Section 4.1.   Capital Contributions of the Initial Members

     At the time of their respective execution of this Agreement, the Members
shall make Capital Contributions as set forth in Exhibit A to this Agreement.
The Members shall own Managing Member Units and Non-Managing Member Units, as
applicable, in the amounts set forth on Exhibit A.  Except as required by law or
as otherwise provided in Sections 4.2 and 4.3, no Member shall be required or
permitted to make any additional Capital Contributions or loans to the Company.

Section 4.2.   Loans by Third Parties

     The Company may not incur or assume Debt without the Consent of the Non-
Managing Members, except for Refinancing Debt.

Section 4.3.   Additional Capital Contributions

     A.   General.  The Managing Member may, at any time and from time to time,
determine that the Company requires additional funds ("Additional Funds") for
the operation of the Company.  Additional Funds may be raised by the Company in
accordance with the terms of this Section 4.3.  No Person, including, without
limitation, any Member or Assignee, shall have any preemptive, preferential,
participation or similar right or rights to subscribe for or acquire any
Membership Interest.
     B.   Additional Member Contributions.  The Managing Member on behalf of the
Company and with the Consent of the Non-Managing Members may raise all or any
portion of the Additional Funds by making additional Capital Contributions.
Subject to the terms of this Section 4.3 and to the definition of "Gross Asset
Value," the Managing Member shall determine in good faith the amount, terms and
conditions of such additional Capital Contributions.  In addition, the Managing
Member shall be solely responsible for making additional Capital Contributions
to the Company in amounts sufficient to fund all necessary capital additions,
tenant improvements and leasing commissions relating to the Real Properties.
The Managing Member shall receive additional Managing Member Units only in
consideration for additional capital contributions made by the Managing Member
in an aggregate amount in excess of Five Hundred Thousand Dollars ($500,000) to
fund capital additions that will add rentable space to the Properties.
     
     C.   Timing of Additional Capital Contributions.  If additional Capital
Contributions are made by Members on any day other than the first day of a
Fiscal Year, then Net Income, Net Loss, each item thereof and all other items of
income, gain, loss, deduction and credit allocable among Members and Assignees
for such Fiscal Year, if necessary, shall be allocated among such Members and
Assignees by taking into account their varying interests during the Fiscal Year
in accordance with Code Section 706(d), using the "interim closing of the books"
or "daily proration" method or another permissible method selected by the
Managing Member.
     
     Section 4.4.   No Interest; No Return

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


                                   ARTICLE 5.
                                  DISTRIBUTIONS

     Section 5.1.   Requirement and Characterization of Distributions

     A.   The Managing Member shall cause the Company to distribute quarterly on
the LLC Distribution Date all Available Cash generated by the Company during the
quarter most recently ended prior to the LLC Distribution Date as follows:
          
          (1)  First, to the holders of the Non-Managing Member Units (whether
     held by a Non-Managing Member or the Managing Member), in accordance with
     their relative Preferred Return Shortfalls, until the Preferred Return
     Shortfall for each holder of Non-Managing Member Units is zero, provided,
     however, that in the event the number of Non-Managing Member Units is
     reduced pursuant to Section 5.6.B hereof, a distribution shall be made
     under this Section 5.1.A(1) on the first (and only the first) LLC
     Distribution Date occurring after such reduction to the holder or holders
     of the Reduction Units in an amount determined by multiplying the amount
     that would have been distributed on such LLC Distribution Date under this
     Section 5.1.A(1) in respect of the Reduction Units had they been
     outstanding on such LLC Distribution Date (the "Subsequent Distribution
     Date") by a fraction, the numerator of which shall be the number of days in
     the period commencing on the LLC Distribution Date most recently preceding
     the Reduction Date (the "Prior Distribution Date") and ending on the
     Reduction Date and the denominator of which shall be the number of days in
     the period commencing on the Prior Distribution Date and ending on the
     Subsequent Distribution Date.
     
          (2)  Second, to the Managing Member, the Managing Member's Capital
     Return Shortfall, until the Managing Member's Capital Return Shortfall is
     zero;

          (3)  Third, to the Managing Member the Amortization until the
     Amortization Shortfall is zero; and

          (4)  Fourth, 17% of the remaining balance, if any, to the holders of
     the Non-Managing Member Units (whether held by a Non-Managing Member or the
     Managing Member) in proportion to their outstanding Non-Managing Member
     Units as of the LLC Record Date; and 83% of such remaining balance to the
     holder of the Managing Member Units as of the LLC Record Date.

Set forth on Exhibit D are examples of the application of the provisions of this
Section 5.1.A based upon assumed amounts of Available Cash and other assumptions
reflected in Exhibit D.

     B.   The Managing Member shall take such reasonable efforts, as determined
by it in its sole and absolute discretion and consistent with its qualification
as a REIT, to cause the Company to distribute sufficient amounts to enable the
Managing Member to pay stockholder dividends that will (a) satisfy the
requirements for qualifying as a REIT under the Code and Regulations ("REIT
Requirements"), and (b) except to the extent the Managing Member elects, in its
sole discretion, not to make such distributions, avoid any federal income or
excise tax liability of the Managing Member.

     Section 5.2.   Distributions in Kind

     No right is given to any Member to demand and receive property other than
cash.  The Managing Member may determine, in its sole and absolute discretion,
to make a distribution in kind to the Members of Company assets, and such assets
shall be distributed in such a fashion as to ensure that the fair market value
is distributed and allocated in accordance with Articles 5 and 6 hereof.
     
     Section 5.3.   Amounts Withheld

     Each Member hereby authorizes the Company to withhold from or pay on behalf
of or with respect to such Member any amount of federal, state, local or foreign
taxes that the Managing Member determines that the Company is required to
withhold or pay with respect to any amount distributable or allocable to such
Member pursuant to this Agreement, including, without limitation, any taxes
required to be withheld or paid by the Company 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 Member shall constitute a loan by the Company to
such Member, which loan shall be repaid by such Member within 15 days after
notice from the Managing Member that such payment must be made unless (i) the
Company withholds such payment from a distribution that would otherwise be made
to the Member or (ii) the Managing Member determines, in its reasonable
discretion, that such payment may be satisfied out of the Available Cash of the
Company that would, but for such payment, be distributed to the Member.  Any
amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be treated
as having been distributed to such Member.  Each Member hereby unconditionally
and irrevocably grants to the Company a security interest in such Member's
Membership Interest to secure such Member's obligation to pay to the Company any
amounts required to be paid pursuant to this Section 5.3.  In the event that a
Member fails to pay any amounts owed to the Company pursuant to this Section 5.3
when due, the Managing Member may, in its sole and absolute discretion, elect to
make the payment to the Company on behalf of such defaulting Member, and in such
event shall be deemed to have loaned such amount to such defaulting Member and
shall succeed to all rights and remedies of the Company as against such
defaulting Member (including, without limitation, the right to receive
distributions).  Any amounts payable by a Member hereunder shall bear interest
at the base rate on corporate loans at large United States money center
commercial banks, as published from time to time in the Wall Street Journal,
plus four (4) percentage points (but not higher than the maximum lawful rate)
from the date such amount is due (i.e., 15 days after demand) until such amount
is paid in full.  Each Member shall take such actions as the Company or the
Managing Member shall request in order to perfect or enforce the security
interest created hereunder.

     Section 5.4.   Distributions Upon Liquidation

     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 Company shall be
distributed to the Members in accordance with Section 13.2 hereof.

     Section 5.5.   Restricted Distributions

     Notwithstanding any provision to the contrary contained in this Agreement,
neither the Company nor the Managing Member, on behalf of the Company, shall
make a distribution to any Member on account of its Membership Interest or
interest in LLC Units if such distribution would violate Section 18-607 of the
Act or other applicable law.

     Section 5.6.   Distributions of Proceeds from Sale of Real Properties and
                    Refinancing Debt

     A.   In the event of a taxable disposition of some, but not all, of the
Real Properties and in the event the Company incurs Refinancing Debt, the
Managing Member shall cause the Company to distribute the net proceeds from such
Refinancing Debt, as the case may be, as follows:
     
     (1)  First, to the holders of the Non-Managing Member Units (whether held
by a Non-Managing Member or by the Managing Member) from the net proceeds of the
taxable disposition, in proportion to the number of outstanding Non-Managing
Member Units so held, 28.3% of the Shared Appreciation Amounts relating to the
Real Properties subject to the taxable disposition;
     
     (2)  Second, to the holders of the Managing Member Units from the net
proceeds of the taxable disposition, the balance of the Shared Appreciation
Amounts relating to the Real Properties subject to the taxable disposition;
     
     (3)  Third, to the Managing Member an amount equal to (i) the amount of any
tenant improvements and leasing commissions funded by the Managing Member
through additional Capital Contributions made pursuant to Section 4.3 subsequent
to the Effective Date with respect to the Real Property or Real Properties which
are the subject of the taxable disposition or secure the repayment of the
Refinancing Debt, less (ii) the amount distributed to the Managing Member under
Section 5.1.A(3) hereof in respect of the amount described in the foregoing
clause (i); and
     
     (4)  Fourth, the remaining balance, if any, to the Members pro rata to
their holdings of Managing Member Units and Non-Managing Member Units.
     
