                             SL GREEN REALTY CORP.
                                  COMMON STOCK
                            ------------------------
 
   
    SL Green Realty Corp. (together with its subsidiaries, the "Company") has
been formed for the purpose of continuing the commercial real estate business of
S.L. Green Properties, Inc., and its affiliates ("SL Green"). For more than 17
years, SL Green has acquired and managed Class B office properties in Manhattan.
Upon completion of the Offering, the Company will own or have contracted to
acquire interests in nine Class B office properties encompassing approximately
2.2 million rentable square feet located in midtown Manhattan (the
"Properties"). In addition, the Company will manage 29 office properties
(including the Properties) encompassing approximately 6.4 million rentable
square feet. Interests of SL Green in certain properties deemed inconsistent
with the Company's investment objectives will not be acquired by the Company.
See "The Properties--Assets Not Being Transferred to the Company." The Company
will operate as a fully integrated, self-administered and self-managed real
estate investment trust (a "REIT"). Management expects that the Company will be
the first publicly-traded real estate company to invest primarily in Manhattan
office properties.
    
 
    The Company is selling all of the shares of Common Stock, par value $.01 per
share, of the Company ("Common Stock") offered by this Prospectus. Upon
completion of the Offering, approximately 21% of the equity in the Company will
be beneficially owned by officers and directors of the Company and certain other
affiliated parties, on a fully diluted basis.
 
    There is currently no public market for the Common Stock. The Company
anticipates that the initial public offering price per share will be between
$19.00 and $21.00. See "Underwriting" for a discussion of the factors to be
considered in determining the initial public offering price. The Common Stock
has been approved for listing, subject to official notice of issuance, on the
New York Stock Exchange under the symbol "SLG."
                            ------------------------
    SEE "RISK FACTORS" BEGINNING ON PAGE 13 FOR CERTAIN FACTORS RELEVANT TO AN
INVESTMENT IN THE COMMON STOCK, INCLUDING, AMONG OTHERS:
 
    - Concentration of all of the Company's properties in midtown Manhattan, and
      the dependence of such properties on the conditions of the New York
      metropolitan economy and the midtown Manhattan office market.
 
    - Absence of arm's length negotiations with respect to the Company's
      interests in the Properties and other assets to be contributed by SL Green
      to the Company in connection with its formation and the fact that SL Green
      and certain related persons will receive substantial economic benefits
      (including the issuance to officers, directors and affiliates of the
      Company of equity interests in the Company valued at approximately $54.7
      million, the use of $20 million of Offering proceeds to repay a portion of
      a loan made to a company owned by Stephen L. Green and of $6.4 million of
      Offering proceeds to purchase the interests of third party partners in the
      Properties), resulting in the risk that the consideration to be paid by
      the Company for such assets may exceed the fair market value of such
      assets and other potential conflicts of interest including those related
      to sales and refinancings of Properties.
 
    - The Company's estimated initial annual distributions represent 106% of its
      estimated initial cash available for distribution, resulting in the
      likelihood that the Company will be required to fund distributions from
      working capital or borrowings or reduce such distributions.
 
    - Recent and expected growth requiring the Company to integrate successfully
      new acquisitions.
 
    - Limitations on the Company's ability to sell or reduce the amount of
      mortgage indebtedness on two of the Properties.
 
    - Lehman Brothers Inc. ("Lehman"), the lead managing underwriter of the
      Offering, and certain of its affiliates will receive material benefits
      from the Offering and the formation transactions in addition to
      underwriting discounts and commissions, including payment to Lehman of a
      financial advisory fee equal to 0.75% of the gross proceeds of the
      Offering and the repayment to a Lehman affiliate of an approximately $40
      million loan made prior to the Offering.
 
    - Limitations on the stockholders' ability to change control of the Company,
      including restrictions on ownership of more than 9.0% of the outstanding
      shares of Common Stock.
                            ------------------------
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
    AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
      NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
         SECURITIES COMMISSION PASSED UPON THE ACCURACY OR
            ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION

                                  THE COMPANY
 
   
    The Company has been formed for the purpose of continuing the commercial
real estate business of SL Green. For more than 17 years, SL Green has been
engaged in the business of owning, managing, leasing, acquiring and
repositioning Class B office properties in Manhattan. Upon completion of the
Offering, the Company will own or have contracted to acquire interests in nine
Class B office properties encompassing approximately 2.2 million rentable square
feet located in midtown Manhattan (the "Properties") and will manage 29 office
properties (including the Properties) encompassing approximately 6.4 million
rentable square feet. Of these Properties, interests in six office Properties
encompassing approximately 1.2 million rentable square feet are currently owned
and managed by SL Green (the "Core Portfolio") and interests in three office
Properties encompassing approximately 1.0 million rentable square feet will be
acquired upon completion of the Offering (the "Acquisition Properties"). As of
June 30, 1997, the weighted average occupancy rate of the Core Portfolio was 97%
and of the Acquisition Properties was 89%. Also, upon completion of the
Offering, the Company will own options to acquire an interest in an additional
Class B office property in midtown Manhattan containing approximately 250,000
rentable square feet and an additional Class B office property in downtown
Manhattan containing approximately 800,000 rentable square feet of office space.
See "The Properties--The Option Properties." Interests of SL Green in certain
properties deemed inconsistent with the Company's investment objectives will not
be acquired by the Company. See "The Properties--Assets Not Being Transferred to
the Company." The Company will operate as a fully integrated, self-administered
and self-managed real estate investment trust (a "REIT"). Management expects
that the Company will be the first publicly-traded real estate company to invest
primarily in Manhattan office properties.
    
 
    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
 
                                       1
<PAGE>
   
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.
Tenants that currently occupy space in SL Green owned or managed properties
include Cowles Business Media, Kallir, Philips, Ross Inc., NationsBank, New York
Hospital, Newbridge Communications, Ross Stores and UNICEF.
    
 
    As described herein, current developments in the New York metropolitan
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" below. The Company will seek 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 attributable to 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."
 
    SL Green was founded in 1980 by Stephen L. Green, its Chairman, President
and Chief Executive Officer. Since that time, SL Green has become a full
service, fully integrated real estate company which, upon completion of the
Offering, will have a portfolio of approximately 6.4 million rentable square
feet of Class B office properties under management. Throughout its history, SL
Green has been involved in the acquisition of 31 Class B office properties in
Manhattan containing approximately four million square feet and the management
of 50 Class B office properties in Manhattan containing approximately 10.5
million square feet.
 
    SL Green has offices in midtown and downtown Manhattan and has established a
staff of more than 50 persons, including 40 professionals with experience in all
aspects of commercial real estate. The Company will be led by, in addition to
Stephen L. Green, 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
21% of the equity of the Company, on a fully diluted basis, will be beneficially
owned by officers and directors of the Company and certain other affiliated
parties.
 
                                  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 all of the Properties in midtown Manhattan, 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;
 
    - absence of arm's length negotiations with respect to the Company's
      interests in the Properties and the other assets to be contributed by SL
      Green to the Company in connection with its formation, resulting in the
      risks that the consideration to be paid by the Company for such assets may
      exceed the fair market value of such assets and that the market value of
      the Common Stock may exceed the stockholders' proportionate share of the
      aggregate fair market value of such assets;
 
                                       2
<PAGE>
    - conflicts of interest in connection with the Formation Transactions (as
      defined below), including the fact that officers, directors and affiliates
      of the Company will receive equity interests in the Company and the
      Operating Partnership (as defined below) with a value of approximately
      $54.7 million, based on the assumed initial public offering price;
 
    - conflicts of interest involving officers and directors of the Company in
      business decisions regarding the Company, including conflicts associated
      with sales and refinancings of 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;
 
    - the Company's estimated initial annual distributions represent 106% of its
      estimated initial cash available for distribution, resulting in the
      likelihood that the Company will be required to fund distributions from
      working capital or borrowings or reduce such distributions.
 
    - 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;
 
   
    - 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
      Offering (the "Lock-out Period"), except in certain circumstances (the
      "Lock-out Provisions"), even if any such sale or reduction in mortgage
      indebtedness would be in the best interests of the Company's stockholders,
      which could benefit certain participants in the Formation Transactions
      (including Stephen L. Green, members of his immediate family and
      unaffiliated partners in the Property-owning entities), and the
      possibility that future property acquisitions in which the Company uses
      partnership interests as consideration will include comparable
      limitations;
    
 
    - Lehman and certain affiliates will receive material benefits from the
      Offering and the Formation Transactions in addition to underwriting
      discounts and commissions, including payment to Lehman of a financial
      advisory fee equal to 0.75% of the gross proceeds of the Offering and the
      repayment to a Lehman affiliate of an approximately $40 million loan made
      to the Company prior to the Offering;
 
    - 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 inability to refinance outstanding indebtedness upon maturity or to
      refinance such indebtedness on favorable terms, the risk of rising
      interest rates in connection with variable rate debt and the absence of
      limitations in the Company's organizational documents on the incurrence of
      debt;
 
   
    - immediate and substantial dilution of $7.02 in the net tangible book value
      per share of the shares of Common Stock purchased in the Offering; and

    - 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.
 
                             CONFLICTS OF INTEREST
 
    Following the formation of the Operating Partnership and the completion of
the Offering, there will be conflicts of interest, with respect to certain
transactions, between the holders of Units (including Mr. Green) and the
stockholders of the Company. In particular, the consummation of certain business
combinations, the sale of any properties or a reduction of indebtedness could
have adverse tax consequences to holders of Units which would make such
transactions less desirable to such holders. The Company has adopted certain
policies that are designed to eliminate or minimize certain potential conflicts
of interest. 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 interests of the
Company's stockholders. See "Policies with Respect to Certain
Activities--Conflict of Interest Policies" and "Partnership Agreement."
 
                         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 and continuing
the operating strategies historically practiced by SL Green.
 
    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, a
nationally known real estate consulting company, 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.
 
    - Recent 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 for the foreseeable future 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 11.3% as of June
      30, 1997 from its 1990s high of 17.3% in 1992 and asking rental rates for
      Class B office space in the Midtown Markets increased to $24.44 per square
      foot as of June 30, 1997 from their 1990s low of $21.89 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 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."

GROWTH STRATEGIES
 
    - The Company will seek 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) property repositioning--repositioning acquired
      properties that are underperforming through renovations, active management
      and proactive leasing and (iii) 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 17
      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. In addition, the Company may benefit from the recent abolition of
      the New York State Real Property Transfer Gains Tax and from recent tax
      law developments reducing the transfer tax rates applicable to certain
      REIT acquisition transactions.
 
    - 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 will seek to
      capitalize on management's extensive knowledge of the Class B Manhattan
      marketplace and the needs of the tenants therein by continuing SL Green's
      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 SL Green's 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, SL Green's commitment to tenant service and
      satisfaction is evidenced by the renewal of approximately 80% of the
      expiring rentable square footage (78% of the expiring leases determined by
      number of leases) at the Properties in the Core Portfolio owned and
      managed by SL Green during the period from January 1, 1994 through June
      30, 1997.

THE PORTFOLIO
 
   
    GENERAL.  Upon the completion of the Offering, the Company will own or have
contracted to acquire interests in nine Class B office Properties located in
midtown Manhattan which contain approximately 2.2 million rentable square feet.
Of these Properties, six office properties encompassing approximately 1.2
million rentable square feet are currently owned and managed by SL Green and
three office properties encompassing approximately 1.0 million rentable square
feet will be acquired on or after completion of the Offering. See "Structure and
Formation of the Company--Formation Transactions." Upon completion of the
Offering, the Company will effectively own 100% of the economic interest in all
of the Properties. 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) includes an underground parking garage. In addition
to the foregoing, upon completion of the Offering, the Company will own options
to acquire an interest in an office building containing approximately 250,000
rentable square feet in midtown Manhattan and a property containing
approximately 800,000 rentable square feet of office space in downtown
Manhattan. See "The Properties--The Option Properties."
    
 
    The following table sets forth certain information with respect to each of
the Properties as of June 30, 1997:

- ------------------------
 
(1) As used throughout this Prospectus, Annualized Rent represents the monthly
    contractual rent under existing leases as of June 30, 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 June 30, 1997 for the 12 months ending
    June 30, 1998 are approximately $815,000.
 
(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 SL Green, the remaining lease
    payments under the lease (excluding "free rent" and 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 SL Green and for leases at the
    Acquisition Properties, all lease payments under the lease (excluding "free
    rent" and 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),
    adjusted for tenant improvement costs and leasing commissions, if any, paid
    or payable by SL Green 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) 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).
 
(5) SL Green first acquired an interest in the Bar Building in October 1996. SL
    Green has commenced an aggressive leasing program at the Property and as of
    July 15, 1997, approximately 93% of the rentable square feet in the Property
    was leased. The Bar Building is comprised of two buildings, 36 West 44th

                     STRUCTURE AND FORMATION OF THE COMPANY
STRUCTURE OF THE COMPANY
   
    The Company will issue the Common Stock offered hereby and will be the sole
general partner of SL Green Operating Partnership, L.P., a Delaware limited
partnership (the "Operating Partnership") and issuer of the Units. The Company
will conduct substantially all of its business, and will hold all of its
interests in the Properties, through the Operating Partnership. As the sole
general partner of the Operating Partnership, the Company will have exclusive
power to manage and conduct the business of the Operating Partnership, subject
to certain exceptions (including the Lock-out Provisions). See "Partnership
Agreement." The Units may be exchanged for cash or, at the option of the
Company, shares of Common Stock on a one-for-one basis generally commencing two
years after completion of the Offering. See "Partnership Agreement--Transfers of
Interests--Redemption of Units." The Operating Partnership will receive a
contribution of its interests in the Core Portfolio as well as 95% of the
economic interest in S.L. Green Management Corp. (the "Management Corporation"),
S.L. Green Leasing, Inc. (formerly S.L. Green Realty, Inc.) (the "Leasing
Corporation") and Emerald City Construction Corp. (the "Construction
Corporation" and, together with the Management Corporation and the Leasing
Corporation, the "Service Corporations") from the Property-owning entities, the
partners or members of such entities and the holders of interests in the Service
Corporations. See "--Formation Transactions."
    
    The following diagram depicts the ownership structure of the Company upon
completion of the Offering and the Formation Transactions (as defined below):

FORMATION TRANSACTIONS
 
    Certain transactions have been consummated or will be consummated
concurrently with the completion of the Offering. These transactions (the
"Formation Transactions") include the following:
 
   
    - 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"), an affiliate of Lehman Brothers
      Inc., entered into a credit agreement with SL Green pursuant to which LBHI
      agreed to loan to a company owned by Stephen L. Green up to $46 million
      (the "LBHI Loan") to acquire interests in the Core Portfolio and the
      Acquisition Properties, to fund property related operating expenses, to
      fund organizational expenses of the Company and to purchase short-term
      United States Treasury instruments ("Treasury Securities"). The LBHI Loan
      is secured by partnership interests in certain Property-owning entities
      and the Treasury Securities.
 
   
    - The Company will sell 10,100,000 shares of Common Stock in the Offering
      and will contribute the net proceeds therefrom to the Operating
      Partnership in exchange for 10,100,000 Units (which, including the
      issuance of Common Stock to Victor Capital Group, L.P. ("Victor Capital")
      and to the members of SL Green management referred to herein, will
      represent approximately an 81.9% economic interest in the Operating
      Partnership after the Offering).
    
 
   
    - The Operating Partnership will receive a contribution of its interests in
      the Core Portfolio 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 will issue to such
      entities, partners or members and holders 2,383,284 Units (having an
      aggregate value of approximately $47.7 million, based on the assumed
      initial offering 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 will be transferred to SL Green Management LLC (the
      "Management LLC" and, together with the Management Corporation, the
      "Management Entities"), a limited liability company which will be a wholly
      owned subsidiary of the Company.
 
   
    - The Operating Partnership will be granted (i) an option from Green 17
      Battery LLC, a newly-formed limited liability company owned by Stephen L.
      Green ("17 Battery LLC"), to acquire its interest in 17 Battery Place, a
      property containing approximately 800,000 rentable square feet of office
      space in downtown Manhattan for a purchase price of approximately $59
      million in cash and (ii) an option from Green 110E42 Realty LLC, a
      newly-formed limited liability company owned by Mr. Green ("110 Realty
      LLC"), to acquire its interest in 110 East 42nd Street, an office building
      containing approximately 250,000 rentable square feet in midtown Manhattan
      (together with 17 Battery Place, the "Option Properties") for a purchase
      price of approximately $30 million in cash. See "The Properties--The
      Option Properties."
    
 
    - The Operating Partnership will acquire interests in the Acquisition
      Properties for an aggregate purchase price of 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 will use approximately $82.3 million of net
      proceeds from the Offering to repay mortgage debt encumbering the Core
      Portfolio and the LBHI Loan (including approximately $9.4 million in
      proceeds drawn under the LBHI Loan to fund purchase of the Acquisition
      Properties).
 
                                       8
<PAGE>
   
    - The Company will issue 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.
    
 
    No independent third-party appraisals, valuations or fairness opinions have
been obtained by the Company in connection with the Formation Transactions.
Accordingly, there can be no assurance that the value of the Units and other
consideration received in the Formation Transactions by persons or entities
contributing interests in the Core Portfolio and the Service Corporations to the
Operating Partnership is equivalent to the fair market value of such interests.
 
    Additional information regarding the Formation Transactions is set forth
under "Structure and Formation of the Company--Formation Transactions."
 
BENEFITS TO RELATED PARTIES
 
    Certain affiliates of the Company will realize certain material benefits in
connection with the Formation Transactions and the Offering, including the
following:
 
   
    - Certain continuing investors (including Stephen L. Green, members of his
      immediate family and unaffiliated partners in the Property-owning
      entities) will receive 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 $47.7 million, based on the assumed initial public offering
      price (representing approximately 18.1% of the equity of the Company on a
      fully-diluted basis).
    
 
    - The Operating Partnership will use $20 million to repay a portion of the
      LBHI Loan that was made to Green Realty LLC, a newly-formed limited
      liability company indirectly owned by Stephen L. Green and unaffiliated
      with the Company ("Green Realty LLC") and invested in Treasury Securities
      pledged as collateral therefor (which, upon repayment of the LBHI Loan,
      will be 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 that initially will have a value
      of $11.1 million, based on the assumed initial public offering price.
    
 
   
    - 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) will become officers and/or directors of the
      Company. In addition, each of such persons will enter into employment and
      noncompetition agreements with the Company. See "Management--Employment
      and Noncompetition Agreements." Also, the Company will grant to directors,
      officers and employees of the Company options to purchase an aggregate of
      660,000 shares of Common Stock at the initial public offering price under
      the Company's stock option and incentive plan, subject to certain vesting
      requirements. In addition, pursuant to the terms of their employment
      agreements, Messrs. Nettina and Klein will receive loans to purchase
      Common Stock to be issued under such plan in the principal amount of
      $300,000 and $500,000, respectively. See "Management."
    
 
   
    - The structure of the Formation Transactions will provide the Unit
      recipients (including Stephen L. Green, members of his immediate family
      and unaffiliated partners in the Property-owning entities) the opportunity
      for deferral of the tax consequences of their contribution to the
      Operating Partnership of their interests in the Properties,
      Property-owning entities and Service Corporations.
    
 
    - A to-be-formed limited liability company owned by Stephen L. Green and his
      three sons (the "Service Corporation LLC") will 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 will be 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
    
 
                                       9
<PAGE>
   
      immediate family and unaffiliated partners in the Property-owning
      entities) to defer certain tax consequences associated with the Formation
      Transactions.
    
 
    - Persons or entities receiving Units in the Formation Transactions
      (including entities owned by Stephen L. Green) will have registration
      rights with respect to shares of Common Stock issued in exchange for
      Units.
 
    Additional information concerning benefits to related parties is set forth
under "Structure and Formation of the Company--Benefits to Related Parties."

- ------------------------
 
(1) Includes 679,216 shares of restricted Common Stock to be issued in the
    Formation Transactions.
 
(2) Includes 2,383,284 Units expected to be issued in connection with the
    Formation Transactions that may be exchanged for cash or, at the option of
    the Company, shares of Common Stock on a one-for-one basis generally
    commencing two years after completion of the Offering. Excludes 1,515,000
    shares that are issuable upon exercise of the Underwriters' over-allotment
    option and 660,000 shares reserved for issuance upon the exercise of stock
    options to be granted pursuant to the Company's stock option and incentive
    plan concurrently with the Offering.
 
                                 DISTRIBUTIONS
 
    The Company intends to make regular quarterly distributions to holders of
its Common Stock. The initial distribution, covering a partial quarter
commencing on the date of the closing of the Offering and ending on September
30, 1997, is expected to be $         per share, which represents a pro rata
distribution based upon a full quarterly distribution of $.35 per share and an
annual distribution of $1.40 per share (or an annual distribution rate of
approximately 7.00%, based on an assumed initial public offering price of
$20.00). See "Distributions."
 
    The Company intends initially to distribute annually approximately 106% of
estimated cash available for distribution. The Company's estimate of cash
available for distribution for the twelve months ending June 30, 1998 is based
upon pro forma Funds from Operations (as defined below) for the 12 months ended
June 30, 1997, with certain adjustments as described in "Distributions." The
Company anticipates that approximately 30% (or $.42 per share) of the
distributions intended to be paid by the Company for the 12-month period
following the completion of Offering will represent a return of capital for
Federal income tax purposes and in such event will not be subject to Federal
income tax under current law to the extent such distributions do not exceed a
stockholder's basis in his Common Stock. The Company intends to maintain its
initial distribution rate for the 12-month period following the completion of
the Offering unless actual results of operations, economic conditions or other
factors differ materially from the assumptions used in its estimate.
Distributions by the Company will be determined by the Board of Directors and
will be dependent upon a number of factors, including revenue received from the
Company's properties, the operating expenses of the Company, interest expense,
the ability of tenants at the Company's properties to meet their financial
obligations and unanticipated capital expenditures. The Company believes that
its estimate of cash available for distribution is reasonable; however, no
assurance can be given that the estimate will prove accurate, and actual
distributions may therefore be significantly different from expected
distributions. See "Distributions." The Company does not intend to reduce the
expected distribution per share if the Underwriters' over-allotment option is
exercised.

<PAGE>
                           TAX STATUS OF THE COMPANY
 
    The Company intends to elect to be taxed as a REIT under Sections 856
through 860 of the Internal Revenue Code of 1986, as amended (the "Code"),
commencing with its taxable year ending December 31, 1997, and believes its
organization and proposed method of operation will enable it to meet the
requirements for qualification as a REIT. Based on various assumptions and
factual representations made by the Company regarding the various requirements
for qualification as a REIT, in the opinion of Brown & Wood LLP, counsel for the
Company, 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. The opinion of Brown & Wood LLP is not,
however, binding on the Internal Revenue Service (the "IRS") or any court.
 
    To maintain REIT status, an entity must meet a number of organizational and
operational requirements. In addition, in order to maintain its qualification as
a REIT under the Code, the Company generally will be required each year to
distribute at least 95% of its net taxable income (excluding any net capital
gain). See "Material Federal Income Tax Consequences--Taxation of the
Company--Annual Distribution Requirements." As a REIT, the Company generally
will not be subject to Federal income tax on 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--Taxation of the Company--Failure to
Qualify" and "Risk Factors--Failure to Qualify as a REIT Would Cause the Company
to be Taxed as a Corporation." 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.
                     SUMMARY SELECTED FINANCIAL INFORMATION
 
    The following table sets forth summary selected financial and operating
information on a pro forma basis for the Company, and on a historical combined
basis for the SL Green Predecessor (as defined below), and should be read in
conjunction with all of the financial statements and notes thereto included in
this Prospectus. The combined historical balance sheet information as of
December 31, 1996 and 1995 and statements of income for the years ended December
31, 1996, 1995, and 1994 of the SL Green Predecessor have been derived from the
historical combined financial statements audited by Ernst & Young LLP,
independent auditors, whose report with respect thereto is included elsewhere in
this Prospectus. The operating data for the six months ended June 30, 1997 and
1996 and the years ended December 31, 1993 and 1992 have been derived from the
unaudited combined financial statements of the SL Green Predecessor. In the
opinion of management of the SL Green Predecessor, the operating data for the
six months ended June 30, 1997 and 1996 and the years ended December 31, 1993
and 1992 include all adjustments (consisting only of normal recurring
adjustments) necessary to present fairly the information set forth therein. The
results of operations for the interim periods ended June 30, 1997 and 1996 are
not necessarily indicative of the result to be obtained for the full fiscal
year.
 
    The "SL Green Predecessor" consists of 100% of the net assets and results of
operations of two Properties, 1414 Avenue of the Americas and 70 West 36th
Street, equity interests in four other Properties, 673 First Avenue, 470 Park
Avenue South, 29 West 35th Street and the Bar Building (which interests are
accounted for under the equity method) and 100% of the net assets and results of
operations of the Service Corporations.
 
    The unaudited pro forma financial and operating information for the Company
as of and for the six months ended June 30, 1997 and the year ended December 31,
1996 assumes completion of the Offering and the Formation Transactions as of the
beginning of the periods presented for the operating data and as of the stated
date for the balance sheet data. The pro forma financial information is not
necessarily indicative of what the actual financial position and results of
operations of the Company would have been as of and for the period indicated,
nor does it purport to represent the Company's future financial position and
results of operations.

- ------------------------
 
(1) The White Paper on Funds from Operations approved by the Board of Governors
    of the National Association of Real Estate Investment Trusts ('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 Common Stock involves various risks. Prospective
investors should carefully consider the following information before making a
decision to purchase Common Stock in the Offering.
 
THE COMPANY'S DEPENDENCE ON THE MIDTOWN MARKETS DUE TO LIMITED GEOGRAPHIC
  DIVERSIFICATION COULD ADVERSELY AFFECT THE COMPANY'S FINANCIAL PERFORMANCE
 
    All of the Properties are 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.
 
THERE IS NO ASSURANCE THAT THE COMPANY IS PAYING FAIR MARKET VALUE FOR THE
  PROPERTIES
 
    The amount of consideration in the Company to be received by SL Green and
certain related parties in the Formation Transactions was not determined as a
result of arm's length negotiations with such persons or with purchasers in the
Offering. The amount of consideration to be paid by the Company to acquire
interests in the Properties was determined by SL Green, and SL Green and certain
related persons will receive substantial economic benefits as a result of the
consummation of the Formation Transactions and the Offering. See "Structure and
Formation of the Company--Benefits to Related Parties." No independent
valuations or appraisals of the Properties were obtained by the Company in
connection with the acquisition of property interests in the Formation
Transactions. Accordingly, there can be no assurance that the consideration to
be paid by the Company for these interests represents the fair market value
thereof or that such consideration does not exceed the estimates of value.
 
    The valuation of the Company has not been determined by a valuation of its
assets, but instead has been determined by SL Green and the Underwriters based
upon a capitalization of the Company's pro forma Funds from Operations,
estimated cash available for distribution and potential for growth, and the
other factors discussed under "Underwriting." Prudential Securities Incorporated
will act as "qualified independent underwriter" in connection with the Offering.
See "Underwriting." In determining the estimated initial public offering price,
certain assumptions were made concerning the estimate of revenue to be derived
from the Properties. See "Distributions." This methodology has been used because
management believes that it is appropriate to value the Company as an ongoing
business, rather than with a view to values that could be obtained from a
liquidation of the Company or of individual assets owned by the Company. There
can be no assurance that the price paid by the Company for its interests in the
Properties and for its other assets will not exceed the fair market value of
such assets, and it is possible that the market value of the Common Stock may
exceed stockholders' proportionate share of the aggregate fair market value of
such assets.
 
                                       13
<PAGE>
CONFLICTS OF INTEREST IN THE FORMATION TRANSACTIONS AND THE BUSINESS OF THE
  COMPANY COULD ADVERSELY AFFECT 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, will be holders of 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.
    
 
    THE COMPANY MAY PURSUE LESS VIGOROUS ENFORCEMENT OF TERMS OF CONTRIBUTION
AND OTHER AGREEMENTS BECAUSE OF CONFLICTS OF INTEREST WITH CERTAIN
OFFICERS.  Certain SL Green entities (Hippomenes Associates, LLC, 64-36 Realty
Associates, 673 First Associates, L.P., Green 6th Avenue Asociates, L.P., S.L.
Green Realty, Inc., S.L. Green Properties, Inc. and EBG Midtown South Corp.)
have ownership interests in the Properties and in the other assets to be
acquired by the Company. Following the completion of the Offering and the
Formation Transactions, the Company, under the agreements relating to the
contribution of such interests, will be entitled to indemnification and damages
in the event of breaches of representations or warranties made by such SL Green
entities. In addition, Stephen L. Green, David J. Nettina, Nancy A. Peck, Steven
H. Klein, Benjamin P. Feldman, Gerard Nocera and Louis A. Olsen will enter into
employment and noncompetition agreements with the Company pursuant to which they
will agree, 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 WILL EXIST IN FUTURE DEALINGS WITH AFFILIATES OF THE
COMPANY.  After the completion of the Offering and the Formation Transactions,
two SL Green entities owned by a son of Stephen L. Green (First Quality
Maintenance, L.P. and Classic Security LLC) may provide cleaning and security
services to office properties, including the Company's Properties. These
entities currently provide such services at the 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 obtained over the 17 year operating history of SL Green, that the
terms and conditions of the contracts pursuant to which these services would be
provided would not be less favorable to the Company than those which could have
been obtained from a third party-providing comparable services, such contracts
will not be 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."
    
 
                                       14
<PAGE>
    OUTSIDE INTERESTS OF OFFICERS AND DIRECTORS COULD CONFLICT WITH THE
COMPANY'S INTERESTS.  Certain officers and directors of the Company will
continue to 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. See "The Properties--Assets Not Being Transferred to
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."
 
ESTIMATED INITIAL CASH AVAILABLE FOR DISTRIBUTION WILL NOT BE SUFFICIENT TO MAKE
  DISTRIBUTIONS AT EXPECTED LEVELS
 
    The Company's estimated initial annual distributions represent 106% of the
Company's estimated initial cash available for distribution for the twelve
months ending June 30, 1998. Accordingly, it is expected that the Company
initially will be unable to pay its estimated initial annual distribution of
$1.40 per share to stockholders out of cash available for distribution as
calculated under "Distributions" below. Under such circumstances, the Company
could be required to fund distributions from working capital (expected to
aggregate approximately $6.2 million upon completion of the Offering), draw down
under the Line of Credit, if available, to provide funds for such distribution,
or to reduce the amount of such distribution. In the event the Underwriters'
over-allotment is exercised, pending investment of the proceeds therefrom, the
Company's ability to pay such distribution out of cash available for
distribution may be further adversely affected.
 
THE COMPANY MAY NOT ACHIEVE EXPECTED RETURNS ON RECENTLY ACQUIRED PROPERTIES AND
  PROPERTY ACQUISITIONS
 
    The Company is experiencing a period of rapid growth. The Company's ability
to manage its growth effectively will require it to integrate successfully its
new acquisitions. Including the Acquisition Properties, three of the Properties
have relatively short or no operating history under management by SL Green. SL
Green has had limited control over the operation of these Properties, and such
Properties may have characteristics or deficiencies unknown to the Company
affecting their valuation or revenue potential. No assurance can be given as to
the future operating performance of these Properties under the Company's
management.
 
   
    The Company is currently under contract to acquire three Class B office
properties encompassing approximately 1.0 million rentable square feet. See "The
Properties--Acquisition Properties." In addition, the Company will own options
to purchase interests in two additional Class B office properties containing
approximately 800,000 rentable square feet of office space and approximately
250,000 rentable square feet of office space, respectively. See "The
Properties--The Option Properties." In the future, the Company expects to
acquire additional office properties. As noted 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. See "--Other Risks of Ownership of
Common Stock Could Adversely Affect the Trading Price of the Common Stock--The
Company's dependence on external sources of capital could adversely affect the
Common Stock price" below.
    
 
                                       15
<PAGE>
    To the extent any future growth of the Company is accompanied by the
issuance of additional shares of Common Stock, any such issuance could have the
effect of diluting existing stockholders' interests in the Company.
 
LIMITATIONS ON ABILITY TO SELL OR REDUCE THE MORTGAGE INDEBTEDNESS ON CERTAIN
  PROPERTIES COULD ADVERSELY AFFECT THE VALUE OF THE COMMON STOCK
 
   
    In connection with the solicitation of approval of partners or members in
the various Property-owning entities to transfer their interests to the Company,
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 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 (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 (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.
 
THE MANAGING UNDERWRITER WILL RECEIVE MATERIAL BENEFITS
 
   
    Lehman Brothers Inc. ("Lehman"), the lead managing underwriter of the
Offering, and certain of its affiliates will receive material benefits from the
Offering and the Formation Transactions in addition to underwriting discounts
and commissions. The Company will pay Lehman an advisory fee equal to 0.75% of
the gross proceeds of the Offering (including any exercise of the Underwriters'
overallotment option) for advisory services in connection with the evaluation,
analysis and structuring of the Company's formation as a REIT. Affiliates of
Lehman will be repaid the LBHI Loan in the aggregate principal amount of
approximately $40 million made to certain affiliates of the Company prior to the
Offering and will receive an administrative fee of up to .02% in connection with
a credit facility being arranged for the Company in anticipation of the
establishment of a revolving line of credit being negotiated by the Company and
Lehman. See "Use of Proceeds," "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources,"
"The Properties--Credit Facility" and "Underwriting." Prudential Securities
Incorporated will act as "qualified independent underwriter" in connection with
the Offering. See "Underwriting."
    
 
THE ABILITY OF STOCKHOLDERS TO EFFECT A CHANGE OF CONTROL OF THE COMPANY IS
  LIMITED
 
    STOCK OWNERSHIP LIMIT 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." Although the Board of Directors presently has no
intention of doing so, the Board of Directors could waive these restrictions if
evidence satisfactory to the Board of Directors and the Company's tax counsel
was 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
decided such action would be in the best interests of the Company. 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."
 
                                       17
<PAGE>
    POTENTIAL EFFECTS OF STAGGERED BOARD COULD INHIBIT CHANGES IN CONTROL.  The
Company's Board of Directors will be divided into three classes. 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 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. No
shares of Preferred Stock will be issued or outstanding as of the closing of the
Offering.
 
    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."
 
   
DEPENDENCE ON SMALLER AND GROWTH-ORIENTED BUSINESSES TO RENT CLASS B OFFICE
  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 make expected distributions to
stockholders.
    
 
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 income and ability 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
 
                                       18
<PAGE>
tenants; the expense of periodically renovating, repairing and re-leasing space
(including, without limitation, substantial tenant improvement costs 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 make expected distributions to its stockholders could be
adversely affected.
 
    TENANT DEFAULTS AND BANKRUPTCIES COULD ADVERSELY AFFECT THE COMPANY'S CASH
FLOW.  Substantially all of the Company's income will be derived from rental
income from its properties and, consequently, the Company's distributable cash
flow and ability to make expected 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 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 ability to make
expected distributions to its stockholders could be adversely affected. While SL
Green has 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 will be subject to the risk that upon expiration of leases for space
located in the Properties, the 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 2.3% and 3.4% of the total leased square feet at the Properties expire during
1997 and 1998, 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 impose certain
special restrictions with respect to the sale of certain of the Properties
during the Lock-out Period. 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 ability to make distributions to
stockholders could be adversely affected.
 
                                       19
<PAGE>
    INVESTMENTS IN MORTGAGE LOANS COULD CAUSE EXPENSES WHICH COULD ADVERSELY
AFFECT THE COMPANY'S FINANCIAL CONDITION.  Upon completion of the Formation
Transactions, the Company will acquire a mortgage interest in the Bar Building
and 1372 Broadway, which mortgage interests will provide the Company with
substantially all control over and economic interest derived from such
Properties. See "The Properties--36 West 44th Street (The Bar Building)" and
"--Acquisition Properties--1372 Broadway." 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.
 
    JOINT VENTURE 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 or other entities, acquiring non-controlling interests in or
sharing responsibility for managing the affairs of a property, partnership,
joint venture 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 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 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 or co-venturer would have full control over the partnership or joint
venture. Consequently, actions by such partner 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 or co-venturers. The Company will seek to
maintain sufficient control of such entities to permit it to achieve its
business objectives.
 
    THE EXPIRATION OF NET LEASES COULD ADVERSELY AFFECT THE COMPANY'S FINANCIAL
CONDITION.  As described herein, upon completion of the Offering, with respect
to three of the Properties (35 West 43rd Street (a part of the Bar Building),
673 First Avenue and 1140 Avenue of the Americas), the Company will hold a
long-term leasehold 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 83 years in the case of 35 West 43rd Street, 40 years in the case
of 673 First Avenue and 19 years (with an option to extend for a further 50 year
term) in the case of 1140 Avenue of the Americas. 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 (which will run for the benefit of the Company), 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
lease), then the Company will have 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 June 30, 1997) during the twelve months ended June 30, 1997,
four tenants (Kallir, Philips, Ross Inc., a subsidiary of The Omnicom Group
Ltd., New York
 
                                       20
<PAGE>
Hospital, Gibbs & Cox and Newbridge Communications) each accounted for more than
3% of the Company's pro forma total annualized rental revenues and 12 tenants
collectively accounted for approximately 34.1% of the Company's pro forma total
annualized rental revenues. In addition, New York Hospital occupied 65,000
rentable square feet of additional space pursuant to subleases. 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.
 
    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 SL Green
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 SL Green 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 (defined below) 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 pay expected distributions to stockholders.
 
