(b) Unaudited Interim Financial Information

The accompanying unaudited condensed consolidated financial statements have been prepared by Insightful pursuant to accounting
principles generally accepted in the United States and the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by
generally accepted accounting principles for complete financial statements. The balance sheet at December 31, 2005 has been derived from audited financial statements at that date, but does not include all disclosures required by generally
accepted accounting principles for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2005
included in Insightfuls Annual Report on Form 10-KSB. The accompanying condensed consolidated financial statements reflect all adjustments (consisting solely of normal, recurring adjustments), which, in the opinion of management, are necessary
for a fair presentation of results for the interim periods presented. The results of operations for the three months ended March 31, 2006 are not necessarily indicative of the results to be expected for the entire fiscal year or future years.

Revenue Recognition

Insightful offers a variety of scalable data analysis software solutions, maintenance contracts, training and
consulting services to its customers. Insightful records revenue in accordance with Statement of Position No. 97-2 (SOP 97-2), Software Revenue Recognition, as amended by SOP No. 98-9,

Software Revenue Recognition, with Respect to Certain Transactions, as well as related interpretations including Technical Practice Aids.

Software license revenues consist principally of fees generated from granting rights to use Insightfuls software products under
perpetual and fixed-term license agreements. The Company also refers to fixed-term license agreements as subscription-based license agreements.

Perpetual software license fees are generally recognized upon delivery of the software after receipt of a definitive purchase order, if collection of the resulting receivable is probable, the fee is fixed or determinable, and
vendor-specific objective evidence (VSOE) of fair value exists for all undelivered elements if sold in a bundled arrangement. VSOE is based on the price charged when an element is sold separately or, in case of an element not yet sold
separately, the price established by authorized management, if it is probable that the price, once established, will not change before separate introduction into the marketplace.

Revenues under arrangements that include several different software products and services sold together are allocated based on the residual method in
accordance with SOP No. 98-9. Under the residual method, the fair value, as determined by VSOE, of the undelivered non-essential elements is deferred and subsequently recognized when earned.

Insightful has established VSOE of fair value for professional services and training services. In addition, the Company has established VSOE for
maintenance related to most of its products. For software products sold with maintenance where VSOE for the maintenance element has not been established, such as InFact, all revenue under the arrangement is recognized over the initial maintenance
term, provided all other revenue recognition criteria have been met.

Maintenance revenue is recognized ratably over the term of the
related maintenance contracts, which generally span one year or less. The initial one-year maintenance contract is bundled into the license fees on most of the Companys products. Maintenance services, which include unspecified product upgrades
on a when-and-if available basis, are generally priced based on a percentage of the current list price of the licensed software products. Maintenance renewals are optional.

Consulting revenues typically include providing customers assistance in developing complex software models or data and text analysis techniques. In
addition, they include deployment assistance, project management, integration with existing customer applications and related services performed on a time-and-materials basis under separate service arrangements. Training consists of fee based
courses offered on a per-attendee or a per-group rate. Revenues from consulting and training services are generally recognized as services are performed.

Fees from licenses sold together with consulting are generally recognized upon shipment of the software, provided that the above residual method criteria are met, payment of the license fees are not dependent upon the
performance of the services, and the consulting services are not essential to the functionality of the licensed software. If the services are essential to the functionality of the software, or payment of the license fees is dependent upon the
performance of the services, both the software license and consulting fees are recognized under the percentage of completion method of contract accounting.

If the fee is not fixed or determinable, revenue is recognized as payments become due from the customer. If an acceptance period is required, revenues are recognized upon the earlier of customer acceptance or the
expiration of the acceptance period. An evaluation on the probability of collection is generally based upon the assessment of the customers financial condition. For existing customers, this evaluation leverages a customers prior payment
history. Insightful has an unconditional 30-day return policy on software license purchases, and therefore provides for estimated returns at the time of sale based on historical experience.

(c) Stock-Based Compensation and Stockholders equity

Stock-Based Compensation Expense

On January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, (SFAS 123(R)) which requires the measurement and
recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options and employee stock purchases related to the Employee Stock Purchase Plan (employee stock purchases)
based on estimated fair values. SFAS 123(R) supersedes the Companys previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25) for periods beginning in
fiscal 2006. In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 (SAB 107) relating to SFAS 123(R). The Company has applied the provisions of SAB 107 in its adoption of SFAS 123(R).

The Company adopted SFAS 123(R) using the modified prospective transition method, which requires the application of the accounting
standard as of January 1, 2006, the first day of the Companys fiscal year 2006. The Companys Consolidated Financial Statements as of and for the three months ended March 31, 2006 reflect the impact of SFAS 123(R). In accordance
with the modified prospective transition method, the Companys Consolidated Financial Statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123(R). Stock-based compensation expense recognized
under SFAS 123(R) for the three months ended March 31, 2006 was $0.2 million, which consisted of stock-based compensation expense related to employee stock options and the employee stock purchase plan. There was no stock-based compensation
expense related to employee stock options and the employee stock purchase plan recognized during the three months ended March 31, 2005.

SFAS 123(R) requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense
over the requisite service periods in the Companys Consolidated Statement of Operations. Prior to the adoption of SFAS 123(R), the Company accounted for stock-based awards to employees and directors using the intrinsic value method in
accordance with APB 25 as allowed under Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123). Under the intrinsic value method, no stock-based compensation expense had
been recognized in the Companys Consolidated Statement of Operations because the exercise price of the Companys stock options granted to employees and directors equaled the fair market value of the underlying stock at the date of grant.

Stock-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is
ultimately expected to vest during the period. Stock-based compensation expense recognized in the Companys Consolidated Statement of Operations for the first quarter of fiscal 2006 includes compensation expense for share-based payment awards
granted prior to, but not yet vested as of December 31, 2005 based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS 123 and compensation expense for the share-based payment awards granted subsequent to
January 1, 2006 based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). The Company uses the straight-line single-option method to recognize the value of stock-based compensation expense for all
share-based payment awards. As stock-based compensation expense recognized in the Consolidated Statement of Operations for the first quarter of fiscal 2006 is based on awards ultimately expected to vest, it has been reduced for estimated
forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Companys pro forma information required under SFAS
123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred.

The weighted average fair value of employee stock options granted in the three months ended
March 31, 2006 and 2005 was $1.63 and $1.77, respectively.

SFAS 123(R) requires the disclosure of pro-forma information for periods
prior to its adoption. The following table illustrates the pro forma effect on net income and earnings per share for the three months ended March 31, 2005 if the Company had recognized compensation expense for all share-based payments to
employees based on their fair values under the provisions of SFAS 123:

Pro forma stock-based compensation amounts reported above reflect the correction of certain errors
discovered in the Companys 2005 stock option disclosures. These errors resulted in an overstatement of pro forma stock-based compensation disclosed in periods prior to the fourth quarter of 2005. The errors related to improper amortization of
Board of Director grants, as well as the use of inappropriate stock prices in 2002 and 2003 in the calculation of the volatility assumption used in the Black-Scholes pricing model that resulted in an overstatement of the volatility variable. This
resulted in an overstatement of stock-based compensation. These errors had the effect of overstating pro forma stock-based compensation reported for the three months ended March 31, 2005 by $0.3 million.

A reconciliation of pro forma stock-based compensation amounts reported for the three months ended March 31, 2005 in the March 31, 2005
financial statement footnotes to the restated amounts disclosed for the same period as of March 31, 2006 is as follows:

The weighted-average estimated fair value of employee stock options granted during the periods presented
below was estimated at the date of grant using the Black-Scholes option-pricing model, with the following weighted average assumptions:

|Expected life           |  | 3.75 years                  |   |  | 5.00 years |  
|Expected volatility     |  | 67.6                        | % |  | 84.0       | %

The risk-free interest rate used in the Black-Scholes valuation method is based on the implied
yield currently available in U.S. Treasury securities at maturity with an equivalent term. The Company has not declared or paid any dividends and does not currently expect to do so in the future. The expected term of options represents the period
that the Companys stock-based awards are expected to be outstanding and was determined based on historical weighted average holding periods and projected holding periods for the remaining unexercised shares. Consideration was given to the
contractual terms of the Companys stock-based awards, vesting schedules and expectations of future employee behavior. Expected volatility is based on the annualized daily historical volatility plus implied volatility of the Companys
stock price, including consideration of the implied volatility and market prices of traded options for comparable entities within its industry.

The variables used for stock price volatility and option lives involve managements best estimates, both of which impact the fair value of the option calculated under the Black-Scholes methodology and, ultimately, the expense that will
be recognized over the life of the option. SFAS No. 123R also requires that the Company recognize compensation expense for only the portion of options expected to vest. Therefore, the Company applied an estimated forfeiture rate that the
Company derived from historical employee termination behavior. If the actual number of forfeitures differs from the Companys estimates, additional adjustments to compensation expense may be required in future periods.

Stock compensation expense for options or warrants granted to non-employees has been determined in accordance with EITF Issue No. 96-18,
Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services, and is based on the fair value of the equity instruments issued.

Stockholders Equity and Stock Option Plans

Under the Companys 2001 Stock Option and Incentive Plan (the 2001 Plan), the Board of Directors may grant incentive stock options, nonqualified stock options, awards of common stock and
authorizations to make direct purchases of Insightfuls stock to eligible employees and others, as defined.

In 2002, the stockholders
approved an amendment to the 2001 Plan that allows for the automatic increase in the number of shares reserved for issuance of stock options under this plan on the first day of each fiscal year by the lesser of (a) 1,000,000 shares, (b) 7%
of the outstanding shares in the last day of the prior fiscal period, or (c) an amount determined by the board of directors. Accordingly, the company added 885,000 option shares to this plan on January 1, 2006, thereby bringing the total
options available for future grant under this Plan to 1,301,000 as of March 31, 2006. The options typically vest over various time-based milestones within a four-year period.

The Company has a 2001 Non-Employee Director Stock Option Plan (the 2001 Directors Plan) under which its non-employee directors receive
annual grants to purchase shares of Company common stock. All of the Companys option grants under the 2001 Directors Plan are made at or above fair market value at the time of grant. These options are fully vested upon grant. At
March 31, 2006, 651,000 options were available for future grant under the 2001 Directors Plan.

