Item 3.  Source and Amount of Funds or Other Consideration.
         -------------------------------------------------

         The total amount of funds required by WXI/McN Realty in connection with
the   consummation  of  the  transaction,   assuming  all  McNeil   Partnerships
participate in the transaction,  is estimated to be approximately  $644,439,803.
Such amount includes the amounts estimated to be required to pay the cash merger
consideration  to the  limited  partners  of the McNeil  Partnerships,  to repay
certain  mortgage debt of the McNeil  Partnerships  and certain  prepayment fees
payable in connection therewith,  to pay the amount of the shortfall, if any, of
the amount of cash on hand held by each of the participating McNeil Partnerships
at the time of the closing from the  estimated  special  distribution  that each
participating  McNeil  Partnership is expected to make; and to pay certain other
expenses  expected to be incurred in connection  with the  transaction and other
amounts  that  WXI/McN  Realty is required  to pay  pursuant to the terms of the
Master  Agreement.  Such amounts would vary in the event that one or more of the
McNeil  Partnerships are not participating  McNeil  Partnerships or in the event
that the amount of special  distributions,  expenses or other  amounts vary from
the estimated amounts included above.

         It is  expected  that  the  transactions  contemplated  by  the  Master
Agreement  and  described  in Item 4 would be funded  through a  combination  of
equity  and debt  financing.  Pursuant  to the  terms

of the limited  liability  company agreement of WXI/McN that will be executed in
connection  with the  closing  of the  transactions  contemplated  by the Master
Agreement (the "WXI/McN LLC  Agreement"),  the sole managing  member of WXI/McN,
which is 99% owned by  Whitehall,  has agreed to contribute to WXI/McN an amount
in cash equal to the amounts  described  above,  and pursuant to the terms of an
equity  commitment  letter from  Whitehall to WXI/McN,  Whitehall  has agreed to
provide,  or to cause one or more of its  affiliates to provide,  a cash capital
contribution to WXI/McN Realty in an amount equal to such amounts.  The funds to
be used by Whitehall to meet its funding  commitments  are expected to come from
capital contributions from the partners in Whitehall.  The WXI/McN LLC Agreement
also provides that McNeil Partners will,  immediately  prior to the consummation
of the transactions  contemplated by the Master  Agreement,  contribute  certain
assets,  including  certain  management  assets currently held by McREMI and the
general  partnership  interests  in the McNeil  Partnerships,  to WXI/McN or its
affiliates in exchange for membership units in WXI/McN. It is also expected that
WXI/McN will obtain third party mortgage or other  financing that will provide a
portion of the amount of required funds described  above,  although  WXI/McN has
not, as of the date of this  Schedule  13D,  entered  into any  agreements  with
respect to any such financing.

LLC Agreement are subject to a number of terms and conditions set forth therein,
including,  among others, the execution of mutually acceptable documentation and
the  satisfaction of the conditions set forth in the Master  Agreement.

               Section 1.3 Allocation of the Aggregate Consideration.

               (a) As promptly as practicable following the date hereof and
prior to the Effective Time, Sellers shall cause Stanger to allocate the
Aggregate Consideration between (i) certain assets of McREMI, taken as a whole
(the "Partial McREMI Allocated Value"), and (ii) all of the McNeil Partnerships,
taken as a whole, including certain other assets of MPLP (assuming the
contributions in Section 2.2 hereof have been consummated)(the matters in this
clause (ii), collectively, the "Total Allocated Partnership Value").

               (b) Upon the completion of the allocation described in Section
1.3(a) hereof, the Total Allocated Partnership Value shall be allocated among
the McNeil Partnerships (the portion of the Total Allocated Partnership Value
attributable to a McNeil Partnership pursuant to this Section 1.3(b), the "Per
Partnership Allocated Value" for such McNeil Partnership), by multiplying, with
respect to each McNeil Partnership (i) the Total Allocated Partnership Value by
(ii) the Partnership Percentage of such McNeil Partnership.

               (c) As promptly as practicable following the completion of the
allocations described in Sections 1.3(a) and 1.3(b) hereof and assuming that the
contributions described in Section 2.2 hereof have been consummated, Sellers
shall cause Stanger to allocate the Net Per Partnership Allocated Value of each
McNeil Partnership among (i) the GP Interests, taken as a whole, in such McNeil
Partnership and certain other assets of MPLP (for each McNeil Partnership, the
"MPLP Allocation Amount" for such McNeil Partnership) and (ii) each class of LP
Interests, taken as a whole, in such McNeil Partnership (for each class of LP
Interests in each McNeil Partnership, the "LP Allocation Amount" for such class
of LP Interests in such McNeil Partnership). For purposes of this Agreement,
"Net Per Partnership Allocated Value" of a McNeil Partnership means an amount
equal to the difference determined by subtracting (i) the aggregate outstanding
principal amount, determined as of the Stanger Determination Date, of all
Existing Loans of such McNeil



                                       8

Partnership from (ii) the Per Partnership Allocated Value of such McNeil
Partnership.

               (d) As promptly as practicable following the completion of the
allocations described in Sections 1.3(a), 1.3(b) and 1.3(c) hereof, (i) Sellers
shall cause Stanger to render a per unit allocation of the LP Allocation Amount
for each LP Interest for each class of LP Interests in each McNeil Partnership
(the "Per Unit Allocation Amount" for such LP Interest) and (ii) Sellers shall
cause Stanger to allocate the MPLP Allocation Amount for each McNeil Partnership
among (1) certain McREMI Assets (the "Second McREMI Allocated Value") and (2)
the GP Interests, taken as a whole, in such McNeil Partnership (the "GP
Allocation Amount" for such McNeil Partnership). For purposes of this Agreement,
the "Total McREMI Allocated Value" shall equal the sum of the Partial McREMI
Allocated Value and the aggregate of the Second McREMI Allocated Values.

               (e) Each party to this Agreement agrees to be unconditionally and
irrevocably bound by the Allocations, except for manifest error in the
allocation described in Section 1.3(d) hereof.

               Section 1.4 Additional Consideration. Immediately prior to the
Effective Time, in accordance with Sections 2.3 and 7.9(b) hereof and Section
6.1 of the LLC Agreement, the Company shall issue to MPLP (or another designee
of the Contributing Partners) Company Interests, and MPLP (or another designee
of the Contributing Partners) shall receive credit for a capital contribution to
the Company in an amount equal to the sum of (A) the McNeil Cash Contribution
(if any), (B) the Capitalized McNeil Expenses and (C) the Additional McNeil
Contribution (if any). Such Company Interests shall upon issuance be duly
authorized, validly issued, fully paid and nonassessable and free and clear of
all Liens (except as provided in the Indemnification Agreement, the LLC
Agreement or the DLLCA), and shall be issued to MPLP (or another designee of the
Contributing Partners). Nothing in this Section 1.4 shall offset, or affect in
any manner, the Company Interests being issued to MPLP (or another designee of
the Contributing Partners) pursuant to Section 1.1 hereof.

               Section 1.5 Indebtedness.

               (a) Schedule 1.5 of the Seller Disclosure Letter sets forth all
of the indebtedness of each of the McNeil Partnerships, which indebtedness is
secured by the McNeil Partnership Properties (the "Existing Loans"), the
outstanding principal balance thereof, all accrued and unpaid interest thereon,
the interest rate thereof and the remaining term thereof, in each case, as of
the date specified on such Schedule 1.5.

               (b) Notwithstanding anything to the contrary in this Agreement,
the Company shall repay at the Effective Time (including all accrued but unpaid
interest thereon through to the Effective Time) all of the Existing Loans set
forth on Annex A hereto which are secured by McNeil Partnership Properties of
the Participating McNeil Partnerships (the "Tranche A Terminated Loans").
Notwithstanding anything to the contrary in this Agreement, the Company shall
pay at the Effective Time all Prepayment Fees relating to the Tranche A
Terminated Loans. For purposes of this Agreement, the term "Prepayment Fees"
means any fees, costs and premiums charged by the lender of an Existing Loan in
connection with its prepayment.

               (c) Notwithstanding anything to the contrary in this Agreement,
the Company shall repay at the Effective Time (including all accrued but unpaid
interest thereon through to the Effective Time) all of the Existing Loans set
forth on Annex B hereto which are secured by McNeil Partnership Properties of
the Participating McNeil Partnerships (the "Tranche B Terminated Loans" and,
together with the Tranche A Terminated Loans, the "Terminated Loans").
Notwithstanding anything to the contrary in this Agreement, each Participating
McNeil Partnership shall pay at the Effective Time all Prepayment Fees relating
to the Tranche B Terminated Loans secured by McNeil Partnership Properties of
such Participating McNeil Partnership.

               (d) Other than the Terminated Loans, all Existing Loans
outstanding immediately prior to the Effective Time shall continue to remain
outstanding at and



                                       10

after the Effective Time until their expiration or prepayment (all Existing
Loans other than the Terminated Loans, the "Non-Terminated Loans").

               (e) Notwithstanding anything to the contrary in this Agreement,
each Participating McNeil Partnership shall pay at the Effective Time all
Assumption Fees relating to those Non-Terminated Loans set forth on Annex C
hereto which are secured by McNeil Partnership Properties of such Participating
McNeil Partnership in an amount with respect to each such Non-Terminated Loan
(the aggregate amount of all Assumption Fees payable in respect of all such
Non-Terminated Loans, the "Paid Assumption Fees") equal to the lesser of (1) the
Assumption Fees for such Non-Terminated Loan and (2) the Prepayment Fees for
such Non-Terminated Loan; provided, however, that the Company shall pay a
portion of such Assumption Fees equal to the lesser of (1) one-half of the Paid
Assumption Fees and (2) two hundred fifty thousand dollars ($250,000). For
purposes of this Agreement, the term "Assumption Fees" means any fees, costs and

Sellers and the Company agree in writing, the method of effecting the business
combination between any one or more Sellers and the Company may be changed, and
each party hereto shall cooperate in such efforts, including to provide for
different forms of merger; provided, however, that no such change shall (i)
alter or change the amount or kind of consideration to be received by holders of
LP Interests and holders of GP Interests in the Participating McNeil
Partnerships, (ii) adversely affect the proposed tax treatment to holders of LP
Interests and holders of GP Interests in the Participating McNeil Partnerships
or (iii) materially delay the

consummation of any of the Mergers or the other transactions contemplated by
this Agreement.

               Section 2.4 Pre-Closing Distribution.

               (a) No less than ten (10) business days prior to the estimated
Closing Date, MPLP shall cause to be prepared and delivered to the Company an
unaudited balance sheet for each McNeil Partnership as of the last day (which
shall be a date within forty-five (45) days of the estimated Closing Date) of
the most recently completed fiscal month for which an unaudited balance sheet
for such McNeil Partnership is available (each, a "Preliminary Pre-Closing
Balance Sheet"). The Preliminary Pre-Closing Balance Sheet for each McNeil
Partnership shall be prepared in accordance with generally accepted accounting
principles ("GAAP") applied consistently with past practice. The Preliminary
Pre-Closing Balance Sheet for each McNeil Partnership shall be accompanied by a
schedule setting forth the Preliminary Excess Cash Balance for such McNeil
Partnership in the form attached as Annex D hereto (the "Preliminary Excess Cash
Balance Schedule"), which shall be prepared in accordance with the methodology
and principles set forth on Annex D hereto.

               (b)(i) Within four (4) business days (the "Objection Period")
        after the delivery by MPLP to the Company of the Preliminary Pre-Closing
        Balance Sheet and Preliminary Excess Cash Balance Schedule for a McNeil
        Partnership and all relevant books and records and any work papers
        (including those of Arthur Andersen LLP, Sellers' accountants) relating
        to the preparation of such Preliminary Pre-Closing Balance Sheet and
        such Preliminary Excess Cash Balance Schedule (including unaudited
        statements of operations and cash flows (prepared in accordance with
        GAAP applied consistently with past practice), bills, receipts and other
        written correspondence evidencing any amounts of Transaction Expenses),
        the Company and its accountants shall complete their review of such
        Preliminary Pre-Closing Balance Sheet and such Preliminary Excess Cash
        Balance Schedule. Sellers shall make readily available to the Company,
        on a timely basis during the Objection Period, all relevant books and
        records and any work papers



                                       17
<PAGE>

        (including those of Arthur Andersen LLP, Sellers' accountants) relating
        to the preparation of the Preliminary Pre-Closing Balance Sheets and the
        Preliminary Excess Cash Balance Schedules (including unaudited
        statements of operations and cash flows, bills, receipts and other
        written correspondence evidencing any amounts of Transaction Expenses)
        and all other items reasonably requested by the Company. In addition,
        Sellers and the Company shall make their relevant personnel reasonably
        available to each other to respond to inquiries relating to any of the
        materials described in the preceding sentence or any matters raised by
        the Company. On or before the last day of the Objection Period, the
        Company shall deliver to MPLP a reasonably detailed written statement of
        any objections or disagreements, including the reasons therefor, with
        respect to any Preliminary Pre-Closing Balance Sheet and Preliminary
        Excess Cash Balance Schedule (the "Objection Statement") (it being
        understood that neither the inclusion on any Preliminary Excess Cash
        Balance Schedule of any line item not listed on Annex D hereto nor the
        exclusion from any Preliminary Excess Cash Balance Schedule of any line
        item listed on Annex D hereto shall be the subject of any such objection
        or disagreement). If the Company does not provide MPLP with the
        Objection Statement with respect to the Preliminary Pre-Closing Balance
        Sheet or the Preliminary Excess Cash Balance Schedule with respect to a
        McNeil Partnership within the Objection Period, the parties hereto shall
        be deemed to have unconditionally accepted and agreed to, and shall be
        unconditionally bound by, the Preliminary Pre-Closing Balance Sheet, the
        Preliminary Excess Cash Balance Schedule and the Preliminary Excess Cash
        Balance set forth on such Preliminary Excess Cash Balance Schedule, in
        each case, with respect to such McNeil Partnership, other than with
        respect to the Specified Transaction Expenses which shall be updated to
        a subsequent date in accordance with Note 17 to the Excess Cash Balance
        Schedule.

                      (ii) In the event that the Company delivers to MPLP an
        Objection Statement with respect to a Preliminary Pre-Closing Balance
        Sheet or the



                                       18
<PAGE>

        Preliminary Excess Cash Balance Schedule with respect to a McNeil
        Partnership within the Objection Period, the Company and MPLP shall have
        two (2) business days (the "Resolution Period") following the receipt by
        MPLP of such Objection Statement to resolve any disagreements set forth
        in the Objection Statement. If the Company and MPLP are unable to
        resolve all of their disagreements set forth in the Objection Statement
        within the Resolution Period, the Company and MPLP shall, promptly
        following the Resolution Period, submit their remaining differences to a
        nationally recognized firm of independent public accountants which shall
        be chosen by mutual agreement of the Company and MPLP or, in the event
        the Company and MPLP are unable to agree, a firm chosen jointly by the
        accountants of each of them (the "CPA Firm"). The CPA Firm, acting as
        experts and not as arbitrators, shall determine, by applying the
        methodology and principles set forth on Annex D hereto, and only with
        respect to the remaining differences so submitted, whether and to what
        extent, if any, the Preliminary Pre-Closing Balance Sheet or the amounts
        set forth on the Preliminary Excess Cash Balance Schedule should be
        revised. The Company and MPLP shall instruct the CPA Firm to deliver its
        written determination to the Company and MPLP no later than two (2)
        business days after such remaining differences are referred to the CPA
        Firm (unless the Company and MPLP agree in writing, upon request of the
        CPA Firm, to provide the CPA Firm with additional time to make its
        determination); provided, however, that such determination shall be made
        no later than the day immediately prior to the estimated Closing Date.
        The CPA Firm's determination relating to each Preliminary Pre-Closing
        Balance Sheet and each Preliminary Excess Cash Balance Schedule
        submitted to it shall be conclusive and binding upon the parties hereto.
        The fees and disbursements of the CPA Firm shall be shared equally by
        the Company, on the one hand, and Sellers, on the other hand. Sellers
        shall make readily available to the CPA Firm, on a timely basis during
        the period the CPA Firm is making its determination pursuant to this
        Section 2.4(b)(ii), all relevant books and records and any work papers
        (including those of Arthur Andersen LLP, Sellers'



                                       19
<PAGE>

        accountants) relating to the preparation of the Preliminary Pre-Closing
        Balance Sheets and Preliminary Excess Cash Balance Schedules (including
        unaudited statements of operations and cash flows, bills, receipts and
        other written correspondence evidencing any amounts of Transaction
        Expenses) and all other items reasonably requested by the CPA Firm. In
        addition, Sellers and the Company shall make their relevant personnel
        reasonably available to the CPA Firm and each other to respond to any
        inquiries relating to the disagreements submitted to the CPA Firm.

                      (iii) Each Preliminary Pre-Closing Balance Sheet,
        Preliminary Excess Cash Balance Schedule and Preliminary Excess Cash
        Balance set forth on such Preliminary Excess Cash Balance Schedule after
        having been deemed to be accepted by the parties hereto pursuant to the
        last sentence of Section 2.4(b)(i) hereof or the CPA Firm's
        determinations in respect thereof pursuant to Section 2.4(b)(ii) hereof
        are, respectively, referred to herein as the "Pre-Closing Balance
        Sheet," "Excess Cash Balance Schedule" and the "Excess Cash Balance."

               (c) For each Participating McNeil Partnership for which the
Excess Cash Balance is greater than zero (a "Positive Excess Cash Balance"),
MPLP shall cause such Participating McNeil Partnership, on the Closing Date and
immediately prior to the consummation of any of the transactions contemplated by
Section 2.3(a) hereof, to irrevocably declare a cash distribution, in an amount
equal to the Positive Excess Cash Balance for such Participating McNeil
Partnership, to the persons who were limited partners (prior to the consummation
of any of the transactions contemplated by Section 2.3(a) hereof) of such
Participating McNeil Partnership as a special distribution in accordance with
the limited partnership agreement of such Participating McNeil Partnership. For
each Participating McNeil Partnership for which the Excess Cash Balance is less
than zero, the "Negative Excess Cash Balance" in respect of such Participating
McNeil Partnership shall be an amount equal to such negative Excess Cash
Balance. The Company and the Participating McNeil Partnerships agree to take
such actions as may be



                                       20
<PAGE>

necessary to effect the distributions contemplated by this Section 2.4(c)
concurrently with the payment of the Merger Consideration to former holders of
LP Interests pursuant to Section 3.5 hereof.

               (d) On and following the date of the Preliminary Pre-Closing
Balance Sheet for a McNeil Partnership, such McNeil Partnership shall not
declare any distributions with respect to any GP Interest or LP Interest in such
McNeil Partnership prior to the Effective Time, except for the distributions
contemplated by Section 2.4(c) hereof in the event such McNeil Partnership is a
Participating McNeil Partnership and except for Post-Allocation Upstream
Payables accruing through to the Closing Date.

               (e) The parties hereto acknowledge and agree that immediately
upon the declaration of the Positive Excess Cash Balance, the amount of such
special distribution shall become final and binding upon the parties hereto and
shall not be offset against any other amounts due, payable or owing by any
person under this Agreement or the Ancillary Agreements (regardless of any
subsequent recalculation of the Excess Cash Balance).

