The MicroStrategy mission is to empower every business user to make more informed decisions by providing timely, relevant, and accurate answers to their business questions. To achieve this mission, MicroStrategy’s single, integrated platform is designed to support various styles of business intelligence through an easy-to-use interface. MicroStrategy provides sophisticated analytical performance to every business user in the format that suits them best, from high-level dashboards to custom reports and advanced analysis via e-mail, web, fax, wireless and voice communication channels. MicroStrategy engineers its software for reliability, scalability, security and ease of administration for organizations of all sizes.

Our software platform, MicroStrategy 8^TM, enables users to query and analyze the most detailed, transaction-level databases, turning data into business intelligence and delivering boardroom quality reports and alerts about the users’ business processes. Our web-based architecture provides reporting, security, performance and standards that are critical for web deployment.

Leading companies and government organizations worldwide have chosen MicroStrategy as their enterprise business intelligence standard. By integrating information from across the enterprise, solutions built on the MicroStrategy platform are designed to give analysts, managers and executives the critical insight they need to make better business and management decisions and to optimize their operations. With extranet deployments, enterprises can use MicroStrategy 8 to build stronger relationships by linking customers and suppliers via the Internet. MicroStrategy facilitates customer success with a comprehensive offering of consulting, education, technical support and technical advisory services for our customers and strategic partners.

Industry Background

Business intelligence software offers decision-makers the opportunity to ask and answer questions about their use of data that has been captured but not yet fully exploited.

Four key business needs have driven demand for business intelligence tools:

• Increased User Access and Scalability:    In the past, dissemination of information has been limited to a few power users or analysts. Now a wide range of information customers—from customer service representatives to the CEO and from customers to suppliers—demand and can benefit from the insight that business intelligence can provide. The wide acceptance of the Internet as an information source also has fueled demand for enterprise data to be accessible over the web to tens of thousands of users across the enterprise.

• Increased Data Scalability:    Increasing information generation, and in particular, the need to capture electronically and store every business transaction has made terabyte-size data warehouses commonplace. Terabyte-size data warehouses store one trillion bytes of data or more and are among the largest databases in the world. Since transaction-level information is now routinely captured, organizations can struggle to make productive use of such massive data stores. Organizations need to view data within the operational context of the data—making even the most detailed information meaningful and comprehensive to business users. As a result, users want to be able to discover easily trends hidden in these very large databases, and verify these trends by reviewing the underlying transaction detail.

• Improved Supply Efficiency:    Supplier transactions become more efficient with direct access to inventory and other related data. For true vendor-managed inventory and collaborative commerce

3

systems, vendors need to have access to key information about how their products are performing against business metrics. For example, vendors should be able to see how their products are selling in each geographic region so as not to over-ship products that are slow-moving or under-ship products that are selling quickly. By opening vendor performance information to the vendors themselves, buyers and sellers of goods and services become partners in the quest to optimize sales, margin and inventory.

• Improved Distribution Efficiency:    Business partners collaborate more effectively with access to shared data. By granting partners access to information such as the manufacturing pipeline and build schedule, partners can be more effective at satisfying demands of end customers and setting expectations. Furthermore, opening invoice and purchase order information to partners can enable them to reduce the overhead associated with channel management, resulting in cost savings and time efficiencies. For example, notifying channel sales partners of changes in the manufacturing schedule allows them to reset end customer expectations or to increase selling activity.

The emergence and widespread acceptance of the Internet as a medium of communication and commerce have changed the way businesses interact with each other and their customers by allowing businesses to establish new revenue streams, create new distribution channels and reduce costs. Simultaneously, the amount of corporate information stored in databases continues to grow exponentially, and companies are giving an increasing number of employees, customers and partners access to their information. Business intelligence tools are one of the gateways to this information. For example, companies are using Internet-based systems to facilitate business operations, including sales automation, supply-chain management, marketing, customer service and human resource management. Consumers are also becoming increasingly sophisticated in their use of the Internet, relying on the Internet not only to make online purchases, but to perform price comparisons, analyze recommendations from like-minded individuals, educate themselves about relevant products and offerings and enter into transactions that were once conducted face-to-face or via the telephone. The integration of the Internet into business processes and increased consumer sophistication create opportunities for companies to use business intelligence applications as part of a more dynamic business model. Factors driving demand for these applications include:

Increased Electronic Capture of Transaction, Operational and Customer Information.    The rapid growth in the electronic capture of business information and the increased availability of related profile data on the parties or products involved in each transaction are providing businesses with a rich data foundation for performing various analyses and making decisions. Powerful data analysis and mining tools are required to sift through massive amounts of data to uncover information regarding customer interactions, trends, patterns and exceptions, in turn enabling organizations to provide superior service and products to customers.

Need to Create a Personalized, One-to-One Customer and/or Supplier Experience While Maintaining Privacy.    Many companies are initiating strategies that establish personalized relationships with each customer and/or supplier based on individual needs and preferences, and earn their loyalty by providing superior service, security and convenience. In order to successfully acquire, retain and upgrade customers, organizations need to understand their profiles, their transaction history, their past responses to marketing campaigns, and their interactions with customer service. Retrieving information from widely dispersed and complex data sources and providing a holistic view of the customer can be challenging. At the same time, while businesses have the opportunity to collect a variety of information that could improve targeting, customers are increasingly concerned about the potential for loss or abuse of their privacy.

Need to Integrate Online and Traditional Operations.    While there are substantial benefits to conducting business electronically, companies need to ensure that their online operations work in combination with their traditional operations. Companies are seeking to ensure that an order placed online can be reliably fulfilled according to the expectations of the customer and to develop and maintain consistent interactions with customers across different channels. Maintaining the integrity of, and enhancing, the customer experience are crucial to fostering customer loyalty and supply chain relationships.

4

Increased Openness of Business Intelligence Applications to Customers, Suppliers and Partners.    Business intelligence systems are no longer confined to the organization. Today, companies are extending their business intelligence insight to suppliers, channel partners and customers via extranets. Business partners can have up-to-the-minute access to sales histories, inventory status and billing information through their web browsers.

Emergence of Wireless Internet and Voice Technologies.    Information can be more valuable if there is untethered, ubiquitous access to the information. An integrated platform reduces the need to rely on multiple vendors for these products and services. This development is expected to generate new business opportunities for companies by providing an additional channel for existing services and creating opportunities to provide new services that can be delivered to any place and at any time to anyone that has access to a wireless device.

MicroStrategy Solution: Business Intelligence for the Whole Enterprise

MicroStrategy offers MicroStrategy 8, an integrated, industrial-strength business intelligence platform designed to enable organizations to consolidate business intelligence applications onto a single platform for reporting, analysis and monitoring of real-time business information. The platform provides reliable and maintainable solutions with a low total cost of ownership and can be used in departmental, enterprise or extranet deployments. The MicroStrategy 8 business intelligence platform can be used to identify trends, improve operational efficiencies, reduce costs and increase profitability. Since businesses integrate information from across the enterprise, solutions built on the MicroStrategy 8 platform give analysts, managers and executives critical insight they need in optimizing their business operations. Integrated web-based reporting, report delivery and real-time alerting capabilities can enable the entire enterprise to work smarter, faster and better.

MicroStrategy’s business intelligence platform provides the functionality users need to make better business and management decisions. The MicroStrategy 8 platform delivers a high-performance solution that meets users’ demands and is highly functional, simple to use, scalable and easy to administer. With one platform, users are able to report, analyze and monitor their business with all of the five most popular styles of business intelligence, which consist of:

1. Scorecards and Dashboards—Reports are formatted with broad visual appeal and can easily convey information “at-a-glance”. This style of business intelligence targets the business monitoring needs of managers and executives.

2. Reporting—Report formats can have more detailed operational information than is conveyed on a scorecard or dashboard. These reports serve critical information to all personnel across the enterprise.

3. OLAP Analysis—Slice-and-dice analysis with drilling, pivoting, page-by and sorting capabilities serves business users whose analytical needs exceed the content of the operational reports and require a simple environment for basic exploration within a limited range of data.

4. Advanced and Predictive Analysis—Investigative queries that can analyze data in the database, down to the transaction level detail if necessary. This style provides extensive predictive and statistical treatment of the data for correlation analysis, trend analysis, financial analysis and projections.

5. Alerts and Proactive Reporting—Information that needs continuous monitoring requires alerts and proactive reporting to serve large populations on set schedules, business exceptions or on-demand. This style of business intelligence targets large user populations both internal and external to the enterprise.

Specific benefits of the MicroStrategy 8 business intelligence platform include:

Flexibility to Report, Analyze and Monitor.    MicroStrategy’s business intelligence platform unifies reporting, analysis and real-time business monitoring into one experience for the business user, one efficient and scalable architecture for the IT professional, and one economical and extensible utility for the CIO.

5

Industrial-Strength Business Intelligence.    The MicroStrategy platform enables industrial-strength business intelligence with enterprise-caliber IT, high user scalability and high database scalability. MicroStrategy enables centralized administration, operations and operations maintenance in a unified interface and unified backplane. This enterprise-caliber infrastructure allows for data scalability and user scalability with a zero footprint web product, where business intelligence can expand across and grow with the enterprise.

Five Styles of Business Intelligence.    Through MicroStrategy’s integration of the five styles of business intelligence, users are no longer bound to departmental reporting or solutions that offer only one style of business intelligence or combine individual styles of business intelligence. The need for multiple business intelligence or reporting tools is minimized when users have access to all five styles for their enterprise business intelligence needs.

Easy-to-use Interface for Business Users.    MicroStrategy exposes all the sophisticated business intelligence applications to end users through easy to use intuitive what-you-see-is-what-you-get (WYSIWYG) web interfaces. This enables deployment to large user populations with minimal training required. The user interface includes an array of “one-click” actions embedded throughout the interface. It uses dialog boxes, mouse-over tool tips, and undo/redo buttons to make it easy for business people to explore the software without prior training.

Interactive Reporting.    MicroStrategy 8 has extended the MicroStrategy reporting capability by making all reports and scorecards fully interactive. Business users can rearrange the organization of any report with simple drag-n-drop actions or by clicking on the toolbar icons to get views of the data, all from the same report and without requiring assistance from IT.

Integration of Analysis in Every Report or Scorecard.    MicroStrategy 8 makes the same powerful analytic capability available directly from enterprise reports or scorecards automatically. MicroStrategy 8 delivers analytic integration to reporting users in two ways. The first is by providing on-line analytical processing (OLAP) capabilities directly to tables embedded within report documents, allowing business users to analyze the data within the table while staying within the bigger report document. The second way allows users to “drill” from a report document to a dedicated analysis view that is optimized for conducting detailed analysis. In both cases, the integration of reporting with analysis is automatic.

Direct Access to SAP^® BW, Microsoft Analysis Services™ and Hyperion^® Essbase™.    MicroStrategy 8 incorporates a dynamic data access engine designed to access multi-dimensional databases (MDDBs or OLAP Cube Databases), such as those from SAP Business Warehouse (BW), Microsoft Analysis Services and Hyperion Essbase.

MicroStrategy 8’s Dynamic Multi-Dimensional Expressions (MDX) Engine generates MDX syntax that is fully certified with SAP BW using SAP’s high performance Business API interfaces. Because MicroStrategy’s MDX is dynamically generated using the multidimensional models implicit in SAP InfoCubes, QueryCubes and ODS databases, users can automatically and transparently drill back into SAP BW for more data, without any prior programming or prior design of drill paths. MicroStrategy 8 can also join data across SAP BW Infocubes and QueryCubes as well as access multiple instances of SAP BW and non-SAP sources at once.

In addition, MicroStrategy 8’s Dynamic MDX Engine generates MDX syntax against Microsoft Analysis Services and Hyperion Essbase using the XMLA (XML for Analysis) standard for communication. XMLA is a new standard for accessing multidimensional data jointly developed by members of the XMLA council. As with SAP BW, MicroStrategy’s MDX is dynamically generated using the multidimensional models implicit in Microsoft Analysis Services and Hyperion Essbase cubes. Because of this, users can automatically drill back to underlying source data without any additional programming or drill-path design.

Users of SAP BW, Microsoft Analysis Services and Hyperion Essbase databases each can access these reports through all of the MicroStrategy interfaces, MicroStrategy Web, Office, Narrowcast Server, and Desktop, just like any other MicroStrategy report. These reports offer standard OLAP functionality including graphing, subtotals, pivot, sort and page-by.

6

Direct Access to Operational Data From Enterprise Resource Planning (ERP) Systems.    MicroStrategy 8 extends the MicroStrategy metadata architecture to include attributes and facts accessed directly from non-modeled databases, instantly on a query-by-query basis. MicroStrategy 8’s Operational SQL Engine enables MicroStrategy reports to include data from any operational system using either completely free-form structured query language (SQL) or a graphical query builder interface, including stored procedures and views. Since the attributes and facts from operational database sources are managed by the MicroStrategy metadata architecture, MicroStrategy’s security architecture and other reusable objects such as prompts can be applied automatically.

Heterogeneous Joining of Data From Across the Enterprise.    MicroStrategy 8 extends the MicroStrategy data modeling flexibility to include integrated views of data across heterogeneous data stores. By mapping conforming dimensions from different sources within the MicroStrategy object model, MicroStrategy 8 can automatically join data from multiple different sources in the same report document. Data can come from any source accessible by MicroStrategy 8, including the data warehouse, data marts, SAP BW, Microsoft Analysis Services, Hyperion Essbase and any number of operational system databases.

Integrating Data Mining into Mainstream Reports & Analyses.    MicroStrategy 8 extended its analytic engine by allowing reports and analyses to include predictive capabilities in every MicroStrategy report or analysis. MicroStrategy 8’s analytic engine can calculate four of the primary data mining functions, including neural network algorithms, clustering algorithms, regression algorithms, and tree algorithms. Hand-in-hand with this calculation capability, MicroStrategy 8 also includes the ability to import data mining models directly from data mining products from vendors like IBM^®, Teradata^®, SAS, and SPSS using the predictive modeling mark-up language standard. With this capability, data mining models can be imported through a single click and automatically converted into a standard MicroStrategy metric. After that, MicroStrategy’s Data Mining Service extension enables these metrics to be used freely and calculated quickly in reports, analyses and alerts.

Support for Large Data Volumes and All Major Relational Database/Hardware Combinations.    The MicroStrategy platform supports systems with very large data volumes and is specifically optimized to support all major relational database platforms commonly used for business intelligence systems as well as multi-dimensional databases like SAP BW. Important features of our solution in this area include:

• SQL optimization drivers that improve performance of each major database;

• The ability to support very large user populations;

• Highly reliable up-time, even in high volume applications; and

• The ability to work with and support nine languages for international applications.

Powerful Analytics to Customer- and Transaction-Levels of Detail.    We believe that the MicroStrategy 8 platform incorporates one of the most sophisticated analysis engines available today, capable of answering highly detailed business questions. It offers support for information beyond the summary level to include information at the customer- and transaction- levels. This capability is critical to a wide range of applications, including highly targeted direct marketing, e-commerce site personalization, customer and product affinity analysis, call detail analysis, fraud detection, credit analysis forecasting, trend metrics and campaign management. The MicroStrategy 8 platform allows the creation of highly sophisticated systems that take maximum advantage of the detail available in a company’s databases.

Powerful Personalization Engine.    The MicroStrategy 8 platform includes a customer- and transaction-level personalization engine. The underlying architecture is designed to generate personalization parameters based on data gathered by an organization from a variety of sources, including past customers’ transactions, customer clickstream information, stated user preferences and demographic information. In addition, the MicroStrategy personalization engine is able to determine when and under what circumstances a person is automatically provided with a set of information that proves useful in fraud detection and homeland security applications.

