2. REPRESENTATIONS BY PARTICIPANT. In consideration of the Company's acceptance
of participation, I make the following representations and warranties to the
Company, to its principals, and to participating broker-dealers, if any, jointly
and severally, which warranties and representations shall survive any acceptance
of my participation in the Shares:

      (a) I have had the opportunity to ask questions and receive any additional
information from persons acting on behalf of the Company to verify my
understanding of the terms thereof and of the Company's business and status
thereof, and that no oral information furnished to the undersigned or my
advisors in connection with my participation in the Shares has been in any way
inconsistent with other documentary information provided.

      (b) I acknowledge that I have not seen, received, been presented with, or
been solicited by any leaflet, public promotional meeting, newspaper or magazine
article or advertisement, radio or television advertisement, or any other form
of advertising or general solicitation with respect to my participation in the
Shares.

      (c) The Shares are being purchased for my own account for long-term
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meanings of the Securities
Act of 1933, as amended (the "Securities Act"), and any applicable state
securities laws. No other person or entity will have any direct or indirect
beneficial interest in, or right to, the Shares. I or my agents or investment
advisors have such knowledge and experience in financial and business matters
relating to an investment of this type that will enable me to utilize the
information made available to me in connection with the participation in the
Shares to evaluate the merits and risks of participation and to make an informed
investment decision.

      (d) I understand that (A) the Shares (1) have not been registered under
the Securities Act or any state securities laws, (2) will be issued in reliance
upon an exemption from the registration and prospectus delivery requirements of
the Securities Act pursuant to Section 4(2) and/or Regulation D thereof and (3)
will be issued in reliance upon exemptions from the registration and prospectus
delivery requirements of state securities laws which relate to private
offerings, and (B) I must therefore bear the economic risk of such investment
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act and applicable state securities laws or is exempt therefrom. I
further understand that such exemptions depend upon, among other things, the
bona fide nature of my investment intent as expressed herein. Pursuant to the
foregoing, I acknowledge that the certificates representing the Shares acquired
pursuant to this Subscription shall bear a restrictive legend substantially as
follows:

<PAGE>

            "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
            RESTRICTIONS ON TRANSFER UNDER THE SECURITIES ACT OF 1933, AS
            AMENDED, AND STATE SECURITIES LAWS, AND MAY NOT BE OFFERED FOR SALE,
            SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS
            (I) REGISTERED UNDER THE APPLICABLE SECURITIES LAWS OR (II) AN
            OPINION OF COUNSEL, WHICH OPINION AND COUNSEL ARE BOTH REASONABLY
            SATISFACTORY TO THE COMPANY, HAS BEEN DELIVERED TO THE COMPANY AND
            SUCH OPINION STATES THAT THE SHARES MAY BE TRANSFERRED WITHOUT SUCH
            REGISTRATION."

      (e) I acknowledge that I have been advised that:

            (i) The Shares offered hereby have not been approved or disapproved
by the Securities and Exchange Commission ("SEC") or any state securities
commission nor has the SEC or any state securities commission passed upon the
accuracy or adequacy of any representations by the Company. Any representation
to the contrary is a criminal offense.

            (ii) In making an investment decision, I must rely on my own
examination of the Company and the terms of the offering of the Shares,
including the merits and risks involved. The Shares have not been recommended by
any federal or state securities commission or regulatory authority. Furthermore,
the foregoing authorities have not confirmed the accuracy or determined the
adequacy of any representation. Any representation to the contrary is a criminal
offense.

            (iii) The Shares are "Restricted Securities" within the meaning of
Rule 144 under the Securities Act, are subject to restrictions on
transferability and resale and may not be transferred or resold except as
permitted under the Securities Act and applicable state securities laws,
pursuant to registration or exemption therefrom.

      (f) Other than the rights specifically set forth in the WWT Registration
Rights Agreement, I represent, warrant and agree that the Company and the
officers of the Company (the "Company's Officers") are under no obligation to
register or qualify the participation in the Shares under the Securities Act or
under any state securities law, or to assist the undersigned in complying with
any exemption from registration and qualification.

      (g) I represent that I am an "accredited investor" within the meaning of
Rule 501 of Regulation D under the Securities Act and I have executed the
Certificate of Accredited Investor Status, attached hereto as Exhibit A.

