         prior written consent of the General Partner or the Company, as the
         case may be, which may be withheld in their sole and absolute
         discretion;

                  (iii) a Holder may Dispose of Units or Shares upon the death
         of a Holder to such Holder's estate, executor, administrator or
         personal representative or to such Holder's heirs or beneficiaries

         such Holder shall have (A) first obtained the written agreement of the
         pledgee to exercise its redemption rights with respect to any pledged
         Units pursuant to Section 3.2.C of the Partnership Agreement
         immediately upon taking any action with respect to such Units and (B)

         and

                  (vi) a Holder may Dispose of Units or Shares to a Charitable
         Organization;

Agreement, this Section 1(c) shall control.

         (d) BINDING OBLIGATION; CERTAIN PROVISIONS OF ORGANIZATIONAL DOCUMENTS.
If a Holder Disposes of Units or Shares under any provision of this Section 2,
such Units or Shares shall remain subject to this Agreement and, as a condition
of the validity of such Disposition, the transferee shall be required to execute
and deliver a counterpart of this Agreement. Thereafter, such transferee shall
be deemed to be the Holder for purposes of this Agreement. The provisions set
forth in this Agreement permitting Dispositions of the Shares or Units shall not
be deemed in any manner to limit any provision of the Company's Articles of
Amendment and Restatement or the Partnership Agreement which sets forth other
restrictions or limitations on the transferability of Shares or Units.

         (e) Any attempted Disposition in violation of the terms of this
Agreement shall be ineffective to vest in any purported transferee any right,
title, or interest in or to the Units or the Shares purported to be Disposed of,
and the Company shall not recognize any such purported transferee as the holder
or owner of such Units or Shares for any purpose, including without limitation
for purposes of exercising voting rights or rights to receive dividends or other
distributions in respect of such Units or Shares.

         (f) The restrictions on Dispositions contained in this Section 2 shall
terminate, with respect to Shares only, on the effective date of the
Registration Statement; PROVIDED, HOWEVER, that the foregoing shall not be
deemed in any manner to limit any provision of the Company's Articles of
Amendment and Restatement which sets forth other restrictions on the
transferability of Shares or Units.

         4. [Intentionally Omitted].

         5. REGISTRATION.

         (a) FILING OF SHELF REGISTRATION STATEMENT. Subject to the conditions
set forth in this Agreement, the Company shall cause to be filed by April 29,
2003, a registration statement under Rule 415 under the Securities Act relating
to (i) the issuance to all Holders of Registrable Shares upon the redemption of
Units or in exchange for Units, and (ii) the sale by any Holder, including a
Holder who is an affiliate of the Company (as defined in Rule 144(a) under the
Securities Act), of all of the Registrable Shares of such Holder or Holders in
accordance with the terms hereof (the "REGISTRATION STATEMENT"), and shall use
reasonable efforts to cause such Registration Statement to be declared effective
by the SEC as of the sixtieth (60th) day following the filing of the
Registration Statement with the SEC. The Company agrees to use reasonable
efforts to keep the Registration Statement, after its date of effectiveness,
continuously effective with respect to the Registrable Shares of all Holders
until the earlier of (a) the date on which the Holders no longer hold any
Registrable Shares or (b) the date on which all of the Registrable Shares held
by all Holders have become eligible for sale pursuant to Rule 144(k) (or any
successor provision) (hereinafter referred to as the "SHELF REGISTRATION
EXPIRATION DATE").

         (b) The Company shall only be required to file one Registration
Statement.

         (c) NOTIFICATION AND DISTRIBUTION OF MATERIALS. The Company shall
notify each Holder of the effectiveness of the Registration Statement and shall
furnish to such Holder (at the Company's cost) such number of copies of the
Registration Statement (including any amendments, supplements and exhibits), the
Prospectus contained therein (including each preliminary prospectus and all
related amendments and supplements) and any documents incorporated by reference
in the Registration Statement and such other documents as such Holder may
reasonably request in order to facilitate its sale of the Registrable Shares in
the manner described in the Registration Statement.

