                     EMPLOYMENT AND NONCOMPETITION AGREEMENT

     This AMENDED AND RESTATED EMPLOYMENT AND NONCOMPETITION AGREEMENT
("Agreement") is made as of the 30th day of September, 1998 between Gerard
Nocera ("Executive") and SL Green Realty Corp., a Maryland corporation with its
principal place of business at 70 West 36th Street, New York, New York 10018
(the "Employer"), and amends and completely restates the Employment and

October, 1998 and, unless earlier terminated as provided herein, shall terminate
on the third anniversary of such date (the "Current Term"); PROVIDED, HOWEVER,
that Section 8 hereof shall survive the termination of this Agreement as
provided therein. The Current Term shall automatically be extended for
successive one-year periods (each a "Renewal Term"), unless either party shall
notify the other in writing at least six (6) months prior to the expiration of
the Current Term or the applicable Renewal Term of its intention not to renew
such Term. The period of Executive's employment hereunder consisting of the
Current Term and all Renewal Terms, if any, is herein referred to as the
"Employment Period"

          time and efforts to the performance of his duties under this
          Agreement, except as otherwise approved by the Board of Directors of
          the Employer; PROVIDED, HOWEVER, that nothing herein shall be
          interpreted to preclude Executive from (i) participating as an officer
          or director of, or advisor to, any charitable or other tax exempt
          organization or otherwise engaging in charitable, fraternal or trade
          group activities, (ii) acting as an officer of any subsidiary of the

          entities or business ventures, provided that he performs no management
          or similar role with respect to such entities or ventures and such
          investment does not violate Section 8 hereof.

          (c)  TRAVEL. In performing his duties hereunder, Executive shall be
          available for all reasonable travel as the needs of the Employer's
          business may require. Executive shall be based in the metropolitan

          Executive pursuant to Section 3(a), during the Employment Period,
          Executive shall be eligible to participate in any incentive

          of the Employer, subject to Executive's compliance with such criteria
          as the Employer's Board of Directors, in its sole discretion, may
          establish for Executive's participation in such plans from time to
          time. Any awards to Executive under such plans will be established by

          families, on the terms and subject to the conditions set forth in such
          plan. Nothing in this section shall limit the Employer's right to
          change, modify or terminate any benefit plan or program as it sees fit
          from time to time in the normal course of business.

          (f)  VACATIONS. Executive shall be entitled to reasonable paid
          vacations in accordance with the then regular procedures of the

          (g)  OTHER BENEFITS. During the Employment Period, the Employer shall
          provide to Executive such other benefits, including sick leave and the

          participate in such retirement or pension plans, as are made generally
          available to senior executive officers and employees of the Employer
          from time to time.

     4.   INDEMNIFICATION AND LIABILITY INSURANCE. The Employer agrees to
indemnify Executive to the extent permitted by applicable law with respect to
any actions commenced against Executive in his capacity as an officer or
director, or former officer or director, of the Employer or any affiliate
thereof for which he may serve in such capacity. The Employer also agrees to use
its best efforts to secure and maintain officers and directors liability
insurance providing coverage for Executive.

     5.   EMPLOYER'S POLICIES. Executive agrees to observe and comply with the
rules and regulations of the Employer as adopted by its Board of Directors from
time to time regarding the performance of his duties and to carry out and
perform orders, directions and policies communicated to him from time to time by
the Employer's Board of Directors.

     6.   TERMINATION. The Executive's employment hereunder may be terminated
under the following circumstances:

          (a)  TERMINATION BY THE EMPLOYER.

               (i)    DEATH. The Executive's employment hereunder shall
          terminate upon his death.

               (ii)   DISABILITY. If, in the reasonable good faith determination
          of the Board of Directors, as a result of the Executive's incapacity
          due to physical or mental illness or disability, the Executive shall
          have been incapable of performing his duties hereunder even with a
          reasonable accommodation on a full-time basis for the entire period of
          three consecutive months or any 90 days in a 180-day period, and
          within 30 days after written Notice of Termination (as defined in
          Section 6(c)) is given he shall not have returned to the performance
          of his duties hereunder on a full-time basis, the Employer may
          terminate the Executive's employment hereunder.

               (iii)  CAUSE. The Employer may terminate the Executive's
          employment hereunder for Cause, subject to the severance provisions
          specifically set forth in Section 7(b) and the arbitration provisions
          specifically set forth in Section 7(e). For purposes of the Agreement,
          "Cause" shall mean that the Board of Directors of the Employer
          concludes, in good faith and after reasonable investigation, that:

                      (A)   the Executive engaged in conduct which is a felony
               under the laws of the United States or any state or political
               subdivision thereof;

                      (B)   the Executive engaged in conduct constituting breach
               of fiduciary duty, gross negligence or willful misconduct
               relating to the Employer, fraud or dishonesty or willful or
               material misrepresentation relating to the business of the
               Employer;

                                        3
<Page>

                      (C)   the Executive breached his obligations or covenants
               under Section 8 of this Agreement in any material respect; or

                      (D)   the Executive failed to perform his duties hereunder
               in a manner and at a level reasonably satisfactory to the
               Employer more than 15 days after receiving notice from the
               Employer, which notice specifically identifies the manner in
               which he has failed so to perform.

               (iv)   WITHOUT CAUSE. Executive's employment hereunder may be
          terminated by the Employer at any time with or without Cause (as
          defined in Section 6(a)(iii) above), by a majority vote of all of the
          members of the Board of Directors of the Employer upon written notice
          to Executive, subject only to the severance provisions specifically
          set forth in Section 7(a) herein.

          (b)  TERMINATION BY THE EXECUTIVE.

               (i)    DISABILITY. The Executive may terminate his employment
          hereunder for Disability within the meaning of Section 6(a)(ii) above.

               (ii)   WITH GOOD REASON. Executive's employment hereunder may be
          terminated by Executive with Good Reason effective immediately by
          written notice to the Board of Directors of the Employer. For purposes
          of this Agreement, with "Good Reason" shall mean: (i) a failure of the
          Board of Directors of the Employer to elect Executive to offices with
          the same or substantially the same duties and responsibilities as set
          forth in Section 2; (ii) a material failure by the Employer to comply
          with the provisions of Section 3 or a material breach by the Employer
          of any other provision of this Agreement which has not been cured
          within thirty (30) days after notice of noncompliance, (specifying the
          nature of the noncompliance) has been given by the Executive to the
          Employer; or (iii) a Force Out (as such term is defined in Section
          6(d) below). Notwithstanding any provision of this Agreement to the
          contrary, with "Good Reason" shall not include any assignment of
          Executive to a position or office that has new or different duties,
          provided that such position or office is principally related to
          leasing, has a substantially similar level of responsibility to
          Executive's immediately preceding position or office and is
          commensurate with Executive's education, skills and experience.

          (c)  NOTICE OF TERMINATION. Any termination of the Executive's
          employment by the Employer or by the Executive (other than termination
          pursuant to subsection (a)(1) hereof) shall be communicated by written
          Notice of Termination to the other party hereto in accordance with
          Section 11 of this Agreement. For purposes of this Agreement, a
          "Notice of Termination" shall mean a notice which shall indicate the
          specific termination provision in this Agreement relied upon and, as
          applicable, shall set forth in reasonable detail the fact and
          circumstances claimed to provide a basis for termination of the
          Executive's employment under the provision so indicated.

          after the effective date of the initial public offering of the
          Employer's Common Stock ("IPO") if:

                      (A)   any Person, together with all "affiliates" and
               "associates" (as such terms are defined in Rule 12b-2 under the
               Securities Exchange Act of 1934 (the "Exchange Act")) of such
               Person, shall become the "beneficial owner" (as such term is
               defined in Rule 13d-3 under the Exchange Act), directly or
               indirectly, of securities of the Employer representing 40% or
               more of either (A) the combined voting power of the Employer's
               then outstanding securities having the right to vote in an
               election of the Employer's Board of Directors ("Voting
               Securities") or (B) the then outstanding shares of all classes of
               stock of the Employer (in either such case other than as a result
               of the acquisition of securities directly from the Employer); or

