1. INTERIM CONSOLIDATED FINANCIAL STATEMENTS

In the opinion of management, the unaudited Interim Consolidated Financial
Statements of Greyhound Lines, Inc. and Subsidiaries (the "Company") include all
adjustments, consisting of only normal recurring adjustments, necessary to
present fairly the Company's financial position as of March 31, 2001, the
results of its operations for the three months ended March 31, 2001 and 2000 and
cash flows for the three months ended March 31, 2001 and 2000. Due to the
seasonality of the Company's operations, the results of its operations for the
interim period ended March 31, 2001 may not be indicative of total results for
the full year. 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 the rules and regulations
promulgated by the Securities and Exchange Commission. The unaudited Interim
Consolidated Financial Statements should be read in conjunction with the audited
Consolidated Financial Statements of Greyhound Lines, Inc. and Subsidiaries and
accompanying notes for the year ended December 31, 2000. For the three months
ended March 31, 2001 and 2000, the Company's comprehensive loss was equal to net
loss.

2. REDEEMABLE PREFERRED STOCK

At March 31, 2001 the Company had 102,500 shares of Redeemable Preferred Stock
outstanding which were convertible into cash at $33.33 per share. On March 30,
2001, the Company issued a redemption notice to the holders of the outstanding
shares of Redeemable Preferred Stock whereby any shares which had not been
validly tendered for conversion by April 27, 2001 were redeemed by the Company
at a price per share of $26.74625. During the notice period 98,700 shares,

aggregate redemption value of $0.1 million, were redeemed by the Company on

ITEM 2. MANAGEMENT'S NARRATIVE ANALYSIS OF RESULTS OF OPERATIONS

GENERAL

Greyhound is the only nationwide provider of scheduled intercity bus
transportation services in the United States. The Company's primary business
consists of scheduled passenger service, package express service and food
services at certain terminals, which accounted for 83.8%, 4.3% and 4.4%,
respectively, of the Company's total operating revenues for the three months
ended March 31, 2001. The Company's consolidated operations include a nationwide
network of terminal and maintenance facilities, a fleet of approximately 2,900
buses and approximately 1,800 sales outlets.

The Company's business is seasonal in nature and generally follows the pattern
of the travel industry as a whole, with peaks during the summer months and the
Thanksgiving and Christmas holiday periods. As a result, the Company's cash
flows are also seasonal with a disproportionate amount of the Company's annual
cash flows being generated during the peak travel periods. The day of the week
on which certain holidays occur, the length of certain holiday periods, and the
date on which certain holidays occur within the fiscal quarter, may also affect
the Company's quarterly results of operations.

RESULTS OF OPERATIONS

The following table sets forth the Company's results of operations as a
percentage of total operating revenue for the quarters ended March 31, 2001 and
2000:

THREE MONTHS ENDED MARCH 31, 2001 AND 2000 RESULTS OF OPERATIONS

Operating Revenues. Total operating revenues increased $13.6 million, up 6.3%,
for the three months ended March 31, 2001, compared to the same period in 2000.

Passenger services revenues increased $12.2 million, or 6.8%, for the three
months ended March 31, 2001, compared to the same period in 2000. The increases
in regular route revenues reflect the combined impact of a 4.7% increase in
yield coupled with a 1.7% increase in number of passengers carried. In response
to rising fuel costs, the Company was able to start instituting ticket price
increases during the first quarter of 2000. The yield improvement obtained
during the first quarter of 2001 is the result of the Company being able to
sustain, and in some cases further raise, ticket prices coupled with the
comparative 2000 period including only a partial quarter of ticket price
increases.

Package express revenues declined $0.4 million, or 4.2%, for the three months
ended March 31, 2001, compared to the same period in 2000 due to reduced
standard product deliveries (the traditional, low-value, terminal to terminal
market segment) offset somewhat by gains in same day and priority product
deliveries. The declines in the standard product are a result of continued
competition, as well as expanded and improved product offerings (such as United
Parcel Service's guaranteed service `brown label' product), from larger package
delivery companies.

Food services revenues increased $0.5 million, or 4.9%, for the three months
ended March 31, 2001, compared to the same period in 2000. Food services
revenues increased over the prior year due primarily to the increase in
passenger traffic, the opening of two additional locations and price increases
on certain retail items and beverages.

Other operating revenues, consisting primarily of revenue from charter and other
in-terminal sales and services, increased $1.4 million, or 8.7%, for the three
months ended March 31, 2001, compared to the same period in 2000. The increase
is primarily attributable to the Company's expansion into "meet and greet"
services provided to cruise lines.

Operating Expenses. Total operating expenses increased $16.2 million, or 7.2%,
for the three months ended March 31, 2001, compared to the same period in 2000.
The increase is attributable to a 2.7% increase in bus miles operated, loss on
asset sales, increased fuel cost, wage increases, driver hiring costs, increased
marketing spending, increased ticket and express commissions due to higher
sales, and health and welfare and management fee increases.

