    Distributions on the    % Preferred Income Equity Redeemable Shares(SM), a
series of preferred stock, $.01 par value per share (the "PIERS"), offered
hereby (the "PIERS Offering"), of SL Green Realty Corp. (the "Company"), a
Maryland corporation which qualifies for federal income tax purposes as a real
estate investment trust (a "REIT"), are cumulative from the date of issue and
are payable quarterly on or about the fifteenth day of January, April, July and
October of each year, commencing on July 15, 1998 (each a "Distribution Payment
Date"), in an amount per share equal to the greater of (i)    % of the
liquidation preference per annum (equivalent to $         per annum per PIERS)
or (ii) the cash dividends paid or payable (determined on each of the
Distribution Payment Dates referred to above) on a number of shares of common
stock, $.01 par value per shares of the Company ("Common Stock") equal to the
number of shares of Common Stock (or portion thereof) into which a PIERS is
convertible. See "Capital Stock -- PIERS -- Distributions."
    
 
    The PIERS are convertible at any time, at the option of the holder, unless
previously redeemed, into Common Stock at a conversion price of $     per share
of Common Stock (equivalent to a conversion rate of    shares of Common Stock
for each PIERS) (the "Conversion Price"), subject to adjustment in certain
circumstances described herein. Except in certain circumstances relating to the
preservation of the Company's status as a REIT for federal income tax purposes,
the PIERS are not redeemable prior to July 15, 2003. On and after July 15, 2003,
the PIERS will be redeemable by the Company, in whole or in part, at the option
of the Company, for such number of shares of Common Stock as are issuable at the
Conversion Price, provided that the Company may exercise this option only if for
20 trading days within any 30 consecutive trading days, including the last day
of such period, the closing price of the Common Stock on the New York Stock
Exchange ("NYSE") exceeds $     per share, subject to adjustment in certain
circumstances. On and after July 15, 2003, the PIERS may also be redeemed at the
option of the Company, in whole or in part, initially at $       per PIERS and
thereafter at prices declining to $25.00 per share on and after July 15, 2007,
plus in each case accumulated and unpaid distributions, if any, to the
redemption date, provided that the Company may exercise this option only if the
redemption price (other than the portion thereof consisting of accumulated and
unpaid distributions) is paid solely out of the sale proceeds of other shares of
stock of the Company, which may include other series of preferred stock, and
from no other source. The PIERS are subject to mandatory redemption on April 15,
2008 at a price of $25 per PIERS, plus accumulated and unpaid distributions to
the redemption date.
 
   
    Application will be made to list the PIERS and the Common Stock issuable
upon conversion or redemption of the PIERS on the NYSE. The PIERS will be listed
under the Symbol "SLGPrA," and the Common Stock will be listed under the symbol
"SLG." Trading of the PIERS is expected to commence on the NYSE within 30 days
from the closing of the PIERS Offering. On April 23, 1998, the last reported
sale price of the Common Stock on the NYSE was $23.875 per share. See "Capital
Stock -- Restrictions on Transfer."
    
                           --------------------------
 
    Concurrent with this offering of PIERS by the Company (the "PIERS Offering")

    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION INCLUDED ELSEWHERE IN THIS PROSPECTUS. UNLESS OTHERWISE INDICATED,
THE INFORMATION CONTAINED IN THIS PROSPECTUS ASSUMES THAT (I) THE OFFERING PRICE
PER SHARE FOR COMMON STOCK OFFERED BY THE COMMON OFFERING IS $23.875 AND (II)
THE UNDERWRITERS' OVER-ALLOTMENT OPTION IS NOT EXERCISED. AS USED HEREIN, (I)
THE "COMPANY" MEANS SL GREEN REALTY CORP., A MARYLAND CORPORATION, AND ONE OR
MORE OF ITS SUBSIDIARIES (INCLUDING SL GREEN OPERATING PARTNERSHIP, L.P.), AND
THE PREDECESSORS THEREOF OR, AS THE CONTEXT MAY REQUIRE, SL GREEN REALTY CORP.
ONLY OR SL GREEN OPERATING PARTNERSHIP, L.P. ONLY AND (II) "SL GREEN" MEANS SL
GREEN PROPERTIES, INC., A NEW YORK CORPORATION, AS WELL AS THE AFFILIATED
PARTNERSHIPS AND OTHER ENTITIES THROUGH WHICH STEPHEN L. GREEN HAS HISTORICALLY
CONDUCTED COMMERCIAL REAL ESTATE ACTIVITIES. SEE "GLOSSARY OF SELECTED TERMS"
FOR THE DEFINITIONS OF CERTAIN TERMS USED IN THIS PROSPECTUS.
 
                                  THE COMPANY
 
    SL Green Realty Corp. (together with its subsidiaries, the "Company") is the
first fully integrated, self-administered and self-managed equity real estate
investment trust ("REIT") solely engaged in owning, managing, leasing, acquiring
and repositioning Class B office properties in Manhattan. The Company continues
to be the only Class B office REIT in New York City. The Company currently owns
interests in 15 Class B office properties (the "Properties") containing
approximately 5.0 million rentable square feet located in Manhattan. As of
December 31, 1997, the Properties were 90% leased. In addition, the Company acts
as leasing agent and/or manages 27 properties (including the Properties owned by
the Company) encompassing approximately 8.2 million rentable square feet.
 
    The term "Class B" is generally used in the Manhattan office market to
describe office properties which are more than 25 years old but which are in
good physical condition, enjoy widespread acceptance by high-quality tenants and
are situated in desirable locations in Manhattan. Class B office properties can
be distinguished from Class A properties in that Class A properties are
generally newer properties with higher finishes and obtain the highest rental
rates within their markets.
 
    A variety of tenants who do not require, desire or cannot afford Class A
space are attracted to Class B office properties due to their prime locations,
excellent amenities, distinguished architecture and relatively less expensive
rental rates. Class B office space has historically attracted many smaller
growth oriented firms (many of which have fueled the recent growth in the New
York metropolitan economy) and has played a critical role in satisfying the
space requirements of particular industry groups in Manhattan, such as the
advertising, apparel, business services, engineering, not-for-profit, "new
media" and publishing industries. In addition, several areas of Manhattan,
including many in which particular trades or industries traditionally
congregate, are dominated by Class B office space and contain no or very limited
Class A office space. Examples of such areas include the Garment District (where
three of the Properties are located), the Flatiron District (where one Property
is located), the areas immediately south and north of Houston Street ("Soho" and
"Noho", respectively), Chelsea (where one Property is located), and the area
surrounding the United Nations (where one Property is located). Businesses
significantly concentrated in certain of these areas include those in the
following industries: new media, garment, apparel, toy, jewelry, interior
decoration, antiques, giftware, contract furnishing and UN-related businesses.
The concentration of businesses creates strong demand for the available Class B
office space in those locations.
 
    A description of the structure of the Company is set forth below under
"Structure and Formation of the Company."
 
    The Company believes that current developments in the New York metropolitan
economy provide an attractive environment for owning, operating and acquiring
Class B office properties in Manhattan. The combined vacancy rate for Class A
and Class B office space in the Midtown Markets (as defined herein) declined to
9.1% at March 31, 1998 from a 1990s high of 16.8% at year-end 1991. The Class B
segment of this market tightened to a vacancy rate of 9.8% at March 31, 1998
from its 1990s high of 17.2% at year-end
 
                                       1
<PAGE>
1992, a 43.0% decline. Rosen Consulting Group, a national real estate consulting
group, projects vacancy rates in the Class B Midtown Markets to further drop to
7.0% by 2002, resulting in projected average asking market rents of $34.14 per
square foot, a 23.1% increase over average asking rents as of December 31, 1997
of $27.74 per square foot. See "Business and Growth Strategies--The Market
Opportunity" and "Risk Factors--The Company's Dependence on the Midtown Markets
Due to Limited Geographic Diversification Could Adversely Affect The Company's
Financial Performance" below. The Company seeks to capitalize on growth
opportunities in its marketplace by acquiring Class B office properties on a
selective basis and, when necessary, enhancing their value after acquisition
through repositioning of the properties in their respective submarkets. See
"Business and Growth Strategies--Growth Strategies."
 
    The Company operates from its Manhattan headquarters and is a fully
integrated real estate company with approximately 331 employees and in-house
expertise in acquisitions, finance, asset management, leasing and construction.
The Company's founder, Stephen L. Green, along with the other six senior
officers of the Company, have an average of more than 20 years of experience in
the real estate industry. See "Management--Directors and Executive Officers."
Upon completion of the Offerings, approximately 9.6% of the equity of the
Company, on a fully diluted basis, will be beneficially owned by officers and
directors of the Company.
 
HIGHLIGHTS OF RECENT DEVELOPMENTS
 
    Since its initial public offering in August 1997 (the "IPO"), the Company
has acquired interests in six of the Properties (collectively, the "Acquired
Properties"), containing approximately 2.8 million rentable square feet. The
Acquired Properties include, among others, 110 East 42nd Street (formerly known
as the Bowery Savings Bank Building), and the Graybar Building at 420 Lexington
Avenue. The Acquired Properties were purchased for an aggregate purchase price
of approximately $259 million. As of April 24, 1998, the Company had entered
into agreements to purchase four additional office properties (the "Pending
Acquisitions") containing an aggregate of approximately 1,055,000 rentable
square feet for an aggregate purchase price of $111.0 million.
 
                                  RISK FACTORS
 
    An investment in the Common Stock involves various risks, and prospective
investors should carefully consider the matters discussed under "Risk Factors"
prior to making an investment in the Company. Such risks include, among others:
 
    - concentration of the Properties in Manhattan (primarily in the Midtown
      Markets), and the dependence of the Properties on the conditions of the
      New York metropolitan economy and the Midtown Markets (as defined herein),
      which increases the risk of the Company's being adversely affected by a
      downturn in the New York metropolitan economy or the Midtown Markets;
 
    - the possibility that one or more of the Pending Acquisitions will not
      close and that the Company may be unable to apply proceeds from the
      Offerings toward other suitable acquisitions;
 
    - integration of recent or expected acquisitions, including the risk that
      certain of these properties may have characteristics or deficiencies
      unknown to the Company that affect their valuation or revenue potential;
 
   
    - an affiliate of Lehman Brothers, the lead managing underwriter of the
      Offerings, will receive $240 million of the net proceeds of the Offerings
      in repayment of a loan made to the Company to acquire properties, in
      addition to underwriting discounts and commissions;
    
 
    - conflicts of interest involving officers and directors of the Company in
      business decisions regarding the Company, including conflicts associated
      with sales and refinancings of the Properties and the prepayment of debt
      secured by the Properties and conflicts associated with the provision of
      cleaning and security services with respect to the Properties by entities
      controlled by related parties;
 
                                       2
<PAGE>
    - limitations on the ability of the Company to sell, or reduce the amount of
      mortgage indebtedness on, two of the Properties (673 First Avenue and 470
      Park Avenue South) for up to 12 years following the completion of the IPO
      (the "Lock-out Period"), except in certain circumstances (the "Lock-out
      Provisions"), which limitations could benefit certain participants in the
      Formation Transactions (as defined herein) (including Stephen L. Green,
      members of his immediate family and unaffiliated partners in the
      Property-owning entities), even if any such sale or reduction in mortgage
      indebtedness would be in the best interests of the Company's stockholders,
      and the possibility that future property acquisitions in which the Company
      uses partnership interests as consideration will include comparable
      limitations;
 
    - the anti-takeover effect of limiting actual or constructive ownership of
      Common Stock to 9.0% of the number of outstanding shares, subject to
      certain exceptions, and of certain other provisions contained in the
      organizational documents of the Company and the Operating Partnership,
      which could have the effect of delaying, deferring or preventing a
      transaction or change in control of the Company that might involve a
      premium price for the Common Stock or otherwise would be in the best
      interests of the Company's stockholders;
 
    - dependence on smaller and growth-oriented businesses to rent Class B
      office space;
 
    - office real estate investment risks, such as the effect of the large
      number of competitive office properties in the Midtown Markets, the need
      to renew leases or re-lease space upon lease expirations and to pay
      renovation and re-leasing costs in connection therewith, the effect of
      economic and other conditions on office property cash flows and values,
      the ability of tenants to make lease payments, the ability of a property
      to generate revenue sufficient to meet operating expenses (including
      future debt service), potential environmental liabilities, the illiquidity
      of real estate investments and the possibility that acquired properties
      fail to perform as expected;
 
    - the possibility that the Board of Directors of the Company may in the
      future amend or revise the investment, financing, borrowing, distribution
      and conflicts of interest policies of the Company without a vote of the
      Company's stockholders;
 
    - the absence of limitations in the Company's organizational documents on
      the incurrence of debt;
 
    - taxation of the Company as a corporation if it fails to qualify as a REIT
      for Federal income tax purposes, the Company's liability for certain
      Federal, state and local income taxes in such event and the resulting
      decrease in cash available for distribution; and
 
    - possible environmental liability in connection with the Company's
      ownership and/or operation of the Properties.

PENDING ACQUISITIONS
 
    As of April 24, 1998, the Company had executed contracts to acquire four
additional office properties containing approximately 1,055,000 rentable square
feet for an aggregate purchase price of approximately $111.0 million. The
Company intends to use a portion of the net proceeds from the Offerings to
complete the Pending Acquisitions within 60 days after the closing of the
Offerings; however, purchase of the Pending Acquisitions is subject to the
Company's completion of due diligence and the satisfaction of other customary
conditions to closing, and there can be no assurance that any of the Pending
Acquisitions will be completed. See "Risk Factors--Risk that Pending
Acquisitions Will Not Close." In addition to the Pending Acquisitions, as part
of its ongoing business, the Company continually engages in discussions with
various property owners regarding possible portfolio or single asset
acquisitions. No assurance can be made that the Company will acquire any of the
property opportunities currently under review. The following table sets forth
certain data regarding the Pending Acquisitions:

(1) As of March 31, 1998, this Property was 96% leased.
 
(2) The decrease in percent leased is due to a tenant leaving prior to the lease
    expiration date. The space was leased to a new tenant in January 1998,
    increasing the percent leased to 91% and increasing the weighted average
    percent leased rate of these three properties to 93%.
 
CREDIT FACILITIES
 
    On December 19, 1997 the Company entered into a $140 million three year
senior unsecured revolving credit facility (the "Credit Facility") due December
2000. Availability under the Credit Facility may be limited to an amount less
than $140 million. Availability is calculated by reference to several factors
including recent acquisition activity and most recent quarterly property
performance. Outstanding loans under the Credit Facility bear interest at a rate
per annum equal to the London Interbank Offered Rate ("LIBOR") applicable to
each interest period plus 130 basis points to 145 basis points per annum. The
Credit Facility requires the Company to comply with certain covenants, including
but not limited to, maintenance of certain financial ratios. At December 31,
1997 the outstanding amount of indebtedness under the Credit Facility was $76
million, and the interest rate on such indebtedness was 7.265% per annum.
 
    On December 30, 1997 the Company entered into a $7 million additional
advance under its existing mortgage loan which is secured by 50 West 23rd
Street. The note bore interest at a rate of LIBOR plus 175 basis points (7.6875%
at December 31, 1997). On April 3, 1998, the interest rate on this note was
fixed at 7.06%, and will mature co-terminous with the underlying mortgage note.
As of April 15, 1998, the current amount of the mortgage note was $21 million.
 
    On March 18, 1998, the Company asked the Credit Facility banking group to
temporarily relieve the Company from its obligations under the financial
covenants of the Credit Facility, in order to close an additional financing
provided by Lehman Brothers necessary to acquire the Helmsley Properties (the
"Acquisition Facility"). The Acquisition Facility, with a borrowing capacity of
up to $275 million, financed the purchase of the Helmsley Properties, paid off
the outstanding balance on the Credit Facility and provided ongoing liquidity
for future acquisition and corporate needs. The term of this facility is one
year. The interest rate is determined by a schedule of the principal balance of
the loan outstanding and the applicable quarterly period extending from March
18, 1998 through the maturity date. The outstanding principal amount of $240
million under the Acquisition Facility will be paid from the proceeds of the
Offerings. The Credit Facility will remain committed but unused until the
Acquisition Facility is repaid, at which time the Company will be in compliance
with all financial covenants under the Credit Facility and will again be able to
draw additional funds under such Credit Facility.

                         BUSINESS AND GROWTH STRATEGIES
 
    The Company's primary business objective is to maximize total return to
stockholders through growth in distributable cash flow and appreciation in the
value of its assets. The Company seeks to achieve this objective by capitalizing
on the external and internal growth opportunities described below.
 
    Unless indicated otherwise, information contained herein concerning the New
York metropolitan economy and the Manhattan office market is derived from a
report commissioned by the Company and prepared by the Rosen Consulting Group,
and is included herein (the "Rosen Market Study"), with the consent of the Rosen
Consulting Group.
 
THE MARKET OPPORTUNITY
 
    - The Company believes that the continuing recovery of the New York
      commercial real estate market from the downturn of the late 1980s and
      early 1990s creates an attractive environment for owning, operating and
      acquiring Class B office properties in Manhattan.
 
    - Continued net private sector job growth (especially in smaller companies),
      an improving business environment and "quality of life" enhancements in
      New York City have led to growing demand for office space in Manhattan.
 
    - The Midtown Markets in particular have benefited from the growth in
      smaller companies that have traditionally been attracted to Class B space
      in the Midtown Markets due to its prime locations and relatively less
      expensive rental rates (as compared to Class A space) and from the
      relocation of larger firms from Class A space to Class B space.
 
    - The Company expects the supply of office space in the Midtown Markets to
      remain relatively stable through the year 2000 because new construction
      generally is not economically feasible at current market rental rates and
      property values, there are relatively few sites available for construction
      and the lead time required for construction typically exceeds three years.
 
    - As a result of these positive supply and demand fundamentals, the Class B
      office vacancy rate in the Midtown Markets declined to 9.8% from its 1990s
      high of 17.2% in 1992 and asking rental rates for Class B office space in
      the Midtown Markets increased to $27.74 per square foot as of March 31,
      1998 from their 1990s low of $21.90 per square foot as of year-end 1993.
      These developments coupled with projected continuing decreases in vacancy
      rates and increases in rental rates create attractive opportunities for
      owning and acquiring Class B office properties in Manhattan. However,
      concentration of most of the Properties in these markets increases the
      risk of the Company being adversely affected by any downturn in the New
      York metropolitan economy. See "Risk Factors--The Company's Dependence on
      the Midtown Markets Due to Limited Geographic Diversification Could
      Adversely Affect the Company's Financial Performance."
 
                                       6
<PAGE>
GROWTH STRATEGIES
 
    - The Company seeks to capitalize on current opportunities in the Class B
      Manhattan office market through (i) property acquisitions--continuing to
      acquire Class B office properties at significant discounts to replacement
      costs that provide attractive initial yields and the potential for cash
      flow growth, (ii) releasing expiring leases to increasing market rents,
      (iii) property repositioning-- repositioning acquired properties that are
      underperforming through renovations, active management and proactive
      leasing and (iv) integrated leasing and property management.
 
    - PROPERTY ACQUISITIONS. In acquiring properties, the Company believes that
      it will have the following advantages over its competitors: (i) over 18
      years experience as a full service, fully integrated real estate company
      focused on the Class B office market in Manhattan, (ii) enhanced access to
      capital as a public company, (as compared to the generally fragmented and
      far less institutional ownership of competing Manhattan Class B office
      properties) and (iii) the ability to offer tax-advantaged structures to
      sellers.
 
    - RE-LEASING EXPIRING LEASES TO INCREASING MARKET RENTS. Although there can
      be no assurances in this regard, the Company believes that as the
      commercial real estate market in Manhattan continues to improve, there
      will be increasing demand for office space and declining vacancies which
      are expected to continue to result in increasing market rents. The Company
      believes it has significant opportunities to increase cash flow during
      such periods of increasing market rents by renewing or re-leasing expiring
      leases at increased market rents.
 
    - PROPERTY REPOSITIONING. The Company believes that there are a significant
      number of potential acquisitions that could greatly benefit from
      management's experience in enhancing property cash flow and value by
      renovating and repositioning properties to be among the best in their
      submarkets.
 
    - INTEGRATED LEASING AND PROPERTY MANAGEMENT. The Company seeks to
      capitalize on management's extensive knowledge of the Class B Manhattan
      marketplace and the needs of the tenants therein through its proactive
      approach to leasing and management, which includes (i) the use of in-depth
      market research, (ii) the utilization of an extensive network of
      third-party brokers, (iii) comprehensive building management analysis and
      planning and (iv) a commitment to tenant satisfaction and providing "Class
      A" tenant services. The Company believes that its proactive leasing
      efforts have contributed to average occupancy rates at the Properties that
      are above the market average. See "Business and Growth Strategies--Growth
      Strategies--Integrated Leasing and Property Management." In addition, the
      Company's commitment to tenant service and satisfaction is evidenced by
      the renewal of approximately 75% of the expiring rentable square footage
      75% of the expiring leases determined by number of leases) at the
      Properties owned and managed by the Company and its predecessors during
      the period from January 1, 1994 through December 31, 1997.

                                 THE PROPERTIES
 
THE PORTFOLIO
 
    GENERAL.  The Company owns or has contracted to acquire interests in 19
Class B office properties located primarily in Manhattan which contain
approximately 6.1 million rentable square feet (one property is located in
downtown Manhattan and one property is located in Brooklyn). Of these 19
properties, nine properties containing approximately 2.2 million rentable square
feet were owned or acquired by the Company at the time of the IPO (the "Initial
Properties"), six properties containing approximately 2.8 million rentable
square feet have been acquired by the Company since the IPO (the "Acquired
Properties") and three properties containing approximately 1,055,000 rentable
square feet are currently under contract by the Company (the "Pending
Acquisitions"). Certain of the Properties include at least a small amount of
retail space on the lower floors, as well as basement/storage space. One
Property (673 First Avenue) and one Pending Acquisition (711 Third Avenue)
include underground parking.
 
    The following table sets forth certain information with respect to each of
the Properties and the Pending Acquisitions as of December 31, 1997:

- ------------------------
 
   
 (1) As used throughout this Prospectus, Annualized Rent represents the monthly
     contractual rent under existing leases as of December 31, 1997 multiplied
     by 12. This amount reflects total rent before any rent abatements and
     includes expense reimbursements, which may be estimated as of such date.
     Total rent abatements for leases in effect as of December 31, 1997 for the
     12 months ending December 31, 1998 are approximately $888,000.
    
 
 (2) Annualized Rent Per Leased Square Foot, as used throughout this Prospectus,
     represents Annualized Rent, as described in footnote (1) above, presented
     on a per leased square foot basis.
 
 (3) As used throughout this Prospectus, Annual Net Effective Rent Per Leased
     Square Foot represents (a) for leases in effect at the time an interest in
     the relevant property was first acquired by the Company or its
     predecessors, the remaining lease payments under the lease including
     escalations (excluding operating expense pass-throughs, if any) divided by
     the number of months remaining under the lease multiplied by 12 and (b) for
     leases entered into after an interest in the relevant property was first
     acquired by the Company or its predecessors and for leases at the Acquired
     Properties, all lease payments under the lease including escalations
     (excluding operating expense pass-throughs, if any) divided by the number
     of months in the lease multiplied by 12, and, in the case of both (a) and
     (b), minus tenant improvement costs and leasing commissions, if any, paid
     or payable by the Company or its predecessors and presented on a per leased
     square foot basis. Annual Net
 
                                       8
<PAGE>
     Effective Rent Per Leased Square Foot includes future contractual increases
     in rental payments and therefore, in certain cases, may exceed Annualized
     Rent Per Leased Square Foot.
 
 (4) The Company holds a long-term leasehold interest in the land and
     improvements with respect to this Property. See "The Properties--673 First
     Avenue," "--36 West 44th Street (The Bar Building)" and "--1140 Avenue of
     the Americas."
 
 (5) 470 Park Avenue South is comprised of two buildings, 468 Park Avenue South
     (a 17-story office building) and 470 Park Avenue South (a 12-story office
     building).
 
 (6) The Bar Building is comprised of two buildings, 36 West 44th Street (a
     14-story building) and 35 West 43rd Street (a four-story building).
 
 (7) The Company has a co-tenancy interest in this Property. See "The
     Properties--17 Battery Place."
 
 (8) The Company holds fee interests in condominium units comprising
     approximately 41,000 square feet of this one million square foot office
     building. The units are currently leased to primarily retail tenants. See
     "The Properties--633 Third Avenue (partial interest)."
 
 (9) The Company holds an operating sublease interest in the land and
     improvements with respect to this Property. See "The Properties--420
     Lexington Avenue (The Graybar Building)."
 
(10) The Company will hold a leasehold mortgage interest, a net sub-leasehold
     interest and a co-tenancy interest in this property. See "The
     Properties--Pending Acquisitions--711 Third Avenue."
 
(11) Does not count the 45,000 square foot garage as a lease or as part of the
     property's rentable square feet. The garage is operated by a third party
     pursuant to a management contract. If the garage were counted as leased,
     the percent leased at this Pending Acquisition would have been 81%.
 
(12) Does not include rent from the 45,000 square foot garage at this property.
 
(13) Includes approximately 5,602,600 square feet of rentable office space,
     348,700 square feet of rentable retail space, 29,700 square feet of
     mezzanine space and 75,000 square feet of garage space.

Securities Offered..............  4,000,000    % Preferred Income Equity Redeemable Shares
                                  ("PIERS") (4,600,000 PIERS if the Underwriter's
                                  over-allotment option is exercised in full).
 
Ranking.........................  The PIERS will rank senior to the Common Stock with
                                  respect to the payment of distributions and amounts upon
                                  liquidation, dissolution or winding up. See "Capital Stock
                                  -- PIERS -- Ranking."
 
Distributions...................  Distributions on the PIERS are cumulative from the date of
                                  issue and are payable quarterly on or about the fifteenth
                                  day of January, April, July and October of each year (each
                                  a "Distribution Payment Date"), commencing on July 15,
                                  1998, in an amount per share equal to the greater of (i)
                                     % of the liquidation preference per annum (equivalent
                                  to $         per annum per PIERS) or (ii) the cash
                                  dividends paid or payable (determined on each of the
                                  Distribution Payment Dates referred to above) on a number
                                  of shares of Common Stock equal to the number of shares of
                                  Common Stock (or portion thereof) into which a PIERS is
                                  convertible. See "Capital Stock -- PIERS --
                                  Distributions."
 
                                  Distributions on the PIERS will accumulate whether or not
                                  the Company has sufficient earnings, whether or not there
                                  are funds legally available for the payment of such
                                  distributions and whether or not such distributions are
                                  declared.
 
                                  If the Company designates any portion of a dividend as a
                                  "capital gain dividend," a U.S. Stockholder's share of
                                  such capital gain dividend would be an amount which bears
                                  the same ratio to the total amount of distributions paid
                                  to such U.S. Stockholder for the year as the aggregate
                                  amount designated as a capital gain dividend bears to the
                                  aggregate amount of all distributions paid on all classes
                                  of shares for the year. See "Capital Stock -- PIERS --
                                  Distributions."
 
                                  For a discussion of the tax treatment of distributions to
                                  the holders of Common Stock and PIERS, see "Material

Liquidation Preference..........  The PIERS will have a liquidation preference of $25.00 per
                                  share, plus an amount equal to accumulated and unpaid
                                  distributions. See "Capital Stock --PIERS -- Liquidation

Conversion Rights...............  The PIERS are convertible at any time, at the option of
                                  the holder, unless previously redeemed, into Common Stock
                                  at an initial conversion price of $         per share of
                                  Common Stock (equivalent to a conversion rate of
                                        shares of Common Stock for each PIERS), subject to
                                  adjustment in certain circumstances (the "Conversion
                                  Price"). See "Capital Stock -- PIERS -- Conversion Rights"
                                  and "-- Conversion Price Adjustments."

                                  2008 at a price of $25.00 per PIERS, plus accumulated and
                                  unpaid distributions to the redemption date. See "Capital
                                  Stock -- PIERS -- Redemption."
 
Redemption at Option
  of the Company................  Except in certain circumstances relating to the
                                  preservation of the Company's status as a REIT for federal
                                  income tax purposes, the PIERS are not redeemable prior to
                                  July 15, 2003. On and after July 15, 2003, the PIERS will
                                  be redeemable by the Company, in whole or in part, at the
                                  option of the Company, for such number of shares of Common
                                  Stock as are issuable at the Conversion Price (the "Stock
                                  Redemption Right"). The Company may exercise its Stock
                                  Redemption Right only if for 20 trading days within any
                                  period of 30 consecutive trading days, including the last
                                  day of such period, the closing price of the Common Stock
                                  on the NYSE exceeds $         per share, subject to
                                  adjustment in certain circumstances. See "Capital Stock --
                                  PIERS -- Redemption."
 
                                  On and after July 15, 2003, the PIERS may be redeemed at
                                  the option of the Company (the "Cash Redemption Right"),
                                  in whole or in part, initially at $      per PIERS and
                                  thereafter at prices declining to $25.00 per PIERS on and
                                  after July 15, 2007, plus in each case accumulated and
                                  unpaid distributions, if any, to the redemption date. See
                                  "Capital Stock --PIERS -- Redemption."
 
                                  The Company will not exercise its Cash Redemption Right
                                  unless the redemption price (other than the portion
                                  thereof consisting of accumulated and unpaid
                                  distributions) for the exercise of the Cash Redemption
                                  Right is paid solely out of the sale proceeds of other
                                  shares of stock of the Company, which may include other
                                  series of preferred stock ("Preferred Stock"), and from no
                                  other source.
 
Voting Rights...................  If distributions on the PIERS are in arrears for six or
                                  more quarterly periods, holders of the PIERS (voting
                                  separately as a class with all other series of Preferred
                                  Stock upon which like voting rights have been conferred
                                  and are exercisable) will be entitled to vote for the
                                  election of two additional directors to serve on the Board
                                  of Directors of the Company until all distribution
                                  arrearages are eliminated. See "Capital Stock -- PIERS --
                                  Voting Rights."

                           TAX STATUS OF THE COMPANY
 
    The Company has operated and intends to continue to operate so as to
continue to qualify, and will elect, to be taxed as a REIT under Sections 856
through 860 of the Code, commencing with its short taxable year ending December
31, 1997. The Company believes its organization and proposed method of operation
will enable it to continue to meet the requirements for qualifications as a
REIT. To maintain REIT status, an entity must meet a number of organizational
and operational requirements, including a requirement that it currently
distribute at least 95% of its REIT taxable income (computed without regard to
the Company's net capital gain and dividends paid deduction) to its
stockholders. As a REIT, the Company generally will not be subject to federal
income tax or net income it distributes currently to its stockholders. If the
Company fails to qualify as a REIT in any taxable year, it will be subject to
federal income tax at regular corporate rates. See "Material Federal Income Tax
Consequences" and "Risk Factors--Failure to Qualify as a REIT Would Cause the
Company to be Taxed as a Corporation; Other tax liabilities could adversely the
Company's cash flow." Even if the Company qualifies for taxation as a REIT, the
Company may be subject to certain federal, state and local taxes on its income
and property.

(1) Basic earnings per share excludes any dilutive effect of options
    outstanding. Diluted earnings per share includes the dilutive effect of the
    outstanding options calculated under the treasury stock method. As each Unit
    is redeemable for one share of Common Stock, the calculation of earnings per
    share upon redemption of the outstanding Units will be unaffected, as
    Unitholders and stockholders are entitled to equal distributions on a per
    Unit and per share basis in the net income of the Company. Pro forma basic
    and diluted income before extraordinary item reflect the preferred stock
    dividends and accretion. Pro forma diluted income per share before
    extraordinary item excludes the conversion of the PIERS as the conversion of
    these shares would be antidilutive.
 
(2) The White Paper on Funds from Operations approved by the Board of Governors
    of NAREIT in March 1995 defines Funds from Operations as net income (loss)
    (computed in accordance with GAAP), excluding gains (or losses) from debt
    restructuring and sales of properties, plus real estate related depreciation
    and amortization and after adjustments for unconsolidated partnerships and
    joint ventures. The Company believes that Funds from Operations is helpful
    to investors as a measure of the performance of an equity REIT because,
    along with cash flow from operating activities, financing activities and
    investing activities, it provides investors with an indication of the
    ability of the Company to incur and service debt, to make capital
    expenditures and to fund other cash needs. The Company computes Funds from
    Operations in accordance with standards established by NAREIT which may not
    be comparable to Funds from Operations reported by other REITs that do not
    define the term in accordance with the current NAREIT definition or that
    interpret the current NAREIT definition differently than the Company. Funds
    from Operations does not represent cash generated from operating activities
    in accordance with GAAP and should not be considered as an alternative to
    net income (determined in accordance with GAAP) as an indication of the
    Company's financial performance or to cash flow from operating activities
    (determined in accordance with GAAP) as a measure of the Company's
    liquidity, nor is it indicative of funds available to fund the Company's
    cash needs, including its ability to make cash distributions. For a
    reconciliation of net income and Funds from Operations, see "Management's
    Discussion and Analysis of Financial Condition and Results of
    Operations--Funds from Operations."

                                  RISK FACTORS
 
    An investment in the PIERS involves various risks. Prospective investors
should carefully consider the following information before making a decision to
purchase PIERS in the PIERS Offering.
 
THE COMPANY'S DEPENDENCE ON THE MIDTOWN MARKETS DUE TO LIMITED GEOGRAPHIC
  DIVERSIFICATION COULD ADVERSELY AFFECT THE COMPANY'S FINANCIAL PERFORMANCE
 
    The Properties are primarily located in midtown Manhattan. Like other office
markets, the Midtown Markets have experienced downturns in the past, including
most recently in the late 1980s and early 1990s, and future declines in the New
York metropolitan economy or the Midtown Markets could adversely affect the
Company's financial performance. The Company's financial performance and its
ability to make distributions to stockholders are therefore dependent on
conditions in the New York metropolitan economy and the Midtown Markets. The
Company's revenue and the value of its properties may be affected by a number of
factors, including the economic climate in metropolitan New York (which may be
adversely affected by business layoffs or downsizing, industry slowdowns,
relocations of businesses, changing demographics, increased telecommuting,
infra-structure quality, New York State and New York City budgetary constraints
and priorities and other factors) and conditions in the Midtown Markets (such as
oversupply of or reduced demand for office space). There can be no assurance as
to the continued growth of the New York metropolitan economy, the continued
strength of the Midtown Markets or the future growth rate of the Company.
 
RISK THAT PENDING ACQUISITIONS WILL NOT CLOSE
 
    The Company has executed contracts with respect to the acquisition of the
four Pending Acquisitions which are expected to close within 60 days after the
closing of the Offerings. While the Company has commenced its due diligence with
respect to the Pending Acquisitions, the acquisition contracts are subject to
customary closing conditions and no assurances can be made that the Company will
complete any of the Pending Acquisitions. In the event any of the Pending
Acquisitions are not acquired, there can be no assurance that the Company will
apply any remaining net proceeds from the Offerings towards other acquisitions
that meet the Company's acquisition criteria. If the Company is unable to close
the acquisition of a significant number of the Pending Acquisitions or to locate
additional available acquisitions after the Offerings, the Company's ability to
continue to make distributions could be adversely affected.
 
RISKS ASSOCIATED WITH RAPID GROWTH, THE RECENT ACQUISITION OF MANY OF THE NEW
  PROPERTIES AND THE LACK OF OPERATING HISTORY
 
    The Company is currently experiencing a period of rapid growth. As the
Company acquires additional properties, the Company will be subject to risks
associated with managing new properties, including lease-up and tenant
retention. In addition, the Company's ability to manage its growth effectively
will require it to successfully integrate its new acquisitions into its existing
management structure. No assurances can be given that the Company will be able
to succeed with such integration or effectively manage additional properties or
that newly acquired properties will perform as expected.
 
    All of the Acquired Properties have relatively short or no operating history
under management by the Company prior to their acquisition by the Company, and
none of the Pending Acquisitions are currently managed by the Company. The
Company has had limited control over the operation of the Acquired Properties
and the Pending Acquisitions, and such properties may have characteristics or
deficiencies unknown to the Company affecting their valuation or revenue
potential, and it is also possible that the operating performance of these
properties may decline under the Company's management.
 
    The Company is currently under contract to acquire three Class B office
properties encompassing 531,000 rentable square feet. See "Recent
Developments--Pending Acquisitions." In the future, the Company expects to
acquire additional office properties, including the three under contract. As
noted
 
                                       16
<PAGE>
above, acquisitions entail the risk that investments will fail to perform in
accordance with expectations, including operating and leasing expectations. The
Company anticipates that certain of its acquisitions will be financed using the
proceeds of periodic equity or debt offerings, lines of credit or other forms of
secured or unsecured financing that will result in a risk that permanent
financing for newly acquired projects might not be available or would be
available only on disadvantageous terms. If permanent debt or equity financing
is not available on acceptable terms to refinance acquisitions undertaken
without permanent financing, further acquisitions may be curtailed or cash
available for distribution may be adversely affected. In addition, it is
anticipated that acquisition risks may be heightened for acquisitions of
Manhattan office properties due to the large size of many Manhattan office
properties and the complexity of acquisition transactions in the Manhattan
office market.
 
THE MANAGING UNDERWRITER WILL RECIEVE $240 MILLION FROM THE NET PROCEEDS OF THE
  OFFERINGS
 
    An affiliate of Lehman Brothers, the lead managing underwriter of the
Offerings, will receive $240 million from the net proceeds of the Offerings in
repayment of the Acquisition Facility in addition to underwriting discounts and
commissions. Prudential Securities Incorporated will act as a "qualified
independent underwriter" in connection with the Offerings.
 
THE COMPANY'S PERFORMANCE AND VALUE ARE SUBJECT TO RISKS ASSOCIATED WITH THE
  REAL ESTATE INDUSTRY
 
    THE COMPANY'S ABILITY TO MAKE DISTRIBUTIONS IS DEPENDENT UPON THE ABILITY OF
ITS OFFICE PROPERTIES TO GENERATE INCOME IN EXCESS OF OPERATING EXPENSES.  Real
estate investments are subject to varying degrees of risk. The yields available
from equity investments in real estate and the Company's ability to service debt
depend in large part on the amount of income generated, expenses incurred and
capital expenditures required. The Company's distributable cash flow and ability
to continue to make distributions to its stockholders is dependent upon the
ability of its office properties to generate income in excess of its
requirements to meet operating expenses, including debt service and capital
expenditures. The Company's income from office properties and the value of its
properties may be significantly adversely affected by a number of factors,
including national, state and local economic climates and real estate conditions
(such as an oversupply of or a reduction in demand for office space in the area;
the perceptions of tenants and prospective tenants of the safety, convenience
and attractiveness of the Company's properties; the Company's ability to provide
adequate management, maintenance and insurance; the quality, philosophy and
performance of the Company's management; competition from comparable properties;
the occupancy rate of the Company's properties; the ability to collect on a
timely basis all rent from tenants; the effects of any bankruptcies or
insolvencies of major tenants; the expense of periodically renovating, repairing
and re-leasing space (including, without limitation, substantial tenant
improvement costs, capital improvement to properties and leasing costs of
re-leasing office space); and increasing operating costs (including increased
real estate taxes) which may not be passed through fully to tenants). In
addition, income from properties and real estate values also are affected by
such factors as the cost of compliance with laws, including zoning and tax laws,
the potential for liability under applicable laws, interest rate levels and the
availability of financing. Certain significant expenditures associated with
equity investments in real estate (such as mortgage payments, real estate taxes,
insurance and maintenance costs) also may not be reduced if circumstances cause
a reduction in income from a property. If any of the above occurred, the
Company's ability to continue to make distributions to its stockholders at
historical levels could be adversely affected.
 
    TENANT DEFAULTS AND BANKRUPTCIES COULD ADVERSELY AFFECT THE COMPANY'S CASH
FLOW.  Substantially all of the Company's income is derived from rental income
from its properties and, consequently, the Company's distributable cash flow and
ability to continue to make distributions to stockholders would be adversely
affected if a significant number of tenants at its properties failed to meet
their lease obligations. At any time, a tenant at a property in which the
Company has an interest may seek the protection of the bankruptcy laws, which
could result in delays in rental payments or in the rejection and termination of
such tenant's lease, thereby causing a reduction in the Company's cash flow and,
possibly, the amounts available
 
                                       17
<PAGE>
for distribution to stockholders. No assurance can be given that tenants will
not file for bankruptcy protection in the future or, if any tenants file, that
they will affirm their leases and continue to make rental payments in a timely
manner. In addition, a tenant from time to time may experience a downturn in its
business which may weaken its financial condition and result in the failure to
make rental payments when due. If tenant leases are not affirmed following
bankruptcy or if a tenant's financial condition weakens, the Company's cash flow
and continued ability to make distributions to its stockholders could be
adversely affected. While the Company and its predecessors have not experienced
any significant interruption of its cash flow due to tenant defaults in the past
five years, no assurance can be given that the Company will not experience
significant tenant defaults in the future.
 
    LEASE EXPIRATIONS COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW.  The
Company is subject to the risk that, upon expiration of leases for space located
in the Properties, these leases may not be renewed, the space may not be
re-leased or the terms of renewal or re-leasing (including the cost of required
renovations) may be less favorable than current lease terms. Leases on a total
of 10.2% and 7.5% of the total leased square feet at the Properties expire
during 1998 and 1999, respectively.
 
    ILLIQUIDITY OF REAL ESTATE INVESTMENTS COULD ADVERSELY AFFECT THE COMPANY'S
FINANCIAL CONDITION.  Real estate investments are relatively illiquid and,
therefore, will tend to limit the ability of the Company to sell and purchase
properties promptly in response to changes in economic or other conditions. In
addition, the Code places limits on the Company's ability to sell properties
held for fewer than four years, and the Lock-out Provisions (as defined herein)
impose certain special restrictions with respect to the sale of certain of the
Properties during the Lock-out Period (as defined herein). These considerations
could make it difficult for the Company to sell properties, even if a sale were
in the best interests of the Company's stockholders.
 
    OPERATING COSTS COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW.  The
Properties will be subject to operating risks common to commercial real estate
in general, any and all of which may adversely affect occupancy or rental rates.
The Properties are subject to increases in operating expenses such as cleaning;
electricity; heating, ventilation and air conditioning ("HVAC"); elevator repair
and maintenance; insurance and administrative costs; and other general costs
associated with security, repairs and maintenance. While the Company's tenants
generally are currently obligated to pay a portion of these escalating costs,
there can be no assurance that tenants will agree to pay such costs upon renewal
or that new tenants will agree to pay such costs. If operating expenses
increase, the local rental market may limit the extent to which rents may be
increased to meet increased expenses without decreasing occupancy rates. While
the Company implements cost saving incentive measures at each of its Properties,
if any of the above occurs, the Company's distributable cash flow and ability to
continue to make distributions to stockholders could be adversely affected.
 
    INVESTMENTS IN MORTGAGE LOANS COULD CAUSE EXPENSES WHICH COULD ADVERSELY
AFFECT THE COMPANY'S FINANCIAL CONDITION.  The Company owns a mortgage interest
in 17 Battery Place, which mortgage interest provides the Company with
substantially all control over and economic interest derived from such Property
and will hold a mortgage interest in a leasehold interest, in addition to other
interests held by the Company, in 711 Third Avenue subject to completion of that
Pending Acquisition. See "The Properties--17 Battery Place." To the extent the
Company invests in mortgage loans, such mortgage loans may or may not be
recourse obligations of the borrower and generally will not be insured or
guaranteed by governmental agencies or otherwise. In the event of a default
under such obligations, the Company may have to foreclose its mortgage or
protect its investment by acquiring title to a property and thereafter making
substantial improvements or repairs in order to maximize the property's
investment potential. Borrowers may contest enforcement of foreclosure or other
remedies, seek bankruptcy protection against such enforcement and/ or bring
claims for lender liability in response to actions to enforce mortgage
obligations. Relatively high "loan-to-value" ratios and declines in the value of
the property may prevent the Company from realizing an amount equal to its
mortgage loan upon foreclosure.
 
                                       18
<PAGE>
    JOINT INVESTMENTS COULD BE ADVERSELY AFFECTED BY THE COMPANY'S LACK OF SOLE
DECISION-MAKING AUTHORITY AND RELIANCE UPON A CO-VENTURER'S FINANCIAL
CONDITION.  The Company may co-invest with third parties through partnerships,
joint ventures, co-tenancies or other entities, acquiring non-controlling
interests in or sharing responsibility for managing the affairs of a property,
partnership, joint venture, co-tenancy or other entity and, therefore, will not
be in a position to exercise sole decision-making authority regarding the
property, partnership, joint venture or other entity. Investments in
partnerships, joint ventures, or other entities may, under certain
circumstances, involve risks not present were a third party not involved,
including the possibility that the Company's partners, co-tenants or
co-venturers might become bankrupt or otherwise fail to fund their share of
required capital contributions, that such partners or co-venturers might at any
time have economic or other business interests or goals which are inconsistent
with the business interests or goals of the Company, and that such partners,
co-tenants or co-venturers may be in a position to take action contrary to the
instructions or the requests of the Company and contrary to the Company's
policies or objectives. Such investments may also have the potential risk of
impasses on decisions, such as a sale, because neither the Company nor the
partner, co-tenant or co-venturer would have full control over the partnership
or joint venture. Consequently, actions by such partner, co-tenant or
co-venturer might result in subjecting properties owned by the partnership or
joint venture to additional risk. In addition, the Company may in certain
circumstances be liable for the actions of its third-party partners, co-tenants
or co-venturers. The Company will seek to maintain sufficient control of such
entities to permit it to achieve its business objectives.
 
    For instance, the interest of the Company in the Property at 17 Battery is
comprised of a co-tenancy interest in the co-tenancy that owns the land and
buildings, and a note and mortgage encumbering the interest of the other
co-tenant in the co-tenancy. Upon acquisition of the Property, a co-tenancy was
created between a subsidiary of the Company and 17 Battery Upper Partners LLC
("Upper"), an arm's length third party. Pursuant to the co-tenancy agreement,
the Company acts as managing and leasing agent for the entire property. The
economic risks and benefits of the lower thirteen (13) floors (excluding certain
portions of the ground floor) of the south building and the entire north
building are vested with the Company, and these risks and benefits for the
fourteenth and higher floors (together with certain tenanted areas of the ground
floor) of the south building are vested with Upper.
 
    The co-tenancy agreement contemplates the formation of a three unit
condominium. The co-tenancy interest of Upper will be converted to one unit and
the co-tenancy interest of the Company will be converted to the other two units.
It is the current intention of the Company to complete the condominium
organization process in the second quarter of 1998.
 
    In addition, the Company will have a co-tenancy interest in the feehold of
711 Third Avenue, among other interests, subject to completion of this Pending
Acquisition.
 
   
    THE EXPIRATION OF NET LEASES AND OPERATING SUBLEASES COULD ADVERSELY AFFECT
THE COMPANY'S FINANCIAL CONDITION. With respect to four of the Properties (35
West 43rd Street (a part of the Bar Building), 673 First Avenue, 1140 Avenue of
the Americas and the Graybar Building) and one Pending Acquisition (711 Third
Avenue), the Company holds or will hold, subject to completion of the Pending
Acquisitions, a long-term leasehold or operating sublease interest in the land
and the improvements. Accordingly, unless the Company can purchase the subject
real estate or extend the terms of these leases before their expiration, the
Company will lose its interest in the improvements and land upon expiration of
the leases, the remaining terms of which exceeds 82 years in the case of 35 West
43rd Street, 39 years in the case of 673 First Avenue, 18 years (with an option
to extend for a further 50 year term) in the case of 1140 Avenue of the
Americas, 31 years in the case of the Graybar Building and 25 years in the case
of 711 Third Avenue. The lease for 35 West 43rd Street contains a right of first
refusal (which will run for the benefit of the Company), to purchase fee title
to the land and building if the owner desires to sell its interest. The lease
for 673 First Avenue contains a right of first offer, whereby if the current fee
owner of the Property wishes to create a new underlying lease of the land and
building (the term of which would extend beyond the term of the existing
    
 
                                       19
<PAGE>
lease), then the Company has a right of first offer to enter into the new
underlying lease. See "The Properties."
 
   
    THE COMPANY'S FINANCIAL CONDITION COULD BE ADVERSELY AFFECTED DUE TO ITS
RELIANCE ON MAJOR TENANTS.  On a pro forma basis (giving effect to signed leases
in effect as of December 31, 1997) during the twelve months ended December 31,
1997, five tenants (City of New York, NYANA, Greenpoint Savings Bank, MetroNorth
and Dow Jones) each accounted for more than 2.0% of the Company's pro forma
total annualized rental revenues and such tenants collectively accounted for
approximately 12.5% of the Company's pro forma total annualized rental revenues.
See "The Properties--The Portfolio--Tenant Diversification." The Company would
be adversely affected in the event of a bankruptcy or insolvency of, or a
downturn in the business of, any major tenant which resulted in a failure or
delay in such tenant's rent payments.
    
 
THE COMPANY'S USE OF DEBT FINANCING, INCREASES IN INTEREST RATES, FINANCIAL
  COVENANTS AND ABSENCE OF LIMITATION ON DEBT COULD ADVERSELY AFFECT THE COMPANY
 
    THE REQUIRED REPAYMENT OF DEBT OR INTEREST THEREON COULD ADVERSELY AFFECT
THE COMPANY'S FINANCIAL CONDITION. The Company is subject to the risks normally
associated with debt financing, including the risk that the Company's cash flow
will be insufficient to meet required payments of principal and interest, the
risk of violating loan covenants, the risk of rising interest rates on the
Company's variable rate debt and the risk that the Company will not be able to
repay or refinance existing indebtedness on its properties at maturity (which
generally will not have been fully amortized at maturity) or that the terms of
such refinancing will not be as favorable as the terms of existing indebtedness.
There can be no assurance that the Company will be able to refinance any
indebtedness it may incur or otherwise obtain funds by selling assets or raising
equity to make required payments on indebtedness. In addition, the Company's
ability to sell certain Properties or refinance indebtedness encumbering such
Properties will be restricted by the Lock-Out Provisions.
 
    The outstanding principal amount of $240 million under the Acquisition
Facility will be paid from the proceeds of these Offerings. The Credit Facility
will remain committed but unused until the Acquisition Facility is repaid, at
which time, the Company will be in compliance with all financial covenants under
the Credit Facility and will, subject to continuing compliance with such
covenants, again be able to draw additional funds under such Credit Facility. In
addition, upon expiration of the term of the Credit Facility, it is anticipated
that the Operating Partnership will be required to obtain an extension or
renewal of the Credit Facility or refinance borrowings thereunder through the
issuance of debt or equity securities or alternative lending sources. There is
no guarantee that such extension or renewal will be obtained or obtained on
favorable terms. See "The Properties--Credit Facilities."
 
    If one or more properties are mortgaged to secure payment of indebtedness
and the Company is unable to generate funds to cover debt service, the mortgage
securing such properties could be foreclosed upon by, or such properties could
otherwise be transferred to, the mortgagee with a consequent loss of income and
asset value to the Company. Although no Property owned or controlled by the
Company or its predecessors has been subject to bankruptcy proceedings, during
the downturn in the real estate market in the late 1980s and early 1990s,
certain real estate assets (including one office property in Manhattan and one
office property in Hempstead, New York) owned by partnerships affiliated with
the Company's predecessors did not generate sufficient cash flow to service the
debt secured by such properties. As a result, the partnerships which owned these
properties have transferred or agreed to transfer the properties to the lenders
in satisfaction of the loans.
 
    RISING INTEREST RATES COULD ADVERSELY AFFECT THE COMPANY'S CASH
FLOW.  Advances under the Credit Facility will bear interest at a variable rate.
In addition, the Company may incur indebtedness in the future that also bears
interest at a variable rate or may be required to refinance its debt at higher
rates. Accordingly, increases in interest rates could increase the Company's
interest expense, which could adversely affect the Company's ability to continue
to make distributions to stockholders.
 
                                       20
<PAGE>
    THE COMPANY'S POLICY OF NO LIMITATION ON DEBT COULD ADVERSELY AFFECT THE
COMPANY'S CASH FLOW.  Upon completion of the Offerings, the debt to market
capitalization ratio ("Debt Ratio") of the Company will be approximately 10.8%
on a fully diluted basis. The Company currently has a policy of incurring debt
only if upon such incurrence the Company's Debt Ratio would be 50% or less.
However, the organizational documents of the Company do not contain any
limitation on the amount of indebtedness the Company may incur. Accordingly, the
Board of Directors could alter or eliminate this policy and would do so, for
example, if it were necessary in order for the Company to continue to qualify as
a REIT, or to provide capital for investment, if the Board of Directors
determines that such an action is in the best interests of the Company. If this
policy were changed, the Company could become more highly leveraged, resulting
in an increase in debt service that could adversely affect the Company's cash
available for distribution to stockholders and could increase the risk of
default on the Company's indebtedness. See "Policies with Respect to Certain
Activities--Financing Policies."
 
    The Company has established its debt policy relative to the total market
capitalization of the Company rather than relative to the book value of its
assets. The Company has used total market capitalization because it believes
that the book value of its assets (which to a large extent is the depreciated
original cost of real property, the Company's primary tangible assets) does not
accurately reflect its ability to borrow and to meet debt service requirements.
The market capitalization of the Company, however, is more variable than book
value, and does not necessarily reflect the fair market value of the underlying
assets of the Company at all times. The Company also will consider factors other
than market capitalization in making decisions regarding the incurrence of
indebtedness, such as the purchase price of properties to be acquired with debt
financing, the estimated market value of its properties upon refinancing and the
ability of particular properties and the Company as a whole to generate cash
flow to cover expected debt service.
 
THE ABILITY OF STOCKHOLDERS TO EFFECT A CHANGE OF CONTROL OF THE COMPANY IS
  LIMITED
 
    STOCK OWNERSHIP LIMITS IN THE CHARTER COULD INHIBIT CHANGES IN CONTROL.  In
order to maintain its qualification as a REIT, not more than 50% in value of the
outstanding capital stock of the Company may be owned, directly or indirectly,
by five or fewer individuals (as defined in the Code to include certain
entities) during the last half of a taxable year (other than the first year)
(the "Five or Fewer Requirement"). In order to protect the Company against the
risk of losing REIT status due to a concentration of ownership among its
stockholders, the Company's Articles of Incorporation (the "Charter") limits
ownership of the issued and outstanding Common Stock by any single stockholder
to 9.0% of the lesser of the number or value of the outstanding shares of Common
Stock from time to time (the "Ownership Limit"). See "Capital
Stock--Restrictions on Transfer." The Board of Directors can waive these
restrictions if evidence satisfactory to the Board of Directors and the
Company's tax counsel is presented that the changes in ownership will not then
or in the future jeopardize the Company's status as a REIT and the Board of
Directors otherwise decides such action is in the best interests of the Company.
These restrictions have been waived by the Board of Directors with respect to
three current stockholders. See "Principal Stockholders." Shares acquired or
transferred in breach of the limitation will be automatically transferred to a
trust for the exclusive benefit of one or more charitable organizations and the
purchaser-transferee shall not be entitled to vote or to participate in
dividends or other distributions. In addition, shares of Common Stock acquired
or transferred in breach of the limitation may be purchased from such trust by
the Company for the lesser of the price paid and the average closing price for
the ten trading days immediately preceding redemption. A transfer of shares to a
person who, as a result of the transfer, violates the Ownership Limit will be
void. See "Capital Stock--Restrictions on Transfer" for additional information
regarding the Ownership Limit.
 
    The Ownership Limit may have the effect of delaying, deferring or preventing
a transaction or a change in control of the Company that might involve a premium
price for the Common Stock or otherwise be in the best interests of the
stockholders. See "Capital Stock--Restrictions on Transfer."
 
                                       21
<PAGE>
    POTENTIAL EFFECTS OF STAGGERED BOARD COULD INHIBIT CHANGES IN CONTROL.  The
Company's Board of Directors is divided into three classes. The initial terms of
the first, second and third classes expire in 1998, 1999 and 2000, respectively.
Beginning in 1998, directors of each class will be chosen for three-year terms
upon the expiration of their current terms and each year one class of directors
will be elected by the stockholders. The staggered terms for directors may
reduce the possibility of a tender offer or an attempt to effect a change in
control of the Company, even if a tender offer or a change in control would be
in the best interests of the stockholders.
 
    FUTURE ISSUANCES OF COMMON STOCK COULD DILUTE EXISTING STOCKHOLDERS'
INTERESTS.  The Charter authorizes the Board of Directors to issue additional
shares of Common Stock without stockholder approval. Any such issuance could
have the effect of diluting existing stockholders' interests in the Company.
 
    ISSUANCES OF PREFERRED STOCK COULD INHIBIT CHANGES IN CONTROL.  The Charter
authorizes the Board of Directors to issue up to 25 million shares of preferred
stock, $.01 par value per share (the "Preferred Stock" and, together with the
Common Stock, the "Stock"), to reclassify unissued shares of Stock, and to
establish the preferences, conversion and other rights, voting powers,
restrictions, limitations and restrictions on ownership, limitations as to
dividends or other distributions, qualifications, and terms and conditions of
redemption for each such class or series of any Preferred Stock issued.
4,000,000 PIERS will be issued and outstanding as of the closing of the
Offerings.
 
    CERTAIN PROVISIONS OF MARYLAND LAW COULD INHIBIT CHANGES IN CONTROL.
Certain provisions of the Maryland General Corporation Law (the "MGCL") may have
the effect of inhibiting a third party from making an acquisition proposal for
the Company or of impeding a change in control of the Company under
circumstances that otherwise could provide the holders of shares of Common Stock
with the opportunity to realize a premium over the then-prevailing market price
of such shares. The Company has opted out of these provisions of the MGCL, but
the Board of Directors may elect to adopt these provisions in the future. See
"Certain Provisions of Maryland Law and the Company's Charter and ByLaws."

  SPACE COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW
 
    Many of the tenants in the Properties are smaller and growth-oriented
businesses that may not have the financial strength of larger corporate tenants.
Smaller companies generally experience a higher rate of failure than large
businesses. Growth-oriented firms may seek other office space, including Class A
space, as they develop. Dependence on these companies could create a higher risk
of tenant defaults and bankruptcies, which could adversely affect the Company's
distributable cash flow and ability to continue to make distributions to
stockholders.
 
CONFLICTS OF INTEREST IN CONNECTION WITH THE FORMATION TRANSACTIONS AND THE
  BUSINESS OF THE COMPANY
 
    A SALE OF, OR REDUCTION IN MORTGAGE INDEBTEDNESS ON, ANY OF THE PROPERTIES
WILL HAVE DIFFERENT EFFECTS ON HOLDERS OF UNITS THAN ON STOCKHOLDERS.  Certain
holders of Units, consisting of Stephen L. Green, members of his immediate
family and unaffiliated partners in the Property-owning entities, may experience
different and more adverse tax consequences compared to those experienced by
holders of shares of Common Stock or other holders of Units upon the sale of, or
reduction of mortgage indebtedness on, any of the Properties. Therefore, such
holders and the Company may have different objectives regarding the appropriate
pricing and timing of any sale of, or reduction of mortgage indebtedness on the
Properties, and regarding the appropriate characteristics of additional
properties to be considered for acquisition. Mr. Green and members of his
immediate family, are the holders of 2,140,784 Units, and their status as
holders of Units may influence the Company not to sell particular properties, or
not to pay down mortgage indebtedness on particular properties, even though such
sales or debt paydowns might otherwise be financially advantageous to the
Company and its stockholders. See "--Limitations on Ability to Sell or Reduce
the Mortgage Indebtedness on Certain Properties Could Adversely Affect the Value
of the Common Stock" below.
 
                                       22
<PAGE>
    FAILURE TO ENFORCE TERMS OF CONTRIBUTION AND OTHER AGREEMENTS.  As
affiliates of the Company's predecessors (which owned certain of the Properties
acquired by the Company in the Formation Transactions), and recipients of Units
in the Formation Transactions, certain members of the Company's management,
including Mr. Green, have a conflict of interest with respect to their
obligations as directors or executive officers of the Company in enforcing the
terms (including customary representations and warranties as to ownership and
operations) of the contribution agreements relating to the transfer to the
Company of their interests in the Properties' assets. The failure to enforce the
material terms of those agreements, particularly the indemnification provisions
for breaches of representations and warranties, could result in a monetary loss
to the Company, which loss could have a material adverse effect on the Company's
financial condition or results of operations. In addition, the aggregate
liability of Mr. Green and other members of management under those agreements is
limited to approximately $20 million (the initial value of the Units received by
them in the Formation Transactions based on the IPO price of the Common Stock)
with no liability being assumed until the aggregate liability exceeds $250,000.
In addition, Stephen L. Green, David J. Nettina, Nancy A. Peck, Steven H. Klein,
Benjamin P. Feldman, Gerard Nocera and Louis A. Olsen have entered into
employment and noncompetition agreements with the Company pursuant to which they
have agreed, among other things, not to engage in certain business activities in
competition with the Company. See "Management--Employment and Noncompetition
Agreements." To the extent that the Company chooses to enforce its rights under
any of these contribution, employment and noncompetition agreements, it may
determine to pursue available remedies, such as actions for damages or
injunctive relief, less vigorously than it otherwise might because of its desire
to maintain its ongoing relationship with the individual involved.
 
    CONFLICTS OF INTEREST WITH AFFILIATES OF THE COMPANY.  Two entities owned by
a son of Stephen L. Green (First Quality Maintenance, L.P. and Classic Security
LLC) currently provide cleaning and security services to office properties,
including the Company's Properties. See "Certain Relationships and
Transactions-- Cleaning Services" and "--Security Services." Although management
believes, based on its knowledge of the Class B Manhattan office market, that
the terms and conditions of the contracts pursuant to which these services are
provided are not less favorable to the Company than those which could be
obtained from a third party-providing comparable services, such contracts are
not the result of arm's length negotiations and, therefore, there can be no
assurance to this effect. The Company has adopted certain policies relating to
conflicts of interest. These policies include a resolution adopted by the
Company's Board of Directors which requires all transactions in which executive
officers or directors have a material conflicting interest to that of the
Company to be approved by a majority of the disinterested directors or by the
holders of a majority of the shares of Common Stock held by disinterested
stockholders. There can be no assurance, however, that the Company's policies
will be successful in eliminating the influence of such conflicts, and if they
are not successful, decisions could be made that might fail to reflect fully the
interests of all stockholders. See "Policies with Respect to Certain
Activities--Conflict of Interest Policies."
 
    OUTSIDE INTERESTS OF OFFICERS AND DIRECTORS COULD CONFLICT WITH THE
COMPANY'S INTERESTS.  Certain officers and directors of the Company own direct
and indirect interests in office properties and other real estate assets, which
interests may give rise to certain conflicts of interest concerning the
fulfillment of their responsibilities as officers and directors of the Company.
For a discussion of the role of the Company's disinterested directors and the
Company's policies and agreements designed to minimize any adverse effects from
these conflicts of interest, see "Policies with Respect to Certain
Activities--Conflict of Interest Policies."
 
LIMITATIONS ON ABILITY TO SELL OR REDUCE THE MORTGAGE INDEBTEDNESS ON CERTAIN
  PROPERTIES COULD ADVERSELY AFFECT THE VALUE OF THE COMMON STOCK AND THE PIERS
 
    In connection with the solicitation of approval of partners or members in
the various Property-owning entities to transfer their interests to the Company
at the time of the IPO, the Company agreed to certain restrictions relating to
future capital transactions involving two of the Properties. Pursuant to the
Lock-out Provisions, the Company may not sell its interest in (except in certain
events, including certain transactions
 
                                       23
<PAGE>
that would not result in the recognition of any gain for tax purposes) or,
earlier than one year prior to its maturity, reduce the mortgage indebtedness
(other than pursuant to scheduled amortization) on 673 First Avenue or 470 Park
Avenue South during the Lock-out Period without, in the case of each such
Property, the consent of holders of 75% of the Units originally issued to
limited partners in the Operating Partnership (including Stephen L. Green,
members of his immediate family and unaffiliated partners in the Property-owning
entities) who immediately prior to completion of the Formation Transactions
owned direct or indirect interests in such Property that remain outstanding at
the time of such vote (other than Units held by the Company and Units the
adjusted tax basis of which have been increased to reflect fair market value
through a taxable disposition or otherwise). (This vote requirement does not
apply to a sale of all or substantially all of the assets of the Operating
Partnership, but such a transaction during the Lock-out Period generally would
require the approval of the holders, as a group, of 75% of the aggregate Units
originally issued with respect to 673 First Avenue and 470 Park Avenue South
that remain outstanding (excluding Units held by the Company and Units the
adjusted tax basis of which have been increased to reflect fair market value
through a taxable disposition or otherwise) unless the transaction would not
result in the recognition of any gain for tax purposes with respect to such
Units and certain other conditions are satisfied.) In addition, during the
Lock-out Period, the Company is obligated to use commercially reasonable
efforts, commencing one year prior to the stated maturity, to refinance at
maturity (on a basis that is nonrecourse to the Operating Partnership and the
Company, with the least amount of principal amortization as is available on
commercially reasonable terms) the mortgage indebtedness secured by each of
these two Properties at not less than the principal amount outstanding on the
maturity date. Finally, during the Lock-out Period, the Company may not incur
debt secured by either of these two Properties if the amount of the new debt
would exceed the greater of 75% of the value of the Property securing the debt
or the amount of existing debt being refinanced (plus costs associated
therewith). Thus, the Lock-out Provisions materially restrict the Company from
selling or otherwise disposing of its interest in, or refinancing indebtedness
encumbering, 673 First Avenue and 470 Park Avenue South without obtaining such
consents. The Lock-out Provisions apply even if it would otherwise be in the
best interest of the stockholders for the Company to sell its interest in these
two Properties, reduce the outstanding indebtedness with respect to either of
these Properties or not refinance such indebtedness on a nonrecourse basis at
maturity, or increase the amount of indebtedness with respect to these two
Properties.
 
    The Lock-out Provisions may impair the ability of the Company to take
actions during the Lock-out Period that would otherwise be in the best interests
of the Company's stockholders and, therefore, may have an adverse impact on the
value of the Common Stock and the PIERS (relative to the value that would result
if the Lock-out Provisions did not exist). In particular, the Lock-out
Provisions could preclude the Operating Partnership (and thus the Company) from
participating in certain major transactions that could result in a disposition
of the Operating Partnership's assets or a change in control of the Company that
would result in the recognition of gain with respect to the holders of Units
issued with respect to 673 First Avenue or 470 Park Avenue South even though
such disposition or change in control might be in the best interests of the
stockholders. See "Partnership Agreement--Operational Matters--Sales of Assets."
 
    The Company anticipates that, in connection with future acquisitions of
interests in properties in which the Company uses Units as consideration, the
Company may agree to limitations on its ability to sell, or reduce the amount of
mortgage indebtedness on, such acquired properties, which may increase the
Company's leverage. Such limitations may impair the Company's ability to take
actions that would otherwise be in the best interests of its stockholders and,
therefore, may have an adverse impact on the value of the Common Stock and the
PIERS (relative to the value that would result if such limitations did not
exist). Such possible future limitations, together with the Lock-out Provisions,
may restrict the ability of the Company to sell substantially all of its assets,
even if such a sale would be in the best interests of its stockholders.

FAILURE TO QUALIFY AS A REIT WOULD CAUSE THE COMPANY TO BE TAXED AS A
  CORPORATION
 
    The Company has operated and intends to continue to operate so as to qualify
as a REIT under the Code, commencing with its taxable year ending December 31,
1997. Although management believes that the Company is and will continue to be
organized and has operated and will continue to operate in such a manner, no
assurance can be given that the Company is now or will continue to be organized
or operated in a manner so as to qualify or remain so qualified. Qualification
as a REIT involves the satisfaction of numerous requirements (some on an annual
and quarterly basis) established under highly technical and complex Code
provisions for which there are only limited judicial and administrative
interpretations, and involves the determination of various factual matters and
circumstances not entirely within the Company's control. For example, in order
to qualify as a REIT, at least 95% of the Company's gross income in any year
must be derived from qualifying sources and the Company must pay distributions
to stockholders aggregating annually at least 95% of its REIT taxable income
(excluding capital gains). The complexity of these provisions and of the
applicable Treasury Regulations that have been promulgated under the Code is
greater in the case of a REIT that holds its assets in partnership form. No
assurance can be given that legislation, new regulations, administrative
interpretations or court decisions will not significantly change the tax laws
with respect to qualification as a REIT or the federal income tax consequences
of such qualification. The Company, however, is not aware of any pending
legislation that would adversely affect the Company's ability to operate as a
REIT. Brown & Wood LLP, counsel to the Company, will render an opinion to the
effect that commencing with its taxable year ended December 31, 1997, the
Company has been organized and has operated in conformity with the requirements
for qualification and taxation as a REIT, and that the Company's proposed method
of operation will enable it to continue to meet the requirements for
qualifications and taxation as a REIT. See "Material Federal Income Tax
Consequences--Taxation of the Company." Such legal opinion is based on various
assumptions and factual representations by the Company regarding the Company's
ability to meet the various requirements for qualification as a REIT, and no
assurance can be given that actual operating results will meet these
requirements. The opinion of Brown & Wood LLP is not binding on the IRS or any
court. Moreover, the Company's qualification and taxation as a REIT depend on
the Company's ability to meet (through actual annual operating results,
distribution levels and diversity of stock ownership) the various qualification
tests imposed under the Code, the results of which will not be reviewed by tax
counsel to the Company.
 
    If the Company were to fail to qualify as a REIT in any taxable year, the
Company would be subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at regular corporate rates.
Moreover, unless entitled to relief under certain statutory provisions, the
Company also would be disqualified from treatment as a REIT for the four taxable
years following the year during which qualification was lost. This treatment
would significantly reduce the net earnings of the Company available for
investment or distribution to stockholders because of the additional tax
liability to the Company for the years involved. In addition, distributions to
stockholders would no longer be required to be made. See "Material Federal
Income Tax Consequences--Taxation of the Company--Requirements for
Qualification."
 
COMPETITION IN ITS MARKETPLACE COULD HAVE AN ADVERSE IMPACT ON THE COMPANY'S
  RESULTS OF OPERATIONS
 
    All of the Properties are located in highly developed areas of Manhattan
that include a large number of other office properties. Manhattan is by far the
largest office market in the United States and contains more rentable square
feet than the next six largest central business district office markets in the
United States combined. Of the total inventory of 379 million rentable square
feet in Manhattan, approximately 172 million rentable square feet is comprised
of Class B office space and 207 million rentable square feet is comprised of
Class A office space. Class A office properties are generally newer than Class B
office properties, have higher finishes and command higher rental rates. Many
tenants have been attracted to Class B properties in part because of their
relatively less expensive rental rates (as compared to Class A
 
                                       25
<PAGE>
properties) and the tightening of the Class A office market in midtown
Manhattan. See "Market Overview." Consequently, an increase in vacancy rates
and/or a decrease in rental rates for Class A office space would likely have an
adverse effect on rental rates for Class B office space. Also, the number of
competitive Class B office properties in Manhattan (some of which are newer and
better located) could have a material adverse effect on the Company's ability to
lease office space at its properties, and on the effective rents the Company is
able to charge.
 
    In addition, the Company competes with other property owners that have
greater resources than the Company. In particular, although currently no other
publicly traded REITs have been formed solely to own, operate and acquire
Manhattan Class B office properties, the Company may in the future compete with
such other REITs. In addition, the Company may face competition from other real
estate companies (including other REITs that currently invest in markets other
than Manhattan) that have greater financial resources than the Company or that
are willing to acquire properties in transactions which are more highly
leveraged than the Company is willing to undertake. The Company also faces
competition from other real estate companies that provide management, leasing,
construction and other services similar to those to be provided by the Service
Corporations. In addition, certain requirements for REIT qualification may in
the future limit the Company's ability to increase operations conducted by the
Service Corporations without jeopardizing the Company's qualification as a REIT.
See "Material Federal Income Tax Consequences-- Other Tax
Considerations--Service Corporations."
 
THE FINANCIAL CONDITION OF THIRD-PARTY PROPERTY MANAGEMENT, LEASING AND
  CONSTRUCTION BUSINESSES COULD ADVERSELY AFFECT THE COMPANY'S FINANCIAL
  CONDITION
 
    The Company is subject to the risks associated with the management, leasing
and construction businesses that will be conducted by the Service Corporations
(as defined herein), in which the Operating Partnership holds a 95% economic
interest. These risks include the risk that management and leasing contracts
with third party property owners will not be renewed upon expiration (or will be
canceled pursuant to cancellation options) or will not be renewed on terms at
least as favorable to the Company as current terms, that the rental revenues
upon which management, leasing and construction fees are based will decline as a
result of general real estate market conditions or specific market factors
affecting properties serviced by the Company, and that leasing and construction
activity generally will decline. Since the IPO, 10 management and leasing
contracts with third party property owners have been cancelled, representing an
aggregate of approximately $2.0 million in annual revenue. In order to focus on
the management and leasing of its own Properties, the Company does not intend to
seek to replace the contracts or to pursue other third party management and
leasing opportunities. Each of these developments could adversely affect the
revenues of S.L. Green Managment Corp. (the "Management Corporation"), S.L.
Green Leasing, Inc. (the "Leasing Corporation") and Emerald City Construction
Corp. (the "Construction Corporation"), the Companies that conduct the
management, leasing and construction businesses, respectively, with respect to
properties in which the Company has no ownership interest, and could adversely
affect the ability of the Company to continue to make expected distributions to
its stockholders.
 
    In order to maintain its qualification as a REIT, the Company does not have
voting control over the Management Corporation, the Leasing Corporation or the
Construction Corporation (together, the "Service Corporations"). The Service
Corporation LLC owns 100% of the voting common stock (representing 5% of the
economic interest) of each of the Service Corporations. As a result, the Company
does not have the ability to elect or remove any members of the board of
directors of the Management Corporation, the Leasing Corporation or the
Construction Corporation, and, therefore, its ability to influence the
day-to-day decisions of the Service Corporations is limited. As a result, the
boards of directors or management of the Service Corporations may implement
business policies or decisions that might not have been implemented by persons
elected by the Company and that are adverse to the interests
 
                                       26
<PAGE>
of the Company or that lead to adverse financial results, which could adversely
affect the ability of the Company to make expected distributions to the
Company's stockholders.
 
