Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrants under any of the following provisions (see General Instruction A.2. below): |_| Written communications pursuant to Rule 425 under the Securities Act (17 CFR 230.425) |_| Soliciting material pursuant to Rule 14a-12 under the Exchange Act (17 CFR 240.14a-12) |_| Pre-commencement communications pursuant to Rule 14d-2(b) under the Exchange Act (17 CFR 240.14d-2(b)) |_| Pre-commencement communications pursuant to Rule 13e-4(c) under the Exchange Act (17 CFR 240.13e-4(c)) Item 1.01. Entry into a Material Definitive Agreement. On December 27, 2004, Reckson Operating Partnership, L.P. (the "Operating Partnership") entered into definitive agreements with certain senior officers of Reckson Associates Realty Corp. (the "Company") to revise the 2003 incentive awards under their Amended and Restated Long-Term Incentive Award Agreements pursuant to the Reckson Associates Realty Corp. 2003 Long-Term Incentive Plan (the "2003 LTIP"). The revised agreements provide for (i) the rescission of the unvested portion of their core awards of shares of restricted stock of the Company (the "Core Awards") and (ii) the award in exchange for the rescinded Core Awards of an equal number of units of a new class of limited partnership interests ("LTIP Units") of the Operating Partnership. The 2003 LTIP consists of (i) the Core Award, which provides for annual stock-based compensation based on attaining certain annual performance measures and in part upon continued service with the Company, and (ii) an outperformance award, which provides for compensation to be earned at the end of a four-year period if the Company attains certain cumulative performance measures. The revised 2003 LTIP was designed to provide the potential for executives to retain a greater equity interest in the Company by eliminating the need for executives to sell a portion of their Core Awards immediately upon vesting in order to satisfy personal income taxes which are due upon vesting under the original Core Awards. The terms of each award of LTIP Units are substantially similar to those of the Core Awards. The vesting, performance hurdles and timing for vesting remain unchanged. However, an LTIP Unit represents an equity interest in the Operating Partnership, rather than the Company. At issuance, the LTIP Unit has no value but may over time accrete to a value equal to (but never greater than) the value of one share of common stock of the Company (a "REIT Share"). Initially, LTIP Units will not have full parity with common units of the Operating Partnership with respect to liquidating distributions. Upon the occurrence of certain "triggering events," the Operating Partnership will revalue its assets for the purpose of the capital accounts of its partners and any increase in valuation of the Operating Partnership's assets from the date of the issuance of the LTIP Units through the "triggering event" will be allocated to the capital accounts of holders of LTIP Units until their capital accounts are equivalent to the capital accounts of holders of common units. If such equivalence is reached, LTIP Units would achieve full parity with common units for all purposes, and therefore accrete to an economic value equivalent to REIT Shares on a one-for-one basis. If such parity is reached, vested LTIP Units may be redeemed for cash in an amount equal to the then fair market value of an equal number of REIT Shares or converted into an equal number of common units of the Operating Partnership, as determined by the Company's Compensation Committee. However, there are circumstances under which such economic equivalence would not be reached. Until and unless such economic equivalence is reached, the value that the senior officers will realize for vested LTIP Units will be less than the value of an equal number of REIT Shares. In addition, unlike Core Awards (wherein dividends that accumulate during the 2003 LTIP are paid upon vesting), LTIP Units will receive the same quarterly distributions as common units of the Operating Partnership on a current basis, thus providing full dividend equivalence with REIT Shares. When the executives first vest under their respective Long-Term Incentive OP Unit Award Agreements in accordance with the specified performance hurdles, they will receive a one-time cash payment that will represent payment of the full amount of the accrued unpaid dividends under the Core Award through the issuance date of the LTIP Units. In order to more closely replicate the terms of the Core Awards being rescinded, on December 27, 2004, the Company also entered into agreements with Messrs. Rechler, Maturo and Barnett, which provide that in the event of a change of control the executive shall receive the equivalent value of one REIT Share for each LTIP Unit. Each senior officer participating in the 2003 LTIP was offered the option to retain all or a portion of his or her Core Awards or to rescind them in exchange for new awards of LTIP Units. Effective December 27, 2004, each of the senior officers named below accepted such offer and thereby amended his or her Amended and Restated Long-Term Incentive Award Agreement to cancel his or her unvested Core Award, and received an equal number of LTIP Units, as specified in each respective Long-Term Incentive OP Unit Award Agreement.

The partnership units were issued in reliance on the exemption provided by Rule 506 promulgated by the U.S. Securities and Exchange Commission under the Securities Act of 1933, as amended.

      F.    The Grantee and the Company wish to amend the Amended and Restated

Agreement as follows:

            Shares would have become Vested Core Shares pursuant to Section
            3(b) of the Award Agreement, the Grantee shall receive a one-time
            cash payment which shall represent the full amount of all such
            accrued dividends under the Award Agreement. After the date
            hereof, no further dividends will accrue with respect to the
            Unvested Core Shares.

                  D.    All Other Terms. The Award Agreement shall remain in
            full force and effect except as expressly modified or amended by

                                   --------

       A. The Grantee is an executive officer of Reckson Associates Realty
 Corp. (the "Company") or one of its Affiliates.

       B. Effective as of March 13, 2003, the Company's Board of Directors
 adopted a long-term incentive plan ("LTIP") designed to provide the Company's
 Executive Officers and certain other key senior employees with their
 incentive compensation through March 2007.

       C. The Grantee was selected by the Compensation Committee of the Board
 of Directors of the Company (the "Committee") to receive an award under the
 LTIP and effective as of March 13, 2003, received a grant of _____ shares, of
 common stock ($0.01 par value per share) of the Company (the "Common Stock")
 as a core annual long-term incentive award (the "Core Award").

       D. Of the Core Award, __________ restricted shares of Common Stock have
 vested (the "Vested Core Award") and _________ restricted shares of Common
 Stock remain unvested (the "Unvested Core Award".)

       E. The Company's Board of Directors has caused the Company's subsidiary
 Reckson Operating Partnership, L.P., a Delaware limited partnership (the
 "Partnership"), to adopt a long-term incentive plan (the "OP LTIP") pursuant
 to which the Grantee is eligible to rescind his or her Unvested Core Award in
 exchange for a new grant (the "Substitute OP Award") under the OP LTIP
 pursuant to the Agreement of Limited Partnership of the Partnership, dated as
 of June 2, 1995, as amended through the date hereof (the "Partnership
 Agreement"), in the form of a Partnership Interest (as defined in the
 Partnership Agreement) having the rights, voting powers, restrictions,
 limitations as to distributions, qualifications and terms and conditions of
 redemption set forth herein and in the Amendment to the Partnership Agreement
 attached hereto as Annex A (the "ALP Amendment"), such Partnership Interest
 to be expressed as a number of Partnership Units (as defined in the
 Partnership Agreement) which shall be referred to as Long-Term Incentive
 Units ("LTIP OP Units"). Upon acceptance of this Long-Term Incentive Plan OP
 Unit Award Agreement (the "Agreement"), the Grantee shall receive the number
 of LTIP OP Units specified above, subject to the restrictions and conditions
 set forth herein and in the Partnership Agreement.






            NOW, THEREFORE, the Company hereby grants to the Grantee,
effective as of the Date of Grant specified above, the number of LTIP OP Units
listed above subject to the terms and conditions of this Agreement.

