the Conversion Factor by the number of shares of the Successor Entity into which
one REIT Share is converted pursuant to such merger, consolidation or
combination, determined as of the date of such merger, consolidation or
combination. Any adjustment to the Conversion Factor shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event; provided, however, that if the General Partner
receives an Exchange Notice after the record date, but prior to the effective
date of such dividend, distribution, subdivision or combination, the Conversion
Factor shall be determined as if the General Partner had received the Exchange
Notice immediately prior to the record date for such dividend, distribution,
subdivision or combination.

hereof.

jurisdiction, whether now in existence or hereinafter in effect, either by such

         convertible or exchangeable securities of the Partnership having
         designations, preferences and other rights such that the economic
         interests are substantially similar to those of the Additional
         Securities, and (B) the General Partner (or the General Partner and the
         Original Limited Partner) contributes the proceeds from the issuance of
         such Additional Securities and from any exercise of rights contained in
         such Additional Securities, directly and through the General Partner
         (or the General Partner and the Original Limited Partner), to the
         Partnership; provided, however, that the General Partner is allowed to
         issue Additional Securities in connection with an acquisition of a
         Property or other asset to be held directly by the General Partner, but
         if and only if, such direct acquisition and issuance of Additional
         Securities have been approved and determined to be in the best
         interests of the General Partner and the Partnership by a majority of
         the Independent Directors. Without limiting the foregoing, the General
         Partner is expressly authorized to issue Additional Securities for less
         than fair market value, and to cause the Partnership to issue to the
         General Partner (or to the General Partner and the Original Limited
         Partner) corresponding Partnership Interests, so long as (1) the
         General Partner concludes in good faith that such issuance is in the
         best interests of the General Partner and the Partnership, including
         without limitation, the issuance of REIT Shares and corresponding
         Partnership Units pursuant to an employee share purchase plan providing
         for employee purchases of REIT Shares at a discount from fair market
         value or employee stock options that have an exercise price that is
         less than the fair market value of the REIT Shares, either at the time
         of issuance or at the time of exercise, and (2) the General Partner
         contributes directly or directly and through the Original Limited
         Partnership all proceeds from such issuance to the Partnership.

                                      -14-

         (b) Certain Deemed Contributions of Proceeds of Issuance of REIT
Shares. In connection with any and all issuances of REIT Shares, the General
Partner shall make directly or directly and through the Original Limited Partner
Capital Contributions to the Partnership of the proceeds therefrom, provided,
that if the proceeds actually received and contributed by the General Partner
are less than the gross proceeds of such issuance as a result of any
underwriter's discount or other fees or expenses paid or incurred in connection
with such issuance, then the General Partner (or the General Partner together
with the Original Limited Partner, as applicable) shall be deemed to have made
Capital Contributions to the Partnership in the aggregate amount of the gross
proceeds of such issuance and the Partnership shall be deemed simultaneously to
have paid such offering expenses in accordance with Section 6.05 hereof and in
connection with the required issuance of additional Partnership Units for such
Capital Contributions pursuant to Section 4.02(a) hereof.

         (c) Original Limited Partner Deemed Contributions. In the event the
Original Limited Partner elects to defer any distribution of cash hereunder to
be made to it pursuant to Section 5.02(a) hereof, then such amount shall be
deemed to be an additional contribution of capital to the Partnership by the
Original Limited Partner, which shall be added to the Original Limited Partner's
Capital Contribution to the Partnership and the Original Limited Partner's
Capital Account as established and maintained under Section 4.04 hereof.

4.03 ADDITIONAL FUNDING. If the General Partner determines that it is in the
best interests of the Partnership to provide for additional Partnership funds
("ADDITIONAL FUNDS") for any Partnership purpose, the General Partner may (a)
cause the Partnership to obtain such funds from outside borrowings, or (b) elect
to have the General Partner or any of its Affiliates provide such Additional
Funds to the Partnership through loans or otherwise.

4.04 CAPITAL ACCOUNTS. A separate capital account (a "CAPITAL ACCOUNT") shall be
established and maintained for each Partner in accordance with Regulations
Section 1.704-1(b)(2)(iv). If (a) a new or existing Partner acquires an
additional Partnership Interest in exchange for more than a de minimis Capital
Contribution, (b) the Partnership distributes to a Partner more than a de
minimis amount of Partnership property as consideration for the redemption of a
Partnership Interest, or (c) the Partnership is liquidated within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(g), the General Partner shall revalue the
property of the Partnership to its fair market value (as determined by the
General Partner, in its sole and absolute discretion, and taking into account
Section 7701(g) of the Code) in accordance with Regulations Section 1.704-
l(b)(2)(iv)(f). When the Partnership's property is revalued by the General
Partner, the Capital Accounts of the Partners shall be adjusted in accordance
with Regulations Sections 1.704-1(b)(2)(iv)(f) and (g), which generally require
such Capital Accounts to be adjusted to reflect the manner in which the
unrealized gain or loss inherent in such property (that has not been reflected
in the Capital Accounts previously) would be allocated among the Partners
pursuant to Section 5.01 hereof if there were a taxable disposition of such
property for its fair market value (as determined by the General Partner, in its
sole and absolute discretion, and taking into account Section 7701(g) of the
Code) on the date of the revaluation.

4.05 PERCENTAGE INTERESTS. If the number of outstanding Partnership Units
increases or decreases during a taxable year, each Partner's Percentage Interest
shall be adjusted by the General Partner effective as of the date of each such
increase or decrease to a percentage equal to

                                      -15-
<PAGE>

the number of Partnership Units held by such Partner divided by the aggregate
number of Partnership Units outstanding after giving effect to such increase or
decrease. In such event, the General Partner shall revalue the property of the
Partnership and the Capital Account for each Partner shall be adjusted as set
forth in Section 4.04 hereof. If the Partners' Percentage Interests are adjusted
pursuant to this Section 4.05, the Profit and Loss for the taxable year in which
the adjustment occurs shall be prorated between the part of the year ending on
the day when the Partnership's property is revalued by the General Partner and
the part of the year beginning on the following day and, as so divided, shall be
allocated to the Partners based on their Percentage Interests before adjustment,
and their adjusted Percentage Interests, respectively, either (a) as if the
taxable year had ended on the date of the adjustment or (b) based on the number
of days in each part. The General Partner, in its sole and absolute discretion,
shall determine which method shall be used to allocate Profit and Loss for the
taxable year in which an adjustment occurs, as may be required or permitted
under Section 706 of the Code.

4.06 NO INTEREST ON CONTRIBUTIONS. No Partner shall be entitled to interest on
its Capital Contribution.

4.07 RETURN OF CAPITAL CONTRIBUTIONS. No Partner shall be entitled to withdraw
any part of its Capital Contribution or its Capital Account or to receive any
distribution from the Partnership, except as specifically provided in this
Agreement. Except as otherwise provided herein, there shall be no obligation to
return to any Partner or withdrawn Partner any part of such Partner's Capital
Contribution for so long as the Partnership continues in existence.

4.08 NO THIRD-PARTY BENEFICIARY. No creditor or other third party having
dealings with the Partnership shall have the right to enforce the right or
obligation of any Partner to make Capital Contributions or loans or to pursue
any other right or remedy hereunder or at law or in equity, it being understood
and agreed that the provisions of this Agreement shall be solely for the benefit
of, and may be enforced solely by, the parties hereto and their respective
successors and assigns. None of the rights or obligations of the Partners herein
set forth to make Capital Contributions or loans to the Partnership shall be
deemed an asset of the Partnership for any purpose by any creditor or other
third party, nor may such rights or obligations be sold, transferred or assigned
by the Partnership or pledged or encumbered by the Partnership to secure any
debt or other obligation of the Partnership or of any of the Partners. In
addition, it is the intent of the parties hereto that no distribution to any
Limited Partner shall be deemed a return of money or other property in violation
of the Act. However, if any court of competent jurisdiction holds that,
notwithstanding the provisions of this Agreement, any Limited Partner is
obligated to return such money or property, such obligation shall be the
obligation of such Limited Partner and not of the General Partner. Without
limiting the generality of the foregoing, a deficit Capital Account of a Partner
shall not be deemed to be a liability of such Partner nor an asset or property
of the Partnership.

                         PROFIT AND LOSS; DISTRIBUTIONS

5.01 ALLOCATION OF PROFIT AND LOSS.

         (a) After giving effect to the special allocations set forth in
Sections 5.01(b), (c) and (d), Profit for each fiscal year of the Partnership
shall be allocated as follows: (i) first to the Partners, pro rata, in
accordance with and in proportion to their respective Partnership Interests, in
amounts equal to the amount of cash distributed to the Partners pursuant to
Section 5.02(a) hereof with respect to such fiscal year; (ii) second, to the
extent the amount of Profit for such fiscal year exceeds the amount of cash
distributed to the Partners pursuant to Section 5.02(a) hereof, such excess
shall be allocated to the General Partner and the Limited Partners in amounts
and in proportion to the cumulative Loss allocated to the General Partner
pursuant to clause (y) of this Section 5.01(a) and the cumulative Loss allocated
to the Limited Partners pursuant to clause (x) of this Section 5.01(a),
respectively; and (iii) finally, the balance, if any, of Profit shall be
allocated to the Partners in accordance with and in proportion to their
respective Percentage Interests. Notwithstanding the foregoing, however, it is
the intent of the Partners that allocations of Profit to the Limited Partners be
such that the amount of Profit allocated to each Limited Partner be equal to the
amount of income that would have been allocated to such Limited Partner with
respect to the applicable fiscal period if such Limited Partner had owned REIT
Shares equal in number to the number of Partnership Units owned by such Limited
Partner during such fiscal period, and if, for any reason, the foregoing
allocations of Profit result in any material variation from this concept, Profit
shall be allocated to each Limited Partner in an amount equal to the aggregate
amount of income that would have been allocated to such Limited Partner with
respect to the applicable fiscal period if such Limited Partner had owned REIT
Shares equal in number to the number of Partnership Units owned by such Limited
Partner during such fiscal period. After giving effect to the special
allocations set forth in Sections 5.01(b), (c) and (d), Loss for a fiscal year
of the Partnership shall be allocated as follows: (w) first, to the Partners,
pro rata, in accordance with and in proportion to their respective Partnership
Interests, until the cumulative Loss allocated to each Partner under this clause
(w) equals the cumulative Profit allocated to each Partner under clause (ii) of
this Section 5.01(a); (x) second, to the Limited Partners in an amount equal to
each such Limited Partner's Capital Account balance prior to the allocation made
under this clause (x); (y) third, to the General Partner in an amount equal to
the General Partner's Capital Account balance prior to the allocation made under
this clause (y); and (z) fourth, to the General Partner to the extent that any
further allocation of Loss to Limited Partners would result in any such Limited
Partners having a deficit balance in their Capital Accounts.

         (b) Notwithstanding any provision to the contrary herein, (i) any
expense of the Partnership that is a "nonrecourse deduction" within the meaning
of Regulations Section 1.704-2(b)(1) shall be allocated in accordance with the
Partners' respective Percentage Interests, (ii) any expense of the Partnership
that is a "partner nonrecourse deduction" within the meaning of Regulations
Section 1.704-2(i)(2) shall be allocated to the Partner that bears the "economic
risk of loss" of such deduction in accordance with Regulations Section 1.704-
2(i)(1), (iii) if there is a net decrease in Partnership Minimum Gain within the
meaning of Regulations Section 1.704-2(f)(1) for any Partnership taxable year,
then, subject to the exceptions set forth in Regulations

                                      -17-
<PAGE>

Section 1.704-2(f)(2), (3), (4) and (5), items of gain and income shall be
allocated among the Partners in accordance with Regulations Section 1.704-2(f)
and the ordering rules contained in Regulations Section 1.704-2(j), and (iv) if
there is a net decrease in Partner nonrecourse debt minimum gain within the
meaning of Regulations Section 1.704-2(i)(4) for any Partnership taxable year,
then, subject to the exceptions set forth in Regulations Section 1.704-2(g),
items of gain and income shall be allocated among the Partners, in accordance
with Regulations Section 1.704-2(i)(4) and the ordering rules contained in
Regulations Section 1.704-2(j). A Partner's "interest in partnership profits"
for purposes of determining its share of the nonrecourse liabilities of the
Partnership within the meaning of Regulations Section 1.752- 3(a)(3) shall be
such Partner's Percentage Interest.

