        At September 30, 1997 and December 31, 1996, accounts payable included
approximately $56,000 and $2,356,000, respectively, for the acquisition of fixed
assets.


4. THOMAS KEMPER SODA COMPANY ACQUISITION:

        On March 7, 1997, the Company acquired substantially all of the
operating assets and assumed certain liabilities of Thomas Kemper Soda Company
for approximately $1.7 million including certain transaction costs. The purchase
price was paid with approximately $576,000 in cash and the assumption of
approximately $1,124,000 of liabilities. In connection with the acquisition,
goodwill of approximately $803,000 has been recorded in other assets and is
being amortized over 10 years. During 1996, Thomas Kemper Soda Company had
annual sales of approximately $3.6 million.

5. COMMITMENTS AND CONTINGENCIES:

        The Company is involved from time to time in claims, proceedings and
litigation arising in the ordinary course of business. The Company does not
believe that any such claim, proceeding or litigation, either alone or in the
aggregate, will have a material adverse effect on the Company's financial
position or results of operations.

6. SUBSEQUENT EVENT:

        On October 29, 1997, management announced a restructuring of marketing
and brewery operations. The restructuring will include a refocus of marketing
resources on Western and Southwestern markets and the closure of the Kalama,
Washington plant. Although this marketing decision could result in a reduction
in sales volume in other markets, the Company expects to gain increased
operating efficiencies as it redistributes Kalama production between the Seattle
and Berkeley breweries. The closure of the Kalama plant will reduce total
brewing capacity to 172,000 barrels.

        The Company expects to take a one-time charge against earnings of
approximately $1.6 million in the fourth quarter ending December 31, 1997 for
write-offs related to the disposal of fixed assets, severance payments and other
plant closure costs. The restructuring of marketing and brewery operations is
expected to reduce current fixed costs and SG&A expenses by approximately $1.0
million per year commencing in 1998.

QUARTER ENDED SEPTEMBER 30, 1997 COMPARED TO QUARTER ENDED SEPTEMBER 30, 1996

        Gross Sales. Gross sales increased by 18.1% to $8.5 million for the
third quarter ended September 30, 1997 from $7.2 million in the same quarter of
the prior year. The increase resulted primarily from sales of Thomas Kemper Soda
of $1.0 million, acquired in March of 1997 and an 54.5% increase in retail sales
from $1.1 million to $1.7 million, due to the opening of the Berkeley Alehouse
in February of 1997. Gross wholesale craft beer sales decreased 5.0% to $5.7
million for the third quarter of 1997 from $6.0 million in the same quarter of
the prior year due to a 3.9% volume decrease and an increase in the proportion
of draft beer sales. The product mix shifted to a higher percentage of draft
sales (35.1% for the quarter ended September 30, 1997 versus 31.3% for the same
quarter of the prior year) which resulted in lower sales dollars per barrel
sold.

        Excise Taxes. Excise taxes decreased to 7.3% of net sales for the third
quarter ended September 30, 1997 from 7.7% of net sales in the same quarter of
the prior year. The decrease in excise taxes as a percentage of net sales was
due primarily to an underestimate of the small brewers federal excise tax credit
during the third quarter of the prior year.

        Gross Margin. Gross margin decreased to $1.9 million for the third
quarter ended September 30, 1997 from $2.6 million in the same quarter of the
prior year. Gross margin as a percentage of net sales declined to 24.6% for the
third quarter ended September 30, 1997 from 39.5% for the same quarter of the
prior year. This decrease as a percentage of net sales was due to higher fixed
and semi-fixed costs, including increases in depreciation, increased package
design costs, increased freight costs incurred servicing more distant markets
and the lower gross margin associated with the increase in sales from retail
operations (primarily sales of beer, food and branded merchandise at the
Company's Alehouses). Changes in the cost of raw materials and packaging did
not, in the aggregate, have a significant impact on gross margin during either
period.

        Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased to $2.1 million, or 26.4% of net sales, for
the third quarter ended September 30, 1997 from $1.6 million, or 24.8% of net
sales, for the same quarter of the prior year. This increase was due primarily
to the planned increase in selling and promotional expenditures attributable to
the geographic expansion of beer sales territories. The Company's sales and
marketing staff increased from 28 to 41 employees and it distributed its craft
beers in 36 states as of September 30, 1997, up from 27 states at September 30,
1996. Management believes that sales and promotional expenses in its core
markets are necessary investments for the future of the Company.

        Other (Expense) Income. The Company incurred other expense of $121,226
for the third quarter ended September 30, 1997 as compared to other income of
$310,632 reported for the third quarter of the prior year. The decrease in other
income was due primarily to a decrease in interest income earned, net of bond
premium amortization, from investing the net proceeds of the initial public
stock offering, which proceeds were primarily used to finance construction of
the Company's Berkeley Brewery and Alehouse and upgrades to the Seattle Brewery.

        Net (Loss) Income. The Company reported a net loss for the quarter ended
September 30,1997 of $220,596 as compared to net income of $930,791 reported for
the third quarter of the prior year. The net loss was primarily the result of a
decrease in gross margin and an increase in selling, general and administrative
expenses.


NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1996

        Gross Sales. Gross sales increased by 12.1% to $23.1 million for the
nine month period ended September 30, 1997 from $20.6 million in the same nine
month period of the prior year. Sales increased due to sales of Thomas Kemper
Soda of $2.2 million, acquired in March of 1997 and a 58.1% increase in retail
sales from $3.1 million to $4.9 million due to the opening of the Berkeley
Alehouse in February of 1997. Gross wholesale craft beer sales decreased 8.5% to
$16.1 million from $17.6 million in the same nine month period of the prior year
due to a 5.9% volume decrease and an increase in the proportion of draft beer
sales. The product mix shifted to a higher percentage of draft sales (36.9% as
of September 30, 1997 versus 31.8% as of September 30, 1996) which resulted in
lower sales dollars per barrel sold.

        Excise Taxes. Excise taxes decreased to 7.4% of net sales for the nine
month period ended September 30, 1997 from 8.5% of net sales for the same nine
month period of the prior year. The decrease in excise taxes as a percentage of
net sales was due primarily to an underestimate of the small brewers federal
excise tax credit during the same period of the prior year.

        Gross Margin. Gross margin decreased to $5.6 million for the nine month
period ended September 30, 1997 from $7.6 million for the same nine month period
of the prior year. Gross margin as a percentage of net sales declined to 25.9%
for the nine month period ended September 30, 1997 from 40.0% for the same nine
month period of the prior year. This decrease as a percentage of net sales was
due to higher fixed and semi-fixed costs, including increases in depreciation,
increased package design costs, increased freight costs incurred servicing more
distant markets and the lower gross margin associated with the increase in sales
from retail operations (primarily sales of beer, food and branded merchandise at
the Company's Alehouses). Changes in the cost of raw materials and packaging did
not, in the aggregate, have a significant impact on gross margin during either
period.

        Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased to $6.3 million, or 29.2% of net sales, for
the nine month period ended September 30, 1997 from $4.6 million, or 24.3% of
net sales, from the same nine month period of the prior year. This increase was
due primarily to the planned increase in selling and promotional expenditures
attributable to the geographic expansion of beer sales.

        Other Income. Other income decreased to $9,809 for the nine month period
ended September 30,1997 from $787,052 for the same nine month period of the
prior year. The decrease in other income was due primarily to a decrease in
interest income earned, net of bond premium amortization, from investing the net
proceeds of the initial public stock offering, which proceeds primarily were
used to finance construction of the Company's Berkeley Brewery and Alehouse,
upgrades to the Seattle Brewery and repayment of debt.

        Net (Loss) Income. The net loss for the nine month period ended
September 30, 1997 was $514,448 as compared to net income of $2.7 million
reported for the same period of the prior year.

