                    Report of Independent Public Accountants

To the Board of Directors of
Arista Knowledge Systems, Inc.:

We have audited the accompanying balance sheets of Arista Knowledge Systems Inc.
(a Delaware corporation in the development stage) as of December 31, 1999 and
1998, and the related statements of operations, stockholders' deficit and cash
flows for the years then ended and for the period from inception (July 14, 1997)
through December 31, 1999. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Arista Knowledge Systems, Inc.
as of December 31, 1999 and 1998, and the results of its operations and its cash
flows for the years then ended and for the period from inception (July 14, 1997)
through December 31, 1999 in conformity with accounting principles generally
accepted in the United States.

ARISTA KNOWLEDGE SYSTEMS, INC.
(A DEVELOPMENT STAGE COMPANY)

Notes to Financial Statements
December 31, 1999


1. Organization and Operations of the Company

Arista Knowledge Systems, Inc. (the "Company") was originally incorporated in
Oregon on July 14, 1997 under the name Eduventures, Inc. Upon resolutions
amending and restating the Company's Certificate of Incorporation, the Company
was reincorporated in Delaware and the name of the Company was changed to Arista
Knowledge Systems, Inc. effective December 25, 1998. The Company provides
software solutions for the management of Internet, network based and other
technology driven learning activities.

In March 2000, the Company changed its fiscal year end from March 31 to December
31. The financial statements presented herein have been adjusted to reflect the
change in fiscal year end.

The Company is subject to a number of risks including, but not limited to, the
need for additional financing to fund its future growth and development of its
principal products, uncertain profitability and competition from larger
companies, and ability to attract and retain employees. As of December 31, 1999,
the Company has not completed the development of its principal product and has
incurred operating losses since inception. Management's projections indicate
that additional cash will be required to fund operations through December 31,
2000. As discussed in Note 11, the Company was acquired by DigitalThink, Inc.
(DigitalThink) in July 2000. As the parent of the Company, DigitalThink has
committed to provide the funds required for continued operations of the Company
during fiscal year 2000.

2. Summary of Significant Accounting Policies

        Use of Estimates in Preparation of Financial Statements

        The preparation of financial statements in conformity with accounting
        principles generally accepted in the United States requires management
        to make estimates and assumptions that affect the reported amounts of
        assets and liabilities and disclosure of contingent assets and
        liabilities at the date of the financial statements and the reported
        amounts of revenues and expenses during the reporting period. Actual
        results could differ from those estimates.

        Cash and Cash Equivalents

        The Company considers all highly liquid investments with an original
        maturity of three months or less from the date of purchase to be cash
        equivalents. As of December 31, 1999 and 1998, the Company's cash and
        cash equivalents consisted of cash deposited in checking and money
        market accounts.

        Restricted Cash

        Restricted cash is in the form of a certificate of deposit with a bank
        and relates to a letter of credit issued by the bank securing a lease
        deposit on the Company's current facilities.

        Accounting for the Impairment of Long-Lived Assets

        The Company periodically assesses the realizability of its long-term
        assets in accordance with Statement of Financial Accounting Standards
        ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets
        and for Long-Lived Assets to be Disposed Of" ("SFAS No. 121"). SFAS No.
        121 establishes the recognition and measurement standards related to the
        impairment of long-lived assets. Recognition of asset impairment
        writedowns has not had a material impact on the Company's financial
        statements for any periods presented.

        Research and Development Costs


<PAGE>   10

        Research and development expenditures are charged to operations as
        incurred. SFAS No. 86, "Accounting for Costs of Computer Software to be
        Sold, Leased, or Otherwise Marketed," requires the capitalization of
        certain software development costs subsequent to the establishment of
        technological feasibility. Based on the Company's product development
        process, technological feasibility is established upon completion of a
        working model. Costs incurred by the Company between completion of a
        working model and the point at which the product is ready for general
        release have been insignificant. Through December 31, 1999, all research
        and development costs have been expensed.

        Property and Equipment

        Property and equipment are stated at cost. Depreciation is computed
        using the straight-line method over the estimated useful lives of the
        assets, which typically range from three to five years. Leasehold
        improvements are amortized over the shorter of the lease term or useful
        life of the related asset.

