                        Report of Independent Auditors


Board of Directors
DataSage, Inc.


We have audited the consolidated balance sheets of DataSage, Inc. (the
"Company") as of December 31, 1999 and 1998, and the related consolidated
statements of operations, shareholders' deficit, and cash flows for the years
then ended. 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 consolidated financial position of DataSage, Inc. at
December 31, 1999 and 1998, and the consolidated results of their operations and
their cash flows for the years then ended in conformity with accounting
principles generally accepted in the United States.

                                DATASAGE, INC.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               December 31, 1999


1.   Nature of the Business and Financial Statement Presentation


DataSage, Inc. (the "Company") was incorporated as Cirrus Recognition Systems,
Inc. on April 11, 1994 in the Commonwealth of Massachusetts. Upon receiving its
first round of third party financing on June 12, 1997, the Company changed its
name to DataSage, Inc. The Company develops a high performance data mining
software product based on its proprietary pattern recognition technology.  The
Company has marketed its product initially to the retail industry.  The Company
has also licensed certain of its pattern recognition technology to other
software developers for various applications.  The Company's customers are
primarily within the U.S.


2.   Summary of Significant Accounting Policies

Cash Equivalents

Cash equivalents consist primarily of cash deposits and money market investments
with original maturities of 90 days or less when purchased.

Property and Equipment

Property and equipment are recorded at cost and depreciated using the straight-
line method over their estimated useful lives, which range from 3 to 7 years or,
in the case of leasehold improvements, over the shorter of their estimated
useful lives or the remaining life of the lease.  Depreciation expense was
approximately $188,000 and $94,000 for the years ended December 31, 1999 and
1998, respectively.

Financial Instruments

The Company's financial instruments, which include cash and cash equivalents,
accounts receivable, accounts payable, and accrued expenses, are carried at cost
which approximates fair market value at the balance sheet date. It is not
practicable to estimate the fair market value of notes payable to shareholders
as they are with related parties.

Consolidation

The Company consolidates its two wholly owned subsidiaries, DataSage Securities
Corporation and DataSage Acquisition Corporation.  All intercompany balances
have been eliminated in consolidation.

Revenue Recognition

The Company accounts for its software revenues in accordance with Statement of
Position ("SOP") 97-2, Software Revenue Recognition, as amended by SOP 98-4 and
SOP 98-9.  SOP 97-2 and SOP 98-4 were adopted effective January 1, 1998, and did
not have a material impact on the Company's financial results.  The Company does
not believe that the full adoption of SOP 98-9 effective January 1, 2000 will
have a material impact on the Company's financial condition and results of
operations.

The Company's revenues are derived primarily from license fees for its pattern
recognition technology, sales of software products including

                                       11
<PAGE>

software maintenance and post-contract customer support, and consulting
revenues. License fees and product sales are recognized when persuasive evidence
of an agreement exists, shipment of the product has occurred, no significant
vendor obligations remain, the fee is fixed and determinable and collection is
probable. Maintenance and post-contract support revenues are recognized ratably
over the contractual periods for which the services are provided. Revenues from
consulting contracts are recognized over the term of the contract using the
percentage-of-completion method of accounting. Such estimates of percentage
complete are periodically reviewed against the attainment of contractually
agreed-upon milestones. If the estimate of costs to be incurred on a contract
indicates a loss, such loss is provided for currently in its entirety.

Customer advances and billed amounts due from customers in excess of revenue
recognized are recorded as deferred revenue.

Stock-Based Compensation

Stock-based awards to employees are accounted for in accordance with Accounting
Principles Board Opinion No. 25 and related interpretations ("APB 25");
accordingly, no compensation expense is recorded for options awarded to
employees with exercise prices equal to or in excess of the stock's fair value
on the date of grant and where the number of shares and exercise price are
fixed. Additionally, the Company complies with the disclosure requirements of
SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123").


Software Development Costs

Costs incurred in the research and development of the Company's products are
expensed as incurred. Costs associated with the development of computer software
are expensed prior to the establishment of technological feasibility (as defined
by SFAS No. 86, "Accounting for the Costs of Computer Software to be Sold,
Leased or Otherwise Marketed") and capitalized thereafter when material to the
Company's financial position or results of operations.  As of and for the period
since inception through December 31, 1999, no software development costs have
been capitalized since costs eligible for capitalization under SFAS No. 86 were
insignificant.

Intangible Assets

Intangible assets consist of the excess of purchase price over net tangible
assets acquired. Intangible assets are being amortized using the straight-line
method over a three year period.

