Section 2--512. Payment by Buyer Before Inspection.

(1) Where the contract requires payment before inspection
non-conformity of the goods does not excuse the buyer from so making
payment unless

(a) the non-conformity appears without inspection; or

(b) despite tender of the required documents the circumstances

would justify injunction against honor under this Code (Section

5--109(b)).

(2) Payment pursuant to subsection (1) does not constitute an
acceptance of goods or impair the buyer's right to inspect or any of his
remedies.
