RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information in this prospectus before making a decision to invest in our common stock. If any of such risks actually occur, our business, operating results, financial condition or growth prospects could be adversely affected. In those cases, the trading price of our common stock could decline and you may lose all or part of your investment.

Risks Related to Our Business

The extreme turmoil in the mortgage industry that began in 2007 has adversely affected and may continue to affect our business adversely.

As a result of the extreme turmoil in the mortgage industry and general economy that began in 2007, many mortgage originators and other mortgage industry participants have gone out of business. In addition, those industry participants that continue in business face increased operating and regulatory challenges. Conditions that negatively impact our Encompass users or Ellie Mae Network participants have had a significant adverse effect on our business. For example, the number of Encompass users declined 29% from approximately 79,000 at December 31, 2006 to approximately 56,000 at December 31, 2009. In addition, 30 of the 44 lenders accepting loans through the Ellie Mae Network went out of business or stopped funding loans for other mortgage originators between March 2007 and August 2009. In addition, the population of mortgage origination professionals who are the potential users of our Encompass software dropped 49% from approximately 495,000 at December 31, 2006 to approximately 253,000 at December 31, 2009. If conditions in the mortgage industry were to deteriorate further, our business would be materially adversely affected.

The anticipated increase in mortgage interest rates, as well as other factors, is expected to decrease mortgage lending volume in 2010 and 2011, which could adversely affect our business.

Mortgage interest rates are currently near historic lows and many economists predict that mortgage interest rates will rise in 2010. Mortgage interest rates are influenced by a number of factors, particularly monetary policy. The Federal Reserve Bank may raise the Federal funds rate and has ceased purchasing Fannie Mae and Freddie Mac mortgage-backed securities, each of which would likely cause mortgage interest rates to rise. Increases in mortgage interest rates would reduce the volume of new mortgages originated, in particular the volume of mortgage refinancings. For example, the increase in mortgage interest rates in the second half of 2009 contributed to a significant decline in our revenues from transactions through the Ellie Mae Network and the services we provide.

Additional factors that adversely impact mortgage lending volumes include reduced consumer and investor demand for mortgages, increased illiquidity in the secondary mortgage market, high levels of unemployment, high levels of consumer debt, lower consumer confidence, changes in tax and other regulatory policies and other macroeconomic factors.

The expected decrease in residential mortgage loan volume from 2009 volume for at least the next two years will require us to increase our revenues per loan effected through the Ellie Mae Network in order to maintain our financial performance. Any additional unforeseen decrease in residential mortgage volumes would exacerbate our need to increase revenues per loan effected through the Ellie Mae Network. We cannot assure you that we will be successful in our efforts to increase our revenues per loan effected through the Ellie Mae Network, which could materially adversely affect our business.

Our future performance will be highly dependent on our ability to continue to attract Encompass SaaS customers, and to grow revenues from our recently-introduced Ellie Mae Network Plus offerings and our services.

Mortgage loan volume is expected to decrease from 2009 volume levels for each of 2010 and 2011. To increase our revenues, we must increase the percentage of our software users who choose Encompass SaaS, from which we generate higher revenues than from our license offering. We must also increase use of our Ellie Mae Network Plus offerings and our services, such as compliance and document preparation. We only began to offer Ellie Mae Network Plus in the fourth quarter of 2009 and our Encompass Compliance Service in the first quarter of 2010. Revenue from them has not been significant and we cannot assure you that these offerings will be successful. In the event these efforts are not successful, our business and growth prospects would be adversely affected.

If we fail to increase the number of Encompass users and other Ellie Mae Network participants or retain existing users and participants, our business may be harmed.

