(i) Pursuant to Section 284.10 of the Commission's

regulations, Transporter's firm sales customers have certain

rights to convert a portion of their Contract Demand under

firm sales agreements to firm transportation. Transporter

shall first make available any available firm capacity to

any firm sales customer electing to convert some portion of

its Contract Demand. Notwithstanding the notice provisions

of Section 284.10 of the Commission's regulations,

Transporter's firm sales customers shall notify Transporter

of firm sales customer conversion elections and submit a

valid request for firm transportation service reflecting

such conversions within thirty (30) days from the date

Transporter stipulates in its public notice that it is

accepting requests for transportation service hereunder.

Subject to the conditions contained in Section 3.3 hereof

and Section 12 of the General Terms and Conditions, such

conversions shall become effective on the first day of the

third calendar month following the end of the aforementioned

thirty (30) day period. Subject to the conditions contained

in Section 3.3 hereof and Section 12 of the General Terms

and Conditions, on or before February 1, 1990, and on or

before February 1 of each year thereafter, Transporter shall

be notified of firm sales customer conversion elections made

pursuant to Section 284.10 of the Commission's regulations.

Such conversions shall become effective on April 1 of each

year. Transporter and Shipper shall execute a firm

Transportation Service Agreement with respect to any

conversion to a firm transportation contract quantity on or

before the date such conversion becomes effective.

Concurrently, Shipper and Transporter shall execute a

revised sales service agreement to reflect a reduction in
