment, risk assessment, control activities, information and communication, and monitoring. The Companys assessment included extensive documenting,
evaluating and testing the design and operating effectiveness of its internal controls over financial reporting. Based on the Companys processes and assessment, as described above, management has concluded that, as of December 31, 2007,
the Companys internal control over financial reporting was effective.

This annual report does not include an attestation report of
the Companys registered public accounting firm regarding internal control over financial reporting. Managements report was not subject to attestation by the Companys registered public accounting firm pursuant to temporary rules of
the Securities and Exchange Commission that permit the Company to provide only managements report in this Annual Report.

(b)
Changes in Internal Control over Financial Reporting

During the quarter ended December 31, 2007, there were no changes in our
internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