               (f) If the estimated Closing Date is delayed for more than ten
(10) business days and such estimated Closing Date falls more than forty-five
days after the last date of the fiscal month for which the preceding Preliminary
Pre-Closing Balance Sheet and Preliminary Pre-Closing Excess Cash Schedule for a
McNeil Partnership were prepared, MPLP and the Company shall each have the right

hereof, a new Preliminary Pre-Closing Balance Sheet (the "New Preliminary
Pre-Closing Balance Sheet") and a new Preliminary Excess Cash Balance Schedule
(the "New Preliminary Excess Cash Balance Schedule"), setting forth a new
Preliminary Excess Cash Balance (the "New Preliminary Excess Cash Balance"), for
such McNeil Partnership. Each such New Preliminary Pre-Closing Balance Sheet,
New Preliminary Excess Cash Balance Schedule and New Preliminary Excess Cash
Balance shall be subject to the provisions of Sections 2.4(a) through 2.4(e)
hereof and shall become final and binding on the parties hereto in accordance
with Section 2.4(b) hereof; provided, however, that each party hereto
acknowledges and



                                       21

agrees that none of the preparation, delivery, acceptance or resolution of
disagreements with respect to any New Preliminary Pre-Closing Balance Sheet, New
Preliminary Excess Cash Balance Schedule or New Preliminary Excess Cash Balance
shall delay the Closing if the Closing would otherwise be required to occur
pursuant to the terms of this Agreement had the preparation and delivery of such
items not been requested. If the Closing would otherwise be required to occur,
or has otherwise occurred prior to the time at which the New Preliminary
Pre-Closing Balance Sheet, New Preliminary Excess Cash Balance Schedule and New
Preliminary Excess Cash Balance for a McNeil Partnership becomes final and
binding on the parties hereto in accordance with Section 2.4(b) hereof, the
parties acknowledge and agree that they shall be bound by the immediately
preceding Pre-Closing Balance Sheet, Excess Cash Balance Schedule and Excess
Cash Balance for such McNeil Partnership which has become final and binding on
the parties hereto in accordance with Section 2.4(b) hereof. Without limiting
the foregoing, in the event that prior to the Closing a New Preliminary
Pre-Closing Balance Sheet, a New Preliminary Excess Cash Balance Schedule and a
New Preliminary Excess Cash Balance for a McNeil Partnership have been deemed to
be accepted by all parties hereto pursuant to the last sentence of Section
2.4(b)(i) hereof or all disputes in connection therewith are resolved pursuant
to Section 2.4(b)(ii) hereof, respectively, references herein to the
"Pre-Closing Balance Sheet," the "Excess Cash Balance Schedule" and the "Excess
Cash Balance" for such McNeil Partnership shall be deemed to refer to such New
Preliminary Pre-Closing Balance Sheet, such New Excess Cash Balance Schedule and
such New Excess Cash Balance, respectively.

               (g) Notwithstanding anything to the contrary set forth in this
Agreement, in connection with the matters contemplated by this Section 2.4, the
parties hereto acknowledge and agree that Sellers shall not be required to
deliver any work papers of Arthur Andersen LLP if the recipients thereof do not
execute a confidentiality agreement substantially comparable to the one entered

               (a) Each LP Interest of each class of LP Interests in each of the
Participating Merging Partnerships outstanding immediately prior to the

cash (without interest thereon) in an amount equal to the Per Unit Consideration
Amount to which such LP Interest is entitled under the respective limited
partnership agreement of such Participating Merging Partnership upon surrender
of the Certificate(s) representing such LP Interest for cancellation (or, in the
case of an LP Interest in a Participating Merging



                                       24
<PAGE>

Partnership which is a Merging Private Partnership, upon the delivery of the
affidavit made in accordance with Section 3.5(d) hereof) to the Payment Agent.
As of the Effective Time, each such LP Interest in each of the Participating

cancelled and retired and shall cease to exist, and each holder of an LP
Interest shall cease to have any rights with respect thereto, except the right

               (b) As of the Effective Time, each LP Interest in each Transitory

into one fully issued and nonassessable LP Interest in the Surviving Partnership
in each Merger between such Transitory Partnership and its corresponding
Participating Merging Partnership.

               (c) Each GP Interest in each of the Participating Merging
Partnerships outstanding immediately prior to the Effective Time shall be
converted into and shall become one fully paid and nonassessable GP Interest in
the Surviving Partnership in each Merger. As of the Effective Time, each GP
Interest in each Transitory Partnership shall no longer be outstanding and shall
automatically be cancelled and retired and shall cease to exist, and each holder
of such GP Interests shall cease to have any rights in respect thereto.

               Section 3.5 Payment of Merger Consideration.

               (a) At the Effective Time, as required by Section 3.5(b) hereof,
the Company shall deposit with such agent or agents as may be appointed by the
Company (the "Payment Agent") for the benefit of the holders of LP Interests in
the Participating Merging Partnerships, cash in an aggregate amount equal to the
sum of the Participating Partnership Consideration Amounts for each
Participating McNeil Partnership (such sum, the "Merger Consideration," and the
Merger Consideration deposited



                                       25
<PAGE>

with the Payment Agent is referred to as the "Merger Fund").

               (b) Immediately following the Effective Time, the Payment Agent
shall mail to each holder of record of certificate(s) which immediately prior to
the Effective Time represented outstanding LP Interests in the Participating
Merging Partnerships (the "Certificates") and which were converted into the
right to receive the Merger Consideration pursuant to Section 3.4 hereof (or, in
the case of any Participating Merging Partnership which is a Merging Private
Partnership, each holder of record of an LP Interest in such Merging Private
Partnership): (i) a letter of transmittal (which shall specify that delivery
shall be effected and risk of loss and title to the LP Interests shall pass to
the Company only upon delivery of the Certificates (or, in the case of any
Participating Merging Partnership which is a Merging Private Partnership, upon
the delivery by such holder of record of appropriate documentation and the
delivery by MPLP of the affidavit specified in Section 3.5(d) hereof) to the
Payment Agent and shall be in such form and have such other provisions as the
Company may reasonably specify); and (ii) instructions for effecting the
surrender of the Certificates (or delivery of such appropriate documentation and
affidavit) in exchange for the Per Unit Consideration Amount which such holder
has the right to receive pursuant to Section 3.4 hereof (taking into account
different classes (if any) of LP Interests in such Participating Merging
Partnership). Upon surrender of a Certificate for cancellation (or delivery of
such appropriate documentation and affidavit) to the Payment Agent together with
such letter of transmittal duly executed, the holder of such LP Interests shall
be entitled to receive in exchange therefor a check representing the Per Unit
Consideration Amount which such holder has the right to receive pursuant to
Section 3.4 hereof, and any Certificates so surrendered shall forthwith be
cancelled. In the event of a transfer of ownership of LP Interests in a
Participating Merging Partnership which is not registered in the transfer
records of such Participating Merging Partnership, payment of the Per Unit
Consideration Amount which such holder has the right to receive pursuant to
Section 3.4 hereof may be made to a transferee if the Certificate representing
such



                                       26
<PAGE>

LP Interests (or, in the case of any Participating Merging Partnership which is
a Merging Private Partnership, if the affidavit specified in Section 3.5(d)
hereof and a suitable bond or indemnity) is presented to the Payment Agent
accompanied by all documents required to evidence and effect such transfer.
Until surrendered as contemplated by this Section 3.5, each Certificate shall be
deemed at and after the Effective Time to represent only the right to receive
upon such Certificate's surrender the Per Unit Consideration Amount which the
holder of such Certificate has the right to receive pursuant to Section 3.4
hereof. The Surviving Partnerships shall have the right to, and shall, take all
steps necessary to ensure compliance, and shall comply, with all withholding
obligations with respect to any foreign holders of LP Interests in connection
with the payment of any Per Unit Consideration Amount. No interest will be paid
or will accrue on any Per Unit Consideration Amount upon the surrender of any
Certificate.

               (c) In the event that any Certificate shall have been lost,
stolen or destroyed, the Payment Agent shall issue in exchange therefor, upon
the making of an affidavit of that fact by the holder thereof, the Per Unit
Consideration Amount which the holder of such Certificate has the right to
receive pursuant to Section 3.4 hereof; provided, however, that the Payment
Agent shall (unless the Company determines otherwise) require the delivery of a
suitable bond or indemnity, the form of which bond or indemnity shall be
acceptable to the Company.

               (d) In the case of LP Interests in the Participating Merging
Partnerships which are Merging Private Partnerships, the Payment Agent shall
issue in exchange therefor, upon the making of an affidavit as to the identity
of each owner of LP Interests in such Merging Private Partnership by MPLP (in
the case of Hearth Hollow and Midwest Properties) and Robert A. McNeil (in the
case of Regency North), the Per Unit Consideration Amount which the holder of LP
Interests therein has the right to receive pursuant to Section 3.4 hereof.

               (e) All Merger Consideration paid upon the surrender for exchange
of LP Interests in the Participating Merging Partnerships in accordance with the




                                       27
<PAGE>

terms of this Agreement shall be deemed to have been paid in full satisfaction
of all rights pertaining to such LP Interests; provided, however, that
notwithstanding anything to the contrary contained in this Agreement, the
Surviving Partnership in each of the Mergers shall continue to have an
obligation following the Effective Time (i) to pay distributions with a record
date prior to the Effective Time which may have been declared by a Participating
Merging Partnership on LP Interests in such Participating McNeil Partnership in
accordance with the terms of this Agreement or declared prior to the date of
this Agreement and, in either case, which remain unpaid at the Effective Time
and (ii) to distribute to the former limited partners of each Participating
Merging Partnership the Positive Excess Cash Balance (if any) in respect of such
Participating Merging Partnership in accordance with Section 2.4(c) hereof. From
and after the Effective Time, there shall be no further registration of
transfers on the transfer books of the Surviving Partnerships of LP Interests in
the Participating Merging Partnerships which were outstanding immediately prior
to the Effective Time. If, after the Effective Time, Certificates are presented
to the Surviving Partnerships for any reason, such Certificates shall be
canceled and exchanged as provided in this Section 3.5. If, after the Effective
Time, owners of LP Interests in any Merging Private Partnerships who are
identified on the affidavits described in Section 3.5(d) hereof request payment
in respect of such LP Interests from the Surviving Partnerships for any reason,
the Per Unit Consideration Amount which such owner has the right to receive
pursuant to Section 3.4 hereof and which has not theretofore been paid to such
owner shall be delivered to such owner in exchange for such LP Interests.

               (f) None of the Payment Agent, the parties to this Agreement, the
Transitory Partnerships, the Company LLCs or any of their respective affiliates
shall be liable to any holder of an LP Interest in a Participating Merging
Partnership for cash from the Merger Fund delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

               (g) Any portion of the Merger Fund which remains undistributed to
the holders of LP Interests in the Participating Merging Partnerships for a
period of six



                                       28
<PAGE>

months after the Effective Time shall be delivered to the Company, upon demand
of the Company, and any such holder who has not theretofore complied with this
Section 3.5 shall thereafter look only to the Company for payment of the Per
Unit Consideration Amount which such holder had the right to receive pursuant to
Section 3.4 hereof, and any unpaid distributions, subject to applicable escheat
and other similar laws. The McNeil Partnerships shall pay all charges and
expenses relating to the Mergers, and the Company shall reimburse the McNeil
Partnerships, on the Closing Date and immediately prior to the distributions
contemplated by Section 2.4(c) hereof, in an amount in cash equal to one-half of
the amount of the charges and expenses relating to the Payment Agent (the
"Merger Expense Reimbursement").

               (g) Sellers have made available to the Company true, complete and
accurate copies of all leases for space as of the date of this Agreement in the
McNeil Partnership Properties identified on Annex E hereto as "Commercial

               Section 4.9 Environmental Matters. For purposes of this Section
4.9, the term "Hazardous Material" means any substance, material or waste which
is regulated in any concentration or is otherwise defined by any federal, state
or local governmental body under Environmental Law as a "hazardous waste,"
"hazardous material," "hazardous substance," "extremely hazardous waste,"
"restricted hazardous waste," "contaminant," "toxic waste" or "toxic substance"
under any provision of Environmental Law, which includes petroleum, petroleum

disclosed on Schedule 4.9 of the Seller Disclosure Letter or in the reports

Material Adverse Effect:



                                       53
<PAGE>

               (a) To the Knowledge of Sellers, there is not present in, on or
under any McNeil Partnership Property any Hazardous Material in such form or
quantities as to create, and Sellers and the Seller Subsidiaries have not
created, any liability or obligation under federal, state, local or other
governmental statute, law (including common law), ordinance or regulation,
relating to, or dealing with the protection of human health or the environment
in effect as of the date of this Agreement ("Environmental Law") for any McNeil
Partnership;

               (b) There is no pending request, claim, written notice,
investigation, demand, administrative proceeding, hearing or litigation, nor, to
the Knowledge of Sellers, is one threatened, alleging liability under, violation
of, or noncompliance with any Environmental Law or any license, permit or other
authorization issued pursuant thereto ("Environmental Complaints") relating to
any McNeil Partnership Property (or any real property formerly owned or operated
by any of the McNeil Partnerships or any of the Seller Subsidiaries) and against
Sellers or the Seller Subsidiaries, and there is no reasonable basis for
believing that circumstances or conditions exist which would support any such
Environmental Complaint against Sellers or the Seller Subsidiaries relating to
the McNeil Partnership Properties;

               (c) Sellers have developed and implemented appropriate operation
and maintenance programs for all of the McNeil Partnership Properties which
contain "Asbestos Containing Materials," have complied with all applicable
regulations of the Occupational Health and Safety Administration regarding
asbestos notification to workers and tenants, and have complied with all
applicable provisions of the Lead Based Paint Hazard Reduction Act of 1992 and
all regulations promulgated thereto;

               (d) The McNeil Partnership Properties comply with all
Environmental Laws;

               (e) To the actual knowledge, without any inquiry of or
investigation by, the individuals listed on Schedule 10.1(a) of the Seller
Disclosure Letter, no real property formerly owned or operated by any of the
McNeil Partnerships or any of the Seller Subsidiaries was



                                       54
<PAGE>

contaminated with any Hazardous Material during or prior to such period of
ownership or operations; and

               (f) Sellers have made available to the Company copies of all
material environmental reports, studies, assessments, sampling data and other
environmental information, in each case, that is in their possession and that
relates to Sellers or the Seller Subsidiaries or their respective current
properties or operations.

               Section 4.10  Taxes.

               (a) Except as set forth on Schedule 4.10 of the Seller Disclosure
Letter, each McNeil Partnership and its respective Seller Subsidiaries has
prepared in good faith and timely filed all Tax returns and reports required to
be filed by it (after giving effect to any filing extension properly granted by
a Governmental Entity having authority to do so) and has paid (or has had paid
on its behalf) all Taxes shown on such returns and reports as required to be
paid by it or that each McNeil Partnership is obligated to withhold from amounts
owing to any employee, creditor or third party. Except as set forth on Schedule
4.10 of the Seller Disclosure Letter, to the Knowledge of Sellers, all Tax
returns are complete, correct and accurate and the McNeil Partnerships and their
respective Seller Subsidiaries are not required to pay any Taxes other than as
shown on such returns. Except for Taxes that are being contested in good faith
by appropriate proceedings and for which such McNeil Partnership shall have set
aside on its books adequate reserves, which are set forth on Schedule 4.10 of
the Seller Disclosure Letter, none of the McNeil Partnerships is being audited
by any Governmental Entity and there are no pending or, to the Knowledge of
Sellers, threatened audits, examinations, investigations or other proceedings in
respect of Taxes or Tax matters. The most recent audited McNeil Partnership
Statements contained in the Seller SEC Documents or made available to the
Company, as the case may be, reflect an adequate reserve for all material Taxes
payable by the McNeil Partnerships and their respective Seller Subsidiaries for
all taxable periods and portions thereof through the date of such financial
statements, which Taxes are material to the McNeil Partnerships and their
respective Seller



                                       55
<PAGE>

Subsidiaries taken as a whole. Except as set forth on Schedule 4.10 of the
Seller Disclosure Letter, to the Knowledge of Sellers, no deficiencies for any
Taxes have been proposed, asserted or assessed against the McNeil Partnerships
and their respective Seller Subsidiaries, and no requests for waivers of the
time to assess any such Taxes are pending. As used in this Agreement, "Taxes"
includes all federal, state, local and foreign income, property, franchise,
employment, excise and other taxes together with penalties, interest or
additions to Tax with respect thereto (but shall not include any sales or use
taxes).

               (b) The McNeil Partnerships and the Seller Subsidiaries that have
been partnerships, joint ventures or disregarded entities or limited liability
companies since formation have at all times qualified as partnerships or
disregarded entities for federal income tax purposes. The McNeil Partnerships
and the Seller Subsidiaries that have been partnerships, joint ventures or
disregarded entities or limited liability companies since formation are not
publicly traded partnerships within the meaning of Section 7704 of the Internal
Revenue Code of 1986, as amended (the "Code"), or otherwise taxable as an
association for federal income tax purposes.

               Section 4.11 No Payments to Employees, Officers or Directors.

or as otherwise provided for in this Agreement, there is no employment or
severance contract, or other plan, arrangement or agreement, entitling any
employees of McREMI or the officers of any Seller Corporation to severance pay,
or requiring, accelerating the time of payment or vesting, increasing or
triggering payments or funding (through a grantor trust or otherwise) of
compensation or benefits, cancellation of indebtedness or other obligation
(collectively, "Severance Obligations") to be made on a change of control or
otherwise as a result of the consummation of the transactions contemplated by
this Agreement and the other Transaction Documents, with respect to any present
or former employee, officer or director of McREMI or such Seller Corporation.

               Section 4.13  Employee Benefits.

               (a) Schedule 4.13 of the Seller Disclosure Letter contains a true
and complete list as of the date of this Agreement of each: "welfare plan,"
fund, contract, policy or program (within the meaning of section 3(1) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")); "pension
plan," fund or program (within the meaning of section 3(2) of ERISA);
employment, termination or severance agreement; and other employee benefit plan,
fund, program, contract agreement or arrangement, in each case, that is
sponsored, maintained or contributed to or required to be contributed to by
McREMI or by any trade or business, whether or not incorporated, that together
with McREMI would be deemed a "single employer" within the meaning of section
4001(b) of ERISA (a "McREMI ERISA Affiliate"), or to which McREMI or any McREMI
ERISA Affiliate is party, for the benefit of any employee or former employee of
McREMI (the "McREMI Plans").

               (b) With respect to each McREMI Plan, McREMI has heretofore made
available to the Company true and complete copies of such McREMI Plan and any
amendments thereto, any related trust insurance contract or other funding
vehicle, any reports or summaries required under ERISA or the Code and the most
recent determination letter received from the Internal Revenue Service with
respect to each McREMI Plan intended to qualify under section 401 of the Code.

               (c) No liability under Title IV or section 302 of ERISA has been
incurred by McREMI or any McREMI ERISA Affiliate with respect to any ongoing,
frozen or terminated "single-employer plan," within the meaning of Section
4001(a)(15) of ERISA, currently or formerly maintained by any of them, or the
single-employer plan of a McREMI ERISA Affiliate, that has not been satisfied in


                                       57
<PAGE>

full, and, to the Knowledge of Sellers, no condition exists that presents a
material risk to McREMI or any McREMI ERISA Affiliate of incurring any such
liability, other than liability for premiums due the Pension Benefit Guaranty
Corporation (which premiums have been paid when due).

               (d) No McREMI Plan is a "multiemployer pension plan," as defined
in section 3(37) of ERISA, and neither McREMI nor any McREMI ERISA Affiliate has
contributed to a multiemployer plan at any time on or after September 1, 1980.
No notice of a "reportable event", within the meaning of Section 4043 of ERISA
for which the 30-day reporting requirement has not been waived, has been
required to be filed for any McREMI Plan or by any McREMI ERISA Affiliate within
the twelve-month period ending on the date hereof or will be required to be
filed in connection with the transactions contemplated by this Agreement.

               (e) Each McREMI Plan has been operated and administered in all
material respects in accordance with its terms and applicable law, including but
not limited to ERISA and the Code.

               (f) Each McREMI Plan intended to be "qualified" within the
meaning of section 401(a) of the Code has received a favorable determination
letter from the Internal Revenue Service stating that it is so qualified, and,
to the Knowledge of Sellers, no event has occurred since the date of such
determination that would adversely affect such determination.

               (g) There are no pending or, to the Knowledge of Sellers,
anticipated claims by or on behalf of any McREMI Plan, by any employee or
beneficiary covered under any such McREMI Plan, or otherwise involving any such
McREMI Plan (other than routine claims for benefits). None of Sellers nor any of
the Seller Subsidiaries has engaged in a transaction with respect to any McREMI
Plan that, assuming the taxable period of such transaction expired as of the
date hereof or as of the Closing Date, could subject McREMI, any McNeil
Partnership or any Seller Subsidiary to a tax or penalty imposed by either
Section



                                       58
<PAGE>

4975 of the Code or Section 502(i) of ERISA in an amount which would be
material.

