                     Notes to Condensed Financial Statements
                                   (Unaudited)

(1)      BUSINESS AND CURRENT EVENTS

     As described in more detail in note 3 of the financial statements, the
Company has decided to enter into the retail market as a provider of newly
developed, innovative equipment. The Company began development of the equipment
and incurred formation costs during the current quarter in anticipation of the
transaction, which closed on April 7, 2004.

(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
---------------------

     The accompanying unaudited condensed financial statements of the Company
have been prepared in accordance with Rule 10-01 of Regulation S-X promulgated
by the Securities and Exchange Commission and, therefore, do not include all
information and footnotes necessary for a fair presentation of financial
position, results of operations and cash flows in conformity with accounting
principles generally accepted in the United States of America. In the opinion of
the Company, however, the accompanying unaudited condensed financial statements
contain all adjustments, consisting only of normal recurring adjustments,
necessary to present fairly the Company's financial position as of March 31,
2004, its results of operations for the three-month periods ended March 31, 2004
and 2003, and its cash flows for the three month periods ended March 31, 2004
and 2003, respectively. The results of operations of the Company for the
three-month period ended March 31, 2004 may not be indicative of future results.
These condensed unaudited financial statements should be read in conjunction
with the financial statements and notes thereto included in the Company's annual
report on Form 10-K for the year ended December 31, 2003 as filed with the
Securities and Exchange Commission on March 30, 2004.

Earnings Per Common Share
-------------------------

     The Company calculates net loss per share in accordance with SFAS No. 128,
Earnings Per Share. Under SFAS No. 128, basic net earnings (loss) per common
share is calculated by dividing net earnings (loss) by the weighted-average
number of common shares outstanding during the reporting period. Diluted net
earnings (loss) per common share reflects the effects of potentially dilutive
securities where the effect of inclusion of such securities would not be
anti-dilutive. Weighted average shares used to compute net loss per share are
presented below (in thousands):

     Options to purchase 166,000 and 233,000 shares of potentially dilutive
common stock were excluded from the calculation of diluted net loss per share
for the three months ended March 31, 2004 and 2003 respectively, because the
effects of these instruments were anti-dilutive.

Industrial Development Bonds
----------------------------

     The Company maintains a letter of credit from its bank in support of the
$2,800,000 industrial development bonds, which are secured by substantially all
the assets of the Company. The bonds accrue interest at a variable monthly rate,
and interest was paid at a weighted-average variable rate of 1.05% during the
quarter ending March 31, 2004. On February 1, 2002, the Company paid $1,500,000
to redeem a portion of the industrial development bonds utilizing the restricted
cash balance of $1,452,000 plus an additional $48,000 of unrestricted cash.
Effective March 1, 2002, the Company began making required monthly payments of
$10,000 per month into a sinking fund (restricted cash) for redemption of the
bonds. Redemption will occur in minimum increments of $100,000 as the funds
accrete to the minimum redemption level. The terms of the Reimbursement
Agreement require the Company to make annual payments of $100,000 during 2003
and 2004, and the balance of $2,700,000 in 2005. The first payment of $100,000
was made on January 21, 2003, and the second payment of $100,000 was made on
January 13, 2004.

     The Company's stand-by letter of credit reimbursement agreement with its
bank contains certain affirmative financial covenants. At March 31, 2004, the
Company was not in compliance with the tangible net worth and debt service
covenants. The Company received waivers relating to these covenants through
September 30, 2004. The Company has made all required debt service payments on
the bonds. However, based on the uncertainty concerning the Company's ability to
meet the covenant after the waiver expires, and considering that a covenant
violation would constitute an event of default and allow the bank to call the
debt prior to maturity, the entire industrial development bonds balance has been
classified as a current liability in the accompanying balance sheets.

     The inability of the Company to return to profitability could result in a
default under the terms of the Union Bank of California Reimbursement Agreement,
which supports the stand-by letter of credit guaranteeing the Company's
performance on the industrial development bonds. In the event the Company
defaults and is unable to present a viable turn-around plan satisfactory to its
bank, such event could cause the bank to require the Company to seek a
substitute guarantor, re-finance the building with alternative financing or sell
the San Marcos, California facility. The inability of the Company to
successfully substitute a guarantor or to re-finance the building could have a
materially adverse effect on the Company's business. The Company will continue
to seek waivers for any covenant violations in the future until a modification
of the covenants can be negotiated.

     In the event the bank chooses to no longer forbear, management would
consider several options which include utilizing some portion of cash,
refinancing the building with alternative financing, a sale-leaseback or sale of
the San Marcos, California facility and relocation to a leased facility.
Management believes that it has the ability to execute its alternate plans in
the event that repayment of the Company's industrial development bonds would be
required in the next 12 months, and the Company would have adequate finances to
fund its operating, investing and financing activities during the next 12 months
under either scenario for repayment of its industrial development bonds.

w
Product Warranty Information


     The Company provides for the estimated cost of product warranties at the
time revenue is recognized. While the Company engages in extensive product
quality programs and processes, including actively monitoring and evaluating the
quality of its component suppliers, the Company's warranty obligation is
affected by product failure rates and the related material usage, field service
and delivery costs incurred in correcting a product failure. Should actual
product failure rates, material usage, or service delivery costs differ from the
Company's estimates, revisions to the estimated warranty liability would be
required.

     Warranty cost and accrual information is as follows for the three months
ended Mar. 31, 2004 and 2003:

Stock-Based Compensation
------------------------

     In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based
Compensation -- Transition and Disclosure", which amended SFAS No. 123,
"Accounting for Stock-Based Compensation." The new standard provides alternative
methods of transition for a voluntary change to the fair market value based
method for accounting for stock-based employee compensation. Additionally, the
standard amends the disclosure requirements of SFAS No. 123 to require prominent
disclosures in both annual and interim financial statements about the method of
accounting for stock-based employee compensation and the effect of the method
used on reported results. This standard was effective for financial statements
for the year ended December 31, 2002. In compliance with SFAS No. 148, the
Company has elected to continue to follow the intrinsic value method in
accounting for its stock-based employee compensation plan as defined by APB No.
25 and has made the applicable disclosures below.

     Had the Company determined employee stock based compensation cost based on
a fair value model at the grant date for its stock options under SFAS 123, the
Company's net loss per share would have been adjusted to the pro forma amounts
for the three months ended March 31, 2004 and 2003 as follows ($ in thousands,
except per share amounts):

                                   (Unaudited)

(3)      SUBSEQUENT EVENT

     The Company incorporated a new subsidiary, Distributed Delivery Networks
Corporation ("ddn") on February 3, 2004, through which it plans to market and
install newly developed, innovative equipment for use by retail stores.

     ddn was capitalized with $255 from the Company and the two third parties
(one is now an employee of ddn and the other retained as a consultant -
hereafter called "ddn Founders") in exchange for common stock. On April 7, 2004,
the Company and the ddn Founders entered into definitive agreements related to
the ownership and management of ddn, and commenced business on that day. The ddn
Founders purchased a 49% restricted interest in ddn. The restrictions lapse
ratably over a thirty-six month period. The Company retains a repurchase right,
in the event of termination of the ddn Founders as employees or as consultants,
under certain conditions, which also lapses ratably over the thirty-six month
period. The Company plans to retain an appraisal firm during the second quarter
of 2004 for the purpose of obtaining a valuation of ddn as of April 7, 2004 to
determine compensation expense, if any, to the ddn Founders for any excess of
value received over the purchase price of their shares.

     The Company will finance the subsidiary's operations with a $1,300,000
loan. The loan is unsecured, with a term of ten years, at an interest rate of
4.61% with payments beginning on April 7, 2008. On such date, all accrued
interest will be added to the principal amount outstanding. That balance shall
be repaid in seventy-two (72) substantially equal monthly installments beginning
on April 7, 2008 and continuing until April 7, 2014, when the entire outstanding
balance will be due and payable in full.

     Due to the lack of substantial capitalization by the ddn Founders, the
Company will bear 100% of the losses of ddn and as a result bears significant
risk of loss of the principal and accrued interest related to the aforementioned
loan.

     The loan agreement provides for a bonus to the ddn Founders equal to the
interest accrued on the note and a redemption option exercisable by the Company
during the six-month period beginning April 7, 2004 by which the Company has a
right to redeem its shares and require repayment of the note if certain
performance conditions are not met.

     The Company has also entered into a manufacturing and development agreement
with ddn to develop and manufacture the equipment.

     ddn is a newly formed start up company and is subject to the general risks
and uncertainties associated with a start-up enterprise, including the
substantial risk of business failure.