   
    CREDIT FACILITY REQUIREMENTS COULD ADVERSELY AFFECT THE COMPANY'S ABILITY TO
MAKE EXPECTED DISTRIBUTIONS. Subject to negotiation of mutually satisfactory
covenants and other terms, LBHI has agreed to provide the Company with a $75
million revolving credit facility (the "Credit Facility") that will be used to
facilitate acquisitions and for working capital purposes. Although the Company
expects that the Credit Facility will be established shortly after the
completion of the Offering, there can be no assurance at this time as to whether
the Company will be successful in obtaining the Credit Facility or, if the
Credit Facility is established, the final terms thereof. While none of the
Company's Properties are currently subject to cross-default or
cross-collateralization provisions, there can be no assurance that the Credit
Facility or other future forms of financing will not contain such provisions.
    
 
    It is anticipated that borrowings under the Credit Facility will be secured
by a first mortgage lien on certain Properties in which the Operating
Partnership will acquire interests therein in connection with the Formation
Transactions. If payments required under the Credit Facility cannot be made or
if there should occur other events of default, the lender may seek to foreclose
on those assets securing borrowings under
 
                                       21
<PAGE>
the Credit Facility which could have a material adverse effect on the ability of
the Company to make expected distributions to stockholders and distributions
required by the REIT provisions of the Code. 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. See "The Properties--Credit
Facility."
 
    THE COMPANY'S POLICY OF NO LIMITATION ON DEBT COULD ADVERSELY AFFECT THE
COMPANY'S CASH FLOW.  Upon completion of the Offering and the Formation
Transactions, the debt to market capitalization ratio ("Debt Ratio") of the
Company will be approximately 15.0%. 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. 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.
 
PURCHASERS OF COMMON STOCK IN THE OFFERING WILL EXPERIENCE IMMEDIATE AND
  SUBSTANTIAL
  BOOK VALUE DILUTION
 
   
    As set forth more fully under "Dilution," the pro forma net tangible book
value per share of the assets of the Company after the Offering will be
substantially less than the estimated initial public offering price per share in
the Offering. Accordingly, purchasers of the Common Stock offered hereby will
experience immediate and substantial dilution of $7.02 in the net tangible book
value of the Common Stock from the assumed initial public offering price. See
"Dilution."
    
 
FAILURE TO QUALIFY AS A REIT WOULD CAUSE THE COMPANY TO BE TAXED AS A
  CORPORATION
 
    THE COMPANY WILL BE TAXED AS A CORPORATION IF IT FAILS TO QUALIFY AS A
REIT.  The Company intends to operate so as to qualify as a REIT for Federal
income tax purposes. The Company expects to qualify as a REIT, but no assurance
can be given that it will so qualify or be able to remain so qualified. The
Company has received an opinion of its counsel, Brown & Wood LLP, that, based on
certain assumptions and representations, the Company is organized in conformity
with the requirements for qualification as a REIT under the Code and the
Company's proposed method of operation will enable it to meet the requirements
for qualification and taxation as a REIT. Investors should be aware, however,
that opinions of counsel are not binding on the IRS or any court. The REIT
qualification opinion only represents the view of counsel to the Company based
on counsel's review and analysis of existing law, which includes no controlling
precedent. Furthermore, both the validity of the opinion and the qualification
of the Company as a REIT will depend on the Company's continuing ability to meet
various requirements concerning, among other things, the ownership of its
outstanding stock, the nature of its assets, the sources of its income and the
amount of its distributions to its stockholders. Because the Company has no
history of operating so as to qualify as a REIT, there can be no assurance that
the Company will do so successfully. See "Material Federal Income Tax
Consequences--Taxation of the Company--Failure to Qualify."
 
                                       22
<PAGE>
    If the Company were to fail to qualify as a REIT for any taxable year, the
Company would not be allowed a deduction for distributions to its stockholders
in computing its taxable income and would be subject to Federal income tax
(including any applicable minimum tax) on its taxable income at regular
corporate rates. Unless entitled to relief under certain Code 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. As a result, cash
available for distribution would be reduced for each of the years involved. In
addition, although the Company intends to operate in a manner designed to
qualify as a REIT, it is possible that future economic, market, legal, tax or
other considerations may cause the Board of Directors, with the consent of
stockholders holding at least a majority of all of the outstanding shares of
Common Stock, to revoke the REIT election. Furthermore, no assurance can be
given that new legislation, Treasury Regulations, administrative interpretations
or court decisions will not significantly change the tax laws with respect to
the Company's qualification as a REIT or the Federal income tax consequences of
such qualification. See "Material Federal Income Tax Consequences."
 
    TO QUALIFY AS A REIT THE COMPANY MUST MAINTAIN MINIMUM DISTRIBUTION
REQUIREMENTS.  In order to qualify as a REIT, the Company generally will be
required each year to distribute to its stockholders at least 95% of its net
taxable income (excluding any net capital gain). In addition, the Company may be
subject to income and excise tax if the Company does not meet certain
distribution requirements. See "Material Federal Income Tax
Consequences--Taxation of the Company--Annual Distribution Requirements."
 
    The Company intends to make distributions to its stockholders to comply with
the 95% distribution requirement and to avoid income and excise tax. The
Company's income will consist primarily of its share of the income of the
Operating Partnership, and the cash available for distribution by the Company to
its stockholders will consist of its share of cash distributions from the
Operating Partnership. Differences in timing between (i) the actual receipt of
income and actual payment of deductible expenses, and (ii) the inclusion of such
income and deduction of such expenses in arriving at taxable income of the
Company, could require the Company, through the Operating Partnership, to borrow
funds on a short-term basis to meet the 95% distribution requirement and to
avoid income and excise tax. The requirement to distribute a substantial portion
of the Company's net taxable income could cause the Company to distribute
amounts that otherwise would be spent on future acquisitions, unanticipated
capital expenditures or repayment of debt, which could require the Company to
borrow funds or to sell assets to fund the costs of such items.
 
    OTHER TAX LIABILITIES COULD ADVERSELY AFFECT THE COMPANY'S CASH FLOW.  Even
if the Company qualifies as a REIT, it will be subject to certain Federal, state
and local taxes on its income and property. In particular, the Company will
derive a portion of its operating cash flow from the activities of the Service
Corporations, which will be subject to Federal, state and local income tax. See
"Material Federal Income Tax Consequences--Other Tax Considerations--Service
Corporations."
 
LACK OF OPERATING HISTORY AND INEXPERIENCE OF MANAGEMENT IN OPERATING A REIT
  COULD
  AFFECT REIT QUALIFICATION
 
    The Company has been recently organized and has no operating history. The
Company's Board of Directors and executive officers will have overall
responsibility for management of the Company. Although certain of the Company's
executive officers and directors have extensive experience in the acquisition,
management and financing of office and other real properties, none of the
executive officers or directors has prior experience in operating a business in
accordance with the Code requirements for maintaining qualification as a REIT.
Failure to maintain REIT status would have an adverse effect on the Company's
ability to make anticipated distributions to stockholders. There can be no
assurance that the past experience of management will be appropriate to the
business of the Company.

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 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 378 million rentable
square feet in Manhattan, approximately 173 million rentable square feet is
comprised of Class B office space and 205 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 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 may compete with other property owners that have
greater resources than the Company. In particular, although currently no other
publicly traded REITs have been formed primarily 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 will face
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 will be subject to the risks associated with the management,
leasing and construction businesses that will be conducted by the Service
Corporations, in which the Operating Partnership will hold 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. Each of these developments could adversely
affect the revenues of the Management Corporation, the Leasing Corporation and
the Construction Corporation and could adversely affect the ability of the
Company to make expected distributions to its stockholders.
 
    In order to maintain its qualification as a REIT, the Company will not have
voting control over the Service Corporations. The Service Corporation LLC will
own 100% of the voting common stock (representing 5% of the economic interest)
of each of the Service Corporations. As a result, the Company will 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 will be limited. As a result, the boards of directors or management
of the Service Corporations may implement business policies or decisions that
 
                                       24
<PAGE>
might not have been implemented by persons elected by the Company and that are
adverse to the interests 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 or SL Green, (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 in order to assess
existing environmental conditions. All of the Phase I assessments have been
conducted since 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 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. See "The
Properties--Environmental Matters."
 
OTHER RISKS OF OWNERSHIP OF COMMON STOCK COULD ADVERSELY AFFECT THE TRADING
  PRICE
  OF THE COMMON STOCK
 
    ABSENCE OF PRIOR PUBLIC MARKET FOR COMMON STOCK COULD ADVERSELY AFFECT THE
COMMON STOCK PRICE.  Prior to the completion of the Offering, there has been no
public market for the Common Stock and there can be no assurance that an active
trading market will develop or be sustained or that shares of Common Stock will
be resold at or above the assumed initial public offering price. The initial
public offering price of the Common Stock will be determined by agreement among
the Company and the underwriters and may not be indicative of the market price
for the Common Stock after the completion of the Offering. See "Underwriting."
 
    AVAILABILITY OF SHARES FOR FUTURE SALE COULD ADVERSELY AFFECT THE COMMON
STOCK PRICE.  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. Beginning up to two years after the completion of
the Offering (or less in certain circumstances), holders of Units may be able to
sell shares of Common Stock
 
                                       25
<PAGE>
received upon exercise of their redemption right in the public market pursuant
to registration or available exemptions from registration. 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.
 
    CHANGES IN MARKET CONDITIONS COULD ADVERSELY AFFECT THE COMMON STOCK
PRICE.  As with other publicly traded equity securities, the value of the Common
Stock will depend upon various market conditions, which may change from time to
time. Among the market conditions that may affect the value of the Common Stock
are the following: the extent to which a secondary market develops for the
Common Stock following the completion of the Offering; the extent of
institutional investor interest in the Company; the general reputation of REITs
and the attractiveness of their equity securities in comparison to other equity
securities (including securities issued by other real estate-based companies);
the Company's financial performance; and general stock and bond market
conditions. Although the offering price of the Common Stock will be determined
by the Company in consultation with the underwriters, there can be no assurance
that the Common Stock will not trade below the offering price following the
completion of the offering.
 
    GROWTH POTENTIAL AND CASH DISTRIBUTIONS COULD ADVERSELY AFFECT THE COMMON
STOCK PRICE.  It is generally believed that the market value of the equity
securities of a REIT is based primarily upon the market's perception of the
REIT's growth potential and its current and potential future cash distributions,
whether from operations, sales or refinancings, and is secondarily based upon
the value of the underlying assets. For that reason, shares of Common Stock may
trade at prices that are higher or lower than the net asset value per share of
Common Stock or per Unit. To the extent the Company retains operating cash flow
for investment purposes, working capital reserves or other purposes, these
retained funds, while increasing the value of the Company's underlying assets,
may not correspondingly increase the market price of the Common Stock. The
failure of the Company to meet the market's expectation with regard to future
earnings and cash distributions likely would adversely affect the market price
of the Common Stock. If the market price of the Common Stock declined
significantly, the Company might breach certain covenants with respect to future
debt obligations, which breach might adversely affect the Company's liquidity
and the Company's ability to make future acquisitions.
 
    CHANGES IN MARKET INTEREST RATES COULD ADVERSELY AFFECT THE COMMON STOCK
PRICE.  One of the factors that will influence the price of the Common Stock
will be the dividend yield on the Common Stock (as a percentage of the price of
the Common Stock) relative to market interest rates. Thus, an increase in market
interest rates may lead prospective purchasers of Common Stock to expect a
higher dividend yield, which would adversely affect the market price of the
Common Stock.
 
    UNRELATED EVENTS COULD ADVERSELY AFFECT THE COMMON STOCK PRICE.  As with
other publicly traded equity securities, the value of the Common Stock will
depend 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.
 
    THE COMPANY'S DEPENDENCE ON EXTERNAL SOURCES OF CAPITAL COULD ADVERSELY
AFFECT THE COMMON STOCK PRICE.  In order to qualify as a REIT under the Code,
the Company generally is required each year to distribute at least 95% of its
net taxable income (excluding any net capital gain). See "Material Federal
Income Tax Consequences--Taxation of the Company--Annual Distribution
Requirements." Because of these distribution requirements, it is unlikely that
the Company will be able to fund all future capital needs, including capital
needs in connection with acquisitions, from cash retained from operations. As a
result, to fund future capital needs, the Company likely will have to rely on
third-party sources of capital, which may or
 
                                       26
<PAGE>
may not be available on favorable terms or at all. The Company's access to
third-party sources of capital will depend upon a number of factors, including
the market's perception of the Company's growth potential and its current and
potential future earnings and cash distributions and the market price of the
Common Stock. Moreover, additional equity offerings may result in substantial
dilution of stockholders' interests in the Company, and additional debt
financing may substantially increase the Company's leverage. See "Policies with
Respect to Certain Activities--Financing Policies."
 
    THE OFFICERS, DIRECTORS AND SIGNIFICANT STOCKHOLDERS OF THE COMPANY WILL
HAVE SUBSTANTIAL INFLUENCE.  Upon the completion of the Offering, management of
the Company collectively will beneficially own approximately 21% of the issued
and outstanding shares of Common Stock and Units (which will be exchangeable by
the holders for cash or, at the election of the Company, shares of Common Stock
on a one-for-one basis generally after two years). See "Principal Stockholders."
In addition, Stephen L. Green and Benjamin P. Feldman will serve on the initial
board of directors of the Company. Accordingly, such persons will 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.
 
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. As described herein,
the Company will not acquire certain real estate assets in which Mr. Green will
retain an interest, including interests in various properties in Manhattan
including a substantially vacant showroom building, a loft building, an office
building the equity of which is controlled by the leasehold mortgagee, retail
and other non-office commercial space located in predominantly residential
buildings and a warehouse/distribution center located in Pennsylvania. See "The
Properties--Assets Not Being Transferred to the Company." It is expected that
Mr. Green will not devote a substantial amount of time to the management or
operation of these excluded properties. Prior to the completion of the Offering,
each of the executive officers, including Mr. Green, will enter into an
employment and noncompetition agreement with the Company which will provide,
among other items, that each such person will devote substantially all of his or
her business time to the Company and will except the excluded assets referred to
above from the noncompetition provisions thereof. See "Management--Employment
and Noncompetition Agreements."
    
 
THE SL GREEN PREDECESSOR HAS HAD HISTORICAL ACCOUNTING LOSSES AND HAS A DEFICIT
  IN OWNERS' EQUITY; THE COMPANY MAY EXPERIENCE FUTURE LOSSES
 
   
    The SL Green Predecessor had losses before extraordinary items of
approximately $708,000 and $3.4 million in the years ended December 31, 1996 and
1995, respectively, and had a cumulative deficit in owners' equity of
approximately $6.3 million as of June 30, 1997. These net losses reflect certain
non-cash charges such as depreciation and amortization. These historical results
are not indicative of future results. Nonetheless, there can be no assurance
that the Company will not incur net losses in the future.
    
 
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, will be
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
 
                                       27
<PAGE>
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 initially will carry comprehensive liability, fire, flood,
extended coverage and rental loss (for rental losses extending up to 12 months)
with respect to its 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 its
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.
 
    It is anticipated that new owner's title insurance policies will not be
obtained for two of the Properties in the Core Portfolio (the Bar Building and
1414 Avenue of the Americas) in connection with the Formation Transactions. Each
of these Properties is covered by existing title insurance policies insuring the
interests of the Property-owning entities. Further, each title insurance policy
covering each 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, 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 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 expected distributions 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 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 has been formed for the purpose of continuing the commercial
real estate business of SL Green. For more than 17 years, SL Green has been
engaged in the business of owning, managing, leasing, acquiring and
repositioning Class B office properties in Manhattan. Upon completion of the
Offering, the Company will own or have contracted to acquire interests in nine
Class B office properties encompassing approximately 2.2 million rentable square
feet located in midtown Manhattan (the "Properties") and will manage 29 office
properties (including the Properties) encompassing approximately 6.4 million
rentable square feet. Of these Properties, interests in six office Properties
encompassing approximately 1.2 million rentable square feet are currently owned
and managed by SL Green (the "Core Portfolio") and interests in three office
Properties encompassing approximately 1.0 million rentable square feet will be
acquired upon completion of the Offering (the "Acquisition Properties"). As of
June 30, 1997, the weighted average occupancy rate of the Core Portfolio was 97%
and of the Acquisition Properties was 89%. Also, upon completion of the
Offering, the Company will own options to acquire an additional Class B office
property in midtown Manhattan containing approximately 250,000 rentable square
feet and an additional Class B office property in downtown Manhattan containing
approximately 800,000 rentable square feet of office space. See "The
Properties--The Option Properties". Interests of SL Green in certain properties
deemed inconsistent with the Company's investment objectives will not be
acquired by the Company. See "The Properties--Assets Not Being Transferred to
the Company." The Company will operate as a fully integrated, self-administered
and self-managed REIT. Management expects that the Company will be the first
publicly-traded real estate company to invest primarily in Manhattan office
properties.
    
 
    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. Tenants that currently occupy space in SL Green
owned or managed Properties include Cowles Business Media, Kallir, Philips, Ross
Inc., NationsBank, New York Hospital, Newbridge Communications, Ross Stores and
UNICEF.
    
 
    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
 
                                       29
<PAGE>
Markets declined from 17.3% at year-end 1992 to 11.3% at June 30, 1997) 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 will seek 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."
 
    SL Green was founded in 1980 by Stephen L. Green, its Chairman, President
and Chief Executive Officer. Since that time, SL Green has become a full
service, fully integrated real estate company which, upon completion of the
Offering, will have a portfolio of approximately 6.4 million rentable square
feet of Class B office properties under management. Throughout its history, SL
Green has been involved in the acquisition of 31 Class B office properties in
Manhattan containing approximately four million square feet and the management
of 50 Class B office properties in Manhattan containing approximately 10.5
million square feet.
 
    SL Green has offices in midtown and downtown Manhattan and has established a
staff of more than 50 persons, including 40 professionals with experience in all
aspects of commercial real estate. The Company will be led by, in addition to
Stephen L. Green, 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
21% of the equity of the Company, on a fully diluted basis, will be beneficially
owned by officers and directors of the Company and certain other affiliated
parties.
 
    SL Green consists of six operating divisions, each of which is headed by an
executive team comprised of industry experts with substantial experience in
either the leasing, marketing, asset and property management, construction
management, legal or accounting aspects of the real estate business. The
integration of this expertise allows SL Green to provide high quality, cost
effective leasing and management services essential to enhancing the value of
its office properties.
 
    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
10018-8007 and its telephone number is (212) 594-2700.

                         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 and continuing
the operating strategies historically practiced by SL Green.
 
    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 44,000 jobs per year between 1994 and 1996 for an average annual growth
rate of 1.4%; between May of 1996 and 1997, private sector employment growth was
1.7%, which is the highest 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
10.7% at June 30, 1997 from a 1990s high of 16.8% at year-end 1991. The Class B
segment of the market which tightened to a vacancy rate of 11.3% at June 30,
1997 from its 1990s high of 17.3% at year-end 1992, a 34.7% decline. According
to Rosen Consulting Group, a nationally recognized real estate consulting
company, the outlook in the New York metropolitan area is for healthy private
sector employment growth of approximately 1.4% per annum in 1997 and 1998,
followed by approximately 0.9% growth per annum through 2001, 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
5.7% by 2001, resulting in projected average asking market rents of $31.30 per
square foot, a 28% increase over average asking rents as of June 30, 1997 of
$24.44 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, 1997 the number of such available blocks had declined
to 12. Recent examples of large, traditional Class A tenants relocating into SL
Green owned or managed Class B midtown office space are Newbridge

of K-III Communications moving to 49,000 square feet of space at 673 First
Avenue, Kallir, Philips, Ross Inc., a subsidiary of The Omnicom Group Ltd.
moving to 80,000 square feet at 673 First Avenue, Revere National Corp. moving
to 2,743 square feet at 70 West 36th Street, The Really Useful Company (a
subsidiary of Andrew Lloyd Weber's enterprises) moving to 3,033 square feet at
the Bar Building and Guidepost Associates, the publishing division of The Norman
Vincent Peale Foundation moving to 17,400 square feet at 16 East 34th Street. 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 $24.44 per square foot as of
June 30, 1997 from their 1990s low of $21.89 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
$358 per square foot, which is substantially above the estimated current
acquisition price of Class A space of $225 to $300 per square foot and the
estimated current acquisition price for Class B space of $90 to $200 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.
 
    Further, the Company believes that the recent abolition of the New York
State Real Property Transfer Gains Tax, which effectively reduced the cost of
sales involving commercial properties that have appreciated in value, may create
an increase in the number of properties available for acquisition. Prior to such
abolition, a seller of commercial property in New York was subject to a
substantial New York State gains tax (in addition to income tax). As described
more fully below, the Company may have certain competitive advantages over other
potential acquirors of Class B office space due to its local market expertise,
historical institutional relationships, enhanced access to capital as a public
company and ability to offer tax-advantaged acquisition structures.
 
    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 will seek 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) property repositioning -- repositioning acquired properties that are
underperforming through renovations, active management and proactive leasing and
(iii) integrated leasing and property management.
 
                                       32

PROPERTY ACQUISITIONS
 
    The Company will seek to continue SL Green's ability 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 will evaluate 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 will have the following competitive advantages
over its competitors, primarily private companies and individuals, in acquiring
Class B properties in Manhattan:
 
    LOCAL MARKET EXPERTISE.  Since its inception in 1980, SL Green has developed
into a full service, fully integrated real estate company which, upon completion
of the Offering, will manage approximately six million square feet of Class B
office space in Manhattan. Consequently, management has accumulated 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 SL Green 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 that upon completion of the
Offering, the Company should obtain 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 a
public company, the Company will have 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, upon completion of the Offering, a revolving credit
facility for up to $75 million to finance acquisitions. However, no assurances
can be made as to the availability of any such financing sources.
 
    UNIT ACQUISITIONS.  Upon completion of the Offering, management believes
that the Company will be the first publicly-traded real estate company to focus
primarily on the Manhattan Class B office market. As an "UPREIT", the Company
will have 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.
 
    HISTORICAL INSTITUTIONAL RELATIONSHIPS.  Through its 17 year operating
history, SL Green has established relationships with numerous financial
institutions for which it acts as landlord or as a property manager. In
particular, SL Green's substantial third-party management business affords the
Company access to numerous institutional owners of property that may in the
future seek to divest property holdings. SL Green's retention as a property
manager by such owners has in the past led to opportunities to acquire the
managed property or other properties held by such owner. As an example of the
opportunities such relationships can create, within six weeks of taking over the
management and leasing responsibilities at 36 West 44th Street (The Bar
Building), a 165,000 square foot Class B office property in midtown Manhattan
 
                                       33
<PAGE>
which represented 8.5% of the Annualized Rent at the Properties as of June 30,
1997, SL Green contracted to purchase a mortgage interest encumbering the
property from an insurance company with whom SL Green had prior business
dealings. This mortgage interest is convertible by the Company, at its option,
into fee ownership. The ability of SL Green to assess quickly the current and
potential value and physical condition of this property enabled SL Green to make
a pre-emptive offer to purchase the property. Consequently, the property was
taken off the market, precluding prospective purchasers from engaging in
acquisition discussions with the insurance company.
 
    RECENT TAX LAW DEVELOPMENTS.  Recently, the New York State legislature voted
to abolish the New York State Real Property Transfer Gains Tax, which
effectively reduced the cost of sales involving commercial properties that have
appreciated in value. Prior to such abolition, sellers of commercial properties
located in New York State were subject to a special 10% tax (2.5% in the case of
certain transfers to REITs) on their gains. Further, the Company will have a
competitive tax advantage due to recent tax law amendments affecting REITs.
Under recent amendments to the New York State and New York City transfer tax
laws, transfer tax rates applicable to certain REIT acquisition transactions
were reduced 50% through August 1999 (from 3.025% to 1.5125% in the aggregate).
Consequently, the Company may be able to structure acquisitions that qualify for
these reduced rates and thereby enhance its attractiveness to sellers.
 
    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."
 
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 SL Green 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. SL Green's construction management division
has renovated approximately two million square feet of office space, including
entire building renovations, at an aggregate cost exceeding $100 million. In the
past, SL Green has 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, SL Green has benefited
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
 
                                       34
<PAGE>
regarding the cost of accommodating tenant preferences and the potential rental
revenues achievable from various repositioning options.
 
    Substantially all of the Properties in the Core Portfolio have benefitted
from SL Green's repositioning strategy. Examples of successful implementation of
this strategy within the Core Portfolio include 673 First Avenue (which property
accounted for 22.1% of the aggregate Annualized Rent at the Properties as of
June 30, 1997) and the Bar Building (which property accounted for 8.5% of the
aggregate Annualized Rent at the Properties as of June 30, 1997). At 673 First
Avenue, SL Green 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, SL Green invested approximately $25 million in the Property for
(i) a 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 97% 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). SL Green is
currently pursuing a similar strategy at the Bar Building. This Property also
suffers from deferred maintenance and is underperforming relative to its market
potential. West Forty-Fourth 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 this Property.
Therefore, in order to capitalize on the location of the building, a distinctive
facade will be created to attract the attention of high quality tenants. Also, a
"pre-built" tenant space program has been undertaken as well as public corridor
renovations, all which have resulted in the execution of 12 leases encompassing
24,500 square feet since acquisition.
 
INTEGRATED LEASING AND PROPERTY MANAGEMENT
 
    The Company intends to continue SL Green's strategy of seeking 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 will seek 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, SL Green has created a network of relationships with leasing
professionals who regularly bring tenants to SL Green owned and managed
properties.
 
    An example of SL Green's successful implementation of its proactive leasing
strategy under uniquely adverse conditions is 16 East 34th Street, a property
managed by SL Green. When SL Green was hired by
 
                                       35
<PAGE>
new ownership in September, 1991 as the leasing and managing agent for 16 East
34th Street, a 330,000 square foot Class B midtown Manhattan office property,
the property was only 50% occupied and suffered from a poor image in its
marketplace. The SL Green team developed a cost effective building redevelopment
program and a related marketing program designed to reposition quickly the
property in its marketplace. The implementation of these programs resulted in
over 150,000 square feet of executed leases to high quality tenants within 18
months, bringing occupancy to 90% during a period of rising and historically
high vacancy rates in Manhattan office properties.
 
    The Company believes that SL Green's proactive leasing efforts have
contributed to average occupancy rates at the Properties that are above the
market average. During the period between 1994 and 1996, properties owned by SL
Green for more than one year averaged occupancy rates of 94.3%, which exceeded
the average of 87.2% for Class B Manhattan office space in the Midtown Markets
by 8.1% over the comparable period.
 
    Another key component of the SL Green leasing strategy that will be
continued by the Company 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. SL
Green's commitment to tenant service and satisfaction is evidenced by the
renewal of approximately 80% of the expiring rentable square footage (78% of the
expiring leases determined by number of leases) at the Properties in the Core
Portfolio owned and managed by SL Green during the period from January 1, 1993
through June 30, 1997.
 
    IMPLEMENTATION OF STRATEGIC MANAGEMENT SYSTEMS.  SL Green'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, SL Green develops and implements a management
program designed to provide tenants with the highest level of service while
maintaining the lowest cost to ownership.
 
    An example of SL Green successfully implementing its strategic management
systems is the Bar Building. Upon purchasing a mortgage interest in the
Property, SL Green implemented a strategic property management program which
reduced operating expenses by more than $400,000 per annum. Specifically, the
management professionals at SL Green rebid the cleaning and security contracts,
evaluated the staffing at the property, and determined the associated costs that
could be reduced while improving service. The aggregate contractual operating
expense reduction was in excess of $300,000. Meanwhile, SL Green's in-house
counsel vigorously managed the real estate tax certiorari process which resulted
in an approximately $100,000 real estate tax reduction.
 
    MAXIMIZING TENANT SATISFACTION.  SL Green seeks to provide tenants with a
level of service more typically found in Class A properties. Characteristics of
SL Green office property redevelopments include upgraded or new entrances,
lobbies, elevator cabs/mechanicals, hallways, bathrooms, windows, telecom
systems and tenant spaces. Additionally, SL Green seeks to provide certain
tenant amenities typically associated only with Class A properties. For example,
SL Green 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, SL Green
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 Offering, after deducting the
underwriting discounts and commissions are estimated to be approximately $189.4
million (approximately $217.8 million if the Underwriters' over-allotment option
is exercised in full), based upon the assumed initial public offering price of
$20.00 per share.
 
   
    The net cash proceeds of the Offering will be used by the Company as
follows: (i) approximately $42.7 million to repay mortgage indebtedness
encumbering the Core Portfolio, including approximately $1.9 million in
prepayment penalties and other financing fees and expenses, (ii) approximately
$6.4 million to purchase the direct or indirect interests of certain
participants in the Formation Transactions in the Properties, (iii)
approximately $99.0 million to acquire the Acquisition Properties (including a
$1.6 million escrow account established in connection with the acquisition of 50
West 23rd Street), (iv) approximately $6.1 million to pay certain expenses
incurred in the Formation Transactions for legal, accounting, and real estate
transfer tax expenses, and Offering Expenses, (v) $27.5 million to repay the
LBHI Loan (excluding the following amounts borrowed under the LBHI Loan that
will be repaid with Offering proceeds and are included above: $200,000 to fund
prepayment penalties, $9.4 million to purchase the Acquisition Properties and
$2.5 million to fund Offering expenses), (vi) $1.5 million to fund payment of a
financial advisory fee to Lehman Brothers Inc. and (vii) $6.2 million to fund
capital expenditures and general working capital needs.
    
 
    If the Underwriters' over-allotment option to purchase 1,515,000 additional
shares of Common Stock is exercised in full, the Company expects to use the
additional net proceeds (which will be approximately $28.2 million) to acquire
additional properties and/or for working capital.
 
    Pending application of the net proceeds of the Offering, 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.
 
    The LBHI Loan was incurred within the 12 month period preceding the date of
this Prospectus. Borrowings under the LBHI Loan bear interest at a weighted
average interest rate of 6.8% and have an average remaining term to maturity of
approximately 1.2 years as of June 30, 1997. The proceeds of the LBHI Loan were
used to acquire interests in the Core Portfolio and Acquisition Properties, to
fund property related operating expenses, to fund organizational expenses and to
purchase Treasury Securities. See "Structure and Formation of the
Company--Benefits to Related Parties."
 
    The mortgages and other indebtedness to be repaid upon the completion of the
Offering (excluding the LBHI Loan) had a weighted average interest rate of
approximately 9.2% and an average remaining term to maturity of 11 years as of
June 30, 1997. The following table sets forth the amount of existing mortgage
debt (excluding the LBHI Loan) to be repaid upon completion of the Offering.

    Facility, subject to negotiation of mutually satisfactory covenants and
    other terms. Although the Company expects that the Credit Facility will be
    established shortly after the completion of the Offering, there can be no
    assurance at this time as to whether the Company will be successful in
    obtaining the Credit Facility or, if the Credit Facility is established, the
    terms thereof. See "The Properties--Credit Facility." In anticipation of the
    establishment of the Credit Facility and in order to satisfy all New York
    State tax requirements and mitigate costs to the Company, it is currently
    expected that LBHI will acquire and modify certain of the mortgage
    indebtedness described above and the proceeds from the Offering intended to
    repay such indebtedness will be deposited into an escrow account which will
    generate a return that will service the principal and interest payments on
    such modified indebtedness. Upon the closing of the Credit Facility, these
    mortgage liens may be utilized to secure future borrowings under the Credit
    Facility. In connection with this credit arrangement, LBHI may receive an
    administrative fee of up to .02% of the amount borrowed. See "Underwriting."
    It is anticipated that a similar arrangement may be employed in connection
    with the Acquisition Properties and other future property acquisitions.

                                 DISTRIBUTIONS
 
    Subsequent to the completion of the Offering, the Company intends to make
regular quarterly distributions to the holders of its Common Stock. The initial
distribution, covering a partial quarter commencing on the date of completion of
the Offering and ending on September 30, 1997, is expected to be $    per share,
which represents a pro rata distribution based on a full quarterly distribution
of $.35 per share and an annual distribution of $1.40 per share (or an annual
distribution rate of approximately 7.00%, based on an assumed initial public
offering price of $20.00). The Company does not intend to reduce the expected
distribution per share if the Underwriters' over-allotment option is exercised.

Operations-- Liquidity and Capital Resources" included elsewhere in this
Prospectus.
 
    The Company intends initially to distribute annually approximately 106% of
estimated Cash Available for Distribution. The estimate of Cash Available for
Distribution for the 12 months ending June 30, 1998 is based upon pro forma
Funds from Operations for the 12 months ended June 30, 1997, adjusted for (i)
certain known events and/or contractual commitments that either have occurred or
will occur subsequent to June 30, 1997 or during the 12 months ended June 30,
1997, but were not effective for the full 12 months, and (ii) for certain
non-GAAP adjustments consisting of (A) revisions to historical rent estimates
from a GAAP basis to amounts currently being paid or due from tenants, (B) pro
forma amortization of financing costs, and (C) an estimate of amounts
anticipated for recurring capitalized tenant improvements, leasing commissions
and capital expenditures. No effect was given to any changes in working capital
resulting from changes in current assets and current liabilities (which changes
are not anticipated to be material) or the amount of cash estimated to be used
for (i) investing activities for acquisition, development, tenant improvement
and leasing costs and (ii) financing activities (other than scheduled mortgage
loan principal payments on existing mortgage indebtedness). The estimate of Cash
Available for Distribution is being made solely for the purpose of setting the
initial distribution and is not intended to be a projection or forecast of the
Company's results of operations or its liquidity, nor is the methodology upon
which such adjustments were made necessarily intended to be a basis for
determining future distributions. Future distributions by the Company will be at
the discretion of the Board of Directors. There can be no assurance that any
distributions will be made or that the estimated level of distributions will be
maintained by the Company.
 
    The Company anticipates that its distributions will exceed earnings and
profits for Federal income tax reporting purposes due to non-cash expenses,
primarily depreciation and amortization, to be incurred by the Company.
Therefore, it is expected that approximately 30% (or $.42 per share) of the
distributions anticipated to be paid by the Company for the 12-month period
following the completion of the Offering will represent a return of capital for
Federal income tax purposes and in such event will not be subject to Federal
income tax under current law to the extent such distributions do not exceed a
stockholder's basis in his Common Stock. The nontaxable distributions will
reduce the stockholder's tax basis in the Common Stock and, therefore, the gain
(or loss) recognized on the sale of such Common Stock or upon liquidation of the
Company will be increased (or decreased) accordingly. The percentage of
stockholder distributions that represents a nontaxable return of capital may
vary substantially from year to year.
 
    The Code generally requires that a REIT distribute annually at least 95% of
its net taxable income (excluding any net capital gain). See "Material Federal
Income Tax Consequences--Taxation of the Company--Annual Distribution
Requirements." The estimated Cash Available for Distribution is anticipated to
be in excess of the annual distribution requirements applicable to REITs under
the Code. 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. For a discussion of the tax treatment of
distributions to holders of Common Stock, see "Material Federal Income Tax
Consequences--Taxation of Stockholders."

    The Company believes that its estimate of Cash Available for Distribution
constitutes a reasonable basis for setting the initial distribution, and the
Company intends to maintain its initial distribution rate for the 12-month
period following the completion of the Offering unless actual results of
operations, economic conditions or other factors differ materially from the
assumptions used in its estimate. The Company's actual results of operations
will be affected by a number of factors, including the revenue received from its
properties, the operating expenses of the Company, interest expense, the ability
of tenants of the Company's properties to meet their financial obligations and
unanticipated capital expenditures. Variations in the net proceeds from the
Offering as a result of a change in the initial public offering price or the
exercise of the Underwriters' over-allotment option may affect Cash Available
for Distribution, the payout ratio based on Cash Available for Distribution and
available reserves. No assurance can be given that the Company's estimate will
prove accurate. Actual results may vary substantially from the estimate.
 
    The following table describes the calculation of pro forma Funds from
Operations for the 12 months ended June 30, 1997 and the adjustments to pro
forma Funds from Operations for the 12 months ended June 30, 1997 in estimating
initial Cash Available for Distribution for the 12 months ending June 30, 1998:

- ------------------------
 
(1) Pro forma net income is based on total revenue of $60,314, of which $5,394
    is derived from management, leasing, construction and other activities
    relating to properties not owned by the Company.
 
(2) Pro forma real estate depreciation for the year ended December 31, 1996 of
    $6,407 minus pro forma real estate depreciation for the six months ended
    June 30, 1996 of $3,016 plus pro forma real estate depreciation for the six
    months ended June 30, 1997 of $3,326.
 
(3) Pro forma amortization (excluding financing costs) for the year ended
    December 31, 1996 of $425 minus pro forma amortization (excluding financing
    costs) for the six months ended June 30, 1996 of $212 plus pro forma
    amortization (excluding financing costs) for the six months ended June 30,
    1997 of $211.
 
(4) 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."
 
   
(5) Represents the (i) net increases in rental income from (a) new leases and
    renewals that were not in effect for the entire 12-month period ended June
    30, 1997 of $1,537 and (b) new leases and renewals that went into effect
    between July 1, 1997 and July 15, 1997 of $146 and (ii) management income
    from a new property management contract for a property not owned by SL Green
    that was not in effect for the entire 12-month period ended June 30, 1997 of
    $112.
    