Our growth depends in large part on increasing the number of Encompass users and other Ellie Mae Network participants. To attract lenders and service providers to the Ellie Mae Network, we must convince them that the utility of, and access to mortgage originators on, the Ellie Mae Network is worth making payments to us for transactions ordered through the network by Encompass users. To grow our base of Encompass software users, we must enhance the features and functionality of our Encompass software, convince mortgage originators of the benefits of our software solution and the Ellie Mae Network and encourage them to switch from competing loan origination software products or to forego using traditional mortgage origination methods, including paper, facsimile, courier and mail. Due to the fragmented nature of the mortgage industry, many mortgage industry participants may not be familiar with our Encompass solutions and the benefits of the Ellie Mae Network. We cannot assure you that we will be successful in attracting new Encompass users and other Ellie Mae Network participants and if we are unsuccessful in these efforts, our business may be harmed.

Additionally, existing Encompass users and other Ellie Mae Network participants may decide not to continue to use our solutions in favor of other means for financial or other reasons. We have agreements in place with various third-party lenders, service providers and investors to facilitate integration between their businesses and the Ellie Mae Network. Most of these contracts are not long term or are subject to termination rights. An unexpected termination, or a failure to renew, of a significant number of our agreements or relationships with third-party lenders, service providers or investors could have an adverse effect on our business.

We recently introduced many of our current products and services and as a result, we cannot assure that we will achieve widespread market acceptance of these products and services.

We introduced our Encompass software solution in 2003 and released the Encompass 360 version in 2009. We enhanced our Encompass Closer document preparation services in 2008, introduced our Ellie Mae Network Plus offerings in the fourth quarter of 2009, and commenced our Encompass Compliance Service in early 2010. We cannot assure that these products and services will achieve market acceptance.

The success of our business depends both on the continuation of the trend toward electronic processing of mortgages and our ability to increase the use of the Ellie Mae Network to order settlement services.

In order to grow our business, we must expand the use of settlement services on, and increase the number of transactions ordered through, the Ellie Mae Network. Our Encompass users currently employ the Ellie Mae Network to handle on average only three out of ten transactions per loan file,

12

Table of Contents

typically including ordering credit reports and accessing the automatic underwriting systems of Fannie Mae and Freddie Mac. This limited use is in part due to the fact that many providers of other settlement services, such as title reports and appraisals, do not provide electronic solutions that are superior to traditional processes. Increasing the number of transactions ordered through the Ellie Mae Network depends in large part on our ability to educate providers of settlement services of the benefits of electronic origination and network participation and our ability to encourage providers of settlement services to deliver their services electronically through the Ellie Mae Network in a manner that is attractive to mortgage professionals. If our future sales and marketing efforts are not successful in educating and encouraging additional mortgage originators and providers of settlement services to change their current business practices and adopt electronic mortgage origination and electronic delivery practices, our business may be adversely affected.

A continuation of the shift in residential mortgage volume to the retail channels of mega lenders would adversely affect our business opportunities.

Due in part to the turmoil in the mortgage industry, the percentage of the national volume of residential mortgages in the United States that were funded directly through the retail channels of mega lenders increased from 38% in 2006 to 48% in 2009. ⁶ We market our Encompass software to mortgage lenders and mortgage brokerages rather than to the retail channels of the mega lenders that generally have their own proprietary loan origination software and do not participate on the Ellie Mae Network. If this shift continues, our business and growth prospects would be materially adversely affected.

We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.

Our revenues and operating results have in the past and could in the future vary significantly from quarter to quarter and year to year because of a variety of factors, many of which are outside of our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful. In addition to other risk factors discussed in this section, factors that may contribute to the variability of our quarterly and annual results include:

As a result of these and other factors, our results have in the past and may in the future not achieve our internal projections. In addition, our operating results in future periods may not meet the expectations of investors or public market analysts who follow our company, which could cause our stock price to decline rapidly and significantly. The results of any prior quarterly or annual periods should not be relied upon as indications of our future operating performance.

Table of Contents

If we fail to implement proper and effective internal controls, disclosure controls and corporate governance procedures, our ability to produce accurate and timely financial reports and public disclosures could be impaired and our stock price could decline.

