FINANCIAL RESULTS

NEW YORK, NY, OCTOBER 25, 1999 - SL Green Realty Corp. (NYSE:SLG) reported
improved results for the three and nine months ended September 30, 1999. Funds
from operations (FFO) before minority interest totaled $15.9 million, or $0.58
per share, based on 31.4 million shares and common share equivalents
outstanding. This compares to $12.6 million, or $0.48 per share for the same
quarter in 1998.

Revenues for the third quarter were $54.7 million compared to $39.8 million in
the same period last year - an increase of 37%. Revenue growth was derived
from $2.5 million in new leasing activity, $1.3 million from other real estate
incentives and fee based business and $11.1 million from normalization of 1998
and 1999 acquisitions.

The 1999 "same store" cash NOI in the third quarter increased 14% to $11.2
million over prior year, in spite of increased utility costs associated with
this year's hot summer. Operating cash margins improved from 49% to 52% over
the prior year on aggregate revenue growth of $1.5 million or 7%. This
improvement resulted in part from the combination of a $1.1 million increase
in rental revenue (as occupancy increased from 95% to 96%) offset by a 3%
increase in operating costs of $0.3 million. Cost increases resulted from
higher utilities costs throughout the portfolio ($0.2 million) and increased
occupancy associated with the re-development of 17 Battery Place ($0.1
million).

         The Company's EBITDA margins before ground rent improved to 58%
compared to 54% in the third quarter of 1998. EBITDA margins after ground rent
were 52% compared to 45% in the third quarter of 1998. This increase was
driven by increased property GAAP NOI ($8.9 million) and an increase in
investment and other income of $1.3 million. Increases were partially offset
by increased MG&A.

The $3.3 million increase in FFO over the third quarter came from:
     $2.5 million from lease-up of approximately 330,000 square feet of vacant
     space and a positive spread in replacement rents of 26%;
     $4.8 million came from the normalization of GAAP NOI from 1998 and 1999
     acquisitions:
     $1.0 million from increased escalation and signage revenues.
     $1.7 million was derived from investment and other income, the Company's
     joint venture and taxable subsidiaries income;

Offsetting these improvements was an increase of $6.7 million from interest
costs and MG&A.

SL Green's total combined debt at the quarter's close was $422.4 million,
translating to a current debt to market cap ratio of 39% at quarter end.

NEW INVESTMENTS TO DATE

    The Company announced today that it has exercised its rights to acquire
    the remaining 35% interest in the BMW Building located at 555 West 57th
    Street, New York, New York for $34.1 million. This acquisition is expected
    to be completed for cash in the amount of $18.7 million. The acquisition
    price is consistent with the price paid by the Company for the 65%
    controlling interest acquired in January, 1999. The Company's total
    acquisition cost basis in the property is approximately $100 million, or
    $106 per square foot.

    Simultaneous with the closing of this transaction, the Company has
    obtained a new $70 million first mortgage commitment from The Bank of New
    York. The new first mortgage has a term of 5 years and a variable interest
    rate. The Company intends to eliminate the variable rate exposure through
    an interest rate swap. The proceeds of the refinancing will be used to
    repay the existing first mortgage loan of $44 million, as well as provide
    funds for the acquisition of the various equity interests and capital
    needs at the property.

     The property is fully occupied with average in place rents approximately
     30% below current market rents of $30 per square foot. Reflecting the
     strength of the New York leasing market, the Company has already
     recaptured and re-leased over 10% of the property space, realizing
     immediate benefits of the market. Key tenants in the building include
     BMW, City University of New York (John Jay College), St. Luke's Roosevelt
     Hospital, CBS and Greater New York Hospital.

     On August 3, 1999, the Company announced a joint venture agreement
     with Morgan Stanley Real Estate Fund III, LP whereby the Company retained
     a 35% interest in 90 Broad Street, New York. The 339,000 square foot
     office building was purchased by SL Green in May 1999 as a part of the
     multi-property purchase from Tower Realty. SL Green was appointed the
     operating partner of the venture and managing agent for the property and
     will be compensated on a fee basis.

     On August 31, 1999, the Company announced a joint venture agreement
     with Carlyle Realty to co-invest in the $93 million acquisition of 1250
     Broadway, a 670,000 square foot office building in Manhattan. The terms
     of the agreement provide SL Green with a 49.9% interest in the joint
     venture. The purchase and subsequent capital improvement program will be
     funded partially with a $69.65 million first mortgage. SL Green will
     manage the venture and will provide management, leasing and construction
     services on a fee basis at the property.

At September 30, 1999, SL Green's portfolio consisted of 24 properties, 21 of
which are wholly owned, comprising approximately 8.5 million rentable square
feet. This portfolio has grown by 2.3 million square feet (37%) since
September 30, 1998.

SL Green Realty is a self-administered and self-managed real estate investment
trust ("REIT") that acquires, owns and manages a Class B Manhattan office
portfolio. The Company is the only publicly held REIT which exclusively
specializes in this niche.