                      (B)   individuals who, as of the date of the closing of
               the IPO, constitute the Employer's Board of Directors (the
               "Incumbent Directors") cease for any reason, including, without
               limitation, as a result of a tender offer, proxy contest, merger
               or similar transaction, to constitute at least a majority of the
               Employer's Board of Directors, provided that any person becoming
               a director of the Employer subsequent to the closing of the IPO
               whose election or nomination for election was approved by a vote
               of at least a majority of the Incumbent Directors shall, for
               purposes of this Agreement, be considered an Incumbent Director;
               or

                      (C)   the stockholders of the Employer shall approve (1)
               any consolidation or merger of the Employer or any subsidiary
               where the stockholders of the Employer, immediately prior to the
               consolidation or merger, would not, immediately after the
               consolidation or merger, beneficially own (as such term is
               defined in Rule l3d-3 under the Exchange Act), directly or
               indirectly, shares representing in the aggregate at least 50% of
               the voting shares of the corporation issuing cash or securities
               in the consolidation or merger (or of its ultimate parent
               corporation, if any), (2) any sale, lease, exchange or other
               transfer (in one transaction or a series of transactions
               contemplated or arranged by any party as a single plan) of all or
               substantially all of the assets of the Employer or (3) any plan
               or proposal for the liquidation or dissolution of the Employer;

               Notwithstanding the foregoing, a "Change-in-Control" shall not be
          deemed to have occurred for purposes of the foregoing clause (A)
          solely as the result of an acquisition of securities by the Employer
          which, by reducing the number of shares of stock or other Voting
          Securities outstanding, increases (x) the proportionate number of
          shares of stock of the Employer beneficially owned by

                                        5
<Page>

          any Person to 40% or more of the shares of stock then outstanding or
          (y) the proportionate voting power represented by the Voting
          Securities beneficially owned by any Person to 40% or more of the
          combined voting power of all then outstanding Voting Securities;
          PROVIDED, HOWEVER, that if any Person referred to in clause (x) or (y)
          of this sentence shall thereafter become the beneficial owner of any
          additional stock of the Employer or other Voting Securities (other
          than pursuant to a share split, stock dividend, or similar
          transaction), then a "Change-in-Control" shall be deemed to have
          occurred for purposes of the foregoing clause (A). In addition,
          notwithstanding the foregoing, a "Change-in-Control" shall not be
          deemed to have occurred for purposes of the foregoing clause (A) if
          (i) Stephen L. Green continues to serve as Chief Executive Officer or
          the equivalent of any surviving entity, and (ii) the proportionate
          number of shares of stock of the Employer beneficially owned, or the
          proportionate voting power represented by the Voting Securities
          beneficially owned, by any Person described in such clause (A) does
          not exceed 49%.

               (ii)   A "Force Out" shall be deemed to have occurred in the
          event of a Change-In-Control followed by:

                      (A)   a change in duties, responsibilities, status or
               positions with the Employer, which, in Executive's reasonable
               judgment, does not represent a promotion from or maintaining of
               Executive's duties, responsibilities, status or positions as in
               effect immediately prior to the Change-In-Control, or any removal
               of Executive from or any failure to reappoint or reelect
               Executive to such positions, except in connection with the
               termination of Executive's employment for Cause, disability,
               retirement or death;

                      (B)   a reduction by the Employer in Executive's Base
               Salary as in effect immediately prior to the Change-In-Control;

                      (C)   the failure by the Employer to continue in effect
               any of the benefit plans in which Executive is participating at
               the time of the Change-In-Control of the Employer (unless
               Executive is permitted to participate in any substitute benefit
               plan with substantially the same terms and to the same extent and
               with the same rights as Executive had with respect to the benefit
               plan that is discontinued) other than as a result of the normal
               expiration of any such benefit plan in accordance with its terms
               as in effect at the time of the Change-In-Control, or the taking
               of any action, or the failure to act, by the Employer which would
               adversely affect Executive's continued participation in any of
               such benefit plans on at least as favorable a basis to Executive
               as was the case on the date of the Change-In-Control or which
               would materially reduce Executive's benefits in the future under
               any of such benefit plans or deprive Executive of any material
               benefits enjoyed by Executive at the time of the
               Change-In-Control; PROVIDED, HOWEVER, that any such action or
               inaction on the part of the Employer, including any modification,
               cancellation or

                                        6
<Page>

               termination of any benefits plan, undertaken in order to maintain
               such plan in compliance with any federal, state or local law or
               regulation governing benefits plans, including, but not limited
               to, the Employment Retirement Income Security Act of 1974, shall
               not constitute a Force Out for the purposes of this Agreement.

                      (D)   the Employer's requiring Executive to be based in an
               office located beyond a reasonable commuting distance from
               Executive's residence immediately prior to the Change-In-Control,
               except for required travel relating to the Employer's business to
               an extent substantially consistent with the business travel
               obligations which Executive undertook on behalf of the Employer
               prior to the Change-In-Control;

                      (E)   the failure by the Employer to obtain from any
               successor to the Employer an agreement to be bound by this
               Agreement pursuant to Section 14 hereof; or

               (iii)  "Person" shall have the meaning used in Sections 13(d) and
          14(d) of the Exchange Act; provided however, that the term "Person"
          shall not include (A) any current partner of SL Green Operating
          Partnership, L.P., any stockholder or employee of the Employer on the
          date hereof or any estate or member of the immediate family of such a
          partner, stockholder or employee, or (B) the Employer, any of its
          subsidiaries, or any trustee, fiduciary or other person or entity
          holding securities under any employee benefit plan of the Employer or
          any of its subsidiaries.

     7.   COMPENSATION UPON TERMINATION OR DURING DISABILITY.

          (a)  TERMINATION WITHOUT CAUSE OR WITH GOOD REASON. If (i) Executive
          is terminated without Cause pursuant to Section 6(a)(iv) above, or
          (ii) Executive shall terminate his employment hereunder with Good
          Reason pursuant to Section (6)(b)(ii) above, then the Employment
          Period shall terminate as of the effective date set forth in the
          written notice of such termination (the "Termination Date") and
          Executive shall be entitled to the following benefits:

               (i)    The Employer shall continue to pay Executive's Base Salary
          for the remaining term of the Employment Period after the date of
          Executive's termination, or, if such termination occurs in connection
          with or after a Change-in-Control, for three years, whichever period
          is longer, at the rate in effect on the date of his termination and on
          the same periodic payment dates as payment would have been made to
          Executive had the Employment Period not been terminated;

               (ii)   For the remaining term of the Employment Period, or, if
          such termination occurs in connection with or after a
          Change-in-Control, for three years, whichever period is longer,
          Executive shall continue to receive all benefits described in Section
          3 existing on the date of termination, including, but not limited to,
          any bonuses and incentive compensation described in Section 3 of this

                                        7
<Page>

          Agreement, subject to the terms and conditions upon which such
          benefits may be offered. For purposes of the application of such
          benefits, Executive shall be treated as if he had remained in the
          employ of the Employer with a Base Salary at the rate in effect on the
          date of termination;

               (iii)  For purposes of any stock option plan of the Employer, (x)
          Executive shall be treated as if he had remained in the employ of the
          Employer for the remaining term of the Employment Period after the
          date of Executive's termination, or for one year, whichever period is
          longer, so that Executive may exercise any exercisable options and
          Executive's other rights shall continue to vest during the remaining
          term of the Employment Period with respect to any options previously
          granted under such plans, except as otherwise provided in such plans,
          and (y) if such termination occurs in connection with or after a
          Change-in-Control, any stock options and any other rights of Executive
          (including restricted stock awards) shall become fully vested and
          immediately exercisable upon such termination;

               (iv)   Nothing herein shall be deemed to obligate Executive to
          seek other employment in the event of any such termination and any
          amounts earned or benefits received from such other employment will
          not serve to reduce in any way the amounts and benefits payable in
          accordance herewith; and

               (v)    If in the opinion of tax counsel selected by the Executive
          and reasonably acceptable to the Employer, the Executive has or will
          receive any compensation or recognize any income (whether or not
          pursuant to this Agreement or any plan or other arrangement of the
          Employer and whether or not the Employment Period or the Executive's
          employment with the Employer has terminated) which will constitute an
          "excess parachute payment" within the meaning of Section 280G(b)(1) of
          the Internal Revenue Code (the "Code") (or for which a tax is
          otherwise payable under Section 4999 of the Code or any successor
          provision thereto), then the Employer shall pay the Executive an
          additional amount (the "Additional Amount") equal to the sum of (i)
          all taxes payable by the Executive under Section 4999 of the Code with
          respect to all such excess parachute payments and any such Additional
          Amount, plus (ii) all federal, state and local income taxes payable by
          Executive with respect to any such Additional Amount. Any amounts
          payable pursuant to this paragraph (v) shall be paid by the Employer
          to the Executive within 30 days of each written request therefor made
          by the Executive.