 
(6) Assumes no lease renewals or new leases (other than month-to-month leases)
    for leases expiring after June 30, 1997 unless a new or renewal lease has
    been entered into by July 15, 1997. The $604 decrease represents the loss in
    net rental income assuming all leases of space expiring between July 1, 1997
    and June 30, 1998 for which no renewals or new leases have been entered into
    by July 15, 1997 expire in accordance with their terms and space covered by
    such expiring leases is not re-leased; the decrease is partially offset by a
    net increase of $112 of rental income from tenants on month-to-month leases
    which are assumed to continue throughout the period.
 
(7) The non-recurring transactions consist of lease surrender income at 1372
    Broadway and a real estate tax refund at 1140 Avenue of the Americas.
 
(8) The amount represents a reduction in interest expense due to amortization of
    the related mortgages over the 12-month period ending June 30, 1998.
 
(9) Represents (i) the effect of adjusting straight-line rental revenue included
    in pro forma net income from the straight-line accrual basis to amounts
    currently being paid or due from tenants ($3,518), (ii) the effect of
    adjusting straight line rental payments included in pro forma net income
    from the straight-line accrual basis to amounts currently being paid or due
    from the tenant attributable to the capitalized and operating lease at 673
    First Avenue ($1,386) and (iii) the effect of compensation expense relating
    to stock loans ($266). See "Management--Employment and Noncompetition
    Agreements." Total rent abatements for leases in effect as of June 30, 1997
    for the 12 months ending June 30, 1998 are approximately $815.

(10) Pro forma amortization of financing costs for the year ended December 31,
    1996 of $149 minus pro forma amortization of financing costs for the six
    months ended June 30, 1996 of $83 plus pro forma amortization of financing
    costs for the six months ended June 30, 1997 of $93. Financing costs for
    periods are based on principal mortgage indebtedness outstanding of $46,700.
    See "The Properties--Mortgage Indebtedness."
 
(11) Pro forma non-real estate depreciation and amortization for the year ended
    December 31, 1996 of $92 minus pro forma non-real estate depreciation for
    the six months ended June 30, 1996 of $46 plus pro forma non-real estate
    depreciation and amortization for the six months ended June 30, 1997 of $47.
 
(12) Reflects recurring tenant improvements and leasing commissions anticipated
    for the 12 months ending June 30, 1998 which have been calculated by
    multiplying (i) the weighted average tenant improvements and leasing
    commissions expenditures for renewed and retenanted space at the Properties
    incurred during 1994, 1995, 1996 and the six months ended June 30, 1997 of
    $9.63 per square foot (assuming a renewal rate of 75% of expiring square
    footage as compared to the actual weighted average renewal rate of 80%
    during the period from January 1, 1994 through June 30, 1997-- See "The
    Properties--The Portfolio--Historical Tenant Improvements and Leasing
    Commissions"), by (ii) 110,280 (the average annual square feet of leased
    space for which leases expire during the years ending December 31, 1997
    through December 31, 2002). The weighted average annual per square foot cost
    of tenant improvements and leasing commission expenditures is presented

    (i) The historical weighted average renewal rate, based on square
       footage, for the Company from January 1, 1994 through June 30, 1997
       is 80%.
 
   
(13) Estimated recurring capital expenditures have been calculated by
    multiplying (i) $0.41 (the weighted average of capital expenditures per
    square foot for the Core Portfolio during the period January 1, 1994 through
    December 31, 1996) by (ii) 2,219 (the aggregate square footage of the Core
    Portfolio and the Acquisition Properties). See "The Properties--The
    Portfolio-- Historical Capital Expenditures." For the 12 months ending June
    30, 1998, the estimated cost of recurring building improvements and
    equipment upgrades and replacements (excluding costs of tenant improvements)
    at the Properties is approximately $910. For the 12 months ending June 30,
    1998, the estimated cost of non-recurring capital expenditures of the
    Properties is approximately $5.2 million. The Company expects to fund
    non-recurring capital expenditures, tenant improvements and leasing
    commissions from working capital or borrowings. Following completion of the
    Formation Transactions and the Offering, the Company expects to have
    remaining net proceeds of $6.2 million available for capital expenditures
    and working capital purposes.
    
 
(14) Scheduled mortgage loan principal payments for the 12 months ending June
    30, 1998.
 
(15) The Company's share of estimated Cash Available for Distribution and
    estimated initial annual cash distributions to stockholders of the Company
    is based on its approximate 81.9% aggregate partnership interest in the
    Operating Partnership.
 
(16) Based on a total of 10,779,216 shares of Common Stock to be outstanding
    after the Offering (10,100,000 shares to be sold in the Offering, assuming
    no exercise of the Underwriters' over-allotment option, and 679,216
    additional shares to be issued in the Formation Transactions.)
 
(17) Calculated as estimated initial annual cash distributions to stockholders
    of the Company divided by the Company's share of estimated Cash Available
    for Distribution for the 12 months ending June 30, 1998. The payout ratio
    based on estimated adjusted pro forma Funds from Operations is 80.7%.

                                    DILUTION
 
   
    At June 30, 1997, the Company had a deficiency in net tangible book value
attributable to continuing investors of approximately $7.9 million. After giving
effect to (i) the sale of the shares of Common Stock offered hereby (at an
assumed initial public offering price of $20.00 per share) and the receipt by
the Company of approximately $183.7 million in net proceeds from the Offering,
after deducting the Underwriters' discounts and commissions, the financial
advisory fee payable to Lehman and other estimated expenses of the Offering,
(ii) the repayment of approximately $82.3 million of mortgage indebtedness
secured by certain of the Properties and the LBHI Loan, and (iii) the other
Formation Transactions, the pro forma net tangible book value at June 30, 1997
would have been approximately $140 million, or $12.98 per share of Common Stock.
This amount represents an immediate increase in net tangible book value of
$17.17 per share to the continuing investors and an immediate and substantial
dilution in pro forma net tangible book value of $7.02 per share of Common Stock
to new investors. The following table illustrates this dilution:

- ------------------------
 
(1) Deficiency in net tangible book value per share prior to the Offering
    attributable to continuing investors is determined by dividing net tangible
    book value of the Company attributable to continuing investors (based on the
    June 30, 1997 net book value of the tangible assets (consisting of total
    assets less intangible assets consisting of deferred lease fees and loan
    costs and after the Formation Transactions, net of liabilities to be
    assumed) by the sum of the number of shares of Common Stock (i) issued and
    outstanding and (ii) issuable (upon the exchange of all Units to be issued)
    to continuing investors in the Formation Transactions.
 
(2) Based on an assumed initial public offering price of $20.00 per share and
    after deducting Underwriters' discounts and commissions and estimated
    expenses of the Offering and the Formation Transactions.
 
   
(3) Based on total pro forma net tangible book value of $140 million divided by
    the total number of shares of Common Stock outstanding after the completion
    of the Offering (10,779,216 shares), and excluding shares that may be
    issuable upon exercise of stock options. There is no impact on dilution
    attributable to the issuance of Common Stock in exchange for Units to be
    issued to the continuing investors in the Formation Transactions because
    such Units would be exchanged for Common Stock on a one-for-one basis.
    
 
(4) Dilution is determined by subtracting net tangible book value per share of
    Common Stock after the Offering from an assumed initial public offering
    price of $20.00.
 
    The following table summarizes, on a pro forma basis giving effect to the
Offering and the Formation Transactions, the number of shares of Common Stock to
be sold by the Company in the Offering and the number of shares of Common Stock
and Units to be issued to the continuing investors in the Formation
Transactions, the deficiency in the net tangible book value as of June 30, 1997

                         SELECTED FINANCIAL INFORMATION
 
    The following table sets forth summary selected financial and operating
information on a pro forma basis for the Company, and on a historical combined
basis for the SL Green Predecessor (as defined below), and should be read in
conjunction with all of the financial statements and notes thereto included in
this Prospectus. The combined historical balance sheet information as of
December 31, 1996 and 1995 and statements of income for the years ended December
31, 1996, 1995, and 1994 of the SL Green Predecessor have been derived from the
historical combined financial statements audited by Ernst & Young LLP,
independent auditors, whose report with respect thereto is included elsewhere in
this Prospectus. The operating data for the six months ended June 30, 1997 and
1996 and the years ended December 31, 1993 and 1992 have been derived from the
unaudited combined financial statements of the SL Green Predecessor. In the
opinion of management of the SL Green Predecessor, the operating data for the
six months ended June 30, 1997 and 1996 and the years ended December 31, 1993
and 1992 include all adjustments (consisting only of normal recurring
adjustments) necessary to present fairly the information set forth therein. The
results of operations for the interim periods ended June 30, 1997 and 1996 are
not necessarily indicative of the results to be obtained for the full fiscal
year.
 
    Historical operating results may not be comparable to future operating
results. In addition, the Company believes that the book value of the
Properties, which reflects historical costs of such real estate assets less
accumulated depreciation, is not indicative of the fair value of the Properties.
 
    The "SL Green Predecessors" consists of 100% of the net assets and results
of operations of two Properties, 1414 Avenue of the Americas and 70 West 36th
Street, equity interests in four other Properties, 673 First Avenue, 470 Park
Avenue South, 29 West 35th Street and the Bar Building (which interests are
accounted for under the equity method) and 100% of the net assets and results of
operations of the Service Corporations.
 
    The unaudited pro forma financial and operating information for the Company
as of and for the six months ended June 30, 1997 and the year ended December 31,
1996 assumes completion of the Offering and the Formation Transactions as of the
beginning of the periods presented for the operating data and as of the stated
date for the balance sheet data. The pro forma financial information is not
necessarily indicative of what the actual financial position and results of
operations of the Company would have been as of and for the period indicated,
nor does it purport to represent the Company's future financial position and
results of operations.

(1) 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."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The following discussion should be read in conjunction with the Selected
Financial Information, the Historical Combined Financial Statements and the Pro
Forma Combined Balance Sheet and Pro Forma Combined Statements of Income of the
Company contained in this Prospectus.
 
    The Combined Financial Statements of the SL Green Predecessor include 100%
of the net assets and results of operations of two Properties, 1414 Avenue of
the Americas and 70 West 36th Street, equity interests in four other properties,
673 First Avenue, 470 Park Avenue South, 29 West 35th Street and the Bar
Building (which interests are accounted for under the equity method) and 100% of
the net assets and results of operations of the Service Corporations.
 
    Due to the size of the Company's Core Portfolio (six properties), the
inclusion of additional properties during any period can result in significant
increases in total revenue and other financial data over prior periods. For the
foregoing reason, the Company does not believe its year to year and quarter to
quarter financial data are comparable, and that percentage growth may not be
maintained at the current rate.
 
RESULTS OF OPERATIONS
 
    COMPARISON OF SIX MONTHS ENDED JUNE 30, 1997 TO SIX MONTHS ENDED JUNE 30,
1996
 
    Rental revenue increased $1,485,000 or 112.9%, to $2,800,000 from $1,315,000
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. The increase was due primarily to the acquisition of 1414 Avenue of the
Americas during July 1996 which had rental revenue of $1,555,000, partially
offset by a decrease in rental revenue of $70,000 at 70 West 36th Street, due to
a temporary decrease in occupancy and the free rent associated with re-leasing
those spaces.
 
    Escalations and reimbursement revenues increased $171,000, or 60.0%, to
$456,000 from $285,000 for the six months ended June 30, 1997 compared to the
six months ended June 30, 1996. The acquisition of 1414 Avenue of the Americas,
accounted for an increase of $265,000 offset by a decrease of $94,000 at 70 West
36th Street due to reduced porter wage escalations revenue. New leases with more
current base years utilized to calculate the escalations account for the
decreased escalation revenue.
 
   
    Management revenues decreased $97,000, or 9.1% to $966,000 from $1,063,000
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. A building managed for a third party was sold at the end of 1996 and the
management agreement was terminated resulting in this decrease.
    
 
    Leasing commission revenues increased $1,806,000, or 140.9%, to $3,088,000
from $1,282,000 for the six months ended June 30, 1997 compared to the six
months ended June 30, 1996 due to the addition of several buildings under
service contracts and intensified efforts to perform leasing services for
unaffiliated third parties.
 
   
    Construction revenue decreased by $31,000, or 79.5% to $8,000 from $39,000
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. Overall construction revenue remained constant but a larger amount related
to property-owning partnerships in the six months ended June 30, 1997 and was
eliminated pursuant to the equity method of accounting.
    
 
    Other income decreased by $98,000 or 86% to $16,000 from $114,000 for the
six months ended June 30, 1997 compared to the six months ended June 30, 1996
primarily due to a one-time consulting engagement in the six months ended June
30, 1996. The remaining other income consisted of interest income.
 
                                       48

    Share of net loss of uncombined joint ventures decreased $253,000, or 31.0%,
to $564,000 from $817,000 for the six months ended June 30, 1997 compared to the
six months ended June 30, 1996 as follows:

    The decrease in net loss for 673 First Avenue was due primarily to increased
rental revenues and escalation and reimbursement revenues resulting from
increased occupancy and contractual rent increases. The loss was also reduced by
lower operating expenses and a reduction in real estate taxes.
 
   
    The decrease in net loss for 470 Park Avenue South was due primarily to
higher contractual rents and lower operating expenses, offset by reduced porter
wage escalation revenue as a result of new leases with more current base years,
utilized in the calculation of the escalation.
    
 
   
    The decrease in net income of uncombined joint ventures for 29 West 35th
Street was due primarily to reduced porter wage escalation revenue as a result
of new leases with more current base years utilized in the calculation of the
escalation, and by higher operating expenses.
    
 
   
    The increase in net income for the Bar Building was due to the acquisition
of the Property during September 1996.
    
 
   
    Operating expenses increased $395,000, or 32.1%, to $1,625,000 from
$1,230,000 for the six months ended June 30, 1997 compared to the six months
ended June 30, 1996. The increase was comprised primarily of the inclusion of
1414 Avenue of the Americas which was acquired during July 1996 ($506,000),
offset by lower expenses at 70 West 36th Street.
    
 
    Interest expense increased $271,000 or 61.3%, to $713,000 from $442,000 for
the six months ended June 30, 1997 compared to the six months ended June 30,
1996. The inclusion of 1414 Avenue of the Americas accounted for an increase of
$460,000 offset by a decrease of $189,000 for 70 West 36th Street due to
refinancing at a lower interest rate.
 
    Depreciation and amortization increased $193,000, or 47.5%, to $599,000 from
$406,000 for the six months ended June 30, 1997 compared to the six months ended
June 30, 1996. The increase was due primarily to the inclusion of 1414 Avenue of
the Americas.
 
    Real estate taxes increased $250,000, or 107.8% to $482,000 from $232,000
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. The increase was due to the inclusion of $290,000 for 1414 Avenue of the
Americas, offset by a decrease of $40,000 for 70 West 36th St.
 
   
    Marketing, general and administrative expenses decreased $194,000, or 9.6%,
to $1,835,000 from $2,029,000 for the six months ended June 30, 1997 compared to
the six months ended June 30, 1996. The decrease was primarily due to reduced
expenses at the corporations which provide management and leasing services,
offset by increased expenses associated with the increase in leasing commission
revenues.
    
 
   
    As a result of the foregoing, net income increased $2,574,000, or 243.3%, to
$1,516,000 from a loss of $1,058,000 for the six months ended June 30, 1997
compared to the six months ended June 30, 1996.
    
 
    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

    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 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.

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

mortgage financing plus the use of its capital for the acquisition,
redevelopment and renovation of the Properties. The proceeds from the Offering
as well as a new mortgage loan in the amount of $14 million, which will be
secured by 50 West 23rd Street, will be utilized to repay existing mortgage
loans, acquire properties, pay Offering and Formation Transaction expenses and
provide working capital. See "Use of Proceeds" and "The Properties--Mortgage
Indebtedness." The mortgage loans currently secured by the Properties, which
will be consolidated in the financial statements of the Company, will be reduced
from $91.4 million to $32.5 million as a result of the repayment and
cancellation of certain mortgage loans. Total mortgage loans including the new
mortgage loan will amount to $46.5 million as a result of the Formation
Transactions. All mortgage loans encumbering the Core Portfolio have fixed
interest rates ranging from 8.25% to 9.0% and it is anticipated that the new
mortgage loan will also bear interest at a fixed rate. Subsequent to the
Formation Transactions the mortgage loans would represent approximately 15.0% of
the Company's market capitalization based on an estimated total market
capitalization of $309.8 million.

    The Company is currently negotiating with Lehman the terms of the Credit
Facility, which the Company expects to be in place shortly after the completion
of the Offering although there is no assurance that this will be the case. The
Credit Facility will be utilized to facilitate acquisitions and fund associated
renovations, tenant improvements and leasing commissions. After paying down
mortgage debt as well as expenses of the Offering and Formation Transactions,
the Company expects to have working capital of approximately $6.2 million, which
will be used to fund anticipated capital improvements on the Bar Building and
general corporate purposes. The Company estimates that for the 12 months ending
June 30, 1998, it will incur approximately $4.46 million of expenses
attributable to non-incremental revenue generating capital expenditures which
includes $2.18 million for the Acquisition Properties, $1.04 million for the Bar
Building and $1.24 million for the balance of the Core Portfolio.
    
 
   
    The Company expects to make distributions to its stockholders primarily
based on its distributions received from the Operating Partnership or, if
necessary, from working capital or borrowings. 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.
    
 
    Future property acquisitions may require substantial capital leasing of a
property. The Company expects that a portion of such costs will be funded from
draws under the Credit Facility, to the extent the Credit Facility is obtained,
from additional borrowings secured by the target property and from future
issuances of equity and debt. The Company believes that it will have sufficient
capital resources to satisfy its obligations during the 12 month period
following completion of the Offering. Thereafter, the Company expects that
capital needs will be met through a combination of net cash provided by
operations, borrowings and additional equity issuances.
 
CASH FLOWS
 
    COMPARISON OF SIX MONTHS ENDED JUNE 30, 1997 TO SIX MONTHS ENDED JUNE 30,
     1996
 
   
    Net cash provided by operating activities increased $1,085,000 to $1,140,000
from $55,000 for the six months ended June 30, 1997 compared to the six months
ended June 30, 1996. The increase was due primarily to the acquisition of 1414
Avenue of the Americas and an increase in leasing commission income. Net cash
used in investing activities decreased $503,000 to $(145,000) from $(648,000)
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. The decrease was due primarily to a decrease in net cash contributions to
the partnerships that own 29 West 35th Street and 470 Park Avenue South. Net
cash used in financing activities increased $708,000 to $(425,000) from $283,000
for the six months ended June 30, 1997 compared to the six months ended June 30,
1996. The increase was due primarily to the refinancing of the mortgage on 70
West 36th Street, and an increase in distributions of approximately $111,000 to
entities owned by Stephen L. Green and a reduction of contributions from owners.
    
 
    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.

    COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994.
 
   
    Net cash used in operating activities increased by $1,173,000 to a deficit
of $234,000 from a positive cash flow of $939,000 for the year ended December
31, 1995 compared to the year ended December 31, 1994. The increase was due
primarily to operating expense increases related to the corporations which
provide management leasing and construction services and additional marketing,
general and administrative expenses for the corporations which provide
management leasing and construction services. Net cash used in investing
activities decreased $135,000 to $432,000 from $567,000 for the year ended
December 31, 1995 compared to the year ended December 31, 1994. The decrease was
due primarily to reduced investments in building improvements and reduced
contributions to investee partnerships. Cash provided by financing activities
decreased $115,000 to $63,000 from $178,000 due to reduced contributions 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 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 Offering, Funds from
Operations for the six months ended June 30, 1997 and for the year ended
December 31, 1996, respectively, are 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.

                                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
1994, 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 44,000 jobs
per year between 1994 and 1996 for an average annual growth rate of 1.4%;
between May of 1996 and 1997, private sector employment growth was an even
stronger 1.7%, which is the strongest growth rate in more than ten years. In
July of 1996, Inc. magazine named New York City as the "Best Place to Do
Business," stating that urban, compact areas promote interaction among
companies, suppliers and customers.
 
    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 (47) 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 three
years between 1994 and 1996, during which period some 132,000 private sector
jobs were added in the New York metropolitan area (an average of approximately
44,000 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 22,000 jobs between the third quarters of 1995 and 1996.
 
                                       56
<PAGE>
    The single fastest-growing employment sector in the New York metropolitan
economy is the services sector, which grew at a rate of 3.0% during the year
ended in May of 1997. With more than 1.4 million jobs, the services sector
currently represents 37% 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 290,000 jobs as of May 1997, representing 20% of total services
employment. Between 1992 and 1996, growth in business services employment
averaged 4% per year, and between May 1996 and May 1997, business services
employment grew 6.6%. 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. Roughly 1,250 firms in Manhattan belong to
the new media industry, and employment growth in this sector is estimated to be
30% per year through 1998.
 
    The trade sector is the second largest and fastest growing part of the
metropolitan economy, with an employment gain of 6,300 jobs during the 12 months
ended May 31, 1997, representing a 0.9% annual growth rate. Approximately 68% of
the metropolitan area's trade jobs are in the retail sector, where growth was an
even stronger 1.5% 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 169,000 households that have an annual 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 rental rates, after such cities as Tokyo, London, Paris, Hong
Kong and Singapore, while downtown Manhattan ranked 37th.
 
    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 thirty-three additional areas within New York City. In addition,
crime in New York City has declined. Preliminary estimates for
 
                                       57
<PAGE>
1996 show that New York City ranked 159th out of the 198 largest U.S. cities in
terms of total crimes, lower than such cities as Atlanta (1), Miami (8), Phoenix
(42), Milwaukee (83) and Philadelphia (114). According to the New York City
Police Department, New York City's crime rate decreased 16% during 1996, and the
seven felony categories have declined a cumulative 39% since 1993 (a greater
decrease than any other large U.S. city during the last three 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 1.4% per annum, or approximately 33,000 private sector jobs per
annum through 1998, and continue to increase at approximately 0.9% annually
through 2001.
 
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 four
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 1992; and (iii) significant new office development is unlikely 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.
 
                                       58

    SIZE OF MARKET.  The Manhattan office market, with an overall stock of
approximately 378 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

    Within Manhattan, 46% of the office space is classified as Class B space;
almost half of the Class B space is located in midtown, and approximately
one-fourth of the Class B space is located in each of midtown south and
downtown. The following table sets forth the relative sizes of the Class A and
Class B office markets and the rents and vacancy rates as of May 31, 1997
existing in such markets:

    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.

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

    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 17.3% 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 for the
foreseeable future 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. Virtually no new construction of office space in the
Midtown Markets is anticipated in the near term, except one major Class A
development, containing approximately 1.5 million square feet, scheduled to be
completed in 1999, which has substantial grandfathered tax benefits. (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.) 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 $358 per square foot (as estimated by Rosen
 
                                       60
<PAGE>
Consulting Group), a market base rent in excess of $55 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 47% 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 and 1996, reaching 3.0 million, 1.5 million and 1.7 million square
feet, respectively. Net Absorption in the Midtown Markets is forecasted to reach
almost 2.3 million square feet for 1997. An average of 30,200 office
space-consuming jobs are projected to be created annually from 1997 until 2001,
leading to an estimated average annual Net Absorption of Class B office space in
the Midtown Markets of 1.5 million square feet in 1998 and 1999.

</TABLE>
 
    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 10.1% as of June 30, 1997 from its 1990s high of 17.8% in
1991 and the Class B office vacancy rate in the Midtown Markets had fallen to
11.3% from its 1990s high of 17.3% in 1992. As a result of the projected
economic strength and private sector job growth, combined with a lack of
projected new construction through 1998, Rosen Consulting Group projects that
the Class A vacancy rate in the Midtown Markets will fall to 7.6% in 1998 and
further to 5.9% in 2001; similarly, Rosen Consulting Group projects that the
Class B vacancy rate in the Midtown Markets will fall to 8.4% in 1998 and
further to 5.7% in 2001. 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 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 (in excess of $55
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
6% 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."

    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 decrease, which the Company believes should result in
increased rental rates and decreased re-leasing
 
                                       62

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 18.8% as of June 30, 1997 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 $22.42 as of June 30, 1997 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 14.7% by the end of 1998 and to continue to
decline to below 12% by the end of 2001. 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 $23.15 by the end of 1998 and continue
rising to $26.56 by the end of 2001.

THE PORTFOLIO
 
   
    GENERAL.  Upon the completion of the Offering, the Company will own or have
contracted to acquire interests in nine Class B office Properties located in
midtown Manhattan which contain approximately 2.2 million rentable square feet.
Of these Properties, six office properties encompassing 1.2 million rentable
square feet are currently owned and managed by SL Green and three office
properties encompassing approximately 1.0 million rentable square feet will be
acquired on or after completion of the Offering. See "Structure and Formation of
the Company--Formation Transactions." Upon completion of the Offering, the
Company will effectively own 100% of the economic interest in each of the
Properties. 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) includes an underground parking garage. The Company believes that
each of the Properties is adequately covered by property and liability
insurance. In addition, upon completion of the Offering, the Company will own
options to acquire interests in 110 East 42nd Street, an office building
containing approximately 250,000 rentable square feet in midtown Manhattan and
17 Battery Place, a property containing approximately 800,000 rentable square
feet of office space in downtown Manhattan. See "--The Option Properties" below.
    
 
    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 as of June 30, 1997:

(1) As used throughout this Prospectus, Annualized Rent represents the monthly
    contractual rent under existing leases as of June 30, 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 June 30, 1997 for the 12 months ending
    June 30, 1998 are approximately $815,000.
 
(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 SL Green, the remaining lease
    payments under the lease excluding "free rent" and 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 SL Green and for leases at the
    Acquisition Properties, all lease payments under the lease excluding "free
    rent" and 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),
    adjusted for tenant improvement costs and leasing commissions, if any, paid
    or payable by SL Green 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 as a result of the provision for
    future contractual increases in rental payments in the Annual Net Effective
    Rent Per Leased Square Foot data.
    
 
(4) 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).
 
(5) SL Green first acquired an interest in the Bar Building in October 1996. SL
    Green has commenced an aggressive leasing program at the Property and as of
    July 15, 1997, approximately 93% of the rentable square feet in the Property
    was leased. 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).
 
(6) Includes approximately 2,043,000 square feet of rentable office space,
    146,000 square feet of rentable retail space and 30,000 square feet of
    garage space.
 
    HISTORICAL OCCUPANCY.  The Properties in the Core Portfolio historically

    Properties owned by SL Green as of that date.

    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 June 30, 1997, SL Green renewed approximately 78% of the
leases scheduled to expire at the Properties in the Core Portfolio owned and
managed by SL Green during such period, constituting renewal of approximately
80% of the expiring rentable square footage during such period. As a result of
these re-leasing efforts, through December 31, 2002, the average annual rollover
at the Properties is approximately 110,280 square feet, representing an average
annual expiration of 5.3% of the total leased square feet at the Properties 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 June 30,
    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 June 30, 1997
    for the 12 months ending June 30, 1998 are approximately $815,000.
 
(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 June 30, 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
    South, Garment, Park Avenue South/Flatiron and Rockefeller Center
    submarkets), was $24.64 per square foot as of June 30, 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. 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 $22.72.
 
    TENANT DIVERSIFICATION.  The Properties (including the Acquisition
Properties) currently are leased to over 250 tenants which are engaged in a
variety of businesses, including publishing, health services, retailing and
banking. The following table sets forth information regarding the leases with
respect to the 20

    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 June 30,
1997, SL Green renewed approximately 78% of the leases scheduled to expire at
the Properties in the Core Portfolio owned and managed by SL Green during such
period, constituting renewal of approximately 80% of the expiring rentable
square footage in the Core Portfolio during such period. The following table
sets forth certain historical information regarding tenants at the Properties in
the Core Portfolio 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 June 30, 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 an occupancy rate throughout
    such period equal to 94% (the occupancy rate at the Properties as of June
    30, 1997), such weighted average per square foot amount would be $9.63.
 
    HISTORICAL CAPITAL EXPENDITURES.  Each property within the Core Portfolio,
except for the Bar Building, has been substantially renovated. Within the next
18 months the Company anticipates spending $5.3 million in capital improvements
at the Properties, of which approximately $1.1 million is designated for the Bar
Building, an interest in which was first purchased by SL Green in October 1996,
and approximately $3.0 million is designated for the Acquisition Properties. See
"--36 West 44th Street (The Bar Building)" and "--Acquisition Properties" below.
These costs are expected to be paid from remaining net proceeds from the
Offering after completion of the Formation Transactions (estimated to be $6.2
million) and/or from operating cash flows. See "Use of Proceeds."
 
    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 SL Green in 1989 and
1990. SL Green acquired 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 in 1988. Upon completion of the Formation Transactions,
such leasehold interests will be transferred to the Company. See "Risk
Factors--The Company's Performance and Value are Subject to Risks Associated
with the Real Estate Industry--The expiration of net leases could adversely
affect the Company's financial condition."
    
 
    At 673 First Avenue, SL Green 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, SL Green 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 $26.85 per square foot as of June
    30, 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 $22,360,268 as of June 30,
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
$10.072 per $100 of assessed value. The total annual tax for 673 First Avenue at
this rate for the 1997-98 tax year is $1,225,561 (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. SL
Green acquired a 100% fee simple interest in the Property in 1986. Upon
completion of the Formation Transactions, this fee simple interest will be
transferred to the Company. 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 June 30, 1997, 99% of the rentable square footage in 470 Park Avenue
South was leased (including space for leases that were executed as of June 30,
1997). The office space was 99% leased and the retail space was 100% leased. The

(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 $22.38 per square foot as of June 30, 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
SL Green 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. Over the next 18 months, the Company anticipates
replacing the sidewalk in front of the building, upgrading the elevators,
completing a modest facade restoration and scraping and painting the windows, at
an estimated aggregate cost of $337,000.
 
    The aggregate undepreciated tax basis of depreciable real property at 470
Park Avenue South for Federal income tax purposes was $15,006,453 as of June 30,
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
$10.072 per $100 of assessed value. The total annual tax for 470 Park Avenue
South at this rate for the 1997-98 tax year is $648,133 (at an assessed value of
$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 is scheduled for
1997/1998. 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. A limited liability company owned by SL
Green and an unaffiliated real estate fund (the "Bar Building Joint Venture")
acquired non-performing mortgage indebtedness encumbering the Property from an
institutional lender in October 1996 with the intent of obtaining a 100%
economic interest in such Property. Pursuant to a subsequent agreement with the
mortgagor, the Bar Building Joint Venture obtained the right to foreclose on the
Bar Building no earlier than September 30, 1998. Upon recording of the
conveyancing instruments, the Bar Building Joint Venture is required to pay to
the mortgagor and/or its affiliates the sum of $350,000, and to pay the New York
City and New York State Real Property Transfer Gains Taxes imposed upon
recording of the conveyancing instruments. Upon completion of the Formation
Transactions, the Company will acquire all of the mortgage indebtedness
encumbering the Property (representing effectively a 100% economic interest
therein) as well as such right of foreclosure. Upon exercising such right of
foreclosure, the Company would obtain 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 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 SL Green 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, SL Green has implemented an aggressive leasing and
marketing campaign in conjunction with a strategic property-wide renovation
program. The Company is planning to spend $1.1 million over the next 18 months
on this upgrade and renovation program at the Property, which expense will be
funded out of the net proceeds of the Offering. Some of this work includes roof
repair, facade restoration and steam cleaning, window upgrade, entrance and
lobby upgrade, sidewalk replacement and public corridor renovations. As of July
15, 1997, approximately 14,000 square feet of space at the Property was vacant
and approximately 64% of the expiring leases were renewed.
 
    As of June 30, 1997, approximately 89% of the rentable square footage in The
Bar Building was leased. The office space was 89% leased and the retail space
was 89% leased. As noted above, SL Green has commenced an aggressive leasing
program at the Property and as of July 15, 1997, approximately 93%
 
                                       75

(1) Information is as of June 30, 1997.
 
   
    As of June 30, 1997, the Bar Building was leased to 58 tenants operating in
various businesses, including legal, not-for-profit and the theater, one of whom
occupied 10% or more of the rentable square footage at the Property. A
professional organization for lawyers occupied approximately 16,777 square feet
(approximately 10.2% of the Property) under two leases expiring on September 30,
1999 that provide for an aggregate annualized base rent as of June 30, 1997 of
approximately $403,000 (approximately $24.00 per square foot). 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
The Bar Building with respect to leases executed as of June 30, 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 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 $23.32 per square foot as of June 30,
    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 and a
renovation program is scheduled for 1997/1998. The program will include new
windows, lobby and entrance as well as steam cleaning of the facade, at an
estimated aggregate cost of $660,000. SL Green acquired a 100% fee simple
interest in the Property in 1996. Upon completion of the Formation Transactions,
such fee simple interest will be transferred to the Company. 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 June 30, 1997, approximately 98% of the rentable square footage in
1414 Avenue of the Americas was leased (including space for leases that were
executed as of June 30, 1997). The office space was 98% leased and the retail
space was 100% leased. The following table sets forth certain information with

(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 $27.38 per square foot as of June 30, 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 $27.96.
    
 
(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.
 
    The aggregate undepreciated tax basis of depreciable real property at 1414
Avenue of the Americas for Federal income tax purposes was $11,830,680 as of
June 30, 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
$10.072 per $100 of assessed value. The total annual tax for 1414 Avenue of the
Americas at this rate for the 1997-98 tax year is $484,967 (at an assessed value
of $4,815,000).
 
29 WEST 35TH STREET
 
    29 West 35th Street is a 12-story building located on the north side of West
35th Street between Fifth Avenue and Sixth Avenue in the Garment submarket of
the Manhattan office market. The building, situated between Grand Central
Terminal and Penn Station, was completed in 1911 and substantially renovated in
1985. SL Green acquired a 100% fee simple interest in the Property in 1983. Upon
completion of the Formation Transactions, such fee simple interest will be
transferred to the Company. The Property contains approximately 78,000 rentable
square feet (including approximately 72,000 square feet of office space and
approximately 6,000 square feet of retail space), with floor plates of
approximately 6,500 square feet.
 
    As of June 30, 1997, approximately 92% of the rentable square footage in 29
West 35th Street was leased (including space for leases executed as of June 30,
1997). The office space was 90% 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 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 $23.32 per square foot as of June 30,
    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 $1,482,682 as of June 30,
1997. Depreciation and amortization are computed on the straight-line method
over 39 years.

ACQUISITION PROPERTIES
 
   
    1372 BROADWAY.  The Company has contracted to acquire a 100% fee interest in
1372 Broadway from an unaffiliated seller. Pursuant to a contractual arrangement
with the seller, the closing for the acquisition of such fee interest may not
occur prior to January 1998. However, the Company has also contracted to
acquire, at the time of the closing of the Offering, from an unaffiliated
institutional lender, certain mortgage indebtedness that will effectively
entitle the Company to receive all of the cash flow derived from the Property at
such time. The aggregate purchase price for such fee interest and such mortgage
indebtedness is approximately $54.14 million (including $440,000 in acquisition
costs and $1.2 million in capital improvements). SL Green has been the leasing
agent of this Property since June 1, 1997.
    
 
    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 is anticipated to commence
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.
 
    The Property is located within five blocks of Times Square, arguably the
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.
 
    The Company has targeted the Fall of 1997 for commencement of a $2 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.
 
    As of June 30, 1997, approximately 84% of the rentable square footage in
1372 Broadway was leased (including space for leases that were executed as of
June 30, 1997). The following table sets forth certain information with respect

(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 $27.38 per square foot as of June 30, 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 $24.96.
    
 
(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
June 30, 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
$10.072 per $100 of assessed value. The total annual tax for 1140 Avenue of the
Americas at this rate for the 1997-98 tax year is $974,466 (at an assessed value
of $9,675,000).
    
 
    50 WEST 23RD STREET. In June 1997, SL Green obtained an option from an
unaffiliated seller to acquire a 100% fee interest in 50 West 23rd Street, a
333,000 rentable square foot 13-story Class B office building located on West
23rd Street between 5th Avenue and Avenue of the Americas in the Chelsea
submarket of Manhattan. The cost of obtaining the option was $500,000 (to be
credited against the purchase price) and the purchase price for the Property is
approximately $36.0 million (including $50,000 of acquisition costs).
 
                                       86
<PAGE>
   
In connection with the Formation Transactions, the option will be assigned to
the Operating Partnership at cost and will be exercisable through July 31, 1997.
The term of the option is extendable for up to three successive one month
periods (I.E., through October 31, 1997) at a cost of $100,000 per extension.
Under the option terms, the closing must occur within 30 days after exercise of
such option. Management of the Company intends to exercise the option and
acquire the Property at the closing of the Offering. The Company intends to
encumber the Property with an approximately $14 million first mortgage loan from
LBHI at the time of closing of the Offering. See "The Properties--Mortgage
Indebtedness."
    
 
    In addition to the foregoing, the contract of sale will provide that if, by
the date 50 West 23rd Street is acquired by the Company, there has not been
enacted into law a reduction in the federal income tax rate on capital gains in
effect on the contract date, the Company will deposit in an escrow account the
sum of $1.56 million. In the event there is enacted into law by April 16, 1998 a
reduction in such rate applicable to gains recognized on or before January 2,
1998, a portion of such escrowed amount approximately equal to the differential
between (i) the income tax payable by the seller on its capital gains
attributable to the sale of this Property and (ii) the income tax that would
have been payable on such gain in the event such reduction had been in effect at
the time of sale, will be paid to the seller and the balance will be refunded to
the Company.
 
