2012 Credit Facility

In November 2012, we entered into a $1.6 billion credit facility, or the 2012 credit facility, which refinanced, extended and upsized the previous 2011 revolving credit facility. The 2012 credit facility consists of a $1.2 billion revolving credit facility, or the revolving credit facility, and a $400.0 million term loan, or the term loan facility. The revolving credit facility matures in March 2017 and includes two six-month extension options, subject to certain conditions and the payment of an extension fee of 10 basis points for each such extension. We also have an option, subject to customary conditions, without the consent of existing lenders, to increase the capacity under the revolving credit facility to $1.5 billion at any time prior to the maturity date for the revolving credit facility, by obtaining additional commitments from our current lenders and other financial institutions. The term loan facility matures on March 30, 2018.

The 2012 credit facility bears interest at a spread over LIBOR ranging from (i) 100 basis points to 175 basis points for loans under the revolving credit facility and (ii) 115 basis points to 200 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. At March 31, 2013, the applicable spread was 145 basis points for revolving credit facility and 165 basis points for the term loan facility. We are required to pay quarterly in arrears a 15 to 35 basis point fee on the unused balance of the commitments under the revolving credit facility. As of March 31, 2013, the facility fee was 30 basis points. At March 31, 2013, we had approximately $91.9 million of outstanding letters of credit, $30.0 million borrowings under the revolving credit facility and $400.0 million outstanding under the term loan facility, with undrawn capacity of $1.2 billion under the 2012 credit facility.

We, ROP and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. No other subsidiary of ours is an obligor under the 2012 credit facility.

The 2012 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

2011 Revolving Credit Facility

The 2012 credit facility replaced our $1.5 billion revolving credit facility, or the 2011 revolving credit facility, which was terminated concurrently with the entering into the 2012 credit facility. The 2011 revolving credit facility bore interest at a spread over LIBOR ranging from 100 basis points to 185 basis points, based on the credit rating assigned to the senior unsecured long term indebtedness of ROP, and required us to pay quarterly in arrears a 17.5 to 45 basis point facility fee on the total commitments under the 2011 revolving credit facility. The 2011 revolving credit facility included certain restrictions and covenants and, as of the time of the termination of the 2011 revolving credit facility and as of November 2012, we were in compliance with all such restrictions and covenants.

Restrictive Covenants

The terms of the 2012 credit facility and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the minimum amount of tangible net worth, a maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that we will not during any time when a default is continuing, make distributions with respect to common stock or other equity interests, except to enable us to continue to qualify as a REIT for Federal income tax purposes. As of March 31, 2013 and December 31, 2012, we were in compliance with all such covenants.

Junior Subordinate Deferrable Interest Debentures

In June 2005, we issued $100.0 million in unsecured floating rate trust preferred securities through a newly formed trust, SL Green Capital Trust I, or the Trust, which is a wholly-owned subsidiary of the Operating Partnership. The proceeds from the security offering were transferred to the Operating Partnership as a loan. The securities mature in 2035 and bear interest at a fixed rate of 5.61% for the first ten years ending July 2015. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises its right to defer such payments. The trust preferred securities are redeemable, at the option of the Operating Partnership, in whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our balance sheet and the related payments are classified as interest expense.
