PROSPECTUS

                           MICROSTRATEGY INCORPORATED

                    1,900,000 Shares of Class A Common Stock

                                  -----------

  The shares of class A common stock described in this prospectus are issuable
upon exercise of warrants to be issued to class members pursuant to a
settlement agreement among us, some of our officers and directors and
plaintiffs' counsel, approved by the United States District Court for the
Eastern District of Virginia on April 2, 2001, relating to a consolidated class
action lawsuit filed against us, some of our officers and directors and our
independent accountants. We will sell the shares to the class members upon
exercise of the warrants at an exercise price of $40.00 per share. If all of
the warrants were exercised for cash, we would receive aggregate gross cash
proceeds of $76,000,000. However, holders of the warrants may not exercise some
or all of the warrants. In addition, the warrants may be exercised by the
surrender of notes issued by us to the class members pursuant to the settlement
agreement as payment of the exercise price, valued for this purpose at 133% of
the principal amount and all accrued and unpaid interest on the notes so
surrendered. Therefore, the amount of any cash proceeds that we may receive
upon exercise of the warrants is uncertain.

  We have filed a registration statement for the resale of 25,563,896 shares of
class A common stock by various selling stockholders, which were issued in
exchange for our series A preferred stock or are issuable upon conversion of or
as dividends on our series B preferred stock, series C preferred stock, series
D preferred stock and series E preferred stock. These 25,563,896 shares are not
offered by means of this prospectus. These shares may be sold by the selling
stockholders from time to time, including concurrently with the offering made
pursuant to this prospectus.

  Our class A common stock is traded on the Nasdaq National Market under the
symbol "MSTR." On October 15, 2001, the closing sale price of our class A
common stock on Nasdaq was $2.098 per share.


                                  -----------

  Investing in our class A common stock involves a high degree of risk. See
"Risk Factors" beginning on page 6.

                                  -----------

  The Securities and Exchange Commission and state securities regulators have
not approved or disapproved of these securities or determined whether this
prospectus is truthful or complete. Any representation to the contrary is a
criminal offense.

through web, wireless and voice communication channels. Our product line
enables both proactive and interactive delivery of information from large-scale
databases. Our objective is to provide businesses with a software platform to
develop solutions that deliver insight and intelligence to their enterprises,
customers and supply-chain partners.

   Our software platform enables users to query and analyze the most detailed,
transaction-level databases, turning data into business intelligence. In
addition to supporting internal enterprise users, the platform delivers
critical business information beyond corporate boundaries to customers,
partners and supply-chain constituencies through a broad range of communication
channels such as the Internet, e-mail, telephone and wireless communication
devices. Our platform is designed for developing business intelligence
solutions that are personalized and proactive and that reach millions of users.
We offer a comprehensive set of consulting, education and technical support
services for our customers and partners.

   Our principal corporate offices are located in McLean, Virginia. We also
maintain domestic sales offices throughout the United States and international

International sales accounted for 24.9%, 24.0% and 26.1% of our total revenues
in 2000, 1999 and 1998, respectively.

   In July 1999, we launched a new business unit called Strategy.com offering a
hosted messaging platform enabling third party content providers to offer their
customers highly personalized, timely information services through e-mail,
telephone and wireless devices. In August 2001, Strategy.com became a wholly-
owned subsidiary of MicroStrategy. In September 2001, MicroStrategy determined
that it would significantly reduce operations at Strategy.com and eliminate
Strategy.com's sales, marketing and research and development efforts.

                                 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 our company. 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.

We have experienced losses in the past and expect future losses through at
least the end of 2001

   We have not achieved profitability and have incurred significant operating
losses in each of the last five years. We incurred net losses of $53.9 million
in the six months ended June 30, 2001 and $261.3 million, $33.7 million and
$2.3 million in the years ended December 31, 2000, 1999 and 1998,
respectively. As of June 30, 2001, our accumulated deficit was $353.1 million.
We expect our gross revenue to decline from the fiscal year ended December 31,
2000 to the fiscal year ending December 31, 2001. In connection with our April
2001 corporate restructuring and the additional Strategy.com restructurings in
April and May 2001, we recorded restructuring and impairment charges in the
second quarter of 2001 of $43.1 million.