          (b)  TERMINATION FOR CAUSE OR WITHOUT GOOD REASON. If Executive is
          terminated for Cause pursuant to Section 6(a)(iii) above, or if
          Executive voluntarily terminates his employment hereunder without Good
          Reason pursuant to Section 6(b)(ii) above, then the Employment Period
          shall terminate as of the effective date set forth in the written
          notice of such termination (the "Termination Date") and any
          outstanding stock options held by Executive shall expire in accordance
          with the terms of the stock option plan or option agreement under

                                        8
<Page>

          which the stock options were granted. Executive shall be entitled to
          receive the following benefits:

               (i)    If (A) Executive is terminated for Cause pursuant to
          Section 6(a)(iii)(A), (B) or (C) above (regardless of whether he
          submits a claim of lack of Cause to arbitration pursuant to
          Section 7(e) herein), (B) Executive is terminated for Cause pursuant
          to Section 6(a)(iii)(D) above and does not submit a claim of lack of
          Cause to arbitration pursuant to Section 7(e) herein, or (C) Executive
          voluntarily terminates his employment hereunder without Good Reason
          pursuant to Section 6(b)(ii) above, then Executive shall be entitled
          to receive only his Base Salary at the rate then in effect until the
          Termination Date.

                      (ii)  If Executive is terminated for Cause pursuant to
               Section 6(a)(iii)(D) above and submits a claim of lack of Cause
               to arbitration pursuant to Section 7(e) herein, then, subject to
               Executive's repayment obligation under Section 7(e)(ii)(B),
               Executive shall be entitled to receive 80% of his Base Salary at
               the rate then in effect until the earlier of either the date one
               year after the Termination Date or the date of the arbitrator's
               final determination.

          (c)  TERMINATION BY REASON OF DEATH. If Executive's employment
          terminates due to his death, the Employer shall pay Executive's Base
          Salary for a period of six months from the date of his death, or such
          longer period as the Employer's Board of Directors may determine, to
          Executive's estate or to a beneficiary designated by Executive in
          writing prior to his death. Any unexercised or unvested stock options
          shall remain exercisable or vest upon Executive's death only to the
          extent provided in the applicable option plan and option agreements.

          (d)  TERMINATION BY REASON OF DISABILITY. In the event that
          Executive's employment terminates due to his disability as defined in
          Section 6(a)(ii) above, Executive shall be entitled to be paid his
          Base Salary until the later of such time when (i) the period of
          disability or illness (whether or not the same disability or illness)
          shall exceed 180 consecutive days during the Employment Period and
          (ii) Executive becomes eligible to receive benefits under a
          comprehensive disability insurance policy obtained by the Employer
          (the "Disability Period"). Following the expiration of the Disability
          Period, the Employer may terminate this Agreement upon written notice
          of such termination. Any unexercised or unvested stock options shall
          remain exercisable or vest upon such termination only to the extent
          provided in the applicable option plan and option agreements.

          (e)  ARBITRATION IN THE EVENT OF A DISPUTE REGARDING THE NATURE OF
          TERMINATION. In the event that the Executive's employment is
          terminated by the Employer for Cause or by Executive for Good Reason,
          and either party contends that such Cause or Good Reason did not
          exist, the parties agree to submit such claim to arbitration before
          the American Arbitration Association ("AAA"), and Executive hereby
          agrees to submit to any such dispute to arbitration pursuant to the
          terms of this Section 7(e). In such a proceeding, the only issue
          before the

                                        9
<Page>

          arbitrator will be whether Executive's employment was in fact
          terminated for Cause or for Good Reason, as the case may be.

               (i)    AWARDS IN FAVOR OF THE EXECUTIVE. If the arbitrator
          determines that Executive's employment was terminated by the Employer
          without Cause or was terminated by Executive for Good Reason, the only
          remedy that the arbitrator may award is an amount equal to the
          severance payments specified in Section 7(a), the costs of
          arbitration, and Executive's attorneys' fees. In cases where an award
          is granted to an Executive who was terminated for Cause pursuant to
          Section 6(a)(iii)(D) above, such arbitration award shall be reduced by
          the amount of Base Salary already paid by the Employer pursuant to
          Section 7(b)(ii) above.

               (ii)   AWARDS IN FAVOR OF THE EMPLOYER.

                      (A)   If the arbitrator finds that Executive's employment
               was terminated by the Employer for Cause pursuant to Section
               6(a)(iii)(A), (B), (C) or (D) above, or by the Executive without
               Good Reason, the arbitrator will be without authority to award
               Executive anything, the parties will each be responsible for
               their own attorneys' fees, and the costs of arbitration will be
               paid 50% by Executive and 50% by the Employer.

                      (B)   In addition, if the arbitrator finds that the
               Executive's employment was terminated for Cause pursuant to
               Section 6(a)(iii)(D) above, Executive must promptly reimburse the
               Employer for the full amount of any Base Salary paid by the
               Employer with respect to periods after the Termination Date
               pursuant to Section 7(b)(ii) above.

     8.   CONFIDENTIALITY; PROHIBITED ACTIVITIES. The Executive and the Employer
recognize that due to the nature of his employment and relationship with the
Employer, the Executive has access to and develops confidential business
information, proprietary information, and trade secrets relating to the business
and operations of the Employer. The Executive acknowledges that such information
is valuable to the business of the Employer, and that disclosure to, or use for
the benefit of, any person or entity other than the Employer, would cause
irreparable damage to the Employer. The Executive further acknowledges that his
duties for the Employer include the duty to develop and maintain client,
customer, employee, and other business relationships on behalf of the Employer;
and that access to and development of those close business relationships for the
Employer render his services special, unique and extraordinary. In recognition
that the good will and business relationships described herein are valuable to
the Employer, and that loss of or damage to those relationships would destroy or
diminish the value of the Employer, the Executive agrees as follows:

          (a)  CONFIDENTIALITY. During the term of this Agreement (including any
          renewals), and at all times thereafter, the Executive shall maintain
          the confidentiality of all confidential or proprietary information of
          the Employer ("Confidential Information"), and, except in furtherance
          of the business of the Employer, he shall not directly or indirectly
          disclose any such information to any person or entity; nor shall he
          use Confidential Information for any purpose except

                                       10
<Page>

          for the benefit of the Employer. For purposes of the Agreement,
          "Confidential Information" includes, without limitation: client or
          customer lists, identities, contacts, business and financial
          information; investment strategies; pricing information or policies,
          fees or commission arrangements of the Employer; marketing plans,
          projections, presentations or strategies of the Employer; financial
          and budget information of the Employer; new personnel acquisition
          plans; and all other business related information which has not been
          publicly disclosed by the Employer. This restriction shall apply
          regardless of whether such Confidential Information is in written,
          graphic, recorded, photographic, data or any machine readable form or
          is orally conveyed to, or memorized by, the Executive. The Executive
          further agrees that, during the Employment Period and at all times
          thereafter, he shall keep confidential and shall not release, use or
          disclose without prior written permission of the Employer, all
          Confidential Information developed by him on behalf of the Employer or
          provided to him by the Employer, excepting only such information as
          was already known to him prior to the commencement of his employment
          by the Employer or such information as is already known to the public.

          (b)  PROHIBITED ACTIVITIES. Because Executive's services to the
          Employer are essential and because Executive has access to the
          Employer's Confidential Information, Executive covenants and agrees
          that (i) during the Employment Period, (ii) in the event that this
          Agreement is terminated by the Employer for Cause or by the Executive
          other than for Good Reason, during the one-year period following the
          date of such termination, and (iii) solely for purposes of paragraph
          (vi) below, during the five-year period following the date on which
          Executive's employment terminates for any reason, Executive will not,
          without the prior written consent of the Board of Directors of the
          Employer which shall include the unanimous consent of the Directors
          who are not officers of the Employer, directly or indirectly
          (individually, or through or on behalf of another entity as owner,
          partner, agent, employee, consultant, or in any other capacity):

               (i)    engage, participate or assist, as an owner, partner,
          employee, consultant, director, officer, trustee or agent, in any
          business that engages or attempts to engage, directly or indirectly,
          in any material acquisition, development, construction, operation,
          management or leasing of any commercial real estate property:

                      (A)   anywhere in the five boroughs of New York City,
               regardless of whether such business is publicly or privately
               held;

                      (B)   anywhere in the New York City metropolitan area, if
               such business or any of its affiliates (within the meaning of the
               Securities Act of 1933) has issued any class of publicly-traded
               securities;

                      (C)   anywhere in the New York City metropolitan area,
               regardless of whether such business is publicly or privately
               held, if such

                                       11
<Page>

               business engages in the commercial real estate business in any
               county in which the Employer also engages in the commercial real
               estate business.

