                                                                          PAGE 1


                          REGISTRATION RIGHTS AGREEMENT


     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of June 17,
2000, by and among MicroStrategy, Incorporated, a Delaware corporation, with
headquarters located at 8000 Towers Crescent Drive, Vienna, Virginia 22182 (the
"Company"), and the undersigned buyers (each, a "Buyer" and collectively, the
"Buyers").

     WHEREAS:

     A. In connection with the Securities Purchase Agreement by and among the
parties hereto of even date herewith (the "Securities Purchase Agreement"), the
Company has agreed, upon the terms and subject to the conditions of the
Securities Purchase Agreement, to issue and sell to the Buyers shares of the
Company's Series A Convertible Preferred Stock (the "Preferred Shares"), which
will be convertible into shares of the Company's Class A common stock, par value
$0.001 per share (the "Common Stock") (as converted, the "Conversion Shares") in
accordance with the terms of the Company's Certificate of Designations,
Preferences and Rights of the Preferred Stock (the "Certificate of
Designations");

     B. To induce the Buyers to execute and deliver the Securities Purchase
Agreement, the Company has agreed to provide certain registration rights under
the Securities Act of 1933, as amended, and the rules and regulations
thereunder, or any similar successor statute (collectively, the "1933 Act"), and
applicable state securities laws.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and each of the Buyers
hereby agree as follows:

     1. DEFINITIONS.

        c. "Register," "registered," and "registration" refer to a registration
effected by
<PAGE>

                                                                          PAGE 2

preparing and filing one or more Registration Statements (as defined below) in
compliance with the 1933 Act and pursuant to Rule 415 under the 1933 Act or any
successor rule providing for offering securities on a continuous or delayed
basis ("Rule 415"), and the declaration or ordering of effectiveness of such
Registration Statement(s) by the United States Securities and Exchange
Commission (the "SEC").

        d. "Registrable Securities" means (i) the Conversion Shares issued or
issuable upon conversion of the Preferred Shares, (ii) the Dividend Shares (as
defined in the Certificate of Designations) issued in relation to the Preferred
Shares and (iii) any shares of capital stock issued or issuable with respect to
the Conversion Shares, the Preferred Shares or the Dividend Shares issued in
relation to the Preferred Shares as a result of any stock split, stock dividend,
recapitalization, exchange or similar event or otherwise, without regard to any
limitations on conversions of Preferred Shares.

        e. "Registration Statement" means a registration statement or
registration statements of the Company filed under the 1933 Act covering the
Registrable Securities.

Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings set forth in the Securities Purchase Agreement.

     2. REGISTRATION.
        ------------

        a. Mandatory Registration. The Company shall prepare, and, as soon as
        ----------------------
practicable but in no event later than 30 days after the Initial Closing Date
(as defined in the Securities Purchase Agreement) (the "Filing Deadline"), file
with the SEC the Registration Statement on Form S-3 covering the resale of all
of the Registrable Securities. In the event that Form S-3 is unavailable for
such a registration, the Company shall use such other form as is available for
such a registration, subject to the provisions of Section 2(d). The Registration
Statement prepared pursuant hereto shall register for resale at least that
number of shares of Common Stock equal to the product of (x) 1.25 and (y) the
number of Registrable Securities as of the trading day immediately preceding the
date the Registration Statement is initially filed with the SEC (after giving
effect to the Mandatory Closing (as defined in the Securities Purchase
Agreement), if any), subject to adjustment as provided in Section 2(e). The
Company shall use its best efforts to have the Registration Statement declared
effective by the SEC as soon as practicable, but in no event later than the date
which is 180 days after the Initial Closing Date (the "Effectiveness Deadline").


        b. Allocation of Registrable Securities. The initial number of
           ------------------------------------
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC. In the event that an Investor sells or otherwise transfers any of such
Investor's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable
<PAGE>

                                                                          PAGE 3

Securities included in such Registration Statement for such transferor. Any
shares of Common Stock included in a Registration Statement and which remain
allocated to any Person which ceases to hold any Registrable Securities covered
by such Registration Statement shall be allocated to the remaining Investors,
pro rata based on the number of Registrable Securities then held by such
Investors which are covered by such Registration Statement.

