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

          Each Investor represents and warrants with respect to only itself
that:

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

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

          c.   Transfer or Resale. Such Investor understands that except as
               ------------------
provided in the Registration Rights Agreement: (i) the Securities have not been
and are not being registered under the 1933 Act or any state securities laws,
and may not be offered for sale, sold, assigned or transferred unless (A)
subsequently registered thereunder, (B) such Investor shall have delivered to
the Company an opinion of counsel, in a generally 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) such
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. Such 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 such Investor. Such 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 such Investor
or its advisors, if any, or its representatives shall modify, amend or affect
such Investor's right to rely on the Company's representations and warranties
contained in Sections 3 and 9(l)

                                       5
<PAGE>

below. Such Investor understands that its investment in the Securities involves
a high degree of risk. Such 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. Such Investor understands that the certificates or other
               -------
instruments representing the Preferred Shares and, until such time as the sale
of the Common Shares and the Conversion Shares have been registered under the
1933 Act as contemplated by the 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 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.

          f.   Authorization; Enforcement; Validity. This Agreement and the
               ------------------------------------
Registration Rights Agreement have been duly and validly authorized, executed
and delivered on behalf of such Investor and are valid and binding agreements of
such Investor enforceable against such Investor in accordance with their terms,
subject as to enforceability to general principles of equity and to applicable

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

          The Company represents and warrants to each of the Investors 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).
                         -------------

          b.   Authorization; Enforcement; Validity.  The Company has the
               ------------------------------------
requisite corporate power and authority to enter into and perform its
obligations under this Agreement, the 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 1,200 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

                                       7
<PAGE>

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.

is or may become bound to issue additional shares of capital stock of the

<PAGE>

each Investor true and correct copies of the Company's Certificate of
Incorporation, as amended and as in effect on the date hereof (the "Certificate
of Incorporation"), and the Company's By-laws, as amended and as in effect on

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

non-assessable, (ii) free from all taxes, liens and charges with respect to the
issuance thereof and (iii) with respect to the Preferred Shares, entitled to the
rights and preferences set forth in the respective Certificates of Designations.
As of the Closing, at least 125% of that number of shares of Common Stock
issuable upon conversion of all the Preferred Shares outstanding immediately
following the Closing (without regard to any limitations on conversions, but
subject to adjustment pursuant to the Company's covenant set forth in Section
4(d) below) will have been duly authorized and reserved for issuance upon
conversion of the Preferred Shares.  Upon conversion or issuance in accordance
with the applicable Certificates of Designations, the Conversion Shares and the
Dividend Shares, as the case may be, will be validly issued, fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, with the holders being entitled to all rights accorded to a
holder of Common Stock.  The issuance by the Company of the Securities is exempt
from registration under the 1933 Act.

               ------------
Transaction Documents by the Company, the performance by the Company of its
obligations under the Certificates of Designations and the consummation by the
Company of the transactions contemplated hereby and thereby (including, without

with the requirements of the 1934 Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents.  None of the SEC
Documents, as of the date hereof and as they may have been subsequently amended
by filings made by the Company with the SEC prior to the date hereof, contained

required to be stated therein or necessary in order to make the statements

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 Investors which is
not included in the SEC Documents, contains any untrue statement of a material
fact or omits to state any material fact necessary in order to make the
statements therein, in the light of the circumstance under which they are or

Adverse Effect. The Company has not taken any steps, and does not currently
expect to take any steps, to seek protection pursuant to any bankruptcy law nor
does the Company or any of its Subsidiaries have any knowledge or reason to
believe that its creditors intend to initiate involuntary bankruptcy proceedings
or any actual knowledge of any fact which would reasonably lead a creditor to do
so.  Except as disclosed in Schedule 3(g) or as disclosed in the Company's
                            -------------

               -------
the Registrable Securities (as defined in the Registration Rights Agreement)
upon each national securities exchange and automated quotation system, if any,

Designations.  The Company shall use its best efforts to maintain the Common
Stock's authorization for quotation on the Nasdaq National Market ("NASDAQ") or

any action which would be reasonably expected to result in the delisting or
suspension of the Common Stock from the Principal Market.  The Company shall pay
all fees and expenses in connection with satisfying its obligations under this
Section 4(e).

