               ----------------------
Shares, the Preferred Shares, the Conversion Shares and the Dividend Shares (as
defined in each of the Series B Certificate of Designations, the Series C
Certificate of Designations and the Series E Certificate of Designations)
(collectively, the "Securities") are being offered to it in reliance on specific
exemptions from the registration requirements of the United States federal and
state securities laws and that the Company is relying in part upon the truth and
accuracy of, and such Investor's compliance with, the representations,
warranties, agreements, acknowledgments and understandings of such Investor set
forth herein in order to determine the availability of such exemptions and the
eligibility of such Investor to acquire the Securities.

          b.   No Governmental Review. Such Investor understands that no United
               ----------------------
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

          c.   Transfer or Resale. Such Investor understands that except as
               ------------------
provided in the Amended and Restated Registration Rights Agreement: (i) the
Securities have not been and are not being registered under the 1933 Act or any
state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (A) subsequently registered thereunder, (B) such Investor
shall have delivered to the Company an opinion of counsel, in a generally

only in accordance with the terms of Rule 144 and further, if Rule 144 is not
applicable, any resale of the Securities under circumstances in which the seller
(or the person through whom the sale is made) may be deemed to be an underwriter
(as that term is defined in the 1933 Act) may require compliance with some other
exemption under the 1933 Act or the rules and regulations of the SEC thereunder;
and (iii) neither the Company nor any other person is under any obligation to
register the Securities under the 1933 Act or any state securities laws or to

               -----------
furnished with all materials relating to the business, finances and operations

have been afforded the opportunity to ask questions of the Company. Neither such
inquiries nor any other due diligence investigations conducted by such Investor
or its advisors, if any, or its representatives shall modify, amend or affect
such Investor's right to rely on the Company's representations and warranties

Securities.

          e.   Legends. Such Investor understands that the certificates or other
               -------
instruments representing the Preferred Shares and, until such time as the sale
of the Common Shares and the Conversion Shares have been registered under the

Agreement, the stock certificates representing the Common Shares and the
Conversion Shares, except as set forth below, shall bear a restrictive legend in

     NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION
     WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE SECURITIES.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if, unless otherwise required by state securities laws, (i) such
Securities are registered for resale under the 1933 Act, (ii) in connection with
a sale transaction, such holder provides the Company with an opinion of counsel
reasonably satisfactory to the Company, in a generally acceptable form, to the
effect that a public sale, assignment or transfer of the Securities may be made
without registration under the 1933 Act, or (iii) such holder provides the
Company with reasonable assurances (including, if requested by the Company,
delivering such reasonable assurances to the Company's counsel in connection
with such counsel rendering an opinion on the validity of a sale by such
Investor pursuant to Rule 144) that the Securities can be sold pursuant to Rule
144 without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold.

qualified as a foreign corporation to do business and is in good standing in
every jurisdiction in which its ownership of property or the nature of the
business conducted by it makes such qualification necessary, except to the
extent that the failure to be so qualified or be in good standing would not have
a Material Adverse Effect. As used in this Agreement, "Material Adverse Effect"
means any material adverse effect on the business, properties, assets,
operations, results of operations, or financial condition of the Company and its
Subsidiaries, if any, taken as a whole, or on the transactions contemplated
hereby or by the agreements and instruments to be entered into in connection

obligations under the Transaction Documents (as defined below) or any of the
Certificates of Designations. A complete list of entities in which the Company,

into by the parties hereto in connection with the transactions contemplated by
this Agreement (collectively, the "Transaction Documents"), and to issue the
Securities in accordance with the terms hereof and thereof and to redeem the 600
Series A Preferred Shares being redeemed pursuant to this Agreement. The

shares of Common Stock that the Company may issue without breaching the
Company's obligations under the rules or regulations of the Nasdaq National
Market (the "Nasdaq 19.99% Rule")). The Transaction Documents have been duly
executed and delivered by the Company. The Transaction Documents constitute the

accordance with their terms, except as such enforceability may be limited by
general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally, the enforcement of creditors' rights and remedies. Each of
the Certificates of Designations has been filed prior to the Closing Date with

promulgated thereunder applicable to the SEC Documents. None of the SEC
Documents, as of the date hereof and as they may have been subsequently amended
by filings made by the Company with the SEC prior to the date hereof, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements

condensed or summary statements) and fairly present in all material respects the
financial position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Investors which is
not included in the SEC Documents, contains any untrue statement of a material
fact or omits to state any material fact necessary in order to make the
statements therein, in the light of the circumstance under which they are or

believe that its creditors intend to initiate involuntary bankruptcy proceedings
or any actual knowledge of any fact which would reasonably lead a creditor to do
so. Except as disclosed in Schedule 3(g) or as disclosed in the Company's Annual
                           -------------