    50 West 23rd Street was completed in 1892 and substantially renovated in
1992. The property contains approximately 333,000 rentable square feet
(including approximately 324,000 square feet of office space and approximately
9,000 square feet of retail space), with floor plates ranging from 32,000 square
feet to 6,500 square feet. The substantial renovation of 50 West 23rd Street in
1992, completed by the prior owner of the building at a cost of approximately
$15.4 million, included (i) construction of a new lobby, (ii) overhaul of
elevator mechanical systems, (iii) enhancement of electrical capacity, (iv)
replacement of HVAC and plumbing systems, (v) installation of new windows, (vi)
facade restoration and (vii) asbestos abatement.
 
    As of June 30, 1997, approximately 91% of the rentable square footage in 50
West 23rd Street was leased (including space for leases that were executed as of
June 30, 1997). The office space was 91% leased and the retail space was 100%
leased. The following table sets forth certain information with respect to the
Property:

in various industries including engineering, architecture and aerospace, three
of whom occupied 10% or more of the rentable square footage at the Property. A
naval architecture firm occupied approximately 64,700 square feet (approximately
19.3% of the Property) under a lease expiring on August 31, 2005, that provides
for annualized base rent as of June 30, 1997 of approximately $1.25 million
(approximately $19.39 per square foot). 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 New York City agency occupied approximately 64,000 square
feet (approximately 19.2% of the Property) under a lease expiring on June 30,
2010, that provides for annualized base rent as of June 30, 1997 of
approximately $700,000 (approximately $10.94 per square foot). In addition to
annualized base rent, this tenant pays real estate tax escalations and operating
escalations in excess of a base year amount.
    
 
    Also, an engineering firm occupied approximately 53,600 square feet
(approximately 16.1% of the Property) under a lease expiring on June 30, 2005,
that provides for annualized base rent as of June 30,

(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 $20.41 per square foot as of June 30,
    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 June
30, 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
$10.072 per $100 of assessed value. The total annual tax for 50 West 23rd Street
at this rate for the 1997-98 tax year is $969,027 (at an assessed value of
$9,621,000).
    
 
   
THE OPTION PROPERTIES
    
 
   
    17 BATTERY PLACE.  In July 1997, 17 Battery LLC, a limited liability company
owned by Stephen L. Green, contracted to acquire from an unaffiliated seller an
interest in 17 Battery Place for an aggregate purchase price of $59 million. 17
Battery Place contains 1.2 million rentable square feet and is comprised of two
Class B office buildings, 17 Battery Place North, a 22-story building
encompassing approximately
    
 
                                       88
<PAGE>
423,000 rentable square feet (the "North Building"), and 17 Battery Place South,
a 31-story building (the "South Building") encompassing approximately 799,000
rentable square feet located at the intersection of Battery Place and West
Street in the financial district of downtown Manhattan. SL Green has been
leasing agent and property manager at 17 Battery Place since January 2, 1996.
 
   
    During the contract period, the seller of 17 Battery Place, with the
assistance of 17 Battery LLC, will convert the South Building into two
condominium units. One unit will be comprised of portions of the basement and
the ground floor and floors 2 through 13 and will continue to function as office
space (the "Office Unit"). The second unit will be comprised of floors 14
through 31 and will be redeveloped by the seller into a residential/hotel
facility (the "Hotel Unit"). In addition, the North Building will continue to
function as office space. Pursuant to the contract of sale, 17 Battery LLC,
subject to the satisfactory completion of the condominium conversion, will
acquire all of the North Building and the Office Unit (an aggregate of
approximately 800,000 rentable square feet) but will have no interest in the
Hotel Unit.
    
 
    As of June 30, 1997, the North Building and the South Building were 71% and
93% leased, respectively. Tenants include MCI Communications, the City of New
York and New York Association for New Americans. 17 Battery LLC has agreed to
keep vacant until December 31, 1998 an aggregate of 153,000 square feet of
office space in the North Building and the Office Unit in order to accommodate
the relocation of office tenants from the Hotel Unit.
 
   
    The Operating Partnership has been granted an option, exercisable over a 10
year period, to acquire from 17 Battery LLC its interest in the North Building
and the Office Unit at a price equal to the aggregate of (i) sums paid by 17
Battery LLC for such interest, (ii) all financing and other costs and expenses
incurred in connection with the acquisition or ownership by 17 Battery LLC of
such interest and (iii) interest on all such sums from the date of incurrence.
    
 
    In addition to the foregoing, 17 Battery LLC has agreed during the 10 year
option term, not to sell or otherwise transfer its interest in 17 Battery Place
to any third party without providing 30 days prior notice to the Operating
Partnership and offering to the Operating Partnership the right to (i) exercise
its option under the aforementioned terms and sell its interest to such third
party or (ii) retain such option following the sale to such third party. In the
event the Operating Partnership elects not to exercise its option and a third
party sale is consummated, 17 Battery LLC will pay to the Operating Partnership
its net after tax profit from such sale (defined as the excess of the gross
sales price for 17 Battery LLC's interest over the total of any outstanding
mortgage or other encumbrance, the federal income tax payable by the members of
17 Battery LLC as a result of the sale as well as other transaction costs
incurred in connection with such sale, including transfer taxes, closing
adjustments, brokerage commissions, legal fees and accounting fees).
 
   
    110 EAST 42ND STREET.  In August 1997, 110 Realty LLC, a limited liability
company owned by Stephen L. Green, contracted to acquire from an unaffiliated
seller the land and building located at 110 East 42nd Street for a purchase
price of $30 million.
    
 
   
    110 East 42nd Street is an 18-story Class B office building containing
approximately 250,000 rentable square feet. The property is located in midtown
Manhattan on the south side of 42nd Street between Park and Lexington Avenues,
directly opposite the main entrance to Grand Central Terminal (with additional
frontage and entrances on the north side of 41st Street). As of June 30, 1997,
the building was 93% leased. Major tenants include Greenpoint Savings Bank,
Major League Soccer LLC and Morgan, Lewis & Bockius. The building was completed
in 1921 as the headquarters of the Bowery Savings Bank and has been designated
as a landmark structure by the Landmarks Commission of the City of New York.
    
 
   
    The Operating Partnership has been granted an option, exercisable over a 10
year period, to acquire from 110 Realty LLC its interest in 110 East 42nd Street
at a price equal to the aggregate of (i) sums paid by 110 Realty LLC for such
interest, (ii) all financing and other costs and expenses incurred in connection
with the acquisition of ownership by 110 Realty LLC of such interest and (iii)
interest on all such sums from the date of incurrence.
    
 
   
    In addition to the foregoing, 110 Realty LLC has agreed to substantially the
same restrictions on and effects of a sale or transfer of its interest as
described above with respect to 17 Battery LLC. Also, in the
    
 
                                       89
<PAGE>
   
event that 110 Realty LLC or an entity in which it owns an interest acquires 110
East 42nd Street and at such time the Operating Partnership has not exercised
its option, at any time prior to the expiration of the option period 110 Realty
LLC shall, at the request of the Operating Partnership, enter into an option
agreement containing commercially reasonable terms to sell 110 Realty LLC's
interest in the property to the Operating Partnership for a purchase price equal
to that set forth in (i), (ii) and (iii) of the paragraph above.
    
 
   
    Exercise of each of the options to acquire 17 Battery Place and 110 East
42nd Street by the Company is subject to approval by the independent Directors
of the Company. Accordingly, there can be no assurance that either of such
Properties will be acquired by the Company.
    
 
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 Offering, the Company expects to have outstanding
approximately $46.5 million of indebtedness secured by four of the Properties.
 
    The Company currently is negotiating with each of its lenders (and the
Property-owning entities are negotiating with each of their lenders) regarding
the terms of the indebtedness that will be outstanding after the Offering. The
following table sets forth the mortgage debt of the Company expected to be
outstanding after completion of the Offering and the Formation Transactions and
the Company's best estimate of the expected terms of such indebtedness.

CREDIT FACILITY
    
 
   
    Subject to negotiation of mutually satisfactory covenants and other terms,
LBHI has agreed to provide the Company with a revolving $75 million Credit
Facility that will be used to facilitate acquisitions and for working capital
purposes. Although the Company expects that the Credit Facility will be
established shortly after the completion of the Offering, there can be no
assurance at this time as to whether the Company will be successful in obtaining
the Credit Facility, or, if the Credit Facility is established, the terms
governing the Credit Facility.
    
 
ENVIRONMENTAL MATTERS
 
    The Company engaged independent environmental consulting firms to perform
Phase I environmental site assessments on the Properties, in order to assess
existing environmental conditions. All of the Phase I assessments have been
conducted since 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 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.
 
    The following summarizes certain environmental issues described in the Phase
I environmental site assessment reports:
 
    The asbestos surveys conducted as part of the Phase I site assessments
identified immaterial amounts of damaged, friable asbestos-containing material
("ACM") in isolated locations in three of the Core Properties (470 Park Avenue
South, 29 West 35th Street and the Bar Building) and in the Acquisition
Properties (1140 Avenue of the Americas and 1372 Broadway). At each of these
Properties, the environmental consultant recommended abatement of the damaged,
friable ACM. At all of the Properties except 50 West 23rd Street, non-friable
ACM, in good condition, was identified. For each of these Properties, the
consultant recommended preparation and implementation of an asbestos Operations
and Maintenance ("O & M") program, to monitor the condition of ACM and to ensure
that any ACM that becomes friable and damaged is properly addressed. The Company
does not believe that any risks associated with ACM are likely to have a
material adverse effect on the Company's business.
 
                                       91
<PAGE>
    The Phase I environmental site assessments identified minor releases of
petroleum products at the Bar Building and at 70 West 36th Street. The
consultant recommended implementation of certain measures to further
investigate, and to clean up, these releases. The Company does not believe that
any actions that may be required as a result of these releases will have a
material adverse effect on the Company's business.
 
PROPERTY MANAGEMENT AND LEASING SERVICES
 
    The Company (through the Management Entities and the Leasing Corporation)
will conduct its management and leasing business largely in the same manner as
it currently is conducted by SL Green. SL Green currently provides management
and leasing services for 29 properties (including the Properties in the Core
Portfolio) in the New York metropolitan area. Of these properties, SL Green
currently has an ownership interest in the six Properties in the Core Portfolio
to be owned by the Company.
 
    SL Green's management and leasing business is an established office property
management and leasing business with extensive experience. SL Green has been
managing and leasing Manhattan office properties since 1981. SL Green seeks to
provide tenants with a level of service more typically found in Class A
properties. The Company's comprehensive tenant service program and property
amenities have been designed to maximize tenant satisfaction and retention as
well as to establish long-term relationships with its tenant base. See "Business
and Growth Strategies" above.
 
    The Company believes that its fully integrated management structure enhances
its ability to respond to tenant needs and permits the Company to maintain
control over certain costs associated with the management and renovation of its
properties. The Company maintains a staff of 40 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
and anticipate the current and future space needs of tenants in its submarkets.
See "Business and Growth Strategies" above.
 
   
    After the completion of the Offering and the Formation Transactions, the
Company (through the Management LLC) will provide management and leasing
services for the Properties to be owned by the Company as well as leasing
services for a portion of the properties in which the Company will own no
interest. In addition, it is anticipated that the Company (through the
Management Corporation and the Leasing Corporation) will provide 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) will conduct the construction business largely in the same manner as
it currently is conducted by SL Green. Construction services will be provided
both 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 1.5% to 5% of costs 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
 
                                       92
<PAGE>
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 will charge from 5% to 10% 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 initially intends to employ approximately 50 persons. Of such 50
employees, approximately 48 will be "home office" executive and administrative
personnel and approximately two will be on-site management and administrative
personnel. Following the completion of the Offering and the Formation
Transactions, the Company currently expects that none of these employees will be
represented by a labor union.
 
TRANSFER OF PROPERTIES
 
    Interests in the Properties in the Core Portfolio will be acquired by the
Company (through the Operating Partnership) pursuant to agreements for
contribution of interests (each a "Contribution Agreement"). The acquisitions
are subject to all of the terms and conditions of such agreements. The holders
of interests in the Property-owning entities (which own partial or complete
interests in the individual Properties) will transfer their interests to
entities controlled by the Company for cash or Units. The Company will assume
all the rights, obligations and responsibilities of the contributors of
interests. The transfer of ownership interests in each Property is subject to
the completion of the Offering.
 
    The Contribution Agreements generally contain representations only with
respect to the ownership of the interests by the holders thereof and certain
other limited matters. Pursuant to a Supplemental Representations and Warranties
Agreement (the "Supplemental Agreement"), certain SL Green entities will agree
to indemnify the Company against certain breaches of representations and
warranties made by such SL Green entities with respect to the Properties and the
management, leasing and construction businesses being transferred to the Company
for a period of 12 months following the completion of the Offering. The maximum
aggregate liability of such SL Green entities under the Supplemental Agreement
is limited to $20 million of the Units received by the SL Green entities in the
Formation Transactions, with no liability being assumed until the aggregate
liability exceeds $250,000. Recourse for any liabilities under the Supplemental
Agreement will be limited to Units received by such SL Green entities in the
Formation Transactions. Certain SL Green entities will pledge an aggregate of
$20 million of Units (based on the initial public offering price of shares of
Common Stock) to secure their indemnification obligations under the Supplemental
Agreement.
 
ASSETS NOT BEING TRANSFERRED TO THE COMPANY
 
   
    In addition to the interests of SL Green in the Properties which are being
acquired by the Company and the Option Properties, SL Green also owns interests
in certain other properties which the Company will not acquire at the time of
the completion of the Offering and the Formation Transactions. These interests
are (i) a portion of a net leasehold interest scheduled to expire in 2000, in a
substantially vacant showroom building located at 305 East 63rd Street in
Manhattan which is slated for conversion to residential space, (ii) a one-third
non-controlling interest in a loft building located at 133 West 21st Street in
Manhattan substantially occupied by one tenant pursuant to leases scheduled to
expire in the near term, (iii) the net leasehold of an office building located
at 215 Park Avenue South in Manhattan, the equity in which is controlled by the
leasehold mortgagee and which the Company believes has no value to SL Green,
(iv) interests in ground floor retail and other non-office commercial space in
various predominantly
    
 
                                       93
<PAGE>
residential buildings located in Manhattan (830/832 Broadway, 5 East 16th
Street, 12 East 12th Street, 8 East 12th Street and 30 West 15th Street) and (v)
an 89% interest in a warehouse/distribution center in Bethlehem, Pennsylvania.
 
    The Company also will not acquire at the time of the completion of the
Offering any interest in certain office property service businesses currently
conducted by companies which are owned by a son of Stephen L. Green. These
services include office cleaning (and related) services and security services
with respect to the Company's properties and properties in which the Company
will not own any interest, as well as facilities management services with
respect to third parties. The interests in these service businesses are not
being transferred to the Company at the time of the completion of the Offering
in order to maintain the Company's qualification as a REIT for Federal income
tax purposes or because the Company does not believe such services are directly
related or material to the Company's business strategy.
 
    After the completion of the Offering, the Company may retain two entities
(both of which are owned by a son of Stephen L. Green) to provide cleaning and
security services for the Properties. Such services would be provided to the
Company at competitive rates. The Company expects these services would be
provided under contracts with such SL Green entities with an initial one-year
term, but will be terminable by either party upon 30 days' notice. Any actions
with respect to the contracts to provide these services that may be taken by the
Company in the future would need to be approved by a vote of the disinterested
members of the Board of Directors of the Company. See "Policies With Respect To
Certain Activities-- Conflict of Interest Policies." After the completion of the
Offering, certain employees of the Management LLC will supervise the provision
of cleaning and security services by SL Green entities with respect to the
Company's properties.
 
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 378 million rentable
square feet in Manhattan approximately 205 million rentable square feet is
comprised of Class A office space and 173 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 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
 
                                       94
<PAGE>
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. 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 legal proceedings. Certain SL
Green entities are parties to a variety of legal proceedings relating to their
ownership of the Properties in the Core Portfolio and SL Green's activities with
regard to its construction, management and leasing businesses, respectively,
arising in the ordinary course of business. Because the Company may be acquiring
certain of the Properties subject to associated liabilities, it may therefore
become a successor party-in-interest to certain of these proceedings as a result
of the Formation Transactions. 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, DIRECTOR NOMINEES AND EXECUTIVE OFFICERS
 
    The Board of Directors of the Company will be expanded immediately following
the completion of the Offering to include the director nominees named below,
each of whom has been nominated for election and has consented to serve. Upon
election of the director nominees, a majority of directors will not be employees
or affiliates of the Company or SL Green. 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, director nominees and executive officers of the Company immediately
following the completion of the Offering:

provided for in the agreement, (ii) continuation of benefits provided for in the

exceptions, prohibit each of such persons from engaging, directly or indirectly,

term of three years, accrue interest at the Federal mid-term "Applicable Federal
Rate" ("AFR") as in effect from time to time, and will be secured by the Common
Stock purchased and will otherwise be 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 will receive 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
 
    Prior to the Offering, the Board of Directors will adopt, and the
stockholders will approve, the 1997 Stock Option and Incentive Plan (the "Stock
Option Plan"). On and after the closing of the Offering, the Stock Option Plan
will be administered by the Compensation Committee of the Board of Directors.
Officers and certain other employees of the Company and its subsidiaries
generally will be 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 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
 
    Prior to the completion of the Offering, the Company intends to establish an
incentive compensation plan for key officers of the Company and the Company's
subsidiaries and affiliates. This plan will provide for payment of cash bonuses
to participating officers after an evaluation of the officer's performance and
 
                                      101
<PAGE>
the overall performance of the Company has been completed. The Chief Executive
Officer will make recommendations to the Compensation Committee of the Board of
Directors, which will make 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
 
    Effective upon the completion of the Offering, the Company intends to
maintain 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 will permit 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 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
 
                                      102
<PAGE>
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
 
    Following the completion of the Offering and the Formation Transactions, the
operations of the Company will be carried on through the Operating Partnership.
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 OPERATING PARTNERSHIP.  Following the completion of the Offering and the
Formation Transactions, substantially all of the Company's assets will be held
by, and its operations conducted through, the Operating Partnership and its
subsidiaries and affiliates. The Company is the sole general partner of the
Operating Partnership and will have 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 will manage the affairs of the Company by directing the
affairs of the Operating Partnership. The Operating Partnership will continue
until December 31, 2095, unless sooner dissolved or terminated. 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 will 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 therein and will entitle the Company to vote on
substantially all matters requiring a vote of the limited partners.
 
    Following the completion of the Offering and the Formation Transactions, the
Company initially will own an approximate 81.9% interest in the Operating
Partnership. Certain participants in the Formation Transactions, including
entities owned by Stephen L. Green, will own the remaining Units. The Operating
Partnership anticipates that it will acquire additional properties in exchange
for Units in the future, in which case partners in the partnerships that own
such properties will become limited partners of the Operating Partnership.
 
    After the completion of the Offering and the Formation Transactions, the
Operating Partnership expects to make regular quarterly cash distributions to
its partners (including the Company) in proportion to their percentage interests
in the Operating Partnership. The Company, in turn, will pay cash dividends to
its stockholders in an amount per share of Common Stock equal to the amount
distributed by the Operating Partnership per Unit. In addition, after a holding
period of up to two years following the completion of the Offering, 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. In the event that the Company elects to acquire Units in exchange
for shares of Common Stock upon the exercise of a redemption right by a limited
partner, each such acquisition will increase the Company's percentage ownership
interest in the Operating Partnership and will decrease the aggregate percentage
ownership interest of the limited partners (other than the Company) in the
Operating Partnership.
 
    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 will be conducted through
the Management Corporation. The Company, through the Operating Partnership, will
own 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
 
                                      104
<PAGE>
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)
will be held by the Service Corporation LLC. This controlling interest will give
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, will be conducted through the Management LLC. The Operating
Partnership will own 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, will be conducted
through the Leasing Corporation. The Company, through the Operating Partnership,
will own 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) will be held by the
Service Corporation LLC. This controlling interest will give 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 will be conducted through the Construction
Corporation. The Company, through the Operating Partnership, will own 100% of
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) will be held by
the Service Corporation LLC. This controlling interest will give the Service
Corporation LLC the power to elect all directors of the Construction
Corporation.
 
FORMATION TRANSACTIONS
 
    The following Formation Transactions have been consummated or will be
consummated concurrently 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).
    
 
    - LBHI entered into the LBHI Loan with Green Realty LLC pursuant to which
      LBHI agreed to loan up to $46 million to acquire interests in the Core
      Portfolio and the Acquisition Properties, to fund property related
      operating expenses, to fund organizational expenses of the Company and to
      purchase Treasury Securities. The LBHI Loan is secured by partnership
      interests in certain Property-owning entities and the Treasury Securities.
 
   
    - The Company will sell 10,100,000 shares of Common Stock in the Offering
      and will contribute the net proceeds therefrom to the Operating
      Partnership in exchange for 10,100,000 Units (which, including the
      issuance of Common Stock to Victor Capital and to the members of SL Green
      management referred to herein, will represent approximately an 81.9%
      economic interest in the Operating Partnership after the Offering).
    
 
   
    - The Operating Partnership will receive a contribution of its interests in
      the Core Portfolio as well as 100% of the non-voting common stock of
      (representing 95% of the economic interest in) the
    
 
                                      105
<PAGE>
      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 will
      issue to such entities, partners or members and holders 2,383,284 Units
      (having an aggregate value of approximately $47.7 million, based on the
      assumed initial offering price) approximately and $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 will be transferred to the Management LLC.
 
   
    - The Operating Partnership will be granted (i) an option from 17 Battery
      LLC to acquire its interest in 17 Battery Place, a property containing
      approximately 800,000 rentable square feet of office space in downtown
      Manhattan 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, an office building
      containing approximately 250,000 rentable square feet in midtown Manhattan
      from an unaffiliated seller for a purchase price of approximately $30
      million in cash. See "The Properties--The Option Properties."
    
 
    - The Operating Partnership will acquire interests in the Acquisition
      Properties for an aggregate purchase price of 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 will use approximately $82.3 million of net
      proceeds from the Offering to repay mortgage debt encumbering the Core
      Portfolio and the LBHI Loan (including approximately $9.4 million in
      proceeds drawn under the LBHI Loan to fund purchase of the Acquisition
      Properties).
 
    - The Company will issue 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.
 
    No independent third-party appraisals, valuations or fairness opinions have
been obtained by the Company in connection with the Formation Transactions.
Accordingly, there can be no assurance that the value of the Units and other
consideration received in the Formation Transactions by persons or entities
contributing interests in the Core Portfolio and the Service Corporations to the
Operating Partnership is equivalent to the fair market value of such interests.
 
CONSEQUENCES OF THE OFFERING AND THE FORMATION TRANSACTIONS
 
    The Offering and the Formation Transactions will have the following
consequences:
 
    - The Operating Partnership directly or indirectly will own substantially
      all of the interests in the Properties currently owned by SL Green and its
      affiliates.
 
    - The purchasers of the Common Stock offered in the Offering will own
      approximately 93.7% of the outstanding Common Stock.
 
   
    - The Company will be the general partner of, and will own approximately
      81.9% of the ownership interests in, the Operating Partnership and 95% of
      the equity in the Service Corporations.
    
 
    If all limited partners in the Operating Partnership were to exchange their
Units for Common Stock immediately after the completion of the Offering
(notwithstanding the provision of the Partnership Agreement which prohibits such
exchange for up to two years following the completion of the Offering), but
subject to the Ownership Limit, then the participants in the Formation
Transactions would beneficially own approximately 18.1% of the outstanding
shares of Common Stock.
 
    See "Risk Factors--Conflicts of Interest in the Formation Transactions and
the Business of the Company Could Adversely Affect the Company" and "Principal
Stockholders."
 
                                      106
<PAGE>
BENEFITS TO RELATED PARTIES
 
    Certain affiliates of the Company will realize certain material benefits in
connection with the Formation Transactions and the Offering, including the
following:
 
   
    - Certain continuing investors (including Stephen L. Green, members of his
      immediate family and unaffiliated partners in the Property-owning
      entities) will receive 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 $47.7 million, based on the assumed initial public offering
      price (representing approximately 18.1% of the equity of the Company on a
      fully-diluted basis).
    
 
    - The Operating Partnership will use $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, will be 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 that initially will have a value
      of $11.1 million, based on the assumed initial public offering price.
    
 
   
    - 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) will become officers and/or directors of the
      Company. In addition, each of such persons will enter into employment and
      noncompetition agreements with the Company. See "Management--Employment
      and Noncompetition Agreements." Also, the Company will grant to directors,
      officers and employees of the Company options to purchase an aggregate of
      660,000 shares of Common Stock at the initial public offering price under
      the Company's stock option and incentive plan, subject to certain vesting
      requirements. In addition, pursuant to the terms of their employment
      agreements, Messrs. Nettina and Klein will receive loans to purchase
      Common Stock to be issued under such plan in the principal amount of
      $300,000 and $500,000, respectively. See "Management."
    
 
   
    - The structure of the Formation Transactions will provide the Unit
      recipients (including Stephen L. Green, members of his immediate family
      and unaffiliated partners in the Property-owning entities) 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 will 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 will be 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 receiving Units in the Formation Transactions
      (including entities owned by Stephen L. Green) will have registration
      rights with respect to shares of Common Stock issued in exchange for
      Units.
 
    See "Risk Factors--Conflicts of Interests in the Formation Transactions and
the Business of the Company Could Adversely Affect the Company," "Management"
and "Certain Relationships and Transactions."
 
                  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
 
                                      107
<PAGE>
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.
 
    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, upon completion of the Formation
Transactions, the Company will acquire 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.
 
                                      108
<PAGE>
    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 the Formation Transactions and the
Business of the Company Could Adversely Affect the Company" and "--Limitations
on Ability to Sell or Reduce the Mortgage Indebtedness on Certain Properties
Could Adverseley 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.
 
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 Offering and the Formation Transactions, the Debt
Ratio of the Company will be approximately 15.0%. 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
 
                                      109
<PAGE>
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 Offering, 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, 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 the Formation Transactions and
the Business of the Company Could Adversely Affect 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
 
                                      110
<PAGE>
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.
After the Formation Transactions, SL Green will continue 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 will not have any interest in
these properties or businesses. See "The Properties--Assets Not Being
Transferred to the Company."
 
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 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 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 Offering, the Company may
retain 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
provide 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). After the completion of the Offering, Classic Security may continue 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
 
                                      112
<PAGE>
Limited Partnership Act (the "Act"). The Units have not been and are not
expected to be registered 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
 
                                      113
<PAGE>
sale pursuant to foreclosure of a mortgage securing the debt (or other similar
event). 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 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
 
                                      114
<PAGE>
respect to the Units originally issued with respect to 673 First Avenue and 470
Park Avenue South, (ii) the 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
 
                                      115
<PAGE>
general partner in place of the Company); and (v) on or after January 1, 2046,
at the option of the 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 Offering, limited
partners (other than the Company) will be permitted to transfer all
 
                                      116
<PAGE>
or any portion of their Units without restriction as long as they satisfy
certain requirements set forth in the 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 Offering
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.
 
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"). Upon
completion of the Offering, 10,779,216 shares of Common Stock will be issued and
outstanding (12,294,216 shares if the Underwriters' over-allotment option is
exercised in full) and no shares of Preferred Stock will be 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 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 and the Company
has no present plans to issue any Preferred Stock.

<PAGE>
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.
 
    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. In the event the Company issues Preferred Stock, it may, in the
Articles Supplementary creating such Preferred Stock, determine a limit on the
ownership of such stock. 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.
 
                                      120
<PAGE>
    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 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.
 
                                      121
<PAGE>
    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 AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.

    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
will expire 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.
 
    See "Management--Directors, Director Nominees 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.

<PAGE>
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. 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
 
                                      124
<PAGE>
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 Offering, the Company will have outstanding
10,779,216 shares of Common Stock (12,294,216 shares if the Underwriters'
overallotment option is exercised in full). In addition, 2,383,284 shares of
Common Stock are reserved for issuance upon exchange of Units. The shares of
Common Stock issued in the 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." The Company intends to issue options to purchase
approximately 660,000 shares of Common Stock to directors, officers and certain
key employees prior to the completion of the Offering and has reserved 440,000
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.
 
    Prior to the Offering, there has been no public market for the Common Stock.
Trading of the Common Stock on the New York Stock Exchange is expected to
commence immediately following the completion of the Offering. 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 stockholders of
the Company. The specific tax consequences of owning Common Stock 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 his own tax
advisors to determine the interaction of his individual tax situation with the
anticipated tax consequences of owning Common Stock.
 
    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 give a detailed discussion of 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 ending 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
 
                                      127
<PAGE>
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 "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.
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
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
 
                                      128
<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 issuing
sufficient shares of Common Stock in the Offering with sufficient diversity of
ownership to allow the Company to satisfy conditions (v) and (vi) immediately
following the Offering. 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
 
                                      129
<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 ending 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.
 
                                      130
<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 are unavailable if the Company fails
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.
 
    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
 
                                      131

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 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 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.
 
                                      132
<PAGE>
    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.
 
TAXATION OF STOCKHOLDERS
 
   
    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. 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 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 shares of Common Stock 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, any loss upon a sale or exchange of shares of Common Stock by a
stockholder which has held such shares of Common Stock 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 proposed regulations regarding the withholding and
information reporting rules discussed above. In general, the proposed
regulations do not alter the substantive withholding and information reporting
requirements but unify
 
                                      133
<PAGE>
current certification procedures and forms and clarify and modify reliance
standards. If finalized in their current form, the proposed regulations would
generally be effective for payments made after December 31, 1997, 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 a tax-exempt entity.
Based on that ruling, the dividend income from the Common Stock will not be UBTI
to a tax-exempt stockholder, provided that the tax-exempt stockholder has not
held its shares of Common Stock 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 Common Stock 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 FOREIGN 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
 
                                      134
<PAGE>
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 current Treasury Regulations, dividends paid to an address in a
country outside the United States are generally 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. Under
proposed Treasury Regulations, not currently in effect, however, a Non-U.S.
Stockholder who wishes to claim the benefit of an applicable treaty rate would
be required to satisfy certain certification and other requirements.
 
    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.
 
    COMMON STOCK SALES. Gain recognized by a Non-U.S. Stockholder upon a sale or
exchange of shares of Common Stock 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 Common Stock will be publicly traded, no assurance
can be given that the Company will continue to so
 
                                      135
<PAGE>
qualify. If the Company were not a domestically controlled REIT, whether or not
a Non-U.S. Stockholder's sale of shares of Common Stock would be subject to tax
under FIRPTA would depend on whether or not the shares of Common Stock were
regularly traded on an established securities market (such as the NYSE, on which
the Company has applied for the listing of the shares of Common Stock) and on
the size of the selling Non-U.S. Stockholder's interest in the Company. If the
gain on the sale of shares of Common Stock 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 shares of Common Stock may be
required to withhold 10% of the gross purchase price.
 
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 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 will be 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").
 
                                      136
<PAGE>
    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
Purchaser who contributed the Property. These 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
assets of the Operating Partnership is increasing at a commensurate rate.
 
STATE AND LOCAL TAX
 
   
    The Company and its stockholders may be subject to state and local tax in
states and localities in which it does business or owns property. The tax
treatment of the Company and the stockholders in such jurisdictions may differ
from the Federal income tax treatment described above.

    The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase shares of Common Stock are subject to certain
conditions, and that if any of the shares of Common Stock are purchased by the
Underwriters pursuant to the Underwriting Agreement, all of the shares 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
shares of Common Stock 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 share. The selected dealers
may reallow a concession not in excess of $         per share to certain brokers
or dealers. After the 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 1,515,000 shares of Common Stock 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
shares of Common Stock 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 Inc., 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 addition, certain SL Green entities and certain officers of the Company
have agreed that they will not, without the prior written consent of the Company
and Lehman Brothers Inc., 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 Offering, for an initial period of one year after the date
of this 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 this
Prospectus. Also, Victor Capital has agreed to similar restrictions with respect
to the shares of Common Stock received by it in connection with the Formation
Transactions for a period of one year after the date of this 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.
 
    The Underwriters do not intend to confirm sales of Common Stock to any
account over which they exercise discretionary authority.
 
    Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price will be determined through negotiations
between the Company and the Representatives. Among the factors to be considered
in such negotiations, in addition to prevailing market conditions, are
distribution rates and financial characteristics of publicly traded REITs that
the Company and the Representatives believe to be comparable to the Company, the
expected results of operations of the Company (which are based on the results of
operations of the Properties in recent periods), estimates of future business
potential and earnings prospects of the Company as a whole and the current state
of the real estate market in the Midtown Markets and the economy as a whole. The
initial price per share to the public set forth on the cover page of this
Prospectus should not, however, be considered an indication of the actual value
of the Common Stock. Such price is subject to change as a result of market
conditions and other factors.
 
    The shares of Common Stock have been approved for listing on the NYSE,
subject to official notice of issuance, under the symbol "SLG."
 
    Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase the Common Stock. As an exception to these
rules, the Representatives are permitted to engage in certain transactions that
stabilize the price of the Common Stock. Such transactions consist of bids or
purchases for the purpose of pegging, fixing or maintaining the price of the
Common Stock.
 
    If the Underwriters create a short position in the Common Stock in
connection with the offering, I.E., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus, the Representatives may
reduce that short position by purchasing Common Stock in the open market. The
Representatives may also elect to reduce any short position by exercising all or
part of the over-allotment option described herein.
 
    The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of the 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
 
                                      139
<PAGE>
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 Common Stock. 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.
 
   
    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. The Company will pay an advisory fee equal to 0.75% of
the gross proceeds of the Offering (including any exercise of the Underwriters'
overallotment option) to Lehman for advisory services in connection with the
evaluation, analysis and structuring of the Company's formation as a REIT. In
connection with the Offering, an affiliate of Lehman Brothers Inc. will receive
$39.6 million of the net proceeds in repayment of amounts outstanding under the
LBHI Loan. In addition, LBHI is expected to provide the Operating Partnership
with a $14 million mortgage loan secured by 50 West 23rd Street and will receive
an administrative fee of up to .02% in connection with a line of credit being
arranged for the Company in anticipation of the establishment of the Credit
Facility by the Company and LBHI. See "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources," "The Properties--Credit Facility"
and "Certain Relationships and Transactions."
    
 
    Although the Conduct Rules of the National Association of Securities
Dealers, Inc. exempt 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 financial
advisory fee and in repayment of currently outstanding indebtedness, 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 "Independent
Underwriter") is assuming the responsibilities of acting as "qualified
independent underwriter," and will recommend the maximum initial public offering
price for the Common Stock in compliance with the requirements of the Conduct
Rules. In connection with the Offering, the Independent Underwriter is
performing due diligence investigations and is reviewing and participating in
the preparation of this Prospectus and the Registration Statement of which this
Prospectus forms a part. The initial public offering price of the Common Stock
will be no higher than the price recommended by the Independent Underwriter.
 
    The Underwriters have reserved for sale at the public offering price up to
505,000 shares of Common Stock to directors, officers, employees and consultants
of the Company, their business affiliates and related parties who have expressed
an interest in purchasing shares. The number of shares available for sale to the
general public will be reduced to the extent such persons purchase the reserved
shares. Any reserved shares not so purchased will be offered by the Underwriters
to the general public on the same basis as the others have been offered hereby.

                                  (UNAUDITED)
 
    The pro forma balance sheet of the Company as of June 30, 1997 has been
prepared as if the Offering and Formation Transactions had been consummated on
June 30, 1997. The pro forma statements of income for the six months ended June
30, 1997 and for the year ended December 31, 1996 are presented as if the
completion of the Offering and the Formation Transactions occurred at January 1,
1996 and the effect thereof was carried foward through the six month period
ended June 30, 1997.
 
    The pro forma financial statements do not purport to represent what the
Company's financial position or results of operations would have been assuming
the completion of the Formation Transactions and the Offering on such date or at
the beginning of the period indicated, nor do they purport to project the
Company's financial position or results of operations at any future date or for
any future period. The pro forma combined financial statements should be read in

              ADJUSTMENTS TO THE PRO FORMA COMBINED BALANCE SHEET
 
    (A) To reflect the SL Green Predecessor historical combined balance sheet as
of June 30, 1997. The real estate and other assets and the assumption of
liabilities and deficit of the SL Green Predecessor will be transferred at their
historical amounts to the Operating Partnership.
 
   
    (B) To reflect 673 First Avenue, 470 Park Avenue South and 29 West 35th
Street (the "Equity Properties") as consolidated entities rather than as
uncombined joint ventures as a result of the acquisition of 100% of the
partnerships' interests and to record payment of transfer costs on the transfer
of the properties to the Operating Partnership. The Company will account for
interests acquired from third parties (the other partners), by the purchase
method.

    (C) To reflect adjustments required to record the Company's investments in
the Service Corporations pursuant to the equity method of accounting. As a
result of the Formation Transactions the Company will not own the majority of
the voting stock of the Service Corporations but will continue to exercise
significant influence due to the following:
   
        --Substantially all of the economic benefits flow to the Company (who
    will own 100% of the non-voting common stock representing 95% of the total
    equity).
    
        --The Company and the Service Corporations have common officers and
    employees.
        --The owners of a majority of the voting stock of the Service
    Corporations have not contributed substantial equity to the Service
    Corporations.
        --The views of the Company's management influence the operations of the
    Service Corporations.
 
    The adjustment is as follows:

    (P) Represents the 18.1% interest of the minority in the Operating
Partnership.
    
