shall occur at the principal office of the Company simultaneously with the

Company will deliver to Purchaser a certificate representing the Shares to be

payment of the purchase price therefor by Purchaser by a check or wire transfer
from Purchaser to the Company.

     3.  Investment and Taxation Representations.  In connection with the
         ---------------------------------------
purchase of the Shares, Purchaser represents to the Company the following:

         (a) Purchaser has received all the information he considers necessary
or appropriate for deciding whether to purchase the Shares and has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Shares and the business, properties,
prospects, financial condition and results of operations of the Company.
Purchaser is aware of the Company's business affairs and financial condition and
has acquired sufficient information about the Company to reach an informed and
knowledgeable decision to acquire the Shares.

         (b) Purchaser is an investor in securities of companies in the
development stage and acknowledges that he is able to fend for himself, can bear
the economic risk of his investment, and has such knowledge and experience in
financial or business matters that he is capable of evaluating the merits and
risks of the investment in the Shares.

         (c) Purchaser is purchasing the Shares for investment for his own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act, and has no
present intention of selling, granting any participation
<PAGE>

in, or otherwise distributing the Shares. By executing this Agreement, Purchaser
further represents that he does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such
person or to any third person, with respect to any of the Shares.

         (d) Purchaser is an "accredited investor" within the meaning of
Securities and Exchange Commission ("SEC") Rule 501 of Regulation D under the
                                     ---
Act, as presently in effect.

         (e) Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available.  Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale.  Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

     4.  Restrictive Legends.
         -------------------

         (a)  Legends.  The certificate or certificates representing the Shares
              -------
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

         (i)  "These securities have not been registered under the Securities
Act of 1933, as amended.  They may not be sold, offered for sale, pledged or
hypothecated in the absence of a registration statement in effect with respect
to the securities under such act or an opinion of counsel satisfactory to the
company that such registration is not required or unless sold pursuant to Rule
144 of such act."

         (ii) Any legend required by the laws of the State of California,
including any legend required by the California Department of Corporations and
Sections 417 and 418 of the California Corporations Code.