               (h) All contributions required to be made under the terms of any
McREMI Plan have been timely made or have been reflected on the audited or
unaudited balance sheet of McREMI made available to the Company.

               (i) McREMI has no obligations for retiree health and life
benefits under any McREMI Plan. McREMI may amend or terminate any such McREMI
Plan at any time without incurring any liability thereunder, other than claims
for benefits accrued prior to the Effective Time.

               Section 4.14  Employee Matters.

               (a) Except for the officers of the Seller Corporations set forth
on Schedule 4.14(a) of the Seller Disclosure Letter, none of the McNeil
Partnerships nor any of their respective Seller Subsidiaries has any employees.

               (b) Schedule 4.14(b) of the Seller Disclosure Letter lists the
employee handbooks of McREMI in effect as of the date of this Agreement. A copy
of each such employee handbook has been made available to the Company. Except as
set forth on Schedule 4.14(b) of the Seller Disclosure Letter, such handbooks
fairly and accurately summarize all material employee policies, vacation
policies and payroll practices of McREMI.

               Section 4.15  Contracts; Debt Instruments.

               (a) Except as set forth on Schedule 4.15(a) of the Seller
Disclosure Letter, none of Sellers or the Seller Subsidiaries has received a
written notice that any Seller or any Seller Subsidiary is in violation of or in
default under, nor does there exist any condition which upon the passage of time
or the giving of notice or both would cause such a violation of or default
under, any loan or credit agreement, note, bond, mortgage, indenture, lease,
permit, concession, franchise, license or any other material contract,
agreement, arrangement or understanding (each, a "Material Contract"), to which
it is a party or by which it or any of its properties or assets is bound, nor
does such a violation or default exist, except to the



                                       59
<PAGE>

extent that such violation or default, individually or in the aggregate, would
not have a Seller Material Adverse Effect or prevent the consummation of the
transactions contemplated by this Agreement and the other Transaction Documents
to which such Seller is a party. Each Material Contract which has not been filed
as an exhibit to any of the Seller SEC Documents has been previously made
available to the Company (except as noted on Schedule 4.15(a) of the Seller
Disclosure Letter) and a list of all Material Contracts that have not been so
filed is set forth in Schedule 4.15(a) of the Seller Disclosure Letter. Except
as set forth in the Seller SEC Documents filed prior to the date hereof or on
Schedule 4.15(a) of the Seller Disclosure Letter, there is no contract or
agreement that purports to limit in any material respect the geographic location
in which McREMI, any of the McNeil Partnerships or any of the Seller
Subsidiaries may conduct its business.

               (b) Except for any of the following expressly identified in the
Seller SEC Documents, Schedule 4.15(b) of the Seller Disclosure Letter sets
forth a list, as of the date of this Agreement, of each loan or credit
agreement, note, bond, mortgage, indenture, security agreement, financing
statement and any other material agreement and instrument and all amendments
thereto pursuant to which any Indebtedness of Sellers or any Seller Subsidiary
is outstanding or may be incurred or secured. For purposes of this Agreement,
"Indebtedness" means (i) indebtedness for borrowed money, whether secured or
unsecured, (ii) obligations under conditional sale or other title retention
agreements relating to property purchased by such person, (iii) capitalized
lease obligations, (iv) obligations under any interest rate cap, swap, collar or
similar transaction or currency hedging transactions (valued at the termination
value thereof) and (v) guarantees of any such Indebtedness of any other person.

               (c) Except as set forth on Schedule 4.15(b) of the Seller
Disclosure Letter, as of the date of this Agreement, there is no interest rate
cap, interest rate collar, interest rate swap, currency hedging transaction or
any other agreement relating to a similar transaction


                                       60
<PAGE>

to which any Seller or any Seller Subsidiary is a party or an obligor with
respect thereto.

               (d) Except as set forth on Schedule 4.15(d) of the Seller
Disclosure Letter, none of Sellers nor any Seller Subsidiary is party to any
agreement which would restrict any of them from prepaying any of their material
Indebtedness without penalty or premium at any time or which requires any of

business and will be in good standing (with respect to jurisdictions which

or the ownership, leasing or use of its properties makes such qualification or

contemplated by this Agreement and the other Transaction Documents to which the
Company is a party. The Company has delivered to Sellers complete and correct
copies of the Original LLC Agreement, as amended or supplemented to the date of
this Agreement. The Company was formed solely for the purpose of engaging in the

properties makes such



                                       65
<PAGE>

qualification or licensing necessary, other than in such jurisdictions where the
failure to be so qualified or licensed or to be in good standing, individually
or in the aggregate, would not prevent the consummation of the transactions

correct copies of the formation documents of each Company LLC and each
Transitory Partnership. Each Company LLC and each Transitory Partnership will be
formed solely for the purpose of engaging in the transactions contemplated by

                                       71
<PAGE>

other Transaction Documents to which the Company, any Company LLC or any

Company LLC or any Transitory Partnership is a party, and (ii) there is no
judgment, decree, rule or order of any Governmental Entity or arbitrator

whether express or implied), the Company acknowledges and agrees that its
obligation to effect the transactions contemplated by this Agreement and the
other Transaction Documents is not subject to the availability to Whitehall, the

               (a) During the period from the date hereof through to the Closing
Date, Sellers shall have the option of presenting to the Company one or more

                                       82
<PAGE>

Commercial Leases or the lease of additional space to an existing Commercial
Tenant (each such capital expenditure, tenant inducement or commission proposal,
a "Reimbursable Proposal"). In addition, the parties hereto acknowledge that on
or prior to the date of this Agreement, Sellers have presented to the Company,
and the Company has approved, the Reimbursable Proposals and the budgeted
amounts therefor listed on Schedule 6.3 of the Seller Disclosure Letter.

               (b) To the extent any one or more Reimbursable Proposals with
respect to any Participating McNeil Partnership have been approved by the
Company on or prior to the date hereof or are approved by the Company (which
approval shall not be unreasonably withheld or delayed) subsequent to the date
hereof, the Company shall make a cash contribution to such Participating McNeil
Partnership, prior to the distributions contemplated by Section 2.4(c) hereof,
in an amount equal to the Capital Expenditure Reimbursement for such
Participating McNeil Partnership which shall be taken into consideration in the
determination of the Excess Cash Balance of such Participating McNeil
Partnership in accordance with the Excess Cash Balance Schedule for such
Participating McNeil Partnership.

               (c) For purposes of this Agreement, the following terms shall
have the following meanings:

                      (i) "Capital Expenditure Reimbursement" means, for any
        McNeil Partnership, the sum of the Capital Expenditure Reimbursement
        Amounts for each Reimbursable Proposal for such McNeil Partnership.

                      (ii) "Capital Expenditure Reimbursement Amount" means, for
        each Reimbursable Proposal, an amount equal to the product determined by
        multiplying (A) the Reimbursable Proposal Amount for such Reimbursable
        Proposal by (B) a fraction (in no event shall such fraction be greater
        than one (1)), the numerator of which is the number of months (including
        any fraction thereof) in the period beginning on the estimated Closing
        Date and ending on the last day of the initial term of the applicable
        Commercial Lease and the denominator of which is the aggregate number



                                       83
<PAGE>

        of months in the initial term of the applicable Commercial Lease.

                      (iii) "Completed Amount" means, for any Reimbursable
        Proposal, an amount equal to the aggregate amount expended or incurred
        through to the estimated Closing Date in connection with such
        Reimbursable Proposal.

                      (iv) "Reimbursable Proposal Amount" means, for any
        Reimbursable Proposal, an amount equal to the lesser of (1) the
        Completed Amount and (2) the total budgeted amounts for such
        Reimbursable Proposal; provided, however, that for any Reimbursable
        Proposal which will be uncompleted as of the estimated Closing Date, the
        "Reimbursable Proposal Amount" for such Reimbursable Proposal shall be
        an amount equal to the difference determined by subtracting (x) the
        Underbudgeted Amount (if any) for such Reimbursable Proposal from (y)
        the Completed Amount for such Reimbursable Proposal.

                      (v) "Underbudgeted Amount" means, for any Reimbursable
        Proposal, the excess (if any) of (1) the sum of (A) the Completed Amount
        and (B) the estimated additional amount (which is reasonably and in good
        faith jointly determined by the Company and MPLP) required to be
        expended or incurred following the estimated Closing Date to complete
        such Reimbursable Proposal over (2) the total budgeted amounts for such
        Reimbursable Proposal.

                              ADDITIONAL COVENANTS

               Section 7.1 Preparation of the Proxy Statement; Recommendation of
Mergers.

               (a) With respect to each Merging Partnership, Sellers shall
prepare (and, in the case of each of the Public McNeil Partnerships, file with
the SEC) as soon as practicable after the date of this Agreement, but in any
event not later than August 31, 1999, which date may be



                                       84
<PAGE>

extended by Sellers (subject to approval of the Company, which shall not be
unreasonably withheld or delayed) or by the Company, a proxy statement with
respect to the McNeil Limited Partner Meeting of such Merging Partnership to
approve the Merger in respect of such Merging Partnership, the MPLP
Contributions with respect to such Merging Partnership, the appointment of the
applicable New GP LLC as the successor general partner of such Merging
Partnership and the other transactions contemplated by this Agreement (each, a
"Proxy Statement"). If required by law, Sellers and any person that may be
deemed to be an affiliate of any Public McNeil Partnership shall prepare and
file concurrently with the filing of the Proxy Statement for such Public McNeil
Partnership a Statement on Schedule 13E-3 (each, a "Schedule 13E-3") with the
SEC with respect to such Public McNeil Partnership. The Company shall, upon
request by Sellers, furnish Sellers with such information concerning itself, the
Managing Member and Whitehall as may be required by law or by any Governmental
Entity in connection with any Proxy Statement, any Schedule 13E-3 or any other
statement, filing, notice or application made by or on behalf of the Company to
any third party or any Governmental Entity or both in connection with the
Mergers, the MPLP Contributions, the appointments of the applicable New GP LLCs
as the successor general partners of the McNeil Partnerships and the other
transactions contemplated by this Agreement. Sellers shall use their reasonable
best efforts to (i) promptly respond to any comments of the SEC and (ii) cause
the respective Proxy Statements to be mailed to the limited partners of the
respective Merging Partnerships as promptly as practicable after the date of
this Agreement. Sellers shall notify the Company promptly of the receipt of any
comments from the SEC and of any request by the SEC for amendments or
supplements to any Proxy Statement or any Schedule 13E-3 or for additional
information and shall supply the Company with copies of all correspondence
between Sellers or any of their representatives, on the one hand, and the SEC,
on the other hand, with respect to any Proxy Statement or any Schedule 13E-3.
The Proxy Statements for the Public McNeil Partnerships and the Schedule 13E-3s
shall comply in all material respects with all applicable requirements of law
and the rules and regulations of the SEC. Whenever any event occurs which is
required to be set forth in an



                                       85
<PAGE>

amendment or supplement to any Proxy Statement, Sellers and the Company each
shall promptly inform the other of such occurrences and Sellers shall prepare
(and, in the case of the Public McNeil Partnerships, file with the SEC) and mail
to the limited partners of the applicable Merging Partnership such amendment or
supplement to such Proxy Statement. Whenever any event occurs which is required
to be set forth in an amendment or supplement to any Schedule 13E-3, Sellers
shall promptly inform the Company of such occurrence, and Sellers and the
affiliates of the applicable Public McNeil Partnership shall file such amendment
or supplement. The Proxy Statements (at the respective dates thereof and at the
dates of the respective McNeil Limited Partner Meetings) and Schedule 13E-3s (at
the respective dates thereof) will not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading; provided, however, that the foregoing shall not apply
to the extent that any such untrue statement of a material fact or omission to
state a material fact was made by Sellers in reliance upon and in conformity
with information concerning the Company or any affiliates of the Company or
concerning the Transitory Partnerships or the Company LLCs furnished to Sellers
in writing by the Company specifically for use in any such Proxy Statements or
Schedule 13E-3s.

               (b) Each Merging Partnership shall, as soon as practicable
following the date of this Agreement, subject to the time periods set forth in
its organizational documents and in applicable laws, duly call, give notice of,
convene and hold a meeting of its limited partners (a "McNeil Limited Partner
Meeting") to be held at the earliest practicable date following the date the
applicable Proxy Statement is mailed to its limited partners for the purpose of
obtaining requisite approval by its limited partners of the Merger in respect of
such Merging Partnership, the MPLP Contributions with respect to such Merging
Partnership, the appointment of the applicable New GP LLC as the general partner
of such Merging Partnership and the other transactions contemplated by this
Agreement. Unless otherwise prohibited by law, each Merging Partnership and its




                                       86
<PAGE>

general partner shall be required to hold the McNeil Limited Partner Meeting
with respect to such Merging Partnership, regardless of whether the general
partner of such Merging Partnership has withdrawn, amended or modified its
recommendation that the limited partners of such Merging Partnership approve the
Merger in respect of such Merging Partnership, the MPLP Contributions with
respect to such Merging Partnership, the appointment of the applicable New GP
LLC as the general partner of such Merging Partnership and the other
transactions contemplated by this Agreement, unless this Agreement has been
terminated in respect of such Merging Partnership pursuant to the provisions of
Section 9.3 hereof. The general partner of each of the Merging Partnerships
shall recommend to the limited partners of such Merging Partnership approval of
the Merger in respect of such Merging Partnership, the MPLP Contributions with
respect to such Merging Partnership, the appointment of the applicable New GP
LLC as the successor general partner of such Merging Partnership and the other
transactions contemplated by this Agreement; provided, however, that prior to
the McNeil Limited Partner Meeting for such Merging Partnership (or any
adjournment thereof), the recommendation of the general partner of such Merging
Partnership may be withdrawn, modified or amended as a result of the
commencement or receipt of a proposal constituting a Superior Acquisition
Proposal with respect to such Merging Partnership, but only to the extent
expressly permitted under Section 7.2 hereof.

               (c) If on the date of the McNeil Limited Partner Meeting for a
Merging Partnership, such Merging Partnership has not received duly executed
proxies which, when added to the number of votes represented in person at the
meeting by persons who intend to vote to adopt this Agreement, will constitute a
sufficient number of votes to adopt this Agreement (and limited partners holding
greater than a majority of the outstanding LP Interests in such Merging
Partnership have not indicated their intention to vote against, and have not
submitted duly executed proxies voting against, the adoption of this Agreement),
then such Merging Partnership and its general partner shall recommend the
adjournment of its McNeil Limited Partner Meeting until the date ten (10) days
after the originally scheduled date of such McNeil Limited Partner Meeting.

implementation of any Acquisition Proposal or engage in any negotiations
concerning or provide any confidential information or data to, or have any
discussions with, any person relating to an Acquisition Proposal, or otherwise
facilitate any efforts to attempt to make or implement an Acquisition Proposal;

               (b) it shall immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Acquisition Proposal and shall take the necessary
steps to inform its officers, directors, employees or agents or representatives
(including any investment banker, attorney or accountant) retained by it of the
obligations undertaken in this Section 7.2; and

               (c) it shall notify the Company immediately if it receives any
such inquiries or proposals, or any requests for such information, or if any
such negotiations or discussions are sought to be initiated or continued with
it;

provided, however, that nothing contained in this Section 7.2: (i) shall
prohibit the general partner of any McNeil Partnership from furnishing
information to or entering into discussions or negotiations with, any person
that makes an unsolicited Acquisition Proposal for such McNeil Partnership, if,
and only to the extent that, (A) such general partner determines in good faith
that such unsolicited Acquisition Proposal could result in a Superior
Acquisition Proposal and that such action is required for such general partner
to comply with its duties to its limited partners imposed by law, (B) prior



                                       88

<PAGE>

any inquiries any such party may have concerning such quarterly and monthly

               (c) The Company shall, and shall cause its subsidiaries and
affiliates to, and shall cause each of their officers, employees, accountants,
counsel, financial advisors and other representatives to, hold any nonpublic

               (a) Subject to the terms and conditions provided in this
Agreement, Sellers, on the one hand, and the Company, on the other hand, shall

                                       91
<PAGE>

of the McNeil Partnerships and the other transactions contemplated by this
Agreement and the other Transaction Documents, such consents, approvals, orders
or authorizations to be in form reasonably satisfactory to Sellers and the
Company (it being acknowledged and agreed that nothing in this Section
7.4(a)(ii) shall affect or be deemed to amend or modify any provision of this
Agreement, including Sections 5.8, 8.1, 8.2 and 8.3 hereof); and (iii) without
the payment of any consideration therefor and without compromising their
respective rights and without incurring additional liabilities or obligations,
to take, or cause to be taken, all other action and do, or cause to be done, all
other things necessary, proper or appropriate to consummate and make effective
the transactions contemplated by this Agreement and the other Transaction
Documents (it being acknowledged and agreed that nothing in this Section
7.4(a)(iii) shall affect or be deemed to amend or modify any provision of this
Agreement, including Sections 5.8, 8.1, 8.2 and 8.3 hereof).

               (b) If at any time after the Effective Time any further action is
necessary or desirable to carry out the purpose of this Agreement, without the
payment of any consideration therefor and without compromising their respective
rights and without incurring additional liabilities or obligations, each Seller
and the Company shall, and each shall cause its respective affiliates and
subsidiaries to, take all such necessary action. Without the payment of any
consideration therefor and without compromising their respective rights and
without incurring additional liabilities or obligations, Sellers shall use their
reasonable efforts to cooperate with the Company in assisting the Company in its
efforts to correct or satisfy the items set forth on Schedule A to the Seller's
Task List. The Company shall indemnify and hold Sellers harmless for any and all
losses or damages (including reasonable attorneys' fees) that Sellers may suffer

<PAGE>

status of each Participating McNeil Partnership as a result of the transactions
contemplated hereby.

               Section 7.5   Public Announcements.

               (a) Sellers, on the one hand, and the Company, on the other hand,
shall consult with each other before the issuance by any of them or by any of
their affiliates, and shall provide each other the opportunity to review and
comment upon, any press release or other written public statements with respect
to the transactions contemplated by this Agreement and the other Transaction
Documents, and shall not, and shall cause their affiliates not to, issue any
such press release or make any such written public statement prior to such
consultation, except as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange. The parties agree that the initial press release to be issued with
respect to the transactions contemplated by this Agreement and the other
Transaction Documents shall be in the form mutually agreed to by the parties to
this Agreement prior to the execution of this Agreement.

               (b) Prior to the Closing, the Company shall not, and shall cause
its subsidiaries and affiliates not to, and shall cause each of their respective
partners, equity holders, members, officers, directors, managers, employees,
agents, accountants, counsel, financial advisors and other representatives not
to, publicly announce or disclose to any person (other than to senior management
of Sellers and, after notifying such lenders and prospective third party
property managers verbally of the confidential nature of such proposal or
intention, any existing or prospective lenders of the Company and any
prospective third party property managers for the Commercial Properties),
whether verbally or in writing, any proposal or intention to sell, transfer or
otherwise dispose of, in any manner (including by way of merger, consolidation,
exchange, business combination or any other transaction), directly or
indirectly, any of the McNeil Partnerships, Seller Subsidiaries, McNeil
Partnership Properties or assets of McREMI.

               Section 7.6   Benefit Plans and Other Employee
Arrangements.

