5.  THOMAS KEMPER SODA COMPANY ACQUISITION:

     In March 1997, the Company acquired substantially all of the operating
assets and assumed certain liabilities of Thomas Kemper Soda Company, a
manufacturer of premium sodas located in Seattle, Washington. The total purchase
price was $1,700,000. The purchase price was paid with approximately $562,000 in
cash during the first quarter of 1997, approximately $14,000 in cash during the
second quarter of 1997 and the assumption of approximately $1,138,000 of
liabilities at the date of acquisition. The acquisition was accounted for using
the purchase method of accounting. Accordingly, the purchased assets and assumed
liabilities were recorded at their estimated fair value at the date of
acquisition. The excess purchase price over the estimated fair values of the
assets acquired was $802,513 and will be amortized over 10 years. The results of
the acquired business have been included in the statement of income since the
date of acquisition.

6.  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.

QUARTER ENDED SEPTEMBER 30, 1998 COMPARED TO QUARTER ENDED SEPTEMBER 30, 1997

     Gross Sales. Gross sales decreased by 15.1% to $7,184,000 for the third
quarter ended September 30, 1998 from $8,466,000 in the same quarter of the
prior year. The decrease resulted primarily from a 23.9% decrease in wholesale
craft beer sales to $4,377,000 for the third quarter of 1998 from $5,749,000 in
the same quarter of the prior year due mainly to a 21.6% volume decrease and an
increase in the proportion of draft beer sales. The product mix shifted to a
higher percentage of draft sales (38.8% for the quarter ended September 30, 1998
versus 35.1% for the same quarter of the prior year) which resulted in lower
sales dollars per barrel sold.  Depletions by the company's wholesalers were
down less than the decline in shipments in the quarter and management believes
that a significant portion of the decline in shipments is accounted for by
inventory adjustments downstream.

     Excise Taxes. Excise taxes decreased to 6.3% of net sales for the third
quarter ended September 30, 1998 from 7.3% of net sales in the same quarter of
the prior year. The decrease in excise taxes as a percentage of net sales was
due to a lower average federal excise tax rate during the quarter ended
September 30, 1998.

     Gross Margin. Gross margin decreased to $1,568,000 for the third quarter
ended September 30, 1998 from $1,943,000 in the same quarter of the prior year.
Gross margin as a percentage of net sales declined to 23.2% for the third
quarter ended September 30, 1998 from 24.6% for the same quarter of the prior
year. This decrease as a percentage of net sales was due primarily to the
application of certain fixed and semi-fixed costs to the lower level of sales
volume.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased to $1,982,000, or 29.3% of net sales, for the
third quarter ended September 30, 1998 from $2,086,000, or 26.4% of net sales,
for the same quarter of the prior year. This decrease resulted from the
decision, made last year, to refocus marketing resources on the West Coast. The
savings were offset in the current quarter by non-recurring costs related to the
upgrading of the company's computer systems, legal expenses and other expenses.

     Other Income (Expense), net. The Company incurred other income (net of
other expense) of $95,000 for the third quarter ended September 30, 1998 as
compared to other expense of $121,000 reported for the third quarter of the
prior year. The increase in other income was due primarily to the elimination of
bond premium amortization expense during 1997.

     Net Loss. The Company reported a net loss for the quarter ended September
30, 1998 of $235,000 as compared to a net loss of $221,000 reported for the
third quarter of the prior year. The increase in net loss was primarily the
result of the decrease in gross margin and non-recurring charges including legal
expenses, computer software costs and other one-time adjustments.

NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1997

     Gross Sales. Gross sales decreased by 9.6% to $20,903,000 for the nine
month period ended September 30, 1998 from $23,114,000 in the same nine month
period of the prior year. This decrease was partially offset by increased sales
of Thomas Kemper Sodas, acquired in March of 1997, to $2,826,000 from $2,157,000
for the same nine month period of the prior year. Gross wholesale craft beer
sales decreased 17.0% to $13,332,000 from $16,072,000 for the same nine month
period of the prior year due to a 16.6% volume decrease and an increase in the
proportion of draft beer sales. The product mix shifted to a higher percentage
of draft sales (37.8% as of September 30, 1998 versus 36.9% as of September 30,
1997) which resulted in lower sales dollars per barrel sold.

     Excise Taxes. Excise taxes decreased to 6.5% of net sales for the nine
month period ended September 30, 1998 from 7.4% 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 lower average federal excise tax rate resulting
from lower beer barrels shipped during the nine month period ended September
30, 1998 and a greater proportion of restaurant and soda sales which do not bear
excise tax.

      Gross Margin. Gross margin decreased to $4,500,000 for the nine month
period ended September 30, 1998 from $5,571,000 for the same nine month period
of the prior year. Gross margin as a percentage of net sales declined to 22.9%
for the nine month period ended September 30, 1998 from 25.9% for the same nine
month period of the prior year. This decrease as a percentage of net sales was
due primarily to the application of certain fixed and semi-fixed costs to the
lower level of sales volumes.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased to $6,164,000, or 31.4% of net sales, for the
nine month period ended September 30, 1998 from $6,287,000, or 29.2% of net
sales, for the same nine month period of the prior year. This decrease resulted
from the decision, made last year, to realign operations and refocus marketing
resources to the West Coast. The savings were offset in the current year by non-
recurring costs related to the upgrading of the company's computer system, legal
expenses and other expenses.

     Other Income.  Other income increased to $504,00 for the nine month period
ended September 30,1998 from $10,000 for the same nine month period of the prior
year. The increase in other income was due primarily to the successful outcome
of a long-standing securities lawsuit which resulted in the Company's insurers
refunding expenditures on legal costs of $250,000 in the second quarter ended
June 30, 1998 and the elimination of bond premium amortization expense during
1997 of $289,000.

     Net Loss.  The net loss for the nine month period ended September 30, 1998
was $797,000 as compared to $514,000 reported for the same nine month period of
the prior year. The increase in net loss was primarily the result of a lower
gross margin from wholesale beer sales, computer software costs and other non-
recurring charges.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by operating activities for the nine month period ended
September 30, 1998 was $1,365,000 compared to $1,088,000 for the same nine month
period of the prior year. At September 30, 1998, the Company had working capital
of $6,647,000 compared to $6,499,000 at December 31, 1997.

     Net cash used in investing activities for the period ended September 30,
1998 was $801,000 compared to net cash provided by investing activities of
$463,000 for the same period of the prior year. The cash used in investing
activities in 1998 included the purchase of system software and completion of
the installation of soda production equipment at the Berkeley Brewery. Cash
provided by investing activities during 1997 was primarily redemptions and sales
of investments.

     The Company has a $15,000,000 line of credit (the Line of Credit) for 
short-term operating needs. The Line of Credit revolves through April 30, 1999, 
during which time the payments are interest only. At that date, any outstanding
balance will be due in full. Borrowings under the Line of Credit will accrue
interest, at the Company's option, at either the bank's prime rate or at LIBOR
plus 100 basis points. Up to $5,000,000 of the line of credit may be used to
finance acquisitions. Amounts used to finance acquisitions may be converted to a
four-year fully amortizing term loan, with an additional option to fix the rate
of interest at the bank's prime rate plus 125 basis points.

     Future capital requirements may vary depending on such factors as the cost
of acquisition of businesses, brands and real estate in the markets selected for
future expansion. Capital expenditures through September 30, 1998 were
approximately $1,043,000 which includes installation of soda equipment in the
Berkeley brewery, upgrading of brewery equipment and facilities in the Seattle
Brewery and the installation of a new computer system. While there can be no
assurance that current expectations will be realized and plans are subject to
change upon further review, the Company believes that its cash reserves,
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 expansion plans. The Company generally expects to meet
future financing needs through cash on-hand, cash flow from operations and, to
the extent required and available, additional bank borrowings.

     The year 2000 issue is the result of computer programs being written using 
two digits rather than four digits to define the applicable year. Any of the 
Company's computer programs that have time-sensitive software may recognize a 
date using "00" as the year 1900 rather than the year 2000. If not addressed, 
the direct result could be a system failure or miscalculations causing 
disruptions of operations, including, among other things, a temporary inability 
to process customer transactions or engage in similar normal business 
activities.

     The Company's Year 2000 Project is proceeding on schedule. Early in 1998, 
the Company began a project to improve its information systems by replacing 
existing business software. The new system replaces all critical systems and 
approximately 90% of all computer systems which the Company's inventory showed 
to be affected by the year 2000 issue. The Company's inventory revealed no other
significant problems arising from non-compliant computer chips embedded in other
equipment. The total cost of the Company's Year 2000 Project is in the area of 
$600,000, including the cost of installing the business software. Approximately 
$320,000 has been incurred as of September 30, 1998 and the project is expected 
to be completed by mid-1999.

     The Company is dependent upon certain suppliers and its wholesale 
customers. There are plans to communicate with these companies to assess their 
readiness for the year 2000. Contingency plans will be made where practicable to
cope with interruption of supplies or services and failures by wholesalers to 
properly service the Company's markets. However, it should be noted that there 
are many cases, such as utility supply and servicing of remote markets, where no
feasible alternatives are available to the Company and the Company is vulnerable
to failures by external third parties.

     Although management anticipates that its systems and applications will be 
year 2000 compliant on a timely basis, there can be no assurance that the 
systems of other companies on which the Company's systems rely will be year 2000
compliant in the same time frame. Any such failure on the part of other 
companies with whom the Company transacts business, to be year 2000 compliant on
a timely basis, may have an adverse impact on the operations of the Company.
