Default, all proceeds of the sale of Subject Inventory or any Subject

and
(i)    Borrower shall enter into an intercreditor agreement in form and
substance satisfactory to the Administrative Agent in all respects with any
Commodity Intermediary party to any Commodity Intermediary Transaction.

Administrative Agent, to evidence the foregoing and consents to each such
amendment.