LIABILITY FOR ENVIRONMENTAL MATTERS COULD ADVERSELY AFFECT THE COMPANY'S
  FINANCIAL CONDITION
 
    Under various Federal, state and local laws, ordinances and regulations, a
current or previous owner or operator of real estate may be required to
investigate and clean up certain hazardous substances released at a property,
and may be held liable to a governmental entity or to third parties for property
damage or personal injuries and for investigation and clean-up costs incurred by
the parties in connection with any contamination. In addition, some
environmental laws create a lien on a contaminated site in favor of the
government for damages and costs it incurs in connection with the contamination.
Such laws often impose such liability without regard to whether the owner or
operator knew of, or was responsible for, the release of hazardous substances.
The cost of any required remediation and the owner's liability therefore as to
any property is generally not limited under such enactments and could exceed the
value of the property and/or the aggregate assets of the owner. The presence of
contamination or the failure to remediate contamination may adversely affect the
owner's ability to sell or lease real estate or to borrow using the real estate
as collateral. No assurances can be given that (i) a prior owner, operator or
occupant, such as a tenant, did not create a material environmental condition
not known to the Company, (ii) a material environmental condition with respect
to any Property does not exist, or (iii) future uses or conditions (including,
without limitation, changes in applicable environmental laws and regulations)
will not result in the imposition of environmental liability.
 
    The Company engaged independent environmental consulting firms to perform
Phase I environmental site assessments on the Properties (except 633 Third
Avenue and 17 Battery Place) and on the Pending Acquisitions in order to assess
existing environmental conditions. All of the Phase I assessments have been
conducted since or after March 1997, except for the Bar Building, where a Phase
I assessment was conducted in September 1996. Additionally, a Phase I assessment
on 17 Battery Place was conducted on behalf of a prior owner in December 1995.
Such owner retained SL Green as property manager and leasing agent in January
1996 and SL Green or the Company has operated a management office on-site since
such date. All of the Phase I assessments met the requirements of the American
Society for Testing and Materials ("ASTM") Standard Practice for Phase I
Environmental Site Assessments (the "ASTM Standard"). Under the ASTM Standard, a
Phase I environmental site assessment consists of a site visit, a historical
record review, a review of regulatory agency data bases and records, interviews,
and a report, with the purpose of identifying potential environmental concerns
associated with real estate. The Phase I assessments conducted at the Properties
also addressed certain issues that are not covered by the ASTM Standard,
including asbestos, radon, lead-based paint and lead in drinking water. These
environmental site assessments did not reveal any known environmental liability
that the Company believes will have a material adverse effect on the Company's
financial condition or results of operations or would represent a material
environmental cost, nor is the Company aware of any such material environmental
liability. The Company as a matter of policy conducts Phase I environmental site
assessments on all new acquisitions prior to completing any transaction. See
"The Properties--Environmental Matters."
 
                                       27

LACK OF PUBLIC MARKET FOR THE PIERS
 
    The PIERS are a new issue of securities for which there is currently no
active trading market. If the PIERS are traded after their initial issuance,
they may trade at a discount from their initial offering price, depending upon
prevailing interest rates, the market for similar securities, the financial
condition and performance of the Company and other factors beyond the control of
the Company, including general economic conditions.
 
OTHER RISKS OF OWNERSHIP OF COMMON STOCK AND PIERS COULD ADVERSELY AFFECT THE
  TRADING PRICE
  OF THE COMMON STOCK AND OF THE PIERS
 
    AVAILABILITY OF SHARES FOR FUTURE SALE COULD ADVERSELY AFFECT THE PRICE OF
THE COMMON STOCK AND THE PIERS. Sales of a substantial number of shares of
Common Stock, or the perception that such sales could occur, could adversely
affect prevailing market prices of the Common Stock and of the PIERS. Beginning
on August 20, 1999 (or sooner in certain circumstances), holders of Units may be
able to sell shares of Common Stock received upon exercise of their redemption
right in the public market pursuant to registration or available exemptions from
registration. Additionally, holders of PIERS will be able to sell shares of
Common Stock they will receive upon exercise of the conversion rights in the
public market. Furthermore, a substantial number of shares of Common Stock will,
pursuant to employee benefit plans, be issued or reserved for issuance from time
to time, including shares of Common Stock reserved for issuance pursuant to
options issued concurrently with the completion of the Offering, and these
shares of Common Stock will be available for sale in the public market from time
to time pursuant to exemptions from registration or upon registration. No
prediction can be made about the effect that future sales of shares of Common
Stock will have on the market price of the Common Stock or the PIERS.
 
    CHANGES IN MARKET INTEREST RATES COULD ADVERSELY AFFECT THE PRICE OF COMMON
STOCK AND OF THE PIERS.  One of the factors that influences the price of both
the Common Stock and the PIERS is the dividend yield on such stock (as a
percentage of the price of such stock) relative to market interest rates. Thus,
an increase in market interest rates may lead prospective purchasers of stock to
expect a higher dividend yield, which may adversely affect the market price of
the price of the Common Stock and of the PIERS.
 
    UNRELATED EVENTS COULD ADVERSELY AFFECT THE PRICE OF COMMON STOCK AND OF THE
PIERS.  As with other publicly traded equity securities, the value of the Common
Stock and of the PIERS depends upon various market conditions, including
conditions unrelated to the New York metropolitan economy, the Manhattan office
market or real estate investments generally. Thus, events which depress equity
market prices may not have any effect on real estate market values, and shares
of Common Stock may trade at prices below the Company's net asset value and the
PIERS may trade below their liquidation preference.
 
    THE OFFICERS, DIRECTORS AND SIGNIFICANT STOCKHOLDERS OF THE COMPANY HAVE
SUBSTANTIAL INFLUENCE.  Upon the completion of the Offerings, approximately 9.6%
of the equity in the Company will be beneficially owned by officers and
directors of the Company, on a fully diluted basis. See "Principal
Stockholders." In addition, Stephen L. Green and Benjamin P. Feldman serve on
the Board of Directors of the Company. Accordingly, such persons have
substantial influence on the Company, which influence may not be consistent with
the interests of other stockholders, and may in the future have a substantial
influence on the outcome of any matters submitted to the Company's stockholders
for approval if all or a significant number of their Units are exchanged for
shares of Common Stock. In addition, although there is no current agreement,
understanding or arrangement for these stockholders to act together on any
matter, these stockholders would be in a position to exercise significant
influence over the affairs of the Company if they were to act together in the
future.
 
                                       28
<PAGE>
THE COMPANY RELIES ON KEY PERSONNEL WHOSE CONTINUED SERVICE IS NOT GUARANTEED
 
    The Company is dependent on the efforts of its executive officers, Stephen
L. Green, Nancy A. Peck, David J. Nettina, Steven H. Klein, Benjamin P. Feldman,
Gerard Nocera and Louis A. Olsen. The loss of their services could have a
material adverse effect on the operations of the Company. Mr. Green has
interests in various properties in Manhattan and a property located in
Pennsylvania. It is expected that Mr. Green will not devote a substantial amount
of time to the management or operation of these other properties. Prior to the
completion of the IPO, each of the executive officers, including Mr. Green,
entered into an employment and noncompetition agreement with the Company which
provide, among other items, that each such person will devote substantially all
of his or her business time to the Company but excepts the excluded assets
referred to above from the noncompetition provisions thereof. See "Management--
Employment and Noncompetition Agreements."
 
STOCKHOLDER APPROVAL IS NOT REQUIRED TO CHANGE POLICIES OF THE COMPANY
 
    The investment, financing, borrowing and distribution policies of the
Company and its policies with respect to all other activities, including
qualification as a REIT, growth, debt, capitalization and operations, are
determined by the Board of Directors. Although it has no present intention to do
so, the Board of Directors may amend or revise these policies at any time and
from time to time at its discretion without a vote of the stockholders of the
Company. A change in these policies could adversely affect the Company's
financial condition, results of operations or the market price of the Common
Stock.
 
UNINSURED LOSSES COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW
 
    The Company carries comprehensive liability, fire, flood, extended coverage
and rental loss (for rental losses extending up to 12 months) with respect to
the Properties with policy specifications and insured limits customarily carried
for similar properties. Certain types of losses (such as from wars,
environmental hazards and employee discrimination claims), however, may be
either uninsurable or not economically insurable. Should an uninsured loss or a
loss in excess of insured limits occur, the Company could lose both its capital
invested in, and anticipated profits from, one or more of the Properties, and
may continue to be obligated on the mortgage indebtedness or other obligations
related to the property. Any such loss may adversely affect the business of the
Company and its financial condition and results of operations.
 
    New owner's title insurance policies were not obtained for one of the
Properties (1414 Avenue of the Americas) in connection with the Formation
Transactions. The Property is covered by existing title insurance policies
insuring the interests of the Property-owning entities. Further, the title
insurance policy covering such Property is for an amount which is less than the
current value of the Property. In the event of a loss with respect to a Property
relating to a title defect that is in excess of the amount of such title
insurance policy, the Company could lose both its capital invested in and
anticipated profits from such Property.
 
THE COSTS OF COMPLIANCE WITH THE AMERICANS WITH DISABILITIES ACT AND SIMILAR
  LAWS COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW
 
    AMERICANS WITH DISABILITIES ACT.  Under the Americans with Disabilities Act
of 1980 (the "ADA"), places of public accommodation and commercial facilities
are required to meet certain Federal requirements related to access and use by
disabled persons. These requirements became effective in 1992. Although
management of the Company believes that the Properties are substantially in
compliance with present requirements of the ADA, the Company may incur
additional costs of compliance in the future. A number of additional Federal,
state and local laws exist which impose further burdens or restrictions on
owners with respect to access by disabled persons and may require modifications
to the Properties owned by the Company, or restrict certain further renovations
thereof, with respect to access by disabled persons. Final regulations under the
ADA have not yet been promulgated and the ultimate amount of the cost
 
                                       29
<PAGE>
compliance with the ADA or other such laws is not currently ascertainable. While
such costs are not expected to have a material effect on the Company, they could
be substantial. If required changes involve greater expense than the Company
currently anticipates, the Company's ability to make distributions at historical
levels could be adversely affected.
 
    OTHER LAWS.  The Properties are also subject to various Federal, state and
local regulatory requirements, such as state and local fire and life safety
requirements. Failure to comply with these requirements could result in the
imposition of fines by governmental authorities or awards of damages to private
litigants. The Company believes that the Properties and the Pending Acquisitions
are currently in compliance with all such regulatory requirements. However,
there can be no assurance that these requirements will not be changed or that
new requirements will not be imposed which would require significant
unanticipated expenditures by the Company and could have an adverse effect on
the Company's Funds from Operations and expected distributions.

                                  THE COMPANY
 
    The Company is the first fully integrated, self-administered and
self-managed equity REIT solely engaged in owning, managing, leasing, acquiring
and repositioning Class B office properties in Manhattan. The Company continues
to be the only Class B office REIT in New York City. The Company currently owns
interests in 15 Class B office properties (the "Properties") containing
approximately 5.0 million rentable square feet located in Manhattan. As of April
24, 1998, the Company had entered into agreements to purchase four additional
office properties (the "Pending Acquisitions") containing an aggregate of
approximately 1,055,000 rentable square feet for an aggregate purchase price of
$111.0 million. As of December 31, 1997, the Properties were 90% leased. In
addition, the Company acts as leasing agent and/or manages 27 properties
(including the Properties owned by the Company) encompassing approximately 8.2
million rentable square feet.
 
    The term "Class B" is generally used in the Manhattan office market to
describe office properties which are more than 25 years old but which are in
good physical condition, enjoy widespread acceptance by high-quality tenants and
are situated in desirable locations in Manhattan. Class B office properties can
be distinguished from Class A properties in that Class A properties are
generally newer properties with higher finishes and obtain the highest rental
rates within their markets.
 
    A variety of tenants who do not require, desire or cannot afford Class A
space are attracted to Class B office properties due to their prime locations,
excellent amenities, distinguished architecture and relatively less expensive
rental rates. Class B office space has historically attracted many smaller
growth oriented firms (many of which have fueled the recent growth in the New
York metropolitan economy) and has played a critical role in satisfying the
space requirements of particular industry groups in Manhattan, such as the
advertising, apparel, business services, engineering, not-for-profit, new media
and publishing industries. In addition, several areas of Manhattan, including
many in which particular trades or industries traditionally congregate, are
dominated by Class B office space and contain no or very limited Class A office
space. Examples of such areas include the Garment District (where three of the
Properties are located), the Flatiron District (where one Property is located),
Soho, Noho, Chelsea (where one Property is located), and the area surrounding
the United Nations (where one Property is located). Businesses significantly
concentrated in certain of these areas include those in the following
industries: new media, garment, apparel, toy, jewelry, interior decoration,
antiques, giftware, contract furnishing and UN-related businesses. The
concentration of businesses creates strong demand for the available Class B
office space in those locations.
 
    As described herein, current developments in the New York economy provide an
attractive environment for owning, operating and acquiring Class B office
properties in Manhattan. See "Business and Growth Strategies--The Market
Opportunity" and "Risk Factors--The Company's Dependence on the Midtown Markets
Due to Limited Geographic Diversification Could Adversely Affect the Company's
Financial Performance." These developments have resulted in growing demand for
midtown Manhattan office space (particularly Class B space), declining vacancy
rates (the Class B vacancy rate in the Midtown Markets declined from 17.2% at
year-end 1992 to 9.8% at March 31, 1998) and appreciation in rental rates and
property values. The Company believes there will be a continued strengthening of
the Class B office market driven by expected job growth in Manhattan,
particularly among smaller companies which are, in many instances, Class B
tenants. Additionally, the Company believes that a number of high quality
tenants will likely seek to relocate from Class A space to Class B space in the
Midtown Markets as a result of the rising cost of Class A space. The Company
seeks to capitalize on growth opportunities in its marketplace by acquiring
Class B office properties on a selective basis and, when necessary, enhancing
their value after acquisition through repositioning of the properties in their
respective submarkets. As described more fully below, the Company may have
certain competitive advantages over other potential acquirors of Class B
Manhattan office space due to its local market expertise, long-term
relationships with brokers and property owners as a result of its property
management and leasing businesses, enhanced access to capital as a public
company and ability to offer tax-advantaged acquisition structures.
Additionally, the Company will seek to optimize its properties' cash flow
through ongoing intensive management and leasing. See "Business and Growth
Strategies--Growth Strategies."
 
    The Company has offices in midtown Manhattan and employs approximately 331
persons, including professionals with experience in all aspects of commercial
real estate. In addition to Stephen L. Green, the

Company has six senior executives that average more than seven years with SL
Green and more than 19 years in the commercial real estate business. This
management team has developed a comprehensive knowledge of the Manhattan Class B
office market, an extensive network of tenant and other business relationships
and experience in acquiring underperforming office properties and repositioning
them into profitable Class B properties through intensive full service
management and leasing efforts. Upon completion of the Offering, approximately
9.6% of the equity of the Company, on a fully diluted basis, will be
beneficially owned by officers and directors of the Company.
 
    The Company was incorporated in the State of Maryland on June 10, 1997. Its
executive offices are located at 70 West 36th Street, New York, New York

PENDING ACQUISITIONS
 
    As of April 24, 1998, the Company had executed contracts to acquire four
additional office properties containing approximately 1,055,000 rentable square
feet for an aggregate purchase price of approximately $111.0 million. The
Company intends to use a portion of the net proceeds from the Offerings to
complete the Pending Acquisitions within 60 days after the closing of the
Offerings, with the remainder of the purchase price funded through borrowings
under its Credit Facility; however, purchase of the Pending Acquisitions is
subject to the Company's completion of due diligence and the satisfaction of
other customary conditions to closing, and there can be no assurance that any of
the Pending Acquisitions will be completed. See "Risk Factors--Risk that Pending
Acquisitions Will Not Close." In addition to the Pending Acquisitions, as part
of its ongoing business, the Company continually engages in discussions with
various property owners regarding possible portfolio or single asset
acquisitions. No assurance can be made that the Company will acquire any of the
property opportunities currently under review. The following table sets forth

CREDIT FACILITIES
 
    On December 19, 1997 the Company entered into the $140 million Credit
Facility due December 2000. Availability under the Credit Facility may be
limited to an amount less the $140 million. Availability is calculated by
reference to several factors including recent acquisition activity and most
recent quarterly property performance. Outstanding loans under the Credit
Facility bear interest at a rate per annum equal to LIBOR applicable to each
interest period plus 130 basis points to 145 basis points per annum. The Credit
Facility requires the Company to comply with certain covenants, including but
not limited to, maintenance of certain financial ratios. At December 31, 1997
the outstanding amount of indebtedness under the Credit Facility was $76
million, and the interest rate on such indebtedness was 7.265% per annum.
 
    On December 30, 1997 the Company entered into a $7 million additional
advance under its existing mortgage loan which is secured by 50 West 23rd
Street. The note bore interest at a rate of LIBOR plus 175 basis points (7.6875%
at December 31, 1997). On April 3, 1998, the interest rate on this note was
fixed at 7.06%, and will mature co-terminous with the underlying mortgage note.
As of April 15, 1998, the current amount of the mortgage note was $21 million.
 
    On March 18, 1998, the Company asked the Credit Facility banking group to
temporarily relieve the Company from its obligations under the financial
covenants of the Credit Facility, in order to close the Acquisition Facility.
The Acquisition Facility, with a borrowing capacity of up to $275 million
financed the purchase of the Helmsley Properties, paid off the outstanding
balance on the Credit Facility and to provide ongoing liquidity for future
acquisition and corporate needs. The term of this loan is one year. The interest
rate is determined by a schedule of the principal balance of the loan
outstanding and the applicable quarterly period extending from March 18, 1998
through the maturity date. The outstanding principal amount of $240 million
under the Acquisition Facility will be paid from the proceeds of the Offerings.
The Credit Facility will remain committed but unused until the Acquisition
Facility is repaid, at which time, the Company will be in compliance with all
financial covenants under the Credit Facility and will again be able to draw
additional funds under such Credit Facility.

                         BUSINESS AND GROWTH STRATEGIES
 
    The Company's primary business objective is to maximize total return to
stockholders through growth in distributable cash flow and appreciation in the
value of its assets. The Company plans to achieve this objective by capitalizing
on the external and internal growth opportunities described below.
 
    Unless indicated otherwise, information contained herein concerning the New
York metropolitan economy and the Manhattan office market is derived from the
Rosen Market Study.
 
THE MARKET OPPORTUNITY
 
    Management believes that current developments in the New York City economy
provide an attractive environment for owning, operating and acquiring Class B
office properties in Manhattan. The New York commercial real estate market is
currently recovering from the sustained downturn of the late 1980s and early
1990s. Specifically, the New York City metropolitan economy has recently
benefited from consistent net private sector job growth, an improving business
environment and enhancements in the "quality of life" afforded to city
residents. In that regard, private sector employment gained an average of more
than 50,300 jobs per year between 1994 and 1997 for an average annual growth
rate of 1.6%; between February of 1997 and 1998, private sector employment
growth was 2.3%, which is the strongest growth rate in more than ten years. Much
of this private sector job growth has been concentrated among smaller companies
involved in growth oriented industries. Smaller companies have traditionally
been attracted to Class B office properties in the Midtown Markets due to their
prime locations and relatively less expensive rental rates (as compared to Class
A office properties). These smaller companies conduct business in industries
including: business services, software, advertising, audio recording, trade
sectors (e.g., apparel and other textile products), major media (e.g.,
television, magazines and publishing), new media (e.g., entertainment software,
online/Internet services, CD-ROM title development and web site design) and
engineering, as well as nonprofit endeavors.
 
    The combination of a growing office space demand fueled by a strengthening
New York City economy and limited recent and projected new supply of office
space has resulted in a recovery in the Midtown Markets. The combined vacancy
rate for Class A and Class B office space in the Midtown Markets declined to
9.1% at March 31, 1998 from a 1990s high of 16.8% at year-end 1991. The Class B
segment of the market tightened to a vacancy rate of 9.8% at March 31, 1998 from
its 1990s high of 17.2% at year-end 1992, a 43.0% decline. According to Rosen
Consulting Group, a nationally recognized real estate consulting company,
between February of 1997 and 1998, private sector employment growth was 2.3%,
which is the strongest growth rate in more than ten years. The outlook in the
New York metropolitan area is for healthy private sector employment growth of
approximately 1.8% per annum in 1998, followed by approximately 1.4% growth per
annum through 2002, which is expected to generate significant demand for office
space. Specifically, Rosen Consulting Group projects vacancy rates in the Class
B Midtown Markets to further drop to 7.0% by 2002, resulting in projected
average asking market rents of $34.14 per square foot, a 23.1% increase over
average asking rents as of March 31, 1998 of $27.74 per square foot. See "Market
Overview." However, conditions in the New York City metropolitan economy and the
Midtown Markets are subject to change and there can be no assurance that any
such projections will approximate actual results. See "Risk Factors--The
Company's Dependence on the Midtown Markets Due to Limited Geographic
Diversification Could Adversely Affect the Company's Financial Performance."
 
    The Company believes the pronounced recovery of Class B space is being
driven by the growth of smaller companies, the relocation of large firms from
Class A space to Class B as a result of the dearth of available Class A space,
particularly in large blocks, and the heightened cost consciousness of large
tenants. In that regard, as of September 1995, there were 30 blocks of 150,000
or more rentable square feet of Class A space available for lease in the Midtown
Markets. As of March 31, 1998 the number of such available blocks had declined
to 15. As the supply of Class A space continues to contract, management believes
that it is likely that more high quality tenants will locate in well-located
Class B office properties, many of which offer comparable amenities to Class A
buildings at a significant discount to Class A costs.
 
    Improving supply and demand fundamentals in the Midtown Markets have
generated increasingly favorable rental terms from a property owner's
perspective. According to Rosen Consulting Group, asking rental rates for Class
B space in the Midtown Markets have increased to $27.74 per square foot as of
 
                                       34
<PAGE>
March 31, 1998 from their 1990s low of $21.90 per square foot as of year-end
1993. See "The Properties-- The Portfolio" for a discussion of Annualized Rent
associated with the Properties.
 
    Management believes that opportunities to acquire Class B office properties
in Manhattan on economically attractive terms will be available to the Company.
The Rosen Consulting Group estimates that the replacement cost of Class A office
space in Manhattan (no Class B space is built in Manhattan) is approximately
$366 per square foot, which is substantially above the estimated current
acquisition price of Class A space of $250 to $325 per square foot and the
estimated current acquisition price for Class B space of $90 to $225 per square
foot. Furthermore, even if rental rates were to approach a level that would
justify new construction, there are few development sites available in Manhattan
and the regulatory approval process is both costly and lengthy. The Company
believes that as the Class A market continues to recover, rental rates and
corresponding property values should increase to a level that may justify new
construction. The Company also believes that property values and rental rates in
the Class B market have historically tracked those of the Class A market and,
consequently, there is potential for rental rate and property value increases in
the Class B marketplace.
 
    Investors should note that the concentration of the Company's investments in
Class B office properties located in Manhattan entails certain risks. See "Risk
Factors--The Company's Dependence on Midtown Markets Due to Limited Geographic
Diversification Could Adversely Affect the Company's Financial Performance" and
"Risk Factors--Competition in its Marketplace Could Have an Adverse Impact on
the Company's Results of Operations."
 
GROWTH STRATEGIES
 
    Management seeks to capitalize on current opportunities in the Class B
Manhattan office market through (i) property acquisitions -- continuing to
acquire Class B office properties at significant discounts to replacement costs
that provide attractive initial yields and the potential for cash flow growth,
(ii) releasing expiring leases to increasing market rates, (iii) property
repositioning -- repositioning acquired properties that are underperforming
through renovations, active management and proactive leasing and (iv) integrated
leasing and property management.
 
PROPERTY ACQUISITIONS
 
    The Company seeks to continue to capitalize on favorable market conditions
for acquiring Manhattan Class B office properties and management's experience in
enhancing the value of its properties. In assessing acquisition candidates, the
Company evaluates the following factors: (i) the property's strategic location
in its marketplace and its strategic fit within the Company's portfolio, (ii)
current and projected occupancy and market rental rates and the ability to
operate the property profitably at competitive rental rates, (iii) the purchase
price as compared to the replacement cost of the property, (iv) the potential to
modify and/or upgrade and reposition the property in its market to increase
returns and (v) the quality of the construction and presence of existing and/or
potential deferred maintenance issues.
 
    The Company believes that it has the following competitive advantages over
its competitors, primarily private companies and individuals, in acquiring Class
B properties in Manhattan:
 
    LOCAL MARKET EXPERTISE.  The Company is a full service, fully integrated
real estate company which manages approximately 10.5 million square feet of
Class B office space in Manhattan. Based upon the eighteen year operating
history of SL Green, management has an extensive working knowledge of the Class
B Manhattan office market with a substantial base of information concerning
current and prospective tenants, effective rental rates, property management and
renovation costs, the complicated regulatory processes characteristic of the
Manhattan office market, as well as other factors relevant to the sourcing and
evaluation of potential acquisition properties. The depth and expertise of the
Company's management is unusual in the Class B marketplace, which has
historically attracted far less institutional interest than the Class A property
sector.
 
    ENHANCED ACCESS TO CAPITAL.  Management believes the Company enjoys better
access to capital than is generally available to private real estate firms,
especially those that compete for Manhattan Class B properties. In that regard,
management believes that ownership of Class B office space in Manhattan is more
fragmented and far less institutional in nature than ownership of Class A
Manhattan office space. As
 
                                       35
<PAGE>
a public company, the Company has the potential to raise capital through
subsequent issuances of securities in the public and private marketplace. The
Company also intends to finance property acquisitions through single asset debt
financings and to obtain revolving credit facilities. However, no assurances can
be made as to the availability of any such financing sources.
 
    UNIT ACQUISITIONS.  As an "UPREIT", the Company has the ability to acquire
properties for Units and thereby provide sellers with deferral of income taxes
that would otherwise be payable upon a cash sale. In addition, Units afford
property sellers diversification and liquidity of investment as well as certain
estate planning benefits. Management believes that the Company operates in an
established and mature real estate market in which many property owners have
owned their properties for many years and therefore have a low tax basis in such
properties. Consequently, the ability to offer Units may afford the Company
certain competitive advantages over other potential acquirors who are unable to
offer tax-efficient consideration.
 
    Investors should note that acquisitions of office properties entail certain
risks. See "Risk Factors-- The Company May Not Achieve Expected Returns on
Recently Acquired Properties and Property Acquisitions."
 
RE-LEASING EXPIRING LEASES TO INCREASING MARKET RENTS
 
    Although there can be no assurances in this regard, the Company believes
that as the commercial real estate market in Manhattan continues to improve,
there will be increasing demand for office space and declining vacancies which
are expected to continue to result in increasing market rents. The Company
believes it has significant opportunities to increase cash flow during such
periods of increasing market rents by renewing or re-leasing expiring leases at
increased market rents. The potential for increasing rental rates is
demonstrated through a comparison of the Direct Weighted Average Office Rental
Rate for the Class B Midtown Markets, according to RELocate, of $27.15 as of
December 31, 1997, as adjusted by the Company to weight the representation of
the Properties in the Midtown Markets to the Annualized Rent Per Leased Square
Foot of Expiring Leases with Future Step-Ups at the Properties and the Pending
Acquisitions of $24.34 for the 502,981 square feet expiring in 1998, $27.16 for
the 368,202 square feet expiring in 1999 and $25.98 for all the Company's leases
as of December 31, 1997. Excluding rental payments attributable to retail space
at the Properties, the Weighted Average Annualized Rent Per Leased Square Foot
of Expiring Leases would be $23.14 for all of the Company's leases as of
December 31, 1997.
 
PROPERTY REPOSITIONING
 
    The Company believes that, consistent with its core operating philosophy of
maximizing asset value, it can reposition future acquisition properties, where
warranted, in order to enhance property cash flow and value. To achieve these
goals, the Company works to increase occupancy and rental rates by repositioning
buildings to be among the best in their submarkets. The Company considers the
amount of capital required to be invested in a property to achieve the
repositioning. The Company then judges the benefit of a repositioning on a total
return basis, such that for the Company to undertake the project the present
value of the projected future increase in net cash flow and property value must
exceed the cost of the capital expenditure required to achieve the
repositioning.
 
    The repositionings pursued by the Company and its predecessors in the past
have consisted of both intensive large scale renovations as well as smaller
scale repositionings. In the case of an intensive large scale renovation, either
a property's use is changed (e.g., from light industrial/warehouse to office) or
a property is completely rehabilitated. In the case of a smaller scale
repositioning, generally cosmetic renovations are made to targeted areas of a
building, deferred maintenance is corrected and an intensive leasing program is
commenced. The Company believes there are a significant number of potential
acquisitions for which this strategy can be successfully implemented due to the
large number of Manhattan office properties that have significant deferred
maintenance or have been undermanaged. The Company believes this situation has
resulted from fragmented ownership that is generally non-institutional and has
limited access to capital.
 
    An important component of the Company's repositioning strategy is its
construction management capability. The construction management division of the
Company and its predecessors has renovated approximately 2.0 million square feet
of office space, including entire building renovations, at an aggregate
 
                                       36
<PAGE>
cost exceeding $100 million. In the past, the Company and its predecessors have
implemented successful repositioning programs which have involved significant
capital investments to improve the physical condition with respect to building
facade, entrance and lobby, mechanical systems (including HVAC, fire/ safety and
elevators) and tenant space layout, while maintaining cost control with respect
to these activities. Additionally, the Company benefits in its repositioning
efforts from its fully-integrated real estate operations. The Company believes
that its in-house leasing, property management and construction management
capabilities provide it with valuable information regarding the cost of
accommodating tenant preferences and the potential rental revenues achievable
from various repositioning options.
 
   
    Examples of successful implementation of this strategy include the Bar
Building (which property accounted for 3.6% of the aggregate Annualized Rent at
the Properties as of December 31, 1997) and 1372 Broadway (which property
accounted for 8.2% of the aggregate annualized Rent at the Properties as of
December 31, 1997). The Company successfully implemented a repositioning
strategy at the Bar Building resulting in NOI increasing from approximately $1.3
million to $2.3 million over the 18 months ending March 31, 1998. When the
Company purchased this Property in October, 1996 it suffered from deferred
maintenance, and was under performing relative to its marketplace as a result of
only a 82% occupancy rate and inefficient building operations. West 44(th)
Street, between Fifth Avenue and Avenue of the Americas, where the Bar Building
is located, has many attractive buildings and prominent clubs which by
association, enhance the value of the Property. Therefore, in order to
capitalize on the location of the building, a modest cosmetic improvement was
implemented, including the restoration of the facade and renovation of common
corridors. As of March 31, 1998 the Property is 100% leased. 43,613 square feet
of vacant space was leased and 61,711 square feet of space was renewed over the
18 months ending March 31, 1998. A similar repositioning strategy was pursued at
1372 Broadway, just 4 blocks south of Times Square. When the Company purchased
this Property in August, 1997 it was only 84% occupied and in immediate need of
a cosmetic renovation in order to take advantage of its superb location and
large floor plates. The Company designed and implemented a $2.0 million lobby
and elevator upgrade program which lead to this Property being 96% leased as of
March 31, 1998. Most importantly, the NOI increased 18% from $4.4 million in
August, 1997 to $5.2 million in March, 1998.
    
 
INTEGRATED LEASING AND PROPERTY MANAGEMENT
 
    The Company seeks to optimize long-term cash flow from its properties
through the implementation and integration of targeted leasing and management
programs.
 
    PROACTIVE LEASING PROGRAM.  The Company seeks to capitalize on its market
position and relationships with an extensive network of brokers and tenants to
implement a proactive leasing program. Management believes that its extensive
knowledge of the Class B Manhattan office market enhances its ability to
monitor, understand and anticipate the current and future space needs of tenants
in its submarkets. The leasing process for an acquisition property begins with
extensive market research in order to determine the strengths and weaknesses of
the property. This review includes an analysis of the building's physical
characteristics, aesthetic attributes, floor plate sizes, services, elevators
and mechanical systems, followed by an in-depth market analysis to determine the
property's competitive position in the marketplace and perception in the
brokerage community. The results of these analyses are used to develop the
appropriate marketing strategy and the appropriate program to communicate the
positive attributes and key features of the property or space to the marketplace
and the brokerage community. These strategies may include the development of
marketing tools such as brochures, listing sheets, fliers, signage and
advertising copy.
 
    The utilization of third-party brokerage firms in implementing a successful
leasing program is an integral component of the Company's leasing strategy. By
closing transactions quickly and at market terms and paying commissions
promptly, the Company and its predecessors have created a network of
relationships with leasing professionals who regularly bring tenants to the
Company's properties.
 
    The Company believes that these proactive leasing efforts have contributed
to average occupancy rates at the Properties that are above the market average.
During the period between 1994 and 1997, the Initial Properties averaged percent
leased rates of 97%, which exceeded the average of 88% for Class B Manhattan
office space in the Midtown Markets by over 10% during the comparable period.
 
                                       37
<PAGE>
    Another key component of the the Company's leasing strategy is a commitment
to tenant retention. Each leasing executive regularly conducts in-person
interviews with existing tenants in order to gain insight into each tenant's
business objectives, financial position and strength and future space
requirements. This knowledge, in addition to a full understanding of each
tenant's current lease obligation, is utilized to develop a plan to retain
existing tenants in order to maximize long term cash flow. The Company's
commitment to tenant service and satisfaction is evidenced by the renewal of
approximately 75% of the expiring rentable square footage (75% of the expiring
leases determined by number of leases) at the Properties in the Core Portfolio
owned and managed by the Company and its predecessors during the period from
January 1, 1994 through December 31, 1997.
 
    IMPLEMENTATION OF STRATEGIC MANAGEMENT SYSTEMS.  The Company's proactive
management begins with a comprehensive operational and physical analysis of a
property followed by a preventive maintenance assessment. SL Green professionals
evaluate all service contracts, survey electrical capacity and costs and, after
interviewing all building personnel, appraise personnel resources and payroll
costs on an ongoing basis. Based on the results of the analysis of the
contractual lease obligations, building position in the market and the
capital/aesthetic improvements needed to bring the property to its desired level
relative to its competition, the Company develops and implements a management
program designed to provide tenants with the highest level of service while
maintaining the lowest cost to ownership.
 
    MAXIMIZING TENANT SATISFACTION.  The Company seeks to provide tenants with a
level of service more typically found in Class A properties. Characteristics of
the Company's office property redevelopments include upgraded or new entrances,
lobbies, elevator cabs/mechanicals, hallways, bathrooms, windows, telecom
systems and tenant spaces. Additionally, the Company seeks to provide certain
tenant amenities typically associated only with Class A properties. For example,
the Company maintains flowers in its buildings' lobbies and also provides
uniformed concierges focused on tenant service as opposed to the security guards
found at many Class B Manhattan office buildings. Within particular submarkets,
the Company arranges for the provision of cleaning and 24 hour, seven days per
week security services to its tenants. The Company believes that this level of
service is unusual in the Class B market, in large part due to the highly
fragmented nature of Class B ownership and management. RELocate, a real estate
market research firm, estimates that the 630 Class B buildings in the Midtown
Markets are owned by over 500 different entities, many of whom own a single
property or a few properties. The Company believes that the relatively large
size of its operations and focus on the Class B market enables it to provide a
level of service superior to that typically provided by the smaller
owner/operators that permeate the Class B Manhattan marketplace.

                                USE OF PROCEEDS
 
    The net cash proceeds to the Company from the PIERS Offering, after
deducting the underwriting discounts and commissions are estimated to be
approximately $96.0 million (approximately $110.4 million if the Underwriters'
over-allotment option is exercised in full). The net cash proceeds to the
Company from the Common Offering, after deducting the underwriting discounts and
commissions are estimated to be $226.8 million (approximately $260.8 million if
the Underwriters' over-allotment option is exercised in full).
 
    The net cash proceeds of the Offerings will be used by the Company as
follows: $240.9 million to repay the Acquisition Facility, (ii) $81.4 million
for the acquisition of the Pending Acquisitions including 1.5 million of
transaction costs (an additional $29.4 million in borrowings from the Credit
Facility and $0.7 million in credits against prior payments under the
Acquisition Facility will be used to acquire the Pending Acquisitions) and (iii)
$1.4 million to pay costs associated with the Offerings. The Acquisition
Facility which closed in March 1998, financed the acquisition of the Helmsley
Properties, paid-off the outstanding balance on the Company's Credit Facility
and provided on-going liquidity for future acquisition and corporate needs. The
term of the Acquisition Facility is one year. The interest rate is determined by
a schedule of the percent of loan commitment outstanding and the applicable
quarterly period extending from March 18, 1998 through the maturity date. The
outstanding principal amount of $240 million under the Acquisition Facility will
be paid from the proceeds from the Offerings. The Credit Facility will remain
committed but unused until the Acquicition Facilty is repaid, at which time the
Company will again be in compliance with all financial covenants under the
Credit Facility and will again be able to draw additional funds under such
Credit Facility.
 
    If the Underwriters' over-allotment options are exercised in full, the
Company expects to use the additional net proceeds (which will be approximately
$14.4 million for the PIERS Offering and $36 million for the Common Offering) to
repay borrowings under the Credit Facility to acquire additional properties
and/or for working capital.
 
    Pending application of the net proceeds of the Offerings, the Company will
invest such portion of the net proceeds in interest-bearing accounts and/or
short-term, interest-bearing securities which are consistent with the Company's
intention to qualify for taxation as a REIT.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
    The Company's ratios of earnings to fixed charges are as follows:

(1) Prior to completion of the IPO on August 20, 1998, the Company's
    predecessors operated in a manner as to minimize net taxable income to the
    owners. The IPO and the related Formation Transactions permitted the Company
    to deleverage its properties significantly, resulting in a significantly
    improved ratio of earnings to fixed charges.
 
    The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges, which includes 100% of majority owned non-combined entities of
the SL Green Predecessor. For this purpose, earnings consist of income (loss)
before gains from sale of property and extraordinary items plus fixed charges.
Fixed charges consist of interest expense (including interest costs
capitalized), the amortization of debt issuance costs and rental expense deemed
to represent interest expense. To date, the Company has not issued any preferred
stock; therefore, the ratios of earnings to fixed charges and preferred stock
dividends are unchanged from the ratios specified above.

(a) On November 5, 1997, the Company's Board of Directors declared a $0.16 per
    share distribution payable November 19, 1997, to stockholders of record on
    November 17, 1997. The distribution was for the period August 20, 1997
    (closing date of the IPO) through September 30, 1997, which is approximately
    equivalent to a full quarterly distribution of $0.35 per share of Common
    Stock and an annual distribution of $1.40 per common share.
 
    Distributions by the Company to the extent of its current and accumulated
earnings and profits for federal income tax purposes, other than capital gain
dividends, will be taxable to stockholders as ordinary dividend income. Capital
gain dividends generally will be treated as long-term capital gain.
Distributions in excess of earnings and profits generally will be treated as a
non-taxable reduction of the stockholder's basis in the Common Stock to the
extent thereof, and thereafter as capital gain. Distributions treated as a non-
taxable reduction in basis will generally have the effect of deferring taxation
until the sale of a stockholder's Common Stock. The Company has determined that
for federal income tax purposes, approximately $0.16 per share (or approximately
100%) of the $0.16 per share distributions paid in 1997 represented ordinary
dividend income to stockholders. No assurances can be given regarding what
percent of future dividends will constitute return of capital for federal income
tax purposes. In order to avoid corporate income taxation of the earnings that
it distributes, the Company must make annual distributions to stockholders of at
least 95% of its REIT taxable income (determined by excluding any net capital
gain), which the Company anticipates will be less than its share of cash
available for distribution. Under certain circumstances, the Company may be
required to make distributions in excess of cash available for distribution in
order to meet such distribution requirements. In such a case, the Company may
find it necessary to arrange for short-term (or possibly long-term) borrowings
or to raise funds through the issuance of preferred shares or additional shares
of Common Stock.
 
    The Company has set a dividend policy whereby regular dividends shall be
payable on the 15th day of the month immediately following the end of each
calendar quarter, or the first business day thereafter, to stockholders of
record on the last day of the quarter. While the Company has established a
policy of paying quarterly distributions, future distributions by the Company
remain at the discretion of the Board of Directors and will depend on the actual
Funds from Operations of the Company, its financial condition, capital
requirements, the annual distribution requirements under the REIT provisions of
the Code (see "Material Federal Income Tax Consequences--Taxation of the
Company"), economic conditions and such other factors as the Board of Directors
deems relevant. See "Risk Factors--Stockholder Approval is Not Required to
Change Policies of the Company" and "Distributions."

1997 and years ended December 31, 1996, 1995, and 1994 of the SL Green
Predecessor have been derived from the historical combined financial statements

operations of the Service Corporations.
 
    The unaudited pro forma consolidated balance sheet of the Company as of

(1) Basic earnings per share excluded any dilutive effect of options
    outstanding. Diluted earnings per share includes the dilutive effect of the
    outstanding options calculated under the treasury stock method. As each Unit
    is redeemable for one share of Common Stock, the calculation of earnings per
    share upon redemption of the outstanding Units will be unaffected, as
    Unitholders and stockholders are entitled to equal distributions on a per
    Unit and per share basis in the net income of the Company. Pro forma basic
    and diluted income before extraordinary item reflect the preferred stock
    dividends and accretion. Pro forma diluted income per share before
    extraordinary item excludes the conversion of the PIERS as the conversion of
    these shares would be antidilutive.
 
(2) The White Paper on Funds from Operations approved by the Board of Governors
    of NAREIT in March 1995 defines Funds from Operations as net income (loss)
    (computed in accordance with GAAP), excluding gains (or losses) from debt
    restructuring and sales of properties, plus real estate related depreciation
    and amortization and after adjustments for unconsolidated partnerships and
    joint ventures. The Company believes that Funds from Operations is helpful
    to investors as a measure of the performance of an equity REIT because,
    along with cash flow from operating activities, financing activities and
    investing activities, it provides investors with an indication of the
    ability of the Company to incur and service debt, to make capital
    expenditures and to fund other cash needs. The Company computes Funds from
    Operations in accordance with standards established by NAREIT which may not
    be comparable to Funds from Operations reported by other REITs that do not
    define the term in accordance with the current NAREIT definition or that
    interpret the current NAREIT definition differently than the Company. Funds
    from Operations does not represent cash generated from operating activities
    in accordance with GAAP and should not be considered as an alternative to
    net income (determined in accordance with GAAP) as an indication of the
    Company's financial performance or to cash flow from operating activities
    (determined in accordance with GAAP) as a measure of the Company's
    liquidity, nor is it indicative of funds available to fund the Company's
    cash needs, including its ability to make cash distributions. For a
    reconciliation of net income and Funds from Operations, see "Management's
    Discussion and Analysis of Financial Condition and Results of
    Operations--Funds from Operations."

in this report that address activities, events or developments that the Company
expects, believes or anticipates will or may occur in the future, including such
matters as future capital expenditures, dividends and acquisitions (including
the amount and nature thereof), expansion and other development trends of the
real estate industry, business strategies, expansion and growth of the Company's
operations and other such matters are forward-looking statements. These
statements are based on certain assumptions and analyses made by the Company in
light of its experience and its perception of historical trends, current
conditions, expected future developments and other factors it believes are

    The following discussion related to the consolidated financial statements of
the Company and the combined financial statements of SL Green Predecessor should
be read in conjunction with the financial statements appearing in Item 8. In
connection with the Formation Transactions as described in Note 1 to the
financial statements there were significant changes in the financial condition
and results of operations of the Company which are outlined below, consequently,
the comparison of the historical periods provides only limited information
regarding the operations of the Company. Therefore, in addition to the
historical comparison, the Company has provided a comparison of the results of
operations on a pro forma basis.
 
RESULTS OF OPERATIONS
 
    COMPARISON OF YEAR ENDED DECEMBER 31, 1997 TO YEAR ENDED DECEMBER 31, 1996
 
    For discussion purposes and to provide comparable periods for analysis, the
following discussion of the results of operations for the year ended December
31, 1997, combines the operating results of SL Green Predecessor for the period
January 1, 1997 to August 20, 1997 and the operating results of the Company for
the period August 21, 1997 to December 31, 1997. Management believes that this
provides for more meaningful analysis of the financial statements to be made.
The results of operations for the year ended December 31, 1996 represent solely
the operating results of the SL Green Predecessor.
 
    Rental revenue and escalation and reimbursement revenue for the year
December 31, 1997 were $27,137,000 representing an increase of 411% compared to
$5,250,000 for the year ended December 31, 1996. The increase is primarily
attributable to (i) the Formation Transactions in which three buildings
accounted for on the equity method are consolidated in the financial statements
of the Company for the period August 21, 1997 to December 31, 1997 and three
buildings (50 West 23rd Street, 1140 Avenue of the Americas and 1372 Broadway)
were acquired, (ii) the inclusion of revenue from 1414 Avenue of the Americas
for the full year during 1997 as compared to six months (purchased in July 1996)
during 1996, and (iii) the results of 110 East 42nd Street (acquired September
15, 1997), 17 Battery Place (acquired December 19, 1997) and 633 Third Avenue
(acquired December 30, 1997) (collectively, the "1997 Acquisitions") are
included in the consolidated financial statements for a portion of the period
August 21, 1997 to December 31, 1997 and not included during any portion of
1996.
 
                                       45
<PAGE>
    Management fee income decreased $1,068,000 for the year ended December 31,
1997 compared to the year ended December 31, 1996 due to (i) lower management
fee revenue being earned in the aggregate $600,000 and (ii) $500,000 in
management fee income which was recorded in the Equity Income (loss) from
Service Corporations for the period August 21, 1997 to December 31, 1997. As of
the IPO date, all third party management income and related expense are incurred
on the books of the Management Corporation, a 95% owned subsidiary of the
Company. This change in the recognition of income and expense from third party
management business activity was made in order to maintain management fee
revenue in a manner which is consistent with the REIT qualifying income test, as
defined by the IRS.
 
    During the reported periods for the Predecessor Company, management revenues
were earned from affiliated properties in which the Predecessor had an interest
and were not eliminated. The amounts related to these properties are:

1996....................    447,000
1995....................    449,000
</TABLE>
 
    Leasing commission revenues increased $1,576,000 for year ended December 31,
1997 compared to the year ended December 31, 1996 due to strong leasing activity
in the current market.
 
    Investment income increased $485,000 for the year ended December 31, 1997
compared to the year ended December 31, 1996 due to interest income earned on
cash on hand. The cash on hand primarily represents excess proceeds from the
IPO.
 
    Other income decreased by $107,000 or 87% to $16,000 during the year ended
December 31, 1997 compared to $123,000 during the year ended December 31, 1996,
primarily due to a one-time consulting engagement in 1996.
 
    Prior to the IPO, third party revenues and income were derived from various
management, leasing and construction activities. As part of the Formation
Transactions, to the extent the Company continues to pursue such business, it
will be conducted through separate subsidiaries. The equity income (loss) from
Service Corporations represents the Company's 95% interest in the net income or
loss derived from these activities. From the period August 21, 1997 to December
31, 1997 the Company recognized $101,000 as its share of the loss by these
subsidiaries.
 
    Operating expenses, depreciation and amortization, and real estate taxes
increased $6,602,000, $2,651,000 and $3,500,000, respectively, as compared to
the year ended December 31, 1996. The increase in these expenses is primarily
attributable to (i) the Formation Transactions in which three buildings (50 West
23rd Street, 1140 Avenue of the Americas and 1372 Broadway) were acquired and
three buildings accounted for on the equity method are consolidated in the
financial statements of the Company for the period August 21, 1997 to December
31, 1997, (ii) the inclusion of expenses from 1414 Avenue of the Americas for
the full year during 1997 as compared to six months (purchased July 1996) during
1996, and (iii) the results of the 1997 Acquisitions included in a portion of
1997 and not included during any portion of 1996.
 
    Interest expense increased $1,840,000 for the year ended December 31, 1997
as compared to the year ended December 31, 1996. The increase is primarily due
to (i) interest expense related to the capitalized lease acquired with a
building previously accounted for under the equity method, (ii) increase of
$21,000,000 in mortgage debt acquired in August 1997 ($14,000,000) and December
1997 ($7,000,000) and (iii) the borrowing of $76,000,000 on December 19, 1997
under the Credit Facility to finance the acquisition of 17 Battery Place.

    COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    Rental revenue increased $1,783,000, or 73.8%, to $4,199,000 from $2,416,000
for the year ended December 31, 1996 compared to the year ended December 31,
1995. The increase was due primarily to the acquisition of 1414 Avenue of the
Americas during July 1996 which had rental revenue of $1,612,000 and increased
occupancy.
 
    Escalations and reimbursement revenues increased $293,000, or 38.6%, to
$1,051,000 from $758,000 for the year ended December 31, 1995. The acquisition
of 1414 Avenue of the Americas accounted for an increase of $428,000 which was
offset by a decrease of $166,000 at 70 West 36th Street due to reduced real
estate tax escalations and porter wage escalation revenue. New leases with more
current base years utilized to calculate the escalations and a reduction in real
estate tax expense accounted for the decreased escalation revenue.
 
    Management revenues remained substantially unchanged with a slight increase
for the year ended December 31, 1996 compared to the year ended December 31,
1995.
 
    Leasing commission revenues increased $1,475,000, or 164.4%, to $2,372,000
from $897,000 for the year ended December 31, 1996 compared to the year ended
December 31, 1995 due to the addition of several buildings under service
contracts and intensified efforts (prior to the IPO) to perform leasing services
for unaffiliated third parties.
 
    Construction revenue decreased by $132,000, or 56.7%, to $101,000 from
$233,000 for the year ended December 31, 1996 compared to the year ended
December 31, 1995. Overall construction revenue remained constant but a larger
amount related to property-owning partnerships and was eliminated pursuant to
the equity method of accounting.
 
    Other income for the year ended December 31, 1996 was $123,000 which
consisted of miscellaneous consulting fees and interest.
 
    Share of net loss of uncombined joint ventures decreased $506,000 or 26.4%
to $1,408,000 from $1,914,000 for the year ended December 31, 1996 compared to
the year ended December 31, 1995 as follows:

</TABLE>
 
    The decrease in net loss for 673 First Avenue was due primarily to lower
interest expense as a result of mortgage loan principal amortization and lower
amortization expense as a result of deferred leasing commissions written off
during 1995 for a tenant that vacated.
 
    The decrease in net loss for 470 Park Avenue South was due primarily to a
reduction in real estate tax expense as a result of a decrease in assessed
valuation.
 
    The decrease in net income for 29 West 35th Street was due primarily to
reduced rental revenue as a result of a vacancy.
 
    The increase in net income for the Bar Building was due to the acquisition
of an interest in the Property during October 1996.

    Operating expenses increased $692,000, or 27.6%, to $3,197,000 from
$2,505,000 for the year ended December 31, 1996 compared to the year ended
December 31, 1995 due substantially to the inclusion of 1414 Avenue of the
Americas which was acquired during July 1996.
 
    Interest expense increased $145,000 or 12.0%, to $1,357,000 from $1,212,000
for the year ended December 31, 1996 compared to the year ended December 31,
1995. The inclusion of 1414 Avenue of the Americas accounted for an increase of
$445,000 which was offset by a decrease of $300,000 for 70 West 36th Street due
to refinancing at a lower interest rate.
 
    Depreciation and amortization increased $200,000, or 25.9%, to $975,000 from
$775,000 for the year ended December 31, 1996 compared to the year ended
December 31, 1995. The increase was due primarily to the inclusion of 1414
Avenue of the Americas.
 
    Real estate taxes increased $207,000 or 41.7%, to $703,000 from $496,000 for
the year ended December 31, 1996 compared to year ended December 31, 1995. The
increase was due to the inclusion of $290,000 for 1414 Avenue of the Americas
offset by a decrease of $83,000 for 70 West 36th Street which resulted from a
reduction in property assessment.
 
    Marketing, general and administrative expenses increased $198,000, or 6.5%,
to $3,250,000 from $3,052,000 for the year ended December 31, 1996 compared to
the year ended December 31, 1995, due primarily to staff increases for the
corporation which provided leasing services.
 
    As a result of the foregoing, the loss before extraordinary item decreased
$2,682,000, or 79.1%, to $708,000 from $3,390,000 for the year ended December
31, 1996 compared to the year ended December 31, 1995.
 
PRO FORMA RESULTS OF OPERATIONS
 
    YEAR ENDED DECEMBER 31, 1997
 
   
    On a pro forma basis after giving effect to the Offerings, the IPO, the
Formation Transactions and the purchase of the IPO Acquisition Properties, the
Acquired Properties and the Pending Acquisitions, income before minority
interest and extraordinary item would have been $36,394,000 for the year ended
December 31, 1997, representing an increase of $28,296,000 over the historical
income before minority interest for the comparable year. The historical income
before minority interest represents the consolidated historical results of the
Company for the period August 21, 1997 to December 31, 1997 and the combined
historical results of SL Green Predecessor for the period January 1, 1997 to
August 20, 1997. The increase is accounted for as follows:

LIQUIDITY AND CAPITAL RESOURCES
 
    The SL Green Predecessor historically relied on mortgage financing plus the
use of its capital for the acquisition, redevelopment and renovation of
properties. The proceeds from the IPO as well as a new mortgage loan in the
amount of $14 million, which is secured by 50 West 23rd Street, were utilized to
repay existing mortgage loans, acquire properties, pay IPO and Formation
Transaction expenses and provide working capital. Total mortgage loans including
the new mortgage loan amounted to $45.8 million as a result of the Formation
Transactions. All mortgage loans encumbering the Properties at the time of the
IPO closing had fixed interest rates ranging from 7.47% to 9.0%.
 
    On December 19, 1997 the Company entered into the $140 million Credit
Facility due December 2000. Availability under the Credit Facility may be
limited to an amount less than $140 million. Availability is calculated by
reference to several factors including recent acquisition activity and most
recent quarterly property performance. Outstanding loans under the Credit
Facility bear interest at a rate per annum equal to LIBOR applicable to each
interest period plus 130 basis points to 145 basis points per annum. The Credit
Facility requires the Company to comply with certain covenants, including but
not limited to, maintenance of certain financial ratios. At December 31, 1997
the outstanding amount of indebtedness under the Credit Facility was $76
million, and the interest rate on such indebtedness was 7.265% per annum.
 
    On December 30, 1997 the Company entered into a $7 million additional
advance under its existing mortgage loan which is secured by 50 West 23rd
Street. The note bears interest at a rate of LIBOR plus 175 basis points
(7.6875% at December 31, 1997). On April 3, 1998, this mortgage note was fixed
at 7.06%, maturing co-terminous with the underlying mortgage note. As of April
15, 1998 the current amount of the mortgage note was $21 million.
 
    On March 18, 1998, the Company asked the Credit Facility banking group to
temporarily relieve the Company from its obligations under the financial
covenants of the Credit Facility, in order to close the Acquisition Facility.
The Acquisition Facility, which closed in March 1998, financed the purchase of
the Helmsley Properties acquisition, paid off the outstanding balance on the
Credit Facility and provided ongoing liquidity for future acquisition and
corporate needs. The term of this facility is one year. The interest rate is
determined by a schedule of the principal balance of the loan outstanding and
the applicable quarterly period extending from March 18, 1998 through the
maturity date. The outstanding principal amount of $240 million under the
Acquisition Facility will be paid from the proceeds of the Offerings. The Credit
Facility will remain committed but unused until the Acquisition Facility is
repaid at which time, the Company will be in compliance with all financial
covenants under the Credit Facility and will again be able to draw additional
funds under such Credit Facility.
 
    The Company estimates that for the 12 months ending December 31, 1998 and
1999, it will incur approximately $6.6 million and $3.2 million, respectively,
of capital expenditures on Properties owned at December 31, 1997. In 1998, over
$5.8 million of the capital investments are dedicated to redevelopment costs
associated with properties purchased at or after the Company's IPO. The Company
expects to fund these capital expenditures with the Acquisition Facility, Credit
Facility, operating cash flow and cash on hand. Future property acquisitions may
require substantial capital investments in such properties for refurbishment and
leasing costs. The Company expects that these financing requirements will be
provided primarily from its existing Credit Facility, from additional borrowings
secured by one or more properties and from future issuances of equity and debt.
The Company believes that it will have sufficient capital resources to satisfy
its obligations during the next 12 month period. Thereafter, the Company expects
that capital needs will be met through a combination of net cash provided by
operations, borrowings and additional equity issuances.
 
    The Company expects to continue making distributions to its stockholders
primarily based on its distributions received from the Operating Partnership or,
if necessary, from working capital or borrowings.
 
                                       50

The Operating Partnership income will be derived primarily from lease revenue
from the Properties and, to a limited extent, from fees generated by the Service
Corporations.
 
CASH FLOWS
 
    COMPARISON OF THE YEAR ENDED DECEMBER 31, 1997 TO YEAR ENDED DECEMBER 31,
     1996
 
    Net cash provided by operating activities increased $8,279,000 during the
year ended December 31, 1997 to $8,551,000 from $272,000 for the year ended
December 31, 1996. The increase was due primarily to the inclusion of properties
encompassed in the Offering and Formation Transaction (the acquisition of 50
West 23rd Street, 1140 Avenue of the Americas and 1372 Broadway) as of August
21, 1997, the acquisition of 1414 Avenue of the Americas (acquired July 1996),
110 East 42nd Street (acquired September 1997) and 17 Battery Place (acquired
December 1997) and an increase in leasing commission and investment income. Net
cash used in investing activity increased $210,349,000 during the year ended
December 31, 1997 to $222,724,000 as compared to $12,375,000 for the year ended
December 31, 1996. The increase is primarily due to the acquisition of certain
properties at the date of the IPO, the purchase of 110 East 42nd Street in
September 1997 and the purchase of an interest in 17 Battery Place and 633 Third
Avenue in December 1997. Net cash provided by financing activities increased by
$215,056,000 during the year ended December 31, 1997 to $227,016,000 as compared
to $11,960,000 during the year ended December 31, 1996. The primary reason for
the increase is (i) net proceeds from the IPO, (ii) net proceeds from mortgage
notes payable and (iii) proceeds from the Credit Facility. These proceeds were
used to purchase the properties described above.
 
    COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    Net cash provided by operating activities increased $506,000 to $272,000
from a deficit of $234,000 for the year ended December 31, 1996 compared to the
year ended December 31, 1995. The increase was due primarily to the acquisition
of 1414 Avenue of the Americas, an increase in leasing commission income. Net
cash used in investing activities increased $11,943,000 to $12,375,000 from
$432,000 for the year ended December 31, 1996 compared to the year ended
December 31, 1995. The increase was due primarily to the acquisition of 1414
Avenue of the Americas plus contributions to the partnerships that own 470 Park
Avenue South and the Bar Building. Net cash provided by financing activities
increased $11,897,000 to $11,960,000 from $63,000 for the year ended December
31, 1996 compared to the year ended December 31, 1995. The increase was due
primarily to the financing of the acquisition of 1414 Avenue of the Americas,
the refinancing of the mortgage on 70 West 36th Street and net cash contribution
from owners.
 
FUNDS FROM OPERATIONS
 
    The White Paper on Funds from Operations approved by the Board of Governors
of NAREIT in March 1995 defines Funds from Operations as net income (loss)
(computed in accordance with GAAP), excluding gains (or losses) from debt
restructuring and sales of properties, plus real estate related depreciation and
amortization and after adjustments for unconsolidated partnerships and joint
ventures. The Company believes that Funds from Operations is helpful to
investors as a measure of the performance of an equity REIT because, along with
cash flow from operating activities, financing activities and investing
activities, it provides investors with an indication of the ability of the
Company to incur and service debt, to make capital expenditures and to fund
other cash needs. The Company computes Funds from Operations in accordance with
standards established by NAREIT which may not be comparable to Funds from
Operations reported by other REITs that do not define the term in accordance
with the current NAREIT definition or that interpret the current NAREIT
definition differently than the Company. Funds from Operations does not
represent cash generated from operating activities in accordance with GAAP and
should not be considered as an alternative to net income (determined in
accordance with GAAP) as an indication of the Company's financial performance or
to cash flow from operating activities (determined in
 
                                       51
<PAGE>
accordance with GAAP) as a measure of the Company's liquidity, nor is it
indicative of funds available to fund the Company's cash needs, including its
ability to make cash distributions.
 
    On a pro forma basis after giving effect to the IPO, Funds from Operations
for the year ended December 31, 1997 is as follows:

INFLATION
 
    Substantially all of the office leases provide for separate real estate tax
and operating expense escalations over a base amount. In addition, many of the
leases provide for fixed base rent increases or indexed escalations. The Company
believes that inflationary increases may be at least partially offset by the
contractual rent increases described above.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    Financial Accounting Standards Board Statement No. 131 ("FAS No. 131")
"Disclosure about Segments of an Enterprise and Related Information" is
effective for financial statements issued for periods beginning after December
15, 1997. FAS No. 131 requires disclosures about segments of an enterprise and
related information regarding the different types of business activities in
which an enterprise engages and the different economic environments in which it
operates.
 
    The Company does not believe that the implementation of or FAS No. 131 will
have a significant effect on its financial statements.
 
YEAR 2000 COMPLIANCE
 
    The Company has determined that it will need to modify or replace
significant portions of its software so that its computer systems will function
properly with respect to dates in the year 2000 and beyond. The Company's
comprehensive Year 2000 initiative is being managed by a team of internal staff
and outside consultants. The team's activities are designed to ensure that there
is no adverse effect on the Company's core business operations and that
transactions with customers, suppliers, and financial institutions are fully
supported. The Company is well under way with these efforts, which are scheduled
to be completed in mid-1998. While the Company believes its planning efforts are
adequate to address its Year 2000 concerns, there can be no guarantee that the
systems of other companies on which the Company's systems and operations rely
will be converted on a timely basis and will not have a material effect on the
Company. The cost of the Year 2000 initiatives is not expected to be material to
the Company's results of operation or financial position.

                                MARKET OVERVIEW
 
    UNLESS INDICATED OTHERWISE, INFORMATION CONTAINED HEREIN CONCERNING THE NEW
YORK METROPOLITAN ECONOMY AND THE MANHATTAN OFFICE MARKET IS DERIVED FROM THE
ROSEN MARKET STUDY.
 
    The Company believes that the strength of the New York metropolitan economy
and the current supply/demand fundamentals in the Manhattan office market
provide an attractive environment for acquiring, owning and operating Class B
office properties.
 
NEW YORK ECONOMY
 
    New York City is a leading international city with a large, dynamic and
diverse economy. According to the U.S. Bureau of Economic Analysis, as of July
1995, the economy of the New York consolidated metropolitan statistical area
("CMSA") was larger than the economies of the next two largest U.S. CMSAs
combined (Los Angeles and Chicago), and larger than the economy of any
individual state except California, based on aggregate personal income (which
the Company believes is a good proxy for overall economic output). Strong growth
of the national economy has benefited New York City, causing the New York
metropolitan area (including Bronx, Kings, New York, Putnam, Queens, Richmond,
Rockland and Westchester counties) economy to improve significantly in recent
years. Private sector employment gained an average of approximately 50,300 jobs
per year between 1994 and 1997 for an average annual growth rate of 1.6%;
between February of 1997 and 1998, private sector employment growth was an even
stronger 2.3%, which is the strongest growth rate in more than ten years. In
November of 1997, Fortune Magazine ranked New York as the most improved city for
business. Also in 1997, Inc. Magazine recognized New York as the city with the
largest number of growing, privately-held companies.
 
    With its unique appeal, New York City is headquarters to many of the leading
corporations and service firms in the U.S., including:
 
    - more Fortune 500 companies (46) than any other U.S. city;
 
    - three of the four largest U.S. commercial banks (400 international banks
      have offices in New York City--more than any other city in the world);
 
    - 23 of the 25 largest U.S. securities firms;
 
    - four of the 10 largest U.S. money managers;
 
    - 27 of the 100 largest U.S. law firms (64 of the 100 largest U.S. law firms
      have offices in New York City);
 
    - four of the "Big Six" accounting firms; and
 
    - four of the largest U.S. entertainment/media conglomerates.
 
    New York is also a world leader in the advertising industry and contains a
large base of nonprofit organizations. It also has the largest consulate
community in the world, contributing to its position as an international center
of business and politics.
 
    In addition to its diverse base of large businesses, Manhattan also has a
large base of small companies. The New York City Office of the Comptroller
reports that small businesses (which are defined as businesses with fewer than
500 employees) comprise approximately 99.7% of all businesses in New York City
and employ approximately 70.7% of the private-sector work force. In the four
years between 1994 and 1997, during which period some 201,200 private sector
jobs were added in the New York metropolitan area (an average of approximately
50,300 each year), the percentage of jobs added from small business has grown
increasingly more significant, especially in New York City, where small
businesses added approximately 69,000 jobs during 1994 and 1995 and
approximately 42,000 jobs between the fourth quarters of 1996 and 1997.
 
                                       53
<PAGE>
    The single fastest-growing employment sector in the New York metropolitan
economy is the services sector, which grew at a rate of 3.5% during the year
ended in February of 1998. With almost 1.5 million jobs, the services sector
currently represents 38% of the New York metropolitan area's total employment
base and 44% of its private sector employment base. Important components of the
services sector are business services, legal services, engineering and
management services and membership organizations (including approximately 20,000
nonprofit organizations which are based in New York City). One of the largest
components of the services industry is business services, which supplied
approximately 307,000 jobs as of February 1998, representing 21% of total
services employment. Between 1992 and 1997, growth in business services
employment averaged 4.9% per year, and between February 1997 and February 1998,
business services employment grew 7.3%. Fueling the growth in the business
services sector are the advertising industry, audio recording, software
industries and agencies providing temporary workers. One very active sector of
business services is the new media industry that is centered south of 41st
Street in what is known as midtown south's "Silicon Alley." The companies that
work in this industry include entertainment software, online/Internet services,
CD-ROM title developers, and web site designers. According to the State Deputy
Comptroller for New York City, New Media employment has nearly doubled in size
to just over 30,000 jobs between 1993 and 1997.
 
    The trade sector is the second largest and fastest growing part of the
metropolitan economy, with an employment gain of 13,800 jobs during the 12
months ended February 28, 1998, representing a 2.1% annual growth rate.
Approximately 68% of the metropolitan area's trade jobs are in the retail
sector, where growth was an even stronger 2.4% during the same period. The
retail industry has benefited from improved city services, reduced crime and an
increase in the number of visitors and their spending volume.
 
    Part of New York City's appeal to employers is a highly educated work-force.
Over 40% of New York County's residents over the age of 25 have received a
college degree and nearly half of those residents have received a graduate or
professional degree, rates that are well above the national average. In
addition, with a population of approximately 7.4 million, including
approximately 96,300 households that have an annual effective buying/disposable
income in excess of $150,000, New York City also provides a large base of
potential consumers with significant disposable income, which is of particular
appeal to businesses providing goods and services. Increased spending by local
residents combined with a higher level of visitor spending caused retail sales
growth in New York City to average 3.2% annually during the period January 1,
1994 to December 31, 1996.
 
    New York City is an international financial and cultural capital that, in
addition to housing the United Nations and numerous foreign missions, attracts
tourism, is a center for international investment and a favored North American
base for many multinational corporations headquartered overseas. The lower cost
of office rents when compared internationally with other major cities is a
competitive advantage in attracting such overseas companies to New York City.
Midtown Manhattan ranks 13th among major business centers around the world in
terms of office occupancy costs, after such cities as Tokyo, London, Paris, Hong
Kong and Singapore, while downtown Manhattan ranked 31st.
 
    New York City is the consummate "24-hour city," featuring a wide variety of
restaurants, entertainment and cultural offerings, such as Broadway theater and
productions at Carnegie Hall and Lincoln Center. In addition, many of the
world's finest museums, including The Metropolitan Museum of Art, The Museum of
Modern Art, The Guggenheim Museum, The Whitney Museum and The Museum of Natural
History, are located in New York City. New York City is also home to major
educational institutions, including Columbia University, Fordham University, New
York University and Rockefeller University.
 
    The quality of life in New York City also has improved with the
implementation of various public/ private ventures and government initiatives.
For example, Business Improvement Districts ("BIDs"), which are public/private
ventures that provide security, sanitation and other services within their
boundaries, operate in the Grand Central Station, Penn Station and Times Square
areas and in 36 additional areas within New York City. In addition, crime in New
York City has declined. The Rosen Consulting Group
 
                                       54
<PAGE>
estimates show that New York City ranked 151st out of the 182 largest U.S.
cities in terms of total crimes per capita for the first half of 1997, lower
than such cities as Las Vegas (1), Atlanta (3), Miami (5), Phoenix (40), and
Milwaukee (84). According to the New York City Police Department, New York
City's crime rate decreased 44% between 1993 and 1997, including a 9% drop
during 1997 (a greater decrease than any other large U.S. city during the last
four years).
 
    The New York City government is "reinventing" itself in an effort to
streamline its operations and attract and retain businesses. For example, the
New York Economic Development Council has been actively involved in encouraging
businesses to remain in New York City. New York City also has recently reduced
or eliminated numerous taxes, including the real property transfer tax, the
unincorporated businesses tax, the commercial rent tax, the hotel occupancy tax
and the sidewalk vault tax. New York City also was influential in eliminating
the New York State real property gains tax. Even with the reduction or
elimination of numerous taxes, New York City has announced a budget surplus for
its fiscal year ended June 30, 1997 of approximately $856 million, as a result
of savings in operating expenses and improvements in the New York City economy.
 
    With its dynamic and diverse base of businesses, New York City is poised to
continue its course of steady growth and economic improvement. Private sector
job creation in the New York metropolitan area is anticipated to continue at an
average rate of 1.8% during 1998, for the addition of approximately 60,000
private sector jobs, and continue to increase at approximately 1.4% annually
through 2002.
 
MANHATTAN OFFICE MARKET
 
    OVERVIEW.  The Company believes that current supply/demand fundamentals in
the Manhattan office market provide an attractive environment for acquiring,
owning and operating Class B Manhattan office properties. Specifically, the
Midtown Markets have the following favorable characteristics: (i) the Class A
and Class B sectors of the Midtown Markets, collectively, have experienced five
consecutive years of positive net absorption and declining vacancy rates; (ii)
there have been virtually no new additions to supply in the Midtown Markets
since 1993; and (iii) new office development is limited at the current time
because there are relatively few sites available for construction, the lead time
required for construction typically exceeds three years and new construction
generally is not economically feasible given current market rental rates.
 
    The Manhattan office market consists primarily of midtown, midtown south and
downtown submarkets. According to Rosen Consulting Group, midtown extends from
the north side of 32nd Street to 62nd Street; midtown south is defined as Canal
Street to the south side of 32nd Street; and downtown is defined as Battery to
Canal Street. In each case the submarkets are defined from the East River on the
east to the Hudson River on the west. As referred to herein, the Midtown Markets
collectively consist of midtown and midtown south.
 
                                       55
<PAGE>
    SIZE OF MARKET.  The Manhattan office market, with an overall stock of
almost 380 million square feet, is the largest office market in the U.S and is
larger than the next six largest U.S. central business district office markets
combined (Chicago, Washington, D.C., Boston, San Francisco, Philadelphia and Los
Angeles). The following chart sets forth the size of the Manhattan office market
and the size of certain other U.S. office markets, as of December 31, 1997:

    HISTORICAL PERSPECTIVE.  The Midtown Markets experienced rapid growth both
in demand for, and supply of, office space during the 1980s. A wave of new
construction peaked in the late 1980s and, between 1985 and 1992, 39 buildings
containing approximately 20.3 million square feet of space were built. However,
since 1992, there has been very little new construction in the Midtown Markets.

                 [Bar chart showing new construction from 1980
                        through the projection for 1998]

                                 (projections).
 
    In the late 1980s and early 1990s, as much of the new supply of office space
was being delivered, the demand for space in the Midtown Markets fell off
abruptly as a result of the general downturn in the economy and subsequent
corporate downsizings. As a result of the increase in inventory and the
significant decrease in employment in Manhattan, Class A vacancy rates in the
Midtown Markets increased into the double digits, reaching 17.8% in 1991 and
Class B vacancy rates in the Midtown Markets increased to 17.2% in 1992.
 
    In the early 1990s, however, conditions began to improve in the Midtown
Markets, as a result of the following factors: new jobs were created as the
national and New York metropolitan economies recovered from their downturns;
existing midtown Manhattan businesses expanded, resulting in an increased need
for office space.
 
    LIMITED SUPPLY OF NEW OFFICE SPACE.  The Company expects the supply of
office space in the Midtown Markets to remain relatively stable through the year
2000 because there are relatively few sites available for construction, the lead
time required for construction typically exceeds three years and new
construction generally is not economically feasible at current market rental
rates. Only one major Class A development, containing approximately 1.5 million
square feet, which has substantial grandfathered tax benefits, is scheduled to
be completed in 1999. (The Company does not believe that this property will have
a material impact on the market because it represents less than 1% of the total
Class A midtown office space and is already substantially preleased to two
tenants.) Four other development sites were purchased recently which could
accommodate a total of 3.7 million square feet of office space, although
construction is not yet underway on any of these projects. In the absence of tax
incentives, the Company believes that rents generally would have to increase
significantly to justify the cost of new construction. Assuming development
costs of approximately $366 per square foot (as estimated by Rosen Consulting
Group), a market
 
                                       57
<PAGE>
base rent of approximately $56 per square foot would be needed to make
construction economically viable. This suggests that, in order to justify new
construction, market base rents (not taking into account any tax benefits that
may apply) generally would have to increase to at least 30% more than current
asking rents for Class A office space in midtown Manhattan (as estimated by
Rosen Consulting Group).
 
    INCREASING DEMAND FOR OFFICE SPACE IN THE MIDTOWN MARKETS.  In addition, net
absorption as calculated by Rosen Consulting Group ("Net Absorption") of Class B
office space in the Midtown Markets has been positive since 1992 and surged in
1994, 1995, 1996, and 1997 reaching 3.0 million, 1.6 million, 1.7 million and
1.8 million square feet, respectively. An average of 28,200 office
space-consuming jobs are projected to be created annually from 1998 until 2002.
 