7

Powerful Narrowcast Server Distribution Engine for Information Delivery.    Our technology offers a high performance personalized narrowcast engine for delivering periodic and alert-based information to users via Internet, e-mail, wireless devices, printer and fax. The narrowcast engine includes drivers for all major device types used in both domestic and international markets, enabling the delivery of information to users when and where it is needed.

Highly Stylized and Consolidated Reporting and Formatting Capabilities.    MicroStrategy Report Services™ technology delivers a wide range of enterprise reports via the web, including production and operational reports, managed metrics reports and scorecards. The design capabilities provide the precision necessary to deliver reports with boardroom presentation quality, without any programming. By dragging and dropping report components, users can create high quality reports with complete formatting flexibility. Unlike other popular reporting products, the modern architecture delivers both traditional hierarchical banded reports and newer, web-oriented zone-based reports.

Competition

The market for business intelligence software is intensely competitive and subject to rapidly changing technology. In addition, many companies in these markets are offering, or may soon offer, products and services that may compete with MicroStrategy products.

MicroStrategy faces competitors in several broad categories, including business intelligence software, analytical processes, query and web-based reporting tools, and report delivery. Our competitors that are primarily focused on business intelligence products include, among others, Actuate, Business Objects, Cognos, Hyperion Solutions, Information Builders, and the SAS Institute. We also compete with large software corporations, including suppliers of enterprise resource planning software that provide one or more capabilities competitive with our products, including IBM, Microsoft, Oracle, SAP AG and others.

Many of our competitors have longer operating histories, significantly greater financial, technical, marketing or other resources, and greater name recognition than we do. In addition, many of our competitors have strong relationships with current and potential customers and extensive knowledge of the business intelligence industry. As a result, they may be able to respond more quickly to new or emerging technologies and changes in customer requirements or devote greater resources to the development, promotion and sale of their products than we can. Increased competition may lead to price cuts, reduced gross margins and loss of market share. We may not be able to compete successfully against current and future competitors, and the failure to meet the competitive pressures we face may have a material adverse effect on our business, operating results and financial condition.

Current and future competitors may also make strategic acquisitions or establish cooperative relationships among themselves or with others. By doing so, they may increase their ability to meet the needs of our potential customers. Our current or prospective indirect channel partners may establish cooperative relationships with our current or future competitors. These relationships may limit our ability to sell our products through specific distribution channels. Accordingly, new competitors or alliances among current and future competitors may emerge and rapidly gain significant market share. These developments could limit our ability to obtain revenues from new customers and to maintain product support and other services revenue from our installed customer base.

Research and Product Development

We have made, and continue to make, substantial investments in research and product development. We believe that our future performance will depend in large part on our ability to maintain and enhance our current product line, develop new products that achieve market acceptance, maintain technological competitiveness and meet an expanding range of customer requirements. As of December 31, 2005, our research and product development staff consisted of 226 employees, 209 of whom are working on our core business intelligence projects and 17 of whom are working on research and development relating to our non-core businesses.

16

Employees

As of December 31, 2005, we had a total of 1,005 employees, of whom 689 were based in the United States and 316 were based internationally. Of the total of 1,005 employees, 334 were engaged in sales and marketing, 226 in research and development, 250 in technical support, consulting and education services, and 195 in finance, administration and corporate operations. None of our employees is represented by a labor union. We have not experienced any work stoppages and consider our relations with our employees to be good.

We believe that effective recruiting, education and nurturing of human resources are critical to our success and have traditionally made investments in these areas in order to differentiate ourselves from our competition, increase employee loyalty and create a culture conducive to creativity, cooperation and continuous improvement.

All newly hired technical and sales professionals complete a professional orientation course that ranges from one day to four weeks long, presented by “MicroStrategy University,” our in-house education function. The curriculum consists of lectures, problem sets and independent and group projects, covering data on our products, competitors and customers. Certain lectures also deal with general business practices, ethics and teamwork. Throughout this training, students typically must pass a number of oral and written examinations in order to begin their assignments. Course content for MicroStrategy University is created by experienced members of our professional staff, who generally have an annual obligation to update course content based upon the best practices they have most recently observed in the field. This expert content is then used to upgrade and revitalize our education, consulting, support, technology and marketing operations.

ITEM 1A.    RISK FACTORS

You should carefully consider the risks described below before making an investment decision. The risks and uncertainties described below are not the only ones facing MicroStrategy. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected. In such case, the trading price of our class A common stock could decline and you may lose all or part of your investment.

Our quarterly operating results, revenues and expenses may fluctuate significantly, which could have an adverse effect on the market price of our stock

For a number of reasons, including those described below, our operating results, revenues and expenses have in the past varied and may in the future vary significantly from quarter to quarter. These fluctuations could have an adverse effect on the market price of our class A common stock.

Fluctuations in Quarterly Operating Results.    Our quarterly operating results may fluctuate, in part, as a result of:

• the size, timing, volume and execution of significant orders and shipments;

• the mix of products and services of customer orders, which can affect whether we recognize revenue upon the signing and delivery of our software products or whether revenue must be recognized as work progresses or over the entire contract period;

17

• the timing of new product announcements by us or our competitors;

• changes in our pricing policies or those of our competitors;

• market acceptance of business intelligence software generally and of new and enhanced versions of our products in particular;

• the length of our sales cycles;

• changes in our operating expenses;

• personnel changes;

• our use of direct and indirect distribution channels;

• utilization of our consulting and education services, which can be affected by delays or deferrals of customer implementation of our software products;

• changes in foreign currency exchange rates;

• our profitability and expectations for future profitability and its effect on our deferred tax assets and net income for the period in which any adjustment to our net deferred tax asset valuation allowance may be made;

• seasonal factors, such as our traditionally lower pace of new sales in the summer; and

• changes in customer budgets.

Limited Ability to Adjust Expenses.    We base our operating expense budgets on expected revenue trends. Many of our expenses, such as office leases and certain personnel costs, are relatively fixed. We may be unable to adjust spending quickly enough to offset any unexpected revenue shortfall. Accordingly, any shortfall in revenue may cause significant variation in operating results in any quarter.

Based on the above factors, we believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance. It is possible that in one or more future quarters, our operating results may be below the expectations of public market analysts and investors. In that event, the trading price of our class A common stock may fall.

The trading price for our class A common stock has been and may continue to be volatile

The trading price of our class A common stock historically has been volatile and may continue to be volatile. The trading price of our class A common stock may fluctuate widely in response to various factors, some of which are beyond our control. These factors include:

• quarterly variations in our results of operations or those of our competitors;

• announcements by us or our competitors of acquisitions, new products, significant contracts, commercial relationships or capital commitments;

• the emergence of new sales channels in which we are unable to compete effectively;

• our ability to develop and market new and enhanced products on a timely basis;

• commencement of, or our involvement in, litigation;

• any major change in our board or management;

• changes in governmental regulations or in the status of our regulatory approvals;

• recommendations by securities analysts or changes in earnings estimates;

• announcements about our earnings that are not in line with analyst expectations, the likelihood of which may be enhanced because it is our policy not to give guidance relating to our anticipated financial performance in future periods;

18

• announcements by our competitors of their earnings that are not in line with analyst expectations;

• the volume of shares of class A common stock available for public sale;

• sales of stock by us or by our stockholders;

• short sales, hedging and other derivative transactions involving shares of our class A common stock; and

• general economic conditions and slow or negative growth of related markets.

In addition, the stock market in general, and the market for technology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. These broad market and industry factors may seriously harm the market price of our class A common stock, regardless of our actual operating performance.

We face the risk of a decrease in our cash balances and losses in our investment portfolio

Our cash balances are held in numerous locations throughout the world. A portion of our cash is invested in marketable securities as part of our investment portfolio. Among other factors, changes in interest rates, foreign currency fluctuations and macroeconomic conditions could cause our cash balances to fluctuate and losses in our investment portfolio. Most amounts held outside the United States could be repatriated to the United States, but, under current law, would be subject to U.S. federal income tax, less applicable foreign tax credits.

Revenue recognition accounting pronouncements may adversely affect our reported results of operations

We continuously review our compliance with all new and existing revenue recognition accounting pronouncements. Depending upon the outcome of these ongoing reviews and the potential issuance of further accounting pronouncements, implementation guidelines and interpretations, we may be required to modify our reported results, revenue recognition policies or business practices, which could have a material adverse effect on our results of operations. Our existing revenue recognition policies are described in Note 2 to our Consolidated Financial Statements and in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies—Revenue Recognition.”

We may have exposure to greater than anticipated tax liabilities

We are subject to income taxes and non-income taxes in a variety of jurisdictions and our tax structure is subject to review by both domestic and foreign taxation authorities. The determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment. Moreover, in the ordinary course of a global business, there are many intercompany transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.

If the market for business intelligence software fails to grow as we expect, or if businesses fail to adopt our products, our business, operating results and financial condition could be materially adversely affected

Nearly all of our revenues to date have come from sales of business intelligence software and related technical support, consulting and education services. We expect these sales to account for a large portion of our revenues for the foreseeable future. Although demand for business intelligence software has grown in recent years, the market for business intelligence software applications is still emerging. Resistance from consumer and privacy groups to increased commercial collection and use of data on spending patterns and other personal behavior and European and other governmental restrictions on the collection and use of personal data may impair the further growth of this market, as may other developments. We cannot be sure that this market will continue to

19

grow or, even if it does grow, that businesses will adopt our solutions. We have spent, and intend to keep spending, considerable resources to educate potential customers about business intelligence software in general and our solutions in particular. However, we cannot be sure that these expenditures will help our products achieve any additional market acceptance. If the market fails to grow or grows more slowly than we currently expect, our business, operating results and financial condition would be materially adversely affected.

Business disruptions could affect our operating results

A significant portion of our research and development activities and certain other critical business operations are concentrated in a single geographic area. We are also a highly automated business and a disruption or failure of our systems could cause delays in completing sales and providing services. A major earthquake, fire, act of terrorism or other catastrophic event that results in the destruction or disruption of any of our critical business operations or information technology systems could severely affect our ability to conduct normal business operations and as a result our future operating results could be materially and adversely affected.

We use strategic channel partners and if we are unable to maintain successful relationships with them, our business, operating results and financial condition could be materially adversely affected

In addition to our direct sales force, we use strategic channel partners such as value-added resellers, system integrators and original equipment manufacturers to license and support our products. For the years ended December 31, 2005, 2004 and 2003 channel partners accounted for 21.8%, 19.3% and 24.6%, respectively, of our total product licenses revenues. Our channel partners generally offer customers the products of several different companies, including products that compete with ours. Because our channel partners generally do not have an exclusive relationship with us, we cannot be certain that they will prioritize or provide adequate resources to selling our products. Moreover, divergence in strategy or contract defaults by any of these channel partners may materially adversely affect our ability to develop, market, sell or support our products.

Although we believe that direct sales will continue to account for a majority of product licenses revenues, we seek to maintain a significant level of indirect sales activities through our strategic channel partners. There can be no assurance that our strategic partners will continue to cooperate with us when our distribution agreements expire or are up for renewal. In addition, there can be no assurance that actions taken or omitted to be taken by such parties will not adversely affect us. Our ability to achieve revenue growth in the future will depend in part on our success in maintaining successful relationships with our strategic partners. If we are unable to maintain our relationships with these strategic partners, our business, operating results and financial condition could be materially adversely affected.

Our recognition of deferred revenue and advance payments is subject to future performance obligations and may not be representative of revenues for succeeding periods

Our current and long-term deferred revenue and advance payments were $47.4 million as of December 31, 2005. The timing and ultimate recognition of our deferred revenue and advance payments depend on various factors, including our performance of various service obligations. Because of the possibility of customer changes in development schedules, delays in implementation and development efforts and the need to satisfactorily perform product support services, deferred revenue and advance payments at any particular date may not be representative of actual revenue for any succeeding period.

We may not be able to sustain or increase profitability in the future

We generated net income for the fiscal years ended December 31, 2005 and 2004; however, we may not be able to sustain or increase profitability on a quarterly or annual basis in the future. As of December 31, 2005, our accumulated deficit was $112.9 million. If operating expenses exceed our expectations or cannot be adjusted accordingly or revenues fall below our expectations, our business, results of operations and financial condition

20

may be materially and adversely affected. We have significant deferred tax assets, and if we are unable to sustain profitability, we may be required to establish a valuation allowance against these deferred tax assets, which would result in a charge that would adversely affect net income in the period in which the charge is incurred.

Managing our international operations is complex and our failure to do so successfully or in a cost-effective manner could have a material adverse effect on our business, operating results and financial condition

We receive a significant portion of our total revenues from international sales from foreign direct and indirect operations. International sales accounted for 38.4%, 40.7% and 34.0% of our total revenues for the years ended December 31, 2005, 2004 and 2003, respectively. Our international operations require significant management attention and financial resources.

There are certain risks inherent in our international business activities including:

• changes in foreign currency exchange rates;

• unexpected changes in regulatory requirements;

• tariffs, export restrictions and other trade barriers;

• costs of localizing products;

• lack of acceptance of localized products;

• longer accounts receivable payment cycles;

• difficulties in and costs of staffing, managing and operating our international operations;

• tax issues, including restrictions on repatriating earnings;

• weaker intellectual property protection;

• economic weakness or currency related crises;

• the burden of complying with a wide variety of laws (including labor laws);

• generally longer payment cycles and greater difficulty in collecting accounts receivable;

• our ability to adapt to sales practices and customer requirements in different cultures; and

• political instability in the countries where we are doing business.

These factors may have a material adverse effect on our future international sales and, consequently, on our business, operating results and financial condition.

We may lose sales, or sales may be delayed, due to the long sales and implementation cycles for our products, which could reduce our revenues

To date, our customers have typically invested substantial time, money and other resources and involved many people in the decision to license our software products and purchase our consulting and other services. As a result, we may wait nine months or more after the first contact with a customer for that customer to place an order while it seeks internal approval for the purchase of our products and/or services. During this long sales cycle, events may occur that affect the size and/or timing of the order or even cause it to be canceled. For example, our competitors may introduce new products, or the customer’s own budget and purchasing priorities may change.

Even after an order is placed, the time it takes to deploy our products and complete consulting engagements can vary widely. Implementing our product can take several months, depending on the customer’s needs, and may begin only with a pilot program. It may be difficult to deploy our products if the customer has complicated

21

deployment requirements, which typically involve integrating databases, hardware and software from different vendors. If a customer hires a third party to deploy our products, we cannot be sure that our products will be deployed successfully.

Our customers include the U.S. government and a number of other U.S. state and local governments or agencies

Procurement.    Contracting with public sector customers is highly competitive and can be time-consuming and expensive, requiring that we incur significant upfront time and expense without any assurance that we will win a contract.

Budgetary Constraints and Cycles.    Demand and payment for our products and services are impacted by public sector budgetary cycles and funding availability, with funding reductions or delays adversely impacting public sector demand for our products and services.

Modification or Cancellation of Contracts.    Public sector customers often have contractual or other legal rights to terminate current contracts for convenience or due to a default. If a contract is cancelled for convenience, which can occur if the customer’s product needs change, we may only be able to collect for products and services delivered prior to termination. If a contract is cancelled because of default, we may only be able to collect for products and services delivered, and we may be forced to pay any costs incurred by the customer for procuring alternative products and services.

