          2. Registration Under the Securities Act.
             -------------------------------------

          (a) Shelf Registration. The Company shall file or cause to be filed,
              ------------------
on or prior to December 2, 1999, a Shelf Registration Statement providing for
the sale by the Holders of all of the Registrable Securities and shall use its
best efforts to have such Shelf Registration Statement declared effective by the
SEC as promptly as practicable after filing thereof. No Holder of Registrable
Securities shall be entitled to include any of its Registrable Securities in any
Shelf Registration pursuant to this Agreement unless and until such Holder
agrees in writing to be bound by all of the provisions of this Agreement
applicable to such Holder and furnishes to the Company in writing, within 15
days after receipt of a request therefor, such information as the Company may,
after conferring with counsel with regard to information relating to Holders
that would be required by the SEC to be included in such Shelf Registration
Statement or Prospectus included therein, reasonably request for inclusion in
any Shelf Registration Statement or Prospectus included therein. Each Holder as
to which any Shelf Registration is being effected agrees to furnish to the
Company all information with respect to such Holder necessary to make the
information previously furnished to the Company by such Holder not materially
misleading.

          The Company agrees to use its best efforts to keep the Shelf
Registration Statement continuously effective and the Prospectus usable for
resales during the Rule 144(k) Period (subject to extension pursuant to the last
paragraph of Section 3 hereof), or for such shorter period which will terminate
when all of the Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement or cease to be Registrable
Securities (the "Effectiveness Period"); provided, however, that for 60 days or
less (whether or not consecutive) in any twelve-month period, the Company shall
be permitted to suspend sales of Securities if the Shelf Registration Statement
is no longer effective or the Prospectus usable for resales due to circumstances
relating to pending developments, public filings with the SEC and similar
events, or because the Prospectus includes an untrue statement of a material
fact or omits to state a material fact necessary in order to make statements
therein, in the light of the circumstances under which they were made, not
misleading. The Company will, in the event a Shelf Registration Statement is
declared effective, provide to each Holder a reasonable number of copies of the
Prospectus which is a part of the Shelf Registration Statement, notify each such
Holder when the Shelf Registration Statement has become effective and take such
other actions as are required to permit unrestricted resales of the Registrable
Securities. The Company further agrees to supplement or amend the Shelf
Registration Statement if and as required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company agrees to
furnish to the Holders of Registrable Securities copies of any such supplement
or amendment promptly after its being used or filed with the SEC.

          (b) Expenses. The Company, as issuer of the Securities, shall pay all
              --------
Registration Expenses in connection with any Shelf Registration Statement filed
pursuant to Section 2(a) hereof and will reimburse any single counsel designated
in writing by the Majority Holders to act as counsel for the Holders of the
Registrable Securities in connection with a Shelf Registration Statement, which
other counsel shall be reasonably satisfactory to the Company. Except as
provided herein, each Holder shall pay all expenses of its counsel, underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Shelf
Registration Statement.

          (c) Effective Shelf Registration Statement. A Shelf Registration
              --------------------------------------
Statement will not be deemed to have become effective unless it has been
declared effective by the SEC; provided, however, that if, after it has been
declared effective, the offering of Registrable Securities pursuant to such
Shelf Registration Statement is interfered with by any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or court,
such Shelf Registration Statement will be deemed not to have been effective
during the period of such interference, until the offering of Registrable
Securities pursuant to such Shelf Registration Statement may legally resume. The
Company will be deemed not to have used its reasonable best efforts to cause a
Shelf Registration Statement to become, or to remain, effective during the
requisite period if it voluntarily takes any action that would result in any
such Shelf Registration Statement not being declared effective or that would
result in the Holders of Registrable Securities covered thereby not being able
to offer and sell such Registrable Securities during that period, unless such
action is required by applicable law.

          (d) Liquidated Damages. In the event that:
              ------------------

               (i) a Shelf Registration Statement is not filed with the SEC on
or prior to December 2, 1999, then liquidated damages ("Liquidated Damages")
shall accumulate on the liquidation preference of the Preferred Securities at a
rate of 0.25% per annum;

               (ii) a Shelf Registration Statement is not declared effective by
the SEC on or prior to the 90th day after the date such Shelf Registration
Statement was initially filed with the SEC, then Liquidated Damages shall
accumulate on the liquidation preference of the Preferred Securities at a rate
of 0.25% per annum; or

               (iii) a Shelf Registration Statement has been declared effective
and such Shelf Registration Statement ceases to be effective or the Prospectus
usable for resales (A) at any time prior to the expiration of the Effectiveness
Period and (B) if related to corporate developments, public filings with the SEC
or similar events or to correct a material misstatement or omission in the
Prospectus contained in the Shelf Registration Statement, for more than 60 days
(whether or not consecutive) in any twelve-month period, then, following the day
or 60th day, as the case may be, such Shelf Registration Statement ceases to be
effective or the Prospectus usable for resales, Liquidated Damages shall
accumulate on the liquidation preference of the Preferred Securities at a rate
of 0.25% per annum;

provided, however, that the Liquidated Damages rate on the liquidation
preference of the Preferred Securities may not exceed in the aggregate 0.25% per
annum; provided, further, however, that (1) upon the filing of a Shelf
Registration Statement (in the case of clause (i) above), (2) upon the
effectiveness of a Shelf Registration Statement (in the case of clause (ii)
above), or (3) upon such time as the Shelf Registration Statement which had
ceased to remain effective or the Prospectus usable for resales again becomes
effective and usable for resales (in the case of clause (iii) above), Liquidated
Damages on the liquidation preference of the Preferred Securities as a result
thereof shall cease to accumulate.

          Any amounts of Liquidated Damages due pursuant to Section 2(d)(i),
(ii) or (iii) above will be payable in cash on the next succeeding January 31,
April 30, July 31 or October 31, as the case may be, to Holders on the relevant
record dates for the payment of distributions.

          (e) Specific Enforcement. Without limiting the remedies available to
              --------------------
the Holders, the Company acknowledges that any failure by it to comply with its
obligations under Section 2(a) hereof may result in material irreparable injury
to the Holders for which there is no adequate remedy at law, that it would not
be possible to measure damages for such injuries precisely and that, in the
event of any such failure, any Holder may obtain such relief as may be required
to specifically enforce the Company's obligations under Section 2(a) hereof.

          3. Registration Procedures. In connection with the obligations of the
             -----------------------
Company with respect to the Shelf Registration Statement pursuant to Section
2(a) hereof, the Company shall use its best efforts to:

          (a) prepare and file with the SEC a Shelf Registration Statement as
     prescribed by Section 2(a) hereof within the relevant time period specified
     in Section 2(a) hereof on the appropriate form under the Securities Act,
     which form shall (i) be selected by the Company, (ii) be available for the
     sale of the Registrable Securities by the selling Holders thereof, and
     (iii) comply as to form in all material respects with the requirements of
     the applicable form and include all financial statements required by the
     SEC to be filed therewith; the Company shall use its best efforts to cause
     such Shelf Registration Statement to become effective and remain effective
     and the Prospectus usable for resales in accordance with Section 2 hereof;
     provided, however, that, before filing any Shelf Registration Statement or
     Prospectus or any amendments or supplements thereto, the Company shall
     furnish to and afford the Holders of the Registrable Securities covered by
     such Shelf Registration Statement, their counsel and the managing
     underwriters, if any, a reasonable opportunity to review copies of all such
     documents (including copies of any documents to be incorporated by
     reference therein and all exhibits thereto) proposed to be filed; and the
     Company shall not file any Shelf Registration Statement or Prospectus or
     any amendments or supplements thereto in respect of which the Holders must
     be afforded an opportunity to review prior to the filing of such document,
     other than filings required under the Exchange Act, if the Majority
     Holders, their counsel or the managing underwriters, if any, shall
     reasonably object in a timely manner;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to the Shelf Registration Statement as may be necessary to keep
     such Shelf Registration Statement effective for the Effectiveness Period,

     and cause each Prospectus to be supplemented, if so determined by the
     Company or requested by the SEC, by any required prospectus supplement and

     provision then in force) under the Securities Act, and comply with the
     provisions of the Securities Act, the Exchange Act and the rules and
     regulations promulgated thereunder applicable to it with respect to the

          (c) (i) notify each Holder of Registrable Securities included in the

     Registrable Securities will be made in accordance with the method selected
     by the Majority Holders, (ii) furnish to each Holder of Registrable
     Securities included in the Shelf Registration Statement and to each
     underwriter of an underwritten offering of Registrable Securities, if any,

     preliminary prospectus, and any amendment or supplement thereto, and such
     other documents as such Holder or underwriter may reasonably request, in
     order to facilitate the public sale or other disposition of the Registrable
     Securities and (iii) consent to the use of the Prospectus or any amendment
     or supplement thereto by each of the selling Holders of Registrable
     Securities included in the Shelf Registration Statement in connection with
     the offering and sale of the Registrable Securities covered by the
     Prospectus or any amendment or supplement thereto;

