QUEST SOFTWARE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)



|1. | Organization and Basis of Presentation
|-- | --------------------------------------

Quest
Software, Inc. (Quest, the Company, we, us or our) was incorporated in California in 1987 and is a leading developer and vendor of application, database and Windows management software
products. We also provide consulting, training, and support services to our customers. Our accompanying unaudited condensed consolidated financial statements as of September 30, 2007 and for the three and nine months ended September 30,
2007 and 2006, reflect all adjustments (consisting of normal recurring accruals) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. These financial statements have been
prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting principles for complete financial statements.

The information
included in this Quarterly Report on Form 10-Q should be read in conjunction with Managements Discussion and Analysis of Financial Condition and Results of Operations, Quantitative and Qualitative Disclosures About Market
Risk, and the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in Quests Annual Report on Form 10-K for the year ended December 31, 2006 (2006 Form 10-K). The results for the
interim periods presented are not necessarily indicative of the results that may be expected for any future period.

Recently Issued Accounting
Pronouncements

In June 2006 the Financial Accounting Standards Board (FASB) issued Financial Interpretation
(FIN) No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109.FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprises financial
statements in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes.FIN 48 prescribes a recognition thresholdandmeasurement attribute for the financial
statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. We
adopted FIN 48 on January 1, 2007. See Note 7 for more information about the impact of adoption of this guidance on our financial position, results of operations and cash flows.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements(SFAS 157), which defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, however, the FASB staff has
proposed a one year deferral for the implementation of SFAS 157 for other nonfinancial assets and liabilities. We will adopt this statement effective January 1, 2008. We do not expect the standard to have a material impact on our financial
position or results of operations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and
Financial Liabilities  Including an Amendment of FASB Statement No. 115, which permits entities to choose to measure many financial instruments and certain other items at fair value, on an instrument-by-instrument basis. The fair
value measurement election is irrevocable and requires that unrealized gains and losses are reported in earnings. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. We will adopt this statement effective
January 1, 2008. We do not expect the standard to have a material impact on our financial position or results of operations.

In
December 2007, the FASB issued SFAS No. 141 (Revised 2007),Business Combinations (SFAS 141R). SFAS 141R will significantly change the accounting for business combinations. Under SFAS 141R, an acquiring entity will be
required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition-date fair value with limited exceptions. SFAS 141R will change the accounting treatment for certain specific items, including:



| |  |  | Acquisition costs will be generally expensed as incurred;
| | - |  | ---------------------------------------------------------



| |  |  | Noncontrolling interests (formerly known as minority interests  see SFAS 160 discussion below) will be valued at fair value at the acquisition
date;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Acquired contingent liabilities will be recorded at fair value at the acquisition date and subsequently measured at either the higher of such amount or the amount
determined under existing guidance for non-acquired contingencies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | In-process research and development will be recorded at fair value as an indefinite-lived intangible asset at the acquisition date;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | Restructuring costs associated with a business combination will be generally expensed subsequent to the acquisition date; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------

SFAS 141R also includes a substantial number of new disclosure requirements. SFAS 141R applies prospectively to business
combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. Earlier adoption is prohibited. Accordingly, since we are a calendar year-end company
we will continue to record and disclose business combinations following existing GAAP until January 1, 2009. We expect SFAS 141R will have an impact on accounting for business combinations once adopted but the effect is dependent upon
acquisitions at that time.

In December 2007, the FASB issued SFAS No. 160,Noncontrolling Interests in Consolidated Financial
Statements - An Amendment of ARB No. 51(SFAS 160). SFAS 160 establishes new accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Specifically,
this statement requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements and separate from the parents equity. The amount of net income attributable to the noncontrolling
interest will be included in consolidated net income on the face of the income statement. SFAS 160 clarifies that changes in a parents ownership interest in a subsidiary that do not result in deconsolidation are equity transactions if the
parent retains its controlling financial interest. In addition, this statement requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. Such gain or loss will be measured using the fair value of the
noncontrolling equity investment on the deconsolidation date. SFAS 160 also includes expanded disclosure requirements regarding the interests of the parent and its noncontrolling interest. SFAS 160 is effective for fiscal years, and interim periods
within those fiscal years, beginning on or after December 15, 2008. Like SFAS 141R discussed above, earlier adoption is prohibited. We have not completed our evaluation of the potential impact, if any, of the adoption of SFAS 160 on our
consolidated financial position, results of operations and cash flows.



|2. | Stock Based Compensation
|-- | ------------------------

We have authorized the
issuance of an aggregate of 38.5 million shares of common stock to empl oyees, directors and consultants under the Quest Software, Inc. 1999 Stock Incentive Plan, as amended (the 1999 Plan) and the Quest Software, Inc. 2001 Stock
Incentive Plan (the 2001 Plan and, together with the 1999 Plan, the Plans). Non-qualified stock options granted under the Plans generally have a 10-year life and vest ratably over a four to five year period, generally at the
rate of 20% one year after the grant date and 10% semi-annually thereafter. The exercise price of all options granted under the Plans is to be established by the Plan Administrator; provided, however, that the Plans were amended in November 2007 to
require that the exercise price of stock options shall not be less than the market value of our common stock on the date of grant. The Plan Administrator for the Plans is the Compensation Committee of the Board of Directors, with certain authority
delegated to a secondary committee pursuant to the terms of Plans. As of September 30, 2007, 5.5 million shares were available for grant under the Plans. No options were granted or exercised during the three and nine months ended
September 30, 2007.

We account for stock-based compensation awards in accordance with the provisions of SFAS No. 123
(revised 2004), Share-Based Payment,which requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model. The value of the portion of the awards ultimately expected to vest is
recognized as expense over the requisite service period. We recognized stock-based compensation expense of $4.3 million and $14.0 million, or $2.8 million and $8.3 million net of tax, in our condensed consolidated income statements for the
three and nine months ended September 30, 2007 as compared to compensation expense of $6.6 million and $20.6 million, or $5.3 million and $15.9 million net of tax, for the three and nine months ended September 30, 2006. The decrease
in stock-based compensation expense is primarily due to the fact that no options have been granted since September 2006.

unvested stock options was $32.8 million, which is expected to be recognized over a weighted-average period of 2.7 years.

2007 Acquisitions

ScriptLogic Corporation In August 2007 we acquired ScriptLogic Corporation (ScriptLogic), a privately held company that provides
systems lifecycle management solutions for Windows-based networks, for purchase consideration of approximately $89.5 million, including $0.6 million in transaction costs. In connection with the acquisition, Quest also offered key members of the
management team of ScriptLogic an opportunity to participate in a post-closing incentive bonus plan in an aggregate amount of up to $8.0 million payable over a four-year period (the Incentive Plan). A portion of the payments under the
Incentive Plan will be based on the satisfaction of financial performance objectives and a portion of the payments will be based solely on continued employment. All bonus payments will be recorded as compensation expense in the periods such bonuses
are earned. Of the cash amount paid at closing, $12.0 million was deposited in an escrow account to secure certain indemnification obligations of the selling shareholders.

The acquisition has been accounted for as a purchase and the purchase price has been allocated primarily to goodwill and other intangible assets. Total
goodwill of $65.1 million was assigned $39.1 million and $26.0 million to the license and service segments of our business, respectively, and is not expected to be deductible for tax purposes. Goodwill allocation of 60% to licenses and 40% to
services is based on both historical and projected relative contribution from licenses and services revenues. Actual results of operations of ScriptLogic are included in our condensed consolidated financial statements from the date of acquisition.
Our preliminary allocation of the purchase price to assets and liabilities was as follows (in thousands):



|                                                       |  |   |         |

|Other non-current assets                               |  |   | 2,154   |  
|Other current liabilities                              |  |   | (3,060  | )
|Current and non-current deferred revenue               |  |   | (11,022 | )
|Non-current deferred tax liability                     |  |   | (14,520 | )
|                                                       |  |   |         |  
|Total purchase price                                   |  | $ | 89,479  |  
|                                                       |  |   |         |  

The allocation of the purchase price is preliminary and is expected to be finalized before the end
of 2007.

Other Acquisitions We completed three other acquisitions during the nine months ended September 30, 2007, each
of which have been fully consolidated. The aggregate consideration paid for these transactions totaled $24.6 million paid in cash, including $0.4 million of transaction costs, and was allocated as follows: $20.3 million to goodwill,
$6.3 million to intangible assets and $2.0 million to assumed liabilities, net of tangible assets acquired. Actual results of operations of these acquisitions are included in our consolidated financial statements from the effective dates
of the acquisitions.

The pro forma effects of all 2007 acquisitions, individually or in the aggregate, would not have
been material to our results of operations for the three and nine months ended September 30, 2007 and fiscal 2006 and, therefore, are not presented.

2006 Acquisitions

We completed two acquisitions during the nine months ended September 30, 2006, both of which have
been fully consolidated. The aggregate consideration paid for these transactions totaled $17.6 million paid in cash, including $0.6 million of transaction costs, and was allocated as follows: $13.8 million to goodwill, $3.6 million to
intangible assets, $0.9 million to In Process Research and Development (IPR&D), and $0.7 million to assumed liabilities, net of tangible assets acquired. Actual results of operations of these acquisitions are included in our
consolidated financial statements from the effective dates of the acquisitions.

The following represents the aggregate allocation of the
purchase price for the two companies to intangible assets and IPR&D (table in thousands):



|                                                                        |  |   |      
|----------------------------------------------------------------------- |  | - | -----
|Acquired technology with a weighted average useful life of 3.0 years    |  | $ | 3,120
|Customer relationships with a weighted average useful life of 4.8 years |  |   | 340  
|Non-compete agreements with a weighted average useful life of 2.6 years |  |   | 90   
|Acquired IPR&D                                                          |  |   | 850  
|                                                                        |  |   |      
|Total intangible assets and IPR&D                                       |  | $ | 4,400
|                                                                        |  |   |      

The amount allocated to IPR&D was written off at the respective dates of acquisition because
the IPR&D had no alternative uses and had not reached technological feasibility. The value assigned to IPR&D was determined utilizing the income approach by determining cash flow projections relating to identified IPR&D projects. The
stage of completion of each in-process project was estimated to determine the discount rates to be applied to the valuation of the in-process technology. Based upon the level of completion and the risk associated with in-process technology, we
applied discount rates that ranged from 28.4% to 33.0% to value the IPR&D projects acquired.

The pro forma effects of all 2006
acquisitions, individually or in the aggregate, would not have been material to our results of operations for the three and nine months ended September 30, 2007 and fiscal 2006 and, therefore, are not presented in a pro forma table.

We have in the past made,
and plan to continue to make, minority cost method investments in early stage private companies for business and strategic purposes. We made a minority cost method investment of $6.1 million in an early stage private company during the three months
ended September 30, 2007. We made minority cost method investments, aggregating $3.8 million in three early stage private companies during the nine months ended September 30, 2006. These investments were accounted for under the cost
method, as the equity securities do not have a readily determined market value and we do not have the ability to exercise significant influence. Our cumulative investments in non-consolidated companies are included as part of other assets in our
condensed consolidated balance sheet at September 30, 2007 and were valued at $11.7 million.

|7. | Income Tax Provision
|-- | --------------------

Effective Tax Rate.
During the three and nine months ended September 30, 2007, the provision for income taxes increased to $7.5 million and $25.8 million, respectively, from $2.6 million and $7.5 million in the comparable periods of 2006, representing an increase of
$4.9 million and $18.3 million. The effective income tax rate for the three and nine months ended September 30, 2007 was approximately 33.3% and 40.6%, respectively, compared to 19.6% and 22.7% in the comparable periods of 2006. The increase in our
effective tax rate for the three and nine months is substantially due to the mix of income between high and low tax jurisdictions, the impact of net operating losses and associated valuation allowances in certain foreign jurisdictions (as assessed
under FIN No. 18, Accounting for Income Taxes in Interim Periods) and the inclusion of interest expense related to prior period unrecognized tax benefits (as assessed under FIN 48).