        Included in property and equipment at December 31, 1999 and 1998 are
        assets acquired under capital lease obligations with an original cost of
        approximately $94,000. Accumulated amortization on the leased assets was
        approximately $15,000 and $3,000 at December 31, 1999 and 1998,
        respectively.

        Property and equipment consists of the following at December 31, 1999
        and 1998:

</TABLE>

        Revenue Recognition

        In July 1997, the Company entered into an agreement with a customer to
        develop certain web-based educational content. In October 1997, the
        Company subcontracted the development services under this agreement (see
        Note 8). The subcontract agreements entitled the Company to fees
        comprising 2.5 percent to 10 percent of the proceeds received under the
        original contract. The Company was the principal in this arrangement,
        and was responsible for performance of the services and bore the risk of
        credit loss. Consequently, revenue under this contract is recognized at
        the gross amount of the billings under the contract when modules are
        delivered in accordance with the original agreement. Cost of revenue is
        the difference between the gross amount of the billing and the Company's
        margin percentage based on its arrangements with subcontractors. All
        revenue recorded by the Company for the period from inception through
        December 31, 1999 has been derived from this contract agreement.

        Stock-Based Compensation

        In 1998, the Company adopted the disclosure requirements of Statement of
        Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for
        Stock-Based Compensation." As permitted under this standard, the Company
        has elected to follow Accounting Principles Board Opinion No. 25,
        "Accounting For Stock Issued to Employees" in accounting for its stock
        options and other stock-based employee awards (see Note 7).

        Fair Value of Financial Instruments



<PAGE>   11

        The carrying amounts of the Company's financial assets and liabilities,
        including cash and cash equivalents, accounts receivable, accounts
        payable, capital leases, and short-term borrowings, at December 31, 1999
        and 1998, approximate fair value because of the short maturity of these
        instruments.

        The fair value of the Company's long term borrowings equaled their
        carrying value at December 31, 1999.

        Comprehensive Income (Loss)

        In June 1997, the Financial Accounting Standards Board ("FASB") issued
        SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes
        standards for reporting and display of comprehensive income and its
        components in a full set of general purpose financial statements. The
        objective of SFAS No. 130 is to report a measure of all changes in
        equity of an enterprise that result from transactions and other economic
        events of the period other than transactions with stockholders
        ("comprehensive income"). Comprehensive income is the total of net
        income and all other non-owner changes in equity. For all periods from
        inception (July 14, 1997) to December 31, 1999, the Company's
        comprehensive loss was equal to its net loss.


        Net loss attributable to common stock per share

        Basic and diluted net loss attributable to common stock per share are
        presented in conformity with SFAS No. 128 ("SFAS 128"), "Earnings Per
        Share," for all periods presented. Pursuant to SEC Staff Accounting
        Bulletin No. 98, common stock and convertible preferred stock issued or
        granted for nominal consideration prior to the anticipated effective
        date of an IPO must be included in the calculation of basic and diluted
        net loss attributable to common stock per share as if such stock had
        been outstanding during the years ended December 1998 and 1999. To date
        the Company has had no issuances or grants for nominal consideration.

        In accordance with SFAS 128, basic net loss attributable to common stock
        per share has been computed using the weighted average number of shares
        of common stock outstanding during the period, less shares subject to
        repurchase. Diluted net loss attributable to common stock per share is
        computed on the basis of the weighted average number of shares and
        common equivalent shares outstanding during the period. Common
        equivalent shares result from the assumed exercise of outstanding stock
        options that have a dilutive effect when applying the treasury stock
        method. The Company has excluded all convertible preferred stock,
        outstanding stock options and shares subject to repurchase from the
        calculation of diluted net loss attributable common stock per share for
        the years ended December 31, 1999 and 1998, because all such securities
        are antidilutive. Accordingly, diluted net loss attributable to common
        stock per share approximates basic net loss attributable to common stock
        per share for all years presented.

        The total number of shares excluded from the calculations of diluted net
        loss attributable to common stock per share were 5,738,649 and 3,393,297
        shares for the years ended December 31, 1999 and 1998, respectively.