                      (a)(i) Prior to the date of the mailing of the Proxy
        Statements for the Participating McNeil Partnerships (the "Proxy Mailing
        Date"), the Company shall provide a written list (the "Employment List")
        to Sellers of each employee of Sellers or any Seller Subsidiary to whom,
        as of the Effective Time, the Company shall cause Management LLC to
        offer employment (each such employee, a "Listed Employee") provided that
        such employee is still an employee of McREMI as of the Effective Time.
        The Listed Employees shall be comprised of two groups: one group shall
        be comprised of Property Employees for Multifamily Properties and shall
        be designated on the Employment List as the "Property Listed Employees"
        (the "Property Listed Employees") and the other group shall be comprised
        of Corporate Employees and shall be designated on the Employment List as
        the "Corporate Listed Employees" (the "Corporate Listed Employees"). The
        Property Listed Employees shall not constitute less than 75% of those
        employees of McREMI who, as of the Proxy Mailing Date, were Property
        Employees for Multifamily Properties with respect to the Participating
        McNeil Partnerships. The Corporate Listed Employees shall not constitute
        less than the Threshold Amount of those employees of McREMI, who, as of
        the Proxy Mailing Date, were Corporate Employees. For purposes of this
        Agreement, the "Threshold Amount" shall be an amount equal to the
        product determined by multiplying (A) the number of Corporate Employees
        as of the Proxy Mailing Date by (B) 0.5 by (C) a fraction, the numerator
        of which is the total number of McNeil Partnership Properties of
        the Participating McNeil Partnerships and their Seller Subsidiaries and
        the denominator of which is the total number of McNeil Partnership
        Properties of the McNeil Partnerships and their Seller Subsidiaries. The
        Company shall cause Management LLC to make such offers of employment on
        terms and conditions that are considered reasonable and customary in the
        real estate asset/property management industry as of the Closing Date,
        taking into account the geographic location of the employee



                                       94
<PAGE>

        to whom such offer of employment is being made. All such offers of
        employment may be made subject to drug testing, criminal background
        checks and credit checks.

                      (ii) The Company shall cause Management LLC to continue
        the employment of any Property Employee and any Corporate Employee who
        accepts such offer of employment for a period ending on December 31st of
        the calendar year following the calendar year in which the Closing
        occurs subject to termination for cause, resignation, retirement,
        performance reasons or business reasons. For purposes of this Agreement,
        any employee that accepts an offer of employment from the Company (or a
        subsidiary or affiliate of the Company) as of the Closing Date shall be
        referred to as an "Affected Employee."

                      (iii) In addition to continuing the workforce of McREMI in
        accordance with this Section 7.6, the Company shall cause Management
        LLC, for a period ending on December 31st of the calendar year following
        the calendar year in which the Closing occurs to continue utilizing the
        McREMI Assets listed on Annex H hereto to the extent those assets are
        transferred at Closing; provided, however, that, to the extent the
        Company reasonably determines that the continued utilization of a
        specific McREMI Asset is not supported by sound business practices,
        Management LLC may cease utilization of such asset and, if the Company
        reasonably determines that a substitution (which can be accomplished by
        way of purchasing, licensing, or leasing such substituted asset from a
        third party or an affiliate of the Company or developing such
        substituted asset in Management LLC) of such asset would be sound
        business practice, substitute a more appropriate asset in its stead;
        provided further, however, that if the Company determines not to
        substitute an asset for a discontinued asset it will not permit
        Management LLC to utilize an asset of Archon or its subsidiaries to
        provide the underlying function of the discontinued asset. In the event
        that Management LLC requires additional employees (because of any
        Affected Employee's termination, resignation, death, or



                                       95
<PAGE>

        retirement), such additional employees shall become employees of
        Management LLC.

                      (iv) Neither the Company (nor any subsidiary or affiliate
        of the Company) shall have any obligation to continue the employment of
        any Affected Employee that is not a Property Listed Employee or a
        Corporate Listed Employee for any specified period of time following the
        Closing.

               (b) At the Effective Time, McREMI shall terminate the employment
of each Affected Employee and shall cause the termination of employment of each
other employee of the Participating McNeil Partnerships and their respective
Seller Subsidiaries, and the employment of each Affected Employee by the
Company, Management LLC or their respective subsidiaries, as the case may be,
shall commence. The Company shall, or shall cause the appropriate subsidiary or
affiliate to, provide health, pension, retirement, disability and other employee
benefits to each Affected Employee on the same terms as, or on terms not less
favorable in the aggregate than, those provided to such Affected Employee
immediately prior to the Effective Time (such benefits, the "Buyer Plans").
Prior to the Effective Time, McREMI and each applicable Seller Subsidiary shall
cause the cancellation of all employment related agreements (including, without
limitation, all of the agreements listed on Schedule 4.11 of the Seller
Disclosure Letter) between it and any of its officers or directors and shall pay
all fees and costs related to such cancellation. Subject to the provisions of
this Section 7.6(b), the Company retains the right to amend or terminate any of
the Buyer Plans at any time.

               (c) As of the Effective Time, Affected Employees shall cease to
participate in the McREMI Plans and shall commence participation or shall become
eligible to participate in all Buyer Plans maintained after the Effective Time
in accordance with the second sentence of Section 7.6(b) hereof. McREMI shall
retain responsibility for all McREMI Plan claims incurred by Affected Employees
prior to the Effective Time regardless of when such claim is reported or made.
For purposes of this Section 7.6(c), a claim shall be deemed to have been
incurred when the medical or other service giving rise to the claim is




                                       96
<PAGE>

performed, except that disability claims shall be deemed to have been incurred
on the date the Affected Employee becomes disabled.

               (d) The Company shall, or shall cause its appropriate subsidiary
or affiliate to, give each Affected Employee full credit for up to five accrued
vacation days (in accordance with Item I of Note 18 to the applicable
Participating McNeil Partnership's Excess Cash Balance Schedule) and full credit
for purposes of eligibility, vesting, accruing subsequent vacation days and
determination of the level of benefits under each Buyer Plan (other than
incentive compensation plans) for such Affected Employee's service with McREMI
to the same extent recognized by such Seller or Seller Subsidiary immediately
prior to the Effective Time.

               (e) The Company shall, or shall cause its appropriate subsidiary
or affiliate to, waive all limitations as to preexisting conditions exclusions
and waiting periods with respect to participation and coverage requirements
applicable to each Affected Employee under any Buyer Plan (except for
preexisting conditions with respect to life insurance coverage), other than
limitations or waiting periods that are already in effect with respect to such
Affected Employee and that have not been satisfied as of the Effective Time
under any McREMI Plan maintained for the Affected Employee immediately prior to
the Effective Time.

               (f) Prior to the Effective Time, McREMI shall terminate any
401(k) Savings Plan of McREMI (each, a "McREMI 401(k) Savings Plan"), and each
employee who is a participant in any such terminated McREMI 401(k) Savings Plan
shall have the right to elect to receive a distribution of all of such
employee's account balance in such McREMI 401(k) Savings Plan (subject to, and
in accordance with, the provisions of such McREMI 401(k) Savings Plan and
applicable law). The Company shall, or shall cause its appropriate subsidiary or
Archon to, take any and all necessary action (subject to, and in accordance
with, the provisions of the Buyer Plan and applicable law) to cause the trustee
of a defined contribution plan of the Company (or its subsidiaries or Archon),
if requested to do so by a distributee who is an



                                       97
<PAGE>

Affected Employee, to accept the direct "roll over" of all or a portion of any
such distribution from any McREMI 401(k) Savings Plan.

               (g) Except as set forth in Section 7.6(h) hereof, McREMI shall be
liable for and be responsible for the administration of all claims, losses,
damages and expenses and other liabilities and obligations relating to or
arising out of all workers' compensation claims of Affected Employees pending as
of the Effective Time, or made after the Effective Time but relating to events
occurring prior to the Effective Time. The Company and its subsidiaries that
employ such Affected Employees shall be liable for and be responsible for the
administration of all claims, losses, damages and expenses and other liabilities
and obligations relating to or arising out of all workers' compensation claims
of Affected Employees made after the Effective Time and relating to events
occurring after the Effective Time.

               (h) McREMI shall give or arrange for written notice to be
provided to those employees (and their spouses) of McREMI who are not deemed
Affected Employees (the "Terminated Employees") of their right to elect to pay
continuation coverage under Section 4980B of the Code ("COBRA") in accordance
with applicable law. With respect to continuation coverage under COBRA required
to be provided by McREMI, the Company shall, if requested by McREMI, be
responsible following the Effective Time for administering on behalf of McREMI
(without cost to McREMI) the provision of such coverage for (A) all former
McREMI employees and their present or former dependents covered under COBRA at
the Effective Time and (B) all Terminated Employees and their present or former
dependents; provided, however, that the Company shall not be responsible for any
liabilities associated with COBRA benefit claims (other than liabilities
associated with the failure by the Company to pay-over to the appropriate
insurers the insurance premiums collected from COBRA participants).

               (i) Sellers shall, or shall cause their respective Seller
Subsidiaries to, take all necessary action to satisfy, or set aside sufficient
funds to



                                       98
<PAGE>

satisfy, all Severance Obligations for the Terminated Employees on or prior to
the Closing Date.

               Section 7.7   Ancillary Agreements.

               (a) Immediately prior to the Effective Time, each party hereto
shall, and shall cause its affiliates to, execute and deliver each Ancillary
Agreement to which such party or such party's affiliate is a party.

               (b) At the Closing, the Company shall, and the Company shall
cause Archon Group, L.P. ("Archon") to, execute and deliver the Portfolio
Advisory Agreement.

               Section 7.8   Support Agreements; Financing.

               (a) The Company shall, and shall cause the Company's subsidiaries
to, deliver at the Closing such agreements, instruments and other documents
(collectively, the "Replacement Support Agreements") as may be necessary to
assume all of Sellers' and their affiliates' (other than the Participating
McNeil Partnerships' and their subsidiaries') obligations as an indemnitor under
any and all Existing Support Agreements on terms no less favorable than those
under the Existing Support Agreements on the date hereof. The Company shall use
its reasonable efforts to ensure that the Replacement Support Agreements shall
contain provisions releasing Sellers and their pre-Closing affiliates (other
than the Participating McNeil Partnerships and their subsidiaries) from all
obligations thereunder. Without limiting the foregoing, the Company hereby
agrees to indemnify and hold harmless Sellers and their pre-Closing affiliates
(other than the Participating McNeil Partnerships and their subsidiaries) from
and against all obligations incurred under the Existing Support Agreements from
and after the Closing Date. MPLP, to the extent that the obligations of MPLP or
MII as an indemnitor under any Existing Support Agreement are not discharged
thereunder, agrees to indemnify and hold harmless the Company from and against
all obligations incurred by MPLP or MII as an indemnitor under any such Existing
Support Agreement prior to the Closing Date.

               (b) Without the payment of any consideration therefor (other than
as expressly contemplated by this



                                       99
<PAGE>

Agreement), without compromising any rights and without incurring additional
liabilities or obligations, Sellers shall take all necessary action (including
using their reasonable best efforts to obtain any third party consents) and the
Company shall, and shall cause its subsidiaries and affiliates to, take all
necessary action (including cooperating with Sellers to obtain any third party
consents), (i) to enable the Company to repay all Terminated Loans at the
Effective Time and (ii) to permit the Non-Terminated Loans to continue to remain
outstanding without penalty at and after the Effective Time until their
expiration or prepayment as indebtedness of the persons which incurred the
Non-Terminated Loans prior to the Effective Time (it being acknowledged and
agreed that nothing in this Section 7.8(b) shall affect or shall be deemed to
amend or modify any provision of this Agreement, including Sections 1.5, 8.1,
8.2 and 8.3 hereof).

               (c) Without limiting, amending or modifying any other provision
of this Agreement (including Sections 5.8, 8.1, 8.2 and 8.3 hereof), without the
payment of any consideration therefor, without compromising any rights and
without incurring additional liabilities or obligations, Sellers shall cooperate
with the Company to assist the Company in obtaining new financing in connection
with the Mergers and the other transactions contemplated by this Agreement and
the other Transaction Documents.

               Section 7.9   Fees and Expenses.

               (a) Except as expressly provided to the contrary in this
Agreement, whether or not the transactions contemplated by this Agreement or the
other Transaction Documents are consummated, all costs and expenses incurred in
connection with this Agreement and the other Transaction Documents including,
without limitation, the fees, expenses and disbursements of counsel, financial
advisors and accountants, shall be paid by the party incurring such costs and
expenses. Without limiting the generality of the foregoing, whether or not the
transactions contemplated by this Agreement or the other Transaction Documents
are consummated, McREMI agrees that it shall



                                      100
<PAGE>

be liable for the McREMI Transaction Expenses and each McNeil Partnership agrees
that it shall be liable for its Per Partnership Transaction Expenses; provided,
however, that a McNeil Partnership which becomes an Excluded McNeil Partnership
pursuant to Section 9.3(a) hereof shall not be liable for its Per Partnership
Transaction Expenses incurred following the date on which such McNeil
Partnership became an Excluded McNeil Partnership pursuant to Section 9.3(a)
hereof, and the Participating McNeil Partnerships shall share such expenses
ratably, based on their relative Partnership Percentages.

               (b) Any Assumption Fees, Prepayment Fees and Transaction Expenses
(including without limitation the McREMI Transaction Expenses) paid by the
Contributing Partners or any Seller (other than a McNeil Partnership) and any
fees, expenses and disbursements incurred and paid by the Contributing Partners
or any Seller (other than a McNeil Partnership) in connection with this
Agreement and the other Transaction Documents, subject to documentation and
approval (which shall not be unreasonably withheld or delayed) by the Board of
Managers of the Company (the "Board of Managers"), in an aggregate amount not to
exceed one-half of the aggregate amount of fees, expenses and disbursements
charged to the Company, its subsidiaries and affiliates by Sullivan & Cromwell
with respect to negotiating and documenting the transactions contemplated by
this Agreement and the other Transaction Documents, shall be treated as a
contribution in-kind to the Company (the "Capitalized McNeil Expenses") by MPLP
(or another designee of the Contributing Partners) in exchange for Company
Interests in accordance with Section 1.4 hereof.

               Section 7.10 Allocations. The Company and Sellers each covenant
(which covenant shall survive the Closing and the Effective Time), and the LLC
Agreement shall provide (until thereafter changed in accordance with the terms
of the LLC Agreement or applicable law), that the Allocations shall be binding
on Sellers and on the Company, its subsidiaries and affiliates and shall be
adhered to by Sellers and by the Company, its subsidiaries and affiliates for
the purposes of reporting the book and tax basis of the Company's assets.

               Section 7.11  Related Party Transactions.

               (a) Prior to the Effective Time, except as consented to in
writing by the Company (which consent shall not be unreasonably withheld or
delayed), or except as expressly provided for in this Agreement or the other
Transaction Documents, Sellers shall, and shall cause the Seller Subsidiaries
to, settle all Related Party Transactions with respect to the Participating
McNeil Partnerships in the ordinary course of business prior to the Effective
Time. In the event that any Related Party Transaction is not settled prior to
the Effective Time, such Related Party Transaction shall be cancelled as of the
Effective Time, and all fees and costs related to such cancellation shall be
taken into consideration in calculating the Excess Cash Balance of the
applicable Participating McNeil Partnerships in accordance with the Excess Cash
Balance Schedule.

               (b) Notwithstanding anything to the contrary in this Agreement,
if Summerhill is a Participating McNeil Partnership, the Company shall
contribute adequate cash to Summerhill to, and shall cause Summerhill to, repay
at the Effective Time (including all accrued but unpaid interest thereon through
to the Effective Time) the demand note, dated November 17, 1997, payable by
Summerhill to Robert A. McNeil and Carole J. McNeil (the "Summerhill Note"). The
parties hereto acknowledge and agree that in determining the Excess Cash Balance
of Summerhill, the Summerhill Note shall be deemed to be a current liability and

               Section 7.13  Estoppels.

               (a) Without the payment of any consideration therefor (other than
as expressly contemplated by this Agreement), without compromising any rights
and without incurring additional liabilities or obligations, Sellers shall use
their reasonable best efforts to obtain (i) the consent and estoppel
certificates and the consents (in each case, in the forms attached as exhibits
to this Agreement) specified in Section 8.2(d) hereof, (ii) the Estoppels (in
each case, in the forms attached as exhibits to this Agreement) from all
Commercial Tenants and from all lessors under each Ground Lease and (iii)
subject to Section 7.13(b) hereof, subordination, non-disturbance and attornment
agreements (the "SNDA Agreements") in the event that the Company requests in
writing that Sellers assist in obtaining SNDA Agreements.

               (b) In the event that the Company requests in writing that
Sellers assist in obtaining (i) any consents or estoppels specified in Section
8.2(d) hereof in a form other than the forms attached as Exhibits to this
Agreement ("Other Consents"), (ii) any Estoppels in a form other than the forms
attached as Exhibits to this Agreement ("Other Estoppels") or (iii) any SNDA

solicitation of the Other Consents, Other Estoppels and SNDA Agreements in
relation to the requisite dating of the consents, the consent and estoppel
certificates and the Estoppels attached to this Agreement and as to the content
of the Other Consents, Other Estoppels and SNDA Agreements. Nothing in this

the payment of any consideration therefor by any Seller, or shall require
compromising any rights of any Seller or shall require any Seller to incur

               Section 7.14  Harbour Club.

               (a) If (i) either MREF XXII or MREF XXIII or both are
Participating McNeil Partnerships and (ii) MREF XXV is an Excluded McNeil
Partnership, then MREF XXV hereby grants to the Company the right (which right
shall vest as of the Effective Time) to purchase the property known as Harbour
Club I Apartments, located at 49000 Denton Road, Belleville, Michigan, together
with the property known as the Harbour Club Golf Course (together, "Harbour Club
I"), at a price equal to eleven million nine hundred sixty thousand dollars
($11,960,000) (the "Option Price"). In the event that the Company desires to
exercise such right, the Company shall deliver a written notice to MREF XXV of
its election to do so promptly following the Effective Time, but in no event
later than the fifteenth business day following the Closing Date. In the event
that such notice has not been provided to MREF XXV by the Company by such
fifteenth business day, then, to the extent such right has vested in accordance
with this Section 7.14(a), such right shall irrevocably lapse and MREF XXV's
obligations in respect thereof shall be irrevocably discharged. The parties
hereto acknowledge and agree that the closing of the Company's purchase of
Harbour Club I must be completed within twenty (20) business days following the
Closing Date.

               (b) Notwithstanding anything to the contrary in this Agreement,
in the event that the Company exercises its right to purchase Harbour Club I in
accordance with Section 7.14(a) hereof, the Company shall pay at the closing of
such transaction any indebtedness outstanding which is secured by Harbour Club I
(including all accrued but unpaid interest thereon through to the date of such
closing) and all prepayment fees relating to such indebtedness on Harbour Club I
and the Option Price shall be reduced by the amount of such indebtedness (and
not the prepayment fees).

               (c) The obligations of the Company to effect the closing of the
Company's purchase of Harbour Club I pursuant to Section 7.14(a) hereof is
subject to the fulfillment (or waiver by the Company) on the date of such
closing of the following conditions: (i) title to Harbour Club I shall be free
and clear of all Property



                                      104
<PAGE>

Restrictions and Encumbrances other than the Permitted Restrictions and
Encumbrances and any matters arising after the Expiration Time (or, in the case
of the Survey Materials, after the Survey Materials Expiration Time) which (A)
would not preclude the continued use of Harbour Club I as it is being used as of
the date of this Agreement or (B) would not materially and adversely affect the
value of Harbour Club I as it is being used as of the date of this Agreement and
(ii) Lawyer's Title Insurance Company (or such other nationally recognized title
insurance company reasonably acceptable to Sellers and the Company) shall be
unconditionally obligated and prepared, subject to the payment of the applicable
title insurance premium and related charges at the Company's sole cost and
expense, to issue to or for the benefit of the Company and one or more of its
subsidiaries, a Title Policy (or the equivalent in the applicable jurisdiction)
for Harbour Club I in an amount requested by the Company, which shall be a
commercially reasonable amount, or, at the option of the Company, a "date-down"
to an existing policy of owner's title insurance. Such Title Policy shall be
issued in accordance with the Title Commitment for Harbour Club I. In the event
that one or both of the conditions set forth in the immediately preceding
clauses (i) and (ii) are not satisfied at the time of the closing of the
Company's purchase of Harbour Club I and the Company has not waived any such
unsatisfied condition prior to such time, MPLP and the Company agree to
negotiate in good faith a fair reduction in the Option Price to take into
account the matters with respect to which such conditions are not satisfied.