      1.    Acceptance:

            (a)   The Grantee shall have no rights with respect to this
Agreement and this Agreement shall be revocable by the Grantee until he or she
shall have accepted this Agreement prior to the close of business on the Final
Acceptance Date specified above by (i) signing and delivering to the
Partnership a copy of this Agreement, (ii) signing and delivering an amendment
to the Grantee's Amended and Restated Long-Term Incentive Award Agreement with
respect to the recission of his or her Unvested Core Award (attached hereto as
Annex B), and (iii) unless the Grantee is already a Limited Partner (as
defined in the Partnership Agreement), signing, as a Limited Partner, and
delivering to the Partnership a counterpart signature page to the Partnership
Agreement (attached hereto as Annex C). Upon acceptance of this Agreement by
the Grantee, the Partnership Agreement shall be amended to reflect the
issuance to the Grantee of the LTIP OP Units so accepted and the Partnership
shall deliver to the Grantee a certificate of the Company certifying the
number of LTIP OP Units then issued to the Grantee. Thereupon, the Grantee
shall have all the rights of a Limited Partner of the Partnership with respect
to the number of LTIP OP Units specified above, as set forth in the
Partnership Agreement, subject, however, to the restrictions and conditions
specified in Section 2 below.

            (b)   The LTIP OP Units will not be granted under the Company's
2002 Stock Option Plan (the "Plan") and the OP has been established as an
incentive program of the Partnership. Accordingly, the Grantee must be
eligible to receive the Substitute OP Award in compliance with applicable
Federal and state securities laws and to that effect is required to complete,
execute and deliver certain Covenants, Representations and Warranties
(attached as Annex D). However, the Committee may, in its sole and absolute
discretion, seek to have the OP LTIP become part of the Plan at a future time,
whereby the Substitute OP Award would become an award under the Plan, the LTIP
OP Units will be made convertible into Class A common operating partnership
units of the Partnership ("OPU") and the terms and conditions set forth in the
ALP Amendment under the heading "Right to Convert LTIP Units into Common
Units" will become operative. The Grantee acknowledges that if Committee
elects, in its sole discretion, to cause the LTIP OP Units to become
convertible into OPU, the terms of the LTIP OP Units will change as provided
in the ALP Amendment and the Grantee will have no right to approve or
disapprove such change. In this regard, the Company agrees that (i) the shares
of the Company's Common Stock previously granted to the Grantee pursuant to
the Unvested Core Award shall be reserved under the Plan in connection with
the possible activation of the OP Conversion Feature of the LTIP OP Units, and
(ii) such shares shall not be available for other awards under the Plan.

      2.    Restrictions and Conditions:

            (a)   The records of the Partnership evidencing the LTIP OP Units
granted herein shall bear an appropriate legend, as determined by the
Partnership in its sole discretion, to


                                       2



the effect that such LTIP OP Units are subject to restrictions as set forth
herein, in the ALP Amendment and in the Partnership Agreement.

            (b)   None of the LTIP OP Units awarded to the Grantee hereunder
shall be sold, assigned, transferred, pledged, hypothecated, given away or in
any other manner disposed of, encumbered, whether voluntarily or by operation
of law, or redeemed in accordance with the Partnership Agreement or the ALP
Amendment (a) prior to vesting, (b) for a period of two (2) years beginning on
Date of Grant specified above other than in connection with a
Change-in-Control, or (c) unless such transfer is in compliance with all
applicable securities laws (including, without limitation, the Securities
Act), and such disposition is in accordance with the applicable terms and
conditions of the Partnership Agreement and the ALP Amendment. In connection
with any transfer of LTIP OP Units, the Company may require the transferor to
provide at the Grantee's own expense an opinion of counsel to the transferor,
satisfactory to the Company, that such transfer is in compliance with all
foreign, federal and state securities laws (including, without limitation, the
Securities Act). Any attempted disposition of LTIP OP Units not in accordance
with the terms and conditions of this Section 2(b) shall be null and void, and
the Partnership shall not reflect on its records any change in record
ownership of any LTIP OP Units as a result of any such disposition, shall
otherwise refuse to recognize any such disposition and shall not in any way
give effect to any such disposition of any LTIP OP Units.

            (c)   Except as otherwise provided in Section 3 hereof or
elsewhere herein, if the Grantee's employment with the Company or its
Affiliates is voluntarily or involuntarily terminated for any reason prior to
vesting of the LTIP Units granted herein, the Grantee shall forfeit all LTIP
Units that are not vested as of the date of such termination of employment.

      3.    Vesting of the LTIP OP Units: The LTIP OP Units generally will
become vested as follows:

            (a)   8.333% of the LTIP OP Units will become cumulatively vested
on each of the first three anniversaries of the Date of Grant (each such
anniversary hereinafter referred to as an "Annual Vesting Date"); in each case
provided that the Grantee remains in continuous employment with the Company or
any of its Affiliates until such date.

            (b)   25.0% of the LTIP OP Units will become cumulatively vested
on each of the Annual Vesting Dates; in each case provided that the Grantee
remains in continuous employment with the Company or any of its Affiliates
until such date; and provided, further, that any LTIP OP Units which otherwise
would become vested on such Annual Vesting Date will not become so vested
unless the Company has achieved, with regard to each Annual Vesting Date,
during the last calendar year completed immediately preceding the applicable
Annual Vesting Date, a total return to shareholders (including all Common
Stock dividends and stock appreciation) based on the respective Annual Core
Base Price that either (i) is at or above the 50th percentile of the total
return to shareholders achieved by members of the Peer Group during the same
period, or (ii) subject to the provisions of Section 3(f), equals a total
return of at least 9% per annum. If the vesting performance requirement is not
satisfied for a given annual period other than the calendar year immediately
preceding the third Annual Vesting Date, the LTIP OP


                                       3



Units from such year or years will not be forfeited and will become vested on
any subsequent Annual Vesting Date on which the vesting performance
requirement applicable to such LTIP OP Units is satisfied on a cumulative and
compounded basis as measured for an extended performance period beginning with
the annual period for which the vesting performance requirement was not
satisfied through the calendar year ended immediately preceding the relevant
Annual Vesting Date. If necessary, this cumulative and compounded method of
satisfying the vesting performance requirement will continue to be applied on
a look-back basis on each calendar year end until the end of the three-year
vesting performance period (i.e., through the end of the calendar year
immediately preceding the third Annual Vesting Date) at which time any LTIP OP
Units subject to vesting under this Section 3(b) that have not become vested
shall become vested if at such date the vesting performance requirement is
satisfied on a cumulative and compounded basis for an extended performance
period commencing on March 13, 2003 and measured through the calendar year
ended immediately preceding the third Annual Vesting Date based upon the
Initial Core Base Price. For purposes of this Section, (i) the performance of
the Company relative to the performance of members of the Peer Group will be
determined using the VWAP for the last ten trading days of the Company's
Common Stock and the common stock of the members of the Peer Group at the
applicable calendar year end, and (ii) the per annum percentage performance of
the Company will be determined using the VWAP for the last ten trading days
for the period ending at the applicable calendar year end.