Prior to this offering, we have been a private company and have not filed reports with the SEC. We will become subject to the public reporting requirements of the Securities Exchange Act of 1934 upon the completion of this offering. As a public reporting company listed on the NYSE, we will be required, among other things, to maintain a system of effective internal control over financial reporting. We produce our consolidated financial statements in accordance with the requirements of generally accepted accounting principles in the United States, or U.S. GAAP, but our internal controls do not currently meet all of the standards applicable to companies with publicly-traded securities. We also will be required to implement effective disclosure controls and procedures and maintain corporate governance standards that were not applicable to us as a private company.

Effective internal controls are necessary for us to produce reliable financial reports and are important in our effort to prevent financial fraud. As a public company, we will be required to evaluate periodically the effectiveness of the design and operation of our internal controls over financial reporting. These evaluations may result in the conclusion that enhancements, modifications or changes to our internal controls are necessary or desirable. Although we have begun recruiting additional finance and accounting personnel with public company experience, we will need to hire additional personnel to meet these requirements. Our ability to hire and retain qualified personnel may affect our ability to meet these requirements. We have not yet begun the process of documenting, evaluating and adjusting certain of our internal control processes and systems. Improvements in our internal control processes and systems can only be accomplished over time, and our initiatives ultimately may not result in an effective internal control environment.

Our independent registered public accountants have determined that we have significant deficiencies in internal controls with respect to our issuances of equity securities and granting of stock options as a private company and corporate governance and qualifications of key personnel. Due in part to these significant deficiencies, certain issuances of capital stock and option grants were not documented or properly authorized in compliance with all corporate law requirements. We have taken certain actions to remediate the significant deficiencies with respect to the issuance of equity securities and the granting of stock options, including re-allocating responsibilities for issuances of equity securities and stock options, and are commencing actions to remediate the significant deficiency with respect to corporate governance. We cannot however assure that such actions will be successful in remediating the significant deficiencies. In addition, we have taken actions to address the issuances which were not properly authorized. We cannot assure you that we will not receive claims in the future from other persons asserting rights to shares of our capital stock or to stock option grants. Any such claims could result in substantial costs, dilution and diversion of resources.

If we fail to implement and maintain an effective system of internal control over financial reporting and disclosure controls and procedures, we may be unable to produce timely, reliable financial reports and public disclosures or prevent fraud. Similarly, if management or our independent registered public accounting firm were to discover material weaknesses in our internal controls or if we fail to transition to and maintain corporate governance standards applicable to companies with publicly traded securities, it could result in loss of investor confidence and a decline in our stock price.

The mortgage industry is heavily regulated and changes in current legislation or new legislation could adversely affect our business.

Changes in the regulations that govern our customers could adversely affect our business.

The U.S. mortgage industry is heavily regulated. Federal and state governments and agencies could enact legislation or other policies that could negatively impact the business of our Encompass

14

Table of Contents

users and other Ellie Mae Network participants. Any changes to existing laws or regulations or adoption of new laws or regulations that increase restrictions on the residential mortgage industry may decrease residential mortgage volume or otherwise limit the ability of our Encompass users and Ellie Mae Network participants to operate their businesses, resulting in decreased usage of our solutions.

Changes in current legislation or new legislation may increase our costs by requiring us to update our products and services.

Changes to existing laws or regulations or adoption of new laws or regulations relating to the residential mortgage industry could require us to incur significant costs to update our products and services. For example, our Encompass Compliance Service analyzes mortgage loan data for compliance with consumer protection laws and institutionally mandated compliance policies and must continually be updated to incorporate changes to such laws and policies. Additionally, we substantially updated our Encompass software in 2009 to reflect the changes to the Real Estate Settlement Procedures Act of 1974, as amended, or RESPA, that went into effect on January 1, 2010. These updates have caused us to incur significant expense, and future updates will likely similarly cause us to incur significant expense.

