                             [NAME OF PARTNERSHIP]

 To the Limited Partners of [Name of Partnership]--YOUR VOTE IS VERY IMPORTANT


   You are cordially invited to attend a meeting of the Partnership's limited
partners. At the meeting, holders of limited partner units in the Partnership
will consider and vote on the proposals described in the accompanying notice
of meeting. These proposals are being proposed by McNeil Partners, L.P., the
Partnership's general partner.

   The date, time and place of the meeting are as follows:

   [Weekday], [Month, Day], 1999
      , local time
   [Location]

   The Partnership has entered into an acquisition agreement whereby WXI/McN
Realty L.L.C., a newly formed company affiliated with Whitehall Street Real
Estate Limited Partnership XI, will acquire the general partner interests and
limited partner interests in the Partnership, the general partner interests
and limited partner interests in eighteen other partnerships controlled by
McNeil Partners and its affiliates, certain assets of McNeil Partners and
certain assets of McNeil Real Estate Management, Inc., the management company
for the Partnership's properties.

   In the proposed transaction, the Partnership will merge with a subsidiary
of WXI/McN Realty, and each limited partner of the Partnership [additional
disclosure for Funds XX-XXVI: (other than limited partners who validly
exercise dissenters' rights in connection with the merger)] will receive an
aggregate of approximately [for all except Funds XXI-XXVIII: $   in cash for
each limited partner unit] [for Funds XXI-XXIII: $   in cash for each current
income unit and $   in cash for each growth/shelter unit] in the Partnership.
Following the merger, you will no longer be a limited partner of the
Partnership. The aggregate amount to be received for each limited partner unit
consists of cash merger consideration of $   per unit and a special
distribution in cash estimated as of       , 1999 to be $   per unit.

   [Additional disclosure for Funds XX-XXVI: In lieu of receiving $   in cash
for each of their limited partner units, limited partners of the Partnership
who do not vote for the merger proposal and who otherwise comply with the
provisions of Article 7.6 of the California Revised Limited Partnership Act
will be entitled to dissenters' rights with respect to their limited partner
units if the Partnership participates in the transaction and the transaction
is completed.]

   The transaction will provide you with the opportunity to liquidate your
investment in the Partnership for cash at a price and on terms that McNeil
Partners believes is fair to and in the best interests of the limited partners
of the Partnership. If the Partnership participates in the transaction, all
SEC reporting obligations of the Partnership will cease. Unlike in a
liquidation, the merger transaction will not require limited partners to
continue to hold interests in the Partnership until all contingent liabilities
have been settled. You should be aware that McNeil Partners will receive an
equity interest in WXI/McN Realty if the transaction is completed.

   The Partnership cannot participate in the transaction unless limited
partners holding greater than [for all except Funds XXI-XXIII: 50% of the
limited partner units] [for Funds XXI-XXIII: 50% of each class of limited
partner units] in the Partnership approve the merger proposal described in the
accompanying notice of meeting. Only limited partners who held their limited
partner units in the Partnership at the close of business on      , 1999 will
be entitled to vote at the meeting.

   The board of directors of McNeil Investors, Inc., the corporate general
partner of McNeil Partners, based upon the recommendation of a special
committee and fairness opinions rendered by Robert A. Stanger & Co., Inc., has
unanimously determined that the transaction is fair to and in the best
interests of the Partnership and its limited partners. The McNeil Investors
board of directors has unanimously approved the merger proposal and
unanimously recommends that you vote to approve the merger proposal.

   This Proxy Statement explains in detail the terms of the proposed
transaction and related

partners of the Partnership on     , 1999.

meeting, please complete, date, sign and promptly return the accompanying

at the meeting, it will have the effect of voting your limited partner units
against the merger proposal.

   On behalf of McNeil Partners, I thank you for your support and appreciate
your consideration of these matters.

                  QUESTIONS AND ANSWERS ABOUT THE TRANSACTION

   The following questions and answers are intended to provide brief answers to
some commonly asked questions. These questions and answers do not, and are not
intended to, address all questions that may be important to you. The following
questions and answers are qualified in their entirety by reference to the more
detailed information contained elsewhere in this Proxy Statement, the
Appendices to this Proxy Statement and the other documents to which we have
referred you. For a summary description of the parties to the transaction
referred to in the questions and answers below, see "Summary--Parties to the
transaction."

Q: What is the transaction?

A: The transaction is the acquisition by a newly formed affiliate of Whitehall
   Street Real Estate Limited Partnership XI of the Partnership, up to eighteen
   other McNeil Partnerships controlled by McNeil Partners and its affiliates,
   assets of McNeil Partners related to the participating McNeil Partnerships
   and certain assets of McNeil Real Estate Management, Inc., the management
   company for the McNeil Partnerships' properties. Whitehall Street Real
   Estate Limited Partnership XI is a real estate investment fund whose
   investment manager is Goldman, Sachs & Co. If the Partnership participates
   in the transaction, you will receive an aggregate of approximately [for all
   except Funds XXI-XXIII: $   in cash for each of your limited partner units]
   [for Funds XXI-XXIII: $   in cash for each of your current income units and
   $   in cash for each of your growth/shelter units] in the Partnership, and
   you will no longer be a limited partner of the Partnership. The aggregate
   amount to be received for each limited partner unit consists of cash merger
   consideration of $     per unit and a special distribution in cash estimated
   as of     , 1999 to be $     per unit.

Q: Why is McNeil Partners proposing the transaction?

A: The transaction represents the culmination of nearly two years of efforts by
   McNeil Partners to achieve a sale of the McNeil Partnerships. The terms of
   the transaction have been approved by the McNeil Investors board of
   directors, based upon the recommendation of an independent special committee
   of the McNeil Investors board of directors, and is the subject of fairness
   opinions from two real estate investment banks. Consummation of the
   transaction will satisfy the obligations of McNeil Partners to liquidate the
   public McNeil Partnerships prior to the end of 1999. Moreover, counsel to
   the plaintiffs in the Schofield litigation against McNeil Partners and its
   affiliates described below has reviewed the terms of the transaction and
   oversaw the auction process.

Q: Why should I vote for the merger proposal?

A: The transaction will allow you to liquidate your investment in the
   Partnership for cash. Moreover, the McNeil Investors board of directors has
   unanimously determined that the transaction is fair to and in the best
   interests of the Partnership and its limited partners. In making its
   determination, the board of directors relied on the recommendation of a
   special committee of the McNeil Investors board of directors and on fairness
   opinions delivered by Robert A. Stanger & Co., Inc. ("Stanger & Co.") on
   behalf of the McNeil Partnerships to the effect that the aggregate
   consideration, the allocations of the aggregate consideration and the per
   unit estimated aggregate amount to be received by each class of limited
   partners of the McNeil Partnerships are each fair from a financial point of
   view to the holders of [for all except Funds XXI-XXIII: limited partner
   units] [for Funds XXI-XXIII: each class of limited partner units] in the
   Partnership. Additionally, SEC reporting obligations of the Partnership will
   cease as a result of the transaction, and the limited partners will not be
   required to continue holding interests in the Partnership until all
   contingent liabilities have been settled.

Q: What is the structure of the transaction?

A: WXI/McN Realty, a newly formed company affiliated with Whitehall Street Real
   Estate Limited Partnership XI, will acquire the general partner interests
   and limited partner interests in the Partnership, the general partner
   interests and limited partner interests in the other McNeil Partnerships
   included in the transaction, assets of McNeil Partners related to the
   participating McNeil Partnerships and certain

                                       1
<PAGE>

   assets of McREMI, the management company for the McNeil Partnerships'
   properties. Following the closing of the transaction, McNeil Partners will
   receive an equity interest in WXI/McN Realty.

Q: Why doesn't the Partnership just sell all of its properties?

A: McNeil Partners believes that the transaction will provide more immediate
   liquidity to the limited partners of the Partnership than would have been
   obtainable had the Partnership been liquidated on a property by property
   basis. Additionally, all SEC reporting obligations of the Partnership will
   cease as a result of the transaction, and the limited partners will not be
   required to continue holding interests in the Partnership until all
   contingent liabilities have been settled.

Q: Why are the McNeil Partnerships being acquired by merger?

A: In addition to the benefits described in the preceding answer, McNeil
   Partners believes that a merger achieves several additional benefits to the
   limited partners of the McNeil Partnerships that would not be achieved in a
   property by property liquidation of the McNeil Partnerships. Among other
   things, structuring the transaction as a merger eliminated the difficulties
   that would have been encountered if prospective purchasers were allowed to
   purchase the more attractive properties, leaving behind the less attractive
   properties that could prove time consuming and expensive for an individual
   McNeil Partnership to liquidate. Moreover, a merger may permit the McNeil
   Partnerships to avoid the payment of certain transfer taxes associated with
   a sale of the properties. In addition, a merger of the McNeil Partnerships
   would not trigger certain due-on-sale covenants in the mortgage debt of some
   of the McNeil Partnerships that otherwise might be triggered by a sale of
   the individual properties of those McNeil Partnerships. The transaction, as
   structured, also will allow McNeil Partners to make the contributions of its
   interests in the McNeil Partnerships and the assets of McNeil Partners and
   McREMI to WXI/McN Realty on a tax-free basis and to defer substantial income
   tax liability that would be incurred if there had been a taxable sale of the
   properties.

Q: Why are the McNeil Partnerships and the assets of McREMI being sold as a
   single portfolio instead of in separate transactions?

A: At the commencement of its engagement, PaineWebber Incorporated, the McNeil
   Partnerships' exclusive financial advisor, advised McNeil Partners that the
   highest price for the McNeil Partnerships and, therefore, the greatest
   distribution to the limited partners of each of the McNeil Partnerships,
   would likely be achieved by offering the McNeil Partnerships and McREMI
   together on an all-or-none basis. PaineWebber perceived the advantages of an
   all-or-none transaction as compared to separate asset sales of individual
   McNeil Partnerships to include, among others, relatively quick liquidity, a
   less time-consuming marketing period and the likelihood of a higher
   aggregate purchase price. Among other factors, McNeil Partners itself
   preferred an all-or-none transaction because it believed that the uneven
   performance of the various properties owned by the McNeil Partnerships might
   allow prospective purchasers to "cherry-pick" the most desirable assets to
   the detriment of the others.

Q: What will I receive in the transaction?

A: If the Partnership participates in the transaction, limited partners of the
   Partnership will receive an aggregate of approximately [for all except Funds
   XXI-XXIII: $   in cash for each limited partner unit] [for Funds XXI-XXIII:
   $   in cash for each current income unit and $   in cash for each
   growth/shelter unit] held by them. [for all except Funds XXI-XXIII: The
   aggregate amount to be received for each limited partner unit consists of
   cash merger consideration of $    per unit and a special distribution in
   cash estimated as of     , 1999 to be $    per unit.] [for Funds XXI-XXIII:
   The aggregate amount to be received for each current income unit consists of
   cash merger consideration of $    per unit and a special distribution in
   cash estimated as of      , 1999 to be $    per unit. The aggregate amount
   to be received for each growth/shelter unit consists of cash merger
   consideration of $    per unit and a special distribution in cash estimated
   as of      , 1999 to be $    per unit.]

                                       2
<PAGE>

Q: How was the amount that I will receive for my limited partner units in the
   Partnership determined?

A: The merger consideration into which each limited partner unit in the
   Partnership will be converted has been determined based upon an allocation
   analysis prepared by Stanger & Co., the independent advisor to the McNeil
   Partnerships. Stanger & Co. allocated the aggregate consideration in the
   transaction among the various interests, rights and assets being acquired
   by WXI/McN Realty in the transaction. This allocation was based on, among
   other things:

  . the relative aggregate values of the real estate assets of each McNeil
    Partnership as determined by Stanger & Co.,

  . the value of the management assets and other assets of McREMI as
    determined by Stanger & Co.,

  . percentages jointly negotiated by Stanger & Co., in consultation with
    Eastdil Realty Company, and WXI/McN Realty governing the allocation of
    the portion of the aggregate consideration allocated to the McNeil
    Partnerships among the McNeil Partnerships, and

  . the amounts due to the McNeil Affiliates as reflected on the financial
    statements of the McNeil Partnerships as of      , 1999.

  The aggregate amount of the special distribution which will be distributed
  to limited partners of the Partnership will be calculated in accordance
  with the Master Agreement and will be based upon an estimated modified net
  working capital balance of the Partnership as of the closing date. The per
  unit amount of the special distribution will be determined in accordance
  with the provisions of the Partnership's limited partnership agreement
  governing distributions of surplus cash, except that the general partner of
  the Partnership will not receive any part of the special distribution.

Q: Will I continue to receive distributions from the Partnership?

A: Following the merger of the Partnership, you will have no right to receive
   distributions other than unpaid distributions that were declared prior to
   the merger of the Partnership, if any, and other than the special
   distribution, if any, of the Partnership as described above in the answer
   to the eighth question. If the Partnership does not participate in the
   transaction, you will continue to receive distributions, if any, in
   accordance with the Partnership's limited partnership agreement and in the
   discretion of McNeil Partners.

Q: Does the transaction require the vote of the limited partners?

A: Yes. Approval of the merger proposal by the limited partners is a condition
   to the Partnership's participation in the transaction. The affirmative vote
   of limited partners holding more than [for all except Funds XXI-XXIII: 50%
   of the limited partner units] [for Funds XXI-XXIII: 50% of each class of
   limited partner units] in the Partnership outstanding as of    , 1999 (the
   "record date") is required to approve the merger proposal. The record date
   is the date fixed by McNeil Partners to determine the limited partners
   entitled to vote at the meeting.

Q: If the limited partners of the Partnership approve the merger proposal, is
   it certain that the Partnership will participate in the transaction?

A: No. The Partnership's participation in the transaction is subject to
   several other closing conditions, including: the accuracy of the
   representations and warranties of the McNeil Partnerships and WXI/McN
   Realty contained in the Master Agreement; performance of obligations by the
   McNeil Partnerships and WXI/McN Realty under the Master Agreement;
   obtaining various consents and other approvals; the McNeil Partnerships
   having generally unencumbered, insurable title to each of their properties;
   and the McNeil Partnerships as a group having a specified minimum net
   operating income for the twelve months prior to the closing.

  Limited partners of the Partnership should be aware that the satisfaction
  or waiver of each of the closing conditions is a condition to the
  Partnership's participation in the transaction. Therefore, it is possible
  that the failure of one

                                       3
<PAGE>

  McNeil Partnership to satisfy a condition could cause the transaction to
  fail to close for all of the McNeil Partnerships.

  The parties to the Master Agreement also have the right to terminate the
  transaction in its entirety in specified circumstances, and the right to
  cause one or more McNeil Partnerships to be excluded from the transaction
  in specified circumstances and to proceed to close with the other McNeil
  Partnerships.

Q: What happens if I vote against the merger proposal?

A: If you vote against the merger proposal, but holders of more than [for all
   except Funds XXI-XXIII: 50% of the limited partner units] [for Funds XXI-
   XXIII: 50% of each class of limited partner units] in the Partnership
   outstanding as of the record date vote for the merger proposal and the
   Partnership participates in the transaction, you will receive an aggregate
   of approximately [for all except Funds XXI-XXIII: $    in cash for each of
   your limited partner units] [for Funds XXI-XXIII: $    in cash for each of
   your current income units and $    in cash for each of your growth/shelter
   units]. If you fail to return your proxy or mark "ABSTAIN" on your proxy,
   the effect will be the same as a vote against the merger proposal.
   [Additional disclosure for Funds XX--XXVI: If you do not vote for the
   merger proposal, you will be entitled to exercise dissenters' rights if the
   Partnership participates in the transaction and you follow specific
   procedures set forth in the California Revised Limited Partnership Act.]

Q: What happens if the Partnership participates in the transaction?

A: If the Partnership participates in the transaction, you will cease to own
   limited partner units in the Partnership and McNeil Partners will cease to
   be the general partner of the Partnership. Following the completion of the
   transaction, the Partnership will be wholly owned by WXI/McN Realty and its
   subsidiaries.

Q: What happens if the Partnership does not participate in the transaction?

A: If the Partnership does not participate in the transaction, the limited
   partners of the Partnership will continue to own limited partnerunits in
   the Partnership and McNeil Partners will continue to be the general partner
   of the Partnership. Because McNeil Partners is obligated under the
   Partnership's limited partnership agreement to use commercially reasonable
   efforts to complete the liquidation and termination of the Partnership by
   December 31, 1999, McNeil Partners will continue to explore alternative
   transactions to liquidate the Partnership if the Partnership does not
   participate in the transaction. There is no assurance, however, that if the
   Partnership does not participate in the transaction McNeil Partners will be
   able to arrange an alternative transaction involving the Partnership, or
   that any alternative transaction would result in limited partners receiving
   consideration of equal or greater value than the consideration which is
   estimated to be paid in the transaction. If the Partnership does not
   participate in the transaction, McREMI, or another property manager
   selected by McNeil Partners, will manage the Partnership's properties
   pending a liquidation.

Q: Do limited partners have dissenters' or appraisal rights?

A: [For Funds XX-XXVI: Yes. If you do not vote for the merger proposal, you
   will be entitled to exercise dissenters' rights if the Partnership
   participates in the transaction and you follow specific procedures set
   forth in the California Revised Limited Partnership Act.]
   [For Funds IX-XII, XIV, XV, XXVII: No. Limited partners in the Partnership
   are not entitled to exercise dissenters' rights or other rights of
   appraisal in connection with the merger proposal, although limited partners
   in certain other McNeil Partnerships do have such rights.]

Q: When do you expect the transaction to be completed?

A: We are working to complete the transaction as quickly as possible. We
   expect to complete the transaction within several days following the
   meeting.

Q: What are the tax consequences of the transaction to the limited partners of
   the Partnership?


                                       4
<PAGE>

A: Limited partners will recognize gain or loss on the conversion of their
   limited partner units into cash in the merger [additional disclosure for
   Funds XX-XXVI: or on receipt of cash pursuant to the exercise of
   dissenters' rights], depending on the tax basis in their units. The gain or
   loss will be treated as capital gain or capital loss. However, a portion of
   that gain or loss that is attributable to so-called "unrealized
   receivables" (which includes recapture of some depreciation deductions
   previously taken) and "inventory items" (as defined in Section 751 of the
   Internal Revenue Code of 1986, as amended) may be treated as ordinary
   income or ordinary loss.

   In general, the special distribution of cash will not be taxable and will
   be treated as a return of capital to each limited partner. This return of
   capital will reduce the limited partner's adjusted tax basis in its limited
   partner units in the Partnership to the extent of the return of capital
   and, therefore, may increase the amount of any gain or decrease the amount
   of any loss recognized by that limited partner on the conversion of its
   limited partner interests into cash in the merger. To the extent that the
   special distribution received by a limited partner exceeds that limited
   partner's adjusted tax basis in all of its limited partner units, that
   excess will be taxable and will be treated as capital gain.

   Limited partners should consult their respective tax advisors as to the
   particular tax consequences of the transaction.

Q: When will I receive my final Schedule K-1?

A: The Partnership plans to deliver Schedule K-1s (Form 1065) to the limited
   partners within 15 days of the fourth month following the closing date of
   the transaction, unless the Partnership finds that it will require
   additional time to complete the final return. If this situation occurs, the
   Partnership will apply for an extension from the IRS and will notify the
   limited partners of the extension request and the projected timing of the
   mailing of the Schedule K-1.

Q: How is the Schofield litigation related to this transaction?

A: In August 1995, limited partners of some of the McNeil Partnerships filed
   class actions, derivative actions or both on behalf of the limited partners
   of those McNeil Partnerships. These actions were consolidated in late 1996
   under the action, Schofield et al. v. McNeil Partners, L.P. et al.,
   Superior Court of the State of California for the County of Los Angeles. In
   September 1998, the parties signed a Stipulation of Settlement providing,
   among other things, for a commitment by McNeil Partners and its affiliates
   to market the McNeil Partnerships for sale, together with McREMI, through a
   fair and impartial bidding process overseen by a national investment
   banking firm. This transaction is, in part, a result of that process. On
   July 8, 1999, the court granted final approval of the settlement and
   dismissed the action.

Q: What other matters will be voted on at the meeting?

A: We do not expect to ask you to vote on any other matters at the meeting.
   However, if a motion is made to adjourn or postpone the meeting, you may
   also be asked to vote on the adjournment or postponement of the meeting.

Q: What do I need to do now?

A: Please complete, date and sign your proxy and then return it in the
   enclosed envelope as soon as possible so that your limited partner units
   may be represented at the meeting.

Q: Can I fax my proxy vote?

A: Yes. First complete, date and sign your proxy. Then fax the proxy to 1-800-
   XXX-XXXX.

Q: Should I send in my limited partner unit certificates?

A: No. After the merger of the Partnership is completed, we will send you a
   letter of transmittal and written instructions for exchanging your
   certificates for the merger consideration.

Q: When can I expect to receive payment for my limited partner units?

A: After the consummation of the merger, the Partnership will send you a
   letter of transmittal. Upon receipt of a completed letter of

                                       5
<PAGE>

   transmittal and your certificates from you, the payment agent will mail your
   check to you.

Q: May I change my vote after I have mailed my signed proxy?

A: Yes. Just send in a later dated, signed proxy prior to the meeting or attend
   the meeting and vote in person. Taking either of these steps will revoke any
   previously submitted proxy. You may also revoke any previously submitted
   proxy by written notice to McNeil Partners prior to the meeting.

The meeting (page  )

   The meeting will be held at      , local time, on       , 1999, at  . At the
meeting, limited partners of the Partnership will be asked to consider and vote
on the merger proposal.

   McNeil Partners does not expect to ask the limited partners of the
Partnership to vote on any other matters at the meeting. However, if a motion
is made to adjourn or postpone the meeting, the limited partners of the
Partnership may also be asked to vote on the adjournment or postponement of the
meeting. The Master Agreement provides that McNeil Partners will recommend the
adjournment of the meeting for ten days if on the date of the meeting the
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 for the merger proposal, will constitute a sufficient number of votes to
approve the merger proposal. However, if limited partners

                                       12
<PAGE>

holding greater than a majority of the outstanding limited partner units in the
Partnership have indicated their intention to vote against, and have submitted
duly executed proxies voting against, the merger proposal, the Master Agreement
does not require McNeil Partners to recommend adjournment of the meeting.

Record date; voting power (page  )

   McNeil Partners has fixed the close of business on      , 1999, as the
record date for determination of the limited partners entitled to notice of and
to vote at the meeting and any adjournment or postponement of the meeting. As
of the record date, there were    limited partner units in the Partnership
issued and outstanding and held of record by approximately    holders of
record. Holders of record of limited partner units in the Partnership are
entitled to one vote for each unit that they hold on the merger proposal and
any other matter that may properly come before the meeting. [Additional
disclosure for Funds XXI-XXIII: Holders of current income units and holders of
growth/shelter units will vote separately on the merger proposal.]

Quorum; vote required (page  )

   The necessary quorum for the transaction of business at the meeting is the
presence in person or by proxy of limited partners holding [for all except
Funds XXI-XXIII: a majority of the limited partner units] [for Funds XXI-XXIII:
a majority of each class of limited partner units] in the Partnership
outstanding on the record date. For purposes of determining the presence of a
quorum, abstentions will be counted by McNeil Partners as not present at the
meeting.

   The affirmative vote of limited partners holding greater than [for all
except Funds XXI-XXIII: 50% of the limited partner units] [for Funds XXI-XXIII:
50% of each class of limited partner units] in the Partnership outstanding on
the record date is required to approve the merger proposal. [Additional
disclosure for Funds IX-XI, XIV, XV, XX, XXV-XXVII: As of the record date,
McNeil Partners and some of its affiliates, other than the Partnership,
beneficially owned an aggregate of      limited partner units in the
Partnership, representing in the aggregate approximately  % of the limited
partner units outstanding on the record date. McNeil Partners and these
affiliates intend to vote all of the limited partner units beneficially owned
by them in the Partnership for the merger proposal.] [Additional disclosure for
Fund XXIII: As of the record date, McNeil Partners beneficially owned an
aggregate of       growth/shelter units in the Partnership, representing in the
aggregate approximately   % of the growth/shelter units outstanding on the
record date. McNeil Partners intends to vote all of the limited partner units
in the Partnership beneficially owned by it for the merger proposal.]

   If you fail to return your proxy or mark "ABSTAIN" on your proxy, the effect
will be the same as a vote against the merger proposal. If you sign and return
your proxy but do not give instructions on your proxy, your limited partner
units will be voted for the merger proposal.

   Approval of the merger proposal by the limited partners of the Partnership
is a condition to the Partnership's participation in the transaction. See "--
Conditions to closing." Therefore, if we do not receive votes for the merger
proposal from limited partners holding greater than [for all except Funds XXI-
XXIII: 50% of the limited partner units] [for Funds XXI-XXIII: 50% of each
class of limited partner units] in the Partnership, the merger proposal will
not be approved and the Partnership will not participate in the transaction.

Changing your vote (page  )

   You may revoke your proxy at any time before it is voted at the meeting (1)
by sending in a later dated, signed proxy, (2) by written notice to McNeil
Partners or (3) by attending the meeting and voting in person.

Purposes and reasons for the transaction (page  )

   The purpose of the transaction is for WXI/McN Realty to acquire the general
partner interests and limited partner interests in the McNeil Partnerships,
assets of McNeil Partners related to the McNeil Partnerships and

                                       13
<PAGE>

certain assets of McREMI, while providing the limited partners of the McNeil
Partnerships with the opportunity to liquidate their investment in the McNeil
Partnerships for cash at a price and on terms that the McNeil General Partners
believe are fair to and in the best interests of the limited partners of that
McNeil Partnership. See "--Position of McNeil Partners and Robert A. McNeil
regarding the transaction." The McNeil General Partners also believe that the
transaction will provide more immediate liquidity to the limited partners of
each of the McNeil Partnerships than would have been obtainable had each of the
McNeil Partnerships been liquidated on a property by property basis. The McNeil
Investors board of directors has unanimously determined that the merger
proposal is fair to and in the best interests of each of the McNeil
Partnerships and its limited partners. In addition, McNeil Partners believes
that the structure of the transaction will allow it to meet its obligations to
liquidate the public McNeil Partnerships in a manner that is in the best
interests of the limited partners of each of the public McNeil Partnerships.
Moreover, counsel to the plaintiffs in the Schofield litigation has reviewed
the terms of the transaction and oversaw the auction process.

Structure of the transaction (page  )

   The following figures depict the structure of the transaction and the
ownership interests of the parties to the transaction at different stages of
the transaction.

   The following figures assume that each of the McNeil Partnerships approves
the merger proposal applicable to that McNeil Partnership and participates in
the transaction. In the event that a particular McNeil Partnership does not
approve the merger proposal or does not participate in the transaction, it will
not be included in the transaction and the transactions depicted below with
respect to that McNeil Partnership will not occur. In the event that a
particular McNeil Partnership does not participate in the transaction, none of
the transactions relating to the other McNeil Partnerships will be affected.

 The mergers

   Immediately following the replacement of the general partner of each of the
McNeil Partnerships, separate newly formed limited partnerships directly or
indirectly wholly owned by WXI/McN Realty will be simultaneously merged with
and into each of the McNeil Partnerships, other than the Affiliated McNeil
Partnerships. The limited partners of each of the McNeil Partnerships, other
than the Affiliated McNeil Partnerships, will receive cash consideration in the
transaction. The aggregate amount to be received in the transaction per limited
partner unit in each of the McNeil Partnerships consists of two components--the
merger consideration and a special distribution.

   The aggregate amount to be received in the transaction by limited partners
in the Partnership is estimated at [for all except Funds XXI-XXIII: $   in cash
for each limited partner unit.] [for Funds XXI-XXIII: $   in cash for each
current income unit and $   in cash for each growth/shelter unit.] [For all
except Funds XXI-XXIII: The amount for each limited partner unit consists of
merger consideration of $   per unit and a special cash distribution estimated
as of       , 1999 at $   per unit.] [For Funds XXI-XXIII: The amount for each
current income unit consists of merger consideration of $   per unit and a
special cash distribution estimated as of     , 1999 at $   per unit. The
amount for each growth/shelter unit consists of merger consideration of $  per
unit and a special cash distribution estimated as of       , 1999 at $   per
unit.]

   The merger consideration is equal to the amount of the aggregate
consideration in the transaction allocated by Stanger & Co. to the limited
partner units in each McNeil Partnership. For each participating McNeil
Partnership, other than the Affiliated McNeil Partnerships, each limited
partner unit in that McNeil Partnership will be converted at the effective time
of the merger of that McNeil Partnership into the right to receive the per unit
merger consideration for that McNeil Partnership.

   In addition, if a participating McNeil Partnership has a positive net
working capital balance on the closing date of the transaction, that
participating McNeil Partnership will declare a special distribution in cash to
its limited partners. The amount of the special distribution will be calculated
in accordance with the terms of the Master Agreement and will be based upon a
modified net working capital balance of that McNeil Partnership as of the
closing date. This special distribution will be made in accordance with the
provisions of that McNeil Partnership's limited partnership agreement governing
distributions of surplus cash, except that the general partner of that McNeil
Partnership will not receive any part of the special distribution.

   McNeil Partners will receive membership interests in and credit for a
capital contribution to WXI/McN Realty in exchange for its contributions to
WXI/McN Realty and WXI/McN Realty's subsidiaries of its general partner
interests in each of the participating McNeil Partnerships, its limited partner
interests in the Affiliated McNeil Partnerships, assets of McNeil Partners
related to the McNeil Partnerships and certain assets of McREMI.

   Following the mergers, each of the participating McNeil Partnerships will
continue as the surviving limited partnership and a directly and/or indirectly
wholly owned subsidiary of WXI/McN Realty.

certain assets of McREMI. Each McNeil Partnership's participation in the
transaction is subject to the requisite approval of its limited partners. As a
result of the transaction, each participating McNeil Partnership will become a
direct and/or indirect wholly owned subsidiary of WXI/McN Realty and a separate
direct or indirect wholly owned subsidiary of WXI/McN Realty will own and
operate the assets of McREMI contributed to WXI/McN Realty and its
subsidiaries. Following completion of the transaction, the current limited
partners of a participating McNeil Partnership will no longer have any interest
in, and will not be limited partners of, that McNeil Partnership and,
therefore, will not participate in that McNeil Partnership's future earnings
and potential growth. Following the completion of the transaction, the limited
partner units of each of the public McNeil Partnerships which participates in
the transaction will cease to be a reporting company and will cease to be
registered under the Securities Exchange Act of 1934, as amended.

   The limited partners of each of the participating McNeil Partnerships, other
than the Affiliated McNeil Partnerships, will receive only cash consideration
in the transaction. The aggregate amount to be received in the transaction per
limited partner unit in each of the McNeil Partnerships consists of two
components--the merger consideration and a special distribution.

   The aggregate amount to be received in the transaction by limited partners
of the Partnership is estimated at [for all except Funds XXI-XXIII: $   in cash
for each limited partner unit.] [for Funds XXI-XXIII: $    in cash for each
current income unit and $   in cash for each growth/shelter unit.] [For all
except Funds XXI-XXIII: The amount for each limited partner unit consists of
merger consideration of $   per unit and a special cash distribution estimated
as of    , 1999 at $    per unit.] [For Funds XXI-XXIII: The amount for each
current income unit consists of merger consideration of $   per unit and a
special cash distribution estimated as of    , 1999 at $   per unit. The amount
for each growth/shelter unit consists of merger consideration of $   per unit
and a special cash distribution estimated as of    , 1999 at $   per unit.]

   The merger consideration is equal to the amount of the aggregate
consideration in the transaction allocated by Stanger & Co. to the limited
partner units in each McNeil Partnership. For each participating McNeil
Partnership, other than the Affiliated McNeil Partnerships, each limited
partner unit in that McNeil Partnership will be converted at the effective time
of the merger of that McNeil Partnership into the right to receive the per unit
merger consideration for that McNeil Partnership.

   In addition, if a participating McNeil Partnership has a positive net
working capital balance on the closing date of the transaction, that
participating McNeil Partnership will declare a special distribution in cash to
its limited partners. The amount of the special distribution will be calculated
in accordance with the terms of the Master Agreement and will be based upon a
modified net working capital balance of that McNeil Partnership as of the
closing date. This special distribution will be made in accordance with the
provisions of the Partnership's limited partnership agreement governing
distributions of surplus cash, except that the general partner of that McNeil
Partnership will not receive any part of the special distribution.

   McNeil Partners will receive membership interests in and credit for a
capital contribution to WXI/McN Realty in exchange for its contributions to
WXI/McN Realty and WXI/McN Realty's subsidiaries of its general partner
interests in each of the participating McNeil Partnerships, the limited partner
interests in the Affiliated McNeil Partnerships, assets of McNeil Partners
related to the McNeil Partnerships and certain assets of McREMI. The amount of
the capital contribution by McNeil Partners to WXI/McN Realty in exchange for
these contributions will be equal to the aggregate consideration allocated by
Stanger & Co. to the interests, rights and assets being contributed by McNeil
Partners in these contributions. McNeil Partners also may make cash
contributions to WXI/McN Realty under some circumstances and some fees,
expenses and disbursements

                                       25
<PAGE>

incurred and paid by the McNeil Affiliates in connection with the transaction
will be treated as a contribution in-kind to WXI/McN Realty. McNeil Partners
will receive membership interests in WXI/McN Realty and credit for a capital
contribution to WXI/McN Realty in the amount of any cash contribution or any
such contribution in-kind to WXI/McN Realty. See "Special Factors--Interests of
certain persons in matters to be acted upon; conflicts of interest--Equity
interest of McNeil Partners in WXI/McN Realty."

   The relationship between McNeil Partners and WXI/McN Realty's managing
member after the effective time of the mergers will be governed by the first
amended and restated limited liability company operating agreement of WXI/McN
Realty (the "WXI/McN Realty Operating Agreement") to be entered into between
McNeil Partners and WXI/McN Realty's managing member at the effective time of
the merger. See "WXI/McN Realty Operating Agreement." The form of the WXI/McN
Realty Operating Agreement is attached to this Proxy Statement as Appendix B
and is incorporated in this Proxy Statement by reference.

Recommendations of the special committee and the McNeil Investors board of
directors (page )

 Recommendations of the special committee

   On May 7, 1999, following preliminary discussions with Whitehall, the McNeil
Investors board of directors formed a special committee of the McNeil Investors
board of directors, consisting of one independent director, (1) to participate,
through its legal counsel and financial advisor, in negotiating the forms,
terms and conditions of the definitive agreements with respect to the
transaction, and (2) with the assistance of its legal counsel and financial
advisor, to review and pass upon the terms of the transaction on behalf of the
limited partners of the McNeil Partnerships. See "Special Factors--Background
of the transaction--Background of the auction process--Appointment of the
special committee."

   The special committee:

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of each of the McNeil Partnerships, and

  . recommended to the McNeil Investors board of directors the approval of
    the merger proposal.

   In making its determination, the special committee relied on a fairness
opinion delivered to the McNeil Investors board of directors by Stanger & Co.
on behalf of the McNeil Partnerships and a fairness opinion delivered to the
special committee by Eastdil Realty Company L.L.C., the financial advisor to
the special committee, to the effect that each of the aggregate consideration,
the allocations of the aggregate consideration and the estimated aggregate
amount to be received with respect to each limited partner unit in each of the
McNeil Partnerships is fair from a financial point of view to the holders of
each class of limited partner units in each of the McNeil Partnerships.

 Recommendations of the McNeil Investors board of directors

   The McNeil Investors board of directors:

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of each of the McNeil Partnerships,

  . approved the merger proposal, and

  . determined to recommend to the limited partners of each of the McNeil
    Partnerships that they approve the merger proposal.

   In making its determinations, the McNeil Investors board of directors relied
on the recommendation of the special committee and on a fairness opinion
delivered to the McNeil Investors board of directors by Stanger & Co. on behalf
of the McNeil Partnerships to the effect that each of the aggregate
consideration, the allocations of the aggregate consideration and the estimated
aggregate amount to be received with respect to each limited partner unit in
each of the McNeil Partnerships is fair from a financial point of view to the
holders of each class of limited partner units in each of the McNeil
Partnerships.

Factors considered by the McNeil Investors board of directors and the special
committee (page  )

   In reaching their determination that the merger proposal is fair to, and in
the best interests of, limited partners of each of the McNeil Partnerships and
in determining to recommend approval of the merger proposal, the McNeil
Investors board of directors and the special committee considered a number of
factors. The material supporting factors considered were:

  . The transaction satisfied McNeil Partners' obligations under the limited
    partnership agreements of each of the public McNeil Partnerships to use
    commercially reasonable efforts to complete the liquidation and
    termination of the public McNeil Partnerships by December 31, 1999. The
    transaction also satisfied the commitment of McNeil Partners in a
    settlement of the Schofield litigation to market the McNeil Partnerships
    for sale, together with McREMI, through a fair and impartial bidding
    process overseen by a national investment banking firm.

  . The transaction was structured to maximize the value of each of the
    McNeil Partnerships. PaineWebber, Incorporated, the McNeil Partnerships'
    exclusive financial advisor, advised McNeil Partners that the highest and
    best price for the McNeil Partnerships, and therefore the greatest
    distribution to the limited partners of each of the McNeil Partnerships,
    would likely be achieved by offering for sale the McNeil Partnerships,
    McNeil Partners, McNeil Investors and McREMI as an entire portfolio on an
    all-or-none basis, a structure that would allow a potential purchaser to
    acquire a large portfolio of real estate managed by a competent and
    experienced management team with a demonstrated track record of operating
    the properties over an extended period of time. This was particularly
    important because of the geographic diversity of the properties and the
    age of the improvements on most of the properties. In addition, the
    structure selected eliminated the difficulties that would have been
    encountered if prospective purchasers were allowed to purchase the more
    attractive properties, leaving behind the less attractive properties that
    could prove time consuming and expensive for an individual McNeil
    Partnership to liquidate.

  . The manner in which the auction process with respect to the proposed
    transaction was structured, the method and criteria for selection of the
    potential bidders, the detailed information with respect to the
    properties furnished to the prospective bidders, the conduct of the
    initial and final bid stages of the auction process and the lengthy
    negotiations that were conducted with the final bidders ultimately
    leading to WXI/McN Realty as the prospective purchaser.

  . WXI/McN Realty has agreed to an aggregate purchase price for all of the
    McNeil Partnerships and the assets being acquired in the transaction. The
    special committee took into account that Stanger & Co., the independent
    advisor to the McNeil Partnerships, made the following allocations: (1)
    the allocation of the aggregate consideration between the management
    assets of McREMI, on the one hand, and the McNeil Partnerships as a
    group, on the other hand; (2) the allocation of the aggregate
    consideration to each individual McNeil Partnership; and (3) the
    allocation of the aggregate consideration allocated to each individual
    McNeil Partnership among the general partner interest in that McNeil
    Partnership, other assets of McREMI related to that McNeil Partnership
    and each class of limited partner units in that McNeil Partnership.

  . If a participating McNeil Partnership's net working capital balance,
    calculated on the closing date of the transaction in accordance with the
    Master Agreement, is greater than zero, that McNeil Partnership will make
    a special cash distribution to its limited partners on the closing date
    equal to the amount of the positive net working capital balance.

  . The opinions of Stanger & Co. to the effect that each of the aggregate
    consideration, the allocations of the aggregate consideration and the
    estimated per unit aggregate amount to be received with respect to each
    class of limited partners of each of the McNeil Partnerships is fair from
    a financial point of view to the holders of each class of limited partner
    units in each of the McNeil Partnerships.


                                       27
<PAGE>

  . The Stanger & Co. analysis concluded that the estimated per unit
    aggregate amount, including both the merger consideration and the special
    distribution, to be received with respect to each class of limited
    partners of each of the McNeil Partnerships upon the closing of the
    transaction was equal to or greater than (1) the net asset value of that
    unit, (2) the going concern value of that unit and (3) the liquidation
    value of that unit.

  . The opinions of Eastdil Realty Company to the effect that each of the
    aggregate consideration, the allocations of the aggregate consideration
    and the estimated per unit aggregate amount to be received with respect
    to each class of limited partners of each of the McNeil Partnerships is
    fair from a financial point of view to the holders of each class of
    limited partner units in each of the McNeil Partnerships.

  . The presentation of Houlihan, Lokey, Howard & Zukin Capital, the
    financial advisor to the McNeil Affiliates, that concluded that the total
    consideration that would be fairly allocable to McREMI as determined by
    Stanger & Co. was at or below the low end of the range of value estimated
    by Houlihan, Lokey, Howard & Zukin Capital.

  . The fact that the lawyers representing the plaintiffs in the Schofield
    litigation, in connection with settlement proceedings relating to that
    litigation, oversaw the auction process, including the allocation
    analysis rendered by Stanger & Co.

  . The identity of the proposed purchaser and its affiliates and the ability
    of WXI/McN Realty to consummate the transaction on the terms specified in
    the Master Agreement.

  . The provisions in the Master Agreement allowing each of the McNeil
    Partnerships to terminate its participation in the transaction if, in the
    exercise of the good faith judgment of the general partner as to its
    fiduciary duties to its limited partners, the general partner of that
    McNeil Partnership determined that termination was required by reason of
    a superior acquisition proposal being made by a third party for that
    McNeil Partnership. The special committee recognized that any such
    termination would require the payment by that terminating McNeil
    Partnership to WXI/McN Realty of a break-up fee and certain reimbursable
    expenses.

  . The terms and conditions of the Master Agreement, taken as a whole, were
    favorable to the limited partners of the McNeil Partnerships and thus
    supported the conclusion that the merger proposal is fair to, and in the
    best interests of, the limited partners of the McNeil Partnerships.

  . In allocating the aggregate consideration, Stanger & Co. took the
    position that the deficit restoration obligations of the general partners
    of the McNeil Partnerships were required to be paid to the McNeil
    Partnerships. As a result, the aggregate consideration allocated by
    Stanger & Co. to the general partner interests in each of the McNeil
    Partnerships is net of the estimated deficit restoration obligation with
    respect to that McNeil Partnership. The aggregate amount of the estimated
    deficit restoration obligation payable in respect of all of the McNeil
    Partnerships, based upon a hypothetical sale of properties and
    liquidation of the McNeil Partnerships at March 31, 1999, is
    approximately $6,439,000.

