                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1 - Unaudited interim financial statements:
                In the opinion of management, the accompanying unaudited
                financial statements reflect all adjustments, consisting of
                normal recurring accruals, necessary to present fairly the
                financial position of the accounts of GreyStone Digital
                Technology, Inc. (the Parent) and its subsidiary GreyStone
                Technology, Inc. (the Company) as of December 31, 1999 and the
                results of operations for the three and nine month periods ended
                December 31, 1999 and 1998 and cash flows and changes in
                stockholders' equity (deficiency) for the nine months ended
                December 31, 1999. These unaudited financial statements should
                be read in conjunction with the audited financial statements and
                the other information included in the registration statement on
                Form S-4 which was declared effective by the SEC on November 12,
                1999 ("Registration Statement").

                The results of operations for the three and nine month periods
                ended December 31, 1999 are not necessarily indicative of the
                results of operations for the year ending March 31, 2000.


Note 2 - The Merger and other matters
                On December 27,1999 a merger between Express Capital Concepts,
                Inc. and GreyStone Technology, Inc. was completed, whereupon
                Express Capital Concepts was renamed GreyStone Digital
                Technology, Inc., underwent a 1-for-41.66667 reverse stock split
                (which reduced its issued and outstanding common stock to
                480,000 shares), changed the par value of the stock from $0.0001
                to $0.001 per share, and reduced the total authorized common
                stock from 500,000,000 shares to 30,000,000 shares.
                Simultaneously, 15,211,627 shares of common stock were issued to
                GreyStone Technology, Inc. common stock holders. The transaction
                has been accounted for as a reverse acquisition, wherein
                GreyStone Technology, Inc., the operating company, is treated as
                the acquirer for reporting purposes. The Balance sheets,
                statements of shareholders equity (deficiency) and cash flow are
                consolidated between GreyStone Digital Technology, Inc., and
                GreyStone Technology, Inc. as of December 31, 1999. All
                significant inter-company accounts and transactions are
                eliminated in consolidation.


Note 3 - Notes Receivable and Accrued Interest
                Notes receivable at December 31, 1999 consisted of a $500,000,
                9% note scheduled to mature on February 21, 2000. Additionally,
                the company loaned $20,000 on August 6, 1999, $10,000 on
                September 22,1999 and $20,000 on November 17,1999 to the
                Pointe-Force Company, Inc. and its principal. All loans are for
                a one-year term and bear interest at a rate of 8.75% per year.

Note 4 - Earnings (loss) per share:
                Effective March 31, 1998, the Company adopted the provisions of
                Statement of Financial Accounting Standards No. 128, Earnings
                per Share ("SFAS 128"), which requires the presentation of
                "basic" and "fully-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 the
                Registration Statement.

                Since the Company had losses applicable to common stock in the
                three and nine month periods ended December 31, 1999 and 1998,
                the assumed effects of the exercise of outstanding stock options
                and warrants were anti-dilutive and, accordingly, dilutive per
                share amounts have not been presented in the accompanying
                unaudited statements of operations. Such options and warrants
                could potentially dilute basic earnings per share in the future.


Note 5 - Segment reporting:
                Effective March 31, 1999, the Company adopted the provisions of
                Statement of Financial Accounting Standards No. 131, Disclosures
                about Segments of an Enterprise and Related Information ("SFAS
                131"). SFAS 131 established standards for the way that public
                enterprises report financial and descriptive information about
                reportable operating segments in annual financial statements and
                interim financial statements issued to stockholders. SFAS 131
                supersedes SFAS 14, Financial Reporting for Segments of a
                Business Enterprise, but retains the requirement to report
                information about major customers.

                Information on industry segments are scheduled below:

Note 6 - Warrants:
                The Company has issued warrants in conjunction with the sale of
                convertible notes payable, assisting the Company in acquiring
                capital, the extending of loans, as an incentive to equity
                investors and as part of the consideration paid to various

                consultants. Based on the provisions of Statement of Financial
                Accounting Standards No. 123, "Accounting for Stock-Based
                Compensation" ("SFAS 123") using the Black-Scholes option
                pricing model and assuming a risk-free interest rate of 6%,
                expected warrant lives of one to four years, expected volatility
                of 5% and dividends of 0%, the compensation expense relating to
                the warrants issued was $225,700 and $165,100 for the nine
                months ended December 31, 1999 and 1998, respectively. Each
                warrant entitles the holder to purchase one share of common
                stock upon exercise. The warrants expire at various dates from
                2002 through 2008. Additional information regarding warrants
                outstanding at December 31, 1999 and changes in outstanding

