                                   (UNAUDITED)

      The unaudited pro forma consolidated balance sheet of SL Green Realty
Corp. (the "Company") as of March 31, 2001 has been prepared as if the Company's
acquisition of the fee interest in 317 Madison Avenue ("317 Madison") had been
consummated on March 31, 2001. The unaudited pro forma consolidated income
statements for the year ended December 31, 2000 and the three months ended March
31, 2001 are presented as if the Company's acquisition of 317 Madison occurred
on January 1, 2000 and the effect was carried forward through the year and the
three month period.

      On June 7, 2001, the Company announced that it had acquired the 450,000
square foot, 22-story office building at 317 Madison, New York, New York. The
property 317 Madison is located at the Northeast corner of Madison Avenue and
42nd Street in the Grand Central sub-market of midtown Manhattan.

      The pro forma consolidated financial statements do not purport to
represent what the Company's financial position or results of operations would
have been assuming the completion of the Company's acquisition of 317 Madison
had occurred on January 1, 2000 and period indicated, nor do they purport to
project the Company's financial position or results of operations at any future
date or for any future period. These pro forma consolidated financial statements
should be read in conjunction with the Company's 2000 Annual Report on Form 10-K
and the Company's Quarterly Report on Form 10-Q for the quarterly period ended
March 31, 2001.

includes assessing the accounting principles used and the significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our

                               317 Madison Avenue
              Notes to Statements of Revenues and Certain Expenses
                             (Dollars in thousands)
                      For the year ended December 31, 2000


1.   BASIS OF PRESENTATION

Presented herein is the statement of revenues and certain expenses related to
the operations of the property, located at 317 Madison Avenue, located in the
Grand Central South sub-market, in the borough of Manhattan in New York City,
(the "Property"). On June 7, 2001, SL Green Realty Corp. (the "Company")
acquired the Property, for an aggregate purchase price of approximately
$105,600.

The accompanying statement of revenues and certain expenses has been prepared in
accordance with the applicable rules and regulations of the Securities and
Exchange Commission for the acquisition of real estate properties. Accordingly,
the statement of revenues and certain expenses excludes certain revenues and
expenses that may not be comparable to those expected to be incurred by the
Company in the proposed future operations of the Property. Items excluded
consist of amortization and depreciation, interest expense, interest income on
the general partner's level, professional fees that relate to the Partnership
that owned the Property and the interest rate swap related to the loan.

2.   USE OF ESTIMATES

The preparation of statement of revenues and certain expenses in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that effect the amounts reported in
the statement of revenues and certain expenses and accompanying notes. Actual
results could differ from those estimates.

3.   REVENUE RECOGNITION

The Property is leased to tenants under operating leases. Minimum rental
income is generally recognized on a straight-line basis over the term of the
lease. The excess of amounts due pursuant to the underlying leases over
amounts recognized for the year ended December 31, 2000 and the three months
ended March 31, 2001, amounted to approximately $125 and $5 (unaudited),
respectively.

4.   CONCENTRATION OF REVENUE

There are no tenants that comprise more than 10% of the Property's rental
revenue for the year ended December 31, 2000 and for the three months ended
March 31, 2001, respectively.

5.   MANAGEMENT AGREEMENTS AND RELATED PARTY TRANSACTIONS

Until June 6, 2001, Williamson, Picket, Gross, Inc. managed the Property. The
management fees were based on 1.5% of gross rents collected, as defined in
the agreement. The fee incurred for managing the Property for the year ended
December 31, 2000 and the three months ended March 31, 2001 was approximately
$189 and $48 (unaudited), respectively.

                             (Dollars in thousands)

5.   MANAGEMENT AGREEMENTS AND RELATED PARTY TRANSACTIONS (CONTINUED)

Pursuant to a separate agreement, the general partner performs supervisory and
administrative services for an annual compensation of 3% of rent income, as
defined in the agreement. The fee incurred for the year ended December 31, 2000
and the three months ended March 31, 2001 was approximately $384 and $97
(unaudited), respectively, and is included in management fees on the statement
of revenues and certain expenses.

An affiliate of the prior owner occupies an office in the Property, free of
rent.

6.   LEASE AGREEMENTS

The Property is being leased to tenants under operating leases with term
expiration dates ranging from 2001 to 2010. The minimum rental amounts due under
the leases are generally subject to scheduled fixed increases. The leases
generally also require that the tenants reimburse the Property for increases in
certain operating costs and real estate taxes above their base year costs.
Approximate future minimum rents to be received over the next five years and
thereafter for non-cancelable operating leases as of December 31, 2000
(exclusive of renewal option periods) are as follows:


                                       
                  2001                    $ 11,379
                  2002                      10,698
                  2003                      10,045
                  2004                       8,300
                  2005                       6,404
                  Thereafter                10,690
                                          --------
                                          $ 57,516


7.    BENEFIT PLANS

The building employees are covered by multi-employer defined benefit pension
funds and post-retirement health and welfare plans. Contributions to these plans
amounted to $74 and $21 (unaudited) during the year ended December 31, 2000 and
the three months ended March 31, 2001, respectively. Separate actuarial
information regarding such plans, is not made available to the contributing
employers by the union administrators or trustees, since the plans do not
maintain separate records for each reporting unit.

8.    INTERIM UNAUDITED FINANCIAL INFORMATION

The financial statement for the three months ended March 31, 2001 is unaudited,
however, in the opinion of management all adjustments (consisting solely of
normal recurring adjustments), necessary for a fair presentation of the
financial statement for the interim period have been included. The results of
the interim period are not necessarily indicative of the results to be obtained
for a full fiscal year.
