                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1. BASIS OF PRESENTATION

The consolidated financial statements of Patriot Scientific Corporation ("the
Company") presented herein have been prepared pursuant to the rules of the
Securities and Exchange Commission for quarterly reports on Form 10-QSB and do
not include all of the information and footnotes required by generally accepted
accounting principles. These statements should be read in conjunction with the
Company's audited financial statements and notes thereto for the year ended May
31, 1998.

In the opinion of management, the interim financial statements reflect all
adjustments of a normal recurring nature necessary for a fair statement of the
results for interim periods. Operating results for the three month and six month
periods are not necessarily indicative of the results that may be expected for
the year.

Income (Loss) Per Share

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Standard of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share," which required the Company to change the method used to calculate
earnings per share. Under SFAS No. 128, basic earnings (loss) per share is
calculated as income (loss) available to common stockholders divided by the
weighted average number of common shares outstanding. Diluted earnings (loss)
per share is calculated as net income (loss) divided by the diluted weighted
average number of common shares. The diluted weighted average number of common
shares is calculated using the treasury stock method for common stock issuable
pursuant to outstanding stock options, common stock warrants, and debt
convertible into common stock. Common stock options of 155,032 and 1,030,686 for
the three months and 180,617 and 1,315,616 for the six months and debt
convertible into none and 2,609,534 common shares of stock for the three months
and 496,089 and 2,173,900 common shares of stock for the six months were not
included in diluted earnings (loss) per share for the periods ended November 30,
1998 or 1997, respectively, as the effect was antidilutive due to the Company
recording losses in each of those periods.

In addition, 4,500,000 shares of common stock in escrow as of November 30, 1998
were not considered outstanding for diluted earnings (loss) per share because
the Company is currently negotiating whether they will be released.

Options and warrants to purchase 4,209,291 shares of common stock at exercise
prices from $0.50 to $2.30 per share were outstanding at November 30, 1998 but
were not included in the computation of diluted earnings (loss) per share
because the exercise prices were greater than the average market price of the
common shares. Options and warrants to purchase 2,039,600 shares of common stock
at exercise prices from $1.37 to $7.50 per share were outstanding at November
30, 1997 but were not included in the computation of diluted earnings (loss) per
share because the exercise prices were greater than the average market price of
the common shares.

Sale of Accounts Receivable

The Company has adopted SFAS No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities" ("SFAS 125"). SFAS 125
provides consistent standards for distinguishing transfers of financial assets
that are sales from transfers that are secured borrowings. Under SFAS 125, after
a transfer of financial assets, an entity recognizes the financial and servicing
assets it controls and the liabilities it has incurred, derecognizes financial
assets when control has been surrended, and derecognizes liabilities when
extinguished. The Company sold approximately $110,000 of its accounts receivable
to a bank under a factoring agreement for approximately $90,000. Pursuant to the
provisions of SFAS 125, the Company reflected the transaction as a sale of
assets and established an accounts receivable from the bank for the retained
amount less the costs of the transaction and less any anticipated future loss in
the value of the retained asset.

Management's Plan

At November 30, 1998, working capital was a negative $643,185 and cash and cash
equivalents totaled $39,355. The Company has funded its operations primarily
through the issuance of securities and debt financings. The Company's liquidity
for the next twelve months is anticipated to be provided by (1) the cash profits
related to the $3.3 million kiosk order, a portion of which is anticipated as an
advance payment previous to any product shipments, (2) short-term debt
instruments, including a receivable financing arrangement established with the
Company's bank, and (3) additional equity financings. At February 15, 1999, the
Company had received a short-term debt financing for $50,000, private equity
placements to a group of individual investors for an accumulated $165,500, and a
commitment for up to $5,000,000 under an equity line of credit. The equity line
of credit allows the Company, at its sole discretion, to put common stock into
the hands of an institutional underwriter at a discount from market, ranging
from 15% to 25% depending on the market price of the common stock, subject to
common stock trading volume limitations and registration of the securities.

With the exception of the financings and commitment discussed above, there can
be no assurance that any funds required during the next twelve months or
thereafter can be generated from operations or that if such required funds are
not internally generated that funds will be available from external sources such
as debt or equity financings or other potential sources. The lack of additional
capital could force the Company to substantially curtail or cease operations and
would therefore have a material adverse effect on the Company's business.
Further there can be no assurance that any such required funds, if available,
will be available on attractive terms or that they will not have a significantly
dilutive effect on existing shareholders of the Company.

2. NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income"
which establishes standards for reporting and display of comprehensive income,
its components and accumulated balances. Comprehensive income is defined to
include all changes in equity except those resulting from investments by owners
and distributions to owners. Among other disclosures, SFAS 130 requires that all
items that are required to be recognized under current accounting standards as
components of comprehensive income be reported in a financial statement that
displays with the same prominence as other financial statements. SFAS 130 has
been adopted and there was no effect on the financial statements.

Also, in June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information" which supersedes SFAS No. 14 "Financial
Reporting for Segments of a Business Enterprise." SFAS No. 131 establishes
standards on the way that public companies report financial information about
operating segments in annual financial statements and requires reporting of
selected information about operating segments in interim financial statements
issued to the public. It also establishes standards for disclosure regarding
products and services, geographic areas and major customers. SFAS No. 131
defines operating segments as components of a company about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance. SFAS 131 is effective for financial statements for periods
beginning after December 15, 1997 and requires comparative information for
earlier years to be restated. Because of the recent issuance of the standard,
management has been unable to fully evaluate the impact, if any, the standard
may have on future financial statement disclosures. Results of operations and
financial position, however, will be unaffected by implementation of the
standard.

In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits" which standardizes the disclosure
requirements for pensions and other postretirement benefits and requires
additional information on changes in the benefit obligations and fair values of
plan assets that will facilitate financial analysis. SFAS No. 132 is effective
for years beginning after December 15, 1997 and requires comparative

information for earlier years to be restated, unless such information is not
readily available. Management believes the adoption of this statement will have
no material impact on the Company's financial statements.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" which requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
market value. Gains or losses resulting from changes in the values of those
derivatives would be accounted for depending on the use of the derivative and
whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. SFAS No. 133 is
effective for fiscal periods beginning after June 15, 1999. Management believes
the adoption of this statement will have no material impact on the Company's
financial statements.

3. INVENTORIES

Inventories are stated at cost ( determined primarily by the weighted average
cost method which approximates cost on a first-in, first-out basis) not in
excess of market value.

Inventories at November 30, 1998 and May 31, 1998, consist of the following:

</TABLE>

A total of 5,000,000 shares of the Company's outstanding common stock was issued
as a contingent cost of the Company's acquisition of its ShBoom Technology. As
of November 30, 1998, 500,000 shares have been released from escrow. At November
30, 1998, 4,500,000 shares remain in escrow of which 3,000,000 shares may have
been earned but remain in escrow pending the resolution of litigation which has
been filed against the Company and nanoTronics, the seller of the ShBoom
Technology, by one of the co-inventors of the technology. Any of the escrowed
shares not released prior to May 31, 1999 are to be returned to the Company and
canceled. The 4,500,000 shares are excluded from the calculation of basic and
diluted weighted average number of common shares outstanding for the computation
of (loss) per share until the shares are released or the dispute is settled.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                   (Unaudited)


At November 30, 1998, the Company had 165,000 options outstanding pursuant to
its 1992 ISO Stock Option Plan exercisable at prices ranging from $0.50 to $2.30
per share expiring beginning 2000 through 2001. The Company had 511,753 options
outstanding pursuant to its 1992 NSO Stock Option Plan exercisable at prices
ranging from $0.18 to $2.30 per share expiring beginning 1999 through 2002. The
Company also had 3,536,691 options outstanding pursuant to its 1996 Stock Option
Plan exercisable at $0.45 to $2.30 per share expiring beginning in 1999 through
2003. Some of the options outstanding under these plans are not presently
exercisable and are subject to meeting vesting criteria.

As of October 1, 1995, the Board of Directors adopted the 1995 Employee Stock
Compensation Plan providing for the issuance of up to 250,000 common shares to
Employees, as defined. Executive officers and directors were not eligible under
the Plan. Through September 30, 1998 the Company had issued 217,600 common
shares pursuant to the plan. The plan expired on September 30, 1998 with no
additional common shares being issued.

At November 30, 1998, the Company has warrants outstanding exercisable into
512,600 common shares at exercise prices ranging from $0.50 to $1.69 per share
expiring beginning in 2000 through 2003.


