all adjustments, consisting of normal recurring adjustments and those items discussed in these Notes, necessary for a fair presentation of our financial position, as of September 30, 2010, the results of operations for the three and nine months
ended September 30, 2010 and 2009, the cash flows for the nine months ended September 30, 2010 and 2009 and stockholders equity for the nine months ended September 30, 2010. Certain information and disclosures normally
included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these

Form 10-K for the fiscal year ended December 31, 2009, filed with the SEC. Operating results for the nine months ended September 30, 2010 are not necessarily indicative of the results that may be expected for the year ending
December 31, 2010.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant items subject to those
estimates and assumptions include, but are not limited to, the carrying amounts of property and equipment, intangible assets, goodwill, the allowance for doubtful accounts, the valuation of stock options, deferred income taxes and
contingent liabilities. Actual results could differ from those estimates.

Recently Adopted
Accounting Principles

In May 2009, the Financial Accounting Standards Board, or FASB, issued a standard that sets
forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements; the circumstances under which an
entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. This standard
is effective for interim and annual periods ending after June 15, 2009. We adopted this standard in the quarter ended June 30, 2009. This standard did not impact our consolidated financial results. In February 2010, the FASB amended
the guidance for SEC filers removing the requirement to disclose the date through which an entity has disclosed subsequent events. The reissuance disclosure requirements for subsequent events have been refined to apply only to revised financial
statements.

In January 2010, the FASB issued a standard that requires new disclosures about significant transfers in and
out of Levels 1 and 2 fair value measurements and separate disclosures about purchases, sales, issuances and settlements relating to Level 3 fair value measurements. This standard also clarifies existing disclosure requirements regarding inputs and
valuation techniques, as well as the level of disaggregation for each class of assets and liabilities for which separate fair value measurements should be disclosed. We adopted this standard in the quarter ended March 31, 2010, except for
the separate disclosures about purchases, sales, issuances and settlements relating to Level 3 measurements, which becomes effective for us at the beginning of fiscal year 2011. The adoption of this standard did not have a material impact, and
the deferred provisions of this standard are not expected to have a material impact, on our financial statements.

Fair
Value of Financial Instruments

The carrying amounts of our financial instruments, including cash equivalents, accounts
receivable, accounts payable and accrued liabilities, approximate their respective fair values, due to the short-term nature of these instruments.

We apply the authoritative guidance on fair value measurements for financial assets and liabilities and non-financial assets and liabilities, such as goodwill, indefinite-lived intangible assets
and property, plant and equipment that are measured at fair value on a non-recurring basis. The guidance defines fair value, thereby eliminating inconsistencies in guidance found in various prior accounting pronouncements, and increases
disclosures surrounding fair value calculations.

The guidance establishes a three-tiered fair value hierarchy that
prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows:

Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by us.

Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1.

Level 3: Inputs that are unobservable in the marketplace and significant to the valuation.

The following section describes the valuation methodologies we use to measure different financial assets and financial liabilities at
fair value.

In order to determine the fair value of our money market funds, we use quoted prices in active markets for
identical assets. Therefore, our money market funds are considered a Level 1 item. We currently have no financial instruments that qualify as Level 2 items.

The fair value of the contingent consideration related to the asset purchase agreement with Tek-Tools, Inc., or Tek-Tools, was recorded in our condensed consolidated balance sheet at September 30,
2010 as an accrued earnout (see Note 8 for further details on the determination of fair value). The increase of $0.2 million in the fair value of contingent consideration for the three and nine months ended September 30, 2010 was due
to the passage of time and is recorded in other income (expense) in our condensed consolidated statements of

income. As of September 30, 2010, there have been no changes in the potential outcomes for payment since the acquisition as we still believe that there is a substantial likelihood that these
payments will be made.

The following table summarizes the basis used to measure certain financial assets and liabilities at
fair value on a recurring basis in our condensed consolidated balance sheets:

Long-Term Debt

On December 13, 2005, we entered into credit agreements with an investment management firm pursuant to which we
borrowed $85.0 million on a first lien note, or First Lien Note, and $25.0 million on a second lien note, or Second Lien Note, and collectively the Notes. In March 2010, we repaid the $19.1 million of outstanding principal on the
First Lien Note. In May 2010, we fully repaid the remaining $25.0 million of principal outstanding on the Second Lien Note.

The estimated fair value of the total amounts outstanding under the credit agreements at December 31, 2009 was $43.0 million and was determined in accordance with fair value disclosure requirements.
We estimated the fair value of the credit agreements by discounting future cash flows using interest rate spreads currently available for a credit agreement with similar terms and maturity to our existing outstanding borrowings. The total
outstanding borrowings at December 31, 2009 were recorded in our condensed consolidated financial statements at their aggregate carrying value of $44.1 million. We fully repaid the amounts outstanding under the Notes in 2010, and at
September 30, 2010, there were no outstanding borrowings recorded in our consolidated financial statements.

Debt
Issuance Costs

We amortize debt issuance costs over the term of the associated debt. The gross carrying amount of debt
issuance costs was $1.2 million and accumulated amortization was $0.8 million at December 31, 2009. In March 2010, we repaid the $19.1 million outstanding principal balance on our First Lien Note and wrote-off $0.2 million of debt issuance
costs associated with the note. In May 2010, we fully repaid the $25.0 million outstanding principal balance on our Second Lien Note and wrote-off the remaining $0.1 million of debt issuance costs. Interest expense includes the
amortization and write-off of debt issuance costs, which was $0 and $51,000 for the three months ended September 30, 2010 and 2009, respectively, and $0.4 and $0.7 million for the nine months ended September 30, 2010 and 2009,
respectively.

Income Taxes

We use the liability method of accounting for income taxes as set forth in the authoritative guidance for accounting for income taxes. Under this method, we recognize deferred tax liabilities and assets
for the expected future tax consequences of temporary differences between the respective carrying amounts and tax basis of our assets and liabilities.

We follow the
authoritative guidance on accounting for uncertainty in income taxes recognized in our financial statements which prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to
be taken on a tax return. We accrue interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Stock-Based Compensation

We have granted our employees and
directors stock-based incentive awards. These awards are in the form of stock options, restricted stock and restricted stock units. We measure stock-based compensation expense for all share-based awards granted based on the estimated fair value of
those awards on the date of grant. The fair values of stock option awards are estimated using a Black-Scholes valuation model. The fair value of restricted stock and restricted stock unit awards is determined using the fair market value of our
common stock based on the quoted market price on the date of grant.

Stock-based compensation reduced income before
income taxes by $2.3 million and $2.1 million for the three months ended September 30, 2010 and 2009, respectively, and $9.0 million and $5.6 million for the nine months ended September 30, 2010 and 2009, respectively. The income tax
benefit related to stock-based compensation was $0.6 million and $0.3 million for the three months ended September 30, 2010 and 2009, respectively, and $2.3 million and $0.9 million for the nine months ended September 30, 2010
and 2009, respectively. In June 2010, our former Executive Chairman retired and entered into a Severance Agreement and Release which provided for, among other things, an acceleration of the vesting of certain options, resulting in an
additional one-time stock-based compensation expense of $1.4 million. The income tax benefit related to this additional one-time stock-based compensation expense was $0.5 million.

An excess tax benefit arises when the tax deduction related to a stock option award is greater than the awards original grant date
fair value pursuant to the authoritative guidance. For financial reporting purposes, this excess tax benefit is not recorded as a tax benefit in our condensed consolidated statements of income and is instead treated as additional paid-in capital in
our condensed consolidated balance sheets. For the three months ended September 30, 2010, we recognized $12.0 million of tax benefits from the exercise of stock option awards, of which $10.2 million resulted in excess tax
benefits. For the nine months ended September 30, 2010, we recognized $19.9 million of tax benefits from the exercise of stock option awards, of which $17.4 million resulted in excess tax benefits. For the three months ended
September 30, 2009, we recognized $0.5 million of tax benefits from the exercise of stock option awards of which $0.5 million resulted in excess tax benefits. For the nine months ended September 30, 2009, we recognized $2.7 million of tax
benefits from the exercise of stock option awards of which $2.2 million resulted in excess tax benefits. These excess tax benefits are a reduction to our cash payments related to income taxes and must be reported as cash flows
from financing activities in our condensed consolidated statements of cash flows.

Reclassifications

Certain reclassifications have been made to the condensed consolidated balance sheet at December 31, 2009 to
conform with the September 30, 2010 presentation. These reclassifications had no effect on total assets, total liabilities, total stockholders equity or cash flows.