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

Forward Looking Statements
--------------------------

     This Quarterly Report contains forward-looking statements within the
meaning of the Private Securities Reform Act of 1995, particularly statements
regarding market opportunities, customer acceptance of products, gross margin
and marketing expenses. These forward-looking statements involve risks and
uncertainties, and the cautionary statements set forth below identify important
factors that could cause actual results to differ materially from those in any
such forward-looking statements. Such factors include, but are not limited to,
adverse changes in general economic conditions, including changes in the
specific markets for the Company's products, product availability, decreased or
lack of growth in the electronics industry, adverse changes in customer order
patterns, increased competition, lack of acceptance of new products, pricing
pressures, lack of success in technological advancements, risks associated with
foreign trade and other factors.

                              RESULTS OF OPERATIONS

FIRST QUARTER 2004 COMPARED TO FIRST QUARTER 2003

Net Sales
---------

     Net sales for the three months ended March 31, 2004 were $3,056,000
compared to $2,769,000 for the same period in the prior year, an increase of
10.4%. The sales growth primarily was from an increase in AIA sales.

     During the current quarter, the Amistar Industrial Automation ("AIA")
division shipped three of its DataPlace 100LP machines, three of its DataPlace
SBL machines, and two of its distributed circuit board assembly machines,
compared to one DataPlace 1M machine and one DataPlace SBL machine sold during
the first quarter of 2003.

     Sales of distributed circuit board assembly machine accessories and spare
parts grew 460% over the first quarter of 2003, from $80,000 to $448,000, as the
Company sold two machines during the first quarter of 2004 compared to no sales
during the first quarter of 2003.

     Sales of AIA custom factory automation and other products in the first
quarter of 2004 primarily included two minor specialty machines and machine shop
services similar to the first quarter of 2003. The AIA division has in
production four custom engineered machines to fulfill contracts received from
customers doing business in the eyeglass lens, RF identification, landscaping
products, and medical optical manufacturing industries.

     The Amistar Manufacturing Services division ("AMS") sales declined 13.7% to
$1,846,000 for the three months ended March 31, 2004, from $2,140,000 for the
same period in 2003 primarily due to reduced orders from two major customers,
one of which, the Company expects to lose to an out-of-state manufacturing
services provider.

Gross Profit
------------

     Gross profit decreased $19,000, or 3%, to $529,000 during the quarter ended
March 31, 2004 compared to $548,000 in the same period in 2003. This decrease
was due primarily to the decline in AMS sales and partially offset by the
increase in AIA sales.

                        Results of Operations, Continued

Selling Expenses
----------------

     Selling expenses increased 11% in the current quarter from the first
quarter of 2003, from $331,000 to $367,000 primarily due to commissions accrued
on increased machine sales.

General and Administrative Expenses
-----------------------------------

     The general and administrative expenses increased 57%, from $252,000 in the
first quarter of 2003 to $395,000 in the first quarter of 2004 primarily due to
ddn formation costs.

Engineering, Research and Development Expenses
----------------------------------------------

     Engineering, research and development expenses increased 9% in the current
quarter over the same period in 2003, from $107,000 to $117,000. The primary
utilization of the engineering staff has been in support of custom factory
engineering design activities and development of the new ddn machine. The
engineering group provided billable engineering design services and allocated
$30,000 in engineering labor costs to work-in-process inventory and $43,000 to
cost of sales related to design contracts, most of which is expected to be
complete in the second quarter of 2004. During the quarter, costs of $82,000
were incurred related to development of the first ddn machine.

Income Taxes
------------

     The $1,000 provision represents the Company's minimum tax liability to
various states.

     A 100% valuation allowance was recorded against deferred tax assets.

                         LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash provided from operating activities was $228,000 for the
three months ended March 31, 2004, a $216,000 decrease over the cash provided
from operating activities of $444,000 for the three months ended March 31, 2003.
The decline was due to the increased loss, which included ddn formation and
development costs, increased investments in AMS assembly equipment and partially
offset by a greater increase in accounts payable and a greater decrease in
prepaid expenses.

     The Company maintains a letter of credit from its bank in support of the
$2,800,000 industrial development bonds, which are secured by substantially all
the assets of the Company. The bonds accrue interest at a variable monthly rate,
and interest was paid at a weighted-average variable rate of 1.05% during the
quarter ending March 31, 2004. On February 1, 2002, the Company paid $1,500,000
to redeem a portion of the industrial development bonds utilizing the restricted
cash balance of $1,452,000 plus an additional $48,000 of unrestricted cash.
Effective March 1, 2002, the Company began making required monthly payments of
$10,000 per month into a sinking fund (restricted cash) for redemption of the
bonds. Redemption will occur in minimum increments of $100,000 as the funds
accrete to the minimum redemption level. The terms of the Reimbursement
Agreement require the Company to make annual payments of $100,000 during 2003
and 2004, and the balance of $2,700,000 in 2005. The first payment of $100,000
was made on January 21, 2003, and the second payment of $100,000 was made on

                                       15

                   Liquidity and Capital Resources, continued

January 13, 2004. The Company's stand-by letter of credit reimbursement
agreement with its bank contains certain affirmative financial covenants. At
March 31, 2004, the Company was not in compliance with the tangible net worth
and debt service covenants. The Company received waivers relating to these
covenants through September 30, 2004. The Company has made all required debt
service payments on the bonds. However, based on the uncertainty concerning the
Company's ability to meet the covenant after the waiver expires, and considering
that a covenant violation would constitute an event of default and allow the
bank to call the debt prior to maturity, the entire industrial development bonds
balance has been classified as a current liability in the accompanying balance
sheets.

     The inability of the Company to return to profitability could result in a
default under the terms of the Union Bank of California Reimbursement Agreement,
which supports the stand-by letter of credit guaranteeing the Company's
performance on the industrial development bonds. In the event the Company
defaults and is unable to present a viable turn-around plan satisfactory to its
bank, such event could cause the bank to require the Company to seek a
substitute guarantor, re-finance the building with alternative financing or sell
the San Marcos, California facility. The inability of the Company to
successfully substitute a guarantor or to re-finance the building could have a
materially adverse effect on the Company's business. The Company will continue
to seek waivers for any covenant violations in the future until the Company
returns to profitability and a modification of the covenants can be negotiated.

     In the event the bank chooses to no longer forbear, management would
consider several options which include utilizing some portion of cash,
refinancing the building with alternative financing, a sale-leaseback or sale of
the San Marcos, California facility and relocation to a leased facility.
Management believes that it has the ability to execute its alternate plans in
the event that repayment of the Company's industrial development bonds would be
required in 2004 or in 2005 prior to December 1, 2005, and the Company would
have adequate finances to fund its operating, investing and financing activities
through 2004 and 2005 under either scenario for repayment of its industrial
development bonds.

     Management believes that as a result of the reduction in the loss in 2003
compared to 2002 and the achievement of positive operating cash flow (defined as
net loss plus depreciation and amortization) for 2003, although the Company
increased its loss in the current quarter over the same quarter in 2003, the
bank's comfort in the Company's ability to continue as a viable company and
service its debt has improved greatly and that the bank more than likely will
continue to forbear until December 1, 2005 when the bond term expires. The
Company expects to refinance the building when the bonds come due in December
2005, with a conventional fully amortized loan from a new lender at rates in
line with the current market for such a loan.

     During April 2004, the Company made a $1,300,000 loan from existing cash on
hand to ddn to fund machine development and start-up operations. The Company
expects ddn to expend approximately $1,200,000 of this amount during 2004. While
the Company's cash position will decrease significantly as a result of
utilization of the loan proceeds, the Company believes it will have sufficient
remaining cash on hand to fund its operations. The Company's $1,300,000 loan to
ddn to fund the new venture is subject to significant risks and uncertainties of
success while ddn executes its plan to market newly developed, innovative
equipment for use by retail stores.

     The Company's primary sources of liquidity consist of cash and cash
equivalents and working capital. If the bank continues to grant waivers on the
irrevocable letter of credit reimbursement agreement, the Company believes that
its cash and cash equivalents provided from operations and cash and cash
equivalents balances at March 31, 2004 will be adequate

                   Liquidity and Capital Resources, continued

to support its operating, investing and financing requirements for the next
twelve month period. In the event the bank chooses to forebear no longer,
management would consider several options which include utilizing some portion
of cash, re-financing the SanMarcos, California building with alternative
financing, a sale-leaseback or saleof the San Marcos, California facility and
relocation to a leased facility.Management believes that it has the ability to

Bonds.
