              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1999
                                   (UNAUDITED)

1.       SUMMARY OF PRESENTATION - The condensed consolidated financial
         statements included herein have been prepared by AHL Services, Inc.
         ("AHL" or the "Company"), without audit, pursuant to the rules and
         regulations of the Securities and Exchange Commission. Certain
         information and footnote disclosures normally included in financial
         statements prepared in accordance with generally accepted accounting
         principles have been condensed or omitted pursuant to such rules and
         regulations, although the Company believes that the disclosures are
         adequate to make the information not misleading. In the opinion of
         management, the condensed consolidated financial statements contain all
         adjustments necessary to present fairly the financial position of the
         Company as of June 30, 1999, the results of its operations for the
         three and six months ended June 30, 1999 and 1998 and the results of
         its cash flows for the six months ended June 30, 1999 and 1998. All
         such adjustments are of a normal recurring nature. The results of
         operations for the three and six months ended June 30, 1999 are not
         necessarily indicative of the results to be expected for the year ended
         December 31, 1999. For further information, refer to the consolidated
         financial statements and footnotes thereto for the year ended December
         31, 1998 included in the Company's annual report on Form 10-K for such
         period.

2.       ACQUISITIONS AND DIVESTITURES - On December 28, 1998, the Company
         acquired Unicco Security Services, Inc. ("Unicco"), a subsidiary of
         USC, Inc., for $12 million in cash. Unicco is an access control and
         security services company operating under long-term contracts with a
         geographic focus primarily in the northeastern United States and
         Chicago. Unicco had annual revenues of over $50 million in 1998.

         On April 30, 1999, the Company acquired Professional Inventory
         Management and Merchandising Services Corporation ("PIMMS") for $65
         million in cash plus potential contingent consideration. PIMMS is
         headquartered in Minneapolis and provides outsourced in-market
         merchandising services to major consumer product manufacturers and
         large retail chains. PIMMS had annual revenues of over $40 million in
         1998.

         Also on April 30, 1999, AHL acquired MM Zeitarbeit GmbH ("MM"), a
         German operational support staffing services provider, for $1.75
         million in cash. MM provides outsourced light industrial services in
         the Bavaria region of Germany, operating within the same geographic
         region as TUJA, a light industrial services company acquired by AHL
         during 1998. Combined with the TUJA operations, MM creates greater
         density for AHL within the Bavaria region, and creates a broader base
         of clients for future growth. MM's 1998 revenues were over $3 million.

         On June 30, 1999, the Company acquired Excel Resourcing Limited
         ("Excel"), a small, fast-growing industrial staffing company in the UK,
         for $3 million in cash. Excel had annual revenues of over $7 million in
         1998.

         The results of operations of these acquisitions have been included in
         the attached condensed consolidated financial statements included
         herein since the applicable date of acquisition. These acquisitions
         were accounted for using the purchase method of accounting. As a
         result, the purchase prices have been allocated to the assets acquired,
         including intangibles, based on their respective fair values. The
         purchase price allocations are preliminary and subject to adjustment.

         On June 30, 1999, the Company sold its UK bus transportation business
         to National Express Group, PLC. The shuttle bus business generated
         approximately $6 million in 1998 revenues. This divestiture allowed AHL
         to retire approximately $4 million in capital lease obligations.

3.       ANNOUNCED ACQUISITION SUBSEQUENT TO JUNE 30, 1999 - On July 27, 1999,

6.       LEGAL MATTERS - AHL has learned that the U.S. Attorney's Office for the
         Eastern District of Pennsylvania is investigating prior recruiting and
         training practices and other matters at the Philadelphia location of
         Argenbright Security, Inc. ("Argenbright Security"), a subsidiary of
         the Company, and that Argenbright Security is a target of this
         investigation. The Company believes that certain employees, who have
         since been terminated, may have violated FAA regulations, as well as
         Company policies and procedures in these

                                       6

         matters. The FAA has reviewed Argenbright Security's other major
         airport locations and has not uncovered any similar issues. The Company
         has been informed that the matters being investigated are limited to
         the operations of the Philadelphia office, and the Company does not
         believe that the matters under review represent a systemic problem.
         Since learning of the issues, the Company has taken the necessary
         actions to ensure compliance with all FAA regulations and Company
         policies and procedures in Philadelphia. Additionally, management has
         reviewed this investigation with the major clients of its Philadelphia
         operations and the Company does not believe that this investigation has
         had any adverse affect on its relationship with these clients.

