Obligations remain unpaid.

         9. No delay  or  failure  on  Laurus'  part in  exercising  any  right,
privilege or option  hereunder shall operate as a waiver of such or of any other
right, privilege, remedy or option, and no waiver whatever shall be valid unless
in writing,  signed by Laurus and then only to the extent therein set forth, and
no  waiver  by  Laurus of any  default  shall  operate  as a waiver of any other
default or of the same default on a future  occasion.  Laurus' books and records
containing  entries  with  respect to the  Obligations  shall be  admissible  in
evidence in any action or  proceeding,  shall be binding upon us for the purpose
of  establishing  the items therein set forth and shall  constitute  prima facie
proof  thereof.  Laurus  shall have the right to enforce  any one or more of the
remedies available to Laurus, successively, alternately or concurrently. Each of
the undersigned agree to join with Laurus in executing  financing  statements or
other instruments to the extent required by the Uniform  Commercial Code in form
