         2.       INVESTOR'S REPRESENTATIONS AND WARRANTIES.
                  -----------------------------------------

                  The Investor represents and warrants that:

                  a. Reliance on Exemptions. The Investor understands that the
                     ----------------------
Common 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 the Investor's compliance with, the
representations, warranties, agreements, acknowledgments and understandings of
the Investor set forth herein in order to determine the availability of such
exemptions and the eligibility of the Investor to acquire the Securities.

                  b. No Governmental Review. The 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. The 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) the Investor
shall have delivered to the Company an opinion of counsel, in a generally
acceptable form, to the effect that such Securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to an exemption from
such registration, or (C) the Investor provides the Company with reasonable
assurance that such Securities can be sold, assigned or transferred pursuant to
Rule 144 promulgated under the 1933 Act (or a successor rule thereto) ("Rule
144"); (ii) any sale of the Securities made in reliance on Rule 144 may be made
only in accordance with the terms of Rule 144 and further, if Rule 144 is not
applicable, any resale of the Securities under

                                       4
<PAGE>

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 comply with the terms and conditions of any
exemption thereunder. Notwithstanding the foregoing, the Securities may be
pledged in connection with a bona fide margin account or other loan secured by
the Securities.

                  d. Information. The Investor and its advisors, if any, have
                     -----------
been furnished with all materials relating to the business, finances and
operations of the Company and materials relating to the issuance of the
Securities which have been requested by the Investor. The Investor and its
advisors, if any, have been afforded the opportunity to ask questions of the
Company. Neither such inquiries nor any other due diligence investigations
conducted by the Investor or its advisors, if any, or its representatives shall
modify, amend or affect the Investor's right to rely on the Company's
representations and warranties contained in Sections 3 and 9(l) below. The
Investor understands that its investment in the Securities involves a high
degree of risk. The Investor has sought such accounting, legal and tax advice as
it has considered necessary to make an informed investment decision with respect
to its acquisition of the Securities.

                  e. Legends. The 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 1933 Act as contemplated by the Amended and Restated Registration Rights
Agreement, the stock certificates representing the Common Shares and the
Conversion Shares, except as set forth below, shall bear a restrictive legend in
substantially the following form (and a stop-transfer order may be placed
against transfer of such stock certificates):

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
         SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD,
         TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE
         REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS OR (B) AN OPINION
         OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, IN A GENERALLY
         ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR
         APPLICABLE STATE SECURITIES LAWS OR (II) UNLESS SOLD PURSUANT TO RULE
         144 UNDER SAID ACT. 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

                                       5
<PAGE>

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 the 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.

                  f. Authorization; Enforcement; Validity. This Agreement and
                     ------------------------------------
the Amended and Restated Registration Rights Agreement have been duly and
validly authorized, executed and delivered on behalf of the Investor and are
valid and binding agreements of the Investor enforceable against the Investor in

of equity and to applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation and other similar laws relating to, or affecting generally, the
enforcement of applicable creditors' rights and remedies.

                  g. Residency. The Investor is a resident of that country
                     ---------

         3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.
                  ---------------------------------------------

                  The Company represents and warrants to the Investor that:

                  a. Organization and Qualification. The Company and its
                     ------------------------------
"Subsidiaries" (which for purposes of this Agreement means any entity in which
the Company, directly or indirectly, owns capital stock or holds an equity or
similar interest which ownership entitles the Company to elect a majority of the
board of directors or similar governing body of such entity) are corporations
duly organized and validly existing in good standing under the laws of the
jurisdiction in which they are incorporated, and have the requisite corporate
power and authorization to own their properties and to carry on their business
as now being conducted. Each of the Company and its Subsidiaries is duly
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
herewith, or on the authority or ability of the Company to perform its
obligations under the Transaction Documents (as defined below) or any of the
Certificates of Designations. A complete list of entities in which the Company,
directly or indirectly, owns capital stock or holds an equity or similar
interest is set forth on Schedule 3(a).
                         -------------