               For purposes of this subsection, the New York City metropolitan
          area includes each borough of New York City; Nassau, Orange, Putnam,
          Rockland, Suffolk and Westchester Counties in the State of New York;
          Bergen, Essex, Hudson, Hunterdon, Mercer, Middlesex, Monmouth, Morris,
          Passaic, Somerset, Sussex, Union and Warren Counties in the State of
          New Jersey; and Fairfield County in the State of Connecticut);

               (ii)   seek, solicit, or engage in any attempt to establish for
          himself or for any other person or entity, a business relationship
          with any person or entity who was a client or customer of the
          Employer, or who was solicited to become a client or customer of the
          Employer, during the Employment Period ("Employer Clients");

               (iii)  engage in any activity to interfere with, disrupt or
          damage the business of the Employer, or its relationships with any
          Employer Client, employee, supplier or other business relationship;

               (iv)   engage in business with, or provide advice or services to,
          any Employer Client solicited by the Executive in breach of Section 8
          of this Agreement (whether or not such services are compensated);

               (v)    receive, or cause any other person or entity to receive,
          any compensation, consideration, or income, in any form, from any
          Employer Client solicited by him in breach of Section 8 of this
          Agreement; or

               (vi)   solicit, encourage, or engage in any activity to induce
          any Employee of the Employer to terminate employment with the
          Employer, or to become employed by, or to enter into a business
          relationship with, any other person or entity. For purposes of this
          subsection, the term Employee means any individual who is an employee
          of or consultant to the Employer (or any affiliate) during the
          six-month period prior to Executive's last day of employment.

               (c)    OPTION PROPERTY. Notwithstanding anything contained herein
          to the contrary, Executive is not prohibited by this Section 8 from
          (i) maintaining his or her investment in any Option Property (as such
          term is defined in the Employer's final prospectus relating to the
          IPO) or in any asset listed in the Employer's final prospectus
          relating to the IPO under the caption "The Properties - Assets Not
          Being Transferred to the Company" or (ii) from making investments in
          any entity that engages, directly or indirectly, in the acquisition,
          development, construction, operation, management or leasing of office
          real estate properties, regardless of where they are located, if the
          shares or other ownership interests of such entity are publicly traded
          and Executive's aggregate investment in such entity constitutes less
          than one percent (1%) of the equity ownership of such entity.

                                       12
<Page>

          (d)  EMPLOYER PROPERTY. The Executive acknowledges that all originals
          and copies of materials, records and documents generated by him or
          coming into his possession during his employment by the Employer are
          the sole property of the Employer ("Employer Property"). During his
          employment, and at all times thereafter, the Executive shall not
          remove, or cause to be removed, from the premises of the Employer,
          copies of any record, file, memorandum, document, computer related
          information or equipment, or any other item relating to the business
          of the Employer, except in furtherance of his duties under the
          Agreement. When the Executive terminates his employment with the
          Employer, or upon request of the Employer at any time, the Executive
          shall promptly deliver to the Employer all originals and copies of
          Employer Property in his possession or control and shall not retain
          any originals or copies in any form.

          (e)  NO DISPARAGEMENT. Following termination of the Executive's
          employment for any reason, the Executive shall not disclose or cause
          to be disclosed any negative, adverse or derogatory comments or
          information about (i) the Employer and its parent, affiliates or
          subsidiaries, if any; (ii) any product or service provided by the
          Employer and its parent, affiliates or subsidiaries, if any; or (iii)
          the Employer's and its parent's, affiliates' or subsidiaries'
          prospects for the future.

          (f)  REMEDIES. The Executive declares that the foregoing limitations
          in Sections 8(a) through 8(f) above are reasonable and necessary for
          the adequate protection of the business and the goodwill of the
          Employer. If any restriction contained in this Section 8 shall be
          deemed to be invalid, illegal or unenforceable by reason of the
          extent, duration or scope thereof, or otherwise, then the court making
          such determination shall have the right to reduce such extent,
          duration, scope, or other provisions hereof to make the restriction
          consistent with applicable law, and in its reduced form such
          restriction shall then be enforceable in the manner contemplated
          hereby. In the event that the Executive breaches any of the promises
          contained in this Section 8, the Executive acknowledges that the
          Employer's remedy at law for damages will be inadequate and that the
          Employer will be entitled to specific performance, a temporary
          restraining order or preliminary injunction to prevent the Executive's
          prospective or continuing breach and to maintain the status quo. The
          existence of this right to injunctive relief, or other equitable
          relief, or the Employer's exercise of any of these rights, shall not
          limit any other rights or remedies the Employer may have in law or in
          equity including, without limitation, the right to arbitration
          contained in Section 7(e) hereof and the right to compensatory,
          punitive and monetary damages. In the event that a final
          non-appealable judgment is entered in favor of one of the parties,
          that party shall be reimbursed by the other party for all costs and
          attorneys' fees incurred by such party in such action. Executive
          hereby agrees to waive his right to a jury trial with respect to any
          action commenced to enforce the terms of this Agreement.

          (g)  TRANSITION. Regardless of the reason for his departure from the
          Employer, the Executive agrees that: (i) he shall assist the Employer
          in maintaining the

                                       13
<Page>

          business of the clients and customers with whom the Executive has a
          relationship; and (ii) he shall take all steps reasonably requested by
          the Employer to effect a successful transition of those relationships
          to the person or persons designated by the Employer.

          (h)  SURVIVAL. The provisions of this Section 8 shall survive
          termination of the Executive's employment. The covenants contained in
          Section 8 shall be construed as independent of any of other provisions
          contained in this Agreement and shall be enforceable regardless of
          whether the Executive has a claim against the Employer under the
          Agreement or otherwise.

     9.   COOPERATION. The Executive agrees to give prompt written notice to the
Employer of any claim or injury relating to the Employer, and to fully cooperate
in good faith and to the best of his ability with the Employer in connection
with all pending, potential or future claims, investigations or actions which
directly or indirectly relate to any transaction, event or activity about which
the Executive may have knowledge because of his employment with the Employer.
Such cooperation shall include all assistance that the Employer, its counsel, or
its representatives may reasonably request, including reviewing documents,
meeting with counsel, providing factual information and material, and appearing
or testifying as a witness.

     10.  CONFLICTING AGREEMENTS. Executive hereby represents and warrants that
the execution of this Agreement and the performance of his obligations hereunder
will not breach or be in conflict with any other agreement to which he is a
party or is bound, and that he is not now subject to any covenants against
competition or similar covenants which would affect the performance of his
obligations hereunder.

     11.  NOTICES. All notices or other communications required or permitted to
be given hereunder shall be in writing and shall be delivered by hand and or
sent by prepaid telex, cable or other electronic devices or sent, postage
prepaid, by registered or certified mail or telecopy or overnight courier

                     EMPLOYMENT AND NONCOMPETITION AGREEMENT

     This EMPLOYMENT AND NONCOMPETITION AGREEMENT ("Agreement") is made as of
the ____ day of July, 2001 between Thomas E. Wirth ("Executive") and SL Green
Realty Corp., a Maryland corporation with its principal place of business at 420
Lexington Avenue, New York, New York 10170 (the "Employer").

     1.   TERM. The term of this Agreement shall commence on October 1, 2001
and, unless earlier terminated as provided in Section 6 below, shall terminate
on the third anniversary of the date of this Agreement (the "Original Term");
PROVIDED, HOWEVER, that Section 8 hereof shall survive the termination of this
Agreement as provided therein. The Original Term may be extended for such period
or periods, if any, as may be mutually agreed to in writing by Executive and the
Employer (each a "Renewal Term"). If either party intends not to extend the
Original Term, such party will give the other party at least six (6) months'
written notice of such intention. If either party gives such notice with less
than six (6) months remaining in the Original Term, the term of this Agreement
shall be extended until the date which is six (6) months after the date on which
the notice is given. The period of Executive's employment hereunder consisting
of the Original Term and all Renewal Terms, if any, is herein referred to as the
"Employment Period" and an anniversary of the date of this Agreement is herein
referred to as an "Anniversary."

