            cost recovery deductions taken into account in computing such
            taxable income or loss, there shall be taken into account

to the Company in proportion to their respective Percentage Interests.

            6.4   Except as expressly provided in this Article 6, no Member
shall be required to make any capital contributions or loans to the Company and
no Member shall make any capital contributions or loans to the Company without
the consent of the other Member.

      7.    Income and Losses; Distribution of Available Net Income.

            7.1   A separate "Capital Account" shall be maintained for each
Member. Each Member's Capital Account shall be credited with the amount of such
Member's capital contributions made in cash and the fair market value (net of
liabilities assumed or taken subject to) of all property contributed by such
Member and such Member's allocated share of Net Profit, income and gain of the
Company. Each Member's Capital Account shall be debited with the amount of any
cash distributions to such Member and the fair market value (net of liabilities
assumed or taken subject to) of all property distributed in kind to such Member
and such Member's allocated share of Net Loss of the Company.

            7.2   From and after the date of this Agreement, all Net Profit and
all Net Loss of the Company for each year or fraction thereof (determined after
taking into account any allocation for


                                       6
   7
such period under Section 7.3) shall be credited to the Capital Accounts of the
Members in proportion to their respective Percentage Interests.

            7.3   Special Allocations.

                  7.3.1 Except as otherwise provided in Section 7.3.2, all items
of Company income, gain, deduction and loss shall be allocated among the Members
in the same proportion as they share in the Net Profit and Net Loss to which
such items relate. Any credits against income tax shall be allocated in
accordance with the Members' Percentage Interests.

                  7.3.2 Income, gain, loss or deductions of the Company shall,
solely for income tax purposes, be allocated among the Members in accordance
with Section 704(c) of the Code and the Treasury Regulations promulgated
thereunder, so as to take account of any difference between the adjusted basis
of the assets of the Company and their respective Gross Asset Values in
accordance with the traditional method set forth in Section 1.704-3 (b) of the
Treasury Regulations.

                  7.3.3 Notwithstanding any other provision of this Article 7,
if there is a net decrease in Company Minimum Gain during any year, each Member
shall be specially allocated items of income and gain for such year (and, if
necessary, subsequent years) in an amount equal to the portion of such Member's
share of the net decrease in Company Minimum Gain, determined in accordance with
Section 1.704-2(g) of the Treasury Regulations. 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 Section 1.704-2(f)(6) of the Treasury
Regulations. Thus Section 7.3.3 is intended to comply with the minimum gain
chargeback requirement in Section 1.704-2(f) of the Treasury Regulations and
shall be interpreted consistently therewith.

                  7.3.4 Notwithstanding any other provisions of this Article 7,
if there is a net decrease in Member Minimum Gain attributable to a Member
Nonrecourse Debt during any year,


                                       7
   8
each Member who has a share of the Member Minimum Gain attributable to such
Member Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(5) of
the Treasury Regulations, shall be specially allocated items of income and gain
for such year (and, if necessary, subsequent years) in an amount equal to the
portion of such Member's share of the net decrease in Member Minimum Gain
attributable to such Member Nonrecourse Debt, determined in accordance with
Section 1.704-2(i)(4) of the Treasury Regulations. 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 Section 1.704-2(i)(4) of the Treasury
Regulations. This Section 7.3.4 is intended to comply with the minimum gain
chargeback requirement in Section 1.704-2(i) of the Treasury Regulations and
shall be interpreted consistently therewith.

                  7.3.5 Nonrecourse Deductions for any year shall be allocated
as Net Loss pursuant to Section 7.2.

                  7.3.6 Any Member Nonrecourse Deductions for any year shall be
specially allocated to the Member 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 Section 1.7042(i)(1) of the
Treasury Regulations.

                  7.3.7 Notwithstanding any other provision of this Article 7,
no Member shall be allocated in any year of the Company any Net Loss to the
extent such allocation would cause or increase a deficit balance in such
Member's Adjusted Capital Account, taking into account all other allocations to
be made for such year pursuant to this Article 7 and the reasonably expected
adjustments, allocations and distributions described in Section
1.704-1(b)(2)(ii)(d) of the Treasury Regulations. Any such Net Loss that would
be allocated to a Member (the "Deficit Member") shall instead be allocated to
the other Member. Moreover, if a Deficit Member unexpectedly receives an
adjustment, allocation or distribution described in Section 1.704-1(b)(2)(ii)(d)
of the Treasury Regulations which creates


                                       8
   9
or increases a deficit balance in such Member's Adjusted Capital Account
(computed after all other allocations to be made for such year pursuant to this
Article 7 have been tentatively made as if this Section 7.3.7 were not in this
Agreement), such Deficit Member shall be allocated items of income and gain in
an amount equal to such deficit balance. This Section 7.3.7 is intended to
comply with the qualified income offset requirement of Section
1.704-1(b)(2)(ii)(d) of the Treasury Regulations and shall be interpreted
consistently therewith.

