                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                               BIOMED REALTY, L.P.

                  THIS SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED
PARTNERSHIP, dated as of August 13, 2004, is entered into by and among BioMed
Realty Trust, Inc., a Maryland corporation (the "Company"), as the General
Partner, and the Persons whose names are set forth on Exhibit A attached hereto,
as the Limited Partners, together with any other Persons who become Partners in
the Partnership as provided herein.

                  WHEREAS, the limited partnership was formed on April 30, 2004
and an original agreement of limited partnership was entered into between the
Company, as general partner, and Alan D. Gold, as limited partner (the "Original
Partnership Agreement");

                  WHEREAS, the Original Partnership Agreement was amended and
restated by that certain Amended and Restated Agreement of Limited Partnership
of BioMed Realty, L.P., dated as of August 11, 2004 (the "First Amended and
Restated Partnership Agreement"), by and between the Company, as general partner
and limited partner, and Alan D. Gold, as limited partner (together, the
"Current Partners"), in connection with the initial public offering of the
Company's common stock; and

                  WHEREAS, the Current Partners and the Partnership believe it
is desirable and in the best interest of the Partnership to amend and restate
the First Amended and Restated Partnership Agreement as set forth herein.

                  NOW, THEREFORE, BE IT RESOLVED, that the Current Partners and
the Partnership hereby amend and restate the First Amended and Restated
Partnership Agreement as follows:

                                   ARTICLE 1.
                                  DEFINED TERMS

Section 1.1       Definitions.

                  The following definitions shall be for all purposes, unless
otherwise clearly indicated to the contrary, applied to the terms used in this
Agreement.

                  "Act" means the Maryland Revised Uniform Limited Partnership
Act, as it may be amended from time to time, and any successor to such statute.

                  "Additional Funds" shall have the meaning set forth in Section
4.3.A.

                  "Additional Limited Partner" means a Person admitted to the
Partnership as a Limited Partner pursuant to Section 12.2 and who is shown as
such on the books and records of the Partnership.

<PAGE>

                  "Adjusted Capital Account Deficit" means, with respect to any
Partner, the deficit balance, if any, in such Partner's Capital Account as of
the end of the relevant fiscal year, after giving effect to the following
adjustments:

                  (i)      such deficit shall be decreased by any amounts which
                           such Partner is obligated to restore pursuant to this
                           Agreement or is deemed to be obligated to restore
                           pursuant to Regulations Section 1.704-1(b)(2)(ii)(c)
                           or the penultimate sentence of each of Regulations
                           Sections 1.704-2(i)(5) and 1.704-2(g)(1); and

                  (ii)     such deficit shall be increased by the items
                           described in Regulations Section
                           1.704-1(b)(2)(ii)(d)(4), (5) and (6).

                  The foregoing definition of Adjusted Capital Account Deficit
is intended to comply with the provisions of Regulations Section
1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. A positive
balance in a Partner's Capital Account, after giving effect to the adjustments
described above in clauses (i) and (ii), is referred to in this Agreement as an
"Adjusted Capital Account Balance."

                  "Adjustment Date" means, with respect to any Capital
Contribution, the close of business on the Business Day last preceding the date
of the Capital Contribution, provided, that if such Capital Contribution is
being made by the General Partner in respect of the proceeds from the issuance
of REIT Shares (or the issuance of the General Partner's securities exercisable
for, convertible into or exchangeable for REIT Shares), then the Adjustment Date
shall be as of the close of business on the Business Day last preceding the date
of the issuance of such securities.

                  "Affiliate" means, with respect to any Person, any Person
directly or indirectly controlling, controlled by or under common control with
such Person. Control of any Person means the power to direct the management and
policies of such Person, directly or indirectly, whether through the ownership
of voting securities, by contract or otherwise, and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.

                  "Agreed Value" means (i) in the case of any Contributed
Property set forth in Exhibit A and as of the time of its contribution to the
Partnership, the Agreed Value of such property as set forth in Exhibit A; (ii)
in the case of any Contributed Property not set forth in Exhibit A and as of the
time of its contribution to the Partnership, the fair market value of such
property or other consideration as determined by the General Partner, reduced by
any liabilities either assumed by the Partnership upon such contribution or to
which such property is subject when contributed; and (iii) in the case of any
property distributed to a Partner by the Partnership, the fair market value of
such property as determined by the General Partner at the time such property is
distributed, reduced by any liabilities either assumed by such Partner upon such
distribution or to which such property is subject at the time of the
distribution as determined under Section 752 of the Code and the Regulations
thereunder.

                  "Agreement" means this Second Amended and Restated Agreement
of Limited Partnership, as it may be amended, modified, supplemented or restated
from time to time.

                                       2
<PAGE>

                  "Appraisal" means with respect to any assets, the opinion of
an independent third party experienced in the valuation of similar assets,
selected by the General Partner in good faith; such opinion may be in the form
of an opinion by such independent third party that the value for such property
or asset as set by the General Partner is fair, from a financial point of view,
to the Partnership.

                  "Assignee" means a Person to whom one or more Partnership
Units have been transferred in a manner permitted under this Agreement, but who
has not become a Substituted Limited Partner, and who has the rights set forth
in Section 11.5.

                  "Available Cash" means, with respect to any period for which
such calculation is being made,

                  (i)      the sum of:

                           a. the Partnership's Net Income or Net Loss (as the
                  case may be) for such period,

                           b. Depreciation and all other noncash charges
                  deducted in determining Net Income or Net Loss for such
                  period,

                           c. the amount of any reduction in reserves of the
                  Partnership referred to in clause (ii)(f) below (including,
                  without limitation, reductions resulting because the General
                  Partner determines such amounts are no longer necessary),

                           d. the excess of the net proceeds from the sale,
                  exchange, disposition, or refinancing of Partnership property
                  for such period over the gain (or loss, as the case may be)
                  recognized from any such sale, exchange, disposition, or
                  refinancing during such period (excluding any sale or other
                  disposition of all or substantially all of the assets of the
                  Partnership or a related series of transactions that, taken
                  together, result in the sale or other disposition of all or
                  substantially all of the assets of the Partnership), and

                           e. all other cash received by the Partnership for
                  such period that was not included in determining Net Income or
                  Net Loss for such period;

                  (ii)     less the sum of:

                           a. all principal debt payments made during such

of such asset, as determined by the contributing Partner and the General Partner
(as set forth on Exhibit A attached hereto, as such Exhibit may be amended from
time to time); provided, that if the contributing Partner is the General
Partner, then, except with respect to the General Partner's initial Capital
Contribution which shall be determined as set forth on Exhibit A, the

shall be adjusted to equal their respective gross fair market values, as
determined by the General Partner using such reasonable method of valuation as
it may adopt, provided, however, that for such purpose, the net value of all of
the Partnership assets, in the aggregate, shall be equal to the Deemed Value of

                           Partnership;

                  (ii)     the distribution by the Partnership to a Partner of

                           if the General Partner reasonably determines that
                           such adjustment is necessary or appropriate to
                           reflect the relative economic interests of the
                           Partners in the Partnership;

determination, by Appraisal.

Accounts pursuant to Regulations Section 1.704-1(b)(2)(iv)(m); provided,
however, that Gross Asset Values shall not be adjusted pursuant to this

business described in the foregoing clause (i) or to own interests in any entity
engaged, directly or indirectly, in any such business and (iii) to do anything
necessary or incidental to the foregoing, 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,

the conduct of the business of the Partnership. In connection with the
foregoing, and without limiting the General Partner's right in its sole

borrow money and issue evidences of indebtedness, whether or not secured by
mortgage, deed of trust, pledge or other lien, acquire, own, manage, improve and
develop real property, and lease, sell, transfer and dispose of real property;
provided, however, notwithstanding 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, 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.

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

obligations incurred pursuant to and as limited by the terms of this Agreement

registering the Partnership Units), (ii) a restrictive legend in the form set
forth in Exhibit D shall be placed on the certificates representing the
Partnership Units, and (iii) a notation shall be made in the appropriate records

exercise of options granted or delivery of REIT Shares pursuant to any Stock
Plan, in each case subject to the ownership limitations set forth in the General
Partner's Charter.

            (3) Upon request of the General Partner, it will disclose to the
General Partner the amount of REIT Shares or other shares of capital stock of

or withheld in its sole discretion, no Partner shall take any action that would
cause the Partnership at any time to have more than 100 partners (including as
partners those persons indirectly owning an interest in the Partnership through
a partnership, limited liability company, S

survive the execution and delivery of this Agreement by each Partner and the

acquisition of Properties) with any Person that is not

                                       20

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.    Issuance of Additional Partnership Interests. The General Partner,
in its sole and absolute discretion, 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 any other non-cash assets. In connection with any such additional
Capital Contributions (of cash or property), 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 Partner
Interests, all as shall be determined by the General Partner in its sole and
absolute discretion subject to Maryland 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 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) (1) 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.C 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.B, and (2) the General Partner shall make a Capital
Contribution to the Partnership in an amount equal to the net proceeds raised in
connection with such issuance, 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. The General
Partner's determination that consideration is adequate shall be conclusive
insofar as the adequacy of consideration relates to whether the Partnership
Interests are validly issued and paid. In the event that the Partnership issues
additional Partnership Interests pursuant to this Section 4.3.B, the General
Partner shall make such revisions to this Agreement (including but not limited
to the revisions described in Section 5.4, Section 6.2.C, and Section 8.6) as it
determines are necessary

                                       21
<PAGE>

to reflect the issuance of such additional Partnership Interests. Without
limiting the foregoing, the General Partner is expressly authorized to cause the
Partnership to issue Partnership Units for no tangible value or for less than
fair market value, so long as the General Partner concludes in good faith that
such issuance of Partnership Interests is in the best interests of the
Partnership.