Note 7 - Income taxes:
                The Company had net operating loss carry forwards at December
                31, 1999 of approximately $31,000,000 available to reduce future
                Federal taxable income and approximately $11,800,000 available
                to reduce state taxable income, if any. The net operating loss
                carry forwards expire between 2006 and 2019 for Federal tax
                purposes and 2000 and 2004 for state tax purposes. The related
                deferred tax assets were fully reserved through valuation
                allowances at December 31, 1999 and 1998 and, accordingly, there
                was no provision or credit for income taxes.

                The expected Federal income tax benefit, computed based on the
                Company's pre-tax loss and the statutory Federal income tax
                rate, was approximately $1,235,000 for the nine months ended
                December 31, 1999. The potential benefits were eliminated
                through equivalent increases in the Company's valuation
                allowance primarily for deferred tax assets arising from net
                operating loss carry forwards (see Note 10 of the notes to the
                audited financial statements of the Company which are included
                in the Registration Statement).

                Statement, the Company has two incentive stock option ("ISO")
                plans - the "1991 Plan" and the "1994 Plan". In addition, the
                Company issued nonqualified stock options ("NSOs") in 1994, 1995

                of NSO stock options under the provisions of SFAS No. 123 was

                In the opinion of management, if compensation cost for the stock

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE THREE MONTHS ENDED DECEMBER 31, 1999 AND 1998

Revenues for the three months ended December 31, 1999 were $381,286 as compared
to $563,354 for the same three months ended December 31, 1998. During both of
these periods, the Government Strategic Business Unit (SBU) generated
essentially all revenues. The sales decline of $182,068 in the Government SBU
between periods was primarily the result of a delay in funding of government
contracts. The company redirected a portion of the
<PAGE>   15
Page 15


Government SBU engineering staff to product development efforts in support of
the RAGE 2.0. Although revenues are expected from the sale of commercial
entertainment products, GreyStone expects to incur additional losses as it
continues to market and develop its entertainment products.

Costs of revenues increased 18% to $293,481 for the three months ended December
31, 1999, compared to $249,469 for the same three-month period in 1998. As a
percentage of revenues, costs of revenues were 77% in 1999 compared to 44% for
the same three-month period in 1998. Cost of revenues increased during the
current period due to an increase in material/subcontract costs for computers
and software tools in support of contractual work. Additionally, travel costs
were higher than usual, primarily as a result of GreyStone's support of overseas
military experiments.

The components that made 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 from period to period and are highly
dependent on such factors as the nature of the work performed, location and
duration of the work (i.e., company versus customer site), who performed the
work (i.e., company personnel versus subcontractors) and who provided any
required equipment (i.e., company versus customer).

Marketing and sales expenses were $203,831 or 54% of revenues for the three
months ended December 31, 1999 compared to $149,633 or 27% of revenues for the
same three month period in 1998. The increase was in the Government SBU.
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. 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 by 196% to $220,401 for the three
months ended December 31, 1999, as compared to $74,562 for the same three-month
period in 1998. The increase of research and development expenses was in the
Government SBU and reflects development costs for RAGE 2.0 and the Unmanned Air
Vehicle (UAV) Toolkit.

General and administrative expenses increased to $1,034,287 for the three months
ended December 31, 1999, compared to $661,106 for the same three month period in
1998, resulting in an increase of $373,181. General and administrative increases
were the result of legal, accounting and other related costs associated with the
completion of the business combination with Express Capital Concepts, Inc. in
December 1999. Additionally, there was an increase in compensation expense
associated with the issuance of warrants and compensatory stock options.

Interest expense was $2,537 for the three months ended December 31, 1999,
compared to $19,093 for the same three month period ended in 1998, a decline of
$16,556 and reflects the paying down and/or conversion of certain company
indebtedness to equity.