     B.   The number of LLC Units outstanding on the date of a distribution
pursuant to Section 5.6.A above will be reduced on the date of the distribution
(the "Reduction Date") by the aggregate number of LLC Units (the "Total Units")
determined by dividing the aggregate amount of the distributions so made by the
Value on the Reduction Date.  The Non-Managing Member Units shall be reduced by
a number of LLC Units (rounded down to the nearest whole unit) (the "Reduction
Units") determined by multiplying the number of Total Units by a fraction, the
numerator of which is the total number of Non-Managing Member Units outstanding
and the denominator of which is the total number of Non-Managing Member Units
and Managing Member Units outstanding.  The Reduction Units shall be allocated
(as closely as practicable in whole units) among the holders of Non-Managing
Member Units in accordance with their respective holdings of Non-Managing Member
Units.  The Managing Member Units shall be reduced by a number of Managing
Member Units equal to the difference between the number of Total Units and the
number of Reduction Units.  In no event, however, shall the number of Non-
Managing Member Units be reduced below nine (9) Non-Managing Member Units and in
no event shall the number of Managing Member Units be reduced below eighty-five
(85) Managing Member Units.  To reflect the foregoing reduction, each Member
shall return to the Managing Member the certificate evidencing the Reduction
Units allocated to him or it or the Managing Member Units so reduced which will
be canceled and a new certificate evidencing the reduced number of Managing
Member Units or Non-Managing Member Units shall be immediately issued to such
Member by the Managing Member on behalf of the Company.
     
     C.   The Company shall have no obligation to incur Refinancing Debt for the
purposes of making distributions pursuant to this Section 5.6 or for any other
purpose.

     Section 5.7.   Offset

     Except for offsets authorized by the Loan and Security Agreement, neither
the Company nor the Managing Member shall be entitled to offset against any
distribution payable to the Non-Managing Members pursuant to this Article 5 and
Article 13 any amounts owing or otherwise alleged to be owing to the Company or
the Managing Member; provided, however, that the Managing Member shall be
entitled, at its option, to offset against amounts otherwise payable to Non-
Managing Members hereunder (including, without limitation, amounts payable
pursuant to Section 5.1.A(1) hereof and Section 13.2 hereof) amounts authorized
for offset by the Loan and Security Agreement.  Any amounts so offset pursuant
to the foregoing shall be deemed for all purposes to have been distributed or
paid to the Non-Managing Members as required by this Agreement, including for
purposes of calculating Preferred Return Shortfalls.

                                   ARTICLE 6.
                                   ALLOCATIONS
                                        
     Section 6.1.   Timing and Amount of Allocations of Net Income and Net Loss
     
     Net Income and Net Loss of the Company shall be determined and allocated
with respect to each Fiscal Year of the Company as of the end of each such year.
Except as otherwise provided in this Article 6, an allocation to a Member of a
share of Net Income or Net Loss shall be treated as an allocation of the same
share of each item of income, gain, loss or deduction (collectively "Tax Items")
that is taken into account in computing Net Income or Net Loss.

     Section 6.2.   General Allocations

     A.   Operating Net Income and Net Loss.  Except as otherwise provided in
Sections 6.2.C or 6.3:

          (1)  Net Income, other than Net Income attributable to a disposition
     of any or all of the Real Properties, shall first be allocated to each Non-
     Managing Member in an amount equal to the distributions received by such
     Member pursuant to Section 5.1.A, less any amounts of Net Income previously
     allocated to such Member pursuant to this Section 6.2.A(1).
     
          (2)  All remaining Net Income and Net Loss, other than Net Income or
     Net Loss attributable to a disposition of any or all of the Real
     Properties, shall be allocated to the Managing Member.

     B.   Net Income and Net Loss from the Disposition of Real Properties.
Except as otherwise provided in Sections 6.2.C or 6.3:

          (1)  Net Income attributable to a disposition of any or all of the
     Real Properties shall be allocated to each Member in an amount equal to the
     distributions received by such Member pursuant to Section 5.6.A(1) or (2),
     less any amounts of Net Income previously allocated to such Member pursuant
     to this Section 6.2.B(1).
     
          (2)  Thereafter, any remaining Net Income or Net Loss attributable to
     the disposition of any or all of the Real Properties shall be allocated to
     the Members in proportion to their LLC Units.

     C.   Net Income and Net Loss Upon Liquidation.  If a Liquidating Event
occurs in a Fiscal Year, Net Income or Net Loss (or, if necessary, separate
items of income, gain, loss and deduction) for such Fiscal Year and any Fiscal
Years thereafter shall, subject to Section 6.3, be allocated among the Members
in such amounts and priorities so that the amounts distributed to each of the
Members pursuant to Section 13.2.A(3) upon the liquidation of the Company will
equal the Intended Liquidating Distributions.

     D.   Prorations.  If the amount of Net Income or Net Loss available for
allocation under any subsection of Sections 6.2.A or B above is less than the
aggregate amount to be allocated pursuant to the applicable subsection (assuming
sufficient Net Income or Net Loss was available), such allocation shall be made
to the Members pro rata to the total amounts to be so allocated pursuant to such
subsection.

     Section 6.3.   Additional Allocation Provisions

     A.   Regulatory Allocations.
          
               (1)  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 Company Minimum Gain during any Fiscal Year, each
          Member shall be specially allocated items of Company income and gain
          for such year (and, if necessary, subsequent years) in an amount equal
          to such Member's share of the net decrease in Company 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 Member pursuant thereto.  The
          items to be allocated shall be determined in accordance with
          Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2).  This Section
          6.3.A(1) 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.
     
               (2)  Member Minimum Gain Chargeback. Except as otherwise provided
          in Regulations Section 1.704-2(i)(4) or in Section 6.3.A(1) hereof, if
          there is a net decrease in Member Minimum Gain attributable to a
          Member Nonrecourse Debt during any Fiscal Year, each Member who has a
          share of the Member Minimum Gain attributable to such Member
          Nonrecourse Debt, determined in accordance with Regulations Section
          1.704-2(i)(5), shall be specially allocated items of Company income
          and gain for such year (and, if necessary, subsequent years) in an
          amount equal to such Member's share of the net decrease in Member
          Minimum Gain attributable to such Member Nonrecourse Debt, determined
          in accordance with Regulations Section 1.704-2(i)(4).  Allocations
          pursuant to the previous sentence shall be made in proportion to the
          respective amounts required to be allocated to each Member pursuant
          thereto.  The items to be so allocated shall be determined in
          accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2).
          This Section 6.3.A(2) 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.

               (3)  Member Nonrecourse Deductions. Any Member Nonrecourse
          Deductions for any Fiscal Year shall be specially allocated to the
          Member(s) who bears the economic risk of loss with respect to the
          Member Nonrecourse Debt to which such Member Nonrecourse Deductions
          are attributable, in accordance with Regulations Section 1.704-2(i).

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

               (5)  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 Member, such allocation of Net Loss shall be
          reallocated among the other Members in accordance with their
          respective LLC Units, subject to the limitations of this Section
          6.3.A(5).

               (6)  Section 754 Adjustment. To the extent that an adjustment to
          the adjusted tax basis of any Company 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 Member in complete
          liquidation of its interest in the Company, 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 Members in accordance with their LLC Units
          in the event that Regulations Section 1.704-1(b) (2)(iv)(m)(2)
          applies, or to the Members to whom such distribution was made in the
          event that Regulations Section 1.704-1(b) (2)(iv)(m)(4) applies.

               (7)  Curative Allocations.  The allocations set forth in Sections
          6.3.A(1) through (6) 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 Sections 6.1 and 6.2 hereof, the
          Regulatory Allocations shall be taken into account in allocating other
          items of income, gain, loss and deduction among the Members 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 Member shall be
          equal to the net amount that would have been allocated to each such
          Member if the Regulatory Allocations had not occurred.
          
          B.   Allocation of Excess Nonrecourse Liabilities.  For purposes of
     determining a Member's proportional share of the "excess nonrecourse
     liabilities" of the Company within the meaning of Regulations Section 1.752
     -3(a)(3), each Member's interest in Company profits shall be such Member's
     Percentage Interest.

          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 of the
     Company's Tax Items shall be allocated among the Members 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 Property
     that is contributed to the Company with a Gross Asset Value that varies
     from its basis in the hands of the contributing Member immediately
     preceding the date of contribution shall be allocated among the Members for
     income tax purposes pursuant to the "traditional method" as described in
     Regulations Section 1.704-3(b), utilizing the allocations set forth on
     Exhibit C-1 (subject to modification upon the agreement of the Managing
     Member and the Non-Managing Members).  In the event that the Gross Asset
     Value of any Company asset is adjusted pursuant to 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 and this Section 6.4.B., pursuant to any
     method permitted under Regulations Section 1.704-3 as selected by the
     Managing Member

     Section 6.5.   Other Provisions
     
          A.   Other Allocations.  In the event that (i) any modifications are
     made to the Code or any Regulations, (ii) any changes occur in any case law
     applying or interpreting the Code or any Regulations, (iii) the IRS changes
     or clarifies the manner in which it applies or interprets the Code or any
     Regulations or any case law applying or interpreting the Code or any
     Regulations or (iv) the IRS adjusts the reporting of any of the
     transactions contemplated by this Agreement which, in each case, either
     (a) requires allocations of items of income, gain, loss, deduction or
     credit or (b)  requires reporting of any of the transactions contemplated
     by this Agreement in a manner different from that set forth in this Article
     6, the Managing Member is hereby authorized to make new allocations or
     report any such transactions (as the case may be) in reliance of the
     foregoing, and such new allocations and reporting shall be deemed to be
     made pursuant to the fiduciary duty of the Managing Member to the Company
     and the other Members, and no such new allocation or reporting shall give
     rise to any claim or cause of action by any Member.
          
