RATE SCHEDULE TF-2

TRANSPORTATION SERVICE - FIRM

(Continued)

Upon Shipper's request, Transporter shall provide a written

explanation of any credit limitation applied to Shipper.

Transporter may require Shipper to deposit with Transporter and

maintain, on prepaid account, or to establish and maintain an

escrow account or to furnish a letter of credit in an amount equal

to Transporter's estimate of 2 Months of charges for performing

such service at the level of Shipper's Maximum Delivery Quantity

or to furnish within 15 Days, good and sufficient security, as

determined solely by Transporter, of a continuing nature and in an

amount equal to Transporter's estimate of 2 Months of charges for

performing said service at the level of Shipper's Maximum Delivery

Quantity, or may require such other measures as Transporter may

specify. Transporter will also permit another entity to guarantee

in writing Shipper's obligation, provided that the guarantor has

sufficient credit available, as determined by Transporter in

accordance with this provision. Transporter may, without waiving

any rights or remedies it may have, suspend further service until

such acceptable security is received by Transporter. Upon

Shipper's establishment of an acceptable credit record or upon

expiration of the Agreement, Transporter shall refund Shipper's

deposit with interest accrued at rates set pursuant to 18 CFR

Section 154.501(d).

7.3 Agents. Shipper must provide written notice to Transporter of the

name, and any other pertinent information, of another person

("Agent") that has agency authority to act for Shipper pursuant to

an Agreement under this Rate Schedule TF-2 in connection with

(1) the Joint Monthly Operating Plan as discussed in Article 7 of

the General Terms and Conditions of this tariff, (2) operation of

pipelines, facilities, and wells, in connection with an Agreement

under this Rate Schedule, (3) Operational Flow Orders and

Configuration Flow Orders as discussed in Article 7 of the General

Terms and Conditions of this tariff, and/or (4) other matters

covered by an Agreement. If the Agent has the authority in (2)

and (3), above, operating notices shall be served upon the Agent

alone. The Shipper remains bound by its obligations under an

Agreement, and commitments made by the Agent on behalf of the

Shipper are binding on the Shipper as if made by the Shipper. The

Shipper must provide prompt written notice of the termination of

the agency.