   We expect that we will not achieve sufficient revenue to become profitable
through at least the end of 2001. Even if we do achieve profitability, we
cannot assure you that we can sustain or increase profitability on a quarterly
or annual basis in the future. If revenue grows more slowly than we
anticipate, or if operating expenses exceed our expectations or cannot be
adjusted accordingly, our business, results of operations and financial
condition will be materially and adversely affected.

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 may 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 as a result of:

  . the size, timing 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;

  . the timing of new product announcements;

  . 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 success in adding to our indirect distribution channels;

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

                                       6


  . changes in foreign currency exchange rates; and

  . seasonal factors, such as our traditionally lower pace of new sales in
    the summer.

   Limited Ability to Adjust Expenses. We base our operating expense budgets on
expected revenue trends. Many of our expenses, such as office and equipment
leases, 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.

We may lose sales, or sales may be delayed, due to the long sales and
implementation cycles for our products, which would 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 they seek internal approval for the
purchase of our products and/or services. During this long sales cycle, events
may occur that affect the size 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 varies widely from one customer to the next.
Implementing our product can sometimes last 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 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 employees, investors, customers, vendors and lenders may react adversely to
the revision of our 1999, 1998 and 1997 revenues and operating results

   Our future success depends in large part on the support of our key
employees, investors, customers, vendors and lenders, who may react adversely
to the revision of our 1999, 1998 and 1997 revenues and operating results. The
revision of our 1999, 1998 and 1997 revenues and operating results has resulted
in substantial amounts of negative publicity about us and we believe that this
publicity has caused some of our potential customers to defer purchases of our
software or to do business with other vendors. We may not be able to retain key
employees and customers if they lose confidence in us, and our vendors and
lenders may reexamine their willingness to do business with us. In addition,
investors may lose confidence, which may cause the trading price of our class A
common stock to decrease. If we lose the services of our key employees or are
unable to retain and attract our existing and new customers, vendors and
lenders, our business, operating results and financial condition could be
materially and adversely affected.

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

   Our deferred revenue was approximately $70.5 million as of June 30, 2001.
The timing and ultimate recognition of our deferred revenue depend on 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 at any particular date may not be representative of
actual revenue for any succeeding period.

                                       7


We may need additional financing which could be difficult to obtain

   We may require additional external financing through credit facilities, sale
of additional debt or equity securities in MicroStrategy or by obtaining other
financing facilities to support our operations, as we expect to incur operating
losses through at least the third quarter of 2001 and possibly longer.
Obtaining additional financing will be subject to a number of factors,
including:

  . market conditions;

  . our operating performance; and

  . investor sentiment.

   These factors may make the timing, amount, terms and conditions of
additional financing unattractive to us. If we are unable to raise capital
needed to fund our operations, our business, operating results and financial
condition may be materially and adversely affected.

We face litigation that could have a material adverse effect on our business,
financial condition and results of operations

   We and certain of our directors and executive officers are named as
defendants in a private securities class action lawsuit and a shareholder
derivative lawsuit relating to the restatement of our 1999, 1998 and 1997
financial results. Although we have entered into agreements to settle such
lawsuits and the settlements have received court approval, both settlements are
subject to various closing conditions. If the agreed upon settlements are not
consummated, it is possible that we may be required to pay substantial damages
or settlement costs which could have a material adverse effect on our financial
condition or results of operation. Regardless of the outcome of these matters,
it is likely that we will incur substantial defense costs and that these
actions may cause a diversion of management time and attention.

The issuance of class A common stock as part of the proposed settlement of
class action litigation and the exercise of warrants or conversion of notes
issued as part of the litigation settlement could result in a substantial
number of additional shares of class A common stock being issued

   The agreements we entered into to settle the private securities class action
lawsuit and the derivative suit relating to the restatement of our 1999, 1998
and 1997 financial results require us to issue to members of the class
2,777,778 shares of class A common stock. At the time of that issuance, some of
our officers will tender to us for no consideration 1,683,502 shares of class A
common stock for cancellation, resulting in a net issuance of 1,094,276 shares
of class A common stock. In addition, the settlement agreements require the
issuance of warrants to purchase 1,900,000 shares of class A common stock and
five-year unsecured subordinated promissory notes having an aggregate principal
amount of $80.5 million. We would have the option at any time prior to the
expiration of the five-year term of the notes to convert the notes into a
number of shares of class A common stock equal to the principal amount of the
notes being converted divided by 80% of the dollar volume-weighted average
trading price of the class A common stock over a ten-day period preceding our
delivery of a notice of conversion, which could result in a substantial number
of shares of class A common stock being issued. For example, if the conversion
price of the notes were based on the dollar volume-weighted average trading
price of the class A common stock during the 10 trading days ending October 1,
2001, we would be obligated to issue 65,243,468 shares of class A common stock
if we elected to convert the notes. The issuance of a substantial number of
shares of class A common stock as part of the litigation settlement and future
exercises or conversions of securities issued in the litigation settlement may
result in substantial dilution to the interests of holders of class A common
stock and may result in downward pressure on the price of our class A common
stock.