      C.    Issuance of REIT Shares or Other Securities by the General Partner.
The General Partner shall not issue any additional REIT Shares, other shares of
capital stock of the General Partner or New Securities (other than REIT Shares
issued pursuant to Section 8.6 or such shares, stock or securities pursuant to a
dividend or distribution (including any stock split) to all of its stockholders
or all of its stockholders who hold a particular class of stock of the General
Partner) unless (i) the General Partner shall cause the Partnership to issue to
the General Partner, Partnership Interests or rights, options, warrants or
convertible or exchangeable securities of the Partnership having designations,
preferences and other rights, all such that the economic interests thereof are
substantially similar to those of the REIT Shares, other shares of capital stock
of the General Partner or New Securities issued by the General Partner and (ii)
the General Partner shall make a Capital Contribution of the net proceeds 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. Without
limiting the foregoing, the General Partner is expressly authorized to issue
REIT Shares, other shares of capital stock of the General Partner or New
Securities for no tangible value or for less than fair market value, and the
General Partner is expressly authorized to cause the Partnership to issue to the
General Partner corresponding Partnership Interests, so long as (x) the General
Partner concludes in good faith that such issuance of Partnership Interests is
in the interests of the Partnership; and (y) the General Partner contributes all
proceeds, if any, from such issuance and exercise to the Partnership.

            In connection with the General Partner's initial public offering of
REIT Shares, any other issuance of REIT Shares, other capital stock of the
General Partner or New Securities, the General Partner shall contribute to the
Partnership, any net proceeds raised in connection with such issuance; provided,
that the General Partner may use a portion of the net proceeds from any offering
to acquire Partnership Units or other assets (provided such other assets are
contributed to the Partnership pursuant to the terms of this Agreement; and
provided further that if the net proceeds actually received by the General
Partner are less than the gross proceeds of such issuance as a result of any
underwriter's discount or other expenses paid or incurred in connection with
such issuance then, except to the extent such net proceeds are used to acquire
Partnership Units, the General Partner shall be deemed to have made a Capital
Contribution to the Partnership in the amount equal to the sum of the net
proceeds of such issuance plus the amount of such underwriter's discount and
other expenses paid by the General Partner (which discount and expense shall be
treated as an expense for the benefit of the Partnership for purposes of Section
7.4). In the case of issuances of REIT Shares, other capital stock of the
General Partner or New Securities pursuant to any Stock Plan at a discount from
fair market value or for no value, the amount of such discount representing
compensation to the employee, as determined by the General Partner, shall be
treated as an expense for the benefit of the Partnership for purposes of Section
7.4 and, as a result, the General Partner shall be deemed to have made a Capital
Contribution to the Partnership in an amount equal to the sum of any net
proceeds of such issuance plus the amount of such expense.

                                       22
<PAGE>

      D.    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 in such class or series of Partnership Units shall be equal to a
fraction, the numerator of which is equal to the amount of cash and the Agreed
Value of the Property contributed as of the time such 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) and (ii) the aggregate Agreed Value of additional Capital
Contributions contributed by all Partners and/or third parties to the
Partnership on such Adjustment Date in 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) and (ii) the Agreed Value of
additional Capital Contributions, if any, made by such Partner to the
Partnership in such class or series of Partnership Interests as of such
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 Agreed Value of additional Capital Contributions contributed by all
Partners and/or third parties to the Partnership on such Adjustment Date in such
class or series. Provided, however, solely for purposes of calculating a
Partner's Percentage Interest pursuant to this Section 4.3.D, (i) in the case of
cash Capital Contributions by the General Partner funded by an offering of REIT
Shares or other shares of capital stock of the General Partner and (ii) in the
case of the contribution of properties by the General Partner which were
acquired by the General Partner in exchange for REIT Shares or other shares of
capital stock of the General Partner immediately prior to such contribution, the
General Partner shall be issued a number of Partnership Units equal and
corresponding to the number of such shares issued by the General Partner in
exchange for such cash or 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.

Section 4.4 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 at the time of
admission 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 agreements with the Partnership, in the form of a
guarantee or contribution agreement, which have the effect of providing a
guarantee of certain obligations of the Partnership.

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

                                       23
<PAGE>

to (i) providing funds to the Partnership or (ii) issuance or sale of any
Partnership Units or other Partnership Interests.

                                   ARTICLE 5.

                                  DISTRIBUTIONS

Section 5.1 Requirement and Characterization of Distributions

            The General Partner shall cause the Partnership to distribute
quarterly all, or such portion as the General Partner may in its discretion
determine, Available Cash generated by the Partnership to the Partners who are
Partners on the applicable Partnership Record Date with respect to such
distribution, (1) first, with respect to any class or series of Partnership
Interests that are entitled to any preference in distributions, in accordance
with the rights of such class or series of Partnership Interests (and within
such class or series, pro rata in proportion to the respective Percentage
Interests on the applicable Partnership Record Date), and (2) second, with
respect to any class or series of Partnership Interests that are not entitled to
any preference in distributions, pro rata to each such class or series in
accordance with the terms of such class or series to the Partners who are
Partners of such class or series on the Partnership Record Date with respect to
such distribution (and within each such class or series, pro rata in proportion
to the respective Percentage Interests on such Partnership Record Date). Unless
otherwise expressly provided for herein or in an agreement, if any, entered into
in connection with the creation of a new class or series of Partnership
Interests created 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 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 the
imposition of any federal income or excise tax liability on the General Partner.

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.

Section 5.3 Distributions Upon Liquidation

            Notwithstanding Section 5.1, proceeds from a Liquidating Event 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 to the General Partner or any Additional Limited Partner pursuant to
Section 4.3.B or 4.3.C, the

                                       24
<PAGE>

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 period 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 period, and the denominator of which is the total
number of days in such period.

                                   ARTICLE 6.

                                   ALLOCATIONS

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 Partnership 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.    Allocation of Net Income and Net Losses.
            ---------------------------------------

            (1) Net Income. Except as otherwise provided in Section 6.3, Net
Income for any Partnership Year shall be allocated to the Partners in the
following manner and order of priority:

                (a) First, to the General Partner in an amount equal to the
remainder, if any, of the cumulative Net Losses allocated to the General Partner
pursuant to Section 6.2.A.2(c) for all prior Partnership Years minus the
cumulative Net Income allocated to the General Partner pursuant to this Section
6.2.A.(1)(a) for all prior Partnership Years;

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

                (c) Third, to the General Partner and the Limited Partners in
proportion, and in an amount equal, to the remainder, if any, of the cumulative
Net Losses allocated to each such Partner pursuant to Section 6.2.A.2(a) for all
prior Partnership Years minus the cumulative Net Income allocated to each
Partner pursuant to this Section 6.2.A.(1)(c) for all prior Partnership Years;

                (d) Fourth, to each of the Partners in accordance with their
respective Percentage Interests.

            To the extent the allocations of Net Income set forth above in any
paragraph of this Section 6.2.A.(1) are not sufficient to entirely satisfy the
allocation set forth in such

                                       25
<PAGE>

paragraph, such allocation shall be made in proportion to the total amount that
would have been allocated pursuant to such paragraph without regard to such
shortfall.

            (2) Net Losses. Except as otherwise provided in Section 6.3, Net
Losses for any Partnership Year shall be allocated to the Partners in the
following manner and order of priority:

                (a) First, to the General Partner and the Limited Partners in
accordance with their respective Percentage Interests (to the extent consistent
with this Section 6.2.A(2)(a)) until the Adjusted Capital Account Balance
(ignoring for this purpose any amounts a Partner is obligated to contribute to
the capital of the Partnership or is deemed obligated to contribute pursuant to
Regulations Section 1.704-1(b)(2)(ii)(c)(2)) of each such Partner is zero;

                (b) Second, to the Limited Partners to the extent of, and in
proportion to, their Adjusted Capital Account Balance; and

                (c) Third, to the General Partner.

      B.    Allocations to Reflect Issuance of Additional Partnership Interests.
In the event that the Partnership issues additional Partnership Interests to the
General Partner, a Limited Partner or any Additional Limited Partner pursuant to
Section 4.3, the General Partner shall make such revisions to this Section 6.2
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 in accordance with any method selected
by the General Partner.

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 Partnership Year, each Holder shall be
specially allocated items of Partnership income and gain for such year (and, if
necessary, subsequent years) in an amount equal to such Holder'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 Holder
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

                                       26
<PAGE>

Partner Minimum Gain attributable to a Partner Nonrecourse Debt during any
Partnership Year, each Holder 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 Holder'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 Holder 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 Partnership Year shall be
specially allocated to the Holders in accordance with their respective
Percentage Interests. Any Partner Nonrecourse Deductions for any Partnership
Year shall be specially allocated to the Holder(s) who bears the economic risk
of loss with respect to the Partner Nonrecourse 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 Holder 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 Holder in an amount and manner sufficient to
eliminate, to the extent required by such Regulations, the Adjusted Capital
Account Deficit of the Holder 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 Holder 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 this 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 Holder has a
deficit Capital Account at the end of any Partnership Year which is in excess of
the sum of (1) the amount (if any) such Holder is obligated to restore to the
Partnership, and (2) the amount such Holder 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
Holder 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 Holder 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 this Agreement.

