Each Customer must withdraw a minimum of 19% of its Maximum Customer Inventory

by December 31 of each year (19% Requirement). "Maximum Customer Inventory"

equals the Customer's total inventory at the start of the withdrawal season.

MRT will supply each Customer with an individual storage deliverability curve

prior to each withdrawal cycle.

4.2 Each Rate Schedule FSS Customer must submit a preliminary daily

withdrawal schedule by 10:00 a.m. CST at least fifteen (15) calendar days

prior to the beginning of each withdrawal month. Customers must nominate

daily withdrawals in accordance with the nomination procedures and deadlines

set forth in Section 8 of the General Terms and Conditions.

4.3 Except as set forth in Sections 4.4 and 9.1 of this rate schedule,

or as provided for in Section 14.15 of the General Terms and Conditions, Rate

Schedule FSS Customers shall not be permitted to exceed the maximum monthly

withdrawal amounts set forth in the withdrawal schedule under Section 4.1. If

a Customer's monthly withdrawals are deficient by more than 5% of its Minimum

Monthly Withdrawal Requirement and such deficiencies are not the result of

operational constraints on MRT's system, the Customer shall pay a penalty of

$10.00 per Dth for quantities left in storage which exceed the 5% tolerance.

If a Customer fails to withdraw 19% of its Maximum Customer Inventory by