               (d) At and after the Effective Time, the owner of Harbour Club I
agrees, for so long as such owner shall continue to own Harbour Club I, to
manage, or cause to be managed, either or both of the Other Harbour Club
Properties, if so requested by the respective owners thereof, at market terms
and at market rates, pursuant to a property management agreement in a form
substantially comparable to that used for comparable properties, subject to such
owner obtaining the consent or approval of each person whose consent or approval
shall be required to a change in the management of such property. For purposes
of this Agreement, "Other Harbour Club Properties" means the property known as
the Harbour Club II Apartments and



                                      105
<PAGE>

the property known as the Harbour Club III Apartments, each located at 49000
Denton Road, Belleville, Michigan.

               Section 7.15  Material Encumbrances.

               (a) In the event that Other Items, or surveys that were received
by the Company after June 1, 1999, with respect to McNeil Partnership
Properties, in each case received prior to the Expiration Time (the Other Items
and such surveys, collectively, the "Survey Materials"), disclose any Property
Restrictions, Encumbrances or other matters affecting title to such McNeil
Partnership Property (other than Permitted Restrictions and Encumbrances) which
reasonably could preclude the continued use of such McNeil Partnership Property
as it is being used as of the date of this Agreement or reasonably could
materially and adversely affect the value of such McNeil Partnership Property as
it is being used as of the date of this Agreement (each, a "Material
Encumbrance") (it being understood and agreed that the absence of legal access
to a public right of way or utilities shall be a Material Encumbrance), the
Company shall promptly, and in no event later than 5:00 p.m., New York City
time, on July 16, 1999 (the "Expiration Time"), deliver a written notice (the
"Encumbrance Notice") to Sellers of such Material Encumbrance, which notice
shall describe in reasonable detail such Material Encumbrance and the manner in
which such Material Encumbrance reasonably could preclude the continued use of
such McNeil Partnership Property as it was being used as of the date of this
Agreement or reasonably could materially and adversely affect the value of such
McNeil Partnership Property as it was being used as of the date of this
Agreement, and the Company shall include a copy of the Survey Materials
disclosing such Material Encumbrance; provided, however, that the failure to
provide such information and description shall not vitiate the legal effect of
having sent such Encumbrance Notice if such Encumbrance Notice was otherwise
sent in good faith.

               (b) If the Company shall fail to deliver an Encumbrance Notice
prior to the Expiration Time with respect to one or more Material Encumbrances
on one or more McNeil Partnership Properties, then from and after the Expiration
Time (regardless of whether or not the



                                      106
<PAGE>

Company was aware of any such Material Encumbrance as of the Expiration Time,
and regardless of whether or not the Company has obtained all of the Other
Items), (i) each such Material Encumbrance shall automatically be deemed to be a
Permitted Restriction and Encumbrance for all purposes under this Agreement,
(ii) each such Material Encumbrance shall not be considered in determining
whether or not a Seller Material Adverse Effect has occurred for any and all
purposes under this Agreement (including Article VIII hereof) and (iii) the
Company shall be deemed to have waived all conditions to the Closing set forth
in Article VIII hereof relating to such Survey Materials (including, without
limitation, whether or not the representations and warranties contained in
Section 4.8 hereof were true and correct and whether or not the condition set
forth in Section 8.2(e) hereof has been fulfilled).

               Section 7.16 Additional Seller Tax Covenant. From the date of
this Agreement until the Closing Date, the McNeil Partnerships shall at all
times qualify, and Sellers shall cause any of the Seller Subsidiaries that have
been partnerships, joint ventures or disregarded entities or limited liability
companies since formation to continue to qualify, as partnerships or disregarded
entities for federal income tax purposes. From the date of this Agreement until
the Closing Date, the McNeil Partnerships shall not at any time become, and
Sellers shall not permit any Seller Subsidiaries that have been partnerships,
joint ventures or disregarded entities or limited liability companies since
formation to become, publicly traded partnerships within the meaning of Section
7704 of the Code or otherwise taxable as an association for federal income tax
purposes.

               Section 7.17 Title Deliveries. The Sellers shall arrange for the
delivery of the documents, certificates, affidavits and undertakings reasonably
required by the title insurer for the issuance of the title insurance coverage
contemplated by Section 8.2(e) hereof (provided that the Company, the
Participating McNeil Partnerships and their respective subsidiaries shall not be
liable directly or indirectly for such certificates, affidavits or
undertakings).

such case, is in effect and imposes restrictions on the Company or the

Adverse Effect (clauses (i) and (ii), collectively, an "Order"), and no
Governmental Entity shall have instituted any proceeding or threatened to
institute any proceeding seeking any such Order, and no other person shall have


                                      108

        forth in Article IV of this Agreement (other than the representations
        and warranties that are the subject of Section 8.2(a)(ii) below) shall
        be true and correct at and as of the Closing Date (each such
        representation and warranty shall be deemed to be amended as of the
        Closing Date (i) in accordance with Section 8.4 hereof and (ii) so as
        not to give effect to any materiality or Seller Material Adverse Effect
        qualifiers contained therein), as though made on and as of the Closing
        Date but immediately prior to the transfers of assets, rights and
        interests and the other transactions contemplated by Articles II and III
        of this Agreement, except to the extent any representation or warranty
        is expressly limited by its terms to a specific date, in which case such
        representation or warranty shall be true and correct at and as of such
        date; provided, however, that the condition set forth in this Section
        8.2(a) shall be deemed satisfied if the respects in which such
        representations and warranties (as each has been deemed amended as of
        the Closing Date) are not true and correct at and as of the Closing Date
        but immediately prior to the transfers of assets, rights and interests
        and the other transactions contemplated by Articles II and III of this
        Agreement, or at and as of such other date, would not constitute,
        individually or in the aggregate, a Seller Material Adverse Effect.



                                      110

        such representation and warranty shall be deemed to be amended as of the

        correct in all material respects (other than the representations and
        warranties having a materiality or Seller Material Adverse Effect
        qualifier, which representations and warranties shall be true and
        correct in all respects) at and as of the Closing Date, as though made

        Articles II and III of this Agreement, except to the extent any
        representation or warranty is expressly limited by its terms to a
        specific date, in which case such representation or warranty shall be

               (b) Performance of Obligations of Sellers. Sellers shall have
performed in all material respects all obligations required to be performed by
them under this Agreement at or prior to the Effective Time (other than
obligations with respect to Excluded McNeil Partnerships), including the

party.

               (c) Officer's Certificate. The Company shall have received a
certificate signed on behalf of Sellers by an executive officer thereof
certifying the accuracy of the statements set forth in Sections 8.2(a) and
8.2(b) hereof.

               (d)  Consents.

        consent and estoppel certificate attached as Exhibit A hereto or in the
        form(s) of a consent or estoppel certificate or both returned by the
        person from whom such consent and estoppel certificate is being sought
        pursuant to this Section 8.2(d)(i) provided such



                                      111
<PAGE>

        form(s) of consent or estoppel certificate is substantially comparable

        A hereto.

                      (ii) Sellers shall have obtained any consents or approvals
        which if not obtained would have, individually or in the aggregate, a

        Exhibit B hereto or in the form of the consent returned by the person
        whose consent is being sought pursuant to this Section 8.2(d)(ii)

               (e) Title. On the Closing Date, (i) title to each McNeil
Partnership Property owned by a Participating McNeil Partnership shall be free
and clear of all Encumbrances and Property Restrictions other than Permitted
Restrictions and Encumbrances and other than any matters disclosed after the
Expiration Time (other than the Survey Materials) which (A) would not reasonably
preclude the continued use of such McNeil Partnership Property as it is being
used as of the date of this Agreement or (B) would not reasonably materially and
adversely affect the value of such McNeil Partnership Property as it is being
used as of the date of this Agreement and (ii) Lawyer's Title Insurance
Corporation (or such other nationally recognized title insurance company
reasonably acceptable to Sellers and the Company) shall be unconditionally
obligated and prepared, subject to the payment of the applicable title insurance
premium and related charges at the Company's sole cost and expense, to issue to
or for the benefit of the Company and one or more of its subsidiaries, an
extended coverage ATLA owner's policy of title insurance effective as of the
Closing Date (the "Title Policies") (or the equivalent in the applicable
jurisdiction) for each McNeil Partnership Property owned by a Participating
McNeil Partnership in an amount requested by the Company, which amount shall be
commercially reasonable, or, at the option of the Company, a "date-down" to an
existing policy of owner's title insurance. Such Title Policies shall be issued
in accordance with the Title Commitments; provided, however, that,
notwithstanding anything to the contrary set forth



                                      112
<PAGE>

in this Agreement or in the Title Commitments, the title exceptions listed on
Schedule A to the Task List need not be omitted from the Title Policies and the
title company requirements listed on Schedule A to the Task List need not be
satisfied in determining whether or not this Section 8.2(e) has been satisfied.

               (f)  Estoppels.

                      (i) Sellers shall have received from tenants (which
        tenants shall include the tenants leasing space pursuant to the
        Commercial Leases listed on Schedule 8.2(f)(i) of the Seller Disclosure
        Letter) leasing at least seventy-five percent (75%) of the aggregate
        square footage leased pursuant to all Commercial Leases, a certificate
        (an "Estoppel"), addressed to the Company and its lender (as defined in
        the Estoppel attached as Exhibit D hereto), dated not more than sixty
        (60) days prior to the Closing Date, in either (A) the form of Estoppel
        attached as Exhibit D hereto or (B) the form of Estoppel returned by the
        tenant whose Estoppel is being sought pursuant to this Section 8.2(f)(i)
        provided such form of Estoppel is substantially comparable to the form
        of Estoppel attached as Exhibit D hereto. The Company hereby
        acknowledges and agrees that, in lieu of any one or more of such
        Estoppels, MPLP may deliver a landlord Estoppel provided that (A) such
        form of landlord Estoppel is in the form of Estoppel attached as Exhibit
        D hereto, (B) the landlord Estoppels delivered by MPLP pursuant to this
        Section 8.2(f)(i) shall not be given in respect of more than ten percent
        (10%) of the aggregate square footage leased pursuant to all Commercial
        Leases and (C) such landlord Estoppels delivered by MPLP shall not be
        delivered in respect of the Commercial Leases listed on Schedule

        lessor under a Ground Lease, addressed to the Company and its lender (as
        defined in the Estoppel attached as Exhibit E hereto), dated not more
        than sixty (60) days prior to the Closing Date in either (A) the form of
        Estoppel attached as



                                      113
<PAGE>

        Exhibit E hereto or (B) the form of Estoppel returned by the lessor
        whose Estoppel is being sought pursuant to this Section 8.2(f)(ii)
        provided such form of Estoppel is substantially comparable to the form
        of Estoppel attached as Exhibit E hereto.

               (g) Opinion Relating to the Pledge. The Company shall have
received an opinion from Skadden, Arps, Slate, Meagher & Flom LLP or other
counsel to Sellers reasonably acceptable to the Company, dated as of the Closing
Date, substantially in the form attached as Exhibit C hereto.

               (h) Percentage Reduction in NOI. The sum of the Net Operating
Incomes for each Participating McNeil Partnership for the twelve months ended on
the NOI Determination Date shall be greater than or equal to the product
determined by multiplying (i) 0.8723 by (ii) an amount equal to the sum of the
NOI Amounts for each Participating McNeil Partnership. For purposes of this
Agreement, the term "NOI Determination Date" means the last day of the most
recently completed fiscal month prior to the Closing Date.

               (i) Consummation of the Contributions. The transactions
contemplated by Sections 2.2 and 2.3(a) hereof shall have been consummated.

this Agreement relating to the Participating McNeil Partnerships which are to be
performed at or after the Effective Time are further subject to the fulfillment
(or waiver by each Seller) at or prior to the Effective Time of the following
conditions:

               (a) Representations and Warranties. The representations and
warranties of the Company set forth in Article V of this Agreement shall be true
and correct at and as of the Closing Date (each such representation and warranty
shall be deemed to be amended as of the Closing Date so as not to give effect to
any materiality



                                      114
<PAGE>

qualifiers contained therein), as though made on and as of the Closing Date but
immediately prior to the transfers of assets, rights and interests and the other
transactions contemplated by Articles II and III of this Agreement, except to
the extent any representation or warranty is expressly limited by its terms to a
specific date, in which case such representation or warranty shall be true and
correct at and as of such date; provided, however, that the condition set forth
in this Section 8.3(a) shall be deemed satisfied if the respects in which such
representations and warranties (as each has been deemed amended as of the
Closing Date) are not true and correct at and as of the Closing Date but
immediately prior to the transfers of assets, rights and interests and the other
transactions contemplated by Articles II and III of this Agreement, or at and as
of such other date, would not prevent the Company, any Company LLC or any
Transitory Partnership from consummating the transactions contemplated by this
Agreement and the other Transaction Documents.

               (b) Performance of Obligations of the Company. The Company shall
have performed in all material respects all obligations required to be performed
by it under this Agreement at or prior to the Effective Time (other than

8.5(c) hereof and the exercise (or lack of exercise) by the Company of its
rights under Sections 8.5(b) and 8.5(d) hereof shall not be the basis of any
suit, action or proceeding by any person against any party to this Agreement or
their respective affiliates, and shall not constitute a presumption that any
McNeil Partnership has, in fact, violated any representation, warranty, covenant
or



                                      118

agreement in this Agreement or that the conditions to Closing with respect to

that any information provided in any Schedule of the Seller Disclosure Letter is
considered disclosed in each and every other Schedule of the Seller Disclosure
Letter, and shall qualify the corresponding section of this Agreement, to the
extent it is clear from a reading of such information that such information is
applicable to such other section. Any disclosure in any Schedule of the Seller
Disclosure Letter of any contract, document, liability, default, breach,
violation, limitation, impediment or other matter, although the provision for
such disclosure may require such disclosure only if such contract, document,
liability, default, breach, violation, limitation, impediment or other matter be
"material," shall not be construed against any party to this Agreement, as an
assertion by such party, that any such contract, document, liability, default,
breach, violation, limitation, impediment or other matter is, in fact, material.

               Section 10.3 Interpretation. When a reference is made in this
Agreement to a section, article, paragraph, clause, annex or exhibit, such
reference shall be to a reference to this Agreement unless otherwise



                                      142

clearly indicated to the contrary. The descriptive article and section headings
herein are intended for convenience of reference only and are not intended to be
a part of or to affect the meaning or interpretation of this Agreement. Whenever
the words "transactions contemplated by this Agreement or the other Transaction
Documents" (or words of similar import) are used in this Agreement, they shall
be deemed not to include the Preferred Equity Financing or any other financing
contemplated by the Company or its affiliates either before, concurrently with
or following the Closing (it being understood that nothing in this sentence
shall affect or be deemed to amend or modify Section 8.2(d)(i) hereof). Whenever
the words "include", "includes" or "including" are used in this Agreement they
shall be deemed to be followed by the words "without limitation." The words
"hereof," "herein" and "herewith" and words of similar import shall, unless
otherwise stated, be construed to refer to this Agreement as a whole and not to
any particular provision of this Agreement. The meaning assigned to each term
used in this Agreement shall be equally applicable to both the singular and the
plural forms of such term, and words denoting any gender shall include all
genders. Where a word or phrase is defined herein, each of its other grammatical
forms shall have a corresponding meaning. The parties have participated jointly
in the negotiation and drafting of this Agreement and the other Transaction
Documents; consequently, in the event an ambiguity or question of intent or
interpretation arises, this Agreement and each of the other Transaction
Documents shall be construed as if drafted jointly by the parties thereto, and
no presumption or burden of proof shall arise favoring or disfavoring any party
by virtue of the authorship of any provision of this Agreement or of any of the
other Transaction Documents.

               Section 11.1 Nonsurvival of Representations, Warranties and
Covenants. Other than the covenants and agreements set forth in Sections 3.3,
3.5, 7.3(c) (except for rights and obligations thereunder with respect to




                                      143
<PAGE>

Participating McNeil Partnerships which shall not survive the Effective Time),
7.4(b), 7.6, 7.8(a), 7.9, 7.10, 7.11, 7.14, 9.4, 9.5 and 9.6 hereof and in this
Article XI, all of the representations, warranties, covenants, agreements and
undertakings set forth in this Agreement or in any instrument delivered pursuant
to this Agreement confirming the representations, warranties, covenants,
agreements and undertakings set forth in this Agreement shall terminate as of
the Effective Time and shall have no further force or effect. The parties hereto
hereby agree that, other than the representations and warranties contained in
Articles IV and V hereof, no representations or warranties are being made in
this Agreement by any party hereto.

               Section 11.2 Non-Recourse. The Company (on behalf of itself and
each Company Person) acknowledges and agrees that notwithstanding anything to
the contrary in this Agreement or under applicable law: (i) this Agreement shall
not create or be deemed to create or permit any liability or obligation on part
of any McNeil Person and no McNeil Person shall be bound or have any liability
hereunder (other than Robert A. McNeil solely in respect of Sections 2.2(a),
2.2(b) and 2.2(c)(ii) hereof); and (ii) the Company and each Company Person
shall look solely to the assets of Sellers for satisfaction of any
liability of Sellers under this Agreement, and neither the Company nor any
Company Person shall seek recourse or commence any action against any McNeil
Person or any McNeil Person's assets, for the performance or payment of any
obligation of Sellers (other than against Robert A. McNeil solely in respect of
his obligations under Sections 2.2(a), 2.2(b) and 2.2(c)(ii) hereof) under this
Agreement. This Agreement (except with respect to Sections 2.2(a), 2.2(b) and
2.2(c)(ii) hereof), is executed on behalf of certain Sellers by Robert A. McNeil
in his capacity, as the case may be, as a general partner, stockholder, officer
or director of such Seller, or as a general partner, stockholder, officer or
director of a Seller which is a stockholder or general partner of another
Seller, and not individually or personally. The Company (on behalf of itself and
each Company Person) has conducted its own independent review and analysis of
the business, operations, technology, assets, liabilities, results of
operations, financial condition and prospects of the business of Sellers and
acknowledges that Sellers



                                      144
<PAGE>

have provided the Company and the Company Persons with access to certain
personnel, properties, premises and books and records of such business for this
purpose. In entering into this Agreement, the Company has relied solely upon the
investigation and analysis of itself and the Company Persons and the specific
representations and warranties of Sellers set forth in Article IV of this
Agreement, and the Company (on behalf of itself and each Company Person)
acknowledges and agrees (i) that, except for the specific representations and
warranties of Sellers contained in Article IV hereof, no Seller or McNeil Person
makes or has made any representation or warranty, either express or implied, as
to the accuracy or completeness of any of the information (including any
projections, estimates or other forward-looking information) provided (including
in any management presentations, information memorandum, supplemental
information or other materials or information with respect to any of the above)
or otherwise made available to the Company or any Company Person, and (ii) that,
to the fullest extent permitted by law, none of the McNeil Persons shall have
any liability or responsibility whatsoever to the Company or any Company Person
on any basis (including in contract or tort, under federal or state securities
laws or otherwise) based upon any information provided or made available, or
statements made (or any omissions therefrom), to the Company or any Company
Person, including in respect of the specific representations and warranties set
forth in Article IV of this Agreement. Notwithstanding anything to the contrary
in this Section 11.2, nothing in this Section 11.2 shall be deemed to affect or
modify in any way the rights and obligations under the LLC Agreement or the
Indemnification Agreement of the parties thereto.

               Section 11.3 Amendment. This Agreement may be amended in writing
by the parties hereto at any time (i) before or after any requisite approvals of
the respective partners, limited partners or stockholders, as the case may be,
of each of the parties are obtained and (ii) prior to the filing of any of the
Merger Certificates with the Secretary of State of any of the states of
formation of the McNeil Partnerships set forth on Schedule 4.1(c) of the Seller
Disclosure Letter; provided, however, that, after the requisite approvals of the
limited partners of any McNeil Partnership are obtained, no such amendment,




                                      145
<PAGE>

modification or supplement shall be made which by law requires the further
approval of such limited partners without obtaining such further approval.

