              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1 - Unaudited interim financial statements:
                 The accompanying unaudited condensed consolidated financial
                 statements have been prepared in accordance with accounting
                 principles generally accepted in the United States of America
                 for interim financial information and with the instructions to
                 Form 10-Q and Article 10 of Regulation S-X. Operating results
                 for the six-month period ended September 30, 2001 are not
                 necessarily indicative of the results that may be expected for
                 the year ending March 31, 2002. The unaudited condensed
                 consolidated financial statements should be read in conjunction
                 with the consolidated financial statements and footnotes
                 thereto included in the Company's annual report on Form 10-K
                 for the year ended March 31, 2001.


Note 2 - Basis of presentation and other matters:
                The unaudited condensed consolidated financial statements
                include the accounts of GreyStone Digital Technology, Inc,
                formerly Express Capital Concepts, Inc. and GreyStone
                Technology, Inc. (the "Company"). All significant inter-company
                accounts and transactions are eliminated in consolidation.

                As shown in the accompanying consolidated financial statements
                at September 30, 2001, the Company had a working capital
                deficiency of $3,738,328 and a stockholders' deficiency of
                $3,359,618, incurred a net loss of $1,077,967, for the three
                months ended September 30, 2001, and an accumulated deficit from
                losses since its inception of $54,398,433. These matters raise
                substantial doubt about the ability of the Company to continue
                as a going concern.

                Historically, the Company has funded deficits from its business
                operations primarily through sales of common stock to and
                borrowings from its principal stockholder and sales of common
                stock and convertible notes payable to private investors
                pursuant to private placement memorandums and exemptions from
                registration under the Securities Act of 1933. Management plans
                to obtain the additional funds needed to enable the Company to
                continue as a going concern through the private placements of
                debt or equity securities. However, management cannot provide
                any assurance that the Company will be successful in
                consummating these private placements.

                The accompanying condensed consolidated financial statements
                have been prepared in conformity with accounting principles
                generally accepted in the United States of America which
                contemplate that the Company will continue as a going concern
                and continue operations, realization of assets and satisfaction
                of liabilities in the ordinary course of business. If the
                Company is unable to raise additional capital, it may be
                required to liquidate assets or take actions that may not be
                favorable to the Company in order to continue its operations.
                The consolidated condensed financial statements do not include
                any adjustments that might result from the outcome of these
                uncertainties.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 3 - Earnings (loss) per share:
                The Company follows the provisions of Statement of Financial
                Accounting Standards No. 128, Earnings per Share, which requires
                the presentation of "basic" and "diluted" earnings (loss) per
                common share, as further explained in Note 1 of the notes to the
                audited financial statements of the Company, included in Form
                10-K for the fiscal year ended March 31, 2001.

                Since the Company had losses applicable to common stock in the
                three and six month periods ended September 30, 2001 and 2000,
                the assumed effects of the exercise of outstanding stock
                options, warrants and convertible preferred stock were
                anti-dilutive and, accordingly, dilutive per share amounts have
                not been presented in the accompanying condensed consolidated
                unaudited statements of operations. Such options, warrants and
                convertible preferred stock could potentially dilute basic
                earnings per share in the future.


Note 4 - Discontinued operations:
                Previously, the Company identified and reported on two industry
                segments based on strategic business units that were in turn
                based along market lines. The Government Business Unit which
                works primarily as a contractor for U.S. defense contractors and
                the U.S. Government, and the Commercial Business Unit which
                developed products to be sold for entertainment centers and home
                entertainment. In June 2001, the Company discontinued its
                Commercial Business Unit and eliminated that business segment.
                Accordingly, the condensed consolidated financial statements
                have been restated to reflect the losses associated with this
                segment as losses from discontinued operations. In addition, the
                Company estimated the additional losses to be incurred from
                discontinued operations until the Unit's operations totally
                cease, and accrued an additional loss for disposing of the
                Commercial Business Unit as of March 31, 2001.


