                (j)

              	
                The
      Debtor will, at such times as the Secured Parties may request, deliver to
      the Secured Parties a schedule identifying the Collateral subject to the
      security interest of this Security Agreement, and such additional
      schedules, certificates, and reports respecting all or any of the
      Collateral at the time subject to the security interest of this Security
      Agreement, and the items or amounts received by the Debtor in full or
      partial payment or otherwise as proceeds received in connection with any
      Collateral.  Any such schedule, certificate or report shall be
      executed by a duly authorized officer of the Debtor on behalf of the
      Debtor and shall be in such form and detail as the Secured Parties may
      specify. The Debtor shall immediately notify the Secured Parties of the
      occurrence of any event causing loss or depreciation in the value of the
      Collateral, and the amount of such loss or
  depreciation.

              


      

      


      
        
          	
                	
                  (k)

                	
                  If
      and when so requested by the Secured Parties, the Debtor will stamp on the
      records of
      the Debtor concerning the Collateral a notation, in a form satisfactory to
      the Secured Parties, of the security interest of the Secured Parties under
      this Security Agreement.

                


        

      

      


      Section
4.      Disposition
of Collateral in Ordinary Course.  Debtor shall not sell,
transfer, assign, convey, license, grant any right to use or otherwise dispose
of any Collateral  except in the ordinary course of business, without
the prior written consent of the Secured Parties.

      


      Section
5.      Secured
Parties May Perform.  Upon the occurrence and continuation of
an “Event of
Default” under the Notes, at the option of the Secured Parties, the
Secured Parties may discharge taxes, liens or security interests, or other
encumbrances at any time hereafter levied or placed on the Collateral; may pay
for insurance required to be maintained on the Collateral pursuant to Section 3;
and may pay for the maintenance and preservation of the
Collateral.  The Debtor agrees to reimburse the Secured Parties on
demand for any payment made, or any expense incurred, by the Secured Parties
pursuant to the foregoing authorization.  Until the occurrence and
continuation of an Event of Default, the Debtor may have possession of the
Collateral and use it in any lawful manner not inconsistent with this the
Security Agreement.

      


      Section
6.      Obligations
Secured; Certain Remedies.  This Security Agreement secures the
payment and performance of all obligations of the Debtor to the Secured Parties
under the Notes, whether now existing or hereafter arising and whether for
principal, interest, costs, fees or otherwise (collectively, the “Obligations”).  Upon
the occurrence and continuation of an Event of Default under the Notes, the
Secured Parties may declare all obligations secured hereby immediately due and
payable and may exercise the remedies of a secured party under the Uniform
Commercial Code.  Without limiting the foregoing, the Secured Parties
may require the Debtor to assemble the Collateral and make it available to the
Secured Parties at a place to be designated by the Secured Parties which is
reasonably convenient to both parties or to execute appropriate documents of
assignment, transfer and conveyance, in each case, in order to permit the
Secured Parties to take possession of and title to the
Collateral.  Unless the Collateral is perishable or threatens to
decline rapidly in value or is of a type customarily sold on a recognized
market, the Secured Parties will give the Debtor reasonable notice of the time
and place of any public sale thereof or of the time after which any private sale
or any other intended disposition thereof is to be made.  The
requirements of reasonable notice shall be met if such notice is mailed to the
Debtor via registered or certified mail, postage prepaid, at least fifteen (15)
days before the time of sale or disposition.  Expenses of retaking,
holding, preparing for sale, selling or the like, shall include the Secured
Parties’ reasonable attorneys’ fees and legal expenses.

      Section
7.      Debtor
Remains Liable.  Anything herein to the contrary
notwithstanding:

      


      
        	
                 
      

              	
                (a)

              	
                Notwithstanding
      the exercise of any remedy available to the Secured Parties hereunder or
      at law in connection with an Event of Default, the Debtor shall remain
      liable to repay the balance remaining unpaid and outstanding under the
      Notes after the value or proceeds received by the Secured Parties in
      connection with such remedy is subtracted.  The Secured Parties
      shall promptly deliver and pay over to the Debtor any portion of the value
      or proceeds received in connection with such remedy that remains after the
      unpaid and outstanding portion of the Notes is paid in
    full.

              


      

      


      
        	
                 
      

              	
                (b)

              	
                The
      Debtor shall remain liable under the contracts and agreements included in
      the Collateral to the extent set forth therein, and shall perform all of
      its duties and obligations under such contracts and agreements to the same
      extent as if this Security Agreement had not been
  executed.

              


      

      


      
        	
                 
      

              	
                (c)

              	
                The
      exercise by the Secured Parties of any of its rights hereunder shall not
      release the Debtor from any of its duties or obligations under any such
      contracts or agreements included in the
  Collateral.

              


      

      


      
        	
                 
      

              	
                (d)

              	
                The
      Secured Parties shall not have any obligation or liability under any such
      contracts or agreements included in the Collateral by reason of this
      Security Agreement, nor shall the Secured Parties be obligated to perform
      any of the obligations or duties of the Debtor thereunder or to take any
      action to collect or enforce any claim for payment assigned
      hereunder.

              


      

      


      Section
8.      Security
Interest Absolute.  All rights of the Secured Parties and the
security interests granted to the Secured Parties hereunder shall be absolute
and unconditional, to the maximum extent permitted by law, irrespective
of:

      


      
        	
                 
      

              	
                (a)

                (b)

              	
                Any
      change in the time, manner or place of payment of, or in any other term
      of, all or any part of the Obligations or any other amendment to or waiver
      of or any consent to any departure from the Notes or any other document or

          4

          
            

          

        

        
           

        

      

      
 

      
        	
                 
      

              	
                (c)

              	
                Any
      exchange, release or non-perfection of any collateral (including the
      Collateral), or any release of or amendment to or waiver of or consent to
      or departure from any guaranty, for all or any of the Obligations;

                (d)

              	
                Any
      other circumstance which might otherwise constitute a defense available
      to, or a discharge of, the Debtor, a guarantor or a third party grantor of
      a security interest.
