     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 the Series B 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 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

                                       4
<PAGE>

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 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

     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 the Series B
Certificate 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).
                         -------------

          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 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 Series A Redemption Shares. The
execution and delivery of the Transaction Documents by the Company and the

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

                                       6

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. The Series B Certificate of Designations has
been filed prior to the Closing Date with the Secretary of State of the State of

in accordance with its terms and shall not have been amended unless in

debt securities issued by the Company; (C) except as set forth in the third

convertible into or exercisable or exchangeable for Common Stock and the
material rights of the holders thereof in respect thereto except for stock

outstanding shares for purposes of determining what percentage of the Company's
outstanding shares may be issued without violating the Nasdaq 19.99% Rule.

          d.   Issuance of Securities. As of the Closing, the Common Shares and

Shares) will not (i) result in a violation of the Certificate of Incorporation
or the By-laws; (ii) except as disclosed in Schedule 3(e), conflict with, or

would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, any material agreement, indenture or
instrument to which the Company or any of its Subsidiaries is a party; (iii)

in violation of any term of or in default under any contract, agreement,
mortgage, indebtedness, indenture, instrument, judgment, decree or order or any
statute, rule or regulation applicable to the Company or its Subsidiaries,

or in the aggregate, in a Material Adverse Effect. The business of the Company
and its Subsidiaries is not being conducted, and shall not be conducted, in
violation of any law, ordinance or regulation of any governmental entity, except
where such violations would not result, either individually or in the aggregate,
in a Material Adverse Effect. Except as specifically contemplated by this
Agreement, as

interim statements, to the extent they may exclude footnotes or may be 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 Investor 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 were made, not
misleading. As of the date hereof, the Company meets the requirements for use of
Form S-3 for registration of the resale of Registrable Securities (as defined in

which the Company is a party or by which the Company is bound which has not been
previously filed as an exhibit to its reports filed with the SEC under the 1934

necessary to at all times have authorized, and reserved for the purpose of

          e.   Listing. The Company shall promptly secure the listing of all of
               -------
the Registrable Securities (as defined in the Amended and Restated Registration
Rights Agreement) upon each national securities exchange and automated quotation

official notice of issuance) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all Registrable Securities from
time to time issuable under the terms of the Transaction Documents and the
Series B Certificate of Designations. The Company shall use its best efforts to
maintain the Common Stock's authorization for quotation on the Nasdaq National

obligations under this Section 4(e).

          f.   Disclosure of Transactions and Other Material Information. Before
               ---------------------------------------------------------
9:00 a.m. (Eastern Time) on June 18, 2001, the Company shall file a Current
Report on Form 8-K (the "Announcing Form 8-K") with the SEC describing the terms
of the transactions contemplated by the Transaction Documents and by documents
relating to the issuance on the Closing Date of securities to other holders of

such later date as the Company and each Investor agree in writing), a Current
Report on Form 8-K with the SEC disclosing that the Closing did not occur. From
and after the filing of the Announcing Form 8-K with the SEC, the Investor shall
not be in possession of any material nonpublic information received from the
Company, any of its Subsidiaries or any of its respective officers, directors,
employees or agents, that is not disclosed in the Announcing Form 8-K. The
Company shall not, and shall cause each of its Subsidiaries and its and each of
their respective officers, directors, employees and agents not to, provide the
Investor with any material nonpublic information regarding the Company or any of
its Subsidiaries from and after the filing of the Announcing Form 8-K with the