            (c)   Notwithstanding the foregoing, if a Change-in-Control occurs
prior to the third Annual Vesting Date and the Grantee remains in continuous
employment with the Company or any of its Affiliates until such occurrence,
all non-vested LTIP OP Units will thereupon become fully vested provided that,
if (i) a Change-in-Control shall occur and (a) the Company continues in
existence as a public company or (b) another company is the successor to the
Company in a transaction whereby holders of Common Stock receive common stock
of the successor company (or a combination of common stock and cash) and such
successor company expressly assumes the obligations of the Company as the
general partner of the Partnership, and (ii) a Change-in-Control occurs and
(a) the Partnership continues in existence as the operating partnership of the
Company (in the event described in clause (i)(a) above) or (b) another limited
partnership, limited liability company or similar entity is the successor to
the Partnership in a transaction whereby holders of OPU and LTIP OP Units
receive equity interests in such successor entity having substantially
identical rights, voting powers, restrictions, limitations as to
distributions, qualifications and terms and conditions of redemption as the
OPU and LTIP OP Units, respectively, and expressly assumes the obligations
under this Agreement, and (iii) the Grantee continues employment with the
Company or such successor company or their Affiliates, as the case may be, and
a Force Out does not occur, then no vesting shall occur under this Section
3(c) as a result of such Change-in-Control, but this Agreement and the awards
hereunder shall continue in effect on the terms hereof, subject to the
adjustment of the Annual Core Base Price as may be appropriate pursuant to
Section 7 hereof. Notwithstanding the foregoing, if a Change-in-Control
occurs, subsequent to the calendar year end immediately preceding the third
Annual Vesting Date and prior to the third Annual Vesting Date, it shall have
no effect upon the vesting (or not) of the LTIP OP Units (i.e., if the vesting
performance requirements of Section 3(b) were satisfied at the calendar year
end immediately preceding the third Annual Vesting Date


                                       4



any unvested LTIP OP Units shall vest upon such Change-in-Control and, if such
vesting performance requirements were not satisfied then any remaining LTIP OP
Units shall not vest.)

            (d)   Notwithstanding the foregoing, if the Grantee's employment
with the Company and all Affiliates is terminated prior to the third Annual
Vesting Date by reason of the Grantee's death or Disability, by the Grantee
for Good Reason, or by the Company or any Affiliate for any reason other than
Cause or transfer to another Affiliate, all non-vested LTIP OP Units will
thereupon become fully vested. If the Grantee's employment with the Company
and all Affiliates is terminated prior to the third Annual Vesting Date for
any other reason, any LTIP OP Units that have not yet become vested will
thereupon be forfeited.

            (e)   Notwithstanding the foregoing, if the Grantee remains in
continuous employment with the Company or any of its Affiliates until an
applicable Annual Vesting Date but the vesting performance requirement is not
satisfied for the calendar year end immediately preceding such date (or any
extended performance period as contemplated in Section 3(b) above), and if the
Committee determines that it nevertheless would be consistent with the spirit
and intent of this Agreement to vest some or all of the LTIP OP Units that
otherwise would have become vested on that Annual Vesting Date, then the
Committee, in its sole and absolute discretion, may elect to vest some or all
of such LTIP OP Units.

            (f)   Notwithstanding the foregoing, in the event that (i) the
LTIP OP Units would become vested as a result of the Company achieving a total
return of at least 9% per annum in accordance with the terms of Section 3(b),
(ii) the appreciation in the share price of the Common Stock alone has not
resulted in the Company achieving such a 9% per annum total return (i.e.,
without taking into account any dividends paid to holders of Common Stock),
and (iii) the Company's Dividend Payout Ratio with regard to its Cash
Available for Distribution exceeds 100% for any relevant annual period or
periods, the Committee may, in its sole discretion, review whether it is
appropriate for the LTIP OP Units to vest for such period or periods, and may
determine that the LTIP OP Units shall not vest, in whole or in part, based
upon such facts as it deems appropriate including, but not limited to, the
effect on the Dividend Payout Ratio of rent concessions, tenant improvements,
capital expenditures by the Company and similar matters that represent uses of
operating cash flow for the purpose of generating incremental cash flow or
other returns for the Company.

      4.    Distributions. Distributions on the LTIP OP Units shall be paid
currently to the Grantee in accordance with the terms of the Partnership
Agreement.

      5.    Adjustment. The Committee will make or provide for such
adjustments in the number of LTIP OP Units and the vesting performance
requirements applicable to LTIP OP Units, as the Committee may in good faith
determine to be equitably required in order to prevent any dilution or
expansion of the rights of the Grantee that otherwise would result from (i)
any stock dividend, stock split, combination of shares, recapitalization or
similar change in the capital structure of the Company or similar events with
respect to the partnership interests in the Partnership or (ii) any merger,
consolidation, spin-off, spin-out, split-off, split-up, reorganization,
partial or complete liquidation or other distribution of assets, issuance of
warrants


                                       5



or other rights to purchase securities or any other transaction or event
having an effect similar to any of the foregoing.

      6.    Compliance With Law. The Partnership and the Grantee will make
reasonable efforts to comply with all applicable securities laws. In addition,
notwithstanding any provision of this Agreement to the contrary, no LTIP OP
Units will become vested or be paid at a time that such vesting or payment
would result in a violation of any such law.

      7.    Investment Representation; Registration.

            (a)   The Grantee hereby makes the covenants, representations and
warranties and set forth on Annex D attached hereto. All of such covenants,
warranties and representations shall survive the execution and delivery of
this Agreement by the Grantee. The Grantee shall immediately notify the
Partnership upon discovering that any of the representations or warranties set
forth on Annex D were false when made or have, as a result of changes in
circumstances, become false.

            (b)   The Partnership may make a notation in its records and/or
affix a legend to the certificates (if any) representing the LTIP OP Units
issued pursuant to this Agreement to the effect that such units have not been
registered under the Securities Act of 1933 (the "Securities Act") and may
only be sold or transferred upon registration or pursuant to an exemption
therefrom.

            (c)   The Partnership will have no obligation to register under
the Securities Act any LTIP OP Units or any other securities issued pursuant
to this Agreement or upon conversion or exchange of LTIP OP Units.

      8.    Severability. In the event that one or more of the provisions of
this Agreement may be invalidated for any reason by a court, any provision so
invalidated will be deemed to be separable from the other provisions hereof,
and the remaining provisions hereof will continue to be valid and fully
enforceable.

      9.    Governing Law. This Agreement is made under, and will be construed
in accordance with, the laws of the State of New York, without giving effect
to the principle of conflict of laws of such State.

      10.   Transferability. This Agreement is personal to the Grantee, is
non-assignable and is not transferable in any manner, by operation of law or
otherwise, other than by will or the laws of descent and distribution.

      11.   Amendment. The Grantee acknowledges that this Agreement may be
amended or canceled by the Partnership for the purpose of satisfying changes
in law or for any other lawful purpose, provided that no such action shall
adversely affect the Grantee's rights under this Agreement without the
Grantee's written consent.


                                       6




      12.   No Obligation to Continue Employment. Neither the Company nor any
Affiliate is obligated by or as a result of this Agreement to continue the
Grantee in employment and this Agreement shall not interfere in any way with
the right of the Company or any Affiliate to terminate the employment of the
Grantee at any time.