                     NET ABSORPTION OF CLASS B OFFICE SPACE
 
                                MIDTOWN MARKETS
 
           [Bar chart showing net absorption of Class B office space
                            from 1993 through 2002]
 
    As a result of sustained positive Net Absorption coupled with virtually no
new construction since 1992, the Class A office vacancy rate in the Midtown
Markets had fallen to 8.5% as of March 31, 1998 from its 1990s high of 17.8% in
1991 and the Class B office vacancy rate in the Midtown Markets had fallen to
9.8% from its 1990s high of 17.2% in 1992. As a result of the projected economic
strength and private sector job growth, combined with limited projected new
construction through 2000, Rosen Consulting Group projects that the Class A
vacancy rate in the Midtown Markets will fall to 6.5% in 1998 and further to
5.8% in 2002; similarly, Rosen Consulting Group projects that the Class B
vacancy rate in the Midtown Markets will fall to 9.1% in 1998 and further to
7.0% in 2002. The Company believes the demand for Class B space will increase as
a result of the expectation of the following factors: (i) growth in the office
space demands of small businesses, which generally choose to locate in office
space with lower occupancy costs, (ii) the continued desire of larger
corporations to reduce office occupancy costs and (iii) growth in key office-
consuming sectors such as finance, securities, legal services and accounting
which would reduce the availability of Class A office space.
 
    The following chart shows the history and projections of vacancy rates and
asking rents for Class B office space in the Midtown Markets. According to Rosen
Consulting Group, rent growth is inversely related to vacancy rates. When market
conditions tighten and the market vacancy rate falls below the optimal vacancy
rate, rent growth accelerates. The optimal vacancy rate is the vacancy rate at
which neither
 
                                       58
<PAGE>
excess supply nor excess demand exists, and it is determined by examining the
historical relationship between vacancy rates and rent growth. As shown in the
chart below, the Class B vacancy rate in the Midtown Markets rose to its highest
level in 1992, at which time average asking rents continued to decline to their
lowest levels in 1993. Since 1992, the Class B vacancy rate has decreased, and
as the actual vacancy rate has approached the optimal vacancy rate, average
asking rents stabilized and began to rise in 1995.
 
    The chart further shows that as vacancy rates decline below the optimal rate
of 10% (as is projected to occur over the next four years), projected asking
rents begin to increase at an accelerated rate over current levels. In light of
the supply and demand fundamentals outlined above and the estimate of Class A
base rental rates required to justify new office construction (of approximately
$56 per square foot), the Company believes the estimate in the chart below of
Class B asking rents in the $30 per square foot range at a projected vacancy
level of 8% to be reasonable. However, conditions in the Midtown Markets are
subject to change and there can be no assurance that any projections will
approximate actual results. See "Risk Factors--The Company's Dependence on the
Midtown Markets Due to Limited Geographic Diversification Could Adversely Affect
the Company's Financial Performance."

                        through the projection for 2002]
 
    POSITIVE OUTLOOK FOR EFFECTIVE RENTAL RATES.  As discussed above, the
Company anticipates continued growth in the demand for Class A and Class B
office space in the Midtown Markets and relatively little new supply of such
space being delivered over the next several years. Accordingly, the Company
believes that vacancy rates among Class A and Class B properties in the Midtown
Markets should continue to
 
                                       59
<PAGE>
decrease, which the Company believes should result in increased rental rates and
decreased re-leasing costs in well-managed, well-located Class A and Class B
office properties. However, there can be no assurance that any of these
expectations will be met.
 
    DOWNTOWN SUBMARKET. The downtown submarket of the Manhattan office market,
where the Option Property is located, has been the subject of significant
revitalization efforts in recent years. The Downtown Commercial Revitalization
Program offers a mix of commercial rent tax, real estate tax and energy expense
relief to tenants who sign new or renew leases in buildings constructed before
1975. These efforts appear to be yielding results, as the vacancy rate for
downtown Class B office space had declined to 18.2% as of March 31, 1998 from
its 1990s high of 21.3% at the end of 1995 (although such rate represents an
increase from the vacancy rate of 17.8% at the end of 1996). In addition,
average asking rents per square foot for Class B office space in the downtown
submarket rose to $24.12 as of March 31, 1998 from its 1990s low of $21.53 at
the end of 1995. Rosen Consulting Group projects the vacancy rate for downtown
Class B office space to decrease to 17.2% by the end of 1998 and to continue to
decline to 14% by 2002. In addition, Rosen Consulting Group estimates that
average asking rents per square foot for Class B office space in the downtown
submarket will increase to $24.17 by the end of 1998 and continue rising to
$27.47 by the end of 2002.

                                 THE PROPERTIES
 
THE PORTFOLIO
 
    GENERAL.  The Company owns or has contracted to acquire interests in 19
Class B office properties located primarily in Manhattan which contain
approximately 6.1 million rentable square feet (one property is located in
downtown Manhattan and one property is located in Brooklyn). Certain of the
Properties include at least a small amount of retail space on the lower floors,
as well as basement/storage space. One Property (673 First Avenue) and one
Pending Acquisition (711 Third Avenue) include underground parking. The Company
believes that each of the Properties is adequately covered by property and
liability insurance.
 
    As noted above under "Market Overview," the Manhattan office market is
predominantly segregated into two distinct categories: Class A and Class B. The
Class B category generally includes office properties that are more than 25
years old, in good physical condition, attract high-quality tenants and are
situated in desirable locations in Manhattan. Class B properties can be
distinguished from Class A properties in that Class A properties are generally
newer properties with higher finishes and obtain the highest rental rates in
their markets.
 
    The following table sets forth certain information with respect to each of
the Properties and the Pending Acquisitions as of December 31, 1997:

(1) As used throughout this Prospectus, Annualized Rent represents the monthly
    contractual rent under existing leases as of December 31, 1997 multiplied by
    12. This amount reflects total rent before any rent abatements and includes
    expense reimbursements, which may be estimated as of such date. Total rent
    abatements for leases in effect as of December 31, 1997 for the 12 months
    ending December 31, 1998 are approximately $888,000.
    
 
(2) Annualized Rent Per Leased Square Foot, as used throughout this Prospectus,
    represents Annualized Rent, as described in footnote (1) above, presented on
    a per leased square foot basis.
 
                                       61
<PAGE>
(3) As used throughout this Prospectus, Annual Net Effective Rent Per Leased
    Square Foot represents (a) for leases in effect at the time an interest in
    the relevant property was first acquired by the Company or its predecessors,
    the remaining lease payments under the lease including escalations
    (excluding operating expense pass-throughs, if any) divided by the number of
    months remaining under the lease multiplied by 12 and (b) for leases entered
    into after an interest in the relevant property was first acquired by the
    Company or its predecessors and for leases at the Acquired Properties, all
    lease payments under the lease including escalations (excluding operating
    expense pass-throughs, if any) divided by the number of months in the lease
    multiplied by 12, and, in the case of both (a) and (b), minus tenant
    improvement costs and leasing commissions, if any, paid or payable by the
    Company or its predecessors and presented on a per leased square foot basis.
    Annual Net Effective Rent Per Leased Square Foot includes future contractual
    increases in rental payments and therefore, in certain cases, may exceed
    Annualized Rent Per Leased Square Foot.
 
(4) The Company holds a long-term leasehold interest in the land and
    improvements with respect to this Property. See "--673 First Avenue," "-- 36
    West 44th Street (The Bar Building)" and "--1140 Avenue of the Americas."
 
(5) 470 Park Avenue South is comprised of two buildings, 468 Park Avenue South
    (a 17-story office building) and 470 Park Avenue South (a 12-story office
    building).
 
(6) The Bar Building is comprised of two buildings, 36 West 44th Street (a
    14-story building) and 35 West 43rd Street (a four-story building).
 
(7) The Company has a co-tenancy interest in this Property. See "--17 Battery
    Place."
 
(8) The Company holds fee interests in condominium units comprising
    approximately 41,000 square feet of this one million square foot office
    building. The units are currently leased to primarily retail tenants. See
    "--633 Third Avenue (partial interest)."
 
(9) The Company holds an operating sublease interest in the land and
    improvements with respect to this Property. See "--420 Lexington Avenue (The
    Graybar Building)."
 
(10) The Company will hold a leasehold mortgage interest, a net sub-leasehold
    interest and a co-tenancy interest in this property. See "The
    Properties--Pending Acquisitions--711 Third Avenue."
 
(11) Does not count the 45,000 square foot garage as a lease or as part of the
    property's rentable square feet. The garage is operated by a third party
    pursuant to a management contract. If the garage were counted as leased, the
    percent leased at this Pending Acquisition would have been 8.1%.
 
(12) Does not include rent from the 45,000 square foot garage at this property.
 
(13) Includes approximately 5,602,600 square feet of rentable office space,
    348,700 square feet of rentable retail space 29,700 square feet of mezzanine
    space and 75,000 square feet of garage space.

    LEASE EXPIRATIONS.  Leases at the Properties, as at many other Manhattan
office properties, typically extend for a term of ten or more years, compared to
typical lease terms of 5-10 years in other large U.S. office markets. From
January 1, 1994 through December 31, 1997, the Company or its predecessor
renewed approximately 75% of the leases scheduled to expire at the Properties
owned and managed by the Company or its predecessor during such period,
constituting renewal of approximately 75% of the expiring rentable square
footage during such period. Through December 31, 2002, the average annual
rollover at the Properties and the Pending Acquisitions is approximately 503,205
square feet, representing an average annual expiration of 9.5% of the total
leased square feet at the Properties and the Pending Acquisitions per year
(assuming no tenants exercise renewal or cancellation options and no tenant
bankruptcies or other tenant defaults).

- ------------------------
 
   
(1) Annualized Rent of Expiring Leases, as used throughout this Prospectus,
    represents the monthly contractual rent under existing leases as of December
    31, 1997 multiplied by 12. This amount reflects total rent before any rent
    abatements and includes expense reimbursements, which may be estimated as of
    such date. Total rent abatements for leases in effect as of December 31,
    1997 for the 12 months ending December 31, 1998 are approximately $888,000.
    
 
(2) Annualized Rent Per Leased Square Foot of Expiring Leases, as used
    throughout this Prospectus, represents Annualized Rent of Expiring Leases,
    as described in footnote (1) above, presented on a per leased square foot
    basis.
 
(3) Annualized Rent Per Leased Square Foot of Expiring Leases With Future
    Step-Ups represents Annualized Rent Per Leased Square Foot of Expiring
    Leases, as described in footnote (2) above, adjusted to reflect contractual
    increases in monthly base rent that occur after December 31, 1997.
 
(4) For comparison purposes, the Direct Weighted Average Rental Rate for the
    Class B Midtown Markets, according to RELocate (as adjusted by the Company
    to weight the representation of the Properties in the Chelsea, Grand Central
    North, Grand Central South, Garment, Park Avenue South/Flatiron, Rockefeller
    Center and Times Square submarkets), was $27.15 per square foot as of
    December 31, 1997. The Direct Weighted Average Rental Rate represents the
    weighted average of asking rental rates for direct Class B office space as
    it relates to the Properties, except for 17 Battery Place which is located
    in the World Trade/Battery submarket of the downtown Manhattan office
    market. Asking rental rates generally are higher than actual rental rates
    (which generally are not publicly available). In addition, the Direct
    Weighted Average Rental Rate represents a large number of Class B properties
    in various locations within the Midtown Markets, and, therefore, may not be
    representative of asking or actual rental rates at the Properties.
    Additionally, the Annualized Rent Per Leased Square Foot of Expiring Leases
    includes the effect of retail rental rates at the Properties, which are
    generally higher than office rental rates. Excluding rental payments
    attributable to retail space at the Properties, the Weighted Average
    Annualized Rent Per Leased Square Foot of Expiring Leases would be $23.14.

    TENANT RETENTION AND HISTORICAL LEASE RENEWALS.  The Company works closely
with its tenants to provide a high level of tenant services. The Company
continually seeks to improve its tenant roster by attracting high-quality
tenants to the Properties and seeks to stabilize its rent roll through the early
extension of near-term expiring leases. From January 1, 1994 through December
31, 1997, the Company or its predecessor renewed approximately 75% of the leases
scheduled to expire at the Properties owned and managed by the Company or its
predecessor during such period, constituting renewal of approximately 75% of the
expiring rentable square footage during such period. The following table sets
forth certain historical information regarding tenants at such Properties who
renewed an existing lease at or prior to the expiration of such lease:

(1) The cost of leasing vacant space (i.e., newly-tenating) generally exceeds
    the cost of renewing or retenating occupied space. During the period January
    1, 1994 through December 31, 1997, certain of the Properties were in a
    lease-up phase. In the event the weighted average of total tenant
    improvement costs and leasing commission per square foot were calculated
    assuming a 75% renewal rate on expiring square footage and percentage leased
    rate throughout such period equal to 90% (the percentage leased rate at the
    Properties as of December 31, 1997), such weighted average per square foot
    amount would be $9.55.
 
    HISTORICAL CAPITAL EXPENDITURES.  The Company often acquires underperforming
properties and enhances their value through renovation or repositioning programs
followed by regular capital expenditure programs. Within the next 18 months, the
Company anticipates spending $25 million in redevelopment costs and capital
improvements at the Properties and the Pending Acquisitions, of which
approximately $21 million is designated for the Acquired Properties and the
Pending Acquisitions. These costs are expected to be paid from operating cash
flows, proceeds from debt and equity financings and borrowings under the Credit
Facility.
 
    Prior to acquisition each property under consideration is evaluated to
determine an initial capital budget. The extent of these improvements is
predicated on the physical condition and vacancy at the property, and the
anticipated target market rent. Ongoing capital budgets are determined annually
and are geared toward addressing tenant rollover and changing target market
rent.

673 FIRST AVENUE
 
    673 First Avenue is a 12-story office building that occupies the entire
block front on the west side of First Avenue between East 38th Street and East
39th Street in the Grand Central South submarket of the Manhattan office market.
673 First Avenue contains approximately 422,000 rentable square feet (including
approximately 366,000 square feet of office space, 26,000 square feet of retail
space and a 30,000 square foot garage), with floor plates of approximately
40,000 square feet on all but the top two floors. The building, located three
blocks from the United Nations, was completed in 1928 and converted from a
warehouse/distribution facility to an office building by the Company's
Predecessor in 1989 and 1990. The Company holds a net leasehold interest (which
expires in 2037) in the Property and a ground leasehold interest (which expires
in 2037) in the land underlying the Property. See "Risk Factors--The Company's
Performance and Value are Subject to Risks Associated with the Real Estate
Industry--The expiration of net leases and operating subleases could adversely
affect the Company's financial condition."
 
    At 673 First Avenue, the Company's Predecessor converted a distribution and
warehouse facility into an office property to take advantage of desirable 40,000
square foot floor plates and a strategic location near the United Nations
complex. To accomplish the repositioning, the Company's Predecessor invested
approximately $25 million in the Property for (i) new building entrance, lobby
and storefronts, (ii) complete replacement of the elevator systems, (iii) the
creation of common areas, (iv) entirely reconfigured HVAC and electrical systems
and (v) the build-out of tenant spaces. The repositioning resulted in the
conversion of a 43% occupied warehouse/distribution facility into a 100%
occupied Class B office building within 24 months. The Property's net operating
income (NOI) increased dramatically from approximately $466,000 per annum upon
acquisition to approximately $7.6 million per annum following repositioning and
lease-up (exclusive of net lease payments and debt service payments).

(1) For comparison purposes, according to RELocate, the Direct Weighted Average
    Rental Rate for the direct Class B Grand Central South submarket (which,
    according to RELocate is the area bounded by 32nd Street to 40th Street,
    Fifth Avenue east to the East River) was $28.44 per square foot as of
    December 31, 1997. Direct Weighted Average Rental Rate represents the
    weighted average of asking rental rates for direct Class B space. Asking
    rental rates generally are higher than actual rental rates (which generally
    are not publicly available). Therefore, the Direct Weighted Average Rental
    Rate may not be representative of asking or actual rental rates at 673 First
    Avenue.
 
(2) These rental rates reflect the lease of approximately 100 square feet of
    roof and office space at the Property for the placement of cellular
    telephone antennas and equipment.
 
(3) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    The aggregate undepreciated tax basis of depreciable real property at 673
First Avenue for Federal income tax purposes was $19,193,732 as of December 31,
1997. Depreciation and amortization are computed for Federal income tax purposes
on the straight-line method over lives which range up to 39 years.
 
    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for 673 First Avenue at
this rate for the 1997-98 tax year is $1,236,756 (at a taxable assessed value of
$12,168,000).

470 PARK AVENUE SOUTH
 
    470 Park Avenue South is comprised of two buildings, 468 Park Avenue South
(a 17-story building) and 470 Park Avenue South (a 12-story building), that
occupy the entire blockfront on the west side of Park Avenue South between East
31st and East 32nd Streets in the Park Avenue South/Flatiron submarket of the
Manhattan office market. The buildings are joined together by a single lobby and
common base building systems. 468 Park Avenue South was completed in 1912 and
470 Park Avenue South was completed in 1917. Various portions of the common
areas of both buildings were substantially renovated in 1987, 1990 and 1994. The
Company owns a 100% fee simple interest in this Property. The Property contains
an aggregate of approximately 260,000 rentable square feet (including
approximately 232,000 square feet of office space and approximately 28,000
square feet of retail space), with floor plates of approximately 8,400 square
feet in the 468 building and floor plates of approximately 9,735 square feet in
the 470 building.
 
    As of December 31, 1997, 99% of the rentable square footage in 470 Park
Avenue South was leased (including space for leases that were executed as of
December 31, 1997). The office space was 99% leased and the retail space was
100% leased. The following table sets forth certain information with respect to
the Property:

(1) For comparison purposes, according to RELocate, the Direct Weighted Average
    Rental Rate for the direct Class B Park Avenue South/Flatiron submarket
    (which, according to RELocate, is the area bounded by the northside of 32nd
    Street, the southside of 20th Street, First Avenue and east to Fifth Avenue
    from 20th Street to 23rd Street and Broadway from 24th Street to 32nd
    Street) was $23.64 per square foot as of December 31, 1997. Direct Weighted
    Average Rental Rate represents the weighted average of asking rental rates
    for direct Class B space. Asking rental rates generally are higher than
    actual rental rates (which generally are not publicly available). Therefore,
    the Direct Weighted Average Rental Rate may not be representative of asking
    or actual rental rates at 470 Park Avenue South.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    In 1987, 1990 and 1994, 470 Park Avenue South was substantially renovated by
the Company's predecessor to upgrade the building's amenities and services to
accommodate first class office use. The renovations were completed at a total
cost of approximately $2.6 million and included a significant restoration of the
exterior of the building, a new lobby, a cosmetic upgrade of the elevator cabs,
modernization of the elevator machinery, new plumbing risers, electrical service
upgrades, heating plant replacement, asbestos abatement, installation of a new
roofing system and new windows and replacement of the bathrooms and HVAC systems
on a floor by floor basis.
 
    The aggregate undepreciated tax basis of depreciable real property at 470
Park Avenue South for Federal income tax purposes was $15,283,589 as of December

    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for 470 Park Avenue

$6,435,000).
 
36 WEST 44TH STREET (THE BAR BUILDING)
 
    36 West 44th Street (the Bar Building) is comprised of two buildings, 36
West 44th Street (a 14-story building) and 35 West 43rd Street (a four-story
building), located on the south side of West 44th Street through to the north
side of West 43rd Street between Fifth and Avenue of the Americas in the
Rockefeller Center submarket of the Manhattan office market. The buildings were
completed in 1922 and, as discussed below, a renovation program is underway. The
Property contains approximately 165,000 rentable square feet (including
approximately 148,500 square feet of office space and approximately 16,500
square feet of retail space), with floor plates of approximately 12,000 square
feet at the 44th Street building and floor plates of approximately 2,200 square
feet at the 43rd Street building. The Company owns a leasehold interest (which
expires in 2080) in the land and building at 35 West 43rd Street and fee simple
title to the building at 36 West 44th Street. See "Risk Factors--The Company's
Performance and Value are Subject to Risks Associated with the Real Estate
Industry--The expiration of net leases and operating subleases could adversely
affect the Company's financial condition."
 
    The Bar Building is centrally located on 44th Street between Fifth Avenue
and Avenue of the Americas, in the heart of midtown Manhattan, a block that
includes the headquarters of the Association of the Bar of the City of New York,
the University of Pennsylvania Alumni Club, the Harvard Club, the Algonquin
Hotel, the Royalton Hotel and the Mansfield Hotel. A new Sofitel hotel is
planned for the vacant parcel of land located across the street from the Bar
Building. This location is within two and one half blocks of Grand Central
Terminal, four blocks of Rockefeller Center and five blocks of the Port
Authority Bus Terminal, a major transportation hub for commuters from New
Jersey.
 
    When the Company's Predecessor first purchased its interest in the Bar
Building in October 1996, approximately 35,000 square feet of space was vacant
and approximately 70,000 square feet of space was subject to leases expiring
within 18 months. The Property was nearing the end of a consensual foreclosure
process during which little capital was spent on preventive maintenance or
leasing incentives. Since the purchase of its interest, the Company has
implemented an aggressive leasing and marketing campaign in conjunction with a
strategic property-wide renovation program. The renovation work, which will be
completed at an aggregate cost of approximately $1.1 million, includes roof
repair, facade restoration and steam cleaning, window upgrade, entrance and
lobby upgrade, sidewalk replacement and public corridor renovations. As of
December 31, 1997, approximately 1,600 square feet of space at the Property was
vacant and approximately 99% of the expiring leases were renewed.
 
    As of December 31, 1997, approximately 99% of the rentable square footage in
the Bar Building was leased. The office space was 99% leased and the retail
space was 100% leased. The following table sets forth certain information with
respect to the Property:

(1) For comparison purposes, according to RELocate, the Direct Weighted Average
    Rental Rate for the direct Class B Rockefeller Center submarket (which,
    according to RELocate, is the area between 40th Street to 59th Street along
    Avenue of the Americas and 40th Street to 52nd Street between 5th Avenue and
    Avenue of the Americas) was $28.38 per square foot as of December 31, 1997.
    Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at the Bar Building.
    Additionally, the Annualized Rent Per Leased Square Foot of Expiring Leases
    includes the effect of retail rental rates at this Property, which are
    generally higher than office rental rates. Excluding rental payments
    attributable to retail space at this Property, the weighted average
    Annualized Rent Per Leased Square Foot of Expiring Leases would be $27.04.
 
    The aggregate tax basis of the mortgage indebtedness encumbering The Bar
Building (which was converted to a fee and leasehold interest on April 15, 1998)
for Federal income tax purposes was $17,181,021 as of December 31, 1997.
 
    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for The Bar Building at
this rate for the 1997-98 tax year is $736,382 (at an assessed value of
$7,245,000).

(1) For comparison purposes, according to RELocate the Direct Weighted Average
    Rental Rate for the direct Class B Garment submarket (which, according to
    RELocate is the area from 32nd Street to 40th Street, west of Avenue of the
    Americas to the Hudson River) was $22.71 per square foot as of December 31,
    1997. Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 70 West 36th Street.
 
    In 1984, a complete renovation of 70 West 36th Street was commenced to
convert the Property from a manufacturing loft building into an office building.
The conversion included the creation of a new lobby and building entrance,
installation of office quality public corridors and lavatories, steam cleaning
and repainting of the Property's facade and upgrading and reconfiguration of the
building's plumbing system and electric service. In addition, a monitored,
state-of-the-art security system was installed for the building's entrance and
all tenant spaces. In 1994, further renovations included a new heating plant,
asbestos abatement and elevator modernization, including new cabs. The aggregate
cost of these renovations was approximately $3 million.
 
    70 West 36th Street is located in the Fashion Center Business Improvement
District (BID). The Fashion Center BID encompasses the area bordered to the
north and south by 41st Street and 35th Street, respectively, and to the east
and west by Avenue of the Americas and Ninth Avenue, respectively. The BID
includes approximately 450 buildings with over 5,000 fashion-related tenants
occupying more than 34 million square feet of office space. The Fashion Center
BID provides a private, uniformed security force for on-street, five-day-per
week surveillance and response and a private, uniformed sanitation force. In
addition, the BID has been responsible for the implementation of various special
projects in the area, including the construction of handicapped access curbs and
the installation of enhanced street lighting.

1414 AVENUE OF THE AMERICAS
 
    1414 Avenue of the Americas is a 19-story office building located on the
southeast corner of Avenue of the Americas (Sixth Avenue) and West 58th Street
in the Rockefeller Center submarket of the Manhattan office market. The
building, situated one block from Central Park, was completed in 1923. A
renovation program has commenced at this Property, which includes new windows,
lobby and entrance as well as steam cleaning of the facade, at an estimated
aggregate cost of $660,000. The Company owns a 100% fee simple interest in this
Property. The Property contains approximately 111,000 rentable square feet
(including approximately 103,000 square feet of office space and approximately
8,000 square feet of retail space), with floor plates of approximately 6,400
square feet on all but the top floor.
 
    Located on the easterly blockfront of Sixth Avenue between 57th and 58th
Streets, the Property is at the heart of the Avenue of the Americas corridor
which is host to many of world's most recognizable corporate names in domestic
and international banking, legal services, manufacturing, securities, printing,
publishing, advertising and communications. The Property also benefits from
being strategically located one block north of 57th Street. 57th Street has
become the focal point of the resurgence of high end and specialty retail
development in New York in recent years. Warner Brothers recently expanded their
successful company store on 57th Street and Fifth Avenue. In addition, the Nike
Town Store recently opened on 57th Street between Fifth and Madison Avenues.
High-profile theme retail restaurants such as the Harley Davidson Cafe, the Hard
Rock Cafe, the Motown Cafe, Planet Hollywood and the Jekyll and Hyde Cafe have
all also opened restaurant/theme stores on 57th Street and Avenue of the
Americas. These developments have made the 57th Street corridor a major shopping
and tourist destination which accommodates clientele generated by the area's
concentration of businesses and tourist attractions.
 
    As of December 31, 1997, approximately 99% of the rentable square footage in
1414 Avenue of the Americas was leased (including space for leases that were
executed as of December 31, 1997). The office space was 99% leased and the
retail space was 100% leased. The following table sets forth certain information

(1) For comparison purposes, according to RELocate the Direct Weighted Average
    Rental Rate for the direct Class B Rockefeller Center submarket (which,
    according to RELocate, is the area between 40th Street to 59th Street along
    Avenue of the Americas and 40th Street to 52nd Street between Fifth Avenue
    and Avenue of the Americas) was $28.38 per square foot as of December 31,
    1997. Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 1414 Avenue of the
    Americas. Additionally, the Annualized Rent Per Leased Square Foot of
    Expiring Leases includes the effect of retail rental rates at this Property,
    which are generally higher than office rental rates. Excluding rental
    payments attributable to retail space at this Property, the weighted average
    Annualized Rent Per Leased Square Foot of Expiring Leases would be $28.09.
 
(2) As noted above, 12,200 square feet of the space expiring during 1998 has
    been released to two tenants.
 
(3) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.

(1) For comparison purposes, according to RELocate, the Direct Weighted Average
    Rental Rate for the direct Class B Garment submarket (which, according to
    RELocate, is the area from 32nd Street to 40th Street west of Avenue of the
    Americas to the Hudson River) was $22.71 per square foot as of December 31,
    1997. Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 29 West 35th Street.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    In 1985, 29 West 35th Street was substantially renovated by SL Green at a
total cost of approximately $1 million. The program included the renovation of
the building's lobby, entrance and storefronts, modernization of the elevator
equipment, including new cabs, new electric service and distribution, code
compliant lavatories and fire protection system and a new roof and sidewalk.
 
    29 West 35th Street is located in the Fashion Center BID, which encompasses
the area bordered to the north and south by 41st Street and 35th Street and to
the east and west by Avenue of the Americas and Ninth Avenue, respectively. The
BID includes approximately 450 buildings with over 5,000 fashion-related tenants
occupying more than 34 million square feet of office space. The Fashion Center
BID provides a private, uniformed security force for on-street, five-day-per
week surveillance and response and a private, uniformed sanitation force. In
addition, the BID has been responsible for the implementation of various special
projects in the area, including the construction of handicapped access curbs and
the installation of enhanced street lighting.
 
    The aggregate undepreciated tax basis of depreciable real property at 29
West 35th Street for Federal income tax purposes was $4,801,880 as of December
31, 1997. Depreciation and amortization are computed on the straight-line method
over 39 years.

1372 BROADWAY
 
    1372 Broadway is a 21-story office building located on the northeast corner
of West 37th Street in the Garment submarket of the Manhattan office market. The
building, situated within four blocks of the Port Authority Bus Terminal and
Penn Station, was completed in 1914 and a renovation commenced in the fall of
1997. The Property contains approximately 508,000 rentable square feet
(including approximately 475,000 square feet of office space, approximately
24,000 square feet of retail space and 9,000 square feet of mezzanine space),
with floor plates ranging from 34,000 square feet to 11,000 square feet.

most vibrant development area in New York City. Times Square has undergone
large-scale redevelopment in recent years that has transformed the area into a
popular family entertainment destination. See "--1466 Broadway" below.
 
    The Company has commenced a $2.0 million capital improvement program geared
toward enhancing the infrastructure and marketability of the Property. Included
in this renovation is a new lobby, elevator cab modernization, freight elevator
upgrade, facade restoration and cleaning, sidewalk replacement and asbestos
abatement. Through the repositioning efforts of the Company, the Property was
96% leased as of March 31, 1998.
 
    As of December 31, 1997, approximately 92% of the rentable square footage in
1372 Broadway was leased. The office space was 86% leased and the retail and
mezzanine space were 100% leased. The following table sets forth certain

    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 1372 Broadway.
    Additionally, the Annualized Rent Per Leased Square Foot of Expiring Leases
    includes the effect of retail rental rates at this Property, which are
    generally higher than office rental rates. Excluding rental payments
    attributable to retail space at this Property, the weighted average
    Annualized Rent Per Leased Square Foot of Expiring Leases would be $20.34.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
   
    1372 Broadway is located in the Fashion Center BID, which encompasses the
area bordered to the north and south by 41st Street and 35th Street,

and a private, uniformed sanitation force. In addition, the BID has been
responsible for the implementation of various special projects in the area,
including the construction of handicapped access curbs and the installation of
enhanced street lighting.
 
    The aggregate undepreciated tax basis of depreciable real property at 1372

(1) For comparison purposes, according to RELocate the Direct Weighted Average
    Rental Rate for the direct Class B Rockefeller Center submarket (which,
    according to RELocate, is the area between 40th Street to 59th Street along
    Avenue of the Americas and 40th Street to 52nd Street between Fifth Avenue
    and Avenue of the Americas) was $28.38 per square foot as of December 31,
    1997. Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 1140 Avenue of the
    Americas. Additionally, the Annualized Rent Per Leased Square Foot of
    Expiring Leases includes the effect of retail rental rates at this Property,
    which are generally higher than office rental rates. Excluding rental
    payments attributable to retail space at this Property, the weighted average
    Annualized Rent Per Leased Square Foot of Expiring Leases would be $25.05.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    The aggregate undepreciated tax basis of depreciable real property at 1140
Avenue of the Americas for Federal income tax purposes was $21.2 million as of
December 31, 1997. Depreciation and amortization are computed on the
straight-line method over 39 years.
 
    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for 1140 Avenue of the

(1) For comparison purposes, according to RELocate the Direct Weighted Average
    Rental Rate for the direct Class B Chelsea submarket (which, according to
    RELocate, is the area from 14th Street to 33rd Street between 5th Avenue,
    from 14th Street to 23rd Street, and Broadway from 23rd Street to 33rd
    Street and the Hudson River), was $23.34 per square foot as of December 31,
    1997. Direct Weighted Average Rental Rate represents the weighted average of
    asking rental rates for direct Class B space. Asking rental rates generally
    are higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 50 West 23rd Street.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    The aggregate undepreciated tax basis of depreciable real property at 50
West 23rd Street for Federal income tax purposes was $36.0 million as of
December 31, 1997. Depreciation and amortization are computed on the
straight-line method over 39 years.
 
    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for 50 West 23rd Street
at this rate for the 1997-98 tax year is $977,878 (at an assessed value of
$9,621,000).
 
17 BATTERY PLACE
 
    Formerly an option property, the Company purchased a co-tenancy interest in
17 Battery Place in December 1997. 17 Battery Place is comprised of a 423,000
square foot glass and steel high-rise office
 
                                       85
<PAGE>
structure (the "North Building") built in approximately 1972 and an 799,000
square foot Beaux Art office building (the "South Building") constructed in
two-phases during the 1910's.
 
    The co-tenancy agreement contemplates the formation of a three unit
condominium. The co-tenancy interest of the Company will be converted to two
units comprising 389,000 square feet in the South Building and 422,000 square
feet in the North Building. It is the current intention of the Company to
complete the condominium organization process in the second quarter of 1998. The
Company anticipates spending approximately $6.0 million on a redevelopment
program which will include a new entrance and modernized lobby, facade repair
and restoration, upgraded air conditioning, fire protection and electrical
systems, and redecorated elevator lobby and corridors.
 
    The interest of the Company in 17 Battery is comprised of a co-tenancy
interest in the co-tenancy that owns the land and building, and a note and
mortgage encumbering the interest of the other co-tenant in the co-tenancy. The
note and mortgage held by the Company are in the principal amount of
$15,500,000. The obligation is due and payable on September 30, 1998. The note
bears interest at 12% per annum. The entire interest obligation through maturity
is cash-collateralized, with the cash collateral held by the Company. At the
acquisition of the Property, a co-tenancy was created between a subsidiary of
the Company and Upper, an arm's length third party. Pursuant to the co-tenancy
agreement, the Company acts as managing and leasing agent for the entire
property. The economic risks and benefits of the lower thirteen (13) floors
(excluding certain portions of the ground floor) of the South Building and the
entire North Building are vested with the Company, and these risks and benefits
for the fourteenth and higher floors (together with certain tenanted areas of
the ground floor) of the south building are vested with Upper.
 
    Pursuant to the co-tenancy agreement, the Company is restricted from renting
153,000 rentable square feet of currently vacant space in the portion of the
Property which forms the Company's co-tenancy interest until December 31, 1998,
other than to current tenants of the portion of the Property which forms Upper's
co-tenancy interest.
 
    17 Battery Place is located in the re-emerging World Trade/Battery submarket
of downtown Manhattan. The Property contains 811,000 rentable square feet
(including approximately 802,421 square feet of office space and approximately
8,579 square feet of retail space), with floor plates ranging from 13,325 square
feet to 30,740 square feet. Immediately adjacent to the Property is the Downtown
Athletic Club ("DAC"), home of the Heisman Trophy award. Adjacent to the DAC is
a 300,000 square foot rental apartment building conversion. In addition, the
Property offers unobstructed views of New York Harbor, the Statue of Liberty and
Ellis Island.
 
    As of December 31, 1997, approximately 78.6% of the rentable square footage
in 17 Battery Place was leased (including space for leases that were executed as
of December 31, 1997). The office space was 78.4% leased and the retail space
was 100% leased. The following table sets forth certain information with respect
to the Property:

    As of December 31, 1997, 17 Battery Place was leased to 38 tenants operating
in various industries, including security, not-for-profit and sales training,
two of whom occupied 10% or more of the rentable square footage at the Property.
New York City agencies occupied approximately 288,000 square feet (approximately
35.5% of the Property) under leases expiring on December 31, 2007, that provide
for an

aggregate annualized base rent as of December 31, 1997 of approximately $5.6
million (approximately $19.50 per square foot). The tenant has the right
pursuant to these leases to cancel the term upon 270 days prior notice and
payment of a cancellation penalty in the amount of the unamortized initial
leasing costs. In addition to annualized base rent, this tenant pays real estate
tax escalations and operating escalations in excess of a base year amount.
 
    In addition, a not-for-profit organization occupied approximately 124,000
square feet (approximately 15.3% of the Property) under a lease expiring on
December 31, 2002 that provides for annualized base rent as of December 31, 1997
of approximately $2.6 million (approximately $21.00 per square foot). The tenant
has the right pursuant to the lease to cancel up 99,755 rentable square feet of
the tenancy on six months' prior notice, upon payment of a cancellation penalty
in the amount of the unamortized initial leasing costs for the cancelled space.
In addition to annualized base rent, this tenant pays real estate tax
escalations and operating escalations in excess of a base year amount.
 
    The following table sets out a schedule of the annual lease expirations at
17 Battery Place with respect to leases executed as of December 31, 1997 for
each of the next ten years and thereafter (assuming that no tenants exercise
renewal or cancellation options and that there are no tenant bankruptcies or
other tenant defaults):

(1) For comparison purposes, according to RELocate the Direct Weighted Average
    Rental Rate for the direct Class B World Trade/ Battery submarket (which,
    according to RELocate, is the area bounded by New York Harbor to the south,
    Barclay Street to the north, Broadway to the east and the Hudson River to
    the west), was $22.82 per square foot as of December 31, 1997. Direct
    Weighted Average Rental Rate represents the weighted average of asking
    rental rates for direct Class B space. Asking rental rates generally are
    higher than actual rental rates (which generally are not publicly
    available). Therefore, the Direct Weighted Average Rental Rate may not be
    representative of asking or actual rental rates at 50 West 23rd Street.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.
 
    The aggregate undepreciated tax basis of depreciable real property at 17
Battery Place for Federal income tax purposes was $58.4 million as of December

over 39 years.

    The current real estate tax rate for all Manhattan office properties is
$10.164 per $100 of assessed value. The total annual tax for 17 Battery Place at
this rate for the 1997-98 tax year is $2,469,852 (at an assessed value of

110 EAST 42ND STREET
 
    Directly across from the Grand Hyatt Hotel and Grand Central Station is 110
East 42nd Street, a 250,000 square foot 18-story office building located in the
Grand Central North sub-market of the midtown Manhattan office market.
Distinguished by its landmark lobby and banking hall, this Property was the
Company's first entry into the Grand Central North sub-market. The Property is
occupied by, among others, a major savings bank, law firm and soccer
headquarters. The savings bank intends to leave upon expiration of its lease at
the end of the third quarter of 1998. The rent at this space is significantly
below market and the Company believes that it will appeal to corporate users
that require a unique identity. At December 31, 1997 this Property was 92.5%
leased at an annualized rent per leased square foot of $23.60. The Company
anticipates spending approximately $785,000 on building renovations over the
next 18 months, including lobby renovation, elevator cab upgrades, steam
cleaning and exterior lighting.
 
633 THIRD AVENUE (PARTIAL INTEREST)
 
    The Company's interest in 633 Third Avenue consists of fee title to
condominium units comprising approximately 41,000 square feet of this one
million square foot office building located on the southeast corner of 41st
Street and Third Avenue, in the Grand Central North sub-market of the midtown
Manhattan office market. Located within 3 blocks of Grand Central Terminal, this
Property is 99% leased primarily to a major commercial bank and a sports/health
club and has an annualized rent per leased square foot of $25.38, at December
31, 1997.
 
1466 BROADWAY
 
    Located in the heart of Times Square and the Times Square sub-market of the
midtown Manhattan office market is 1466 Broadway, a 17-story office property.
Built by John Jacob Astor as the Knickerbocker Hotel, the Property was
completely renovated in 1982, converting it to its current use. Today, the
Property is the home to textile and related companies that specialize in men's
and women's fashion. The Property contains approximately 289,000 rentable square
feet (including approximatey 266,244 square feet of office space and
approximately 22,756 square feet of retail space), with floor plates ranging
from 5,500 square feet to 18,000 square feet. The Company anticipates spending
approximately $1 million on building renovations over the next 18 months,
including roof and exterior restoration and asbestos abatement.
 
    The development fervor that surrounds the Property is significant. Within
one block of the Property is the development of Sony and AMC movie theaters,
live theaters including the Selwyn, New Victory and Disney's New Amsterdam,
Madame Tussaud's Wax Museum, the Warner Brothers Store, hotels and the new
office headquarters of Conde Nast and a major law firm.
 
    In addition, this Property enjoys great access to public transportation. It
is directly adjacent to the Times Square Subway Station where a confluence of
subway trains converge. It is one block from the Port Authority Bus Terminal,
which provides transportation to Central and Northern New Jersey and is
equidistant to Grand Central Station and Pennsylvania Station.
 
    As of December 31, 1997, approximately 87% of the rentable square footage in
1466 Broadway was leased (including space for leases that were executed as of
December 31, 1997). The office space was
 
                                       88

(1) For comparison purposes, according to RELocate, the Direct Weighted Average
    Rental Rate for the direct Class B Times Square submarket (which, according
    to RELocate is the area bounded by 40th Street to the south, 51st Street to
    the north, Sixth Avenue to the east and the Hudson River to the west) was
    $24.26 per square foot as of December 31, 1997. Direct Weighted Average
    Rental Rate represents the weighted average of asking rental rates for
    direct Class B space. Asking rental rates generally are higher than actual
    rental rates (which generally are not publicly available). Therefore, the
    Direct Weighted Average Rental Rate may not be representative of asking or
    actual rental rates at 1466 Broadway. Additionally, the Annualized Rent Per
    Leased Square Foot of Expiring Leases includes the effect of retail rental
    rates at this Property, which are generally higher than office rental rates.
    Excluding rental payments attributable to retail space at this Property, the
    weighted average Annualized Rent Per Leased Square Foot of Expiring Leases
    would be $29.57.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.

420 LEXINGTON AVENUE (THE GRAYBAR BUILDING)
 
    The Company purchased the operating sublease at the Graybar Building, a.k.a.
420 Lexington Avenue in March 1998. This 31-story office property sits at the
foot of Grand Central Terminal in the Grand Central North sub-market of the
midtown Manhattan office market. The Property was designed by Sloan and
Robertson and completed in 1927. The building takes its name from its original
owner, the Graybar Electric Company. The Property contains approximately 1.2
million rentable square feet (including approximately 1,150,000 square feet of
office space, 12,260 square feet of mezzanine space and 27,463 square feet of
retail space), with floor plates ranging from 17,000 square feet to 50,000
square feet. The Company anticipates restoring the grandeur of this building
through the implementation of an $8 million capital improvement program geared
toward certain cosmetic upgrades including steam cleaning the facade, new
entrance and storefronts, new lobby, elevator cabs, and elevator lobbies and
corridors.
 
    The Graybar Building offers unsurpassed convenience to transportation. This
Property enjoys excellent accessibility to a wide variety of transportation
options with a direct passageway to Grand Central Station. Grand Central Station
is the major transportation destination for commutation from southern
Connecticut and Westchester County. Major bus and subway lines serve this
Property, as well. The Property is ideally located to take advantage of the
renaissance of Grand Central Terminal, which is being redeveloped into a major
retail/transportation hub containing restaurants such as Michael Jordan's
Steakhouse and retailers such as Banana Republic and Kenneth Cole.
 
    The Graybar Building consists of the building at 420 Lexington Avenue and
fee title to a portion of the land above the railroad tracks and associated
structures which form a portion of the Grand Central Terminal complex in midtown
Manhattan. The Company interest consists of a tenant's interest in a controlling
sublease, as described below. The ownership structure of the Graybar Building is
as follows.
 
    Fee title to the building and the land parcel is owned by an unaffiliated
third party, who also owns landlord's interest under a lease (the "Ground
Lease") the term of which expires December 31, 2008 subject to renewal by the
tenant through December 31, 2029. The Company controls the exercise of this
renewal option through the terms of the subordinate leases described below.
 
    The tenant under the Ground Lease is the holder of the landlord's interest
under a lease (the "Ground Sublease") which is coterminous (except that it ends
on December 30, 2029) and has a complementary renewal option term structure and
control to the Ground Lease. The tenant's interest under the Ground Sublease is
held by an unaffiliated third party. The tenant under the Ground Sublease is the
holder of the landlord's interest under a lease (the "Operating Lease") which is
coterminous (except that it ends on December 28, 2029) and has a complementary
renewal option term structure and control to the Ground Lease. The tenant's
interest under the Operating Lease is held by an unaffiliated third party. The
tenant under the Operating Lease is the holder of the landlord's interest under
a lease (the "Operating Sublease") which is coterminous and has a complementary
renewal option term structure and control to the Ground Lease. The tenant's
interest under the Operating Sublease is held by the Company.

    Street to the north, 5th Avenue to the west and the East River to the east)
    was $31.12 per square foot as of December 31, 1997. Direct Weighted Average
    Rental Rate represents the weighted average of asking rental rates for
    direct Class B space. Asking rental rates generally are higher than actual
    rental rates (which generally are not publicly available). Therefore, the
    Direct Weighted Average Rental Rate may not be representative of asking or
    actual rental rates at the Graybar Building.
 
(2) The differential between Annualized Rent Per Leased Square Foot of Expiring
    Leases and Annualized Rent Per Leased Square Foot of Expiring Leases with
    Future Step-Ups is attributable to significant contractual step-ups in base
    rental rates that exist in certain leases at this Property.

Times Square Redevelopment area, which is being buttressed by new hotel,
entertainment and office development. See "--1466 Broadway" above. The major
tenants at this Property include a sound studio and medical facility. At
December 31, 1997 321 West 44th Street was 96% leased at an annualized rent per
leased square foot of $14.10. The Company anticipates spending approximately
$2.0 million on building renovations over the next 18 months, including facade
restoration and roof replacement.
 
PENDING ACQUISITIONS:
 
440 NINTH AVENUE
 
    The 339,000 square foot office building known as 440 Ninth Avenue is located
one block west of Pennsylvania Station, in the Garment sub-market of the midtown

commutation from Northern and Central New Jersey and New York's Long Island. At
December 31, 1997 this property was 76% leased at an annualized rent per leased
square foot of $18.22. However, the Company believes that its 22,000 square foot
floor plates are significantly attractive to major office space users. This
property is occupied by, among others, a not-for-profit organization, a law firm
and a security company. The purchase price for this property is approximately
$29 million, plus additional expenses of approximately $1.5 million. The Company
intends to complete the closing of this acquisition within 60 days after the
closing of the Offerings. The Company anticipates spending approximately $1.6
million on building renovations over the next 18 months, including a new lobby
and elevator cabs, roof replacement and parapet restoration.

of the midtown Manhattan office market. This 12-story office property is
primarily occupied by a color imaging company and a medical facility. This 93%
occupied property has a retail store that is currently vacant. This property
provides great access to Penn Station, Grand Central Station and the subway and
bus lines. As of December 31, 1997, this property had an annualized rent per
leased square foot of $21.86 and was 79% leased. The purchase price for this

711 THIRD AVENUE
 
   
    The Company has executed a purchase contract to acquire various operating
and ownership positions at 711 Third Avenue in an aggregate amount of $61.0
million, including transaction costs. This 20-story Class B office building is
located in the Grand Central North sub-market of the midtown Manhattan office
market. The property was designed by William Lescaze and constructed in 1955 by
Swig, Weiler & Arnow, a nationally known real estate developer and the owner of
the property. The property contains approximately 524,000 rentable square feet
(including 453,000 square feet of office space, 26,000 square feet of retail
space and a 45,000 square foot garage), with floor plates ranging from 17,000
square feet to 45,000 square feet.
    
 
    The property is strategically located on the east side of Third Avenue
between 44th and 45th Streets, one block from the Graybar Building. Located next
to the Graybar Building is Grand Central Station, which is the major
transportation destination for commutation from southern Connecticut and
Westchester County. Major bus and subway lines serve this property as well.
 
   
    The Company is acquiring the leasehold mortgage (currently in foreclosure)
related to this Pending Acquisition for a net purchase price of $41 million. The
mortgage will be assigned to the Operating Partnership. A subsidiary of the
Company will net sublease the property from the leasehold partnership for a term
expiring in 2023 at a rent substantially equal to the debt service on the
leasehold mortgage plus two pass-throughs of the net rent obligations of the
leasehold described below. The Company will have the option to collapse the
lease/sublease positions and take control of the entire leasehold asset after 12
years in exchange for the distribution to the current leasehold partnership of
Units in the amount of $1 million.
    
 
   
    The Company will also acquire a 50% interest in the fee title to the
property for a purchase price of $19 million plus Units having a value of $1
million. The existing fee partnership will be converted to a co-tenancy. This
co-tenancy will hold the landlord's interest under the existing leasehold. The
initial term of the leasehold expires in 2033. There are five renewal options of
ten years each beyond 2033.
    
 
    The Company will also hold a net leasehold interest (which expires in 2031)
in the land underlying the property. See "Risk Factors--The Company's
Performance and Value are Subject to Risks Associated with the Real Estate
Industry--The expiration of net leases and operating subleases could adversely
affect the Company's financial condition."
 
    As of December 31, 1997 approximately 79% of the rentable square footage in
711 Third Avenue were leased. The office was 73% leased, the retail was 100%
leased and the garage was 100% leased. The following table sets forth-certain
information with respect to the property, but does not count the 45,000 square

    As of December 31, 1997, 711 Third Avenue was leased to 24 tenants operating
in various industries, including publishing, legal services and commercial
shipbuilding, two of whom occupied more than 10% of the rentable square footage
at the property. A magazine publisher occupied approximately 82,444 square feet
(approximately 15.7% of the property) under a lease expiring August, 2010 that
provides for an aggregate annualized base rent as of December 31, 1997 of
approximately $1,813,768 (approximately $22.00 per square foot). In addition,
another publisher occupied approximately 53,454 square feet (approximately 10.2%
of the property) under a lease expiring April, 1998 (which lease was renewed
subsequent to December 31, 1997 and currently expires in April 2000) that
provides for an aggregate annualized base rent as of December 31, 1997 of
approximately $1,250,105 (approximately $23.39 per square foot).
 
    The following table sets out a schedule of the annual lease expirations at
711 Third Avenue with respect to leases executed as of December 31, 1997 for
each of the next ten years and thereafter (assuming that no tenants exercise
renewal or cancellation options that there are no tenant bankruptcies or other
tenant defaults). The table does not include the 45,000 square foot garage at
711 Third Avenue that is operated by a third party pursuant to a management

GENERAL TERMS OF LEASES IN THE MIDTOWN MARKETS
 
    Leases entered into for space in the Midtown Markets typically contain terms
which may not be contained in leases in other U.S. office markets. The initial
term of leases entered into for space in excess of 10,000 square feet in the
Midtown Markets generally is ten to 15 years. The tenant often will negotiate an
option to extend the term of the lease for one or two renewal periods of five
years each. The base rent during the initial term often will provide for agreed
upon increases periodically over the term of the lease. Base rent for renewal
terms, and base rent for the final years of a long-term year lease (in those
leases which do not provide an agreed upon rent during such final years), often
is based upon a percentage of the fair market rental value of the premises
(determined by binding arbitration in the event the landlord and the tenant are
unable to mutually agree upon the fair market value) but not less than the base
rent payable at the end of the prior period. Leases typically do not provide for
increases in rent based upon increases in the consumer price index.
 
    In addition to base rent, the tenant also generally will pay the tenant's
pro rata share of increases in real estate taxes and operating expenses for the
building over a base year. In some leases, in lieu of paying additional rent
based upon increases in building operating expenses, the tenant will pay
additional rent based upon increases in the wage rate paid to porters over the
porters' wage rate in effect during a base year.
 
    Electricity is most often supplied by the landlord either on a submetered
basis or rent inclusion basis (i.e., a fixed fee is included in the rent for
electricity, which amount may increase based upon increases in electricity rates
or increases in electrical usage by the tenant). Base building services other
than electricity (such as heat, air-conditioning and freight elevator service
during business hours, and base building cleaning) typically are provided at no
additional cost, with the tenant paying additional rent only for services which
exceed base building services or for services which are provided other than
during normal business hours.
 
    In a typical lease for a new tenant, the landlord, at its expense, will
deliver the premises with all existing improvements demolished and any asbestos
abated. The landlord also typically will provide a tenant improvement allowance,
which is a fixed sum which the landlord will make available to the tenant to
reimburse the tenant for all or a portion of the tenant's initial construction
of its premises. Such sum typically is payable as work progresses, upon
submission of invoices for the cost of construction. However, in certain leases
(most often for relatively small amounts of space), the landlord will construct
the premises for the tenant.
 
MORTGAGE INDEBTEDNESS
 
    Upon completion of the Offerings, the Company expects to have outstanding
approximately $52.8 million of indebtedness secured by four of the Properties.

limited to an amount less the $140 million which is calculated by several
factors including recent acquisition activity and most recent quarterly property
performance. Outstanding loans under the Credit Facility bear interest at a rate
per annum equal to LIBOR applicable to each interest period plus 130 basis
points to 145 basis points per annum. The Credit Facility requires the Company
to comply with certain covenants, including but not limited to, maintenance of
certain financial ratios. At December 31, 1997 the outstanding amount of
indebtedness under the Credit Facility was $76 million, and the interest rate on
such indebtedness was 7.265% per annum.
 
    On December 30, 1997 the Company entered into a $7 million additional
advance under its existing mortgage loan which is secured by 50 West 23rd
Street. The note bore interest at a rate of LIBOR plus 175 basis points (7.6875%
at December 31, 1997). On April 3, 1998, the interest rate on this note was
fixed at 7.06%, and will mature co-terminous with the underlying mortgage note.
As of April 15, 1998, the current amount of the mortgage note was $21 million.
 
    On March 18, 1998, the Company asked the Credit Facility banking group to
temporarily relieve the Company from its obligations under the financial
covenants of the Credit Facility, in order to close the Acquisition Facility.
The Acquisition Facility, with a borrowing capacity of up to $275 million,
financed the purchase of the Helmsley Properties, paid off the outstanding
balance on the Credit Facility and provided ongoing liquidity for future
acquisition and corporate needs. The term of the this facility is one year. The
interest rate is determined by a schedule of the principal balance of the loan
outstanding and the applicable quarterly period extending from March 18, 1998
through the maturity date. The outstanding principal amount of $240 million
under the Acquisition Facility will be paid from the proceeds of the Offerings.
The Credit Facility will remain committed but unused until the Acquisition
Facility is repaid, at which time the Company will be in compliance with all
financial covenants under the Credit Facility and will again be able to draw
additional funds under the Credit Facility.
 
ENVIRONMENTAL MATTERS
 
    Under various federal, state and local laws, ordinances and regulations, a
current or previous owner or operator of real estate may be required to
investigate and clean up certain hazardous substances released at a property,
and may be held liable to a governmental entity or to third parties for property
damage or personal injuries and for investigation and clean-up costs incurred by
the parties in connection with any contamination. In addition, some
environmental laws create a lien on a contaminated site in favor of the
government for damages and costs it incurs in connection with the contamination.
Such laws often impose such liability without regard to whether the owner or
operator knew of, or was responsible for, the release
 
                                       96
<PAGE>
of hazardous substances. The cost of any required remediation and the owner's
liability therefore as to any property is generally not limited under such
enactments and could exceed the value of the property and/or the aggregate
assets of the owner. The presence of contamination or the failure to remediate
contamination may adversely affect the owner's ability to sell or lease real
estate or to borrow using the real estate as collateral. No assurances can be
given that (i) a prior owner, operator or occupant, such as a tenant, did not
create a material environmental condition not known to the Company, (ii) a
material environmental condition with respect to any Property does not exist, or
(iii) future uses or conditions (including, without limitation, changes in
applicable environmental laws and regulations) will not result in the imposition
of environmental liability.
 
    The Company engaged independent environmental consulting firms to perform
Phase I environmental site assessments on the Properties (except 633 Third
Avenue and 17 Battery Place) and on the Pending Acquisitions in order to assess
existing environmental conditions. All of the Phase I assessments were conducted
since or after March 1997, except for the Bar Building, where a Phase I
assessment was conducted in September 1996. All of the Phase I assessments met
the requirements of the ASTM Standard. Under the ASTM Standard, a Phase I
environmental site assessment consists of a site visit, a historical record
review, a review of regulatory agency data bases and records, interviews, and a
report, with the purpose of indemnifying potential environmental concerns
associated with real estate. The Phase I assessments conducted at the Properties
and Pending Acquisitions also addressed certain issues that were not covered by
the ASTM Standard, including asbestos, radon, lead-based paint and lead in
drinking water. These environmental site assessments did not reveal any known
environmental liability that the Company believes will have a material adverse
effect on the Company's financial condition or results of operations or would
represent a material environmental cost, nor is the Company aware of any such
material environmental liability. See "--Environmental Matters."
 
    The Company maintains a policy of conducting Phase I site inspections for
all acquisitions. Such reports have been completed at or prior to the
acquisitions of all properties acquired since the IPO (except 633 Third Avenue).
These environmental reports did not reveal any environmental liability that
would have a material adverse effect on the Company or its business, nor is the
Company aware of any such material environmental liability.
 
PROPERTY MANAGEMENT AND LEASING SERVICES
 
    The Company (through the Management Entities (as defined in the Glossary)
and the Leasing Corporation) provides management and leasing services for 27
properties (including the Properties owned by the Company) in the New York
metropolitan area. The Company is deemphasizing this business activity because
of the generally short term nature of these assignments and the dilution of
management attention such assignments bring relative to the Company's growth
through acquisitions. The Company plans to complete current assignments, for
which it has been engaged, and may selectively undertake assignments in the
future, where acquisition opportunities are likely.
 
    The Company believes that its fully integrated management structure enhances
its ability to respond to tenant needs and acquisition opportunities while
permitting the Company to maintain control over certain costs associated with
the management and renovation of its properties. The Company maintains a staff
of 47 professionals experienced in the management of Manhattan Class B office
properties. This management team has developed a comprehensive knowledge of the
Class B Manhattan office market, an extensive network of local tenant and other
business relationships and is experienced in acquiring office properties and
repositioning them into profitable Class B properties through intensive full
service management and leasing efforts.
 
    In addition, the Company seeks to capitalize on its market position and
relationships with an extensive network of brokers and tenants to implement a
proactive leasing program. Management believes that its extensive knowledge of
the Class B Manhattan office market enhances its ability to monitor, understand
 
                                       97
<PAGE>
and anticipate the current and future space needs of tenants in its submarkets.
See "Business and Growth Strategies" above.
 
    The Company (through the Management LLC (as defined in the Glossary))
provides management and leasing services for the Properties owned by the Company
as well as leasing services for a portion of the properties in which the Company
owns no interest. In addition, the Company (through the Management Corporation
and the Leasing Corporation) provides management and tenant representation
services for properties in which the Company owns no interest and leasing
services for a portion of such properties.
 
CONSTRUCTION SERVICES
 
    The Company (through the Construction Corporation and the Management
Entities) provides construction services as a part of the Company's management
business and through the Construction Corporation as a general contractor.
 
    CONSTRUCTION MANAGEMENT AS PART OF MANAGEMENT SERVICE AGREEMENTS.  A fee
from 2.5% to 5% of costs provided for or on behalf of third parties incurred for
capital improvements or tenant installations is paid to the Management Entities
for construction management services. These services are comprised of (i)
preconstruction scope of work development and preliminary cost estimating for
the leasing department in connection with potential leasing transactions, plan
review and approval of proposed tenant installation plans; coordination with
property management with respect to tenant installation construction as it
relates to building systems; and, coordination and supervision of tenant's
architects, engineers and contractors in managed properties from the beginning
of lease workletter negotiations through construction of the tenant's build-out
to move-in and (ii) capital improvement programs, including major building
renovations, system upgrades, local law compliance requirements, and completion
of deferred maintenance items requiring replacement (rather than repair).
 
    GENERAL CONTRACTOR SERVICES PROVIDED THROUGH THE CONSTRUCTION
CORPORATION.  The Construction Corporation charges from 5% to 10% provided for
or on behalf of third parties over the costs of construction for the building of
tenant installations in properties managed and leased by the Management Entities
and the Leasing Corporation. This service enables the leasing agent to offer
"turn-key" and "prebuilt" spaces to prospective tenants who want to have space
prepared for them to move into without having to go through the
designing/building process, while holding down the costs of tenant improvements.
 
EMPLOYEES
 
    The Company employs approximately 331 persons. Of such 331 employees,
approximately 65 are "home office" executive and administrative personnel and
approximately 266 are on-site management, operating and administrative
personnel. 251 of these employees are represented by a labor union.
 
COMPETITION
 
    All of the Properties are located in highly developed areas of midtown
Manhattan that include a large number of other office properties. Manhattan is
by far the largest office market in the United States and contains more rentable
square feet than the next six largest central business district office markets
in the United States combined. Of the total inventory of 379 million rentable
square feet in Manhattan approximately 207 million rentable square feet is
comprised of Class A office space and 172 million of Class B office space. Class
A office properties are generally newer than Class B office properties, have
higher finishes and command higher rental rates. Many tenants have been
attracted to Class B properties in part because of their relatively less
expensive rental rates and the tightening of the Class A office market in
midtown Manhattan. See "Market Overview." Consequently, an increase in vacancy
rates and/or a decrease in rental rates for Class A office space would likely
have an adverse effect on rental rates for Class B office space. Also, the
number of competitive Class B office properties in Manhattan (some of which are
newer and better located) could have a material adverse effect on the Company's
ability to lease
 
                                       98
<PAGE>
office space at its properties, and on the effective rents the Company is able
to charge. In addition, the Company may compete with other property owners that
have greater resources than the Company. See "Risk Factors--Competition in its
Marketplace Could Have an Adverse Impact on the Company's Results of
Operations."
 
REGULATION
 
    GENERAL.  Office properties in Manhattan are subject to various laws,
ordinances and regulations, including regulations relating to common areas. The
Company believes that each Property has the necessary permits and approvals to
operate its business.
 
    AMERICANS WITH DISABILITIES ACT.  The Company's properties must comply with
Title III of the ADA to the extent that such properties are "public
accommodations" as defined by the ADA. The ADA may require removal of structural
barriers to access by persons with disabilities in certain public areas of the
Company's properties where such removal is readily achievable. The Company
believes that the Properties are in substantial compliance with the ADA and that
it will not be required to make substantial capital expenditures with respect to
the Properties to address the requirements of the ADA. However, noncompliance
with the ADA could result in imposition of fines or an award of damages to
private litigants. The obligation to make readily achievable accommodations is
an ongoing one, and the Company will continue to assess its properties and to
make alterations as appropriate in this respect.
 
    ENVIRONMENTAL MATTERS.  Under various Federal, state and local laws,
ordinances and regulations, a current or previous owner or operator of real
estate may be required to investigate and clean up certain hazardous substances
released at a property, and may be held liable to a governmental entity or to
third parties for property damage or personal injuries and for investigation and
clean-up costs incurred by the parties in connection with the contamination.
Such laws often impose liability without regard to whether the owner or operator
knew of, or was responsible for, the release of such hazardous substances. The
presence of contamination or the failure to remediate contamination may
adversely affect the owner's ability to sell or lease real estate or to borrow
using the real estate as collateral. Though not a guarantee, the Company as a
matter of policy undertakes Phase I site assessments to identify these risks
before completing any of its acquisitions. See "Risk Factors--Liability for
Environmental Matters Could Adversely Affect the Company's Financial Condition."
 
INSURANCE
 
    The Operating Partnership carries comprehensive liability, fire, extended
coverage and rental loss insurance covering all of the Properties, with policy
specifications and insured limits which the Company believes are adequate and
appropriate under the circumstances. There are, however, certain types of losses
that are not generally insured because they are either uninsurable or not
economically feasible to insure. Should an uninsured loss or a loss in excess of
insured limits occur, the Operating Partnership could lose its capital invested
in the property, as well as the anticipated future revenues from the property
and, in the case of debt which is with recourse to the Operating Partnership,
would remain obligated for any mortgage debt or other financial obligations
related to the property. Any such loss would adversely affect the Company.
Moreover, as a general partner of the Operating Partnership, the Company will
generally be liable for any unsatisfied obligations other than non-recourse
obligations. The Company believes that the Properties will be adequately
insured; however no assurance can be given that material losses in excess of
insurance proceeds will not occur in the future.
 
LEGAL PROCEEDINGS
 
    The Company currently is not a party to any material legal proceedings.
Certain affiliates of the Company are parties to a variety of legal proceedings
relating to their ownership of the Properties and activities with regard to its
construction, management and leasing businesses, respectively, arising in the
ordinary course of business. Because the Company acquired certain of the
Properties subject to associated liabilities, it could become a successor
party-in-interest to certain of these proceedings. The Company believes that
substantially all of this liability is covered by insurance. All of these
matters, taken together, are not expected to have a material adverse impact on
the Company.

                                   MANAGEMENT
 
DIRECTORS AND EXECUTIVE OFFICERS
 
    The Board of Directors of the Company consists of five members, three of
whom are not employees or affiliates of the Company. Pursuant to the Company's
Charter, the Board of Directors is divided into three classes of directors. The
initial terms of the first, second and third classes will expire in 1998, 1999
and 2000, respectively. Beginning in 1998, directors of each class will be
chosen for three-year terms upon the expiration of their current terms and each
year one class of directors will be elected by the stockholders. The Company
believes that classification of the Board of Directors will help to assure the
continuity and stability of the Company's business strategies and policies as
determined by the Board of Directors. Holders of shares of Common Stock will
have no right to cumulative voting in the election of directors. Consequently,
at each annual meeting of stockholders, the holders of a majority of the shares
of Common Stock will be able to elect all of the successors of the class of
directors whose terms expire at that meeting.
 
    The following table sets forth certain information with respect to the
directors and executive officers of the Company:

in the form of cash or Common Stock, at the election of each such director.
Officers of the Company who are directors are not paid any director's
compensation or fees. Pursuant to the Company's Amended 1997 Stock Option and
Incentive Plan (the "Stock Option Plan"), each non-employee director received
options to purchase 6,000 shares of Common Stock (at market price on the date of
grant) which will vest after one year.

(1) These options will vest in three equal annual installments (rounded to the
    nearest whole share) over three years.
 
(2) All options are granted at the fair market value of the Common Stock on the
    date of grant. The exercise price per share was based on the IPO price.
 
(3) In accordance with the rules of the Commission, these amounts are the
    hypothetical gains or "options spreads" that would exist for the respective
    options based on assumed rates of annual compound share appreciation of 5%
    and 10% from the date the options were granted over the full option term. No
    gain to the option is possible without an increase in the price of the
    common shares which would benefit all shareholders.
 
(4) An annual compound share price appreciation of 5% from the IPO price of
    $21.00 per share of Common Stock yields a price of $34.21 per share of
    Common Stock.
 
(5) An annual compound share price appreciation of 10% from the IPO price of
    $21.00 per share of Common Stock yields a price of $54.47 per share of
    Common Stock.
 
(6) In February 1998, options to purchase an additional 100,000 shares of Common
    Stock were granted to Mr. Nettina, under the Stock Option Plan at a price of
    $26.50, the closing market price on February 11, 1998.
 
EMPLOYMENT AND NONCOMPETITION AGREEMENTS
 
    Each of Stephen L. Green, Nancy A. Peck, Steven H. Klein, Benjamin P.
Feldman, Gerard Nocera and Louis A. Olsen have entered into employment and
noncompetition agreements. Each agreement will expire on the third anniversary
of the closing of the IPO (i.e. August 20, 2000), unless otherwise extended,
except that Mr. Olsen's agreement will expire on the first anniversary of the
closing of the IPO (i.e. August 20, 1998), unless extended. Employment under the
agreements may be terminated for "cause" by the Company for: (i) engagement in
conduct that constitutes a felony, (ii) breach of fiduciary duty, gross
negligence or willful misconduct or other conduct against the best interests of
the Company, (iii) a breach of material obligations or covenants under the
agreement, or (iv) an uncured failure to substantially perform the duties
provided for in such agreement. The employee may terminate his or her employment
for "good reason," which includes (i) failure to be elected to offices with the
same or substantially the same duties as provided for in the agreement, (ii) an
uncured breach by the Company of its material obligations under the agreement,
or (iii) a substantial adverse change in the nature or scope of the
responsibility and authority provided in the agreement following a
change-in-control of the Company. If employment is terminated by the Company
"without cause" or by the employee "with good reason," then the employee is
entitled to severance benefits for the remaining period of the agreement
including (i) base salary paid on the same periodic payment dates provided for
in the agreement, (ii) continuation of benefits provided for
 
                                      104
<PAGE>
in the agreement and (iii) continuation of any rights of the employee under the
Company's Stock Option Plan.
 
    The employment and noncompetition agreements, subject to certain exceptions,
prohibit each of such persons from engaging, directly or indirectly, during the
term of his or her employment, in any business which engages or attempts to
engage in, directly or indirectly, the acquisition, development, construction,
operation, management or leasing of any office real estate property within the
New York City metropolitan area (the "Competitive Activities"). The exceptions
include investments listed under "The Properties-- Assets Not Being Transferred
to the Company" and any investments in publicly traded real-estate entities
representing less than 1% of the equity ownership of such entity. Pursuant to
the agreements, each of such persons devotes substantially all of his or her
business time to the Company. The employment and noncompetition agreement of
Stephen L. Green also, subject to certain exceptions, prohibits Mr. Green from
engaging, directly or indirectly, during the Noncompetition Period in any
Competitive Activities. The Noncompetition Period is the period beginning on the
date of the termination of employment and ending on the later of (i) three years
from the closing of the Offering and (ii) one year from the termination of his
employment with the Company.
 
    David J. Nettina has entered into a similar employment and noncompetition
agreement with the Company. Mr. Nettina's agreement also provides for a minimum
yearly bonus of $100,000, the award of options to purchase at least 50,000
shares of Common Stock (exercisable at the IPO price of $21.00 per Common
Share), the award of $200,000 worth of shares of Common Stock on each of the
first, second and third anniversaries of his employment and customary relocation
expenses. The definition of "good reason" in Mr. Nettina's agreement includes a
change-in-control of the Company.
 
    In addition, pursuant to the terms of Mr. Nettina's employment agreement,
Mr. Nettina received a loan from the Company to purchase shares of Common Stock
to be issued under the Stock Option Plan ("Stock Loan"). The principal amount of
the Stock Loan is $300,000. The Stock Loan has a term of three years, accrues
interest at the Federal mid-term "Applicable Federal Rate" ("AFR") as in effect
from time to time, and is secured by the Common Stock purchased and is otherwise
non-recourse. One-third of the Stock Loan (together with accrued interest on the
Stock Loan) will be forgiven each year during the term of the Stock Loan
provided that Mr. Nettina is then employed by the Company. In the event of a
change-in-control of the Company, Mr. Nettina's death or permanent disability or
termination of his employment by the Company without cause, the outstanding
principal amounts of the Stock Loan will be forgiven in full. In the event Mr.
Nettina leaves the employ of the Company or is terminated with cause, the
outstanding amount of the Stock Loan will be immediately due and payable. The
outstanding amount shall be equal to the amount then due and owing, pro rated
for the number of months elapsed for the year in which termination occurs. Mr.
Klein received a similar Stock Loan from the Company in the principal amount of
$500,000, with a term of five years.
 
STOCK OPTION AND INCENTIVE PLAN
 
    In August 1997, the Company adopted the Stock Option Plan. The Stock Option
Plan is administered by the Compensation Committee of the Board of Directors.
Officers and certain other employees of the Company and its subsidiaries
generally are eligible to participate in the Stock Option Plan. Non-employee
Directors of the Company are eligible to receive stock options under the Stock
Option Plan on a limited basis. See "--Compensation of Directors."
 
    The following summary of the Stock Option Plan is qualified in its entirety
by reference to the full text of the Stock Option Plan, a copy of which has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part.
 
    The Stock Option Plan authorizes (i) the grant of stock options that qualify
as incentive stock options under Section 422 of the Code ("ISOs"), (ii) the
grant of stock options that do not so qualify ("NQSOs"), (iii) the grant of
stock options in lieu of cash Directors' fees and employee bonuses, (iv) grants
of shares of
 
                                      105
<PAGE>
Common Stock, in lieu of cash compensation and (v) the making of loans to
acquire shares of Common Stock, in lieu of compensation. The exercise price of
stock options will be determined by the Compensation Committee, but may not be
less than 100% of the fair market value of the shares of Common Stock on the
date of grant in the case of ISOs; provided that, in the case of grants of NQSOs
granted in lieu of cash Directors' fees and employee bonuses, the exercise price
may not be less than 50% of the fair market value of the shares of Common Stock
on the date of grant. The Company has reserved 1,100,000 shares of Common Stock
for issuance under the Stock Option Plan.
 
INCENTIVE COMPENSATION PLAN
 
    The Company has an incentive compensation plan for key officers of the
Company and the Company's subsidiaries and affiliates. This plan provides for
payment of cash bonuses to participating officers after an evaluation of the
officer's performance and the overall performance of the Company has been
completed. The Chief Executive Officer makes recommendations to the Compensation
Committee of the Board of Directors, which makes the final determination for the
award of bonuses in its sole discretion. The Compensation Committee will
determine the amount of such bonuses, if any, for the Chief Executive Officer in
its sole discretion.
 
401(k) PLAN
 
    The Company maintains a 401(k) Savings/Retirement Plan (the "401(k) Plan")
to cover eligible employees of the Company and any designated affiliate.
 
    The 401(k) Plan permits eligible employees of the Company to defer up to 15%
of their annual compensation, subject to certain limitations imposed by the
Code. The employees' elective deferrals are immediately vested and
non-forfeitable upon contribution to the 401(k) Plan.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    The MGCL permits a Maryland corporation to include in its charter a
provision limiting the liability of its directors and officers to the
corporation and its stockholders for money damages except for liability
resulting from (i) actual receipt of an improper benefit or profit in money,
property or services, or (ii) active and deliberate dishonesty established by a
final judgment as being material to the cause of action. The Charter contains
such a provision which eliminates such liability to the maximum extent permitted
by the MGCL.
 
    The Charter authorizes the Company, to the maximum extent permitted by
Maryland law, to obligate itself to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (i) any present or
former director or officer, or (ii) any individual who, while a director of the
Company and at the request of the Company serves or has served another
corporation, limited liability company, partnership, joint venture, trust,
employee benefit plan or any other enterprise as a director, officer, member,
partner or trustee of such corporation, limited liability company, partnership,
joint venture, trust, employee benefit plan or other enterprise from and against
any claim or liability which such persons may incur by reason of his status as a
present or former stockholder, director or officer of the Company. The Bylaws
obligate the Company, to the maximum extent permitted by Maryland law, to
indemnify and to pay or reimburse reasonable expenses in advance of final
disposition of a proceeding to (i) any present or former director or officer who
is made a party to the proceeding by reason of his service in that capacity, or
(ii) any individual who while a director of the Company and at the request of
the Company serves or has served another corporation, limited liability company,
partnership, joint venture, trust, employee benefit plan or any other enterprise
as a director, officer, member, partner or trustee of such corporation, limited
liability company, partnership, joint venture, trust, employee benefit plan or
other enterprise and who is made a party to the proceeding by reason of his
service in that capacity against any claim or liability to which he may become
subject by reason of such service. The Charter and the
 
                                      106
<PAGE>
Bylaws also permit the Company to indemnify and advance expenses to any person
who served a predecessor of the Company in any of the capacities described above
and to any employee or agent of the Company or a predecessor of the Company.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Company's Charter does not) to indemnify a director or officer who has
been successful, on the merits or otherwise, in the defense of any proceeding to
which he is made a party by reason of his service in that capacity. The MGCL
permits a corporation to indemnify its present and former directors and
officers, among others, against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by them in connection with any proceeding
to which they may be made a party by reason of their service in those or other
capacities unless it is established that (i) the act or omission of the director
or officer was material to the matter giving rise to the proceeding and (A) was
committed in bad faith, or (B) was the result of active and deliberate
dishonesty, (ii) the director or officer actually received an improper personal
benefit in money, property or services, or (iii) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful. However, a Maryland corporation may not indemnify for
an adverse judgment in a suit by or in the right of the corporation. In
addition, the MGCL requires the Company, as a condition to advancing expenses,
to obtain (i) a written affirmation by the director or officer of his good faith
belief that he has met the standard of conduct necessary for indemnification by
the Company as authorized by the Bylaws, and (ii) a written statement by or on
his behalf to repay the amount paid or reimbursed by the Company if it shall
ultimately be determined that the standard of conduct was not met.
 