               Section 11.4 Extension; Waiver. At any time prior to the
Effective Time, the parties may in writing (i) extend the time for the
performance of any of the obligations or other acts of any other party, (ii)
waive any inaccuracies in the representations and warranties of any other party,
or (iii) waive compliance with any of the agreements or conditions of any other
party, in each case, contained in this Agreement, the other Transaction
Documents or in any document delivered pursuant to this Agreement or the other
Transaction Documents. Any agreement on the part of a party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of those rights.

               Section 11.5 Notices. All notices, requests, claims, demands and
other communications under this Agreement shall be in writing and shall be
delivered personally, sent by overnight courier (providing proof of delivery or

All notices shall be deemed given only when actually received. In no event shall

service of any writ, process or summons in any suit, action or other proceeding.

               Section 11.6 Counterparts. This Agreement may be executed in one
or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when one or more counterparts have been
signed by each of the parties and delivered to the other parties.

               Section 11.7 Entire Agreement; No Third Party Beneficiaries. This
Agreement (including the Seller Disclosure Letter), the other Transaction
Documents, the Confidentiality Agreement and the other agreements entered into
in connection with the Mergers and the other transactions contemplated by this
Agreement (i) constitute the entire agreement and supersede all prior agreements
and understandings, both written and verbal, between the



                                      147
<PAGE>

parties with respect to the subject matter thereof and (ii) are not intended to
confer upon any person (other than the parties to this Agreement and the
Contributing Partners) any rights or remedies whatsoever. Immediately following

the parties thereto shall terminate with respect to any Participating McNeil
Partnership and the Seller Subsidiaries of such Participating McNeil

               SECTION 11.8 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, REGARDLESS
OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS
OF LAWS THEREOF.

               Section 11.9 Assignment. Neither this Agreement nor any of the
rights, interests or obligations under this Agreement shall be assigned or
delegated, in whole or in part, by operation of law or otherwise by any of the
parties without the prior written consent of the other parties. Subject to the
preceding sentence, this Agreement shall be binding upon, inure to the benefit
of, and be enforceable by, the parties and their respective successors and
assigns.

               Section 11.10 Consent to Jurisdiction. Each of the parties hereto
irrevocably and unconditionally submits to the non-exclusive jurisdiction of the
United States District Court for the Southern District of New York or, if such
court will not accept jurisdiction, the Supreme Court of the State of New York
or any court of competent civil jurisdiction sitting in New York County, New
York. In any action, suit or other proceeding, each of the parties hereto
irrevocably and unconditionally waives and agrees not to assert by way of
motion, as a defense or otherwise any claims that it is not subject to the
jurisdiction of the above courts, that such action or suit is brought in an
inconvenient forum or that the venue of such action, suit or other proceeding is
improper. Each of the parties hereto also agrees that any final and unappealable
judgment against a party hereto in connection with any action, suit or other
proceeding shall be conclusive and binding on such party and that such award or
judgment may be enforced in any court of competent



                                      148
<PAGE>

jurisdiction, either within or outside of the United States. A certified or
exemplified copy of such award or judgment shall be conclusive evidence of the
fact and amount of such award or judgment.

               Section 11.11 Severability. Any term or provision of this
Agreement which is invalid or unenforceable in any jurisdiction shall, as to
that jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of
any of the terms or provisions of this Agreement in any other jurisdiction. If
any provision of this Agreement is so broad as to be unenforceable, the
provision shall be interpreted to be only so broad as is enforceable.

               Section 11.12 Arbitration. With respect to a determination of the
CPA Firm pursuant to Section 2.4(b) hereof and the determination of the
Financial Advisor with respect to a Higher Acquisition Proposal, each party
hereto agrees that such determination shall be final and binding upon such
party. Judgment on the determination may be entered in any court of competent
jurisdiction (within and outside the United States). In the event that any party
to this Agreement fails to comply, in the case of the determination of the CPA
Firm, with the procedures set forth in Section 2.4(b) hereof or the orders of
the CPA Firm or the determination of the CPA Firm, or, in the case of the
determination of the Financial Advisor, with the orders of the Financial Advisor
or the determination of the Financial Advisor and in either case, with this
Section 11.2, then such noncomplying party shall be liable for all costs and
expenses, including attorneys' fees, incurred by a party in its effort to obtain
either an order to compel compliance with such procedures or such orders, or an
enforcement of the determination, from a court of competent jurisdiction.

         WHEREAS, the Company was formed as a Delaware limited liability company
pursuant to the Certificate of Formation on June 17, 1999; and

         WHEREAS, the Parties hereto desire to continue the Company and to enter
into this Agreement, all as contemplated by the Master Agreement.

         NOW, THEREFORE, in order to carry out their intent as expressed above
and in consideration of the mutual agreements hereinafter contained and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, hereby covenant and
agree as follows:


                                   ARTICLE 1.

                                   DEFINITIONS

         1.1 Definitions. As used in this Agreement, the following terms shall
have the meanings set forth below:

         "Additional Capital Contributions" shall mean, with respect to any
Member, the amount of any cash contributions (including the Initial Working
Capital Contribution) and the value of any non-cash contributions made to the
Company by such Member in excess of such Member's Initial Capital Contribution.
Notwithstanding anything to the contrary contained herein, if Whitehall would
otherwise be entitled to receive a cash distribution of Net Cash Flow or Net
Proceeds from Capital Transactions pursuant to Section 8.1(b) or 8.1(c) from the
Company, Whitehall may elect to forego receipt of all or a portion of such
distribution and have the amount so foregone treated as an Additional Capital
Contribution in accordance with Section 6.4.

         "Affiliate" of any Person shall mean another Person that directly or
indirectly controls, is controlled by, or is under common control with, such
first Person.

between Whitehall and McNeil or, failing such an agreement within 10 days after
the appraisal procedure is commenced, (i) in the event that Whitehall and McNeil
have agreed upon an investment bank to serve as Appraiser, the value of the
non-cash consideration shall be determined by the Appraiser and (ii) in the
event that Whitehall and McNeil have requested that their respective investment
banks appoint a third investment bank to act as Appraiser, the value of the
non-cash consideration shall be determined by the Appraiser's determination of
the Independent Value. In the case of clause (ii), the investment bank appointed
by Whitehall shall make a determination of the value of the non-cash
consideration (the "Whitehall Value") and the investment bank appointed by
McNeil shall make a determination of the value of the non-cash consideration
(the "McNeil Value"). The Appraiser shall then make its own determination of the
value of the non-cash consideration (the "Independent Value"). If the
Independent Value is closer to the Whitehall Value, the Appraised Value shall be
equal to the Whitehall Value. If the Independent Value is closer to the McNeil
Value, the Appraised Value shall be equal to the McNeil Value. If the
Independent Value is equally distant to the McNeil Value and the Whitehall
Value, the Appraised Value shall be equal to the Independent Value. At the time
the Appraiser is appointed, the Members shall direct the Appraiser to determine
the Appraised Value within 30 days.

Members cannot agree on an investment bank to act as Appraiser within 10 days,
each Member shall appoint a nationally recognized investment bank and those two
investment banks shall appoint a third investment bank to act as Appraiser. In
no event shall the Appraiser be Goldman, Sachs & Co., PaineWebber Incorporated
or any of their respective Affiliates.

         "Approved Budget" shall mean the Annual Budget for the Budget Year in

specified date (calculated on a cumulative basis). The "Additional Amount" as of

and until each such Manager's successor has been elected and qualified and
Whitehall shall have the right to elect three Managers upon each annual election

cause, any Manager appointed by such Member and to appoint a successor Manager
to fill any vacancy caused by the removal, resignation, death or incapacity of
any Manager appointed by such Member. Each Member agrees to fill any such
vacancy as soon as practicable and agrees that it will use its best efforts to
fill any such vacancy within 30 days of such vacancy. Each Member agrees to give
the Company and the other Member prompt written notice of any appointment or
removal of any of its Managers.

              (c) Whitehall shall have the right to designate one of the five

meetings of the Board of Managers. The Chairman shall at all times be a Manager
of the Company. Except to preside over meetings of the Board of Managers, the
Chairman by virtue of such title shall have no other authority or power not
possessed by the other Managers. If no Chairman is designated by Whitehall, or
if at any meeting of the Board of Managers the Chairman is not present within
fifteen minutes after the time appointed for holding such meeting, any Whitehall
Manager present may choose one of their number to preside over such meeting as
chairman.

              (d) The Board of Managers may appoint the Officers of the Company,
which may consist of, among other officers, a President, a Secretary and a
Treasurer. The Board of Managers may also appoint such other Officers and agents
as it shall deem necessary or advisable. All Officers and agents shall hold
their offices for such terms and shall exercise such powers and perform such
duties as shall be determined from time to time by the Board of Managers. Any
two or more offices may be held by the same person. An Officer of the Company
shall hold office until his or her successor is duly appointed and qualified or
until his or her death, resignation or removal from office. Any Officer
appointed by the Board of Managers may be removed at any time, with or without
cause, by the affirmative vote of the majority of the Board of Managers. Any

Managers.

              (e) Any Manager designated pursuant to this Section 3.2 shall

Agreement and of a manager under the LLCA and shall be subject to the terms
hereof and thereof.

              (f) The Board of Managers shall have the right to delegate
authority to the Officers, provided that the Board of Managers does not delegate
the authority to make any decision regarding the matters described in Section
3.1(b)(i), 3.1(b)(v), 3.1(b)(xii), 3.1(b)(xiii), 3.1(b)(xv) or 3.8 or any matter
which by the terms of this Agreement requires a Super Majority Vote or the
consent of McNeil.

         3.3 Committees. The Board of Managers shall not have the power to

Subsidiaries for serving in the capacity as a Manager or as the Chairman of the
Board of Managers.

         3.5 Meetings of Managers.

              (a) The Board of Managers shall meet not less frequently than
quarterly, upon written notice duly given by any Whitehall Manager to all
Managers, provided that any failure to so meet shall not give rise to any
presumption or inference that the Members shall have any liability for the
obligations of the Company; and provided further that if a meeting has not been
called by a Whitehall Manager within 60 days after the last day of the
immediately preceding fiscal second quarter or fiscal year end, as the case may
be, any McNeil Manager may give notice to all Managers of such meeting.

              (b) Notwithstanding anything to the contrary contained herein or
in the LLCA, subject to the proviso in Section 3.5(a), the Board of Managers

may participate in any meeting of the Board of Managers by means of conference
telephone or similar communications equipment by means of which all individuals
participating in the meeting can hear and be heard by all other participants,
and such participation shall constitute presence in person at such meeting.

              (d) A waiver of notice signed by a Manager shall be deemed
equivalent to notice, whether signed before, at or after the meeting. Attendance
at a meeting shall constitute a waiver of notice.

              (e) Unless otherwise prohibited by law, any action required or
permitted to be taken by the Board of Managers may be taken without a meeting,
without prior notice and without a vote if a consent or consents in writing,

The resolution and the written consents thereto by the Managers shall be filed
with the minutes of the proceedings of the Board of Managers.

         3.6 Quorum. At all meetings of the Board of Managers three out of the

provided, however, that any Whitehall Manager shall have the right to represent
and vote the interests of one or both of the other Whitehall Managers and either
McNeil Manager shall have the right to represent and vote the interests of the
other McNeil Manager, in which event the absent Managers shall be deemed present
for purposes of constituting a quorum. In the event that at any meeting of the
Managers a quorum shall not be present, the Managers present may adjourn the
meeting from time to time until a quorum shall be present.

         3.7 Voting Requirements. When action is to be taken by vote of the
Board of Managers, each Manager shall be accorded one vote; provided, however,

Manager shall have the right to represent and vote the interests of the other
McNeil Manager. Except as provided in Section 3.8, all actions of the Board of
Managers must be approved by the affirmative vote of at least three of the five

Members hereby agrees that neither the Board of Managers nor the Company shall
take, and shall not permit any of the Company's Subsidiaries to take, any of the
following actions without the approval of at least four (4) of the five (5)
Managers (a "Super Majority Vote") (which approval shall not be delegable to any
Manager, any committee of the Board of Managers or any Officers of the Company,
notwithstanding any other provision of this Agreement or applicable law to the
contrary):

indirectly interested in or connected with any Person employed by the Company to
render or perform a service shall not prohibit the Company from employing such
Person on an arm's length basis and at market rates (including in respect of

designation and agrees to execute, certify, acknowledge, deliver, swear to, file
and record at the appropriate public offices such documents as may be deemed
necessary or appropriate to evidence such approval. To the extent and in the
manner provided by applicable Code sections and regulations thereunder, the Tax
Matters Member (a) shall furnish the name, address, profits interest and
taxpayer identification number of each Member to the IRS and (b) shall inform
each Member of administrative or judicial proceedings for the adjustment of

purposes. Each Member hereby reserves all rights under applicable law with
respect to the activities undertaken by the Tax Matters Member, including the
right to retain independent counsel of its choice at its expense. The Company
shall indemnify the Tax Matters Member for any liabilities incurred in such
capacity.

         4.8 Proposed Transactions After Five Years.

              (a) In the event of any Proposed Change of Control Transaction
that is proposed to be consummated after the fifth (5th) anniversary of the
Closing Date, then Whitehall shall give McNeil written notice of the Proposed
Change of Control Transaction and McNeil shall be "cashed-out" upon the
consummation of such Proposed Change of Control Transaction. In exchange for all
of the McNeil Interest, the holders of the McNeil Interest shall be paid in the
aggregate an amount in cash equal to the Full Post Lock-out Payment upon the
closing of such Proposed Change of Control Transaction.

              (b) In the event of a Proposed Company Transaction that is
proposed to be consummated after the fifth (5th) anniversary of the Closing Date
the following shall apply:

              (i) If any portion of the consideration to be received by the
     Members in connection with any Proposed Company Transaction shall be other
     than cash, the consideration to be received by the holders of the McNeil
     Interest shall be of the same type and shall have the same terms as the
     consideration received by Whitehall.

              (ii) Except as provided in Section 4.8(b)(iii), Whitehall shall
     determine the value of any non-cash consideration to be received by the
     Members in any Proposed

                                      -31-



<PAGE>



     Company Transaction and if Whitehall determines that the value of such
     non-cash consideration plus any cash consideration to be received by the
     holders of the McNeil Interest is sufficient to provide to the holders of
     the McNeil Interest a Full Post Lock-out Payment, the holders of the McNeil
     Interest shall have the right to either (i) exchange all of the McNeil
     Interest upon the closing of such Proposed Company Transaction for such
     cash and non-cash consideration having a value (using Whitehall's
     valuation) equal to the Full Post Lock-out Payment, or (ii) exchange all of
     the McNeil Interest upon the closing of such Proposed Company Transaction
     for cash in an amount equal to the Full Post Lock-out Payment. McNeil shall
     have the right to engage, at the sole expense of the holders of the McNeil
     Interest, an investment bank or other appraiser to assist the holders of
     the McNeil Interest in determining whether to take the non-cash
     consideration or the cash.

              (iii) If such Proposed Company Transaction involves non-cash
     consideration (other than publicly traded securities) and Whitehall
     determines that the value of the non-cash consideration plus any cash
     consideration to be received by the holders of the McNeil Interest is not
     sufficient to make the Full Post Lock-out Payment, McNeil shall have the
     right, at the Company's expense, to commence the process to determine the
     Appraised Value of such non-cash consideration as set forth in the
     definitions of "Appraiser" and "Appraisal Value" in Section 1.1. The
     holders of the McNeil Interest shall have the option, in McNeil's sole
     discretion, to exchange all of the McNeil Interest upon the closing of such
     Proposed Company Transaction for such cash and non-cash consideration
     having a value (using the Appraised Value) equal to the McNeil Portion or
     to receive cash in the amount equal to the McNeil Portion.

         4.9 McNeil's Right Prior to Bankruptcy Filing. Notwithstanding anything
to the contrary contained in this Agreement, none of the Company, the Members or
the Board of Managers shall commence, take any action to commence, or cause to
be commenced by the Company or by any one or more of the Company's Subsidiaries,
any Bankruptcy unless (i) at least thirty (30) days prior thereto, the Board of
Managers shall have given McNeil written notice of such contemplated
commencement of a Bankruptcy, (ii) the Board of Managers shall have given McNeil
the opportunity during such thirty (30) day period to make any Additional
Capital Contribution as the Board of Managers shall reasonably and in good faith
determine is necessary to prevent such commencement or action and (iii) prior to
the expiration of such thirty (30) day period, McNeil shall not have made such
Additional Capital Contribution.

         4.10 Refinancing after Five Years. If at any time following the fifth
(5th) anniversary of the Closing Date the Company elects to repay, refinance or
otherwise alter, modify or amend the terms of any indebtedness, including
without limitation any Loan Agreement, to which the Properties are subject, and
such repayment, refinancing or other alteration, modification or amendment would
result in McNeil's share of "nonrecourse liabilities" (within the meaning of
Treasury Regulation Section 1.752) and "qualified nonrecourse financing" (within
the meaning of Section 465 of the Code) being less than an amount equal to (x)
the Initial QNL Amount multiplied by (y) a fraction the numerator of which shall
equal the aggregate initial Book Value of all of the Properties owned by the
Company after such refinancing, repayment or alteration (excluding Commercial
Properties) and the denominator of which shall equal the aggregate


                                      -32-



<PAGE>



initial Book Values of all of the Properties owned by the Company as of the
Closing Date (excluding the Commercial Properties), then (i) such repayment,
refinancing or other alteration, modification or amendment shall be discussed at
a meeting of the Board of Managers prior to any action being taken to repay,
refinance or otherwise alter, modify or amend the terms of any indebtedness,
including without limitation any Loan Agreement, to which the Properties are
subject, and (ii) the Company shall allocate, to the extent allocable all (or
the maximum portion allocable under applicable laws) of the Company's
"nonrecourse liabilities" and "qualified nonrecourse financing" to McNeil
provided that such allocation does not and may not result in any adverse
economic effect on Whitehall at the time of such allocation or at any future
time, as the same may be determined by Whitehall in Whitehall's sole discretion.
Notwithstanding anything to the contrary contained in this Agreement, at no time
shall McNeil be allocated less than its Percentage Interest of "nonrecourse
liabilities" and "qualified nonrecourse financing". If at any time, McNeil's
share of "nonrecourse liabilities" or "qualified nonrecourse financing" is less
than the amount determined pursuant to the first sentence of this Section 4.10,
then, at the request of a McNeil Manager, the Board of Managers shall discuss
the matter, McNeil agreeing that the Company and the Board of Managers shall
have no obligation to take any action in connection therewith.

         4.11 Senior Indebtedness and Preferred Equity Financing. The Board of
Managers shall have the authority to obtain, on behalf of the Company and its
Subsidiaries, any or all of the Company's and its Subsidiaries' financing
(including Senior Indebtedness and Preferred Equity Financing) from Goldman,
Sachs & Co. and/or its Affiliates (as lender) at market rates and terms and/or
from any other non-affiliated lender as the Board of Managers in good faith
deems appropriate.

         4.12 Property Manager. The Property Manager will be responsible for
property management. For the Multifamily Properties, the Property Manager will
be Management LLC for the period ending on December 31st of the calendar year
following the calendar year in which the Closing occurs and thereafter may be
Management LLC or an appropriate third-party property management agent which may
include Archon. For the Commercial Properties, the Board of Managers will select
Management LLC as Property Manager or an appropriate third-party property
management agent which may include Archon. All property management services will
be performed on an arm's-length basis and at market fees.

         4.13 Binding Effect of Asset Allocations. The Asset Allocations shall
be binding on the Company and the Members and shall be adhered to by the Company
and the Members for the purposes of reporting the book and tax basis of the
Company Assets.

         4.14 Reservation of Rights. Notwithstanding anything to the contrary
contained in this Agreement, nothing in this Agreement shall (or shall be
construed to) constitute a waiver by any Member of its rights under applicable
law and its right to retain independent counsel of its choice at such Member's
expense.

         4.15 Taxation as a Partnership. The Members intend and shall take, or
shall cause the Company to take, any and all reasonable actions to ensure that
the Company shall be treated as a partnership for income tax purposes and that
any of the Subsidiaries of the Company that have


                                      -33-



<PAGE>



been partnerships, joint ventures, disregarded entities or limited liability
companies since formation shall continue to qualify, as partnerships or
disregarded entities for income tax purposes.

