   1.1  Section 1.8 of the Sixth Amendment to Lease provides that Lessor and 
Lessee agree that all amounts referenced in the Addendum to Triple Net Lease 
(the "Addendum") attached as Exhibit A to the Sixth Amendment have been paid 
in full.  Lessor and Lessee now wish to acknowledge that as of the date of

Lessor and Lessee reserve all rights and defenses they may have with respect 
to the payment of such amount.  Nothing in this Amendment shall be construed 
as an acknowledgment by Lessee that any amounts remain due and owing or 
construed as extending the statute of limitations with respect to such 
payment.

2. STATUS OF LEASE.  Except as expressly amended hereby, the Lease remains 
in full force and effect and is hereby ratified and affirmed.

3. COUNTERPARTS.  This Amendment may be executed simultaneously or in 
counterparts, each of which shall be deemed an original, but all of 
which together shall constitute one and the same Amendment.

4. FACSIMILE TRANSMISSION.  Facsimile transmission of any signed original 
document, and retransmission of any signed facsimile transmission, 
shall be the same as delivery of an original.  At the request of either 
party, the parties shall confirm facsimile transmitted signatures by 
signing an original document.

   IN WITNESS WHEREOF, this Eighth Amendment to Lease has been executed as of 
the date set forth above.