    The Partnership Agreement also provides for indemnification and advance of
expenses of the Company and its officers and directors to the same extent
indemnification and advance of expenses is provided to officers and directors of
the Company in the Charter and Bylaws, and limits the liability of the Company
and its officers and directors to the Operating Partnership and its partners to
the same extent liability of officers and directors of the Company to the
Company and its stockholders is limited under the Charter. See "Partnership
Agreement--Liability and Indemnification."

                     STRUCTURE AND FORMATION OF THE COMPANY
 
THE OPERATING ENTITIES OF THE COMPANY
 
    THE OPERATING PARTNERSHIP.  Substantially all of the Company's assets are
held by, and its operations are through, the Operating Partnership and its
subsidiaries and affiliates. The Company is the sole general partner of the
Operating Partnership and has the exclusive power under the Partnership
Agreement to manage and conduct the business of the Operating Partnership.
Except with respect to the Lock-out Provisions, limited partners generally will
have only limited consent rights. See "Partnership Agreement." The Board of
Directors of the Company manages the affairs of the Company by directing the
affairs of the Operating Partnership. The Operating Partnership cannot be
dissolved for a period of 50 years without the consent of the limited partners,
except in connection with a sale of all or substantially all of its assets,
which also requires the consent of the limited partners. See "Partnership
Agreement." The Company's limited and general partner interests in the Operating
Partnership entitle it to share in cash distributions from, and in the profits
and losses of, the Operating Partnership in proportion to the Company's
percentage interest which currently is approximately 83.8% and will be 90.2%
upon completion of the Offerings.
 
    After a holding period of up to two years following the completion of the
IPO, and at any time thereafter (for as long as the Operating Partnership is in
existence and subject to compliance with the securities laws and the ownership
limits of the Company's organizational documents), limited partners in the
Operating Partnership will be able to have their Units redeemed by the Operating
Partnership for cash or, at the option of the Company, shares of Common Stock on
a one-for-one basis. With each redemption or exchange of Units, the Company's
percentage interest in the operating partnership will increase.
 
    THE MANAGEMENT CORPORATION.  In order to maintain the Company's
qualification as a REIT while realizing income from management contracts with
third parties, all of the management operations with respect to properties in
which the Company will not own 100% of the interest are conducted through the
Management Corporation. The Company, through the Operating Partnership, owns
100% of the non-voting common stock (representing 95% of the total equity) of
the Management Corporation. Through dividends on its equity interest, the
Operating Partnership expects to receive substantially all of the cash flow from
the Management Corporation's operations. All of the voting common stock of the
Management Corporation (representing 5% of the total equity) is held by the
Service Corporation LLC. This controlling interest gives The Service Corporation
LLC the power to elect all directors of the Management Corporation.
 
    THE MANAGEMENT LLC.  All of the management and leasing operations with
respect to the Properties and properties to be acquired by the Company, as well
as leasing operations with respect to a portion of the properties not owned by
the Company, is conducted through the Management LLC. The Operating Partnership
owns a 100% interest in the Management LLC.
 
    THE LEASING CORPORATION.  In order to maintain the Company's qualification
as a REIT while realizing income from leasing and tenant representation services
performed for third parties, leasing operations with respect to a portion of the
properties in which the Company will not own 100% of the interest, as well as
tenant representation services for all of such properties, is conducted through
the Leasing Corporation. The Company, through the Operating Partnership, will
owns 100% of the non-voting common stock (representing 95% of the total equity)
of the Leasing Corporation. Through dividends on its equity interest, the
Operating Partnership expects to receive substantially all of the cash flow from
the Leasing Corporation's operations. All of the voting common stock of the
Leasing Corporation (representing 5% of the total equity) is held by the Service
Corporation LLC. This controlling interest gives the Service Corporation LLC the
power to elect all directors of the Leasing Corporation.
 
    THE CONSTRUCTION CORPORATION.  In order to maintain the Company's
qualification as a REIT while realizing income from construction services all of
the Company's construction operations is conducted through the Construction
Corporation. The Company, through the Operating Partnership, owns 100% of
 
                                      108
<PAGE>
the non-voting common stock (representing 95% of the total equity) of the
Construction Corporation. Through dividends on its equity interest, the
Operating Partnership expects to receive substantially all of the cash flow from
the Construction Corporation's operations. All of the voting common stock of the
Construction Corporation (representing 5% of the total equity) is held by the
Service Corporation LLC. This controlling interest gives the Service Corporation
LLC the power to elect all directors of the Construction Corporation.
 
FORMATION TRANSACTIONS
 
    The Formation Transactions described below (the "Formation Transactions")
were designed to (i) enable the Company to raise the necessary capital to
acquire the Properties, repay certain mortgage indebtedness secured by certain
of the Properties and establish a working capital reserve, (ii) provide a
vehicle for future acquisitions, (iii) enable the Company to comply with certain
requirements under the Code (and the regulations promulgated by the IRS
thereunder (the "Treasury Regulations")) relating to REITs, and (iv) preserve
certain tax advantages for certain participants in the Formation Transactions.
The following Formation Transactions included the following, which were
consummated in connection with the completion of the Offering.
 
    - The Company was organized as a Maryland corporation and the Operating
      Partnership was organized as a Delaware limited partnership in June 1997.
      In connection with the formation of the Company, certain members of SL
      Green management (Nancy A. Peck, Steven H. Klein, Benjamin P. Feldman,
      Gerard Nocera and Louis A. Olsen) were issued an aggregate of 553,616
      shares of Common Stock for total consideration of $3,831 in cash (the
      aggregate par value amount of such stock at the time of issuance).
 
    - Lehman Brothers Holdings Inc. ("LBHI") entered into a loan with Green
      Realty LLC (the "LBHI Loan") pursuant to which LBHI agreed to loan up to
      $46 million to acquire interests in the Initial Properties, to fund
      property related operating expenses, to fund organizational expenses of
      the Company and to purchase Treasury Securities.
 
    - The Company sold 11,615,000 shares of Common Stock in the IPO and
      contributed the net proceeds therefrom to the Operating Partnership in
      exchange for 11,615,000 Units (which, including the issuance of Common
      Stock to Victor Capital, a financial advisor to the Company, and to the
      members of SL Green management referred to herein, represent approximately
      an 81.9% economic interest in the Operating Partnership).
 
    - The Operating Partnership received a contribution of its interests in the
      Properties owned by SL Green immediately prior to the IPO as well as 100%
      of the non-voting common stock of (representing 95% of the economic
      interest in) the Service Corporations from the Property-owning entities,
      the partners or members of such entities and the holders of interests in
      the Service Corporations. As consideration therefor, the Operating
      Partnership issued to such entities, partners or members and holders
      2,383,284 Units (having an aggregate value of approximately $50 million
      based on the IPO price) and approximately $6.4 million.
 
    - The management and leasing business of SL Green with respect to the
      Properties in which the Company will have a 100% ownership interest and
      the tenant representation business with respect to certain properties not
      owned by the Company was transferred to the Management LLC.
 
    - The Operating Partnership was granted (i) an option from 17 Battery LLC to
      acquire its interest in 17 Battery Place from an unaffiliated seller for a
      purchase price of approximately $59 million in cash and (ii) an option
      from 110 Realty LLC to acquire its interest in 110 East 42nd Street from
      an unaffiliated seller for a purchase price of approximately $30 million
      in cash.
 
    - The Operating Partnership acquired interests in 1372 Broadway, 1140 Avenue
      of the Americas and 50 West 23rd Street (together, the "IPO Acquisitions")
      for an aggregate purchase price of
 
                                      109
<PAGE>
      approximately $113.0 million (including a $1.6 million escrow account
      established in connection with the acquisition of 50 West 23rd Street), to
      be funded with net proceeds from the Offering and mortgage financing.
 
    - The Operating Partnership used approximately $82.3 million of net proceeds
      from the IPO to repay mortgage debt encumbering the Properties owned by SL
      Green prior to the IPO and the LBHI Loan (including approximately $9.4
      million in proceeds drawn under the LBHI Loan to fund purchase of the IPO
      Acquisitions).
 
    - The Company issued to Victor Capital 85,600 shares of restricted Common
      Stock and the Operating Partnership will pay $900,000 (funded with
      borrowings under the LBHI Loan and proceeds from the Offering) to Victor
      Capital as consideration for financial advisory services rendered to the
      Company in connection with the Formation Transactions.
 
BENEFITS TO RELATED PARTIES
 
    Certain affiliates of the Company realized certain material benefits in
connection with the Formation Transactions and the IPO, including the following:
 
    - Certain continuing investors (including Stephen L. Green, members of his
      immediate family and unaffiliated partners in the Property-owning
      entities) received 2,383,284 Units in consideration for their interests in
      the Properties, Property-owning entities and the management, leasing and
      construction businesses of SL Green with a total value of approximately
      $50 million (representing approximately 18.1% of the equity of the Company
      on a fully-diluted basis).
 
    - The Operating Partnership used $20 million to repay a portion of the LBHI
      Loan that was made to Green Realty LLC and invested in Treasury Securities
      pledged as collateral therefor (which, upon repayment of the LBHI Loan,
      was released for the benefit of Stephen L. Green).
 
    - Certain members of SL Green management (Nancy A. Peck, Steven H. Klein,
      Benjamin P. Feldman, Gerard Nocera and Louis A. Olsen) own an aggregate of
      553,616 shares of restricted Common Stock (purchased for an aggregate of
      $3,831) with a value of $11.6 million based on the IPO price of $21.00 per
      Common Share.
 
    - Certain members of SL Green management (Stephen L. Green, David J.
      Nettina, Nancy A. Peck, Steven H. Klein, Benjamin P. Feldman, Gerard
      Nocera and Louis A. Olsen) became officers and/or directors of the Company
      and entered into employment and noncompetition agreements with the
      Company. See "Management--Employment and Noncompetition Agreements." Also,
      the Company granted to directors, officers and employees of the Company
      options to purchase an aggregate of 660,000 shares of Common Stock at the
      IPO price of $21.00 per Common Share under the Company's stock option and
      incentive plan, subject to certain vesting requirements (50,000 of such
      options were granted to each of Ms. Peck and Messrs. Klein, Feldman,
      Nocera and Olsen; 75,000 of such options were granted to Mr. Nettina). In
      addition, pursuant to the terms of their employment agreements, Messrs.
      Nettina and Klein received forgivable loans to purchase Common Stock
      issued under such plan in the principal amount of $300,000 and $500,000,
      respectively. See "Management."
 
    - The interests in the Properties, Property-owning entities and Service
      Corporations contributed to the Operating Partnership had a negative book
      value of approximately $7.2 million. As a result of the foregoing
      transactions, continuing investors, members of management and affiliates
      of the Company received benefits with an aggregate value of $82.4 million,
      consisting of (i) Units with an aggregate value of $50 million based on
      the IPO price of $21.00 per Common Share, (ii) $20 million in Treasury
      Securities, (iii) shares of restricted Common Stock of the Company valued
      at $11.6 million based on the IPO price of $21.00 per Common Share and
      (iv) forgivable loans to purchase Common Stock in the aggregate principal
      amount of $800,000.
 
    - The structure of the Formation Transactions provided the Unit recipients
      (including Stephen L. Green, members of his immediate family and
      unaffiliated partners in the Property-owning entities)
 
                                      110
<PAGE>
      the opportunity for deferral of the tax consequences of their contribution
      to the Operating Partnership of their interest in the Properties,
      Property-owning entities and Service Corporations.
 
    - The Service Corporation LLC own all of the voting stock of each of the
      Service Corporations (representing a 5% equity interest therein).
 
    - Pursuant to the Lock-out Provisions, the Company is restricted in its
      ability to sell, or reduce the amount of mortgage indebtedness on, two of
      the Properties (673 First Avenue and 470 Park Avenue South) for up to 12
      years following the completion of the Offering, which could enable certain
      participants in the Formation Transactions (including Stephen L. Green,
      members of his immediate family and unaffiliated partners in the
      Property-owning entities) to defer certain tax consequences associated
      with the Formation Transactions.
 
    - Persons or entities who received Units in the Formation Transactions
      (including entities owned by Stephen L. Green) have registration rights
      with respect to shares of Common Stock issued in exchange for Units.
 
                  POLICIES WITH RESPECT TO CERTAIN ACTIVITIES
 
    The following is a discussion of certain investment, financing and other
policies of the Company. These policies have been determined by the Company's
Board of Directors and may be amended or revised from time to time by the Board
of Directors without a vote of the stockholders, except that (i) the Company
cannot change its policy of holding its assets and conducting its business only
through the Operating Partnership and its affiliates without the consent of the
holders of Units as provided in the Partnership Agreement, (ii) changes in
certain policies with respect to conflicts of interest must be consistent with
legal requirements, and (iii) the Company cannot take any action intended to
terminate its qualification as a REIT without the approval of the holders of a
majority of the outstanding shares of Common Stock.
 
INVESTMENT POLICIES
 
    INVESTMENT IN REAL ESTATE OR INTERESTS IN REAL ESTATE.  The Company will
conduct all of its investment activities through the Operating Partnership and
its affiliates. The Company's primary business objective is to maximize total
return to stockholders through growth in distributable cash flow and
appreciation in the value of its assets. For a discussion of the Properties and
the Company's corporate and growth strategies, see "The Properties" and
"Business and Growth Strategies." In general, it is the Company's policy to
acquire assets primarily for income.
 
    The Company expects to pursue its investment objectives primarily through
the direct or indirect ownership by the Operating Partnership of the Properties
and other acquired office properties. The Company currently intends to invest
primarily in existing improved properties but may, if market conditions warrant,
invest in development projects as well. Furthermore, the Company currently
intends to invest in or develop commercial office properties, primarily in
midtown Manhattan. However, future investment or development activities will not
be limited to any geographic area or product type or to a specified percentage
of the Company's assets. The Company does not have any limit on the amount or
percentage of its assets that may be invested in any one property or any one
geographic area. The Company intends to engage in such future investment or
development activities in a manner which is consistent with the maintenance of
its status as a REIT for Federal income tax purposes. In addition, the Company
may purchase or lease income-producing commercial properties and other types of
properties for long-term investment, expand and improve the real estate
presently owned or other properties purchased, or sell such real estate or other
properties, in whole or in part, if and when circumstances warrant.
 
    The Company also may participate with third parties in property ownership,
through joint ventures or other types of co-ownership. Such investments may
permit the Company to own interests in larger assets without unduly restricting
diversification and, therefore, may add flexibility in structuring its
portfolio. The Company will not, however, enter into a joint venture or
partnership to make an investment that would not otherwise meet its investment
policies.
 
                                      111
<PAGE>
    Equity investments may be subject to existing mortgage financing and other
indebtedness or such financing or indebtedness as may be incurred in connection
with acquiring or refinancing these investments. Debt service on such financing
or indebtedness will have a priority over any distributions with respect to the
Common Stock. Investments also are subject to the Company's policy not to be
treated as an investment company under the Investment Company Act of 1940, as
amended (the "1940 Act").
 
    INVESTMENTS IN REAL ESTATE MORTGAGES.  While the Company's business
objectives emphasize equity investments in commercial real estate, the Company
may, in the discretion of the Board of Directors, invest in mortgages and other
types of equity real estate interests consistent with the Company's
qualification as a REIT. In that regard, the Company has acquired mortgage
interests in the Bar Building and 1372 Broadway which will provide the Company
with substantially all control over, and economic interest derived from, such
Properties. Although the Company does not presently intend to emphasize
investments in mortgages or deeds of trust, it may invest in non-performing
mortgages on an opportunistic basis in order to acquire an equity interest in
the underlying property or in participating or convertible mortgages if the
Company concludes that it would be in the Company's interest to do so.
Investments in real estate mortgages are subject to the risk that one or more
borrowers may default under such mortgages and that the collateral securing such
mortgages may not be sufficient to enable an investor to recoup its full
investment.
 
    SECURITIES OR INTERESTS IN PERSONS PRIMARILY ENGAGED IN REAL ESTATE
ACTIVITIES AND OTHER ISSUERS. Subject to the percentage of ownership limitations
and gross income tests necessary for REIT qualification, the Company also may
invest in securities of other REITs, securities of other entities engaged in
real estate activities or securities of other issuers, including for the purpose
of exercising control over such entities. See "Material Federal Income Tax
Consequences--Taxation of the Company." No such investment will be made,
however, unless the Board of Directors determines that the proposed investment
would not cause the Company or the Operating Partnership to be an "investment
company" within the meaning of the 1940 Act. The Company may acquire all or
substantially all of the securities or assets of other REITs or similar entities
if such investments would be consistent with the Company's investment policies.
 
DISPOSITION POLICIES
 
    The Company does not currently intend to dispose of any of the Properties,
although it reserves the right to do so, subject to the Lock-out Provisions, if,
based upon management's periodic review of the Company's portfolio, the Board of
Directors determines that such action would be in the best interests of the
Company. The tax consequences of the disposition of the Properties may, however,
influence the decision of certain directors and executive officers of the
Company who hold Units as to the desirability of a proposed disposition. See
"Risk Factors--Conflicts of Interests in Connection with the Formation
Transactions and the Business of the Company" and "--Limitations on Ability to
Sell or Reduce the Mortgage Indebtedness on Certain Properties Could Adversely
Affect the Value of the Common Stock."
 
    Any decision to dispose of a Property must be approved by a majority of the
Board of Directors (and in accordance with the applicable partnership
agreement). In addition, under the Lock-out Provisions contained in the
Partnership Agreement, the Company may not sell (except in certain events,
including certain transactions that would not result in the recognition of any
gain for tax purposes) 673 First Avenue and 470 Park Avenue South during the
Lock-out Period without, in the case of either Property, the consent of holders
of 75% of the Units originally issued to limited partners in the Operating
Partnership who immediately prior to completion of the Formation Transactions
owned direct or indirect interests in such Property that remain outstanding at
the time of such vote (other than Units held by the Company and excluding any
such Units the adjusted tax basis of which has been increased, in the hands of
the holder or any predecessor holder thereof, to reflect fair market value
through a taxable disposition or otherwise). The Lock-out Provisions apply even
if it would otherwise be in the best interest of the stockholders for the
Company to sell one or more of these three Properties.
 
                                      112
<PAGE>
FINANCING POLICIES
 
   
    As a general policy, the Company intends to limit its total consolidated
indebtedness, and its pro rata share of unconsolidated indebtedness, so that at
the time any debt is incurred, the Company's Debt Ratio does not exceed 50%.
Upon the completion of the Offerings, the Debt Ratio of the Company will be
approximately 10.8%. The Charter and Bylaws do not, however, limit the amount or
percentage of indebtedness that the Company may incur. In addition, the Company
may from time to time modify its debt policy in light of current economic
conditions, relative costs of debt and equity capital, market values of its
Properties, general conditions in the market for debt and equity securities,
fluctuations in the market price of its Common Stock, growth and acquisition
opportunities and other factors. Accordingly, the Company may increase its Debt
Ratio beyond the limits described above. If this policy were changed, the
Company could become more highly leveraged, resulting in an increased risk of
default on its obligations and a related increase in debt service requirements
that could adversely affect the financial condition and results of operations of
the Company and the Company's ability to make distributions to stockholders.
    
 
    The Company has established its debt policy relative to the total market
capitalization of the Company computed at the time the debt is incurred, rather
than relative to the book value of its assets, a ratio that is frequently
employed, because it believes the book value of its assets (which to a large
extent is the depreciated value of real property, the Company's primary tangible
asset) does not accurately reflect its ability to borrow and to meet debt
service requirements. Total market capitalization, however, is subject to
greater fluctuation than book value, and does not necessarily reflect the fair
market value of the underlying assets of the Company at all times. Moreover, due
to fluctuations in the value of the Company's portfolio of properties over time,
and since any measurement of the Company's total consolidated indebtedness, and
its pro rata share of unconsolidated indebtedness incurred, to total market
capitalization is made only at the time debt is incurred, the Debt Ratio could
exceed the 50% level.
 
    The Company has not established any limit on the number or amount of
mortgages that may be placed on any single property or on its portfolio as a
whole.
 
    Although the Company will consider factors other than total market
capitalization in making decisions regarding the incurrence of debt (such as the
purchase price of properties to be acquired with debt financing, the estimated
market value of properties upon refinancing, and the ability of particular
properties and the Company as a whole to generate sufficient cash flow to cover
expected debt service), there can be no assurance that the Debt Ratio, or any
other measure of asset value, at the time the debt is incurred or at any other
time will be consistent with any particular level of distributions to
stockholders.
 
CONFLICT OF INTEREST POLICIES
 
    Certain holders of Units, including Stephen L. Green, will incur adverse tax
consequences upon the sale of certain of the Properties to be owned by the
Company at the completion of the Formation Transactions and on the repayment of
indebtedness which are different from the tax consequences to the Company and
persons who purchase shares of Common Stock in the Offering. Consequently, such
holders may have different objectives regarding the appropriate pricing and
timing of any such sale or repayment of indebtedness. In addition, pursuant to
the Lock-out Provisions, the Operating Partnership may not sell or reduce the
mortgage indebtedness on 673 First Avenue and 470 Park Avenue South for up to 12
years following completion of the IPO, even if such sale or reduction in
mortgage indebtedness would be in the best interests of the Company's
stockholders. Subject to the Lock-out Provisions, the limited partners of the
Operating Partnership have agreed that in the event of a conflict in the
fiduciary duties owed by the Company to its stockholders and by the General
Partner to such limited partners, the General Partner will fulfill its fiduciary
duties to such limited partnership by acting in the best interest of the
Company's stockholders. See "Partnership Agreement."
 
    The Company has adopted certain policies and entered into agreements with
its executive officers designed to eliminate or minimize certain potential
conflicts of interest. See "Management--Employment and Noncompetition
Agreements." In that regard, the Company has adopted a policy that, without the
approval of a majority of the disinterested Directors, it will not (i) acquire
from or sell to any director, officer or employee of the Company, or any entity
in which a director, officer or employee of the Company beneficially owns more
than a 1% interest, or acquire from or sell to any affiliate of any of the
foregoing,
 
                                      113
<PAGE>
any of the assets or other property of the Company, (ii) make any loan to or
borrow from any of the foregoing persons or (iii) engage in any other
transaction with any of the foregoing persons.
 
    In addition, the Company's Board of Directors is subject to certain
provisions of Maryland law, which are designed to eliminate or minimize certain
potential conflicts of interest. There can be no assurance, however, that these
policies and provisions or these agreements always will be successful in
eliminating the influence of such conflicts, and if they are not successful,
decisions could be made that may fail to reflect fully the interests of all
stockholders.
 
    See "Risk Factors--Conflicts of Interest in Connection with the Formation
Transactions and the Business of the Company."
 
INTERESTED DIRECTOR AND OFFICER TRANSACTIONS
 
    Under Maryland law, a contract or other transaction between the Company and
a director or between the Company and any other corporation or other entity in
which a director is a director or has a material financial interest is not void
or voidable solely on the grounds of such common directorship or interest, the
presence of the director at the meeting at which the contract or transaction is
authorized, approved or ratified or the counting of the director's vote in favor
thereof if (i) the transaction or contract is authorized, approved or ratified
by the board of directors or a committee of the board, after disclosure of the
common directorship or interest, by the affirmative vote of a majority of
disinterested directors, even if the disinterested directors constitute less
than a quorum, or by a majority of the votes cast by disinterested stockholders,
or (ii) the transaction or contract is fair and reasonable to the Company.
 
    Under Delaware law (where the Operating Partnership is formed), the Company,
as general partner, has a fiduciary duty to the Operating Partnership and,
consequently, such transactions also are subject to the duties of care and
loyalty that the Company, as general partner, owes to limited partners in the
Operating Partnership (to the extent such duties have not been eliminated
pursuant to the terms of the Partnership Agreement). The Company will adopt a
policy which requires that all contracts and transactions between the Company,
the Operating Partnership or any of its subsidiaries, on the one hand, and a
director or executive officer of the Company or any entity in which such
director or executive officer is a director or has a material financial
interest, on the other hand, must be approved by the affirmative vote of a
majority of the disinterested directors. Where appropriate in the judgment of
the disinterested directors, the Board of Directors may obtain a fairness
opinion or engage independent counsel to represent the interests of
non-affiliated security holders, although the Board of Directors will have no
obligation to do so.
 
BUSINESS OPPORTUNITIES
 
    Pursuant to Maryland law, each director is obligated to offer to the Company
any business opportunity (with certain limited exceptions) that comes to him and
that the Company reasonably could be expected to have an interest in pursuing.
SL Green continues to own interests in certain other properties as well as
entities that will provide cleaning (and related) services to office properties
and security services to office properties, including the Properties. The
Company does not have any interest in these properties or businesses.
 
POLICIES WITH RESPECT TO OTHER ACTIVITIES
 
    The Company and the Operating Partnership have authority to offer Common
Stock, Preferred Stock, Units, preferred Units or options to purchase capital
stock or Units in exchange for property and to repurchase or otherwise acquire
its Common Stock or Units or other securities in the open market or otherwise
and may engage in such activities in the future. Except in connection with the
Formation Transactions, the Company has not issued Common Stock, Units or any
other securities in exchange for property or any other purpose, and the Board of
Directors has no present intention of causing the Company to repurchase any
Common Stock. The Company may issue Preferred Stock from time to time, in one or
more series, as authorized by the Board of Directors without the need for
stockholder approval. See "Capital Stock--Preferred Stock." The Company has not
engaged in trading, underwriter or agency distribution or sale of securities of
other issuers other than the Operating Partnership, nor has the Company invested
in the securities of other issuers other than the Operating Partnership for the
purposes of exercising control, and does not intend to do so. At all times, the
Company intends to make investments in such a manner as to qualify as a REIT,
unless because of circumstances or changes in the Code (or the
 
                                      114
<PAGE>
Treasury Regulations), the Board of Directors determines that it is no longer in
the best interest of the Company to qualify as a REIT and such determination is
approved by a majority vote of the Company's stockholders, as required by the
Charter. The Company has not made any loans to third parties, although it may in
the future make loans to third parties, including, without limitation, to joint
ventures in which it participates. The Company intends to make investments in
such a way that it will not be treated as an investment company under the 1940
Act. The Company's policies with respect to such activities may be reviewed and
modified or amended from time to time by the Company's Board of Directors
without a vote of the stockholders.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS
 
FORMATION TRANSACTIONS
 
    The terms of the acquisitions of interests in the Initial Properties and the
Service Corporations by the Operating Partnership are described in "Structure
and Formation of the Company--Formation Transactions."
 
CLEANING SERVICES
 
    First Quality Maintenance, L.P. ("First Quality") provides cleaning and
related services with respect to the Properties. First Quality is owned by Gary
Green, a son of Stephen L. Green. First Quality also provides additional
services directly to tenants on a separately negotiated basis. The aggregate
amount of fees to First Quality for services provided (excluding services
provided directly to tenants) was approximately $188,000 in 1994, $164,000 in
1995 and $296,000 in 1996. After the completion of the IPO, the Company retained
First Quality to provide cleaning and related services for the Company's
properties at market rates. In addition, the cleaning entity will continue to
have the non-exclusive opportunity to provide cleaning and related services to
individual tenants at the Company's properties on a basis separately negotiated
with any tenant seeking such additional services. The cleaning entity will
provides such services to individual tenants pursuant to agreements on customary
terms (including at market rates). First Quality leases 3,740 square feet of
space at 70 West 36th Street pursuant to a lease that expires on December 31,
2005 and provides for annual rental payments of approximately $68,660.
 
SECURITY SERVICES
 
    Classic Security LLC ("Classic Security") provides security services with
respect to the Properties. Classic Security is owned by Gary Green, a son of
Stephen L. Green. The aggregate amount of fees for such services was
approximately $24,000 in 1996 (no fees were paid to such entity in 1994 or
1995). Classic Security continues to provide security services for the Company's
properties at market rates.
 
RELATED PARTY TRANSACTIONS
 
    During 1996, HRA, a real estate and management consulting firm of which John
H. Alschuler, Jr., a director nominee of the Company, is the President provided
consulting services for the Leasing Corporation. HRA negotiated certain New York
City benefit programs for Information Builders, Inc., a tenant that was
represented by the Leasing Corporation in connection with its relocation from
1250 Broadway to 2 Penn Plaza. For such services, HRA was paid a total of
$128,962.99 by the Leasing Corporation.
 
                             PARTNERSHIP AGREEMENT
 
    THE FOLLOWING SUMMARY OF THE AGREEMENT OF LIMITED PARTNERSHIP OF THE
OPERATING PARTNERSHIP (THE "PARTNERSHIP AGREEMENT"), INCLUDING THE DESCRIPTIONS
OF CERTAIN PROVISIONS SET FORTH ELSEWHERE IN THIS PROSPECTUS, IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO THE PARTNERSHIP AGREEMENT, WHICH IS FILED AS AN
EXHIBIT TO THE REGISTRATION STATEMENT OF WHICH THIS PROSPECTUS IS A PART.
 
OPERATIONAL MATTERS
 
    GENERAL.  Holders of Units (other than the Company in its capacity as
general partner) will hold a limited partnership interest in the Operating
Partnership, and all holders of Units (including the Company in its capacity as
general partner) will be entitled to share in cash distributions from, and in
the profits and losses of, the Operating Partnership. Each Unit generally will
receive distributions in the same amount paid on each share of Common Stock. See
"Distributions."
 
    Holders of Units will have the rights to which limited partners are entitled
under the Partnership Agreement and, to the extent not limited by the
Partnership Agreement, the Delaware Revised Uniform Limited Partnership Act (the
"Act"). The Units have not been and are not expected to be registered
 
                                      116
<PAGE>
pursuant to any Federal or state securities laws or listed on any exchange or
quoted on any national market system. The Partnership Agreement imposes certain
restrictions on the transfer of Units, as described below.
 
    PURPOSES, BUSINESS AND MANAGEMENT.  The purpose of the Operating Partnership
includes the conduct of any business that may be lawfully conducted by a limited
partnership formed under the Act, except that the Partnership Agreement requires
the business of the Operating Partnership to be conducted in such a manner that
will permit the Company to be classified as a REIT under Section 856 of the
Code, unless the Company ceases to qualify as a REIT for reasons other than the
conduct of the business of the Operating Partnership. Subject to the foregoing
limitation, the Operating Partnership may enter into partnerships, joint
ventures or similar arrangements and may own interests directly or indirectly in
any other entity.
 
    The Company, as the general partner of the Operating Partnership, has the
exclusive power and authority to conduct the business of the Operating
Partnership, subject to the consent of the limited partners in certain limited
circumstances discussed below. No limited partner may take part in the
operation, management or control of the business of the Operating Partnership by
virtue of being a holder of Units.
 
    The Company may not conduct any business other than the business of the
Operating Partnership without the consent of the holders of a majority of the
limited partnership interests (not including the limited partnership interests
held by the Company in its capacity as a limited partner in the Operating
Partnership).
 
    DISTRIBUTIONS.  The Partnership Agreement provides for the quarterly
distribution of Available Cash (as defined below), as determined in the manner
provided in the Partnership Agreement, to the Company and the limited partners
in proportion to their percentage interests in the Operating Partnership.
"Available Cash" is generally defined as net income plus any reduction in
reserves and minus interest and principal payments on debt, capital
expenditures, any additions to reserves and other adjustments. Neither the
Company nor the limited partners are entitled to any preferential or
disproportionate distributions of Available Cash.
 
    BORROWING BY THE OPERATING PARTNERSHIP.  The Company is authorized to cause
the Operating Partnership to borrow money and to issue and guarantee debt as it
deems necessary for the conduct of the activities of the Operating Partnership.
Such debt may be secured by mortgages, deeds of trust, liens or encumbrances on
properties of the Operating Partnership. The Company also may cause the
Operating Partnership to borrow money to enable the Operating Partnership to
make distributions, including distributions in an amount sufficient to permit
the Company, as long as it qualifies as a REIT, to avoid the payment of any
Federal income tax. See "Policies with Respect to Certain Activities--Financing
Policies." Pursuant to the Lock-out Provisions, the Operating Partnership may
not, earlier than one year prior to its maturity, repay the mortgage
indebtedness on 673 First Avenue or 470 Park Avenue South and may not consent to
any such prepayment of mortgage indebtedness on 673 First Avenue or 470 Park
Avenue South (other than pursuant to scheduled amortization) during the Lock-out
Period without, in the case of each such Property, the consent of holders of 75%
of the Units originally issued to limited partners in the Operating Partnership
who immediately prior to completion of the Formation Transactions owned direct
or indirect interests in such Property that remain outstanding at the time of
such vote (whether held by the original recipient of such Units or by a
successor or transferee of the original recipient, but excluding Units held by
the Company and excluding any such Units the adjusted tax basis of which has
been increased, in the hands of the holder or any predecessor holder thereof, to
reflect fair market value through a taxable disposition or otherwise) unless the
repayment is in connection with either a refinancing of the outstanding debt (on
a basis that is nonrecourse to the Operating Partnership and providing for the
least amount of principal amortization that is available on commercially
reasonable terms and permitting certain guarantees by the holders of the Units
originally issued with respect to the affected Property) or an involuntary sale
pursuant to foreclosure of a mortgage securing the debt (or other similar
event). In addition, during
 
                                      117
<PAGE>
the Lock-out Period, the Company is obligated to use commercially reasonable
efforts, commencing one year prior to the stated maturity, to refinance at
maturity (on a basis that is nonrecourse to the Operating Partnership and
providing for the least amount of principal amortization that is available on
commercially reasonable terms and permitting certain guarantees by the holders
of the Units originally issued with respect to the affected Property) the
mortgage indebtedness secured by each of these two Properties at not less than
the principal amount outstanding on the maturity date. Finally, during the
Lock-out Period, the Company may not incur debt secured by either of these two
Properties if the amount of the new debt would exceed the greater of 75% of the
value of the Property securing the debt or the amount of existing debt being
refinanced (plus the costs associated therewith).
 
    REIMBURSEMENT OF THE COMPANY; TRANSACTIONS WITH THE COMPANY AND ITS
AFFILIATES.  The Company will not receive any compensation for its services as
general partner of the Operating Partnership. The Company, however, as a partner
in the Operating Partnership, has the same right to allocations and
distributions as other partners in the Operating Partnership. In addition, the
Operating Partnership will reimburse the Company for substantially all expenses
it incurs relating to the ongoing operation of the Company and offerings of
Units or shares of Common Stock (or rights, options, warrants or convertible or
exchangeable securities).
 
    Except as expressly permitted by the Partnership Agreement, affiliates of
the Company will not engage in any transactions with the Operating Partnership
except on terms that are fair and reasonable and no less favorable to the
Operating Partnership than would be obtained from an unaffiliated third party.
 
    SALES OF ASSETS.  Under the Partnership Agreement, the Company generally has
the exclusive authority to determine whether, when and on what terms the assets
of the Operating Partnership (including the Properties) will be sold, subject to
the Lock-out Provisions. A sale of all or substantially all of the assets of the
Operating Partnership (or a merger of the Operating Partnership with another
entity) generally requires an affirmative vote of the holders of a majority of
the outstanding Units (including Units held by the Company), but also is subject
to the Lock-out Provisions.
 
    Under the Lock-out Provisions, the Operating Partnership may not sell or
otherwise dispose of 673 First Avenue or 470 Park Avenue South (or any direct or
indirect interest therein) during the Lock-out Period (except pursuant to a sale
or other disposition of all or substantially all of the Operating Partnership's
assets approved as described below, an involuntary sale pursuant to foreclosure
of a mortgage secured by one of these Properties or a bankruptcy proceeding, and
certain transactions, including a "Section 1031 like-kind exchange," that would
not result in the recognition of any gain for tax purposes by the holders of
Units issued in the Formation Transactions with respect to these Properties)
without, in the case of each such Property, the consent of holders of 75% of the
Units originally issued to limited partners in the Operating Partnership who
immediately prior to the completion of the Formation Transactions owned direct
or indirect interests in such Property that remain outstanding at the time of
such vote (whether held by the original recipient of such Units or by a
successor or transferee of the original recipient, but excluding Units held by
the Company and excluding any such Units the adjusted tax basis of which has
been increased, in the hands of the holder or any predecessor holder thereof, to
reflect fair market value through a taxable disposition or otherwise). Under the
Lock-out Provisions, a sale or other disposition of all or substantially all of
the assets of the Operating Partnership during the Lock-out Period generally
would require the approval of the holders, as a group, of 75% of the aggregate
Units originally issued with respect to 673 First Avenue and 470 Park Avenue
South that remain outstanding (whether held by the original recipient of such
Units or by a successor or transferee of the original recipient, but excluding
Units held by the Company and excluding any such Units the adjusted tax basis of
which has been increased, in the hands of the holder or any predecessor holder
thereof, to reflect fair market value through a taxable disposition or
otherwise). The consent requirement under the Lockout Provisions, however, would
not apply in the event of a merger or consolidation involving the Operating
Partnership and substantially all of its assets if (i) the transaction would not
result in the recognition of any gain with respect to the Units originally
issued with respect to 673 First Avenue and 470 Park Avenue South, (ii) the
 
                                      118
<PAGE>
Lock-out Provisions would continue to apply with respect to each of these two
Properties, and (iii) the surviving entity agrees to a number of restrictions
and conditions for the benefit of the holders of such Units designed to preserve
the benefit of certain provisions and restrictions in the Partnership Agreement
for the holders of such Units.
 
    NO REMOVAL OF THE GENERAL PARTNER.  The Partnership Agreement provides that
the limited partners may not remove the Company as general partner of the
Operating Partnership with or without cause (unless neither the General Partner
nor its parent entity is a "public company," in which case the General Partner
may be removed for cause).
 
    ISSUANCE OF LIMITED PARTNERSHIP INTERESTS.  The Company is authorized,
without the consent of the limited partners, to cause the Operating Partnership
to issue Units to the Company, to the limited partners or to other persons for
such consideration and upon such terms and conditions as the Company deems
appropriate. The Operating Partnership also may issue partnership interests in
different series or classes, which may be senior to the Units. If Units are
issued to the Company, then the Company must issue shares of Common Stock and
must contribute to the Operating Partnership the proceeds received by the
Company from such issuance. In addition, the Company may cause the Operating
Partnership to issue to the Company partnership interests in different series or
classes of equity securities, which may be senior to the Units, in connection
with an offering of securities of the Company having substantially similar
rights upon the contribution of the proceeds therefrom to the Operating
Partnership. Consideration for partnership interests may be cash or any property
or other assets permitted by the Act. No limited partner has preemptive,
preferential or similar rights with respect to capital contributions to the
Operating Partnership or the issuance or sale of any partnership interests
therein.
 
    AMENDMENT OF THE PARTNERSHIP AGREEMENT.  Generally, the Partnership
Agreement may be amended with the approval of the Company, as general partner,
and limited partners (including the Company) holding a majority of the Units.
Certain provisions regarding, among other things, the rights and duties of the
Company as general partner or the dissolution of the Operating Partnership, may
not be amended without the approval of a majority of the Units not held by the
Company. Notwithstanding the foregoing, the Company, as general partner, has the
power, without the consent of the limited partners, to amend the Partnership
Agreement in certain circumstances. Certain amendments that would affect the
fundamental rights of a limited partner must be approved by the Company and each
limited partner that would be adversely affected by such amendment. In addition,
any amendment that would affect the Lock-out Provisions with respect to 673
First Avenue or 470 Park Avenue South during the Lock-out Period would require,
in the case of each such Property affected by the Amendment, the consent of
holders of 75% of the Units originally issued with respect to such Property that
remain outstanding at the time of such vote (whether held by the original
recipient of such Units or by a successor or transferee of the original
recipient, but excluding Units held by the Company and excluding any such Units
the adjusted tax basis of which has been increased, in the hands of the holder
or any predecessor holder thereof, to reflect fair market value through a
taxable disposition or otherwise).
 
    DISSOLUTION, WINDING UP AND TERMINATION.  The Operating Partnership will
continue until December 31, 2095, unless sooner dissolved and terminated. The
Operating Partnership will be dissolved prior to the expiration of its term, and
its affairs wound up upon the occurrence of the earliest of: (i) the withdrawal
of the Company as general partner without the permitted transfer of the
Company's interest to a successor general partner (except in certain limited
circumstances); (ii) the sale of all or substantially all of the Operating
Partnership's assets and properties (subject to the Lock-out Provisions during
the Lockout Period); (iii) the entry of a decree of judicial dissolution of the
Operating Partnership pursuant to the provisions of the Act; (iv) the entry of a
final non-appealable order for relief in a bankruptcy proceeding of the general
partner, or the entry of a final non-appealable judgment ruling that the general
partner is bankrupt or insolvent (except that, in either such case, in certain
circumstances the limited partners (other than the Company) may vote to continue
the Operating Partnership and substitute a new general partner in place of the
Company); and (v) on or after January 1, 2046, at the option of the
 
                                      119
<PAGE>
Company, in its sole and absolute discretion. Upon dissolution, the Company, as
general partner, or any liquidator will proceed to liquidate the assets of the
Operating Partnership and apply the proceeds therefrom in the order of priority
set forth in the Partnership Agreement.
 
LIABILITY AND INDEMNIFICATION
 
    LIABILITY OF THE COMPANY AND LIMITED PARTNERS.  The Company, as general
partner of the Operating Partnership, is liable for all general recourse
obligations of the Operating Partnership to the extent not paid by the Operating
Partnership. The Company is not liable for the nonrecourse obligations of the
Operating Partnership. Assuming that a limited partner does not take part in the
control of the business of the Operating Partnership and otherwise acts in
conformity with the provisions of the Partnership Agreement and the Act, the
liability of a limited partner for obligations of the Operating Partnership
under the Partnership Agreement and the Act will be limited, subject to certain
exceptions, generally to the loss of such limited partner's investment in the
Operating Partnership represented by his Units. The Operating Partnership will
operate in a manner that the Company deems reasonable, necessary or appropriate
to preserve the limited liability of the limited partners.
 
    EXCULPATION AND INDEMNIFICATION OF THE COMPANY.  The Partnership Agreement
generally provides that the Company, as general partner of the Operating
Partnership, will incur no liability to the Operating Partnership or any limited
partner for losses sustained, liabilities incurred or benefits not derived as a
result of errors in judgment or mistakes of fact or law or of any act or
omission, if the Company carried out its duties in good faith. In addition, the
Company is not responsible for any misconduct or negligence on the part of its
agents, provided the Company appointed such agents in good faith.
 
    The Partnership Agreement also provides for indemnification (including, in
certain circumstances, the advancement of expenses) of the Company, the
directors and officers of the Company and such other persons as the Company may
from time to time designate against any judgments, penalties, fines, settlements
and reasonable expenses that are actually (or will be) incurred by such person
in connection with a proceeding in which any such person is involved, or is
threatened to be involved, as a party or otherwise, unless it is established
that: (i) the act or omission of the indemnified person was material to the
matter giving rise to the proceeding and either was committed in bad faith or
was the result of active and deliberate dishonesty; (ii) the indemnified person
actually received an improper personal benefit in money, property or services;
or (iii) in the case of any criminal proceeding, the indemnified person had
reasonable cause to believe that the act or omission was unlawful.
 
TRANSFERS OF INTERESTS
 
    RESTRICTIONS ON TRANSFER OF THE COMPANY'S INTEREST.  The Company may not
transfer any of its interests as general or limited partner in the Operating
Partnership, except in connection with a merger or sale of all or substantially
all of its assets, in which (i) the limited partners in the Operating
Partnership either will receive, or will have the right to receive,
substantially the same consideration as holders of shares of Common Stock, and
(ii) such transaction has been approved by the holders of a majority of the
interests in the Operating Partnership (including interests held by the
Company). The Lock-out Provisions do not apply to a sale or other transfer by
the Company of its interests as a partner in the Operating Partnership, but they
would apply to transfers of assets of the Operating Partnership undertaken
during the Lock-out Period in connection with or as part of any such transaction
by the Company. See "--Operational Matters--Sales of Assets" above.
 
    RESTRICTIONS ON TRANSFERS OF UNITS BY LIMITED PARTNERS.  For up to two years
after the completion of the Offering, a limited partner may not transfer any of
his rights as a limited partner without the consent of the Company, which
consent the Company may withhold in its sole discretion. Any attempted transfer
in violation of this restriction will be void ab initio and without any force or
effect. Beginning two years after the completion of the IPO, limited partners
(other than the Company) will be permitted to transfer all or any portion of
their Units without restriction as long as they satisfy certain requirements set
forth in the
 
                                      120
<PAGE>
Partnership Agreement. In addition, limited partners will be permitted to
dispose of their Units following the expiration of up to a two-year period
following the completion of the IPO by exercising the redemption right described
below. See "--Redemption of Units" below.
 
    The right of any permitted transferee of Units to become a substituted
limited partner is subject to the consent of the Company, which consent the
Company may withhold in its sole and absolute discretion. If the Company does
not consent to the admission of a transferee of Units as a substituted limited
partner, then the transferee will succeed to all economic rights and benefits
attributable to such Units (including the redemption right described below), but
will not become a limited partner or possess any other rights of limited
partners (including the right to vote).
 
    REDEMPTION OF UNITS.  Subject to certain limitations and exceptions, holders
of Units (other than the Company) have the right to have each of their Units
redeemed by the Operating Partnership at any time beginning two years after the
completion of the Formation Transactions. Unless the Company elects to assume
and perform the Operating Partnership's obligation with respect to the
redemption right, as described below, the limited partner will receive cash from
the Operating Partnership in an amount equal to the market value of the Units to
be redeemed. The market value of a Unit for this purpose will be equal to the
average of the closing trading price of a share of Common Stock on the NYSE for
the ten trading days before the day on which the redemption notice was given to
the Operating Partnership of exercise of the redemption right. In lieu of the
Operating Partnership's acquiring the Units for cash, the Company will have the
right (except as described below, if the Common Stock is not publicly traded) to
elect to acquire the Units directly from a limited partner exercising the
redemption right, in exchange for either cash or shares of Common Stock, and,
upon such acquisition, the Company will become the owner of such Units. The
redemption generally will occur on the tenth business day after the notice to
the Operating Partnership, except that no redemption or exchange can occur if
delivery of shares of Common Stock would be prohibited either under the
provisions of the Company's Charter designed primarily to protect the Company's
qualification as a REIT or under applicable Federal or state securities laws as
long as the shares of Common Stock are publicly traded. See "Capital
Stock--Restrictions on Transfer--Ownership Limits."
 
    In the event that the Common Stock is not publicly traded but another entity
whose stock is publicly traded owns more than 50% of the capital stock of the
Company (referred to as the "Parent Entity"), the redemption right will be
determined by reference to the publicly traded stock of the Parent Entity and
the Company will have the right to elect to acquire the Units to be redeemed for
publicly traded stock of the Parent Entity. In the event that the Common Stock
is not publicly traded and there is no Parent Entity with publicly traded stock,
the redemption right will be based upon the fair market value of the Operating
Partnership's assets at the time the redemption right is exercised (as
determined in good faith by the Company based upon a commercially reasonable
estimate of the amount that would be realized by the Operating Partnership if
each asset of the Operating Partnership were sold to an unaffiliated purchaser
in an arm's length transaction where neither the purchaser nor the seller were
under economic compulsion to enter into the transaction), and the Company and
the Operating Partnership will be obligated to satisfy the redemption right in
cash (unless the redeeming partner, in such partner's sole and absolute
discretion, consents to the receipt of Common Stock), payable on the thirtieth
business day after notice was given to the Operating Partnership of exercise of
the redemption right.
 
ISSUANCE OF ADDITIONAL UNITS AND/OR PREFERENCE UNITS
 
    The Company is authorized at any time, without the consent of the limited
partners, to cause the Operating Partnership to issue additional Units to the
Company, to the limited partners or to other persons for such consideration and
on such terms and conditions as the Company deems appropriate. If Units are
issued to the Company, then the Company must issue a corresponding number of
shares of Common Stock and must contribute to the Operating Partnership the
proceeds, if any, received by the Company from such issuance. In addition, the
Partnership Agreement provides that the Operating
 
                                      121
<PAGE>
Partnership may also issue preferred units and other partnership interests of
different classes and series (collectively, "Preference Units") having such
rights, preferences and other privileges, variations and designations as may be
determined by the Company. Any such Preference Units may have terms, provisions
and rights which are preferential to the terms, provisions and rights of the
Units. Preference Units, however, may be issued to the Company only in
connection with an offering of securities of the Company having substantially
similar rights and the contribution of the proceeds therefrom to the Operating
Partnership. Accordingly, in connection with the PIERS Offering, the Operating
Partnership will issue to the Company    % Series A Convertible, Cumulative
Preference Units that mirror the rights, preferences and other privileges of the
PIERS. No limited partner has preemptive, preferential or similar rights with
respect to capital contributions to the Operating Partnership or the issuance or
sale of any partnership interests therein.
 
FIDUCIARY DUTY
 
    The limited partners have agreed, subject to the Lock-out Provisions, that
in the event of a conflict in the fiduciary duties owed by the Company to its
stockholders and by the General Partner to such limited partners, the General
Partner will fulfill its fiduciary duties to such limited partnership by acting
in the best interests of the Company's stockholders.

                                 CAPITAL STOCK
 
GENERAL
 
    The Company's Charter provides that the Company may issue up to 100 million
shares of common stock, $.01 par value per share ("Common Stock"), 25 million
shares of preferred stock, $.01 par value per share ("Preferred Stock"), and 75
million shares of excess stock, $.01 par value per share ("Excess Stock"). As of
April 24, 1998, 12,292,311 shares of Common Stock were issued and outstanding
and no shares of Preferred Stock were issued and outstanding. Under Maryland
law, stockholders generally are not liable for the corporation's debts or
obligations.
 
COMMON STOCK
 
    All shares of Common Stock outstanding are, and all shares of Common Stock
issuable upon completion of the Common Offering and upon conversion or
redemption of the PIERS offered hereby will be, duly authorized, fully paid and
nonassessable. Subject to the preferential rights of any other shares or series
of stock and to the provisions of the Charter regarding Excess Stock, holders of
shares of Common Stock are entitled to receive dividends on such stock if, as
and when authorized and declared by the Board of Directors of the Company out of
assets legally available therefor and to share ratably in the assets of the
Company legally available for distribution to its stockholders in the event of
its liquidation, dissolution or winding up after payment of or adequate
provision for all known debts and liabilities of the Company.
 
    Subject to the provisions of the Charter regarding Excess Stock, each
outstanding share of Common Stock entitles the holder to one vote on all matters
submitted to a vote of stockholders, including the election of directors, and,
except as provided with respect to any other class or series of stock, the
holders of such shares will possess the exclusive voting power. There is no
cumulative voting in the election of directors, which means that the holders of
a majority of the outstanding shares of Common Stock can elect all of the
directors then standing for election and the holders of the remaining shares
will not be able to elect any directors.
 
    Holders of shares of Common Stock have no preference, conversion, exchange,
sinking fund, redemption or appraisal rights and have no preemptive rights to
subscribe for any securities of the Company. Subject to the provisions of the
Charter regarding Excess Stock, shares of Common Stock will have equal dividend,
liquidation and other rights.
 
    The Charter authorizes the Board of Directors to reclassify any unissued
shares of Common Stock into other classes or series of classes of stock and to
establish the number of shares in each class or series and to set the
preferences, conversion and other rights, voting powers, restrictions,
limitations and restrictions on ownership, limitations as to dividends or other
distributions, qualifications and terms or conditions of redemption for each
such class or series.
 
PREFERRED STOCK
 
   
    The Charter authorizes the Board of Directors to classify any unissued
shares of Preferred Stock and to reclassify any previously classified but
unissued shares of Preferred Stock of any series. Prior to issuance of shares of
each series the Board is required by the MGCL and the Charter to set, subject to
the provisions of the Charter regarding Excess Stock, the terms, preferences,
conversion or other rights, voting powers, restrictions, limitations and
restrictions on ownership, limitations as to dividends or other distributions,
qualifications and terms or conditions of redemption for each such series. Thus,
the Board could authorize the issuance of shares of Preferred Stock with terms
and conditions which could have the effect of delaying, deferring or preventing
a transaction or a change in control of the Company that might involve a premium
price for holders of Common Stock or otherwise be in their best interest. As of
the date hereof, no shares of Preferred Stock are outstanding.
    
 
                                      125
<PAGE>
PIERS
 
    The Board of Directors of the Company has adopted Articles Supplementary
determining the terms of the PIERS as a series of Preferred Stock consisting of
up to 4,600,000 shares, designated as the    % Series A Convertible, Cumulative
Preferred Stock (referred to herein as the PIERS). When issued, the PIERS will
be validly issued, fully paid and nonassessable. Unless converted or redeemed by
the Company, PIERS are subject to mandatory redemption on April 15, 2008.
 
    In connection with the PIERS Offering, the Company will contribute or
otherwise transfer the net proceeds of the sale of the PIERS to the Operating
Partnership and the Operating Partnership will issue to the Company    % Series
A Convertible, Cumulative Preference Units that mirror the rights, preferences
and other privileges of the PIERS. The Operating Partnership will be required to
make all required distributions on such Preference Units prior to any
distribution of cash or assets to the holder of Units or to the holders of any
other equity interest of the Operating Partnership, except for any other series
of Preference Units ranking on a parity with such Preference Units as to
distributions and liquidation, except for distributions required to enable the
Company to maintain its qualification as a REIT.
 
    LISTING.  Application will be made to list the PIERS and the Common Stock
issuable upon conversion or redemption of the PIERS on the NYSE. The PIERS will
be listed under the symbol "SLGPrA". Trading of the PIERS is expected to
commence on the NYSE within 30 days of the closing of the PIERS Offering.
 
    RANKING.  The PIERS will rank senior to the Common Stock as to priority for
receiving distributions and amounts upon liquidation, dissolution or winding up
of the Company.
 
   
    DISTRIBUTIONS.  Holders of the PIERS will be entitled to receive, when and
as authorized by the Board of Directors, out of funds legally available for the
payment of quarterly cumulative cash distributions payable in an amount per
share equal to the greater of (i)    % of the $25.00 liquidation preference per
annum (equivalent to $         per share per annum), payable in equal amounts of
$         per share quarterly or (ii) the cash dividends paid or payable
(determined on each of the Distribution Payment Dates referred to below) on a
number of shares of Common Stock equal to the number of shares of Common Stock
(or portion thereof) into which a PIERS is convertible. Distributions on the
PIERS shall accumulate and be cumulative from the fifteenth day of each January,
April, July and October or, if not a business day, the next succeeding business
day (each, a "Distribution Payment Date"). The first distribution on the PIERS,
which will be paid on July 15, 1998, will be for less than a full quarter. Such
distributions and any distribution payable on the PIERS for any other partial
distribution period will be computed on the basis of a 360-day year consisting
of twelve 30-day months. Distributions will be payable to holders of record as
they appear in the stock records of the Company at the close of business on the
applicable record date, which will be the first day of the calendar month in
which the applicable Distribution Payment Date falls or such other date
designated by the Board of Directors of the Company for the payment of
distributions that is not more than 30 nor less than 10 days prior to such
Distribution Payment Date (each, a "Distribution Record Date").
    
 
    No distribution on the PIERS will be authorized by the Board of Directors if
such authorization, payment or setting apart for payment would violate any
agreement of the Company or is restricted or prohibited by law.
 
    If any PIERS are outstanding, no distributions will be declared or paid or
set apart for payment on any shares of the capital stock of the Company of any
other series ranking, as to distributions or upon liquidation, on a parity with
or junior to the PIERS for any period unless full cumulative distributions have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for such payment on the PIERS for all past
distribution periods and the then current distribution period. When
distributions are not paid in full (or a sum sufficient for such full payment is
not so set apart) upon the PIERS and the shares of any other series of Preferred
Stock ranking on a parity as to distributions with the PIERS, all distributions
declared upon the PIERS and any other series of
 
                                      126
<PAGE>
Preferred Stock ranking on a parity as to distributions with the PIERS will be
declared pro rata so that the amount of distributions declared per share of
PIERS and such other series of Preferred Stock shall in all cases bear to each
other the same ratio that accumulated distributions per share on the PIERS and
such other series of Preferred Stock (which shall not include any accumulation
in respect of unpaid distributions for prior distribution periods if such
Preferred Stock does not have a cumulative distribution) bear to each other. No
interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the PIERS which may be in arrears.
 
    Except as provided in the immediately preceding paragraph, unless full
cumulative distributions on the PIERS have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for payment for all past distribution periods and the then current
distribution period, no distributions (other than in Common Stock or Preferred
Stock ranking junior to the PIERS as to distributions and upon liquidation,
dissolution or winding up of the Company) shall be declared or paid or set aside
for payment or other distribution upon the Common Stock or any Preferred Stock
ranking junior to or on a parity with the PIERS as to distributions or upon
liquidation, dissolution or winding up of the Company, nor shall any Common
Stock or any other series of Preferred Stock ranking junior to or on a parity
with the PIERS as to distributions or upon liquidation, dissolution or winding
up of the Company be redeemed, purchased or otherwise acquired for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any such Stock) by the Company (except by conversion into or
exchange for other stock of the Company ranking junior to the PIERS as to
distributions and upon liquidation, dissolution or winding up of the Company or
by redemptions for the purpose of maintaining the Company's qualification as a
REIT).
 
    Notwithstanding the foregoing, distributions on the PIERS will accumulate
whether or not any of the foregoing restrictions exist, whether or not there are
funds legally available for the payment thereof and whether or not such
distributions are authorized. Accumulated but unpaid distributions on the PIERS
will not bear interest and holders of the PIERS will not be entitled to any
distributions in excess of full cumulative distributions as described above.
 
    Any distribution payment made on the PIERS shall first be credited against
the earliest accumulated but unpaid distribution due with respect to such shares
which remains payable.
 
    If the Company designates any portion of a dividend as a "capital gain
dividend," a U.S. Stockholder's share of such capital gain dividend would be an
amount which bears the same ratio to the total amount of dividends paid to such
U.S. Stockholder for the year as the aggregate amount designated as a capital
gain dividend bears to the aggregate amount of all dividends paid on all classes
of capital stock for the year.
 
    LIQUIDATION PREFERENCE.  In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the holders of the PIERS
will be entitled to receive out of the assets of the Company available for
distribution to stockholders remaining after payment or provisions for payment
of all debts and other liabilities of the Company a liquidation preference of
$25.00 per share, plus an amount equal to any accumulated and unpaid
distributions to the date of payment, before any distribution of assets is made
to holders of Common Stock or any other Preferred Stock ranking junior to the
PIERS as to the distribution of assets upon the liquidation, dissolution or
winding up of the Company. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of PIERS will have no
right or claim to any of the remaining assets of the Company. None of (i) a
consolidation or merger of the Company with or into another entity, (ii) a
merger of another entity with or into the Company, (iii) a statutory share
exchange by the Company or (iv) a sale, lease or conveyance of all or
substantially all of the Company's property or business shall be considered a
liquidation, dissolution or winding up of the Company. If, upon any voluntary or
involuntary liquidation, dissolution or winding up of the Company, the assets of
the Company are insufficient to make the full payment due to holders of the
PIERS and the corresponding amounts payable on all other Preferred Stock of the
Company ranking on a parity with the PIERS as to the distribution of assets upon
the liquidation, dissolution or winding up of the Company,
 
                                      127
<PAGE>
then the holders of the PIERS and all other such Preferred Stock shall share
ratably in any such distribution of assets in proportion to the full liquidating
distributions to which they would otherwise be respectively entitled.
 
    REDEMPTION.  Except in certain circumstances relating to the preservation of
the Company's status as a REIT for federal income tax purposes, the PIERS will
not be redeemable prior to July 15, 2003. On and after July 15, 2003, the PIERS
will be redeemable by the Company, in whole or in part, at the option of the
Company, for such number of shares of Common Stock as equals the liquidation
preference of the PIERS to be redeemed divided by the Conversion Price as of the
opening of business on the date set for such redemption (equivalent to a
conversion rate of       shares of Common Stock per each PIERS) (the "Stock
Redemption Right"). The Company may exercise the Stock Redemption Right only if
for 20 trading days within any period of 30 consecutive trading days, including
the last day of such period, the closing price of the Common Stock on the NYSE
exceeds $         per share, subject to adjustment under the circumstances
described below under "--Conversion Price Adjustments." To exercise the Stock
Redemption Right, the Company must issue a press release announcing the
redemption prior to the opening of business on the second trading day after the
conditions described in the preceding sentence have, from time to time, been
met, but may not issue a press release prior to May 15, 2002.
 
    Notice of redemption pursuant to the Stock Redemption Right will be given by
mail or by publication (with subsequent prompt notice by mail) to the holders of
the PIERS not more than four business days after the Company issues the press
release announcing its intention to redeem the PIERS. The redemption date will
be a date selected by the Company not less than 30 nor more than 60 days after
the date on which the Company issues such press release.
 
    On and after July 15, 2003, the PIERS may be redeemed at the option of the
Company, in whole or from time to time in part, at the following redemption
prices per PIERS if redeemed during the twelve-- month period beginning July 15
of the year indicated below, plus, in each case, all distributions accumulated
and unpaid on the PIERS to the date of such redemption (the "Cash Redemption
Right"), upon giving notice as provided below:

    The Company will not exercise its option to redeem the PIERS pursuant to the
Cash Redemption Right unless the redemption price (other than the portion
thereof consisting of accumulated and unpaid distributions) for the exercise of
the Cash Redemption Right is paid solely out of the sale proceeds of other stock
of the Company, which may include other series of Preferred Stock, and from no
other source.
 
    Notice of redemption pursuant to the Cash Redemption Right will be mailed,
not less than 30 nor more than 60 days prior to the PIERS Redemption Date, to
each holder of record of PIERS to be redeemed, notifying such holder of the
Company's election to redeem such shares, stating (i) the date fixed for
redemption thereof, (ii) the redemption price, (iii) the number of shares to be
redeemed (and, if fewer than all the PIERS are to be redeemed, the number of
shares to be redeemed from such holder), (iv) the place(s) where the PIERS are
to be surrendered for payment, (v) that distributions on the shares to be
redeemed will cease to accumulate on such redemption date and (vi) the date upon
which the holder's conversion rights, if any, as to such shares shall terminate.
 
    The PIERS will be subject to mandatory redemption on April 15, 2008 at a
price of $25.00 per PIERS, plus accumulated and unpaid distributions to the
redemption date.
 
                                      128
<PAGE>
    Any date fixed for redemption pursuant to the foregoing provisions is
referred to as a "PIERS Redemption Date."
 
    If fewer than all of the outstanding PIERS are to be redeemed pursuant to
the Stock Redemption Right or the Cash Redemption Right, the PIERS to be
redeemed will be determined pro rata or by lot or in such other manner as
prescribed by the Company's Board of Directors. If such redemption is to be by
lot and as a result of such redemption any holder of PIERS would become a holder
of a number of PIERS in excess of the Ownership Limit because such holder's
PIERS were not redeemed, or were only redeemed in part, then, except in certain
instances, the Company will redeem the requisite number of PIERS of such holder
such that he will not hold in excess of the Ownership Limit subsequent to such
redemption. In addition, the Company may redeem PIERS in certain circumstances
relating to the maintenance of its ability to qualify as a REIT for federal
income tax purposes.
 
    On or after the PIERS Redemption Date, each holder of PIERS to be redeemed
must present and surrender the certificates representing his PIERS to the
Company at the place designated in the applicable notice and thereupon the
redemption price of such shares will be paid to or on the order of the person
whose name appears on such certificate representing PIERS as the owner thereof
and each surrendered certificate will be canceled. If fewer than all the shares
represented by any such certificate representing PIERS are to be redeemed, a new
certificate will be issued representing the unredeemed shares. From and after
the PIERS Redemption Date (unless the Company defaults in payment of the
redemption price), all distributions on the PIERS called for redemption will
cease to accumulate and all rights of the holders thereof, except the right to
receive the redemption price thereof (including all accumulated and unpaid
distributions to the PIERS Redemption Date), will cease and terminate and such
shares will not thereafter be transferred (except with the consent of the
Company) on the Company's books, and such shares shall not be deemed to be
outstanding for any purpose whatsoever. At its election, the Company, prior to a
PIERS Redemption Date relating to its Cash Redemption Right, may irrevocably
deposit the redemption price (including accumulated and unpaid distributions) of
the PIERS so called for redemption in trust for the holders thereof with a bank
or trust company, in which case the notice to holders of the PIERS to be
redeemed will (i) state the date of such deposit, (ii) specify the office of
such bank or trust company as the place of payment of the redemption price and
(iii) require such holders to surrender the certificates representing such
shares at such place on or about the date fixed in such redemption notice (which
may not be later than such PIERS Redemption Date) against payment of the
redemption price (including all accumulated and unpaid distributions to such
PIERS Redemption Date). Any moneys so deposited which remain unclaimed by the
holders of the PIERS at the end of two years after the PIERS Redemption Date
will be returned by such bank or trust company to the Company.
 
    Notwithstanding the foregoing, unless full cumulative distributions on all
PIERS have been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for payment for all past
distribution periods and the current distribution period, no PIERS will be
redeemed unless all outstanding PIERS are simultaneously redeemed; provided,
however, that the foregoing will not prevent the purchase or acquisition of
PIERS pursuant to a purchase or exchange offer made on the same terms to holders
of all outstanding PIERS. In addition, unless full cumulative distributions on
all outstanding PIERS have been or contemporaneously are declared and paid or
declared and a sum sufficient for the payment thereof set apart for payment for
all past distributions periods and the then current distribution period, the
Company will not purchase or otherwise acquire directly or indirectly any PIERS
or any Preferred Stock ranking junior to or on a parity with the PIERS as to
distributions or upon liquidation, dissolution or winding up of the Company
(except by conversion into or exchange for stock of the Company ranking junior
to the PIERS as to distributions and upon liquidation, dissolution or winding up
of the Company or by redemptions for the purposes of maintaining the Company's
qualification as a REIT).
 
                                      129
<PAGE>
    Fractional shares of Common Stock are not to be issued upon redemption of
the PIERS pursuant to the Share Redemption Right, but, in lieu thereof, the
Company will pay a cash adjustment based on the current market price of the
Common Stock on the trading day prior to the PIERS Redemption Date.
 
    VOTING RIGHTS.  Holders of PIERS will not have any voting rights, except as
provided by law and as described below. Whenever distributions on any PIERS are
in arrears for six or more quarterly periods, the holders of PIERS (voting
separately as a class with all other series of Preferred Stock upon which like
voting rights have been conferred and are exercisable) will be entitled to vote
for the election of two additional directors of the Company who will be elected
for a one year term. Such election shall be held at a special meeting of the
stockholders and at each subsequent annual meeting until all arrearages and the
distributions on the PIERS and such other series of Preferred Stock upon which
like voting rights have been conferred and are exercisable for the then current
distribution period have been fully paid or a sum sufficient for the full
payment thereof has been set aside. Vacancies for directors elected by holders
of PIERS and any other such series of Preferred Stock shall be filled by the
remaining director so elected then in office or, if there is no such remaining
director, by vote of holders of a majority of the outstanding PIERS and any
other such series of Preferred Stock voting as a single class. A director
elected by the holders of PIERS and any other such series of Preferred Stock may
be removed with or without cause and only by vote of holders of a majority of
the outstanding PIERS and any other such series of Preferred Stock voting as a
single class.
 
    So long as any PIERS remain outstanding, the Company will not, without the
affirmative vote or consent of the holders of at least two-thirds of PIERS
outstanding at the time, given in person or by proxy, either in writing or at a
meeting (voting separately as a class), (i) authorize or create, or increase the
authorized or issued amount of, any class or series of capital stock of the
Company ranking prior to PIERS with respect to the payment of distributions or
the distribution of assets upon liquidation, dissolution or winding up of the
Company, or reclassify any authorized shares of capital stock of the Company
into such shares, or create, authorize or issue any obligation or security
convertible or exchangeable into or evidencing the right to purchase any such
shares; or (ii) amend, alter or repeal the provisions of the Charter or the
Articles Supplementary for the PIERS, whether by merger or consolidation (an
"Event") or otherwise, so as to materially and adversely affect any right,
preference, privilege or voting power of such PIERS or the holders thereof;
provided, however, with respect to the occurrence of any of the Events set forth
in (ii) above, so long as PIERS remain outstanding with the terms thereof
materially unchanged, taking into account that upon the occurrence of an Event,
the Company may not be the surviving entity, the occurrence of any such Event
will not be deemed to materially adversely affect such rights, preferences,
privileges or voting powers of holders of PIERS; and provided further that (x)
any increase in the amount of the authorized Preferred Stock or the creation or
issuance of any other series of Preferred Stock, or (y) any increase in the
amount of authorized PIERS or any other series of Preferred Stock, in each case
ranking on a parity with or junior to the PIERS with respect to payment of
distributions and the distribution of assets upon liquidation, dissolution or
winding up of the Company, will not be deemed to materially and adversely affect
such rights, preferences, privileges or voting powers.
 
    The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required will be
effected, all outstanding PIERS have been converted, redeemed or called for
redemption and sufficient funds shall have been deposited in trust to effect
such redemption.
 
    CONVERSION RIGHTS.  Subject to the restrictions on transfer and ownership
described below in "-- Restrictions on Ownership and Transfer," the PIERS will
be convertible in whole or in part at any time, at the option of the holders
thereof, into Common Stock at a conversion price of $         per share of
Common Stock (equivalent to a conversion rate of       shares of Common Stock
for each PIERS), subject to adjustment as described below (the "Conversion
Price"). The right to convert PIERS called for redemption will terminate at the
close of business on a PIERS Redemption Date. For information as to notices of
redemption, see "-- Redemption" above.
 
                                      130
<PAGE>
    Conversion of PIERS, or a specified portion thereof, may be effected by
delivering certificates representing PIERS together with written notice of
conversion and a proper assignment of such certificates to the office of
American Stock Transfer & Trust Co., the conversion agent for the PIERS.
 
    Each conversion will be deemed to have been effected immediately prior to
the close of business on the date on which the certificates representing PIERS
shall have been surrendered and notice shall have been received by the Company
as aforesaid (and if applicable, payment of any amount equal to the distribution
payable on such shares shall have been received by the Company as described
below) and the conversion shall be at the Conversion Price in effect at such
time and on such date.
 
    Holders of PIERS at the close of business on a Distribution Record Date will
be entitled to receive the distribution payable on such shares on the
corresponding Distribution Payment Date notwithstanding the conversion of such
shares following such Distribution Record Date and prior to such Distribution
Payment Date. However, certificates representing PIERS surrendered for
conversion during the period between the close of business on any Distribution
Record Date and ending with the opening of business on the corresponding
Distribution Payment Date (except shares converted after the issuance of a
notice of redemption with respect to a PIERS Redemption Date during such period
or coinciding with such Distribution Payment Date) must be accompanied by
payment of an amount equal to the distribution payable on such shares on such
Distribution Payment Date. A holder of PIERS on a Distribution Record Date who
(or whose transferee) tenders any such shares for conversion into Common Stock
on such Distribution Payment Date will receive the distribution payable by the
Company on such PIERS on such date, and the converting holder need not include
payment of the amount of such distribution upon surrender of certificates
representing such PIERS for conversion. Except as provided above, the Company
will make no payment or allowance for unpaid distributions, whether or not in
arrears, on converted shares or for distribution on the Common Stock that is
issued upon such conversion.
 
    Fractional shares of Common Stock will not be issued upon conversion but, in
lieu thereof, the Company will pay a cash adjustment based on the current market
price of the Common Stock at the close of business on the trading day prior to
the conversion date.
 
    CONVERSION PRICE ADJUSTMENTS.  The Conversion Price is subject to adjustment
upon certain events, including (i) the payment of distributions payable in
Common Stock on any class or series of shares of Capital Stock of the Company,
(ii) the issuance to all holders of Common Stock of certain rights or warrants
entitling them to subscribe for or purchase Common Stock (or securities
convertible into or exchangeable for Common Stock) at a price per share less
than the fair market value per share of Common Stock, (iii) subdivisions,
combinations and reclassifications of Common Stock, (iv) distributions to all
holders of Common Stock of evidences of indebtedness of the Company or assets
(including securities, but excluding those rights, warrants and distributions
referred to above and distributions paid in cash out of equity, including
revaluation equity, applicable to Common Stock), (v) distributions consisting
exclusively of cash (excluding any cash portion of distributions referred to in
clause (iv) to all holders of Common Shares to the extent such distributions,
combined with (A) all such cash distributions made within the preceding 12
months in respect of which no adjustment has been made plus (B) any cash and the
fair market value of other consideration payable in respect of any tender offers
by the Company for Common Stock concluded within the preceding 12 months in
respect of which no adjustment has been made, but only to the extent that the
consideration payable in respect of such tender offers exceeds the current
market price of the Common Shares acquired in such tender offers, exceeds 15% of
the Company's market capitalization (being the product of the then current
market price of the Common Stock times the number of shares of Common Stock then
outstanding) on the record date for such distribution and (vi) a tender offer
made by the Company or any Subsidiary for all or any portion of the Common Stock
shall expire and such tender offer shall require payment to stockholders of
aggregate consideration having a fair market value that combined with (Y) the
aggregate of the cash plus the fair market value, as of the expiration of such
tender offer, of consideration payable in respect of any other tender offer by
the Company or any subsidiary for all or any portion of the Common Stock
expiring within 12 months preceding the expiration
 
                                      131
<PAGE>
of such tender offer and in respect of which no adjustment to this section (vi)
has been made, but only to the extent that the consideration payable in respect
of such expired tender offer exceeds the current market price of the Common
Stock acquired in such tender offer, and (Z) the aggregate amount of any
distributions to all holders of Common Stock made exclusively in cash within the
12 months preceding the expiration of such tender offer and in respect of which
no adjustment pursuant to section (v) has been made, exceeds 15% of the product
of the current market price per share of the Common Stock as of the last time
tenders could have been made pursuant to such tender offer times the number of
Common Stock outstanding (including tendered shares). In addition to the
foregoing adjustments, the Company will be permitted to make such reductions in
the Conversion Price as it considers to be advisable in order that any event
treated for federal income tax purposes as a dividend of stock or stock rights
will not be taxable to the holders of Common Stock.
 
    In case the Company shall be a party to any transactions (including, without
limitation, a merger, consolidation, statutory share exchange, tender offer for
all or substantially all of the Common Stock or sale of all or substantially all
of the Company's assets), in each case as a result of which Common Stock will be
converted into the right to receive shares of common stock or beneficial
interest, securities or other property (including cash or any combination
thereof), each PIERS will thereafter be convertible into the kind and amount of
shares of stock or beneficial interest, securities and other property receivable
(including cash or any combination thereof) upon the consummation of such
transaction by a holder of that number of shares of Common Stock or fraction
thereof into which one PIERS was convertible immediately prior to such
transaction, assuming such holder of Common Stock failed to exercise any rights
of election (provided that if the kind and amount of stock or beneficial
interest, securities and other property so receivable is not the same for each
non-electing share, the kind and amount so receivable by each non-electing share
shall be deemed to be the kind and amount received per share by a plurality of
non-electing shares). The Company may not become a party to any such transaction
unless the terms thereof are consistent with the foregoing. No adjustment of the
Conversion Price is required to be made in any case until cumulative adjustments
amount to 1% or more of the Conversion Price. Any adjustments not so required to
be made will be carried forward and taken into account in subsequent
adjustments.
 
    OWNERSHIP LIMIT.  The restrictions on transferability and ownership
described in "-- Restrictions on Transfer" below apply to the PIERS.
 
EXCESS STOCK
 
    For a description of Excess Stock, see "--Restrictions on Transfer."
 
POWER TO ISSUE ADDITIONAL SHARES OF COMMON STOCK AND PREFERRED STOCK
 
    The Company believes that the power of the Board of Directors to issue
additional authorized but unissued shares of Common Stock or Preferred Stock and
to classify or reclassify unissued shares of Common Stock or Preferred Stock and
thereafter to cause the Company to issue such classified or reclassified shares
of stock will provide the Company with increased flexibility in structuring
possible future financings and acquisitions and in meeting other needs which
might arise. The additional classes or series, as well as the Common Stock, will
be available for issuance without further action by the Company's stockholders,
unless such action is required by applicable law or the rules of any stock
exchange or automated quotation system on which the Company's securities may be
listed or traded. Although the Board of Directors has no intention at the
present time of doing so, it could authorize the Company to issue a class or
series that could, depending upon the terms of such class or series, delay,
defer or prevent a transaction or a change of control of the Company that might
involve a premium price for holders of Common Stock or otherwise be in their
best interest.
 
                                      132
<PAGE>
    The Company intends to furnish its stockholders with annual reports
containing audited consolidated financial statements and an opinion thereon
expressed by an independent public accounting firm and quarterly reports for the
first three quarters of each fiscal year containing unaudited financial
information.
 
RESTRICTIONS ON TRANSFER
 
   
    For the Company to qualify as a REIT under the Code, among other things, not
more than 50% in value of its outstanding capital stock may be owned, directly
or indirectly, by five or fewer individuals (defined in the Code to include
certain entities) during the last half of a taxable year (other than the first
taxable year) (the "Five or Fewer Requirement"), and such shares of capital
stock must be beneficially owned by 100 or more persons during at least 335 days
of a taxable year of 12 months (other than the first taxable year) or during a
proportionate part of a shorter taxable year. Pursuant to the Code, Common Stock
held by certain types of entities, such as pension trusts qualifying under
Section 401(a) of the Code, United States investment companies registered under
the Investment Company Act of 1940, partnerships, trusts and corporations, will
be attributed to the beneficial owners of such entities for purposes of the Five
or Fewer Requirement (I.E., the beneficial owners of such entities will be
counted as persons). See "Material Federal Income Tax Consequences." In order to
protect the Company against the risk of losing it status as a REIT due to a
concentration of ownership among its stockholders, the Charter, subject to
certain exceptions, provides that no stockholder may own, or be deemed to own by
virtue of the attribution provisions of the Code, more than 9.0% (the "Ownership
Limit") of the aggregate number or value of the Company's outstanding shares of
Common Stock. The Articles Supplementary creating the Preferred Stock designated
as the PIERS will provide that no stockholder may own, or be deemed to own by
virtue of the attribution provisions of the Code, more than 9.0% in value of the
Company's outstanding capital stock or more than 20.0% of the aggregate number
or value of the Company's outstanding PIERS. Any direct or indirect ownership of
shares of stock in excess of the Ownership Limit or that would result in the
disqualification of the Company as a REIT, including any transfer that results
in shares of capital stock being owned by fewer than 100 persons or results in
the Company being "closely held" within the meaning of Section 856(h) of the
Code, shall be null and void, and the intended transferee will acquire no rights
to the shares of capital stock. The foregoing restrictions on transferability
and ownership will not apply if the Board of Directors determines that it is no
longer in the best interests of the Company to attempt to qualify, or to
continue to qualify, as a REIT. The Board of Directors may, in its sole
discretion, waive the Ownership Limit if evidence satisfactory to the Board of
Directors and the Company's tax counsel is presented that the changes in
ownership will not then or in the future jeopardize the Company's REIT status
and the Board of Directors otherwise decides that such action is in the best
interest of the Company.
    
 
    Shares of capital stock owned, or deemed to be owned, or transferred to a
stockholder in excess of the Ownership Limit will automatically be converted
into shares of Excess Stock that will be transferred, by operation of law, to
the trustee of a trust for the exclusive benefit of one or more charitable
organizations described in Section 170(b)(1)(A) and 170(c) of the Code (the
"Charitable Beneficiary"). The trustee of the trust will be deemed to own the
Excess Stock for the benefit of the Charitable Beneficiary on the date of the
violative transfer to the original transferee-stockholder. Any dividend or
distribution paid to the original transferee-stockholder of Excess Stock prior
to the discovery by the Company that capital stock has been transferred in
violation of the provisions of the Company's Charter shall be repaid to the
trustee upon demand. Any dividend or distribution authorized and declared but
unpaid shall be rescinded as void ab initio with respect to the original
transferee-stockholder and shall instead be paid to the trustee of the trust for
the benefit of the Charitable Beneficiary. Any vote cast by an original
transferee-stockholder of shares of capital stock constituting Excess Stock
prior to the discovery by the Company that shares of capital stock have been
transferred in violation of the provisions of the Company's Charter shall be
rescinded as void ab initio. While the Excess Stock is held in trust, the
original transferee-stockholder will be deemed to have given an irrevocable
proxy to the trustee to vote the capital stock for the benefit of the Charitable
Beneficiary. The trustee of the trust may transfer the interest in the trust
representing the Excess Stock to any person whose ownership of the shares of
capital stock converted into such Excess
 
                                      133
<PAGE>
Stock would be permitted under the Ownership Limit. If such transfer is made,
the interest of the Charitable Beneficiary shall terminate and the proceeds of
the sale shall be payable to the original transferee-stockholder and to the
Charitable Beneficiary as described herein. The original transferee-stockholder
shall receive the lesser of (i) the price paid by the original
transferee-stockholder for the shares of capital stock that were converted into
Excess Stock or, if the original transferee-stockholder did not give value for
such shares (E.G., the stock was received through a gift, devise or other
transaction), the average closing price for the class of shares from which such
shares of capital stock were converted for the ten trading days immediately
preceding such sale or gift, and (ii) the price received by the trustee from the
sale or other disposition of the Excess Stock held in trust. The trustee may
reduce the amount payable to the original transferee-stockholder by the amount
of dividends and distributions relating to the shares of Excess Stock which have
been paid to the original transferee-stockholder and are owned by the original
transferee-stockholder to the trustee. Any proceeds in excess of the amount
payable to the original transferee-stockholder shall be paid by the trustee to
the Charitable Beneficiary. Any liquidation distributions relating to Excess
Stock shall be distributed in the same manner as proceeds of a sale of Excess
Stock. If the foregoing transfer restrictions are determined to be void or
invalid by virtue of any legal decision, statue, rule or regulation, then the
original transferee-stockholder of any shares of Excess Stock may be deemed, at
the option of the Company, to have acted as an agent on behalf of the Company in
acquiring the shares of Excess Stock and to hold the shares of Excess Stock on
behalf of the Company.
 
    In addition, the Company will have the right, for a period of 90 days during
the time any shares of Excess Stock are held in trust, to purchase all or any
portion of the shares of Excess Stock at the lesser of (i) the price initially
paid for such shares by the original transferee-stockholder, or if the original
transferee-stockholder did not give value for such shares (E.G., the shares were
received through a gift, devise or other transaction), the average closing price
for the class of stock from which such shares of Excess Stock were converted for
the ten trading days immediately preceding such sale or gift, and (ii) the
average closing price for the class of stock from which such shares of Excess
Stock were converted for the ten trading days immediately preceding the date the
Company elects to purchase such shares. The Company may reduce the amount
payable to the original transferee-stockholder by the amount of dividends and
distributions relating to the shares of Excess Stock which have been paid to the
original transferee-stockholder and are owed by the original
transferee-stockholder to the trustee. The Company may pay the amount of such
reductions to the trustee for the benefit of the Charitable Beneficiary. The
90-day period begins on the later date of which notice is received of the
violative transfer if the original transferee-stockholder gives notice to the
Company of the transfer or, if no such notice is given, the date the Board of
Directors determines that a violative transfer has been made.
 
    These restrictions will not preclude settlement of transactions through the
New York Stock Exchange.
 
    All certificates representing shares of stock will bear a legend referring
to the restrictions described above.
 
    Each stockholder shall upon demand be required to disclose to the Company in
writing any information with respect to the direct, indirect and constructive
ownership of capital stock of the company as the Board of Directors deems
necessary to comply with the provisions of the Code applicable to REITs, to
comply with the requirements of any taxing authority or governmental agency or
to determine any such compliance.
 
    The Ownership Limit may have the effect of delaying, deferring or preventing
a change in control of the Company unless the Board of Directors determines that
maintenance of REIT status is no longer in the best interest of the Company.

TRANSFER AGENT, REGISTRAR, CONVERSION AGENT AND DISTRIBUTION DISBURSING AGENT
 
    The transfer agent, registrar and distribution disbursing agent for the
Common Stock is, and the transfer agent, registrar, conversion agent and
distribution disbursing agent for the PIERS will be, American Stock Transfer &
Trust Company.
 
GLOBAL SECURITIES
 
    The PIERS will be evidenced by one or more global certificates (the "Global
Securities"), which will be deposited with, or on behalf of, The Depository
Trust Company, New York, New York ("DTC"), and registered in the name of Cede &
Co. ("Cede"), as DTC's nominee.
 
    Holders may hold their interests in any of the Global Securities directly
through DTC, or indirectly through organizations which are participants in DTC
("Participants"). Transfers between Participants will be effected in the
ordinary way in accordance with DTC rules and will be settled in immediately
available funds.
 
    Holders who are not Participants may beneficially own interests in a Global
Security held by DTC only through Participants, including certain banks,
brokers, dealers, trust companies and other parties that clear through or
maintain a custodial relationship with a Participant, either directly or
indirectly, and have indirect access to the DTC system ("Indirect
Participants"). So long as Cede, as the nominee of DTC, is the registered owner
of any Global Security, Cede for all purposes will be considered the sole holder
of such Global Security. Except as provided below, owners of beneficial
interests in a Global Security will not be entitled to have certificates
registered in their names, will not receive or be entitled to receive physical
delivery of certificates in definitive form, and will not be considered the
holder thereof.
 
    The Company will not have any responsibility for the performance by DTC or
their Participants or Indirect Participants of their respective obligations
under the rules and procedures governing their operations. DTC has advised the
Company that it will take any action permitted to be taken by a holder of PIERS
only at the direction of one or more Participants whose accounts are credited
with DTC interests in a Global Security.
 
    DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a "banking
organization" within the meaning of the New York Banking Law, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and to facilitate the clearance and settlement
of securities transactions, such as transfers and pledges, among Participants in
deposited securities through electronic book--entry changes to accounts of its
Participants, thereby eliminating the need for physical movement of securities
certificates. Participants include securities brokers and dealers, banks, trust
companies, clearing corporations and certain other organizations. Certain of
such Participants (or their representatives), together with other entities, own
DTC. The rules applicable to DTC and its Participants are on file with the
Commission.
 
    Purchases of PIERS under the DTC system must be made by or through
Participants, which will receive a credit for the PIERS on DTC's records. The
ownership interest of each actual purchaser of each PIERS (a "Beneficial Owner")
is in turn to be recorded on the Participant's and Indirect Participants'
records. Beneficial Owners will not receive written confirmation from DTC of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Transfers of
ownership interests in the PIERS are to be accomplished by entries made on the
books of Participants acting on behalf of Beneficial Owners. Beneficial Owners
will not receive certificates representing their ownership interests in PIERS,
except in the event that use of the book-entry system for the PIERS is
discontinued.
 
                                      135
<PAGE>
    The deposit of PIERS with DTC and their registration in the name of Cede
effect no change in beneficial ownership. DTC has no knowledge of the actual
Beneficial Owners of the PIERS; DTC's records reflect only the identity of the
Participants whose accounts such PIERS are credited, which may or may not be the
Beneficial Owners. The Participants will remain responsible for keeping account
of their holdings on behalf of their customers.
 
    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. Such laws may, and the
restrictions described under "Notice to Investors" shall, impair the ability to
transfer beneficial interests in the Global Security.
 
    Redemption notices shall be sent to Cede. If less than all of the PIERS
represented by the Global Securities are being redeemed, DTC's practice is to
determine by lot the amount of the interest of each Participant therein to be
redeemed.
 
    Conveyance of notices and other communications by DTC to Participants, by
Participants to Indirect Participants and by Participants and Indirect
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements that may be in effect from
time to time.
 
    Distributions and other payments in respect of the PIERS will be made to DTC
by wire transfer of immediately available funds. DTC's practice is to credit
Participants' accounts on the payable date in accordance with their respective
holdings shown on DTC's records unless DTC has reason to believe that it will
not receive payment on the payable date. Payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such Participant
and not of DTC or the Company, subject to any statutory or regulatory
requirements as may be in effect from time to time. Distributions and other
payments in respect of the PIERS to DTC is the responsibility of the Company;
disbursement of such payments to Participants shall be the responsibility of
DTC, and disbursement of such payments to the Beneficial Owners shall be the
responsibility of Participants and Indirect Participants. The Company will not
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Global
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

    CERTAIN PROVISIONS OF MARYLAND LAW AND THE COMPANY'S CHARTER AND BYLAWS
 
    THE FOLLOWING SUMMARY OF CERTAIN PROVISIONS OF MARYLAND LAW AND OF THE
CHARTER AND BYLAWS OF THE COMPANY DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT
TO AND QUALIFIED IN ITS ENTIRETY BY REFERENCE TO MARYLAND LAW AND THE CHARTER
AND BYLAWS OF THE COMPANY, COPIES OF WHICH ARE EXHIBITS TO THE REGISTRATION
STATEMENT OF WHICH THIS PROSPECTUS IS A PART.
 
    The Charter and the bylaws of the Company (the "Bylaws") contain certain
provisions that could make more difficult an acquisition or change in control of
the Company by means of a tender offer, a proxy contest or otherwise. These
provisions are expected to discourage certain types of coercive takeover
practices and inadequate takeover bids and to encourage persons seeking to
acquire control of the Company to negotiate first with the Board of Directors.
The Company believes that the benefits of these provisions outweigh the
potential disadvantages of discouraging such proposals because, among other
things, negotiation of such proposals might result in an improvement of their
terms. The description set forth below is intended as a summary only and is
qualified in its entirety by reference to the Charter and the Bylaws, which have
been filed as exhibits to the Registration Statement of which this Prospectus is
a part. See also "Capital Stock--Restrictions on Transfer."
 
CLASSIFICATION AND REMOVAL OF BOARD OF DIRECTORS; OTHER PROVISIONS
 
    The Company's Charter provides for the Board of Directors to be divided into
three classes of directors, with each class to consist as nearly as possible of
an equal number of directors. The term of office of the first class of directors
expires at the 1998 annual meeting of stockholders; the term of the second class
of directors will expire at the 1999 annual meeting of stockholders; and the
term of the third class will expire at the 2000 annual meeting of stockholders.
At each annual meeting of stockholders, the class of directors to be elected at
such meeting will be elected for a three-year term, and the directors in the
other two classes will continue in office. Because stockholders will have no
right to cumulative voting for the election of directors, at each annual meeting
of stockholders the holders of a majority of the shares of Common Stock will be
able to elect all of the successors to the class of directors whose term expires
at that meeting.
 
    The Company's Charter also provides that, except for any directors who may
be elected by holders of a class or series of capital stock other than the
Common Stock, directors may be removed only for cause and only by the
affirmative vote of stockholders holding at least two-thirds of all the votes
entitled to be cast for the election of directors. Vacancies on the Board of
Directors may be filled by the affirmative vote of the remaining directors and,
in the case of a vacancy resulting from the removal of a director, by the
stockholders by a majority of the votes entitled to be cast for the election of
directors. A vote of stockholders holding at least two-thirds of all the votes
entitled to be cast thereon is required to amend, alter, change, repeal or adopt
any provisions inconsistent with the foregoing classified board and director
removal provisions. Under the Charter, the power to amend the Bylaws of the
Company is vested exclusively in the Board of Directors, and the stockholders do
not have any power to adopt, alter or repeal the Bylaws absent amendment to the
Charter to confer such power. These provisions may make it more difficult and
time-consuming to change majority control of the Board of Directors of the
Company and, thus, may reduce the vulnerability of the Company to an unsolicited
proposal for the takeover of the Company or the removal of incumbent management.
 
    Because the Board of Directors will have the power to establish the
preferences and rights of additional series of capital stock without stockholder
vote, the Board of Directors may afford the holders of any series of senior
capital stock preferences, powers and rights, voting or otherwise, senior to the
rights of holders of shares of Common Stock. The issuance of any such senior
capital stock could have the effect of delaying or preventing a change in
control of the Company. The Board of Directors, however, currently does not
contemplate the issuance of any series of capital stock other than shares of
Common Stock.
 
                                      137

    See "Management--Directors and Executive Officers" for a description of the
limitations on liability of directors of the Company and the provisions for
indemnification of directors and officers provided for under applicable Maryland
law and the Charter.
 
BUSINESS COMBINATION STATUTE
 
    The MGCL establishes special requirements with respect to "business
combinations" between Maryland corporations and "interested stockholders" unless
exemptions are applicable. Among other things, the law prohibits for a period of
five years a merger and other specified or similar transactions between a
company and an interested stockholder and requires a super majority vote for
such transactions after the end of the five-year period.
 
    For this purpose, "interested stockholders" are all persons owning
beneficially, directly or indirectly, 10% or more of the outstanding voting
stock of a Maryland corporation, and affiliates and associates of the Maryland
corporation (which are, generally, any entities controlling, controlled by, or
under common control with, the Maryland corporation) which owned beneficially,
directly or indirectly, 10% or more of the outstanding voting stock of such
Maryland corporation. "Business combinations" include any merger or similar
transaction subject to a statutory vote and additional transactions involving
transfers of assets or securities in specified amounts to interested
stockholders or their affiliates. Unless an exemption is available, transactions
of these types may not be consummated between a Maryland corporation and an
interested stockholder or its affiliates for a period of five years after the
date on which the stockholder first became an interested stockholder.
Thereafter, the transaction may not be consummated unless recommended by the
board of directors and approved by the affirmative vote of at least 80% of the
votes entitled to be cast by all holders of outstanding shares of voting stock
and two-thirds of the votes entitled to be cast by all holders of outstanding
shares of voting stock other than the interested stockholder. A business
combination with an interested stockholder that is approved by the board of
directors of a Maryland corporation at any time before an interested stockholder
first becomes an interested stockholder is not subject to the special voting
requirements. An amendment to a Maryland corporation's charter electing not to
be subject to the foregoing requirements must be approved by the affirmative
vote of at least 80% of the votes entitled to be cast by all holders of
outstanding shares of voting stock and two-thirds of the votes entitled to be
cast by holders of outstanding shares of voting stock who are not interested
stockholders. Any such amendment is not effective until 18 months after the vote
of stockholders and does not apply to any business combination of a corporation
with a stockholder who was an interested stockholder on the date of the
stockholder vote. The Company has opted out of the business combination
provisions of the MGCL, but the Board of Directors may elect to adopt these
provisions of the MGCL in the future.
 
CONTROL SHARE ACQUISITION STATUTE
 
    Maryland law imposes certain limitations on the voting rights in a "control
share acquisition." The MGCL considers a "control share acquisition" to occur at
each of the 20%, 33 1/3% and 50% acquisition levels, and requires the
affirmative vote of at least two-thirds of the votes entitled to be cast by
holders of outstanding shares of voting stock (excluding shares owned by the
acquiring person and certain members of management) to accord voting rights to
capital stock acquired in a control share acquisition. The statute also requires
Maryland corporations to hold a special meeting at the request of an actual or
proposed control share acquirer generally within 50 days after a request is made
by means of the submission of an "acquiring person statement," but only if the
acquiring person (i) posts a bond for the cost of a meeting (not including the
expenses of opposing approval of the voting rights) and (ii) submits a
definitive financing agreement with respect to the proposed control share
acquisition to the extent that financing is not provided by the acquiring
person. In addition, unless its charter or bylaws provide otherwise, the statute
gives a Maryland corporation, within certain time limitations, various
redemption rights if there is a stockholder vote on the issue and the grant of
voting rights is not approved, or if an acquiring person statement is not
delivered to the corporation within 10 days following an actual control share
acquisition.
 
                                      138
<PAGE>
Moreover, unless the charter or bylaws provide otherwise, the statute provides
that if, before a control share acquisition occurs, voting rights are accorded
to control shares that result in the acquiring persons having majority voting
power, then minority stockholders have certain appraisal rights. An acquisition
of shares may be exempted from the control share statute, provided that a
charter or bylaw provision is adopted for such purpose prior to the control
share acquisition. The Company has opted out of the control share provisions of
the MGCL, but the Board of Directors may elect to adopt these provisions of the
MGCL in the future.
 
AMENDMENTS TO THE CHARTER
 
    The Charter, including its provisions on classification of the Board of
Directors, restrictions on transferability of shares of Common Stock and removal
of directors, may be amended only by the affirmative vote of the holders of not
less than two-thirds of all of the votes entitled to be cast on the matter.
However, the provisions of the Charter relating to authorized shares of stock
and the classification and reclassification of shares of Common Stock and
Preferred Stock may be amended by the affirmative vote of the holders of not
less than a majority of the votes entitled to be cast on the matter.
 
ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS
 
    The Bylaws of the Company provide that (i) with respect to an annual meeting
of stockholders, nominations of persons for election to the Board of Directors
and the proposal of business to be considered by stockholders may be made only
(A) pursuant to the Company's notice of the meeting, (B) by the Board of
Directors or (C) by a stockholder who is entitled to vote at the meeting and has
complied with the advance notice procedures set forth in the Bylaws and (ii)
with respect to special meetings of the stockholders, only the business
specified in the Company's notice of meeting may be brought before the meeting
of stockholders and nominations of persons for election to the Board of
Directors may be made only (A) pursuant to the Company's notice of the meeting,
(B) by the Board of Directors or (C) provided that the Board of Directors has
determined that directors shall be elected at such meeting, by a stockholder who
is entitled to vote at the meeting and has complied with the advance notice
provisions set forth in the Bylaws.
 
ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS OF MARYLAND LAW AND OF THE CHARTER
  AND BYLAWS
 
    The business combination provisions and the control share acquisition
provisions of the MGCL, the provisions of the Charter on classification of the
Board of Directors and removal of directors and the advance notice provisions of
the Bylaws could delay, defer or prevent a transaction or a change in control of
the Company that might involve a premium price for holders of Common Stock or
otherwise be in their best interests.
 
RIGHTS TO PURCHASE SECURITIES AND OTHER PROPERTY
 
    The Charter authorizes the Board of Directors to create and issue rights
entitling the holders thereof to purchase from the Company shares of capital
stock or other securities or property. The times at which and terms upon which
such rights are to be issued would be determined by the Board of Directors and
set forth in the contracts or instruments that evidence such rights. This
provision is intended to confirm the Board of Directors' authority to issue
share purchase rights, which might have terms that could impede a merger, tender
offer or other takeover attempt, or other rights to purchase shares or
securities of the Company or any other corporation.
 
                        SHARES AVAILABLE FOR FUTURE SALE
 
GENERAL
 
    Upon the completion of the Offerings, the Company will have outstanding
22,292,311 shares of Common Stock (23,792,311 shares if the Underwriters'
overallotment option is exercised in full). In
 
                                      139
<PAGE>
   
addition, 2,425,169 shares of Common Stock are reserved for issuance upon
exchange of Units and 3,807,711 shares of Common Stock are reserved for issuance
via conversion of the PIERS. The shares of Common Stock issued in the Common
Offering will be freely tradeable by persons other than "affiliates" of the
Company without restriction under the Securities Act, subject to the limitations
on ownership set forth in the Charter. See "Capital Stock--Restrictions on
Transfer." The shares of Common Stock received by the participants in the
Formation Transactions or acquired by any participant in redemption of Units
(the "Restricted Shares") will be "restricted" securities under the meaning of
Rule 144 promulgated under the Securities Act ("Rule 144") and may not be sold
in the absence of registration under the Securities Act unless an exemption from
registration is available, including exemptions contained in Rule 144. As
described below under "--Registration Rights," the Company has granted certain
holders registration rights with respect to their shares of Common Stock.
    
 
    In general, under Rule 144, if one year has elapsed since the later of the
date of acquisition of Restricted Shares from the Company or any "affiliate" of
the Company, as that term is defined under the Securities Act, the acquiror or
subsequent holder thereof is entitled to sell within any three-month period a
number of shares that does not exceed the greater of 1% of the then outstanding
shares of Common Stock or the average weekly trading volume of the Common Stock
during the four calendar weeks immediately preceding the date on which notice of
the sale is filed with the Securities and Exchange Commission (the
"Commission"). Sales under Rule 144 also are subject to certain manner of sales
provisions, notice requirements and the availability of current public
information about the Company. If two years have elapsed since the date of
acquisition of Restricted Shares from the Company or from any "affiliate" of the
Company, and the acquiror or subsequent holder thereof is deemed not to have
been an affiliate of the Company at any time during the 90 days immediately
preceding a sale, such person is entitled to sell such shares in the public
market under Rule 144(k) without regard to the volume limitations, manner of
sale provisions, public information requirements or notice requirements.
 
    The Company has established a stock option plan for the purpose of
attracting and retaining highly qualified directors, executive officers and
other key employees. See "Management--Stock Option and Incentive Plan" and
"--Compensation of Directors." Since the IPO, the Company has issued options to
purchase approximately 828,000 shares of Common Stock to directors, officers and
employees and has reserved 872,000 additional shares for future issuance under
the plan. On or prior to the expiration of the initial 12-month period following
the completion of the Offering, the Company expects to file a registration
statement with the Commission with respect to the shares of Common Stock
issuable under these plans, which shares may be resold without restriction,
unless held by affiliates.
 
    No prediction can be made as to the effect, if any, that future sales of
shares, or the availability of shares for future sale, will have on the market
price prevailing from time to time. Sales of substantial amounts of Common Stock
(including shares issued upon the exercise of options), or the perception that
such sales could occur, could adversely affect prevailing market prices of the
Common Stock. See "Risk Factors--Other Risks of Ownership of Common Stock Could
Adversely Affect the Trading Price of the Common Stock" and "Partnership
Agreement--Transfers of Interests."
 
REGISTRATION RIGHTS
 
    The Company has granted the participants in the Formation Transactions who
received Units in the Formation Transactions certain registration rights with
respect to the shares of Common Stock owned by them or acquired by them in
connection with the exercise of the redemption right under the Partnership
Agreement. These registration rights require the Company to register all such
shares of Common Stock upon request. The Company will bear expenses incident to
its registration requirements under the registration rights, except that such
expenses shall not include any underwriting discounts or commissions or transfer
taxes, if any, relating to such shares.

                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
    The following discussion summarizes the material Federal income tax
consequences that are generally applicable to all prospective holders of PIERS.
The specific tax consequences of owning PIERS will vary for stockholders because
of the different circumstances of stockholders and the discussion contained
herein does not purport to address all aspects of Federal income taxation that
may be relevant to particular holders in light of their personal investment or
tax circumstances. Therefore, it is imperative that a stockholder review the
following discussion and consult with such stockholders tax advisors to
determine the interaction of such stockholders tax situation with the
anticipated tax consequences of owning PIERS.
 
    The information in this section and the opinions of Brown & Wood LLP are
based on the Code, existing and proposed Treasury Regulations thereunder,
current administrative interpretations and court decisions. No assurance can be
given that future legislation, Treasury Regulations, administrative
interpretations and court decisions will not significantly change current law or
affect existing interpretations of current law in a manner which is adverse to
stockholders. Any such change could apply retroactively to transactions
preceding the date of change. The Company and the Operating Partnership do not
plan to obtain any rulings from the IRS concerning any tax issue with respect to
the Company. Thus, no assurance can be provided that the opinions and statements
set forth herein (which do not bind the IRS or the courts) will not be
challenged by the IRS or will be sustained by a court if so challenged. The
following description does not constitute tax advice.
 
    This summary does not discuss state, local or foreign tax considerations.
Except where indicated, the discussion below describes general Federal income
tax considerations applicable to individuals who are citizens or residents of
the United States. Accordingly, the following discussion has limited application
to domestic corporations and persons subject to specialized Federal income tax
treatment, such as foreign persons, trusts, estates, tax-exempt entities,
regulated investment companies and insurance companies.
 
    As used in this section, the term "Company" refers solely to SL Green Realty
Corp. and the term "Operating Partnership" refers solely to SL Green Operating
Partnership, L.P.
 
    PROSPECTIVE STOCKHOLDERS ARE STRONGLY URGED TO CONSULT WITH THEIR OWN TAX
ADVISORS WITH REGARD TO THE APPLICATION OF THE FEDERAL INCOME TAX LAWS TO SUCH
STOCKHOLDERS' RESPECTIVE PERSONAL TAX SITUATIONS, AS WELL AS ANY TAX
CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING
JURISDICTION.
 
TAXATION OF THE COMPANY
 
    GENERAL. The Company will make an election to be taxed as a REIT under
Sections 856 through 860 of the Code effective for its taxable year ending
December 31, 1997. The Company believes that, commencing with such taxable year,
it will be organized and will operate in such a manner as to qualify for
taxation as a REIT under the Code and the Company intends to continue to operate
in such a manner. Although the Company has been structured so as to qualify to
be treated as a REIT, no assurance can be given that the Company will operate in
a manner so as to qualify or remain qualified as a REIT.
 
    In the opinion of Brown & Wood LLP, commencing with the Company's taxable
year ended December 31, 1997, the Company will be organized in conformity with
the requirements for qualification and taxation as a REIT under the Code and the
proposed method of operation of the Company will enable the Company to meet the
requirements for qualification and taxation as a REIT. This opinion is based on
various assumptions relating to the organization and operation of the Company,
the Operating Partnership, the Management LLC, the Management Corporation
(together with the Management LLC, the
 
                                      141
<PAGE>
"Management Entities"), the Leasing Corporation and the Construction Corporation
and upon certain representations made by the Company, the Operating Partnership,
the Management Entities, the Leasing Corporation and the Construction
Corporation as to certain relevant factual matters, including matters related to
the organization and expected manner of operation of the Company, the Operating
Partnership, the Property-owning entities, the Management Entities, the Leasing
Corporation and the Construction Corporation. Moreover, such qualification and
taxation as a REIT will depend upon the Company's ability to meet on a
continuing basis, through actual annual operating results, distribution levels,
and diversity of stock ownership, the various qualification tests imposed under
the Code (discussed below). Brown & Wood LLP will not review compliance with
these tests on a continuing basis. Accordingly, no assurance can be given that
the Company will satisfy such tests on a continuing basis. See "--Failure to
Qualify" below.
 
    The following is a general summary of the material Code provisions that
govern the Federal income tax treatment of a REIT and its stockholders. These
provisions of the Code are highly technical and complex.
 
    If the Company qualifies for taxation as a REIT, it generally will not be
subject to Federal corporate income taxes on net income that it distributes
currently to stockholders. This treatment substantially eliminates the "double
taxation" (taxation at both the corporate and stockholder levels) that generally
results from investment in a corporation. However, the Company will be subject
to Federal income and excise tax in certain circumstances, including the
following. First, the Company will be taxed at regular corporate rates on any
undistributed REIT taxable income, including undistributed net capital gains
(other than certain retained capital gains as discussed below). Second, under
certain circumstances, the Company may be subject to the "alternative minimum
tax" on its items of tax preference. Third, if the Company has (i) net income
from the sale or other disposition of "foreclosure property" (which is, in
general, property acquired by foreclosure or otherwise on default of a loan
secured by the property) held primarily for sale to customers in the ordinary
course of business or (ii) other non-qualifying income from foreclosure
property, the Company will be subject to tax at the highest corporate rate on
such income. Fourth, if the Company has net income from prohibited transactions
(which are, in general, certain sales or other dispositions of property (other
than dispositions of foreclosure property and, as a result of the Taxpayer
Relief Act of 1997, enacted on August 5, 1997 (the "Taxpayer Relief Act"),
effective for the Company's taxable year ending December 31, 1998, dispositions
of property that occur due to an involuntary conversion) held primarily for sale
to customers in the ordinary course of business), such income will be subject to
a 100% tax. Fifth, if the Company fails to satisfy either the 75% gross income
test or the 95% gross income test (both of which are discussed below), but
nonetheless maintains its qualification as a REIT because certain other
requirements have been met, it will be subject to a 100% tax on the greater of
the amount by which the Company fails the 75% or 95% test, multiplied by a
fraction intended to reflect the Company's profitability. Sixth, if the Company
fails to distribute during each calendar year at least the sum of (i) 85% of its
REIT ordinary income for such year, (ii) 95% of its REIT capital gain net income
for such year and (iii) any undistributed taxable income from prior years, the
Company will be subject to a 4% excise tax on the excess of such required
distribution over the amounts actually distributed. Seventh, if the Company
acquires any asset from a C corporation (i.e., a corporation generally subject
to full corporate level tax) in a transaction in which the basis of the asset in
the Company's hands is determined by reference to the basis of the asset (or any
other property) in the hands of the C corporation and the Company recognizes
gain on the disposition of such asset during the ten-year period (the
"Recognition Period") beginning on the date on which such asset was acquired by
the Company, then, to the extent of such property's "built-in" gain (the excess
of the fair market value of such property at the time of acquisition by the
Company over the adjusted basis in such property at such time), such gain will,
under Treasury Regulations to be issued in the future, be subject to tax at the
highest regular corporate rate applicable (the "Built-In Gain Rule").
 
    REQUIREMENTS FOR QUALIFICATION. The Code defines a REIT as a corporation,
trust, or association (i) that is managed by one or more trustees or directors;
(ii) the beneficial ownership of which is evidenced by transferable shares or by
transferable certificates of beneficial interest; (iii) that would be taxable as
a
 
                                      142
<PAGE>
domestic corporation, but for Section 856 through 859 of the Code; (iv) that is
neither a financial institution nor an insurance company subject to certain
provisions of the Code; (v) the beneficial ownership of which is held by 100 or
more persons; (vi) during the last half of each taxable year not more than 50%
in value of the outstanding stock of which is owned, directly or indirectly, by
five or fewer individuals (as defined in the Code to include certain entities);
and (vii) that meets certain other tests, described below, regarding the nature
of its income and assets. The Code provides that conditions (i) through (iv),
inclusive, must be met during the entire taxable year and that condition (v)
must be met during at least 335 days of a taxable year of 12 months, or during a
proportionate part of a taxable year of less than 12 months. Conditions (v) and
(vi), however, will not apply until after the first taxable year for which an
election is made to be taxed as a REIT. The Company anticipates that it will
have issued and outstanding sufficient shares of Common Stock and PIERS with
sufficient diversity of ownership to allow the Company to satisfy conditions (v)
and (vi). In addition, the Company intends to comply with Treasury Regulations
requiring it to ascertain the actual ownership of its outstanding shares. The
Taxpayer Relief Act eliminates the rule that a failure to comply with these
regulations will result in a loss of REIT status. Instead, a failure to comply
with the regulations will result in a fine. This provision will be effective for
the Company's taxable year ending December 31, 1998. In addition, the Company's
Charter will include restrictions regarding the transfer of its shares of
capital stock that are intended to assist the Company in continuing to satisfy
the share ownership requirements described in (v) and (vi) above. See "Capital
Stock--Restrictions on Transfer."
 
    In addition, a corporation may not elect to become a REIT unless its taxable
year is the calendar year. The Company's taxable year will be the calendar year.
 
    If a REIT owns a corporate subsidiary that is a "qualified REIT subsidiary,"
that subsidiary is disregarded for Federal income tax purposes and all assets,
liabilities and items of income, deduction and credit of the subsidiary are
treated as assets, liabilities and items of the REIT itself. (A qualified REIT
subsidiary is a corporation all of the capital stock of which has been owned by
the REIT from the commencement of such corporate existence. The Taxpayer Relief
Act eliminates the requirement that a REIT own a qualified REIT subsidiary from
the commencement of its corporate existence. This change will be effective for
the Company's taxable year ending December 31, 1998.) Similarly, a single member
limited liability company owned by the REIT or by the Operating Partnership is
disregarded as a separate entity for Federal income tax purposes.
 
    In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that for purposes of the gross income tests and asset tests
the REIT will be deemed to own its proportionate share (based on its interest in
partnership capital) of the assets of the partnership and will be deemed to be
entitled to the income of the partnership attributable to such share. In
addition, the assets and gross income of the partnership will retain the same
character in the hands of the REIT for purposes of Section 856 of the Code,
including satisfying the gross income tests and asset tests, that they have in
the hands of the Partnership. Thus, the Company's proportionate share of the
assets, liabilities and items of gross income of the Operating Partnership will
be treated as assets, liabilities and items of gross income of the Company for
purposes of applying the requirements described herein.
 
    INCOME TESTS. In order to maintain qualification as a REIT, three gross
income tests must be satisfied annually. First, at least 75% of the REIT's gross
income (excluding gross income from "prohibited transactions") for each taxable
year must be derived directly or indirectly from investments relating to real
property or mortgages on real property (including "rents from real property"
and, in certain circumstances, interest) or from certain types of temporary
investments. Second, at least 95% of the REIT's gross income (excluding gross
income from prohibited transactions) for each taxable year must be derived from
such real property investments described above and from dividends, interest and
gain from the sale or disposition of stock or securities, or from any
combination of the foregoing. Third, gain from the sale or other disposition of
stock or securities held for less than one year, gain from prohibited
transactions and gain on the sale or other disposition of real property held for
less than four years (apart from involuntary
 
                                      143
<PAGE>
conversions and sales of foreclosure property) must represent less than 30% of
the REIT's gross income (including gross income from prohibited transactions)
for each taxable year. For purposes of applying the 30% gross income test, the
holding period of Properties and other assets acquired in the Formation
Transactions will be deemed to have commenced on the date of the Formation
Transactions. The Taxpayer Relief Act repeals the 30% gross income test for
taxable years beginning after its enactment on August 5, 1997. Thus, the 30%
gross income test will apply only to the Company's taxable year ended December
31, 1997.
 
    Rents received by a REIT will qualify as "rents from real property" in
satisfying the gross income requirements for a REIT described above only if
several conditions are met. First, the amount of rent must not be based in whole
or in part on the income or profits of any person. However, an amount received
or accrued generally will not be excluded from the term "rents from real
property" solely by reason of being based on a fixed percentage or percentages
of receipts or sales. Second, rents received from a tenant will not qualify as
"rents from real property" in satisfying the gross income tests if the REIT, or
a direct or indirect owner of 10% or more of the REIT, directly or
constructively, owns 10% or more of such tenant (a "Related Party Tenant").
Third, if rent attributable to personal property, leased in connection with a
lease of real property, is greater than 15% of the total rent received under the
lease, then the portion of rent attributable to such personal property will not
qualify as "rents from real property." Finally, in order for rents received with
respect to a property to qualify as "rents from real property," the REIT
generally must not operate or manage the property or furnish or render services
to tenants, except through an "independent contractor" who is adequately
compensated and from whom the Company derives no income. The "independent
contractor" requirement, however, does not apply to the extent the services
provided by the REIT are "usually or customarily rendered" in connection with
the rental of space for occupancy only and are not otherwise considered
"rendered to the occupant." The Taxpayer Relief Act provides a DE MINIMIS rule
for non-customary services which is effective for taxable years beginning after
August 5, 1997. If the value of the non-customary service income with respect to
a property (valued at no less than 150% of the Company's direct costs of
performing such services) is 1% or less of the total income derived from the
property, then all rental income except the non-customary service income will
qualify as "rents from real property." This provision will be effective for the
Company's taxable year ending December 31, 1998.
 
    The Company does not anticipate charging rent that is based in whole or in
part on the income or profits of any person (except by reason of being based on
a fixed percentage or percentages of receipts of sales consistent with the rule
described above). The Company does not anticipate deriving rent attributable to
personal property leased in connection with real property that exceeds 15% of
the total rents.
 
    The Company will provide certain services with respect to the Properties,
but the Company believes (and has represented to Brown & Wood LLP) that all such
services will be considered "usually or customarily rendered" in connection with
the rental of space for occupancy only, so that the provision of such services
will not jeopardize the qualification of rent from the Properties as "rents from
real property." In rendering its opinion on the Company's ability to qualify as
a REIT, Brown & Wood LLP is relying on such representations. In the case of any
services that are not "usual and customary" under the foregoing rules, the
Company intends to employ "independent contractors" to provide such services.
 
    The Operating Partnership may receive certain types of income, including
rent from Related Party Tenants, with respect to the properties it owns that
will not qualify under the 75% or 95% gross income test. In particular,
dividends on the Operating Partnership's stock in the Service Corporations will
not qualify under the 75% gross income test. The Company believes, however, that
the aggregate amount of such items and other non-qualifying income in any
taxable year will not cause the Company to exceed the limits on non-qualifying
income under the 75% and 95% gross income tests.
 
    The Management LLC will receive managements fees from the Operating
Partnership with respect to properties that are wholly-owned by the Operating
Partnership. In the opinion of Brown & Wood LLP, such fees will not constitute
gross income of the Operating Partnership.
 
                                      144
<PAGE>
    If the Company fails to satisfy one or both of the 75% or the 95% gross
income tests for any taxable year, it nevertheless may qualify as a REIT for
such year if it is entitled to relief under certain provisions of the Code.
These relief provisions generally will be available if the Company's failure to
meet any such tests was due to reasonable cause and not due to willful neglect,
the Company attaches a schedule of the sources of its income to its Federal
corporate income tax return and any incorrect information on the schedule was
not due to fraud with intent to evade tax. It is not possible, however, to state
whether in all circumstances the Company would be entitled to the benefit of
these relief provisions. As discussed in "--General" above, even if these relief
provisions were to apply, a tax would be imposed with respect to the excess net
income. Moreover, these relief provisions would be unavailable if the Company
failed the 30% gross income test.
 
    ASSET TESTS. The Company must also satisfy three tests relating to the
nature of its assets at the close of each quarter of its taxable year. First, at
least 75% of the value of the Company's total assets must be represented by real
estate assets (including (i) its allocable share of real estate assets held by
the Operating Partnership or any partnerships in which the Operating Partnership
owns an interest and (ii) stock or debt instruments held for not more than one
year purchased with the proceeds of a stock offering or long-term (i.e., at
least five-year) public debt offering of the Company), cash, cash items and
government securities. Second, of the investments not included in the 75% asset
class, the value of any one issuer's securities owned by the Company may not
exceed 5% of the value of the Company's total assets. Third, of the investments
not included in the 75% asset class, the Company may not own more than 10% of
any one issuer's outstanding voting securities.
 
    After initially meeting the asset tests at the close of any quarter, the
Company will not lose its status as a REIT for failure to satisfy the asset
tests at the end of a later quarter solely by reason of changes in asset values.
If the failure to satisfy the asset tests results from an acquisition of
securities or other property during a quarter, the failure can be cured by
disposition of sufficient non-qualifying assets within 30 days after the close
of that quarter. The Company intends to maintain adequate records of the value
of its assets to ensure compliance with the asset tests and to take such other
action within 30 days after the close of any quarter as may be required to cure
any noncompliance.
 
    Based on the foregoing, the 5% test must generally be met for any quarter in
which the Company acquires securities of an issuer. Thus, this requirement must
be satisfied not only on the date the Company acquires securities of the Service
Corporations, but also each time the Company increases its ownership of
securities of a Service Corporation (including as a result of increasing its
interest in the Operating Partnership as limited partners exercise their
redemption rights).
 
    The Operating Partnership will own all of the non-voting stock of each of
the Service Corporations, which stock represents 95% of the equity of the
Service Corporations. See "Structure and Formation of the Company--The Operating
Entities of the Company--The Service Corporations." By virtue of its ownership
of Units, the Company will be considered to own its pro rata share of the assets
of the Operating Partnership, including the securities of the Service
Corporations described above. The Operating Partnership will not own more than
10% of the voting securities of the Service Corporations and, therefore, the
Company will not own more than 10% of the voting securities of the Service
Corporations. In addition, the Company and senior management believe that the
Company's pro rata share of the value of the securities of the Service
Corporations will not exceed, for each Service Corporation, as of the completion
of the Offering, 5% of the total value of the Company's assets. The Company's
belief is based in part upon its analysis of the anticipated operating cash
flows of the Service Corporations. There can be no assurance, however, that the
IRS will not contend that the value of the securities of a Service Corporation
exceeds the 5% value limitation. Brown & Wood LLP, in rendering its opinion
regarding the qualification of the Company as a REIT, will rely on the
conclusions of the Company and its senior management as to the value of the
securities of the Service Corporations.
 
                                      145
<PAGE>
    As noted above, the 5% value requirement must be satisfied at or within 30
days after the end of each quarter during which the Company increases its
(direct or indirect) ownership of securities of the Service Corporations
(including as a result of increasing its interest in the Operating Partnership).
Although the Company plans to take steps to ensure that it satisfies the 5%
value test for any quarter with respect to which retesting is to occur, there
can be no assurance that such steps always will be successful or will not
require a reduction in the Operating Partnership's overall interest in a Service
Corporation.
 
    Although currently the IRS will not rule regarding compliance with the 10%
voting securities test, in the opinion of Brown & Wood LLP the Company's
proposed structure will meet the current statutory requirements with respect to
the 10% voting securities test.
 
    ANNUAL DISTRIBUTION REQUIREMENTS. The Company, in order to qualify as a
REIT, is required to distribute dividends (other than capital gain dividends) to
its stockholders in an amount at least equal to (i) the sum of (A) 95% of the
Company's "REIT taxable income" (computed without regard to the dividends paid
deduction and the REIT's net capital gain) and (B) 95% of the net income (after
tax), if any, from foreclosure property, minus (ii) the sum of certain items of
noncash income (including, as a result of the Taxpayer Relief Act of 1997, INTER
ALIA cancellation of indebtedness and original issue discount income). Such
distributions must be paid during the taxable year to which they relate (or
during the following taxable year, if declared before the Company timely files
its tax return for the preceding year and paid on or before the first regular
dividend payment after such declaration). To the extent that the Company does
not distribute all of its net capital gain or distributes at least 95%, but less
than 100%, of its "REIT taxable income," as adjusted, it will be subject to tax
on the undistributed amount at regular corporate capital gains rates and
ordinary income tax rates. Furthermore, if the Company fails to distribute
during each calendar year at least the sum of (i) 85% of its REIT ordinary
income of such year, (ii) 95% of its REIT capital gain income for such year and
(iii) any undistributed taxable income from prior periods, the Company will be
subject to a 4% excise tax on the excess of such amounts over the amounts
actually distributed. In addition, if the Company disposes of any asset subject
to the Built-In Gain Rule during its Recognition Period, the Company will, under
Treasury Regulations to be issued in the future, be required to distribute at
least 95% of the built-in gain (after tax), if any, recognized on the
disposition.
 
    The Company intends to make timely distributions sufficient to satisfy the
annual distribution requirements. In this regard, it is expected that the
Company's REIT taxable income will be less than its cash flow due to the
allowance of depreciation and other noncash charges in the computing of REIT
taxable income. Moreover, the Partnership Agreement of the Operating Partnership
authorizes the Company, as general partner, to take such steps as may be
necessary to cause the Operating Partnership to make distributions to its
partners of amounts sufficient to permit the Company to meet these distribution
requirements. It is possible, however, that the Company, from time to time, may
not have sufficient cash or other liquid assets to meet the 95% distribution
requirement due to timing differences between the actual receipt of income and
actual payment of deductible expenses and the inclusion of such income and
deduction of such expenses in arriving at REIT taxable income of the Company, or
due to an excess of nondeductible expenses such as principal amortization or
capital expenditures over noncash deductions such as depreciation. In the event
that such circumstances do occur, then in order to meet the 95% distribution
requirement, the Company may cause the Operating Partnership to arrange for
short-term, or possibly long-term, borrowings to permit the payment of required
dividends.
 
    Under certain circumstances, the Company may be able to rectify a failure to
meet the distribution requirement for a year by paying "deficiency dividends" to
stockholders in a later year that may be included in the Company's deduction for
dividends paid for the earlier year. Thus, the Company may be able to avoid
being taxed on amounts distributed as deficiency dividends. However, the Company
would be required to pay to the IRS interest based upon the amount of any
deduction taken for deficiency dividends.
 
    FAILURE TO QUALIFY. If the Company fails to qualify for taxation as a REIT
in any taxable year and certain relief provisions do not apply, the Company will
be subject to tax (including any applicable alternative
 
                                      146
<PAGE>
minimum tax) on its taxable income at regular corporate rates. Unless entitled
to relief under specific statutory provisions, the Company also will be
disqualified from taxation as a REIT for the four taxable years following the
year during which qualification was lost. It is not possible to state whether in
all circumstances the Company would be entitled to such statutory relief.
 
    Distributions to stockholders in any year in which the Company fails to
qualify as a REIT will not be deductible by the Company, nor will the Company be
required to make distributions. If the Company makes distributions, such
distributions will be taxable as ordinary income to the extent of the Company's
current and accumulated earnings and profits. Subject to certain limitations in
the Code, corporate distributees may be eligible for the dividends received
deduction.
 
    RECENT DEVELOPMENTS.  On February 2, 1998, the Clinton Administration
released a summary of its proposed budget plan which contained several proposals
affecting REITs. One such proposal, if enacted in its present form, would
prohibit a REIT from holding securities representing more than 10% of the value
of all classes of stock of a corporation, other than a qualified REIT subsidiary
or another REIT. Although current stock interests in existing subsidiaries, such
as the Management Corporation, the Management LLC, the Leasing Corporation and
the Construction Corporation (together, the "Subsidiary Corporations"), would be
grandfathered under such proposal, the Subsidiary Corporations would be
prohibited from acquiring substantial new assets or engaging in a new trade or
business. If enacted in its present form, the proposal may limit the future
activities and growth of the Subsidiary Corporations. No prediction can be made
as to whether such proposal or any other proposal affecting REITs will be
enacted into legislation and the impact of any such legislation on the Company.
 
TAXATION OF STOCKHOLDERS GENERALLY
 
    Taxation of Domestic Stockholders. As long as the Company qualifies as a
REIT, distributions made to the Company's taxable domestic stockholders out of
current or accumulated earnings and profits (and not designated as capital gain
dividends) will be taken into account by them as ordinary income and corporate
stockholders will not be eligible for the dividends received deduction as to
such amounts. Distributions that are designated as capital gain dividends will
be taxed as long-term capital gains (to the extent they do not exceed the
Company's actual net capital gain for the taxable year) without regard to the
period for which the stockholder has held its stock. However, corporate
stockholders may be required to treat up to 20% of certain capital gain
dividends as ordinary income. The Taxpayer Relief Act provides that, beginning
with the Company's taxable year ending December 31, 1998, if the Company elects
to retain and pay income tax on any net long term capital gain, domestic
stockholders of the Company would include in their income as long term capital
gain their proportionate share of such net long term capital gain. A domestic
stockholder would also receive a refundable tax credit for such stockholder's
proportionate share of the tax paid by the REIT on such retained capital gains
and an increase in its basis in the stock of the REIT in an amount equal to the
difference between the undistributed long term capital gains and the amount of
tax paid by the REIT. In addition, Notice 97-64 provides temporary guidance with
respect to the taxation of distributions by the Company designated as capital
gain dividends. Pursuant to Notice 97-64, forthcoming Temporary Regulations will
provide that capital gains allocated to a stockholder by the Company may be
designated as a 20% rate gain distribution, an unrecaptured Section 1250 gain
distribution (subject to a 25% rate), or a 28% rate gain distribution. In
determining the amounts which may be designated as each class of capital gains
dividends, a REIT must calculate its net capital gains as if it were an
individual subject to a marginal tax rate of 28%. Unless specifically designated
otherwise by the Company, a distribution designated as a capital gain
distribution is presumed to be a 28% rate gain distribution. If the Company
elects to retain any net long-term capital gain, as discussed above, the
undistributed long-term capital gains are considered to be designated as capital
gain dividends for purposes of Notice 97-64. Distributions in excess of current
and accumulated earnings and profits will not be taxable to a stockholder to the
extent that they do not exceed the adjusted basis of the stockholder's shares of
Common Stock, but rather will reduce the adjusted basis of a stockholder's
shares of Common
 
                                      147
<PAGE>
Stock. To the extent that such distributions exceed the stockholder's adjusted
basis in his shares of Common Stock, they will be included in income as
long-term capital gain (or short-term capital gain if the shares have been held
for one year or less), assuming the shares of Common Stock are a capital asset
in the hands of the stockholder.
 
    Any dividend declared by the Company in October, November or December of any
year payable to a stockholder of record on a specific date in any such month
shall be treated as both paid by the Company and received by the stockholder on
December 31 of such year, if the dividend is actually paid by the Company during
January of the following calendar year.
 
    Stockholders may not include in their individual income tax returns net
operating losses or capital losses of the Company. In addition, distributions
from the Company and gain from the disposition of PIERS will not be treated as
"passive activity" income and, therefore, stockholders will not be able to use
passive losses to offset such income.
 
    In general, a domestic stockholder will realize capital gain or loss on the
disposition of PIERS equal to the difference between (i) the amount of cash and
the fair market value of any property received on such disposition, and (ii) the
stockholder's adjusted basis of such PIERS. Such gain or loss generally will
constitute short-term capital gain or loss if the stockholder has not held such
shares for more than one year, and long-term capital gain or loss if the
stockholder has held such shares for more than one year. The maximum rate of tax
on net capital gains of individuals, trusts and estates from the sale or
exchange of PIERS held for more than 18 months is 20%, and the maximum rate is
reduced to 18% for assets acquired after December 31, 2000 and held for more
than five years. For individuals, trusts and estates who would be subject to a
maximum tax rate of 15%, the rate on net capital gains is reduced to 10%, and
effective for taxable years commencing after December 31, 2000, the rate is
reduced to 8% for assets held for more than five years. The maximum rate for net
capital gains attributable to the sale of depreciable real property held for
more than 18 months is 25% to the extent of the deductions for depreciation
(other than certain depreciation recapture taxable as ordinary income) with
respect to such property. The maximum rate of capital gains tax for capital
assets held more than one year but not more than 18 months remains at 28%. In
general, any loss upon a sale or exchange of PIERS by a stockholder which has
held such PIERS for six months or less (after applying certain holding period
rules) will be treated as a long-term capital loss to the extent of
distributions from the Company required to be treated by such stockholder as
long-term capital gains.
 
    BACKUP WITHHOLDING. The Company will report to its domestic stockholders and
the IRS the amount of dividends paid during each calendar year and the amount of
tax withheld, if any, with respect thereto. Under the backup withholding rules,
a stockholder may be subject to backup withholding at the rate of 31% with
respect to dividends paid unless such holder (i) is a corporation or comes
within certain other exempt categories and, when required, demonstrates this
fact, or (ii) provides a taxpayer identification number and certifies as to no
loss of exemption, and otherwise complies with the applicable requirements of
the backup withholdings rules. Any amount paid as backup withholding will be
creditable against the stockholder's income tax liability. The United States
Treasury has recently issued final regulations (the "Final Regulations")
regarding the withholding and information reporting rules discussed above. In
general, the Final Regulations do not alter the substantive withholding and
information reporting requirements but unify current certification procedures
and forms and clarify and modify reliance standards. The Final Regulations
generally are effective for payments made on or after January, 2000, subject to
certain transition rules.
 
    In addition, the Company may be required to withhold a portion of capital
gain distributions made to any stockholders which fail to certify their non
foreign status to the Company. See "--Taxation of Foreign Stockholders" below.
 
    TAXATION OF TAX-EXEMPT STOCKHOLDERS. The IRS has ruled that amounts
distributed as dividends by a qualified REIT generally do not constitute
unrelated business taxable income ("UBTI") when received by
 
                                      148
<PAGE>
a tax-exempt entity. Based on that ruling, the dividend income from the PIERS
will not be UBTI to a tax-exempt stockholder, provided that the tax-exempt
stockholder has not held its PIERS as "debt financed property" within the
meaning of the Code and such shares are not otherwise used in a trade or
business. Similarly, income from the sale of PIERS will not constitute UBTI
unless such tax-exempt stockholder has held such shares as "debt financed
property" within the meaning of the Code or has used the shares in a trade or
business.
 
    Notwithstanding the above, however, a portion of the dividends paid by a
"pension held REIT" will be treated as UBTI as to any trust which is described
in Section 401(a) of the Code and is tax-exempt under Section 501(a) of the Code
(a "qualified trust") and which holds more than 10% (by value) of the interests
in the REIT. A REIT is a "pension held REIT" if (i) it would not have qualified
as a REIT but for the application of a "look-through" exception to the "not
closely held" requirement applicable to qualified trusts, and (ii) either (A) at
least one such qualified trust holds more than 25% (by value) of the interests
in the REIT, or (B) one or more such qualified trusts, each of which owns more
than 10% (by value) of the interests in the REIT, hold in the aggregate more
than 50% (by value) of the interests in the REIT. The percentage of any REIT
dividend treated as UBTI is equal to the ratio of (i) the gross income (less
direct expenses related thereto) of the REIT from unrelated trades or businesses
(determined as if the REIT were a qualified trust) to (ii) the total gross
income (less direct expenses related thereto) of the REIT. A DE MINIMIS
exception applies where this percentage is less than 5% for any year. The
provisions requiring qualified trusts to treat a portion of REIT distributions
as UBTI will not apply if the REIT is able to satisfy the "not closely held"
requirement without relying upon the "look-through" exception with respect to
qualified trusts. As a result of certain limitations on transfer and ownership
of Common Stock contained in the Charter, the Company does not expect to be
classified as a "pension held REIT."
 
    TAXATION OF NON-U.S. STOCKHOLDERS. The rules governing U.S. Federal income
taxation of nonresident alien individuals, foreign corporations, foreign
partnerships and other foreign stockholders (collectively, "Non-U.S.
Stockholders") are complex and no attempt will be made herein to provide more
than a limited summary of such rules. Prospective Non-U.S. Stockholders should
consult with their own tax advisors to determine the impact of U.S. Federal,
state and local income tax laws with regard to an investment in shares of Common
Stock, including any reporting requirements.
 
    ORDINARY DIVIDENDS. Distributions, other than distributions that are treated
as attributable to gain from sales or exchanges by the Company of U.S. real
property interests (discussed below) and other than distributions designated by
the Company as capital gain dividends, will be treated as ordinary income to the
extent that they are made out of current or accumulated earnings and profits of
the Company. Such distributions to foreign stockholders will ordinarily be
subject to a withholding tax equal to 30% of the gross amount of the
distribution, unless an applicable tax treaty reduces that tax rate. However, if
income from the investment in the shares of Common Stock is treated as
effectively connected with the Non-U.S. Stockholder's conduct of a U.S. trade or
business, the Non-U.S. Stockholder generally will be subject to a tax at
graduated rates in the same manner as U.S. stockholders are taxed with respect
to such dividends (and may also be subject to the 30% branch profits tax if the
stockholder is a foreign corporation). The Company expects to withhold U.S.
income tax at the rate of 30% on the gross amount of any dividends, other than
dividends treated as attributable to gain from sales or exchanges of U.S. real
property interests and capital gain dividends, paid to a Non-U.S. Stockholder,
unless (i) a lower treaty rate applies and the required form evidencing
eligibility for that reduced rate is filed with the Company or (ii) the Non-U.S.
Stockholder files an IRS Form 4224 (or its future equivalent) with the Company
claiming that the distributions are "effectively connected" income.
 
    Pursuant to the Final Regulations generally effective for payments made on
or after January 1, 2000, dividends paid to an address in a country outside the
United States will no longer be presumed to be paid to a resident of such
country for purposes of determining the applicability of withholding discussed
above and the applicability of a tax treaty rate. A Non-U.S. Stockholder who
wishes to claim the benefit of an applicable treaty rate will now required to
satisfy certain certification and other requirements.
 
                                      149
<PAGE>
    RETURN OF CAPITAL. Distributions in excess of current and accumulated
earnings and profits of the Company, which are not treated as attributable to
the gain from disposition by the Company of a U.S. real property interest, will
not be taxable to a Non-U.S. Stockholder to the extent that they do not exceed
the adjusted basis of the Non-U.S. Stockholder's shares of Common Stock, but
rather will reduce the adjusted basis of such shares of Common Stock. To the
extent that such distributions exceed the adjusted basis of a Non-U.S.
Stockholder's shares of Common Stock, they will give rise to tax liability if
the Non-U.S. Stockholder otherwise would be subject to tax on any gain from the
sale or disposition of its shares of Common Stock, as described below. If it
cannot be determined at the time a distribution is made whether such
distribution will be in excess of current and accumulated earnings and profits,
the distribution will be subject to withholding at the rate applicable to
dividends. However, the Non-U.S. Stockholder may seek a refund of such amounts
from the IRS if it is subsequently determined that such distribution was, in
fact, in excess of current and accumulated earnings and profits of the Company.
 
    CAPITAL GAIN DIVIDENDS. For any year in which the Company qualifies as a
REIT, distributions that are attributable to gain from sales or exchanges by the
Company of U.S. real property interests will be taxed to a Non-U.S. Stockholder
under the provisions of the Foreign Investment in Real Property Tax Act of 1980,
as amended ("FIRPTA"). Under FIRPTA, these distributions are taxed to a Non-U.S.
Stockholder as if such gain were effectively connected with a U.S. business.
Thus, Non-U.S. Stockholders will be taxed on such distributions at the same
capital gain rates applicable to U.S. stockholders (subject to any applicable
alternative minimum tax and special alternative minimum tax in the case of
nonresident alien individuals), without regard to whether such distributions are
designated by the Company as capital gain dividends. Also, distributions subject
to FIRPTA may be subject to a 30% branch profits tax in the hands of a corporate
Non-U.S. Stockholder not entitled to treaty relief or exemption. The Company is
required by applicable Treasury Regulations under FIRPTA to withhold 35% of any
distribution that could be designated by the Company as a capital gain dividend.
 
    PIERS SALES. Gain recognized by a Non-U.S. Stockholder upon a sale or
exchange of PIERS, including a redemption that is treated as a sale, generally
will not be taxed under FIRPTA if the Company is a "domestically controlled
REIT," defined generally as a REIT in respect of which at all times during a
specified testing period less than 50% in value of the stock was held directly
or indirectly by foreign persons. It is currently anticipated that the Company
will be a "domestically controlled REIT" and that therefore the sale of shares
of Common Stock will not be subject to taxation under FIRPTA. However, gain not
subject to FIRPTA will be taxable to a Non-U.S. Stockholder if (i) investment in
the shares of Common Stock is treated as "effectively connected" with the
Non-U.S. Stockholder's U.S. trade or business, in which case the Non-U.S.
Stockholder will be subject to the same treatment as U.S. stockholders with
respect to such gain, or (ii) the Non U.S. Stockholder is a nonresident alien
individual who was present in the United States for 183 days or more during the
taxable year and has a "tax home" in the United States, or maintains an office
or a fixed place of business in the United States to which the gain is
attributable, in which case the nonresident alien individual will be subject to
a 30% tax on the individual's capital gains. A similar rule will apply to
capital gain dividends not subject to FIRPTA.
 
    Although the Company anticipates that it will qualify as a domestically
controlled REIT, because the PIERS will be publicly traded, no assurance can be
given that the Company will continue to so qualify. If the Company were not a
domestically controlled REIT, whether or not a Non-U.S. Stockholder's sale of
PIERS would be subject to tax under FIRPTA would depend on whether or not the
PIERS were regularly traded on an established securities market and on the size
of the selling Non-U.S. Stockholder's interest in the Company. If the gain on
the sale of PIERS were to be subject to tax under FIRPTA, the Non-U.S.
Stockholder would be subject to the same treatment as U.S. stockholders with
respect to such gain (subject to any applicable alternative minimum tax and a
special alternative minimum tax in the case of nonresident alien individuals)
and the purchaser of such PIERS may be required to withhold 10% of the gross
purchase price.

    The Final Regulations, issued by the United States Treasury on October 6,
1997, affect the rules applicable to payments to foreign persons. In general,
the Final Regulations do not alter the substantive withholding and information
reporting requirements but unify current certification procedures and modify
reliance standards. In addition, the Final Regulations also address certain
issues relating to intermediary certification procedures designed to simplify
compliance by withholding agents. The Final Regulations are generally effective
for payments made on or after January 1, 2000, subject to certain transition
rules. Prospective investors should consult their own tax advisors concerning
the adoption of the Final Regulations and the potential effect on their
ownership of PIERS.
 
TAXATION OF HOLDERS OF PIERS
 
    DIVIDENDS AND OTHER DISTRIBUTIONS; BACKUP WITHHOLDING.  For a discussion of
the taxation of the Company, the treatment of dividends and other distributions
with respect to shares of the Company, and the backup withholding rules, see the
discussions under the captions "Material Federal Income Tax Considerations --
Taxation of the Company -- General" and "Taxation of Stockholders Generally." In
determining the extent to which a distribution on the PIERS constitutes a
dividend for tax purposes, the earnings and profits of the Company will be
allocated first to distributions with respect to the PIERS, and second to
distributions with respect to the Company's Common Stock.
 
    TAX CONSEQUENCES UPON CONVERSION OF PIERS INTO COMMON STOCK AT THE PREFERRED
HOLDER'S OPTION AND REDEMPTION OF PIERS FOR COMMON STOCK AT THE OPTION OF THE
COMPANY.  Generally, except with respect to cash received in lieu of fractional
shares, and except in the case of foreign holders of the PIERS under the
circumstances described above (see "-- Taxation of Non-U.S. Stockholders"), no
gain or loss will be recognized upon the conversion of PIERS into Common Stock
or upon the redemption of PIERS for Common Stock at the option of the Company.
The tax basis of a holder of PIERS (a "Preferred Holder") in the Common Stock
received will equal such Preferred Holder's tax basis in the PIERS surrendered
in the conversion, reduced by any cash received in lieu of fractional shares,
and the holding period for the Common Stock received will include the Preferred
Holder's holding period for the PIERS exchanged therefor. Based on the IRS's
present advance ruling policy, cash received in lieu of a fractional share of
Common Stock upon conversion of PIERS should be treated as a payment in
redemption of the fractional interest in such share of Common Stock. See "--
Redemption of PIERS for Cash" below.
 
    DEEMED DIVIDENDS ON PIERS.  The Conversion Price of the PIERS may be
adjusted if the Company makes certain distributions of stock, cash or other
property with respect to its Common Stock. While the Company does not presently
contemplate making such a distribution, if the Company does make a distribution
of cash or other property that results in an adjustment to the Conversion Price,
a Preferred Holder may be viewed as having received a "deemed distribution" that
is taxable as a dividend under Sections 301 and 305 of the Code. See "--Taxation
of Stockholders Generally."
 
    REDEMPTION OF PIERS FOR CASH.  The treatment accorded to any redemption by
the Company for cash (as distinguished from a sale, exchange or other
disposition) of PIERS can only be determined on the basis of particular facts
applicable to each Preferred Holder at the time of redemption. (For a discussion
of the treatment of a redemption of PIERS for Common Stock, see "-- Tax
Consequences Upon Conversion of PIERS into Common Stock at the Preferred
Holder's Option and Redemption of PIERS for Common Stock at the Option of the
Company" above.) In general, a Preferred Holder will recognize ordinary income
to the extent of accrued but unpaid dividends and will recognize capital gain or
loss measured by the difference between the amount received (less the amount
attributable to accrued but unpaid dividends) by the Preferred Holder upon the
redemption and such holder's adjusted tax basis in the PIERS redeemed (provided
the PIERS are held as a capital asset) if such redemption (i) results in a
"complete termination" of the Preferred Holder's interest in all classes of
stock of the Company under Section 302(b) (3) of the Code or (ii) is "not
essentially equivalent to a dividend" with respect to the Preferred Holder
within the meaning of Section 302(b) (1) of the Code. In applying these tests,
there must be taken into account not
 
                                      151
<PAGE>
only any PIERS owned by the Preferred Holder, but also such Preferred Holder's
ownership of Common Stock, and any options (including stock purchase rights) to
acquire any of the foregoing. The Preferred Holder also must take into account
any such securities (including options) which are considered to be owned by such
Preferred Holder by reason of the constructive ownership rules set forth in
Sections 318 and 302(c) of the Code.
 
    If a Preferred Holder owns (actually or constructively) no Common Stock or
an insubstantial percentage of the outstanding Common Stock, based upon current
law, it is probable that a redemption of PIERS from a Preferred Holder would be
considered "not essentially equivalent to a dividend." However, whether a
distribution is "not essentially equivalent to a dividend" depends on all of the
facts and circumstances and a Preferred Holder intending to rely on any of these
tests at the time of redemption should consult its own tax adviser to determine
their application to its particular situation.
 
    If the redemption does not meet any of the tests under Section 302 of the
Code, then the redemption proceeds received from the PIERS will be treated as a
distribution on the PIERS as described under "Material Federal Income Tax
Considerations -- Taxation of Shareholders Generally." If the redemption is
taxed as a dividend, the Preferred Holder's adjusted tax basis in the PIERS
redeemed will be transferred to any other stockholdings of the Preferred Holder
in the Company. If the Preferred Holder owns no other stock of the Company,
under certain circumstances, such basis may be transferred to a related person,
or it may be lost entirely.
 
    REDEMPTION PREMIUM.  The PIERS are redeemable at the Company's option on or
after July 15, 2003 at an amount greater than the issue price of the PIERS. The
difference between the issue price and the optional redemption amount is the
"redemption premium." (For a detailed description of the Company's option to
redeem the PIERS, see "Capital Stock--PIERS--Redemption.") Under Section 305 of
the Code and the applicable Treasury Regulations, if the redemption price of the
PIERS exceeds its issue price by more than a DE MINIMIS amount or is not solely
in the nature of a penalty for a premature redemption, the amount of such excess
may be deemed to be a constructive distribution (treated as a dividend to the
extent of the Company's current and accumulated earnings and profits) taxable to
the Preferred Holder over the period during which the PIERS cannot be redeemed
(as if it were original issue discount on a debt instrument) (the "Economic
Accrual Rule").
 
    A redemption premium is considered DE MINIMIS if it is less than the product
of 0.25% multiplied by the number of years until redemption, multiplied by the
issue price of the PIERS. A redemption premium is considered to be a penalty for
premature redemption only if it is paid as a result of changes in economic or
market conditions over which the Company or the Preferred Holder does not have
legal or practical control. Even if the redemption premium is greater than a DE
MINIMIS amount, a Preferred Holder will not have to take the redemption premium
into income pursuant to the Economic Accrual Rule unless the PIERS are (i)
mandatorily redeemable, (ii) redeemable at the Preferred Holder's option, or
(iii) redeemable at the Company's option and, at the time of issue, based on all
of the facts and circumstances, it is more likely than not that the Company will
exercise such option.
 
    The Company believes that a Preferred Holder will not have to take the
redemption premium on the PIERS into income pursuant to the Economic Accrual
Rule because (i) based on all of the facts and circumstances, at the time of
issue, the Company believes that it is not more likely than not that the Company
will redeem the PIERS at the time when the redemption premium is greater than a
DE MINIMIS amount and (ii) at the time that the PIERS are mandatorily
redeemable, the Company believes that the redemption premium will be zero.
Moreover, the Treasury Regulations provide a "safe harbor" under which a
redemption pursuant to an issuer's right to redeem is not treated as more likely
than not to occur if (i) the issuer and the holder are not related, (ii) there
are no plans, arrangements, or agreements that effectively require or are
intended to compel the issuer to redeem the stock, and (iii) exercise of the
right to redeem would not reduce the yield of the stock. The Company believes
that the PIERS will qualify for this safe harbor.

<PAGE>
OTHER TAX CONSIDERATIONS
 
    EFFECT OF TAX STATUS OF OPERATING PARTNERSHIP AND OTHER ENTITIES ON REIT
QUALIFICATION. All of the Company's significant investments are held through the
Operating Partnership. The Operating Partnership may hold interests in certain
Properties through Property-owning entities. The Operating Partnership and the
Property-owning entities, as well as the Management LLC, involve special tax
considerations. These tax considerations include: (i) allocations of income and
expense items of the Operating Partnership and the Property-owning entities,
which could affect the computation of taxable income of the Company, (ii) the
status of the Operating Partnership, the Property-owning entities and the
Management LLC as partnerships or entities that are disregarded as entities
separate from their owners (as opposed to associations taxable as corporations)
for income tax purposes and (iii) the taking of actions by the Operating
Partnership or any of the Property-owning entities that could adversely affect
the Company's qualification as a REIT.
 