      13.   Notices. Notices hereunder shall be mailed or delivered to the
Partnership at its principal place of business and shall be mailed or
delivered to the Grantee at the address on file with the Partnership or, in
either case, at such other address as one party may subsequently furnish to
the other party in writing.

      14.   Withholding and Taxes. No later than the date as of which an
amount first becomes includible in the gross income of the Grantee for income
tax purposes or subject to Federal Insurance Contributions Act withholding
with respect to any award under this Agreement, such Grantee will pay to the
Company or, if appropriate, any of its Affiliates, or make arrangements
satisfactory to the Committee regarding the payment of, any United States
federal, state or local or foreign taxes of any kind required by law to be
withheld with respect to such amount. The obligations of the Company under
this Agreement will be conditional on such payment or arrangements, and the
Company and its Affiliates shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment otherwise due to the Grantee.

      15.   Successors and Assigns. This Agreement shall be binding upon the
Partnership's successors and assigns, whether or not this Agreement is
expressly assumed.

            Company or any subsidiary where the stockholders of the Company,
            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),

      reasonable judgment, does not represent a promotion from or maintaining
      of Grantee's duties, responsibilities, status or positions as in effect
      immediately prior to the Change-in-Control, or any removal of Grantee
      from or any failure to reappoint or reelect Grantee to such positions,
      except in

      Grantee's continued participation in any of such benefit plans, programs
      or arrangements on at least as favorable a basis to Grantee as is the

      programs or arrangements or deprive Grantee of any material benefits
      enjoyed by Grantee at the time of the Change-in-Control.

                    FORM OF RECKSON ASSOCIATES REALTY CORP.
                          CHANGE-IN-CONTROL AGREEMENT


      WHEREAS, _______________ (the "Executive") is an executive officer of
Reckson Associates Realty Corp. (the "Company") or one of its Affiliates;

      WHEREAS, the Executive has received an award of LTIP OP Units (the "LTIP
OP Units") pursuant to the Long-Term Incentive Plan OP Unit Award Agreement,
dated as of ____ __, ____ between Executive, the Company and Reckson Operating
Partnership (the "LTIP Award Agreement"); and

      WHEREAS, the Company desires to provide the Executive with an additional
incentive in the event that a Change-in-Control occurs prior to the complete
book-up of the LTIP OP Units, thereby denying the Executive the intended
benefit of the LTIP OP Units awarded.

      NOW, THEREFORE, the Company and the Executive hereby agree as follows:

      1.    Change-in-Control Bonus:

      (a)   In the event the LTIP OP Units held by the Executive are redeemed
or otherwise cashed-out in connection with the occurrence of a
Change-in-Control, the Executive shall be entitled to receive from the Company
a cash bonus determined as follow:

            A = (B minus C), multiplied by D, where:

            A equals the amount of the cash bonus to be paid to the Executive
            by the Company;

            B equals the per OPU consideration received by a holder of an OPU
            in connection with the Change-in-Control;

            C equals the per vested LTIP OP Unit consideration received by the
            Executive in connection with the Change-in-Control (but in no
            event shall C be greater than B); and

            D equals the number of vested LTIP OP Units held by the Executive
            that are redeemed or otherwise cashed-out in connection with the
            Change-in-Control.

For example, if Executive holds 100 LTIP OP Units, all 100 LTIP OP Units are
vested or become vested in connection with Change-of Control, the LTIP OP
Units are cashed-out in connection with a Change-in-Control for $5 per LTIP OP
Unit, and the OPU are cashed-out for $7 per OPU, then Executive will be
entitled to receive a cash bonus of $200 hereunder ($7 minus $5, multiplied by
100).

      (b)   Said amount shall be payable in one lump sum payment no later than
31 days following the date the LTIP OP Units held by the Executive are

supplement the LTIP Award Agreement and the Employment Agreement.

      2.    Term. This Agreement shall terminate upon the earlier of (a) the
date on which the Executive no longer holds LTIP OP Units, other than as a
result of the redemption or other cash-out of such LTIP OP Units in connection
with the occurrence of a Change-in-Control, or (b) the payment of all amounts
owed hereunder to the Executive.

      3.    Governing Law. This Agreement is made under, and will be construed
in accordance with, the laws of the State of New York, without giving effect
to the principle of conflict of laws of such State.

      4.    Transferability. This Agreement is personal to the Executive, is
non-assignable and is not transferable in any manner, by operation of law or
otherwise, other than by will or the laws of descent and distribution.

      5.    Amendment. The Executive acknowledges that this Agreement may be
amended or canceled by the Company for the purpose of satisfying changes in
law or for any other lawful purpose, provided that no such action shall
adversely affect the Executive's rights under this Agreement without the
Executive's written consent.

      6.    No Obligation to Continue Employment. Neither the Company nor any
Affiliate is obligated by or as a result of this Agreement to continue the
Executive in employment and this Agreement shall not interfere in any way with
the right of the Company or any Affiliate to terminate the employment of the
Executive at any time.

      7.    Withholding and Taxes. No later than the date as of which an
amount first becomes includible in the gross income of the Executive for
income tax purposes or subject to Federal Insurance Contributions Act
withholding with respect to any award under this Agreement, such Executive
will pay to the Company or, if appropriate, any of its Affiliates, or make
arrangements satisfactory to the Company's Board of Directors regarding the
payment of, any United States federal, state or local or foreign taxes of any
kind required by law to be withheld with respect to such amount. The
obligations of the Company under this Agreement will be conditional on such
payment or arrangements, and the Company and its Affiliates shall, to the
extent permitted by law, have the right to deduct any such taxes from any
payment otherwise due to the Executive.

      8.    Successors and Assigns. This Agreement shall be binding upon the
Company's successors and assigns, whether or not this Agreement is expressly
assumed.

      9.    Definitions. Capitalized terms used but not otherwise defined

                                      OF
                         LIMITED PARTNERSHIP INTEREST

      In accordance with Sections 4.2 and 14.1.B (2), (3) and (4) of the

      NOW THEREFORE, in consideration of the mutual covenants contained

of which are hereby acknowledged, the parties hereto agree as follows:

Section 1. Issuance of LTIP Units

           (a) Pursuant to Section 4.2 of the Partnership Agreement, the
Partnership hereby issues 362,500 Partnership Interests (the "LTIP Units") to

limitations (including, but not limited to, limitations on transfer) of
Limited Partners under the Partnership Agreement, as supplemented and amended
by the rights, powers, privileges, restrictions, qualifications and
limitations specified in Exhibit I hereto.

           (b) The admission of the Grantees as Additional Limited Partners of

Section 2. Amendments to Partnership Agreement.


           Pursuant to Section 14.1.B(3) of the Partnership Agreement, the
General Partner, as general partner of the Partnership and as attorney-in-fact
for its Limited Partners, hereby amends the Partnership Agreement as follows:

           (a) Article 1 of the Partnership Agreement is hereby amended by
inserting the following definitions in alphabetical order:


           "Economic Capital Account Balance" has the meaning set forth in
           Section 6.1.E.

           "LTIP Units" means the units of the class of limited partnership
           interest initially issued on December 27, 2004, having the rights,
           powers, privileges, restrictions, qualifications and limitations
           set forth in the Supplement to the Partnership Agreement dated as
           of such date.

           "Common Unit Economic Balance" has the meaning set forth in Section
           6.1.E.

