  3. If Western Digital instructs Supplier to purchase media space or time in a medium having a schedule of graduated rates and less space or time than contracted for is used so that a credit is due, Supplier shall promptly credit Western Digital for any excess amount Western Digital may have paid over the amount actually due at the rate earned.
