                         PATRIOT SCIENTIFIC CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

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 l0-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, 1997 and the Company's Form 8Ks dated June 16, 1997 and February 27, 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 nine
month periods are not necessarily indicative of the results that may be expected
for the year.

As a result of the business combination discussed below, the Company no longer
qualifies as a development stage company. Accordingly, the consolidated
statements of operations and statements of cash flows do not include development
stage cumulative results.

Income (Loss) Per Share

Through November 30, 1997, the Company followed the provisions of Accounting
Principles Board Opinion ("APB") 15, "Earnings Per Share." Effective for the
quarter ended February 28, 1998, the Company implemented SFAS No. 128, "Earnings
per Share." SFAS No. 128 provides for the calculation of "Basic" and "Diluted"
earnings per share. Basic earnings per share includes no dilution and is
computed by dividing income available to common stockholders by the weighted
average number of common shares outstanding for the period. Diluted earnings per
share reflects the potential dilution of securities that could share in the
earnings of an entity, similar to fully diluted earnings per share. In loss
periods, dilutive common equivalent shares are excluded as the effect would be
antidilutive. For the three an nine month periods ended February 28, 1998 and
1997, 1,458,570, 1,440,632, 1,458,570 and 1,440,632 dilutive common equivalent
shares of common stock were not included in the computation of diluted earnings
per share because their effect was antidilutive. All prior period earnings per
share data has been restated to reflect the requirements of SFAS No.128.

Restatement

On April 7, 1998, the Company filed its original Form 10-QSB for the third
quarter ended February 28, 1998 in which it recorded non-cash interest expense
related to convertible debt and associated debenture costs. Upon further review,
the Company believes that the amounts recorded were understated and,
accordingly, is filing this amended Form 10-QSB to reflect the additional
charges. As a result of this amendment, the net loss for the three and nine
month period was increased by $1,000,000 or $.04 per share- basic and diluted.
Additional paid in capital was likewise increased by $1,000,000.

2. NEW ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board has issued SFAS No.130, "Reporting
Comprehensive Income" and SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No.130 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 owner and distributions to owners.
Among other disclosures, SFAS No.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 No. 131



                                       6
<PAGE>   7

                         PATRIOT SCIENTIFIC CORPORATION
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                   (Unaudited)

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 al 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 assessing performance.

SFAS 130 and 131 are 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 alter 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.

3. ACQUISITION OF METACOMP, INC. COMMON STOCK

On December 26, 1996, the Company acquired 96.9% of the common stock of Metacomp
in exchange for 1,272,068 shares of the Company's common stock. Metacomp
designs, manufactures, and sells a wide range of high performance data and
telecommunications solutions for wide area networking and digital
telecommunications requirements. The business combination was accounted for as a
pooling of interests. Accordingly, the Company's financial statements have been
restated to include the results of Metacomp for all periods presented.
Metacomp's fiscal yearend has been changed from July 31 to May 31 to conform to
the Company's fiscal yearend. Based on the difference in fiscal year ends,
results of operations for the two months ended July 31, 1996 have been included
in the consolidated statements of operations for the nine months ended February
28, 1997. For the two months ended July 31, 1996, Metacomp recorded total
revenues of $239,501, a net loss before extraordinary item of $37,758,
extraordinary income of $1,779,457 and net income after extraordinary items of
$1,741,699. The accompanying consolidated statement of cash flows has been
adjusted to eliminate the net income after extraordinary items for the nine
months ended February 28, 1997.

4. 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.

5. PURCHASED TECHNOLOGY

Effective May 31, 1994, the Company acquired certain proprietary semiconductor
microprocessor technology (the "ShBoom Chip") and related computer software from
a corporation in exchange for 10,000,000 restricted shares of the Company's
common stock (5,000,000 of which were placed in escrow subject to release as
discussed below). The original cost of this technology, $1,837,000, was based
upon the estimated fair market value of the 5,000,000 non-contingent shares of
the Company's common stock issued under the agreement. The remaining 5,000,000
shares issued for this technology are subject to an earnout escrow arrangement.
As such, when the escrowed shares are earned, they are charged to compensation
in a manner similar to a variable stock option plan. The terms of the escrow
arrangement provide for the release from escrow of 500,000 shares for each
$500,000 of revenues earned by the Company during the period from June 1, 1994
through May 31, 1999. Additionally, this agreement also provides for the release
of these shares upon the occurrence of certain defined major corporate events.
Any of the contingent shares not released by May 31, 1999 would be returned to
the Company and canceled.

During the nine months ended February 28, 1998, 500,000 shares were released
from escrow and $375,000 was charged to compensation costs.

Purchased technology at a cost of $1,837,000 relating to the Company's ShBoom
Technology was amortized over its estimated useful life of three years.
Amortization expense of $163,136 and $489,455 was recorded related to this
technology for the three months and nine months ended February 28, 1997,
respectively.