         The Company is cooperating with the U.S. Attorneys' Office in this
         investigation and believes this investigation may be concluded in the
         next several months. In the third quarter of 1999, the Company plans to
         take a special one-time charge of $500,000 to cover potential
         attorneys' fees and expenses associated with this investigation.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results
of Operations

OPERATING RESULTS - THREE MONTHS ENDED JUNE 30, 1999 AND 1998
Revenues increased $90.7 million, or 92%, to $189.6 million for the second
quarter of 1999 from $98.9 million in the second quarter of 1998. Second quarter
1999 revenues included approximately $71.0 million attributable to acquisitions
owned less than one year. The remaining increase was a result of providing
additional services to existing clients, entering into contracts to provide
services to new clients and rate increases on existing contracts.

Cost of services represents the direct costs attributable to a specific
contract, predominantly wages and related benefits, as well as certain related
expenses such as workers' compensation and other direct labor related expenses.
Cost of services increased $59.1 million, or 81%, to $131.8 million for the
second quarter of 1999 from $72.8 million in the second quarter of 1998. As a
percentage of revenues, cost of services decreased to 69.5% for the second
quarter of 1999 from 73.6% in the second quarter of 1998. This decrease was
primarily due to the effect of the growth in revenues of the Company's higher
margin marketing execution and fulfillment services businesses.

Gross margin increased $31.6 million, or 121%, to $57.7 million for the second
quarter of 1999 from $26.1 million in the second quarter of 1998. As a
percentage of revenues, gross margin improved to 30.5% for the second quarter of
1999 from 26.4% in the second quarter of 1998.

Field operating expenses represent expenses which directly support field
operations, such as each district's management, facility expenses (such as rent,
communication costs and taxes), employee uniforms, equipment leasing,
maintenance, local sales and marketing activities. These expenses increased
$23.2 million, or 153%, to $38.4 million for the second quarter of 1999 from
$15.2 million in the second quarter of 1998. As a percentage of revenues, field
operating expenses increased to 20.2% for the second quarter of 1999 from 15.4%
in the second quarter of 1998. This percentage increase was primarily
attributable to the facility expenses of Gage Marketing Support Services, a
company acquired in July 1998, which operates in the Company's marketing
execution and fulfillment services segment.

Corporate general and administrative expenses, which includes the cost of
services the Company provides to support and manage its field activities,
increased $105,000, or 2.4%, to $4.6 million for the second quarter of 1999 from
$4.5 million in the second quarter of 1998. As a percentage of revenues, these
expenses decreased to 2.4% for the second quarter of 1999 from 4.5% in the
second quarter of 1998. This percentage decrease was primarily due to better
leveraging of corporate personnel and allocation of certain corporate personnel
to field operations for the second quarter of 1999.

Depreciation and amortization increased $2.3 million, or 113%, to $4.3 million
for the second quarter of 1999 from $2.0 million in the second quarter of 1998.
As a percentage of revenues, these expenses increased to 2.3% for the second
quarter of 1999 from 2.0% in the second quarter of 1998. The increase was
primarily due to the depreciation and amortization expense of acquisition
related fixed and intangible assets.

Operating income increased $6.1 million, or 136%, to $10.5 million for the
second quarter of 1999 from $4.4 million in the second quarter of 1998. As a
percentage of revenues, operating income improved to 5.5% for the second quarter
of 1999 from 4.5% in the second quarter of 1998.

                                       8

<PAGE>   11

Interest expense increased $2.0 million to $2.2 million for the second quarter
of 1999 from $177,000 in the second quarter of 1998. Interest expense increased
in 1999 due to the use of the Company's credit facility to fund acquisitions.

Other income, net, increased $318,000 to $335,000 for the second quarter of 1999
from $17,000 for the second quarter of 1998 as a result of the gain on the
Company's sale of its UK bus transportation business which occurred on June 30,
1999.