          B.   Consistent Tax Reporting.  The Members 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 Loss and other items of income,
     gain, loss, deduction and credit for federal, state and local income tax
     purposes.
          
     Section 6.6.   Amendments to Allocation to Reflect Issuance of Additional
                    Membership Interests

     In the event that the Company issues additional Membership Interests to the
Managing or any Additional Member pursuant to Article 4 hereof, the Managing
Member shall make such revisions to this Article 6 as it determines are
necessary to reflect the terms of the issuance of such additional Membership
Interests, including making preferential allocations to certain classes of
Membership Interests.
                                        
                                   ARTICLE 7.

perform the above-mentioned agreements and transactions on behalf of the Company
without any further act, approval or vote of the Non-Managing Members,
notwithstanding any other provision of this Agreement (except as provided in
Section 7.3 hereof), the Act or any applicable law, rule or regulation.  The
execution, delivery or performance by the Managing Member or the Company of any
agreement authorized or permitted under this Agreement shall not constitute a
breach by the Managing Member of any duty that the Managing Member may owe the
Company or the Members or any other Persons under this Agreement or of any duty
stated or implied by law or equity.
     
     C.   At all times from and after the date hereof, the Managing Member may

tax consequences to any Member (including the Managing Member) of any action
taken by it.  The Managing Member and the Company shall not have liability to a
Member under any circumstances as a result of an income tax liability incurred
by such Member as a result of an action (or inaction) by the Managing Member
pursuant to its authority under this Agreement so long as the action or inaction
is taken in good faith.  The provisions of this Section 7.1.D shall not affect
the obligations of the Managing Member under Section 7.3.E hereof.

     Section 7.2.   Certificate of Formation

     To the extent that such action is determined by the Managing Member to be
reasonable and necessary or appropriate, the Managing Member shall file
amendments to and restatements of the Certificate and do all the things to
maintain the Company as a limited liability company under the laws of the State
of Delaware and each other state, the District of Columbia or any other
jurisdiction in which the Company may elect to do business or own property.
Subject to the terms of Section 8.5.A(4) hereof, the Managing Member shall not
be required, before or after filing, to deliver or mail a copy of the
Certificate or any amendment thereto to any Member.  The Managing Member 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 liability company in the
State of Delaware and any other state, or the District of Columbia or other
jurisdiction in which the Company may elect to do business or own property.
     
     Section 7.3.   Restrictions on Managing Member's Authority

          (5)  enter into any contract, mortgage, loan or other agreement that
     expressly prohibits or restricts, or has the effect of prohibiting or
     restricting, the ability of (a) the Managing Member or the Company from

     Member from exercising its rights to an Exchange in full, except, in either
     case, with the written consent of such Member affected by the prohibition.
          
     B.   The Managing Member shall not, without the prior Consent of the Non-
Managing Members undertake or have the authority to do or undertake, on behalf

exclusive power to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

          (4)  to satisfy any requirements, conditions, or guidelines contained
     in any order, directive, opinion, ruling or regulation of a federal or

The Managing Member will provide at least ten (10) days' notice to the Non-

7.3.C before the action is taken.

     D.   Notwithstanding Section 7.3.B and 7.3.C hereof, this Agreement shall
not be amended with respect to any Member adversely affected, and no action may

limited liability of a Non-Managing Member, (iii) alter rights of the Member to
receive distributions pursuant to Article 5 or Section 13.2.A(4), or the

and Section 7.3.C(3) hereof), (iv) materially alter or modify the rights to an
Exchange as set forth in Section 8.6, and related definitions hereof or (v)

the Consent specified in such section.  Any such amendment or action consented
to by any Member shall be effective as to that Member, notwithstanding the
absence of such consent by any other Member.
     
     E.   So long as the Initial Non-Managing Members own Non-Managing Member
Units representing at least 3% of the aggregate number of LLC Units issued on

take any of the following actions without the prior Consent of the Non-Managing
Members:
          (1)  dissolve the Company for a period of five years from the
     Effective Date; or

     period of five years from the Effective Date.

     Section 7.4.   Compensation of the Managing Member
     
     The Managing Member shall not be compensated for its services as the
manager of the Company.  Distributions, payments and allocations to which the
Managing Member may be entitled in its capacity as the Managing Member shall not
constitute compensation for services rendered by the Managing Member as provided
in this Agreement (including the provisions of Articles 5 and 6 hereof).


     Section 7.5.   Other Business of Managing Member

     The Managing Member shall devote to the Company such time as may be

performance of such duties.  The Managing Member may engage independently or
with others in other business ventures of every nature and description,
including, without limitation, the ownership of other properties and the making
or management of other investments.  Nothing in this Agreement shall be deemed
to prohibit the Managing Member or any Affiliate of the Managing Member from
dealing, or otherwise engaging in business with, Persons transacting business
with the Company, or from providing services related to the purchase, sale,
financing, management, development or operation of real or personal property and
receiving compensation therefor, not involving any rebate or reciprocal
arrangement that would have the effect of circumventing any restriction set
forth herein upon dealings with the Managing Member or any Affiliate of the
Managing Member.  Neither the Company nor any Member shall have any right by
virtue of this Agreement or the relationship created 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 Company,
shall not be deemed wrongful or improper.

     Section 7.6.   Contracts with Affiliates

     Except as expressly permitted by this Agreement, neither the Managing
Member nor any of its Affiliates, directly or indirectly, shall sell, transfer
or convey any property to, or purchase any property from, or borrow funds from,
or lend funds to, the Company or engage in any other transaction with the
Company, except upon terms determined by the Managing Member in good faith to be
fair and reasonable and comparable to terms that could be obtained from an
unaffiliated party in an arm's length transaction.

     Section 7.7.   Indemnification
     
     A.   To the fullest extent permitted by applicable law, the Company shall
indemnify each Indemnitee from and against any and all losses, claims, damages,
liabilities, joint or several, expenses (including, without limitation,
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 Company ("Actions") as set forth in this
Agreement in which such Indemnitee may be involved, or is threatened to be
involved, as a party or otherwise unless it is established that: (i) the act or
omission of the Indemnitee was material to the matter giving rise to the
proceeding and either was committed in bad faith or was the result of active and
deliberate dishonesty; (ii) the Indemnitee actually received an improper
personal benefit in money, property or services; or (iii) in the case of any
criminal proceeding, the Indemnitee had reasonable cause to believe that the act
or omission was unlawful.  Without limitation the foregoing indemnity shall
extend to any liability of any Indemnitee, pursuant to a loan guaranty or
otherwise, for any indebtedness of the Company or any Subsidiary of the Company
(including, without limitation, any indebtedness which the Company or any
Subsidiary of the Company has assumed or taken subject to), and the Managing
Member is hereby authorized and empowered, on behalf of the Company, to enter
into one or more indemnity agreements consistent with the provisions of this
Section 7.7 in favor of any Indemnitee having or potentially having liability
for any such indebtedness. The termination of any proceeding by judgment, order
or settlement does not create a presumption that the Indemnitee did not meet the
requisite standard of conduct set forth in this Section 7.7.A.  The termination
of any proceeding by conviction or upon a plea of nolo contendere or its
equivalent, or an entry of an order of probation prior to judgment, creates a
rebuttable presumption that the Indemnitee acted in a manner contrary to that
specified in this Section 7.7.A with respect to the subject matter of such
proceeding.  Any indemnification pursuant to this Section 7.7 shall be made only
out of the assets of the Company, and any insurance proceeds from the liability
policy covering the Managing Member and any Indemnitees, and neither the
Managing Member nor any Non-Managing Member shall have any obligation to
contribute to the capital of the Company or otherwise provide funds to enable
the Company to fund its obligations under this Section 7.7.

     B.   Reasonable 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 Company as incurred by the Indemnitee in
advance of the final disposition of the Action upon receipt by the Company 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 Company
as authorized in Section 7.7.A has been met, and (ii) a written undertaking by
or on behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.
     
     C.   The indemnification provided by this Section 7.7 shall be in addition
to any other rights to which an Indemnitee or any other Person may be entitled
under any agreement, pursuant to any vote of the Members, as a matter of law or
otherwise, and shall continue as to an Indemnitee who has ceased to serve in
such capacity unless otherwise provided in a written agreement with such
Indemnitee or in the writing pursuant to which such Indemnitee is indemnified.
     