                                   (Unaudited)

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.
During the nine months ended February 28, 1998, 500,000 shares were released
from escrow and 4,500,000 shares remain subject to an escrow arrangement. The
escrowed shares are releasable from escrow at the rate of 500,000 shares for
each $500,000 of revenues earned by the Company and upon the occurrence of
certain defined major corporate events. These shares are issued and outstanding
and carry all shareholder rights. 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 weighted average number of common
shares outstanding for the computation of loss per share until the release
conditions are met.

At February 28, 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 1998 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 1998 through 2002. The
Company also had 3,471,817 options outstanding pursuant to its 1996 Stock Option
Plan exercisable at $0.18 to $2.30 per share expiring beginning in 1999 through
2002. Some of the options described in this paragraph 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 are not eligible under
the Plan. through February 28, 1998 the Company had issued 217,600 common shares
pursuant to the plan.

At February 28, 1998 the Company had warrants outstanding exercisable into
1,047,600 common shares at exercise prices ranging from $1.50 to $7.50 per share
expiring beginning in 1999 through 2002.

7. 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 and 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 $.0000 1 per share, at an exercise price of
$1.50. The principal and interest amount of each Debenture may, 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 is the lower of (i) $1.1646 per share or (ii)
depending on the number of days the Debentures have 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. If the Debentures have not been converted into
common shares of the Company by June 2, 1999, under certain conditions the
Debentures will automatically be converted into shares of the common stock of
the Company.

As of February 28, 1998, $1,450,000 of the Debentures and the accrued interest
thereon, $48,566, had been converted into 2,896,671 common shares of the
Company.

Convertible debt instruments which are convertible at a discount to market are
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 additional paid-in capital of $1,224,678 for the
discount related to the embedded interest in the Debentures and $400,000 for the
value of the associated warrants. Of this amount, $1,000,000 was expensed during
the three months and $1,624,678 was expensed during the nine months ended
February 28, 1998 and such amounts are included in the statement of operations
under the caption "Non-cash interest expense related to convertible debentures
and warrants."

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, 1997.

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 FEBRUARY 28, 1998 AND 1997

Net sales. Total net sales for the third quarter of fiscal 1998 decreased 47.7%
to $253,691 from $485,199 for the third quarter of fiscal 1997. This decrease
was due to a reduction in the shipment of the Company's older communication
products as a result of anticipated orders slipping into the next fiscal
quarter. Favorable bookings, in excess of $500,000 for the month of March, 1998,
should enable a return to previous year fiscal period levels. Net sales for the
current fiscal period were derived from shipments of the Company's
communication, microprocessor and radar/antenna product lines.

Cost of sales. Cost of sales as a percentage of net sales was 43.1% for the
third quarter of fiscal 1998 compared to 58.7% for the corresponding quarter of
the previous fiscal year. This reduction in the cost of sales percentage was due
to royalties and research billings, revenue items with little or no associated
cost of sales, having a favorable impact on the cost of sales percentage for the
current fiscal period.

Research and development expenses increased by 62.6% from $292,174 for the third
fiscal quarter of 1997 to $475,214 for the third fiscal quarter of 1998. This
increase was due to an increase in licensed software support and update fees and
development and fabrication expenses on the microprocessor.

Selling, general and administrative expenses decreased slightly from $397,923
for the third quarter of fiscal 1997 to $389,043 for the third quarter of fiscal
1998.

Amortization of purchased ShBoom technology, was $163,136 for the third fiscal
quarter of 1997. The technology was totally amortized during fiscal year 1997
and, accordingly, there was no corresponding expense for the third quarter of
fiscal year 1998.

Other income (expense) was significantly higher for the third quarter of fiscal
1998 as a result of the non-cash interest related to discounted notes and
warrants discussed in Note 7 to the consolidated financial statements.

RESULTS OF OPERATIONS FOR THE NINE MONTHS ENDED FEBRUARY 28, 1998 AND 1997

Net sales. Total net sales for the first nine months of fiscal 1998 were 17.2%
lower, $1,140,711, compared to the corresponding period of fiscal 1997,
$1,377,228. This reduction in net sales was a result of the slippage in bookings
discussed above. Net sales for the current fiscal period were derived from the
Company's communication, microprocessor and radar/antenna product lines.



                                       11
<PAGE>   12


Cost of sales. Cost of sales as a percentage of net sales was 47.9% for the
first nine months of fiscal 1998 compared to 47.8% for the corresponding period
of fiscal 1997.

Research and development expenses increased by 26.8% from $1,025,235 for the
first nine months of 1997 to $1,299,975 for the first nine months of fiscal
1998. This increase was due to an increase in licensed software support and
update fees.

