        to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not
        include all of the information and footnotes required by generally
        accepted accounting principles for complete financial statements. In the
        opinion of management, all adjustments (consisting of normal recurring
        accruals) considered necessary for a fair presentation have been
        included. Operating results for the three month period ended June 30,
        2000 are not necessarily indicative of the results that may be expected
        for the year ended March 31, 2001. 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, 2000.

        The results of operations and cash flows for the three months ended June
        30, 1999 occurred before the merger and are for GreyStone Technology,
        Inc. only.



Note 2 - The merger and other matters:

        On December 27, 1999 a merger between a subsidiary of Express Capital
        Concepts, Inc. and GreyStone Technology, Inc. was completed, whereupon
        Express Capital Concepts also 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, reduced the total authorized common stock from 500,000,000 shares
        to 30,000,000 shares, and was renamed GreyStone Digital Technology,
        Inc.. Simultaneously, 15,211,627 shares of common stock of GreyStone
        Digital Technology, Inc. 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 operations, stockholders' equity and cash flows
        are consolidated between GreyStone Digital Technology, Inc, and
        GreyStone Technology, Inc. as of June 30, 2000. All significant
        inter-company accounts and transactions are eliminated in consolidation.


Note 3 - Notes receivable and accrued interest:

        Notes receivable at June 30, 2000 consists of two notes from an
        individual. The notes were originally due February 20, 2000, accrue
        interest at 9% and are collateralized by common stock in a company owned
        by the individual. The maturity date of the notes was extended to May
        20, 2000 and subsequently further extended to August 20, 2000.

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,
        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 Form 10-K
        for the fiscal year ended March 31, 2000.

        Since the company had losses applicable to common stock in the three
        month period ended June 30, 2000 and 1999, 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 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 ten years, expected
        volatility of 5% to 60% and dividends of 0%, the compensation expense
        relating to the warrants issued was $614,513 and $88,800 for the three
        months ended June 30, 2000 and 1999, respectively. Each warrant entitles
        the holder to purchase one share of common stock upon exercise. The
        warrants expire at various dates from 2002 through 2010. Additional
        information regarding warrants outstanding at June 30, 2000 and changes
        in outstanding warrants during the three months then ended follows:

Note 7 - Income taxes:

        The Company had net operating loss carry forwards at June 30, 2000 of
        approximately $34,100,000 available to reduce future Federal taxable
        income and approximately $10,400,000 available to reduce state taxable
        income, if any. The net operating loss carryforwards expire between 2006
        and 2020 for Federal tax purposes and 2001 and 2005 for state tax
        purposes. The related deferred tax assets were fully reserved through
        valuation allowances at June 30, 2000 and March 31, 2000 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 $559,000 for the three months ended June 30, 2000. The
        potential benefits were eliminated through equivalent increases in the
        Company's valuation allowance primarily for deferred tax assets arising
        from net operating loss carryforwards (see Note 11 of the notes to the
        audited financial statements of the Company which are included in the
        Form 10-K for the fiscal year ended March 31, 2000).

Note 8 - Stock option plans:

        As further explained in Note 13 of the notes to the audited financial
        statements, which are included in the Form 10-K for the fiscal year
        ended March 31, 2000, the Company has two stock option plans - the "1991
        Plan" and the "1994 Plan". In addition to incentive stock options (ISOs)
        issued under the plans, the Company issued nonqualified stock options
        (NSOs) outside of the plans in 1994, 1995, 1997 and 1998. Information

</TABLE>

        The amount of compensation expense recognized for the three months ended
        June 30, 2000 and 1999 relating to the granting of NSO stock options
        under the provisions of SFAS No. 123 was $12,600 and $4,200 for the
        three months ended June 30, 2000 and 1999, respectively.

        In the opinion of management, if compensation cost for the stock options
        granted to employees had been determined based on the fair value of the
        options at the grant date under the provisions of SFAS No. 123 using the
        Black-Scholes option pricing model and assuming a risk-free interest
        rate of 6%, expected option lives of one to ten years, expected
        volatility of 5% to 60% and dividends of 0%, the Company's pro forma net
        loss arising from such computations would have been increased by
        approximately $132,640 and $177,000 for the three months ended June 30,
        2000 and 1999, respectively.

