         The Registrant's Annual Report on Form 10-K was not filed on March 30,

Registrant filed a Current Report on Form 8-K disclosing that the Registrant,
with the concurrence of PricewaterhouseCoopers LLP, its auditors, would revise
its 1998 and 1999 reported revenue and operating results to conform to existing
accounting principles articulated in Statement of Position 97-2. Following
completion of these revisions, the Registrant's Annual Report on Form 10-K will
be filed promptly, and in no event later than the fifteenth day following the
prescribed due date.

Washington, D.C. 20549

Gentlemen:

This letter is written in response to the requirement of Rule 12b-25(c) under
the Securities Exchange Act of 1934 and in satisfaction of Item (c) of Part II
of Form 12b-25.

We are the independent auditors of MicroStrategy Incorporated (the
"Registrant").  The Registrant has stated in Part III of its filing on Form
12b-25 that it was unable to timely file, without unreasonable effort or
expense, its Annual Report on Form 10-K for the year ended December 31, 1999
because our firm had not yet delivered our report relating to the financial
statements of the Registrant for the year ended December 31, 1999 and was
therefore unable to furnish the required opinion on such financial statements.

We hereby advise you that we have read the statements made by the Registrant in
Part III of its filing on Form 12b-25 and agree with the statements made
therein.  We are unable to complete our audit of the Registrant's financial
statements and furnish the required opinion for a timely filing because we did
not have the ability to complete the auditing procedures which we consider
necessary under the circumstances.


                                        Very truly yours,

                                        PRICEWATERHOUSECOOPERS LLP


                                        /s/ PricewaterhouseCoopers LLP
                                        ------------------------------