     D.   The Company may, but shall not be obligated to, purchase and maintain
insurance, on behalf of any of the Indemnitees and such other Persons as the
Managing Member shall determine, against any liability that may be asserted
against or expenses that may be incurred by such Person in connection with the
Company's activities, regardless of whether the Company would have the power to
indemnify such Person against such liability under the provisions of this
Agreement.
     
     E.   In no event may an Indemnitee subject any of the Members to personal
liability by reason of the indemnification provisions set forth in this
Agreement.
     
     F.   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.
     
     G.   The provisions of this Section 7.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.  Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the
Company'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.
     
     H.   If and to the extent any reimbursements to the Managing Member
pursuant to this Section 7.7 constitute gross income to the Managing Member (as
opposed to the repayment of advances made by the Managing Member on behalf of
the Company) such amounts shall constitute guaranteed payments within the
meaning of Code Section 707(c), shall be treated consistently therewith by the
Company and all Members, and shall not be treated as distributions for purposes
of computing the Members' Capital Accounts.

     Section 7.8.   Liability of the Managing Member

     A.   Notwithstanding anything to the contrary set forth in this Agreement,
neither the Managing Member nor any of its directors or officers shall be liable
or accountable in damages or otherwise to the Company, any Members 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 Managing Member or such director or officer acted in good faith.

     B.   The Non-Managing Members and the Managing Member expressly acknowledge
that the Managing Member is acting for the benefit of the Company, the Members
and the Managing Member's shareholders collectively, that the Managing Member is
under no obligation to give priority to the separate interests of the Members or
the Managing Member's shareholders (including, without limitation, the tax
consequences to Members, Assignees or the Managing Member's shareholders) in
deciding whether to cause the Company to take (or decline to take) any actions
and that the Managing Member shall not be liable to the Company or to any Member
for monetary damages for losses sustained, liabilities incurred, or benefits not
derived by Non-Managing Members in connection with such decisions, provided that
the Managing Member has acted in good faith and has not breached its express
covenants set forth in this Agreement.

     C.   Subject to its obligations and duties as Managing Member set forth in
Section 7.1.A hereof, the Managing Member 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.  The Managing Member
shall not be responsible for any misconduct or negligence on the part of any
such agent appointed by it in good faith.
     
     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 Managing Member's, and its officers' and directors',
liability to the Company and the Non-Managing Members under this Section 7.8 as
in effect immediately prior to such amendment, modification or repeal with
respect to claims arising from or relating to matters occurring, in whole or in
part, prior to such amendment, modification or repeal, regardless of when such
claims may arise or be asserted.

Section 7.10.  Other Matters Concerning the Managing Member

     A.   The Managing Member 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.
     
     B.   The Managing Member 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 Managing Member reasonably believes to be within
such Person's professional or expert competence shall be conclusively presumed
to have been done or omitted in good faith and in accordance with such opinion.
     
     C.   The Managing Member shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and a duly appointed attorney or attorneys-in-fact.  Each such attorney
shall, to the extent provided by the Managing Member in the power of attorney,
have full power and authority to do and perform all and every act and duty that
is permitted or required to be done by the Managing Member hereunder.
     
     D.   Notwithstanding any other provisions of this Agreement or the Act, any
action of the Managing Member on behalf of the Company or any decision of the
Managing Member to refrain from acting on behalf of the Company undertaken in
the good faith belief that such action or omission is necessary or advisable in
order (i) to protect the ability of the Managing Member to continue to qualify
as a REIT, (ii) for the Managing Member otherwise to satisfy the REIT
Requirements or (iii) to allow the Managing Member to avoid incurring any
liability for taxes under Section 857 or Section 4981 of the Code, is expressly
authorized under this Agreement and is deemed approved by all of the Non-
Managing Members.

     Section 7.10.  Title to Company Assets
     
     Title to Company assets, whether real, personal or mixed and whether
tangible or intangible, shall be deemed to be owned by the Company as an entity,
and no Member, individually or collectively with other Members or Persons, shall
have any ownership interest in such Company assets or any portion thereof.  All
Company assets shall be recorded as the property of the Company in its books and
records, irrespective of the name in which legal title to such Company assets is
held.

     Section 7.11   Reliance by Third Parties

     Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Company shall be entitled to assume that the Managing Member
has full power and authority, without the consent or approval of any other
Member or Person, to encumber, sell or otherwise use in any manner any and all
assets of the Company and to enter into any contracts on behalf of the Company,
and take any and all actions on behalf of the Company, and such Person shall be
entitled to deal with the Managing Member as if it were the Company's sole party
in interest, both legally and beneficially.  Each Non-Managing Member hereby
waives any and all defenses or other remedies that may be available against such
Person to contest, negate or disaffirm any action of the Managing Member in
connection with any such dealing.  In no event shall any Person dealing with the
Managing Member or its representatives be obligated to ascertain that the terms
of this Agreement have been complied with or to inquire into the necessity or
expediency of any act or action of the Managing Member or its representatives.
Each and every certificate, document or other instrument executed on behalf of
the Company by the Managing Member or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and delivery of such certificate, document
or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Company and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Company.

                        RIGHTS AND OBLIGATIONS OF MEMBERS

except as expressly provided in this Agreement or under the Act.

     Section 8.2.   Managing of Business

     No Non-Managing Members or Assignee (other than the Managing Member, any of
its Affiliates or any officer, director, employee, partner, agent or trustee of
the Managing Member, the Company 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 Company's business transact any business in the
Company's name or have the power to sign documents for or otherwise bind the
Company.  The transaction of any such business by the Managing Member, any of
its Affiliates or any officer, director, employee, partner, agent or trustee of
the Managing Member, the Company or any of their Affiliates, in their capacity
as such, shall not affect, impair or eliminate the limitations on the liability
of the Non-Managing Members or Assignees under this Agreement.

     Section 8.3.   Outside Activities of Members

     Subject to any agreements entered into by a Member or its Affiliates with
the Managing Member, the Company or a Subsidiary (including, without limitation,

entitled to and may have business interests and engage in business activities in
addition to those relating to the Company, including business interests and
activities that are in direct or indirect competition with the Company or that
are enhanced by the activities of the Company.  Neither the Company nor any
Member shall have any rights by virtue of this Agreement in any business
ventures of any Member or Assignee.  Subject to such agreements, none of the
Members nor any other Person shall have any rights by virtue of this Agreement
or the relationship established hereby in any business ventures of any other
Person (other than the Managing Member, to the extent expressly provided
herein), and such Person shall have no obligation pursuant to this Agreement,
subject to any agreements entered into by a Member or its Affiliates with the
Managing Member, the Company or a Subsidiary, to offer any interest in any such
business ventures to the Company, any Member or any such other Person, even if
such opportunity is of a character that, if presented to the Company, any Member
or such other Person, could be taken by such Person.

     Section 8.4.   Return of Capital

     Section 8.5.   Rights of Non-Managing Members Relating to the Company
     
     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 Non-Managing Member shall
have the right, for a purpose reasonably related to such Non-Managing Member's
Membership Interest in the Company, upon written demand and at such Non-Managing
Member's own expense:
     
          (1)  to obtain a copy of (i) the most recent annual and quarterly
     reports filed with the SEC by the Managing Member pursuant to the Exchange
     Act and (ii) each report or other written communication sent to the
     shareholders of the Managing Member;
          
          (2)  to obtain a copy of the Company'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 Member;
          
          (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 Member and that each Member has agreed to contribute in
     the future, and the date on which each became a Member.
     
     B.   The Company shall notify any Non-Managing Member of the then current
Adjustment Factor or any change made to the Adjustment Factor or to the REIT
Shares Amount within 30 days following such change or adjustment.
     
     C.   Notwithstanding any other provision of this Section 8.5, the Managing
Member may keep confidential from the Non-Managing Members, for such period of
time as the Managing Member determines in its sole and absolute discretion to be
reasonable, any information that (i) the Managing Member believes to be in the
nature of trade secrets or other information the disclosure of which the
Managing Member in good faith believes is not in the best interests of the
Company or could damage the Company or its business or (ii) the Company or the
Managing Member is required by law or by agreements with unaffiliated third
parties to keep confidential.