Note 9 - Related party transactions and balances:

        In July 1999, a professional services agreement was made between the
        company and The Pointe-Force Company, Inc. ("Pointe-Force"), an entity
        controlled by the spouse of a director of GreyStone. Pointe-Force
        supports the company in the areas of mergers and acquisitions, strategic
        planning, corporate financing and relations with the investment
        community. Under this one-year advisory services agreement, Pointe-Force
        is compensated in the amount of $11,000 per month, not including
        expenses. Additionally, the company loaned $20,000 on August 6, 1999,
        $10,000 on September 22, 1999 and $20,000 on November 17, 1999 to
        Pointe-Force and GreyStone's director. All loans are for a one-year term
        and bear interest at a rate of 8.75% per year. The maturity date of the
        loan that was due on August 6, 2000, is currently being extended.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 2000 AND 1999

Revenues for the three months ended June 30, 2000 were $540,044 as compared to
$459,570 for the three months ended June 30, 1999. During both of these periods,
the Government Strategic Business Unit (SBU) generated essentially all revenues.
The sales increase of $80,474 (or approximately 18%) between the periods was
primarily the result of additional tasking on current contracts and the
expansion of our government customer base. During this reporting period, the
Government SBU expanded its tasking on current contracts supporting the
military's Joint Forces SemiAutomated Forces simulation software and the Joint
Strike Fighter program. Additional delivery orders under GreyStone's Battlefield
Visualization contract with the U.S. Navy's Space and Naval Warfare Systems
Center - San Diego (SPAWARSYSCEN - San Diego)  have also been awarded for new
engineering services work with the Marine Corps Warfighting Laboratory, Naval
Warfare Development Center, Naval Air Warfare Center Weapons Division and the
Space and Naval Warfare Systems Advanced Concepts and Technology Division. As of
June 30, 2000, the company's backlog was approximately $1,087,000. All of the
backlog is expected to be completed within the current fiscal year ending March
31, 2001. In March 1999, GreyStone was awarded the five year $15.1 million
delivery order contract from SPAWARSYSCEN - San Diego. Approximately $2.6
million in delivery orders have been authorized under this contract through June
30, 2000, leaving an available ceiling of approximately $12.5 million during the
remaining 43 months of the contract.


During the next twelve months, GreyStone's Commercial SBU expects to generate
revenues from the sale of its new Commercial entertainment product, the Mercury
motion base platform featuring the XSG game. The Commercial SBU may incur
additional losses during the next twelve months as it introduces its new
entertainment products to the market.

Cost of revenues increased to $423,502 for the current quarter compared to
$226,844 for the first quarter of the previous year. As a percentage of
revenues, costs of revenues were 78% in the current quarter compared to 49% for
the comparable quarter in the previous year. Cost of revenues increased in the
current quarter over the previous year's quarter due to an increase in purchased
engineering services costs in support of new contractual work and an increase in
the use of subcontractors for new work. Additionally, direct travel costs were
higher as a result of GreyStone's support of overseas military experiments. 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 significantly 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 $258,732 or 48% of revenues in the current
quarter compared to $166,511 or 36% of revenues for like quarter in the previous
year, an increase of $92,221. The increase in marketing and sales expenses was
due to the greater level of marketing effort of the Government SBU in support of
RAGETM, the company's real-time visualization software product and related
engineering services. 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. Marketing and sales expenses will vary from
period to period as they depend highly upon the extent and manner in which the
company alters its efforts regarding potential contract opportunities during the
reporting period.

Research and development expenses increased to $340,358 for the current year's
quarter compared to $237,302 for the previous year's quarter. The increase is in
the Commercial SBU and reflects work on a new motion base for the Mercury based
entertainment system, creating a new title for play on the Mercury system and
developing a 3D Virtual Info-Space(TM) environment.

General and administrative expenses increased to $1,189,188 compared to $515,968
for the previous year's quarter, an increase of $673,220. Of the $673,220
increase, $534,113 was a non-cash compensation expense increase associated with
the issuance of warrants and compensatory stock options. The remainder of the
increase was for consulting fees and public relations expenses.

Other income of $27,407 consisted of interest income, including $14,553 of
interest income from related parties' notes. Interest expense declined by $7,182
and was primarily the result of the conversion into stock of notes payable to
the principal stockholder.

