      Pipeline shall not be obligated to, but may at its discretion, receive at
any Point of Receipt on any day a quantity of gas in excess of the applicable
Maximum Daily Receipt Obligation (MDRO), plus Applicable Shrinkage, but shall

                                   ARTICLE II

shall continue in force and effect until 10/31/1999 and year to year thereafter
unless this Service Agreement is terminated as hereinafter provided. This

                             FOR RATE SCHEDULE FT-1
                                   (Continued)

prejudice to such rights, this Service Agreement may be terminated at any time
by Pipeline in the event Customer fails to pay part or all of the amount of any
bill for service hereunder and such failure continues for thirty (30) days after
payment is due; provided, Pipeline gives thirty (30) days prior written notice
to Customer of such termination and provided further such termination shall not
be effective if, prior to the date of termination, Customer either pays such
outstanding bill or furnishes a good and sufficient surety bond guaranteeing
payment to Pipeline of such outstanding bill.

      THE TERMINATION OF THIS SERVICE AGREEMENT WITH A FIXED CONTRACT TERM OR
THE PROVISION OF A TERMINATION NOTICE BY CUSTOMER TRIGGERS PREGRANTED
ABANDONMENT UNDER SECTION 7 OF THE NATURAL GAS ACT AS OF THE EFFECTIVE DATE OF
THE TERMINATION. PROVISION OF A TERMINATION NOTICE BY PIPELINE ALSO TRIGGERS
CUSTOMER'S RIGHT OF FIRST REFUSAL UNDER SECTION 3.13 OF THE GENERAL TERMS AND

with processing of such gas as necessary to comply with such quality
specifications. Customer shall execute or cause its supplier to execute, if such
supplier has retained processing rights to the gas delivered to Customer, the
appropriate agreements prior to the commencement of service for the
transportation and processing of any liquefiable hydrocarbons and any PVR
quantities associated with the processing of gas received by Pipeline at the
Point(s) of Receipt under such Customer's service agreement. In addition,

and charges applicable to service pursuant to Pipeline's Rate Schedule FT-1, (b)
Pipeline's Rate Schedule FT-1 pursuant to which service hereunder is rendered or
(c) any provision of the General Terms and Conditions applicable to Rate
