agent shall appoint a single representative to serve on the Advisory

Group. Each shipper or its agent may replace its representative on the

Advisory Group by notice to Administrator. Beginning June 1, 2005, and

annually thereafter, Administrator shall redetermine the top seven

shippers, or their respective agents, for the previous six months ending

April 30 and the membership of the Advisory Group shall be altered

accordingly, if necessary.

settlement calculations hereunder, and adjust such items as necessary to

be representative of the operating parameters of the downstream Plants.