3. Business Combinations

On January 26, 2010, we acquired certain of
the assets of Tek-Tools, Inc., or Tek-Tools, for the following: (i) $26.0 million of cash; (ii) 362,138 shares of our common stock with a value of approximately $7.4 million based on the closing price of our common stock as reported on the
New York Stock Exchange on January 26, 2010; (iii) $2.0 million of cash and 90,535 shares of our common stock with a value of approximately $1.8 million based on the closing price of our common stock on the date of the acquisition, each

being held in escrow as security for breaches of representations and warranties, covenants and certain other expressly enumerated matters by Tek-Tools and its stockholders; (iv) $2.0 million
of cash being withheld to be paid upon the achievement of sales milestones of the acquired business during calendar year 2010; and (v) $2.0 million of cash being withheld to be paid upon the receipt of certain third party consents. See Note 8
for a further discussion of outstanding obligations related to the Tek-Tools acquisition.

Tek-Tools provided us an immediate
product offering of storage and virtualized server infrastructures that was missing from our product offerings and eliminated the normal time to market required to develop a new software product. We accounted for the Tek-Tools acquisition using the
purchase method of accounting. We allocated the purchase price to the assets acquired, including intangible assets, and liabilities assumed based on estimated fair values at the date of the acquisition. We estimated the value of assets and
liabilities based on purchase price and future intended use. We derived the value of intangible assets from the present value of estimated future benefits from the various intangible assets acquired. We also incurred direct acquisition costs of
approximately $0.4 million, which are included in general and administrative expense in our condensed consolidated statements of income. We included the operating results of Tek-Tools in our condensed consolidated financial statements from the
effective date of the acquisition.

We allocated the purchase price for Tek-Tools as follows (in thousands):

Goodwill represents the excess of the purchase price over the aggregate fair value of the net
identifiable assets acquired and is deductible for tax purposes. Goodwill for Tek-Tools resulted primarily from our expectations that we will now be able to offer customers of our network and application management products additional products that
provide visibility into storage performance and usage, virtualization and server performance and backup monitoring and analysis. Additionally, the Tek-Tools products will be used to attract new customers for storage, virtualization and network
management. We have integrated the Tek-Tools business into our broader IT management business and intend to integrate the storage and virtualization management products into our Orion family of products.

The following table presents our unaudited pro forma results of operations for the three and nine months ended September 30, 2010
and 2009 as if the acquisition had occurred at the beginning of the respective periods. The pro forma financial data for all periods presented include adjustments for the following: (i) elimination of interest expense from historical Tek-Tools
financial statements; (ii) recording the additional amortization expense from the identifiable intangible assets; (iii) adjusting the estimated tax provision of the pro forma combined results; and (iv) the issuance of our common stock
to Tek-Tools stockholders. Revenue is based on the purchase price allocation amount assigned to Tek-Tools deferred revenue of $2.4 million for the three and nine months ended September 30, 2010. The purchase price allocation amount assigned to
Tek-Tools deferred revenue was based on the fair value of the maintenance agreements we assumed and our future obligation to provide support to these customers. We prepared the pro forma financial information for the combined entities for

4. Goodwill and Other Intangible
Assets

At September 30, 2010 and December 31, 2009, we had goodwill in the amounts of $40.6 million and $15.4
million, respectively. The increase in goodwill in the nine months ended September 30, 2010 consisted of $25.2 million of goodwill associated with the Tek-Tools acquisition offset by a $0.1 million decrease from exchange rate fluctuations upon
consolidation of goodwill recorded in our foreign subsidiaries. We assess goodwill for impairment annually in the fourth quarter, or more frequently if other indicators of potential impairment arise. No impairment was noted at
December 31, 2009 and there were no indicators of potential impairment for our reporting unit at September 30, 2010.

We record intangible assets in accordance with the authoritative guidance for business combinations. The developed product technologies
that we acquired in the Tek-Tools acquisition were Tek-Tools Storage Profiler, Virtual and Server Profiler and Backup Profiler, which provide web based storage monitoring, virtualization and server monitoring and backup reporting and analysis
solutions. These product technologies were feasible at the date of acquisition as they were being actively marketed and sold by the acquired company at the acquisition date. We recognize the developed product technologies as intangible assets
separate from goodwill as they were capable of being separated or divided from the acquired entity and sold or licensed. We based the estimated useful lives of these assets primarily on future cash flows of the existing technologies considering
future development cycles. In addition to the developed product technologies, we also recorded intangible assets for the acquired companys customer relationships, trademarks and a non-competition covenant.

We use a useful life
for assets with finite lives of three to seven years for trademarks, customer relationships, non-competition covenants and acquired developed product technologies and ten years for intellectual property. As of September 30, 2010, we
estimated aggregate intangible asset amortization expense to be $0.8 million for the last quarter of 2010, $3.4 million in 2011, $3.3 million in 2012, $3.2 million in 2013 and $3.2 million in 2014. The expected amortization expense is an
estimate. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, changes in foreign currency exchange rates, impairment of intangible assets, accelerated amortization of intangible
assets and other events.

Other assets include capitalized software licenses and deposits. Capitalized software licenses were
$0.5 million at September 30, 2010 and $0 at December 31, 2009. The capitalized software licenses are amortized to cost of license revenue based on the number of units issued. Amortization of capitalized software licenses was $30,000 for
the three and nine months ended September 30, 2010. Deposits were $0.3 million at September 30, 2010 and $0.2 million at December 31, 2009.

5. Stockholders Equity and Stock-Based Compensation

All equity
awards issued subsequent to our initial public offering, or IPO, are granted under our 2008 Equity Incentive Plan, or 2008 Stock Plan. Our Amended and Restated Stock Plan, or the 2005 Stock Plan, was terminated at the time of our IPO for
purposes of granting any future equity awards under the plan. The 2005 Stock Plan will continue to govern the terms and conditions of all outstanding equity awards previously granted under the 2005 Stock Plan. At September 30, 2010, 7,170,058
shares of common stock were available for future grants under the 2008 Stock Plan.

The total
unrecognized stock-based compensation expense related to unvested stock options and subject to recognition in future periods was $16.1 million as of September 30, 2010 and we expect to recognize this expense over a weighted-average period of
2.72 years.

We estimated fair value for these stock options at the date of grant using the Black-Scholes option pricing model
with the following weighted-average assumptions:



|                         |  |                                     |            |

|Expected dividend yield  |  |                                     | 0.0%       | 
|Volatility               |  |                                     | 59.4%      | 
|Risk-free rate of return |  |                                     | 1.7 - 2.9% | 
|Expected life            |  |                                     | 6.02 years | 

We have not paid and
do not anticipate paying cash dividends on our common stock; therefore, we assumed the expected dividend yield to be zero. Since we were a private entity prior to our IPO in May 2009 with no historical data regarding the volatility of our own common
stock price, we based the expected volatility on the historical and implied volatility of comparable companies from a representative industry peer group. We determined expected volatility of options granted using an average of the historical
volatility measures of this peer group of companies. We based the risk-free rate of return on the average U.S. treasury yield curve for five- and seven-year terms for the nine months ended September 30, 2010. As allowed under current guidance,
we have elected to apply the simplified method in developing our estimate of expected life for plain vanilla stock options by using the midpoint between the vesting date and contractual termination date since we do not have
sufficient historical exercise data to provide a reasonable basis upon which to estimate an expected term due to the limited period of time our common stock has been publicly traded.

As of September 30, 2010, there were no restricted stock awards outstanding. All previously outstanding
restricted stock awards either vested as of the 2010 annual meeting of our stockholders held on May 21, 2010 or were forfeited prior to such time.

The total unrecognized stock-based compensation expense related to unvested restricted stock units and
subject to recognition in future periods was $3.4 million as of September 30, 2010 and we expect to recognize this expense over a weighted-average period of 3.31 years.

6. Earnings Per Share

We computed basic earnings per share using the
weighted-average number of our common shares outstanding during the reporting period. We adjusted diluted earnings per share for the after-tax impact of incremental shares that would be available for issuance upon the assumed exercise of stock
options.

Dilution from assumed exercises of stock options is dependent upon several factors, including the market
price of our common stock. During the three months ended September 30, 2010 and 2009, options to purchase approximately 1,313,000 and 44,000 shares of common stock, respectively, were outstanding but were not included in the computation of
diluted earnings per share because the average market price of the underlying stock did not exceed the sum of the option exercise price, unrecognized compensation expense and the excess tax benefit and thus the results would have been antidilutive.
The calculation of diluted earnings per share requires us to make certain assumptions related to the use of proceeds that would be received upon the assumed exercise of stock options. These assumed proceeds include the excess tax benefit that we
receive upon assumed exercises.

