RESERVE DEDICATION

2.1 Subject to the provisions of Sections 2.4 and 2.5, Shipper hereby agrees to

deliver into and transport through Transporter's pipeline facilities under a

Transportation Agreement under Rate Schedule FT-2, "FT-2 Agreement," or under

Rate Schedule FT-1, "FT-1 Agreement" between Shipper and Transporter all gas

produced by or for the account of Shipper, or any affiliate of Shipper, from the

Committed Lease(s) for the producible life of the Committed Lease(s).

2.2(a) In the event Shipper should transfer or assign any or all of its rights, title

and/or interest in the Committed Lease(s), Shipper agrees that (i) it shall

notify Transporter in writing of its intent of such assignment as soon as

practicable and (ii) any such transfer or assignment will be made subject to the

terms of this Agreement, it being the intent of the parties hereto subject to

the provisions of Article V and this Article II, that the Committed Lease(s)

remain dedicated for purposes of transportation under Rate Schedule FT-2, and/or

Rate Schedule FT-1, to Transporter's pipeline facilities for the producible

life of the Committed Lease(s). All of the provisions of this Agreement shall

be applicable to assignees of Shipper's interests in the Committed Lease(s), and

such assignees shall receive a proportionate assignment of the rights and

obligations hereunder with respect to the Committed Lease(s) so assigned. Upon

such assignment, Shipper shall be relieved of its obligations under this

Agreement to the extent, and only to the extent, such obligations are assigned

to a third party.

(b) Shipper shall be entitled to unitize any Committed Lease(s) with one or more

additional OCS leases without the consent of Transporter. In the event of such

unitization, then (i) such unitization shall not be deemed a transfer or

assignment of Shipper's interest for the purpose of this Agreement and (ii) only

the gas production attributable to Shipper's interest in the unit shall be

subject to the provisions of this Agreement or be entitled to the services

provided by the associated FT-2 Agreement. For purposes of this Section 2.2

(b), "unitize" or "unitization" shall mean the combination of all or parts of

the leases in a prospect, reservoir, or field such that development and

operation of the unit are provided
