On November 20, 2012, Mack-Cali Realty, L.P. (the “Company”), the operating partnership of Mack-Cali Realty Corporation (the “General Partner”), completed the sale of $250 million of senior unsecured notes (the “Notes”). The Notes were priced on November 13, 2012, mature on December 15, 2017 and bear interest at 2.500%, with interest payable semiannually on June 15 and December 15 of each year outstanding, beginning on June 15, 2013.  The Company received net proceeds of approximately $246.3 million from the sale of the Notes which are intended to be used  for general corporate purposes and working capital, which will include the repayment of  substantially all outstanding borrowings under the Company’s unsecured revolving credit facility and may include the purchasing or retiring of some of the Company’s outstanding debt securities.  The Company may redeem the Notes at any time upon payment of a make-whole amount.

The Notes are being issued under an indenture dated as of March 16, 1999 (the “Indenture”) by and among the Company, as issuer, the General Partner, as guarantor, and Wilmington Trust Company, as trustee (the “Trustee”), as supplemented by supplemental indenture no. 16 dated as of November 20, 2012 (the “Supplemental Indenture”) by and between the Company and Trustee.  The material terms of the Indenture, as amended by the Supplemental Indenture, provide for the issuance of the Notes on the terms set forth in the preceding paragraph and include certain representations, warranties and covenants, conditions to closing and other obligations of the Company, the General Partner and the Trustee that are customary in an underwritten public offering, including those terms and conditions made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended.