On August 2, 2010, our board of directors approved a share repurchase program,
authorizing us to purchase up to $25.0 million of our outstanding common stock. We were authorized to make purchases in the open market and purchases were funded from available working capital. The share repurchase program was completed in August
2010, and we repurchased 1.7 million shares of our common stock for an aggregate purchase price of $25.0 million. Shares were retired upon repurchase. Our policy related to repurchases of our common stock is to charge any excess of
cost over par value entirely to additional paid-in capital in absence of retained earnings.

7. Income Taxes

In the three months and nine months ended September 30, 2010, we recorded $5.9 million and $13.4 million of income tax expense,
respectively, resulting in an effective tax rate of 32.7% and 31.3%, respectively. In the three months and nine months ended September 30, 2009, we recorded $4.4 million and $10.4 million of income tax expense, respectively, resulting in
an effective tax rate of 30.1% and 31.2%, respectively. The increase in the effective tax rate for both periods in 2010 was primarily attributable to the non-renewal of the federal research and experimentation tax credit, which was partially
offset by our international revenue, which is taxed at a lower rate, becoming a larger percentage of our total revenue.

We recognize interest
and penalties related to unrecognized tax benefits in the provision for income taxes. In the three months and nine months ended September 30, 2010 and 2009, interest and penalties recorded were not significant. As of
September 30, 2010, we accrued an insignificant amount for the payment of interest related to unrecognized tax benefits.

We file U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2007 through 2009 tax
years remain open and subject to examination by federal and foreign tax authorities. The 2006 through 2009 tax years generally remain open and subject to examination by the state tax authorities. The statute of limitations for the 2006
federal tax year expired during the quarter ended September 30, 2010. We are not currently under audit in any major taxing jurisdiction.

8. Commitments and Contingencies

Legal Proceedings

From time to time, we have been and may be involved in various legal proceedings arising from our ordinary course of
business.

On September 13, 2010, Uniloc USA, Inc. and Uniloc (Singapore) Private Limited (Uniloc) brought a
lawsuit against SolarWinds, Inc. and SolarWinds Worldwide, LLC (collectively, SolarWinds) and several other defendants in the United States District Court for the Eastern District of Texas. The complaint filed by Uniloc alleges that
SolarWinds and each of the other fifteen named defendants software infringe U.S. patent 5,490,216 allegedly owned by Uniloc. Uniloc alleges that SolarWinds software, specifically its license key system, infringes
upon this patent that utilizes a system for activating software products through a registration process. Uniloc has brought a series of lawsuits against numerous software companies around the world and the infringement and damages related to
the patent at issue in the case is currently being challenged in the United States Court of Appeals for the Federal Circuit. Because this lawsuit is in its initial stages, it is not possible to reliably predict the outcome of the
litigation. Therefore, we cannot currently estimate the loss, if any, associated with the litigation. We intend to contest the claims associated with this lawsuit vigorously.

On October 15, 2010, a lawsuit was filed on behalf of Daniel Richardson against SolarWinds, Inc. and certain of its current and
former officers in the United States District Court for the Northern District of Texas. The lawsuit was filed on behalf of Richardson and a purported class of all persons who purchased or acquired shares of common stock of SolarWinds, Inc.
between February 8, 2010 and July 21, 2010 and alleges that SolarWinds, Inc. and certain of its officers and/or directors violated the securities laws by issu[ing] materially false and misleading statements regarding
[SolarWinds, Inc.s] operations and its business and financial results and outlook and therefore misled investors by misrepresenting and failing to disclose material problems with  sales to the United States federal government
.. . .[and] problems with [its] sales management team. Because this lawsuit is in its initial stage, it is not possible to reliably predict the outcome of the litigation. Therefore, we cannot estimate the loss, if any, associated with
the litigation. We intend to contest the claims associated with this lawsuit vigorously. We believe that the claims asserted have no merit.

As each of these matters is in an early stage, we are currently unable to determine if the resolution of these matters will have an adverse effect on our financial position, liquidity or results of
operations. We currently have no other material legal proceedings pending other than the matters described above.

Other

We entered into an agreement to purchase certain assets of Tek-Tools in January 2010. The purchase agreement included
two earnout payments as follows: (i) up to $2.0 million of cash to be paid upon the achievement of sales milestones for 2010 and (ii) up to $2.0 million of cash to be paid upon the receipt of certain third-party consents. The
$1.9 million present value of the sales milestone earnout is based on the weighted average cost of capital discount rate reduced by the risk of achieving a sales-based milestone. The payments are recorded at fair value on our condensed
consolidated balance sheet at September 30, 2010 as an accrued acquisition earnout of $3.9 million in the aggregate. As of September 30, 2010, there have been no changes in either of the probabilities of the potential outcomes
for these payments from those ascribed at the time of acquisition as we still believe that there is a substantial likelihood that these payments will be made.

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

This section should be read in conjunction with the Condensed Consolidated Financial Statements and related notes thereto included
elsewhere in this quarterly report on Form 10-Q. This discussion contains forward-looking statements. Please see the Safe Harbor Cautionary Statement above for a discussion of the uncertainties, risks and assumptions associated with
these statements.

Overview

We design, develop, market, sell and support powerful yet easy-to-use enterprise IT management software to IT professionals in organizations of all sizes. Our offerings range from individual software
tools to more comprehensive software products that solve problems faced every day by IT professionals and help to enable efficient and effective management of networks and IT environments.

Since our founding we have provided tools for network engineers and software for managing enterprise networks, and we are a leading
provider of network management software. In 2008, with the launch of Orion Application Performance Manager, we began to offer solutions for managing servers and applications. In January 2010, in response to changes in the technology environment and
to meet the needs of our customers, we acquired certain assets of Tek-Tools, Inc., or Tek-Tools, expanding the range of elements of IT infrastructure that our products monitor and manage to include storage and virtualized servers. We now offer a
suite of powerful software that allows IT professionals to manage key elements of their infrastructure, including networks, applications, storage, and physical and virtual servers. All of our products are ready-to-use, featuring intuitive and easily
customized user interfaces and built-in workflows. Our products can be downloaded directly from our websites and installed and configured by our end-users in a matter of hours. We design our software to meet the requirements of networks and IT
environments of varying sizes and levels of complexity, ranging from a single device to over 100,000 installed devices.

We
have increased the number of our customers from over 28,000 as of June 30, 2006, to over 97,000 as of September 30, 2010. Our customers include small- and mid-size businesses, enterprises, and local, state and federal government entities
that have purchased one or more of our products. We have an active, loyal end-user community that is built from our customers and end-users who have downloaded our free tools. We seek to expand, and generate loyalty from, our customer base and our
end-user community by providing a variety of free tools for IT professionals, by hosting our online community website, thwack, and through other marketing programs.

As a core part of our strategy, we have developed a differentiated business model for marketing and selling high volumes of affordably priced, downloadable, enterprise-class software directly to IT
professionals. We design our products to be easy-to-install and easy-to-evaluate, allowing potential buyers of our software to see the value that the product provides after downloading a free copy of the software from our website for evaluation. We
design our Internet-based marketing programs to drive visitors to our websites in order to generate large volumes of highly qualified leads. Our inside sales force uses a disciplined, transaction-oriented process to convert these leads into paying
customers at a level of productivity per sales representative that is much higher than is typically achieved with a traditional direct sales force. Our business model allows us to offer our products at prices that are typically lower than competing
frameworks and to support rapid growth in our business while maintaining high operating margins. Our trailing 12-month average transaction size for new sales, excluding our Kiwi products, in each quarter during 2008, 2009 and the nine months ended
September 30, 2010, was less than $8,100.

In addition, we employ
a highly efficient product development process, a scalable marketing model and a high-volume, transaction-oriented inside sales model that have allowed us to drive and support rapid growth in our business at high operating margins while offering our
products at prices that are typically significantly lower than competing frameworks. Our revenue grew from $61.7 million in 2007 to $93.1 million in 2008 to $116.4 million in 2009 and our operating income grew from $30.9 million in
2007 to $42.0 million in 2008 to $43.8 million in 2009. We manage our business with a culture and systems that are focused on metrics and helping us to achieve consistency in our execution.

We have also sought to expand our product offerings through acquisitions. In April 2007, we acquired ipMonitor, our entry-level network
monitoring product, by purchasing substantially all of the assets and liabilities of IPMonitor Corporation, or IPMonitor. In May 2007, we acquired our LANsurveyor product and various underlying technologies by purchasing all of the outstanding stock
of Neon Software, Inc., or Neon. In December 2008, we acquired our Kiwi Syslog Server and Kiwi CatTools products by purchasing substantially all of the assets and liabilities of Trilenium Investments Limited, or Trilenium, and assets and liabilities
of its sole member. In January 2010, we acquired our Storage Profiler, Virtual and Server Profiler and Backup Profiler products in our Tek-Tools acquisition. We anticipate continuing to make selective acquisitions of companies with products that
complement our business model.

