NOW THEREFORE, for and in consideration of the mutual promises, covenants and agreements hereinafter contained to be kept and performed by the parties hereto and upon the provisions and conditions hereinafter set forth, Authority and Tenant do hereby covenant and agree, and each for itself does hereby covenant and agree, as follows:

SECTION 1.  Definitions.  Except as otherwise provided herein, and unless the context shall clearly require otherwise, all words and terms used in this Twenty–Seventh Supplemental Lease Agreement which are defined in the Lease Agreement, shall, for all purposes of this Twenty-Seventh Supplemental Lease Agreement, have the respective meanings given to them in the Lease Agreement.

SECTION 2.  Granting of Leasehold.  In addition to the lease and demise to Tenant of the land in the Lease Agreement, the Authority hereby leases and demises to Tenant, and Tenant hereby takes and hires from Authority, subject to the provisions and conditions set forth in the Lease Agreement and this Twenty-Seventh Supplemental Lease Agreement, the additional land described in Exhibit “A” attached hereto and containing approximately 187,618 square feet or 4.31 acres, and described in Exhibit “B” attached hereto containing approximately 106,642 square feet or 2.448 acres.

SECTION 3.  Term; Delivery and Acceptance of Possession.  The term of this Twenty-Seventh Supplemental Lease Agreement and all rights herein granted to tenant shall be made effective as of May 1, 2006 for the land  described in Exhibits “A” and  “B” and shall expire at such time as the Consolidated and Restated Lease Agreement dated August 1, 1979 shall expire, to-wit:  August 31, 2012 or upon such earlier termination, extension or otherwise as provided therein.

SECTION 4.  Rental.   In addition and supplemental to the rentals required to be paid to the Authority pursuant to Section 5 of the Lease Agreement (including all prior Supplemental Lease

4

Agreements), during the term of this Twenty-Seventh Supplemental Lease Agreement, Tenant shall pay equal rental installments to the Authority in advance on the first business day of each month beginning on the earlier of  the date of beneficial occupancy or the following dates, to wit:

The rental rate shall adjust upward by twenty-five percent (25%) every five (5) years in accordance with the Base Lease Agreement.

SECTION 5.  Hazardous Substances/Waste.  Tenant agrees to take the above parcels included in this Supplement in an “as is” condition as it relates to Hazardous Substances/Waste material that may be located at the site.

Tenant, at its own expense, may arrange for a Phase I Environmental Survey on the land described herein by a reputable environmental consultant to determine the existence of “Hazardous Substances”, as such term is defined in this Agreement. In the event that “Hazardous Substances” are discovered during excavation for construction on the property described in Exhibits “A” & B, and those “Hazardous Substances” require special handling, removal or disposal (“Remediation”), then Tenant shall immediately notify Authority. The Tenant and Authority will confer and jointly determine the method of handling, removing or disposing of the “Hazardous Substances” within 14 days after Tenant provides the Authority, in writing, its plan for Remediation. The form of Remediation agreed to by the parties must comply with “Environmental Laws”, as such term is defined below. In the event that Tenant and Authority are unable to agree on a method for handling, removing or disposing of the “Hazardous Substances” due to differing interpretations of the

5

requirements for Remediation as set forth in the applicable “Environmental Laws”, then the form of Remediation will be determined by the appropriate federal, state or local agency with relevant regulatory and enforcement jurisdiction over the subject site. Authority will grant to Tenant a rent credit equal to the reasonable documented costs paid by Tenant for the Remediation of such “Hazardous Substances” associated with the property described in Exhibits “A” & “B”.

The term “Hazardous Substances”, as used in this Twenty-Seventh Supplemental Lease Agreement, shall mean any hazardous or toxic substances, materials or wastes, including, but not limited to, those substances, materials, and wastes (i) listed in the United States Department of Transportation Hazardous Materials Table (49 CFR § 172.101) or by the Environmental Protection Agency as hazardous substances (40 CFR Part 302 and amendments thereto), (ii) designated as a “Hazardous Substance” pursuant to Section 311 of the Clean Water Act, 33 U.S.C. § 1251 et seq. (33 U.S.C. § 1321) or listed pursuant to Section 307 of the Clean Water Act (33 U.S.C. § 1317), (iii) defined as a “Hazardous Waste” pursuant to Section 1004 of the Resource Conservation and Recovery Act, 42 U.S.C. § 6901, et seq. (42 U.S.C. § 6903), or (iv) defined as “Hazardous Substance” pursuant to Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act, (42 U.S.C.§ 9601, et seq. 42 U.S.C. § 9601), or any other substances, (including, without limitation, asbestos and raw materials which include hazardous constituents), the general, discharge or removal of which or the use of which is restricted, prohibited or penalized by any “Environmental Law”, which term shall mean any Federal, State or local law, regulation, or ordinance relating to pollution or protection of the environment.

SECTION 6.  Lease Agreement Still in Effect; Provisions Therefore Applicable to this Supplemental Lease Agreement.  All of the terms, provisions, conditions, covenants and agreements of the Lease Agreement, as supplemented, shall continue in full force and effect as

SECTION 7.  Descriptive Headings.  The descriptive headings of the sections of this Twenty-Seventh Supplemental Lease Agreement are inserted for convenience of reference only and do not constitute a part of this Twenty-Seventh Supplemental Lease Agreement and shall not affect  meaning, construction, interpretation or effect of this Twenty-Seventh Supplemental Lease Agreement.
