representations in Section 2.2 of the Loan Agreement, as of the date hereof.
 
(b)  The Company also represents and warrants that:
 
(i) Upon issuance in accordance with this Agreement, the Initial Conversion
Shares will be duly authorized, validly issued, fully paid and nonassessable and

transferred and other than any taxes due because of actions by a Lender), liens
and charges with respect to the issue thereof and the holders of such Initial
Conversion Shares shall be entitled to all rights and preferences accorded to a
holder of  shares of the Company’s common stock.
 
(ii) Assuming (without any independent investigation or verification by or on
behalf of the Company) the accuracy of the representations and warranties of the
Lenders set forth in the Loan Agreement, the issuance of the amended and
restated Notes are exempt from registration under Section 5 of the Securities

take any action which might subject the offering, issuance or sale of the Notes
to the registration requirements of Section 5 of the Securities Act.
 
(c)  The Company agrees to use its best efforts to obtain within one (1) year
from the date hereof the requisite stockholder and AMEX approvals described in
the Amended and Restated Notes, as well as AMEX’s approval for the listing of
the Initial Conversion Shares on AMEX.
 
(d)  The Company further agrees that upon obtaining the requisite stockholder
and AMEX approvals described in the Amended and Restated Notes and upon issuance
in accordance with this Agreement, the Loan Agreement, and the terms of the
Amended and Restated Notes, the Conversion Shares into which the Amended and
Restated Notes are convertible will be duly authorized, validly issued, fully
paid and nonassessable and free from all taxes (other than transfer taxes where
the Amended and Restated Notes have been transferred and other than any taxes
due because of actions by a Lender), liens and charges with respect to the issue
thereof and the holders of such Conversion Shares shall be entitled to all
rights and preferences accorded to a holder of  shares of the Company’s Common
Stock
 
7.  Stock Legends.  Each Lender agrees to the imprinting, so long as is required
by this Section 5, of the following legend on its Amended and Restated Notes,
the Initial Conversion Shares and Conversion Shares:
 
THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED WITH THE SECURITIES
AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT
PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
APPLICABLE STATE SECURITIES LAWS.
 
The Initial Conversion Shares and Conversion Shares shall not contain the legend
set forth above if the issuance thereof occurs at any time while the
registration statement (“Registration Statement”) filed pursuant to the
Registration Rights Agreement is effective under the Securities Act, or in the
event that the Initial Conversion Shares and Conversion Shares may be sold
pursuant to Rule 144(k) under the Securities Act.  The Company agrees that it
will provide each Lender, upon request, with a certificate or certificates
representing Initial Conversion Shares or Conversion Shares free from such
legend at such time as such legend is no longer required hereunder.  Each Lender
agrees that, in connection with any transfer of Initial Conversion Shares or
Conversion Shares by it pursuant to an effective registration statement under
the Securities Act, it will comply with the prospectus delivery requirements of
the Securities Act provided copies of a current prospectus relating to such
effective registration statement are or have been supplied to such Lender.
 
8.  Press Release.  The Company and the Lenders shall consult with each other in
issuing any press releases or otherwise making public statements with respect to
the transactions contemplated hereby and neither the Company nor any Lender
shall issue any such press release or otherwise make any such public statement
without the prior consent of the other, which consent shall not be unreasonably
withheld or delayed, except that no prior consent shall be required if such
disclosure is required by law, in which such case the disclosing party shall
provide the other party with prior notice of such public statement.
 
9.  Miscellaneous.
 
(a)           As modified hereby, the Loan Documents shall remain in full force
and effect.
 
(b)           The Company shall, upon request of the Lenders, reimburse them for
their legal expenses incurred in the preparation of this Agreement and for
related transactions.