<PAGE>

                  b. Authorization; Enforcement; Validity. The Company has the
                     ------------------------------------
requisite corporate power and authority to enter into and perform its
obligations under this Agreement, the Amended and Restated Registration Rights
Agreement, the Certificates of Designations, the Irrevocable Transfer Agent
Instructions (as defined in Section 5) and each of the other agreements entered
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
execution and delivery of the Transaction Documents by the Company and the
execution and filing of each of the Certificates of Designations by the Company
and the consummation by it of the transactions contemplated hereby and thereby,
including without limitation the redemption and exchange of the Series A
Preferred Shares, the issuance of the Common Shares and the Preferred Shares and
the reservation for issuance and the issuance of the Conversion Shares issuable
upon conversion of the Preferred Shares, have been duly authorized by the
Company's Board of Directors and no further consent or authorization is required
by the Company, its Board of Directors or its stockholders (except to the extent
that stockholder approval may be required pursuant to the rules of the Nasdaq
National Market for the issuance of a number of shares of Common Stock greater
than that number of 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 valid and binding obligations of the Company enforceable against the Company
in 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
the Secretary of State of the State of Delaware and will be in full force and
effect, enforceable against the Company in accordance with its terms and shall
not have been amended unless in compliance with its terms.

otherwise make any delivery to the Company pursuant to this Agreement, any other
Transaction Document or the Certificates of Designations, including without

the sum of (i) the product of (A) the quotient of (x) the number of Series A

Stock (as reported by Bloomberg Financial Markets ("Bloomberg")) for that
trading day (such amount, with respect to such Limited Sales Day, is referred to
as the Investor's "Daily Sales Amount"), plus (ii) the aggregate amount of all
the Investor's Daily Sales Amounts during the period beginning on and including
the date immediately following the Closing Date and ending on and including the
date immediately preceding the Limited Sales Day with respect to which this
determination is being made, less the net sales of Common Stock made by the

Shares pursuant to the applicable Certificates of Designations, (iv) on and
after any date on which the Company issues or sells or is deemed to have issued
or sold any securities with a Variable Price (as defined in the Series B

the Stockholder Meeting Deadline, if the Company fails to receive the
Stockholder Approval on or before the Stockholder Meeting Deadline, (vi) on and
after the 30/th/ trading day prior to the date which is three (3) years after
the Closing Date, or (vii) with respect to any sale of Common Stock at a price
equal to or greater than $17.50 (as adjusted for any stock splits, stock
dividends, stock combinations or other similar transactions) and any such sale
shall be ignored for all purposes of this Section 4(j).

                  k. Restrictions on Issuances of Preferred Shares. The Company
                     ---------------------------------------------
shall not issue any shares of Series B Preferred Stock, Series C Preferred Stock
or Series E Preferred Stock to anyone other than the Investor, except on the
Closing Date concurrent with the Closing to holders of the Series A Preferred

such case there no longer exists a Loan Default, then in each such case the
Company shall deliver written notice ("Loan Default Cure Notice") to each
Investor within one (1) Business Day of such Loan Default no longer being in
existence; provided that prior to or current with the Company's delivery of a
Loan Default Cure Notice to an Investor, the Company shall publicly disclose

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 the 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 the 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 the Investor
and without any restrictive legend. The Company acknowledges that a breach by it
of its obligations hereunder will cause irreparable harm to the Investor 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 Investor 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.

                  In consideration of the Investor's execution and delivery of

Investor and each other holder of the Securities and all of their stockholders,
officers, directors, employees and direct or indirect investors and any of the
foregoing persons' agents or other representatives (including, without
limitation, those retained in connection with the transactions contemplated by
this Agreement) (collectively, the "Indemnitees") from and against any and all
actions, causes of action, suits, claims, losses, costs, penalties, fees,
liabilities and damages, and expenses in connection therewith (irrespective of
whether any such Indemnitee is a party to the action for which indemnification
hereunder is sought), and including reasonable attorneys' fees and disbursements
(the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or
arising out of, or relating to (a) any misrepresentation or breach of any
representation or warranty made by the Company in the Transaction Documents or

permissible under applicable law. Except as otherwise set forth herein, the
mechanics and procedures with respect to the rights and obligations under this

limitation, those procedures with respect to the settlement of claims and the
Company's rights to assume the defense of claims.