The net loss of $1,373,251 increased by $782,742 or 133% from the $590,509 net
loss reported in the previous period in 1998. In summary, during the current
period, revenues were

down by $182,068 or 32%, while total expenses, including
interest, increased by $600,674 or 52%.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE NINE MONTHS ENDED DECEMBER 31, 1999 AND 1998

Revenues for the nine months ended December 31, 1999 were $1,331,641, as
compared to $1,601,962 for the same nine months ended December 31,1998. During
both of these periods, the Government Strategic Business Unit (SBU) generated
essentially all revenues, with $1,230,048 of revenue in the current nine month
reporting period and $1,582,269 in the nine months ending December 31,1998,
while Commercial revenue was $55,999 in the current period and $14,615 in the
previous period. The sales decline in the Government SBU between periods was
primarily the result of a delay in funding of government contracts. The company
redirected a portion of the Government SBU engineering staff to product
development efforts in support of the RAGE 2.0 product release. Commercial
revenues of $55,999 in the current reporting period were the result of work done
by GreyStone on a special project for Legoland Windsor Park Ltd. Although
revenues are expected from the sale of commercial entertainment products,
GreyStone expects to incur additional losses as it continues to market and
develop its entertainment products.

Costs of revenues declined 10 % to $813,270 for the nine months ended December
31, 1999, compared to $901,426 for the same nine-month period in 1998. As a
percentage of revenues, costs of revenues were 61% in 1999 compared to 56% for
the same nine-month period in 1998. Cost of revenues increased during the
current period due to an increase in material/subcontract costs for computers
and software tools in support of contractual work. Additionally, travel costs
were higher than usual primarily as a result of GreyStone's support of overseas
military experiments.

The components that made 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 (i.e., company versus customer site), who performed the
work (i.e., company personnel versus subcontractors) and who provided any
required equipment (i.e., company versus customer).

Marketing and sales expenses were $561,871 or 42% of revenues for the nine
months ended December 31, 1999 compared to $573,795 or 36% of revenues for the
same nine month period in 1998. Although there is a net decline of $11,924 in
company marketing and sales expenses in the current period, Government SBU
marketing and sales expenses actually increased by $91,161, while Commercial SBU
marketing and sales expenses decreased by $103,085. 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. 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 declined slightly to $750,620 for the nine
months ended December 31, 1999, as compared to $759,148 for the same nine-month
period in 1998.


<PAGE>   17
Page 17


Although there was a net decline of $8,528 in company research
and development costs, Government SBU research and development costs actually
increased by $288,920 as a result of development efforts on RAGE 2.0. A decline
of research and development expenses in the commercial SBU of $297,448 reflects
the completion of development of the XS-G game.

General and administrative expenses increased to $2,283,179 for the nine months
ended December 31, 1999, compared to $1,565,421 for the same nine month period
in 1998, resulting in an increase of $717,758. General and administrative
increases were the result of legal, accounting and other related costs
associated with the completion of the business combination with Express Capital
Concepts, Inc. in December 1999. Additionally, there was an increase in
compensation expense associated with the issuance of warrants and compensatory
stock options.

Interest expense was $9,811 for the nine months ended December 31, 1999,
compared to $63,257 for the same nine month period ended in 1998, a decline of
$53,446 and reflects the paying down and/or conversion of certain company
indebtedness to equity.

The net loss of $3,087,110 increased by $826,025 or 37% from the $2,261,085 net
loss reported in the previous period in 1998. In summary, during the current
period, revenues were down by $270,321 or 17%, while total expenses, including
interest, increased by $555,704 or 14%.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities for the nine months ended December 31,
1999 was $3,129,427, whereas cash used for the nine months ended December 31,
1998 was $1,092,584. Cash flow from operations decreased during the first nine
months of 1999 compared to the first nine months of 1998 due to an increase in
accounting, legal and other related expenses associated with the completion of
the business combination with Express Capital Concepts, Inc. in December 1999.
Additionally, cash was used to reduce accounts payable and accrued expenses by
$437,793 during the current period, increase other assets by $14,356, and
accounts receivable increase by $21,194.

Net cash used in investing activities increased by $250,228 for the nine months
ended December 31, 1999, due to expenditures for software licenses and equipment
of $250,228. Net cash provided by financing activities increased by $3,790,271
for the nine months ended December 31,1999, and was primarily the result of
issuing common stock of $3,246,629 and the exercise of $1,694,452 of warrants
for common stock. This was offset by repayment on notes and loans payable of
$600,810, of which $58,000 was to the principal stockholder and $140,810 were to
officers, and issuances of notes receivable of $550,000 of which $50,000 was to
a related party.

At December 31, 1999, the Company had $1,206,096 in cash and cash equivalents.
The Company anticipates that in the future, it will need to obtain debt or
equity financing to continue its operations for at least the next 12 months.