The Company also has a
Non-Qualified, Non-Officer Stock Option Plan (the 1996 Non-Officer Plan) under which employees and consultants to Insightful can be granted nonqualified options to purchase stock. The vesting of options granted under the 1996 Non-Officer Plan is
determined at the date of grant. Each option expires 10 years from the date of grant, subject to earlier termination if the optionee ceases to serve Insightful other than by reason of death or disability, and is not transferable. At March 31,
2006, 176,000 options were available for future grant under the 1996 Non-Officer Plan.

As of March 31, 2006, the total remaining unrecognized compensation cost related to unvested
stock options amounted to $1.6 million, which will be amortized over the weighted-average remaining requisite service period of 1.6 years.

(d) Cash Equivalents

Cash equivalents consist of highly liquid investments with original maturities of less than three
months at the time of purchase. Cash equivalents as of March 31, 2006, and December 31, 2005 included in Cash and Cash Equivalents amounted to $10.8 million and $9.2 million, respectively.

(e) Marketable Securities

The
Companys marketable securities are accounted for under the provisions of SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. Under SFAS 115, all of the Companys marketable securities are
defined as available-for-sale securities and, accordingly, they are accounted for at fair value with any unrealized gains and losses reported in stockholders equity as other comprehensive income. Realized net gains and losses on sales and
maturities of marketable securities are included in the consolidated statement of income as other income. Additionally, marketable securities having maturities of 90 days or less are classified as cash and cash equivalents, and those having
maturities greater than 90 days are classified as short-term investments. As of March 31, 2006, the companys total marketable securities were $6.7 million, of which $0.4 million were classified as short-term investments. As of
March 31, 2006, all marketable securities had a maturity of less than one year.

Of the total $6.7 million in marketable securities,
$6.1 million were corporate debt securities, $0.4 million were government and agency obligations, and $0.2 million were money market funds. As of March 31, 2006 there were approximately zero realized and unrealized gains and losses on
these investments.

During the first quarter 2006, the company received total gross proceeds of $5.4 million from the sale and maturities
of marketable securities a portion of which are classified in cash and cash equivalents,

##### Table of Contents

of which $5.2 million relates to corporate debt securities, and $0.2 million relates to government and agency obligations.

(f) Inventories

Inventories are
stated at the lower of cost (first-in, first-out) or market and consist principally of CDs and user manuals.

(g) Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Equipment and furniture is depreciated using
the straight-line method over estimated useful lives ranging from three to five years. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life.

(h) Research and Development

Insightful accounts for its software research and development costs in accordance with Statement of Financial Accounting Standards (SFAS) No. 86, Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise
Marketed. During the three months ended March 31, 2006, and 2005, the Company expensed all research and development costs, as those costs incurred from the date of technological feasibility (defined as a working model) to the
general release date, were not material.

(i) Funded Research

Insightful has a funded research group that receives funding from U.S. federal agencies for research work performed under government grants. Research
projects are focused primarily on extending the frontiers of data analysis for numeric, textual signal and image data. Research projects are primarily performed under cost reimbursement arrangements, which typically provide funding on a
time-and-materials basis based on agency-approved labor, overhead and profit rates. In some cases, grant contracts are structured on a fixed fee (payment) basis. Grant contracts generally require the submission of periodic progress and final finding
reports. Funding is generally received through cash requests or installment payments. Grant fees are generally recognized as the work is performed, and / or the fees become billable. Because the grants received are generally aligned with the
companys existing research activities, commercial initiatives, and product lines, the amounts earned from grants are recorded as an offset against total research and development costs. Receivables resulting from this activity are included in
other receivables on the balance sheets. Funding received under these grants is subject to audits for several years after the funding is received, and, depending on the results of those audits, the Company could be obligated to repay a portion of
the funding. A liability for such potential repayment has not been recorded as the Company considers it neither probable nor reasonably estimable.

(j) Foreign Currency Translation

The functional currency of the Companys foreign subsidiaries is the local currency
in the country in which the subsidiary is located. Assets and liabilities of foreign locations are translated to U.S. dollars using the exchange rate at each balance sheet date. Income and expense accounts are translated using an average rate of
exchange during the period. Foreign currency translation adjustments are accumulated as a separate component of stockholders equity. The Company is subject to transaction gains and losses from period to period due to exchange rate
fluctuations. The effect of aggregate transaction gains and losses is included in other income. The aggregate transaction gain (loss) was approximately $21,000 and ($116,000) for the 3 months ended March 31, 2006 and 2005, respectively.

(k) Goodwill and Other Long-Lived Assets

Goodwill represents the excess of the purchase price over the fair value of net assets obtained in business acquisitions accounted for under the purchase method of accounting. Insightful currently distinguishes three
reporting units that have goodwill, as follows: US Data Analysis, Insightful United Kingdom, and Insightful Switzerland.



- 12 -



---

##### Table of Contents

In accordance with SFAS 142, Goodwill and Other Intangible Assets, goodwill and other indefinite
lived intangibles are tested for impairment at least annually and written down and charged to results of operations only in periods in which the recorded value of those assets exceeds their fair value. SFAS 142 prescribes the use of the two-phase
approach for testing goodwill for impairment. The first phase is a screen for potential impairment, while the second phase (if necessary) measures the amount of impairment, if any. Current technology and other separable intangible assets that do not
have indefinite lives are continued to be amortized over their useful lives.

Insightful performs an annual goodwill impairment test, with
additional tests performed when events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. No impairment existed upon performing the annual impairment test in October
2005, nor did any such events occur or circumstances exist during the three months ended March 31, 2006 that would indicate impairment existed as of March 31, 2006.

(l) Long-Lived Assets

Other
intangibles with definite lives are stated at cost less accumulated amortization and are amortized on a straight-line basis over a time frame that approximates the pattern in which the economic benefits of the intangible asset are consumed. As of
March 31, 2006, the Companys Purchased Technology meets this classification and is being amortized to expense over 3 years.

In
accordance with SFAS No. 144, Accounting for Impairment or Disposal of Long-Lived Assets, the Company considers the existence of facts or circumstances, both internal and external that may suggest that the carrying amount of
long-lived assets may not be recoverable. If there were such facts and circumstances, recoverability of assets held and used would be measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to
be generated by the asset. If the carrying amount were higher, the impairment loss would be measured by the amount, if any, by which the carrying amount of the assets exceeds their fair value based on the present value of estimated expected future
cash flows.

(m) Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts
reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates used in preparing the financial statements relate to areas such as (i) revenue recognition,
(ii) provision for bad debt, (iii) useful lives for property and equipment and intangibles, (iv) fair values and impairment analysis of goodwill and intangible assets with definite lives, (v) tax assets and liabilities and
(vi) valuation of stock options using the Black Scholes option pricing model.

(n) Financial Instruments

At March 31, 2006, Insightful had the following financial instruments: cash and cash equivalents, short-term investments, accounts receivable, other
receivables, accounts payable, accrued liabilities, and equipment financing debt. The carrying value of cash and cash equivalents, short-term investments, receivables, payables and accrued liabilities approximates fair value based on the liquidity
of these financial instruments or based on their short-term nature. The carrying value of equipment financing debt approximates fair value based on the market interest rates available to the Company for debt of similar risk and maturities.

(o) Taxes

The
Company follows the asset and liability method of accounting for income taxes as set forth by SFAS No. 109, Accounting for Income Taxes, and the provisions of SFAS No. 5 Accounting for Contingencies. Under these rules, certain assumptions
are made which represent significant estimates. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their
respective tax basis,



- 13 -



---

##### Table of Contents

net operating loss and tax credit carryforwards, and tax contingencies. Deferred tax assets and liabilities are 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.

The Company is required
to estimate its potential tax obligations and claims in each of the jurisdictions in which it operates as part of the process of preparing its consolidated financial statements. Significant judgment is required in evaluating its tax positions and in
determining its provision for income taxes and accruals for income and other tax exposures. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. If necessary, the
Company establishes accruals for tax-related uncertainties based on estimates of whether, and to the extent which, additional taxes and interest will be due. These accruals would be established when, despite the Companys belief that its tax
return positions are fully supportable, the Company believes that certain positions are likely to be challenged and may not be sustained on review by tax authorities. These accruals would be adjusted in light of changing facts and circumstances,
such as the closing of a tax audit or the expiration of a statute of limitations. The Company has established a valuation allowance to reduce deferred tax assets as the Company believes it is not more likely than not that it will generate sufficient
taxable income to allow for the realization of its deferred net tax assets in the foreseeable future. The provision for income taxes includes the impact of potential tax claims and changes to accruals and valuation allowances that the Company
considers appropriate, as well as the related interest expense. In addition to the Companys judgments and use of estimates, there are inherent uncertainties surrounding taxes that could result in actual amounts that differ materially from the
Companys estimates. Any changes in circumstances related to these contingencies could have a material effect on the Companys financial condition, results of operations and cash flows.

