WHEREAS, Landlord and Tenant have heretofore entered into that certain Lease Agreement dated as of February 8, 2006 (the " Lease Agreement "); and

WHEREAS, Landlord and Tenant amended the Lease Agreement pursuant to the terms and conditions of that certain First Amendment to Lease Agreement dated as of August 8, 2006 but effective as of June 15, 2006 (the " First Amendment ");

WHEREAS, Exhibit F to the Lease Agreement provides, among other things, that in the event that certain Scope Changes (as defined in Exhibit F to the Lease Agreement) occur, either (a) Base Rent (as defined in the Lease Agreement) will be adjusted as provided for in Exhibit F, or (b) Tenant shall have the right to fund all or such portion of such excess costs in which case Base Rent will not be adjusted as a result of such Tenant expenditures; and

WHEREAS, certain Scope Changes have occurred in addition to those contemplated by the First Amendment (such additional scope changes being herein referred to as the "Second Amendment Scope Changes") as hereinafter set forth, and Landlord and Tenant desire to provide for the funding of the Second Amendment Scope Changes.

A G R E E M E N T:

NOW, THEREFORE, for and in consideration of the premises and Ten Dollars and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

1. Defined Terms . All capitalized but undefined terms used in this Amendment shall have the meaning given such terms in the Lease Agreement.

2. Nature of Scope Changes . The Second Amendment Scope Changes are as follows:

a. Second Amendment Additions to Tenant Finish . As a result of the development of the Final Tenant Improvement Plans and Specifications provided for by Section 2(d) of the Lease Agreement, and based upon the Merriman Schmitt drawings noted in Exhibit A (attached hereto) and the September 1, 2006 Choate estimate, the final estimated amount of the Tenant Improvement Costs submitted by Choate is $6,048,543, which is $1,192,825 in excess of the $4,855,718 Tenant Allowances provided therefor in the First Amendment; provided, however, that the following amounts have not been approved by Tenant and are still in dispute between Tenant and Landlord (collectively, the "Disputed Second Amendment Amounts"):








Choate GC92s $ 83,855
Re-mob HVAC $ 21,716
HVAC Redesign $ 27,206
Re-mob Drywall $ 27,486
Electrical Design Engineering $ 20,000
Credit back plywood $ 2,379
Credit for electric strikes $ 6,400
Omit gas grill $ 11,336
Omit site/web cam $ 1,644

Subtotal $ 202,022




Thus, the final estimated amount of the Tenant Improvement Costs not in dispute by the parties is $5,893,727 ($6,048,543 - $202,022 = $5,846,521), and which results in an increase of $909,803 above the $4,855,718 Tenant Allowances provided therefor in the First Amendment (the amount of such increase being herein referred to as the "Second Amendment Additions to Tenant Finish").

3. Funding of Second Amendment Scope Changes . Tenant agrees to pay for the Second Amendment Additions to Tenant Finish as defined in paragraph 2 above as follows: Landlord is in the process of constructing the portions of the Tenant Improvements that include the Second Amendment Additions to Tenant Finish. Tenant will pay Landlord for the amount of the Second Amendment Additions to Tenant Finish on a monthly basis as Landlord incurs such costs. Landlord will submit to Tenant within fifteen days after the last day of each calendar month a Certificate for Payment indicating the amount of the expense that the Landlord has incurred during such month for Second Amendment Additions to Tenant Finish, and Tenant shall pay Landlord for such amounts as shall have been incurred in accordance with the Final Tenant Improvement Plans and Specifications on or before ten (10) business days after Tenant92s receipt of such Certificate for Payment; provided that, unless otherwise agreed by the Tenant, the aggregate amount of the actual increases to Tenant Improvements expenses billed to the Tenant pursuant to the First Amendment and this Second Amendment (not including the Disputed Second Amendment Amounts, which remain in dispute between the parties) shall not exceed $3,007,521. To the extent that Tenant and Landlord agree in writing to changes to the Merriman Schmitt drawings (see Exhibit A attached hereto) and the cost of such changes, and it causes increases above the foregoing aggregate $3,007,521 Additions to Tenant Finish pursuant to the First Amendment and this Second Amendment, Tenant will be responsible for such increase; and the parties agree that the Disputed Second Amendment Amounts remain in dispute and that the ultimate resolution of such items under the terms of the Lease may also affect the final amount of the Tenant Improvement Costs.

4. Failure of Tenant to Pay for Second Amendment Additions to Tenant Finish . Tenant92s failure to make any payment due for Second Amendment Additions to Tenant Finish under paragraph 3 above when due and the continuance of that failure for more than 5 business days after the date on which Landlord gives Tenant written notice of the delinquency shall constitute an Event of Default under the Lease Agreement.

5. Treatment of Tenant92s Payments for Second Amendment Scope Changes . Consistent with the last paragraph of Exhibit F of the Lease Agreement, the Second Amendment Additions to Tenant Finish made pursuant to this Amendment and any payments made by the Tenant pursuant to this Amendment shall not result in any adjustment to Rent under the Lease Agreement or be included in the Project Costs determined pursuant to the Lease Agreement. The Second Amendment Additions to Tenant Finish shall be deemed to be Alterations approved by the Landlord, and the amounts therefor billed to Tenant pursuant to