  . In allocating the aggregate consideration, Stanger & Co. took the
    position that no asset disposition fees were payable by any of the McNeil
    Partnerships to the McNeil General Partners as a result of the
    transaction. In a liquidation, the limited partnership agreements of some
    of the McNeil Partnerships provide that McNeil Partners is entitled to
    receive an asset disposition fee equal to 3% of the gross sales price of
    each property sold in connection with a liquidation of that McNeil
    Partnership. No asset disposition fees will be paid by any of the McNeil
    Partnerships as a result of the transaction.

  . Each of the McNeil General Partners has agreed to irrevocably,
    unconditionally and absolutely waive any and all rights it may have to
    indemnification, contribution or reimbursement from any of the
    participating McNeil Partnerships with respect to those matters for which
    McNeil Partners has agreed to indemnify WXI/McN Realty's managing member
    and some of its affiliates.


                                       28

  . Upon the completion of the transaction, the limited partners of the
    participating McNeil Partnerships, other than the Affiliated McNeil
    Partnerships, would receive cash in exchange for their limited partner
    units and, accordingly, those limited partners would no longer bear the
    risks inherent in the ownership of real property.

  . Commencing with the tax year following the tax year in which the closing
    of the transaction occurs, the limited partners of the participating
    McNeil Partnerships will no longer need to include in their federal and
    state income tax returns the various items of income, loss, deduction and
    credit as previously reported on Schedule K-1s delivered by the
    participating McNeil Partnerships.

  . As to each McNeil Partnership, approval of the merger proposal requires
    the affirmative vote of limited partners holding greater than 50% of each
    class of limited partner units in that McNeil Partnership outstanding as
    of the record date.

  . Under the California Revised Limited Partnership Act, a limited partner
    of some of the McNeil Partnerships [additional disclosure for Funds XX-
    XXVII, including the Partnership,] who does not wish to accept the merger
    consideration may dissent from the merger proposal and require that
    McNeil Partnership to purchase for cash, at their fair market value, the
    limited partner units owned by that limited partner, if that McNeil
    Partnership participates in the transaction, the limited partner does not
    vote for the merger proposal and the limited partner follows specific
    procedures set forth in the California Revised Limited Partnership Act.

The material negative factors considered were:

  . Following the transaction, the limited partners of each participating
    McNeil Partnership, other than the Affiliated McNeil Partnerships, will
    cease to participate in future earnings or growth, if any, of that McNeil
    Partnership or benefit from increases, if any, in the value of that
    McNeil Partnership.

  . The transaction involves the entire McNeil portfolio, including all of
    the McNeil Partnerships, assets of McNeil Partners related to the McNeil
    Partnerships and certain assets of McREMI. At the commencement of
    PaineWebber's engagement, McNeil Partners determined to structure the
    transaction to include certain assets of McREMI, based on PaineWebber's
    belief at that time that the highest price for the McNeil Partnerships,
    and therefore the greatest distribution to the limited partners of each
    of the McNeil Partnerships, would likely be achieved by offering the
    McNeil Partnerships and McREMI as an entire portfolio on an all-or-none
    basis. However, it is possible that the limited partners of a McNeil
    Partnership could have received more consideration than what they will
    otherwise receive in the proposed transaction with WXI/McN Realty if that
    McNeil Partnership were to be sold or liquidated in a transaction
    separate from a transaction involving other McNeil Partnerships and/or
    the assets of McREMI.

  . The limited partners of each participating McNeil Partnership will forego
    alternatives to the transaction. These alternatives include a separate
    sale of all of the assets of that McNeil Partnership and subsequent
    liquidation of that McNeil Partnership or the continuation of that McNeil
    Partnership.

  . There are numerous conditions to WXI/McN Realty's and Sellers'
    obligations to consummate the transaction. No assurance can be given that
    the transaction will be consummated.

  . The Master Agreement provides that in some circumstances WXI/McN Realty
    will receive a break-up fee, calculated on a partnership by partnership
    basis, up to an aggregate maximum of $18.0 million, if the Master
    Agreement is terminated. The amount of the break-up fee payable by the
    Partnership is $    . The obligation of a McNeil Partnership to pay a
    break-up fee may discourage third party offers for that particular McNeil
    Partnership and may adversely affect the ability of that McNeil
    Partnership to engage in another transaction following termination of the
    Master Agreement in respect of that McNeil Partnership. In addition, a
    McNeil Partnership may be obligated to pay a break-up fee

                                       29
<PAGE>

   even if it has not entered into a definitive agreement for, or
   consummated, another transaction. As a result, payment of the break-up fee
   may have an adverse impact on the financial condition of that McNeil
   Partnership.

  . McNeil Partners has actual or potential conflicts of interest in
    connection with recommending the approval of the merger proposal to the
    limited partners of the McNeil Partnerships.

  . Each of the McNeil Partnerships did not have separate representation in
    the transaction. In structuring the transaction, the special committee
    represented the interests of the limited partners of all of the McNeil
    Partnerships as a group and Stanger & Co. served as independent advisor
    to all of the McNeil Partnerships. If separate representation had been
    arranged for each McNeil Partnership, issues unique to the value of a
    given McNeil Partnership might have received greater attention during the
    structuring of the transaction and the terms of the transaction might
    have been different with respect to that McNeil Partnership.

  . If limited partners owning more than 50% of each class of limited partner
    units in a McNeil Partnership vote for the merger proposal, their
    approval will bind all limited partners of that McNeil Partnership.
    Therefore, a limited partner of a McNeil Partnership may vote against the
    merger proposal and nevertheless have its limited partner units converted
    into the right to receive cash in the transaction if the requisite vote
    of the limited partners of that McNeil Partnership is obtained.

  . The transaction, as structured, will allow McNeil Partners to make the
    contributions of its interests in the McNeil Partnerships and the assets
    of McNeil Partners and McREMI being contributed to WXI/McN Realty on a
    tax-free basis and to defer substantial tax liability that would be
    incurred if there were to be a taxable sale of the properties. In
    contrast, limited partners will recognize gain or loss on the conversion
    of their limited partner units into cash in the merger [additional
    disclosure for Funds XX-XXVI: or on receipt of cash pursuant to the
    exercise of dissenters' rights]. In general, the special distribution
    will not be taxable and will be treated as a return of capital to the
    limited partner; provided, however, that to the extent that the special
    distribution received by a limited partner exceeds that limited partner's
    adjusted tax basis in all of its limited partner units that excess will
    be taxable and will be treated as capital gain.

  .In determining whether the requisite vote of the limited partners of a
   McNeil Partnership has been obtained, limited partner units held by McNeil
   Partners and its affiliates will not be excluded. McNeil Partners and its
   affiliates intend to vote all of the limited partner units beneficially
   owned by them in each of the McNeil Partnerships for the merger proposal
   with respect to that McNeil Partnership. [Additional disclosure for Funds
   IX-XI, XIV, XV, XX, XXV-XXVII: As of the record date, McNeil Partners and
   some of its affiliates beneficially owned an aggregate of    limited
   partner units in the Partnership, representing in the aggregate
   approximately  % of the limited partner units in the Partnership
   outstanding as of the record date.] [Additional disclosure for Fund XXIII:
   As of the record date, NcNeil Partners beneficially owned an aggregate of
       growth/shelter units in the Partnership, representing in the aggregate
   approximately % of the growth/shelter units outstanding as of the record
   date.]

  . Limited partners of some of the McNeil Partnerships [additional
    disclosure for Funds IX-XII, XIV, XV, XXVII:, including the Partnership,]
    do not have any dissenters' rights or other rights of appraisal, under
    the state law which governs those McNeil Partnerships, the limited
    partnership agreements of those McNeil Partnerships or otherwise, in
    connection with the merger proposal. Therefore, dissenting limited
    partners of those McNeil Partnerships do not have the right to have their
    limited partner units appraised if they disapprove of the action of the
    limited partners that voted for the merger proposal. The limited partners
    of other McNeil Partnerships [additional disclosure for Funds XX-XXVI:,
    including the Partnership,] are entitled to the benefits of dissenters'
    rights as provided under applicable state law.

   In the views of the special committee and the McNeil Investors board of
directors, these countervailing factors were not sufficient, either
individually or in the aggregate, to outweigh the benefits of the proposed
transaction to the limited partners of the McNeil Partnerships.


                                       30
<PAGE>

   In view of the wide variety of factors considered in connection with its
evaluation of the transaction and the merger proposal, neither the special
committee nor the McNeil Investors board of directors found it practicable to,
and did not attempt to, quantify, rank or otherwise assign relative weights to
specific factors it considered in reaching its determination and
recommendation.

Position of McNeil Partners and Robert A. McNeil regarding the transaction
(page   )

   Each of McNeil Partners and Robert A. McNeil believes that the merger
proposal is fair to the limited partners of each of the McNeil Partnerships.
These beliefs are based on the determinations of the McNeil Investors board of
directors, the determination and recommendation of the special committee, the
factors that were considered by the special committee and the fairness opinions
delivered to the McNeil Investors board of directors by Stanger & Co. on behalf
of the McNeil Partnerships and the opinions delivered to the special committee
by Eastdil Realty Company.

   McNeil Partners and Robert A. McNeil have each adopted the analyses of the
special committee and the McNeil Investors board of directors in support of
their beliefs. Robert A. McNeil is the Co-Chairman of the McNeil Investors
board of directors and the sole stockholder of McNeil Investors and
participated in the deliberations of the McNeil Investors board of directors.
McNeil Investors is the general partner of McNeil Partners and therefore has
the power to take action on behalf of and make decisions on behalf of McNeil
Partners. As disclosed in the section entitled "Special Factors--Interests of
certain persons in matters to be acted upon; conflicts of interest," each of
McNeil Partners and Robert A. McNeil has a financial interest in the
transaction and interests in the transaction that differ from those of the
Partnership's limited partners.

Allocation of the aggregate consideration in the transaction (page  )

   The aggregate consideration in the transaction, including all outstanding
mortgage debt of the McNeil Partnerships, is $644,439,803. The Master Agreement
provides that at the effective time of the mergers, all outstanding mortgage
debt of the participating McNeil Partnerships will either be repaid by WXI/McN
Realty or will remain outstanding following the effective time of the mergers
until its expiration or prepayment, in each case as provided in the Master
Agreement. See "The Master Agreement--Aggregate consideration--Prepayment and
assumption of mortgage debt."

                                       32

   Stanger & Co. has allocated the aggregate consideration among (1) the
general partner interests in each of the McNeil Partnerships, (2) each class of
limited partner units in each of the McNeil Partnerships and (3) the management
assets and other assets of McREMI. The allocations and the methodology of the
allocations are described in more detail in "Special Factors--Opinions and
reports of financial advisors-- Allocation analysis and opinions of Stanger &
Co.--Stanger & Co. allocation analysis," and the dollar values of the
individual allocations are set forth in Table 2. The Master Agreement provides
that the allocations of the aggregate consideration by Stanger & Co. are
binding on Sellers and on WXI/McN Realty, its subsidiaries and affiliates.

   After the payment of estimated investment banking fees and expenses, an
aggregate of $35,236,000 has been allocated by Stanger & Co. to the management
assets of McREMI and an aggregate of $605,534,000 has been allocated by Stanger
& Co. to the McNeil Partnerships as a group. See "Partial McREMI Allocated
Value" and total "Allocated Partnership Value," respectively, in Table 2.

   The $605,534,000 allocated to the McNeil Partnerships as a group has further
been allocated among each of the individual McNeil Partnerships based on the
percentages agreed to between Stanger & Co., in consultation with Eastdil
Realty Company, and WXI/McN Realty and set forth in the Master Agreement. See
"Partnership Percentage" and "Allocated Partnership Value" in Table 2. The
amount of the aggregate consideration allocated to each individual McNeil
Partnership has further been allocated, after subtracting the principal balance
of all outstanding mortgage debt of that McNeil Partnership estimated as of
   , 1999, among the general partner interests in that McNeil Partnership (see
"GP Allocation Amount" in Table 2), the other assets of McREMI (see "Second
McREMI Allocated Value" in Table 2) and each class of limited partner units in
that McNeil Partnership (see "LP Allocation Amount" in Table 2). Stanger & Co.
also allocated the aggregate consideration allocated to each class of limited
partner units among the limited partner units in that class. See "Per Unit
Merger Consideration" in Table 2.

   Of the $605,534,000 allocated to the McNeil Partnerships as a group, an
aggregate of $   has been allocated by Stanger & Co. to the general partner
interests in the McNeil Partnerships, net of the estimated aggregate deficit
restoration obligations of the general partners of the McNeil Partnerships of
approximately $6,439,000. Of the $   allocated to the general partner interests
in the McNeil Partnerships, $   represents the general partners' proportionate
interests in the profits and losses of the McNeil Partnerships, based on the
general partners' capital contributions, and $   represents the rights and
other assets corresponding to the McNeil Partnerships which are being
contributed to WXI/McN Realty and its subsidiaries. In addition, an aggregate
of $    has been allocated by Stanger & Co. to the limited partner interests in
the Affiliated McNeil Partnerships, and an aggregate of $    has been allocated
by Stanger & Co. to the other assets of McREMI relating to the McNeil
Partnerships.

   Therefore, if all of the McNeil Partnerships approve the merger proposal, in
consideration for the interests, rights and assets being contributed by McNeil
Partners to WXI/McN Realty and its subsidiaries in the transaction, McNeil
Partners will receive membership interests in WXI/McN Realty and a credit for a
capital contribution to WXI/McN Realty in an amount equal to approximately
$   , representing the amount of the aggregate consideration allocated by
Stanger & Co. to the interests, rights and other assets being contributed by
McNeil Partners. See "Total Allocated McNeil Value" in Table 2.

   If less than all of the McNeil Partnerships participate in the transaction,
the portion of the aggregate consideration received by McNeil Partners will be
reduced by the amount of the aggregate consideration allocated by Stanger & Co.
to the interests, rights and assets related to any McNeil Partnerships that do
not participate in the transaction. See "MPLP Allocation Amount" in Table 2. In
addition, the amount of the aggregate consideration allocated to the management
assets of McREMI will be reduced in proportion to the aggregate "Partnership
Percentages" (see Table 2) of any McNeil Partnerships that do not participate
in the transaction. See "Partial McREMI Allocated Value" in Table 2.

Interests of certain persons in matters to be acted upon; conflicts of interest
(page  )

   In considering the recommendation of the McNeil Investors board of
directors, limited partners of the McNeil Partnerships should be aware that the
McNeil Affiliates have interests in the transaction or relationships that may
present actual or potential conflicts of interest in connection with the
transaction.

 Relationships among the McNeil Affiliates and the McNeil Partnerships

   The McNeil Affiliates and the McNeil Partnerships are affiliates as a result
of common ownership by Robert A. McNeil. McNeil Investors and McREMI also share
directors and executive officers. Robert A. McNeil, his wife Carole J. McNeil,
and Ron K. Taylor, President of McNeil Investors and McREMI, serve as the only
directors of McREMI and hold three of the four seats on the McNeil Investors
board of directors. The fourth director of McNeil Investors is Paul B. Fay,
Jr., an independent director. Mr. Fay also serves as the sole member of the
special committee.

 [Additional disclosure for Funds IX-XI, XIV, XV, XX, XXIII, XXV-XXVII:
 Ownership of limited partner units in the Partnership

   In addition to owning limited partner units in the Affiliated McNeil
Partnerships, McNeil Partners and some of its affiliates, other than the
Partnership, beneficially own limited partner units in the Partnership. McNeil
Partners and these affiliates intend to vote all of the limited partner units
in the Partnership beneficially owned by them for the merger proposal. If the
Partnership participates in the transaction, McNeil Partners and these
affiliates will receive the same aggregate amount per unit as each other
limited partner of the Partnership. Therefore, McNeil Partners and its
affiliates will receive an aggregate of $    in cash for the limited partner
units that they own in the Partnership if the Partnership participates in the
transaction.]

 Equity interest of McNeil Partners in WXI/McN Realty; WXI/McN Realty operating
agreement

   McNeil Partners will receive an aggregate of $   , if all of the McNeil
Partnerships participate in the transaction, in consideration for the
interests, rights and assets related to the participating McNeil Partnerships
being contributed by McNeil Partners to WXI/McN Realty and its subsidiaries in
the transaction. The consideration to be received by McNeil Partners for its
contributions to WXI/McN Realty will be paid in membership interests in WXI/McN
Realty. See "--Allocation of the aggregate consideration in the transaction."
At the effective time of the mergers, McNeil Partners also may make cash
contributions to WXI/McN Realty in exchange for additional membership interests
in WXI/McN Realty. In addition, some fees, expenses and disbursements incurred
and paid by the McNeil Affiliates in connection with the Master Agreement and
the other transaction documents will be treated as a contribution-in-kind to
WXI/McN Realty by McNeil Partners in exchange for additional membership
interests in WXI/McN Realty.

   McNeil Partners' membership interests in WXI/McN Realty will, subject to
certain limitations, entitle McNeil Partners to receive from WXI/McN Realty
distributions of net cash flow and net proceeds from capital transactions.
Consequently, McNeil Partners and the other McNeil Affiliates, through their
ownership of partnership interests in McNeil Partners, will have a significant
interest in WXI/McN Realty and, subject to certain limitations, will continue
to have the opportunity to participate in any future earnings growth and to
benefit from any increases in the value of the participating McNeil
Partnerships and their properties, and any other assets acquired by WXI/McN
Realty and its subsidiaries. However, the opportunity of the McNeil Affiliates
to participate in any future earnings growth of WXI/McN Realty is limited to
the percentage return on investment to which their membership interests entitle
them under the WXI/McN Realty Operating Agreement. This percentage return is
limited to 14% or 15% per annum, depending on the initial capital contribution
of McNeil Partners. See "WXI/MCN Realty Operating Agreement."

   Under the terms of the WXI/McN Realty Operating Agreement, following the
effective time of the merger, McNeil Partners also will have the right to
designate two of the five members of WXI/McN Realty's board of managers. The
remaining three members will be designated by WXI/McN Realty's managing member.
Action by WXI/McN Realty's board of managers will require the affirmative vote
of three of the five managers.

                                       34
<PAGE>

However, some actions of WXI/McN Realty's board of managers will require a
supermajority vote of four of the five managers. Therefore, McNeil Partners
will have a right to veto any transactions that require a supermajority vote of
WXI/McN Realty's board of managers. These transactions include:

  . material changes in WXI/McN Realty or its membership;

  . certain transactions with potential negative tax effects on McNeil
    Partners on or prior to the fifth anniversary of the closing date of the
    transaction; and

  . certain transactions with affiliates of WXI/McN Realty, WXI/McN Realty's
    managing member, Whitehall or Goldman, Sachs & Co.

 Retention agreements

   After the auction process began in late 1997, McNeil management became
concerned that certain officers and key employees would leave McREMI during the
sale process. To encourage these officers to remain employed with McREMI until
the completion of a sale transaction, in March 1998, McREMI entered into
retention agreements with these officers and employees. These agreements, as
amended, provide that upon the closing of the transaction, McREMI will be
obligated to pay those current officers and employees who remained employed by
McREMI until the closing date an aggregate of $      , of which $    will be
paid by McREMI and $    will be paid by the McNeil Partnerships, regardless of
whether any particular McNeil Partnership participates in the transaction. The
amounts payable under the retention agreements will be paid in lieu of other
amounts that would be payable in connection with the transaction under the
employment agreements that some of these individuals had entered into in their
capacities as officers of McREMI and McNeil Investors.

   One of the officers and key employees with whom McREMI entered into a
retention agreement is Ron K. Taylor. Mr. Taylor is a director and President of
McNeil Investors and McREMI, and in these capacities he participated in the
negotiation of the Master Agreement. Pursuant to his retention agreement, upon
the closing of the transaction, Mr. Taylor will be paid $       , of which
$     will be paid by McREMI and $    will be paid by the McNeil Partnerships
regardless of whether any particular McNeil Partnership participates.

Conditions to the transaction (page  )

   The obligations of each of WXI/McN Realty and Sellers to effect the
transaction are subject to the fulfillment or waiver of various customary
conditions. In addition, the obligations of each of WXI/McN Realty and Sellers
to effect the transaction are subject to the fulfillment or waiver by each
party to the Master Agreement of additional conditions, including, among
others:

  . approval of the merger proposal by holders of the requisite number of
    limited partner units in each participating McNeil Partnership, other
    than McNeil Summerhill I, L.P., whose approval has already been obtained;

  . settlement of the Schofield litigation (see "Special Factors--Background
    of the transaction--Background of the Schofield litigation"); and

  . determination of the amount of the special distribution for each
    participating McNeil Partnership.

   The condition to closing described in the second bullet point above has been
satisfied. On July 8, 1999, the court granted final approval to the settlement
of the Schofield litigation and dismissed the action.

   The obligations of WXI/McN Realty to effect the transaction also are subject
to the fulfillment or waiver by WXI/McN Realty of the following additional
conditions, among others:

  . Sellers having obtained the consent and estoppel certificate of each
    lender of mortgage debt which is being indirectly assumed by WXI/McN
    Realty;

                                       35
<PAGE>


  . title to each property owned by a participating McNeil Partnership being
    free and clear of all material encumbrances and property restrictions,
    other than permitted restrictions and encumbrances and other than matters
    which would not reasonably preclude the continued use of that property as
    it is being used as of the date of the Master Agreement or would not
    reasonably materially and adversely affect the value of that property as
    it is being used as of the date of the Master Agreement;

  . Lawyer's Title Insurance Corporation, or another nationally recognized
    title insurance company reasonably acceptable to Sellers and WXI/McN
    Realty, being unconditionally obligated and prepared to issue to or for
    the benefit of WXI/McN Realty and one or more of its subsidiaries either
    (a) an extended coverage ATLA owner's policy of title insurance (or the
    equivalent in the applicable jurisdiction) effective as of the closing
    date for each property owned by each participating McNeil Partnership or
    (b) at the option of WXI/McN Realty, a "date-down" to an existing policy
    of owner's title insurance, in each case in accordance with the title
    commitments given by Lawyer's Title Insurance Corporation to WXI/McN
    Realty, except for some permitted exclusions;

  . Sellers having received estoppels from tenants (including tenants leasing
    space pursuant to specified commercial leases) leasing at least 75% of
    the aggregate square footage leased pursuant to all commercial leases;

  . Sellers having received an estoppel from each lessor under a ground
    lease;

  . the sum of the net operating incomes, calculated as provided in the
    Master Agreement, for each participating McNeil Partnership for the
    twelve months ended on the last day of the most recently completed fiscal
    month prior to the closing date of the transaction being greater than or
    equal to the product determined by multiplying (a) 0.8723 by (b) an
    amount equal to the sum of the net operating incomes, calculated as
    provided in the Master Agreement, for each participating McNeil
    Partnership for its 1998 fiscal year; and

  . the contributions by McNeil Partners of its interests in the
    participating McNeil Partnerships, assets of McNeil Partners related to
    the McNeil Partnerships and certain assets of McREMI having been
    consummated.

Termination of the Master Agreement (page  )

   Right to terminate the Master Agreement in its entirety

   The Master Agreement provides that it may be terminated in its entirety, at
any time prior to the effective time of the mergers, regardless of whether or
not the requisite approvals of the holders of limited partner units in any of
the McNeil Partnerships have been obtained, as follows:

  . by the mutual written consent of each Seller and WXI/McN Realty;

  . by WXI/McN Realty or any Seller if any judgment or injunction has been
    issued preventing the consummation of the transaction other than with
    respect to any McNeil Partnership that is not a participating McNeil
    Partnership;

  . by WXI/McN Realty or any Seller if the closing has not occurred on or
    before June 24, 2000;

  . by any Seller if (a) WXI/McN Realty materially breaches any of its
    representations, warranties, covenants, obligations or agreements set
    forth in the Master Agreement, (b) that breach cannot be or is not
    remedied within 30 days and (c) the conditions to Sellers' obligations to
    close relating to the accuracy of WXI/McN Realty's representations and
    warranties and the performance of its obligations cannot be satisfied by
    June 24, 2000; or

  . by WXI/McN Realty if (a) any Seller material breaches any of its
    representations, warranties, covenants, obligations or agreements set
    forth in the Master Agreement, (b) that breach cannot be or is not
    remedied within 30 days and (c) the conditions to WXI/McN Realty's
    obligations to close relating to the accuracy of Sellers' representations
    and warranties and the performance of their obligations cannot be
    satisfied by June 24, 2000.

 Right to terminate the Master Agreement with respect to one or more McNeil
 Partnerships

   In addition to the right of WXI/McN Realty and Sellers to terminate the
Master Agreement in its entirety, under some circumstances, the Master
Agreement may be terminated with respect to a particular McNeil Partnership and
that McNeil Partnership will be excluded from the transaction, whether or not
the requisite approval of that McNeil Partnership has been obtained. These
circumstances include, among others:

  . by the mutual written consent of each Seller and WXI/McN Realty;

  . by WXI/McN Realty or any Seller if any judgment or injunction has been
    issued preventing the consummation of the transaction with respect to
    that McNeil Partnership;

  . by WXI/McN Realty or any Seller if the holders of the requisite number of
    limited partner units in that McNeil Partnership have not approved the
    merger proposal with respect to that McNeil Partnership;

  . by any Seller if prior to the approval of the merger proposal by the
    limited partners of that McNeil Partnership the general partner of that
    McNeil Partnership, in the exercise of its good faith judgment as to its
    fiduciary duties, determines that it is required to terminate the Master
    Agreement with respect to that McNeil Partnership because a superior
    acquisition proposal (as defined in "The Master Agreement--Material
    covenants--No solicitation by Sellers") has been made with respect to
    that McNeil Partnership;

  . by WXI/McN Realty if the general partner of that McNeil Partnership: (a)
    in connection with an acquisition proposal (as defined in "The Master
    Agreement--Material covenants--No solicitation by Sellers") by a third
    party for that McNeil Partnership has failed to recommend to the limited
    partners of that McNeil Partnership the approval of the merger proposal,
    (b) in connection with an acquisition proposal for that McNeil
    Partnership, has withdrawn or modified in a manner adverse to WXI/McN
    Realty its approval or recommendation that the limited partners of that
    McNeil Partnership approve the merger proposal or (c) has approved or
    recommended an acquisition proposal for that McNeil Partnership; or

  . by any Seller in respect of a McNeil Partnership which Sellers have
    decided to exclude from the transaction because that McNeil Partnership
    may fail to satisfy the conditions to closing set forth in the Master
    Agreement, if WXI/McN Realty has not elected to keep that McNeil
    Partnership in the transaction (see "The Master Agreement--Conditions to
    closing--Removal notices").

 Effect of termination

   If the Master Agreement is validly terminated, either in its entirety or
with respect to one or more McNeil Partnerships, the Master Agreement will
become null and void and of no further force or effect, either in its entirety
in the case of termination of the Master Agreement, or with respect to one or
more McNeil Partnerships in the case of termination of the Master Agreement
with respect to those McNeil Partnerships, and none of the parties to the
Master Agreement, or any of their respective subsidiaries, or any of their
respective partners, stockholders, members, equity holders, directors,
officers, employees, affiliates,agents, representatives, successors or assigns
will have any liability or obligation under the Master Agreement except that:

  . in the case of termination of the Master Agreement in its entirety, any
    obligations of the parties to the Master Agreement relating to the
    following will survive termination of the Master Agreement:
    confidentiality; fees and expenses; effect of termination; nonsurvival of
    representations, warranties and covenants; payment of break-up fee;
    reimbursement of expenses; and the provisions set forth in Article XI of
    the Master Agreement;

  . one or more of Sellers or WXI/McN Realty may have liability to one or
    more of Sellers or WXI/McN Realty if the basis of the termination is a
    willful, material breach by one or more of Sellers or WXI/McN Realty of
    one or more of the provisions of the Master Agreement; and

                                       37
<PAGE>


  .  in the case of termination of the Master Agreement in respect of a
     McNeil Partnership, the liabilities and obligations of the parties to
     the Master Agreement with respect to the other McNeil Partnerships would
     remain in effect, and any obligations of the parties to the Master
     Agreement relating to the following will survive termination of the
     Master Agreement in respect of that McNeil Partnership: confidentiality;
     correction and satisfaction of specified items relating to title;
     [additional disclosure for Fund XXV: the Harbour Club I purchase
     option]; public announcements; fees and expenses; binding effect of
     Stanger & Co. allocations; effect of termination; nonsurvival of
     representations, warranties and covenants; payment of break-up fee;
     reimbursement of expenses; and the provisions set forth in Article XI of
     the Master Agreement.


   In addition, in some circumstances if the Master Agreement is terminated,
WXI/McN Realty will receive a break-up fee and Sellers and WXI/McN Realty may
be required to reimburse some of the other's expenses incurred in connection
with the transaction.

Termination fees and expenses (page  )

   Except as described in "The Master Agreement--Fees and expenses," all costs
and expenses incurred in connection with the transaction will be paid by the
party incurring those costs and expenses.

   In addition, in some circumstances, WXI/McN Realty will receive a break-up
fee, calculated on a partnership by partnership basis, up to a maximum of $18.0
million, if the Master Agreement is terminated. These circumstances include,
among others:

  . the circumstances described in the fourth and fifth bullet points above
    in "--Right to terminate the Master Agreement with respect to one or more
    McNeil Partnerships;"

  . if:

    -- either (a) a person who is not an affiliate of WXI/McN Realty,
       WXI/McN Realty's managing member or Whitehall consummates an
       acquisition of more than 10% of the outstanding limited partner units
       in a McNeil Partnership following the date of the Master Agreement or
       (b) a person who is not an affiliate of WXI/McN Realty, WXI/McN
       Realty's managing member or Whitehall makes an acquisition proposal
       for a McNeil Partnership;

    -- that McNeil Partnership is excluded from the transaction because the
       holders of the requisite number of limited partner units in that
       McNeil Partnership have not approved the merger proposal with respect
       to that McNeil Partnership; and

    -- that McNeil Partnership enters into a definitive agreement relating
       to a higher acquisition proposal (as defined in "The Master
       Agreement--Fees and expenses--Partnership break-up fee") within six
       months of that McNeil Partnership being excluded from the
       transaction; or

  . the general partner of a McNeil Partnership as of the date of the Master
    Agreement is replaced and that McNeil Partnership is excluded from the
    transaction because the holders of the requisite number of limited
    partner units in that McNeil Partnership have not approved the merger
    proposal with respect to that McNeil Partnership.

   Each McNeil Partnership that is excluded from the transaction as described
in the immediately preceding bullet points will be severally liable for payment
to WXI/McN Realty of its partnership break-up fee as set forth in the table
under "The Master Agreement--Fees and expenses--Partnership break-up fee." The
break-up fee payable by each McNeil Partnership is calculated based on the
percentage set forth in the column "Partnership Percentage" in Table 2 opposite
the name of that McNeil Partnership. The break-up fee payable by the
Partnership in those circumstances is $    . No other party to the Master
Agreement will have any liability to WXI/McN Realty or to an excluded McNeil
Partnership for the partnership break-up fee of that excluded McNeil
Partnership.

<PAGE>


   In some circumstances where the Master Agreement is terminated by WXI/McN
Realty, Sellers may be required to reimburse WXI/McN Realty for the actual,
reasonable out-of-pocket expenses incurred by WXI/McN Realty in connection with
the transaction, up to an aggregate maximum amount of $1.5 million. In
addition, in some circumstances where the Master Agreement is terminated by
Sellers, WXI/McN Realty may be required to reimburse Sellers for the actual,
reasonable out-of-pocket expenses incurred by Sellers in connection with the
transaction, up to an aggregate of $1.5 million. Any receipt by WXI/McN Realty
of any one or more partnership break-up fees will offset any obligation of
Sellers to reimburse WXI/McN Realty for its expenses. See "The Master
Agreement--Fees and expenses--Reimbursement of expenses."

Financing; source of funds (page )

   The total amount of funds required by WXI/McN Realty in connection with the
consummation of the transactions (assuming all McNeil Partnerships are
participating McNeil Partnerships) is estimated to be approximately $      ,
including:

  . payment of the cash consideration to the limited partners of the McNeil
    Partnerships in the amount of approximately $         ;

  . repayment of debt of the McNeil Partnerships in the aggregate amount of
    approximately $       ;

  . payment of prepayment fees relating to mortgage debt of the McNeil
    Partnerships that will be repaid at closing and the payment of the
    assumption fees that WXI/McN Realty is required to pay pursuant to the
    Master Agreement in the aggregate amount of approximately $           ;

  . the amount of the shortfall, if any, of the amount of cash on hand held
    by each of the participating McNeil Partnerships at the time of the
    closing from the estimated amount of the special distribution that each
    participating McNeil Partnership is expected to make (as of the date of
    this Proxy Statement, the shortfall is estimated to be approximately
    $         ); and

  . all other expenses expected to be incurred in connection with the
    transaction and other amounts that WXI/McN Realty is required to pay
    pursuant to the Master Agreement in an aggregate amount estimated to be
    approximately $              .

   The amounts set forth above will vary if one or more of the McNeil
Partnerships are not participating McNeil Partnerships or if the amount of
working capital distributions, expenses or other amounts vary from the
estimated amounts included in calculating the amounts set forth above.

   It is expected that the amount of funds required by WXI/McN Realty in
connection with the transaction will be obtained through a combination of
equity and debt financing. Under the terms of the WXI/McN Realty Operating
Agreement, the managing member of WXI/McN Realty, which is owned by Whitehall
and Archon, has agreed to contribute to WXI/McN Realty an amount in cash equal
to the amounts described above, and pursuant to the terms of an equity
commitment letter from Whitehall to WXI/McN Realty, Whitehall has agreed to
provide, or to cause one or more of its affiliates to provide, a cash capital
contribution to WXI/McN Realty in an amount equal to the amounts described
above. The funds to be used by Whitehall to meet its funding commitments are
expected to come from capital contributions from the partners in Whitehall. It
is also expected that WXI/McN Realty will obtain third party mortgage or other
financing that will provide a portion of the amount of required funds described
above, although WXI/McN Realty has not, as of the date of this Proxy Statement,
entered into any agreements with respect to any third party mortgage or other
financing.

Accounting treatment of transaction (page )

   The transaction will be accounted for under the "purchase" method of
accounting in accordance with generally accepted accounting principles.


                                       39

Federal income tax consequences (page )

   Limited partners will recognize gain or loss on the conversion of their
limited partner units into cash in the merger [additional disclosure for Funds
XX-XXVI: or on receipt of cash pursuant to the exercise of dissenters' rights].
This gain or loss will be equal to the difference between the limited partner's
"amount realized" as a result of the merger and the limited partner's adjusted
tax basis in the limited partner units converted. The gain or loss will be
treated as capital gain or capital loss. However, a portion of that gain or
loss that is attributable to so-called "unrealized receivables" (which includes
recapture of some depreciation deductions previously taken) and "inventory
items" (as defined in Section 751 of the Internal Revenue Code) may be treated
as ordinary income or ordinary loss. In general, the special distribution of
cash will not be taxable and will be treated as a return of capital to the
limited partners. The return of capital to a limited partner will reduce that
limited partner's adjusted tax basis in its limited partner units in the
Partnership to the extent of that return of capital and, therefore, may
increase the amount of any gain or decrease the amount of any loss recognized
by that limited partner on the conversion of its limited partner units into
cash in the merger. To the extent that the special distribution received by a
limited partner exceeds that limited partner's adjusted tax basis in all of its
limited partner units, that excess will be taxable and will be treated as
capital gain. Limited partners should consult their respective tax advisors as
to the particular tax consequences of the transaction.

   The transaction, as structured, will allow McNeil Partners to make the
contributions of its interests in the McNeil Partnerships and the assets of
McNeil Partners and McREMI to WXI/McN Realty on a tax-free basis and to defer
substantial tax liability that would be incurred if the properties were
disposed of in a taxable sale. A taxable sale of the properties would produce
taxable gain in excess of the cash proceeds because of the relief of
partnership liabilities allocated to the McNeil Affiliates.

[For Funds XX-XXVI: Dissenters' rights (page )

   Under Article 7.6 of the California Corporations Code, a limited partner of
the Partnership who does not wish to accept the merger consideration may
dissent from the merger proposal and require the Partnership to purchase for
cash, at their fair market value, the limited partner units owned by that
limited partner if:

  . the Partnership participates in the transaction,

  . the limited partner does not vote for the merger proposal, and

  . the limited partner follows specific procedures set forth in the
    California Revised Limited Partnership Act.

Article 7.6 of the California Corporations Code is attached to this Proxy
Statement as Appendix E.]

                                SPECIAL FACTORS

Background of the transaction

   At a meeting held on June 24, 1999, the McNeil Investors board of directors
unanimously determined that the merger proposal is fair to and in the best
interests of the Partnership and its limited partners, approved the merger
proposal and determined to recommend that the limited partners of the
Partnership vote for the merger proposal. See "--Purposes and reasons for the
transaction," "--Effects of the transaction," "--Recommendations of the special
committee and the McNeil Investors board of directors; fairness of the
transaction" and "--Interests of certain persons in matters to be acted upon;
conflicts of interest." The determinations of the McNeil Investors board of
directors and its approval of the merger proposal were based on the
recommendation of the special committee and the fairness opinion delivered on
that date to the McNeil Investors board of directors by Stanger & Co. on behalf
of the McNeil Partnerships to the effect that each of the aggregate
consideration, the allocations of the aggregate consideration and the estimated
per unit aggregate amount to be received with respect to each class of limited
partners of each of the McNeil Partnerships is fair from a financial point of
view to the holders of each class of limited partner units in each of the
McNeil Partnerships. The following discussion sets forth information relating
to the background of the transaction.

 Organization of the public McNeil Partnerships

   The public McNeil Partnerships were formed in the 1970s and 1980s to engage
in the business of investing in, holding, managing and disposing of real estate
and real estate-related investments. The original principal objectives of the
public McNeil Partnerships were to provide capital appreciation and tax-
deferred income to their partners.

 Restructuring of the public McNeil Partnerships

   In 1991 and 1992, each of the public McNeil Partnerships was restructured.
In the restructuring, McNeil Partners became the sole new general partner of
each of the public McNeil Partnerships. See "--Interests of certain persons in
matters to be acted upon; conflicts of interest--Relationships among the McNeil
Affiliates and the McNeil Partnerships." In addition, the limited partnership
agreement of each of the public McNeil Partnerships was amended as part of the
restructuring. In each of the limited partnership agreements of the public
McNeil Partnerships, as amended, McNeil Partners agreed to commence a
liquidation of the properties of the McNeil Partnership seven years after the
restructuring date and to use commercially reasonable efforts to complete the
liquidation and termination of each of the public McNeil Partnerships by
December 31, 1999. Each of the limited partnership agreements provides that the
term of the McNeil Partnership will continue until a date beyond December 31,
1999 unless it is terminated earlier.

 Icahn tender offers

   In August 1995 and September 1996, High River Limited Partnership, a
Delaware limited partnership controlled by Carl C. Icahn ("High River"), made
unsolicited tender offers to purchase outstanding limited partner units in each
of Funds IX, X, XI, XIV, XV, XX, XXIV, XXV, XXVI and XXVII. Although McNeil
Partners contemplated making tender offers for some of the limited partner
units at a higher price than the High River tender offers, McNeil Partners did
not make any tender offers for the limited partner units in any of the public
McNeil Partnerships. [Additional disclosure for Funds IX-XI, XIV, XV, XX, XXIV-
XXVII: The beneficial ownership of limited partner units in the Partnership by
Mr. Icahn and his affiliates as of      , 1999 is set forth in "Related
Security Holder Matters--Principal holders of limited partner units."] The
statements filed by McNeil Partners with the SEC in response to the Icahn
tender offers stated that each of the McNeil Partnerships that was the subject
of an Icahn tender offer had determined to begin an orderly liquidation of all
of its assets. See "--Purposes and reasons for the transaction."

 Background of the Schofield litigation

   In August 1995, limited partners of some of the McNeil Partnerships filed
three separate purported class actions, derivative actions or both on behalf of
the limited partners of some of the McNeil Partnerships. Plaintiffs alleged
that McNeil Partners, McNeil Investors, McREMI and three of their senior
officers and/or directors breached their fiduciary duties and some of their
obligations under the respective limited partnership agreements of the McNeil
Partnerships. Plaintiffs alleged that defendants rendered limited partner units
in the McNeil Partnerships highly illiquid, and artificially depressed the
prices that were available for limited partner units in private sales.
Plaintiffs also alleged that defendants engaged in a course of conduct to
prevent the acquisition of limited partner units by High River by disseminating
purportedly false, misleading and inadequate information. Plaintiffs further
alleged that defendants acted to advance their own personal interests at the
expense of the public McNeil Partnerships' limited partners by failing to sell
the properties of the public McNeil Partnerships and failing to make
distributions to the limited partners.

   In late 1996, the parties agreed, and the court so ordered, that these
actions would be consolidated under the action, Schofield et al. v. McNeil
Partners, L.P. et al., Superior Court of the State of California for the County
of Los Angeles, Case No. BC133799 (Class and Derivative Action Complaint). On
December 16, 1996, plaintiffs filed a consolidated and amended complaint, suing
for breach of fiduciary duty, breach of contract and an accounting. Plaintiffs
alleged, among other things, that the management fees paid to McNeil Partners
over the last six years were excessive, that these fees should be reduced
retroactively and that the respective limited partnership agreements governing
the McNeil Partnerships were invalid.

   On February 14, 1997, defendants filed a demurrer to the consolidated and
amended complaint and a motion to strike, seeking to dismiss the consolidated
and amended complaint in all respects. The court granted defendants' demurrer
on May 5, 1997, dismissing the consolidated and amended complaint with leave to
amend. On October 31, 1997, plaintiffs filed a second consolidated and amended
complaint. Prior to the time defendants were required to move, answer or
otherwise respond, however, the case was stayed pending settlement discussions.
Because the transaction contemplated in the settlement included all of the
McNeil Partnerships and plaintiffs claimed that an effort should be made to
sell all of the McNeil Partnerships, in or around September 1998, plaintiffs
filed a third consolidated and amended complaint which included allegations
with respect to the McNeil Partnerships which had not been named in previously
filed complaints.