Governmental Audits.    U.S. government and other state and local agencies routinely investigate and audit government contractors. If these audits determine that we have failed to comply with any of the complex laws and regulations relating to the formation, administration and performance of government contracts, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of fees, fines and suspensions or debarment from future government business.

We face intense competition, which may lead to lower prices for our products, reduced gross margins, loss of market share and reduced revenue

The markets for business intelligence software, analytical applications and information delivery are intensely competitive and subject to rapidly changing technology. In addition, many companies in these markets are offering, or may soon offer, products and services that may compete with MicroStrategy products.

MicroStrategy faces competitors in several broad categories, including business intelligence software, analytical processes, query and web-based reporting tools, and report delivery. Our competitors that are primarily focused on business intelligence products include, among others, Actuate, Business Objects, Cognos, Hyperion Solutions, Information Builders and the SAS Institute. We also compete with large software corporations, including suppliers of enterprise resource planning software that provide one or more capabilities competitive with our products, including IBM, Microsoft, Oracle, SAP AG and others.

Many of our competitors have longer operating histories, significantly greater financial, technical, marketing or other resources, and greater name recognition than we do. In addition, many of our competitors have strong relationships with current and potential customers and extensive knowledge of the business intelligence industry. As a result, they may be able to respond more quickly to new or emerging technologies and changes in customer requirements or devote greater resources to the development, promotion and sale of their products than we can. Increased competition may lead to price cuts, reduced gross margins and loss of market share. We may not be able to compete successfully against current and future competitors and the failure to meet the competitive pressures we face may have a material adverse effect on our business, operating results and financial condition.

Current and future competitors may also make strategic acquisitions or establish cooperative relationships among themselves or with others. By doing so, they may increase their ability to meet the needs of our potential

customers. Our current or prospective indirect channel partners may establish cooperative relationships with our current or future competitors. These relationships may limit our ability to sell our products through specific distribution channels. Accordingly, new competitors or alliances among current and future competitors may emerge and rapidly gain significant market share. These developments could limit our ability to obtain revenues from new customers and to maintain technical support revenues from our installed customer base.

We depend on technology licensed to us by third parties, and the loss of this technology could impair our software, delay implementation of our products, or force us to pay higher license fees

We license third-party technologies that we incorporate into our existing products. There can be no assurance that the licenses for such third-party technologies will not be terminated or that we will be able to license third-party software for future products. In addition, we may be unable to renegotiate acceptable third-party license terms. Changes in or the loss of third party licenses could lead to a material increase in the costs of licensing or to our software products becoming inoperable or their performance being materially reduced, with the result that we may need to incur additional development costs to ensure continued performance of our products, and we may experience a decreased demand for our products.

We depend on revenue from a single suite of products

Our MicroStrategy 8 suite of products accounts for a substantial portion of our revenue. Because of this revenue concentration, our business could be harmed by a decline in demand for, or in the prices of, our MicroStrategy 8 software as a result of, among other factors, any change in our pricing model, increased competition, a maturation in the markets for these products or other risks described in this document.

If we are unable to recruit or retain skilled personnel, or if we lose the services of any of our key management personnel, our business, operating results and financial condition could be materially adversely affected

Our future success depends on our continuing ability to attract, train, assimilate and retain highly skilled personnel. Competition for these employees is intense. We may not be able to retain our current key employees or attract, train, assimilate or retain other highly skilled personnel in the future. Our future success also depends in large part on the continued service of key management personnel, particularly Michael J. Saylor, our Chairman, President and Chief Executive Officer, and Sanju K. Bansal, our Vice Chairman, Executive Vice President and Chief Operating Officer. If we lose the services of one or both of these individuals or other key personnel, or if we are unable to attract, train, assimilate and retain the highly skilled personnel we need, our business, operating results and financial condition could be materially adversely affected.

Pending or future litigation could have a material adverse impact on our results of operation and financial condition

In addition to intellectual property litigation, from time to time, we have been subject to other litigation. Where we can make a reasonable estimate of the liability relating to pending litigation and determine that it is probable, we record a related liability. As additional information becomes available, we assess the potential liability and revise estimates as appropriate. However, because of uncertainties relating to litigation, the amount of our estimates could be wrong. In addition to the related cost and use of cash, pending or future litigation could cause the diversion of management’s attention and resources.

If we are unable to develop and release product enhancements and new products to respond to rapid technological change in a timely and cost-effective manner, our business, operating results and financial condition could be materially adversely affected

The market for our products is characterized by rapid technological change, frequent new product introductions and enhancements, changing customer demands and evolving industry standards. The introduction

23

of products embodying new technologies can quickly make existing products obsolete and unmarketable. We believe that our future success depends largely on three factors:

• our ability to continue to support a number of popular operating systems and databases;

• our ability to maintain and improve our current product line; and

• our ability to rapidly develop new products that achieve market acceptance, maintain technological competitiveness and meet an expanding range of customer requirements.

Business intelligence applications are inherently complex, and it can take a long time and require significant research and development expenditures to develop and test new products and product enhancements. In addition, customers may delay their purchasing decisions because they anticipate that new or enhanced versions of our products will soon become available. We cannot be sure that we will succeed in developing and marketing, on a timely and cost-effective basis, product enhancements or new products that respond to technological change or new customer requirements, nor can we be sure that any new products and product enhancements will achieve market acceptance. Moreover, even if we introduce such a product, we may experience a decline in revenues of our existing products that is not fully matched by the new product’s revenue. In addition, we may lose existing customers who choose a competitor’s product rather than migrate to our new product. This could result in a temporary or permanent revenue shortfall and materially affect our business.

The emergence of new industry standards may adversely affect the demand for our existing products

The emergence of new industry standards in related fields may adversely affect the demand for our existing products. This could happen, for example, if new web standards and technologies emerged that were incompatible with customer deployments of our products. MicroStrategy currently supports SQL and MDX standards in database access technology. If we are unable to adapt our products on a timely basis to new standards in database access technology, the ability of MicroStrategy’s products to access customer databases could be impaired. In addition, the emergence of new standards in the field of operating system support could adversely affect the demand for our existing products. MicroStrategy technology is currently compatible with nearly all major operating systems, including, among others, Windows Server, Sun Solaris, IBM AIX, HP’s HP-UX and Redhat Linux AS. If a different operating system were to gain widespread acceptance, we may not be able to achieve compatibility on a timely basis, resulting in an adverse effect on the demand for our products.

The nature of our products makes them particularly vulnerable to undetected errors, or bugs, which could cause problems with how the products perform and which could in turn reduce demand for our products, reduce our revenue and lead to product liability claims against us

Software products as complex as ours may contain errors and/or defects. Although we test our products extensively, we have in the past discovered software errors in our products after their introduction. Despite testing by us and by our current and potential customers, errors may be found in new products or releases after commercial shipments begin. This could result in lost revenue, damage to our reputation or delays in market acceptance, which could have a material adverse effect upon our business, operating results and financial condition. We may also have to expend resources and capital to correct these defects.

Our license agreements with customers typically contain provisions designed to limit our exposure to product liability, warranty and other claims. It is possible, however, that these provisions may not be effective under the laws of certain domestic or international jurisdictions and we may be exposed to product liability, warranty and other claims. A successful product liability claim against us could have a material adverse effect on our business, operating results and financial condition.

Our intellectual property rights are valuable, and any inability to protect them could reduce the value of our products, services and brand

We rely on a combination of copyright, patent, trade secrets, confidentiality procedures and contractual commitments to protect our proprietary information. Despite our efforts, these measures can only provide limited

24

protection. Unauthorized third parties may try to copy or reverse engineer portions of our products or otherwise obtain and use our intellectual property. Any patents owned by 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. In addition, the laws of some countries do not provide the same level of protection of our proprietary rights as do the laws of the United States. If we cannot protect our proprietary technology against unauthorized copying or use, we may not remain competitive.

Third parties may claim we infringe their intellectual property rights

We periodically receive notices from others claiming we are infringing their intellectual property rights, principally patent rights. We expect the number of such claims will increase as the number of products and competitors in our industry segments grows, the functionality of products overlap, and the volume of issued software patents and patent applications continues to increase. Responding to any infringement claim, regardless of its validity, could:

• be time-consuming, costly and/or result in litigation;

• divert management’s time and attention from developing our business;

• require us to pay monetary damages or enter into royalty and licensing agreements that we would not normally find acceptable;

• require us to stop selling or to redesign certain of our products; or

• require us to satisfy indemnification obligations to our customers.

If a successful claim is made against us and we fail to develop or license a substitute technology, our business, results of operations, financial condition or cash flows could be adversely affected.

On October 2, 2001, we filed a lawsuit in the Virginia Circuit Court for Fairfax County against two field employees of Business Objects, S.A. This lawsuit alleged that these employees, who previously worked for us, breached their fiduciary and contractual obligations to us by, among other things, misappropriating our trade secrets and confidential information and soliciting our employees and customers. The complaint sought injunctive relief and monetary damages. On October 17, 2001, Business Objects filed suit against us in the United States District Court for the Northern District of California, claiming that our software infringes a patent issued to Business Objects relating to relational database access (the ‘403 patent). The suit sought injunctive relief and monetary damages. On August 29, 2003, the Court granted our motion for summary judgment and dismissed the lawsuit, ruling as a matter of law that our products do not infringe the ‘403 patent. Business Objects filed an appeal to the United States Court of Appeals for the Federal Circuit. On January 6, 2005, the Federal Circuit ruled that the district court had correctly construed the patent, that we do not literally infringe any of the asserted patent claims, and that Business Objects is legally barred from claiming that our products infringe two of the three asserted claims under the doctrine of equivalents. As a result of the Federal Circuit’s ruling, the case was remanded to the district court for further proceedings limited solely to Business Objects’ one remaining patent claim, and limited solely to the doctrine of equivalents. The Federal Circuit also reinstated all of our non-infringement and invalidity counterclaims brought against Business Objects that the district court had not needed to address or decide. On July 26, 2005, the district court granted our motion for summary judgment of non-infringement and dismissed the lawsuit. On August 19, 2005, Business Objects filed an appeal to the United States Court of Appeals for the Federal Circuit. That appeal remains pending and is being briefed by the parties.

On October 31, 2001, we filed suit against Business Objects, S.A. and its subsidiary, Business Objects Americas, Inc., in the United States District Court for the Eastern District of Virginia, claiming that Business Objects’ software infringes two patents held by us relating to asynchronous control of report generation using a web browser (the ‘033 patent) and a system and method of adapting automatic output of OLAP reports to disparate user output devices (the ‘050 patent). The complaint sought monetary damages and injunctive relief. On March 13, 2002, we voluntarily dismissed without prejudice our lawsuit pending in the Virginia Circuit Court

25

for Fairfax County against the two field employees of Business Objects. The complaint against Business Objects was amended to add claims for violations of the federal Computer Fraud and Abuse Act, misappropriation of trade secrets, tortious interference with contractual relations and violations of the Virginia Conspiracy Act. As a result of pre-trial rulings, certain of these claims were dismissed. Our claims for tortious interference and misappropriation of trade secrets proceeded to trial on October 20, 2003. On October 28, 2003, the Court dismissed the tortious interference claim. In July 2003, the United States Patent & Trademark Office confirmed the validity of all the claims in the ‘033 and ‘050 patents and terminated reexamination proceedings that Business Objects had requested as to those patents. We agreed to dismissal of the ‘033 patent claims without prejudice. On August 6, 2004, the Court granted Business Objects’ motion for summary judgment on the ‘050 patent claims, ruling that Business Objects had not infringed our patent. The Court ruled in our favor on our claims of trade secret misappropriation, finding that Business Objects had misappropriated certain of our trade secrets. On September 7, 2004, we filed a notice of appeal to the United States Court of Appeals for the Federal Circuit. Business Objects did not file a cross appeal. On November 17, 2005, the Federal Circuit reversed the District Court on our tortious interference claim and remanded that claim for further proceedings. The Federal Circuit affirmed the District Court on all other issues. On December 1, 2005, we filed a Combined Petition for Panel Rehearing and Rehearing En Banc. The Federal Circuit denied the Combined Petition on January 25, 2006.

On December 10, 2003, we filed a complaint for patent infringement against Crystal Decisions, Inc. in the United States District Court for the District of Delaware. The lawsuit alleged that Crystal Decisions willfully infringed three patents issued to us relating to: (i) asynchronous control of report generation using a web browser (the ‘033 patent); (ii) management of an automatic OLAP report broadcast system (the ‘796 patent); and (iii) providing business intelligence web content with reduced client-side processing (the ‘432 patent). We sought monetary damages and injunctive relief. Following the filing of the complaint, Crystal Decisions was acquired by Business Objects Americas, Inc. Business Objects Americas, Inc. answered the complaint, denying infringement and seeking a declaration that the patents in suit are invalid and not infringed by Business Objects Americas, Inc. We filed a motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents on October 13, 2005. Business Objects filed motions for summary judgment of non-infringement and invalidity of the ‘432, ‘796, and ‘033 patents on October 13, 2005. On January 23, 2006, the Court denied our motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents. The Court granted Business Objects’ motions for summary judgment of non-infringement of the ‘033 patent and of invalidity of the ‘432 and ‘796 patents. The Court denied Business Objects’ motion for summary judgment of invalidity of the ‘033 patent and denied as moot Business Objects’ motion for summary judgment of non-infringement of the ‘432 and ‘796 patents. On February 7, 2006, the Court dismissed without prejudice Business Objects’ counterclaim for declaratory judgment of invalidity of the ‘033 patent. On February 23, 2006, the Court entered judgment in favor of Business Objects and against MicroStrategy. Any notice of appeal to be filed by MicroStrategy is due by March 27, 2006.

The outcome of this litigation is not presently determinable.

Because of the rights of our two classes of common stock, and because we are controlled by our existing holders of class B common stock, these stockholders could transfer control of MicroStrategy to a third party without the approval of our Board of Directors or our other stockholders, prevent a third party from acquiring MicroStrategy, or limit your ability to influence corporate matters

We have two classes of common stock: class A common stock and class B common stock. Holders of our class A common stock generally have the same rights as holders of our class B common stock, except that holders of class A common stock have one vote per share while holders of class B common stock have ten votes per share. As of March 1, 2006, holders of our class B common stock owned 3,240,475 shares of class B common stock, or 76.4% of the total voting power. Michael J. Saylor, our Chairman, President and Chief Executive Officer, beneficially owned 235,800 shares of class A common stock and 2,789,430 shares of class B common stock, or 66.3% of the total voting power, as of March 1, 2006. Accordingly, Mr. Saylor is able to control MicroStrategy through his ability to determine the outcome of elections of our directors, amend our certificate of incorporation and by-laws and take other actions requiring the vote or consent of stockholders, including mergers, going-private transactions and other extraordinary transactions and their terms.

26

Our certificate of incorporation allows holders of class B common stock, almost all of whom are current employees or former employees of our company or related parties, to transfer shares of class B common stock, subject to the approval of stockholders possessing a majority of the outstanding class B common stock. Mr. Saylor or a group of stockholders possessing a majority of the outstanding class B common stock could, without the approval of our Board of Directors or our other stockholders, transfer voting control of MicroStrategy to a third party. Such a transfer of control could have a material adverse effect on our business, operating results and financial condition. Mr. Saylor or a group of stockholders possessing a majority of the outstanding class B common stock will also be able to prevent a change of control of MicroStrategy, regardless of whether holders of class A common stock might otherwise receive a premium for their shares over the then current market price. In addition, this concentrated control limits your ability to influence corporate matters and, as a result, we may take actions that our non-controlling stockholders do not view as beneficial. As a result, the market price of our class A common stock could be adversely affected.