<PAGE>

Subsidiaries, or any of its or their respective officers, directors, employees
and agents, and if the Company has not publicly disclosed the material nonpublic
information within 12 hours of written notice of the breach from the Investor,
in addition to any other remedy provided herein or in the Transaction Documents,
the Investor shall have the right to make a public disclosure, in the form of a
press release, public advertisement or otherwise, of such material nonpublic
information without the prior approval by the Company, its Subsidiaries, or any
of its or their respective officers, directors, employees or agents. The
Investor shall not have any liability to the Company, its Subsidiaries, or any
of its or their respective officers, directors, employees, shareholders or
agents for any such disclosure. Subject to the foregoing, neither the Company
nor the Investor shall issue any press releases or any other public statements
with respect to the transactions contemplated hereby or disclosing the name of
the Investor; provided, however, that the Company shall be entitled, without the
prior approval of the Investor, to make any press release or other public
disclosure with respect to such transactions (i) in substantial conformity with
the Announcing Form 8-K and contemporaneously therewith and (ii) as is required
by applicable law and regulations (provided that in the case of clause (i) the
Investor shall be consulted by the Company in connection with any such press
release or other public disclosure prior to its release).

          g.   Proxy Statement. The Company shall provide each stockholder
               ---------------
entitled to vote at the next annual meeting of stockholders of the Company,
which meeting shall occur on or before July 31, 2001 (the "Stockholder Meeting
Deadline"), a proxy statement, which has been previously reviewed by the
Investor and a counsel of its choice, soliciting each such stockholder's
affirmative vote at such annual stockholder meeting for approval of the
Company's issuance of all of the Securities as described in this Agreement in
accordance with applicable law and the rules and regulations of the Principal
Market (such affirmative approval being referred to herein as the "Stockholder
Approval"), and the Company shall use its best efforts to solicit its
stockholders' approval of such issuance of the Securities and to cause the Board
of Directors of the Company to recommend to the stockholders that they approve
such proposal.

          h.   Corporate Existence. So long as the Investor beneficially owns
               -------------------
any Series B Preferred Stock, the Company shall maintain its corporate existence
and shall not sell all or substantially all of the Company's assets, except in
the event of a merger or consolidation or sale of all or substantially all of
the Company's assets, where the surviving or successor entity in such
transaction (i) assumes the Company's obligations hereunder and under the
agreements and instruments entered into in connection herewith and (ii) is a
publicly traded corporation whose common stock is quoted on or listed for
trading on Nasdaq or NYSE.

          i.   Pledge of Securities. The Company acknowledges and agrees that
               --------------------
the Securities may be pledged by the Investor in connection with a bona fide
margin agreement or other loan secured by the Securities. The pledge of
Securities shall not be deemed to be a transfer, sale or assignment of the
Securities hereunder, and when effecting a pledge of Securities the Investor
shall not be required to provide the Company with any notice thereof or
otherwise make any delivery to the Company pursuant to this Agreement, any other
Transaction Document or the Series B Certificate of Designations, including
without limitation, Section 2(a) of this Agreement; provided that the Investor
and its pledgee shall be required to comply with the provisions of Section 2(a)
hereof in order to effect a sale, transfer or assignment of

                                       13
<PAGE>

Securities to such pledgee. The Company hereby agrees to execute and deliver
such documentation as a pledgee of the Securities may reasonably request in
connection with a pledge of the Securities to such pledgee by the Investor.

          j.   Expenses. Subject to Section 9(k) below, at the Closing, the
               --------
Company shall pay a nonaccountable expense allowance of $31,600 to HFTP

immediately available funds in accordance with each such Investor's written wire
instructions.

          k.   Limitation on Net Sales of Common Stock. So long as the Investor
               ---------------------------------------
holds any Preferred Shares, Conversion Shares or Common Shares, the Investor
agrees that after the date which is 13 trading days after June 19, 2001 it will
not enter into, directly or indirectly, any net sales of Common Stock on any
single day (each such day is referred to as a "Limited Sales Day") in excess of
that number of shares of Common Stock equal to the sum of (i) 0.8% of the daily
trading volume for the Common 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 Investor on each of the days during such period;
provided, however, that the restrictions on net sales set forth above shall not
apply (i) on and after the first date on which there has been any Change of
Control (as defined in Section 4(b) of the Series B Certificate of Designations)
or an announcement of any pending, proposed or intended Change of Control, (ii)
on and after the first date on which there has occurred a Triggering Event (as
defined in Section 3(b) of the Series B Certificate of Designations) or an event
that with the passage of time and without being cured would constitute a
Triggering Event, (iii) if the Company is in default under the Series B
Certificate of Designations or, to the extent the Investor then holds Series A
Preferred Shares, the Series A Certificate of Designations for failing to effect
any requested conversion or redemption of any Preferred Shares pursuant to the
Series B Certificate of Designations or Series A Preferred Shares pursuant to
the Series A Certificate of Designations, respectively, (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 Certificate of
Designations), except for the Settlement Notes (as defined in Section 2(f)(i) of
the Series B Certificate of Designations), (v) on and after 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 30th 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(k).