     2.   EMPLOYMENT AND DUTIES.

          (a)  DUTIES. During the Employment Period, Executive shall be employed
     in the business of the Employer and its affiliates. Executive shall serve
     the Employer as a senior corporate executive and shall have the title of
     Chief Financial Officer of the Employer. Executive will report to the Chief
     Operating Officer and President of the Employer. The Executive shall be
     principally responsible for the financial systems and controls, public
     accounting and reporting and tax planning and implementation for Employer
     and shall provide assistance to Employer's Chief Operating Officer in
     connection with such activities. Executive's duties and authority shall be
     as further set forth in the By-laws of the Employer and as otherwise
     established from time to time by the Chief Operating Officer of the
     Employer, but in all events such duties shall be commensurate with his
     position as Chief Financial Officer of the Employer.

          (b)  BUSINESS TIME AND EFFORTS. Executive agrees to his employment as
     described in this Section 2 and agrees to devote substantially all of his
     business time and efforts to the performance of his duties under this
     Agreement, except as otherwise approved by the Board of Directors of the
     Employer; PROVIDED, HOWEVER, that nothing herein shall be interpreted to
     preclude Executive from (i) participating as an officer or director of, or
     advisor to, any charitable or other tax exempt organization or otherwise
     engaging in charitable, fraternal or trade group activities; and (ii)
     investing his assets as a passive investor in other entities or business
     ventures, provided that he performs no management or similar role with
     respect to such entities or ventures and such investment does not violate
     Section 8 hereof; and/or serving as a member of the Board of Directors

<Page>

     of a for-profit corporation with the approval of the Chief Executive
     Officer of the Company.

          (c)  TRAVEL. In performing his duties hereunder, Executive shall be
     available for all reasonable travel as the needs of the Employer's business
     may require. Executive shall be based in, or within 25 miles of, Manhattan.

     3.   COMPENSATION AND BENEFITS. In consideration of Executive's services
hereunder, the Employer shall compensate Executive as provided in this
Section 3.

          (a)  BASE SALARY. The Employer shall pay Executive an aggregate
     minimum annual salary at the rate of $225,000 per annum during the
     Employment Period ("Base Salary"), subject to applicable tax withholding.
     Base Salary shall be payable bi-weekly in accordance with the Employer's
     normal business practices. Solely for the purpose of determining whether
     Executive's Base Salary payable under this Section 3(a) should be
     increased, the Base Salary shall be subject to review by the Employer's
     Board of Directors or Compensation Committee at least once annually.

          (b)  BONUSES. During the Employment Period, Executive shall receive
     such discretionary annual bonuses as the Employer's Board of Directors, in
     its sole discretion, may deem appropriate to reward Executive for job
     performance; PROVIDED, HOWEVER, that Executive's annual performance bonus
     shall not be less than $100,000. Any bonus shall be subject to applicable
     tax withholdings.

          (c)  STOCK OPTIONS. During the Employment Period, in the sole
     discretion of the Employer's Board of Directors or a committee thereof,
     Executive shall be eligible to participate in the Employer's then current
     Stock Option and Incentive Plan (the "Plan"), which authorizes the grant of
     stock options, stock awards and the making of loans to acquire the
     Employer's common stock ("Common Stock")

          (d)  EQUITY AWARDS. Effective as of the date that this Agreement is
     executed by the Employer and Executive, Executive shall be granted 15,000
     restricted shares of Common Stock. The grant shall become vested and
     nonforfeitable as to 15% of such shares on the first Anniversary, 15% of
     such shares on the second Anniversary and 70% of such shares on the third
     Anniversary in each case subject to (i) the Employer achieving either a 10%
     increase in funds from operations (on a per share basis) or a 15% total
     return (including all dividends and stock appreciation) to shareholders
     during the last fiscal year completed before the applicable vesting date,
     and (ii) the Executive remaining employed by the Employer except as
     otherwise provided herein. Furthermore, (i) if the Employer achieves
     either an increase in funds from operations (on a per share basis) of at
     least 8% (but less than 9%) or a total return to shareholders of at least
     13% (but less than 14%) during the last fiscal year completed before an
     applicable vesting date, then 80% of the restricted shares that otherwise
     would have become vested on such vesting date shall become vested, (ii) if
     the Employer achieves either an increase in funds from operations

                                        2
<Page>

     (on a per share basis) of at least 9% (but less than 10%) or a total
     return to shareholders of at least 14% (but less than 15%) during the last
     fiscal year completed before the applicable vesting date, then 90% of the
     restricted shares that otherwise would have become vested on such vesting
     date shall become vested, and (iii) if the Employer achieves a total return
     to shareholders in the top one-third of a peer group of companies (to be
     determined for such year by the Compensation Committee of the Employer's
     Board of Directors) during the last fiscal year completed before the
     applicable vesting date, then 100% of the restricted shares that otherwise
     would have become vested on such vesting date shall become vested. If
     necessary to reach a vesting threshold for any period, the Compensation
     Committee of the Employer's Board of Directors shall determine such amounts
     by averaging cumulative increases and returns on a look-back or
     look-forward basis. The Employer shall pay Executive an additional cash
     amount as a tax gross-up upon each vesting date equal to 40% of the value
     of the shares included in Executive's taxable income on such date.
     Executive will receive the full cash dividends attributable to all
     nonforfeited shares of restricted stock, regardless of whether such shares
     have become vested on the record date for such dividends.

          (e)  EXPENSES. Executive shall be reimbursed for all reasonable
     business related expenses incurred by Executive at the request of or on
     behalf of the Employer, provided that such expenses are incurred and
     accounted for in accordance with the policies and procedures established by
     the Employer.

          (f)  MEDICAL INSURANCE. During the Employment Period, Executive and
     Executive's immediate family shall be entitled to participate in such
     medical benefit plan as the Employer shall maintain from time to time for
     the benefit of senior executive officers of the Employer and their
     families, on the terms and subject to the conditions set forth in such
     plan. Nothing in this section shall limit the Employer's right to change or
     modify or terminate any benefit plan or program as it sees fit from time to
     time in the normal course of business so long as it does so for all senior
     executives of the Employer.

          (g)  VACATIONS. Executive shall be entitled to reasonable paid
     vacations in accordance with the then regular procedures of the Employer
     governing senior executive officers.

          (h)  OTHER BENEFITS. During the Employment Period, the Employer shall
     provide to Executive such other benefits, including disability insurance,
     sick leave and the right to participate in such retirement or pension
     plans, as are made generally available to senior executive officers and
     employees of the Employer from time to time.

     4.   INDEMNIFICATION AND LIABILITY INSURANCE. Executive hereby warrants
that his execution of this Agreement, and performance of duties hereunder, does
not constitute the breach of any other executed contract to which Executive may
be a party, and does not constitute the breach of any restrictive covenant by
which Executive may be bound. The Employer agrees to indemnify Executive to the
extent permitted by applicable law from and against any and all losses, damages,
claims, liabilities and expenses for which such indemnified party has not

                                        3
<Page>

otherwise been reimbursed (including the costs and expenses of legal counsel
retained by the Employer to defend the Executive and judgments, fines and
amounts paid in settlement actually and reasonably incurred by or imposed on
such indemnified party) with respect to any actions commenced against Executive
either with regard to his entering this Agreement with the Employer or in his
capacity as an officer or director, or former officer or director, of the
Employer or any affiliate thereof for which he may serve in such capacity. The
Employer also agrees to secure and maintain officers and directors liability
insurance providing coverage for Executive.

     5.   EMPLOYER'S POLICIES. Executive agrees to observe and comply with the
reasonable rules and regulations of the Employer as adopted by its Board of
Directors from time to time regarding the performance of his duties and to carry
out and perform orders, directions and policies communicated to him from time to
time by the Employer's Board of Directors.

     6.   TERMINATION. The Executive's employment hereunder may be terminated
under the following circumstances:

          (a)  Termination by the Employer.