Note 5 - Significant changes in status of litigation:
                On June 29, 2001 a lawsuit was filed against GreyStone and
                Richard A. Smith by Capital Solutions Fund LLC, the lender of
                the Company's February 2001 line of credit, in the Superior
                Court of the State of California, County of San Diego for breach
                of contract and fraud. A total of $1,050,000 (including $205,000
                in loan fees) was drawn on the line of credit before the lender
                called the line. The line was called as a result of the March
                2001 dissolution of GreyStone's exclusive distributor of the
                MercRacer entertainment system by the distributor's parent
                corporation. Both GreyStone and its CEO, Richard Smith,
                vehemently deny the claims and intend to vigorously defend
                against the suit. In August 2001 GreyStone's filed a cross
                complaint against Capital Solutions Fund LLC, for breach of
                contract and fraud. The Superior Court of the State of
                California for the County of San Diego set a Mandatory
                Settlement Conference scheduled for January 23, 2002. See Note
                9, which discusses the subsequent settlement of the suit.

                Additionally, the Company has entered into settlements in five
                other legal actions ranging between $1,441 to $138, 380 , and
                include: one vendor, one previous employee, one temporary
                employment agent, two employee placement firms, and two public
                relations or advertising firms. Settlement negotiations continue
                with three other claimants.

                                   (Unaudited)

Note 6 - Equity transactions:
                From April 1, 2001 through September 30, 2001, 990 shares of
                Series A Preferred Stock issued at a price of approximately
                $990,000 were converted into 6,962,365 shares of common stock.
                Subsequent to September 30, 2001 and through December 12, 2001,
                approximately 554 shares of Series A Preferred Stock issued at a
                price of approximately $554,000 were converted into 1,829,847
                shares of common stock.

                On May 18, 2001 the Board of Directors authorized the issuance
                of warrants to purchase an aggregate of 1,100,000 shares of
                common stock, with exercise prices ranging from $1.00 to $2.50
                per share. The warrants were issued to short-term lenders of
                cash. On May 18, 2001 the Board also authorized the issuance of
                options to purchase 1,830,000 shares of common stock to
                employees under the 2000 Stock Option Plan at an exercise price
                of $0.20 per share. On September 18, 2001, the Company issued
                1,130,000 of the options that had been approved by the Board of
                Directors on May 18, 2001. The balance of the options approved
                by the Board, 700,000, have not been issued through September
                30, 2001.

                In June and July 2001, the Company raised $651,000 through the
                sale of common stock to 11 accredited investors at prices
                ranging from $0.05 to $0.10 per share. The Company issued
                8,537,000 shares of common stock, which included 1,302,000
                shares issued to 2 parties who introduced the investors to the
                Company's private placement. The proceeds were used for general
                corporate purposes.

Note 7   - License Agreement
                On July 16, 2001, the Company entered into a 99 year Marketing
                and License Agreement with Kiboga Systems, Inc., ("Kiboga") a
                privately-held Texas corporation engaged in the business of
                development and sale of technology products for law enforcement,
                defense and intelligence applications. The Company shall serve
                as marketing agent and advisor, with responsibility for securing
                legal and other advice in conjunction with such business
                opportunities, and will assume financial responsibility for all
                such attendant expenses.

                Under the agreement, the Company will pay Kiboga a 20% royalty,
                and receive the remaining 80% of the revenue generated by those
                applications of Kiboga's network data mining, acquisition and
                distribution software. The Company will be entitled to 100% of
                any profits generated by this activity in return for a payment
                by the Company of 29,614,274 shares of common stock
                (subsequently adjusted as described below) and $700,000 in cash.
                The agreement provides that the Company will issue an additional
                1,000,000 to 15,000,000 common shares if the earnings
                contributed to the Company from the Kiboga software are between
                $8,572,727 and $29,572,727 over the next 24 months beginning
                July 16, 2001. If revenues are less than $6,000,000 through the
                next 12 months beginning July 16, 2001 then Kiboga will return
                5,000,000 shares to the Company. In addition, the agreement
                provides for an anti-dilution formula, which effectively ensures
                that the owner of the share's percentage of ownership cannot be
                diluted by future transactions. The agreement anticipates
                changes in management and directors of the Company. The
                transaction was required to be approved by the shareholders,
                which was completed on October 8, 2001. Accordingly, this is the
                effective date of the transaction. On October 15, 2001, the
                Company issued to Kiboga 29,614,274 shares of restricted stock,
                and on January 12, 2002 the Company issued to Kiboga a further
                1,195,705 shares of restricted stock. As of the date of this
                filing, the $700,000 cash payment to Kiboga has not been made.
                The shares issued under the agreement resulted in a change of
                control of the Company. Also see Note 9, Subsequent Events.