Our principal offices are located in Northern Virginia and consist of approximately 260,000 square feet of leased facilities, including 77,000 square feet that has been subleased. The term of the lease expires in 2010 but may be extended at our option for two additional five-year terms.

In addition, we lease approximately 25,000 square feet of sales and administrative offices domestically and approximately 72,000 square feet of sales and administrative offices internationally in a variety of locations.

ITEM 3. LEGAL PROCEEDINGS

Business Objects Litigation

On October 2, 2001, we filed a lawsuit in the Virginia Circuit Court for Fairfax County against two field employees of Business Objects, S.A. This lawsuit alleged that these employees, who previously worked for us, breached their fiduciary and contractual obligations to us by, among other things, misappropriating our trade secrets and confidential information and soliciting our employees and customers.

On December 10, 2003, we filed a complaint for patent infringement against Crystal Decisions, Inc. in the United States District Court for the District of Delaware. The lawsuit alleged that Crystal Decisions willfully infringed three patents issued to us relating to: (i) asynchronous control of report generation using a web browser (the ‘033 patent); (ii) management of an automatic OLAP report broadcast system (the ‘796 patent); and (iii) providing business intelligence web content with reduced client-side processing (the ‘432 patent).

Business Objects Americas, Inc. answered the complaint, denying infringement and seeking a declaration that the patents in suit are invalid and not infringed by Business Objects Americas, Inc. We filed a motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents on October 13, 2005. Business Objects filed motions for summary judgment of non-infringement and invalidity of the ‘432, ‘796, and ‘033 patents on October 13, 2005. On January 23, 2006, the Court denied our motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents. The Court granted Business Objects’ motions for summary judgment of non-infringement of the ‘033 patent and of invalidity of the ‘432 and ‘796 patents. The Court denied Business Objects’ motion for summary judgment of invalidity of the ‘033 patent and denied as moot Business Objects’ motion for summary judgment of non-infringement of the ‘432 and ‘796 patents. On February 7, 2006, the Court dismissed without prejudice Business Objects’ counterclaim for declaratory judgment of invalidity of the ‘033 patent. On February 23, 2006, the Court entered judgment in favor of Business Objects and against MicroStrategy. Any notice of appeal to be filed by MicroStrategy is due by March 27, 2006.

The outcome of this litigation is not presently determinable.

Other Proceedings

We are also involved in other legal proceedings through the normal course of business. Management believes that any unfavorable outcome related to these other proceedings will not have a material effect on our financial position, results of operations or cash flows.

With extranet deployments, enterprises can use the MicroStrategy software platform to build stronger relationships by linking customers and suppliers via the Internet. We also offer a comprehensive set of consulting, education, technical support and technical advisory services for our customers and strategic partners.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.

The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates, particularly estimates relating to revenue recognition, valuation of net deferred tax assets, litigation and contingencies, have a material impact on our financial statements and are discussed in detail throughout our analysis of the results of operations discussed below.

In addition to evaluating estimates relating to the items discussed above, we also consider other estimates, including, but not limited to, those related to allowance for doubtful accounts, software development costs, intangible assets and provision for income taxes. We base our estimates on historical experience and various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.

32

MicroStrategy does not have any material ownership interest in any special purpose or other entities that are not wholly-owned and/or consolidated into our consolidated financial statements. Additionally, MicroStrategy does not have any material related party transactions as defined under Statement of Financial Accounting Standards (“SFAS”) No. 57, “Related Party Disclosures.”

We apply the following critical accounting policies in the preparation of our consolidated financial statements:

Revenue Recognition.    MicroStrategy’s software revenue recognition policies are in accordance with the American Institute of Certified Public Accountants’ Statement of Position (“SOP”) 97-2, “Software Revenue Recognition,” as amended. In the case of software arrangements that require significant production, modification or customization of software, we follow the guidance in SOP 81-1, “Accounting for Performance of Construction-Type and Certain Production-Type Contracts.” We also follow the guidance provided by SEC Staff Accounting Bulletin (“SAB”) No. 101, “Revenue Recognition in Financial Statements,” and SAB No. 104, “Revenue Recognition”.

We recognize revenue from sales of software licenses to end users or resellers upon:

1) persuasive evidence of an arrangement, as provided by agreements, contracts, purchase orders, or other arrangements, generally executed by both parties (other than certain customer specific instances in which we have a customary business practice of accepting orders without signed agreements);

2) delivery of the software; and

3) determination that collection of a fixed or determinable fee is reasonably assured.

When the fees for software upgrades and enhancements, technical support, consulting and education are bundled with the license fee, they are unbundled for revenue recognition purposes using our objective evidence of the fair value of the elements represented by our customary pricing for each element when sold separately. If such evidence of fair value exists for all undelivered elements and there is no such evidence of fair value established for delivered elements, the arrangement fee is first allocated to the elements where evidence of fair value has been established and the residual amount is allocated to the delivered elements. If evidence of fair value for any undelivered element of an arrangement does not exist, all revenue from the arrangement is deferred until such time that evidence of fair value exists for undelivered elements or until all elements of the arrangement are delivered, subject to certain limited exceptions set forth in SOP 97-2.

When a software license arrangement requires us to provide significant production, customization or modification of the software, or when the customer considers these services essential to the functionality of the software product, both the product licenses revenue and consulting services revenue are recognized using the percentage of completion method. Under percentage of completion accounting, both product licenses and consulting services revenue are recognized as work progresses based upon labor hours incurred. Any expected losses on contracts in progress are expensed in the period in which the losses become probable and reasonably estimable. Contracts accounted for under the percentage of completion method were not material for the years ended December 31, 2005, 2004 and 2003.

If an arrangement includes acceptance criteria, revenue is not recognized until we can objectively demonstrate that the software or service can meet the acceptance criteria or the acceptance period lapses, whichever occurs earlier. If a software license arrangement obligates us to deliver specified future products or upgrades, revenue is recognized when the specified future product or upgrades are delivered or when the obligation to deliver specified future products expires, whichever occurs earlier. If a software license arrangement obligates us to deliver unspecified future products, then revenue is recognized on the subscription basis, ratably over the term of the contract.

License revenue derived from sales to resellers or OEMs who purchase our products for resale is recognized upon sufficient evidence that the products have been sold to the ultimate end users provided all other revenue recognition criteria have been met.

33

Product support revenue is derived from providing technical software support and software updates and upgrades to customers. Product support revenue is recognized ratably over the term of the contract, which in most cases is one year.

Revenue from consulting, education and other services is recognized as the services are performed.

Amounts collected prior to satisfying the above revenue recognition criteria are included in deferred revenue and advance payments in the accompanying consolidated balance sheets.

The application of SOP 97-2, as amended, requires judgment, including a determination that collectibility is reasonably assured, the fee is fixed and determinable, whether a software arrangement includes multiple elements, and if so, whether vendor-specific objective evidence of fair value exists for those elements. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.

Litigation and Contingencies.    We are subject to various loss contingencies arising in the ordinary course of business. We consider the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted.

We are involved in lawsuits with Business Objects, S.A. and Business Objects Americas, Inc. relating to claims involving patent infringement and other intellectual property matters. The outcome of this litigation is not presently determinable, and as such, we are currently unable to estimate the potential range of gain or loss, if any, relating to these actions. Accordingly, no provision for these matters has been made in the accompanying consolidated financial statements. Additional information regarding these matters is included under “Item 1A. Risk Factors.”

We are also involved in other legal proceedings through the normal course of business. Management believes that any unfavorable outcome related to these other proceedings will not have a material effect on our financial position, results of operations or cash flows.

Income Taxes.    In determining our net deferred tax assets and valuation allowances, management is required to make judgments and estimates related to projections of domestic and foreign profitability, the timing and extent of the utilization of net operating loss carryforwards, applicable tax rates, transfer pricing methodologies and prudent and feasible tax planning strategies. Judgments and estimates related to our projections and assumptions are inherently uncertain; therefore, actual results could differ materially from our projections.

As a global company with subsidiaries in many countries, we are required to calculate and provide for estimated income tax liabilities for each of the tax jurisdictions in which we operate. This process involves estimating current tax obligations and exposures in each jurisdiction as well as making judgments regarding the future recoverability of deferred tax assets. Changes in the estimated level of annual pre-tax income, changes in tax laws particularly related to the utilization of net operating losses in various jurisdictions, and changes resulting from tax audits can all affect the overall effective income tax rate which, in turn, impacts the overall level of income tax expense and net income. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We consider future taxable income and ongoing tax planning strategies in assessing the need for a valuation allowance. Should we determine that we would not be able to realize all or part of net deferred tax assets in the future, an adjustment to deferred tax assets would reduce income in the period such determination was made.

Results of Operations

Comparison of the years ended 2005, 2004 and 2003

Revenues

Product licenses revenues.    The following table sets forth product licenses revenues (in thousands) and percentage changes for the periods indicated:

	Years Ended December 31,						% Change in 2005		% Change in 2004
	2005		2004		2003
Product Licenses Revenues:
Domestic (consists of the U.S. and Canada)	$	61,768	$	53,848	$	53,005	14.7	%	1.6	%

	Years Ended December 31,
	2005	2004	2003
Product License Transactions with Revenue Recognized in the Applicable Period:
Greater than $1.0 million of revenue recognized	10	8	6
Between $500,000 and $1.0 million of revenue recognized	24	22	20
Total transactions with greater than $500,000 of revenue recognized	34	30	26
Domestic:
Greater than $1.0 million of revenue recognized	8	4	5
Between $500,000 and $1.0 million of revenue recognized	18	16	18
Total domestic transactions with greater than $500,000 of revenue recognized	26	20	23

Between $500,000 and $1.0 million of revenue recognized	6	6	2
Total international transactions with greater than $500,000 of revenue recognized	8	10	3

Product licenses revenues increased in each of 2005 and 2004, as compared to the prior year, due to increases in the total number of recognized product license transactions and high-dollar product license transactions in both years. These increases were partially attributable to new product launches during those years.

Domestic product licenses revenues.    Domestic product licenses revenues increased in 2005, as compared to 2004, due to increases in the total number of recognized product license transactions and high-dollar product license transactions in 2005. The increase was partially attributable to new product launches during 2005.

Domestic product licenses revenues in 2004 were consistent with the prior year due to increases in the total number of recognized product license transactions, offset by a decrease in the number of high-dollar product license transactions.

International product licenses revenues.    International product licenses revenues decreased in 2005, as compared to 2004, due to a decrease in the number of high-dollar transactions in 2005. During 2005, we recognized revenue from two transactions, each in excess of $1.0 million, that together comprised $3.1 million of international product licenses revenues. During 2004, we recognized revenue from four transactions, each in excess of $1.0 million, that together comprised an aggregate of $12.4 million of international product licenses revenues. This decrease in high-dollar transactions was partially offset by increases in the total number of recognized international product license transactions in 2005.

35

International product licenses revenues increased in 2004, as compared to 2003, due to increases in high-dollar international product license transactions. During 2004, we recognized revenue from four transactions, each in excess of $1.0 million, that together comprised an aggregate of $12.4 million of international product licenses revenues. During 2003, we recognized revenue from one transaction in excess of $1.0 million that accounted for $1.3 million of international product licenses revenues.

International product licenses revenues were affected by favorable foreign currency fluctuations of 0.7%, 16.0%, and 12.6% in 2005, 2004, and 2003, respectively.

Product support revenues.    The following table sets forth product support revenues (in thousands) and percentage changes for the periods indicated:

	Years Ended December 31,						% Change in 2005		% Change in 2004
	2005		2004		2003
Product Support Revenues:
Domestic (consists of the U.S. and Canada)	$	70,021	$	55,861	$	42,130	25.3	%	32.6	%
International		45,830		35,209		22,243	30.2	%	58.3	%
Total revenues	$	115,851	$	91,070	$	64,373	27.2	%	41.5	%

Product support revenues are derived from providing technical software support and software updates and upgrades to customers. Product support revenues are recognized ratably over the term of the contract, which in most cases is one year.

Both domestic and international product support revenues increased in each of 2005 and 2004, as compared to the prior year, due to an increase in the average rate charged for product support services, an ongoing increase in our installed base of software licenses customers (customers generally purchase product support services at the time of product licenses purchases) and high renewal rates for such contracts.

International product support revenues were affected by favorable foreign currency fluctuations of 1.3%, 14.0% and 15.8% in 2005, 2004 and 2003, respectively.

Other Services.    The following table sets forth other services revenues (in thousands) and percentage changes for the periods indicated:

	Years Ended December 31,						% Change in 2005		% Change in 2004
	2005		2004		2003
Other Services Revenues:	$	52,885	$	43,143	$	33,983	22.6	%	27.0	%

Other services revenues includes consulting to help customers plan and execute the deployment of our software. Other services revenues also includes education and training, which we provide to our customers to enhance their ability to fully utilize the features and functionality of our software.

Consulting revenues increased in each of 2005 and 2004, as compared to the prior year, due to increases in the number of billable hours provided to our customers and an increase in average rates charged.

Education revenues increased in each of 2005 and 2004, as compared to the prior year, due to increases in the number of our training courses sold.

International other services revenues was affected by favorable foreign currency fluctuations of 1.7%, 10.1% and 12.2% in 2005, 2004 and 2003, respectively.

Costs and Expenses

Cost of Revenues.    The following table sets forth cost of revenues (in thousands) and percentage changes in cost of revenues for the periods indicated:

	Years Ended December 31,						% Change in 2005		% Change in 2004
	2005		2004		2003
Cost of Revenues:
Product licenses	$	3,886	$	3,875	$	3,240	0.3	%	19.6	%
Product support		8,225		7,708		6,590	6.7	%	17.0	%
Other services		24,340		21,288		18,155	14.3	%	17.3	%
Total cost of revenues	$	36,451	$	32,871	$	27,985	10.9	%	17.5	%

Cost of product licenses revenues.    Cost of product licenses revenues consists of amortization of capitalized software development costs and the costs of product manuals, media, and royalties paid to third-party software vendors. Capitalized software development costs are amortized over a useful life of three years.

Cost of product licenses revenues did not change significantly in 2005 as our most significant cost of product licenses revenues, capitalized software development amortization costs, were consistent with the prior year. In the first quarter of 2005, we began amortizing the costs related to the development of MicroStrategy 8. The amortization costs of MicroStrategy 8 were offset by the decrease in amortization costs related to MicroStrategy 7i and Narrowcast Server 7.2 which became fully amortized.

Cost of product support revenues.    Cost of product support revenues consists of product support personnel and related overhead costs.

The increase in cost of product support revenues in 2005, as compared to 2004, was primarily attributable to increases in product support personnel compensation costs.

The increase in cost of product support revenues in 2004, as compared to 2003, was primarily attributable to increases in product support staffing levels to ensure an adequate workforce to support our growing customer base.

Cost of product support revenues was affected by unfavorable foreign currency fluctuations of 0.2%, 2.4%, and 2.9% in the years 2005, 2004, and 2003, respectively.

Cost of other services revenues.    Cost of other services revenues consists of consulting and education personnel and related overhead costs.

The increases in cost of other services revenues in each of 2005 and 2004, as compared to the prior year, were primarily attributable to increases in both compensation costs and staffing levels in both years to ensure an adequate workforce to support our growing customer and revenue base.

Cost of other services revenues was affected by favorable foreign currency fluctuations of 0.2% in 2005 and was affected by unfavorable foreign currency fluctuations of 4.2% and 5.9% in 2004 and 2003, respectively.

