FIRM CAPACITY MDQ

MMBTU/D

(AS AMENDED EFFECTIVE AS OF DECEMBER 1, 2009)

Time Period		MDQ
Effective Date through 11/30/09			100,000
12/01/09 though 11/30/10			130,000
12/01/10 though 11/30/11			130,000
12/01/11 though 11/30/12			130,000
12/01/12 though 11/30/13			75,000

Gatherer will use commercially reasonable efforts to provide Shipper its Firm Capacity MDQ as described above in 2009 – 2012 of 130,000 MMBTU/D. Should Gatherer discover its pipeline capacity cannot fulfill Firm Capacity MDQ as described above because of Gatherer’s physical limitations (not because of commitments to any other shippers except for commitments of 1000 MMBTU/D to another shipper), the MDQ through 11/30/2012 shall thereafter be reduced to actual (subject to other shipper commitment) with other MDQ amounts unchanged and no refund obligation.