Note 8 - Series A Convertible Preferred Stock:
                On May 22, 2000, the Company completed the sale of $5,000,000 in
                convertible preferred stock to a group of private investors. The
                Company issued 5,000 shares of Series A Preferred Stock,
                convertible immediately at the holders' discretion, into common
                stock at a rate of the lower of (1) 250 shares of common stock
                per share of preferred stock (equivalent to an investment of
                $4.00 per share of common stock issued) or (2) 80% of the volume
                weighted average price for the previous 250,000 shares traded
                prior to submission by the preferred stockholder of a conversion
                notice to the Company. Embedded in the preferred stock is a
                mandatory conversion requirement effective three years after the
                date of issuance. The Series A investors also received warrants
                to purchase 1,250,000 shares of common stock at an exercise
                price of $5.38 per share, and registration rights on the
                conversion shares and the shares issuable upon the exercise of
                the warrants. The preferred stock provides for a cumulative
                dividend of 8% per year, payable in common stock or cash. After
                payment of a 10% commission for introducing the investors to the
                Company, and legal fees totaling approximately $50,000, the
                Company received net proceeds of approximately $4,449,000 which
                it used for general corporate purposes. In accordance with the
                Emerging Issues Task Force (EITF) Issue No 98-5, the Company
                recognized a beneficial conversion feature in the amount of
                $804,103 as a one-time non-cash preferred stock dividend. The
                amount represented the difference between the initial conversion
                price at the date of issuance of the preferred shares and the
                market price of the common stock at that date. In addition, the
                Company recorded a one time, imputed (non-cash) preferred stock
                dividend of $3,437,500 as a result of allocating a portion of
                the proceeds received to the fair value of the warrants issued,
                as determined by the Black-Scholes model.

                In connection with the above sale of convertible preferred
                stock, the Company issued warrants to purchase 75,000 shares of
                common stock at an exercise price of $5.38 per share to the
                party who introduced the Company to the Series A private
                placement group. As a result, the Company recorded a one-time
                imputed (non cash) preferred stock dividend of $207,750.

                The aforementioned imputed preferred stock dividends associated
                with issuing the stock resulted in a one-time loss applicable to
                common stockholders of $(0.27) per share. The Company also
                recorded a non-cash preferred stock dividend of $123,106 for the
                six-month period ended September 30, 2001 due to the 8%
                cumulative preferred stock dividend feature.

Note 9 - Subsequent events:
                In October 2001, a majority of the holders of the voting power
                of the common stock of the Company, holding not less than a
                sixty percent majority did adopt by their written consent the
                approval of the Kiboga transaction announced on September 27,
                2001, and did ratify and confirm the issuance of all 29,614,274
                restricted shares to Kiboga under the Agreement;

                In November 2001, the Company signed a Letter of Intent by and
                among Kiboga Systems, Inc. a private company incorporated in the
                State of Texas, and Proyecciones Y Ventas Organizadas, S.A. DE
                C.V., a private company incorporated in the United Mexican
                States, together with its affiliates (collectively PROVO),
                wherein, the parties expressed their intent to further enter
                into a series of transaction agreements (the Agreements)
                involving revenue, profit and equity transfers, and investment
                capital, and furthermore, expressed their intent to jointly
                develop reciprocal relationships in business developing a PROVO
                offering of new products and services for banking and
                international transfers and for non-banking transactions. The
                Company filed FORM 8-K on November 13, 2001 announcing that, in
                conjunction with Kiboga Systems, Inc., that that it entered into
                merger discussions with PROVO.

