Revised TC language if EPMI is Buyer in ERCOT across DC tie

__________________

I have discussed with Doug Gilbert-Smith the transmission contingent language
e-mailed to you on 4-27-01 and am communicating the revised text below for
insertion into those written confirmations of EPMI's purchases in ERCOT being
supplied across a DC tie, when designated by the ERCOT traders to require
this insert . This text is only for those specific transactions which the
ERCOT traders indicate.

"Transmission Contingent: DC Tie. If Seller is unable to secure the
transmission required for this Transaction on a DC tie line across the ERCOT
system border ("DC tie"), or transmission on such DC tie is curtailed in a
manner affecting Seller's delivery hereunder, then Seller at its election
shall not be required to deliver the affected portion of the Energy and, in
the event of that election by Seller, neither party shall be liable to the
other hereunder for failure to deliver/receive such Energy. No other
transmission contingency is designated by the parties to pertain to this
Transaction."