LIQUIDITY AND CAPITAL RESOURCES

        Net cash provided by operating activities for the nine month period
ended September 30, 1997 was $1.1 million compared to a $4.4 million for the
same nine month period of the prior year. This decrease was due in part to the
net loss of $514,448 incurred for the nine month period ended September 30, 1997
versus the net income of $2.7 million for the same nine month period of the
prior year, increased levels of inventory and changes in other operating assets
and liabilities.

        At September 30, 1997, the Company had working capital of $7.3 million
compared to $10.6 million at December 31, 1996.

        Net cash provided by investing activities in the period ended September
30, 1997 was $463,412 compared to net cash used in investing activities of $10.2
million for the same period of the prior year. The cash provided by investing
activities was primarily the redemptions and sales of investments. The cash used
in investing activities in 1996 was primarily applied to the construction of the
Berkeley Brewery and Alehouse and expansion of the Seattle Brewery.

        The Company has a $15.0 million line of credit (the "Line of Credit")
with Bank of America. The Line of Credit revolves through April 30, 1999, during
which time the required payments are interest only. Borrowings under the Line of
Credit accrue interest, at the Company's option, at either the bank's prime
rate, or at 30, 60, 90 day LIBOR plus 1.0%. The Line provides for acquisition
financing with term out provisions. The Line of Credit also includes provisions
that require the Company to maintain certain financial ratios and a minimum
tangible net worth. The Company has not borrowed funds under this Line of Credit
in 1997.

        Future capital requirements will vary depending primarily on the extent
of improvements necessary for current operating facilities. Capital expenditures
through September 30, 1997 were approximately 4.7 million, which includes final
payments on the Berkeley Brewery and Alehouse, the purchase of the Thomas Kemper
Soda Company and the continued upgrading of brewery equipment and facilities in
the Company's existing breweries. While there can be no assurance that current
expectations will be realized and plans are subject to change, the Company
believes that the existing cash and investments together with cash from
operations and borrowings under the Line of Credit, will be sufficient for the
Company's working capital needs.

        The Company's future cash requirements and cash flow expectations are
closely related to its growth. The Company generally expects to meet future
financing needs through cash flow from operations and, to the extent required
and available, additional bank borrowings, industrial development bonds and
offerings of debt or equity securities.

SUBSEQUENT EVENT

        On October 29, 1997, management announced a restructuring of the
Company's marketing and brewery operations. The restructuring will include a
refocus of marketing resources on Western and Southwestern markets and the
closure of the Kalama, Washington plant. Although this marketing decision could
result in a reduction in sales volume in other markets, the Company expects to
gain increased operating efficiencies as it redistributes Kalama production
between the Seattle and Berkeley breweries. The closure of the Kalama plant will
reduce total brewing capacity to 172,000 barrels.

        The Company expects to take a one-time charge against earnings of
approximately $1.6 million in the fourth quarter ending December 31, 1997 for
write-offs related to the disposal of fixed assets, severance payments and other
plant closure costs. The restructuring of marketing and brewery operations is
expected to reduce current fixed costs and SG&A expenses by approximately $1.0
million per year commencing in 1998.

ADOPTION OF ACCOUNTING STANDARDS

        In February 1997, the Financial Standards Board issued Statement No.
128, "Earnings Per Share," (EPS) which is required to be adopted by the Company
on December 31, 1997. At that time, the Company will be required to change the
method currently used to compute net income per share. Company's will now report
basic EPS and diluted EPS in place of primary and fully diluted EPS, which were
previously reported. The impact of Statement 128 is not expected to be material.

RISK FACTORS AND FORWARD LOOKING STATEMENTS

        Certain statements contained herein are forward-looking statements that
involve a number of risks, uncertainties and factors that may cause actual
results to materially differ, including: lower than anticipated sales in new and
existing markets; increased seasonality of demand for craft beers; decreased
selling prices; increased competition; expenses and uncertainties associated
with construction and operation of new breweries and expansion of the
distribution network; increases in raw material and packaging costs; and other
risk factors as set forth in the Company's Annual Report dated December 31,
1996.