                In January 2002, the Company issued an additional 1,195,705
                restricted shares to Kiboga under the provisions of the
                marketing and license agreement and thereto, to bring the
                Agreement into compliance.

                In December 2001, a majority of the holders of the voting power
                of the common stock of the Company, holding not less than a
                two-thirds majority did adopt by their written consent the
                approval of the PROVO/Kiboga transactions and directed the BOD
                to take all actions appropriate and necessary to implement the
                Agreements; additionally to spin off all Company government and
                law enforcement operations; to relocate the Company corporate
                offices from San Diego, California to Dallas, Texas; and name a
                board who will advise the Company.

                As of the date of the original filing of this 10Q, the Company
                had no cash and no accounts receivable and current liabilities
                of almost $3,750,000. These obligations include accounts payable
                and accrued expenses of approximately $2,251,000, (of which
                approximately $595,000 are now over 90 days past due),
                short-term notes payable of approximately $1,518,000, including
                $131,000 that is due to the principal stockholder, and
                $1,050,000 for a line of credit that has been called. Salary and
                accrued vacation obligations are approximately $981,000
                including $639,000 of salary that is currently overdue. A third
                Company officer has recently resigned. Overdue salary
                obligations to the remaining officers are equal to the eleven
                most recent (twice monthly) pay periods. Back salary is also
                owed to the three officers who have resigned. Additionally, many
                employees have not been paid for several pay periods prior to
                the filing of this report, and many employee and officer expense
                reports remain unpaid.

                As discussed in Note 5, on June 29, 2001 a lawsuit was filed
                against GreyStone and Richard A. Smith by Capital Solutions Fund
                LLC, the lender of the Company's February 2001 line of credit,
                in the Superior Court of the State of California, County of San
                Diego for breach of contract and fraud. The court set a
                Mandatory Settlement Conference for January 23, 2002, at which
                time the parties agreed and stipulated to settlement, which was
                recited on the record pursuant to California Code of Civil
                Procedure. The Company agreed to repay the sum of $1,220,000
                according to a repayment schedule, which provides for payments
                through September 15, 2002, commencing with a $72,000 payment in
                February 2002. Furthermore, the parties agreed to enter into a
                Stipulation for Entry of Judgment. The Company has not made any
                payment to date and accordingly, Capital Solutions Fund LLC may
                make an ex parte application to the San Diego Superior Court for
                entry of Judgment. Upon receipt of all payments Capital
                Solutions shall dismiss the Action against the Company. Pursuant
                to the settlement entered into on the record on January 23, 2002
                Capital Solutions complaint against Richard A. Smith is
                dismissed with prejudice, and GreyStone's cross-complaint
                against Capital Solutions is dismissed with prejudice.

                Greystone management, based on discussions with Kiboga, has
                agreed to deliver a $700,000 note receivable previously written
                off by the Company to settle in full the $700,000 note due to
                Kiboga under the agreement.

                Management of the company has verbally agreed to extend the
                period under which revenue targets should be met related to the
                5,000,000 shares to be returned to the Company, as described in
                note 7.

MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2001 AND 2000

Revenues for the three-months ended September 30, 2001 were $374,669 as compared
to $655,993 for the three-months ended September 30, 2000, reflecting a decline
in revenue of $281,324 or approximately 43%. The reduction was primarily the
result of a narrowing in scope and early conclusion of two previously awarded
delivery orders by two Navy customers. Support continues two military
experimentation events, follow on tasking from current customers and additional
subcontracting activities in the Government Strategic Business Unit (SBU).
During the current reporting period, the Government SBU completed support to a
major Joint Forces experiment and on additional delivery orders, provided
engineering services work to BMH Associates and the Office of Naval Research,
General Atomics Aeronautical Systems, Titan, Veridian Engineering, the Joint
Strike Fighter Program Office and the San Diego Space and Naval Warfare Systems
Center.

As of September 30,2001, the Company's backlog of awarded work was approximately
$363,000. The entire backlog is expected to be completed in the fiscal year
ended March 31, 2002.