(p) Recent Accounting Pronouncements

In November 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) Nos. FAS 115-1 and FAS 124-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments. FSP Nos. FAS 115-1
and FAS 124-1 amend SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, SFAS No. 124, Accounting for Certain Investments Held by Not-for-Profit Organizations, as well as APB Opinion No. 18, The Equity
Method of Accounting for Investments in Common Stock. This guidance nullifies certain requirements of EITF 03-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments. FSP Nos. FAS 115-1 and FAS 124-1 include
guidance for evaluating and recording impairment losses on debt and equity investments, as well as new disclosure requirements for investments that are deemed to not be other-than-temporarily impaired. FSP Nos. FAS 115-1 and FAS 124-1 also require
other-than-temporary impaired debt securities to be written down to their impaired value, which becomes the new cost basis. FSP Nos. FAS 115-1 and FAS 124-1 are effective for fiscal periods beginning after December 15, 2005 and are required to
be adopted by the Company in the second quarter of fiscal 2006. Although the Company will continue to evaluate the application of FSP Nos. FAS 115-1 and FAS 124-1, the Company does not currently believe adoption will have a material impact on its
results of operations or financial position.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections, a
replacement of APB Opinion No. 20 and SFAS Statement No. 3. SFAS No. 154 replaces APB Opinion No. 20, Accounting Changes, and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements, and changes the
requirements for the accounting for and reporting of a change in accounting principle. This statement applies to all voluntary changes in accounting principle. It also applies to changes required by an accounting pronouncement in the unusual
instance that the pronouncement does not include specific transition provisions. When a pronouncement includes specific transition provisions, those provisions should be followed. Opinion 20 previously required that most voluntary changes in
accounting principle be recognized by including in net income of the period of the change the cumulative effect of changing to the new accounting principle. This statement requires retrospective application to prior periods financial
statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that a change in depreciation, amortization, or
depletion method for long-lived, non-financial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. This statement carries forward without changing the guidance contained in Opinion 20 for
reporting the correction of an error in

##### Table of Contents

previously issued financial statements and a change in accounting estimate. This statement also carries forward the guidance in Opinion 20 requiring
justification of a change in accounting principle on the basis of preferability. The provisions of SFAS No. 154 are effective for accounting changes made in fiscal years beginning after December 15, 2005. The adoption did not have a
material impact on the Companys results of operations or financial position.

On January 1, 2006 the Company adopted SFAS 123R
Accounting for Share Based Payments, see footnote 2c.

(3) PURCHASED TECHNOLOGY

In January 2004, the Company acquired title to the software code underlying the S programming language from Lucent Technologies Inc. for $2.0
million. The $2.0 million purchase price included settlement in full for all royalties owed by the Company to Lucent at the date of the acquisition in the amount of $235,000. As a result of this transaction, $1,765,000 was capitalized as purchased
technology. This amount is being amortized to software related cost of revenues over a 3-year estimated life. The Company recognized $588,000 and $539,000 in amortization expense related to this technology during 2005 and 2004, respectively. The
Company recorded $147,000 in amortization expense related to this technology during the three months ended March 31, 2006 and 2005. This technology is scheduled to be fully amortized by January 31, 2007 with corresponding amortization
estimated to be $588,000 and $49,000 for 2006 and 2007, respectively.

Under the agreement, $1.5 million of the purchase price was paid in
the first quarter of 2004 and the remaining $0.5 million was paid in the first quarter of 2005.

Prior to this agreement, Insightful was a
worldwide licensee of the S programming language from Lucent Technologies Inc. Under that license, the Company had the right to use, sublicense and support the S language in exchange for royalties, with a minimum annual
exclusivity fee of $450,000 and variable royalties of 3% to 6% of revenues.

(4) FINANCING ARRANGEMENTS

In March 2006, the Company renewed a working capital revolving line of credit and security agreement with Silicon Valley Bank. The terms provide for up to
$3.0 million in borrowing availability through March 31, 2007. This facility is secured by the Companys accounts receivable and allows it to borrow up to the lesser of 75% of its eligible accounts receivable or $3.0 million and bears
interest at the prime rate plus 1%. At March 31, 2006, the prime rate was 7.75%, and no amounts had been borrowed under the line of credit facility.

The Company also had an outstanding balance on an equipment loan with Silicon Valley Bank, secured by underlying assets. The Company originally borrowed $450,000 under this facility in 2002. The Company entered the
first quarter of 2006 with a $32,000 outstanding balance, which was fully paid as of March 31, 2006. This loan called for interest equal to prime rate plus 1%, and was repaid over a 42-month period, ending in March 2006.

These credit facilities contain covenants that limit the Companys net losses and restricts the amount of capital expenditures not financed through
the equipment term loan. In addition, the Company is prohibited under these facilities from paying dividends. The Company was in compliance with these covenants as of March 31, 2006.

Future maturities of debt as of March 31, 2006 were zero.

|1 | For the three-month period ended March 31, 2006, Common stock equivalents totaled 654,000 and were excluded from dilutive net income (loss) per share, as their
inclusion would have been anti-dilutive.
|- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The dilutive impact of the Companys stock options is calculated using the
treasury stock method, based on the average share price of the Companys common stock. Under the treasury stock method, the proceeds that would be hypothetically received from the exercise of all stock options with exercise prices below the
average share price of the Companys common stock are assumed to be used to repurchase shares of the Companys common stock.

The
Company excludes all potentially dilutive securities from its diluted net income per share computation when their effect would be anti-dilutive. The following common stock equivalents were excluded from the earnings per share computation because the
exercise prices of the stock options and rights were greater than or equal to the average price of the common shares, and therefore their inclusion would have been anti-dilutive (in thousands):

(6) OTHER COMPREHENSIVE INCOME (LOSS)

SFAS No. 130,  Reporting Comprehensive Income, establishes standards for reporting and display of comprehensive income and its
components in the financial statements. As of March 31, 2006, comprehensive income (loss) included foreign currency translation adjustments. Total comprehensive income (loss) is as follows (in thousands):

also establishes standards for related disclosures about products, services, geographical areas and major customers. Business segment information includes
the segments of North American Data Analysis, International Data Analysis and Text Analysis. The Company measures segment performance based on their revenues and contribution margin, which is a measure of profitability that allocates only direct and
controllable costs to a segment. Depreciation expense is not allocated by segment. Assets are not allocated to segments for internal reporting presentations. Intercompany transactions have been eliminated from the segment information. Non-operating
income and expenses are not tracked by segment. Segment information is provided below (in thousands):

(9) REVENUE CONCENTRATION

No customer accounted for 10% or more of revenues for the three months ended March 31, 2006, and 2005.

(8) COMMITMENTS AND CONTINGENCIES

In certain of its licensing
agreements, the Company provides intellectual property infringement indemnifications. These indemnifications are excluded from the initial recognition and measurement requirements of FASB Interpretation No. 45, Guarantors Accounting
and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. The Companys policy is to record any obligation under such indemnification when a required payment under such indemnification is
probable and the amount of the future loss is estimable. At March 31, 2006, there were no such indemnifications for which a required payment was deemed to be probable or estimable; therefore, no accrual has been made for potential losses
associated with these indemnifications.

Our consulting and training organization provides fee-based services, including providing assistance in developing complex statistical models or data or text analysis techniques. These services also include deployment
assistance, project management, integration with existing customer applications and related services to our customers. We also offer a series of fee-based training courses to our customers. Courses can be taken at Insightfuls offices, at the
customers site, or at other prearranged sites for larger customer groups.

Critical Accounting Policies and Estimates

We have based our discussion and analysis of our financial condition and results of operations upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues
and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our critical accounting policies and estimates, including those related to revenue recognition, bad debts, intangible assets, restructuring,
and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect the more
significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

Our revenue recognition policy is significant because our revenues are a key component of our results of operations. We follow very specific and detailed
guidelines, discussed in Note 2 of the condensed consolidated financial statements, in measuring revenues.

We derive our revenues
primarily from three sources: license revenues, which consist of perpetual and fixed term software license fees, maintenance revenues, consisting of fees for maintenance and support, and professional services revenues, which are comprised of fees
for consulting and training. The revenue recognition rules for software companies are complex and require our management to exercise judgment and make a number of estimates. For example, many of our contracts contain multiple element arrangements,
which require us to make assumptions and judgments in order to allocate the total price



- 20 -

##### Table of Contents

among the various elements we must deliver, to determine whether vendor specific objective evidence of fair value exists for each element, to determine if
undelivered elements are deemed essential, and to determine whether and when each element has been delivered. We also evaluate whether there is any material risk of customer non-payment or product returns.

If we were to change any of these assumptions or judgments, which are made based upon all of the information available to us at the time, it could cause
a material increase or decrease in the amount of revenue that we report in a particular period. Deferred revenue is recognized over time as the applicable revenue recognition criteria are satisfied.

Stock-Based Compensation Expense

On
January 1, 2006, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, (SFAS 123(R)) which requires the measurement and recognition of compensation expense for all
share-based payment awards made to employees and directors including employee stock options and employee stock purchases related to the Employee Stock Purchase Plan (employee stock purchases) based on estimated fair values. SFAS 123(R)
supersedes our previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25) for periods beginning in fiscal 2005. In March 2005, the Securities and Exchange
Commission issued Staff Accounting Bulletin No. 107 (SAB 107) relating to SFAS 123(R). We have applied the provisions of SAB 107 in its adoption of SFAS 123(R).

We adopted SFAS 123(R) using the modified prospective transition method, which requires the application of the accounting standard as of January 1,
2006, the first day of our fiscal year 2006. Our Consolidated Financial Statements as of and for the three months ended March 31, 2006 reflect the impact of SFAS 123(R). In accordance with the modified prospective transition method, our
Consolidated Financial Statements for periods prior to the first quarter of 2006 have not been restated to reflect, and do not include, the impact of SFAS 123(R).

Under the provisions of SFAS No. 123(R), stock-based compensation cost is estimated at the grant date based on the fair-value of the award and is recognized as expense ratably over the requisite service period of
the award. Determining the appropriate fair-value model and calculating the fair value of stock-based awards at the grant date requires considerable judgment, including estimating stock price volatility, expected option life and forfeiture
rates. We develop our estimates based on historical data and market information, which can change significantly over time. A small change in the estimates used can have a relatively large change in the estimated valuation, and
consequently, a material effect of the results of operations.

The risk-free interest rate used in the Black-Scholes valuation method is
based on the implied yield currently available in U.S. Treasury securities at maturity with an equivalent term. We have not declared or paid any dividends and do not currently expect to do so in the future. The expected term of options represents
the period that our stock-based awards are expected to be outstanding and was determined based on historical weighted average holding periods and projected holding periods for the remaining unexercised shares. Consideration was given to the
contractual terms of our stock-based awards, vesting schedules and expectations of future employee behavior. Expected volatility is based on the annualized daily historical volatility plus implied volatility of our stock price, including
consideration of the implied volatility and market prices of traded options for comparable entities within our industry.