The Company periodically reviews the carrying amounts of property and equipment,
identifiable intangible assets and excess of cost over fair value of net assets
acquired both purchased in the normal course of business and acquired through
acquisition to determine whether current events or circumstances, as defined in
Financial Accounting Standards Board No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, warrant
adjustments to such carrying amounts by considering, among other things, the
future cash inflows expected to result from the use of the asset and its
eventual disposition less the future cash outflows expected to be necessary to
obtain those inflows.  At this time, future cash inflows exceed future cash
outflows;

                                       12
<PAGE>

thus, no impairment loss has been recognized. Management reviews the valuation
and amortization periods of excess of cost over fair value of net assets
acquired on a periodic basis, taking into consideration any events or
circumstances which might result in diminished fair value or revised useful
life. No events or circumstances have occurred to warrant a diminished fair
value or reduction in the useful life of excess of cost over fair value of net
assets acquired.

Income Taxes

Deferred tax assets and liabilities are determined based on the difference
between the financial statement and the tax basis of assets and liabilities
using currently enacted tax rates.  A valuation allowance against deferred tax
assets is recorded if, based upon the weight of available evidence, it is more
likely than not that some or all of the deferred tax assets will not be
realized.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements. Actual results could
differ from those estimates and such differences may be material to the
financial statements.

Comprehensive Income

Effective January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130
established new rules for the reporting and display of comprehensive income
(loss) and its components.  There was no comprehensive income (loss) items for
the years ended December 31, 1999 and 1998.

Internally Used Computer Software

The Company adopted SOP 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use ("SOP 98-1") during the year ended
December 31, 1999. SOP 98-1 requires that entities capitalize certain costs
related to internal-use software once certain criteria have been met.  Such
adoption of SOP 98-1 did not have a material impact on the Company's financial
condition or results of operations.


3.   Concentrations of Credit Risk and Significant Customers

Cash, cash equivalents and accounts receivable potentially expose the Company to
concentrations of credit risk, as defined by SFAS 105, "Disclosure of
Information about Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentrations of Credit Risk".  Excess cash is
primarily invested in money market funds of major financial institutions.  The
Company provides credit, in the normal course of business, to a number of
customers geographically dispersed throughout the U.S.  The Company performs
ongoing credit evaluations of its customers and maintains allowances for
potential credit losses.

6.   Convertible Debt

During 1999, the Company entered into a line of credit which allows for
borrowings up to $3,000,000 and is convertible into shares of the Company's
common stock.  At December 31, 1999, the Company had borrowed $1,000,000, such
amount is due in a balloon payment of principal and interest at maturity in
October 2003.  Interest is due periodically and accrues at an annual rate of
10%.  Interest expense recognized in 1999 and 1998 was approximately $16,700 and
$0, respectively.

The lender has the right to convert up to 25% of the aggregate principal amount
borrowed into fully paid and nonassessable shares of the Company's common stock.
The number of shares into which the debt is convertible is a function of the
qualified transaction price or $6.66 received in the Series C preferred stock
issuance.  This formula provides for a return to the holder of the convertible
debt of approximately $111,000 based on the borrowings outstanding.  The maximum
possible premium to holders of the convertible debt was recognized as a
beneficial conversion feature in 1999.  This beneficial conversion feature has
been recognized as interest expense in the statement of operations.  In
addition, the Company is permitted to convert 25% of the outstanding principal
amount owed under the note into shares of the Company's common stock upon a
qualified public offering.

7.   Income Taxes

As of December 31, 1999, the Company had federal net operating loss
carryforwards of approximately $8,108,000 and research and development credit
carryforwards of approximately $166,000.  The net operating loss and credit
carryforwards will expire beginning in 2012, if not utilized.

Utilization of the net operating losses and credit carryforwards may be subject
to a substantial limitation due to the "change in ownership" provisions of the
Internal Revenue Code of 1986.  The annual limitation may result in the
expiration of net operating losses and credit carryforwards before utilization.

From commencement through June 12, 1997, the Company had elected to be treated
as an S Corporation under Subchapter S of the Internal Revenue Code of 1986, as
amended.  As such, federal income taxes were the responsibility of the
individual shareholders.  Concurrent with the Company's preferred stock
issuance, the Company's Subchapter S status was terminated.  The immediate tax
effect of the termination of the S Corporation election was not material.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes.  Significant components
of the Company's deferred taxes as of December 31 are as follows:

</TABLE>

The Company has established a valuation allowance equal to the net deferred tax
assets due to uncertainties regarding the realization of deferred tax assets
based on the Company's lack of earnings history.  The valuation allowance
increased by approximately $1,818,000 in 1999.