Adoption of FASB Interpretation No. 48. Effective January 1, 2007, we adopted FIN 48. FIN 48 prescribes a more-likely-than-not threshold for
financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition of income tax assets and liabilities, classification of current and
deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods and income tax disclosures. At January 1, 2007, the balance of gross unrecognized tax
benefits was $29.0 million, of which approximately $21.0 million would impact the effective tax rate if recognized. The cumulative effects of applying this interpretation have been recorded as a decrease of $2.7 million to retained earnings, an
increase of $5.0 million to net deferred income tax assets and an increase of $7.7 million to income taxes payable as of January 1, 2007.

In conjunction with the adoption of FIN 48, we have classified uncertain tax positions as non-current income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of
our income tax provision. As of September 30 and January 1, 2007, the total amount of accrued income tax-related interest and penalties included in the Condensed Consolidated Balance Sheets was approximately $2.6 million and $1.5 million,
respectively.

As of September 30, 2007, we are no longer subject to U.S. federal audits for years through December 31, 2002. We were also
subject to examination in various state and foreign jurisdictions for the 1997-2006 tax years. We are currently under examination by the Internal Revenue Service for the 2004 tax year and the French Tax Authority for the 2001-2004 tax years.

We believe appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years. However, due to the
risk that audit outcomes and the timing of audit settlements are subject to significant uncertainty and as we continue to evaluate such uncertainties in light of current facts and circumstances, our current estimate of the total amounts of
unrecognized tax benefits could increase or decrease for all open tax years. As of the date of this report, we do not anticipate that there will be any material change in the unrecognized tax benefits within the next twelve months.



|8. | Net Income Per Share
|-- | --------------------

Basic earnings per share is
computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities by including other common stock
equivalents, including stock options, in the weighted-average number of common shares outstanding for a period, if dilutive.

The table
below sets forth the reconciliation of the denominator of the earnings per share calculation (in thousands):

|9. | Geographic and Segment Information
|-- | ----------------------------------

Operating
segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by our chief operating decision maker, or decision-making group, in assessing performance and in deciding how to
allocate resources.

Our reportable operating segments are Licenses and Services. The Licenses segment develops and markets licenses to use
our software products. The Services segment provides after-sale support for software products and fee-based training and consulting services related to our software products.

We do not separately allocate operating expenses to these segments, nor do we allocate specific assets to these segments. Therefore, segment information
reported includes only revenues, cost of revenues, and gross profit.

Reportable segment data for the three and nine months ended
September 30, 2007 and 2006, respectively, is as follows (in thousands):

Securities
Litigation. From June 2006 through August 2006 a number of purported Quest Software shareholders filed putative shareholder derivative actions against the Company, the members of our Board of Directors, and certain current or former
officers, alleging, among other things, that the defendants improperly dated certain Quest Software employee stock option grants. Two of these cases, Eng v. Smith, et al. (Case No. 06-cv-751 DOC(RNBx)) and Freedman v. Smith, et
al. (Case No. 06-cv-763 DOC(RNBx)) have been consolidated in the United States District Court for the Central District of California. The plaintiffs filed a consolidated amended complaint in November 2006 and a further amended consolidated
complaint in September 2007. In addition, two putative shareholder derivative actions, Patterson v. Aronoff, et al. (Case No. 06CC00115) andHodge v. Aronoff, et al. (Case No. 06CC06787),were filed in the California Superior
Court for the County of Orange. The state court derivative actions were consolidated in July 2006.

In August 2007, an additional putative
shareholder derivative action was filed against the Company (as nominal defendant), the members of our Board of Directors and certain current or former officers, alleging generally that the individual defendants violated United States securities
laws by improper stock option grant practices and related accounting and disclosures. This case, City of Livonia Employees Retirement System v. Smith, et al. (Case No. SACV07-901 DOC (ANx)) was also filed in the United States
District Court for the Central District of California.

The putative state and federal derivative actions identified above are collectively
referred to as the Options Derivative Actions. The plaintiffs in the Options Derivative Actions contend, among other things, that the defendants conduct violated United States and California securities laws, breached
defendants fiduciary duties, wasted corporate assets, unjustly enriched the defendants, and caused errors in our financial statements. The plaintiffs seek, among other things, unspecified damages and disgorgement of profits from the alleged
conduct, to be paid to the Company.

In November 2007, we entered into a Stipulation of Settlement with the plaintiffs in the Options
Derivative Actions, pursuant to which the Options Derivative Actions shall be settled and dismissed with prejudice, subject to approval of the U.S. District Court for the Central District of California, as to the Company and all of its current and
former officers and directors. As part of the settlement, the company agreed to adopt certain remedial measures and corporate governance changes, in addition to the actions taken by the Special Committee of the Companys Board arising from the
stock option investigation, and the plaintiffs will be entitled to payment of an amount representing their attorneys fees, which is expected to be provided by the Companys directors and officers liability insurance carrier.

In October 2006 a purported shareholder class action was filed in the United States District Court for the Central District of California
against Quest Software and certain of its current or former officers and directors, entitled Middlesex Retirement System v. Quest Software, Inc., et al. (Case No. CV06-6863 DOC (RNBx)) (the Options Class Action).
The essence of the plaintiffs allegations in the Options Class Action is that the Company improperly backdated stock options, resulting in false or misleading disclosures concerning, among other things, Quest Softwares financial
condition. Plaintiffs also allege that the individual defendants sold Quest Software stock while in possession of material nonpublic information, and that the defendants conduct caused damages to the putative plaintiff class. The plaintiff
asserts claims under Sections 10(b), 20(a) and 20A of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. In January 2007, the Court appointed Middlesex Retirement System as lead class plaintiff and entered a
stipulated order establishing a pleading schedule for the plaintiffs first amended complaint and the defendants response thereto. The first amended class action complaint was filed with the Court in March 2007. In October 2007, the Court
issued its order on the Companys motion to dismiss the amended class action complaint. The Court dismissed the plaintiffs claims under Section 10(b) with respect to Michael Lambert, the Companys former Chief Financial Officer,
and the plaintiffs claims under Section 20(a) with respect to the Company and to Doug Garn, the Companys President, which claims have been dismissed without prejudice. The Court also held in abeyance the plaintiffs claims
under Section 20A pending plaintiffs filing of an amended complaint. Otherwise, the Court denied the Companys motion to dismiss as it related to the Company and other individual defendants. The Company and the individual defendants
have filed a motion with the U.S. District Court requesting certification of the Courts order for interlocutory appellate review. The Company intends to defend the Options Class Action vigorously.

SEC Investigation and United States Attorneys Office Information Request. In June 2006 the Company received an informal request for
information from the staff of the Los Angeles regional office of the Securities and Exchange Commission regarding its option granting practices. In January 2007 the SEC issued a formal order of investigation and a subpoena for the production of
documents. The Company is cooperating with the SEC, but does not know when the inquiry and investigation will be resolved or what, if any, actions the SEC may require it to take as part of that resolution. Quest Software has also been informally
contacted by the U.S. Attorneys Office for the Central District of California (U.S. Attorneys Office) and has been asked to produce on a voluntary basis documents many of which it previously provided to the SEC. The
Company is fully cooperating with both the SEC and the U.S. Attorneys Office. Any action by the SEC, the U.S. Attorneys Office or other governmental agency could result in civil or criminal sanctions against the Company and/or
certain of its current or former officers, directors and/or employees.

Initial Public Offering Securities Litigation.In November
2001, the Company, three of its current and former officers (Individual Defendants) and the underwriters in the Companys initial public offering (IPO) were named as defendants in a consolidated shareholder lawsuit in
the United State District Court for the Southern District of New York. This case is one of a number of actions coordinated for pretrial purposes as In re Initial Public Offering Securities Litigation, 21 MC 92. Plaintiffs in the
coordinated proceeding have brought claims under the federal securities laws against approximately 300 companies, underwriters, and individuals, alleging generally that defendant underwriters engaged in improper and undisclosed activities concerning
the allocation of shares in the companies IPOs from late 1998 through 2000. The amended complaint in the Companys case seeks unspecified damages on behalf of a purported class of purchasers of its common stock between
August 13, 1999 and December 6, 2000. Pursuant to a tolling agreement, the Court dismissed the Individual Defendants without prejudice. In February 2003, the Court denied the Companys motion to dismiss the claims against
it. The issuer defendants and plaintiffs negotiated a stipulation of settlement for the claims against the issuer defendants, including the Company, which was submitted to the Court for approval in June 2004 and preliminarily approved in August
2005. In December 2006, the Court of Appeals for the Second Circuit overturned the certification of classes in the six test cases that were selected by the underwriter defendants and plaintiffs in the coordinated proceeding. Because class
certification was a condition of the settlement, it became unlikely that the settlement would receive final court approval. On June 25, 2007, the Court entered an order terminating the proposed settlement based upon a stipulation among the
parties to the settlement.

##### Table of Contents

On August 14, 2007, the plaintiffs filed a second amended class action complaint against the
Company. The amended complaint contains a number of changes, including changes to the definition of the purported class of investors, and the elimination of the Individual Defendants as defendants. On September 27, 2007, the
plaintiffs filed a motion for class certification against the Company. The Company filed a motion to dismiss the claims against it on November 14, 2007. It is uncertain whether the parties will be able to negotiate a revised or future
settlement that complies with the standards set forth in the Second Circuits decision. The Company believes that it has meritorious defenses to the plaintiffs claims and intends to defend the action vigorously.

Intellectual Property Litigation.In December 2006, Diagnostic Systems Corporation (DSC) filed a complaint for patent infringement
against Quest Software, Inc. and five other software companies. The complaint was filed in the United States District Court for the Central District of California, as Case No. SACV06-1211 CJc(ANx). DSC is a subsidiary of Acacia Research Corporation,
and asserts that it is the owner by assignment of all rights and interests in U.S. patent nos. 5,701,400 and 5,537,590, and that certain of Quests software products infringe these two patents. DSC seeks injunctive relief and damages. Quest
filed an answer denying infringement on the two patents asserted and asserting various affirmative defenses to DSCs claims. Discovery in this matter is only recently beginning. If any of our products were found to infringe such patents, the
patent holder could seek an injunction to enjoin our use of the infringing product. If we were required to settle such a claim, it could have a material impact on our business, results of operations, financial condition or cash flows.

Acquisitions. The Company has entered into escrow agreements with acquired companies to satisfy certain indemnification
obligations of selling shareholders. Certain of these escrow agreements designate Quest as the holder of the escrow money. As of September 30, 2007, we hold approximately $1.6 million in cash related to these agreements, all of which is
included in cash and cash equivalents.

General. The Company and its subsidiaries are also involved in other legal proceedings,
claims and litigation arising in the ordinary course of business.

