5.3  Unregistered
Securities.




(a)  Holder
must bear the economic risk of investment for an indefinite period of time
because the Securities have not been registered under the Act and therefore
cannot and will not be sold unless they are subsequently registered under the
Act or an exemption from such registration is available.  The Company
has made no agreements, covenants or undertakings whatsoever to register the
Securities under the Act other than pursuant to an investor rights
agreement.  The Company has made no representations, warranties or
covenants whatsoever as to whether any exemption from the Act, including,
without limitation, any exemption for limited sales in routine brokers’
transactions pursuant to Rule 144 under the Act, will become available and any
such exemption pursuant to Rule 144, if available at all, will not be available
unless: (i) a public trading market then exists in the Company’s common stock,
(ii) adequate information as to the Company’s financial and other affairs and
operations is then available to the public, and (iii) all other terms and
conditions of Rule 144 have been satisfied.




(b)  Transfer of the Securities has not been registered or qualified under any
applicable U.S. state law regulating securities and therefore the Securities
cannot and will not be sold unless they are subsequently registered or qualified
under any such act or an exemption therefrom is available.  The
Company has made no agreements, covenants or undertakings whatsoever to register
or qualify the Securities under any such act.  The Company has made no
representations, warranties or covenants whatsoever as to whether any exemption
from any such act will become available. The Holder, however, shall be entitled
to a piggy-back registration right for the shares that may be issued to the
Holders pursuant to this Note.

investor” within the meaning of Regulation D of the rules and regulations
promulgated under the Act.

or modified only upon the written consent of the Company and
Holder.