         (c) If a Partner receives in any taxable year an adjustment,
allocation, or distribution described in subparagraphs (4), (5), or (6) of
Regulations Section 1.704-1(b)(2)(ii)(d) that causes or increases a deficit
balance in such Partner's Capital Account that exceeds the sum of such Partner's
shares of Partnership Minimum Gain and Partner nonrecourse debt minimum gain, as
determined in accordance with Regulations Sections 1.704-2(g) and 1.704-2(i),
such Partner shall be allocated specially for such taxable year (and, if
necessary, later taxable years) items of income and gain in an amount and manner
sufficient to eliminate such deficit Capital Account balance as quickly as
possible as provided in Regulations Section 1.704-1(b)(2)(ii)(d). After the
occurrence of an allocation of income or gain to a Partner in accordance with
this Section 5.01(c), to the extent permitted by Regulations Section 1.704-1(b),
items of expense or loss shall be allocated to such Partner in an amount
necessary to offset the income or gain previously allocated to such Partner
under this Section 5.01(c).

         (d) Loss shall not be allocated to a Limited Partner to the extent that
such allocation would cause a deficit in such Partner's Capital Account (after
reduction to reflect the items described in Regulations Section
1.704-1(b)(2)(ii)(d)(4), (5) and (6)) to exceed the sum of such Partner's shares
of Partnership Minimum Gain and Partner nonrecourse debt minimum gain. Any Loss
in excess of that limitation shall be allocated to the General Partner. After
the occurrence of an allocation of Loss to the General Partner in accordance
with this Section 5.01(d), to the extent permitted by Regulations Section
1.704-1(b), Profit shall be allocated to the General Partner in an amount
necessary to offset the Loss previously allocated to the General Partner under
this Section 5.01(d).

         (e) If a Partner transfers any part or all of its Partnership Interest,
the distributive shares of the various items of Profit and Loss allocable among
the Partners during such fiscal year of the Partnership shall be allocated
between the transferor and the transferee Partner either (i) as if the
Partnership's fiscal year had ended on the date of the transfer, or (ii) based
on the number of days of such fiscal year that each was a Partner without regard
to the results of Partnership activities in the respective portions of such
fiscal year in which the transferor and the transferee were Partners. The
General Partner, in its sole and absolute discretion, shall determine which
method shall be used to allocate the distributive shares of the various items of
Profit and Loss between the transferor and the transferee Partner.

         (f) "PROFIT" and "LOSS" and any items of income, gain, expense, or loss
referred to in this Agreement shall be determined in accordance with federal
income tax accounting principles, as modified by Regulations Section
1.704-(b)(2)(iv), except that Profit and Loss shall not include

                                      -18-
<PAGE>

items of income, gain and expense that are specially allocated pursuant to
Sections 5.01(b), 5.01(c), or 5.01(d). All allocations of income, Profit, gain,
Loss, and expense (and all items contained therein) for federal income tax
purposes shall be identical to all allocations of such items set forth in this
Section 5.01, except as otherwise required by Section 704(c) of the Code and
Regulations Section 1.704-1(b)(4). The General Partner shall have the authority,
in its sole and absolute discretion and without the need for consent from any
Partner, to elect the method or methods to be used by the Partnership for
allocating items of income, gain, expense and deductions as required by Section
704(c) of the Code, including election of a method that may result in one or
more Partners receiving or being allocated a disproportionately larger share of
items of Partnership income, gain, expense or deduction, and any such election
shall be binding on all Partners.

5.02 DISTRIBUTIONS OF CASH.

         (a) The Partnership shall distribute cash on a quarterly (or, at the
election of the General Partner, more frequent) basis, in an amount determined
by the General Partner in its sole and absolute discretion, to the Partners who
are Partners on the Partnership Record Date with respect to such quarter (or
other distribution period) in the following manner: (i) first, to the General
Partner in an amount equal to the GP Minimum Return with respect to the fiscal
year of the General Partner; (ii) second, to the Limited Partners pro rata among
them in proportion to the their respective Unpaid Return, if any, owing to each
such Limited Partners with respect to prior fiscal years, in an amount equal to
their respective Unpaid Return for such prior fiscal years owing to each such
Limited Partner; (iii) third, after the establishment of reasonable cash
reserves to meet REIT Expenses and other obligations of the Partnership, as
determined in the sole and absolute discretion of the General Partner, to the
General Partner and the Limited Partners in such aggregate amount as may be
determined by the General Partner in its sole and absolute discretion to be
allocated among the General Partner and the Limited Partners such that each
Limited Partner will receive an amount equal to its LP Return for such fiscal
year; and (iv) finally, to the Partners in accordance with and in proportion to
their respective Percentage Interests; provided, however, that if a new or
existing Partner acquires an additional Partnership Interest in exchange for a
Capital Contribution on any date other than a Partnership Record Date, the cash
distribution attributable to such additional Partnership Interest relating to
the Partnership Record Date next following the issuance of such additional
Partnership Interest shall be reduced to the proportion thereof which equals (i)
the number of days that such additional Partnership Interest is held by such
Partner divided by (ii) the number of days between such Partnership Record Date
and the immediately preceding Partnership Record Date. Notwithstanding the
foregoing, however, the Original Limited Partner may, in its sole and absolute
discretion, elect to defer any distribution to be made to it, in which case the
amount so deferred shall be deemed to be an additional Capital Contribution made
on behalf of the Original Limited Partner under Section 4.02(c) hereof, to be
distributed to the Original Limited Partner upon liquidation of the Partnership
under Section 5.06 hereof, or at such time as the Original Limited Partner may
otherwise be allowed to withdraw from the Partnership after the Transfer
Restriction Date.

         (b) Notwithstanding any other provision of this Agreement, the General
Partner is authorized to take any action that it determines to be necessary or
appropriate to cause the Partnership to comply with any withholding requirements
established under the Code or any other federal, state or local law including,
without limitation, the requirements of Sections 1441,

                                      -19-
<PAGE>

1442, 1445 and 1446 of the Code. To the extent that the Partnership is required
to withhold and pay over to any taxing authority any amount resulting from the
allocation or distribution of income to a Partner or its assignee (including by
reason of Section 1446 of the Code), either (i) if the actual amount to be
distributed to the Partner or assignee equals or exceeds the amount required to
be withheld by the Partnership, the amount withheld shall be treated as a
distribution of cash in the amount of such withholding to such Partner or
assignee, or (ii) if the actual amount to be distributed to the Partner or
assignee is less than the amount required to be withheld by the Partnership, the
amount required to be withheld shall be treated as a loan (a "PARTNERSHIP LOAN")
from the Partnership to the Partner or assignee on the day the Partnership pays
over such amount to a taxing authority. A Partnership Loan shall be repaid
through withholding by the Partnership with respect to subsequent distributions
to the applicable Partner or assignee. In the event that a Limited Partner (a
"DEFAULTING LIMITED PARTNER") fails to pay any amount owed to the Partnership
with respect to the Partnership Loan within 15 days after demand for payment
thereof is made by the Partnership on the Limited Partner, the General Partner,
in its sole and absolute discretion, may elect to make the payment to the
Partnership on behalf of such Defaulting Limited Partner. In such event, on the
date of payment, the General Partner shall be deemed to have extended a loan (a
"GENERAL PARTNER LOAN") to the Defaulting Limited Partner in the amount of the
payment made by the General Partner and shall succeed to all rights and remedies
of the Partnership against the Defaulting Limited Partner as to that amount.
Without limitation, the General Partner shall have the right to receive any
distributions that otherwise would be made by the Partnership to the Defaulting
Limited Partner until such time as the General Partner Loan has been paid in
full, and any such distributions so received by the General Partner shall be
treated as having been received by the Defaulting Limited Partner and
immediately paid to the General Partner. Any amounts treated as a Partnership
Loan or a General Partner Loan pursuant to this Section 5.02(b) shall bear
interest at the lesser of (A) the base rate on corporate loans at large United
States money center commercial banks, as published from time to time in The Wall
Street Journal, or (B) the maximum lawful rate of interest on such obligation,
such interest to accrue from the date the Partnership or the General Partner, as
applicable, is deemed to extend the loan until such loan is repaid in full.

         (c) To the extent not utilized for expenses of the Partnership or for
investment in additional Properties, the General Partner may, in its discretion,
cause the Partnership to distribute Net Capital Proceeds in such amount as shall
be determined by the General Partner in its discretion in accordance with the
provisions of Section 5.02(a) hereof.

         (d) In no event may a Partner receive a distribution of cash with
respect to a Partnership Unit if such Partner is entitled to receive a cash
dividend as the holder of record of a REIT Share for which all or part of such
Partnership Unit has been or will be exchanged, and the Unpaid Return with
respect to such Partnership Unit shall be deemed to be reduced by the amount of
any such cash dividend.

                                      -20-
<PAGE>

5.03 REIT DISTRIBUTION REQUIREMENTS. The General Partner shall use its
reasonable efforts to cause the Partnership to distribute amounts sufficient to
enable the General Partner to pay stockholder dividends that will allow the
General Partner to (a) meet its distribution requirement for qualification as a
REIT as set forth in Section 857 of the Code and (b) avoid any federal income or
excise tax liability imposed by the Code.

5.04 NO RIGHT TO DISTRIBUTIONS IN KIND. No Partner shall be entitled to demand
property other than cash in connection with any distributions by the
Partnership.

5.05 LIMITATIONS ON RETURN OF CAPITAL CONTRIBUTIONS. Notwithstanding any of the
provisions of this Article V, no Partner shall have the right to receive and the
General Partner shall not have the right to make a distribution that includes a
return of all or part of a Partner's Capital Contributions, unless after giving
effect to the return of a Capital Contribution, the sum of all Partnership
liabilities, other than the liabilities to a Partner for the return of its
Capital Contribution, does not exceed the fair market value of the Partnership's
assets.

5.06 DISTRIBUTIONS UPON LIQUIDATION. Upon liquidation of the Partnership, after
payment of, or adequate provision for, debts and obligations of the Partnership,
including any Partner loans, any remaining assets of the Partnership shall be
distributed to all Partners with positive Capital Accounts in accordance with
their respective positive Capital Account balances. For purposes of the
preceding sentence, the Capital Account of each Partner shall be determined
after all adjustments made in accordance with Sections 5.01 and 5.02 resulting
from Partnership operations and from all sales and dispositions of all or any
part of the Partnership's assets have been made. To the extent deemed advisable
by the General Partner, appropriate arrangements (including the use of a
liquidating trust) may be made to assure that adequate funds are available to
pay any contingent debts or obligations.

5.07 SUBSTANTIAL ECONOMIC EFFECT. It is the intent of the Partners that the
allocations of Profit and Loss under this Agreement have substantial economic
effect (or be consistent with the Partners' interests in the Partnership in the
case of the allocation of losses attributable to nonrecourse debt) within the
meaning of Section 704(b) of the Code as interpreted by the Regulations
promulgated pursuant thereto. Article V and other relevant provisions of this
Agreement shall be interpreted in a manner consistent with such intent.