To increase our international sales, we have expanded international operations by building a
direct inside sales force and building a network of resellers in selected international markets. We established operations in Cork, Ireland in 2007 to serve as our Europe, Middle East and African, or EMEA, sales and support center as well as our
international headquarters and then opened a sales and support operation in Singapore in 2008. We have also expanded our research and development operations internationally by establishing a research and development facility in the Czech Republic in
2008 and acquiring research and development personnel in New Zealand and India. We anticipate continuing our international expansion to further market, sell and develop our products.

In May 2009, we completed our initial public offering, or IPO, in which we issued and sold 9,000,000 shares of our common stock at a
price of $12.50 per share. We raised a total of $112.5 million in gross proceeds from the offering, or approximately $100.5 million in net proceeds after deducting underwriting discounts and commissions of $7.9 million and other offering costs of
$4.1 million. In addition, we facilitated a secondary offering in November 2009, for 13,800,000 shares of common stock held by our pre-IPO major investors. The selling stockholders received all proceeds from the secondary offering. In May 2010, we
fully repaid the last of the principal outstanding under our $110.0 million credit facility that we entered into in December 2005. In August 2010, we completed a share repurchase program in which we repurchased 1.7 million shares of our
common stock at an aggregate purchase price of approximately $25.0 million.

Key Business Metrics

We designed our business model to sell high volumes of low-priced, downloadable, enterprise-class software to our customers and to be low
cost, scalable and efficient. We review a number of key business metrics to help us monitor the performance of our business model and to identify trends affecting our business. The measures that we believe are the primary indicators of our quarterly
and annual performance are as follows:

Average Transaction Size for New Sales. We focus our sales, marketing and
research and development efforts on IT professionals in organizations of all sizes, with the goal of driving purchases of our software by these IT professionals in very short sales cycles with minimal levels of approval. In addition, many of our
customers make small initial purchases of our software to manage specific components of their networks and then make additional purchases over time to expand the use of the product that they purchased or to buy additional software products from us.
We measure the average transaction size for new sales on a frequent

##### Table of Contents

basis as an indicator of the success of these efforts and to ensure the effectiveness of our marketing and sales model. We define a transaction as each invoice issued for the sale of one or more
of our products. We exclude our Kiwi Syslog Server and Kiwi CatTools products from our calculation of average transaction size for new sales because these products sell at a much lower price point than our Orion family of products and, despite
representing a small portion of our revenue, would therefore have a significant impact on the average transaction size for new sales in those periods in which we sold the products. By excluding our Kiwi products, we believe that management can
better evaluate our core business without the variations imposed by the Kiwi products. Since the average transaction size for new sales will fluctuate on a quarterly basis as a result of a different mix of business and product sales,
especially our U.S. federal government business, we also review the average transaction size for new sales on a trailing 12- month basis to eliminate the quarterly variability in our transaction mix.

Non-GAAP Operating Income. Our management uses non-GAAP operating income to measure our performance. Because non-GAAP operating
income excludes certain non-cash expenses such as amortization, stock-based compensation and certain expenses that may not be indicative of our core business, we believe that this measure provides us with additional useful information to measure and
understand our performance on a consistent basis, particularly with respect to changes in performance from period to period. We use non-GAAP operating income in the preparation of our budgets and to measure and monitor our performance. Non-GAAP
operating income is not determined in accordance with GAAP and is not a substitute for, or superior to, financial measures determined in accordance with GAAP. For further discussion regarding non-GAAP operating income and a reconciliation of
non-GAAP operating income to net income, see Reconciliation of Non-GAAP Financial Measures included later in this Item 2 entitled Managements Discussion and Analysis of Financial Condition and Results of
Operations.

Revenue Growth.
We have employed a differentiated business model for marketing and selling high volumes of enterprise-class software, which is focused on rapid revenue growth at high operating margins. We regularly review our total revenue growth to measure our
success. We have built a pricing model for our products that aims to maximize our recurring revenue and the value of a customer over time and not upfront license revenue. This is an important component of our financial model. This model is based on
the premise that we will be able to deliver ongoing value to our customers and maintain a long-term financial relationship with the users of our core enterprise-class network and IT management products.

Opportunities and Trends

Businesses, governments and other organizations are increasingly relying on data networks and IT infrastructures to execute their operations, facilitate their internal and external communications and
transact business with their customers and partners. The size of these networks, the number of applications and servers, and the complexity of physical and virtual server environments are increasing as organizations place more reliance on them. We
believe that the increasing challenges of IT management and the limitations of existing offerings present a market opportunity for our products. In addition to the network management products that we have offered since 2001, we also offer products
that we have developed or acquired that manage servers and applications and monitor and manage storage and virtualized servers. We believe that these products allow us to compete effectively in the adjacent markets of application management,
storage resource management and virtual server management. We expect our revenue to continue to grow as we capitalize on these and other market opportunities.

We expect our trailing 12-month average transaction size for new sales to increase in the 15-20% range over the next several quarters as we anticipate increasing our sales to enterprise customers who
tend to enter into larger transactions and continue to pursue our strategy of offering standalone products as well as attaching more modules to the sales of our flagship product, Orion Network Performance Monitor, or Orion NPM. In
addition, sales of the storage and virtualization products we acquired from Tek-Tools will also contribute to this growth as the average transaction size for new sales on these products is currently higher than our Orion family of
products.

Recent statistics indicate that the United States and certain other international economies are showing some signs
of stabilization. A larger number of current and potential customers seem to be more confident in making purchases of IT software and we expect that confidence to continue into the future and we hope to capitalize on this
opportunity. However, we believe there remains significant uncertainty regarding the extent and timing of an economic recovery in certain geographic regions. In these regions, we believe that difficult economic conditions offer us an
opportunity to market and sell our products to mid-size businesses and enterprise customers at compelling prices compared to the prices of many competing products.

We expect the U.S. federal government to continue to be a significant market opportunity as we believe the ease of deployment, power and scalability of our products give us an enhanced opportunity to sell
to various agencies and departments of the U.S. federal government. Prior to the third quarter of 2010, our new sales to the U.S. federal government had declined over the prior three quarters due to a reduction in the value of orders received
from agencies and groups associated with the Department of Defense. In the third quarter of 2010, our new sales to the U.S. federal government were the second highest in our history and increased significantly over these prior quarters. This
increase over the prior three quarters was due to, among other things, a greater number of large, project-based transactions that closed in the third quarter of 2010, a few of which we had expected to close earlier in 2010. We continue to
expect inconsistency in the buying pattern of the U.S. federal government for these larger transactions with our products. In addition, our sales to the U.S. federal government are largely dependent on systems integrators, distributors and
resellers whose purchases from us have been difficult to predict. We may, therefore, be unable to predict accurately when and if the purchase orders from the U.S. federal government will be received.

We expect to continue
to invest for the foreseeable future in expanding our business as we increase our direct inside sales presence in the United States, Europe and Asia, enhance and expand our product offerings and pursue strategic acquisitions. We expect to continue
to experience significant annual growth in our commercial business while striving to maintain non-GAAP operating income as a percentage of revenue; however, there is a risk that the returns that we achieve on future investments in the growth of our
business will not be as rapid or as high as what we have achieved in the past.

We expect our revenue to increase from the
Tek-Tools acquisition in January 2010, but expect the acquired business to have a negative impact on our overall non-GAAP operating income as a percentage of revenue. We expect that this negative impact on non-GAAP operating income as a
percentage of revenue to continue through the end of 2010.

Key Components of Our Results of Operations

Sources of Revenue

Our revenue is primarily comprised of license and maintenance revenue. We license our software under perpetual licenses, which includes maintenance, typically for one year, as part of the initial purchase
price of the product. License revenue reflects the revenue recognized from sales of new licenses and upgrades to our software. We have experienced annual growth in license revenue. Customers can renew and generally have renewed their maintenance
agreements for annual periods at our standard list maintenance renewal pricing for their software products. Current customers with maintenance agreements are entitled to receive unspecified upgrades or enhancements when and if they become available.
Maintenance revenue is an important source of our future revenue. We have experienced strong and consistent annual and quarterly growth in maintenance and other revenue. Because our maintenance base grew during 2009 and the first three quarters of
2010 due to new sales and high customer retention, we expect maintenance revenue to continue to increase in future periods.