         9.       MISCELLANEOUS.
                  -------------

                  a. Governing Law; Jurisdiction; Jury Trial. All questions
                     ---------------------------------------
concerning the construction, validity, enforcement and interpretation of this
Agreement shall be governed by the internal laws of the State of New York,
without giving effect to any choice of law or conflict of law provision or rule
(whether of the State of New York or any other jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of New
York. Each party hereby irrevocably submits to the non-exclusive jurisdiction of
the state and federal courts sitting in the City of New York, borough of
Manhattan, for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein, and
hereby irrevocably waives, and agrees not to assert in any suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit,

                                       20
<PAGE>

action or proceeding is brought in an inconvenient forum or that the venue of
such suit, action or proceeding is improper. Each party hereby 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 party at the
address for such notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS
AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

                  b.  Counterparts. This Agreement may be executed in two or
                      ------------
more identical counterparts, all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

                  c.  Headings. The headings of this Agreement are for
                      --------
convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement.

                  d.  Severability. If any provision of this Agreement shall be
                      ------------
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction;
provided, however, that if Section 9(p) shall be invalid or unenforceable in any
jurisdiction, then, notwithstanding that this Agreement otherwise amends and
restates the Original Redemption and Exchange Agreement, Section 9(p) of the
Original Redemption and Exchange Agreement shall remain in full force and
effect.

          Registration Rights Agreement dated as of June 17, 2000 by and among
          the Company, the Investor and the Other Investors (the "Series A
          Registration Rights Agreement"), the Series A Certificate of
          Designations, the Waiver Agreements, each executed as of January 3,
          2001, between the Company and the of the Investor, and the Irrevocable
          Transfer Agent Instructions (as defined in the Securities Purchase
          Agreement), this Agreement, the Certificates of Designations and each
          of the other Transaction Documents supersede all other prior oral or
          written agreements between the Investor, the Company, their affiliates
          and persons acting on their behalf with respect to the matters
          discussed herein, and this Agreement and the instruments referenced
          herein contain the entire understanding of the parties with respect to
          the matters covered herein and therein and, except as specifically set
          forth herein or therein, neither the Company nor the Investor makes
          any representation, warranty, covenant or undertaking with respect to
          such matters.

               ii.  If the Closing occurs on or prior to June 14, 2001 (or such
          later date as the Company and the Investor agree in writing), then
          effective as of the Closing, the Investor permanently waives the
          Company's compliance with its obligations under the Securities
          Purchase Agreement, except for Sections 8 and 9 of the Securities
          Purchase Agreement. If the Closing occurs on or prior to June 14, 2001
          (or such later date as the Company and the Investor agree in writing),

          Company's compliance with its obligations under the Series A

          Investor agree in writing), then effective as of the Closing, the
          Company permanently waives the Investor's compliance with its
          obligations under the Series A Registration Rights Agreement, except
          for Sections 6 and 7 of the Series A Registration Rights Agreement.

               iii. No provision of this Agreement may be amended or waived
          other than by an instrument in writing signed by the Company and the
          holders of at least two-thirds (2/3) of the Common Shares and
          Conversion Shares (assuming conversion of all outstanding Preferred
          Shares without giving effect to any limitations on conversion) or, if
          prior to the Closing Date, the Investor. No such amendment shall be
          effective to the extent that it applies to less than all of the
          holders of the Securities then outstanding. 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 the Transaction Documents or
          the Certificates of Designations unless the same consideration also is
          offered to all of the parties to the Transaction Documents or holders
          of Securities, as the case may be.

                                 -------------
                                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.

     (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.

                                       35
<PAGE>

     (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,

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

                               -----------------

1.   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.

          -----------

          As used in this Agreement, the following terms shall have the
following meanings:

          a.   "Holder" means an Investor, any transferee or assignee thereof to
whom an Investor assigns its rights under this Agreement and who agrees to
become bound by the provisions of this Agreement in accordance with Section 9
and any transferee or assignee thereof to whom a transferee or assignee assigns

partnership, a joint venture, a corporation, a trust, an unincorporated
organization and a governmental or any department or agency thereof.

          c.   "Register," "registered," and "registration" refer to a

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

                                       2

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

          a.   Mandatory Registration. The Company shall prepare, and, on or
               ----------------------
after the tenth (10th) Business Day (as defined in the Amended and Restated
Redemption and Exchange Agreement) following the Closing Date (as defined in the
Amended and Restated Redemption and Exchange 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 sum of (i) the Registrable
Securities relating to the Common Shares, (ii) the product of (w) 1.25 and (x)
the Registrable Securities relating to the Series B Preferred Shares, (iii) the
product of (y) 1.25 and (z) the Registrable Securities relating to the Series C
Preferred Shares, (iv) the Registrable Securities relating to the Series D
Preferred Shares and (v) 1,542,857 shares of Common Stock (which are Registrable
Securities) relating to the Series E Preferred Shares, in each case, as of the
trading day immediately preceding the date the Registration Statement is
initially filed with the SEC (as if the closing of the transactions contemplated
by the Amended and Restated Redemption and Exchange Agreement occurred on such
date), 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 93 days
after the 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 Holders based on the number of Registrable Securities held by
each Holder 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 a Holder sells or otherwise transfers any of such Holder's
Registrable Securities, each transferee shall be allocated a pro rata portion of
the then remaining number of Registrable 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 Holders, pro rata based on the number of
Registrable Securities then held by such Holders which are covered by such
Registration Statement.