                             RIGHTS, OBLIGATIONS AND
                          POWERS OF THE GENERAL PARTNER

6.01 MANAGEMENT OF THE PARTNERSHIP.

         (a) Except as otherwise expressly provided in this Agreement, the
General Partner shall have full, complete and exclusive discretion to manage and
control the business of the Partnership for the purposes herein stated, and
shall make all decisions affecting the business and assets of the Partnership.
Subject to the restrictions specifically contained in this Agreement, the powers
and obligations, as the context requires, of the General Partner shall include,
without limitation, the authority to take the following actions on behalf of the
Partnership:

         any real property and any other property or assets including, but not
         limited to notes, Mortgages, partnership or joint venture interests or

         Interests, or options, rights, warrants or appreciation rights relating
         to any Partnership Interests) of the Partnership;

         indebtedness by mortgage, deed of trust, pledge or other lien on the
         Partnership's assets;

                  (v) to pay, either directly or by reimbursement, for all
         operating costs and general administrative expenses of the Partnership
         to third parties or to the General Partner or its Affiliates as set
         forth in this Agreement;

                  (vi) to guarantee or become a co-maker of indebtedness of the
         General Partner or any Subsidiary thereof, refinance, increase the
         amount of, modify, amend or change the terms of, or extend the time for
         the payment of, any such guarantee or indebtedness, and secure such

         Agreement, including, without limitation, payment, either directly or
         by reimbursement, of all operating costs and general administrative
         expenses of the General Partner, the Partnership or any Subsidiary of
         either, to third parties or to the General Partner as set forth in this
         Agreement;

                  (viii) to lease all or any portion of any of the Partnership's
         assets, whether or not the terms of such leases extend beyond the

         the Partnership's assets so leased are to be occupied by the lessee,
         or, in turn, subleased in whole or in part to others, for such
         consideration and on such terms as the General Partner may determine;

                  (ix) to prosecute, defend, arbitrate, or compromise any and
         all claims or liabilities in favor of or against the Partnership, on
         such terms and in such manner as the General Partner may reasonably
         determine, and similarly, to prosecute, settle or defend litigation
         with respect to the Partners, the Partnership, or the Partnership's
         assets;

         any and all governmental agencies having jurisdiction over, or in any
         way affecting, the Partnership's assets or any other aspect of the
         Partnership business;

                  (xi) to make or revoke any election permitted or required of
         the Partnership by any taxing authority;

                  (xii) to maintain such insurance coverage for public
         liability, fire and casualty, and any and all other insurance for the
         protection of the Partnership, for the conservation of Partnership
         assets, or for any other purpose convenient or beneficial to the
         Partnership, in such amounts and such types, as it shall determine from
         time to time;

                  (xiii) to determine whether or not to apply any insurance
         proceeds for any Property to the restoration of such Property or to
         distribute the same;

         deem necessary or appropriate in connection with the Partnership
         business and to pay such persons remuneration as the General Partner
         may deem reasonable and proper;

                  (xv) to retain other services of any kind or nature in
         connection with Partnership business and to pay such remuneration as
         the General Partner may deem reasonable and proper for same;

                  (xvi) to negotiate and conclude agreements on behalf of the
         Partnership with respect to any of the rights, powers and authority
         conferred upon the General Partner;

         its Subsidiaries and any other Person in which it has an equity
         interest from time to time);

         capital expenditures, contingent liabilities, or any other valid
         Partnership purpose;

                  (xxi) to merge, consolidate or combine the Partnership with or
         into another Person;

                                      -23-
<PAGE>

                  (xxii) to do any and all acts and things necessary or prudent
         to ensure that the Partnership will not be classified as a "publicly
         traded partnership" for purposes of Section 7704 of the Code; and

                  (xxiii) to take such other action, execute, acknowledge, swear
         to or deliver such other documents and instruments, and perform any and
         all other acts that the General Partner deems necessary or appropriate
         for the formation, continuation and conduct of the business and affairs
         of the Partnership (including, without limitation, all actions
         consistent with allowing the General Partner at all times to qualify as
         a REIT unless the General Partner voluntarily terminates its REIT
         status) and to possess and enjoy all of the rights and powers of a
         general partner as provided by the Act.

         (b) Except as otherwise provided herein, to the extent the duties of
the General Partner require expenditures of funds to be paid to third parties,
the General Partner shall not have any obligations hereunder except to apply
Partnership funds to the extent that Partnership funds are reasonably available
to it for the performance of such duties, and nothing herein contained shall be
deemed to authorize or require the General Partner, in its capacity as such, to
expend its individual funds for payment to third parties or to undertake any
individual liability or obligation on behalf of the Partnership.

6.02 DELEGATION OF AUTHORITY. The General Partner may delegate any or all of its
powers, rights and obligations hereunder, and may appoint, employ, contract or
otherwise deal with any Person (including without limitation officers or other
agents of the Partnership or the General Partner appointed by the General
Partner) for the transaction of the business of the Partnership, which Person
may, under supervision of the General Partner, perform any acts or services for
the Partnership as the General Partner may approve.

6.03 INDEMNIFICATION AND EXCULPATION OF INDEMNITEES.

         (a) The Partnership shall indemnify an Indemnitee from and against any
and all losses, claims, damages, liabilities, joint or several, expenses
(including reasonable legal fees and expenses), judgments, fines, settlements,
and other amounts arising from any and all claims, demands, actions, suits or
proceedings, civil, criminal, administrative or investigative, that relate to
the operations of the Partnership as set forth in this Agreement in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, only if it is determined that (i) the Indemnitee acted in good faith
and (ii) that the Indemnitee reasonably believed that the act or omission was in
the Partnership's best interests, or if the act or omission was outside the
Indemnitee's official capacity as a general partner of the Partnership, that the
act or omission was at least not opposed to the Partnership's best interests.
Notwithstanding the foregoing, each Indemnitee shall be liable, responsible and
accountable, and the Partnership shall not be liable to an Indemnitee, other
than for reasonable expenses actually incurred by the Indemnitee with respect to
a proceeding in which (i) the Indemnitee is found liable on the basis that the
Indemnitee improperly received personal benefit, whether or not the benefit
resulted from an action taken in the Indemnitee's official capacity, or (ii) the
Indemnitee is found liable to the Partnership or the Limited Partners. The
Indemnitee shall not be indemnified in relation to a proceeding in which the
Indemnitee has been found liable for willful or intentional misconduct in the
performance of the Indemnitee's duty to the Partnership or the Limited Partners.
The

                                      -24-
<PAGE>

termination of any proceeding by judgment, order or settlement does not create a
presumption that the Indemnitee did not meet the requisite standard of conduct
set forth in this Section 6.03(a). The termination of any proceeding by
conviction or upon a plea of nolo contendere or its equivalent, or an entry of
an order of probation prior to judgment, does not alone determine that the
Indemnitee acted in a manner contrary to that specified in this Section 6.03(a).
Any indemnification pursuant to this Section 6.03 shall be made only out of the
assets of the Partnership.

         (b) The Partnership shall pay on behalf of or reimburse an Indemnitee
for reasonable expenses incurred by an Indemnitee who is a party to a proceeding
in advance of the final disposition of the proceeding upon receipt by the
Partnership of (i) a written affirmation by the Indemnitee of the Indemnitee's
good faith belief that the standard of conduct necessary for indemnification by
the Partnership as authorized in this Section 6.03 has been met, and (ii) a
written undertaking by or on behalf of the Indemnitee to repay the amount so
paid or reimbursed by the Partnership if it shall ultimately be determined that
the standard of conduct has not been met or it is ultimately determined that
indemnification of the Indemnitee is otherwise prohibited by the Act.

         (c) The Indemnification provided by this Section 6.03 shall be in
addition to any other rights to which an Indemnitee or any other Person may be
entitled under any agreement, pursuant to any vote of the Partners, as a matter
of law or otherwise, and shall continue as to an Indemnitee who has ceased to
serve in such capacity.

         (d) The Partnership may purchase and maintain insurance or establish
other arrangements, including without limitation trust arrangements and letters
of credit on behalf of or to secure indemnification obligations owed to the
Indemnitees and such other Persons as the General Partner shall determine
against any liability that may be asserted against or expenses that may be
incurred by such Person in connection with the Partnership's activities,
regardless of whether the Partnership would have the power to indemnify such
Person against such liability under the provisions of this Agreement.

         (e) For purposes of this Section 6.03, (i) the Partnership shall be
deemed to have requested an Indemnitee to serve as a fiduciary of an employee
benefit plan whenever the performance by the Indemnitee of its duties to the
Partnership also imposes duties on the Indemnitee, or otherwise involves
services by the Indemnitee to the plan or participants or beneficiaries of the
plan; (ii) excise taxes assessed on an Indemnitee with respect to an employee
benefit plan pursuant to applicable law shall constitute fines within the
meaning of this Section 6.03; and (iii) actions taken or omitted by the
Indemnitee with respect to an employee benefit plan in the performance of its
duties for a purpose reasonably believed by it to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is not opposed to the best interests of the Partnership.

         (f) In no event may an Indemnitee subject the Limited Partners to
personal liability by reason of the indemnification provisions set forth in this
Agreement.

         (g) An Indemnitee shall not be denied indemnification in whole or in
part under this Section 6.03 because the Indemnitee had an interest in the
transaction with respect to which the

                                      -25-
<PAGE>

indemnification applies if the transaction was otherwise permitted by the terms
of this Agreement.

         (h) The provisions of this Section 6.03 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights in or be for the benefit of any other Persons.

6.04 LIABILITY OF THE GENERAL PARTNER.

         (a) Notwithstanding anything to the contrary set forth in this
Agreement, the General Partner shall not be liable for monetary damages to the
Partnership or any Partners for losses sustained or liabilities incurred as a
result of errors in judgment or any act or omission if the General Partner acted
in good faith. The General Partner shall not be in breach of any duty that the
General Partner may owe to the Limited Partners or the Partnership or any other
Persons under this Agreement or of any duty stated or implied by law or equity,
provided, the General Partner, acting in good faith, abides by the terms of this
Agreement. In addition, to the extent the General Partner or any officer,
director, employee, agent or stockholder of the General Partner performs its
duties in accordance with the standards provided by the Act, as it may be
amended from time to time, or under any successor statute thereto, such Person
or Persons shall have no liability by reason of being or having been the General
Partner, or by reason of being an officer, director, employee, agent or
stockholder of the General Partner. To the maximum extent that the Act and the
general laws of the State of Texas, in effect from time to time, permit
limitation of the liability of general partners of a limited partnership, the
General Partner and its officers, directors, employees, agents and stockholders
shall not be liable to the Partnership or to any Partner for money damages
except to the extent that (i) the General Partner or its officers, directors,
employees, agents or stockholders actually received an improper benefit or
profit in money, property or services, in which case the liability shall not
exceed the amount of the benefit or profit in money, property or services
actually received; or (ii) a judgment or other final adjudication adverse to the
General Partner or one or more of its officers, directors, employees, agents or
stockholders is entered in a proceeding based on a finding in the proceeding
that the action or failure to act of the General Partner or one or more of its
officers, directors, employees, agents or stockholders was the result of active
and deliberate dishonesty and was material to the cause of action adjudicated in
the proceeding. Neither the amendment nor repeal of this Section 6.04(a), nor
the adoption or amendment of any other provision of this Agreement inconsistent
with this Section 6.04(a), shall apply to or affect in any respect the
applicability of the preceding sentence with respect to any act or failure to
act which occurred prior to such amendment, repeal or adoption. In the absence
of any Texas statute limiting the liability of the General Partner or its
directors or officers for money damages in a suit by or on behalf of the
Partnership or by any Partner, the General Partner and the officers, directors,
employees, agents and stockholders of the General Partner shall not be liable to
the Partnership or to any Partner for money damages except to the extent that
(i) the General Partner or one or more of its officers, directors, employees,
agents or stockholders actually received an improper benefit or profit in money,
property or services, in which case the liability shall not exceed the amount of
the benefit or profit in money, property or services actually received; or (ii)
a judgment or other final adjudication adverse to the General Partner or one or
more of its officers, directors, employees, agents or stockholders is entered in
a proceeding based on a finding in the proceeding that the action of the General
Partner or one or more of its officers, directors, employees or stockholders

                                      -26-
<PAGE>

action or failure to act was the result of active and deliberate dishonesty and
was material to the cause of action adjudicated in the proceeding.

