or materialmen) any of the aforementioned persons may incur as a result of
Purchaser’s or Purchaser’s agents’ or contractors’ activities on the Property
under this Article 3. The indemnity obligations of Purchaser under this

any of the Land or Improvements, describing such damage, stating whether such
damage and loss of rents is covered by insurance and the estimated cost of
repairing such damage. In the event of any “material damage” (described below)
to any of the Land or Improvements, Purchaser may, at its option, by notice to
Seller given within ten (10) business days after Seller has provided the above
described notice (and if necessary the Closing Date shall be extended to give
Purchaser the full ten (10) business day period to make its election):
(i) terminate this Agreement, in which case the Earnest Money shall be
immediately delivered to Purchaser; or (ii) proceed under this Agreement,
receive any insurance proceeds (including any rent loss insurance applicable to
any period on and after the Closing Date) due Seller as a result of such damage
and receive a credit at Closing for any deductible amount under said insurance
policies. If Purchaser fails to timely make such election, Purchaser shall be
deemed to have elected to terminate this Agreement. If any of the Land or
Improvements is not materially damaged, then (i) Purchaser shall not have the
right to terminate this Agreement and (ii) at Closing, Purchaser shall receive
any insurance proceeds (including any rent loss insurance applicable to any
period on and after the Closing Date) due Seller as a result of such damage and
receive a credit at Closing for any deductible amount under said insurance
policies. “Material damage” and “materially damaged” means, with respect to any
Improvements, damage that: (a) in Purchaser’s reasonable estimation, exceeds

written notice to Purchaser of such proceedings together with all relevant

be extended to give Purchaser the full ten (10) business day period to make such
election): (i) terminate this Agreement, in which case the Earnest Money shall
be immediately delivered to Purchaser, or (ii) proceed under this Agreement, in
which event Seller shall, at the Closing, assign to Purchaser its entire right,
title and interest in and to any condemnation award, and Purchaser shall have
the sole right during the pendency of this Agreement to negotiate and otherwise
deal with the condemning authority in respect of such matter. If Purchaser fails
to timely make such election, Purchaser shall be deemed to have elected to
terminate this Agreement as provided above. “Material Condemnation” means, with
respect to any of the Land or Improvements, condemnation by eminent domain which
in Purchaser’s reasonable estimation materially and adversely affects the use,
operation or value of any property comprising the Land and Improvements.
