PROVIDED, FURTHER, that Keystone shall not be required to give a Shortfall
Notice for the third or subsequent Shortfall during any twelve (12) month
period.

          (c)     The Company shall have the right to request in writing, within
three (3) business days of Keystone's sending of the Shortfall Notice, thirty
(30) days from the date that the Shortfall Notice was sent (the "FIRST EXTENSION
PERIOD") to distribute the Preferred Return and the Shortfall Distribution to
Keystone and Keystone Investor PROVIDED, HOWEVER, that the Company may exercise
the right to a First Extension Period not more than twice during any twelve (12)
month period. Such response shall set forth the reasons for the occurrence of
the Shortfall and the actions that the Company shall undertake to ensure that
all outstanding Preferred Return and Shortfall Distribution amounts are
distributed to Keystone and Keystone Investor by the expiration of the First
Extension Period. If, on the expiration date of the First Extension Period, the
Company shall have failed to distribute all outstanding Preferred Return and
Shortfall Distribution amounts, the Company shall have the right to a further
extension, effective on such expiration date, by requesting in writing, a
fifteen (15) day extension to the First Extension Period (the

                                      - 9 -

Shortfall Distribution amounts shall be distributed to Keystone and Keystone
Investor by the expiration of the Second Extension Period.

contribute to the Company as a Capital Contribution all sums refunded to
Landmark by the State of New York with respect to the QEZE Credit for Real
Property Taxes ("QEZE REFUND") within sixty (60) days of Landmark's receipt of
the QEZE Refund. Landmark guarantees to the Company and the Members the payment
of all Eligible Real Property Taxes of the Company for which a QEZE Credit for
Real Property Taxes is received ("LANDMARK GUARANTEE"). The Landmark Guarantee
is for the benefit of the Company and the Members and not for the benefit of any
third party. Neither Landmark nor the Company shall be required to contribute to
the other any QEZE Refund to the extent that Landmark or the Company, as the
case may be, has been required to make payment on the Landmark Guarantee. In the
event, for any reason, the allocation set forth in Section 2.1(c) of Exhibit D

Member shall contribute its QEZE Refund to the Company as a Capital Contribution
within sixty (60) days of the Member's receipt of the QEZE Refund.

          (e)     None of Landmark, TSL, Keystone or Keystone Investor shall

     unsatisfied condition shall have been waived in writing by the Company.

Member (a "CAPITAL ACCOUNT"). The Capital Accounts of the Members following the
Closing and related events shall be as set forth on EXHIBIT E attached hereto.
Upon a valid transfer of a Member's interest in the Company ("MEMBERSHIP
INTEREST") in accordance with ARTICLE V hereof, such Member's Capital Account
shall carry over to the new owner. Subject to the preceding sentence, each
Member's Capital Account shall be increased by:

          (a)     the amount of money contributed by it to the Company,

          (b)     the fair market value of any property contributed by it to the

Company (net of liabilities secured by such distributed property that such
Member is considered to assume or take subject to under Section 752 of the
Code), and

          (c)     allocations of Loss and other items of book loss, expense and
deduction.

          The foregoing definitions and provisions of EXHIBIT D annexed hereto

Section 704(b) of the Code and the Treasury Regulations thereunder and shall be
interpreted and applied in a manner consistent therewith.

          Except as otherwise provided in the Act, the debts, obligations and
liabilities of the Company (whether arising in contract, tort or otherwise)
shall be solely the debts, obligations and liabilities of the Company, and no

be liable or shall be obligated personally for any such debt, obligation or
liability of the Company. No individual trustee, officer, director, shareholder,

Member, in its individual capacity as such, shall have any personal liability
for the performance of any obligation of such Member under this Agreement.

