the outgoing Pool ("in-whole" basis). Transporter shall not be

Imbalance for each individual Pooling Area, as applicable.

Pool Manager pays a fee or charge as described in Section

5.7(c)(ii)(3) of Transporter's General Terms and Conditions, and

otherwise complies with the requirements of such sub-section.

Pool Managers can resolve Imbalances during the Month by revising

nominations, subject to the availability of capacity and

operational conditions. Any Imbalance remaining at the end of a

Month shall be cashed-out in accordance with the provisions of

Section 5.7(c)(ii) of Transporter's General Terms and Conditions.

Manager or any other Shipper as a result of Transporter's reliance

any and all losses, damages, expenses, claims, actions or

proceedings threatened, incurred or initiated as a result of

Transporter's reliance on such performance.
