     This First Amendment to Amended and Restated Securities Purchase Agreement,

     WHEREAS, the Company and Silver Lake are parties to an Amended and Restated
Securities Purchase Agreement, dated as of August 29, 2000 (the "Securities
Purchase Agreement"), a Standstill Agreement, dated as of August 29, 2000 (the
"Standstill Agreement"), and a Registration Rights Agreement, dated as of August
29, 2000 (the "Registration Rights Agreement");

     WHEREAS, the Company, Silver Lake and the other Investors desire to amend
certain terms of the Securities Purchase Agreement, the Standstill Agreement and
the Registration Rights Agreement as set forth herein;

     NOW, THEREFORE, in consideration of the mutual promises hereinafter set
forth, the parties hereto hereby agree as follows:

1.  Definitions.  Capitalized terms used and not otherwise defined herein shall
    -----------
have the meanings set forth in the Securities Purchase Agreement.

2.  Amendment to Securities Purchase Agreement.
    ------------------------------------------

     2.1.  Amendment to Section 1.5(c) of Securities Purchase Agreement.
           ------------------------------------------------------------
Section 1.5(c) of the Securities Purchase Agreement is hereby amended and
restated in its entirety to read as follows:

     "(c)  The Replacement Warrants (i) will be immediately exercisable upon
     issuance (provided that they shall in any event become exercisable no later
     than immediately prior to the consummation of the triggering third-party
     acquisition, in the case of an event described in Section 1.5(a)(iii)
     above), and will remain exercisable until the later of (a) the fourth
     anniversary of the Closing or (b) the first anniversary of the consummation
     of the Purchase Right Flip-Up Event giving rise to the issuance of such
     Replacement Warrants, (ii) will have an initial aggregate exercise price
     equal to the product of (A) 5 2/3, multiplied by (B) the exercise price in
     effect for the related Callable Subsidiary Stock Purchase Rights
     immediately prior to such Purchase Right Flip-Up Event (subject to the
     following

<PAGE>

     proviso), (iii) will initially be exercisable for that percentage of the
     Company's diluted Common Stock equal to the product of (A) that percentage
     of the diluted common stock of the Operating Subsidiary for which the
     related Subsidiary Stock Purchase Rights were (or when issued, would have
     been) exercisable immediately prior to the consummation of such Purchase
     Right Flip-Up Event multiplied by (B) a fraction the numerator of which is
     the Flip-Up Valuation and the denominator of which is the market
     capitalization of the Company immediately preceding such Purchase Right
     Flip-Up Event, and (iv) otherwise will be on the terms and conditions set
     forth in the form of Parent Warrant; provided, however, that, in the case
                                          --------  -------
     of a Purchase Right Flip-Up Event described in clause (i) or clause (ii) of
     the definition thereof occurring prior to the second anniversary of the
     Closing, the initial aggregate exercise price of the Replacement Warrants
     shall be discounted, and shall equal the product of (A) 5 2/3, multiplied
     by (B) the exercise price in effect for the related Callable Subsidiary
     Stock Purchase Rights immediately prior to such Purchase Right Flip-Up
     Event, multiplied by (C) 0.9."

     2.2. Issuance of Subsidiary Warrants in Connection with Spin-Off. The
          -----------------------------------------------------------
Section acknowledge and agree that the Company intends to consummate a Spin-Off
of Riverstone (the "Riverstone Spin"). For the avoidance of doubt, the parties
further agree that the calculations set forth in the attached Exhibit A reflect
                                                              ---------
the proper application of Section 1.7 of the Securities Purchase Agreement in
connection with the Riverstone Spin, and, based on the assumptions set forth in
Exhibit A, (a) the exercise price per share of Common Stock under the Class A
---------
Parent Warrants and the Class B Parent Warrants outstanding on the date of the
Riverstone Spin would be adjusted as set forth in the attached Exhibit A, and
                                                               ---------
(b) the Company would cause Riverstone to issue to the Investors Subsidiary
Warrants with respect to the Class A Parent Warrants and Class B Parent Warrants
exercisable for the number of shares of common stock of Riverstone, and the
exercise price per share, set forth in the attached Exhibit A.  Subject to the
                                                    ---------
foregoing, such Subsidiary Warrants shall have such other terms as are described
in the Securities Purchase Agreement.

     2.3. Issuance of Replacement Warrants in Connection with Purchase Right
          ------------------------------------------------------------------
Flip-Up Event. The parties acknowledge and agree that the Company intends to
-------------
consummate a merger of Enterasys with and into the Company (the "Enterasys Flip-
Up Event") and that, in the event that the Riverstone Spin occurs within one
hundred and twenty days of the date hereof, the Riverstone Spin shall be deemed
to have occurred prior to the consummation of the Enterasys Flip-Up Event for
all purposes of the Securities Purchase Agreement and the issuance of
Replacement Warrants in connection with the Enterasys Flip-Up Event. The parties
further agree that, in the event that the Enterasys Flip-Up Event is consummated
within ninety days of the date hereof, pursuant to Section 1.5 of the Securities
Purchase Agreement (and notwithstanding anything in Section 1.5(c)(ii) or
1.5(c)(iii) to the contrary) in connection with the Enterasys Flip-Up Event, (a)
the Subsidiary Stock Purchase Rights issued to the Investors by Enterasys shall
be canceled, and (b) the Company shall issue to the Investors Replacement
Warrants exercisable for an aggregate of 7,400,000 shares of Common Stock, with
an aggregate exercise price of $45,880,000. Subject to the foregoing, such
Replacement Warrants shall have such other terms as are described in the
Securities Purchase Agreement.

     2.4. Further Notifications. The Company shall have no further obligation to
          ---------------------
provide the Investors with notice of the Riverstone Spin or the Enterasys Flip-
Up Event, provided that the Company consummates each of the foregoing upon the
          --------
terms and within the time periods contemplated by this Amendment and its
Exhibits.

     2.5.  References to the Company's Series A and Series B Participating
           ---------------------------------------------------------------
Convertible Preferred Stock.  Upon the consummation of the exchange by the
---------------------------
Company pursuant to a Securities Exchange Agreement among the parties hereto,

Convertible Preferred Stock for the outstanding shares of the Company's Series A

Securities Purchase Agreement (the "Exchange"), (a) the references in Sections

its entirety to read as follows:

          "(p)        "Preferred Stock" shall mean the Company's Series D and
     Series E Participating Convertible Preferred Stock, $1.00 par value per
     share."

4.  Amendment to Registration Rights Agreement.  Upon the consummation of the
    ------------------------------------------

                  CORNERSTONE NC OPERATING LIMITED PARTNERSHIP

     THIS AGREEMENT OF LIMITED PARTNERSHIP OF CORNERSTONE NC OPERATING LIMITED
PARTNERSHIP, dated as of September 30, 2001 (the "Effective Date"), is entered
into by and between Cornerstone Realty Income Trust, Inc., a Virginia
corporation, as the "General Partner", and State Street, LLC, a North Carolina
limited liability company and State Street I, LLC, a North Carolina limited
liability company, as the "Original Limited Partners".

                                   RECITALS
                                   --------

        WHEREAS, on September 30, 2001, the General Partner, entered into
Membership Interest Contribution Agreements (the "Contribution Agreements") with
the Original Limited Partners pursuant to which the Original Limited Partners
agreed to contribute to a partnership to be formed all of the membership
interests in seven lower-tiered limited liability companies holding real
property in North Carolina (the "Contributed Property").

        WHEREAS, the General Partner wishes to assign its rights and obligations
under the Contribution Agreements to the Partnership.

         NOW THEREFORE, in consideration of the foregoing recitals and covenants
between the parties contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                                   AGREEMENT
                                   ---------

                                   ARTICLE 1
                                 DEFINED TERMS
                                 -------------

     As used in this Agreement, except as otherwise expressly provided or unless
the context otherwise requires, (i) the terms defined in this Article include
the plural as well as the singular; (ii) all accounting terms not otherwise
defined herein have the meanings ascribed to them in accordance with GAAP;
(iii)all references in this Agreement to designated "Articles," "Sections" and
other subdivisions are to the designated Articles, Sections and other
subdivisions of this Agreement; (iv) the words "hereof" and "hereunder" and
other words of similar import refer to this Agreement as a whole and not to any
particular Article, Section or other subdivision; (v) "including" shall mean
"including, without limitation," "including, without limiting the generality of
the foregoing," and other phrases of similar import; and (v) the following terms
shall have the meanings ascribed to them set forth below.

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

     "Actions" has the meaning set forth in Section 7.7 hereof.

     "Additional Funds" has the meaning set forth in Section 4.2.A hereof.

                                       1

<PAGE>

     "Additional Limited Partner" means a Person admitted to the Partnership as
a Limited Partner pursuant to Section 4.2.D or 11.4 hereof and who is shown as
such on the books and records of the Partnership.

     "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:

          (a) decrease such deficit by any amounts that such Partner is
     obligated to restore pursuant to this Agreement or by operation of law upon
     liquidation of such Partner's Partnership Interest or is deemed to be
     obligated to restore pursuant to the penultimate sentence of each of
     Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5); and

          (b) increase such deficit 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.

     "Adjustment Factor" means 1.0; provided, however, that in the event that:

          (a) the General Partner (i) declares or pays a dividend on its
     outstanding REIT Shares in REIT Shares or makes a distribution to all
     holders of its outstanding REIT Shares in REIT Shares, (ii) splits or
     subdivides its outstanding REIT Shares or (iii) effects a reverse stock
     split or otherwise combines its outstanding REIT Shares into a smaller
     number of REIT Shares, the Adjustment Factor shall be adjusted by
     multiplying the Adjustment Factor previously in effect by a fraction, (1)
     the numerator of which shall be the number of REIT Shares issued and
     outstanding on the record date for such dividend, distribution, split,
     subdivision, reverse split or combination (assuming for such purposes that
     such dividend, distribution, split, subdivision, reverse split or
     combination has occurred as of such time) and (2) the denominator of which
     shall be the actual number of REIT Shares (determined without the above
     assumption) issued and outstanding on the record date for such dividend,
     distribution, split, subdivision, reverse split or combination;

          (b) in the event that the General Partner distributes any rights,
     options or warrants to all holders of its REIT Shares to subscribe for or
     to purchase or to otherwise acquire REIT Shares (or other securities or
     rights convertible into, exchangeable for or exercisable for REIT Shares)at
     a price per share less than the Value of a REIT Share on the record date
     for such distribution (each a "Distributed Right"), then the Adjustment
     Factor shall be adjusted by multiplying the Adjustment Factor previously in
     effect by a fraction, (i) the numerator of which shall be the number of
     REIT Shares issued and outstanding on the record date plus the maximum
     number of REIT Shares purchasable under such Distributed Rights and (ii)
     the denominator of which shall be the number of REIT Shares issued and
     outstanding on the record date plus a fraction, (1) the numerator of which
     is the maximum number of REIT Shares purchasable under such Distributed
     Rights times the minimum purchase price per REIT Share under such
     Distributed Rights and (2) the

                                       2

<PAGE>

     denominator of which is the Value of a REIT Share as of the record date;
     provided, however, that, if any such Distributed Rights expire or become no
     longer exercisable, then the Adjustment Factor shall be adjusted, effective
     retroactive to the date of distribution of the Distributed Rights, to
     reflect a reduced maximum number of REIT Shares or any change in the
     minimum purchase price for the purposes of the above fractions;

          (c) in the event that the General Partner shall, by dividend or
     otherwise, distribute to all holders of its REIT Shares evidences of its
     indebtedness or assets (including securities, but excluding any cash
     dividend or any dividend or distribution referred to in subsection (a)
     above), which evidences of indebtedness or assets relate to assets not
     received by the General Partner pursuant to a pro rata distribution by the
     Partnership, then the Adjustment Factor shall be adjusted to equal the
     amount determined by multiplying the Adjustment Factor in effect
     immediately prior to the close of business on the date fixed for
     determination of shareholders entitled to receive such distribution by a
     fraction, (i) the numerator shall be such Value of a REIT Share on the date
     fixed for such determination and (ii) the denominator shall be the Value of
     a REIT Share on the dated fixed for such determination less the then Fair
     Market Value (as reasonably determined by the General Partner) of the
     portion of the evidences of indebtedness or assets so distributed
     applicable to one REIT Share.

