              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 six-month periods ended December 27, 1997
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.

The following table sets forth the options to purchase shares of common stock at
the respective ranges of exercise prices that were not included in the
computation of diluted earnings per share because the options' exercise prices
were greater than the average market price of the common shares, and therefore,
the effect would be antidilutive:

</TABLE>

4.  LONG-TERM DEBT

         The Company and its lender amended its revolving credit facility to
allow the Company and its subsidiaries to borrow up to $70,000,000 to
accommodate the capital requirements of the Company's program to repurchase up
to 1,000,000 shares of its common stock at an aggregate price not to exceed
$20,000,000. The amendment to the revolving credit facility, dated October 14,
1997, includes adjustments to specified levels of tangible net worth and cash
flow levels that the Company must maintain.


5.  STOCKHOLDERS' EQUITY

         On December 19, 1997, the Company adopted a Stockholders' Rights plan
in which rights to purchase shares of Company common stock were distributed as
dividends, one right per share, to record owners of common stock as of the
close of business on December 22, 1997. Upon becoming exercisable, each right
entitles holders to purchase a certain amount of common stock. The rights are
not exercisable, however, until a person or group acquires more than 20% of
common stock or announces a tender offer which would result in the ownership of
more than 20% of the common stock.

         At the Company's annual meeting held November 12, 1997, the
stockholders of the Company approved an increase in the number of authorized
shares of common stock, par value $.01 per share, from 18,000,000 to 40,000,000.

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

RESULTS OF OPERATIONS

Net Sales. Net sales increased from $41.3 million in the second quarter of
fiscal 1997 to $47.7 million in the second quarter of fiscal 1998, an increase
of $6.4 million or 15.5%. For the first six months, net sales increased 13.6%
from $72.2 million in fiscal 1997 to $82.0 million in fiscal 1998, an increase
of $9.8 million. The increase in sales was a result of the continued worldwide
demand for Cannondale products and a sales mix that favored international
markets.

Gross Profit. Gross profit as a percentage of net sales decreased to 36.8% for
the second quarter of fiscal 1998 compared to 38.5% for the second quarter of
fiscal 1997. The gross profit for the second quarter of 1998 was $17.6 million,
an increase of $1.7 million, or 10.5%, over the gross profit of $15.9 million
for the second quarter of fiscal 1997. For the first six months of fiscal 1998,
gross profit as a percentage of net sales decreased to 35.3% compared to 36.2%
in fiscal 1997. The gross profit for the first six months of fiscal 1998 was
$28.9 million, an increase of $2.8 million, or 10.7%, over the gross profit of
$26.1 million for the for the first six 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 $11.3 million for the second quarter
of fiscal 1998, an increase of approximately $900,000, or 9.4%, over the second
quarter of fiscal 1997 of $10.4 million. For the first six months of fiscal
1998, operating expenses were $21.6 million, an increase of approximately $2.1
million, or 10.8%, over the first six months of fiscal 1997 of $19.5 million.

For both periods, increased selling, general and administrative expenses, offset
by the effect of a stronger U.S. dollar, were directly associated with increased
sales, additional personnel primarily related to the expanded field-sales force,
and increased investment in international marketing to support the Company's
current and planned growth. As a percentage of net sales, selling, general and
administrative expenses improved to 20.4% compared to 22.9% during the
prior-year quarter.

The increase in research and development expenses reflects the Company's
commitment to the improvement of its current products and the generation of new
products and manufacturing processes. During the second quarter of fiscal 1998,
as a percentage of net sales, the Company increased its investment in research
and development to 3.4% compared to 2.2% during the prior year quarter.

Other income (expense). 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 second quarter of fiscal 1998
was $399,000, an increase of approximately $60,000 from the second quarter of
fiscal 1997. For the first six months of fiscal 1998, interest
<PAGE>   9
expense, adjusted for capitalized interest costs was $649,000, a decrease of
approximately $39,000 from the first six months of fiscal 1997. In both periods,
higher average borrowings were offset by lower interest rates available under
the Company's unsecured multi-currency revolving credit facility.

The increase in other income in the second quarter, and for the first six months
of fiscal 1998 compared to fiscal 1997 primarily represents the receipt of
finance charges payable by dealers.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities was $9.7 million for the first six months
of fiscal 1998, a decrease of $1.5 million compared to the $11.2 million used
for the first six months of fiscal 1997. The net use of cash is typical for the
first six months of the fiscal year due to seasonal activity, which includes
higher inventory levels in anticipation of third quarter shipments and seasonal
terms offered to dealers through the Company's Authorized Retailer Program. The
reduction in the use of cash from operating activities in fiscal 1998 compared
to the prior year was primarily attributed to a higher rate of cash collections
from dealers and increased net income.

Capital expenditures were $7.6 million for the first six months of fiscal 1998,
compared to $3.5 million in the first six months of fiscal 1997. The increase in
spending primarily reflects the Company's investment in its new administrative
headquarters and research and development facility and the expansion of the
Company's production facility, 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 $13.1 million, an increase of $2.7 million compared to the $10.4
million for the first six months of fiscal 1997. Net cash provided by financing
activities in the first six 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 borrowings
under the long-term debt agreement in fiscal 1998 primarily reflects the effect
of the repurchase of $4.8 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
lender amended its 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.

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.