Cost of revenues decreased to $440,782 during the current three-month period, as
compared to $494,414 for the same three-month period in the previous year. As a
percentage of revenues, costs of revenues were approximately 118% in the current
period, compared to 75% in the previous period. Cost of revenues increased in
the current period due to a decline in contractual work as a result of the loss
of two major programs, an increase in purchased engineering services, an
increase in the Government SBU overhead rate and fringe rate, from the rates in
the prior period. The Government SBU overhead rate increase was the result of a
greater level of support of Government SBU overhead activities during the
current three-month period, as well as a decline in the direct charging work
during the current quarter. The fringe rate applied to the cost of revenues for
the current three-month period was greater than the fringe rate for the previous
period due to an overall reduction in company personnel in the current period,
while medical claims did not vary significantly.

The components that make up the cost of revenues include burdened labor, direct
travel, other direct costs, direct material, subcontracts and applicable SBU
burden. These cost components can vary in amount from period to period and are
highly dependent on such factors as the nature of the work performed, location
and duration of the work (company vs. contractor site), who performed the work
(company personnel vs. subcontractors) and who provided any required equipment
(company vs. customer).

Marketing and sales expenses were $227,623 or 61% of revenues in the current
period compared to $191,198 or 29% of revenues for the previous period, an
increase of $36,425 in the current period. The increase in marketing and sales
expenses was primarily the result of a greater level of bid and proposal
activity in the current period. In general, marketing and sales expenses result
from bid and proposal activity as well as attendance at trade shows, Company
product demonstrations and in-house marketing related activities such as product
brochures and marketing software development. These types of expenses vary from
period to period and are highly dependent upon the extent and manner in which
the company focuses its efforts regarding potential future opportunities during
the reporting period.

MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS OF
OPERATIONS FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2001 AND 2000 (cont'd)

Research and development expenses increased to $169,787 for the current period,
compared to $148,512 for the previous period, resulting in an increase of
$21,275. The increase was the result of increased development expenses for RAGE
TM.

General and administrative expenses were $587,554 in the current period,
compared to $946,273 for the previous period, a decrease of $358,719. The
reductions were the result of the Company downsizing its operations, reducing
the number of employees and curtailing expenses for public relations and outside
consulting and professional services fees.

Other income (expense) of $(26,890) consisted of interest income of $146,
interest expense of $(59,594), primarily for a line of credit and miscellaneous
income of $32,558, which included a sale of entertainment equipment for $31,000.
In the previous period, other income was $48,450 and consisted of interest
income, including $1,668 of interest income from related parties' notes.

The loss from continuing operations was $1,077,967 for the current period
compared with $1,075,954 for the previous period. The loss from operations
declined by $ 73,327 in the current period, while other income declined by
$75,340. The loss from discontinued operations for the current period was $0, as
compared to $429,288 for the previous period

The net loss of $1,077,967 decreased by $427,275 from the $1,505,242 net loss
reported in the previous reporting period. In summary, during the current
period, revenues were down by $281,324 during the current period, while the loss
from continuing operations increased by $2,013 and the loss from discontinued
operations declined by $429,288.

The Company recorded a non-cash preferred stock dividend of $56,979 for the
three month period ended September 30, 2001, as compared to $99,726 for the
three month period ended September 30, 2000, for the 8% preferred stock dividend
feature provided for in the Series A Convertible Preferred Stock.

The net loss applicable to common stock was $1,134,946 for the current period.
This compares to $1,604,968 in the previous period.

MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS OF
OPERATIONS FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2001 AND 2000

Revenues for the six-months ended September 30, 2001 were $1,088,926 as compared
to $1,196,037 for the six-months ended September 30, 2000, reflecting a decrease
in revenue of $107,111 or approximately 9%. The reduction was primarily the
result of a narrowing in scope and early conclusion of two previously awarded
delivery orders by two Navy customers, during the second quarter of the year.
The company anticipates that the decline in quarterly revenue will continue into
the next quarter, before increasing in the final quarter of the year.

As of September 30,2001, the Company's backlog of awarded work was approximately
$363,000. The entire backlog is expected to be completed in the fiscal year
ended March 31, 2002.