Any adjustments to the Adjustment Factor shall become effective immediately
after the effective date of such event, retroactive to the record date, if any,
for such event. For illustrative purposes, examples of adjustments to the
Adjustment Factor are set forth on Exhibit B attached hereto.

     "Affiliate" means, with respect to any Person, any Person directly or
indirectly controlling or controlled by or under common control with such
Person. For the purposes of this definition, "Control" when used with respect to
any Person means the possession, directly or indirectly, of the power to direct
or cause the direction of the management and policies of such Person, whether
through the ownership of voting securities, by contract or otherwise, and the
terms "Controlling" and "Controlled" have meanings correlative to the foregoing.

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

     "Applicable Percentage" has the meaning set forth in Section 8.6.B hereof.

     "Appraisal" means, with respect to real property or any interest therein
(other than the Real Property), the written 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 Fair Market Value for such asset as set by the
General Partner is fair, from a financial point of view, to the Partners and/or
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 an Additional Limited Partner or a Substituted Limited Partner, and who
has the rights set forth in Section 11.5 hereof.

                                       3

<PAGE>

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

          (a) the sum, without duplication, of:

               (1) the Partnership's Net Income or Net Loss (as the case may be)
          for such period;

     Section 4.2 Additional Funding And Capital Contributions

     A. General. The General Partner may, in good faith, at any time and from
time to time, determine that the Partnership requires additional funds
("Additional Funds") in order to meet its Debts and obligations and fulfill the
purposes set forth in Section 3.1 hereof. 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 4.2 or Section 4.3 hereof.

     B. Notice of Additional Funds Requirement. The General Partner shall give
written notice (the "Funding Notice") to the Limited Partners of the need for
Additional Funds and the anticipated source(s) thereof.

     C. Partner Loans. The General Partner may lend Additional Funds to the
Partnership (a "Partner Loan") on terms and conditions no less favorable to the
Partnership than would be available to the Partnership from any third party;
provided, however, that in no event shall the aggregate outstanding principal
balance of all Partner Loans made by the General Partner exceed Five Million
Dollars ($5,000,000) the ("Loan Limit"); and provided further, that each Limited
Partner may elect, by delivering written notice to the General Partner within
thirty (30) days of the delivery of the Funding Notice, to participate in the
Partner Loan in the same proportionate share as such Limited Partner's Units
bears to the aggregate Units of all Holders, including the General Partner,
participating in such Loan, or such other share as the General Partner and such
Holders shall agree. In the event the General Partner has not elected to lend
Additional Funds to the Partnership, the General Partner has failed to make the
additional Capital Contribution required by Section 4.2(D) hereof, and a Limited
Partner has made a good faith determination that the lack of Additional Funds
could cause the Partnership to default in its obligations to third parties,
including any holder of any Debt secured by a mortgage or deed of trust on the
Real Property, such Limited Partner may elect, by delivering written notice to
the General Partner and all other Limited Partners, to lend Additional Funds to
the Partnership as a Partner Loan on terms and conditions no less favorable to
the Partnership than would be available to the Partnership from any third party.
In such event, within thirty (30) days of the delivery of the foregoing notice,
each other Limited Partner may elect, by delivering written notice to the
notifying Limited Partner to participate in the Partner Loan in the same
proportionate share as such Limited Partner's Units bears to the aggregate Units
of all Holders participating in such Loan, or such other share as the notifying
Limited Partner and such Holders shall agree.

     D. Additional General Partner Contributions; Additional Limited Partners.
In the event the General Partner has failed to make a Partner Loan in the full
amount of the Additional Funds or in the event the General Partner has reached
the Loan Limit(and the Original Limited Partners have elected not to make
Partner Loans in an amount equal to the unfunded Additional Funds), the General
Partner shall make additional cash Capital Contributions in an amount equal to
such unfunded Additional Funds. Whether or not a Funding Notice is given to the
Limited Partners, the General Partner on behalf of the Partnership may raise all
or any portion of the Additional Funds by making additional Capital
Contributions and/or accepting additional Capital Contributions from any other
Partners and/or third parties and either (i) in the case of Partners (including
the General Partner),increasing such Partner's Partnership Units; or (ii) in the
case of a third party, admitting

                                      21

<PAGE>

such third party as an Additional Limited Partner; provided, however, that the
General Partner shall have secured the consent required under Section 12.2(A).
Subject to the terms of this Section 4.2 and to the definition of "Gross Asset
Value," the General Partner shall determine in good faith the amount, terms and
conditions of such additional Capital Contributions; provided, however, that (i)
in no event shall any such Contribution entitle the maker thereof to a
distribution or return prior to, the distribution and return to which the
Holders of Preferred Partnership Units are entitled hereunder; and (ii) in the
case of an additional Capital Contribution by the General Partner, the
Partnership shall issue to the General Partner the number of Partnership Units
derived by dividing (a) the amount of the additional Capital Contribution (net
of any liabilities assumed or taken subject to by the Partnership) by (b) the
Value determined as of the date of such Capital Contribution.

     Section 4.3 Loans By Third Parties

     The Partnership may incur or assume Debt, or enter into other similar
credit, guarantee, financing or refinancing arrangements, for any purpose, upon
such terms as the General Partner determines appropriate; subject, however, to
the limitations of Sections 7.3 and 7.4 hereof, the Partner Schedule attached
hereto as Exhibit A, and the proviso of Section 7.9(D) hereof.

     Section 4.4 No Interest; No Return

     No Partner shall be entitled to interest on its Capital Contribution or on
such Partner's Capital Account. Except as provided herein or by law, no Partner
shall have any right to demand or receive the return of its Capital Contribution
from the Partnership.

     number of Preferred Partnership Units held by such Holder as of the
     Partnership Record Date; and (ii) any accrued but unpaid amounts previously
     distributable to such Holder (or its predecessor) under clause (i), above,
     plus interest thereon at the Prime Rate in effect on the scheduled date of
     such distribution under such clause (i) for the period commencing with such
     scheduled date and ending on the date of its distribution hereunder;
     provided, however, that the amount distributable pursuant to clause (i) to
     any Additional Limited Partner holding Preferred Partnership Units admitted
     to the Partnership in the quarter immediately preceding and ending with
     such Partnership Record Date shall be prorated based on the number of days
     that such Additional

     Limited Partner was a Holder of such Preferred Partnership Units during

frequent basis and provide for an appropriate record date.

Partnership assets to the Holders and, in such event, subject to Section 8.8
hereof, such assets shall be distributed in such a fashion as to ensure that the
same are distributed and allocated in accordance with Articles 5, 6 and 10
hereof. In the event of a Terminating Capital Transaction, at the request of any
Original Limited Partner, the General Partner will use its best efforts to make
a distribution in kind of Partnership assets in accordance with the preceding
sentence.

     Section 5.3 Amounts Withheld

     All amounts withheld pursuant to the Code or any provisions of any state or
local tax law and Section 10.4 hereof with respect to any allocation, payment or
distribution to any Holder shall be treated as amounts paid or distributed to

Agreement.

     Notwithstanding the other provisions of this Article 5, net proceeds from a
Terminating Capital Transaction, and any other cash received or reductions in
reserves made after commencement of the liquidation of the Partnership, shall be

     Section 5.5 Restricted Distributions

     Notwithstanding any provision to the contrary contained in this Agreement,
neither the Partnership nor the General Partner, on behalf of the Partnership,
shall make a distribution to any Holder on account of its Partnership Interest
or interest in Partnership Units if such distribution would violate Section
50-73.100 of the Act or other applicable law.

<PAGE>

subject to Section 11.6.C hereof, an allocation to a Holder of a share of Net

Net Income or Net Loss.

     Section 6.2 General Allocations

     Except as otherwise provided in this Article 6 and subject to Section

     at the end of each Fiscal Year.

     Section 6.3 Additional Allocation Provisions

     Notwithstanding the foregoing provisions of this Article 6:

     A. Special Allocations. Gross income shall be allocated to each Holder of
Partnership Units for any Fiscal Year (and, if necessary, subsequent Fiscal
Years) to the extent that such Holder receives a distribution of the Preferred
Return Per Unit pursuant to Section 5.1.1 of this Agreement.

     B. Regulatory Allocations.

          (a) Minimum Gain Chargeback. Except as otherwise provided in
              -----------------------
     Regulations Section 1.704-2(f), notwithstanding the provisions of Section
     6.2 hereof, or any other provision of this Article 6, if there is a net
     decrease in Partnership Minimum Gain during any Fiscal 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.B(a) is intended to
     qualify as a "Minimum Gain Chargeback" within the meaning of Regulations
     Section 1.704-2(f) and shall be interpreted consistently therewith.

          (b) Partner Minimum Gain Chargeback. Except as otherwise provided in
              -------------------------------
     Regulations Section 1.704-2(i)(4) or in Section 6.3.B(a) hereof, if there
     is a net decrease in Partner Minimum Gain attributable to a Partner
     Nonrecourse Debt during any Fiscal 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

                                      24

<PAGE>

     respective amounts required to be allocated to each General Partner,
     Limited Partner and other 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.B(b) is intended to
     qualify as a "Chargeback Of Partner Nonrecourse Debt Minimum Gain" within
     the meaning of Regulations Section 1.704-2(i) and shall be interpreted
     consistently therewith.

          (c) Nonrecourse Deductions and Partner Nonrecourse Deductions. Any
              ---------------------------------------------------------
     Nonrecourse Deductions for any Fiscal Year shall be specially allocated to
     the Holders of Partnership Units in accordance with their share of Net Loss
     under Section 6.2. Any Partner Nonrecourse Deductions for any Fiscal 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
     Section 1.704-2(i).

          (d) 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 such Holder in an amount and manner sufficient to
     eliminate, to the extent required by such Regulations, the Adjusted Capital
     Account Deficit of such Holder as quickly as possible, provided that an
     allocation pursuant to this Section 6.3.B(d) 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.B(d) were not in the Agreement. It
     is intended that this Section 6.3.B(d) qualify and be construed as a
     "Qualified Income Offset" within the meaning of Regulations Section
     1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

          (e) Gross Income Allocation. In the event that any Holder has a
              -----------------------
     deficit Capital Account at the end of any Fiscal Year that is in excess of
     the sum of (i) the amount (if any) that such Holder is obligated to restore
     to the Partnership upon complete liquidation of such Holder's Partnership
     Interest and (ii) the amount that such Holder is deemed to be obligated to
     restore pursuant to 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
     eliminate such deficit as quickly as possible, provided that an allocation
     pursuant to this Section 6.3.B(e) 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.B(e) and Section 6.3.B(d) hereof
     were not in the Agreement.