               --------------------
the Securities may be pledged by an Investor in connection with a bona fide
margin agreement or other loan secured by the Securities. The pledge of

     5.   TRANSFER AGENT INSTRUCTIONS.
          ---------------------------

          The Company shall issue irrevocable instructions to its transfer agent
in the form attached hereto as Exhibit F (the "Irrevocable Transfer Agent
                               ---------
Instructions"), and any subsequent transfer agent, to issue certificates,
registered in the name of each Investor or its respective nominee(s), for the
Conversion Shares in such amounts as specified from time to time by each
Investor to the Company upon conversion of the Preferred Shares. Prior to
registration of the Common Shares and the Conversion Shares under the 1933 Act,
all such certificates shall bear the restrictive legend specified in Section
2(b) of this Agreement. The Company warrants that no instruction other than the
Irrevocable Transfer Agent Instructions referred to in this Section 5 and stop
transfer instructions to give effect to Section 2(b) hereof (in the case of the
Common Shares and the Conversion Shares, prior to registration of the Common
Shares and the Conversion Shares under the 1933 Act) will be given by the
Company to its transfer agent and that the Securities shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement and the Amended and Restated Registration Rights
Agreement. If an Investor provides the Company with an opinion of counsel, in a
generally acceptable form, to the effect that a public sale, assignment or
transfer of Securities may be made without registration under the 1933 Act or
the Investor provides the Company with reasonable assurances (including, if
requested by the Company, delivering such reasonable assurances to the Company's
counsel in connection with such counsel rendering an opinion on the validity of
a sale by such Investor pursuant to Rule 144) that the Securities can be sold
pursuant to Rule 144 without any restriction as to the number of securities
acquired as of a particular date that can then be immediately sold, the Company
shall permit the transfer, and, in the case of the Common Shares and the
Conversion Shares, promptly instruct its transfer agent to issue one or more
certificates in such name and in such denominations as specified by such
Investor and without any restrictive legend. The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to the
Investors by vitiating the intent and purpose of the transaction contemplated
hereby. Accordingly, the Company acknowledges that the remedy at law for a
breach of its obligations under this Section 5 will be inadequate and agrees, in
the event of a breach or threatened breach by the Company of the provisions of
this Section 5, that the Investors shall be entitled, in addition to all other
available remedies, to an order and/or injunction restraining any breach and
requiring immediate issuance and transfer, without the necessity of showing
economic loss and without any bond or other security being required.

irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof to such

unsatisfied condition(s)), the nonbreaching party shall have the option to
terminate this Agreement with respect to such breaching party at the close of

                                 Schedule 3(c)
                                 -------------
                                Capitalization
                                --------------

(A)  None.

(B)  In connection with the Stipulation of Settlement, dated January 11, 2001,
     entered into among the Company and Lead Plaintiffs Akiko Minami, Atsukuni
     Minami and Local 144 Nursing Home Pension Fund relating to the Company's
     class action securities litigation (the "Settlement Agreement"), the
     Company will issue five-year 7 1/2% Senior Unsecured Notes having an
     aggregate principal amount of $80.5 million.

(C)  (1)  Under a Management Services Agreement, dated June 7, 2000,
     MicroStrategy Management Corporation ("MMC"), a wholly-owned subsidiary of
     the Company, has the right to purchase from the Company, in three
     installments, approximately 143,000 shares of Class A Common Stock at a
     purchase price equal to the par value of these shares ($.001 per share)
     over a two year period expiring in September 2002. The specific number of
     shares subject to the purchase right will depend on certain multipliers
     relating to future revenues and employee-attrition rates of MicroStrategy
     Brazil Ltda. Sucursal Argentina ("Argentinean Operations") over the two
     year period and the operation of a collar on the aggregate market value of
     the shares, which shall not exceed $5 million. In exchange for these share
     purchase rights, MMC renders to the Company certain management services
     with respect to the Argentinean Operations. MMC has subcontracted the
     performance of such management services to Claudio Remon, to whom MMC
     delivers the shares purchased from the Company.

