Company's Class A common stock, par value $0.001 per share (the "Common Stock")

Company's Certificate of Designations, Preferences and Rights of the Preferred
Stock, in the form attached hereto as Exhibit A (the "Certificate of

Buyer does not agree to hold any of the Securities for any minimum or other
specific term and reserves the right to dispose of the Securities at any time,
provided further, however, that such disposition shall be in accordance with or
pursuant to a registration statement or an exemption under the 1933 Act.

        b. Accredited Investor Status. Such Buyer is an "accredited investor" as
           --------------------------
that term is defined in Rule 501(a)(3) of Regulation D under the 1933 Act.

           ----------------------
are being offered and sold 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
Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Buyer set forth herein in order to
determine the availability of such exemptions and the eligibility of such Buyer
to acquire the Securities.


        d. Information. Such Buyer and its advisors, if any, have been furnished
           -----------
with all materials relating to the business, finances and operations of the

        e. No Governmental Review. Such Buyer understands that no United States
           ----------------------
federal or state agency or any other government or governmental agency has

authorities passed upon or endorsed the merits of the offering of the
Securities.

        f. Transfer or Resale. Such Buyer 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 Buyer 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 Buyer
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.

           -------
instruments representing the Preferred Shares and, until such time as the sale
of the Conversion Shares have been registered under the 1933 Act as contemplated
by the Registration Rights Agreement, the stock certificates representing 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.

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

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 Buyer
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.

        h. Authorization; Enforcement; Validity. This Agreement and the
           ------------------------------------
Registration Rights Agreement have been duly and validly authorized, executed

of directors or similar governing body of such entity) are corporations duly
organized and validly existing in good standing under the laws of the

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
Certificate of Designations. A complete list of entities in which the Company,

to registration of 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 a Buyer
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 Buyer 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 Buyer 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 Conversion Shares, promptly instruct its transfer agent to issue one
or more certificates in such name and in such denominations as specified by such
Buyer and without any restrictive legend. The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the Buyers 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 Buyers 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.

           ---------
before issuance any press releases or any other public statements with respect
to the transactions contemplated hereby; provided, however, that the Company
shall be entitled, without the prior approval of any Buyer, to make any press
release or other public disclosure with respect to such transactions as is
required by applicable law and regulations (although each Buyer shall be
consulted by the Company in connection with any such press release or other
public disclosure prior to its release and shall be provided with a copy
thereof).

        k. 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.

        l. Termination. In the event that the Initial Closing shall not have
           -----------
occurred with respect to a Buyer on or before five (5) Business Days from the
date hereof due to the Company's or such Buyer's failure to satisfy the
conditions set forth in Sections 6(a) and 7(a) 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(l), the Company shall remain obligated to reimburse
any nonbreaching Buyer for the expenses described in Section 4(l) above.

        m. Placement Agent. The Company acknowledges that it has not engaged a
           ---------------
placement agent in connection with the sale of the Preferred Shares, however the
Company has engaged Chase H&Q Securities Corp. and Friedman, Billings & Ramsey,
Inc. as financial advisors in connection with the sale of the Preferred Shares.
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.

        n. 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.

        o. Remedies. Each Buyer and each holder of the Securities shall have all
           --------
rights and remedies set forth in the Transaction Documents and the Certificate
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.

        p. Payment Set Aside. To the extent that the Company makes a payment or
           -----------------
payments to any Buyer hereunder or pursuant to the Registration Rights
Agreement, the Certificate of Designations or the Buyers 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.