Cost of Revenue

Cost of revenue consists of personnel costs related to providing technical support services, amortization of acquired developed product technologies and amortization of capitalized software costs.
Personnel costs include salaries, bonuses and stock-based compensation for technical support personnel, as well as an allocation of our facilities, information technology and other overhead costs and our employee benefit costs. We allocate
stock-based compensation expense to personnel costs based on the expense category in which the option holder works. We allocate overhead, such as rent, computer and other technology costs, and employee benefit costs to personnel costs in each
expense category based on worldwide headcount in that category. We expect our cost of revenue to increase in absolute dollars but to remain relatively stable as a percentage of revenue in future periods.

Operating Expenses

We classify our operating expenses into three categories: sales and marketing, research and development and general and administrative.

Our operating expenses primarily consist of personnel costs, contract research and development costs, marketing program costs and legal,
accounting, consulting and other professional service fees. Personnel costs for each category of operating expenses include salaries, bonuses and stock-based compensation for personnel in that category, as well as an allocation of our facilities,
information technology and other overhead costs and our employee benefit costs. We allocate stock-based compensation expense resulting from the amortization of the fair value of options granted based on how we categorize the department in which the
optionholder works. We allocate overhead, such as rent, computer and other technology costs and employee benefit costs, to each expense category based on worldwide headcount in that category.

In 2009 and 2010, we
have continued to build infrastructure and add employees through acquisitions and internal growth across all departments in order to accelerate and support our growth and to expand into international markets. Due to this, our operating expenses have
increased as a percentage of revenue and in absolute dollars in the three and nine months ended September 30, 2010 compared to the same periods in 2009. The number of employees as of September 30, 2010 was 433 as compared to 303 as of
September 30, 2009. We expect our operating expenses in future periods to continue to increase in absolute dollars and, to be higher as a percentage of revenue if we acquire additional companies and as we integrate the businesses.

Sales and Marketing. Sales and marketing expenses primarily consist of personnel costs for our sales, marketing and business
development employees and executives, commissions earned by our sales personnel, the cost of marketing programs such as on-line lead generation, promotional events and webinars and the cost of business development programs. We expect to continue to
hire sales personnel in the United States and in both of our international offices.

Research and Development. Research
and development expenses primarily consist of personnel costs for our product development employees and executives and fees to our contract development vendors in Eastern Europe. We have devoted our development efforts primarily to expanding our
product line and increasing the functionality and enhancing the ease-of-use of our software offerings. In 2008, we opened a development center in the Czech Republic to take advantage of low labor rates and strong technical talent. We also acquired
research and development personnel in New Zealand and India as part of our acquisition of Trilenium and Tek-Tools, respectively. Since establishing our research and development center in the Czech Republic and as a result of our acquisitions, we
have significantly increased our research and development employee headcount and relied less on our Eastern European contract development vendors for research and development personnel. We expect to continue to invest in our research and development
activities by hiring engineers in the U.S. and in our foreign subsidiaries.

General and Administrative. General
and administrative expenses primarily consist of personnel costs for our executive, finance, legal, human resources and administrative personnel, as well as legal, accounting and other professional service fees and other corporate expenses. We
incurred additional costs in 2009 and the first three quarters of 2010 and expect to continue to incur higher costs associated with being a public company, including higher legal, corporate insurance and financial reporting expenses and the
additional costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act.

Other Income
(Expense).Other income (expense) primarily consists of interest income, interest expense, foreign exchange gains (losses) and government grant income. Interest income represents interest received on our cash and cash equivalents. Interest
expense is associated with our outstanding long-term debt, the outstanding principal of which was $44.1 million on December 31, 2009 and was paid in full on May 28, 2010. Interest expense includes the amortization and write-off of
debt issuance costs, which was $0 and $51,000 for the three months ended September 30, 2010 and 2009, respectively, and $0.4 million and $0.7 million in the nine months ended September 30, 2010 and 2009, respectively. Foreign exchange
gains (losses) relate to expenses and transactions denominated in currencies other than the functional currency of the associated company. Government grant income relates to grants to be received by our Irish and Czech Republic entities for the
creation of job positions and related training costs.

Income Tax Expense

Income tax expense primarily consists of corporate income taxes related to profits resulting from the sale of our software offerings by
our United States and Irish entities. We expect our income tax expense to increase in absolute dollars as our profits continue to increase; however, we expect our effective tax rate to decline slowly, due to the lower corporate tax rate in Ireland,
as our international revenue increases as a percentage of total revenue.

##### Table of Contents



We benefit from the
tax credit incentives under the U.S. research and experimentation tax credit extended to taxpayers engaged in qualified research and experimental activities while carrying on a trade or business. The tax credit expired on December 31, 2009, and
as such, no benefit is reflected in our income tax expense for the three months and nine months ended September 30, 2010. If this tax credit is not renewed under similar terms as in prior years, our effective tax rate will be higher
than if it was renewed and may be higher than the rate in the prior comparable period.

Critical Accounting Policies and
Estimates

We prepare our condensed consolidated financial statements in accordance with GAAP. The preparation of condensed
consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. We base our estimates on historical experience and on
various other assumptions that we believe to be reasonable under the circumstances. In many instances, we could reasonably use different accounting estimates, and in some instances changes in the accounting estimates are reasonably likely to occur
from period to period. Accordingly, actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation,
financial condition, results of operations and cash flows will be affected.

In many cases, the accounting treatment of a
particular transaction is specifically dictated by GAAP and does not require managements judgment in its application, while in other cases, managements judgment is required in selecting among available alternative accounting standards
that allow different accounting treatment for similar transactions. We believe that these accounting policies requiring significant management judgment are critical to understanding our historical and future performance, as these policies relate to
the more significant areas involving managements judgments and estimates. These critical accounting policies are:



| |  |  | Impairment of long-lived assets;
| | - |  | --------------------------------



| |  |  | Goodwill and other intangible assets with indefinite lives;
| | - |  | -----------------------------------------------------------



| |  |  | Revenue recognition;
| | - |  | --------------------



| |  |  | Stock-based compensation; and
| | - |  | -----------------------------



| |  |  | Income taxes.
| | - |  | -------------

A description of our critical accounting policies that involve significant management judgments appears in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 filed with
the Securities and Exchange Commission under the heading Managements Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting Policies and Estimates.

Comparison of the Three Months Ended September 30, 2010 and 2009

Revenue

Revenue was $41.2 million in the three months ended September 30, 2010 compared to $32.4 million in the three months ended
September 30, 2009, an increase of $8.8 million, or 27.2%. This increase was comprised of a $5.6 million increase in maintenance and other revenue, which resulted from a growing maintenance base due to new sales, new customers through
acquisitions and high customer retention, and a $3.2 million increase in license revenue due to an increase in sales transaction volumes of our core enterprise -class network and IT management products and a 24.6% increase in our trailing
12-month average transaction size for new sales. Through the third quarter of 2010, the trailing 12-month average transaction size for new sales was approximately $8,100 as compared to approximately $6,500 for the 12-month period through
the third quarter of 2009. We believe that the increase in new sales and our average transaction size for new sales resulted from better awareness of our products, an increase in the number of products that we sell primarily as a result of our
product development and, to a significantly lesser extent, our acquisitions.

New sales in our commercial business increased
29.9% globally while new sales in our U.S. federal government business decreased 7.2% for the third quarter of 2010 compared to the third quarter of 2009. The decline in U.S. federal sales was primarily driven by a reduction in the value of orders
received from agencies and groups associated with the Department of Defense. We received one purchase order in the third quarter of 2010 and two purchase orders in the third quarter of 2009 from the federal business that resulted in license
revenue greater than $0.5 million. Our revenue results also had a negative impact from foreign currency rates during the third quarter of 2010 compared to the rates during the third quarter of 2009. Our international revenue was 19.8% and 18.0% of
total revenue in the third quarter of 2010 and 2009, respectively. If we applied the exchange rate used in the third quarter of 2009 to revenue in the third quarter of 2010, the net negative impact is $0.9 million, comprised of an impact on license
and maintenance revenue of $0.5 million and $0.4 million, respectively.

Cost of Revenue

Cost of revenue was $2.0 million in the three months ended September 30, 2010 compared to $1.3 million in the three months ended
September 30, 2009, an increase of $0.8 million, or 61.3%. This increase was primarily due to a $0.4 million increase in cost of maintenance revenue related to increased headcount in

our North American, European and Asian-Pacific support organizations to support the new customers we added during 2009 and the first three quarters of 2010. Cost of license revenue also increased
by $0.3 million in the three months ended September 30, 2010 compared to the same period in 2009 primarily due to the amortization of acquired product technologies associated with the Tek-Tools acquisition in January 2010.