Income tax provision increased $1.5 million, or 89%, to $3.2 million for the
second quarter of 1999 from $1.7 million in the second quarter of 1998. The
Company provided income taxes at a rate of 37.9% in the second quarter of 1999
and 40.0% in the second quarter of 1998. The decrease in the effective tax rate
in 1999 as compared to 1998 is due to the change in business mix by country as a
result of the acquisitions made after the second quarter of 1998.

Net income increased $2.8 million, or 108%, to $5.3 million, or 2.8% of
revenues, for the second quarter of 1999 from net income of $2.6 million, or
2.6% of revenues, in the second quarter of 1998.

OPERATING RESULTS - SIX MONTHS ENDED JUNE 30, 1999 AND 1998
Revenues increased $176.8 million, or 96%, to $360.2 million for the six months
ended June 30, 1999 from $183.4 million for the six months ended June 30, 1998.
Revenues for the six months ended June 30, 1999 included approximately $137.4
million attributable to acquisitions owned less than one year. The remaining
increase was a result of providing additional services to existing clients,
entering into contracts to provide services to new clients and rate increases on
existing contracts.

Cost of services increased $116.0 million, or 86%, to $251.6 million for the six
months ended June 30, 1999 from $135.6 million for the six months ended June 30,
1998. As a percentage of revenues, cost of services decreased to 69.8% for the
six months ended June 30, 1999 from 73.9% for the six months ended June 30,
1998. This decrease was primarily due to the effect of the growth in revenues of
the Company's higher margin marketing execution and fulfillment services
businesses.

Gross margin increased $60.9 million, or 127%, to $108.6 million for the six
months ended June 30, 1999 from $47.8 million for the six months ended June 30,
1998. As a percentage of revenues, gross margin improved to 30.2% for the six
months ended June 30, 1999 from 26.1% for the six months ended June 30, 1998.

Field operating expenses increased $44.0 million, or 157%, to $72.1 million for
the second quarter of 1999 from $28.1 million for the six months ended June 30,
1998. As a percentage of revenues, field operating expenses increased to 20.0%
for the six months ended June 30, 1999 from 15.3% for the six months ended June
30, 1998. This percentage increase was primarily attributable to the facility
expenses of Gage Marketing Support Services, a company acquired in July 1998,
which operates in the Company's marketing execution and fulfillment services
segment.

Corporate general and administrative expenses increased $933,000, or 10.6%, to
$9.7 million for the six months ended June 30, 1999 from $8.8 million for the
six months ended June 30, 1998. As a percentage of revenues, these expenses
decreased to 2.7% for the six months ended June 30, 1999 from 4.8% for the six

months ended June 30, 1998. This percentage decrease was primarily due to better
leveraging of corporate personnel and allocation of certain corporate personnel
to field operations in the second quarter of 1999.

Depreciation and amortization increased $4.6 million, or 126%, to $8.3 million
for the six months ended June 30, 1999 from $3.7 million for the six months
ended June 30, 1998. As a percentage of revenues, these expenses increased to
2.3% for the six months ended June 30, 1999 from 2.0% for the six months ended

amortization expense of acquisition related fixed and intangible assets.

Operating income increased $11.3 million, or 156%, to $18.5 million for the six
months ended June 30, 1999 from $7.2 million for the six months ended June 30,
1998. As a percentage of revenues, operating income improved to 5.1% for the six
months ended June 30, 1999 from 3.9% for the six months ended June 30, 1998.

Interest expense increased $4.2 million to $4.4 million for the six months ended
June 30, 1999 from $214,000 for the six months ended June 30, 1998. Interest
expense increased in 1999 due to the use of the Company's credit facility to
fund acquisitions.

Income tax provision increased $2.5 million, or 86%, to $5.4 million for the six
months ended June 30, 1999 from $2.9 million for the six months ended June 30,
1998. The Company provided income taxes at a rate of 37.5% in 1999 and 40.0% in
1998. The decrease in the effective tax rate for the six months ended June 30,
1999 as compared to the six months ended June 30, 1998 is due to the change in
business mix by country as a result of the acquisitions made after the second
quarter of 1998.