          f.   Disclosure of Transactions and Other Material Information.  On or
               ---------------------------------------------------------
before April 4, 2001 the Company shall file a Current Report on Form 8-K (the

Preferred Stock (the "Other Holder Documents") and including as exhibits to such
Current Report on Form 8-K this Agreement, each of the Certificates of

the event of a breach of the foregoing covenant by the Company, any of its
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 such Investor,
in addition to any other remedy provided herein or in the Transaction Documents,
an 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.  No
Investor shall 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 any
Investor shall issue any press releases or any other public statements with
respect to the transactions contemplated hereby or disclosing the name of any
Investor; provided, however, that the Company shall be entitled, without the
prior approval of any 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) each
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,

Investors and a counsel of their 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 an Investor beneficially owns
               -------------------
any 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 an 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 no Investor effecting a pledge of Securities shall 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 Certificates of Designations, including without limitation,
Section 2(a) of this Agreement; provided that an Investor and its pledgee shall
be required to comply with the provisions of

                                       14
<PAGE>

Section 2(a) hereof in order to effect a sale, transfer or assignment of
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 an Investor.

          j.   Expenses.  Subject to Section 9(k) below, at the Closing, the
               --------
Company shall pay a nonaccountable expense allowance of $36,720 to Fisher
Capital Ltd. (an Investor) or its designee(s) and $17,280 to Wingate Capital
Ltd. (an Investor) or its designee(s), by wire transfer of immediately available
funds in accordance with each such Investor's written wire instructions.

          k.   Limitation on Net Sales of Common Stock. So long as an Investor
               ---------------------------------------
holds any Preferred Shares, Conversion Shares or Common Shares, such Investor
agrees that 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)
the product of (A) the quotient of (x) the number of Series A Preferred Shares
held by such Investor on the date of this Agreement, divided by (y) 6,000,
multiplied by (B) 2.4% 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 such
Investor's "Daily Sales Amount"), plus (ii) the aggregate amount of all such
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 such
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 applicable Certificates 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 any of the Certificates of Designations
for failing to effect any requested conversion or redemption of any Preferred
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
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 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(k).

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

                                       15
<PAGE>

          m.   Supplemental Representation Regarding the Nasdaq 19.99% Rule.  If
               ------------------------------------------------------------
the Company receives written confirmation from NASDAQ that both the Common Stock
and the Company's Class B common stock, par value $0.001 per share, are included
for purposes of the Nasdaq 19.99% Rule, then the Company shall provide to each
Investor a copy of such written confirmation from Nasdaq (provided that such
copy shall not contain any material nonpublic information).

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

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

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

     The obligation of the Company to redeem and exchange the Series A Preferred
Shares (including the issuance of the applicable number of Common Shares and
Preferred Shares to each Investor) at the Closing is subject to the

with the covenants, agreements and conditions required by the Transaction
Documents to be performed, satisfied or complied with by such Investor at or

          e.   The Company shall have obtained the consent of Foothill Capital

(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
any other certificate, instrument or document contemplated hereby or thereby,
(b) any breach of any covenant, agreement or obligation of the Company contained
in the Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby, (c) any cause of action, suit or claim brought
or made against such Indemnitee (other than a cause of action, suit or claim
which is (x) brought or made by the Company and (y) is not a shareholder

delivery, performance or enforcement of the Transaction Documents or any other

status of such Investor or holder of the Securities as an investor in the
Company.  To the extent that the foregoing undertaking by the Company may be

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

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

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

          e.   Entire Agreement; Effect on Prior Agreements; Amendments.
               --------------------------------------------------------

               i.   Except for the Securities Purchase Agreement, the
     Registration Rights Agreement dated as of June 17, 2000 by and among the
     Company, the Investors 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, among the Company and each
     of the Investors, 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 each 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 any
     Investor makes any representation, warranty, covenant or undertaking with
     respect to such matters.

               ii.  If the Closing occurs on or prior to June 4, 2001 (or such
     later date as the Company and each Investor agree in writing), then
     effective as of the Closing, each Investor, severally and not jointly,
     permanently waives

                                       21
<PAGE>

     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 4, 2001 (or such later
     date as the Company and each Investor agree in writing), then effective as
     of the Closing, each Investor, severally and not joint, permanently waives
     the Company's compliance with its obligations under the Series A
     Registration Rights Agreement, except for Sections 5, 6 and 7 of the Series
     A Registration Rights Agreement. If the Closing occurs on or prior to June
     4, 2001 (or such later date as the Company and each Investor agree in
     writing), then effective as of the Closing, the Company permanently waives
     each 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 Investors holding at least two-thirds (2/3) of the Series A
     Preferred Shares then outstanding.  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.