Operating Expenses

Sales and Marketing. Sales and marketing expenses were $11.0 million in the three months ended September 30, 2010 compared to $7.8 million in the three months ended September 30,
2009, an increase of $3.2 million, or 41.6%. Sales and marketing expenses increased in the three months ended September 30, 2010 due to the expansion of our direct inside sales force in the United States, EMEA and Asian-Pacific region, an
increase in marketing operations and program costs in the United States and EMEA and an increase in business development costs as we began to expand our partner relationships. As a result of these efforts, our sales and marketing personnel costs,
which include stock-based compensation expense, increased by $1.8 million. Marketing program costs to drive higher levels of web traffic such as paid search, search engine optimization, search engine management, web operating costs and trade
shows increased by $1.1 million. Other costs such as professional fees and consulting services increased by $0.3 million.

Research and Development. Research and development expenses were $4.1 million in the three months ended September 30, 2010
compared to $3.0 million in the three months ended September 30, 2009, an increase of $1.1 million, or 35.8%. In order to support our product development strategy, we continued to increase the size of our Czech Republic research center from the
third quarter of 2009 to 2010 and also added research and development personnel in Dallas, Texas and Chennai, India in 2010 as a result of the acquisition of Tek-Tools. Due to this growth, our personnel costs, which include stock-based compensation
expense, increased by $1.1 million in the third quarter of 2010 compared to the third quarter of 2009.

General and
Administrative.General and administrative expenses were $5.9 million in the three months ended September 30, 2010 compared to $5.2 million in the three months ended September 30, 2009, an increase of $0.7 million, or 13.8%.
This increase was due primarily to an increase of $0.9 million in personnel costs, which include stock-based compensation expense, $0.3 million in amortization related to certain intangible assets from Tek-Tools partially offset by a
$0.7 million decrease as we incurred lawsuit settlement and related legal fees in 2009.

Other Income (Expense)

Interest expense in the three months ended September 30, 2010 decreased by $0.7 million from the three months ended
September 30, 2009 due to no outstanding debt in the third quarter of 2010 because of principal payments made in 2009 and 2010. The outstanding principal balance under our indebtedness was as follows at:

Our outstanding
principal balance on the Notes was $44.1 million as of September 30, 2009. In March 2010, we prepaid $19.1 million of principal to repay all of the outstanding principal balance on the First Lien Note. In May 2010, we
fully repaid the remaining $25.0 million of principal outstanding on the Second Lien Note.

Other income (expense) includes a
$0.2 million increase in the fair value of the accrued acquisition earnout and $0.3 million of foreign exchange losses offset by $0.3 million of government grant income from our Czech and Irish entities for the creation of job positions and related
training costs as of September 30, 2010.

Income Tax Expense

Our income tax expense increased by $1.5 million for the three months ended September 30, 2010 compared to the same
period for 2009. This increase resulted from an increase in our income before income taxes of $3.5 million during the same period. Our expected effective tax rate increased from 30.1% in the three months ended September 30, 2009 to 32.7%
in the three months ended September 30, 2010 primarily as a result of the non-renewal of the U.S. federal research and experimentation tax credit.

The following table sets forth our condensed consolidated statements of income data for the periods indicated (in thousands):

Comparison of the Nine Months Ended September 30, 2010 and 2009

Revenue

Revenue was $111.0 million in the nine months ended September 30, 2010 compared to $83.5 million in the nine months ended
September 30, 2009, an increase of $27.5 million, or 33.0%. This increase was comprised of a $16.6 million increase in maintenance and other revenue, which resulted from a growing maintenance base due to new sales, new maintenance customers
through acquisitions and high customer retention, and an $11.0 million increase in license revenue, which was due to an increase in sales transaction volumes of our core enterprise-class network and IT management products and a 24.6%
increase in our trailing 12-month average transaction size for new sales. Through the third quarter 2010, the trailing 12-month average transaction size for new sales was approximately $8,100 as compared to approximately $6,500 for
the 12-month period through the third quarter of 2009. We believe that the increase in new sales and our average transaction size for new sales resulted from better awareness of our products, an increase in the number of products that we
sell primarily as a result of our product development and, to a significantly lesser extent, our acquisitions.

New sales in our
commercial business increased 36.9% globally while new sales in our U.S. federal business decreased 14.6% for the first three quarters of 2010 compared to the first three quarters of 2009. The decline in U.S. federal government sales was primarily
driven by a reduction in the value of orders received from agencies and groups associated with the Department of Defense. We received two purchase orders in the nine months ended September 30, 2010 and six purchase orders in the nine months
ended September 30, 2009 from the federal business that resulted in license revenue greater than $0.5 million. To a lesser extent, our revenue results also had a negative impact from foreign currency rates during the first three quarters of
2010 compared to the rates during the first three quarters of 2009. Our international revenue was 21.0% and 19.0% of total revenue in the first three quarters of 2010 and 2009, respectively. If we applied the exchange rate used in the first three
quarters of 2009 to revenue in the first three quarters of 2010, the net negative impact is $1.1 million, comprised of an impact on license and maintenance revenue of $0.6 million and $0.5 million, respectively.

Cost of Revenue

Cost of revenue was $5.7 million in the nine months ended September 30, 2010 compared to $3.6 million in the nine months ended September 30, 2009, an increase of $2.1 million, or 57.8%.
This increase was primarily due to a $1.3 million increase in cost of maintenance revenue related to increased headcount of our North American, European and Asian-Pacific support organizations to support the new customers we added
during 2009 and the first three quarters of 2010. Cost of license revenue also increased by $0.8 million in the nine months ended September 30, 2010 compared to the same period in 2009 primarily due to the amortization of acquired product
technologies associated with the Tek-Tools acquisition in January 2010.

Operating Expenses

Sales and Marketing. Sales and marketing expenses were $31.9 million in the nine months ended September 30, 2010 compared to
$21.7 million in the nine months ended September 30, 2009, an increase of $10.2 million, or 47.2%. Sales and marketing expenses increased in the nine months ended September 30, 2010 due to the expansion of our direct inside sales
force in the United States, EMEA and Asian-Pacific region, an increase in marketing operations and program costs in the United States and EMEA and increased headcount as a result of acquisitions. As a result of these efforts, our sales and
marketing personnel costs, which include stock-based compensation expense, increased by $6.5 million. Marketing program costs such as paid search, search engine optimization, search engine management, web operating costs and trade shows
increased by $2.9 million. Other costs such as professional fees, subscription costs, and consulting services increased $0.6 million.

Research and Development. Research and development expenses were $11.5 million in the nine months ended September 30, 2010 compared to $8.2 million in the nine months ended September 30,
2009, an increase of $3.3 million, or 40.9%. In order to support our product development strategy, we increased the size of our research and development organization in 2009 and 2010, including a significant increase to our personnel in our
Czech Republic development center as well as the addition of research and development personnel in Dallas, Texas and Chennai, India as a result of the acquisition of Tek-Tools. Due to this growth, our personnel costs, which include stock-based
compensation expense, increased by $3.3 million in the first three quarters of 2010 compared to the first three quarters of 2009.

General and Administrative. General and administrative expenses were $18.1 million in the nine months ended September 30, 2010 compared to $13.1 million in the nine months ended
September 30, 2009, an increase of $5.0 million, or 37.9%. This increase was due primarily to an increase of $4.1 million in personnel costs, which include stock-based compensation expense, $0.9 million in amortization related to
certain intangible assets from Tek-Tools, $0.4 million in accounting and legal costs associated with the acquisition of

Tek-Tools offset by a $0.7 million decrease in legal expenses as we incurred lawsuit settlement and related legal fees in 2009. The increase in stock-based compensation expense of $2.2
million included a one-time expense of $1.4 million from the acceleration of the vesting of certain options related to the retirement of our former Executive Chairman on June 30, 2010.

Other Income (Expense)

Interest expense in the nine months ended September 30, 2010 decreased by $2.5 million from the nine months ended September 30, 2009 due to a lower amount of outstanding indebtedness because of
principal payments we made in 2009 and 2010. The outstanding principal balance under our indebtedness was as follows at:

In the second quarter
of 2009, we repaid an additional $49.8 million of principal with the net proceeds from our IPO in May 2009, reducing our outstanding principal balance on the Notes to $44.1 million as of September 30, 2009. In March 2010, we repaid
$19.1 million of principal to repay all of the outstanding principal balance on the First Lien Note. In May 2010, we fully repaid the remaining $25.0 million of principal outstanding on the Second Lien Note.

Other income (expense) includes a $0.2 million increase in the fair value of the accrued acquisition earnout and $0.1 million of
foreign exchange losses offset by $0.3 million of government grant income from our Czech and Irish entities for the creation of job positions and related training costs as of September 30, 2010.