   On September 15, 1998, the parties signed a Stipulation of Settlement. For
purposes of settlement, the parties stipulated to a class comprised of all
owners of limited partner units in the McNeil Partnerships during the period
beginning June 21, 1991, the earliest date that proxy materials began to be
issued in connection with the restructuring of the McNeil Partnerships, through
September 15, 1998. As structured, the Stipulation of Settlement provided for
the payment of over $35 million in distributions and the commitment to market
the McNeil Partnerships for sale, together with McREMI, through a fair and
impartial bidding process overseen by a national investment banking firm. To
ensure the integrity of that process, defendants agreed, among other things, to
involve plaintiffs' counsel in oversight of that process, and plaintiffs'
counsel retained an independent advisor to represent the interests of limited
partners of the McNeil Partnerships in the event of a transaction. The
transaction described in this Proxy Statement is a result of that process. The
settlement was not conditioned on the consummation of the transaction described
in this Proxy Statement.

   On October 6, 1998, the court gave preliminary approval to the settlement.
It granted final approval to the settlement on July 8, 1999 and entered a Final
Order and Judgment dismissing the consolidated action with prejudice. As a
condition of final approval, the court requested, and the parties agreed to, a
slight modification of the release in the Stipulation of Settlement with
respect to future claims. Plaintiffs' counsel intends to seek an order awarding
attorneys' fees and reimbursing their out-of-pocket expenses in an amount which
is as yet undetermined.

 Background of the auction process

   To carry out the requirements of the limited partnership agreements of the
public McNeil Partnerships and the previously announced plans of liquidation
referred to in the context of the Icahn tender offers, in late 1997, executive
officers of McNeil Investors and McREMI (referred to in this Proxy Statement as
"McNeil management") began interviewing investment banks to explore
alternatives for maximizing value to the limited partners of each of the McNeil
Partnerships. In addition, pursuant to settlement of the Schofield litigation,
McNeil Partners and its affiliates committed to market the McNeil Partnerships
for sale, together with McREMI, through a fair and impartial bidding process
overseen by a national investment banking firm. See "--Purposes and reasons for
the transaction." The McNeil Affiliates retained Skadden, Arps, Slate, Meagher
& Flom LLP ("Skadden, Arps") as their legal advisor and on May 21, 1998
retained Houlihan, Lokey, Howard & Zukin Capital ("Houlihan, Lokey") as their
financial advisor.

  Engagement of PaineWebber

   On November 24, 1997, each of the McNeil Partnerships retained PaineWebber,
Incorporated ("PaineWebber") as its exclusive financial advisor based on
PaineWebber's experience in real estate transactions. PaineWebber was retained
to assist the McNeil Partnerships in connection with the investigation of
alternatives available to the McNeil Partnerships in furtherance of a
transaction which would maximize the value of each of the McNeil Partnerships.
PaineWebber was also retained to assist the McNeil Partnerships and McNeil
management in the marketing and sale of the McNeil Partnerships and the
outstanding interests in and assets of the McNeil Partnerships. PaineWebber was
not retained by the McNeil Partnerships to provide tax, accounting or legal
advice, to provide an appraisal of any of the assets of the McNeil
Partnerships, to provide any advice in respect of the Schofield litigation or
to provide any fairness opinions or to render any advice to any party other
than the McNeil Partnerships and the McNeil General Partners, as general
partners of the McNeil Partnerships.

   Pursuant to the terms of its engagement letter with PaineWebber, the McNeil
Partnerships agreed to pay PaineWebber a retention fee and a transaction fee.
The aggregate retention fee for all of the McNeil Partnerships is $50,000 per
month and is payable each month during the term of PaineWebber's engagement.
The transaction fee is payable only upon consummation of the transaction. The
transaction fee is equal to 0.57% of the aggregate consideration paid for the
McNeil Partnerships, McREMI, McNeil Investors and McNeil Partners. The
transaction fee is currently estimated to be approximately $       (assuming
all McNeil Partnerships participate in the transaction). The transaction fee is
payable at the closing of the transaction and will be reduced by previously
paid retention fees. In addition, the McNeil Partnerships have agreed to
reimburse PaineWebber for all reasonable out-of-pocket expenses incurred by it
in connection with its engagement, including reasonable fees and disbursements
of its legal counsel. The McNeil Partnerships have also agreed to indemnify
PaineWebber against certain liabilities in connection with its engagement,
including certain liabilities under the federal securities laws.

  Structuring of the transaction

   At the commencement of its engagement, PaineWebber advised McNeil Partners
that the highest price for the McNeil Partnerships and, therefore, the greatest
distribution to the limited partners of each of the McNeil Partnerships, would
likely be achieved by offering the McNeil Partnerships and McREMI together on
an all-or-none basis. See "--Purposes and reasons for the transaction."
PaineWebber perceived the advantages of an all-or-none transaction as compared
to separate asset sales of individual McNeil Partnerships to include, among
others, relatively quick liquidity, a less time-consuming marketing period and
the likelihood of a higher aggregate purchase price.

   In addition, at the commencement of its engagement, PaineWebber advised
McNeil Partners that potential purchasers of large real estate portfolios were
continuing to raise capital in the debt and equity markets and that some of the
potential purchasers would likely pay a premium to acquire large portfolios of
assets, rather than acquire individual assets on a piecemeal basis. This factor
made a sale of the underlying properties, rather than

                                       43
<PAGE>

the McNeil Partnerships, equally unsatisfactory to McNeil Partners. Among other
factors, McNeil Partners itself preferred an all-or-none transaction because it
felt that the uneven performance of the various properties owned by the McNeil
Partnerships might allow prospective purchasers to "cherry-pick" the most
desirable assets to the exclusion of the others. In particular, PaineWebber
believed that because of the age, product mix
and geographic diversity of the McNeil Partnerships' property portfolio, the
marketing process would likely benefit from McREMI's on-going relationship with
the assets because of McREMI's track record in managing the properties and its
intimate familiarity with the operations and physical condition of those
properties which could not be easily replicated in the short-term. In addition,
PaineWebber advised McNeil management that commencing during the final months
of 1997, there was a significant industry-wide shortage of asset and property
management personnel.

   PaineWebber's advice to market the McNeil Partnerships and McREMI together
in a single portfolio was consistent with the advice received by McNeil
Partners from other investment banks interviewed in late 1997.

   On the basis of PaineWebber's advice, McNeil management decided (1) to
market the McNeil Partnerships, McNeil Investors, McNeil Partners and McREMI as
a single portfolio (referred in this Proxy Statement as the "McNeil
portfolio"), and (2) to instruct prospective purchasers to be instructed to
submit bids only for the entire McNeil portfolio. See "--Purposes and reasons
for the transaction."

   During December 1997 and January 1998, PaineWebber performed due diligence
on the McNeil Partnerships and worked with the McNeil Affiliates and McNeil
management to prepare offering materials based upon the McNeil Partnerships'
books and records. The offering materials consisted of (1) a confidential
offering memorandum, which outlined the offering process and timing, identified
the McNeil Affiliates and the McNeil Partnerships and summarized property
operations, historical and projected capital expenditures and existing debt,
and (2) a property information book, which provided portfolio and property
level detail, including individual property photographs and maps. Subsequent to
the distribution of the offering materials, a bid form was distributed to each
potential purchaser. This bid form outlined the bid process and set forth the
specifics of the proposed transaction and the requirements for a conforming
bid. The bid form and its attachments provided, among other things, that:

  . one offer should be submitted, at one price, on an all-or-none basis, for
    the McNeil Partnerships, McREMI, McNeil Investors and McNeil Partners;

  . the McNeil Partnerships would be acquired by merger;

  . the McNeil Partnerships were seeking only cash offers for the limited
    partner interests in the McNeil Partnerships (see "--Purposes and reasons
    for the transaction");

  . offers to acquire the general partner interests in the McNeil
    Partnerships and the ownership interests in McREMI, McNeil Investors and
    McNeil Partners could include cash, operating partnership units or a
    combination of cash and operating partnership units;

  . the McNeil Partnerships were seeking offers for all of the McNeil
    Partnerships, McREMI, McNeil Investors and McNeil Partners; and

  . offers for ownership interests in less than all of the McNeil
    Partnerships, McREMI, McNeil Investors and McNeil Partners would not be
    considered.

   At the time the bid form was distributed, McNeil Partners acknowledged that
any transaction would be subject to conditions, including approval of the
limited partners of each of the McNeil Partnerships, settlement of the
Schofield litigation described above in "--Background of the transaction--
Background of the Schofield litigation" and receipt of an opinion from Stanger
& Co. as to the fairness of the consideration received by each of the McNeil
Partnerships in any such transaction.

                                       44
<PAGE>

  Engagement of Stanger & Co. to provide fairness opinions

   On January 12, 1998, each of the McNeil Partnerships retained Stanger & Co.
as its independent advisor to render certain opinions as to the fairness from a
financial point of view to the limited partners of each of the McNeil
Partnerships of the consideration to be received by each of the McNeil
Partnerships pursuant to a transaction.

  Solicitation of initial bids

   On January 30, 1998, after reviewing more than 240 potential bidders,
PaineWebber, in consultation with McNeil management, prepared a refined list of
eighteen potential purchasers. The eighteen potential purchasers were
identified based on (1) their financial ability to acquire a large portfolio of
real estate assets with limited financing contingencies and (2) their
experience and track record in closing large real estate portfolio
transactions. One of these eighteen potential purchasers was an affiliate of
Whitehall.

   PaineWebber contacted each of the eighteen potential purchasers and verbally
solicited interest in the proposed transaction. PaineWebber received verbal
indications of interest from all of the eighteen potential purchasers.
Beginning on February 3, 1998, a form of confidentiality agreement was
delivered to each of the eighteen potential purchasers which had not previously
signed the form of confidentiality agreement. Because of the confidential
nature of the information disclosed in the offering materials, each of the
eighteen potential purchasers was required to sign the form of confidentiality
agreement prior to receiving the offering materials. Of the eighteen potential
purchasers, two materially amended the form of confidentiality agreement and
therefore were excluded from the bidding process based on advice from legal
counsel to the McNeil Partnerships, one potential purchaser was excluded from
the bidding process due to a potential conflict of interest, two potential
purchasers did not sign the form of confidentiality agreement and two potential
purchasers were excluded from the process pursuant to instructions from McNeil
Partners. As a result, of the eighteen potential purchasers identified by
PaineWebber, the eleven potential purchasers who signed the form of
confidentiality agreement received offering materials. The offering materials
were distributed by PaineWebber beginning on February 4, 1998.

   The auction process included two rounds of bids. The initial due diligence
period extended from February 5 to March 19, 1998, during which time the eleven
prospective purchasers who received the offering materials performed due
diligence. A data room was established in Dallas, Texas, where due diligence
files and other contracts and financial information were made available. In
addition, senior members of McNeil management were available during this due
diligence period to answer questions from the potential purchasers. Potential
purchasers also had the opportunity to tour individual properties by performing
"drive-by" inspections.

   In addition, to facilitate the bidding and due diligence processes and in an
effort to limit potential contingencies in the bids, the McNeil Partnerships
engaged Professional Services Industries, Inc. ("PSI") to perform Phase I
environmental testing on the properties and Phase II environmental testing on
one property. All reports from PSI were available for review by potential
purchasers throughout the offering process.

   During the initial due diligence period, two additional potential purchasers
expressed an interest in the transaction for the McNeil portfolio. Each of
these potential purchasers received and signed the form of confidentiality
agreement without significant amendment and, therefore, received the offering
materials.

   Initial bids from the thirteen prospective purchasers were due no later than
3:00 p.m., Pacific time, on March 20, 1998. Eight prospective purchasers,
including the Whitehall affiliate, submitted initial bids by the March 20
deadline. The bids ranged from $600.0 million to $750.7 million, with varying
levels of contingencies and numerous financing sources. Pursuant to the bid
form, each of the bids received was to include a cash amount of $36.2 million,
representing the aggregate cash balance for all of the McNeil Partnerships as
of December 31, 1997.

                                       45
<PAGE>

  Solicitation of final bids

   From March 21, 1998 to April 8, 1998, PaineWebber contacted the remaining
eight bidders to discuss the financing sources and contingencies outlined in
the initial bids. Additionally, PaineWebber contacted each of the eight bidders
to confirm whether or not the bids submitted conformed to the procedures
outlined in the offering materials. On March 25, 1998, pursuant to instructions
from McNeil Partners, PaineWebber informed one of the bidders that McNeil
management had concerns regarding the ability of that bidder's joint venture
partner to close a transaction. As a result, on or about March 31, 1998, this
bidder replaced its joint venture partner with a new joint venture partner.
PaineWebber gave this bidder and each of the other bidders the opportunity to
submit revised bids by April 9, 1998.

   By April 9, 1998, five of the eight bidders, including the Whitehall
affiliate, had submitted revised bids. The five revised bids ranged from $681.1
million to $741.5 million, including the McNeil Partnerships' aggregate cash
balance of $36.2 million as of December 31, 1997. On May 12, 1998, a sixth
bidder submitted a revised bid of $645.0 million, including the McNeil
Partnerships' aggregate cash balance of $36.2 million as of December 31, 1997.

   PaineWebber and McNeil management reviewed the March 20 initial bids and the
revised bids, and McNeil management, in consultation with PaineWebber, selected
the three highest bidders. The Whitehall affiliate was not one of the three
final bidders. This selection was based on the highest total dollars offered in
the bids, the extent of contingencies contained in the bids, PaineWebber's and
McNeil management's assessment as to the ability of the bidders to secure
adequate financing for the transaction and to close the transaction and
subsequent discussions among McNeil management, PaineWebber and the bidders.
The bids submitted by the three highest bidders (taking into account the
revised bids and the original bids of the three bidders which did not submit
revised bids) totaled $750.7 million, $741.5 million and $738.7 million,
respectively, including the McNeil Partnerships' aggregate cash balance of
$36.2 million as of December 31, 1997.

   From April 13, 1998 to May 29, 1998, a final due diligence period was
established. McNeil management established this additional due diligence period
to allow each of the final bidders every opportunity to complete its due
diligence and submit its highest and best bid. In addition, some of the final
bidders had requested additional time to complete their due diligence.

   On April 14, 1998, PaineWebber provided the three final bidders with a
schedule summarizing significant operating and other material events that had
occurred with respect to each McNeil Partnership subsequent to the original
printing and distribution of the offering materials in early February 1998.

   On April 24, 1998, PaineWebber distributed to the three final bidders an
overview of the final bid process which informed the three final bidders that
during the final due diligence period PaineWebber and McNeil management would
schedule, at the request of the three final bidders, times for these bidders to
visit the due diligence data room in Dallas, to conduct "walk through" property
inspection tours and to interview both corporate and property-level management
of the McNeil Partnerships and the properties. Also during the due diligence
period, PaineWebber and McNeil management continued to review the McNeil
portfolio and to address outstanding environmental, structural, title and
operational issues. To facilitate the final bidding and due diligence processes
and in an effort to limit potential contingencies in the final bids, PSI, at
the request of the McNeil Partnerships, prepared structural and engineering
reports for the properties, and American Title Insurance Company ("American
Title") was retained to prepare preliminary title reports and commitments. All
reports from PSI and American Title were delivered to the McNeil Partnerships
from May 14, 1998 to May 18, 1998 and were immediately available for review by
the three final bidders.

   In addition, on May 22, 1998, PaineWebber provided the three final bidders
with a first quarter unaudited balance sheet for each McNeil Partnership and a
schedule summarizing significant events that had occurred with respect to each
McNeil Partnership subsequent to the original printing and distribution of the
offering

                                       46
<PAGE>

materials and subsequent to the April 14 schedule. The May 22 schedule informed
the three final bidders that: from March 31, 1998 to April 30, 1998, the McNeil
Partnerships had sold six assets for total consideration of approximately $40.1
million; an outstanding note receivable secured by a mortgage on an
unaffiliated property had been paid-off, with the respective McNeil
Partnership's portion being $1,992,000; and one property, which secured a
mortgage with an aggregate balance of $5,957,419, had been foreclosed upon.

   On May 27, 1998, PaineWebber provided each of the three final bidders with a
final bid package. The final bid package included a form letter of intent and a
summary schedule of all properties and mortgage loans of each McNeil
Partnership as of March 31, 1998. The form letter of intent served as the final
bid form and indicated the final bidder's intent to negotiate a definitive
acquisition agreement consistent with the terms set forth in the form of
acquisition agreement included in the final bid package. The final bids were
required to conform to the same requirements as the initial bids, including,
among other things, that:

  . one offer should be submitted, at one price, on an all-or-none basis, for
    the McNeil Partnerships, McREMI, McNeil Investors and McNeil Partners;

  . the McNeil Partnerships would be acquired by merger;

  . the McNeil Partnerships were seeking only cash offers for the limited
    partner interests in the McNeil Partnerships (see "--Purposes and reasons
    for the transaction");

  . offers to acquire the general partner interests in the McNeil
    Partnerships and the ownership interests in McREMI, McNeil Investors and
    McNeil Partners could include cash, operating partnership units or a
    combination of cash and operating partnership units;

  . the McNeil Partnerships were seeking offers for all of the McNeil
    Partnerships, McREMI, McNeil Investors and McNeil Partners; and

  . offers for ownership interests in less than all of the McNeil
    Partnerships, McREMI, McNeil Investors and McNeil Partners would not be
    considered.

   In addition, the final bids were required to include a cash amount of
approximately $42.0 million, representing the aggregate cash balance for all of
the McNeil Partnerships as of April 30, 1998, adjusted for asset sales,
foreclosures and pay-offs of mortgage debt subsequent to March 31, 1998. Each
final bidder was required to outline the proposed structure for its acquisition
of the McNeil portfolio and to list any contingencies to its bid. With the
exception of those listed contingencies, by executing and returning the form
letter of intent, the final bidder waived all other conditions to signing the
acquisition agreement and represented that it had completed its inspections of
the properties and the other assets to be included in the transaction and had
satisfied itself as to the condition of the properties and the other assets.

   Final bids were due from the three final bidders no later than 3:00 p.m.,
Pacific time, on May 29, 1998. Two of the three final bidders submitted a bid.
The third final bidder ("Final Bidder 3") delivered a letter of interest to
McNeil management stating that it had received the final bid package on May 27
but was unable to submit a final bid by the May 29 deadline due to insufficient
time to review the bid package and related documents. However, Final Bidder 3
expressed a continued interest in a transaction for the McNeil portfolio.

   PaineWebber and McNeil management reviewed the two final bids received, and
McNeil Partners, after consultation with and considering the advice of
PaineWebber, selected the winning final bid. The selection of the winning final
bidder was based on the amount of the bids, the extent of contingencies
contained in the bids, and PaineWebber's and McNeil management's assessment of
the ability of the bidders to secure adequate financing for the transaction and
the ability of the bidders to close the transaction.

   The winning bidder ("Final Bidder 1") submitted a final bid of approximately
$727.4 million, including the McNeil Partnerships' aggregate cash balance of
approximately $42.0 million as of April 30, 1998, adjusted for asset sales,
foreclosures and pay-offs of mortgage debt subsequent to March 31, 1998. Final
Bidder 1's final bid also included $20.0 million to be deposited into escrow at
the closing of the transaction by Final Bidder 1

                                       47
<PAGE>

to fund scheduled deferred maintenance, capital expenditures and undisclosed
liabilities, as determined in Final Bidder 1's sole discretion. Final Bidder 1
indicated a high likelihood that the entire $20.0 million would be spent. Final
Bidder 1's final bid also was contingent upon negotiation and execution of a
definitive acquisition agreement to provide for customary allocation of closing
costs and was subject to closing conditions and prorations. Net of the escrow
amount and the cash balance, Final Bidder 1's final bid was approximately
$665.4 million.

   The second final bidder ("Final Bidder 2") submitted a final bid of
approximately $709.2 million, including the McNeil Partnerships' aggregate cash
balance of approximately $42.0 million as of April 30, 1998, adjusted for asset
sales, foreclosures and pay-offs of mortgage debt subsequent to March 31, 1998.
Net of the cash balance, Final Bidder 2's final bid was approximately $667.2
million. Final Bidder 2's bid was subject to the negotiation and execution of a
definitive acquisition agreement and a thirty-day period to review engineering,
title and survey reports; to conduct Phase II environmental testing on certain
properties; and to complete physical inspection of selected multifamily
properties.

  Negotiations with the final bidders

   McNeil management, PaineWebber, Skadden, Arps, Final Bidder 1 and Final
Bidder 1's advisors immediately commenced negotiating a definitive acquisition
agreement for the McNeil portfolio. Negotiations continued throughout the month
of June 1998. In early July 1998, during the course of these negotiations,
Final Bidder 1 informed McNeil management and its advisors that it was reducing
its proposed purchase price for the McNeil portfolio by $82.0 million. As a
result, Final Bidder 1's revised bid, net of the $20.0 million escrow amount
and the approximately $42.0 million cash balance, was reduced to approximately
$583.4 million. Final Bidder 1 did not provide an explanation for the reduction
in the proposed purchase price. However, McNeil management and PaineWebber
subsequently learned that beginning during the month of May 1998 and continuing
throughout the months of June and July 1998, Final Bidder 1 had been offering
for sale, but was having difficulty in selling, a similar portfolio of
properties that it owned at that time. In addition, during the months of May,
June and July 1998, the real estate market had begun to show signs of weakening
and there was increased volatility in the capital markets.

   After consultation with PaineWebber, McNeil management decided to cease
negotiations with Final Bidder 1 and instructed PaineWebber to contact Final
Bidder 2. However, Final Bidder 2 declined to pursue the transaction further,
due to internal issues and volatility in the capital markets.

   McNeil Partners then instructed PaineWebber to contact Final Bidder 3. On
July 26, 1998, Final Bidder 3 was provided with a draft of an acquisition
agreement for the McNeil portfolio. Following discussions among McNeil
management, PaineWebber and the management of Final Bidder 3, on July 28, 1998,
McNeil Partners and Final Bidder 3 entered into a letter agreement, expiring on
August 14, 1998, pursuant to which McNeil Partners agreed to negotiate the
terms of a definitive acquisition agreement with Final Bidder 3 on an
"exclusive basis." During the exclusivity period, McNeil management,
PaineWebber and Skadden, Arps continued to conduct discussions with Final
Bidder 3 and its legal and financial advisors with respect to the terms of a
transaction for the McNeil portfolio, including the structure of the
transaction and the aggregate purchase price.

   On August 14, 1998, Final Bidder 3's exclusivity period expired. McNeil
management and PaineWebber met with the management of Final Bidder 3. At that
time, McNeil management and the management of Final Bidder 3 agreed upon an
aggregate purchase price for the McNeil portfolio of approximately $692.4
million, including the McNeil Partnerships' April 30, 1998 aggregate cash
balance of approximately $42.0 million. Net of the cash balance, the agreed
upon purchase price for the McNeil portfolio, net of the cash balance, was
approximately $650.4 million. Final Bidder 3's proposed purchase price for the
McNeil portfolio, net of the cash balance, was later reduced to approximately
$648.1 million to reflect the repayment of a mortgage note receivable.

   The structure of the transaction proposed by Final Bidder 3 contemplated
that an off-balance sheet entity to be formed by a joint venture between Final
Bidder 3 and a to-be-determined source of equity financing would acquire the
McNeil portfolio. In addition, the transaction proposed by Final Bidder 3
required Final Bidder 3 to receive debt financing secured by some of the
properties. Negotiations between McNeil management and Final Bidder 3 continued
after August 14, 1998. However, the exclusivity period was not formally
extended.

  Solicitation of additional bids; continued discussions with Final Bidder 3

   During the period following the expiration of Final Bidder 3's formal
exclusivity period, at McNeil management's request, PaineWebber began
contacting additional potential purchasers who might be interested in bidding
or rebidding on the McNeil portfolio. However, there was little interest at or
near Final Bidder 3's price level because beginning in August 1998 and
continuing through this time, the debt capital markets had begun to
deteriorate. Consequently, in general, lending sources became more scarce and
capital that was available for potential purchasers was available on less
favorable terms. These factors restricted potential purchasers from
competitively pricing revised bids. As a result, from August 1998 until the
first quarter of 1999, many of the formerly aggressive buyers in the real
estate industry, including several of the original bidders and other potential
purchasers of the McNeil portfolio formerly identified by PaineWebber, had
begun disposing of their real estate assets, or reducing the priority of new
acquisitions, and many of the former lenders in the industry had effectively
exited the business of providing debt financing.

   Because of the unsettled condition of the real estate and capital markets
prevailing at the time, the difficulty of receiving a bid from a potential
purchaser that was higher than Final Bidder 3's bid at the time, and in
recognition of the progress made in the negotiations with Final Bidder 3,
McNeil management continued its negotiations with Final Bidder 3 during the
period that PaineWebber was contacting additional potential purchasers.

  During this period, Final Bidder 3 visited and inspected each property and
performed significant due diligence. McNeil management and PaineWebber
responded to various due diligence issues raised by Final Bidder 3 and its
advisors. Among other things, McNeil management addressed and remediated, as
requested by Final Bidder 3, several environmental issues disclosed in the
environmental reports prepared by PSI. At the request of McNeil management, PSI
performed Phase II environmental testing on eight properties and Phase III
environmental testing on two properties, and American Title updated the
preliminary title reports and commitments on the properties. All third party
reports were immediately available for review by Final Bidder 3 and its
advisors as soon as the reports were delivered to McNeil management.

   On October 19, 1998, PaineWebber, at McNeil management's request, met with
management of one of the original eight bidders to review the bidder's original
bid and to solicit interest in submitting a revised bid. PaineWebber provided
this bidder with the most recent due diligence information on the McNeil
portfolio, including all available third-party reports from PSI and American
Title. On October 22, 1998, this bidder submitted a revised verbal all-or-none
bid for the McNeil portfolio in the amount of $570.0 million, net of the McNeil
Partnerships' aggregate cash balance.

   On November 5, 1998, PaineWebber, at McNeil management's request, met with
management of a potential purchaser who was not an original bidder in the
auction. This potential purchaser executed the form of confidentiality
agreement signed by the other bidders and began a review of the offering
materials and the most recent due diligence information on the McNeil
portfolio, including all available third-party reports from PSI and American
Title. On November 9, 1999, this potential purchaser submitted a verbal all-or-
none bid for the McNeil portfolio in the amount of $575.0 million, net of the
McNeil Partnerships' aggregate cash balance.

   On November 16, 1998, after further negotiations and based on property-level
due diligence, Final Bidder 3 decreased its proposed purchase price for the
McNeil portfolio to approximately $646.1 million, net of the McNeil
Partnerships' aggregate cash balance.


                                       49
<PAGE>

   On or about December 1, 1998, PaineWebber, at McNeil management's request,
met with management of another of the original eight bidders to review the
bidder's original bid and to solicit interest in submitting a revised bid.
After this bidder signed the form of confidentiality agreement to extend its
confidentiality obligations, PaineWebber provided this bidder with the most
recent due diligence information on the McNeil portfolio, including all
available third-party reports from PSI and American Title. On December 21,
1998, this bidder submitted a revised verbal all-or-none bid for the McNeil
portfolio in the amount of $565.0 million, net of the McNeil Partnerships'
aggregate cash balance.

   The McNeil General Partners and their advisors considered the three verbal
bids; however, based on the amount of the bids, McNeil management did not
believe that these bids were fair to, or in the best interests of, the limited
partners of the McNeil Partnerships.

   On December 3, 1998, Final Bidder 3 sent a letter to McNeil management
outlining the final issues for discussion in the transaction documents for the
McNeil portfolio and stating that it would be prepared to sign definitive
agreements on February 2, 1999.

   On December 30, 1998, McNeil Partners received a proposal from Everest
Properties II, L.L.C. ("Everest"), a limited partner of some of the McNeil
Partnerships, to purchase for $35.0 million in cash the eight self-storage
properties owned by Fund XXVII. The Everest proposal included a fee of 3% of
the purchase price to be paid to a broker affiliated with Everest and an
exclusivity provision that would have prevented the McNeil Affiliates and the
McNeil Partnerships from negotiating with other bidders, including Final Bidder
3. In addition, the Everest proposal failed to take into account the fact that
the sale of the self-storage properties of Fund XXVII would require the
approval of the limited partners of Fund XXVII. The Everest proposal requested
a response by January 8, 1999.

   Throughout the month of January 1999, McNeil management, PaineWebber,
Skadden, Arps, Final Bidder 3 and Final Bidder 3's legal and financial advisors
continued to negotiate the terms of an acquisition agreement and related
transaction documents. During this period, however, Final Bidder 3 expressed
concern over its lack of equity or debt financing and the uncertainty of
available financing given the unsettled condition of the capital markets
prevailing at the time and the length of time which would likely transpire
before the closing of the transaction for the McNeil portfolio.

   On or about January 6, 1999, at McNeil management's request, PaineWebber met
with Final Bidder 2. Final Bidder 2 had expressed a renewed interest in a
transaction for the McNeil portfolio and in potentially rebidding on the McNeil
portfolio. Final Bidder 2 informed PaineWebber that it had severed its
relationship with the source of financing indicated in its May 29, 1998 final
bid and had obtained a new source of financing. After Final Bidder 2's new
source of financing executed the form of confidentiality agreement signed by
the other bidders, PaineWebber provided Final Bidder 2 and its financing source
with the most recent due diligence information for the McNeil portfolio,
including all available third-party reports of PSI and American Title.

   On January 7, 1999, the McNeil Investors board of directors held a special
meeting to discuss the status of discussions with Final Bidder 3 and the other
prospective purchasers and to discuss how to respond to the proposal received
from Everest. McNeil management and PaineWebber advised the McNeil Investors
board of directors that discussions were advancing between PaineWebber and
Final Bidder 3 with respect to the issues raised in Final Bidder 3's December
3, 1998 letter and that Final Bidder 3 would be meeting with potential equity
financing sources on January 8, 1999.

   PaineWebber then reviewed for the McNeil Investors board of directors the
status of discussions with the original bidder who had submitted a revised,
verbal bid on December 21, 1998 and with Final Bidder 2. PaineWebber indicated
that negotiations were continuing with Final Bidder 3 as well as Final Bidder 2
and believed that Final Bidder 2 would submit another bid for the McNeil
portfolio in the next several weeks. In addition, PaineWebber stated that it
believed that the open business issues with Final Bidder 3 could likely be
resolved within a relatively short period of time.

                                       50
<PAGE>

   The McNeil Investors board of directors then considered how to respond to
the proposal received from Everest. Skadden, Arps again advised the McNeil
Investors board of its duties in connection with the transaction and with
respect to the limited partners of the McNeil Partnerships. After extensive
discussion and in recognition of the progress of discussions with Final Bidder
3 and Final Bidder 2, the McNeil Investors board of directors decided to send a
letter of response to the Everest proposal, but not to make a definitive
decision with respect to the Everest proposal until bids were received from the
other interested parties it had directed PaineWebber to contact, at which time
the terms of the Everest proposal could be evaluated along with these other
bids.

   Also in early January 1999, McNeil management received a letter from High
River expressing an interest in bidding on the McNeil portfolio.

   On January 12, 1999, Final Bidder 2 submitted a verbal all-or-none bid for
the McNeil portfolio in the amount of $635.0 million in cash. However, Final
Bidder 2 also requested that the McNeil Partnerships pay for the cost of a
twelve month interest rate hedge to protect Final Bidder 2 against interest
rate volatility during the period from the signing of a definitive acquisition
agreement until the closing of the transaction for the McNeil portfolio. The
estimated cost of the hedge was $12.0 million. Final Bidder 2's bid, net of the
estimated cost of the hedge, was approximately $623.0 million. In addition, one
of the principals of Final Bidder 2's new financing source died on January 23,
1999. After discussions with PaineWebber, McNeil management was of the view
that the death of the principal called into question the ability of the
financing source to close a transaction for the McNeil portfolio on a timely
basis.

   On January 13, 1999, the McNeil Investors board of directors held a special
meeting to discuss the progress of discussions with Final Bidder 3, the bid
submitted by Final Bidder 2 and inquiries received from Everest and High River.
PaineWebber reviewed for the McNeil Investors board of directors the status of
negotiations with Final Bidder 2 and Final Bidder 3, and Skadden, Arps updated
the McNeil Investors board of directors on recent inquiries received from High
River and Everest with respect to the McNeil Partnerships. After discussion,
the McNeil Investors board of directors decided to proceed simultaneously with
Final Bidder 3 and Final Bidder 2, and to send to each of High River and
Everest for signature the form of confidentiality agreement signed by the other
bidders in the auction.

   On or about January 25, 1999, McNeil management and Final Bidder 3
tentatively agreed to an additional reduction of approximately $2.4 million in
Final Bidder 3's proposed purchase price for the McNeil portfolio for certain
environmental issues that Final Bidder 3 believed existed at certain properties
at that time. As a result, the purchase price offered by Final Bidder 3 was
reduced to approximately $643.7 million, net of the McNeil Partnerships'
aggregate cash balance.

   On January 26, 1999, the form of confidentiality agreement signed by the
other proposed purchasers and bidders in the auction was sent to High River for
signature. On February 4, 1999, counsel to High River responded that the terms
of the form of confidentiality agreement were unacceptable and therefore High
River would not sign the form of confidentiality agreement. The form of
confidentiality agreement signed by the other proposed purchasers and bidders
also was subsequently sent to Everest for its signature. Everest returned the
confidentiality agreement unsigned and with material amendments, which McNeil
Partners, in consultation with its legal advisors, considered unacceptable.

   On February 4, 1999, Final Bidder 3 received preliminary approval from its
board of directors to proceed with the transaction for the McNeil portfolio
subject to receipt of equity and debt financing commitments. However, final
approval from Final Bidder 3's board of directors would be needed to permit
Final Bidder 3 to enter into definitive agreements for the transaction for the
McNeil portfolio. On February 5, 1999, in an effort to give Final Bidder 3 an
incentive to incur costs necessary to allow its financing sources to begin due
diligence, McNeil Partners entered into a new exclusivity agreement with Final
Bidder 3. The exclusivity agreement provided for an expiration date of February
9, 1999. At the time of entering into the new exclusivity agreement, Final
Bidder 3 was informed that McNeil management and PaineWebber expected to meet
with

                                       51
<PAGE>

Final Bidder 3's financing sources and that these financing sources should
begin their financial due diligence on the McNeil portfolio prior to the end of
the exclusivity period.

   During the exclusivity period, Final Bidder 3 informed McNeil management of
the identity of all of its potential debt and equity financing sources. One of
the equity financing sources identified by Final Bidder 3 was an affiliate of
Whitehall. On February 9, 1999, McNeil management and PaineWebber met with
Final Bidder 3 and representatives of Whitehall to determine the level of
commitment of Final Bidder 3's equity financing sources. On that date, Final
Bidder 3 committed to enter into a letter of intent to obtain from an affiliate
of Whitehall the equity financing. Final Bidder 3 also committed to pay a good
faith deposit to Whitehall or its affiliates. The good faith deposit was a
prerequisite for Whitehall to begin its due diligence. As of the expiration of
the agreed-upon exclusivity period, however, none of Final Bidder 3's equity or
debt financing sources had begun financial due diligence on the McNeil
portfolio, and Final Bidder 3 had not paid a good faith deposit.

   From February 9, 1999 to February 22, 1999, Final Bidder 3 and McNeil
management continued to negotiate transaction documents. However, during this
time, Final Bidder 3 advised McNeil management and PaineWebber that its
prospective lending sources were very limited and that the lending sources
identified to McNeil management and PaineWebber would require a minimum due
diligence period of [60] days. In addition, Final Bidder 3 represented that its
debt financing sources would not allow a funding commitment to remain
outstanding for more than 90 days without an initial commitment fee of
approximately $1.0 million. Final Bidder 3 proposed that the McNeil
Partnerships pay this initial commitment fee.

   During the first three weeks of February 1999, representatives of Whitehall,
representatives of Final Bidder 3 and their respective advisors discussed the
terms of an equity investment by Whitehall or its affiliates or designees in
the Final Bidder 3 acquisition entity. During this period, Whitehall and Final
Bidder 3 began negotiating a term sheet outlining the preliminary terms of the
proposed investment by Whitehall or its affiliates. Final Bidder 3 provided
copies of this term sheet to McNeil management. The term sheet proposed that
Whitehall or its affiliates would provide the equity financing to the Final
Bidder 3 acquisition entity by means of a special purpose acquisition entity to
be jointly owned by an affiliate of Final Bidder 3 and an affiliate of
Whitehall.

   On February 22, 1999, McNeil management, PaineWebber and Skadden, Arps met
with representatives of Whitehall and Sullivan & Cromwell, Whitehall's legal
advisor, to answer questions from Whitehall and its advisors with respect to
some of the terms of the transaction negotiated between McNeil management and
Final Bidder 3. Final Bidder 3 had previously provided Whitehall with a copy of
the latest draft of the acquisition agreement negotiated between McNeil
management and Final Bidder 3. During the remainder of the week of February 22,
1999, Skadden, Arps and Sullivan & Cromwell continued to discuss some of the
aspects of Final Bidder 3's proposed transaction for the McNeil portfolio
raised in the February 22 meeting, including the structure of the proposed
transaction and the ownership of the Final Bidder 3 off-balance sheet
acquisition entity. On February 23, 1999, Final Bidder 3 informed McNeil
management that no progress had been made in negotiating the term sheet with
Whitehall.

   On February 24, 1999, McNeil management, PaineWebber and Skadden, Arps
contacted representatives of Whitehall and Sullivan & Cromwell. During those
discussions, McNeil management expressed their frustration in the efforts to
reach an agreement with Final Bidder 3 with respect to a possible transaction
between Final Bidder 3 and the McNeil Partnerships. McNeil management also
asked Whitehall whether it would consider entering into a transaction with the
McNeil Partnerships in which Final Bidder 3 was not a participant. Whitehall
informed McNeil management that because of its discussions with Final Bidder 3
concerning Whitehall's potential role as an equity partner with Final Bidder 3
in a transaction between Final Bidder 3 and the McNeil Partnership, Whitehall
was not willing to consider such a transaction during the time that Final
Bidder 3 and the McNeil Partnerships were negotiating a possible transaction
between them.


                                       52
<PAGE>

   On February 25, 1999, Nolan Brothers, Inc. verbally expressed an interest in
acquiring certain real estate assets owned by Fund XXVII.

   On March 1, 1999, following a telephonic special meeting, the McNeil
Investors board of directors decided to terminate discussions with Final Bidder
3 based, among other things, on the fact that Final Bidder 3 had not executed a
term sheet with Whitehall and had not paid the good-faith deposit which it had
committed to pay to Whitehall.

   On March 3, 1999, at the direction of McNeil Partners, McNeil management
advised management of Final Bidder 3, and McNeil management and PaineWebber
advised representatives of Whitehall, that discussions with Final Bidder 3 were
terminated because it was unlikely that an agreement with Final Bidder 3 would
be reached and consummated.

   Soon thereafter, McNeil management and PaineWebber contacted representatives
of Whitehall regarding the possibility of Whitehall pursuing a transaction for
the McNeil portfolio. During the month of March 1999, McNeil management,
Skadden, Arps, representatives of Whitehall and Sullivan & Cromwell held
exploratory discussions with respect to a possible transaction for the McNeil
portfolio. Also during this time, Whitehall began due diligence on the McNeil
portfolio. After conducting initial due diligence, Whitehall proposed to McNeil
management that a special purpose acquisition entity to be formed by an
affiliate of Whitehall would acquire the McNeil portfolio for a proposed
purchase price of $646,089,803, the same purchase price that had been agreed to
between McNeil management and Final Bidder 3 on November 16, 1998. Whitehall
and McNeil management discussed preliminarily the possibility of the McNeil
Affiliates receiving an equity interest in the special purpose acquisition
entity.

   On March 25, 1999, at a special meeting, the McNeil Investors board of
directors resolved to begin initial discussions with Whitehall with respect to
the preliminary terms of a transaction for the McNeil portfolio, and in
recognition of the favorable exploratory discussions with Whitehall, also
approved the form of an exclusivity letter and confidentiality agreement to be
entered into with Whitehall.

   Following the meeting of the McNeil Investors board of directors, on March
26, 1999, Whitehall, McNeil Partners, McREMI, Robert A. McNeil and Carole J.
McNeil executed the exclusivity agreement and related confidentiality
agreement. Pursuant to the terms of the exclusivity agreement, the exclusivity
period was scheduled to expire in forty-five days, on May 10, 1999, to allow
Whitehall time to complete its due diligence on the McNeil portfolio.

   On April 2, 1999, McNeil management sent a letter to Nolan Brothers
acknowledging receipt of Nolan Brothers' February 25, 1999 proposal but
informing Nolan Brothers that McNeil Partners had entered into a forty-five day
exclusivity agreement with Whitehall and therefore was unable to engage in any
discussion during this period with Nolan Brothers regarding Nolan Brothers'
interest in the McNeil Partnerships. On the same date, McNeil management sent a
similar letter to Everest acknowledging receipt of Everest's previous proposal
but informing Everest that it had entered into a forty-five day exclusivity
agreement with Whitehall and therefore was unable to engage in any discussions
with Everest during this period regarding Everest's interest in the McNeil
Partnerships.

   Appointment of the special committee

   By the end of April, in light of favorable preliminary discussions with
Whitehall, the McNeil Investors board of directors agreed to commence
negotiating mutually acceptable definitive transaction documents with Whitehall
with respect to a transaction for the McNeil portfolio. The McNeil Investors
board of directors also determined that a special, independent committee of the
McNeil Investors board of directors should be set up to participate in the
negotiation of the terms of definitive agreements with respect to the
transaction and to evaluate the transaction on behalf of the limited partners
of the McNeil Partnerships. In addition, as a result of discussions between
McNeil management and Whitehall, Whitehall had agreed that the McNeil
Affiliates

                                       53
<PAGE>

would receive an equity interest in the Whitehall acquisition entity in
consideration for their ownership interests in the McNeil Partnerships, assets
of McNeil Partners related to the McNeil Partnerships and certain assets of
McREMI. The McNeil Investors board of directors, after consultation with its
legal advisors, determined that a special independent committee was necessary
in light of the actual or potential conflicts of interest created by the
acquisition by the McNeil Affiliates of equity in WXI/McN Realty as a result of
the proposed transaction. See "--Interests of certain persons in matters to be
acted upon; conflicts of interest--Equity interest of McNeil Partners in
WXI/McN Realty."