          c.   Legal Counsel. Subject to Section 5 hereof, the Investors 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

                                       3
<PAGE>

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 a Holder'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 the sum of
(i) the Registrable Securities relating to the Common Shares, (ii) 125% of the
Registrable Securities relating to the Series B Preferred Shares, (iii) 125% of
the Registrable Securities relating to the Series C Preferred Shares, (iv) the
Registrable Securities relating to the Series D Preferred Shares and (v) 150% of
the Registrable Securities relating to the Series E Preferred Shares (assuming
for purposes of this determination that the Conversion Price (as defined in the
Series E Certificate of Designations) for the Series E Preferred Shares is $3.50
(subject to adjustment for stock splits, stock dividends, stock combinations and
similar transactions after the Closing Date) during the period beginning on the
Closing Date and ending on and including the date which is 180 days after the
Closing Date), in each case, 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 its 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 sum of (x) the number of Registrable Securities relating to Common
Shares covered by such Registration Statement and (y) 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 each respective Certificate of
Designations and, with respect to the Series E Preferred Shares, assuming for
purposes of this determination that the Conversion Price (as defined in the
Series E Certificate of Designations) for the Series E Preferred Shares is $3.50
(subject to adjustment for stock splits, stock dividends, stock combinations and
similar transactions after the Closing Date) during the period beginning on the
Closing Date and ending on and including the date which is 180 days after the
Closing Date).

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

                                       4
<PAGE>

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 Registrable Securities (which
remedy shall not be exclusive of any other remedies available at law or in
equity), the Company shall pay to each holder of Common Shares and/or Preferred
Shares, as the case may be, an amount in cash per Common Share, Conversion Share
and Dividend (excluding each Common Share, Conversion Share and Dividend Share
which may be sold by the holder thereof pursuant to Rule 144(k) under the 1933
Act on the date on which the amounts provided for in this Section 2(f) are
incurred) or Preferred Share (excluding each Preferred Share with respect to
which the holder thereof may sell the shares of Common Stock issuable upon
conversion of such Preferred Share pursuant to Rule 144(k) under the 1933 Act on
the date on which the amounts provided for in this Section 2(f) are incurred),
as the case may be, held equal to the product of (A) $10,000, with respect to a
Preferred Share, or $3.00, with respect to a Common Share, Conversion Share or
Dividend Share (subject to adjustment for stock splits, stock dividends, stock
combinations and other similar transactions), as the case may be, 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. A "Holder 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 Holders 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 Holders for purposes of inclusion in the Registration Statement,
with respect to changes in the plan of distribution or the failure of the
Holders 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:

                                       5
<PAGE>

          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 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 Holders 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 Holders
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,

                                       6
<PAGE>

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 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 Holder 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 Holder may reasonably request) and (iii) such other
documents, including copies of any preliminary or final prospectus, as such
Holder may reasonably request from time to time in order to facilitate the
disposition of the Registrable Securities owned by such Holder.

          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 Holders 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 Holder 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 Holder 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

                                       7
<PAGE>

statement or omission, and deliver ten (10) copies of such supplement or
amendment to Legal Counsel and each Holder (or such other number of copies as
Legal Counsel or such Holder may reasonably request). The Company shall also
promptly notify Legal Counsel and each Holder 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 Holder 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 Holder 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 Holder, the Company shall
furnish to such Holder, on the date of the effectiveness of the Registration
Statement and thereafter from time to time on such dates as a Holder 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 Holders, 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 Holders.

          i.   The Company shall make available for inspection by (i) any
Holder, (ii) Legal Counsel and (iii) one firm of accountants or other agents
retained by the Holders (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 a Holder) 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 Holder 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

                                       8
<PAGE>

the Company and allow the Company, at its expense, to undertake appropriate
action to prevent 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 a Holder 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 a Holder is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt written notice to such Holder
and allow such Holder, at the Holder'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 Holders 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 Holders may reasonably request and registered in such
names as the Holders may request.

          m.   If requested by a Holder, the Company shall (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as a Holder 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 requested by a Holder of such Registrable Securities.