The net loss of $1,644,329 increased by $950,092 or 137% from the $694,237 net
loss reported in the previous years first quarter. In summary, during the
current year, revenues were up by $80,474 or 18%. Total expenses and other
income (expense), increased by $1,030,566 or 89%.

GreyStone has previously cautioned that quarterly revenues and operating results
vary significantly and that period-to-period comparisons of its revenues and
operating results are not necessarily meaningful and should not be relied upon
as indications of future performance.


INVESTMENTS AND CAPITAL RESOURCES

On January 14, 2000, GreyStone executed a letter of intent for the acquisition
of a company that designs, builds, and sells forensic surveillance, mobile
intelligence, and communications platforms on a customized contract basis
primarily for domestic and international customers in law enforcement,
intelligence and military services. At the time of the filing of this report the
two companies are in discussions concerning the details of the form of
relationship. The transaction would allow GreyStone to use and expand our core
technologies and record revenues from the sale of products to a broad new
spectrum of customers. Our two companies have teamed for the recent submittal of
a proposal for forensic vehicles and command and control systems for a national
security agency in South America.

In support of the developing relationship between GreyStone and the target
company, GreyStone loaned the president (who is the sole shareholder) of the
company $500,000 in November 1999 and an additional $100,000 in February 2000.
The loans were originally due February 20, 2000. The maturity date of the loans
was extended to May 20, 2000 and subsequently extended to August 20, 2000. The
loans are collateralized by all of the borrower's stock in the target company.
In June 2000 GreyStone purchased forensic vehicle equipment from the target
company in the amount of $330,000 and paid the company $135,000 for the right to
receive future payment on invoices to be generated by the target company upon
the completion of work in progress. Until the business combination is complete,
GreyStone may elect in its sole discretion to provide more money to the target
company in an amount of approximately $500,000 during the remainder of the
business year ending March 31, 2001.

LIQUIDITY

GreyStone has incurred losses in each fiscal year since 1993, and as of June 30,
2000, GreyStone had an accumulated deficit of $39,308,840. To finance its
business plan and historic negative cash flow, GreyStone has



<PAGE>   15
Page 15



continually needed to obtain debt and equity financing on a private basis and to
satisfy creditors with stock rather than by payment in cash to enable it to
develop its products. These losses have been primarily due to lack of any
significant entertainment revenues, substantial research and development program
expenses for Commercial and Government business units, and other costs incurred
for the development and introduction of GreyStone's products. Almost all of
GreyStone's sales have been in the government business area, which provides low
profit margins from which GreyStone has not been able to recover the costs of
its research and development programs. Although revenues are expected from the
sale of entertainment products, GreyStone is likely to incur additional losses
as it continues to market and develop its products. No assurance can be given
that GreyStone will ever derive material revenues from entertainment products or
that the sale of its products will ever be profitable.

Net cash used in operating activities for the three months ended June 30, 2000
was $1,242,731, which was essentially unchanged from the $1,261,308 of cash used
for operating activities in the three months ended June 30, 1999. Although the
net loss for the quarter was $1,644,329, an increase of $950,092 from the
previous reporting quarter net loss amount of $694,237, non cash outlays for
depreciation and compensation expense in the current quarter were $662,763, as
compared to $133,877 in the previous quarter, an increase of $528,886.
Additionally, cash was used to reduce accounts payable and accrued expenses by
$433,467, increase other assets by $15,120 and accounts receivable decreased by
$171,735.

Net cash used in investing activities was $515,871 during the current three
month period compared to $33,646 for the same reporting period in business year
2000. In addition to the transactions with the acquisition candidate discussed
above, current period investing activities included purchases of software
licenses and equipment of $50,871.

Net cash provided by financing activities was $4,449,253 in the current period
compared to $2,159,715 for the previous comparable period. The $4,449,253 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 will be used by the company for general
corporate purposes.

At June 30, 2000, the company had $2,858,050 in cash and cash equivalents, as
compared to $167,299 for the fiscal year ended March 31, 2000. Management
anticipates that in the future it will need to continue to obtain debt or equity
financing and, if GreyStone is unable to generate significant sales, then
GreyStone faces the risk of not having enough money or other resources to
continue to operate its current business plan. If additional money is needed and
is not available, then GreyStone could be forced to curtail product development
and the expansion of its operations.