     Section 8.6.   Exchange Rights
     
     A.   On or after the date one year after the Effective Date, each Non-
Managing Member shall have the right (subject to the terms and conditions set
forth herein) to require the Managing Member to acquire all or a portion of the
Non-Managing Member Units held by such Non-Managing Member (such Non-Managing
Member Units being hereafter called "Tendered Units") in exchange
(an "Exchange") for, at the election of and in the sole and absolute discretion
of the Managing Member, either the Cash Amount or a number of REIT Shares equal
to the REIT Shares Amount payable on the Specified Exchange Date.  Any Exchange
shall be exercised pursuant to a Notice of Exchange delivered to the Managing
Member by the Non-Managing Member exercising the Exchange right (the "Tendering
Party").  No Tendering Party shall be entitled to tender Non-Managing Member
Units pursuant hereto for exchange on a Specified Exchange Date in an amount
less than the lesser of (i) 1,000 Non-Managing Member Units, or (ii) all of the
Non-Managing Member Units then owned by the Tendering Party.  On the Specified
Exchange Date, the Tendering Party shall sell the Tendered Units to the Managing
Member in exchange for, at the election of and in the sole and absolute
discretion of the Managing Member, either the Cash Amount or a number of REIT
Shares equal to the REIT Shares Amount.  In the event that on the LLC
Distribution Date most recently preceding the Specified Exchange Date there
shall have been a Preferred Return Shortfall remaining in respect of the
Tendered Units following the payments made on such LLC Distribution Date
pursuant to Section 5.1 hereof, the Managing Member shall pay the Tendering
Party in cash on the Specified Exchange Date the amount of such Preferred Return
Shortfall remaining on such LLC Distribution Date in respect of the Tendered
Units.  Any Tendered Units so acquired by the Managing Member pursuant to this
Section 8.6.A shall be held by the Managing Member as Non-Managing Member Units
with all the rights and preferences relating thereto as provided in this
Agreement.  The Tendering Party shall submit (i) such information, certification
or affidavit as the Managing Member may reasonably require in connection with
the Ownership Limit and (ii) in the event the REIT Shares issuable upon such
Exchange are not registered for resale by the Tendering Party under the
Securities Act, such written representations, investment letters, legal opinions
or other instruments necessary, in the Managing Member's view, to effect
compliance with the Securities Act.  If a Cash Amount is to be delivered upon
the Exchange, the Cash Amount shall be delivered as a certified check payable to
the Tendering Party or, in the Managing Member's sole discretion, in immediately
available funds.  If REIT Shares are to be delivered upon the Exchange, the REIT
Shares Amount shall be delivered by the Managing Member as duly authorized,
validly issued, fully paid and nonassessable REIT Shares (and, if applicable,
Rights), free of any pledge, lien, encumbrance or restriction, other than the
Ownership Limit and, in the event the REIT Shares issuable upon such Exchange
are not registered for resale by the Tendering Party under the Securities Act,
the Securities Act and relevant state securities or "blue sky" laws.  The
Tendering Party shall be deemed the owner of such REIT Shares and Rights for all
purposes, including, without limitation, rights to vote or consent, receive
dividends, and exercise rights, as of the Specified Exchange Date.  REIT Shares
issued upon an acquisition of the Tendered Units by the Managing Member pursuant
to this Section 8.6.A may contain such legends regarding restrictions on
transfer or ownership to protect the Managing Member's tax status as a REIT and
in the event the REIT Shares issuable upon such Exchange are not registered for
resale by the Tendering Party under the Securities Act, restrictions under the
Securities Act and applicable state securities laws as the Managing Member in
good faith determines to be necessary or advisable in order to ensure compliance
with such laws.
     
     B.   Notwithstanding the provisions of Section 8.6.A hereof, no Non-
Managing Member shall have any right to tender for Exchange (whether for the
REIT Shares Amount or the Cash Amount) any Excess LLC Units held by such Non-
Managing Member.  The Managing Member shall have no obligation to acquire Excess
LLC Units, whether for the REIT Shares Amount or the Cash Amount.
     
     C.   Notwithstanding anything herein to the contrary, with respect to any
Exchange pursuant to this Section 8.6 each Tendering Party shall continue to own
all LLC Units subject to any Exchange, and be treated as a Member with respect
to such LLC Units for all purposes of this Agreement, until such LLC Units are
transferred to the Managing Member and paid for or exchanged on the Specified
Exchange Date. Until a Specified Exchange Date and an acquisition of the
Tendered Units by the Managing Member pursuant to Section 8.6.A hereof, the
Tendering Party shall have no rights as a shareholder of the Managing Member
with respect to the REIT Shares issuable in connection with such acquisition.

     D.   In connection with an exercise of Exchange rights pursuant to this
Section 8.6, the Tendering Party shall submit the following to the Managing
Member, in addition to the Notice of Exchange:
          
          (1)  A written affidavit, dated the same date as, and accompanying,
     the Notice of Exchange, (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 Exchange, 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 Exchange on the Specified Exchange Date; and
          
          (3)  An undertaking to certify, at and as a condition to the closing
     of the Exchange 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.D(1) or (b)
     after giving effect to the Exchange, neither the Tendering Party nor any
     Related Party shall own REIT Shares in violation of the Ownership Limit.
                                        
                                   ARTICLE 9.

cards, magnetic tape, photographs, micrographics or any other information
storage device, provided that the records so maintained are convertible into
clearly legible written form within a reasonable period of time.
     
     B.   The books of the Company shall be maintained, for financial and tax
reporting purposes, on an accrual basis in accordance with generally accepted
accounting principles, or on such other basis as the Managing Member determines
to be necessary or appropriate.

     Section 9.2.   Fiscal Year

Member of record as of the last day of the calendar quarter, a copy of the

taxable year, the tax information reasonably required by Members for federal and
state income tax reporting purposes.

     Section 10.2.  Tax Elections

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

     Section 10.3.  Tax Matters Partner
     
     A.   The Managing Member shall be designated and shall operate as "Tax
Matters Partner" (as defined in Code Section 6231), to oversee or handle matters
relating to the taxation of the Company.

     B.   The Member designated as "Tax Matters Partner" may make all elections
for federal income and all other tax purposes (including, without limitation,

public accountant(s) as the Managing Member shall retain at the expense of the

     Section 10.4.  Organizational Expenses

     Section 11.1.  Transfer
     
     A.   No part of the interest of a Member shall be subject to the claims of

not be voluntarily or involuntarily alienated or encumbered except as may be
specifically provided for in this Agreement.

     B.   No Membership 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 Membership Interest not made in
accordance with this Article 11 shall be null and void ab initio.

     Section 11.2.  Transfer of Managing Member's Membership Interest
     
     A.   Except in connection with a transaction described in Section 11.2.B,
the Managing Member shall not withdraw from the Company and shall not transfer
all or any portion of its interest in the Company without the Consent of all of
the Non-Managing Members, which may be given or withheld by each Non-Managing
Member in its sole and absolute discretion.  Upon any transfer of the Membership
Interest of the Managing Member in accordance with the provisions of this
Section 11.2, the transferee shall become a Substitute Managing Member for all
purposes herein, and shall be vested with the powers and rights of the
transferor Managing Member, and shall be liable for all obligations and

executed such instruments as may be necessary to effectuate such admission and
to confirm the agreement of such transferee to be bound by all the terms and
provisions of this Agreement with respect to the Membership 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 Managing Member under this Agreement with respect
to such transferred Membership Interest, and such transfer shall relieve the
transferor Managing Member of its obligations under this Agreement accruing
subsequent to the date of such transfer.  In the event the Managing Member
withdraws from the Company, in violation of this Agreement or otherwise, or
otherwise dissolves or terminates, or upon the Incapacity of the Managing
Member, all of the remaining Members may elect to continue the Company business
by selecting a Substitute Managing Member in accordance with the Act.

     B.   The Managing Member shall not engage in any merger, consolidation or
other combination with or into another person, sale of all or substantially all
of its assets or any reclassification, recapitalization or change of its
outstanding equity interests (a "Termination Transaction"), unless either
(i) the Termination Transaction has been approved by the Consent of the Non-
Managing Members or (ii) in connection with the Termination Transaction, all
holders of LLC Units (other than the Managing Member) either will receive, or
will have the right to elect to receive, for each LLC Unit an amount of cash,
securities, or other property equal to the amount that would have been paid to
the holder had the LLC Unit been Exchanged for REIT Shares pursuant to Section
8.6 hereof immediately prior to the consummation of the Termination Transaction;
provided, however, that, if, in connection with the Termination Transaction, a
purchase, tender or exchange offer shall have been made to and accepted by the
holders of more than fifty percent (50%) of the outstanding REIT Shares, each
Member shall receive, or shall have the right to elect to receive, the greatest
amount of cash, securities, or other property which such Member would have
received had it exchanged its LLC Units for REIT Shares pursuant to Section 8.6
immediately prior to the expiration of such purchase, tender or exchange offer
and had thereupon accepted such purchase, tender or exchange offer.

     Section 11.3.  Non-Managing Members' Rights to Transfer

     A.   Right of First Refusal.  If any Non-Managing Member proposes to
Transfer all or any portion of its Membership Interest for consideration, it
shall give notice thereof (the "Transfer Notice") to the Managing Member.  The
Transfer Notice shall include the name and identity of the prospective
transferee, the date upon which such Transfer is to be consummated, which shall
not be more than 180 days after the date of the Transfer Notice, and the price
and terms on which the Non-Managing Member proposes to Transfer its Membership
Interest.  For a period of ten (10) Business Days following its receipt of the
Transfer Notice, the Managing Member shall have an option to purchase the entire
Membership Interest offered at the price and on the terms set forth in the
Transfer Notice.  The failure of the Managing Member to exercise its option
shall constitute a waiver thereof by the Managing Member with respect to the
transaction described in the Transfer Notice.  Should the option be exercised by
the Managing Member, the sale to the Managing Member shall be consummated on or
before the later of (a) 30 days after the date on which the option was exercised
or (b)  the date specified in the Transfer Notice as the date upon which the
proposed Transfer was to be consummated, for the price and on the terms set
forth in the Transfer Notice, and the transferring Non-Managing Member shall
execute and deliver all documents necessary to effectuate the Transfer of the
Membership Interest to the Managing Member.  Should the option not be exercised
by the Managing Member, the Non-Managing Member may transfer the Membership
interested so offered, on or before the date specified in the Transfer Notice,
for the price, on the terms and to the transferee specified in the Transfer
Notice, subject to the limitations and provisions set forth in this Article 11.
Should such a Transfer not be timely consummated as aforesaid, then the
Membership Interest shall again become subject to the foregoing right of first
refusal.  If the right of first refusal described in this Section 11.3.A is
exercised by the Managing Member, then the costs of the transaction, including
without limitation recording fees, escrow costs and attorneys' fees reasonably
incurred by the Company in connection with the Transfer, shall be shared equally
by the Managing Member and the transferring Non-Managing Member.  If the
transferring Non-Managing Manager transfers its Membership Interest to a
purchaser other than the Managing Member, all costs of the transaction shall be
borne by the transferring Non-Managing Member.  The transferring Non-Managing
Manager shall deliver all appropriate transfer documents, which shall be in form
and content satisfactory to the Managing Member.