     (2)  The Series A Convertible Preferred Stock of the Company is convertible
     into Class A Common Stock at an initial conversion rate equal to the
     average of the daily volume weighted average prices of the Class A Common
     Stock for the 17 trading days following June 19, 2000 ("Closing Date")
     (i.e., $33.3854). The Company, at its option, can require that the
     preferred stock convert into Class A Common Stock on the second anniversary
     of the Closing Date or may extend the term of the Series A Preferred Shares
     for up to an additional two years. The conversion rate may adjust, subject
     to certain limits and conditions, on the first anniversary of the Closing
     Date and, if the Company elects to extend the maturity of the Series A
     Preferred Shares, on each subsequent anniversary. The Series A Preferred
     Shares carry a 7% dividend yield, payable in cash or Class A Common Stock,
     at the Company's option.

     (3)  Each share of Series A Preferred Stock of Strategy.com Incorporated
     ("Strategy.com") is convertible into such number of fully paid and
     nonassessable shares of Class A Common Stock of Strategy.com as is
     determined by dividing $3.19 by the conversion price in effect at the time
     of conversion (currently $3.19 per share), which may be adjusted from time
     to time. Upon the closing of a public offering of Strategy.com's Class A
     Common Stock at a price to the public of at least $10.00 share and
     resulting in at least $30,000,000 of net proceeds to Strategy.com, all
     outstanding shares of Series A Preferred Stock will automatically convert
     into shares of Class A Common Stock.
<PAGE>

     (4)  The Company will issue (i) 2,777,778 shares of Class A Common Stock
     and (ii) warrants to purchase 1,900,000 shares of Class A Common Stock at
     an exercise price of $40 per share, pursuant to the terms of the Settlement
     Agreement.

     (5)  Strategy.com Incorporated has granted options, currently outstanding,
     to purchase 5,203,918 shares of its Class A Common Stock under its 2000
     Stock Option Plan.

(D)  (1)  The terms of the Company's Series A Preferred Stock contain mandatory
     redemption provisions.

     (2)  One of the Company's subsidiaries, Strategy.com Incorporated, has
     issued 16,536,049 shares of its Series A Preferred Stock. These shares are
     mandatorily redeemable for $3.19 per share plus any dividends accrued or
     declared but unpaid thereon at mandatory redemption dates of October 17,
     2005, 2006 and 2007, with the maximum redemption portions at each date
     being 33%, 50% and 100%, respectively.

(E)  The Company has issued a warrant to purchase 50,000 shares of Class A
     Common Stock to Foothill Capital Corporation ("Foothill"), which warrant
     contains anti-dilution provisions.

(F)  None.

                                 Schedule 3(e)
                                 -------------
                                 No Conflicts
                                 ------------

     The Company's compliance with its obligations under the Certificates of
Designations to redeem the Preferred Shares upon a Triggering Event (as defined
in the Certificates of Designations) or a Change of Control (as defined in
Section 4(b) of the Series B Certificate of Designations, Section 4(b) of the
Series C Certificate of Designations or Section 4(b) of the Series E Certificate
of Designations) currently would result in a default under the Company's Amended
and Restated Loan and Security Agreement, dated as of June 14, 2001, with
Foothill Capital Corporation unless the Company were to obtain the consent of
Foothill.

1.   The Company has had capital expenditures of approximately $4.2 million in
     the aggregate since December 31, 2000.

                                 Schedule 3(o)

                               Other Information
                               -----------------

I.   The Company has taken steps to reduce its workforce by approximately 600
     persons and will incur related severance and restructuring charges. On May
     4, 2001, the Strategy.com Board approved a further restructuring which will
     reduce the operations of the Strategy.com down to approximately 35
     employees by early July. These remaining employees will be utilized for,
     among other things, the carrying out of Strategy.com's existing contracts.
     Strategy.com is currently analyzing the impact that the various actions
     taken as part of the restructuring will have on its results of operations
     for Q2 and the remainder of 2001. The Company anticipates that severance
     and certain other termination benefit payments associated with the April
     and May restructuring plans will be accrued and classified as
     restructuring. Additionally, certain other costs associated with the
     restructuring are expected to be included in the restructuring charge,
     including costs associated with exiting and consolidating certain office
     space, a provision for idle computers, software, printers, copiers, and/or
     telecommunications equipment (cell phones, office phones, wireless
     equipment, etc.), as well as professional fees and certain other costs.

2.   The Company's earnings for the first quarter of 2001 were below consensus
     estimates, as disclosed in the Company's Quarterly Report on Form 10-Q for
     the Three Months ended March 31, 2001.