          (f) Limitation on Allocation of Net Loss. To the extent that any
              ------------------------------------
     allocation of Net Loss would cause or increase an Adjusted Capital Account
     Deficit as to any Holder of Partnership Units, such allocation of Net Loss
     shall be reallocated among the other Holders of Partnership Units in
     accordance with their respective Partnership Units, subject to the
     limitations of this Section 6.3.B(f).

                                      25

<PAGE>

          (g) Section 754 Adjustment. To the extent that 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 of Partnership Units in complete liquidation of
     its 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 Partnership Units 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.

          (h) Curative Allocations. The allocations set forth in Sections
              --------------------
     6.3.B(a), (b), (c), (d), (e), (f) and (g) hereof (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 Section 6.1 hereof, 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 without violating the requirements giving rise to the Regulatory
     Allocations, 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.

     C. Allocation of Excess Nonrecourse Liabilities. 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 for a Fiscal Year
shall be as follows: one hundred percent (100%) to the Limited Partners and
Assignees (including the General Partner following the acquisition of Tendered
Units pursuant to Section 8.6 hereof) in accordance with their respective
Partnership Units at the end of such Fiscal Year.

     Section 6.4 Tax Allocations

     A. In General. Except as otherwise provided in this Section 6.4, for income
tax purposes under the Code and the Regulations each Partnership 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 hereof.

     B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding
Section 6.4.A hereof, Tax Items with respect to the Contributed Property or
other property that is contributed to the Partnership with a Gross Asset Value
that varies from its basis in the hands of the contributing Partner immediately
preceding the date of contribution shall be allocated among the Holders for
income tax purposes pursuant to Regulations promulgated under Code Section
704(c) so as to take into account such variation. The Partnership shall account
for such variation under the method set forth in the Partner Schedule attached
hereto as Exhibit A. In the event that the Gross Asset Value of any Partnership
asset is adjusted pursuant to

                                      26

<PAGE>

subsection (b) of the definition of "Gross Asset Value" (provided in Article 1
hereof), 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 Code Section 704(c) and
the applicable Regulations.

     Section 6.5 Other Provisions

     A. Other Allocations Upon Change in Law. In the event that the Code or any
Regulations require allocations of items of income, gain, loss, deduction or
credit different from those set forth in this Article 6, the General Partner is
hereby authorized to make new allocations in reliance on the Code and such
Regulations, such new allocations shall be effected pursuant to the fiduciary
duty of the General Partner to the Partnership and the other Partners; provided,
however, that in no event shall any such new allocations adversely affect the
net after-tax economic return to which the Limited Partners would otherwise be
entitled under this Agreement in the absence of such new allocations.

     B. Consistent Tax Reporting. The Partners acknowledge and are aware of the
income tax consequences of the allocations made by this Article 6 and hereby
agree to be bound by the provisions of this Article 6 in reporting their shares
of Net Income, Net Losses and other items of income, gain, loss, deduction and
credit for federal, state and local income tax purposes.

behalf of the Partnership without any further act, approval or vote of the
Partners.

<PAGE>

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 to the extent provided by applicable
law) in the Commonwealth of Virginia and the State of North Carolina and any

     exercising its rights under Section 8.6 hereof to effect a Redemption in

Partners, undertake, on behalf of the Partnership, any of the following actions
or enter into any transaction that would have the effect of any such action:

     any order, directive, opinion, ruling or regulation of a federal or state
     agency or contained in federal or state law; and

          (5) to reflect such changes as are reasonably necessary for the
     General Partner to maintain its status as a REIT or to satisfy the REIT
     Requirements.

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

     D. Notwithstanding any other provision hereof, this Agreement shall not be
amended, and no action may be taken by the General Partner, without the Consent
of each Limited Partner adversely affected, if such amendment or action would
(i) convert a Limited Partner Interest in the Partnership into a General Partner
Interest (except as a result of the General Partner acquiring such Partnership
Interest); (ii) modify the limited liability of a Limited Partner; (iii) alter
the rights of the Holders of Preferred Partnership Units to receive
distributions pursuant to Article 5 or Section 13.2.A hereof, including amending
or modifying any related definitions, or the allocations specified in Article 6
hereof; (iv) alter or modify the Redemption rights, Cash Amount or REIT Shares
Amount, or amend or modify any related definitions; or (v) amend this Section
7.3 or Section 7.4. Further, no amendment may alter the restrictions on the
General Partners authority set forth elsewhere in this Section 7.3 or Section
7.4 without the Consent specified therein. Any such amendment or action
consented to by any Limited Partner shall be effective as to that Limited
Partner, notwithstanding the absence of such Consent by any other Limited
Partner.

     Section 7.4 Refinancing, Sales

     The General Partner hereby represents and warrants to, and covenants with,
the Original Limited Partners that it will not breach or otherwise violate any
of its promises, agreements, undertaking or covenants set forth in the Partner
Schedule attached hereto as Exhibit A concerning, among other things, the
financing or refinancing of any Partnership Debt and the sale,

                                      31

exchange, or other disposition of any Real Property, except as expressly
permitted under Section 7.9(D) hereof.

     Section 7.5 [Reserved]

     Section 7.6 Other Business of the General Partner

     The General Partner may engage independently or with others in other
business ventures of every nature and description, including the ownership of
other properties and the making or management of other investments. Nothing in
this Agreement shall be deemed to prohibit the General Partner or any Affiliate
of the General Partner from dealing, or otherwise engaging in business with,
Persons transacting business with the Partnership, or from providing services
related to the purchase, sale, financing, management, development or operation
of real or personal property and receiving compensation therefor, and may have
business interests and engage in business activities in addition to those
relating to the Partnership, including business interests and activities that
are in direct or indirect competition with the Partnership or that may conflict
with or detract from the activities of the Partnership. Neither the Partnership
nor any Partner shall have any right by virtue of this Agreement or the
partnership relationship established hereby in or to such other ventures or
activities or to the income or proceeds derived therefrom, and the pursuit of
such ventures, even if competitive with the business of the Partnership, shall
not be deemed wrongful or improper and neither the General Partner or any
Affiliate of the General Partner shall have any obligation pursuant to this
Agreement to offer any interest in any such venture or activity to the
Partnership, any Limited Partner or any such Person, even if such opportunity is
of a character that, if presented to the Partnership, any Limited Partner or
such other Person, could be taken by such Person.

     Section 7.7 Indemnification

     A. To the fullest extent permitted by applicable law, the Partnership shall
indemnify each Indemnitee from and against any and all losses, claims, damages,
liabilities, joint or several, expenses (including attorney's fees and other
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 ("Actions") in which such Indemnitee
may be involved, or is threatened to be involved, as a party or otherwise;
provided, however, that the Partnership shall not indemnify an Indemnitee (i)
for willful misconduct, gross negligence or a knowing violation of the law; (ii)
for any transaction for which such Indemnitee received an improper personal
benefit in violation or breach of any provision of this Agreement; or (iii) for
liabilities incurred in violation of the terms of this Agreement; and provided
further, however, that the General Partner shall make every effort not to cause
the Partnership to sell any of its property to fund any such indemnity. The
foregoing indemnity shall extend to any liability of any Indemnitee, pursuant to
a loan guaranty or otherwise, for any indebtedness of the Partnership (including
any indebtedness which 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. It is the intention of this Section
7.7.A that the Partnership indemnify each Indemnitee to the

                                      32

<PAGE>

fullest extent permitted by law. The termination of any proceeding by judgment,
order or settlement does not create a presumption that the Indemnitee did not
meet the requisite standard of conduct set forth in this Section 7.7.A. Any
indemnification pursuant to this Section 7.7 shall be made first out of
Available Cash of the Partnership generated in the ordinary course of
Partnership operations, and neither the General Partner nor any Limited Partner
shall have any obligation to contribute to the capital of the Partnership or
otherwise provide funds to enable the Partnership to fund its obligations under
this Section 7.7.

     B. To the fullest extent permitted by applicable law, each Partner shall
indemnify each other Indemnitee from and against any and all Actions in which
such Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise attributable to such Partner's willful misconduct, gross negligence,
knowing violation of the law or transaction for which such Partner received an
improper personal benefit in violation or breach of any provision of this
Agreement.

     C.   To the fullest extent permitted by law, expenses incurred by an
Indemnitee who is a party to a proceeding or otherwise subject to or the focus
of or is involved in any Action shall be paid or reimbursed by the indemnifying
party as incurred by the Indemnitee in advance of the final disposition of the
Action upon receipt by the indemnifying party 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 indemnifying party under 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 such
standard of conduct has not been met.

     D. 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 and shall inure to the benefit of the heirs, successors, assigns
and administrators of the Indemnitee unless otherwise provided in a written
agreement with such Indemnitee or in the writing pursuant to which such
Indemnitee is indemnified.

     E. The Partnership may, but shall not be obligated to, purchase and
maintain insurance, on behalf of any 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.

     F. In no event may an Indemnitee subject any of the 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

                                      33

<PAGE>

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. It is the intent of the Partners that any amounts paid by the
Partnership to a Partner pursuant to this Section 7.7 shall be treated as
"Guaranteed Payments" within the meaning of Code Section 707(c).

     Section 7.8 Liability Of The General Partner

     A. Notwithstanding anything to the contrary set forth in this Agreement,
neither the General Partner nor any of its directors or officers shall be liable
or accountable in damages or otherwise to the Partnership, any Partners or any
Assignees for losses sustained, liabilities incurred or benefits not derived as
a result of errors in judgment or mistakes of fact or law or of any act or
omission if the General Partner or such director or officer acted in good faith
unless any such error, mistake, act or omission constitutes gross negligence,
fraud, willful misconduct, a knowing violation of law or a breach of this
Agreement.

     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 shareholders collectively and that the General Partner is under no
obligation to give priority to the separate interests of the Limited Partners or
the General Partner's shareholders in deciding whether to cause the Partnership
to take (or decline to take) any actions; provided, however, that the General
Partner shall at all times, in good faith, attempt to minimize any adverse tax
consequences to the Original Limited Partners as a result of such action or
inaction; and provided further, however, that no such action or inaction may
breach or otherwise violate any of the promises, agreements, undertakings or
covenants of the General Partner set forth in the Partner Schedule attached
hereto as Exhibit A.

     C. 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 employees or agents (subject to the supervision
and control of the General Partner).

     D. Any amendment, modification or repeal of this Section 7.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's, and its officers' and directors',
liability to the Partnership or 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.

     E. To the fullest extent permitted by law, no officer, director or
shareholder of the General Partner shall be liable to the Partnership for money
damages except for (a) active and deliberate dishonesty; or (b) actual receipt
of an improper benefit or profit in money, property or services. This Agreement
is executed by the officers of the General Partner solely as officers of the
same and not in their own individual capacities.

                                      34

<PAGE>

     F. To the extent that, at law or in equity, the General Partner has duties
(including fiduciary duties) and liabilities relating thereto to the Partnership
or the Limited Partners, the General Partner shall not be liable to the
Partnership or to any other Partner for its good faith reliance on the
provisions of this Agreement. The provisions of this Agreement, to the extent
that they restrict the duties and liabilities of the General Partner otherwise
existing at law or in equity, are agreed by the Partners to replace such other
duties and liabilities of such General Partner.

