Performance Partner, multiplied by the excess of (i) the Capital Account per

Partner has no special arrangements with the Partnership, other than as set
forth in this Agreement, which would cause its Capital Account per Partnership
Unit to be different from the Capital Account per Partnership Unit of other
Limited Partners who are not Performance Partners or PLPs. If the Partner
described in (ii) above does not exist, the amount used for purposes of (ii)

(10) consecutive trading days immediately preceding the date with respect to
which "Fair Market Value" must be determined hereunder or, if such date is not a
Business Day, the immediately preceding Business Day. The market price for each
such trading day shall be (i) if such shares are listed or admitted to trading
on any securities exchange or the Nasdaq National Market, the closing price,
regular way, on such day, or if no such sale takes place on such day, the
average of the closing bid and asked prices on such day, (ii) if such shares are
not listed or admitted to trading on any securities exchange or the Nasdaq
National Market, the last reported sale price on such day or, if no sale takes
place on such day, the average of the closing bid and asked prices on such day,
as reported by a reliable quotation source designated by the General Partner or
(iii) if such shares are not listed or admitted to trading on any securities
exchange or the Nasdaq National Market and no such last reported sale price or
closing bid and asked prices are available, the average of the reported high bid
and low asked prices on such day, as reported by a reliable quotation source
designated by the General Partner, or if there shall be no bid and asked prices
on such day, the

                                       7

<PAGE>   12
average of the high bid and low asked prices, as so reported, on the most recent
day (not more than ten (10) days prior to the date in question) for which prices
have been so reported; provided, that if there are no bid and asked prices
reported during the ten (10) days prior to the date in question, the Fair Market
Value of such shares shall be determined by the General Partner acting in good
faith on the basis of such quotations and other information as it considers, in
its reasonable judgment, appropriate. In the event the REIT Shares Amount for
such shares includes rights that a holder of such shares would be entitled to
receive, then the Fair Market Value of such rights shall be determined by the
General Partner acting in good faith on the basis of such quotations and other
information as it considers, in its reasonable judgment, appropriate; provided,
that in connection with determining the Deemed Value of the Partnership
Interests for purposes of determining the number of additional Partnership Units
issuable upon a Capital Contribution funded by an underwritten public offering
of shares of capital stock of the General Partner, the Fair Market Value of such
shares shall be the public offering price per share of such class of capital

                        Liquidator, to make, evidence, give, confirm or ratify
                        any vote, consent, approval, agreement or other action
                        which is made or given by the Partners hereunder or is
                        consistent with the terms of this Agreement or

                        terms or intent of this Agreement.

Nothing contained herein shall be construed as authorizing the General Partner
or any Liquidator to amend this Agreement except in accordance with Article 14
or as may be otherwise expressly provided for in this Agreement.

               B. The foregoing power of attorney is hereby declared to be
irrevocable and a power coupled with an interest, in recognition of the fact
that each of the Partners will be relying upon the power of the General Partner
and any Liquidator to act as contemplated by this Agreement in any filing or
other action by it on behalf of the Partnership, and it shall survive and not be
affected by the subsequent Incapacity of any Limited Partner or Assignee and the
transfer of all or any portion of such Limited Partner's or Assignee's
Partnership Units and shall extend to such Limited Partner's or Assignee's
heirs, successors, assigns and personal representatives. Each such Limited
Partner or Assignee hereby agrees to be bound by any representation made by the
General Partner or any Liquidator, acting in good faith pursuant to such power
of attorney; and each such Limited Partner or Assignee hereby waives any and all
defenses which may be available to contest, negate or disaffirm the action of
the General Partner or any Liquidator, taken

                                       20

<PAGE>   25
in good faith under such power of attorney. Each Limited Partner or Assignee
shall execute and deliver to the General Partner or any Liquidator, within
fifteen (15) days after receipt of the General Partner's or Liquidator's request
therefor, such further designation, powers of attorney and other instruments as
the General Partner or the Liquidator, as the case may be, deems necessary to
effectuate this Agreement and the purposes of the Partnership.

               Without the consent of the General Partner which may be given or
withheld in its sole discretion, the Partnership shall not at any time have more
than one hundred (100) partners (including as partners those persons indirectly
owning an interest in the Partnership through a partnership, limited liability
company, S corporation or grantor trust (such entity, a "flow through entity"),
but only if substantially all of the value of such person's interest in the flow
through entity is attributable to the flow through entity's interest (direct or
indirect) in the Partnership).

                                     PURPOSE

               Section 3.1 Purpose and Business

               The purpose and nature of the business to be conducted by the
Partnership is (i) to conduct any business that may be lawfully conducted by a
limited partnership organized pursuant to the Act; provided, however, that such
business shall be limited to and conducted in such a manner as to permit the
General Partner at all times to be classified as a REIT for Federal income tax
purposes, unless the General Partner ceases to qualify as a REIT for reasons
other than the conduct of the business of the Partnership, (ii) to enter into
any partnership, joint venture or other similar arrangement to engage in any of
the foregoing or to own interests in any entity engaged, directly or indirectly,
in any of the foregoing and (iii) to do anything necessary or incidental to the
foregoing. In connection with the foregoing, and without limiting the General
Partner's right in its sole discretion to cease qualifying as a REIT, the
Partners acknowledge that the General Partner's current status as a REIT inures
to the benefit of all the Partners and not solely the General Partner.

               Section 3.2 Powers

               The Partnership is empowered to do any and all acts and things
necessary, appropriate, proper, advisable, incidental to or convenient for the

limitation, full power and authority, directly or through its ownership interest
in other entities, to enter into, perform and carry out contracts of any kind,

mortgage, deed of trust, pledge or other lien, acquire and develop real
property, and manage, lease, sell, transfer and dispose of real property;
provided, however, not withstanding anything to the contrary in this Agreement,
the Partnership shall not take, or refrain from taking, any action which, in the
judgment of the General Partner, in its sole and absolute discretion, (i) could
adversely affect the ability of the General Partner to continue to qualify as a
REIT, (ii) absent the consent of the General Partner, which may be given or
withheld in its sole and absolute discretion, and except with respect to the
distribution of Available Cash to the Series B Limited Partners in accordance
with Section 17.3, could subject the General Partner to any taxes under Section
857 or Section 4981 of the Code, or (iii) could violate any law or regulation of
any governmental body or agency having jurisdiction over the General Partner or
its securities, unless any such action (or inaction) under the foregoing clauses
(i), (ii) or (iii) shall have been specifically consented to by the General
Partner in writing.

               Section 3.3 Partnership Only for Purposes Specified

               The Partnership shall be a partnership only for the purposes
specified in Section 3.1, and this Agreement shall not be deemed to create a
partnership among the Partners with respect to any activities whatsoever other
than the activities within the purposes of the Partnership as specified in
Section 3.1. Except as otherwise provided in this Agreement, no Partner shall
have any authority to act for, bind, commit or assume any obligation or
responsibility on behalf of the Partnership, its properties or any other
Partner. No Partner, in its capacity as a Partner under this Agreement, shall be
responsible or liable for any indebtedness or obligation of another Partner, nor
shall the Partnership be responsible or liable for any indebtedness or
obligation of any Partner, incurred either before or after the execution and
delivery of this Agreement by such Partner, except as to those responsibilities,
liabilities, indebtedness or obligations incurred pursuant to and as limited by
the terms of this Agreement and the Act.

other law to which such Partner is subject, (iii) such Partner is neither a
"foreign person" within the meaning of Section 1445(f) of the Code nor a

including without limitation, that of its general partner(s), committee(s),

the resale or distribution of all or any part thereof, nor with a view toward
selling or otherwise distributing such interest or any part thereof at any
particular time or under any predetermined circumstances. Each Partner further
represents and warrants that it is a sophisticated investor, able and accustomed
to handling sophisticated financial matters for itself, particularly real estate
investments, and that it has a sufficiently high net worth that it does not
anticipate a need for the funds it has invested in the Partnership in what it
understands to be a highly speculative and illiquid investment.

               D. Each Partner further represents, warrants and agrees as
follows:

                      (i) Except as provided in Exhibit E, at any time such
        Partner actually or Constructively owns a 25% or greater capital
        interest or profits interest in the Partnership, it does not and will

        interest or profits interest in the Partnership, it does not, and agrees
        that it will not without the prior written consent of the General
        Partner, actually own or Constructively Own, any stock in the General
        Partner, other than any REIT Shares or other shares of capital stock of
        the General Partner such Partner may acquire (a) as a result of an
        exchange of Tendered Units pursuant to Section 8.6 or (b) upon the
        exercise of options granted or delivery of REIT Shares pursuant to any
        Stock Incentive Plan, in each case subject to the ownership limitations
        set forth in the General Partner's Charter.

                      (iii) Upon request of the General Partner, it will
        disclose to the General Partner the amount of REIT Shares or other

        Partners may become non-exercisable, and (y) some or all of such shares
        owned by the Partners and/or some or all of the Partnership Interests
        owned by the Limited Partners may be automatically transferred to a

Properties and any other assets of the Partnership so that the Partnership will
be a "real estate operating company" (as such term is defined in the Plan Asset
Regulation).

               Subject to Section 4.3, the Partnership may incur Debt, or enter
into other similar credit, guarantee, financing or refinancing arrangements for
any purpose (including, without limitation, in connection with any further
acquisition of Properties) with any Person that is not the General Partner upon
such terms as the General Partner determines appropriate; provided, that the
Partnership shall not incur any Debt that is recourse to the General Partner,
except to the extent otherwise agreed to by the General Partner in its sole
discretion.

               Section 4.3 Additional Funding and Capital Contributions

               A. General. The General Partner may, at any time and from time to
time, determine that the Partnership requires additional funds ("Additional
Funds") for the acquisition of additional Properties or for such other
Partnership purposes as the General Partner may determine. Additional Funds may
be raised by the Partnership, at the election of the General Partner, in any
manner provided in, and in accordance with, the terms of this Section 4.3. No
Person shall have any preemptive, preferential or similar right or rights to
subscribe for or acquire any Partnership Interest, except as set forth in this
Section 4.3.

               B. General Partner Loans. The General Partner may enter into a
Funding Debt, including, without limitation, Funding Debt that is convertible
into REIT Shares, and lend the Additional Funds to the Partnership (a "General
Partner Loan"); provided, however, that the General Partner shall not be
obligated to lend the net proceeds of any Funding Debt to the Partnership in a
manner that would be inconsistent with the General Partner's ability to remain
qualified as a REIT. If the General Partner enters into such a Funding Debt, the
General Partner Loan will consist of the net proceeds from such Funding Debt and
will be on comparable terms and conditions, including interest rate, repayment
schedule and costs and expenses, as shall be applicable with respect to or
incurred in connection with such Funding Debt.

               C. Issuance of Additional Partnership Interests. The General
Partner may raise all or any portion of the Additional Funds by accepting
additional Capital Contributions of cash. The General Partner may also accept
additional Capital Contributions of real property or other non-cash assets. In
connection with any such additional Capital Contributions (of cash or property),
and subject to Section 17.6 hereof, the General Partner is hereby authorized to
cause the Partnership from time to time to issue to Partners (including the
General Partner) or other Persons (including, without limitation, in connection
with the contribution of property to the Partnership) additional Partnership
Units or other Partnership Interests in one or more classes, or one or more
series of any of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers, and duties, including
rights, powers, and duties senior to then existing Limited Partnership
Interests, all as shall be determined by the General Partner in its sole and
absolute discretion subject to Delaware law, and as set forth by amendment to
this Agreement, including without limitation: (i) the allocations of items of
Partnership income, gain, loss, deduction, and credit to such class or series of
Partnership Interests; (ii) the right of each such class or series of
Partnership Interests to share in Partnership

                                       25

<PAGE>   30
distributions; (iii) the rights of each such class or series of Partnership
Interests upon dissolution and liquidation of the Partnership; and (iv) the
right to vote, including, without limitation, the limited partner approval
rights set forth in Section 11.2.A; provided, that no such additional
Partnership Units or other Partnership Interests shall be issued to the General
Partner unless either (a) the additional Partnership Interests are issued in
connection with the grant, award, or issuance of shares of the General Partner
pursuant to Section 4.3.D below, which shares have designations, preferences,
and other rights (except voting rights) such that the economic interests
attributable to such shares are substantially similar to the designations,
preferences and other rights of the additional Partnership Interests issued to
the General Partner in accordance with this Section 4.3.C or (b) the additional
Partnership Interests are issued to all Partners holding Partnership Interests
in the same class in proportion to their respective Percentage Interests in such
class. In the event that the Partnership issues additional Partnership Interests
pursuant to this Section 4.3.C, the General Partner shall make such revisions to
this Agreement (including but not limited to the revisions described in Sections
5.4, 6.2.C, and 8.6) as it determines are necessary to reflect the issuance of
such additional Partnership Interests.

               D. Issuance of REIT Shares or Other Securities by the General
Partner. The General Partner shall not issue any additional REIT Shares (other
than REIT Shares issued pursuant to Section 8.6 or pursuant to a dividend or
distribution (including any stock split) of REIT Shares to all of its
stockholders or all of its stockholders who hold a class of stock of the General
Partner), other shares of capital stock of the General Partner (other than in
connection with the acquisition of Partnership Interests in exchange for capital
stock of the General Partner which corresponds in ranking to the Partnership's
Partnership Interests being acquired) or New Securities unless the General
Partner shall make a Capital Contribution of the net proceeds (including,
without limitation, cash and Properties) from the issuance of such additional
REIT Shares, other shares of capital stock or New Securities, as the case may
be, and from the exercise of the rights contained in such additional New
Securities, as the case may be. The General Partner's Capital Account shall be
increased by the amount of cash or the value of Properties so contributed.

               E. Percentage Interest Adjustments in the Case of Capital
Contributions for Partnership Units. Upon the acceptance of additional Capital
Contributions in exchange for any class or series of Partnership Units, the
Percentage Interest related thereto shall be equal to a fraction, the numerator
of which is equal to the amount of cash and the Agreed Value of the Properties
contributed as of the Business Day immediately preceding the date on which the
additional Capital Contributions are made (an "Adjustment Date") and the
denominator of which is equal to the sum of (i) the Deemed Value of the
Partnership Interests of such class or series (computed as of the Business Day
immediately preceding the Adjustment Date) plus (ii) the aggregate amount of
cash and the Agreed Value of the Property contributed to the Partnership on such
Adjustment Date in respect of such class or series of Partnership Interests. The
Percentage Interest of each other Partner holding Partnership Interests of such
class or series not making a full pro rata Capital Contribution shall be
adjusted to equal a fraction, the numerator of which is equal to the sum of (i)
the Deemed Partnership Interest Value of such Limited Partner in respect of such
class or series (computed as of the Business Day immediately preceding the
Adjustment Date) plus (ii) the amount of cash and the Agreed Value of the
Property contributed by such Partner to the Partnership in respect of such class
or series as of such Adjustment Date, and the

                                       26

<PAGE>   31
denominator of which is equal to the sum of (a) the Deemed Value of the
Partnership Interests of such class (computed as of the Business Day immediately
preceding the Adjustment Date), plus (b) the aggregate amount of cash and the
Agreed Value of the Property contributed to the Partnership on such Adjustment
Date in respect of such class or series. Notwithstanding the foregoing, solely
for purposes of calculating a Partner's Percentage Interest pursuant to this
Section 4.3.E, (i) in the case of cash Capital Contributions by the General
Partner, such Capital Contributions will be deemed to equal the cash contributed
by the General Partner plus, in the case of cash contributions funded by an
offering of REIT Shares or other shares of capital stock of the General Partner,
the offering costs attributable to the cash contributed to the Partnership, and
(ii) in the case of the contribution of Properties (or any portion thereof) by
the General Partner which were acquired by the General Partner in exchange for
REIT Shares immediately prior to such contribution, the General Partner shall be
issued a number of Partnership Units equal to the number of REIT Shares issued
by the General Partner in exchange for such Properties, the Partnership Units
held by the other Partners shall not be adjusted, and the Partners' Percentage
Interests shall be adjusted accordingly. The General Partner shall promptly give
each Partner written notice of its Percentage Interest, as adjusted.

               F. Issuance of Performance Units to the PLPs. Performance
Investors may be required pursuant to the terms of the Escrow Agreements to
transfer all or a portion of their Performance Shares to the General Partner or
the Partnership (as applicable). To the extent Performance Shares (i.e., REIT
Shares) are transferred by Performance Investors to the General Partner pursuant
to the Escrow Agreements, the number of Partnership Units held by the General
Partner shall be automatically reduced by such amount on such date. To the
extent Performance Shares (i.e., Partnership Units) are transferred by
Performance Investors to the Partnership pursuant the Escrow Agreements, the
number of Partnership Units held by each such Performance Investor shall be
automatically reduced by such amount on such date. To the extent the Partnership
Units held by the General Partner or Performance Investors are reduced as set
forth in the preceding two sentences, the Partnership shall immediately issue an
equal number of Performance Units to the Persons listed on Schedule G-1 and
Schedule G-2 to Exhibit G in accordance with the allocations set forth on
Exhibit G. The adjustments in the number of Partnership Units held by the
Performance Partners and the PLPs set forth above shall have no effect on each
such Partners' Capital Account in the Partnership (except with respect to
subsequent allocations of items of Partnership income, gain, loss, deduction,
and credit made to such Partners and possibly with respect to the reissuance of
a Performance Unit subsequent to its forfeiture by a PLP) and no PLP shall have
an obligation to make a contribution to the capital of the Partnership in
connection with the issuance of Performance Units.

               Section 4.4 Stock Incentive Plan

               If at any time or from time to time the General Partner sells or
issues REIT Shares pursuant to any Stock Incentive Plan, the General Partner
shall contribute any proceeds therefrom to the Partnership as an additional
Capital Contribution and shall receive an amount of additional Partnership Units
equal to the number of REIT Shares so sold or issued. The General Partner's
Capital Account shall be increased by the amount of cash so contributed.

<PAGE>   32
               Section 4.5

               No Preemptive Rights

               Except to the extent expressly granted by the Partnership
pursuant to another agreement, no Person shall have any preemptive, preferential
or other similar right with respect to (i) additional Capital Contributions or
loans to the Partnership or (ii) issuance or sale of any Partnership Units or
other Partnership Interests.

               Section 4.6 Other Contribution Provisions

               In the event that any Partner is admitted to the Partnership and
is given (or is treated as having received) a Capital Account in exchange for
services rendered to the Partnership, such transaction shall be treated by the
Partnership and the affected Partner as if the Partnership had compensated such
Partner in cash, and the Partner had contributed such cash to the capital of the
Partnership. In addition, with the consent of the General Partner, in its sole
discretion, one or more Limited Partners may enter into contribution agreements
with the Partnership which have the effect of providing a guarantee of certain
obligations of the Partnership.

                                   ARTICLE 5.
                                  DISTRIBUTIONS

               Section 5.1 Requirement and Characterization of Distributions

               The General Partner shall cause the Partnership to distribute
all, or such portion as the General Partner may in its discretion determine,
Available Cash generated by the Partnership (i) first, to the extent that the
amount of cash distributed with respect to any Partnership Interests that are
entitled to any preference in distribution for any prior distribution period was
less than the required distribution for such outstanding Partnership Interests
for such prior distribution period, and to the extent such deficiency has not
been subsequently distributed pursuant to this Section 5.1 (a "Preferred
Distribution Shortfall"), in accordance with the rights of such class of
Partnership Interests (and within such class, pro rata in proportion to the
respective Percentage Interests on the applicable record date) and to the
Partners who are Partners on the applicable record date with respect to such
distribution, (ii) second, with respect to any Partnership Interests that are
entitled to any preference in distribution, in accordance with the rights of
such class of Partnership Interests (and within such class, pro rata in
proportion to the respective Percentage Interests on the applicable record date)
and (iii) third, with respect to Partnership Interests that are not entitled to
any preference in distribution, pro rata to each such class on a quarterly basis
and in accordance with the terms of such class to Partners who are Partners of
such class on the Partnership Record Date with respect to such distribution (and
within each such class, pro rata in proportion with the respective Percentage
Interests on such Partnership Record Date). Except as expressly provided for in
Article 16 with respect to the Series A Preferred Units, Article 17 with respect
to the Series B Preferred Units and in an agreement, if any, entered into in
connection with the creation of a new class of Partnership Interests in
accordance with Article 4, no Partnership Interest shall be entitled to a
distribution in preference to any other Partnership Interest. The General
Partner shall take such reasonable efforts, as determined by it in its sole and
absolute discretion and consistent with its qualification as a REIT, to cause
the Partnership to distribute sufficient amounts to enable the General Partner,
for so long as the General Partner has

                                       28

<PAGE>   33
determined to qualify as a REIT, to pay stockholder dividends that will (a)
satisfy the requirements for qualifying as a REIT under the Code and Regulations
("REIT Requirements") and (b) except to the extent otherwise determined by the
General Partner, avoid any Federal income or excise tax liability of the General
Partner, except to the extent that a distribution pursuant to clause (b) would
prevent the Partnership from making a distribution to the holders of Series B
Preferred Units in accordance with Section 17.3.

               Section 5.2 Distributions in Kind

               Except as expressly provided herein, no right is given to any
Partner to demand and receive property other than cash. The General Partner may
determine, in its sole and absolute discretion, to make a distribution in kind
to the Partners of Partnership assets, and such assets shall be distributed in
such a fashion as to ensure that the fair market value is distributed and
allocated in accordance with Articles 5, 6 and 10; provided, however, that, in
such case, the General Partners shall distribute only cash to the Series B
Limited Partners.

               Section 5.3 Distributions Upon Liquidation

               Proceeds from a Terminating Transaction shall be distributed to
the Partners in accordance with Section 13.2.