                  7.3.8 The allocations set forth in Sections 7.3.3 through
7.3.7 (the "Regulatory Allocations") shall be taken into account in allocating
items of income, gain, loss and deduction among the Members so that, to the
extent possible, 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.

            7.4   Distributions. All distributions of Company cash and other
property shall be made to the Members in proportion to their respective
Percentage Interests; provided, however, that the provisions of this Section 7.4
shall not apply upon the liquidation of the Company or upon the sale of all or
substantially all of the Company's assets, it being understood that in such
circumstances the provisions of Section 13.4 shall apply.

      8.    Tax Matters. Federal, state and local income tax returns of the
Company shall be prepared and filed, or caused to be prepared and filed, by
CapStar. CapStar shall at all times be the "tax matters partner" of the Company
for purposes of Section 6231(a)(7) of the Code.

      9.    Management and Rights, Duties and Obligations of the Members.

            9.1   The management and control of the Company's business shall be
exercised, and all decisions to be made by the Company shall in each case be
made, by CapStar. CapStar shall have the sole right to bind, or otherwise act on
behalf of, the Company. Without limiting the


                                       9
   10
foregoing, CapStar shall have the right, without the consent or approval of
EquiStar, to acquire, mortgage or otherwise encumber, and sell or otherwise
dispose of the Property or any portion thereof.

            9.2   Except as otherwise expressly provided in this Agreement, no
Member shall have the right to resign from the Company or to demand the return
of all or any part of its contribution to the capital of the Company until the
Company has been dissolved and terminated, and then only to the extent provided
in this Agreement, nor shall any Member have the right to demand or receive
property other than cash in return for its contribution.

      10.   Transfer of Members' Interests. No Member shall sell, assign,
transfer or otherwise dispose of, or mortgage, hypothecate, pledge or otherwise
encumber, or permit or suffer any encumbrance of, all or any part of its
interest in the Company, or any interest therein; provided, however, that each
Member may pledge its interest in the Company to any lender making a loan
secured, in whole or in part, by a mortgage or deed of trust on the Property.

      11.   Resignation, Expulsion or Bankruptcy of a Member. In the event of
the resignation, expulsion or bankruptcy of any Member, the Company shall
thereupon be dissolved and terminated and the Members shall cause a Certificate
of Cancellation in the form required by the Act to be filed with the Secretary
of State of Delaware when the Company is dissolved.

      12.   Termination of the Company. Upon the voluntary termination of the
Company upon the consent of the Members, the sale or other transfer of all or
substantially all of the Company's assets or any other termination of the
Company in accordance with the provisions of this Agreement, the Company shall
wind up its affairs and shall then be liquidated as provided in Article 13.

      13.   Gain, Loss and Distribution on Liquidation. Upon any termination of
the Company each of the following shall be accomplished:


                                       10
   11
            13.1  The Members shall cause to be prepared a statement setting
      forth the assets and liabilities of the Company as of the date of such
      termination, and such statement shall be furnished to each Member.

            13.2  The property and assets of the Company, if any, shall be
      liquidated as promptly as possible, but in an orderly and businesslike
      manner so as not to involve undue sacrifice.

            13.3  Any Net Profit or Net Loss realized by the Company upon the
      sale or other disposition of the property and assets of the Company shall
      be credited or charged to the capital accounts of the Members pursuant to
      Section 7.2 or 7.3, as applicable.

            13.4  The proceeds of sale and all other assets of the Company shall
      be paid and distributed as follows and in the following order of priority:

                  13.4.1 to the payment of the debts and liabilities of the
            Company and the expenses of liquidation;

                  13.4.2 to the setting up of any reserves which CapStar
            determines are reasonably necessary for any contingent or unforeseen
            liabilities or obligations of the Company or the Members arising out
            of, or in connection with, the Company; and

                  13.4.3 to the Members in proportion to their respective
            Capital Account balances.

      14.   Further Assurances; Consents and Approvals. Each party to this

Cross-Collateralization Agreements, the Company shall at all times conduct its
business and operations in accordance with the following provisions so as to
maintain itself as a single purpose entity:

                  15.1.1 The Company will not assume liability for the debts of

                  15.1.2 None of the liabilities of the Company shall be paid