         (b) The Limited Partners expressly acknowledge that the General Partner
is acting on behalf of the Partnership, itself and its stockholders
collectively, that the General Partner is under no obligation to consider the
separate interests of the Limited Partners (including, without limitation, the
tax consequences to Limited Partners or the tax consequences of some, but not
all, of the Limited Partners) in deciding whether to cause the Partnership to
take (or decline to take) any actions. In the event of a conflict between the
interests of its stockholders on the one hand and the Limited Partners on the
other, the General Partner shall endeavor in good faith to resolve the conflict
in a manner not adverse to either its stockholders or the Limited Partners;
provided, however, that for so long as the General Partner directly owns a
controlling interest in the Partnership, any such conflict that the General
Partner, in its sole and absolute discretion, determines cannot be resolved in a
manner not adverse to either its stockholders or the Limited Partners shall be
resolved in favor of its stockholders. The General Partner shall not be liable
for monetary damages for losses sustained, liabilities incurred, or benefits not
derived by Limited Partners in connection with such decisions, provided that the
General Partner has acted in good faith.

         (c) Subject to its obligations and duties as General Partner set forth
in Section 6.01 hereof, the General Partner may exercise any of the powers
granted to it under this Agreement and perform any of the duties imposed upon it
hereunder either directly or by or through its agents. The General Partner shall
not be responsible for any misconduct or negligence on the part of any such
agent appointed by it in good faith.

         (d) Notwithstanding any other provisions of this Agreement or the Act,
any action of the General Partner on behalf of the Partnership or any decision
of the General Partner to refrain from acting on behalf of the Partnership,
undertaken in the good faith belief that such action or omission is necessary or
advisable in order to (i) protect the ability of the General Partner to continue
to qualify as a REIT or (ii) prevent the General Partner from incurring any
taxes under Section 857, Section 4981, or any other provision of the Code, is
expressly authorized under this Agreement and is deemed approved by all of the
Limited Partners.

         (e) Any amendment, modification or repeal of this Section 6.04 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's liability to the Partnership and the
Limited Partners under this Section 6.04 as in effect immediately prior to such
amendment, modification or repeal with respect to matters occurring, in whole or
in part, prior to such amendment, modification or repeal, regardless of when
claims relating to such matters may arise or be asserted.

6.05 REIMBURSEMENT OF GENERAL PARTNER.

         (a) Except as provided in this Section 6.05 and elsewhere in this
Agreement (including the provisions of Articles V and VI regarding
distributions, payments, and allocations to which it may be entitled), the
General Partner shall not be compensated for its services as general partner of
the Partnership.

                                      -27-
<PAGE>

         (b) The General Partner shall be reimbursed on a monthly basis, or such
other basis as the General Partner may determine in its sole and absolute
discretion, for all REIT Expenses and Administrative Expenses.

6.06 OUTSIDE ACTIVITIES. Subject to Section 6.08 hereof, the Articles of
Incorporation and any agreements entered into by the General Partner or its
Affiliates with the Partnership or a Subsidiary, or any officer, director,
employee, agent, trustee, Affiliate or stockholder of the General Partner, the
General Partner shall be entitled to and may have business interests and engage
in business activities in addition to those relating to the Partnership,
including business interests and activities substantially similar or identical
to those of the Partnership. Neither the Partnership nor any of the Limited
Partners shall have any rights by virtue of this Agreement in any such business
ventures, interests or activities. None of the Limited Partners or any other
Person shall have any rights by virtue of this Agreement or the partnership
relationship established hereby in any such business ventures, interests or
activities, and the General Partner shall have no obligation pursuant to this
Agreement to offer any interest in any such business ventures, interests and
activities to the Partnership or any Limited Partner, even if such opportunity
is of a character which. if presented to the Partnership or any Limited Partner,
could be taken by such Person.

6.07 EMPLOYMENT OR RETENTION OF AFFILIATES.

         (a) Any Affiliate of the General Partner may be employed or retained by
the Partnership and may otherwise deal with the Partnership (whether as an
advisor, buyer, lessor, lessee, manager, property management agent, asset
manager, furnisher of goods or services, broker, agent, lender or otherwise) and
may receive from the Partnership any compensation, price, or other payment
therefor which the General Partner determines to be fair and reasonable.

         (b) The Partnership may lend or contribute to its Subsidiaries or other
Persons in which it has an equity investment, and such Persons may borrow funds
from the Partnership, on terms and conditions established in the sole and
absolute discretion of the General Partner. The foregoing authority shall not
create any right or benefit in favor of any Subsidiary or any other Person.

         (c) The Partnership may transfer assets to joint ventures, limited
liability companies, other partnerships, corporations or other business entities
in which it is or thereby becomes a participant upon such terms and subject to
such conditions as the General Partner deems to be consistent with this
Agreement and applicable law.

         (d) Except as expressly permitted by this Agreement, neither the
General Partner nor any of its Affiliates shall sell, transfer or convey any
property to, or purchase any property from, the Partnership, directly or
indirectly, except pursuant to transactions that are on terms that are fair and
reasonable to the Partnership.

6.08 GENERAL PARTNER PARTICIPATION. The General Partner agrees that all business
activities of the General Partner, including activities pertaining to the
acquisition, development or ownership of commercial real property or other
property, including Mortgages, shall be conducted through the Partnership or one
or more Subsidiary Partnerships; provided, however,

                                      -28-
<PAGE>

that the General Partner is allowed to make a direct acquisition, but if and
only if, such acquisition is made in connection with the issuance of Additional
Securities, which direct acquisition and issuance have been approved and
determined to be in the best interests of the General Partner and the
Partnership by a majority of the Independent Directors.

6.09 TITLE TO PARTNERSHIP ASSETS. Partnership assets, whether real, personal or
mixed and whether tangible or intangible, shall be deemed to be owned by the
Partnership as an entity, and no Partner, individually or collectively, shall
have any ownership interest in such Partnership assets or any portion thereof;
provided, that title to any or all of the Partnership assets may be held in the
name of the Partnership, the General Partner or one or more nominees, as the
General Partner may determine, including Affiliates of the General Partner. The
General Partner hereby declares and warrants that any Partnership assets for
which legal title is held in the name of the General Partner or any nominee or
Affiliate of the General Partner shall be held by such Person for the use and
benefit of the Partnership in accordance with the provisions of this Agreement;
provided, that the General Partner shall use its best efforts to cause legal
title to such assets to be vested in the Partnership as soon as reasonably
practicable. All Partnership assets shall be recorded as the property of the
Partnership in its books and records, irrespective of the name in which legal
title to such Partnership assets is held.

6.10 MISCELLANEOUS. In the event the General Partner redeems any REIT Shares,
then the General Partner shall cause the Partnership to purchase from the
General Partner or the Original Limited Partner a number of Partnership Units
determined by, and based upon, the application of the Conversion Factor on the
same terms upon which the General Partner redeemed such REIT Shares. Moreover,
if the General Partner makes a cash tender offer or other offer to acquire REIT
Shares, then the General Partner shall cause the Partnership to make a
corresponding offer to the General Partner or the Original Limited Partner to
acquire an equal number of Partnership Units held by the General Partner. In the
event any REIT Shares are redeemed by the General Partner pursuant to such
offer, the Partnership shall redeem an equivalent number of the General
Partner's or the Original Limited Partner's Partnership Units for an equivalent
purchase price based on the application of the Conversion Factor.

                                   ARTICLE VII

                           CHANGES IN GENERAL PARTNER

7.01 TRANSFER OF THE GENERAL PARTNER'S PARTNERSHIP INTEREST.

         (a) The General Partner shall not transfer all or any portion of its
General Partnership Interest or withdraw as General Partner except as provided
in or in connection with a transaction contemplated by Sections 7.01(c), 7.01(d)
or 7.01(e).

         (b) The General Partner agrees that the Percentage Interest for it will
at all times, be in the aggregate, at least 0.1%.

         (c) Except as otherwise provided in Section 7.01(d) or (e) hereof, the
General Partner shall not engage in any merger, consolidation or other
combination with or into another Person or sale of all or substantially all of
its assets (other than in connection with a change in the

                                      -29-
<PAGE>

General Partner's state of incorporation or organizational form), which, in any
such case, results in a change of control of the General Partner (a
"TRANSACTION"), unless:

                  (i) the consent of Limited Partners holding more than 50% of
         the Percentage Interests of the Limited Partners is obtained; or

                  (ii) as a result of such Transaction all Limited Partners are
         granted the right to receive for each Partnership Unit an amount of
         cash, securities, or other property equal to the product of the
         Conversion Factor and the greatest amount of cash, securities or other
         property paid in the Transaction to a holder of one REIT Share in
         consideration of the transfer of one REIT Share; provided, that if, in
         connection with the Transaction, a purchase, tender or exchange offer
         ("OFFER") shall have been made to and accepted by the holders of more
         than 50% of the outstanding REIT Shares, each holder of Partnership
         Units shall be given the option to exchange its Partnership Units for
         the greatest amount of cash, securities, or other property which a
         Limited Partner would have received had it (A) exercised its Exchange
         Right and (B) sold, tendered or exchanged pursuant to the Offer the
         REIT Shares received upon exercise of the Exchange Right immediately
         prior to the expiration of the Offer; or

                  (iii) the General Partner is the surviving entity in the
         Transaction and either (A) the holders of REIT Shares do not receive
         cash, securities, or other property in the Transaction or (B) all
         Limited Partners (other than the General Partner or any Subsidiary)
         receive an amount of cash, securities, or other property (expressed as
         an amount per REIT Share) that is no less than the product of the
         Conversion Factor and the greatest amount of cash, securities, or other
         property (expressed as an amount per REIT Share) received in the
         Transaction by any holder of REIT Shares.

         (d) Notwithstanding Section 7.01(c), the General Partner may merge with
or into or consolidate with another entity if immediately after such merger or
consolidation (i) substantially all of the assets of the successor or surviving
entity (the "Survivor"), other than Partnership Units held by the General
Partner, are contributed, directly or indirectly, to the Partnership as a
Capital Contribution in exchange for Partnership Units with a fair market value
equal to the value of the assets so contributed as determined by the Survivor in
good faith and (ii) the Survivor expressly agrees to assume all obligations of
the General Partner, as appropriate, hereunder. Upon such contribution and
assumption, the Survivor shall have the right and duty to amend this Agreement
as set forth in this Section 7.01(d). The Survivor shall in good faith arrive at
a new method for the calculation of the Cash Amount, the REIT Shares Amount and
the Conversion Factor for a Partnership Unit after any such merger or
consolidation so as to approximate the existing method for such calculation as
closely as reasonably possible. Such calculation shall take into account, among
other things, the kind and amount of securities, cash and other property that
was receivable upon such merger or consolidation by a holder of REIT Shares or
options, warrants or other rights relating thereto, and which a holder of
Partnership Units could have acquired had such Partnership Units been exchanged
immediately prior to such merger or consolidation. Such amendment to this
Agreement shall provide for adjustments to such method of calculation, which
shall be as nearly equivalent as may be practicable to the adjustments provided
for herein with respect to the Conversion Factor. The Survivor also shall in
good faith modify the definition of REIT Shares and make such amendments to
Section 8.05 hereof so as to approximate the

                                      -30-
<PAGE>

existing rights and obligations set forth in Section 8.05 as closely as
reasonably possible. The above provisions of this Section 7.01(d) shall
similarly apply to successive mergers or consolidations permitted hereunder.

