restrictions and conditions set forth herein, in the Plan and in the Partnership

     1.   ACCEPTANCE OF AGREEMENT. The Grantee shall have no rights with respect

the close of business on the Final Acceptance Date specified above by (i) making
a contribution to the capital of the Partnership by certified or bank check or

Grantee shall have all the rights of a Limited Partner of the Partnership with
respect to the number of LTIP Units specified above, as set forth in the
Partnership Agreement, subject, however, to the restrictions and conditions
specified in Paragraph 2 below.

     2.   RESTRICTIONS AND CONDITIONS.

          (a)  The records of the Partnership evidencing the LTIP Units granted
herein shall bear an appropriate legend, as determined by the Partnership in its
sole discretion, to the effect that such LTIP Units are subject to restrictions
as set forth herein, in the Plan and in the Partnership Agreement.

          (b)  LTIP Units granted herein may not be sold, assigned, transferred,
pledged or otherwise encumbered or disposed of by the Grantee prior to vesting.

          (c)  If the Grantee ceases to be a Director of the Company for any
reason, subject to Section 13 of the Plan, prior to vesting of the LTIP Units
granted herein, the Partnership shall have the right, at the discretion of the
Administrator, to repurchase such LTIP Units from the Grantee or the Grantee's
legal representative at the Purchase Price per Unit. The Partnership must
exercise such right of repurchase or forfeiture by written notice to the Grantee
or the Grantee's legal representative not later than 90 days following such
cessation of Grantee's tenure as Director.

     3.   VESTING OF LTIP UNITS. The restrictions and conditions in Paragraph 2
of this Agreement shall lapse on the Vesting Date or Dates specified in the
following schedule so long as the Grantee remains an employee of the Company or
one of its Subsidiaries on such Vesting Date or Dates. If a series of Vesting
Dates is specified, then the restrictions and conditions in Paragraph 2 shall
lapse only with respect to the percentage of LTIP Units accepted by the Grantee
hereunder that is specified as vested on such date.

<Table>

                 Vested
                 ------
                                        
                   50%                     __________, 200_

                   50%                     __________, 200_
</Table>

     Subsequent to such Vesting Date or Dates, the LTIP Units on which all
restrictions and conditions have lapsed shall no longer be deemed restricted.

     4.   ACCELERATION OF VESTING IN SPECIAL CIRCUMSTANCES. If (i) the Grantee
ceases to be a Director of the Company by reason of death, incapacity due to
physical or mental illness or disability or (ii) a Change of Control (as defined
in Section 16 of the Plan) occurs, any restrictions and conditions on all LTIP
Units subject to this Award shall be deemed waived by the Administrator and all
LTIP Units granted hereby shall automatically become fully vested.

                                        2

     Anything to the contrary in the Plan notwithstanding, in the event a
Transaction (as defined in Section 3(c) of the Plan) occurs, the Board (as
defined in the Plan), or the board of directors of any corporation assuming the
obligations of the Company ("ACQUIROR") shall have the right to take the action
specified in Section 3(c) of the Plan ("MERGER-RELATED ACTION") subject to the
following limitations and qualifications:

          (a)  if (i) all LTIP Units awarded to the Grantee hereunder are
eligible, as of the time of the Merger-Related Action (and giving effect to the
anticipated consummation of the Transaction as provided in Section 8.8 of the
Partnership Agreement), for conversion into Common Units (as defined in the
Partnership Agreement) and (ii) the Grantee is afforded the opportunity to
effect such conversion and receive, in consideration for the Common Units into
which his or her LTIP Units shall have been converted, the same kind and amount
of consideration as other holders of Common Units in connection with the
Transaction, then Merger-Related Action of the kind specified in either clause
(i) or clause (ii) of Section 3(c) of the Plan shall be permitted and available
to the Company and the Acquiror;

          (b)  if (i) some or all of the LTIP Units awarded to the Grantee
hereunder are not, as of the time of the Merger-Related Action, so eligible for
conversion into Common Units, and (ii) the acquiring or succeeding entity is
itself, or has a subsidiary which is organized as a partnership or limited
liability company (consisting of a so called "UPREIT" or other structure similar
in purpose or effect to that of the Company and the Partnership), then
Merger-Related Action of the kind specified in clause (i) of Section 3(c) of the
Plan must be taken by the Acquiror with respect to all LTIP Units which are not
so convertible at the time, whereby (A) all such LTIP Units covered by this
Award shall be assumed by the acquiring or succeeding entity, or equivalent
awards shall be substituted by the acquiring or succeeding entity, and (B) the
acquiring or succeeding entity shall preserve with respect to the assumed LTIP
Units or any securities to be substituted for such LTIP Units, 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; and

          (c)  if (i) some or all of the LTIP Units awarded to the Grantee
hereunder are not, as of the time of the Merger-Related Action, so eligible for
conversion into Common Units, and (ii) the conditions set forth in Section 4(b)
above cannot be satisfied after exercise of reasonable commercial efforts by the
Company and/or Acquiror, then Merger-Related Action of the kind specified in
clause (ii) of Section 3(c) of the Plan must be taken by the Company or the
Acquiror, in which case such action shall be based on the principle that the
settlement of the terminated award of LTIP Units which are not convertible into
Common Units requires a payment of the same kind and amount of consideration
payable in connection with the Transaction to a holder of the number of Common
Units into which the LTIP Units to be terminated could be converted (including
the right to make elections as to the type of consideration) if the Transaction
were of a nature that permitted a revaluation of the Grantee's capital account
balance under the terms of the Partnership Agreement, as determined by the
Administrator in good faith in accordance with the Plan.

