                                     ARTICLE III

                    3.1  REDEMPTION RIGHTS.  The Investor, upon admission as 
a limited partner of the Partnership, will be granted rights to redeem OP 
Units on the terms and conditions set forth in the Partnership Agreement,

Agreement, the Investor may not: (i) exercise such rights with respect to all 
or any portion of the OP Units prior to that date which is six months prior 
to the Closing, (ii) deliver more than two separate redemption notices per 
calendar year, and (iii) redeem less than 5,000 OP Units (or, if the Investor 
holds less than 5,000 OP Units, all of the OP Units held by the Investor) in 
a single redemption.

                    3.2  NOTICE AND REGISTRATION.  If the Company proposes to 
register any shares of Common Stock or other securities issued by it having 
terms substantially similar to Eligible Securities ("Other Securities") for 
public sale under the Securities Act (whether proposed to be offered for sale 
by the Company or by any other Person) on a form and in a manner which would 
permit registration of Eligible Securities for sale to the public under the 
Securities Act, it will give prompt written notice to each Investor of its 
intention to do so, and upon the written request of any of the Investors 
delivered to the Company within fifteen (15) Business Days after the giving 
of any such notice (which request shall specify the number of Eligible 
Securities intended to be disposed of by such Investor and the intended 
method of disposition thereof) the Company will use all reasonable efforts to 
effect, in connection with the registration of the Other Securities, the 
registration under the Securities Act of all Eligible Securities which the 
Company has been so requested to register by the Investor or Investors, to 
the extent required to permit the disposition (in accordance with the 
intended method or methods thereof as aforesaid) of Eligible Securities so to 
be registered provided that:

                    (a)  if, at any time after giving such written notice of its
                    intention to register any Other Securities and prior to the
                    effective date of the registration statement filed in
                    connection with such registration, the Company shall
                    determine for any reason not to register the Other
                    Securities, the Company may, at its election, give


                                          3


                    written notice of such determination to the Investor or
                    Investors seeking registration hereunder (hereafter referred
                    to as the "SELLING INVESTORS") and thereupon the Company 
                    shall be relieved of its obligation to register such
                    Eligible Securities in connection with the registration of
                    such Other Securities (but not from its obligation to
                    pay Registration Expenses to the extent incurred in
                    connection therewith as provided in Section 3.2);

                    (b)  The Company will not be required to effect any
                    registration pursuant to this Article 3 if the Company shall
                    have been advised in writing (with a copy to Investor) by a
                    nationally recognized independent investment banking firm
                    selected by the Company to act as lead underwriter in
                    connection with the public offering of securities by the
                    Company, that in such firm's opinion, a registration of the
                    Eligible Securities which the Company has been requested to
                    register by Investor at that time would materially and
                    adversely affect the Company's own scheduled offering; and

                    (c)  The Company shall not be required to effect any
                    registration of Eligible Securities under this Article 3
                    incidental to the registration of any of its securities in
                    connection with mergers, acquisitions, exchange offers,
                    subscription offers, dividend reinvestment plans or stock
                    options or other employee benefit plans.

                    3.3  REGISTRATION EXPENSES.  The Company (as between the 
Company and the Selling Investors) shall be responsible for the payment of 
all Registration Expenses in connection with any registration pursuant to 
this Article 3.

                    3.4  LOCK-UP AGREEMENT.  The Investor agrees, that, prior 
to that date which is one year following the Closing Date, it will not 
directly or indirectly, offer, sell, contract to sell, grant any option to 
purchase, make any short sale, transfer, pledge, cause a registration of, or 
otherwise dispose of or make a distribution of any of the shares of Common 
Stock acquired by the redemption of all or any portion of its OP Units, 
without the prior written consent of the Company.

                                      ARTICLE IV

                               REGISTRATION PROCEDURES

                    4.1  REGISTRATION AND QUALIFICATION.  If and whenever the 
Company is required to use all reasonable efforts to effect the registration 
of any Eligible Securities under the Securities Act as provided in Article 3, 
the Company will as promptly as is practicable:

                    (a)  prepare, file and use all reasonable efforts to cause
                    to become effective a registration statement under the
                    Securities Act regarding the Eligible Securities to be
                    offered;

                    (b)  prepare and file with the SEC such amendments and
                    supplements to such registration statement and the
                    prospectus used in connection therewith as may be necessary
                    to keep such registration statement effective and to comply
                    with the


                                          4


        provisions of the Securities Act with respect to the
        disposition of all Eligible Securities until the earlier of
        such time as all of such Eligible Securities have been
        disposed of in accordance with the intended methods of
        disposition by the Selling Investors set forth in
        such registration statement or the expiration of twelve (12)
        months after such registration statement becomes effective;