                                       8


The conversion of the shares of our preferred stock could result in substantial
numbers of additional shares of class A common stock being issued if our market
price declines during periods in which the conversion price of the preferred
stock may adjust

   On June 14, 2001, holders of our series A preferred stock exchanged 11,850
shares of series A preferred stock for cash and shares of our class A common
stock, series B preferred stock, series C preferred stock, series D preferred
stock and series E preferred stock. On September 10, 2001, we redeemed all 630
outstanding shares of series E preferred stock. The series B preferred stock,
series C preferred stock and series D preferred stock are convertible into
shares of our class A common stock at conversion prices currently equal to
$12.50, $17.50 and $5.00 per share, respectively. The outstanding shares of
series B preferred stock, series C preferred stock and series D preferred stock
would currently convert into 7,492,200 shares of class A common stock, plus a
number of shares reflecting accrued but unpaid dividends as of the conversion
date. However, if the holders of the series B preferred stock and series C
preferred stock do not convert their shares into shares of class A common stock
prior to their maturity three years from the date of issuance, and if we do not
redeem their outstanding shares of series B preferred stock and series C
preferred stock at maturity, the conversion price for such shares will be reset
to a price equal to 95% of the dollar volume-weighted average price of our
class A common stock for the 30 trading days prior to the maturity date. If the
market price at maturity of our class A common stock is less than the
applicable conversion price, the number of shares of class A common stock that
we could be required to issue upon conversion of the series B preferred stock
and series C preferred stock would increase. For instance, if the market price
of our class A common stock on the maturity date of our series B preferred
stock and series C preferred stock were $1.20, the closing sale price of our
class A common stock as of October 1, 2001, the holders of the series B
preferred stock and series C preferred stock did not elect to convert any of
their shares prior to the maturity date and we did not redeem such shares on
the maturity date, we would be required to issue a total of 50,791,667 shares
of our class A common stock upon conversion of such shares at maturity plus a
number of shares reflecting accrued but unpaid dividends.


   After the exchange of shares of our series A preferred stock for shares of
our class A common stock, series B preferred stock, series C preferred stock,
series D preferred stock and series E preferred stock as described above, 650
shares of our series A preferred stock remain outstanding. We have the right to
redeem 120 of such shares through December 11, 2001. As of October 1, 2001,
shares of series A preferred stock are convertible into class A common stock at
a conversion price equal to $3.08313 per share. If any shares of series A
preferred stock remain outstanding on June 19, 2002, the conversion price may
be adjusted based on the average of the dollar volume-weighted average price of
our class A common stock during the ten trading days after that date and on
each subsequent anniversary of that date, if such adjustment would result in a
lower conversion price. The conversion price of the series A preferred stock
may also be adjusted upon the occurrence of various events, including the
failure to maintain the effectiveness of the registration statement to which
these shares relate and the issuance of certain equity securities. As a result,
the lower the price of our class A common stock at these intervals, the greater
the number of shares the holder will receive upon conversion after any such
adjustment.


   To the extent the shares of our preferred stock are converted or dividends
on these shares are paid in shares of class A common stock rather than cash, a
significant number of shares of class A common stock may be sold into the
market, which could decrease the price of our class A common stock and
encourage short sales. Short sales could place further downward pressure on the
price of our class A common stock. In that case, we could be required to issue
an increasingly greater number of shares of our class A common stock upon
future conversions of the series A preferred stock, series B preferred stock
and series C preferred stock as a result of the annual and other adjustments
described above, sales of which could further depress the price of our class A
common stock.

   The conversion of and the payment of dividends in shares of class A common
stock in lieu of cash on the preferred stock may result in substantial dilution
to the interests of other holders of our class A common stock.

