WHEREAS, the IRA was entered into by the RENN Funds on behalf of themselves and
for the benefit of the other then stockholders of the Company;

WHEREAS, the Company and the RENN Funds desire to amend the IRA.
 
               WHEREAS, Section 3.7 of the Agreement provides that Section 1 of

WHEREAS, the RENN Funds collectively hold a majority of the Registrable
Securities currently outstanding.

NOW, THEREFORE, it is agreed as follows:

1.   Hercules Technology Growth Capital, Inc.  The benefit of the IRA shall be
extended to the common stock of the Company that may be issued upon exercise by
Hercules Technology Growth Capital, Inc. (“Hercules”) of a certain warrant held
by it (the “Warrant”) to purchase shares of Series A Preferred Stock of the
Company (“Series A Preferred Stock”) and conversion of the Series A Preferred
Stock thereby acquired.  Without limiting the foregoing, (i) for the purposes of
Section 1 of the IRA, Hercules shall be deemed a “Preferred Stock
Investor”,  (ii) for all purposes under the IRA, the shares of Series A
Preferred Stock issuable upon exercise of the Warrant shall be deemed “Preferred
Stock” and Hercules shall be entitled to liquidated damages, if applicable,
pursuant to Section 1.11 of the IRA as modified by Section 3 below.
 
2.   Filing of Registration Statement.  The Initial Shelf Registration
Statement, as such term is defined in the IRA, shall be filed within 60 days
from the date of this Agreement.
 
3.   Failure to File Registration Statement and Other Events.  Without limiting
the foregoing, Hercules shall be entitled to the benefits of Section 1.11 of the
IRA modified as follows:  (i) in determining whether Hercules is entitled to
liquidated damages under Section 1.11, the “Filing Date”, as such term is
defined in the IRA, shall be the 60th day from the date of this Agreement, (ii)
Hercules’ “initial investment in the Preferred Stock”, as such term is used in
the IRA, shall be deemed to be the aggregate number of shares of Series A
Preferred Stock for which the Warrant is exercisable and (iii) if the Warrant
has not been exercised at any time when liquidated damages are due, such damages
shall accrue and be payable upon the exercise of the Warrant and on a pro rated
basis if the Warrant is not exercised in full.