37

Operating expenses.    The following table sets forth operating expenses (in thousands) and percentage changes in operating expenses for the periods indicated:

	Years Ended December 31,						% Change in 2005		% Change in 2004
	2005		2004		2003
Operating Expenses:
Sales and marketing	$	70,420	$	69,924	$	57,475	0.7	%	21.7	%
Research and development		31,471		24,915		27,684	26.3	%	-10.0	%
General and administrative		36,382		34,977		32,580	4.0	%	7.4	%
Other operating expenses		71		71		1,881	—		-96.2	%
Total operating expenses	$	138,344	$	129,887	$	119,620	6.5	%	8.6	%

Sales and marketing expenses.    Sales and marketing expenses consists of personnel costs, commissions, office facilities, travel, advertising, public relations programs and promotional events, such as trade shows, seminars and technical conferences.

Sales and marketing expenses in 2005 were consistent with the prior year, with an increase in staffing and compensation costs for our sales and marketing personnel offset by a decrease in discretionary marketing expenditures in 2005.

The increase in sales and marketing expenses in 2004, as compared to 2003, was primarily attributable to an increase in staffing and in compensation costs for our sales and marketing personnel.

Sales and marketing expenses was affected by unfavorable foreign currency fluctuations of 0.5%, 3.9% and 4.9% in 2005, 2004, and 2003, respectively.

Research and development expenses.    Research and development expenses consists of the personnel costs for our software engineering personnel, depreciation of equipment, and other related costs.

The following table summarizes research and development expenses and amortization of capitalized software development costs (in thousands) for the periods indicated:

	Years Ended December 31,
	2005			2004			2003
Gross research and development expenses:
Core research and development activities	$	30,440		$	27,458		$	26,859
Non-core research and development activities		1,957			1,725			1,999
Capitalized software development costs		(926	)		(4,268	)		(1,174	)
Total research and development expenses	$	31,471		$	24,915		$	27,684
Amortization of capitalized software development costs included in cost of product licenses revenues	$	2,736		$	2,483		$	1,895

The increase in research and development expenses in 2005, as compared to 2004, was primarily attributable to an increase in staffing levels and compensation costs of our research and development personnel and a decrease in capitalized software development costs.

The decrease in research and development expenses in 2004, as compared to 2003, was primarily attributable to an increase in capitalized software development costs, partially offset by an increase in compensation costs of our research and development personnel.

As of December 31, 2005, our research and development resources were allocated to the following projects: 48% to MicroStrategy 8, 34% to new product initiatives, and 18% to other research and development, including our non-core businesses, Angel.com and Alarm.com.

38

General and administrative expenses.    General and administrative expenses includes personnel and other costs of our executive, finance, human resources, information systems and administrative departments as well as third-party consulting, legal and other professional fees.

The increase in general and administrative expenses in 2005, as compared to 2004, was primarily attributable to an increase in compensation costs and staffing levels of our general and administrative personnel, partially offset by decreases in external accounting and auditing fees.

The increase in general and administrative expenses in 2004, as compared to 2003, was primarily attributable to an increase in compensation costs and staffing levels of our general and administrative personnel. In addition, external accounting and auditing fees increased due to costs associated with Sarbanes-Oxley Act compliance, partially offset by a decrease in external legal fees.

General and administrative expenses was affected by unfavorable foreign currency fluctuations of 0.5%, 2.1% and 1.7% in 2005, 2004, and 2003, respectively.

Provision (Benefit) for Income Taxes.    During 2005 we recorded a provision for income taxes of $33.4 million, resulting in an effective tax rate of 34.1%. Of the $33.4 million provision, $26.2 million was related to deferred taxes and was primarily related to the non-cash use of domestic net operating loss carryforwards. In 2004, we recorded a benefit for income taxes of $99.0 million caused primarily by the 2004 release of a valuation allowance related to our net operating loss tax assets, as described below.

As of December 31, 2005, we had net operating loss carryforwards of $236.7 million and other temporary differences, carryforwards, and credits, which resulted in net deferred tax assets of $109.4 million. We have domestic net operating loss carryforwards of $219.5 million that begin to expire in 2020, and $17.2 million of foreign loss carryforwards that begin to expire in 2007. Also, as of December 31, 2005, we had a valuation allowance of $8.1 million relating to certain foreign net operating loss carryforwards and domestic capital loss carryforward tax assets that we expect will expire unused.

We currently do not have plans to indefinitely reinvest undistributed foreign earnings. Accordingly, we expect to accrue a deferred tax liability less any applicable foreign tax credits on undistributed foreign earnings at such time as we have cumulative undistributed foreign earnings and an excess of the financial reporting basis in foreign subsidiaries over the tax basis of such subsidiaries. Currently there is an excess of the tax basis over the financial reporting basis for which no deferred tax asset has been recorded.

On October 22, 2004, the American Jobs Creation Act of 2004 (“AJCA”) was signed into law. The AJCA included a temporary incentive (“Section 965”) for U.S. companies to repatriate accumulated foreign earnings by providing an elective 85% dividends received deduction for certain dividends from controlled foreign corporations. In the third quarter of 2005, we repatriated $27.2 million from our Bermuda subsidiary as a qualified Section 965 dividend. The dividend resulted in a cash tax of $1.1 million, after use of an alternative minimum tax credit of $0.5 million.

The AJCA also included a qualified manufacturing deduction that applies to domestic manufacturers, including software companies. The deduction, when fully phased in, will provide a deduction of up to 9% of qualified manufacturing income. The deduction cannot be claimed by companies in a net operating loss carryforward position; therefore, we did not claim a benefit related to the qualified manufacturing deduction. We have not quantified the impact of the qualified manufacturing deduction that we can use once the net operating loss carryforward has been fully used.

Pursuant to the provisions of the Internal Revenue Code (“IRC”), an “ownership change” involving 5% or greater shareholders occurred in May 2003. The IRC provides an annual limitation on the amount of net operating losses and tax credits that may be used in the event of an ownership change. The limitation is based on,

39

among other things, the value of the company as of the date of change multiplied by a Federal long-term tax exempt rate. We do not currently expect the limitations under the IRS ownership change rules to impact our ability to use our net operating loss carryforwards. Accordingly, we have not established a valuation allowance in 2005 related to this issue.

During 2004, we recognized a net benefit for income taxes of $99.0 million. This benefit included a $107.4 million release of valuation allowance on net operating loss carryforward and other deferred tax assets. This benefit was partially offset by income tax expense incurred in our foreign operations. Based upon our cumulative operating results and an assessment of our expected future results of operations, we determined that it was more likely than not that we would be able to realize a substantial portion of our net operating loss carryforward tax assets prior to their expiration. As a result, during 2004, we released $125.4 million of our deferred tax asset valuation allowance. Of the $125.4 million, $103.6 million of the valuation release was recorded as an income tax benefit in our statement of operations, and $21.8 million of the valuation release was attributable to stock option exercises, which was recorded as an increase in additional paid in capital on the balance sheet. The total valuation allowance release recorded as an income tax benefit in our consolidated statement of operations during the third and fourth quarters of 2004 was $107.4 million.

During 2003, we recorded an income tax benefit of $2.6 million. The income tax benefit in 2003 included a $5.2 million reduction of valuation allowances on net operating loss carryforwards and other deferred tax assets in certain foreign subsidiaries that continued to demonstrate profitability. This benefit was partially offset by income tax expense incurred in our foreign operations. Also during 2003, we recognized a deferred tax asset of $9.1 million primarily related to domestic tax losses and certain other items. However, we recorded a full valuation allowance on this benefit.

Deferred Revenue and Advance Payments.    Deferred revenue and advance payments represents product support and other services fees that are collected in advance and recognized over the contract service period and product licenses revenues relating to multiple element software arrangements that include future deliverables.

The following table summarizes deferred revenue and advance payments (in thousands), as of:

	December 31,
	2005			2004
Current:
Deferred product licenses revenue	$	2,990		$	5,863
Deferred product support revenue		72,645			63,819
Deferred other services revenue		11,780			13,170
		87,415			82,852
Less: billed and unpaid deferred revenue		(41,541	)		(39,178	)
	$	45,874		$	43,674
Non-current:
Deferred product licenses revenue	$	174		$	290
Deferred product support revenue		2,228			1,974
Deferred other services revenue		18			5
		2,420			2,269
Less: billed and unpaid deferred revenue		(866	)		(588	)
	$	1,554		$	1,681

We offset our accounts receivable and deferred revenue for any billed and unpaid items included in deferred revenue and advance payments.

40

The increase in deferred revenue and advance payments in 2005, as compared to 2004, was primarily attributable to an ongoing increase in product support contracts associated with new product licenses sales, an increase in the average rate charged for product support and our high renewal rates of such contracts during 2005.

Including billed and unpaid deferred revenue, we expect to recognize $87.4 million of deferred revenue and advance payments over the next 12 months; however, the timing and ultimate recognition of our deferred revenue and advance payments depend on our performance of various service obligations, and the amount of deferred revenue and advance payments at any date should not be considered indicative of revenues for any succeeding period.

During 2005 we entered into certain agreements that include future commitments by our customers to purchase products, product support or other services over multi-year periods. Revenue relating to such future commitments by our customers is not included in our deferred revenue balances as of December 31, 2005, 2004, and 2003.

We do not expect revenue from multi-year arrangements will constitute a substantial percentage of our total revenue in future periods. Revenue relating to such agreements will be recognized during the period in which all revenue recognition criteria are met. The timing and ultimate recognition of any revenue from such customer purchase commitments depend on our customers’ meeting their future purchase commitments and our meeting our associated performance obligations related to those purchase commitments.

Liquidity and Capital Resources

Our principal sources of liquidity are cash, cash equivalents, investments, and on-going collection of our accounts receivable. On December 31, 2005 and 2004, we had $96.1 million and $132.5 million, respectively, in cash, cash equivalents, and investments. Management believes that existing cash and cash anticipated to be generated by operations will be sufficient to meet working capital requirements and anticipated capital expenditures for at least the next twelve months. Based upon our cash position, we do not currently expect to borrow money to finance our operations. Our liquidity and capital resources and ability to generate revenues are subject to various business and economic risks discussed under “Item 1A. Risk Factors.”

On March 15, 2005, we entered into a security agreement with a bank under which we posted cash to secure existing letters of credit. These letters of credit are used as security deposits for office leases, including the office lease for our corporate headquarters. We may invest the cash collateral under the security agreement in certain permitted investments. As of December 31, 2005, we had $4.2 million in cash collateral posted under the security agreement, all invested in money market funds.

On July 28, 2005, we announced that our Board of Directors had authorized our repurchase of up to an aggregate of $300.0 million of our class A common stock from time to time on the open market, pursuant to the 2005 Share Repurchase Program. The timing and amount of any shares repurchased will be determined by our management based on its evaluation of market conditions and other factors. The 2005 Share Repurchase Program has a five-year term, but may be suspended or discontinued by us at any time. The 2005 Share Repurchase Program may be funded using our working capital, as well as proceeds from any credit facilities and other borrowing arrangements which we may enter into in the future. Through December 31, 2005, we repurchased an aggregate of 97,193 shares of our class A common stock at an average price of $71.25 and an aggregate cost of $6.9 million pursuant to the 2005 Share Repurchase Program.

On July 27, 2004, we announced that our Board of Directors had authorized our repurchase of up to $35.0 million of our class A common stock (the “2004 Share Repurchase Program”). On April 26, 2005, our Board of Directors modified the 2004 Share Repurchase Program to increase, from $35.0 million to $130.0 million, the aggregate amount of class A common stock that we were authorized to repurchase. During the second quarter of 2005, we repurchased under the 2004 Share Repurchase Program 2,509,952 shares of class A common stock at

41

an average price per share of $50.82, at an aggregate cost of $127.6 million. Including repurchase activity from all prior periods, we repurchased an aggregate of 2,577,752 shares of class A common stock at an average price per share of $50.39 and an aggregate cost of $129.9 million under the 2004 Share Repurchase Program. Since repurchases under the 2004 Share Repurchase Program reached the aggregate authorized limit, the 2004 Share Repurchase Program was completed in the second quarter of 2005.

During 2005, under both the 2005 and 2004 Share Repurchase Programs, we repurchased an aggregate of 2,607,145 shares of class A common stock at an aggregate cost of $134.5 million. During 2004, under the 2004 Share Repurchase Program, we repurchased an aggregate of 67,800 shares of class A common stock at an aggregate cost of $2.3 million.

Subsequent to December 31, 2005, and through March 1, 2006, we repurchased an aggregate of 635,526 shares of class A common stock at an average price per share of $92.52 and an aggregate cost of $58.8 million under the 2005 Share Repurchase Program.

All of the amounts above relating to average price per share and aggregate cost include broker commissions.

Contractual Obligations.    The following table sets forth our contractual obligations, generally associated with lease commitments, net of total future minimum rentals to be received under noncancellable sublease agreements (in thousands):

	Years Ended December 31,
	2006		2007		2008		2009		2010		Thereafter		Total
Contractual obligations	$	11,473	$	9,072	$	8,334	$	7,430	$	4,013	$	1,410	$	41,732

Net Cash Provided by Operating Activities.    The increase in net cash provided by operating activities in 2005, as compared to 2004, was primarily attributable to an improvement in operating results, our utilization of deferred tax assets, and increases in our deferred revenue balances.

The increase in net cash provided by operating activities in 2004, as compared to 2003, was primarily attributable to an improvement in operating results, an increase in our deferred revenue balances, and a decrease in cash used for payment of accounts payable, accrued expenses, and accrued compensation, partially offset by a decrease in cash as a result of the net increase in our accounts receivable and increases in prepaid expenses, deposits and other assets.

Net Cash Provided by (Used in) Investing Activities.    The increase in net cash provided by investing activities in 2005 was primarily attributable to proceeds from sales and maturities of investments of $180.3 million during 2005, as compared to none in 2004, and offset by an increase in purchases of investments of $105.1 million. The decrease in net cash provided by investing activities in 2004, as compared to 2003, was attributable to the purchases of short and long-term U.S. treasury securities, and increases in capital expenditures, capitalized software development costs and restricted cash during 2004.

Net Cash Used in (Provided by) Financing Activities.    The increase in net cash used in financing activities in 2005, as compared to 2004, was primarily attributable to our repurchases of class A common stock during 2005, offset by proceeds from the issuance of class A common stock from exercises of employee stock options and our employee stock purchase plan. The increase in net cash used in financing activities in 2004, as compared to 2003, was primarily attributable to an increase in proceeds from the sale of class A common stock under our employee stock purchase plan and the exercise of employee stock options, offset by our repurchase of shares of class A common stock during 2004.

Off-Balance Sheet Arrangements.    We did not enter into any off-balance sheet arrangements during the years ended 2005, 2004, and 2003. We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future impact on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Recent Accounting Standards

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123 (revised) (“SFAS No. 123R”), “Share-Based Payment.” SFAS No. 123R eliminates the intrinsic value method under

42

Accounting Principles Board Opinion No. 25 as an alternative method of accounting for stock-based awards. SFAS No. 123R also revises the fair value-based method of accounting for share-based payment liabilities, forfeitures and modifications of stock-based awards and clarifies the guidance of SFAS No. 123, “Accounting for Stock-based Compensation,” in several areas, including measuring fair value, classifying an award as equity or as a liability and attributing compensation cost to reporting periods. In addition, SFAS No. 123R amends SFAS No. 95, “Statement of Cash Flows,” to require that excess tax benefits be reported as a financing cash inflow rather than as a reduction of taxes paid, which is included within operating cash flows.

