On June 24, 1999, McNeil Real Estate Fund IX, Ltd. (the  "Partnership"),  McNeil
Real Estate Fund X, Ltd.,  McNeil Real Estate Fund XI, Ltd.,  McNeil Real Estate
Fund XII, Ltd.,  McNeil Real Estate Fund XIV, Ltd.,  McNeil Real Estate Fund XV,
Ltd.,  McNeil  Real  Estate Fund XX,  L.P.,  McNeil Real Estate Fund XXI,  L.P.,
McNeil Real Estate Fund XXII, L.P., McNeil Real Estate Fund XXIII,  L.P., McNeil

Associates,  L.P., McNeil Midwest  Properties I, L.P., Regency North Associates,
L.P., Fairfax Associates II, Ltd. ("Fairfax"), McNeil Summerhill I, L.P ("Summer
hill" and, collectively, the "McNeil Partnerships"),  McNeil Partners, L.P., the
general partner of the Partnership (the "General  Partner"),  McNeil  Investors,
Inc., McNeil Real Estate Management,  Inc. ("McREMI"),  McNeil Summerhill,  Inc.
and Robert A.  McNeil  entered  into a  definitive  acquisition  agreement  (the
"Master  Agreement")  with  WXI/McN  Realty  L.L.C.  ("Newco"),  an affiliate of
Whitehall  Street Real Estate Limited  Partnership XI, a real estate  investment
fund managed by Goldman,  Sachs & Co., whereby Newco and its  subsidiaries  will
acquire the McNeil  Partnerships.  The Master Agreement provides that the McNeil
Partnerships (other than Fairfax and Summerhill which are wholly-owned by Robert
A. McNeil and related  parties) will be merged with  subsidiaries of Newco.  The
Master Agreement also provides for the acquisition by Newco and its subsidiaries
of the general  partnership  interests  and  limited  partnership  interests  in
Fairfax and Summerhill and the assets of McREMI. The aggregate  consideration in
the  transaction,  including  the  assumption  or prepayment of all  outstanding
mortgage debt of the McNeil Partnerships, is $644,439,803.

Pursuant  to the terms of the Master  Agreement,  the  limited  partners  in the
Partnership  will  receive  cash on the  closing  date of the  transaction  (the
"Closing  Date")  in  exchange  for  their  limited  partnership  interests.  In
addition,  the  Partnership  will declare a special  distribution to its limited
partners  on the Closing  Date equal to its then  positive  net working  capital
balance, if any. The estimated  aggregate  consideration and net working capital
distribution  to be  received  per unit of limited  partnership  interest in the
Partnership is currently estimated as $424.

On  the  Closing  Date,  McNeil  Partners,  L.P.,  the  general  partner  of the
Partnership,  will  receive  an equity  interest  in Newco in  exchange  for its
contribution  to  Newco  of the  general  partnership  interests  in the  McNeil
Partnerships,  the limited  partnership  interests in Fairfax and Summerhill and
the assets of McREMI.


<PAGE>
The  Partnership's  participation  in the transaction is subject to, among other
conditions,  the  approval  by  a  majority  of  the  limited  partners  of  the
Partnership.

The foregoing is a summary only and is qualified in its entirety by reference to
the Master Agreement, which is filed as an exhibit hereto.

On June 25, 1999,  the General  Partner  issued a press release  announcing  the
signing  of the  Master  Agreement.  A copy of the press  release is filed as an
exhibit hereto.

contributions in Section 2.2 hereof have been  consummated)(the  matters in this
clause

                                        7

(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  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

                                        8
<PAGE>
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

                                        9
<PAGE>
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 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)

                                       10
<PAGE>
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 premiums  charged by the lender of a  Non-Terminated  Loan as a
result of the change of control of the GP Interests of any Participating  McNeil
Partnership,  the change in the  ownership  of a majority of the LP Interests in
any Participating  McNeil Partnership,  the change (or change in control) of the
management company for the properties of any Participating  McNeil  Partnership,
the Merger in  respect of such  Participating  McNeil  Partnership  or the other
transactions  expressly  contemplated  by this  Agreement  with  respect to such
Participating McNeil Partnership.

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.

Sections 2.3(a)(i), 2.3(a)(ii) and 2.3(a)(iii) hereof shall be effected pursuant

         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

         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  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

                                       18
<PAGE>
         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' 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

                                       19
<PAGE>
(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 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 to cause to be reprepared  and  redelivered,  in  accordance  with Section
2.4(a) 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

                                       20
<PAGE>
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 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

                                       21
<PAGE>
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  into by  representatives  of the
Company prior to the date hereof.

                                   THE MERGERS

                  Section  3.1 The  Mergers.  Upon the terms and  subject to the
conditions set forth in this  Agreement,  and in accordance  with the applicable
Governing Laws, the Transitory  Partnership  corresponding to each Participating
Merging  Partnership  shall  merge  with and into its  respective  Participating
Merging  Partnership at the Effective  Time.  Following the Effective  Time, (i)
each such Participating  Merging Partnership shall be the surviving  partnership
(the "Surviving  Partnership") in such merger and (ii) the applicable New GP LLC
that  was  the  general  partner  of  such  Participating   Merging  Partnership
immediately  following  the  MPLP  Contributions  and  immediately  prior to the
Effective Time shall be the sole general partner of its corresponding  Surviving
Partnership  and the Company or the Sub LLC shall be the sole limited partner of
each  Surviving  Partnership.  The  mergers  described  in this  Section 3.1 are
collectively referred to in this Agreement as the "Mergers."