                                       27
<PAGE>
                        (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 Holder, such allocation of Net Loss shall be reallocated among
the other Holders in accordance with their respective Percentage Interests,
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 Holder 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 Holders 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 Holders 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 Holders so that, to the extent possible, the
net amount of such allocations of other items and the Regulatory Allocations to
each Holder shall be equal to the net amount that would have been allocated to
each such Holder if the Regulatory Allocations had not occurred.

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

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 Holders 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 Holders
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 contributed to the Partnership in
connection with the General Partner's initial public offering, 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 other properties contributed to the Partnership, the Partnership
shall account for such variation under any method consistent with Section 704(c)
of

                                       28
<PAGE>
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 (b) 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 Section 704(c) of
the Code and the applicable regulations as chosen by the General Partner,
provided, however, that the "traditional method" as described in Regulations
Section 1.704-3(b) shall be used with respect to Partnership Property that is
contributed to the Partnership in connection with the General Partner's initial
public offering.

                                   ARTICLE 7.
                      MANAGEMENT AND OPERATIONS OF BUSINESS

Section 7.1       Management

      A. Except as otherwise expressly provided in this Agreement, all
management powers over the business and affairs of the Partnership are and shall
be exclusively vested in the General Partner, and no Limited Partner shall have
any right to participate in or exercise control or management power over the
business and affairs of the Partnership. The General Partner may not be removed
by the Limited Partners with or without cause, except with the consent of the
General Partner. In addition to the powers now or hereafter granted a general
partner of a limited partnership under applicable law or which are granted to
the General Partner under any other provision of this Agreement, the General
Partner, subject to the other provisions hereof including Sections 7.3 and 11.2,
shall have full power and authority to do all things deemed necessary or
desirable by it to conduct the business of the Partnership (including, without

Limited Partner or otherwise, which amendment and restatement, notwithstanding
anything in this Agreement to the contrary, shall not be deemed an amendment to
this Agreement, as long as the matter or event being reflected in Exhibit A
hereto otherwise is authorized by this Agreement;

      B. Each of the Limited Partners agrees that the General Partner is

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 or 11.2), the Act or any applicable law, rule
or regulation to the fullest extent permitted under the Act or other 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 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 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. Each of the Limited Partners acknowledges that, in exercising its
authority under this Agreement, the General Partner may, but shall be under no
obligation to, take into account the tax consequences to any Partner (including
the General Partner) of any action taken (or not taken) by the General Partner.
The General Partner and the Partnership shall not have liability to a Partner
under this Agreement as a result of any income tax liability incurred by a
Limited

                                       32
<PAGE>
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 Maryland
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(4), 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 liability) in the State
of Maryland, 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 an
express prohibition or limitation of this Agreement without the written Consent
of the Limited Partners and may not (i) 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 (ii) enter into
any contract, mortgage, loan or other agreement (other than that certain
Revolving Loan Agreement dated as of August 2004 by and among the Company, the
Partnership, the other borrowers and lenders party thereto, U.S. Bank National
Association, as Administrative Agent, Lead Arranger and Swing Loan Bank, Keybank
National Association, as Syndication Agent, and Royal Bank of Canada, as
Documentation Agent, as amended from time to time) 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 in each case 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), or except as provided in Section 7.3.C, amend, modify
or terminate this Agreement.

                                       33
<PAGE>
      C. Notwithstanding Section 7.3.B, the General Partner shall have the
exclusive power to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

            (1) 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;

            (2) to reflect the issuance of additional Partnership Interests
pursuant to Sections 4.3.B, 5.4 and 6.2B. or the admission, substitution,
termination, or withdrawal of Partners in accordance with this Agreement (which
may be effected through the replacement of Exhibit A with an amended Exhibit A);

            (3) 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;

            (4) 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, correct or supplement any provision in this Agreement not
inconsistent with law or with other provisions, 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;

            (5) to satisfy any requirements, conditions, or guidelines contained
in any order, directive, opinion, ruling or regulation of a federal or state
agency or contained in federal or state law;

            (6) 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;

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

            (8) to amend or modify any provision of this Agreement in connection
with a Termination Transaction.

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

      D. Notwithstanding Sections 7.3.B and 7.3.C, this Agreement shall not be
amended with respect to any Partner adversely affected, and no action may be
taken by the General Partner, without the Consent of such 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 or Section 13.2.A(4), or the allocations
specified in Article 6 (except as permitted pursuant to Sections 4.3, 5.4, 6.2.B
and Section 7.3.C(3)), (iv) materially alter or modify the rights to a
Redemption or the REIT Shares Amount as set forth in Section 8.6, and related

                                       34
<PAGE>
definitions hereof, or (v) amend this Section 7.3.D. Further, no amendment may
alter the restrictions on the General Partner's authority set forth elsewhere in
this Section 7.3 or in Section 11.2.B without the Consent specified in such
section. This Section 7.3.D does not require unanimous consent of all Partners
adversely affected unless the amendment is to be effective against all partners
adversely affected.

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. The Partnership shall be responsible for and shall pay all expenses
relating to the Partnership's and the General Partner's organization, the
ownership of its assets and its operations. The General Partner is hereby
authorized to pay compensation for accounting, administrative, legal, technical,
management and other services rendered to the Partnership. Except to the extent
provided in this Agreement, the General Partner and its Affiliates 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 that the General
Partner and its Affiliates incur relating to the ownership and operation of, or
for the benefit of, the Partnership (including, without limitation,
administrative expenses); provided, that the amount of any such reimbursement
shall be reduced by any interest earned by the General Partner with respect to
bank accounts or other instruments or accounts held by it on behalf of the
Partnership. The Partners acknowledge that all such expenses of the General
Partner are deemed to be for the benefit of the Partnership. Such reimbursement
shall be in addition to any reimbursement made as a result of indemnification
pursuant to Section 7.7 hereof. In the event that certain expenses are incurred
for the benefit of the Partnership and other entities (including the General
Partner), such expenses will be allocated to the Partnership and such other
entities in such a manner as the General Partner in its sole and absolute
discretion deems fair and reasonable. All payments and reimbursements hereunder
shall be characterized for federal income tax purposes as expenses of the
Partnership incurred on its behalf, and not as expenses of the General Partner.

      C. If the General Partner shall elect to purchase from its stockholders
REIT Shares for the purpose of delivering such REIT Shares to satisfy an
obligation under any dividend reinvestment program adopted by the General
Partner, any employee stock purchase plan adopted by the General Partner, or any
similar obligation or arrangement undertaken by the General Partner in the
future or for the purpose of retiring such REIT Shares, the purchase price paid
by the General Partner for such REIT Shares and any other expenses incurred by
the General Partner in connection with such purchase shall be considered
expenses of the Partnership and shall be advanced to the General Partner or
reimbursed to the General Partner, subject to the condition that: (i) if such
REIT Shares subsequently are sold by the General Partner, the General Partner
shall pay to the Partnership any proceeds received by the General Partner for
such REIT Shares (which sales proceeds shall include the amount of dividends
reinvested under any dividend reinvestment or similar program; provided, that a
transfer of REIT Shares for Partnership Units pursuant to Section 8.6 would not
be considered a sale for such purposes); and (ii) if such REIT Shares are not
retransferred by the General Partner within thirty

                                       35
<PAGE>
(30) days after the purchase thereof, or the General Partner otherwise
determines not to retransfer such REIT Shares, the General Partner, shall cause
the Partnership to redeem a number of Partnership Units held by the General
Partner equal to the number of such REIT Shares, as adjusted (x) pursuant to
Section 7.5 (in the event the General Partner acquires material assets, other
than on behalf of the Partnership) and (y) for stock dividends and
distributions, stock splits and subdivisions, reverse stock splits and
combinations, distributions of rights, warrants or options, and distributions of
evidences of indebtedness or assets relating to assets not received by the
General Partner pursuant to a pro rata distribution by the Partnership (in which
case such advancement or reimbursement of expenses shall be treated as having
been made as a distribution in redemption of such number of Partnership Units
held by the General Partner).

      D. As set forth in Section 4.3, the General Partner shall be treated as
having made a Capital Contribution in the amount of all expenses that it incurs
relating to the General Partner's offering of REIT Shares, other shares of
capital stock of the General Partner or New Securities.

      E. 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 minority interest in any
Subsidiary Partnership(s) 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 or maintain an
interest of 1% or less in the capital of such partnership, and the General
Partner may acquire such cash from the Partnership as a loan or in exchange for
a reduction in the General Partner's Partnership 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 or other assets in exchange for REIT
Shares or cash, to the extent such Properties or other assets are immediately
contributed by the General Partner to the Partnership, pursuant to the terms
described in Section 4.3.D. 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

                                       36
<PAGE>
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. The General Partner may also own one hundred percent
(100%) of the stock or interests of one or more Qualified REIT Subsidiaries or
limited liability companies, respectively, provided that any such entity shall
be subject to the limitations of this Section 7.5.A. If, at any time, the
General Partner acquires material assets (other than Partnership Interests or
other assets 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 determined by the General Partner, 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.

      B. In the event the General Partner exercises its rights under the Charter
to purchase REIT Shares, other capital stock of the General Partner or New
Securities, as the case may be, then the General Partner shall cause the
Partnership to purchase from it a number of Partnership Units equal to the
number of REIT Shares, other capital stock of the General Partner or New
Securities, as the case may be, so purchased on the same terms that the General
Partner purchased such REIT Shares, other capital stock of the General Partner
or New Securities, as the case may be.

Section 7.6       Contracts with Affiliates

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

      B. Except as provided in Section 7.5.A, the Partnership may transfer
assets to joint ventures, other partnerships, corporations or other business
entities in which it is or thereby becomes a participant upon such terms and
subject to such conditions consistent with this Agreement and applicable law as
the General Partner in its sole discretion deems advisable.

