f. Shipper or its affiliate has committed the Committed Production to

Transporter for Transportation under this Rate Schedule and

satisfactorily submits documentation establishing P-50 reserves of

the Committed Production within eighteen (18) Months after

committing the Committed Production. Shipper's MDVQ-Mainline and

MDVQ-Expansion established in accordance with Subsection 2.a. of

this FT-2 Rate Schedule for service, based on Shipper's good faith

estimate before the Committed Production is documented, will not

be increased as a result of such documentation unless firm

capacity is available at that time.

g. A Shipper with an Effective FT-2 Service Agreement may request an

increase of its MDVQ-Mainline or MDVQ-Expansion if the estimated

or proven amount of its Committed Production increases as the

result of documentation, or drilling additional wells or acquiring

additional Gas production rights in the blocks, lands and leases

dedicated to Transporter and described in Shipper's Effective FT-2

Service Agreement. Shipper must submit a written request for an

increase of its MDVQ-Mainline or MDVQ-Expansion in accordance with

Section 4 of Transporter's FERC Gas Tariff, and capacity will be

awarded in accordance with Section 2 of Transporter's FERC Gas

Tariff.

2. APPLICABILITY AND CHARACTER OF SERVICE

a. Transportation under this Rate Schedule is limited to Committed

Production as described in Shipper's Effective FT-2 Service

Agreement and is further limited to the MDVQ-Mainline or MDVQ-

Expansion, as defined in this Subsection 2.a.

Shipper's MDVQ-Mainline and MDVQ-Expansion for Transportation

service provided before Shipper satisfactorily documents the

Committed Production will be an amount equal to Shipper's good

faith estimate of the Committed Production divided by two thousand

nine hundred and twenty (2920). This amount will be prorated,

based on the number of Days the FT-2 service is in effect prior to

the recalculation date, which will be January 1 of each Year.

Thereafter, the MDVQ-Mainline and MDVQ-Expansion will be

determined by subtracting the quantities of Gas shipped during the

previous Contract Year from the Committed Production