The Company's provision for income taxes differs from the tax expense (benefit)
amount computed by applying the statutory federal income tax rate of 34% to
income before income taxes primarily as a result of the application of a
valuation allowance.

8.   Acquisition

On November 16, 1999 the Company acquired all of the outstanding stock of Online
Development Corporation ("ODC")in exchange for 741,300 newly issued shares of
the Company's common stock and cash of $430,000.  The acquisition was accounted
for using the purchase method of accounting, and accordingly, the results of
operations of ODC have been included in the consolidated results of operations
of the Company from the date of acquisition.  The total purchase price for ODC
was $7,977,000 based on the value of the shares of the Company's common stock
issued of $7,479,000, cash of $430,000 and related acquisition costs of $68,000.
The excess of purchase price over the tangible net liabilites acquired was
allocated to goodwill. This acquisition resulted in goodwill of approximately
$8,102,000.  Amortization expense for 1999 was approximately $335,000.

9.   Redeemable Convertible Preferred Stock

The Company is authorized to issue 15,000,000 shares of preferred stock. At
December 31, 1999, 3,469,233, 7,761,965, and 3,528,487 shares of Series A,
Series B, and Series C redeemable convertible preferred stock were issued and
outstanding, respectively.

The Series A, Series B, and Series C preferred stock has the following
characteristics:

Voting

Holders of preferred stock are entitled to the number of votes equal to the
number of common shares into which the shares of preferred stock are
convertible. The holders of preferred stock and common stock vote together as a
single class on all matters.

Dividends

Holders of preferred stock are entitled to receive, out of funds legally
available, dividends when and if declared by the Board of Directors, prior to
the payment of any dividends to the holders of the Company's common stock.
Through December 31, 1999, no dividends had been declared.

Liquidation Preference

The holders of preferred stock rank equally, up to their respective original
issue prices, with respect to any such distribution resulting from any
liquidation, dissolution or winding-up of the Company. If the assets of the
Company are insufficient to pay the holders of preferred stock the full amount
of the liquidation preference to which they are entitled, the holders of each
series of the preferred stock share ratably in any distribution of assets in
proportion to the original amount invested by each of the holders of the Series
A preferred stock, Series B preferred stock, and Series C preferred stock.

The holders of Series C preferred stock are entitled to receive, prior to and in
preference to the holders of common stock, a "Series C Preferred Liquidation
Amount" of $6.66 per share plus all declared and unpaid dividends.

                                       17
<PAGE>

The holders of Series B preferred stock are entitled to receive, prior to and in
preference to the holders of common stock, a "Series B Preferred Liquidation
Amount" of $0.90 per share, plus all declared and unpaid dividends.

The holders of Series A preferred stock are entitled to receive prior to and in
preference of the holders of common stock, the Series A original issue price of
$0.8125 per share. Following this payment and payment of the Series B Preferred
Liquidation Amount, the holders of Series A preferred stock and common stock
shall share ratably in the remaining assets of the Company until the holders of
Series A preferred stock receive an additional sum of $2.4375 per share, or an
aggregate total of $3.25 per share (the "Series A Preferred Liquidation
Amount"). If the amount payable to the Series A preferred shareholders exceeds
$3.25 per share under this calculation, the holders of Series A preferred stock
shall receive an amount per share as would be payable had each share of Series A
preferred stock been converted to common stock immediately prior to such event.

After the payments of the Series A Preferred Liquidation Amount and the Series B
Preferred Liquidation Amount have been made in full, holders of preferred stock
are not entitled to further participation in the distribution of the assets of
the Company. The remaining assets of the Company will be distributed ratably
among the holders of common stock.

Conversion

Each share of Series A, Series B, and Series C preferred stock may be converted,
at the option of the shareholder, into one share of common stock, subject to
adjustment for stock splits and certain anti-dilution provisions. The Series A,
Series B and Series C preferred stock is automatically converted into common
stock upon the closing of an initial public offering of the Company's common
stock or a qualified event.