                  Section 3.2       Effective Time.

                  (a)  Subject  to the  terms and  conditions  set forth in this
Agreement,  for  each  Participating  Merging  Partnership  and  its  respective
Transitory Partnership, a certificate of merger, articles of merger, certificate
of cancellation,  statement of merger or such other documents as may be required
by the Governing Law applicable to such  Participating  Merging  Partnership and
its corresponding  Transitory Partnership (each, a "Merger Certificate"),  shall
be  duly  executed  and  acknowledged  by the  applicable  New GP  LLC  (or  its
designee),  as the general partner of such Participating Merging Partnership and
its  corresponding  Transitory  Partnership,  and  thereafter  delivered  to the
Secretary of State of the state of formation of such

                                       22
<PAGE>
Participating Merging Partnership, as set forth on Schedule 4.1(c) of the Seller
Disclosure Letter.

                  (b) The Mergers  shall  become  effective  at such time on the
Closing  Date (or such later time as the parties may agree upon and set forth in
each of the Merger  Certificates)  (the "Effective Time" in respect of each such
Merger) as specified in properly  executed  and  certified  copies of the Merger
Certificate for each  Participating  Merging  Partnership and its  corresponding
Transitory  Partnership  are duly filed with the Secretary of State of the state
of formation of such Participating Merging Partnership, as set forth on Schedule
4.1(c) of the Seller  Disclosure  Letter,  in accordance  with the Governing Law
applicable  to each such  Merger.  To the  extent  permitted  by the  applicable
Governing  Law,  each  Merger  Certificate  shall be so  filed at least  one (1)
business day prior to the Closing Date.

                   Section 3.3 Effects of the Mergers; LLC Agreement.

                  (a) Each of the Mergers shall have the effects set forth under
the Governing Law applicable to such Merger.

                  (b) At the Effective Time, the Original LLC Agreement shall be
amended and restated in its entirety in the form of the LLC  Agreement.  The LLC
Agreement shall be the organizational document of the Company from and after the
Effective  Time,  until  thereafter  amended as provided  therein or pursuant to
applicable law.

                  Section 3.4  Conversion of  Partnership  Interests.  As of the
Effective  Time,  by virtue of the Mergers and without any action on the part of
any party  hereto,  any of the  Transitory  Partnerships,  any Company  LLC, any
holder of any LP Interest or any holder of any GP Interest:

                  (a) Each LP Interest of each class of LP  Interests in each of
the  Participating  Merging  Partnerships  outstanding  immediately prior to the
Effective  Time shall be  converted  into and shall  become the right to receive
cash (without interest thereon) in an amount equal to the Per Unit Consideration
Amount to which such LP Interest is

                                       23
<PAGE>
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  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  Merging  Partnerships  shall no longer be
outstanding and shall  automatically be 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 to receive the Per Unit Consideration  Amount
and the Positive  Excess Cash Balance (if any) in respect of such  Participating
Merging  Partnership,  in each case, without interest thereon,  to which such LP
Interest is entitled.

                  (b) As of  the  Effective  Time,  each  LP  Interest  in  each
Transitory  Partnership issued and outstanding as of the Effective Time shall be
converted 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

                                       24
<PAGE>
Merger  Consideration  deposited  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 LP Interests (or, in the case of any Participating
Merging Partnership which is a Merging

                                       25
<PAGE>
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  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

                                       26
<PAGE>
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 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

                                       27
<PAGE>
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").

Roll, there are no verbal  agreements with any tenant,  and, to the Knowledge of
Sellers,  there are no parties in adverse  possession  of any part of any McNeil

                  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    products   or   by-products,    asbestos,    presumed
asbestos-containing  material or asbestos- containing material,  lead-containing
paint  or  plumbing,  radioactive  material  or  radon,  urea  formaldehyde  and
polychlorinated  biphenyls.  Except as  disclosed  on Schedule 4.9 of the Seller
Disclosure  Letter or in the reports  referenced in such Schedule 4.9 and except
for Known Defects and except for matters which would not have,  individually  or
in the aggregate, a Seller Material Adverse Effect:

                  (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

<PAGE>
                  (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 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

                                       52
<PAGE>
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 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.
Except for the contracts listed on Schedule 4.11 of the Seller Disclosure Letter
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

                                       53

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 4.12 Related Party Transactions. Set forth on Schedule

                  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

                                       54
<PAGE>
any of them, or the single-employer  plan of a McREMI ERISA Affiliate,  that has
not been  satisfied  in 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 4975 of the Code or

                                       55
<PAGE>
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

                  (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 extent that such

                                       56
<PAGE>
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 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
them  to  maintain  any  amount  of  Indebtedness  with  respect  to any  McNeil
Partnership Property.