     G. Notwithstanding anything to the contrary set forth in this Agreement,
the General Partner acknowledges that the obligation of the Partnership to
redeem Tendered Units in accordance with Section 8.6.A hereof, and the
obligation of the General Partner to cause the Partnership to deliver the Cash
Amount for Tendered Units in accordance with Section 8.6.B hereof if the General
Partner has failed to exchange REIT Shares for Tendered Units in accordance with
the provisions thereof, are affirmative obligations of the General Partner on
behalf of the Partnership or on its own behalf, and no Tendering Party shall be
obligated to seek or exhaust its remedies against the Partnership prior to
seeking the Cash Amount directly from the General Partner.

     Section 7.9 Other Matters Concerning The General Partner

     A. Except as otherwise provided to the contrary herein, the General Partner
shall at all times act in its fiduciary capacity as a general partner of a
limited partnership.

     B. 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 in good faith to be genuine and to have been signed
or presented by the proper party or parties.

     C. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers, architects, engineers,
environmental consultants 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 that the 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.

     D. Notwithstanding any other provisions of this Agreement or the Act, any
action of the General Partner on behalf of the Partnership or any decision of
the General Partner to refrain from acting on behalf of the Partnership,
undertaken in the good faith belief that such action or omission is necessary or
advisable in order (i) to protect the ability of the General Partner to continue
to qualify as a REIT, (ii) for the General Partner otherwise to satisfy the REIT
Requirements or (iii) to avoid the General Partner incurring any taxes under
Code Section 857 or Code Section 4981, is expressly authorized under this
Agreement and is deemed approved by all of the Limited Partners. The General
Partner will attempt to minimize the recognition of any taxable income or gain
by the Original Limited Partners resulting from such action or omission.

     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 Partner, individually or collectively with other Partners or
Persons, shall have any ownership interest in such Partnership assets or any
portion thereof.

                                    ARTICLE 8
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS
                   ------------------------------------------

     Section 8.1 Limitation Of Liability

     Except for the capital contributed by the Original Limited Partners
pursuant to Section 4.1 hereof, the Original Limited Partners shall have no
further obligation to fund any amounts to the Partnership. The Limited Partners
shall have no liability under this Agreement except as expressly provided in
this Agreement or under the Act.

     Section 8.2 Management Of Business

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

     Section 8.3 Outside Activities Of A Limited Partner

     A Limited Partner may engage independently or with others in other business
ventures of every nature and description, including the ownership of other
properties and the making or management of other investments. Nothing in this
Agreement shall be deemed to prohibit a Limited Partner or any Affiliate of a
Limited Partner from dealing, or otherwise engaging in business with, Persons
transacting business with the Partnership, or from providing services related to
the purchase, sale, financing, management, development or operation of real or
personal property and receiving compensation therefor, and may have business
interests and engage in business activities in addition to those relating to the
Partnership, including business interests and activities that are in direct or
indirect competition with the Partnership or that may conflict with or detract
from the activities of the Partnership. Neither the Partnership nor any Partner
shall have any right by virtue of this Agreement or the partnership relationship
established hereby in or to such other ventures or activities or to the income
or proceeds derived therefrom, and the pursuit of such ventures, even if
competitive with the business of the Partnership, shall not be deemed wrongful
or improper and neither a Limited Partner or any Affiliate of a Limited Partner
shall have any obligation pursuant to this Agreement to offer any interest in
any such venture or activity to the Partnership, the General

                                      36

<PAGE>

Partner, any other Limited Partner or any such Person, even if such opportunity
is of a character that, if presented to the Partnership, the General Partner,
any other 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
hereof, no Limited Partner shall be entitled to the withdrawal or return of its
Capital Contribution, except to the extent of distributions made pursuant to
this Agreement or upon termination of the Partnership as provided herein.
Except to the extent provided in  Sections 5.1 and 13.2 hereof or otherwise
expressly provided in this Agreement, 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 to profits, losses or distributions.

     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 hereof, each Limited Partner shall have
the right, upon written demand and at such Limited Partner's own expense:

          (1) to obtain a copy of (i) the most recent annual and quarterly
     reports filed with the SEC by the General Partner pursuant to the Exchange
     Act and (ii) each report or other written communication sent to the
     shareholders of the General Partner;

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

          (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
     pursuant to which this Agreement, the Certificate and all amendments
     thereto have been executed; and

          (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 that each Partner has agreed to contribute
     in the future, and the date on which each became a Partner.

     B. On written request, the Partnership shall notify any Limited Partner
that is a Qualifying Party of the then current Adjustment Factor or any change
made to the Adjustment Factor or to the REIT Shares Amount applicable to such
Limited Partner.

     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

confidential.

                                      37

     Section 8.6 Redemption Rights Of Qualifying Parties

     A. At any time following the first anniversary of the Effective Date, a
Qualifying Party, but no other Limited Partner or Assignee (the "Tendering
Party"), shall have the right (subject to the terms and conditions set forth
herein) to require the Partnership to redeem all or a portion of the Preferred
Partnership Units held by such Tendering Party (such Preferred Partnership Units
being hereafter called "Tendered Units") in exchange (a "Redemption") for the
Cash Amount, which Cash Amount shall be due and payable on the Cut-Off Date,
unless the General Partner makes an election pursuant to Section 8.6.B hereof.
Any Redemption shall be exercised pursuant to a Notice of Redemption delivered
to the General Partner by the Qualifying Party when exercising the Redemption
right. In the event of a Redemption, the Cash Amount shall be delivered in
exchange for the Tendered Units by a certified check payable to the Tendering
Party or otherwise in immediately available funds. In the event the payment of
such Cash Amount by the Partnership would impair of otherwise adversely affect
the amount of Available Cash required to satisfy, on a current basis, the
distribution priority to the Holders of Preferred Partnership Units, the General
Partner shall make a cash Capital Contribution to the Partnership in the amount
of such Cash Amount.

     B. Notwithstanding the provisions of Section 8.6.A hereof, on or before the
close of business on the Cut-Off Date, the General Partner may, in its sole and
absolute discretion but subject to the Ownership Limit, acquire some or all
(such percentage being referred to as the "Applicable Percentage") of the
Tendered Units from the Tendering Party in exchange for REIT Shares instead of
the Cash Amount. If the General Partner so elects, on the Redemption Date the
Tendering Party shall sell such number of the Tendered Units to the General
Partner in exchange for a number of REIT Shares equal to the product of the REIT
Shares Amount and the Applicable Percentage; provided, however, that in lieu of
any fractional REIT Share resulting from such calculation, the General Partner
may tender the Cash Amount attributable to such fractional REIT Share. The
Tendering Party shall submit (i) such information, certification or affidavit as
the General Partner may reasonably require in connection with the application of
the Ownership Limit and other restrictions and limitations of the Charter to any
such acquisition and (ii) such written representations, investment letters
(except in the case of the Original Partner), legal opinions or other
instruments necessary, in the General Partner's good faith opinion, to effect
compliance with the Securities Act. The REIT Shares shall be delivered by the
General Partner as duly authorized, validly issued, fully paid and
nonassessable, fully registered and, in the case of the Original Limited
Partner, freely saleable REIT Shares free of any pledge, lien, encumbrance or
restriction, other than the Ownership Limit and, if applicable, the Rights shall
be delivered free of any pledge, lien, encumbrance or restriction other than the
Ownership Limit and the Securities Act and relevant state securities or "Blue
Sky" laws. In the event that either (i) the General Partner has not or cannot
deliver the REIT Shares and, if applicable, the Rights, subject in each instance
only to the foregoing restrictions, on or before the Redemption Date; or (ii)
the Tendering Party is unable to satisfy the requirements of clauses (i) or
(ii), above, the General Partner shall cause the Partnership to deliver to the
Tendering Party, in lieu thereof, the Cash Amount in accordance with the
provisions of Section 8.6.A hereof. The General Partner shall be entitled to
suspend the use of any registration statement under the Securities Act covering
the REIT Shares for a reasonable period of time, but not to exceed 90 days
aggregate (a "Delay Period"), if any executive officer of the General Partner
determines that in such executive officer's reasonable good faith

                                      38

<PAGE>

judgment the registration and distribution of the REIT Shares covered by such
registration statement would materially interfere with any pending material
financing, acquisition or corporate reorganization or other material corporate
development involving the General Partner or any of its subsidiaries or would
require premature disclosure thereof and promptly gives the Qualifying Party
written notice of such determination, containing a general statement of the
reasons for such deferral and an approximation of the period of the anticipated
delay (provided that nothing herein shall require the General Partner to
disclose any terms of any such transaction or the identity of any party
thereto); provided, however the aggregate number of days included in all Delay
Periods shall not exceed 180 days. Immediately upon receipt of a written notice
of suspension, each Qualifying Party shall cease all disposition efforts with
respect to REIT Shares held by such Qualifying Party.

     C. Notwithstanding the provisions of Section 8.6.B hereof, the General
Partner shall not, under any circumstances, elect to acquire Tendered Units in
exchange for the REIT Shares Amount if such exchange would be prohibited under
the Charter.

     D. Notwithstanding anything herein to the contrary, with respect to any
Redemption or acquisition of Tendered Units pursuant to Section 8.6.B hereof:

          (1) All Partnership Units acquired by the General Partner pursuant to
     Section 8.6.B hereof shall automatically, and without further action
     required, be converted into and deemed to be General Partner Interests
     comprised of the same number of Partnership Units.

          (2) No Tendering Party, where the Redemption would consist of less
     than all the Partnership Units held by Partners other than the General
     Partner, shall be entitled to elect or effect a Redemption to the extent
     that the aggregate Partnership Units of the Limited Partners would be
     reduced, as a result of the Redemption (or the acquisition of the Tendered
     Units by the General Partner pursuant to Section 8.6.B hereof), to less
     than one percent (1%) of all Partnership Units outstanding immediately
     prior to delivery of the Notice of Redemption.

          (3) Subject to the Ownership Limit, no Tendering Party may effect a
     Redemption of less than twenty-five percent of its Partnership Units or, if
     such Tendering Party holds (as a Limited Partner or, economically, as an
     Assignee) less than five hundred (500) Partnership Units, all of the
     Partnership Units held by such Tendering Party.

          (4) The consummation of such Redemption (or an acquisition of Tendered
     Units by the General Partner pursuant to Section 8.6.B hereof, as the case
     may be) 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.

          (5) The Tendering Party shall continue to own (subject, in the case of
     an Assignee, to the provisions of Section 11.5 hereof) all Partnership
     Units subject to any Redemption, and be treated as a Limited Partner or an
     Assignee, as applicable, with respect such Partnership Units for all
     purposes of this Agreement, until such Partnership Units are either paid
     for by the Partnership pursuant to Section 8.6.A hereof or transferred to
     the General Partner and paid

                                      39

<PAGE>

     for, by the issuance of the REIT Shares, pursuant to Section 8.6.B hereof
     on the Redemption Date. Until a Redemption Date and an acquisition of the
     Tendered Units by the General Partner pursuant to Section 8.6.B hereof, the
     Tendering Party shall have no rights as a shareholder of the General
     Partner with respect to the REIT Shares issuable in connection with such
     acquisition.

For purposes of determining compliance with the restrictions set forth in this
Section 8.6.D, all Partnership Units beneficially owned by a Related Party of a
Tendering Party shall be considered to be owned or held by such Tendering Party.