          (d) register or qualify the Registrable Securities under all
     applicable state securities or "blue sky" laws of such jurisdictions by the
     time the applicable Shelf Registration Statement is declared effective by
     the SEC as any Holder of Registrable Securities covered by a Shelf
     Registration Statement and each underwriter of an underwritten offering of
     Registrable Securities shall reasonably request in writing in advance of
     such date of effectiveness, and do any and all other acts and things which
     may be reasonably necessary or advisable to enable such Holder and
     underwriter to consummate the disposition in each such jurisdiction of such
     Registrable Securities owned by such Holder; provided, however, that the

     respects, (v) of the happening of any event or the failure of any event to
     occur or the discovery of any facts, during the Effectiveness Period, which

     Statement and the managing underwriters) customary for such agreements with
     respect to all parties to be indemnified pursuant to said Section
     (including, without limitation, such underwriters and selling Holders); and
     in the case of an underwritten registration, the above requirements shall

     generally available to the public through no fault of an Inspector or a
     selling Holder; and each selling Holder of such Registrable Securities will
     be required to further agree in writing that it will, upon learning that
     disclosure of such Records or information is sought in a court of competent
     jurisdiction, or in connection with any action, suit or proceeding, give
     notice to the Company and allow the Company at its expense to undertake
     appropriate action to prevent disclosure of the Records and information
     deemed confidential;

          (n) comply with all applicable rules and regulations of the SEC so
     long as any provision of this Agreement shall be applicable and make
     generally available to its securityholders earning statements satisfying
     the provisions of Section 11(a) of the Securities Act and Rule 158
     thereunder (or any similar rule promulgated under the Securities Act) no
     later than 45 days after the end of any twelve-month period (or 90 days
     after the end of any twelve-month period if such period is a fiscal year)
     (i) commencing at the end of any fiscal quarter in which Registrable
     Securities are sold to underwriters in a firm commitment or best efforts
     underwritten offering and (ii) if not sold to underwriters in such an
     offering, commencing on the first day of the first fiscal quarter of the
     Company after the effective date of a Shelf Registration Statement, which
     statements shall cover said twelve-month periods, provided that the
     obligations under this Section 3(n) shall be satisfied by the timely filing
     of quarterly and annual reports on Forms 10-Q and 10-K under the Exchange
     Act;

          (o) cooperate with each seller of Registrable Securities covered by a
     Shelf Registration Statement and each underwriter, if any, participating in
     the disposition of such Registrable Securities and their respective counsel
     in connection with any filings required to be made with the NASD;

          (p) take all other steps necessary to effect the registration of the
     Registrable Securities covered by a Shelf Registration Statement
     contemplated hereby; and (q) the Company may require each seller of
     Registrable Securities as to which any registration is being effected to
     furnish to it such information regarding such seller as may be required by
     the staff of the SEC to be included in a Shelf Registration Statement; the
     Company may exclude from such registration the Registrable Securities of
     any seller who unreasonably fails to furnish such information within a
     reasonable time after receiving such request; and the Company shall have no
     obligation to register under the Securities Act the Registrable Securities
     of a seller who so fails to furnish such information.

          Each Holder agrees that, upon receipt of any notice from the Company
of the occurrence of any event specified in Section 3(e)(ii), 3(e)(iii), 3(e)(v)
or 3(e)(vi) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Shelf Registration Statement until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, if so directed by the Company, such Holder will deliver to the
Company (at the Company's expense) all copies in such Holder's possession, other
than permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice to suspend the disposition of
Registrable Securities pursuant to a Shelf Registration Statement, the Company
shall use its best efforts to file and have declared effective (if an amendment)
as soon as practicable after the resolution of the related matters an amendment
or supplement to the Shelf Registration Statement and related Prospectus and
shall extend the period during which such Shelf Registration Statement is
required to be maintained effective and the Prospectus usable for resales
pursuant to this Agreement by the number of days in the period from and
including the date of the giving of such notice to and including the date when
the Company shall have made available to the Holders (x) copies of the
supplemented or amended Prospectus necessary to resume such dispositions or (y)
the Advice.