                                       9


No holder may convert its preferred stock if upon such conversion the holder
together with its affiliates would have acquired a number of shares of class A
common stock during the 60-day period ending on the date of conversion which,
when added to the number of shares of class A common stock held at the
beginning of such 60-day period, would exceed 9.99% of our then outstanding
class A common stock, excluding for purposes of such determination shares of
class A common stock issuable upon conversion of shares of preferred stock
which have not been converted. Nevertheless, a holder may still sell a
substantial number of shares in the market. By periodically selling shares into
the market, an individual holder could eventually sell more than 9.99% of our
outstanding class A common stock while never holding more than 9.99% at any
specific time.

We may be required to pay substantial penalties to the holders of the preferred
shares if specific events occur

   In accordance with the terms of the agreements relating to the issuance of
our redeemable convertible preferred stock, we are required to pay substantial
penalties to a holder of preferred stock under specified circumstances,
including, among others:

  . nonpayment of dividends on the series A preferred stock, series B
    preferred stock and series C preferred stock in a timely manner;

  . failure to deliver shares of our class A common stock upon conversion of
    the preferred shares after a proper request;

  . nonpayment of the redemption price at maturity of any remaining series A
    preferred stock, series B preferred stock and series C preferred stock;
    or

  . the unavailability of the registration statement relating to the shares
    of class A common stock issuable upon conversion of and in lieu of cash
    dividends on the preferred stock to cover the resale of such shares for
    more than brief intervals.

   These penalties are generally paid in the form of interest payments, subject
to any restrictions imposed by applicable law. In the third quarter of 2000, we
incurred $578,000 in penalties as a result of a 14-day delay in the filing of a
registration statement registering the shares of class A common stock issuable
upon conversion of and in lieu of dividends on the series A preferred stock.

We are currently unable to borrow additional amounts under our master equipment
lease agreement

   We signed a three-year master lease agreement to lease up to $40.0 million
of computer equipment in November 1999, of which we have leased approximately
$17.8 million as of September 30, 2001. Future drawdowns and interest rates
under the lease agreement are subject to our credit worthiness. Currently, we
are not able to draw down additional amounts under the lease agreement.


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, customer relationship
management applications, portals and narrowcast messaging technologies are
intensely competitive and subject to rapidly changing technology.

                                       10


In addition, many of our competitors in these markets are offering, or may soon
offer, products and services that may compete with MicroStrategy products.

   MicroStrategy's most direct competitors provide:

  . business intelligence software;

  . online analytical processing, or OLAP, tools;

  . query and reporting tools;

  . web-based static reporting tools;

  . information delivery and proactive reporting;

  . analytical customer relationship management products;

  . web traffic analysis applications; and

  . marketing automation.

   Each of these markets are discussed more fully below.

   Business Intelligence Software. Makers of business intelligence software
provides business intelligence capabilities designed for integration,
customization and application development. Leading industry analysts classify
companies such as Microsoft, Oracle, Hyperion, SAP and SAS to be leading
providers of business intelligence software.

   OLAP Tools. Companies that build software to perform OLAP provide offerings
competitive with the core MicroStrategy 7 platform. Whether web-based or
client-server, these tools give end users the ability to query underlying data
sources without having to hand code structured query language queries. Most
OLAP tools allow users to build their own calculations and specify report
layouts and other options. Additionally, OLAP tools provide users the ability
to navigate throughout the underlying data in an easy, graphical mode, often
referred to as drilling. Providers of OLAP tools include Cognos, Hyperion,
Brio, IBM, Seagate and Microsoft.

   Query and Reporting Tools. Query and reporting tools allow large numbers of
end users to gain access to pre-defined reports for simple analysis. Often the
end users are able to specify some sort of run-time criteria that customizes
the result set for that particular person. Some limited "drilling' is also
provided. Companies that produce query and reporting tools include Business
Objects, Cognos, Oracle, Seagate and Brio.

   Web-based Static Reporting Tools. Companies that offer software to deliver
pre-built reports for end-user viewing and consumption can also compete with
MicroStrategy. These applications often lack the sophistication, robustness and
scalability of MicroStrategy applications, but can be attractive for small,
departmental applications. Vendors in this category include Actuate, Business
Objects, Seagate, Microsoft, Computer Associates and SAS.

   Information Delivery and Proactive Reporting. Companies that focus on the
proactive delivery of information, via e-mail, website, or other medium can
compete with our offerings. Typically these tools serve to push out compiled
reports on a scheduled basis to sets of users based on job type. Our software
has this technology integrated into its core platforms. Vendors of such
technology include Actuate, nQuire, Information Builders and Business Objects.

   Analytical Customer Relationship Management Products. Companies that deliver
customer relationship management products alone or in conjunction with e-
commerce applications, such as Broadbase, BroadVision, E.piphany and Vignette,
compete with our analytical customer relationship management applications. In
contrast with providers of operational customer relationship management
vendors, such as Vantive and Oracle, analytical customer relationship
management deals more with customer segmentation, analysis and interaction as
opposed to infrastructure and call centers.

                                       11


   Web Traffic Analysis Applications. Reporting and analysis tools can be
specialized to analyze visitors to a company's website. Typically this involves
extracting data from a web-log file and importing it into a usable format,
often in a relational database. A set of analysis, sometimes customer-centric
in nature, is performed, and limited ad-hoc reporting is permitted. Advanced
applications in this space merge data from the web-logs with other customer
centric attributes to help provide a complete view of the customer base.
Vendors in this space include Accrue, Net.Genesis and WebTrends.

   Marketing Automation. Applications focused on the automation and execution
of marketing tasks, such as campaign management and delivery, compete with our
customer relationship management products and our Narrowcast Server platform.
Leading vendors in this space include E.piphany, Xchange, Chordiant and
Broadbase.

   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 cannot be sure that we will
be able to compete successfully against current and future competitors or that
the competitive pressures we face will not 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 harm our ability to obtain maintenance revenues for
new and existing product licenses on favorable terms.

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 would 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. In
the second and third quarters of 2001, we implemented corporate restructuring
plans which included a reduction in our worldwide workforce of approximately
one-third. These reductions in force could adversely impact our employee morale
and our ability to attract and retain employees. Our future success also
depends in large part on the continued service of key management personnel,
particularly Michael J. Saylor, our Chairman 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.

Our inability to develop and release product enhancements and new products to
respond to rapid technological change in a timely and cost-effective manner
would have a material adverse effect on our business, operating results and
financial condition

   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

                                       12


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 to develop and test major 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, introductions of new competitive products or
customer requirements, nor can we be sure that our new products and product
enhancements will achieve market acceptance.

The emergence of new industry standards may adversely affect our ability to
market 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. Although the core database component of our
business intelligence solutions is compatible with nearly all enterprise server
hardware and operating system combinations, such as OS/390, AS/400, Unix and
Windows, our application server component runs only on the Windows NT operating
system. Therefore, our ability to increase sales currently depends on the
continued acceptance of the Windows NT operating system. We cannot market many
of our current business intelligence products to potential customers who use
Unix operating systems as their application server. We would have to invest
substantial resources to develop a Unix product and we cannot be sure that we
could introduce such a product on a timely or cost- effective basis, if at all.

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 would 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 may impair the further growth of this market, as may other
developments. We cannot be sure that this market will continue to 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.

Because of the rights of our two classes of common stock, and because we are
controlled by our existing stockholders, these stockholders could transfer
control of MicroStrategy to a third party without anyone else's approval or
prevent a third party from acquiring MicroStrategy

   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

                                       13



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 September 30, 2001, holders of
our class B common stock owned or controlled 49,421,262 shares of class B
common stock, or 92.1% of the total voting power. Michael J. Saylor, our
Chairman and Chief Executive Officer, controlled 2,749,106 shares of class A
common stock and 38,581,556 shares of class B common stock, or 72.4% of total
voting power, as of September 30, 2001. 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 bylaws and take
other actions requiring the vote or consent of stockholders, including mergers,
going private transactions and other extraordinary transactions and their
terms.


   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 seeking anyone else's
approval, 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 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.

We rely on our strategic channel partners and if we are unable to develop or
maintain successful relationships with them, our business, operating results
and financial condition will suffer

   In addition to our direct sales force, we rely on strategic channel
partners, such as original equipment manufacturers, system integrators and
value-added resellers, to license and support our products in the United States
and internationally. In particular, for the six months ended June 30, 2001 and
the years ended December 31, 2000, 1999 and 1998, channel partners accounted
for, directly or indirectly, approximately 35.3%, 44.4%, 39.2% and 33.6% of our
total product license revenues, respectively. Our channel partners generally
offer customers the products of several different companies, including some
products that compete with ours. Although we believe that direct sales will
continue to account for a majority of product license revenues, we intend to
increase the level of indirect sales activities through our strategic channel
partners. However, we may not be successful in our efforts to continue to
expand indirect sales in this manner. We may not be able to attract strategic
partners who will market our products effectively and who will be qualified to
provide timely and cost-effective customer support and service. Our ability to
achieve revenue growth in the future will depend in part on our success in
developing and maintaining successful relationships with those strategic
partners. If we are unable to develop or maintain our relationships with these
strategic partners, our business, operating results and financial condition
will suffer.