               Section 5.4 Distributions to Reflect Issuance of Additional
Partnership Interests

               In the event that the Partnership issues additional Partnership
Interests (other than Performance Units, which shall receive distributions as
set forth in Section 5.1) to the General Partner or any Additional Limited
Partner pursuant to Section 4.3.C or 4.4, the General Partner shall make such
revisions to this Article 5 as it determines are necessary to reflect the
issuance of such additional Partnership Interests. In the absence of any
agreement to the contrary, an Additional Limited Partner shall be entitled to
the distributions set forth in Section 5.1 (without regard to this Section 5.4)
with respect to the quarter during which the closing of its contribution to the
Partnership occurs, multiplied by a fraction the numerator of which is the
number of days from and after the date of such closing through the end of the
applicable quarter, and the denominator of which is the total number of days in
such quarter.

               Section 5.5 Section 5.5 Character of PLP Distributions

               Distributions to each PLP pursuant to this Agreement shall be
advances or drawings of money or property against such Partner's distributive
share of Net Income (or items thereof) as described in Treasury Regulation
Section 1.731-1(a)(1)(ii).

               Section 6.1 Timing and Amount of Allocations of Net Income and
Net Loss

               Net Income and Net Loss of the Partnership shall be determined
and allocated with respect to each fiscal year of the Partnership as of the end
of each such year. Subject to the other provisions of this Article 6, an
allocation to a Partner of a share of Net Income or Net Loss shall be treated as
an allocation of the same share of each item of income, gain, loss or deduction
that is taken into account in computing Net Income or Net Loss.

               Section 6.2 General Allocations

               A. In General. Except as otherwise provided in this Article 6,
Net Income and Net Loss allocable with respect to a class of Partnership
Interests, shall be allocated to each of the Partners holding such class of
Partnership Interests in accordance with their respective Percentage Interest of
such class.

                        allocated to the General Partner pursuant to Section
                        6.2.B.2(d) for all prior Partnership Years minus the
                        cumulative Net Income allocated to the General Partner

                        to the remainder, if any, of the cumulative Net Losses
                        allocated to each such Limited Partner pursuant to
                        Section 6.2.B.2(c) for all prior Partnership Years minus
                        the cumulative Net Income allocated to such Limited
                        Partner pursuant to this Section 6.2.B.1(b) for all
                        prior Partnership Years;

                (c)     Third, 100% to the General Partner and any other
                        Preferred Partners in an amount equal to the remainder,
                        if any, of the cumulative Net Losses allocated to such
                        Partners pursuant to Section 6.2.B.2(b) for all prior
                        Partnership Years minus the cumulative Net Income
                        allocated to such Partners pursuant to this Section
                        6.2.B.1(c) for all prior Partnership Years;

                (d)     Fourth, 100% to the General Partner and the Limited
                        Partners in an amount equal to the remainder, if any, of

                        Years minus the cumulative Net Income allocated to each
                        Partner pursuant to this Section 6.2.B.1(d) for all
                        prior Partnership Years;

                (e)     Fifth, 100% to the General Partner and any other
                        Preferred Partners in an amount equal to the excess of
                        (i) the sum of (x) in respect of the Series A Preferred
                        Units, an amount equal to the cumulative Series A
                        Priority Return to the last day of the current
                        Partnership Year or to the date of redemption, to the
                        extent Series A Preferred Units are redeemed during such
                        year, and (y) in respect of the Series B Preferred
                        Units, an amount equal to the cumulative Series B
                        Priority Return to the last day of the current
                        Partnership Year or to the date of redemption, to the
                        extent Series B Preferred Units are redeemed during such
                        year, over (ii) the cumulative Net Income allocated to
                        the General Partner or such Preferred Partner, as
                        applicable, pursuant to this Section 6.2.B.1(e) for all
                        prior Partnership Years; and

                (f)     Sixth, 100% to the General Partner and the Limited
                        Partners in accordance with their respective Percentage
                        Interests in the Common Units.

               To the extent the allocations of Net Income set forth above in
any paragraph of this Section 6.2.B.1 are not sufficient to entirely satisfy the
allocation set forth in such paragraph, such allocation shall be made in
proration to the total amount that would have been allocated pursuant to such
paragraph without regard to such shortfall.

               B.2. Net Losses. Except as provided in Section 6.2.B.3, Net
Losses for any Partnership Year shall be allocated in the following manner and
order of priority:

                (a)     First, 100% to the General Partner and the Limited
                        Partners in accordance with their respective Percentage

                        with this Section 6.2.B.2(a)) until the Adjusted Capital
                        Account (ignoring for this purpose any amounts a Partner
                        is obligated to contribute to the capital of the

                        and ignoring the Partner's Series A Preferred Capital
                        and Series B Preferred Capital) of each such Partner is
                        zero;

                (b)     Second, 100% to the General Partner and any other
                        Preferred Partners, pro rata to each such Partner's
                        Adjusted Capital Account (ignoring for this purpose any
                        amounts a Partner is obligated to contribute to the

                        Account (as so modified) of each such Partner is zero;

                (c)     Third, 100% to the Limited Partners to the extent of,
                        and in proportion to, the positive balance (if any) in
                        their Adjusted Capital Accounts; and

                (d)     Fourth, 100% to the General Partner.

               B.3. Terminating Capital Transactions.

                (a)     If no Performance Units are outstanding at the time of a
                        Terminating Capital Transaction, any Net Income
                        attributable to such Terminating Capital Transaction
                        shall first be allocated to the General Partner in an
                        amount equal to the Offering Costs, to the extent the
                        General Partner's Capital Account has not previously
                        been adjusted to account for such amounts.

                (b)     If Performance Units are outstanding at the time of a
                        Terminating Capital Transaction --

                        (1)     any Net Income attributable to such Terminating
                                Capital Transaction shall be allocated as
                                follows: such Net Income shall first be
                                tentatively allocated solely as an interim step
                                in calculating final allocations pursuant to
                                this Section 6.2.B.3(b)(1), among the Partners
                                in accordance with Section 6.2.B.3(a), Section
                                6.2.A and Section 6.2.B.1. Then the amount so
                                tentatively allocated to each Performance
                                Partner, to the extent of each such Performance
                                Partner's Excess Performance Capital, shall
                                instead be allocated to the PLPs, pro rata to
                                the number of Performance Units held by each
                                PLP.

                        (2)     any Net Loss attributable to such Terminating
                                Capital Transaction shall be allocated as
                                follows: such Net Loss shall first be
                                tentatively allocated, solely as an interim step
                                in calculating final allocations pursuant to
                                this Section 6.2.B.3(b)(2), among the Partners
                                in accordance with Section 6.2.A and Section
                                6.2.B.2. Then the amount so tentatively
                                allocated to the PLPs shall instead be allocated
                                to the Performance Partners to the extent of the
                                aggregate Excess Performance Capital of the
                                Performance Partners. Any amounts so allocated
                                away from the PLPs shall be done on a basis
                                which is proportionate to each PLP's Performance
                                Units. Any amounts so allocated to the
                                Performance Partners shall be done on a basis
                                which is proportionate to each Performance
                                Partner's Excess Performance Capital.

               C. Allocations to Reflect Issuance of Additional Partnership
Interests. In the event that the Partnership issues additional Partnership
Interests to the General Partner or any Additional Limited Partner pursuant to
Section 4.3 or 4.4, the General Partner shall make such revisions to this
Section 6.2 or to Section 12.2.B as it determines are necessary to reflect the
terms of the issuance of such additional Partnership Interests, including making
preferential allocations to certain classes of Partnership Interests, subject to
the terms of the Series A Preferred Units and the Series B Preferred Units. In
addition, for any quarter in which Performance Units were issued, Net Income and
Net Loss relating to such units shall be allocated among (i) the PLPs who
received such units and (ii) the Performance Partners who returned the

                                       32

corresponding Partnership Units to the Partnership, in accordance with any
method selected by the General Partner which is permitted under Section 706 of
the Code.

               Section 6.3 Additional Allocation Provisions

               Notwithstanding the foregoing provisions of this Article 6:

               A. Regulatory Allocations.

                      (i) Minimum Gain Chargeback. Except as otherwise provided
        in Regulations Section 1.704-2(f), notwithstanding the provisions of
        Section 6.2, or any other provision of this Article 6, if there is a net
        decrease in Partnership Minimum Gain during any fiscal year, each
        Partner shall be specially allocated items of Partnership income and
        gain for such year (and, if necessary, subsequent years) in an amount
        equal to such Partner's share of the net decrease in Partnership Minimum
        Gain, as determined under Regulations Section 1.704-2(g). Allocations
        pursuant to the previous sentence shall be made in proportion to the
        respective amounts required to be allocated to each Partner pursuant
        thereto. The items to be allocated shall be determined in accordance
        with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section
        6.3.A(i) is intended to qualify as a "minimum gain chargeback" within
        the meaning of Regulation Section 1.704-2(f) which shall be controlling
        in the event of a conflict between such Regulation and this Section
        6.3.A(i).

                      (ii) Partner Minimum Gain Chargeback. Except as otherwise
        provided in Regulations Section 1.704-2(i)(4), and notwithstanding the
        provisions of Section 6.2, or any other provision of this Article 6
        (except Section 6.3.A(i)), if there is a net decrease in Partner Minimum
        Gain attributable to a Partner Nonrecourse Debt during any fiscal year,
        each Partner who has a share of the Partner Minimum Gain attributable to
        such Partner Nonrecourse Debt, determined in accordance with Regulations
        Section 1.704-2(i)(5), shall be specially allocated items of Partnership
        income and gain for such year (and, if necessary, subsequent years) in
        an amount equal to such Partner's share of the net decrease in Partner
        Minimum Gain attributable to such Partner Nonrecourse Debt, determined
        in accordance with Regulations Section 1.704-2(i)(4). Allocations
        pursuant to the previous sentence shall be made in proportion to the
        respective amounts required to be allocated to each General Partner and
        Limited Partner pursuant thereto. The items to be so allocated shall be
        determined in accordance with Regulations Sections 1.704-2(i)(4) and
        1.704-2(j)(2). This Section 6.3.A(ii) is intended to qualify as a
        "chargeback of partner nonrecourse debt minimum gain" within the meaning
        of Regulation Section 1.704-2(i) which shall be controlling in the event
        of a conflict between such Regulation and this Section 6.3.A(ii).

                      (iii) Nonrecourse Deductions and Partner Nonrecourse
        Deductions. Any Nonrecourse Deductions for any fiscal year shall be
        specially allocated to the Partners in accordance with their respective
        Percentage Interest in Common Units. Any Partner Nonrecourse Deductions
        for any fiscal year shall be specially allocated to the Partner(s) who
        bears the economic risk of loss with respect to the Partner Nonrecourse

                                       33

<PAGE>   38
        Debt to which such Partner Nonrecourse Deductions are attributable, in
        accordance with Regulations Sections 1.704-2(b)(4) and 1.704-2(i).

                      (iv) Qualified Income Offset. If any Partner unexpectedly
        receives an adjustment, allocation or distribution described in
        Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of
        Partnership income and gain shall be allocated, in accordance with
        Regulations Section 1.704-1(b)(2)(ii)(d), to the Partner in an amount
        and manner sufficient to eliminate, to the extent required by such
        Regulations, the Adjusted Capital Account Deficit of the Partner as
        quickly as possible provided that an allocation pursuant to this Section
        6.3.A(iv) shall be made if and only to the extent that such Partner
        would have an Adjusted Capital Account Deficit after all other
        allocations provided in this Article 6 have been tentatively made as if
        this Section 6.3.A(iv) were not in the Agreement. It is intended that
        this Section 6.3.A(iv) qualify and be construed as a "qualified income
        offset" within the meaning of Regulations 1.704-1(b)(2)(ii)(d), which
        shall be controlling in the event of a conflict between such Regulations
        and this Section 6.3.A(iv).

                      (v) Gross Income Allocation. In the event any Partner has
        a deficit Capital Account at the end of any fiscal year which is in
        excess of the sum of (a) the amount (if any) such Partner is obligated
        to restore to the Partnership and (b) the amount such Partner is deemed
        to be obligated to restore pursuant to Regulations Section
        1.704-1(b)(2)(ii)(c) or the penultimate sentences of Regulations
        Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be
        specially allocated items of Partnership income and gain in the amount
        of such excess as quickly as possible; provided, that an allocation
        pursuant to this Section 6.3.A(v) shall be made if and only to the
        extent that such Partner would have a deficit Capital Account in excess
        of such sum after all other allocations provided in this Article 6 have
        been tentatively made as if this Section 6.3.A(v) and Section 6.3.A(iv)
        were not in the Agreement.

                      (vi) Limitation on Allocation of Net Loss. To the extent
        any allocation of Net Loss would cause or increase an Adjusted Capital
        Account Deficit as to any Partner, such allocation of Net Loss shall be
        reallocated among the other Partners in accordance with their respective
        Percentage Interests in Common Units, subject to the limitations of this
        Section 6.3.A(vi).

                      (vii) Section 754 Adjustment. To the extent an adjustment
        to the adjusted tax basis of any Partnership asset pursuant to Code
        Section 734(b) or Code Section 743(b) is required, pursuant to
        Regulations Section 1.704-1(b)(2)(iv)(m)(2) or Regulations Section
        1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital
        Accounts as the result of a distribution to a Partner in complete
        liquidation of his interest in the Partnership, the amount of such
        adjustment to the Capital Accounts shall be treated as an item of gain
        (if the adjustment increases the basis of the asset) or loss (if the
        adjustment decreases such basis) and such gain or loss shall be
        specially allocated to the Partners in accordance with their interests
        in the Partnership in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(2) applies, or to the Partners to whom such
        distribution was made in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(4) applies.

                      (viii) Curative Allocation. The allocations set forth in
        Sections 6.3.A(i), (ii), (iii), (iv), (v), (vi), and (vii) (the
        "Regulatory Allocations") are intended to comply with certain regulatory
        requirements, including the requirements of Regulations Sections
        1.704-1(b) and 1.704-2. Notwithstanding the provisions of Sections 6.1
        and 6.2, the Regulatory Allocations shall be taken into account in
        allocating other items of income, gain, loss and deduction among the
        Partners so that, to the extent possible, the net amount of such
        allocations of other items and the Regulatory Allocations to each
        Partner shall be equal to the net amount that would have been allocated
        to each such Partner if the Regulatory Allocations had not occurred.

               B. For purposes of determining a Partner's proportional share of
the "excess nonrecourse liabilities" of the Partnership within the meaning of
Regulations Section 1.752-3(a)(3), each Partner's interest in Partnership
profits shall be such Partner's Percentage Interest in Common Units.

               Section 6.4 Tax Allocations

               A. In General. Except as otherwise provided in this Section 6.4,
for income tax purposes each item of income, gain, loss and deduction
(collectively, "Tax Items") shall be allocated among the Partners in the same
manner as its correlative item of "book" income, gain, loss or deduction is
allocated pursuant to Sections 6.2 and 6.3.

               B. Allocations Respecting Section 704(c) Revaluations.
Notwithstanding Section 6.4.A, Tax Items with respect to Partnership property
that is contributed to the Partnership by a Partner shall be shared among the
Partners for income tax purposes pursuant to Regulations promulgated under
Section 704(c) of the Code, so as to take into account the variation, if any,
between the basis of the property to the Partnership and its initial Gross Asset
Value. With respect to Partnership property that is initially contributed to the
Partnership upon its formation pursuant to Section 4.1, such variation between
basis and initial Gross Asset Value shall be taken into account under the
"traditional method" as described in Regulations Section 1.704-3(b). With
respect to properties subsequently contributed to the Partnership, the
Partnership shall account for such variation under any method approved under
Section 704(c) of the Code and the applicable regulations as chosen by the
General Partner. In the event the Gross Asset Value of any Partnership asset is
adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value
(provided in Article 1), subsequent allocations of Tax Items with respect to
such asset shall take account of the variation, if any, between the adjusted
basis of such asset and its Gross Asset Value in the same manner as under
Section 704(c) of the Code and the applicable regulations consistent with the
requirements of Regulations Section 1.704-1(b)(2)(iv)(g) using any method
approved under 704(c) of the Code and the applicable regulations as chosen by
the General Partner.

                        Partnership to make distributions to its Partners in
                        such amounts as will permit the General Partner (for so
                        long as the General Partner has determined to qualify as
                        a REIT) to avoid the payment of any Federal income tax
                        (including, for this purpose, any excise tax pursuant to
                        Section 4981 of the Code) and to make distributions to

                        Partner to maintain REIT status), the assumption or
                        guarantee of, or other contracting for, indebtedness and
                        other liabilities, the issuance of evidences of
                        indebtedness (including the securing of same by
                        mortgage, deed of trust or other lien or encumbrance on
                        all or any of the Partnership's assets) and the
                        incurring of any obligations it deems necessary for the
                        conduct of the activities of the Partnership;

                        or other agencies having jurisdiction over the business
                        or assets of the Partnership;

                (iii)   subject to the provisions of Section 7.3.D, the
                        acquisition, disposition, mortgage, pledge, encumbrance,
                        hypothecation or exchange of any assets of the

                        subsidiary of the General Partner or the Partnership)
                        and any Subsidiaries of the Partnership) and the

                        the General Partner considers useful or necessary to the
                        conduct of the Partnership's operations or the

                        having titles such as "president," "vice president,"

                        and other terms of employment or hiring, including
                        waivers of conflicts of interest and the payment of

                        assets;

                (viii)  the maintenance of such insurance for the benefit of the
                        Partnership and the Partners as it deems necessary or

                        the contributions of property to any Subsidiary and any
                        other Person in which it has an equity investment from
                        time to time); provided that, as long as the General
                        Partner has determined to continue to qualify as a REIT,
                        the Partnership may not engage in any such formation,
                        acquisition or contribution that would cause the General

                        indemnification of any Person against liabilities and
                        contingencies to the extent permitted by law;

                (xi)    the undertaking of any action in connection with the
                        Partnership's direct or indirect investment in any
                        Person (including, without limitation,

                        contributing or loaning Partnership funds to, incurring
                        indebtedness on behalf of, or guarantying the

                        Partnership property distributed in kind using such
                        reasonable method of valuation as it may adopt; provided
                        that, such methods are otherwise consistent with
                        requirements of this Agreement;

                        Partnership;

                (xvi)   the exercise, directly or indirectly through any

                        Partnership;

                (xvii)  the exercise of any of the powers of the General Partner
                        enumerated in this Agreement on behalf of or in
                        connection with any Subsidiary of the Partnership or any
                        other Person in which the Partnership has a direct or
                        indirect interest, or jointly with any such Subsidiary
                        or other Person;

                (xviii) the exercise of any of the powers of the General Partner
                        enumerated in this Agreement on behalf of any Person in
                        which the Partnership does not have an interest,
                        pursuant to contractual or other arrangements with such
                        Person; and

                (xix)   the making, execution and delivery of any and all deeds,
                        leases, notes, deeds to secure debt, mortgages, deeds of

                        guarantees, warranties, indemnities, waivers, releases
                        or legal instruments or other agreements in writing
                        necessary or appropriate in the judgment of the General
                        Partner for the accomplishment of any of the powers of
                        the General Partner enumerated in this Agreement.

               B. Each of the Limited Partners agrees that the General Partner
is authorized to execute, deliver and perform the above-mentioned agreements and
transactions on behalf of the Partnership without any further act, approval or
vote of the partners, notwithstanding any other provisions of this Agreement
(except as provided in Section 7.3), the Act or any applicable law, rule or
regulation. The execution, delivery or performance by the General Partner or the
Partnership of any agreement authorized or permitted under this Agreement shall
not constitute a breach by the General Partner of any duty that the General
Partner may owe the Partnership or

                                       38

<PAGE>   43
the Limited Partners or any other Persons under this Agreement or of any duty
stated or implied by law or equity.

               C. At all times from and after the date hereof, the General
Partner may cause the Partnership to obtain and maintain (i) casualty, liability
and other insurance (including, without limitation, earthquake insurance) on the
properties of the Partnership and (ii) liability insurance for the Indemnities
hereunder.

               D. At all times from and after the date hereof, the General
Partner may cause the Partnership to establish and maintain working capital and
other reserves in such amounts as the General Partner, in its sole and absolute
discretion, deems appropriate and reasonable from time to time.

               E. In exercising its authority under this Agreement, the General
Partner may, but other than as set forth in the following sentence and as
expressly set forth in the agreements listed on Exhibit I hereto, shall be under
no obligation to, take into account the tax consequences to any Partner
(including the General Partner) of any action taken by the General Partner. The
General Partner, on behalf of the Partnership, shall use commercially reasonable
efforts to cooperate with the Limited Partners to minimize any taxes payable in
connection with any sale, exchange or any other disposition of assets of the
Partnership. The General Partner and the Partnership shall not have liability to
a Limited Partner under any circumstances as a result of an income tax liability
incurred by such Limited Partner as a result of an action (or inaction) by the
General Partner pursuant to its authority under this Agreement.

               F. 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
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.

               Section 7.2 Certificate of Limited Partnership

               To the extent that such action is determined by the General
Partner to be reasonable and necessary or appropriate, the General Partner shall
file amendments to and restatements of the Certificate and do all the things to
maintain the Partnership as a limited partnership (or a partnership in which the
limited partners have limited liability) under the laws of the State of Delaware
and to maintain the Partnership's qualification to do business as a foreign
limited partnership in each other state, the District of Columbia or other
jurisdiction, in which the Partnership may elect to do business or own property.
Subject to the terms of Section 8.5.A(iv), the General Partner shall not be
required, before or after filing, to deliver or mail a copy of the Certificate
or any amendment thereto to any Limited Partner. The General Partner shall use
all reasonable efforts to cause to be filed such other certificates or documents
as may be reasonable and necessary or appropriate for the formation,
continuation, qualification and operation of a limited partnership (or a
partnership in which the limited partners have limited

                                       39

<PAGE>   44
liability) in the State of Delaware, and any other state, or the District of
Columbia or other jurisdiction, in which the Partnership may elect to do
business or own property.