In the normal course of our business, we enter into certain types of
agreements that require us to indemnify or guarantee the obligations of other parties. These commitments include (i) intellectual property indemnities to licensees of our software products, (ii) indemnities to certain lessors under office
space leases for certain claims arising from our use or occupancy of the related premises, or for the obligations of our subsidiaries under leasing arrangements, (iii) indemnities to customers, vendors and service providers for claims based on
negligence or willful misconduct of our employees and agents, (iv) indemnities to our directors and officers to the maximum extent permitted under applicable law, and (v) letters of credit and similar obligations as a form of credit
support for our international subsidiaries and certain resellers. The terms and duration of these commitments varies and, in some cases, may be indefinite, and certain of these commitments do not limit the maximum amount of future payments we could
become obligated to make thereunder; accordingly, our actual aggregate maximum exposure related to these types of commitments cannot be reasonably estimated. Historically, we have not been obligated to make significant payments for obligations of
this nature, and no liabilities have been recorded for these obligations in our financial statements included in this report, as the estimated fair value of these obligations as of June 30, 2007 was considered nominal.



|11. | Related Party Transactions
|--- | --------------------------

In August 2007 we
acquired ScriptLogic Corporation (ScriptLogic). See Note 3 above. Certain venture capital funds associated with Insight Venture Partners (the Insight Funds) previously holding shares of ScriptLogics preferred stock
became entitled to receive (in respect of those shares of preferred stock) cash in an aggregate amount of up to approximately $37.7 million (subject to claims against an indemnity escrow fund).

Jerry Murdock, a director of Quest Software, is a Managing Director and the co-founder of Insight Venture Partners and an investor in the Insight Funds.
Vincent Smith, Quests Chairman of the Board and CEO, and Raymond Lane and Paul Sallaberry, directors of Quest Software, are passive limited partners in one or more of the Insight Funds. As a result of their interests in the Insight Funds,
Messrs. Murdock, Smith, Lane and Sallaberry have interests in the ScriptLogic transaction. We believe that the financial interests of Messrs. Smith, Lane and Sallaberry in this transaction are not material to them.

##### Table of Contents

In 2000, we received a note receivable with a face amount of $15.8 million from one of our then executive
officers for the purchase of 339,200 shares of our common stock at a purchase price of $46.50 per share. The officer granted Quest a security interest in the shares and also assigned, transferred, and pledged the shares to Quest in order to secure
his obligations under the Note. The Company maintains physical possession of the certificates representing the shares purchased as collateral until payment of the principal and interest under the note is made. The former officer remained employed by
Quest as of September 30, 2007. The maturity date of the note receivable was August 2007, when the principal amount and accrued interest became due and payable. The note receivable bears interest at 6.33% per annum. We are pursuing
collection. The note receivable is deemed to be a non-recourse obligation of the former officer for financial reporting purposes as such we recorded the note as a reduction to shareholders equity in accordance with Emerging Issues Task Force
Issue No. 85-1, Classifying Notes Received for Capital Stock, and recorded a corresponding credit to common stock.

We believe
that all of the transactions set forth above were made on terms no less favorable to us than could have been otherwise obtained from unaffiliated third parties.

|Item 2: | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion of our financial condition and results of operations (MD&A) should be read in conjunction with the condensed
consolidated financial statements and notes to those statements included elsewhere in this Report. Certain statements in this Report, including statements regarding our business strategies, operations, financial condition and prospects are
forward-looking statements. Use of the words believe, expect, anticipate, will, contemplate, would and similar expressions that contemplate future events may identify
forward-looking statements.

Numerous important factors, risks and uncertainties affect our operations and could cause actual results to
differ materially from those expressed or implied by these or any other forward-looking statements made by us or on our behalf. Readers are urged to carefully review and consider the various disclosures described in Part II, Item 1A 
Risk Factors included in this Report, and in other filings with the SEC that attempt to advise interested parties of certain risks and factors that may affect our business. Readers are cautioned not to place undue reliance on
these forward-looking statements, which are based on current expectations and reflect managements opinions only as of the date thereof. We do not assume any obligation to revise or update forward-looking statements. Finally, our historic
results should not be viewed as indicative of future performance.

Overview

During the third quarter we noted that changes made previously within our sales organization were slower than planned at taking affect. This, coupled with
a more price competitive market led by the platform vendors placed downward pressure on our license revenue growth rate. As such, license revenue growth was primarily derived from our investment in Vizioncore and a partial quarters worth of
license revenue from the acquisition of ScriptLogic Corporation (ScriptLogic). While the aforementioned items accounted for the impact to license revenues, our services revenue continued to grow across all product lines. During the
quarter our services revenue growth rate was three times the rate of growth for our license business during the quarter. Thus, as the maintenance component of our services revenue carries overall lower selling expenses, we were able to generate an
increase in income from operations despite a lower rate of growth in license revenues. Exiting the third quarter we made further refinements to our North American sales organization to improve execution and better compete in the market.

In August 2007 we acquired ScriptLogic, a privately held company that provides systems lifecycle management solutions for Windows-based networks.
Revenues from sales of ScriptLogic products will be included in our revenues from core Windows Management products. Actual results of operations of ScriptLogic are included in our condensed consolidated financial statements from the date of
acquisition.

Our Company and Business Model

Quest Software, Inc. delivers innovative products that help IT organizations get more performance from their computing environment. Our product areas are Application Management, Database Management and Windows
Management. The focus of our products is based upon generating higher levels of performance, manageability and productivity throughout our customers IT infrastructure and with products and services that enable them to manage the investments
they have made within their IT environment.

We derive revenues from three primary sources: (1) software licenses,
(2) post-contract technical support services (referred to as PCS) and (3) professional consulting and training services (referred to as PSO). Our software licensing model is primarily based on perpetual license fees, and our license fees
are typically calculated either on a per-server basis or a per-seat basis.

PCS contracts entitle a customer to telephone or internet
support and unspecified maintenance releases, updates and enhancements. First-year PCS contracts are typically sold with the related perpetual software license and renewed on an annual basis thereafter at the customers option. Annual PCS
renewal fees are priced as a percentage of the net initial customer purchase price (which includes both the fee for a perpetual license and first year PCS). Revenue is allocated to first year PCS based on vendor-specific objective evidence
(VSOE) of fair value and amortized over the term of the maintenance contract, typically 12 months although at times we sell PCS with terms of greater than 12 months.

##### Table of Contents

Over the last few years revenues generated by our PCS offerings have become a larger contributor to the
total revenue base of the company. As our PCS customer base grows, the PCS renewal rate has a larger influence on the PCS revenue growth rate and the amount of new software license revenues has a diminishing effect. Therefore, the growth rate of
total revenues does not necessarily correlate directly to the growth rate of new software license revenues in a given period. The primary determinant of changes in our PCS revenue profile is the rate at which our customers renew their annual
maintenance and support agreements. If our PCS renewal rates were to decline materially, our PCS revenues and total revenues would likely decline materially as well. Although we do not currently expect our PCS renewal rates to deteriorate, there can
be no assurance they will not.

We also provide PSO services which relate to installation of our products and do not include significant
customization to or development of the underlying software code. Revenue is allocated to PSO services based on VSOE of fair value and recognized as the services are performed. Such revenues represent 11.7% and 11.6% of total service revenues for the
three and nine months ended September 30, 2007, respectively, and 13.2% and 13.6% for the three and nine months ended September 30, 2006, respectively.

Total revenues for the nine months ended September 30, 2007, includes approximately $5.5 million of revenue as a result of a change to the Companys revenue recognition practices for certain large reseller
transactions. In 2006 and prior years, revenue from those transactions was deferred until the related reseller account receivable was collected. The modified practice of recognizing revenue at the time of sale has been implemented effective as
of January 1, 2007 due to a change in circumstances involving improved cash collection histories with these resellers.

Our primary
expenses are our personnel costs, which include compensation, benefits and payroll related taxes, which are a function of our world-wide headcount. We estimate that these personnel related costs represented approximately 67% of total expenses in the
three and nine months ended September 30, 2007 and 2006. Our full-time employee headcount at the end of the third quarter in 2007 was approximately 3,150 compared to approximately 2,880 at the end of the third quarter in 2006 with the increase
due primarily to our acquisition of ScriptLogic in August 2007. Total stock-based compensation expense and related payroll taxes decreased from $6.6 million and $20.6 million in the three and nine months ended September 30, 2006 to $4.3 million
and $14.0 million in the three and nine months ended September 30, 2007, representing a 35% and 32% year-over-year change for the three and nine month periods, respectively, due primarily to the fact that no option awards have been granted
since September 2006. With the filing of this report and our other 2007 quarterly reports we expect option granting activity to resume in the first quarter of 2008.

We invest heavily in research and development in order to design, develop and enhance a wide variety of products and technologies. We have also maintained an approach of using acquisitions as a strategy to obtain
incremental products and technology that will be attractive to our customers. In addition, we are primarily a direct-sales driven organization that expends significant selling costs in order to secure new customer license sales and the follow-on PCS
revenue stream that can continue forward beyond the initial license sale.

Our foreign currency gains or losses are predominantly
attributable to translation gains or losses on our net balances of monetary assets and liabilities in our foreign subsidiaries, including accounts receivable and cash, which were primarily denominated in the Euro, and to a lesser extent, the British
Pound and Canadian Dollar. The foreign currency translation adjustments to these balance sheet items are calculated by comparing the currency spot rates at the end of a quarter to the spot rates at the end of the previous quarter. On this basis, we
recorded in other income, net, a gain of $2.8 million and $4.3 million for the three and nine months ended September 30, 2007, respectively, and a loss of $0.4 million and gain of $2.6 million in the same periods of 2006, representing a
year-over-year change of 751% and 68% for the three and nine month periods, respectively.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with generally accepted accounting principles requires us to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenue and expenses. On an on-going basis, we make and evaluate estimates and judgments, including those related to revenue recognition, asset valuations (including accounts receivable, goodwill
and intangible assets), stock-based compensation, income taxes and functional currencies for purpose of consolidation. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the
circumstances. Our estimates form the basis for making judgments about amounts and timing of revenue and expenses, the carrying values of assets, and the recorded amounts of liabilities that are not readily

apparent from other sources. Actual results may differ from these estimates and such estimates may change if the underlying conditions or assumptions change.
We have discussed the development and selection of the critical accounting policies with the Audit Committee of our Board of Directors, and the Audit Committee has reviewed our related disclosures. The critical accounting policies related to the
estimates and judgments listed above are discussed further in our Annual Report on Form 10-K for fiscal 2006 under Managements Discussion and Analysis of Financial Condition and Results of Operations. There have been no material changes to our
critical accounting policies or estimates during the nine months ended September 30, 2007, except for a change in our revenue recognition practices for reseller transactions described below and our adoption of Financial Accounting Standards
Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109 (FIN 48), discussed under the heading Recently Adopted Accounting Pronouncements.

We modified our practice of recognizing revenue from certain large reseller transactions at the time of sale as of January 1, 2007
due to a change in circumstances involving improved cash collection histories with these resellers. Total revenues for the nine months ended September 30, 2007 includes approximately $5.5 million of revenue as a result of this change. In
2006 and prior years, revenue from those transactions was deferred until the related reseller account receivable was collected.

Effective January 1, 2007, we adopted FIN 48. As a result of the implementation of FIN 48, we recognize
liabilities for uncertain tax positions based on the two-step process prescribed within the interpretation. Both steps presume that the tax position will be examined by the appropriate taxing authority that has full knowledge of all relevant
information. The first step is to evaluate the tax position for recognition by determining if, based on the weight of available evidence, it is more likely than not that the position will be sustained on examination. The second step requires us to
estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement with a taxing authority. It is inherently difficult and subjective to estimate such amounts, as this may require us to
determine the probability of various possible outcomes. We reevaluate these uncertain tax positions on a periodic basis. This evaluation is based on factors including, but not limited to, current year tax positions, expiration of statutes of
limitations, litigation, legislative activity, or other changes in facts and circumstances. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision in that period.