Net income increased $4.7 million, or 106%, to $9.1 million, or 2.5% of
revenues, for the six months ended June 30, 1999 from net income of $4.4
million, or 2.4% of revenues, for the six months ended June 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES
Cash used in operating activities was $29.5 million for the six months ended
June 30, 1999 compared to $2.5 million for the six months ended June 30, 1998.
This increase was primarily the result of an increase of $9.3 million in net
income before depreciation and amortization offset by $36.3 million of changes
in working capital due to increases in accounts receivable as a result of the
Company's acquisitions, the growth in revenues and the timing of payments of
accounts payable and accrued expenses, primarily relating to the Company's
marketing execution businesses acquired since the end of the second quarter of
1998. Cash used in investing activities for the six months ended June 30, 1999
was $89.8 million compared to $21.6 million for the six months ended June 30,
1998. The use of cash for investing activities was principally a result of the
acquisitions made during the periods. Cash provided by financing activities for
the six months ended June 30, 1999 was $118.8 million compared to $13.9 million
for the six months ended June 30, 1998. In January 1999, the Company completed a
follow-on public offering of its common stock. The Company issued 3,255,570
shares at an offering price of $31 per share. The total proceeds, net of
underwriting discounts and offering expenses, were approximately $96.1 million,
of which the Company used a portion to repay a $10 million subordinated
convertible debenture. The remaining $86.1 million was used to reduce the
outstanding balance under the credit facility.

Capital expenditures were approximately $4.7 million for the six months ended
June 30, 1999 compared to $4.0 million for the six months ended June 30, 1998.
Historically, capital expenditures have been, and future



                                       10
<PAGE>   13

expenditures are anticipated to be, primarily to support expansion of the
Company's operations, including equipment and management information systems.

Effective April 23, 1999, the Company expanded its credit facility to $250
million with a syndicate of banks led by First Union National Bank. The Company
plans to utilize the facility to grow its business through strategic
acquisitions. At June 30, 1999, there was approximately $66 million of
availability remaining under the credit facility.

The Company believes that funds generated from operations, together with
existing cash and borrowings under the credit facility, will be sufficient to
finance its current operations, planned capital expenditures and internal growth
for at least the next several years. If the Company were to make a significant
acquisition or series of acquisitions for cash, it may be necessary for the
Company to obtain additional debt or equity financing.

YEAR 2000 ISSUE

The Company is currently in the process of addressing the Year 2000 issue, which
is the result of computer programs being written using two digits rather than
four to define the applicable year. As a result, computer applications and
software may recognize an input of two zeros (00) as the year 1900. This
incorrect date recognition could cause systems and software malfunctions that
may have a material adverse effect on business operations. This potential
problem could affect not only the Company's internal information systems but
also those of third parties, such as clients and vendors using information
systems that may interact with or affect the Company's operations.



                                       11

COMPANY'S READINESS - To ensure minimal business interruption due to computer
failures, the Company has performed a review of various software applications
and computer infrastructure that are likely to be affected by the Year 2000
issue. Both "IT systems" and "non-IT systems" were reviewed. IT systems refer to
all pre-packaged and internally developed software applications and programs and
related computer hardware. Non-IT systems refer to various equipment and devices
that have "embedded" computer language, examples of which are computer
integrated circuits ("chips") and telephone switches. The review was completed
using the Company's employees and various computer consulting vendors.

The Company's response is being conducted in phases. First, all relevant
computer systems were assessed as to functionality and to determine Year 2000
compliance. Second, for those systems and software found to be non-compliant or
in need of upgrading, corrective steps are being taken. Corrective steps
primarily relate to development and purchasing of system software and hardware.
Finally, all systems will be tested and then implemented at necessary levels.
The Company has substantially completed the corrective and testing phases and is
well into the implementation phase. The Company's objectives are to complete
substantially all remediation and replacement of internal information systems by
October 1999, and to complete final testing and certification for Year 2000
readiness by November 1999.

The Company presently believes that, with planned conversions to new software,
the Year 2000 issue will not pose significant operational problems for its
computer systems.

