Bank's duties in servicing and/or maintaining the Laurus Restricted Account,
except for acts of gross negligence or willful misconduct by Bank. IN NO EVENT,
HOWEVER, SHALL THE BANK HAVE ANY RESPONSIBILITY FOR CONSEQUENTIAL, INDIRECT,
SPECIAL OR EXEMPLARY DAMAGES OR LOST PROFITS, WHETHER OR NOT IT HAS NOTICE

OR THE COMPANY IN THE LAURUS RESTRICTED ACCOUNT. In furtherance of and without
limiting the foregoing, the Company and Laurus agree that the Bank shall not be
liable for any damage or loss to them for any delay or failure of performance
arising out of the acts or omissions of any third parties, including, but not
limited to, various communication services, courier services, the Federal

transactions, fire, mechanical, computer or electrical failures or other
unforeseen contingencies, strikes or any similar or dissimilar cause beyond the
reasonable control of the Bank. This paragraph shall survive the termination of
this Agreement.

assigns will release the Bank from and shall indemnify and hold the Bank
harmless from and against any and all losses, claims, damages, liabilities,
costs and expenses (including, without limitation, reasonable counsel fees,
whether arising in an action or proceeding among the parties hereto or
otherwise, without regard to the merit or lack of merit thereof) to which the
Bank may become subject, or which it may suffer or incur, arising out of or
based upon this Agreement or the actions contemplated hereby. This paragraph
shall survive termination of this Agreement.

         6. The Bank shall be fully protected in acting on any order or
direction by Laurus respecting the items received by the Bank or the monies or
other items in the Laurus Restricted Account without making any independent
inquiry whatsoever as to Laurus' rights or authority to give such order or
direction or as to the application of any payments made pursuant thereto.

         7. Nothing in this Agreement shall be deemed to prohibit the Bank from
complying with its customary procedures in the event that it is served with any
legal process with respect to the Laurus Restricted Account.

order to protect and further perfect its security interests in the Laurus
Restricted Account (including any amounts from time to time on deposit therein)
and are powers coupled with an interest and will be affected neither by any

         9. This Agreement may not be amended or waived except by an instrument
in writing signed by each of the parties hereto. This Agreement may be
terminated by the Bank upon giving the Company and Laurus thirty (30) days prior
written notice. Laurus shall designate a successor bank on or prior to the
