                               SEPTEMBER 30, 2000
                                   (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 September 30, 2000 and the results of its operations for
         the three and nine months ended September 30, 2000 and 1999 and its
         cash flows for the nine months ended September 30, 2000 and 1999. All
         such adjustments are of a normal recurring nature. The results of
         operations for the three and nine months ended September 30, 2000 are
         not necessarily indicative of the results to be expected for the year
         ended December 31, 2000. For further information, refer to the
         consolidated financial statements and footnotes thereto for the year
         ended December 31, 1999 included in the Company's annual report on Form
         10-K for such period.

2.       ACQUISITIONS - On July 5, 2000, AHL acquired two additional outsourced
         staffing companies in Germany for $14.4 million in cash, building the
         Company's position as one of Germany's leading staffing companies.
         Gesellschaft Fuer Zeitarbeit mbH - Heilbron and Gesellschaft Fuer
         Zeitarbeit mbH - Eisenach ("GFZ"), headquartered in Southern Germany,
         provides skilled and semi-skilled workers to auto parts manufacturers.
         Its 1999 revenues were approximately $11 million. HPD Harzer
         Personaldienst GmbH and APS Personalservice GmbH ("HPD") is
         headquartered in Wernigerode, Eastern Germany, and had 1999 revenues of
         approximately $10 million.

         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.

3.       EVENTS SUBSEQUENT TO QUARTER END

         Divestiture of U.S. Industrial Staffing Businesses
         On October 13, 2000, the Company sold its U.S. Industrial Staffing
         businesses to an investor group led by the President of AHL's Baltimore
         staffing operation. This business, which had revenues for the 12 months
         ending September 30, 2000 of approximately $53.5 million, was sold for
         $22.5 million which includes notes receivable from the purchaser of
         $9.5 million. In addition, the Company retained the accounts receivable
         of the business which totaled approximately $7.4 million at September
         30, 2000. Cash proceeds will be used to retire debt. The Company will
         record a non-operating loss on this sale of approximately $2.9 million,
         which primarily relates to transition concessions granted to the
         purchaser upon closing.

         PIMMS Arbitration Award
         In April 1999, AHL acquired PIMMS, an outsourced merchandising company.
         The Company filed an arbitration claim under the terms of the Purchase
         Agreement in August 1999 based on breach of


                                       6

         representations and warranties. Upon completion of the arbitration
         proceeding on October 2, 2000, the Company was awarded $5.2 million
         plus attorneys' fees, consultant fees, arbitration fees and other
         costs. The Company will record this award, net of escrow adjustments,
         in the fourth quarter of 2000 as a reduction of the goodwill originally
         recorded with the PIMMS acquisition.

6.       CONTINGENCIES - The Company recognizes revenue for Aviation Services,
         Facility Services, and Operational Support Services as services are
         performed. The Company recognizes revenue for Marketing Support
         Services as projects are completed, services are rendered and/or as
         products are shipped. In the ordinary course of business, Marketing
         Support Services projects generate various routine disputes and claims
         between the Company and its customers. At September 30, 2000, such
         claims and disputes represented less than 6% of the Company's accounts
         receivable balance. The Company has entered into non-binding
         arbitration with a customer involving disputed amounts due the Company
         for services performed under a contract. Additionally, the Company has
         had continued discussions regarding disputed accounts receivable with
         another customer for services performed under another contract. The
         gross amount of receivables due from these two customers approximates
         $10 million. Management is of the opinion that these claims and
         disputes will be resolved within the existing reserves established for
         uncollectable receivables.