           (b) Section 6.1 of the Partnership Agreement is amended by
appending the following new paragraph E:

           E. Notwithstanding the provisions of Section 6.1.A above, but
           subject to the prior allocation of income and gain under clauses
           A(i), (ii) and (iii) above and to the terms of any Partnership Unit
           Designation in respect of any class of Partnership Interests
           ranking senior to the LTIP Units with respect to return of capital
           or any preferential or priority return, any Liquidating Gains shall
           first be allocated to the holders of LTIP Units until the Economic
           Capital Account Balances of such holders, to the extent
           attributable to their ownership of LTIP Units, are equal to (i) the
           Common Unit Economic Balance, multiplied by (ii) the number of
           their LTIP Units; provided that no such Liquidating Gains will be
           allocated with respect to any particular LTIP Unit unless and to
           the extent that the Common Unit Economic Balance exceeds the Common
           Unit Economic Balance in existence at the time such LTIP Unit was
           issued. For this purpose, "Liquidating Capital Gains" means net
           capital gains realized in connection with the actual or
           hypothetical sale of all or substantially all of the assets of the
           Partnership, including but not limited to net capital gain realized
           in connection with an adjustment to the Carrying Value of
           Partnership assets under Section 704(b) of the Code. The "Economic
           Capital Account Balances" of the holders of LTIP Units will be
           equal to their Capital Account balances, plus the amount of their
           shares of any Partner Minimum Gain or Partnership Minimum Gain, in
           either case to the extent attributable to their ownership of LTIP
           Units. Similarly, the


                                      2





           "Common Unit Economic Balance" shall mean (i) the Capital Account
           Balance of the Company, plus the amount of the Company's share of
           any Partner Minimum Gain or Partnership Minimum Gain, in either
           case to the extent attributable to the Company's ownership of
           Common Units and computed on a hypothetical basis after taking into
           account all allocations through the date on which any allocation is
           made under this Section 6.1.E, divided by (ii) the number of the
           Company's Common Units. Any such allocations shall be made among
           the LTIP Unitholders in proportion to the amounts required to be
           allocated to each under this Section 6.1.E. The parties agree that
           the intent of this Section 6.1.E is to make the Capital Account
           balance associated with each LTIP Unit economically equivalent to
           the Capital Account balance associated with the Company's Common
           Units (on a per-Unit basis), but only if the Capital Account
           balance associated with the Company's Common Units has increased on
           a per-Unit basis since the issuance of the relevant LTIP Unit.

           (c) Section 8.6A is hereby amended by appending the following
sentence:

           Notwithstanding the foregoing, the Redemption Right shall not be
           exercisable with respect to any Common Unit issued upon conversion
           of an LTIP Unit until on or after the date that is two years after
           the date on which the LTIP Unit was issued, provided however, that
           the foregoing restriction shall not apply if the Redemption Right
           is exercised by a LTIP Unit holder in connection with a transaction
           that falls within the definition of a "change-in-control" under the
           agreement or agreements to which the LTIP Units were issued to him
           or her.

           (d) The term "transfer" as used in Article 11 of the Partnership
Agreement shall not include any conversion of LTIP Units into Common Units.

           (e) Section 1.D(2) of Exhibit B to the Partnership Agreement is
hereby amended by replacing the text thereof with the following:

               (2)   Such adjustments shall be made as of the following
                     times: (a) immediately prior to the acquisition of an
                     additional interest in the partnership by any new or
                     existing Partner in exchange for more than a de
                     minimis Capital Contribution; (b) immediately prior to
                     the acquisition of a more than de minimis additional
                     interest in the Partnership by any new or existing
                     Partner as consideration for the provision of services
                     to or for the benefit of the Partnership in a partner
                     capacity or in anticipation of becoming a partner; (c)
                     immediately prior to the distribution by the
                     Partnership to a Partner of more than a de minimis
                     amount of property as consideration for an interest in
                     the Partnership; and (d) immediately prior to the
                     liquidation of the Partnership within the meaning of
                     Regulations Section 1.704-1(b)(2)(ii)(g), provided,
                     however,


                                       3





                     that adjustments pursuant to clauses (a), (b) and (c)
                     above shall be made only if the General Partner
                     determines that such adjustments are necessary or
                     appropriate to reflect the relative economic interests
                     of the Partners in the Partnership.

Section 3. Continuation of Partnership Agreement

           The Partnership Agreement and this Supplement shall be read
together and shall have the same force and effect as if the provisions of the
Partnership Agreement and this Supplement (including Exhibit I hereto) were
contained in one document. Any provisions of the Partnership Agreement not
amended by this Supplement shall remain in full force and effect as provided
in the Partnership Agreement immediately prior to the date hereof.

      IN WITNESS WHEREOF, the parties hereto have executed this Supplement to

                                   EXHIBIT I

                      RECKSON OPERATING PARTNERSHIP, L.P.

                DESIGNATION OF THE RIGHTS, POWERS, PRIVILEGES,
                 RESTRICTIONS, QUALIFICATIONS AND LIMITATIONS
                               OF THE LTIP UNITS

      The following are the terms of the LTIP Units established pursuant to
this Supplement:

      1. Number. The maximum number of authorized LTIP Units shall be 362,500.

      2. Vesting.

               (a) Vesting, Generally. LTIP Units may, in the sole discretion
of the General Partner, be issued subject to vesting, forfeiture and
additional restrictions on transfer pursuant to the terms of an award vesting
or other similar agreement (a "Vesting Agreement"). The terms of any Vesting
Agreement may be modified by the General Partner from time to time in its sole
discretion, subject to any restrictions on amendment imposed by the relevant
Vesting Agreement or by the terms of any plan pursuant to which the LTIP Units
are issued, if applicable. LTIP Units that have vested under the terms of a
Vesting Agreement are referred to as "Vested LTIP Units"; all other LTIP Units
shall be treated as "Unvested LTIP Units." Subject to the terms of any Vesting
Agreement, a holder of LTIP Units shall be entitled to transfer his or her
LTIP Units to the same extent, and subject to the same restrictions as holders
of Common Units are entitled to transfer their Common Units pursuant to
Article 11 of the Agreement.

               (b) Forfeiture or Transfer of Unvested LTIP Units. Unless
otherwise specified in the Vesting Agreement, upon the occurrence of any event
specified in a Vesting Agreement as resulting in either the right of the
Partnership or the Company to repurchase LTIP Units at a specified purchase
price or some other forfeiture of any LTIP Units, then if the Partnership or
the Company exercises such right to repurchase or upon the occurrence of the
circumstances resulting in such forfeiture, then the relevant LTIP Units shall
immediately, and without any further action, be treated as transferred to the
Company, if applicable, or cancelled and no longer outstanding for any
purpose. Unless otherwise specified in the Vesting Agreement, no consideration
or other payment shall be due with respect to any LTIP Units that have been
forfeited, other than any distributions declared with respect to a
Distribution Payment Record Date (as defined below) prior to the effective
date of the forfeiture. In connection with any repurchase or forfeiture of
LTIP Units, the balance of the portion of the Capital Account of the holder
that is attributable to all of his or her LTIP Units shall be reduced by the
amount, if any, by which it exceeds the target balance contemplated by Section
6.1.E of the Partnership Agreement, calculated with respect to the Holder's
remaining LTIP Units, if any.