                  (e)  Except as set forth on  Schedule  4.15(e)  of the  Seller
Disclosure  Letter,  none of Sellers nor any Seller Subsidiary is a party to any
agreement  relating  to the  management  or leasing  of any  McNeil  Partnership
Property  by any  person  other  than  McREMI,  except  the  commercial  listing
agreements listed on Schedule 4.15(e) of the Seller Disclosure Letter and except
for any service  agreement which either (i) is cancellable  upon no greater than
sixty (60) days' notice or (ii) which requires  Sellers to make annual  payments
pursuant  thereto not in excess of fifty  thousand  dollars  ($50,000) per year.
Complete  and correct  copies of such  commercial  listing  agreements  and such
service agreements have been made available to the Company.

                  (f) None of Sellers  nor any Seller  Subsidiary  is a party to
any agreement  pursuant to which any Seller or any Seller Subsidiary manages any
real properties  other than the McNeil  Partnership  Properties,  except for the
agreements listed on Schedule 4.15(f) of the Seller Disclosure Letter.

                  (g) Except for  budgeted  construction  disclosed  in the most

                  (h) Schedule 4.15(h) of the Seller Disclosure Letter lists all

                  (i)  Except as set forth on  Schedule  4.15(i)  of the  Seller

licensing  necessary,  other than in  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 by the Company of the transactions
contemplated by this Agreement and the

<PAGE>

<PAGE>
prevent the consummation of the transactions  contemplated by this Agreement and

which would not,  individually or in the aggregate,  prevent the consummation of
the  transactions  contemplated  by this  Agreement  and the  other  Transaction
Documents to which the Company, any Company LLC or any Transitory Partnership is
a party. To the Knowledge of the Company,  no material change is required in the

names, copyrights, service marks, franchises,  variances, exemptions, orders and
other   authorizations,   consents  and  approvals  from  Governmental  Entities
necessary  to conduct  its  business as  presently  conducted  except  those the
absence of which  would  not,  individually  or in the  aggregate,  prevent  the
consummation  of the  transactions  contemplated by this Agreement and the other
Transaction  Documents to which the Company,  any Company LLC or any  Transitory
Partnership is a party.

                  Section  5.5  Litigation.  (i)  There  is no suit,  action  or
proceeding  pending in which  service of process has been received by or, to the
Knowledge of the Company,  threatened against or affecting, the Managing Member,

aggregate,  would prevent the consummation of the  transactions  contemplated by
this  Agreement and the other  Transaction  Documents to which the Company,  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
outstanding  against the Managing  Member,  the Company or any subsidiary of the
Company as of the date of this Agreement which would prevent the consummation of

                                       68

contemplated by this Agreement and the other Transaction  Documents to which the

                  Section 5.6 Brokers.  Neither the Managing Member, the Company
nor any  affiliate or  subsidiary  of the Company has entered into any agreement
with any broker,  investment  banker,  financial  advisor or other  person which

any broker's, finder's,  financial advisor's,  valuation or other similar fee or
commission in connection with the transactions contemplated by this Agreement or
the other Transaction Documents.

                  Section  5.7  Investment  Company  Act of  1940.  Neither  the
Managing  Member,  the Company nor any  subsidiary  of the Company is, or at the
Effective Time will be, required to be registered under the 1940 Act.

                  Section 5.8 Financing.  The Company has entered into a written
commitment  letter for financing from Whitehall (the "Commitment  Letter"),  and
Sellers have  received a written  guarantee of the Company's  obligations  under
this Agreement from  Whitehall (the  "Guarantee").  Regardless of whether or not
the  transactions  contemplated by the Commitment  Letter are consummated or the
obligations  under  the  Guarantee  are  performed,  immediately  prior  to  the
Effective  Time,  the  Company  will have  sufficient  funds to  consummate  the
transactions  contemplated  to  occur  at or after  the  Effective  Time by this
Agreement and the other Transaction Documents. A true, correct and complete copy
of the Commitment  Letter and the Guarantee have been delivered to Sellers prior
to the date hereof.  The Commitment  Letter and the Guarantee are, and have been
at all times  since  entered  into,  in full  force and effect and have not been
withdrawn or amended or breached by any party thereto.  Notwithstanding anything
to the  contrary in this  Agreement  or the other  Transaction  Documents or the
Commitment  Letter or the Guarantee (in each case,  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  Managing  Member,  the
Company or any of their respective affiliates or

<PAGE>
subsidiaries  (including affiliates and subsidiaries both prior to and following
the  Effective  Time) of any debt or equity  or other  financing  in any  amount
whatsoever.  The  parties  hereto  acknowledge  and agree  that  nothing in this
Section 5.8 shall affect the condition to Closing set forth in Section 8.2(d)(i)
hereof.

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

                           (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 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

                                       80
<PAGE>
         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.

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  extended  by Sellers

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

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

                                       81
<PAGE>
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
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

                                       82
<PAGE>
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

such Merging  Partnership,  the MPLP  Contributions with respect to such Merging
Partnership, the appointment of the applicable New GP LLC as the general partner

Merger in respect  of such  Merging  Partnership,  the MPLP  Contributions  with
respect to such Merging  Partnership,  the  appointment of the applicable New GP

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.