Income Tax Expense

Our income tax expense increased by $3.0 million for the nine months ended September 30, 2010 compared to the same period for 2009. This increase resulted from an increase in our income before income
taxes of $9.4 million during the same period. Our expected effective tax rate increased from 31.2% in the nine months ended September 30, 2009 to 31.3% in the nine months ended September 30, 2010 primarily as a result of the
non-renewal of the U.S. federal research and experimentation tax credit.

Reconciliation of Non-GAAP Financial Measures

Our investor and analyst presentations include non-GAAP operating income, which we define as operating income plus
stock-based compensation expense and related employer-paid payroll taxes, amortization of intangible assets, expenses related to the potential and completed public offerings of common stock, lawsuit settlement and related legal fees, certain
acquisition related costs and severance costs related to the retirement of our former Executive Chairman. The table below provides a reconciliation of this non-GAAP financial measure to the most recent directly comparable financial measure
calculated and presented in accordance with GAAP. Non-GAAP operating income should not be considered as an alternative to operating income and any other measure of financial performance calculated and presented in accordance with GAAP. Our non-GAAP
operating income may not be comparable to similarly titled measures of other organizations because other organizations may not calculate non-GAAP operating income in the same manner as we do. We prepare non-GAAP operating income to eliminate the
impact of items that we do not consider indicative of our core operating performance. You are encouraged to evaluate these adjustments and the reasons we consider them appropriate.

##### Table of Contents



We believe non-GAAP
operating income is useful to investors in evaluating our operating performance for the following reasons:



| |  |  | Non-GAAP operating income is widely used by investors to measure a companys operating performance without regard to items, such as
interest expense, income tax expense, depreciation and amortization and stock-based compensation and related employer-paid payroll taxes, that can vary substantially from company to company depending upon their financing and accounting methods, the
book value of their assets, their capital structures and the method by which their assets were acquired and certain expenses and expenditures, such as lawsuit settlement and related legal fees, that may not be indicative of a companys core
business operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Securities analysts use non-GAAP operating income as a supplemental measure to evaluate the overall operating performance of companies; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | By comparing our non-GAAP operating income in different historical periods, our investors can evaluate our operating results without the
additional variations of stock-based compensation expense, which is a non-cash expense that is not a key measure of our operations.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our management uses non-GAAP operating income:



| |  |  | As a measure of operating performance, because it does not include the impact of items not directly resulting from our core operations;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For planning purposes, including the preparation of our annual operating budget;
| | - |  | --------------------------------------------------------------------------------



| |  |  | To allocate resources to enhance the financial performance of our business;
| | - |  | ---------------------------------------------------------------------------



| |  |  | To evaluate the effectiveness of our business strategies; and
| | - |  | -------------------------------------------------------------



| |  |  | In communications with our board of directors concerning our financial performance.
| | - |  | -----------------------------------------------------------------------------------

We understand that, although non-GAAP operating income is frequently used by investors and securities analysts in their evaluation of
companies, non-GAAP operating income has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results of operations as reported under GAAP. Items excluded from the calculation of
non-GAAP operating income, such as stock-based compensation expense and related employer-paid payroll taxes, the amortization of intangible assets, costs related to equity offerings, acquisition-related costs and severance costs related to the
retirement of our former Executive Chairman, can have a material impact on our business.

The following table presents a
reconciliation of non-GAAP operating income to operating income, the most comparable GAAP measure, for each of the periods indicated (in thousands):

Acquisitions

On January 26, 2010, we acquired certain of the assets of Tek-Tools for the following: (i) $26.0 million of
cash; (ii) 362,138 shares of our common stock with a value of approximately $7.4 million based on the closing price of our common stock as reported on the New York Stock Exchange on January 26, 2010; (iii) $2.0 million of cash and
90,535 shares of our common stock with a value of approximately $1.8 million based on the closing price of our common stock on the date of the acquisition, each being held in escrow as security for breaches of representations and warranties,
covenants and certain other expressly enumerated matters by Tek-Tools and its stockholders; (iv) $2.0 million of cash being withheld to be paid upon the achievement of sales milestones of the acquired business during calendar year 2010; and
(v) $2.0 million of cash being withheld to be paid upon the receipt of certain third-party consents. Tek-Tools provided us an immediate product offering of storage and virtualized server infrastructures that was missing from our product
offerings and eliminated the normal time to market required to develop a new software product. We accounted for the Tek-Tools acquisition using the purchase method of accounting. We allocated the purchase price to the assets acquired, including
intangible assets, and liabilities assumed based on estimated fair values at the date of the acquisition. We estimated the value of assets and liabilities based on purchase price and future intended use. We derived the value of intangible assets of
$18.1 million and recorded goodwill of $25.2 million for the Tek-Tools acquisition. We derived the value of intangible assets from the present value of estimated future benefits from the various intangible assets acquired. Goodwill represents the
excess of the purchase price over the aggregate fair value of the net identifiable assets acquired. We have included the operating results of this acquisition in our consolidated results from the effective date of the acquisition.

Liquidity and Capital Resources

At September 30, 2010, we had $107.8 million in cash and cash equivalents and $77.8 million of working capital. Our available cash and cash equivalents are held in bank deposits and money market
funds. Our money market mutual funds invest in high-quality, short-term securities, many of which are issued or guaranteed by the U.S. government or by U.S. government agencies. We also hold a portion of our cash and cash equivalents in bank
deposits located in Ireland that are fully guaranteed by the Irish government. We actively monitor the third-party depository institutions that hold our cash and cash equivalents. Our emphasis is primarily on safety of principal while secondarily
maximizing yield on those funds. The balances held in the United States may exceed the Federal Deposit Insurance Corporation, or FDIC, insurance limits or may not be insured by the FDIC. While we monitor the balances in our accounts
and adjust the balances as appropriate, these balances could be impacted if the underlying depository institutions or the guarantors fail or could be subject to adverse conditions in the financial markets. We strive to maintain our cash deposits and
invest our money market funds with financial institutions of reputable credit and therefore bear minimal credit risk. To date, we have experienced no loss or lack of access to our invested cash and cash equivalents; however, we can provide no
assurances that access to our funds will not be impacted by adverse conditions in the financial markets.

As of
December 31, 2009, we had approximately $44.1 million of outstanding indebtedness under our First Lien and Second Lien Notes. In March 2010, we made a required prepayment of $16.9 million and an additional prepayment of $2.2 million of
principal, which paid off the entire outstanding principal under our First Lien Note and reduced our total outstanding indebtedness to $25.0 million under our Second Lien Note. In May 2010, we fully repaid the $25.0 million of principal outstanding
on the Second Lien Note. Upon payment of the Second Lien Note, we are no longer subject to the restrictive covenants of the Notes.

We estimate our capital expenditures for 2010 to be approximately $2.5 million, comprised primarily of additional leasehold improvements, furniture and fixtures and computer equipment.

Operating
Activities

Net cash provided by operating activities was $46.0 million and $36.0 million for the nine months ended
September 30, 2010 and 2009, respectively. Net income was $29.4 million and $23.0 million for the nine months ended September 30, 2010 and 2009, respectively. We had a net non-cash benefit of $3.3 million and incurred non-cash expenses of
$5.9 million for the nine months ended September 30, 2010 and 2009, respectively. Non-cash (benefits) or expenses primarily consisted of stock-based compensation expense of $9.0 million and $5.6 million, excess tax benefits related to employee
stock option exercises of $(17.4) million and $(2.2) million and depreciation and amortization expense of $3.9 million and $1.6 million for the nine months ended September 30, 2010 and 2009, respectively.

The change in certain assets and liabilities resulted in a net source of cash of $19.9 million and $7.2 million for the nine months
ended September 30, 2010 and 2009, respectively. Cash provided by operating activities is driven by sales of our software offerings and maintenance renewals. Collection of accounts receivable from the sales of our software offerings and
maintenance renewals is a significant component of our cash flows from operating activities, as is the change in deferred revenue related to these sales. Net cash provided by operating activities was reduced by interest payments of $1.3 million
and $4.4 million for the nine months ended September 30, 2010 and 2009, respectively. Net cash provided by operating activities was increased by $3.5 million which included an income tax refund in the nine months ended September 30, 2010
that decreased prepaid income taxes.

Investing Activities

Net cash used in investing activities was $30.7 million and $2.2 million for the nine months ended September 30, 2010 and 2009,
respectively. Net cash used in investing activities for the nine months ended September 30, 2010 was primarily due to the $28.0 million of cash used in our purchase of certain assets of Tek-Tools and $2.0 million of purchases of property and
equipment for operations.

