provide Operator with Daily and cumulative balances of

overdeliveries and underdeliveries which are allocated to the

Agreement.

cause to be adjusted, the Nominations to the designated

Point(s) of Delivery to reduce the cumulative balance under the

Agreement to net to zero.

may require the Operator to cause a Nomination pursuant to Section

5.1 of the General Terms and Conditions to be made in the next

available Nomination cycle to eliminate no more than 10 percent of

its outstanding Rate Schedule SS-1 balance or up to 5,000 Dth on any

Day, whichever amount is greater, by the end of the next full Gas

Day under the following conditions:

a) The cumulative allocated balance under an Agreement at the end

of any Month is in the same direction as the previous Month

necessary to allow Transporter to fulfill higher priority

commitments, or is required as a result of Transporter's

operational requirements.