         4.16 Harbour Club Properties.

              (a) Each of the Members covenants and agrees to make an Additional
Capital Contribution to the Company in accordance with such Member's Percentage
Interest, determined immediately prior to the making by any Member of any
Additional Capital Contribution pursuant to this Section 4.16(a), to fund the
purchase price of Harbour Club Phase Four if the Company elects to purchase
Harbour Club Phase Four. The Additional Capital Contribution made by McNeil
pursuant to this Section 4.16(a) shall be included as part of the McNeil Class B
Investment. The Additional Capital Contribution made by Whitehall pursuant to
this Section 4.16(a) shall be included as part of the Whitehall Class A
Investment. The Company or one of its Subsidiaries will hold Harbour Club Phase
Four as a Company Asset until the Board of Managers decides to dispose of such
asset. If either Member shall fail to make its required Capital Contribution
pursuant to this Section 4.16(a), the other Member may purchase Harbour Club
Phase Four directly and not through the Company.

              (b) In the event that the Company exercises its option to purchase
Harbour Club Phase One, pursuant to Section 7.14 of the Master Agreement, each
of the Members covenants and agrees to make an Additional Capital Contribution
to the Company in accordance with such Member's Percentage Interest, determined
immediately prior to the making by any Member of any Additional Capital
Contribution pursuant to this Section 4.16(b), to fund the purchase price of
Harbour Club Phase One. The Additional Capital Contribution made by McNeil
pursuant to this Section 4.16(b) shall be included as part of the McNeil Class B
Investment. The Additional Capital Contribution made by Whitehall pursuant to
this Section 4.16(b) shall be included as part of the Whitehall Class A
Investment. The Company or one of its Subsidiaries will hold Harbour Club Phase
One as a Company Asset until the Board of Managers decides to dispose of such
asset. If either Member shall fail to make its required Capital Contribution
pursuant to this Section 4.16(b), the other Member may purchase Harbour Club
Phase One directly and not through the Company.

         4.17 Preferred Equity Financing. The Company shall, and shall cause its
Subsidiaries to, use reasonable efforts to achieve financing with respect to
those Properties that are security for Non-Terminated Loans by replacing each
such Non-Terminated Loan with mortgage or Preferred Equity Financing on
commercially reasonable terms when each such Non-Terminated Loan becomes
prepayable without any penalty.

statement showing allocations to the Members of taxable income, gains, losses,
deductions and credits, as prepared by such accountants (it being acknowledged
that the Board of Managers' obligations hereunder are not to guaranty timely
delivery of audits, tax returns or similar third-party work product). For each

                      CAPITAL CONTRIBUTIONS AND LIABILITIES

         6.1 Initial Capital Contributions and Initial Capital Accounts of the
Members.

              (a) Immediately prior to the Effective Time, MPLP was required to

Participating McNeil Partnerships, (iii) the limited partnership interests in
Fairfax held by MPLP at such time if Fairfax was a Participating McNeil

at such time if Summerhill was a Participating McNeil Partnership and (v) the

McNeil or an Affiliate of McNeil and may not be funded, in whole or in part, by
a third-party investor; provided, further, that any Whitehall Class B Investment
may only be funded by Whitehall or an Affiliate of Whitehall and may not be
funded in whole or in part, by a third party investor.

              (b) Immediately prior to the Effective Time, Whitehall was
required to contribute to the Company (i) cash in the amount of $_______________
[insert an amount equal to the Funding Amount (as defined in the Equity
Commitment Letter)] as required by the Equity Commitment Letter, and has also
contributed (ii) $___________ representing all of the costs incurred and paid by
Whitehall on behalf of the Company in connection with the negotiation,

               MEMBER                  INITIAL CAPITAL CONTRIBUTION
               ------                  ----------------------------

     Total                      $

              (iii) As of the Effective Time the McNeil Class A Investment, the

     Class A Investment and the Whitehall Class B Investment are in the amounts

          McNeil Class C Investment                         $
          Whitehall Class A Investment                      $
          Whitehall Class B Investment                      $

         6.2 Working Capital Contributions and Other Additional Capital
Contributions.

              (a) Whitehall shall make additional cash capital contributions to
the Company in an aggregate amount (the "Initial Working Capital Contribution")
equal to the difference determined by subtracting (x) the sum of the Net Working
Capital Amounts for each Participating McNeil Partnership from (y) the product
of $40,000,000 multiplied by the Value Fraction. The Initial Working Capital
Contribution shall be contributed to the capital of the Company by Whitehall
from time to time as the Board of Managers deems necessary in its reasonable
discretion to pay for Working Capital Expenses. All contributions made by
Whitehall on account of the Initial Working Capital Contribution shall be
included within the definition of Additional Capital Contributions.

              (b) After Whitehall has fully funded the Initial Working Capital
Contribution, Whitehall may, at any time or times, make in cash Additional
Capital Contributions to the Company that the Board of Managers determines are
necessary or desirable to conduct the business of the Company in the event
Working Capital Reserves and Recurring Replacement Reserves are not sufficient
to pay for such cost or expense.

              (c) Except as provided in Sections 4.9 and 4.16, McNeil shall have
no right or obligation to make any Additional Capital Contributions to the
Company.

              (d) Notwithstanding anything to the contrary in this Agreement, if
a Member shall guarantee any indebtedness of the Company, such Member shall not
receive any credit to its Capital Account as a result of such guarantee and such
guarantee shall not be considered to be


                                      -37-



<PAGE>



a Capital Contribution unless, and only to the extent that, such Member makes a
payment in respect of that guarantee and such payment is not immediately
reimbursed by the Company.

         6.3 Capital of the Company. Except as otherwise expressly provided
herein, no Member shall be entitled to withdraw or receive any interest or other
return on, or return of, all or any part of its Capital Contribution, or to
receive any property of the Company (other than cash) in return for its Capital
Contributions.

         6.4 Distributions as Working Capital Reserves. Notwithstanding anything
to the contrary contained herein, if Whitehall would otherwise be entitled to
receive a cash distribution of Net Cash Flow or Net Proceeds from Capital
Transactions pursuant to Section 8.1(b) or 8.1(c) from the Company, Whitehall
may elect to forego receipt of all or a portion of such distribution and have
the amount so foregone treated as part of the Initial Working Capital
Contribution (or, after the Initial Working Capital Contribution has been funded
in full, as an Additional Capital Contribution; provided the Board of Managers
shall have determined in good faith (by Majority Vote) that such Capital
Contribution is required for use by the Company within a reasonable period of
time following the date upon which such distribution of cash would otherwise
have been made to Whitehall. In such event Whitehall will be treated as if it
had (i) received distributions equal to the amount it would have received
pursuant to Section 8.1(b) or 8.1(c) had Whitehall not foregone such
distribution and (ii) made an Additional Capital Contribution in such amount
(any such Additional Capital Contribution shall first be treated as part of the
Initial Working Capital Contribution until the Initial Working Capital
Contribution has been fully funded).

         6.5 Failure to Fund the McNeil Cash Contribution. (a) If McNeil shall
fail to make the McNeil Cash Contribution in the full amount required pursuant
to the Master Agreement (the "Failed Contribution") at the Effective Time, then
Whitehall may, but shall not be obligated to, fund all or part of such Failed
Contribution. At any time after funding all or part of a Failed Contribution,
Whitehall may elect either of the following:

                  (i) Whitehall may at any time (even after first electing to
         proceed under paragraph (ii) below, but after termination of the
         Partner Loan) elect to treat the portion (the "Funded Portion") of the
         Failed Contribution funded by Whitehall as a Capital Contribution
         (which shall be deemed part of Whitehall's Initial Capital Contribution
         and the Whitehall Class A Investment) by Whitehall with the dilution of
         McNeil provided for in Section 6.5(b) below.

                  (ii) Whitehall may elect to treat the Funded Portion as a loan
         (a "Partner Loan") by Whitehall to McNeil, which Partner Loan shall be
         treated as (i) a demand loan made by Whitehall to McNeil (bearing
         interest at 20% per annum, compounded annually) followed by (ii) a
         Capital Contribution by McNeil to the Company. Any such Partner Loan
         (to the extent of unpaid principal and interest) shall be recourse only
         to the McNeil Class A Interest and shall be repaid directly by the
         Company on behalf of McNeil from amounts otherwise distributable to
         McNeil pursuant to Section 8.1 or 10.3 hereof. Any such distributions
         used to repay such Partner Loan shall be applied first to accrued but
         unpaid interest and then to principal of the Partner Loan. Whitehall
         may, at


                                      -38-



<PAGE>



         any time prior to the full repayment of such Partner Loan, elect to
         terminate such Partner Loan and have the McNeil Class A Investment,
         McNeil's Percentage Interest and, at the election of Whitehall,
         McNeil's Capital Account diluted as set forth in Section 6.5(b) below,
         with the amount of the entire outstanding principal and accrued but
         unpaid interest (as of the date of such termination) of the Partner
         Loan treated as the amount of the Funded Portion and not as a Capital
         Contribution of McNeil, and the McNeil Class A Investment, the
         Whitehall Class A Investment, the McNeil and Whitehall Percentage
         Interests and, at the election of Whitehall, the McNeil and Whitehall
         Capital Accounts, adjusted accordingly.

                  (b) If Whitehall elects to make a Capital Contribution for
         McNeil (instead of a Partner Loan) or elects to terminate a Partner
         Loan and have the provisions of this Section 6.5(b) apply then the
         adjustments set forth in clauses (i) and (ii) and, only upon the
         election of Whitehall, clause (iii) shall be made:

                           (i) The Percentage Interest of Whitehall shall be
                  increased so that it is equal to the percentage (rounded up to
                  the nearest one hundredth of one percent) obtained by dividing
                  (A) the sum of (1) all Capital Contributions made by Whitehall
                  other than the Funded Portion and (2) the product of (x) 2.0
                  and (y) the Funded Portion by (B) the sum of all Members'
                  Capital Contributions as of such date (including the Funded
                  Portion), and the Percentage Interest of McNeil shall be
                  decreased by the amount of the increase in Whitehall's
                  Percentage Interest.

                           (ii) The Whitehall Class A Investment shall be
                  increased by an amount equal to the product of (A) 2.0 and (B)
                  the Funded Portion and the McNeil Investment shall be reduced
                  by an amount equal to the Funded Portion; provided, however,
                  that this clause (ii) shall not cause an adjustment to the
                  Percentage Interests of Whitehall and McNeil which has already
                  been effected pursuant to Section 6.5(b)(i).

                           (iii) Whitehall's Capital Account shall be increased
                  as required under Section 7.1(b), and shall be further
                  increased by an amount equal to the Funded Portion; and

                            CAPITAL ACCOUNTS, PROFITS
                           AND LOSSES AND ALLOCATIONS

         7.1 Capital Accounts.

              (a) The Company shall establish and maintain a Capital Account for
each Member in accordance with federal income tax accounting principles. Each
Member's Capital Account as of the Effective Time initially will be equal to the
value of its Initial Capital Contribution.

              (b) The Capital Account of each Member shall be increased by (i)
the amount of any cash and the agreed Book Value of property (net of liabilities
encumbering the property) as of the date of contribution of any property
subsequently contributed as a capital contribution to the capital of the Company
by such Member, (ii) the amount of any Profits allocated to such Member and
(iii) such Member's pro rata share (determined in the same manner as such
Member's share of Profits pursuant to Section 7.2) of income of the Company that
is exempt from tax. The Capital Account of each Member shall be decreased by (i)
the amount of any Losses allocated to such Member, (ii) the amount of
distributions to such Member and (iii) such Member's pro rata share (determined
in the same manner as such Member's share of Losses pursuant to Section 7.2) of
any other expenditures of the Company that are not deductible in computing
Company Profits or Losses and which are not chargeable to capital account. In
all respects, the Member's Capital Accounts shall be determined in accordance
with the detailed capital accounting rules set forth in Treasury Regulations
Section 1.704-1(b)(2)(iv) and shall be adjusted upon the occurrence of certain
events as provided in Treasury Regulations Section 1.704-1(b)(2)(iv)(f).

              (c) A Transferee of all (or a portion) of an Interest shall
succeed to the Capital Account (or portion of the Capital Account) attributable
to the transferred Interest.

         7.2 Profits and Losses.

              (a) The profits and losses of the Company ("Profits" and "Losses")
shall be the net income or net loss (including capital gains and losses),
respectively, of the Company determined for each Fiscal Year in accordance with
the accounting method followed for federal income tax purposes except that in
computing Profits and Losses, all depreciation and cost recovery deductions
shall be deemed equal to Depreciation and gains or losses shall be determined
by reference to Book Value rather than tax basis.

              (b) Whenever a proportionate part of the Profits or Losses is
allocated to a Member, every item of income, gain, loss, deduction or credit
entering into the computation of such Profits or Losses or arising from the
transactions with respect to which such Profits or Losses were realized shall be
credited or charged, as the case may be, to such Member in the same proportion;
provided, however, that "recapture income", if any, shall be allocated to the
Members who were allocated the corresponding depreciation deductions.


                                      -40-

              (c) If any Member transfers all or any part of its Interest during
any Fiscal Year or its Interest is increased or decreased, Profits and Losses
attributable to such Interest for such Fiscal Year shall be apportioned between
the transferor and transferee or computed as to such Member, as the case may be,
ratably on a daily basis, provided in all events that any apportionment
described above shall be permissible under the Code and applicable regulations
thereunder.

              (d) For all purposes, including federal, state and local income
tax purposes, Profits shall be allocated in each Fiscal Year among all the
Members pursuant to this Section 7.2(d) for the current period (i) first, to the
holders of the Whitehall Class B Interest in an amount equal to the
distributions made pursuant to Sections 8.1(b)(i) and 8.1(c)(ii) and (ii)
thereafter, in proportion to the aggregate distributions of cash paid to such
Member in respect of such period. In no instance, however, shall McNeil or any
Affiliate of McNeil be allocated Profits in a given year greater than the cash
distributed to them during that year.

              (e) For all purposes, including federal, state and local income
tax purposes, Losses shall be allocated each Fiscal Year among all the Members
in accordance with their Percentage Interests.

              (f) Notwithstanding Sections 7.2(d) and (e) hereof:

                  (i) For federal income tax purposes but not for purposes of
     crediting or charging Capital Accounts, depreciation or gain or loss
     realized by the Company with respect to any property that was contributed
     to the Company or that was held by the Company at a time when the Book
     Value of the Company Assets was adjusted pursuant to the third sentence of
     Section 7.1(b) shall, in accordance with the "traditional method" under
     Section 704(c) of the Code and Treasury Regulations Sections
     1.704-1(b)(2)(iv)(d) and (f), be allocated among the Members in a manner
     which takes into account the differences between the adjusted basis for
     federal income tax purposes to the Company of its interest in such property
     and the fair market value of such interest at the time of its contribution
     or revaluation.

                  (ii) If there is a net decrease in the Minimum Gain of the
     Company during a taxable year (including any Minimum Gain attributable to
     Member-Funded Debt), each Member at the end of such year shall be
     allocated, prior to any other allocations required under this Article 7,
     items of gross income (including net gain) for such year (and, if
     necessary, for subsequent years) in the amount and proportions described in
     Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(4).

                  (iii) In the event any Member unexpectedly receives any
     adjustments, allocations or distributions described in Treasury Regulations
     Sections 1.704-(b)(2)(ii)(d)(4), (5) or (6), items of Company income and
     gain shall be specially allocated to each such Member in an amount and
     manner sufficient to eliminate, to the extent required by the Treasury
     Regulations, the deficit of such Member's Capital Account (as determined
     under Treasury Regulations Section 1.704-1) as quickly as possible,
     provided that an allocation pursuant to this subsection 7.2(f)(iii)


                                      -41-



<PAGE>



     shall be made only if and to the extent that such Member would have such
     Capital Account deficit after all other allocations provided for in Section
     7.2 have been tentatively made as if this subsection 7.2(f)(iii) were not
     in this Agreement.

                  (iv) In the event any Member has a deficit balance in such
     Member's Capital Account (as determined after crediting such Capital
     Account for any amounts that such Member is obligated to restore or is
     deemed obligated to restore pursuant to (a) any provision of this Agreement
     and (b) the penultimate sentences of Treasury Regulations Section
     1.704-(g)(1) and 1.704-2(i)(5), items of Company income and gain shall be
     specially allocated to such Member in an amount and manner sufficient to
     eliminate such deficit (as so determined) of such Member's Capital Account
     as quickly as possible; provided, however, that an allocation pursuant to
     this Section 7.2(f)(iv) shall be made only if and to the extent that such
     Member would have such Capital Account deficit (as so determined) after all
     other allocations provided for in Section 7.2 (other than Section
     7.2(f)(iii)) have been tentatively made as if this Section 7.2(f)(iv) were
     not in this Agreement.

                  (v) Notwithstanding the allocations provided for in
     sub-section (i) of this Section 7.2(f) and Sections 7.2(d) and (e), if
     there is a net increase in Minimum Gain of the Company during a taxable
     year of the Company that is attributable to Member-Funded Debt then first
     Depreciation, to the extent the increase in such Minimum Gain is allocable
     to depreciable property, and then a proportionate part of other deductions
     and expenditures described in Section 705(a)(2)(B) of the Code, shall be
     allocated to the lending or guaranteeing Member (and to joint lenders or
     guarantors in proportion to their relative obligations), provided that the
     total amount of deductions so allocated for any year shall not exceed the
     increase in Minimum Gain attributable to such Member-Funded Debt in such
     year.

                  (vi) Any special allocation under Sections 7.2(f)(ii) through
     (v) shall be taken into account in computing subsequent allocations of
     Profits and Losses of any item thereof pursuant to this Article 7 so that
     the net amount of any items so allocated and the Profits, Losses and all
     items thereof allocated to each Member pursuant to this Article 7 shall, to
     the extent permissible under Section 704(b) of the Code and the Treasury
     Regulations promulgated thereunder, be equal to the net amount that would
     have been allocated to each Member pursuant to this Article 7 if such
     special allocation had not occurred.

                  (vii) The Members intend that the provisions of this Article 7
     be interpreted, to the extent permissible under Section 704(b) of the Code
     and the Treasury Regulations promulgated thereunder, to produce liquidating
     distributions pursuant to Section 10.3(b) hereof that do not differ from
     the distributions that would have been made had liquidating distributions
     been controlled by Article 8 hereof, and the Board of Managers shall be
     entitled to the extent permissible under Section 704(b) of the Code and the
     Treasury Regulations promulgated thereunder, to specially allocate items of
     income, gain and loss to the Members to achieve this result.

              (g) No Member shall be responsible to restore or repay to the
Company or any other Member any deficit in such Member's Capital Account
existing at any time.

each of clauses (i) through (v), subject to Sections 9.1(c), 9.1(d), 9.2, 9.3
and 9.4. McNeil shall have no other right to make any Transfer of all or any
portion of its Interest. Any Transfer (including any pledge or hypothecation) of
the Pledged Interests shall be made explicitly subject to the Indemnification
Agreement.

              (c) Except as provided in Sections 9.1(a) and (b), all Transfers
are prohibited. Any purported Transfer in violation of this Article 9 shall be
void ab initio, and shall not bind the Company or the other Members, and the
Member whose Interest was directly or indirectly Transferred shall indemnify and
hold the Company and the other Members harmless from and against any federal,
state or local income taxes, or transfer taxes, including transfer gains taxes,
arising as a result of, or caused directly or indirectly by, such purported
Transfer.

              (d) Any Transferee desiring to make a further Transfer shall
become subject to all of the provisions of this Article 9 and of this Agreement
to the same extent and in the same manner as any Member desiring to make any
Transfer.

              (e) The giving of any consent to a Transfer by the Super Majority
Vote of the Board of Managers or by any Member in any one or more instances
shall not limit or waive the need for such consent in any other or subsequent
instance.