        c. Legal Counsel. Subject to Section 5 hereof, the Buyers holding at
           -------------
least two-thirds (2/3) of the Registrable Securities shall have the right to
select one legal counsel to review and oversee any offering pursuant to this
Section 2 ("Legal Counsel"), which shall be Katten Muchin Zavis or such other
counsel as thereafter designated by the holders of at least two-thirds (2/3) of
the Registrable Securities. The Company shall reasonably cooperate with Legal
Counsel in performing the Company's obligations under this Agreement.

        d. Ineligibility for Form S-3. In the event that Form S-3 is not
           --------------------------
available for the registration of the resale of Registrable Securities
hereunder, the Company shall (i) register the resale of the Registrable
Securities on another appropriate form reasonably acceptable to the holder of at
least two-thirds (2/3) of the Registrable Securities and (ii) undertake to
register the Registrable Securities on Form S-3 as soon as such form is
available, provided that the Company shall maintain the effectiveness of the
Registration Statement then in effect until such time as a Registration
Statement on Form S-3 covering the Registrable Securities has been declared
effective by the SEC.

        e. Sufficient Number of Shares Registered. In the event the number of
           --------------------------------------
shares available under a Registration Statement filed pursuant to Section 2(a)
is insufficient to cover all of the Registrable Securities required to be
covered by such Registration Statement or an Investor's allocated portion of the
Registrable Securities pursuant to Section 2(b), the Company shall amend the
Registration Statement, or file a new Registration Statement (on the short form
available therefor, if applicable), or both, so as to cover at least 125% of the
number of such Registrable Securities as of the trading day immediately
preceding the date of the filing of such amendment or new Registration
Statement, in each case, as soon as practicable, but in any event not later than
fifteen (15) days after the necessity therefor arises. The Company shall use it
best efforts to cause such amendment and/or new Registration Statement to become
effective as soon as practicable following the filing thereof. For purposes of
the foregoing provision, the number of shares available under a Registration
Statement shall be deemed "insufficient to cover all of the Registrable
Securities" if at any time the number of Registrable Securities issued or
issuable upon conversion of the Preferred Shares covered by such Registration
Statement is greater than the number of shares of Common Stock available for
resale under such Registration Statement. The calculation set forth in the
foregoing sentence shall be made without regard to any limitations on the
conversion of the Preferred Shares and such calculation shall assume that the
Preferred Shares are then convertible into shares of Common Stock at the then
prevailing Conversion Rate (as defined in the Certificate of Designations).

        f. Effect of Failure to File and Obtain and Maintain Effectiveness of
           ------------------------------------------------------------------
Registration Statement. If, other than solely as a result of an Investor Delay
----------------------
(as defined below), (i) a Registration Statement covering all the Registrable
Securities and required to be filed by the Company
<PAGE>

                                                                          PAGE 4

pursuant to this Agreement is not (A) filed with the SEC on or before the Filing
Deadline or (B) declared effective by the SEC on or before the Effectiveness
Deadline or (ii) on any day after the Registration Statement has been declared
effective by the SEC sales of all the Registrable Securities required to be
included on such Registration Statement cannot be made (other than during an
Allowable Grace Period (as defined in Section 3(r)) pursuant to the Registration
Statement (including, without limitation, because of a failure to keep the
Registration Statement effective, to disclose such information as is necessary
for sales to be made pursuant to the Registration Statement or to register
sufficient shares of Common Stock), then, as partial relief for the damages to
any holder by reason of any such delay in or reduction of its ability to sell
the underlying shares of Common Stock (which remedy shall not be exclusive of
any other remedies available at law or in equity), the Company shall pay to each
holder of Preferred Shares an amount in cash per Preferred Share held equal to
the product of (A) $10,000 multiplied by (B) the product of (I) 0.00033
multiplied by (II) the sum of (x) the number of days after the Filing Deadline
that such Registration Statement is not filed with the SEC, plus (y) the number
of days after the Effectiveness Deadline that the Registration Statement is not
declared effective by the SEC, plus (z) the number of days after the
Registration Statement has been declared effective by the SEC that such
Registration Statement is not available (other than during an Allowable Grace
Period) for the sale of at least all the Registrable Securities required to be
included on such Registration Statement pursuant to section 2(e). The payments
to which a holder shall be entitled pursuant to this Section 2(f) are referred
to herein as "Registration Delay Payments." Registration Delay Payments shall be
paid on the earlier of (I) the last day of the calendar month during which such
Registration Delay Payments are incurred and (II) the third business day after
the event or failure giving rise to the Registration Delayed Payments is cured.
In the event the Company fails to make Registration Delay Payments in a timely
manner, such Registration Delay Payments shall bear interest at the rate of 1.5%
per month (prorated for partial months) until paid in full. An "Investor Delay"
shall mean any period for which the Registration Statement is not effective or
sales of Registrable Securities may not be made solely attributable to changes
required by the Investors in the Registration Statement after the Registration
Statement has been declared effective by the SEC with respect to information
required by this Agreement to be provided to the Company by such Investors for
purposes of inclusion in the Registration Statement, with respect to changes in
the plan of distribution or the failure of the Investors to conduct their review
of the Registration Statement pursuant to Section 3(c) of this Agreement within
five (5) days of their receipt of the Registration Statement.

