                  (d) The Debt Holder has adequate means of providing for its
current financial needs and contingencies, is able to bear the substantial
economic risks of an investment in the shares of Common Stock for an indefinite
period of time, has no need for liquidity in such investment, has made
commitments to investments that are not readily marketable which are reasonable
in relation to the Debt Holder's net worth and can afford a complete loss of
such investment.

                  (e) The Debt Holder has such knowledge and experience in
financial, tax and business matters so as to enable it to utilize the
information made available to it in connection with the offering of the shares
of Common Stock to evaluate the merits and risks of an investment in the shares
of Common Stock and to make an informed decision with respect to the exchange of
existing Debt Obligations for shares of Common Stock on the terms set forth
herein.

                  (f) The Debt Holder is not relying on the Company with respect
to the tax and other economic considerations of the exchange and an investment
in the shares of Common Stock to be issued in the exchange, and the Debt Holder
has relied on the advice of, or has consulted with, only the Debt Holder's own
advisors.

                  (g) The Debt Holder has full right and power to perform
pursuant to this Agreement and purchase shares of Common Stock of the Company
issued in the exchange and, if the Debt Holder is an entity, is authorized and
otherwise duly qualified to purchase and hold the shares of Common Stock and to
enter into this Agreement.

                  (h) The Debt Holder fully understands that the shares of
Common Stock have not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), or under the securities laws of certain states
and, therefore, cannot be resold, pledged, assigned or otherwise disposed of
unless the securities are subsequently registered under the Securities Act and
under the applicable securities laws of such states or unless an exemption from
such registration is available in the opinion of counsel reasonably satisfactory
to counsel for the Company. The Debt Holder is purchasing the shares of Common
Stock in the exchange for the Debt Holder's own account, for investment and not
with a view to resale or distribution except in compliance with the Securities
Act and applicable state securities laws. The Debt Holder further acknowledges
that there is presently no market for the purchase and sale of the shares of
Common Stock and that no such market may ever exist.

                  (i) The Debt Holder agrees to the placement of a legend on any
certificate or other document evidencing the shares of Common Stock, stating
that they have not been registered under the Securities Act.

                  (j) The representations, warranties and agreements contained
herein and in the related Investor Qualification Questionnaire are true and
correct as of the date hereof and may be relied upon by the Company, and the
Debt Holder will notify the Company immediately of any adverse change in any
such representations and warranties which may occur prior to the acceptance of
this Agreement by the Company and will promptly send the Company written
confirmation thereof. The representations, warranties and agreements of the Debt
Holder contained herein shall survive the execution and delivery of this
Agreement and the purchase of the shares of Common Stock in this exchange.
