reconstructed or added to is used or useful for the generation of electrical
power and energy, or to the end of the period permitted by Applicable Law,
whichever first occurs, the Buyer waives its right to partition whether by
partition in kind or sale and division of the proceeds thereof, and agrees that
it will not resort to any action at law or in equity to partition and further
waives the benefit of all laws that may now or hereafter authorize such
partition of the properties compromising the Facility. It is agreed that this
covenant shall be deemed to run with the land. The Buyer agrees to incorporate
this waiver in all deeds, deeds of trust, mortgages and instruments of
conveyance relating to the Undivided Interest or any interest or portion
thereof, whether delivered at the Closing or thereafter.