See Note 1 of our Notes to Condensed Consolidated Financial Statements for information regarding recently issued accounting
pronouncements.

Licenses Revenues Our Virtualization products by Vizioncore were the main
contributor to our overall license revenue growth. License revenues from our Windows Management products were flat despite the positive contribution from the acquisition of ScriptLogic, which was acquired on August 8, 2007. We noted declines
within our Application Management product area.

Services Revenues The primary driver of our 19.8% growth in services revenue
was the PCS renewals generated by a larger customer installed base created by license revenue growth from previous periods. PSO increased on a year-over-year basis due to implementations around our Application and Windows Management solutions.

##### Table of Contents

Cost of Services Cost of services primarily consists of personnel, outside consultants,
facilities and systems costs used in providing PCS and PSO. Cost of services does not include development costs related to bug fixes and upgrades which are classified in research and development and which are not separately determinable. Personnel
related costs increased by approximately $1.1 million, primarily due to growth in technical support headcount. Average headcount related to our technical support group increased approximately 12%. Cost of services as a percentage of service revenues
was 16.4% and 17.6% in the three months ended September 30, 2007 and 2006, respectively.

Amortization of Purchased Technology Amortization of purchased technology includes amortization of the fair value of acquired technology associated with acquisitions. The 11.9% increase in amortization of purchased technology is due to technology acquired in the second and
third quarters of 2007, partially offset by other purchased technologies being fully amortized prior to the quarter ended September 30, 2007. We expect amortization of purchased technology within the cost of revenues arising from acquisitions
completed prior to September 30, 2007 to be $4.2 million for the remaining quarter of 2007.

Sales and Marketing Sales and marketing expenses consist primarily of compensation
and benefit costs for sales and marketing personnel, sales commissions, related facilities and information systems (IS) costs, and costs of trade shows, travel and entertainment and various discretionary marketing programs. Sales and
marketing expense increased $4.4 million during the three months ended September 30, 2007 as compared to the same period in 2006. Personnel related costs increased approximately $3.3 million. The increase in personnel related costs is primarily
due to a 7% increase in average headcount within our direct sales and system engineering groups. The addition of ScriptLogic headcount contributed to this increase.

Research and Development Research and development expenses consist primarily of compensation and benefit costs for software developers who develop new products, bug fixes and upgrades to existing
products and at times provide engineering support for PCS services, software product managers, quality assurance and technical documentation personnel, associated facilities and IS costs and payments made to outside software development consultants
in connection with our ongoing efforts to enhance our core technologies and develop additional products. Research and development expense increased $2.6 million during the third quarter of 2007 when compared to the same period in 2006. Personnel
related costs, excluding stock-based compensation, increased approximately $2.6 million. Stock-based compensation decreased by $0.7 million during the three months ended September 30, 2007 as compared to the same period in 2006.

General and Administrative General and administrative expenses consist primarily of compensation and benefit costs for our executive,
finance, legal, human resources, administrative and IS personnel, and professional fees for audit, tax and legal services, associated facilities and IS costs. General and administrative expense increased $3.1 million during the third quarter of 2007
as compared to the same period in 2006. Personnel related costs, excluding stock-based compensation, increased $2.5 million. The increase in personnel related costs was primarily due to an 18% increase in headcount hired to support the
companys growth. The additional ScriptLogic headcount contributed to this increase. Professional consulting and legal fees increased by approximately $1.9 million. These increases were partially offset by a reduction of $1.0 million in
stock-based compensation expense.

Amortization of Other Purchased Intangible Assets Amortization of other purchased
intangible assets includes the amortization of customer lists, trademarks, non-compete agreements and maintenance contracts associated with acquisitions. We expect amortization of other purchased intangible assets within operating expenses arising
from acquisitions completed prior to September 30, 2007 to be $2.1 million for the remaining quarter of 2007

In-Process Research and Development In-process research and development expenses relate to
in-process technology acquired from Charonware in July 2006. These costs were charged to operations as the technologies had not reached technological feasibility and did not have alternative future uses at the date of acquisition.

Other Income, Net

Other income, net includes
interest income on our investment portfolio, gains and losses from foreign exchange fluctuations and gains or losses on other financial assets as well as a variety of other non-operating expenses, such as costs incurred with operating and
maintaining our corporate aircraft (which was sold in the fourth quarter of 2006) and the minority interest in Vizioncore. Other income, net increased to $7.0 million in the third quarter of 2007 from $1.1 million in the third quarter of 2006. Costs
related to operating and maintaining our corporate aircraft was $1.6 million in the three months ended September 30, 2006 with no such costs in 2007. Interest income was $4.5 million and $3.1 million in the three months ended September 30,
2007 and 2006, respectively. We had a foreign currency gain of $2.8 million in the 2007 quarter compared to a $0.4 million loss in the 2006 quarter. Our foreign currency gains or losses are predominantly attributable to translation gains or losses
on net monetary assets, including accounts receivable and cash, which were primarily denominated in the Euro, and to a lesser extent, the British Pound and Canadian Dollar.

Income Tax Provision

During the three months ended September 30, 2007, the provision for income
taxes increased to $7.5 million from $2.6 million in the comparable period of 2006, representing an increase of $4.9 million. The effective income tax rate for the three months ended September 30, 2007 was approximately 33.3% compared to 19.6%
in the comparable period of 2006. The increase in our effective tax rate for the three months is substantially due to the mix of income between high and low tax jurisdictions, the impact of net operating losses and associated valuation allowances in
certain foreign jurisdictions (as assessed under FIN No. 18, Accounting for Income Taxes in Interim Periods) and the inclusion of interest expense related to prior period unrecognized tax benefits (as assessed under FIN
48).

Licenses Revenues Increased sales of our Windows products, including the positive
contribution from the acquisition of ScriptLogic, continued to be the main driver of license revenue growth over the comparable period in the prior year. Vizioncores license sales of our Virtualization products also contributed to our overall
license revenue growth. Growth in these product areas was offset by a decrease in license revenues from our Database and Application Management products.

Services Revenues The primary driver of our 19.2% growth in services revenue was the PCS renewals across all product areas generated by a larger customer installed base created by license revenue growth
from previous periods. PSO increased on a year-over-year basis due to implementations around our Windows and Database Management solutions.

##### Table of Contents

Cost of Licenses Cost of licenses as a percentage of license revenues was 1.9% for the nine
months ended September 30, 2007 and 2006, respectively.

Cost of Services Cost of services as a percentage of service
revenues was 17.1% and 18.5% in the nine months ended September 30, 2007 and 2006, respectively. Personnel related costs increased approximately $2.2 million. The increase in personnel related costs was primarily due to a 10% increase in
technical support headcount. Fees paid to outside professional services consultants in connection with new system implementation support increased $1.0 million as the demand for our professional services exceeded our ability to provide these
services.

Amortization of Purchased Technology The 1.4% decrease in amortization of purchased technology is primarily due to
certain purchased technologies being fully amortized prior to January 1, 2007.

Sales and Marketing Personnel related costs, excluding stock-based compensation,
increased approximately $13.5 million. Stock-based compensation decreased by $1.0 million during the nine months ended September 30, 2007 as compared to the same period in 2006. The increase in personnel related costs is primarily due to a 4%
increase in average headcount within our direct sales and system engineering groups. The addition of ScriptLogic headcount contributed to this increase. Also the U.S. Dollar devaluation contributed approximately $4.7 million to the overall
increase in sales and marketing expense, $3.3 million of which is included in the increase in personnel related costs stated above.

Research and Development Research and development expense increased $4.5 million during the nine months ended September 30, 2007 when compared to the same period in 2006. Personnel related costs, excluding stock-based
compensation, increased approximately $5.9 million, offset by a $2.4 million reduction in stock-based compensation expense.

General and
Administrative General and administrative expense increased $8.6 million during the nine months ended September 30, 2007 as compared to the same period in 2006. Personnel related costs, excluding stock-based compensation, increased
$6.9 million. The period-over-period change in personnel related costs was primarily due to an increase of 14% in average headcount hired to support the companys growth. The addition of ScriptLogic headcount contributed to this increase. Fees
associated with the investigation of our historical stock option grant practices and related accounting that was conducted by the special committee of independent directors contributed $2.6 million to the overall increase in general and
administrative expenses for the nine months ended September 30, 2007. These increases were offset slightly by a reduction of $2.9 million in stock-based compensation expense.

Amortization of Other Purchased Intangible Assets The 2.8% decrease in amortization of other purchased intangible assets is primarily due
to certain intangible assets being fully amortized prior to January 1, 2007.

##### Table of Contents

In-Process Research and Development In-process research and development expenses relate to
in-process technology acquired from AfterMail in January of 2006 and Charonware in July of 2006. These costs were charged to operations as the technologies had not reached technological feasibility and did not have alternative future uses at the
date of acquisition.

Other Income, Net

Other income, net increased to $18.2 million in the nine months ended September 30, 2007 from $7.6 million in the same period of 2006. Interest income was $14.1 million and $7.5 million in the nine months ended September 30, 2007
and 2006, respectively. We had a foreign currency gain of $4.3 million and $2.6 million in the 2007 and 2006 periods, respectively. In the 2006 period other income, net also included costs incurred with operating and maintaining our corporate
aircraft which was sold in the fourth quarter of 2006.

Income Tax Provision

During the nine months ended September 30, 2007, the provision for income taxes increased to $25.8 million from $7.5 million in the comparable period of
2006, representing an increase of $18.3 million. The effective income tax rate for the nine months ended September 30, 2007 was approximately 40.6% compared to 22.7% in the comparable period of 2006. The increase in our effective tax rate for
the nine months is substantially due to the mix of income between high and low tax jurisdictions, the impact of net operating losses and associated valuation allowances in certain foreign jurisdictions (as assessed under FIN No. 18,
Accounting for Income Taxes in Interim Periods) and the inclusion of interest expense related to prior period unrecognized tax benefits (as assessed under FIN 48).

Liquidity and Capital Resources

Cash and cash
equivalents and marketable securities were approximately $366.1 million and $320.7 million as of September 30, 2007 and 2006, respectively. Cash and cash equivalents consisted of cash and highly liquid investments purchased with original
maturities of three months or less. Marketable securities consisted primarily of short-term investment-grade bonds and United States government and agency securities with original maturities of greater than three months. Our investment objectives
were to preserve principal and provide liquidity, while at the same time maximizing market return without significantly increasing risk. We generally hold investments in marketable securities until maturity.

Summarized cash flow information is as follows (in thousands):

Operating Activities

Our primary source of operating cash flows is the collection of accounts receivable from our customers. Our primary use of cash from operating activities is for compensation and personnel-related expenditures. We
intend to continue to fund our operating expenses through cash flows from operations.

The analyses of the changes in our operating assets
and liabilities are as follows:



| |  |  | Accounts receivable decreased to $109.9 million due to a decrease in daily sales and days sales outstanding (DSO), which resulted in a decrease in
operating assets, reflecting a cash inflow of $30.9 million for the nine months ended September 30, 2007. The remaining difference in the change in accounts receivable of $(7.8) million, relating to the impact of non-cash foreign currency
translation adjustments, is presented as part of the effect of exchange rate changes on cash and cash equivalents section of our condensed consolidated statements of cash flows. DSO is calculated by dividing the period end accounts
receivable by the average daily sales for the quarter. DSO fell from 73 days at December 31, 2006 to approximately 66 days at September 30, 2007 and our daily sales decreased to $1.7 million for the quarter ended September 30, 2007
compared to $1.8 million for the quarter ended December 31, 2006. Collection of accounts receivable and related DSO could fluctuate in future periods due to the timing and amount of our revenues and their linearity and the effectiveness of our
collection efforts.

| |  |  | One of the primary cash outflows within operating assets and liabilities during the nine months ended September 30, 2007 and 2006 was $34.4 million and $22.3
million, respectively, paid for taxes. The timing of these tax payments and with respect to the 2007 period, the impact from adopting FIN 48, resulted in a reduction to income taxes payable, reflecting a use of cash of $4.0 million and $14.6 million
for the nine months ended September 30, 2007 and 2006, respectively.

