   3

If, at any time after the second anniversary date of the In-Service Date (but
prior to the tenth anniversary date of the In-Service Date), there is
insufficient Available Production to fill Shipper's MDQ, then Shipper shall
have the one-time option to reduce the MDQ under this Agreement to the level of
Available Production. To exercise such option, Shipper shall provide
Transporter with 60 days' prior written notice and shall pay Transporter the
prepaid reservation charges (PRC) amount described below. "Available
Production" means the monthly average daily volume of gas produced from the
leases and lease positions owned, hereafter acquired or controlled by
operation, by Shipper or a Shipper affiliate in the geographic area described
on Exhibit "C" hereto, excluding lease use gas, line loss, and gas used as
gathering fuel. Notwithstanding anything to the contrary in this Agreement,
Shipper shall have the full and complete right to determine when and to what
extent such leases and lease positions will be developed and gas produced
therefrom.

    In the event Shipper elects to reduce the MDQ under this Agreement pursuant
    to the provisions of the paragraph above, the PRC amount shall equal the 
    result of the following formula:

                    [16,000 - X]    Where X = the new MDQ (in Dth/day) under
       $6,400,000 x ------------    this Agreement, after reduction by Shipper
                       16,000
             
             

10. TERMS OF AGREEMENT:    The term of this Agreement shall commence on the
                           first of the month following the In-Service Date of
                           the Cucharas Lateral and shall remain in effect for
                           12 years thereafter. However, each incremental
                           increase in MDQ shall be effective for a period of
                           10 years as shown in paragraph 9.

                                  EXHIBIT "B"

NOTES: (1)  (a) Except as provided in subparagraph (b) below, the rate for
                service under this Agreement ("Fixed Rate") shall be 32.50
                cents per Dth (computed on a 100 percent load factor basis),
                plus fuel, L&U, GRI, if applicable, and ACA and all other
                surcharges applicable to Transporter's Rate Schedule TF-1.
                Should Transporter's Maximum Rate as defined below, when
                computed on a 100% load factor basis exceed 32.50 cents per Dth
                except as provided in subparagraph (b) below, the Fixed Rate
                shall nevertheless be applicable. Should Transporter's Maximum
                Rate or rate components be set at a level such that Transporter
                is unable to collect the Fixed Rate, then Shipper agrees to an
                increase in the MDQ or to other lawful arrangements, such that
                the Parties are placed in the same economic position as if
                Transporter had collected the Fixed Rate.

            (b) Transporter and Shipper agree that no reserve dedication, well
                dedication, or acreage dedication exists. However, Transporter
                is agreeing to the Fixed Rate in recognition of Shipper's
                agreement to tender to Transporter for transportation under
                this Agreement: (i) all Available Production (other than Local
                Consumption) up to the MDQ volume set forth in paragraph 9; and
                (ii) only Available Production. For any period of time in which
                Shipper fails to satisfy both conditions (i) and (ii) above, at
                Transporter's option, the rate for service under this Agreement
                shall be the ten-effective maximum reservation and commodity
                rates for firm transportation service under Transporter's Rate
                Schedule TF-1, plus fuel, L&U, GRI (if applicable), ACA, and
                all other surcharges applicable to Transporter's Rate Schedule
                TF-1 ("Maximum Rate"). "Local Consumption" means a volume of
                Available Production which Shipper delivers from its gathering
                system for local consumption.