     2.8  PAYMENTS TO MEMBERS

          Except as specified in this Agreement or pursuant to a transaction
permitted by SECTION 3.7, no Member and no Affiliate of a Member is entitled to

     and all liabilities, including contingent liabilities that Keystone may
     have incurred during such time that it served as Manager, pursuant to (Z)
     below, then Landmark shall not have the right to be reinstated as Manager,
     (Y) TSL and Landmark shall reimburse Keystone for any and all third-party
     expenses it incurs in connection with the removal of Landmark, Keystone
     becoming replacement manager and/or the reinstatement of Landmark as

     Manager, (Z) TSL and Landmark shall take all actions necessary to relieve

     Properties;

                  (iv)    any contract for services that cannot be cancelled

Property of an amount equal to or less than the outstanding balance of the debt

commercially reasonable efforts to have the loan documents relating to such new
indebtedness provide that the exercise by Keystone of its rights and remedies
under SECTIONS 3.1(c) and 4.2(c) shall not cause a default or an event of
default or constitute a transfer of interests permitting lender to accelerate
such loan PROVIDED, that if such refinancing is more than 90 days prior to the
maturity of the indebtedness existing on such Property, the interest rate on the

                                     - 13 -

or to the Company for any loss resulting from errors made by any of the
Indemnified Parties in good faith or from such acts or omissions, whether or not

amounts in the event that it is determined by a court of competent jurisdiction,
or as a result of the settlement of such matter, that the Indemnified Party was
not entitled to such indemnity or the Indemnified party committed fraud, willful
misconduct, or gross negligence. If any Indemnified Party shall be required to
repay to the Company any sums it has received pursuant to this SECTION 3.6 and
shall have failed to make such repayment within sixty (60) days after receiving
written demand therefor from the Company, then the Company shall have the right
to offset any such unrepaid amount against all future sums otherwise
distributable to such Member related to such Indemnified Party until the Company
has received such repayment in full and any amounts so offset against future
distributions shall be deemed to have been distributed to such Member under this
Agreement.

          (e)     The Company's obligations to indemnify, defend and save
harmless under this SECTION 3.6 shall not obligate, or impose personal liability
on, any of the Members or any of their directors, shareholders, investment

     unpaid Preferred Return, and any unpaid Shortfall and Shortfall
     Distribution has been paid in full;

                  (ii)    SECOND, to Keystone and Keystone Investor, PRO RATA in

          (c)     Notwithstanding anything to the contrary in this Agreement, in

payable (the date on which such Shortfall and Shortfall Distribution becomes due
and payable, the "SHORTFALL DATE") and has not been paid in full within ninety
(90) days after the Shortfall Date, or (ii) Landmark has defaulted on the
Landmark Guarantee, then

                                     - 18 -
<Page>

all distributions under SECTION 4.2 shall be payable to Keystone and Keystone
Investor, and Landmark and TSL shall not be entitled to any further
distributions hereunder.

          (d)     Notwithstanding anything to the contrary in this Agreement, on
or after December 1, 2008, Keystone shall have the right to cause the Company to
distribute Cash from Operations and Cash from Sale, Financing or Refinancing to
Keystone and Keystone Investor (including the right to require the Company to
sell, finance or refinance any Property or Properties) in such amount as
necessary to reduce the Keystone Invested Capital to zero.

          (e)     Notwithstanding anything to the contrary in this Agreement, in
the event that any Special Indemnity Damages shall be due and payable to the
Company, the Company shall have the right to require such damages be retained by
the Company to the extent of Cash from Operations or Cash from Sale, Financing
or Refinancing in priority to any payments due to Keystone and Keystone Investor
under this SECTION 4.2 until such Special Indemnity Damages have been fully
repaid and such payment shall be considered to be a distribution to Keystone and
a payment of the Special Indemnity by Keystone to the Company.