                  Section 7.2       Acquisition   Proposals.    Prior  to    the
Effective Time, each Seller agrees that:

                  (a) it shall not,  directly or indirectly,  through any of its
officers,  directors,  employees  or agents or  representatives  (including  any
investment  banker,  attorney  or  accountant)  retained by it, and it shall not
authorize   or  permit  its   officers,   directors,   employees  or  agents  or
representatives  (including  any  investment  banker,  attorney  or  accountant)
retained by it to, initiate, solicit or encourage any inquiries or the making or
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;

                                       84
<PAGE>
                  (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 to
furnishing  such  information  to, or entering into  discussions or negotiations
with, such person,  such general partner  provides written notice to the Company
to the effect that it is furnishing information to, or entering into discussions
with, such person and (C) (1) subject to clause (2) below,  such general partner
keeps the Company informed of the status (not the terms) of any such discussions
or negotiations  and (2) such general partner complies with the last sentence of
Section  9.3(b)  hereof;  or (ii) to the extent  applicable,  shall prohibit the
general  partner of any McNeil  Partnership  from taking and  disclosing  to the
limited  partners of such McNeil  Partnership  a position,  with respect to such
McNeil Partnership, contemplated by Rules 14d-9 and 14e-2 under the Exchange Act
with regard to an  Acquisition  Proposal for such McNeil  Partnership;  provided
further, however, that the general partner of any McNeil Partnership may approve
and recommend a Superior Acquisition Proposal and,

                                       85
<PAGE>
in connection  therewith,  withdraw or modify its approval or  recommendation of
this  Agreement,  the  Merger in respect of such  McNeil  Partnership,  the MPLP
Contributions  with respect to such McNeil  Partnership,  the appointment of the
applicable  New  GP  LLC  as  the  successor  general  partner  of  such  McNeil
Partnership and the other transactions contemplated by this Agreement,  prior to
the approval by the holders of LP Interests of such McNeil  Partnership  of this
Agreement,  the  Merger  in  respect  of  such  McNeil  Partnership,   the  MPLP
Contributions  with respect to such McNeil  Partnership,  the appointment of the
applicable  New  GP  LLC  as  the  successor  general  partner  of  such  McNeil
Partnerships  and the other  transactions  contemplated by this Agreement at the
McNeil  Limited  Partner  Meeting  (or any  adjournment  thereof) of such McNeil
Partnership.  Any disclosure that the general partner of any McNeil  Partnership
may be compelled to make with respect to the receipt of an Acquisition  Proposal
for such  McNeil  Partnership  in order to comply with its duties to its limited
partners or that the general partner of any McNeil  Partnership may be compelled
to make in order to comply  with Rule  14d-9 or 14e-2,  shall not  constitute  a
violation of this  Section 7.2,  provided  that such  disclosure  states that no
action shall be taken by such general  partner with respect to the withdrawal of
its  recommendation of the transactions  contemplated  hereby or the approval or
recommendation  of any  Acquisition  Proposal  except  in  accordance  with this
Section 7.2.

                  Section 7.3       Access to Information; Confidentiality.

                  (a) Subject to the requirements of confidentiality  agreements
entered  into with third  parties  and  subject to all other  legal  limitations
(including   attorney-client  and  work  product  privileges,   confidentiality,
antitrust  and fair trade  limitations),  Sellers  shall (and shall  cause their
respective  Seller  Subsidiaries  to) afford to the Company and to the officers,
employees, accountants, counsel, financial advisors and other representatives of
the  Company,  reasonable  access  during  normal  business  hours  prior to the
Effective  Time  to such  Sellers'  and  such  Seller  Subsidiaries'  respective
properties,  books, contracts,  commitments,  personnel and records, and Sellers
shall (and

                                       86
<PAGE>
shall cause their respective Seller  Subsidiaries to) promptly make available to
the Company or its representatives all information  concerning such Sellers' and
such Seller Subsidiaries'  respective business,  properties and personnel as the
Company or its representatives may reasonably request;  provided,  however, that
no  investigation  pursuant  to this  Section  7.3 shall  affect or be deemed to
modify any representation or warranty made by Sellers.

                  (b)  Following  the  date  of this  Agreement  and  until  and
including the Closing Date, Sellers will prepare in accordance with GAAP applied
consistently  with past  practice  and make  available to the Company (i) within
forty-five  (45) days  following  the end of any fiscal  quarter,  a copy of the
unaudited quarterly balance sheet and related unaudited statements of operations
and cash flows for such quarter for each Private  McNeil  Partnership  that is a
Participating  McNeil Partnership at such time and (ii) within fifteen (15) days
following the end of each fiscal month, a copy of the unaudited  monthly balance
sheet and related  unaudited  statements of  operations  and cash flows for such
month for each  Participating  McNeil  Partnership and a Preliminary Excess Cash
Balance Schedule for each such Participating McNeil Partnership. Sellers and the
Company will use their best efforts to respond to any  inquiries  any such party
may have concerning such quarterly and monthly financial  statements and monthly
Preliminary  Excess Cash Balance  Schedules.  No such  discussion  or failure to
raise  issues  shall  become  final and  binding  upon any party  hereto  except
pursuant to Section 2.4(b) hereof.