 
   
    (Q) Pro Forma net income per common share is based upon 10,779,216 shares of
common stock expected to be outstanding after the Offering. As each Operating
Partnership Unit is redeemable for cash, or at the company's election, for one
share of common stock, the calculation of earnings per share upon redemption
will be unaffected as unitholders and stockholders share equally on a per unit
and per share basis in the net income of the Company. In February 1997, the
Financial Accounting Standards Board issued Statement No. 128, Earnings per
Share, which is required to be adopted on December 31, 1997. At that time the
Company will be required to change the method currently used to compute earnings
per share and to restate all prior periods. Under the new requirements for
calculating primary earnings per share, the dilutive effect of stock options
will be excluded. Management does not believe the adoption of Statement No. 128
will have a material impact on earnings per share.

    (C) To reflect adjustments to record the Company's share in the net income
of the Service Corporations pursuant to the equity method of accounting for the
year ended December 31, 1996. As a result of the Formation Transactions the
Company will not own any voting stock of the Service Corporations but will
continue to exercise significant influence due to the following:
 
   
    - Substantially all of the economic benefits flow to the Company (who will
     own 100% of the non-voting common stock representing 95% of the total
     equity)
    
 
    - The Company and the Service Corporations have common officers and
     employees
 
    - The owners of a majority of the voting stock of the Service Corporations
     have not contributed substantial equity to the Service Corporations
 
    - The views of the Company's management influence the operations of the
     Service Corporations

Partnership.
 
    (H) Pro Forma net income per common share is based upon 10,779,216 shares of
common stock expected to be outstanding after the Offering. As each Operating
Partnership unit is redeemable for cash, or at the company's election, for one
share of common stock, the calculation of earnings per share upon redemption
will be unaffected as unitholders and stockholders share equally on a per unit
and per share basis in the net income of the Company. In February 1997, the
Financial Accounting Standards Board issued Statement No. 128, Earnings per
Share, which is required to be adopted on December 31, 1997. At that time the
Company will be required to change the method currently used to compute earnings
per share and to restate all prior periods. Under the new requirements for
calculating primary earnings per share, the dilutive effect of stock options
will be excluded. Management does not believe the adoption of Statement No. 128
will have a material impact on earnings per share.

                             NOTES TO BALANCE SHEET
 
                                 JUNE 12, 1997
 
1. ORGANIZATION AND FORMATION TRANSACTIONS
 
FORMATION AND INITIAL PUBLIC OFFERING
 
    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 will receive a contribution of interests 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 expects to qualify as a real estate investment trust ("REIT") under the
Internal Revenue Code of 1986, as amended; and will operate 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 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. In connection with the formation of the Company, the Company
issued 1,000 shares of Common Stock to Stephen L. Green at $1 per share, for an
aggregate consideration of $1,000 consisting of cash. At the conclusion of the
Offering such shares of stock will be repurchased by the Company at cost. As of
June 12, 1997, no shares of Excess Stock or Preferred Stock are issued and
outstanding. The Company expects to issue 10,100,000 shares of its Common Stock
to the public through a public offering (the "Offering"). In addition, the
Company expects to issue to its executive officers approximately 553,616 shares,
as founders' shares.
 
    Substantially all of the Company's assets will be held by, and its
operations conducted through, the Operating Partnership, a newly formed Delaware
limited partnership. The Company will be the sole managing general partner of
the Operating Partnership. Continuing investors will expect to hold, in the
aggregate, a 18.1% limited partnership interest in the Operating Partnership.
 
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 will be conducted through the Service
Corporations. The Company, through the Operating Partnership, will own 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 expects to receive substantially all of the cash flow from the
Service Corporations' operations. All of the voting common stock of the Service
Corporations (representing 5% of the total equity) will be held by an SL Green
affiliate. This controlling interest will give the SL Green affiliate the power
to elect all directors of the Service Corporations. All of the management and
leasing with respect to the properties to be contributed and to be acquired by
the Company will be conducted through the Management LLC. The Operating
Partnership will own a 100% interest in the Management LLC. The Company will
account for its investment in the Service Corporations on the equity basis of
accounting on the basis that it will have significant influence with respect to
management and operations. For further description, see the caption "Structure
and Formation of the Company".

1. ORGANIZATION AND FORMATION TRANSACTIONS (CONTINUED)
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, as described further under the caption
"Partnership Agreement Transfer of Interest--Redemption of Units".
 
INITIAL PUBLIC OFFERING AND USE OF PROCEEDS
 
    The net cash proceeds to be received by the Company from the Offering (after
deducting underwriting discounts) are estimated to be approximately $189.4
million. Of this amount the Company expects that approximately $42.7 million to
repay mortgage indebtedness encumbering the properties, including $1.9 million
for prepayment penalties and other financing fees and expenses, approximately
$6.4 million to purchase the direct or indirect interests of certain
participants in the Formation Transactions in the properties, approximately
$99.0 million to acquire properties (including a $1.6 million escrow account
established in connection with the acquisition of 50 W. 23rd Street),
approximately $6.1 million to pay certain expenses incurred in the Formation
Transactions, $27.5 million to repay the LBH Inc. Loan (excluding $2.5 million
and $200,000 borrowed under the loan to fund offering expenses and prepayment
penalties, respectively), and $9.4 million to acquire properties), $1.5 million
to fund the advisory fee payment to Lehman Brothers, Inc. and $6.2 million to
fund capital expenditures and general working capital needs.
 
    If the underwriters' over-allotment option to purchase 1.515 million shares
of Common Stock is exercised, the Company will use the additional net proceeds
(estimated to be approximately $28.2 million if the option is exercised in full)
to acquire an additional interest in the Operating Partnership which will be
used to acquire additional properties and/or for working capital.
 
2. STOCKHOLDER'S EQUITY
 
COMMON STOCK
 
    The authorized capital stock of the Company will consist of 200,000,000
shares of capital stock, $.01 par value, of which 100 million shares initially
will be designated as shares of Common Stock. 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.

2. STOCKHOLDER'S EQUITY (CONTINUED)
RETAINED EARNINGS
 
    The Company has not engaged in any operations from inception in 1997.
 
3. COMMITMENTS AND CONTINGENCIES
 
STOCK OPTION AND INCENTIVE PLAN
 
    The Company intends to adopt a stock option plan designed to attract, retain
and motivate executive officers of the Company and other key employees and the
plan will authorize the issuance of shares of common stock pursuant to options
granted under the plan, as described further under the caption "Stock Option and
Incentive Plan."
 
INCENTIVE COMPENSATION PLAN
 
    The Company intends to establish an incentive compensation plan for key
officers of the Company and its subsidiaries and affiliates. This plan will
provide for payment of cash bonuses to participating officers after an
evaluation of the officer's performance and the overall performance of the
Company. The Compensation Committee of Board of Directors will make the
determination for the award of the bonuses.
 
EMPLOYMENT AGREEMENTS
 
    The Company will enter into employment and non-competition agreements with
certain executive officers, as described further under the caption "Employment
and Non-Competition Agreements."
 
CREDIT FACILITY
 
   
    Subject to negotiation of mutually satisfactory covenants and other terms,
Lehman Brothers Holdings Inc. has agreed to provide the Company a revolving $75
million Credit Facility that will be used to facilitate acquisitions and for
working capital purposes. Although the Company expects that the Credit Facility
will be established shortly after the completion of the Offering, there can be
no assurance at this time as to whether the Company will be successful in
obtaining the Credit Facility, or, if the Credit Facility is established, the
terms governing the Credit Facility.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners, Members and Stockholders
SL Green Predecessor
 
    We have audited the accompanying combined balance sheets of SL Green
Predecessor as of December 31, 1996 and 1995, and the related combined
statements of operations, owners' deficit and cash flows for each of the three
years in the period ended December 31, 1996. We have also audited the financial
statement schedule listed on the Index to Financial Statements included in the
Prospectus. These financial statements and financial statement schedule are the
responsibility of SL Green Predecessor's management. Our responsibility is to
express an opinion on these financial statements and financial statement
schedule 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 SL Green
Predecessor at December 31, 1996 and 1995, and the combined results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1996 in conformity with generally accepted accounting principles.
Also, in our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be set
forth therein.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
    SL Green Predecessor is engaged in the business of owning, managing,
leasing, acquiring and repositioning of Class B office properties in Manhattan,
New York.
 
PROPOSED TRANSACTIONS
 
    Concurrently with the consummation of an initial public offering of SL Green
Realty Corp., (the "REIT") Common Stock (the "Offering"), which is expected to
be completed in 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"), will engage in certain formation
transactions (the "Formation Transactions"). The Formation Transactions are
designed to (i) enable the REIT to raise the necessary capital to acquire the
remaining interests in the Properties (see note 2), 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 operations of the REIT will be carried on primarily through the
Operating Partnership in order to assist the REIT and the Participants in
forming the REIT under the Internal Revenue Code of 1986. The REIT will be the
sole general partner in the Operating Partnership. The Operating Partnership
will receive a contribution of interests in the real estate properties sold, as
well as 95% of the economic interest in the management, leasing and construction
companies (the "Service Corporations") for third party properties, in exchange
for units of limited partnership interests in the Operating Partnership and/or
cash. The REIT will be fully integrated, self-administered and self-managed.
 
PRINCIPLES OF COMBINATION
 
   
    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.

(A) The minority interest is not material.
 
   
    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 (unaudited) (see note 2).
    
 
    For the entities accounted for on the equity method, the SL Green
Predecessor's 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.
 
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.
 
REAL ESTATE
 
    Financial Accounting Standards Board Statement of Financial Accounting
Standards ("SFAS") No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF, requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS No. 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. The SL
Green Predecessor, adopted SFAS No. 121 in the first quarter of 1996. Through
March 31, 1997 (unaudited) and December 31,1996 no indicators of impairment were
present and no impairment losses have been recorded in any of the periods
presented.

</TABLE>

respectively. For the unaudited three months ended June 30, 1997 depreciation
expense amounted to $488.
 
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.
 
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 sheets. Contractually due but unpaid rents are
included in receivables on the accompanying combined balance sheets.
 
DEFERRED LEASE COSTS

and renew operating leases and are amortized on a straight-line basis over the
initial lease term or renewal period as appropriate.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    The partnerships in the SL Green Predecessor 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. The management, leasing and construction entities are C-Corporations,
which have had minimal income during the three years ended December 31, 1996 and
therefore have paid minimal federal and state income taxes.
 
CREDIT RISK
 
    Management of the SL Green Predecessor performs on going credit evaluation
of its tenants and requires certain tenants to provide security deposits.
Although the SL Green Predecessors' buildings are all located in Mid-town
Manhattan, the tenants operate in various industries and there is no dependence
upon any single tenant.
 
CAPITALIZATION
 
    The Service Corporations (three) each have 200 shares of no par value common
stock authorized and issued for $1,000, with no related additional paid in
capital at December 31, 1996 and 1995.
 
INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The accompanying interim unaudited financial statements have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosure normally included in the financial
statements prepared in accordance with generally accepted accounting principles
may have been condensed or omitted pursuant to such rules and regulations,
although management believes that the disclosures are adequate to make the
information presented not misleading. The unaudited financial statements as of
June 30, 1997 and for the six month periods ended June 30, 1997 and 1996
include, in the opinion of management, all adjustments, consisting of normal
recurring adjustments, necessary to present fairly the financial information set
forth herein.
 
   
    The June 30, 1997 financial statements reflects a pro forma adjustment, with
respect to the proposed formation of the REIT. The pro forma adjustments reflect
$20,000 of the Offering proceeds will be used by the Operating Partnership to
repay a portion of a loan made to a company indirectly owned by Stephen L.
Green, which loan will be transferred to the Operating Partnership in connection
with the transfer thereto by Stephen L. Green of his ownership interests, which
has been accounted for as a distribution to Stephen L. Green.

</TABLE>
 
- ------------------------
 
(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 (unaudited).

(A) SL Green Predecessor does not have the right to prepay the principal balance
    of the mortgage, in whole or in part, prior to May 31, 2004. If the mortgage
    is prepaid prior to May 31, 2004 a prepayment fee will be required based
    upon the greater of 1% of the outstanding principal balance of the mortgage
    or yield maintenance as defined by the mortgage agreement.
 
(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.
 
   
(C) The Lehman Brothers Holdings Inc. loan is secured by partnership interests
    in certain Property-owning entities.

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 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 and variable rate mortgages are carried at amounts which
reasonably approximate their fair values.
 
    Estimated fair value is based on anticipated settlements in connection with
the REIT formation, interest rates and other related factors currently available
to the SL Green Predecessor for issuance of debt with similar terms and
remaining maturities. The fair value for each mortgage approximates its carrying
amount.
 
    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. RENTAL INCOME
 
    The Properties are being leased to tenants under operating leases with
expiration dates ranging from 1997 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 SL
Green Predecessor for increases in certain operating costs and real estate taxes
above their base year costs.

construction, management and leasing businesses, arising in the ordinary course
of business. SL Green Predecessor's 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 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 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.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners, Members and Stockholders
SL Green Predecessor
 
    We have audited the accompanying combined balance sheets of the uncombined
joint ventures of SL Green Predecessor as of December 31, 1996 and 1995 and the
related combined statements of operations, owners' deficit and cash flows for
each of the three years in the period ended December 31, 1996. We have also
audited the financial statement schedule listed on the Index to financial
statements included in the Prospectus. These financial statements and financial
statement schedule are the responsibility of SL Green Predecessor's management.
Our responsibility is to express an opinion on these financial statements and
financial statement schedule 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 1995,
and the combined results of its operations and its cash flows for each of the
three years in the period ended December 31, 1996 in conformity with generally
accepted accounting principles. Also, in our opinion the financial statement
schedule referred to above, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects, the
information required to be set forth therein.

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.
 
PROPOSED TRANSACTIONS
 
    Concurrently with the consummation of an initial public offering of SL Green
Realty Corp. (the "REIT") Common Stock (the "Offering"), which is expected to be
completed in 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"), will engage in certain formation
transactions (the "Formation Transactions"). The Formation Transactions are
designed to (i) enable the REIT to raise the necessary capital to acquire the
remaining interests in the properties 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 operations of the REIT will be carried on primarily through the
Operating Partnership in order to assist the REIT and the Participants in
forming the REIT under the Internal Revenue Code of 1986. The REIT will be the
sole general partner in the Operating Partnership. The Operating Partnership
will receive a contribution of interests in the real estate properties as well
as 95% of the economic interest in the management, leasing and construction
companies (the "Service Corporations") which service third party properties, in
exchange for units of limited partnership interests in the Operating Partnership
and/or cash. The REIT will be 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.

</TABLE>
 
(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
    (unaudited).
 
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.
 
REAL ESTATE
 
    Financial Accounting Standards Board Statement of Financial Accounting
Standards ("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of, requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS No. 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. The SL
Green Predecessor adopted SFAS No. 121 in the first quarter of 1996. Through
June 30, 1997 (unaudited), December 31, 1996 no indicators of impairment were
present and no impairment losses have been recorded in any of the periods
presented.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEPRECIATION OF REAL ESTATE PROPERTIES
 
    Depreciation and amortization is computed on the straight-line method as
follows:
 
<TABLE>
<CAPTION>
CATEGORY                                                             TERM

<S>                                             <C>
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
amounted to $2,917, $2,999 and $2,869 in 1996, 1995 and 1994 respectively. For
the unaudited six months ended June 30, 1997 depreciation expense amounted to
$1,594.
 
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.
 
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 sheets. Contractually due but unpaid rents are
included in other assets on the accompanying combined balance sheets. 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--LAND
 
    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 sheets.
 
INCOME TAXES
 
    The entities in the SL Green Predecessor 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 SL Green Predecessor's revenue for the three years
ended December 31, 1996 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 SL Green Predecessor. In addition approximately
30% of the SL Green Predecessor's revenue for the three years ended December 31,
1996 were derived from three tenants, (Society of NY Hospital, Kallir, Phillips,
Ross, Inc. and UNICEF), which lease space in the 673 First Avenue building.
 
    Management of the SL Green Predecessor performs on going credit evaluations
of its tenants and requires certain tenants to provide security deposits.
 
INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The accompanying interim unaudited financial statements have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosure normally included in the financial
statements prepared in accordance with generally accepted accounting principles
may have been condensed or omitted pursuant to such rules and regulations,
although management believes that the disclosures are adequate to make the
information presented not misleading. The unaudited financial statements as of
June 30, 1997 and for the six months ended June 30, 1997 and 1996 include, in
the opinion of management, all adjustments, consisting of normal recurring
adjustments, necessary to present fairly the financial information set forth
herein.

    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 and
    $55 were due in 1996 and 1994 respectively. These amounts were unpaid as of
    December 31, 1996.

4. 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 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 SL Green Predecessor for issuance of debt with similar terms and
remaining maturities. The fair value by mortgage type as of December 31, 1996 is
as follows:

4. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
    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.
 
5. LEASE AGREEMENTS
 
OPERATING LEASE
 
    The SL Green Predecessor is the lessor and sub-lessor of commercial
buildings under operating leases with expiration dates ranging from 1997 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.
Approximate future minimum rents to be received over the next five years and
thereafter for leases in effect at December 31, 1996 are as follows:

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.
 
    Future minimum rental payments under two land operating leases as of

7. 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, $30 and $32 in
1996, 1995 and 1994, respectively; and $27 for the six months ended June 30,
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.
 
8. CONTINGENCIES
 
    SL Green Predecessor is party to a variety of legal proceedings relating to
the ownership of the properties and SL Green Predecessor activities with regard
to its construction, management and leasing businesses respectively, 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.
 
9. 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 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.

              NOTES TO STATEMENT OF REVENUES AND CERTAIN EXPENSES
 
   
                             (DOLLARS IN THOUSANDS)
    
 
                               DECEMBER 31, 1995
 
1. BASIS OF PRESENTATION
 
    Presented herein is the statement of revenues and certain expenses related
to the operations of 1414 Avenue of the Americas, (the "Property"), located in
the borough of Manhattan in New York City.
 
    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
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 aforementioned property. Items excluded consist of interest, ground rent,
amortization and depreciation.
 
    On June 23, 1996, the SL Green Predecessor purchased the Property and the
underlining land lease.
 
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 so recognized over amounts due pursuant to the
underlying leases amounted to approximately $208 and $58 (unaudited) for the
year ended December 31, 1995 and the six months ended June 30, 1996,
respectively.
 
4. CONCENTRATION OF REVENUE
 
    Approximately 22% and 23% of 1414 Avenue of the Americas' revenue for the
year ended December 31, 1995 and the six months ended June 30, 1996,
respectively were derived from two tenants.
 
5. MANAGEMENT AGREEMENTS
 
    During 1995 and the period ended June 23, 1996 the Property was managed by
SL Green Management Corp. as agent. During the period from January 1, 1995 to
April 30, 1995 the management fee was based on four percent (4%) of gross
collections of which 25% percent of the management fee has been accrued and is
payable when the net cash flow of the Property exceeds one million dollars. From
May 1, 1995 to June 23, 1996 the management fee was based on three percent (3%)
of gross collections from the Property.
 
6. LEASE AGREEMENTS
 
    The Property is being leased to tenants under operating leases with term
expiration dates ranging from 1996 to 2010. The minimum rental amounts due under
the leases are generally subject to scheduled fixed increases. The leases
generally also require that the tenants reimburse the Property for increases in
certain operating costs and real estate taxes above their base year costs.

    Prior to the acquisition, the Property was the lessee of a triple net ground
lease with term expiration date of 2036. The minimum rental amounts due under
the ground lease is subject to scheduled fixed increases. The ground lease
requires that the tenant is responsible for the payment for all expenses. In
connection with the acquisition of the property and underlining land on June 23,
1996, by SL Green Predecessor the ground lease was terminated.
 
7. INTERIM UNAUDITED FINANCIAL INFORMATION
 
    The financial statement for the six months ended June 30, 1996 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.

                             (DOLLARS IN THOUSANDS)
    
 
                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION
 
    Presented herein is the statement 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 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
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 aforementioned 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.

accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and

    The Property is being leased to tenants under operating leases with
expiration dates ranging from 1997 to 2010. Most leases contain renewal options

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

1. BASIS OF PRESENTATION
 
    Presented herein is the statement 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 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
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 aforementioned 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.

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
 
                                      II-1
<PAGE>
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 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.

ITEM 36. UNDERTAKINGS
 
    The Registrant hereby undertakes:
 
        (1) For purposes of determining any liability under the Securities Act
    the information omitted from the form of Prospectus filed as part of the
    Registration Statement in reliance upon Rule 430A and contained in the form
    of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    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.

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 
10,100,000 shares (the "Shares") of Common Stock, par value $.01 per share 
("Common 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. 333-29329, 
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


<PAGE>

any jurisdictions other than the laws of the United States of America, the 
State of Maryland and the State of New York.  
    
    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 Common 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 our firm under the caption "Legal 
Matters" in the Prospectus.

                                       Very truly yours,

                                       /s/ Brown & Wood LLP

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

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.333-29329) of the Company initially 
filed by the Company with the Securities and Exchange Commission on June 16, 
1997, 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 ending December 31, 
1997, the Company will be organized in conformity with the requirements for 
qualification 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 common stock of 
the Company.

     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 

<PAGE>

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.
     
                                       Sincerely,

                                       /s/ Brown & Wood LLP

                                                           110 East 42nd Street


                              OPTION TO PURCHASE


    THIS OPTION TO PURCHASE (the "AGREEMENT") made this 6th day of August, 1997
by and between Green 110E42 Realty LLC, having an address at 70 West 36th
Street, New York, New York ("SELLER") and SL Green Operating Partnership, L.P.,
having an address at 70 West 36th Street, New York, New York ("PURCHASER").

    WHEREAS, Purchaser desires to acquire an option to purchase Seller's
interest as contract vendee ("SELLER'S INTEREST") of the Property, as defined in
the Contract of Sale attached hereto as Exhibit A and made a part hereof (the
"AGREEMENT OF SALE"); and

    WHEREAS, Seller desires to grant to Purchaser an option to purchase the
Seller's Interest; 

     NOW, THEREFORE, in pursuance of said agreement and in consideration of the
sum of Ten Dollars ($10.00) and other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

    1.   Seller hereby grants to Purchaser an option, upon the terms and 
conditions hereinafter set forth (the "OPTION"), to acquire the Seller's 
Interest.  The Option may be exercised by Purchaser in the manner hereinafter 
set forth from the date hereof through and including the tenth (10th) 
anniversary of the date hereof (the "OPTION PERIOD").   In the event 
Purchaser elects to exercise the Option, Purchaser shall give written notice 
thereof to Seller (the "OPTION NOTICE"), which Option Notice must (a) be 
received by Seller on or before the expiration of the Option Period and (b) 
be accompanied by Purchaser's unendorsed certified check in an amount equal 
to Seller's Investment (as defined below) to the order of Seller.  In the 
event that the Option Notice is not delivered to Seller on or prior to the 
expiration of the Option Period or the Option Notice is not accompanied by 
Purchaser's unendorsed, certified check in an amount equal to the Seller's 
Investment, the Option shall be terminated and of no further force and effect 
and neither party shall have any further rights or liabilities under this 
paragraph.  In the event the Option Notice and the Seller's Investment are 
delivered to Seller prior to the expiration of the Option Period, Seller 
shall, assign all of its right title and interest in the Agreement of Sale to 
Purchaser pursuant to an assignment in the form of EXHIBIT B attached hereto 
and made a part hereof.  As used herein "SELLER'S INVESTMENT" shall mean a 
sum equal to all funds of whatever nature invested by Seller in 

<PAGE>

connection with the acquisition of the Property, including, without limitation,
(a) all sums paid to 110 East 42nd Street Associates Limited Partnership
("OWNER") pursuant to the Agreement of Sale, (b) sums incurred in connection
with any financing of sums paid to Owner or otherwise incurred in connection
with the purchase of the Property, including, without limitation, principal and
interest and commitment and application fees, (c) all accounting, legal,
architectural, and engineering fees and expenses, (d) all other fees and
expenses incurred in connection with any of the foregoing and (e) interest on
all such sums at a rate equal to 12% from the date each such expense is actually
incurred through and including the date the Option is exercised.

    2.   Seller may not sell or otherwise transfer the Seller's Interest to any
party other than Purchaser (a "THIRD PARTY") without giving at least thirty (30)
days prior written notice (the "SALE NOTICE") of such sale or transfer to
Purchaser, which notice shall be accompanied by a copy of the proposed contract
to be executed in connection with such sale or transfer.  Upon receipt of the
Sale Notice, Purchaser may, by giving notice to Seller within fifteen (15) days,
exercise the Option on the terms contained herein and, at the sole and absolute
option of Purchaser, either sell the Seller's Interest to the Third Party on the
terms and conditions set forth in the aforementioned proposed contract, or such
other terms as Purchaser and Third Party shall subsequently agree upon, or
retain the option to purchase the Seller's Interest pursuant to the terms
hereof.  All contracts which Seller may enter into which relate to the sale or
transfer of the Seller's Interest after the date hereof shall specifically state
that they are subject and subordinate to the rights of Purchaser hereunder.  In
the event that Purchaser does not exercise the Option on the terms contained
herein and a sale or transfer of the Seller's Interest by Seller to a Third
Party is consummated, Seller shall pay to Purchaser on the date upon which such
sale or transfer is consummated, a sum equal to (a) the gross sales price for
the Seller's Interest (including normal and customary closing adjustments) minus
(b)(i) Seller's Interest, (ii) all Federal income tax payable by the partners of
Seller which results from the sale of the Property and (iii) other normal and
customary costs attributable to the sale of the Property, including, without
limitation, transfer taxes, brokerage commissions, reasonable legal fees and
reasonable accounting fees (the "NET AFTER TAX PROFIT").  Upon the payment of
Seller's Net After Tax Profit to Purchaser, this Agreement shall be terminated
and of no further force and effect and neither party shall have any further
rights or liabilities hereunder.

    3.   In the event that Seller or a partnership, corporation limited
liability company, joint venture or other entity in which Seller owns a legal or
beneficial interest acquires the Property and at such time Purchaser has not
exercised the Option, at any 

                                       2

<PAGE>

time prior to the expiration of the Option Period Seller shall, at the 
request of Purchaser, enter into an option agreement to sell Seller's 
interest in the Property to Purchaser for a purchase price equal to Seller's 
Investment which shall be in form and substance reasonably acceptable to 
Purchaser and Seller and on such other terms as are commercially reasonable 
for transactions of such type.

    4.   Seller represents and warrants that (a) it is the sole owner of, and
has good and marketable title to, the Seller's Interest, (b) Seller has not
granted an option or right of first refusal to purchase the Seller's Interest to
any party other than Purchaser and (c) Seller is not a "foreign person" within
the meaning of Section 1445 of the Internal Revenue Code, as amended, or any
regulation promulgated thereunder.

    5.   Seller covenants that (a) it will not modify the Purchase Agreement or
enter into any agreement with respect to the Property which in any way would
have a material adverse effect upon the rights of Purchaser hereunder without
Purchaser's prior written consent, which consent may be withheld or granted in
Purchaser's sole discretion and (b) that it will not purchase the Property or
give a Purchaser's Closing Notice (as defined in the Agreement of Sale) without
first giving Purchaser 15 days prior written notice and the opportunity to
exercise the Option.

    6.   Seller and Purchaser mutually represent and warrant that neither
Seller nor Purchaser know of any broker who has claimed, or may have the right
to claim, a commission or any similar finder's fee in connection with the
transaction contemplated by this Agreement.  Seller and Purchaser shall
indemnify and defend each other against any costs, claims or expenses, including
reasonable attorneys' fees, arising out of the breach on their respective parts
of any representations, warranties or agreements contained in this paragraph. 
The representations and obligations under this paragraph shall survive the
closing of the transactions contemplated in this Agreement (the "CLOSING") or,
if the Closing does not occur, the termination of this Agreement.

    7.   All notices hereunder shall be in writing and may be given either by
(a) federal express or other nationally recognized overnight courier or (b) hand
delivery, in each case to the Seller or Purchaser, as applicable, at the address
first set forth above with a copy in either case to Brown & Wood LLP, One World
Trade Center, New York, New York 10045.  Attn: David J. Weinberger, Esq. 
Notices shall be deemed given one day after posting, if given pursuant to (a)
above or upon delivery, if given pursuant to (b) above.

    8.   Time shall be of the essence with regard to all notices given
hereunder. 

                                       3


<PAGE>

    9.   All matters relating to the operation, construction or interpretation
of this Agreement shall be governed and determined by the internal laws of the
State of New York, without giving effect to the principles of conflicts of laws.

    10.  Unless specifically provided herein, no failure by any party to insist
upon the strict performance of any covenant, duty, agreement or condition of
this Agreement or to exercise any right or remedy upon a breach thereof shall
constitute a waiver of any such breach of any other covenant, agreement, term or
condition set forth herein.  Neither this Agreement nor any provision hereof may
be waived, modified, amended, discharged or terminated except by an instrument
signed by the party against whom the enforcement of such waiver, modification,
amendment, discharge or termination is sought, and then only to the extent set
forth in such instrument.  No waiver shall affect or alter the remainder of this
Agreement but each and every covenant, agreement, term and condition hereof
shall continue in full force and effect with respect to any other then existing
or subsequent breach.

    11.  This Agreement constitutes the entire agreement between the parties
hereto pertaining to the subject matter hereof and supersedes all prior and
contemporaneous agreements and understandings of the parties in connection
therewith.  No covenant, representation or condition not expressed in this
Agreement shall affect, or be effective to interpret, change or restrict, the
express provisions of this Agreement.

    12.  This Agreement may not be assigned, transferred or conveyed by
Purchaser to any person(s) or entity without the prior written consent of
Seller.

    13.  This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective heirs or successors and permitted assigns.

    14.  Exercise by Purchaser of the Option shall be subject to the approval
of a majority of the Independent Directors.  As used herein "Independent
Directors" shall mean the directors of SL Green Realty Corp. (the "COMPANY") who
are neither officers of the Company nor affiliated with Seller.

    15. No provision of this Agreement is intended, nor shall it be
interpreted, to provide or create any third party beneficiary rights or any
other rights of any kind in any customer, affiliate, stockholder, partner,
director, officer or employee of any party hereto or any other person or entity.

    16. If any provision of this Agreement, or the application thereof, is for
any reason held to any extent to be invalid or unenforceable, the remainder of
this Agreement and application of 

                                       4

<PAGE>

such provision to other persons or circumstances will be interpreted so as 
reasonably to effect the intent of the parties hereto.  The parties hereto 
further agree to replace such void or unenforceable provision of this 
Agreement with a valid and enforceable provision that will achieve, to the 
extent possible, the economic, business and other purposes of the void or 
unenforceable provision and to execute any amendment, consent or agreement 
deemed necessary or desirable by Purchaser to effect such replacement.

    17.  The parties hereto agree that irreparable damage would occur in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached.  It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any federal or state court located in New
York (as to which the parties agree to submit to jurisdiction for the purposes
of such action), this being in addition to any other remedy to which they are
entitled under this Agreement or otherwise at law or in equity.

    18.  The parties hereto each agree to do such other and further acts and
things, and to execute and deliver such instruments and documents (not creating
any obligations additional to those otherwise imposed by this Agreement) as
either may reasonably request from time to time, whether at, before or after the
Closing, to confirm or effectuate the provisions of this Agreement.

                             borrowing on a date other than the last day of the
                             applicable interest period, and (iii) restrictions
                             on the availability of LIBOR options when similar
                             deposits are not available to the Lenders.

INTEREST PAYMENTS:           On the first business day of each month or at the
                             end of each applicable interest period.
    
DEFEASANCE:                  Borrower shall have the right, from time to time
                             during the term of the Loan, to deposit cash into
                             a Collateral Account to be held by Lender, which
                             cash shall be pledged to Lender and which shall
                             constitute additional security for the Loan. 
                             Lender shall invest the sums in the Collateral
                             Account in U.S. Treasury Obligations having
                             maturities mutually acceptable to Borrower and
                             Lender (the cash, the U.S. Treasury Obligations
                             and the proceeds thereof, the "Treasury
                             Collateral").  Lender shall have a first perfected
                             lien and security interest in the Collateral
                             Account and the Treasury Collateral.  For so long
                             as the Treasury Collateral is held by Lender in
                             the Collateral Account, the interest rate on a
                             portion of the principal balance of the Loan equal
                             to the fair market value of the Treasury
                             Collateral (the "Defeased Amount") shall be a rate
                             per annum equal to 0.375%.  The Defeased Amount
                             shall change as the market value of the Treasury
                             Collateral changes. Provided no default shall have
                             occurred, all earnings paid on the Treasury
                             Collateral shall be applied first to pay the
                             interest due on the Defeased Amount and the
                             balance of the earnings shall be paid to Borrower. 
                             Upon request of Borrower, provided no default has
                             occurred, Borrower shall have the right to
                             withdraw the sums in the Collateral Account. 
                             Simultaneously with any such withdrawl, the
                             interest rate on the portion of the Loan that had
                             been defeased shall equal the Interest rate set
                             forth in this Term Sheet.

                             In the event that the Defeasance occurs on a day
                             other than the last day of an Interest Period,
                             Borrower shall also pay all

                             No defeasance hereunder shall in any way reduce
                             the principal balance of the Loan, and Borrower
                             shall not be entitled to any release of any other
                             collateral as a result of such defeasance.  The
                             Collateral Account and the Treasury Collateral are
                             additional and not substitute collateral for the
                             Loan.  No Non-Use Fee shall be due in connection
                             with any Defeased Portions.

                             liens of the mortgages contain a mortgage tax
                             endorsement satisfactory to Lender and that they
                             do NOT contain a pending disbursements clause.

COMMITMENT FEE:              0.50% of the Facility Amount, one-half of which
                             shall be paid at closing and the balance of which
                             shall be paid on the first anniversary of the
                             closing (or the termination of the Facility, if
                             earlier) (includes associated syndication fees). 
                             All amounts paid on account of the Commitment Fee
                             for the Interim Facility shall be credited to the
                             payment of the Commitment Fee hereunder.

NON-USE FEE:                 37.5 basis points per annum of the average daily

                             quarterly in arrears five business days after the

                             prepaid in whole or in part without premium or
                             penalty; provided that if prepayment is made on a
                             date other than the expiration of a LIBOR
                             contract, associated LIBOR breakage costs will
                             also be due.

AMORTIZATION:                Interest only during Facility term, subject to
                             maintenance of the Borrowing Base Covenants noted

                             then outstanding balance of the Facility shall be
                             due and payable.

law upon the death of a partner or stockholder of Borrower or any general

bargain, encumbrance, pledge, assignment, or transfer within the meaning of this
Section E.

         F.   INSURANCE AND CONDEMNATION.  

         (i)  INSURANCE.  Notwithstanding anything to the contrary in the
Notes, the Mortgages or the other Loan Documents:

              (a)  Partnership or LLC, as the case may be, will keep the
respective Properties insured against loss or damage by fire, flood and such
other hazards, risks and matters, including without limitation, business
interruption, rental loss, public liability, and boiler damage and liability, as
Lender may from time to time require in amounts required by Lender, and shall
pay the premiums for such insurance (the "Insurance Premiums") as the same
become due and payable.  All policies of insurance (the "Policies") shall be
issued by insurers acceptable to Lender and shall contain the standard New York
mortgagee non-contribution clause naming Lender as the person to which all
payments made by such insurance company shall be paid.  Partnership and LLC will
assign and deliver the respective Policies to Lender.  Not later than fifteen
(15) days prior to the expiration date of each of the Policies, Partnership and
LLC will deliver evidence satisfactory to Lender of the renewal of each of the
Policies.

              (b)  If any Property shall be damaged or destroyed, in whole or
in part, by fire or other casualty, Borrower shall give prompt notice thereof to
Lender.  Sums paid to Lender by any insurer may be retained and applied by
Lender, after deduction of Lender's reasonable costs and expenses of collection,
toward payment of the Debt in such priority and proportions as Lender in its
discretion shall deem proper or, at the discretion of Lender, either in whole or
in part, to Borrower for such purposes as Lender shall designate.  In the event
of any conflict, inconsistency or ambiguity between the provisions of this
paragraph F(i)(b) and the provisions of subsection 4 of Section 254 of the Real
Property Law of New York covering the insurance of buildings against loss by
fire, the provisions of this paragraph F shall control.

         (ii) CONDEMNATION.  Borrower shall promptly give Lender notice of the
actual or threatened commencement of any condemnation or eminent domain
proceeding and shall deliver to Lender copies of any and all papers served in
connection with such proceedings.  Notwithstanding any taking by any public or
quasi-public authority through 

                                        - 5 -


<PAGE>

eminent domain or otherwise (including but not limited to any transfer made in
lieu of or in anticipation of the exercise of such taking), Borrower shall
continue to pay the Debt at the time and in the manner provided for this
Agreement and the Debt shall not be reduced until any award or payment therefor
shall have been actually received and applied by Lender, after the deduction of
expenses of collection, to the reduction or discharge of the Debt.  Lender shall
not be limited to the interest paid on the award by the condemning authority but
shall be entitled to receive out of the award interest at the rate or rates
provided herein.  Lender may apply any such award or payment to the reduction or
discharge of the Debt whether or not then due and payable.  If any Property is
sold, through foreclosure or otherwise, prior to the receipt by Lender of such
award or payment, Lender shall have the right, whether or not a deficiency
judgment on the Note shall have been sought, recovered or denied, to receive
said award or payment, or a portion thereof sufficient to pay the Debt.