          l.   Company's Right to Redeem Series A Preferred Shares. If the
               ---------------------------------------------------
Closing occurs on or prior to June 14, 2001, then at any time or times during
the period beginning on the Closing Date and ending on and including the date
which is 180 days after the Closing Date, the Company shall have the right, in
its sole discretion, to redeem up to 120 of the Series A Preferred Shares then
held by the Investor

                                       14
<PAGE>

(a "Redemption at Company's Election") for consideration per Series A Preferred
Share equal to the Conversion Amount (as defined in the Series A Certificate of
Designations) as of the applicable Company's Election Redemption Date (as
defined below) (the "Company's Election Redemption Price"). The Company shall
exercise its right to Redemption at Company's Election by providing the Investor
written notice ("Notice of Redemption at Company's Election") at least 15
Business Days prior to the date of consummation of such redemption ("Company's
Election Redemption Date"). The Notice of Redemption at Company's Election shall
indicate (x) the number of the Investor's Series A Preferred Shares the Company
has elected to redeem (the "Company's Election Redemption Shares"), and (y) the
Company's Election Redemption Date, which date shall not be after the date which
is 180 days after the Closing Date. If the Company has exercised its right of
Redemption at Company's Election and the conditions of this Section 4(l) have
been satisfied, then the Company's Election Redemption Shares outstanding on the
Company's Election Redemption Date shall be redeemed as of the Company's
Election Redemption Date by payment by the Company to the Investor of the
Company's Election Redemption Price for the Series A Preferred Shares being
redeemed. If required by Section 2(d)(viii) of the Series A Certificate of
Designations, the Investor shall thereupon surrender certificates representing
the Series A Preferred Shares redeemed to the Company. If the Company fails to
pay the full Company's Election Redemption Price on the Company's Election
Redemption Date for the Company's Election Redemption Shares pursuant to this
Section 4(l), then (A) the Company's Election Redemption Price shall bear
interest at the rate of 1.5% per month (prorated for partial months) until paid
in full, and (B) at any time thereafter and until the Company pays such unpaid
Company's Election Redemption Price in full, the Investor shall have the option
(the "Void Company Redemption Option") to, in lieu of redemption, require the
Company to promptly return to the Investor any or all of such Series A Preferred
Shares that were submitted for redemption by the Investor under this Section
4(l) and for which the Company's Election Redemption Price (together with any
interest thereon) has not been paid, by sending written notice thereof to the
Company via facsimile (the "Void Company Redemption Notice"). Upon the Company's
receipt of such Void Company Redemption Notice, (i) the Notice of Redemption at
Company's Election shall be null and void with respect to the Company's Election
Redemption Shares subject to the Void Company Redemption Notice and the Investor
shall be entitled to all of the rights under the Series A Certificate of
Designations, (ii) the Company shall immediately return the Series A Preferred
Shares subject to the Void Company Redemption Notice and (iii) the Conversion
Price (as defined in the Series A Certificate of Designations) for such Series A
Preferred Shares subject to such Void Company Redemption Notice shall be
adjusted to the lesser of (A) the Conversion Price (as defined in the Series A
Certificate of Designations) as in effect on the date on which the Void Company
Redemption Notice is delivered to the Company and (B) the lowest Weighted
Average Price (as defined in the Series A Certificate of Designations) of the
Common Stock during the period beginning on the date on which the Notice of
Redemption at Company's Election is delivered to the Investor and ending on the
date on which the Void Company Redemption Notice is delivered to the Company.
Notwithstanding the above, but subject to Section 5 of the Series A Certificate
of Designations, the Investor may convert any Series A Preferred Shares
(including Series A Preferred Shares selected for redemption pursuant to this
Section 4(l)) into Common Stock pursuant to Section 2(b) of the Series A
Certificate of Designations at any time on or prior to the date immediately
preceding the Company's Election Redemption Date. If the Company fails to timely
pay any Company's Election Redemption Price in accordance with this Section
4(l), then the