5. 5% CONVERTIBLE TERM DEBENTURES

In June, 1997, the Company issued to a limited number of investors for cash an
aggregate of $2,000,000 of unsecured 5% Convertible Term Debentures due June 2,
1999 ("Debentures") and Stock Purchase Warrants ("Warrants") with a right to
purchase an aggregate 611,733 shares of common stock, par value $.00001 per
share, at an exercise price of

$1.69125. In September 1998, the exercise price for related warrants to purchase
370,000 shares of common stock was reduced from $1.69125 to $0.36. In November
1997, the Company issued to the same investors for cash an aggregate of
$1,000,000 of Debentures due June 2, 1999 and Warrants with a right to purchase
an aggregate 305,867 shares of common stock, par value $.00001 per share, at an
exercise price of $1.50. In September 1998, the exercise price for related
warrants to purchase 185,000 shares of common stock was reduced from $1.50 to
$0.36. The additional warrants value due to the reduction in the exercise price
of $142,500 was reflected as additional interest expense in the second fiscal
quarter of 1999.

The principal and interest amount of each Debenture could, at the election of
the holder, be converted in whole or in part and from time to time into fully
paid and nonassessable shares of common stock, $.00001 par value, of the
Company, at a price which was the lower of (i) $1.1646 per share or (ii)
depending on the number of days the Debentures had been held after the funding
date, from 75% to 91% of the average of the closing bid prices for the common
stock for the ten consecutive trading days ending on the trading day immediately
preceding such conversion date.

As of November 30, 1998, the Debentures had been fully converted into 6,069,345
common shares of the Company. In addition, as of November 30, 1998, the
investors had exercised warrants to purchase 555,000 common shares of the
Company.

Convertible debt instruments which are convertible at a discount to market were
accounted for by treating such discount as additional interest expense. The
Company computed the amount of the discount based on the difference between the
conversion price and fair value of the underlying common stock on the dates the
Debentures were issued. The Company recorded $2,160,941 of additional paid-in
capital for the discount related to the embedded interest in the Debentures. Of
this amount, $142,830 has been expensed during the six months ended November 30,
1998 under the caption "Non-cash interest expense related to convertible notes."

6. CONTINGENCY

In October 1998 the Company was sued in the District Court for Travis County,
Texas by the Fish Family Trust, a co-inventor of the original ShBoom technology.
The suit also named as defendants nanoTronics and Gloria Felcyn on behalf of the
Falk Trust. The suit sought a judgment for damages, a rescission of the
Technology Transfer Agreement and a restoration of the technology to the
co-inventor. The Company had the suit removed to the United States District
Court for the Western District of Texas, Austin Division, and requested the
Federal District Court to dismiss the suit based on lack of minimum contacts
with Texas or, in the alternative, to transfer the case to the Southern District
of California. In January 1999 the Federal District Court dismissed the suit for
lack of subject matter and personal jurisdiction. The Fish Family Trust then
refiled the suit in the Superior Court of San Diego County, California seeking
remedies similar to the Federal District Court dismissed action.

The Company obtained its rights to the basic ShBoom technology in 1994 pursuant
to an Assets Purchase Agreement and Plan of Reorganization between the Company,
nanoTronics Corporation and Helmut Falk. The basic ShBoom technology was
purchased by nanoTronics from the Fish Family Trust in 1991 pursuant to a Stock
Purchase and Technology Transfer Agreement.

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

THE FOLLOWING DISCUSSION INCLUDES FORWARD-LOOKING STATEMENTS WITH RESPECT TO THE
COMPANY'S FUTURE FINANCIAL PERFORMANCE. ACTUAL RESULTS MAY DIFFER MATERIALLY
FROM THOSE CURRENTLY ANTICIPATED AND FROM HISTORICAL RESULTS DEPENDING UPON A
VARIETY OF FACTORS, INCLUDING THOSE DESCRIBED BELOW UNDER THE SUB-HEADING,
"FUTURE PERFORMANCE AND RISK FACTORS." SEE ALSO THE COMPANY'S ANNUAL REPORT ON
FORM 10-KSB FOR THE YEAR ENDED MAY 31, 1998.