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

OPERATING RESULTS - THREE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999 - Revenues
increased $23.0 million, or 11%, to $240.4 million for the third quarter of 2000
from $217.4 million for the third quarter of 1999. Third quarter 2000 revenues
were positively impacted by the effect of acquisitions and internal growth.
Third quarter of 1999 revenues would have been approximately $17.5 million
higher with the impact of acquisitions subsequent to July 1, 1999 treated as
though they were acquired on July 1, 1999. Third quarter of 2000 revenues were
negatively impacted as compared to the third quarter of 1999 by the decline in
foreign currencies versus the U.S. dollar, primarily the British pound and the
German deutsche mark. Third quarter of 2000 revenues were negatively impacted by
approximately $11.2 million due to the effect of foreign currency exchange
rates. The remaining increase, after the impact of acquisitions and foreign
currency exchange rates, 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 $16.8 million, or 11%, to $167.2 million for the
third quarter of 2000 from $150.4 million for the third quarter of 1999. As a
percentage of revenues, cost of services increased to 69.6% for the third
quarter of 2000 from 69.2% for the third quarter of 1999. This slight increase
was primarily due to the effect of the growth of the Company's Operational
Support Services business in 2000.

Gross margin increased $6.2 million, or 9%, to $73.2 million for the third
quarter of 2000 from $67.0 million for the third quarter of 1999. As a
percentage of revenues, gross margin declined slightly to 30.4% for the third
quarter of 2000 from 30.8% for the third quarter of 1999.

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 and local sales and marketing activities. These expenses increased
$6.1 million, or 15%, to $46.4 million for the third quarter of 2000 from $40.3
million for the third quarter of 1999. As a percentage of revenues, field
operating expenses increased to 19.3% for the third quarter of 2000 as compared
to 18.5% for the third quarter of 1999, due to the growth of the Company's
Marketing Services businesses which have higher field operating costs, the
investment by the Company in a consolidated back office operation in Munich,
Germany for the Company's German Operational Support Services business in 2000
and the placement of certain management and back office employees of the U.K.
operations in field operating costs in 2000 versus at corporate in 1999.

Corporate, general and administrative expenses, which includes the cost of
services the Company provides to support and manage its field activities,
decreased $876,000, or 15%, to $4.8 million for the third quarter of 2000 from
$5.7 million in the third quarter of 1999. As a percentage of revenues, these
expenses decreased to 2.0% for the third quarter of 2000 from 2.6% for the third
quarter of 1999, due to better leveraging of corporate personnel and accounting
for certain management and back office employees of the U.K. operations in field
operating expenses in 2000 rather than in corporate, general and administrative
expenses as in previous years.

Depreciation and amortization increased $719,000, or 14%, to $5.7 million for
the third quarter of 2000 from $5.0 million for the third quarter of 1999. As a
percentage of revenues, these expenses increased to 2.4% for the third quarter
of 2000 from 2.3% for the third quarter of 1999. The increase was primarily due
to the depreciation and amortization expense of acquisition related fixed and
intangible assets.


                                       8


<PAGE>   10

Operating income increased $235,000, or 2%, to $16.3 million for the third
quarter of 2000 from $16.0 million for the third quarter of 1999. As a
percentage of revenues, operating income was 6.8% for the third quarter of 2000
as compared to 7.4% for the third quarter of 1999.

Interest expense increased $1.5 million, or 43%, to $4.9 million for the third
quarter of 2000 from $3.4 for the third quarter of 1999. This increase was due
to the increase in the outstanding debt balance in 2000 as compared to 1999 due
to the use of the Company's credit facility to fund acquisitions, the repurchase
of shares of AHL's common stock in 2000, and the significant rise in interest
rates in 2000 compared to 1999.

Income tax provision decreased $216,000, or 4%, to $4.8 million for the third
quarter of 2000 from $5.0 million in the third quarter of 1999. The Company
provided income taxes at a rate of 42.0% for the third quarter of 2000 and 39.4%
for the third quarter of 1999. The increase in the effective tax rate in 2000 as
compared to 1999 is due to the change in business mix by country as a result of
acquisitions.

Net income decreased $1.1 million, or 14%, to $6.6 million, or 2.7% of revenues,
for the third quarter of 2000 from net income of $7.7 million, or 3.5% of
revenues, for the third quarter of 1999.