         G.   RECOURSE.  

         The Loan and each obligation of Borrower contained in the Notes, the
Mortgages and the other Loan Documents shall be fully recourse to Borrower;
however, no personal liability or personal deficiency judgment shall be asserted
or enforced against the REIT except as a result and to the extent of (i) fraud
or intentional misrepresentation by Borrower the REIT; (ii) Borrower's or the
REIT's misapplication or misappropriation of rent or other income derived from
the Properties; (iii) the misapplication or the misappropriation of insurance
proceeds or condemnation awards; or (iv) the occurrence of an Event of Default
under Section J(g) or (h) of this Agreement.  Notwithstanding the foregoing, the
agreement of Lender to not assert or enforce personal liability or a personal
deficiency judgment against the REIT SHALL BECOME NULL AND VOID and shall be of
no further force and effect in the event that there is any breach of Section E
or of Sections J(j) or (k) of this Agreement.

         H.   COMMITMENT FEE.  Simultaneously with the execution and delivery
of this Agreement, the Borrower and the REIT shall pay to Lender a commitment
fee equal to 0.50% of the Loan amount.   

         I.   SERVICING FEE.  Simultaneously with the execution and delivery of
this Agreement, Borrower and the REIT shall pay to Lender a servicing fee in
connection with the   administration of the Collateral Account equal to 0.02% of
the Loan Amount. 

         J.   EVENTS OF DEFAULT.  Each of the following events shall constitute
an "Event of Default":

         (a)  Borrower shall fail to pay (i) any principal of or interest on
the Loans when due (whether at stated maturity or by prepayment or otherwise) in

                                        - 6 -


<PAGE>

Agreement, shall prove to have been incorrect in any material respect on or as

purpose of effecting any of the foregoing;

ordering any of the foregoing;

PBGC under Section 4062 of ERISA and the currently payable obligations of the

or Plans subject to such event shall exceed ten percent (10%) of the Borrower's

and valuable consideration, the receipt of which is hereby acknowledged, the
Borrower hereby agrees with the Lender, as follows:

<PAGE>

              (b)  all cash, instruments, securities and funds deposited from

with respect to the Collateral, except as expressly provided herein.

         SECTION 4.     REPRESENTATION AND WARRANTY.  The Borrower represents
and warrants to the Lender that (i) this Agreement creates in favor of the
Lender an exclusive, perfected, first priority security interest in the
Collateral; and (ii) this Agreement has been duly executed and delivered by the
Borrower and constitutes a legal, valid and binding obligation of the Borrower,
enforceable in accordance with its terms, except as such enforcement may be
limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally and general equitable principles.

         SECTION 5.     COVENANTS.  The Borrower covenants and agrees with the
Lender that:

         (a)  The Borrower will not (i) sell, assign, transfer, exchange, or
otherwise dispose of, or grant any option with respect to, the Collateral, or
(ii) create, incur or permit to exist any lien, right of set-off or option in
favor of, or any claim of any Person with respect to, any of the Collateral, or
any interest therein, except for the security interest created by this
Agreement.

         (b)  The Borrower will maintain the security interest created by this
Agreement as an exclusive, first, perfected security interest in favor of the
Lender and defend the right, title and interest of the Lender in and to the
Collateral against the claims and demands of all Persons whomsoever. At any time
and from time to time, upon the request of the Lender, and at the sole expense
of the Borrower, the Borrower will promptly and duly execute and deliver such
further instruments and documents and take such further actions as the Lender
may request for the purposes of obtaining or preserving the full benefits of
this Agreement and of the rights and powers herein granted, including, without
limitation, the filing of Financing Statements under the Uniform Commercial
Code.

         SECTION 6.     APPLICATION AND INVESTMENT OF COLLATERAL.

         (a)  On the date hereof, Borrower shall deposit the sum of
$_____________ 

                                          3


<PAGE>

in the Collateral Account, and such sum shall be invested in United States
Treasury securities having a term approximately equal to the term of the Loan. 
Borrower shall make additional deposits  as may be required pursuant to Section
3(a) of  this Agreement.   All investments shall be made in the name of the
Lender or a nominee of the Lender and in a manner, determined by the Lender, in
its sole discretion, that preserves the Lender's exclusive, perfected, first
priority security interest in such investments. The Lender shall use reasonable
care in the custody and safekeeping of any such investments.

         (b)  The Lender shall have no responsibility to the Borrower for any
loss or liability arising in respect of any investments of the Collateral
(including, without limitation, as a result of the liquidation thereof), except,
to the extent that such loss or liability arises from the Lender's gross
negligence or willful misconduct.

         (c)  The Borrower will pay or reimburse the Lender for any and all
costs, expenses and liabilities of the Lender incurred in connection with this
Agreement, the maintenance and operation of the Collateral Account and the
investment of the Collateral, including, without limitation, any investment,
brokerage or placement commissions and fees incurred by the Lender in connection
with the investment or reinvestment of Collateral, and any investment charges or
other fees of the Lender in connection with maintenance of the Collateral
Account and any loss or expense incurred by Lender in connection with the
liquidation of any investment or reinvestment of the Collateral, including any
decline in the market value of the Collateral.  All such costs, expenses,
charges and fees shall constitute Secured Obligations.

         SECTION 7.     RELEASE OF COLLATERAL.  On the date on which the
Secured Obligations shall have been paid in full, the Lender shall release to
the Borrower or such other Person as the  Borrower may instruct all cash and
investments then held by the Lender in the Collateral Account, PROVIDED that if

<PAGE>

have delivered to Lender:

         (a)  all necessary documents to amend and restate the Note to reflect
that the principal balance of the Note has been defeased (the "Defeased Note"). 
(1) The Defeased Note shall be in a principal amount equal to the Defeasance
Amount, (2) be payable to the order of Lender, (3) be dated as of the date
hereof, (4) mature on the Maturity Date (the "Defeased Maturity Date") (5) be

         (c)  written confirmation from the Rating Agencies (as defined in the
Security Instrument) that such Defeasance will not result in a withdrawal,
downgrade or qualification of the then current ratings by the applicable Rating
Agencies of the Securities (as defined in the Security Instrument) and otherwise

required by the Rating Agencies, Borrower shall, at Borrower's expense (the cost
of which shall be subject to Lender's prior approval, which approval shall not
be unreasonably withheld), also deliver or cause to be delivered a
non-consolidation opinion with respect to the Defeasance Obligor (hereinafter
defined) in form and substance satisfactory to Lender and the Rating Agencies;

         (d)  a certificate of Borrower's independent certified public
accountant certifying that the Defeasance Collateral generates monthly amounts
equal to or greater than each monthly installment of principal and interest
required to be paid under the Defeased Note through and including the Maturity
Date and payments due thereon; and 

         (e)  Borrower shall deliver such other certificates, documents or
instruments as Lender may reasonably request or that the Rating Agencies may
require in connection with the Defeasance.  

         In connection with any Defeasance hereunder, Lender shall, or if any
Securities have been issued in connection with a securitization, Lender may, at
its option, and if it elects not to, [Lehman Brothers Realty Corporation] shall,
in each instance at Borrower's expense, establish or designate a successor
entity, which shall be a Single Purpose Entity (hereinafter defined) (the
"Defeasance Obligor") and Borrower shall transfer and assign all obligations,
rights and duties under and to the Defeased Note together with the 

                                         -5-


<PAGE>

pledged Defeasance Collateral to such Defeasance Obligor.  Such Defeasance
Obligor shall assume the obligations under the Defeased Note and any security
agreement executed in connection with the Defeasance or the Defeasance
Collateral delivered in connection therewith (the "Defeasance Security
Agreement"), and Borrower shall be relieved of its obligations under such
documents.

         Each of the obligations of the United States of America that is part
of the Defeasance Collateral shall be duly endorsed by the holder thereof as
directed by Lender or accompanied by a written instrument of transfer in form
and substance wholly satisfactory to Lender (including, without limitation, such
instruments as may be required by the depository institution holding such
securities or by the issuer thereof, as the case may be, to effectuate
book-entry transfers and pledges through the book-entry facilities of such
institution) in order to perfect upon the delivery of the Defeasance Collateral
the first priority security interest therein in favor of the Lender in
conformity with all applicable state and federal laws governing the granting of
such security interests.   Borrower shall authorize and direct that the payments
received from such obligations shall be made directly to Lender or Lender's
designee and applied to satisfy the obligations of Borrower under the Defeased
Note.  Borrower shall execute and deliver a Defeasance Security Agreement in
form and substance reasonably satisfactory to Lender creating a first priority
lien on the Defeasance Collateral delivered in connection with the Defeasance
and the Obligations purchased with the Defeasance Collateral.

         The Defeasance Collateral shall generate payments on or prior to, but
as close as possible to, the Business Day prior to each successive scheduled
payment date after the Defeasance Date upon which payments are required under
this Note and the Defeased Note, including the amount of accrued interest
together with the outstanding principal amount hereunder which would be due on
the Maturity Date (the "Scheduled Defeasance Payments").

         Notwithstanding any release of the Security Instrument granted
pursuant to this Article 5 or any Defeasance hereunder, Borrower shall and
hereby agrees to continue to be bound by and obligated under Articles 5, 7, and
15 and Sections 3.1, 7.4, 11.2, 11.10, 13.1, 13.4 and 14.2 of the Security
Instrument; provided however that all references therein to "Property" or
"Personal Property" shall be deemed to refer only to the Defeasance Collateral
delivered to Lender.

         All Defeasance Collateral shall be used and applied first to defease a
portion of this Note, together with such amount that is necessary for the
payment of all interest due and to become due with respect to such portion of
this Note.  Upon any release of the Security Instrument pursuant to this Section
5, the Defeasance Collateral delivered in connection therewith shall constitute
Collateral which shall secure the Obligations.

         Any revenue, documentary stamp or intangible taxes or any other tax or
charge due in connection with the creation of the Defeased Note, the
modification of this Note, or otherwise required to accomplish the Defeasance
shall be paid by Maker

with respect to Defeasance Collateral delivered to Lender, the aggregate amount

                                ARTICLE 6:  PREPAYMENT

         The principal balance of this Note may not be prepaid in whole or in
part prior to the Maturity Date.

         If a Default Prepayment (hereinafter defined) occurs, Borrower shall
pay to Lender the entire Debt, including, without limitation, a prepayment
consideration (the "Prepayment Consideration") in an amount equal to Yield
Maintenance (hereinafter defined). 

         The term "Default Prepayment" as used herein shall mean a prepayment
of the principal amount of this Note made during the continuance of any Event of
Default or after an acceleration of the Maturity Date under any circumstances,
including, without limitation, a prepayment occurring in connection with
reinstatement of the Security Instrument provided by statute under foreclosure
proceedings or exercise of a power of sale, any statutory right of redemption
exercised by Borrower or any other party having a statutory right to redeem or
prevent foreclosure, any sale in foreclosure or under exercise of a power of
sale or otherwise.

         The term "Yield Maintenance" as used herein shall mean an amount equal
to the greater of (A) one percent (1%) of the principal balance of this Note
outstanding on the date on which prepayment is to be made (the "Prepayment
Date"), and (B) the present value as of the Prepayment Date of the Calculated
Payments (hereinafter defined) from the Prepayment Date through the Maturity
Date determined by discounting each of such payments from the date of its
scheduled payment at the Discount Rate (hereinafter defined).

         The term "Calculated Payments as used herein" shall mean monthly
payments of interest only which would be due based on the principal amount
outstanding on the Prepayment Date and which would be outstanding each month
assuming the scheduled amortization, as the case may be, and assuming an
interest rate per annum equal to the difference (if such difference is greater
than zero) between (i) the Fixed Rate minus (ii) the Treasury Rate.  The
"Discount Rate" is the rate which, when compounded monthly, is equivalent to the
Treasury Rate when compounded semi-annually.  The "Treasury Rate" means the
yield calculated by the linear interpolation of the yields, as reported in the
Federal Reserve Statistical Release H.15-Selected Interest Rates under the
heading U.S. Government Securities/Treasury constant maturities for the week
ending prior to the Prepayment Date, of the U.S. Treasury constant maturities
with maturity dates (one longer and one shorter) most 

                                         -8-


<PAGE>

nearly approximating the Maturity Date.  In the event Release H.15 is no longer
published, Lender shall select a comparable publication to determine the
Prepayment Treasury Rate.  Lender shall notify Borrower of the amount and the
basis of determination of the required Prepayment Consideration (including a
detailed calculation of the same) which shall be conclusive and binding on
Borrower absent manifest error.  

         Lender shall notify Borrower of the amount and the basis of
determination of the required Prepayment Consideration and each component
thereof (including a detailed calculation of the same) which shall be conclusive
and binding on Borrower absent manifest error.  

         Notwithstanding anything herein to the contrary, provided no Event of
Default exists, no Prepayment Consideration shall be due in connection with (i)
a complete or partial prepayment resulting from the application of Net Proceeds
(as defined in the Security Instrument) pursuant to Section 4.4 of the Security
Instrument (a "Mandatory Prepayment") or (ii) a Defeasance pursuant to  Section
5 above.  Notwithstanding anything herein to the contrary, if any Mandatory
Prepayment occurs on a date that is not a Payment Date, the amount due from
Borrower on the date of such Mandatory Prepayment shall include a payment (a
"Shortfall Interest Payment") equal to (a) the amount of all accrued and unpaid
interest on the outstanding principal balance of this Note as of the date of
such Mandatory Prepayment, plus (b) the interest which would have accrued on the
amount of the Mandatory Prepayment from the date of such Mandatory Prepayment to
the last day preceding the next Payment Date.  On the Payment Date following any
such Mandatory Prepayment, Borrower shall receive a credit against the payment
then due equal to the amount of such Shortfall Interest Payment. 


                                 ARTICLE 7:  SECURITY

located in New York County, State of New York, and other property, as more
particularly described therein (collectively, the "Initial Property"; the
Initial Property, the Substitute Property and each Additional Property (as
defined in the Loan Agreement), as the case may be, shall be referred to herein
as the "Property") and intended to be duly recorded in said County and (ii) from
and after the substitution of the Substitution Property pursuant to Section 4 of
the Loan Agreement or the substitution or addition of the Additional Properties
pursuant to Section 5 of the Loan Agreement, the Spread Mortgage (as defined in
the Loan Agreement).  The term "Other Security Documents" as used in this Note
shall mean all and any of the documents other than this Note or the Security
Instrument now or hereafter executed by Borrower and/or others and by or in
favor of Lender, which wholly or partially secure or guarantee payment of this 

                                         -9-


<PAGE>

Note including, but not limited to, that certain Loan Agreement dated the date
hereof between Borrower and Lender.  Whenever used, the singular number shall
include the plural, the plural number shall include the singular, and the words
"Lender" and "Borrower" shall include their respective successors, assigns,
heirs, executors and administrators.

Instrument and the Other Security Documents are hereby made part of this Note to

                              ARTICLE 8:  SAVINGS CLAUSE

    This Note is subject to the express condition that at no time shall
Borrower be obligated or required to pay interest on the principal balance due
hereunder at a rate which could subject Lender to either civil or criminal
liability as a result of being in excess of the maximum interest rate which
Borrower is permitted by applicable law to contract or agree to pay.  If by the
terms of this Note, Borrower is at any time required or obligated to pay
interest on the principal balance due hereunder at a rate in excess of such
maximum rate, the Applicable Interest Rate or the Default Rate, as the case may
be, shall be deemed to be immediately reduced to such maximum rate and all
previous payments in excess of the maximum rate shall be deemed to have been
payments in reduction of principal and not on account of the interest due
hereunder.  All sums paid or agreed to be paid to Lender for the use,
forbearance, or detention of the Debt, shall, to the extent permitted by
applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of the Note until payment in full so that the rate or amount of
interest on account of the Debt does not exceed the maximum lawful rate of
interest from time to time in effect and applicable to the Debt for so long as
the Debt is outstanding.


                               ARTICLE 9:  LATE CHARGE

    If any sum payable under this Note is not paid prior to the fifth (5th) day
after the date on which it is due, Borrower shall pay to Lender upon demand an
amount equal to the lesser of five percent (5%) of the unpaid sum or the maximum
amount permitted by applicable law to defray the expenses incurred by Lender in
handling and processing the delinquent payment and to compensate Lender for the
loss of the use of the delinquent payment and the amount shall be secured by the
Security Instrument and the Other Security Documents.


                             ARTICLE 10:  NO ORAL CHANGE

    This Note may not be modified, amended, waived, extended, changed,
discharged or terminated orally or by any act or failure to act on the part of
Borrower or Lender, but only

modification, amendment, waiver, extension, change, discharge or termination is
sought.

    Borrower and all others who may become liable for the payment of all or any
part of the Debt do hereby severally waive presentment and demand for payment,
notice of dishonor, protest and notice of protest and non-payment and all other
notices of any kind.  No release of any security for the Debt or extension of
time for payment of this Note or any installment hereof, and no alteration,
amendment or waiver of any provision of this Note, the Security Instrument or
the Other Security Documents made by agreement between Lender or any other
person or party shall release, modify, amend, waive, extend, change, discharge,
terminate or affect the liability of Borrower, and any other person or entity
who may become liable for the payment of all or any part of the Debt, under this
Note, the Security Instrument or the Other Security Documents.  No notice to or
demand on Borrower shall be deemed to be a waiver of the obligation of Borrower
or of the right of Lender to take further action without further notice or
demand as provided for in this Note, the Security Instrument or the Other
Security Documents.  If Borrower is a partnership, the agreements herein
contained shall remain in force and applicable, notwithstanding any changes in
the individuals comprising the partnership, and the term "Borrower," as used
herein, shall include any alternate or successor partnership, but any
predecessor partnership and their partners shall not thereby be released from
any liability.  If Borrower is a corporation, the agreements contained herein
shall remain in full force and applicable notwithstanding any changes in the
shareholders comprising, or the officers and directors relating to, the
corporation, and the term "Borrower" as used herein, shall include any
alternative or successor corporation, but any predecessor corporation shall not
be relieved of liability hereunder.  (Nothing in the foregoing sentence shall be
construed as a consent to, or a waiver of, any prohibition or restriction on
transfers of interests in such partnership which may be set forth in the
Security Instrument or any Other Security Document.)


                                 ARTICLE 13: TRANSFER

    Upon the transfer of this Note, Borrower hereby waiving notice of any such
transfer, Lender may deliver all the collateral mortgaged, granted, pledged or
assigned pursuant to the Security Instrument and the Other Security Documents,
or any part thereof, to the transferee who shall thereupon become vested with
all the rights herein or under applicable law given to 

                                         -11-


<PAGE>

Lender with respect thereto, and Lender shall thereafter forever be relieved and
fully discharged from any liability or responsibility in the matter; but Lender

the collateral not so transferred.


                         ARTICLE 14:  WAIVER OF TRIAL BY JURY

    BORROWER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT

TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN EVIDENCED BY THIS
NOTE, THE APPLICATION FOR THE LOAN EVIDENCED BY THIS NOTE, THIS NOTE, THE
SECURITY INSTRUMENT OR THE OTHER SECURITY DOCUMENTS OR ANY ACTS OR OMISSIONS OF
LENDER, ITS OFFICERS, EMPLOYEES, DIRECTORS OR AGENTS IN CONNECTION THEREWITH.

Note or the Security Instrument by any action or proceeding wherein a money
judgment shall be sought against Borrower, except that Lender may bring a
foreclosure action, action for specific performance or other appropriate action
or proceeding to enable Lender to enforce and realize upon this Note, the
Security Instrument, the Other Security Documents, and the interest in the

right of Lender to obtain a deficiency judgment in any action or proceeding in
order to preserve its rights and remedies, including, without limitation,

    (b)  Notwithstanding the provisions of this Section 14 to the contrary,

pursuant to the terms of the Security Instrument), charges for labor or
materials or other charges that can create liens on the Property; (vi)
Borrower's failure to maintain, repair or restore the Property in accordance
with the Security Instrument and the Other Security Documents; (vii) Borrower's
failure to return or to reimburse Lender for all Personal Property (as defined

principal, affiliate or general partner thereof or by any Indemnitor or
Guarantor; (ix) any fees or commissions paid by Borrower to any principal,
affiliate or general partner of Borrower, Indemnitor or Guarantor in violation
of the terms of this Note, the Security Instrument or the Other Security
Documents; (x) dividends or distributions made by Borrower at any time during
the twelve (12) month period prior to a Default or Event of Default; (xi)
Borrower's failure to comply with the provisions of Sections 4.2, 7.1, 12.1 and
12.2 of the Security Instrument; or (xii) impair the right of Lender to obtain a
deficiency judgment in any action or proceeding in order to preserve its rights
and remedies, including, without limitation, an action against Borrower under
the Note, a foreclosure, non-judicial foreclosure, or the exercise of a power of
sale, under the Additional Security Instruments; however, Lender agrees that it
shall not enforce such deficiency judgment against any assets of Borrower other
than the Additional Properties or in the exercise of its rights and remedies
under the Additional Security Instruments.

    (c)  Notwithstanding the foregoing, the agreement of Lender not to pursue
recourse liability as set forth in Subsection (a) above SHALL BECOME NULL AND
VOID and shall be of no further force and effect in the event of Borrower's
default under Sections 3.11 and

Lender may have under Section 506(a), 506(b), 1111(b) or any other provision of
the U.S. Bankruptcy Code to file a claim for the full amount of the indebtedness
secured by the Security Instrument or to require that all collateral shall

         of sale, or delivery of a deed in lieu of foreclosure of the Security
         Instrument.

         this Agreement shall become immediately due and payable on demand and,
         if not paid within thirty (30) days of such demand therefor, shall
         bear interest at a per annum rate equal to the Default Rate.

    xi.       WAIVERS.  (a) Indemnitor hereby waives (i) any right or claim of
         right to cause a marshalling of Indemnitor's assets or to cause

         subrogation which Indemnitor may have, provided that the indemnity
         provided for hereunder shall neither be contingent upon the existence
         of any such rights of subrogation nor subject to any claims or
         defenses whatsoever which may be asserted in connection with the
         enforcement or attempted enforcement of such subrogation rights
         including, without limitation, any claim that such subrogation rights
         were abrogated by any acts of Indemnitee or other Indemnified Parties;
         (iii) the right to assert a counterclaim, other than a mandatory or
         compulsory counterclaim, in any action or proceeding brought against
         or by Indemnitee or other Indemnified Parties; (iv) notice of
         acceptance hereof and of any action taken or omitted in reliance
         hereon; (v) presentment for payment, demand of payment, protest or
         notice of nonpayment or failure to perform or observe, or other proof,
         or notice or demand; and (vi) all homestead exemption rights against
         the obligations hereunder and the benefits of any statutes of
         limitations or repose.  Notwithstanding anything to the contrary
         contained herein, Indemnitor hereby agrees to postpone the exercise of
         any rights of subrogation with respect to any collateral securing the
         Loan until the Loan shall have been paid in full.

    (b)  INDEMNITOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM, WHETHER IN
CONTRACT, TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN
EVIDENCED BY THE NOTE, THE APPLICATION FOR THE LOAN EVIDENCED BY THE NOTE, THE
LOAN AGREEMENT, THE SECURITY INSTRUMENT, THIS AGREEMENT OR THE OTHER SECURITY

         compensation from such persons responsible for the presence of any
         Hazardous Substances at, in, on, under or near the Property or
         otherwise obligated by law to bear the cost.  Indemnified Parties

         or hereafter in such claims.

    xiii      INDEMNITOR'S REPRESENTATIONS AND WARRANTIES.  Indemnitor

    execution of, and compliance with, this Agreement is in the ordinary course
    of business of that Indemnitor and will not result in the breach of any
    term or provision of the charter, by-laws, partnership or trust agreement,
    or other governing instrument of that Indemnitor or result in the breach of
    any term or provision of, or conflict with or constitute a default under or

    material adverse change in the business, operations, financial condition,
    properties or assets of Indemnitor, or in any material impairment of the
    right or ability of Indemnitor to carry on its business substantially as
    now conducted, or in any material liability on the part of Indemnitor, or
    which would draw into question the validity of this Agreement or of any
    action taken or to be taken in connection with the obligations of
    Indemnitor contemplated herein, or which would be likely to impair
    materially the ability of Indemnitor to perform under the terms of this
    Agreement;

    believe, that it cannot perform each and every covenant contained in this

and direct the lessees named in the Leases or any other or future lessees or
occupants of the Property and all Lease Guarantors to pay over to Lender or to
such other party as Lender directs all Rents and all sums due under any Lease
Guaranties upon receipt from Lender of written notice to the effect that Lender
is then the holder of the Security Instrument and that a Default (defined below)
exists, and to continue so to do until otherwise notified by Lender.

          Section 2.3    INCORPORATION BY REFERENCE.  All representations,
warranties, covenants, conditions and agreements contained in the Security
Instrument as same may be modified, renewed, substituted or extended are hereby
made a part of this Assignment to the same extent and with the same force as if

          Section 3.1    REMEDIES OF LENDER.  Upon or at any time after the
occurrence of a default under this Assignment or an Event of Default (as defined

In addition, Lender may, at its option, without waiving such Default, without
notice and without regard to the adequacy of the security for the Debt, either
in person or by agent, nominee or attorney, with or without bringing any action
or proceeding, or by a receiver appointed by a court, dispossess Borrower and
its agents and servants from the Property, without liability for trespass,
damages or otherwise and exclude Borrower and its agents or servants wholly
therefrom, and take possession of the Property and all books, records and
accounts relating thereto and have, hold, manage, lease and operate the Property
on such terms and for such period of time as Lender may deem proper and either
with or without taking possession of the Property in its own name, demand, sue
for or otherwise collect and receive all Rents and sums due under all Lease
Guaranties, including those past due and unpaid with full power to make from
time to time all alterations, renovations, repairs or replacements thereto or
thereof as may seem proper to Lender and may apply the Rents and sums received
pursuant to any Lease Guaranties to the payment of the following in such order
and proportion as Lender in its sole discretion may determine, any law, custom
or use to the contrary notwithstanding:  (a) all expenses of managing and
securing the Property, including, without being limited thereto, the salaries,
fees and wages of a managing agent and such other employees or agents as Lender
may deem necessary or desirable and all expenses of operating and maintaining
the Property, including, without being limited thereto, all taxes, charges,
claims, assessments, water charges, sewer rents and any other liens, and
premiums for all insurance which Lender may deem necessary or desirable, and the
cost of all alterations, renovations, repairs or replacements, and all expenses
incident to taking and retaining possession of the Property; and (b) the Debt,
together with all costs and reasonable attorneys' fees.  In addition, upon the
occurrence of a Default, Lender, at its option, may (1) complete any
construction on the Property in such manner and form as Lender deems advisable,
(2) exercise all rights and powers of Borrower, including, without limitation,
the right to negotiate, execute, cancel, enforce or modify Leases, obtain and
evict tenants, and demand, sue for, collect and receive all Rents from the
Property and all sums due under any Lease Guaranties, (3) either require
Borrower to pay monthly in advance to Lender, or any receiver appointed to
collect the Rents, the fair and reasonable rental value for the use and
occupancy of such part of the Property as may be in possession of Borrower or
(4) require Borrower to vacate and surrender possession of the Property to
Lender or to such receiver and, in default thereof, Borrower may be evicted by
summary proceedings or otherwise.  

          Section 3.2    OTHER REMEDIES.  Nothing contained in this Assignment
and no act done or omitted by Lender pursuant to the power and rights granted to
Lender hereunder shall be deemed to be a waiver by Lender of its rights and
remedies under the

<PAGE>

Note, the Security Instrument, or the Other Security Documents and this
Assignment is made and accepted without prejudice to any of the rights and
remedies possessed by Lender under the terms thereof.  The right of Lender to
collect the Debt and to enforce any other security therefor held by it may be
exercised by Lender either prior to, simultaneously with, or subsequent to any
action taken by it hereunder.  Borrower hereby absolutely, unconditionally and
irrevocably waives any and all rights to assert any setoff, counterclaim or
crossclaim of any nature whatsoever with respect to the obligations of Borrower
under this Assignment, the Note, the Security Instrument, the Other Security
Documents or otherwise with respect to the loan secured hereby in any action or
proceeding brought by Lender to collect same, or any portion thereof, or to
enforce and realize upon the lien and security interest created by this
Assignment, the Note, the Security Instrument, or any of the Other Security
Documents (provided, however, that the foregoing shall not be deemed a waiver of
Borrower's right to assert any compulsory counterclaim if such counterclaim is
compelled under local law or rule of procedure, nor shall the foregoing be
deemed a waiver of Borrower's right to assert any claim which would constitute a
defense, setoff, counterclaim or crossclaim of any nature whatsoever against
Lender in any separate action or proceeding).

          Section 3.3    OTHER SECURITY.  Lender may take or release other
security for the payment of the Debt, may release any party primarily or
secondarily liable therefor and may apply any other security held by it to the
reduction or satisfaction of the Debt without prejudice to any of its rights
under this Assignment.

          Section 3.4    NON-WAIVER.  The exercise by Lender of the option
granted it in Section 3.1 of this Assignment and the collection of the Rents and
sums due under the Lease Guaranties and the application thereof as herein
provided shall not be considered a waiver of any default by Borrower under the
Note, the Security Instrument, the Leases, this Assignment or the Other Security
Documents.  The failure of Lender to insist upon strict performance of any term
hereof shall not be deemed to be a waiver of any term of this Assignment. 
Borrower shall not be relieved of Borrower's obligations hereunder by reason of
(a) the failure of Lender to comply with any request of Borrower or any other
party to take any action to enforce any of the provisions hereof or of the
Security Instrument, the Note, or the Other Security Documents, (b) the release
regardless of consideration, of the whole or any part of the Property, or (c)
any agreement or stipulation by Lender extending the time of payment or
otherwise modifying or supplementing the terms of this Assignment, the Note, the
Security Instrument or the Other Security Documents.  Lender may resort for the
payment of the Debt to any other security held by Lender in such order and
manner as Lender, in its discretion, may elect.  Lender may take any action to
recover the Debt, or any portion thereof, or to enforce any covenant hereof
without prejudice to the right of Lender thereafter to enforce its rights under
this Assignment.  The rights of Lender under this Assignment shall be separate,
distinct and cumulative and none shall be given effect to the exclusion of the
others.  No act of Lender shall be construed as an election to proceed under any
one provision herein to the exclusion of any other provision.

          Section 3.5    BANKRUPTCY.  (a) Upon or at any time after the
occurrence of a 

                                        - 5 -


<PAGE>

Default, Lender shall have the right to proceed in its own name or in the name
of Borrower in respect of any claim, suit, action or proceeding relating to the
rejection of any Lease, including, without limitation, the right to file and
prosecute, to the exclusion of Borrower, any proofs of claim, complaints,
motions, applications, notices and other documents, in any case in respect of
the lessee under such Lease under the Bankruptcy Code.  

               (b) If there shall be filed by or against Borrower a petition
under the Bankruptcy Code, and Borrower, as lessor under any Lease, shall
determine to reject such Lease pursuant to Section 365(a) of the Bankruptcy
Code, then Borrower shall give Lender not less than ten (10) days' prior notice
of the date on which Borrower shall apply to the bankruptcy court for authority
to reject the Lease.  Lender shall have the right, but not the obligation, to
serve upon Borrower within such ten-day period a notice stating that (i) Lender
demands that Borrower assume and assign the Lease to Lender pursuant to Section
365 of the Bankruptcy Code and (ii) Lender covenants to cure or provide adequate
assurance of future performance under the Lease.  If Lender serves upon Borrower
the notice described in the preceding sentence, Borrower shall not seek to
reject the Lease and shall comply with the demand provided for in clause (i) of
the preceding sentence within thirty (30) days after the notice shall have been
given, subject to the performance by Lender of the covenant provided for in
clause (ii) of the preceding sentence.

                     ARTICLE 4 - NO LIABILITY, FURTHER ASSURANCES

          Section 4.1    NO LIABILITY OF LENDER.  This Assignment shall not be
construed to bind Lender to the performance of any of the covenants, conditions
or provisions contained in any Lease or Lease Guaranty or otherwise impose any
obligation upon Lender.  Lender shall not be liable for any loss sustained by
Borrower resulting from Lender's failure to let the Property after a Default or
from any other act or omission of Lender in managing the Property after a
Default unless such loss is caused by the willful misconduct and bad faith of
Lender.  Lender shall not be obligated to perform or discharge any obligation,
duty or liability under the Leases or any Lease Guaranties or under or by reason
of this Assignment and Borrower shall, and hereby agrees, to indemnify Lender
for, and to hold Lender harmless from, any and all liability, loss or damage
which may or might be incurred under the Leases, any Lease Guaranties or under
or by reason of this Assignment and from any and all claims and demands
whatsoever, including the defense of any such claims or demands which may be
asserted against Lender by reason of any alleged obligations and undertakings on
its part to perform or discharge any of the terms, covenants or agreements
contained in the Leases or any Lease Guaranties.  Should Lender incur any such
liability, the amount thereof, including costs, expenses and reasonable
attorneys' fees, shall be secured by this Assignment and by the Security
Instrument, and the Other Security Documents and Borrower shall reimburse Lender
therefor immediately upon demand and upon the failure of Borrower so to do
Lender may, at its option, declare all sums secured by this Assignment and by
the Security Instrument, and the Other Security Documents immediately due and
payable.  This Assignment shall not operate to place any obligation or liability
for the control, care, management or repair of the Property upon Lender, nor for
the 

                                        - 6 -

carrying out of any of the terms and conditions of the Leases or any Lease
Guaranties; nor shall it operate to make Lender responsible or liable for any
waste committed on the Property by the tenants or any other parties, or for any
dangerous or defective condition of the Property, including without limitation
the presence of any Hazardous Substances (as defined in the Security
Instrument), or for any negligence in the management, upkeep, repair or control
of the Property resulting in loss or injury or death to any tenant, licensee,
employee or stranger.

          Section 4.2    NO MORTGAGEE IN POSSESSION.  Nothing herein contained
shall be construed as constituting Lender a "mortgagee in possession" in the
absence of the taking of actual possession of the Property by Lender.  In the
exercise of the powers herein granted Lender, no liability shall be asserted or
enforced against Lender, all such liability being expressly waived and released
by Borrower.

          Section 4.3    FURTHER ASSURANCES.  Borrower will, at the cost of
Borrower, and without expense to Lender, do, execute, acknowledge and deliver
all and every such further acts, conveyances, assignments, notices of
assignments, transfers and assurances as Lender shall, from time to time,
require for the better assuring, conveying, assigning, transferring and
confirming unto Lender the property and rights hereby assigned or intended now
or hereafter so to be, or which Borrower may be or may hereafter become bound to
convey or assign to Lender, or for carrying out the intention or facilitating
the performance of the terms of this Assignment or for filing, registering or
recording this Assignment and, on demand, will execute and deliver and hereby
authorizes Lender to execute in the name of Borrower to the extent Lender may

hereof may not be modified, amended, waived, extended, changed, discharged or

assigned with respect to the Property, (b) neither Agent nor Borrower is in

notice for the purpose of terminating the Management Agreement with respect to

provisions of the Management Agreement without the prior written consent of

responsibility for the management of the Property to a management company
selected by Lender in Lender's sole and absolute discretion.

         7.   LENDER'S RIGHT TO REPLACE AGENT.  In addition to the foregoing,
in the event the Agent shall become insolvent, or a Default (as defined in the
Security Instrument) or Event of Default shall occur and be continuing, then
Lender, at its option, may require Borrower to engage a bona-fide, independent
third party management agent approved by Lender in its sole discretion (the "New
Agent") to manage the Property.  The New Agent shall be engaged by Borrower
pursuant to a written management agreement that complies with the terms hereof
and is otherwise satisfactory to Lender in all respects.

         8.   RECEIPT OF MANAGEMENT FEES.  Borrower and Agent hereby agree that
Agent shall not be entitled to receive any Management Fees or other fee,
commission or other amount payable to Agent under the Management Agreement for
and during any period of time that any Event of Default has occurred and is
continuing; provided, however, that Agent shall not be obligated to return or
refund to Lender any Management Fee or other fee, commission or other amount
already received by Agent prior to the occurrence of the Event of Default, and
to which Agent was entitled under this Assignment.

         9.  CONSENT AND AGREEMENT BY AGENT.  Agent hereby acknowledges and
consents to this Assignment and agrees that Agent will act in conformity with
the provisions of this Assignment and Lender's rights hereunder or otherwise
related to the Management Agreement.  In the event that the responsibility for
the management of the Property is transferred from Agent in accordance with the
provisions hereof, Agent shall, and hereby agrees to, fully cooperate in
transferring its responsibility to a new management company and effectuate such
transfer no later than thirty (30) days from the date the Management Agreement
is terminated.  Further, Agent hereby agrees (a) not to contest or impede the
exercise by Lender of any right it has under or in connection with this
Assignment; and (b) that it shall, in the manner provided for in this
Assignment, give at least thirty (30) days prior written notice to Lender of its
intention to terminate the Management Agreement or otherwise discontinue its
management of the Property.

          10. NO SUBCONTRACTING.  Notwithstanding anything in the Management
Agreement to the contrary, Agent shall not sub-contract any or all of its
management responsibilities under the Management Agreement to a third party or
an affiliate without the prior written consent of Lender, such consent not to be
unreasonably withheld.

         11.  LENDER'S AGREEMENT.  So long as Borrower is not in default
(beyond any applicable grace period) under this Assignment, the Note, the

         respecting or pertaining to the use, occupation, construction,
         management or operation of the Land and any part thereof and any
         Improvements or respecting any business or activity conducted on the
         Land and any part thereof and all right, title and interest of
         Borrower therein and thereunder, including, without limitation, the
         right, upon the happening of any default hereunder, to receive and
         collect any sums payable to Borrower thereunder; 

              (m)  TRADEMARKS.  All tradenames, trademarks, servicemarks,

         intangibles relating to or used in connection with the operation of

              (n)  OTHER RIGHTS.  Any and all other rights of Borrower in and
         to the items set forth in Subsections (a) through (m) above and all
         proceeds and products of any of the foregoing and all rights and
         privileges pertaining thereto.

         Section 1.2    ASSIGNMENT OF RENTS.  Borrower hereby absolutely and
unconditionally assigns to Lender Borrower's right, title and interest in and to
all current and future Leases and Rents; it being intended by Borrower that this
assignment constitutes a present, absolute assignment and not an assignment for
additional security only.  Nevertheless, subject to the terms of this Section
1.2, Section 3.7 and Section 4.5, Lender grants to Borrower a revocable license
to collect and receive the Rents.  Borrower shall hold the Rents, or a portion
thereof sufficient to discharge all current sums due on the Debt, for use in the
payment of such sums.

         Section 1.3    SECURITY AGREEMENT.  This Security Instrument is both a
real property mortgage and a "security agreement" within the meaning of the
Uniform Commercial Code.  The Property includes both real and personal property
and all other rights and interests, whether tangible or intangible in nature, of
Borrower in the Property.  By executing and delivering this Security Instrument,
Borrower hereby grants to Lender, as security for the Obligations (defined in
Section 2.3), a security interest in the Personal Property to the full extent
that the Personal Property may be subject to the Uniform Commercial Code.

         Section 1.4    PLEDGE OF MONIES HELD.  Borrower hereby pledges to
Lender any and all monies now or hereafter held by Lender, including, without
limitation, any sums deposited in the Escrow Fund (as defined in Section 3.5),
Net Proceeds (as defined in Section 4.4) and condemnation awards or payments
described in Section 3.6, as additional security for the Obligations until
expended or applied as provided in this Security Instrument.

                                 CONDITIONS TO GRANT

         TO HAVE AND TO HOLD the above granted and described Property with all
privileges and appurtenances thereunto belonging unto and to the use and benefit
of Lender,

and the heirs, successors and assigns of Lender, forever;


         PROVIDED, HOWEVER, these presents are upon the express condition that,
if Borrower shall well and truly pay to Lender the Debt at the time and in the
manner provided in the Note and this Security Instrument, shall well and truly
perform the Other Obligations as set forth in this Security Instrument and shall
well and truly abide by and comply with each and every covenant and condition
set forth herein and in the Note, these presents and the estate hereby granted
shall cease, terminate and be void.


                       ARTICLE 2 - DEBT AND OBLIGATIONS SECURED

         Section 2.1    DEBT.  This Security Instrument and the grants,
assignments and transfers made in Article 1 are given for the purpose of
securing the following, in such order of priority as Lender may determine in its
sole discretion (the "Debt"):

         (a)  the payment of the indebtedness evidenced by the Note in lawful
    money of the United States of America;

         (b)  the payment of interest, default interest, late charges and other
    sums, as provided in the Note, the Loan Agreement, this Security Instrument
    or the Other Security Documents (defined below); 

         (c)  Prepayment Consideration (as defined in the Note);

         (d)  the payment of all other moneys agreed or provided to be paid by
    Borrower in the Note, the Loan Agreement, this Security Instrument or the
    Other Security Documents;

         (e)  the payment of all sums advanced pursuant to this Security
    Instrument to protect and preserve the Property and the lien and the
    security interest created hereby; and

         (f)  the payment of all sums advanced and costs and expenses incurred
    by Lender in connection with the Debt or any part thereof, any renewal,
    extension, or change of or substitution for the Debt or any part thereof,
    or the acquisition or perfection of the security therefor, whether made or
    incurred at the request of Borrower or Lender.

         Section 2.2    OTHER OBLIGATIONS.  This Security Instrument and the
grants, assignments and transfers made in Article 1 are also given for the
purpose of securing the following (the "Other Obligations"):

         (a)  the performance of all other obligations of Borrower contained
    herein;

                                        - 7 -


<PAGE>

         (b)  the performance of each obligation of Borrower contained in any
    other agreement given by Borrower to Lender which is for the purpose of
    further securing the obligations secured hereby, and any amendments,
    modifications and changes thereto; and

         (c)  the performance of each obligation of Borrower contained in any
    renewal, extension, amendment, modification, consolidation, change of, or
    substitution or replacement for, all or any part of the Note, the Loan
    Agreement, this Security Instrument or the Other Security Documents.

         Section 2.3    DEBT AND OTHER OBLIGATIONS.  Borrower's obligations for
the payment of the Debt and the performance of the Other Obligations shall be
referred to collectively below as the "Obligations."

         Section 2.4    PAYMENTS.  Unless payments are made in the required
amount in immediately available funds at the place where the Note is payable,
remittances in payment of all or any part of the Debt shall not, regardless of
any receipt or credit issued therefor, constitute payment until the required
amount is actually received by Lender in funds immediately available at the
place where the Note is payable (or any other place as Lender, in Lender's sole
discretion, may have established by delivery of written notice thereof to
Borrower) and shall be made and accepted subject to the condition that any check
or draft may be handled for collection in accordance with the practice of the
collecting bank or banks.  Acceptance by Lender of any payment in an amount less
than the amount then due shall be deemed an acceptance on account only, and the
failure to pay the entire amount then due shall be and continue to be an Event
of Default (defined herein).


                            ARTICLE 3 - BORROWER COVENANTS

         Borrower covenants and agrees that:

         Section 3.1    PAYMENT OF DEBT.  Borrower will pay the Debt at the
time and in the manner provided in the Note and in this Security Instrument.

         Section 3.2    INCORPORATION BY REFERENCE.  All the covenants,
conditions and agreements contained in (a) the Loan Agreement, (b) the Note and
(c) all and any of the documents other than the Note, the Loan Agreement or this
Security Instrument now or hereafter executed by Borrower and/or others and by
or in favor of Lender, which wholly or partially secure or guaranty payment of
the Note, including without limitation each Loan Document (as defined in the
Loan Agreement) (the "Other Security Documents"), are hereby made a part of this
Security Instrument to the same extent and with the same force as if fully set
forth herein.

         Section 3.3    INSURANCE.

                                        - 8 -


<PAGE>

         (a)  Borrower shall obtain and maintain, or cause to be maintained,
insurance for Borrower and the Property providing at least the following
coverages:

         (i)     comprehensive all risk insurance on the Improvements and the
    Personal Property, including contingent liability from Operation of
    Building Laws, Demolition Costs and Increased Cost of Construction
    Endorsements, in each case (A) in an amount equal to 100% of the "Full
    Replacement Cost," which for purposes of this Security Instrument shall
    mean actual replacement value (exclusive of costs of excavations,
    foundations, underground utilities and footings) with a waiver of
    depreciation, but the amount shall in no event be less than the outstanding
    principal balance of the Note; (B) containing an agreed amount endorsement
    with respect to the Improvements and Personal Property waiving all
    co-insurance provisions; (C) providing for no deductible in excess of
    $50,000; and (D)  containing an "Ordinance or Law Coverage" or
    "Enforcement" endorsement if any of the Improvements or the use of the
    Property shall at any time constitute legal non-conforming structures or
    uses.  The Full Replacement Cost shall be redetermined from time to time
    (but not more frequently than once in any twelve (12) calendar months) at
    the request of Lender by an appraiser or contractor designated and paid by
    Borrower and approved by Lender, or by an engineer or appraiser in the
    regular employ of the insurer.  After the first appraisal, additional
    appraisals may be based on construction cost indices customarily employed
    in the trade.  No omission on the part of Lender to request any such
    ascertainment shall relieve Borrower of any of its obligations under this
    Subsection.  In addition, Borrower shall obtain (y) flood hazard insurance
    if any portion of the Improvements is currently or at any time in the
    future located in a federally designated "special flood hazard area", flood
    hazard insurance in an amount equal to the lesser of (a) the outstanding
    principal balance of the Note or (b) the maximum amount of such insurance
    available under the National Flood Insurance Act of 1968, the Flood
    Disaster Protection Act of 1973 or the National Flood Insurance Reform Act
    of 1994, as each may be amended or such greater amount as Lender shall
    require; or as otherwise required by Lender, and (z) earthquake insurance
    in amounts and in form and substance satisfactory to Lender in the event
    the Property is located in an area with a high degree of seismic activity,
    or as otherwise required by Lender, provided that the insurance pursuant to
    clauses (y) and (z) hereof shall be on terms consistent with the
    comprehensive all risk insurance policy required under this Subsection
    3.3(a)(i) except that the deductible on such insurance shall not be in
    excess of five percent (5%) of the appraised value of the Property;

         (ii)    commercial general liability insurance against claims for
    personal injury, bodily injury, death or property damage occurring upon, in
    or about the Property, such insurance (A) to be on the so-called
    "occurrence" form with a combined single limit of not less than $1,000,000;
    (B) to continue at not less than the aforesaid limit until required to be
    changed by Lender in writing by reason of changed economic conditions
    making such protection inadequate; and (C) to cover at least the following
    hazards: (1) premises and operations; (2) products and completed 

                                        - 9 -


<PAGE>

    operations on an "if any" basis; (3) independent contractors; (4) blanket
    contractual liability for all written and oral contracts; and (5)
    contractual liability covering the indemnities contained in Article 13
    hereof to the extent the same is available;

         (iii)   business income and rent loss insurance (A) with loss payable
    to Lender; (B) covering all risks required to be covered by the insurance
    provided for in Subsection 3.3(a)(i); (C) containing an extended period of
    indemnity endorsement which provides that after the physical loss to the
    Improvements and Personal Property has been repaired, the continued loss of
    income will be insured until such income either returns to the same level
    it was at prior to the loss, or the expiration of twelve (12) months from
    the date of the loss, whichever first occurs, and notwithstanding that the
    policy may expire prior to the end of such period; and (D) in an amount
    equal to 100% of the projected gross income from the Property for a period
    of twelve (12) months.  The amount of such business income insurance shall
    be determined prior to the date hereof and at least once each year
    thereafter based on the greatest of:  (x) Borrower's reasonable estimate of
    the gross income from the Property; (y) the estimate of gross income set
    forth in the annual operating budget delivered pursuant to Subsection
    3.11(a)(v); and (z) the highest gross income received during the term of
    the Note for any full calendar year prior to the date the amount of such
    insurance is being determined.  All insurance proceeds payable to Lender
    pursuant to this Subsection shall be held by Lender and shall be applied to
    the obligations secured hereunder from time to time due and payable
    hereunder and under the Note; provided, however, that nothing herein
    contained shall be deemed to relieve Borrower of its obligations to pay the
    obligations secured hereunder on the respective dates of payment provided
    for in the Note except to the extent such amounts are actually paid out of
    the proceeds of such business income insurance;


         (iv)    at all times during which structural construction, repairs or
    alterations are being made with respect to the Improvements (A) owner's
    contingent or protective liability insurance covering claims not covered by
    or under the terms or provisions of the above mentioned commercial general
    liability insurance policy; and (B) the insurance provided for in
    Subsection 3.3(a)(i) written in a so-called builder's risk completed value
    form (1) on a non-reporting basis, (2) against all risks insured against
    pursuant to Subsection 3.3(a)(i), (3) including permission to occupy the
    Property, and (4) with an agreed amount endorsement waiving co-insurance
    provisions;

         (v)     workers' compensation, subject to the statutory limits of the
    state in which the Property is located, and employer's liability insurance
    (A) with a limit per accident and per disease per employee, and (B) in an
    amount for disease aggregate in respect of any work or operations on or
    about the Property, or in connection with the Property or its operation (if
    applicable), in each case reasonably required by Lender;

         (vi)    comprehensive boiler and machinery insurance, if applicable,
    in amounts as shall be reasonably required by Lender on terms consistent
    with the 

                                        - 10 -


<PAGE>

    commercial general liability insurance policy required under Subsection
    3.3(a)(ii); and

         (vii)   umbrella liability insurance in an amount not less than
    $20,000,000 per occurrence on terms consistent with the commercial general
    liability insurance policy required under Subsection 3.3(a)(ii); 

         (viii)  motor vehicle liability coverage for all owned and non-owned
    vehicles, including rented and leased vehicles containing minimum limits
    per occurrence of $5,000,000; and

         (iv)    such other insurance and in such amounts as Lender from time
    to time may reasonably request against such other insurable hazards which
    at the time are commonly insured against for property similar to the
    Property located in or around the region in which the Property is located.

         (b)  All insurance provided for in Subsection 3.3(a) hereof shall be
obtained under valid and enforceable policies (the "Policies" or in the
singular, the "Policy"), and shall be subject to the approval of Lender as to
insurance companies, amounts, forms, deductibles, loss payees and insurers.  The
Policies shall be issued by financially sound and responsible insurance
companies authorized to do business in the state in which the Property is
located and approved by Lender.  Each insurance company must have a rating of
"A" or better for claims paying ability assigned by Standard & Poor's Rating
Group (the "Rating Agency") or, if the Rating Agency does not assign a rating
for such insurance company, such insurance company must have a general policy
rating of A or better and a financial class of VIII or better by A.M. Best
Company, Inc., and if there are any Securities (defined in Section 19.1 below)
issued which have been assigned a rating by a credit rating agency approved by
Lender (a "Rating Agency"), the insurance company shall have a claims paying
ability rating by such Rating Agency equal to or greater than the rating of the
highest class of the Securities (each such insurer shall be referred to below as
a "Qualified Insurer").  The Policies described in Subsections 3.3(a)(i), (iii),
(iv)(B) and (vi) shall designate Lender as loss payee.  Not less than thirty
(30) days prior to the expiration dates of the Policies theretofore furnished to
Lender pursuant to Subsection 3.3(a), certified copies of the Policies marked
"premium paid" or accompanied by evidence satisfactory to Lender of payment of
the premiums due thereunder (the "Insurance Premiums"), shall be delivered by
Borrower to Lender; provided, however, that in the case of renewal Policies,
Borrower may furnish Lender with binders therefor to be followed by the original
Policies when issued.

         (c)  Borrower shall not obtain (i) any umbrella or blanket liability
or casualty Policy unless, in each case, such Policy is approved in advance in
writing by Lender and Lender's interest is included therein as provided in this
Security Instrument and such Policy is issued by a Qualified Insurer, or (ii)
separate insurance concurrent in form or contributing in the event of loss with
that required in Subsection 3.3(a) to be furnished by, or which may be
reasonably required to be furnished by, Borrower.  In the event Borrower obtains
separate insurance or an umbrella or a blanket Policy, Borrower shall notify
Lender 

                                        - 11 -


<PAGE>

of the same and shall cause certified copies of each Policy to be delivered as
required in Subsection 3.3(a).  Any blanket insurance Policy shall (a)
specifically allocate to the Property the amount of coverage from time to time
required hereunder or (b) be written on an occurrence basis for the coverages
required hereunder with a limit per occurrence in an amount equal to the amount
of coverage required hereunder and shall otherwise provide the same protection
as would a separate Policy insuring only the Property in compliance with the
provisions of Subsection 3.3(a).

         (d)  All Policies of insurance provided for or contemplated by
Subsection 3.3(a), except for the Policy referenced in Subsection 3.3(a)(v),
shall name Lender and Borrower as the insured or additional insured, as their
respective interests may appear, and in the case of property damage, boiler and
machinery, flood and earthquake insurance, shall contain a so-called New York
standard non-contributing mortgagee clause in favor of Lender providing that the
loss thereunder shall be payable to Lender.

         (e)  All Policies of insurance provided for in Subsection 3.3(a) shall
contain clauses or endorsements to the effect that:

         (i)     no act or negligence of Borrower, or anyone acting for
    Borrower, or of any tenant under any Lease or other occupant, or failure to
    comply with the provisions of any Policy which might otherwise result in a
    forfeiture of the insurance or any part thereof, shall in any way affect
    the validity or enforceability of the insurance insofar as Lender is
    concerned;

         (ii)    the Policy shall not be materially changed (other than to
    increase the coverage provided thereby) or cancelled without at least 30
    days' written notice to Lender and any other party named therein as an
    insured; and

         (iii)   each Policy shall provide that the issuers thereof shall give
    written notice to Lender if the Policy has not been renewed thirty (30)
    days prior to its expiration; and

         (iv)    Lender shall not be liable for any Insurance Premiums thereon
    or subject to any assessments thereunder.

         (f)  Borrower shall furnish to Lender, on or before thirty (30) days
after the close of each of Borrower's fiscal years, a statement certified by
Borrower or a duly authorized officer of Borrower of the amounts of insurance
maintained in compliance herewith, of the risks covered by such insurance and of
the insurance company or companies which carry such insurance and, if requested
by Lender, verification of the adequacy of such insurance by an independent
insurance broker or appraiser acceptable to Lender.

         (g)  If at any time Lender is not in receipt of written evidence that
all insurance required hereunder is in full force and effect, Lender shall have
the right, without 

                                        - 12 -


<PAGE>

notice to Borrower to take such action as Lender deems necessary to protect its
interest in the Property, including, without limitation, the obtaining of such
insurance coverage as Lender in its sole discretion deems appropriate, and all
expenses incurred by Lender in connection with such action or in obtaining such
insurance and keeping it in effect shall be paid by Borrower to Lender upon
demand and until paid shall be secured by this Security Instrument and shall
bear interest in accordance with Section 10.3 hereof.

         (h)  If the Property shall be damaged or destroyed, in whole or in
part, by fire or other casualty, Borrower shall give prompt notice of such
damage to Lender and shall promptly commence and diligently prosecute the
completion of the repair and restoration of the Property as nearly as possible
to the condition the Property was in immediately prior to such fire or other
casualty, with such alterations as may be approved by Lender (the "Restoration")
and otherwise in accordance with Section 4.4 of this Security Instrument. 
Borrower shall pay all costs of such Restoration whether or not such costs are
covered by insurance.  Lender may, but shall not be obligated to make proof of
loss if not made promptly by Borrower;

         (i)  In the event of foreclosure of this Security Instrument, or other
transfer of title to the Property in extinguishment in whole or in part of the
Debt all right, title and interest of Borrower in and to such policies then in
force concerning the Property and all proceeds payable thereunder shall
thereupon be assigned to and shall vest in the purchaser at such foreclosure or
Lender or other transferee in the event of such other transfer of title.

         Section 3.4    PAYMENT OF TAXES, ETC.  (a)  Borrower shall promptly
pay all taxes, assessments, water rates, sewer rents, governmental impositions,
and other charges, including without limitation vault charges and license fees
for the use of vaults, chutes and similar areas adjoining the Land,  now or
hereafter levied or assessed or imposed against the Property or any part thereof
(the "Taxes"), all ground rents, maintenance charges and similar charges, now or
hereafter levied or assessed or imposed against the Property or any part thereof
(the "Other Charges"), and all charges for utility services provided to the
Property as same become due and payable.  Borrower will deliver to Lender,
promptly upon Lender's request, evidence satisfactory to Lender that the Taxes,
Other Charges and utility service charges have been so paid or are not then
delinquent.  Borrower shall not suffer and shall promptly cause to be paid and
discharged any lien or charge whatsoever which may be or become a lien or charge
against the Property.  Except to the extent sums sufficient to pay all Taxes and
Other Charges have been deposited with Lender in accordance with the terms of
this Security Instrument, Borrower shall furnish to Lender paid receipts for the
payment of the Taxes and Other Charges prior to the date the same shall become
delinquent.

         (b)  After prior written notice to Lender, Borrower, at its own
expense, may contest by appropriate legal proceeding, promptly initiated and
conducted in good faith and with due diligence, the amount or validity or
application in whole or in part of any of the Taxes, provided that (i) no event,
act or condition which, with the giving of notice or lapse of time, or both,
would constitute an Event of Default (a"Default") or Event of Default 


                                        - 13 -


<PAGE>

has occurred and is continuing under the Loan Agreement, the Note, this Security
Instrument or any of the Other Security Documents, (ii) Borrower is permitted to
do so under the provisions of any other mortgage, deed of trust or deed to
secure debt affecting the Property, (iii) such proceeding shall suspend the
collection of the Taxes from Borrower and from the Property or Borrower shall
have paid all of the Taxes under protest, (iv) such proceeding shall be
permitted under and be conducted in accordance with the provisions of any other
instrument to which Borrower is subject and shall not constitute a default
thereunder, (v) neither the Property nor any part thereof or interest therein
will be in danger of being sold, forfeited, terminated, cancelled or lost, (vi)
Borrower shall have deposited with Lender adequate reserves for the payment of
the Taxes, together with all interest and penalties thereon, unless Borrower has
paid all of the Taxes under protest, and (vii) Borrower shall have furnished the
security as may be required in the proceeding, or as may be requested by Lender
to insure the payment of any contested Taxes, together with all interest and
penalties thereon.

         Section 3.5    ESCROW FUND.  In addition to the initial deposits with
respect to Taxes and Insurance Premiums made by Borrower to Lender on the date
hereof to be held by Lender in escrow, Borrower shall pay to Lender on the first
day of each calendar month (a) one-twelfth of an amount which would be
sufficient to pay the Taxes payable, or estimated by Lender to be payable,
during the next ensuing twelve (12) months and (b) one-twelfth of an amount
which would be sufficient to pay the Insurance Premiums due for the renewal of
the coverage afforded by the Policies upon the expiration thereof (the amounts
in (a) and (b) above shall be called the "Escrow Fund").  Borrower agrees to
notify Lender immediately of any changes to the amounts, schedules and
instructions for payment of any Taxes and Insurance Premiums of which it has
obtained knowledge and authorizes Lender or its agent to obtain the bills for
Taxes and Other Charges directly from the appropriate taxing authority.  The
Escrow Fund and the payments of interest or principal or both, payable pursuant
to the Note shall be added together and shall be paid as an aggregate sum by
Borrower to Lender.  Lender will apply the Escrow Fund to payments of Taxes and
Insurance Premiums required to be made by Borrower pursuant to Sections 3.3 and
3.4 hereof.  If the amount of the Escrow Fund shall exceed the amounts due for
Taxes and Insurance Premiums pursuant to Sections 3.3 and 3.4 hereof, Lender
shall, in its discretion, return any excess to Borrower or credit such excess
against future payments to be made to the Escrow Fund.  In allocating such
excess, Lender may deal with the person shown on the records of Lender to be the
owner of the Property.  If the Escrow Fund is not sufficient to pay the items
set forth in (a) and (b) above, Borrower shall promptly pay to Lender, upon
demand, an amount which Lender shall estimate as sufficient to make up the
deficiency.  The Escrow Fund shall be held in a non-interest bearing account and
shall not constitute a trust fund and may be commingled with other monies held
by Lender.  No earnings or interest on the Escrow Fund shall be payable to
Borrower.

         Section 3.6    CONDEMNATION.  Borrower shall promptly give Lender
notice of the actual or threatened commencement of any condemnation or eminent
domain proceeding and shall deliver to Lender copies of any and all papers
served in connection with 

                                        - 14 -


<PAGE>

such proceedings.  Lender may participate in any such proceedings, and Borrower
shall from time to time deliver to Lender all instruments requested by it to
permit such participation.  Borrower shall, at its expense, diligently prosecute
any such proceedings, and shall consult with Lender, its attorneys and experts,
and cooperate with them in the carrying on or defense of any such proceedings.
Notwithstanding any taking by any public or quasi-public authority through
eminent domain or otherwise (including but not limited to any transfer made in
lieu of or in anticipation of the exercise of such taking), Borrower shall
continue to pay the Debt at the time and in the manner provided for its payment
in the Note and in this Security Instrument and the Debt shall not be reduced
until any award or payment therefor shall have been actually received and
applied by Lender, after the deduction of expenses of collection, to the
reduction or discharge of the Debt.  Lender shall not be limited to the interest
paid on the award by the condemning authority but shall be entitled to receive
out of the award interest at the rate or rates provided herein or in the Note. 
If the Property or any portion thereof is taken by a condemning authority,
Borrower shall promptly commence and diligently prosecute the Restoration of the
Property and otherwise comply with the provisions of Section 4.4 of this
Security Instrument.  In the event Lender is not required to disburse Net
Proceeds (as defined herein) to Borrower in accordance with Section 4.4 of this
Security Instrument, Lender may apply any award or payment to the reduction or
discharge of the Debt whether or not then due and payable.  The amount of any
award or payment so applied in excess of the Debt shall be returned to Borrower.
If the Property is sold, through foreclosure or otherwise, prior to the receipt
by Lender of the award or payment, Lender shall have the right, whether or not a
deficiency judgment on the Note shall have been sought, recovered or denied, to
receive the award or payment, or a portion thereof sufficient to pay the Debt.

         Section 3.7    LEASES AND RENTS.  (a)  Except as otherwise consented
to by Lender, all Leases shall be written on the standard form of lease which
shall have been approved by Lender.  Upon request, Borrower shall furnish Lender
with executed copies of all Leases.  No material changes may be made to the
Lender-approved standard lease without the prior written consent of Lender.  In
addition, all renewals of Leases and all proposed leases shall provide for
rental rates and terms comparable to existing local market rates and terms and
shall be arms-length transactions with bona fide, independent third party
tenants.  All proposed Leases and renewals of existing Leases shall be subject
to the prior approval of Lender and its counsel, at Borrower's expense.  All
Leases shall provide that they are subordinate to this Security Instrument and
that the lessee agrees to attorn to Lender.  Borrower (i) shall observe and
perform all the obligations imposed upon the lessor under the Leases and shall
not do or permit to be done anything to impair the value of the Leases as
security for the Debt; (ii) shall promptly send copies to Lender of all notices
of default which Borrower shall send or receive thereunder; (iii) shall enforce
all of the terms, covenants and conditions contained in the Leases upon the part
of the lessee thereunder to be observed or performed, short of termination
thereof; (iv) shall not collect any of the Rents more than one (1) month in
advance; (v) shall not execute any other assignment of the lessor's interest in
the Leases or the Rents; (vi) shall not alter, modify or change the terms of the
Leases without the prior written consent of Lender, or cancel or terminate the
Leases or accept a 

                                        - 15 -

surrender thereof or convey or transfer or suffer or permit a conveyance or
transfer of the Land or of any interest therein so as to effect a merger of the
estates and rights of, or a termination or diminution of the obligations of,
lessees thereunder; (vii) shall not alter, modify or change the terms of any
guaranty, letter of credit or other credit support with respect to the Leases
(the "Lease Guaranty") or cancel or terminate such Lease Guaranty without the
prior written consent of Lender; and (viii) shall not consent to any assignment
of or subletting under the Leases not in accordance with their terms, without
the prior written consent of Lender.  Borrower agrees that it will give prompt
notice to Lender at any time that (A) Leases comprising more than five percent
(5%) of the leasable space in the Property, whether individually or in the
aggregate, are terminated or have expired and have not been renewed by the
related tenant thereunder or (B) tenants under Leases comprising more than five
percent (5%) of the leasable space in the Property, whether individually or in
the aggregate, have vacated their leased space, ceased operating their business
in such space, have subleased such space, commenced any action or proceeding
relating to bankruptcy, made an assignment for the benefit of creditors or
availed themselves or have been subjected to any similar action or proceeding.

         (b)  COMMERCIAL PROPERTY.  Notwithstanding the provisions of
Subsection 3.7(a) above, renewals of existing commercial Leases and proposed
Leases for commercial space shall not be subject to the prior approval of Lender
provided all of the following conditions are satisfied: (i) the rental income
pursuant to the renewal or proposed Lease is not more than ten percent (10%) of
the total rental income for the Property, (ii) the renewal or proposed Lease
covers less than ten percent (10%) of the Property, in the aggregate, ((i) and
(ii), "Minor Leases"), (iii) the renewal or proposed Lease shall provide for
rental rates and terms comparable to existing local market rates and terms, (iv)
the renewal or proposed Lease shall be an arms-length transaction with a bona
fide, independent third party tenant and (vi) the renewal or proposed Lease
shall satisfy other criteria as shall be required by Lender in its sole
discretion and of which Borrower has been notified by Lender.  Borrower shall
deliver to Lender copies of all Leases which are entered into pursuant to the
preceding sentence together with Borrower's certification that it has satisfied
all of the conditions of the preceding sentence within thirty (30) days after
the execution of the Lease.

         (c)  To the extent permitted by law, Borrower shall promptly deposit
with Lender any and all monies representing security deposits under the Leases,
whether or not Borrower actually received such monies (the "Security Deposits").
Lender shall hold the Security Deposits in accordance with the terms of the
respective Lease, and shall only release the Security Deposits in order to
return a tenant's Security Deposit to such tenant if such tenant is entitled to
the return of the Security Deposit under the terms of the Lease and is not
otherwise in default under the Lease.  To the extent required by Applicable Laws
(defined below), Lender shall hold the Security Deposits in an interest bearing
account selected by Lender in its sole discretion.  The provisions of this
Section 3.7(c) shall be applicable only upon notification by Lender, which
notification may take place at any time a Default or Event of Default has
occurred and is continuing.  If such Security Deposits are held by Borrower,
Borrower shall deposit the Security Deposits into a segregated account with a

         Section 3.8    MAINTENANCE OF PROPERTY.  Borrower shall cause the
Property to be maintained in a good and safe condition and repair.  The
Improvements and the Personal Property shall not be removed, demolished or
materially altered (except for normal replacement of the Personal Property)
without the consent of Lender.  Borrower shall promptly repair, replace or
rebuild any part of the Property which may be destroyed by any casualty, or
become damaged, worn or dilapidated or which may be affected by any proceeding
of the character referred to in Section 3.6 hereof and shall complete and pay
for any structure at any time in the process of construction or repair on the
Land.  Borrower shall not initiate, join in, acquiesce in, or consent to any
change in any private restrictive covenant, zoning law or other public or
private restriction, limiting or defining the uses which may be made of the
Property or any part thereof.  If under applicable zoning provisions the use of
all or any portion of the Property is or shall become a nonconforming use,
Borrower will not cause or permit the nonconforming use to be discontinued or
abandoned without the express written consent of Lender.

         Section 3.9    WASTE.  Borrower shall not commit or suffer any waste
of the Property or make any change in the use of the Property which will in any
way materially increase the risk of fire or other hazard arising out of the
operation of the Property, or take any action that might invalidate or give
cause for cancellation of any Policy, or do or permit to be done thereon
anything that may in any way impair the value of the Property or the security of
this Security Instrument.  Borrower will not, without the prior written consent
of Lender, permit any drilling or exploration for or extraction, removal, or
production of any minerals from the surface or the subsurface of the Land,
regardless of the depth thereof or the method of mining or extraction thereof.

         Section 3.10   COMPLIANCE WITH LAWS.  (a)  Borrower shall promptly
comply with all existing and future federal, state and local laws, orders,
ordinances, governmental rules and regulations or court orders affecting or
which may be interpreted to affect the Property, or the use thereof including,
but not limited to, the Americans with Disabilities Act ("ADA") (collectively,
the "Applicable Laws").

         (b) Borrower shall from time to time, upon Lender's request, provide
Lender with evidence satisfactory to Lender that the Property complies with all
Applicable Laws or is exempt from compliance with Applicable Laws.

         (c) Notwithstanding any provisions set forth herein or in any document
regarding Lender's approval of alterations of the Property, Borrower shall not
alter the Property in any manner which would increase Borrower's
responsibilities for compliance with Applicable Laws without the prior written
approval of Lender.  Lender's approval of the plans, specifications, or working
drawings for alterations of the Property shall create no responsibility or
liability on behalf of Lender for their completeness, design, sufficiency or
their compliance with Applicable Laws.  The foregoing shall apply to tenant
improvements

Borrower of any notice related to a violation of any Applicable Laws and of the

         Section 3.12   PAYMENT FOR LABOR AND MATERIALS.  Borrower will
promptly pay when due all bills and costs for labor, materials, and specifically
fabricated materials incurred in connection with the Property and never permit
to exist beyond the due date thereof in respect of the Property or any part
thereof any lien or security interest, even though inferior to the liens and the
security interests hereof, and in any event never permit to be created or exist
in respect of the Property or any part thereof any other or additional lien or
security interest other than the liens or security interests hereof, except for
the Permitted Exceptions (defined below).

         Section 3.13   MANAGEMENT AGREEMENTS.  (a) If the Improvements are
operated under the terms and conditions of that certain management agreement
dated ________ between Borrower and ________ (the "Manager"), (hereinafter,
together with any renewals or replacements thereof, being referred to as the
"Management Agreement"), which Management Agreement has been approved by Lender.
Borrower shall (i) diligently perform and observe all of the terms, covenants
and conditions of the Management Agreement on the part of Borrower to be
performed and observed to the end that all things shall be done which are
necessary to keep unimpaired the rights of Borrower under the Management
Agreement and (ii) promptly notify Lender of the giving of any notice to
Borrower of any default by Borrower in the performance or observance of any of
the terms, covenants or conditions of the Management Agreement on the part of
Borrower to be performed and observed and deliver to Lender a true copy of each
such notice.  Borrower shall not surrender the Management Agreement, consent to
the assignment by the Manager of its interest under the Management Agreement, or
terminate or cancel the Management Agreement or modify, change, supplement,
alter or amend the Management Agreement, in any respect, either orally or in
writing, and Borrower hereby assigns to Lender as further security for the
payment of the Debt and for the performance and observance of the terms,
covenants and conditions of this Security Instrument, all the rights, privileges
and prerogatives of Borrower to surrender the Management Agreement or to
terminate, cancel, modify, change, supplement, alter or amend the Management
Agreement in any respect, and any such surrender of the Management Agreement or
termination, cancellation, modification, change, supplement, alteration or
amendment of the Management Agreement without the prior consent of Lender shall
be void and of no force and effect.  If Borrower shall default in the
performance or observance of any material term, covenant or condition of the
Management Agreement on the part of Borrower to be performed or observed, then,
without limiting the generality of the other provisions of this Security
Instrument, and without waiving or releasing Borrower from any of its
obligations hereunder, Lender shall have the right, but shall be under no
obligation, to pay any sums and to perform any act or take any action as may be
appropriate to cause all the terms, covenants and conditions of the Management
Agreement on the part of Borrower to be performed or observed to be promptly
performed or observed on behalf of Borrower, to the end that the rights of
Borrower in, to and under the Management Agreement shall be kept unimpaired and
free from default.  Lender and any person designated by Lender shall have, and
are hereby granted, the right to enter upon the Property at any time and from
time to time for the purpose of taking any such action.  If the Manager under
the Management Agreement shall deliver to Lender a copy of any notice sent to 

                                        - 20 -

Borrower of default under the Management Agreement, such notice shall constitute
full protection to Lender for any action taken or omitted to be taken by Lender
in good faith, in reliance thereon.  Borrower shall notify Lender if the Manager
sub-contracts to a third party or an Affiliate (hereinafter defined) any or all
of its management responsibilities under the Management Agreement.  Borrower
shall, from time to time, use its best efforts to obtain from the Manager under
the Management Agreement such certificates of estoppel with respect to
compliance by Borrower with the terms of the Management Agreement as may be
requested by Lender.  Borrower shall exercise each individual option, if any, to
extend or renew the term of the Management Agreement upon demand by Lender made
at any time within one (1) year of the last day upon which any such option may
be exercised, and Borrower hereby expressly authorizes and appoints Lender its
attorney-in-fact to exercise any such option in the name of and upon behalf of
Borrower, which power of attorney shall be irrevocable and shall be deemed to be
coupled with an interest.  Any sums expended by Lender pursuant to this
paragraph shall bear interest at the Default Rate (hereinafter defined) from the
date such cost is incurred to the date of payment to Lender, shall be deemed to
constitute a portion of the Debt, shall be secured by the lien of this Security
Instrument and the other Loan Documents and shall be immediately due and payable
upon demand by Lender therefor.

         (b)     Without limitation of the foregoing, if (i) the Manager shall
become insolvent, or (ii) a Default or Event of Default shall occur and be
continuing, then Lender, at its option, may require Borrower to engage a
bona-fide, independent third party management agent approved by Lender in its
sole discretion (the "New Manager") to manage the Property.  The New Manager
shall be engaged by Borrower pursuant to a written management agreement that
complies with the terms hereof and is otherwise satisfactory to Lender in all
respects.

         Section 3.14   PERFORMANCE OF OTHER AGREEMENTS.  Borrower shall
observe and perform each and every term to be observed or performed by Borrower
pursuant to the terms of any agreement or recorded instrument affecting or
pertaining to the Property, or given by Borrower to Lender for the purpose of
further securing an obligation secured hereby and any amendments, modifications
or changes thereto.

business transactions with any Affiliate of Borrower or of any general partner
or Borrower unless the terms and conditions thereof will be intrinsically fair,
at not more than market rates and substantially similar or more favorable to
those that would be available on an arms-length basis with persons or entities
that are not affiliated with each other.  The term "Affiliate" shall mean with
reference to a specified person that directly or indirectly through one or more
intermediaries Controls (hereinafter defined) or is controlled by or is under
common Control with the specified person.  The term "Control" shall mean in all
cases, the power directly or indirectly, to direct or control, or cause the
direction of, the management policies of another person, whether through the
ownership of voting securities, general partnership interests, common directors,
trustees, officers by contract or otherwise.  The

not change Borrower's name, identity (including its trade name or names), chief
executive office, principal place of business or, if not an individual,
Borrower's corporate, partnership or other structure without notifying the
Lender of such change in writing at least thirty (30) days prior to the
effective date of such change and, in the case of a change in Borrower's
structure, without first obtaining the prior written consent of the Lender.
Borrower will execute and deliver to the Lender, prior to or contemporaneously
with the effective date of any such change, any financing statement or financing
statement change required by the Lender to establish or maintain the validity,
perfection and priority of the security interest granted herein. At the request
of the Lender, Borrower shall execute a certificate in form satisfactory to the
Lender listing the trade names under which Borrower intends to operate the
Property, and representing and warranting that Borrower does business under no
other trade name with respect to the Property.