A failure of our products and services or a failure to appropriately update our products and services to reflect and comply with changes to existing laws or regulations or with new laws or regulations may contribute to violations by our customers of such laws and regulations. We provide a limited warranty for our Encompass Compliance Service, pursuant to which we agree to reimburse customers for losses incurred due to fines, penalties or judgments as a result of a violation of a specific law, rule or regulation tied to an error in the provision of our Encompass Compliance Service. Our maximum exposure is limited under our services agreements; however, under certain circumstances our exposure could be as high as $5.0 million. Although we have not historically incurred any claims and maintain a total of $5.0 million in professional liability insurance coverage, to the extent we were to become liable for an amount in excess of such coverage, our business and our reputation would be materially adversely affected.

We may be limited in the way in which we market our business or generate revenue by U.S. federal law prohibiting referral fees in real estate transactions; if we are found to be in violation of such laws we would be subject to significant liability.

RESPA generally prohibits the payment or receipt of fees or any other thing of value for the referral of business related to a residential real estate settlement service and prohibits fee shares or splits or unearned fees in connection with the provision of such services. Our Encompass software and services and the Ellie Mae Network were designed with payment methods that are not currently prohibited by the restrictions under RESPA. Nonetheless, RESPA may restrict our ability to enter into marketing and distribution arrangements with third-parties, for existing or newly developed products and services, particularly to the extent that such arrangements may be characterized as involving payments for the referral of residential real estate settlement service business. Additionally, any amendments to RESPA that result in restrictions on our current payment methods, or any determination that our payment methods have been and currently are subject to the restrictions under RESPA, could have a material adverse effect on our business. Finally, if we were found to be in violation of RESPA rules, we would be exposed to significant potential liability that could have a material adverse effect on our reputation and business.

Our failure to protect the confidential information of our Encompass users, our Ellie Mae Network participants and their respective customers could damage our reputation and brand and substantially harm our business.

Certain confidential information relating to certain of our Encompass users, our Ellie Mae Network participants and their respective customers resides on our third-party hosted data center servers and is

15

Table of Contents

transmitted over our network. We rely on encryption and authentication technology licensed from third parties to effect secure transmission of confidential information, including personal information and credit card numbers. Advances in computer capabilities, new discoveries in the field of cryptography or other developments may result in a compromise or breach of the technology used by us to protect customer transaction data. These servers may also be vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems, which could lead to loss of critical data or the unauthorized disclosure of confidential customer data.

The possession and use of personal information in conducting our business subject us to legislative and regulatory burdens that may require notification to customers of a security breach, restrict our use of personal information and hinder our ability to acquire new customers or market to existing customers.

We cannot guarantee that our security measures will prevent security breaches. Any such compromise of our security could damage our reputation and brand and expose us to a risk of loss or litigation and potential liability, which would substantially harm our business and operating results. We may need to expend significant resources to protect against and remedy any potential security breaches and their consequences.

We depend on key and highly skilled personnel to operate our business, and if we are unable to retain our current or hire additional personnel, our ability to develop and successfully market our business could be harmed.

We believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial, technical, finance, creative and sales and marketing personnel. Moreover, we believe that our future success is highly dependent on the contributions of our named executive officers, as defined in “Management-Executive Compensation” below. All of our officers and other employees are at-will employees, which means they may terminate their employment relationship with us at any time, and their knowledge of our business and industry would be extremely difficult to replace. In addition, the loss of any key employees or the inability to attract or retain qualified personnel could delay the development and introduction of, and harm our ability to sell, our solutions and harm the market’s perception of us. Competition for qualified personnel is particularly intense in the San Francisco Bay Area, where our headquarters are located. Qualified individuals are in high demand, and we may incur significant costs to attract them. We may be unable to attract and retain suitably qualified individuals who are capable of meeting our growing sales, operational and managerial requirements, or may be required to pay increased compensation in order to do so. If we are unable to attract and retain the qualified personnel we need to succeed, our business will suffer.

Volatility or lack of performance in our stock price may also affect our ability to attract and retain our key employees. Our named executive officers have become, or will soon become, vested in a substantial amount of stock options. Employees may be more likely to leave us if the shares they own or the shares underlying their vested options have significantly appreciated in value relative to the original purchase prices of the shares or the exercise prices of the vested options, or if the exercise prices of the options that they hold are significantly above the market price of our common stock. If we are unable to retain our named executive officers or other key employees, our business will be harmed.