         In respect of any transaction described in the preceding paragraph, the
General Partner is required to use its commercially reasonable efforts to
structure such transaction to avoid causing the Limited Partners to recognize a
gain for federal income tax purposes by virtue of the occurrence of or their
participation in such transaction, provided, such efforts are consistent with
the exercise of the Board of Directors' fiduciary duties to the stockholders of
the General Partner under applicable law.

         (e) Notwithstanding Section 7.01(c),

                  (i) a General Partner may transfer all or any portion of its
         General Partnership Interest to (A) a wholly-owned Subsidiary of such
         General Partner or (B) the owner of all of the ownership interests of
         such General Partner, and following a transfer of all of its General
         Partnership Interest, may withdraw as General Partner; and

                  (ii) the General Partner may engage in a transaction not
         required by law or by the rules of any national securities exchange on
         which the REIT Shares are listed to be submitted to the vote of the
         holders of the REIT Shares.

7.02 ADMISSION OF A SUBSTITUTE OR ADDITIONAL GENERAL PARTNER. A Person shall be
admitted as a substitute or additional General Partner of the Partnership only
if the following terms and conditions are satisfied:

         (a) the Person to be admitted as a substitute or additional General
Partner shall have accepted and agreed to be bound by all the terms and
provisions of this Agreement by executing a counterpart hereof and such other
documents or instruments as may be required or appropriate in order to effect
the admission of such Person as a General Partner, a certificate evidencing the
admission of such Person as a General Partner shall have been filed for
recordation and all other actions required by Section 2.05 hereof in connection
with such admission shall have been performed;

         (b) if the Person to be admitted as a substitute or additional General
Partner is a corporation or a partnership, it shall have provided the
Partnership with evidence satisfactory to counsel for the Partnership of such
Person's authority to become a General Partner and to be bound by the terms and
provisions of this Agreement; and

         (c) counsel for the Partnership shall have rendered an opinion (relying
on such opinions from other counsel in the state or any other jurisdiction as
may be necessary) that the admission of the Person to be admitted as a
substitute or additional General Partner is in conformity with the Act, and that
none of the actions taken in connection with the admission of such Person as a
substitute or additional General Partner will cause (i) the Partnership to be
classified other than as a partnership for federal income tax purposes, or (ii)
the loss of any Limited Partner's limited liability.

7.03 EFFECT OF BANKRUPTCY, WITHDRAWAL, DEATH OR DISSOLUTION OF A GENERAL
PARTNER.

         (a) Upon the occurrence of an Event of Bankruptcy as to a General
Partner (and its removal pursuant to Section 7.04(a) hereof) or the death,
withdrawal, removal or dissolution of a General Partner (except that, if a
General Partner is, on the date of such occurrence a partnership, the
withdrawal, death, dissolution, Event of Bankruptcy as to, or removal of a
partner in, such partnership shall be deemed not to be a dissolution of such
General Partner if the business of such General Partner is continued by the
remaining partner or partners thereof), the Partnership shall be dissolved and
terminated unless the Partnership is continued pursuant to Section 7.03(b)
hereof. The merger of the General Partner with or into any entity that is
admitted as a substitute or successor General Partner pursuant to Section 7.02
hereof shall not be deemed to be the withdrawal, dissolution or removal of the
General Partner.

         (b) Following the occurrence of an Event of Bankruptcy as to a General
Partner (and its removal pursuant to Section 7.04(a) hereof) or the death,
withdrawal, removal or dissolution of a General Partner (except that, if a
General Partner is, on the date of such occurrence a partnership, the
withdrawal, death, dissolution, Event of Bankruptcy as to, or removal of a
partner in, such partnership shall be deemed not to be a dissolution of such
General Partner if the business of such General Partner is continued by the
remaining partner or partners thereof), the Limited Partners, within 90 days
after such occurrence, may elect to continue the business of the Partnership for
the balance of the term specified in Section 2.04 hereof by selecting, subject
to Section 7.02 hereof and any other provisions of this Agreement, a substitute
General Partner by consent of a majority in interest of the Limited Partners. If
the Limited Partners elect to continue the business of the Partnership and admit
a substitute General Partner, the relationship with the Partners and of any
Person who has acquired an interest of a Partner in the Partnership shall be
governed by this Agreement.

7.04 REMOVAL OF A GENERAL PARTNER.

         (a) Upon the occurrence of an Event of Bankruptcy as to, or the
dissolution of, a General Partner, such General Partner shall be deemed to be
removed automatically; provided, however, that if a General Partner is on the
date of such occurrence a partnership, the withdrawal, death, dissolution, Event
of Bankruptcy as to or removal of a partner in such partnership shall be deemed
not to be a dissolution of the General Partner if the business of such General
Partner is continued by the remaining partner or partners thereof. The Limited
Partners may not remove the General Partner, with or without cause.

         (b) If a General Partner has been removed pursuant to this Section 7.04
and the Partnership is continued pursuant to Section 7.03 hereof, such General
Partner shall promptly transfer and assign its General Partnership Interest in
the Partnership to the substitute General Partner approved by a majority in
interest of the Limited Partners in accordance with Section 7.03(b) hereof and
otherwise admitted to the Partnership in accordance with Section 7.02 hereof. At
the time of assignment, the removed General Partner shall be entitled to receive
from the substitute General Partner the fair market value of the General
Partnership Interest of such removed General Partner as reduced by any damages
caused to the Partnership by such General Partner's removal. Such fair market
value shall be determined by an appraiser mutually agreed upon by the General
Partner and Limited Partners holding more than 50% of the Percentage

                                      -32-
<PAGE>

Interests of the Limited Partners within 10 days following the removal of the
General Partner. In the event that the parties are unable to agree upon an
appraiser, the removed General Partner and Limited Partners holding more than
50% of the Percentage Interests of the Limited Partners shall each select an
appraiser. Each such appraiser shall complete an appraisal of the fair market
value of the removed General Partner's General Partnership Interest within 30
days of the General Partner's removal, and the fair market value of the removed
General Partner's General Partnership Interest shall be the average of the two
appraisals; provided, however, that if the higher appraisal exceeds the lower
appraisal by more than 20% of the amount of the lower appraisal, the two
appraisers, no later than 40 days after the removal of the General Partner,
shall select a third appraiser who shall complete an appraisal of the fair
market value of the removed General Partner's General Partnership Interest no
later than 60 days after the removal of the General Partner. In such case, the
fair market value of the removed General Partner's General Partnership Interest
shall be the average of the two appraisals closest in value.

         (c) The General Partnership Interest of a removed General Partner,
during the time after removal until the date of transfer under Section 7.04(b),
shall be converted to that of a special Limited Partner; provided, however, such
removed General Partner shall not have any rights to participate in the
management and affairs of the Partnership, and shall not be entitled to any
portion of the income, expense, Profit, gain or Loss allocations or cash
distributions allocable or payable, as the case may be, to the Limited Partners.
Instead, such removed General Partner shall receive and be entitled only to
retain distributions or allocations of such items that it would have been
entitled to receive in its capacity as General Partner, until the transfer is
effective pursuant to Section 7.04(b).

         (d) All Partners shall have given and hereby do give such consents,
shall take such actions and shall execute such documents as shall be legally
necessary and sufficient to effect all the foregoing provisions of this Section
7.04.

                                  ARTICLE VIII

                             RIGHTS AND OBLIGATIONS
                             OF THE LIMITED PARTNERS

8.01 MANAGEMENT OF THE PARTNERSHIP. The Limited Partners shall not participate
in the management or control of Partnership business nor shall they transact any
business for or on behalf of the Partnership, nor shall they have the power to
sign for or bind the Partnership, such powers being vested solely and
exclusively in the General Partner.

8.02 POWER OF ATTORNEY. Each Limited Partner hereby irrevocably appoints the
General Partner its true and lawful attorney-in-fact, who may act for each
Limited Partner and in its name, place and stead, and for its use and benefit,
sign, acknowledge, swear to, deliver, file or record, at the appropriate public
offices, any and all documents, certificates, and instruments as may be deemed
necessary or desirable by the General Partner to carry out fully the provisions
of this Agreement and the Act in accordance with their terms, which power of
attorney is coupled with an interest and shall survive the death, dissolution or
legal incapacity of the Limited Partner, or the transfer by the Limited Partner
of any part or all of its Partnership Interest.

                                      -33-
<PAGE>

8.03 LIMITATION ON LIABILITY OF LIMITED PARTNERS. No Limited Partner shall be
liable for any debts, liabilities, contracts or obligations of the Partnership.
A Limited Partner shall be liable to the Partnership only to make payments of
its Capital Contribution, if any, as and when due hereunder. After its Capital
Contribution is fully paid, no Limited Partner shall, except as otherwise
required by the Act, be required to make any further Capital Contributions or
other payments or lend any funds to the Partnership.

8.04 OWNERSHIP BY LIMITED PARTNER OF CORPORATE GENERAL PARTNER OR AFFILIATE. No
Limited Partner shall at any time, either directly or indirectly, own any stock
or other interest in the General Partner or in any Affiliate thereof, if such
ownership by itself or in conjunction with other stock or other interests owned
by other Limited Partners would, in the opinion of counsel for the Partnership,
jeopardize the classification of the Partnership as a partnership for federal
income tax purposes. The General Partner shall be entitled to make such
reasonable inquiry of the Limited Partners as is required to establish
compliance by the Limited Partners with the provisions of this Section 8.04.

8.05 EXCHANGE RIGHT.

         (a) Subject to Sections 8.05(b), 8.05(c), 8.05(d) and 8.05(e) hereof,
and subject to the potential modification of any rights or obligations provided
for herein by agreement(s) between the Partnership and any one or more Limited
Partners with respect to Partnership Units held by them, each Limited Partner
shall have the right (the "EXCHANGE RIGHT") to require the Partnership to redeem
on a Specified Exchange Date all or a portion of the Partnership Units held by
such Limited Partner at an exchange price equal to and in the form of the Cash
Amount to be paid by the Partnership; provided, that such Partnership Units
shall have been outstanding for at least one year. The Exchange Right shall be
exercised pursuant to the delivery of an Exchange Notice to the Partnership
(with a copy to the General Partner) by the Limited Partner who is exercising
the Exchange Right (the "EXCHANGING PARTNER"); provided, however, that the
Partnership shall not be obligated to satisfy such Exchange Right if the General
Partner elects to purchase the Partnership Units subject to the Exchange Notice
pursuant to Section 8.05(b); and provided further, that no Limited Partner may
deliver more than two Exchange Notices during each calendar year. A Limited
Partner may not exercise the Exchange Right for less than 1,000 Partnership
Units or, if such Limited Partner holds less than 1,000 Partnership Units, all
of the Partnership Units held by such Partner. The Exchanging Partner shall have
no right, with respect to any Partnership Units so exchanged, to receive any
distribution paid with respect to such Partnership Units if the record date for
such distribution is on or after the Specified Exchange Date.