Investing Activities

Our primary source of investing cash flows was proceeds from the sale of marketable securities, typically at maturity. Our primary uses of cash from
investing activities were for capital expenditures and cash payments for acquisitions.

Capital expenditures in the nine months ended
September 30, 2006 included $3.9 million for leasehold improvements and furniture and fixtures for the lease of our new EMEA headquarters office in Maidenhead, United Kingdom.

Cash payments for acquisitions in the nine months ended September 30, 2007, consisted of $107.6 million net cash paid for our acquisition of the
assets from Workplace Architects, Inc. (excluding cash retained to secure Workplace Architects indemnification obligations), and all of the outstanding shares of Magnum Technologies, Inc., Invirtus, Inc. and Scriptlogic Corporation. We also
paid $6.1 in July of 2007 for a minority cost method investment in an early stage private company.

In the nine months ended
September 30, 2006 we used $21.3 million in cash to acquire two companies and to make minority cost-method investments in three early stage private companies. These acquisitions and investment activity are more fully described in Notes 3 and 5
of our Notes to Condensed Consolidated Financial Statements. In addition to the initial purchase price of these acquisitions, we have potential earn-out payment obligations. Our earn-out payment obligation with respect to all acquisitions completed
as of September 30, 2007 was immaterial.

We will continue to purchase property and equipment needed in the normal course of our
business. We also plan to use cash generated from operations and/or proceeds from investments in marketable securities to fund other strategic investment and acquisition opportunities that we continue to evaluate. We plan to use excess cash
generated from operations to invest in short and long-term marketable securities consistent with past investment practices.

Financing Activities

Our primary source of financing cash flows has historically been from the issuance of our common stock under our employee stock option
plans. We have also financed acquisitions and capital expenditures with net borrowings under a repurchase agreement in prior periods.

Because we announced our determination to restate our previously issued financial statements and have become delinquent in our periodic reporting obligations under the Securities Exchange Act of 1934, as amended, we determined that we could
no longer rely upon the Registration Statements on Form S-8 previously filed with the U.S. Securities Exchange Commission to register the shares of our common stock issuable upon exercise of stock options granted under our various stock option
plans. Accordingly, we took action in the third quarter of 2006 to block exercises of all stock options based on our determination that doing so was necessary to prevent violations of applicable securities law and as a result, we do not expect to
receive proceeds from the exercise of stock options until after all of our delinquent reports are filed with the SEC. With the filing of this report and our other 2007 quarterly reports we expect option exercising activity to resume in the first
quarter of 2008.

Based on our current operating plan, we believe that our existing cash, cash equivalents, investment balances and cash
flows from operations will be sufficient to finance our operational cash needs through at least the next 12 to 24 months. Our ability to generate cash from operations is subject to substantial risks as described in Item 1A  Risk
Factors of our Annual Report on Form 10-K for the year ended December 31, 2006. One of these risks is that our future business does not stay at a level that is similar to, or better than, our recent past. Should a general
economic downturn or similar event occur, or should the companys products become uncompetitive or less attractive to end customers, we may be unable to generate or sustain positive cash flow from operating activities. We would then be required
to use existing cash, cash equivalents and investment balances to support our working capital and other cash requirements. Also, acquisitions are an important part of our business model. As such, significant amounts of cash could and will likely be
used in the future for additional acquisitions or strategic investments. If additional funds are required to support our working capital requirements, acquisitions or other purposes, we may seek to raise funds through public or private equity or
debt financing or from other sources. We can provide no assurance that additional financing will be available at all or, if available, that we would be able to obtain additional financing on terms favorable to us.

|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

Foreign Exchange Risk

We are a U.S. Dollar functional company and transact business in a number
of different foreign countries around the world. In most instances, revenues are collected and operating expenses are paid in the local currency of the country in which we are transacting. Accordingly, we are exposed to both transaction and
translation risk relating to changes in foreign exchange rates.

Our exposure to foreign exchange risk is composed of the combination of
our foreign net profits and losses denominated in currencies other than the U.S. Dollar, as well as our net balances of monetary assets and liabilities in our foreign subsidiaries. These exposures have the potential to produce either gains or
losses depending on the directional movement of the foreign currencies versus the U.S. Dollar and our operational profile in foreign subsidiaries. Our cumulative currency gains or losses in any given period may be lessened by the economic
benefits of diversification and low correlation between different currencies, but there can be no assurance that this pattern will continue to be true in future periods. During the three and nine months ended September 30, 2007, we had a $2.8
million and $4.3 million foreign currency gain, respectively, compared to a $0.4 million loss and $2.6 million gain in the comparable periods in 2006.

The foreign currencies to which we currently have the most significant exposure are the Euro, the Canadian Dollar, the British Pound and the Australian Dollar. To date, we have not used derivative financial
instruments to hedge our foreign exchange exposures, nor do we use such instruments for speculative trading purposes. We regularly monitor the potential cost and benefits of hedging foreign exchange exposures with derivatives and there remains the
possibility that our foreign exchange hedging practices could change accordingly in time.

Interest Rate Risk

Our exposure to market interest-rate risk relates primarily to our investment portfolio. We have not used derivative financial instruments to hedge the
market risks of our investments. We place our investments with high-quality issuers and, by policy, limit the amount of credit exposure to any one issuer other than the United States government and its agencies. Our investments in marketable
securities consist primarily of investment-grade bonds and United States government and agency securities. Investments purchased with an original maturity of three months or less are considered to be cash equivalents. We classify all of our
investments as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses, net of tax, reported in a separate component of shareholders equity.

We presently do not intend to liquidate our short and long-term investments prior to their scheduled maturity dates. However, in the event that we did
liquidate these investments prior to their scheduled maturities and there were no changes in market interest rates, we could be required to recognize a realized loss on those investments when we liquidate. At September 30, 2007, we have an
unrealized loss of $0.8 million on our investments in debt securities compared to $1.1 million at September 30, 2006. Our remaining investment positions and duration of the portfolio would not be materially affected by a 100 basis point shift
in interest rates.

Information about our investment portfolio is presented in the table below, which states the amortized book value and
related weighted-average interest rates by year of maturity (in thousands):

|Item 4. | Controls and Procedures
|------- | -----------------------

Evaluation of
Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to provide reasonable assurance
that information required to be disclosed in reports filed under the Securities Exchange Act of 1934 (the Act) is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to
management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2007. Based on that
evaluation, management concluded that, as of that date, the Companys disclosure controls and procedures were not effective at the reasonable assurance level because of the identification of the material weakness in its internal control over
financial reporting, described below, which the Company views as an integral part of its disclosure controls and procedures.

Internal Control over
Financial Reporting, Financial Close and Reporting Process

As described in Item 9A of our Annual Report on Form 10-K for the
fiscal year ended December 31, 2006, the Company determined that a material weakness in our internal control over financial reporting related to our financial close and reporting process existed as of December 31, 2006. As of
September 30, 2007, this material weakness continued to exist and had not yet been remediated. A description of the material weakness in our internal control over financial reporting related to our financial close and reporting process is
provided below.

Our financial and accounting organization was not adequate to support our financial accounting and reporting needs given
the growth of our business. Furthermore, we failed to effectively design and implement our financial accounting system to facilitate the needs of our financial close process across all reporting units. Specifically, we did not maintain a sufficient
complement of personnel with an appropriate level of accounting knowledge and training in the application of GAAP, nor did we adequately use our financial accounting system commensurate with our financial reporting requirements to support the
financial reporting and close process. Moreover, due to the lack of sufficient staffing it was necessary to place undue reliance on external consultants to assist in the financial reporting and close process. The lack of a sufficient complement of
personnel with an appropriate level of accounting knowledge and training coupled with an inadequate design and implementation of our financial accounting system across all reporting units resulted in significant manual processes for the existing
personnel. This reduced the likelihood that such individuals could detect the need for a material adjustment to the Companys books and records or anticipate, identify, and resolve accounting issues in the normal course of performing their
assigned functions. This material weakness resulted in not only the need to record various adjustments, and a significant delay in the issuance of these financial statements, but also resulted in a more than reasonable possibility that a material
misstatement to the annual or interim financial statements would not have been prevented or detected.

Changes in Internal Control over Financial
Reporting

There was no change in internal control over financial reporting that occurred during the third quarter of 2007 that has
materially affected or is reasonably likely to materially affect our internal control over financial reporting, except as described below:



| |  |  | The company hired 2 additional managers for the revenue recognition team
| | - |  | ------------------------------------------------------------------------

Plan for Remediation of Material Weaknesses

We are undertaking efforts to improve our internal
controls over financial reporting and to remediate the material weakness identified above. The identified material weakness was caused, in part, by insufficient staffing of experienced, specialized accounting personnel. Therefore, our remediation
plan for the material weakness includes the hiring of additional personnel trained and experienced in the complex accounting areas of revenue recognition and revenue accounting as well as GAAP. In the interim, we have engaged a number of qualified
accounting personnel on a temporary basis to compensate for a lack of adequate permanent finance and accounting staff. With these additional resources, management has performed additional analysis and other post-closing procedures in an effort to
ensure our Consolidated Financial Statements are fairly stated as of and for the quarter ended September 30, 2007.



26



---

##### Table of Contents

We believe that the actions described above and resulting improvement in controls will generally
strengthen our disclosure controls and procedures, as well as our internal control over financial reporting, and will, over time, address the material weaknesses that we identified in our internal control over financial reporting as of
September 30, 2007. However, because many of the remedial actions we have undertaken are very recent and because they relate, in part, to the hiring of additional personnel and many of the controls in our system of internal controls rely
extensively on manual review and approval, the successful operation of these controls for, at least, several fiscal quarters may be required prior to management being able to conclude that the material weakness has been remediated.

Limitations on Effectiveness of Controls

Our
management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only
reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to
their costs. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, within Quest have been detected. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that internal controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PART IIOTHER INFORMATION



|Item 1A. | Risk Factors
|-------- | ------------

An investment in
our shares involves risks and uncertainties. You should carefully consider the factors described below before making an investment decision in our securities. The risks described below are the risks that we currently believe are material risks of
the business and the industry in which we compete.

Our business, financial condition and results of operations could be adversely affected
by any of the following risks. If we are adversely affected by such risks, then the trading price of our common stock could decline, and you could lose part or all of your investment.

Matters relating to or arising from our stock option investigation, including regulatory proceedings, litigation matters and potential additional expenses, may adversely affect our business and results of
operations

We have restated our consolidated financial statements for periods through March 31, 2006 to reflect the findings of a
voluntary, independent investigation of our stock option granting practices and related accounting. This investigation was conducted by a Special Committee of the Board of Directors with the assistance of independent outside legal counsel and
outside forensic accounting consultants. To date, we have incurred significant expenses related to legal, accounting, tax and other professional services in connection with the investigation, the related restatements and related regulatory inquiries
or proceedings and litigation matters, and may incur significant expenses in the future with respect to such matters. These events, even if resolved favorably, may be time-consuming, expensive and disruptive to normal business operations, and the
outcomes of regulatory proceedings or litigation matters are difficult to predict and could have a material adverse effect on our business, results of operations and financial condition.