We adopted SFAS No. 123R effective January 1, 2006. We estimate that the adoption of SFAS No. 123R, using the modified prospective method, will result in incremental pre-tax expense of approximately $1.2 million in 2006 based on our current share-based compensation plans.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about our market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We are exposed to the impact of interest rate changes and foreign currency fluctuations.

Interest Rate Risk.    Our exposure to risk for changes in interest rates relates primarily to short-term and long-term investments. We generally invest our excess cash in short-term, highly-rated, fixed rate financial instruments. These fixed rate investments are subject to interest rate risk and may fall in value if interest rates increase.

As of December 31, 2005 we held auction rate securities that could expose us to interest rate risk. Although the Company purchases these securities to hold for a short period of time, typically less than 40 days, the underlying securities are long-term municipal and corporate bonds with maturities ranging from twenty to thirty years. The securities are repriced through the Dutch auction process, generally every 7, 28, 30 or 35 days.

A 10% change in interest rates would not have a material impact on our financial position, results of operations, and cash flows.

Foreign Currency Risk.    We face exposure to adverse movements in foreign currency exchange rates. Our international revenues and expenses are denominated in foreign currencies, principally the euro and the British pound sterling. The functional currency of each of our foreign subsidiaries is the local currency.

International sales accounted for 38.4%, 40.7% and 34.0% of our total revenues for the years ended December 31, 2005, 2004, and 2003. We anticipate that international revenues will continue to account for a significant portion of total revenues.

Based on our overall currency rate exposure in foreign jurisdictions, a 10% change in foreign exchange rates could have a material impact on our financial position, results of operations and cash flows. For instance, if average exchange rates in 2005 had changed unfavorably by 10%, our 2005 total revenues and net income could have decreased by approximately $9.4 million and $4.7 million, respectively.

We attempt to minimize our foreign currency risk by converting our excess foreign currency held in foreign jurisdictions to U.S. dollar denominated cash and investment accounts. To date, we have not hedged the risks associated with foreign exchange exposure. Although we may do so in the future, we cannot be sure that any hedging techniques will be successful or that our business, results of operations, financial condition and cash flows will not be materially adversely affected by exchange rate fluctuations.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2005. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2005, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Such internal control includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2005. In making this assessment, our management used the criteria set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment, our management has determined that, as of December 31, 2005, our internal control over financial reporting is effective based on those criteria.

Our management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2005 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their attestation report which appears in Item 15 below.

44

Changes in Internal Control Over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended December 31, 2005 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Identification of Audit Committee/Audit Committee Financial Expert

We have a separately-designated standing Audit Committee of the Board of Directors, which provides the opportunity for direct contact between our independent auditors and the Board of Directors. The Audit Committee is currently comprised of Messrs. Calkins, Fowler, LaRue and Patten and was established in accordance with section 3(a)(58)(A) of the Exchange Act. Our Board of Directors has designated Messrs. Fowler and LaRue as audit committee financial experts under Item 401(h) of Regulation S-K. Each member of the Audit Committee is “independent” as defined under applicable SEC and Nasdaq rules.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act, requires our directors, executive officers and holders of more than 10% of our class A common stock to file with the SEC initial reports of ownership of our class A common stock and other equity securities on a Form 3 and reports of changes in such ownership on a Form 4 or Form 5. Directors, executive officers and holders of 10% of our class A common stock are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. To our knowledge, based solely on a review of our records and representations made by our directors and executive officers regarding their filing obligations, all Section 16(a) filing requirements were satisfied with respect to the fiscal year ended December 31, 2005 (“Fiscal Year 2005”).

Director Compensation

Director Compensation Arrangements

Each Outside Director receives a fee of $8,000 for each quarterly meeting of the Board of Directors which the Outside Director attends in person. An Outside Director may be paid a quarterly board meeting fee for attending a quarterly board meeting via telephonic conference call if the Outside Director has good reason for the Outside Director’s failure to attend such meeting in person as determined by the Chairman of the Board, but such payment is limited to one occurrence in any given fiscal year. Each Outside Director who is a member of the Audit Committee also receives a fee of $4,000 for each quarterly meeting of such committee which the Outside Director attends in person. Each Outside Director may receive fees up to $12,000 in any fiscal quarter for additional services delegated by the Board of Directors to such Outside Director in the Outside Director’s capacity as a member of the Audit Committee, the Board of Directors or any other committees of the Board of Directors, provided that any such fee paid with respect to a particular service must be approved by the Board of Directors following the completion of such service by the Outside Director. Each Outside Director is reimbursed for all reasonable out-of-pocket expenses incurred by him or her in attending meetings of the Board of Directors and any committee thereof and otherwise in performing his or her duties as an Outside Director, subject to compliance with our standard documentation policies regarding reimbursement of business expenses.

to the extent a Corporate Development Program is not at such time being used exclusively by the Company for business purposes. Eligible personnel include members of the Board of Directors of the Company, executive officers of the Company, and other employees of the Company and its subsidiaries. Any such personal use may be deemed compensation to such persons.

Employment Agreements

Our employees, including our executive officers, are generally required to enter into confidentiality agreements prohibiting the employees from disclosing any of our confidential or proprietary information. In addition, the agreements generally provide that upon termination, an employee will not provide competitive products or services and will not solicit our customers and employees for a period of one year. At the time of commencement of employment, our employees also generally sign offer letters specifying certain basic terms and conditions of employment. Otherwise, our employees are generally not subject to written employment agreements.

In July 2002, each of Messrs. Klein and Sanchez were granted options to purchase 70,000 and 35,000 shares of class A common stock, respectively, under our 1999 Stock Option Plan (the “1999 Plan”). The option agreements for each of these grants provide for the acceleration of vesting in the event of a change in control of the Company such that, as of the effective date of the change in control, at least fifty percent of the original grant is fully vested and the remaining unvested portion will vest as to fifty percent of the remaining unvested shares on the last day of the third month after the effective date of the change in control and the remaining unvested shares will vest on the last day of the sixth month after the effective date of the change in control. In addition, these option agreements provide that if, following the change in control, such officer’s employment is terminated by MicroStrategy other than for cause or by such officer for good reason, the option will vest in full on the effective date of such termination.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of

MicroStrategy Incorporated:

We have audited management’s assessment, included in the accompanying management’s report on internal control over financial reporting appearing under Item 9A, that MicroStrategy Incorporated (“the Company”) maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by COSO. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet and the related consolidated statements of operations, stockholders’ equity, and cash flows as of and for the year ended December 31, 2005 of the Company and our report dated March 2, 2006 expressed an unqualified opinion on those financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of

MicroStrategy Incorporated:

We have audited the accompanying consolidated balance sheet of MicroStrategy Incorporated (“the Company”) as of December 31, 2005, and the related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company, as of December 31, 2005, and the results of operations and cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The Schedule II is presented for purposes of additional analysis and is not a required part of the basic financial statements. This schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

MicroStrategy Incorporated:

In our opinion, the consolidated balance sheet as of December 31, 2004 and the related consolidated statements of operations, stockholders’ equity and cash flows listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of MicroStrategy Incorporated and its subsidiaries at December 31, 2004, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule for each of the two years in the period ended December 31, 2004 listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

(2)    Summary of Significant Accounting Policies

(a)  Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

(b)  Use of Estimates

The preparation of the consolidated financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to revenue recognition, allowance for doubtful accounts, investments, software development costs, intangible assets, commissions, income taxes including the carrying value of deferred tax assets, and litigation and contingencies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.

(c)  Reclassification

Certain prior year amounts in the consolidated financial statements have been reclassified to conform to the current year presentation.

(d)  Cash and Cash Equivalents and Restricted Cash and Investments

Cash equivalents include money market instruments and commercial paper. The Company generally considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

65

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Restricted cash and investments consists of cash and investment balances restricted in use by contractual obligations with third parties.

On March 15, 2005, the Company entered into a security agreement with a bank under which the Company posted cash to secure existing letters of credit. These letters of credit are used as security deposits for office leases, including the office lease for the Company’s corporate headquarters. The Company may invest the cash collateral under the security agreement in certain permitted investments. As of December 31, 2005, the Company had $4.2 million in cash collateral posted under the security agreement, all invested in money market funds that are included in restricted cash and investments in the accompanying balance sheet as of December 31, 2005.

(e)  Investments

Investments are comprised of short and long-term securities. The classification of investments is determined at the time of purchase and is re-evaluated as needed at each balance sheet date.

Held-to-maturity marketable securities are reported at amortized cost. Available-for-sale marketable securities are reported at fair value. Unrealized holding gains and losses, net of applicable taxes, are reported in accumulated other comprehensive income in stockholders’ equity until realized. Trading marketable securities are reported at fair value. Unrealized holding gains and losses, net of applicable taxes, are reported in the income statement. Any purchase discount is amortized over the term of the securities and recorded as interest income.

In the event that the cost of an investment exceeds its fair value, management evaluates among other factors, the duration and extent to which the fair value is less than cost; the financial health of and business outlook for the investee, including industry and sector performance, changes in technology and operational and financing cash flow factors; and the Company’s intent and ability to hold the investment. If a decline in fair value is considered to be other than temporary, the cost basis of the individual security is written down to fair value and the amount of the write-down is included in results of operations. Interest income is recognized when earned. Realized gains and losses for marketable securities are derived using the specific identification method for determining the cost of the securities sold.

(f)  Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: three years for computer equipment and purchased software, five years for office equipment and capital automobile leases, and ten years for office furniture. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the term of the lease, whichever is shorter.

Expenditures for maintenance and repairs are charged to expense as incurred. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized and depreciated over the remaining useful lives of the asset. When assets are retired or sold, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the results of operations.

Eligible internally developed software costs incurred are capitalized subsequent to the completion of the preliminary project stage. Such costs include external direct material and service costs, employee payroll and payroll-related costs. After all substantial testing and deployment is completed and the software is ready for its intended use, internally developed software costs are amortized using the straight-line method over the estimated useful life of the software, generally up to three years.

66

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company reviews long-lived assets, including intangible assets, for impairment annually or whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down by the amount by which the carrying value of the asset exceeds the related fair value of the asset.

(g)  Software Development Costs

Software development costs are expensed as incurred until technological feasibility has been established, at which time such costs are capitalized until the product is available for general release to customers. Capitalized software development costs include direct labor costs and fringe benefit costs attributed to programmers, software engineers and quality control and field certifiers working on products after they reach technological feasibility but before they are generally available to customers for sale. Technological feasibility is considered to be achieved when a product design and working model of the software product have been completed. Capitalized software development costs are amortized over the estimated product life of three years, on a straight-line basis.

Capitalized software development costs, net of accumulated amortization, were $3.7 million and $5.5 million as of December 31, 2005 and 2004, respectively. Amortization expense related to software development costs was $2.7 million, $2.5 million and $1.9 million for the years ended December 31, 2005, 2004 and 2003, respectively, and is included in cost of product licenses revenues. During the years ended December 31, 2005 and 2004, the Company capitalized software development costs of $0.9 million and $4.3 million, respectively. The Company conducts an analysis of the net realizable value of capitalized software development costs on at least an annual basis and has determined that there is no indication of impairment of the capitalized software development costs as future sales are adequate to support amortization costs.

(h)  Loss Contingencies and Legal Costs

The Company accrues loss contingencies that are believed to be probable and can be reasonably estimated. As events evolve during the administration and litigation process and additional information becomes known, the Company reassesses its estimates related to loss contingencies. Legal costs are expensed in the period in which the costs are incurred.

(i)  Deferred Revenue and Advance Payments

Deferred revenue and advance payments related to product support and other services result from payments received prior to the performance of services for consulting, education and technical support. Deferred revenue and advance payments related to product licenses result primarily from multiple element arrangements that include future deliverables. Deferred revenue comprises deferred product licenses revenue or deferred product support and other services revenue based on the objective fair value of the multiple elements of the arrangement, except for software licenses for which we do not have an objective measure of fair value. The Company offsets its accounts receivable and deferred revenue for any billed and unpaid items included in deferred revenue and advance payments.

The Company also enters into certain agreements that include future commitments by customers to purchase product licenses, product support or other services over multi-year periods. Revenue relating to future commitments is not included in deferred revenue balances.

The Company does not expect that revenue from the multi-year arrangements will constitute a substantial percentage of its projected total revenue in future periods. Revenue relating to such agreements will be recognized during the period in which all revenue recognition criteria are met. The timing and ultimate

67

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

recognition of any revenue from such customer purchase commitments depend on the customers’ meeting their future purchase commitments and the Company’s ability to meet its associated performance obligations related to those purchase commitments.

(j)  Revenue Recognition

MicroStrategy’s software revenue recognition policies are in accordance with the American Institute of Certified Public Accountants’ Statement of Position (“SOP”) 97-2, “Software Revenue Recognition,” as amended. In the case of software arrangements that require significant production, modification or customization of software, the Company follows the guidance in SOP 81-1, “Accounting for Performance of Construction-Type and Certain Production-Type Contracts.” The Company also follows the guidance provided by SEC Staff Accounting Bulletin (“SAB”) No. 101, “Revenue Recognition in Financial Statements,” and SAB No. 104, “Revenue Recognition”.

The Company recognizes revenue from sales of software licenses to end users or resellers upon:

1) persuasive evidence of an arrangement, as provided by agreements, contracts, purchase orders, or other arrangements, generally executed by both parties (other than certain customer specific instances in which the Company has a customary business practice of accepting orders without signed agreements);

2) delivery of the software; and

3) determination that collection of a fixed or determinable fee is reasonably assured.

When the fees for software upgrades and enhancements, technical support, consulting and education are bundled with the license fee, they are unbundled for revenue recognition purposes, using the Company’s objective evidence of the fair value of the elements represented by the Company’s customary pricing for each element when sold separately. If such evidence of fair value exists for all undelivered elements and there is no such evidence of fair value established for delivered elements, the arrangement fee is first allocated to the elements where evidence of fair value has been established and the residual amount is allocated to the delivered elements. If evidence of fair value for any undelivered element of an arrangement does not exist, all revenue from the arrangement is deferred until such time that evidence of fair value exists for undelivered elements or until all elements of the arrangement are delivered, subject to certain limited exceptions set forth in SOP 97-2.

When a software license arrangement requires the Company to provide significant production, customization or modification of the software, or when the customer considers these services essential to the functionality of the software product, both the product license revenue and consulting services revenue are recognized using the percentage of completion method. Under percentage of completion accounting, both product licenses and consulting services revenue are recognized as work progresses based on labor hours incurred. Any expected losses on contracts in progress are expensed in the period in which the losses become probable and reasonably estimable. Contracts accounted for under the percentage of completion method were not significant for the years ended December 31, 2005, 2004 and 2003.

If an arrangement includes acceptance criteria, revenue is not recognized until the Company can objectively demonstrate that the software or service can meet the acceptance criteria, or the acceptance period lapses, whichever occurs earlier. If a software license arrangement obligates the Company to deliver specified future products or upgrades, revenue is recognized when the specified future product or upgrades are delivered, or when the obligation to deliver specified future products expires, whichever occurs earlier. If a software license arrangement obligates the Company to deliver unspecified future products, then revenue is recognized on the subscription basis, ratably over the term of the contract.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

License revenue derived from sales to resellers or original equipment manufacturers (“OEM”) who purchase the Company’s products for future resale is recognized upon sufficient evidence that the products have been sold to the ultimate end users provided all other revenue recognition criteria have been met.

Product support revenue is derived from providing technical software support and software updates and upgrades to customers. Product support revenue is recognized ratably over the term of the contract, which in most cases is one year.