Cost of revenues decreased to $802,820 during the current six-month period, as
compared to $917,916 for the same six-month period in the previous year. As a
percentage of revenues, costs of revenues were approximately 74% in the current
period, compared to 76% in the previous period. Although the cost of revenues,
as percentage of revenues, has not changed significantly from the previous
reporting period, the current quarterly data shows an increasing percentage
ratio. For the three-months ended June 30, 2001, the cost of revenue to sales
percentage was approximately 51%, while the corresponding period a year earlier
was 78%. However, for the three-month period ended September 30, 2001, the cost
of revenue to sales percentage was approximately 118%, compared to 75% for the
same three-month period in 2000. Because of the decline in the current business
base and other reasons cited in the management discussion and analysis of
financial condition and results of operations for the three months ended
September 30, 2001, this trend is likely to continue into at least the next
quarter and perhaps longer.

The components that make up the cost of revenues include burdened labor, direct
travel, other direct costs, direct material, subcontracts and applicable SBU
burden. These cost components can vary in amount from period to period and are
highly dependent on such factors as the nature of the work performed, location
and duration of the work (company vs. contractor site), who performed the work
(company personnel vs. subcontractors) and who provided any required equipment
(company vs. customer).

Marketing and sales expenses were $418,575 or 38% of revenues in the current
period compared to $446,090 or 37% of revenues for the previous period, a
decrease of $27,515 in the current period. The decrease in marketing and sales
expenses was primarily the result of a lower level of bid and proposal activity
in the current period. In general, marketing and sales expenses result from bid
and proposal activity as well as attendance at trade shows, company product
demonstrations and in-house marketing related activities such as product
brochures and marketing software development. These types of expenses vary from
period to period and are highly dependent upon the extent and manner in which
the company focuses its efforts regarding potential future opportunities during
the reporting period.

Research and development expenses increased to $316,468 for the current
period, compared to $262,265 for the previous period, resulting in an increase
of $54,203. The increase was the result of increased development expenses for
RAGE(TM).

MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2001 AND 2000 (cont'd)

General and administrative expenses were $1,238,862 in the current period,
compared to $1,927,637 for the previous period, resulting in a decrease of
$688,775. Of the $688,775 decline in general and administrative expenses,
$193,514 was a non-cash compensation expense decrease associated with the
issuance of warrants and compensatory stock options. The balance of the decrease
was the result of the company downsizing its operations, reducing the number of
employees and curtailing expenses for public relations and outside consulting
and professional services fees.

Other income (expense) of $(32,064) consisted of interest income of $17,646,
interest expense of $(82,878), primarily for a line of credit and miscellaneous
income of $33,168, which included a sale of entertainment equipment for $31,000
In the previous period, other income was $75,857 and consisted of interest

$107,921. The loss from discontinued operations for the current period was $0,

The net loss of $1,719,863 decreased by $1,221,884 from the $2,941,747 net loss
reported in the previous reporting period. In summary, during the current
period, revenues were down by $107,111 during the current period, while the loss
from continuing operations declined by $562,151 and the loss from discontinued
operations declined by $659,733.

The Company recorded a non-cash preferred stock dividend of $123,106 for the
six-month period ended September 30, 2001, as compared to $143,561 for the
six-month period ended September 30, 2000, for the 8% preferred stock dividend
feature provided for in the Series A Convertible Preferred Stock.

The net loss applicable to common stock was $1,842,969 for the current period.
This compares to $7,534,661 in the previous period. During the previous period,

for the beneficial conversion feature associated with the preferred stock issued
in May 2000.

The net cash used in operating activities was $1,348,791 in the current period,
as compared to $2,640,780 in the previous reporting period.

There was no cash used in investing activities during the current six month
reporting period. In the previous reporting period, net cash used for investing
activities was $659,520. Previous period investing activities included purchases
of software licenses and equipment of $158,864, additions to leasehold
improvements of $45,656 and the June 2000 purchase of finished goods inventory
in the amount of $330,000 from a target company which GreyStone entered into a
letter of intent to acquire. Additionally, in June 2000 the Company gave the
target Company $135,000 for the right to receive future payments on invoices to
be generated by the target company upon the completion of work in progress.
GreyStone has solicited the help of an agent to assist in the sale of the
finished goods inventory, and negotiations are underway regarding the goods'
sale. Due to the uncertainty of collection on the contract receivable and the
sale of the finished goods inventory, reserves of $135,000 and $230,000 have
previously been established for the contract receivable and finished goods
inventory.