               (i)    DEATH. The Executive's employment hereunder shall

          reasonable accommodation on a full-time basis for the entire period of
          four consecutive months or any 120 days in a 180-day period, and

          of his duties hereunder on a full-time basis, the Employer may
          terminate Executive's employment hereunder.

               (iii)  CAUSE. The Employer may terminate Executive's employment
          hereunder for Cause. For purposes of the Agreement, "Cause" shall mean

          laws of the United States or any state or political subdivision
          thereof; (ii) Executive engaged in conduct constituting a material

          position and past performance after receiving notice from the Employer
          specifically identifying the manner in which Executive has failed to
          perform (it being understood that, for this purpose, the manner and
          level of Executive's performance shall not be determined based on the
          financial performance of the Employer).

          Employer to comply with the provisions of Section 3; (ii) a material
          breach by the Employer of any other provision of this Agreement which
          has not been cured within 30 days after notice of noncompliance
          (specifying the nature of the noncompliance) has been given by the
          Executive to the Employer; or (iii) a Force Out upon or following a
          Change-in-Control (as such terms are defined in Section 6(c) below).

          employment by the Employer or by the Executive (other than termination

               (i)    A "Change-in-Control" shall be deemed to have occurred if:

                      (A)  any Person, together with all "affiliates" and
               "associates" (as such terms are defined in Rule 12b-2 under the
               Securities Exchange Act of 1934 (the "Exchange Act")) of such
               Person, shall become the "beneficial owner" (as such term is
               defined in Rule 13d-3 under the Exchange Act), directly or
               indirectly, of securities of the Employer representing 40% or
               more of either (A) the combined voting power of the Employer's
               then outstanding securities having the right to vote in an
               election of the Employer's Board of Directors ("Voting
               Securities") or (B) the then outstanding shares of all classes of
               stock of the Employer (in

                                        5
<Page>

               either such case other than as a result of the acquisition of
               securities directly from the Employer); or

                      (B)  individuals who constitute the Employer's Board of
               Directors (the "Incumbent Directors") cease for any reason,
               including, without limitation, as a result of a tender offer,
               proxy contest, merger or similar transaction, to constitute at
               least a majority of the Employer's Board of Directors, provided
               that any person becoming a director of the Employer whose
               election or nomination for election was approved by a vote of at
               least a majority of the Incumbent Directors shall, for purposes
               of this Agreement, be considered an Incumbent Director; or

                      (C)  the stockholders of the Employer shall approve (1)
               any consolidation or merger of the Employer or any subsidiary
               where the stockholders of the Employer, immediately prior to the
               consolidation or merger, would not, immediately after the
               consolidation or merger, beneficially own (as such term is
               defined in Rule 13d-3 under the Exchange Act), directly or
               indirectly, shares representing in the aggregate at least 50% of
               the voting shares of the corporation issuing cash or securities
               in the consolidation or merger (or of its ultimate parent
               corporation, if any), (2) any sale, lease, exchange or other
               transfer (in one transaction or a series of transactions
               contemplated or arranged by any party as a single plan) of all or
               substantially all of the assets of the Employer or (3) any plan
               or proposal for the liquidation or dissolution of the Employer;

               Notwithstanding the foregoing, a "Change-in-Control" shall not be
          deemed to have occurred for purposes of the foregoing clause (A)
          solely as the result of an acquisition of securities by the Employer
          which, by reducing the number of shares of stock or other Voting
          Securities outstanding, increases (x) the proportionate number of
          shares of stock of the Employer beneficially owned by any Person to
          40% or more of the shares of stock then outstanding or (y) the
          proportionate voting power represented by the Voting Securities
          beneficially owned by any Person to 40% or more of the combined voting
          power of all then outstanding Voting Securities; PROVIDED, HOWEVER,
          that if any Person referred to in clause (x) or (y) of this sentence
          shall thereafter become the beneficial owner of any additional stock
          of the Employer or other Voting Securities (other than pursuant to a
          share split, stock dividend, or similar transaction), then a
          "Change-in-Control" shall be deemed to have occurred for purposes of
          the foregoing clause (A). In addition, notwithstanding the foregoing,
          a "Change-in-Control" shall not be deemed to have occurred if Stephen
          L. Green continues to serve as Chairman of the Board of Directors or
          the equivalent of the surviving entity of any event listed in the
          foregoing clause (A), (B) or (C) and no Force Out (as defined below)
          has occurred with respect to the Executive.

<Page>

               (ii)   A "Force Out" shall be deemed to have occurred in the
          event of a Change-in-Control together with or followed by:

                      (A)  a change in duties, responsibilities, status or
               positions with the Employer that does not represent a promotion
               from or maintaining of Executive's duties, responsibilities,
               status or positions as in effect immediately prior to the
               Change-in-Control, or any removal of Executive from or any
               failure to reappoint or reelect Executive to such positions,
               except in connection with the termination of Executive's
               employment for Cause, disability, retirement, or death;

                      (B)  a reduction by the Employer in Executive's Base
               Salary or bonus compensation as in effect immediately prior to
               the Change-in-Control;

                      (C)  the failure by the Employer to continue in effect any
               of the benefit plans including, but not limited to stock option
               and equity awards, in which Executive is participating at the
               time of the Change-in-Control of the Employer (unless Executive
               is permitted to participate in any substitute benefit plan with
               substantially the same terms and to the same extent and with the
               same rights as Executive had with respect to the benefit plan
               that is discontinued) other than as a result of the normal
               expiration of any such benefit plan in accordance with its terms
               as in effect at the time of the Change-in-Control, or the taking
               of any action, or the failure to act, by the Employer which would
               adversely affect Executive's continued participation in any of
               such benefit plans on at least as favorable a basis to Executive
               as was the case on the date of the Change-in-Control or which
               would materially reduce Executive's benefits in the future under
               any of such benefit plans or deprive Executive of any material
               benefits enjoyed by Executive at the time of the
               Change-in-Control; PROVIDED, HOWEVER, that any such action or
               inaction on the part of the Employer, including any modification,
               cancellation or termination of any benefits plan, undertaken in
               order to maintain such plan in compliance with any federal, state
               or local law or regulation governing benefits plans, including,
               but not limited to, the Employment Retirement Income Security Act
               of 1974, shall not constitute a Force Out for the purposes of
               this Agreement;

                      (D)  the Employer's requiring Executive to be based in an
               office located more than 25 miles from Manhattan, except for
               required travel relating to the Employer's business to an extent
               substantially consistent with the business travel obligations
               which Executive undertook on behalf of the Employer prior to the
               Change-in-Control; or

                                        7
<Page>

                      (E)  the failure by the Employer to obtain from any
               successor to the Employer an agreement to be bound by this
               Agreement pursuant to Section 13 hereof.

               (iii)  "Person" shall have the meaning used in Sections 13(d) and
          14(d) of the Exchange Act; provided however, that the term "Person"
          shall not include (A) Stephen L. Green or Nancy A. Peck, or (B) the
          Employer, any of its subsidiaries, or any trustee, fiduciary or other
          person or entity holding securities under any employee benefit plan of
          the Employer or any of its subsidiaries.

     7.   COMPENSATION UPON TERMINATION OR DURING DISABILITY.

          (a)  TERMINATION WITHOUT CAUSE OR WITH GOOD REASON. If (i) Executive
     is terminated without Cause pursuant to Section 6(a)(iv) above, or (ii)
     Executive shall terminate his employment hereunder with Good Reason
     pursuant to Section (6)(b)(ii) above, then the Employment Period shall
     terminate as of the effective date set forth in the written notice of such
     termination (the "Termination Date") and Executive shall be entitled to the
     following benefits:

               (i)    The Employer shall continue to pay Executive's Base Salary
          (at the rate in effect on the date of his termination) and annual
          performance bonus (based on the amount paid for the immediately
          preceding year or, if the termination takes place prior to a bonus
          having been previously so paid, the sum of $100,000) for the remaining
          term of the Employment Period after the date of Executive's
          termination, on the same periodic payment dates as payment would have
          been made to Executive had the Employment Period not been terminated
          for the remaining term of the Employment Period after the date of
          Executive's termination; PROVIDED, HOWEVER, that if such termination
          occurs upon or following a Change-in-Control, the Employer shall
          continue to pay Executive's Base Salary (at the rate in effect on the
          date of his termination) and annual performance bonus (based on the
          highest amount paid for the three preceding years or, if the
          termination takes place prior to a bonus having been previously so
          paid, the sum of $100,000) for the remaining term of the Employment
          Period after the date of Executive's termination. It is expressly
          agreed that the Executive shall receive a bonus for each remaining
          year of this Agreement and that the bonus will be paid in a lump sum
          within thirty (30) days after the Executive's termination.

