NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

RIGHT OF FIRST OFFER

Section 1.1 Right of First Offer.

(a) At any time and from time to time during the period commencing on the date hereof and continuing until the earlier of (i) such time as this Agreement is terminated in accordance with Section 3.2 below or otherwise and (ii) December 31, 2012 (such period, the "Offer Period"), Landlord will not sell, transfer or otherwise dispose of the Interest (as such term is defined in Exhibit A hereto), or any portion thereof, unless it has first offered to sell the Interest, or such portion thereof, to Subtenant by written notice at an offer price to be set forth therein (the "Initial Offer Price"), which price will be established by Landlord in its sole discretion, together with the material terms and conditions of such proposed disposition by Landlord, including the proposed terms of closing of such disposition, such as the allocation of responsibility to pay closing and title costs (an "Offer"). The Offer shall indicate whether it is for the purchase of the entire Interest in the Premises or a portion thereof (the "Premises Offered").

(b) Subtenant shall have thirty (30) days (the "Acceptance Period") from the delivery of the Offer within which it may (i) deliver to Landlord a notice of its acceptance of the Offer (the "OP Response") and (ii) pay to Landlord, by immediately available federal funds to an escrow account in the name of an escrow agent designated by Landlord ("Escrow Agent"), TWO MILLION DOLLARS ($2,000,000), which shall represent a deposit by Subtenant on account of the purchase pursuant to the Offer (the "OP Deposit"). The OP Response shall not be effective unless it is accompanied with the payment of the OP Deposit.

(c) If the OP Response is effectively and timely delivered, and the Ground Lessor Consent and Ground Lessor Release (each as defined below) shall have been delivered, Landlord shall convey title to the Premises Offered, and Subtenant shall accept and pay for the Premises Offered, at the Initial Offer Price and on the other terms and conditions set forth in the Offer. Time is of the essence of the performance of each of the parties’ respective obligations contained herein. In the event that the sale of the Premises Offered is not consummated solely because either the Ground Lessor Consent or Ground Lessor Release is not delivered (notwithstanding Subtenant’s compliance with Section 1.5), Landlord will promptly cause the Escrow Agent to return the OP Deposit, together with any interest accrued thereon, to Subtenant.

Section 1.2 Failure to Exercise.

(a) If Subtenant (i) fails to deliver the OP Response to Landlord in an effective and timely manner (including payment of the OP Deposit) or (ii) expressly rejects the Offer within the Acceptance Period, then Landlord shall have the right, which shall continue until the first (1st) anniversary of the expiration of the Acceptance Period (said one year period referred to herein as the "First Conveyance Period"), to sell or otherwise dispose of the Premises Offered to any Person free and clear of any obligation to Subtenant pursuant to this Article I, so long as the purchase price to be paid in such sale is an amount equal to at least ninety percent (90%) of the Initial Offer Price and otherwise on terms that are in the aggregate not materially more favorable to the purchaser than those contained in the Offer.

(b) If the purchase price proposed to be paid by a third party for the Premises Offered during the First Conveyance Period is an amount less than ninety percent (90%) of the Initial Offer Price or is otherwise on terms that are in the aggregate materially more favorable to the purchaser than those contained in the Offer, then Landlord shall, by written notice to Subtenant, offer to sell the Premises Offered to Subtenant on the terms proposed with the third party (a "Second Offer"). Upon receipt of the Second Offer from Landlord, Subtenant shall have five (5) Business Days (the "Second Acceptance Period") within which it may notify Landlord in writing of its acceptance of the Second Offer and its agreement to purchase the Premises Offered at the price and on the other terms set forth therein (the "Second OP Response"). The Second OP Response shall not be effective unless it is accompanied with the payment of the OP Deposit.