Selling, general and administrative expenses increased by 64.5% from $1,064,575
for the first nine months of fiscal 1997 to $1,750,908 for the first nine months
of fiscal 1998. This increase was due primarily to the costs related two
financings accumulating $3,000,000, an increase in personnel costs related to
the Company's addition of two executives, one marketing and one financial, the
compensation costs related to the release from escrow of 500,000 shares of
common stock as discussed in Note 4, and the increase in marketing costs related
to introducing the Company's products to the marketplace.

Amortization of purchased ShBoom technology was $489,455 for the first nine
months of fiscal 1997. The technology was totally amortized during fiscal year
1997 and, accordingly, there was no corresponding expense for the comparable
period of fiscal year 1998.

Other income (expense) was significantly higher for the first nine months of
fiscal 1998 as a result of the non-cash interest related to discounted notes and
warrants discussed in Note 7 to the consolidated financial statements.

An extraordinary income item of $1,779,457 was included in the first nine months
of fiscal 1997. This item was the result of the discharge of debts by Metacomp
in July, 1996 as a result of their successful completion of their Chapter 11
case.

LIQUIDITY AND CAPITAL RESOURCES

At February 28, 1998, working capital was $1,822,429 and cash and cash
equivalents totaled $1,196,644. The Company has funded its operations primarily
through the issuance of securities. The cash and cash equivalents increased
$718,969 during the nine months ended February 28, 1998. The net cash used in
operating activities of $2,233,910 and additions to property and equipment of
$285,701 was offset by a new issuance of convertible debt in the amount of
$3,000,000.

The Company's liquidity for the next twelve months is anticipated to be
supplemented by introducing to market and commencing sales and licensing of the
ShBoom, the technology used in the PSC 1000 family of microprocessor computer
chips, designing future generations of communication product technologies,
exploiting the radar and antenna technology and by expanding the marketing of
communication products.

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 PSC1OOO may require significant
inventory, product launch 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 will be met from debt or equity financings, improved product sales
or the sale or licensing of certain of the Company's technologies. 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



                                       12
<PAGE>   13

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.

NEW ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board has issued SFAS No.130, 'Reporting
Comprehensive Income" and SFAS No.131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No.130 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 owner and distributions to owners.
Among other disclosures, SFAS No.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 No.131 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 130 and 131 are 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 1993, 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 begriming 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.

YEAR 2000 COMPLIANCE

The Company, like most owners of computer software, will be required to modify
significant portions of its software that it will function properly in the year
2000. Preliminary estimates of the total costs to be incurred by the Company to
resolve this problem range from $20,000 to $30,000. Since the Company mainly
uses third party "off-the-shelf" software, it does not anticipate a problem in
resolving the 2000 problem in a timely manner. Maintenance or modification costs
will be expensed as incurred, while the costs of new software will be
capitalized and amortized over the software's useful life.

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, 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 is currently shipping a 0.5 micron version of the PSC1000 that has
increased processing speed and performance over an earlier version. The Company
is currently developing a 0.35 micron version of the PSC 1000 which will further
increase the processing speed and performance. Shipments of the 0.35 micron
version are anticipated during the third calendar quarter of 1998. In addition,
the Company is running the Sun Microsystems's Java OS on the PSC1000. The
PSC1000 is expected to execute Java very efficiently, and to be 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.

The Company's primary focus for the radar and antenna technology segment
continues to be 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 has completed
one development contract and has commenced work on a research contract with the
Navy to demonstrate characterization 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 retained the services of an investment bank to assist the
Company in identifying strategic partnerships for the Company's products.

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 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 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. The Company's technologies are in various
stages of development. The Company's CybersharkTM digital modem and certain
communication products have



                                       14
<PAGE>   15

been developed to the point of production of marketable product and the PSC 1000
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 t sustain the Company or achieve profitable operations.

The Company acquired the basic ShBoom technology, from nanoTronics Corporation
in return for 10,000,000 shares of the Company's common stock in 1994. 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 a previous inventor. The Company believes, should there be royalties due to
the previous inventor, that the obligation is that of nanoTronics. The Company
has been informed by nanoTronics that a tender of a part of the consideration
paid by the Company to nanoTronics for the basic ShBoom technology,' has
initially been rejected by the inventor and that the inventor has proposed that
he is entitled to royalties and that the basic technology,' be returned by
nanoTronics and licensed back to the Company. The Company believes the inventors
claims are without merit and frivolous. nanoTronics has rejected this proposal;
and the Company and nanoTronics are continuing discussions with the inventor in
an effort to resolve these issues. However, if it is ultimately determined that
the inventor is entitled to royalties, the Company could be subject to
indemnification claims by nanoTronics of up to $1,250,000 pursuant to its
agreement with nanoTronics.

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'
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'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.
