Seller shall be retained by Seller and not assumed by Buyer, except as provided
herein for customer claims. Seller shall retain liability for any orders for

to Buyer in immediately available funds simultaneously with payment of the
Reserve to Buyer.

Buyer and Seller shall jointly prepare an analysis of adjustments to be made to
the payment made at Closing, to reflect the actual Purchase Price. If Buyer and

dispute shall be resolved by the CPA.

5.4     CUSTOMER CLAIMS FOLLOWING CLOSING. If customers who purchased inventory
from Seller prior to the Closing Date seek from Buyer customer service
adjustments for the windows purchased from Seller that are not covered by the
warranty from Marvin Windows & Doors, Buyer agrees to notify Seller of such
claim and to resolve such claim, if requested by Seller, at a cost agreed to by
Seller. All such resolved claims shall be charged against the Marvin Windows &
Doors sales service reimbursement credit issued by Marvin Windows & Doors for
the service rendered, and any claims in excess of such credit shall be paid by
Seller to Buyer.

5.5     STORAGE AND DELIVERY COSTS. Buyer shall assume and perform Seller's
contracts for windows sold to customers but not yet delivered as may be