The Company has identified its significant clients and vendors that it believes,
at this time, to be critical to the Company's business operations, and steps are
underway to ascertain their respective stages of readiness through the use of
questionnaires, interviews, and other available means to determine the progress
that those clients and vendors are making in remediating their own Year 2000
issues. The Company is requiring that significant clients and vendors certify
those products and services to be Year 2000 compliant. However, there can be no
assurance that the information systems provided by or utilized by other
companies which affect the Company's operations will be timely revised in such a
way as to allow them to continue normal business operations or furnish products,
services or data to the Company without disruption.

COST OF COMPLIANCE - The Company is replacing its non-compliant systems.
Preliminary estimates for these new systems are in the range of $2.0 to $3.0
million. To date, the Company has incurred capital expenditures of approximately
$2.0 million. The Company's Year 2000 project costs are not expected to have a
material impact on its results of operation or financial condition.

COMPANY RISK AND CONTINGENCY PLANS - The Company's systems identified as
non-compliant or in need of replacement are being replaced. The Company expects
these replacements to be substantially completed by year-end 1999. If needed
conversions to the Company's information systems are not made on a timely basis
or the Company's significant clients or vendors fail to make such remediations
and conversions on a timely basis, it could have a material adverse effect on
the Company's results of operations or financial condition.

Item 3 - Quantitative and Qualitative Disclosures About Market Risk

FOREIGN CURRENCY RISK - A substantial amount of the Company's revenues are
received, and operating costs are incurred, in foreign currencies (primarily the
British pound and the German deutsche mark), with a significant amount of
operating income being derived from operations in the United Kingdom and
Germany. The denomination of foreign subsidiaries' account balances in their
local currency exposes the Company to



                                       12
<PAGE>   15

certain foreign exchange rate risks. The Company addresses the exposure by
financing most working capital needs in the applicable foreign currencies. The
Company does not engage in hedging transactions to reduce exposure to
fluctuations in foreign currency exchange rates. Historically, the impact of
foreign currency fluctuations on the Company has been insignificant.

INTEREST RATE RISK - The Company maintains a credit facility, an interest rate
swap agreement and other long-term debt which subjects the Company to the risk
of loss associated with movements in market interest rates. The Company's
five-year credit facility had a balance outstanding at June 30, 1999 of $184.5
million, which was at a variable rate of interest. In order to hedge against
increasing interest rates, effective October 6, 1998, the Company entered into a
four-year interest rate swap agreement with a notional amount of approximately
$30.0 million to offset a portion of the floating interest rate risk. On May 14,
1999, this swap agreement was replaced with a three-year interest rate swap
agreement with a notional amount of approximately $50.0 million. The fair value
of the new swap agreement at June 30, 1999 approximates the value when entered
into in May 1999. Thus, if the Company were to unwind the swap agreement, no
material gain or loss would be recognized. A change in the prevailing interest
rates of 10% would result in a change in the total fair value of long-term debt
of approximately $4.9 million. Fair values were determined from discounted cash
flows.

PART II - OTHER INFORMATION AND SIGNATURE

Item 1 - Legal Proceedings

         AHL has learned that the U.S. Attorney's Office for the Eastern
District of Pennsylvania is investigating prior recruiting and training
practices and other matters at the Philadelphia location of Argenbright
Security, Inc. ("Argenbright Security"), a subsidiary of the Company, and that
Argenbright Security is a target of this investigation. The Company believes
that certain employees, who have since been terminated, may have violated FAA
regulations, as well as Company policies and procedures in these matters. The
FAA has reviewed Argenbright Security's other major airport locations and has
not uncovered any similar issues. The Company has been informed that the matters
being investigated are limited to the operations of the Philadelphia office, and
the Company does not believe that the matters under review represent a systemic
problem. Since learning of the issues, the Company has taken the necessary
actions to ensure compliance with all FAA regulations and Company policies and
procedures in Philadelphia. Additionally, management has reviewed this
investigation with the major clients of its Philadelphia operations and the
Company does not believe that this investigation has had any adverse affect on
its relationship with these clients.

         The Company is cooperating with the U.S. Attorneys' Office in this
investigation and believes this investigation may be concluded in the next
several months. In the third quarter of 1999, the Company plans to take a
special one-time charge of $500,000 to cover potential attorneys' fees and
expenses associated with this investigation.