At the issuance of the Series C preferred stock in December 1999, the deemed
fair value per share of the Company's common stock was greater than the price
per share of the Series C prefered stock paid by the Series C shareholders.
Accordingly, there is a beneficial conversion feature or discount on Series C
preferred stock in the amount of $68.0 million. However, the amount recorded is
limited to the proceeds received, or $23.5 million. Such beneficial conversion
feature or discount was immediatley accreted or recognized as a preferred stock
dividend as the Series C preferred stock was convertible immediately.

Redemption

Commencing at any time on or after June 1, 2003, subject to written election of
the holders of at least 60% of the outstanding shares of Series A, Series B, and
Series C preferred stock, the Company shall redeem the then-outstanding shares
in equal annual installments over a three-year period at the respective original
issue price per share (adjusted for stock splits and certain anti-dilution
provisions) plus any declared but unpaid dividends.


10. Shareholders' Deficit

                                       18
<PAGE>

Common Stock

Each share of common stock entitles the holder to one vote on all matters
submitted to a vote of the Company's shareholders. Common shareholders are
entitled to receive dividends, if any, as may be declared by the Board of
Directors, subject to the preferential dividend rights of the Series A, Series
B, and Series C preferred shareholders.


Restricted Stock Agreement and Note Receivable for Purchase of Common Stock

The Company has entered into a stock restriction agreement with an officer of
the Company for the purchase of 725,000 shares of common stock. The agreement
provides that, in the event the Company no longer employs this individual, the
Company has the right to repurchase any or all unvested shares at their original
issue price. These restrictions lapse 20% on the first anniversary of the note,
November 16, 1999, and the remaining ratably quarterly over the remaining four-
year period. Of these restricted common shares, 145,000 vested in November 1999
and 36,250 shares vest quarterly thereafter. At December 31, 1999, 580,000
shares of common stock were subject to repurchase by the Company.

In December 1998, the Company extended a loan to an officer of the Company in
the amount of $65,250 with interest payable at 4.52% per annum. The note was
used to finance the purchase of 725,000 shares of the restricted common stock
and is collateralized by those shares. The principal balance of the note plus
all accrued but unpaid interest is due in December 2003. During 1999, $13,100
was repaid. The common stock purchased by the officer is being accounted for as
a variable grant. The Company recorded stock compensation expense of
approximately $2.9 million related to the shares which vested on the first
anniversary date. The amount recorded as stock compensation expense for the
vested shares represents the difference between the purchase price and the
deemed fair value of the Company's common stock at the vesting date, November
16, 1999. The Company recorded deferred stock compensation of approximately
$11.6 million related to unvested shares at December 31, 1999. The amount
recorded as deferred stock compensation for the unvested shares represents the
difference between the purchase price and the deemed fair value of the Company's
common stock at December 31, 1999.

Treasury Stock

Concurrent with the Series A preferred stock financing in June 1997, the Company
repurchased 300,000 shares of common stock from the Company's founder at a
purchase price of $0.05 per share. Such treasury stock has been recorded at
cost.

Stock Option Plans

In November 1996, the Company adopted the 1996 Stock Option Plan, which provided
for the grant of incentive stock options and non-qualified options for the
purchase of up to 600,000 shares of the Company's common stock.

The incentive stock options may be granted to employees of the Company and the
non-qualified Options may be granted to employees, non-employee directors and
consultants as authorized by the Board of Directors.

                                       19
<PAGE>

In June 1997, the Company adopted the 1997 Stock Option Plan (the "Plan"),
Concurrent with the Series B preferred stock financing in October 1998, the
Board amended the Plan to increase the number of options available for the
purchase of shares of the Company's common stock to 3,560,000.  On December 9,
1999 the Company's board of directors amended the Plan to increase the number of
options available for the purchase of shares under the plan to 3,937,000.  The
total option pool includes 348,000 incentive stock options, which were granted
through June 1997 under the 1996 Stock Option Plan. The Board determines the
term of each option, the option exercise price, the number of shares for which
each option is granted and the rate at which each option is exercisable.
Incentive stock options may be granted to any employee at an exercise price per
share of not less than the fair value of the common stock of the date of the
grant (110% of the fair value for shareholders who hold greater than 10% of the
combined classes of stock) and with a term not to exceed ten years from the date
of the grant (five years for greater than 10% shareholders).

For purposes of pro forma disclosure, the fair value of each option grant was
estimated on the date of grant using the minimum value option pricing model with
the following assumptions for grants in 1999 and 1998: no dividend yield; near
zero volatility; risk-free interest rates ranging from 4.23% to 6.28%; and
expected lives of 5 years.