4(b) of the Series B Certificate of Designations) with respect to which the
Company is in compliance with Section 4 of each of the Certificates of

          h.   No Third Party Beneficiaries.  This Agreement is intended for the
               ----------------------------
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

          i.   Survival.  Unless this Agreement is terminated under Section
               --------
9(k), the representations and warranties of the Company and the Investors
contained in Sections 2 and 3, the agreements and covenants set forth in
Sections 4, 5 and 9, and the indemnification provisions set forth in Section 8,
shall survive the Closing.  Each 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
               ------------------
be done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

          k.   Termination.  In the event that the Closing shall not have
               -----------
occurred with respect to an Investor on or before June 4, 2001 due to the
Company's or such 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;
provided, however, that if this Agreement is terminated pursuant to this Section
9(k), the Company shall remain obligated to reimburse any nonbreaching Investor
for the expenses described in Section 4(j) above.

          l.   Placement Agent.  The Company acknowledges that it has not
               ---------------
engaged a placement agent in connection with the transactions contemplated by
this Agreement; however, the Company has engaged Friedman, Billings & Ramsey,
Inc. as a financial advisor in connection with the transactions contemplated by
this Agreement.  The Company shall be responsible for the payment of any
placement agent's fees, financial advisory fees, or brokers' commissions
relating to or arising out of the transactions contemplated hereby.  The Company
shall pay, and hold each Buyer harmless against, any liability, loss or expense
(including, without limitation, attorney's fees and out-of-pocket expenses)
arising in connection with any such claim.

          m.   No Strict Construction.  The language used in this Agreement will
               ----------------------
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.

          n.   Remedies.  Each Investor and each holder of the Securities shall

have all rights and remedies set forth in the Transaction Documents and the
Certificates of Designations and all rights and remedies which such holders have
been granted at any time under any other agreement or contract and all of the
rights which such holders have under any law.  Any person

                                       25
<PAGE>

having any rights under any provision of this Agreement shall be entitled to
enforce such 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 any Investor hereunder or pursuant to the Registration
Rights Agreement, any of the Certificates of Designations or the Investors
enforce or exercise their 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.

          p.   Mutual General Release.

     NOW THEREFORE, the Company and the Investor hereby agree as follows:

     1.   REDEMPTION AND EXCHANGE OF SERIES A PREFERRED SHARES.
          ----------------------------------------------------

          a.   Redemption of Series A Preferred Shares.  Subject to satisfaction
               ---------------------------------------
(or waiver) of the conditions set forth in Sections 6 and 7, the Company shall
redeem from the Investor and the Investor shall tender to the Company for
redemption on the Closing Date (as defined below) that number of Fixed Series A
Redemption Shares set forth opposite the Investor's name in Column 3 on the
Schedule of Investor (the "Closing"). The redemption price (the "Fixed
Redemption Price") to be paid by the Company for each Fixed Series A Redemption
Share being redeemed at the Closing shall be $10,000 in cash (such that the
aggregate Fixed Redemption Price for all Fixed Series A Redemption Shares being
redeemed is $4,000,000, as set forth opposite the Investor's name in Column 4 on
the Schedule of Investor). Subject to the satisfaction (or waiver) of the
conditions set forth in Sections 6 and 7, at the option of the Company, the
Company may redeem from the Investor and the Investor shall tender to the
Company for redemption on the Closing Date that number of Additional Series A
Redemption Shares set forth opposite the Investor's name in Column 5 on the
Schedule of Investor; provided that the Company has delivered written notice
(the "Notice of Additional Redemption") to the Investor at least 10 days prior
to the Closing Date of its irrevocable election to redeem the Additional Series
A Redemption Shares at the Closing. The redemption price (the "Additional
Redemption Price") to be paid by the Company for each Additional Series A
Redemption Share being redeemed at the Closing shall be an amount in cash equal
to the Conversion Amount for such Additional Series A Redemption Share as of the
Closing Date. The Fixed Redemption Price and the Additional Redemption Price are
collectively referred to as the "Redemption Price."