OPERATING RESULTS - NINE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999 - Revenues
increased $105.8 million, or 18%, to $683.4 million for the nine months ended
September 30, 2000 from $577.6 million for the nine months ended September 30,
1999. Revenues for the nine months ended September 30, 2000 were positively
impacted by the effect of acquisitions and internal growth. Revenues for the
nine months ended September 30, 1999 would have been approximately $40.4 million
greater with the impact of acquisitions subsequent to January 1, 1999 treated as
though they were acquired on January 1, 1999. Revenues for the nine months ended
September 30, 1999 included approximately $5.0 million attributable to the U.K.
transportation business sold on June 30, 1999. Revenues for the nine months
ended September 30, 2000 were negatively impacted as compared to the revenues
for the nine months ended September 30, 1999 by the decline in foreign
currencies versus the U.S. dollar, primarily the British pound and the German
deutsche mark. Revenues for the nine months ended September 30, 2000 were
negatively impacted by approximately $22.1 million due to the effect of foreign
currency exchange rates. The remaining increase, after the impact of
acquisitions and foreign currency rates, 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 $72.5 million, or 18%, to $474.4 million for the nine
months ended September 30, 2000 from $401.9 million for the nine months ended
September 30, 1999. As a percentage of revenues, cost of services decreased
slightly to 69.4% for the nine months ended September 30, 2000 from 69.6% for
the nine months ended September 30, 1999 due to a changing mix of revenues by
operating segments as a result of acquisitions.

Gross margin increased $33.4 million, or 19%, to $209.0 million for the nine
months ended September 30, 2000 from $175.6 million for the nine months ended
September 30, 1999. As a percentage of revenues, gross margin improved to 30.6%
for the nine months ended September 30, 2000 from 30.4% for the nine months
ended September 30, 1999.

Field operating expenses increased $29.8 million, or 27%, to $142.2 million for
the nine months ended September 30, 2000 from $112.4 million for the nine months
ended September 30, 1999. As a percentage of revenues, field operating expenses
increased to 20.8% for the nine months ended September 30, 2000 as

compared to 19.5% for the nine months ended September 30, 1999, due to a growth
of the Company's Marketing Services businesses which have higher field operating
expenses, the investment by the Company in a consolidated back office operation
in Munich, Germany for the Company's German Operational Support Services
business in 2000 and the placement of certain management and back office
employees of the U.K. operations in field operating costs in 2000 versus at
corporate in 1999.

Corporate, general and administrative expenses decreased $1.0 million, or 6%, to
$14.4 million for the nine months ended September 30, 2000 from $15.4 million in
the nine months ended September 30, 1999. As a percentage of revenues, these
expenses decreased to 2.1% for the nine months ended September 30, 2000 as
compared to 2.7% for the nine months ended September 30, 1999, due to better
leveraging of corporate personnel and the placement of certain management and
back office employees of the U.K. operations in field operating costs in 2000
versus corporate in 1999.

Special charge - Philadelphia settlement of $2.7 million in the first quarter
of 2000 represents legal fees, fines and other costs for the settlement of the
Philadelphia legal matter discussed in Note 4 to the Condensed Consolidated
Financial Statements contained in the Company's report on Form 10-Q for the
quarter ended March 31, 2000.

Depreciation and amortization increased $3.4 million, or 25%, to $16.7 million
for the nine months ended September 30, 2000 from $13.3 million for the nine
months ended September 30, 1999. As a percentage of revenues, these expenses
increased to 2.4% for the nine months ended September 30, 2000 from 2.3% for the
nine months ended September 30, 1999. The increase was primarily due to the
depreciation and amortization expense of acquisition related fixed and
intangible assets.