     3. RELATED OBLIGATIONS.
        -------------------

     At such time as the Company is obligated to file a Registration Statement
with the SEC pursuant to Section 2(a) or 2(e), the Company will use its best
efforts to effect the registration of the Registrable Securities in accordance
with the intended method of disposition thereof and, pursuant thereto, the
Company shall have the following obligations:

        a. The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the Registrable Securities (but in no
event later than the Filing Deadline) and use its best efforts to cause such
Registration Statement relating to the Registrable Securities to become
effective as soon as practicable after such filing (but in no event later than
the Effectiveness
<PAGE>

                                                                          PAGE 5

Deadline). The Company shall keep each Registration Statement effective pursuant
to Rule 415 at all times until the earlier of (i) the date as of which the
Investors may sell all of the Registrable Securities covered by such
Registration Statement without restriction pursuant to Rule 144(k) (or successor
thereto) promulgated under the 1933 Act or (ii) the date on which the Investors
shall have sold all the Registrable Securities covered by such Registration
Statement (the "Registration Period"), which Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein) shall
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein, or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading. The term
"best efforts" shall mean, among other things, that the Company shall submit to
the SEC, within five (5) business days after the Company learns that no review
of a particular Registration Statement will be made by the staff of the SEC or
that the staff has no further comments on the Registration Statement, as the
case may be, a request for acceleration of effectiveness of such Registration
Statement to a time and date not later than 48 hours after the submission of
such request.

        b. Subject to Section 3(r), the Company shall prepare and file with the
SEC such amendments (including post-effective amendments) and supplements to a
Registration Statement and the prospectus used in connection with such
Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the 1933 Act with respect to the
disposition of all Registrable Securities of the Company covered by such
Registration Statement until such time as all of such Registrable Securities
shall have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in such Registration
Statement. In the case of amendments and supplements to a Registration Statement
which are required to be filed pursuant to this Agreement (including pursuant to
this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form
10-Q or Form 8-K or any analogous report under the Securities Exchange Act of
1934, as amended (the "1934 Act"), the Company shall have incorporated such
report by reference into the Registration Statement, if applicable, or shall
file such amendments or supplements with the SEC on the same day on which the
1934 Act report is filed which created the requirement for the Company to amend
or supplement the Registration Statement.

        c. The Company shall (A) permit Legal Counsel to review and comment upon
(i) the Registration Statement at least five (5) days prior to its filing with
the SEC and (ii) all other Registration Statements and all amendments and
supplements to all Registration Statements (except for Annual Reports on Form
10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any
similar or successor reports) within a reasonable number of days prior to their
filing with the SEC, and (B) not file any Registration Statement or amendment or
supplement thereto in a form to which Legal Counsel reasonably objects. The
Company shall not submit a request for acceleration of the effectiveness of a
Registration Statement or any amendment or supplement thereto without the prior
approval of Legal Counsel, which consent shall not be unreasonably withheld. The
Company shall furnish to Legal Counsel, without charge, (i) any correspondence
from the SEC or the staff of the SEC to the Company or its representatives
relating to any Registration Statement, (ii) promptly after the same is prepared
and filed with the SEC, one copy of any Registration Statement
<PAGE>

