Return Materials Authorization (RMA) from Seller, which RMA Seller agrees to provide
Purchaser promptly upon request, (c) the defective Goods are returned to Seller,
transportation and other applicable charges prepaid by the Purchaser, and (d) Seller’s
examination of such Goods discloses to its reasonable satisfaction that defects were not