          b.   Exchange of Series A Preferred Shares.  Subject to satisfaction
               -------------------------------------
(or waiver) of the conditions set forth in Sections 6 and 7, the Company shall
at the Closing (i) except as provided in Section 1(c), issue to the Investor,
and the Investor agrees to exchange that number of the Investor's Series A
Preferred Shares set forth opposite the Investor's name in Column 6 on the
Schedule of Investor for, that number of Common Shares equal to the sum of (A)
the number of Fixed Common Shares set forth opposite the Investor's name in
Column 7 on the Schedule of Investor, plus (B) the Additional Common Shares (as
defined below); and (ii) issue to the Investor, and the Investor agrees to
exchange that number of the Investor's Series A Preferred Shares set forth
opposite the Investor's name in Column 8 on the Schedule of Investor for, that
number of Series B Preferred Shares set forth opposite the Investor's name in
Column 9 on the Schedule of Investor. The "Additional Common Shares" means the
number of shares of Common Stock determined according to the following formula:

                          (0.07)(64/365)($14,700,000)
                  ------------------------------------------
                    Additional Common Share Dividend Price

where the "Additional Common Share Dividend Price" means the product of (A) 95%
multiplied by (B) the arithmetic average of the Weighted Average Price (as
defined in the Series A Certificate of Designations) of the Common Stock on each
of the five (5) consecutive trading

                                       3
<PAGE>

days beginning on and including the third trading day after the date on which
the Announcing Form 8-K (as defined in Section 4(f)) is filed with the
Securities and Exchange Commission.

          c.   Alternative Issuance of Series D Preferred Stock.  If the
               ------------------------------------------------
Investor has not received from the Company the written representation described
in Section 4(m) on or prior to the Closing Date, then, subject to satisfaction
(or waiver) of the conditions set forth in Sections 6 and 7, the Company shall
at the Closing (in lieu of issuing the full amount of the Common Shares which
would otherwise have been issuable pursuant to Section 1(b)(i)) issue to the
Investor, and the Investor agrees to exchange that number of the Investor's
Series A Preferred Shares set forth opposite the Investor's name in Column 6 on
the Schedule of Investor for, both:

               i.   615,000 Common Shares, and

               ii.  that number of shares of Series D Preferred Stock equal to
               the quotient of (A) the difference of (x) the number of Common
               Shares which would have been issuable pursuant clause (i) of
               Section 1(b) but for the fact that the Investor has not received
               the written representation referred to in Section 4(m), minus (y)
               the number of Common Shares to be issued at the Closing pursuant
               to clause (i) of this Section 1(c), divided by (B) 2,000 (the
               "Series D Preferred Shares").

          d.   Closing Date.  The date and time of the Closing (the "Closing
               ------------
Date") shall be 10:00 a.m. Central Time, on June 4, 2001, subject to
notification of satisfaction (or waiver) of the conditions to the Closing set
forth in Sections 6 and 7 (or such other date as is mutually agreed to by the
Company and the Investor, but in no event later than June 15, 2001). The Closing
shall occur on the Closing Date at the offices of Katten Muchin Zavis, 525 West
Monroe Street, Suite 1600, Chicago, Illinois 60661-3693.

          e.   Form of Payment.  On the Closing Date, (i) the Company (A) shall
               ---------------
pay to the Investor the aggregate Redemption Price for the Series A Preferred
Shares held by the Investor which the Company is redeeming at the Closing, by
wire transfer of immediately available funds in accordance with the Investor's
written wire instructions, and (B) shall issue and deliver to the Investor
certificates representing the Common Shares and Preferred Shares being issued in
exchange for the Investor's Series A Preferred Shares not being redeemed by the
Company or retained by the Investor (in such denominations as the Investor shall
request), and (ii) the Investor shall deliver to the Company stock certificates
(the "Series A Preferred Stock Certificates") representing such number of the
Series A Preferred Shares held by the Investor to be redeemed or exchanged by
the Company at the Closing.

