WHEREAS, Seller and Buyer wish to amend the Agreement as set forth in this Addendum.

FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES SET FORTH IN THIS ADDENDUM AND OTHER GOOD AND VALUABLE CONSIDERATION, THE RECEIPT AND SUFFICIENCY OF WHICH ARE HEREBY ACKNOWLEDGED, BUYER AND SELLER AGREE AS FOLLOWS:

1.     Words and phrases defined in the Agreement have the same meaning when used in this Addendum unless otherwise indicated. In the event of any conflict between the terms and provisions of this Addendum and the terms and provisions of the Agreement, the terms and provisions of this Addendum shall control. When fully executed, this Addendum shall become part of the Agreement.

2.     The Purchase Price is hereby increased by Five Hundred Thousand Dollars ($500,000.00) to a total of Twenty Three Million Five Hundred Thousand Dollars ($23,500,000.00).

3.     Buyer and Seller agree to extend the Examination Period until 5:00 p.m. Eastern Time (as then in effect) on March 22, 2019.

4.     The “Closing Date” shall be the date that is forty-five days after the expiration of the Examination Period as extended under Section 3 of this Addendum.

5.     During the Examination Period (as extended under this Addendum), Seller may solicit and receive offers for the purchase of all or part of the Property on such terms as Seller may determine in its sole discretion. If Seller receives an offer that Seller intends to accept (an “Offer”), then Seller shall give Buyer written notice of Seller’s intent to accept the Offer. Within five (5) Business Days after Seller has notified Buyer of Seller’s intent to accept the Offer, Buyer shall have the right to waive the balance of the Examination Period and deliver to Seller an Approval Notice, in which case the Earnest Money shall become immediately non-refundable (except only if this Agreement is terminated as a result of Seller’s default under the Agreement). If Buyer fails to waive the Examination Period and send an Approval Notice, the Seller upon written notice to Buyer may terminate this Agreement, in which case the provisions of Section 8 of the Original Contract (including those pertaining to the return of the Earnest Money) shall apply as if Buyer had delivered a Termination Notice; and Buyer’s escrow shall immediately be released back to Buyer.