Although we believe we have made appropriate judgments in determining the financial and tax impacts of our historical stock option granting practices, we
cannot provide assurance that the Securities and Exchange Commission (SEC) or the Internal Revenue Service (IRS) will agree with the manner in which we have accounted for and reported, or not reported, the financial and tax
impacts. For a discussion of the judgments underlying the revised measurement dates, see Managements Discussion and Analysis of Financial Condition and Results of Operations in Part II, Item 7 of our Annual Report on Form 10-K
for the year ended December 31, 2006. If the SEC or the IRS disagrees with our financial or tax adjustments or related disclosures and such disagreement results in material changes to our historical financial statements, we may be required to
further restate our prior financial statements, amend prior filings with the SEC or take other action that is not currently contemplated.

In June 2006 we received an informal request for information from the Securities and Exchange Commission regarding our stock option practices. In January 2007 we were informed that the SEC issued a formal order of investigation in the
matter. We have also been informally contacted by the U.S. Attorneys Office for the Central District of California and have been asked to voluntarily produce documents relating to our stock option granting practices. We are cooperating
with the SEC and the U.S. Attorneys Office in connection with these matters, but can not predict if, when or how they will be resolved or what, if any, actions we may be required to take as part of any resolution of these matters. Any action
by the SEC, the U.S. Attorneys Office or other governmental agency could result in civil or criminal sanctions against us and/or certain of our current and former officers, directors and employees.

Additionally, as discussed in Note 10 of our Notes to Condensed Consolidated Financial Statements, included in Item 1 of this Report, we currently
are engaged in civil litigation with parties that have alleged a variety of claims against Quest and certain of our current and former officers and directors relating to our stock option grant practices and related accounting. Although we and the
other defendants intend to defend these claims vigorously, there are many uncertainties associated with any litigation, and we cannot assure you that these actions will be resolved without substantial costs and/or settlement charges. We have entered
into indemnification agreements with each of our present and former directors and executive officers under which Quest is required to indemnify each such directors or executive officers against expenses, including attorneys fees, judgments,
fines and settlements, paid by such individual in connection with the pending litigation (other than indemnified liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest).

The resolution of the pending investigations by the SEC and U.S. Attorneys Office, the defense of
our pending civil litigation and any additional litigation relating to our past stock option grant practices or related restatement of our financial statements could result in significant costs and diversion of the attention of management and other
key employees.

If we do not maintain compliance with Nasdaq listing requirements, our common stock could be delisted, which could, negatively impact
the trading market for our securities and impact our ability to maintain equity-based stock incentive programs for our employees

As a
result of the stock option investigation and the restatement of our consolidated financial statements we could not timely file certain of our periodic reports with the SEC and, accordingly, our Common Stock was subject to delisting from the Nasdaq
Global Select Market. With our filing of all delinquent reports we have achieved full compliance with SEC reporting requirements. We were unable to solicit proxies for an annual meeting of shareholders in 2006 because we could not provide an
annual report to shareholders, and have not been in compliance with the Nasdaq requirement to hold an annual meeting of shareholders. We have also not held a 2007 annual meeting of shareholders. Our intention is to hold an annual meeting of
shareholders as soon as practicable following the filing of all of our delinquent periodic reports.

Our common stock could be delisted if
we are required to further restate or amend our filings or if we otherwise do not maintain compliance with applicable listing requirements. If our securities are delisted from the Nasdaq Global Select Market, they would subsequently be
transferred to the National Quotation Service Bureau, or Pink Sheets. The trading of our common stock through the Pink Sheets might reduce the price of our common stock and the levels of liquidity available to our
stockholders. In addition, the trading of our common stock through the Pink Sheets could materially and adversely affect our access to the capital markets and our ability to raise capital through alternative financing sources on terms
acceptable to us, or to raise capital at all. Securities that trade through the Pink Sheets are no longer eligible for margin loans, and a company trading through the Pink Sheets cannot avail itself of federal preemption of state securities or
blue sky laws, which adds substantial compliance costs to securities issuances, including pursuant to employee option plans, stock purchase plans and private or public offerings of securities. Increased compliance burdens can also
be expected to impact our ability to maintain and administer stock option programs and other forms of equity incentives for our employees, which could also impair our ability to recruit and retain key employees. If we are delisted in the future from
the Nasdaq Global Select Market and transferred to the Pink Sheets, we could also be subject to other negative implications, including the potential loss of confidence by suppliers, customers and employees and the loss of institutional investor
interest in our securities. Any or all of the foregoing consequences of delisting could adversely affect our business and results of operations.

We had
material weaknesses in internal control over financial reporting and cannot assure you that material weaknesses will not be identified in the future. If our internal control over financial reporting or disclosure controls and procedures are not
effective, there may be errors in our financial statements that could require a restatement or our filings may not be timely and investors may lose confidence in our reported financial information, which could lead to a decline in our stock price

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal control over financial
reporting as of the end of each year, and to include a management report assessing the effectiveness of our internal control over financial reporting in each Annual Report on Form 10-K. Section 404 also requires our independent registered
public accounting firm to attest to, and report on, managements assessment of our internal controls over financial reporting. In assessing the findings of the Special Committees review and the restatement set forth in this Report,
our management concluded that there were material weaknesses, as defined in the Public Company Accounting Oversight Boards Auditing Standard No. 2, in our internal controls over financial reporting as of December 31, 2006. See the
discussion included in Part I, Item 4 of this Report for additional information regarding our internal control over financial reporting.

Our management does not expect that our internal control over financial reporting will prevent all error or all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the
control systems objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Controls can be
circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. Over time, controls may become inadequate because changes in conditions or deterioration in the degree of
compliance with policies or procedures may occur. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

We cannot assure you that all significant deficiencies and material weaknesses identified in this Report
will be adequately remedied or will be fully remedied by any specific date, although we believe that our material weakness in internal controls relating to revenue recognition has been remedied as of the date of filing of this Report. In addition,
we can provide no assurances that significant deficiencies or material weaknesses in our internal control over financial reporting will not be identified in the future. Any failure to maintain or implement required new or improved controls, or
any difficulties we encounter in their implementation, could result in significant deficiencies or material weaknesses, cause us to fail to timely meet our periodic reporting obligations, or result in material misstatements in our financial
statements. Any such failure could also adversely affect the results of periodic management evaluations and annual auditor attestation reports regarding the effectiveness of our internal control over financial reporting required under
Section 404 of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder. The existence of a material weakness could result in errors in our financial statements that could result in a restatement of financial statements, cause
us to fail to timely meet our reporting obligations and cause investors to lose confidence in our reported financial information, leading to a decline in our stock price.

We may incur additional expenses in order to assist our employees with potential federal and state income tax liabilities which may arise under Section 409A of the Internal Revenue Code

As a result of our stock option investigation, we have determined that many of our outstanding stock option awards are deemed to have been granted at an
exercise price below the fair market value of our stock on the actual accounting measurement date. The primary adverse tax consequences are: (1) that the re-measured options vesting after December 31, 2004 are potentially subject to option
holder excise tax under Section 409A of the Internal Revenue Code (and, as applicable, similar excise taxes under state law); and (2) certain incentive stock options previously granted, could be deemed granted at below market value
producing incremental payroll tax liabilities. We have recorded approximately $0.6 million of expenses in the year ended December 31, 2006 relating to the anticipated settlement by the Company of federal and applicable state income taxes
on behalf of the Companys employees for tainted options that were exercised during 2006. Employees of the Company who continue to hold tainted options may be subject to additional taxes, penalties and interest under Section 409A if no
action is taken to cure the options from exposure under Section 409A before December 31, 2008.

Regarding potential future
liabilities associated with Section 409A, we have yet to determine whether we will either implement a plan to assist the affected employees for the amount of this tax, adjust the terms of the original option grant, or adjust the terms of the
original option grant and pay the affected employees an amount to compensate such employees for this lost benefit. As such, no additional expense has been recorded in the consolidated financial statements.

Our future success may be impaired and our operating results will suffer if we cannot respond to rapid market, competitive and technological conditions in the
software industry

The market for our software products and services is characterized by:



| |  |  | rapidly changing technology;
| | - |  | ----------------------------



| |  |  | frequent introduction of new products and services and enhancements to existing products and services by platform vendors of database, application and Windows
products and by our competitors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increasing complexity and interdependence of software applications;
| | - |  | -------------------------------------------------------------------



| |  |  | consolidation of the software industry;
| | - |  | ---------------------------------------



| |  |  | changes in industry standards and practices; and
| | - |  | ------------------------------------------------



| |  |  | changes in customer requirements and demands.
| | - |  | ---------------------------------------------

To maintain our competitive position, we must continue to enhance our existing products and develop new products and services, functionality, and technology that address the increasingly sophisticated and varied needs
of our customers and prospective customers, which requires significant investment in research and development resources and capabilities, involves significant technical and business risks and requires substantial lead-time and significant
investments in product development. If we fail to anticipate new technology developments, customer requirements, industry standards, or if we are unable to develop new products and services that adequately address these new developments,
requirements, and standards in a timely manner, or if we are incapable of timely bringing new or enhanced products to market, our products and services may become obsolete, we may not generate suitable returns from our research and development
investments, and our ability to compete may be impaired, our revenue could decline, and our operating results may suffer.

During the past three years, a large portion of our revenue growth has been attributable to the growth of
our Microsoft Systems Management products and services, and we have relied upon sustained revenue and cash flow generation from our database management products in order to fund sales, marketing and research and development initiatives associated
with our other product areas. We cannot provide any assurance that the revenues we derive from these product areas will continue to grow. In addition, over the last few years we have committed significant resources to development of new and enhanced
application management products and have expanded our sales and services organizations to address anticipated business opportunities presented by our expanding application management product and services lines. We cannot provide any assurance that
this strategy will be successful or that the release of our enhanced application management products or other new products or services will increase our revenue growth rate.

Our quarterly operating results may fluctuate in future periods and, as a result, we may fail to meet expectations of investors and analysts, causing our stock price to fluctuate or decline

Our revenues and operating results may vary significantly from quarter-to-quarter due to a number of factors. These factors include the following:



| |  |  | the size and timing of customer orders. See Variations in the size and timing of our customer orders and differing nature of our products and services could
expose us to revenue fluctuations and higher operating costs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the discretionary nature of our customers purchasing decisions and budget cycles;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the timing of revenue recognition for sales of software products and services;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the extent to which our customers renew their maintenance contracts with us;
| | - |  | ----------------------------------------------------------------------------



| |  |  | exposure to general economic conditions and reductions in corporate or public sector IT spending;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | changes in our level of operating expenses and our ability to control costs;
| | - |  | ----------------------------------------------------------------------------



| |  |  | our ability to attain market acceptance of new products and services and enhancements to our existing products;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | our ability to introduce new products or enhancements to existing products and services in a timely manner;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | our ability to maintain our field and inside sales organizations with adequate numbers of sales and services personnel, and to minimize our costs of sales and
marketing through efficient allocation of sales resources and methods to products having different sales characteristics and profiles;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the introduction of new or enhanced products and services by our competitors and changes in the pricing policies of these competitors;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the relative growth rates of competing operating system, database and application platforms and competitive conditions among vendors of these platforms;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the unpredictability of the timing, level of sales and subsequent revenue recognition of our expanded efforts within our indirect sales channels;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | costs related to acquisitions of technologies or businesses, including acquired in-process research and development and amortization costs for intangible assets and
possible impairments and uncertainties arising from the integration of products, services, employees and operations of acquired companies; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of releases of new versions of third-party software products that our products support or with which our products compete.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------

In addition, the timing of our software product revenues is difficult to predict and can vary
substantially from product-to-product and customer-to-customer. We budget our operating expenses on our expectations regarding future revenue levels. The timing of larger orders and customer buying patterns are difficult to forecast. Therefore, we
may not learn of shortfalls in revenue or earnings or other failures to meet our expectations until late in a particular quarter. As a result, if total revenues for a particular quarter are below our expectations, we would not be able to
proportionately reduce operating expenses for that quarter.

