On May 20, 2011 (the “Closing Date”), TNP Strategic Retail Trust, Inc.

The Company paid Lender $4,268,316 in connection with the Repayment, which included the repayment of the aggregate principal amount outstanding plus all accrued and unpaid interest. The Northgate Loan is designated as a borrowing under the A tranche of the Credit Agreement and bears interest at a variable rate of 5.50% per annum pursuant to the terms of the Credit Agreement. The entire unpaid principal balance of the Northgate Loan and all accrued and unpaid interest thereon is due and payable in full on December 17, 2013, subject to extension to December 17, 2014 pursuant to the terms of Credit Agreement.

TNP SRT Northgate Plaza Tucson, LLC, an indirect subsidiary of the Company and the direct owner of the Northgate Property (“TNP SRT Northgate”), entered into a Joinder Agreement with KeyBank whereby TNP SRT Northgate agreed to become a party to the Credit Agreement as a Borrower (as defined in the Credit Agreement). TNP SRT Northgate also entered into a Deed of Trust, Assignment of Rents, Security Agreement and Fixture Filing made for the benefit of KeyBank with respect to the Northgate Property for purposes of securing the Borrower’s obligations under the Credit Agreement.