          (f)     Notwithstanding anything to the contrary in this Agreement,
until the respective expirations of the Delmar Indemnity and the Hartford
Indemnity, for such periods, if any, that a Delmar Lease Payment Default or a
Hartford Lease Payment Default exists and remains uncured, the Company shall
have the right to retain amounts equal to the Delmar Lease Deficit and/or
Hartford Lease Deficit, as the case may be, otherwise distributable to Keystone
under SECTION 4.2(b)(i) pursuant to the terms of the Delmar Indemnity and the
Hartford Indemnity, respectively. In the event that the Company receives any
unpaid Delmar Rent or Hartford Rent, as the case may be, by or on behalf of
Delmar or Hartford, respectively, then the Company shall immediately distribute
to Keystone (i) with respect to the portion of such rent attributable to the
period commencing on the first date Delmar Rent or Hartford Rent, as the case
may be, is not paid, until the end of the twelfth month thereafter, fifty
percent (50%) of such amount received, (ii) with respect to the portion of such
rent attributable to the period commencing on the first day of the thirteenth
month after the first date Delmar Rent or Hartford Rent, as the case may be, is
not paid, until the end of the twelfth month thereafter, seventy-five percent
(75%) of such amount received and (iii) with respect to the portion of such rent
attributable to the period commencing on the first day of the twenty-fifth month
after the first date Delmar Rent or Hartford Rent, as the case may be, is not
paid, one hundred percent (100%) of such amount received. Upon the receipt of a
final court order or judgment rendered by a court of competent jurisdiction on a
Claim made by Delmar or Hartford, as the case may be, in an amount less than the
aggregate amount of the unpaid Delmar Rent or Hartford Rent, as the case may be,
then Keystone shall be obligated to pay any shortfall in respect of such Delmar
Rent or Hartford Rent attributable to such Claim (the "RENT DEFICIT AMOUNT"), in
the manner prescribed by Section 3(a) of the Delmar Indemnity or Hartford
Indemnity, as the case may be, PROVIDED, HOWEVER, that if Keystone fails to pay
the Rent Deficit Amount, within the fifteen (15) day period required by the
Delmar Indemnity or the Hartford Indemnity, as the case may be, then the Company
may immediately take an offset for the Rent Deficit Amount from retained
distributions and shall have the right to offset from future distributions
required to be paid to Keystone pursuant to SECTION 4.2(b)(i) hereof for any
deficiency between the retained distribution offset by the Company and the Rent
Deficit Amount. To the extent the Rent Deficit Amount for such Claim is less
than the retained distribution, the Company shall offset the Rent Deficit Amount
from retained distribution and shall pay to Keystone within the same fifteen
(15) day period any retained distributions remaining after such offset. In the
event that a final court order or judgment finds both Keystone and one or more
of the other persons indemnified under the Delmar Indemnity or the Hartford
Indemnity, as the case may be, responsible for liability under the action or
proceeding but does not allocate liability between the parties, then prior to
the date that the Rent Deficit Amount with respect to the Delmar Rent or the
Hartford Rent, as the case may be, is payable and prior to the effectiveness of
any offset rights, the parties shall mutually submit such issue to arbitration
to be

                                     - 19 -
<Page>

finally determined by arbitration in the City of New York in accordance with the
rules and regulations then obtaining of the American Arbitration Association or
its successor; any such determination shall be final and binding upon the
parties, whether or not a judgment shall be entered in any court. The parties
may, at their own expense, be represented by counsel and employ expert witnesses
in any such arbitration, and the parties shall share all other expenses and fees
of any such arbitration. Notwithstanding the foregoing, subject to certain
conditions set forth in the Hartford Indemnity, the Company shall also have the
right to suspend the retention of distributions from Keystone pursuant to the
terms of Section 2(c) of the Hartford Indemnity and to reinstate the retention
of distributions pursuant to the terms of Section 3(b) of the Hartford
Indemnity.

          (g)     Notwithstanding anything to the contrary in this Agreement,
the Company shall have the right to retain amounts equal to the M&T Amortization
Difference on scheduled loan payments otherwise distributable to Keystone and
Keystone Investor under SECTION 4.2(b)(i), PROVIDED THAT any right that the
Company may have to retain amounts equal to the M&T Amortization Difference for
the Delmar Property or the Columbia Property, as the case may be, shall
terminate upon the occurrence of (i) the sale, by the Company, of the Delmar
Property or the Columbia Property, as the case may be, (ii) the payment in full
of the obligations under the New M&T Loans relating to such Property, or (iii)
the sale, by the Company, of any Property at a price that is greater than the
minimum sales price for such Property as listed on EXHIBIT F hereto and,
PROVIDED FURTHER, notwithstanding anything to the contrary in this Agreement,
(x) upon the occurrence of (i) or (ii) above, all amounts retained by the
Company in respect M&T Amortization Difference for such Property shall be
immediately returned to Keystone and (y) upon the occurrence of (iii) above,
fifteen percent (15%) of all amounts greater than the minimum sales price for
such Property as listed on EXHIBIT F hereto received by the Company shall be
immediately distributed to Keystone.
