FINANCIAL RESULTS
-----------------

NEW YORK, NY, OCTOBER 23, 2001 - SL Green Realty Corp. (NYSE:SLG) reported
improved operating results for the three months ended September 30, 2001. During
the period, funds from operations (FFO) before minority interests totaled $24.0
million, or $0.73 per share (diluted), compared to $20.1 million, or $0.70 per
share (diluted), for the same quarter in 2000. The 2001 quarterly results
include a $1.0 million charge, or $0.03 per share, for a one-time contribution
to the Twin Towers Fund. Excluding this contribution, third quarter earnings
would have been $0.76 per share, representing a 9% improvement over the prior
year. The FFO per share calculation is reflective of the Company's five million
common share issuance in the third quarter of 2001 which increased the weighted
average dilutive shares outstanding to 36.1

                                                                               1


million, a 13% increase over the prior year. This growth was primarily
attributable to strong same store cash NOI growth of 15%.

Nine month results were also strong, reflecting a 14% FFO increase over 2000 as
FFO before minority interests totaled $68.6 million or $2.25 per share
(diluted), compared to $55.6 million or $1.97 per share (diluted) for the same
period in the previous year. This growth is also attributable to strong same
store cash NOI growth of 16%.

For the quarter, net income available to common shareholders, adjusted for
property sales, extraordinary items and the cumulative effect of an accounting
change increased 14% to $13.6 million, or $0.43 per share (diluted) as compared
to $11.9 million, or $0.43 per share (diluted), for the same period in the
previous year. For the nine months ended September 30, 2001, adjusted net income
increased 25% to $39.1 million, or $1.36 per share (diluted), as compared to
$31.4 million, or $1.16 per share (diluted), for the same period in the previous
year.

Total quarterly revenues increased in the third quarter to $61.9 million (1.7%)
compared to last year's $60.9 million. The $1.0 million growth in revenue
resulted primarily from:

     o     2001 acquisitions ($6.0 million)
     o     2001 same store portfolio ($1.7 million).

These revenue increases were partially offset by reduced revenues of properties
sold ($6.0 million) and investment and preferred equity income ($1.0 million).
The $1.0 million decrease in investment and preferred equity income is due to
the following: (i) $0.7 million from yield maintenance received from the early
redemption of a preferred equity investment on 1370 Avenue of the Americas in
third quarter 2000 and (ii) lower yields primarily from reduced interest rates
($0.5 million) and investment spreads ($0.9 million) and the decrease is
partially offset by the higher weighted average structured finance investment
balance outstanding ($1.3 million).

During the third quarter, same store cash NOI increased $3.3 million to $25.6
million, as compared to $22.3 million over the same period in the prior year.
Cash NOI margins before ground rent improved year over year from 55.2% to 60.2%.
The improvement in cash NOI was driven primarily by a $3.4 million increase in
cash revenue due to:

     o     A 45% increase in replacement rents over previous fully-escalated
           rents ($1.3 million)
     o     Reduced free and straight-line rents ($1.7 million)
     o     Rent steps from current in-place tenants ($0.5 million)
     o     $0.9 million increase in escalation and reimbursement income
           primarily from increased electric reimbursement, operating expense
           reimbursements and percentage rent escalations
     o     Decrease in revenue due to lower occupancy primarily due to planned
           vacancy at 1466 Broadway ($0.4 million)
     o     Decrease in revenue due to higher reserves for tenant allowance ($0.6
           million).

                                                                               2


The net increase in revenue was partially offset by $0.2 million increase in
real estate taxes with operating expenses remaining flat. Approximately 90.0% of
the quarterly electric expense was recovered through the utility clause in the
tenants' leases.

The Company's third quarter EBITDA increased $1.6 million resulting in increased
margins before ground rent of 66.0% in 2001 as compared to 65.4% for the same
period last year. After ground rent, margins improved to 60.6% in 2001 from
59.7% in the corresponding prior year period. Margin improvement was driven by
the Company's primary real estate investment themes:

     o     GAAP NOI of $4.4 million

             o   $3.4 million increase from 2001 acquisitions
             o   $1.8 million increase from same store (7% improvement)
             o   $2.2 million increase from net income from unconsolidated joint
                 ventures
             o   $3.3 million decrease from properties sold or contributed to
                 joint ventures.

These increases in EBITDA were partially offset by (i) an increase in MG&A ($1.6
million) primarily due to a $1.0 million contribution to the Twin Towers fund
and increased personnel costs, (ii) a decrease in investments and other income
($0.7 million) and (iii) a loss from equity in affiliates as compared to net
income in the prior year ($0.1 million).

FFO for the quarter ended September 30, 2001 improved $3.9 million primarily as
a result of a $1.6 million increase in EBITDA, increased FFO adjustment from
joint ventures ($1.4 million) and lower interest costs ($0.9 million). Lower
interest costs ($0.9 million) were associated with: higher average debt levels
due to net acquisition and new investment debt activity ($1.5 million), the
higher average debt levels due to the funding of ongoing capital projects and
working capital requirements ($0.2 million), and the proceeds from the Company's
July common stock offering ($1.6 million) offset by lower interest rates from
floating rate debt ($0.9 million).

During the quarter ended September 30, 2001, the Company recorded an
extraordinary loss of $0.3 million due to the early extinguishment of debt that
was excluded from the Company's FFO results. The 2001 quarterly results of the
Company exclude a gain on sale of property interest that totaled $0.6 million
and the 2000 quarterly results exclude a gain on redemption of a preferred
equity investment totaling ($5.6 million).

At the end of the quarter, consolidated debt totaled $484.1 million, reflecting
a debt to market capitalization ratio of 30.0%.

                              ---------------------

On September 24, 2001, the Company acquired a 49.9% interest in 1250 Broadway

approximately 685,000 square feet, and occupies the block

                                                                               3