   On May 7, 1999, the McNeil Investors board of directors increased the
authorized number of directors constituting the McNeil Investors board of
directors from three to four and appointed Paul B. Fay, Jr. as an independent
director of McNeil Investors to fill the newly created directorship. The McNeil
Investors board of directors then constituted the special committee with all of
the power and authority of the McNeil Investors board of directors (1) to
participate, through its legal counsel and financial advisor, in negotiating
the forms, terms and conditions of the definitive agreements respecting the
transaction, and (2) with the assistance of its legal counsel and financial
advisor, to review and pass upon the terms of the transaction on behalf of the
limited partners of the McNeil Partnerships. The McNeil Investors board of
directors appointed Mr. Fay as the sole member of the special committee.

   The McNeil Partnerships, on behalf of the special committee, retained
Orrick, Herrington & Sutcliffe LLP ("Orrick, Herrington") as the special
committee's legal advisor and Eastdil Realty Company as the special committee's
financial advisor. Pursuant to the engagement letter entered into between the
special committee, the McNeil Partnerships and Eastdil Realty Company, Eastdil
Realty Company agreed to review the allocation analysis performed and opinions
rendered by Stanger & Co. and, if delivered by Stanger & Co., the appraisals,
and to render to the special committee the opinions set forth in "--Opinions
and reports of financial advisors--Eastdil Realty Company opinions." See "--
Background of the transaction--Background of the auction process--Engagement of
Stanger & Co. to render the allocations."

  Engagement of Stanger & Co. to render the allocations

   Also on May 7, 1999, the McNeil Partnerships entered into an amended and
restated engagement letter with Stanger & Co. which provided that Stanger & Co.
would perform the allocation analysis, render the appraisals if requested and
render certain additional opinions as to the fairness from a financial point of
view to the holders of each class of limited partner units in each of the
McNeil Partnerships of the consideration to be received by the limited partners
in the transaction. See "--Opinions and reports of financial advisors--
Allocation analysis and opinions of Stanger & Co."

  Negotiation of definitive transaction documents with Whitehall

   On May 8, 1999, the special committee met with Orrick, Herrington and
Eastdil Realty Company to discuss the procedures that would be followed by the
special committee and the roles and responsibilities of its legal advisor and
financial advisor. Later in the meeting, McNeil management provided the special
committee with a detailed review of the auction process and the current status
of the negotiations with Whitehall. In addition, Stanger & Co. provided a
detailed verbal and written review of its activities since its engagement by
the McNeil Partnerships in January 1998, including a discussion of (1) the
history of the auction process and how that process led to Whitehall being the
proposed buyer; (2) the methodologies it was employing in connection with the
allocation analysis and opinions proposed to be delivered by Stanger & Co.; and
(3) the procedures it was following with respect to valuing each of the
properties owned by the McNeil Partnerships.

   Following the appointment of the special committee, Orrick, Herrington,
McNeil management, PaineWebber, Skadden, Arps, representatives of Whitehall,
and Sullivan & Cromwell met in person and by telephone conference call several
times during the first weeks of May 1999 to discuss open issues and to
negotiate the terms of the Master Agreement and the other transaction documents
with respect to the transaction. Among the issues being discussed were
Whitehall's obligations with respect to the funding of the

                                       54
<PAGE>

Whitehall acquisition vehicle and certain environmental, title and survey
issues that Whitehall believed existed at certain properties at that time.
Additional discussions were also held among Orrick, Herrington, McNeil
management, Skadden, Arps, representatives of Whitehall, Sullivan & Cromwell,
representatives of The Archon Group, L.P., and Arent Fox Kitner Plotkin & Kahn
PLLC ("Arent Fox"), which represented Whitehall with respect to these title and
survey issues.

   On May 10, 1999, Whitehall's exclusivity period expired. Orrick, Herrington,
McNeil management, PaineWebber, Skadden, Arps, representatives of Whitehall,
Sullivan & Cromwell, representatives of Archon, and Arent Fox continued to
discuss and negotiate the terms of the Master Agreement and the other
transaction documents.

   On May 13, 1999, Everest submitted a revised offer to purchase the self-
storage properties and the two office buildings owned by Fund XXVII for $52.0
million in cash. The Everest proposal included a fee of one-half of all real
estate commissions to be paid by Sellers, a sixty-day inspection period and
other material contingencies. The Everest proposal also included an exclusivity
provision that would have prevented the McNeil Affiliates and the McNeil
Partnerships from negotiating with other bidders, including Whitehall.

   At a telephonic meeting held in the evening of May 13, 1999, the McNeil
Investors board of directors, after consultation with the special committee and
its advisors and in recognition of the significant progress made among the
parties in negotiating the terms of the definitive transaction documents,
considered and approved a new exclusivity agreement to be entered into with
Whitehall which would extend the exclusivity period to June 4, 1999. On May 14,
1999, Whitehall, McNeil Partners, McREMI, Robert A. McNeil and Carole J. McNeil
agreed to Whitehall's prior request to extend the exclusivity period and
entered into the new exclusivity agreement.

   On May 13 and 14, 1999, lengthy discussions continued among Orrick,
Herrington, McNeil management, PaineWebber, Skadden, Arps, Sullivan & Cromwell,
representatives of Whitehall, representatives of Archon, and Arent Fox
regarding the terms and conditions of the proposed transaction documents.

   On May 20, 1999, the special committee met with Orrick, Herrington to review
the status of the negotiations with Whitehall and the current draft of the
Master Agreement. By telephone, Eastdil Realty Company provided a status report
with respect to its activities and with respect to the activities of Stanger &
Co. In addition, Orrick, Herrington reviewed with the special committee the
duties and responsibilities of a board of directors and of a special committee
in transactions such as the one proposed with Whitehall.

   On May 20 and 21, 1999, Orrick, Herrington, McNeil management, PaineWebber,
Skadden, Arps, representatives of Whitehall, Sullivan & Cromwell,
representatives of Archon, and Arent Fox met to discuss open issues and to
continue to negotiate the terms of the Master Agreement and the other
transaction documents with respect to the transaction.

   On May 24, 1999, McNeil management sent a letter to Everest acknowledging
receipt of Everest's May 13 proposal but informing Everest that the exclusivity
agreement with Whitehall had been extended and that McNeil management therefore
was unable to engage in any discussions with Everest regarding Everest's
interest in the assets of Fund XXVII.

   On May 25, 1999, representatives of Whitehall informed McNeil management
that they received approval from Whitehall's investment committee to proceed
with the transaction for the McNeil portfolio.

   Also on May 25, 1999, the special committee met with Orrick, Herrington to
review the status of the negotiations with Whitehall and the current drafts of
the Master Agreement, including the provisions regarding the general partner's
obligation to terminate the Master Agreement based upon the exercise of its
fiduciary duties owing to the limited partners, the break-up fee and the
payment of certain expenses should the transaction be terminated. Eastdil
Realty Company made a verbal and written presentation to the special

                                       55
<PAGE>

committee regarding the status of its review of the work product of Stanger &
Co. and of its independent due diligence and related analysis regarding the
allocation analysis and opinions proposed to be delivered by Stanger & Co. and
by Eastdil Realty Company as described above under "--Opinions and reports of
financial advisors." Skadden, Arps made a presentation to the special committee
regarding the pending Schofield litigation described above under "--Background
of the transaction--Background of the Schofield litigation," describing the
history of the litigation, the proposed settlement, including the involvement,
in an oversight capacity, of plaintiffs' counsel, and the schedule set by the
court to finalize the settlement.

   In addition, at the May 25, 1999 meeting of the special committee,
PaineWebber made a verbal and written presentation to the special committee
regarding:

  . PaineWebber's engagement by the McNeil Partnerships in November 1997 to
    act as exclusive financial advisor in connection with the sale of the
    McNeil portfolio,

  . PaineWebber's advice as to the structure of a proposed sale that would
    most likely maximize value for the limited partners of the McNeil
    Partnerships,

  . PaineWebber's due diligence with respect to the McNeil Partnerships and
    its assistance to McNeil management in preparing appropriate offering
    materials with respect to the proposed sale,

  . the bidding process, including the form of the bid, the selection of the
    entities to be invited to make an initial bid, the results of the initial
    bid, the solicitation of the final bids, the negotiations with the final
    bidders and the other circumstances leading to the current negotiations
    with Whitehall,

  . a comparative analysis, from a financial perspective, of the initial,
    revised and final bids, and

  . summary information with respect to indications of interest received by
    PaineWebber during the auction process with respect to certain properties
    of certain of the McNeil Partnerships.

   On May 26 and May 27, 1999, Stanger & Co., in consultation with Eastdil
Realty Company, held a number of discussions with Whitehall regarding the
percentages by which the aggregate consideration to be allocated to all of the
McNeil Partnerships taken as a whole would be allocated among the individual
McNeil Partnerships. In addition, on those dates those parties and Orrick,
Herrington, McNeil management and Skadden, Arps continued their discussions
regarding the open issues and the terms and conditions of the Master Agreement.

   On May 28, 1999, the special committee met with Orrick, Herrington to review
the status of the negotiations with Whitehall and to discuss the principal
unresolved issues, including the proposed provisions regarding the general
partner's obligation to terminate the Master Agreement based upon the exercise
of its fiduciary duties owing to the limited partners, the break-up fee and the
payment of certain expenses should the transaction be terminated. Orrick,
Herrington provided a detailed summary of certain of the provisions of the
current draft of the Master Agreement.

   On June 1, 1999, Orrick, Herrington, McNeil management, Skadden, Arps,
representatives of Whitehall, Sullivan & Cromwell, representatives of Archon,
and Arent Fox met by telephone to resolve certain material issues with respect
to the Master Agreement and the other transaction documents. At this time,
representatives of McNeil management, the special committee and Whitehall
agreed to an aggregate purchase price reduction of $1.65 million for additional
environmental issues that Whitehall's environmental consultant identified at
certain properties at that time and for the scheduled expiration of a ground
lease at one of the properties. As a result, the aggregate purchase price
offered by Whitehall was reduced to approximately $644.4 million. This purchase
price reduction was tied to each of the specifically identified properties to
which the issues related and to the respective McNeil Partnerships which owned
those properties.

   On June 2, 1999, Orrick, Herrington, McNeil management, Skadden, Arps,
Stanger & Co., Houlihan, Lokey, and Eastdil Realty Company met with
representatives of the lawyers representing the plaintiffs in the Schofield
litigation described above under "Background of the transaction--Background of
the Schofield

                                       56
<PAGE>

litigation," and with their financial advisor, to discuss in general terms the
preliminary conclusions of Stanger & Co. with respect to its proposed
allocation analysis as well as the financial analysis of Houlihan, Lokey with
respect to the value of McREMI.

   On June 3, 1999, the McNeil Investors board of directors held a meeting at
Skadden, Arps' offices in New York to hear presentations from their financial
advisors and the financial advisors to the McNeil Partnerships and to determine
whether to authorize proceeding with the transaction with Whitehall. In
attendance at the meeting were Robert A. McNeil, Carole J. McNeil, Ron K.
Taylor and Paul B. Fay, Jr., constituting the entire McNeil Investors board of
directors. Representatives of Eastdil Realty Company, Orrick, Herrington and
Skadden, Arps were also in attendance. Verbal and written presentations were
made to the McNeil Investors board of directors by representatives of Stanger &
Co. and PaineWebber, and the McNeil Investors board of directors had the
opportunity to ask questions of the representatives making the presentations.
At this point, the meeting of the McNeil Investors board of directors was
recessed and a separate meeting of the special committee was held. In
attendance at this meeting, in addition to the special committee, were Orrick,
Herrington and Eastdil Realty Company. PaineWebber was also invited to the
meeting to provide the special committee the opportunity to receive a current
update on the entire auction process and the state of the current real estate
and financial markets. Following the departure of PaineWebber, Eastdil Realty
Company provided a status report to the special committee (1) on its analysis
of the report of Stanger & Co. which had just been presented to the McNeil
Investors board of directors, and (2) on its opinions to be rendered to the
special committee covering the matters described under "--Opinions and reports
of financial advisors--Eastdil Realty Company opinions--First Eastdil Realty
Company opinion." Based on the foregoing and the presentations made at the
recessed meeting of the McNeil Investors board of directors, the special
committee concluded that negotiations with Whitehall should continue to
proceed.

   Following the meeting of the special committee, the full McNeil Investors
board of directors reconvened and received a presentation from Houlihan, Lokey
with respect to the valuation of McREMI. The McNeil Investors board of
directors had an opportunity to ask questions of the individuals making the
presentation. The special committee then recommended to the McNeil Investors
board of directors, and the McNeil Investors board of directors authorized
McNeil management, its advisors, the special committee and its advisors, to
continue to proceed with negotiations of definitive transaction documents with
Whitehall.

   During the following three weeks, Orrick, Herrington, McNeil management,
PaineWebber, Skadden, Arps, representatives of Whitehall and Sullivan &
Cromwell continued to negotiate the final issues with respect to the
transaction and the transaction documents, including issues regarding the
general partner's obligation to terminate the Master Agreement based upon the
exercise of its fiduciary duties owing to the limited partners, break-up fees
and certain transaction expenses, as well as certain remaining title and survey
issues which Whitehall believed existed on certain properties at the time.

   On June 8, 1999, Orrick, Herrington, McNeil management, Skadden, Arps,
Stanger & Co. and Houlihan, Lokey met with representatives of the lawyers
representing the plaintiffs in the Schofield litigation and with their
financial advisor to discuss further the preliminary conclusions of Stanger &
Co. with respect to its proposed allocation analysis as well as the financial
analysis of Houlihan, Lokey with respect to the value of McREMI. This meeting
was continued on June 9, 1999, and during this meeting the Schofield
plaintiffs' lawyers and their financial advisor indicated they would support
the proposed Stanger & Co. allocation analysis.

   On June 14, 1999, the special committee met by telephone with Orrick,
Herrington for the purpose of reviewing the current draft of the Master
Agreement and the principal remaining open issues, with particular emphasis on
the provisions regarding the general partner's obligation to terminate the
Master Agreement based upon the exercise of its fiduciary duties owing to the
limited partners, break-up fees and the payment of certain fees upon
termination of the Master Agreement.

<PAGE>

   On June 22, 1999, Orrick, Herrington, McNeil management, Skadden, Arps,
Sullivan & Cromwell, representatives of Whitehall, representatives of Archon,
and Arent Fox, met by telephone to attempt to resolve the remaining title and
survey issues. At this time, representatives of McNeil management, the special
committee and Archon agreed to certain per property price reconciliations in
the aggregate amount of $200,000 to be deducted on the closing date of the
transaction from the modified net working capital balances of the respective
McNeil Partnerships which own those properties. See "The Master Agreement--The
mergers--Special distribution of positive net working capital balance."

   Beginning in the late afternoon of June 23, 1999, and continuing until the
morning of June 24, 1999, Skadden, Arps, McNeil management and Sullivan &
Cromwell met to finalize remaining legal issues in the Master Agreement and the
other transaction documents. Orrick, Herrington, as a representative of the
special committee, participated in portions of this meeting by telephone.

   In the morning of June 24, 1999, Stanger & Co. rendered to the McNeil
Partnerships the opinions described under "--Opinions and reports of financial
advisors--Allocation analysis and opinions of Stanger & Co.--First Stanger &
Co. opinion," including opinions that the aggregate consideration, the
allocations of the aggregate consideration and the estimated per unit aggregate
amount to be received with respect to each class of limited partners of each of
the McNeil Partnerships is fair from a financial point of view to the holders
of each class of limited partner units in each of the McNeil Partnerships.

   Later on June 24, 1999, the special committee met by telephone with Orrick,
Herrington for the purpose of reviewing the final negotiations with Whitehall
and the final draft of the Master Agreement and certain related documents and
preparing its recommendation to the McNeil Investors board of directors.
Following a review of the final negotiations and the final form of the Master
Agreement, the special committee spoke by telephone with representatives of (1)
PaineWebber as to whether there were any developments with respect to third
parties expressing interest in the acquisition of the McNeil Partnerships, (2)
Skadden, Arps as to the status of the settlement discussions in the Schofield
litigation, (3) Stanger & Co. with respect to the opinions mentioned
above which were delivered by it to the special committee and Orrick,
Herrington earlier on June 24, 1999 and (4) Eastdil Realty Company with respect
to its opinions rendered to the special committee and dated June 24, 1999
covering the matters described under "--Opinions and reports of financial
advisors--Eastdil Realty Company opinions--First Eastdil Realty Company
opinion." Taking into account all of the foregoing, the special committee:

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of the McNeil Partnerships, and

  . recommended to the McNeil Investors board of directors the approval of
    the merger proposal.

   Following its meeting, the special committee participated by telephone in a
McNeil Investors board of directors meeting, during which the special committee
reported its above-described determination and recommendation.

   Following the report of the special committee, the McNeil Investors board of
directors, based on the recommendation of the special committee and the
opinions rendered by Stanger & Co., unanimously:

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of each of the McNeil Partnerships,

  . approved the merger proposal, and

  . determined to recommend to the limited partners of each of the McNeil
    Partnerships that they approve the merger proposal. See "--Purposes and
    reasons for the transaction," "--Effects of the transaction," "--
    Recommendations of the special committee and the McNeil Investors board
    of directors" and "--Interests of certain persons in matters to be acted
    upon; conflicts of interest."

   In the evening of June 24, 1999, WXI/McN Realty, the McNeil Partnerships,
the McNeil General Partners and McREMI entered into the Master Agreement. On
the morning of June 25, 1999, McNeil Partners issued a press release announcing
that each of the McNeil Partnerships had entered into a definitive agreement
with WXI/McN Realty.

Events subsequent to the execution of the Master Agreement

   On July 8, 1999, McNeil Partners, McREMI and Robert A. McNeil received a
letter from High River. Subject to the fulfillment of the "commencement
condition" described below, the letter stated that High River and its
affiliates would commence a tender offer for the Partnership and the other
McNeil Partnerships at the per unit prices specified below, reduced for any
distribution made with respect to the limited partner units after June 25,
1999:

The commencement condition was defined by High River as the Los Angeles County
Superior Court rejecting in its entirety the proposed settlement of the
Schofield litigation and directing further that any new settlement not be
approved without due notice to, and an opportunity to object by, the limited
partners of the McNeil Partnerships. On July 8, 1999, the Los Angeles County
Superior Court granted final approval to the settlement of the Schofield
litigation. In granting its approval, the court considered the High River
letter. See "--Background of the transaction--Background of the Schofield
litigation."

   On July 23 1999, High River and two other affiliates of Carl C. Icahn
(Unicorn Associates Corporation and Longacre Corporation), filed a complaint
for damages in the Supreme Court of the State of New York, County of New York,
entitled High River Limited Partnership, et al. v. McNeil Partners, L.P., et
al., Index No. 99 603526. The complaint is referred to in this Proxy Statement
as the "High River Complaint." The complaint named as defendants McNeil
Partners, McNeil Investors, McREMI, Robert A. McNeil and Carole J. McNeil. High
River alleges that the defendants improperly interfered with tender offers made
by High River for limited partner units in several of the McNeil Partnerships,
by, among other things, filing purportedly frivolous litigation to delay High
River's offers, issuing purportedly false and misleading statements opposing
the offers and purportedly forcing High River itself to file litigation to
enforce its rights. High River also alleges that as a result the defendants
caused High River to incur undue expense and that the defendants ultimately
prevented High River from acquiring a greater number of limited partner units.
Plaintiffs also allege that the defendants improperly excluded High River from
participating in the auction process for the sale of the McNeil Partnerships,
and otherwise took steps to prevent its participation in the auction. In
addition, plaintiffs, who are limited partners in, among others, Funds IX, X,
XI, XII, XIV, XV, XX, XXIV, XXV, XXVI and XXVII, have also sued the defendants
based on their status as opt-outs from the Schofield settlement. Plaintiffs
seek undisclosed damages and an accounting.

                                       59
<PAGE>

   On July 30, 1999, defendants filed an answer to the High River Complaint,
denying each and every material allegation contained in the High River
Complaint and asserting several affirmative defenses. Defendants have
approached the plaintiffs regarding settling the litigation, but no progress
has been made and no assurance can be given that the litigation will be
settled.

Purposes and reasons for the transaction

   The transaction represents the culmination of nearly two years' efforts by
McNeil Partners to achieve a sale of the McNeil Partnerships and distribution
of the sale proceeds to the limited partners. The purpose of the transaction is
for WXI/McN Realty to acquire the general partner interests and limited partner
interests in the McNeil Partnerships, assets of McNeil Partners related to the
McNeil Partnerships and certain assets of McREMI, while providing the limited
partners of the McNeil Partnerships with the opportunity to liquidate their
investment in the McNeil Partnerships for cash.

   The McNeil General Partners believe that the basis on which each of the
McNeil Partnerships will be acquired by WXI/McN Realty is fair to and in the
best interests of the limited partners of that McNeil Partnership. See "--
Position of McNeil Partners and Robert A McNeil regarding the transaction." The
McNeil General Partners also believe that the transaction will provide more
immediate liquidity to the McNeil Partnerships' limited partners than would
have been obtainable had the McNeil Partnerships been liquidated on a property
by property basis.

   The McNeil Investors board of directors has unanimously determined that the
merger proposal is fair to and in the best interests of each of the McNeil
Partnerships and its limited partners. In making its determination, the McNeil
Investors board of directors relied on the recommendation of a special
committee of the McNeil Investors board of directors and on a written fairness
opinion delivered to the McNeil Investors board of directors by Stanger & Co.
on behalf of the McNeil Partnerships to the effect that the aggregate
consideration, the allocations of the aggregate consideration and the estimated
per unit aggregate amount to be received with respect to each class of limited
partners of each of the McNeil Partnerships are each fair from a financial
point of view to the holders of each class of limited partner units in each of
the McNeil Partnerships. See "--Recommendations of the special committee and
the McNeil Investors board of directors; fairness of the transaction," "--
Effects of the transaction" and "--Opinions and reports of financial advisors--
Allocation analysis and opinions of Stanger & Co. --First Stanger & Co.
opinion."

   Moreover, the terms of the transaction have been reviewed and approved by
counsel to the plaintiffs in the Schofield litigation. See "--Background of the
transaction--Background of the Schofield litigation."

   Consummation of the transaction will satisfy the obligations undertaken by
McNeil Partners to liquidate the public McNeil Partnerships prior to the end of
1999. See "--Background of the transaction--Restructuring of the public McNeil
Partnerships" and "--Background of the transaction--Icahn tender offers."

   At the commencement of its engagement, PaineWebber advised McNeil Partners
that the highest price for the McNeil Partnerships and, therefore, the greatest
distribution to the limited partners of each of the McNeil Partnerships, would
likely be achieved by offering the McNeil Partnerships and McREMI together on
an all-or-none basis. See "--Background of the transaction--Structuring of the
transaction." On the basis of PaineWebber's advice, McNeil management decided
(1) to market the McNeil Partnerships, McNeil Investors, McNeil Partners and
McREMI as a single portfolio, and (2) to instruct prospective purchasers to
submit bids only for the entire portfolio. See "--Background of the
transaction--Background of the auction process--Structuring of the transaction"
and "--Background of the transaction--Background of the auction process--
Solicitation of final bids."

   Prospective purchasers also were instructed that the McNeil Partnerships
sought only cash offers for the limited partner interests in the McNeil
Partnerships. See "--Background of the transaction--Background of the auction
process--Structuring of the transaction" and "--Background of the transaction--
Background of the auction process--Solicitation of final bids." Under the
limited partnership agreements of the public McNeil Partnerships, limited
partners owning at least 80% of the outstanding limited partner units must
approve a

                                       60
<PAGE>

reorganization transaction. A reorganization transaction includes a merger or
liquidation of a McNeil Partnership in which the limited partners would receive
securities. In contrast, approval by limited partners owning only a majority of
each class of limited partner units is required to approve a merger in which
the limited partners will receive only cash. The supermajority provision was
included in the limited partnership agreements for the purpose of protecting
limited partners against the perceived abuse of "roll-up" transactions. Because
McNeil Partners believed that it would be difficult on a practical level to
obtain the 80% vote, McNeil Partners considered only those transactions in
which the limited partners of the public McNeil Partnerships would receive
cash. See "--Alternatives to the transaction."

   In addition, prospective purchasers were instructed that a transaction for
the McNeil Partnerships should be structured as a merger. McNeil Partners
believed that a merger would achieve several benefits to the limited partners
of the McNeil Partnerships that would not be achieved in a property by property
liquidation of the McNeil Partnerships. Among other things, structuring the
transaction as a merger eliminated the difficulties that would have been
encountered if prospective purchasers were allowed to purchase the more
attractive properties, leaving behind the less attractive properties that could
prove time consuming and expensive for an individual McNeil Partnership to
liquidate. Moreover, a merger also may permit the McNeil Partnerships to avoid
the payment of certain transfer taxes associated with a sale of the properties.
In addition, a merger of the McNeil Partnerships would not trigger certain due-
on-sale covenants in the mortgage debt of some of the McNeil Partnerships that
otherwise might be triggered by a sale of the individual properties of those
McNeil Partnerships. The transaction, as structured, also will allow McNeil
Partners to transfer its general partner interests in the McNeil Partnerships,
its limited partner interests in the Affiliated McNeil Partnerships, assets of
McNeil Partners and assets of McREMI to WXI/McN Realty and WXI/McN Realty's
subsidiaries in exchange for membership interests in WXI/McN Realty on a tax-
free basis and to defer substantial income tax liability that would be incurred
if there were to be a taxable sale of the properties. A taxable sale of the
properties would produce taxable gain in excess of cash proceeds because of the
relief of partnership liabilities allocated to them. See "--Federal income tax
consequences--Tax consequences to McNeil Partners."

Recommendations of the special committee and the McNeil Investors board of
directors; fairness of the transaction

 Recommendations of the special committee

   At a meeting held on June 24, 1999, the special committee, based on, among
other things, a fairness opinion delivered to the special committee by Eastdil
Realty Company and a fairness opinion delivered to the McNeil Investors board
of directors by Stanger & Co. on behalf of the McNeil Partnerships (see "--
Opinions and reports of financial advisors"):

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of each of the McNeil Partnerships; and

  . recommended to the McNeil Investors board of directors the approval of
    the merger proposal.

   In determining that the merger proposal is fair to, and in the best
interests of, the limited partners of each of the McNeil Partnerships and in
recommending to the McNeil Investors board of directors the approval of the
merger proposal, the special committee considered several factors, each of
which, in the special committee's view, supported the special committee's
determinations. Material supporting factors considered by the special committee
included:

  . The transaction satisfied McNeil Partners' obligations under the limited
    partnership agreements of each of the public McNeil Partnerships to use
    commercially reasonable efforts to complete the liquidation and
    termination of the public McNeil Partnerships by December 31, 1999. In
    addition, the transaction also satisfied the commitment of McNeil
    Partners in a settlement of the Schofield litigation to market the McNeil
    Partnerships for sale, together with McREMI, through a fair and impartial
    bidding process overseen by a national investment banking firm. See "--
    Background of the transaction--Restructuring

                                       61
<PAGE>

   of the public McNeil Partnerships," "--Background of the transaction--
   Icahn tender offers" and "--Background of the transaction--Background of
   the Schofield litigation."

  . The transaction was structured to maximize the value of each of the
    McNeil Partnerships. PaineWebber advised McNeil Partners that the highest
    and best price for the McNeil Partnerships, and therefore the greatest
    distribution to the limited partners of each of the McNeil Partnerships,
    would likely be achieved by offering for sale the McNeil Partnerships,
    McNeil Partners, McNeil Investors and McREMI as a single portfolio on an
    all-or-none basis, a structure that would allow a potential purchaser to
    acquire a large portfolio of real estate managed by a competent and
    experienced management team with a demonstrated track record of operating
    the properties over an extended period of time. This was particularly
    important because of the geographic diversity of the properties and the
    age of the improvements on most of the properties. In addition, the
    structure selected eliminated the difficulties that would have been
    encountered if prospective purchasers were allowed to purchase the more
    attractive properties, leaving behind the less attractive properties that
    could prove time consuming and expensive for an individual McNeil
    Partnership to liquidate. See "--Purposes and reasons for the
    transaction."

  . The manner in which the auction process with respect to the proposed
    transaction was structured, the method and criteria for selection of the
    potential bidders, the detailed information with respect to the
    properties furnished to the prospective bidders, the conduct of the
    initial and final bid stages of the auction process and the lengthy
    negotiations that were conducted with the final bidders, ultimately
    leading to WXI/McN Realty as the prospective purchaser. See "--Background
    of the transaction--Background of the auction process."

  . WXI/McN Realty has agreed to an aggregate purchase price for all of the
    assets being acquired in the transaction. The special committee took into
    account that Stanger & Co., the independent advisor to the McNeil
    Partnerships, made the following allocations: (1) the allocation of the
    aggregate consideration between the management assets of McREMI, on the
    one hand, and the McNeil Partnerships as a group, on the other hand; (2)
    the allocation of the aggregate consideration to each individual McNeil
    Partnership; and (3) the allocation of the aggregate consideration
    allocated to each individual McNeil Partnership among the general partner
    interest in that McNeil Partnership, other assets of McREMI related to
    that McNeil Partnership and each class of limited partner units in that
    McNeil Partnership. The allocations and the methodology of the
    allocations are described in more detail in "--Opinions and reports of
    financial advisors--Allocation analysis and opinions of Stanger & Co.--
    Stanger & Co. allocation analysis" and the dollar values of the
    individual allocations are set forth in Table 2.

  . If a participating McNeil Partnership has a positive net working capital
    balance on the closing date of the transaction, limited partners of that
    participating McNeil Partnership will receive their pro rata share of a
    special distribution of the positive net working capital balance. The net
    working capital balance of each of the McNeil Partnerships will be
    calculated in accordance with the Master Agreement and will be based on a
    modified net working capital balance of the McNeil Partnership estimated
    as of the closing date. This special distribution will be made in
    accordance with the provisions of that McNeil Partnership's limited
    partnership agreement governing distributions of surplus cash, except
    that the general partner of that McNeil Partnership will not receive any
    part of the special distribution.

  . The opinion dated June 24, 1999 of Stanger & Co. to the effect that, as
    of the date of the opinion, and subject to the assumptions,
    qualifications and limitations set forth in the opinion, each of the
    aggregate consideration, the allocations of the aggregate consideration
    and the estimated per unit aggregate amount to be received with respect
    to each class of limited partners of each of the McNeil Partnerships is
    fair from a financial point of view to the holders of each class of
    limited partner units in each of the McNeil Partnerships. See "--Opinions
    and reports of financial advisors--Allocation analysis and opinions of
    Stanger & Co.--First Stanger & Co. opinion." In addition, the special
    committee has also taken into account the opinion dated     , 1999 of
    Stanger & Co. in which Stanger & Co. rendered

                                       62
<PAGE>

   fairness opinions with respect to additional matters. See "--Opinions and
   reports of financial advisors--Allocation analysis and opinions of Stanger
   & Co.--Second Stanger & Co. opinion."

  . The Stanger & Co. analysis concluded that the estimated per unit
    aggregate amount, including both the merger consideration and the special
    distribution, to be received with respect to each class of limited
    partners of each of the McNeil Partnerships upon the closing of the
    transaction was greater than (1) the going concern value per limited
    partner unit in that McNeil Partnership, (2) the net asset value per
    limited partner unit in that McNeil Partnership and (3) the liquidation
    value per limited partner unit in that McNeil Partnership. See Table 1
    and "--Alternatives to the transaction."

  . The opinion dated June 24, 1999 of Eastdil Realty Company, which was
    engaged by the McNeil Partnerships for the benefit of the special
    committee as the financial advisor to the special committee, to the
    effect that, as of the date of the opinion, and subject to the
    assumptions, qualifications and limitations set forth in the opinion,
    each of the aggregate consideration, the allocations of the aggregate
    consideration and the estimated per unit aggregate amount to be received
    with respect to each class of limited partners of each of the McNeil
    Partnerships is fair from a financial point of view to the holders of
    each class of limited partner units in each of the McNeil Partnerships.
    See "--Opinions and reports of financial advisors--Eastdil Realty Company
    opinions--First Eastdil Realty Company opinion." In addition, the special
    committee has also taken into account the opinion dated        , 1999 of
    Eastdil Realty Company in which Eastdil Realty Company rendered fairness
    opinions with respect to additional matters. See "--Opinions and reports
    of financial advisors--Eastdil Realty Company opinions--Second Eastdil
    Realty Company opinion."

  . The verbal and written presentation of Houlihan, Lokey, the financial
    advisor to the McNeil Affiliates, that concluded that the total
    consideration that would be fairly allocable to McREMI as determined by
    Stanger & Co. was at or below the low end of the range of value estimated
    by Houlihan, Lokey. See "--Opinions and reports of financial advisors--
    Allocation analysis and opinions of Stanger & Co.-- Stanger & Co.
    allocation analysis."

  . The fact that the lawyers representing the plaintiffs in the Schofield
    litigation, in connection with settlement proceedings relating to that
    litigation, oversaw the auction process, including the allocation
    analysis rendered by Stanger & Co. This followed (1) several meetings
    plaintiffs' counsel had with Stanger & Co. during which they received
    detailed verbal and written presentations with respect to the allocation
    analysis and were given the opportunity to ask questions and (2) several
    meetings of plaintiffs' financial advisor with Stanger & Co. during which
    the financial advisor was given the opportunity to ask questions and
    examine the documentation forming the basis of the allocation analysis.
    See "--Background of the transaction--Background of the Schofield
    litigation."

  . The identity of the proposed purchaser and its affiliates and the ability
    of WXI/McN Realty to consummate the transaction on the terms specified in
    the Master Agreement.

  . The provisions in the Master Agreement allowing each of the McNeil
    Partnerships to terminate its participation in the transaction if, in the
    exercise of the good faith judgment of the general partner as to its
    fiduciary duties to its limited partners, the general partner of that
    McNeil Partnership determined that termination was required by reason of
    a superior acquisition proposal being made by a third party for that
    McNeil Partnership. See "The Master Agreement--Termination of the Master
    Agreement--Right to terminate the Master Agreement with respect to one or
    more McNeil Partnerships." The special committee recognized that any such
    termination would require the payment by that terminating McNeil
    Partnership to WXI/McN Realty of a break-up fee and certain reimbursable
    expenses. See "The Master Agreement--Fees and expenses."

  . The terms and conditions of the Master Agreement, taken as a whole, were
    favorable to the limited partners of the McNeil Partnerships and thus
    supported the special committee's conclusion that the merger proposal is
    fair to, and in the best interests of, the limited partners of the McNeil
    Partnerships.

  . In allocating the aggregate consideration, Stanger & Co. took the
    position that the deficit restoration obligations of the general partners
    of the McNeil Partnerships were required to be paid to the McNeil
    Partnerships. As a result, the aggregate consideration allocated by
    Stanger & Co. to the general partner interests in each of the McNeil
    Partnerships is net of the estimated deficit restoration obligation with
    respect to that McNeil Partnership. See "--Opinions and reports of
    financial advisors--Allocation analysis and opinions of Stanger & Co.--
    Stanger & Co. allocation analysis.

  . In allocating the aggregate consideration, Stanger & Co. took the
    position that no asset disposition fees were payable by any of the McNeil
    Partnerships to the McNeil General Partners as a result of the
    transaction. In a liquidation, the limited partnership agreements of some
    of the public McNeil Partnerships provide that McNeil Partners is
    entitled to receive an asset disposition fee equal to 3% of the gross
    sales price of each property sold in connection with a liquidation of
    that McNeil Partnership. No asset disposition fees will be paid by any of
    the McNeil Partnerships as a result of the transaction.

  . Each of the McNeil General Partners has agreed to irrevocably,
    unconditionally and absolutely waive any and all rights it may have to
    indemnification, contribution or reimbursement from any of the
    participating McNeil Partnerships, whether under the limited partnership
    agreement, any contractual arrangement, applicable law or otherwise, with
    respect to those matters for which McNeil Partners has agreed to
    indemnify WXI/McN Realty's managing member and some of its affiliates.
    See "Other Agreements Between the McNeil Affiliates and Affiliates of
    WXI/McN Realty--Indemnification and pledge agreement."

  . Upon the completion of the transaction, the limited partners of the
    participating McNeil Partnerships, other than the Affiliated McNeil
    Partnerships, would receive cash in exchange for their limited partner
    units and, accordingly, those limited partners would no longer bear the
    risks inherent in the ownership of real property such as fluctuations in
    occupancy rates, operating expenses and rental rates, which in turn may
    be affected by general and local economic conditions, the supply and
    demand for properties of the type owned by the McNeil Partnerships and
    federal and local laws and regulations affecting the ownership and
    operation of real estate.

  . Commencing with the tax year following the tax year in which the closing
    of the transaction occurs, the limited partners of the participating
    McNeil Partnerships no longer will include in their federal and state
    income tax returns the various items of income, loss, deduction and
    credit, as previously reported on Schedule K-1s, from the participating
    McNeil Partnerships.

  . As to each McNeil Partnership, approval of the merger proposal requires
    the affirmative vote of limited partners holding greater than 50% of each
    class of limited partner units in that McNeil Partnership outstanding as
    of the record date.

  . Under the California Revised Limited Partnership Act, a limited partner
    of some of the McNeil Partnerships [additional disclosure for Funds XX-
    XXVII: including the Partnership,] who does not wish to accept the merger
    consideration may dissent from the merger proposal and require that
    McNeil Partnership to purchase for cash, at their fair market value, the
    limited partner units owned by that limited partner, if that McNeil
    Partnership participates in the transaction, the limited partner does not
    vote for the merger proposal, and the limited partner follows specific
    procedures set forth in the California Revised Limited Partnership Act.

   In determining that the merger proposal is fair to, and in the best
interests of, the limited partners of each of the McNeil Partnerships and in
recommending to the McNeil Investors board of directors the approval of the
merger proposal, the special committee also considered factors, which, in the
special committee's view, did not support the special committee's
determinations. Material negative factors considered by the special committee
included:

  . Following the transaction, the limited partners of each participating
    McNeil Partnership, other than the Affiliated McNeil Partnerships, will
    cease to participate in future earnings or growth, if any, of that McNeil
    Partnership or benefit from increases, if any, in the value of that
    McNeil Partnership.

  . The transaction involves the entire McNeil portfolio, including all of
    the McNeil Partnerships, assets of McNeil Partners related to the McNeil
    Partnerships and certain assets of McREMI. At the

                                       64
<PAGE>

   commencement of PaineWebber's engagement, McNeil Partners determined to
   structure the transaction to include certain assets of McREMI based on
   PaineWebber's belief at that time that the highest price for the McNeil
   Partnerships, and therefore the greatest distribution to the limited
   partners of each of the McNeil Partnerships, would likely be achieved by
   offering for sale the McNeil Partnerships and McREMI as a single entire
   portfolio on an all-or-none basis. See "--Background of the transaction--
   Background of the auction process--Structuring of the transaction."
   However, it is possible that the limited partners of a McNeil Partnership
   could have received more consideration than what they will receive in the
   proposed transaction with WXI/McN Realty if that McNeil Partnership were
   to be sold or liquidated in a transaction separate from a transaction
   involving other McNeil Partnerships and/or the assets of McREMI.

  . The limited partners of each participating McNeil Partnership will forego
    alternatives to the transaction. These alternatives include a separate
    sale of all of the assets of that McNeil Partnership and subsequent
    liquidation of that McNeil Partnership or the continuation of that McNeil
    Partnership as a publicly held McNeil Partnership. See "--Alternatives to
    the transaction."

  . There are numerous conditions to WXI/McN Realty's and Sellers'
    obligations to consummate the transaction. No assurance can be given that
    the transaction will be consummated. See "The Master Agreement--
    Conditions to closing."

  . The Master Agreement provides that in some circumstances WXI/McN Realty
    will receive a break-up fee, calculated on a partnership by partnership
    basis, up to an aggregate maximum of $18.0 million if the Master
    Agreement is terminated. The amount of the break-up fee payable by the
    Partnership is $    . The obligation of a McNeil Partnership to pay a
    break-up fee may discourage third party offers for that McNeil
    Partnership and may adversely affect the ability of that McNeil
    Partnership to engage in another transaction following termination of the
    Master Agreement in respect of that McNeil Partnership. In addition, a
    McNeil Partnership may be obligated to pay a break-up fee even if it has
    not entered into a definitive agreement for or consummated another
    transaction. As a result, payment of the break-up fee may have an adverse
    impact on the financial condition of that McNeil Partnership. See "The
    Master Agreement--Fees and expenses--Partnership break-up fee."

  . McNeil Partners has actual or potential conflicts of interest in
    connection with recommending the approval of the merger proposal to the
    limited partners of the McNeil Partnerships. See "--Effects of the
    transaction--Benefits and detriments of the transaction to the McNeil
    Affiliates" and "--Interests of certain persons in matters to be acted
    upon; conflicts of interest."

  . Each of the McNeil Partnerships did not have separate representation in
    the transaction. In structuring the transaction, the special committee
    represented the interests of the limited partners of all of the McNeil
    Partnerships as a group and Stanger & Co. served as independent advisor
    to all of the McNeil Partnerships. If separate representation had been
    arranged for each McNeil Partnership, issues unique to the value of a
    given McNeil Partnership might have received greater attention during the
    structuring of the transaction, and the terms of the transaction might
    have been different with respect to that McNeil Partnership.

  .  If limited partners owning more than 50% of each class of limited
    partner units in a McNeil Partnership vote for the merger proposal, their
    approval will bind all limited partners of that McNeil Partnership.
    Therefore, a limited partner of a McNeil Partnership may vote against the
    merger proposal and nevertheless have its limited partner units converted
    into the right to receive cash in the transaction if the requisite vote
    of the limited partners of that McNeil Partnership is obtained.

  . The transaction, as structured, will allow McNeil Partners to make the
    contributions of its interests in the McNeil Partnerships and the assets
    of McNeil Partners and McREMI being contributed to WXI/McN Realty on a
    tax-free basis and to defer substantial tax liability that would be
    incurred if there were to be a taxable sale of the properties. In
    contrast, limited partners will recognize gain or loss on the conversion
    of their limited partner units into cash in the merger [additional
    disclosure for Funds

                                      65
<PAGE>

   XX-XXVI: or on receipt of cash pursuant to the exercise of dissenters'
   rights]. In general, the special distribution will not be taxable and will
   be treated as a return of capital to the limited partner; provided,
   however that to the extent that the special distribution received by a
   limited partner exceeds that limited partner's adjusted tax basis in all
   of its limited partner units that excess will be taxable and will be
   treated as capital gain.