Our stock price
volatility and option lives involve managements best estimates, both of which impact the fair value of the option calculated under the Black-Scholes methodology and, ultimately, the expense that will be recognized over the life of the option.
SFAS No. 123R also requires that we recognize compensation expense for only the portion of options expected to vest. Therefore, we applied an estimated forfeiture rate that we derived from historical employee termination behavior. If the actual
number of forfeitures differs from our estimates, additional adjustments to compensation expense may be required in future periods.

##### Table of Contents

Stock-based compensation expense recognized under SFAS 123(R) for the three months ended March 31,
2006 was $0.2 million, which consisted of stock-based compensation expense related to employee stock options and employee stock purchases. There was no stock-based compensation expense related to employee stock options and employee stock purchases
recognized during the three months ended March 31, 2005. Had we recognized compensation expense for the three months ended March 31, 2005 for all share-based payments to employees based on their fair values, as is now required by SFAS
123(R), net income would have been lower by $0.2 million, or $0.02 per basic and diluted share.

As of March 31, 2006, the total
remaining unrecognized compensation cost related to unvested stock options amounted to $1.6 million, which will be amortized over the weighted-average remaining requisite service period of 1.6 years.

See Note 2 in the Consolidated Financial Statements for additional information on stock-based compensation expense and stock option related data.

Taxes

We follow the asset and
liability method of accounting for income taxes as set forth by SFAS No. 109, Accounting for Income Taxes, and the provisions of SFAS No. 5 Accounting for Contingencies. Under these rules, certain assumptions are made which represent
significant estimates. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis, net
operating loss and tax credit carryforwards, and tax contingencies. Deferred tax assets and liabilities are 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.

We are required to estimate our potential tax obligations and claims in each of the jurisdictions in which we
operates as part of the process of preparing our consolidated financial statements. Significant judgment is required in evaluating our tax positions and in determining our provision for income taxes and accruals for income and other tax exposures.
During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. If necessary, we establishe accruals for tax-related uncertainties based on estimates of whether, and to the
extent which, additional taxes and interest will be due. These accruals would be established when, despite our belief that our tax return positions are fully supportable, we believe that certain positions are likely to be challenged and may not be
sustained on review by tax authorities. These accruals would be adjusted in light of changing facts and circumstances, such as the closing of a tax audit or the expiration of a statute of limitations. We have established a valuation allowance to
reduce deferred tax assets as we believe it is not more likely than not that we will generate sufficient taxable income to allow for the realization of our deferred net tax assets in the foreseeable future. The provision for income taxes includes
the impact of potential tax claims and changes to accruals and valuation allowances that we consider appropriate, as well as the related interest expense. In addition to our judgments and use of estimates, there are inherent uncertainties
surrounding taxes that could result in actual amounts that differ materially from our estimates. Any changes in circumstances related to these contingencies could have a material effect on our financial condition, results of operations and cash
flows.

Sales Returns

We
provide an estimated reserve for return rights at the time of sale. We offer our customers a 30-day return policy on all of our products. Refunds are provided to customers upon return to us of the complete product package, including all original
materials, CD-ROM or other media. Our provision for sales returns is estimated based on historical returns experience and our judgment of the likelihood of future returns.

Bad Debts

A considerable amount of judgment is required when we assess the ultimate
realization of receivables, including assessing the aging of the amounts and reviewing the current creditworthiness of our



- 22 -

customers. Customer creditworthiness is subject to many business and finance risks facing each customer and is subject to sudden changes.

Impairment of Goodwill and Other Long Lived Assets

We evaluate goodwill arising from acquired businesses for potential impairment on an annual basis, during the fourth quarter. This evaluation requires significant judgment and estimation. In addition, throughout the year we consider whether
there are impairment indicators that would require an immediate evaluation of impairment. Our judgments regarding the existence of impairment indicators are based on legal factors, market conditions and operational performance of our acquired
businesses. Future events could cause us to conclude that impairment indicators exist and that goodwill associated with our acquired business is impaired.

Impairment losses, if any, will be charged to earnings in the period in which they are identified.

Contingencies

We are engaged in legal actions arising in the ordinary course of business. We are required to assess the likelihood of any adverse
judgments or outcomes to these matters as well as potential ranges of possible losses. A determination of the amount of reserves required, if any, for these contingencies are made after careful analysis of each individual matter. The required
reserves, if any, may change in the future due to new developments in each matter or changes in approach.

Software license revenue

Software license revenues consist principally of fees generated from granting rights to use our Data and Text Analysis software products under both perpetual and fixed-term (subscription) license agreements.

As compared to the corresponding period of 2005, Software license revenues decreased slightly for the three months ended March 31,
2006. This slight decrease was primarily due to the recognition in March 2005 of Text Analysis license revenue in the amount of $120,000 that related to a license sale booked in August of 2004. The revenue recognition for six months of this term
license was delayed until its unique acceptance criteria were met in March of 2005. Excluding this effect, license revenue increased slightly for the three months ended March 31, 2006, as compared to the corresponding period of 2005. This

adjusted increase was due to an increase in the average size of our larger Data Analysis license sales that began in 2005 (one of which totaled approximately
one million dollars in the quarter ended December 31, 2005), which, in part, is due and made possible by the release of S-Plus 7.0 Enterprise Server in April 2005, which was designed to process much larger data sets and address larger
statistical data analysis problems. This has allowed us to engage in larger sales opportunities and licensing arrangements.

Maintenance revenue

Software maintenance is generally included with the initial purchase of products under perpetual licenses, and the related revenue is
typically recognized as maintenance revenue ratably over the initial contractual maintenance period, which is generally one year following the initial license sale.

Software maintenance revenues increased by 13% for the three months ended March 31, 2006 as compared to the corresponding period of 2005. This increase was primarily due to the following factors:



| |  |  | An increase in our ongoing maintenance revenue stream driven by an increase in license revenues in 2005 and during the three months ended March 31, 2006 compared to the
corresponding prior year periods, as discussed above under Software license revenue. Higher license revenues drive an increase in our ongoing maintenance revenue stream because each Data Analysis license sale typically includes one year
of software maintenance that is amortized over a twelve-month period following the initial license sale.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in our overall pricing of our products and services that occurred in the beginning of the second quarter of 2005, and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | A slight increase in our overall renewal rates for our Data Analysis software maintenance.
| | - |  | ------------------------------------------------------------------------------------------

If we are unable to maintain our current level of renewals for our Data Analysis software maintenance, or sales of our Data Analysis software products,
our future maintenance revenue streams generated by our Data Analysis products may decrease.

Professional services and other revenue

Professional services and other revenue is generated from consulting and training activities. Professional services and other revenue increased by 16%
during the three-months ended March 31, 2006, as compared to the corresponding period in 2005, primarily resulting from one large European Data Analysis customer, who has continued to expand its use and deployment of our products and services.
Although we expect to continue to provide services to this customer for the remainder of 2006, such future services may, or may not, lead to an increase in our future professional services revenue.

Revenues by Segment

We review results from
three segments: North American Data Analysis, International Data Analysis, and Text Analysis and we have international business operations primarily in Europe, and sales activities in other parts of the world. Revenues by segment and geography are

North American Data Analysis revenue

North American Data Analysis revenues increased by 10% during the three months ended March 31, 2006, as compared to the corresponding period in 2005. The following factors predominantly drove this increase:



| |  |  | As discussed above under Software license revenue, we experienced an increase in the average size of our larger Data Analysis software sales during the three months
ended March 31, 2006, as compared to the corresponding period in 2005.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | As discussed above under Maintenance revenue, we experienced an increase in our North American Data Analysis maintenance revenue during the three months ended
March 31, 2006, as compared to the corresponding period in 2005.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We experienced a slight increase in our overall renewal rates for our Data Analysis software maintenance during these comparable periods.

International Data Analysis revenue

International
Data Analysis revenues increased by approximately $184,000 (or 10%) during the three months ended March 31, 2006, as compared to the corresponding period of 2005. This increase was primarily due to an increase in professional services revenue
of approximately $352,000 (or 82%), aided by an increase in maintenance revenue of approximately $45,000 (or 8%), and offset by a decrease in license revenues of approximately $213,000 (or 22%).

The increase in International professional services revenue is primarily attributable to revenues generated from the large European consulting customer
discussed previously. The increase in International maintenance revenue was due in large part to the increase in our International maintenance revenue stream, as discussed previously under Maintenance revenue above. The decrease in
international license sales during the three months ended March 31, 2006, as compared to the corresponding period of 2005 was due to a large above average sale that occurred in the quarter ended March 31, 2005, whereby the license sales in
the most recent quarter ended March 31, 2006 were generally smaller in size.

Text Analysis revenue

Text Analysis revenues decreased by approximately $183,000 (or 34%) for the three months ended March 31, 2006, as compared to the corresponding
period of 2005. This decrease was due to a decrease in Text Analysis professional services revenue of approximately $123,000 (or 68%), and to a smaller degree, by a decrease in Text Analysis license revenues of approximately $60,000 (or 17%).

The decrease in Text Analysis professional services revenue during the three months ended March 31, 2006, as compared to the
corresponding period of 2005, was primarily attributable to the completion of a large consulting engagement in the quarter ended March 31, 2005. Text Analysis consulting engagements serviced in the most recent quarter ended March 31, 2006
were all of a smaller size.

As compared to the corresponding period of 2005, Text Analysis license revenues decreased for the three months
ended March 31, 2006 due to the recognition of $150,000 in term license revenue that had been previously deferred due to revenue recognition requirements discussed above under Software License Revenue. Were it not for this, Text
Analysis license revenue would have increased for the three months ended March 31, 2006, as compared to the corresponding period of 2005.

Cost of software-related revenues consists of royalties for third-party software, product media, product duplication, manuals and maintenance and
technical support costs, and amortization of the costs of the software code underlying the S programming language purchased from Lucent Technologies Inc.

Although the cost of software-related revenue increased by 13% during the three months ended March 31, 2006, as compared to the corresponding period of 2005, the cost of software related revenues as a
percentage of software related revenues only increased by 1%, and this slight increase was due primarily to an increase in product and shipping costs.