         (d) AMENDMENTS AND SUPPLEMENTS. The Company shall prepare and file with
the SEC from time to time such amendments and supplements to the Registration
Statement and Prospectus used in connection therewith as may be necessary to
keep the Registration Statement effective and to comply with the provisions of
the Securities Act with respect to the disposition of all the Registrable Shares
until the earlier of (a) such time as all of the Registrable Shares have been
disposed of in accordance with the intended methods of disposition by all
Holders or issued in accordance with the intended method of issuance by the
Company or (b) the date on which the Registration Statement ceases to be
effective in accordance with the terms of this SECTION 5. Upon ten (10) business
days' notice, the Company shall file any supplement or post-effective amendment
to the Registration Statement with respect to the plan of distribution or a
Holder's ownership interests in its Registrable Shares that is reasonably
necessary to permit the sale of such Holder's Registrable Shares pursuant to the
Registration Statement. The Company shall file any necessary listing
applications or amendments to the existing applications to cause the Shares
registered under any Registration Statement to be then listed or quoted on the
primary exchange or quotation system on which the Common Shares are then listed
or quoted.

         (e) In event that the Registrable Shares being registered by the
Company pursuant to the Registration Statement are to be sold by the Holders in
an underwritten public

<PAGE>


                                      -7-


offering, the Company shall use its reasonable efforts to enter into such
customary agreements (including underwriting agreements in customary form), to
provide such customary opinions of counsel and "comfort" letters and take all
such other actions as the underwriters of such offering reasonably request in
order to expedite or facilitate the disposition of such Registrable Securities.

         (f) NOTICE OF CERTAIN EVENTS. The Company shall promptly notify each
Holder of, and confirm in writing, the filing of the Registration Statement or
any Prospectus, amendment or supplement related thereto or any post-effective
amendment to the Registration Statement and the effectiveness of any
post-effective amendment.

         At any time when a Prospectus relating to the Registration Statement is
required to be delivered under the Securities Act by a Holder to a transferee,
the Company shall immediately notify each Holder 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 a material fact or omits to
state any 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. In such event, the Company shall promptly prepare and furnish to
each applicable Holder a reasonable number of copies of a supplement to or an
amendment of such Prospectus as may be necessary so that, as thereafter
delivered to the purchasers of Registrable Shares, sold under the Prospectus,
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 are made, not
misleading. The Company will, if necessary, promptly amend the Registration
Statement of which such Prospectus is a part to reflect such amendment or
supplement.

         6. STATE SECURITIES LAWS. Subject to the conditions set forth in this
Agreement, the Company shall, in connection with the filing of the Registration
Statement hereunder, file such documents as may be necessary to register or
qualify the Registrable Shares under the securities or "Blue Sky" laws of such
states as any Holder may reasonably request, and the Company shall use its
reasonable efforts to cause such filings to become effective in a timely manner;
PROVIDED, HOWEVER, that the Company shall not be obligated to qualify as a
foreign corporation to do business under the laws of any such state in which it
is not then qualified or to file any general consent to service of process in
any such state. Once effective, the Company shall use its reasonable efforts to
keep such filings effective until the earlier of (a) such time as all of the
Registrable Shares have been disposed of in accordance with the intended methods
of disposition by the Holders as set forth in the Registration Statement, (b) in
the case of a particular state, a Holder has notified the Company that it no
longer requires an effective filing in such state in accordance with its
original request for filing or (c) the date on which the Registration Statement
ceases to be effective.

         7. EXPENSES. The Company shall bear all Registration Expenses incurred
in connection with the registration of the Registrable Shares pursuant to this
Agreement, except that each Holder shall be responsible for any brokerage or
underwriting commissions and taxes of any kind (including, without limitation,
transfer taxes) with respect to any disposition, sale or transfer of Registrable
Shares sold by it and for any legal, accounting and other expenses incurred by
it.