We have only limited protection for our proprietary rights in our software,
which makes it difficult to prevent third parties from infringing upon our
rights

   We rely primarily on a combination of copyright, patent, trademark and trade
secret laws, customer licensing agreements, employee and third-party
nondisclosure agreements and other methods to protect our proprietary rights.
However, these laws and contractual provisions provide only limited protection.
Despite our efforts to protect our proprietary rights, unauthorized parties may
attempt to copy or otherwise obtain and use our products or technology.
Policing such unauthorized use is difficult, and we cannot be certain that we
can prevent it, particularly in countries where the laws may not protect our
proprietary rights as fully as in the United States.

Our products may be susceptible to claims by other companies that our products
infringe upon their proprietary rights, which could adversely affect our
business, operating results and financial condition

   As the number of software products in our target markets increases and the
functionality of these products further overlaps, we may become increasingly
subject to claims by a third party that our technology infringes

                                       14


such party's proprietary rights. Regardless of their merit, any such claims
could be time consuming and expensive to defend, may divert management's
attention and resources, could cause product shipment delays and could require
us to enter into costly royalty or licensing agreements. If successful, a claim
of infringement against us and our inability to license the infringed or
similar technology could have a material adverse effect on our business,
operating results and financial condition.

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

   International sales accounted for 31.6%, 24.9%, 24.0% and 26.1% of our total
revenues for the six months ended June 30, 2001 and the years ended December
31, 2000, 1999 and 1998, 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 and other trade barriers;

  . costs of localizing products for foreign countries;

  . lack of acceptance of localized products in foreign countries;

  . longer accounts receivable payment cycles;

  . difficulties in managing international operations;

  . tax issues, including restrictions on repatriating earnings;

  . weaker intellectual property protection in other countries; and

  . the burden of complying with a wide variety of foreign laws.

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

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 or defects,
especially when first or subsequent versions are released. Although we test our
products extensively, we have in the past discovered software errors in new
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 or delays in
market acceptance, which could have a material adverse effect upon our
business, operating results and financial condition.

   Our license agreements with customers typically contain provisions designed
to limit our exposure to product liability claims. It is possible, however,
that these provisions may not be effective under the laws of certain domestic
or international jurisdictions. Although there have been no product liability
claims against us to date, our license and support of products may involve the
risk of these claims. A successful product liability claim against us could
have a material adverse effect on our business, operating results and financial
condition.

                                       15


The price of our stock may be extremely volatile

   The market price for our class A common stock has historically been volatile
and could fluctuate significantly for any of the following reasons:

  . quarter-to-quarter variations in our operating results;

  . developments or disputes concerning proprietary rights;

  . technological innovations or new products;

  . governmental regulatory action;

  . general conditions in the software industry;

  . increased price competition;

  . changes in revenue or earnings estimates by analysts;

  . any change in the actual or expected amount of dilution attributable to
    issuances of additional shares of class A common stock upon conversion of
    our preferred stock or as a result of the litigation settlement; or

  . other events or factors.

   Many of the above factors are beyond our control.

   The stock market has recently experienced extreme price and volume
fluctuations. These fluctuations have particularly affected the market price of
many software companies, often without regard to their operating performance.

                                       16


                                USE OF PROCEEDS

   If all of the warrants were exercised for cash, we would receive aggregate
gross cash proceeds from the sale of 1,900,000 shares of Class A Common Stock
of approximately $76,000,000. However, the warrants may be exercised by the
surrender of notes issued by us to the class members pursuant to the settlement
agreement as payment of the exercise price, valued for this purpose at 133% of
the principal amount and all accrued and unpaid interest on the notes so
surrendered. Therefore, the amount of any cash proceeds that we may receive
upon the exercise of the warrants is uncertain.

   We intend to use the proceeds received upon any exercise of the warrants for
working capital and other general corporate proposals.

   We will bear all costs, fees and expenses incurred in effecting the
registration of the shares covered by this prospectus, including, without
limitation, all registration and filing fees, Nasdaq listing fees, fees and
expenses of our counsel, fees and expenses of our accountants, and blue sky
fees and expenses.

                              PLAN OF DISTRIBUTION

   We are registering the shares of class A common stock issuable upon exercise
of warrants to be issued to class members pursuant to a settlement agreement
among us, some of our officers and directors and plaintiffs' counsel, approved
by the United States District Court for the Eastern District of Virginia on
April 2, 2001, relating to a consolidated class action lawsuit filed against
us, some of our officers and directors and our independent accountants. We will
issue the shares directly to the holders of the warrants, upon exercise of such
warrants, from time to time after the date of this prospectus. The warrants
expire five years from the date of issue.

   We will pay all expenses of the registration of the shares of class A common
stock pursuant to the settlement agreement, estimated to be $100,000 in total,
including, without limitation, SEC filing fees and expenses of compliance with
state securities or "blue sky" laws.

                                 LEGAL MATTERS

   The validity of the shares of class A common stock offered by this
prospectus has been passed upon by Hale and Dorr LLP, Boston, Massachusetts.

                                    EXPERTS

   The financial statements incorporated in this registration statement by
reference to the Annual Report on Form 10-K for the year ended December 31,
2000, as amended, have been so incorporated in reliance on the report of
PricewaterhouseCoopers LLP, independent accountants, given on the authority of
said firm as experts in auditing and accounting.

Item 15. Indemnification of Directors and Officers.

   Section 102 of the Delaware General Corporation Law allows a corporation to
eliminate the personal liability of directors of a corporation to the
corporation or its stockholders for monetary damages for a breach of fiduciary
duty as a director, except where the director breached his duty of loyalty,
failed to act in good faith, engaged in intentional misconduct or knowingly
violated a law, authorized the payment of a dividend or approved a stock
repurchase in violation of Delaware corporate law or obtained an improper
personal benefit. MicroStrategy has included such a provision in its
Certificate of Incorporation.

   Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if such
person had no reasonable cause to believe his conduct was unlawful; provided
that, in the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such
person shall have been adjudged to be liable to the corporation unless and only
to the extent that the adjudicating court determines that such indemnification
is proper under the circumstances.

   MicroStrategy's certificate of incorporation provides that an officer or
director of MicroStrategy will not be personally liable to MicroStrategy or its
stockholders for monetary damages for any breach of his fiduciary duty as an
officer or director, except in certain cases where liability is mandated by the
Delaware General Corporation Law. The provision has no effect on any non-
monetary remedies that may be available to MicroStrategy or its stockholders,
nor does it relieve MicroStrategy or its officers or directors from compliance
with federal or state securities laws. MicroStrategy's certificate of
incorporation also generally provides that MicroStrategy shall indemnify, to
the fullest extent permitted by law, any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit, investigation, administrative hearing or any other proceeding by reason
of the fact that he is or was a director or officer of MicroStrategy, or is or
was serving at the request of MicroStrategy as a director, officer, employee or
agent of another entity, against expenses incurred by him in connection with
such proceeding. An officer or director shall not be entitled to
indemnification by MicroStrategy if the officer or director did not act in good
faith and in a manner reasonably believed to be in, or not opposed to, the best
interests of the MicroStrategy, or with respect to any criminal action or
proceeding, the officer or director had reasonable cause to believe his conduct
was unlawful.

                                      II-1


   MicroStrategy has purchased directors' and officers' liability insurance
which would indemnify its directors and officers against damages arising out of
certain kinds of claims which might be made against them based on their
negligent acts or omissions while acting in their capacity as such.

Item 17. Undertakings.

   The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this Registration Statement:

       (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933, as amended (the "Securities Act");

       (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this Registration Statement (or the most recent
    post- effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in this Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in the volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than 20 percent change in
    the maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective Registration Statement; and

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in this Registration Statement
    or any material change to such information in this Registration
    Statement;

    provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
    the information required to be included is a post-effective amendment
    by those paragraphs is contained in periodic reports filed by the
    Company pursuant to Section 13 or Section 15(d) of the Securities
    Exchange Act of 1934, as amended (the "Exchange Act"), that are
    incorporated by reference in this Registration Statement.

     (2) That, for the purposes of determining any liability under the
  Securities Act, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at the
  time shall be deemed to be the initial bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

                                      II-2


   The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the indemnification provisions described herein, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

                                      II-3


                                   SIGNATURES

duly authorized, in the City of Vienna, Commonwealth of Virginia, on October