               Section 7.3 Restrictions on General Partner's Authority

               A. The General Partner may not take any action in contravention
of this Agreement, including, without limitation:

                (i)     take any action that would make it impossible to carry
                        on the ordinary business of the Partnership, except as
                        otherwise provided in this Agreement;

                (ii)    possess Partnership property, or assign any rights in
                        specific Partnership property, for other than a
                        Partnership purpose except as otherwise provided in this
                        Agreement;

                (iii)   admit a Person as a Partner, except as otherwise
                        provided in this Agreement (including with respect to
                        the PLPs, who shall become Partners upon their receipt
                        of Performance Units);

                (iv)    perform any act that would subject a Limited Partner to
                        liability as a general partner in any jurisdiction or
                        any other liability except as provided herein or under
                        the Act; or

                (v)     enter into any contract, mortgage, loan or other
                        agreement that prohibits or restricts, or has the effect
                        of prohibiting or restricting, the ability of a Limited
                        Partner to exercise its rights to a Redemption in full,
                        except with the written consent of such Limited Partner.

               B. The General Partner shall not, without the prior Consent of
the Partners (in addition to any Consent of the Limited Partners required by any
other provision hereof), undertake, on behalf of the Partnership, any of the
following actions or enter into any transaction which would have the effect of
such transactions:

                (i)     except as provided in Section 7.3.D below, amend, modify
                        or terminate this Agreement other than to reflect the
                        admission, substitution, termination or withdrawal of
                        partners pursuant to Article 12;

                (ii)    make a general assignment for the benefit of creditors
                        or appoint or acquiesce in the appointment of a
                        custodian, receiver or trustee for all or any part of
                        the assets of the Partnership;

                (iii)   institute any proceeding for bankruptcy on behalf of the
                        Partnership;

                (iv)    confess a judgment against the Partnership; or

                (v)     enter into a merger (including a triangular merger),
                        consolidation or other combination of the Partnership
                        with or into another entity.

                                       40

<PAGE>   45
               C. Except in the case of a Liquidating Event pursuant to Section
13.1 (other than Section 13.1.F), the General Partner shall not, without the
prior Consent of the Limited Partners, undertake, on behalf of the Partnership,
any actions or enter into any transaction which would have the effect of a
dissolution of the Partnership, including a sale, exchange, transfer or other
disposition of all or substantially all of the Partnership's assets in a single
transaction or a series of related transactions.

               D. Notwithstanding Sections 7.3.B and 7.3.C, but subject to
Section 7.3.E, the General Partner shall have the power, without the Consent of
the Partners, to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

                (i)     to add to the obligations of the General Partner or
                        surrender any right or power granted to the General
                        Partner or any Affiliate of the General Partner for the
                        benefit of the Limited Partners;

                (ii)    to reflect the issuance of additional Partnership
                        Interests pursuant to Sections 4.3.C, 4.3.F and 4.4, or
                        the admission, substitution, termination, reduction in
                        Partnership Units or withdrawal of Partners in
                        accordance with this Agreement (which may be effected
                        through the replacement of Exhibit A with an amended
                        Exhibit A);

                (iii)   to set forth or amend the designations, rights, powers,
                        duties, and preferences of the holders of any additional
                        Partnership Interests issued pursuant to Article 4;

                (iv)    to reflect a change that is of an inconsequential nature
                        and does not adversely affect the Limited Partners in
                        any material respect, or to cure any ambiguity in,
                        correct or supplement any provision, or make other
                        changes with respect to matters arising under, this
                        Agreement that will not be inconsistent with law or with
                        the provisions of this Agreement;

                (v)     to satisfy any requirements, conditions, or guidelines
                        contained in any order, directive, opinion, ruling or
                        regulation of a Federal, state of local agency or
                        contained in Federal, state or local law.

                (vi)    to reflect such changes as are reasonably necessary for
                        the General Partner to maintain its status as a REIT,
                        including changes which may be necessitated due to a
                        change in applicable law (or an authoritative
                        interpretation thereof) or a ruling of the IRS; and

                (vii)   to modify, as set forth in the definition of "Capital
                        Account," the manner in which Capital Accounts are
                        computed.

The General Partner will provide notice to the Limited Partners when any action
under this Section 7.3.D is taken.

                                       41

<PAGE>   46
               E. Notwithstanding Sections 7.3.B, 7.3.C and 7.3.D, this
Agreement shall not be amended, and no action may be taken by the General
Partner, including in either case through merger or sale of assets of the
Partnership or otherwise, without the Consent of each Common Limited Partner or
Preferred Limited Partner adversely affected if such amendment or action would
(i) convert a Limited Partner's interest in the Partnership into a general
partner's interest (except as the result of the General Partner acquiring such
interest), (ii) modify the limited liability of a Limited Partner, (iii) alter
rights of the Partner to receive distributions pursuant to Article 5, Section
13.2.A(4) or Article 16 or the allocations specified in Article 6 (except as
permitted pursuant to Section 4.3 and Section 7.3.D), (iv) alter or modify the
rights to a Redemption or the REIT Shares Amount as set forth in Section 8.6,
and related definitions hereof, (v) alter the Redemption or exchange rights as
set forth in Sections 17.5 and 17.8 hereof, respectively, or (vi) amend this
Section 7.3.E. Further, no amendment may alter the restrictions on the General
Partner's authority set forth elsewhere in this Section 7.3 without the Consent
specified in such section. In addition, (a) Section 11.2 of this Agreement shall
not be amended, and no action in contravention of Section 11.2 shall be taken,
including in either case through merger or sale of assets of the Partnership or
otherwise, without the Consent of the Limited Partners and (b) this Agreement
shall not be amended, and no action shall be taken, including in either case
through merger or sale of assets of the Partnership or otherwise, which would
adversely affect the rights of the Persons set forth in Exhibit G to receive
Performance Units as described herein.

               F. Other than incident to a transaction pursuant to Sections
11.2.B or 11.2.C, the General Partner shall not undertake to dispose of any
Partnership Property specified in the agreements listed in Exhibit H in a
taxable sale or taxable exchange prior to the dates specified in such agreements
without the prior consent of each Limited Partner which contributed all or any
portion of an interest in such Property to the Partnership, as set forth in such
agreements.

               Section 7.4 Reimbursement of the General Partner

               A. Except as provided in this Section 7.4 and elsewhere in this
Agreement (including the provisions of Articles 5 and 6 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.

               B. Subject to Section 15.11, 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 expenses it incurs
relating to the ownership of interests in and operation of, or for the benefit
of, the Partnership. The Limited Partners acknowledge that the General Partner's
sole business is the ownership of interests in and operation of the Partnership
and that such expenses are incurred for the benefit of the Partnership; provided
that, the General Partner shall not be reimbursed for expenses it incurs
relating to the organization of the Partnership and the General Partner, or the
initial public offering or subsequent offerings of REIT Shares, other shares of
capital stock or Funding Debt by the General Partner, but shall be reimbursed
for expenses it incurs with respect to any other issuance of additional
Partnership Interests pursuant to the provisions hereof. Such reimbursements
shall be in addition to any reimbursement to the General Partner as a result of
indemnification pursuant to Section 7.7.

                                       42

<PAGE>   47
               C. If and to the extent any reimbursements to the General Partner
pursuant to this Section 7.4 constitute gross income of the General Partner (as
opposed to the repayment of advances made by the General Partner on behalf of
the Partnership), such amounts shall constitute guaranteed payments within the
meaning of Section 707(c) of the Code, shall be treated consistently therewith
by the Partnership and all Partners, and shall not be treated as distributions
for purposes of computing the Partners' Capital Accounts.

               Section 7.5 Outside Activities of the General Partner

               A. Except in connection with a transaction authorized in Section
11.2, without the Consent of the Limited Partners, the General Partner shall
not, directly or indirectly, enter into or conduct any business, other than in
connection with the ownership, acquisition and disposition of Partnership
Interests as a General Partner and the management of the business of the
Partnership, its operation as a public reporting company with a class (or
classes) of securities registered under the Exchange Act, its operation as a
REIT and such activities as are incidental to the same. Without the Consent of
the Limited Partners, the General Partner shall not, directly or indirectly,
participate in or otherwise acquire any interest in any real or personal
property, except its General Partner Interest, its interest in any Subsidiary
Partnership(s) (held directly or indirectly through a Qualified REIT Subsidiary)
that the General Partner holds in order to maintain such Subsidiary
Partnership's status as a partnership, and such bank accounts, similar
instruments or other short-term investments as it deems necessary to carry out
its responsibilities contemplated under this Agreement and the Charter. In the
event the General Partner desires to contribute cash to any Subsidiary
Partnership to acquire or maintain an interest of 1% or less in the capital of
such partnership, the General Partner may acquire such cash from the Partnership
in exchange for a reduction in the General Partner's Units, in an amount equal
to the amount of such cash divided by the Fair Market Value of a REIT Share on
the day such cash is received by the General Partner. Notwithstanding the
foregoing, the General Partner may acquire Properties in exchange for REIT
Shares, to the extent such Properties are immediately contributed by the General
Partner to the Partnership, pursuant to the terms described in Section 4.3.E.
Any Limited Partner Interests acquired by the General Partner, whether pursuant
to exercise by a Limited Partner of its right of Redemption, or otherwise, shall
be automatically converted into a General Partner Interest comprised of an
identical number of Partnership Units with the same rights, priorities and
preferences as the class or series so acquired. If, at any time, the General
Partner acquires material assets (other than on behalf of the Partnership) the
definition of "REIT Shares Amount" and the definition of "Deemed Value of
Partnership Interests" shall be adjusted, as reasonably agreed to by the General
Partner and the other Limited Partners, to reflect the relative Fair Market
Value of a share of capital stock of the General Partner relative to the Deemed
Partnership Interest Value of the related Partnership Unit. The General
Partner's General Partner Interest in the Partnership, its minority interest in
any Subsidiary Partnership(s) (held directly or indirectly through a Qualified
REIT Subsidiary) that the General Partner holds in order to maintain such
Subsidiary Partnership's status as a partnership, and interests in such
short-term liquid investments, bank accounts or similar instruments as the
General Partner deems necessary to carry out its responsibilities contemplated
under this Agreement and the Charter are interests which the General Partner is
permitted to acquire and hold for purposes of this Section 7.5.A.

                                       43

<PAGE>   48
               B. In the event the General Partner exercises its rights under
the Charter to purchase REIT Shares or Preferred Shares, then the General
Partner shall cause the Partnership to redeem from it a number of Partnership
Units of the appropriate class as determined based on, in the case of REIT
Shares, the REIT Shares Amount equal to the number of REIT Shares so purchased,
or in the case of Preferred Shares an equal number of Preferred Units which
correspond in ranking to the Preferred Shares so purchased, in each case on the
same terms that the General Partner purchased such REIT Shares or Preferred
Shares (as applicable).

               Section 7.6 Contracts with Affiliates

               A. Except as expressly permitted by this Agreement, the
Partnership shall not, directly or indirectly, sell, transfer or convey any
property to, or purchase any property from, or borrow funds from, or lend funds
to, any Partner or any Affiliate of the Partnership that is not also a
Subsidiary of the Partnership, except pursuant to transactions that are on terms
that are fair and reasonable and no less favorable to the Partnership than would
be obtained from an unaffiliated third party.

               B. The General Partner, in its sole and absolute discretion and
without the approval of the Limited Partners, may propose and adopt on behalf of
the Partnership employee benefit plans funded by the Partnership for the benefit
of employees of the General Partner, the Partnership, Subsidiaries of the
Partnership or any Affiliate of any of them in respect of services performed,
directly or indirectly, for the benefit of the Partnership, the General Partner,
or any of the Partnership's Subsidiaries. The General Partner also is expressly
authorized to cause the Partnership to issue to it Partnership Units
corresponding to REIT Shares issued by the General Partner pursuant to its Stock
Incentive Plan or any similar or successor plan and to repurchase such
Partnership Units from the General Partner to the extent necessary to permit the
General Partner to repurchase such REIT Shares in accordance with such plan.

               Section 7.7 Indemnification

               A. The Partnership shall indemnify an Indemnitee from and against
any and all losses, claims, damages, liabilities, joint or several, expenses
(including 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, unless it is
established that: (i) the act or omission of the Indemnitee was material to the
matter giving rise to the proceeding and either was committed in bad faith or
was the result of active and deliberate dishonesty; (ii) the Indemnitee actually
received an improper personal benefit in money, property or services; or (iii)
in the case of any criminal proceeding, the Indemnitee had reasonable cause to
believe that the act or omission was unlawful. Without limitation, the foregoing
indemnity shall extend to any liability of any Indemnitee, pursuant to a loan
guaranty or otherwise, for any indebtedness of the Partnership or any Subsidiary
of the Partnership (including, without limitation, any indebtedness which the
Partnership or any Subsidiary of the Partnership has assumed or taken subject
to), and the General Partner is hereby authorized and empowered, on behalf of
the Partnership, to enter into one or more indemnity agreements consistent with
the provisions of this

                                       44

<PAGE>   49
Section 7.7 in favor of any Indemnitee having or potentially having liability
for any such indebtedness. The 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 7.7.A. The termination
of any proceeding by conviction or upon a plea of nolo contendere or its
equivalent, or any entry of an order of probation prior to judgment, creates a
rebuttable presumption that the Indemnitee acted in a manner contrary to that
specified in this Section 7.7.A. Any indemnification pursuant to this Section
7.7 shall be made only out of the assets of the Partnership, and any insurance
proceeds from the liability policy covering the General Partner and any
Indemnitee, and neither the General Partner nor any Limited Partner shall have
any obligation to contribute to the capital of the Partnership or otherwise
provide funds to enable the Partnership to fund its obligations under this
Section 7.7.

               B. Reasonable expenses incurred by an Indemnitee who is a party
to a proceeding may be paid or reimbursed by the Partnership 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 Section 7.7.A has been met and (ii) a written undertaking by or on
behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.

               C. The indemnification provided by this Section 7.7 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, on behalf
of 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 any 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 7.7, the Partnership shall be
deemed to have requested an Indemnitee to serve as fiduciary of an employee
benefit plan whenever the performance by it of its duties to the Partnership
also imposes duties on, or otherwise involves services by, it to the plan or
participants or beneficiaries of the plan; excise taxes assessed on an
Indemnitee with respect to an employee benefit plan pursuant to applicable law
shall constitute fines within the meaning of Section 7.7; and 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 7.7 because the Indemnitee had an interest in the
transaction with respect to

                                       45

<PAGE>   50
which the indemnification applies if the transaction was otherwise permitted by
the terms of this Agreement.

               H. The provisions of this Section 7.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the
Partnership's liability to any Indemnitee under this Section 7.7 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

               I. If and to the extent any reimbursements to the General Partner
pursuant to this Section 7.7 constitute gross income of the General Partner (as
opposed to the repayment of advances made by the General Partner on behalf of
the Partnership) such amounts shall constitute guaranteed payments within the
meaning of Section 707(c) of the Code, shall be treated consistently therewith
by the Partnership and all Partners, and shall not be treated as distributions
for purposes of computing the Partners' Capital Accounts.

               J. Any indemnification hereunder is subject to, and limited by,
the provisions of Section 17-108 of the Act.

               K. In the event the Partnership is made a party to any litigation
or otherwise incurs any loss or expense as a result of or in connection with any
Partner's personal obligations or liabilities unrelated to Partnership business,
such Partner shall indemnify and reimburse the Partnership for all such loss and
expense incurred, including legal fees, and the Partnership Interest of such
Partner may be charged therefor. The liability of a Partner under this Section
7.7.K shall not be limited to such Partner's Partnership Interest, but shall be
enforceable against such Partner personally.

               Section 7.8 Liability of the General Partner

               A. Notwithstanding anything to the contrary set forth in this
Agreement, none of the General Partner and any of its officers, directors,
agents and employees shall be liable or accountable in damages or otherwise to
the Partnership, any Partners or any Assignees, or their successors or assigns,
for losses sustained, liabilities incurred or benefits not derived as a result
of errors in judgment or mistakes of fact or law or any act or omission if the
General Partner acted in good faith.

               B. The Limited Partners expressly acknowledge that the General
Partner is acting for the benefit of the Partnership, the Limited Partners and
the General Partner's stockholders collectively, that the General Partner is
under no obligation to give priority to the separate interests of the Limited
Partners or the General Partner's stockholders (including, without limitation,
the tax consequences to Limited Partners or Assignees or to stockholders) in
deciding whether to cause the Partnership to take (or decline to take) any
actions and that the General Partner shall not be liable to the Partnership or
to any Limited Partner for monetary

                                       46

<PAGE>   51
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 7.1.A, the General Partner may exercise any of the powers
granted to it by 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. In no event shall the liability of the
General Partner and its officers, directors, agents and employees, to the
Partnership and the Limited Partners under this Section 7.8 be greater than the
Partnership Interest of the General Partner.

               D. Any amendment, modification or repeal of this Section 7.8 or
any provision hereof shall be prospective only and shall not in any way affect
the limitations on the liability of the General Partner and any of its officers,
directors, agents and employees to the Partnership and the Limited Partners
under this Section 7.8 as in effect immediately prior to such amendment,
modification or repeal with respect to claims arising from or relating to
matters occurring, in whole or in part, prior to such amendment, modification or
repeal, regardless of when such claims may arise or be asserted.

               Section 7.9 Other Matters Concerning the General Partner

               A. The General Partner may rely and shall be protected in acting
or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, debenture,
or other paper or document believed by it to be genuine and to have been signed
or presented by the proper party or parties.

               B. The General Partner may consult with legal counsel,
accountants, appraisers, management consultants, investment bankers and other
consultants and advisers selected by it, and any act taken or omitted to be
taken in reliance upon the opinion of such Persons as to matters which such
General Partner reasonably believes to be within such Person's professional or
expert competence shall be conclusively presumed to have been done or omitted in
good faith and in accordance with such opinion.

               C. The General Partner shall have the right, in respect of any of
its powers or obligations hereunder, to act through any of its duly authorized
officers and a duly appointed attorney or attorneys-in-fact. Each such attorney
shall, to the extent provided by the General Partner in the power of attorney,
have full power and authority to do and perform all and every act and duty which
is permitted or required to be done by the General Partner hereunder.

               D. Notwithstanding any other provisions of this Agreement or any
non-mandatory provision of 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 protect the ability of
the General Partner, for so long as the General Partner has determined to
qualify as a REIT, to (i) continue to qualify as a REIT or (ii) except with
respect to the distribution of Available Cash to the Series B Limited Partners
in accordance with Section 17.3 avoid the General Partner incurring any taxes
under Section 857 or Section 4981 of the Code, is

                                       47

<PAGE>   52
expressly authorized under this Agreement and is deemed approved by all of the
Limited Partners.

               E. So long as the Company holds any interest in the Partnership
(as either a General Partner or Limited Partner), the Company shall have
"management rights" (as such term is defined in the Plan Asset Regulation) with
respect to the Partnership and its Properties to the extent necessary to qualify
the Company as a "venture capital operating company" (as such term is defined in
the Plan Asset Regulation).

               Section 7.10 Title to Partnership Assets

               Title to 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 Partners, individually or collectively, shall have any
ownership interest in such Partnership assets or any portion thereof. 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 deemed held by the General Partner or such nominee or
Affiliate for the use and benefit of the Partnership in accordance with the
provisions of this Agreement; provided, however, that the General Partner shall
use its best efforts to cause beneficial and record 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.

               Section 7.11 Reliance by Third Parties

               Notwithstanding anything to the contrary in this Agreement, any
Person dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority to encumber, sell or otherwise use in any
manner any and all assets of the Partnership and to enter into any contracts on
behalf of the Partnership, and such Person shall be entitled to deal with the
General Partner as if it were the Partnership's sole party in interest, both
legally and beneficially. Each Limited Partner hereby waives any and all
defenses or other remedies which may be available against such Person to
contest, negate or disaffirm any action of the General Partner in connection
with any such dealing. In no event shall any Person dealing with the General
Partner or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or its representatives. Each and
every certificate, document or other instrument executed on behalf of the
Partnership by the General Partner or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and delivery of such certificate, document
or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

               Section 8.1 Limitation of Liability

               The Limited Partners shall have no liability under this Agreement
except as expressly provided in this Agreement or under the Act.

               Section 8.2 Management of Business

               No Limited Partner or Assignee (other than the General Partner,
any of its Affiliates or any officer, director, employee, general partner, agent
or trustee of the General Partner, the Partnership or any of their Affiliates,
in their capacity as such) shall take part in the operations, management or
control (within the meaning of the Act) of the Partnership's business, transact
any business in the Partnership's name or have the power to sign documents for
or otherwise bind the Partnership. The transaction of any such business by the
General Partner, any of its Affiliates or any officer, director, employee,
general partner, agent or trustee of the General Partner, the Partnership or any
of their Affiliates, in their capacity as such, shall not affect, impair or
eliminate the limitations on the liability of the Limited Partners or Assignees
under this Agreement.

               Section 8.3 Outside Activities of Limited Partners

               Subject to any agreements entered into by a Limited Partner or
its Affiliates with the General Partner, Partnership or a Subsidiary, any
Limited Partner and any officer, director, employee, agent, trustee, Affiliate
or stockholder of any Limited 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 in direct competition
with the Partnership or that are enhanced by the activities of the Partnership.
Neither the Partnership nor any Partners shall have any rights by virtue of this
Agreement in any business ventures of any Limited Partner or Assignee. Subject
to such agreements, none of the Limited Partners nor any other Person shall have
any rights by virtue of this Agreement or the partnership relationship
established hereby in any business ventures of any other Person, other than the
Limited Partners benefiting from the business conducted by the General Partner,
and such other Person shall have no obligation pursuant to this Agreement to
offer any interest in any such business ventures to the Partnership, any Limited
Partner or any such other Person, even if such opportunity is of a character
which, if presented to the Partnership, any Limited Partner or such other
Person, could be taken by such other Person.