      (h) I understand that the participation in the Shares is illiquid, cannot
be readily sold as there will not be a public market for them and that I may not
be able to sell or dispose of my participation in the Shares, or to utilize the
Shares as collateral for a loan. I understand that the purchase of the Shares is
a speculative investment and involves substantial risks and that I could lose my
entire investment in the Shares. I must not purchase participation in the Shares
unless I have liquid assets sufficient to assure myself that such purchase will
cause me no undue financial difficulties and that I can still provide for my
current and possible personal contingencies, and that the commitment herein for
participation in the Shares, combined with other investments of mine, is
reasonable in relation to my net worth.

<PAGE>

      (i) I understand that my right to transfer my participation in the Shares
will be restricted against transfers unless the transfer is not in violation of
the Securities Act, the California Securities Law, and any other applicable
state securities laws (including investment suitability standards), that the
Company will not consent to a transfer of participation in the Shares unless the
transferee represents that such transferee meets the financial suitability
standards required of an initial participant and that the Company has the right,
in its absolute discretion, to refuse to consent to such transfer.

      (j) I have been advised to consult with my own attorney or attorneys
regarding all legal matters concerning an investment in the Company and the tax
consequences of participation in the Shares, and have done so, to the extent I
consider necessary.

      (k) I acknowledge that the tax consequences to me of investing in the
Company will depend on my particular circumstances, and neither the Company, the
Company's officers, any other investors, nor the partners, shareholders,
members, managers, agents, officers, directors, employees, affiliates or
consultants of any of them, will be responsible or liable for the tax
consequences to me of an investment in the Company. I will look solely to and
rely upon my own advisers with respect to the tax consequences of this
investment.

      (l) I acknowledge that I have made the decision to invest in the Shares
solely on the basis of the information set forth in the Company's Private
Placement Memorandum (the "Memorandum"), dated _______________________, 2004,
included herewith, and that no officer, director, or other person affiliated
with the Company has given me any information or made any representations, oral
or written, other than as provided in the Memorandum, on which I have relied
upon in deciding to invest in the Shares, including without limitation, any
information with respect to future operations of the Company or the economic
returns which may accrue as a result of the purchase of the Shares.

      (m) All information which I have provided to the Company concerning
myself, my financial position and my knowledge of financial and business matters
is truthful, accurate, correct and complete as of the date set forth herein. I
agree to furnish the Company such other information as the Company may
reasonably request in order to verify the accuracy of the information contained
herein and agree to notify the Company immediately of any material change in the
information provided herein that occurs prior to the Company's acceptance of
this Subscription.

      (n) I and my affiliates do not have, and during the 30 day period prior to
the date of this Subscription, I and my affiliates have not entered into, any
"put equivalent position" or short sale positions with respect to the Common
Stock.

      (o) If I am not a United States person, I hereby represent that I have
satisfied myself as to the full observance of the laws of my applicable
jurisdiction in connection with any invitation to subscribe for the Shares or
any use of this Subscription, including (i) the legal requirements within such
jurisdiction for the purchase of the Shares, (ii) any foreign exchange
restrictions applicable to such purchase, (iii) any governmental or other
consents that may need to be obtained, and (iv) the income tax and other tax
consequences, if any, that may be relevant to the purchase, holding, redemption,
sale or transfer of the Shares. My subscription and payment for, and my
continued beneficial ownership of the Shares, will not violate any applicable
securities or other laws of such jurisdiction.

3. AGREEMENT TO INDEMNIFY COMPANY. I hereby agree to indemnify and hold harmless
the Company, its principals, the Company's officers, directors and attorneys,
from any and all damages, costs and expenses (including actual attorneys' fees)
which they may incur (i) by reason of my failure to fulfill any of the terms and
conditions of participation, (ii) by reason of my breach of any of my
representations, warranties or agreements contained herein; (iii) with respect
to any and all claims made by or involving any person, other than me personally,
claiming any interest, right, title, power or authority in respect to my
participation. I further agree and acknowledge that these indemnifications shall
survive any sale or transfer, or attempted sale or transfer, of any portion of
my participation.
