RATE SCHEDULE IBS

INTERRUPTIBLE BALANCING SERVICE

-------------------------------

1. AVAILABILITY

(a) This Rate Schedule IBS is available to any entity

(hereinafter called Shipper) which: (i) submits to Midcontinent

Express Pipeline LLC (hereinafter called MEP) a valid request as

defined in Section 3 hereof; (ii) executes an Interruptible Balancing

Service Agreement (IBS Agreement) with MEP applicable to service

under this Rate Schedule IBS; and (iii) meets the qualifications set

out in subsection (b) of this Section.

(b) To be eligible for service under this Rate Schedule IBS,

the Shipper must identify the service under its IBS Agreement as

being for one specified end-use facility for each IBS Agreement;

except that more than one facility may be specified to the extent

limited aggregation of end-use facilities and points is permitted

under Section 7(c) of this Rate Schedule IBS. Such end-use facilities

need not be directly connected to MEP's system, but the conditions

specified in Section 3.2(c) of this Rate Schedule IBS must be met. To

be eligible for service hereunder, the Shipper must have and maintain

in effect an FTS or ITS Agreement to which the IBS Agreement is

linked, consistent with Section 3.2(a) of this Rate Schedule IBS. The

IBS Agreement must also specify a single Delivery Point for each end-

use facility; provided, however, that limited aggregation of end-use

facilities and points is permitted under Section 7(c) of this Rate

Schedule IBS. The Delivery Point may be any primary or secondary

Delivery Point available under the linked transportation Agreement

except for any Point on Leased Capacity; provided that the Delivery

Point must be consistent with the location of the end-use facility.

An IBS Agreement may only be linked to one transportation Agreement.

A transportation Agreement may have more than one IBS Agreement

linked to it, provided that the other requirements of this Rate

Schedule IBS are satisfied.

(c) The form of the IBS Agreement is contained in this

Tariff. There is no limitation on the number of IBS Agreements any

one Shipper may have.
