FAQ Continued

• Q Does the recent extension on the Investment
  Tax Credit through 2008 effect the project
  timing?
• A PSE continues its desire for a project that
  meets substantial and final completion in 2007.
  If there are significant reasons why a Contractor
  feels a 2008 project is advantageous, a bid for a
  2008 project may be submitted.
• Q If a PPA is offered, will rent be charged by
  PSE for use of the land?
• A If a PPA is offered, it shall assume that PSE
  will offer a nominally priced lease for the
  20-year life of the project (e.g. 1 for a 20
  year lease).