               (ii)   For the remaining term of the Employment Period, Executive
          shall continue to receive all benefits described in Section 3 existing
          on the date of termination, including, but not limited to, any bonuses
          or equity awards described in Section 3 of this Agreement, subject to
          the terms and conditions upon which such benefits may be offered. For
          purposes of the application of such benefits, Executive shall be
          treated as if he had remained in the employ of the Employer with a
          Base Salary at the rate in effect on the date of termination.

                                        8
<Page>

               (iii)  Any unvested shares of restricted stock granted to the
          Executive by the Employer shall become vested on the date of the
          Executive's termination.

               (iv)   If Executive obtains other employment, or receives any
          wages for services rendered to any person or entity during the
          remaining term of Employment Period after the date of Executive's
          termination, the payments due under Section 7(a)(i) will be reduced by
          the amount of such wages. Executive shall give prompt notice to the
          Employer of any such employment undertaken or services rendered by
          him, which notice shall include a description of the wages he will
          receive, the date of receipt, and a copy of each relevant agreement or
          contract. Executive shall also give prompt notice to the Employer of
          any changes in such employment or wages.

               (v)    If in the opinion of tax counsel selected by the Executive
          and reasonably acceptable to the Employer, the Executive has or will
          receive any compensation (including without limitation as a result of
          the accelerated vesting of equity awards) or recognize any income
          (whether or not pursuant to this Agreement or any plan or other
          arrangement of the Employer and whether or not the Employment Period
          or the Executive's employment with the Employer has terminated) which
          will constitute an "excess parachute payment" within the meaning of
          Section 280G(b)(1) of the Internal Revenue Code (the "Code") (or for
          which a tax is otherwise payable under Section 4999 of the Code or any
          successor provision thereto), then the Employer shall pay the
          Executive an additional amount (the "Additional Amount") equal to the
          sum of (i) all taxes payable by the Executive under Section 4999 of
          the Code with respect to all such excess parachute payments and any
          such Additional Amount, plus (ii) all federal, state and local income
          taxes payable by Executive with respect to any such Additional Amount.
          Any amounts payable pursuant to this paragraph (v) shall be paid by
          the Employer to the Executive within 30 days of each written request
          therefor made by the Executive.

          (b)  TERMINATION FOR CAUSE OR WITHOUT GOOD REASON. If (i) Executive is
     terminated for Cause pursuant to Section 6(a)(iii)(i-iii) above, or (ii)
     Executive shall voluntarily terminate his employment hereunder without Good
     Reason pursuant to Section 6(b)(ii) above, then the Employment Period shall
     terminate as of the effective date set forth in the written notice of such
     termination (the "Termination Date") and Executive shall be entitled to
     receive only his Base Salary at the rate then in effect until the
     Termination Date and any outstanding stock options held by Executive shall
     expire in accordance with the terms of the stock option plan or option
     agreement under which the stock options were granted.

          (c)  TERMINATION BY REASON OF DEATH. If Executive's employment
     terminates due to his death, the Employer shall pay Executive's Base Salary
     plus any applicable pro rata portion of the annual performance bonus
     described in Section 3(c) above for a period

                                        9
<Page>

     of six months from the date of his death, or such longer period as the
     Employer's Board of Directors may determine, to Executive's estate or to a
     beneficiary designated by Executive in writing prior to his death. If such
     death occurs during a vesting period, a pro rata portion of the unvested
     shares of restricted stock granted to the Executive that otherwise would
     have become vested upon the conclusion of such vesting period shall become
     vested on the date of the Executive's termination due to his death, and a
     pro rata portion of the unexercisable stock options granted to the
     Executive that otherwise would have become exercisable upon the conclusion
     of such vesting period shall become exercisable on the date of the
     Executive's termination due to such death. Furthermore, upon such death,
     any unexercised stock options granted to the Executive shall remain
     exercisable until the earlier of (A) the date on which the term of such
     stock options otherwise would have expired, or (B) the second January 1
     after the date of the Executive's termination due to his death.

          (d)  TERMINATION BY REASON OF DISABILITY. In the event that
     Executive's employment terminates due to his disability as defined in
     Section 6(a)(ii) above, Executive shall be entitled to be paid his Base
     Salary plus any applicable pro rata portion of the annual performance bonus
     described in Section 3(c) above for a period of six months from the date of
     such termination, or for such longer period as such benefits are then
     provided with respect to other senior executives of the Employer. If such
     disability occurs during a vesting period, a pro rata portion of the
     unvested shares of restricted stock granted to the Executive that otherwise
     would have become vested upon the conclusion of such vesting period shall
     become vested on the date of the Executive's termination due to his
     disability, and a pro rata portion of the unexercisable stock options
     granted to the Executive that otherwise would have become exercisable upon
     the conclusion of such vesting period shall become exercisable on the date
     of the Executive's termination due to such disability. Furthermore, upon
     such disability, any unexercised stock options granted to the Executive
     shall remain exercisable until the earlier of (A) the date on which the
     term of such stock options otherwise would have expired, or (B) the second
     January 1 after the date of the Executive's termination due to his
     disability.

          (e)  ARBITRATION IN THE EVENT OF A DISPUTE REGARDING THE NATURE OF
     TERMINATION. In the event that the Executive's employment is terminated by
     the Employer for Cause or by Executive for Good Reason, and Executive
     contends that such Cause or Good Reason did not exist, the parties agree to
     submit such claim to arbitration before the American Arbitration
     Association ("AAA"), and Executive and Employer hereby agrees to submit to
     any such dispute to arbitration pursuant to the terms of this Section 7(e).
     In such a proceeding, the only issue before the arbitrator will be whether
     Executive's employment was in fact terminated for Cause or for Good Reason,
     as the case may be. If the arbitrator determines that Executive's
     employment was terminated by the Employer without Cause or was terminated
     by Executive for Good Reason, the only remedy that the arbitrator may award
     is an amount equal to the severance payments specified in Section 7, the
     costs of arbitration, and Executive's attorneys' fees. If the arbitrator
     finds that Executive's employment was terminated by the Employer for Cause

                                       10
<Page>

     or by the Executive without Good Reason, the arbitrator will be without
     authority to award Executive anything, and the parties will each be
     responsible for their own attorneys' fees, and the costs of arbitration
     will be paid 50% by Executive and 50% by the Employer.

     8.   CONFIDENTIALITY; PROHIBITED ACTIVITIES. The Executive and the Employer
recognize that due to the nature of his employment and relationship with the
Employer, the Executive has access to and develops confidential business
information, proprietary information, and trade secrets relating to the business
and operations of the Employer. The Executive acknowledges that such information
is valuable to the business of the Employer, and that disclosure to, or use for
the benefit of, any person or entity other than the Employer, would cause
irreparable damage to the Employer. The Executive further acknowledges that his
duties for the Employer include the duty to develop and maintain client,
customer, employee, and other business relationships on behalf of the Employer;
and that access to and development of those close business relationships for the
Employer render his services special, unique and extraordinary. In recognition
that the good will and business relationships described herein are valuable to
the Employer, and that loss of or damage to those relationships would destroy or
diminish the value of the Employer, the Executive agrees as follows:

          (a)  CONFIDENTIALITY. During the term of this Agreement (including any
     renewals), and at all times thereafter, the Executive shall maintain the
     confidentiality of all confidential or proprietary information of the
     Employer ("Confidential Information"), and, except in furtherance of the
     business of the Employer or as specifically required by law or by court
     order, he shall not directly or indirectly disclose any such information to
     any person or entity; nor shall he use Confidential Information for any
     purpose except for the benefit of the Employer. For purposes of the
     Agreement, "Confidential Information" includes, without limitation: client
     or customer lists, identities, contacts, business and financial information
     (excluding those of Executive prior to employment with Employer);
     investment strategies; pricing information or policies, fees or commission
     arrangements of the Employer; marketing plans, projections, presentations
     or strategies of the Employer; financial and budget information of the
     Employer; new personnel acquisition plans; and all other business related
     information which has not been publicly disclosed by the Employer. This
     restriction shall apply regardless of whether such Confidential Information
     is in written, graphic, recorded, photographic, data or any machine
     readable form or is orally conveyed to, or memorized by, the Executive.