        Subsequent to December 31, 1999, the Company issued warrants to purchase
        1,403,482 shares of the Company's common stock and granted stock options
        to purchase 1,658,267 shares of the Company's common stock. These grants
        would have changed the number of common shares and potential common
        shares outstanding at December 31, 1999, if the transactions had
        occurred before the end of the period.

        The following table presents the calculation of basic and diluted net

        Segment Reporting

        In June 1997, the FASB issued SFAS No. 131 ("SFAS 131"), "Disclosures
        About Segments of an Enterprise and Related information." SFAS 131 was
        adopted by the Company beginning on January 1998. SFAS 131 establishes
        standards for disclosures about operating segments, products and
        services, geographic areas and major customers. The Company is organized
        and operates as one operating segment. Revenue by geographic area is
        attributed to the country from which the sale is made. The Company's
        chief decision maker monitors the Company's operations based upon the
        information reflected in the accompanying combined statements of
        operations. To date all of the Company's transactions have been
        originated from one geographic area, the United States. Currently all
        long-lived assets are located in one geographic area, the United States.


3. Line of Credit

In February 1999, the Company entered into an equipment line of credit (the
"Equipment Line") with a leasing firm providing for total available borrowings
up to $200,000 to finance the purchase of eligible equipment through December
31, 1999. The effective interest rate on each advance is 10.67 percent.
Borrowings under each line are payable in 36 monthly installments of principal,
plus interest, beginning on the next month after each borrowing. At the end of
the payment term, the Company will be required to remit a balloon payment of
accrued interest equal to 15 percent of the total amount borrowed. Borrowings
under the Equipment Line are secured by the underlying assets purchased with the
monies borrowed under the agreement. The Agreement requires the Company to
comply with certain affirmative covenants. As of December 31, 1999, the Company
had $62,364 outstanding under the Equipment Line.

Aggregate principal maturities under the Equipment Line are as follows:

4. Notes Payable and Accrued Interest Due to a Related Party

In July 1999, the Company entered into a note payable agreement (the "Note")
with a stockholder of the Company (collectively, with its subsidiaries,
"Safeguard") to borrow up to $1.5 million for working capital purposes. Interest
on the Note accrues at prime plus 1 percent (9.5 percent at December 31, 1999)
and was approximately $60,000 at December 31, 1999. Principal and accrued
interest on this Note are payable upon the earlier of (i) July 15, 2001, (ii)
the consummation of an initial public offering ("IPO") by the Company or (iii)
the sale of substantially all of the Company's assets or outstanding shares of
capital stock. At any time on or after July 16, 2001, and at the option of
Safeguard, any remaining outstanding principal and accrued interest on the Note
may be converted into shares of the Company's Series B Preferred Stock at a
conversion price of $1.10 per share. Borrowings under the Note are secured by
virtually all of the Company's assets. As of December 31, 1999 the Company had
$1.5 million outstanding and no available borrowings under the Note.
<PAGE>   12

5. Notes Payable

In December 1999, the Company entered into a bridge loan agreement (the "Loan")
with a lender providing for borrowings up to $2 million to be used for working
capital purposes through April 30, 2000. Interest on the Loan is at prime plus
1.5 percent (10 percent at December 31, 1999) and is payable monthly based on
the average daily outstanding balance under the Loan for the preceding month.
Principal and accrued interest are payable upon the earlier of (i) April 30,
2000 or (ii) an equity event, as defined in the agreement. Borrowings under the
Loan are secured by virtually all of the Company's assets. As of December 31,
1999, the Company had no monies outstanding under the Loan and had $2 million
available for future borrowings. As of May 16, 2000, the Company had $1.7
million outstanding under this agreement.

6. Commitments

The Company leases its facilities and certain office equipment under operating
and capital lease agreements expiring through August 2002. Rent expense for all
operating leases totaled $178,457 and $89,226 for the year ended December 31,
1999 and 1998, respectively.

During the year ended December 31, 1998, the Company entered into a capital
lease obligations of approximately $94,000 for various equipment. These capital
leases provide for monthly payments ranging from $207 to $2,245.