                  (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
information  relating  to  Sellers or the  Seller  Subsidiaries  or any of their
respective businesses or properties in confidence to the extent required by, and
in accordance with, the provisions of the letter agreement dated as of March 25,
1999  among  Whitehall,  MPLP  and  McREMI  (the  "Confidentiality  Agreement"),
regardless of whether such  information  was disclosed  pursuant to this Section
7.3 or any other provision of this Agreement.

                  Section 7.4       Reasonable Best Efforts; Notification.

                  (a)  Subject  to the terms  and  conditions  provided  in this
Agreement,  Sellers,  on the one hand, and the Company, on the other hand, shall
use their respective  reasonable best efforts: (i) to cooperate with one another
in (A) determining which consents,  approvals,  orders or authorizations  of, or
filings  with,  any  Governmental  Entities  are required to be obtained or made
prior to the  Effective  Time in  connection  with the execution and delivery of
this Agreement and the other Transaction Documents,  and the consummation of the

authorizations;  (ii) subject to Section 7.8 hereof,  without the payment of any
consideration  therefor (except as expressly contemplated by this Agreement) and
without  compromising  their respective rights and without incurring  additional
liabilities or obligations, to obtain in writing any consents, approvals, orders
or authorizations required from non-governmental third parties to effectuate 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 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

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 in connection with such cooperative efforts.

                  (c) Promptly  following  the  Effective  Time,  McREMI or MPLP
shall file Schedule K-1s with supporting documents (not including Form 15s) with
respect to the Participating McNeil Partnerships to reflect the change of 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

                                       89
<PAGE>
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

                                       90
<PAGE>
         "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 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

                                       91
<PAGE>
         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 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

                                       92
<PAGE>
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
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

                                       93
<PAGE>
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 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.

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

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

                  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

                                       95
<PAGE>
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  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

                                       96
<PAGE>
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  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

                                       97
<PAGE>
"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

                                       98
<PAGE>
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 no
adjustment  shall be made to the cash line item to  reflect  any  payment of the
Summerhill Note or any contribution of cash to effect such payment.

                  Section  7.12  Stanger   Reports.   Sellers  shall  use  their
reasonable  best  efforts to obtain  from  Stanger  the  Stanger  Opinions,  the
Allocation  Analysis  and,  if  requested,  the  Appraisals,  and to obtain from
Eastdil the Eastdil Opinions,  in each case on or prior to the date on which the
Proxy Statements are mailed to the limited  partners of the McNeil  Partnerships
in accordance with Section 7.1 hereof.

                  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

                                       99
<PAGE>
Agreements,  the parties hereto acknowledge and agree that Sellers shall have no
obligation  to comply with such  requests of the Company  until  Sellers and the
Company  reach  a  mutually  acceptable  agreement  as  to  the  timing  of  the
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
Section  7.13(b)  shall  limit,  amend or  modify  any other  provision  of this
Agreement  (including  Sections 5.8, 8.1, 8.2 and 8.3 hereof),  or shall require
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
additional liabilities or obligations.

                  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.

                                       100
<PAGE>
                  (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 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

                                       101
<PAGE>
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 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

                                       102
<PAGE>
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 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

                                       103
<PAGE>
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).

Governmental  Entity of  competent  jurisdiction  shall  have  enacted,  issued,
promulgated,  enforced  or entered  any  statute,  rule,  regulation,  judgment,
decree, injunction or

                                       104

Participating  McNeil  Partnerships  which  would  result  in a Seller  Material
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
instituted any proceeding  seeking any such Order which is reasonably  likely to
succeed.

all  consents,  approvals,  orders or  authorizations  from,  or  filings  with,

the  applicable  New  GP  LLCs  as the  general  partner  of  its  corresponding
Participating  McNeil  Partnership or any other transactions with respect to the

         not to give effect to any materiality or Seller Material Adverse Effect
         qualifiers contained therein),  as though made on and as of the Closing

         expressly  limited by its terms to a specific  date, in which case 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

         of the Closing Date in  accordance  with  Section 8.4 hereof)  shall be
         true  and   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 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.

                  (b) Performance of Obligations of Sellers.  Sellers shall have

         attached as 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) provided such form of consent is substantially comparable to

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 in
this  Agreement  or in the Title  Commitments,  the title  exceptions  listed on

satisfied in determining whether or not this Section 8.2(e) has been satisfied.

                  (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  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,  or at and as of such other date, would not prevent the Company,  any

         Allocations  is fair from a  financial  point of view to the holders of

                           (ii)  Eastdil  shall have  delivered  to the  Special

                  (a) Notwithstanding anything to the contrary in this Agreement
(including Sections 8.1, 8.2 and 8.3 hereof), the parties hereto acknowledge and
agree that, in  accordance  with Section 9.4 hereof,  none of the  conditions to
Closing  set forth in  Sections  8.1,  8.2 and 8.3 hereof  shall be deemed to be
unsatisfied because such condition was not satisfied with respect to an Excluded
McNeil Partnership (or such Excluded McNeil Partnerships'

                                       112
<PAGE>
subsidiaries,  properties,  etc.) (i.e., since no Excluded McNeil Partnership is
subject to the Closing, the conditions to the Closing need not be satisfied with
respect to any Excluded McNeil Partnership,  such Excluded McNeil  Partnerships'
subsidiaries, properties, etc.).

