ANY ACCELERATION OF SELLER'S OBLIGATIONS HEREUNDER.  FURTHER,

"DEFAULT" OR "PAST DUE" RATE SHALL NOT BE DEEMED A WAIVER BY
PURCHASER OF ITS CLAIM THERETO.

       13.3    Effect of Default.

       13.3.1  Upon the occurrence of any Event of Default, in
addition to any rights Purchaser has under this Agreement or

due and payable without notice.

     14.  Account Stated.  From time to time during the term of
this Agreement, Purchaser may render to Seller a statement

shall be considered correct and binding upon Seller as an account
stated, except to the extent that Purchaser receives, within ten
(10) days after the receipt of such statement, written notice
from Seller of any specific exceptions by Seller to that
statement, and then it shall be binding against Seller as to any
items to which it has not objected.

     15.  Waiver.  No failure to exercise and no delay in
exercising any right, power, or remedy hereunder shall impair any
right, power, or remedy which Purchaser may have, nor shall any
such delay be construed to be a waiver of any of such rights,
powers, or remedies, or any acquiescence in any breach or default
hereunder; nor shall any waiver by Purchaser of any breach or
default by Seller hereunder be deemed a waiver of any default or
breach subsequently occurring.  All rights and remedies granted
to Purchaser hereunder shall remain in full force and effect
notwithstanding any single or partial exercise of, or any
discontinuance of action begun to enforce, any such right or
remedy.  The rights and remedies specified herein are cumulative
and not exclusive of each other or of any rights or remedies that
Purchaser would otherwise have.  Any waiver, permit, consent or

       16.4    Upon termination, Seller shall pay the Obligations
to Purchaser, and Purchaser shall not purchase any Accounts from
Seller. Termination of this Agreement shall not affect the rights
and obligations of the parties hereunder with respect to
transactions occurring on or prior to the date of such
termination, and this Agreement shall continue to govern the
rights and obligations of the parties hereto with respect to
accounts purchased  by Purchaser from Seller on or prior to the
date of such termination.  All security interests granted or
contemplated by this Agreement shall survive the termination of
this Agreement until all amounts payable to Purchaser with
respect to transactions occurring on or prior to the date of
termination have been paid to Purchaser, and Seller has performed
all its obligations to Purchaser with respect to such
transactions and all obligations under this Agreement including
but not limited to payment of any fees owing hereunder.

     17.  Amendment.  Neither this Agreement nor any provisions
hereof may be changed, waived, discharged or terminated, nor may
any consent to the departure from the terms hereof be given,
orally (even if supported by new consideration), but only by an
instrument in writing signed by all parties to this Agreement.
Any waiver or consent so given shall be effective only in the
specific instance and for the specific purpose for which given.

     18.  No Lien Termination without Release.  In recognition of
the Purchaser's right to have its attorneys' fees and other
expenses incurred in connection with this Agreement secured by
the Collateral, notwithstanding payment in full of all
Obligations by Seller, Purchaser shall not be required to record
any terminations or satisfactions of any of Purchaser's liens on
the Collateral unless and until Seller has executed and delivered
to Purchaser a general release in the form of Exhibit A hereto.
Seller understands that this provision constitutes a waiver of
its rights under Section 9-513 of the UCC.

     19.  Conflict.  Unless otherwise expressly stated in any
other agreement between Purchaser and Seller, if a conflict
exists between the provisions of this Agreement and the
provisions of such other agreement, the provisions of this
Agreement shall control.

     20.  Survival.  All representations, warranties and
agreements of Seller herein contained shall be effective so long
as any portion of this Agreement remains executory.

     21.  Severability.  In the event any one or more of the
provisions contained in this Agreement is held to be invalid,
illegal or unenforceable in any respect, then such provision
shall be ineffective only to the extent of such prohibition or
invalidity, and the validity, legality, and enforceability of the
remaining provisions contained herein shall not in any way be
affected or impaired thereby.

     22.  Enforcement.  This Agreement and all agreements
relating to the subject matter hereof is the product of
negotiation and preparation by and among each party and its
respective attorneys, and shall be construed accordingly.