         8. INDEMNIFICATION BY THE COMPANY. The Company agrees to indemnify and
hold harmless each of the Holders and their respective officers, directors,
employees, agents, representatives and affiliates, and each Person, if any, that
controls a Holder within the meaning of the Securities Act, and each other
Person, if any, subject to liability because of his, her or its

<PAGE>


                                      -8-


connection with a Holder (each, an "INDEMNITEE"), against any and all losses,
claims, damages, actions, liabilities, costs and expenses (including, without
limitation, reasonable fees, expenses and disbursements of attorneys and other
professionals), joint or several, arising out of or based upon any violation by
the Company of any rule or regulation promulgated under the Securities Act
applicable to the Company and relating to action or inaction required of the
Company in connection with the Registration Statement or Prospectus, or upon any
untrue or alleged untrue statement of material fact contained in the
Registration Statement or any Prospectus, or any omission or alleged omission to
state therein 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; PROVIDED, THAT the Company shall not be liable to such
Indemnitee or any Person who participates as an underwriter in the offering or
sale of Registrable Shares or any other Person, if any, who controls such
underwriter within the meaning of the Securities Act, 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 (a) an untrue
statement or alleged untrue statement or omission or alleged omission made in
such Registration Statement or in any such Prospectus in reliance upon and in
conformity with information regarding such Indemnitee or its plan of
distribution or ownership interests which was furnished in writing to the
Company for use in connection with the Registration Statement or the Prospectus
contained therein by such Indemnitee, or (ii) a Holder's failure to send or give
a copy of the final, amended or supplemented prospectus furnished to such Holder
by the Company at or prior to the time such action is required by the Securities
Act to the selling broker for delivery to the Person claiming an untrue
statement or alleged untrue statement or omission or alleged omission if such
statement or omission was corrected in such final amended or supplemented
prospectus.

         9. COVENANTS OF THE HOLDER. Each of the Holders (severally and not
jointly) hereby agrees (a) to cooperate with the Company and to furnish to the
Company all such information concerning its plan of distribution and ownership
interests with respect to its Registrable Shares and such other information as
the Company may reasonably request in connection with the preparation of the
Registration Statement and any filings with any state securities commissions as
the Company may reasonably request, (b) to deliver to the selling broker or to
otherwise cause delivery of the Prospectus contained in such Registration
Statement to any purchaser of the shares covered by the Registration Statement
from such Holder, (c) to sell such Holder's Registrable Shares only in the
manner set forth in the Registration Statement, (d) to comply with the
anti-manipulation rules under the Exchange Act in connection with purchases and
sales of securities of the Company during the time the Registration Statement
remains effective, (e) to suspend sales during the periods when sales are to be
suspended pursuant to Section 10, (f) to furnish to the Company in writing such

representing the Registrable Shares, provided that such stop transfer orders are
consistent with the other provisions of this Agreement, and (h) to indemnify the
Company, its officers, directors, employees, agents, representatives and
Affiliates, and each Person, if any, who controls the Company within the meaning
of the Securities Act, and each other Person, if any, subject to liability
because of his connection with the Company, against any and all losses, claims,
damages, actions, liabilities, costs and expenses arising out of or based upon
(i) any untrue statement or alleged untrue statement of material fact contained
in either the Registration Statement or the Prospectus contained therein, or any
omission or alleged omission to state therein 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, if and to the extent
that such statement or omission occurs from reliance upon and in conformity with
written

<PAGE>


                                      -9-


information regarding such Holder, its plan of distribution or its ownership
interests, which was furnished to the Company by such Holder for use therein
unless such statement or omission was corrected in writing to the Company not
less than three (3) business days prior to the date of the final prospectus (as
supplemented or amended, as the case may be), or (ii) the failure by such Holder
to deliver to the selling broker or to otherwise cause to be delivered the
Prospectus contained in such Registration Statement (as amended or supplemented,
if applicable) furnished by the Company to such Holder to any purchaser of the
shares covered by such Registration Statement from such Holder through no fault
of the Company.

         10.      SUSPENSION OF REGISTRATION REQUIREMENT; RESTRICTION ON SALES.

         (a) The Company shall promptly notify each Holder of, and confirm in
writing, the issuance by the SEC of any stop order suspending the effectiveness
of the Registration Statement or the initiation of any proceedings for that
purpose. The Company shall use its reasonable efforts to obtain the withdrawal
of any order suspending the effectiveness of the Registration Statement at the
earliest possible moment.