                                   Exh. I-1





               (c) Legend. Any certificate evidencing an LTIP Unit shall bear
an appropriate legend indicating that additional terms, conditions and
restrictions on transfer, including without limitation any Vesting Agreement,
apply to the LTIP Unit.

      3. Distributions.

               (a) LTIP Distribution Amount. Commencing from the date on which
any LTIP Units are first issued (each, an "LTIP Issue Date"), for any
quarterly period holders of such LTIP Units shall be entitled to receive, if,
when and as authorized by the General Partner out of funds legally available
for the payment of distributions, cash distributions in an amount per unit
equal to the distribution payable on the Common Units for the corresponding
quarterly period (the "LTIP Distribution Amount"). Distributions on the LTIP
Units, if authorized, shall be payable quarterly in arrears on such dates as
may be authorized by the General Partner (any such date, a "Distribution
Payment Date"). In addition, LTIP Units shall be entitled to receive, if, when
and as authorized by the General Partner out of funds or other property
legally available for the payment of distributions, any special, extraordinary
or other distributions payable on the Common Units which may be made from time
to time in an amount per unit equal to the amount of any special,
extraordinary or other distributions payable on the Common Units.
Distributions will be payable to the holder of the LTIP Units with respect to
the LTIP Units held at the close of business on the applicable record date,
which shall be such date designated by the General Partner for the payment of
distributions that is not more than 30 nor less than 10 days prior to such
Distribution Payment Date (each, a "Distribution Payment Record Date"). With
regard to any distribution to the LTIP Units, the Distribution Payment Date
shall be the same date as the date fixed for the payment of distributions to
holders of Common Units and the Distribution Payment Record Date shall be the
same date set for the record date for holders of Common Units. In the event
that distributions to holders of Common Units for any period are paid on other
than a quarterly basis, for example, on a monthly basis, then distributions to
holders of the LTIP Units shall also be paid on that alternate basis.

               (b) Prohibited Distributions. No distributions on the LTIP
Units shall be authorized by the General Partner or be paid or set apart for
payment by the Partnership at such time as the terms and provisions of any
agreement of the Partnership, including any agreement relating to its
indebtedness, prohibits such authorization, payment or setting apart for
payment or provides that such authorization, payment or setting apart for
payment would constitute a breach thereof or a default thereunder, or if such
authorization or payment shall be restricted or prohibited by law.

               (c) Noncumulative Distributions. Distributions on the LTIP
Units will be noncumulative. If the General Partner does not authorize a
distribution on the LTIP Units payable on any Distribution Payment Date while
any LTIP Unit is outstanding, then the holder of the LTIP Units will have no
right to receive a distribution for that Distribution Payment Date, and the
Partnership will have no obligation to pay a distribution for that
Distribution Payment Date with respect to the LTIP Units.


                                   Exh. I-2





               (d) Parity with Common Units. No distributions, whether in
cash, securities or property, will be authorized or paid or set apart for
payment to holders of Common Units for any period unless for each LTIP Unit
outstanding, a distribution equal to the LTIP Distribution Amount with respect
to such period has been or contemporaneously is authorized and paid or
authorized and a sum sufficient for the payment thereof is set apart for such
payment to the holders of the LTIP Units for the then current distribution
period.

               (e) Definition of Set Apart for Payment. As used in this
Section 3, "set apart for payment" shall be deemed to include, without any
further action, the following: the recording by the Partnership in its
accounting ledgers of any accounting or bookkeeping entry which indicates,
pursuant to an authorization of a distribution by the General Partner, the
allocation of funds to be so paid on any series or class of units of the
Partnership.

      4. Adjustments.


The Partnership shall maintain at all times a one-to-one correspondence
between LTIP Units and Common Units for conversion, distribution and other
purposes, including without limitation complying with the following
procedures. If an Adjustment Event (as defined below) occurs, then the General
Partner shall make a corresponding adjustment to the LTIP Units to maintain a
one-for-one conversion and economic equivalence ratio between Common Units and
LTIP Units. The following shall be "Adjustment Events": (A) the Partnership
makes a distribution on all outstanding Common Units in Partnership Units, (B)
the Partnership subdivides the outstanding Common Units into a greater number
of units or combines the outstanding Common Units into a smaller number of
units, or (C) the Partnership issues any Partnership Units in exchange for its
outstanding Common Units by way of a reclassification or recapitalization of
its Common Units. If more than one Adjustment Event occurs, the adjustment to
the LTIP Units need be made only once using a single formula that takes into
account each and every Adjustment Event as if all Adjustment Events occurred
simultaneously. For the avoidance of doubt, the following shall not be
Adjustment Events: (x) the issuance of Partnership Units in a financing,
reorganization, acquisition or other similar business transaction, (y) the
issuance of Partnership Units pursuant to any employee benefit or compensation
plan or distribution reinvestment plan, or (z) the issuance of any Partnership
Units to the Company in respect of a capital contribution to the Partnership
of proceeds from the sale of securities by the Company. If the Partnership
takes an action affecting the Common Units other than actions specifically
described above as "Adjustment Events" and in the opinion of the General
Partner such action would require an adjustment to the LTIP Units to maintain
the one-to-one correspondence described above, the General Partner shall have
the right to make such adjustment to the LTIP Units, to the extent permitted
by law and by the terms of any plan pursuant to which the LTIP Units have been
issued, in such manner and at such time as the General Partner, in its sole
discretion, may determine to be appropriate under the circumstances. If an
adjustment is made to the LTIP Units as herein provided the Partnership shall
promptly file in the books and records of the Partnership an officer's
certificate setting forth such adjustment and a brief statement of


                                   Exh. I-3





the facts requiring such adjustment, which certificate shall be conclusive
evidence of the correctness of such adjustment absent manifest error. Promptly
after filing of such certificate, the Partnership shall mail a notice to each
holder of LTIP Units setting forth the adjustment to his or her LTIP Units and
the effective date of such adjustment.

      5. Ranking.

      The LTIP Units shall rank on parity with the Common Units in all
respects.

      6. No Liquidation Preference.

      The LTIP Units shall have no liquidation preference.

      7. Right to Convert LTIP Units into Common Units.

      The following provisions of this Section 7, the "OPU Conversion Right,"
shall apply from and after the date that the Board of Directors of the Company
elects, by formal resolution, to cause the OPU Conversion Right to apply.
Until such time, the following provisions of this Section 7 shall not apply,
and holders of LTIP Units shall instead have the redemption right contemplated
by Section 9.

               (a) Conversion Right. A holder of LTIP Units shall have the
right (the "Conversion Right"), at his or her option, at any time to convert
all or a portion of his or her Vested LTIP Units into Common Units; provided,
however, that a holder may not exercise the Conversion Right for fewer than
one thousand (1,000) Vested LTIP Units or, if such holder holds fewer than one
thousand Vested LTIP Units, all of the holder's Vested LTIP Units. Holders of
LTIP Units shall not have the right to convert Unvested LTIP Units into Common
Units until they become Vested LTIP Units; provided, however, that when a
holder of LTIP Units is notified of the expected occurrence of an event that
will cause his or her Unvested LTIP Units to become Vested LTIP Units, such
Person may give the Partnership a Conversion Notice conditioned upon and
effective as of the time of vesting, and such Conversion Notice, unless
subsequently revoked by the holder of the Units, shall be accepted by the
Partnership subject to such condition. The General Partner shall have the
right at any time to cause a conversion of Vested LTIP Units into Common
Units. In all cases, the conversion of any LTIP Units into Common Units shall
be subject to the conditions and procedures set forth in this Section 7.

