     6.3  Customer shall have the right in its sole discretion to reject or
return all or any portion of any Order that is not delivered to a designated
carrier on the date specified in the Order, time being of the essence of this
Agreement. Upon written demand from Customer, Manufacturer shall promptly
refund any payment made by Customer in respect of such rejected Order or
portion thereof.

7.   ACCEPTANCE AND INSPECTION