Growth may place significant demands on our management and our infrastructure.

Our growth has placed and may continue to place significant demands on our management and our operational and financial infrastructure. As our operations grow in size, scope and complexity, we will need to improve and upgrade our systems and infrastructure to offer an increasing number of customers enhanced solutions, features and functionality. The expansion of our systems and

16

Table of Contents

infrastructure will require us to commit substantial financial, operational and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Continued growth could also strain our ability to maintain reliable service levels for our customers, develop and improve our operational, financial and management controls, enhance our reporting systems and procedures and recruit, train and retain highly skilled personnel.

Managing our growth will require significant expenditures and allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as it grows, our business would be harmed.

We operate in a highly competitive market, which could make it difficult for us to attract and retain Encompass users and Ellie Mae Network participants.

The mortgage origination software market is highly competitive. There are many software providers, such as Calyx Technology, Inc., Byte Software Inc., Del Mar DataTrac, Inc. and Harland Financial Solutions, that compete with us by offering loan origination software to mortgage originators. Some software providers, including Calyx Technology, Inc., also provide connectivity between their software users and lenders and service providers. Other connectivity alternatives are provided by vendors such as MGIC Investment Corporation and RealEC Technologies. We also compete with compliance and document preparation service providers that are much larger and more established than us. There is vigorous competition among providers of these services and we may not succeed in convincing potential customers, which use other services, to switch to our services. Many service providers connect directly to mortgage originators without using any loan origination software. If we are unsuccessful in competing effectively by providing attractive functionality, customer service or value, we could lose existing Encompass users to our competitors and our ability to attract new Encompass users could be harmed.

We only offer our Encompass services to Encompass users. There are many other service providers that offer our Encompass users competing services, including borrower-facing websites, document preparation services, compliance services and electronic document management. We may be unsuccessful in continuing to differentiate our Encompass service offerings to the extent necessary to effectively compete in some or all of these markets.

The Ellie Mae Network is only available to mortgage originators using Encompass software. The principal alternative to the use of the Ellie Mae Network by Encompass users remains traditional methods of exchanging data and documents among mortgage industry participants by e-mail, facsimile, phone, courier and mail. In addition, mortgage originators use standalone web browsers to go individually to each investor, lender or service provider’s website and then manually uploading loan data or entering information into the website. Mortgage originators may continue to use these methods due to habit, personal business relationships or otherwise. The success of the Ellie Mae Network depends on our ability to achieve and offer access to both the critical mass of investors, lenders and service providers necessary to attract and retain mortgage originators on the Ellie Mae Network and the critical mass of active mortgage originators necessary to attract and retain investors, lenders and service providers on our network.

Many of our actual and potential competitors have longer operating histories and significantly greater financial, technical, marketing and other resources than we do and, as a result, these companies may be able to respond more quickly to changes in regulations, new technologies or customer demands, or devote greater resources to the development, promotion and sale of their software and services than we can. We expect the mortgage origination market to continue to attract new competitors and there can be no assurance that we will be able to compete successfully against current or future competitors, or that competitive pressures we face will not materially adversely affect our business.

System interruptions that impair access to the Ellie Mae Network or our hosted Encompass software could damage our reputation and brand and substantially harm our business.

The satisfactory performance, reliability and availability of the Ellie Mae Network, our hosted Encompass software, website and network infrastructure are critical to our reputation and our ability to attract and retain Ellie Mae Network participants and Encompass software users. Any systems interruption that results in the unavailability of our network or impairs access to Ellie Mae Network participants connected to our network could result in negative publicity, damage our reputation and brand and cause our business and operating results to suffer.

We may experience temporary system interruptions, either to the Ellie Mae Network or to our Encompass software hosting locations, for a variety of reasons, including network failures, power failures, software errors or an overwhelming number of Ellie Mae Network participants and Encompass software users trying to access our network during periods of strong demand. In addition, our two primary data centers, located in Santa Clara, California and Chicago, Illinois, are hosted by a third-party service provider over which we have little control. We depend on this third-party service provider to provide continuous and uninterrupted access to the Ellie Mae Network and our hosted Encompass software. If for any reason our relationship with this third-party were to end, it would require a significant amount of time to transition the hosting of our data centers to a new third-party service provider.

Because we are dependent on third-parties for the implementation and maintenance of certain aspects of our systems and because some of the causes of system interruptions may be outside of our control, we may not be able to remedy such interruptions in a timely manner, if at all. As we rely heavily on our servers, computer and communications systems and the Internet to conduct our business, any system disruptions could negatively impact our ability to run our business and either directly or indirectly disrupt our customers’ businesses, which could have an adverse effect on our business.

Failure to adapt to technological changes may render our technology obsolete or decrease the attractiveness of our solutions to our customers.

If new industry standards and practices emerge, or if competitors introduce new solutions embodying new services or technologies, our Encompass software and the Ellie Mae Network technology may become obsolete. Our future success will depend on our ability to:

We must continue to enhance the features and functionality of our Encompass software and the Ellie Mae Network. The effective performance, reliability and availability of our Encompass software and the Ellie Mae Network infrastructure are critical to our reputation and our ability to attract and retain Encompass users and Ellie Mae Network participants. If we do not continue to make investments in product development and, as a result, or due to other reasons, fail to attract new and retain existing mortgage originators, lenders, investors and service providers, we may lose existing Ellie Mae Network participants, which could significantly decrease the value of the Ellie Mae Network to all participants.

Failure to adequately protect our intellectual property could harm our business.

The protection of our intellectual property rights, including our proprietary Encompass software and Ellie Mae Network technology, is crucial to the success of our business. We rely on a combination

18

Table of Contents

of patent, copyright, trademark and trade secret law and contractual restrictions to protect our intellectual property. Our present and future patents may provide only limited protection for our technology and may not be sufficient to provide competitive advantage to us. Furthermore, we cannot assure you that any patents will be issued to us as a result of our patent applications. We also rely in part on confidentiality and invention assignment agreements with our employees, independent contractors and consultants. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our Ellie Mae Network and Encompass software features and functionality or obtain and use information that we consider proprietary. Policing our proprietary rights is difficult and may not always be effective.

We have registered “Ellie Mae” and “Encompass” and certain of our other trademarks as trademarks in the United States. Competitors may adopt service names similar to ours, thereby impeding our ability to build brand identity and possibly leading to customer confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of the terms Ellie Mae, Encompass or our other trademarks.

Litigation or proceedings before the U.S. Patent and Trademark Office or other governmental authorities and administrative bodies in the United States and abroad may be necessary in the future to enforce our intellectual property rights, protect our patent and copyright rights, trade secrets and domain names and determine the validity and scope of the proprietary rights of others. Our efforts to enforce or protect our proprietary rights may be ineffective and could result in substantial costs and diversion of resources and could harm our business.

Assertions that we infringe third-party intellectual property rights could result in significant costs and substantially harm our business.

Other parties have asserted, and may in the future assert, that we have infringed their intellectual property rights. In addition, we generally agree to indemnify our customers against legal claims that our software products infringe intellectual property rights of third parties and, in the event of an infringement, to modify or replace the infringing product or, if those options are not reasonably possible, to refund the cost of the software, as pro-rated over a period of years. We cannot predict whether assertions of third-party intellectual property rights or claims arising from such assertions will substantially harm our business and operating results. If we are forced to defend against any infringement claims, whether they are with or without merit or are determined in our favor, we may face costly litigation and diversion of technical and management personnel. Furthermore, an adverse outcome of a dispute may require us to: pay damages, potentially including treble damages and attorneys’ fees if the infringement were found to be willful; cease providing solutions that allegedly incorporate the intellectual property of others; expend additional development resources to redesign our solutions; and enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies. Any required royalty or licensing agreements may be unavailable on terms acceptable to us, if at all.

Current or future litigation could substantially harm our business.

We have been and continue to be involved in legal proceedings, claims and other litigation. For example, we are currently a defendant in litigation initiated by DocMagic Inc., which alleges, among other claims, that we had engaged in monopolization and/or attempted monopolization, intentional interference with contractual relationship, interference with prospective economic advantage, unfair competition and breach of contract. In addition, we are currently involved in defending against other lawsuits alleging, among other claims, breach of contract, tortious interference with business relationship, unfair trade practices, defamation and negligence. See “Business—Legal Proceedings”

19

Table of Contents

below. Furthermore, we are also subject to various other legal proceedings and claims arising out of the ordinary course of business. While we do not expect the outcome of any such pending litigation to have a material adverse effect on our financial position, litigation is unpredictable and excessive verdicts, both in the form of monetary damages and injunctions, could occur. In the future, litigation could result in substantial costs and diversion of resources and we could incur judgments or enter into settlements of claims that could have a material adverse effect on our business.

If one or more U.S. states or local jurisdictions successfully assert that we should have collected or in the future should collect additional sales or use taxes on our fees, we could be subject to additional liability with respect to past or future sales, and the results of our operations could be adversely affected.

We do not collect state and local sales and use taxes in all jurisdictions in which our customers are located, based on our belief that such taxes are not applicable. Sales and use tax laws and rates vary by jurisdiction and such laws are subject to interpretation. Jurisdictions in which we do not collect sales and use taxes may assert that such taxes are applicable, which could result in the assessment of such taxes, interest and penalties, and we could be required to collect such taxes in the future. This additional sales and use tax liability could adversely affect the results of our operations.

Our business is subject to the risks of earthquakes, fires, floods and other natural catastrophic events and to interruption by man-made problems such as terrorism.

Our systems and operations are vulnerable to damage or interruption from earthquakes, fires, floods, power losses, telecommunications failures, terrorist attacks, acts of war and similar events. For example, a significant natural disaster, such as an earthquake, fire or flood, could have a material adverse impact on our business, operating results and financial condition, and our insurance coverage may be insufficient to compensate us for losses that may occur. Our corporate offices and one of the facilities we lease to house our computer and telecommunications equipment are located in the San Francisco Bay Area, a region known for seismic activity. In addition, acts of terrorism, which may be targeted at metropolitan areas which have higher population density than rural areas, could cause disruptions in our or our customers’ businesses or the economy as a whole. We may not have sufficient protection or recovery plans in certain circumstances, such as natural disasters affecting the San Francisco Bay Area, and our business interruption insurance may be insufficient to compensate us for losses that may occur.

Future acquisitions could disrupt our business, harm our financial condition and operating results or dilute, or adversely affect the price of, our common stock.

Our success will depend, in part, on our ability to expand our solutions and services and grow our business in response to changing technologies, customer demands and competitive pressures. In some circumstances, we may pursue growth through the acquisition of complementary businesses, solutions or technologies rather than through internal development. For example, in December 2009 we acquired Mavent Holdings Inc. to add automated regulatory compliance to our services offerings. The identification of suitable acquisition candidates can be difficult, time-consuming and costly, and we may not be able to complete identified acquisitions successfully. Even if we successfully complete an acquisition, we may not be able to assimilate and integrate effectively the acquired business, technologies, solutions, assets, personnel or operations, particularly if key personnel of an acquired company decide not to work for us. In addition, we may issue equity securities to complete an acquisition, which would dilute our stockholders’ ownership and could adversely affect the price of our common stock.

20

Table of Contents

We will incur increased costs as a result of being a public company, which may strain our resources and adversely affect our operating results and financial condition.

As a public company, we will incur significant accounting, legal and other expenses that we did not incur as a private company. We will incur costs associated with our public company reporting requirements, since we will be subject to the requirements of the Securities Exchange Act of 1934, the Sarbanes-Oxley Act of 2002, the New York Stock Exchange, or NYSE, and other rules and regulations. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. Furthermore, these laws and regulations could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

Risks Related to Owning Our Common Stock

An active, liquid and orderly market for our common stock may never develop or be sustained.