                                       9
<PAGE>

          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 Holders 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 Holders 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 Holders) and the date on which the Grace Period will begin, and (ii) notify
the Holders in writing of the date on which the Grace Period ends; and, provided
further, that no Grace Period shall exceed 30 consecutive days and during any
365 day period such Grace Periods shall not exceed an aggregate of 60 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 30 day period shall be extended to 45 days, and such 60 day
period shall be extended to 90 days, 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 S-X promulgated under the 1933 Act. For
purposes of determining the length of a 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 include the later of the date the holders
receive the notice referred to in clause (ii) and the date referred to in such
notice. The provisions of Section 3(g) hereof shall not be applicable during the
period of any Allowable Grace Period. Upon expiration of 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 HOLDERS.
                  --------------------------

                  a.    At least seven (7) business days prior to the first
anticipated filing date of a Registration Statement, the Company shall notify
each Holder in writing of the information the Company requires from each such
Holder if such Holder elects to have any of such Holder'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 Holder that
such Holder 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 Holder, by such Holder'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 Holder has notified the Company in
writing of such Holder's election to exclude all of such Holder's Registrable
Securities from such Registration Statement.

                  c.    Each Holder 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 Holder will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Holder'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 a
Holder in accordance with the terms of the Amended and Restated Redemption and
Exchange Agreement in connection with any sale of Registrable Securities with
respect to which a Holder has entered into a contract for sale prior to the
Holder'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 Holder 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 Holders 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 be limited to $4,000.

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

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

                                       11
<PAGE>

                  a.    To the fullest extent permitted by law, the Company
will, and hereby does, indemnify, hold harmless and defend each Holder, the
directors, officers, partners, employees, agents, representatives of, and each
Person, if any, who controls any Holder 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 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
Holder to deliver or to cause to be delivered the prospectus made available by
the Company, including a corrected

                                       12
<PAGE>

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 Holders pursuant to Section 9.

                  b.    In connection with any Registration Statement in which a
Holder is participating, each such Holder 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 Holder expressly for use in connection with
such Registration Statement; and, subject to Section 6(c), such Holder 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 Holder, which consent shall not be
unreasonably withheld; provided, further, however, that the Holder 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 Holder 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 Holders 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 party

                                       13
<PAGE>

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 Holders 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 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 Holders 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 Holders 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(b) of
the Amended and Restated Redemption and Exchange Agreement) and the filing of
such reports and other documents is required for the applicable provisions of
Rule 144; and

                  c.    furnish to each Holder so long as such Holder 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 Holders 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 Holders to any transferee of Registrable Securities having a
face value of at least $5,000,000 if: (i) the Holder 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 Amended and Restated Redemption and Exchange 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 or prospectively), only with the written consent of the Company
and Holders 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 Holder

                                       15
<PAGE>

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 will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party); or (iii) one business day after deposit with

addressed to the party to receive the same. The addresses and facsimile numbers
for such communications shall be:

                  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 Amended and Restated Redemption and Exchange Agreement (the "Amended and
Restated Redemption and Exchange Agreement") entered into by and among the
Company and the investors named therein (collectively, the "Holders") pursuant
to which the Company issued to the Holders in exchange for shares of the
Company's Series A Convertible Preferred Stock, par value $0.001 per share, held
by the Holders, shares of the Company's Class A common stock, par value $0.001
per share (the "Common Stock"), shares of the Company's Series B Convertible
Preferred Stock, par value $0.001 per share, convertible into shares of Common
Stock, shares of the Company's Series C Convertible Preferred Stock, par value
$0.001 per share, convertible into shares of Common Stock, shares of the
Company's Series D Convertible Preferred Stock, par value $0.001 per share,
convertible into shares of Common Stock and shares of the Company's Series E
Convertible Preferred Stock, par value $0.001 per share, convertible into shares
of Common Stock. Pursuant to the Amended and Restated Redemption and Exchange
Agreement, the Company also has entered into a Amended and Restated Registration
Rights Agreement with the Holders (the "Amended and Restated Registration Rights
Agreement") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined in the Amended and Restated
Registration Rights Agreement), under the Securities Act of 1933, as amended
(the "1933 Act"). In connection with the Company's obligations under the Amended
and Restated Registration Rights Agreement, on ____________ ___, 2001, 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:
