Set forth below and elsewhere in this quarterly report and in the other documents we file with the SEC are risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this quarterly report. Prospective and existing investors are strongly urged to carefully consider the various cautionary statements and risks set forth in this quarterly report and our other public filings.

We have experienced in the past, and may experience in the future, a shortfall in revenue or earnings or otherwise fail to meet public market expectations, which could materially and adversely affect our business and the market price of our common stock. Our total revenue, expenses and operating results may fluctuate significantly because of a number of factors, many of which are outside of our control. These factors include:

• Corporate and consumer confidence in the economy, evidenced, in part, by stock market levels;


• Changes in the domestic and international economic, business and political conditions;


• Economic conditions within the information technology industry;


• Economic conditions within the key industries in which we derive our revenues, including the manufacturing and distribution, communications, financial services, life sciences and public sector industries;


• Legal and other costs relating to defending intellectual property, regulatory enforcement actions and other types of litigation;


• Level of product and price competition;


• Length of our sales cycle and the discretionary nature of our customers' purchase and budget cycles;


• Size and timing of individual license transactions;


• Levels of international license transactions;


• Delay or deferral of customer implementations of our products;


• Success in expanding our professional services organization, direct sales force and indirect distribution channels;


• Our ability to develop or acquire and market new products and services and control costs;


• Timing of new product introductions and product enhancements;


• Appropriate mix of products licensed and services sold;


• Activities of and acquisitions by competitors;


• Success of, and costs associated with, integrating and achieving the anticipated benefits of our acquisitions;


• Timing of new hires and the allocation of our resources;


• Increases in the cost of software and professional services;


• Variations in marketing expenditures and our success in generating additional sales pipeline from those expenditures;


• The size of and conversion rates of our sales pipeline;


• Changes in foreign currency exchange rates;


• Changes in domestic and foreign tax laws;


• Seasonal variations in operating results;


• Variations in the fiscal or quarterly cycles of our customers; and


• Changes in accounting principles generally accepted in the United States.

One or more of the foregoing factors, as well as other factors, may cause our operating expenses to be disproportionately high during any given period or may cause our net revenue and operating results to fluctuate significantly, which could materially and adversely affect our business, financial condition, results of operations and the market price of our common stock.

Further, each customer's decision to implement our products and services is discretionary, involves a significant commitment of resources and is subject to the customer's budget cycles. In addition, the timing of license revenue is difficult to predict because of the length of our sales cycle. We base our operating expenses on anticipated revenue trends. Because a high percentage of these expenses are relatively fixed, a delay in recognizing revenue from license transactions could cause significant variations in operating results from quarter to quarter and could result in operating losses. If these expenses precede, or are not subsequently followed by, increased revenues, our business, financial condition or results of operations could be materially and adversely affected.

We use a "pipeline" system, a common industry practice, to forecast sales and trends in our business. Our sales personnel monitor the status of all potential transactions, including the estimated closing date and potential dollar amount of each transaction. We aggregate these estimates periodically to generate a sales pipeline and then evaluate the pipeline to identify trends in our business. This pipeline analysis and related estimates of revenue may differ significantly from actual revenues in a particular reporting period. A slowdown in the global economy, among other factors, has caused and may continue to cause customer purchasing decisions to be delayed, reduced in amount or cancelled, all of which have reduced and could continue to reduce the rate of conversion of the pipeline into contracts. In addition, because a substantial portion of our software license contracts close in the latter part of a quarter, management may not be able to adjust our cost structure to respond to a variation in the conversion of the pipeline into contracts in a timely manner. Our inability to respond to a variation in the pipeline or in the conversion of the pipeline into contracts in a timely manner, or at all, could cause us to plan or budget inaccurately and thereby could adversely affect our business, financial condition or results of operations.

We realize lower margins on our professional services and maintenance revenues than on our software license revenues. In addition, we may contract with certain third parties to supplement the services we provide to customers, which generally yields lower margins than our internal services business. As a result, if services revenues increase as a percentage of total revenues or if we increase our use of third parties to provide services, our margins would be negatively impacted.

Our operations could be negatively impacted if there are additional terrorist attacks or threats of terrorist attacks, or if hostilities involving the United States escalate. In the past, terrorist attacks, including attacks on the United States and internationally, have had a significant impact on global economic conditions and our operations. Further, as a result of past terrorist attacks and hostilities involving the United States, we believe many of our customers and potential customers have been much more cautious in setting and spending against their capital expenditure budgets. Subsequent terrorist acts and/or the threat of future terrorist attacks or escalation of hostilities involving the United States or other countries could adversely affect the growth rate of our revenue and have an adverse effect on our business, financial condition or results of operations. In addition, any escalation in these events or similar future events may disrupt our operations or those of our customers, distributors and suppliers, which could adversely affect our business, financial condition or results of operations.

The timing of the sales and implementation of our products and services is lengthy and not predictable with any degree of accuracy. Prior sales and implementation cycles should not be relied upon as any indication of future cycles. The license of our software products is often an enterprise-wide decision by prospective customers and generally requires us to provide a significant level of education to prospective customers regarding the use and benefits of our products. In addition, the implementation of our software products involves a significant commitment of resources by prospective customers and may involve reengineering efforts performed by the customer or third-party systems integrators. The cost of our software product to the customer is typically only a portion of the related hardware, software, development, training and integration costs of implementing a large-scale business software system. For these and other reasons, the period between initial contact and the purchase and implementation of our software products is often lengthy and is subject to a number of factors, many of which we have little or no control over, and which can result in significant delays. These factors include the size and complexity of the overall project and delays in our customers' implementation of web-based computing environments, among others. A delay in the sale or implementation of even a limited number of license transactions could have a material adverse effect on our business, financial condition or results of operations and cause our operating results to vary significantly from quarter to quarter.

Our business is subject to changing regulation of corporate governance and public disclosure that has increased both our costs and the risk of noncompliance.

We are subject to rules and regulations of federal, state and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Public Company Accounting Oversight Board, or PCAOB, the SEC and NASDAQ, have recently issued new requirements and regulations and continue to develop additional regulations and requirements in response to recent laws enacted by Congress, most notably SOX. Our efforts to comply with these new regulations have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

In particular, our efforts to comply with Section 404 of SOX and the related regulations regarding our required assessment of our internal control over financial reporting and our external auditors' audit of that assessment has required, and continues to require, the commitment of significant financial and managerial resources. Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by on-going revisions to our disclosure and governance practices.

Our operations are subject to income, payroll and indirect taxes in the United States and in multiple foreign jurisdictions. We exercise judgment in determining our worldwide provision for these taxes, and in the ordinary course of our business there may be transactions and calculations where the ultimate tax determination is uncertain.

Our U.S. Federal income tax returns for 2001 through 2003 are currently under examination by the IRS. In addition, certain of our U.S. payroll tax returns (primarily related to taxes associated with stock option exercises), state sales and use tax returns, and international sales and value added tax returns are currently under examination and/or review by the applicable taxing authorities. While we believe that we have made adequate provisions related to the audits of these tax returns, the final determination of our obligations may exceed the amounts provided for by us in the accompanying consolidated financial statements.

Specifically, we may receive assessments related to the audits and/or reviews of our U.S. income, U.S. payroll, U.S. sales and use tax returns, or our international sales and value added tax returns that exceed amounts provided for by us. In the event we are unsuccessful in reducing the amount of such assessments, our business, financial condition or results of operations could be adversely affected. Further, if additional taxes and/or penalties are assessed as a result of these audits, there could be a material effect on our income tax provision, operating expenses and net income in the period or periods for which that determination is made.

The market for on-demand or "hosted" application services is relatively new and unproven, and it is uncertain whether these services will achieve and sustain high levels of demand and market acceptance. Our success will depend in part on the willingness of enterprises to increase their use of on-demand application services in general and for front-office applications in particular. If enterprises do not perceive the benefits of on-demand application services, then the market for these services may not develop at all, or may develop more slowly than we expect, either of which could significantly and adversely affect our operating results. In addition, if the demand for our OnDemand services does not materialize as expected, our ability to recover our investments in UpShot Corporation and Ineto Services, Inc. ("Ineto") may be impaired.

We began offering Siebel CRM OnDemand, a hosted CRM application delivered as an online service, in the fourth quarter of 2003, and Siebel Contact OnDemand, a hosted contact center application, in the first quarter of 2004. These OnDemand solutions are offered on a subscription basis, rather than as a perpetual license. Our OnDemand customers have no obligation to renew their service subscriptions after the expiration of the initial subscription period, which is typically 12 months. Some former customers of acquired businesses which are now a part of our OnDemand business have elected not to renew their subscriptions. In addition, our customers may elect to renew their service for fewer users. Because the fee structure for our OnDemand solutions is based on the number of users, this could reduce our revenue generated from this service. We have limited historical data with respect to rates of customer subscription renewals, so we cannot predict with any degree of certainty customer renewal rates. Our customers' renewal rates may decline or fluctuate as a result of a number of factors, many of which are beyond our control, including their inability to continue their operations and/or spending levels. If our customers do not renew their subscriptions for our service, or if they renew our service for fewer users, our expectations regarding future revenues from this new product offering may be incorrect, which could adversely affect our business, financial condition or results of operations.

We have entered into strategic relationships with hosting providers, including IBM and British Telecom, to provide our OnDemand service through computer hardware located at the facilities of these third parties. We do not control the operation of these facilities, which could be subject to damage or interruption from a variety of sources, including earthquakes, fires, power loss, telecommunications failures and similar events. The occurrence of one of these events or other unanticipated problems at these facilities could result in lengthy interruptions in our service. In addition, the failure by one of our hosting providers to provide the required data communications capacity could result in interruptions in our service. Interruptions in our service, among other things, may reduce our revenue, cause us to issue credits or pay penalties, cause customers to terminate their subscriptions and adversely affect our renewal rates.

Our OnDemand service involves the storage and transmission of customers' proprietary information, and security breaches could expose us to a risk of loss of this information, litigation and potential liability. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. If an actual or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed and we could lose existing customers and our ability to obtain new customers.

We have in the past and may in the future acquire additional companies, products or technologies. Most recently, we acquired edocs, Inc. in January 2005, Eontec Limited in April 2004, and Ineto in January 2004. We may not realize the anticipated benefits of these or any other acquisition and each acquisition has numerous risks. These risks include:

• difficulty in assimilating the operations and personnel of the acquired company;


• difficulty in effectively integrating the acquired technologies or products with our current products and technologies;


• difficulty in maintaining controls, procedures and policies during the transition and integration;


• disruption of our on-going business and distraction of our management and employees due to integration issues;


• inability to retain key technical and managerial personnel from the acquired business;


• inability to retain key customers, distributors, vendors and other business partners of the acquired business;


• inability to achieve the financial and strategic goals for the acquired and combined businesses;


• incurrence of acquisition-related costs or amortization costs for acquired intangible assets that could impact our operating results;


• impairment of our relationships with employees, customers, partners or third-party providers of technology or products;


• failure of the due diligence processes to identify significant issues with product quality, architecture and development, or legal and financial contingencies, among other things; and


• incurrence of significant exit charges if products acquired in business combinations are unsuccessful.

Ultimately, if we do not successfully complete the integration of acquired businesses in a timely manner, or at all, we may not realize the anticipated benefits of the acquisitions to the extent anticipated, which could adversely affect our business, financial condition or results of operations.

During 2002, 2003 and 2004, we initiated a series of restructurings of our operations involving, among other things, the reduction of our workforce and the consolidation of excess facilities (the "Restructurings"). As part of the Restructurings, we ceased to use certain of our leased facilities and, accordingly, we are negotiating certain lease terminations and/or subleases of our facilities. We cannot predict when or if we will be successful in negotiating lease termination agreements or subleases of our facilities on terms acceptable to us. If we are not successful negotiating terms acceptable to us, or at all, we may be required to materially increase our restructuring and related expenses in future periods. Further, if we consolidate additional facilities in the future, we may incur additional restructuring and related expenses, which could have a material adverse effect on our business, financial condition or results of operations.

We also cannot assure you that we will not reduce or otherwise adjust our workforce again in the future or that the related transition issues associated with such a reduction will not occur again. In addition, employees, whether or not directly affected by the reduction, may seek future employment with our business partners, customers or competitors. Although our employees are required to sign a confidentiality agreement at the time of hire, we cannot assure you that the confidential nature of certain proprietary information will be maintained in the course of such future employment. Further, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled personnel. We may have difficulty attracting such personnel as a result of a perceived risk of future workforce reductions.

If we fail to manage the size of our operations effectively, our business, financial condition or results of operations could be materially and adversely affected. Since we began operations and continuing throughout early 2001, our business grew rapidly. Beginning in early 2001 and continuing through much of 2004, our revenues declined in part as a result of a deterioration of the overall economy and information technology industry. These changes in our business have placed a significant strain on our management systems and resources. In response to the deterioration in the information technology industry, management completed a series of Restructurings, as described more fully in Note 2 to the accompanying consolidated financial statements. The Restructurings have particular risks, many of which are discussed above under "We may incur future restructuring charges, which may adversely impact our operations." In addition, if our operations return to positive growth we may need to implement new systems or upgrade current systems. The failure to successfully implement such new or improved systems could materially and adversely affect our business, financial condition or results of operations.

The majority of our expenses are personnel-related costs such as employee compensation and benefits, along with the cost of the infrastructure (occupancy and equipment) to support our employee base. The failure to adjust our employee base to the appropriate level to support our revenues could materially and adversely affect our business, operating results and financial condition. In addition, expanding the distribution of our products may place new and increased demands on our direct sales force, professional services staff, and technical and sales support staff. Although we currently believe that we invest sufficient resources in our direct sales force, professional services staff, and our technical and sales support staff, there are only a limited number of qualified personnel in these areas. Our ability to achieve expanded distribution and revenue growth in the future will depend, in part, on our success in recruiting and training sufficient direct sales, professional services, and technical and sales support personnel. If we are not be able to expand our direct sales force, professional services staff, and technical and sales support staff as necessary to support our operations, our business and operations could be harmed.

Accounting principles generally accepted in the United States are subject to interpretation by the Financial Accounting Standards Board, or FASB, the American Institute of Certified Public Accountants, the PCAOB, the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the implementation of a new accounting principle.

We currently account for stock options under APB 25 and, accordingly, we record compensation expense related to stock options if the current market price of the underlying stock exceeds the exercise price of the stock option on the date of grant. On December 15, 2004, the FASB issued SFAS 123R, which will require us to expense stock options in our statement of operations no later than January 1, 2006. SFAS 123R applies to all outstanding stock options that are not vested at the effective date and grants of new stock options made subsequent to the effective date.

Upon adoption of SFAS 123R on January 1, 2006, we estimate that our earnings in 2006 could be reduced by up to approximately $35.0 million per quarter. This estimate is based solely on the expense associated with stock options outstanding as of March 31, 2005 (including stock-based compensation under the Purchase Plan) and therefore does not take into consideration new stock option grants, which would increase this estimate, or forfeitures of stock options, which would reduce this estimate.

We have historically used stock options and other forms of equity compensation as key components of our employee compensation program in order to align employees' interests with the interests of our stockholders, encourage employee retention, and provide competitive compensation packages. The changing regulatory landscape could make it more difficult and expensive for us to grant stock options to employees in the future. In light of these changes, we have modified and anticipate that we may further modify our equity compensation strategy to emphasize equity incentives other than stock options, including increased use of certain performance-related features. If employees believe that the incentives that they would receive under a modified strategy are less attractive, we may find it difficult to attract, retain and motivate employees. In addition, the use of alternative equity incentives may increase our compensation expense and may negatively impact our earnings. To the extent that new regulations make it more difficult or expensive to grant equity instruments to employees, we may incur increased compensation costs, further change our equity compensation strategy or find it increasingly difficult to attract, retain and motivate employees, each of which could materially and adversely affect our business, financial condition or results of operations.

We have established strategic relationships with a number of organizations that we believe are important to our sales, marketing and support activities and the implementation of our products. We believe that our relationships with these organizations provide marketing and sales opportunities for our direct sales force and expand the distribution of our products. These relationships allow us to keep pace with the technological and marketing developments of major software vendors and provide us with technical assistance for our product development efforts. Failure to maintain existing strategic relationships with systems integrators, distributors, resellers and technology vendors, or to establish new relationships in the future, could have a material adverse effect on our business, financial condition or results of operations.

In particular, we have established non-exclusive strategic relationships with Accenture, Capgemini, Deloitte Consulting, IBM and BearingPoint, among others. A significant portion of our revenues has historically been derived from customers that have engaged systems integrators with which we have a relationship. Any deterioration of our relationships with these significant systems integrators could have a material adverse effect on our business, financial condition or results of operations. Our current and potential customers may also rely on third-party systems integrators to develop, deploy or manage Siebel Business Applications. If we do not adequately train a sufficient number of systems integrators, or if these integrators do not have, or do not devote, the resources necessary to implement our products, our business, financial condition or results of operations could be materially and adversely affected.

We also have relationships with technology vendors such as Hewlett-Packard, Intel, Microsoft and Sun Microsystems, among others. Failure to maintain existing relationships with such vendors on acceptable terms, or to establish new relationships with technology vendors in the future, could have a material adverse effect on our business, financial condition or results of operations.

Portions of our products incorporate software that was developed and is maintained by third-party software developers. We may not be able to replace the functionality provided by the third-party software currently offered with our products if that software becomes obsolete or incompatible with future versions of our products or is not adequately maintained or updated. Although we believe there are other sources for these products, any significant interruption in the supply of these products could adversely impact our sales unless and until we can secure another source. We depend in part on these third parties' abilities to enhance their current products, to develop new products on a timely and cost-effective basis and to respond to emerging industry standards and other technological changes. The inability to replace, or any significant delay in the replacement of, functionality provided by third-party software in our products could materially and adversely affect our business, financial condition or results of operations.

Our customers frequently deploy our products to large numbers of sales, marketing and customer service personnel. These end users may not accept our products. Our products are also being deployed on a variety of computer hardware platforms and used with a number of third-party software applications and programming tools. This use may present significant technical challenges, particularly as large numbers of personnel attempt to use our products concurrently. If existing customers have difficulty deploying Siebel Business Applications or our OnDemand solutions or for any other reason are not satisfied with Siebel Business Applications or our OnDemand solutions, our business, financial condition or results of operations could be materially and adversely affected.

We have a number of relationships with third-party resellers that assist us in selling our products. We generally do not have exclusive relationships with these resellers. In an effort to minimize channel conflicts among our resellers, we have implemented certain policies and licensing programs with each of our resellers. These policies and programs may not effectively minimize or eliminate all channel conflicts. Failure to minimize channel conflicts could result in lost sales opportunities or impair our relationship with our third-party resellers or customers, among other consequences, which could materially and adversely affect our business, operating results and financial condition.

The software market in which we compete is characterized by (i) rapid technological change, (ii) frequent introductions of new products, (iii) changing customer needs, and (iv) evolving industry standards. To keep pace with technological developments, evolving industry standards and changing customer needs, we must support existing products and develop new products. We may not be successful in developing, marketing and releasing new products or enhancements to Siebel Business Applications or our OnDemand solutions that respond to technological developments, evolving industry standards or changing customer requirements. We may also experience difficulties that could delay or prevent the successful development, introduction and sale of these new products or enhancements. In addition, these new products or enhancements may not adequately meet the requirements of the marketplace and may not achieve any significant degree of market acceptance. If release dates of any future products or enhancements to Siebel Business Applications or our OnDemand solutions are delayed, or if these products or enhancements fail to achieve market acceptance when released, our business, operating results or financial condition could be materially and adversely affected. In addition, new products or enhancements by our competitors may cause customers to defer or forego purchases of our products, which could have a material adverse effect on our business, financial condition or results of operations.

Siebel Business Applications and our OnDemand solutions communicate through public and private networks over the Internet. The success of our products and services may depend, in part, on our ability to continue developing products and services that are compatible with the Internet. The increased commercial use of the Internet could require substantial modification and customization of our products and services and the introduction of new products and services. Further, critical issues concerning the commercial use of the Internet, including security, privacy, demand, reliability, cost, ease-of-use, accessibility, quality of service, the impact of "viruses," "worms" and similar malicious programs, and potential tax or other government regulation remain unresolved and may affect the use of the Internet as a medium to support the functionality of our products and services and the distribution of our software. If these critical issues are not favorably resolved, our business, financial condition or results of operations could be materially and adversely affected.

If the web-based applications market fails to grow at the pace we expect or at all, our business, financial condition or results of operations could be materially and adversely affected. The market for web-based applications software is relatively new, highly competitive and rapidly changing. We market our products primarily to customers who have migrated or are in the process of migrating their enterprise computing systems to web-based computing environments. Our future financial performance will partly depend on the continued growth of organizations successfully adopting web-based computing environments.

Our products are designed for the front-office business applications software market. This market is highly competitive, rapidly changing, and significantly affected by new product introductions and the activities of other market participants. Our products are specifically targeted at the CRM market, as well as the markets for business analytics and customer data integration. We face competition primarily from our customers' internal information technology departments and systems integrators, as well as other application software providers that offer a variety of products and services designed to address these markets. We may not be able to compete successfully against such internal development efforts.

Our customers and prospective customers are increasingly evaluating their software procurement needs with a focus on the long-term total cost of ownership, which includes the cost of the license and the related professional services, such as implementation, training and technical support. With significantly lower license costs from competitive solutions, and no license cost for internal projects, our success depends on our ability to adequately communicate our strengths in the relative capabilities of our products, the total cost of ownership of the various alternative solutions, and the total return on investment of each of these alternatives.

The following is a discussion of the competitive environments in which we operate:

There are many factors that may increase competition in the business applications software market, including (i) entry of new competitors, (ii) alliances among existing competitors, (iii) alliances between our competitors and systems integrators, (iv) consolidation in the software industry or among systems integrators, and (v) technological changes or changes in the use of the Internet. Increased competition may result in price reductions, reduced gross margins or loss of market share, any of which could materially and adversely affect our business, financial condition or results of operations. We may not be able to compete successfully against current and future competitors or competitive pressures faced by us may materially and adversely affect our business, financial condition or results of operations.

Many leading companies in the market for business applications software have been the subject of mergers, acquisitions and divestitures during the last several years. For example, Oracle Corporation completed its acquisition of PeopleSoft, Inc. during the fourth quarter of 2004. We expect this trend towards consolidation to continue as companies attempt to maintain or extend their market and competitive positions in the rapidly changing business applications software industry and as companies are acquired or are unable to continue operations. This industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers. This could lead to more variability in our operating results due to lengthening of the customer evaluation process and/or loss of business to these stronger competitors, which may materially and adversely affect our business, financial condition or results of operations.

Our performance depends on the continued service of our key technical, sales and senior management personnel. Our key employees have not entered into employment agreements with a specified term of employment with us. The loss of one or more of our senior management personnel could have a material adverse effect on our business, financial condition or results of operations. In particular, in April 2005, upon mutual agreement between ourselves and J. Michael Lawrie, Mr. Lawrie resigned as our Chief Executive Officer and our Board of Directors appointed George T. Shaheen as our Chief Executive Officer. In addition, in recent years, we have had members of our senior management announce their retirement or departure from our company. We replace these individuals with internal candidates and, if deemed appropriate, individuals from outside our organization. While our internal candidates understand our business model, they must learn a new position and take on additional or new responsibilities, which could take time and result in the disruption to our on-going operations. To integrate into our company, new senior personnel must spend a significant amount of time learning our business model and management systems, in addition to performing their regular duties. Accordingly, until new senior personnel become familiar with our business model and systems, their integration may result in some disruption to our on-going operations. Additionally, we may need to hire additional personnel in general or to replace internal candidates who have been promoted and as a result, we may experience increased compensation costs that are not offset by either improved productivity or higher prices.

We continue to rely heavily on our direct sales force. In recent years, we have restructured or made other adjustments to our sales force in response to factors such as management changes, product changes and other internal considerations. Changes in the structure of the sales force and sales force management have resulted in a temporary lack of focus and reduced productivity that may have affected revenues in one or more quarters. If we continue to restructure our sales force, then the transition issues associated with restructuring the sales force may recur. Such restructuring or associated transition issues can be disruptive and adversely impact our business and operating results.

Software products frequently contain errors or failures, especially when first introduced or when new versions are released, and can be affected by viruses. We have in the past been, and may in the future be, forced to delay the commercial release of products until the software problems have been corrected. We could lose revenues as a result of software viruses, errors or defects, including defects in third-party products with which our products work. Our products are intended for use in applications that may be critical to a customer's business. As a result, we expect that our customers and potential customers will have a greater sensitivity to product defects than the market for software products generally. Testing errors may also be found in new products or releases after commencement of commercial shipments, resulting in loss of revenue or delay in market acceptance, damage to our reputation, or increased service and warranty costs, any of which could have a material adverse effect upon our business, financial condition or results of operations.

We rely primarily on a combination of patent, copyright, trade secret and trademark laws, confidentiality procedures and contractual provisions to protect our proprietary rights in our products. We also believe that the technological and creative skills of our personnel, new product developments, frequent product enhancements, name recognition and reliable product maintenance are essential to establishing and maintaining a technology leadership position. We seek to protect our software, documentation and other written materials under patent, trade secret and copyright laws, which afford only limited protection. Any patents issued to us may be invalidated, circumvented or challenged. Any of our pending or future patent applications, whether or not being currently challenged, may not be issued with the scope of the claims we seek, if at all. Furthermore, others may develop technologies that are similar or superior to our technology or design around our patents.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. Policing unauthorized use of our proprietary rights is difficult. In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. Our means of protecting our proprietary rights in the United States or abroad may not be adequate. We have entered into agreements with substantially all of our customers that require us to place Siebel Business Applications source code into escrow. Such agreements generally provide that such parties will have a limited, non-exclusive right to use such code if (i) there is a bankruptcy proceeding by or against us, (ii) we cease to do business, or (iii) we fail to meet our support obligations.

Although we do not believe that we are infringing any proprietary rights of others, third parties may claim that we have infringed their proprietary rights. Furthermore, former employers of our former, current or future employees may assert claims that such employees have improperly disclosed to us the confidential or proprietary information of such former employers. Any such claims, with or without merit, could (i) be time-consuming to defend, (ii) result in costly litigation, (iii) divert management's attention and resources, (iv) cause product shipment delays, and (v) require us to pay monetary damages or enter into royalty or licensing agreements. A successful claim of product infringement against us and our failure or inability to license or create a workaround for such infringed or similar technology may materially and adversely affect our business, financial condition or results of operations.

Our revenues are primarily derived from large multinational companies. To service the needs of these companies, we must provide worldwide product support services. We have expanded and in the future may expand our international operations and enter additional international markets. This will require significant management attention and financial resources that could adversely affect our operating margins and earnings. We may not be able to maintain or increase international market demand for Siebel Business Applications and our OnDemand solutions. If we do not, our international sales will be limited and our business, financial condition or results of operations could be materially and adversely affected.

Our international operations are subject to a variety of risks, including (i) foreign currency fluctuations, (ii) economic or political instability, (iii) shipping delays, and (iv) various trade restrictions. Any of these risks could have a significant impact on our ability to deliver products on a competitive and timely basis. Significant increases in the level of customs duties, export quotas or other trade restrictions could also have an adverse effect on our business, financial condition or results of operations. In situations where direct sales or purchases are denominated in foreign currency, any fluctuation in the exchange rate may adversely affect our business, financial condition or results of operations. Generally, we manage our foreign currency exchange rate risk by entering into contracts to sell or purchase foreign currency at the time a foreign currency receivable or payable is generated. When the foreign currency asset or liability is extinguished, the contract is liquidated, and the resulting gain or loss on the contract mitigates the exchange rate risk of the associated asset or liability. In certain instances, we have not hedged foreign currency receivables and payables when the forward contracts in the relevant currency were not readily available or were not cost-effective.

The trading price of our common stock has fluctuated substantially since our initial public offering in June 1996. The trading price is subject to significant fluctuations in response to (i) variations in quarterly operating results; (ii) the gain or loss of significant orders; (iii) changes in earnings estimates by analysts; (iv) changes in our revenue and/or earnings expectations as announced in our earnings calls; (v) announcements of technological innovations or new products by us or our competitors; (vi) changes in domestic and international economic, political and business conditions; (vii) general conditions in the software and computer industries; (viii) the recent lack of public confidence in corporate governance and accounting practices; and (ix) other events or factors. In addition, the stock market in general has experienced extreme price and volume fluctuations that have affected the market prices for many companies in industries similar or related to ours and that have been unrelated to the operating performance of these companies. These market fluctuations have adversely affected and may continue to adversely affect the market price of our common stock.

Our Board of Directors is authorized to issue up to 2,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further approval by our stockholders. One of these shares has been designated Series A1 Preferred Stock, which was issued in connection with the acquisition of Janna Systems Inc. in 2000, and 100,000 shares have been designated as Series A2 Junior Participating Preferred Stock, which were authorized in connection with a stockholders' rights plan that we implemented in 2003. Additional shares of preferred stock could be authorized or issued with voting, liquidation, dividend and other rights superior to those of the common stock.

The rights of the holders of common stock will be subject to and may be adversely affected by the rights of the holders of any preferred stock that has already been authorized or issued, or that may be issued in the future. The issuance of the Series A2 Junior Participating Preferred Stock or the authorization of additional classes of preferred stock by our Board of Directors in the future, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could make it more difficult for a third party to acquire a majority of our outstanding voting common stock. In addition, the following factors could also delay or make more difficult a merger, tender offer or proxy contest: (i) our classified Board of Directors, (ii) certain provisions of our certificate of incorporation, (iii) certain provisions of our bylaws, and (iv) certain provisions of Delaware law.