Financing Activities

Net cash used in financing activities was $37.0 million and net cash provided by financing activities was $51.0 million for the nine months ended September 30, 2010 and 2009, respectively. Net cash
used in financing activities in the nine months ended September 30, 2010 was due to a $44.1 million repayment of long-term debt partially offset by $14.8 million of proceeds from the exercise of stock options and a $17.4 million excess tax
benefit related to stock-based compensation. This excess tax benefit is a reduction in cash payments for U.S. federal income taxes due to tax deductions related to stock option exercises. On August 2, 2010, our board of directors
approved a share repurchase program, authorizing us to purchase up to $25.0 million of our outstanding common stock. We were authorized to make purchases in the open market and purchases were funded from available working capital. The share
repurchase program was completed in August 2010, and we repurchased and retired 1.7 million shares of our common stock for an aggregate purchase price of $25.0 million.

##### Table of Contents



We believe that our
existing cash and cash equivalents and our cash flow from operations will be sufficient to fund our operations and our capital expenditures for at least the next 12 months. Our future capital requirements will depend on many factors, including our
rate of revenue growth, the expansion of our sales and marketing activities, the timing and extent of spending to support product development efforts and expansion into new territories, the timing of introductions of new software products and
enhancements to existing software products, and the continuing market acceptance of our software offerings. Although we are not currently a party to any agreement or letter of intent regarding potential investments in, or acquisitions of,
complementary businesses, applications or technologies, we may enter into these types of arrangements, which could require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

Contractual Obligations and Commitments

We entered into an agreement to purchase certain assets of Tek-Tools in January 2010. The purchase agreement included two earnout payments
as follows: (i) up to $2.0 million of cash to be paid upon the achievement of sales milestones for 2010 and (ii) up to $2.0 million of cash to be paid upon the receipt of certain third-party consents. The payments are recorded at fair
value on our condensed consolidated balance sheet at September 30, 2010 as an accrued acquisition earnout of $3.9 million. We are expecting to make these payments in the first quarter of 2011.

Off-Balance Sheet Arrangements

During the nine months ended September 30, 2010, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities
that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.



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

We are exposed to certain financial market risks, the most predominant being foreign currency risk.

Interest Rate Risk

We had cash and cash equivalents of $107.8
million at September 30, 2010. We held these amounts primarily in cash or money market funds. We hold cash and cash equivalents for working capital purposes. We do not have material exposure to market risk with respect to investments, as our
investments consist primarily of highly liquid investments purchased with original maturities of three months or less. We do not use derivative financial instruments for speculative or trading purposes; however, we may adopt specific hedging
strategies in the future. Any declines in interest rates, however, will reduce future interest income.

Foreign Currency
Risk

As a global company, we face exposure to adverse movements in foreign currency exchange rates. Our international
revenue was approximately 21.0% of our total revenue for the nine months ended September 30, 2010. The primary foreign currencies that we invoice and on which we collect are the Euro and British Pound Sterling. Expenses incurred
by our international subsidiaries are generally denominated in the local currency of the subsidiary. Our consolidated statements of income are translated into U.S. dollars at the average exchange rates in each applicable period. To the
extent the U.S. dollar strengthens against foreign currencies, the translation of these foreign currency denominated transactions results in reduced revenues, operating expense, and net income for our international operations. Similarly, our
revenues, operating expenses, and net income will increase for our international operations if the U.S. dollar weakens against foreign currencies. We

##### Table of Contents

do not currently enter into forward exchange contracts to hedge exposure denominated in foreign currencies or any derivative financial instruments for trading or speculative purposes, although we
may do so in the future. Thus, fluctuations in currency exchange rates could harm our business in the future.

We are also
exposed to foreign exchange rate fluctuations as we translate the financial statements of our foreign subsidiaries into U.S. dollars in consolidation. If there is a change in foreign currency exchange rates, the conversion of the foreign
subsidiaries financial statements into U.S dollars will lead to a translation gain or loss which is recorded as a component of accumulated other comprehensive income (loss) in stockholders equity.



|Item 4: | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2010.
The term disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a
company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SECs rules and forms. Disclosure controls and procedures include, without
limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the companys management, including
its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as
of September 30, 2010, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

The SEC, as required by Section 404 of the Sarbanes-Oxley Act, adopted rules requiring every company that files reports with the SEC
to include a management report on such companys internal control over financial reporting in its annual report. In addition, our independent registered public accounting firm must attest to our internal control over financial reporting. Our
Annual Report on Form 10-K for the fiscal year ended December 31, 2009 did not include a report of managements assessment regarding internal control over financial reporting or an attestation report of our independent registered public
accounting firm due to a transition period established by SEC rules applicable to newly public companies. Management will be required to provide an assessment of the effectiveness of our internal control over financial reporting as of
December 31, 2010. We believe we have adequate resources and expertise, both internal and external, in place to meet this requirement. However, there is no guarantee that our efforts will result in managements ability to conclude, or
our independent registered public accounting firm to attest, that our internal control over financial reporting is effective as of December 31, 2010.

There were no changes in our internal control over financial reporting that occurred during the three months ended September 30, 2010, that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

PART II. OTHER
INFORMATION



|Item 1. | Legal Proceedings
|------- | -----------------

From
time to time, we have been and may be involved in various legal proceedings arising from our ordinary course of business.

On
September 13, 2010, Uniloc USA, Inc. and Uniloc (Singapore) Private Limited (Uniloc) brought a lawsuit against SolarWinds, Inc. and SolarWinds Worldwide, LLC (collectively, SolarWinds) and several other defendants in the
United States District Court for the Eastern District of Texas. The complaint filed by Uniloc alleges that SolarWinds and each of the other fifteen named defendants software infringe U.S. patent 5,490,216 allegedly owned by
Uniloc. Uniloc alleges that SolarWinds software, specifically its license key system, infringes upon this patent that utilizes a system for activating software products through a registration process. Uniloc has brought a series of
lawsuits against numerous software companies around the world and the infringement and damages related to the patent at issue in the case is currently being challenged in the United States Court of Appeals for the Federal Circuit. Because
this lawsuit is in its initial stages, it is not possible to reliably predict the outcome of the litigation. Therefore, we cannot currently estimate the loss, if any, associated with the litigation. We intend to contest the claims
associated with this lawsuit vigorously.

On October 15, 2010, a lawsuit was filed on behalf of Daniel Richardson against
SolarWinds, Inc. and certain of its current and former officers in the United States District Court for the Northern District of Texas. The lawsuit was filed on behalf of Richardson and a purported class of all persons who purchased or acquired
shares of common stock of SolarWinds, Inc. between February 8, 2010 and July 21, 2010 and alleges that SolarWinds, Inc. and certain of its officers and/or directors violated the securities laws by issu[ing] materially false and
misleading statements regarding [SolarWinds, Inc.s] operations and its business and financial results and outlook and therefore misled investors by misrepresenting and failing to disclose material problems with  sales to the
United States federal government . . .[and] problems with [its] sales management team. Because this lawsuit is in its initial stage, it is not possible to reliably predict the outcome of the litigation. Therefore, we cannot estimate
the loss, if any, associated with the litigation. We intend to contest the claims associated with this lawsuit vigorously. We believe that the claims asserted have no merit.

As each of these matters is in an early stage, we are currently unable to determine if the resolution of these matters will have an
adverse effect on our financial position, liquidity or results of operations. We currently have no other material legal proceedings pending other than the matters described above.



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

Except as
set forth below, there have been no material changes from the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

Litigation exposure related to our pending and any future litigation could exceed our expectations and adversely affect our results of operations, profitability and cash flows.

We have been and may be involved, from time-to-time, in disputes incidental to our business. We are currently the subject of
allegations of patent infringement and certain violations of the securities laws further described under the caption Legal Proceedings in Part II, Item 1 of this quarterly report on Form 10-Q. We cannot predict when these
lawsuits will be completed and are unable to accurately assess the financial outcome that could result from these matters at this time. These lawsuits may result in a diversion of managements attention and resources, including the significant
costs of document production and legal fees, and may contribute to current and future stock price volatility. No assurance can be made that these matters will not have material financial exposure, which together with the potential for similar suits
and reputational harm, could have a material adverse effect upon our results of operations, profitability and cash flows.

|Item 2. | Unregistered Sales of Equity Securities and Use of Proceeds
|------- | -----------------------------------------------------------

On August 2, 2010, our board of directors approved a share repurchase program, authorizing us to purchase up to $25.0 million of our outstanding common stock. We were authorized to make
purchases in the open market and purchases were funded from available working capital. The share repurchase program was completed in August 2010, and we repurchased 1.7 million shares of our common stock for an aggregate purchase price of
$25.0 million. Shares were retired upon repurchase. Our policy related to repurchases of our common stock is to charge any excess of cost over par value entirely to additional paid-in capital in absence of retained earnings.

The following table sets forth the repurchase of our common stock during the third quarter of 2010:
