EXPLANATION OF RESPONSES:
- ------------------------

(1)  The Enron Disputed Claims Reserve (the "DCR") is a distribution mechanism
     created pursuant to Section 21.3(a) of the Fifth Amended Joint Plan of
     Affiliated Debtors Pursuant to Chapter 11 of the United States Bankruptcy
     Code, In re Enron Corp., et al., including, without limitation, the Plan
     Supplement and the exhibits and schedules thereto (the "Plan"). The purpose
     of the DCR is for the disbursing agent, Stephen Forbes Cooper, LLC, or its
     successor (the "Disbursing Agent"), to hold in escrow for the benefit of
     the holders of allowed claims 35,463,555 shares of Portland General
     Electric Company common stock (the "Shares"), cash, certain trust interests
     and other securities and any dividends, gains or income attributable
     thereto, to be issued periodically to holders of allowed claims as disputed
     claims are resolved pursuant to the Plan. Neither the Disbursing Agent nor
     the DCR have any pecuniary interest in the Shares. The Disbursing Agent may
     only vote and sell the Shares as record holder of such securities pursuant
     to the instructions of, or upon the prior approval of, the DCR Overseers.
     The DCR Overseers consist of John J. Ray III, Rick A. Harrington, James R.
     Latimer III, Stephen D. Bennett and Robert M. Deutschman and each of them
     disclaim any interest in the Shares.