               Section 8.4 Return of Capital

               Except pursuant to the rights of Redemption set forth in Section
8.6 and the Redemption and exchange rights set forth in Sections 17.5 and 17.8,

Capital Contribution, except to the extent of distributions made pursuant to
this Agreement or upon termination of the Partnership as provided herein. Except
as expressly set forth herein with respect to the rights, priorities and
preferences of the Preferred Limited Partners holding any series of Preferred
Units, no Limited Partner or

                                       49

<PAGE>   54
Assignee shall have priority over any other Limited Partner or Assignee either
as to the return of Capital Contributions, or as otherwise expressly provided in
this Agreement, as to profits, losses, distributions or credits.

               Section 8.5 Rights of Limited Partners Relating to the
Partnership

               A. In addition to other rights provided by this Agreement or by
the Act, and except as limited by Section 8.5.C, each Limited Partner shall have
the right, for a purpose reasonably related to such Limited Partner's interest
as a limited partner in the Partnership, upon written demand with a statement of
the purpose of such demand and at the Partnership's expense:

                (i)     to obtain a copy of the most recent annual and quarterly
                        reports filed with the Securities and Exchange
                        Commission by the General Partner pursuant to the
                        Exchange Act, and each communication sent to the
                        stockholders of the General Partner;

                (ii)    to obtain a copy of the Partnership's Federal, state and
                        local income tax returns for each Partnership Year;

                (iii)   to obtain a current list of the name and last known
                        business, residence or mailing address of each Partner;

                (iv)    to obtain a copy of this Agreement and the Certificate
                        and all amendments thereto, together with executed
                        copies of all powers of attorney pursuant to which this
                        Agreement, the Certificate and all amendments thereto
                        have been executed; and

                (v)     to obtain true and full information regarding the amount
                        of cash and a description and statement of any other
                        property or services contributed by each Partner and
                        which each Partner has agreed to contribute in the
                        future, and the date on which each became a Partner.

               B. The Partnership shall notify each Common Limited Partner in
writing of any adjustment made in the calculation of the REIT Shares Amount
within ten (10) Business Days of the date such change becomes effective.

               C. Notwithstanding any other provision of this Section 8.5, the
General Partner may keep confidential from the Limited Partners, for such period
of time as the General Partner determines in its sole and absolute discretion to
be reasonable, any information that (i) the General Partner believes to be in
the nature of trade secrets or other information the disclosure of which the
General Partner in good faith believes is not in the best interests of the
Partnership or (ii) the Partnership or the General Partner is required by law or
by agreements with unaffiliated third parties to keep confidential.

               Section 8.6 Common Limited Partner Redemption Rights

               A. On or after the date one year after the Effective Date, or on
or after such later date as expressly provided in an agreement entered into
between the Partnership and any Common Limited Partner, each Common Limited
Partner shall have the right (subject to the terms and conditions set forth
herein and in any other such agreement, as applicable) to require the
Partnership to redeem all or a portion of the Common Partnership Units held by
such Common Limited Partner (such Partnership Units being hereafter referred to
as "Tendered Units") in exchange for the Cash Amount (a "Redemption"); provided,
that the terms of such Common Partnership Units do not provide that such Common
Partnership Units are not entitled to a right of Redemption. Unless otherwise
expressly provided in this Agreement or a separate agreement entered into
between the Partnership and the holders of such Partnership Units, all Common
Partnership Units shall be entitled to a right of Redemption hereunder.
Notwithstanding the foregoing, a PLP shall not have the right to require the
Partnership to redeem, and the Partnership may not redeem, (i) a number of
Performance Units held by such PLP in excess of the Performance Amount; or (ii)
any Performance Units prior to the second anniversary of their issuance. Any
Redemption shall be exercised pursuant to a Notice of Redemption delivered to
the General Partner by the Common Limited Partner who is exercising the right
(the "Tendering Partner"). The Cash Amount shall be delivered as a certified
check payable to the Tendering Partner within ten (10) days of the Specified
Redemption Date in accordance with the instructions set forth in the Notice of
Redemption.

               B. Notwithstanding Section 8.6.A above, if a Common Limited
Partner has delivered to the General Partner a Notice of Redemption then the
General Partner may, in its sole and absolute discretion, (subject to the
limitations on ownership and transfer of REIT Shares set forth in Article IV.E
of the Charter) elect to acquire some or all of the Tendered Units from the
Tendering Partner in exchange for the REIT Shares Amount (as of the Specified
Redemption Date) and, if the General Partner so elects, the Tendering Partner
shall sell the Tendered Units to the General Partner in exchange for the REIT
Shares Amount. In such event, the Tendering Partner shall have no right to cause
the Partnership to redeem such Tendered Units. The General Partner shall
promptly give such Tendering Partner written notice of its election, and the
Tendering Partner may elect to withdraw its redemption request at any time prior
to the acceptance of the Cash Amount or REIT Shares Amount by such Tendering
Partner.

               C. The REIT Shares Amount, if applicable, shall be delivered as
duly authorized, validly issued, fully paid and nonassessable REIT Shares and,
if applicable, free of any pledge, lien, encumbrance or restriction, other than
those provided in the Charter, the Bylaws of the General Partner, the Securities
Act, relevant state securities or blue sky laws and any applicable registration
rights agreement with respect to such REIT Shares entered into by the Tendering
Partner. The REIT Shares Amount shall be registered in the name and otherwise
delivered as set forth in the Notice of Redemption. Notwithstanding any delay in
such delivery (but subject to Section 8.6.E below), the Tendering Partner shall
be deemed the owner of such REIT Shares for all purposes, including without
limitation, rights to vote or consent, and receive dividends, as of the
Specified Redemption Date.

                                       51

<PAGE>   56
               D. Each Common Limited Partner covenants and agrees with the
General Partner that all Tendered Units shall be delivered to the General
Partner free and clear of all liens, claims and encumbrances whatsoever and
should any such liens, claims and/or encumbrances exist or arise with respect to
such Tendered Units, the General Partner shall be under no obligation to acquire
the same. Each Common Limited Partner further agrees that, in the event any
state or local property transfer tax is payable as a result of the transfer of
its Tendered Units to the General Partner (or its designee), such Common Limited
Partner shall assume and pay such transfer tax.

               E. Notwithstanding the provisions of Sections 8.6.A, 8.6.B, 8.6.C
or any other provision of this Agreement, a Common Limited Partner (i) shall not
be entitled to effect a Redemption for cash or an exchange for REIT Shares to
the extent the ownership or right to acquire REIT Shares pursuant to such
exchange by such Partner on the Specified Redemption Date would cause such
Partner or any other Person, or, in the opinion of counsel selected by the
General Partner, may cause such Partner or any other Person, to violate the
restrictions on ownership and transfer of REIT Shares set forth in Article IV.E
of the Charter and (ii) shall have no rights under this Agreement to acquire
REIT Shares which would otherwise be prohibited under the Charter. To the extent
any attempted Redemption or exchange for REIT Shares would be in violation of
this Section 8.6.E, it shall be null and void ab initio and such Common Limited
Partner shall not acquire any rights or economic interest in the cash otherwise
payable upon such redemption or the REIT Shares otherwise issuable upon such
exchange.

               F. Notwithstanding anything herein to the contrary (but subject
to Section 8.6.E above), with respect to any Redemption or exchange for REIT
Shares pursuant to this Section 8.6:

                (i)     All Common Partnership Units acquired by the General
                        Partner pursuant thereto shall automatically, and
                        without further action required, be converted into and
                        deemed to be General Partner Interests comprised of the
                        same number and class of Common Partnership Units.

                (ii)    Without the consent of the General Partner, each Common
                        Limited Partner may not effect a Redemption for less
                        than 10,000 Partnership Units or, if the Common Limited
                        Partner holds less than 10,000 Partnership Units, all of
                        the Common Partnership Units held by such Common Limited
                        Partner.

                (iii)   Without the consent of the General Partner, each Common
                        Limited Partner may not effect a Redemption during the
                        period after the Partnership Record Date with respect to
                        a distribution and before the record date established by
                        the General Partner for a distribution to its common
                        stockholders of some or all of its portion of such
                        distribution.

                (iv)    The consummation of any Redemption or exchange for REIT
                        Shares shall be subject to the expiration or termination
                        of the applicable waiting period, if any, under the
                        Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
                        amended.

                                       52

<PAGE>   57
                (v)     Each Tendering Partner shall continue to own all Common
                        Partnership Units subject to any Redemption or exchange
                        for REIT Shares, and be treated as a Common Limited
                        Partner with respect to such Common Partnership Units
                        for all purposes of this Agreement, until such Common
                        Partnership Units are transferred to the General Partner
                        and paid for or exchanged as of the Specified Redemption
                        Date. Until a Specified Redemption Date, the Tendering
                        Partner shall have no rights as a stockholder of the
                        General Partner with respect to such Tendering Partner's
                        Common Partnership Units.

               G. In the event that the Partnership issues additional
Partnership Interests to any Additional Limited Partner pursuant to Section
4.3.C, the General Partner shall make such revisions to this Section 8.6 as it
determines are necessary to reflect the issuance of such additional Partnership
Interests.

principal office of the Partnership appropriate books and records with respect
to the Partnership's business, including without limitation, all books and
records necessary to provide to the Limited Partners any information, lists and
copies of documents required to be provided pursuant to Section 9.3. Any records
maintained by or on behalf of the Partnership in the regular course of its
business may be kept on, or be in the form of, punch cards, magnetic tape,
photographs, micrographics or any other information storage device; provided,
that the records so maintained are convertible into clearly legible written form

maintained, for financial and tax reporting purposes, on an accrual basis in
accordance with generally accepted accounting principles.

               Section 9.2 Fiscal Year

               A. As soon as practicable, but in no event later than one hundred
and five (105) days after the close of each Partnership Year, or such earlier
date as they are filed with the Securities and Exchange Commission, the General
Partner shall cause to be mailed to each Limited Partner as of the close of the
Partnership Year, an annual report containing financial statements of the
Partnership, or of the General Partner if such statements are prepared solely on
a consolidated basis with the General Partner, for such Partnership Year,
presented in accordance with generally accepted accounting principles, such
statements to be audited by a nationally recognized firm of independent public
accountants selected by the General Partner.

               B. As soon as practicable, but in no event later than forty-five
(45) days after the close of each calendar quarter (except the last calendar
quarter of each year), or such earlier date as they are filed with the
Securities and Exchange Commission, the General Partner shall cause to be mailed
to each Limited Partner as of the last day of the calendar quarter, a report
containing unaudited financial statements of the Partnership, or of the General
Partner, if such statements are prepared solely on a consolidated basis with the
General Partner, presented in accordance with the applicable law or regulation,
or as the General Partner determines to be appropriate.

               Section 9.4 Nondisclosure of Certain Information

               Notwithstanding the provisions of Sections 9.1 and 9.3, the
General Partner may keep confidential from the Limited Partners any information
that the General Partner believes to be in the nature of trade secrets or other
information the disclosure of which the General Partner in good faith believes
is not in the best interests of the Partnership or which the Partnership is
required by law or by agreements with unaffiliated third parties to keep
confidential.

                                   TAX MATTERS

               Section 10.1 Preparation of Tax Returns

               The General Partner shall arrange for the preparation and timely
filing of all returns of Partnership income, gains, deductions, losses and other
items required of the Partnership for Federal and state income tax purposes and
shall use all reasonable efforts to furnish, within ninety (90) days of the
close of each taxable year, the tax information reasonably required by Limited
Partners for Federal and state income tax reporting purposes. Each Limited
Partner shall promptly provide the General Partner with such information
relating to any Contributed Property contributed by such Limited Partner to the
Partnership.

               Section 10.2 Tax Elections

               Except as otherwise provided herein, the General Partner shall,
in its sole and absolute discretion, determine whether to make any available
election pursuant to the Code, including the election under Section 754 of the
Code. The General Partner shall have the right to seek to revoke any such
election (including without limitation, any election under Section 754 of the
Code) upon the General Partner's determination in its sole and absolute
discretion that such revocation is the best interests of the Partners.

               Section 10.3 Tax Matters Partner

               A. The General Partner shall be the "tax matters partner" of the
Partnership for Federal income tax purposes. Pursuant to Section 6223(c) of the
Code, upon receipt of notice from the IRS of the beginning of an administrative
proceeding with respect to the Partnership, the tax matters partner shall
furnish the IRS with the name, address and profit interest of each of the
Limited Partners and Assignees; provided, however, that such information is
provided to the Partnership by the Limited Partners and Assignees.

               B. The tax matters partner is authorized, but not required:

                (i)     to enter into any settlement with the IRS with respect
                        to any administrative or judicial proceedings for the
                        adjustment of Partnership items required to be taken
                        into account by a Partner for income tax purposes (such
                        administrative proceedings being referred to as a "tax
                        audit" and such judicial proceedings being referred to
                        as "judicial review"), and in the settlement agreement
                        the tax matters partner may expressly state that such
                        agreement shall bind all Partners, except that such
                        settlement agreement shall not bind any Partner (a) who
                        (within the time prescribed pursuant to the Code and
                        Regulations) files a statement with the IRS providing
                        that the tax matters partner shall not have the
                        authority to enter into a settlement agreement on behalf
                        of such Partner or (b) who is a "notice partner" (as
                        defined in Section 6231 of the Code) or a member of a
                        "notice group" (as defined in Section 6223(b)(2) of the
                        Code);

                (ii)    in the event that a notice of a final administrative
                        adjustment at the Partnership level of any item required
                        to be taken into account by a Partner for tax purposes
                        (a "final adjustment") is mailed to the tax matters
                        partner, to seek judicial review of such final
                        adjustment, including the filing of a petition for
                        readjustment with the Tax Court or the United States
                        Claims Court, or the filing of a complaint for refund
                        with the District Court of the United States for the
                        district in which the Partnership's principal place of
                        business is located;

                (iii)   to intervene in any action brought by any other Partner
                        for judicial review of a final adjustment;

                (iv)    to file a request for an administrative adjustment with
                        the IRS at any time and, if any part of such request is
                        not allowed by the IRS, to file an appropriate pleading
                        (petition or complaint) for judicial review with respect
                        to such request;

                (v)     to enter into an agreement with the IRS to extend the
                        period for assessing any tax which is attributable to
                        any item required to be taken into account by a Partner
                        for tax purposes, or an item affected by such item; and

                (vi)    to take any other action on behalf of the Partners of
                        the Partnership in connection with any tax audit or
                        judicial review proceeding to the extent permitted by
                        applicable law or regulations.

               The taking of any action and the incurring of any expense by the
tax matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of the General
Partner set forth in Section 7.7 shall be fully applicable to the tax matters
partner in its capacity as such.

                                       55

<PAGE>   60
               C. The tax matters partner shall receive no compensation for its
services. All third party costs and expenses incurred by the tax matters partner
in performing its duties as such (including legal and accounting fees) shall be
borne by the Partnership. Nothing herein shall be construed to restrict the
Partnership from engaging an accounting firm to assist the tax matters partner
in discharging its duties hereunder, so long as the compensation paid by the
Partnership for such services is reasonable.

               Section 10.4 Organizational Expenses

               The Partnership shall elect to deduct expenses, if any, incurred
by it in organizing the Partnership ratably over a sixty (60) month period as
provided in Section 709 of the Code.

               Section 10.5 Withholding

               Each Limited Partner hereby authorizes the Partnership to
withhold from or pay on behalf of or with respect to such Limited Partner any
amount of Federal, state, local, or foreign taxes that the General Partner
determines that the Partnership is required to withhold or pay with respect to
any amount distributable or allocable to such Limited Partner pursuant to this
Agreement, including, without limitation, any taxes required to be withheld or
paid by the Partnership pursuant to Sections 1441, 1442, 1445 or 1446 of the
Code. Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a loan by the Partnership to such Limited Partner, which loan shall
be repaid by such Limited Partner within fifteen (15) days after notice from the
General Partner that such payment must be made unless (i) the Partnership
withholds such payment from a distribution which would otherwise be made to the
Limited Partner or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. In the event that a Limited Partner
fails to pay any amounts owed to the Partnership pursuant to this Section 10.5
when due, the General Partner may, in its sole and absolute discretion, elect to
make the payment to the Partnership on behalf of such defaulting Limited
Partner, and in such event shall be deemed to have loaned such amount to such
defaulting Limited Partner and shall succeed to all rights and remedies of the
Partnership as against such defaulting Limited Partner (including, without
limitation, the right to receive distributions and the holding of a security
interest in such Limited Partner's Partnership Interest). Any amounts payable by
a Limited Partner hereunder shall bear interest at 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, plus two percentage points (but not
higher than the maximum lawful rate) from the date such amount is due (i.e., 15
days after demand) until such amount is paid in full. Each Limited Partner shall
take such actions as the Partnership or the General Partner shall request in
order to perfect or enforce the security interest created hereunder.

                            TRANSFERS AND WITHDRAWALS

               Section 11.1 Transfer

               A. The term "transfer," when used in this Article 11 with respect
to a Partnership Interest, shall be deemed to refer to a transaction by which
the General Partner purports to assign its General Partner Interest to another
Person or by which a Limited Partner purports to assign its Limited Partnership
Interest to another Person, and includes a sale, assignment, gift (outright or
in trust), pledge, encumbrance, hypothecation, mortgage, exchange or any other
disposition by law or otherwise. Except to the extent otherwise specified, the
term "transfer" when used in this Article 11 does not include any Redemption or
exchange for REIT Shares pursuant to Section 8.6 or any exchange for Series B
Preferred Shares pursuant to Section 17.8. No part of the interest of a Limited
Partner shall be subject to the claims of any creditor, any spouse for alimony
or support, or to legal process, and may not be voluntarily or involuntarily
alienated or encumbered, except as may be specifically provided for in this
Agreement.

               B. No Partnership Interest shall be transferred, in whole or in
part, except in accordance with the terms and conditions set forth in this
Article 11. Any transfer or purported transfer of a Partnership Interest not
made in accordance with this Article 11 shall be null and void ab initio unless
otherwise consented by the General Partner in its sole and absolute discretion.

               Section 11.2 Transfer of General Partner's Partnership Interest

               A. The General Partner shall not withdraw from the Partnership
and shall not transfer all or any portion of its interest in the Partnership
(whether by sale, statutory merger, consolidation, liquidation or otherwise)
without the Consent of the Limited Partners which may be given or withheld by
each such Limited Partner in its sole and absolute discretion, and only upon the
admission of a successor General Partner pursuant to Section 12.1; provided,
however, that, subject to Sections 11.2.B, 11.2.C, 11.2.D and 11.2.E, the
General Partner may withdraw from the Partnership and transfer all of its
interest upon the merger, consolidation or sale of substantially all of the
assets of the General Partner without the consent of any Limited Partners. Upon
any transfer of a Partnership Interest in accordance with the provisions of this
Section 11.2, the transferee shall become a substitute General Partner for all
purposes herein, and shall be vested with the powers and rights of the
transferor General Partner, and shall be liable for all obligations and
responsible for all duties of the General Partner, once such transferee has
executed such instruments as may be necessary to effectuate such admission and
to confirm the agreement of such transferee to be bound by all the terms and
provisions of this Agreement with respect to the Partnership Interest so
acquired. It is a condition to any transfer otherwise permitted hereunder that
the transferee assumes, by operation of law or express agreement, all of the
obligations of the transferor General Partner under this Agreement with respect
to such transferred Partnership Interest, and no such transfer (other than
pursuant to a statutory merger or consolidation wherein all obligations and
liabilities of the transferor General Partner are assumed by a successor
corporation by operation of law) shall relieve the transferor General Partner of
its

                                       57

<PAGE>   62
obligations under this Agreement without the Consent of the Partners, in their
reasonable discretion. In the event the General Partner withdraws from the
Partnership, or otherwise dissolves or terminates, or upon the Incapacity of the
General Partner, all of the remaining Partners may elect to continue the
Partnership business by selecting a substitute General Partner in accordance
with the Act.

               B. Neither the General Partner nor the Partnership may engage in
any merger, consolidation or other combination with or into another person, or
effect any reclassification, recapitalization or change of its outstanding
equity interests, and the General Partner may not sell all or substantially all
of its assets (each a "Termination Transaction") unless in connection with the
Termination Transaction all holders of Partnership Units either will receive, or
will have the right to elect to receive, for each Partnership Unit an amount of
cash, securities or other property equal to the product of the REIT Share Amount
and the greatest amount of cash, securities or other property paid to the holder
of one REIT Share in consideration of one REIT Share pursuant to the Termination
Transaction. If, in connection with the Termination Transaction, a purchase,
tender or exchange offer shall have been made to and accepted by the holders of
the outstanding REIT Shares, each holder of Partnership Units will receive, or
will have the right to elect to receive, the greatest amount of cash, securities
or other property which such holder would have received had it exercised its
rights to Redemption (as set forth in Section 8.6) and received REIT Shares in
exchange for its Partnership Units immediately prior to the expiration of such
purchase, tender or exchange offer and had thereupon accepted such purchase,
tender or exchange offer. The PLPs shall have the benefit of the foregoing
provisions with respect to all of their Performance Units, notwithstanding the
limitation set forth in Section 8.6.A on a PLPs ability to exercise its rights
to a Redemption.

               C. A Termination Transaction may also occur if the following
conditions are met: (i) substantially all of the assets directly or indirectly
owned by the surviving entity are held directly or indirectly by the Partnership
or another limited partnership or limited liability company which is the
survivor of a merger, consolidation or combination of assets with the
Partnership (in each case, the "Surviving Partnership"); (ii) the holders of
Partnership Units, including the holders of Performance Units issued or to be
issued, own a percentage interest of the Surviving Partnership based on the
relative fair market value of the net assets of the Partnership and the other
net assets of the Surviving Partnership immediately prior to the consummation of
such transaction; (iii) the rights, preferences and privileges of such holders
in the Surviving Partnership, including the holders of Performance Units issued
or to be issued, are at least as favorable as those in effect immediately prior
to the consummation of such transaction and as those applicable to any other
limited partners or non-managing members of the Surviving Partnership (except,
as to Performance Units, for such differences with Partnership Units regarding
liquidation, Redemption and exchange as are set forth herein); and (iv) such
rights of the Limited Partners, including the holders of Performance Units
issued or to be issued, include at least one of the following: (a) the right to
redeem their interests in the Surviving Partnership for the consideration
available to such persons pursuant to Section 11.2.B; or (b) the right to redeem
their Partnership Units for cash on terms equivalent to those in effect with
respect to their Partnership Units immediately prior to the consummation of such
transaction, or, if the ultimate controlling person of the Surviving Partnership
has publicly traded common equity securities,

                                       58

<PAGE>   63
such common equity securities, with an exchange ratio based on the determination
of relative fair market value of such securities and the REIT Shares.