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 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 involves a high degree of risk. The

                                       5
<PAGE>

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 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
               ------------------------------------
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 accordance with their terms,

     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).
                         -------------

          b.   Authorization; Enforcement; Validity.  The Company has the

obligations under this Agreement, the 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 Fixed Series A Redemption Shares and the Additional
Series A Redemption Shares. 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

                                       7

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.

the Company or any of its Subsidiaries is in violation of any term of or in
default under any contract, agreement, mortgage, indebtedness, indenture,

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

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,

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 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 the Investor shall not be required to provide the
Company with any notice of the Investor's effecting a pledge of Securities
thereof or otherwise make any delivery to the Company pursuant to this
Agreement, any other Transaction Document or the Certificates 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
Securities to such pledgee. The Company hereby agrees to execute and deliver
such documentation as a

                                       14
<PAGE>

pledgee of the Securities may reasonably request in connection with a pledge of

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 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 applicable

without being cured would constitute a Triggering Event, (iii) if the Company is
in default under any of the Certificates of Designations for failing to effect
any requested conversion or redemption of any Preferred 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 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 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(k).

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

          m.   Supplemental Representation Regarding the Nasdaq 19.99% Rule. If
               ------------------------------------------------------------
the Company receives written confirmation from NASDAQ that both the Common Stock
and the Company's Class B common stock, par value $0.001 per share, are included
for purposes of the

                                       15
<PAGE>

Nasdaq 19.99% Rule (the "Nasdaq Confirmation"), then the Company shall provide
to the Investor a letter or other written document containing the following
representation:

     Under the Nasdaq 19.99% Rule, both the Common Stock and the Company's Class
     B common stock, par value $0.001 per share, are included when making a
     determination regarding the number of shares of common stock outstanding
     immediately prior to June 19, 2000, or at any other time a determination of
     the number of shares outstanding is made for purposes of the Nasdaq 19.99%
     Rule or determining the Exchange Cap (as defined in Section 12 of the
     Series B Certificate of Designations and in Section 11 of the Series D
     Certificate of Designations).

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

          The Company shall issue irrevocable instructions to its transfer agent
in the form attached hereto as Exhibit D (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 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.

          later date as the Company and the Investor agree in writing) and the
          Company redeems all of the Additional Series A Redemption Shares at
          the Closing in accordance with the terms of this Agreement, 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 4, 2001
          (or such later date as the Company and the Investor agree in writing)
          and the Company redeems all of the Additional Series A Redemption
          Shares at the Closing in accordance with the terms of this Agreement,
          then effective as of the Closing, the Investor permanently waives the
          Company's compliance with its obligations

                                       21
<PAGE>

          under the Series A Registration Rights Agreement, except for Sections
          5, 6 and 7 of the Series A Registration Rights Agreement. If the
          Closing occurs on or prior to June 4, 2001 (or such later date as the
          Company and the Investor agree in writing) and the Company redeems all
          of the Additional Series A Redemption Shares at the Closing in
          accordance with the terms of this Agreement, 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.

          g.   Successors and Assigns.  This Agreement shall be binding upon and
               ----------------------
inure to the benefit of the parties and their respective successors and assigns,
including any purchasers of the Securities.  The Company shall not assign this
Agreement or any rights or obligations hereunder without the prior written
consent of 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), including by merger or
consolidation, except pursuant to a Change of Control (as defined in Section
4(b) of the Series B Certificate of Designations) with respect to which the
Company is in compliance with Section 4 of each of the Certificates 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
provisions of this Agreement and the Company has consented to such assignment
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
bona fide margin account or other loan secured by the Securities.

          h.   No Third Party Beneficiaries.  This Agreement is intended for the
               ----------------------------
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

          i.   Survival.  Unless this Agreement is terminated under Section
               --------
9(k), the representations and warranties of the Company and the Investor
contained in Sections 2 and 3, the agreements and covenants set forth in
Sections 4, 5 and 9, and the indemnification provisions