                                                                          PAGE 6

and any amendment(s) thereto, including financial statements and schedules, all
documents incorporated therein by reference and all exhibits and (iii) upon the
effectiveness of any Registration Statement, one copy of the prospectus included
in such Registration Statement and all amendments and supplements thereto. The
Company shall reasonably cooperate with Legal Counsel in performing the
Company's obligations pursuant to this Section 3.

        d. The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge,
(i) promptly after the same is prepared and filed with the SEC, at least one
copy of such Registration Statement and any amendment(s) thereto, including
financial statements and schedules, all documents incorporated therein by
reference, all exhibits and each preliminary prospectus, (ii) upon the
effectiveness of any Registration Statement, ten (10) copies of the prospectus
included in such Registration Statement and all amendments and supplements
thereto (or such other number of copies as such Investor may reasonably request)
and (iii) such other documents, including copies of any preliminary or final
prospectus, as such Investor may reasonably request from time to time in order
to facilitate the disposition of the Registrable Securities owned by such
Investor.

        e. Subject to Section 3(r), the Company shall use its reasonable best
efforts to (i) register and qualify, unless an exemption from registration and
qualification applies, the resale by Investors of the Registrable Securities
covered by a Registration Statement under such other securities or "blue sky"
laws of all the jurisdictions in the United States, (ii) prepare and file in
those jurisdictions, such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to (x) qualify to do business in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(e), (y) subject itself
to general taxation in any such jurisdiction, or (z) file a general consent to
service of process in any such jurisdiction. The Company shall promptly notify
Legal Counsel and each Investor who holds Registrable Securities of the receipt
by the Company of any notification with respect to the suspension of the
registration or qualification of any of the Registrable Securities for sale
under the securities or "blue sky" laws of any jurisdiction in the United States
or its receipt of actual notice of the initiation or threatening of any
proceeding for such purpose.

        f. The Company shall notify Legal Counsel and each Investor in writing
of the happening of any event, as promptly as practicable after becoming aware
of such event, as a result of which the prospectus included in a Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading (provided that in no event shall such notice contain any
material, nonpublic information), and, subject to Section 3(r), promptly prepare
a supplement or amendment to such Registration Statement to correct such untrue
statement or omission, and deliver ten (10) copies of
<PAGE>

                                                                          PAGE 7

such supplement or amendment to Legal Counsel and each Investor (or such other
number of copies as Legal Counsel or such Investor may reasonably request). The
Company shall also promptly notify Legal Counsel and each Investor in writing
(i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and when a Registration Statement or any post-effective
amendment has become effective (notification of such effectiveness shall be
delivered to Legal Counsel and each Investor by facsimile on the same day of
such effectiveness and by overnight mail), (ii) of any request by the SEC for
amendments or supplements to a Registration Statement or related prospectus or
related information, and (iii) of the Company's reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate.

        g. Subject to Section 3(r), the Company shall use its reasonable best
efforts to prevent the issuance of any stop order or other suspension of
effectiveness of a Registration Statement, or the suspension of the
qualification of any of the Registrable Securities for sale in any jurisdiction
and, if such an order or suspension is issued, to obtain the withdrawal of such
order or suspension at the earliest possible moment and to notify Legal Counsel
and each Investor who holds Registrable Securities being sold of the issuance of
such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

        h. At the reasonable request of any Investor, the Company shall furnish
to such Investor, on the date of the effectiveness of the Registration Statement
and thereafter from time to time on such dates as an Investor may reasonably
request (i) a letter, dated such date, from the Company's independent certified
public accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the Investors, and (ii) an opinion, dated as of such date, of
counsel representing the Company for purposes of such Registration Statement, in
form, scope and substance as is customarily given in an underwritten public
offering, addressed to the Investors.