     B.   Conditions to Transfer.  It is a condition to any Transfer otherwise
permitted hereunder that the transferee assume by operation of law or express
agreement all of the obligations of the transferor Member under this Agreement
with respect to such Transferred Membership Interest.  Notwithstanding the
foregoing, any transferee of any Transferred Membership Interest shall be
subject to the Ownership Limits and any and all ownership limitations contained
in the Charter.  Any transferee, whether or not admitted as a Substituted
Member, shall take subject to the obligations of the transferor hereunder.
Unless admitted as a Substituted Member, 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.

     C.   Incapacity.  If a Non-Managing Member is subject to Incapacity, the
executor, administrator, trustee, committee, guardian, conservator or receiver
of such Non-Managing Member's estate shall have all the rights of a Non-Managing
Member, but not more rights than those enjoyed by other Non-Managing Members,
for the purpose of settling or managing the estate, and such power as the
Incapacitated Non-Managing Member possessed to Transfer all or any part of its
interest in the Company.  The Incapacity of a Non-Managing Member, in and of
itself, shall not dissolve or terminate the Company.

     D.   Opinion of Counsel.  In connection with any Transfer of a Membership
Interest, the Managing Member shall have the right to receive an opinion of
counsel reasonably 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 Company or the Membership 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 Company or the LLC Units, the
Managing Member may prohibit any Transfer by a Member of Membership Interests
otherwise permitted under this Section 11.3.
     E.   Adverse Tax Consequences.  No Transfer by a Member of its Membership
Interests (excluding any Exchange pursuant to Section 8.6) may be made to any
Person if (i) in the opinion of legal counsel for the Company, it could result
in the Company being treated as an association taxable as a corporation for
federal income tax or for state income or franchise tax purposes, (ii) in the
opinion of legal counsel for the Company, it could adversely affect the ability
of the Managing Member to continue to qualify as a REIT or could subject the
Managing Member to any additional taxes under Code Section 857 or Code Section
4981 or (iii) 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 (as determined in the sole discretion of the
Managing Member).
     
     F.   Transfers to Lenders.  No Transfer of any LLC Units may be made to a
lender to the Company or any Person who is related (within the meaning of
Section 1.752-4(b)  of the Regulations) to any lender to the Company whose loan
constitutes a Nonrecourse Liability, without the consent of the Managing Member,
in its sole and absolute discretion; provided that, as a condition to such
consent, the lender will be required to enter into an arrangement with the
Company and the Managing Member to redeem or exchange for the REIT Shares Amount
any LLC Units in which a security interest is held simultaneously with the time
at which such lender would be deemed to be a member in the Company for purposes
of allocating liabilities to such lender under Code Section 752.

     G.   Pledge of Non-Managing Member Units.  A Non-Managing Member shall be
entitled to pledge the Non-Managing Member Units owned by him or it to a lender
as security for a loan made by the lender to the Non-Managing Member.  Subject
to compliance with the Ownership Limit and Section 11.3.F hereof, the Non-
Managing Member Units so pledged may be Transferred to the lender, and the
lender, at its option, shall become a Substituted Member in respect of the Non-
Managing Member Units so Transferred to it, upon foreclosure of the pledge or
other exercise of the rights of the lender as a secured party so long as the
lender represents to the Company and the Managing Member, in form and substance
satisfactory to the Managing Member in its reasonable discretion, that it is an
accredited investor within the meaning of Regulation D under the Securities Act
and that it is acquiring its interest in the Non-Managing Member Units for
investment only and not with a view to the distribution of the Non-Managing
Member Units in violation of the Securities Act.

     H.   Distribution of Non-Managing Member Units Upon Dissolution of
Cambridge Medical Center of San Diego, LLC.  Cambridge Medical Center of San
Diego, LLC, a Non-Managing Member, shall be entitled to Transfer Non-Managing
Member Units held by it upon its dissolution and liquidation so long as each
party so receiving Non-Managing Member Units represents to the Company, in form
and substance satisfactory to the Managing Member in its reasonable discretion,
that it, he or she (i) is an "accredited investor" within the meaning of
Regulation D under the Securities Act, and (ii) is acquiring the Non-Managing
Member Units for investment only and not with a view to the distribution of the
Non-Managing Member Units in violation of the Securities Act.


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

     B.   A transferee who has been admitted as a Substituted Member in
accordance with this Article 11 shall have all the rights and powers and be
subject to all the restrictions and liabilities of a Member under this
Agreement.  The admission of any transferee as a Substituted Member shall be
subject to the transferee executing and delivering to the Company an acceptance
of all of the terms and conditions of this Agreement (including without
limitation, the provisions of Section 2.4 and such other documents or
instruments as may be required to effect the admission).

     C.   Upon the admission of a Substituted Member, the Managing Member shall
amend Exhibit A to reflect the name, address, Capital Account, number of LLC
Units and Percentage Interest of such Substituted Member and to eliminate or
adjust, if necessary, the name, address, Capital Account, number of LLC Units
and Percentage Interest of the predecessor of such Substituted Member (and any
other Member, as necessary).

     Section 11.5.  Assignees

     If the Managing Member, in its sole and absolute discretion, does not
consent to the admission of any permitted transferee under Section 11.3 hereof
as a Substituted Member, as described in Section 11.4 hereof, 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 liability
company interest under the Act, including the right to receive distributions
from the Company and the share of Net Income, Net Loss and other items of
income, gain, loss, deduction and credit of the Company attributable to the LLC
Units assigned to such transferee, the rights to Transfer the LLC Units provided
in this Article 11, and the right of Exchange provided in Section 8.6, but shall
not be deemed to be a Member of LLC Units for any other purpose under this
Agreement, and shall not be entitled to effect a Consent or vote with respect to
such LLC Units on any matter presented to the Members for approval (such right
to Consent or vote, to the extent provided in this Agreement or under the Act,
fully remaining with the transferor Member).  In the event that any such
transferee desires to make a further assignment of any such LLC 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 Members desiring to make an assignment of
LLC Units.  The Managing Member shall have no liability under any circumstance
with respect to any Assignee as to which it does not have notice.

Section 11.6.  General Provisions
     
     A.   No Non-Managing Member may withdraw from the Company other than (i) as
a result of a permitted Transfer of all of such Non-Managing Member's LLC Units
in accordance with this Article 11 and the transferee(s) of such LLC Units being
admitting to the Company as a Substituted Member or (ii) pursuant to an Exchange
by the Non-Managing Member of all of its LLC Units under Section 8.6 hereof.

     B.   Any Member who shall Transfer all of its LLC Units in a Transfer
(i) permitted pursuant to this Article 11 where such transferee was admitted as
a Substituted Member or (ii) pursuant to the exercise of its rights to effect an
Exchange of all of its LLC Units under Section 8.6 hereof, shall cease to be a
Member.

     C.   Transfers pursuant to this Article 11 (other than pledges pursuant to
Section 11.3.G Transfers upon dissolution pursuant to Section 11.3.H) may only
be made on the first day of a fiscal quarter of the Company, unless the Managing
Member otherwise agrees.
     
     D.   All distributions of Available Cash attributable to an LLC Unit with
respect to which the LLC Record Date is before the date of a Transfer or an
Exchange of the LLC Unit shall be made to the transferor Member and all
distributions of Available Cash thereafter attributable to such LLC Unit shall
be made to the transferee Member.