Minimum future lease payments under all noncancellable capital and operating
leases as of December 31, 1999 are as follows:

7. Mandatorily Redeemable Convertible Preferred Stock

The Company has authorized the issuance of up to 10,000,000 shares of preferred
stock of which 6,825,000 shares have been designated as Series A Preferred Stock
("Series A"). Of the 6,825,000 shares designated as Series A, 2,275,000 have
been reserved for stock dividends on the Series A. In June 1998, the Company
raised $3,934,389, net of issuance costs of $65,061, through the sale of
4,550,000 shares of Series A at an issuance price of $0.879 per share.

In July 1999, the Company authorized 2,500,000 shares be designated as Series B
Preferred Stock ("Series B", collectively with the Series A, the "Preferred
Stock"). No shares of Series B preferred stock have been issued to date.

The rights and preferences of the Preferred Stock are as follows:

   - If and when dividends or distributions are declared by the Board of
     Directors, the holders of the Preferred Stock shall be entitled to receive
     cumulative dividends at the rate of $0.07, per annum per share. No
     dividends have been declared by the Company

   - Beginning four years after the respective original issue date of the Series
     A and Series B, the holders of the outstanding Preferred Stock shall be
     entitled to receive quarterly dividends payable in additional shares of
     Preferred Stock. On each quarterly payment date, such holders shall be
     entitled to receive 0.02 shares of Preferred Stock for each share of
     Preferred Stock held on the original issue date.

   - In the event of any liquidation, dissolution or winding up of the
     corporation, either voluntary or involuntary, the holders of the Preferred
     Stock will be entitled to receive out of the assets of the corporation, for
     each share, prior and in preference to any distribution to the holders of
     the common stock, the greater of (i) an amount equal to the original
     purchase price of the Preferred Stock plus interest equal to 8% per annum
     compounded annually from the issue date of each share or (ii) the amount
     that would be received with respect to one share of Preferred Stock if all
     shares were converted into common stock, as adjusted. In addition, the
     holders of Preferred Stock shall be entitled to an amount equal to all
     declared by unpaid dividends. The liquidation preference for Series A and
     Series B at December 31, 1999 was $0.98 per share and $1.10 per share,
     respectively.

   - Each holder of the Preferred Stock is entitled to a number of votes equal
     to the number of shares of common stock into which such stockholder's
     shares of convertible preferred stock could be converted.

   - Upon closing of an IPO of common stock in which aggregate proceeds are at
     least $15 million and the price per share is at least $3.52 per share, all
     outstanding shares of Preferred Stock will automatically convert into
     shares of common stock at the conversion ratio in effect on such date. At
     December 31, 1999 and 1998, each share of Preferred Stock was convertible
     into one share of common stock.

   - Each holder of Preferred Stock may, at any time, and from time to time,
     convert any or all of such holder's shares into fully-paid and
     non-assessable shares of common stock at the conversion ratio in effect at
     that date. At December 31, 1999 and 1998, each share of Preferred Stock was
     convertible into one share of common stock.

   - At any time on or after the fifth anniversary of the original issue date,
     the holders of the Preferred Stock may elect to have the outstanding
     preferred stock redeemed. The amount per share payable upon redemption on
     the Series A and Series B will be $0.879 and $1.10 per share, respectively.

        Shares Subject to Repurchase

        The Company issued 856,235 shares of common stock to certain employees
        of the Company that are subject to repurchase rights. These repurchase
        rights expire upon the earlier of (i) the closing of an IPO or (ii) the
        closing of an acquisition of the Company by a public entity. As of
        December 31, 1999, all of these shares are subject to repurchase by the
        Company at the fair

<PAGE>   13

        market value of the Company's common stock at the date of repurchase as
        determined by the Company's Board of Directors.

        Class A Common Stock

        The Company has authorized the issuance of up to 600,000 shares of Class
        A common stock ("Class A Common"). The Class A Common has the same
        rights and preferences as common stock with the exception of a
        liquidation preference. The liquidation preference entitles the holders
        of the Class A Common to $0.50 per share in the event of a liquidation,
        dissolution or winding up of the corporation, voluntary or involuntary,
        after payment of full preferential amounts to the holders of the
        Company's preferred stock and prior to any amounts being distributed to
        the remaining common stockholders. As of December 31, 1999, no Class A
        Common has been issued; however, 600,000 shares of common stock held by
        an original investor in the Company are currently convertible into Class
        A Common.