      C. 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 any Stock
Plan or any similar or successor plan and to repurchase such

                                       37
<PAGE>
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.

      D. Except as expressly permitted by this Agreement, neither the General
Partner nor any of its Affiliates shall sell, transfer or convey any property
to, or purchase any property from, the Partnership, directly or indirectly,
except pursuant to transactions that are determined by the General Partner in
good faith to be fair and reasonable.

      E. The General Partner is expressly authorized to enter into, in the name
and on behalf of the Partnership, a right of first opportunity arrangement and
other conflict avoidance agreements with various Affiliates of the Partnership
and the General Partner, on such terms as the General Partner, in its sole and
absolute discretion, believes are advisable.

Section 7.7       Indemnification

      A. To the fullest extent permitted by law, 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, fraud 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 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, settlement, conviction or upon a plea of nolo
contendere or its equivalent, or any entry of an order of probation prior to
judgment, does not create a presumption that the Indemnitee did not meet the
requisite standard of conduct set forth 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, except to the extent otherwise expressly
agreed to by such Partner and the Partnership.

      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

                                       38
<PAGE>
Partnership as authorized in this Section 7.7 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 unless otherwise provided in a written agreement pursuant to which
such Indemnitee is indemnified.

      D. The Partnership may, but shall not be obligated to, 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 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 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

                                       39
<PAGE>
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 10-107 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 nor any of its officers, directors, agents or
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. 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. If
there is a conflict between the interests of the stockholders of the General
Partner on one hand and the Limited Partners on the other, the General Partner
shall endeavor in good faith to resolve the conflict in a manner not adverse to
either the stockholders of the General Partner or the Limited Partners;
provided, however, that for so long as the General Partner, owns a controlling
interest in the Partnership, any such conflict that cannot be resolved in a
manner not adverse to either the stockholders of the General Partner or the
Limited Partners shall be resolved in favor of the stockholders. The General
Partner shall not be liable under this Agreement to the Partnership or to any
Partner for monetary damages for losses sustained, liabilities incurred, or
benefits not derived by Limited Partners in connection with such decisions;
provided, that the General Partner has acted in good faith.

      C. Subject to its obligations and duties as General Partner set forth in
Section 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.

                                       40
<PAGE>
      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 employee's liability 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) avoid the
General Partner incurring any taxes under Section 857 or Section 4981 of the
Code, is expressly authorized under this Agreement and is deemed approved by all
of the Limited Partners.

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 held by the General Partner for the use and

                                       41
<PAGE>
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.

                                   ARTICLE 8.
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

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,
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

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

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 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 Person.

Section 8.4       Return of Capital

            Except pursuant to the rights of Redemption set forth in Section
8.6, no Limited Partner shall be entitled to the withdrawal or return of his or
her Capital Contribution, except to the extent of distributions made pursuant to
this Agreement or upon termination of the Partnership as provided herein. No
Limited Partner or 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, or 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 such Limited Partner's expense:

            (1) 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;

            (2) to obtain a copy of the Partnership's federal, state and local

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

            (4) to obtain a copy of this Agreement and the Certificate and all
amendments thereto, together with executed copies of all powers of attorney

                                       43
<PAGE>
            (5) 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 Limited Partner in writing of any
adjustment made in the calculation of the REIT Shares Amount within a reasonable
time after 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       Redemption Rights

      A. On or after (i) the first anniversary of the Effective Date, with
respect to the Partnership Units acquired on or contemporaneously with the
Effective Date, or (ii) the date of issuance of any other Partnership Units, or
on or after such later date as expressly provided in an agreement entered into
between the Partnership and any Limited Partner, each 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 Partnership Units held by such 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 Partnership Units do
not provide that such Partnership Units are not entitled to a right of
Redemption. Unless otherwise expressly provided in this Agreement or in a
separate agreement entered into between the Partnership and the holders of such
Partnership Units, all Partnership Units shall be entitled to a right of
Redemption hereunder. The Tendering Partner shall have no right, with respect to
any Partnership Units so redeemed, to receive any distributions paid on or after
the Specified Redemption Date. Any Redemption shall be exercised pursuant to a
Notice of Redemption delivered to the General Partner by the Limited Partner who
is exercising the right (the "Tendering Partner"). The Cash Amount shall be
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 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 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

                                       44
<PAGE>
withdraw its redemption request at any time prior to the acceptance of the cash
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. Notwithstanding any delay in such delivery (but subject to Section
8.6.E), 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. In addition, the REIT
Shares for which the Partnership Units might be exchanged shall also bear a
legend which generally provides the following:

            THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO RESTRICTIONS ON BENEFICIAL AND CONSTRUCTIVE OWNERSHIP AND TRANSFER
FOR THE PURPOSE OF THE CORPORATION'S MAINTENANCE OF ITS STATUS AS A REAL ESTATE
INVESTMENT TRUST ("REIT") UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED
(THE "CODE"). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY
PROVIDED IN THE CORPORATION'S ARTICLES OF AMENDMENT AND RESTATEMENT, (i) NO
PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE CORPORATION'S COMMON
STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF SHARES, WHICHEVER IS MORE
RESTRICTIVE) OF THE OUTSTANDING COMMON STOCK OF THE CORPORATION; (ii) NO PERSON
MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF COMMON STOCK THAT WOULD RESULT
IN THE CORPORATION BEING "CLOSELY HELD" UNDER SECTION 856(h) OF THE CODE OR
OTHERWISE CAUSE THE CORPORATION TO FAIL TO QUALIFY AS A REIT; AND (iii) NO
PERSON MAY TRANSFER SHARES OF COMMON STOCK IF SUCH TRANSFER WOULD RESULT IN THE
CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS. ANY
PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS, OR ATTEMPTS TO BENEFICIALLY OR
CONSTRUCTIVELY OWN, SHARES OF COMMON STOCK IN VIOLATION OF THE ABOVE LIMITATIONS
MUST IMMEDIATELY NOTIFY THE CORPORATION. IF ANY OF THE RESTRICTIONS ON TRANSFER
OR OWNERSHIP ARE VIOLATED, THE SHARES OF COMMON STOCK REPRESENTED HEREBY WILL BE
AUTOMATICALLY TRANSFERRED TO THE TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR
MORE CHARITABLE BENEFICIARIES. IN ADDITION, THE CORPORATION MAY REDEEM SHARES
UPON THE TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE
DISCRETION IF THE BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A TRANSFER OR
OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE. FURTHERMORE, UPON THE
OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED TRANSFERS IN VIOLATION OF THE
RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO. ALL TERMS IN THIS LEGEND
THAT ARE DEFINED IN THE ARTICLES OF AMENDMENT AND RESTATEMENT OF THE CORPORATION
SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE ARTICLES OF AMENDMENT AND
RESTATEMENT OF THE CORPORATION, AS THE

                                       45
<PAGE>
SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE
RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF
SHARES OF COMMON STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY
MAY BE DIRECTED TO THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE.

      D. Each 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 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 Limited Partner shall assume and pay such
transfer tax.

      E. Notwithstanding the provisions of Section 8.6.A, 8.6.B, 8.6.C or any
other provision of this Agreement, a 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 could 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 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 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), with respect to any Redemption or exchange for REIT Shares pursuant to
this Section 8.6:

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

            (2) Without the consent of the General Partner, each Limited Partner
may not effect a Redemption for less than 1,000 Partnership Units or, if the
Limited Partner holds less than 1,000 Partnership Units, all of the Partnership
Units held by such Limited Partner.

            (3) Without the consent of the General Partner, each 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 stockholders of some or all of its
portion of such distribution.

            (4) 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.

                                       46
<PAGE>
            (5) Each Tendering Partner shall continue to own all Partnership
Units subject to any Redemption or exchange for REIT Shares, and be treated as a
Limited Partner with respect to such Partnership Units for all purposes of this
Agreement, until such Partnership Units are transferred to the General Partner
and paid for or exchanged on 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 Partnership Units.

      G. In the event that the Partnership issues additional Partnership
Interests to any Additional Limited Partner pursuant to Section 4.3.B, 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.

      H. Notwithstanding any other provision of this Agreement, the General
Partner is authorized to take any action that it determines to be necessary or
appropriate to cause the partnership to comply with any withholding requirements
established under the Code or any other federal, state or local law that apply
upon a Redemption or exchange of Tendered Units. If a Tendering Partner believes
that it is exempt from withholding upon a Redemption or exchange of Tendered
Units, such Partner must furnish the General Partner a FIRPTA certificate or
other documentation requested by the General Partner is a form acceptable to the
General Partner. If the Partnership or the General Partner is required to
withhold and pay over to any taxing authority any amount upon a Redemption or
exchange of Tendered Units and the Cash Amount or the REIT Shares Amount, as the
case may be, equals or exceeds the amount of tax required to be withheld, the
amount withheld shall be treated as an amount received by such Partner in
redemption of its Tendered Units. If the Cash Amount or the REIT Shares Amount,
as the case may be, is less than the amount of tax required to be withheld, the
Tendering Partner shall not receive any Cash Amount or REIT Shares Amount, and
the Tendering Partner shall contribute the excess of the amount of tax required
to be withheld over the Cash Amount or REIT Shares Amount before such excess
taxes are required to be paid to the taxing authority.

Section 9.1       Records and Accounting

            The General Partner shall keep or cause to be kept at the 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 any information storage device,
provided, that the records so maintained are convertible into clearly legible
written form within a reasonable period of time. The books of the Partnership
shall be maintained, for financial and tax reporting purposes, on an accrual
basis in accordance with generally accepted accounting principles.