Revenue from consulting, education and other services is recognized as the services are performed.

Amounts collected prior to satisfying the above revenue recognition criteria are included in deferred revenue and advance payments in the accompanying consolidated balance sheets.

The application of SOP 97-2, as amended, requires judgment, including a determination that collectibility is reasonably assured, the fee is fixed and determinable, whether a software arrangement includes multiple elements, and if so, whether vendor-specific objective evidence of fair value exists for those elements. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.

(k)  Advertising Costs

Advertising production costs are expensed the first time the advertisement takes place. Media placement costs are expensed in the month the advertising appears. Advertising costs were $799,000, $508,000, and $1.5 million for the years ended December 31, 2005, 2004, and 2003. As of December 31, 2005 and 2004, the Company had no prepaid advertising costs.

(l) Income Taxes

The Company is subject to federal, state, and local income taxes in many foreign countries and recognizes deferred taxes in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 109, “Accounting for Income Taxes” issued by the Financial Accounting Standards Board (“FASB”). Deferred income taxes are provided based upon enacted tax laws and rates applicable to the periods in which the taxes become payable.

The Company provides a valuation allowance to reduce deferred tax assets to their estimated realizable value.

(m)  Basic and Diluted Earnings Per Share

Basic earnings per share is determined by dividing the net income attributable to common stockholders (for continuing operations and discontinued operations, as applicable) by the weighted average number of common shares and participating securities outstanding during the period. Participating securities are included in the basic earnings per share calculation when dilutive. Diluted earnings per share is determined by dividing the net income attributable to common stockholders (for continuing operations and discontinued operations, as applicable) by the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares are included in the diluted earnings per share calculation when dilutive. Potential common shares consisting of common stock issuable upon exercise of outstanding employee stock options and warrants are computed using the treasury stock method. Potential common shares also consisted of common stock issuable upon the conversion of preferred stock.

(n)  Stock-Based Compensation

The Company has stock-based compensation plans under which directors, officers, and other eligible employees have received stock options awards. All stock options granted under the Company’s stock plans have an exercise price equal to the market value of the underlying common stock on the date of grant. Because the Company measured compensation expense prior to January 1, 2006 based upon the intrinsic value method, no stock-based employee compensation cost is reflected in net income. If compensation expense had been recorded based on the fair value of awards under the stock option and purchase plans as set forth in SFAS No. 123, the Company’s net income would have been adjusted to equal the pro forma amounts presented below (in thousands, except per share data):

	2005			2004			2003
Net income (loss), as reported	$	64,743		$	168,313		$	(3,903	)
Stock-based employee compensation expense included in net income, as reported, net of tax		—			112			—
Stock-based employee compensation expense under fair value based method, net of tax		(2,282	)		(8,700	)		(12,830	)
Pro forma net income (loss)	$	62,461		$	159,725		$	(16,733	)
Basic net income (loss) per share, as reported	$	4.38		$	10.48		$	(0.26	)
Diluted net income (loss) per share, as reported	$	4.19		$	9.83		$	(0.26	)
Basic net income (loss) per share, pro forma	$	4.23		$	9.95		$	(1.13	)
Diluted net income (loss) per share, pro forma	$	4.05		$	9.36		$	(1.13	)

The pro forma stock-based compensation expense for 2005 is shown net of tax using combined domestic federal and state tax rates of approximately 38% in 2005 and 2004. Prior to the fourth quarter of 2004, the Company’s net deferred tax assets were fully offset by a valuation allowance. As such, there is no tax effect on the pro forma stock-based compensation expense for the nine months ended September 30, 2004 and the year ended December 31, 2003.

Employee Stock Options.    The Company has made no stock option grants since the first quarter of 2004. The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions used for option grants issued during 2004 and 2003, respectively: average volatility factors of 55% and 85%, average risk-free interest rates of 3% for both periods, average expected life of five years for both periods and no dividend yields for both periods.

The weighted average fair value of grants made under MicroStrategy’s stock option plans during 2004 and 2003 were $28.64 and $15.65, respectively.

Employee Stock Purchase Plan.    The following assumptions were used for shares issued during 2005, 2004 and 2003, respectively, under MicroStrategy’s employee stock purchase plan: average volatility factors of 66%, 55% and 85%, average risk-free interest rates of 3% for all periods, average expected life of 6 months and no dividend yields. The 1998 Employee Stock Purchase Plan was discontinued in July 2005.

(o)  Foreign Currency Translation

The functional currency of the Company’s international operations is the local currency. Accordingly, all assets and liabilities of these subsidiaries are translated using exchange rates in effect at the end of the period and

70

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

revenue and costs are translated using weighted average exchange rates for the period. The related translation adjustments are reported in accumulated other comprehensive income in stockholders’ equity. Transaction gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included in the results of operations.

Transaction gains and losses arising from transactions denominated in foreign currencies resulted in a net gain of $1.2 million in 2005, a net loss of $0.5 million in 2004, and a net gain of $0.5 million in 2003, and are included in other income (loss) on the accompanying statements of operations.

(p)  Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, accounts receivable and investments. The Company places its cash equivalents with high credit-quality financial institutions and invests its excess cash primarily in money market instruments. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity. The Company sells products and services to various companies across several industries throughout the world in the ordinary course of business. The Company routinely assesses the financial strength of its customers and maintains allowances for anticipated losses. As of December 31, 2005 and 2004, no individual customer accounted for 10% or more of net accounts receivable.

(q)  Fair Value of Financial Instruments

The carrying amounts of the Company’s cash, cash equivalents, accounts receivable and accounts payable approximate fair value. The fair market value for marketable securities is based on quoted market prices.

(r)  Comprehensive Income

Comprehensive income includes foreign currency translation adjustments and unrealized gains and losses on short-term investments classified as available for sale securities, net of related tax effects, which have been excluded from net income and reflected in stockholders’ equity.

(s)  Recent Accounting Standards

In December 2004, the FASB issued SFAS No. 123 (revised) (“SFAS No. 123R”), “Share-Based Payment.” SFAS No. 123R eliminates the intrinsic value method under Accounting Principles Board Opinion No. 25 as an alternative method of accounting for stock-based awards. SFAS No. 123R also revises the fair value-based method of accounting for share-based payment liabilities, forfeitures and modifications of stock-based awards and clarifies the guidance of SFAS No. 123, “Accounting for Stock-based Compensation,” in several areas, including measuring fair value, classifying an award as equity or as a liability and attributing compensation cost to reporting periods. In addition, SFAS No. 123R amends SFAS No. 95, “Statement of Cash Flows,” to require that excess tax benefits be reported as a financing cash inflow rather than as a reduction of taxes paid, which is included within operating cash flows.

The Company adopted SFAS No. 123R effective January 1, 2006. The Company estimates the adoption of SFAS No. 123R, using the modified prospective method, will result in incremental pre-tax expense of approximately $1.2 million in 2006 based on the Company’s current share-based compensation plans.

The Company offsets its accounts receivable and deferred revenue for any billed and unpaid items included in deferred revenue and advance payments.

(4)    Investments

During 2004 and 2005, the Company invested in U.S. Treasury securities with varying maturities. The Company classified these investments as held-to-maturity and accounted for these investments at amortized cost. As of December 31, 2004, the carrying value of these investments approximated market value.

During 2005, the Company made the determination that it would sell these investments in U.S. Treasury securities to fund repurchases of class A common stock pursuant to the Company’s 2004 Share Repurchase Program. As the Company no longer intended to hold the securities until maturity, the securities, with an aggregate carrying value of $49.6 million, were reclassified to available-for-sale, amortization of the purchase discounts ceased, and the securities were recorded at fair value.

Subsequent to the reclassification of the securities, the Company sold all its investments in U.S. Treasury securities and used the proceeds to repurchase class A common stock. The Company recorded a net realized loss of $0.1 million on the sales of U.S. Treasury securities.

As of December 31, 2005, the Company invested $53.7 million in auction rate securities of varying maturities. The Company has determined that it may sell these securities prior to maturity, has classified them as available-for-sale and has recorded these investments at fair market value.

(5)    Property and Equipment

Property and equipment consist of the following, as of December 31, (in thousands):

	2005			2004
Computer equipment and purchased software	$	24,210		$	22,967

(7)    Litigation

(a)  Business Objects Litigation

On October 2, 2001, the Company filed a lawsuit in the Virginia Circuit Court for Fairfax County against two field employees of Business Objects, S.A. This lawsuit alleged that these employees, who previously worked for the Company, breached their fiduciary and contractual obligations to the Company by, among other things, misappropriating the Company’s trade secrets and confidential information and soliciting the Company’s employees and customers. The complaint sought injunctive relief and monetary damages. On October 17, 2001, Business Objects filed suit against the Company in the United States District Court for the Northern District of California, claiming that the Company’s software infringes a patent issued to Business Objects relating to relational database access (the ‘403 patent). The suit sought injunctive relief and monetary damages. On August 29, 2003, the Court granted the Company’s motion for summary judgment and dismissed the lawsuit, ruling as a matter of law that the Company’s products do not infringe the ‘403 patent. Business Objects filed an appeal to the United States Court of Appeals for the Federal Circuit. On January 6, 2005, the Federal Circuit ruled that the district court had correctly construed the patent, that the Company does not literally infringe any of the asserted patent claims, and that Business Objects is legally barred from claiming that the Company’s products infringe two of the three asserted claims under the doctrine of equivalents. As a result of the Federal Circuit’s ruling, the case was remanded to the district court for further proceedings limited solely to Business Objects’ one remaining patent claim, and limited solely to the doctrine of equivalents. The Federal Circuit also reinstated all of the Company’s non-infringement and invalidity counterclaims brought against Business Objects that the district court had not needed to address or decide. On July 26, 2005, the district court granted the Company’s motion for summary judgment of non-infringement and dismissed the lawsuit. On August 19, 2005, Business Objects filed an appeal to the United States Court of Appeals for the Federal Circuit. That appeal remains pending and is being briefed by the parties.

On October 31, 2001, the Company filed suit against Business Objects, S.A. and its subsidiary, Business Objects Americas, Inc., in the United States District Court for the Eastern District of Virginia, claiming that Business Objects’ software infringes two patents held by the Company relating to asynchronous control of report generation using a web browser (the ‘033 patent) and a system and method of adapting automatic output of OLAP reports to disparate user output devices (the ‘050 patent). The complaint sought monetary damages and injunctive relief. On March 13, 2002, the Company voluntarily dismissed without prejudice the Company’s lawsuit pending in the Virginia Circuit Court for Fairfax County against the two field employees of Business Objects. The complaint against Business Objects was amended to add claims for violations of the federal Computer Fraud and Abuse Act, misappropriation of trade secrets, tortious interference with contractual relations and violations of the Virginia Conspiracy Act. As a result of pre-trial rulings, certain of these claims were dismissed. The Company’s claims for tortious interference and misappropriation of trade secrets proceeded to trial on October 20, 2003. On October 28, 2003, the Court dismissed the tortious interference claim. In July 2003, the United States Patent & Trademark Office confirmed the validity of all the claims in the ‘033 and ‘050 patents and terminated reexamination proceedings that Business Objects had requested as to those patents. The Company agreed to dismissal of the ‘033 patent claims without prejudice. On August 6, 2004, the Court granted Business Objects’ motion for summary judgment on the ‘050 patent claims, ruling that Business Objects had not infringed the Company’s patent. The Court ruled in the Company’s favor on its claims of trade secret misappropriation, finding that Business Objects had misappropriated certain of the Company’s trade secrets. On September 7, 2004, the Company filed a notice of appeal to the United States Court of Appeals for the Federal Circuit. Business Objects did not file a cross appeal. On November 17, 2005, the Federal Circuit reversed the District Court on the Company’s tortious interference claim and remanded that claim for further proceedings. The Federal Circuit affirmed the District Court on all other issues. On December 1, 2005, the Company filed a Combined Petition for Panel Rehearing and Rehearing En Banc. The Federal Circuit denied the Combined Petition on January 25, 2006.

On December 10, 2003, the Company filed a complaint for patent infringement against Crystal Decisions, Inc. in the United States District Court for the District of Delaware. The lawsuit alleged that Crystal Decisions willfully infringed three patents issued to the Company relating to: (i) asynchronous control of report generation using a web browser (the ‘033 patent); (ii) management of an automatic OLAP report broadcast system (the ‘796 patent); and (iii) providing business intelligence web content with reduced client-side processing (the ‘432 patent). The Company sought monetary damages and injunctive relief. Following the filing of the complaint, Crystal Decisions was acquired by Business Objects Americas, Inc. Business Objects Americas, Inc. answered the complaint, denying infringement and seeking a declaration that the patents in suit are invalid and not infringed by Business Objects Americas, Inc. The Company filed a motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents on October 13, 2005. Business Objects filed motions for summary judgment of non-infringement and invalidity of the ‘432, ‘796, and ‘033 patents on October 13, 2005. On January 23, 2006, the Court denied the Company’s motion for summary judgment of infringement of the ‘432, ‘796, and ‘033 patents. The Court granted Business Objects’ motions for summary judgment of non-infringement of the ‘033 patent and of invalidity of the ‘432 and ‘796 patents. The Court denied Business Objects’ motion for summary judgment of invalidity of the ‘033 patent and denied as moot Business Objects’ motion for summary judgment of non-infringement of the ‘432 and ‘796 patents. On February 7, 2006, the Court dismissed without prejudice Business Objects’ counterclaim for declaratory judgment of invalidity of the ‘033 patent. On February 23, 2006, the Court entered judgment in favor of Business Objects and against the Company. Any notice of appeal to be filed by the Company is due by March 27, 2006.

(b)  Other Matters

The Company is also involved in other legal proceedings through the normal course of business. Management believes that any unfavorable outcome related to these other proceedings will not have a material effect on the Company’s financial position, results of operations or cash flows.

(8)    Notes Payable

Pursuant to settlement agreements relating to the Company’s securities class action litigation, the Company issued $80.3 million of 7 ¹/2% series A unsecured notes (“Series A Notes”). The Series A Notes accrued interest at a rate of 7.5% per annum and were to mature on June 24, 2007. A discount of $25.3 million was to be amortized to interest expense over the term of such notes, using the effective interest method.

In 2003, the Company converted the then remaining $63.3 million of its Series A Notes into 1,972,649 shares of the Company’s class A common stock. In connection with conversion, the Company recorded a $31.1 million loss on the early extinguishment of notes payable equal to the excess of the fair value of the consideration transferred to the holders of the Series A Notes over the carrying value of the extinguished notes.

In connection with the refinancing of its series B, C and D preferred stock in August 2002, the Company issued to preferred stockholders, among other consideration, $5.0 million in promissory notes which accrued interest at a rate of 7.5% per annum, payable semi-annually, that matured on July 31, 2003. A discount of $0.5 million was amortized to interest expense over the term of such promissory notes, using the effective interest method. Upon maturity of the promissory notes on July 31, 2003, the Company paid $5.2 million to repay in full the principal and interest due under the promissory notes issued to former preferred stockholders. During the year ended December 31, 2003, the Company made total interest payments on the promissory notes of $0.4 million, including the interest payment made upon maturity.