The Company's results of operations have and may continue to be subject to
significant quarterly variation. The results for a particular quarter may vary
due to a number of factors, including the overall state of the microprocessor
and communications segments of the economy, the development status and demand
for the Company's products, economic conditions in the Company's markets, the
timing of orders, the timing of expenditures in anticipation of future sales,
the mix of products sold by the Company, the introduction of new products and
product enhancements by the Company or its competitors and pricing and other
competitive conditions.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED NOVEMBER 30, 1998 AND 1997

Net sales. Total net sales for the second quarter of fiscal 1999 decreased 43.5%
to $230,905 from $408,856 for the second quarter of fiscal 1998. This decrease
was due primarily to rescheduling the product delivery on the Company's $3.3
million kiosk application order coupled with a reduction in follow on shipments
for the Company's matured communication products several of which are
approaching the end of their life cycles. Development and sales of new
communications products have not achieved a level to replace the maturing
products. The balance of the kiosk order is scheduled to be shipped during the
remainder of fiscal year 1999.

Cost of sales. Cost of sales as a percentage of net sales increased to 82.5% for
the second quarter of fiscal 1999 compared to 44.9% for the corresponding
quarter of the previous fiscal year. This increase is due in part to lower
profit margins on the Company's $3.3 million kiosk application order compared to
profit margins typically associated with the Company's other product lines. The
remainder of the kiosk order, which is scheduled to be shipped during the
balance of fiscal year 1999, is anticipated to put upward pressure on the cost
of sales as a percentage of net sales for the current fiscal year when compared
to corresponding periods of the previous fiscal year. In addition, the fixed
production costs being allocated over a reduced sales base during the second
quarter of fiscal 1999 resulted in additional upward pressure on the cost of
sales as a percentage of sales.

Research and development expenses remained substantially the same at $453,497
for the second fiscal quarter of 1999 compared to $452,489 for the second fiscal
quarter of 1998.

Selling, general and administrative expenses decreased by 27.5% from $710,246
for the second quarter of fiscal 1998 to $514,904 for the second quarter of
fiscal 1999. This decrease was due primarily to a $375,000 reduction in costs
related to the release from escrow of 500,000 shares to the seller of the ShBoom
technology during the second quarter of fiscal 1998 offset by an increase in
legal fees during the second quarter of fiscal 1999. When and if the additional
4,500,000 escrowed shares are released, selling, general and administrative
expenses would be impacted significantly.

Other income (expense) was significantly lower for the second quarter of fiscal
1999 as a result of the non-cash interest related to discounted notes discussed
in Note 5 to the consolidated financial statements and the interest on the same
notes.

RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED NOVEMBER 30, 1998 AND 1997

Net sales. Total net sales for the six months ended November 30, 1998 decreased
5.7% to $836,497 from $887,020 for the corresponding period of fiscal 1998. This
decrease was due primarily to rescheduling the product delivery on the Company's
$3.3 million kiosk application order coupled with a reduction in follow on
shipments for the Company's matured communication products several of which are
approaching the end of their life cycles. 


                                       11
<PAGE>   12
Development and sales of new communications products have not achieved a level
to replace the maturing products. The balance of the kiosk order is scheduled to
be shipped during the remainder of fiscal year 1999.

Cost of sales. Cost of sales as a percentage of net sales increased to 68.1% for
the six months ended November 30, 1998 compared to 49.2% for the corresponding
period of the previous fiscal year. This increase is due in part to lower profit
margins on the Company's $3.3 million kiosk application order compared to profit
margins typically associated with the Company's other product lines. The
remainder of the kiosk order, which is scheduled to be shipped during the
balance of fiscal year 1999, is anticipated to put upward pressure on the cost
of sales as a percentage of net sales for the current fiscal year when compared
to corresponding periods of the previous fiscal year.

Research and development expenses increased 40.1% for the six months ended
November 30, 1998 to $1,155,489 from $824,761 for the corresponding period for
the previous fiscal year. This was due to an increase in licensed software
support and update fees for the Java OS and Personal Java application, increased
costs of porting a real time operating system to the PSC1000, and costs related
to the development of the kiosk.

Selling, general and administrative expenses decreased by 32.6% from $1,361,865
for the six months ended November 30, 1998 compared to $917,675 for the
corresponding period of the previous fiscal year. This decrease was due
primarily to a reduction in costs related to the release from escrow of 500,000
shares to the seller of the ShBoom technology during the second quarter of
fiscal 1998 discussed above coupled with a reduction in compensation expenses.

