condition of the Company and to obtain additional information (to the extent the
Company possessed such information or could acquire it without unreasonable
effort or expense) necessary to verify the accuracy of any information furnished
to such Investor or to which such Investor had access. The foregoing, however,
does not limit or modify the representations and warranties of the Company in
Section 2 of this Agreement.

     3.5  Investment Experience.  Such Investor is experienced in evaluating and
investing in private placement transactions of securities of companies in a
similar stage of development to the Company and acknowledges that such Investor
is able to fend for itself, can bear the economic risk of such Investor's
investment and has such knowledge and experience in financial and business
matters that such Investor is capable of evaluating the merits and risks of the
investment in the Series K Preferred Stock. If other than an individual, such
Investor has not been organized for the purpose of acquiring the Series K
Preferred Stock.

     3.6  Accredited Investor.  Such Investor is an "accredited investor" as
defined in Rule 501 promulgated under the Securities Act.

     3.7  Restricted Securities.  Such Investor understands that the Series K
Preferred Stock, the Warrants, and the Common Stock issuable upon conversion or
exercise thereof (as the case may be) may not be sold, transferred or otherwise
disposed of without registration under the Securities Act or exemption
therefrom, and that in the absence of an effective registration statement
covering such securities or an available exemption from registration under the
Securities Act, such securities must be held indefinitely. In  particular, such
Investor is aware that such securities may not be sold pursuant to Rule 144
promulgated under the Securities Act unless all of the conditions of that rule
are met. Among the conditions for use of Rule 144 may be the availability of
current information to the public about the Company. Such information is not now
available and the Company has no present plans to make such information
available.