          4. Indemnification and Contribution. (a) The Company and the Operating
             --------------------------------
Partnership hereby agree, jointly and severally, to indemnify and hold harmless
each Holder, each underwriter who participates in an offering of the Registrable
Securities, each Person, if any, who controls any of such parties within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act
and each of their respective directors, officers, employees and agents, as
follows:

               (i) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, arising out of any untrue statement
          or alleged untrue statement of a material fact contained in a Shelf
          Registration Statement (or any amendment thereto) or the Prospectus
          (or any amendment or supplement thereto) or the omission or alleged
          omission therefrom of a material fact required to be stated therein,
          in the light of the circumstances under which they were made, not
          misleading;

               (ii) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, to the extent of the aggregate amount
          paid in settlement of any litigation, or any investigation or
          proceeding by any governmental agency or body, commenced or
          threatened, or of any claim whatsoever based upon any such untrue
          statement or omission, or any such alleged untrue statement or
          omission, provided that (subject to Section 4(d) hereof) such
          settlement is effected with the prior written consent of the Company
          and the Operating Partnership; and

               (iii) against any and all expenses whatsoever, as incurred
          (including the reasonable fees and disbursements of counsel chosen by
          such Holder), reasonably incurred in investigating, preparing or
          defending against any litigation, or any investigation or proceeding
          by any governmental agency or body, commenced or threatened, or any
          claim whatsoever based upon any such untrue statement or omission, or
          any such alleged untrue statement or omission, to the extent that any
          such expense is not paid under subparagraph (i) or (ii) of this
          Section 4(a);

provided, however, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with written information furnished in writing to the Company and the
Operating Partnership by such Holder or underwriter for use in the Shelf
Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto).

          (b) The Initial Purchasers and each Holder or underwriter agrees,
severally and not jointly, to indemnify and hold harmless the Company, its
trustees and officers (including each officer of the Company who signed the
Shelf Registration Statement), and the Operating Partnership and each Person, if
any, who controls the Company within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act against any and all loss, liability,
claim, damage and expense whatsoever described in the indemnity contained in
Section 4(a) hereof, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Shelf
Registration Statement (or any amendment thereto) or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company by such Holder expressly for use in such
Shelf Registration Statement (or any amendment thereto) or such Prospectus (or
any amendment or supplement thereto); provided, however, that no Holder shall be
liable for any claims hereunder in excess of the amount of net proceeds received
by such Holder from the sale of Registrable Securities.

          (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
which it may have under this Section 4 to the extent that it is not materially
prejudiced by such failure as a result thereof, and in any event shall not
relieve it from liability which it may have otherwise on account of this
indemnity agreement. In the case of parties indemnified pursuant to Section 4(a)
or (b) above, counsel to the indemnified parties shall be selected by such
parties. An indemnifying party may participate at its own expense in the defense
of such action; provided, however, that counsel to the indemnifying party shall
not (except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for the
fees and expenses of more than one counsel (in addition to local counsel),
separate from their own counsel, for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 4 (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional written release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

          (d) If at any time an indemnified party shall have validly requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

          (e) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement set forth in this Section 4 is
for any reason held to be unenforceable by an indemnified party although
applicable in accordance with its terms, the Company and the Operating
Partnership, on the one hand, and the Holders, on the other hand, shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by such indemnity agreement incurred by the Company, the
Operating Partnership and the Holders, as incurred; provided, however, that no
Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any Person that
was not guilty of such fraudulent misrepresentation. As between the Company and
the Operating Partnership, on the one hand, and the Holders, on the other hand,
such parties shall contribute to such aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement in
such proportion as shall be appropriate to reflect the relative fault of the
Company and the Operating Partnership, on the one hand, and the Holders, on the
other hand, with respect to the statements or omissions which resulted in such
loss, liability, claim, damage or expense, or action in respect thereof, as well
as any other relevant equitable considerations. The relative fault of the
Company and the Operating Partnership, on the one hand, and of the Holders, on
the other hand, shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Operating Partnership, on the one hand, or by or on behalf of the
Holders, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the Operating Partnership and the Holders of the Registrable
Securities agree that it would not be just and equitable if contribution
pursuant to this Section 4 were to be determined by pro rata allocation or by
any other method of allocation that does not take into account the relevant
equitable considerations. For purposes of this Section 4, each Affiliate of a
Holder, and each director, officer and employee and Person, if any, who controls
a Holder or such Affiliate within the meaning of Section 15 of the Securities
Act shall have the same rights to contribution as such Holder, and each trustee
and officer of the Company and each Person, if any, who controls the Company
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act shall have the same rights to contribution as the Company and the
Operating Partnership.

          5. Participation in an Underwritten Registration. No Holder may
             ---------------------------------------------
participate in an underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's Registrable Securities on the basis provided in the
underwriting arrangement approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and
other documents reasonably required under the terms of such underwriting
arrangements.

          6. Selection of Underwriters. The Holders of Registrable Securities
             -------------------------
covered by the Shelf Registration Statement who desire to do so may sell the
Securities covered by such Shelf Registration in an underwritten offering,
subject to the provisions of Section 3(l) hereof. In any such underwritten
offering, the underwriter or underwriters and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate liquidation preference of the Registrable Securities included in such
offering; provided, however, that such underwriters and managers must be
reasonably satisfactory to the Company.