Section 9.2       Fiscal Year

            The fiscal year of the Partnership shall be the calendar year.

Section 9.3       Reports

      A. As soon as practicable, but in no event later than 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 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 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 interest 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 applicable state income tax
purposes and shall use all reasonable efforts to furnish, within 90 days of the
close of each taxable year, the tax information reasonably required by Limited
Partners for federal and applicable state income tax reporting purposes. Each
Limited Partner shall promptly provide the General Partner with any information
reasonably requested by the General Partner relating to any Contributed Property
contributed (directly or indirectly) 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

                                       48
<PAGE>
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 6230(e) 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:

            (1) 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 (i) 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 (ii) 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);

            (2) 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;

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

            (4) 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;

            (5) 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

            (6) 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.

                                       49
<PAGE>
            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.

      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 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
receivable of the Partnership from such Limited Partner, which receivable shall
be paid by such Limited Partner within 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. 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 a
Partner purports to assign its 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.
The term "transfer" when used in this Article 11 does not include any Redemption
or exchange for REIT Shares pursuant to Section 8.6, except as otherwise
provided herein. 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 or consented to by
the General Partner.

      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 to by the General Partner in its sole and absolute
discretion.

Section 11.2      Transfer of General Partner's Partnership Interest

      A. Except in connection with a Termination Transaction permitted under
Section 11.2.B, 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 or consolidation, liquidation or otherwise),
other than to an Affiliate, without the Consent of the Limited Partners, which
may be given or withheld by each Limited Partner in his, her or its sole and
absolute discretion, and only upon the admission of a successor General Partner
pursuant to Section 12.1. 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 obligations under this Agreement without the Consent of the Limited
Partners, in their reasonable discretion. In the event the General Partner
withdraws from the Partnership in violation of this Agreement or otherwise, 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.

                                       51
<PAGE>
      B. The General Partner shall not engage in any merger, consolidation or
other combination with or into another person, sale of all or substantially all
of its assets or any reclassification, recapitalization or change of its
outstanding equity interests ("Termination Transaction") unless either clause
(a) or (b) below is satisfied:

                  (a) in connection with such Termination Transaction all
Limited Partners 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 Shares Amount and the greatest amount
of cash, securities or other property paid to a holder of one REIT Share in
consideration of one REIT Share at any time during the period commencing upon
and continuing after the date on which the Termination Transaction is
consummated; provided, that, if, in connection with the Termination Transaction,
a purchase, tender or exchange offer shall have been made to and accepted by the
holders of more than fifty percent (50%) of the outstanding REIT Shares, each
holder of Partnership Units shall receive, or shall 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 right 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 and
then such Termination Transaction shall have been consummated; or

                  (b) 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 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 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; and (iv) such rights of the
Limited Partners 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(2)(a); 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, such common equity securities,
with an exchange ratio based on the determination of relative fair market value
of such securities and the REIT Shares.

Section 11.3      Limited Partners' Rights to Transfer

      A. Prior to the first anniversary of the Effective Date, no Limited
Partner shall transfer all or any portion of its Partnership Interest to any
transferee without the consent of the General Partner, which consent may be
withheld in its sole and absolute discretion; provided, however, that any
Limited Partner may, at any time (whether prior to or after such one-year
period), 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

                                       52
<PAGE>
Interest to an Affiliate, another original Limited Partner 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, 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, and transfer such
pledged Partnership Interest to such lending institution in connection with the
exercise of remedies under such loan or extension or credit, and the transfer of
such pledged Partnership Interest by the lender to any transferee. After such
anniversary, each Limited Partner or Assignee (resulting from a transfer made
pursuant to clauses (i)-(iv) of the proviso 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 (in addition to the right of each such Limited Partner or
Assignee to continue to make any such transfer permitted by clauses (i)-(iv) of
such proviso without satisfying either of the following conditions):

            (1) 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 (i) the identity of the proposed transferee, and (ii) 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.

            (2)   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, and to the representations 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

                                       53
<PAGE>
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
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.

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). The General Partner shall, however, have the right to consent to
the admission of a transferee of the interest of a Limited Partner pursuant to
this Section 11.4 as a Substituted Limited Partner, 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, whether at law or in equity, 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 General
Partner 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.

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

                                       54
<PAGE>
of Redemption provided in Section 8.6, 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 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
Partnership Units being admitted to the Partnership as a Substituted Limited
Partner or (ii) pursuant to the exercise of its right of Redemption of all of
such Limited Partner's Partnership Units under Section 8.6; provided that after
such transfer, exchange or redemption such Limited Partner owns no Partnership
Interest.

      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 shall cease to be a Limited Partner;
provided that after such transfer, exchange or redemption such Limited Partner
owns no Partnership Interest.

      C. Transfers pursuant to this Article 11 may only be made on the first day
of a fiscal quarter of the Partnership, unless the General Partner otherwise
agrees.

      D. If any Partnership Interest is transferred, assigned or redeemed during
any quarterly segment of the Partnership's Partnership Year in compliance with
the provisions of this Article 11 or transferred or redeemed pursuant to Section
8.6, on any day other than the 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 Partnership Year shall be divided and allocated
between the transferor Partner and the transferee Partner by taking into account
their varying interests during the Partnership Year using a method selected by
the General Partner that is in accordance with Section 706(d) of the Code.
Except as otherwise agreed by the General Partner, all distributions of
Available Cash with respect to which the Partnership Record Date is before the
date of such transfer, assignment, exchange or redemption shall be made to the
transferor Partner, and all distributions of Available Cash thereafter, in the
case of a transfer or assignment other than a redemption, shall be made to the
transferee Partner.

                                       55
<PAGE>
      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 pursuant to a Redemption or exchange for REIT Shares 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 could 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 of all Partnership Interests held by
all Limited Partners or pursuant to a transaction expressly permitted under
Section 11.2); (v) if in the opinion of counsel to the Partnership such transfer
could cause the Partnership to cease to be classified as a partnership for
federal income tax purposes (except as a result of the Redemption or exchange
for REIT Shares of all Partnership Interests held by all Limited Partners); (vi)
if such transfer could, in the opinion of counsel to the Partnership, 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 could, 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
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 (1) 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,
(2) could cause the Partnership to become a "publicly traded partnership," as
such term is defined in Sections 469(k)(2) or 7704(b) of the Code, (3) could be
in violation of Section 3.4.E(5), or (4) could cause the Partnership to fail one
or more of the Safe Harbors (as defined below); (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) except with the consent of the General Partner,
which may be given or withheld in its sole discretion, if the transferee or
assignee of such Partnership Interest is unable to make the representations set
forth in Section 3.4.C; (xii) if such transfer is 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, except with the consent of the General
Partner, which may be given or withheld in its sole and absolute discretion; and
provided, that, as a condition to granting such consent the lender may be
required to enter into an arrangement with the Partnership and the General
Partner to redeem or exchange for the REIT Shares Amount any Partnership Units
in which a security interest is held simultaneously with the time at which such
lender would be deemed to be a partner in the Partnership for purposes of
allocating liabilities to such lender under Section 752 of the Code; or (xiii)
if in the opinion of legal counsel for the Partnership such transfer could
adversely affect the ability of the General Partner to continue to qualify as a
REIT or, except with the consent of the

                                       56
<PAGE>
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 Partnership Units by the Partnership
or the General Partner) to determine (i) if such interests could be treated as
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 could result in the
Partnership being unable to qualify for the "safe harbors" set forth in
Regulations Section 1.7704-1 (or such other 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 the authority (but shall not be required) 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" within the meaning of Code Section
7704, or any recognition by the Partnership of such transfers, or to ensure that
one or more 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. After the admission to the Partnership of the initial Limited Partners
on the date hereof, 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.

      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

                                       57
<PAGE>
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 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 using a method selected by
the General Partner that is in accordance with Section 706(d) of the Code. All
distributions of Available Cash with respect to which the Partnership Record
Date is before the date of such admission shall be made solely to Partners and
Assignees other than the Additional Limited Partner (other than in its capacity
as an Assignee) and, except as otherwise agreed to by the Additional Limited
Partners and the General Partner, all distributions of Available Cash thereafter
shall be made to all Partners and Assignees including such Additional Limited
Partner.

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 (each a "Liquidating
Event"):

      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 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;

      C. subject to compliance with Section 11.2 an election to dissolve the
Partnership made by the General Partner, in its sole and absolute discretion;

                                       58
<PAGE>
      D. entry of a decree of judicial dissolution of the Partnership pursuant
to the provisions of the Act;

      E. any sale or other disposition of all or substantially all of the assets
of the Partnership or a related series of transactions that, taken together,
result in the sale or other disposition of all or substantially all of the
assets of the Partnership;

      F. the Incapacity of the General Partner, unless all of the remaining
Partners in their sole and absolute discretion agree in writing to continue the
business of the Partnership and to the appointment, effective as of a date prior
to the date of such Incapacity, of a substitute General Partner;

      G. the Redemption or exchange for REIT Shares of all Partnership Units
(other than those of the General Partner) pursuant to this Agreement; or

      H. a 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 the entry of such order or judgment all of the remaining Partners agree 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.

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 property 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 in the General Partner) shall be applied and distributed
in the following order:

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

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

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

            (4) The balance, if any, to the General Partner and Limited Partners
in accordance with their positive Capital Account balances, determined after
taking into account all

                                       59
<PAGE>
Capital Account adjustments for all prior periods and 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(4)).

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.