                  (b) Notwithstanding anything to the contrary in this Agreement
(including  Sections 8.1 and 8.2 hereof),  the following shall not be considered
in determining whether or not any or all of the conditions set forth in Sections

Participating McNeil Partnerships' business, properties,  financial condition or
results of  operations  resulting,  directly or  indirectly,  from the Company's
failure to consent to a  Commercial  Lease or any  amendment  to any  Commercial
Lease as requested by Sellers in good faith  pursuant to Section  6.1(l) hereof;
and (ii) any effect on any of the Participating McNeil  Partnerships'  business,
properties,  financial condition or results of operations resulting, directly or
indirectly,  from the Company's  failure to consent to a  Reimbursable  Proposal
proposed by Sellers in good faith.

                  (c) Notwithstanding anything to the contrary in this Agreement
(including Sections 8.1, 8.2 and 8.3 hereof), the parties hereto acknowledge and
agree that none of the  Discretionary  Closing  Conditions shall be deemed to be
unsatisfied  because such condition was not satisfied with respect to any one or
more  Included  McNeil  Partnerships  (or  such  Included  McNeil  Partnerships'
subsidiaries, properties, etc.).

                  (d) Notwithstanding anything to the contrary in this Agreement
(including Sections 8.1, 8.2 and 8.3 hereof), the parties hereto acknowledge and
agree that none of the  Discretionary  Closing  Conditions shall be deemed to be
unsatisfied  because such condition was not satisfied with respect to any one or
more Included Partnership Matters.

                  (e) Notwithstanding anything to the contrary in this Agreement
(including Sections 8.1, 8.2 and 8.3 hereof), the parties hereto acknowledge and
agree that Section  7.15(b)  hereof  shall be given effect prior to  determining
whether or not any or all of the conditions

                                       113
<PAGE>
set forth in Sections 8.1 and 8.2 hereof have been fulfilled.

                  Section 8.5       Removal Notices.

                  (a) In the case of any Participating  McNeil  Partnership,  at
any time  after the date of this  Agreement  through  to the date of the  McNeil
Limited Partner Meeting for such Participating  McNeil Partnership,  the Sellers
may  provide a written  notice  (the  "Matter  Removal  Notice")  to the Company
identifying such Participating  McNeil Partnership as a "Removable  Partnership"
and which shall describe in reasonable  detail certain matters  relating to such
Participating  McNeil  Partnership  as  "Designated  Partnership  Matters"  that
Sellers believe in good faith may cause the Participating  McNeil Partnership to
become an Excluded McNeil Partnership.

                  (b) Upon the Company's  receipt of the Matter  Removal  Notice
(the  earlier  of (1) the tenth  full  business  day  following  the date of the
Company's  receipt of the Matter  Removal Notice and (2) the third full business
day  following  the date of the  Company's  receipt of the Pre- Closing  Removal
Notice,  the "Matter  Removal Notice  Date"),  the Company shall have until 5:00
p.m., New York City time, on the Matter  Removal Notice Date to provide  written
notice to Sellers,  which notice shall identify which (if any) of the Designated
Partnership Matters the Company designates as an "Included Partnership Matter."

                  (c) In the case of any Participating  McNeil  Partnership,  at
any  time  following  the  date of the  McNeil  Limited  Partner  Meeting  for a
Participating McNeil Partnership,  the Sellers may provide a written notice (the
"Pre-Closing  Removal  Notice") to the Company  identifying  such  Participating
McNeil Partnership as a "Pre-Closing Removable Partnership" which may or may not
(in the sole and absolute  discretion of the Sellers)  designate  certain of the
McNeil  Partnership  Properties of such  Pre-Closing  Removable  Partnership  as
"Designated Partnership Properties."

                  (d) Upon the  Company's  receipt of the Pre-  Closing  Removal
Notice (the third full business day following the date of the Company's  receipt
of the Pre- Closing Removal Notice, the "Pre-Closing  Removal Notice Date"), the
Company  shall  have until 5:00  p.m.,  New York City time,  on the  Pre-Closing
Removal  Notice Date to provide  written  notice to Sellers,  which notice shall
identify which (if any) of the Pre-Closing  Removable  Partnerships  the Company
designates as an "Included McNeil Partnership."

                  (e) The parties hereto acknowledge and agree that the exercise
(or lack of  exercise)  by any Seller of its rights  under  Sections  8.5(a) and
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 agreement in this Agreement or that the conditions to Closing with respect to
any McNeil Partnership were not, in fact, satisfied.

