Adverse Notice Error, the Allocated Value shall be used. If the transfer of the
Asset occurs after the Cut-Off Date, the applicable Seller shall promptly refund
to Purchaser such amount in lieu of an adjustment under Section 2.3(b). For
purposes of this Section 3.6, “Adverse Notice Error” means that Sellers have
sent a notice to the holder of the applicable preferential right to purchase or
similar right that states an Allocated Value for the affected Assets that is
less than that provided by Schedule 3.4.

the case of subleases, assignment shall not be permitted without the prior
written consent of DEPI, such consent not to be unreasonably withheld, and in

at Purchaser’s expense, provided that Purchaser may only settle such demand or
proceedings with the prior written consent of DEPI, such consent not to be
unreasonably withheld.
