GENERAL TERMS AND CONDITIONS (Continued)

51. NEGOTIATED RATES (Continued)

51.1 Purpose: This Section 51 allows Transporter and Shipper to

negotiate a rate for service under the applicable Rate Schedules

contained in this Tariff. The rate or rates to be charged may be

negotiated in form and/or level from the maximum-to-minimum ranges set

forth on the Notice of Currently Effective Rates of this Tariff.

51.2 Conditions: Implementation of a negotiated rate shall be

subject to the following conditions:

51.2.1 Transporter may, at its option, require that Shippers

making negotiated rate bids or negotiated rate requests for any

available capacity first have an executed Part 284 Service

Agreement prior to implementing negotiated rates. Transporter

and any Shipper using capacity acquired under a capacity-release

arrangement, may mutually agree to convert that Service Agreement

to a Service Agreement subject to negotiated rates.

51.2.2 Shipper had access to the Recourse Rate at the time of

the execution of the Service Agreement implementing negotiated

rates. The Recourse Rate will not be available to either party

during the term of a negotiated rate Service Agreement except

upon mutual agreement.

51.2.3 Transporter has filed either the applicable Service

Agreement or a tariff sheet advising the FERC of such agreement.

The numbered tariff sheet will state the exact legal name of the

Shipper, the negotiated rate, other applicable charges, the

receipt and delivery points, the volume of gas to be transported

and the applicable Rate Schedule for service provided at a

negotiated rate. The tariff sheet will include a statement

affirming that the applicable Service Agreement does not deviate

in any material aspect from the Form of Service Agreement in this

Tariff. A negotiated rate shipper may amend primary receipt and

delivery points pursuant to Section 12.5 of these General Terms

and Conditions. All such primary receipt and delivery points are

posted on Transporter's Interactive Website daily and will not

necessitate the refiling of the applicable Service Agreement or

tariff sheet with the FERC.

51.2.4 A negotiated rate shipper is additionally subject to

all applicable surcharges and any applicable fuel reimbursement

charges.