               D. In connection with any transaction permitted by Section 11.2.B
or 11.2.C the determination of relative fair market values and rights,
preferences and privileges of the Limited Partners shall be reasonably
determined by the General Partner's Board of Directors as of the time of the
Termination Transaction and, to the extent applicable, the values shall be no
less favorable to the holders of Partnership Units than the relative values
reflected in the terms of the Termination Transaction.

               E. In the event of a Termination Transaction, the arrangements
with respect to Performance Units and Performance Shares will be equitably
adjusted to reflect the terms of the transaction, including, to the extent that
the REIT Shares are exchanged for consideration other than publicly traded
common equity, the transfer or release of remaining Performance Shares pursuant
to the Escrow Agreements, and resulting issuance of any Performance Units as set
forth in Section 4.3.F.

               Section 11.3 Limited Partners' Rights to Transfer

               A. Any Limited Partner may, at any time without the consent of
the General Partner, (i) transfer all or any portion of its Partnership Interest
to the General Partner, (ii) transfer all or any portion of its Partnership
Interest to an Affiliate controlled thereby or to an Immediate Family member,
subject to the provisions of Section 11.6, (iii) transfer all or any portion of
its Partnership Interest to a trust for the benefit of a charitable beneficiary
or to a charitable foundation, subject to the provisions of Section 11.6 and
(iv) subject to the provisions of Section 11.6, (a) pledge (a "Pledge") all or
any portion of its Partnership Interest to a lending institution, which is not
an Affiliate of such Limited Partner, as collateral or security for a bona fide
loan or other extension of credit, or (b) transfer such pledged Partnership
Interest to such lending institution in connection with the exercise of remedies
under such loan or extension of credit. In addition, each Limited Partner or
Assignee (resulting from a transfer made pursuant to clauses (i)-(iv) of the
preceding sentence) shall have the right to transfer all or any portion of its
Partnership Interest, subject to the provisions of Section 11.6 and the
satisfaction of each of the following conditions:

                (a)     General Partner Right of First Refusal. The transferring
                        Partner shall give written notice of the proposed
                        transfer to the General Partner, which notice shall
                        state (x) the identity of the proposed transferee and
                        (y) the amount and type of consideration proposed to be
                        received for the transferred Partnership Units. The
                        General Partner shall have ten (10) days upon which to
                        give the transferring Partner notice of its election to
                        acquire the Partnership Units on the proposed terms. If
                        it so elects, it shall purchase the Partnership Units on
                        such terms within ten (10) days after giving notice of
                        such election. If it does not so elect, the transferring
                        Partner may transfer such Partnership Units to a third
                        party, on economic terms no more favorable to the
                        transferee than the proposed terms, subject to the other
                        conditions of this Section 11.3.

                                       59

<PAGE>   64
                (b)     Qualified Transferee. Any transfer of a Partnership
                        Interest shall be made only to Qualified Transferees.

               It is a condition to any transfer otherwise permitted hereunder
that the transferee assumes by operation of law or express agreement all of the
obligations of the transferor Limited Partner under this Agreement with respect
to such transferred Partnership Interest and no such transfer (other than
pursuant to a statutory merger or consolidation wherein all obligations and
liabilities of the transferor Partner are assumed by a successor corporation by
operation of law) shall relieve the transferor Partner of its obligations under
this Agreement without the approval of the General Partner, in its reasonable
discretion. Notwithstanding the foregoing, any transferee of any transferred
Partnership Interest shall be subject to any and all ownership limitations
contained in the Charter, which may limit or restrict such transferee's ability
to exercise its Redemption rights or the exchange rights set forth in Section
17.8 and to the representations set forth in Section 3.4.D. Any transferee,
whether or not admitted as a Substituted Limited Partner, shall take subject to
the obligations of the transferor hereunder. Unless admitted as a Substituted
Limited Partner, no transferee, whether by a voluntary transfer, by operation of
law or otherwise, shall have any rights hereunder, other than the rights of an
Assignee as provided in Section 11.5.

               B. If a Limited Partner is subject to Incapacity, the executor,
administrator, trustee, committee, guardian, conservator, or receiver of such
Limited Partner's estate shall have all the rights of a Limited Partner, but not
more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate, and such power as the Incapacitated Limited
Partner possessed to transfer all or any part of his or its interest in the
Partnership. The Incapacity of a Limited Partner, in and of itself, shall not
dissolve or terminate the Partnership.

               C. The General Partner may prohibit any transfer otherwise
permitted under this Section 11.3 by a Limited Partner of his or her Partnership
Units if, in the opinion of legal counsel to the Partnership, such transfer
would require the filing of a registration statement under the Securities Act by
the Partnership or would otherwise violate any Federal or state securities laws
or regulations applicable to the Partnership or the Partnership Unit.

               D. No transfer by a Limited Partner of his or her Partnership
Units (including any Redemption or exchange for REIT Shares pursuant to Section
8.6, the Redemption or exchange rights set forth in Sections 17.5 and 17.8, or
any other acquisition of Common Units or Series B Preferred Partnership Units by
the General Partner or the Partnership) may be made to any person if (i) in the
opinion of legal counsel for the Partnership, it could result in the Partnership
being treated as an association taxable as a corporation or (ii) absent the
consent of the General Partner, which may be given or withheld in its sole and
absolute discretion, such transfer could be treated as effectuated through an
"established securities market" or a "secondary market (or the substantial
equivalent thereof)" within the meaning of Section 7704 of the Code.

               E. 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 Section
1.752-4(b) of the Regulations) to any lender to the Partnership whose loan
constitutes a Nonrecourse Liability,

                                       60

<PAGE>   65
without the consent of the General Partner, 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 redeem
or exchange for the REIT Shares Amount, or the specified amount of Series B
Preferred Shares, as the case may be, 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.

               F. No Limited Partner may withdraw from the Partnership except as
a result of transfer, Redemption or exchange of Partnership Units pursuant
hereto.

               G. No PLP (or any transferee described below) shall be entitled
to transfer any Performance Units prior to the second anniversary of their
issuance, without the consent of the General Partner, which may be given or
withheld in its sole discretion; provided, however, no such consent shall be
required under this Section 11.3.G (but subject to the other limitations of this
Article 11) for a transfer of all or a portion of such Performance Units to an
Affiliate, to Immediate Family Members, to a trust described in Section
11.3.A(iii), pursuant to a Pledge, or a transfer of such pledged units to such
lending institution in connection with the exercise of remedies under such loan
or extension of credit.

               Section 11.4 Substituted Limited Partners

               A. No Limited Partner shall have the right to substitute a
transferee as a Limited Partner in his or her place (including any transferee
permitted by Section 11.3 above). The General Partner shall, however, have the
right to consent to the admission of a permitted transferee of the interest of a
Limited Partner, as a Substituted Limited Partner, pursuant to this Section
11.4, which consent may be given or withheld by the General Partner in its sole
and absolute discretion. The General Partner's failure or refusal to permit a
transferee of any such interests to become a Substituted Limited Partner shall
not give rise to any cause of action against the Partnership or any Partner.

               B. A transferee who has been admitted as a Substituted Limited
Partner in accordance with this Article 11 shall have all the rights and powers
and be subject to all the restrictions and liabilities of a Limited Partner
under this Agreement. The admission of any transferee as a Substituted Limited
Partner shall be subject to the transferee executing and delivering to the
Partnership an acceptance of all of the terms and conditions of this Agreement
(including, without limitation, the provisions of Section 2.4 and such other
documents or instruments as may be required to effect the admission, each in
form and substance satisfactory to the General Partner) and the acknowledgment
by such transferee that each of the representations and warranties set forth in
Section 3.4 are true and correct with respect to such transferee as of the date
of the transfer of the Partnership Interest to such transferee and will continue
to be true to the extent required by such representations and warranties.

               C. Upon the admission of a Substituted Limited Partner, the
General Partner shall amend Exhibit A to reflect the name, address, number of
Partnership Units, and Percentage Interest of such Substituted Limited Partner
and to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.

                                       61

               Section 11.5 Assignees

               If the General Partner, in its sole and absolute discretion, does
not consent to the admission of any permitted transferee under Section 11.3 as a
Substituted Limited Partner, as described in Section 11.4, such transferee shall
be considered an Assignee for purposes of this Agreement. An Assignee shall be
entitled to all the rights of an assignee of a limited partnership interest
under the Act, including the right to receive distributions from the Partnership
and the share of Net Income, Net Losses, gain and loss attributable to the
Partnership Units assigned to such transferee, the rights to transfer the
Partnership Units provided in this Article 11, the right of Redemption provided
in Section 8.6, and the right of exchange for Series B Preferred Shares set
forth in Section 17.8, but shall not be deemed to be a holder of Partnership
Units for any other purpose under this Agreement, and shall not be entitled to
effect a Consent with respect to such Partnership Units on any matter presented
to the Limited Partners for approval (such Consent remaining with the transferor
Limited Partner). In the event any such transferee desires to make a further
assignment of any such Partnership Units, such transferee shall be subject to
all the provisions of this Article 11 to the same extent and in the same manner
as any Limited Partner desiring to make an assignment of Partnership Units.
Notwithstanding anything contained in this Agreement to the contrary, as a
condition to becoming an Assignee, any prospective Assignee must first execute
and deliver to the Partnership an acknowledgment that each of the
representations and warranties set forth in Section 3.4 hereof are true and
correct with respect to such prospective Assignee as of the date of the
prospective assignment of the Partnership Interest to such prospective Assignee
and will continue to be true to the extent required by such representations or
warranties.

               Section 11.6 General Provisions

               A. No Limited Partner may withdraw from the Partnership other
than as a result of (i) a permitted transfer of all of such Limited Partner's
Partnership Units in accordance with this Article 11 and the transferee(s) of
such Units being admitted to the Partnership as a Substituted Limited Partner(s)
or (ii) pursuant to the exercise of its right of Redemption of all of such
Limited Partner's Partnership Units under Section 8.6 or its right of Redemption
or exchange of all of such Limited Partner's Series B Preferred Units under
Section 17.8.

               B. Any Limited Partner who shall transfer all of such Limited
Partner's Partnership Units in a transfer permitted pursuant to this Article 11
where such transferee was admitted as a Substituted Limited Partner or pursuant
to the exercise of its rights of Redemption of all of such Limited Partner's
Partnership Units under Section 8.6 or its right of Redemption or exchange of
all of such Limited Partner's Series B Preferred Units under Section 17.8, shall
cease to be a Limited Partner.

               C. Transfers pursuant to this Article 11 may only be made
effective on the last day of the month set forth on the written instrument of
transfer, unless the General Partner otherwise agrees.

               D. If any Partnership Interest is transferred, assigned or
redeemed during any quarterly segment of the Partnership's fiscal year in
compliance with the provisions of this Article 11 or transferred or redeemed
pursuant to Sections 8.6 or 17.5, on any day other than the

                                       62

<PAGE>   67
first day of a Partnership Year, then Net Income, Net Losses, each item thereof
and all other items attributable to such Partnership Interest for such fiscal
year shall be divided and allocated between the transferor Partner and the
transferee Partner by taking into account their varying interests during the
fiscal year in accordance with Section 706(d) of the Code, using the interim
closing of the books method. Except as otherwise required by Section 706(d) of
the Code or as otherwise specified in this Agreement or as otherwise determined
by the General Partner (to the extent consistent with Section 706(d) of the
Code), solely for purposes of making such allocations, each of such items for
the calendar month in which the transfer, assignment or redemption occurs shall
be allocated among all the Partners and Assignees in a manner determined by the
General Partner in its sole discretion.

               E. In addition to any other restrictions on transfer herein
contained, including without limitation the provisions of this Article 11 and
Section 2.6, in no event may any transfer or assignment of a Partnership
Interest by any Partner (including by way of a Redemption or exchange for Series
B Preferred Shares, or any other acquisition of Common Units or Series B
Preferred Units by the Partnership or the General Partner) be made (i) to any
person or entity who lacks the legal right, power or capacity to own a
Partnership Interest; (ii) in violation of applicable law; (iii) except with the
consent of the General Partner, which may be given or withheld in its sole and
absolute discretion, of any component portion of a Partnership Interest, such as
the Capital Account, or rights to distributions, separate and apart from all
other components of a Partnership Interest; (iv) except with the consent of the
General Partner, which may be given or withheld in its sole and absolute
discretion, if in the opinion of legal counsel to the Partnership such transfer
would cause a termination of the Partnership for Federal or state income tax
purposes (except as a result of the Redemption or exchange for REIT Shares, and
a Redemption or exchange for Preferred Shares or cash pursuant to Sections 17.5
and 17.8, of all Partnership Units held by all Limited Partners or pursuant to a
Termination Transaction expressly permitted under Section 11.2); (v) if in the
opinion of counsel to the Partnership such transfer would cause the Partnership
to cease to be classified as a partnership for Federal or state income tax
purposes (except as a result of the Redemption or exchange for REIT Shares and a
Redemption or exchange for Preferred Shares pursuant to Sections 17.5 and 17.8
of all Partnership Units held by all Limited Partners); (vi) if such transfer
would cause the Partnership to become, with respect to any employee benefit plan
subject to Title I of ERISA, a "party-in-interest" (as defined in Section 3(14)
of ERISA) or a "disqualified person" (as defined in Section 4975(c) of the
Code); (vii) if such transfer would, in the opinion of counsel to the
Partnership, cause any portion of the assets of the Partnership to constitute
assets of any employee benefit plan pursuant to Department of Labor Regulations
Section 2510.2-101; (viii) if such transfer requires the registration of such
Partnership Interest or requires the registration of the exchange of such
Partnership Interests for any capital stock pursuant to any applicable Federal
or state securities laws; (ix) except with the consent of the General Partner,
which may be given or withheld in its sole and absolute discretion, if 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 or such transfer causes the Partnership to become a
"Publicly Traded Partnership," as such term is defined in Sections 469(k)(2) or
7704(b) of the Code; (x) if such transfer subjects the Partnership to be
regulated under the Investment Company Act of 1940, the Investment Advisors Act
of 1940 or the Employee Retirement Income Security Act of 1974, each as amended;
(xi) if the transferee or assignee of such Partnership Interest is

                                       63

<PAGE>   68
unable to make the representations set forth in Section 3.4.D or such transfer
could otherwise adversely affect the ability of the General Partner to remain
qualified as a REIT; or (xii) if in the opinion of legal counsel for the
Partnership such transfer would adversely affect the ability of the General
Partner to continue to qualify as a REIT or, except with the consent of the
General Partner, which may be given or withheld in its sole and absolute
discretion, subject the General Partner to any additional taxes under Section
857 or Section 4981 of the Code.

               F. The General Partner shall monitor the transfers of interests
in the Partnership (including any acquisition of Common Units or Series B
Preferred Partnership Units by the Partnership or the General Partner) to
determine (i) if such interests are being traded on an "established securities
market" or a "secondary market (or the substantial equivalent thereof)" within
the meaning of Section 7704 of the Code and (ii) whether such transfers of
interests would result in the Partnership being unable to qualify for at least
one of the "safe harbors" set forth in Regulations Section 1.7704-1 (or such
other applicable guidance subsequently published by the IRS setting forth safe
harbors under which interests will not be treated as "readily tradable on a
secondary market (or the substantial equivalent thereof)" within the meaning of
Section 7704 of the Code) (the "Safe Harbors"). The General Partner shall have
authority (but shall not be required to) to take any steps it determines are
necessary or appropriate in its sole and absolute discretion to prevent any
trading of interests which could cause the Partnership to become a "publicly
traded partnership," or any recognition by the Partnership of such transfers, or
to insure that at least one of the Safe Harbors is met.

                                   ARTICLE 12.
                              ADMISSION OF PARTNERS

               Section 12.1 Admission of Successor General Partner

               A successor to all of the General Partner's General Partner
Interest pursuant to Section 11.2 who is proposed to be admitted as a successor
General Partner shall be admitted to the Partnership as the General Partner,
effective upon such transfer. Any such transferee shall carry on the business of
the Partnership without dissolution. In each case, the admission shall be
subject to the successor General Partner executing and delivering to the
Partnership an acceptance of all of the terms and conditions of this Agreement
and such other documents or instruments as may be required to effect the
admission. In the case of such admission on any day other than the first day of
a Partnership Year, all items attributable to the General Partner Interest for
such Partnership Year shall be allocated between the transferring General
Partner and such successor as provided in Article 11.

               Section 12.2 Admission of Additional Limited Partners

               A. A Person who makes a Capital Contribution to the Partnership
in accordance with this Agreement shall be admitted to the Partnership as an
Additional Limited Partner only upon furnishing to the General Partner (i)
evidence of acceptance in form satisfactory to the General Partner of all of the
terms and conditions of this Agreement, including, without limitation, the power
of attorney granted in Section 2.4 and (ii) such other documents or instruments
as may be required in the discretion of the General Partner in order to effect
such Person's admission as an Additional Limited Partner.

                                       64

<PAGE>   69
               B. Notwithstanding anything to the contrary in this Section 12.2,
no Person shall be admitted as an Additional Limited Partner without the consent
of the General Partner, which consent may be given or withheld in the General
Partner's sole and absolute discretion. The admission of any Person as an
Additional Limited Partner shall become effective on the date upon which the
name of such Person is recorded on the books and records of the Partnership,
following the receipt of the Capital Contribution in respect of such Limited
Partner, the documents set forth in this Section 12.2.A and the consent of the
General Partner to such admission. If any Additional Limited Partner is admitted
to the Partnership on any day other than the first day of a Partnership Year,
then Net Income, Net Losses, each item thereof and all other items allocable
among Partners and Assignees for such Partnership Year shall be allocated among
such Limited Partner and all other Partners and Assignees by taking into account
their varying interests during the Partnership Year in accordance with Section
706(d) of the Code, using the interim closing of the books method. Solely for
purposes of making such allocations, each of such items for the calendar month
in which an admission of an Additional Limited Partner occurs shall be allocated
among all the Partners and Assignees, including such Additional Limited Partner,
in a manner determined by the General Partner in its sole discretion.

               Section 12.3 Amendment of Agreement and Certificate of Limited
Partnership

               For the admission to the Partnership of any Partner, the General
Partner shall take all steps necessary and appropriate under the Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 2.4.

                                   ARTICLE 13.
                           DISSOLUTION AND LIQUIDATION

               Section 13.1 Dissolution

               The Partnership shall not be dissolved by the admission of
Substituted Limited Partners or Additional Limited Partners or by the admission
of a successor General Partner in accordance with the terms of this Agreement.
Upon the withdrawal of the General Partner, any successor General Partner
(selected as described in Section 13.1.B below) shall continue the business of
the Partnership. The Partnership shall dissolve, and its affairs shall be wound
up, upon the first to occur of any of the following ("Liquidating Events"):

               A. the expiration of its term as provided in Section 2.5;

               B. an event of withdrawal of the General Partner, as defined in
the Act, unless, within ninety (90) days after the withdrawal, all of the
remaining Partners agree in writing, in their sole and absolute discretion, to
continue the business of the Partnership and to the appointment, effective as of
the date of withdrawal, of a substitute General Partner;

                                       65

<PAGE>   70
               C. prior to December 31, 2096, an election to dissolve the
Partnership made by the General Partner with the consent of Limited Partners who
hold ninety percent (90%) of the outstanding Units held by Limited Partners;

               D. subject to the provisions of Section 7.3.C, an election to
dissolve the Partnership made by the General Partner in its sole and absolute
discretion;

               E. entry of a decree of judicial dissolution of the Partnership
pursuant to the provisions of the Act;

               F. the sale or disposition of all or substantially all of the
assets and properties of the Partnership;

               G. final and non-appealable judgment is entered by a court of
competent jurisdiction ruling that the General Partner is bankrupt or insolvent,
or a final and non-appealable order for relief is entered by a court with
appropriate jurisdiction against the General Partner, in each case under any
Federal or state bankruptcy or insolvency laws as now or hereafter in effect,
unless prior to or at the time of the entry of such order or judgment a Majority
in Interest of the remaining Limited Partners Consent in writing to continue the
business of the Partnership and to the appointment, effective as of a date prior
to the date of such order or judgment, of a substitute General Partner; or

               H. the Redemption or exchange for REIT Shares or Series B
Preferred Shares of all Partnership Units (other than those of the General
Partner) pursuant to this Agreement.

               Section 13.2 Winding Up

               A. Upon the occurrence of a Liquidating Event, the Partnership
shall continue solely for the purposes of winding up its affairs in an orderly
manner, liquidating its assets, and satisfying the claims of its creditors and
Partners. No Partner shall take any action that is inconsistent with, or not
necessary to or appropriate for, the winding up of the Partnership's business
and affairs. The General Partner (or, in the event there is no remaining General
Partner, any Person elected by a Majority in Interest of the Limited Partners
(the "Liquidator")) shall be responsible for overseeing the winding up and
dissolution of the Partnership and shall take full account of the Partnership's
liabilities and assets and the Partnership property shall be liquidated as
promptly as is consistent with obtaining the fair value thereof, and the
proceeds therefrom (which may, to the extent determined by the General Partner,
include shares of stock of the General Partner) shall be applied and distributed
in the following order:

                (i)     First, to the payment and discharge of all of the
                        Partnership's debts and liabilities to creditors other
                        than the Partners;

                (ii)    Second, to the payment and discharge of all of the
                        Partnership's debts and liabilities to the General
                        Partner;

                (iii)   Third, to the payment and discharge of all of the
                        Partnership's debts and liabilities to the other
                        Partners; and

                                       66

<PAGE>   71
                (iv)    The balance, if any, to the Partners in accordance with
                        their Capital Account balances determined after giving
                        effect to all contributions and distributions for all
                        periods, and after taking into account all Capital
                        Account adjustments for the Partnership taxable year
                        during which the liquidation occurs (other than those
                        made as a result of the liquidating distribution set
                        forth in this Section 13.2.A(iv)).