Section 13.3      Capital Contribution Obligation

            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 at any time shall not
be considered a debt owed to the Partnership or to any other Person for any
purpose whatsoever, except to the extent otherwise expressly agreed to by such
Partner and the Partnership.

Section 13.4      Compliance with Timing Requirements of Regulations

            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:

            (1) 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

                                       60
<PAGE>
            (2) withheld or escrowed to provide a reasonable reserve for
Partnership liabilities (contingent or otherwise) and to reflect the unrealized
portion of any installment obligations owed to the Partnership, provided, that
such withheld or escrowed amounts shall be distributed to the General Partner
and Limited Partners in the manner and priority set forth in Section 13.2.A as
soon as practicable.

Section 13.5      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 contributed all of its assets
and liabilities to a new partnership in exchange a for an interest in the new
partnership. Immediately thereafter, the Partnership shall be deemed to
distribute interests in the new partnership to the General Partner and Limited
Partners in proportion to their respective interests in the Partnership in
liquidation of the Partnership.

Section 13.6      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. No Limited Partner shall have priority over any other
Limited Partner as to the return of his Capital Contributions, distributions or
allocations.

Section 13.7      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 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 13.8      Cancellation of Certificate of Limited Partnership

            Upon the completion of the liquidation of the Partnership cash and
property as provided in Section 13.2, the Partnership shall be terminated and
the Certificate and all qualifications of the Partnership as a foreign limited
partnership in jurisdictions other than the State of Maryland shall be cancelled
and such other actions as may be necessary to terminate the Partnership shall be
taken.

Section 13.9      Reasonable Time for Winding-Up

            A reasonable time shall be allowed for the orderly winding-up of the
business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2, in order to

                                       61
<PAGE>
minimize any losses otherwise attendant upon such winding-up, and the provisions
of this Agreement shall remain in effect between the Partners during the period
of liquidation.

Section 13.10     Waiver of Partition

            Each Partner hereby waives any right to partition of the Partnership
property.

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 to the Limited Partners, as applicable.
The General Partner shall seek the written consent 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 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) with respect to the proposal; 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 Limited Partners. The notice 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 30 days prior to the date of
such meeting. Partners may vote in person or by proxy at such meeting. Whenever
the vote or Consent of the Limited Partners or of the 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 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.

                                       62
<PAGE>
      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 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.

                        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
(defined below) 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 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 (10) percent 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 to 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 (10) percent 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

                                      C-1
<PAGE>
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.

                               REGISTRATION RIGHTS

            SECTION 2.1. Shelf Registration. Commencing on or after the first
anniversary of the consummation date of the Initial Public Offering, the Company
shall prepare and file a "shelf" registration statement with respect to the
Registrable Securities on an appropriate form for an offering to be made on a
continuous basis pursuant to Rule 415 under the Securities Act (the "Shelf
Registration Statement") and shall use its commercially reasonable efforts to
cause the Shelf Registration Statement to be declared effective on or as soon as
practicable thereafter, and to keep such Shelf Registration Statement
continuously effective for a period ending when all shares of Common Stock
covered by the Shelf Registration Statement are no longer Registrable
Securities. In the event that the Company fails to file, or if filed fails to
maintain the effectiveness of, a Shelf Registration Statement, Holders of
Registrable Securities may make a written request for a Demand Registration (as
defined below) pursuant to Section 2.2 herein or participate in a Piggy Back
Registration (as defined below) pursuant to Section 2.3 herein; provided,
further, that if and so long as a Shelf Registration Statement is on file and
effective, then the Company shall have no obligation to effect a Demand
Registration or allow participation in a Piggy Back Registration.

            SECTION 2.2. Demand Registration.

                  (a) Request for Registration. Subject to Section 2.1 hereof,
commencing on or after the first anniversary of the consummation date of the
Initial Public Offering, Holders of Registrable Securities may make a written
request for registration under the Securities Act of all or part of its or their
Registrable Securities (a "Demand Registration"); provided, that the Company
shall not be obligated to effect more than one Demand Registration

                                       4
<PAGE>
in any twelve month period; and provided, further, that the number of shares of
Registrable Securities proposed to be sold by the Holders making such written
request shall have a Market Value of at least $1,000,000. Any such request will
specify the number of shares of Registrable Securities proposed to be sold and
will also specify the intended method of disposition thereof. Within ten (10)
days after receipt of such request, the Company will give written notice of such
registration request to all other Holders of the Registrable Securities and
include in such registration all such Registrable Securities with respect to
which the Company has received written requests for inclusion therein within
twenty (20) Business Days after the receipt by the applicable Holder of the
Company's notice. Each such request will also specify the number of shares of
Registrable Securities to be registered and the intended method of disposition
thereof. Unless the Holder or Holders of a majority of the Registrable
Securities to be registered in such Demand Registration shall consent in
writing, no other party, including the Company (but excluding another Holder of
a Registrable Security), shall be permitted to offer securities under any such
Demand Registration.

                  (b) Effective Registration. A registration will not count as a
Demand Registration until it has become effective.

                  (c) Selling Holders Become Party to Agreement. Each Holder
acknowledges that by asserting or participating in its registration rights
pursuant to this Article II, he or she may become a Selling Holder and thereby
will be deemed a party to this Agreement and will be bound by each of its terms.

                  (d) Priority on Demand Registrations. If the Holders of a
majority of shares of the Registrable Securities to be registered in a Demand
Registration so elect by written notice to the Company, the offering of such
Registrable Securities pursuant to such Demand Registration shall be in the form
of an underwritten offering. The Company shall select the book-running managing
Underwriter in connection with any such Demand Registration; provided that such
managing Underwriter must be reasonably satisfactory to the Holders of a
majority of the shares of the Registrable Securities to be registered in such
Demand Registration. The Company may select any additional investment banks and
managers to be used in connection with the offering; provided that such
additional investment bankers and managers must be reasonably satisfactory to
the Holders of a majority of the shares of the Registrable Securities to be
registered in such Demand Registration. To the extent 10% or more of the
Registrable Securities so requested to be registered are excluded from the
offering in accordance with Section 2.4, the Holders of such Registrable
Securities shall have the right to one additional Demand Registration under this
Section in such twelve-month period with respect to such Registrable Securities.

            SECTION 2.3. Piggy-Back Registration. Subject to Section 2.1 hereof,
if the Company proposes to file a registration statement under the Securities
Act with respect to an underwritten equity offering by the Company for its own
account or for the account of any of its respective securityholders of any class
of security (other than (i) any registration statement filed by the Company
under the Securities Act relating to an offering of Common Stock for its own
account as a result of the exercise of the exchange rights set forth in Section
8.6 of the Partnership Agreement, (ii) any registration statement filed in
connection with a demand registration other than a Demand Registration under
this Agreement or (iii) a registration

                                       5
<PAGE>
statement on Form S-4 or S-8 (or any substitute form that may be adopted by the
Commission) or filed in connection with an exchange offer or offering of
securities solely to the Company's existing securityholders), then the Company
shall give written notice of such proposed filing to the Holders of Registrable
Securities as soon as practicable (but in no event less than ten (10) days
before the anticipated filing date), and such notice shall offer such Holders
the opportunity to register such number of shares of Registrable Securities as
each such Holder may request (a "Piggy-Back Registration"). The Company shall
use its commercially reasonable efforts to cause the managing Underwriter or
Underwriters of a proposed underwritten offering to permit the Registrable
Securities requested to be included in a Piggy-Back Registration to be included
on the same terms and conditions as any similar securities of the Company
included therein.

            SECTION 2.4. Reduction of Offering. Notwithstanding anything
contained herein, if the managing Underwriter or Underwriters of an offering
described in Section 2.2 or 2.3 deliver a written opinion to the Company and the
Holders of the Registrable Securities included in such offering that (i) the
size of the offering that the Holders, the Company and such other persons intend
to make or (ii) the kind of securities that the Holders, the Company and/or any
other Persons intend to include in such offering are such that the success of
the offering would be materially and adversely affected by inclusion of the
Registrable Securities requested to be included, then (A) if the size of the
offering is the basis of such Underwriter's opinion, the amount of securities to
be offered for the accounts of Holders shall be reduced pro rata (according to
the Registrable Securities proposed for registration) to the extent necessary to
reduce the total amount of securities to be included in such offering to the
amount recommended by such managing Underwriter or Underwriters; provided that,
in the case of a Piggy-Back Registration, if securities are being offered for
the account of other Persons as well as the Company, then with respect to the
Registrable Securities intended to be offered by Holders, the proportion by
which the amount of such class of securities intended to be offered by Holders
is reduced shall not exceed the proportion by which the amount of such class of
securities intended to be offered by such other Persons is reduced; and (B) if
the combination of securities to be offered is the basis of such Underwriter's
opinion, (x) the Registrable Securities to be included in such offering shall be
reduced as described in clause (A) above (subject to the proviso in clause (A))
or (y) if the actions described in clause (x) would, in the judgment of the
managing Underwriter, be insufficient to substantially eliminate the adverse
effect that inclusion of the Registrable Securities requested to be included
would have on such offering, such Registrable Securities will be excluded from
such offering.