     E. In connection with an exercise of Redemption rights pursuant to this
Section 8.6, the Tendering Party shall submit the following to the General
Partner, in addition to the Notice of Redemption:

          (1) A written affidavit, dated the same date as, and accompanying, the
     Notice of Redemption, (a) disclosing the actual and constructive ownership,
     as determined for purposes of Code Sections 856(a)(6), 856(h), 856(d)(2)(B)
     and 856(d)(5), of REIT Shares by (i) such Tendering Party and (ii) any
     Related Party and (b) representing that, after giving effect to the
     Redemption or an acquisition of the Tendered Units by the General Partner
     pursuant to Section 8.6.B hereof, neither the Tendering Party nor any
     Related Party will own REIT Shares in excess of the Ownership Limit;

          (2) A written representation that neither the Tendering Party nor any
     Related Party has any intention to acquire any additional REIT Shares prior
     to the closing of the Redemption or an acquisition of the Tendered Units by
     the General Partner pursuant to Section 8.6.B hereof on the Redemption
     Date; and

          (3) An undertaking to certify, at and as a condition to the closing of
     (i) the Redemption or (ii) the acquisition of the Tendered Units by the
     General Partner pursuant to Section 8.6.B hereof on the Redemption Date,
     that either (a) the actual and constructive ownership of REIT Shares by the
     Tendering Party and any Related Party remain unchanged from that disclosed
     in the affidavit required by Section 8.6.E(1); or (b) after giving effect
     to the Redemption or an acquisition of the Tendered Units by the General
     Partner pursuant to Section 8.6.B hereof, neither the Tendering Party nor
     any Related Party shall own REIT Shares in violation of the Ownership
     Limit.

     F. Notwithstanding any other provision of this Agreement, a Limited Partner
or Assignee shall not be entitled to effect an exchange for REIT Shares to the
extent the ownership or right to acquire REIT Shares pursuant to such exchange
by such Partner or Assignee would cause such Partner or any other Person to
violate the Ownership Limit. To the extent any attempted exchange would be in
violation of this Section 8.6.F, it shall be null and void ab initio and such
Limited Partner or Assignee shall not require any rights or economic interests
in REIT Shares otherwise issuable upon such exchange.

     Section 8.7 Partnership Right To Call Limited Partner Interests

     Notwithstanding any other provision of this Agreement, on and after the

                                      40

<PAGE>

date on which the aggregate Partnership Units of the Limited Partners are less
than ten thousand (10,000), the Partnership shall have the right, but not the
obligation, from time to time and at any time to redeem any and all outstanding
Limited Partner Interests by treating any Limited Partner as a Tendering Party
who has delivered a Notice of Redemption pursuant to Section 8.6 hereof for the
amount of Partnership Units to be specified by the General Partner, in its sole
and absolute discretion, by notice to such Limited Partner that the Partnership
has elected to exercise its rights under this Section 8.7. Such notice given by
the General Partner to a Limited Partner pursuant to this Section 8.7 shall be
treated as if it were a Notice of Redemption delivered to the General Partner by
such Limited Partner. For purposes of this Section 8.7, (a) any Limited Partner
(whether or not otherwise a Qualifying Party) may, in the General Partner's sole
and absolute discretion, be treated as a Qualifying Party that is a Tendering
Party; and (b) the provisions of Sections 8.6.D(2) through 8.6.D(4) hereof shall
not apply.

     Section 8.8 Other Redemptions

     Nothing in this Agreement shall preclude the redemption of a Limited
Partner Interest or Partnership Units by the Partnership upon such terms and
conditions as may be negotiated between the Limited Partner or Assignee holding
such Limited Partner Interest or Partnership Units, on the one hand, and the
General Partner, on the other hand, in their sole and absolute discretion;
provided, however, in no event may any such redemption impair or otherwise
affect (i) the amount of Available Cash required to satisfy, on a current basis,
the distribution priority to the Holders of Preferred Partnership Units; or (ii)
the rights of the Tendering Parties to effect a Redemption or the ability of the
Partnership to perform its obligations under Section 8.6.A. Such a redemption
may include the payment of cash by the Partnership to the Limited Partner or
Assignee, in a lump sum or in installments, or the distribution in kind of
Partnership assets to such Limited Partner or Assignee (which assets may be
encumbered), including assets to be designated by the Limited Partner or
Assignee and acquired (with or without debt financing) by the Partnership. In
effecting any such redemption by negotiated agreement, none of the Partnership,
the General Partner, the Limited Partner and the Assignee, as the case may be,
shall have any duty to offer the same or similar terms for redemption of any
other Limited Partner Interest or Partnership Units.

     Section 8.9 Exchange Rights of Holders of Non-Preferred Partnership Units

     At the times specified in Exhibit D the Partnership shall exchange the
Non-Preferred Partnership Units specified in Exhibit D held by a Qualifying
Party (the "Non-Preferred Tendering Party") in exchange for Preferred
Partnership Units (the "Exchange"). The Non-Preferred Tendering Party shall
continue to own (subject, in the case of an Assignee, to the provisions of
section 11.5 hereof) all Preferred Partnership Units received in the Exchange
and be treated as a Limited Partner or an Assignee, as applicable, with respect
to such Partnership Units for all purposes of this Agreement. Until the
Exchange, the Non-Preferred Tendering Party shall have no rights as a Preferred
Partnership Unit Holder and no rights to distributions under Article 5 hereof or
allocations under Article 6 hereof.

respect to the Partnership's business, including all books and records necessary
to provide to the Limited Partners any information, lists and copies of

device, provided that the records so maintained are convertible into clearly
legible written form within a reasonable period of time.

during normal business hours of the General Partner, to inspect and copy, or to

reporting purposes, on an accrual basis in accordance with GAAP, or on such
other basis as the General Partner determines to be necessary or appropriate.

to be mailed to each Limited Partner of record as of the close of the Fiscal
Year an annual report containing financial statements of the Partnership for
such Fiscal Year, presented in accordance with GAAP. Such statements of the
Partnership need not be audited but, if not audited, shall be accompanied by a

the same were or will be used in connection with the audited financial
statements of the General Partner for the period covered thereby.

     B. As soon as practicable, but in no event later than one hundred five
(105) days after the close of each calendar quarter (except the last calendar

Limited Partner of record as of the last day of the calendar quarter a report
containing unaudited financial statements of the Partnership and such other
information as may be required by applicable law or regulation or as the General
Partner determines to be appropriate.

     Section 10.1 Preparation Of Tax Returns

     The General Partner shall arrange for the preparation and timely filing of
all returns with respect to Partnership income, gains, deductions, losses and
other items required of the Partnership for federal and state income tax
purposes and shall use all reasonable efforts to furnish, within ninety (90)
days of the close of each taxable year, the tax information reasonably required
by Limited Partners for federal and state income tax reporting purposes. The
Limited Partners shall promptly provide the General Partner with such
information relating to the Contributed Property, including tax basis and other
relevant information, as may be reasonably requested by the General Partner from
time to time.

     Section 10.2 Tax Elections

     Except as otherwise provided herein, the General Partner shall, in its sole
and absolute discretion, determine whether to make or revoke any available
election pursuant to the Code. Notwithstanding the preceding sentence, the
General Partner shall elect to use, on behalf of the Partnership, (i) if
requested by a Limited Partner or Assignee within thirty (30) days of the end of
a taxable year, the optional adjustment to basis of property of the Partnership
as provided by and in accordance with Code Section 754 and (ii) the "Recurring
Item" method of accounting provided under Code Section 461(h) with respect to
property taxes imposed on the Partnership's Properties.

     Section 10.3 Tax Matters Partner

     A. The General Partner shall be the "Tax Matters Partner" of the
Partnership for federal income tax purposes. 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 and expenses) shall be borne by the Partnership in
addition to any reimbursement pursuant to Section 7.5 hereof. 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.

     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 Code Section 6231) or a
     member of a "Notice Group" (as defined in Code Section 6223(b)(2));

                                      43

<PAGE>

          (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 United States
     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 that is attributable to any item required to be taken
     into account by a Partner for tax purposes, or an item affected by such
     item, each Original Limited Partner affected by such extension must consent
     to such extension, which consent will not unreasonably be withheld; and

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

The taking of any action and the incurring of any expense by the tax matters
partner in connection with any such proceeding, except to the extent required by
law, is a matter within the discretion of the tax matters partner and the
provisions relating to indemnification of the General Partner set forth in
Section 7.7 hereof shall be fully applicable to the tax matters partner in its
capacity as such. The General Partner will inform the Original Limited Partners
of any actions to be taken (and seek to obtain the input of the Original Limited
Partners) or taken by it pursuant to this Section 10.3

     Section 10.4 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 any taxes required to be withheld or paid by the Partnership pursuant
to Code Section 1441, Code Section 1442, Code Section 1445 or Code Section 1446.
Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a loan by the Partnership to such Limited Partner, which loan shall
be repaid by such Limited Partner within fifteen (15) days after notice from the
General Partner that such payment must be made unless (i) the Partnership
withholds such payment from a distribution that would otherwise be made to the
Limited Partner or (ii) the General Partner reasonably determines that such
payment may be satisfied out of the Available Funds of the Partnership that
would, but for such payment, be distributed to the Limited Partner. Each Limited
Partner hereby

                                      44

<PAGE>

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 10.4. In the event that a Limited Partner fails to pay any amounts
owed to the Partnership pursuant to this Section 10.4 when due, the General
Partner may, in its sole and absolute discretion, elect to make the payment to
the Partnership on behalf of such defaulting Limited Partner, and in such event
shall be deemed to have loaned such amount to such defaulting Limited Partner
and shall succeed to all rights and remedies of the Partnership as against such
defaulting Limited Partner (including the right to receive distributions). Any
amounts payable by a Limited Partner hereunder shall bear interest at the Prime
Rate plus four (4) percentage points (but not higher than the maximum lawful
rate) from the date such amount is due (I.E., fifteen (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.

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

     Section 11.1 Transfer

     A. No part of the interest of a Partner shall be subject to the claims of
any creditor and may not be voluntarily or involuntarily alienated or encumbered
except as may be specifically provided for in this Agreement.

     B. No Partnership Interest shall be Transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article 11.
Any Transfer or purported Transfer of a Partnership Interest not made in
accordance with this Article 11 shall be null and void ab initio.

     Section 11.2 Transfer Of General Partner's Partnership Interest

     A. The General Partner may not Transfer any of its General Partner Interest
or withdraw from the Partnership except as provided in Section 11.2.B hereof.

     B. The General Partner shall not withdraw from the Partnership and shall
not Transfer all or any portion of its interest in the Partnership other than to
an Affiliate of the General Partner without the Consent of the Limited Partners,
which Consent may be given or withheld in the sole and absolute discretion of
the Limited Partners; provided, however, that no such Consent shall be required
in the event of a Transfer or constructive Transfer to a successor to all or
substantially all of the assets of the General Partner or to a successor by
operation of law or otherwise in connection with the merger or consolidation of
the General Partner. Upon any Transfer or constructive Transfer of such a
Partnership Interest pursuant to the Consent of the Limited Partners or
otherwise in accordance with the provisions of this Section 11.2.B, the
transferee shall become a successor 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 (except that upon a Transfer to an Affiliate of the General
Partner, the General Partner shall remain 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

                                      45

<PAGE>

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 such Transfer shall, except for a Transfer to an Affiliate of the
General Partner, relieve the transferor General Partner of its obligations under
this Agreement without the Consent of the Limited Partners. In the event that
the General Partner withdraws from the Partnership, in violation of this
Agreement or otherwise, or otherwise dissolves or terminates, or upon the
bankruptcy of the General Partner, a Majority In Interest of the Limited
Partners may elect to continue the Partnership business by selecting a successor
General Partner in accordance with the Act.