               (b) Number of Units Convertible. A holder of Vested LTIP Units
may convert such Units into an equal number of fully paid and non-assessable
Common Units, giving effect to all adjustments (if any) made pursuant to
Section 4. Notwithstanding the foregoing, in no event may a holder of Vested
LTIP Units convert a number of Vested LTIP Units that exceeds (x) the Economic
Capital Account Balance of such holder, to the extent attributable to its
ownership of LTIP Units, divided by (y) the Common Unit Economic Balance, in
each case as determined as of the effective date of conversion (the "Capital
Account Limitation").


                                   Exh. I-4





               (c) Notice. In order to exercise his or her Conversion Right, a
holder of LTIP Units shall deliver a notice (a "Conversion Notice") in the
form attached as Exhibit A to this Supplement (with a copy to the General
Partner) not less than 10 nor more than 60 days prior to a date (the
"Conversion Date") specified in such Conversion Notice; provided, however,
that if the General Partner has not given to the LTIP Unitholders notice of a
proposed or upcoming Transaction (as defined below) at least thirty (30) days
prior to the effective date of such Transaction, then holders of LTIP Unit
shall have the right to deliver a Conversion Notice until the earlier of (x)
the tenth (10th) day after such notice from the General Partner of a
Transaction or (y) the third business day immediately preceding the effective
date of such Transaction. A Conversion Notice shall be provided in the manner
provided in Section 15.1 of the Partnership Agreement. Each Holder of LTIP
Units covenants and agrees with the Partnership that all Vested LTIP Units to
be converted pursuant to this Section 7 shall be free and clear of all liens.
Notwithstanding anything herein to the contrary, a Holder of LTIP Units may
deliver a Redemption Notice pursuant to Section 8.6 of the Partnership
Agreement relating to those Common Units that will be issued to such holder
upon conversion of such LTIP Units into Common Units in advance of the
Conversion Date; provided, however, that the redemption of such Common Units
by the Partnership shall in no event take place until the Conversion Date. For
clarity, it is noted that the objective of this paragraph is to put a holder
of LTIP Units in a position where, if he or she so wishes, the Common Units
into which his or her Vested LTIP Units will be converted can be redeemed by
the Partnership simultaneously with such conversion, with the further
consequence that, if the Company elects to assume the Partnership's redemption
obligation with respect to such Common Units under Section 8.6 of the
Partnership Agreement by delivering to such holder REIT Shares rather than
cash, then such holder can have such REIT Shares issued to him or her
simultaneously with the conversion of his or her Vested LTIP Units into Common
Units. The General Partner shall cooperate with a holder of LTIP Units to
coordinate the timing of the different events described in the foregoing
sentence.

               (d) Forced Conversion. The Partnership, at any time at the
election of the General Partner, may cause any number of Vested LTIP Units
held by a holder of LTIP Units to be converted (a "Forced Conversion") into an
equal number of Common Units, giving effect to all adjustments (if any) made
pursuant to Section 4; provided, that the Partnership may not cause Forced
Conversion of any LTIP Units that would not at the time be eligible for
conversion at the option of such LTIP Unitholder pursuant to paragraph (b)
above. In order to exercise its right of Forced Conversion, the Partnership
shall deliver a notice (a "Forced Conversion Notice") in the form attached as
Exhibit B to this Supplement to the applicable Holder not less than 10 nor
more than 60 days prior to the Conversion Date specified in such Forced
Conversion Notice. A Forced Conversion Notice shall be provided in the manner
provided in Section 15.1 of the Partnership Agreement.

               (e) Conversion Procedures. A conversion of Vested LTIP Units
for which the Holder has given a Conversion Notice or the Partnership has
given a Forced Conversion Notice shall occur automatically after the close of
business on the applicable Conversion Date without any action on the part of
such holder of LTIP Units, as of which


                                   Exh. I-5





time such holder of LTIP Units shall be credited on the books and records of
the Partnership with the issuance as of the opening of business on the next
day of the number of Common Units issuable upon such conversion. After the
conversion of LTIP Units as aforesaid, the Partnership shall deliver to such
holder of LTIP Units, upon his or her written request, a certificate of the
General Partner certifying the number of Common Units and remaining LTIP
Units, if any, held by such Person immediately after such conversion.

               (f) Treatment of Capital Account. For purposes of making future
allocations under Section 6.1.E of the Agreement and applying the Capital
Account Limitation, the portion of the Economic Capital Account balance of the
applicable holder of LTIP Units that is treated as attributable to his or her
LTIP Units shall be reduced, as of the date of conversion, by the product of
the number of LTIP Units converted and the Common Unit Economic Balance.

               (g) Mandatory Conversion in Connection with a Transaction. If
the Partnership or the General Partner shall be a party to any transaction
(including without limitation a merger, consolidation, unit exchange, self
tender offer for all or substantially all Common Units or other business
combination or reorganization, or sale of all or substantially all of the
Partnership's assets, but excluding any transaction which constitutes an
Adjustment Event), in each case as a result of which Common Units shall be
exchanged for or converted into the right, or the holders of such Units shall
otherwise be entitled, to receive cash, securities or other property or any
combination thereof (each of the foregoing being referred to herein as a
"Transaction"), then the General Partner shall, immediately prior to the
Transaction, exercise its right to cause a Forced Conversion with respect to
the maximum number of LTIP Units then eligible for conversion, taking into
account any allocations that occur in connection with the Transaction or that
would occur in connection with the Transaction if the assets of the
Partnership were sold at the Transaction price or, if applicable, at a value
determined by the General Partner in good faith using the value attributed to
the Partnership Units in the context of the Transaction (in which case the
Conversion Date shall be the effective date of the Transaction).

      In anticipation of such Forced Conversion and the consummation of the
Transaction, the Partnership shall use commercially reasonable efforts to
cause each holder of LTIP Units to be afforded the right to receive in
connection with such Transaction in consideration for the Common Units into
which his or her LTIP Units will be converted the same kind and amount of
cash, securities and other property (or any combination thereof) receivable
upon the consummation of such Transaction by a holder of the same number of
Common Units, assuming such holder of Common Units is not a Person with which
the Partnership consolidated or into which the Partnership merged or which
merged into the Partnership or to which such sale or transfer was made, as the
case may be (a "Constituent Person"), or an affiliate of a Constituent Person.
In the event that holders of Common Units have the opportunity to elect the
form or type of consideration to be received upon consummation of the
Transaction, prior to such Transaction the General Partner shall give prompt
written notice to each holder of LTIP Units of such


                                   Exh. I-6





election, and shall use commercially reasonable efforts to afford such holders
the right to elect, by written notice to the General Partner, the form or type
of consideration to be received upon conversion of each LTIP Unit held by such
holder into Common Units in connection with such Transaction. If a holder of
LTIP Units fails to make such an election, such Holder (and any of its
transferees) shall receive upon conversion of each LTIP Unit held him or her
(or by any of his or her transferees) the same kind and amount of
consideration that a holder of a Common Unit would receive if such Common Unit
Holder failed to make such an election.

      Subject to the rights of the Partnership and the General Partner under
any Vesting Agreement and the terms of any plan under which LTIP Units are
issued, the Partnership shall use commercially reasonable effort to cause the
terms of any Transaction to be consistent with the provisions of this Section
7 and to enter into an agreement with the successor or purchasing entity, as
the case may be, for the benefit of any holders of LTIP Units whose LTIP Units
will not be converted into Common Units in connection with the Transaction
that will (i) contain provisions enabling the holders of LTIP Units that
remain outstanding after such Transaction to convert their LTIP Units into
securities as comparable as reasonably possible under the circumstances to the
Common Units and (ii) preserve as far as reasonably possible under the
circumstances the distribution, special allocation, conversion, and other
rights set forth in the Partnership Agreement for the benefit of the holders
of LTIP Units.

      8. Redemption at the Option of the Partnership.

      LTIP Units will not be redeemable at the option of the Partnership;
provided, however, that the foregoing shall not prohibit the Partnership from
repurchasing LTIP Units from the holder thereof if and to the extent such
holder agrees to sell such Units.

      9. Redemption at Holder's Election.

           The following provisions of this Section 9 shall apply until the
date that the OPU Conversion Right becomes effective as contemplated by
Section 7 above. From and after such date, the following provisions shall not
apply, and holders of LTIP Units shall instead have the OPU Conversion Right
contemplated by Section 7:

               (a) Redemption Right. On or after the date that is the later of
(i) two (2) years after the LTIP Issuance Date of any Vested LTIP Unit and
(ii) six (6) months after the date on which such Vested LTIP Unit became a
Vested LTIP Unit, other than in connection with a change-in-control
transaction, the holder of any such Vested LTIP Unit shall have the right (the
"Redemption Right") to require the Partnership to redeem on a Specified
Redemption Date all or a portion of the LTIP Units held by such Limited
Partner at a redemption price per LTIP Unit equal to and in the form of the
Cash Amount to be paid by the Partnership. The Redemption Right shall be
exercised pursuant to a Notice of Redemption delivered to the Partnership in
the form attached as Exhibit C hereto (with a copy to the Company) by the
Limited Partner who is exercising the redemption right (the "Redeeming
Partner"). A Limited Partner may not exercise the Redemption Right for less
than one thousand (1,000) Vested LTIP Units at any one time


                                   Exh. I-7





or, if such Limited Partner holds less than one thousand (1,000) Vested LTIP
Units, all of the Vested LTIP Units held by such Partner. The Redeeming
Partner shall have no right, with respect to any Partnership Units so
redeemed, to receive any distributions paid on or after the Specified
Redemption Date. The Assignee of any Limited Partner may exercise the rights
of such Limited Partner pursuant to this Section 9, and such Limited Partner
shall be deemed to have assigned such rights to such Assignee and shall be
bound by the exercise of such rights by such Assignee. In connection with any
exercise of such rights by an Assignee on behalf of a Limited Partner, the
Cash Amount shall be paid by the Partnership directly to such Assignee and not
to such Limited Partner. Any LTIP Units redeemed by the Partnership pursuant
to this Section 9 shall be cancelled upon such redemption.

      For purposes of clarification, it is understood that the Cash Amount at
the date of this Supplement is based upon a Conversion Factor of 1.0 and that
such Conversion Factor may be adjusted from time to time as provided in the
Partnership Agreement.

               (b) Number of Units Redeemable. Notwithstanding the foregoing
provisions of paragraph (a), in no event may a holder of Vested LTIP Units
redeem a number of Vested LTIP Units that exceeds (x) the Economic Capital
Account Balance of such holder to the extent attributable to its ownership of
LTIP Units, divided by (y) the Common Unit Economic Balance, in each case as
determined as of the effective date of the redemption.

               (c) Treatment of Capital Account. For purposes of making future
allocations under Section 6.1.E of the Agreement and applying the Capital
Account Limitation, the portion of the Economic Capital Account balance of the
applicable holder of LTIP Units that is treated as attributable to his or her
LTIP Units shall be reduced, as of the date of conversion, by the product of
the number of LTIP Units converted and the Common Unit Economic Balance.

      10. Voting Rights.

               (a) Voting with Common Units. Holders of LTIP Units shall have
the right to vote on all matters submitted to a vote of the holders of Common
Units; holders of LTIP Units and Common Units shall vote together as a single
class, together with any other class or series of units of limited partnership
interest in the Partnership upon which like voting rights have been conferred.
In any matter in which the LTIP Units are entitled to vote, including an
action by written consent, each LTIP Unit shall be entitled to one vote.

               (b) Special Approval Rights. In addition to, and not in
limitation of, the provisions of Section 10(a) above (and notwithstanding
anything appearing to be contrary in the Partnership Agreement), the Company
and/or the Partnership shall not, without the affirmative consent of the
holders of sixty-six and two-thirds percent (66 2/3%) of the then outstanding
LTIP Units, given in person or by proxy, either in writing or at a meeting,
take any action that would materially and adversely alter, change, modify or
amend the rights, powers or privileges of the LTIP Units; but subject in any
event to the following provisions: (i) no consent of the holders of LTIP Units
will be required if and to the extent that any such alteration, change,
modification or amendment would similarly alter, change, modify


                                   Exh. I-8





or amend the rights, powers or privileges of the Common Units; (ii) with
respect to the occurrence of any merger, consolidation or other business
combination or reorganization, so long as the LTIP Units remain outstanding
with the terms thereof materially unchanged or, if the Partnership is not the
surviving entity in such transaction, are exchanged for a security of the
surviving entity with terms that are materially the same with respect to
rights to allocations, distributions, redemption, conversion and voting as the
LTIP Units and without any income, gain or loss expected to be recognized by
the holder upon the exchange for federal income tax purposes (and with the
terms of the Common Units or such other securities into which the LTIP Units
(or the substitute security therefor) are convertible materially the same with
respect to rights to allocations, distributions, redemption, conversion and
voting), the occurrence of any such event shall not be deemed to materially
and adversely alter, change, modify or amend the rights, powers or privileges
of the LTIP Units; (iii) any creation or issuance of any Common Units or of
any class of series of common or preferred units of the Partnership (whether
ranking junior to, on a parity with or senior to the LTIP Units with respect
to payment of distributions, redemption rights and the distribution of assets
upon liquidation, dissolution or winding up), which either (x) does not
require the consent of the holders of Common Units or (y) does require such
consent and is authorized by a vote of the holders of Common Units; and LTIP
Units voting together as a single class, together with any other class or
series of units of limited partnership interest in the Partnership upon which
like voting rights have been conferred, shall not be deemed to materially and
adversely alter, change, modify or amend the rights, powers or privileges of
the LTIP Units; and (iv) any waiver by the Partnership of restrictions or
limitations applicable to any outstanding LTIP Units with respect to any
holder or holders thereof shall not be deemed to materially and adversely
alter, change, modify or amend the rights, powers or privileges of the LTIP
Units with respect to other holders. The foregoing voting provisions will not
apply if, as of or prior to the time when the action with respect to which
such vote would otherwise be required will be taken or be effective, all
outstanding LTIP Units shall have been converted and/or redeemed, or provision
is made for such redemption and/or conversion to occur as of or prior to such
time.