     5.   DISTRIBUTIONS.  Distributions on the LTIP Units shall be paid
currently to the Grantee in accordance with the terms of the Partnership
Agreement. The right to distributions set forth in this Section 5 shall be
deemed a Dividend Equivalent Right for purposes of the Plan.

                                        3
<Page>

     6.   INCORPORATION OF PLAN. Notwithstanding anything herein to the
contrary, this Agreement shall be subject to and governed by all the terms and
conditions of the Plan. Capitalized terms used in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein.

     7.   COVENANTS, REPRESENTATION AND WARRANTIES. The Grantee hereby makes
the covenants, representations and warranties and set forth on ANNEX B 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 B were false when made or have,
as a result of changes in circumstances, become false.

     8.   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.

     9.   AMENDMENT. The Grantee acknowledges that the Plan may be amended or
discontinued in accordance with Section 14 thereof and that this Agreement may
be amended or canceled by the Administrator, on behalf of 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. The provisions of Section
4 of this Agreement applicable to the termination of the LTIP Units covered by
this Award in connection with a Transaction (as defined in the Plan) pursuant to
Section 3(b) of the Plan shall apply, MUTATIS MUTANDI to amendments,
discontinuance or cancellation pursuant to this Section 9 or Section 14 of the
Plan.

     10.  NO OBLIGATION TO CONTINUE AS DIRECTOR.  This Award does not confer
upon the Grantee any right to continue as a Director.

     11.  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.

     12.  GOVERNING LAW.  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware, applied without regard to
conflict of law principles.

                 with his or her spouse) in excess of $1 million.

     / /  (ii)   The Grantee is an individual with income (without including any

                 or the Company, the general partner of the Partnership. As used
                 herein, "executive officer" shall mean the president, any vice
                 president in charge of a principal business unit, division or
                 function (such as sales, administration or finance), any other
                 officer who performs a policy-making function, or any other
                 person who performs similar policy-making functions for the
                 Partnership or the Company.

     (b)  The Grantee has received and had an opportunity to review the
following documents (the "BACKGROUND DOCUMENTS"):

          (i)    The Company's latest Annual Report to Stockholders;

          (ii)   The Company's Proxy Statement for its most recent Annual
                 Meeting of Stockholders;

          (iii)  The Company's Report on Form 10-K for the fiscal year most

                 one has been filed by the Company with the Securities and
                 Exchange Commission since the filing of the report described in
                 clause (iii) above;

          (v)    Each of the Company's Current Report(s) on Form 8-K, if any,
                 filed since the end of the fiscal year most recently ended;

                                       B-1
<Page>

          (vi)   The Partnership Agreement;

          (vii)  The Plan; and

          (viii) The Company's Amended and Restated Certificate of
                 Incorporation.

     The Grantee also acknowledges that any delivery of the Background Documents
and other information relating to the Company and the Partnership prior to the
determination by the Partnership of the suitability of the Grantee as an LTIP
Unitholder shall not constitute an offer of LTIP Units until such determination
of suitability shall be made.

     (c)  The Grantee hereby represents and warrants that

          (i)    The Grantee either (i) is an "accredited investor" as defined
     in Rule 501(a) under the Securities Act of 1933, as amended (the
     "Securities Act"), or (ii) by reason of his or her business and financial
     experience, together with the business and financial experience of those
     persons, if any, retained by the Grantee to represent or advise him or her
     with respect to the grant to him or her of LTIP Units, the potential
     conversion of LTIP Units into Common Units of the Partnership ("COMMON
     UNITS") and the potential redemption of such Common Units for shares of
     common stock of the Company ("REIT SHARES"), has such knowledge,
     sophistication and experience in financial and business matters and in
     making investment decisions of this type that he or she (A) is capable of
     evaluating the merits and risks of an investment in the Partnership and
     potential investment in the Company and of making an informed investment
     decision, (B) is capable of protecting his or her own interest or has
     engaged representatives or advisors to assist him or her in protecting his
     or her interests, and (C) is capable of bearing the economic risk of such
     investment.