Cost of software-related revenues fluctuates from period to period depending on the mix and level of revenues and depending on whether a particular quarter includes the cost of a license upgrade to existing
maintenance customers. Significant components of software-related costs of revenues are fixed, including amortization of the software code purchased from Lucent and costs associated with technical support.

Cost of professional services revenues

Cost of professional services and other revenues consist primarily of the following:



| |  |  | Direct headcount-related costs such as salaries and direct employee benefits,
| | - |  | -----------------------------------------------------------------------------



| |  |  | Indirect headcount-related costs such as recruiting fees, employee travel costs, office supplies, and headcount-based allocation of facilities, information technology, and human
resource costs, and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Temporary labor and consulting costs, including costs related to training.
| | - |  | --------------------------------------------------------------------------

Although the cost of professional services and other revenues increased by 19% during the three months ended March 31, 2006, as compared to the corresponding period of 2005, the cost of professional services
and other revenues as a percentage of professional services and other revenues increased by only 1%, and this slight increase was due primarily to an increase in professional services headcount in both the United States and Europe, including the
hiring of a Vice President of Professional Services in March 2006.

Cost of professional services and other revenues are predominantly made
up of headcount-related costs, which are relatively fixed in the short-term. Consequently, these costs as a percent of revenues, and gross margins, can fluctuate from quarter to quarter, and year to year, based primarily on the utilization

levels of our consultants and the profitability of our consulting contracts. Should our professional service revenues grow during the remainder of 2006, we
expect related growth in our costs of professional service revenues.

Sales and marketing expenses increased by approximately $289,000 (or 15%), and increased by 4% as a percentage of total revenues, during the three months ended March 31, 2006, as compared to the corresponding
period of 2005. These increases were due primarily to the increase in direct and indirect headcount-related costs resulting from the hiring of additional sales and marketing personnel in both the United States and Europe, including the hiring of our
Vice President of Marketing in the second quarter of 2005, and our General Manager of Text Analysis in the fourth quarter of 2005, as well as higher costs for temporary labor and promotional activities. Additionally, beginning January 1, 2006,
sales and marketing expenses reflect stock-based compensation expense related to employee stock options and employee stock purchases under SFAS 123(R), which amounted to $37,000 during the three-months ended March 31, 2006. Previously,
stock-based compensation expense was not included in our statement of operations.

We expect sales and marketing expenses to increase in
future periods as we recruit and hire additional personnel and expand our sales and marketing programs.

| |  |  | Temporary labor and consulting costs.
| | - |  | -------------------------------------

Further, research
and development is split into two teams: Research, and Development. Generally, the Research team is focused on performing work relating to government grants and contracts, whereas the Development team is generally focused on work that is geared
toward commercial applications that are intended to be immediately deployed. Funded research amounts result from fees generated from research work performed under government grants, which fees are netted against total research and development costs.

Gross research and development expenses

Gross research and development expenses increased by approximately $409,000, or 33%, and increased by 6% as a percentage of total revenues, during the three months ended March 31, 2006, as compared to the
corresponding period of 2005. These increases were due primarily to the increase in direct and indirect headcount-related costs resulting from the hiring of additional development personnel, as well as higher costs for temporary labor. Additionally,
beginning January 1, 2006, research and development expenses reflect stock-based compensation expense related to employee stock options and employee stock purchases under SFAS 123(R), which amounted to $23,000 during the three months ended
March 31, 2006. Previously, stock-based compensation expense was not included in our statement of operations.

We expect our combined
research and development expenses to increase in future periods as we place increased efforts toward further product development, while maintaining our current level of research efforts on government grants.

Funded research

Funded research
increased by approximately $53,000 (or 10%) and remained flat as a percentage of total revenues, during the three months ended March 31, 2006, as compared to the corresponding period of 2005. The dollar increase was due to higher billable
productivity from our billable research group.

Research and development, net

As a result of the increase in gross research and development costs outweighing the increase in the offsetting fees generated from funded research, total
net research and development costs increased during the three months ended March 31, 2006, as compared to the corresponding period of 2005.

During the remainder of 2006, we expect to increase our research and development expenses by investing in development of our product lines in order to set the foundation for future growth.

General and
administrative expenses increased by $15,000 (or 1%) and did not change as a percentage of total revenues, during the three months ended March 31, 2006, as compared to the corresponding period of 2005. The slight increase in dollars was
due primarily to the following offsetting factors:



| |  |  | Beginning January 1, 2006, general and administrative expenses reflect stock-based compensation expense related to employee stock options and employee stock purchases under
SFAS 123(R), which amounted to $101,000 during the three months ended March 31, 2006. Previously, stock-based compensation expense was not included in the statement of operations.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Bad debt expense decreased by approximately $108,000 driven by a reduction in our allowance for doubtful accounts resulting from a significant reduction in our accounts receivable
balance at March 31, 2006, and an improvement in our aging as compared to the corresponding period of 2005, and

Currently, we will be required to comply with of section 404 of the Sarbanes-Oxley as of December 31, 2007, however,
regulators are discussing potential changes to the current rules and regulations under Sarbanes-Oxley for non-accelerated and small-business filers, which may delay or remove the requirements currently in place. If we are required to comply, we do
not know what the level of expenditure will be, though it is expected to be material to our operations. If we are required to comply in 2007, we will incur related expenses in 2006.

In general, we expect to incur expenses in connection with our efforts to enhance our information technology resources and improve our financial and
managerial systems. Because some of these costs are allocated to the income statement expense line items based on headcount, all the expense line items in the statement of income will be affected by some of these added costs.

Interest income

The increase in interest income for the three months ended March 31, 2006, as compared to the corresponding period of 2005, was a result of both increased invested cash balances and the investment of a
greater portion of our cash reserves into higher yielding instruments.

Interest expense

The decrease in interest expense for the three months ended March 31, 2006, as compared to the corresponding period of 2005, was due to the
reduction in the outstanding balance of our equipment loan with Silicon Valley Bank, which was fully paid as of March 31, 2006.

Foreign exchange
transaction gains (losses)

Foreign exchange transaction gains and losses result from changes in exchange rates on transactions
denominated and or settled in currencies other than that of an entitys functional currency. This includes the effect that foreign exchange rate fluctuations have on intercompany amounts due from our international subsidiaries to the U.S.
parent company, or to the other international subsidiaries, that are expected to be settled within the foreseeable future.

Foreign
currency gains or losses resulting from intercompany amounts due from our international subsidiaries to the U.S. parent company, or to the other international subsidiaries, that are not expected to be settled within the foreseeable future are
included in Other Comprehensive Income (Loss) during the period in which the exchange rates fluctuate.

Foreign exchange
transaction gains for the three months ended March 31, 2006 were $21,000 compared to a loss of $116,000 in the corresponding period of 2005. This change was due to changes in foreign currency exchange rates, and a strengthening on the U.S.
dollar which impacts U.S. dollar denominated intercompany amounts, specifically those intercompany amounts due from our international subsidiaries to the U.S. parent company that are expected to be settled within the foreseeable future.

Because we are subject to foreign currency exchange rate fluctuations, and because such fluctuations are part of the global economic environment, we
expect foreign currency gains and losses to continue to fluctuate in future quarters and years.

Income Tax Expense

Income tax expense for the three months ended March 31, 2006, and 2005 was $8,000 and $19,000, respectively. Utilization of net operating loss
carryforwards minimized our income taxes in each of the periods reported. This is expected to continue for the remainder of 2006 and possibly into future periods. Changes in income tax expense from period to period are attributed primarily to
relative changes in the mix of operating income generated in the various tax jurisdictions in which we operate.

The Internal Revenue Code
contains provisions that limit the net operating loss and credit carryforwards available to be used in any given year upon the occurrence of certain events, including significant changes in ownership interests.

Deferred tax assets, which have arisen primarily as a result of these net operating losses and other tax credits, also reflect the effect of temporary
differences between the tax basis of assets and liabilities and the corresponding financial statement amounts.

Due to the uncertainty of
our ability to utilize our deferred tax assets, a valuation allowance has been established for financial reporting purposes equal to the amount of the net deferred tax assets. In the future, we will continue to evaluate the need for, and the amount
of, any valuation allowance on deferred tax assets based on whether the facts and circumstances at the time indicate it is more likely than not that a portion or all of the deferred tax assets will ultimately be realized.

Liquidity and Capital Resources

Cash, cash equivalents, and short-term investments increased from $9.9 million at December 31, 2005 to $11.1 million at March 31, 2006. Our working capital decreased from $7.4 million at December 31,
2005 to $7.3 million at March 31, 2006.

We generated $1.7 million in cash from operating activities during the three months ended
March 31, 2006 compared to $0.5 million generated from operating activities in corresponding period of 2005. The increase in operating cash inflows primarily relates to the decrease in accounts receivable, net, which was mainly due to
collections on the unusually high December 31, 2005 accounts receivable balance that resulted in part from the large license sale made in the fourth quarter of 2005 as discussed above under Software License revenue, as well as
increases in other net working capital components, other than cash and accounts receivable.

The difference between our net income and our
operating cash inflows is attributable to non-cash expenses included in net income, and changes in operating assets and liabilities, as presented below (in thousands):

Non-cash expenses consist of the amortization of intangible assets, including purchased
technology, depreciation and amortization of property and equipment, and stock-based compensation charges.

Investing activities resulted
in net cash outflows of $0.1 million for the three months ended March 31, 2006 compared to $0.6 million for the corresponding period in 2005. The lower use of cash in investing activities in the three months ended March 31, 2006 as
compared to corresponding period in 2005 was due a $0.5 million payment made in the corresponding period of 2005 to Lucent Technologies Inc. in acquiring title to the software code underlying the S programming language. This was offset
by higher capital expenditures for capital purchases in the period ended March 31, 2006 than in the corresponding period in 2005. These capital expenditures predominantly related to investments we made in our information technology
infrastructure, and we expect this investment to continue in future quarters of 2006.

Financing activities resulted in net cash outflows
of $24,000 in the three months ended March 31, 2006, compared to a $20,000 cash inflow in the corresponding period of 2005. The decrease in cash flows from financing activities relates to a reduction in the proceeds received from the exercise
of employee stock options and contributions to our employee stock purchase plan during the three months ended March 31, 2006, as compared to the corresponding period in 2005.