                                       24
<PAGE>

set forth in Section 8, shall survive the 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
               ------------------
be done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

          k.   Termination.  In the event that the Closing shall not have
               -----------
occurred with respect to the Investor on or before June 4, 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;
provided, however, that if this Agreement is terminated pursuant to this Section
9(k), the Company shall remain obligated to reimburse the nonbreaching Investor
for the expenses described in Section 4(j) above.

          l.   Placement Agent.  The Company acknowledges that it has not
               ---------------
engaged a placement agent in connection with the transactions contemplated by
this Agreement; however, the Company has engaged Friedman, Billings & Ramsey,
Inc. as a financial advisor in connection with the transactions contemplated by
this Agreement.  The Company shall be responsible for the payment of any
placement agent's fees, financial advisory fees, or brokers' commissions
relating to or arising out of the transactions contemplated hereby.  The Company
shall pay, and hold each Buyer harmless against, any liability, loss or expense
(including, without limitation, attorney's fees and out-of-pocket expenses)
arising in connection with any such claim.

          m.   No Strict Construction.  The language used in this Agreement will
               ----------------------
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.

          n.   Remedies.  The Investor and each holder of the Securities shall
               --------
have all rights and remedies set forth in the Transaction Documents and the
Certificates of Designations and all rights and remedies which such holders have
been granted at any time under any other agreement or contract and all of the
rights which such holders have under any law.  Any person having any rights
under any provision of this Agreement shall be entitled to enforce such 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 Registration
Rights Agreement, any of the Certificates of Designations or the Investor
enforces or exercises its rights hereunder or

                                       25
<PAGE>

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.

          p.   Mutual General Release.
               ----------------------

          Investor Releasing Persons had, currently has or then has against (i)
          the Company, (ii) any of the Company's current or former parents,
          shareholders, affiliates, subsidiaries, predecessors or assigns, or

          Registration Rights Agreement and the Series A Certificate of
          Designations (collectively, the "Released Documents") other than
          Investor Claims arising after the Closing.

               ii.  In further consideration of the Investor entering into this
          Agreement, effective as of the date of this Agreement, the Company on
          behalf of itself and, to the extent permitted by law, its heirs,
          executors, administrators, devisees, trustees, partners, directors,
          officers, shareholders, employees, consultants, representatives,
          predecessors, principals, agents, parents, associates, affiliates,
          subsidiaries, attorneys, accountants, successors, successors-in-

          Persons"), hereby waives and releases, to the fullest extent permitted
          by law, but subject to Section 9(p)(iv) below, any and all claims,
          rights and causes of action, whether known or unknown (collectively,
          the "Company Claims"), that any of the Company Releasing Persons had
          or currently has against (i) the Investor, (ii) any of the Investor's
          respective current or former parents, shareholders, affiliates,
          subsidiaries, predecessors or assigns, or (iii) any of the Investor's
          or such other persons' or

                                       26
<PAGE>

          entities' current or former officers, directors, employees, agents,
          principals, investors, signatories, advisors, consultants, spouses,
          heirs, estates, executors, attorneys, auditors and associates and
          members of their immediate families (collectively, the "Investor
          Released Persons"), including, without limitation, any Company Claims
          arising out of or relating to the Released Documents; provided,
          however, that if the Investor breaches its obligations under Section
          4(a), then the release set forth in this Section 9(p)(ii) shall be
          null and void and of no further force or effect.

               iii. In further consideration of the Investor entering into this
          Agreement, effective as of the Closing, the Company on behalf of
          itself and, to the extent permitted by law, the other Company
          Releasing Persons, hereby waives and releases, to the fullest extent
          permitted by law, but subject to Section 9(p)(iv) below, any and all
          Company Claims, that any of the Company Releasing Persons had,
          currently has or then has against any of the Investor Released
          Persons, including, without limitation, any Company Claims arising out
          of or relating to the Released Documents.

          set forth in Sections 9(p)(i), 9(p)(ii) and 9(p)(iii) above do not
          affect any claim which any Company Releasing Person or Investor
          Releasing Person may have under this Agreement, Section 8 or Section
          9(m) of the Securities Purchase Agreement or Sections 5, 6 or 7 of the
          Series A Registration Rights Agreement. For the avoidance of doubt,
          the Company acknowledges and agrees that if any Series A Preferred

          Shares shall continue to have all the rights and preferences set forth
          in the Series A Certificate of Designations.