          (b)  PROHIBITED ACTIVITIES. Because Executive's services to the
     Employer are essential and because Executive has access to the Employer's
     Confidential Information, Executive covenants and agrees that:

               (i)    (A) during the Employment Period, and (B) in the event
          that this Agreement is terminated (I) by the Employer for Cause or
          (II) by the Executive for any reason other than death, disability,
          Good Reason or the expiration of the term of the Agreement, Executive
          will not, without the prior written consent of

                                       11
<Page>

          the Board of Directors of the Employer which shall include the
          unanimous consent of the Directors who are not officers of the
          Employer, directly or indirectly (individually, or through or on
          behalf of another entity as owner, partner, agent, employee,
          consultant, or in any other capacity), during the Noncompetition
          Period, solicit or accept any offer or grant of employment in the
          greater New York metropolitan area, whether as an owner, partner,
          employee, consultant, director, officer, trustee or agent, (it being
          understood that the restrictions regarding such activities shall not
          apply with respect to any termination of this Agreement by the
          Executive upon or after the occurrence of a Change-in-Control); and

               (ii)   during the Employment Period, and during the two-year
          period following the termination of the Executive by either party for
          any reason (including the expiration of the term of the Agreement),
          Executive will not, without the prior written consent of the Board of
          Directors of the Employer which shall include the unanimous consent of
          the Directors who are not officers of the Employer, directly or
          indirectly (individually, or through or on behalf of another entity as
          owner, partner, agent, employee, consultant, or in any other
          capacity), solicit, encourage, or engage in any activity to induce any
          Employee of the Employer to terminate employment with the Employer, or
          to become employed by, or to enter into a business relationship with,
          any other person or entity. For purposes of this subsection, the term
          Employee means any individual who is an employee of or consultant to
          the Employer (or any affiliate) during the six-month period prior to
          Executive's last day of employment.

          (c)  NONCOMPETITION PERIOD. For purposes of this Section 8, the
     Noncompetition Period shall mean the period commencing on the date of
     termination of Executive's employment under this Agreement and ending on
     the earlier of (i) the date on which the term of this Agreement otherwise
     would have expired, or (ii) the first anniversary of the date of
     termination of Executive's employment under this Agreement.

          (d)  PASSIVE INVESTMENTS. During the term of Employment Period,
     notwithstanding anything contained herein to the contrary, Executive is not
     prohibited by this Section 8 from making investments in any entity that
     engages, directly or indirectly, in the acquisition, development,
     construction, operation, management, financing or leasing of office real
     estate properties, regardless of where they are located if Executive's
     aggregate investment in such entity constitutes less than one percent (1%)
     of the equity ownership of such entity.

          (e)  EMPLOYER PROPERTY. The Executive acknowledges that all originals
     and copies of materials, records and documents generated by him or coming
     into his possession during his employment by the Employer are the sole
     property of the Employer ("Employer Property"). During his employment, and
     at all times thereafter, the Executive shall not remove, or cause to be
     removed, from the premises of the Employer,

                                       12
<Page>

     copies of any record, file, memorandum, document, computer related
     information or equipment, or any other item relating to the business of the
     Employer, except in furtherance of his duties under the Agreement. When the
     Executive terminates his employment with the Employer, or upon request of
     the Employer at any time, the Executive shall promptly deliver to the
     Employer all originals and copies of Employer Property in his possession or
     control and shall not retain any originals or copies in any form.

          (f)  NO DISPARAGEMENT. For one year following termination of the
     Executive's employment for any reason, the Executive shall not
     intentionally disclose or cause to be disclosed any negative, adverse or
     derogatory comments or information about (i) the Employer and its parent,
     affiliates or subsidiaries, if any; (ii) any product or service provided by
     the Employer and its parent, affiliates or subsidiaries, if any; or (iii)
     the Employer's and its parent's, affiliates' or subsidiaries' prospects for
     the future. For one year following termination of the Executive's
     employment for any reason, the Employer shall not disclose or cause to be
     disclosed any negative, adverse or derogatory comments or information about
     the Executive. Nothing in this Section shall prohibit either the Employer
     or the Executive from testifying truthfully in a judicial or administrative
     proceeding in response to a subpoena.

          (g)  REMEDIES. The Executive declares that the foregoing limitations
     in Sections 8(a) through 8(f) above are reasonable and necessary for the
     adequate protection of the business and the goodwill of the Employer. In
     any restriction contained in this Section 8 shall be deemed to be invalid,
     illegal or unenforceable by reason of the extent, duration or scope
     thereof, or otherwise, then the court making such determination shall have
     the right to reduce such extent, duration, scope, or other provisions
     hereof to make the restriction consistent with applicable law, and in its
     reduced form such restriction shall then be enforceable in the manner
     contemplated hereby. In the event that the Executive breaches any of the
     promises contained in this Section 8, the Executive acknowledges that the
     Employer's remedy at law for damages will be inadequate and that the
     Employer will be entitled to specific performance, a temporary restraining
     order or preliminary injunction to prevent the Executive's prospective or
     continuing breach and to maintain the status quo. The existence of this
     right to injunctive relief, or other equitable relief, or the Employer's
     exercise of any of these rights, shall not limit any other rights or
     remedies the Employer may have in law or in equity, including, without
     limitation, the right to arbitration contained in Section 7(c) hereof and
     the right to compensatory and monetary damages. In the event that a final
     non-appealable judgment is entered in favor of one of the parties, that
     party shall be reimbursed by the other party for all costs and attorneys'
     fees incurred by such party in such action. Executive hereby agrees to
     waive his right to a jury trial with respect to any action commenced to
     enforce the terms of this Agreement.

          (h)  TRANSITION. Regardless of the reason for his departure from the
     Employer, the Executive agrees that at Employer's sole costs and expense,
     for a period of not more

                                       13
<Page>

     than thirty (30) days after termination of Executive, he shall take all
     steps reasonably requested by the Employer to effect a successful
     transition of client and customer relationships to the person or persons
     designated by the Employer, and a transition of the systems, controls,
     reporting processes, programs and other operational components within
     Executive's position.

          (i)  COOPERATION WITH RESPECT TO LITIGATION. During the Employment
     period and at all times thereafter, Executive agrees to give prompt written
     notice to the Employer of any claim relating to the Employer and to
     cooperate fully, in good faith and to the best of his ability with the
     Employer in connection with any and all pending, potential or future
     claims, investigations or actions which directly or indirectly relate to
     any action, event or activity about which Executive may have knowledge in
     connection with or as a result of his employment by the Employer
     hereinunder. Such cooperation will include all assistance that the
     Employer, its counsel or its representatives may reasonably request,
     including reviewing documents, meeting with counsel, providing factual
     information and material, and appearing or testifying as a witness;
     provided, however, that the Employer will reimburse Executive for all
     reasonable expenses, including travel, lodging and meals, incurred by him
     in fulfilling his obligations under this Section 8(i) and, except as may be
     required by law or by court order, should Executive then be employed by an
     entity other than the Employer, such cooperation will not materially
     interfere with Executive's then current employment.

          (j)  SURVIVAL. The provisions of this Section 8(a) shall survive
     termination of the Executive's employment and those of Section 8(b) shall
     survive for the periods specified therein following termination. The
     covenants contained in Section 8 shall be construed as independent of any
     of other provisions contained in this Agreement and shall be enforceable
     regardless of whether the Executive has a claim against the Employer under
     the Agreement or otherwise.

     9.   CONFLICTING AGREEMENTS. Executive hereby represents and warrants that
the execution of this Agreement and the performance of his obligations hereunder
will not breach or be in conflict with any other agreement to which he is a
party or is bound, and that he is not now subject to any covenants against
competition or similar covenants which would affect the performance of his
obligations hereunder.

     10.  NOTICES. All notices or other communications required or permitted to
be given hereunder shall be in writing and shall be delivered by hand and or
sent by prepaid telex, cable or other electronic devices or sent, postage
prepaid, by registered or certified mail or telecopy or overnight courier
service and shall be deemed given when so delivered by hand, telexed, cabled or
telecopied, or if mailed, three days after mailing (one business day in the case
of express mail or overnight courier service), as follows:

          (a)  if to the Executive:
