                        NOTES TO INTERIM FINANCIAL STATEMENTS
                                  SEPTEMBER 28, 1996
                                     (Unaudited)

    1.   In the opinion of management, the accompanying unaudited financial
statements include all adjustments (consisting of only normal recurring
adjustments) that are necessary in order to make the financial statements
contained herein not misleading.  These financial statements, notes and analyses
should be read in conjunction with the financial statements for the fiscal year
ended December 30, 1995, and notes thereto, which are contained in the Company's
Annual Report on Form 10-KSB for such fiscal year.  The results for the quarter
ended September 28, 1996 are not necessarily indicative of the results that may
be expected for the entire year ending December 28, 1996.  The Company operates
on a 52/53 week fiscal year, which approximates the calendar year.

    2.   The Company leases its Carson City facility pursuant to a ten year
lease expiring in 2000. The aggregate future minimum rental commitments as of
September 28, 1996 for this lease were:

                   1996       $  38,274
                   1997         156,918
                   1998         164,760
                   1999         172,998
                   2000          88,608
                              ---------

                              $ 621,558
                              ---------

     3.   Inventories are stated at the lower of cost (determined using the
first-in, first-out method) or market.  At September 28, 1996, inventories
consisted of:

          Raw Material          $536,456
          Work-In-Process        638,795
          Finished Goods          38,252
                              ----------
                              $1,213,503
                              ----------

     4.   Plant and equipment are stated at cost and depreciated on a
straight-line basis over the estimated useful life of the assets, generally
three to eight years.

Item 2.                     Management's Discussion and Analysis
                                or Plan of Operation

     For the purposes of the following discussion, dollar amounts have
been rounded to the nearest $1,000 and all percentages have been
rounded to the nearest 1%.

     This interim report on Form 10-QSB contains certain forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934.  Actual results could differ
materially from those projected in the forward-looking statements as a result of
various factors, including the factors set forth below and under "Future
Outlook" and elsewhere in this section.  The Company has attempted to identify
forward-looking statements by placing an asterisk immediately following the
sentence or phrase containing the forward-looking statement(s).

RESULTS OF OPERATIONS

     Net revenues for the quarter ended September 28, 1996 increased 60% from
net revenues for the quarter ended September 30, 1995.  Net revenues for the
quarter ended September 28, 1996 were $2,095,000, as compared to $1,309,000 for
the quarter ended September 30, 1995. Net revenues for the nine months ended
September 28, 1996 increased 92% to $6,761,000 from net revenues for the nine
months ended September 30, 1995 of $3,530,000.  A majority of this increase in
revenues for both the quarter and nine months ended September 28, 1996 is
attributable to product shipments to Chesapeake Sciences Corporation.

     The Company's backlog of customer orders was $5,181,000 at September 28,
1996 as compared to $8,554,000 at September 30, 1995, and $7,912,000 at December
30, 1995.  Approximately $2,400,000 of the total backlog at September 28, 1996
is currently scheduled for shipment during the fourth quarter of 1996, with the
balance scheduled to ship in 1997.* Approximately $1,440,000, or 28%, of the
total backlog relates to orders from the Company's largest customer, Chesapeake
Sciences Corporation, which accounted for approximately 53% and 68%,
respectively, of the Company's net revenues during the quarter and nine months
ended September 28, 1996.  Because customers may place orders for delivery at
various times throughout the year, and due to the possibility of customer
changes in delivery schedules or cancellation of orders with little or no
penalty, the Company's backlog as of any particular


                                       7
<PAGE>

date may not be indicative of actual future sales.*  For example, Chesapeake 
notified the Company in July, 1996 that it wanted to stretch out the delivery 
schedule for products previously ordered from the Company.  As a result, 
approximately $500,000 of product scheduled for delivery in the third quarter 
of 1996 has been rescheduled for delivery in the fourth quarter of 1996 and 
the first part of 1997.

     Cost of sales was $1,407,000, or 67% of net revenues, for the quarter ended
September 28, 1996, as compared to $874,000, or 67% of net revenues, for the
quarter ended September 30, 1995.  Cost of sales for the nine months ended
September 28, 1996 was $4,591,000, or 68% of net revenues, as compared to
$2,468,000, or 70% of net revenues for the nine months ended September 30, 1995.
The increase in cost of sales for the quarter and nine month period on an
absolute dollar basis reflects the increased amounts of sales over the prior
year's quarter and nine month period.  The decrease in cost of sales as a
percentage of net revenues for the nine month period is primarily a result of
the increase in net revenues, which spread fixed costs over a higher revenue
base.

     Research and development expenses were $172,000, or 8% of net revenues, for
the quarter ended September 28, 1996, as compared to $143,000, or 11% of net
revenues, for the quarter ended September 30, 1995.  Research and development
expenses for the nine months ended September 28, 1996 were $461,000, or 7% of
net revenues, as compared to $454,000, or 13% of net revenues, for the nine
months ended September 30, 1995.  The increase in the dollar amount of research
and development expenses for the quarter and  nine months ended September 28,
1996, as compared to the quarter and nine months ended September 30, 1995, is
primarily attributable to increased compensation costs resulting from hiring of
additional  personnel required for engineering programs.  The decrease in
research and development expenses as a percentage of net revenues is the result
of spreading these costs over a higher sales volume.

     Selling, general and administrative expenses were $153,000, or 7% of net
revenues, for the quarter ended September 28, 1996, as compared to $126,000, or
10% of net revenues in the quarter ended September 30, 1995. Selling, general
and administrative expenses for the nine months ended September 28, 1996 were
$470,000, or 7% of net revenues, as compared to $372,000, or 11% of net
revenues, for the nine months ended September 30, 1995.  The increase  in the
dollar amount of selling, general and administrative expenditures for the
quarter and nine months ended September 28, 1996 is mainly attributable to
increased compensation costs resulting from changes in the mix of personnel,
increased advertising and


                                       8
<PAGE>

sales promotion expenses and increased public-relations and shareholder 
related expenses. The decrease in selling, general and administrative 
expenses as a percentage of net revenues is the result of spreading these 
costs over a higher sales volume.

     The Company had an operating profit of $364,000 for the quarter ended
September 28, 1996, as compared to an operating profit of $167,000 for the
quarter ended September 30, 1995.  The improvement in quarterly operating
results was primarily attributable to increased net revenues.  The Company had
an operating profit of $1,238,000 for the nine months ended September 28, 1996,
as compared to an operating profit of $237,000 for the nine months ended
September 30, 1995.  This change was primarily due to significantly increased
revenues and improved gross margin during the first nine months  of 1996.

     There was no provision for income taxes in the third quarter of 1996 as the
Company has net operating loss carryforwards for both Federal and California
income tax purposes.  The net operating loss carryforwards will eliminate the
need for any significant provision for income taxes in the foreseeable future.*
The Company accounts for deferred income taxes under the method prescribed by
Financial Accounting Standards Board Statement No. 109, "Accounting for Income
Taxes".


LIQUIDITY AND CAPITAL RESOURCES

     The Company had $723,000 in cash at September 28, 1996, as compared to
$93,000 at December 30, 1995.   This increase of $630,000 from year end is
comprised of $744,000 provided by operating activities and $49,000 in proceeds
from the exercise of stock options,  partially offset by $164,000 used for the
purchase of capital equipment .   Cash generated by operating activities is
primarily attributable to net income, partially offset by increases in accounts
receivable and decreases in accounts payable.

     Accounts receivable were $1,482,000 at September 28, 1996, as compared to
$1,180,000 at December 30, 1995.  This increase is the result of an increase in
sales volume in the quarter ended September 28, 1996 as compared to the quarter
ended December 30, 1995.

     Inventories were $1,214,000 at September 28, 1996, as compared to
$1,240,000 at December 30, 1995.  Inventories have not increased from year end
in spite of higher levels of product shipments.


                                       9
<PAGE>

     Prepaid expenses and deposits were $35,000 at September 28, 1996 as
compared to $32,000 at December 30, 1995.  This increase reflects normal ongoing
business transactions.

     Accounts payable were $279,000 at September 28, 1996, as compared to
$674,000 at December 30, 1995.  This decrease is primarily the result of
improved cash flow allowing more timely payments by the Company to its
suppliers.

     Accrued employee compensation and benefits were $293,000 at September 28,
1996, as compared to $191,000 at December 30, 1995.  This increase is partially
attributable to a slight increase in the number of employees during the year
combined with increased accruals for employee profit sharing resulting from
higher earnings.

     Commissions and other accrued liabilities were $98,000 at September 28,
1996, as compared to $130,000 at December 30, 1995. This reduction is primarily
the result of a reduction in accrued liabilities due to payments made in 1996 of
certain expenses accrued in 1995.

     Customer pre-payments increased to $245,000 at September 28, 1996 as
compared to $179,000 at December 30, 1995, as the Company continues to negotiate
for prepayments in situations requiring significant investment in inventories
combined with extended delivery schedules.

FUTURE OUTLOOK

      Cash flow for the nine months ended September 28, 1996 has been  positive
and the Company has increased its working capital during this period by
$1,167,000.  This increase in working capital consists primarily of cash and
accounts receivable together with an overall reduction of current liabilities,
primarily accounts payable. The Company had no amount outstanding on its
$100,000 credit line with Sierra West Bank at September 28, 1996, and was in
compliance with all of the covenants of the loan agreement. The Company believes
that operations and its existing credit line will provide sufficient cash to
meet operating needs over the next twelve months.*  However, since the Company
desires to expand its technological base and increase its offering of standard
products, investments in resources requiring new equity or debt financing may be
required.*  In such case, there can be no assurance that such financing will be
available on terms acceptable to the Company or at all.

     While the Company's backlog of unfilled orders has decreased during the
nine months ended September 28, 1996, backlog has actually increased slightly
from the previous quarter.  The Company continues to receive additional orders
from existing customers and has also added new customers during the past
quarter.  Chesapeake Sciences still remains the largest single portion of the
Company's current backlog (28% as of September 28, 1996).   In addition,
Chesapeake accounted for approximately 53% and 68%, respectively, of net
revenues for the quarter and nine months ended September 28, 1996. Therefore,
any further rescheduling or cancellations of orders from Chesapeake would have a
material adverse effect on the Company's future results of operations.  The
Company still anticipates additional orders for the Chesapeake products and
expects that such orders will be placed during the fourth quarter of 1996.*
However, until such additional orders are shipped to Chesapeake, the risk exists
that current levels of revenue and earnings could decline in the future.*