Other income (expense) was significantly lower for the six months ended November
30, 1998 compared to the corresponding period for the previous fiscal year as a
result of the non-cash interest related to discounted notes discussed in Note 5
to the consolidated financial statements and the interest on the same notes.

LIQUIDITY AND CAPITAL RESOURCES

At November 30, 1998, working capital was a negative $643,185 and cash and cash
equivalents totaled $39,355. The Company has funded its operations primarily
through the issuance of securities and debt financings. Cash and cash
equivalents decreased $563,101 during the six months ended November 30, 1998.
The net cash used in operating activities was $689,278, additions to property
and equipment were $273,096, and funds generated from debt and equity financings
were $399,273. During the six months ended November 30 1998, accounts receivable
decreased $223,724 as a result of a reduction in sales and increased collection
efforts. Prepaid expenses increased $166, 098 as a result of maintenance
contracts on software being amortized over the entire year. Accounts payable
increased $828,980 as a result of annual obligations for software maintenance
and a slow down in payments as a result of the cash and cash equivalent
reduction. The Company did procure several short term notes and established an
accounts receivable line of credit with its bank during the second fiscal
quarter of 1999 totaling $194,410.

The Company's liquidity for the next twelve months is anticipated to be provided
by (1) the cash profits related to the $3.3 million kiosk order, a portion of
which is anticipated as an advance payment previous to any product shipments,
(2) short-term debt instruments, including a receivable financing arrangement
established with the Company's bank, and (3) additional equity financings.

The Company anticipates that it may require additional equipment, fabrication,
components and supplies during the next twelve months to continue development of
the Company's technologies. Product introductions such as those currently
underway for communication products and the PSC1000 may require significant
inventory, product launch, marketing personnel and other expenditures not
presently estimable by management. Further, if expanded development is commenced
or new generations of microprocessors or radar are accelerated beyond current
plans, additional expenditures, not currently estimable by management, may be
required. It is possible therefore, that higher levels of expenditures may be
required than currently contemplated by management resulting from changes in
development plans or as required to support new developments or
commercialization activities or otherwise.

Based on the current fiscal year's rate of cash operating expenditures and
current plans, management anticipates additional cash requirements for the next
twelve months. There can be no assurance that any funds required during the next
twelve months or thereafter can be generated from operations or that if such
required funds are not internally generated that funds will be available from
external sources such as debt or equity financings or other potential 


                                       12
<PAGE>   13
sources. The lack of additional capital could force the Company to substantially
curtail or cease operations and would therefore have a material adverse effect
on the Company's business. Further there can be no assurance that any such
required funds, if available, will be available on attractive terms or that they
will not have a significantly dilutive effect on existing shareholders of the
Company.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 131, "Disclosures about Segments
of an Enterprise and Related Information" which supersedes SFAS No. 14
"Financial Reporting for Segments of a Business Enterprise." SFAS No. 131
establishes standards on the way that public companies report financial
information about operating segments in annual financial statements and requires
reporting of selected information about operating segments in interim financial
statements issued to the public. It also establishes standards for disclosure
regarding products and services, geographic areas and major customers. SFAS No.
131 defines operating segments as components of a company about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance. SFAS 131 is effective for financial statements for periods
beginning after December 15, 1997 and requires comparative information for
earlier years to be restated. Because of the recent issuance of the standard,
management has been unable to fully evaluate the impact, if any, the standard
may have on future financial statement disclosures. Results of operations and
financial position, however, will be unaffected by implementation of the
standard.

In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits" which standardizes the disclosure
requirements for pensions and other postretirement benefits and requires
additional information on changes in the benefit obligations and fair values of
plan assets that will facilitate financial analysis. SFAS No. 132 is effective
for years beginning after December 15, 1997 and requires comparative information
for earlier years to be restated, unless such information is not readily
available. Management believes the adoption of this statement will have no
material impact on the Company's financial statements.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" which requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
market value. Gains or losses resulting from changes in the values of those
derivatives would be accounted for depending on the use of the derivative and
whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. SFAS No. 133 is
effective for fiscal periods beginning after June 15, 1999. Management believes
the adoption of this statement will have no material impact on the Company's
financial statements.