The effect of applying SFAS 123 to the Company's stock option awards did not
result in pro forma net loss that was materially different from historical
amounts, reported. Therefore, such pro forma information is not separately
presented herein. Future pro forma net income (loss) results may be materially
different from actual amounts reported.

A summary of the status of stock options granted under the Plan as of
December 31, 1999 and 1998 and changes during the years then ended are presented
below:

</TABLE>

There were 823,454 and 402,351 options exercisable as of December 31, 1999 and
1998, respectively.

Options granted by the Company generally vest ratably over 5 years and expire in
10 years.

At December 31, 1999, the Company has reserved 3,099,070 shares of common stock
for the future exercise of stock options, and has 201,970 options available for
grant.

Deferred Stock Compensation

In 1999, the Company granted 9,000 options to certain non-employees which vested
immediately. In connection with such grants, the Company recognized stock
compensation expense of $26,000 based on the Black-Scholes pricing model, using
a volatility factor of 50%, a risk-free interest rate of 5.70%, a dividend yield
of -0-%, and an expected life of 1 year.

In 1998, the Company granted 10,000 options to certain non-employees which vest
ratably over 2 years. In connection with the vesting of 5,000 and 1,250 options
in 1999 and 1998 respectively, the Company recorded stock compensation expense
of approximately $43,000 an $0 in 1999 and 1998, respectively.  At December 31,
1999 the Company recorded deferred stock compensation of approximately $75,000
related to the 3,750 unvested options.  The amounts recorded were based on the
Black-Scholes pricing model, using a volatility factor of 50%, a risk-free
interest rate of 5.70%, a dividend yield of -0-%, and an expected life of 1
year.

The Company recorded deferred stock compensation of approximately $18.8 million
in 1999.  The amount recorded represents the difference between the grant price
and the deemed fair value of the Company's common stock for shares subject to
options granted in 1999.  A total of 1,542,500 shares were granted below deemed
fair value and the exercise prices and deemed fair values ranged from $0.09 to
$6.00 per share and $0.40 to $20.18 per share, respectively.  The deferred stock
compensation is amortized over the vesting period of each respective option,
generally five years.  Approximately $504,000 was recorded as compensation
expense in 1999.

The Company has also granted the right to an employee to purchase up to 25,000
shares of common stock, dependent upon certain future events.  Such options, if
vested, will have an exercise price per share equal to the fair value of the
Company's common stock on the date which events occur, and will be exercisable
over a five year period.

11. Commitments

The Company leases its office space and certain office equipment under
noncancelable operating leases. Total rent expense under these operating leases
was approximately $241,000 and $136,000, for the years ended December 31, 1999
and 1998, respectively.

In December 1997, the Company obtained a commitment from a lessor to establish
lease agreements under which the Company may borrow up to $700,000 to finance
property and equipment purchases. The initial term of each borrowing under the
line of credit is 36 months from the borrowing date, with payments made monthly,
including interest at approximately 20% per annum. At the end of the term of
each borrowing, the Company has the option to extend the borrowing for an
additional five months at the same monthly payment, or pay a lump sum amount
equal to 15% of the original purchase price of the assets; otherwise, the assets
revert to the lender. All borrowings under the lease agreements are
collateralized by the fixed assets acquired.  At December 31, 1999, $515,000 has
been borrowed and $185,500 remained available under this lease committment.


Future minimum lease commitments at December 31, 1999 are as follows:

              UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION

Effective February 15, 2000, Vignette Corporation ("Vignette" or the "Company")
acquired 100 percent of the outstanding stock and assumed all outstanding stock
options of DataSage, Inc. ("DataSage"), a leading provider of e-marketing and
personalization applications that help organizations create a single enterprise-
wide view of their customers, in exchange for approximately 3.16 million shares
of Vignette common stock. The total cost of the acquisition, including
transaction costs, was approximately $586.5 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 December 31, 1999
and the unaudited pro forma condensed statement of operations of the Company and
DataSage for the year ended December 31, 1999, and related notes thereto. The
unaudited pro forma condensed balance sheet assumes the acquisition had been
consummated on December 31, 1999.  The unaudited pro forma condensed statement
of operations, including the weighted average number of shares used in the
calculation of the pro forma per share data, assume the acquisition had been
consummated on January 1, 1999. The unaudited pro forma condensed financial
information reflects the allocation of the purchase price of DataSage based upon
current estimates of the 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 DataSage.  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 and the historical consolidated financial
statements and notes thereto of DataSage for the year ended December 31, 1999.