Maintenance costs increased $2.3 million, or 10.4%, for the three months ended
March 31, 2001, compared to the same period in 2000. On a per-mile basis,
maintenance cost increased by 7.6% due to fewer buses under warranty,

increased material and labor related to body repairs ($0.7 million) and brake
jobs ($0.6 million) and higher utility costs ($0.3 million). During 1997 the
Company started introducing 45 foot buses into the fleet and has experienced a
38% reduction in miles between brake jobs and a greater frequency of drum
replacement compared to the 40 foot buses the Company is using.

Transportation expenses which consist primarily of fuel costs and driver
salaries, increased $4.3 million, or 7.3%, for the three months ended March 31,
2001, compared to the same period in 2000, due primarily to increased bus miles,
fuel costs, and higher driver wages. Transportation expenses increased on a
per-mile basis by 4.5% due largely to a 6.0% ($0.7 million) increase in fuel
prices for the first quarter of 2001 compared to the prior year, increased
drivers hired resulting in increased hiring costs ($1.3 million) and the impact
of driver wage increases.

Agents' commissions and station costs increased $1.9 million, or 4.5%, for the
three months ended March 31, 2001, compared to the same period in 2000. The
increase is primarily due to commissions from increased ticket sales, terminal
salaries associated with staffing for the increase in passengers and terminal
salary raises. As a percentage of revenue, agent's commissions and station costs
declined to 19.7%.

Marketing, advertising and traffic expenses increased $1.2 million, or 16.3% for
the three months ended March 31, 2001, compared to the same period in 2000, due
to increased spending to support the increase in revenues, as well as the timing
of media advertising.

Insurance and safety costs increased $0.6 million, or 5.2% for the three months
ended March 31, 2001, compared to the same period in 2000 due to the increased
revenue. As a percentage of sales, insurance and safety costs were virtually
flat compared to prior year.

General and administrative expenses increased $2.9 million, or 9.9%, for the
three months ended March 31, 2001, compared to the same period in 2000 due to
higher health and welfare costs ($1.3 million) as a result of increased cost per
participant and management fees ($1.3 million) charged by the Company's parent,
Laidlaw Inc.

Depreciation and amortization increased by $0.8 million, or 7.7%, for the three
months ended March 31, 2001, compared to the same period in 2000 primarily due
to increased capital expenditures in prior periods.

Operating taxes and licenses expense increased $0.4 million, or 2.6%, for the
three months ended March 31, 2001, compared to the same period in 2000 due to
increased payroll taxes resulting from increased salaries and head-counts
related to higher business volume (including increased miles operated), and
increased fuel taxes due to increased miles.

Operating rents changed only slightly for the three months ended March 31, 2001,
compared to the same period in 2000 as the Company has not had a significant
change in the number of leased properties or buses.

Food services cost of goods sold increased $0.7 million, or 10.8%, for the three
months ended March 31, 2001, compared to the same period in 2000, primarily due
to the increase in food services revenues as well as food and labor cost
increases.

Other operating expenses increased $1.1 million for the three months ended March
31, 2001, compared to the same period in 2000 principally due to losses on
disposal of property, plant and equipment in the first quarter of 2001.

Interest expense increased $2.2 million, or 41.9%, for the three months ended
March 31, 2001, compared to the same period in 2000 due primarily to an increase
in average debt outstanding.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal liquidity requirements are to provide working capital,
to finance capital expenditures, including bus acquisitions and to meet debt
service requirements, including the payment of interest on the 11 1/2% Senior
Notes. The Company's principal sources of liquidity are expected to be cash flow
from operations and borrowings under the Revolving Credit Facility. The Company
believes that its cash flow from operations, together with borrowings under the
Revolving Credit Facility, will fund its working capital and near-term capital
expenditure needs. As of March 31, 2001, the Company had outstanding borrowings
under the Revolving Credit Facility of $68.6 million and availability of $56.4
million.

Net cash used in operating activities for the three months ended March 31, 2001
was $2.3 million, an increase of $1.9 million from the $0.3 million used during
the same period of 2000. The principal reason for the increase is the higher net
loss resulting from increased expenses during the first quarter of 2001. Net
cash used for investing activities for the first quarter of 2001 was $7.7
million compared to the $6.2 million in net proceeds from investing during the
first quarter of 2000. The $13.8 million change is principally due to
sale-leaseback proceeds in the first quarter of 2000. Net cash provided by
financing activities in the first quarter of 2001 was $9.0 million versus $5.4
million used for financing activities during the same period in 2000. The $14.5
million difference is principally due to the redemption of $11.1 million of
Redeemable Preferred Stock in the first quarter of 2000.