We have experienced seasonality in our orders and revenues, which may result
in seasonality in our earnings. The fourth quarter of the year typically has the highest orders and revenues for the year and higher orders and revenues than the first quarter of the following year. We believe that this seasonality results primarily
from the budgeting cycles of our customers being typically higher in the third and fourth quarters and, to a lesser extent, from the structure of our sales commission program. In addition, the tendency of some of our customers to wait until the end
of a fiscal quarter to finalize orders has resulted in higher order volumes towards the end of the quarter. We expect this seasonality to continue in the future.

Due to these factors, we believe that period-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indications of future performance. Fluctuations in our
results of operations are also likely to affect the market price of our common stock, if our operating results differ from expectations of investors or securities analysts, and may not be related to or indicative of our long-term performance.

Variations in the size and timing of our customer orders and differing nature of our products and services could expose us to revenue fluctuations and
higher operating costs

Our license revenues in any quarter are substantially dependent on orders booked and delivered in that quarter.
Our revenues in a given quarter could be adversely affected if we are unable to complete one or more large license transactions or if the contract terms were to prevent us from recognizing revenue during that quarter. The sales cycles for certain of
our software products can last from three to nine months, or longer, and often require pre-purchase evaluation periods and customer education, which can affect timing of orders. Further, we have often booked a large amount of our sales in the last
month, weeks or days of each quarter and delays in the closing of sales near the end of a quarter could cause quarterly revenue to fall short of anticipated levels. Finally, while a portion of our revenues each quarter is recognized from previously
deferred revenue, our quarterly performance will depend primarily upon current order volumes to generate revenues for that quarter. These factors may cause significant periodic variation in our license revenues. In addition, we incur or commit to
operating expenses based on anticipated revenue levels, and generally do not know whether revenues in any quarter will meet expectations until the end of that quarter.

Our product portfolio is engineered for a broad variety of operating system, database and application platforms, and having a diverse set of functions and features. Some products, such as our database management
products and other component products, are directed at database administrators and are generally sold at lower price points, and we strive to generate demand for these products through our telesales organization and marketing programs designed to
maximize lead generation and website traffic. Sales of other, enterprise-wide products, primarily SharePlex and Foglight, require substantial time and effort from our sales and support staff as well as involvement by our professional services
organizations and, to an increasing degree, our systems integrator partners. Large individual sales, or even small delays in customer orders, can cause significant variation in our revenues and adversely affect our results of operations for a
particular period. Historically, we have not placed significant reliance on large sales transactions in any given quarter, with a substantial volume of our revenues being driven from smaller transactions. However, if we encounter difficulty
sustaining our component product volumes, and cannot generate a sufficient number of large customer orders, or if customers delay or cancel such orders in a particular quarter, our revenues and operating results may be adversely affected. For these
reasons, we face increasing complexity in building and sustaining the optimum combination of field and inside sales personnel to address the various and changing sales and distribution characteristics of our products, which in turn impacts our
ability to manage and minimize our sales and marketing costs.

We rely heavily on our direct sales activities for license and services
revenues, including renewals of annual maintenance contracts. We have in the past restructured or made other adjustments to our sales force in response to management changes, product changes, performance issues and other internal considerations. We
recently made some adjustments to our coverage model to increase focus on global and other major accounts. Weve also recently increased headcount in our telesales and sales associate groups. These changes can result in a temporary lack of
focus and reduced productivity, which could have temporary negative effects on our license or services revenues.

Accordingly, if our revenue growth rates slow or our revenues decline, or if we fail to efficiently
correlate our sales and marketing resources to our various products and their differing sales and distribution strategies, our operating results could be seriously impaired because many of our expenses are relatively fixed in nature and cannot be
easily or quickly changed.

Many of our products are vulnerable to direct competition from Oracle and other platform vendors

We compete with Oracle in the market for database management solutions and the competitive pressure continues to increase. We expect that Oracles
commitment to and presence in the database management product market will increase in the future and therefore substantially increase competitive pressures. We believe that Oracle will continue to incorporate database management technology into its
server software offerings and expand their development products possibly at no additional cost to its users. Competition from Oracle with certain of our Database Management products including SharePlex and Quest Central for Oracle has increased over
the last two years and has continued to increase with Oracles introduction of the next version of its database, known as Oracle 11g. Oracle 11g has enhanced capabilities in the functions competitive with SharePlex, Quest Central for Oracle and
with the Oracle monitoring capabilities of Foglight including monitoring capabilities from the entire application stack. We believe increased competition from Oracle has materially depressed our SharePlex and Quest Central for Oracle revenues over
the last four years. Oracle recently released SQL Developer which competes with TOAD, our market leading Database Development product for Oracle databases which contributes significantly to our revenues and net income.

In addition to the increasing competitive pressure from Oracle, Microsoft has continually upgraded the functionality of its platform offerings, which we
also believe will increase competitive pressure for our Microsoft products in the future.

In some cases these types of platform
vendor-provided tools are bundled with the platform and in other cases they are separately chargeable products, albeit at significantly lower price points. The inclusion of the functionality of our software as standard features of the underlying
database solution or application supported by our products or sale at much lower cost could erode our revenues, particularly if the competing products and features were of comparable capability to our products. Even if the functionality provided as
standard features or lower costs by these system providers is more limited than that of our software, there can be no assurance that a significant number of customers would not elect to accept more limited functionality in lieu of purchasing our
products. Moreover, there is substantial risk that the mere announcements of competing products or features by large competitors such as Oracle could result in the delay or cancellation of customer orders for our products in anticipation of the
introduction of such new products or features.

Our migration products for Microsofts Active Directory and Exchange are vulnerable to fluctuations
in the rate at which customers migrate to these products

Our products for the migration, administration and management of
Microsofts Active Directory and Exchange products currently contribute approximately one-quarter of our Windows platform revenue. Our ability to sell licenses for our Active Directory and Exchange migration products depends in part on the rate
at which customers migrate to newer versions of Microsofts Active Directory or to newer versions of Microsoft Exchange, and from other messaging platforms to Exchange. If these migration rates were to materially decrease, our license revenues
from these migration products would likely decline.

Many of our products are dependent on database or application technologies of others; if these
technologies lose market share or become incompatible with our products, or if these vendors introduce competitive products or acquire or form strategic relationships with our competitors, the demand for our products could suffer

We believe that our success has depended in part, and will continue to depend in part for the foreseeable future, upon our relationships with providers
of major database and enterprise software programs, including Oracle, IBM, Microsoft and SAP. Our competitive advantage consists in substantial part on the integration between our products and products provided by these major software providers, and
our extensive knowledge of their products and technologies. If these companies for any reason decide to promote technologies and standards that are not compatible with our technologies, or if they lose market share for their database or application
products, our business, operating results and financial condition would be materially adversely affected. Furthermore, these major software vendors could attempt to increase their presence in the markets we



33

##### Table of Contents

serve by either introducing products that compete with our products or acquiring or forming strategic alliances with our competitors. These companies have
longer operating histories, larger installed bases of customers and substantially greater financial, distribution, marketing and technical resources than we do, as well as well-established relationships with many of our present and potential
customers, and may be in better position to withstand and respond to the current factors impacting this industry. As a result, we may not be able to compete effectively with these companies in the future, which could materially adversely affect our
business, operating results and financial condition.

If we fail to manage our operations and grow revenue or fail to continue to effectively control
expenses, our future operating results could be adversely affected

Historically, the scope of our operations, the number of our
employees and the geographic area of our operations and our revenue have grown rapidly. In addition, we have acquired both domestic and international companies. This growth and the assimilation of acquired operations and their employees could
continue to place a significant strain on our managerial, operational and financial resources. To manage our current growth and any future growth effectively, we need to continue to implement and improve additional management and financial systems
and controls. We may not be able to manage the current scope of our operations or future growth effectively and still exploit market opportunities for our products and services in a timely and cost-effective way.

We cannot assure you that our operating expenses will be lower than our estimated or actual revenues in any given quarter. If we experience a shortfall
in revenue in any given quarter, we likely will not be able to further reduce operating expenses quickly in response. Any significant shortfall in revenue could immediately and adversely affect our results of operations for that quarter. Also, due
to the fixed nature of many of our expenses and our current expectation for revenue growth, our income from operations and cash flows from operating and investing activities could be lower than in recent years.

Failure to develop and sustain additional distribution channels in the future may adversely affect our ability to grow revenues

We intend to direct additional efforts to drive domestic and international revenue growth through sales of our products and services through indirect
distribution channels, such as global hardware and software vendors, systems integrators, or value-added resellers. Our ability to increase future revenues depends on our ability to expand our indirect distribution channels. If we fail in our
efforts to maintain, expand and diversify our indirect distribution channels, our business, results of operations and financial condition could be adversely affected. Increasing activity in indirect distribution channels will present a number of
additional risks, including:



| |  |  | we may face conflicts between the activities of our indirect channels and our direct sales and marketing activities, which may result in lost sales and customer
confusion;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our channel partners can cease marketing and distributing our products and services with limited or no notice and with little or no penalty;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our channel partners may not be able to effectively sell our products and services;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | our channel partners may experience financial difficulties that might lead to delays, or even default, in their payment obligations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may not be able to recruit additional channel partners, or replace any of our existing ones; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | our channel partners may also offer competitive products and services, and may not give priority to marketing our products or services.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------

Intense competition in the markets for our products could adversely affect our results of operations

The markets for our products are highly competitive. As a result, our future success will be affected by our ability to, among other things,
outperform our competitors in meeting the needs of current and prospective customers and identifying and addressing new technological and market opportunities. Our competitors may develop more advanced technology, adopt more aggressive pricing
policies and undertake more effective sales and marketing campaigns and may be able to leverage more extensive financial, technical or partner resources. If we are unable to maintain our competitive position, our revenues may decline and our
operating results may be adversely affected.

Our operating results may be negatively impacted by fluctuations in foreign currency exchange rates

Our international operations are generally conducted through our international subsidiaries, with the associated revenues and related expenses, and
balance sheets, denominated in the currency of the country in which the international subsidiaries operate. As a result, our operating results may be harmed by fluctuations in exchange rates between the U.S. Dollar and other foreign currencies.
The foreign currencies to which we currently have the most significant exposure are the Canadian Dollar, the British Pound, the Euro and the Australian Dollar. To date, we have not used derivative financial instruments to hedge our exposure to
fluctuations in foreign currency exchange rates.