YEAR 2000 COMPLIANCE

Many existing computer programs use only two digits to identify a year in the
date field, with the result that data referring to the year 2000 and subsequent
years may be misinterpreted by these programs. If present in the computer
applications of the company or third parties (such as customers, financial
institutions, and suppliers) and not corrected, this problem may cause computer
applications to fail or to create erroneous results and could cause a disruption
in operations and have an adverse effect on the company's business and results
of operations.

The Company adopted a formal plan to evaluate its readiness for the Year 2000
and address any deficiencies. The plan encompasses 1) information technology
(IT) systems, 2) non-IT systems, 3) Company products, and 4) systems of third
parties, including distributors and key suppliers.

         INFORMATION TECHNOLOGY: The Company's principal computer systems that
it uses for financial accounting, manufacturing, inventory control, purchasing,
sales administration, engineering, and other business functions have been
determined to not be Year 2000 compliant. The Company has identified a
replacement system that it will purchase, install, and have fully functional
before June 30, 1999. The cost of this new system will be approximately $30,000.


                                       13
<PAGE>   14
         NON-IT SYSTEMS: By the end of the second quarter of 1999, the Company
expects to have completed an evaluation of telephone systems, manufacturing
equipment, facility heating and cooling systems, and other non-IT systems for
Year 2000 readiness, and will promptly take remedial action as necessary.

         COMPANY PRODUCTS: The Company has completed a series of tests,
utilizing industry standards, of the electronics systems of its products,
including those product lines no longer being manufactured but remaining in use
at customer sites, and has determined that the products should continue to
operate according to specification after December 31, 1999.

         KEY VENDORS AND SUPPLIERS: The Company will initiate a survey of its
key vendors and suppliers to assess their plans for bringing any non-compliant
systems into Year 2000 compliance. Such study is expected to be completed by the
end of the second calendar quarter of 1999.

Other than the replacement computer system discussed above, substantially all of
the effort to evaluate the Company's Year 2000 readiness has been made using
internal personnel, and therefore incremental expenses have been less than
$50,000. The Company has not incurred any material expenses in connection with
its evaluation of non-IT systems, and does not expect material expense in the
future, although the evaluation of non-IT systems is not yet complete. The
Company has not incurred any material expenses to date in connection with the
evaluation of its products and the status of its vendors and suppliers with
respect to Year 2000 issues, and does not anticipate material expenses in the
future, although the evaluation of key vendors' and suppliers' Year 2000
readiness is not yet complete.

Efforts on the Company's Year 2000 readiness plan, as well as its consideration
of contingency plans, are ongoing and will continue to evolve as new information
becomes available. At this stage of the process, the Company believes that it is
difficult to identify the cause of the most reasonably likely worst case Year
2000 scenario. The Company has not yet adopted any formal contingency plans, and
will determine the need for such plans as part of its ongoing assessment of
vendors and suppliers, products, and internal business systems. Due to the
complexity and pervasiveness of the Year 200 issue, and in particular the
uncertainty regarding the Year 2000 compliance programs of third parties, no
assurances can be given that there will not be material adverse effects on the
Company's business or its results from operations.


FUTURE PERFORMANCE AND RISK FACTORS

THIS REPORT CONTAINS A NUMBER OF FORWARD-LOOKING STATEMENTS WHICH REFLECTS THE
COMPANY'S CURRENT VIEWS WITH RESPECT TO FUTURE EVENTS AND FINANCIAL PERFORMANCE.
THE COMPANY'S FUTURE BUSINESS, OPERATING RESULTS AND FINANCIAL CONDITION ARE
SUBJECT TO VARIOUS RISKS AND UNCERTAINTIES, INCLUDING THOSE SUMMARIZED BELOW.
READERS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE ON FORWARD-LOOKING STATEMENTS
CONTAINED HEREIN, WHICH SPEAK ONLY AS OF THE DATE HEREOF. THE COMPANY UNDERTAKES
NO OBLIGATION TO PUBLICLY REVISE THESE FORWARD-LOOKING STATEMENTS, TO REFLECT
EVENTS OR CIRCUMSTANCES THAT MAY ARISE AFTER THE DATE OF THIS REPORT.

