GENERAL TERMS AND CONDITIONS (Continued)

6.6 Monitoring.

(a) Transporter may monitor: (i) the daily production by or on behalf of any Shipper;

the daily tenders of gas by or on behalf of any Shipper; (ii) the quantities delivered by an

Intermediate Transporter (such as a local distribution company or other entity that receives

Shipper's gas from transporter) to Shipper or Shipper's end-user(s); and (iii) the daily usage of gas

by any Shipper or Shipper's end-user(s). Transporter may do so for the purpose of monitoring on an

hourly, daily, weekly, or monthly basis the quantities being tendered to and delivered by Transporter

and thereby to maintain, as nearly as possible, a concurrent balance between receipts and deliveries

of gas. The approximate quantities determined by Transporter in that monitoring process shall be

referred to herein as Monitored Quantities.

(b) Monitoring may be performed by Transporter using either the estimates or actual data

received by Transporter pursuant to this Section or actual meter readings by Transporter.

Transporter may make reasonable prospective adjustments to Shipper's Scheduled Daily Delivery

Quantity and Scheduled Daily Receipt Quantity based upon either the Monitored Quantities or the

actual data received by Transporter pursuant to the provisions of this Section. Any such adjustments

by Transporter shall not result in Shipper's incurrence of any penalty if Transporter, in making such

adjustment, relied upon inaccurate estimates, inaccurate meter readings, or inaccurate data received

by Transporter pursuant to this Section. Transporter may make such adjustments upon Electronic

Notice Delivery or telephonic notice to Shipper 24 hours in advance of the effective time of the

adjustment (or, in the case of intra-day changes in nominations, upon reasonable notice to the

Shipper being bumped); provided, however, that Transporter need not provide any advance notice in the

event of adjustments resulting from: (i) interruptions of Shipper's service pursuant to Section 16

(Interruptions of Service) of the General Terms and Conditions; (ii) operational flow orders issued

by Transporter pursuant to Section 17 (Operational Flow Orders) of the General Terms and Conditions;

or (iii) the cessation of deliveries pursuant to Section 6.3(e). Transporter need not provide any

advance notice of interruptions or OFO's except as provided for in Sections 16 and 17, respectively.

Transporter also shall have the right to notify any entity described at paragraphs (c) and (d) of

this Section of the revised Scheduled Daily Receipt Quantities it will accept on behalf of Shipper.

regarding production or tenders to Transporter on behalf of Shipper from any entity (i) from whom

Shipper is purchasing gas for tender to Transporter, or any other brokers or resellers of such gas;

(ii) that is delivering or causing the tender of gas to Transporter for Shipper's account; or (iii)

that is producing gas ultimately purchased by Shipper for tendering to Transporter. Shipper shall

cause each such entity to provide such actual or estimated data to Transporter upon request in the

normal course of business as soon as such data is available.

(d) Shipper shall furnish to Transporter with its nominations a list, by receipt points,

showing the names and addresses of each entity identified in paragraph (c) above and the name and

telephone number of the contact person who will provide the data required to be furnished pursuant to

paragraph (c) above. Shipper's nominations shall also include (i) the identity of the shipper on any

upstream or downstream pipeline that will be tendering the gas directly to Transporter or taking gas

from Transporter and the shipper's contract number on such upstream pipeline, and (ii) the identity

and gas sales contract number of any producer that will be tendering the gas directly to Transporter.

Such data shall be