        i. The Company shall make available for inspection by (i) any Investor,
(ii) Legal Counsel and (iii) one firm of accountants or other agents retained by
the Investors (collectively, the "Inspectors"), all pertinent financial and
other records, and pertinent corporate documents and properties of the Company
(collectively, the "Records"), as shall be reasonably deemed necessary by each
Inspector, and cause the Company's officers, directors and employees to supply
all information which any Inspector may reasonably request; provided, however,
that each Inspector shall agree to hold in strict confidence and shall not make
any disclosure (except to an Investor) or use of any Record or other information
which the Company determines in good faith to be confidential, and of which
determination the Inspectors are so notified, unless (a) the disclosure of such
Records is necessary to avoid or correct a misstatement or omission in any
Registration Statement or is otherwise required under the 1933 Act, (b) the
release of such Records is ordered pursuant to a final, non-appealable subpoena
or order from a court or government body of competent jurisdiction, or (c) the
information in such Records has been made generally available to the public
other than by disclosure in violation of this or any other agreement of which
the Inspector has knowledge. Each Investor agrees that it shall, upon learning
that disclosure of such Records is sought in or by a court or governmental body
of competent jurisdiction or through other means, give prompt notice to the
Company and allow the Company, at its expense, to undertake appropriate action
to prevent
<PAGE>

                                                                          PAGE 8

disclosure of, or to obtain a protective order for, the Records deemed
confidential.

        j. The Company shall hold in confidence and not make any disclosure of
information concerning an Investor provided to the Company unless (i) disclosure
of such information is necessary to comply with federal or state securities
laws, (ii) the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (iii) the release of
such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

        k. The Company shall use its reasonable best efforts either to (i) cause
all the Registrable Securities covered by a Registration Statement to be listed
on each securities exchange on which securities of the same class or series
issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities covered
by the Registration Statement on the Nasdaq National Market, or (iii) if,
despite the Company's reasonable best efforts to satisfy the preceding clause
(i) or (ii), the Company is unsuccessful in satisfying the preceding clause
(i) or (ii), to secure the inclusion for quotation on The Nasdaq SmallCap Market
for such Registrable Securities and, without limiting the generality of the
foregoing, to use its reasonable best efforts to arrange for at least two market
makers to register with the National Association of Securities Dealers, Inc.
("NASD") as such with respect to such Registrable Securities. The Company shall
pay all fees and expenses in connection with satisfying its obligation under
this Section 3(k).

        l. The Company shall cooperate with the Investors who hold Registrable
Securities being offered and, to the extent applicable, facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legend)
representing the Registrable Securities to be offered pursuant to a Registration
Statement and enable such certificates to be in such denominations or amounts,
as the case may be, as the Investors may reasonably request and registered in
such names as the Investors may request.

        m. If requested by an Investor, the Company shall (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as an Investor reasonably requests to be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being offered or sold, the purchase price being paid therefor and any
other terms of the offering of the Registrable Securities to be sold in such
offering; (ii) as soon as practicable make all required filings of such
prospectus supplement or post-effective amendment after being notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) as soon as practicable, supplement or make amendments to
any Registration Statement if reasonably
<PAGE>

                                                                          PAGE 9


requested by an Investor of such Registrable Securities.

        n. The Company shall use its reasonable best efforts to cause the
Registrable Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to consummate the disposition of such Registrable Securities.

        o. The Company shall make generally available to its security holders as
soon as practical, but not later than 90 days after the close of the period
covered thereby, an earnings statement (in form complying with the provisions of
Rule 158 under the 1933 Act) covering a twelve-month period beginning not later
than the first day of the Company's fiscal quarter next following the effective
date of the Registration Statement.

        p. The Company shall otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC in connection with any registration
hereunder.