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13 other than reimbursement of its
expenses as provided in Section 7.4.

               B. Notwithstanding the provisions of Section 13.2.A which require
liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership
the Liquidator determines that an immediate sale of part or all of the
Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2.A, undivided interests in such
Partnership assets as the Liquidator deems not suitable for liquidation. Any
such distributions in kind shall be made only if, in the good faith judgment of
the Liquidator, such distributions in kind are in the best interest of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

               C. The Partnership shall be terminated when any notes received in
connection with any such sale or disposition referenced in Section 13.1.E above,
or in connection with the liquidation of the Partnership have been paid and all
of the cash or property available for application and distribution under this
Agreement have been applied and distributed in accordance with this Agreement.

               Section 13.3 Compliance with Timing Requirements of Regulations

               In the event the Partnership is "liquidated" within the meaning
of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made
pursuant to this Article 13 to the General Partner and Limited Partners who have
positive Capital Accounts in compliance with Regulations Section
1.704-1(b)(2)(ii)(b)(2). If any Partner has a deficit balance in his or her
Capital Account (after giving effect to all contributions, distributions and
allocations for the taxable years, including the year during which such
liquidation occurs), such Partner shall have no obligation to make any
contribution to the capital of the Partnership with respect to such deficit, and
such deficit shall not be considered a debt owed to the Partnership or to any
other Person for any purpose whatsoever, except to the extent otherwise agreed
to by such Partner and the General Partner. In the discretion of the Liquidator
or the General Partner, a pro rata portion of the distributions that would
otherwise be made to the General Partner and Limited Partners pursuant to this
Article 13 may be:

                                       67

<PAGE>   72
               A. distributed to a trust established for the benefit of the
General Partner and Limited Partners for the purposes of liquidating Partnership
assets, collecting amounts owed to the Partnership, and paying any contingent or
unforeseen liabilities or obligations of the Partnership or of the General
Partner arising out of or in connection with the Partnership. The assets of any
such trust shall be distributed to the General Partner and Limited Partners from
time to time, in the reasonable discretion of the Liquidator or the General
Partner, in the same proportions and the amount distributed to such trust by the
Partnership would otherwise have been distributed to the General Partner and
Limited Partners pursuant to this Agreement; or

               B. withheld to establish any reserves deemed necessary or
appropriate for any contingent or unforeseen liabilities or obligations of the
Partnership; and to reflect the unrealized portion of any installment
obligations owed to the Partnership; provided that, such withheld amounts shall
be distributed to the General Partner and Limited Partners as soon as
practicable.

               Section 13.4 Deemed Distribution and Recontribution

               Notwithstanding any other provision of this Article 13, in the
event the Partnership is liquidated within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership's
property shall not be liquidated, the Partnership's liabilities shall not be
paid or discharged, and the Partnership's affairs shall not be wound up.
Instead, the Partnership shall be deemed to have distributed the Partnership
property in kind to the General Partner and Limited Partners, who shall be
deemed to have assumed and taken such property subject to all Partnership
liabilities, all in accordance with their respective Capital Accounts.
Immediately thereafter, the General Partner and Limited Partners shall be deemed
to have recontributed the Partnership property in kind to the Partnership, which
shall be deemed to have assumed and taken such property subject to all such
liabilities.

               Section 13.5 Rights of Limited Partners

               Except as otherwise provided in this Agreement, each Limited
Partner shall look solely to the assets of the Partnership for the return of his
Capital Contribution and shall have no right or power to demand or receive
property from the General Partner. Except as expressly set forth herein with
respect to the rights, priorities and preferences of the Preferred Limited
Partners holding any series of Preferred Units, no Limited Partner shall have
priority over any other Limited Partner as to the return of his Capital
Contributions, distributions or allocations.

               Section 13.6 Notice of Dissolution

               In the event a Liquidating Event occurs or an event occurs that
would, but for provisions of Section 13.1, result in a dissolution of the
Partnership, the General Partner shall, within thirty (30) days thereafter,
provide written notice thereof to each of the Partners and to all other parties
with whom the Partnership regularly conducts business (as determined in the
discretion of the General Partner) and shall publish notice thereof in a
newspaper of general circulation in each place in which the Partnership
regularly conducts business (as determined in the discretion of the General
Partner).

               Section 13.7 Cancellation of Certificate of Limited Partnership

                                       68

<PAGE>   73
               Upon the completion of the liquidation of the Partnership cash
and property as provided in Section 13.2, the Partnership shall be terminated

                  AMENDMENT OF PARTNERSHIP AGREEMENT; CONSENTS

               Section 14.1 Amendments

               A. The actions requiring consent or approval of the Partners or
of the Limited Partners pursuant to this Agreement, including Section 7.3, or
otherwise pursuant to applicable law, are subject to the procedures in this
Article 14.

               B. Amendments to this Agreement requiring the consent or approval
of Limited Partners may be proposed by the General Partner or by Limited
Partners holding twenty-five percent (25%) or more of the Partnership Interests
held by Limited Partners. Following such proposal, the General Partner shall
submit any proposed amendment to the Partners or of the Limited Partners, as
applicable. The General Partner shall seek the written consent or approval of
the Partners or of the Limited Partners on the proposed amendment or shall call
a meeting to vote thereon and to transact any other business that it may deem
appropriate. For purposes of obtaining a written consent, the General Partner
may require a response within a reasonable specified time, but not less than
fifteen (15) days, and failure to respond in such time period shall constitute a
consent which is consistent with the General Partner's recommendation (if so
recommended); provided that, an action shall become effective at such time as
requisite consents are received even if prior to such specified time.

               Section 14.2 Action by the Partners

               A. Meetings of the Partners may be called by the General Partner
and shall be called upon the receipt by the General Partner of a written request
by Limited Partners holding twenty-five percent (25%) or more of the Partnership
Interests held by the Limited Partners. The call shall state the nature of the
business to be transacted. Notice of any such meeting shall be given to all
Partners not less than seven days nor more than thirty (30) days prior to the
date of such meeting. Partners may vote in person or by proxy at such meeting.
Whenever the vote of

                                       69

<PAGE>   74
the Percentage Interests of the Partners, or the Consent of the Partners or
Consent of the Limited Partners is permitted or required under this Agreement,
such vote or Consent may be given at a meeting of Partners or may be given in
accordance with the procedure prescribed in Section 14.1.

               B. Any action required or permitted to be taken at a meeting of
the Partners may be taken without a meeting if a written consent setting forth
the action so taken is signed by the Percentage Interests as is expressly
required by this Agreement for the action in question. Such consent may be in
one instrument or in several instruments, and shall have the same force and
effect as a vote of the Percentage Interests of the Partners (expressly required
by this Agreement). Such consent shall be filed with the General Partner. An
action so taken shall be deemed to have been taken at a meeting held on the
effective date so certified.

               C. Each Limited Partner may authorize any Person or Persons to
act for him by proxy on all matters in which a Limited Partner is entitled to
participate, including waiving notice of any meeting, or voting or participating
at a meeting. Every proxy must be signed by the Limited Partner or his
attorney-in-fact. No proxy shall be valid after the expiration of eleven (11)
months from the date thereof unless otherwise provided in the proxy. Every proxy
shall be revocable at the pleasure of the Limited Partner executing it.

               D. Each meeting of Partners shall be conducted by the General
Partner or such other Person as the General Partner may appoint pursuant to such
rules for the conduct of the meeting as the General Partner or such other Person
deems appropriate.

               E. On matters on which Limited Partners are entitled to vote,
each Limited Partner shall have a vote equal to the number of Partnership Units
held.

               Section 15.11 Limitation to Preserve REIT Status

               To the extent that any amount paid or credited to the General
Partner or its officers, directors, employees or agents pursuant to Section 7.4
or 7.7 would constitute gross income to the General Partner for purposes of
Sections 856(c)(2) or 856(c)(3) of the Code (a "General Partner Payment") then,
notwithstanding any other provision of this Agreement, the amount of such
General Partner Payments for any fiscal year shall not exceed the lesser of:

                (i)     an amount equal to the excess, if any, of (a) 4.17% of
                        the General Partner's total gross income (but not
                        including the amount of any General Partner Payments)
                        for the fiscal year which is described in subsections
                        (A) through (H) of Section 856(c)(2) of the Code over
                        (b) the amount of gross income (within the meaning of
                        Section 856(c)(2) of the Code) derived by the General
                        Partner from sources other than those described in
                        subsections (A) through (H) of Section 856(c)(2) of the
                        Code (but not including the amount of any General
                        Partner Payments); or

                (ii)    an amount equal to the excess, if any, of (a) 25% of the
                        General Partner's total gross income (but not including
                        the amount of any General Partner Payments) for the
                        fiscal year which is described in subsections (A)
                        through (I) of Section 856(c)(3) of the Code over (b)
                        the amount of gross income (within the meaning of
                        Section 856(c)(3) of the Code) derived by the General
                        Partner from sources other than those described in
                        subsections (A) through (I) of Section 856(c)(3) of the
                        Code (but not including the amount of any General
                        Partner Payments);

provided, however, that General Partner Payments in excess of the amounts set
forth in subparagraphs (i) and (ii) above may be made if the General Partner, as
a condition precedent, obtains an opinion of tax counsel that the receipt of
such excess amounts would not adversely affect the General Partner's ability to
qualify as a REIT. To the extent General Partner Payments may not be made in a
year due to the foregoing limitations, such General Partner Payments shall carry
over and be treated as arising in the following year; provided, however, that
such amounts shall not carry over for more than five years, and if not paid
within such five year period, shall expire; provided, further, that (a) as
General Partner Payments are made, such payments shall be applied first to carry
over amounts outstanding, if any and (b) with respect to carry over amounts for
more than one Partnership Year, such payments shall be applied to the earliest
Partnership Year first.

               Section 15.12 Entire Agreement

hereto as to rights and obligations in respect of the Units held by the Limited
Partners who are parties thereto, or their permitted transferees) contains the
entire understanding and agreement among the Partners with respect to the
subject matter hereof and supersedes any other prior written or oral
understandings or agreements among them with respect thereto.

               Section 15.13 No Rights as Stockholders

               Nothing contained in this Agreement shall be construed as
conferring upon the holders of Partnership Units any rights whatsoever as
stockholders of the General Partner, including without limitation any right to
receive dividends or other distributions made to stockholders of the General
Partner or to vote or to consent or to receive notice as stockholders in respect
of any meeting of stockholders for the election of directors of the General
Partner or any other matter.

                                   ARTICLE 16.
                            SERIES A PREFERRED UNITS

               Section 16.1 Designation and Number

               A series of Partnership Units in the Partnership designated as
the 8 1/2% Series A Cumulative Redeemable Preferred Units (the "Series A
Preferred Units") is hereby established. The number of Series A Preferred Units
shall be 4,600,000.

               Section 16.2 Section 16.2 Ranking

               The Series A Preferred Units shall, with respect to distribution
rights and rights upon voluntary or involuntary liquidation, winding up or
dissolution of the Partnership, rank (i) senior to the Common Units and to all
Partnership Units the terms of which provide that such Partnership Units shall
rank junior to the Series A Preferred Units; (ii) on a parity with the Series B
Preferred Units and all other Parity Preferred Units; and (iii) junior to all
Partnership Units which rank senior to the Series A Preferred Units.

               Section 16.3 Section 16.3. Distributions

               A. Payments of Distribution. Subject to the rights of holders of
Parity Preferred Units (including Series B Preferred Units) as to the payment of
distributions, pursuant to Section 5.1 and Section 17.3.A hereof, the General
Partner, as holder of the Series A Preferred Units, will be entitled to receive,
when, as and if declared by the Partnership acting through the General Partner,
out of Available Cash, cumulative preferential cash distributions in an amount
equal to the Series A Priority Return. Such distributions will be payable (A)
quarterly in arrears, on the 15th day of January, April, July and October of
each year and (B) in the event of a redemption of Series A Preferred Units, on
the redemption date (each a "Series A Preferred Unit Distribution Payment
Date"), commencing on the first of such payment dates to occur following their
original date of issuance. If any date on which distributions are to be made on
the Series A Preferred Units is not a Business Day, then payment of the
distribution to be made on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.

               B. No Distributions in Contravention of Agreements. No
distribution on the Series A Preferred Units shall be authorized by the General
Partner or made or set apart for payment by the Partnership at such time as the
terms and provisions of any agreement of the

                                       73

<PAGE>   78
Partnership or the General Partner, including any agreement relating to
indebtedness, prohibits such declaration, payment or setting apart for payment
or provides that such declaration, payment or setting apart for payment would
constitute a breach thereof, or a default thereunder, or if such declaration or
payment shall be restricted or prohibited by law.

               C. Priority as to Distributions. (i) Except to the extent set
forth in Section 16.3.C(ii), so long as any Series A Preferred Units are
outstanding, no distribution of cash or other property shall be authorized,
declared, paid or set apart for payment on or with respect to any class or
series of Partnership Interest represented by Junior Units, nor shall any Junior
Units or Parity Preferred Units (including the Series B Preferred Units) be
redeemed, purchased or otherwise acquired for any consideration (or any monies
be paid to or made available for a sinking fund for the redemption of any such
Junior Units or Parity Preferred Units) by the Partnership (except by conversion
into or exchange for other Junior Units or Parity Preferred Units) unless, in
each case, full cumulative distributions have been or contemporaneously are
authorized and paid or authorized and a sum sufficient for the payment thereof
set apart for such payment on the Series A Preferred Units for all past
distribution periods and the current distribution period. The foregoing sentence
will not prohibit (a) distributions payable solely in Junior Units, (b) the
exchange of Junior Units or Parity Preferred Units (including the Series B
Preferred Units) into Partnership Interests of the Partnership ranking junior to
the Series A Preferred Units as to distributions, or (c) the redemption of
Partnership Interests corresponding to Series A Preferred Shares, Parity
Preferred Stock (including Series B Preferred Shares) with respect to
distributions or Junior Stock to be purchased by the General Partner pursuant to
the Charter to preserve the General Partner's status as a real estate investment
trust, provided that such redemption shall be upon the same terms as the
corresponding stock purchase pursuant to the Charter.

               (ii) So long as distributions have not been paid in full (or a
sum sufficient for such full payment is not so set apart) upon the Series A
Preferred Units and any other Parity Preferred Units (including the Series B
Preferred Units), all distributions authorized and declared on the Series A
Preferred Units and all classes or series of outstanding Parity Preferred Units
(including the Series B Preferred Units) shall be authorized and declared pro
rata so that the amount of distributions authorized and declared per Series A
Preferred Unit and such other classes or series of Parity Preferred Units shall
in all cases bear to each other the same ratio that accrued distributions per
Series A Preferred Unit and such other classes or series of Parity Preferred
Units (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Units do not have cumulative distribution rights) bear to each other.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distributions or payments on Series A Preferred Units which may be in
arrears.

               D. No Further Rights. The General Partner, as holder of the
Series A Preferred Units, shall not be entitled to any distributions, whether
payable in cash, other property or otherwise, in excess of the full cumulative
distributions described herein. Any distribution payment made on the Series A
Preferred Units shall first be credited against the earliest accrued but unpaid
distribution due with respect to such Series A Preferred Units which remain
payable.

               Section 16.4 Liquidation Proceeds

               A. Upon voluntary or involuntary liquidation, dissolution or
winding-up of the Partnership, distributions on the Series A Preferred Units
shall be made in accordance with Article 13 of this Agreement.

               B. Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by the General Partner
pursuant to Section 13.6 hereof.

               C. No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, the General Partner, as
holder of the Series A Preferred Units, will have no right or claim to any of
the remaining assets of the Partnership.

               D. Consolidation, Merger or Certain Other Transactions. None of a
consolidation or merger of the Partnership with or into another entity, a merger
of another entity with or into the Partnership, or a sale, lease, transfer or
conveyance of all or substantially all of the Partnership's property or business
shall be considered a liquidation, dissolution or winding up of the Partnership.

               Section 16.5 Redemption

               A. Redemption. The Series A Preferred Units may not be redeemed
prior to July 27, 2003. If, on or after such date, the General Partner elects to
redeem any of the Series A Preferred Shares, the Partnership shall, on the date
set for redemption of such Series A Preferred Shares, redeem the number of
Series A Preferred Units equal to the number of Series A Preferred Shares for
which the General Partner has given notice of redemption pursuant to Section 5
of Article Third of the Series A Articles Supplementary, at a redemption price,
payable in cash, equal to the product of (i) the number of Series A Preferred
Units being redeemed, and (ii) the sum of $25 and the Preferred Distribution
Shortfall per Series A Preferred Unit, if any.

               B. Limitation on Redemption. The Redemption Price of the Series A
Preferred Units (other than the portion thereof consisting of accumulated but
unpaid distributions) is payable solely out of the sale proceeds of capital
stock of the General Partner, which will be contributed by the General Partner
to the Partnership as an additional capital contribution, or out of the sale of
limited partner interests in the Partnership and from no other source. For
purposes of the preceding sentence, "capital stock" means any equity securities
(including Common Stock and Preferred Stock (as such terms are defined in the
Charter)), depository shares, interests, participation or other ownership
interests (however designated) and any rights (other than debt securities
convertible into or exchangeable for equity securities) or options to purchase
any of the foregoing.

               C. Payment of Accumulated Distributions. Immediately prior to any
redemption of Series A Preferred Units, the Partnership shall pay, in cash, any
accumulated and unpaid distributions on the Series A Preferred Units to be
redeemed through the redemption date. Except as provided above, the Partnership
will make no payment or allowance for unpaid

                                       75

<PAGE>   80
distributions, whether or not in arrears, on Series A Preferred Units for which
a notice of redemption has been given.

               D. Procedures for Redemption. The following provisions set forth
the procedures for Redemption:

                (i)     Notice of redemption will be given by the General
                        Partner to the Partnership concurrently with the notice
                        of the General Partner sent to the holders of its Series
                        A Preferred Shares in connection with such redemption.
                        Such notice shall state: (A) the redemption date; (B)
                        the redemption price; (C) the number of Series A
                        Preferred Units to be redeemed; (D) the place or places
                        where the Series A Preferred Units are to be surrendered
                        for payment of the redemption price; and (E) that
                        distributions on the Series A Preferred Units to be
                        redeemed will cease to accumulate on such redemption
                        date. If less than all of the Series A Preferred Units
                        are to be redeemed, the notice shall also specify the
                        number of Series A Preferred Units to be redeemed.

                (ii)    On or after the redemption date, the General Partner
                        shall present and surrender the certificates, if any,
                        representing the Series A Preferred Units to the
                        Partnership at the place designated in the notice of
                        redemption and thereupon the redemption price of such
                        Units (including all accumulated and unpaid
                        distributions up to the redemption date) shall be paid
                        to the General Partner and each surrendered Unit
                        certificate, if any, shall be canceled. If fewer than
                        all the Units represented by any such certificate
                        representing Series A Preferred Units are to be
                        redeemed, a new certificate shall be issued representing
                        the unredeemed shares.

                (iii)   From and after the redemption date (unless the
                        Partnership defaults in payment of the redemption
                        price), all distributions on the Series A Preferred
                        Units designated for redemption in such notice shall
                        cease to accumulate and all rights of the General
                        Partner, except the right to receive the redemption
                        price thereof (including all accumulated and unpaid
                        distributions up to the redemption date), shall cease
                        and terminate, and such Units shall not be deemed to be
                        outstanding for any purpose whatsoever. At its election,
                        the Partnership, prior to a redemption date, may
                        irrevocably deposit the redemption price (including
                        accumulated and unpaid distributions to the redemption
                        date) of the Series A Preferred Units so called for
                        redemption in trust for the General Partner with a bank
                        or trust company, in which case the redemption notice to
                        General Partner shall (A) state the date of such
                        deposit, (B) specify the office of such bank or trust
                        company as the place of payment of the redemption price
                        and (C) require the General Partner to surrender the
                        certificates, if any, representing such Series A
                        Preferred Units at such place on or about the date fixed
                        in such redemption notice (which may not be later than
                        the redemption date) against payment of the redemption
                        price (including all

                                       76

<PAGE>   81
                        accumulated and unpaid distributions to the redemption
                        date). Any monies so deposited which remain unclaimed by
                        the General Partner at the end of two years after the
                        redemption date shall be returned by such bank or trust
                        company to the Partnership.

               E. No Further Rights. Any Series A Preferred Units that shall at
any time have been redeemed shall, after such redemption, have the status of
authorized but unissued Preferred Units, without designation as to series until
such shares are once more designated as part of a particular series by the
General Partner.

               Section 16.6 Voting Rights

               A. The General Partner shall not have any voting or consent
rights in respect of its partnership interest represented by the Series A
Preferred Units.

               Section 16.7 Transfer Restrictions

               The Series A Preferred Units shall not be transferable.

               Section 16.8 No Conversion Rights

               The Series A Preferred Units shall not be convertible into any
other class or series of interest in the Partnership.

               Section 16.9 No Sinking Fund

               No sinking fund shall be established for the retirement or
redemption of Series A Preferred Units.

                                   ARTICLE 17.
                            SERIES B PREFERRED UNITS

               Section 17.1 Designation and Number

               A series of Partnership Units in the Partnership designated as
the 8N Series B Cumulative Redeemable Preferred Units (the "Series B Preferred
Units") is hereby established. The number of Series B Preferred Units shall be
1,300,000.