     E.   Notwithstanding anything to the contrary set forth herein, in addition
to any other restrictions on Transfer herein contained, in no event may any
Transfer or assignment of a Membership Interest by any Member (including any
Exchange or any other acquisition of LLC Units by the Company) be made:
          
          (a)  to any person or entity who lacks the legal right, power or
     capacity to own a Membership Interest;
          
          (b)  in violation of applicable law;
          
          (c)  if such Transfer would, in the opinion of counsel to the Company
     or the Managing Member, cause an increased tax liability to any other
     Member or Assignee as a result of the termination of the Company, in either
     case for federal or state income or franchise tax purposes (except as a
     result of the Exchange of all LLC Units held by all Members);
          
          (d)  if such Transfer could, in the opinion of legal counsel to the
     Company, cause the Company either (i) to cease to be classified as a
     partnership or (ii) to be classified as a publicly traded partnership
     treated as a corporation, in either case for federal or state income tax
     purposes (except as a result of the Exchange of all LLC Units held by all
     Members);
          
          (e)  if such Transfer would cause the Company to become, with respect
     to any employee benefit plan subject to Title I of ERISA, a "party-in-
     interest" (as defined in ERISA Section 3(14)) or a "disqualified person"
     (as defined in Code Section 4975(c));
          
          (f)  if such Transfer would, in the opinion of legal counsel to the
     Company, cause any portion of the assets of the Company to constitute
     assets of any employee benefit plan pursuant to Department of Labor
     Regulations Section 2510.2-101;
          
          (g)  if such Transfer causes the Company (as opposed to the Managing
     Member) to become a reporting company under the Exchange Act;
          
          (h)  if such Transfer subjects the Company to regulation under the
     Investment Company Act of 1940, the Investment Advisors Act of 1940 or
     ERISA, each as amended; or
          
          (i)  without the consent of the Managing Member, which may be given or
     withheld in its sole discretion, if such Transfer would result in the
     Company having more than 100 Members (including as Members those persons
     indirectly owning an interest in the Company through a partnership, limited
     liability company, S corporation or grantor trust (such entity, a "flow
     through entity"), but only if substantially all of the value of such
     person's interest in the flow through entity is attributable to the flow
     through entity's interest (direct or indirect) in the Company).

                              ADMISSION OF MEMBERS

     Section 12.1.  Admission of Successor Managing Member

     A successor to all of the Managing Member's Membership Interest pursuant to
Section 11.2 hereof who is proposed to be admitted as a successor Managing
Member shall be admitted to the Company as the Managing Member, effective
immediately upon such Transfer.  Any such successor shall carry on the business
of the Company without dissolution.  In each case, the admission shall be
subject to the successor Managing Member executing and delivering to the Company
an acceptance of all of the terms, conditions and applicable obligations of this
Agreement and such other documents or instruments as may be required to effect
the admission.

     Section 12.2.  Amendment of Agreement and Certificate

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

     Section 12.3.  Limitation on Admission of Substituted Members

     No Person shall be admitted to the Company as a Substituted Member if, in
the opinion of legal counsel for the Company, it would result in the Company
being treated as a corporation for federal income tax purposes or otherwise
cause the Company to become a reporting company under the Exchange Act.

                    DISSOLUTION, LIQUIDATION AND TERMINATION

     Section 13.1.  Dissolution

     The Company shall not be dissolved by the admission of Substituted Members
or by the admission of a successor Managing Member in accordance with the terms
of this Agreement.  Upon the withdrawal of the Managing Member, any successor
Managing Member shall continue the business of the Company without dissolution.
However, the Company shall dissolve, and its affairs shall be wound up, upon the
first to occur of any of the following (each a "Liquidating Event"):
     
     A.   the expiration of its term as provided in Section 2.5 hereof, in which
case the Managing Member shall have the right to purchase any outstanding Non-
Managing Member Units and any of the Company's Properties at their fair market
value at such time;
     
     B.   an event of withdrawal of the Managing Member, as defined in the Act
(other than an event of bankruptcy), unless, within 90 days after the
withdrawal, a Majority of Remaining Members agree in writing to continue the
business of the Company and to the appointment, effective as of the date of
withdrawal, of a substitute Managing Member;
     
     C.   subject to the provisions of Section 7.3.E hereof, an election to
dissolve the Company made by the Managing Member;
     
     D.   entry of a decree of judicial dissolution of the Company pursuant to
the provisions of the Act;
     
     E.   the sale of all or substantially all of the assets and properties of
the Company;

     F.   a final and non-appealable judgment is entered by a court of competent
jurisdiction ruling that the Managing Member is bankrupt or insolvent, or a
final and non-appealable order for relief is entered by a court with appropriate
jurisdiction against the Managing Member, in each case under any Bankruptcy Law
as now or hereafter in effect, unless prior to or within ninety days after the
entry of such order or judgment a Majority of Remaining Members Consent in
writing to continue the business of the Company and to the appointment,
effective as of a date prior to the date of such order or judgment, of a
substitute Managing Member;
     
     G.   the Incapacity of the Managing Member, unless prior to or within 90
days after such Incapacity a Majority of Remaining Members agree in writing to
continue the business of the Company and to the appointment, effective as of a
date prior to the date of such Incapacity, of a substitute Managing Member; or

     H.   the Exchange of all LLC Units (other than those held by the Managing
Member).

     Section 13.2.  Winding Up

     A.   Upon the occurrence of a Liquidating Event, the Company shall continue
solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets and satisfying the claims of its creditors and Members.
After the occurrence of a Liquidating Event, no Member shall take any action
that is inconsistent with, or not necessary to or appropriate for, the winding
up of the Company's business and affairs.  The Managing Member (or, in the event
that there is no remaining Managing Member, any Person elected by a Majority in
Interest of the Non-Managing Members (the Managing Member or such other Person
being referred to herein as the "Liquidator")) shall be responsible for
overseeing the winding up and dissolution of the Company and shall take full
account of the Company's liabilities and property, and the Company 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
Managing Member, include shares of stock in the Managing Member) shall be
applied and distributed in the following order:

          (1)  First, to the satisfaction of all of the Company's debts and
     liabilities to creditors other than the Members and their Assignees
     (whether by payment or the making of reasonable provision for payment
     thereof);
          
          (2)  Second, to the satisfaction of all of the Company's debts and
     liabilities to the Managing Member incurred with the consent of the Non-
     Managing Members (whether by payment or the making of reasonable provision
     for payment thereof), and to the satisfaction of all of the Company's debts
     and liabilities to the other Members and any Assignees with the consent of
     the Managing Member (whether by payment or the making of reasonable
     provision for payment thereof), pro rata based upon the amount of the debts
     and liabilities owing to the respective Managing Member, other Member and
     Assignee; and
          
          (3)  The balance, if any, to the Members in accordance with and
     proportion to their positive Capital Account balances, after giving effect
     to all contributions, distributions and allocations for all periods,
     including allocation made pursuant to Section 6.2.C to reflect Intended
     Liquidating Distributions.

The Managing Member 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 Company, but subject to the order of priorities
set forth therein, if prior to or upon dissolution of the Company the Liquidator
determines that an immediate sale of part or all of the Company's assets would
be impractical or would cause undue loss to the Members, the Liquidator may, in
its sole and absolute discretion, defer for a reasonable time the liquidation of
any assets except those necessary to satisfy liabilities of the Company
(including to those Members as creditors) and/or distribute to the Members, in
lieu of cash, as tenants in common and in accordance with the provisions of
Section 13.2.A hereof, undivided interests in such Company 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 Members, and shall be
subject to such conditions relating to the disposition and management of such
properties as the Liquidator deems reasonable and equitable and to any
agreements governing the operation of such properties at such time.  The
Liquidator shall determine the fair market value of any property distributed in
kind using such reasonable method of valuation as it may adopt.
     
     C.   In the event that the Company 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 Members 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 positive Capital Account balances.  If
any Member 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 Member shall have
no obligation to make any contribution to the capital of the Company with
respect to such deficit, and such deficit shall not be considered a debt owed to
the Company or to any other Person for any purpose whatsoever.  In the sole and
absolute discretion of the Managing Member or the Liquidator, a pro rata portion
of the distributions that would otherwise be made to the Members pursuant to
this Article 13 may be withheld or escrowed to provide a reasonable reserve for
Company liabilities (contingent or otherwise) and to reflect the unrealized
portion of any installment obligations owed to the Company, provided that such
withheld or escrowed amounts shall be distributed to the Members in the manner
and order of priority set forth in Section 13.2.A hereof as soon as practicable.

     Section 13.3.  Deemed Distribution and Recontribution

     Notwithstanding any other provision of this Article 13, in the event that
the Company is liquidated within the meaning of Regulations Section 1.704-
1(b) (2)(ii)(g), but no Liquidating Event has occurred, the Company's Property
shall not be liquidated, the Company's liabilities shall not be paid or
discharged and the Company's affairs shall not be wound up.  Instead, for
federal and state income tax purposes, the Company shall be deemed to have
distributed its assets in kind to the Members, who shall be deemed to have
assumed and taken such assets subject to all Company liabilities, all in
accordance with their respective Capital Accounts.  Immediately thereafter, the
Members shall be deemed to have recontributed the Company assets in kind to the
Company, which shall be deemed to have assumed and taken such assets subject to
all such liabilities.

     Section 13.4.  Rights of Members

     Except as otherwise provided in this Agreement, (a) each Member shall look
solely to the assets of the Company for the return of its Capital Contribution,
(b)  no Member shall have the right or power to demand or receive property other
than cash from the Company and (c) except as provided in this Agreement, no
Member shall have priority over any other Member 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 Members pursuant to Section 13.1
hereof, result in a dissolution of the Company, the Managing Member shall,
within 30 days thereafter, provide written notice thereof to each of the Members
and, in the Managing Member's sole and absolute discretion or as required by the
Act, to all other parties with whom the Company regularly conducts business (as
determined in the sole and absolute discretion of the Managing Member), and the
Managing Member may, or, if required by the Act, shall, publish notice thereof
in a newspaper of general circulation in each place in which the Company
regularly conduct business (as determined in the sole and absolute discretion of
the Managing Member).