Operating income decreased $1.4 million, or 4%, to $33.1 million for the nine
months ended September 30, 2000 from $34.5 million for the nine months ended
September 30, 1999. As a percentage of revenues, operating income was 4.8% for
the nine months ended September 30, 2000 as compared to 6.0% for the nine months
ended September 30, 1999.

Interest expense increased $5.8 million, or 75%, to $13.6 million for the nine
months ended September 30, 2000 from $7.8 for the nine months ended September
30, 1999. This increase was due to the increase in the outstanding debt balance
for the nine months ended September 30, 2000 versus the nine months ended
September 30, 1999 due to the use of the Company's credit facility to fund
acquisitions, the repurchase of shares of AHL's common stock in 2000, and the
significant rise in interest rates in 2000 compared to 1999.

Other income, net, decreased $419,000 to $8,000 for the nine months ended
September 30, 2000 from $427,000 for the nine months ended September 30, 1999 as
a result of the gain on the Company's sales of its U.K. bus transportation
business which occurred on June 30, 1999.

Income tax provision decreased $2.2 million, or 22%, to $8.2 million for the
nine months ended September 30, 2000 from $10.4 million in the nine months ended
September 30, 1999. The Company provided income taxes at a rate of 42.0% for the
nine months ended September 30, 2000 and 38.4% for the nine months ended
September 30, 1999. The increase in the effective tax rate in 2000 as compared
to 1999 is due to the change in business mix by country as a result of
acquisitions.

Net income decreased $5.5 million, or 33%, to $11.3 million, or 1.7% of
revenues, for the nine months ended September 30, 2000 from net income of $16.8
million, or 2.9% of revenues, for the nine months ended September 30, 1999.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities was $13.1 million for the nine months
ended September 30, 2000 compared to cash used in operating activities of $36.5
million for the nine months ended September 30, 1999. This increase in cash
provided by operating activities was primarily the result of a change of $51.3
million in working capital due to decreases in days outstanding for accounts
receivable and the timing of payments of accounts payable and accrued expenses,
offset by a $2.1 million decrease in net income before depreciation and
amortization. Cash used in investing activities for the nine months ended
September 30, 2000 was $30.6 million compared to $104.8 million for the nine
months ended September 30, 1999. The use of cash for investing activities was
principally a result of acquisition consideration paid and additions to
property and equipment made during those periods. Cash provided by financing
activities for the nine months ended September 30, 2000 was $19.0 million
compared to $143.1 million for the nine months ended September 30, 1999. The
Company repurchased 1,898,100 shares of its common stock in the nine months
ended September 30, 2000 for $17.5 million. During the first quarter of 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 $15.0 million for the nine months ended
September 30, 2000 compared to $9.5 million for the nine months ended September
30, 1999. Historically, capital expenditures have been, and future expenditures
are anticipated to be, primarily to support expansion of the Company's
operations, including equipment and management information systems.

The credit facility allows the Company to repurchase up to $20.0 million of its
common stock. The Company, during 2000, repurchased 1,898,100 shares at an
average price of $9.22 per share through September 30, 2000. For the period
October 1, 2000 through November 8, 2000, the Company repurchased an additional
22,500 shares at an average price of $7.50 per share.

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 the next twelve months. 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.

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, which is tied to the Euro), 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 certain foreign exchange
rate risks. The Company addresses the exposure by financing most working capital
needs in the applicable foreign currencies. The Company has not engaged in
hedging transactions to reduce exposure to fluctuations in foreign currency
exchange rates.

INTEREST RATE RISK - The Company maintains a credit facility, two interest rate
swap agreements 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 September 30, 2000 of
$244.1 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 in the 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 $45.0
million. On January 31, 2000, the Company entered into an additional interest
rate swap agreement in the notional amount of approximately $15.0 million which
terminates on May 1, 2003. The fair value of the $60.0 million in swap
agreements at September 30, 2000 approximates $60.3 million. 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 $5.0 million. Fair values were
determined from discounted cash flows.