(9)    Commitments and Contingencies

The Company leases office space and computer and other equipment under operating lease agreements. In addition to base rent, the Company is responsible for certain taxes, utilities and maintenance costs and several leases include options for renewal or purchase. Future minimum payments under noncancellable operating leases and agreements with initial terms of greater than one year consist of the following, net of total future minimum rentals to be received under noncancellable sublease agreements (in thousands):

The Company has research and development tax credit carryforward tax assets of $4.2 million, which begin to expire in 2019, foreign tax credit tax assets of $2.7 million which begin to expire in 2015, and $1.0 of alternative minimum tax (“AMT”) credit carryforward tax assets, which have no expiration. The timing and manner in which the Company will utilize the net operating loss carryforwards, research and development tax credit carryforward tax assets, and AMT tax credit carryforward tax assets in any year, or in total, may be limited by provisions of the Internal Revenue Code regarding changes in ownership of the Company (see discussion below).

The valuation allowance of $8.1 million at December 31, 2005 primarily relates to certain foreign net operating loss carryforwards and a domestic capital loss carryforward that the company expects will expire unused.

The Company does not currently have plans to indefinitely reinvest undistributed foreign earnings. Accordingly, the company expects to accrue a deferred tax liability less any applicable foreign tax credits on undistributed foreign earnings at such time as the company has cumulative undistributed foreign earnings and an excess of the financial reporting basis in foreign subsidiaries over the tax basis of such subsidiaries. Currently there is an excess of the tax basis over the financial reporting basis for which no deferred tax asset has been recorded.

On October 22, 2004, the American Jobs Creation Act of 2004 (“AJCA”) was signed into law. The AJCA included a temporary incentive (“Section 965”) for U.S. companies to repatriate accumulated foreign earnings by providing an elective 85% dividends received deduction for certain dividends from controlled foreign corporations. In the third quarter of 2005, the company repatriated $27.2 million from our Bermuda subsidiary as

77

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

a qualified Section 965 dividend. The dividend resulted in a cash tax of $1.1 million, after use of a prior year alternative minimum tax credit of $0.5 million.

The AJCA also included a qualified manufacturing deduction that applies to domestic manufacturers including software companies. The deduction, when fully phased in, will provide a deduction of up to 9% of qualified manufacturing income. The deduction cannot be claimed by companies in a net operating loss carryforward position; therefore, the company did not claim a 2005 benefit related to the qualified manufacturing deduction. The Company has not quantified the impact of the qualified manufacturing deduction that it can use once the net operating loss carryforward has been fully used.

Pursuant to the provisions of the Internal Revenue Code (“IRC”), an “ownership change” involving 5% or greater shareholders occurred in May 2003. The IRC provides an annual limitation on the amount of net operating losses and tax credits that may be used in the event of an ownership change. The limitation is based on, among other things, the value of the company as of the change date multiplied by a Federal long-term tax exempt rate. We do not currently expect the limitations under the IRS ownership change rules to impact our ability to use our net operating loss carryforwards. Accordingly, the Company has not established a valuation allowance in 2005 related to the company’s remaining Federal net operating loss carryforward deferred tax asset or other tax credit assets.

(b)  2004

As of June 30, 2004, the Company’s U.S. and Canadian net operating losses and other deferred tax assets were fully offset by a valuation allowance primarily because, at the time, the Company did not have sufficient history of taxable income to conclude that it was more likely than not that the Company would be able to realize the tax benefits of those deferred tax assets. Based upon the Company’s cumulative operating results and an assessment of the Company’s expected future results of operations, the Company determined that it was more likely than not that it would be able to realize a substantial portion of its U.S. and Canadian net operating loss carryforward tax assets prior to their expiration and other deferred tax assets. As a result, at September 30, 2004, the Company released a total of $125.4 million of its U.S. and Canadian deferred tax asset valuation allowance. Of the $125.4 million, $103.6 million of the valuation release was recorded as an income tax benefit in the Company’s statement of operations, and $21.8 million of the valuation release was attributable to stock option exercises, which was recorded as an increase in additional paid in capital on the balance sheet. As disclosed during the third quarter of 2004, an additional $3.8 million of the valuation allowance was released during the fourth quarter of 2004 as a result of the requirement under Accounting Principles Board No. 28 “Interim Financial Reporting” to use an annualized effective tax rate for each interim period during the year, including current year interim periods after a valuation allowance release has occurred. The total valuation allowance release recorded as an income tax benefit in the Company’s consolidated statement of operations during the third and fourth quarters of 2004 was $107.4 million.

The Company recorded a net $138.4 million decrease in the valuation allowance for the year ended December 31, 2004. The major components of the decrease in the valuation allowance are comprised of the following (in millions):

	2004
Valuation allowance release included in the provision (benefit) for income taxes:	$	107.4
Valuation allowance release included in additional paid-in capital:		21.8
Reduction in valuation allowance related to year-to-date operations prior to the valuation allowance release during the third quarter:		9.2
Total change in valuation allowance during 2004:	$	138.4

The remaining valuation allowance as of December 31, 2004 primarily relates to certain foreign net operating loss carryforwards and domestic capital loss carryforward that we expect will expire unused.

The Company does not currently have plans to indefinitely reinvest undistributed foreign earnings. Accordingly, we expect to accrue a deferred tax liability less any applicable foreign tax credits on undistributed foreign earnings at such time as we have cumulative undistributed foreign earnings and an excess of the financial reporting basis over the tax basis. Currently there is an excess of the tax basis over the financial reporting basis for which no deferred tax asset has been recorded.

(c)  2003

During the year ended December 31, 2003, the company recorded an income tax benefit of $2.6 million. The income tax benefit in 2003 included a $5.2 million reduction of valuation allowances on net operating loss carryforwards and other deferred tax assets in certain foreign subsidiaries that continued to demonstrate profitability. This benefit was partially offset by income tax expense incurred in our foreign operations. Also during 2003, the company recognized a deferred tax asset of $9.1 million primarily related to domestic tax losses and certain other items. However, because the realization of this deferred tax asset was not more likely than not, the company recorded a full valuation allowance on this benefit.

(11)    Basic and Diluted Earnings (Loss) per Share

The following table sets forth the computation of basic and diluted earnings (loss) per share for the years ended December 31, (in thousands, except per share data):

Employee stock options of 858,227 were excluded from the diluted loss per share calculation for the year ended December 31, 2003 because their effect would have been anti-dilutive.

(b)  Warrants

MICROSTRATEGY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

class A common stock at an exercise price of $400.00 per share, all of which were outstanding as of December 31, 2005. These warrants expire in June 2007.

(c)  Treasury Stock

On July 28, 2005, the Company announced that its Board of Directors had authorized the Company’s repurchase of up to an aggregate of $300.0 million of its class A common stock from time to time on the open market (the “2005 Share Repurchase Program”). The timing and amount of any shares repurchased will be determined by the Company’s management based on its evaluation of market conditions and other factors. The 2005 Share Repurchase Program has a five-year term, but may be suspended or discontinued by the Company at any time. The 2005 Share Repurchase Program may be funded using the Company’s working capital, as well as proceeds from any credit facilities and other borrowing arrangements which the Company may enter into in the future. Through December 31, 2005, the Company repurchased an aggregate of 97,193 shares of class A common stock at an average price per share of $71.25 and an aggregate cost of $6.9 million.

On July 27, 2004, the Company announced that its Board of Directors had authorized the Company’s repurchase of up to $35.0 million of its class A common stock (the “2004 Share Repurchase Program”). On April 26, 2005, the Company’s Board of Directors modified the 2004 Share Repurchase Program to increase, from $35.0 million to $130.0 million, the aggregate amount of class A common stock that the Company is authorized to repurchase. During the second quarter of 2005, the Company repurchased under the 2004 Share Repurchase Program 2,509,952 shares of class A common stock at an average price per share of $50.82, at an aggregate cost of $127.6 million. Including repurchase activity from all prior periods, the Company repurchased an aggregate of 2,577,752 shares of class A common stock at an average price per share of $50.39 and an aggregate cost of $129.9 million under the 2004 Share Repurchase Program. Since repurchases under the 2004 Share Repurchase Program reached the aggregate authorized limit, the 2004 Share Repurchase Program was completed in the second quarter of 2005.

During 2005, under both the 2005 and 2004 Share Repurchase Plans, the Company repurchased an aggregate of 2,607,145 shares of class A common stock at an aggregate cost of $134.5 million. During 2004, under the 2004 Share Repurchase Plan, the Company repurchased an aggregate of 67,800 shares of class A common stock at an aggregate cost of $2.3 million

Subsequent to December 31, 2005, and through March 1, 2006, the Company repurchased an aggregate of 635,526 shares of class A common stock at an average price per share of $92.52 and an aggregate cost of $58.8 million under the 2005 Share Repurchase Program.

All of the amounts above relating to average price per share and aggregate cost include broker commissions.

(13)    Employee Benefit Plan

The Company sponsors a benefit plan to provide retirement and incidental benefits for its employees, known as the MicroStrategy Incorporated 401(k) Savings Plan (the “Plan”). Participants may make voluntary contributions to the Plan of up to 20% of their annual base pre-tax compensation, cash bonuses and commissions not to exceed the federally determined maximum allowable contribution amounts. The Plan permits for discretionary company contributions; however, no such contributions were made during 2005, 2004, or 2003.

Cash Bonus Compensation

The Compensation Committee is authorized to develop, adopt and implement compensation arrangements, including cash bonus awards, for Mr. Saylor. The Compensation Committee established a formula (“2006 Bonus Formula”) for determining the bonus amount with respect to Mr. Saylor’s performance for the period from January 1, 2006 through December 31, 2006 based on a performance goal relating to the Company’s diluted earnings per share for the period from January 1, 2006 through December 31, 2006. The Compensation Committee has the right to use discretion to award a cash bonus amount lower than the amount calculated using the 2006 Bonus Formula.

The Chief Executive Officer is authorized to develop, adopt and implement compensation arrangements, including cash bonus awards, for Messrs. Bansal, Klein, Locke and Sanchez. The Chief Executive Officer has not yet determined the terms for any such cash bonus plan or award for 2006.

Other Compensation

The Compensation Committee may also, from time to time, award each of the named executive officers compensation in the form of stock options granted under the Company’s Second Amended and Restated 1999 Stock Option Plan.

On February 25, 2005, the Company entered into an agreement with Alcantara LLC, a Delaware limited liability company (“Alcantara”) of which Mr. Saylor is the sole member. Under the agreement, the Company is (i) providing to Alcantara use of approximately 150 square feet of office space within the Company’s leased space at 1861 International Drive, McLean, Virginia, (ii) providing to Alcantara various related services, and (iii) providing to Mr. Saylor gross-up payments in respect of taxes that he may incur as a result of the arrangement. The agreement does not require any rental or other payments from Alcantara or Mr. Saylor. The Company has filed a copy of this agreement as Exhibit 10.19 to the Annual Report on Form 10-K for the fiscal year ended December 31, 2004.

The Company also pays Mr. Saylor’s monthly dues at a private club that offers dining services and hosts business, professional and social community events.

In addition, the Company is authorized to make available, from time to time, tickets to sporting, charity, dining, entertainment or similar events as well as use of corporate suites, club memberships or similar facilities that the company may acquire (“Corporate Development Programs”), for personal use by Company personnel to the extent a Corporate Development Program is not at such time being used exclusively by the Company for business purposes. Eligible personnel include members of the Board of Directors of the Company, executive officers of the Company, and other employees of the Company and its subsidiaries. Any such personal use may be deemed compensation to such persons.

Exhibit 10.15

Summary of 2006 Compensation for Non-employee Directors

Each non-employee director (“Outside Director”) receives a fee of $8,000 for each quarterly meeting of the Board of Directors which the Outside Director attends in person. An Outside Director may be paid a quarterly board meeting fee for attending a quarterly board meeting via telephonic conference call if the Outside Director has good reason for the Outside Director’s failure to attend such meeting in person as determined by the Chairman of the Board, but such payment is limited to one occurrence in any given fiscal year. Each Outside Director who is a member of the Audit Committee also receives a fee of $4,000 for each quarterly meeting of such committee which the Outside Director attends in person. Each Outside Director may receive fees up to $12,000 in any fiscal quarter for additional services delegated by the Board of Directors to such Outside Director in the Outside Director’s capacity as a member of the Audit Committee, the Board of Directors or any other committees of the Board of Directors, provided that any such fee paid with respect to a particular service must be approved by the Board of Directors following the completion of such service by the Outside Director. Each Outside Director is reimbursed for all reasonable out-of-pocket expenses incurred by him or her in attending meetings of the Board of Directors and any committee thereof and otherwise in performing his or her duties as an Outside Director, subject to compliance with our standard documentation policies regarding reimbursement of business expenses.

In addition, the Company is authorized to make available, from time to time, tickets to sporting, charity, dining, entertainment or similar events as well as use of corporate suites, club memberships or similar facilities that the company may acquire (“Corporate Development Programs”), for personal use by Company personnel to the extent a Corporate Development Program is not at such time being used exclusively by the Company for business purposes. Eligible personnel include members of the Board of Directors of the Company, executive officers of the Company, and other employees of the Company and its subsidiaries. Any such personal use may be deemed compensation to such persons.

MICROSTRATEGY INCORPORATED

MATERIAL TERMS FOR PAYMENT OF

CERTAIN EXECUTIVE INCENTIVE COMPENSATION

Payment of incentive compensation to the Company’s chief executive officer and four other most highly compensated officers (the “covered executive officers”), as determined in accordance with the applicable rules under the Internal Revenue Code (the “Code”) and the Securities Exchange Act of 1934, may be made contingent upon the attainment of one or more performance goals (which may be stated as alternative goals) established in writing by the Compensation Committee of the Board of Directors for a covered executive officer for each performance period, which period may be for the Company’s taxable year or such other period as the Compensation Committee may determine. Performance goals will be based on one or more of the following business criteria, which may be measured on a GAAP (generally accepted accounting principles) or non-GAAP basis: (1) total stockholder return; (2) such total stockholder return as compared to total return (on a comparable basis) of a publicly available index such as, but not limited to, the Standard & Poor’s 500 Stock Index; (3) net income; (4) pretax earnings; (5) earnings before interest expense, taxes, depreciation and amortization; (6) pretax operating earnings after interest expense and before bonuses and extraordinary or special items; (7) operating margin; (8) earnings per share; (9) return on equity; (10) return on capital; (11) return on investment; (12) operating earnings; (13) working capital; (14) ratio of debt to stockholders’ equity; and (15) revenue.

Such performance-based compensation by the Company will be paid solely on account of the attainment of one or more objective performance goals established in writing by the Compensation Committee no later than 90 days after commencement of the performance period to which the goals relate (but in no event after 25% of the period has elapsed) and at a time when the attainment of such goals is substantially uncertain. Performance goals will be based on one or more of the foregoing business criteria that apply to an individual, a business unit or the Company as a whole, but need not be based on an increase or positive result under the business criteria selected. For compensation that qualifies as performance-based compensation, the Compensation Committee is prohibited from increasing the amount of compensation payable if a performance goal is met, but may reduce or eliminate compensation even if such performance goal is attained.

The maximum qualified performance-based compensation award that may be granted to any covered executive officer based on attainment of one or more of the foregoing performance goals for performance periods of one year or less is $8 million (with any amount paid for a performance period of less than one year counting against the limit for the fiscal year in which or with which such performance period ends). The maximum qualified performance-based compensation award that may be granted to any covered executive officer based on attainment of one or more of the foregoing performance goals for a performance period that is longer than one year is $40 million.

The Compensation Committee from time to time may approve payment of discretionary incentive compensation based on business criteria other than the foregoing performance goals. Any such discretionary compensation would not qualify for the exclusion from the $1 million limitation of deductible compensation under Section 162(m).

Adopted by the Board of Directors on June 30, 2005.

Approved by the stockholders on August 4, 2005.