<PAGE>   14
        Warrants

        On July 15, 1999, in connection with the borrowings secured under the
        Note, the Company granted warrants to purchase 681,800 shares of Series
        B stock at $1.10 per share. The warrants are exercisable beginning in
        July 2001 and expire in July 2004. The fair value of the warrants was
        estimated using the Black-Scholes model using the following assumptions:
        risk-free interest rate of 5.8 percent, volatility of 53 percent,
        expected life of 3 years, and no expected dividends. The Company
        recorded approximately $309,000 related to the valuation of these
        warrants, which is being amortized as additional interest expense over
        the term of the Note. As of December 31, 1999, the Company had recorded
        approximately $67,000 of interest expense related to these warrants,
        which is included in interest expense in the accompanying statement of
        operations. Subsequent to year end, this warrant agreement was amended
        (see Note 11).

        On December 31, 1999, in connection with the Loan, the Company issued
        warrants to purchase 79,787 shares of common stock at $0.94 per share.
        The warrants were exercisable immediately and expire in December 2004.
        As of December 31, 1999, no warrants had been exercised. The fair value
        of the warrants was estimated using the Black-Scholes model with the
        following assumptions: risk-free interest rate of 6.14 percent,
        volatility of 80 percent, expected life of 5 years, and no expected
        dividends. The Company recognized approximately $51,000 related to the
        valuation of these warrants, which was recorded as debt issuance costs
        and included in other current assets in the accompanying balance sheet.
        In January 2000, when the Company initially borrowed monies under the
        Loan, this amount was reclassified as a discount on the Loan, and is
        being amortized as additional interest expense over the term of the
        Loan. As of December 31, 1999, no amortization had been recorded on
        these warrants.

        Stockholder Receivables

        Certain employees and founders have been issued common stock in exchange
        for full recourse stockholder notes receivables. These receivables
        accrue interest at 8 percent per annum and are payable in monthly
        installments through June 2000. As of December 31, 1999 and 1998, the
        Company had approximately $45,000 and $62,000 due from such notes
        receivables. These notes receivables are secured by the underlying stock
        issued under such arrangements.

        Stock Option Plan

        In June 1998, the Company adopted the 1998 stock option plan (the
        "Plan"). Under the Plan, the Company authorized the issuance of up to
        1,716,667 shares to employees, directors and consultants. Under the
        Plan, the Board of Directors may grant incentive and nonqualified stock
        options to employees, directors and consultants of the Company. The
        exercise price per share for a stock option cannot be less than 100
        percent of the fair market value, as determined by the Board of
        Directors, on the date of grant. Options generally vest 12.5 percent
        upon completion of six months of service by the optionee and ratably
        over a three-and-a-half year period thereafter and expire ten years
        after the date of grant.

        Stock option activity under the Plan for the years ended December 31,
        1999 and 1998 was as follows:

        The Company accounts for stock options issued to non-employees in
        accordance with SFAS 123. The compensation expense related to the value
        of options granted to non-employees has been immaterial for all periods
        presented.

        The weighted average fair value of options granted to employees during
        the years ended December 31, 1999 and 1998 estimated on the date of
        grant using the Black-Scholes option pricing model was $0.20 and $0.06,
        respectively. The fair value of the 1999 and 1998 options granted is
        estimated on the date of grant using the following assumptions:
        risk-free interest rate range of 5.87 to 5.98 percent, depending on the
        grant date, expected life of 4 years, no volatility and no expected
        dividends.

        The Company accounts for this Plan under APB 25. In accordance with APB
        25, the Company recorded compensation expense of approximately $0 and
        $37,000 for the years ended December 31, 1999 and 1998, respectively.
        Had compensation expense for the Plan been determined consistent with
        SFAS 123, the Company's net loss attributable to common stock would have
        been increased to the following pro forma amounts for the years ended
        December 31, 1999 and 1998, and for the period from inception (July 14,
        1997) to December 31, 1999:

9.      Income Taxes

        The Company accounts for income taxes in accordance with SFAS No. 109,
        "Accounting for Income Taxes", ("SFAS 109"). SFAS 109 provides for an
        asset and liability approach to account for income taxes under which
        deferred tax assets and liabilities are recognized for the future tax
        consequences attributable to differences between the financial statement
        carrying amounts of existing assets and liabilities, and their
        respective tax bases. Deferred tax assets and liabilities are


<PAGE>   16

        measured using enacted tax rates expected to apply to taxable income in
        the years in which those temporary differences are expected to be
        recovered or settled. Deferred tax assets are reduced by a valuation
        allowance when, in the opinion of management, it is more likely than not
        that some or all portion of the deferred tax assets will not be
        recognized. The effect on deferred tax assets and liabilities of a
        change in tax rates is recognized in income in the period of enactment.