                  (f)  If  the  Closing   occurs  and  if  one  or  more  McNeil
Partnerships  became an Excluded  McNeil  Partnership  by  operation  of Section
9.3(f),  9.3(g) or 9.3(h) hereof, each party to this Agreement hereby waives any
rights it may have to file or commence any suit,  action or  proceeding  against
each other party to this Agreement or their  respective  affiliates with respect
to  any  such  Excluded   McNeil   Partnership   and  hereby   irrevocably   and
unconditionally  releases each such other party and its affiliates  from any and
all  claims,  known  or  unknown,  it may  have  relating  to  the  transactions
contemplated by this Agreement and the other Transaction  Documents with respect
to any such Excluded McNeil Partnership.

is not  curable  or, if  curable,  is not cured  within  thirty  (30) days after

Prior to the Effective Time. Certain rights and obligations under this Agreement
of one or more McNeil Partnerships (each, an "Excluded McNeil  Partnership") and

or not the requisite  approvals of the respective limited partners of the McNeil
Partnerships  have been obtained (except as indicated to the contrary below)) as
follows:

                  (a) by the  Company,  on the one hand,  or any Seller,  on the
other hand,  upon  written  notice  given to the other if, upon a vote at a duly
held McNeil Limited Partner Meeting (or any adjournment thereof) for such McNeil
Partnership,  the  requisite  approval  of the  limited  partners of such McNeil
Partnership  of the  Merger in  respect  of such  McNeil  Partnership,  the MPLP

such McNeil  Partnership as to its fiduciary  duties to the limited  partners of
such McNeil  Partnership as imposed by law, such general partner,  as advised by
counsel,  determines  that such  termination is required by reason of a Superior
Acquisition  Proposal being made with respect to such McNeil  Partnership.  Each
McNeil  Partnership  agrees  that it shall  not  enter  into a  binding  written
agreement with respect to an Acquisition  Proposal without providing the Company
with at least four business days prior notice of

modified in a manner adverse to the Company its approval or recommendation  that
the limited partners of such McNeil Partnership approve the Merger in respect of
such McNeil  Partnership,  the MPLP  Contributions  with  respect to such McNeil
Partnership,  the  appointment  of the  applicable  New GP LLC as the  successor
general  partner  of  such  McNeil   Partnership  and  the  other   transactions
contemplated  by this  Agreement  with  respect to such McNeil  Partnership,  in
connection with an Acquisition Proposal for such McNeil Partnership,  or (C) has
approved or recommended an Acquisition Proposal for such McNeil Partnership;

                  (d) by the  Company,  on the one hand,  or any Seller,  on the
other hand, with respect to a McNeil  Partnership,  upon written notice given to
the  other  if  any  judgment,  injunction,  order,  decree  or  action  by  any
Governmental  Entity of competent  authority  preventing the consummation of the
transactions  contemplated  by  this  Agreement  with  respect  to  such  McNeil
Partnership shall have become final and nonappealable;

subsidiaries  as a result of the failure of the Merger of such  Excluded  McNeil
Partnership  and the other  transactions  contemplated  by this  Agreement  with
respect to such Excluded  McNeil  Partnership to be consummated and to avoid the
difficulty of determining damages under the

                                       122

                               GENERAL PROVISIONS

                  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
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

                                       139
<PAGE>
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 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

                                       140
<PAGE>
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,  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 11.9 Assignment. Neither this Agreement nor any of the
rights,  interests  or  obligations  under this  Agreement  shall be assigned or

                  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  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

                                       144
<PAGE>
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.

McNeil Partnerships to Merge With an Affiliate of Whitehall

DALLAS, Texas, June 25, 1999 -- McNeil Partners,  L.P., a privately held sponsor
of real  estate  partnerships,  and  WXI/McN  Realty  L.L.C.,  an  affiliate  of
Whitehall  Street Real Estate Limited  Partnership XI, a real estate  investment
fund managed by Goldman,  Sachs & Co.,  today  announced  that they have entered
into a definitive  acquisition  agreement  whereby the Whitehall  affiliate will
acquire by merger nineteen real estate limited  partnerships  operated by McNeil
Partners,  L.P.  and Robert A.  McNeil.  The limited  partnerships  involved are
McNeil Real Estate Funds IX, X, XI, XII, XIV, XV, XX, XXI,  XXII,  XXIII,  XXIV,
XXV,  XXVI and XXVII,  Hearth  Hollow  Associates,  McNeil  Midwest  Properties,
Regency   North   Associates,   Fairfax   Associates   and   McNeil   Summerhill
(collectively,  the  "Partnerships").   The  Partnerships  (other  than  Fairfax
Associates and McNeil  Summerhill which are wholly-owned by Robert A. McNeil and
related  parties) will be merged with  subsidiaries of WXI/McN Realty L.L.C. The
acquisition agreement also provides for the acquisition by WXI/McN Realty of the
assets of McNeil  Real  Estate  Management,  Inc.  ("McREMI"),  the real  estate
investment and management  company controlled by Robert A. McNeil. The aggregate
consideration in the transaction, including all outstanding mortgage debt of the
Partnerships, is approximately $644,440,000.

Pursuant to the terms of the acquisition agreement, the limited partners in each
of the  Partnerships  (other than those  wholly-owned  by Robert A. McNeil) will
receive  cash on the  closing  date of the  transaction  in  exchange  for their
limited partnership interests. In addition, each Partnership will make a special
distribution  to its limited  partners on the  closing  date of the  transaction
equal to its then net positive  working capital balance.  McNeil Partners,  L.P.
will  receive  an  equity  interest  in  WXI/McN  Realty  in  exchange  for  its
contribution  of its general  partnership  interests  in the  Partnerships,  the
limited partnership interests in its wholly owned Partnerships and the assets of
McREMI.

The proposed  transaction  follows an extensive  marketing effort by PaineWebber
Incorporated, exclusive financial advisor to the Partnerships.

