</TABLE>

3.  EARNINGS PER SHARE AMOUNTS

         Earnings per share of common stock are computed using the weighted
average number of shares of common stock and common stock equivalents
outstanding for each period. The weighted average number of shares of common
stock and common stock equivalents used in the computation of earnings per share
was 8,940,564 and 9,052,445 for the three-month periods ended September 27, 1997
and September 28, 1996, respectively. Common stock equivalents include options
to purchase common stock.

         In February 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings per Share," which is required to be adopted on
December 31, 1997. At that time, the Company will be required to change the
method currently used to compute earnings per share and to restate all prior
periods. Under the new requirements for calculating basic (primary) earnings per
share, the dilutive effect of stock options will be excluded. The impact is
expected to result in an increase in primary earnings per share of $.01 per
share for the three-month periods ended September 27, 1997 and September 28,
1996. The impact of Statement 128 on the calculation of fully diluted earnings
per share is not expected to be material.               

4.  SUBSEQUENT EVENT

         In order to accommodate the capital requirements of the Company's
program to repurchase up to 1,000,000 shares of its common stock, in September
1997, the Company and its lender agreed to amend its revolving credit facility
to allow the Company and its subsidiaries to borrow up to $70,000,000. 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.

Item 2.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Net Sales. Net sales increased from $30.9 million in the first quarter of fiscal
1997 to $34.3 million in the first quarter of fiscal 1998, an increase of $3.4
million or 11.1%. Compared to the same period last year, net sales, adjusted for
the effect of a stronger U.S. dollar for the three-month period ended September
27, 1997, increased 21%. 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 was $11.4 million in the first quarter of fiscal
1998, an increase of $1.2 million, or 11.0%, over the gross profit in the first
quarter of fiscal 1997 of $10.2 million. The increase in gross profit was a
result of the continued worldwide demand for Cannondale products. Gross profit
as a percentage of net sales in the first quarter of fiscal 1998 was static at
33.1% for the first quarter of fiscal 1998 compared to the first quarter of
fiscal 1997.  Gross profit benefited from a sales 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.  The benefit of these
factors was offset by the effect of a stronger U.S. dollar on sales by the
Company's foreign subsidiaries.

Operating Expenses. Operating expenses were $10.2 million for the first quarter
of fiscal 1998, an increase of approximately $1.1 million, or 12.4%, over the
first quarter of fiscal 1997 of $9.1 million.

Increased selling, general and administrative expenses, offset by a stronger
U.S. dollar, were directly associated with increased sales, additional personnel
primarily relating to the expanded field-sales force and costs incurred to
support the Saeco professional road cycling team. As a percentage of sales,
selling, general and administrative expenses remained at approximately 27% for
the first three months of fiscal 1998 compared to the first three months of
fiscal 1997.

The increase in research and development expenses reflects the Company's
commitment to improvement of its current products and the generation of new
products and manufacturing processes. As a percentage of sales, the Company
increased its investment in research and development expense to 3.3% for the
first three months of fiscal 1998 compared to 2.5% for the first three months of
fiscal 1997.

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 first quarter of fiscal 1998
was $250,000, a decrease of approximately $99,000 from the first quarter of
fiscal 1997. In the first quarter of fiscal 1998, higher average borrowings were
more than offset by lower interest rates available under the Company's unsecured
multi-currency revolving credit facility. The increase in other income in the
first quarter of fiscal 1998 primarily represents the receipt of finance charges
payable by dealers.
<PAGE>   9
LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $450,000 for the first three
months of fiscal 1998, a decrease of $2.1 million compared to the $2.5 million
provided for the first three months of fiscal 1997. The decrease in cash
provided by operating activities is primarily attributable to relatively larger
increases in inventory and prepaid expenses during the first quarter of fiscal
1998 compared to the first quarter of fiscal 1997, offset by a net increase in
cash provided by trade receivables. Due to the seasonality of the business,
higher inventory levels are typical for the first quarter of the fiscal year in
anticipation of second and third quarter shipments.

Capital expenditures were $3.4 million for the first three months of fiscal
1998, compared to $1.6 million in the first three months of fiscal 1997. The
increase in spending primarily reflects the Company's investment in the
Company's new administrative headquarters and research and development facility
and the expansion of the Company's production facility, which is required to
support the increases in production volume and to support future growth.

Net cash provided by financing activities for the first three months of fiscal
1998 was $1.9 million, an increase of approximately $1.4 million compared to the
$489,000 for the first three months of fiscal 1997. The net cash provided by
financing activities in fiscal 1998 primarily reflects the net proceeds from
borrowings under the Company's long-term revolving credit facility to meet its
operating and capital requirements, and to finance the Company's program to
repurchase shares of its 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, in September 1997, the Company and its lender agreed to amend the
Company's revolving credit facility to allow the Company and its subsidiaries to
borrow up to $70 million. 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.

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.