         9.2 Transfer Binding on Company.

              (a) No Transfer permitted to be made under this Agreement shall be
binding upon the Company, and no Transferee of all or any part of a Member's
Interest shall be admitted to the Company as a Member, unless and until:

                  (i) any consent to the Transfer required by this Agreement
     (including without limitation any Super Majority Vote) shall have been
     obtained;

                  (ii) in the case of a Transfer of a Member's Interest, a
     duplicate original of such instrument of Transfer, duly executed and
     acknowledged by the transferor, has been delivered to the Company, and such
     instrument evidences (1) the written acceptance by the Transferee of all of
     the terms and provisions of this Agreement, and (2) the Transferee's
     representation that such Transfer was made in accordance with all
     applicable laws and regulations;

                  (iii) in the case of a Transfer of a Member's Interest, the
     Board of Managers has entered such Transferee as a Member on the books and
     records of the Company, which the Board of Managers is hereby directed to
     do upon satisfaction of such requirements; and

                  (iv) in the case of a Transfer of a Member's Interest, such
     Transferee shall have paid all reasonable legal fees and filing costs in
     connection with the substitution as a Member.

              (b) Notwithstanding anything to the contrary contained in this
Agreement, no Transfer of all or a portion of an Interest shall be made, and the
Board of Managers shall have the right to prohibit and may refuse to accept any
Transfer, unless: (i) registration is not required under the Securities Act of
1933, as amended, in respect of such Transfer; (ii) such Transfer does not
violate any applicable federal or state securities, real estate syndication, or
comparable laws; (iii) such Transfer will not be subject to, or such Transfer,
when aggregated with prior Transfers


                                      -48-



<PAGE>



will not result in the imposition of, any state, city or local transfer taxes,
including, without limitation, any transfer gains taxes, unless such transferor
pays such taxes; and (iv) such Transfer will not cause the Company to be treated
as a "publicly-traded partnership" within the meaning of Section 7704 of the
Code. The Board of Managers may elect prior to any Transfer to require an
opinion of counsel with respect to any of the foregoing matters.

                  (c) Subject to Section 9.3, a Transferee who has become a
Member in accordance with this Section 9.2 has, to the extent of the transferred
Interest, all of the rights, powers and benefits of and is subject to the
restrictions and liabilities of a Member under this Agreement and the LLCA with
respect to such transferred Interest. Upon admission of a Transferee as a
Member, the transferor of the Interest so held by such new Member shall cease to
be a Member of the Company to the extent of such transferred Interest.

         9.3 Certain Limitations. Unless and until a Transferee is admitted as a
Member pursuant to Section 9.2, a Transferee of a Member's Interest in whole or
in part shall not be entitled to designate one or more Managers to serve on the
Board of Managers (to the extent such right has been Transferred to such
Transferee) or to become or to exercise the rights of a Member, including the
right to require any information or accounting of the Company's business or the
right to inspect the Company's books and records. Such Transferee shall only be
entitled to receive, to the extent of the Interest transferred to such
Transferee, the share of distributions and Profits and Losses, including
distributions with respect to the return of Capital Contributions, to which the
Transferee would otherwise be entitled in respect of the transferred Interest.
The transferor of such Interest shall have the right to designate one or more
Managers to serve on the Board of Managers (to the extent such transferor had
such right prior to such Transfer) until such Transferee is admitted to the
Company as a Member pursuant to Section 9.2 with respect to the Transferred
Interest (but only if such right to designate one or more Managers to the Board
of Managers was Transferred to such Transferee).

         9.4 Acceptance of Prior Acts. Any Transferee who becomes a Member in
accordance with Section 9.2, by so becoming a Member, accepts, ratifies and
agrees to be bound by all actions duly taken pursuant to the terms and
provisions of this Agreement by the Company prior to the date it became a Member
and, without limiting the generality of the foregoing, specifically ratifies and
approves all agreements and other instruments as may have been executed and
delivered on behalf of the Company prior to such date and which are in force and
effect on such date.

               DISSOLUTION; WINDING UP AND DISTRIBUTION OF ASSETS

         10.1 Dissolution. The Company shall be dissolved and its affairs shall
be wound up upon the first to occur of the following:

               (i) December 31, 2015;



                                      -49-



<PAGE>



               (ii) subject to Section 3.8, the written direction of the Board
          of Managers;

               (iii) the Bankruptcy, death, dissolution, expulsion, incapacity
          or withdrawal of any Member or the occurrence of any other event that
          terminates the continued membership of any Member, unless within one
          hundred eighty (180) days after such event the remaining Members agree
          in writing to continue the business of the Company, provided, however,
          that, notwithstanding the foregoing, no Member shall have the right to
          (i) withdraw or resign as a Member of the Company, (ii) redeem, or
          request redemption of, its Interest or any part thereof or (iii)
          dissolve itself voluntarily;

               (iv) any event that makes it unlawful for the Company's business
          to be continued; or

               (v) the entry of a decree of judicial dissolution under Section
          18-802 of the LLCA.

         10.2 Winding Up.

              (a) In the event of the dissolution of the Company pursuant to
Section 10.1, the Board of Managers shall wind up the Company's affairs;
provided, however, that a reasonable time shall be allowed for the orderly
liquidation of the Company and the satisfaction of all liabilities to creditors
so as to enable the Members to minimize the normal losses attendant upon a
liquidation. The Members shall continue to share Profits and Losses during
liquidation in the same proportion, as specified in Section 7.2 hereof, as
before liquidation. Each Member shall be furnished with a statement audited by
the Company's accountants that shall set forth the assets and liabilities of the
Company as of the date of dissolution. Each Member (and its Affiliates) shall
pay to the Company all amounts then owing by it (and them) to the Company).

              (b) Upon dissolution of the Company, Whitehall may, in the name
of, and for and on behalf of, the Company, prosecute and defend suits, whether
civil, criminal or administrative, settle and close the Company's business,
dispose of and convey the Company's property, discharge or make reasonable
provision for the Company's liabilities, and distribute to the Members in
accordance with Section 10.3 any remaining assets of the Company, all without
affecting or increasing any liability or obligation of the Members, including
the Member participating in the winding up of the Company's affairs and shall
comply with the provisions of Section 18-804(b) of the LLCA.

         10.3 Distribution of Assets. Upon the winding up of the Company, the
assets shall be distributed as follows:

               (a) to creditors of the Company, including Members who are
          creditors, to the extent permitted by law, in satisfaction of
          liabilities of the Company, whether by payment or by establishment of
          adequate reserves, other than liabilities for distributions to Members
          and former members under Section 18-601 or Section 18-604 of the LLCA;
          and


                                      -50-



<PAGE>



               (b) to the Members in accordance with their respective Capital
          Account balances after allocation of Profits and Losses for the period
          ending immediately prior to such distribution and after giving effect
          to all contributions, distributions and allocations for all periods.

For the purpose of making liquidating distributions required by this Section
10.3, the Board of Managers may determine whether to distribute all or any
portion of the Company Assets in-kind or to sell all or any portion of the
Company Assets and distribute the proceeds therefrom. To the extent that the
Board of Managers determines that all or any portion of the Company Assets shall
be sold, such Company Assets shall be sold as promptly as practicable, in a
commercially reasonable manner.

         10.4 Certificate of Cancellation. Within ninety (90) days following the
dissolution and the commencement of winding up of the Company, or at any time
there are no Members, certificates of cancellation shall be filed with the
Secretary of State of the State of Delaware under Section 18-203 of the LLCA.

         10.5 Claims of the Members. The Members shall look solely to the
Company Assets for the return of their Capital Contributions, and if the Company
Assets remaining after payment of or due provision for all debts, liabilities
and obligations of the Company are insufficient to return such Capital
Contributions, the Members shall have no recourse against the Company or any
other Member or any other Person. No Member with a negative balance in such
Member's Capital Account shall have any obligation to the Company or to the
other Members or to any creditor or other Person to restore such negative
balance upon dissolution or termination of the Company or otherwise.


                                   ARTICLE 11.

                                   AMENDMENTS

execute, acknowledge, deliver, file and record such further certificates,
amendments, instruments and documents, and to do all such other acts and things,
as may be required by law or as, in the reasonable judgment of the Board of
Managers, may be necessary or advisable to carry out the intent and purpose of
this Agreement.

         12.2 Notices. Unless otherwise specified in this Agreement, all
notices, demands, elections, requests or other communications that any party to
this Agreement may desire or be required to give hereunder shall be in writing
and shall be given by hand by depositing the same in the United States mail,
first class postage prepaid, certified mail, return receipt requested, or by a
recognized overnight courier service providing confirmation of delivery, to the

designated by the Board of Managers) upon written notice to all of the Members.
All notices given pursuant to this Section 12.2 shall be deemed to have been
given (i) if delivered by hand on the date of delivery or on the date delivery
was refused by the addressee or (ii) if delivered by United States mail or by
overnight courier, on the date of delivery as established by the return receipt
or courier service confirmation (or the date on which the return receipt or
courier service confirms that acceptance of delivery was refused by the
addressee). Except as specified in Section 2.6, in no event shall the provision
of notice in accordance with this Section 12.2 constitute notice for service of
any writ, process or summons in any suit, action or other proceeding.

         12.3 Headings and Captions. All headings and captions contained in this
Agreement and the table of contents hereto are inserted for convenience only and
shall not be deemed a part of this Agreement.

         12.4 Variance of Pronouns. All pronouns and all variations thereof
shall be deemed to refer to the masculine, feminine or neuter, singular or
plural, as the identity of the Person or entity may require.

         12.5 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original and all of which, when
taken together, shall constitute one Agreement.

         12.6 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

         12.7 WAIVER OF JURY TRIAL. EACH OF THE MEMBERS (ON BEHALF OF ITSELF,
ITS AFFILIATES, AND THE HOLDERS OF INDIRECT AND DIRECT BENEFICIAL INTERESTS IN
ITSELF) AND THE COMPANY, HAVING CAREFULLY CONSIDERED THE ISSUE, AND HAVING
SOUGHT AND OBTAINED THE ADVICE OF COUNSEL, KNOWINGLY, INTENTIONALLY AND
IRREVOCABLY WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY CLAIM OR
PROCEEDING RELATED TO OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY.

         12.8 Consent to Jurisdiction. Each Member and the Company hereby
irrevocably consents and agrees, for the benefit of each Member, that any legal
action, suit or proceeding against it with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with
this Agreement and with respect to the enforcement, modification, vacation or


                                      -52-



<PAGE>



correction of an award rendered in an arbitration proceeding may be brought in
any federal or state court located in New York City (each a "New York Court"),
and hereby irrevocably accepts and submits to the exclusive jurisdiction of each
such New York Court, as the case may be, with respect to any such action, suit
or proceeding. Each Member and the Company hereto waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid
actions, suits or proceedings brought in any such New York Court and hereby
further waives and agrees not to plead or claim in any such New York Court that
any such action, suit or proceeding brought therein has been brought in an
inconvenient forum.

         12.9 Specific Performance. Each Member and the Company recognizes and
agrees that if for any reason any of the provisions of this Agreement are not
performed in accordance with their specific terms or are otherwise breached,
immediate and irreparable harm or injury would be caused for which money damages
would not be an adequate remedy. Accordingly, each Member and the Company agrees
that, in addition to any other available remedies, each Member shall be entitled
to an injunction restraining any violation or threatened violation of the
provisions of this Agreement without the necessity of posting a bond or other
form of security. In the event that any action should be brought in equity to
enforce the provisions of this Agreement, no party will allege, and each party
hereby waives the defense, that there is an adequate remedy at law.

         12.10 Partition. The Members hereby agree that no Member nor any
successor-in-interest to any Member shall have the right to have the Company
Assets partitioned, or to file a complaint or institute any proceeding at law or
in equity to have the Company Assets partitioned, and each Member, on behalf of
himself, his successors, representatives, heirs and assigns, hereby waives any
such right.

         12.11 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

         12.12 Successors and Assigns. This Agreement shall be binding upon the
Members and their respective successors, executors, administrators, legal
representatives, heirs, legal assigns and assigns permitted hereunder and shall
inure to the benefit of the Members, and, except as otherwise provided herein,
their respective successors, executors, administrators, legal representatives,
heirs, legal assigns and assigns permitted hereunder. No Person other than the
Members and their respective successors, executors, administrators, legal
representatives, heirs, legal assigns and permitted assigns shall have any
rights or claims under this Agreement.

         12.13 Entire Agreement. This Agreement supersedes all prior agreements
among the parties with respect to the subject matter hereof and contains the
entire Agreement among the parties with respect to such subject matter.


                                      -53-



<PAGE>



         12.14 Waivers. No waiver of any provision hereof by any party hereto
shall be deemed a waiver by any other party nor shall any such waiver by any
party be deemed a continuing waiver of any matter by such party.

         12.15 Maintenance as a Separate Entity. The Company shall maintain
books and records and bank accounts separate from those of its Affiliates (other
than the Company's Subsidiaries); shall at all times hold itself out to the
public as a legal entity separate and distinct from any of its Affiliates (other
than the Company's Subsidiaries) (including in its operating activities, in
entering into any contract, in preparing its financial statements, and on its
stationery and any signs it posts), and shall cause its Affiliates (other than
the Company's Subsidiaries) to do the same and to conduct business with it on an
arm's-length basis; shall not commingle its assets with assets of any of its
Affiliates (other than the Company's Subsidiaries); shall not guarantee any
obligation of any of its Affiliates (other than the Company's Subsidiaries);
shall cause its business to be carried on by the Board of Managers; and shall
keep minutes of all meetings of the Members.

         12.16 Confidentiality.


              (a) The Members agree not to disclose or permit the disclosure of
any of the terms of this Agreement or of any other confidential, non-public or
proprietary information relating to the Company, the Company's Subsidiaries, any
Property or the business of the Company (collectively, "Confidential
Information"), provided that such disclosure may be made (i) to any Person who
is a partner, officer, director or employee of such Member or counsel to or
accountants of such Member solely for their use and on a need-to-know basis,
provided that such Persons are notified of the Members' confidentiality
obligations hereunder, (ii) with the prior written consent of Whitehall, (iii)
subject to Section 12.16(b), pursuant to a subpoena or order issued by a court,
arbitrator or governmental body, agency or official, (iv) to any lender
providing financing to the Company, or (v) if in the opinion of counsel to the
Member seeking to disclose such Confidential Information, such disclosure is
required under the federal securities laws or the rules of regulation of any
relevant exchange.

              (b) In the event that a Member shall receive a request to disclose
any Confidential Information under a subpoena or order, such Member shall (i)
promptly notify the other Members thereof, (ii) consult with the Board of
Managers on the advisability of taking steps to resist or narrow such request
and (iii) if disclosure is required or deemed advisable by the Board of
Managers, cooperate with the Board of Managers in any attempt it may make to
obtain an order or other assurance that confidential treatment will be accorded
the Confidential Information that is disclosed. In the event such Member is
compelled to disclose such Confidential Information, such Member shall use all
reasonable efforts to cause disclosure only of such minimal amount of
Confidential Information as is required to deemed advisable to be so disclosed.

              (c) Except to satisfy requirements of law and only to the extent
of such requirements, no Member shall issue or publish any press release,
tombstone or other public communication about the formation or existence of the
Company without the express written consent of the other Members.

         12.17 No Third Party Beneficiaries. This Agreement is not intended and
shall not be construed as granting any rights, benefits or privileges to any
Person not a party to this Agreement. Without limiting the generality of the
foregoing, no creditor of the Company, or of any Member shall have any right
whatsoever to require any Member to contribute capital to the Company.

         12.18 Power of Attorney. Each Member does hereby irrevocably constitute
and appoint the Board of Managers with full power of substitution, as its true
and lawful attorney, in its name, place and stead, to execute, acknowledge,
swear to, deliver, record and file, as appropriate and in accordance with this
Agreement (i) all amendments to the original Certificate of Formation required
or permitted by law or the provisions of this Agreement and (ii) all
certificates and other ministerial instruments requiring execution by the
Members or any of them and deemed necessary or advisable by the Board of
Managers to qualify or continue the Company as a company wherein the members
have limited liability in the jurisdictions where the Company may be conducting
its operations.

         12.19 Construction of this Agreement. The parties have participated
jointly in the negotiation and drafting of this Agreement. Consequently, in the
event an ambiguity or question of intent or interpretation arises, this
Agreement shall be construed as if drafted jointly by the parties thereto, and
no presumption or burden of proof shall arise favoring or disfavoring any party
by virtue of the authorship of any provision of this Agreement.

         12.20 Non-Recourse.

              (a) Whitehall (on behalf of itself and the other Company Persons)
acknowledges and agrees that notwithstanding anything to the contrary in this
Agreement or under applicable law: (i) this Agreement shall not create or be
deemed to create or permit any liability or obligation on the part of any McNeil
Person, and no McNeil Person shall be bound or have any liability hereunder; and
(ii) any and all Company Persons shall look solely to the assets of McNeil for
satisfaction of any liability of McNeil under this Agreement, and no Company
Person shall seek recourse or commence any action against any McNeil Person's
assets, for the performance or payment of any obligation of McNeil under this
Agreement. Whitehall (on behalf of itself and the other Company Persons)
acknowledges and agrees that the Company Persons have conducted their own
independent review and analysis of the business, operations, technology, assets,
liabilities, results of operations, financial condition and prospects of the
business of the McNeil Partnerships and acknowledge that they have received
access to certain personnel, properties, premises and books and records of such
business for this purpose. In entering into this Agreement, Whitehall has relied
solely upon its own investigation and analysis and the specific representations
and warranties of McNeil made in this Agreement, and (i) acknowledges that,
except for the specific representations and warranties of McNeil contained in
this Agreement, neither McNeil nor any other McNeil Person makes or has made any
representation or warranty, either express or implied, as to the accuracy or
completeness of any of the information (including any projections, estimates or
other forward-looking information) provided (including in any management
presentations, information memorandum, supplemental information or other
materials or information with respect to any of the above) or otherwise made
available to Company Persons in connection with the transactions contemplated


                                      -55-



<PAGE>



by this Agreement and (ii) agrees, to the fullest extent permitted by law, that:
(i) none of the McNeil Persons shall have any liability or responsibility
whatsoever to any Company Person under this Agreement on any basis (including in
contract or tort, under federal or state securities laws or otherwise) based
upon any information provided or made available, or statements made (or any
omissions therefrom), to any Company Person in connection with the transactions
contemplated by this Agreement; and (2) that McNeil shall not have any liability
or responsibility whatsoever to any Company Person under this Agreement on any
basis (including in contract or tort, under federal or state securities laws or
otherwise (other than fraud or willful misrepresentation)) based upon any
information provided or made available, or statements made (or any omissions
therefrom), to any Company Person in connection with the transactions
contemplated by this Agreement, except as and only to the extent expressly set
forth in this Agreement and subject to any limitations and restrictions
contained in this Agreement.

              (b) Notwithstanding anything to the contrary in Section 12.20(a),
nothing in Section 12.20(a) shall be deemed to affect or modify in any way the
rights and obligations under the Master Agreement and the Indemnification
Agreement of the parties thereto.

         12.21 Setoff. Whitehall acknowledges and agrees (on behalf of itself
and each other Company Person) that no Company Person shall have any right
hereunder or pursuant to Law to offset or retain any amounts due or owing by any
McNeil Person against any amounts due or owing (or to become due or owing) to
any Company Person under any other agreement, contract or understanding
(including, without limitation, the Master Agreement); provided, however, that
nothing in this Section 12.21 shall be deemed to affect or modify in any way the
rights and obligations under the Indemnification Agreement of the parties
thereto.

         12.22 Arbitration. With respect to a determination of the Appraised
Value by the Appraiser in accordance with the terms of this Agreement, each
Member agrees that the determination of the Appraised Value by the Appraiser
shall be final and binding upon such party. Judgment on the determination may be
entered in any court of competent jurisdiction (within and outside the United
States). In the event that any Member fails to comply with the procedures set
forth in this Agreement relating to the determination of the Appraised Value, or
this Section 12.22, then such noncomplying Member shall be liable for all costs
and expenses, including attorneys' fees, incurred by a party in its effort to
obtain either an order to compel compliance with such procedures or such
orders, or an enforcement of the determination, from a court of competent
jurisdiction.