In March 2006, we renewed a working capital revolving line of credit and security agreement with Silicon Valley Bank. The terms provide for up to $3.0
million in borrowing availability through March 24, 2007. This facility is secured by our accounts receivable and allows us to borrow up to the lesser of 75% of our eligible accounts receivable or $3.0 million and bears interest at the prime
rate plus 1%. At March 31, 2006, the prime rate was 7.75%, and no amounts had been borrowed under the line of credit facility.

We
also had an outstanding balance on an equipment loan with Silicon Valley Bank, secured by underlying assets. We originally borrowed $450,000 under this facility in 2002. We entered the first quarter of 2006 with a $32,000 outstanding balance, which
was fully paid as of March 31, 2006. This loan called for interest equal to prime rate plus 1%, and was repaid over a 42-month period, ending in March 2006. As of March 31, 2006, future maturities of debt under these arrangements were
zero.

These credit facilities contain covenants that limit our net losses and restricts the amount of capital
expenditures not financed through the equipment term loan. In addition, we are prohibited under these facilities from paying dividends. We were in compliance with these covenants as of March 31, 2006.

At March 31, 2006, our principal unused sources of liquidity consisted of cash and cash equivalents of $10.8 million, $0.4 million in short-term
investments, and our bank line of credit. Our liquidity needs are principally for financing of accounts receivable, capital assets, strategic investments, product development, and flexibility in a dynamic and competitive operating environment.

We believe that our existing cash and cash equivalents and available bank borrowings will be sufficient to meet the capital requirements
of our business for the foreseeable future, so long as we continue maintain positive operating cash flows. However, we intend to make significant investments in our data analysis and text analysis products in the next twelve months. If during that
time the market for our products worsens, or if we otherwise suffer significant operating losses, we may need additional funds through public or private equity financing or from other sources in order to fund our operations. Presently, we have no
commitments for any additional financing, and, if funding does become necessary, we may be unable to obtain it on favorable terms, if at all.

Commitments

As of March 31, 2006, our contractual commitments associated with our operating leases, primarily for our
office space in Seattle, Washington, as well as other domestic and international locations, are as follows (in thousands):

Important Factors That May Affect Our Business, Our Operating Results and Our Stock Price

In addition to the other information contained in this report, you should carefully read and consider the following risk factors. If any of these risks is
actually realized, our business, financial condition or operating results could be adversely affected and the trading price of our common stock could decline.

Our operating results fluctuate and could fall below our expectations and those of securities analysts and investors, resulting in a decrease in our stock price.

Our operating results have varied widely in the past, and we expect that they could continue to fluctuate in the future. Our stock price could decrease if
our operating results for a particular quarter or year fall below our expectations or those of securities analysts and investors. Some of the factors that could affect the amount and timing of our revenues and related expenses and cause our
operating results to fluctuate include:



| |  |  | our primary reliance on one product family;
| | - |  | -------------------------------------------



| |  |  | our ability to compete in the highly competitive statistics, data mining and text analysis markets;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | market acceptance of open source alternatives to our products and services;
| | - |  | ---------------------------------------------------------------------------



| |  |  | our ability to penetrate new markets;
| | - |  | -------------------------------------



| |  |  | market awareness and acceptance of our products;
| | - |  | ------------------------------------------------



| |  |  | our ability to obtain government contracts and research grants;
| | - |  | ---------------------------------------------------------------



| |  |  | our ability to expand our sales and support infrastructure;
| | - |  | -----------------------------------------------------------



| |  |  | our ability to maintain our relationships with key partners;
| | - |  | ------------------------------------------------------------



| |  |  | elongated sales cycles and potential sales delays;

| |  |  | rapid changes in technology and our ability to develop, introduce and market new products on a timely basis;
| | - |  | ------------------------------------------------------------------------------------------------------------

| |  |  | our ability to maintain third-party licenses; and
| | - |  | -------------------------------------------------



| |  |  | defects or errors in our software, which may result in losses of customers or revenues.
| | - |  | ---------------------------------------------------------------------------------------

Because we cannot predict our revenues and expenses with certainty, our expectations of future profits or losses may differ from actual results. It is particularly difficult to predict the timing or amount of our
license revenues because:



| |  |  | our sales cycles are variable, typically ranging between one and eight months from our initial contact with a current or potential data analysis product customer, and much longer
for current or potential text analysis customers;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a substantial portion of our sales are completed at the end of the quarter and, as a result, a substantial portion of our license revenues are recognized in the last days of a
quarter;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount of unfulfilled orders for our products is typically small; and
| | - |  | -------------------------------------------------------------------------



| |  |  | delay of new product releases can result in a customers decision to delay execution of a contract or, for contracts that include the new release as an element of the contract,
will result in deferral of revenue recognition until such release.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Even though our revenues are difficult to predict with
certainty, we base our decisions regarding many of our operating expenses on anticipated revenue trends. Many of our expenses are relatively fixed, and we cannot quickly reduce spending if our revenues are lower than expected. As a result, revenue
shortfalls could result in significantly lower income or greater loss than anticipated for any given period, which could result in a decrease in our stock price.

We may incur losses in future periods, which could cause a decrease in our stock price.

As of March 31, 2006,
we had an accumulated deficit of over $26 million. We have had quarters in 2005 and 2004 in which we achieved only slight profits. A small shortfall in revenue or unexpected increase in expenses could cause us to suffer a quarterly net loss. Because
of this, and the fact that we are increasing our spending, we may experience losses and negative cash flows in the near term, even if sales of our products and services continue to grow.

While we have shown a trend of growth in revenue and profit in recent quarters, there is no guarantee that these trends will continue. We expect our
expenses to grow at a higher rate in 2006 than they did in 2005, in part due to our efforts to enhance our information technology resources, and in part due to our decision to increase our product development, sales and professional services
personnel costs to expand our market position, create new product and service offerings, and further increase acceptance and sales of our

solutions.We may not be able to increase our revenues sufficiently to keep pace with these growing expenditures, if at all, and as a result we may be
unable to achieve or maintain profitability in the future.

Further, in 2006 we have begun to recognize stock option and stock purchase
awards as compensation expense in accordance with FAS 123(R). Our reported expenses will increase as a result of this practice, and because the calculations we must use to determine the amount of expense consider many factors beyond our control, our
ability to predict the amount of expense associated with FAS 123(R) requirements will be limited.

In addition, if we are unable to grow
our revenues, we may be forced to discontinue certain research and/or development projects, which could limit our future product development opportunities.

If we do not attract and retain key employees or management team, our ability to execute our business strategy will be limited.

Our future performance will depend largely on the efforts and abilities of our key technical, sales, customer support, accounting and managerial personnel and on our ability to attract and retain them. We have
recently announced plans to add significantly to our domestic and European headcount. As a result, our ability to execute our business strategy will depend on our ability to recruit additional experienced senior managers and to retain our existing
executive officers. Departures of key executives could adversely impact our reputation and our ability to execute our business strategy. Due to competition for qualified employees, we may have difficulty recruiting officers and employees with
appropriate skills, and we may be required to increase the level of compensation paid to existing and new employees, which could materially increase our operating expenses.

In addition, our ability to attract and retain employees may be adversely affected by the market price of our common stock, which has fluctuated widely
in the past. Consequently, potential employees may perceive our equity incentives such as stock options as less attractive, and current employees whose options are no longer priced below market value may choose not to remain employed by us. Because
our key employees are not obligated to continue their employment with us, they could leave at any time.

If potential customers do not purchase the
S-PLUS product family, or if current customers do not continue to renew maintenance or license subscriptions, our revenues and operating results will be adversely affected.

License and maintenance revenues from the S-PLUS product and add-on modules account for a significant portion of our license revenues. Other products,
such as InFact and Insightful Miner, have not contributed consistent revenues to date. We expect license and maintenance revenues from the S-PLUS product family to continue to account for a substantial majority of our revenues in the near future. As
a result, factors adversely affecting the pricing of or demand for the S-PLUS product family, such as competition or technological change, could dramatically affect our operating results. If we are unable to successfully deploy current versions of
the S-PLUS product family and to develop, introduce and establish customer acceptance of new and enhanced versions of the S-PLUS product family, our revenues and operating results will be adversely affected.

If we are unable to compete successfully in the statistics, data mining and text analysis markets, our business will fail.

Our S-PLUS product suite targets the statistics and data analysis market. This market is highly competitive, fragmented and mature. We face competition in
the statistics and data analysis market primarily from large enterprise software vendors and from our potential customers information technology departments, which may seek to develop their own solutions. The dominant competitor in our
industry is SAS Institute. Other companies with which we compete include, but are not limited to, SPSS, Inc., StatSoft Inc., The Mathworks and Minitab, Inc. In addition to competition from other statistical software companies, we face competition
from providers of software for specific statistical applications. We also face competition from R, an open-source software package that performs operations similar to the S language that forms the core of our S-PLUS product.

##### Table of Contents

In the data mining and text analysis market, we face competition from many companies, including SAS
Institute, SPSS, IBM, NCR, Autonomy, FAST, Inxight, ClearForest and Attensity, many of which are much larger than we are.

In addition, as
we develop other new products, or attempt to expand our sales into new vertical and end-user markets, we may begin competing with companies with whom we have not previously competed. It is also possible that new competitors will enter our markets.
For example, we could also experience competition from companies in other sectors of the broader market for business intelligence software, like providers of on-line analytical processing, business intelligence and analytical application software,
as well as from companies in other sectors. If we are unable to maintain our current level of pricing or renewals for our products, future revenue streams generated by out software products may decrease.

In addition, as we develop other new products, or attempt to expand our sales into new vertical and end-user markets, we may begin competing with
companies with whom we have not previously competed. It is also possible that new competitors will enter our markets. For example, we could also experience competition from companies in other sectors of the broader market for business intelligence
software, like providers of on-line analytical processing, business intelligence and analytical application software, as well as from companies in other sectors. An increase in competitive pressures in our market or our failure to compete
effectively may result in pricing reductions, reduced gross margins and loss of market share.