Net cash provided by financing activities was $964,821 in the current period, as
compared to $4,449,353 for the previous period. Of the $964,821 of net cash
provided in the current period, $470,921 was from issuances of short-term notes
payable and $651,000 was provided by the sale of common stock from a private
placement. Additionally, $157,100 of cash was used to repay short-term notes
payable. The $4,449,253 of the cash provided for financing activities in the
previous period was the net result of the sale on May 22, 2000 of $5,000,000 in
convertible preferred stock to a group of private investors and is net of a 10%
commission and legal fees. The net proceeds were used by the Company for product
development and general corporate purposes.

At September 30, 2001, the Company had no cash, as compared to $383,970 for the
fiscal year ended March 31, 2001. The Company anticipates that in the future, it
will need to obtain additional debt or equity financing to continue its
operations for at least the next 12 months.

As of the date of this filing, the Company had no cash, no outstanding accounts
receivable, and current liabilities of almost $4,000,000. These obligations
include accounts payable and accrued expenses of approximately $1,100,000 (of
which approximately $728,000 are now over 90 days past due), and short-term
notes payable of approximately $1,738,000 including approximately $250,000 that
is due to the principal stockholder, and $1,050,000 for a line of credit that
has been called. Salary and accrued vacation obligations are approximately
$1,213,000 including approximately $932,000 of salary that is currently overdue.
Overdue salary obligations to the officers are approximately equal to the eleven
most recent (twice monthly) pay periods. Back salary is also owed to resigned
officers. Additionally, many employees have not been paid for several pay
periods prior to the filing of this report, and many employee and officer
expense reports remain unpaid.

PART II.  OTHER INFORMATION

ITEM 1.   LEGAL PROCEEDINGS
                On June 29, 2001 a lawsuit was filed against GreyStone and
                Richard A. Smith by Capital Solutions Fund LLC, the lender of
                the Company's February 2001 line of credit, in the Superior
                Court of the State of California, County of San Diego for breach
                of contract and fraud. A total of $1,050,000 (including $205,000
                in loan fees) was drawn on the line of credit before the lender
                called the line. The line was called as a result of the March
                2001 dissolution of GreyStone's exclusive distributor of the
                MercRacer entertainment system by the distributor's parent
                corporation. Both GreyStone and its CEO, Richard Smith,
                vehemently deny the claims and intend to vigorously defend
                against the suit. In August 2001 GreyStone's filed a cross
                complaint against Capital Solutions Fund LLC, for breach of
                contract and fraud. The Superior Court of the State of
                California for the County of San Diego set a Mandatory
                Settlement Conference scheduled for January 23, 2002. The
                parties participated in the Settlement conference on January 23,
                2002, at which time the parties agreed and stipulated to
                settlement, which was recited on the record pursuant to
                California Code of Civil Procedure. The Company agreed to repay
                the sum of $1,220,000 according to a repayment schedule
                culminating September 15, 2002. Furthermore, the parties agreed
                to enter into a Stipulation for Entry of Judgment. In the event
                that the Company fails to make any payment in the manner agreed,
                Capital Solutions Fund LLC may make an ex parte application to
                the San Diego Superior Court for entry of Judgment. Upon receipt
                of all payments Capital Solutions shall dismiss the Action
                against the Company. Pursuant to the settlement entered into on
                the record on January 23, 2002 Capital Solutions complaint
                against Richard A. Smith is dismissed with prejudice, and
                GreyStone's cross-complaint against Capital Solutions is
                dismissed with prejudice.

                Additionally, the Company has entered into settlements in five
                other legal actions ranging between $1,441 to $138, 380, and
                include: one vendor, one previous employee, one temporary
                employment agent, two employee placement firms, and two public
                relations or advertising firms. Settlement negotiations continue
                with three other claimants.