The net deferred income tax asset consists of the following:

</TABLE>

        Net operating loss carryforwards for Federal and state income tax
        purposes at December 31, 1999 and 1998, were approximately $5.3 million
        and $1.9 million, respectively. The net operating loss carryforwards
        expire on various dates through the year 2019. The Internal Revenue
        Service Code contains provisions which may limit the net operating
        losses and credit carryforwards to be used in any given year upon the
        occurrence of certain events, including a significant change in
        ownership interest. The Company believes significant uncertainty exists
        regarding the realizability of the net operating losses and credit
        carryforwards and other timing differences at December 31, 1999 and
        1998, and, accordingly, has provided a full valuation allowance.

        As of December 31, 1999 and 1998, respectively, the Company also had
        available research and development credits carryforwards of
        approximately $90,000 and $23,000 for Federal income tax purposes and
        $76,000 and $19,000 for state income tax purposes. The Federal research
        and development credits expire on various dates through the year 2019
        and the state research and development credits carryforward
        indefinitely.

10.     Related Party Transactions

        In July 1997, the Company entered into a contract with the Institute for
        Defense Education and Analysis ("IDEA") at the Naval Postgraduate School
        whereby the Company would develop certain web-based technology content
        for the IDEA. In October 1997, the Company entered into a subcontract
        agreement with one of its shareholders to provide the services under the
        contract. As of December 31, 1999, all services under the contract have
        been performed and all related revenue had been recognized.

11.     Subsequent Events

        In May 2000, in connection with a guaranty by Safeguard of the Loan, the
        Company issued warrants to purchase 390,909 shares of the Company's
        common stock at an exercise price of $0.94 per share. These warrants are
        exercisable beginning in May 2000 and expire in May 2005.

        In June 2000, the Company entered into a line of credit with Safeguard
        to provide for borrowings up to $1.6 million to be used for working
        capital purposes. Interest on this line accrues at prime plus 1 percent.
        All outstanding principal and accrued interest under this line of credit
        shall be due and payable upon the earlier of (i) September 30, 2000,
        (ii) an IPO or a private equity offering of at least $5 million, or
        (iii) the sale of substantially all of the Company's assets or shares of
        capital stock. Borrowings under this line of credit are secured by
        virtually all of the Company's assets. In connection with this line of
        credit agreement, the Company issued warrants to purchase 727,273


<PAGE>   17

        shares of the Company's common stock to Safeguard at an exercise price
        of $0.94 per share. These warrants are exercisable beginning in June
        2000 and expire in June 2005.

        In June 2000, the Company entered into a loan agreement with Safeguard
        to provide for borrowings up to $300,000 to be used for working capital
        purposes. Interest on this loan accrues at prime plus 1 percent. All
        outstanding principal and accrued interest under this loan shall be due
        and payable upon the earlier of (i) June 3, 2001, (ii) 60 days after the
        demand for payment by the lender, or (iii) upon the closing of a sale of
        substantially all of the Company's assets. In connection with this loan
        agreement, the Company issued warrants to purchase 136,364 shares of the
        Company's common stock to Safeguard at an exercise price of $0.94 per
        share. These warrants are exercisable beginning in June 2000 and expire
        in June 2005.

        In June 2000, the Company entered into a forbearance agreement in
        connection with violation of certain stipulations in its original Loan
        agreement dated December 1999. Under the amended terms of this
        agreement, the lender agreed to forbear any action against the Company
        for these violations until July 31, 2000. In consideration of this
        forbearance agreement, the Company issued warrants to purchase 148,936
        shares of the Company's common stock at an exercise price of $0.94 per
        share. These warrants are exercisable beginning in June 2000 and expire
        in June 2005.