          (ii)   The Grantee understands that (A) the award of LTIP Units under
     the Plan involves risks different from, and in certain circumstances
     substantially greater than those involved in an award of a comparable
     number of REIT Shares as a "Restricted Stock Award" under the Plan; (B) the
     Grantee is responsible for consulting his or her own tax advisors with
     respect to the application of the U.S. federal income tax laws, and the tax
     laws of any state, local or other taxing jurisdiction to which the Grantee
     is or by reason of the award of LTIP Units may become subject, to his or
     her particular situation; (C) the Grantee has not received or relied upon
     business or tax advice from the Company, the Partnership or any of their
     respective employees, agents, consultants or advisors; (D) the Grantee
     provides services to the Partnership on a regular basis and in such
     capacity has access to such information, and has such experience of and
     involvement in the business and operations of the Partnership, as the
     Grantee believes to be necessary and appropriate to make an informed
     decision to accept this Award of LTIP Units; and (E) an investment in the
     Partnership and/or the Company involves substantial risks. The Grantee has
     been given the opportunity to make a thorough investigation of matters
     relevant to the LTIP Units and has been furnished with, and has reviewed
     and understands, materials relating to the Partnership and the Company and
     their respective activities (including, but not limited to, the Background
     Documents). The Grantee has been afforded the opportunity to obtain

                                       B-2
<Page>

     any additional information (including any exhibits to the Background
     Documents) deemed necessary by the Grantee to verify the accuracy of
     information conveyed to the Grantee. The Grantee confirms that all
     documents, records, and books pertaining to his or her receipt of LTIP
     Units which were requested by the Grantee have been made available or
     delivered to the Grantee. The Grantee has had an opportunity to ask
     questions of and receive answers from the Partnership and the Company, or
     from a person or persons acting on their behalf, concerning the terms and
     conditions of the LTIP Units. THE GRANTEE HAS RELIED UPON, AND IS MAKING
     ITS DECISION SOLELY UPON, THE BACKGROUND DOCUMENTS AND OTHER WRITTEN
     INFORMATION PROVIDED TO THE GRANTEE BY THE PARTNERSHIP OR THE COMPANY. The
     Grantee did not receive any tax, legal or financial advice from the
     Partnership or the Company and, to the extent it deemed necessary, has
     consulted with its own advisors in connection with its evaluation of the
     Background Documents and this Agreement and the Grantee's receipt of LTIP
     Units.

          (iii)  The LTIP Units to be issued, the Common Units issuable upon
     conversion of the LTIP Units and any REIT Shares issued in connection with
     the redemption of any such Common Units will be acquired for the account of
     the Grantee for investment only and not with a current view to, or with any
     intention of, a distribution or resale thereof, in whole or in part, or the
     grant of any participation therein, without prejudice, however, to the
     Grantee's right (subject to the terms of the LTIP Units, the Plan and this
     Agreement) at all times to sell or otherwise dispose of all or any part of
     his or her LTIP Units, Common Units or REIT Shares in compliance with the
     Securities Act, and applicable state securities laws, and subject,
     nevertheless, to the disposition of his or her assets being at all times
     within his or her control.

          (iv)   The Grantee acknowledges that (A) neither the LTIP Units to be
     issued, nor the Common Units issuable upon conversion of the LTIP Units,
     have been registered under the Securities Act or state securities laws by
     reason of a specific exemption or exemptions from registration under the
     Securities Act and applicable state securities laws and, if such LTIP Units
     or Common Units are represented by certificates, such certificates will
     bear a legend to such effect, (B) the reliance by the Partnership and the
     Company on such exemptions is predicated in part on the accuracy and
     completeness of the representations and warranties of the Grantee contained
     herein, (C) such LTIP Units, or Common Units, therefore, cannot be resold
     unless registered under the Securities Act and applicable state securities
     laws, or unless an exemption from registration is available, (D) there is
     no public market for such LTIP Units and Common Units and (E) neither the
     Partnership nor the Company has any obligation or intention to register
     such LTIP Units or the Common Units issuable upon conversion of the LTIP
     Units under the Securities Act or any state securities laws or to take any
     action that would make available any exemption from the registration
     requirements of such laws, except, that, upon the redemption of the Common
     Units for REIT Shares, the Company currently intends to issue such REIT
     Shares under the Plan and pursuant to a Registration Statement on Form S-8
     under the Securities Act, to the extent that the Grantee is eligible to
     receive such REIT Shares under the Plan at the time of such issuance, the
     Company has filed a Form S-8 Registration Statement with the Securities and
     Exchange Commission registering the issuance of such REIT Shares and such

     agent, or affiliate of any of them, and the Grantee has received no
     information relating to an investment in the Partnership or the LTIP Units
     except the information specified in Paragraph (b) above.

     (e)  So long as the Grantee holds any LTIP Units, the Grantee shall
disclose to the Partnership in writing such information as may be reasonably
requested with respect to ownership of LTIP Units as the Partnership may deem
reasonably necessary to ascertain and to establish compliance with provisions of
the Internal Revenue Code of 1986, as amended (the "CODE"), applicable to the
Partnership or to comply with requirements of any other appropriate taxing
authority.