         (b) Notwithstanding the provisions of Section 8.05(a), a Limited
Partner that exercises the Exchange Right shall be deemed to have also offered
to sell the Partnership Units described in the Exchange Notice to the General
Partner, and the General Partner may, in its sole and absolute discretion, elect
to purchase directly and acquire such Partnership Units by paying to the
Exchanging Partner either the Cash Amount or the REIT Shares Amount, as elected
by the General Partner (in its sole and absolute discretion), on the Specified
Exchange Date, whereupon the General Partner shall acquire the Partnership Units
offered for exchange by the Exchanging Partner and shall be treated for all
purposes of this Agreement as the owner of such Partnership Units. If the
General Partner shall elect to exercise its right to purchase Partnership Units
under

                                      -34-
<PAGE>

this Section 8.05(b) with respect to an Exchange Notice, it shall so notify the
Exchanging Partner within five business days after the receipt by the General
Partner of such Exchange Notice. Unless the General Partner (in its sole and
absolute discretion) shall exercise its right to purchase Partnership Units from
the Exchanging Partner pursuant to this Section 8.05(b), the General Partner
shall have no obligation to the Exchanging Partner or the Partnership with
respect to the Exchanging Partner's exercise of an Exchange Right. In the event
the General Partner shall exercise its right to purchase Partnership Units with
respect to the exercise of an Exchange Right in the manner described in the
first sentence of this Section 8.05(b), the Partnership shall have no obligation
to pay any amount to the Exchanging Partner with respect to such Exchanging
Partner's exercise of such Exchange Right, and each of the Exchanging Partner
and the General Partner shall treat the transaction between the General Partner
and the Exchanging Partner for federal income tax purposes as a sale of the
Exchanging Partner's Partnership Units to the General Partner. Each Exchanging
Partner agrees to execute such documents as the General Partner may reasonably
require in connection with the issuance of REIT Shares to such Exchanging
Partner upon exercise of its Exchange Right.

         (c) Notwithstanding the provisions of Sections 8.05(a) and 8.05(b), a
Limited Partner shall not be entitled to exercise the Exchange Right if the
delivery of REIT Shares to such Partner on the Specified Exchange Date by the
General Partner pursuant to Section 8.05(b) (regardless of whether or not the
General Partner would in fact exercise its rights under Section 8.05(b)) would
(i) result in such Partner or any other person owning, directly or indirectly,
REIT Shares in excess of the ownership limitations described in the Articles of
Incorporation and calculated in accordance therewith, (ii) result in REIT Shares
being owned by fewer than 100 persons (determined without reference to any rules
of attribution), except as provided in the Articles of Incorporation, (iii)
result in the General Partner being "closely held" within the meaning of Section
856(h) of the Code, (iv) cause the General Partner to own, directly or
constructively, 10% or more of the ownership interests in a tenant of the
General Partner's, the Partnership's, or a Subsidiary Partnership's real
property within the meaning of Section 856(d)(2)(B) of the Code, or (v) cause
the acquisition of REIT Shares by such Partner to be "integrated" with any other
distribution of REIT Shares for purposes of complying with the registration
provisions of the Securities Act. The General Partner, in its sole and absolute
discretion, may waive any of the restrictions on exchange set forth in this
Section 8.05(c); provided, however, that in the event any such restriction is
waived, the Exchanging Partner shall be paid the Cash Amount.

         (d) Any Cash Amount to be paid to an Exchanging Partner pursuant to
this Section 8.05 shall be paid on the Specified Exchange Date; provided,
however, that the General Partner may elect to cause the Specified Exchange Date
to be delayed for up to 180 days to the extent required for the General Partner
to cause additional REIT Shares to be issued to provide financing to be used to
make such payment of the Cash Amount. Notwithstanding the foregoing, the General
Partner agrees to use its best efforts to cause the closing of the acquisition
of exchanged Partnership Units hereunder to occur as quickly as reasonably
possible.

         (e) Notwithstanding any other provision of this Agreement, the General
Partner shall place appropriate restrictions on the ability of the Limited
Partners to exercise their Exchange Rights as and if deemed necessary to ensure
that the Partnership does not constitute a "publicly traded partnership" under
Section 7704 of the Code. If and when the General Partner determines

                                      -35-
<PAGE>

that imposing such restrictions is necessary, the General Partner shall give
prompt written notice thereof (a "RESTRICTION NOTICE") to each of the Limited
Partners, which notice shall be accompanied by a copy of an opinion of counsel
to the Partnership which states that, in the opinion of such counsel,
restrictions are necessary in order to avoid the Partnership being treated as a
"publicly traded partnership" under Section 7704 of the Code.

8.06 CALL RIGHT.

         (a) Subject to Section 8.06(c) below, and subject to the modification
of any rights or obligations provided for herein by agreement(s) between the
General Partner and any one or more Limited Partners with respect to the
Partnership Units held by them, at any time after the expiration of the Holding
Period for the Partnership Units in question, the General Partner shall have the
right (the "CALL RIGHT") to purchase all of the Partnership Units held by a
Limited Partner at a price equal to the Cash Amount; provided, however, that the
General Partner may, in its sole and absolute discretion, elect to purchase such
Partnership Units by paying to the Partner in question the REIT Shares Amount in
lieu of the Cash Amount. The Call Right shall be exercised pursuant to a Call
Notice delivered by the General Partner to any such Limited Partner. The General
Partner may not exercise the Call Right for less than the entire interest of a
Limited Partner in the Partnership. A Limited Partner receiving the Call Notice
described above shall have no rights with respect to any interest in the
Partnership other than the right to receive payment for its interest in the
Partnership in cash or REIT Shares in accordance with this Section 8.06. An
assignee of a Limited Partner shall be bound by and subject to the Call Right of
the General Partner pursuant to this Section 8.06. In connection with any
exercise of such Call Right by the General Partner with respect to an assignee,
the Cash Amount (or REIT Shares Amount) shall be paid by the General Partner
directly to such assignee and not to the Limited Partner from which such
assignee acquired its Partnership Units. The General Partner shall be unable to
exercise the Call Right and the Call Right shall lapse upon the occurrence of a
Liquidating Event unless and until the Partners shall continue the business of
the Partnership under Section 7.03 hereof.

         (b) (i) Within 30 days after the delivery of the Call Notice by the
General Partner to a Limited Partner under this Section 8.06, the General
Partner (subject to the limitations set forth in Section 8.06(c)) shall transfer
and deliver the Cash Amount (or the REIT Shares Amount) to such Limited Partner
or, as applicable, its assignee, whereupon the General Partner (or its designee)
shall acquire the Partnership Units of such Limited Partner or, as applicable,
its assignee, and shall be treated for all purposes of this Agreement as the
owner of such Partnership Units (and as a Limited Partner with respect to such
Partnership Units).

                  (ii) In the event that the General Partner elects to pay such
         Limited Partner in the form of the REIT Shares Amount and such REIT
         Shares Amount is not a whole number of REIT Shares, the Limited Partner
         shall be paid (A) the number of REIT Shares which equals the nearest
         whole number less than such amount plus (B) an amount of cash which the
         General Partner determines, in its reasonable discretion, to represent
         the fair value of the remaining fractional REIT Share which would
         otherwise be payable to the Limited Partner.

                                      -36-
<PAGE>

                  (iii) Each Limited Partner agrees to deliver to the General
         Partner the Partnership Unit Certificate(s) representing its Limited
         Partnership Interest and to execute such documents as the General
         Partner may reasonably require in connection with the issuance of REIT
         Shares upon exercise of the Call Right (including without limitation an
         assignment of Partnership Units pursuant to the terms of which such
         Limited Partner (A) represents, warrants and certifies that it has
         marketable and unencumbered title to its Partnership Units, free and
         clear of the rights of or interest of any other person or entity, that
         it has the full right, power and authority to transfer and surrender
         its Partnership Units, and that it has obtained the consent or approval
         of all persons or entities, if any, having the right to consent to or
         approve of such transfer and surrender, and (B) agrees to indemnify and
         hold the General Partner harmless from and against any and all
         liabilities, charges, costs and expenses relating to such Limited
         Partner's Partnership Units which are subject to the Call Right or the
         exercise of the Call Right).

         (c) Notwithstanding the provisions of Sections 8.06(a) and 8.06(b)
above, the General Partner shall not be entitled to exercise the Call Right if
(i) a Liquidating Event has occurred with regard to the Partnership and the
Partnership has not been continued under Section 7.03 hereof; or (ii) the
delivery of REIT Shares to the Limited Partner (A) would be prohibited under the
Articles of Incorporation, (B) would adversely affect the ability of the General
Partner to continue to qualify as a REIT or subject the General Partner to any
additional taxes under Section 857 or Section 4981 of the Code, or (C) would be
prohibited under applicable federal or state securities laws or regulations.

         (d) Each Limited Partner covenants and agrees with the General Partner
that all Partnership Units delivered in connection with the Call Right shall be
delivered to the General Partner free and clear of all liens and encumbrances
and, notwithstanding anything contained herein to the contrary, the General
Partner shall not be under any obligation to acquire a Limited Partner's
Partnership Units (i) to the extent that any such Partnership Units are subject
to any such liens or encumbrances or (ii) in the event that the Limited Partner
shall fail to give the General Partner adequate assurances that such Partnership
Units are not subject to any such liens or encumbrances or shall fail to agree
to fully indemnify the General Partner from any such liens or encumbrances as
well as the liabilities, charges, costs and expenses referenced in the last
section of Section 8.06(b)(iii). Each Limited Partner further agrees that, in
the event any state or local transfer tax is payable as a result of the transfer
of its Partnership Units to the General Partner, such Limited Partner shall
assume and pay such transfer tax.

8.07 DUTIES AND CONFLICTS. The General Partner recognizes that the Limited
Partners and their Affiliates have or may have other business interests,
activities and investments, some of which may be in conflict or competition with
the business of the Partnership, and that such Persons are entitled to carry on
such other business interests, activities and investments. The Limited Partners
and their Affiliates may engage in or possess an interest in any other business
or venture of any kind, independently or with others, on their own behalf or on
behalf of other entities with which they are affiliated or associated, and such
Persons may engage in any activities, whether or not competitive with the
Partnership, without any obligation to offer any interest in such activities to
the Partnership or to any Partner. Neither the Partnership nor any Partner shall
have any right, by virtue of this Agreement, in or to such activities, or the
income or

                                      -37-
<PAGE>

profits derived therefrom, and the pursuit of such activities, even if
competitive with the business of the Partnership, and such activities shall not
be deemed wrongful or improper.

                                   ARTICLE IX

                   TRANSFERS OF LIMITED PARTNERSHIP INTERESTS

9.01 PURCHASE FOR INVESTMENT.

         (a) Each Limited Partner hereby represents and warrants to the General
Partner and to the Partnership that the acquisition of its Partnership Interest
is made as a principal for its account for investment purposes only and not with
a view to the resale or distribution of such Partnership Interest.

         (b) Each Limited Partner agrees that it will not sell, assign or
otherwise transfer its Partnership Interest or any fraction thereof, whether
voluntarily or by operation of law or at judicial sale or otherwise, to any
Person who does not make the representations and warranties to the General
Partner set forth in Section 9.01(a) above.

9.02 RESTRICTIONS ON TRANSFER OF LIMITED PARTNERSHIP INTERESTS.

         (a) Subject to the provisions of Sections 9.02(b), 9.02(c) and 9.02(d),
no Limited Partner may offer, sell, assign, hypothecate, pledge or otherwise
transfer all or any portion of its Limited Partnership Interest, or any of such
Limited Partner's economic rights as a Limited Partner, whether voluntarily or
by operation of law or at judicial sale or otherwise (collectively, a
"TRANSFER"), without the consent of the General Partner, which consent may be
granted or withheld in its sole and absolute discretion. Any such purported
transfer undertaken without such consent shall be considered to be null and void
ab initio and shall not be given effect. The Original Limited Partner
acknowledges that the General Partner has agreed not to grant its consent with
respect to any Transfer by the Original Limited Partner prior to the Transfer
Restriction Date; provided, that the Original Limited Partner shall not be
prohibited from a Transfer of its Partnership Interest pursuant to the exercise
of its right to exchange its Partnership Interest for REIT Shares pursuant to
Section 8.05 above, in which case the Original Limited Partner acknowledges that
the General Partner has also agreed not to grant its consent with respect to any
Transfer of said REIT Shares prior to the Transfer Restriction Date. The General
Partner may require, as a condition of any Transfer to which it consents, that
the transferor assume all costs incurred by the Partnership in connection
therewith.