               Section 17.2 Ranking

               The Series B Preferred Units shall, with respect to distribution
rights and rights upon voluntary or involuntary liquidation, winding up or
dissolution of the Partnership, rank (i) senior to the Common Units and to all
Partnership Units the terms of which provide that such Partnership Units shall
rank junior to the Series B Preferred Units; (ii) on a parity with the Series A
Preferred Units and all other Parity Preferred Units; and (iii) junior to all
Partnership Units which rank senior to the Series B Preferred Units.

               Section 17.3 Distributions

               A. Payment of Distributions. Subject to the rights of holders of
Parity Preferred Units (including the Series A Preferred Units) as to the
payment of distributions, pursuant to Section 5.1 and Section 16.3.A hereof,
holders of Series B Preferred Units will be entitled to receive, when, as and if
declared by the Partnership acting through the General Partner, out of Available
Cash, cumulative preferential cash distributions in an amount equal to the
Series B Priority Return. Such distributions will be payable (A) quarterly in
arrears, on the 15th day of January, April, July and October of each year and
(B) in the event of (i) an exchange of Series B Preferred Units into Series B
Preferred Shares, or (ii) a redemption of Series B Preferred Units, on the
exchange date or redemption date, as applicable (each a "Series B Preferred Unit
Distribution Payment Date"), commencing on the first of such payment dates to
occur following their original date of issuance. If any date on which
distributions are to be made on the Series B Preferred Units is not a Business
Day, then payment of the distribution to be made on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay) except that, if such Business Day is
in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date. Distributions on the Series B Preferred Units will be
made to the holders of record of the Series B Preferred Units on the relevant
record dates, which will be fifteen (15) days prior to the relevant Preferred
Unit Distribution Payment Date (the "Series B Preferred Unit Partnership Record
Date").

               B. Distributions Cumulative. Notwithstanding the foregoing,
distributions on the Series B Preferred Units will accrue whether or not the
terms and provisions of any agreement of the Partnership at any time prohibit
the current payment of distributions, whether or not the Partnership has
earnings, whether or not there are funds legally available for the payment of
such of such distributions and whether or not such distributions are authorized.
Accrued but unpaid distributions on the Series B Preferred Units will accumulate
as of the Preferred Unit Distribution Payment Date on which they first become
payable.

               C. Priority as to Distributors.

               (i) So long as any Series B Preferred Units are outstanding, no
distribution of cash or other property shall be authorized, declared, paid or
set apart for payment on or with respect to any class or series of Partnership
Interest represented by Junior Units, nor shall any Junior Units or Parity
Preferred Units (including the Series A Preferred Units) be redeemed, purchased
or otherwise acquired for any consideration (or any monies be paid to or made
available for a sinking fund for the redemption of any such Junior Units or
Parity Preferred Units) by the Partnership (except by conversion into or
exchange for other Junior Units or Parity Preferred Units) unless, in each case,
full cumulative distributions have been or contemporaneously are authorized and
paid or authorized and a sum sufficient for the payment thereof set apart for
such payment on the Series B Preferred Units and all classes and series of
outstanding Parity Preferred Units for all distribution periods. The foregoing
sentence will not prohibit (a) distributions payable solely in Junior Units, (b)
the exchange of Junior Units or Parity Preferred Units (including the Series A
Preferred Units) into Partnership Interests of the Partnership ranking junior to
the Series B Preferred Units as to distributions, or (c) the

                                       78

<PAGE>   83
redemption of Partnership Interests corresponding to Series B Preferred Shares,
Parity Preferred Stock (including Series A Preferred Shares) with respect to
distributions or Junior Stock to be purchased by the General Partner pursuant to
the Charter to preserve the General Partner's status as a real estate investment
trust, provided that such redemption shall be upon the same terms as the
corresponding stock purchase pursuant to the Charter.

               (ii) So long as distributions have not been paid in full (or a
sum sufficient for such full payment is not so set apart) upon the Series B
Preferred Units and any other Parity Preferred Units (including the Series A
Preferred Units), all distributions authorized and declared on the Series B
Preferred Units and all classes or series of outstanding Parity Preferred Units
(including the Series A Preferred Units) shall be authorized and declared pro
rata so that the amount of distributions authorized and declared per Series B
Preferred Unit and such other classes or series of Parity Preferred Units shall
in all cases bear to each other the same ratio that accrued distributions per
Series B Preferred Unit and such other classes or series of Parity Preferred
Units (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Units do not have cumulative distribution rights) bear to each other.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distributions or payments on Series B Preferred Units which may be in
arrears.

               (iii) Notwithstanding anything to the contrary set forth herein,
distributions on Partnership Interests held by either (a) the General Partner or
(b) any other holder of Partnership Interest in the Partnership, in each case
ranking junior to or on parity with the Series B Preferred Units may be made,
without preserving the priority of distributions described in Sections 17.3.C(i)
and (ii), but only to the extent such distributions are required to preserve the
real estate investment trust status of the General Partner and in the case of
any holder other than the General Partner only to the extent required by the
Partnership Agreement.

               D. No Further Rights. Holders of Series B Preferred Units shall
not be entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

               Section 17.4 Liquidation Proceeds

               A. Distributions. Upon voluntary or involuntary liquidation,
dissolution or winding-up of the Partnership, distributions on the Series B
Preferred Units shall be made in accordance with Article 13 of this Agreement.

               B. Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by the General Partner
pursuant to Section 13.6 hereof.

               C. No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, Holders of Series B
Preferred Units will have no right or claim to any of the remaining assets of
the Partnership.

                                       79

<PAGE>   84
               D. Consolidation, Merger or Certain Other Transactions. None of a
consolidation or merger of the Partnership with or into another entity, a merger
of another entity with or into the Partnership, or a sale, lease, transfer or
conveyance of all or substantially all of the Partnership's property or business
shall be considered a liquidation, dissolution or winding up of the Partnership.

               Section 17.5 Redemption

               A. Redemption. The Series B Preferred Units may not be redeemed
prior to November 12, 2003. On or after such date, the Partnership shall have
the right to redeem the Series B Preferred Units, in whole or in part, at any
time or from time to time, upon not less than 30 nor more than 60 days' written
notice, at a redemption price, payable in cash, equal to the Capital Account
balance of the holder of Series B Preferred Units (the "Redemption Price");
provided, however, that no redemption pursuant to this Section 17.5 will be
permitted if the Redemption Price does not equal or exceed the original Capital
Contribution of such holder plus the cumulative Priority Return to the
redemption date to the extent not previously distributed. If fewer than all of
the outstanding Series B Preferred Units are to be redeemed, the Series B
Preferred Units to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional units).

               B. Limitation on Redemption. (i) The Redemption Price of the
Series B Preferred Units (other than the portion thereof consisting of
accumulated but unpaid distributions) is payable solely out of the sale proceeds
of capital stock of the General Partner, which will be contributed by the
General Partner to the Partnership as an additional capital contribution, or out
of the sale of limited partner interests in the Partnership and from no other
source. For purposes of the preceding sentence, "capital stock" means any equity
securities (including Common Stock and Preferred Stock (as such terms are
defined in the Charter)), depository shares, interests, participation or other
ownership interests (however designated) and any rights (other than debt
securities convertible into or exchangeable for equity securities) or options to
purchase any of the foregoing.

               (ii) The Partnership may not redeem fewer than all of the
outstanding Series B Preferred Units unless all accumulated and unpaid
distributions have been paid on all Series B Preferred Units for all quarterly
distribution periods terminating on or prior to the date of redemption.

               C. Procedures for Redemption. (i) Notice of redemption will be
(i) faxed, and (ii) mailed by the Partnership, by certified mail, postage
prepaid, not less than 30 nor more than 60 days prior to the redemption date,
addressed to the respective holders of record of the Series B Preferred Units at
their respective addresses as they appear on the records of the Partnership. No
failure to give or defect in such notice shall affect the validity of the
proceedings for the redemption of any Series B Preferred Units except as to the
holder to whom such notice was defective or not given. In addition to any
information required by law, each such notice shall state: (a) the redemption
date, (b) the Redemption Price, (c) the aggregate number of Series B Preferred
Units to be redeemed and if fewer than all of the outstanding Series B Preferred
Units are to be redeemed, the number of Series B Preferred Units to be redeemed
held by such

                                       80

<PAGE>   85
holder, which number shall equal such holder's pro rata share (based on the
percentage of the aggregate number of outstanding Series B Preferred Units that
the total number of Series B Preferred Units held by such holder represents) of
the aggregate number of Series B Preferred Units to be redeemed, (d) the place
or places where such Series B Preferred Units are to be surrendered for payment
of the Redemption Price, (e) that distributions on the Series B Preferred Units
to be redeemed will cease to accumulate on such redemption date and (f) that
payment of the Redemption Price will be made upon presentation and surrender of
such Series B Preferred Units.

               (ii) If the Partnership gives a notice of redemption in respect
of Series B Preferred Units (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Partnership will deposit
irrevocably in trust for the benefit of the Series B Preferred Units being
redeemed funds sufficient to pay the applicable Redemption Price and will give
irrevocable instructions and authority to pay such Redemption Price to the
holders of the Series B Preferred Units upon surrender of the Series B Preferred
Units by such holders at the place designated in the notice of redemption. On
and after the date of redemption, distributions will cease to accumulate on the
Series B Preferred Units or portions thereof called for redemption, unless the
Partnership defaults in the payment thereof. If any date fixed for redemption of
Series B Preferred Units is not a Business Day, then payment of the Redemption
Price payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day falls in the next calendar year, such
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date fixed for redemption. If
payment of the Redemption Price is improperly withheld or refused and not paid
by the Partnership, distributions on such Series B Preferred Units will continue
to accumulate from the original redemption date to the date of payment, in which
case the actual payment date will be considered the date fixed for redemption
for purposes of calculating the applicable Redemption Price.

               Section 17.6 Voting Rights

               A. General. Holders of the Series B Preferred Units will not have
any voting rights or right to consent to any matter requiring the consent or
approval of the Limited Partners, except as set forth below and in Section
7.3.E.

               B. Certain Voting Rights. So long as any Series B Preferred Units
remains outstanding, the Partnership shall not, without the affirmative vote of
the holders of at least two-thirds of the Series B Preferred Units outstanding
at the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests ranking prior to the Series B
Preferred Units with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up or reclassify any Partnership Interests
of the Partnership into any such Partnership Interest, or create, authorize or
issue any obligations or security convertible into or evidencing the right to
purchase any such Partnership Interests, (ii) authorize or create, or increase
the authorized or issued amount of any Parity Preferred Units or reclassify any
Partnership Interest of the Partnership into any such Partnership Interest or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such

                                       81

<PAGE>   86
Partnership Interests but only to the extent such Parity Preferred Units are
issued to an affiliate of the Partnership, other than the General Partner to the
extent the issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not affiliates of the
Partnership or (iii) either consolidate, merge into or with, or convey, transfer
or lease its assets substantially as an entirety to, any corporation or other
entity or amend, alter or repeal the provisions of the Partnership Agreement
(including, without limitation, this Article 17), whether by merger,
consolidation or otherwise, in each case in a manner that would materially and
adversely affect the powers, special rights, preferences, privileges or voting
power of the Series B Preferred Units or the holders thereof; provided, however,
that with respect to the occurrence of any event set forth in (iii) above, so
long as (a) the Partnership is the surviving entity and the Series B Preferred
Units remain outstanding with the terms thereof unchanged, or (b) the resulting,
surviving or transferee entity is a partnership, limited liability company or
other pass-through entity organized under the laws of any state and substitutes
the Series B Preferred Units for other interests in such entity having
substantially the same terms and rights as the Series B Preferred Units,
including with respect to distributions, voting rights and rights upon
liquidation, dissolution or winding-up, then the occurrence of any such event
shall not be deemed to materially and adversely affect such rights, privileges
or voting powers of the holders of the Series B Preferred Units; and provided
further, that any increase in the amount of Partnership Interests or the
creation or issuance of any other class or series of Partnership Interests
represented by Junior Units or Parity Preferred Units are not issued to an
affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not affiliates of the
Partnership, shall not be deemed to materially and adversely affect such rights,
preferences, privileges or voting powers.

               Section 17.7 Transfer Restrictions

               The Series B Preferred Units shall be subject to the provisions
of Article 11 hereof; provided, however, that the Series B Preferred Units shall
not be subject to the right of first refusal of the General Partner as described
in Section 11.3 hereof. No transfer of Series B Preferred Units, or other action
by the holder or holders of such Units, is permitted, without the consent of the
General Partner which consent may be given or withheld in its sole and absolute
discretion, if such transfer or other action would result in more than four
partners holding all outstanding Series B Preferred Units within the meaning of
Treasury Regulation Section 1.7704-1(h)(3)(i); provided, however, that the
General Partner's consent may not be unreasonably withheld if (a) such transfer
or other action would not result in more than ten partners holding all
outstanding Series B Preferred Units within the meaning of Treasury Regulation
Section 1.7704-1(h)(3)(i) and (b) the General Partner is relying on a provision
other than Treasury Regulation Section 1.7704-1(h) to avoid classification of
Operating Partnership as a "publicly traded partnership" within the meaning of
Code Section 7704 (a "PTP"). In addition, no transfer may be made to any person
if such transfer would cause the exchange of the Series B Preferred Units for
Series B Preferred Shares, as provided herein, to be required to be registered
under the Securities Act of 1933, as amended, or any state securities laws. If
(i) Contributor concludes based on results or projected results that there
exists (in the reasonable judgment of Contributor) an imminent and substantial
risk that the Contributor's interest in the Partnership represents or will
represent more than 19.5% of the total profits or capital interests in the
Partnership for a

                                       82

<PAGE>   87
taxable year, (ii) Contributor delivers to the General Partner an opinion of
independent counsel to the effect that there is a substantial risk that
Contributor's interest in the Partnership represents or will represent more than
19.5% (the "19.5% Limit") of the total profits or capital interests in the
Partnership (determined in accordance with Regulations Section 1.731-2(e)(4)),
and (iii) the General Partner agrees with the conclusions referred to in clauses
(i) and (ii) of this sentence, such agreement not to be unreasonably withheld,
then Contributor shall, subject to the above limitations, be permitted to
transfer so much of its Series B Preferred Units as may be appropriate to
alleviate the risk of not satisfying the 19.5% Limit to the trust described in
Exhibit J, with the Contributor having the rights set forth in such Exhibit.

               Section 17.8 Exchange Rights

               A. Right to Exchange. (i) Series B Preferred Units will be
exchangeable in whole but not in part unless expressly otherwise provided herein
at anytime on or after November 12, 2008, at the option of 51% of the holders of
all outstanding Series B Preferred Units, for authorized but previously unissued
Series B Preferred Shares at an exchange rate of one REIT Series B Preferred
Share from the General Partner for one Series B Preferred Unit, subject to
adjustment as described below (the "Exchange Price"), provided that the Series B
Preferred Units will become exchangeable at any time, in whole but not in part
unless expressly otherwise provided herein, at the option of 51% of the holders
of all outstanding Series B Preferred Units for Series B Preferred Shares if (y)
at any time full distributions shall not have been timely made on any Series B
Preferred Unit with respect to six (6) prior quarterly distribution periods,
whether or not consecutive, provided, however, that a distribution in respect of
Series B Preferred Units shall be considered timely made if made within two (2)
Business Days after the applicable Preferred Unit Distribution Payment Date if
at the time of such late payment there shall not be any prior quarterly
distribution periods in respect of which full distributions were not timely made
or (z) upon receipt by a holder or holders of Series B Preferred Units of (A)
notice from the General Partner that the General Partner or a Subsidiary of the
General Partner has taken the position that the Partnership is, or upon the
consummation of an identified event in the immediate future will be, a PTP and
(B) an opinion rendered by independent counsel familiar with such matters
addressed to a holder or holders of Series B Preferred Units, that the
Partnership is or likely is, or upon the occurrence of a defined event in the
immediate future will be or likely will be, a PTP. In addition, the Series B
Preferred Units may be exchanged for Series B Preferred Shares, in whole but not
in part unless expressly otherwise provided herein, at the option of 51% of the
holders of all outstanding Series B Preferred Units after November 12, 2001 and
prior to November 12, 2008 if such holders of a Series B Preferred Units shall
deliver to the General Partner either (i) a private ruling letter addressed to
such holder of Series B Preferred Units or (ii) an opinion of independent
counsel reasonably acceptable to the General Partner based on the enactment of
temporary or final Treasury Regulations or the publication of a Revenue Ruling,
in either case to the effect that an exchange of the Series B Preferred Units at
such earlier time would not cause the Series B Preferred Units to be considered
"stock and securities" within the meaning of section 351(e) of the Code for
purposes of determining whether the holder of such Series B Preferred Units is
an "investment company" under section 721(b) of the Code if an exchange is
permitted at such earlier date. Furthermore, the Series B Preferred Units, if
Contributor so determines, may be exchanged in whole but not in part (regardless
of whether held by Contributor) for Series B

                                       83

<PAGE>   88
Preferred Shares (but only if the exchange in whole may be accomplished
consistently with the ownership limitations set forth under the Series B
Articles Supplementary (as defined herein), taking into account exceptions
thereto) if (1) Contributor concludes based on results or projected results that
there exists (in the reasonable judgment of Contributor) an imminent and
substantial risk that the Contributor's interest in the Partnership represents
or will represent more than 19.5% of the total profits or capital interests in
the Partnership for a taxable year, (2) Contributor delivers to the General
Partner an opinion of independent counsel to the effect that there is a
substantial risk that its interest in the Partnership does not or will not
satisfy the 19.5% Limit and (3) the General Partner agrees with the conclusions
referred to in clauses (1) and (2) of this sentence, such agreement not to be
unreasonably withheld; provided, however, that if, as a result of such
conclusion, Contributor's interest in the Partnership is reduced pursuant to the
last sentence of Section 17.7 hereof (which procedure shall be available to
Contributor to the exclusion of the procedure under this sentence for so long
as, on a cumulative basis, sales of 10% or fewer of the Series B Preferred Units
originally acquired by Contributor would in the opinion of the above-referenced
counsel reduce the risk that Contributor's interest in the Partnership would not
satisfy the 19.5% Limit to less than a substantial risk, and thereafter shall be
a permitted alternative to the procedure pursuant to this sentence) or the risk
of Contributor not satisfying the 19.5% Limit otherwise is reduced below a
substantial risk, then an exchange in whole under this sentence shall not be
permitted unless and until a change in facts occurs and a further determination
by Contributor is made under this sentence.

               (ii) Notwithstanding anything to the contrary set forth in
Section 17.8.A(i), if an Exchange Notice (as defined herein) has been delivered
to the General Partner, then the General Partner may, at its option, within ten
(10) Business Days after receipt of the Exchange Notice, elect to cause the
Partnership to redeem all or a portion of the outstanding Series B Preferred
Units for cash in an amount equal to the original Capital Contribution per
Series B Preferred Unit and all accrued and unpaid distributions thereon to the
date of redemption. If the General Partner elects to redeem fewer than all of
the outstanding Series B Preferred Units, the number of Series B Preferred Units
held by each holder to be redeemed shall equal such holder's pro rata share
(based on the percentage of the aggregate number of outstanding Series B
Preferred Units that the total number of Series B Preferred Units held by such
holder represents) of the aggregate number of Series B Preferred Units being
redeemed.

               (iii) In the event an exchange of all Series B Preferred Units
pursuant to Section 17.8.A would violate the provisions on ownership limitation
of the General Partner set forth in Section 7 of the Articles Supplementary to
the Charter with respect to Series B Preferred Shares (the "Series B Articles
Supplementary"), each holder of Series B Preferred Units shall be entitled to
exchange, pursuant to the provisions of Section 17.8.B, a number of Series B
Preferred Units which would comply with the provisions on the ownership
limitation of the General Partner set forth in such Section 7 of the Series B
Articles Supplementary, with respect to such holder, and any Series B Preferred
Units not so exchanged (the "Excess Units") shall be redeemed by the Partnership
for cash in an amount equal to the original Capital Contribution per Excess
Unit, plus any accrued and unpaid distributions thereon to the date of
redemption subject to any restriction thereon contained in any debt instrument
or agreement of the Partnership. In the event an exchange would result in Excess
Units, as a condition to such exchange, each holder of such units agrees to
provide representations and covenants reasonably requested by the

                                       84

<PAGE>   89
General Partner relating to (i) the widely held nature of the interests in such
holder, sufficient to assure the General Partner that the holder's ownership of
stock of the General Partner (without regard to the limits described above) will
not cause any individual to own in excess of 9.0% of the stock of the General
Partner; and (ii) to the extent such holder can so represent and covenant
without obtaining information from its owners, the holder's ownership of tenants
of the Partnership and its affiliates. For purposes of determining the number of
Excess Units under this Section 17.8.A(iii), the "Beneficial Ownership Limit"
and "Constructive Ownership Limit" set forth in the Series B Articles
Supplementary shall be deemed to be 9.0%. To the extent the General Partner
would not be able to pay the cash set forth above in exchange for the Excess
Units, and to the extent consistent with the Charter, the General Partner agrees
that it will grant to the holders of the Series B Preferred Units exceptions to
the Beneficial Ownership Limit and Constructive Ownership Limit set forth in the
Series B Articles Supplementary sufficient to allow such holders to exchange all
of their Series B Preferred Units for REIT Series B Preferred Stock, provided
such holders furnish to the General Partner representations acceptable to the
General Partner in its sole and absolute discretion which assure the General
Partner that such exceptions will not jeopardize the General Partner's tax
status as a REIT for purposes of federal and applicable state law.
Notwithstanding any provision of this Agreement to the contrary, no Series B
Limited Partner shall be entitled to effect an exchange of Series B Preferred
Units for Series B Preferred Shares to the extent that ownership or right to
acquire such shares would cause the Partner or any other Person or, in the
opinion of counsel selected by the General Partner, may cause the Partner or any
other Person, to violate the restrictions on ownership and transfer of Series B
Preferred Shares set forth in the Charter. To the extent any such attempted
exchange for Series B Preferred Shares would be in violation of the previous
sentence, it shall be void ab initio and such Series B Limited Partner shall not
acquire any rights or economic interest in the Series B Preferred Shares
otherwise issuable upon such exchange.