        q. Within two (2) business days after a Registration Statement which
covers Registrable Securities is ordered effective by the SEC, the Company shall
deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Investors
whose Registrable Securities are included in such Registration Statement)
confirmation that such Registration Statement has been declared effective by the
SEC in the form attached hereto as Exhibit A.
                                   ---------

        r. Notwithstanding anything to the contrary herein, at any time after
the Registration Statement has been declared effective by the SEC, the Company
may delay the disclosure of material non-public information concerning the
Company the disclosure of which at the time is not, in the good faith opinion of
the Board of Directors of the Company and its counsel, in the best interest of
the Company and, in the opinion of counsel to the Company, otherwise required (a
"Grace Period"); provided, that the Company shall promptly (i) notify the
Investors in writing of the existence of material non-public information giving
rise to a Grace Period (provided that in each notice the Company will not
disclose the content of such material non-public information to the Investors)
and the date on which the Grace Period will begin, and (ii) notify the Investors
in writing of the date on which the Grace Period ends; and, provided further,
that no Grace Period shall exceed 15 consecutive days and during any 365 day
period such Grace Periods shall not exceed an aggregate of 30 days and the first
day of any Grace Period must be at least two trading days after the last day of
any prior Grace Period (an "Allowable Grace Period"); provided, however, that
such 15 and 30 day periods shall be extended to 30 and 90 days, respectively, in
the event that such Grace Period is pursuant to an acquisition by the Company
which is required to be reported under Item 2 of Form 8-K and for which pro
forma financial information is required to be reported pursuant to Regulation

Grace Period above, the Grace Period shall begin on and include the date the
holders receive the notice referred to in clause (i) and shall end on and

<PAGE>

                                                                         PAGE 10

the Grace Period, the Company shall again be bound by the first sentence of
Section 3(f) with respect to the information giving rise thereto unless such
material non-public information is no longer applicable.

     4. OBLIGATIONS OF THE INVESTORS.
        ----------------------------

        a. At least seven (7) business days prior to the first anticipated
filing date of a Registration Statement, the Company shall notify each Investor
in writing of the information the Company requires from each such Investor if
such Investor elects to have any of such Investor's Registrable Securities
included in such Registration Statement. It shall be a condition precedent to
the obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities of a particular Investor
that such Investor shall furnish to the Company such information regarding
itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably
required to effect the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request.

        b. Each Investor, by such Investor's acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from such Registration Statement.

        c. Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(g) or
the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(g) or the
first sentence of 3(f) or receipt of notice that no supplement or amendment is
required. Notwithstanding anything to the contrary, the Company shall cause its
transfer agent to deliver unlegended shares of Common Stock to a transferee of
an Investor in accordance with the terms of the Securities Purchase Agreement in
connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(g) or the first sentence of 3(f) and for which the Investor has not
yet settled.

     5. EXPENSES OF REGISTRATION.
        ------------------------

     All reasonable expenses, other than underwriting discounts and commissions,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including, without limitation, all registration, listing and
qualifications fees, printers and accounting fees, and fees and disbursements of
counsel for the Company shall be paid by the Company. The Company shall also
reimburse the Investors for the fees and disbursements of Legal Counsel in
connection with registration, filing or qualification pursuant to Sections 2 and
3 of this Agreement which amount shall
<PAGE>

                                                                         PAGE 11

be limited to $10,000.


     6. INDEMNIFICATION.
        ---------------

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

        a. To the fullest extent permitted by law, the Company will, and hereby
does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the 1933 Act or the 1934
Act (each, an "Indemnified Person"), against any losses, claims, damages,
liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys'
fees, amounts paid in settlement or expenses, joint or several, (collectively,
"Claims") incurred in investigating, preparing or defending any action, claim,
suit, inquiry, proceeding, investigation or appeal taken from the foregoing by
or before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("Blue Sky Filing"), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, (ii) any untrue statement or alleged untrue statement of
a material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading, (iii) any violation or alleged violation by the Company of
the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable Securities pursuant to a Registration Statement or
(iv) any material violation of this Agreement (the matters in the foregoing
clauses (i) through (iv) being, collectively, "Violations"). Subject to Section
6(c), the Company shall reimburse the Indemnified Persons, promptly as such
expenses are incurred and are due and payable, for any legal fees or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(a): (i) shall
not apply to a Claim by an Indemnified Person arising out of or based upon a
Violation which occurs in reliance upon and in conformity with information
furnished in writing to the Company by such Indemnified Person for such
Indemnified Person expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto, if
such prospectus was timely made available by the Company pursuant to Section
3(d); (ii) with respect to any preliminary prospectus, shall not inure to the
benefit of any such person from whom the person asserting any such Claim
purchased the Registrable Securities that are the subject thereof (or to the
<PAGE>

