Yates - Gas Purchase and Services Amendment for West Kitty

Dan

Yates asked us to prepare amendments to the referenced agreements to include
their West Kitty prospect under the current agreement. (Of course, if its
easier, you could create another document). Here are the particulars:

Reserve Commitment Area -- Section 36 of 51N/74W

Gathering Services Fee = $0.21 per Mcf

Maximum Daily Quantity (MDQ) = 6,000 Mcf/d

Purchase Price (i) baseload IFGMR CIG Index less $0.04
(ii) swing Gas Daily CIG Index less $0.04

Let me know how you would like to proceed (amendment v. separate contract)
and if you need additional info.

Thanks.
