operations of the Partnership, except to the extent specifically provided

the fair market value of any such assets shall be determined by NELP IV in its
reasonable discretion. Developer agrees that if there is any dispute or
disagreement regarding any sale pursuant to this paragraph (g), including,
without limitation, the determination of the fair market value of the assets