Since the business combination with Metacomp, effective December, 1996, the
Company has segregated its operations into microprocessor, communication, and
radar/antenna segments. However, synergistic technical and other resources can
and will be deployed across all three segments.

Product revenues have been primarily from the communication segment. The
communication products are specifically designed to fill both the high speed
data as well as the video conferencing requirements of the Internet.

The microprocessor continues to be the Company's primary development focus. The
Company has completed development of a 0.35 micron version of the PSC1000 which
has resulted in increased processing speed and performance. In addition, the
Company is running the Sun Microsystems's Java OS on the PSC1000. The PSC1000
executes Java very efficiently, and is the price/performance leader in the Java
processor marketplace. This enhancement is expected to increase potential market
opportunities in areas such as TV set top boxes, smart phones, PDAs, network
computers, and other Internet related products.


                                       14
<PAGE>   15
The Company's primary focus for the radar and antenna technology segment
continues to be to pursue various government agencies and commercial entities to
fund additional development efforts and to establish business partnerships that
will enable the Company to commercialize this technology. The Company recently
completed the first phase of a development contract and has submitted a proposal
for additional funding to the Navy to continue development of the gas antenna.

The Company is focusing its sales efforts on original equipment manufacturers,
system integrators, and Internet service providers for both the microprocessor
and communication segments. In addition, the Company anticipates using the
microprocessor in existing and future products developed in all three product
segments.

The Company has experienced in the past and may experience in the future many of
the problems, delays and expenses encountered by any business in the early
stages of development, some of which are beyond the Company's control. The
Company has a limited operating history, has incurred significant cumulated
losses, has only recently commenced marketing and sales of its products and has
not achieved a profitable level of operations. There can be no assurance of
future profitability. The Company may require additional funds in the future for
operations or to exploit its technologies. There can be no assurance that any
funds required during the next twelve months or thereafter can be generated from
operations or that such required funds will be available from the aforementioned
or other potential sources. The lack of additional capital could force the
Company to substantially curtail or cease operations and could therefore have a
material adverse effect on the Company's business. Further there can be no
assurance that any such required funds, if available, will be available on
attractive terms or that they will not have a significantly dilutive effect on
existing shareholders of the Company. The Company's technologies are in various
stages of development. The Company's communication products have been developed
to the point of production of marketable product and the PSC1000 is in the first
stages of production. There can be no assurance that any of the technologies in
development can be completed to commercial exploitation due to the inherent
risks of new technology development, limitations on financing, competition,
obsolescence, loss of key technical personnel and other factors. The Company's
development projects are high risk in nature, where unanticipated technical
obstacles can arise at any time and result in lengthy and costly delays or
result in determination that further development is unfeasible. There can be no
assurance that the technologies, if completed, will achieve market acceptance
sufficient to sustain the Company or achieve profitable operations.

The Company relies primarily on patents to protect its intellectual property
rights. There can be no assurance that patents held by the Company will not be
challenged and invalidated, that patents will issue from any of the Company's
pending applications or that any claims allowed from existing or pending patents
will be sufficient in scope or strength or be issued in all countries where the
Company's products can be sold to provide meaningful protection or commercial
advantage to the Company. Competitors may also be able to design around the
Company's patents.

The Company acquired its ShBoom technology pursuant to a chain of agreements,
and there is uncertainty regarding royalty payments, if any, and indemnification
from prior parties. The Company does not believe it is obligated to pay any
royalties on aspects of the ShBoom technology specified in prior agreements
between nanoTronics Corporation and previous inventors. The Company believes,
should there be royalties due to previous inventors, that the obligation is that
of nanoTronics. The Company could become subject to unindemnified claims
relating to any failure by nanoTronics to pay such royalties, if due. Also the
Company could become liable for up to $1,250,000 to nanoTronics under certain
indemnification provisions. The Company has recently been named as a defendant
in a law suit filed by one of the previous inventors. The Company is unable at
this time to determine the eventual outcome of this suit. The Company's
Consolidated Financial Statements do not include any adjustments that might
result from the outcome of this uncertainty. See "Legal Proceedings."

The Company's common shares are traded on the OTC Bulletin Board, are thinly
traded and are subject to special regulations imposed on "penny stocks." The
Company's shares may experience significant price and volume volatility,
increasing the risk of ownership to investors.