        (c)  furnish to each Selling Investor and to any underwriter
        of such Eligible Securities such number of conformed copies
        of such registration statement and of each such amendment and supplement
        thereto (in each case including all exhibits), such number of copies
        of the prospectus included in such registration statement (including
        each preliminary prospectus and any summary prospectus), in conformity
        with the requirements of the Securities Act, such documents
        incorporated by reference in such registration statement or
        prospectus, and such other documents as such Selling Investor or such
        underwriter may reasonably request;

        (d)  use all reasonable efforts to register or qualify all Eligible
        Securities covered by such registration statement under such other
        securities or blue sky laws of such jurisdictions as the Selling
        Investors or any underwriter of such Eligible Securities shall
        reasonably request, and do any and all other acts and things which may
        be reasonably requested by the Selling Investors or any underwriter to
        consummate the disposition in such jurisdictions of the Eligible
        Securities covered by such registration statement, except the Company
        shall not for any such purpose be required to qualify generally to do
        business as a foreign corporation in any jurisdiction wherein it is
        not so qualified, or to subject itself to taxation in any jurisdiction
        where it is not then subject to taxation, or to consent to general
        service of process in any jurisdiction where it is not then subject to
        service of process;

        (e)  use all reasonable efforts to list the Eligible Securities on
        each national securities exchange on which the Common Stock is then
        listed, if the listing of such securities is then permitted under the
        rules of such exchange; and 

        (f)  immediately notify the Selling Investors at any time when a
        prospectus relating to a registration pursuant to Article 3 hereof is
        required to be delivered under the Securities Act of the happening of
        any event as a result of which the prospectus included in such
        registration statement, as then in effect, includes an untrue
        statement of material fact or omits to state any material fact
        required to be stated therein or necessary to make the statements
        therein, in the light of the circumstances under which they were made,
        not misleading, and at the request of any Selling Investor prepare and
        furnish to such Investor as many copies of a supplement to or an
        amendment of such prospectus as the Selling Investor may request so
        that, as thereafter delivered to the purchasers of such Eligible
        Securities, such prospectus shall not include an untrue statement of a
        material fact or omit to state a material fact required to be stated
        therein or necessary to make the statements therein, in light of the
        circumstances under which they were made, not misleading.


                                          5


The Company may require the Investors to furnish the Company such information 
regarding the Investors and the distribution of such securities as the 
Company may from time to time reasonably request in writing and as shall be 
required by law or by the SEC in connection with any registration.  The 
Company may also impose such restrictions and limitations on the distribution 
of such Eligible Securities as the Company reasonably believes are necessary 
or advisable to comply with applicable law or to effect an orderly 
distribution, including those restrictions set forth in Section 4.3 hereof.

                    4.2  UNDERWRITING.  (a) In the event that any 
registration pursuant to Article 3 hereof shall involve, in whole or in part, 
an underwritten offering, the Company may require Eligible Securities 
requested to be registered pursuant to Article 3 to be included in such 
underwriting on the same terms and conditions as shall be applicable to the 
Other Securities being sold through underwriters under such registration.

                    (b)  If requested by the underwriters for any 
underwritten offering of Eligible Securities pursuant to a registration 
requested hereunder, the Company will enter into and perform its obligations 
under an underwriting agreement with such underwriters for such offering, 
such agreement to contain such representations and warranties by the Company 
and such other terms and provisions as are customarily contained in 
underwriting agreements with respect to secondary distributions, including, 
without limitation, indemnities and contribution to the effect and to the 
extent provided in Article 6 hereof.  Each Selling Investor shall be a party 
to any such underwriting agreement and the representations and warranties by, 
and the other agreements on the part of, the Company to and for the benefit 
of such underwriters shall also be made to and for the benefit of each such 
Selling Investor.  Such agreement shall also contain such representations and 
warranties by each such Selling Investor and such other terms and provisions 
as are customarily contained in underwriting agreements with respect to 
secondary distributions, including, without limitation, indemnities and 
contribution to the effect and to the extent provided in Article 6.

                    4.3  BLACKOUT PERIODS.  At any time when a registration 
statement effected pursuant to Article 3 relating to Eligible Securities is 
effective, upon written notice from the Company to an Investor that the 
Company has determined in good faith, with the advice of counsel, that such 
Investor's sale of Eligible Securities pursuant to the registration statement 
would require disclosure of non-public material information the disclosure of 
which would have a material adverse effect on the Company or would otherwise 
adversely effect a material financing, acquisition, disposition, merger or 
other comparable transaction (a "Blackout"), such Investor shall suspend 
sales of Eligible Securities pursuant to such registration statement until 
the earlier of:

                         (a)  the date upon which such material information 
is disclosed to the public or ceases to be material, or

                         (b)  such time as the Company notifies such Investor 
that sales pursuant to such registration statement may be resumed.

