ARTICLE I

Definitions

1.1           The recitals are specifically incorporated into the body of this Agreement and shall be binding upon the parties hereto.

1.2           Unless expressly set forth to the contrary and except as modified by this Agreement, all capitalized or defined terms shall have the meanings ascribed to them in the Lease.

ARTICLE II

Lease Modifications

2.1           Effective as of March 17, 2007 (the “Effective Date”), the Lease is and shall be modified and amended as follows:

2.1.1                      Rent.  Article 2.1.4 of the Second Amendment to Lease is hereby modified and amended by inserting the following:

“Notwithstanding anything to the contrary set forth herein, provided Tenant is not in default under the Lease, Tenant shall receive a fixed rent credit equal to the amount Tenant pays for the premium for the required property insurance pursuant to Section 2.1.2 hereof. Tenant shall submit a paid-in-full invoice for said premium to Landlord and Landlord shall credit such amount towards the next month’s fixed rent that is due and payable under the Lease.”

2.1.2                      Insurance.  Paragraph 55(a) of the Rider to the Lease is hereby modified and amended by inserting the following:

“Throughout the term of the Lease, Tenant shall obtain and maintain in full force and effect property insurance against hazards covered by an all risk coverage insurance policy (including fire, extended coverage, vandalism, malicious mischief and sprinkler leakage) as Landlord may reasonably, from time to time, require, covering the Premises, including the Building, all improvements constructed thereon and fixtures and equipment, stock in trade, furniture, furnishings and other personal property located on or about the Building to the extent of their full insurable value but in any event in an amount sufficient to prevent Tenant from becoming a co-insurer under provisions of applicable policies. For all purposes of this Lease, “full insurable value” means the actual replacement cost of the Building without physical depreciation and said “full insurable value” shall be determined at the request of Landlord by an architect, appraiser, or appraisal company, selected and paid by Tenant and reasonably acceptable to Landlord.”