               (iv) The redemption of Series B Preferred Units described in
Section 17.8.A(ii) and (iii) shall be subject to the provisions of Section
17.5.B(i) and Section 17.5.C(ii); provided, however, that the term "Redemption
Price" in such Sections 17.5.B(i) and 17.5.C(ii) shall be read to mean the
original Capital Contribution per Series B Preferred Unit being redeemed as set
forth on Exhibit A plus all accrued and unpaid distributions to the redemption
date.

               B. Procedure for Exchange and/or Redemption of Series B Preferred
Units.

               (i) Any exchange shall be exercised pursuant to a notice of
exchange (the "Exchange Notice") delivered to the General Partner by the
Partners representing at least 51% of the outstanding Series B Preferred Units
(or by Contributor in the case of an exchange pursuant to the last sentence of
Section 17.8.A.(i) hereof) by (a) fax and (b) by certified mail postage prepaid.
The General Partner may effect any exchange of Series B Preferred Units, or
exercise its option to cause the Partnership to redeem any portion of the Series
B Preferred Units for cash pursuant to Section 17.8.A(ii) or redeem Excess Units
pursuant to Section 17.8.A(iii), by delivering to each holder of record of
Series B Preferred Units, within ten (10) Business Days following receipt of the
Exchange Notice, (a) if the General Partner elects to cause the Partnership to
acquire any of the Series B Preferred Units then outstanding, (1) certificates
representing the Series B Preferred Shares being issued in exchange for the
Series B Preferred Units of such holder being exchanged and (2) a written notice
(a "Redemption Notice") stating

                                       85

<PAGE>   90
(A) the redemption date, which may be the date of such Redemption Notice or any
other date which is not later than sixty (60) days following the receipt of the
Exchange Notice, (B) the redemption price, (C) the place or places where the
Series B Preferred Units are to be surrendered and (D) that distributions on the
Series B Preferred Units will cease to accrue on such redemption date, or (b) if
the General Partner elects to cause the Partnership to redeem all of the Series
B Preferred Units then outstanding in exchange for cash, a Redemption Notice.
Series B Preferred Units shall be deemed canceled (and any corresponding
Partnership Interest represented thereby deemed terminated) simultaneously with
the delivery of shares of Series B Preferred Shares (with respect to Series B
Preferred Units exchanged) or simultaneously with the redemption date (with
respect to Series B Preferred Units redeemed). Holders of Series B Preferred
Units shall deliver any canceled certificates representing Series B Preferred
Units which have been exchanged or redeemed to the office of General Partner
(which currently is located at 505 Montgomery Street, San Francisco, California
94111) within ten (10) Business Days of the exchange or redemption with respect
thereto. Notwithstanding anything to the contrary contained herein, any and all
Series B Preferred Units to be exchanged for REIT Series B Preferred Stock
pursuant to this Section 17.8 shall be so exchanged in a single transaction at
one time. As a condition to exchange, the General Partner may require the
holders of Series B Preferred Units to make such representations as may be
reasonably necessary for the General Partner to establish that the issuance of
Series B Preferred Shares pursuant to the exchange shall not be required to be
registered under the Securities Act or any state securities laws. Any Series B
Preferred Shares issued pursuant to this Section 17.8 shall be delivered as
shares which are duly authorized, validly issued, fully paid and nonassessable,
free of any pledge, lien, encumbrance or restriction other than those provided
in the Charter, the Bylaws of the General Partner, the Securities Act and
relevant state securities or blue sky laws.

               The certificates representing the Series B Preferred Shares
issued upon exchange of the Series B Preferred Units shall contain the following
legend:

               THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
               TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE
               DISPOSED OF EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION
               STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "ACT"), AND STATE SECURITIES LAWS OR (B) IF THE CORPORATION HAS
               BEEN FURNISHED WITH A SATISFACTORY OPINION OF COUNSEL FOR THE
               HOLDER OF THE SHARES REPRESENTED HEREBY, OR OTHER EVIDENCE
               SATISFACTORY TO THE CORPORATION, THAT SUCH TRANSFER, SALE,
               ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT
               FROM THE PROVISIONS OF SECTION 5 OF THE ACT AND STATE SECURITIES
               LAWS AND THE RULES AND REGULATIONS THEREUNDER.

               (ii) In the event of an exchange of Series B Preferred Units for
Series B Preferred Shares, an amount equal to the accrued and unpaid
distributions to the date of exchange

                                       86

<PAGE>   91
on any Series B Preferred Units tendered for exchange shall (i) accrue on the
Series B Preferred Shares into which such Series B Preferred Units are
exchanged, and (ii) continue to accrue on such Series B Preferred Units, which
shall remain outstanding following such exchange, with the General Partner as
the holder of such REIT Series B Preferred Units. Notwithstanding anything to
the contrary set forth herein, in no event shall a holder of a Series B
Preferred Unit that was validly exchanged for Series B Preferred Shares pursuant
to this Section (other than the General Partner holding such Series B Preferred
Unit following any such exchange), receive a distribution out of Available Cash
of the Partnership, if such holder, after exchange, is entitled to receive a
distribution out of Available Cash with respect to the Series B Preferred Shares
for which such Series B Preferred Unit was exchanged or redeemed. Further for
purposes of the foregoing, in the event of an exchange of Series B Preferred
Units for Series B Preferred Shares, if the accrued and unpaid distributions per
Series B Preferred Unit is not the same for each Series B Preferred Unit, the
accrued and unpaid distributions per Series B Preferred Unit for each such
Series B Preferred Unit shall be equal to the greatest amount of such accrued
and unpaid distributions per Series B Preferred Unit on any such unit.

               (iii) Fractional Series B Preferred Shares are not to be issued
upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series B Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Directors of the General Partner.

               C. Adjustment of Exchange Price. In case the General Partner
shall be a party to any transaction (including, without limitation, a merger,
consolidation, statutory share exchange, tender offer for all or substantially
all of the General Partner's capital stock or sale of all or substantially all
of the General Partner's assets), in each case as a result of which the Series B
Preferred Shares will be converted into the right to receive shares of capital
stock, other securities or other property (including cash or any combination
thereof), each Series B Preferred Unit will thereafter be exchangeable into the
kind and amount of shares of capital stock and other securities and property
receivable (including cash or any combination thereof) upon the consummation of
such transaction by a holder of that number of Series B Preferred Shares or
fraction thereof into which one Series B Preferred Unit was exchangeable
immediately prior to such transaction. The General Partner may not become a
party to any such transaction unless the terms thereof are consistent with the
foregoing.

               Section 17.9 No Conversion Rights

               The Series B Preferred Units shall not be convertible into any
other class or series of interest in the Partnership.

               Section 17.10 No Sinking Fund

               No sinking fund shall be established for the retirement or
redemption of Series B Preferred Units.

                        CONSTRUCTIVE OWNERSHIP DEFINITION

               The term "Constructively Owns" means ownership determined through
the application of the constructive ownership rules of Section 318 of the Code,
as modified by Section 856(d)(5) of the Code. Generally, these rules provide the
following:

        a. an individual is considered as owning the Ownership Interest that is
owned, actually or constructively, by or for his spouse, his children, his
grandchildren, and his parents;

        b. an Ownership Interest that is owned, actually or constructively, by
or for a partnership, limited liability company or estate is considered as owned
proportionately by its partners, members or beneficiaries;

        c. an Ownership Interest that is owned, actually or constructively, by
or for a trust is considered as owned by its beneficiaries in proportion to the
actuarial interest of such beneficiaries (provided, however, that in the case of
a "grantor trust" the Ownership Interest will be considered as owned by the
grantors);

        d. if ten percent (10%) or more in value of the stock in a corporation
is owned, actually or constructively, by or for any person, such person shall be
considered as owning the Ownership Interest that is owned, actually or
constructively, by or for such corporation in that proportion which the value of
the stock which such person so owns bears to the value of all the stock in such
corporation;

        e. an Ownership Interest that is owned, actually or constructively, by
or for a partner or member which actually or constructively owns a 25% or
greater capital interest or profits interest in a partnership or limited
liability company, or by or for a beneficiary of an estate or trust, shall be
considered as owned by the partnership, limited liability company, estate, or
trust (or, in the case of a grantor trust, the grantors);

        f. if ten percent (10%) or more in value of the stock in a corporation
is owned, actually or constructively, by or for any person, such corporation
shall be considered as owning the Ownership Interest that is owned, actually or
constructively, by or for such person;

        g. if any person has an option to acquire an Ownership Interest
(including an option to acquire an option or any one of a series of such
options), such Ownership Interest shall be considered as owned by such person;

        h. an Ownership Interest that is constructively owned by a person by
reason of the application of the rules described in paragraphs (a) through (g)
above shall, for purposes of applying paragraphs (a) through (g), be considered
as actually owned by such person provided, however, that (i) an Ownership
Interest constructively owned by an individual by reason of paragraph (a) shall
not be considered as owned by him for purposes of again applying paragraph (a)
in order to make another the constructive owner of such Ownership Interest, (ii)
an Ownership Interest constructively owned by a partnership, estate, trust, or
corporation by reason of the application of paragraphs (e) or (f) shall not be
considered as owned by it for purposes of applying paragraphs (b), (c), or (d)
in order to make another the constructive owner of such Ownership Interest,
(iii) if an Ownership Interest may be considered as owned by an individual under
paragraphs (a) or (g), it shall be considered as owned by him under paragraph
(g) and (iv) for purposes of the above described rules, an S corporation shall
be treated as a partnership and any stockholder of the S corporation shall be
treated as a partner of such partnership except that this rule shall not apply
for purposes of determining whether stock in the S corporation is constructively
owned by any person.

        i. For purposes of the above summary of the constructive ownership
rules, the term "Ownership Interest" means the ownership of stock with respect
to a corporation and, with respect to any other type of entity, the ownership of
an interest in either its assets or net profits.

                    "Trust" shall mean each of the trusts provided for in

                    "Trustee" shall mean any Person unaffiliated with the

Capitalized terms used and not defined herein shall have the meanings ascribed

in excess of the Ownership Limit if the representations contained in Section
3.4.D are not at such time true and correct.

               (ii) If, prior to the Restriction Termination Date, any Transfer
or other event occurs that, if effective, would result in any Person
Constructively Owning Partnership Units in violation of subsection (b)(i), (1)
then that number of Partnership Units that otherwise would cause such Person to
violate subsection (b)(i) (rounded up to the nearest whole Partnership Unit)
shall be automatically transferred (provided such Transfer is not in violation
of the restrictions on transfer set forth in the Partnership Agreement, except
to the extent the General Partner waives such restrictions) to a Trust for the
benefit of a Charitable Beneficiary, as described in subsection (c),

                                      J-2

<PAGE>   112
effective as of the close of business on the business day prior to the date of
such Transfer or other event, and such Purported Beneficial Transferee shall
thereafter have no rights in such Partnership Units or (2) if, for any reason,
the transfer to the Trust described in clause (1) of this sentence is not
automatically effective as provided therein to prevent any Person from
Constructively Owning Partnership Units in violation of subsection (b)(i), then
the Transfer of that number of Partnership Units that otherwise would cause any
Person to violate subsection (b)(i) shall be void ab initio, and the Purported
Beneficial Transferee shall have no rights in such Partnership Units.

        (c) Transfers of Partnership Units in Trust.

               (i) Upon any purported Transfer or other event described in
subsection (b)(ii), such Partnership Units shall be deemed to have been
transferred to the Trustee in his capacity as trustee of a Trust for the
exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the
Trustee shall be deemed to be effective as of the close of business on the
business day prior to the purported Transfer or other event that results in a
transfer to the Trust pursuant to subsection (b)(ii). The Trustee shall be
appointed by the Partnership and shall be a Person unaffiliated with the
Partnership, any Purported Beneficial Transferee, or any Purported Record
Transferee. Each Charitable Beneficiary shall be designated by the Partnership
as provided in subsection (c)(vi).

               (ii) Partnership Units held by the Trustee shall be issued and
outstanding Partnership Units of the Partnership. The Purported Beneficial
Transferee or Purported Record Transferee shall have no rights in the
Partnership Units held by the Trustee. The Purported Beneficial Transferee or
Purported Record Transferee shall not benefit economically from ownership of any
Partnership Units held in trust by the Trustee, shall have no rights to
distributions or allocations with respect to Partnership Units held in the Trust
and shall not possess any rights to vote or other rights attributable to the
Partnership Units held in the Trust.

               (iii) The Trustee shall have all voting rights and rights to
distributions and allocations with respect to Partnership Units held in the
Trust, which rights shall be exercised for the exclusive benefit of the
Charitable Beneficiary. Any distribution paid prior to the discovery by the
Partnership that Partnership Units have been transferred to the Trustee shall be
paid to the Trustee upon demand, and any distribution with respect to such
Partnership Units shall be paid when due to the Trustee. Any distributions so
paid over to the Trustee shall be held in trust for the Charitable Beneficiary.

               The Purported Record Transferee and Purported Beneficial
Transferee shall have no voting rights with respect to the Partnership Units
held in the Trust and, subject to Delaware law, effective as of the date the
Partnership Units has been transferred to the Trustee, the Trustee shall have
the authority (at the Trustee's sole discretion) (i) to rescind as void any vote
cast by a Purported Record Transferee with respect to such Partnership Units
prior to the discovery by the Partnership that the Partnership Units has been
transferred to the Trustee and (ii) to recast such vote in accordance with the
desires of the Trustee acting for the benefit of the Charitable Beneficiary;
provided, however, that if the Partnership has already taken irreversible
action, then the Trustee shall not have the authority to rescind and recast such
vote. Notwithstanding any other provision of this Exhibit J to the contrary,
until the Partnership has received notification that the Partnership Units have
been transferred into a Trust, the Partnership shall be entitled to rely on its
Partnership

                                      J-3

<PAGE>   113
Unit transfer and other unitholder records for purposes of preparing Exhibit A
to the Partnership Agreement, lists of unitholders entitled to vote at meetings,
and otherwise conducting votes of Partners.

               (iv) Within 20 days of receiving notice from the Partnership that
Partnership Units have been transferred to the Trust, the Trustee of the Trust
shall, in accordance with the terms of (and subject to the limitations contained
in) the Partnership Agreement, sell the Partnership Units held in the Trust to a
Person, designated by the Trustee, whose ownership of the Partnership Units will
not violate the ownership limitations set forth in subsection (b)(i). Upon such
sale, the interest of the Charitable Beneficiary in the Partnership Units sold
shall terminate and the Trustee shall distribute the net proceeds of the sale to
the Purported Record Transferee and to the Charitable Beneficiary as provided in
this subsection (c)(iv). The Purported Record Transferee shall receive the
lesser of (1) the price paid by the Purported Record Transferee for the
Partnership Units in the transaction that resulted in such transfer to the Trust
(or, if the event which resulted in the transfer to the Trust did not involve a
purchase of such Partnership Units at Market Price, the Market Price of such
Partnership Units on the day of the event which resulted in the transfer of such
Partnership Units to the Trust) and (2) the price per Partnership Unit received
by the Trustee (net of any commissions and other expenses of sale) from the sale
or other disposition of the Partnership Units held in the Trust. Any net sales
proceeds in excess of the amount payable to the Purported Record Transferee
shall be immediately paid to the Charitable Beneficiary together with any
distributions thereon. If, prior to the discovery by the Partnership that
Partnership Units have been transferred to the Trustee, such Partnership Units
are sold by a Purported Record Transferee then (i) such Partnership Units shall
be deemed to have been sold on behalf of the Trust and (ii) to the extent that
the Purported Record Transferee received an amount for such Partnership Units
that exceeds the amount that such Purported Record Transferee was entitled to
receive pursuant to this subsection (c)(iv), such excess shall be paid to the
Trustee upon demand. The expenses described in item (2) above shall include any
expenses of administering the Trust, any transfer of Partnership Units thereto
or disposition of Partnership Units thereby, which shall be allocated equitably
among the Partnership Units which are transferred to the Trust.

               (v) Partnership Units transferred to the Trustee shall be deemed
to have been offered for sale to the Partnership, or its designee, at a price
per Partnership Unit equal to the lesser of (i) the price paid by the Purported
Record Transferee for the Partnership Units in the transaction that resulted in
such transfer to the Trust (or, if the event which resulted in the transfer to
the Trust did not involve a purchase of such Partnership Units at Market Price,
the Market Price of such Partnership Units on the day of the event which
resulted in the transfer of such Partnership Units to the Trust) and (ii) the
Market Price on the date the Partnership, or its designee, accepts such offer.
The Partnership shall have the right to accept such offer until the Trustee has
sold the Partnership Units held in the Trust pursuant to subsection (c)(iv).
Upon such a sale to the Partnership, the interest of the Charitable Beneficiary
in the Partnership Units sold shall terminate and the Trustee shall distribute
the net proceeds of the sale to the Purported Record Transferee and any
distributions held by the Trustee with respect to such Partnership Units shall
thereupon be paid to the Charitable Beneficiary.

               (vi) By written notice to the Trustee, the Partnership shall
designate one or more nonprofit organizations to be the Charitable Beneficiary
of the interest in the Trust such that the

                                      J-4

<PAGE>   114
Partnership Units held in the Trust would not violate the restrictions set forth
in subsection (b)(i) in the hands of such Charitable Beneficiary.

        (d) Remedies For Breach. If the General Partner shall at any time
determine in good faith that a Transfer or other event has taken place in
violation of subsection (b) or that a Person intends to acquire, has attempted
to acquire or may acquire beneficial ownership (determined without reference to
any rules of attribution) or Constructive Ownership of any Partnership Units of
the Partnership in violation of subsection (b), the General Partner shall take
such action as it deems advisable to refuse to give effect or to prevent such
Transfer, including, but not limited to, causing the Partnership to redeem
Partnership Units, refusing to give effect to such Transfer on the books of the
Partnership or instituting proceedings to enjoin such Transfer; provided,
however, that any Transfers (or, in the case of events other than a Transfer,
ownership or Constructive Ownership) in violation of subsection (b)(i), shall
automatically result in the transfer to a Trust as described in subsection
(b)(ii).

        (e) Notice of Restricted Transfer. Any Person who acquires or attempts
to acquire or own Partnership Units in violation of subsection (b), or any
Person who is a Purported Beneficial Transferee such that an automatic transfer
to a Trust results under subsection (b)(ii), shall immediately give written
notice to the Partnership of such event and shall provide to the Partnership
such other information as the Partnership may request in order to determine the
effect, if any, of such Transfer or attempted Transfer on such Person's
compliance with subsection (b)(i).

        (f) Owners Required To Provide Information. Prior to the Restriction
Termination Date each Person who is a beneficial owner or Constructive Owner of
Partnership Units and each Person who is holding Partnership Units for a
beneficial owner or Constructive Owner shall provide to the Partnership such
information that the Partnership may request, in good faith, in order to
determine the Partnership's status as a partnership (as opposed to a
corporation) or the General Partner's status as a REIT for federal income tax
purposes.

        (g) Remedies Not Limited. Nothing contained in this Exhibit J shall
limit the authority of the General Partner to take such other action as it deems
necessary or advisable to protect the Partnership and the interests of its
Partners by preservation of the Partnership's status as a partnership (as
opposed to a corporation) or the General Partner's status as a REIT for federal
income tax purposes.

        (h) Ambiguity. In the case of an ambiguity in the application of any of
the provisions of this Exhibit J, including any definition contained in
subsection (a), the General Partner shall have the power to determine the
application of the provisions of this Exhibit J with respect to any situation
based on the facts known to it. In the event that a provision of this Exhibit J
requires an action by the General Partner and Exhibit J fails to provide
specific guidance with respect to such action, the General Partner shall have
the power to determine the action to be taken so long as such action is not
contrary to the provisions of Exhibit J. Absent a decision to the contrary by
the General Partner (which the General Partner may make in its sole and absolute
discretion), if a Person would have (but for the remedies set forth in
subsection (b)) acquired Constructive Ownership of Partnership Units in
violation of subsection (b)(i), such remedies (as applicable) shall apply first
to the Partnership Units which, but for such remedies, would have been actually
owned

                                       J-5

<PAGE>   115
by such Person, and second to Partnership Units which, but for such remedies,
would have been Constructively Owned (but not actually owned) by such Person,
pro rata among the Persons who actually own such Partnership Units based upon
the relative number of the Partnership Units held by each such Person.

                                 ---------------

                                    RECITALS
                                    --------

         I. Capitalized terms used herein and not defined herein shall have the
meanings assigned to such terms in the Credit Agreement.

         II. The Borrower has requested that the Administrative Agent agree to

                  of Article 8(h) and 8(i) of the Credit Agreement, provided,

         times: (i) terminate the Revolving Commitments, and thereupon the
         Revolving Commitments shall terminate immediately and (ii) declare the
         Loans then outstanding to be due and payable in whole (or in part, in
         which case any principal not so declared to be due and payable may
         thereafter be declared to be due and payable), and thereupon the
         principal of the Loans so declared to be due and payable, together with
         accrued interest thereon and all fees and other obligations of each
         Loan Party accrued under the Loan Documents, shall become due and
         payable immediately, without presentment, demand, protest or other

                                       2
<PAGE>   3

         notice of any kind, all of which are hereby waived by the Borrower; and
         (B) in case of any event described in clause (h) or (i) of this

offsets against any such obligation, (c) represents and warrants that no Event

date, and (d) agrees to pay the reasonable fees and disbursements of Bryan Cave
LLP, special counsel to the Administrative Agent, in connection with this
Amendment.

         9. In all other respects (a) the Loan Documents shall remain in full