        In July 2000, the Company amended its Note to allow Safeguard the right
        to convert any outstanding principal and accrued interest on the Note
        into fully-paid and non-assessable shares of the Company's common stock
        at a conversion price of $1.10 per share. The Company also amended the
        underlying warrant agreement on the Note to allow Safeguard to purchase
        from the Company up to 681,800 shares of the Company's common stock at a
        purchase price of $1.10 per share provided, however, that in the event
        of a merger of the Company with or into another entity prior to July 15,
        2001, the warrants shall be exercisable only for up to 340,900 shares of
        the Company's common stock. These warrants are in place of, and not in
        addition to, the warrants issued in the original agreement as discussed
        in Note 8.

        In July 2000, the Company entered into an agreement to be acquired by
        DigitalThink effective July 6, 2000. Under the terms of the agreement,
        each share of the Company's common stock and preferred stock will be
        converted into .0588 shares of DigitalThink's common stock. The
        transaction will be accounted for by DigitalThink using the purchase
        method. Subsequent to the acquisition, the Company will cease business
        operations on a stand-alone basis.

               UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION

Effective July 6, 2000, DigitalThink, Inc. ("DigitalThink" or the "Company")
acquired 100 percent of the outstanding stock and assumed all outstanding stock
options of Arista Knowledge Systems, Inc. ("Arista"), an emerging leader in
providing Internet-based learning management systems, in exchange for
approximately 746,000 shares of DigitalThink common stock. The total cost of the
acquisition, including transaction costs, was approximately $24.6 million. The
acquisition was accounted for as a purchase business combination.

Attached are the unaudited pro forma condensed financial statements, which
include the unaudited pro forma condensed balance sheet as of June 30, 2000 and
the unaudited pro forma condensed statements of operations of the Company and
Arista for the quarter ended June 30, 2000 and of the Company for the year ended
March 31, 2000, and Arista for the year ended December 31, 1999. The unaudited
pro forma condensed balance sheet assumes the acquisition took place on June 30,
2000. The unaudited pro forma condensed statements of operations, assume the
acquisition had been consummated on April 1, 1999. The unaudited pro forma
condensed financial information reflects the allocation of purchase price of
Arista based upon current estimates of fair values of assets acquired and
liabilities assumed. The final allocation of the purchase price may vary as
additional information is obtained and, accordingly, the ultimate allocation may
differ from that used in the unaudited pro forma condensed financial
information.

The unaudited pro forma condensed financial statements are based on the
historical financial statements of the Company and Arista. They are not
necessarily indicative of the combined entity's operations had the acquisition
actually occurred on the dates indicated, nor are they necessarily indicative of
future operations. The pro forma adjustments and the assumptions on which they
are based are described in the accompanying notes to these statements.

The unaudited pro forma condensed financial statements are based on and should
be read in conjunction with the historical consolidated financial statements and
related notes thereto of the Company for the year ended March 31, 2000 and the
quarter ended June 30, 2000 and the accompanying historical consolidated
financial statements and the notes thereto of Arista for the year ended December
31, 1999 and the six months ended June 30, 2000 and 1999.

3.  UNAUDITED PRO FORMA CONDENSED STATEMENTS OF OPERATIONS

    The accompanying unaudited pro forma condensed statements of operations have
    been prepared as if the acquisition was consummated as of April 1, 1999. Pro
    forma adjustments were made to reflect the:

    (d)  Amortization of acquired intangibles, with amortization periods of four
         years for amounts allocated to acquired technology, workforce and the
         excess of cost over fair value of net assets acquired.
    (e)  Amortization of deferred stock compensation, with an amortization
         period of up to four years representing the remaining vesting period of
         the options assumed using the multiple option amortization approach.

The accompanying unaudited pro forma condensed statements of operations do not
reflect the one-time impact of the charge for purchased in-process research and
development of $7.1 million recorded by the Company in connection with the
acquisition.

The unaudited pro forma condensed statements of operations for the year ended
March 31, 2000 combined the results of DigitalThink for the year ended March
31, 2000 with the results of Arista for the year ended December 31, 1999.
Accordingly, the presentation excluded the results of Arista for the quarter
ended March 31, 2000. Unaudited results of operations of Arista for the quarter
ended March 31, 2000 included zero revenues and net loss of $1.5 million.