     Section 11.3 Limited Partners' Rights To Transfer

     A. General. No Limited Partner other than the Original Limited Partners
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 the
sole and absolute discretion of the General Partner; provided, however, that a
Limited Partner other than the Original Limited Partners may (i) at any time,
without the consent of the General Partner, Transfer all or part of its
Partnership Interest to a Qualified Transferee who is also (A) a Family Member
of such Limited Partner; (B) a trust, whether or not revocable, of which such
Limited Partner or such Limited Partner's Family Members are the sole
beneficiaries; (C) an organization described in Code Section 501(c)(3); or (D)
an Affiliate; or (ii) pledge all or any portion of its Partnership Interest to a
lending institution that 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 of credit.
The Original Limited Partners may transfer all or any portion of their
Partnership Interest without the consent of the General Partner or any other
Limited Partner. Any Transfer permitted by this proviso is hereinafter referred
to as a "Permitted Transfer". It is a condition to any Transfer otherwise
permitted hereunder (whether or not such Transfer is a Permitted Transfer) that
the transferee assume 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. Notwithstanding the foregoing, any
transferee of any Transferred Partnership Interest shall be subject to any and
all ownership limitations (including the Ownership Limit) contained in the
Charter that may limit or restrict such transferee's ability to exercise its
Redemption rights, including the Ownership Limit. Any transferee, whether or not
admitted as an Additional Limited Partner or a Substituted Limited Partner,
shall take subject to the obligations of the transferor hereunder. Unless
admitted as an Additional Limited Partner or 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 hereof.

     B. Incapacity. If a Limited Partner is subject to Incapacity, the executor,
administrator, trustee, committee, guardian, conservator or receiver of such
Limited Partner's estate shall have all the rights of a Limited Partner, but not
more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate, and such power

                                      46

<PAGE>

as the Incapacitated Limited Partner possessed to Transfer all or any part of
its interest in the Partnership. The Incapacity of a Limited Partner, in and of
itself, shall not dissolve or terminate the Partnership.

     C. Opinion of Counsel. In connection with any Transfer of a Limited Partner
Interest, the General Partner shall have the right to receive an opinion of
counsel satisfactory to it to the effect that the proposed Transfer may be
effected without registration under the Securities Act and will not otherwise
violate any federal or state securities laws or regulations applicable to the
Partnership or the Partnership Interests Transferred. If, in the opinion of such
counsel, such Transfer would require the filing of a registration statement
under the Securities Act or would otherwise violate any federal or state
securities laws or regulations applicable to the Partnership or the Partnership
Units, the General Partner may prohibit any Transfer otherwise permitted under
this Section 11.3 by a Limited Partner of Partnership Interests.

     D. Adverse Tax Consequences. No Transfer by a Limited Partner of its
Partnership Interests (including any Redemption, any other acquisition of
Partnership Units by the General Partner or any acquisition of Partnership Units
by the Partnership) may be made to any person if (i) in the opinion of legal
counsel for the Partnership, it would result in the Partnership being treated as
an association taxable as a corporation; or (ii) such Transfer is effectuated
through an "Established Securities Market" or a "Secondary Market (or the
substantial equivalent thereof)" within the meaning of Code Section 7704.

     Section 11.4 Additional Or Substituted Limited Partners

     A. No Limited Partner other than the Original Limited Partners shall have
the right to substitute a transferee (including any transferee pursuant to
Transfers permitted by Section 11.3 hereof) as a Limited Partner in its place. A
transferee of the entire interest of a Limited Partner other than the Original
Limited Partners may be admitted as a Substituted Limited Partner and a
transferee of a portion of the interest of a Limited Partner may be admitted as
an Additional Limited Partner only with the consent of the General Partner,
which consent may be given or withheld by the General Partner in its sole and
absolute discretion. The failure or refusal by the General Partner to otherwise
permit a transferee of any such interests to become an Additional Limited
Partner or a Substituted Limited Partner shall not give rise to any cause of
action against the Partnership or the General Partner. Subject to the foregoing,
an Assignee shall not be admitted as an Additional Limited Partner or a
Substituted Limited Partner until and unless it furnishes to the General Partner
(i) evidence of acceptance, in form and substance satisfactory to the General
Partner, of all the terms, conditions and applicable obligations of this
Agreement, including the power of attorney granted in Section 2.4 hereof; (ii) a
Partner Schedule executed by such Assignee; and (iii) such other documents and
instruments as may be reasonably required or advisable to effect such Assignee's
admission as a Substituted Limited Partner or an Additional Limited Partner, as
the case may be.

     B. A transferee who has been admitted as an Additional Limited Partner or 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.

                                      47

<PAGE>

     C. Upon the admission of an Additional Limited Partner or a Substituted
Limited Partner, the General Partner shall amend the Partner Schedule(s) to
eliminate, if necessary, the name and address of the predecessor of a
Substituted Limited Partner. In addition, the Additional Limited Partner or
Substituted Limited Partner and the General Partner shall execute a Partner
Schedule with respect to such Additional Limited Partner or Substituted Limited
Partner, which Partner Schedule shall supersede, to the extent necessary, the
Partner Schedule for the predecessor of the Additional Limited Partner or
Substituted Limited Partner.

     Section 11.5 Assignees

     If the General Partner does not consent to the admission of any Permitted
Transferee under Section 11.3 hereof or Section 11.4 hereof as an Additional
Limited Partner or a Substituted Limited Partner, 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 Gross Income, Net Income, Net Loss and other items of income,
gain, loss, deduction and credit of the Partnership attributable to the
Partnership Units assigned to such transferee and the rights to Transfer the
Partnership Units provided in this Article 11, but shall not be deemed to be a
Holder of Partnership Units for any other purpose under this Agreement (other
than as expressly provided in Section 8.6 hereof with respect to a Qualifying
Party that becomes a Tendering Party), and shall not be entitled to effect a
Consent or vote with respect to such Partnership Units on any matter presented
to the Limited Partners for approval (which such right shall remain with the
transferor Limited Partner). In the event that 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.

     Section 11.6 General Provisions

     A. No Limited Partner may withdraw from the Partnership other than as a
result of a Transfer permitted pursuant to this Article 11 where such transferee
was admitted as a Substituted Limited Partner, or pursuant to a Redemption (or
acquisition by the General Partner) of all of its Partnership Units under
Section 8.6 hereof.

     B. Any Limited Partner who shall Transfer all of its Partnership Units in a
Transfer (i) permitted pursuant to this Article 11 where such transferee was
admitted as a Substituted Limited Partner; (ii) pursuant to the exercise of its
rights to effect a Redemption of all of its Partnership Units under Section 8.6
hereof; or (iii) to the General Partner, whether or not pursuant to Section
8.6.B hereof, shall cease to be a Limited Partner.

     C. If any Partnership Unit is Transferred in compliance with the provisions
of this Article 11, or is redeemed by the Partnership or acquired by the General
Partner pursuant to Section 8.6 hereof, on any day other than the first day of a
Fiscal Year, then Gross Income, Net Income, Net Loss, each item thereof and all
other items of income, gain, loss, deduction and credit attributable to such
Partnership Unit for such Fiscal Year shall be allocated to the transferor
Partner or the Tendering Party, as the case may be, and, in the case of a
Transfer or assignment other than a Redemption, to the transferee Partner
(including the General Partner in the case of an

                                      48

<PAGE>

acquisition of Partnership Units pursuant to Section 8.6.B hereof) or Assignee,
by taking into account their varying interests during the Fiscal Year in
accordance with Code Section 706(d), using the "Daily Proration" or "Interim
Closing of the Books" method or another permissible method selected by the
General Partner and approved by the transferor Partner and the transferee
Partner, which approval will not unreasonably be withheld. Solely for purposes
of making such allocations, the General Partner, in its sole and absolute
discretion, may determine that each of such items for the calendar month in
which a Transfer occurs shall be allocated to the transferee Partner or Assignee
and none of such items for the calendar month in which a Transfer or a
Redemption occurs shall be allocated to the transferor Partner or the Tendering
Party, as the case may be, if such Transfer occurs on or before the fifteenth
(15th) day of the month; otherwise such items for such calendar month shall be
allocated to the transferor. All distributions of Available Cash attributable to
such Partnership Unit with respect to which the Partnership Record Date is
before the date of such Transfer, assignment or Redemption shall be made to the
transferor Partner or the Tendering Party, as the case may be, and, in the case
of a Transfer other than a Redemption, all distributions of Available Cash
thereafter attributable to such Partnership Unit shall be made to the transferee
Partner or Assignee.

     D. In addition to any other restrictions on Transfer herein contained, in
no event may any Transfer or assignment of a Partnership Interest by any Partner
(exclusive of any acquisition of Partnership Units by the General Partner or any
other acquisition of Partnership Units by the Partnership) be made:

          (1)  to any person or entity who lacks the legal right, power or
     capacity to own a Partnership Interest;

          (2) in violation of applicable law;

          (3) 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;

          (4) in the event that such Transfer could, in the good faith opinion
     of the General Partner, cause the General Partner to cease to comply with
     the REIT Requirements;

          (5) if such Transfer could, in the opinion of counsel to the
     Partnership or the General Partner, cause a termination of the Partnership,
     in either case for federal or state income tax purposes (except as a result
     of the Redemption (or acquisition by the General Partner) of Partnership
     Units held by the Original Limited Partners);

          (6) if such Transfer could, in the opinion of legal counsel to the
     Partnership, cause the Partnership either (i) to cease to be classified as
     a partnership or (ii) to be classified as a publicly traded partnership, in
     either case for federal income tax purposes (except as a result of the
     Redemption (or acquisition by the General Partner) of Partnership Units
     held by the Original Limited Partners);

          (7) if such Transfer could, in the opinion of legal 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-

                                      49

<PAGE>

     Interest" (as defined in ERISA Section 3(14)) or a "Disqualified Person"
     (as defined in Code Section 4975(c));

          (8) if such Transfer could, in the opinion of legal 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;

          (9) if such Transfer requires the registration of such Partnership
     Interest pursuant to any applicable federal or state securities laws;

          (10) if such Transfer could cause the Partnership to have more than
     one hundred (100) Partners (including as Partners for such purpose those
     Persons indirectly owning an interest in the Partnership through another
     partnership, a limited liability company, subchapter S corporation or a
     grantor trust, if substantially all the value of such Person's interest in
     any such entity is attributable to such entity's interest (direct or
     indirect) in the Partnership);

          (11) if such Transfer causes the Partnership (as opposed to the
     General Partner) to become a reporting company under the Exchange Act; or

          (12) if such Transfer subjects the Partnership to regulation under the
     Investment Company Act of 1940, the Investment Advisors Act of 1940 or
     ERISA, each as amended.

     Section 11.7 Incremental Costs

     The General Partner shall be entitled to be reimbursed for its reasonable
incremental administrative costs incurred in connection with making payments to,
preparing reports and statements for, effecting Redemptions with respect to and
otherwise servicing all transferees of Preferred Partnership Units, whether
directly or indirectly and, whether or not such transferee is an Additional
Limited Partner, a Substituted Limited Partner or an Assignee, over and above
the amount of such costs incurred in connection with providing such services to
the General Partner and an aggregate of ten (10) additional Holders or
transferees of Preferred Partnership Units. Such costs may include a reasonable
allocation of the General Partner's internal costs and expenses, including a pro
rata portion of the salaries or wages, benefits and overhead of its employees
engaged in servicing the Holders and transferees. The General Partner may effect
such reimbursement by deducting the reimbursable amount from the distributions
otherwise payable to the Holders of the Preferred Partnership Units pursuant to
Section 5.1(1) hereof.

the Partnership as an Additional Limited Partner or a Substitute Limited Partner
shall furnish to the General Partner (i) evidence of acceptance, in form and
substance satisfactory to the General Partner, of all of the terms, conditions
and applicable of this Agreement, including the power of attorney granted in
Section 2.4 hereof; (ii) a Partner Schedule executed by such Person; and (iii)
such other documents or instruments as may be reasonably required with respect
to Designated Parties, or may be required in the sole and absolute discretion of
the General Partner with respect to other Persons, in order to effect such
Party's or other Person's admission as an Additional Limited Partner or a
Substitute Limited Partner. Additional Limited Partners may be admitted to the
Partnership upon prior written consent of a Majority in Interest of the Original
Limited Partners and such written consent will not unreasonably be withheld.