    In the opinion of Brown & Wood LLP, based on certain representations of the
Company and the Operating Partnership, for Federal income tax purposes, the
Operating Partnership will be treated as a partnership and neither the
Management LLC nor any of the Property-owning entities will be treated as an
association taxable as a corporation. If, however, the Operating Partnership or
any of such other entities were treated as an association taxable as a
corporation, the Company would fail to qualify as a REIT for a number of
reasons.
 
    The Partnership Agreement requires that the Operating Partnership be
operated in a manner that will enable the Company to satisfy the requirements
for classification as a REIT. In this regard, the Company will control the
operation of the Operating Partnership through its rights as the sole general
partner of the Operating Partnership.
 
    TAX ALLOCATIONS WITH RESPECT TO THE PROPERTIES. When property is contributed
to a partnership in exchange for an interest in the partnership, the partnership
generally takes a carryover basis in that property for tax purposes (i.e., the
partnership's basis is equal to the adjusted basis of the contributing partner
in the property), rather than a basis equal to the fair market value of the
property at the time of contribution. Pursuant to Section 704(c) of the Code,
income, gain, loss and deductions attributable to such contributed property must
be allocated in a manner such that the contributing partner is charged with, or
benefits from, respectively, the unrealized gain or unrealized loss associated
with the property at the time of the contribution. The amount of such unrealized
gain or unrealized loss is generally equal to the difference between the fair
market value of the contributed property at the time of contribution and the
adjusted tax basis of such property at the time of contribution (a "Book-Tax
Difference"). Such allocations are solely for Federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the partners. The Operating Partnership was funded by way of contributions
of appreciated property to the Operating Partnership in the Formation
Transactions. Consequently, the Operating Partnership Agreement will require
such allocations to be made in a manner consistent with Section 704(c) of the
Code and the regulations thereunder (the "Section 704(c) Regulations").
 
    The Section 704(c) Regulations require partnerships to use a "reasonable
method" for allocation of items affected by Section 704(c) of the Code and
outline three methods which may be considered reasonable for these purposes. The
Operating Partnership intends to use the "traditional method" of Section 704(c)
allocations, which is the least favorable method from the Company's perspective
because of certain technical limitations. Under the traditional method,
depreciation with respect to a contributed Property for which there is a
Book-Tax Difference first will be allocated to the Company and other partners
who did not have an interest in such Property until they have been allocated an
amount of depreciation equal to what they would have been allocated if the
Operating Partnership had purchased such property for its fair market value at
the time of contribution. In addition, if such a Property is sold, gain equal to
the Book-Tax Difference at the time of sale will be specially allocated to the
contributor of the Property. These
 
                                      153
<PAGE>
allocations will tend to eliminate the Book-Tax Differences with respect to the
contributed Properties over the life of the Operating Partnership. However, they
may not always entirely eliminate the Book-Tax Difference on an annual basis or
with respect to a specific taxable transaction such as a sale. This could cause
the Company (i) to be allocated lower amounts of depreciation deduction for tax
purposes than would be allocated to the Company if all Properties were to have a
tax basis equal to their fair market value at the time of contribution and (ii)
to be allocated lower amounts of taxable loss in the event of a sale of such
contributed interests in the Properties at a book loss, than the economic or
book loss allocated to the Company as a result of such sale, with a
corresponding benefit to the other partners in the Operating Partnership. These
allocations possibly might adversely affect the Company's ability to comply with
REIT distribution requirements, although the Company does not anticipate that
this will occur. These allocations may also affect the earnings and profits of
the Company for purposes of determining the portion of distributions taxable as
a dividend income. See "--Taxation of U.S. Stockholders." The application of
these rules over time may result in a higher portion of distributions being
taxed as dividends than would have occurred had the Company purchased its
interests in the Properties at their agreed values.
 
    Interests in the Properties purchased by the Operating Partnership for cash
simultaneously with or subsequent to the admission of the Company to the
Operating Partnership initially will have a tax basis equal to their fair market
value. Thus, Section 704(c) of the Code will not apply to such interests.
 
    SERVICE CORPORATIONS. A portion of the amounts to be used by the Operating
Partnership to fund distributions to stockholders is expected to come from the
Service Corporations, through dividends on non-voting stock of the Service
Corporations to be held by the Operating Partnership. The Service Corporations
will not qualify as REITs and thus will pay Federal, state and local income
taxes on their net income at normal corporate rates. To the extent that the
Service Corporations are required to pay Federal, state and local income taxes,
the cash available for distribution to the Company's stockholders will be
reduced accordingly.
 
    As described above, the value of the securities of any Service Corporation
held by the Operating Partnership cannot exceed 5% of the value of the Operating
Partnership's assets at a time when the Company is considered to acquire
additional securities of the Service Corporation. See "--Taxation of the
Company--Asset Tests." This limitation may restrict the ability of the Service
Corporations to increase the sizes of their businesses unless the value of the

    The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase PIERS are subject to certain conditions, and that if
any of the PIERS are purchased by the Underwriters pursuant to the Underwriting
Agreement, all of the PIERS agreed to be purchased by the Underwriters under the
Underwriting Agreement must be so purchased.
 
    The Company has been advised that the Underwriters propose to offer the
PIERS directly to the public at the initial public offering price set forth on
the cover page of this Prospectus, and to certain selected dealers who may
include the Underwriters at such public offering price less a selling concession
not in excess of $   per PIERS. The selected dealers may reallow a concession
not in excess of $   per PIERS to certain brokers or dealers. After the PIERS
Offering, the public offering price, the concession to selected dealers and the
reallowance may be changed by the Representatives.
 
    The Company has granted to the Underwriters an option to purchase up to an
additional 600,000 PIERS at the public offering price less the aggregate
underwriting discounts and commissions shown on the cover page of this
Prospectus, solely to cover overallotments, if any. Such option may be exercised
at any time within 30 days after the date of the Underwriting Agreement. To the
extent that such option is exercised, each Underwriter will be committed,
subject to certain conditions, to purchase a number of additional PIERS
proportionate to such Underwriter's initial commitment as indicated in the
preceding table.
 
    The Company has agreed that it will not, without the prior written consent
of Lehman Brothers, on behalf of the Underwriters, offer for sale, contract to
sell, sell or otherwise dispose of (or enter into any transaction or device
which is designed to, or could be expected to, result in the disposition by any
person at any time in the future of), directly or indirectly, any shares of
Common Stock or securities convertible into or exercisable or exchangeable for
Common Stock (other than shares offered hereby, shares issued pursuant to the
Stock Option Plan and any Units or shares of Common Stock that may be issued in
connection with any acquisition of a property), or sell or grant options, rights
or warrants with respect to any shares of Common Stock (other than the grant of
options pursuant to the Stock Option Plan), for a period of 180 days after the
date of this Prospectus.
 
    In connection with the IPO, certain SL Green entities and certain officers
of the Company agreed that they would not, without the prior written consent of
the Company and Lehman Brothers, subject to certain exceptions, offer for sale,
contract to sell, sell or otherwise dispose of (or enter into any transaction or
device which is designed to, or could be expected to, result in the disposition
by any person at any time in the future of), directly or indirectly, any shares
of Common Stock or Units received by them in connection with the Formation
Transactions or the IPO, for an initial period of one year after the date of the
IPO prospectus, after which time one-third of such Common Stock or Units held by
each such entity or person shall no longer be subject to such restrictions and
an additional one-third thereof shall be released from such restrictions on each
of the second and third anniversaries of the date of the IPO prospectus.

    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to the payments they may be required to make in respect
thereto.
 
    Application will be made to list the PIERS and the Common Stock issuable
upon conversion or redemption of the PIERS on the NYSE. The PIERS will be listed
under the symbol "SLGPrA" and the Common Stock will be listed under the symbol
"SLG." Trading of the PIERS is expected to commence on the NYSE within 30 days
from the closing of the PIERS Offering.
 
    Until the distribution of the PIERS is completed, rules of the Commission
may limit the ability of the Underwriters to bid for and purchase the PIERS. As
an exception to these rules, the Underwriters are permitted to engage in certain
transactions that stabilize the price of the PIERS. Such transactions consist of
bids or purchases for the purpose of pegging, fixing or maintaining the price of
the PIERS.
 
    If the Underwriters create a short position in the PIERS in connection with
the offering, I.E., if they sell more shares of PIERS than are set forth on the
cover page of this Prospectus, the Underwriters may reduce that short position
by purchasing PIERS in the open market. The Underwriters may also elect to
reduce any short position by exercising all or part of the over-allotment option
described herein.
 
    The Underwriters may also impose a penalty bid on certain Underwriters. This
means that if the Underwriters purchase PIERS in the open market to reduce the
Underwriters' short position or to stabilize the price of the PIERS, they may
reclaim the amount of the selling concession from the Underwriters who sold
those shares as part of the PIERS Offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security by purchasers in an offering.
 
    Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the PIERS. In addition, neither the
Company nor any of the Underwriters makes any representation that the
Representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
    Concurrent with the PIERS Offering, the Company is offering 10,000,000
shares of Common Stock by a separate prospectus. The consummation of the PIERS
Offering is not contingent upon the consummation of the Common Offering or vice
versa. Certain of the Underwriters and their affiliates have from time to time
performed, and may continue to perform in the future, various investment banking
and other services for the Company, for which customary compensation has been,
and will be, received. In connection with the Offerings, an affiliate of Lehman
Brothers Inc. will receive $240 million of the net proceeds in repayment of
amounts outstanding under the Acquisition Facility. See "Use of Proceeds,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resource," and "The Properties--Credit
Facilities."
 
    Although the Conduct Rules of the National Association of Securities Dealers
Inc., exempt REITs from the conflict of the interest provisions thereof, because
Lehman Brothers and certain of its affiliates will receive more than 10% of the
net proceeds of the Offerings in payment of the Acquisition Facility, the
Underwriters have determined to conduct the Offering in accordance with the
applicable provisions of Rule 2720 of the Conduct Rules. In accordance with
these requirements, Prudential Securities Incorporated (the "Qualified
Independent Underwriter") is assuming the responsibilities of acting as
"qualified independent underwriter," and will recommend the maximum price to the
public for the Common Stock and the pricing terms contained herein for the PIERS
in compliance with the requirements of the Conduct Rules. In connection with the
Offerings, the Qualified Independent Underwriter is performing due diligence
investigations and is reviewing and participating in the preparation of these
Prospectuses and the
 
                                      156
<PAGE>
Registration Statements of which these Prospectuses form a part. The public
offering price of the Common Stock and the pricing terms for the PIERS will be
no higher than the price recommended by the Qualified Independent Underwriter.

1. ORGANIZATION AND BASIS OF PRESENTATION
 
INITIAL PUBLIC OFFERING AND FORMATION TRANSACTIONS
 
    SL Green Realty Corp. (the "Company"), a Maryland corporation, and SL Green
Operating Partnership, L.P., (the "Operating Partnership"), were formed in June
1997 for the purpose of combining the commercial real estate business of S.L.
Green Properties, Inc. and its affiliated partnerships and entities ("SL
Green"). The Operating Partnership received a contribution of interest in the
real estate properties as well as 95% of the economic interest in the
management, leasing and construction companies (the "Service Corporations"). The
Company qualifies as a real estate investment trust ("REIT") under the Internal
Revenue Code of 1986, as amended; and operates as a fully integrated,
self-administered, self-managed REIT. A REIT is a legal entity that holds real
estate interests and, through payments of dividends to shareholders, is
permitted to reduce or avoid the payment of federal income taxes at the
corporate level.
 
    The authorized capital stock of the Company consists of 200 million shares
of capital stock, $.01 par value, of which the Company has authorized the
issuance of up to 100 million shares of Common Stock, $.01 par value per share,
75 million shares of Excess Stock, at $.01 par value per share, and 25 million
shares of Preferred Stock, par value $.01 per share. On August 20, 1997, the
Company issued 11.615 million shares of its Common Stock (including the
underwriters' over-allotment option of 1.52 million shares) to the public
through a public offering (the "Offering"). Concurrently with the consummation
of the Offering, the Company issued 38,095 shares of restricted common stock
pursuant to stock loans and 85,600 shares of restricted common stock to a
financial advisor. In addition, the Company previously issued to its executive
officers approximately 553,616 shares, as founders' shares. As of December 31,
1997, no shares of Excess Stock or Preferred Stock are issued and outstanding.
 
    Concurrent with the consummation of the Offering, the Company and the
Operating Partnership, together with the partners and members of the affiliated
partnerships of the SL Green Predecessor and other parties which held ownership
interests in the properties contributed to the Operating Partnership
(collectively, the "Participants"), engaged in certain Formation Transactions
(the "Formation Transactions").
 
    The net cash proceeds received by the Company from the Offering (after
deducting underwriting discounts) was $228.7 million. The Company utilized
approximately $42.6 million of the Offering proceeds to repay mortgage
indebtedness encumbering the properties, including $1.5 million for prepayment
penalties and other financing fees and expenses, approximately $6.6 million to
purchase the direct or indirect interests of certain participants in the
properties, approximately $95.5 million to acquire properties (50 West 23rd
Street, 1140 Avenue of the Americas, and 1372 Broadway) approximately $3.4
million to pay certain expenses incurred in the Formation Transactions, $35.6
million to repay a loan from Lehman Brothers Holdings, Inc. ("LBHI") (which
included $20 million to repay a loan that was made to a company indirectly owned
by Stephen L. Green), $1.8 million to fund the advisory fee payment to Lehman
Brothers, Inc. and $41.7 million to fund capital expenditures, general working
capital needs and future acquisitions (See note 2).
 
    Substantially all of the Company's assets are held by, and it conducts its
operations through, the Operating Partnership, a Delaware limited partnership.
The Company is the sole managing general partner of the Operating Partnership.
Continuing investors hold, in the aggregate, a 16.2% limited partnership
interest in the Operating Partnership.

1. ORGANIZATION AND BASIS OF PRESENTATION (CONTINUED)
PRINCIPLES OF COMBINATION--SL GREEN PREDECESSOR
 
    The SL Green Predecessor is not a legal entity but rather a combination of
real estate properties and affiliated real estate management, construction and
leasing entities under common control and management of Stephen L. Green; and
interests owned and managed by Stephen L. Green in entities accounted for on the
equity method (see note 2) that are organized as partnerships and a limited
liability company. The entities included in this financial statement have been
combined for only the periods that they were under common control and
management. All significant intercompany transactions and balances have been
eliminated in combination. Capital contributions, distributions and profits and
losses are allocated in accordance with the terms of the applicable agreements.
 
    The accompanying combined financial statements include partnerships and
corporations which are under common control as follows:

    On June 30, 1997, the majority owner of SL Green Predecessor purchased the
remaining 90% interest in Praedium Bar Associates LLC, which was funded by a
loan from Lehman Brothers Holdings Inc., which as of that date is included in
the combined financial statements (see note 2).
 
    For the entities accounted for on the equity method, SL Green Predecessor
records its investments in partnerships and limited liability company at cost
and adjusts the investment accounts for its share of the entities' income or
loss and for cash distributions and contributions.
 
MANAGEMENT
 
    In order to maintain the Company's qualification as a REIT while realizing
income from management leasing and construction contracts from third parties,
all of the management operations with respect to properties in which the Company
will not own 100% of the interest are conducted through the Service
Corporations. In so doing, the Company should not incur a risk of this revenue
exceeding the 5% REIT Qualifying Income Test. The Company, through the Operating
Partnership, owns 100% of the non-voting common stock (representing 95% of the
total equity) of the Service Corporations. Through dividends on its equity
interest, the Operating Partnership will receive substantially all of the cash
flow (if any) from the Service Corporations' operations. All of the voting
common stock of the Service Corporations (representing 5% of the total equity)
is held by an SL Green affiliate. This controlling interest gives the SL Green

affiliate the power to elect all directors of the Service Corporations. The
Company accounts for its investment in the Service Corporations on the equity
basis of accounting on the basis that it has significant influence with respect
to management and operations.
 
    All of the management and leasing with respect to the properties contributed
and acquired by the Company are conducted through the Management LLC. The
Operating Partnership owns 100% interest in the Management LLC.
 
PARTNERSHIP AGREEMENT
 
    In accordance with the partnership agreement of the Operating Partnership
(the "Operating Partnership Agreement"), all allocations of distributions and
profits and losses are to be made in proportion to the percentage ownership
interests of their respective partners. As the managing general partner of the
Operating Partnership, the Company will be required to take such reasonable
efforts, as determined by it in its sole discretion, to cause the Operating
Partnership to distribute sufficient amounts to enable the payment of sufficient
distributions by the Company to avoid any federal income or excise tax at the
Company level as a consequence of a sale of a SL Green property. Under the
Operating Partnership agreement each limited partner will have the right to
redeem limited partnership interest for cash, or if the Company so elects shares
of common stock. In accordance with the Operating Partnership Agreement, the
Company is prohibited from selling 673 First Avenue and 470 Park Avenue South
through August 2009. Pursuant to the terms of the Operating Partnership's
partnership agreement, the Units issued to the Company's management and
continuing investors at the IPO may not, for up to two years from the IPO date,
transfer any of their rights or redeem their Units as a limited partner without
the consent of the Company.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
DEPRECIATION OF REAL ESTATE PROPERTIES

DEPRECIATION OF REAL ESTATE PROPERTIES (CONTINUED)
    Depreciation expense included amortization of the capital lease asset
amounted to $2,526 for the period August 21, 1997 to December 31, 1997 and $591
for the period January 1, 1997 to August 20, 1997, $788 and $579 in 1996 and
1995 respectively.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
RESTRICTED CASH
 
    Restricted cash primarily consists of security deposits held on behalf of
tenants.
 
REVENUE RECOGNITION
 
    Rental revenue is recognized on a straight-line basis over the term of the
lease. The excess of rents recognized over amounts contractually due pursuant to
the underlying leases are included in deferred rents receivable on the
accompanying balance sheets. The Company establishes an allowance on a current
basis a reserve for future potential tenant credit losses, which may occur
against this account. The balance reflected on the balance sheet is net of such
allowance.
 
RENT EXPENSE
 
    Rent expense is recognized on a straight-line basis over the initial term of
the lease. The excess of the rent expense recognized over the amounts
contractually due pursuant to the underlining lease is included in the deferred
lease payable in the accompanying combined balance sheet.
 
DEFERRED LEASE COSTS
 
    Deferred lease costs consist of fees and direct costs incurred to initiate
and renew operating leases and are amortized on a straight-line basis over the
initial lease term or renewal period as appropriate.
 
DEFERRED FINANCING COSTS
 
    Deferred financing costs represent commitment fees, legal and other third
party costs associated with obtaining commitments for financing which result in
a closing of such financing. These costs are amortized over the terms of the
respective agreements. Unamortized deferred financing costs are expensed when
the associated debt is refinanced before maturity. Costs incurred in seeking
financial transactions which do not close are expensed in the period incurred.
 
EARNINGS PER SHARE
 
    In 1997, Statement of Financial Accounting Standards (SFAS) No. 128,
Earnings Per Share ("SFAS No. 128"), replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive

effects of options, warrants and convertible securities. Diluted earnings per
share is very similar to the previously reported fully diluted earnings per
share. All earnings per share amounts for the quarter ended September 30, 1997
have been restated to conform to SFAS No. 128 requirements.
 
CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash investments and accounts receivable.
The Company places its cash investments with high quality institutions.
Management of the Company performs ongoing credit evaluation of its tenants and
requires certain tenants to provide security deposits. Though these security
deposits are insufficient to meet the terminal value of a tenant's lease
obligation, they are a measure of good faith and a source of funds to offset the
economic costs associated with lost rent and the costs associated with
retenanting the space. Although the SL Green Predecessors' buildings and new
acquisitions are all located in Manhattan, the tenants located in these
buildings operate in various industries and no single tenant represents a
dominant share of the Company's revenue and no tenant represents 10% of the
Company's revenue. Approximately 19% of the Company's revenue for the period
August 21, 1997 to December 31, 1997 was derived from 673 First Avenue.
 
STOCK-BASED COMPENSATION
 
    The Company accounts for its stock compensation arrangements under the
provisions of APB opinion No. 25, "Accounting for Stock Issued to Employees".
Since the stock options are granted by the Company at the fair value of the
shares at the date of grant, no compensation expense is recognized in the
financial statements. Awards of stock, restricted stock or employee loans to
purchase stock which may be forgiven over a period of time are expensed as
compensation expense on a current basis over the benefit period.
 
INCOME TAXES
 
    The Company is taxed as a REIT under Section 856(c) of the Internal Revenue
Code of 1986, as amended, commencing with the period August 21, 1997 to December
31, 1997. As a REIT, the Company generally is not subject to federal income tax.
To maintain qualification as a REIT, the Company must distribute at least 95% of
its REIT taxable income to its stockholders and meet certain other requirements.
If the Company fails to qualify as a REIT in any taxable year, the Company will
be subject to federal income tax on its taxable income at regular corporate
rates. The Company may also be subject to certain state and local taxes on its
income and property. Under certain circumstances, federal income and excise
taxes may be due on its undistributed taxable income. At December 31, 1997, the
Company believes it is in compliance with all REIT requirements and was not
subject to federal income taxes.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    SFAS 131, Disclosure about Segments of an Enterprise and Related Information
("SFAS No. 131") is effective for financial statements issued for periods

(A) Praedium Bar acquired the first mortgage related to the property in October,
    1996 which provides for substantially all the economic interest in the
    property and has the sole right to purchase the fee interest, (the property
    deed is in escrow), for a nominal cost; accordingly SL Green Predecessor has
    accounted for Praedium Bar investment as a ownership interest in the
    property. On June 30, 1997, the majority owner of SL Green Predecessor
    purchased the remaining 90% interest in Praedium Bar Associates, LLC for
    $6.3 million. The current owners of the fee interest in 36 West 44th Street
    and the leasehold interest in 35 West 43rd Street are obligated to transfer
    their interests, in this property to the Company not later than October 1,
    1998.

3. PROPERTY ACQUISITIONS
 
    In connection with the Formation Transaction (see note 1), the Company
acquired the first mortgage related to 1372 Broadway on August 21, 1997 which
provides for substantially all of the economic interest in the property and has
the sole right to purchase the fee interest; accordingly, the Company has
accounted for the 1372 Broadway investment as ownership interest in the
property. The Company purchased the fee interest in January 1998 for
approximately $1 million.
 
    On September 15, 1997, the Operating Partnership acquired the land and
building at 110 East 42nd Street for $30 million. The acquisition was funded by
proceeds of an LBHI loan and the Offering.
 
    On December 19, 1997, the Operating Partnership exercised the Company's
option to acquire an interest in 17 Battery Place for approximately $59 million.
In connection with this acquisition, the Company also loaned $15.5 million to
the co-tenant at 17 Battery Place. The mortgage receivable bears interest at 12%
and is due September 30, 1998 and is secured by a first mortgage on the
co-tenant's interest in the property. The cash required to purchase the
investment and make the loan were funded through borrowings under the Company's
senior unsecured revolving credit facility.
 
    In connection with the acquisition of 17 Battery Place, prior to January 1,
1999, the Company is required to make available up to 153,000 rentable square
feet of vacant office space to tenants of 17 Battery Place, who currently occupy
portions of the co-tenants space. In order to convert the upper floors of the
South Building into hotel/ residential space, the co-tenant plans to exercise
relocation options to relocate tenants from its hotel/ residential space to the
Company's office space.
 
    On December 30, 1997 the Operating Partnership acquired a condominium
ownership interest at 633 Third Avenue for $10.5 million and a capital reserve
of $1 million. The acquisition was funded by proceeds from a mortgage loan on 50
West 23rd Street and cash on hand.
 
    The following table summarizes, on an unaudited pro forma basis, the
combined results of operations of the Company for the years ended December 31,
1997 and 1996 as though each acquisition described above and each acquisition
included in the Offering and Formation Transactions was made on January 1, 1996.

(A) These loans were repaid in connection with proceeds from the Offering.
 
(B) In January, 1996, the first mortgage was bifurcated into a first and second
    mortgage; the second mortgage was acquired by an unrelated entity for no
    consideration. In December 1996 the holder of the second mortgage on 70 West
    36th Street forgave the indebtedness for no consideration; as a result SL
    Green Predecessor recognized extraordinary income of $8,961. The remaining
    unpaid portion of the first mortgage was paid during August 1997.
 
(C) The Lehman Brothers Holdings Inc. loan is collateralized by partnership
    interests in certain property-owning entities.
 
    On December 19, 1997 the Company entered into a $140 million three year
senior unsecured revolving credit facility (the "Credit Facility") due December
2000. Availability under the Credit Facility may be limited to an amount less
than $140 million which is calculated by several factors including recent
acquisition activity and most recent quarterly property performance. Outstanding
loans under the Credit Facility bear interest at a rate per annum equal to the
London Interbank Offered Rate ("LIBOR") applicable to each interest period plus
130 basis points to 145 basis points per annum. The Credit Facility requires the
Company to comply with certain covenants, including but not limited to,
maintenance of certain financial ratios. At December 31, 1997 the outstanding
amount of indebtedness under the Credit Facility was $76 million, and the
interest rate on such indebtedness was 7.265% per annum. At December 31, 1997
the Company's borrowing availability was $40 million.
 
    The interest rate of the existing mortgage loan which is collateralized by
50 West 23rd Street can be fixed in the future at 150 basis points plus the ten
year US Treasury Note rate and maturing co-terminously with the underlying
mortgage note when certain income targets are met.
 
PRINCIPAL MATURITIES
 
    Combined aggregate principal maturities of mortgages and notes payable as of
December 31, 1997 are as follows:

MORTGAGE RECORDING TAX--HYPOTHECATED LOAN
 
    The Operating Partnership received loans totaling approximately $69.5
million from LBHI. These loans are collateralized by the mortgages encumbering
the Operating Partnership's interests in 1140 Avenue of the Americas and 110
East 42nd Street. The loans are also collateralized by an equivalent amount of
the Company's cash which is held by LBHI and invested in US Treasury securities.
Interest earned on the cash collateral is applied by Lehman to service the loans
which interest rate is commensurate with that of the portfolio of US Treasury
securities, which mature on May 15, 1998. The Operating Partnership and LBHI
each have the right of offset and therefore the loans and the cash collateral
have been presented on a net basis in the consolidated balance sheet at December
31, 1997. The purpose of these loans is to temporarily preserve mortgage
recording tax credits for future potential acquisitions of real property which
the Company may make, the financing of which may include property based debt,
for which these credits would be applicable and provide a financial savings.
 
6. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The following disclosures of estimated fair value were determined by
management, using available market information and appropriate valuation
methodologies. Considerable judgment is necessary to interpret market data and
develop estimated fair value. Accordingly, the estimates presented herein are
not necessarily indicative of the amounts the SL Green Predecessor could realize
on disposition of the financial instruments. The use of different market
assumptions and/or estimation methodologies may have a material effect on the
estimated fair value amounts.
 
    Cash equivalents, variable rate mortgages and fixed rate debt are carried at
amounts which reasonably approximate their fair values.
 
    Disclosure about fair value of financial instruments is based on pertinent
information available to management as of December 31, 1997. Although management
is not aware of any factors that would significantly affect the reasonable fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since that date and current estimates of fair
value may differ significantly from the amounts presented herein.
 
7. RENTAL INCOME
 
    The Operating Partnership is the lessor and the sublessor to tenants under
operating leases with expiration dates ranging from 1998 to 2011. The minimum
rental amounts due under the leases are generally either subject to scheduled
fixed increases or adjustments. The leases generally also require that the
tenants reimburse the Company 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 leases in effect at
December 31, 1997 are as follows:

9. STOCKHOLDERS' EQUITY
 
    The authorized capital stock of the Company consists of $200 million shares
of capital stock, $.01 par value, of which the Company has authorized the
issuance of up to 100 million shares of Common Stock $0.01 par value per share,
75 million shares of excess stock, at $0.01 par value per share and 25 million
shares of preferred stock, par value $0.01 per share. Under the Company's
Charter, the Board of Directors will have authority to issue, without any
further action by the stockholders, shares of capital stock in one or more
series having such preferences, conversion and other rights, voting powers,
restrictions, limitations as to dividends, qualifications and terms and
conditions of redemption as the Board of Directors may determine.
 
    During August 1997, the Company instituted the 1997 Stock Option and
Incentive Plan (The "Stock Option Plan"). The Stock Option Plan authorizes (i)
the grant of stock options that qualify as incentive stock options under Section
422 of the Code ("ISOs"), (ii) the grant of stock options that do not so qualify
("NQSOs"), (iii) the grant of stock options in lieu of cash Directors' fees and
employee bonuses, (iv) grants of shares of Common Stock, in lieu of compensation
and (v) the making of loans to acquire shares of Common Stock, in lieu of
compensation. The exercise price of stock options will be determined by the
Compensation Committee, but may not be less than 100% of the fair market value
of the shares of Common Stock on the date of grant in the case of ISOs; provided
that, in the case of grants of NQSOs granted in lieu of cash Director's fees and
employee bonuses, the exercise price may not be less than 50% of the fair market
value of the shares of Common Stock on the date of grant. At December 31, 1997,
1.1 million shares of Common Stock are reserved for exercise of warrants and
stock options.
 
    Options granted under the 1997 qualified stock option plan are exercisable
at the fair market value on the date of grant and, subject to termination of
employment, expire ten years form the date of grant, are not transferable other
than on death, and are exercisable in three equal annual installments commencing
one year from the date of grant (with the exception of 10,000 options which have
a vesting period of one year).

compensation arrangements whereby no compensation cost related to stock options
is deducted in determining net income. Had compensation cost for the Company's
stock option plans been determined pursuant to Financial Accounting Standards
Board Statement No. 123 ("SFAS No. 123"), "Accounting for Stock-Based
Compensation," the Company's pro forma net income and earnings per share would
have differed. The Black-Scholes option pricing model estimates fair value of
options using subjective assumptions which can materially effect fair value
estimates and, therefore, do not necessarily provide a single measure of fair
value of options. Using the Black-Scholes option pricing model for all options
granted on or after August 20, 1997 and a risk-free interest rate of 5.00%,
dividend yield on common stock of 5%, a volatility factor for the market price
of the Company's Common Stock of .259 and a weighted-average expected life of
options of approximately four years, the Company's pro forma net income, basic
pro forma earnings per share and diluted pro forma earnings per share would have
been $3,439, $0.28 and $0.28, respectively, for the period August 20, 1997 to
December 31, 1997. For purposes of these pro forma disclosures, the estimated
fair value of options is amortized over the options' vesting period. Since the
number of options granted and their fair value may vary significantly from year
to year, the pro forma compensation expense in future years may be materially
different.
 
EARNINGS PER SHARE
 
    Basic and diluted earnings per common share for the period ended December
31, 1997 have been computed based upon weighted average equivalent shares
outstanding of 12,292 and 12,404 respectively. The difference in the weighted
average shares outstanding represents the inclusion of common share equivalents
from options issued and outstanding at December 31, 1997 in the calculation of
diluted earnings per share which is not included in basic earnings per share.
 
10. BENEFIT PLANS
 
    The building employees of the individual partnerships are covered by
multi-employer defined benefit pension plans and post-retirement health and
welfare plans. Contributions to these plans amounted to $35, $44, $30 and $7
during the periods August 21, 1997 to December 31, 1997, January 1, 1997 to
August 20, 1997 and the years ended December 31, 1996 and 1995, respectively.

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.
 
401(K) PLAN
 
    During August 1997, the Company implemented a 401(k) Savings/ Retirement
Plan (the "401(k) Plan") to cover eligible employees of the Company and any
designated affiliate. The 401(k) Plan permits eligible employees of the Company
to defer up to 15% of their annual compensation, subject to certain limitations
imposed by the Code. The employees' elective deferrals are immediately vested
and non-forfeitable upon contribution to the 401(k) Plan. The Company did not
make any contributions to the 401(k) Plan during 1997.
 
11. COMMITMENTS AND CONTINGENCIES
 
    The Company and the Operating Partnership are not presently involved in any
material litigation nor, to their knowledge, is any material litigation
threatened against them or their properties, other than routine litigation
arising in the ordinary course of business. Management believes the costs, if
any, incurred by the Company and the Operating Partnership related to this
litigation will not materially affect the financial position, operating results
or liquidity of the Company and the Operating Partnership.
 
    The Company has entered into employment agreements with certain executive
officers. Six executive officers have three year employment agreements which
expire in August 2000. The base compensation associated with these employment
agreements total $1,100 annually.
 
    The SL Green Predecessor is the lessor and sub-lessor of commercial
buildings under operating leases with expiration dates ranging from 1998 to
2031. The minimum rental amounts due under the leases are generally either
subject to scheduled fixed increases or adjustments. The leases generally also
require that the tenants reimburse the SL Green Predecessor for increases in
certain operating costs and real estate taxes above their base year costs.
 
    In April 1988, the SL Green Predecessor entered into a lease agreement for
property at 673 First Avenue in New York City, which has been capitalized for
financial statement purposes. Land was estimated to be approximately 70% of the
fair market value of the property. The portion of the lease attributed to land
is classified as an operating lease and the remainder as a capital lease. The
initial lease term is 49 years with an option for an additional 26 years.
Beginning in lease year 11 and 25, the lessor is entitled to additional rent as
defined by the lease agreement.
 
    The Company leases 673 First Avenue with a cost basis of $12,208 and
cumulative amortization of $2,284 under a capital lease at December 31, 1997.
The following is a schedule of future minimum lease payments under capital
leases and noncancellable operating leases with initial terms in excess of one
year as of December 31, 1997:

to mortgages paid in connection with the Formation Transactions were expensed
and are reflected in the Company's financial statements as an extraordinary
loss.

15. SUBSEQUENT EVENTS
 
ACQUISITION OF 321 AND HELMSLEY PROPERTIES
 
    The Company announced in February 1998 three (3) additional properties
placed under contract for purchase at a cost of approximately $176 million. The
properties aggregate rentable area is approximately 1.7 million square feet. The
Company closed two of these acquisitions in March 1998 and the third is expected
to close during the second quarter of 1998. Acquisition financing for these
properties was obtained through a commitment from Lehman Brothers Holdings, Inc.
for a short term acquisition facility for up to $275 million. The Company used
these loan proceeds to (i) re-pay the current balance on its line of credit ($93
million at March 1, 1998), (ii) fund the closing of the announced acquisitions
and (iii) provide for general corporate purposes. The three acquisition
properties are as follows:
 
321 WEST 44TH STREET
 
    On January 26, 1998 SL Green announced it had placed under contract a
200,000 square foot office building at 321 West 44th Street. The property was
contracted to be acquired for $17 million in cash and was approximately 96%
leased at the time of acquisition. Closing is anticipated to occur during the
second quarter of 1998.

15. SUBSEQUENT EVENTS (CONTINUED)
ACQUISITION OF HELMSLEY PROPERTIES (CONTINUED)
 
    On February 20, 1998 the Company announced it had placed under contract for
purchase of the fee interest in one property (1466 Broadway) and the operating
interest of another property (420 Lexington Avenue, the Graybar Building) from
the Helmsley organization. The Graybar building is located adjacent to Grand
Central Station and encompasses approximately 1.2 million square feet. 1466
Broadway is located in the heart of Times Square at 42nd Street and Broadway
encompassing approximately 290,000 square feet. The aggregate base purchase
price for the two properties is $142 million. At the time the acquisition was
announced, the Graybar building was 83% leased and 1466 Broadway was
approximately 87% leased. The Company closed on these acquisitions on March 18,
1998.
 
ACQUISITION FINANCING
 
    Subsequent to December 31, 1997, the Company asked the Credit Facility
banking group to temporarily relieve the Company from its obligations under the
financial covenants of the Credit Facility, in order to close an additional
financing necessary to acquire the Helmsley properties (the "Acquisition
Facility"). This Acquisition Facility which closed in March financed the
Helmsley properties, paid-off the outstanding balance on the Company's Credit
Facility and provide on going liquidity for future acquisition and corporate
needs. The term of the Acquisition Facility is one year. The interest rate is
determined by a schedule of the percent of loan commitment outstanding and the
duration of the outstanding commitments, ranging from 170 basis points over
LIBOR to 300 basis points over LIBOR (7.3875% at date of borrowing). The
original Credit Facility will remain committed but unused until the Acquisition
Facility is paid off through either permanent debt or an equity financing and
the Company's financial covenant obligations are restored.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors of
SL Green Realty Corp.
 
    We have audited the accompanying combined balance sheet of the uncombined
joint ventures of SL Green Predecessor as of December 31, 1996 and the related
combined statements of operations, owners' deficit and cash flows for the period
from January 1, 1997 to August 20, 1997 and for each of the two years in the
period ended December 31, 1996. These financial statements are the
responsibility of SL Green Predecessor's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the combined financial statements referred to above present
fairly in all material respects, the combined financial position of the
uncombined joint ventures of SL Green Predecessor at December 31, 1996 and the
combined results of its operations and its cash flows for the period from
January 1, 1997 to August 20, 1997 and for each of the two years in the period
ended December 31, 1996 in conformity with generally accepted accounting
principles.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
    The uncombined joint ventures of SL Green Predecessor are engaged in the
business of owning, managing and leasing, and repositioning Class B office
properties in Manhattan, New York.
 
FORMATION TRANSACTIONS
 
    Concurrently with the consummation of the initial public offering of SL
Green Realty Corp. (the "REIT") Common Stock (the "Offering"), which was
completed on August 20, 1997 the REIT and a newly formed limited partnership, SL
Green Operating Partnership, L.P. (the "Operating Partnership"), together with
the partners and members of the affiliated partnerships of the SL Green
Predecessor and other parties which hold ownership interests in the properties
(collectively, the "Participants"), engaged in certain formation transactions
(the "Formation Transactions"). The Formation Transactions were designed to (i)
enable the REIT to raise the necessary capital to acquire the remaining
interests in the uncombined joint ventures of the SL Green Predecessor and repay
certain mortgage debt relating thereto and pay other indebtedness, (ii) enable
the REIT to acquire properties, (iii) fund costs, capital expenditures, and
working capital, (iv) provide a vehicle for future acquisitions, (v) enable the
REIT to comply with certain requirements under the Federal income tax laws and
regulations relating to real estate investment trusts, and (vi) preserve certain
tax advantages for certain Participants.
 
    The REIT is the sole general partner in the Operating Partnership. The
Operating Partnership received a contribution of interests in the real estate
properties in exchange for units of limited partnership interests in the
Operating Partnership and/or cash. The REIT is a fully integrated
self-administered and self-managed.
 
PRINCIPLES OF COMBINATION
 
    The uncombined joint ventures of the SL Green Predecessor is not a legal
entity but rather a combination of real estate properties (collectively, the
"Properties") and interests in entities that are organized as partnerships and a
limited liability company. The operations of the properties are included in the
financial statements of the SL Green Predecessor from the date of acquisition
and management. All significant intercompany transactions and balances have been
eliminated in combination.
 
    Capital contributions, distributions and profits and losses are allocated to
the owners in accordance with the terms of the applicable agreements.

(A) Praedium Bar acquired the first mortgage related to the property in October,
    1996 which provides for substantially all the economic interest in the
    property and has the sole right to purchase the fee interest, (the property
    deed is in escrow), for a nominal cost; accordingly SL Green Predecessor has
    accounted for Praedium Bar investment as an ownership in the property. On
    June 30, 1997, the majority owner of SL Green Predecessor purchased the
    remaining 90% interest in Praedium Bar Associates, LLC for $6.3 million.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
DEPRECIATION OF REAL ESTATE PROPERTIES
 
Depreciation and amortization is computed on the straight-line method as
follows:
 
<TABLE>
<CAPTION>
CATEGORY                                                     TERM

Building...................................................  40 years
Property under capital lease...............................  49 years
Building improvements......................................  remaining life of the building
Tenant improvements........................................  remaining life of the lease
</TABLE>
 
    Depreciation expense including the amortization of the capital lease asset
amounted to $2,917, and $2,999 in 1996 and 1995 respectively. For the period
ended August 20, 1997 depreciation expense amounted to $1,859.
 
CASH AND CASH EQUIVALENTS
 
    The SL Green Predecessor considers highly liquid investments with a maturity
of three months or less when purchased to be cash equivalents.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
RESTRICTED CASH
 
    Restricted cash consists of security deposits.
 
REVENUE RECOGNITION
 
    Rental revenue is recognized on a straight-line basis over the term of the
lease. The excess of rents recognized over amounts contractually due pursuant to
the underlying leases are included in deferred rents receivable on the
accompanying combined balance sheet. Contractually due but unpaid rents are
included in other assets on the accompanying combined balance sheet. Certain
lease agreements provide for reimbursement of real estate taxes, insurance and
certain common area maintenance costs and rental increases tied to increases in
certain economic indexes.
 
DEFERRED LEASE COSTS
 
    Deferred lease costs consist of fees and direct costs incurred to initiate
and renew operating leases, and are amortized on a straight-line basis over the
initial lease term or renewal period as appropriate.
 
DEFERRED FINANCING COSTS
 
    Deferred financing costs are amortized over the terms of the respective
agreements. Unamortized deferred financing costs are expensed when the
associated debt is retired before maturity.
 
CAPITALIZED INTEREST
 
    Interest for borrowings used to fund development and construction is
capitalized to individual property costs.
 
RENT EXPENSE
 
    Rent expense is recognized on a straight-line basis over the initial term of
the lease. The excess of the rent expense recognized over the amounts
contractually due pursuant to the underlining lease is included in the deferred
lease payable in the accompanying combined balance sheet.
 
INCOME TAXES
 
    The properties are not taxpaying entities for Federal income tax purposes,
and, accordingly, no provision or credit has been made in the accompanying
financial statements for Federal income taxes. Owners' allocable shares of
taxable income or loss are reportable on their income tax returns.
 
CONCENTRATION OF REVENUE AND CREDIT RISK
 
    Approximately 60% of the properties revenue for the two years ended December
31, 1996 were derived from 673 First Avenue. Approximately 50% of the properties
revenue for the period January 1, 1997 to August 20, 1997 were derived from 673
First Avenue. The loss or a material decrease in revenues from this building for
any reason may have a material adverse effect on the properties. In addition

    The third mortgage requires the monthly payment of minimum interest at 6%.
    The difference between the minimum interest and the base interest of 10.98%
    may be deferred until the maturity of the mortgage. The mortgage requires
    additional interest of 50% of adjusted gross revenue, as defined in the
    mortgage agreement, of the property for the applicable loan year. If the
    total loan balance exceeds 90% of the appraised value in lieu of payments of
    additional interest all of the adjusted gross revenue shall be paid and
    applied as a reduction of the principal indebtedness until such time as the
    loan balance is reduced to 90% of the appraised value. Upon payment of the
    outstanding principal balance at maturity or on another date shared
    appreciation interest, as defined in the mortgage agreement will be due. The
    holder of the mortgage is entitled to an annual rate of return on the
    mortgage of 13%. If the annual rate of return is less than 13%, the share
    appreciation interest will be increased to the percentage necessary to
    provide the mortgage holder with such return. Additional interest of $19 was
    due in 1996 and was unpaid as of December 31, 1996.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The following disclosures of estimated fair value were determined by
management, using available market information and appropriate valuation
methodologies. Considerable judgment is necessary to interpret market data and
develop estimated fair value. Accordingly, the estimates presented herein are
not necessarily indicative of the amounts the properties could realize on
disposition of financial instruments. The use of different market assumptions
and/or estimation methodologies may have a material effect on the estimated fair
value amounts.
 
    Cash equivalents and variable rate mortgages are carried at amounts which
reasonably approximate their fair values. Estimated fair value is based on
anticipated settlement in connection with the REIT formation, interest rates and
other related factors currently available to the properties for issuance of debt
with similar terms and remaining maturities. The fair value by mortgage type as
of December 31, 1996 is as follows:

    Disclosure about fair value of financial instruments is based on pertinent
information available to management as of December 31, 1996. Although management
is not aware of any factors that would significantly affect the reasonable fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since that date and current estimates of fair
value may differ significantly from the amounts presented herein.
 
6. LEASE AGREEMENTS
 
CAPITAL LEASE
 
    In April 1988, the SL Green Predecessor entered into a lease agreement for
property at 673 First Avenue in New York City, which has been capitalized for
financial statement purposes. Land was estimated to be approximately 70% of the
fair market value of the property. The portion of the lease attributed to land
is classified as an operating lease and the remainder as a capital lease. The
initial lease term is 49 years with an option for an additional 26 years.
Beginning in lease year 11 and 25, the lessor is entitled to additional rent as
defined by the lease agreement.
 
    Rent expense amounted to approximately $3,756 for each year ended December
31, 1996 and 1995 respectively. For the period January 1, 1997 to August 20,
1997 rent expense amounted to approximately $2,425.

8. BENEFIT PLAN
 
    The building employees of the individual partnerships are covered by
multi-employer defined benefit pension plans and post-retirement health and
welfare plans. Contributions to these plans amounted to $42 and $30 in 1996 and
1995 respectively; and $38 for the period January 1 to August 20, 1997. 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.

9. CONTINGENCIES
 
    SL Green Predecessor is party to a variety of legal proceedings relating to
the ownership of the Properties arising in the ordinary course of business. SL
Green Predecessor management believes that substantially all of these
liabilities are covered by insurance. All of these matters, taken together, are
not expected to have a material adverse impact on the uncombined joint venture
of SL Green Predecessor's, financial position, results of operations or cash
flows.
 
10. ENVIRONMENTAL MATTERS
 
    The management of SL Green Predecessor believes that the properties are in
compliance in all material respects with applicable federal, state and local
ordinances and regulations regarding environmental issues. Management is not
aware of any environmental liability that management believes would have a
material adverse impact on the uncombined joint venture of SL Green
Predecessor's financial position, results of operations or cash flows.
Management is unaware of any instances in which it would incur significant
environmental cost if any of the properties were sold.

                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of the Bar Building, (the "Property"), located in the borough
of Manhattan in New York City.
 
    The accompanying financial statements have 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 financial
statements exclude certain expenses that may not be comparable to those expected
to be incurred by the SL Green Realty Corp. in the proposed future operations of
the Property. Items excluded consist of interest, amortization and depreciation.
 
    On September 30, 1996 Praedium Bar Associates, LLC ("Praedium") acquired the
mortgage secured by the property and SL Green Predecessor acquired its interest
in Praedium.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements 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 over amounts so recognized pursuant to the
underlying leases amounted to approximately $60 and $29 (unaudited) for the year
ended December 31, 1996 and the six months ended June 30, 1997, respectively.
 
4. CONCENTRATION OF REVENUE
 
    Approximately 11% and 13% of the Bar Building's revenue for the year ended
December 31, 1996 and the six months ended June 30, 1997, respectively, was
derived from one tenant.
 
5. MANAGEMENT AGREEMENTS
 
    There was no management fee incurred for the period January 1, through June
28, 1996. The compensation for management services incurred from June 28,
through September 30, 1996 included an initial one time start-up fee of $7,500
and thereafter, a monthly fixed fee of $7,500. For the period of October 1,
through December 31, 1996 the management fee was based on three percent (3%) of
gross receipts from the Property.
 
6. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with term
expiration dates ranging from 1997 to 2006. 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.

                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of 1372 Broadway (the "Property"), located in the New York
City garment district, which is principally leased by garment, banking, and
retail tenants.
 
    The accompanying financial statements have 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 financial
statements exclude certain expenses that may not be comparable to those expected
to be incurred by the SL Green Realty Corp. in the proposed future operations of
the Property. Items excluded consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
3. REVENUE RECOGNITION
 
    The Property is being 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 so recognized over amounts due pursuant to the
underlying leases amounted to approximately $22 and $(117) (unaudited) for the
year ended December 31, 1996 and the six months ended June 30, 1997
respectively.
 
4. MANAGEMENT AGREEMENTS
 
    The Property, as of July 1, 1997, is managed by Axiom Real Estate Management
("Axiom"), Inc. for a fixed annual amount of $37 plus an allocation of overhead
costs which were approximately $354 in 1996. Prior to May 1, 1997, the Property
was managed by Winthrop Management for a fee of 5% of gross rental receipts.
 
5. INSURANCE COSTS
 
    Insurance costs represent 1372 Broadway's portion of an umbrella policy held
by Winthrop Management.

6. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with
expiration dates ranging from 1997 to 2010. Most leases contain renewal options
at the election of the lessee. The lease agreements generally contain provisions
for reimbursements of real estate taxes and operating expenses over base year
amounts. Future minimum lease receipts under non-cancelable operating leases as
of December 31, 1996 (exclusive of renewal option periods) were as follows:

7. CONCENTRATION OF REVENUE
 
    Approximately 42% and 40% of 1372 Broadway's revenue for the year ended
December 31, 1996 and for the six months ended June 30, 1997 were derived from
three tenants.
 
8. CONTINGENCY
 
    As of March 12, 1996, 1372 Broadway has been in legal proceedings related to
grievances filed by the Service Employees International Union for allegedly
violating the terms of their agreement for cleaning services. At this time
management can not estimate the loss, if any, associated with this litigation.
 
9. INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The financial statement for the six months ended June 30, 1997 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 is not necessarily indicative of the results to be obtained
for a full fiscal year.
 
10. SUBSEQUENT EVENT
 
    On January 31, 1997, a tenant entered into an agreement whereby certain
space leased by the tenant was terminated for a fee of $1,350.

1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of 1140 Avenue of the Americas, (the "Property"), located in
the borough of Manhattan in New York City.
 
    The accompanying financial statements have 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 financial
statements exclude certain expenses that may not be comparable to those expected
to be incurred by the SL Green Realty Corp. in the proposed future operations of
the Property. Items excluded consist of non-capital lease interest, amortization
and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements 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
so recognized amounted to approximately $59 and $54 (unaudited) for the year
ended December 31, 1996 and the six months ended June 30, 1997, respectively.
 
4. CONCENTRATION OF REVENUE
 
    Approximately 10% of 1140 Avenue of the Americas' revenue for the year ended
December 31, 1996 and the six months ended June 30, 1997, respectively was
derived from one tenant.
 
5. MANAGEMENT AGREEMENTS
 
    During 1996 and the period ended June 30, 1997 the Property was managed by
Murray Hill Property Management, Inc. During the period from January 1, 1996 to
June 30, 1997 the management and asset management fees were based on three
percent (3%) and one percent (1%) of gross collections from the Property,
respectively.
 
6. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with term
expiration dates ranging from 1997 to 2007. 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.

    The Property operates under a net ground lease with a term expiration date
of 2016, with an option to renew for an additional 50 years. The minimum rental
amounts due under the ground lease is subject to increases every 21 years based
on four and a half percent (4 1/2%) of the fair and reasonable market value of
the unencumbered land. The ground lease requires that the tenant is responsible
for the payment for all expenses. The current annual rent for the period
commencing January 1, 1997 through December 31, 2016 was in arbitration due to a
disagreement relating to the market value of the land and has been recently
resolved in the amount of approximately $380 (unaudited).
 
7. INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The financial statement for the six months ended June 30, 1997 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 is not necessarily indicative of the results to be obtained
for a full fiscal year.

1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of the property, located at 110 East 42nd Street, in the Grand
Central District sub-market, in the borough of Manhattan in New York City, (the
"Property"). The Property is comprised of a building containing 250,548 square
feet.
 
    The accompanying financial statements have 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 financial
statements exclude certain expenses that may not be comparable to those expected
to be incurred by SL Green Realty Corp., in the proposed future operations of
the Property. The Property was acquired by SL Green on September 15, 1997. Items
excluded consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements 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
so recognized amounted to approximately $280 for the year ended December 31,
1996. For the six months ended June 30, 1997 amounts so recognized exceeded
amounts due pursuant to the underlying leases by $82 (unaudited).
 
4. CONCENTRATION OF REVENUE
 
    Approximately 60% and 18% of the Property's revenue for the year ended
December 31, 1996 and the six months ended June 30, 1997 (unaudited),
respectively was derived from one tenant.
 
5. MANAGEMENT AGREEMENTS
 
    During 1996 and the period ended June 30, 1997 the Property was managed by
Metromedia, Inc. During the year ended December 31, 1996 the management fees
were based on quarterly fixed payments of $13 and administrative salaries.
During the six months ended June 30, 1997 (unaudited) the management fees were
based on quarterly fixed payments of $25 and administrative salaries.
 
6. RELATED PARTY TRANSACTIONS
 
    Office space is leased to companies that have shareholders who are also
partners in the partnership which owned the Property. Total rents from these
affiliated companies totaled $82 and $50 at December 31, 1996 and June 30, 1997
(unaudited), respectively.
 
    A company controlled by partners of the partnership which owned the Property
provided management and administrative services to the Property. The management
fee for these services were $172 and

expiration dates ranging from 1997 to 2007. 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.

thereafter for non-cancelable operating leases as of December 31, 1996
(exclusive of renewal option periods) are as follows:

                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of 17 Battery Place, located in the World Trade Center
sub-market, in the borough of Manhattan in New York City. The property is
comprised of interconnected office buildings (North and South) containing a
total of approximately 1,221,481 square feet (which space is currently rented or
available for use on a commercial basis). Through its interest in a cotenancy,
SLG 17 Battery LLC, ("Green LLC") a New York limited liability company
wholly-owned by SL Green Realty Corp. ("SL Green"), purchased the entire North
Building and portions of the ground floor and floors one through thirteen of the
South Building, encompassing approximately 806,927 square feet (the "Office
Space"). An unrelated third party ("Third Party") has through its interest in
the cotenancy purchased portions of the ground floor and floors fourteen through
thirty-one of the South Building which represents the remaining 414,554 square
feet of the property. The Third Party plans to convert its space into a hotel
and residential units, (the "Hotel/ Residential Space"). Green LLC has entered
into a cotenancy agreement with the Third Party and SL Green has financed the
Third Party's purchase through the issuance of a mortgage. The cotenancy
agreement provides for the allocation of revenue and expenses substantially
consistent with the Third Party's and Green LLC's ownership interest. It is the
intention of the parties to convert the property to condominium ownership. The
statements of revenues and certain expenses present the activity of the Office
Space purchased by SL Green.
 
    All revenues and expenses have been allocated between the Office and
Hotel/Residential Space. The allocation method used for base rent and
escalations were based on specific identification of the tenants located in the
specific floors being purchased. Expenses were allocated based on an agreed upon
allocation between Green LLC and the Third Party.
 
    The accompanying financial statements have 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 financial
statements exclude certain expenses that may not be comparable to those expected
to be incurred by SL Green in its proposed future operations. Items excluded
consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
3. REVENUE RECOGNITION
 
    The Office Space 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 recognized over amounts due pursuant to the
underlying leases amounted to approximately $507 and $270 (unaudited) for the
year ended December 31, 1996 and the nine months ended September 30, 1997,
respectively.

4. CONCENTRATION OF REVENUE
 
    Approximately 62% of the Office Space's revenue for the year ended December
31, 1996 and the nine months ended September 30, 1997, respectively was derived
from two tenants.
 
5. MANAGEMENT AGREEMENTS
 
    During 1996 and the period ended September 30, 1997 the property manager was
SL Green Management, Inc. During the period from January 1, 1996 to September
30, 1997 the management fees were based on two percent (2%) of gross
collections. In addition, a $15,000 monthly asset management fee was paid to
Victor Capital Group.
 
6. LEASE AGREEMENTS
 
    The Office Space is being leased to tenants under operating leases with term
expiration dates ranging from 1997 to 2009. The minimum rental amounts due under
the leases are generally subject to scheduled fixed increases. The leases
generally also require that the tenants reimburse 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, 1996 (exclusive of renewal
option periods) are as follows:

</TABLE>
 
7. LEASE RESTRICTIONS
 
    In connection with the cotenancy agreement (Note 1), prior to January 1,
1999, Green LLC is required to make available up to 153,000 rentable square feet
of vacant Office Space to tenants of 17 Battery Place, who currently occupy
portions of the Hotel/Residential Space. In order to convert the upper floors of
the South Building, the Third Party will exercise relocation options to relocate
tenants from the Hotel/Residential Space to Office Space.
 
8. INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The financial statement for the nine months ended September 30, 1997 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 is not necessarily indicative of the results to be
obtained for a full fiscal year.

management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    The accompanying statement of revenues and certain expenses was prepared for
the purposes of complying with the rules and regulations of the Securities and
Exchange Commission for inclusion in Form S-11 of SL Green Realty Corp., and is
not intended to be a complete presentation of 17 Battery Place as described in
Note 1, revenues and expenses.
 
    In our opinion, the financial statement referred to above presents fairly,
in all material respects, the revenues and certain expenses of 17 Battery Place
as described in Note 1, for the year ended December 31, 1996 in conformity with
generally accepted accounting principles.

              NOTES TO STATMENTS OF REVENUES AND CERTAIN EXPENSES
                             (DOLLARS IN THOUSANDS)
                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION
 
    Presented herein are the statements of revenues and certain expenses related
to the operations of 17 Battery Place, located in the World Trade Center
sub-market, in the borough of Manhattan in New York City. The property is
comprised of interconnected office buildings (North and South) containing a
total of approximately 1,221,481 square feet (which space is currently rented or
available for use on a commercial basis). Through its interest in a cotenancy,
SLG 17 Battery LLC, ("Green LLC") a New York limited liability company
wholly-owned by SL Green Realty Corp. ("SL Green"), purchased the entire North
Building and portions of the ground floor and floors one through thirteen of the
South Building, encompassing approximately 806,927 square feet (the "Office
Space"). An unrelated third party ("Third Party") has through its interest in
the cotenancy purchased a portion of the ground floor and floors fourteen
through thirty-one of the South Building which represents the remaining 414,554
square feet of the property. The Third Party plans to convert its space into a
hotel and residential units, (the "Hotel/ Residential Space"). Green LLC has
entered into a cotenancy agreement with the Third Party and has financed the
Third Party's purchase of its property through the issuance of a mortgage. The
cotenancy agreement provides for the allocation of revenue and expenses
substantially consistent with the Third Party's and Green LLC's ownership
interest. The statement of revenues and certain expenses presents the activity
of the Hotel/Residential Space which is the collateral for the mortgage issued
by SL Green.
 
    All revenues and expenses have been allocated between the Office and
Hotel/Residential Space. The allocation method used for base rent and
escalations were based on specific identification of the tenants located in the
specific floors purchased. Expenses were allocated based on an agreed upon
allocation between Green LLC and the Third Party.
 
    The accompanying financial statements have been prepared in accordance with
the applicable rules and regulations of the Securities and Exchange Commission
for a mortgage collateralized by real estate properties. Since it is intended
that the Hotel/Residential Space is to be converted to a hotel/ residential
units, future operations will be substantially different from those presented in
these statements of revenues and certain expenses. The financial statements
exclude certain expenses that may not be comparable to those expected to be
incurred by the Third Party in its proposed future operations. Items excluded
consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
3. REVENUE RECOGNITION
 
    The Third Party's interest currently 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 recognized over amounts due
pursuant to the underlying leases amounted to approximately $114 and $154
(unaudited) for the year ended December 31, 1996 and the nine months ended
September 30, 1997, respectively.

                               DECEMBER 31, 1996
 
4. CONCENTRATION OF REVENUE
 
    Approximately 40% and 25% of the revenue for the year ended December 31,
1996 and the nine months ended September 30, 1997, were derived from three and
two tenants, respectively.
 
5. MANAGEMENT AGREEMENTS
 
    During 1996 and the period ended September 30, 1997 the property manager was
SL Green Management, Inc. During the period from January 1, 1996 to September
30, 1997 the management fees were based on two percent (2%) of gross
collections. In addition, a $15,000 monthly asset management fee was paid to
Victor Capital Group.
 
6. LEASE AGREEMENTS
 
    The Third Party's interest is being leased to tenants under operating leases
with term expiration dates ranging from 1997 to 2005. The minimum rental amounts
due under the leases are generally subject to scheduled fixed increases. The
leases generally also require that the tenants reimburse 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, 1996 (exclusive of renewal
option periods) are as follows:

7. INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The financial statement for the nine months ended September 30, 1997 is
unaudited, however, in the opinion of management all adjustments, (consisting
solely of normal recurring adjustments), necessary for a fair presentation of
the interim period have been included. The results of the interim period is not
necessarily indicative of the results to be obtained for a full fiscal year.

of the Property. Our responsibility is to express an opinion on this financial

    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also 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 opinion.
 
    The accompanying statement of revenues and certain expenses was prepared for
the purposes of complying with the rules and regulations of the Securities and
Exchange Commission for inclusion in Form S-11 of SL Green Realty Corp., and is

To the Board of Directors of
SL Green Realty Corp.
 
    We have audited the statement of revenues and certain expenses of the
property at 440 Ninth Avenue, as described in Note 1, for the year ended
December 31, 1997. The financial statement is the responsibility of management
of the Property. Our responsibility is to express an opinion on this financial
statement based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also 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 opinion.
 
    The accompanying statement of revenues and certain expenses was prepared for
the purposes of complying with the rules and regulations of the Securities and
Exchange Commission for inclusion in Form S-11 of SL Green Realty Corp., and is
not intended to be a complete presentation of the Property's revenues and
expenses.
 
    In our opinion, the financial statement referred to above presents fairly,
in all material respects, the revenues and certain expenses of the Property, as
described in Note 1 for the year ended December 31, 1997 in conformity with
generally accepted accounting principles.

1. BASIS OF PRESENTATION
 
    Presented herein is the statement of revenues and certain expenses related
to the operations of the property located at 440 Ninth Avenue in New York City,
(the "Property").
 
    The accompanying financial statement 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 financial
statement excludes certain expenses that may not be comparable to those expected
to be incurred by SL Green Realty Corp., in the proposed future operations of
the Property. Items excluded consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statement 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 the
amounts recognized amounted to approximately $68 for the year ended December 31,
1997.
 
4. CONCENTRATION OF REVENUE
 
    Approximately 39% of the Property's revenue for the year ended December 31,
1997 was derived from three tenants.
 
5. MANAGEMENT AGREEMENTS
 
    During 1997 the Property was managed by Murray Hill Property Management,
Inc., (the "Management Company"), a related party. During the year ended
December 31, 1997 the management fees were based on 5% of gross cash receipts.
The management fee was $256 for the year ended December 31, 1997. In addition,
the Property paid to the Management Company fees of $8 for accounting services
provided by the Management Company.
 
6. RELATED PARTY TRANSACTIONS
 
    The Management Company leased office space at the Property for the year
ended December 31, 1997. The rental income of $95 was not billed to the
Management Company; however, it was partially offset by payments of $28 made by
the Management Company on behalf of the Property. The financial statement
reflects both the rental income and the expenses.

7. INSURANCE COSTS
 
    The Property is included in an umbrella insurance policy that covers several
properties managed by the Management Company. The Management Company allocates
the costs of the policy on a per square foot basis.
 
8. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with term
expiration dates ranging from 1998 to 2009. 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, 1997
(exclusive of renewal option periods) are as follows:

    We have audited the statement of revenues and certain expenses of the

December 31, 1997. The financial statement is the responsibility of management
of the Property. Our responsibility is to express an opinion on this financial
statement based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also 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 opinion.
 
    The accompanying statement of revenues and certain expenses was prepared for
the purposes of complying with the rules and regulations of the Securities and
Exchange Commission for inclusion in Form S-11 of SL Green Realty Corp., and is
not intended to be a complete presentation of the Property's revenues and
expenses.
 
    In our opinion, the financial statement referred to above presents fairly,
in all material respects, the revenues and certain expenses of the Property, as
described in Note 1 for the year ended December 31, 1997 in conformity with
generally accepted accounting principles.

    The accompanying financial statement 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 financial

to be incurred by SL Green Realty Corp., in the proposed future operations of
the Property. Items excluded consist of interest, amortization and depreciation.
 
2. USE OF ESTIMATES

assumptions that effect the amounts reported in the financial statement and
accompanying notes. Actual results could differ from those estimates.

    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

    During 1997 the Property was managed by Murray Hill Property Management,
Inc., (the "Management Company"), a related party. During the year ended

The management fee was $59 for the year ended December 31, 1997.

    The Property is included in an umbrella insurance policy that covers several
properties managed by the Management Company. The Management Company allocates
the costs of the policy on a per square foot basis.
 
7. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with term
expiration dates ranging from 1998 to 2009. 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.

    The Property is comprised of a triple net ground lease with a term expiring
in July 2033, (the "Ground Lease"). In addition, the Ground Lease contains five
ten year renewal options and requires fixed annual rent of approximately $1,550.
The rent is re-set at July 2001, July 2011 and July 2021 (and at the
commencement of each of the five ten year renewal option periods), at the
greater of (a) the net annual rental payable for the immediately preceding lease
year, or (b) 7.75% of the fair market value of the land.
 
    The ground rent may be adjusted for future periods due to the anticipated
acquisition of the Property (as described in Note 1) by SL Green.
 
8. BENEFIT PLANS
 
    The Property employees are covered by multi-employer defined benefit pension
plans and post-retirement health and welfare plans. Contributions to these plans
amounted to $101 for the year ended December 31, 1997.
 
9. LEASE AGREEMENTS
 
    The Property is being subleased to tenants under operating leases with term
expiration dates ranging from 1998 to 2011. 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, 1997
(exclusive of renewal option periods) are as follows:

ITEM 31. SALES TO SPECIAL PARTIES
 
    See Item 32.
 
ITEM 32. RECENT SALES OF UNREGISTERED SECURITIES
 
    Upon formation of the Registrant, Stephen L. Green was issued 1,000 shares
of Common Stock for total consideration of $1,000 in cash in order to provide
the initial capitalization of the Registrant. These shares will be repurchased
by the Registrant at cost upon completion of the Offering. In connection with
the Formation Transactions, certain officers of the Registrant were issued an
aggregate of 553,616 shares of Common Stock for total consideration of $3,831 in
cash. The issuance of securities described in this Item 32 were made in reliance
upon the exemption from registration provided by Section 4(2) under the
Securities Act of 1933.
 
ITEM 33. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's officers and directors are and will be indemnified under
Maryland and Delaware law, the Charter and Bylaws of the Company and the
Partnership Agreement of the Operating Partnership against certain liabilities.
The Company's Charter requires the Company to indemnify its directors and
officers to the fullest extent permitted from time to time under Maryland law.
 
    The Company's Bylaws require it to indemnify (a) any present or former
director or officer who has been successful, on the merits or otherwise, in the
defense of a proceeding to which he was made a party by reason of his service in
that capacity, against reasonable expenses incurred by him in connection with
the proceeding and (b) any present or former director or officer against any
claim or liability unless it is established that (i) his act or omission was
committed in bad faith or was the result of active or deliberate dishonesty,
(ii) he actually received an improper personal benefit in money, property or
services or (iii) in the case of a criminal proceeding, he had reasonable cause
to believe that his act or omission was unlawful.
 
    In addition, the Company's Bylaws require the Company to pay or reimburse,
in advance of final disposition of a proceeding, reasonable expenses incurred by
a present or former director or officer made a party to a proceeding by reason
of his service as a director or officer provided that the Company shall have
received (i) a written affirmation by the director or officer of his good faith
belief that he has met the standard of conduct necessary for indemnification by
the Company as authorized by the Bylaws and (ii) a written understanding by or
on his behalf to repay the amount paid or reimbursed by the Company if it
 
                                      II-1
<PAGE>
shall ultimately be determined that the standard of conduct was not met. The
Bylaws also (i) permit the Company to provide indemnification and advance
expenses to a present or former director or officer who served a predecessor of
the Company in such capacity, and to any employee or agent of the Company or a
predecessor of the Company, (ii) provide that any indemnification or payment or
reimbursement of the expenses permitted or reimbursement of expenses under
Section 2-418 of the MGCL for directors of Maryland corporations and (iii)
permit the Company to provide such other and further indemnification or payment
or reimbursement of expenses as may be permitted by Section 2-418 of the MGCL
for directors of Maryland corporations.
 
    Under Maryland law, a corporation formed in Maryland is permitted to limit,
by provision in its charter, the liability of directors and officers so that no
director of officer of the Company shall be liable to the Company or to any
stockholder for money damages except to the extent that (i) the director or
officer actually received an improper benefit in money, property or services,
for the amount of the benefit or profit in money, property or services actually
received, or (ii) a judgment or other final adjudication adverse to the director
or officer is entered in a proceeding based on a finding in a proceeding that
the director's or officer's action was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding. The Charter has incorporated the provisions of such law limiting the
liability of directors and officers.
 
    The Partnership Agreement also provides for indemnification of the Company
and its officers and directors to the same extent indemnification is provided to
officers and directors of the Company in its organizational documents, and
limits the liability of the Company and its officers and directors to the
Operating Partnership and its partners to the same extent liability of officers
and directors of the Company to the Company and its stockholders is limited
under their organizational documents.

    497(h) under the Securities Act shall be deemed to be part of the
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.
 
        (3) The undersigned registrant hereby undertakes to provide to the
    underwriter at the closing specified in the underwriting agreements
    certificates in such denominations and registered in such names as required
    by the underwriter to permit prompt delivery of each purchaser.
 
        (4) Insofar as indemnification for liabilities arising under the
    Securities Act may be permitted to directors, officers and controlling
    persons of the registrant pursuant to the foregoing provisions, or
    otherwise, the registrant has been advised that in the opinion of the
    Commission such indemnification is against public policy as expressed in the
    Securities Act and is, therefore, unenforceable. In the event that a claim
    for indemnification against such liabilities (other than the payment by the
    registrant of expenses incurred or paid by a director, officer or
    controlling person of the registrant in the successful defense of any
    action, suit or proceeding) is asserted by such director, officer or
    controlling person in connection with the securities being registered, the
    registrant will, unless in the opinion of its counsel the matter has been
    settled by controlling precedent, submit to a court of appropriate
    jurisdiction the question whether such indemnification by it is against
    public policy as expressed in the Securities Act and will be governed by the
    final adjudication of such issue.

          The Transaction Entities understand that the Underwriters propose to

after the Registration Statement (as hereinafter defined) becomes effective and
this Agreement has been executed and delivered.

          1.   REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE TRANSACTION
ENTITIES.  Each of the Transaction Entities, jointly and severally, represents,
warrants and agrees that, as of the date hereof:

               (a)  A registration statement on Form S-11 (No. 333-50311), and
     any amendments thereto, with respect to the Shares has (i) been prepared by
     the Company in conformity with the requirements of the United States
     Securities Act of 1933, as amended (the "SECURITIES ACT") and the rules and
     regulations (the "RULES AND REGULATIONS") of the United States Securities
     and Exchange Commission (the "COMMISSION") thereunder, (ii) been filed with
     the Commission under the Securities Act and (iii) become effective under
     the Securities Act.  Copies of such registration statement and any
     amendments thereto have been delivered by the Company to you as the
     Underwriters.  As used in this Agreement, "EFFECTIVE TIME" means the date
     and the time as of which such registration statement, or the most recent
     post-effective amendment thereto, if any, was declared effective by the
     Commission; "EFFECTIVE DATE" means the date of the Effective Time;
     "PRELIMINARY PROSPECTUS" means each prospectus included in such
     registration statement, or amendments thereto, before it became effective
     under the Securities Act and any prospectus filed with the Commission by
     the Company with the consent of the Underwriters pursuant to Rule 424(a) of
     the Rules and Regulations; "REGISTRATION STATEMENT" means such registration
     statement, as amended at the Effective Time, including all information
     contained in the final prospectus filed with the Commission pursuant to
     Rule 424(b) of the Rules and Regulations and deemed to be a part of the
     registration statement as of the Effective Time pursuant to paragraph
     (b) of Rule 430A of the Rules and Regulations; and "PROSPECTUS" means such
     final prospectus, as first filed with the Commission pursuant to paragraph
     (1) or (4) of Rule 424(b) of the Rules and Regulations.  Any registration
     statement (including any amendment or supplement thereto or information
     which is deemed to be a part thereof) filed by the Company to register
     additional Series A Preferred Shares under Rule 462(b) of the Rules and
     Regulations ("RULE 462(B) REGISTRATION STATEMENT") shall be deemed a part
     of the Registration Statement.  Any prospectus (including any amendment or
     supplement thereto or information which is deemed to be a part thereof)
     included in a Rule 462(b) Registration Statement shall be deemed to be part
     of the Prospectus.  If a Rule 462(b) Registration Statement is filed in
     connection with the offering and sale of the Shares, the Company will have
     complied or will comply with the requirements of Rule 111 under the
     Securities Act relating to the payment of filing fees therefor.  The
     Company has not

<PAGE>

     distributed, and prior to the later of the Closing Date and the completion
     of the distribution of the Shares, will not distribute, any offering
     material in connection with the offering or sale of the Shares other than
     the Registration Statement, the Preliminary Prospectus (as hereinafter
     defined), the Prospectus or any other materials, if any, permitted by the
     Securities Act (which were disclosed to the Underwriters and Underwriters'
     counsel).  For purposes of this Agreement, all references to the
     Registration Statement, any Preliminary Prospectus or the Prospectus or any
     amendment or supplement to any of the foregoing shall be deemed to include
     the copy filed with the Commission pursuant to its Electronic Data
     Gathering, Analysis and Retrieval system ("EDGAR").


               (b)  Each Preliminary Prospectus included as part of the
     Registration Statement as originally filed or as part of any amendment or
     supplement thereto, or filed pursuant to Rule 424 under the Securities Act
     and the Rules and Regulations, complied when so filed in all material
     respects with the provisions of the Securities Act.  The Commission has not
     issued any order preventing or suspending the use of any Preliminary
     Prospectus.

               (c)  The Registration Statement conforms, and the Prospectus and
     any further amendments or supplements to the Registration Statement or the
     Prospectus will, when they become effective or are filed with the
     Commission, as the case may be, conform in all material respects to the
     requirements of the Securities Act and the Rules and Regulations and do not
     and will not, as of the applicable Effective Date (as to the Registration
     Statement and any amendment thereto) and as of the applicable filing date
     and at the First Delivery Date (as hereinafter defined) (as to the
     Prospectus and any amendment or supplement thereto) contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading (with respect to the Prospectus, in light of the circumstances
     under which they were made); PROVIDED that no representation or warranty is
     made as to information contained in or omitted from the Registration
     Statement or the Prospectus in reliance upon and in conformity with written
     information furnished to the Company by or on behalf of any Underwriter
     specifically for inclusion therein.  The Prospectus delivered to the
     Underwriters for use in connection with the offering of Shares will, at the
     time of such delivery, be identical to the electronically transmitted
     copies thereof filed with the Commission pursuant to EDGAR, except to the
     extent permitted by Regulation S-T.

               (d)  No stop order suspending the effectiveness of the
     Registration Statement or any part thereof has been issued and no
     proceeding for that purpose has been instituted or, to the knowledge of any
     of the Transaction Entities, threatened by the Commission or by the state
     securities authority of any jurisdiction.  No order preventing or
     suspending the use of any Preliminary Prospectus or the Prospectus has been
     issued and no proceeding for that purpose has been instituted or, to the
     knowledge of any of the Transaction Entities, threatened by the Commission
     or by the state securities authority of any jurisdiction.

               (e)  The Company has been duly formed and is validly existing as
     a corporation in good standing under the laws of the State of Maryland, is
     duly qualified to do business and is in good standing as a foreign
     corporation in each jurisdiction in which its ownership or lease of
     property and other assets or the conduct of its business requires such
     qualification, except where the failure to so qualify will not have a
     material adverse effect on the business, prospects, operations, management,
     consolidated financial position, net worth, stockholders' equity or results
     of operations of the Transaction Entities considered as one enterprise or
     on the use or value of the Properties (as hereinafter defined),
     collectively (a "MATERIAL ADVERSE EFFECT"), and has all power and authority
     necessary to own or hold its properties and other assets, to conduct the
     business in which it is engaged and to enter into and perform its
     obligations under this Agreement and the other Operative Documents (as
     hereinafter defined) to which it is a party.  None of the subsidiaries of
     the Company (other than the Operating Partnership, the Management
     Corporation, the Management LLC, the Leasing Corporation and Construction
     Corporation) is a "SIGNIFICANT SUBSIDIARY," as such term is defined in
     Rule 405 of the Rules and Regulations.  Except as described in the
     Prospectus, the Company owns no direct or indirect equity interest in any
     entity other than the Transaction Entities.

               (f)  The Company has an authorized capitalization as set forth in
     the Prospectus.  Except as disclosed in the Prospectus, (i) no Series A
     Preferred Shares are reserved for any purpose, (ii) except for the ___%
     Series A Convertible, Cumulative Preference Units of the Operating
     Partnership ("PREFERENCE UNITS") and the outstanding units of limited
     partner interest of the Operating Partnership ("UNITS"), there are no
     outstanding securities convertible into or exchangeable for any Series A
     Preferred Shares or shares of the Company's common stock, par value $.01
     per share ("COMMON STOCK"), and (iii) there are no outstanding options,
     rights (preemptive or otherwise) or warrants to purchase or subscribe for
     Series A Preferred Shares or any other securities of the Company.

               (g)  The Operating Partnership has been duly formed and is
     validly existing as a limited partnership in good standing under the laws
     of the State of Delaware, is duly qualified to do business and is in good
     standing as a foreign limited partnership in each jurisdiction in which its
     ownership or lease of property and other assets or the conduct of its
     business requires such qualification, except where the failure to so
     qualify will not have a Material Adverse Effect, and has all power and
     authority necessary to own or hold its properties and other assets, to
     conduct the business in which it is engaged and to enter into and perform
     its obligations under this Agreement and the other Operative Documents (as
     hereinafter defined) to which it is a party.  The Company is the sole
     general partner of the Operating Partnership.  The Agreement of Limited
     Partnership of the Operating Partnership, as amended (the "OPERATING
     PARTNERSHIP AGREEMENT") is in full force and effect, and the aggregate
     percentage interests of the Company and the limited partners in the
     Operating Partnership are as set forth in the Prospectus; PROVIDED that to
     the extent any portion of the over-allotment option described in Section 2
     hereof is exercised at the First Delivery Date, the percentage interest of
     such partners in the Operating Partnership will be adjusted accordingly.
     Additionally, to the extent any portion of such over-allotment option is
     exercised subsequent to the First 

                                          4
<PAGE>

     Delivery Date, the Company will contribute the proceeds from the sale of
     the Option Shares to the Operating Partnership in exchange for a number of
     Preference Units equal to the number of Option Shares issued.

               (h)  Each of the Service Corporations has been duly formed and is
     validly existing as a corporation in good standing under the laws of the
     State of New York, is duly qualified to do business and is in good standing
     as a foreign corporation in each jurisdiction in which its ownership or
     lease of property and other assets or the conduct of its business requires
     such qualification, except where the failure to so qualify would not have a
     Material Adverse Effect, and has all power and authority necessary to own
     or hold its properties and other assets, to conduct the business in which
     it is engaged and to enter into and perform its obligations under this
     Agreement and the other Operative Documents (as hereinafter defined) to
     which it is a party.  All of the issued and outstanding capital stock of
     each Service Corporation has been duly authorized and validly issued, is
     fully paid and non-assessable, has been offered and sold in compliance with
     all applicable laws (including, without limitation, federal or state
     securities laws) and, all of such capital stock owned by the Operating
     Partnership (100% of the nonvoting common stock) is owned free and clear of
     any security interest, mortgage, pledge, lien, encumbrance, claim,
     restriction or equities.  No shares of capital stock of any Service
     Corporation are reserved for any purpose, and there are no outstanding
     securities convertible into or exchangeable for any capital stock of any
     Service Corporation and no outstanding options, rights (preemptive or
     otherwise) or warrants to purchase or to subscribe for shares of such
     capital stock or any other securities of any Service Corporation.

               (i)  The Management LLC has been duly formed and is validly
     existing as a limited liability company in good standing under the laws of
     the State of Delaware, is duly qualified to do business and is in good

     which its ownership or lease of property and other assets or the conduct of
     its business requires such qualification, except where the failure to so
     qualify would not have a Material Adverse Effect, and has all power and
     authority necessary to own or hold its properties and other assets, to
     conduct the business in which it is engaged and to enter into and perform
     its obligations under this Agreement and the other Operative Documents (as
     hereinafter defined) to which it is a party.  All of the issued and
     outstanding membership interests of the Management LLC have been duly
     authorized and validly issued, are fully paid and non-assessable, have been
     offered and sold in compliance with all applicable laws (including, without

     good and marketable title to each of the interests in the Properties and
     the other assets described in the Prospectus as being owned by the

     Material Adverse Effect and all material consents or approvals with respect
     to any such transfer shall have been received; (B) all liens, charges,

     mortgages or other security documents or other agreements encumbering or
     otherwise recorded against the Properties, and no Transaction Entity knows
     of any event which, but for the passage of time or the giving of notice, or

     except with respect to (i) and (ii) immediately above any such default that
     would not have a Material Adverse Effect; (D) no tenant under any of the
     leases at the Properties has a right of first refusal to purchase the

     laws and regulations and laws relating to access to the Properties), except
     for such failures to comply that would not have a Material Adverse Effect;

     condemnation proceedings, zoning change or other proceeding or action that
     will in any material manner affect the size of, use of, improvements on,

     Statement, the Transaction Entities are insured by insurers of recognized
     financial responsibility against such losses and risks and in such amounts
     and covering such risks as are customary in the businesses in which they
     are engaged or propose to engage after giving effect to the transactions

     governmental proceedings pending to which any Transaction Entity is a party
     or of which any property or assets of any Transaction Entity is the subject
     which, if determined adversely to such Transaction Entity, might have a
     Material Adverse Effect; and to the 

                                          11
<PAGE>

     best knowledge of the Transaction Entities, no such proceedings are
     threatened or contemplated by governmental authorities or threatened by
     others.

               (z)  There are no contracts or other documents which are required
     to be described in the Prospectus or filed as exhibits to the Registration
     Statement by the Securities Act or by the Rules and Regulations which have
     not been described in the Prospectus or filed as exhibits to the
     Registration Statement or incorporated therein by reference as permitted by
     the Rules and Regulations.  Neither the Company, nor to the Company's
     knowledge, any other party is in default in the observance or performance
     of any term or obligation to be performed by it under any agreement listed
     in the exhibits to the Registration Statement, and no event has occurred
     which with notice or lapse of time or both would constitute such a default,
     in any such case which default or event would have a Material Adverse
     Effect.  No default exists, and no event has occurred which with notice or
     lapse of time or both would constitute a default, in the due performance
     and observance of any term, covenant or condition, by the Company or any of
     its subsidiaries of any other agreement or instrument to which the Company
     or any of its subsidiaries is a party or by which any of them or their
     respective properties or businesses may be bound or affected which default
     or event would have a Material Adverse Effect.

               (aa) No relationship, direct or indirect, exists between or among
     any of the Transaction Entities on the one hand, and the directors,
     officers, stockholders, customers or suppliers of the Transaction Entities
     on the other hand, which is required to be described in the Prospectus
     which is not so described.

               (bb) No labor disturbance by the employees of any Transaction
     Entity exists or, to the knowledge of the Transaction Entities, is imminent
     which might be expected to have a Material Adverse Effect.

               (cc) Each Transaction Entity is in compliance in all material
     respects with all presently applicable provisions of the Employee
     Retirement Income Security Act of 1974, as amended, including the
     regulations and published interpretations thereunder ("ERISA"); no
     "REPORTABLE EVENT" (as defined in ERISA) has occurred with respect to any
     "PENSION PLAN" (as defined in ERISA) for which any Transaction Entity would
     have any liability; no Transaction Entity has incurred or expects to incur
     liability under (i) Title IV of ERISA with respect to termination of, or
     withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the
     Code; and each "pension plan" for which any Transaction Entity would have
     any liability that is intended to be qualified under Section 401(a) of the
     Code is so qualified in all material respects and nothing has occurred,
     whether by action or by failure to act, which would cause the loss of such
     qualification, except where the failure to be so qualified would not have a
     Material Adverse Effect.

               (dd) Each Transaction Entity has filed all federal, state and
     local income and franchise tax returns required to be filed through the
     date hereof and has paid all taxes due thereon, and no tax deficiency has
     been determined adversely to any Transaction Entity which has had (nor does
     any Transaction Entity have any knowledge 

                                          12
<PAGE>

     of any tax deficiency which, if determined adversely to it might have) a
     Material Adverse Effect.

               (ee) At all times since August 14, 1997, the Company, the
     Operating Partnership, the Management LLC and the Service Corporations have
     been and upon the sale of Shares will continue to be, organized and
     operated in conformity with the requirements for qualification of the
     Company as a real estate investment trust ("REIT") under the Code and the
     proposed method of operation of the Company, the Operating Partnership, the
     Management LLC and the Service Corporations will enable the Company to
     continue to meet the requirements for qualification and taxation as a REIT
     under the Code.

     Prospectus through the date hereof, and except as may otherwise be
     disclosed in the Prospectus, (i) no Transaction Entity has (a) issued or

representations and warranties contained in, and subject to the terms and

severally and not jointly, to the several Underwriters and each of the
Underwriters, severally and not jointly, agrees to purchase the number of Firm
Shares set forth opposite that Underwriter's name in Schedule 1 hereto.  The
respective purchase obligations of the Underwriters with respect to the Firm
Shares shall be rounded among the Underwriters to avoid fractional shares, as
the Underwriters may determine.

          In addition, the Company grants to the Underwriters an option to
purchase up to 600,000 Option Shares.  Such option is granted solely for the
purpose of covering over-allotments in the sale of Firm Shares and is
exercisable as provided in Section 4 hereof.  Option Shares shall be purchased
severally for the account of the Underwriters in proportion to the number of
Firm Shares set forth opposite the name of such Underwriters in Schedule 1
hereto.  The respective purchase obligations of each Underwriter with respect to
the Option Shares shall be adjusted by the Underwriters so that no Underwriter
shall be obligated to purchase Option Shares other than in 100-share amounts. 
The price of both the Firm Shares and any Option Shares shall be $[_____] per
share.

delivered on the First Delivery Date or the Second Delivery Date (as hereinafter

purchased on such Delivery Date as provided herein.

          3.   OFFERING OF SHARES BY THE UNDERWRITERS.

Shares, the Underwriters propose to offer the Firm Shares for sale upon the
terms and conditions set forth in the Prospectus.

          4.   DELIVERY OF AND PAYMENT FOR THE SHARES.  Delivery of and payment

determined by agreement between the Underwriters and the Company, at 10:00 A.M.,
New York City time, on the third full business day following the date of this
Agreement or on the fourth full business day if the Agreement is executed after

transfer of same-day funds.  Time shall be of the essence, and delivery at the
time and place specified pursuant to this Agreement is a further condition of
the obligation of each Underwriter hereunder.  Upon delivery, the Firm Shares

Agreement, the option granted in Section 2 may be exercised, in whole or in
part, from time to time, by written notice being given to the Company by the
Underwriters.  Such notice shall set forth the aggregate number of Option Shares
as to which the option is being exercised, the names in which the Option Shares
are to be registered, the denominations in which the Option Shares are to be
issued and the date and time, as determined by the Underwriters, when the Option
Shares are to be delivered; PROVIDED, HOWEVER, that this date and time shall not
be earlier than the First Delivery Date nor earlier than the second business day
after the date on which the option shall have been exercised nor later than the
fifth business day after the date on which the option shall have been exercised.
The date and time the Option Shares are delivered are sometimes referred to as
the "SECOND DELIVERY DATE" and the First Delivery Date and the Second Delivery

<PAGE>

          of operation of the Company will enable the Company to continue to
          meet the requirements for qualification and taxation as a REIT under
          the Code and the Operating Partnership is classified as a partnership

          "publicly traded partnership" taxable as a corporation under
          Section 7704(a) of the Code.

                    (xvi)     No Transaction Entity is an "investment company"
          within the meaning of such term under the Investment Company Act of
          1940, as amended and the rules and regulations of the Commission
          thereunder.  The Series A Preferred Shares have been approved for
          listing on the NYSE upon notice of issuance.

                    (xvii)    The Registration Statement was declared effective

          of such counsel, no stop order suspending the effectiveness of the
          Registration Statement has been issued and, to the best knowledge of
          such counsel, no proceeding for that purpose is pending or threatened

          prior to such Delivery Date (other than the financial statements and
          related schedules and other financial and statistical data included
          therein, as to which such counsel need express no opinion) comply as
          to form in all material respects with the requirements of the
          Securities Act and the Rules and Regulations. 

                    (xix)     The statements contained in the Prospectus under
          the captions "Capital Stock," "Certain Provisions of Maryland Law and
          the Company's Charter and Bylaws," "Shares Available for Future Sale,"
          "Partnership Agreement," and "Material Federal Income Tax
          Consequences," insofar as those statements are descriptions of
          contracts, agreements or other legal documents, or they describe
          federal statutes, rules and regulations or legal conclusions,
          constitute a fair summary thereof, and the opinion of such counsel
          filed as Exhibit 8 to the Registration Statement is confirmed and the
          Underwriters may rely upon such opinion as if it were addressed to
          them.

     In rendering such opinion, such counsel may (i) state that its opinion is
     limited to matters governed by the Federal laws of the United States of
     America and the States of Delaware, Maryland and New York; (ii) rely (to
     the extent such counsel deems proper and specifies in their opinion), as to
     matters involving the application of the laws of the States of Maryland and
     Delaware upon the opinion of other counsel of good standing, PROVIDED that
     such other counsel is reasonably satisfactory to counsel for the
     Underwriters and furnishes a copy of its opinion to the Underwriters; (iii)
     in respect of matters of fact, upon certificates of officers of the Company
     or its subsidiaries, PROVIDED that such counsel shall state that it
     believes that both the Underwriters and it are justified 

                                          25

     connection with the preparation of the Registration Statement and the
     Prospectus, and (y) based on the foregoing, no facts have come to the
     attention of such counsel which lead it to believe that the Registration
     Statement, as of the Effective Date, contained any untrue statement of a
     material fact or omitted to state a material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading, or that the Prospectus contains any untrue statement of a
     material fact or omits to state a material fact necessary in order to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading.  The foregoing opinion and statement may be qualified
     by a statement to the effect that such counsel does not assume any
     responsibility for the accuracy, completeness or fairness of the statements
     contained in the Registration Statement or the Prospectus  and may state
     that such counsel expresses no belief with respect to the financial
     statements and notes thereto and other financial and statistical data
     included in the Registration Statement or the Prospectus.  

               (e)  The Underwriters shall have received from Rogers & Wells

          counsel for the Underwriters, dated such Date of Delivery, relating to
          the Option Shares to be purchased on such Date of Delivery and
          otherwise to the same effect as the opinions required by
          Section 7(d) hereof.

                    (iii)  The favorable opinion of Rogers & Wells LLP, counsel
          for the Underwriters, dated such Date of Delivery, relating to the
          Option Shares to be purchased on such Date of Delivery and otherwise
          to the same effect as the opinion required by Section 7(e) hereof.

                    (iv)   A letter from Ernst & Young LLP, in form and
          substance satisfactory to the Underwriters and dated such Date of
          Delivery, substantially the same in form and substance as the letters
          furnished to the Underwriters pursuant to Sections 7(f) and (g)
          hereof.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

          Any certificate or document signed by any officer of the Transaction
Entities and delivered to the Underwriters, or to counsel for the Underwriters,
shall be deemed a representation and warranty by the Transaction Entities to
each Underwriter as to the statements made therein.

          The several obligations of the Underwriters to purchase Option Shares
hereunder are subject to the satisfaction on and as of any Date of Delivery of
the conditions set forth in this Section 7, except that, if any Date of Delivery
is other than the First Delivery Date, the certificates, opinions and letters
referred to in Sections 7(d) through 7(i) hereof shall be dated the Date of
Delivery in question and the opinions called for by Sections 7(d) and
7(e) hereof shall be revised to reflect the sale of Option Shares.

          8.   EFFECTIVE DATE OF AGREEMENT.

          This Agreement shall become effective:  (i) upon the execution hereof
by the parties hereto; or (ii) if, at the time this Agreement is executed and
delivered, it is necessary for the Registration Statement or a post-effective
amendment thereto to be declared effective before 

                                          28
<PAGE>

the offering of the Shares may commence, when notification of the effectiveness
of the Registration Statement or such post-effective amendment has been released
by the Commission.

          9.   DEFAULT BY ONE OR MORE OF THE UNDERWRITERS.

          If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Shares which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of Firm Shares set forth opposite
the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears
to the total number of Firm Shares set forth opposite the names of all the
remaining non-defaulting Underwriters in Schedule 1 hereto; PROVIDED, HOWEVER,
that the remaining non-defaulting Underwriters shall not be obligated to
purchase any of the Shares on such Delivery Date if the total number of Shares
which the defaulting Underwriter or Underwriters agreed but failed to purchase
on such date exceeds 9.09% of the total number of Shares to be purchased on such
Delivery Date, and any remaining non-defaulting Underwriter shall not be
obligated to purchase more than 110% of the number of Shares which it agreed to
purchase on such Delivery Date pursuant to the terms of Section 2.  If the
foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or
those other underwriters satisfactory to the Underwriters who so agree, shall
have the right, but shall not be obligated, to purchase, in such proportion as
may be agreed upon among them, all the Shares to be purchased on such Delivery
Date.  If the remaining Underwriters or other underwriters satisfactory to the
Underwriters do not elect to purchase the Shares which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such Delivery Date,
this Agreement (or, with respect to the Second Delivery Date, the obligation of
the Underwriters to purchase, and of the Company to sell, the Option Shares)
shall terminate without liability on the part of any non-defaulting Underwriter
or the Transaction Entities, except that the Transaction Entities will continue
to be liable for the payment of expenses to the extent set forth in Sections 6
and 13.  As used in this Agreement, the term "Underwriter" includes, for all
purposes of this Agreement unless the context requires otherwise, any party not
listed in Schedule 1 hereto who, pursuant to this Section 9, purchases Firm
Shares which a defaulting Underwriter agreed but failed to purchase.

          Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Transaction Entities for damages caused by its
default.  If other underwriters are obligated or agree to purchase the Shares of
a defaulting or withdrawing Underwriter, either the Underwriters or the Company
may postpone the Delivery Date for up to seven full business days in order to
effect any changes that in the opinion of counsel for the Company or counsel for
the Underwriters may be necessary in the Registration Statement, the Prospectus
or in any other document or arrangement.

          10.  INDEPENDENT UNDERWRITER.

          (a)  Although the Conduct Rules of the NASD exempts REITs from the
conflict of interest provisions thereof, because Lehman Brothers Inc. and
certain of its affiliates will receive more than 10% of the net proceeds of the
Offering in payment of the Acquisition Facility, the Underwriters have
determined to conduct the Offering in accordance with the applicable provisions
of Rule 2720 of the Conduct Rules ("RULE 2720").  In accordance with 

                                          29
<PAGE>

these requirements, the Company hereby confirms its engagement, without
compensation, of the services of Prudential Securities Incorporated as, and
Prudential Securities Incorporated hereby confirms its agreement with the
Company to render services as, a "qualified independent underwriter" (in such
capacity, the "Independent Underwriter") within the meaning of Rule 2720 of the
NASD with respect to the offering and sale of the Securities.

          (b)  The Independent Underwriter hereby represents and warrants to,
and agrees with, the Company and Lehman Brothers Inc. that with respect to the
offering and sale of Securities as described in the Prospectus:

                    (i)    the Independent Underwriter is a "qualified
          independent underwriter" within the meaning of Rule 2720; 

                    (ii)   the Independent Underwriter has participated in the
          preparation of the Registration Statement and the Prospectus and has
          exercised the usual standards of "due diligence" with respect thereto;

                    (iii)  the Independent Underwriter has undertaken the legal
          responsibilities and liabilities of an underwriter under the
          Securities Act, including those contained in Section 11 thereof,
          subject to the limitations on such liabilities set forth herein.  It
          is specifically understood, however, that Prudential Securities
          Incorporated will bear such legal responsibilities and liabilities
          only to the extent, if any, that a court of competent jurisdiction
          rules in a judgment which has become final, and not subject to further
          appeal, that Prudential Securities Incorporated, as Independent
          Underwriter, bears the legal responsibilities and liabilities of an
          "underwriter"; 

                    (iv)   based upon, among other factors, the information set
          forth in the Preliminary Prospectus and its review of such other
          documents and the taking of such other actions as the Independent
          Underwriter, in its sole discretion, has deemed necessary or
          appropriate for the purposes of delivering its recommendation
          hereunder, the Independent Underwriter recommends, as of the date of
          the execution and delivery of this Agreement, that the public offering
          price for the Securities not exceed the amount of $[____] per share,
          which price should in no way be considered or relied upon except as
          set forth therein and in the letter referred to in clause (v) below;
          and 

                    (v)    the Independent Underwriter will furnish to the
          other Underwriters on the date hereof a letter, dated the date hereof,
          substantially to the effect set forth in Schedule 2 hereto.

          (c)  The Company, the Independent Underwriter and the other
Underwriters agree to comply in all material respects with all of the
requirements of Rule 2720 applicable to them in connection with the offering and
sale of the Securities.  The Company agrees to cooperate with the Underwriters
to enable the Underwriters to comply with Rule 2720 and the Independent
Underwriter to perform the services contemplated by this Agreement.

                                          30
<PAGE>

          (d)  The Independent Underwriter hereby consents to the references to
it as set forth under the caption "Underwriting" in the Prospectus.

          11.  INDEMNIFICATION AND CONTRIBUTION.

          (a)  The Transaction Entities jointly and severally, shall indemnify
and hold harmless each Underwriter, its officers and employees and each person,
if any, who controls any Underwriter within the meaning of the Securities Act,
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to purchases and sales of Shares), to which
that Underwriter, officer, employee or controlling person may become subject,
under the Securities Act or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained (a) in any Preliminary
Prospectus, the Registration Statement or the Prospectus or in any amendment or
supplement thereto or (b) in any blue sky application or other document prepared
or executed by the Company (or based upon any written information furnished by
the Company) specifically for the purpose of qualifying any or all of the Shares
under the securities laws of any state or other jurisdiction (any such
application, document or information being hereinafter called a "Blue Sky
Application"), (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or in any amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading
(with respect to the Prospectus, in light of the circumstances under which they
were made) or (iii) any act or failure to act or any alleged act or failure to
act by any Underwriter in connection with, or relating in any manner to, the
Shares or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising out of or
based upon matters covered by clause (i) or (ii) above (PROVIDED that the
Transaction Entities shall not be liable under this clause (iii) to the extent
that it is determined in a final judgment by a court of competent jurisdiction
that such loss, claim, damage, liability or action resulted directly from any
such acts or failures to act undertaken or omitted to be taken by such
Underwriter through its gross negligence or willful misconduct), and shall
reimburse each Underwriter and each such officer, employee or controlling person
promptly upon demand for any legal or other expenses reasonably incurred by that
Underwriter, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; PROVIDED, HOWEVER,
that the Transaction Entities shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or action arises out of, or is
based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus, or in any such amendment or supplement, or in any Blue Sky
Application, in reliance upon and in conformity with written information
concerning such Underwriter furnished to the Company through the Underwriters by
or on behalf of any Underwriter specifically for inclusion therein.  The
foregoing indemnity agreement is in addition to any liability which the
Transaction Entities may otherwise have to any Underwriter or to any officer,
employee or controlling person of that Underwriter.

          (b)  Each Underwriter, severally and not jointly, shall indemnify and
hold harmless each Transaction Entity, its officers and employees, each of its
directors (including any 

                                          31
<PAGE>

person who, with his consent, is named in the Registration Statement as about to
become a director of the Company), and each person, if any, who controls each
Transaction Entity within the meaning of the Securities Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which each Transaction Entity or any such director, officer or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in any Preliminary Prospectus, the Registration Statement or
the Prospectus or in any amendment or supplement thereto, or (B) in any Blue Sky
Application or (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or in any amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading,
but in each case only to the extent that the untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information concerning such Underwriter furnished to the
Company through the Underwriters by or on behalf of that Underwriter
specifically for inclusion therein, and shall reimburse each Transaction Entity
and any such director, officer or controlling person for any legal or other
expenses reasonably incurred by each Transaction Entity or any such director,
officer or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are incurred.  The foregoing indemnity agreement is in addition to
any liability which any Underwriter may otherwise have to each Transaction
Entity or any such director, officer, employee or controlling person.

          (c)  The Company also agrees to indemnify and hold harmless Prudential
Securities Incorporated and each person, if any, who controls Prudential
Securities Incorporated within the meaning of either Section 15 of the Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages, liabilities and judgments incurred as a result of Prudential Securities
Incorporated's participation as a "qualified independent underwriter" within the
meaning of Rule 2720 in connection with the offering of the Securities, except
for any losses, claims, damages, liabilities and judgments resulting from
Prudential Securities Incorporated's, or such controlling person's, willful
misconduct or gross negligence.

          (d)  Promptly after receipt by an indemnified party under this
Section 11 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 11, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 11 except to the extent it has
been materially prejudiced by such failure and, PROVIDED FURTHER, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 11. 
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this Section 11 for any legal or other expenses
subsequently incurred 

                                          32
<PAGE>

by the indemnified party in connection with the defense thereof other than
reasonable costs of investigation; PROVIDED, HOWEVER, that the Underwriters
shall have the right to employ counsel to represent jointly the Underwriters and
those other Underwriters and their respective officers, employees and
controlling persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the Underwriters against the
Transaction Entities under this Section 11 if, in the reasonable judgment of the
Underwriters, it is advisable for the Underwriters and those Underwriters,
officers, employees and controlling persons to be jointly represented by
separate counsel, and in that event the fees and expenses of such separate
counsel shall be paid by the indemnifying party.  No indemnifying party shall
(i) without the prior written consent of the indemnified parties (which consent
shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment of the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

          (e)  If the indemnification provided for in this Section 11 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 11(a) or 11(d) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Transaction Entities on the one hand and the Underwriters on the
other from the offering of the Shares or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Transaction Entities on the one hand
and the Underwriters on the other with respect to the statements or omissions
which resulted in such loss, claim, damage or liability, or action in respect
thereof, as well as any other relevant equitable considerations.  The relative
benefits received by the Transaction Entities on the one hand and the
Underwriters on the other with respect to such offering shall be deemed to be in
the same proportion as the total net proceeds from the offering of the Shares
purchased under this Agreement (before deducting expenses) received by the
Transaction Entities, on the one hand, and the total underwriting discounts and
commissions received by the Underwriters with respect to the Shares purchased
under this Agreement, on the other hand, bear to the total gross proceeds from
the offering of the Shares under this Agreement, in each case as set forth in
the table on the cover page of the Prospectus.  The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Transaction Entities or the Underwriters, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission.  The Transaction
Entities and the Underwriters agree that it would not be just and equitable if
contributions pursuant to this Section were to be determined by pro rata 

                                          33
<PAGE>

allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein.  The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section shall be deemed to
include, for purposes of this Section 11(e), any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.  Notwithstanding the provisions of this
Section 11(e), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by it and distributed to the public was offered to the public exceeds the amount
of any damages which such Underwriter has otherwise paid or become liable to pay
by reason of any untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  The
Underwriters' obligations to contribute as provided in this Section 11(e) are
several in proportion to their respective underwriting obligations and not
joint.

          (f)  The Underwriters severally confirm and each Transaction Entity
acknowledges that (i) the statements with respect to the public offering of the
Shares by the Underwriters set forth on the cover page of, (ii) the legend
concerning over-allotments on the inside front cover page of and (iii) the names
of the Underwriters and the number of Shares which they are each purchasing, the
concession and reallowance figures and the information contained in the third,
ninth, tenth, eleventh, twelfth, thirteenth, fourteenth and fifteenth
paragraphs, in each case appearing under the caption "Underwriting" in, the
Prospectus are correct and constitute the only information concerning such
Underwriters furnished in writing to the Company by or on behalf of the
Underwriters specifically for inclusion in the Registration Statement and the
Prospectus.

          12.  TERMINATION.  The obligations of the Underwriters hereunder may
be terminated by the Underwriters by notice given to and received by the Company
prior to delivery of and payment for the Firm Shares if, prior to that time, any
of the following events shall have occurred or if the Underwriters shall decline
to purchase the Shares for any reason permitted under this Agreement:

               (a)(i) Any of the Transaction Entities or any Property shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, otherwise than as set forth or contemplated in the Prospectus or
     (ii) since such date there shall have been any change in the capital stock
     or long-term debt of any Transaction Entity or any change, or any
     development involving a prospective change, in or affecting any Property or
     the general affairs, management, financial position, stockholders' equity
     or results of operations of any Transaction Entity, otherwise than as set
     forth or contemplated in the Prospectus, the effect of which, in any such
     case described in clause (i) or (ii), is, in the judgment of the
     Underwriters, so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Shares being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus;

                                          34
<PAGE>

               (b)  Subsequent to the execution and delivery of this Agreement
     there shall have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of a majority in interest of the several Underwriters, impracticable or
     inadvisable to proceed with the public offering or delivery of the Shares
     being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus; or

               (c)  The Transaction Entities shall have failed at or prior to
     such Delivery Date to have performed or complied with any of their
     agreements herein contained and required to be performed or complied with
     by them hereunder at or prior to such Delivery Date.

          13.  REIMBURSEMENT OF UNDERWRITERS' EXPENSES.  The Company shall
reimburse the Underwriters in an amount equal to $40,000 for legal expenses.  If
(a) the Company shall fail to tender the Shares for delivery to the Underwriters
by reason of any failure, refusal or inability on the part of the Transaction
Entities to perform any agreement on their part to be performed, or because any
condition specified in Sections 12(a) and (c) hereof required to be fulfilled by
the Transaction Entities is not fulfilled, the Transaction Entities will
reimburse the Underwriters for all reasonable out-of-pocket expenses (including
fees and disbursements of counsel) incurred by the Underwriters in connection
with this Agreement and the proposed purchase of the Shares, and upon demand the
Transaction Entities shall pay the full amount thereof to the Underwriters.  If
this Agreement is terminated pursuant to Section 12(b) or pursuant to Section 9
by reason of the default of one or more Underwriters, the Transaction Entities
shall not be obligated to reimburse any defaulting Underwriter on account of
those expenses.

          14.  NOTICES, ETC.  All statements, requests, notices and agreements
hereunder shall be in writing, and:

               (a)  if to the Underwriters, shall be delivered or sent by mail,
     telex or facsimile transmission to Lehman Brothers Inc., Three World
     Financial Center, New York, New York 10285, Attention:  Syndicate

Section 11(d) shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its acceptance
telex to the Underwriters, which address will be supplied to any other party
hereto by the Underwriters upon request.  Any such statements, requests, notices
or agreements shall take effect at the time of receipt thereof.  The Transaction
Entities shall be entitled to act and rely upon any request, consent, notice or
agreement given or made on behalf of the Underwriters by Lehman Brothers Inc.

          15.  PERSONS ENTITLED TO BENEFIT OF AGREEMENT.  This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Transaction
Entities, and their respective personal representatives and successors.  This
Agreement and the terms and provisions hereof are for the sole benefit of only
those persons, except that (a) the representations, warranties, indemnities and
agreements of the Transaction Entities contained in this Agreement shall also be
deemed to be for the benefit of the person or persons, if any, who control any
Underwriter within the meaning of Section 15 of the Securities Act and (b) the
indemnity agreement of the Underwriters contained in Section 11(c) of this
Agreement shall be deemed to be for the benefit of directors of the Transaction
Entities, officers of the Company who have signed the Registration Statement and

New York, New York  10018

                                   PRICING OPINION

Ladies and Gentlemen:

SL Green Realty Corp., a Maryland corporation (the "COMPANY"), has filed with
the Securities and Exchange Commission a registration statement on Form S-11
(Reg. No. 333-50311) relating to the offering of 4,000,000 shares of ___%
Preferred Income Equity Redeemable SharesSM ("PIERS-SM-") (plus up to 600,000
shares of PIERS subject to the underwriters' over-allotment option), par value
$.01 per share (the "PREFERRED STOCK").

Lehman Brothers Inc. ("LEHMAN") is acting as the other underwriter of the
offering to the public of the Preferred Stock (the "OFFERING").  In connection
with the Offering an affiliate of Lehman will receive $240 million in net
proceeds in repayment of amounts outstanding under a loan made to the Company. 
As a result, an affiliate of Lehman, will receive more than 10% of the proceeds
of the Offering.

Although the Conduct Rules of the NASD exempt REITs from the conflict of
interest provisions thereof, because Lehman and certain of its affiliates will
receive more than 10% of the net proceeds of the Offering, the underwriters have
determined to conduct the Offering in accordance with the applicable provisions
of Rule 2720 of the Conduct Rules.   Accordingly, the public offering price can
be no higher than that recommended by a "qualified independent underwriter"
meeting certain standards.

We have been retained as a Qualified Independent Underwriter to recommend to you
the maximum offering price for the Preferred Stock as required by the NASD
Conduct Rules.  

We have participated in the preparation of the Registration Statement and the
Prospectus (as such terms are defined in the Underwriting Agreement) and have
exercised the usual standards of "due diligence" with respect thereto.  
Assuming that the Offering is commenced on [________], 1998, we recommend that
the offering price of the Preferred Stock be no higher than $[_______], which
price should in no event be considered or relied upon as an indication of the
actual value of the Preferred Stock.

Our recommendations are based on economic, market, financial and other
conditions as they exist at the date hereof and on other conditions and
circumstances relating to the Company as described in the Registration
Statement.  Changes in the conditions and circumstances relating to the Company
from those described in the Registration Statement and events occurring after
the date hereof, including changes in the markets in which the Company operates,
could materially affect the conclusions stated in this letter.  We shall not be

to comment on any events occurring after the date hereof or on any change to the
conditions or circumstances relating to the Company from those so described.

                              SL GREEN REALTY CORP.

                             ARTICLES SUPPLEMENTARY

                     ESTABLISHING AND FIXING THE RIGHTS AND
              PREFERENCES OF A SERIES OF SHARES OF PREFERRED STOCK


     SL Green Realty Corp., a Maryland corporation (the "Corporation"),
certifies to the State Department of Assessments and Taxation of Maryland that:

     FIRST: Under a power contained in Article VI of the Company's Articles of
Incorporation, as heretofore amended (which, as hereafter restated or amended
from time to time, are together with these Articles Supplementary herein called
the "Charter") the Board of Directors (the "Board"), by resolutions duly adopted
on May __, 1998, classified and designated 4,600,000 shares of the Preferred
Stock of the Corporation as ___% Series A Convertible, Cumulative Preferred
Stock, with the preferences, conversion and other rights, voting powers,
restrictions, limitations as to distributions, qualifications and terms and
conditions of redemption of the shares of such series of Preferred Stock, which
upon any restatement of the Charter shall be included as part of Article VI of
the Charter, as follows:

(1)  Designation and Number. A series of Preferred Stock of the Corporation,
designated the "___% Series A Convertible, Cumulative Preferred Stock" (the
"Series A Preferred"), is hereby established. The par value of the Series A
Preferred Stock is $.01 per share, which is not a change in the par value of the
Preferred Stock as set forth in the Charter. The number of shares of Series A
Preferred Stock shall be 4,600,000.

(2) Rank. The Series A Preferred shall, with respect to distribution rights and
rights upon voluntary or involuntary liquidation, dissolution or winding up of
the Corporation, rank (a) senior to all classes or series of Common Stock of the
Corporation ("Common Stock") and to all equity securities issued by the
Corporation the terms of which provide that such equity securities shall rank
junior to such Series A Preferred; (b) on a parity with all equity securities
issued by the Corporation other than those referred to in clauses (a) and (c);
and (c) junior to all equity securities issued by the Corporation which rank
senior to the Series A Preferred in accordance with Section 6(d). The term
"equity securities" shall not include convertible debt securities.

(3) Distributions.

     (a) Holders of shares of Series A Preferred shall be entitled to receive,
when and as authorized by the Board, out of funds legally available for the
payment of distributions, cumulative quarterly preferential cash distributions
equal to the greater of (i) ___% of the $25.00 liquidation preference per share
per annum (equivalent to a fixed annual amount of $___ per share) payable in
equal amounts of $_______ per share of Series A Preferred quarterly or (ii) the
cash dividends paid or payable (determined on each of the Distribution Payment
Dates referred to below) on a number of shares of Common Stock equal to the
number of shares of Common Stock (or portion thereof) into which, a share of
Series A Preferred is convertible. Distributions shall be cumulative from the
date of original issue and shall be payable quarterly in equal 

<PAGE>

amounts in arrears on the fifteenth day of each January, April, July and October
or, if not a business day, the next succeeding business day, beginning July 15,
1998 (each, a "Distribution Payment Date"). Any distribution (including the
initial distribution) payable on the Series A Preferred for any partial
distribution period shall be prorated and computed on the basis of a 360-day
year consisting of twelve 30-day months. Distributions shall be payable to
holders of record as they appear in the stock transfer records of the
Corporation at the close of business on the applicable record date, which shall
be the first day of the calendar month in which the applicable Distribution
Payment Date falls or such other date designated by the Board for the payment of
distributions that is not more than 30 nor less than 10 days prior to such
Distribution Payment Date (each, a "Distribution Record Date").

     (b) No distribution on the Series A Preferred shall be authorized by the
Board or paid or set apart for payment by the Corporation at such time as the
terms and provisions of any agreement of the Corporation, including any
agreement relating to its indebtedness, prohibits such authorization, payment or
setting apart for payment or provides that such authorization, payment or
setting apart for payment would constitute a breach thereof, or a default
thereunder, or if such authorization or payment shall be restricted or
prohibited by law. No interest, or sum of money in lieu of interest, shall be
payable in respect of any distribution payment or payments on the Series A
Preferred which may be in arrears.

     Notwithstanding the foregoing, distributions on the Series A Preferred
shall accumulate whether or not any of the foregoing restrictions exist, whether
or not there are funds legally available for the payment thereof and whether or
not such distributions are authorized. Accumulated but unpaid distributions on
the Series A Preferred shall not bear interest and holders of the Series A
Preferred shall not be entitled to any distributions in excess of full
cumulative distributions. Any distribution payment made on the Series A
Preferred shall first be credited against the earliest accumulated but unpaid
distribution due with respect to such shares which remains payable.

     (c) Except as provided in subsection 3(d) herein, unless full cumulative
distributions have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for such payment on the
Series A Preferred for all past distribution periods and the then current
distribution period, if any Series A Preferred are outstanding, no distributions
(other than in Common Stock or other equity securities of the Corporation
ranking junior to the Series A Preferred as to distributions and upon
liquidation, dissolution or winding up of the Corporation) shall be declared or
paid or set apart for payment nor shall any other distribution be declared or
made on any equity securities of the Corporation ranking, as to distributions or
upon liquidation, dissolution or winding up of the Corporation, on a parity with
or junior to the Series A Preferred for any period, nor shall any Common Stock,
or any other equity securities of the Corporation ranking junior to or on a
parity with the Series A Preferred as to distributions or upon liquidation,
dissolution or winding up of the Corporation, be redeemed, purchased or
otherwise acquired for any consideration (or any monies be paid to or made
available for a sinking fund for the redemption of any such equity securities)
by the Corporation (except (i) by conversion into or exchange for other equity
securities of the Corporation ranking junior to the Series A Preferred as to
distributions and upon liquidation, dissolution or winding up of the Corporation
or (ii) redemptions for the purpose of presently the Corporation's status as 

                                       2
<PAGE>

a real estate investment trust (a "REIT") under the Internal Revenue Code of
1986, as amended (the "Code").

     (d) When distributions are not paid in full (or a sum sufficient for such
full payment is not so set apart) upon the Series A Preferred and other equity
securities ranking on a parity as to distributions with the Series A Preferred,
all distributions declared upon the Series A Preferred and any other equity
securities ranking on a parity as to distributions with the Series A Preferred
shall be declared pro rata so that the amount of distributions declared per
share of Series A Preferred and such other equity securities shall in all cases
bear to each other the same ratio that accumulated distributions per share on
the Series A Preferred and such other equity securities (which shall not include
any accumulation in respect of unpaid distributions for prior distribution
periods if such equity securities do not have a cumulative distribution) bear to
each other. 

     (e) Holders of Series A Preferred shall not be entitled to any
distribution, whether payable in cash, property or shares, in excess of full
cumulative distributions on the Series A Preferred as described above.
Accumulated but unpaid distributions on the Series A Preferred will accumulate
as of the Distribution Payment Date on which they first become payable.

(4) Liquidation Preference.

     (a) In the event of any voluntary or involuntary liquidation, dissolution
or winding up of the Corporation, the holders of the Series A Preferred shall be
entitled to receive out of the assets of the Corporation legally available for
distribution to its stockholders remaining after payment or provisions for
payment of all debts and other liabilities of the Corporation liquidating
distributions, in cash or property at its fair market value as determined by the
Board, in the amount of a liquidation preference of $25.00 per share, plus an
amount equal to any accumulated and unpaid distributions to the date of payment,
before any distribution of assets is made to holders of Common Stock or any
other equity securities or the Corporation that rank junior to the Series A
Preferred as to distribution of assets upon the liquidation, dissolution or
winding up of the Corporation.

     (b) If upon any such voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, the available assets of the Corporation are
insufficient to make such full payment to holders of the Series A Preferred and
the corresponding amounts payable on all shares of other classes or series of
equity securities of the Corporation ranking on a parity with the Series A
Preferred as to distribution of assets upon the liquidation, dissolution or
winding up of the Corporation, then the holders of the Series A Preferred and
all other such classes or series of equity securities shall share ratably in any
such distribution of assets in proportion to the full liquidating distributions
to which they would otherwise be respectively entitled.


     (c) Written notice of any such liquidation, dissolution or winding up of
the Corporation, stating the payment date or dates when, and the place or places
where, the amounts distributable in such circumstances shall be payable, shall
be given by first class mail, postage pre-paid, not less than 30 or more than 60
days prior to the payment date stated therein, to each record holder of the
Series A Preferred at the respective addresses of such holders as the same shall
appear on the stock transfer records of the Corporation.

                                       3
<PAGE>

     (d) After payment of the full amount of the liquidating distributions to
which they are entitled, the holders of Series A Preferred shall have no right
or claim to any of the remaining assets of the Corporation. 

     (e) None of a consolidation or merger of the Corporation with or into
another entity, a merger of another entity with or into the Corporation, a
statutory stock exchange by the Corporation or a sale, lease or conveyance of
all or substantially all of the Corporation's property or business shall be
considered a liquidation, dissolution or winding up of the Corporation.

     (f) The liquidation preference of the outstanding shares of Series A
Preferred will not be added to the liabilities of the Corporation for the
purpose of determining whether under the Maryland General Corporation Law a
distribution may be made to stockholders of the Corporation whose preferential
rights upon dissolution of the Corporation are junior to those of holders of
Series A Preferred.

(5) Redemption.

     (a) Cash Redemption Right. Shares of Series A Preferred are not redeemable
prior to July 15, 2003. To ensure that the Corporation remains a qualified REIT
for federal income tax purposes, however, the Series A Preferred shall be
subject to the provisions of Article, VII of the Charter pursuant to which
Series A Preferred owned by a shareholder in excess of the Ownership Limit (as
defined in Article VII of the Charter, and as modified by subparagraph 9 hereof)
shall automatically be transferred to a Charitable Trust (as defined in Article
VII of the Charter) and the Corporation shall have the right to purchase such
shares, as provided in Article VII of the Charter. On and after July 15, 2003,
the Corporation, at its option, upon giving notice as provided below, may redeem
the Series A Preferred, in whole or from time to time in part, at the following
redemption prices per share of Series A Preferred if redeemed during the
twelve-month period beginning July 15 of the applicable year indicated below,
plus, in each case, all distributions accumulated and unpaid on such Series A
Preferred to the date of such redemption (the "Cash Redemption Right"):

     (b) Stock Redemption Right. In addition to the Cash Redemption Right set
forth in (a) above, on and after July 15, 2003, shares of Series A Preferred
shall be redeemable by the

                                       4
<PAGE>

Corporation, in whole or in part, at the option of the Corporation, for such
number of shares of Common Stock as equals the liquidation preference of the
Series A Preferred to be redeemed divided by the Conversion Price (defined in
subsection 7(a) herein) as of the opening of business on the date set for such
redemption (equivalent initially to a conversion rate of ______ shares of Common
Stock per Series A Preferred (the "Stock Redemption Right")). The Corporation
may exercise the Stock Redemption Right only if for 20 Trading Days (as defined
in Section 9 herein) within any period of 30 consecutive Trading Days, including
the last day of such period, the closing price of the Common Stock on the New
York Stock Exchange exceeds $___ per share, subject to adjustment, under the
circumstances described in Section 7 herein, with respect to the Conversion
Price. To exercise the Stock Redemption Right, the Corporation shall issue a
press release announcing the redemption prior to the opening of business on the
second trading day after the conditions described in the preceding sentences
have, from time to time, been met (the "Press Release"), but shall not issue a
Press Release prior to May 15, 2002. The Press Release shall announce the
redemption and set forth the number of shares of Series A Preferred that the
Corporation intends to redeem. The redemption date (which may not be before July
15, 2003) shall be selected by the Corporation, shall be specified in the notice
of redemption and shall be not less than 30 days or more than 60 days after the
date on which the Corporation issues the Press Release. Any date fixed for
redemption pursuant to this Section 5 is referred to herein as a "Redemption
Date."

(c) Limitations on Redemption.

     (i) The Corporation may exercise the Cash Redemption Right provided that
the redemption price (other than the portion thereof consisting of accumulated
and unpaid distributions) is payable solely out of the sale proceeds of other
equity securities of the Corporation, and from no other source. For purposes of
the preceding sentence, "equity securities" means any equity securities
(including Common Stock and Preferred Stock (as defined in the Charter)),
shares, interest, participation or other ownership interests (however
designated) and any rights (other than debt securities convertible into or
exchangeable for equity securities) or options to purchase any of the foregoing.

     (ii) If fewer than all of the outstanding shares of Series A Preferred are
to be redeemed or exchanged pursuant to the Cash Redemption Right or the Share
Redemption Right, the shares to be redeemed shall be determined pro rata or by
lot or in such other manner as prescribed by the Board. If such redemption is to
be by lot and, as a result of such redemption, any holder of shares of Series A
Preferred own, or be deemed by virtue of the attribution provisions of the Code
to own, in excess of 20% of the issued and outstanding shares of Series A
Preferred or 9.0% in value of all outstanding equity securities of the
Corporation, as the case may be, because such holder's shares of Series A
Preferred were not redeemed, or were only redeemed in part, then, except as
otherwise provided in the Charter, the Corporation will redeem the requisite
number of shares of Series A Preferred of such holder such that he will not hold
in excess of the Ownership Limit subsequent to such redemption. 

     (iii) Notwithstanding anything to the contrary contained herein, unless
full cumulative distributions on all shares of Series A Preferred shall have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for all past distribution periods
and the current distribution period, 

                                       5
<PAGE>

no shares of Series A Preferred shall be redeemed unless all outstanding shares
of Series A Preferred are simultaneously redeemed or exchanged; provided,
however, that the foregoing shall not prevent the purchase or acquisition of
shares of Series A Preferred pursuant to a purchase or exchange offer made on
the same terms to holders of all outstanding shares of Series A Preferred. In
addition, unless full cumulative distributions on all outstanding shares of
Series A Preferred have been or contemporaneously are declared and paid or
declared a and a sum sufficient for the payment thereof set apart for payment
for all past distributions periods and the then current distribution period, the
Corporation shall not purchase or otherwise acquire directly or indirectly any
shares of Series A Preferred or any equity securities of the Corporation ranking
junior to or on a parity with the Series A Preferred as to distributions or upon
liquidation, dissolution or winding up of the Corporation (except by conversion
into or exchange for equity securities of the Corporation ranking junior to the
Series A Preferred as to distributions and upon liquidation, dissolution or
winding up of the Corporation). 

     (iv) The foregoing provisions of subsections 5(c)(i)-(iii) shall not
prevent the purchase by the Corporation of Series A Preferred pursuant to
Article VII of the Charter or otherwise in order to ensure that the Trust
remains qualified as a REIT for federal income tax purposes.

     (v) Immediately prior to any redemption of shares of Series A Preferred,
the Corporation shall pay, in cash, any accumulated and unpaid distributions
through the Redemption Date, unless such Redemption Date falls after a
Distribution Record Date and prior to the corresponding Distribution Payment
Date, in which case each holder of Series A Preferred at the close of business
on such Distribution Record Date shall be entitled to the distribution payable
on such shares on the corresponding Distribution Payment Date notwithstanding
the redemption of such shares on or prior to such Distribution Payment Date.
Except as provided above, the Corporation will make no payment or allowance for
unpaid distributions, whether or not in arrears, on Series A Preferred for which
a notice of redemption has been given.

     (d) Mandatory Redemption. The Corporation shall redeem for cash all
outstanding shares of Series A Preferred on April 15, 2008 at a price of $25.00
per Series A Preferred, plus accumulated and unpaid distributions to the
redemption date.

     (e) Procedures for Redemption.

     (i) Notice of redemption pursuant to the Cash Redemption Right shall be (a)
given by publication in a newspaper of general circulation in the City of New
York, such publication to be made once a week for two successive weeks
commencing not less than 30 nor more than 60 days prior to the Redemption Date;
and (b) mailed, not less than 30 nor more than 60 days prior to the Redemption
Date, to each holder of record of shares of Series A Preferred to be redeemed,
notifying such holder of the Corporation's election to redeem such shares.
Notice of redemption pursuant to the Share Redemption Right shall be given not
more than four business days after the date on which the Corporation issues the
Press Release to each holder of record of the shares of Series A Preferred to be
redeemed. Such notice shall be provided by mail at such holder's address as the
same appears on the stock transfer records of the Corporation, or by publication
in a newspaper of general circulation in the City of New York. If the
Corporation elects to provide such notice by publication, it shall also promptly
mail notice of such 

                                       6
<PAGE>

redemption to the holders of the shares of Series A Preferred to be redeemed. No
failure to give such notice or any defect thereto or in the mailing thereof
shall affect the validity of the proceedings for the redemption of any shares of
Series A Preferred except as to the holder to whom notice was defective or not
given.

     (ii) In addition to any information required by law or by the applicable
rules of any exchange upon which the Series A Preferred may be listed or
admitted to trading, such notice shall state: (i) the Redemption Date, (ii) with
respect to the Cash Redemption Right, the case redemption price per share of
Series A Preferred and, with respect to the Share Redemption Right, the number
of shares of Common Stock to be issued with respect to each share of Series A
Preferred, (iii) the number of shares to be redeemed (and, if fewer than all the
shares of Series A Preferred are to be redeemed from such holder, the number of
shares to be redeemed from such holder), (iv) the place or places where
certificates for such shares of Series A Preferred are to be surrendered for
payment of the redemption price in cash, with respect to the Cash Redemption
Right, and in certificates representing Common Stock with respect to the Share
Redemption Right, (v) that distributions on the shares to be redeemed will cease
to accumulate on such Redemption Date and (vi) the date upon which the holder's
conversion rights, if any, as to such shares shall terminate. 

     (iii) On or after the Redemption Date, each holder of shares of Series A
Preferred to be redeemed shall present and surrender the certificates
representing his shares of Series A Preferred to the Corporation at the place
designated in the notice of redemption and thereupon the redemption price (in
cash or Common Stock, as applicable) of such shares shall be paid to or on the
order of the person whose name appears on such certificate representing shares
of Series A Preferred as the owner thereof and each surrendered certificate
shall be canceled. If fewer than all the shares represented by any such
certificate representing shares of Series A Preferred are to be redeemed, a new
certificate shall be issued representing the unredeemed shares.

     (iv) From and after the Redemption Date (unless the Corporation defaults in
payment of the redemption price), all distributions on the shares of Series A
Preferred designated for redemption in such notice shall cease to accumulate and
all rights of the holders thereof, except the right to receive the redemption
price thereof (including all accumulated and unpaid distributions up to the
Redemption Date), shall cease and terminate and such shares shall not thereafter
be transferred (except with the consent of the Corporation) on the Corporation's
books, and such shares shall not be deemed to be outstanding for any purpose
whatsoever. At its election, the Corporation, prior to a Redemption Date, may
irrevocably deposit the redemption price (including accumulated and unpaid
distributions) of the Series A Preferred so called for redemption in trust for
the holders thereof with a bank or trust company, in which case the redemption
notice to holders of the shares of Series A Preferred to be redeemed shall (i)
state the date of such deposit, (ii) specify the office of such bank or trust
company as the place of payment of the redemption price and (iii) require such
holders to surrender the certificates representing such shares at such place on
or about the date fixed in such redemption notice (which may not be later than
the Redemption Date) against payment of the redemption price (including all
accumulated and unpaid distributions to the Redemption Date). At the close of
business on a Redemption Date relating to the Share Redemption Right, each
holder of shares of Series A Preferred to be so redeemed (unless the Corporation
defaults in the delivery of the shares of

                                       7
<PAGE>

Common Stock payable on such Redemption Date) shall be deemed to be the record
holder of the number of shares of Common Stock into which such shares of Series
A Preferred are to be so redeemed, regardless of whether such holder has
surrendered the certificates representing the shares of Series A Preferred. Any
monies or Common Stock so deposited which remain unclaimed by the holders of
Series A Preferred at the end of two years after the Redemption Date shall be
returned by such bank or trust company to the Corporation.

     (f) Status of Redeemed Shares. Any shares of Series A Preferred that shall
at any time have been redeemed shall, after such redemption, have the status of
authorized by unissued Preferred Stock, without designation as to series until,
such shares are once more designated as part of a particular series by the
Board.

     (g) No Fractional Shares. No fractional shares or scrip representing
fractions of shares of Common Stock shall be issued upon redemption of a share
of Series A Preferred pursuant to the Corporation's Share Redemption Right.
Instead of any fractional interest in a share of Common Stock that would
otherwise be deliverable upon the redemption of a share of Series A Preferred,
the Corporation shall pay to the holder of such Series A Preferred an amount in
cash in respect of such fractional interest (computed to the nearest cent) based
upon the Current Market Price of Common Stock on the Trading Day immediately
preceding the Redemption Date. If more than one share of Series A Preferred
shall be surrendered for redemption at one time by the same holder, the number
of full shares of Common Stock issuable upon redemption thereof shall be
computed on the basis of the aggregate number of shares of Series A Preferred so
surrendered. 

     (h) Shares of Common Stock Issuable Upon Redemption. The Corporation
covenants that any shares of Common Stock issued upon redemption of the Series A
Preferred shall be validly issued, fully paid and non-assessable.

(6) Voting Rights.

     (a) Holders of the Series A Preferred shall not have any voting rights,
except as provided by law and as described below.

     (b) Whenever distributions on any shares of Series A Preferred shall be in
arrears for six or more quarterly periods (a "Preferred Distribution Default"),
the holders of such shares of Series A Preferred (voting separately as a class
with all other equity securities ranking on a parity with the Series A Preferred
as to distributions and upon voluntary or involuntary liquidation, dissolution
or winding up of the Corporation upon which like voting rights have been
conferred and are exercisable ("Parity Preferred Stock")) shall be entitled to
vote for the election of a total of two additional directors of the Corporation
(the "Preferred Stock Directors") who shall each be elected for one-year terms.
Such election shall be held at a special meeting called by the holders of record
of at least 20% of the outstanding shares of Series A Preferred or the holders
of shares of any other series of Parity Preferred Stock so in arrears (unless
such request is received less than 90 days before the date fixed for the next
annual or special meeting of shareholders) or, if the request for a special
meeting is received by the Corporation less than 90 days before the date fixed
for the next annual or special meeting of the shareholders, at the next annual
or special meeting of stockholders, and at each subsequent annual meeting until
all distributions

                                       8
<PAGE>


accumulated on such shares of Series A Preferred for the past distribution
periods and the distribution for the then current distribution period shall have
been fully paid or authorized and a sum sufficient for the payment thereof set
aside for payment in full. In such cases, the entire Board of Directors of the
Corporation shall be increased by two directors.

     (c) If and when all accumulated distributions and the distribution for the
current distribution period on the Series A Preferred shall have been paid in
full or set aside for payment in full, the holders of shares of Series A
Preferred shall be divested of the voting rights set forth in Section 6(b)
herein (subject to revesting in the event of each and every Preferred
Distribution Default) and, if all accumulated distributions and the distribution
for the current distribution period have been paid in full or set aside for
payment in full on all other series of Parity Preferred Stock upon which like
voting rights have been conferred and are exercisable, the term of office of
each Preferred Stock Director so elected shall terminate. So long as a Preferred
Distribution Default shall continue, any vacancy in the office of a Preferred
Stock Director may be filled by written consent of the Preferred Stock Director
remaining in office, or if there is no such remaining director, by vote of
holders of a majority of the outstanding shares of Series A Preferred and any
other such other series of Parity Preferred Stock voting as a single class. Any
Preferred Stock Director may be removed at any time with or without cause by the
vote of, and shall not be removed otherwise than by the vote of, the holders of
record of a majority of the outstanding shares of Series A Preferred when they
have the voting rights set forth in Section 6(b) (voting separately as a class
with all other series of Parity Preferred Stock upon which like voting rights
have been conferred and are exercisable). The Preferred Stock Directors shall
each be entitled to one vote per director on any matter presented to the Board.

     (d) So long as any shares of Series A Preferred remain outstanding, the
Corporation shall not, without the affirmative vote or consent of the holders of
at least two-thirds of the shares of Series A Preferred outstanding at the time,
given in person or by proxy, either in writing or at a meeting (such series
voting separately as a class), (i) authorize or create, or increase the
authorized or issued amount of, any equity securities ranking prior to Series A
Preferred with respect to the payment of distributions or the distribution of
assets upon voluntary or involuntary liquidation, dissolution or winding up of
the Corporation or reclassify any authorized stock of the Corporation into any
such equity securities, or create, authorize or issue any obligation or security
convertible or exchangeable into or evidencing the right to purchase any such
stock; or (ii) amend, alter or repeal the provisions of the Charter or these
Articles Supplementary, whether by merger or consolidation (an "Event") or
otherwise, so as to materially and adversely affect any right, preference,
privilege or voting power of the Series A Preferred or the holders thereof;
provided, however, with respect to the occurrence of any of the Events set forth
in (ii) above, so long as Series A Preferred remain outstanding with the terms
thereof materially unchanged, taking into account that, upon the occurrence of
an Event, the Corporation may not be the surviving entity and such surviving
entity may thereafter be the issuer of the Series A Preferred, the occurrence of
any such Event shall not be deemed to materially adversely affect such rights,
preferences, privileges or voting powers of holders of Series A Preferred; and
provided further that (x) any increase in the amount of the authorized shares of
Preferred Stock or the creation or issuance of any other series of Preferred
Stock, or (y) any increase in the amount of authorized shares of Series A
Preferred or any other series of Preferred Stock, in each case ranking on a
parity with or junior to the Series A Preferred with respect to payment of
distributions and the distribution of assets upon voluntary or involuntary

                                       9
<PAGE>

liquidation, dissolution or winding up of the Corporation, shall not be deemed
to materially and adversely affect such rights, preferences, privileges or
voting powers.

     (e) The foregoing voting provisions shall not apply if, at or prior to the
time when the act with respect to which such vote would otherwise be required
shall be effected, all outstanding shares of Series A Preferred shall have been
converted, redeemed or called for redemption upon proper notice and sufficient
funds or shares of Common Stock, as applicable, shall have been deposited in
trust to effect such redemption.

(7) Conversion.

     (a) Subject to the restrictions on transfer and ownership referenced in
Article VII of the Charter, any number of whole (but not fractional) shares of
Series A Preferred shall be convertible at any time, at the option of the
holders thereof, into fully paid and non-assessable shares of Common Stock at a
conversion price of $____ per share of Common Stock (equivalent to a conversion
rate of ___ shares of Common Stock for each share of Series A Preferred),
subject to adjustment as described in Section 7(f) herein (the "Conversion
Price"), provided, however, that the right to convert shares of Series A
Preferred called for redemption pursuant to Section 5 shall terminate at the
close of business on the Redemption Date, unless the Corporation shall default
in making payment of the redemption price.

     (b) To exercise the conversion right, the holder of shares of Series A
Preferred to be converted shall surrender the certificate representing such
shares, duly endorsed or assigned to the Corporation or in blank, at the
principal office of the Transfer Agent accompanied by written notice to the
Corporation that the holder thereof elects to convert such shares of Series A
Preferred. Unless the shares issuable on conversion are to be issued in the same
name as the name in which such shares of Series A Preferred are registered, in
which case the Corporation shall bear the related taxes, each share surrendered
for conversion shall be accompanied by instruments of transfer, in form
satisfactory to the Corporation, duly executed by the holder or such holder's
duly authorized attorney and an amount sufficient to pay any transfer or similar
tax (or evidence reasonably satisfactory to the Corporation demonstrating that
such taxes have been paid). 

     (c) Each conversion shall be deemed to have been effected immediately prior
to the close of business on the date on which the certificates for shares of
Series A Preferred shall have been surrendered and such notice (and if
applicable, payment of an amount equal to the distribution payable on such
shares) received by the Corporation as aforesaid, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby at such time on such
date, and such conversion shall be at the Conversion Price in effect at such
time and on such date unless the stock transfer books of the Corporation shall
be closed on that date, in which event such person or persons shall be deemed to
have become such holder or holders of record at the close of business on the
next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date on which such
shares have been surrendered and such notice received by the Corporation.

                                       10

<PAGE>

    (d)   Holders of shares of Series A Preferred at the close of business on a
Distribution Record Date shall be entitled to receive the distribution payable
on such shares on the corresponding Distribution Payment Date notwithstanding
the conversion of such shares following such Distribution Record Date and prior
to such Distribution Payment Date. However, certificates representing shares of
Series A Preferred surrendered for conversion during the period between the
close of business on any Distribution Record Date and ending with the opening of
business on the corresponding Distribution Payment Date (except shares converted
after the issuance of a notice of redemption with respect to a Redemption Date
during such period or coinciding with such Distribution Payment Date) shall be
accompanied by payment of an amount equal to the distribution payable on such
shares on such Distribution Payment Date. A holder of shares of Series A
Preferred on a Distribution Record Date who (or whose transferee) tenders any
such shares for conversion into shares of Common Stock on such Distribution
Payment Date shall receive the distribution payable by the Corporation on such
shares of Series A Preferred Stock on such date, and the converting holder need
not include payment of the amount of such distribution upon surrender of
certificates representing such shares of Series A Preferred for conversion.
Except as provided above, the Corporation shall make no payment or allowance for
unpaid distributions, whether or not in arrears, on converted shares or for
distribution on the shares of Common Stock that are issued upon such conversion.

          As promptly as practicable after the surrender of certificates for 
shares of Series A Preferred as aforesaid, the Corporation shall issue and shall
deliver at such office to such holder, or on his written order, a certificate or
certificates for the number of full shares of Common Stock issuable upon the
conversion of such shares in accordance with the provisions of this Section 7,
and any fractional interest in respect of a share of Common Stock arising upon
such conversion shall be settled as provided in subsection (e) of this Section
7.

    (e)   No fractional share of scrip representing fractions of shares of 
Common Stock shall be issued upon conversion of the Series A Preferred. Instead
of any fractional interest in a share of Common Stock that would otherwise be
deliverable upon the conversion of a share of Series A Preferred, the
Corporation shall pay to the holder of such share an amount in cash in respect
of such fractional interest based upon the Current Market Price of a share of
Common Stock on the Trading Day immediately preceding the date of conversion. If
more than one share of Series A Preferred, shall be surrendered for conversion
at one time by the same holder, the number of full shares of Common Stock
issuable upon conversion thereof shall be computed on the basis of the aggregate
number of shares of Series A Preferred so surrendered.

(f)   Conversion Price Adjustments.

      The Conversion Price shall be adjusted from time to time as follows:

      (i)   If the Corporation shall after the date on which shares of Series A
Preferred are first issued (the "Issue Date") (A) pay or make a distribution to
holders of its equity securities in shares of Common Stock, (B) subdivide its
outstanding shares of Common Stock into a greater number of shares, (C) combine
its outstanding shares of Common Stock into a small number of shares or (D)
issue any shares of stock by reclassification of its Common Stock, the
Conversion Price in effect at the opening of 

                                       11
<PAGE>

business on the day following the date fixed for the determination of
shareholders entitled to receive such distribution or at the opening of business
on the day following the day on which such subdivision, combination or
reclassification becomes effective, as the case may be, shall be adjusted so
that the holder of any Series A Preferred thereafter surrendered for conversion
shall be entitled to receive the number of shares of Common Stock that such
holder would have owned or have been entitled to receive after the happening of
any of the events described above had such shares of Series A Preferred been
converted immediately prior to the record date in the case of a subdivision,
combination or reclassification. An adjustment made pursuant to this subsection
(i) shall become effective immediately after the opening of business on the day
next following the record date (except as provided in subsection (j) below) in
the case of a distribution and shall become effective immediately after the
opening of business on the day next following the effective date in the case of
a subdivision, combination or reclassification.

      (ii) If the Corporation shall issue after the Issue Date rights, options 
or warrants to all holders of Common Stock entitling them to subscribe for or
purchase shares of Common Stock (or securities convertible into or exchangeable
for Common Stock) at a price per share less than the Fair Market Value per share
of Common Stock on the record date for the determination of shareholders
entitled to receive such rights, options or warrants, then the Conversion Price
in effect at the opening of business on the day next following such record date
shall be adjusted to equal the price determined by multiplying (I) the
Conversion Price in effect immediately prior to the opening of business on the
day following the date fixed for such determination by (II) a fraction, the
numerator of which shall be the sum of (A) the number of shares of Common Stock
outstanding on the close of business on the date fixed for such determination
and (B) the number of shares that the aggregate proceeds to the Corporation from
the exercise of such rights, options or warrants for shares of Common Stock
would purchase at such Fair Market Value, and the denominator of which shall be
the sum of (A) the number of shares Common Stock outstanding on the close of
business on the date fixed for such determination and (B) the number of
additional shares of Common Stock offered for subscription or purchase pursuant
to such rights, options or warrants. Such adjustment shall become effective
immediately after the opening of business on the day next following such record
date (except as provided in subsection (j) below). In determining whether any
rights, options or warrants entitle the holders of Common Stock to subscribe for
or purchase Common Stock at less than the Fair Market Value, there shall be
taken into account any consideration received by such holders upon issuance and
upon exercise of such rights, options or warrants, the value of such
consideration, if other than cash, to be determined by the Corporation's Chief
Executive Officer or the Board. 


      (iii) If the Corporation shall distribute to all holders of its Common 
Stock any equity securities of the Corporation (other than Common Stock) or
evidence of its indebtedness or assets (excluding cash distributions paid out of
the total equity applicable to Common Stock distributions paid out of the total
equity applicable to Common Stock, including revaluation equity, less the amount
of stated capital attributable to shares of Common Stock, determined on the
basis of the most recent annual consolidated cost basis and current value basis
and quarterly consolidated balance sheets of the Corporation and its
consolidated subsidiaries available at the time of the declaration of the
distribution) or rights, options or warrants to subscribe for or purchase any of
its securities (excluding those rights, options and warrants issued to all
holders of Common Stock entitling them to subscribe for or purchase Common
Stock, which rights, options and warrants are referred to in and treated under
subsection (ii) above) (any of the foregoing being hereinafter in this
subsection (iii) called the "Securities"), then in each case the 

                                       12
<PAGE>


Conversion Price shall be adjusted so that it shall equal the price determined
by multiplying (I) the Conversion Price in effect immediately prior to the close
of business on the date fixed for the determination of shareholders entitled to
receive such distribution by (II) a fraction, the numerator of which shall be
the Fair Market Value per share of Common Stock on the record date mentioned
below less the then fair market value (as determined by the Corporation's Chief
Executive Officer or the Board, whose determination shall be conclusive) of the
portion of the equity securities or assets or evidences of indebtedness so
distributed or of such rights, options or warrants applicable to one share of
Common Stock, and the denominator of which shall be the Fair Market Value per
share of Common Stock on the record date mentioned below. Such adjustment shall
become effective immediately at the opening of business on the business day next
following (except a provided in subsection (j) below) the record date for the
determination of shareholders entitled to receive such distribution. For the
purposes of this subsection (iii), the distribution of a Security, which is
distributed not only to the holders of Common Stock on the date fixed for the
determination of shareholders entitled to such distribution of such Security,
but also is distributed with each share of Common Stock delivered to a person
converting a share of Series A Preferred after such determination date, shall
not require an adjustment of the conversion Price pursuant to this subsection
(iii); provided that on the date, if any, on which a person converting a share
of Series A Preferred would no longer be entitled to receive such Security with
a share of Common Stock (other than as a result of the termination of all such
Securities), a distribution of such Securities shall be deemed to have occurred
and the Conversion Price shall be adjusted as provided in this subsection (iii)
(and such day shall be deemed to be "the date fixed for the determination of the
shareholders entitled to receive such distribution" and "the record date" within
the meaning of the two preceding sentences). 


       (iv) If (I) the Corporation shall make cash distributions to all holders 
of its Common Stock (excluding any cash portion of distributions referred to in
subsection (iii) above) which, when combined with (A) all such all-cash
distributions made within the preceding 12 months in respect of which no
adjustment has been made, plus months in respect of which no adjustment has been
made, plus months in respect of which no adjustment has been made, plus (B) the
amount by which any cash and the fair market value, as of the relevant
expiration date, of other consideration payable in respect of any tender offers
by the Corporation for Common Stock expired within the preceding 12 months in
respect of which no adjustment has been made exceeds the Current Market Price of
the Common Stock acquired in such tender offers, exceeds 15% of the Company's
market capitalization (being the product of the then Current Market Price of the
Common Stock times the number of shares of Common Stock then outstanding) on the
record date for such distribution (the amount by which such cash distributions,
when combined with (A) plus (B) above exceeds such 15% of such market
capitalization being referred to herein as the "Excess Cash Amount"), or (II) a
tender offer made by the Corporation or any subsidiary for all or any portion of
the shares of Common Stock shall expire and such tender offer shall require
payment to shareholders of aggregate consideration having a fair market value
which, when combined with (C) the aggregate of the amount by which the cash plus
the fair market value, as of the expiration of such tender offer, of other
consideration payable in respect of any other tender offer by the Corporation or
any subsidiary for all or any portion of the shares of Common Stock expiring
within 12 months preceding the expiration of such tender offer and in respect of
which no adjustment pursuant to this subsection (f)(iv) has been made exceeds
the Current Market Price of the Common Stock acquired in such tender offer, plus
(D) the aggregate amount of any distributions to all holders of Common Stock
made exclusively in cash within the 


                                       13
<PAGE>

12 months preceding the expiration of such tender offer and in respect of which
no adjustment pursuant to clause (I) above has been made, exceeds 15% of the
product of the Current Market Price per share of the Common Stock as of the last
time tenders could have been made pursuant to such tender offer times the number
of shares of Common Stock outstanding (including tendered shares) (the amount by
which such aggregate consideration, when combined with (C) plus (D) above,
exceeds such 15% of such product being referred to herein as the "Excess Tender
Amount"), then in each case the Conversion Price shall be adjusted so that it
shall equal the price determined by multiplying (Y) the Conversion Price in
effect immediately prior to the close of business on the date fixed for the
determination of shareholders entitled to receive such distribution by (Z) a
fraction, the numerator of which shall be the Fair Market Value per share of
Common Stock on the record date mentioned below less the Excess Cash Amount, if
any, and the Excess Tender Amount, if any, and the denominator of which shall be
the Fair Market Value per share of Common Stock on the record date mentioned
below. Such adjustment shall become effective immediately at the opening of
business on the business day next following (except as provided in subsection
(j) below) the record date for the determination of shareholders entitled to
receive such distribution, or the expiration date of such tender offer, as the
case may be. 

         (v) No adjustment in the Conversion Price shall be required unless such
adjustment would require a cumulative increase or decrease of at least 1% in
such price; provided, however, that any adjustments that by reason of this
subsection (v) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment until made; and provided, further,
that any adjustment shall be required and made in accordance with the provisions
of this Section 7(other than this subsection (v)) not later than such time as
may be required in order to preserve the tax-free nature of a distribution to
the holders of Common Stock. Notwithstanding any other provisions of this
Section 7, the Corporation shall not be required to make any adjustment of the
Conversion Price for the issuance of any shares of Common Stock pursuant to any
plan providing for the reinvestment of distributions or interest payable on
securities of the Corporation and the investment of additional optional amounts
in shares of Common Stock under such plan. All calculations under this Section 7
shall be made to the nearest cent with ($.005 being rounded upward) or to the
nearest one-tenth of a share (with .05 of a share being rounded upward), as the
case may be. Anything in this subsection (f) to the contrary notwithstanding,
the Corporation shall be entitled, to the extent permitted by law, to make such
reductions in the Conversion Price, in addition to those required by this
subsection (f), as it in its discretion shall determine to be advisable in order
that any share distributions, subdivision of shares, reclassification or
combination of shares, distribution of rights, options or warrants to purchase
shares or securities, or a distribution of other assets (other than cash
distributions) hereafter made by the Corporation to its shareholders shall not
be taxable.


      (g) If the Corporation shall be a party to any transaction (including,
without limitation, a merger, consolidation, statutory share exchange, self
tender offer for all or substantially all of the shares of Common Stock, sale of
all or substantially all of the Corporation's assets or recapitalization of the
Common Stock and excluding any transaction as to which subsection (f)(i) of this
Section 7 shall apply) (each of the foregoing being referred to herein as a
"Transaction"), in each case as a result of which shares of Common Stock shall
be converted into the right to receive shares, stock, securities or other
property (including cash or any combination thereof), each share of Series A
Preferred, if convertible after the consummation of the Transaction, which is
not converted into the right to receive shares, stock, 

                                       14
<PAGE>

securities or other property in connection with such Transaction shall
thereafter be convertible into the kind and amount of shares, stock, securities
and other property (including cash or any combination thereof) receivable upon
the consummation of such Transaction by a holder of that number of shares of
Common Stock into which one share of Series A Preferred was convertible
immediately prior to such Transaction, assuming such holder of Common Stock (i)
is not a Person with which the Corporation consolidated or into which the
Corporation merged into the Corporation or to which such sale or transfer was
made as the case may be (a "Constituent Person"), or an affiliate of a
Constituent Person and (ii) failed to exercise his rights of the election, if
any, as to the kind or amount of shares, stock, securities and other property
(including cash or any combination thereof) receivable upon consummation of such
Transaction (each a "Non-Electing Share") (provided that if the kind and amount
of shares stock, securities and other property (including cash or any
combination thereof) receivable upon consummation of such Transaction is not the
same for each Non-Electing Share, the kind and amount receivable by each
Non-Electing Share shall be deemed to be the kind and amount receivable per
share by a plurality of the Non-Electing Shares). The Corporation shall not be a
party to any Transaction unless the terms of such Transaction are consistent
with the provisions of this subsection (g), and it shall not consent or agree to
the occurrence of any Transaction until the Corporation has entered into an
agreement with the successor or purchasing entity, as the case may be, for the
benefit of the holders of the Series A Preferred that will contain provisions
enabling the holders of the share of Series A Preferred that remain outstanding
after such Transaction to convert into the consideration received by holders of
Common Stock at the Conversion Price in effect immediately prior to such
Transaction. The provisions of this subsection (g) shall similarly apply to
successive Transactions.

    (h)  If:

         (i) the Corporation shall declare a distribution on the Common Stock
(other than in cash out of the total equity applicable to shares of Common
Stock, including revaluation equity, less the amount of stated capital
attributable to shares of Common Stock, determined on the basis of the most
recent annual consolidated cost basis and current value basis and quarterly
consolidated balance sheets of the Corporation and its consolidated subsidiaries
available at the time of the declaration of the distribution) or there shall be
a reclassification, subdivision or combination of Common Stock; or

         (ii) the Corporation shall authorize the granting to the holders of the
Common Stock of rights, options or warrants to subscribe for or purchase any
shares of any class or any other rights, options or warrants; or 

         (iii) the Corporation shall authorize the payment of any Excess Cash
Amount or Excess Tender Amount; or 


         (iv) there shall be any reclassifications of the Common Stock (other
than an event to which subsection (f)(i) of this Section 7 applied) or any
consolidation or merger to which the Corporation is a party and for which
approval of any shareholders of the Corporation is required, or a statutory
share exchange involving the conversion or exchange of Common Stock into
securities or other property, or a self tender offer by the Stock for all or
substantially all of its outstanding Common Stock, or the sale or transfer of
all or substantially all of the assets 

                                       15
<PAGE>

of the Corporation as an entity and for which approval of any stockholder of the
Corporation is required; or

       (v) there shall occur the voluntary or involuntary liquidation, 
dissolution or winding up of the Corporation, 

       then the Corporation shall cause to be filed with the Transfer Agent and
shall cause to mailed to the holders of the Series A Preferred at their
addresses as shown on the stock transfer records of the Corporation, as promptly
as possible, but at least 15 days prior to the applicable date hereinafter
specified, a notice stating (A) the date on which a record is to be taken for
the purpose of such distribution or rights, options or warrants, or, if a record
is not to be taken, the date as of which the holders of Common Stock of record
to be entitled to such distribution or rights, options or warrants are to be
determined or (B) the date on which such reclassification, subdivision,
combination, consolidation, merger, statutory share exchange, sale, transfer,
liquidation, dissolution or winding up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities or other
property, if any, deliverable upon such reclassification, subdivision,
combination, consolidation, merger, statutory share exchange, sale, transfer,
liquidation, dissolution or winding up. Failure to give or receive such notice
or any defect therein shall not affect the legality or validity of the
proceedings described in this Section 7.

        (i) Whenever the Conversion Price is adjusted as herein provided, the
Corporation shall promptly file with the Transfer Agent an officer's certificate
setting forth the Conversion Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment, which certificate shall
be conclusive evidence of the correctness of such adjustment absent manifest
error. Promptly after delivery of such certificate, the Corporation shall
prepare a notice of such adjustment of the Conversion Price setting forth the
adjusted Conversion Price and the effective date such adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Price
to the holder of each shares of Series A Preferred at such holder's last address
as shown on the stock transfer records of the Corporation.

        (j) In any case in which subsection (f) of this Section 7 provides that 
an adjustment shall become effective on the date next following the record date
for an event, the Corporation may defer until the occurrence of such event (A)
issuing to the holder of any shares of Series A Preferred converted after such
record date and before the occurrence of such event the additional shares of
Common Stock issuable upon such conversion by reason of the adjustment required
by such event over and above the shares of Common Stock issuable upon such
conversion before giving effect to such adjustment and (B) fractionalizing any
shares of Series A Preferred and/or paying to such holder any amount of cash in
lieu of any fraction pursuant to subsection (e) of this Section 7. 


        (k) There shall be no adjustment of the Conversion Price in case of the 
issuance of any equity securities of the Corporation in a reorganization,
acquisition or other similar transaction except as specifically set forth in
this Section 7. If any action or transaction would require adjustment of the
Conversion Price pursuant to more than one subsection of this Section 

                                       16
<PAGE>

7, only one adjustment shall be made, and such adjustment shall be the amount of
adjustment that has the highest absolute value.


        (l) If the Corporation shall take any action affecting the Common Stock,
other than action described in this Section 7, that in the opinion of the Board
would materially adversely affect the conversion rights of the holders of the
Series A Preferred, the Conversion Price for the Series A Preferred may be
adjusted, to the extent permitted by law, in such manner, if any, and at such
time, as the Board, in its sole discretion, may determine to be equitable in the
circumstances. 


        (m) The Corporation covenants that it will at all times reserve and keep
available, free from preemptive rights, out of the aggregate of its authorized
but unissued shares of Common Stock, for the purpose of effecting conversion of
the Series A Preferred, the full number of shares of Common Stock deliverable
upon the conversion of all outstanding shares of Series A Preferred not
theretofore converted. For purposes of this subsection (m), the number of shares
of Common Stock that shall be deliverable upon the conversion of all outstanding
shares of Series A Preferred shall be computed as if at the time of computation
all such outstanding shares were held by a single holder.

             The Corporation covenants that any shares of Common Stock issued
upon conversion of the Series A Preferred shall be validly issued, fully paid
and non-assessable. Before taking any action that would cause an adjustment
reducing the Conversion Price below the then-par value of the shares of Common
Stock deliverable upon conversion of the Series A Preferred, the Corporation
will take any action that, in the opinion of its counsel, may be necessary in
order that the Corporation may validly and legally issue fully paid and
non-assessable shares of Common Stock at such adjusted Conversion Price.

             Prior to the delivery of any securities that the Corporation
shall be obligated to deliver upon conversion of the Series A Preferred, the
Corporation shall endeavor to comply with all federal and state laws and
regulations thereunder requiring the registration of such securities with, or
any approval of or consent to the delivery thereof by any governmental
authority.

        (n) The Corporation will pay any and all documentary stamp or similar 
issue or transfer taxes payable in respect of the issue or delivery of Common
Stock or other securities or property on conversion or redemption of the Series
A Preferred pursuant hereto; provided, however, that the Trust shall not be
required to pay any tax that may be payable in respect of any transfer involved
in the issue or delivery of Common Stock or other securities or property in a
name other than that of the record holder of the Series A Preferred to be
converted or redeemed, and no such issue or delivery shall be made unless and
until the person requesting such issue or delivery has paid to the Corporation
the amount of any such tax or established, to the reasonable satisfaction of the
Corporation, that such tax has been paid.

(8) Ownership Limitations. Notwithstanding Article VII of the Articles, the
provisions of this Section 8 shall apply with respect to the limitations on the
ownership and acquisition of shares of Series A Preferred.

                                       17
<PAGE>

   (a) Restriction on Ownership and Transfer.

       (i) Except as provided in Section 8(h), no Person shall Acquire any 
shares of Series A Preferred if, as the result of such Acquisition, such Person
shall Beneficially Own or Constructively Own shares of Series A Preferred in
excess of the Ownership Limit;

       (ii) Except as provided in Section 8(h), no Person shall Beneficially Own
or Constructively Own any shares of Series A Preferred such that such Person
would Beneficially Own or Constructively Own Capital Stock in excess of the
Aggregate Stock Ownership Limit; 

        (iii) Except as provided in Section 8(h), any Acquisition (whether or
not such Acquisition is the result of a transaction entered into through the
facilities of the New York Stock Exchange, Inc. (the "NYSE")) that, if
effective, would result in any Person Beneficially Owning Series A Preferred in
excess of the Ownership Limit shall be void Series A ab initio as to the
Acquisition of such Series A Preferred which would be otherwise Beneficially
Owned by such Person in excess of the Ownership Limit; and the intended
transferee shall acquire no rights in such Series A Preferred;

        (iv) Except as provided in Section 8(h), any Acquisition (whether or 
not such Acquisition is the result of a transaction entered into through the
facilities of the NYSE) that, if effective, would result in any Person
Constructively Owning Series A Preferred in excess of the Ownership Limit shall
be void ab initio as to the Acquisition of such Series A Preferred which would
be otherwise Constructively Owned by such Person in excess of the Ownership
Limit; and the intended transferee shall acquire no rights in such Series A
Preferred; and

        (v) Notwithstanding any other provisions contained in this Section 8, 
any Transfer (whether or not such Transfer is the result of a transaction
entered into through the facilities of the NYSE) or other event that, if
effective, would result in the Corporation being "closely held" within the
meaning of Section 856(h) of the Code, or would otherwise result in the
Corporation failing to qualify as a REIT (including, but not limited to, a
Transfer other event that would result in the Corporation owning (directly or
Constructively) an interest in a tenant that is described in Section
856(d)(2)(B) of the Code if the income derived by the Corporation from such
tenant would cause the Corporation to fail to satisfy any of the gross income
requirements of Section 856(c) of the Code) shall be void ab initio as to the
Transfer of the Series A Preferred or other event which would cause the
Corporation to be "closely held" within the meaning of Section 856(h) of the
Code or would otherwise result in the Corporation failing to qualify as a REIT;
and the intended transferee or owner or Constructive or Beneficial Owner shall
acquire or retain no rights in such Series A Preferred. 


     (b) Conversion Into and Exchange For Series A Excess Preferred. If,
notwithstanding the other provisions contained in this Section 8, at any time
after the date of the Issue Date, there is a purported Transfer or Acquisition
(whether or not such Transfer or Acquisition is the result of a transaction
entered into through the facilities of the NYSE), change in the capital
structure of the Corporation or other event such that one or more of the
restrictions on ownership and transfers described in Section 8(a), above, has
been violated, then the Series A Preferred being Transferred or Acquired (or in
the case of an event other than a Transfer or Acquisition, the Series A
Preferred owned or Constructively Owned or Beneficially Owned or, if the 


                                       18
<PAGE>

next sentence applies, the Series A Preferred identified in the next sentence)
which would cause one or more of the restrictions on ownership or transfer to be
violated (rounded up to the nearest whole share) shall be automatically
converted into an equal number of shares of Series A Excess Preferred. If at any
time of such purported Transfer or Acquisition any of the shares of the Series A
Preferred are then owned by a depositary to permit the trading of beneficial
interests in fractional shares of Series A Preferred, then shares of Series A
Preferred that shall be converted to Series A Excess Preferred shall be first
taken from any Series A Preferred that is not in such depositary that is
Beneficially Owned or Constructively Owned by the Person whose Beneficial
Ownership or Constructive Ownership would otherwise violate the restrictions of
Section 8(a) prior to converting any shares in such depositary. Any conversion
pursuant to this subparagraph shall be effective as of the close of business on
the Business Day prior to the date of such Transfer or other event.

     (c) Remedies For Breach. If the Board of Directors or its designees shall
at any time determine in good faith that a Transfer or other event has taken
place in violation of Section 8(a) or that a Person intends to Transfer or
Acquire, has attempted to Transfer or Acquire or may Transfer or Acquire direct
ownership, beneficial ownership (determined without reference to any rules of
attribution), Beneficial Ownership or Constructive Ownership of any shares of
the Corporation in violation of Section 8(a), the Board of Directors or its
designees shall take such action as it deems advisable to refuse to give effect
to or to prevent such Transfer, Acquisition or other event, including, but not
limited to, causing the Corporation to purchase such shares upon the terms and
conditions specified by the Board of Directors in its sole discretion, refusing
to give effect to such Transfer, Acquisition or other event on the books of the
Corporation or instituting proceedings to enjoin such Transfer, Acquisition or
other event; provided, however, that any Transfer or Acquisition (or, in the
case of events other than a Transfer or Acquisition, ownership or Constructive
Ownership or Beneficial Ownership) in violation of Section 8(a) shall
automatically result in the conversion described in Section 8(b), irrespective
of any action (or non-action) by the Board of Directors. 

     (d) Notice of Restricted Transfer. Any Person who Acquires or attempts to
Acquire or Beneficially Owns or Constructively Owns shares of Series A Preferred
in excess of the aforementioned limitations, or any Person who is or attempts to
become a transferee such that Series A Excess Preferred results under the
provisions of these Articles, shall immediately give written notice or, in the
event of a proposed or attempted Transfer, give at least 15 days prior written
notice to the Corporation of such event and shall provide to the Corporation
such other information as it may request in order to determine the effect of any
such Transfer on the corporation's status as a REIT. 

     (e) Owners Required To Provide Information. From and after the Issue Date,
each Person who is a beneficial owner or Beneficial Owner or Constructive Owner
of Series A Preferred and each Person (including the stockholder of record) who
is holding Series A Preferred for a Beneficial Owner or Constructive Owner shall
provide to the Corporation such information that the Corporation may request, in
good faith, in order to determine the Corporation's status as a REIT. 

     (f) Remedies Not Limited. Nothing contained in this Section 8 (but subject
to Section 8(l)) shall limit the authority of the Board of Directors to take
such other action as it deems 


                                       19
<PAGE>

necessary or advisable to protect the Corporation and the interests of its
stockholders by preservation of the Corporation's status as a REIT. 

     (g) Ambiguity. In the case of an ambiguity in the application of any of the
provisions of this Section 8, including any definition contained in Section 9,
the Board of Directors shall have the power to determine the application of the
provisions of this Section 8 with respect to any situation based on the facts
known to it (subject, however, to the provisions of Section 8(l)). 

     (h) Exceptions.

         (i) Subject to Section 8(a)(iv), the Board of Directors, in its sole
and absolute discretion, with the advice of the Corporation's tax counsel, may
exempt a Person from the limitation on a Person Acquiring Series A Preferred in
excess of the Ownership Limit or Beneficially Owning Series A Preferred in
excess of the Aggregate Stock Ownership Limit if such Person is not an
individual for purposes of Section 542(a)(2) of the Code and the Board of
Directors obtains such representations and undertakings from such Person as are
reasonably necessary to ascertain that no individual's Acquisition or Beneficial
Ownership of such Series A Preferred will violate the Ownership Limit or
Beneficially Owning Series A Preferred in excess of the Aggregate Stock
Ownership Limit, as the case may be, and such Person agrees that any violation
of such representations or undertaking (or other action which is contrary to the
restrictions contained in this Section 8) or attempted violation will result in
such Series A Preferred being exchanged for Series A Excess Preferred in
accordance with Section 8(b).

         (ii) Subject to Section 8(a)(iv), the Board of Directors, in its sole
and absolute discretion, with advice of the Corporation's tax counsel, may
exempt a Person from the limitation on a Person Constructively Owning or
Acquiring Series A Preferred in excess of the Ownership Limit or Beneficially
Owning or Acquiring Series A Preferred in excess of the Aggregate Stock
Ownership Limit if such Person does not and represents that it will not own,
directly or constructively (by virtue of the application of Section 318 of the
Code, as modified by Section 856(d)(5) of the Code), more than a 9% interest (as
set forth in Section 856(d)(2)(B) of the Code) in a tenant of the Corporation
and the Board of Directors obtains such representations and undertakings from
such Person as are reasonably necessary to ascertain this fact and such Person
agrees that any violation or attempted violation will result in such Series A
Preferred in excess of the Ownership Limit or Beneficially Owning Series A
Preferred in excess of the Aggregate Stock Ownership Limit being exchanged for
Series A Excess Preferred in accordance with Section 8(b). 

         (iii) Prior to granting any exception pursuant to Section 8(h)(i) or
8(h)(ii), the Board of Directors may require a ruling from the IRS, or an
opinion of counsel, in either case in form and substance satisfactory to the
Board of Directors, in its sole discretion as it may deem necessary or advisable
in order to determine or ensure the Corporation's status as a REIT; provided,
however, that obtaining a favorable ruling or opinion shall not be required for
the Board of Directors to grant an exception hereunder. 

     (i) Legend. Each certificate for Series A Preferred shall bear 
substantially the following legend:

                                       20
<PAGE>

         "The Corporation will furnish to any stockholder, on request and
without charge, a full statement of the information required by Section 2-211(b)
of the Corporations and Associations Article of the Annotated Code of Maryland
with respect to the designations and any preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications, and terms and conditions of redemptions of the
stock of each class which the Corporation has authority to issue and, if the
Corporation is authorized to issue any preferred or special class in series, (i)
the differences in the relative rights and preferences between the shares of
each series to the extent set, and (ii) the authority of the Board of Directors
to set such rights and preferences of subsequent series. The foregoing summary
does not purport to be complete and is subject to and qualified in its entirety
by reference to the charter of the Corporation including all amendments and
supplements thereto (the "Charter"), a copy of which will be sent without charge
to each stockholder who so requests. Such request must be made to the Secretary
of the Corporation at its principal office or to the Transfer Agent.

         "The securities represented by this certificate are subject to
restrictions on ownership and transfer for the purpose of the Corporation's
maintenance of its status as a real estate investment trust under the Internal
Revenue Code of 1986, as amended. Except as otherwise provided pursuant to the
Charter of the Corporation, no Person may (i) Acquire any shares of Series A
Preferred if, as a result of such Acquisition, such Person shall Beneficially
Own or Constructively Own shares of Series A Preferred in excess of 20% of the
outstanding Series A Preferred of the Corporation or (ii) Beneficially Own or
Constructively Own any shares of Series A Preferred such that such Person would
Beneficially Own or Constructively Own Capital Stock in excess of 9% in value of
the aggregate of the outstanding shares of Capital Stock of the Corporation. Any
Person who Acquires or attempts to Acquire or Beneficially Owns or
Constructively Owns shares of Series A Preferred in excess of the aforementioned
limitations, or any Person who is or attempts to become a transferee such that
Series A Excess Preferred would result under the provisions of the Charter,
shall immediately give written notice or, in the event of a proposed or
attempted Transfer, give at least 15 days prior written notice to the
Corporation of such event and shall provide to the Corporation such other
information as it may request in order to determine the effect of any such
Transfer on the corporation's status as a REIT. All capitalized terms in this
legend have the meanings defined in the Charter of the Corporation, a copy of
which, including the restrictions on transfer, will be sent to any stockholder
on request and without charge. Transfers in violation of the restrictions
described above shall be void ab initio. If the restrictions on ownership and
transfer are violated, the securities represented hereby will be designated and
treated as shares of Series A Excess Preferred which will be held in trust by
the Corporation. The foregoing summary does not purport to be complete and is
subject to and qualified in its entirety by reference to the Charter, a copy of
which, including the restrictions on transfer, will be sent without charge to
each stockholder who so requests. Such request must be made to the Secretary of
the Corporation at its principal office or to the Transfer Agent."

     (j) Severability. If any provision of this Section 8 or any application of
any such provision is determined to be invalid by any federal or state court
having jurisdiction, the validity of the remaining provisions shall not be
affected and other applications of such provision shall be affected only to the
extent necessary to comply with the determination of such court.

     (k) Series A Excess Preferred.

                                       21
<PAGE>

         (i) Ownership In Trust. Upon any purported Transfer (whether or not
such Transfer is the result of a transaction entered into through the facilities
of the NYSE) that results in the issuance of Series A Excess Preferred pursuant
to Section 8(b), such Series A Excess Preferred shall be deemed to have been
transferred to the Corporation, as Trustee of a Trust for the exclusive benefit
of such Beneficiary or Beneficiaries to whom an interest in such Series A Excess
Preferred may later be transferred pursuant to Section 8(k)(v). Series A Excess
Preferred so held in trust shall be issued and outstanding shares of stock of
the Corporation. The Purported Record Transferee shall have no rights in such
Series A Excess Preferred except the right to designate a transferee of such
Series A Excess Preferred upon the terms specified in Section 8(k)(v). The
Purported Beneficial Transferee shall have no rights in such Series A Excess
Preferred except as provided in this Section 8.

         (ii) Dividend Rights. Series A Excess Preferred will be entitled to
dividends and distributions authorized and declared with respect to the Series A
Preferred from which the Series A Excess Preferred was converted and will be
payable to the Trustee of the Trust in which such Series A Excess Preferred is
held, for the benefit of the Charitable Beneficiary. Dividends and distributions
will be authorized and declared with respect to each share of Series A Excess
Preferred in an amount equal to the dividends and distributions authorized and
declared on each share of Series A Preferred from which the Series A Excess
Preferred was converted. Any dividend or distribution paid prior to the
discovery by the Corporation that Series A Preferred has been transferred in
violation of the provisions of the Articles shall be repaid by the Purported
Record Transferee to the Trustee upon demand. The Corporation shall rescind any
dividend or distribution authorized and declared but unpaid as void ab initio
with respect to the Purported Record Transferee, and the Corporation shall pay
such dividend or distribution when due to the Trustee of the Trust for the
benefit of the Charitable Beneficiary. 

         (iii) Conversion Rights. Holders of shares of Series A Excess Preferred
shall not be entitled to convert any shares of Series A Excess Preferred into
shares of Common Stock. Any conversion made prior to the discovery by the
Corporation that shares of Series A Preferred have been converted into Series A
Excess Preferred shall be void ab initio and the Purported Record Transferee
shall return the shares of Common Stock into which the Series A Preferred was
converted upon demand to the Corporation for reconversion into Series A
Preferred and deposit into the Trust. 

         (iv) Rights Upon Liquidation. In the event of any voluntary or
involuntary liquidation, dissolution or winding up of, or any other distribution
of all or substantially all of the assets of the Corporation, each holder of
shares of Series A Excess Preferred shall be entitled to receive, in the case of
Series A Excess Preferred converted from Series A Preferred, ratably with each
other holder of Series A Preferred and Series A Excess Preferred converted from
Series A Preferred, that portion of the assets of the Corporation available for
distribution to its stockholders as the number of shares of the Series A Excess
Preferred held by such holder bears to the total number of shares of Series A
Preferred and Series A Excess Preferred then outstanding (in the case of Series
A Excess Preferred converted from Series A Preferred).

         Any liquidation distributions to be distributed with respect to Series
A Excess Preferred shall be distributed in the same manner as proceeds from the
sale of Series A Excess Preferred are distributed as set forth in Section
8(k)(v).

                                       22

     (v) Non-Transferability of Excess Stock. Series A Excess Preferred shall
not be transferable. In its sole discretion, the Trustee of the Trust may
transfer the interest in the Trust representing shares of Series A Excess
Preferred to any Person if the shares of Series A Excess Preferred would not be
Series A Excess Preferred in the hands of such Person. If such transfer is made,
the interest of the Charitable Beneficiary in the Series A Excess Preferred
shall terminate and the proceeds of the sale shall be payable by the Trustee to
the Purported Record Transferee and the Charitable Beneficiary as herein set
forth. The Purported Record Transferee shall receive from the Trustee the lesser
of (i) the price paid by the Purported Record Transferee for its shares of
Series A Preferred that were converted into Series A Excess Preferred or, if the
Purported Record Transferee did not give value for such shares (e.g. the stock
was received through a gift, devise or other transaction), the average closing
price for the class of shares from which such shares of Series A Excess
Preferred were converted for the ten trading days immediately preceding such
sale or gift, and (ii) the price received by the Trustee from the sale or other
disposition of the Series A Excess Preferred held in trust. The Trustee may
reduce the amount payable to the Purported Record Transferee by the amount of
dividends and distributions which have been paid to the Purported Record
Transferee and are owed by the Purported Record Transferee to the Trustee
pursuant to Section 8(k)(i). Any proceeds in excess of the amount payable to the
Purported Record Transferee shall be paid by the Trustee to the Charitable
Beneficiary. Upon such transfer of an interest in the Trust, the corresponding
shares of Series A Excess Preferred in the Trust shall be automatically
exchanged for an equal number of shares of Series A Excess Preferred and such
shares of Series A Excess Preferred shall be transferred of record to the
transferee of the interest in the Trust if such shares of Series A Excess
Preferred would not be Series A Excess Preferred in the hands of such
transferee. Prior to any transfer of any interest in the Trust, the Corporation
must have waived in writing its purchase rights under Section 8(k)(vii).

     (vi) Voting Rights for Series A Excess Preferred. Any vote cast by a
Purported Record Transferee of Series A Excess Preferred prior to the discovery
by the Corporation that Series A Preferred has been transferred in violation of
the provisions of these Articles shall be void ab initio. While the Series A
Excess Preferred is held in trust, the Purported Record Transferee will be
deemed to have given an irrevocable proxy to the Trustee to vote the shares of
Series A Preferred which have been converted into shares of Series A Excess
Preferred for the benefit of the Charitable Beneficiary. 

     (vii) Purchase Rights in Series A Excess Preferred. Notwithstanding the
provisions of Section 8(k)(v), shares of Series A Excess Preferred shall be
deemed to have been offered for sale to the Corporation, or its designee, at a
price per share equal to the lesser of (i) the price per share in the
transaction that required the issuance of such Series A Excess Preferred (or, if
the Transfer or other event that resulted in the issuance of Series A Excess
Preferred was not a transaction in which the Purported Beneficial Transferee
gave full value for such Series A Excess Preferred, a price per share equal to
the Market Price on the date of the purported Transfer or other event that
resulted in the issuance of Series A Excess Preferred) and (ii) the Market Price
on the date the Corporation, or its designee, accepts such offer. The
Corporation shall have the right to accept such offer for a period of ninety
(90) days after the later of (i) the date of the Transfer or other event which
resulted in the issuance of such shares of Series A Excess Preferred and (ii)
the date the Board of Directors determines in good faith that a Transfer or
other event resulting in the issuance of shares of Series A Excess Preferred has
occurred, if the 

                                       23
<PAGE>

Corporation does not receive a notice of such Transfer or other event pursuant
to Section 8(d). The Corporation may appoint a special trustee of the Trust for
the purpose of consummating the purchase of Series A Excess Preferred by the
Corporation. In the event that the Corporation's actions cause a reduction in
the number of shares of Series A Preferred outstanding and such reduction
results in the issuance of Series A Excess Preferred, the Corporation is
required to exercise its option to repurchase such shares of Series A Excess
Preferred if the Beneficial Owner notifies the Corporation that it is unable to
sell its rights to such Series A Excess Preferred. (l) Settlement. Nothing in
this Section 8 shall preclude the settlement of any transaction entered into
through facilities of the NYSE.

SL Green Realty Corp.
70 West 36th Street
New York, New York 10018

Ladies and Gentlemen:

     This opinion is furnished in connection with the registration, pursuant to
the Securities Act of 1933, as amended (the "Securities Act"), of 4,600,000
shares (the "Shares") __% Series A Convertible , Cumulative Preferred Stock,
liquidation preference $25.00 per share, designated as Preferred Income Equity
Redeemable Shares-SM- ("Preferred Stock"), of SL Green Realty Corp., a Maryland
corporation (the "Company").

     In connection with rendering this opinion, we have examined the Articles of
Incorporation and the Bylaws of the Company; such records of the corporate
proceedings of the Company as we deemed appropriate; a registration statement on
Form S-11 under the Securities Act relating to the Shares, No. 333-50311, as
amended (the "Registration Statement"), and the offering prospectus contained
therein (the "Prospectus") and such other certificates, receipts, records and
documents as we considered necessary for the purposes of this opinion.

     We are attorneys admitted to practice in the States of New York and
Maryland.  We express no opinion concerning the laws of any jurisdictions other
than the laws of the United States of America, the State of Maryland and the
State of New York.  

<PAGE>

     Based upon the foregoing, we are of the opinion that when the Shares have
been issued and paid for in accordance with the terms of the Prospectus, the
Shares will be legally issued, fully paid and nonassessable shares of the
Company's Preferred Stock.



     The foregoing assumes that all requisite steps will be taken to comply with
the requirements of the Securities Act and applicable requirements of state laws
regulating the offer and sale of securities. We hereby consent to the filing of
this opinion as an exhibit to the Registration Statement and the reference to

SL Green Realty Corp.
70 West 36th Street 
New York, New York 10018-8007

Ladies and Gentlemen:

     You have requested our opinion concerning certain of the federal income tax
consequences to SL Green Realty Corp. (the "Company") in connection with the
proposed transactions described in the prospectus included as part of the Form
S-11 Registration Statement (No.333-50311) of the Company initially filed by the
Company with the Securities and Exchange Commission on April 16, 1998, as
amended through the date hereof (the "Registration Statement").

     This opinion is based, in part, upon various assumptions and
representations, including representations made by the Company as to factual
matters set forth in the discussion of "Material Federal Income Tax
Consequences" in the Registration Statement.  This opinion is also based upon
the Internal Revenue Code of 1986, as amended (the "Code"), the Treasury
Regulations promulgated thereunder and existing administrative and judicial
interpretations thereof, all as they exist at the date of this letter.  All of
the foregoing statues, regulations and interpretations are subject to change, in
some circumstances with retroactive effect.  Any changes to the foregoing
authorities might result in modifications of our opinions contained herein. 
Based on the foregoing, we are of the opinion that:

     (1)  Commencing with the Company's taxable year ended December 31, 1997,
the Company was organized in conformity with the requirements for qualification
and taxation as a real estate investment trust (a "REIT") under the Code and the
proposed method of operation of the Company will enable the Company to meet the
requirements for qualification and taxation as a REIT.

     (2)  The discussion in the Registration Statement under the caption
"Material Federal Income Tax Consequences" summarizes the federal income tax
considerations that are likely to be material to a holder of the Company's
Series A Convertible Cumulative Preferred Stock (referred to on the Registration
Statement as the PIERS).

<PAGE>

     We express no opinion with respect to the transactions described herein and
in the Registration Statement other than those expressly set forth herein. 
Furthermore, the Company's qualification as a REIT will depend on the Company's
making a timely election for REIT status and meeting, in its actual operations,
the applicable asset composition, source of income, shareholder diversification,
distribution, recordkeeping and other requirements of the Code and Treasury
Regulations necessary for a corporation to qualify as a REIT.  We will not
review these operations and no assurance can be given that the actual operations
of the Company and its affiliates will meet these requirements or the
representations made to us with respect thereto.

     This opinion is furnished to you solely for your use in connection with the
Registration Statement.  We hereby consent to the filing of this opinion as
Exhibit 8.1 to the Registration Statement and to the use of our name under the
caption "Material Federal Income Tax Consequences" in the prospectus included
therein.

                                                       Very truly yours,

The New York Metropolitan Economy

SUMMARY

Strong growth of the national economy has benefited New York City, causing
growth in the New York metropolitan economy to accelerate significantly in
recent years.*  In fact, in November of 1997, FORTUNE magazine ranked New York
as the most improved city for business in North America.  Also in 1997, INC.
Magazine recognized New York City as the city with the largest number of
growing, privately-held companies.  Manhattan is one of the worlds most
important business centers.  As the headquarters of 46 Fortune 500 companies,
Manhattan is home to more Fortune 500 companies than any other city in the
country.  In addition to its diverse base of large businesses, Manhattan also
has a large base of small companies. The New York City Office of the Comptroller
reports that 99.7% of all private sector businesses in New York City had fewer
than 500 employees and that these small businesses, representing 70.7% of the
private sector work force, added a net total of 42,000 jobs between the third
quarters of 1996 and 1997.  Sixty-four of the 100 largest law firms in the
country have a presence in Manhattan, and 27 of those are based there.  Four of
the Big Five accounting firms are headquartered in Manhattan, and three of the
four largest U.S. commercial banks ranked by assets are based in Manhattan.  In
addition, three of the nations ten largest money managers and 23 of the 25
largest securities firms are based in Manhattan.  New York City is one of the
worlds leading cultural centers.  It is a world leader in the advertising and
publishing industries, and it has a large base of nonprofit organizations.  It
also has the largest consulate community in the world, contributing to its
position as an international center of business an politics.

THE OUTLOOK IN THE NEW YORK METROPOLITAN AREA IS FOR HEALTHY PRIVATE SECTOR
EMPLOYMENT GROWTH THROUGH 2002, WHICH SHOULD GENERATE SIGNIFICANT DEMAND FOR
OFFICE SPACE.  Within Manhattan, Mayor Giuliani's efforts to improve services,
reduce taxes and crime, and streamline local government have made this vibrant
24-hour city more attractive to businesses.  In addition, office rents in
Manhattan are relatively inexpensive when compared internationally with other
major cities.  In July of 1997, Richard Ellis Company ranked Midtown Manhattan
13th among major business centers around the world in terms of office occupancy
costs, while downtown Manhattan ranked 31st.  Many businesses are expanding
within Manhattan or opening local offices, and a number of companies have made
long term commitments to Manhattan by purchasing buildings or signing long term
leases.  The emergence of the new media industry is another major boon for
Manhattan because these jobs have a high multiplier effect, generating jobs in
related industries, particularly in the services sector. 

ECONOMIC OVERVIEW

Economic growth in the New York metropolitan statistical area (MSA) has
strengthened during the past several years.  Private sector employment gained an
average of almost 50,300 jobs per year during the four years between 1994 and
1997 for an average annual growth rate of 1.6%.  BETWEEN FEBRUARY OF 1997 AND
1998, PRIVATE SECTOR EMPLOYMENT GROWTH WAS 2.3%, WHICH IS THE STRONGEST GROWTH
RATE IN MORE THAN TEN YEARS.  This 2.3% private sector growth rate represents
the addition of about 74,200 jobs (see Figure 1 and Tables 1 and 2).  The New
York MSA led the Northeast and 

<PAGE>

ranked eighth in the nation in terms of the number of jobs created in
metropolitan statistical areas with more than 250,000 jobs during the twelve
months ended in February of 1998.  The metropolitan area offers several key
competitive advantages, including access to a skilled work force, customers,
partners and investors, that make it a strategically advantageous place to do
business and which drive private sector employment growth.  Similar to each of
the prior economic cycles, the New York metropolitan areas economy is going
through a re-engineering process, characterized by the emergence of several
dynamic new industries and the streamlining of older industries, including the
public sector.  It is primarily knowledge-based industries, such as the
securities industry, the new media industry and overall business services, that
are benefiting from the areas key strengths.  Growth in these industries, in
turn, is fueling expansion in other sectors of the economy.

The vibrancy of New York City is a function of more than job growth.  With about
8.6 million people in 1997 (including 7.4 million in New York City), the
metropolitan area ranks second only to Los Angeles in terms of population.  Many
New Yorkers are highly educated.  According to the 1990 Census, about 42% of the
population over the age of 25 in New York County had a bachelors degree and
almost half of those had a graduate or professional degree, rates that are well
above the national average.  Manhattan is also a cultural hotspot, with many of
the nations and worlds leading restaurants, museums, and a rich concentration of
theater and performing arts.  Because of the large number of people living and
working in such a small area, activity occurs around the clock, making New York
a 24-hour city.

From a quality of life perspective, Mayor Giuliani's efforts to improve city
services, reduce taxes and crime, and streamline city government are paying off.
Crime is down dramatically in New York City, particularly compared to national
crime trends (see Figure 2).  RCG estimates of per capita crimes based on 1996
population for cities and crimes reported during the first half of 1997 indicate
that New York City ranked 151st out of 182 markets with more than 100,000
people.  New York City ranked lower than Las Vegas (1), Atlanta (3), Miami (5),
Phoenix (40), and Milwaukee (84).  According to the New York City Police
Department, New York City's crime rate decreased a cumulative 44% between 1993
and 1997, including a 9% drop during 1997.  Several factors are contributing to
this decline, including increased drug enforcement efforts and police
redeployment to problem areas.  The drastic reduction in crime has been a boon
to the tourism industry, which has experienced strong gains in visitor volume,
spending and hotel occupancy.  IN TURN, REDUCED CRIME AND MORE TOURISM ACTIVITY
HAS STIMULATED AFTER-BUSINESS-HOURS ACTIVITIES SUCH AS THEATER, DINING AND
CLUBS, REINFORCING NEW YORK'S REPUTATION AS A 24-HOUR CITY. 

Chart 2
(Chart regarding New York City Crimes Reported (per thousand inhabitants) from 
1950 through 1997)

Much of the recent job growth has occurred at small companies, defined as
businesses with fewer than 500 employees.  According to New York City's Economic
Development Corporation, the city experienced a net gain of 3,611 small
businesses in 1996 alone.  The Giuliani administration has also successfully
retained more than 35 major companies through its corporate retention program,
including Reuters and Bear Stearns.  According to the New York City Office of
the Comptroller, between 1984 and 1995, small businesses added 43,034 jobs,
while large businesses lost 103,112 jobs.  Growth in recent years has been the
strongest.  Between the third quarters of 1996 and 1997 (the most recent period
for which data is available), small businesses gained 42,000 jobs. About 

                                          2
<PAGE>


99.7% of the businesses in New York City are small businesses.  About 90% of
these small businesses employ fewer than 20 people, about 6.3% employ 20 to 50
people, 2.1% employ 50 to 100 people, and only 1.6% employ 100 to 500 people. 
Many of these small businesses occupy Class B office space.  During 1996, 47% of
the Class B leasing activity in Manhattan was for blocks of space of less than
20,000 square feet, illustrating the strong demand for Class B space by smaller
tenants.

The Services Sector

Job growth is strongest in the services sector.  The services sector grew at
strong rates of about 3.7% in 1996 and 1997, and most recently, during the
twelve months ended in February of 1997, the services sector gained 3.5%, for
the addition of about 50,000 jobs.  With nearly 1.5 million jobs, the services
sector currently represents 38% of the New York metropolitan areas total
employment base and 44% of its private sector employment base.  Between 1992 and
1997, about 202,000 new jobs were created in the services sector (see Figure 3).

One of the largest components of the services industry is business services,
with about 307,000 jobs as of February 1998, representing 21% of total services
employment.  Fueling growth in the business services sector are the advertising
industry, the increased demand for computer programmers including Web
programmers, designers and writers, as well as the rend towards hiring temporary
workers as a way to maintain corporate flexibility and, thus, to lower payroll
costs.  New York City's Madison Avenue dominates the worlds advertising
industry.  Agencies in New York account for about half of all advertising
billings worldwide, and about one of every three advertising professionals in
America works in New York City.  Other components of the business services
sector are the audio recording and the software industries. Accordingly, the
entertainment and information technology industries contribute to the rapid
growth within business services.  Between 1992 and 1997, growth in business
services averaged a robust 4.9% per year, and between February of 1997 and 1998,
business services grew 7.3% (see Table 3).

(Bar chart regarding Absolute Change in Services Employment for the New York MSA
from 1971 through 1997)

Table 3
(Table regarding New York MSA Services Sector Employment from 1989 through
February 1998)

An important component of growth is the new media industry.  New media is a
cross-disciplinary industry combining elements of computing technology,
telecommunications and media content to create products and services for
consumers and businesses.  The companies working in this industry include
entertainment software, online/Internet services, CD-ROM title developers, and
web site designers.  In addition, advertising, publishing, television
broadcasting, recording industry, retailing, financial services and most other
industries, participate in the sector by creating demand for its products.  More
than 2,600 new media companies have a presence in new York City, ranging from
small start-ups to large companies.  These companies locate in New York because
of the available work force with the necessary skills and the nearby presence of
many industries that are fostering its growth.  According to the State Deputy
Comptroller for New York City, employment in this sector has nearly doubled in
size to just over 30,000 in 1997 from just over 15,000 in 1993.  Wages in this
sector at nearly $69,000 are 20% higher than the average private sector wage. 
As the new media industry grows, it has a multiplier effect on other industries,
including venture capital firms and investment banks.  In the first two quarters
of 1997, venture capital firms invested $149 million in local software companies
compared to $80 million in the same period of 1996.  Communication firms 

                                          3
<PAGE>

received an additional $77 million in venture capital investment in the first
half of 1997.  Strong growth in the new media industry is having a major
multiplier effect for the overall New York economy.  THE DIRECT BENEFITS OF
GROWTH IN THIS INDUSTRY WILL FLOW TO BUSINESS SERVICES AND TO THE BROADCAST,
PUBLISHING AND ADVERTISING INDUSTRIES, ALL OF WHICH ARE CONCENTRATED IN
MANHATTAN.

Other important components of the service sectors are legal services,
engineering and management services and membership organizations.  Together,
these three subsectors added about 7,200 jobs between February of 1997 and 1998,
many of which occupy office space (see Table 4).  Legal services is the third
most highly concentrated industry in the New York metropolitan area (see Table
5).  According to the NATIONAL LAW JOURNAL, 64 of the 100 largest law firms have
a presence in Manhattan, and 27 of those firms are based in Manhattan.  In
addition, hundreds of other domestic and international law firms are located in
Manhattan.  In the engineering and management services sector, four of the Big
Five accounting firms have their national headquarters in Manhattan, and many of
the worlds foremost management consulting firms are located in Manhattan.  In
addition, about 20,000 nonprofit organizations are based in New York City,
ranging from cultural groups and trade associations to research facilities.

1989 through February 1998)

concentration of employment in a particular industry))

Motion pictures and entertainment are other highly concentrated industries in
the New York metropolitan area.  These are export-oriented industries that have
a large multiplier affect on the local economy.  Among the largest employers in
New York City are several major media and broadcasting companies, including Time
Warner, Westinghouse Electric, which owns CBS, and Walt Disney Company, which
owns Capital Cities/ABC (see able 6).  Six of the top ten music recording
companies are also headquartered in New York City.  New York City has taken
efforts to spur growth in motion pictures and entertainment.  For example,
legislation was passed in 1996 to eliminate the city's 4% sales tax on film and
television production consumables and equipment rentals.  The motion picture
industry alone added 19,800 new jobs between 1992 and 1997 in the New York MSA,
representing stunning growth averaging 13.8% per year.

The amusement and recreation services sector and hotel and lodging industry both
benefit from tourism and visitor spending.  New York has a plethora of theater
and performing arts, which fuels growth in amusement and recreation.  It is home
to more than 150 museums, including some of the worlds most famous museums like
the Metropolitan Museum of Art, the Museum of Modern Art, the Guggenheim Museum,
the Whitney Museum and the Museum of Natural History.  In the tourism industry,
about 31.9 million people visited New York City during 1997, up from 31.3
million in 1996, according to the New York Convention and Visitors Bureau. 
Visitor spending rose 5.4% to about $13.7 billion in 1997, representing roughly
4% of the gross city product of $340.7 billion.  Visitor volume and spending has
benefited substantially from the dramatic decline in crime in New York City in
recent years.  Reflecting the strength of visitor spending, the hotel and
lodging industry is enjoying strong revenue growth.  Hotel occupancy was up to
82% in 1997 from 78.6% in 1995, and the average daily room rate rose 16% to $181
during the two year period (see Figures 4 and 5).  The number of hotel room
nights filled grew from 14.8 million in 1993 to 18 million in 1997, representing
a gain of 5% per year (see Figure 6).  Growth has been constrained by the lack
of available rooms.  New York City has 60,000 rooms, and only 1,000 rooms are
under construction, although 5,000 

                                          4

more could be delivered by 2001.

Table 6
(Table regarding New York City's Top Employers by Employees)

While health, social and educational services are mainly population-serving and
thus do not create many office-occupying jobs, they contribute to growth in New
York's economy.  Health services added about 3,600 jobs between February of 1997
and 1998, even though growth in this sector has been tempered in recent years by
restructuring in the City's public and private health industry. Among the
leading medical facilities in Manhattan area Columbia-Presbyterian and Cornell
Medical Centers and Memorial Sloan-Kettering Cancer Center.  Manhattan is also
home to several internationally recognized universities, including Columbia
University, New York University, Rockefeller University and Fordham University. 
These and other local institutes graduate thousands of students each year,
creating a large, high-level professional talent pool for New York employers.

The Trade Sector

Following services, the trade sector is the next largest source of new jobs in
the New York metropolitan area, with the addition of 13,800 jobs during the
twelve months ended in February of 1998 for a 2.1% growth rate.  About 68% of
the metropolitan areas trade jobs are in the retail sector, where growth was an
even stronger 2.4% during the twelve months ended in February of 1998.  New York
City is a hub for retail trade.  The retail industry has benefited from improved
city services, reduced crime and an increase in the number of visitors and their
spending volume.  The improved health of the New York economy has stimulated
spending by locals.  About 96,300 households have effective buying income
exceeding $150,00 per year.  Thus, many New York City residents have significant
disposable income with which to purchase goods and services.  According to the
State Deputy Comptroller, increased spending by locals combined with a higher
level of visitor spending caused sales tax collections to increase 6.5% during
1997 compared with 5.8% in 1996.  Approximately half of sales tax revenues are
from the retail sector (see Figure 7).  

Chart 7
(Chart regarding New York City's Sales Tax Collections from 1989 through 1998)

Attesting to the strength of the retail trade sector, a number of retailers are
expanding in New York City and are adding new employees.  Not only are big box
discount retailers establishing a niche, but upscale designers are opening
outlets.  Kmart has opened several stores, and upscale designers and
manufacturers, such as Calvin Klein, Armani and Valentino, have also opened
retail stores.  Retail development is also moving into the downtown and Times
Square areas.  In downtown, Borders Books and Music has a new store in the World
Trade Center, and in the Times Square area, Forest City/Ratner is building a
325,000 square-foot project that will contain a 25-screen AMC multiplex and a
Madame Tussaud's Wax museum.  Near this project, the 1,839-seat Ford Center for
Performance Arts recently opened, while Disney has redeveloped the New Amsterdam
Theatre and opened a flagship store.  Warner Brothers plans to create a
multi-level retail space across the street from Disney's flagship store.  Also
in the Times Square area, Tishman Urban Development is building the 193,000
square-foot E-Walk retail complex in Times Square, and as part of he E-Walk
project, Disney plans to build a 45-story hotel.  Also contributing to the
renewed vitality of Times Square, ABC has leased studio and office space and
plans to use Times Square as a backdrop for various news and sports programs,
and ESPN is considering creating a 35,000 square-foot restaurant with a
screening room for sports events at 1500 Broadway.  The entire 42nd Street and
Times Square 

                                          5
<PAGE>

Development Project is estimated to eventually create 35,000 permanent jobs.  

Growth in wholesale trade has also improved, with a most recent 1.3% gain
between February of 1997 and 1998.  Contributing to this growth is increased
activity at New York Harbor.  Fueled by a strong economy and reduced shipping
fees, the harbor handled nearly 12% more cargo traffic during the first half of
1997, compared with the same period in 1996.   The improvement is a sign that
lower labor costs, an overhaul of the harbor and docks, and an aggressive
marketing effort are paying off.

The Finance, Insurance and Real Estate (FIRE) Sector 

Following several years of acquisitions and mergers in the commercial banking
industry, employment in the metropolitan areas FIRE sector has turned the
corner, with a 0.6% gain in 1997 and a 1.1% gain between February of 1997 and
1998.  Half of New York City's top 23 employers are financial institutions (see
Table 6).  According to PENSIONS AND INVESTMENTS magazine, three of the ten
largest money managers in the United States, ranked by total assets, are based
in Manhattan, and the Securities Industry Association reports that 23 of the 25
largest U.S. securities firms are based in Manhattan.  In addition, according to
THE AMERICAN BANKER, three of the nations top four commercial banks ranked by
assets are base in Manhattan.

Consolidation has occurred among some FIRE sector industries, including
commercial banks and insurance companies.  Large commercial banks are facing
increased competition with non-bank institutions that now offer bank-like
depository and lending services.  They are also encountering the Asian financial
crisis and necessary investments in new technologies.  Several large banks,
including J.P. Morgan & Co., Citicorp and Chase Manhattan Bank, have announced
plans to consolidate their work forces worldwide.  Because the losses will be
spread around the world, we do not expect the effect on New York City employment
and demand for office space to be significant.  ON A POSITIVE NOTE FOR THE FIRE
SECTOR, THE CONSOLIDATION OF COMMERCIAL BANKS IN RECENT YEARS HAS CREATED A MUCH
MORE COMPETITIVE SET OF PLAYERS IN NEW YORK CITY, AND IN SOME CASES,
CONSOLIDATION OF FIRE SECTOR EMPLOYERS HAS TRANSLATED TO NEW JOBS FOR NEW YORK
CITY.  Other companies in the FIRE sector, specifically international banks, are
increasing their presence in Manhattan and have hired aggressively on a local
basis.  More than 400 international banks have a presence in New York City.

The securities industry represents 4% of the overall employment base in the
metropolitan area.  Although it represents only a small part of the economy,
this industry is highly concentrated in the New York metropolitan area, and many
of the world's most active underwriters are based in Manhattan or have a strong
presence there.  Wall Street accounts for 15% of the city's total wages. 
Because per person wages on Wall Street average $150,000, the multiplier effect
of these jobs on other employment sectors is large.  The number of jobs in the
securities and commodities brokers employment sector in the New York
metropolitan area increased an average of 3.2% per year between 1991 and 1997,
rising from a recession trough of 131,500 in 1991 to 162,500 jobs in February of
1998.  Growth in this industry has played a significant role in the metropolitan
areas recovery.  

                                          6
<PAGE>

The securities industry has been very strong, and the recent acceleration of
initial public offerings and other investment banking activities should lead to
additional growth in this industry.  In the short term, the reduced size of the
industry, relative to the previous peak, and the high level of demand for Wall
Streets products and services will buffer the impacts of a possible stock market
correction and slower growth.  In the long term, both the finance and securities
industries will contribute to local economic growth because of New York's
position as an international center of finance and securities innovation.

The Transportation, Communications, and Public Utilities (TCPU) and
Manufacturing Sectors

Employment in the New York metropolitan areas transportation, communications and
public utilities (TCPU) sector increased 0.6% between February of 1997 and 1998.
New York City is a center for the television, cable, radio, recording and
publishing industries.  In addition to serving as the headquarters for the
nations four major television networks, more than 20 cable television companies,
including A&E and MTV, are headquartered in New York City.  The communications
part of this sector has been affected by the merger of several Bell operating
companies across the nation, the merger of cable and entertainment firms, of
publishers and broadcasters and of broadcasters and entertainment firms.  Some
of the mergers have resulted in new jobs for the New York metropolitan area as
companies consolidate operations from other cities.  For example, the combined
Bell Atlantic and Nynex is headquartered in New York City.  Increasing
competition in telecommunications has created new jobs in New York as both
established and new companies seek to capture market share. 
Telecommunications-related employment is also growing as industries such as
financial services increase their usage of phone lines for on-line
communication.  

The New York metropolitan area has gradually shed manufacturing jobs.  Because
New York is an urban center with high operating costs and difficult
transportation access, it is an unfavorable site for manufacturing, and many
traditional manufacturers have relocated.  Both textiles and publishing have
moved out of the city.  Many manufacturing firms have returned a large volume of
industrial space to the market, with such space gradually being converted to
office or residential uses.  An increasing proportion of the manufacturing jobs
in New York are actually white-collar management or staff positions.

The Public Sector

New York City's government is reinventing itself. About 78% of the metropolitan
areas total government employment is in local government, and the remaining 22%
is state and federal government employment.  Intense efforts to streamline the
government and to provide services more efficiently have caused local government
employment to decline by about 63,400 jobs, or 11.9%, between 1990 and February
of 1998. 

The strong growth in private sector employment, coupled with a much more
disciplined approach to city services and expenditures, have resulted in both a
greatly improved outlook for New York City's budget and higher quality of city
services.  The city ended fiscal 1997 with $1.3 billion in excess 

                                          7
<PAGE>

revenues, a much larger surplus than the anticipated $856 million.  The
additional revenues were slated to be used to prepay debt service for 1998 and
1999.  Since the adoption of the 1998 budget, the city has forecast $3.1 billion
in additional revenues, most of which will be set aside to reduce out-year gaps.
 Part of the excess will also be used to reduce taxes further.  In recent years,
New York City and State has eliminated the hotel occupancy tax, the so-called
Cuomo  transfer tax, taxes on proprietorships and partnerships, and reduced the
commercial rent tax.  The most recent tax reduction effort is the new measure
that will reduce the Unincorporated Business Tax effective in July of 1998.
Additional proposed tax cuts include elimination of sales tax on all clothing
and footwear beginning in December of 1998, phased-in elimination of the
remaining commercial rent tax, property tax relief for Co-op and condominium
owners, personal income tax child care credit, and the elimination of subchapter
S  corporation tax.  Reflecting the improved outlook, in February of 1998,
Moody's Investors Service upgraded New York City's General Obligation credit to
A3 from Baa1.


THE OVERALL BUSINESS CLIMATE IN NEW YORK HAS IMPROVED SIGNIFICANTLY AS A RESULT
OF BOTH PRIVATE SECTOR INITIATIVES AND PUBLIC SECTOR PROGRAMS.  The most visible
private sector initiatives have been the Business Improvement Districts (BIDs). 
A BID is formed by a group of employers in a geographic area with the express
purpose of improving the business environment in the area through heightened
security, improved street cleaning and lighting and other business-enhancing
services.  Following on the success of three large BIDs in the Grand Central
Terminal, Penn Station and Times Square areas, approximately 36 additional BIDs
in New York City have been created, including the Downtown-Lower Manhattan
Business Improvement District with an annual budget of $8.6 million. 

In addition, a number of public sector efforts have been launched to improve New
York City's business environment, specifically to retain the existing base of
employers and attract additional employers.  For example, the Giuliani
administration and New York City's Economic Development Corporation have helped
retain more than 35 major companies with 79,700 jobs in recent years.  These
companies will produce more than 40,000 additional jobs as they expand in the
city. 

New York also has a large diplomatic community, affiliated with the United
Nations and local consulates.  A report published by the New York City
Commission for the United Nations and Consular Corps reported that the United
Nations Headquarters, Agencies, Missions and Consulates spent about $1.5 billion
in the New York metropolitan area during 1994 with an indirect impact of $3
billion.  New York City also hosts the largest Consulate community in the world,
which attracts private sector foreign businesses.  The large diplomatic
community contributes to New York's position as an important international
center of business and politics.  

EMPLOYMENT OUTLOOK

The current economic expansion in New York City is robust because the city's
economy has become more diverse and thus less dependent on financial services. 
While Wall Street still plays an important role in generating the high profits
and commensurate salaries and bonuses that result in spending and tax revenue
growth, it has not contributed significantly to job growth.  The streamlining in
government, banking, publishing, accounting and other core industries has
resulted in stronger 

                                          8
<PAGE>

organizations better suited to face the opportunities and risks of the next
century.  At the same time, the emergence of the dynamic new media/Internet
industry has established fast-growing start-up firms and fast-growing
departments in established firms across many industries.  

The outlook for the New York metropolitan economy during the next five years is
strong.  Following 2.1% growth in 1997, we believe that private sector
employment in the metropolitan area will gain 1.8% in 1998, representing the
addition of about 61,700 jobs.  Growth will drop to the 1.3% range in 1999 and
2000, before accelerating again in 2001 and 2002 (see Table 7).  Altogether,
about 258,000 jobs will be created during the five year forecast horizon.  The
strong growth of the national economy will fuel activity in the finance sector,
which includes the securities industry.  However, much of the growth will
continue to occur in the services sector, especially in industries such as
advertising, law, software, motion pictures, hotels and tourism.  Strong growth
in small businesses, such as those in the new media  industry, will further
enhance the growth prospects for business services and, generally, other
industries which provide services to businesses.

THE OFFICE MARKET 

Summary

Manhattan is the largest office market in the country, with an overall stock of
almost 380 million square feet in the Midtown, Midtown South and Downtown
submarkets.  The amount of space in Manhattan exceeds the combination of the
next six largest central business districts in the nation, those of Chicago, the
District of Columbia, Boston, San Francisco, Philadelphia and Los Angeles (see
Table 8).  Within Manhattan, 45.3% of the space is classified as Class B space
(see Table 9).*  About 75% of the Class B space is located in the Midtown and
Midtown South submarkets combined, and about 25% of the Class B space is located
in Downtown.**  

Table 8
(Table regarding 1997 Comparative Downtown Office Stocks)

Table 9
(Table regarding Manhattan Office Market Overview showing Class A and B stock,
Class A and B 1st quarter Vacancy Rates and 1st Quarter Rents per square foot,
for different areas of Manhattan)

Accelerating job growth in recent years, resulting from the recovery of the
national and New York metropolitan economies, has caused office market
conditions in Manhattan to strengthen.  The overall Class B vacancy rate fell
from 17.7% in 1992 to 11.9% in the first quarter of 1998, a rate that is only
moderately higher than the Class A vacancy rate of 9.3% (see Table 10).  At
9.7%, Midtown has the lowest Class B vacancy rate, followed by Midtown South,
with a 10.1% Class B vacancy rate.  When combined, the second quarter 1997 Class
B vacancy rate for Midtown and Midtown South is 9.8%.  In recent years, demand
in the Midtown area has come from existing Midtown Manhattan businesses that are
expanding, as well as some traditional Downtown tenants which have moved to
Midtown in search of greater amenities and improved access to transportation. 
However, much of the available space in Midtown has been absorbed.  The
escalating rent differential between Class A and Class B space, as well as
between Midtown and Downtown space, is causing some tenants to increasingly
consider Class B space, especially Downtown.  The limited availability of Class
A space in Midtown is also causing tenants to consider Class B space in Midtown
and/or Downtown options.  

Table 10
(Table regarding summary of Manhattan Office Market Vacancy Rates for 1992
through the forecast for 2002)

During the next several years, overall market conditions will tighten further. 
AS CLASS A RENTS RISE AND SPACE BECOMES MORE SCARCE, WE ANTICIPATE THAT DEMAND
FOR CLASS B SPACE WILL INCREASE, ESPECIALLY IN BUILDINGS WITH MODERN
INFRASTRUCTURE AND GOOD LOCATIONS, BUT WHICH OFFER RENTS THAT ARE LESS EXPENSIVE
THAN THOSE IN THE CLASS A MARKET.  Additional demand, combined with limited new
construction during the next several years, leads us to believe that the overall
Manhattan Class B vacancy rate will fall to 8.7% by 2002 and that the Class B
vacancy rate in the combined area of  Midtown and Midtown South will fall to
7.0% by 2002 (see Table 11).  

Table 11
(Table regarding Manhattan Class B Office Market Trends from 1992 through the
forecast for 2002)

Demand Analysis

In order to capture the actual demand in the Manhattan Class B office market, we
have utilized three measures (see Table 12).  The first is GROSS LEASING
ACTIVITY, which involves summing up all the leases signed in the market.  This
measures all leases, including renewals of existing leases and relocations
within the market and, as a result, may lead to some double counting of space. 
It also includes pre-leasing of space in new buildings.  However, it is a good
measure of the overall health of the office marketplace.  A second measure,
derived from the vacancy rate, is CALCULATED NET ABSORPTION.  Calculated net
absorption is a constructed data series created by examining the change in
occupied 

<PAGE>

stock.  The change in occupied stock, in turn, is created by multiplying the
occupancy rate (1-vacancy rate) by the total stock of space.  It must be
emphasized that this is a constructed  data series to approximate historical net
absorption.  It is the best measure of net demand for office space.  The third
measure of office space demand is constructed from employment growth and is used
to forecast office space demand.  Specifically, job growth by office-using
sectors  is multiplied by an office space utilization factor, in this case 200
square feet per person for Class B space and 175 square feet per person for
Class A space, to produce a FORECASTED NET ABSORPTION of office space.  All
three measures of demand, gross leasing activity, calculated net absorption, and
forecasted net absorption, must be viewed as proxies for demand because there
are no official  numbers to measure demand.

Table 12
(Table regarding Calculated/Forecasted Net Absorption and Gross Leasing Activity
Summary from 1993 through the forecast for 2002)

As Figures 8 and 9 show, gross leasing activity in Manhattan has increased
during the past several years.  Between 1993 and 1996, gross leasing activity
for the overall office market averaged 25 million square feet per year, rising
to 32 million square feet in 1997.  Activity during the first quarter of 1998
indicates that this year will be another very strong year for leasing activity,
reflecting the health of the Manhattan office market.

1993 through the 1st quarter of 1998)

Chart 9
(Bar Chart regarding Gross Leasing Activity for Manhattan Class B office from
1993 through the 1st quarter of 1998)

Gross leasing activity and net absorption are strongest in Midtown, but are
increasing in both Downtown and Midtown South (see Figures 10 to 17).  Some
traditional downtown tenants, such as banks and securities firms, have moved to
Midtown locations because of their perceptions that Midtown amenities, such as a
location that is more easily accessible to many employees, outweigh the cost
savings of Downtown locations, although this trend is reversing because of the
lack of available space in Midtown and the increasing popularity of Downtown as
a place to live and work.  In all of Midtown, only 15 Class A and six Class B
blocks of space greater than 150,000 square feet were being marketed in March,
including space at yet-to-be finished buildings like Four Times Square.  Tenants
generating strong demand for Midtown office space include those in the
advertising, printing and publishing, legal services, and communications
industries.  Among the largest leases during 1997 were McGraw-Hill at Two Penn
Plaza, Chase Manhattan Bank at 1211 Sixth Avenue, and ING Capital Markets at 55
East 52nd Street.

In Midtown South, gross leasing activity and net absorption strengthened during
1997 and into 1998, causing vacancy rates for both Class A and B space to fall. 
Midtown South is largely a market of Class B space.  It is becoming more
desirable because it offers less expensive office space than Midtown and an
improving quality of life as older buildings are renovated and neighborhoods
improve.  In fact, Class B space in the Midtown South area with good
infrastructure is performing better than the overall Class B market.  In
addition to its traditional base of small companies,  Midtown South is
increasingly attracting back office operations and even primary office
operations of companies that are finding it difficult to locate large blocks of
contiguous space in Midtown.  For instance, three new and expanding tenants
during 1997 at 11 Madison Avenue, including Price Waterhouse, Credit Suisse
First Boston, and Metropolitan Life Insurance, brought the building to almost
full occupancy.  Also in Midtown South, Penguin Books leased space at 345 Hudson
Street and at 375 Hudson Street.  As buildings such as 11 Madison Avenue are
renovated to accommodate these name  tenants, they have been upgraded to Class A
space, a trend we expect to continue.  In addition, moves by these name tenants
are spurring other tenants to consider Midtown South 

                                          2
<PAGE>

locations.  In March of 1998, only seven blocks of Class B space and no Class A
space of more than 150,000 square feet were available.

Efforts to revitalize Downtown New York are paying off with sharply increasing
demand for office space.  A number of incentives have been created to attract
tenants downtown.  For example, the Downtown Commercial Revitalization Program
offers a mix of commercial rent tax, real estate tax, and energy expense relief
to tenants who sign new or renew leases in buildings constructed before 1975. 
Tenants are drawn downtown by lower rents and the lack of large blocks of
contiguous space elsewhere in Manhattan.  In addition, the downtown resident
population is increasing as older, obsolete buildings are converted to
residential use and new projects are being built, such as those at Battery Park
and Riverside South.  Encouraging these conversions are financial incentives
that are part of the Downtown revitalization program.  The Alliance for Downtown
New York estimates that 5,000 units will be created from conversion over the
next ten years.  Among the residential conversions completed and  underway are
127 John Street, 56 Beaver Street, 25 Broad Street, 67 West Street and 18 Murray
Street.  Not only do residential conversions eliminate older, obsolete office
space from the inventory, but as old office space is converted to residential
uses, Downtown is becoming more of a 24-hour city.  Shopping and entertainment
options are also increasing, with the redevelopment of the Chelsea Street Piers
and other retail projects.  As a result, Downtown is becoming more attractive to
office users.  

Demand for Downtown space has increased notably among the traditional financial
services, insurance and banking tenants, as well as high-tech, government and
nonprofit organizations.  For example, in 1997s largest lease transaction,
McGraw-Hills Standard & Poors unit leased 937,000 square feet for 20 years at 55
Water Street.  Other notable downtown leases have been signed by Empire Blue
Cross Blue Shield, Guardian Life Insurance, the Human Resources Administration
of New York City, and Merrill Lynch.  Numerous new media and high tech companies
have leased space at 55 Broad Street, which has been transformed into the New
York Information Technology Center, and beginning in early 1997, a public
private partnership between the Alliance for Downtown New York, property owners,
and the City of New York began developing Plug n Go space in Downtown office
buildings to provide space for high technology start-up companies.  The Plug n
Go properties are pre-wired for Internet use, and are located in the same
general area, creating a high technology start-up community.  Tenants receive
simplified leases and rebates of up to half of the real estate taxes. 
Illustrating the strength of the market, in March of 1998, eight blocks of Class
A space and 13 blocks of Class B space greater than 150,000 suare feet were
being marketed Downtown, including some projects that are being renovated and
are not currently available for move in.

During 1997 and into 1998, Downtown rent growth has accelerated.  The Class A
vacancy rate has dropped notably, although the Class B vacancy rate has yet to
show significant improvement (see Table 13).  Going forward, Downtown office
market conditions will strengthen as obsolete space is renovated and converted
to other uses.  We expect the Downtown Class B vacancy rate to fall to 14.0% in
2002 and Downtown rent growth to accelerate to 4.2% per year by 2002.    

Table 13
(Table regarding Downtown Manhattan Class B Office Market Trends from 1992
through the forecast for 2002)

In recent years, strong growth in business services and the stabilization of the
commercial banking industry have fueled net absorption throughout the office
market.  Office demand growth surged in 

                                          3
<PAGE>

1996 and 1997, causing calculated net absorption in Manhattan for the overall
market to surpass 7.1 million square feet in 1996 and 9.5 million square feet in
1997.  Net absorption of Class B space accelerated during 1997, but because the
Class A market has been so strong, Class B space represents a smaller proportion
of the total than it did during 1996 (see Table 12 on page 20).

Forecasted Demand Analysis

Forecasted net absorption is based on the number of office occupying  jobs
created.  As Table 14 shows, FIRE sector employment growth picked up in 1997 and
into 1998.  Mergers continue in the banking industry, but although the banking
industry remains an important source of demand for office space, demand has
diversified among a wider base of tenants.  For example, other employment
sectors, whose employees typically do not occupy office space, are more likely
to occupy office space in New York.  Manufacturing, textile and communications
companies in New York frequently have a management presence in the city as
opposed to physical operations.  As a result, RCG conservatively estimates that
10% of private sector jobs, excluding FIRE and services, will occupy office
space.  Assuming each new employee occupies about 175 to 200 square feet, an
average of 4.9 million square feet on net will be absorbed annually during the
five years between 1998 and 2002.  From 1991 through the first quarter of 1998,
just over 30% of the calculated net absorption in Manhattan has occurred in
Class B space.  ASSUMING THAT THIS TREND WILL CONTINUE THROUGH 2002, NET
ABSORPTION WILL BE SUFFICIENT TO CAUSE THE OVERALL CLASS B VACANCY RATE TO FALL
TO 8.7% IN 2002 AND RENT GROWTH TO ACCELERATE TO ABOUT 5.1% PER YEAR.

Table 14
(Table regarding New York MSA Office Employment Growth from 1994 through the
forecast for 2002)

Current and Forecasted Supply Analysis

Improvement in the Manhattan office market is a function of both supply and
demand growth.  Virtually no new construction was completed in Manhattan from
1993 through 1997.  Several factors have limited new construction, including the
lack of available sites, the long lead time for new development, and current
market rents that are well below those needed to justify new construction.  The
only major project underway is the Durst Organizations 1.5 million square-foot
Four Times Square office project that is scheduled for completion in 1999.  The
developer received tax incentives to make this project economically feasible. 
Limited build-to-suit construction is also occurring for tenants with specific
needs.  For example, LVMH, the parent of Louis Vuitton, recently completed a
23-story, 103,000 square-foot office building at 17 to 21 East 57th Street
between Fifth and Madison Avenues.  The building contains Louis Vuitton's
flagship store on its ground floor.  In addition, the German Mission to the
United Nations is building a 23-story, 112,000 square-foot headquarters at 871
United Nations Plaza that will be completed in mid 1998.  In downtown, the only
new construction is a 500,000 square-foot build-to-suit recently completed for
the New York Mercantile Exchange in Battery Park City. 

During the past nine months, several other major buildings have been announced
for Midtown.  In August of 1997, Bear Stearns announced plans for an 850,000
square-foot new global headquarters to be built at 383 Madison Avenue by
Sterling Hines and Fred Wilson, and in October of 1997, Reuters American
Holdings announced that it will lease about 500,000 square feet of an 855,000

square-foot building to be constructed by the Rudin Organization at Three Times
Square.  In March of 1998, a consortium of Boston Properties and the Blackstone
Group paid about $180 per buildable square foot to Prudential for the two
remaining sites in Times Square.  The developers plan to construct two towers of
up to one million square feet each.  Over the longer term, the New York
Metropolitan Transportation Authority is considering mixed-use proposals for the
New York Coliseum Site, several of which include office components of up to 1.2
million square feet.

In addition to this announced construction, RCG believes that as rents rise,
owners will upgrade existing buildings throughout the market.  A number of major
renovations have already been announced.  In Downtown, plans have been announced
for the $100 million renovation of the 1.6 million square-foot building at Two
Broadway and the $60 million renovation of the one million square-foot 60 Broad
Street. Thus, for the five years through 2002, we have factored in an average of
not quite 1.2 million square feet annually in building upgrades throughout the
market.  

None of tese recently announced projects will be completed until 2001, which is
about the time that Class A rents in Midtown will rise to the point that new
construction is justified.  As Table 15 shows, assuming development costs of
approximately $366 per square foot, an expected return of 10%, and no tax
incentives for development, an effective rent of almost $56 is needed to make
construction economically viable.  Even with the addition of this new
construction, because of the size of the market, the new supply will have
limited overall impact on the market.

Rent Analysis

Compared to other major world business centers, office rents in Manhattan are
relatively inexpensive, making the area attractive to foreign companies.  A July
1997 world survey of office occupancy costs by Richard Ellis Company ranked
Midtown Manhattan 13th and Downtown Manhattan 31st among major business centers
around the world.  Midtown Manhattan was less expensive than Bombay, Hong Kong,
Tokyo, London, Moscow, New Delhi, Singapore, Beijing, Shanghai and Paris. 

Rent growth is inversely related to the vacancy rate.  When market conditions
tighten and the market vacancy rate falls below the optimal vacancy rate, rent
growth accelerates.  The optimal vacancy rate is the vacancy rate at which
neither excess supply or demand exists, and it is determined by examining the
historical relationship between vacancy rates and rent growth.  The combined
Midtown and Midtown South Manhattan Class B office vacancy rate was at its
highest in 1992, during which time average asking rents fell the most (see
Figure 16).  Since 1992, the Class B office vacancy rate has decreased, and as
the actual vacancy rate has approached the optimal vacancy rate, average asking
rents stabilized and began to rise again in 1995.  

To forecast rent growth, we use a stock-adjustment disequilibrium model in which
we assume that future rent growth will be a function of inflation plus a
coefficient times the difference between the optimal vacancy rate and the market
vacancy rate.  Based on our forecasted vacancy rates, we believe that, by 2002,
the overall Class B vacancy rate will fall to 8.7% which will cause average
asking rents to increase 5.1% during that year (see Table 16).  Class B average
asking rent growth in the 

                                          5

combined Midtown and Midtown South areas will be 5.9% in 2002, while Downtown
rent growth is forecasted to be 4.2% in 2002.

FORECASTED OFFICE MARKET TRENDS

The growth in demand for office space in Midtown Manhattan will be moderately
strong over the next five years.  Employment growth in the key office-consuming
sectors such as finance, securities, legal services, and accounting accelerated
through 1997, but is expected to slow gradually through 2000 before increasing
again in 2001 and 2001.  When combined with growth in other office occupying 
sectors, an average of 28,200 office space-consuming jobs will be created
annually in New York City between 1998 and 2002.  Assuming a coefficient of
space used per office employee of 175 to 200 square feet, that just over 30% of
the space absorbed is Class B space, and that about half of the Class B space is
in Midtown with another fourth in each Midtown South and Downtown, the
forecasted net absorption for Class B space would be about 1.7 million square
feet per year.

While demand for office space in Midtown will be strong, with the exception of
some building renovations and upgrades, no significant new construction is
expected until the Durst project is completed in 1999.  As a result, we expect
the Class B vacancy rate to fall to 7.0% in the combined Midtown and Midtown
South areas, and 14.0% in Downtown by 2002.  Even with an increase in new
construction between 1999 and 2002, the Class A vacancy rate is expected to fall
to 5.8% in the combined Midtown and Midtown South areas, and 8.1% in Downtown by
2002 (see Appendix Tables A.2 to A.5).  As the vacancy rates fall, growth in
Class B average asking rents will accelerate to 7.8% in the combined Midtown and
Midtown South areas and 5.1% in Downtown. 

Based on the economic rents needed to justify new construction calculated in
Table 15, we believe that the potential exists for significant revenue growth in
the Manhattan marketplace as rental and occupancy rates for office properties
recover to levels that would provide a reasonable return on investment to a
developer of a new Class A multi-tenant office building (see Table 17).