Many of our competitors have longer
operating histories, greater name recognition, greater market share, larger customer bases and significantly greater financial, technical, marketing and other resources than we do.

Market acceptance of open source alternatives to proprietary software poses a threat to our potential growth in revenue and market share.

Our business model has been based upon customers agreeing to pay a fee to license software developed and distributed by us. In recent years, there has
been a growing challenge to the commercial software model. Under the non-commercial software model, open source software produced by loosely associated groups of unpaid programmers and made available for license to end users without charge is
distributed at nominal cost by firms that earn revenue on complementary services and products, without having to bear the full costs of research and development for the open-source software. The most notable example of open source software is the
Linux operating system, which has presented a competitive challenge to leading vendors of proprietary operating systems. In the markets we serve, we face similar challenges because of the availability of R, an open source implementation of the S
language that forms the core of our S-PLUS product. While we believe our products provide customers with significant advantages, the popularization of the non-commercial software model continues to pose a significant challenge to our business model.
To the extent open-source software gains increasing market acceptance, sales of our products may decline, we may have to reduce the prices we charge for our products, and revenue and operating margins may consequently decline.

If we do not expand our international operations and successfully overcome the risks inherent in international business activities, the growth of our business will
be limited.

To be successful, we must continue to expand our international operations and enter new international markets. This
expansion may be delayed as a result of operating expense reduction measures and general economic conditions. If we do expand internationally, it will require significant management attention and financial resources to successfully translate and
localize our software products to various languages and to develop direct and indirect international sales and support channels. Even if we successfully translate our software and develop new channels, we may not be able to maintain or increase
international market demand for our solutions. We, or our VARs or distributors, may be unable to sustain or increase international revenues from licenses or from consulting and customer support. In addition, our international sales are subject to
the risks inherent in international business activities, including:



| |  |  | costs of customizing products for foreign countries;
| | - |  | ----------------------------------------------------



| |  |  | export and import restrictions, tariffs and other trade barriers;
| | - |  | -----------------------------------------------------------------



| |  |  | the need to comply with multiple, conflicting and changing laws and regulations;

Our foreign subsidiaries operate primarily in local currencies, and their results are translated into U.S. dollars. We do
not currently engage in foreign currency contracts that are designed to hedge foreign currency risk, but we may do so in the future. Future currency exchange rate fluctuations may have an adverse effect on our results of operations in future
periods. Our operating results could be materially harmed if we enter into license or service agreements providing for significant amounts of foreign currencies with extended payment terms or extended implementation timeframes if the values of those
currencies fall in relation to the U.S. dollar over the payment period of the agreement.

If we are unable to penetrate new end-user markets with our
current and future products, the growth of our business will be limited.

We focus our statistics business on two vertical markets:
financial services and life sciences. In order to grow our business, we will need to expand into new end-user markets within these two vertical markets for our statistics software and services, and we must simultaneously develop and sell new
products that address these and other markets. We will need to simultaneously invest in the scalability and deployability of our statistics product offerings and in the further development and enhancement of our data mining and text analysis
products. These simultaneous investments may strain our financial resources and diffuse managements time and attention. If any of these initiatives fails, our business will not grow and could fail.

We may be required to raise additional funding if we suffer operating losses, and this funding may be unavailable on acceptable terms, if at all.

Our future revenues may be insufficient to support the expenses of our operations and the expansion of our business. We may
therefore need additional equity or debt capital to finance our operations. If we are unable to generate sufficient cash flow from operations or to obtain funds through additional financing, we may have to reduce some or all of our development and
sales and marketing efforts and limit the expansion of our business or cease operations.

We believe that our existing cash and cash
equivalents and available bank borrowings will be sufficient to meet the capital requirements of our core business for the foreseeable future, so long as we continue maintain positive operating cash flows. However, we intend to make significant
investments in our data analysis and text analysis products in the next twelve months. If during that time the market for our products worsens, or if we are otherwise suffer significant operating losses, we may need additional funds through public
or private equity financing or from other sources in order to fund our operations. We have no commitment for additional financing, and, if funding does become necessary, we may experience difficulty in obtaining it on favorable terms, if at all.

Our credit line and equipment term loan with Silicon Valley Bank contain covenants that require us to maintain a certain level of
profitability. Any additional financing we obtain may contain covenants that restrict our freedom to operate our business or may require us to issue securities that have rights, preferences or privileges senior to our common stock and may dilute
your ownership interest in us.

Many potential customers are not yet aware of the benefits of text analysis solutions utilizing relationship search
capabilities, and our products may not achieve market acceptance.

Our text analysis product, InFact, was released in 2002 and has
not contributed substantial revenues to date. The market for relationship search solutions like InFact is still emerging, with many competitors coming to market with alternative solutions. Growth in demand for and acceptance of these solutions, if
any, remains uncertain. Even if this market grows, businesses may purchase our competitors solutions or develop their own. If InFact does not achieve market acceptance, our business may not grow. If we are unable to maintain our current level
of pricing or renewals for our InFact, future revenue streams generated by our Text Analysis products may decrease.

Our business is sensitive to the risks associated with government funding decisions.

We regularly apply for and are granted research contracts from a variety of government agencies and funding programs. During the fiscal years 2001 through
2003, these contracts generated from $4.3 to $4.8 million annually in offsets to our research and development expenses. During 2004, we began realigning our research and development efforts to ensure that we only pursue projects that directly
support our business strategy. As a result of this realignment, we have applied for and received fewer government research contracts, and research contracts generated $2.9 million and $2.2 million in 2004 and 2005, respectively. Further reductions
in these offsets to our research and development expenses are possible and would negatively affect our operating results. We may not receive new funded research contracts or any renewals of government-funded projects currently in process, and we may
decide to cancel or reassign certain ongoing projects that are not aligned with our core business needs. The personnel and other costs associated with these programs are relatively fixed in the short run, and a sudden cancellation or non-renewal of
a major funding program or multiple smaller programs would be harmful to our operating results. A substantial portion of the research grant money we receive is granted to us based on our status as a small business, the definition of which varies
depending on the individual contract terms. If the number of our employees or the amount of our revenues ever grows beyond the limits prescribed in any of these contracts, we will no longer be eligible for such research contracts and we will have to
incur certain research and development expenses without the benefit of offsets.

Furthermore, a significant portion of our license revenues
come from U.S. government entities, as well as institutions, healthcare organizations and private businesses that contract with or are funded by government entities. Government appropriations processes are often slow and unpredictable and may be
affected by factors outside of our control. Reductions in government expenditures and termination or renegotiation of government-funded programs or contracts could adversely affect our revenues and operating results.

We may be unable to expand our sales organization, which could harm our ability to expand our business.

To date, we have sold our desktop products primarily through our telesales department while we have relied on our field sales force to sell our
server-based solutions and generate orders for multiple desktop licenses. We believe our future revenue growth will depend in large part on recruiting, training and retaining both telesales and direct sales personnel. Competition for such personnel
in the software industry is intense. Our growth will further depend on expanding our indirect distribution channels. These indirect channels include value added resellers, or VARs, distributors, original equipment manufacturer, or OEM, partners,
system integrators and consultants. If we experience difficulty in recruiting and retaining qualified telesales and direct sales personnel and in establishing third-party relationships with VARs, distributors, OEM partners and systems integrators
and consultants, our sales could be reduced or our sales growth limited. Even if we successfully expand our sales force and other distribution channels, the expansion may not result in expected revenue growth.

Our sales cycle is variable, and our limited ability to predict revenues could cause our operating results to fluctuate, which could cause a decline in our stock
price.

An enterprises decision to purchase statistics, data mining and text analysis software and services is discretionary,
involves a significant commitment of its resources and is influenced by its budget cycles. Our sales cycles can be variable, typically ranging between one and eight months from our initial contact with a potential customer to the issuance of a
purchase order or signing of a license or services agreement, although the amount of time varies substantially from customer to customer, making our revenues difficult to predict in the short term. Occasionally sales require substantially more time,
and sales cycles have recently shown to be substantially longer for higher-priced orders and for our text analysis product, InFact. In addition, sales delays could cause our operating results for any given period to fall below the expectations of
securities analysts or investors, which could result in a decrease in our stock price.

Our services business can be dependent on a few large customers, the unexpected loss of which would affect our
operating results and could cause a decline in our stock price.

We perform consulting projects primarily on a time-and-materials
basis, under which a customer may order us to cease work at any time. When the magnitude of any such project requires us to allocate a significant portion of our consulting time to its performance during a reporting period, the unplanned or
otherwise untimely cessation of the project would create a shortfall in revenue that would result in a negative impact on operating results for the services segment. We are currently engaged on one project that accounted for 8.9% of total revenues
during 2005. This project, and others like it, may exceed 10% of our total revenue in future quarters. We have allocated resources to this project that have limited, and may continue to limit, our ability to pursue other opportunities. If we cease
work on this project prior to its intended completion, we would suffer significant reductions in our expected level of revenue and would continue to bear the generally fixed costs associated with our professional services staff. This would have a
negative impact on our operating results.

We may have difficulty implementing in a timely manner the internal controls necessary to allow our
management to report on the effectiveness of our internal controls, and these reports may not reveal all material weaknesses or significant deficiencies with our internal controls.

We have implemented efforts to improve our internal controls, but they might not prove sufficient. We continue to evaluate our operational, financial and
accounting systems and our managerial controls and procedures to determine what additional changes, if any, might help us to manage our current operations better. We expect to incur significant expenditures to enhance our information technology
resources. Even with these additional expenditures, we might not be able to sufficiently enhance our systems, procedures and controls.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we may be required to furnish an internal controls report of managements assessment of the design and effectiveness of our internal controls as part of our Annual Report
beginning with the fiscal year ending December 31, 2007. Our auditors will then be required to attest to, and report on, managements assessment. In order to issue our report, our management must document both the design of our internal
controls and the testing processes that support managements evaluation and conclusion. This process will likely require us to hire additional personnel and engage outside advisory services, which will result in additional accounting and legal
expenses. In addition, the evaluation and attestation processes required by Section 404 are new and neither companies nor auditing firms have significant experience in complying with these requirements. Accordingly, we may encounter problems or
delays in completing the review and evaluation, the implementation of improvements and the receipt of an attestation by our independent auditors.

