GENERAL TERMS AND CONDITIONS

(Continued)

9. SYSTEM MANAGEMENT

9.1 MRT will at all times maintain operational control of all of its

storage, transmission and other facilities. MRT shall endeavor to preserve

the overall operational integrity of its system; provided, however, that MRT

shall not be obligated to buy or sell gas or to install additional compression

or otherwise modify its system for these purposes. Operating personnel for

Customers and other entities which are physically taking delivery of gas from

MRT or tendering gas to MRT shall cooperate with MRT in furtherance of this

Section 9. Each Customer shall designate one or more persons for MRT to

contact on operating matters at any time, 24 hours a day, every day. If MRT

cannot contact any Customer because that Customer's contact person is

unavailable, such Customer shall be solely responsible for any consequences

arising from such failure of communication.

9.2 For the purpose of this Section 9, the overall operational

integrity of MRT's system shall encompass the integrity of the physical system

and the preservation of physical assets and their performance (including the

capability and deliverability of storage reservoirs), the overall operating

performance of the entire physical system (or any portion thereof), and the

maintenance (on a reliable and operationally sound basis) of adequate system

pressure, total system deliverability and the quality of gas delivered.

9.3 MRT has reserved 30,000 Dth per day of storage deliverability and

the right to recall an additional 70,000 Dth per day of storage deliverability

pursuant to Section 4.8 of Rate Schedule FSS. Such deliverability will be

used to provide no-notice deliveries, instantaneous redelivery of Customer

requirements, proper line pack management, and to cover unintentional daily

imbalances.