     B. If any Additional Limited Partner or Substituted Limited Partner is
admitted to the Partnership on any day other than the first day of a Fiscal
Year, then Gross Income, Net Income, Net Loss, each item thereof and all other
items of income, gain, loss, deduction and credit allocable among Partners and

with Code Section 706(d), using the "Interim Closing Of The Books" method or
another permissible method selected by the General Partner and approved by a
Majority in Interest of the Limited Partners, which approval shall not be
unreasonably withheld. Solely for purposes of making such allocations, each of
such items for the calendar month in which an admission of any Additional
Limited Partner or Substituted Limited Partner occurs shall be allocated among
all the Partners and Assignees, including such Additional Limited Partner or
Substituted Limited Partner, in accordance with the principles described in

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 hereof.

     No Person shall be admitted to the Partnership as a Substituted Limited
Partner or an Additional Limited Partner if the effect of such admission would
be to cause the Partnership to have more than one hundred (100) Partners
including as Partners for such purpose those Persons indirectly owning an
interest in the Partnership through another partnership, a limited liability
company, a subchapter S corporation or a grantor trust, if substantially all the
value of such Person's interest in any such entity is attributable to such
entity's interest (direct or indirect) in the Partnership, or otherwise cause
the Partnership to become a reporting company under the Exchange Act.

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

     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 shall
continue the business of the Partnership without dissolution. However, 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"):

          (1) the expiration of its term as provided in Section 2.5 hereof;

          (2) an event of withdrawal, as defined in the Act (including
     bankruptcy), of the sole General Partner unless, within ninety (90) days
     after the withdrawal, a "Majority in Interest" (as such phrase is used in
     Section 17-801(3) of the Act) of the remaining Partners and the Original
     Limited Partners agree in writing, in its sole and absolute discretion, to
     continue the business of the Partnership and to the appointment, effective
     as of the date of withdrawal, of a successor General Partner;

          (3) entry of a decree of judicial dissolution of the Partnership
     pursuant to the provisions of the Act;

          (4) the occurrence of a Terminating Capital Transaction; or

          (5) the Redemption (or acquisition by the General Partner) of all
     Partnership Units other than Partnership Units held by the General Partner.

     Section 13.2 Winding Up

     A. Upon the occurrence of a Liquidating Event, the Partnership shall
continue solely for the purposes of effecting any Redemptions or the acquisition
by the General Partner of Tendered Units and winding up its affairs in an
orderly manner, liquidating its assets and satisfying the claims of its
creditors and Partners. After the occurrence of a Liquidating Event, no Partner
shall take any action that is inconsistent with, or not necessary to or
appropriate for, such purposes. The General Partner (or, in the event that there
is no remaining General Partner or the General Partner has dissolved, become
bankrupt within the meaning of the Act or ceased to

                                      52

<PAGE>

operate, any Person elected by a Majority in Interest of the Limited Partners
(the General Partner or such other Person being referred to herein as 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 satisfaction of all of the Partnership's debts and
     liabilities to creditors other than the Partners and their Assignees
     (whether by payment or the making of reasonable provision for payment
     thereof);

          (2) Second, to the satisfaction of all of the Partnership's debts and
     liabilities to the General Partner other than Partner Loans (whether by
     payment or the making of reasonable provision for payment thereof),
     including amounts due as reimbursements under Section 7.5 hereof;

          (3) Third, to the payment of the accrued but unpaid amounts payable to
     the Holders of Preferred Partnership Units, PARI PASSU in accordance with
     their ownership of such Units, pursuant to Section 5.1(1) hereof;

          (4) Fourth, to the satisfaction of all of the Partnership's debts and
     liabilities to the other Partners and any Assignees, including the
     repayment of Partner Loans, pari passu in accordance with their ownership
     of such Loans (whether by payment or the making of reasonable provision for
     payment thereof); and

          (5) The balance, if any, to the General Partner, the Limited Partners
     and any Assignees in accordance with and in proportion to their positive
     Capital Account balances, after giving effect to all contributions,
     distributions and allocations for all periods.

                                      53

<PAGE>

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13.

     B. Notwithstanding the provisions of Section 13.2.A hereof that 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 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 hereof, 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.

     C. In the event that the Partnership is "Liquidated" within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant
to this Article 13 to the Partners and Assignees that have positive Capital
Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2) to the
extent of, and in proportion to, their respective positive Capital Account
balances. If any Partner has a deficit balance in its Capital Account (after
giving effect to all contributions, distributions and allocations for all
taxable years, including the year during which such liquidation occurs), such
Partner shall have no obligation to make any contribution to the capital of the
Partnership with respect to such deficit, and such deficit shall not be
considered a debt owed to the Partnership or to any other Person for any purpose
whatsoever. In the sole and absolute discretion of the General Partner or the
Liquidator, a pro rata portion of the distributions that would otherwise be made
to the Partners pursuant to this Article 13 may be 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
order of priority set forth in Section 13.2.A hereof as soon as practicable.

     Section 13.3 Deemed Contribution and Distribution

     Notwithstanding any other provision of this Article 13, in the event that
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.

     Section 13.4 Rights Of Limited Partners

     Except as provided in Section 8.6 hereof, (i) each Partner shall look
solely to the assets of the Partnership for the return of its Capital
Contribution and (ii) no Partner shall have the right or power to demand or
receive property other than cash from the Partnership. Except as provided in

                                      54

<PAGE>

Sections 5.1 and 13.2.A hereof, no Partner shall have priority over any other
Partner as to the return of its Capital Contributions, distributions or
allocations.

     Section 13.5 Notice Of Dissolution

     In the event that a Liquidating Event occurs or an event occurs that would,
but for an election or objection by one or more Partners pursuant to Section
13.1 hereof, result in a dissolution of the Partnership, the General Partner
shall, within thirty (30) days thereafter, provide written notice thereof to
each of the Partners and, in the General Partner's sole and absolute discretion
or as required by the Act, to all other parties with whom the Partnership
regularly conducts business, and the General Partner may, or, if required by the
Act, shall, publish notice thereof in a newspaper of general circulation in each
place in which the Partnership regularly conduct business.

     Section 13.6 Cancellation Of Certificate Of Limited Partnership

     Upon the completion of the liquidation of the Partnership as provided in
Section 13.2 hereof, the Partnership shall be terminated, a certificate of
cancellation shall be filed with the Commonwealth of Virginia, all
qualifications of the Partnership as a foreign limited partnership or
association in jurisdictions other than the Commonwealth of Virginia shall be
cancelled and such other actions as may be necessary to terminate the
Partnership shall be taken.

     Section 13.7 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 hereof, in order to 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 14.1 Procedures For Actions And Consents Of Partners

Agreement, including Sections 7.3 or 7.4 hereof, or otherwise pursuant to
applicable law, are subject to the procedures set forth in this Article 14.

     Section 14.2 Amendments

     Amendments to this Agreement may be proposed by the General Partner or by a
Majority in Interest of the Limited Partners. Following any such proposal by the
General Partner, the General Partner shall submit the proposed amendment to the
Limited Partners. The General Partner may seek the written consent of the
Limited Partners on any other proposed amendment or call a meeting to vote
thereon and to transact any other business that the General Partner may deem
appropriate. For purposes of obtaining a written Consent, the General Partner
may require a response within a reasonable specified time, but not less than
fifteen (15) days, and failure to respond in such time period shall constitute a
Consent that is consistent with the

                                      55

<PAGE>

General Partner's recommendation with respect to the proposal; provided,
however, that an action shall become effective at such time as requisite
Consents are received even if prior to such specified time.

     Section 14.3 Meetings Of 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 a
Majority in Interest of the Limited Partners. The call shall state the nature of
the business to be transacted. Notice of any such meeting shall be given to all
Partners not less than seven (7) days nor more than thirty (30) days prior to
the date of such meeting. Partners may vote in person or by proxy at such
meeting. Whenever the vote or Consent of Limited Partners is permitted or
required under this Agreement, such vote or Consent may be given at a meeting of
Partners or may be given in accordance with the procedure prescribed in Section
14.3.B hereof.

     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 Partners holding a majority of the Partnership
Units (or such other 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 Partners
holding a majority of the Partnership Units (or such other percentage as is
expressly required by this Agreement). Such consent shall be filed with the
General Partner. An action so taken shall be deemed to have been taken at a
meeting held on the effective date so certified.

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

     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. Meetings of Partners may be conducted in the same manner as
meetings of the General Partner's shareholders and may be held at the same time
as, and as part of, the meetings of the General Partner's shareholders.

and among the Partners with respect to the subject matter of this Agreement and
the rights, interests and obligations of the Partners with respect to the

     Section 15.8 Invalidity Of Provisions

     If any provision of this Agreement is or becomes invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not be affected thereby.

     Section 15.9 Limitation To Preserve REIT Status

     Notwithstanding anything else in this Agreement, to the extent that the
amount paid, credited, distributed or reimbursed by the Partnership to, for or
with respect to any REIT Partner or its officers, directors, employees or
agents, whether as a reimbursement, fee, expense or indemnity (a "REIT
Payment"), would constitute gross income to the REIT Partner for purposes of
Code Section 856(c)(2) or Code Section 856(c)(3), then, notwithstanding any
other provision of this Agreement, the amount of such REIT Payments, as selected
by the General Partner in its discretion from among items of potential
distribution, reimbursement, fees, expenses and indemnities, shall be reduced
for any Fiscal Year so that the REIT Payments, as so reduced, to, for or with
respect to such REIT Partner shall not exceed the lesser of:

          (1) an amount equal to the excess, if any, of (i) four and nine-
     tenths percent (4.9%) of the REIT Partner's total gross income (but
     excluding the amount of any REIT Payments) for the Fiscal Year that is
     described in subsections (A) through (H) of Code Section 856(c)(2) over
     (ii) the amount of gross income (within the meaning of Code

                                      58
<PAGE>

     Section 856(c)(2)) derived by the REIT Partner from sources other than
     those described in subsections (A) through (H) of Code Section 856(c)(2)
     (but not including the amount of any REIT Payments); or

          (2) an amount equal to the excess, if any, of (i) twenty-four percent
     (24%) of the REIT Partner's total gross income (but excluding the amount of
     any REIT Payments) for the Fiscal Year that is described in subsections (A)
     through (I) of Code Section 856(c)(3) over (ii) the amount of gross income
     (within the meaning of Code Section 856(c)(3)) derived by the REIT Partner
     from sources other than those described in subsections (A) through (I) of
     Code Section 856(c)(3) (but not including the amount of any REIT Payments);

provided, however, that REIT Payments in excess of the amounts set forth in
clauses (a) and (b) above may be made if the General Partner, as a condition
precedent, obtains an opinion of tax counsel that the receipt of such excess
amounts shall not adversely affect the REIT Partner's ability to qualify as a
REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a
consequence of the limitations set forth in this Section 15.9, such REIT
Payments shall carry over and shall be treated as arising in the following
Fiscal Year. The purpose of the limitations contained in this Section 15.9 is to
prevent any REIT Partner from failing to qualify as a REIT under the Code by
reason of such REIT Partner's share of items, including distributions,
reimbursements, fees, expenses or indemnities, receivable directly or indirectly
from the Partnership, and this Section 15.9 shall be interpreted and applied to
effectuate such purpose.