         (b) No Limited Partner may withdraw from the Partnership other than as
a result of: (i) a permitted Transfer (i.e., a Transfer consented to as
contemplated by paragraph (a) above or paragraph (c) below or a Transfer made
pursuant to Section 9.05 below) of all of its Partnership Units pursuant to this
Article IX pursuant to an exchange of all of its Partnership Units pursuant to
Section 8.05 above; or (iii) a Transfer made pursuant to the sale of all its
Partnership Units pursuant to Section 8.06 above. Upon the permitted Transfer or
redemption of all of a Limited Partner's Partnership Units, such Limited Partner
shall cease to be a Limited Partner.

         (c) Subject to Sections 9.02(d), 9.02(e) and 9.02(f), a Limited Partner
may Transfer, with the consent of the General Partner, all or a portion of its
Partnership Units to (i) a parent or

                                      -38-
<PAGE>

parent's spouse, natural or adopted descendants, a spouse of any such
descendant, a brother or sister, or a trust created by such Limited Partner for
the benefit of such Limited Partner and/or any such person(s), for which trust
such Limited Partner or any such person(s) is a trustee, (ii) a corporation
controlled by a Person or Persons named in (i) above, or (iii) if the Limited
Partner is an entity, its beneficial owners.

         (d) No Limited Partner may effect a Transfer of its Limited Partnership
Interest, in whole or in part, if, in the opinion of legal counsel for the
Partnership, such proposed Transfer would require the registration of the
Limited Partnership Interest under the Securities Act, or would otherwise
violate any applicable federal or state securities or blue sky law (including
investment suitability standards).

         (e) No Transfer by a Limited Partner of its Partnership Units, in whole
or in part, may be made to any Person if (i) in the opinion of legal counsel for
the Partnership, the transfer would result in the Partnership's being treated as
an association taxable as a corporation (other than a qualified REIT subsidiary
within the meaning of Section 856(i) of the Code), (ii) in the opinion of legal
counsel for the Partnership, it would adversely affect the ability of the
General Partner to continue to qualify as a REIT or subject the General Partner
to any additional taxes under Section 857 or Section 4981 of the Code, or (iii)
such transfer is effectuated through an "established securities market" or a
"secondary market" (or the substantial equivalent thereof) within the meaning of
Section 7704 of the Code.

         (f) No transfer of any Partnership Units may be made to a lender to the
Partnership or any Person who is related (within the meaning of Regulations
Section 1.752-4(b)) to any lender to the Partnership whose loan constitutes a
nonrecourse liability (within the meaning of Regulations Section 1.752-1(a)(2)),
without the consent of the General Partner, which may be withheld in its sole
and absolute discretion; provided, that as a condition to such consent the
lender will be required to enter into an arrangement with the Partnership and
the General Partner to exchange or redeem for the Cash Amount any Partnership
Units in which a security interest is held simultaneously with the time at which
such lender would be deemed to be a partner in the Partnership for purposes of
allocating liabilities to such lender under Section 752 of the Code.

         (g) Any Transfer in contravention of any of the provisions of this
Article IX shall be void and ineffectual and shall not be binding upon, or
recognized by, the Partnership.

         (h) Prior to the consummation of any Transfer under this Article IX,
the transferor and/or the transferee shall deliver to the General Partner such
opinions, certificates and other documents as the General Partner shall request
in connection with such Transfer.

9.03 ADMISSION OF SUBSTITUTE LIMITED PARTNER.

         (a) Subject to the other provisions of this Article IX, an assignee of
the Limited Partnership Interest of a Limited Partner (which shall be understood
to include any purchaser, transferee, donee or other recipient of any
disposition of such Limited Partnership Interest) shall be deemed admitted as a
Limited Partner of the Partnership only with the consent of the General Partner
and upon the satisfactory completion of the following:

         consent of the General Partner to its admission as a Substitute Limited
         Partner, which consent may be given or denied in the exercise of the
         General Partner's sole and absolute discretion.

         (b) For the purpose of allocating Profit and Loss and distributing cash
received by the Partnership, a Substitute Limited Partner shall be treated as

upon the filing of the Certificate described in Section 9.03(a)(ii) hereof or,

9.04 RIGHTS OF ASSIGNEES OF PARTNERSHIP INTERESTS.

         (a) Subject to the provisions of Sections 9.01 and 9.02 hereof, except

                                      -40-
<PAGE>

         (b) Any Person who is the assignee of all or any portion of a Limited
Partner's Limited Partnership Interest, but who does not become a Substitute
Limited Partner and desires to make a further assignment of such Limited
Partnership Interest, shall be subject to all the provisions of this Article IX
to the same extent and in the same manner as any Limited Partner desiring to
make an assignment of its Limited Partnership Interest.

9.05 EFFECT OF BANKRUPTCY, DEATH, INCOMPETENCE OR TERMINATION OF A LIMITED
PARTNER. The occurrence of an Event of Bankruptcy as to a Limited Partner, the
death of a Limited Partner or a final adjudication that a Limited Partner is
incompetent (which term shall include, but not be limited to, insanity) shall
not cause the termination or dissolution of the Partnership, and the business of
the Partnership shall continue if an order for relief in a bankruptcy proceeding
is entered against a Limited Partner, the trustee or receiver of his estate or,
if he dies, his executor, administrator or trustee, or, if he is finally
adjudicated incompetent, his committee, guardian or conservator, and any such
Person shall have the rights of such Limited Partner for the purpose of settling
or managing his estate property and such power as the bankrupt, deceased or
incompetent Limited Partner possessed to assign all or any part of his
Partnership Interest and to join with the assignee in satisfying conditions
precedent to the admission of the assignee as a Substitute Limited Partner.

9.06 JOINT OWNERSHIP OF INTERESTS. A Partnership Interest may be acquired by two
individuals as joint tenants with right of survivorship, provided, that such
individuals either are married or are related and share the same personal
residence. The written consent or vote of both owners of any such jointly-held
Partnership Interest shall be required to constitute the action of the owners of
such Partnership Interest; provided, however, that the written consent of only
one joint owner will be required if the Partnership has been provided with
evidence satisfactory to the counsel for the Partnership that the actions of a
single joint owner can bind both owners under the applicable laws of the state
of residence of such joint owners. Upon the death of one owner of a Partnership
Interest held in a joint tenancy with a right of survivorship, the Partnership
Interest shall become owned solely by the survivor as a Limited Partner and not
as an assignee. The Partnership need not recognize the death of one of the
owners of a jointly held Partnership Interest until it shall have received
notice of such death. Upon notice to the General Partner from either owner, the
General Partner shall cause the Partnership Interest to be divided into two
equal Partnership Interests, which shall thereafter be owned separately by each
of the former joint owners.

                                      -43-
<PAGE>

         (d) any amendment that would impose on the Limited Partners any
obligation to make additional Capital Contributions to the Partnership.

         The foregoing notwithstanding, the approval of any amendment to this
Agreement that shall be part of a plan of merger, plan of exchange or plan of
conversion involving the Partnership or the Partnership Interests shall be
governed by Article XII.

11.02 MEETINGS OF PARTNERS.

         (a) The Partners may but shall not be required to hold any annual,
periodic or other formal meetings. Meetings of the Partners may be called by the
General Partner or by any Limited Partner or Limited Partners holding at least
10% of the Partnership Units in the Partnership.

         (b) The Partner or Partners calling the meeting may designate any place
within the State of Texas as the place of meeting for any meeting of the
Partners; and Partners holding at least a majority of the Partnership Units in
the Partnership may designate any place outside the State of Texas as the place
of meeting for any meeting of the Partners. If no designation is made, or if a
special meeting is called, the place of meeting shall be the principal place of
business of the Partnership.

         (c) Except as provided in Section 11.02(d), written notice stating the
place, day and hour of the meeting and the purpose or purposes for which the
meeting is called shall be delivered not less than ten (10) nor more than ninety
(90) days before the date of the meeting, either personally or by mail, by or at
the direction of the Partner or Partners calling the meeting, to each Partner
entitled to vote at such meeting and to each Partner not entitled to vote who is
entitled to notice of the meeting.

         (d) Anything in this Agreement to the contrary notwithstanding, with
respect to any meeting of the Partners, any Partner who in person or by proxy
shall have waived in writing notice of the meeting, either before or after such
meeting, or who shall attend the meeting in person or by proxy, shall be deemed
to have waived notice of such meeting unless such Partner attends for the
express purpose of objecting, at the beginning of the meeting, and does so
object to the transaction of any business because the meeting is not lawfully
called or convened.

         (e) If all of the Partners shall meet at any time and place, either
within or outside of the State of Texas, in person or by proxy, and consent to
the holding of a meeting at such time and place, such meeting shall be valid
without call or notice, and at such meeting lawful action may be taken.

         (f) For the purpose of determining Partners entitled to notice of or to
vote at any meeting of Partners or any adjournment thereof, the date on which
notice of the meeting is mailed shall be the record date. When a determination
of Partners entitled to vote at any meeting of Partners has been made as
provided in this Section, such determination shall apply to any adjournment
thereof.

         (g) Partners holding at least a majority of the Partnership Units
entitled to vote at a meeting, represented in person or by proxy, shall
constitute a quorum at any meeting of Partners.

                                      -44-
<PAGE>

In the absence of a quorum at any such meeting, Partners holding at least a
majority of Partnership Units so represented may adjourn the meeting to another
time and place. Any business which might have been transacted at the original
meeting may be transacted at any adjourned meeting at which a quorum is present.
No notice of an adjourned meeting need be given if the time and place are
announced at the meeting at which the adjournment is taken unless the
adjournment is for more than 120 days. The Partners present at a duly organized
meeting may continue to transact business until adjournment, notwithstanding the
withdrawal during such meeting of that number Partnership Units whose absence
would cause less than a quorum to be present.

         (h) If a quorum is present, the affirmative vote of Partners holding a
majority of the Partnership Units entitled to vote, present in person or
represented by proxy, shall be binding on all Partners, unless the vote of a
greater or lesser proportion or number of Partnership Units or Partners is
otherwise required by applicable law or by this Agreement. Unless otherwise
expressly provided herein or required under applicable law, Partners who have an
interest (economic or otherwise) in the outcome of any particular matter upon
which the Partners' vote or consent is required may vote or consent upon any
such matter and their Partnership Units, vote or consent, as the case may be,
shall be counted in the determination of whether the requisite matter was
approved by the Partners.

         (i) At all meetings of Partners, a Partner may vote in person or by
proxy executed in writing by the Partner or by the Partner's duly authorized
attorney-in-fact. Such proxy shall be filed with the General Partner before or
at the time of the meeting. No proxy shall be valid after eleven months from the
date of its execution, unless otherwise provided in the proxy.

         (j) Action required or permitted to be taken at a meeting of Partners
may be taken without a meeting if the action is evidenced by one or more written
consents or approvals describing the action taken and signed by sufficient
Partners or Partners holding sufficient Partnership Units, as the case may be,
to approve such action had such action been properly voted on at a duly called
meeting of the Partners. Action taken under this Section 11.02(j) is effective
when the requisite Partners or Partners with the requisite Partnership Units, as
the case may be, have signed the consent or approval, unless the consent
specifies a different effective date.

                                   ARTICLE XII

exchange, or plan of conversion shall otherwise comply with the requirements of
this Agreement and the Act.

         (b) Any merger pursuant to a plan of merger described in Section
12.01(a)(i) hereof shall be conditioned upon the merger being permitted by the
laws under which each other entity that is a party to the merger is incorporated
or organized or by the constituent documents of such other entity that are not
inconsistent with such laws. Any exchange pursuant to a plan of exchange
described in Section 12.01(a)(ii) hereof shall be conditioned upon the issuance
of shares or other interests of the acquiring foreign limited partnership or
other entity being permitted by the laws under which such foreign limited
partnership or other entity is incorporated or organized or is not inconsistent
with such laws. Any conversion pursuant to a plan of conversion described in
Section 12.01(a)(iii) hereof shall be conditioned upon such conversion being
permitted by, or not inconsistent with, the laws of the jurisdiction in which
the converted entity is to be incorporated, formed or organized and the
incorporation, formation or organization of the converted entity is effected in
compliance with such laws.