         (b) Notwithstanding anything to the contrary set forth in this
Agreement, the Company's obligation under this Agreement to cause the
Registration Statement and any filings with any state securities commission to
become effective or to amend or supplement the Registration Statement shall be
suspended in the event and during such period as unforeseen circumstances exist
(including without limitation (i) an underwritten primary offering by the
Company, if the Company is advised in writing by the underwriters that the sale
of Registrable Shares under the Registration Statement would impair the pricing
or commercial practicality of the primary offering, or (ii) the existence of
material, nonpublic information relating to the Company which, in the reasonable
opinion of the Company, would not be appropriate for disclosure during that time
(such unforeseen circumstances being hereinafter referred to as a "SUSPENSION
EVENT") that would make it impractical or inadvisable to cause the Registration
Statement or such filings to become effective or to amend or supplement the
Registration Statement, but such suspension shall continue only for so long as
such event or its effect is continuing; provided, however, that in no event
shall such period of suspension last for longer than one-hundred twenty (120)
days from its inception. The Company shall notify each Holder of the existence
and, in the case of circumstances referred to in clause (i) of this Section
10(b), nature of any Suspension Event.

         11. BLACK-OUT PERIOD. Each Holder agrees that, following the
effectiveness of the Registration Statement, such Holder will not effect any
sales of the Registrable Shares pursuant to the Registration Statement or any
filings with any state securities commission at any time after such Holder has
received notice from the Company to temporarily suspend sales as a result of the
occurrence or existence of any Suspension Event so that the Company promptly may
correct or update the Registration Statement or such filing. During such period,
the Company will not be obligated to effect redemptions of Units if such
redemptions and the issuance of Shares in connection therewith would violate the
Securities Act in the reasonable judgment of the Company. The Holder may
recommence effecting sales of the Shares pursuant to the Registration Statement
or such filings following further notice to such effect from the Company, which
notice shall be given by the Company not later than five (5) business days after
the conclusion of any such Suspension Event.

         12. ADDITIONAL SHARES. The Company, at its option, may register, under
the Registration Statement and any filings with any state securities commissions
filed pursuant to this

<PAGE>


                                      -10-


Agreement, any number of unissued shares of Common Stock or any shares of Common
Stock owned by any other shareholder or shareholders of the Company.

         13. CONTRIBUTION. If the indemnification provided for in Sections 8 and
9 is unavailable to an indemnified party with respect to any losses, claims,
damages, actions, liabilities, costs or expenses referred to therein or is
insufficient to hold the indemnified party harmless as contemplated therein,
then the indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, actions, liabilities, costs or expenses
in such proportion as is appropriate to reflect the relative fault of the
Company, on the one hand, and the Indemnitee, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,
actions, liabilities, costs or expenses as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the
Indemnitee, on the other hand, shall be determined by reference to, among other
factors, whether the untrue or alleged untrue statement of a material fact or
omission to state a material fact relates to information supplied by the Company
or in writing by the Indemnitee and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission; PROVIDED, HOWEVER, that in no event shall the obligation of any
indemnifying party to contribute under this Section 13 exceed the amount that
such indemnifying party would have been obligated to pay by way of
indemnification if the indemnification provided for under SECTIONS 8 or 9 hereof
had been available under the circumstances.

         The Company and the Holders agree that it would not be just and
equitable if contribution pursuant to this SECTION 13 were determined by PRO
RATA allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph.

         Notwithstanding the provisions of this SECTION 13, no Holder shall be
required to contribute any amount in excess of the amount by which the gross
proceeds from the sale of Shares exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission. No indemnified party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any indemnifying party who was not guilty
of such fraudulent misrepresentation.

         14. NO OTHER OBLIGATION TO REGISTER. Except as otherwise expressly
provided in this Agreement, the Company shall have no obligation to any Holder
to register the Registrable Shares under the Securities Act.

         15. AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified, or supplemented or waived without the prior written consent
of the Company and Holders holding in excess of two-thirds of the aggregate of
all Shares held by (or issuable to) all Holders.

         16. NOTICES. Except as set forth below, all notices and other
communications provided for or permitted hereunder shall be in writing and shall
be deemed to have been duly given if delivered (i) personally with proof of
receipt, or (ii) by registered or certified mail (return receipt requested),
postage prepaid, or (iii) by courier or overnight delivery service, or (iv) by
facsimile transmission, with confirmation of receipt, to the respective parties