                    4.4  QUALIFICATION FOR RULE 144 SALES.  The Company will 
take all actions reasonably necessary to comply with the filing requirements 
described in Rule 144(c)(1) so as to


                                          6


enable the Investors to sell Eligible Securities without registration under 
the Securities Act and, upon the written request of any Investor, the Company 
will deliver to such Investor a written statement as to whether it has 
complied with such filing requirements.

                                      ARTICLE V

                        PREPARATION; REASONABLE INVESTIGATION

                    5.1  PREPARATION; REASONABLE INVESTIGATION.  In 
connection with the preparation and filing of each registration statement 
registering Eligible Securities under the Securities Act, the Company will 
give each Selling Investor and the underwriters, if any, and their respective 
counsel and accountants, drafts of such registration statement for their 
review and comment prior to filing and such reasonable and customary access 
to its books and records and such opportunities to discuss the business of 
the Company with its officers and the independent public accountants who have 
certified its financial statements as shall be necessary, in the opinion of 
the Selling Investors and such underwriters or their respective counsel, to 
conduct a reasonable investigation within the meaning of the Securities Act.

                                      ARTICLE VI

                           INDEMNIFICATION AND CONTRIBUTION

                    6.1  INDEMNIFICATION AND CONTRIBUTION.  (a)  In the event 
of any registration of Eligible Securities hereunder, the Company will enter 
into customary indemnification arrangements to indemnify and hold harmless 
each Selling Investor, and each Person who participates as an underwriter in 
the offering or sale of such securities, and each Person, if any, who 
controls such underwriter within the meaning of the Securities Act against 
any losses, claims, damages, liabilities and expenses, joint or several, to 
which such Person may be subject under the Securities Act or otherwise 
insofar as such losses, claims, damages, liabilities or expenses (or actions 
or proceedings in respect thereof) arise out of or are based upon (i) any 
untrue statement or alleged untrue statement of any material fact contained 
in any registration statement under which such securities were registered 
under the Securities Act, any preliminary prospectus or final prospectus 
included therein, or any amendment or supplement thereto, or any document 
incorporated by reference therein, or (ii) any omission or alleged omission 
to state therein a material fact required to be stated therein or necessary 
to make the statements therein not misleading, and the Company will promptly 
reimburse each such Person for any legal or any other expenses reasonably 
incurred by such Person in connection with investigating or defending any 
such loss, claim, damage, liability, action or proceeding; PROVIDED that the 
Company shall not be liable in any such case to the extent that any such 
loss, claim, damage, liability (or action or proceeding in respect thereof) 
or expense arises out of or is based upon an untrue statement or alleged 
untrue statement or omission or alleged omission made in such registration 
statement, any such preliminary prospectus or final prospectus, amendment or 
supplement in reliance upon and in conformity with written information 
furnished to the Company by such Selling Investor expressly for use in the 
registration statement.  Such indemnity shall remain in full force and effect 
regardless of any investigation made by or on behalf of such Selling Investor 
or any such


                                          7


Person and shall survive the transfer of such securities by such Selling 
Investor.  The Company also shall agree to provide provision for contribution 
as shall be reasonably requested by the Selling Investors or any underwriters 
in circumstances where such indemnity is held unenforceable.

                    (b)  Each Selling Investor, by virtue of exercising its 
registration rights hereunder, agrees and undertakes to enter into customary 
indemnification arrangements to indemnify and hold harmless (in the same 
manner and to the same extent as set forth in clause (a) of this Article 6) 
the Company, each director of the Company, each officer of the Company who 
shall sign such registration statement, each Person who participates as an 
underwriter in the offering or sale of such securities and each Person, if 
any, who controls the Company or any such underwriter within the meaning of 
the Securities Act, with respect to any statement in or omission from such 
registration statement, any preliminary prospectus or final prospectus 
included therein, or any amendment or supplement thereto, but only to the 
extent that such statement or omission was made in reliance upon and in 
conformity with written information furnished by such Investor to the Company 
expressly for use in the registration statement.  Such indemnity shall remain 
in full force and effect regardless of any investigation made by or on behalf 
of the Company or any such director, officer or controlling Person and shall 
survive the transfer of the registered securities by the Investor and the 
expiration of this Agreement.  Each Investor also shall agree to provide 
provision for contribution as shall be reasonably requested by the Company or 
any underwriters in circumstances where such indemnity is held unenforceable.

                    (c)  Indemnification and contribution similar to that 
specified in the preceding subdivisions of this Article 6 (with appropriate 
modifications) shall be given by the Company and each Selling Investor with 
respect to any required registration or other qualification of Eligible 
Securities under any federal or state law or regulation of governmental 
authority other than the Securities Act.

                                     ARTICLE VII

                           TRANSFER OF REGISTRATION RIGHTS

                    7.1  TRANSFER OF REGISTRATION RIGHTS.  The Investors may 
NOT transfer the registration rights granted hereunder to any other Person.