     Section 13.6.  Cancellation of Certificate

     Upon the completion of the liquidation of the Company cash and property as
provided in Section 13.2 hereof, the Company shall be terminated and the
Certificate and all qualifications of the Company as a foreign limited liability
company in jurisdictions other than the State of Delaware shall be cancelled and
such other actions as may be necessary to terminate the Company 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 Company 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 Members during the period of liquidation.

     Section 13.8.  Liability of Liquidator
     The Liquidator shall be indemnified and held harmless by the Company from
and against any and all claims, liabilities, costs, damages, and causes of
action of any nature whatsoever arising out of or incidental to the Liquidator's
taking of any action authorized under or within the scope of this Agreement;
provided, however, that the Liquidator shall not be entitled to indemnification,
and shall not be held harmless, where the claim, demand, liability, cost, damage
or cause of action at issue arises out of (i) a matter entirely unrelated to the
Liquidator's action or conduct pursuant to the provisions of this Agreement or
(ii) the proven willful misconduct or gross negligence of the Liquidator.

     Section 14.1.  Procedures for Actions and Consents of Members

     The actions requiring consent or approval of Non-Managing Members pursuant
to this Agreement, including Section 7.3 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 consistent with the terms of this Agreement
may be proposed by the Managing Member or by a Majority in Interest of the Non-
Managing Members.  Following such proposal, the Managing Member shall submit any
proposed amendment to the Members.  The Managing Member shall seek the written
Consent of the Members on the proposed amendment or shall call a meeting to vote
thereon and to transact any other business that the Managing Member may deem
appropriate.  The affirmative vote or consent, as applicable, of the holders of
a majority of the outstanding LLC Units is required for the approval of a
proposed amendment.  For purposes of obtaining a written consent, the Managing
Member may require a response within a reasonable specified time, but not less
than 15 days, and failure to respond in such time period shall constitute a
consent that is consistent with the Managing Member'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 Members

     A.   Meetings of the Members may be called by the Managing Member and shall
be called upon the receipt by the Managing Member of a written request by a
Majority in Interest of the Non-Managing Members.  The call shall state the
nature of the business to be transacted.  Notice of any such meeting shall be
given to all Members not less than seven days nor more than 30 days prior to the
date of such meeting.  The meeting shall be held at the headquarters office of
the Managing Member or at such other location as may be designated by the
Managing Member.  Members may vote in person or by proxy at such meeting.
Whenever the vote or Consent of Members is permitted or required under this
Agreement, such vote or Consent may be given at a meeting of Members 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
Members may be taken without a meeting if a written consent setting forth the
action so taken is signed by Members holding a majority of the LLC 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 Members holding a majority
of the LLC Units (or such other percentage as is expressly required by this
Agreement).  Such consent shall be filed with the Managing Member.  An action so
taken shall be deemed to have been taken at a meeting held on the effective date
so certified.

     C.   Each Member may authorize any Person or Persons to act for it by proxy
on all matters in which a Member is entitled to participate, including waiving
notice of any meeting, or voting or participating at a meeting.  Every proxy
must be signed by the Member or its attorney-in-fact.  No proxy shall be valid
after the expiration of 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 Member executing it, such
revocation to be effective upon the Company's receipt of written notice of such
revocation from the Member executing such proxy.

     D.   Each meeting of Members shall be conducted by the Managing Member or
such other Person as the Managing Member may appoint pursuant to such rules for
the conduct of the meeting as the Managing Member or such other Person deems
appropriate in its sole and absolute discretion.  Without limitation, meetings
of Members may be conducted in the same manner as meetings of the Managing
Member's shareholders and may be held at the same time as, and as part of, the
meetings of the Managing Member's shareholders.

                                   ARTICLE 15.

     Section 15.1.  Addresses and Notice

     Any notice, demand, request or report required or permitted to be given or
made to a Member or Assignee under this Agreement shall be in writing and shall
be deemed given or made when delivered in person or when sent by first class
United States mail or by other means of written communication (including by
telecopy, facsimile, or commercial courier service) (i) in the case of a Member,
to that Member at the address set forth in Exhibit A or such other address of
which the Member shall notify the Managing Member in writing and (ii) in the
case of an Assignee, to the address of which such Assignee shall notify the
Managing Member in writing.

     Section 15.2.  Titles and Captions

     All article or section titles or captions in this Agreement are for

     Section 15.3.  Pronouns and Plurals

     Section 15.4.  Further Action

     Section 15.5.  Binding Effect

parties hereto and their heirs, executors, administrators, successors, legal
representatives and permitted assigns.
     
     Section 15.6.  Creditors

     Other than as expressly set forth herein with respect to Indemnitees, none
of the provisions of this Agreement shall be for the benefit of, or shall be
enforceable by, any creditor of the Company.

     Section 15.7.  Waiver

     No failure by any party to insist upon the strict performance of any
covenant, duty, agreement or condition of this Agreement or to exercise any
right or remedy consequent upon a breach thereof shall constitute waiver of any
such breach or any other covenant, duty, agreement or condition.

     Section 15.8.  Counterparts

     This Agreement may be executed in counterparts, all of which together shall
constitute one agreement binding on all the parties hereto, notwithstanding that
all such parties are not signatories to the original or the same counterpart.

     Section 15.9.  Applicable Law

     This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Delaware, without regard to the principles
of conflicts of law.  In the event of a conflict between any provision of this
Agreement and any non-mandatory provision of the Act, the provisions of this
Agreement shall control and take precedence.

     Section 15.10. Entire Agreement

     This Agreement, the Contribution Agreement and the other agreements
executed on the Effective Date as provided in the Contribution Agreement contain
all of the understandings and agreements between and among the Members with
respect to the subject matter of this Agreement and the rights, interests and
obligations of the Members with respect to the Company.

     Section 15.11  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 15.12. Limitation to Preserve REIT Status
Notwithstanding anything else to the contrary in this Agreement, to the extent
that any amount paid or credited to the Managing Member or its officers,
directors, employees or agents pursuant to Section 7.7 would constitute gross
income to the Managing Member for purposes of Sections 856(c)(2) or 856(c)(3) of
the Code (a "Managing Member Payment") then, notwithstanding any other provision
of this Agreement, the amount of such Managing Member Payments for any fiscal
year shall not exceed the lesser of:

          (i)  an amount equal to the excess, if any, of (a) 4.17% of the
     Managing Member's total gross income (but not including the amount of any
     Managing Member Payments) for the fiscal year which is described in
     subsections (a) through (H) of Section 856(c)(2) of the Code over (b)  the
     amount of gross income (within the meaning of Section 856(c)(2) of the
     Code) derived by the Managing Member from sources other than those
     described in subsections (a) through (H) of Section 856(c)(2) of the Code
     (but not including the amount of any Managing Member Payments); or
          
          (ii) an amount equal to the excess, if any, of (a) 25% of the Managing
     Member's total gross income (but not including the amount of any Managing
     Member Payments) for the fiscal year which is described in subsections
     (a) through (i) of Section 856(c)(3) of the Code over (b)  the amount of
     gross income (within the meaning of Section 856(c)(3) of the Code) derived
     by the Managing Member from sources other than those described in
     subsections (a) through (i) of Section 856(c)(3) of the Code (but not
     including the amount of any Managing Member Payments);

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

     Section 15.13. No Partition

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

     Section 15.14. Non-Managing Member Representative
     
     A.   All actions taken by the Non-Managing Member Representative pursuant
to those provisions of this Agreement which authorize the Non-Managing Member
Representative to so act shall be binding upon all Non-Managing Members as if
they had individually taken such action and each Non-Managing Member, by
entering into or agreeing to be bound by the provisions of this Agreement,
authorize the Non-Managing Member Representative to take such actions on his,
her or its behalf and agree that the actions so taken shall be binding upon him,
her or it to the same extent as if he, she or it had taken the action directly.
     
     B.   The holders of a majority of the outstanding Non-Managing Members
Units shall be entitled to replace the Non-Managing Member Representative by
delivering to the Managing Member a written notice signed by the holders of a
majority of the outstanding Non-Managing Members Units stating (i) that the
notice is being provided to the Managing Member pursuant to this Section
15.14.B, (ii) that the Members signing the notice own of record on the books of
the Company a majority of the outstanding Non-Managing Members Units, (iii) that
the Members signing the notice desire to replace the person then serving as the
Non-Managing Member Representative with the person named in the notice, and
(iv) specifying the date on which the appointment of the named individual to
replace the then serving Non-Managing Member Representative shall be effective
(which shall be a date not earlier than the fourteenth day after the date on
which the notice shall have been delivered to the Managing Member).  The
appointment of the new Non-Managing Member Representative specified in the
notice shall be effective on the date specified in the notice and upon
effectiveness, the individual previously serving as the Non-Managing Member
Representative shall cease to be entitled to act in that capacity under this
Agreement.