         (c) The Partnership may adopt a plan of merger, plan of exchange or
plan of conversion if the General Partner acts upon and the Limited Partners (if

         (a) Except as provided by Section 12.02(g) below, after acting on a

         that the plan of merger, plan of exchange or plan of conversion be
         approved by the Limited Partners, unless the General Partner determines
         that for any reason it should not make that recommendation, in which
         case the General Partner shall adopt a resolution directing that the
         plan of merger, plan of exchange or plan of conversion be submitted to
         the Limited Partners for approval without recommendation; and

                  (ii) the Limited Partners entitled to vote on the plan of
         merger, plan of exchange or plan of conversion must approve the plan.

         (c) The General Partner may condition its submission to the Limited
Partners of a plan of merger, plan of exchange or plan of conversion, and the

required for the approval of the plan of merger, plan of exchange or plan of
conversion.

                                      -46-

         (d) The General Partner shall notify each Limited Partner, whether or
not entitled to vote, of the meeting of the Limited Partners at which the plan

the purpose, or one of the purposes, of the meeting is to consider the plan of
merger, plan of exchange or plan of conversion and shall contain or be
accompanied by a copy or summary of the plan. Any such approval may be by
written consent of the requisite Limited Partners as would be required to
approve the plan at any meeting where all the Limited Partners are present.

         (e) Unless the General Partner (acting pursuant to Section 12.02(c))
requires a greater vote, the vote of the Limited Partners required for approval
of a plan of merger, plan of exchange or plan of conversion shall be the
affirmative vote of the holders of more than 50% of the Percentage Interests of
the Limited Partners entitled to vote thereon.

         (f) Unless applicable law otherwise requires (in which case the
approval of the Limited Partners shall continue to be required and the foregoing
provisions of this Section 12.02 shall continue to apply), (1) approval by the
Limited Partners on a plan of exchange shall not be required, and the foregoing
provisions of this Section 12.02 do not apply, if the Partnership is the
acquiring entity in the plan of exchange, and (2) approval by the Limited
Partners on a plan of merger or a plan of conversion shall not be required and

         entity;

                  (ii) the partnership agreement of the surviving or resulting
         limited partnership will not materially differ from this Agreement

         applicable law or other insignificant conforming differences;

                  (iii) Limited Partners who held Limited Partnership Interests
         immediately before the effective date of the merger or conversion will
         hold interests in the surviving or resulting entity in the same
         proportions, immediately after the effective date of the merger or
         conversion; and

                  (iv) the General Partner adopts a resolution approving the
         plan of merger or plan of conversion.

         (g) After a plan of merger, plan of exchange or plan of conversion is
approved, and at any time before the merger, exchange or conversion has become
effective, the plan of merger, plan of exchange or plan of conversion may be
abandoned (subject to any contractual rights by any of the entities that are a
party thereto), without action by the Limited Partners, in accordance with the
procedures set forth in the plan of merger, plan of exchange or plan of
conversion or, if no such procedures are set forth in the plan, in the manner
determined by the General Partner.

12.03 RIGHTS OF DISSENTING LIMITED PARTNERS.

         (a) In the absence of fraud in the transaction, the remedy provided by
this Section 12.03 to a Limited Partner voting against any merger, exchange or
conversion or objecting to a merger, exchange or conversion approved by the
written consent of Limited Partners (a "DISSENTING LIMITED PARTNER") is the
exclusive remedy for the recovery of the value of his Limited Partnership
interests or money damages with respect to the transaction. If the existing,
surviving, or new corporation or limited partnership (foreign or domestic) or
other entity, as the case may be, complies with the requirements of this Section
12.03, any Dissenting Limited Partner who fails to comply with the requirements
of this Section 12.03 shall not be entitled to bring suit for the recovery of
the value of his Limited Partnership interests or money damages with respect to
the transaction. A "Dissenting Limited Partner" in respect of any merger,
exchange or conversion shall expressly exclude any Limited Partner who votes in
favor of the related plan of merger, plan of exchange or plan of conversion or
who abstains or fails to timely vote therefor. In the event of a plan of merger,
plan of exchange or plan of conversion approved by written consent, a
"Dissenting Limited Partner" in respect of any related merger, exchange or
conversion shall expressly exclude Limited Partners who provide such written
consent and Limited Partners who fail to object to the merger, exchange or
conversion and demands payment for such Limited Partner's Limited Partnership
Interest in writing to the General Partner within twenty (20) days after notice
to the Limited Partners of the receipt by the Partnership of written consents
sufficient to approve such merger, exchange or conversion. All such Limited
Partners who are not included within the definition of Dissenting Limited
Partner in respect of any merger, exchange or conversion shall participate in
the merger, exchange or conversion according to the approved plan of merger,
plan of exchange or plan of conversion.

         (b) Any Dissenting Limited Partner who has opted for payment for his
Limited Partnership interests shall not thereafter be entitled to vote or
exercise any other rights of a Limited Partner except the right to receive
payment for his Limited Partnership interests and the right to maintain an
appropriate action to obtain relief on the ground that the transaction would be
or was fraudulent. Limited Partnership Interests of Dissenting Limited Partners
for which payment has been made shall not thereafter be considered outstanding
for the purposes of any subsequent vote of the Limited Partners.

         (c) Within twenty (20) days after a Dissenting Limited Partner votes
against any plan of merger, plan of exchange or plan of conversion which is
approved by a vote of the Limited Partners, or in connection with a Limited
Partner's objection to any plan of merger, plan of exchange or plan of
conversion approved by the written consent of the Limited Partners, the
Dissenting Limited Partner may demand by written notice to the General Partner
that payment for his Limited Partnership Interest be made. Upon receipt of such
a payment demand, the General Partner shall (i) make a notation on the records
of the Partnership that such demand has been made and (ii) within a reasonable
period of time after the later of the receipt of a payment demand or the
consummation of the merger, exchange or conversion, cause the Partnership to pay
to the Dissenting Limited Partner the fair value of such Dissenting Limited
Partner's Partnership Interest without interest. The fair value of a Dissenting
Limited Partner's Partnership Interest shall be an amount equal to the
Dissenting Limited Partner's pro rata share (as would be determined under
Section 5.06 hereof if the Partnership were liquidating) of the appraised value
of the net assets of the Partnership based on an appraisal of all assets of the
Partnership from a Competent Independent Expert. The assets of the Partnership
shall be appraised on a consistent basis. The appraisal shall be based on an
evaluation of all relevant

                                      -48-
<PAGE>

information and shall include the current value of the Partnership's assets as
of the date immediately prior to the proposed merger, exchange or conversion.
The appraisal shall assume an orderly liquidation of the Partnership's assets
over a twelve (12) month period, shall consider other balance sheet items, and
shall be net of the assumed cost of sale. The terms of the engagement of the
appraiser shall clearly state that the engagement is for the benefit of the
Partnership and its Limited Partners. A summary of the independent appraisal,
including all material assumptions underlying the appraisal, shall be provided
to Dissenting Limited Partners in connection with the payment of the fair value
of their Limited Partnership Interests.

         (d) If a Dissenting Limited Partner shall fail to make a payment demand

of merger, plan of exchange or plan of conversion approved by written consent of
the Limited Partners, shall fail to provide notice of dissent within the period
set forth in Section 12.03(a) hereof, such Dissenting Limited Partner and all
persons claiming under him shall be conclusively presumed to have approved and
ratified the merger, conversion or exchange and shall be bound thereby, the
right of such Dissenting Limited Partner to be paid the fair value of his
Limited Partnership Interest shall cease, and his status as a Limited Partner
shall be restored without prejudice to any proceedings which may have been taken
during the interim, and such Dissenting Limited Partner shall be entitled to

Agreement, all claims, disputes and controversies between the parties hereto
(including, without limitation, any claims, disputes and controversies between
the Partnership and any one or more of the Partners and between or among any
Partners) arising out of or in connection with this Agreement or the Partnership
created hereby, or any act or failure to act by the General Partner or any other
Partner hereunder, shall be resolved by binding arbitration in Dallas, Texas by
the American Arbitration Association (the "AAA"), in accordance with this
Section 13.10. Any arbitration called for by this Section 13.10 shall be
conducted in accordance with the following procedures:

         (a) The Partnership or any Partner (the "REQUESTING PARTY") may demand
arbitration pursuant to this Section 13.10 at any time by giving written notice
of such demand (the "DEMAND NOTICE") to all other Partners and (if the
Requesting Party is not the Partnership) to the Partnership which Demand Notice
shall describe in reasonable detail the nature of the claim, dispute or
controversy.

         (b) Within 15 days after the giving of a Demand Notice or such
additional time as required by the AAA, the AAA shall select and designate in
writing three reputable, disinterested individuals willing to act as an
arbitrator of the claim, dispute or controversy in question.

         (c) The presentations of the parties hereto in the arbitration
proceeding shall be commenced and completed within sixty (60) days after the
selection of the arbitration panel pursuant to subsection B above, and the
arbitration panel shall render its decision (and specify in reasonable detail
its reasons therefor) in writing within thirty (30) days after the completion of
such presentations. Any decision concurred in by any two (2) of the arbitrators
shall constitute the decision of the arbitration panel, and unanimity shall not
be required.

         (d) The arbitration panel shall include in its decision a direction
that all of the attorneys' fees and costs of any party or parties and the costs
of such arbitration be paid by the

                                      -50-
<PAGE>

losing party or parties in the arbitration. On the application of a party before
or after the initial decision of the arbitration panel, and proof of its
attorneys' fees and costs, the arbitration panel shall order the other party to
make any payments directed pursuant to the preceding sentence.

         Any decision rendered by the arbitration panel in accordance herewith
shall be final and binding on the parties hereto, and judgment thereon may be
entered by any state or federal court of competent jurisdiction. Arbitration
shall be the exclusive method available for resolution of claims, disputes and
controversies arising between and among the parties relating to this Agreement
and the conduct of the parties hereto in relation to Partnership matters, and
the Partnership and its Partners stipulate that the provisions hereof shall be a
complete defense to any suit, action or proceeding in any court or before any
administrative or arbitration tribunal with respect to any such claim,
controversy or dispute. The provisions of this Section 13.10 shall survive the
dissolution of the Partnership.

         Nothing contained herein shall be deemed to give the arbitrators any
authority, power or right to alter, change, amend, modify, add to, or subtract
from any of the provisions of this Agreement.

13.11 VOTE OF AFFILIATED LIMITED PARTNERS. Notwithstanding any provision to the
contrary set forth in this Agreement, in each instance in which the consent,
approval or vote of Limited Partners is required hereunder, any Partnership
Interest held as a Limited Partner by any Affiliate of the Sponsor shall not be
included for purposes of calculating whether the requisite approval of Partners
is obtained unless, as of the date of determination, there are no Limited
Partners entitled to vote or consent who are not Affiliates of the Sponsor.

13.12 ACKNOWLEDGEMENT AS TO EXCULPATION AND INDEMNIFICATION.

         THE PARTIES HERETO ACKNOWLEDGE AND AGREE THAT THIS AGREEMENT CONTAINS
EXCULPATION AND INDEMNIFICATION IN RESPECT OF THE ACTIONS OR OMISSIONS OF THE
GENERAL PARTNER AND DIRECTORS, OFFICERS AND AFFILIATES OF THE GENERAL PARTNER BY
THE PARTNERSHIP EVEN IF SUCH ACTIONS OR OMISSIONS CONSTITUTE NEGLIGENCE OF SUCH
PERSONS.