                                                                         PAGE 12

benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected
in the prospectus, as then amended or supplemented, if such prospectus was
timely made available by the Company pursuant to Section 3(d), and the
Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a violation and such Indemnified
Person, notwithstanding such advice, used it or failed to deliver the correct
prospectus as required by the 1933 Act and such correct prospectus was timely
made available pursuant to Section 3(d); (iii) shall not be available to the
extent such Claim is based on a failure of the Investor to deliver or to cause
to be delivered the prospectus made available by the Company, including a
corrected prospectus, if such prospectus or corrected prospectus was timely made
available by the Company pursuant to Section 3(d); and (iv) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Company, which consent shall not be
unreasonably withheld. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Indemnified Person
and shall survive the transfer of the Registrable Securities by the Investors
pursuant to Section 9.

        b. In connection with any Registration Statement in which an Investor is
participating, each such Investor agrees to severally and not jointly indemnify,
hold harmless and defend, to the same extent and in the same manner as is set
forth in Section 6(a), the Company, each of its directors, each of its officers
who signs the Registration Statement each Person, if any, who controls the
Company within the meaning of the 1933 Act or the 1934 Act (each an "Indemnified
Party"), against any Claim or Indemnified Damages to which any of them may
become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such
Claim or Indemnified Damages arise out of or are based upon any Violation, in
each case to the extent, and only to the extent, that such Violation occurs in
reliance upon and in conformity with written information furnished to the
Company by such Investor expressly for use in connection with such Registration
Statement; and, subject to Section 6(c), such Investor will reimburse any legal
or other expenses reasonably incurred by an Indemnified Party in connection with
investigating or defending any such Claim; provided, however, that the indemnity
agreement contained in this Section 6(b) and the agreement with respect to
contribution contained in Section 7 shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of such Investor, which consent shall not be unreasonably withheld;
provided, further, however, that the Investor shall be liable under this Section
6(b) for only that amount of a Claim or Indemnified Damages as does not exceed
the net proceeds to such Investor as a result of the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Indemnified Party and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9. Notwithstanding anything to
the contrary contained herein, the indemnification agreement contained in this
Section 6(b) with respect to any preliminary prospectus shall not inure to the
benefit of any Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary prospectus was corrected on a timely basis in
the prospectus, as then amended or supplemented.

        c. Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section 6 of notice of the commencement of any action or proceeding
(including any governmental action or proceeding) involving a Claim, such
Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is
to be made against any indemnifying party under this Section 6, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying
<PAGE>

                                                                         PAGE 13

party would be inappropriate due to actual or potential differing interests
between such Indemnified Person or Indemnified Party and any other party
represented by such counsel in such proceeding. In the case of an Indemnified
Person, legal counsel referred to in the immediately preceding sentence shall be
selected by the Investors holding at least two- thirds (2/3) in interest of the
Registrable Securities included in the Registration Statement to which the Claim
relates. The Indemnified Party or Indemnified Person shall cooperate fully with
the indemnifying party in connection with any negotiation or defense of any such
action or Claim by the indemnifying party and shall furnish to the indemnifying
party all information reasonably available to the Indemnified Party or
Indemnified Person which relates to such action or Claim. The indemnifying party
shall keep the Indemnified Party or Indemnified Person fully apprized at all
times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its prior written consent,
provided, however, that the indemnifying party shall not unreasonably withhold,
delay or condition its consent. No indemnifying party shall, without the prior
written consent of the Indemnified Party or Indemnified Person, consent to entry
of any judgment or enter into any settlement or other compromise which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability
in respect to such Claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

        d. The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

        e. The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

     7. CONTRIBUTION.
        ------------

     To the extent any indemnification by an indemnifying party is prohibited or
limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section
6 to the fullest extent permitted by law; provided, however, that: (i) no person
involved in the sale of Registrable Securities which person is guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) in connection with such sale shall be entitled to contribution from any
person involved in such sale of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such
<PAGE>

                                                                         PAGE 14

seller from the sale of such Registrable Securities pursuant to such
Registration Statement.