          7. Miscellaneous.
             -------------

          (a) Rule 144. For so long as the Company is subject to the reporting
              --------
requirements of Section 13 or 15 of the Exchange Act and any Registrable
Securities remain outstanding, the Company will file the reports required to be
filed by it under the Securities Act and Section 13(a) or 15(d) of the Exchange
Act and the rules and regulations adopted by the SEC thereunder; provided,
however, that if the Company ceases to be so required to file such reports, it
will, upon the request of any Holder of Registrable Securities (a) make publicly
available such information as is necessary to permit sales of its securities
pursuant to Rule 144 under the Securities Act and (b) take such further action
that is reasonable in the circumstances, in each case, to the extent required
from time to time to enable such Holder to sell its Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 under the Securities Act, as such rule may be
amended from time to time, or any similar rules or regulations hereafter adopted
by the SEC. Upon the request of any Holder of Registrable Securities, the
Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

          (b) No Inconsistent Agreements. The Company has not entered into, and
              --------------------------
will not enter into, any agreement which is inconsistent with the rights granted
to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's other issued and outstanding
securities under any such agreements.

          (c) Amendments and Waivers. The provisions of this Agreement,
              ----------------------
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of Holders
of a majority in aggregate liquidation preference of the outstanding Registrable
Securities affected by such amendment, modification, supplement, waiver or
departure; provided that no amendment, modification or supplement or waiver or
consent to the departure with respect to the provisions of Section 4 hereof
shall be effective as against any Holder of Registrable Securities unless
consented to in writing by such Holder of Registrable Securities.
Notwithstanding the foregoing sentence, (i) this Agreement may be amended,
without the consent of any Holder of Registrable Securities, by written
agreement signed by the Company, the Operating Partnership and the Initial
Purchasers, to cure any ambiguity, correct or supplement any provision of this
Agreement that may be inconsistent with any other provision of this Agreement or
to make any other provisions with respect to matters or questions arising under
this Agreement which shall not be inconsistent with other provisions of this
Agreement, (ii) this Agreement may be amended, modified or supplemented, and
waivers and consents to departures from the provisions hereof may be given, by
written agreement signed by the Company, the Operating Partnership and the
Initial Purchasers to the extent that any such amendment, modification,
supplement, waiver or consent is, in their reasonable judgment, necessary or
appropriate to comply with applicable law (including any interpretation of the
Staff of the SEC) or any change therein and (iii) to the extent any provision of
this Agreement relates to the Initial Purchasers, such provision may be amended,
modified or supplemented, and waivers or consents to departures from such
provisions may be given, by written agreement signed by the Initial Purchasers,
the Operating Partnership and the Company.

          (d) Notices. All notices and other communications provided for or
              -------
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 7(d), which address initially is, with respect to the Initial
Purchasers, the address set forth in the Purchase Agreement; and (ii) if to the
Company or the Operating Partnership, initially at the Company's address set
forth in the Purchase Agreement and thereafter at such other address, notice of
which is given in accordance with the provisions of this Section 7(d).

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

          (e) Successors and Assigns. This Agreement shall inure to the benefit
              ----------------------
of and be binding upon the successors, assigns and transferees of the Initial
Purchasers, including, without limitation and without the need for an express
assignment, subsequent Holders; provided, however, that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement or amended
charter of the Company. If any transferee of any Holder shall acquire
Registrable Securities, in any manner, whether by operation of law or otherwise,
such Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

          (f) Third Party Beneficiaries. Each Holder shall be a third party
              -------------------------
beneficiary of the agreements made hereunder among the Company, the Operating
Partnership and the Initial Purchasers, and the Initial Purchasers shall have
the right to enforce such agreements directly to the extent it deems such
enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

          (g) Counterparts. This Agreement may be executed in any number of
              ------------
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h) Headings. The headings in this Agreement are for convenience of
              --------
reference only and shall not limit or otherwise affect the meaning hereof.

          (i) Governing Law. This Agreement shall be governed by and construed
              -------------
in accordance with the laws of the State of New York without giving effect to
any provisions relating to conflicts of laws.

          (j) Severability. In the event that any one or more of the provisions
              ------------
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

          (k) Securities Held by the Company or its Affiliates. Whenever the
              ------------------------------------------------
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
any Affiliates shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.



          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

                                   Very truly yours,

                                   RECKSON ASSOCIATES REALTY CORP.