    (iii)     All plans and specifications required in connection with the
    Restoration shall be subject to prior review and acceptance in all respects
    by Lender and by an independent consulting engineer selected by Lender (the
    "Restoration Consultant"). Lender shall have the use of the plans and
    specifications and all permits, licenses and approvals required or obtained
    in connection with the Restoration.  The identity of the contractors,
    subcontractors and materialmen engaged in the Restoration, as well as the
    contracts under which they have been engaged, shall be subject to prior
    review and acceptance by Lender and the Restoration Consultant.  All costs
    and expenses incurred by Lender in connection with making the Net Proceeds
    available for the Restoration including, without limitation, reasonable
    counsel fees and disbursements and the Restoration Consultant's fees, shall
    be paid by Borrower.

     (iv)     In no event shall Lender be obligated to make disbursements of
    the Net Proceeds in excess of an amount equal to the costs actually
    incurred from time to time for work in place as part of the Restoration, as
    certified by the Restoration Consultant, MINUS the Casualty Retainage.  The
    term "Casualty Retainage" as used in this Subsection 4.4(b) shall mean an
    amount equal to 10% of the costs actually incurred for work in place as
    part of the Restoration, as certified by the Restoration Consultant, until
    the Restoration has been completed.  The Casualty Retainage shall in no
    event, and notwithstanding anything to the contrary set forth above in this
    Subsection 4.4(b), be less than the amount actually held back by Borrower
    from contractors, subcontractors and materialmen engaged in the
    Restoration.  The Casualty Retainage shall not be released until the
    Restoration Consultant certifies to Lender that the Restoration has been
    completed in accordance with the provisions of this Subsection 4.4(b) and
    that all approvals necessary for the re-occupancy and use of the Property
    have been obtained from all appropriate governmental and quasi-governmental
    authorities, and Lender receives evidence satisfactory to Lender that the
    costs of the Restoration have been paid in full or will be paid in full out
    of the Casualty Retainage, provided, however, that Lender will release the
    portion of the Casualty Retainage being held with respect to any
    contractor, subcontractor or materialman engaged in the Restoration as of
    the date upon which the Restoration Consultant certifies to Lender that the
    contractor, subcontractor or materialman has satisfactorily completed all
    work and has supplied all materials in accordance with the provisions of
    the contractor's, subcontractor's or materialman's contract, and the
    contractor, subcontractor or materialman delivers the lien waivers and
    evidence of payment in full of all sums due to the contractor,
    subcontractor or materialman as may be reasonably requested by Lender or by
    the title company insuring the lien of this Security Instrument.  If
    required by Lender, the release of any such portion of the Casualty
    Retainage shall be approved by the surety company, if any, which has issued
    a payment or performance bond with respect to the contractor, subcontractor
    or materialman.

      (v)     Lender shall not be obligated to make disbursements of the Net
    Proceeds more frequently than once every calendar month.

<PAGE>

     (vi)     If at any time the Net Proceeds or the undisbursed balance
    thereof shall not, in the opinion of Lender, be sufficient to pay in full
    the balance of the costs which are estimated by the Restoration Consultant
    to be incurred in connection with the completion of the Restoration,
    Borrower shall deposit the deficiency (the "Net Proceeds Deficiency") with
    Lender before any further disbursement of the Net Proceeds shall be made. 
    The Net Proceeds Deficiency deposited with Lender shall be held by Lender
    and shall be disbursed for costs actually incurred in connection with the
    Restoration on the same conditions applicable to the disbursement of the
    Net Proceeds, and until so disbursed pursuant to this Subsection 4.4(b)
    shall constitute additional security for the Obligations.

    (vii)     The excess, if any, of the Net Proceeds and the remaining
    balance, if any, of the Net Proceeds Deficiency deposited with Lender after
    the Restoration Consultant certifies to Lender that the Restoration has
    been completed in accordance with the provisions of this Subsection 4.4(b),
    and the receipt by Lender of evidence satisfactory to Lender that all costs
    incurred in connection with the Restoration have been paid in full, shall
    be remitted by Lender to Borrower, provided no Default or Event of Default
    shall have occurred and shall be continuing under the Loan Agreement, the
    Note, this Security Instrument or any of the Other Security Documents.

         (c)  All Net Proceeds not required (i) to be made available for the
Restoration or (ii) to be returned to Borrower as excess Net Proceeds pursuant
to Subsection 4.4(b)(vii) may be retained and applied by Lender toward the
payment of the Debt whether or not then due and payable in such order, priority
and proportions as Lender in its discretion shall deem proper or, at the
discretion of Lender, the same may be paid, either in whole or in part, to
Borrower for such purposes as Lender shall designate, in its discretion. If
Lender shall receive and retain Net Proceeds, the lien of this Security
Instrument shall be reduced only by the amount thereof received and retained by
Lender and actually applied by Lender in reduction of the Debt.

                        ARTICLE 6 - OBLIGATIONS AND RELIANCES

         Section 6.1    RELATIONSHIP OF BORROWER AND LENDER.  The relationship
between Borrower and Lender is solely that of debtor and creditor, and Lender
has no fiduciary or other special relationship with Borrower, and no term or
condition of any of the Note, this Security Instrument and the Other Security
Documents shall be construed so as to deem the relationship between Borrower and
Lender to be other than that of debtor and creditor.

         Section 6.2    NO RELIANCE ON LENDER.  The general partners, officers,
principals and (if Borrower is a trust) beneficial owners of Borrower are
experienced in the ownership and operation of properties similar to the
Property, and Borrower and Lender are relying solely upon such expertise and
business plan in connection with the ownership and operation of the Property. 
Borrower is not relying on Lender's expertise, business acumen or advice in
connection with the Property.

         Section 6.3    NO LENDER OBLIGATIONS.  (a)  Notwithstanding the
provisions of Subsections 1.1(f) and (l) or Section 1.2, Lender is not
undertaking the performance of (i) any obligations under the Leases; or (ii) any
obligations with respect to such agreements, contracts, certificates,
instruments, franchises, permits, trademarks, licenses and other documents.

         (b)  By accepting or approving anything required to be observed,
performed or fulfilled or to be given to Lender pursuant to this Security
Instrument, the Note or the Other Security Documents, including without
limitation, any officer's certificate, balance sheet, statement of profit and
loss or other financial statement, survey, appraisal, or insurance policy,
Lender shall not be deemed to have warranted, consented to, or affirmed the
sufficiency, the legality or effectiveness of same, and such acceptance or
approval thereof shall not constitute any warranty or affirmation with respect
thereto by Lender.

         Section 6.4    RELIANCE. Borrower recognizes and acknowledges that in
accepting the Loan Agreement, the Note, this Security Instrument and the Other
Security Documents, Lender is expressly and primarily relying on the truth and
accuracy of the warranties and representations set forth in Article 5 without
any obligation to investigate the Property and notwithstanding any investigation
of the Property by Lender; that such reliance existed on the part of Lender
prior to the date hereof; that the warranties and representations are a material
inducement to Lender in accepting the Loan Agreement, the Note, this Security
Instrument and the Other Security Documents; and that Lender would not be
willing to make the loan evidenced by the Loan Agreement, the Note, this
Security Instrument and the Other Security Documents and accept this Security
Instrument in the absence of the warranties and representations as set forth in
Article 5.

         Section 7.1    RECORDING OF SECURITY INSTRUMENT, ETC.  Borrower
forthwith upon the execution and delivery of this Security Instrument and
thereafter, from time to time, will cause this Security Instrument and any of
the Other Security Documents creating a lien or security interest or evidencing
the lien hereof upon the Property and each instrument of further assurance to be
filed, registered or recorded in such manner and in such places as may be
required by any present or future law in order to publish notice of and fully to
protect and perfect the lien or security interest hereof upon, and the interest
of Lender in, the Property.  Borrower will pay all taxes, filing, registration
or recording fees, and all expenses incident to the preparation, execution,
acknowledgment and/or recording of the Note, this Security Instrument, the Other
Security Documents, any note or mortgage supplemental hereto, any security
instrument with respect to the Property and any instrument of further assurance,
and any modification or amendment of the foregoing documents, and all federal,
state, county and municipal taxes, duties, imposts, assessments and charges
arising out of or in connection with the execution and delivery of this Security
Instrument, any mortgage supplemental hereto, any security instrument with
respect to the Property or any instrument of further assurance, and any
modification or amendment of the foregoing documents, except where prohibited by
law so to do.

         Section 7.2    FURTHER ACTS, ETC.  Borrower will, at the cost of
Borrower, and without expense to Lender, do, execute, acknowledge and deliver
all and every such further acts, deeds, conveyances, mortgages, assignments,
notices of assignments, transfers and assurances as Lender shall, from time to
time, require, for the better assuring, conveying, assigning, transferring, and
confirming unto Lender the property and rights hereby mortgaged, granted,
bargained, sold, conveyed, confirmed, pledged, assigned, warranted and
transferred or intended now or hereafter so to be, or which Borrower may be or
may hereafter become bound to convey or assign to Lender, or for carrying out
the intention or facilitating the performance of the terms of this Security
Instrument or for filing, registering or recording this Security Instrument, or
for complying with all Applicable Laws.  Borrower, on demand, will execute and
deliver and hereby authorizes Lender to execute in the name of Borrower or
without the signature of Borrower to the extent Lender may lawfully do so, one
or more financing statements, chattel mortgages or other instruments, to
evidence more effectively the security interest of Lender in the Property. 
Borrower grants to Lender an irrevocable power of attorney coupled with an
interest for the purpose of exercising and perfecting any and all rights and
remedies available to Lender at law and in equity, including without limitation
such rights and remedies available to Lender pursuant to this Section 7.2.


         Section 7.3    CHANGES IN TAX, DEBT, CREDIT AND DOCUMENTARY STAMP
LAWS.  (a) If any law is enacted or adopted or amended after the date of this

                                        - 34 -


<PAGE>

Property, Borrower will pay the tax, with interest and penalties thereon, if
any.  If Lender is advised by counsel chosen by it that the payment of tax by
Borrower would be unlawful or taxable to Lender or unenforceable or provide the
basis for a defense of usury, then Lender shall have the option by written
notice of not less than ninety (90) days to declare the Debt immediately due and
payable.

         (b)  Borrower will not claim or demand or be entitled to any credit or
credits on account of the Debt for any part of the Taxes or Other Charges
assessed against the Property, or any part thereof, and no deduction shall
otherwise be made or claimed from the assessed value of the Property, or any
part thereof, for real estate tax purposes by reason of this Security Instrument
or the Debt.  If such claim, credit or deduction shall be required by law,
Lender shall have the option, by written notice of not less than ninety (90)
days, to declare the Debt immediately due and payable.

         (c)  If at any time the United States of America, any State thereof or
any subdivision of any such State shall require revenue or other stamps to be
affixed to the Note, this Security Instrument, or any of the Other Security
Documents or impose any other tax or charge on the same, Borrower will pay for
the same, with interest and penalties thereon, if any.

         Section 7.4    ESTOPPEL CERTIFICATES.  (a) After request by Lender,
Borrower, within ten (10) days, shall furnish Lender or any proposed assignee
with a statement, duly acknowledged and certified, setting forth (i) the amount

full force and effect and (provided the Property is not a residential
multifamily property) have not been modified (or if modified, setting forth all
modifications), (x) the date to which the Rents thereunder have been paid
pursuant to the Leases, (xi) whether or not, to the best knowledge of Borrower,
any of the lessees under the Leases are in default under the Leases, and, if any
of the lessees are in default, setting forth the specific nature of all such
defaults, (xii) the amount of security deposits held by Borrower under each
Lease and that such amounts are consistent with the amounts required under each
Lease, and (xiii) as to any other matters reasonably requested by Lender and
reasonably related to the Leases, the obligations secured hereby, the Property
or this Security Instrument.

         (b)  Borrower shall deliver to Lender, promptly upon request, duly
executed estoppel certificates from any one or more lessees as required by
Lender attesting to such facts regarding the Leases as Lender may require,
including but not limited to attestations 

                                        - 35 -


<PAGE>


that each Lease covered thereby is in full force and effect with no defaults
thereunder on the part of any party, that none of the Rents have been paid more
than one month in advance, and that the lessee claims no defense or offset
against the full and timely performance of its obligations under the Lease.

         (c)  Upon any transfer or proposed transfer contemplated by Section
19.1 hereof, at Lender's request, Borrower shall provide an estoppel certificate

require.

         (d)  The delivery by Borrower and Lender of estoppel certificates and
similar statements shall otherwise be governed by the Loan Agreement.

         Section 7.5    FLOOD INSURANCE.  After Lender's request, Borrower
shall deliver evidence satisfactory to Lender that no portion of the
Improvements is situated in a federally designated "special flood hazard area"
or, if located with such area, Borrower shall maintain the insurance prescribed

and satisfied, at the sole election of Lender, be split or divided into two or
more notes and two or more security instruments, each of which shall cover all
or a portion of the Property to be more particularly described therein.  To that
end, Borrower, upon written request of Lender, shall execute, acknowledge and
deliver, or cause to be executed, acknowledged and delivered by the then owner
of the Property, to Lender and/or its designee or designees substitute notes and
security instruments in such principal amounts, aggregating not more than the
then unpaid principal amount of this Security Instrument, and containing terms,
provisions and clauses similar to those contained herein and in the Note, and
such other documents and instruments as may be required by Lender.

an officer of Lender as to the loss, theft, destruction or mutilation of the
Note or any Other Security Document which is not of public record, and, in the
case of any such mutilation, upon surrender and cancellation of such Note or
Other Security Document, Borrower will issue, in lieu thereof, a replacement
Note or Other Security Document, dated the date of such lost, stolen, destroyed

                         ARTICLE 8 - DUE ON SALE/ENCUMBRANCE

         Section 8.1    LENDER RELIANCE.  Borrower acknowledges that Lender has
examined and relied on the experience of Borrower and its general partner in
owning and operating properties such as the Property in agreeing to make the
loan secured hereby, and will continue to rely on Borrower's ownership of the
Property as a means of maintaining the value of the Property as security for
repayment of the Debt and the performance of the Other Obligations.  Borrower
acknowledges that Lender has a valid interest in maintaining the value of the
Property so as to ensure that, should Borrower default in the repayment of the
Debt or the performance of the Other Obligations, Lender can recover the Debt by
a sale of the Property.  

         Section 8.2    NO SALE/ENCUMBRANCE.  Borrower agrees that Borrower
shall not, without the prior written consent of Lender, sell, convey, mortgage,
grant, bargain, encumber, pledge, assign, or otherwise transfer the Property or
any part thereof or permit the Property or any part thereof to be sold,
conveyed, mortgaged, granted, bargained, encumbered, pledged, assigned, or
otherwise transferred.

         Section 8.3    SALE/ENCUMBRANCE DEFINED.  A sale, conveyance,
mortgage, grant, bargain, encumbrance, pledge, assignment, or transfer within
the meaning of this Article 8 shall be deemed to include, but not limited to,
(a) an installment sales agreement wherein Borrower agrees to sell the Property
or any part thereof for a price to be paid in installments; (b) an agreement by
Borrower leasing all or a substantial part of the Property for other than actual
occupancy by a space tenant thereunder or a sale, assignment or other transfer
of, or the grant of a security interest in, Borrower's right, title and interest
in and to any Leases or any Rents; (c) if Borrower or any general partner or
limited partner of Borrower is a corporation, the voluntary or involuntary sale,
conveyance, transfer or pledge of such corporation's stock or the stock of any
corporation directly or indirectly controlling such corporation by operation of
law or otherwise (other than transfers of shares in the REIT, or the creation or
issuance of new stock by which an aggregate of more than 20% of such
corporation's stock shall be vested in a party or parties who are not now
stockholders; and (d) if Borrower or any general partner or limited partner of
Borrower is a limited or general partnership or joint venture, the change,
removal or resignation of a general partner, managing partner or limited
partner, or the transfer or pledge of the partnership interest of any general
partner, managing partner or limited partner or any profits or proceeds relating
to such partnership interest whether in one transfer or a series of transfers. 
Notwithstanding the foregoing, transfer by devise or descent or by operation of
law upon the death of a partner or stockholder of Borrower or any general
partner thereof shall not be deemed to be a sale, conveyance, mortgage, grant,
bargain, encumbrance, pledge, assignment, or transfer within the meaning of this
Article 8.

         Section 8.4    LENDER'S RIGHTS.  Lender reserves the right to
condition the consent required hereunder upon a modification of the terms hereof
and on assumption of the Note, the Loan Agreement, this Security Instrument and
the Other Security Documents as so 

                                        - 37 -

modified by the proposed transferee, payment of all of Lender's expenses
incurred in connection with such transfer the proposed transferee's continued
compliance with the covenants set forth in Section 4.2, the approval by a Rating
Agency of the proposed transferee, hereof, or such other conditions as Lender
shall determine in its sole discretion to be in the interest of Lender.  Lender
shall not be required to demonstrate any actual impairment of its security or
any increased risk of default hereunder in order to declare the Debt immediately
due and payable upon Borrower's sale, conveyance, mortgage, grant, bargain,
encumbrance, pledge, assignment, or transfer of the Property without Lender's
consent.  This provision shall apply to every sale, conveyance, mortgage, grant,
bargain, encumbrance, pledge, assignment, or transfer of the Property regardless
of whether voluntary or not, or whether or not Lender has consented to any
previous sale, conveyance, mortgage, grant, bargain, encumbrance, pledge,
assignment, or transfer of the Property.

         Section 8.5    RESTRICTION ON FUNDAMENTAL CHANGES.  (a)  Without the
prior written consent of Lender, which consent may be withheld in the sole and
absolute discretion of Lender, Borrower and the REIT shall not enter into any
merger or consolidation with, or sell, lease, transfer or otherwise dispose of
any substantial assets to, any Person (as defined in the Loan Agreement) other
than Borrower, the REIT or a wholly owned subsidiary of Borrower or the REIT. 
Notwithstanding the foregoing, neither Borrower nor the REIT shall enter into
any arrangement, directly or indirectly, whereby Borrower or the REIT shall sell
or transfer any real property asset (in a single or multiple transaction) owned
by any of them in order then or thereafter to lease such property or lease
another real property asset that it intends to use for substantially the same
purpose as the real property asset being sold or transferred.

         (b)  Notwithstanding the foregoing, Borrower may enter into a merger
or consolidation, provided that following such merger or consolidation, Borrower
is the surviving entity of such merger or consolidation and the REIT or an
entity wholly owned and controlled by the REIT (i) is the sole general partner
of Borrower, and (ii) owns at least a 51% economic ownership interest in
Borrower.

the Other Security Documents, in the event of any prepayment of the Debt
pursuant to the terms of Sections 3.3 or 3.6 hereof, no Prepayment Consideration
(defined in the Note) shall be due in connection therewith, but Borrower shall

         Section 10.3   DEFAULT INTEREST.  Borrower does hereby agree that upon
the occurrence of an Event of Default, Lender shall be entitled to receive and
Borrower shall pay interest on the entire principal amount outstanding of the
Note at a rate equal to the Default Rate (as defined in the Note).  The Default
Rate shall be computed (i) for all Events of Default which can be cured by the
payment of a sum of money, from the date upon which such payment was due, and
(ii) for all other Events of Default, from the occurrence of the Event of
Default until, for all Events of Default, the earlier of the date upon which the
Event of Default is cured or the date upon which the Debt is paid in full. 
Interest calculated at the Default Rate shall be added to the Debt, and shall be
deemed secured by this Security Instrument.  This clause, however, shall not be
construed as an agreement or privilege to extend the date of the payment of the
Debt, nor as a waiver of any other right or remedy accruing to Lender by reason
of the occurrence of any Default or Event of Default.

         Section 11.1   REMEDIES.  Upon the occurrence of any Event of Default,
Borrower agrees that Lender may take such action, without notice or demand, as
it deems advisable to protect and enforce its rights against Borrower and in and
to the Property, including, but not limited to, the following actions, each of
which may be pursued concurrently or otherwise, at such time and in such order

    of the Debt;

         (h)  subject to any applicable law, the license granted to Borrower
    under Section 1.2 shall automatically be revoked and Lender may enter into

    Borrower to vacate and surrender possession of the Property to Lender or to
    such receiver and, in default thereof, Borrower may be evicted by summary

    shall deem appropriate in its sole discretion after deducting therefrom all
    expenses (including reasonable attorneys' fees) incurred in connection with
    the aforesaid operations and all amounts necessary to pay the Taxes, Other
    Charges, insurance and other expenses in connection with the Property, as
    well as just and reasonable compensation for the services of Lender, its

    five (5) days prior to such action, shall constitute commercially
    reasonable notice to Borrower;

                   Agreement, this Security Instrument and the Other Security
                   Documents, including without limitation advances made by
                   Lender pursuant to the terms of this Security Instrument;

         (k)  surrender the Policies maintained pursuant to Article 3 hereof,
    collect the unearned Insurance Premiums and apply such sums as a credit on
    the Debt in such priority and proportion as Lender in its discretion shall
    deem proper, and in connection therewith, Borrower hereby appoints Lender
    as agent and attorney-in-fact (which is coupled with an interest and is
    therefore irrevocable) for Borrower to collect such Insurance Premiums;

         (l)  pursue such other remedies as Lender may have under applicable
    law and/or; 

         (m)  apply the undisbursed balance of any Net Proceeds Deficiency
    deposit, together with interest thereon, to the payment of the Debt in such
    order, priority and proportions as Lender shall deem to be appropriate in
    its discretion.

In the event of a sale, by foreclosure, power of sale, or otherwise, of less
than all of the Property, this Security Instrument shall continue as a lien and
security interest on the remaining portion of the Property unimpaired and
without loss of priority.  Notwithstanding the provisions of this Section 11.1
to the contrary, if any Event of Default as described in clause (i) or (ii) of
Subsection 10.1(g) shall occur, the entire unpaid Debt shall be automatically
due and payable, without any further notice, demand or other action by Lender.

         Section 11.2   APPLICATION OF PROCEEDS.  The purchase money, proceeds
and avails of any disposition of the Property, or any part thereof, or any other
sums collected by Lender pursuant to the Note, the Loan Agreement, this Security
Instrument or the Other Security Documents, may be applied by Lender to the
payment of the Debt in such priority and proportions as Lender in its discretion
shall deem proper.

         Section 11.3   RIGHT TO CURE DEFAULTS.  Upon the occurrence of any
Default or Event of Default or if Borrower fails to make any payment or to do
any act as herein provided, Lender may, but without any obligation to do so and
without notice to or demand on Borrower and without releasing Borrower from any
obligation hereunder, make or do the same in such manner and to such extent as
Lender may deem necessary to protect the security hereof.  Lender is authorized
to enter upon the Property for such purposes, or appear in, defend, or bring any
action or proceeding to protect its interest in the Property or to foreclose
this Security Instrument or collect the Debt, and the cost and expense thereof
(including reasonable attorneys' fees to the extent permitted by law), with
interest as provided in this Section 11.3, shall constitute a portion of the
Debt and shall be due and payable to Lender upon demand.  All such costs and
expenses incurred by Lender in remedying such Default or Event of Default or
such failed payment or act or in appearing in, 

                                        - 45 -


<PAGE>

defending, or bringing any such action or proceeding shall bear interest at the
Default Rate, for the period after notice from Lender that such cost or expense
was incurred to the date of payment to Lender.  All such costs and expenses
incurred by Lender together with interest thereon calculated at the Default Rate
shall be deemed to constitute a portion of the Debt and be secured by this
Security Instrument and the Other Security Documents and shall be immediately
due and payable upon demand by Lender therefor.

         Section 11.4   ACTIONS AND PROCEEDINGS.  Lender has the right to
appear in and defend any action or proceeding brought with respect to the
Property and to bring any action or proceeding, in the name and on behalf of
Borrower, which Lender, in its discretion, decides should be brought to protect
its interest in the Property.

         Section 11.5   RECOVERY OF SUMS REQUIRED TO BE PAID.  Lender shall
have the right from time to time to take action to recover any sum or sums which
constitute a part of the Debt as the same become due, without regard to whether
or not the balance of the Debt shall be due, and without prejudice to the right
of Lender thereafter to bring an action of foreclosure, or any other action, for
a default or defaults by Borrower existing at the time such earlier action was
commenced.

         Section 11.6   EXAMINATION OF BOOKS AND RECORDS.  At Borrower's sole
cost and expense, Lender, its agents, accountants and attorneys shall have the
right to examine and inspect the records, books, management and other papers of
Borrower and its affiliates which reflect upon their financial condition
(including, without limitation, leases, statements, bills and invoices), at the
Property or at the principal place of business of Borrower, its affiliates where
the books and records are located.  Lender and its agents shall have the right
to make copies and extracts from the foregoing records and other papers.  In
addition, Lender, its agents, accountants and attorneys shall have the right to
examine, copy and audit the books and records of Borrower and its affiliates 
pertaining to the income, expenses and operation of the Property during
reasonable business hours at any office of Borrower, its affiliates where the
books and records are located.  This Section 11.6 shall apply throughout the
term of the Note and without regard to whether a Default or Event of Default has
occurred or is continuing.

         Section 11.7   OTHER RIGHTS, ETC.  (a)  The failure of Lender to
insist upon strict performance of any term hereof shall not be deemed to be a
waiver of any term of this Security Instrument.  Borrower shall not be relieved
of Borrower's obligations hereunder by reason of (i) the failure of Lender to
comply with any request of Borrower to take any action to foreclose this
Security Instrument or otherwise enforce any of the provisions hereof or of the
Note, the Loan Agreement or the Other Security Documents, (ii) the release,
regardless of consideration, of the whole or any part of the Property, or of any
person liable for the Debt or any portion thereof, or (iii) any agreement or
stipulation by Lender extending the time of payment or otherwise modifying or
supplementing the terms of the Note, the Loan Agreement, this Security
Instrument or the Other Security Documents.

<PAGE>

         (b)  It is agreed that the risk of loss or damage to the Property is
on Borrower, and Lender shall have no liability whatsoever for decline in value
of the Property, for failure to maintain the Policies, or for failure to
determine whether insurance in force is adequate as to the amount of risks
insured.  Possession by Lender shall not be deemed an election of judicial
relief, if any such possession is requested or obtained, with respect to any
Property or collateral not in Lender's possession.

         (c)  Lender may resort for the payment of the Debt to any other
security held by Lender in such order and manner as Lender, in its discretion,
may elect.  Lender may take action to recover the Debt, or any portion thereof,
or to enforce any covenant hereof without prejudice to the right of Lender
thereafter to foreclose this Security Instrument.  The rights of Lender under
this Security Instrument shall be separate, distinct and cumulative and none
shall be given effect to the exclusion of the others.  No act of Lender shall be
construed as an election to proceed under any one provision herein to the
exclusion of any other provision.  Lender shall not be limited exclusively to
the rights and remedies herein stated but shall be entitled to every right and
remedy now or hereafter afforded at law or in equity.

         Section 11.8   RIGHT TO RELEASE ANY PORTION OF THE PROPERTY.  Lender
may release any portion of the Property for such consideration as Lender may
require without, as to the remainder of the Property, in any way impairing or
affecting the lien or priority of this Security Instrument, or improving the
position of any subordinate lienholder with respect thereto, except to the
extent that the obligations hereunder shall have been reduced by the actual
monetary consideration, if any, received by Lender for such release, and may
accept by assignment, pledge or otherwise any other property in place thereof as
Lender may require without being accountable for so doing to any other
lienholder.  This Security Instrument shall continue as a lien and security
interest in the remaining portion of the Property.

         Section 11.9   VIOLATION OF LAWS.  If the Property is not in
compliance with Applicable Laws, Lender may impose additional requirements upon
Borrower in connection herewith including, without limitation, monetary reserves
or financial equivalents.

         Section 11.10  RECOURSE AND CHOICE OF REMEDIES.  Notwithstanding any
other provision of this Security Instrument, Lender and other Indemnified
Parties (defined in Section 13.1 below) are entitled to enforce the obligations
of Borrower contained in Sections 13.2, 13.3 and 13.4 without first resorting to
or exhausting any security or collateral and without first having recourse to
the Note or any of the Property, through foreclosure or acceptance of a deed in
lieu of foreclosure or otherwise, and in the event Lender commences a
foreclosure action against the Property, Lender is entitled to pursue a
deficiency judgment with respect to such obligations against Borrower.  The
liability of Borrower is not limited to the original principal amount of the
Note.  Notwithstanding the foregoing, nothing herein shall inhibit or prevent
Lender from foreclosing pursuant to this Security Instrument or exercising any
other rights and remedies pursuant to the Note, the Loan Agreement, this 

                                        - 47 -

Security Instrument and the Other Security Documents, whether simultaneously
with foreclosure proceedings or in any other sequence.  A separate action or
actions may be brought and prosecuted against Borrower, whether or not action is
brought against any other person or entity or whether or not any other person or
entity is joined in the action or actions.  In addition, Lender shall have the
right but not the obligation to join and participate in, as a party if it so
elects, any administrative or judicial proceedings or actions initiated in
connection with any matter addressed in Article 12 or Section 13.4.

         Section 11.11  RIGHT OF ENTRY.  Lender and its agents shall have the
right to enter and inspect the Property at all reasonable times, including,
without limitation, the right to enter and inspect in order to conduct an
appraisal of the Property.  This Section 11.11 shall apply throughout the term
of the Note and without regard to whether a Default or Event of Default has
occurred or is continuing.

                             ARTICLE 18 - APPLICABLE LAW

         SECTION 18.1   CHOICE OF LAW.  THIS SECURITY INSTRUMENT SHALL BE
DEEMED TO BE A CONTRACT ENTERED INTO PURSUANT TO THE LAWS OF THE STATE OF NEW
YORK AND SHALL IN ALL RESPECTS BE GOVERNED, CONSTRUED, APPLIED AND ENFORCED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, PROVIDED HOWEVER, THAT WITH
RESPECT TO THE CREATION, PERFECTION, PRIORITY AND ENFORCEMENT OF THE LIEN OF
THIS SECURITY INSTRUMENT, AND THE DETERMINATION OF DEFICIENCY JUDGMENTS, THE
LAWS OF THE STATE WHERE THE PROPERTY IS LOCATED SHALL APPLY.

         Section 18.2   USURY LAWS.  This Security Instrument and the Note are
subject to the express condition that at no time shall Borrower be obligated or
required to pay interest on the Debt at a rate which could subject the holder of
the Note to either civil or criminal liability as a result of being in excess of
the maximum interest rate which Borrower is permitted by applicable law to
contract or agree to pay.  If by the terms of this Security Instrument or the
Note, Borrower is at any time required or obligated to pay interest on the Debt
at a rate in excess of such maximum rate, the rate of interest under the
Security Instrument and the Note shall be deemed to be immediately reduced to
such maximum rate and the interest payable shall be computed at such maximum
rate and all prior interest payments in excess of such maximum rate shall be
applied and shall be deemed to have been payments in reduction of the principal
balance of the Note.  All sums paid or agreed to be paid to Lender for the use,
forbearance, or detention of the Debt shall, to the extent permitted by
applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of the Note until payment in full so that the rate or amount of
interest on account of the Debt does not exceed the maximum lawful rate of
interest from time to time in effect and applicable to the Debt for so long as
the Debt is outstanding.

powers and remedies provided in this Security Instrument may be exercised only
to the extent that the exercise thereof does not violate any applicable
provisions of law and are intended to be limited to the extent necessary so that
they will not render this Security Instrument invalid, unenforceable or not
entitled to be recorded, registered or filed under the provisions of any
applicable law.  If any term of this Security Instrument or any application
thereof shall be invalid or unenforceable, the remainder of this Security
Instrument and any other application of the term shall not be affected thereby.

                        ARTICLE 23 - STATE SPECIFIC PROVISIONS


         Section 23.1   TRUST FUND.  Pursuant to Section 13 of the New York
Lien Law, Borrower shall receive the advances secured hereby and shall hold the
right to receive the advances as a trust fund to be applied first for the
purpose of paying the cost of any improvement and shall apply the advances first
to the payment of the cost of any such improvement on the Property before using
any part of the total of the same for any other purpose.

         Section 23.2   COMMERCIAL PROPERTY.  Borrower represents that this
Security Instrument does not encumber real property principally improved or to
be improved by one or more structures containing in the aggregate not more than
six residential dwelling units, each having its own separate cooking facilities.

         Section 23.3   INSURANCE.  The provisions of subsection 4 of Section
254 of the New York Real Property Law covering the insurance of buildings
against loss by fire shall not apply to this Security Instrument.  In the event
of any conflict, inconsistency or ambiguity between the provisions of
Section 3.3 hereof and the provisions of subsection 4 of Section 254 of the New
York Real Property Law covering the insurance of buildings against loss by fire,
the provisions of Section 3.3 shall control.

         Section 23.4   LEASES.  Lender shall have all of the rights against
lessees of the Property set forth in Section 291-f of the Real Property Law of
New York.

         Section 23.5   TRANSFER TAXES.

         (a)  In the event of any sale or transfer of the Property, or any part
thereof, including any sale or transfer by reason of foreclosure of this
Security Instrument or any prior or subordinate mortgage or by deed in lieu of
any such foreclosure, Borrower shall timely and duly complete, execute and
deliver to Lender all forms and supporting documentation required by any taxing
authority to estimate and fix any tax payable by reason of such sale or transfer
or recording of the deed evidencing such sale or transfer, including any New
York State Real Estate Transfer Tax payable pursuant to Article 31 of the New
York Tax Law and New York City Real Property Transfer Tax payable pursuant to
Chapter 21, Title 11 of the New York City Administrative Code (individually, a
"Transfer Tax" and collectively, the "Transfer Taxes").

         (b)  Borrower shall pay the Transfer Taxes that may hereafter become
due and payable with respect to any sale or transfer of the Property described
in this Article, and in default of such payment, Lender may pay the same and the
amount of such payment shall be added to the Debt secured hereby and, unless
incurred in connection with a foreclosure of this Security Instrument or deed in
lieu of such foreclosure, be secured by this Security Instrument.

                                        - 65 -


<PAGE>

         (c)  Borrower hereby irrevocably constitutes and appoints Lender as
its attorney-in-fact, coupled with an interest, to prepare and deliver any
questionnaire, statement, affidavit or tax return in connection with any
Transfer Tax applicable to any foreclosure or deed in lieu of foreclosure
described in this Article.

         (d)  Borrower shall indemnify and hold harmless Lender against (i) any
and all liability incurred by Lender for the payment of any Transfer Tax with
respect to any transfer of the Property, and (ii) any and all expenses incurred
by Lender in connection therewith including, without limitation, interest,
penalties and attorneys' fees.

         (e)  The obligation to pay the taxes and indemnify Lender under this
Article is a personal obligation of Borrower, whether or not Borrower is
personally obligated to pay the Debt secured by this Security Instrument, and
shall be binding upon and enforceable against the distributees, successors and
assigns of Borrower with the same force and effect as though each of them had
personally executed and delivered this Security Instrument, notwithstanding any
exculpation provision in favor of Borrower with respect to the payment of any
other monetary obligations under this Security Instrument.

         (f)  In the event that Borrower fails or refuses to pay a tax payable
by Borrower with respect to a sale or transfer by reason of a foreclosure of
this Security Instrument in accordance with this Article, the amount of the tax,
any interest or penalty applicable thereto and any other amount payable pursuant
to Borrower's obligation to indemnify Lender under this Article may, at the sole
option of Lender, be paid as an expense of the sale out of the proceeds of the
mortgage foreclosure sale.

         (g)  The provisions of this Article shall survive any transfer and the
delivery of the deed affecting such transfer.  Nothing in this Article shall be
deemed to grant to Borrower any greater rights to sell, assign or otherwise
transfer the premises than are expressly provided in Article 8 nor to deprive
Lender of any right to refuse to consent to any transaction referred to in this
Article.

         Section 23.6   STATUTORY CONSTRUCTION.  The clauses and covenants
contained in this Security Instrument that are construed by Section 254 of the
New York Real Property Law shall be construed as provided in those sections
(except as provided in Section 23.3).  The additional clauses and covenants
contained in this Security Instrument shall afford rights supplemental to and
not exclusive of the rights conferred by the clauses and covenants construed by
Section 254 and shall not impair, modify, alter or defeat such rights (except as
provided in Section 23.3), notwithstanding that such additional clauses and
covenants may relate to the same subject matter or provide for different or
additional rights in the same or similar contingencies as the clauses and
covenants construed by Section 254.  The rights of Lender arising under the
clauses and covenants contained in this Security Instrument shall be separate,
distinct and cumulative and none of them shall be in exclusion of the others. 
No act of Lender shall be construed as an election to proceed under any one
provision herein to the exclusion of any other provision, anything herein or
otherwise to the 

                                        - 66 -

under any contingency may be secured by this Security Instrument is the amount
set forth in the Recitals above.
