to shut in wells and to renew, surrender, release or

terminate any lease (in whole or in part) included in the

Committed Lease(s);

(b) The right to deliver production to lessors of the Committed

Leases in quantities sufficient to fulfill Shipper's lease

obligations from time to time, including the right to

deliver royalty in kind; and

operation of the Committed Lease(s), including, but not

limited to, the use of gas for fuel, drilling

(including gas drilling), deepening, reworking, development

system installation and startup, compressing, gas lifting,

processing, treating, cycling, repressuring or other

supplemental recovery operations, provided, however, that

any gas so used but not consumed by such uses shall remain

committed under this Agreement.

(d) The right to process gas from the Committed Lease(s), prior

to delivery to Transporter, by the use of mechanical

separators for the recovery of any component from the gas

other than methane, except such methane incidentally removed

through such separation.