Additionally, during our assessment of internal controls, certain deficiencies may be discovered that will require remediation. This remediation may require implementing additional controls, the costs of which could have a material adverse
effect on our results of operations. If we are unable to implement the requirements of Section 404 in a timely manner or with adequate compliance, in addition to receiving an adverse opinion from our auditors, we might be subject to sanctions
or investigation by regulatory authorities. Any such action could adversely affect our business and financial results. Further, our testing may not reveal all material weaknesses or significant deficiencies in our internal controls. Material
weaknesses or significant deficiencies in our internal controls could have a material adverse effect on our results of operations.

Rapid changes in
technology could render our products obsolete or unmarketable, and we may be unable to introduce new products and services successfully and in a timely manner.

The business software market is characterized by rapid change due to changing customer needs, rapid technological developments and advances introduced by competitors. Existing products can become obsolete and
unmarketable when products using new technologies are introduced and new industry standards emerge. New technologies, including the rapid growth of the Internet and commercial acceptance of open source software, such as R, could result in changes in
the way software is sold or delivered. In addition, we may need to modify our products when third parties change software that we integrate into our products. As a result, the life cycles of our products are difficult to estimate.

##### Table of Contents

To be successful, we must continue to enhance our current product line and develop new products that
successfully respond to changing customer needs, technological developments and competitive product offerings. We may not be able to successfully develop or license the applications necessary to respond to these changes, or to integrate new
applications with our existing products. Past or future reductions in our research and development personnel may harm our ability to innovate and compete. We may not be able to introduce enhancements or new products successfully or in a timely
manner in the future. If we delay release of our products and product enhancements, or if they fail to achieve market acceptance when released, it could harm our reputation and our ability to attract and retain customers, and our revenues may
decline. In addition, customers may defer or forego purchases of our products if competitors, our major hardware, systems or software vendors or we introduce or announce new products or product enhancements. Finally, delays in any new research or
development efforts could cause delays in our general product development schedule, including causing delays in the release of new product versions, which could materially harm our maintenance revenues.

General or specific economic conditions could adversely affect our revenue growth and ability to forecast revenue.

We focus our statistics business primarily on the financial services and life sciences markets and are thus sensitive to changes in the specific economic
conditions that affect them. A substantial change in the economic condition of either or both of these markets will affect our ability to sell our products and to forecast sales.

In addition, our revenue growth and potential for profitability depend on the overall demand for statistics and data analysis, data mining and text
analysis software and services. Because our sales are primarily to corporate customers, our business also depends on general economic and business conditions. Changes in demand for computer software caused by a weakened economy, either domestic,
international or both, may affect our sales and may result in decreased revenues. As a result of inconsistent and weakened economic conditions, we may experience difficulties in collecting outstanding receivables from our customers.

If we are unable to develop and maintain effective long-term relationships with our key partners, or if our key partners fail to perform, our ability to sell our
solution will be limited.

We rely on our existing relationships with a number of key partners, including distributors and
third-party technology vendors that are important to worldwide sales and marketing of our solutions. In addition, to be successful and to more effectively sell our products to larger customers, we must develop successful new relationships with other
key partners. These key partners often provide enterprise software, consulting, implementation and customer support services, and endorse our solution during the competitive evaluation stage of the sales cycle. Although we seek to maintain
relationships with our key partners, and to develop relationships with new partners, many of these existing and potential key partners have similar, and often more established, relationships with our competitors. These existing and potential
partners, many of which have significantly greater resources than we have, may in the future market software products that compete with our solution or reduce or discontinue their relationships with us or their support of our solution.

We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively.

Our success depends in part on our ability to protect our proprietary rights, including our patents on InFact technology and our rights in the software
code underlying the S programming language that we purchased from Lucent Technologies Inc. in January 2004. To protect our proprietary rights, we rely primarily on a combination of patent, copyright, trade secret and trademark laws,
confidentiality agreements with employees and third parties and protective contractual provisions such as those contained in license agreements with consultants, vendors and customers, although we have not signed these agreements in every case.
Despite our efforts to protect our proprietary rights, unauthorized parties may copy aspects of our products and obtain and use information that we regard as proprietary. Historically, our products have not been physically copy-protected. In order
to retain exclusive ownership rights to all software developed by us, we license all software and provide it in executable code only, with contractual

##### Table of Contents

restrictions on copying, disclosure and transferability. As is customary in the industry, we generally license our products to end-users by use of a
shrink-wrap license. Certain specialized products may utilize a written, signed license agreement with the customer. The source code for most of our products is protected as a trade secret and as unpublished copyrighted work. Other
parties may breach confidentiality agreements and other protective contracts we have entered into, and we may not become aware of, or have adequate remedies in the event of, a breach. We face additional risk when conducting business in countries
that have poorly developed or inadequately enforced intellectual property laws. While we are unable to determine the extent to which piracy of our software products exists, we expect piracy to be a continuing concern, particularly in international
markets and as a result of the growing use of the Internet. In any event, competitors may independently develop similar or superior technologies or duplicate the technologies we have developed, which could substantially limit the value of our
intellectual property.

Delivery of our solutions may be delayed if we cannot continue to license third-party technology that is important to the
functionality of our solution.

We incorporate into our products software that is licensed to us by third-party software developers.
The third-party software currently offered in conjunction with our solution may become obsolete or incompatible with future versions of our products. Further, numerous individual and institutional licensors have contributed software code to S-PLUS
in exchange for little or no consideration, and some of these third parties may choose to revise or revoke their licensing terms with us. A significant interruption in the supply of this technology could delay our sales until we can find, license
and integrate equivalent technology. This could take a significant amount of time, perhaps several months, which would cause our operating results to fall below the expectations of securities analysts or investors and result in a decrease in our
stock price.

Intellectual property claims and litigation could subject us to significant liability for damages and result in invalidation of our
proprietary rights.

In the future, we may have to resort to litigation to protect our intellectual property rights, to protect our
trade secrets or to determine the validity and scope of the proprietary rights of others. Any litigation, regardless of its success, would probably be costly and require significant time and attention of our key management and technical personnel.
Although we have not been sued for intellectual property infringement, we may face infringement claims from third parties in the future. The software industry has seen frequent litigation over intellectual property rights, and we expect that
participants in the industry will be increasingly subject to infringement claims as the number of products, services and competitors grows and the functionality of products and services overlap. Infringement litigation could also force us to:



| |  |  | stop or delay selling, incorporating or using products that incorporate the challenged intellectual property;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | pay damages;
| | - |  | ------------



| |  |  | enter into licensing or royalty agreements, which may be unavailable on acceptable terms; or
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | redesign products or services that incorporate infringing technology, which we might not be able to do at an acceptable price, in a timely fashion or at all.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------

Our products may suffer from defects or errors, which could result in loss of revenues, delayed or limited market acceptance of our
products, increased costs and damage to our reputation.

Software products as complex as ours frequently contain errors or defects,
especially when first introduced or when new versions are released. Our customers are particularly sensitive to such defects and errors because of the importance of accuracy in software used in analyzing data. We have had to delay commercial release
of past versions of our products until software problems were corrected, and in some cases have provided product updates to correct errors in released products. Our new products or releases may not be free from errors after commercial shipments have
begun. Any errors that are discovered after commercial release could result in loss of revenues or delay in market acceptance, diversion of development resources, damage to our reputation, increased service and warranty costs or claims against us.

In addition, the operation of our products could be compromised as a result of errors in the third-party
software we incorporate into our software. It may be difficult for us to correct errors in third-party software because that software is not in our control.

Market risks may affect the value of our assets, cash flows and financial results.

We sell products, which are
developed in the U.S., worldwide and operate in the United Kingdom, France and Switzerland where we incur expenses and generate billings denominated in those local currencies. As a result, the value of our assets, cash flows and financial results
could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets. In addition, interest income and expense are sensitive to changes in the general level of U.S. interest rates,
particularly since our investments are in short-term instruments which may fluctuate in value over time.

Our stock price may be volatile.

The price of our common stock has been volatile over the past two years. Our common stock reached a high of $5.20 per share on
May 14, 2004 and traded as low as $1.13 per share on September 1, 2004. As a result of fluctuations in the price of our common stock, you may be unable to sell your shares at or above the price you paid for them. The trading price of our
common stock could be subject to fluctuations for a number of reasons, including



| |  |  | future announcements concerning us or our competitors;
| | - |  | ------------------------------------------------------



| |  |  | actual or anticipated quarterly variations in operating results;
| | - |  | ----------------------------------------------------------------



| |  |  | changes in analysts earnings projections or recommendations;
| | - |  | -------------------------------------------------------------



| |  |  | announcements of technological innovations;
| | - |  | -------------------------------------------



| |  |  | the introduction of new products;
| | - |  | ---------------------------------



| |  |  | changes in product pricing policies by us or our competitors;
| | - |  | -------------------------------------------------------------



| |  |  | loss of key personnel;
| | - |  | ----------------------



| |  |  | deficiencies in our internal controls;
| | - |  | --------------------------------------



| |  |  | proprietary rights litigation or other litigation; or
| | - |  | -----------------------------------------------------



| |  |  | changes in accounting standards that adversely affect our revenues and earnings.
| | - |  | --------------------------------------------------------------------------------

In addition, stock prices for many technology companies fluctuate widely for reasons that may be unrelated to operating results of these companies. These fluctuations, as well as general economic, market and political conditions, such as
national or international currency and stock market volatility, recessions or military conflicts, may materially and adversely affect the market price of our common stock, regardless of our operating performance and may expose us to class action
securities litigation which, even if unsuccessful, would be costly to defend and distracting to management. In the past, following periods of volatility in the market price of a companys securities, securities class action litigation has often
been instituted against these companies. Litigation brought against us could result in substantial costs and a diversion of managements attention and resources, which could have a material adverse effect on our business, financial condition
and operating results.
