              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.  BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
of Cannondale Corporation (the Company) have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all the information and footnotes required by
generally accepted accounting principles for complete financial statements. In
the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the three- and nine-month periods ended March 28, 1998 are
not necessarily indicative of the results that may be expected for the year
ending June 27, 1998. For further information, refer to the consolidated
financial statements and footnotes thereto for the year ended June 28, 1997
included in the Company's Annual Report on Form 10-K/A.

         In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings Per Share." Statement 128
replaced the previously reported primary and fully diluted earnings per share
with basic and diluted earnings per share. Unlike primary earnings per share,
basic earnings per share excludes any dilutive effects of options, warrants, and
convertible securities. Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share. All earnings per share
amounts for all periods have been presented, and where necessary, restated to
conform to the Statement 128 requirements.

2.  INVENTORY

The components of inventory are as follows (in thousands):

Item 2.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Net Sales. Net sales decreased from $48.2 million in the third quarter of fiscal
1997 to $45.3 million in the third quarter of fiscal 1998, a decrease of $2.9
million or 6.1%. The decrease in sales for the quarter was primarily caused by a
reduction in inventory by many of the Company's domestic dealers and bad weather
in the United States. For the first nine months, net sales increased 5.7% from
$120.4 million in fiscal 1997 to $127.3 million in fiscal 1998, an increase of
$6.9 million. The increase in sales for the first nine months of fiscal 1998 was
a primarily a result of strong international demand for Cannondale products.

Gross Profit. Gross profit as a percentage of net sales decreased to 38.0% for
the third quarter of fiscal 1998 compared to 40.5% for the third quarter of
fiscal 1997. The gross profit for the third quarter of 1998 was $17.2 million, a
decrease of $2.3 million, or 11.9% below the gross profit of $19.5 million for
the third quarter of fiscal 1997. For the first nine months of fiscal 1998,
gross profit as a percentage of net sales decreased to 36.2% compared to 37.9%
in fiscal 1997. The gross profit for the first nine months of fiscal 1998 was
$46.1 million, an increase of approximately $400,000 over the gross profit of
$45.7 million for the for the first nine months of fiscal 1997. In both periods,
the lower gross-profit rate primarily reflects the effect of a stronger U.S.
dollar on sales by the Company's foreign subsidiaries, as the cost of materials
purchased from the U.S. increased compared to the same period last year. The
impact of the stronger U.S. dollar offset the benefits of a mix that favored
international markets, cost-reduction programs and the Company's continued
integration of proprietary technology through the use of its Cannondale bicycle
frames, CODA components and HeadShok suspension systems.

Operating Expenses. Operating expenses were $11.8 million for the third quarter
of fiscal 1998, an increase of approximately $1.4 million, or 13.9% over the
third quarter fiscal 1997 operating expenses of $10.4 million. For the first
nine months of fiscal 1998, operating expenses were $33.4 million, an increase
of approximately $3.6 million, or 11.9% over the $29.8 million recorded for the
first nine months of fiscal 1997.

For both periods, increased selling, general and administrative expenses, offset
by the effect of a stronger U.S. dollar, were primarily associated with meeting
the Company's current and planned growth objectives. The additional expenses
related to personnel hired for the expanded field-sales force, increased
investment in international marketing, increased depreciation expense associated
with the growth of capital expenditures and expenses associated with upgrading
the Company's shipping system. As a percentage of net sales, selling, general
and administrative expenses remained relatively constant during the first nine
months of fiscal 1998 at 22.9%, compared to 22.6% during the prior-year period.

The increase in research and development expenses reflects the Company's
commitment to innovation and the generation of new products and manufacturing
processes. During the first nine months of fiscal 1998, as a percentage of net 
<PAGE>   9
sales, the Company increased its investment in research and development to 3.4%
compared to 2.2% during the prior-year period.

Other income (expense). Interest expense for the third quarter of fiscal 1998
was $685,000, an increase of approximately $142,000 from the third quarter of
fiscal 1997. Adjusted for capitalized interest costs related to the construction
of the Company's new headquarters facility and the expansion of the
manufacturing facility, interest expense for the first nine months of fiscal
1998 was $1.3 million, an increase of approximately $103,000 from the first nine
months of fiscal 1997. In both periods, the increase in interest expense
reflects the effect of higher average borrowings primarily relating to the
Company's common stock repurchase program and increased capital expenditures,
partially offset by lower interest rates available under the Company's unsecured
multi-currency revolving credit facility.

In both periods, other income primarily represents the receipt of finance
charges payable by dealers.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities was $17.8 million for the first nine
months of fiscal 1998, which was relatively constant compared to the $18.2
million used for the first nine months of fiscal 1997. The net use of cash is
typical for the first nine months of the fiscal year due to seasonal activity,
which includes higher working capital requirements during the busiest shipping
period of the fiscal year and seasonal terms offered to dealers through the
Company's Authorized Retailer Program.

Capital expenditures were $10.6 million for the first nine months of fiscal
1998, compared to $6.2 million in the first nine months of fiscal 1997. The
increase in spending primarily reflects the completion of the Company's new
administrative headquarters and research and development facility and the
expansion of the Company's production facility in fiscal 1998, which was
required to support increases in production volume and to support future growth.
During fiscal 1997, the proceeds from the sale of the Company's former
headquarters facility, $1.7 million, were reinvested in this expansion.

Net cash provided by financing activities for the first six months of fiscal
1998 was $23.6 million, an increase of $2.9 million compared to the $20.7
million for the first nine months of fiscal 1997. Net cash provided by financing
activities in the first nine months of the fiscal year primarily represents
borrowings under the Company's long-term revolving credit facility to meet its
operating and capital requirements. The increase in proceeds from long-term
borrowings in fiscal 1998 primarily reflects the investment in its new
administrative headquarters and research and development facility and the
expansion of the Company's production facility, as well as the effect of the
repurchase of $10.1 million of the Company's common stock. The Company is
authorized to repurchase up to 1,000,000 shares of its common stock at an
aggregate price not to exceed $20 million. In order to accommodate the capital
requirements of the repurchase program, on October 14, 1997, the Company and its
lenders amended the revolving credit facility to allow the Company and its
subsidiaries to borrow up to $70 million. The amendment to the revolving credit
facility includes adjustments to specified levels of tangible net worth and cash
flow levels that the Company must maintain.
<PAGE>   10
The Company expects that cash flow generated by its operations and borrowings
under the revolving credit facilities will be sufficient to meet its planned
operating and capital requirements, and to accommodate the capital requirements
of the Company's share repurchase program for the foreseeable future. 

YEAR 2000 COMPLIANCE

The Company has performed an examination of its hardware and software
applications to determine whether the systems it uses to operate its business
are prepared to accommodate the year 2000. Upon identifying the applications
that require modification to accommodate year 2000 dating, the Company initiated
a program to modify the software using third-party service providers. This
program is currently in process and the Company anticipates that it will be
completed by the end of fiscal year 1999. The Company believes that the cost
associated with the modifications of software will not be material to its
financial results. In concert with the Company's assessment of its internal
systems, it also initiated a program to contact its major third-party suppliers
to determine their status with year 2000 compliance. This program is in progress
and the Company has not completely assessed the status of its third-party
suppliers and the year 2000 problem. Based on its current examination of the