Prior to this offering there has been no market for shares of our common stock. An active trading market for our common stock may never develop or be sustained, which could depress the market price of our common stock and could affect your ability to sell your shares. The initial public offering price will be determined through negotiations between us and the representative of the underwriters and may bear no relationship to the price at which our common stock will trade following the completion of this offering. The trading price of our common stock following this offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this prospectus, these factors include:

In addition, the stock market in general has experienced extreme price and volume fluctuations. These fluctuations may be even more pronounced in the trading market for our stock shortly following this offering. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. This litigation, if instituted against us, could result in very substantial costs, divert our management’s attention and resources and harm our business.

21

Table of Contents

Our directors, executive officers and principal stockholders will continue to have substantial control over us after this offering and could delay or prevent a change in corporate control.

After this offering, our directors, executive officers and holders of more than 5% of our common stock, together with their affiliates, will beneficially own, in the aggregate, approximately     % of our outstanding common stock, assuming no exercise of the underwriters’ option to purchase additional shares of our common stock in this offering. As a result, these stockholders, acting together, would have the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, would have the ability to control the management and affairs of our company. Accordingly, this concentration of ownership might harm the market price of our common stock by:

Future sales of shares of our common stock by existing stockholders could depress the price of our common stock.

If our existing stockholders sell, or indicate an intent to sell, substantial amounts of our common stock in the public market after the 180-day contractual lock-up and other legal restrictions on resale discussed in this prospectus lapse, the trading price of our common stock could decline significantly and could decline below the initial public offering price. Based on shares outstanding as of December 31, 2009, upon completion of this offering, we will have outstanding approximately              shares of common stock.              shares of common stock, plus any shares sold upon exercise of the underwriters’ overallotment option, will be immediately freely tradable, without restriction, in the public market.

After the lock-up agreements pertaining to this offering expire and based on shares outstanding as of December 31, 2009, an additional              shares will be eligible for sale in the public market. Representatives of the underwriters may, in their sole discretion, permit our officers, directors, employees and current stockholders to sell shares prior to the expiration of the lock-up agreements. In addition, 9,126,617 shares subject to outstanding options, as of December 31, 2009, and 2,037,856 shares reserved for future issuance under our equity incentive plans, as of December 31, 2009, will become eligible for sale in the public market, subject to certain legal and contractual limitations. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the price of our common stock could decline substantially.

If we issue additional shares of common stock to raise capital, it may have a dilutive effect on your investment.

If we raise additional capital through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution in their percentage ownership of us. Moreover, any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock, including shares of common stock sold in this offering.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts do not

currently, and may never, publish research on our company. If no securities or industry analysts commence coverage of our company, the trading price for our stock would likely be negatively impacted. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

Our management will have broad discretion over the use of the proceeds we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.

Our management will have broad discretion to use the net proceeds to us from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. Our management might not apply the net proceeds from this offering in ways that increase the value of your investment. We expect to use the net proceeds to us from this offering for working capital and other general corporate purposes, including the funding of our marketing activities and the costs of operating as a public company, as well as further investment in the development of our proprietary technologies. We may also use a portion of the net proceeds for the acquisition of businesses, solutions and technologies that we believe are complementary to our own, although we have no agreements or understandings with respect to any acquisition at this time. We have not allocated the net proceeds from this offering for any specific purposes. Until we use the net proceeds to us from this offering, we plan to invest them, and these investments may not yield a favorable rate of return. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

Certain provisions in our charter documents and Delaware law could discourage takeover attempts and lead to management entrenchment.

Our certificate of incorporation and bylaws that will be in effect prior to the closing of this offering will contain provisions that could have the effect of delaying or preventing changes in control or changes in our board of directors. These provisions will include:

We are also subject to certain anti-takeover provisions under Delaware law. Under Delaware law, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other things, the board of directors has approved the transaction.
