Financial Statements should be read in conjunction with the Financial Statements
and notes thereto for the years ended December 31, 1996 and 1995, included in

NOTE 3 - RELATED PARTY TRANSACTIONS

In April, 1997, the Company amended the March 1996 agreement with one of its
shareholders to increase the total amount to be received upon issuance of
subordinated convertible debentures to $4,430,000. Through June 30, 1997, the
Company has received $3,730,000 pursuant to such agreement. The Company will
receive the remaining $700,000 in installments during the remainder 1997 in
exchange for subordinated convertible debentures. The debentures will convert to
preferred stock at September 30 and December 31, 1997 in amounts to be
determined at a price per share based on the closing bid price of the Company's
Common Stock on the last day of the calendar quarter.

NOTE 4 - RECENT ACCOUNTING  PRONOUNCEMENT

In February, 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128 ("FAS 128"), "Earnings per Share." This
statement redefines earnings per share under generally accepted accounting
principles. Under the new standard, primary earnings per share is replaced by
basic earnings per share and fully diluted earnings per share is replaced by
diluted earnings per share. The Company is required to adopt the new standard in
the fourth calendar quarter of 1997. The following table sets forth primary
earnings per share as reported and unaudited pro forma basic and diluted
earnings per share assuming FAS 128 had been applied during the periods
presented:

                                OTHER INFORMATION


Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

This Form 10-Q contains certain forward looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities Act
of 1934 and the Company intends that such forward-looking statements are subject
to the safe harbors created thereby. These forward-looking statements include
(i) the existence and development of the Company's technical and manufacturing
capabilities, (ii) anticipated increased sales, (iii) potential future decreases
in manufacturing costs, and (iv) the need for, and availability of, additional
financing.

The forward-looking statements included herein are based on current expectations
that involve a number of risks and uncertainties. These forward-looking
statements are based on assumptions regarding the Company's business, which
involve judgments with respect to, among other things, future economic,
competitive and market conditions, and future business decisions, all of which
are difficult or impossible to predict accurately and many of which are beyond
the control of the Company. Although the Company believes that the assumptions
underlying the forward-looking statements are reasonable, any of the assumptions
could prove inaccurate and, therefore, there can be no assurance that the
results contemplated in forward-looking statements will be realized. In
addition, the business and operations of the Company are subject to substantial
risks which increase the uncertainty inherent in such forward-looking statements
(see "Additional Factors that May Affect Future Operating Results" on page 5 of
the Company's Annual Report on Form 10-K for the year ended December 31, 1996).
In light of the significant uncertainties inherent in the forward-looking
information included herein, the inclusion of such information should not be
regarded as a representation by the Company or any other person that the
objectives or plans of the Company will be achieved.

Results of Operations

For the three and six months ended June 30, 1997, the Company had sales of
$2,146,000 and $3,847,000, respectively, compared to sales of $1,705,000 and
$3,107,000 for the three and six month periods ended June 30, 1996. This
increase was primarily due to sales to an expanded customer base as a result of
an increase in the Company's direct sales personnel. The general sales cycles
for distribution of the Company's products are similar to those of most
businesses selling products designed for use as part of large systems, and range
from three to six months for Value Added Resellers and small System Integrators
and from one to two years for Original Equipment Manufacturers, Product
Integrators and large System Integrators.

Cost of sales, as a percentage of sales, was 75% and 79% for the three and six
month periods ended June 30, 1997, respectively, as compared to 85% and 90% for
the comparable 1996 periods. Although gross margin has improved in 1997 as
compared to 1996, the Company's relatively low gross margins reflected the
Company's low levels of net sales, which have resulted in unabsorbed
manufacturing costs and high costs of materials due to the inability to achieve
purchasing economies of scale. The Company expects that, as product sales
continue to increase, costs of sales per unit of product will decrease because
fixed manufacturing costs will be distributed over the larger sales volume, and
material costs will decrease as the result of volume purchases.

For the three and six month periods ended June 30, 1997, research and
development expenses were $338,000 and $658,000, respectively, compared to
$347,000 and $630,000 for the comparable periods of 1996. Research and
Development expenses have remained relatively flat for the three and six months
ended June 30, 1997 as compared to the comparable 1996 periods due to the
Company's cost containment programs. The Company believes that research and
development expenses will continue to increase moderately in 1997 due to current
projects under consideration.

Marketing and sales expenses were $529,000 and $909,000 for the three and six
month periods ended June 30, 1997, respectively, as compared to $581,000 and
$1,025,000 for the comparable periods in 1996. The primary reason for the
decrease was due to a reduction in Marketing and Sales Management headcount. The
Company believes that marketing and sales expenses will moderately increase
during the remainder of 1997 in connection with the Company's continued efforts
to achieve market acceptance of its products.


<PAGE>   7
General and administrative expenses were $230,000 and $470,000 for the three and
six month periods ended June 30, 1997, respectively compared to $347,000 and
$630,000 for the comparable periods in 1996. The primary reason for the decrease
in expenses was due to a reduction in headcount.

Liquidity and Capital Resources

During the six months ended June 30, 1997, the Company used $1,093,000 of cash
in operations, primarily to fund operating losses. In April 1997, the Company
amended its agreement to raise funds through the issuance of subordinated
convertible debentures. The Company will receive $700,000 in installments during
the remainder of 1997. The Company believes that this cash together with
borrowing from the credit line, which allows it to borrow the lesser of
$1,500,000 or 80% of eligible receivables, and cash generated from operations
will be sufficient to meet its operating requirements at least through the end
of 1997, although the Company anticipates that it will continue to incur net
losses for the foreseeable future. The ability to sustain its operations for a
significant period after December 31, 1997, will depend on the Company's ability
to significantly increase sales or raise significant additional equity or debt
financing. There is no assurance that any of these conditions will be achieved.
In particular, the Company expects to require increasing amounts of cash to
finance the Company's efforts to increase sales, which the Company plans to
achieve by increasing selling efforts to large system integrators and OEMs by
hiring additional sales and sales support staff and by making evaluation units
available. In addition, the Company intends to expand its current network of
resellers. The Company expects that it will require cash to finance purchases of
inventory to satisfy anticipated increased sales as the Company's products
achieve market acceptance.