Our international operations and our planned expansion of our international operations expose us to
certain risks

We maintain research and development operations primarily in Canada, Australia, Russia and Israel, and continue to
expand our international sales activities, with particular focus in Asia Pacific (including Japan), as part of our business strategy. As a percentage of total revenues, revenues outside of North America were 35.1% and 36.1% for the three and nine
months ended September 30, 2007, respectively, and 36.0% and 34.3% for the three and nine months ended September 30, 2006, respectively. As a result, we face increasing risks from our international operations, including, among others:



| |  |  | difficulties in staffing, managing and operating our foreign operations;
| | - |  | ------------------------------------------------------------------------



| |  |  | difficulties in coordinating the activities of our geographically dispersed and culturally diverse operations;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in adapting our existing foreign operations, particularly in Asia, to the control structure and requirements of a US public entity given those Asian
countries historical environment and their cultural approach to conducting business;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | longer payment cycles and difficulties in collecting accounts receivable;
| | - |  | -------------------------------------------------------------------------



| |  |  | seasonal reductions in business activity during the summer months in EMEA and in other periods in other countries;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | increased financial accounting and reporting burdens and complexities;
| | - |  | ----------------------------------------------------------------------



| |  |  | difficulties in hedging foreign currency transaction exposures;
| | - |  | ---------------------------------------------------------------



| |  |  | limitations on future growth or inability to maintain current levels of revenue from international operations if we do not invest sufficiently in our international
operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potentially adverse tax consequences;
| | - |  | -------------------------------------



| |  |  | potential loss of proprietary information due to piracy, misappropriation or weaker laws regarding intellectual property protection;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in localizing our products;
| | - |  | ----------------------------------



| |  |  | political unrest or terrorism, particularly in areas in which we have facilities;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | our ability to adapt and conform to accepted local business practices and customs, including providing letters of credit or other forms of support to or for the
benefit of our subsidiaries or resellers;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | compliance with a wide variety of complex foreign laws and treaties, including employment restrictions; and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | compliance with licenses, tariffs and other trade barriers.
| | - |  | -----------------------------------------------------------

Operating in international markets also requires significant management attention and financial resources
and will place additional burdens on our management, administrative, operational and financial infrastructure. We cannot be certain that investment and additional resources required in establishing facilities in other countries will produce desired
levels of revenue or profitability. In addition, we have limited experience in developing localized versions of our products and marketing and distributing them internationally.

Acquisitions of companies or technologies may result in disruptions to our business and diversion of management attention

We have in the past made and we expect to continue to make acquisitions of complementary companies, products or technologies. Acquisitions require us to assimilate the operations, products and personnel of the
acquired businesses and train, retain and motivate key personnel from the acquired businesses. We may be unable to maintain uniform standards, controls, procedures and policies if we fail in these efforts. Similarly, acquisitions may subject us to
liabilities and risks that are not known or identifiable at the time of the acquisition or may cause disruptions in our operations and divert managements attention from day-to-day operations, which could impair our relationships with our
current employees, customers and strategic partners. We may have to use cash, incur debt or issue equity securities to pay for any future acquisitions. Use of cash or debt may affect our liquidity and use of cash would reduce our cash reserves and
reduce our financial flexibility. The issuance of equity securities for any acquisition could be substantially dilutive to our shareholders. In addition, our profitability may suffer because of acquisition-related costs or amortization costs for
intangible assets with indefinite useful lives. In consummating acquisitions, we are also subject to risks of entering geographic and business markets in which we have no or limited prior experience. If we are unable to fully integrate acquired
businesses, products or technologies with our existing operations, we may not receive the intended benefits of an acquisition.

Accounting for equity
investments in companies may affect our operating results

We have made equity investments in other software companies and a private
equity fund. We regularly consider opportunities to make equity investments in other companies focused on software development or marketing activities, and expect from time to time to complete additional investments. These investments are risky
because the market for the products and technologies being developed by these companies are typically in the early stages and may never materialize. In addition, we have made at least one investment in a private software company that has required us
to consolidate the results of operations of this company into ours and we may determine in the future to invest in additional companies at similar levels. Estimating the fair value of our equity investments is inherently subjective and may
contribute to volatility in our reported results of operations. We have recognized accounting charges due to the impairment of the value of our investments in the past and may need to do so again in the future if we cannot substantiate the fair
value of our strategic equity investments. If we are required to consolidate the operating results of these companies, use the equity method of accounting, or write down the value of our cost-method investments, our operating results may be
adversely affected.

We face risks associated with governmental contracting

We derive a portion of our revenues from contracts with the United States government and its agencies and from contracts with state and local governments
or agencies. Demand and payment for our products and services are impacted by public sector budgetary cycles and funding availability, with funding reductions or delays adversely impacting public sector demand for our products and services. Public
sector customers may also change the way they procure new contracts and may adopt new rules or regulations governing contract procurement, including required competitive bidding or use of open source products, where available. These
factors may limit the growth of or reduce the amount of revenues we derive from the public sector, which could negatively affect our results of operations.

We may not generate increased business from our current customers, which could slow our revenue growth in the future

Most
of our customers initially make a purchase of our products for a single department or location. Many of these customers may choose not to expand their use of our products. If we fail to generate expanded business from our current customers, our
business, operating results and financial condition could be materially adversely affected. In addition, as we deploy new modules and features for our existing products or introduce new products, our current customers may choose not to purchase this
new functionality or these new products. Moreover, if customers elect not to renew their maintenance agreements, our service revenues would be materially adversely affected.

Failure to develop or leverage strategic relationships could harm our business by denying us selling opportunities and
other benefits

Our development, marketing, and distribution strategies rely increasingly on our ability to form strategic
relationships with software and other technology companies. These business relationships often consist of cooperative marketing programs, joint customer seminars, lead referrals, and cooperation in product development. Many of these relationships
are not contractual and depend on the continued voluntary cooperation of each party with us. Divergence in strategy or change in focus by, or competitive product offerings by, any of these companies may interfere with our ability to develop, market,
sell, or support our products, which in turn could harm our business. Further, if these companies enter into strategic alliances with other companies or are acquired, they could reduce their support of our products. Our existing relationships may be
jeopardized if we enter into alliances with competitors of our strategic partners. In addition, one or more of these companies may use the information they gain from their relationship with us to develop or market competing products.

Failure to adequately protect our intellectual property rights could harm our competitive position

Our success and ability to compete are dependent on our ability to develop and maintain the proprietary aspects of our technology. We generally rely on a
combination of trademark, trade secret, patent, copyright law and contractual restrictions to establish and protect our proprietary rights in our products and services.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. Litigation may be necessary in
the future to enforce our intellectual property rights, to protect our trade secrets, and to determine the validity and scope of the proprietary rights of others. Any such resulting litigation, whether successful or unsuccessful, could result in
substantial costs and diversion of management and financial resources, which could harm our business.

Our means of protecting our
proprietary rights may prove to be inadequate and competitors may independently develop similar or superior technology. Policing unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent
misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. We also believe that, because of the rapid rate of technological change in the software
industry, trade secret and copyright protection are less significant than factors such as the knowledge, ability and experience of our employees, frequent product enhancements and the timeliness and quality of customer support services.

Third parties may claim that our software products or services infringe on their intellectual property rights, exposing us to litigation that, regardless of merit,
may be costly to defend

Our success and ability to compete are also dependent upon our ability to operate without infringing upon the
proprietary rights of others. Third parties may claim that our current or future products infringe their intellectual property rights. Any such claim, with or without merit, could have a significant effect on our business and financial results. Any
future third party claim could be time consuming, divert managements attention from our business operations and result in substantial litigation costs, including any monetary damages and customer indemnification obligations, which may result
from such claims. In addition, parties making these claims may be able to obtain injunctive or other equitable relief affecting our ability to license the products that incorporate the challenged intellectual property. As a result of such claims, we
may be required to obtain licenses from third parties, develop alternative technology or redesign our products. We cannot be sure that such licenses would be available on terms acceptable to us, if at all. If a successful claim is made against us
and we are unable to develop or license alternative technology, our business and financial results and position could be materially adversely affected.

Our business may be adversely affected if our software contains errors or security flaws

The software products we offer
are inherently complex. Despite testing and quality control, we cannot be certain that errors or security flaws will not be found in current versions, new versions or enhancements of our products after commencement of commercial shipments.
Significant technical challenges also arise with our products because our customers purchase and deploy our products across a variety of computer platforms and integrate them with a number of third-party software applications and databases. If new
or existing customers have difficulty deploying our products or

##### Table of Contents

require significant amounts of customer support, our operating margins could be harmed. Moreover, we could face possible claims and higher development costs
if our software contains undetected errors or security flaws or if we fail to meet our customers expectations. As a result of the foregoing, we could experience:



| |  |  | loss of or delay in revenues and loss of market share;
| | - |  | ------------------------------------------------------



| |  |  | loss of customers;
| | - |  | ------------------



| |  |  | damage to our reputation;
| | - |  | -------------------------



| |  |  | failure to achieve market acceptance;
| | - |  | -------------------------------------



| |  |  | diversion of development resources;
| | - |  | -----------------------------------



| |  |  | increased service and warranty costs;
| | - |  | -------------------------------------



| |  |  | legal actions by customers against us which could, whether or not successful, increase costs and distract our management; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | increased insurance costs.
| | - |  | --------------------------

The
detection and correction of any security flaws can be time consuming and costly. In addition, a product liability claim, whether or not successful, could harm our business by increasing our costs and distracting our management.

We incorporate software licensed from third parties into some of our products and any significant interruption in the availability of these third-party software
products or defects in these products could reduce the demand for, or prevent the shipping of, our products

Certain of our software
products contain components developed and maintained by third-party software vendors. We expect that we may have to incorporate software from third-party vendors in our future products. We may not be able to replace the functionality provided by the
third-party software currently offered with our products if that software becomes obsolete, defective or incompatible with future versions of our products or is not adequately maintained or updated. Any significant interruption in the availability
of these third-party software products or defects in these products could harm our sales unless and until we can secure an alternative source. Although we believe there are adequate alternate sources for the technology licensed to us, such alternate
sources may not provide us with the same functionality as that currently provided to us.

Natural disasters or power outages could disrupt our business

A substantial portion of our operations is located in California, and we are subject to risks of damage and business disruptions
resulting from earthquakes, floods, wildfires and similar events, as well as from power outages. We have in the past experienced limited and temporary power outages in our California facilities due to power shortages, and we expect in the future to
experience additional power losses. While the impact to our business and operating results has not been material, we cannot assure you that natural disasters or power outages will not adversely affect our business in the future. Since we do not have
sufficient redundancy in our networking infrastructure, a natural disaster or other unanticipated problem could have an adverse effect on our business, including both our internal operations and our ability to communicate with our customers or sell
and deliver our products.

Failure to attract and retain personnel may negatively impact our business

Our success and ability to compete depends largely on the continued contributions of our key management, sales, engineering, marketing, support,
professional services and finance personnel. We have recently had moderate turnover in our sales and research and development organizations, significant turnover in the management of our accounting and finance department, and many key positions are
held by people who are new to the Company or to their roles. If these people are unable to quickly become familiar with the issues they face in their roles or are not well suited to their new roles, then this could result in the Company having
problems in executing its strategy or in reporting its financial results. We are uniquely

dependent upon the talents, relationships and contributions of a few executives and have no guarantee of their retention. We have been targeted by
recruitment agencies seeking to hire our key management, finance, engineering, sales and marketing and professional services personnel.

We
historically have used stock options as a significant component of our employee compensation program in order to align employees interests with the interests of our shareholders, encourage employee retention and provide competitive
compensation packages. During the pendency of our stock option investigation and related restatement, we were unable to continue granting stock options to new and existing employees and did not permit exercises of outstanding stock options. These
actions have impacted our overall competitive posture with respect to employee compensation and retention of qualified personnel. If we are unable to hire or retain qualified personnel, or if newly hired personnel fail to develop the necessary
skills or fail to reach expected levels of productivity, our ability to develop and market our products will be weakened.