The  transaction  has been  unanimously  approved by the Board of  Directors  of
McNeil  Investors,  Inc.,  the general  partner of McNeil  Partners,  L.P.,  the
general partner of each of the  Partnerships  other than Regency North,  Fairfax
Associates and McNeil  Summerhill.  The respective  general  partners of Regency
North,   Fairfax  Associates  and  McNeil  Summerhill  also  have  approved  the
transaction. The Board of Directors of McNeil Investors based its approval upon,
among other  things,  the  recommendation  of a Special  Committee of the Board,
appointed at the beginning of the  discussions  with  Whitehall to represent the
interests  of  holders  of  limited   partnership   interests  in  each  of  the
Partnerships.  In  addition,  the Special  Committee  and the Board  relied upon
fairness  opinions given by Robert A. Stanger & Co., Inc.  ("Stanger & Co."), an
independent  financial  advisor  to the  Partnerships,  to the  effect  that the
aggregate  consideration  is  fair  to the  holders  of each  class  of  limited
partnership   interests   in   each   Partnership.   The   Special   Committee's
recommendation  was also  based upon the  separate  opinions  of Eastdil  Realty
Company, the independent  financial advisor to the Special Committee.  Stanger &
Co.  and  Eastdil  have  each  also  rendered  an  opinion  that  the  aggregate
consideration  to be paid for the  general  partnership  interests  and  limited
partnership  interests  in all of the  Partnerships  and the assets of McREMI is
fair from a  financial  point of view to the  holders  of each  class of limited
partnership interests in each of the Partnerships.



<PAGE>
Each  Partnership's  participation in the transaction is subject to, among other
conditions,  the  approval  by a  majority  of  the  limited  partners  of  that
Partnership.  The approval of the limited partners of the  Partnerships  will be
sought at  meetings  to be held in the coming  months  after the filing of proxy
statements  with the  Securities  and  Exchange  Commission  with respect to the
publicly traded Partnerships,  and the subsequent mailing of proxy statements to
the limited partners.

The aggregate  consideration in the transaction has been allocated preliminarily
among the general partnership interests and the limited partnership interests in
each of the Partnerships and McREMI,  based upon an allocation analysis prepared
by Stanger & Co. and confirmed by Eastdil.  Based upon this allocation  analysis
and the fairness  opinions  rendered by Stanger & Co. and  Eastdil,  the Special
Committee,  the Board of Directors of McNeil Investors,  the respective  general
partners of Regency North,  Fairfax  Associates and McNeil  Summerhill have each
unanimously  approved  the  allocation  of  the  aggregate  consideration.   The
estimated  aggregate  consideration  and  working  capital  distribution  to  be
received per unit of limited  partnership  interest,  is currently  estimated as
follows:

                                                             Estimated

McNeil Partners,  L.P. will contribute its real estate investment and management
company  business to a  subsidiary  of WXI/McN  Realty,  L.L.C.,  along with its
general  partnership  interests in the Partnerships and its limited  partnership
interests in the wholly-owned Partnerships, having an aggregate allocated value,
as  determined  by  Stanger  &  Co.,  of  approximately  $58,640,000,  of  which
approximately  $29,400,000  reflects  balances due to McNeil and  affiliates  as
reflected on the Partnership financial statements as of March 31, 1999.

The above estimates of the per unit estimated merger  consideration  and working
capital  distribution and the interest of McNeil Partners,  L.P. are based upon,
among other things,  the balance sheet of each Partnership as of March 31, 1999,
adjusted for intangible assets,  non-cash liabilities,  transaction expenses and
the McNeil Partners,  L.P.  interest in each  Partnership.  The McNeil Partners,
L.P.  interest  in each  Partnership  includes  all  amounts  payable  to McNeil
Partners,  L.P. as  reflected  on the balance  sheet as of March 31,  1999,  the
McNeil  Partners,  L.P. general  partnership  interest in respect of its capital
contribution less the deficit  restoration  obligation of McNeil Partners,  L.P.
pursuant to the partnership agreements.  Actual amounts,  including the estimate
allocable  to McNeil  Partners,  L.P.,  will vary  with the  performance  of the
Partnership  and McNeil  Partners,  L.P.  through  the closing  date.  The above
estimated merger  consideration and special working capital distribution will be
adjusted  at  closing to  reflect  the then  working  capital  position  of each
Partnership.

Robert and Carole McNeil stated that:  "We are very pleased to have entered into
this  transaction  that will  result in the  McNeil  Partnerships  being sold to
Whitehall on a basis which we believe is very favorable to our limited partners.
The price reflects the quality and  dedication of our management  team who, over
the past 8 years, have worked to optimize the value of these properties. We also
believe that this transaction will provide shorter term liquidity to our limited
partners than would have been obtainable had the partnerships been liquidated on
an individual basis."

Whitehall  Street Real Estate  Limited  Partnership XI is a $2.26 billion equity
fund and is the  seventh  in a series  of funds  sponsored  and  capitalized  by
Goldman,  Sachs  & Co.  and  its  affiliates,  along  with  public  and  private
investors, to acquire real estate worldwide.

such  Partnership's  financial  results is  included in such  Partnership's  SEC