            SECTION 2.5. Registration Procedures; Filings; Information. In
connection with any Shelf Registration Statement under Section 2.1 or whenever
Holders request that any Registrable Securities be registered pursuant to
Section 2.2 hereof, the Company will use its commercially reasonable efforts to
effect the registration and the sale of such Registrable Securities in
accordance with the intended method of disposition thereof as quickly as
practicable, and in connection with any such request:

                  (a) The Company will as expeditiously as possible prepare and
file with the Commission a registration statement on any form for which the
Company then qualifies or which counsel for the Company shall deem appropriate
and which form shall be available for the sale of the Registrable Securities to
be registered thereunder in accordance with the intended method of distribution
thereof, and use its commercially reasonable efforts to cause such filed

                                       6
<PAGE>
registration statement to become and remain effective for a period of not less
than 270 days; provided that if the Company shall furnish to the Holders making
a request pursuant to Section 2.2 a certificate signed by either its Chairman,
Vice Chairman, Chief Executive Officer or President stating that in his or her
good faith judgment it would be significantly disadvantageous to the Company or
its shareholders for such a registration statement to be filed as expeditiously
as possible, the Company shall have a period of not more than 180 days within
which to file such registration statement measured from the date of receipt of
the request in accordance with Section 2.2.

                  (b) The Company will, if requested, prior to filing a
registration statement or prospectus or any amendment or supplement thereto,
furnish to each Selling Holder and each Underwriter, if any, of the Registrable
Securities covered by such registration statement copies of such registration
statement as proposed to be filed, and thereafter furnish to such Selling Holder
and Underwriter, if any, such number of conformed copies of such registration
statement, each amendment and supplement thereto (in each case including all
exhibits thereto and documents incorporated by reference therein), the
prospectus included in such registration statement (including each preliminary
prospectus) and such other documents as such Selling Holder or Underwriter may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such Selling Holder.

                  (c) After the filing of the registration statement, the
Company will promptly notify each Selling Holder of Registrable Securities
covered by such registration statement of any stop order issued or threatened by
the Commission and take all reasonable actions required to prevent the entry of
such stop order or to remove it if entered.

                  (d) The Company will use its commercially reasonable efforts
to (i) register or qualify the Registrable Securities under such other
securities or blue sky laws of such jurisdictions in the United States (where an
exemption does not apply) as any Selling Holder or managing Underwriter or
Underwriters, if any, reasonably (in light of such Selling Holder's intended
plan of distribution) requests and (ii) cause such Registrable Securities to be
registered with or approved by such other governmental agencies or authorities
as may be necessary by virtue of the business and operations of the Company and
do any and all other acts and things that may be reasonably necessary or
advisable to enable such Selling Holder to consummate the disposition of the
Registrable Securities owned by such Selling Holder; provided that the Company
will not be required to (A) qualify generally to do business in any jurisdiction
where it would not otherwise be required to qualify but for this paragraph (d),
(B) subject itself to taxation in any such jurisdiction or (C) consent to
general service of process in any such jurisdiction.

                  (e) The Company will immediately notify each Selling Holder of
such Registrable Securities, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Securities,
such prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading and promptly make available to each Selling Holder any such
supplement or amendment.

                                       7
<PAGE>
                  (f) The Company will enter into customary agreements
(including an underwriting agreement, if any, in customary form) and take such
other actions as are reasonably required in order to expedite or facilitate the
disposition of such Registrable Securities.

                  (g) The Company will make available for inspection by any
Selling Holder of such Registrable Securities, any Underwriter participating in
any disposition pursuant to such registration statement and any attorney,
accountant or other professional retained by any such Selling Holder or
Underwriter (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise their due
diligence responsibility, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any Inspectors in
connection with such registration statement. Records which the Company
determines, in good faith, to be confidential and which it notifies the
Inspectors are confidential shall not be disclosed by the Inspectors unless (i)
the disclosure of such Records is necessary to avoid or correct a misstatement
or omission in such registration statement or (ii) the release of such Records
is ordered pursuant to a subpoena or other order from a court of competent
jurisdiction. Each Selling Holder of such Registrable Securities agrees that
information obtained by it as a result of such inspections shall be deemed
confidential and shall not be used by it as the basis for any market
transactions in the securities of the Company unless and until such is made
generally available to the public. Each Selling Holder of such Registrable
Securities further agrees that it will, upon learning that disclosure of such
Records is sought in a court of competent jurisdiction, give notice to the
Company and allow the Company, at its expense, to undertake appropriate action
to prevent disclosure of the Records deemed confidential.

                  (h) The Company will furnish to each Selling Holder and to
each Underwriter, if any, a signed counterpart, addressed to such Selling Holder
or Underwriter, of (i) an opinion or opinions of counsel to the Company and (ii)
if eligible under SAS 72, a comfort letter or comfort letters from the Company's
independent public accountants, each in customary form and covering such matters
of the type customarily covered by opinions or comfort letters, as the case may
be, as the Holders of a majority of the Registrable Securities included in such
offering or the managing Underwriter or Underwriters therefor reasonably
requests.

                  (i) The Company will otherwise comply with all applicable
rules and regulations of the Commission, and make available to its
securityholders, as soon as reasonably practicable, an earnings statement
covering a period of 12 months, beginning within three months after the
effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 of
the Commission promulgated thereunder (or any successor rule or regulation
hereafter adopted by the Commission).

                  (j) The Company will use its commercially reasonable efforts
to cause all such Registrable Securities to be listed on each securities
exchange on which similar securities issued by the Company are then listed.

                  The Company may require each Selling Holder of Registrable
Securities to promptly furnish in writing to the Company such information
regarding such selling Holder,

                                       8
<PAGE>
the Registrable Securities held by it and the intended method of distribution of
the Registrable Securities as the Company may from time to time reasonably
request and such other information as may be legally required in connection with
such registration.

                  Each Selling Holder agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
2.5(e) hereof, such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 2.5(e) hereof, and,
if so directed by the Company, such Selling Holder will deliver to the Company
all copies, other than permanent file copies then in such Selling Holder's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice. Each Selling Holder of Registrable
Securities agrees that it will immediately notify the Company at any time when a
prospectus relating to the registration of such Registrable Securities is
required to be delivered under the Securities Act of the happening of an event
as a result of which information previously furnished by such Selling Holder to
the Company in writing for inclusion in such prospectus contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances in which they were made. In the event the Company
shall give such notice, the Company shall extend the period during which such
registration statement shall be maintained effective (including the period
referred to in Section 2.5(a) hereof) by the number of days during the period
from and including the date of the giving of notice pursuant to Section 2.5(e)
hereof to the date when the Company shall make available to the Selling Holders
of Registrable Securities covered by such registration statement a prospectus
supplemented or amended to conform with the requirements of Section 2.5(e)
hereof.

            SECTION 2.6. Registration Expenses. In connection with any
registration statement required to be filed hereunder, the Company shall pay the
following registration expenses incurred in connection with the registration
hereunder (the "Registration Expenses"): (i) all registration and filing fees,
(ii) fees and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Registrable Securities), (iii) printing expenses, (iv)
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), (v) the fees
and expenses incurred in connection with the listing of the Registrable
Securities, (vi) reasonable fees and disbursements of counsel for the Company
and customary fees and expenses for independent certified public accountants
retained by the Company (including the expenses of any comfort letters or costs
associated with the delivery by independent certified public accountants of a
comfort letter or comfort letters requested pursuant to Section 2.5(h) hereof),
and (vii) the reasonable fees and expenses of any special experts retained by
the Company in connection with such registration. The Company shall have no
obligation to pay any underwriting fees, discounts or commissions attributable
to the sale of Registrable Securities, or any out-of-pocket expenses of the
Holders (or the agents who manage their accounts) or any transfer taxes relating
to the registration or sale of the Registrable Securities.

            SECTION 2.7. Indemnification by the Company. The Company agrees to
indemnify and hold harmless each Selling Holder of Registrable Securities, its
officers, directors

                                       9
<PAGE>
and agents, and each Person, if any, who controls such Selling Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
from and against any and all losses, claims, damages and liabilities caused by
any untrue statement or alleged untrue statement of a material fact contained in
any registration statement or prospectus relating to the Registrable Securities
(as amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) or any preliminary prospectus, or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
furnished in writing to the Company by such Selling Holder or on such Selling
Holder's behalf expressly for inclusion therein. The Company also agrees to
indemnify any Underwriters of the Registrable Securities, their officers and
directors and each Person who controls such underwriters within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act on
substantially the same basis as that of the indemnification of the Selling
Holders provided in this Section 2.7, provided that the foregoing indemnity with
respect to any preliminary prospectus shall not inure to the benefit of any
Underwriter of the Registrable Securities from whom the person asserting any
such losses, claims, damages or liabilities purchased the Registrable Securities
which are the subject thereof if such person did not receive a copy of the
prospectus (or the prospectus as supplemented) at or prior to the confirmation
of the sale of such Registrable Securities to such person in any case where such
delivery is required by the Securities Act and the untrue statement or omission
of a material fact contained in such preliminary prospectus was corrected in the
prospectus (or the prospectus as supplemented). The indemnity provided for in
this Section 2.7 shall remain in full force and effect regardless of any
investigation made by or on behalf of any Selling Holder.

            SECTION 2.8. Indemnification by Holders of Registrable Securities.
Each Selling Holder agrees, severally but not jointly, to indemnify and hold
harmless the Company, its officers, directors and agents and each Person, if
any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Selling Holder, but only with
respect to information relating to such Selling Holder furnished in writing by
such Selling Holder or on such Selling Holder's behalf expressly for use in any
registration statement or prospectus relating to the Registrable Securities, or
any amendment or supplement thereto, or any preliminary prospectus. In case any
action or proceeding shall be brought against the Company or its officers,
directors or agents or any such controlling person, in respect of which
indemnity may be sought against such Selling Holder, such Selling Holder shall
have the rights and duties given to the Company, and the Company or its
officers, directors or agents or such controlling person shall have the rights
and duties given to such Selling Holder, by Section 2.7. Each Selling Holder
also agrees to indemnify and hold harmless Underwriters of the Registrable
Securities, their officers and directors and each Person who controls such
Underwriters within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act on substantially the same basis as that of the
indemnification of the Company provided in this Section 2.8. The liability of
any Selling Holder pursuant to this Section 2.8 may, in no event, exceed the net
proceeds received by such Selling Holder from sales of Registrable Securities
giving rise to the indemnification obligations of such Selling Holder.

                                       10
<PAGE>
            SECTION 2.9. Conduct of Indemnification Proceedings. In case any
proceeding (including any governmental investigation) shall be instituted
involving any person in respect of which indemnity may be sought pursuant to
Section 2.7 or 2.8, such person (an "Indemnified Party") shall promptly notify
the person against whom such indemnity may be sought (an "Indemnifying Party")
in writing and the Indemnifying Party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Party, and shall assume the payment of all fees and expenses. In any such
proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the Indemnified Party and the Indemnifying Party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the Indemnifying Party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by (i) in the case
of Persons indemnified pursuant to Section 2.7 hereof, the Selling Holders which
owned a majority of the Registrable Securities sold under the applicable
registration statement and (ii) in the case of Persons indemnified pursuant to
Section 2.8, the Company. The Indemnifying Party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent, or if there be a final judgment for the plaintiff,
the Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Party shall have requested an Indemnifying Party
to reimburse the Indemnified Party for fees and expenses of counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
Business Days after receipt by such Indemnifying Party of the aforesaid request
and (ii) such Indemnifying Party shall not have reimbursed the Indemnified Party
in accordance with such request prior to the date of such settlement. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Party is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Party, unless such settlement
includes an unconditional release of such Indemnified Party from all liability
arising out of such proceeding.

            SECTION 2.10. Contribution. If the indemnification provided for in
Section 2.7 or 2.8 hereof is unavailable to an Indemnified Party or insufficient
in respect of any losses, claims, damages or liabilities referred to herein,
then each such Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party
as a result of such losses, claims, damages or liabilities (i) as between the
Company and the Selling Holders on the one hand and the Underwriters on the
other, in such proportion as is

                                       11
<PAGE>
appropriate to reflect the relative benefits received by the Company and the
Selling Holders on the one hand and the Underwriters on the other from the
offering of the securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and the Selling Holders on
the one hand and of the Underwriters on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations and (ii)
between the Company on the one hand and each Selling Holder on the other, in
such proportion as is appropriate to reflect the relative fault of the Company
and of each Selling Holder in connection with such statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Company
and the Selling Holders on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total proceeds from the offering
(net of underwriting discounts and commissions but before deducting expenses)
received by the Company and the Selling Holders bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the prospectus. The relative fault of
the Company and the Selling Holders on the one hand and of the Underwriters on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
and the Selling Holders or by the Underwriters. The relative fault of the
Company on the one hand and of each Selling Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

            The Company and the Selling Holders agree that it would not be just
and equitable if contribution pursuant to this Section 2.10 were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 2.10, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
commissions and discounts received by such Underwriter in connection with the
sale of the securities underwritten by it and distributed to the public exceeds
the amount of any damages which such Underwriter has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission, and no Selling Holder shall be required to contribute any amount in
excess of the amount by which the total price at which the securities of such
Selling Holder were offered to the public exceeds the amount of any damages
which such Selling Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Selling Holder's
obligations to contribute pursuant to this Section 2.10 are several in
proportion to the proceeds of the offering received by such Selling Holder bears
to the total proceeds of the offering received by all the Selling Holders and
not joint.

<PAGE>
            SECTION 2.11. Participation in Underwritten Registrations. No Person
may participate in any underwritten registration hereunder unless such Person
(a) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and these
registration rights provided for in this Article II.

            SECTION 2.12. Rule 144. The Company covenants that it will file any
reports required to be filed by it under the Securities Act and the Exchange Act
and that it will take such further action as any Holder may reasonably request,
all to the extent required from time to time to enable Holders to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act,
as such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Commission. Upon the request of any Holder,
the Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

            SECTION 2.13. Holdback Agreements.

                  (a) Restrictions on Public Sale by Holder of Registrable
Securities. To the extent not inconsistent with applicable law, each Holder
whose securities are included in a registration statement agrees not to effect
any sale or distribution of the issue being registered or a similar security of
the Company, or any securities convertible into or exchangeable or exercisable
for such securities, including a sale pursuant to Rule 144 under the Securities
Act, during the 14 days prior to, and during the 90-day period beginning on, the
effective date of such registration statement (except as part of such
registration), if and to the extent requested in writing by the Company in the
case of a non-underwritten public offering or if and to the extent requested in
writing by the managing underwriter or Underwriters in the case of an
underwritten public offering.

                  (b) Restrictions on Public Sale by the Company and Others. The
Company agrees that any agreement entered into after the date of this Agreement
pursuant to which the Company issues or agrees to issue any privately placed
securities shall contain a provision under which holders of such securities
agree not to effect any sale or distribution of any securities similar to those
being registered in accordance with Section 2.2 or Section 2.3 hereof, or any
securities convertible into or exchangeable or exercisable for such securities,
during the 14 days prior to, and during the 90-day period beginning on, the
effective date of any registration statement (except as part of such
registration statement where the Holders of a majority of the Registrable
Securities to be included in such registration statement consent or as part of
registration statements filed as set forth in Section 2.3(i) or (iii)), if and
to the extent requested in writing by the Company in the case of a
non-underwritten public offering or if and to the extent requested in writing by
the managing Underwriter or Underwriters in the case of an underwritten public
offering, in each case including a sale pursuant to Rule 144 under the
Securities Act (except as part of any such registration, if permitted);
provided, however, that the provisions of this paragraph (b) shall not prevent
the conversion or exchange of any securities pursuant to their terms into or for
other securities.

<PAGE>
                  (c) Temporary Suspension of Rights to Sell Based on
Confidential Information. If the Company determines in its good faith judgment
that the filing of the Shelf Registration Statement under Section 2.1 or a
Demand Registration under Section 2.2 hereof or the use of any related
prospectus would require the disclosure of material information that the Company
has a bona fide business purpose for preserving as confidential or the
disclosure of which would impede the Company's ability to consummate a
significant transaction, and that the Company is not otherwise required by
applicable securities laws or regulations to disclose, upon written notice of
such determination by the Company, the rights of the Holders to offer, sell or
distribute any Registrable Securities pursuant to the Shelf Registration
Statement or a Demand Registration or to require the Company to take action with
respect to the registration or sale of any Registrable Securities pursuant to
the Shelf Registration Statement or a Demand Registration shall be suspended
until the earlier of (i) the date upon which the Company notifies the Holders in
writing that suspension of such rights for the grounds set forth in this Section
2.12(c) is no longer necessary and (ii) 180 days. The Company agrees to give
such notice as promptly as practicable following the date that such suspension
of rights is no longer necessary.

                  (d) Temporary Suspension of Rights to Sell Based on Exchange
Act Reports not yet Filed or Regulation S-X. If all reports required to be filed
by the Company pursuant to the Exchange Act have not been filed by the required
date without regard to any extension, or if the consummation of any business
combination by the Company has occurred or is probable for purposes of Rule 3-05
or Article 11 of Regulation S-X under the Act, upon written notice thereof by
the Company to the Holders, the rights of the Holders to offer, sell or
distribute any Registrable Securities pursuant to the Shelf Registration
Statement or a Demand Registration or to require the Company to take action with
respect to the registration or sale of any Registrable Securities pursuant to
the Shelf Registration Statement or a Demand Registration shall be suspended
until the date on which the Company has filed such reports or obtained and filed
the financial information required by Rule 3-05 or Article 11 of Regulation S-X
to be included or incorporated by reference, as applicable, in the Shelf
Registration Statement, and the Company shall notify the Holders as promptly as
practicable when such suspension is no longer required.

                                   ARTICLE III
                                  MISCELLANEOUS

            SECTION 3.1. New York Stock Exchange Listing. In the event that the
Company shall issue any Common Stock in exchange for OP Units pursuant to
Section 8.6 of the Partnership Agreement, then in any such case the Company
agrees to cause any such shares of Common Stock to be listed on the New York
Stock Exchange prior to or concurrently with the issuance thereof by the
Company.

            SECTION 3.2. Remedies. In addition to being entitled to exercise all
rights provided herein and granted by law, including recovery of damages, the
Holders shall be entitled to specific performance of the rights under this
Agreement. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of this Agreement and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

                                       14
<PAGE>
            SECTION 3.3. Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, in each case without the written consent of
the Company and the Holders of a majority of the Registrable Securities. No
failure or delay by any party to insist upon the strict performance of any
covenant, duty, agreement or condition of this Agreement or to exercise any
right or remedy consequent upon any breach thereof shall constitute waiver of
any such breach or any other covenant, duty, agreement or condition.

            SECTION 3.4. Notices. All notices and other communications in
connection with this Agreement shall be made in writing by hand delivery,
registered first-class mail, telex, telecopier, or air courier guaranteeing
overnight delivery to the address set forth on the signature page hereto, or to
such other address and to such other Persons as any party hereto may hereafter
specify in writing.

            All such notices and communications shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; when
received if deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt acknowledged, if telecopied; and on the next
business day, if timely delivered to an air courier guaranteeing overnight
delivery.

            SECTION 3.5. Successors and Assigns. Except as expressly provided in
this Agreement the rights and obligations of the Initial Holders under this
Agreement shall not be assignable by any Initial Holder to any Person that is