     8. REPORTS UNDER THE 1934 ACT.
        --------------------------

     With a view to making available to the Investors the benefits of Rule 144
promulgated under the 1933 Act or any other similar rule or regulation of the
SEC that may at any time permit the Investors to sell securities of the Company
to the public without registration ("Rule 144"), the Company agrees to:

        a. make and keep public information available, as those terms are
understood and defined in Rule 144;

        b. file with the SEC in a timely manner all reports and other documents
required of the Company under the 1933 Act and the 1934 Act so long as the
Company remains subject to such requirements (it being understood that nothing
herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

        c. furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company, if
true, that it has complied with the reporting requirements of Rule 144, the 1933
Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company, and
(iii) such other information as may be reasonably requested to permit the
investors to sell such securities pursuant to Rule 144 without registration.

     9. ASSIGNMENT OF REGISTRATION RIGHTS.
        ---------------------------------

     The rights under this Agreement shall be automatically assignable by the
Investors to any transferee of Registrable Securities having a value of at least
$5,000,000 if: (i) the Investor agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the
Company within ten (10) days after such assignment; (ii) the Company is, within
ten (10) days after such transfer or assignment, furnished with written notice
of (a) the name and address of such transferee or assignee, and (b) the
securities with respect to which such registration rights are being transferred
or assigned; (iii) immediately following such transfer or assignment the further
disposition of such securities by the transferee or assignee is restricted under
the 1933 Act and applicable state securities laws; (iv) at or before the time
the Company receives the written notice contemplated by clause (ii) of this
sentence the transferee or assignee agrees in writing with the Company to be
bound by all of the provisions contained herein; and (v) such transfer shall
have been made in accordance with the applicable requirements of the Securities
Purchase Agreement.

     10. AMENDMENT OF REGISTRATION RIGHTS.
         --------------------------------

     Provisions of this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively
<PAGE>

                                                                         PAGE 15


or prospectively), only with the written consent of the Company and Investors
who then hold at least two-thirds (2/3) of the Registrable Securities. Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company. No such amendment shall be effective to the
extent that it applies to less than all of the holders of the Registrable
Securities. No consideration shall be offered or paid to any Person to amend or
consent to a waiver or modification of any provision of any of this Agreement
unless the same consideration also is offered to all of the parties to this
Agreement.

    11. MISCELLANEOUS.
        -------------

        a. A Person is deemed to be a holder of Registrable Securities whenever
such Person owns or is deemed to own of record such Registrable Securities. If
the Company receives conflicting instructions, notices or elections from two or
more Persons with respect to the same Registrable Securities, the Company shall
act upon the basis of instructions, notice or election received from the
registered owner of such Registrable Securities.

        b. Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Agreement must be in writing and

jurisdiction, such invalidity or unenforceability shall not affect the validity
or enforceability of the remainder of this Agreement in that jurisdiction or the

                         FORM OF NOTICE OF EFFECTIVENESS

[TRANSFER AGENT]
Attn:

     Re: MicroStrategy, Incorporated

Ladies and Gentlemen:

     We are counsel to MicroStrategy, Incorporated, a Delaware corporation (the
"Company"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "Purchase Agreement") entered into by and
among the Company and the buyers named therein (collectively, the "Holders")
pursuant to which the Company issued to the Holders shares of its Series A
Convertible Preferred Stock, par value $0.001 per share, (the "Preferred
Shares") convertible into shares of the Company's Class A common stock, par
value $0.001 per share (the "Common Stock"). Pursuant to the Purchase Agreement,
the Company also has entered into a Registration Rights Agreement with the
Holders (the "Registration Rights Agreement") pursuant to which the Company
agreed, among other things, to register the Registrable Securities (as defined
in the Registration Rights Agreement), including the shares of Common Stock
issuable upon conversion of the Preferred Shares, under the Securities Act of
1933, as amended (the "1933 Act"). In connection with the Company's obligations
under the Registration Rights Agreement, on ____________ ___, 2000, the Company
filed a Registration Statement on Form S-3 (File No. 333-_____________) (the
"Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Holders as
a selling stockholder thereunder.

     In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                                     Very truly yours,

                                                     [ISSUER'S COUNSEL]

                                                     By:_____________________