     Section 15.10 No Partition

     No Partner nor any successor-in-interest to a Partner shall have the right
while this Agreement remains in effect to have any property of the Partnership
partitioned, or to file a complaint or institute to any proceeding at law or in
equity to have such property of the Partnership partitioned, and each Partner,
on behalf of itself and its successors and assigns hereby waives any such right.
It is the intention of the Partners that the rights of the parties hereto and
their successors-in-interest to Partnership property, as among themselves, shall
be governed by the terms of this Agreement, and that the rights of the Partners
and their successors-in-interest shall be subject to the limitations and
restrictions as set forth in this Agreement.

     Section 15.11 No Third-Party Rights Created Hereby

     The provisions of this Agreement are solely for the purpose of defining the
interests of the Partners, inter se; and no other person, firm or entity (i.e.,
a party who is not a signatory hereto or a permitted successor to such signatory
hereto) shall have any right, power, title or interest by way of subrogation or

<PAGE>

4.2  ADDITIONAL COVENANTS OF THE GENERAL PARTNER

     The General Partner hereby represents, warranty covenants and agrees that:

     A. The General Partner shall cause the Partnership to elect the
"traditional method," as set forth in Regulations Section 1.704-3(b), with
respect to the "built-in gain" (as defined in Regulations Section
1.704-3(a)(3)(ii)) on the Real Property and any "Replacement Property" (as
defined below). For purposes of determining as of the Effective Date the
built-in gain on each component of the Real Property, the Fair Market Value of
each component of the Real Property shall be established by agreement between
the General Partner and the Original Limited Partners.

     B. During the period beginning on the Effective Date and ending on the
second (2nd) anniversary of the Effective Date (the "Lockout Period"), neither
the Partnership or the General Partner nor any Affiliate of the Partnership or
the General Partner shall voluntarily transfer (or permit the voluntary transfer
of) all or any portion of, or any direct or indirect interest in, the Real
Property, any Replacement Property or any partnership (or membership) interest
in any entity that owns all or a portion of the Real Property or any Replacement
Property in a transaction that would result in the recognition of any taxable
income or gain by any Original Limited Partner for Federal income tax purposes.
The General Partner and the Original Limited Partners agree that, during the
Lockout Period, the Partnership may transfer all or any portion of the Real
Property in a transaction qualifying for nonrecognition of gain under Code
Section 1031 (or any successor statute) (an "Exchange"), provided that (a) the
Exchange does not result in the recognition of any taxable income or gain by any
Original Limited Partner for Federal income tax purposes and (b) the real
property acquired in the Exchange (the "Replacement Property") shall remain
subject to the provisions of this Section 4 as if the Replacement Property were
all or a portion of the Real Property. The General Partner and the Original
Limited Partners acknowledge and agree that an involuntary transfer of all or a
portion of the Real Property or any Replacement Property could occur by way of
condemnation, casualty or foreclosure. In the event of an involuntary transfer
of all or a portion of the Real Property or any Replacement Property by way of
(i) a condemnation or casualty, the General Partner shall, on behalf of the
Partnership, use its reasonable good faith efforts to minimize or avoid the
recognition of any taxable income or gain by any Original Limited Partner for
Federal income tax purposes from the condemnation or casualty through the use of
Code Section 1033 (or any successor statute) or (ii) foreclosure, the General
Partner shall, on behalf of the Partnership, use its reasonable good faith
efforts to minimize or avoid the recognition of any taxable income or gain by
any Original Limited Partner for Federal income tax purposes from the
foreclosure through the use of Code Section 1031 (or any successor statute).
After the Lockout Period, the General Partner shall, on behalf of the
Partnership, use reasonable good faith efforts to structure any refinancing of
indebtedness or disposition of all or any portion of the Real Property or any
Replacement Property so as to minimize the recognition of any taxable income or
gain by any Original Limited Partner for federal income tax purposes.

     C. Subject to the terms and provisions of Section 4.2(D) hereof:

        (a) During the Lockout Period, the Partnership shall maintain
outstanding, without prepayment or other reduction, nonrecourse indebtedness

                                      62

<PAGE>

(within the meaning of Regulations Section 1.752-1(a)(2)) secured by the Real
Property (or any Replacement Property) in an aggregate amount equal to the
aggregate outstanding principal balance of all indebtedness secured by the Real
Property immediately prior to the Effective Date (the "Existing Debt"); and

          (b) Neither the General Partner nor the Partnership shall (i) cause or
permit any Person to directly or indirectly guarantee, or otherwise become
liable for the payment of, all or a portion of the Existing Debt or any
"Replacement Debt" (as defined below), (ii) otherwise take or permit any action
that would result in all or a portion of the Existing Debt or any Replacement
Debt to fail to be treated as nonrecourse indebtedness (within the meaning of
Regulations Section 1.752-1(a)(2)), or (iii) amend or otherwise alter the
provisions of Section 6.3.C of the Agreement in a manner that results in a
smaller share of the "Excess Nonrecourse Liabilities" of the Partnership (within
the meaning of Regulations Section 1.752-3(a)(3)) being allocable to the
Original Limited Partners.

     D. The terms and provisions of Section 4.2(C) hereof shall not apply to the
extent of:

          (a) Scheduled principal payments (but not any prepayments and any
principal payments due as a result of any acceleration or default of the
Existing Debt or any Replacement Debt (except in the event of a condemnation,
casualty or foreclosure, in which case the provisions of Section 4.2(D)(c)
hereof shall apply)) made in accordance with the requirements of the Existing
Debt or any Replacement Debt;

          (b) Payments of principal made in connection with the refinancing of
the Existing Debt or any Replacement Debt, provided that (i) such refinancing
conforms with the terms of Section 4.2(E) hereof and (ii) after giving effect to
such refinancing, the Partnership would be in compliance with the terms of
Section 4.2(C) hereof (after taking into account principal payments permitted
under clause (a) above); and

          (c) Any payment of principal made (or deemed to be made) in connection
with the condemnation, casualty or foreclosure of all or a portion of the Real
Property or any Replacement Property.

     E. During the Lockout Period, the Partnership may refinance the Existing
Debt or any Replacement Debt with new debt (the "Replacement Debt") only if the
new debt (a) is secured by the Real Property or any Replacement Property, (b)
has a principal amortization schedule which equals or is longer than the current
amortization schedule of the Existing Debt or Replacement Debt (not including
any bullet or balloon payments at maturity) that is being refinanced, and (c) is
(i) nonrecourse indebtedness within the meaning of Regulations Section
1.752-1(a)(2) and (ii) qualified nonrecourse financing within the meaning of
Code Section 465(b)(6)(B). In addition to the foregoing, a Replacement Debt
shall have a principal amount that equals or exceeds the outstanding principal
balance of the Existing Debt or the Replacement Debt that is being refinanced;
provided, however, that any Replacement Debt with a principal amount greater
than the outstanding principal balance of the Existing Debt or the Replacement
Debt that is being refinanced shall not result in the Real Property or any
Replacement Property having a Loan To Value Ratio immediately after such
refinancing that exceeds ninety percent (90%).

<PAGE>

     F. In the event that the Partnership or the General Partner removes the
Existing Debt or disposes of all or a portion of the Real Property during the
Lockout Period (the "Action"), the General Partner shall advance up to the
lesser of (a) $1,000,000 (in the aggregate) or (b) the Built in Tax Amount as a
loan to the Original Limited Partners on an interest-free basis with such loan
commencing on April 1 of the year subsequent to the Action and such loan
maturing on April 15, 2004. For purposes of this section, the "Built in Tax
Amount" shall mean, for each Original Limited Partner (treating such Original
Limited Partner as if it were taxable as an individual) the Code Section 704(c)
built in gain realized by the Original Limited Partner calculated at the highest
applicable marginal tax rates then in effect for federal and state income tax
purposes.

     G. For purposes of this Section 4, the term "Original Limited Partner"
shall include (a) the ultimate owners, at whatever level, that are taxpayers or
taxpaying entities for Federal income tax purposes, of any Original Limited
Partner, or its constituent partners or members at whatever level, as the case
may be, as determined by looking-through each Original Limited Partner, or
constituent partner or member at whatever level, as the case may be, that is a
partnership, limited liability company or other pass-through entity for Federal
income tax purposes and (b) any transferee controlled by such Person who
acquired an ownership interest in Partnership Units in a transaction in which
the transferee's basis is determined, in whole or in part, by reference to the
basis of the transferor.

                                    ---------
                      EXAMPLES REGARDING ADJUSTMENT FACTOR
                      ------------------------------------

     For purposes of the following examples, it is assumed that (a) the
Adjustment Factor in effect on June 30, 2001 is 1.0 and (b) on July 1, 2001 (the
"Partnership Record Date" for purposes of these examples), prior to the events
described in the examples, there are 100 REIT Shares issued and outstanding.

EXAMPLE 1

     On the Partnership Record Date, the General Partner declares a dividend on
its outstanding REIT Shares in REIT Shares. The amount of the dividend is one
REIT Share paid in respect of each REIT Share owned. Pursuant to Paragraph (i)
of the definition of "Adjustment Factor," the Adjustment Factor shall be
adjusted on the Partnership Record Date, effective immediately after the stock
dividend is declared, as follows:

                        1.0 X (200 DIVIDED BY 100) = 2.0

Accordingly, the Adjustment Factor after the stock dividend is declared is 2.0.

EXAMPLE 2

     On the Partnership Record Date, the General Partner distributes options to
purchase REIT Shares to all holders of its REIT Shares. The amount of the
distribution is one option to acquire one REIT Share in respect of each REIT
Share owned. The strike price is $4.00 a share. The Value of a REIT Share on the
Partnership Record Date is $5.00 per share. Pursuant to Paragraph (ii) of the
definition of "Adjustment Factor," the Adjustment Factor shall be adjusted on
the Partnership Record Date, effective immediately after the options are
distributed, as follows:

1.0 X ((100 + 100) DIVIDED BY (100 + (100 * $4.00) DIVIDED BY $5.00)) = 1.1111

Accordingly, the Adjustment Factor after the options are distributed is 1.1111.
If the options expire or become no longer exercisable, then the retroactive
adjustment specified in Paragraph (ii) of the definition of "Adjustment Factor"
shall apply.

EXAMPLE 3

     On the Partnership Record Date, the General Partner distributes assets to
all holders of its REIT Shares. The amount of the distribution is one asset with
a Fair Market Value of $1.00 in respect of each REIT Share owned. It is also
assumed that the assets do not relate to assets received by the General Partner
pursuant to a pro rata distribution by the Partnership. The Value of a REIT
Share on the Partnership Record Date is $5.00 a share. Pursuant to Paragraph
(iii) of the definition of "Adjustment Factor," the Adjustment Factor shall be
adjusted on the Partnership Record Date, effective immediately after the assets
are distributed, as follows:

                 1.0 X ($5.00 DIVIDED BY ($5.00 - $1.00)) = 1.25

Accordingly, the Adjustment Factor after the assets are distributed is 1.25.