                                       15
<PAGE>

Company shall not be permitted to submit another Notice of Redemption at
Company's Election without the prior written consent of the Investor.

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

          The Company shall issue irrevocable instructions to its transfer agent
in the form attached hereto as Exhibit C (the "Irrevocable Transfer Agent
                               ---------
Instructions"), and any subsequent transfer agent, to issue certificates,
registered in the name of the Investor or its respective nominee(s), for the
Conversion Shares in such amounts as specified from time to time by the 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 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
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 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.

     6.   CONDITIONS TO THE COMPANY'S OBLIGATIONS AT CLOSING.
          --------------------------------------------------

          The obligation of the Company to redeem and exchange the Series A

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

               i.  Except for the Securities Purchase Agreement, the

          Transfer Agent Instructions (as defined in the Securities Purchase
          Agreement), this Agreement, the Series B Certificate of Designations
          and each of the other Transaction Documents supersede all other prior
          oral or written agreements between the Investor, the Company, their

          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

               ----------------------
inure to the benefit of the parties and their respective successors and assigns,

Company is in compliance with Section 4 of the Series B Certificate of
Designations and Section 4(h) of this Agreement. The Investor may assign some or
all of its rights hereunder without the consent of the Company, provided,
however, that the transferee has agreed in writing to be bound by the applicable

and assumption, which consent shall not be unreasonably withheld.
Notwithstanding anything to the contrary contained in the Transaction Documents,
the Investor shall be entitled to pledge the Securities in connection with a

the representations and warranties of the Company and the Investor contained in

Closing. The Investor shall be responsible only for its own representations,
warranties, agreements and covenants hereunder.

          j.   Further Assurances. Each party shall do and perform, or cause to
               ------------------

the other party may reasonably request in order to carry out the intent and

          k.   Termination. In the event that the Closing shall not have
               -----------
occurred with respect to the Investor on or before June 14, 2001 due to the
Company's or the Investor's failure to satisfy the conditions set forth in
Sections 6 and 7 above (and the nonbreaching party's failure to waive 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
business on such date without liability of any party to any other party;

9(k), the Company shall remain obligated to reimburse the nonbreaching Investor
for the expenses described in Section 4(j) above.

be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

holders have been granted at any time under any other agreement or contract and

rights specifically (without posting a bond or other security), to recover
damages by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law.

          o.   Payment Set Aside. To the extent that the Company makes a payment
               -----------------
or payments to the Investor hereunder or pursuant to the Amended and Restated
Registration Rights Agreement or the Series B Certificate of Designations or the
Investor enforces or exercises its rights hereunder or thereunder, and such
payment or payments or the proceeds of such enforcement or exercise or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside, recovered from, disgorged by or are required to be refunded, repaid
or otherwise restored to the Company, a trustee, receiver or any other Person
under any law (including, without limitation, any bankruptcy law, state or
federal law, common law or equitable cause of action), then to the extent of any
such restoration the obligation or part thereof originally intended to be
satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

          set forth in Sections 9(p)(i), 9(p)(ii) and 9(p)(iii) above do not

          Releasing Person or Investor Releasing Person may have under this

          the rights and preferences set forth in the Series A Certificate of
          Designations.

                                 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.
<PAGE>

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

     The Company's compliance with its obligations under the Certificate of
Designations to redeem the Preferred Shares upon a Triggering Event (as defined
in the Certificate of Designations) or a Change of Control (as defined in
Section 4(b) of the Series B 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 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.