  . In determining whether the requisite vote of the limited partners of a
    McNeil Partnership has been obtained, limited partner units held by
    McNeil Partners and its affiliates will not be excluded. McNeil Partners
    and its affiliates intend to vote all of the limited partner units
    beneficially owned by them in each of the McNeil Partnerships for the
    merger proposal with respect to that McNeil Partnership. [Additional
    disclosure for Funds IX-XI, XIV, XV, XX, XXV-XXVII: As of the record
    date, McNeil Partners and some of its affiliates beneficially owned an
    aggregate of     limited partner units in the Partnership, representing
    in the aggregate approximately  % of the limited partner units in the
    Partnership outstanding as of the record date. [Additional disclosure for
    Fund XXIII: As of the record date, McNeil Partners beneficially owned an
    aggregate of    growth/shelter units in the Partnership, representing in
    the aggregate approximately  % of the growth/shelter units outstanding as
    of the record date.]

  . Limited partners of some of the McNeil Partnerships [additional
    disclosure for Funds IX-XII, XIV, XV, XXVII: including the Partnership,]
    do not have any dissenters' rights or other rights of appraisal, under
    the state law which governs those McNeil Partnerships, the limited
    partnership agreements of those McNeil Partnerships or otherwise, in
    connection with the merger proposal. Therefore, dissenting limited
    partners do not have the right to have their limited partner units
    appraised if they disapprove of the action of the limited partners that
    voted for the merger proposal. The limited partners of other McNeil
    Partnerships [additional disclosure for Funds XX-XXVI: including the
    Partnership,] are entitled to the benefits of dissenters' rights as
    provided under applicable state law.

   In the special committee's view, these countervailing factors were not
sufficient, either individually or in the aggregate, to outweigh the benefits
of the proposed transaction to the limited partners of the McNeil Partnerships.

   In view of the wide variety of factors considered in connection with its
evaluation of the transaction and the merger proposal, the special committee
did not find it practicable to, and did not attempt to, quantify, rank or
otherwise assign relative weights to the specific factors it considered in
reaching its determination and recommendation.

 Recommendations of the McNeil Investors board of directors

   Following the meeting of the special committee, on June 24, 1999, the McNeil
Investors board of directors:

  . determined that the merger proposal is fair to, and in the best interests
    of, the limited partners of each of the McNeil Partnerships;

  . approved the merger proposal; and

  . determined to recommend to the limited partners of each of the McNeil
    Partnerships that they approve the merger proposal.

   The McNeil Investors board of directors based its recommendation on, among
other things, the recommendation of the special committee, the factors
enumerated above that were considered by the special committee and the fairness
opinion delivered on June 24, 1999 to the McNeil Investors board of directors
by Stanger & Co. on behalf of the McNeil Partnerships. See "--Opinions and
reports of financial advisors--Allocation analysis and opinions of Stanger &
Co.--First Stanger & Co. opinion" and "--Recommendations

                                       66
<PAGE>

of the special committee and the McNeil Investors board of directors; fairness
of the transaction--Recommendations of the special committee." Limited partners
of the Partnership should be aware that members of the McNeil Investors board
of directors may have actual or potential conflicts of interest in making their
determinations and recommendation. The special committee was formed in part to
address these conflicts of interest. See "--Background of the transaction--
Background of the auction process--Appointment of the special committee," "--
Purposes and reasons for the transaction" and "--Interests of certain persons
in the matters to be acted upon; conflicts of interest."

Alternatives to the transaction

   The McNeil Investors board of directors' assessment of the fairness of the
transaction was based on a review of different alternatives that were
available. The McNeil Investors board of directors considered two alternatives
to the merger: (1) liquidation of the Partnership and distribution of the net
cash proceeds of the liquidation and (2) continuation of the business of the
Partnership. The McNeil Investors board of directors has not considered any
liquidation or other form of transaction in which the limited partners of the
Partnership would receive anything other than cash. See "--Background of the
transaction--Background of the auction process--Structuring of the transaction"
and "--Background of the transaction--Background the auction process--
Solicitation of final bids" and "--Purposes and effects of the transaction."

   Under the limited partnership agreements of the public McNeil Partnerships,
limited partners owning at least 80% of the outstanding limited partner units
must approve a reorganization transaction. A reorganization transaction
includes a merger or liquidation of the McNeil Partnership in which the limited
partners of the McNeil Partnership would receive securities. In contrast,
approval by limited partners owning only a majority of each class of limited
partner units is required to approve a merger in which the limited partners
will receive only cash. The supermajority provision was included in the limited
partnership agreements for the purpose of protecting limited partners against
the perceived abuse of "roll-up" transactions. Because McNeil Partners believed
that it would be difficult on a practical level to obtain the 80% vote, the
McNeil Investors board of directors considered only those transactions in which
the limited partners of the public McNeil Partnerships would receive cash.

 Liquidation

   An alternative to the transaction considered by the McNeil Investors board
of directors was to liquidate the Partnership's assets, distribute the net cash
proceeds of the liquidation to the partners and then dissolve the Partnership.

   In a liquidation, McNeil Partners would market the sale of the Partnership's
properties and, if a potential purchaser is interested in purchasing a property
or properties, McNeil Partners would negotiate and enter into an agreement for
the sale of the property or properties. If a sale of properties would
constitute a sale of all or substantially all of a McNeil Partnership's
properties, McNeil Partners would be required to obtain the approval of limited
partners holding at least 50% of the outstanding limited partner units before
the sale could close. If the limited partners approved the sale and the sale
was closed, McNeil Partners would proceed to liquidate the Partnership in
accordance with the provisions of the Partnership's limited partnership
agreement and [for Funds IX-XII, XIV, XV, XX-XXVI: California] [for Fund XXVII:
Delaware] law, which governs the Partnership.

   [For Funds IX-XII: Pursuant to the limited partnership agreement of the
Partnership, in a liquidation, McNeil Partners must distribute the liquidation
proceeds in the following order:

  . First, to the payment of creditors of the Partnership;

  . Second, to the repayment of any outstanding loans made by McNeil Partners
    to the Partnership;

  . Third, after McNeil Partners sets aside funds to pay liquidation expenses
    and reserves for contingencies which McNeil Partners believes are
    necessary, to McNeil Partners in an amount equal to the management
    incentive distribution; and

                                       67

  . Fourth, the remainder to the limited partners, pro rata according to the
    number of limited partner units owned by the limited partners.]

   [For Funds XIV, XV, XX: Pursuant to the limited partnership agreement of the
Partnership, in a liquidation, McNeil Partners must distribute the liquidation
proceeds in the following order:

  . First, to the payment of creditors of the Partnership;

  . Second, to the repayment of any outstanding loans made by McNeil Partners
    to the Partnership;

  . Third, after McNeil Partners sets aside funds to pay liquidation expenses
    and reserves for contingencies which McNeil Partners believes are
    necessary, to McNeil Partners and the limited partners in proportion to
    their positive capital accounts after the net liquidation proceeds are
    allocated to their capital accounts.]

   [For Fund XXI: Pursuant to the limited partnership agreement of the
Partnership, in a liquidation, McNeil Partners must distribute the liquidation
proceeds in the following order:

  . First, to the payment of creditors of the Partnership;

  . Second, to the repayment of any outstanding loans made by McNeil Partners
    to the Partnership;

  . Third, after McNeil Partners sets aside funds to pay liquidation expenses
    and reserves for contingencies which McNeil Partners believes are
    necessary, to McNeil Partners and the limited partners in proportion to
    their positive capital accounts after the net liquidation proceeds are
    allocated to their capital accounts.

   In the Partnership, each limited partner owns either current income units or
growth/shelter units. Limited partners are entitled to a specified priority
return on their investment in the Partnership depending upon whether they own
current income units or growth/shelter units and, as a result, the liquidation
distributions to limited partners would differ based on the type of units
owned.]

   [For Funds XXII, XXIII: Pursuant to the limited partnership agreement of the
Partnership, in a liquidation, McNeil Partners must distribute the liquidation
proceeds in the following order:

  . First, to the payment of creditors of the Partnership;

  . Second, to the repayment of any outstanding loans made by McNeil Partners
    to the Partnership;

  . Third, after McNeil Partners sets aside funds to pay liquidation expenses
    and reserves for contingencies which McNeil Partners believes are
    necessary, to McNeil Partners and the limited partners in proportion to
    their positive capital accounts after the net liquidation proceeds are
    allocated to their capital accounts.

   In the Partnership, each limited partner owns either current income units or
growth/shelter units. Limited partners are entitled to a specified priority
return on their investment in the Partnership depending upon whether they own
current income units or growth/shelter units and, as a result, the liquidation
distributions to limited partners would differ based on the type of units
owned.

  . In addition, under the limited partnership agreement, McNeil Partners is
    required to distribute to limited partners distributable cash from sales
    or refinancings in an amount sufficient to allow payment of income tax
    attributable to the sale which resulted in the generation of cash.]

   [For Funds XXIV-XXVII: Pursuant to the limited partnership agreement of the
Partnership, in a liquidation, McNeil Partners must distribute the liquidation
proceeds in the following order:

  . First, to the payment of creditors of the Partnership;

  . Second, to the repayment of any outstanding loans made by McNeil Partners
    to the Partnership;

  . Third, after McNeil Partners sets aside funds to pay liquidation expenses
    and reserves for contingencies which McNeil Partners believes are

   to their positive capital accounts after the net liquidation proceeds are
   allocated to their capital accounts.]

   [For Funds IX-XII, XIV, XV, XX, XXIV-XXVII: Stanger & Co. estimated that the
distribution amount to limited partners in a liquidation, after payments are
made to creditors and to McNeil Partners for repayment of outstanding loans, if
any, and the management incentive distribution, would be $      per limited
partner unit. See Table 1.]

   [For Funds XXI-XXIII: Stanger & Co. estimated that the distribution amount
to limited partners in a liquidation, after payments are made to creditors and
to McNeil Partners for repayment of outstanding loans, if any, would be $
per current income unit and $      per growth/shelter unit.]

   Benefits of liquidation to the limited partners

   The McNeil Investors board of directors considered the primary benefits of a
liquidation to be the following:

  . Through a liquidation, the Partnership would provide for a final
    disposition and liquidation of its partners' interests in the
    Partnership. Limited partners in the Partnership would receive cash
    liquidation proceeds.

  . A liquidation would satisfy the obligations undertaken by McNeil Partners
    to liquidate the Partnership. See "--Background of the transaction--
    Restructuring of the public McNeil Partnerships" and "--Background of the
    transaction--Icahn tender offers."

  . In a liquidation, the Partnership's limited partnership agreement
    requires McNeil Partners to restore any deficiency in its capital account
    if the assets available for distribution upon the dissolution and
    termination of the Partnership are insufficient to allow distributions to
    the limited partners of the Partnership of amounts equal to the then
    positive balances in their capital accounts.

  . Pursuant to the limited partnership agreement of the Partnership, McNeil
    Partners would be required to contribute in cash to the capital of the
    Partnership an amount equal to the lesser of (a) the deficiency in McNeil
    Partners' capital account and (b) [for all except Fund IX: 1.01% of the
    excess of the amount in cash contributed by the limited partners to the
    capital of the Partnership for limited partner units over the capital
    contributions of McNeil Partners] [for Fund IX: the amount needed so that
    distributions may be made to limited partners in the Partnership in an
    amount equal to the then positive balances in their capital accounts].
    The deficit restoration obligation of McNeil Partners with respect to the
    Partnership, estimated by Arthur Andersen LLP, based upon a hypothetical
    sale of the properties and liquidation of the Partnership at March 31,
    1999, is approximately $    . Arthur Andersen LLP's estimate was based,
    in part, on limited historical tax records prepared by other accounting
    firms. Sufficient records did not exist such that Arthur Andersen LLP
    could test the accuracy of prior accountant's work. Further, this
    estimate was based on the Partnership's projections of 1999 operating
    results through March 31, 1999 and on hypothetical asset sale/partnership
    liquidation information provided by Stanger & Co. Arthur Andersen LLP has
    not audited or opined on the projected results of operations or financial
    information relating to such hypothetical sale/liquidation.

  Disadvantages of liquidation to the limited partners

   When comparing a liquidation to the proposed transaction, the McNeil
Investors board of directors also considered that the proposed transaction
provides the same benefits as described in the bullet points above, including
that the allocations of the aggregate consideration in the transaction to each
class of limited partner units in each of the McNeil Partnerships includes an
amount equal to the general partner's estimated deficit restoration obligation,
if any, to that McNeil Partnership. See "--Purposes and reasons for the
transaction" and

                                       69
<PAGE>

"--Opinions and reports of financial advisors--Allocation analysis and opinions
of Stanger & Co.--Stanger & Co. allocation analysis."

   Based on this consideration and the factors described below, the McNeil
Investors board of directors concluded that the disadvantages of liquidating
the Partnership on a property by property basis outweighed the benefits of
liquidating the Partnership. Specifically, the McNeil Investors board of
directors considered the following disadvantages of liquidating the
Partnership:

  . There can be no assurance that McNeil Partners would be able to sell the
    Partnership's properties for prices that would result in consideration to
    the limited partners that is equal or greater than the consideration that
    it is estimated they will receive in the transaction.

  . Based on the analysis by Stanger & Co., it is anticipated that limited
    partners of the Partnership will receive more cash proceeds per limited
    partner unit in the proposed transaction than they would have received in
    a liquidation. Based on the analysis of Stanger & Co., it is anticipated
    that limited partners in the Partnership would receive an aggregate
    amount of approximately [for all except FundsXXI-XXIII: $     per limited
    partner unit] [for Funds XXI-XXIII: $   per current income unit and $
    per growth/shelter unit], in a liquidation and will receive an estimated
    aggregate amount of approximately [for all except Funds XXI-XXIII: $
    per limited partner unit] [for Funds XXI-XXIII: $   per current income
    unit and $   per growth/shelter unit] in the proposed transaction,
    including the estimated per unit special distribution. See "Liquidation
    Value" and "Total Per Unit Estimate" in Table 1. As discussed above, the
    "Total Per Unit Estimate" of the Partnership includes an amount equal to
    McNeil Partners' estimated deficit restoration obligation, if any, to the
    Partnership. See "--Opinions and reports of financial advisors--
    Allocation analysis and opinions of Stanger & Co.--Stanger & Co.
    allocation analysis."

  . In addition, based on real estate value estimates of the Partnership's
    portfolio included in the analysis by Stanger & Co., it is anticipated
    that the cash proceeds per limited partner unit to be received in the
    proposed transaction exceed the Partnership's net asset value per limited
    partner unit. Based on the analysis of Stanger & Co., it is anticipated
    that limited partners in the Partnership will receive an estimated
    aggregate amount of approximately [for all except Funds XXI-XXIII: $
    per limited partner unit] [for Funds XXI-XXIII: $   per current income
    unit and $   per growth/shelter unit] in the proposed transaction,
    including the estimated per unit special distribution. The net asset
    value per limited partner unit in the Partnership, based on the analysis
    of Stanger & Co., is approximately [for all except Funds XXI-XXIII: $
    per limited partner unit] [for Funds XXI-XXIII: $   per current income
    unit and $   per growth/shelter unit]. See "Net Asset Value" and "Total
    Per Unit Estimate" in Table 1.

  . McNeil Partners believes that the transaction will provide more immediate
    liquidity to the Partnership's limited partners than would have been
    obtainable had the Partnership been liquidated on a property by property
    basis. Limited partners would not receive distributions in a liquidation
    as quickly as they would in the transaction. Distributions would be
    payable only after the sale of the properties. There is no assurance that
    the properties of the Partnership could be sold at prices comparable to
    those in the transaction.

  . If the Partnership determined to sell all of its properties and
    liquidate, it would not be able to distribute all of the liquidation
    proceeds immediately after the sale. Under the Partnership's limited
    partnership agreement, McNeil Partners has the authority to set aside net
    proceeds from liquidation as well as other working capital of the
    Partnership to pay creditors, including creditors who may have a
    contingent claim against the Partnership. The actual timing and amount of
    distributions would be subject to McNeil Partners' determination of when
    the reserves set aside are no longer necessary. Accordingly, there could
    be no assurance as to the precise timing or amount of distributions to
    the limited partners.

  . Limited partners would be required to continue holding interests in the
    Partnership until all contingent liabilities had been settled.

  . [Additional disclosure for Funds XX-XXVII: In a liquidation, the limited
    partnership agreement of the Partnership provides that McNeil Partners
    would be entitled to receive an asset disposition fee equal to 3% of the
    gross sales price of each property sold by the Partnership. In allocating
    the aggregate consideration in the transaction, Stanger & Co. has assumed
    that no asset disposition fee is payable by the Partnership to McNeil
    Partners. See "--Effects of the transaction--Benefits and detriments of
    the transaction to the McNeil Affiliates." No asset disposition fee will
    be paid by the Partnership as a result of this transaction.]

  . Prior to the maturity date of the mortgage debt on some of the
    Partnership's properties, McNeil Partners will need to either sell those
    properties or refinance the mortgage debt. There is no assurance that
    McNeil Partners would be able to refinance the mortgage debt on terms
    that are as favorable or more favorable than the terms of the existing
    mortgage debt. In addition, the obtaining of new mortgages could preclude
    the sale of the Partnership's properties because of the terms of the
    mortgage and the costs of terminating the mortgage.

  . [Additional disclosure for Funds XX-XXVI: Limited partners would not be
    entitled to dissenters' rights in a liquidation. Therefore, limited
    partners would not have rights under the California Revised Limited
    Partnership Act to contest the amount to be received in a liquidation.]

  . Until the properties of the Partnership are sold and the Partnership is
    liquidated and terminated, limited partners would continue to receive
    Schedule K-1s from the Partnership, and the Partnership would continue to
    have SEC and tax reporting obligations.

  . Depending on the value of the properties to be sold, it may not be
    economically feasible for McNeil Partners to obtain a fairness opinion
    with respect to the sale of the Partnership's properties preceding a
    liquidation.

 Continued ownership of the Partnership

  Benefits of continued ownership

   Another alternative to the transaction would be to continue the Partnership
in accordance with its existing business plan, with the Partnership continuing
to be owned by the limited partners and McNeil Partners. This will be the
result if the Partnership does not participate in the transaction. The McNeil
Investors board of directors considered the primary benefits of continuing the
business of the Partnership to be as follows:

  . Limited partners of the Partnership would have the potential to continue
    to receive indefinitely semiannual distributions of net cash flow arising
    from operations and the sale or refinancing of the Partnership's
    properties.

  . Continued ownership of the Partnership by the limited partners and McNeil
    Partners affords the limited partners of the Partnership with the
    opportunity to participate in any future appreciation in the
    Partnership's properties.

  . Continued ownership would mean that there would be no change in the
    nature of the investment of the limited partners. Therefore, continued
    ownership would avoid whatever disadvantages might result from a change
    in the nature of the investment of the limited partners, including any
    disadvantages as a result of the proposed transaction.

  Disadvantages of continued ownership

   The McNeil Investors board of directors concluded that disadvantages of
continuation of the Partnership outweighed the benefits of continuation of the
Partnership. Specifically, the McNeil Investors board of directors considered
the following disadvantages of continuing the Partnership:

  . Based on an analysis by Stanger & Co., it is anticipated that the going
    concern value of the Partnership per limited partner unit would be less
    than the estimated per unit aggregate amount to be received in the
    proposed transaction. The going concern value of the Partnership as
    determined by Stanger & Co. is [for all except Funds XXI-XXIII: $    per
    limited partner unit] [for Funds XXI-XXIII: $   per

                                       71
<PAGE>

   current income unit and $    per growth/shelter unit] and the estimated
   aggregate amount in the transaction to be received by limited partners is
   approximately [for all except Funds XXI-XXIII: $    per limited partner
   unit] [for Funds XXI-XXIII: $    per current income unit and $    per
   growth/shelter unit], including the estimated special distribution. See
   "Going Concern Value" and "Total Per Unit Estimate" in Table 1.

  . Under the Partnership's limited partnership agreement, McNeil Partners
    agreed to commence a liquidation of the properties of the Partnership
    seven years after the Partnership's restructuring date and to use
    commercially reasonable efforts to complete the liquidation and
    termination of the Partnership by December 31, 1999. Continuation of the
    Partnership would not have satisfied the obligations undertaken by McNeil
    Partners to liquidate the Partnership. See "--Background of the
    transaction--Restructuring of the public McNeil Partnerships" and "--
    Background of the transaction--Icahn tender offers."

  . If the merger is not approved and the Partnership is continued, limited
    partners will not have any assurance of when or if another liquidation
    transaction will occur. In addition, continued ownership of the
    Partnership by the limited partners would fail to secure the benefits to
    the limited partners that are expected to result from the transaction,
    including providing immediate liquidity to the limited partners of their
    investment in the McNeil Partnerships.

  . The limited partners would not have the opportunity to liquidate their
    investment in the Partnership other than pursuant to sales of their
    limited partner units. At present, there is no established public trading
    market for the limited partner units in the Partnership and liquidity is
    limited to sporadic private sales or tender offers for limited partner
    units, both of which are generally at a substantial discount to the
    estimated per unit aggregate amount to be received in the transaction,
    including the merger consideration and estimated special distribution,
    and often involve only a limited number of limited partner units. See the
    "Private Sales Weighted Average" and "Tender Offer Ranges" in Table 1.

  . The Partnership's limited partners would continue to own limited partner
    units in the Partnership and therefore would continue to be exposed to
    the risks inherent in the ownership of real property, such as
    fluctuations in occupancy rates, operating expenses and rental rates,
    which in turn may be affected by general and local economic conditions,
    the supply and demand for properties of the type owned by the Partnership
    and federal and local laws and regulations affecting the ownership and
    operation of real estate.

  . Until the properties of the Partnership are sold and the Partnership is
    liquidated and terminated, limited partners would continue to receive
    Schedule K-1s from the Partnership, and the Partnership would continue to
    have SEC and tax reporting obligations.

 (1) Based upon balance sheets as of March 31, 1999, and includes impact of
     the general partner's deficit restoration obligation, if any, to the
     McNeil Partnership, as estimated by Arthur Andersen LLP as of March 31,
     1999. Arthur Andersen LLP's estimates were based, in part, on limited
     historical tax records prepared by other accounting firms. Sufficient
     records did not exist such that Arthur Andersen LLP could test the
     accuracy of prior accountants' work. Further, these estimates were based
     on the McNeil Partnerships' projections of 1999 operating results through
     March 31, 1999 and on hypothetical asset sale/partnership liquidation
     information provided by Stanger & Co. Arthur Andersen LLP has not audited
     or opined on the projected results of operations or financial information
     relating to such hypothetical sales/liquidations.
 (2) Amount includes per unit merger consideration and estimated per unit
     special distribution. See Table 2.
 (3) Stanger & Co. estimated the "Net Asset Value" per limited partner unit in
     each McNeil Partnership as follows:
   (a) Stanger & Co.'s estimate of the value of the real estate assets of the
       McNeil Partnership net of the mark-to-market adjustment on the mortgage
       debt of that McNeil Partnership, as described in "--Reports and opinions
       of financial advisors--Allocation analysis and opinions of Stanger &
       Co.--Financial analysis of Stanger & Co.;"

   (b) Plus: the book value of the other tangible assets of the McNeil
       Partnership as of March 31, 1999;
   (c) Plus: the deficit restoration obligation, if any, of the general partner
       of the McNeil Partnership, as estimated by Arthur Andersen LLP as of
       March 31, 1999, assuming the McNeil Partnership had been liquidated on
       that date. Arthur Andersen LLP's estimates were based, in part, on
       limited historical tax records prepared by other accounting firms.
       Sufficient records did not exist such that Arthur Andersen LLP could
       test the accuracy of prior accountants' work. Further, these estimates
       were based on the McNeil Partnerships' projections of 1999 operating
       results through March 31, 1999 and on hypothetical asset
       sale/partnership liquidation information provided by Stanger & Co.
       Arthur Andersen LLP has not audited or opined on the projected results
       of operations or financial information relating to such hypothetical
       sales/liquidations.
   (d) Less: the mortgage debt outstanding as of March 31, 1999;
   (e) Less: other liabilities of the McNeil Partnership outstanding as of
       March 31, 1999, including amounts recorded as liabilities to the general
       partner of the McNeil Partnership and its affiliates, including McREMI;
       and
   (f) Less: the transaction expenses as estimated by McNeil Partners.
  The resulting net asset value was divided by the number of limited partner
  units in the McNeil Partnership outstanding as of March 31, 1999 to derive
  the "Net Asset Value" per limited partner unit.
 (4) Stanger & Co. estimated the "Going Concern Value" per limited partner
     unit in each McNeil Partnership based upon the continued operation of the
     McNeil Partnership for a ten-year period. Real estate cash flows and the
     residual value of the real estate at the end of ten years were estimated
     by Stanger & Co. Debt service was estimated based on the terms of the
     existing mortgages in place. Stanger & Co. assumed the existing mortgages
     were refinanced at the earlier of: (a) the expiration of the term of the
     mortgage; (b) the date on which any prepayment penalty was eliminated;
     and (c) the date on which any prepayment penalty, plus the outstanding
     mortgage balance, is less than the present value, discounted at 7.5%, of
     the remaining obligations due under the mortgage. The mortgage balance
     and any prepayment penalties were assumed refinanced at 7.5% per annum
     interest with an amortization period of 30 years. Administrative fees and
     expenses were based upon normalized 1997 and 1998 expense levels. Asset
     management fees were estimated in accordance with the limited partnership
     agreement of the McNeil Partnership. Net cash flows calculated pursuant
     to the going concern analysis were discounted to present value at a
     premium to the estimated internal rate of return for the real estate
     portfolio based upon several factors including illiquidity and leverage,
     as estimated by Stanger & Co. The resulting going concern value was
     divided by the number of limited partner units outstanding as of March
     31, 1999 to derive the "Going Concern Value" per limited partner unit.
 (5) Stanger & Co. estimated the "Liquidation Value" per limited partner unit
     based upon the "Net Asset Value" of the McNeil Partnership, adjusted for
     additional costs, estimated at 2.5% of real estate value, associated with
     the sale of the assets, continued operation of the McNeil Partnership and
     the wind-down of partnership operations.
 (6) Per database of Stanger & Co. through March 31, 1999, except as noted.
 (7) As reported by McREMI. See "Related Security Holder Matters--Past
     contacts, transactions and negotiations."
 (8) McNeil Summerhill I, L.P. is more than 95% leveraged and therefore "Going
     Concern Value" is deemed inapplicable.

Effects of the transaction

   The Master Agreement provides that WXI/McN Realty will acquire the general
partner interests and limited partner interests in each of the McNeil
Partnerships, assets of McNeil Partners related to the McNeil Partnerships and
certain assets of McREMI. Each McNeil Partnership's participation in the
transaction is subject to the requisite approval of its limited partners.

 Effects of the transaction on the Partnership

   If the merger proposal is approved by the limited partners of the
Partnership and the Partnership participates in the transaction, then the
effects of the transaction with respect to the Partnership will be as follows:

  . WXI/McN Realty will acquire all of the general partner interests and
    limited partner interests in the Partnership, assets of McNeil Partners
    related to the Partnership and assets of McREMI related to the
    Partnership.

  . As a result of the transaction, the Partnership will become a directly
    and/or indirectly wholly owned subsidiary of WXI/McN Realty. WXI/McN
    Realty or a wholly owned subsidiary of WXI/McN Realty will be the sole
    limited partner of the Partnership, and a separate directly or indirectly
    wholly owned subsidiary of WXI/McN Realty will be the general partner of
    the Partnership. A separate directly or indirectly wholly owned
    subsidiary of WXI/McN Realty will own and operate the assets of McREMI.

  . Following the completion of the transaction, the current limited partners
    of the Partnership will no longer have any interest in and will not be
    limited partners of the Partnership and, therefore, will not participate
    in the Partnership's future earnings and potential growth.

  . Following the completion of the transaction with respect to the
    Partnership, the limited partner units in the Partnership will cease to
    be registered under the Securities Exchange Act, all tax return and SEC
    reporting obligations of the Partnership will cease and limited partners
    of the Partnership will no longer receive Schedule K-1s from the
    Partnership.

  . Limited partners of the Partnership will receive approximately [For all
    except Funds XXI-XXIII: $    in cash for each limited partner unit.] [for
    Funds XXI-XXIII: $    in cash for each current income unit and $    in
    cash for each growth/shelter unit.] [For all except Funds XXI-XXIII: The
    amount for each limited partner unit consists of merger consideration of
    $    per unit and a special cash distribution estimated as of    , 1999
    at $    per unit.] [For Funds XXI-XXIII: The amount for each current
    income unit consists of merger consideration of $    per unit and a
    special cash distribution estimated as of    , 1999 at $    per unit. The
    amount for each growth/shelter unit consists of merger consideration of
    $    per unit and a special cash distribution estimated as of    , 1999
    at $    per unit.]

  . The merger consideration is equal to the amount of the aggregate
    consideration in the transaction allocated by Stanger & Co. to each of
    the limited partner units in the Partnership. If the Partnership
    participates in the transaction, each limited partner unit will be
    converted at the effective time of the merger of the Partnership into the
    right to receive the per unit merger consideration.

  . In addition, if the Partnership has a positive net working capital
    balance, limited partners in the Partnership will receive their pro rata
    share of a special distribution of the positive net working capital
    balance. The net working capital balance of the Partnership will be
    calculated in accordance with the Master Agreement and will be based on a
    modified net working capital balance of the Partnership estimated as of
    the closing date. This special distribution will be made in accordance
    with the provisions of the Partnership's limited partnership agreement
    governing distributions of surplus cash, except that the general partner
    of that McNeil Partnership will not receive any part of the special
    distribution.

  . McNeil Partners will receive membership interests in and credit for a
    capital contribution to WXI/McN Realty in exchange for its contributions
    to WXI/McN Realty and WXI/McN Realty's subsidiaries of its

                                       75
<PAGE>

   general partner interests in the Partnership, assets of McNeil Partners
   related to the Partnership and assets of McREMI related to the
   Partnership. The amount of this capital contribution will be equal to
   $   , the amount of the aggregate consideration allocated by Stanger & Co.
   to these contributions. See "--Opinions and reports of financial
   advisors--Allocation analysis and opinions of Stanger & Co.--Stanger & Co.
   allocation analysis."

  . McNeil Partners also may contribute cash to WXI/McN Realty under some
    circumstances and will have the right to treat some fees, expenses and
    disbursements incurred by the McNeil Affiliates in connection with the
    transaction as a contribution in-kind to WXI/McN Realty. In consideration
    for that cash contribution and that contribution in-kind, McNeil Partners
    will receive additional membership interests in WXI/McN Realty and credit
    for capital contribution to WXI/McN Realty in the amount of that cash
    contribution and that contribution in-kind to WXI/McN Realty. See "--
    Interests of certain persons in the matters to be acted upon; conflicts
    of interest--Equity interest of McNeil Partners in WXI/McN Realty."

 Effects of the transaction on all of the other participating McNeil
 Partnerships and the McNeil Affiliates

  . For each other participating McNeil Partnership, other than the
    Affiliated McNeil Partnerships, the effects of the transaction with
    respect to that participating McNeil Partnership will be the same as the
    effects described above with respect to the Partnership. The merger
    consideration and estimated special distribution per limited partner unit
    in each of the McNeil Partnerships is set forth in Table 2 in the columns
    "Per Unit Merger Consideration" and "Per Unit Special Distribution." The
    amount of the capital contribution by McNeil Partners to WXI/McN Realty
    in exchange for its contributions to WXI/McN Realty and WXI/McN Realty's
    subsidiaries of its general partner interests in each participating
    McNeil Partnership, certain assets of McNeil Partners related to that
    McNeil Partnership and certain assets of McREMI related to that McNeil
    Partnership is set forth in Table 2 in the column entitled "MPLP
    Allocation Amount."

  . McNeil Partners also will receive membership interests in and credit for
    a capital contribution to WXI/McN Realty in exchange for its
    contributions to WXI/McN Realty and WXI/McN Realty's subsidiaries of the
    limited partner interests in the Affiliated McNeil Partnership and assets
    of McREMI. The amount of this capital contribution will be equal to the
    aggregate consideration allocated by Stanger & Co. to these
    contributions.

  . If all of the McNeil Partnerships are participating McNeil Partnerships,
    the portion of the aggregate consideration to be received by McNeil
    Partners in the form of membership interests and credit for a capital
    contribution in exchange for the contributions described in the
    immediately preceding two bullet points will equal approximately $   .
    See "--Interests of certain persons in the matters to be acted upon;
    conflicts of interest--Equity interest of McNeil Partners in WXI/McN
    Realty."

 Benefits and detriments of the transaction to the McNeil Affiliates

   The primary benefits of the transaction to the McNeil Affiliates are the
following:

  . The transaction satisfies McNeil Partners' obligations under the limited
    partnership agreements of the public McNeil Partnerships to use
    commercially reasonable efforts to complete the liquidation and
    termination of the public McNeil Partnerships by December 31, 1999. See
    "--Background of the transaction--Restructuring of the public McNeil
    Partnerships" and "--Background of the transaction--Icahn tender offers."

  . The Stipulation of Settlement of the Schofield litigation also provided a
    commitment of McNeil Partners to market the McNeil Partnerships for sale,
    together with McREMI, through a fair and impartial bidding process
    overseen by a national investment banking firm. See "--Background of the
    transaction--Background of the Schofield litigation." The settlement was
    not conditioned on the consummation of the transaction described in this
    Proxy Statement.

                                       76

  . McNeil Partners will receive a portion of the aggregate consideration
    equal to $      in consideration of some of its contributions to WXI/McN
    Realty Company. This portion of the aggregate consideration will be paid
    to McNeil Partners in the form of membership interests in and credit for
    a capital contribution to WXI/McN Realty in exchange for its contribution
    to WXI/McN Realty and its subsidiaries of the following: (1) its general
    partner interests in each of the participating McNeil Partnerships, (2)
    the limited partner units in the Affiliated McNeil Partnerships, (3)
    certain assets of McNeil Partners related to the participating McNeil
    Partnerships and (4) certain assets of McREMI. The amount of this capital
    contribution will be equal to the aggregate consideration allocated by
    Stanger & Co. to these contributions. See the "Total Allocated McNeil
    Value" set forth in Table 2 . See "--Opinions and reports of financial
    advisors--Allocation Analysis and opinions of Stanger & Co.--Stanger &
    Co. allocation analysis" and "--Interests of certain persons in matters
    to be acted upon; conflicts of interest--Equity interest of McNeil
    Partners in WXI/McN Realty."

  . McNeil Partners and its affiliates also will receive a portion of the
    aggregate consideration for the limited partner units that they own in
    the McNeil Partnerships. McNeil Partners and these affiliates will
    receive the same cash consideration for each of their limited partner
    units in the participating McNeil Partnerships, other than the Affiliated
    McNeil Partnerships, as the other limited partners of that McNeil
    Partnership. If all of the McNeil Partnerships, other than the Affiliated
    McNeil Partnerships, in which McNeil Partners and these affiliates own
    limited partner units are participating McNeil Partnerships, McNeil
    Partners and these affiliates will receive aggregate cash consideration
    of approximately $      . This figure is the sum of the per unit merger
    consideration and estimated per unit special distribution for those
    McNeil Partnerships. As described in the second bullet point above,
    McNeil Partners will receive membership interests in WXI/McN Realty in
    consideration for its contribution to WXI/McN Realty and WXI/McN Realty's
    subsidiaries of its limited partner units in the Affiliated McNeil
    Partnerships.

  . McNeil Partners also may contribute cash to WXI/McN Realty under certain
    circumstances and will receive equity interests in WXI/McN Realty and
    credit for a capital contribution to WXI/McN Realty in the amount of any
    cash contributed. McNeil Partners also has the right to treat some fees,
    expenses and disbursements incurred by the McNeil Affiliates in
    connection with the transaction as a contribution in-kind to WXI/McN
    Realty. McNeil Partners will receive equity interests in WXI/McN Realty
    and credit for capital contribution to WXI/McN Realty in the amount of
    that contribution in-kind. See "--Interests of certain persons in matters
    to be acted upon; conflicts of interest--Equity interest of McNeil
    Partners in WXI/McN Realty."

  . It is anticipated that immediately following the effective time of the
    mergers, McNeil Partners will own in the aggregate between approximately
     % and  % of the then outstanding membership interests in WXI/McN Realty,
    depending on the amount of financing obtained by WXI/McN Realty as of the
    closing and the amount of the capital contributions of McNeil Partners to
    WXI/McN Realty. The other McNeil Affiliates will indirectly beneficially
    own an equity interest in WXI/McN Realty following the effective time of
    the mergers as a result of their ownership of partnership interests in
    McNeil Partners. See "The Master Agreement--The contributions--
    Contributions to McNeil Partners by the other McNeil Affiliates."

  . The membership interests received by McNeil Partners in WXI/McN Realty
    will entitle McNeil Partners to receive a specified percentage return on
    its investment in WXI/McN Realty and to receive distributions of WXI/McN
    Realty's net cash flow and net proceeds from capital transactions in the
    priority set forth in the WXI/McN Realty Operating Agreement.
    Consequently, McNeil Partners and the other McNeil Affiliates, through
    their ownership of partnership interests in McNeil Partners, will have a
    significant interest in WXI/McN Realty and will continue to have the
    opportunity to participate in any future earnings growth and to benefit
    from any increases in the value of the participating McNeil Partnerships
    and their properties, the McREMI assets and any other assets acquired by
    WXI/McN Realty and its subsidiaries. This return will be equal to 14% or
    15% per annum depending on McNeil Partners' initial capital contribution
    to WXI/McN Realty. Following the effective time of the mergers,

                                       77
<PAGE>

   McNeil Partners and WXI/McN Realty's managing member will be the sole
   members of WXI/McN Realty.

  . Under the terms of the WXI/McN Realty Operating Agreement, following the
    effective time of the mergers, McNeil Partners also will have the right
    to designate two of the five members of WXI/McN Realty's board of
    managers. The remaining three members will be designated by WXI/McN
    Realty's managing member. Action by WXI/McN Realty's board of managers
    will require the affirmative vote of three of the five managers. However,
    some actions of WXI/McN Realty's board of managers will require a super-
    majority vote of four of the five managers. Therefore, McNeil Partners
    will have a right to veto any transactions that require a supermajority
    vote of WXI/McN Realty's board of managers. See "WXI/McN Realty Operating
    Agreement."

  . WXI/McN Realty will repay or indirectly assume all outstanding mortgage
    debt of each of the participating McNeil Partnerships. McNeil Partners
    and McNeil Investors currently are parties to existing indemnification
    obligations or agreements relating to mortgage debt on some of the McNeil
    Partnership properties and agreements with lenders or affiliates of
    lenders of some mortgage debt on some of the properties. Under these
    existing indemnification obligations and agreements, McNeil Partners or
    McNeil Investors or both have assumed liability on behalf of one or more
    McNeil Partnerships or their subsidiaries for exceptions to non-recourse
    provisions contained in that mortgage debt. In the Master Agreement,
    WXI/McN Realty has agreed to deliver at the closing of the transaction
    any replacement agreements and documents necessary to assume all of the
    obligations of Sellers (other than the participating McNeil Partnerships)
    and their affiliates as indemnitor under all of those existing
    indemnification obligations or agreements, and to use its reasonable
    efforts to ensure that those replacement agreements and documents
    delivered at the closing release Sellers (other than the participating
    McNeil Partnerships) and their affiliates from all of Sellers' (other
    than the participating McNeil Partnerships) and their affiliates'
    obligations under those existing indemnification obligations and
    agreements. See "The Master Agreement--Replacement indemnification
    agreements."

  . The Master Agreement provides that if McNeil Summerhill I, L.P. is a
    participating McNeil Partnership, WXI/McN Realty will contribute adequate
    cash to McNeil Summerhill I, L.P. to, and will cause McNeil Summerhill I,
    L.P. to, repay at the effective time of the mergers the demand note,
    dated November 17, 1997, payable by McNeil Summerhill I, L.P. to Robert
    A. McNeil and Carole J. McNeil, together with all accrued but unpaid
    interest to the effective time on the demand note. See "--Interests of
    certain persons in matters to be acted upon; conflicts of interest." As
    of the date of this Proxy Statement, the outstanding principal balance of
    this demand note is $    , and the accrued and unpaid interest on the
    demand note is $    . However, the modified net working capital balance
    of McNeil Summerhill I, L.P. for purposes of determining the special
    distribution for McNeil Summerhill I, L.P. will be calculated as if the
    demand note was not repaid and WXI/McN Realty had not contributed cash to
    McNeil Summerhill I, L.P. See "The Master Agreement--The mergers--Special
    distribution of positive net working capital balance."

  . The transaction, as structured, will allow McNeil Partners to transfer
    its general partner interests in the McNeil Partnerships, its limited
    partner units in the Affiliated McNeil Partnerships, assets of McNeil
    Partners and assets of McREMI to WXI/McN Realty and WXI/McN Realty's
    subsidiaries in exchange for membership interests in WXI/McN Realty on a
    tax-free basis and to defer substantial income tax liability that would
    be incurred if there had been a taxable sale of the properties. A taxable
    sale of the properties would produce taxable gain in excess of the cash
    proceeds because of the relief of partnership liabilities allocated to
    them. See "--Federal income tax consequences--Tax consequences to McNeil
    Partners."

   The primary detriments of the transaction to the McNeil Affiliates are the
following:

  . McNeil Partners has agreed to irrevocably, unconditionally and absolutely
    waive any and all rights it may have to indemnification, contribution or
    reimbursement from any of the participating McNeil Partnerships, whether
    under the limited partnership agreement, any contractual arrangement,
    applicable

                                       78
<PAGE>

   law or otherwise, with respect to those matters for which McNeil Partners
   has agreed to indemnify WXI/McN Realty's managing member and some of its
   affiliates.

  . McNeil Partners and Robert A. McNeil have agreed to indemnify WXI/McN
    Realty's managing member and some of its affiliates for all actual and
    out-of-pocket costs, expenses, judgments, fines, losses, claims, damages
    and liabilities arising from certain matters described in "Other
    Agreements Between the McNeil Affiliates and Affiliates of WXI/McN
    Realty--Indemnification and pledge agreement."

  . In allocating the aggregate consideration, Stanger & Co. took the
    position that the deficit restoration obligations of the general partners
    of the McNeil Partnerships were required to be paid to the McNeil
    Partnerships. As a result, the aggregate consideration allocated by
    Stanger & Co. to the general partner interests in each of the McNeil
    Partnerships is net of the deficit restoration obligation with respect to
    that McNeil Partnership. The aggregate amount of the deficit restoration
    obligations payable in respect of all of the McNeil Partnerships,
    estimated by Arthur Andersen LLP, based upon a hypothetical sale of the
    properties and liquidation of the McNeil Partnerships at March 31, 1999,
    is approximately $6,439,000. The estimated deficit restoration obligation
    payable in respect of the Partnership, estimated by Arthur Andersen LLP,
    based upon a hypothetical sale of the properties and liquidation of the
    McNeil Partnerships at March 31, 1999, is $    . Arthur Andersen LLP's
    estimates were based, in part, on limited historical tax records prepared
    by other accounting firms. Sufficient records did not exist such that
    Arthur Andersen LLP could test the accuracy of prior accountants' work.
    Further, these estimates were based on the McNeil Partnerships'
    projections of 1999 operating results through March 31, 1999 and on
    hypothetical asset sale/partnership liquidation information provided by
    Stanger & Co. Arthur Andersen LLP has not audited or opined on the
    projected results of operations or financial information relating to such
    hypothetical sales/liquidations. See "--Opinions and reports of financial
    advisors--Allocation analysis and opinions of Stanger & Co.--Stanger &
    Co. allocation analysis."

  . In allocating the aggregate consideration, Stanger & Co. has assumed that
    no asset disposition fee is payable by any of the McNeil Partnerships to
    the McNeil General Partners. In a liquidation, the limited partnership
    agreements of some of the McNeil Partnerships provide that McNeil
    Partners would be entitled to receive an asset disposition fee equal to
    3% of the gross sales price of each property sold by that McNeil
    Partnership. No asset disposition fees will be paid by any of the McNeil
    Partnerships as a result of the transaction.

  . The McNeil General Partners will cease to be the general partners of the
    participating McNeil Partnerships following the transaction. As a result,
    the McNeil General Partners will no longer be entitled to any of the
    rights and benefits of a general partner of the participating McNeil
    Partnerships, including the right to receive fees and other distributions
    from the participating McNeil Partnerships under the limited partnership
    agreements of the participating McNeil Partnerships.

  . The McNeil Affiliates will no longer be in control of the participating
    McNeil Partnerships and the assets of McREMI following the transaction.
    See "--Interests of certain persons in matters to be acted upon;
    conflicts of interest--Relationships among the McNeil Affiliates and the
    McNeil Partnerships." Although McNeil Partners will own membership
    interests in WXI/McN Realty following the effective time of the
    transaction, McNeil Partners will not be in control of WXI/McN Realty.
    McNeil Partners will have the right to designate only two of the five
    members of WXI/McN Realty's board of managers. The remaining three
    members of WXI/McN Realty's board of managers will be designated by
    WXI/McN Realty's managing member. Except in some limited circumstances in
    which the vote of four of five of the managers is required, decisions of
    WXI/McN Realty's board of managers require a vote of only three of the
    five members. Therefore, action generally may be taken by WXI/McN
    Realty's board of managers without the approval of McNeil Partners. See
    "WXI/McN Realty Operating Agreement."

  . The opportunity of the McNeil Affiliates to participate in any future
    earnings growth of WXI/McN Realty is limited to the percentage return on
    investment to which they are entitled under the WXI/McN Realty Operating
    Agreement. This percentage return is limited to 14% or 15%, depending on
    McNeil

                                       79

   Partners' initial capital contribution to WXI/McN Realty. See "WXI/McN
   Realty Operating Agreement."

Opinions and reports of financial advisors

 Allocation analysis and opinions of Stanger & Co.

   Each of the McNeil Partnerships engaged Stanger & Co. as its independent
advisor on January 12, 1998. Stanger & Co. was engaged based on its experience
and expertise. Stanger & Co., founded in 1978, has provided information,
research, investment banking and consulting services to clients throughout the
United States, including major New York Stock Exchange, Inc. firms and
insurance companies and over 70 companies engaged in the management and
operation of partnerships and REITs. The investment banking activities of
Stanger & Co. include financial advisory services, asset and securities
valuations, industry and company research and analysis, litigation support and
expert witness services, and due diligence investigations in connection with
both publicly registered and privately placed securities transactions.

  First Stanger & Co. opinion

   At the June 24, 1999 meeting of the McNeil Investors board of directors,
Stanger & Co. delivered its allocation analysis of the aggregate consideration
described below in "--Opinions and reports of financial advisors--Allocation
analysis and opinions of Stanger & Co.--Stanger & Co. allocation analysis" and
a written opinion of fairness to the effect that as of the date of the opinion,
and subject to the assumptions, qualifications and limitations set forth in the
opinion, each of the five matters set forth below was fair from a financial
point of view to the holders of each class of limited partner units in each of
the McNeil Partnerships:

  . the aggregate consideration in the transaction;

  . the allocation of the aggregate consideration between the management
    assets of McREMI, on the one hand, and the McNeil Partnerships as a
    group, on the other hand;

  . the aggregate consideration allocated to each individual McNeil
    Partnership;

  . the methodology of allocation of the aggregate consideration allocated to
    each individual McNeil Partnership, less the principal amount of all
    outstanding mortgage debt of that McNeil Partnership, among the general
    partner interests in that McNeil Partnership, the other assets of McREMI
    related to that McNeil Partnership and each class of limited partner
    units in that McNeil Partnership; and

  . the estimated amount of the positive net working capital balance
    estimated to be distributed per limited partner unit in each McNeil
    Partnership and the amount of the aggregate consideration allocated to
    each limited partner unit in each McNeil Partnership, determined as of
    March 31, 1999, based upon the balance sheet of each McNeil Partnership
    as of March 31, 1999, adjusted for transaction expenses and the
    allocation of transaction expenses, as estimated by the McNeil General
    Partners.

   The written fairness opinion delivered by Stanger & Co. to the McNeil
Investors board of directors on behalf of the McNeil Partnerships on June 24,
1999 is referred to in this Proxy Statement as the "first Stanger & Co.
opinion." In making the determinations described in "--Recommendations of the
special committee and the McNeil Investors board of directors; fairness of the
transaction--Recommendations of the McNeil Investors board of directors" and in
approving the merger proposal, the McNeil Investors board of directors relied
on, among other things, the Stanger & Co. allocation analysis and the first
Stanger & Co. opinion.

   The full text of the first Stanger & Co. opinion, which sets forth the
assumptions made, matters considered and qualifications and limitations on the
review undertaken by Stanger & Co., is incorporated in this Proxy Statement by
reference. The first Stanger & Co. opinion is attached as Appendix C-1 to this
Proxy Statement. The limited partners of the Partnership are urged to read
carefully the first Stanger & Co. opinion in its entirety.

  Second Stanger & Co. opinion

   On      , 1999, Stanger & Co. delivered a second written opinion to the
McNeil Investors board of directors on behalf of the McNeil Partnerships. In
this second opinion, Stanger & Co. rendered additional opinions as to the
fairness from a financial point of view to the holders of each class of limited
partner units in each of the McNeil Partnerships as to the allocation of the
consideration described in the fourth bullet point in "--Opinions and reports
of financial advisors--Allocation analysis and opinions of Stanger & Co.--First
Stanger & Co. opinion." The second opinion delivered by Stanger & Co. on      ,
1999 is referred to in this Proxy Statement as the "second Stanger & Co.
opinion." The second Stanger & Co. opinion is described in more detail below.

   The full text of the second Stanger & Co. opinion, which sets forth the
assumptions made, matters considered and qualifications and limitations on the
review undertaken by Stanger & Co., is incorporated in this Proxy Statement by
reference. The second Stanger & Co. opinion is attached as Appendix C-2 to this
Proxy Statement. The limited partners of the Partnership are urged to read
carefully the second Stanger & Co. opinion in its entirety.

   The second Stanger & Co. opinion was to the effect that, as of the date of
the second Stanger & Co. opinion, and subject to the assumptions,
qualifications and limitations set forth in the second Stanger & Co. opinion,
each of the matters set forth below was fair from a financial point of view to
the holders of each class of limited partner units in each of the McNeil
Partnerships:

  . the aggregate consideration allocated to the general partner interests in
    each McNeil Partnership (see "GP Allocation Amount" in Table 2);

  . the aggregate consideration allocated to the other assets of McREMI
    related to each McNeil Partnership (see "Second McREMI Allocated Value"
    in Table 2);

  . the aggregate consideration allocated to each class of limited partner
    units in each McNeil Partnership (see "LP Allocation Amount" in Table 2);
    and

  . the estimated amount of the aggregate consideration allocated to each
    limited partner unit in each McNeil Partnership (see "Per Unit Merger
    Consideration" in Table 2) and the dollar amount of the positive net
    working capital balance estimated to be distributed per limited partner
    unit in each McNeil Partnership, determined as of      , 1999, based upon
    the balance sheet of each McNeil Partnership as of      , 1999, adjusted
    for transaction expenses and the allocation of transaction expenses, as
    estimated by the McNeil General Partners (see "Estimated Per Unit Special
    Distribution" in Table 2). See "Total Per Unit Estimate" in Table 2.

   In considering the opinions described above, limited partners of the
Partnership should be aware that each of the Stanger opinions:

  . was provided to the McNeil Partnerships for their information and is
    directed only to the fairness, from a financial point of view, to the
    holders of each class of limited partner units in each McNeil
    Partnership;

  . did not constitute a recommendation to the McNeil Partnerships or the
    McNeil General Partners in connection with the transactions;

  . did not address the merits of the underlying decision by McNeil
    Partnerships or the General Partners to engage in the transactions or the
    price or range of prices at which each class of limited partner units in
    each McNeil Partnership may trade subsequent to the announcement or
    consummation of the transactions; and

  . does not constitute a recommendation to any limited partner of any McNeil
    Partnership as to how that limited partner should vote on the merger
    proposal, or any matter related to the merger proposal.


                                       81
<PAGE>

   Although Stanger & Co. evaluated the fairness, from a financial point of
view, of the aggregate consideration and the allocation of the aggregate
consideration in the transaction to the holders of limited partner units in
each McNeil Partnership, the terms were determined through arm's-length
negotiations among McNeil management, the special committee, WXI/McN Realty and
their respective representatives. Stanger & Co. provided advice to the McNeil
Partnerships during the course of those negotiations. The McNeil Partnerships
did not provide specific instructions to, or place any limitations on, Stanger
& Co. with respect to the procedures to be followed or factors to be considered
by it in performing its analyses or providing its opinions.

   In arriving at the opinions described above, Stanger & Co., among other
things:

  . reviewed the Master Agreement and the WXI/McN Realty Operating Agreement;

  . reviewed, in the case of the second Stanger opinion, the latest draft of
    this Proxy Statement made available to it;

  . reviewed the financial statements of each McNeil Partnership for the
    years ended December 31, 1997 and 1998, the three months ended March 31,
    1999 and the     months ended    , 1999;

  . reviewed information provided by McREMI, as property manager, the McNeil
    General Partners and each McNeil Partnership for each property owned by
    that McNeil Partnership, including: property description, rentable square
    footage, unit mix, year built, historical and projected operating
    statements, rent rolls, tenant improvement allowances, expense
    reimbursements, tax information, capital expenditure estimates, deferred
    maintenance estimates, and estimates of costs to remediate environmental
    conditions;

  . conducted site inspections of each property and discussed with management
    of McREMI, the McNeil General Partners and the McNeil Partnerships the
    conditions in local rental markets and market conditions for sales and
    acquisitions of properties of the type owned by each McNeil Partnership
    and the historical financial statements and budgeted and projected
    operations of the properties;

  . reviewed surveys of competing properties prepared by or on behalf of
    McREMI, the McNeil General Partners and the McNeil Partnerships,
    including rental rates, vacancies, and tenant improvement allowances;

  . reviewed information on acquisition criteria used by real estate
    investors for properties similar to the McNeil Partnerships' properties
    during 1999;

  . reviewed the financial statements of McREMI and its affiliates for the
    years ended December 31, 1997 and 1998, the three months ended March 31,
    1999 and the   months ended     , 1999;

  . interviewed PaineWebber regarding the bid solicitation process relating
    to the transaction; and

  . conducted such other studies, analyses, inquiries and investigations as
    it deemed appropriate.

   In rendering the Stanger & Co. opinions, Stanger & Co. relied, without
independent verification, on the accuracy and completeness in all material
respects of all financial and other information that was furnished or otherwise
communicated to Stanger & Co. by McREMI, the McNeil General Partners and the
McNeil Partnerships. Stanger & Co. did not perform an independent appraisal of
the assets and liabilities of the McNeil Partnerships or the McREMI assets.
Stanger & Co. did not conduct any engineering studies and relied on the
estimates of the management of McREMI with respect to deferred maintenance and
the estimated cost to remediate environmental conditions for each property.

   Stanger & Co. relied on the assurance of McREMI, the General Partners and
the McNeil Partnerships, that:

  . the property budgets and discounted cash flow analyses provided to
    Stanger & Co. were in the judgment of McREMI, the General Partners and
    the McNeil Partnerships reasonably prepared on bases consistent

                                       82
<PAGE>

   with actual historical experience and reflect the best currently available
   estimates and good faith judgments;

  . any estimates of costs to remediate environmental conditions were
    adequately considered in the capital expenditure estimates provided to
    Stanger & Co. and that no additional environmental conditions were
    present at the McNeil Partnerships' properties;

  . any historical financial data, balance sheet data, transaction cost
    estimates and estimates of the deficit restoration obligation of the
    McNeil General Partners which would be due upon a liquidation were
    accurate in all material respects;

  . no material changes have occurred in the information reviewed or in the
    value of the McNeil Partnerships' properties or the McREMI assets between
    the date the information was provided to Stanger & Co. and the date of
    its opinion; and

  . McREMI, the McNeil General Partners and the McNeil Partnerships were not
    aware of any information or facts regarding the McNeil Partnerships, the
    McNeil Partnerships' properties, the McREMI assets or WXI/McN Realty that
    would cause the information supplied to Stanger & Co. to be incomplete or
    misleading in any material respect.

   Stanger & Co. did not determine or negotiate the amount or form of the
aggregate consideration in the transaction. Stanger & Co. was not requested to,
and therefore did not, make any recommendation to McREMI, the McNeil General
Partners or the limited partners of any of the McNeil Partnerships with respect
to whether to approve or reject the transactions or express any opinion as to:

  . the impact of the transactions with respect to McREMI, the McNeil General
    Partners or the limited partners of any McNeil Partnership that does not
    participate in the transaction;

  . the tax consequences of the transactions for McREMI, the McNeil General
    Partners or the limited partners of any McNeil Partnership;

  . WXI/McN Realty's ability to qualify as a partnership or real estate
    investment trust, or the consequences of WXI/McN Realty's failure to so
    qualify;

  . the potential capital structure of WXI/McN Realty or its impact on the
    financial performance of WXI/McN Realty's membership interests;

  . WXI/McN Realty's ability to finance its obligations pursuant to the
    Master Agreement or the impact of a failure to obtain financing on the
    financial performance of WXI/McN Realty or the McNeil Partnerships;

  . whether or not alternative methods of determining or allocating the
    aggregate consideration to be received by any of the McNeil Affiliates or
    the limited partners of any of the McNeil Partnerships would have also
    provided fair results or results substantially similar to those of the
    methodology to be used;

  . alternatives to the transaction; or

  . any other terms of the transaction other than the aggregate consideration
    and the allocation of the aggregate consideration.

   Stanger & Co. did not express any opinion to Robert A. McNeil or Carole J.
McNeil in their capacities as direct or indirect holders of general partner
interests or limited partner units in the McNeil Partnerships or in McNeil
Partners or of capital stock in McREMI. Furthermore, Stanger & Co. did not
express any opinion as to the fairness of any terms of the transaction other
than as described in the Stanger opinions, including without limitation the
fairness of the amounts or allocations of transaction costs, or the prices at
which the membership interests in WXI/McN Realty may trade, if the membership
interests were traded, following the transaction, or the trading value of the
membership interests in WXI/McN Realty compared with the current fair market
value

if WXI/McN Realty were to be liquidated in the current real estate market.

   The foregoing description does not purport to be a complete description of
the analyses performed or the matters considered in rendering the Stanger
opinions. The analyses and the summary set forth in the Stanger opinions must
be considered as a whole, and selecting portions of such summary or analyses,
without considering all factors and analyses, would create an incomplete view
of the processes underlying the Stanger & Co. opinions. In rendering the
Stanger opinions, judgment was applied to a variety of complex analyses and
assumptions. The assumptions made and the judgments applied in rendering the
Stanger opinions are not readily susceptible to partial analysis or summary
description. The fact that any specific analysis is referred to in the Stanger
opinions or in this Proxy Statement is not meant to indicate that such analysis
was given greater weight than any other analysis.

  Financial analysis of Stanger & Co.

   Stanger & Co.'s financial analysis began with an estimate of the real estate
values of each of the McNeil Partnerships. To determine the value of the real
estate of each McNeil Partnership, Stanger & Co. performed a property level
review, a balance sheet review, a partnership agreement review and a bid
solicitation review, each described more fully below.

   Property Level Review. Stanger & Co. performed a site inspection of each
property. In the course of the site visit, the physical facilities of each
property were observed, rental and occupancy information was obtained, local
market conditions were reviewed, similar competing properties were identified,
and local property management personnel were interviewed concerning the
property and local market conditions. Stanger & Co. also reviewed and relied
upon information provided by each McNeil Partnership and its agents including,
but not limited to, financial schedules of historical and current rental rates,
occupancy, income, expenses, reserve requirements, and related financial
information, property descriptive information including unit mix or square
footage, deferred maintenance estimates, capital budgets, and other factors
affecting the physical condition of the properties.

   For each property, Stanger & Co. estimated net operating income for 1999
based upon the above review as well as a review of actual net operating income
for such property for 1995, 1996, 1997 and 1998 and the three months ended
March 31, 1999 and the 1999 budget prepared by McREMI management.

   Stanger & Co. estimated the value of each property using the income approach
to valuation. For apartment and self-storage properties, Stanger & Co. relied
primarily on the direct capitalization method of the income approach. In the
direct capitalization method of the income approach, net operating income is
capitalized at a capitalization rate to derive value. The capitalization rate
used for each property was based upon Stanger & Co.'s review of: (1) published
survey data by Korpacz & Associates, Real Estate Research Corporation, Cushman
& Wakefield and National Real Estate Index; and (2) data collected by Stanger &
Co. from local market inquiries. For office and retail properties, Stanger &
Co. relied primarily on the discounted cash flow method of the income approach.
In the discounted cash flow method of the income approach, a ten-year cash flow
projection was made based upon leases in place and various assumptions
regarding renewals of such leases over a ten year period. A residual value for
the property was based upon year eleven net operating income capitalized at a
terminal capitalization rate and reduced by selling expenses. The cash flow for
the ten-year period and the residual value were discounted to present value at
a discount rate. The terminal capitalization rate and discount rate were
derived from published surveys of such data by Korpacz & Associates, Real
Estate Research Corporation and Cushman & Wakefield. The real estate value
derived under the income approach was reduced by deferred maintenance estimates
and by closing costs estimated at 2.5% and further reduced by any mark-to-
market adjustment associated with the debt encumbering each property based upon
a 7.5% per annum interest rate. Where debt was prepayable without penalty, no
mark-to-market adjustment was made. Where debt was subject to a yield
maintenance prepayment penalty, (1) the present value of the obligations under
the mortgage through the remaining term was compared to (2) the present value
of

                                       84
<PAGE>

such obligations and any non-yield maintenance prepayment penalty at the
earliest possible prepayment date after the yield maintenance prepayment
penalty expired. The lower of the two calculations described in clauses (1) and
(2) in the preceding sentence were compared to the mortgage debt outstanding.
Where the present value of the remaining obligations exceeded the mortgage
balance, a mark-to-market adjustment for such excess was included in Stanger &
Co.'s analysis.

   The following table summarizes the range of the direct capitalization rates,
terminal capitalization rates and discount rates utilized by Stanger & Co. in
its analysis of the value of the real estate assets of each McNeil Partnership.

   Balance Sheet Review. Stanger & Co. reviewed the balance sheets of each of
the McNeil Partnerships for the years ended December 31, 1997 and 1998 and for
the three months ended March 31, 1999. Stanger & Co. identified capitalized
costs, deferred gains and other liabilities, which would not result in an asset
to be sold or liability to be assumed, and excluded such items, as appropriate,
from the analysis. Stanger & Co. also reviewed each mortgage payable by the
McNeil Partnerships and estimated liability of each mortgage payable based upon
(1) principal outstanding, (2) monthly payments, (3) interest rate, (4)
maturity date, (5) prepayment terms and (6) estimated mark-to-market adjustment
using a 7.5% per annum interest rate.

   Partnership agreement review. Stanger & Co. reviewed the limited partnership
agreement of each of the McNeil Partnerships, including the provisions relating
to the fee structure, allocation of income and term of the McNeil Partnership.

   Bid solicitation review. Stanger & Co. next reviewed the bid solicitation
process, including reviewing the offering materials and the bids received by
PaineWebber in care of McNeil Partners and the status of negotiations. Stanger
& Co. noted that PaineWebber identified eighteen potential purchasers and
provided the confidential offering memorandum describing the McNeil portfolio
to thirteen potential purchasers. See "--Background of the transaction--
Background of the auction process--Solicitation of initial bids." Ten of the

                                       85
<PAGE>

thirteen prospective purchasers submitted bids to PaineWebber. Stanger & Co.
concluded that the bid solicitation process was reasonable.

   Management company review. Stanger & Co. next determined the value of the
management assets and other assets of McREMI based on a management company
review. Stanger & Co. interviewed McNeil management personnel regarding the
history of McREMI and future business prospects and business plan and
interviewed certain accounting, financial reporting, property management,
property acquisitions and other personnel regarding existing resources and the
ability to manage existing assets and the ability to manage a larger asset
base. Stanger & Co. reviewed fee agreements associated with property
management, asset management, partnership management, asset disposition and
expense reimbursements. Stanger & Co. reviewed operating expenses and expense
estimates and prepared estimates of multi-year cash flow and reviewed cash flow
multiples for comparable management companies.

   Stanger & Co. prepared a five-year discounted cash flow analysis by
projecting cash flow from continued management of the properties for five years
and a residual value at the end of the fifth year based upon a range of cash
flow multiples of 4 to 6. The cash flow for the five-year period and the
residual value at the end of the fifth year were discounted to present value at
discount rates ranging from 12.5% to 20%, resulting in a value range of
approximately $35 million to $38 million. Stanger & Co. also reviewed eleven
comparable management company transactions with a cash flow multiple range of
5.4 to 11.4, with an average of 7.8. The midpoint of the multiple range used by
Stanger & Co. in its analysis represents a 36% discount to the average among
the comparable transactions. As a result of the management company review,
Stanger & Co. estimated the value of the business of McREMI at $35,000,000. See
"Value of Management Assets" in Table 2.

  Stanger & Co. observations regarding aggregate consideration

   Stanger & Co. noted that its estimate of the aggregate value of the real
estate assets of the McNeil Partnerships and the McREMI business was
$636,479,000 (see "Total Asset Value" and "Value of Management Assets" in Table
2), as follows:

<TABLE>

       Total real estate and property management assets............ $636,479,000
</TABLE>

   Stanger & Co. noted that the $636,479,000 total value of the assets being
acquired was less than the aggregate consideration of $644,439,803, thus
indicating an acquisition premium for the McNeil portfolio. Taking into account
Stanger & Co.'s estimate of the total fees payable to PaineWebber, the premium
totaled $4,290,803.

       Premium for the McNeil portfolio........................ $   4,290,803
</TABLE>

   Stanger & Co. concluded that because the amount of the adjusted
consideration, taking into account Stanger & Co.'s estimate of the fees payable
to PaineWebber, exceeded the total value of the assets being acquired by
WXI/McN Realty, the aggregate consideration was fair, from a financial point of
view, to the holders of each class of limited partner units in each of the
McNeil Partnerships.

  Stanger & Co. allocation analysis

   Pursuant to the terms of the Master Agreement, the parties agreed that
Stanger & Co. would allocate the aggregate consideration among (1) the general
partner interests in each of the McNeil Partnerships, (2) each

                                       86
<PAGE>

class of limited partner units in each of the McNeil Partnerships and (3) the
management assets and other assets of McREMI. The allocations and the
methodology of the allocations are described in more detail in "--Opinions and
Reports of financial advisors--Stanger & Co. allocation analysis" and the
dollar values of the individual allocations are set forth in Table 2. The
Master Agreement provides that the allocations of the aggregate consideration
by Stanger & Co. are binding on Sellers and on WXI/McN Realty, its subsidiaries
and affiliates.

   The results of the Stanger & Co. allocation analysis are discussed in more
detail below and are set forth in Table 2 immediately following that
discussion.

   The aggregate consideration in the transaction, including all outstanding
mortgage debt of the McNeil Partnerships, is $644,439,803. The aggregate
consideration was first allocated by Stanger & Co. between:

     (1) the management assets of McREMI, on the one hand (see "Partial
  McREMI Allocated Value" in Table 2); and

     (2) the McNeil Partnerships as a group, on the other hand (see "Total
  Allocated Partnership Value" in Table 2).

   This allocation was based on a ratio, the numerator of which is the sum of
the total real estate values for all of the McNeil Partnerships and the
denominator of which is the sum of the total real estate values for all of the
McNeil Partnerships and the value of the management assets of McREMI. An
aggregate of $35,236,000 has been allocated by Stanger & Co. to the management
assets of McREMI. An aggregate of $605,534,000 has been allocated by Stanger &
Co. to the McNeil Partnerships as a group. See "Total Asset Value" in Table 2.

   The $605,534,000 allocated to the McNeil Partnerships as a group was then
further allocated among each of the individual McNeil Partnerships. See
"Allocated Partnership Value" in Table 2. This allocation was based on the
percentages agreed to between Stanger & Co., in consultation with Eastdil
Realty Company, and WXI/McN Realty and set forth in the Master Agreement. See
"Partnership Percentage" in Table 2. These percentages were based on the
relative real estate values of each McNeil Partnership relative to the sum of
the real estate values for all of the McNeil Partnerships, including
adjustments with respect to specific properties to take into account the June
1, 1999 aggregate purchase price reduction of $1.65 million for additional
environmental issues that Whitehall's environmental consultant identified at
those properties at that time and for the scheduled expiration of a ground
lease at one of the properties. See "--Background of the transaction--
Background of the auction process--Negotiations of definitive transaction
documents with Whitehall."

   The amount of the aggregate consideration allocated to each individual
McNeil Partnership was further allocated, after subtracting the outstanding
principal balance, determined as of      , 1999, of all outstanding mortgage
debt of that McNeil Partnership, between:

     (1) the general partner interests taken as a whole in that McNeil
  Partnership and the other assets of McREMI related to that McNeil
  Partnership (see "MPLP Allocation Amount" in Table 2), net of any deficit
  restoration obligation, as estimated by Arthur Andersen LLP, of the general
  partner of that McNeil Partnership; and

     (2) each class of limited partner units in each McNeil Partnership,
  taken as a whole (see "LP Allocation Amount" in Table 2).

   Arthur Andersen LLP's estimates were based, in part, on limited historical
tax records prepared by other accounting firms. Sufficient records did not
exist such that Arthur Andersen LLP could test the accuracy of prior
accountants' work. Further, these estimates were based on the McNeil
Partnerships' projections of 1999 operating results through March 31, 1999 and
on hypothetical asset sale/partnership liquidation information provided by
Stanger & Co. Arthur Andersen LLP has not audited or opined on the projected
results of operations or financial information relating to such hypothetical
sales/liquidations.


                                       87
<PAGE>

   The aggregate consideration allocated to each McNeil Partnership was
allocated between classes of limited partner units based upon the provisions of
the limited partnership agreement relating to a liquidation and termination of
the McNeil Partnership. The aggregate consideration allocated to a class of
limited partners was then allocated among the limited partner units in that
class by dividing the aggregate consideration allocated to that class by the
number of outstanding limited partner units in that class. See "Per Unit Merger
Consideration" in Table 2.

   The amount of the aggregate consideration allocated in paragraph (1) above
with respect to each McNeil Partnership includes (a) an amount representing the
general partner's proportionate interest in the profits and losses of that
McNeil Partnership, based on the general partner's capital contribution, and an
amount representing the rights and other assets of that McNeil Partnership
which are being contributed to WXI/McN Realty and its subsidiaries (see "GP
Allocation Amount" in Table 2) and (b) an amount equal to the aggregate
consideration allocated by Stanger & Co. to the other assets of McREMI related
to that McNeil Partnership (see "Second McREMI Allocated Value" in Table 2). Of
the $    allocated to the general partner interests in all of the McNeil
Partnerships, $    represents the general partners' proportionate interests of
the profits and losses of the McNeil Partnerships, based on the general
partners' capital contributions, and $    represents the rights and other
assets corresponding to the McNeil Partnerships which are being contributed to
WXI/McN Realty and its subsidiaries. An aggregate of $    has been allocated to
the other assets of McREMI related to all of the McNeil Partnerships. The
aggregate consideration allocated by Stanger & Co. to all of the assets of
McREMI being acquired by WXI/McN Realty and its subsidiaries, assuming all
McNeil Partnerships participate in the transaction, is equal to the sum of the
"Partial McREMI Allocated Value" in Table 2 and the total of the amounts set
forth under "Second McREMI Allocated Value." Assuming all of the McNeil
Partnerships participate in the transaction, the "Total McREMI Allocated Value"
is equal to $    .

 (1) The numbers set forth in this Table 2 have been estimated based on the
     financial statements of the McNeil Partnerships as of March 31, 1999.
     Actual amounts, including the estimate allocable to McNeil Partners, will
     vary with the performance of the McNeil Partnership and McNeil Partners
     through the closing date. The numbers set forth in this Table 2 (other
     than the "Partnership Percentage" which are set forth in the Master
     Agreement) will be recalculated as of the date of the second Stanger &
     Co. opinion, based on the most recent financial statements and the actual
     amounts will be derived from such recalculated numbers.
 (2) As determined by Stanger & Co.
 (3) For each McNeil Partnership, this column equals (1) the "Total Asset
     Value" for that McNeil Partnership divided by (2) $636,479, which is the
     sum of the "Total Asset Values" for all McNeil Partnerships and the
     "Value of Management Assets".
 (4) As set forth in the Master Agreement.
 (5) For each McNeil Partnership, the "Allocated Partnership Value" equals the
     product of (1) $605,534, which represents the total amount allocated to
     the McNeil Partnerships, and (2) the "Partnership Percentage" for that
     McNeil Partnership.
 (6) Represents outstanding principal as of March 31, 1999.
 (7) For each McNeil Partnership, the "Net Allocated Partnership Value" equals
     (1) the "Allocated Partnership Value" less (2) the "Principal Amount of
     Mortgage Debt."
 (8) For each McNeil Partnership, the "MPLP Allocation Amount" equals the sum
     of the "GP Allocation Amount" and the "Second McREMI Allocated Value."
     The "MPLP Allocation Amount" includes all amounts payable to the McNeil
     Affiliates as reflected on the balance sheet as of March 31, 1999, less
     the deficit restoration obligation, if any, of the general partner, as
     estimated by Arthur Andersen LLP based upon a hypothetical sale of
     properties and liquidation of the McNeil Partnership at March 31, 1999.
     Arthur Andersen LLP's estimates were based, in part, on limited
     historical tax records prepared by other accounting firms. Sufficient
     records did not exist such that Arthur Andersen LLP could test the
     accuracy of prior accountants' work. Further, these estimates were based
     on the McNeil Partnerships' projections of 1999 operating results through
     March 31, 1999 and on hypothetical asset sale/partnership liquidation
     information provided by Stanger & Co. Arthur Andersen LLP has not audited
     or opined on the projected results of operations or financial information
     relating to such hypothetical sales/liquidations.
 (9) For each McNeil Partnership, the "GP Allocation Amount" is the amount of
     the aggregate consideration allocated by Stanger & Co. to the general
     partner interests taken as a whole in that McNeil Partnership.
(10) For each McNeil Partnership, the "Second McREMI Allocated Value" is the
     amount of the aggregate consideration allocated by Stanger & Co. to the
     other assets of McREMI related to that McNeil Partnership.
(11) For each class of limited partner units in each McNeil Partnership, the
     "LP Allocation Amount" is the amount of the aggregate consideration
     allocated by Stanger & Co. to that class of limited partner units taken
     as a whole.
(12) The "Partial McREMI Allocated Value" equals the aggregate consideration
     allocated by Stanger & Co. to the management assets of McREMI. The
     "Partial McREMI Allocated Value" equals the product of (1) the aggregate
     consideration of approximately $3,670 and (2) 5.50%, which is for McREMI
     the "Relative Percentage Based on Total Asset Value."

  The Master Agreement provides that the "Total McREMI Allocated Value" will be
  reduced by the product of the "Partial McREMI Allocated Value" and the
  "Partnership Percentage" for each McNeil Partnership that does not
  participate in the transaction.
(13) Aggregate consideration taking into account Stanger & Co.'s estimate of
     fees payable to PaineWebber of approximately $3,670.
(14) Sum of "LP Allocation Amounts" for the Affiliated McNeil Partnerships.
(15) The "Total McREMI Allocated Value" equals the aggregate consideration
     allocated by Stanger & Co. to all of the assets of McREMI being
     contributed by McNeil Partners to WXI/McN Realty and its subsidiaries.
     The "Total McREMI Allocated Value" equals the sum of (1) the "Partial
     McREMI Allocated Value" (see note (12) above) and (2) the sum of the
     "Second McREMI Allocated Values".
  The Master Agreement provides that the "Total McREMI Allocated Value" will be
  reduced by the sum of the following:

(a) the "Second McREMI Allocated Value" for each McNeil Partnership that does
    not participate in the transaction, and
(b) the product of the "Partial McREMI Allocated Value" and the "Partnership
    Percentage" for each McNeil Partnership that does not participate in the
    transaction.
(16) As of March 31, 1999.
(17) For each class of limited partner units in a McNeil Partnership, the "Per
     Unit Merger Consideration" equals (1) the "LP Allocation Amount" for that
     class divided by (2) the "Units Outstanding" for that class.
(18) Estimated based upon, among other things, the balance sheet of each
     McNeil Partnership as of March 31, 1999, adjusted for intangible assets,
     non-cash liabilities and amounts payable to the McNeil Affiliates as
     reflected on the balance sheet, and calculated in accordance with the
     Master Agreement. Actual amounts, including the estimate allocable to the
     McNeil Affiliates, will vary with the performance of the McNeil
     Partnership and McNeil Partners through the closing date.
(19) Represents transaction costs as estimated by McNeil Partners. Assumes
     estimated transaction costs of $695 are paid by McREMI, based on total
     estimated transaction costs of $10,154.
(20) Estimated based upon, among other things, the balance sheet of each
     McNeil Partnership as of March 31, 1999, adjusted for intangible assets,
     non-cash liabilities, transaction expenses and amounts payable to the
     McNeil Affiliates as reflected on the balance sheet. The "Estimated Total
     Net Working Capital Balance" will be re-estimated as of the date of the
     second Stanger & Co. opinion based upon a modified net working capital
     balance of the McNeil Partnership calculated in accordance with the
     Master Agreement and will be adjusted at closing to reflect the then
     modified net working capital balance of the McNeil Partnership.
(21) For each class of limited partner units in a McNeil Partnership, the
     "Estimated Per Unit Special Distribution" equals (1) the portion of the
     "Estimated Total Net Working Capital Balance" which each limited partner
     unit of that class is entitled to receive based on the provisions in that
     McNeil Partnership's limited partnership agreement governing
     distributions of surplus cash, except that the general partners of that
     McNeil Partnership will not receive any part of the special distribution.
(22) For each class of limited partner units in a McNeil Partnership, the
     "Total Per Unit Estimate" equals the sum of (1) the "Per Unit Merger
     Consideration" for that class and (2) the "Estimated Per Unit Special
     Distribution" for that class. However, if the modified net working
     capital balance for a McNeil Partnership determined as of the closing
     date of the transaction in accordance with the Master Agreement is a
     negative number, the "LP Allocation Amount" for each class of limited
     partner units in that McNeil Partnership will be reduced by the portion
     of the negative modified net working capital balance which that class is
     entitled to receive based on the provisions in that McNeil Partnership's
     limited partnership agreement governing distributions of surplus cash. As
     a result, the aggregate amount to be received per limited partner unit of
     that class will be reduced by the per unit amount of the negative
     modified net working capital balance allocable to that class based on the
     provisions in that McNeil Partnership's limited partnership agreement
     governing distributions of surplus cash, except that the general partners
     of that McNeil Partnership will not receive any part of the special
     distribution.

  Eastdil Realty Company opinions

   On May 7, 1999, the McNeil Partnerships, on behalf of the special committee,
engaged Eastdil Realty Company as its financial advisor. Eastdil Realty
Company, founded in 1967, is a private real estate investment banking firm that
specializes in the structuring and placement of debt and equity capital for
institutional grade real estate assets. Headquartered in New York City, Eastdil

billion, including transactions involving 61 million square feet of office
properties, 18.5 million square feet of retail properties, 17,000 apartment
units and 11,700 hotel rooms.

  First Eastdil Realty Company opinion

   At the June 24, 1999 meeting of the special committee, Eastdil Realty
Company delivered a verbal fairness opinion, which was subsequently confirmed
in writing, to the effect that, as of the date of the opinion, and subject to
the assumptions, qualifications and limitations set forth in the opinion:

  . the Stanger & Co. allocation analysis and the opinions set forth in the
    first Stanger & Co. opinion were based upon the application of
    appropriate methodologies, and the factual bases utilized by Stanger &
    Co. in the application of these methodologies have a reasonable basis;

  . the conclusions reached in the Stanger & Co. allocation analysis and the
    first Stanger & Co. opinion have a reasonable basis;

  . the special committee is entitled to rely upon those conclusions; and

  . each of the following five matters described below which were set forth
    in the first Stanger & Co. opinion is fair from a financial point of view
    to the holders of each class of limited partner units in each of the
    McNeil Partnerships:

    -- the aggregate consideration in the transaction;

    -- the allocation of the aggregate consideration between the management
       assets of McREMI, on the one hand, and the McNeil Partnerships as a
       group, on the other hand;

    -- the aggregate consideration allocated to each individual McNeil
       Partnership;

    -- the methodology of allocation of the aggregate consideration
       allocated to each individual McNeil Partnership, less the principal
       amount of all outstanding mortgage debt of that McNeil

                                       92
<PAGE>

       Partnership, among the general partner interests in that McNeil
       Partnership, the other assets of McREMI related to that McNeil
       Partnership and each class of limited partner units in that McNeil
       Partnership; and

    -- the estimated amount of the positive net working capital balance
       estimated to be distributed per limited partner unit in each McNeil
       Partnership and the amount of the aggregate consideration allocated
       to each limited partner unit in each McNeil Partnership, determined
       as of March 31, 1999, based upon the balance sheet of each McNeil
       Partnership as of March 31, 1999, adjusted for transaction expenses
       and the allocation of transaction expenses, as estimated by the
       McNeil General Partners.

   The written fairness opinion delivered by Eastdil Realty Company to the
special committee on June 24, 1999 is referred to in this Proxy Statement as
the "first Eastdil Realty Company opinion." In making the determinations
described in "--Recommendations of the special committee and the McNeil
Investors board of directors; fairness of the transaction--Recommendations of
the special committee," the special committee relied on, among other things,
the first Stanger & Co. opinion and the first Eastdil Realty Company opinion.

   The full text of the first Eastdil Realty Company opinion, which sets forth
the assumptions made, matters considered and qualifications and limitations on
the review undertaken by Eastdil Realty Company, is incorporated in this Proxy
Statement by reference. The first Eastdil Realty Company opinion is attached
as Appendix D-1 to this Proxy Statement. The limited partners of the
Partnership are urged to read carefully the first Eastdil Realty Company
opinion in its entirety.

  Second Eastdil Realty Company opinion

   On      , 1999, Eastdil Realty Company delivered a second written opinion
to the special committee. In this second opinion, Eastdil Realty Company
rendered additional opinions as to the fairness from a financial point of view
to the holders of each class of limited partner units in each McNeil
Partnership as to the additional matters set forth in the second Stanger & Co.
opinion. The second opinion delivered by Eastdil Realty Company on      , 1999
is referred to in this Proxy Statement as the "second Eastdil Realty Company
opinion." The second Eastdil Realty Company opinion is described in more
detail below.

   The full text of the second Eastdil Realty Company opinion, which sets
forth the assumptions made, matters considered and qualifications and
limitations on the review undertaken by Eastdil Realty Company, is
incorporated in this Proxy Statement by reference. The second Eastdil Realty
Company opinion is attached as Appendix D-2 to this Proxy Statement. The
limited partners of the Partnership are urged to read carefully the second
Eastdil Realty Company opinion in its entirety.

   The second Eastdil Realty Company opinion was to the effect that, as of the
date of the second Eastdil Realty Company opinion, and subject to the
assumptions, qualifications and limitations set forth in the second Eastdil
Realty Company opinion:

  . the Stanger & Co. allocation analysis and the opinions set forth in the
    second Stanger & Co. opinion were based upon the application of
    appropriate methodologies, and the factual bases utilized by Stanger &
    Co. in the application of these methodologies have a reasonable basis;

  . the conclusions reached in the Stanger & Co. allocation analysis and the
    second Stanger & Co. opinion have a reasonable basis;

  . the special committee is entitled to rely upon those conclusions; and

  . each of the following four matters described below which were set forth
    in the second Stanger & Co. opinion is fair from a financial point of
    view to the holders of each class of limited partner units in each of the
    McNeil Partnerships:

                                      93
<PAGE>

    . the aggregate consideration allocated to the general partner
      interests in each McNeil Partnership;

    . the aggregate consideration allocated to the other assets of McREMI
      related to each McNeil Partnership;

    . the aggregate consideration allocated to each class of limited
      partner units in each McNeil Partnership;

    . the estimated amount of the aggregate consideration allocated to each
      limited partner unit in each McNeil Partnership and the dollar amount
      of the positive net working capital balance estimated to be
      distributed per limited partner unit in each McNeil Partnership,
      determined as of      , 1999, based upon the balance sheet of each
      McNeil Partnership as of      , 1999, adjusted for transaction
      expenses and the allocation of transaction expenses, as estimated by
      the McNeil General Partners.

   In considering the opinions described in the second Eastdil Realty Company
opinion and in reading the discussion of the second Eastdil Realty Company
opinion set forth below, the limited partners in the Partnership should be
aware that Eastdil Realty Company:

  . reviewed the Master Agreement and the WXI/McN Realty Operating Agreement;

  . reviewed the latest draft of this Proxy Statement made available to it;

  . reviewed the summary information provided by McREMI, as property manager,
    the McNeil General Partners and the McNeil Partnerships for each of the
    properties owned by the McNeil Partnerships, including: property
    description, rentable square footage, unit mix, year built, historical
    and projected operating statements, rent rolls, tenant improvement
    allowances, expense reimbursements, tax information, capital expenditure
    estimates, deferred maintenance estimates and estimates of costs to
    remediate environmental conditions;

  . conducted limited site inspections of certain of the McNeil Partnerships'
    properties;

  . discussed with management of McREMI and Stanger & Co. the conditions in
    local rental markets and market conditions for sales and acquisitions of

    historical financial statements and budgeted and projected operations of
    the McNeil Partnerships' properties;

  . reviewed surveys of competing properties prepared by or on behalf of
    McREMI, the McNeil General Partners and the McNeil Partnerships,

    investors for properties similar to the McNeil Partnerships' properties
    during 1999;

  . reviewed the financial statements of McREMI and its affiliates for the

    1999 and the     months ended    , 1999;

  . interviewed PaineWebber regarding the bid solicitation process relating
    to the transaction;

  . discussed with Stanger & Co. the activities of Stanger & Co. since
    January 1998 with respect to the Stanger & Co. allocation analysis and
    the Stanger opinions;

                                       94

   In rendering its opinion, Eastdil Realty Company relied, without independent
verification, on the accuracy and completeness in all material respects of all
financial and other information that was furnished or otherwise communicated to
Eastdil Realty Company by McREMI, the McNeil General Partners and the McNeil
Partnerships. Eastdil Realty Company did not perform an independent appraisal
of the assets and liabilities of the McNeil Partnerships or the assets of
McREMI. Eastdil Realty Company did not conduct any engineering studies and
relied on the estimated cost to remediate environmental conditions for each
property.

   Eastdil Realty Company relied on the assurance of McREMI, the McNeil General
Partners and the McNeil Partnerships that:

  . the property budgets and discounted cash flow analyses provided to
    Eastdil Realty Company were, in the judgment of McREMI, the McNeil
    General Partners and the McNeil Partnerships, reasonably prepared on
    bases consistent with actual historical experience and reflect the best
    currently available estimates and good faith judgments;

  . any estimates of costs to remediate environmental conditions were
    adequately considered in the capital expenditure estimates provided to
    Eastdil Realty Company and that no additional environmental conditions
    are present at the properties;

  . any historical financial data, balance sheet data, transaction cost
    estimates and estimates of the deficit restoration obligation of the
    McNeil General Partners which would be due upon a liquidation were
    accurate in all material respects;

  . no material changes have occurred in the information reviewed or in the
    value of the properties or the business or other assets of McREMI between
    the date the information was provided to Eastdil Realty Company and the
    date of its opinion; and

  . McREMI, the McNeil General Partners and the McNeil Partnerships were not
    aware of any information or facts regarding the McNeil Partnerships, the
    properties, the business or other assets of McREMI or WXI/McN Realty that
    would cause the information supplied to Eastdil Realty Company to be
    incomplete or misleading in any material respect.

   Eastdil Realty Company did not determine or negotiate the amount or form of
the aggregate consideration in the transaction. Eastdil Realty Company was not
requested to, and therefore did not:

  . make any recommendation to McREMI, the McNeil General Partners or the
    limited partners of the McNeil Partnerships with respect to whether to
    approve or reject the transaction; or

  . express any opinion as to:

    -- the impact of the transaction with respect to McREMI, the McNeil
       General Partners, or the limited partners of any McNeil Partnership
       that does not participate in the transaction;

    -- the tax consequences of the transaction for McREMI, the McNeil
       General Partners or the limited partners of any McNeil Partnership;

    -- WXI/McN Realty's ability to qualify as a partnership or real estate
       investment trust, or the consequences of WXI/McN Realty's failure to
       so qualify;

    -- the potential capital structure of WXI/McN Realty or its impact on
       the financial performance of WXI/McN Realty's membership interests;

    -- WXI/McN Realty's ability to finance its obligations pursuant to the
       Master Agreement or the impact of a failure to obtain financing on
       the financial performance of WXI/McN Realty or the McNeil
       Partnerships;

    -- whether or not alternative methods of determining or allocating the
       aggregate consideration to be received by the McNeil General
       Partners, the limited partners of the McNeil Partnerships or McREMI
       would have also provided fair results or results substantially
       similar to those of the methodology used;

                                       95
<PAGE>

    -- alternatives to the transaction; or

    -- any other terms of the transaction other than the aggregate
       consideration and the allocation of the aggregate consideration.

   Furthermore, Eastdil Realty Company did not express any opinion to Robert A.
McNeil or Carole J. McNeil in their capacities as direct or indirect holders of
general partner interests or limited partner units in the McNeil Partnerships
or McNeil Partners or of capital stock in McREMI. Further, Eastdil Realty
Company did not express any opinion as to the fairness of any terms of the
transaction other than as described therein, including, without limitation:

  . the fairness of the amounts or allocations of transaction costs;

  . the prices at which the membership interests in WXI/McN Realty may trade,
    if the membership interests were traded, following the transaction; and

  . the trading value of the membership interests in WXI/McN Realty, if the
    membership interests were traded, compared with the current fair market
    value of any assets contributed to WXI/McN Realty in connection with the
    transaction if WXI/McN Realty were to be liquidated in the current real
    estate market.

   The second Eastdil Realty Company opinion did not purport to be a complete
description of the analyses performed or the matters considered in rendering
the second Eastdil Realty Company opinion. The analyses and the summary set
forth in the second Eastdil Realty Company opinion must be considered as a
whole, and selecting portions of such summary or analyses, without considering
all factors and analyses, would create an incomplete view of the processes
underlying the second Eastdil Realty Company opinion. In rendering the second
Eastdil Realty Company opinion, judgment was applied to a variety of complex
analyses and assumptions. The assumptions made and the judgments applied in
rendering the second Eastdil Realty Company opinion are not readily susceptible
to partial analysis or summary description. The fact that any specific analysis
is referred to in the second Eastdil Realty Company opinion or in this Proxy
Statement is not meant to indicate that such analysis was given greater weight
than any other analysis.

  Financial analysis of Eastdil Realty Company

   Eastdil Realty Company completed a full review of all Stanger & Co.'s files
compiled in connection with this transaction. These files contained base
information such as property inspection reports, rent and sale comparable
properties reports, market supply and demand trends, description of physical
and environmental issues (if any), appraisals (available for a limited number
of properties), offers to purchase, historic and projected revenues, operating
expenses and real estate taxes. Eastdil Realty Company did conduct limited site
inspections of certain properties to confirm or clarify base file information.
From McREMI, Eastdil Realty Company reviewed market surveys, historic and
projected income statements, property occupancy trends and other related
information to confirm and better understand Stanger & Co. file information and
conclusions. This base information was then reviewed in the context of detailed
cash flow projections prepared by Stanger & Co.

   Eastdil Realty Company then determined if the projection assumptions, such
as market rental rates, market rental rate growth, vacancy (both current and
stabilized) expense ratios, projected capital expenditures, expense growth
rates, timing for lease-up of vacant space/vacant units and capital costs
associated with leasing vacant space in the retail and office properties were
reasonable given the base file information and Eastdil Realty Company's
understanding of investor underwriting parameters in the current capital market
environment. Several minor disagreements regarding projection assumptions were
discussed and resolved with Stanger & Co.

   Eastdil Realty Company then analyzed the valuation parameters used by
Stanger & Co. Apartments and self-storage facilities were valued by both
Stanger & Co. and Eastdil Realty Company primarily based on direct
capitalization; discounted cash flow analysis was used as a secondary valuation
method. Valuations for office and retail properties by both Stanger & Co. and
Eastdil Realty Company were based on discounted cash flow analysis. For
apartment and self-storage properties, Eastdil Realty Company prepared summary
1999 net

                                       96
<PAGE>

operating income projections and applied capitalization rates based on Eastdil
Realty Company's current market experience and information contained in the
Stanger & Co. files. Nearly all of Eastdil Realty Company's capitalization rate
assumptions fell within Stanger & Co.'s range of 8.5% to 11.0% for apartments
and 9.5% to 9.75% for self storage. Some minor differences in capitalization
rate estimates were adequately addressed and resolved.

   Eastdil Realty Company reviewed Stanger & Co.'s office and retail property
cash flow valuation parameters against Eastdil Realty Company's current market
experience. Cash flow projections were reproduced with Eastdil Realty Company's
valuation parameters; these results were then compared with Stanger & Co.'s
valuation results. After reconciliation of minor discrepancies and
interpretation differences, nearly all of Eastdil Realty Company's office and
retail valuation results used valuation parameters in the range used by Stanger
& Co. For office properties, a discount rate range of 11.25% to 12.5% and a
terminal capitalization rate range of 9.5% to 11.0% was used. For retail
properties, the discount rate range is 11.5% to 13.5%, and the terminal
capitalization rate range is 10.0% to 12.0%. These valuation parameters were
used for a ten-year cash flow projection, the predominant projection period
used by investors in today's market.

   Eastdil Realty Company reviewed Stanger & Co.'s valuation for McREMI. This
review included analysis of Stanger & Co.'s six-year cash flow projection
beginning in 1999; the cash flow projection included property management fees,
asset management fees, expense reimbursements and operating expenses.
Compilation of the cash flow line items were discussed with McNeil management
and the underlying assumptions were examined by Eastdil Realty Company and
compared with historic results. No discrepancies or unreasonable assumptions
were identified. Eastdil Realty Company then reviewed Stanger & Co.'s valuation
methodology, which is a discounted cash flow analysis over a five-year holding
period; the residual calculation is a cash flow multiple applied to year six
cash flow. Eastdil Realty Company concluded that this methodology is
appropriate. Stanger & Co. utilizes a discount rate range of 12.5% to 20.0% and
a reversion multiple of 4x to 6x year six cash flow. Eastdil Realty Company
concluded that these valuation parameters are reasonable.

  Fee arrangements

   Pursuant to the terms of the engagement letter with Eastdil Realty Company,
on behalf of the special committee, the McNeil Partnerships have agreed to pay
Eastdil Realty Company a total fee equal to $500,000. The total fee is payable
as follows:

  . $100,000 had been paid prior to execution of the Master Agreement and
    prior to delivery of the first Eastdil Realty Company opinion;

  . $300,000 became payable to Eastdil Realty Company upon the delivery of
    the first Eastdil Realty Company opinion; and

  . $100,000 became payable upon the delivery of the second Eastdil Realty
    Company opinion.

   In addition, the McNeil Partnerships have agreed to reimburse Eastdil Realty
Company for all reasonable out-of-pocket expenses incurred by Eastdil Realty
Company in connection with Eastdil Realty Company's services, but not including
the fees or disbursements of Eastdil Realty Company's legal counsel, if any.
The McNeil Partnerships also have agreed to indemnify Eastdil Realty Company
against certain liabilities in connection with its engagement, including
certain liabilities under the federal securities laws. In general, each of the
McNeil Partnerships will be liable to pay its ratable share of Eastdil Realty
Company's fees and expenses based upon its "Partnership Percentage" in Table 2.
See "The Master Agreement--Fees and expenses."

Position of McNeil Partners and Robert A. McNeil regarding the transaction

   Each of McNeil Partners and Robert A. McNeil has concluded that the merger
proposal is fair to the limited partners of each of the McNeil Partnerships.
The conclusions of McNeil Partners and Robert A. McNeil were based upon the
determinations of the McNeil Investors board of directors, the determination
and

                                       97
<PAGE>

recommendation of the special committee, the factors that were considered by
the special committee and the fairness opinions delivered to the McNeil
Investors board of directors by Stanger & Co. on behalf of the McNeil
Partnerships and the opinions delivered to the special committee by Eastdil
Realty Company.

   McNeil Partners and Robert A. McNeil have each adopted the analyses of the
special committee and the McNeil Investors board of directors in support of
their conclusions. Robert A. McNeil is the Co-Chairman of the McNeil Investors
board of directors and the sole stockholder of McNeil Investors and
participated in the deliberations of the McNeil Investors board of directors.
McNeil Investors is the general partner of McNeil Partners and therefore has
the power to take action on behalf of and make decisions on behalf of McNeil
Partners. As disclosed in the section entitled "--Interests of certain persons
in matters to be acted upon; conflicts of interest," each of McNeil Partners
and Robert A. McNeil has a financial interest in the transaction and interest
in the transaction that differ from those of the Partnership's limited
partners.

Interests of certain persons in matters to be acted upon; conflicts of interest

   In considering the recommendation of the McNeil Investors board of
directors, limited partners of the McNeil Partnerships should be aware that the
McNeil Affiliates have interests in the transaction or relationships, including
those referred to below, that may present actual or potential conflicts of
interest in connection with the transaction. The special committee and the
McNeil Investors board of directors were aware of these actual or potential
conflicts of interest and considered them (as described in "--Recommendations
of the special committee and the McNeil Investors board of directors; fairness
of the transaction") along with other matters described in "--Recommendations
of the special committee and the McNeil Investors board of directors; fairness
of the transaction" and "--Effects of the transaction--Benefits and detriments
to the McNeil Affiliates." The special committee considered the conflicts of
interest of the McNeil Affiliates to be a negative factor in its determination
that the merger proposal is fair to, and in the best interests of, the limited
partners of each of the McNeil Partnerships and its determination to recommend
to the McNeil Investors board of directors the approval of the merger proposal.
See "--Recommendations of the special committee and the McNeil Investors board
of directors; fairness of the transaction--Recommendations of the special
committee."

   Regardless of the actual or potential conflicts of interest of the McNeil
Affiliates, each McNeil General Partner is accountable to each of the McNeil
Partnerships of which it is a general partner, whether directly or indirectly,
and has fiduciary duties and is obligated to exercise good faith and fair
dealing toward the limited partners of each of the McNeil Partnerships of which
it is a general partner. In addition, the McNeil Investors board of directors
has fiduciary duties and is obligated to exercise good faith and fair dealing
toward the limited partners of the McNeil Partnerships of which McNeil Partners
is the general partner. The McNeil Affiliates also believe that the factors
enumerated in "--Recommendations of the special committee and the McNeil
Investors board of directors; fairness of the transaction--Recommendations of
the special committee" and "--Opinions and reports of financial advisors,"
including the fact that the transaction requires the approval of the limited
partners of each of the McNeil Partnerships, provide sufficient procedural
safeguards to minimize the effects of any actual or potential conflicts of
interest of the McNeil Affiliates in the transaction.

 Relationships among the McNeil Affiliates and the McNeil Partnerships

   The relationships among the McNeil Affiliates and the McNeil Partnerships
may create significant conflicts of interest in connection with the
transaction. See "Summary--Structure of the transaction--Ownership of the
McNeil Partnerships immediately prior to the transaction." McNeil Investors is
the general partner of McNeil Partners. McNeil Investors is wholly owned by
Robert A. McNeil. The sole limited partner of McNeil Partners is Robert A.
McNeil. Robert A. McNeil and Carole J. McNeil also hold two of the four seats
on the McNeil Investors board of directors and each serves as a Co-Chairman of
the McNeil Investors board of directors. The third board seat is held by Ron K.
Taylor, the President of McNeil Investors and McREMI. The fourth board seat is
held by Paul B. Fay, Jr., an independent director. Mr. Fay is also the sole
member of the special committee. See "Controlling Persons, Directors and
Executive Officers of McNeil Partners, McNeil Investors, WXI/MNL Real Estate,
L.L.C., WH Advisors, L.L.C. XI and The Goldman Sachs Group, Inc.--Background of
named persons--McNeil Partners and McNeil Investors."

 Ownership of limited partner units in the McNeil Partnerships by the McNeil
 Affiliates
   In addition to owning limited partner units in the Affiliated McNeil
Partnerships, McNeil Partners and some of its affiliates beneficially own
limited partner units in some of the other McNeil Partnerships. McNeil Partners
and these affiliates intend to vote all of the limited partner units
beneficially owned by them in each of the McNeil Partnerships for the merger
proposal with respect to that McNeil Partnership. See "Related Security Holder
Matters--Principal holders of limited partner units."

   McNeil Partners and its affiliates are entitled to receive the same
estimated per unit aggregate amount for each of the limited partner units owned
by them in a participating McNeil Partnership, other than an Affiliated McNeil
Partnership, as all of the other limited partners in that McNeil Partnership
are entitled to receive. If all of the McNeil Partnerships in which McNeil

Partnerships, McNeil Partners and these affiliates will have the right to
receive an aggregate amount of approximately $           in cash. This amount
consists of both the merger consideration and the estimated special
distribution to be received for those limited partner units.

 Structuring of the transaction by the McNeil General Partners

   The transaction has been initiated and structured by the McNeil General
Partners and individuals who are executive officers of McNeil Investors and
McREMI. See "--Purposes and reasons for the transaction" and

                                      100
<PAGE>

"--Background of the transaction--Background of the auction process--
Structuring of the transaction." The transaction provides some benefits to the
McNeil Affiliates that may be in conflict with the benefits provided to the
limited partners of the McNeil Partnerships. See "--Effects of the
transaction--Benefits and detriments to the McNeil Affiliates."

   In recognition of the actual or potential conflicts of interest of the
McNeil General Partners and some members of the McNeil Investors board of
directors in negotiating the terms of the transaction and in evaluating the
transaction on behalf of the limited partners of the McNeil Partnerships,
following preliminary discussions with Whitehall, the McNeil Investors board of
directors constituted the special committee. See
"--Background of the transaction--Background of the auction process--
Appointment of the special committee." The special committee participated,
through its legal counsel and financial advisor, in negotiating the forms,
terms and conditions of the definitive agreements in respect of the
transaction. The special committee, with the assistance of its legal counsel
and financial advisor, also reviewed and passed upon the terms of the
transaction on behalf of the limited partners of the McNeil Partnerships and
independently recommended to the McNeil Investors board of directors that the
transaction be approved. In addition, each of the McNeil Partnerships retained
Stanger & Co. as its independent advisor. Stanger & Co. has performed the
Stanger & Co. allocation analysis and rendered the Stanger & Co. opinions. The
aggregate consideration in the transaction has been allocated by Stanger & Co.
as described in the Stanger & Co. allocation analysis and as set forth in Table
2. See "--Opinions and reports of financial advisors--Allocation analysis and
opinions of Stanger & Co." In addition, Eastdil Realty Company, the financial
advisor to the special committee, has rendered the Eastdil Realty Company
opinions. See "--Opinions and reports of financial advisors--Eastdil Realty
Company opinions."

   The McNeil Investors board of directors has unanimously determined that the
merger proposal is fair to and in the best interests of the Partnership and its
limited partners. In making its determination, the McNeil Investors board of
directors relied on the recommendation of a special committee of the McNeil
Investors board of directors and on the Stanger & Co. opinions to the effect
that each of the aggregate consideration, the allocations of the aggregate
consideration and the estimated aggregate amount to be received per limited
partner unit in the Partnership is fair from a financial point of view to the
holders of [each class of] [the] limited partner units in the Partnership. See
"--Recommendations of the special committee and the McNeil Investors board of
directors; fairness of the transaction--Recommendations of the McNeil Investors
board of directors." The special committee relied, among other things, upon the
Stanger & Co. opinions and the Eastdil Realty Company opinions in determining
that the merger proposal is fair to, and in the best interests of, the holders
of limited partner units in the McNeil Partnerships and in determining to
recommend to the McNeil Investors board of directors the approval of the merger
proposal. See "--Recommendations of the special committee and the McNeil
Investors board of directors; fairness of the transaction--Recommendations of
the special committee."

   In addition, the terms of the transaction have been reviewed and approved by
counsel to the plaintiffs in the Schofield litigation. See "--Background of the
transaction--Background of the Schofield litigation."

 Receipt of aggregate consideration by the McNeil Affiliates

   The aggregate consideration in the transaction has been allocated by Stanger
& Co. as described in the Stanger & Co. allocation analysis and as set forth in
Table 2. See "--Opinions and reports of financial advisors--Allocation analysis
and opinions of Stanger & Co.--Stanger & Co. allocation analysis." Based upon
the Stanger & Co. allocation analysis and the Stanger & Co. opinions, the
McNeil Investors board of directors and the special committee have unanimously
approved the allocations of the aggregate consideration. The special committee
also relied on the Eastdil Realty Company opinions in approving the allocations
of the aggregate consideration.

   McNeil Partners will receive an aggregate of $   , if all of the McNeil
Partnerships participate in the transaction, in consideration for its
contributions to WXI/McN Realty and its subsidiaries of the interests, rights

                                      101
<PAGE>

and assets related to the participating McNeil Partnerships. See "Total
Allocated McNeil Value" in Table 2. The "Total Allocated McNeil Value" is equal
to the aggregate consideration allocated by Stanger & Co. to the general
partner interests in the McNeil Partnerships, the limited partner interests in
the Affiliated McNeil Partnerships and the assets of McREMI being contributed
to WXI/McN Realty and its subsidiaries. See "--Opinions and reports of
financial advisors--Allocation analysis and opinions of Stanger & Co.--Stanger
& Co. allocation analysis." If not all the McNeil Partnerships participate in
the transaction, the Total Allocated McNeil Value will be equal to the sum of
the following: (1) for each participating McNeil Partnership, the sum of the
amounts set forth in the column entitled "GP Allocation Amount;" (2) for
Fairfax, if it is a participating McNeil Partnership, the amount set forth in
the column entitled "LP Allocation Amount;" (3) for McNeil Summerhill I, L.P.,
if it is a participating McNeil Partnership, the amount set forth in the column
entitled "LP Allocation Amount;" and (4) the "Total McREMI Allocated Value,"
adjusted for non-participating McNeil Partnerships as described in Table 2. The
portion of the aggregate consideration to be received by McNeil Partners in
consideration of these contributions will be paid in membership interests in
WXI/McN Realty. See "--Interests of certain persons in matters to be acted
upon; conflicts of interest--Equity ownership of McNeil Partners in WXI/McN
Realty" and "WXI/McN Realty Operating Agreement." The other McNeil Affiliates
will own partnership interests in McNeil Partners following the effective time
of the mergers. See "The Master Agreement--The contributions--Contributions to
McNeil Partners by the other McNeil Affiliates."

   McNeil Partners and its affiliates also will receive cash consideration for
the limited partner units that they own in the McNeil Partnerships. See "--
Interests of certain persons in matters to be acted upon; conflicts of
interest--Ownership of limited partner units in the McNeil Partnerships by the
McNeil Affiliates."

 Equity interest of McNeil Partners in WXI/McN Realty

   Following the effective time of the merger, McNeil Partners and WXI/McN
Realty's managing member will be the sole members of WXI/McN Realty. See
"WXI/McN Realty Operating Agreement." It is anticipated that immediately
following the effective time of the merger, McNeil Partners will own in the
aggregate between approximately  % and  % of the then outstanding membership
interests of WXI/McN Realty, depending on the amount of financing obtained by
WXI/McN Realty as of the closing and the amount of the capital contributions of
McNeil Partners. The other McNeil Affiliates will indirectly beneficially own
an equity interest in WXI/McN Realty as a result of their ownership of
partnership interests in McNeil Partners. See "The Master Agreement--The
contributions--Contributions to McNeil Partners by the other McNeil
Affiliates." Because the limited partners of the McNeil Partnerships will
receive cash in exchange for their limited partner units in the participating
McNeil Partnerships, other than the Affiliated McNeil Partnerships, the McNeil
Affiliates, as a result of their right to receive membership interests in
WXI/McN Realty, may have an economic interest in the transaction that is in
conflict with the economic interest of the other limited partners of the McNeil
Partnerships.

   McNeil Partners will receive an equity interest in and credit for a capital
contribution to WXI/McN Realty in exchange for the following:

  (1)  the contributions of interests, rights, and assets to WXI/McN Realty
       and its subsidiaries described above in "--Interests of certain
       persons in matters to be acted upon; conflicts of interest--Receipt of
       aggregate consideration by the McNeil Affiliates;"

  (2)  cash contributions to WXI/McN Realty under the circumstances described
       below; and

  (3)  the treatment as a contribution-in-kind to WXI/McN Realty of certain
       fees, expenses and disbursements incurred by the McNeil Affiliates in
       connection with the transaction, as further described below.

   The amount of the cash contribution of McNeil Partners described in
paragraph (2) above may range from zero to a maximum amount equal to the
difference determined by subtracting the Total Allocated McNeil Value from $100
million. Notwithstanding the foregoing, if the Total Allocated McNeil Value is
less than the

                                      102
<PAGE>

Minimum Investment (as defined below), McNeil Partners is required by the
Master Agreement to make a cash contribution to WXI/McN Realty in an amount
equal to the difference determined by subtracting the Total Allocated McNeil
Value from the Minimum Investment. "Minimum Investment" means the product
determined by multiplying $60 million by the sum of the percentages set forth
in the column "Partnership Percentage" in Table 2 opposite the name of each
participating McNeil Partnership.

   The Master Agreement also provides that any fees, expenses and
disbursements, including assumption fees, prepayment fees and other transaction
expenses, incurred and paid by the McNeil Affiliates in connection with the
transaction, subject to the limitations set forth in the following two
sentences, will be treated as a contribution-in-kind to WXI/McN Realty by
McNeil Partners in exchange for membership interests in WXI/McN Realty. These
fees, expenses and disbursements are subject to documentation and approval by
the WXI/McN Realty board of managers, which approval shall not be unreasonably
withheld or delayed. In addition, the amount of the fees, expenses and
disbursements that are treated as a contribution-in-kind to WXI/McN Realty by
McNeil Partners may not exceed one-half of the aggregate amount of fees,
expenses and disbursements charged to WXI/McN Realty, its subsidiaries and
affiliates by Sullivan & Cromwell with respect to negotiating and documenting
the transaction.

 Retention and employment agreements

   After the auction process began in late 1997, McNeil management became
concerned that some officers and key employees would leave McREMI during the
sale process. To encourage these officers to remain employed with McREMI until
the completion of a sale transaction, in March 1998, McREMI entered into
retention agreements with these officers and employees. These agreements, as
amended, provide that upon the closing of the transaction, McREMI will be
obligated to pay those officers and employees that remain employed by McREMI on
the closing date an aggregate of $      , of which $    will be paid by McREMI
and $    will be paid by the McNeil Partnerships regardless of whether any
particular McNeil Partnership participates in the transaction. The amounts
payable under the retention agreements will be paid in lieu of other amounts
that would have been payable in connection with the transaction under the
employment agreements that some of these individuals had entered into in their
capacities as officers of McREMI and McNeil Investors.

   One of the officers and key employees with whom McREMI entered into a
retention agreement is Ron K. Taylor. Mr. Taylor is a director and President of
McNeil Investors and McREMI, and in these capacities he participated in the
negotiation of the Master Agreement. Pursuant to his retention agreement, upon
the closing of the transaction, Mr. Taylor will be paid $       , of which
$     will be paid by McREMI and $    will be paid by the McNeil Partnerships
regardless of whether any particular McNeil Partnership participates.

 Special committee

   The special committee met   times from the time of its formation in May 1999
through the date of this Proxy Statement. The special committee member is
entitled to receive from McNeil Investors a fee in the amount of $25,000 for
each meeting of the McNeil Investors board of directors at which he is present
and for each meeting of the special committee, up to a maximum fee of $125,000.
In addition, the special committee member will be reimbursed by McNeil
Investors for his out-of-pocket travel and other reasonable expenses, including
reasonable attorneys' fees and expenses, incurred in connection with his
service as an independent director of McNeil Investors and as a member of the
special committee, in a manner consistent with McNeil Investors's policies and
procedures pertaining to the reimbursement of the expenses incurred by members
of its board of directors. The special committee member also is entitled to
certain indemnification rights from McNeil Investors, Robert A. McNeil and
Carole J. McNeil and to directors' and officers' liability insurance which will
be continued by McNeil Investors following the closing of the transaction.

                                      103

Financing; sources of funds

   The total amount of funds required by WXI/McN Realty in connection with the
consummation of the transaction, assuming all McNeil Partnerships participate
in the transaction, is estimated to be approximately $      , including:

  . payment of the cash merger consideration to the limited partners of the
    McNeil Partnerships in the amount of approximately $         ;

  . repayment of mortgage debt of the McNeil Partnerships in the aggregate
    amount of approximately $     ;

  . payment of prepayment fees relating to mortgage debt of the McNeil
    Partnerships that will be repaid at closing and the payment of the
    assumption fees that WXI/McN Realty is required to pay pursuant to the
    Master Agreement in the aggregate amount of approximately $      (see
    "The Master Agreement--Aggregate consideration--Prepayment and assumption
    of mortgage debt");

  . the amount of the shortfall, if any, of the amount of cash on hand held
    by each of the participating McNeil Partnerships at the time of the
    closing from the estimated special distribution that each participating
    McNeil Partnership is expected to make (which shortfall, as of the date
    of this Proxy Statement, is estimated to be approximately $         );
    and

  . all other expenses expected to be incurred in connection with the
    transaction and other amounts that WXI/McN Realty is required to pay
    pursuant to the terms of the Master Agreement in the aggregate amount of
    approximately $              .

   The above amounts would vary in the event that one or more of the McNeil
Partnerships are not participating McNeil Partnerships or in the event that the
amount of special distributions, expenses or other amounts vary from the
estimated amounts included above.

   It is expected that the amount of funds required by WXI/McN Realty in
connection with the transaction will be obtained through a combination of
equity and debt financing. Pursuant to the terms of the WXI/McN Realty
Operating Agreement, the managing member of WXI/McN Realty, which is owned by
Whitehall and Archon, has agreed to contribute to WXI/McN Realty an amount in
cash equal to the amounts described above. Pursuant to the terms of an equity
commitment letter from Whitehall to WXI/McN Realty, Whitehall has agreed to
provide, or to cause one or more of its affiliates to provide, a cash capital
contribution to WXI/McN Realty in an amount equal to the amounts described
above. The funds to be used by Whitehall to meet its funding commitments are
expected to come from capital contributions from the partners in Whitehall. It
is also expected that WXI/McN Realty will obtain third party mortgage or other
financing that will provide a portion of the amount of required funds described
above, although WXI/McN Realty has not, as of the date of this Proxy Statement,
entered into any agreements with respect to any third party mortgage or other
financing.

Fees and expenses relating to the transaction

   Except as described in "The Master Agreement--Fees and expenses," whether or
not the transaction is consummated, all costs and expenses incurred in
connection with the Master Agreement and the other transaction documents will
be paid by the party incurring those costs and expenses.

   Without limiting the generality of the foregoing paragraph, whether or not
the transaction is consummated, McREMI has agreed that it will be liable for
the transaction expenses incurred by McREMI on behalf of itself and not on
behalf of the McNeil Partnerships or the McNeil Partnerships' subsidiaries.
Whether or not the transaction is consummated, each McNeil Partnership has
agreed that it will be liable for the amount of

                                      104
<PAGE>

transaction expenses actually incurred by it on behalf of itself and its
subsidiaries and an amount equal to that McNeil Partnership's ratable share of
transaction expenses incurred by Sellers that are not specifically identifiable
to individual McNeil Partnerships based on the relative percentage set forth in
the column "Partnership Percentage" in Table 2 opposite the name of that McNeil
Partnership.

   In addition, in some circumstances, WXI/McN Realty will receive a break-up
fee, calculated on a partnership by partnership basis, up to an aggregate
maximum of $18.0 million, if the Master Agreement is terminated. These
circumstances are described in "The Master Agreement--Fees and expenses--
Partnership break-up fees." In addition, in some circumstances if the Master
Agreement is terminated, Sellers and WXI/McN Realty may be required to
reimburse some of the other's expenses incurred in connection with the
transaction. See "The Master Agreement--Fees and expenses--Reimbursement of
expenses."

   The following are estimates of the fees and expenses which the Partnership,
the other McNeil Partnerships, the McNeil Affiliates and WXI/McN Realty expect
to incur in connection with the transaction:

Plans for the McNeil Partnerships that participate in the transaction

   As a result of the transaction, each of the participating McNeil
Partnerships will become an indirect wholly owned subsidiary of WXI/McN Realty.
WXI/McN Realty or a wholly owned subsidiary of WXI/McN Realty will become the
sole limited partner of each of the participating McNeil Partnerships, and
separate indirect wholly owned subsidiaries of WXI/McN Realty, each of which
will become the sole general partner of one or more of the participating McNeil
Partnerships, will acquire the assets of McNeil Partners related to the
participating McNeil Partnerships. A separate indirect wholly owned subsidiary
of WXI/McN Realty will own and operate the assets of McREMI contributed to
WXI/McN Realty and its subsidiaries.

   Following consummation of the transaction, WXI/McN Realty will own, directly
or indirectly, all of the participating McNeil Partnerships and their
respective properties. It is expected that WXI/McN Realty will own, directly or
indirectly, and operate the participating McNeil Partnerships and their
properties after consummation of the transaction in a manner that is, except as
otherwise described below, generally consistent with past practice. WXI/McN
Realty may, however, increase capital expenditures made with respect to the
properties of the participating McNeil Partnerships, including with a view to
"repositioning" those properties, and make other changes as are deemed
appropriate by WXI/McN Realty.

   It is expected that WXI/McN Realty will, contemporaneous with the closing of
the transaction, cause some of the participating McNeil Partnerships or their
subsidiaries to incur mortgage and other financing and that the proceeds of
that financing will, among other things, be used to repay the indebtedness that
will be repaid at the closing of the transaction. In addition, at times as
WXI/McN Realty may determine, WXI/McN Realty may cause some of the
participating McNeil Partnerships or their subsidiaries to refinance currently
existing

                                      105
<PAGE>

indebtedness that will not be repaid in connection with the closing of the
transaction. In both cases, the principal amount of that indebtedness incurred
by the participating McNeil Partnerships or their subsidiaries may be
materially greater than the principal amount of indebtedness currently owed by
the participating McNeil Partnerships or their subsidiaries. As a result, the
"leverage" of the participating McNeil Partnerships would increase.

   As described under "WXI/McN Realty Operating Agreement--Supermajority voting
rights ," the WXI/McN Realty Operating Agreement imposes some restrictions on
the ability of WXI/McN Realty to sell multifamily assets of the participating
McNeil Partnerships prior to the fifth anniversary of the closing of the
transaction. Although WXI/McN Realty has not made any definite decisions
relating to sales of assets as of the date of this Proxy Statement, WXI/McN
Realty currently plans to dispose of some of the multifamily assets of the
participating McNeil Partnerships following the fifth anniversary of the
closing date. In addition, WXI/McN Realty plans to dispose of some of the
commercial assets of the participating McNeil Partnerships over time following
the closing of the transaction.

   The subsidiary of WXI/McN Realty which will own and operate the assets of
McREMI contributed to WXI/McN Realty and its subsidiaries is referred to in
this Proxy Statement as "Management LLC." The Master Agreement provides that
for a period ending no sooner than December 31 of the calendar year following
the calendar year in which the closing occurs, WXI/McN Realty will cause
Management LLC to continue using certain of the assets of McREMI contributed in
the transaction to WXI/McN Realty and its subsidiaries, subject to certain
rights to cease using McREMI assets if WXI/McN Realty reasonably determines
that the continued use of those assets is not supported by sound business
practices and to substitute more appropriate assets if WXI/McN Realty
determines that substitution would be sound business practice. The Master
Agreement also provides that Management LLC will make offers of employment to
some employees of McREMI. See "The Master Agreement--Material covenants--
Operation of McREMI assets."

   Under the terms of the WXI/McN Realty Operating Agreement, Management LLC
will be engaged as the property manager for the multifamily properties owned by
the participating McNeil Partnerships, and Management LLC or another property
manager, such as Archon, will initially be engaged as the property manager for
the commercial properties owned by the participating McNeil Partnerships. In
addition, the WXI/McN Realty Operating Agreement provides that Archon will
initially be engaged as the portfolio manager for the properties owned by the
participating McNeil Partnerships.

   WXI/McN Realty intends to evaluate the business, assets, organizational
structure, policies, management and personnel of the participating McNeil
Partnerships over time and consider what other changes, if any, would be
desirable in the operations of the participating McNeil Partnerships and the
properties following the closing date. There is no assurance that the plans
described above will be realized or that WXI/McN Realty will not change its
current intentions in light of the circumstances existing at the time of those
evaluations.

Plans for the McNeil Partnerships that do not participate in the transaction

   If the limited partners of the Partnership do not approve the merger
proposal, the Partnership will not participate in the transaction. As a result,
the limited partners of the Partnership will continue to own limited partner
units in the Partnership and McNeil Partners will continue to serve as the
general partner of the Partnership. Because McNeil Partners is obligated under
the Partnership's limited partnership agreement to use commercially reasonable
efforts to complete the liquidation and termination of the Partnership by
December 31, 1999, if the limited partners do not approve the merger proposal,
McNeil Partners will continue to explore alternative transactions to liquidate
the Partnership. There is no assurance, however, that, if the limited partners
do not approve the merger proposal, McNeil Partners could arrange an
alternative transaction involving the Partnership or that any alternative
transaction would result in distributions to limited partners of equal or
greater value than are estimated in connection with the transaction. In the
meantime, if the limited partners do not approve the merger proposal, McREMI,
or another property manager selected by McNeil Partners, will manage the
Partnership's properties pending a liquidation.

[For Funds XX-XXVI: Dissenters' rights

   Under Article 7.6 of the California Revised Limited Partnership Act, any
limited partner of the Partnership who does not wish to accept the merger
consideration may dissent from the merger proposal and require the Partnership
to purchase for cash, at their fair market value, the limited partner units
owned by that limited partner, provided that the limited partner complies with
the provisions of Article 7.6 of the California Revised Limited Partnership
Act.

   The following discussion is not a complete statement of the law pertaining
to dissenters' rights under California law, and is qualified in its entirety by
the full text of Article 7.6, which is provided in its entirety in Appendix E
to this Proxy Statement. All references in Article 7.6 and in this summary to a
"limited partner" are to the record holder of the limited partner units in the
Partnership as to which dissenters' rights are being asserted. A person having
a beneficial interest in limited partner units held of record in the name of
another person, such as a broker or nominee, must act promptly to cause the
record holder to follow properly the steps summarized below and in timely
manner to perfect dissenters' rights.

   Any limited partner who wishes to exercise dissenters' rights or who wishes
to preserve the right to do so should review carefully the following discussion
and Appendix E. Failure to timely and properly comply with the procedures
specified in Article 7.6 will result in the loss of dissenters' rights.
Moreover, because of the complexity of the procedures for exercising
dissenters' rights, the Partnership believes that limited partners who consider
exercising their dissenters' rights should seek the advice of counsel.

 Requirements for exercise of dissenters 'rights

   Any limited partner wishing to exercise the right under Article 7.6 to
dissent from the merger proposal and demand that the Partnership purchase for
cash, at their fair market value, the limited partner units owned by that
limited partner must satisfy each of the following conditions:

     (1) The limited partner must make a written demand upon the Partnership
  for the purchase of its limited partner units and the payment to the
  limited partner in cash of the fair market value of its limited partner
  units. The demand must be received by the Partnership within 30 days after
  the date on which notice of the approval of the merger proposal is mailed
  by the Partnership to the Partnership's limited partners. See "--
  Determination of fair market value" below.

     (2)  The demand must state the number of limited partner units in the
  Partnership held by the limited partner and must contain a statement of
  what that limited partner claims to be the fair market value of those
  limited partner units on the day before the announcement of the proposed
  merger. The statement of fair market value constitutes an offer by the
  limited partner to sell its limited partner units at that price.

     (3) The limited partner must not vote its limited partner units in favor
  of the merger proposal. Because a proxy which does not contain voting
  instructions will, unless revoked, be voted for the merger proposal, a
  limited partner who votes by proxy and who wishes to exercise dissenters'
  rights must vote against the merger proposal or abstain from voting on the
  merger proposal.

     (4) The limited partner must submit to the Partnership the certificate
  representing the limited partner units which the limited partner demands
  that the Partnership purchase, to be stamped or endorsed with a statement
  that the interest is a dissenting interest or to be exchanged for
  certificates of appropriate denomination so stamped or endorsed.

   Neither voting in person or by proxy against, abstaining from voting on or
failing to vote on the merger proposal will constitute a written demand upon
the Partnership for the purchase of limited partner units or the payment of
their fair market value in cash within the meaning of Article 7.6. The written
demand upon the Partnership for the purchase, for cash, at their fair market
value, of limited partner units in the Partnership must be in addition to and
separate from any proxy or vote.


                                      107
<PAGE>

   Only a holder of record of limited partner units issued and outstanding on
    , 1999, the record date fixed by McNeil Partners for the determination of
limited partners entitled to vote on the merger proposal, or an assignee of
record of such an interest, is entitled to exercise dissenters' rights for the
limited partner units registered in that limited partner's name.

   A limited partner who wishes to exercise dissenters' rights under Article
7.6 should mail or deliver a written demand, meeting the requirements of
Article 7.6, to: McNeil Partners, L.P., 13760 Noel Road, Suite 600, LB70,
Dallas, Texas 75240. A dissenting limited partner may not withdraw a demand for
payment unless the Partnership consents to that withdrawal. See "--Dissenters'
rights--Loss of status of dissenting interests."

   Limited partners exercising dissenters' rights should be aware that the fair
market value of their limited partner units as determined under Article 7.6
could be more, the same as or less than the aggregate amount they would receive
in the transaction if they did not exercise dissenters' rights. Limited
partners also should be aware that opinions of financial advisors are not
opinions as to fair market value under Article 7.6.

 Determination of fair market value

   The fair market value of a dissenting interest is determined as of the day
before the first announcement of the terms of the proposed merger, excluding
any appreciation or depreciation in fair market value as a consequence of the
proposed merger. The transaction was first announced on June 25, 1999. See "--
Background of the transaction--Background of the auction process." Therefore,
the fair market value of limited partner units in the Partnership would be
determined as of June 24, 1999.

   Within ten days after the date of approval of the merger proposal by the
required approval of the limited partners of the Partnership, the Partnership
must send a notice of that approval to the limited partners of the Partnership.
The notice must be accompanied by a copy of specified sections of Article 7.6
and a statement of the price determined by the Partnership to represent the
fair market value of the outstanding limited partner units in the Partnership.
The notice also must include a brief description of the procedure to be
followed if the limited partner desires to exercise the limited partner's
rights under those sections. The statement of the price determined by the
Partnership to represent the fair market value of the outstanding limited
partner units in the Partnership constitutes an offer by the Partnership to
purchase at that price any dissenting interests in the Partnership, unless
those interests lose their status as dissenting interests.

   If the Partnership and a dissenting limited partner agree that the
dissenting limited partner's interest is a dissenting interest and agree upon
the price to be paid for the dissenting interest, the dissenting limited
partner is entitled to the agreed price, together with interest at the legal
rate on judgments from the date of the effective time of the merger. All
agreements fixing the fair market value of any dissenting limited partner's
interest between the Partnership and that limited partner must be in writing
and filed in the records of the Partnership. Subject to fraudulent transfer
laws, payment of the fair market value for a dissenting interest must be made
within 30 days after the later of (1) agreement as to the amount of that
payment or (2) satisfaction of all statutory or contractual conditions to the
merger. As a condition to receiving this payment, the limited partner must
surrender the certificates evidencing its dissenting interests.

 Right to seek judicial determination

   A limited partner may ask a court to determine whether its interest is a
dissenting interest, or to determine the fair market value of the dissenting
interest, or both, if either:

  . the Partnership denies that the limited partner's interest in the
    Partnership is a dissenting interest, or

  . the Partnership and a dissenting limited partner fail to agree upon the
    fair market value of that limited partner's dissenting interest.


                                      108
<PAGE>

   If either or these two requirements are met, the limited partner, within
six months after the date on which notice of the approval of the merger by the
required vote of the limited partners was mailed to the limited partner, may
file a complaint in the superior court of the proper county praying the court
to determine whether the interest is a dissenting interest, or to determine
the fair market value of the dissenting interest, or both, or may intervene in
any action pending on such a complaint. The court may appoint one or more
impartial appraisers to determine the fair market value of a dissenting
interest.

   If the court determines that an interest is a dissenting interest, judgment
will be rendered against the Partnership for payment of the fair market value,
as determined by the court, of that dissenting interest, together with
interest at the legal rate on judgments from the effective time of the merger.
The judgment will be payable by the Partnership upon the endorsement and
delivery to the Partnership of the certificates representing the dissenting
interests. Any party may appeal from the judgment. The costs of the action,
including reasonable compensation for the appraisers, to be fixed by the
court, will be assessed or apportioned as the court considers equitable.
However, if the appraisal exceeds the price offered by the Partnership, the
Partnership will pay the costs, including, under some circumstances,
attorneys' fees and fees of expert witnesses. The Partnership may credit any
cash distributions made by the Partnership to a dissenting limited partner
after the effective time of the merger against any unpaid amounts remaining to
be paid by the Partnership for that dissenting interest. If litigation has
been instituted to test the sufficiency or regularity of the vote of the
limited partners in authorizing the merger, any judicial proceedings described
above will be suspended until final determination of that litigation.

 Loss of status of dissenting interests

   A limited partner will no longer be entitled to require the Partnership to
purchase a dissenting interest if:

  . the Partnership abandons the merger;

  . the limited partner transfers its interest prior to its submission for
    endorsement as described in paragraph (4) above in "--Dissenter's
    rights--Requirements for exercise of dissenters' rights;"

  . the dissenting limited partner and the Partnership do not agree upon the
    status of the interest of a dissenting partner or upon the purchase price
    of the dissenting interest and neither files a complaint nor intervenes
    in a pending action, as provided above in "--Dissenter's rights--Right to
    seek judicial determination," six months after the date on which notice
    of the approval of the merger by the required vote of the limited
    partners was mailed to the limited partner; or

  . the dissenting limited partner, with the consent of the Partnership,
    withdraws its demand for purchase of the dissenting interest.

   Failure to comply strictly with all of the procedures set forth in Article
7.6 will result in the loss of a limited partner's statutory dissenters'
rights. Consequently, any limited partner wishing to exercise dissenters'
rights is urged to consult legal counsel before attempting to exercise
dissenters' rights]

[For Funds IX-XII, XIV, XV: No dissenters' rights

   If limited partners owning more than 50% of [each class of] [the] limited
partner units in the Partnership vote for the merger proposal, this approval
will bind all limited partners in the Partnership. Limited partners in the
Partnership do not have any dissenters' rights or other rights of appraisal,
under the California Uniform Limited Partnership Act which governs the
Partnership, the Partnership's limited partnership agreement or otherwise, in
connection with the merger proposal. Therefore, dissenting limited partners do
not have the right

                                      109
<PAGE>

to have the fair market value of their limited partner units paid to them or
have their limited partner units appraised if they disapprove of the action of
the limited partners that voted for the merger proposal. Limited partners of
some of the other McNeil Partnerships do have such rights under applicable
California law.]

[For Fund XXVII: No appraisal rights

   If limited partners owning more than 50% of the limited partner units in the
Partnership vote for the merger proposal, this approval will bind all limited
partners in the Partnership. Limited partners in the Partnership do not have
any dissenters' rights or other rights of appraisal, under the Delaware Revised
Uniform Limited Partnership Act which governs the Partnership, the
Partnership's limited partnership agreement or otherwise, in connection with
the merger proposal. Therefore, dissenting limited partners do not have the
right to have the fair market value of their limited partner units paid to them
or have their limited partner units appraised if they disapprove of the action
of the limited partners that voted for the merger proposal. Limited partners of
some of the other McNeil Partnerships do have such rights under applicable
California law.]

Federal income tax consequences

   The following summary is a general discussion of some of the federal income
tax consequences that are relevant to limited partners of the Partnership. This
summary is based on the Internal Revenue Code of 1986, as amended, applicable
Treasury regulations under the Internal Revenue Code, administrative rulings,
practice and procedures and judicial authority, all as effective as of the date
of the transaction. All of the foregoing are subject to change or alternative
construction with possible retroactive effect, and any change or alternative
construction could affect the continuing accuracy of this summary. This summary
does not discuss all aspects of federal income taxation that may be relevant to
a particular limited partner in light of that limited partner's specific
circumstances or to limited partners subject to special treatment under the
federal income tax laws (for example, except where otherwise noted, foreign
persons, dealers in securities, banks, insurance companies and tax-exempt
organizations). In addition, except as otherwise expressly indicated, this
summary does not describe any aspect of state, local, foreign or other tax
laws.

   Each limited partner should consult its tax advisor as to the particular tax
consequences to that limited partner of participating in the transaction.

 Taxation of special distribution of cash

   The special distribution of cash, will not generally be subject to tax but
will reduce a limited partner's adjusted tax basis in its limited partner units
by the amount of the distribution (but not below zero). To the extent that the
distribution received by a limited partner exceeds that limited partner's
adjusted tax basis in all of its limited partner interests in the Partnership,
the excess will be taxable and will be treated as capital gain.

 Taxable gain or loss pursuant to the merger

   In general, a limited partner will recognize gain or loss on the conversion
of limited partner units into cash in the merger [additional disclosure for
Funds XX-XXVI: or on receipt of cash pursuant to the exercise of dissenters'
rights]. This gain or loss will be equal to the difference between the limited
partner's "amount realized" from the merger and the limited partner's adjusted
tax basis in the limited partner units converted. The "amount realized" will be
a sum equal to the amount of cash received by the limited partner for the
limited partner units in the merger, plus the amount of the Partnership's
liabilities allocable to the limited partner units (as determined under Section
752 of the Internal Revenue Code). In general, a limited partner's initial tax
basis in its limited partner units equals its cash investment in the
Partnership increased by that limited partner's share of the Partnership's
liabilities at the time the limited partner units were acquired.

                                      110
<PAGE>

  A limited partner's initial basis is generally increased by:

  . that limited partner's share of Partnership taxable income (including its
    allocable share of taxable income for the year in which the merger
    occurs) and

  . any increases in that limited partner's share of liabilities of the
    Partnership.

A limited partner's initial basis is generally decreased (but not below zero)
by:

  . that limited partner's share of Partnership cash distributions (including
    the special distribution of cash on the closing date of the transaction),

  . any decreases in that limited partner's share of liabilities of the
    Partnership,

  . that limited partner's share of losses of the Partnership (including an
    allocable share of taxable loss for the year in which the merger occurs),
    and

  . that limited partner's share of nondeductible expenditures of the
    Partnership that are not chargeable to capital.

  If a limited partner's adjusted tax basis is less than its share of the
Partnership's liabilities (for example, as a result of the effect of net loss
allocations and/or distributions exceeding the cost of its limited partner
units), that limited partner's gain will exceed the cash proceeds it receives
pursuant to the merger.

 Character of gain or loss recognized pursuant to the merger

   Except as described below, the gain or loss recognized by a limited partner
upon receipt of cash in the merger will generally be treated as a capital gain
or loss if the limited partner units were held by the limited partner as a
capital asset. Such capital gain or loss will be treated as long-term capital
gain or loss if the limited partner's holding period for the limited partner
units exceeds one year.

   If any portion of the amount realized by a limited partner is attributable
to "unrealized receivables," which includes recapture of certain depreciation
deductions previously taken, or "inventory items," as defined in Section 751 of
the Internal Revenue Code, then a portion of the limited partner's gain or loss
may be ordinary rather than capital. In addition, a limited partner will be
allocated its pro rata share of the Partnership's taxable income or loss for
the year in which the merger occurs, and therefore, will recognize ordinary
income in an amount equal to its allocable share of partnership ordinary
income. As described above, this allocation and any cash distributed by the
Partnership to the limited partner for the year in which the merger occurs will
affect the limited partner's tax basis in its limited partner units and,
therefore, the taxation of the special distribution of cash and the amount of
that limited partner's taxable gain or loss upon the conversion of its limited
partner units into cash in the merger.

 Passive activity losses

   Under Section 469 of the Internal Revenue Code, a non-corporate taxpayer or
personal service corporation generally can deduct "passive activity losses" in
any year only to the extent of the person's passive activity income for that
year. Closely-held corporations may not offset such losses against so-called
"portfolio" income. Substantially all post-1986 losses of limited partners from
the Partnership should be considered passive activity losses. Limited partners
may have "suspended" passive losses from the Partnership (i.e., post-1986 net
taxable losses in excess of statutorily permitted "phase-in" amounts which have
not been used to offset income from other passive activities) which may be
available to shelter gain from the special distribution or the merger in the
manner described below.

   Limited partners that recognize a gain on the conversion of their limited
partner units into cash in the merger will be entitled to use their current and
"suspended" passive activity losses (if any) from the Partnership and other
passive sources to offset that gain. Limited partners that recognize a loss on
the conversion of their limited partner units into cash in the merger will be
entitled to deduct that loss currently (subject to other applicable
limitations) against the sum of their passive activity income from the
Partnership for that year (if any) plus any passive activity income from other
sources for that year. The balance of any

                                      111
<PAGE>

"suspended" losses that were not otherwise utilized against passive activity
income as described in the two preceding sentences will no longer be suspended
and will therefore be deductible (subject to any other applicable limitations)
by that limited partner against any other income of that limited partner for
that year, regardless of the character of that income. Accordingly, limited
partners should consult their tax advisors concerning whether, and the extent
to which, they have available suspended passive activity losses from the
Partnership or other investments that may be used to offset gain from the
conversion of their limited partner units into cash in the merger.

   Information reporting, backup withholding and FIRPTA

   A limited partner whose limited partner units are converted into cash in the
merger must file an information statement with its federal income tax return
for the year in which the merger occurs which provides the information
specified in Treasury Regulation (S) 1.751-1(a)(3).

   Limited partners (other than tax-exempt persons, corporations and some
foreign persons) may be subject to 31% backup withholding unless they provide a
taxpayer identification number and certify that the taxpayer identification
number is correct or properly certify that they are awaiting a taxpayer
identification number. See the instructions to the letter of transmittal which
will be sent to you after the merger is completed.

   Gain realized by a foreign limited partner on the conversion of limited
partner units into cash in the merger will be subject to Federal income tax
under the Foreign Investment in Real Property Tax Act ("FIRPTA"). Under the
FIRPTA provisions of the Code, the transferee of an interest held by a foreign
person in a partnership which owns United States real property generally is
required to deduct and withhold 10% of the amount realized on the disposition.
Amounts withheld would be creditable against a foreign limited partner's
Federal income tax liability and, if in excess thereof, a refund could be
obtained from the Internal Revenue Service by filing a U.S. income tax return.
See the Instructions to the letter of transmittal which will be sent to you
after the merger is completed.

 Tax consequences to McNeil Partners

   McNeil Partners will generally not recognize gain or loss for United States
federal income tax purposes upon its transfer of assets to WXI/McN Realty
solely in exchange for membership interests in WXI/McN Realty. McNeil Partners
will have a tax basis in the membership interests in WXI/McN Realty equal to
McNeil Partners' adjusted basis in the transferred general partner interests
increased or decreased by any increase or decrease of its share of Partnership
liabilities. One of the reasons why McNeil Partners is exchanging its general
partner interests for membership interests in WXI/McN Realty is that a taxable
purchase of the general partner interests for cash would cause McNeil Partners
to recognize taxable gain in excess of any cash proceeds received, because of
the relief of partnership liabilities allocated to them.

   The transaction, as structured, will allow McNeil Partners to make the
contributions of its interests in the McNeil Partnerships and the assets of
McNeil Partners and McREMI being contributed to WXI/McN Realty on a tax-free
basis and to defer substantial tax liability that would be incurred if the
properties were disposed of in a taxable sale.

Anticipated accounting treatment

   The transaction will be accounted for under the "purchase" method of
accounting in accordance with generally accepted accounting principles.

Regulatory requirements

   Except for the filing of the certificate of merger with the Secretary of
State of the State of [for Funds IX-XII, XIV, XV, XX-XXVI: California pursuant
to the California Revised Limited Partnership Act] [for Fund XXVII: Delaware
pursuant to the Delaware Revised Uniform Limited Partnership Act], after the
approval and adoption of the merger proposal and compliance with federal and
state securities laws, neither the Partnership nor WXI/McN Realty is aware of
any material United States federal or state or foreign governmental regulatory
requirement necessary to be complied with or approval that must be obtained in
connection with the transaction.

                                  THE MEETING

Time, date and place of the meeting
   This Proxy Statement is being furnished to limited partners of the
Partnership in connection with the solicitation of proxies by and on behalf of
McNeil Partners, as general partner of the Partnership, for use at the meeting
of limited partners of the Partnership to be held at     , local time, on
 , 1999, at     , and at any adjournments or postponements of the meeting.

Matters to be considered at the meeting
   At the meeting, limited partners of the Partnership will be asked to
consider and vote on the merger proposal and to consider any other matters as
may properly come before the meeting.

   In addition, if a motion is made to adjourn or postpone the meeting, the
limited partners of the Partnership may also be asked to vote on the
adjournment or postponement of the meeting. The Master Agreement provides that
McNeil Partners will recommend the adjournment of the meeting for ten days if
on the date of the meeting the 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 for the merger proposal, will constitute
a sufficient number of votes to approve the merger proposal. However, if
limited partners holding greater than a majority of the outstanding limited
partner units in the Partnership have indicated their intention to vote
against, and have submitted duly executed proxies voting against, the merger
proposal, the Master Agreement does not require McNeil Partners to recommend
adjournment of the meeting. See "The Master Agreement--Limited partner
meetings; proxy material."

Recommendations of the McNeil Investors board of directors

   The McNeil Investors board of directors, based upon the recommendation of
the special committee and the Stanger & Co. opinions, has unanimously
determined that the merger proposal is fair to and in the best interests of the
Partnership and its limited partners. Accordingly, the McNeil Investors board
of directors has unanimously approved the merger proposal and unanimously
recommends that the limited partners of the Partnership vote for the merger
proposal.

Record date; voting power
   McNeil Partners has fixed the close of business on    , 1999, as the record
date for determination of the limited partners entitled to notice of and to
vote at the meeting and any adjournment or postponement of the meeting. Only
holders of record of limited partner units at the close of business on    ,
1999, are entitled to notice of and to vote at the meeting. As of the record
date, there were    limited partner units in the Partnership issued and
outstanding and held of record by approximately    holders of record. Holders
of record of limited partner units in the Partnership are entitled to one vote
for each unit that they hold on the merger proposal and any other matter that
may properly come before the meeting. [Additional disclosure for Funds XXI-
XXIII: Holders of current income units and holders of growth/shelter units will
vote separately on the merger proposal.]

Quorum
   The necessary quorum for the transaction of business at the meeting is the
presence in person or by proxy of limited partners holding [for all except
Funds XXI-XXIII: a majority of the limited partner units] [for Funds XXI-XXIII:
a majority of each class of limited partner units] in the Partnership
outstanding on the record date. For purposes of determining the presence of a
quorum, abstentions will be counted by McNeil Partners as not present at the
meeting.

   In the event that there are insufficient votes present at the meeting to
constitute a quorum, and proxies and votes against the proposals represent
fewer than [for all except Funds XXI-XXIII: 50% of the limited partner units]
[for Funds XXI-XXIII: 50% of each class of limited partner units], the limited
partner units for which proxies have been received may be voted to adjourn the
meeting to a later date to permit the further solicitation of proxies. Notice
of the adjourned meeting need not be given if the time and place of the
adjourned meeting is announced at the meeting, or the adjourned meeting, and
the adjournment is for not more than thirty days from the date of the original
meeting and no new record date is set.

                                      113
<PAGE>

Vote required

   The affirmative vote of limited partners holding greater than [for all
except Funds XXI-XXIII: 50% of the limited partner units] [for Funds XXI-XXIII:
50% of each class of limited partner units] in the Partnership outstanding on
the record date is required to approve the merger proposal.

   Limited partners of the Partnership are urged to complete, date, sign and
promptly return the enclosed proxy. All properly executed proxies received by
McNeil Partners prior to the meeting that are not revoked will be voted at the
meeting in accordance with the instructions indicated on the proxies. If a
limited partner fails to return a proxy, the effect will be the same as a vote
against the merger proposal. If a limited partner marks "ABSTAIN" on the proxy
with respect to the merger proposal, the effect will be the same as a vote
against the merger proposal. If a limited partner returns the proxy but does
not give instructions on the proxy, that limited partner's limited partner
units will be voted for the merger proposal.

Ownership of limited partner units in the Partnership

   [Additional disclosure for Funds IX-XI, XIV, XV, XX, XXV-XXVII: As of the
record date, McNeil Partners and some of its affiliates, other than the
Partnership, beneficially owned an aggregate of    limited partner units in the
Partnership, representing in the aggregate approximately  % of the limited
partner units outstanding on the record date. McNeil Partners and these
affiliates intend to vote all of the limited partner units beneficially owned
by them in the Partnership for the merger proposal.] [Additional disclosure for
Fund XXIII: As of the record date, McNeil Partners beneficially owned an
aggregate of      growth/shelter units in the Partnership, representing in the
aggregate approximately   % of the growth/shelter units outstanding on the
record date. McNeil Partners intends to vote all of the limited partner units
beneficially owned by it in the Partnership for the merger proposal.]

   As of the record date, no individual or group as defined in Section 13(d)(3)
of the Securities Exchange Act, except the individuals and groups, if any, set
forth in "Related Security Holder Matters--Principal holders of limited partner
units," was known by the Partnership to own more than 5% of the limited partner
units in the Partnership.

Solicitation of proxies

   Proxies are being solicited by and on behalf of McNeil Partners, as general
partner of the Partnership. The Partnership will initially pay the costs of
soliciting proxies with respect to the Partnership. In addition to solicitation
by mail, McNeil Partners and the officers, directors and employees of McNeil
Investors may solicit proxies by telephone, telegram or otherwise. The
directors, officers and employees of McNeil Investors will not receive
compensation for that solicitation but may receive reimbursement by the
Partnership for out-of-pocket expenses incurred in connection with that
solicitation. The Partnership will request that brokerage firms, fiduciaries
and other custodians forward copies of this Proxy Statement and the enclosed
form of proxy to the beneficial owners of limited partner units in the
Partnership held of record by them, and the Partnership will reimburse those
brokerage firms, fiduciaries and other custodians for their reasonable expenses
incurred in forwarding such material. The Partnership has retained persons to
aid it in the solicitation. McNeil Partners anticipates that fees plus expenses
of these persons will be approximately $     in the aggregate for all of the
McNeil Partnerships (approximately $    of which is attributable to the
Partnership). McNeil Partners anticipates that the total cost of soliciting
proxies on behalf of all of the McNeil Partnerships will be approximately $
(approximately $     of which is attributable to the Partnership), of which
approximately $     of which has been incurred to date (approximately $    of
which is attributable to the Partnership). See "Special Factors--Fees and
expenses relating to the transaction."

   The matters to be considered at the meeting are of great importance to the
Partnership and to the limited partners of the Partnership. Please read and
carefully consider the information presented in this Proxy Statement and the
other documents to which we have referred you and complete, date, sign and
promptly return the enclosed proxy. Completed proxies should be returned as
soon as possible. You may return your proxy as follows:

List of limited partners of the Partnership

   Under the federal securities laws, a limited partner of the Partnership who
is entitled to vote at the meeting may request in writing a list of the other
limited partners in the Partnership entitled to vote at the meeting to enable
the requesting limited partner to mail soliciting materials to the other
limited partners in the Partnership. Alternatively, a limited partner of the
Partnership who is entitled to vote at the meeting may request that the
Partnership mail copies of any proxy statement, form of proxy or other
soliciting material furnished by the requesting limited partner to the other
limited partners of the Partnership. The requesting limited partner must
reimburse the Partnership for the Partnership's reasonable expenses incurred in
connection with performing these services. Any requests referred to in this
paragraph should be made in writing to: McNeil Partners, L.P., P.O. Box 80039,
Dallas, Texas, 75380.

   At the time of making the request, the requesting limited partner must, if
its limited partner units are held through a nominee, provide the Partnership
with a statement from the nominee or other independent third party confirming
the limited partner's beneficial ownership. In addition, the requesting limited
partner must provide the Partnership with an affidavit or similar document
that:

  . identifies the proposal that will be the subject of the limited partner's
    solicitation;

  . states that the limited partner will not use the list for any purpose
    other than to solicit limited partners of the Partnership with respect to
    the same action for which the Partnership is soliciting votes; and

  . states that the limited partner will not disclose the information
    provided to it to any person other than a beneficial owner for whom the
    request was made and an employee or agent to the extent necessary to
    effectuate the communication or solicitation.

   Upon termination of any solicitation by the requesting limited partner, the
requesting limited partner must return to the Partnership, without keeping any
copies, the information provided by the Partnership and any information derived
from that information. A limited partner is only entitled to the foregoing
information with respect to a McNeil Partnership in which the limited partner
holds limited partner units.

                                      115

   The limited partnership agreement of the Partnership provides that a limited
partner of the Partnership has the right, upon reasonable request, to inspect
and copy the list of limited partners of that Partnership. The limited
partnership agreement of the Partnership also provides that limited partners in
the Partnership may inspect and copy, at their own expense, the list of limited
partners in the Partnership. [Additional disclosure for Funds XX-XXVI: The
California Revised Limited Partnership Act also permits a limited partner of
the Partnership to request a list of other limited partners of that
Partnership. The Partnership must deliver the list of limited partners to the
requesting limited partner at the Partnership's expense.]

                              THE MASTER AGREEMENT

   This section of the Proxy Statement describes various aspects of the
proposed transaction, including material provisions of the Master Agreement.
The description of the Master Agreement contained in this Proxy Statement does
not purport to be complete and is qualified in its entirety by reference to the
Master Agreement, a copy of which is attached to this Proxy Statement as
Appendix A, and which is incorporated in this Proxy Statement by reference. All
limited partners in the McNeil Partnerships are urged to read carefully the
Master Agreement in its entirety.

Parties to the Master Agreement

   For a description of the parties to the transaction, see "Summary--Parties
to the transaction."

Structure of the transaction

   For an overview of the structure of the transaction and the steps involved
in the transaction, see "Summary--Structure of the transaction." These steps
are described in more detail below in "--The mergers" and "--The
contributions."

Closing of the transaction

   The closing of the mergers and the other transactions contemplated by the
Master Agreement will take place at a time and on a date which will be no later
than five business days after the later of:

  . satisfaction or waiver of all conditions precedent to the closing of the
    transaction set forth in the Master Agreement (see "--Conditions to
    closing") and

  . three full business days following the date of WXI/McN Realty's receipt
    of the Pre-Closing Removal Notice described in "--Conditions to closing--
    Removal notices" with respect to one or more McNeil Partnerships,

unless another time or date is agreed to by Sellers and WXI/McN Realty. See "--
Conditions to closing--Removal notices."

Aggregate consideration

 Allocation of aggregate consideration

   The aggregate consideration in the transaction, including all outstanding
mortgage debt of the McNeil Partnerships, is $644,439,803. The aggregate
consideration in the transaction has been allocated by Stanger & Co. as
described in "Special Factors--Opinions and reports of financial advisors--
Allocation analysis and opinions of Stanger & Co.--Stanger & Co. allocation
analysis." The individual allocations of the aggregate consideration are set
forth in Table 2.

 Prepayment and assumption of mortgage debt

   The aggregate consideration in the transaction includes an amount equal to
the outstanding mortgage debt of the McNeil Partnerships. At the effective time
of the mergers, all outstanding mortgage debt of the participating McNeil
Partnerships will either be prepaid by WXI/McN Realty or will remain
outstanding following the effective time of the mergers until its expiration or
prepayment. Some outstanding mortgage debt on the properties will be prepaid at
the effective time if the McNeil Partnerships which own those properties are
participating McNeil Partnerships, and WXI/McN Realty will pay all prepayment
fees with respect to the prepayment of that mortgage debt. Other mortgage debt
will be repaid at the effective time of the mergers if the McNeil Partnership
which owns those properties is a participating McNeil Partnership, and that
McNeil Partnership will pay the respective prepayment fees related to the
prepayment of that mortgage debt. The

                                      117
<PAGE>

mortgage debt secured by the remainder of the properties will remain
outstanding at and after the effective time of the mergers until its expiration
or prepayment. WXI/McN Realty will pay one-half of the assumption fees, up to a
maximum of $250,000, related to the indirect assumption by WXI/McN Realty of
the mortgage debt that is not being prepaid at the effective time. The
respective participating McNeil Partnerships which own the properties that
secure the assumed mortgage debt will pay all remaining assumption fees.

The mergers

   WXI/McN Realty will acquire by merger all of the participating McNeil
Partnerships except the Affiliated McNeil Partnerships. WXI/McN Realty will
acquire the Affiliated McNeil Partnerships in the manner described below in "--
The contributions." For each participating McNeil Partnership other than the
Affiliated McNeil Partnerships, a separate newly formed subsidiary limited
partnership of WXI/McN Realty will be merged with and into that participating
McNeil Partnership, with the participating McNeil Partnership surviving as a
subsidiary limited partnership of WXI/McN Realty. See "Summary--Structure of
the transaction;" Figure 7 depicts the mergers, assuming all McNeil
Partnerships participate in the transaction, and Figure 8 depicts the ownership
of the McNeil Partnerships following the mergers.

   The merger of each participating McNeil Partnership will become effective at
the time on the closing date of the transaction specified in the merger
certificate for that participating McNeil Partnership or at a later time agreed
upon by the parties to the Master Agreement and set forth in each of the merger
certificates for the participating McNeil Partnerships.

   Limited partners of each of the participating McNeil Partnerships, other
than the Affiliated McNeil Partnerships, will receive cash consideration in the
transaction. The aggregate amount to be received in the transaction by limited
partners of the participating McNeil Partnerships consists of two components--
the merger consideration and a special cash distribution. See "The mergers--
Merger consideration" and "--The mergers--Special distribution of positive net
working capital balance."

 Merger consideration

   The first component of the aggregate amount to be received by limited
partners of each of the participating McNeil Partnerships, other than the
Affiliated McNeil Partnerships, is the merger consideration. At the effective
time, as a result of the mergers, each limited partner unit in a participating
McNeil Partnership other than the Affiliated McNeil Partnerships will be
converted into the right to receive the amount in cash set forth in the column
"Per Unit Merger Consideration" in Table 2 opposite the name of that McNeil
Partnership. The merger consideration is equal to the amount of the aggregate
consideration in the transaction allocated by Stanger & Co. to the limited
partner units in that McNeil Partnership. However, if the modified net working
capital balance for a McNeil Partnership determined as of the closing date of
the transaction in accordance with the Master Agreement is a negative number,
the per unit merger consideration to be received by each class of limited
partners of that McNeil Partnership will be reduced by the per unit amount of
the negative modified net working capital allocable to that class based on the
provisions in that McNeil Partnership's limited partnership agreement governing
distributions of surplus cash. See "--The mergers--Special distribution of
positive net working capital balance."

   At the effective time, each limited partner unit in a participating McNeil
Partnership will no longer be outstanding and will automatically be cancelled
and retired and will cease to exist and the limited partner that holds that
limited partner unit will cease to have any rights with respect to that limited
partner unit, except the right to receive the per unit merger consideration and
the portion of the special distribution, if any, in respect of that
participating McNeil Partnership, in each case, without interest, to which that
limited partner unit is entitled.

 Exchange of certificates

   The Master Agreement provides that at the effective time of the mergers,
WXI/McN Realty will deposit with a payment agent cash in an aggregate amount
equal to the sum of the amounts set forth in the column

                                      118
<PAGE>

"LP Allocation Amount" in Table 2 opposite the name of each of the
participating McNeil Partnerships other than the Affiliated McNeil
Partnerships. However, if the modified net working capital balance for a McNeil
Partnership determined as of the closing date of the transaction in accordance
with the Master Agreement is a negative number, the "LP Allocation Amount" for
each class of limited partner units in that McNeil Partnership will be reduced
by the portion of the negative modified net working capital balance allocable
to that class based on the provisions in that McNeil Partnership's limited
partnership agreement governing distributions of surplus cash, except that the
general partner of that McNeil Partnership will not receive any part of the
special distribution. See "The mergers--Special distribution of positive net
working capital balance."

   Immediately following the effective time of the mergers, the payment agent
will mail to each limited partner a letter of transmittal and instructions for
surrendering that limited partner's certificates in exchange for the per unit
merger consideration to which that holder is entitled.

   Upon surrender of its certificates, a limited partner will be entitled to
receive a check in an amount equal to the product obtained by multiplying the
number of limited partner units held by that limited partner by the per unit
merger consideration set forth in Table 2 opposite the name of that McNeil
Partnership. Any certificates surrendered to the payment agent as described
above will be cancelled. Until surrendered as described above, each certificate
will be deemed at and after the effective time of the mergers to represent only
the right to receive upon that certificate's surrender the per unit merger
consideration.

   In the event of a transfer of ownership of limited partner units in a McNeil
Partnership which is not registered in the transfer records of that McNeil
Partnership, payment of the per unit merger consideration which the limited
partner that holds those limited partner units has the right to receive may be
made to a transferee if the certificate representing those limited partner
units is presented to the payment agent accompanied by all documentation
required to evidence and effect that transfer.

   In the event that any certificate has been lost, stolen or destroyed, the
limited partner that holds that certificate will be required to make an
affidavit that the certificate has been lost, stolen or destroyed. The payment
agent will then issue in exchange for that affidavit the per unit merger
consideration to which the limited partner that holds that certificate has the
right to receive. Unless WXI/McN Realty determines otherwise, the payment agent
will require the delivery of a suitable bond or indemnity in a form acceptable
to WXI/McN Realty.

   All merger consideration paid upon the surrender or exchange of limited
partner units in the participating McNeil Partnerships will be deemed to have
been paid in full satisfaction of the rights pertaining to those limited
partner units. The surviving limited partnership of each of the mergers will
continue to have an obligation following the effective time of the mergers to
pay distributions with a record date prior to the effective time which may have
been declared by a participating McNeil Partnership on limited partner units in
that participating McNeil Partnership and which remain unpaid as of the
effective time and to distribute to the former limited partners of each
participating McNeil Partnership the special distribution of that participating
McNeil Partnership as described below in "--The mergers--Special distribution
of positive net working capital balance." After the effective time of the
mergers, no further registration of transfers of limited partner units in the
participating McNeil Partnerships outstanding immediately prior to the
effective time will be made on the books of the surviving limited partnerships.
If after the effective time certificates are presented to the surviving
partnerships for any reason, these certificates will be canceled and exchanged
for the per unit merger consideration as provided above.

   The McNeil Partnerships will pay all charges and expenses relating to the
mergers, and WXI/McN Realty will reimburse the McNeil Partnerships, on the
closing date and immediately prior to the special distribution contemplated
below under "--The mergers--Special distribution of positive net working
capital balance," in an amount in cash equal to one-half of the amount of the
expenses relating to the payment agent. None of the payment agent, WXI/McN
Realty, WXI/McN Realty's subsidiaries, the Sellers nor any of their respective
affiliates will be liable to any limited partner of a participating McNeil
Partnership for any merger consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

                                      119
<PAGE>

 Special distribution of positive net working capital balance

   The second component of the aggregate amount to be received by limited
partners of each of the participating McNeil Partnerships, including the
Affiliated McNeil Partnerships, is the special cash distribution. The Master
Agreement provides that on the closing date of the transaction and immediately
prior to the effective time of the mergers, a special cash distribution will be
declared to the limited partners of each participating McNeil Partnership. The
amount of the special distribution will be calculated in accordance with the
Master Agreement and is based upon a modified net working capital balance of
the McNeil Partnership as of the closing date. The special distribution will be
made in accordance with the provisions of that participating McNeil
Partnership's limited partnership agreement governing distributions of surplus
cash, except that the general partner of that McNeil Partnership will not
receive any part of the special distribution.

   If on the closing date of the transaction and immediately prior to the
effective time of the mergers, the modified net working capital balance of a
participating McNeil Partnership as of that date, calculated in accordance with
the Master Agreement for that participating McNeil Partnership is a negative
number, the "LP Allocation Amount" for each class of limited partner units in
that McNeil Partnership will be reduced by the portion of the negative modified
net working capital balance allocable to that class based on the provisions in
that McNeil Partnership's limited partnership agreement governing distributions
of surplus cash. As a result, the per unit merger consideration to be received
by each class of limited partners of that McNeil Partnership will be reduced by
the per unit amount of the negative modified net working capital balance
allocable to that class.

The contributions

 Contributions to McNeil Partners by the other McNeil Affiliates

   The Master Agreement provides that prior to the effective time of the
mergers and following the holding of all of the limited partner meetings of the
McNeil Partnerships (see "--Material covenants--Limited partner meetings; proxy

  Partners;

     (2) if Fairfax is a participating McNeil Partnership, Robert A. McNeil,
  the general partner of Fairfax and a limited partner of Fairfax, will
  contribute transfer and assign to McNeil Partners or an affiliate of McNeil

  for limited partner interests in McNeil Partners;

     (3) if McNeil Summerhill I, L.P. is a participating McNeil Partnership,
  McNeil Summerhill, Inc., the general partner of McNeil Summerhill I, L.P.,
  will contribute, transfer and assign to McNeil Partners or an affiliate of

  McNeil Summerhill I, L.P., will contribute, transfer and assign to McNeil
  Partners all of the limited partner units in McNeil Summerhill I, L.P., in
  each case, in exchange for limited partner interests in McNeil Partners;

     (4) McREMI will contribute, transfer and assign to McNeil Partners
  certain assets of McREMI related to the participating McNeil Partnerships
  in exchange for limited partner interests in McNeil Partners.

   As of the date of this Proxy Statement, First Associated Management, Inc., a
Texas corporation and the surviving corporation in the merger between First

                                      120
<PAGE>

First Associated Management, Inc. will resign as a general partner of Regency

McREMI following the contributions, assuming all McNeil Partnerships
participate in the transaction.

 Replacement of general partner

   Following the contributions to McNeil Partners described in paragraphs (1)
through (4) above under "--The contributions--Contributions to McNeil Partners
by the other McNeil Affiliates" and immediately prior to the effective time of
the mergers, the Master Agreement provides that McNeil Partners will
contribute, transfer and assign to the applicable subsidiaries of WXI/McN
Realty, at the direction of WXI/McN Realty, in the case of each participating
McNeil Partnership, all of the general partner interests owned by McNeil
Partners in that participating McNeil Partnership and certain assets of McNeil
Partners related to that participating McNeil Partnership.

   Following these contributions, transfers and assignments, in the case of
each participating McNeil Partnership, the WXI/McN Realty subsidiary to which
those contributions, transfers and assignments have been made will be appointed
as the successor general partner of that participating McNeil Partnership. In
consideration for these contributions, transfers and assignments by McNeil
Partners, WXI/McN Realty will issue membership interests in WXI/McN Realty to
McNeil Partners. For each participating McNeil Partnership, McNeil Partners
will receive credit for a capital contribution to WXI/McN Realty in an amount
equal to the MPLP Allocation Amount set forth in Table 2 opposite the name of
that participating McNeil Partnership.

   See "Summary--Structure of the transaction." Figure 5 depicts, among other
things, the replacement of the general partner of the McNeil Partnership,
assuming all McNeil Partnerships participate in the transaction.


 Other contributions by McNeil Partners to WXI/McN Realty and WXI/McN Realty's
 subsidiaries

   Following the contributions to McNeil Partners described above under "--The
contributions--Contributions to McNeil Partners by the other McNeil Affiliates"
and immediately prior to the effective time of the mergers, the Master

  . agree in writing or otherwise to take any of the foregoing actions or

 Limited partner meetings; proxy material

   Sellers have agreed to prepare, and in the case of each of the public McNeil
Partnerships, file with the SEC, as soon as practicable after the date of the
Master Agreement but in any event not later than August 31, 1999, this Proxy
Statement. The August 31 deadline for preparing, and in the case of each of the
public McNeil Partnerships filing with the SEC, may be extended by Sellers
subject to the approval of WXI/McN Realty, which approval shall not be
unreasonably withheld or delayed. In addition, if required by law, Sellers and
any person that may be deemed an affiliate of any public McNeil Partnership
have agreed to prepare and file concurrently with the filing of this Proxy
Statement for the public McNeil Partnerships the Schedule 13E-3 with the SEC
with respect to each public McNeil Partnership. WXI/McN Realty has agreed, upon
request of Sellers, to furnish Sellers with any information concerning itself,
WXI/McN Realty's managing member and Whitehall as may be required by law or by
any governmental entity in connection with this Proxy Statement, any Schedule
13E-3 or any other statement, filing, notice or application made by or on
behalf of WXI/McN Realty to any third party or any governmental entity or both
in connection with the merger proposal.

   The Master Agreement provides that each McNeil Partnership other than the
Affiliated McNeil Partnerships will, as soon as practicable, 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
for the purpose of obtaining requisite approval by its limited partners of that
McNeil Partnership of the merger proposal. See "The Meeting." The Master
Agreement provides that the meeting of the limited partners of each McNeil
Partnership will be held at the earliest practicable date following the date
this Proxy Statement is mailed to the limited partners of that McNeil
Partnership. The Master Agreement also provides that unless otherwise
prohibited by law, each McNeil Partnership and its general partner are required
to hold the limited partner meeting with respect to that McNeil Partnership,
regardless of whether the general partner of that McNeil Partnership has
withdrawn, amended or modified its recommendation that the limited partners of
that McNeil Partnership approve the merger proposal, unless that McNeil
Partnership has become an excluded McNeil Partnership pursuant to the terms of
the Master Agreement. See "--Termination of the Master Agreement--Right to
terminate the Master Agreement with respect to one or more McNeil
Partnerships."

   The Master Agreement also provides that the general partner of each of the
McNeil Partnerships, other than the Affiliated McNeil Partnerships, will
recommend to the limited partners of that McNeil Partnership approval of the
merger proposal. See "Special Factors--Recommendations of the special committee
and the McNeil Investors board of directors; fairness of the transaction" and
"Special Factors--Position of McNeil Partners and Robert A. McNeil regarding
the transaction." Notwithstanding the foregoing, prior to the limited partner
meeting for a McNeil Partnership or any adjournment of the limited partner
meeting, the recommendation of the general partner of that McNeil Partnership
may be withdrawn, amended or modified as a result of the commencement or
receipt of a proposal constituting a superior acquisition proposal (as defined
below under "--Material covenants--No solicitation by Sellers") with respect to
that McNeil Partnership, but only to the extent described below in "--Material
covenants--No solicitation by Sellers."

   The Master Agreement further provides that if on the date of the limited
partner meeting for a McNeil Partnership, that McNeil 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 the
Master Agreement, will constitute a sufficient number of votes to adopt the
Master Agreement and limited partners holding greater than a majority of the
outstanding limited partner units in that McNeil Partnership have not indicated
their intention to vote against, and have not submitted duly executed proxies
voting against, the adoption of the Master Agreement, then that McNeil
Partnership and its general partner are required by the Master Agreement to
recommend the adjournment of its limited partner meeting until the date ten
days after the originally scheduled date of that limited partner meeting.

                                      125

 No solicitation by Sellers

   Prior to the effective time of the mergers, each Seller has agreed that:

  . it will 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 (as defined below)
    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;

  . it will immediately cease and cause to be terminated any existing
    activities, discussions or negotiations with any parties conducted prior
    to the date of the Master Agreement with respect to any acquisition
    proposal and will 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 by it as described in "--Material covenants--No
    solicitation by Sellers;" and

  . it will notify WXI/McN Realty immediately if it receives any inquiries or
    proposals, or any requests for information described in the first bullet
    point above, or if any negotiations or discussions described in the
    second bullet point above are sought to be initiated or continued with
    it.

   As used in this Proxy Statement, "acquisition proposal" means any proposal
or offer with respect to a merger, acquisition, purchase, tender offer,
exchange offer, consolidation or similar transaction involving all or any
significant portion of the assets (whether owned directly or indirectly) or
equity securities of, one or more of Sellers, other than the transactions with
WXI/McN Realty contemplated by the Master Agreement and the other transaction
documents.

   As used in this Proxy Statement, "superior acquisition proposal" means a
bona fide acquisition proposal made by a third party for one or more of the
McNeil Partnerships which the general partner of that McNeil Partnership
determines in good faith to be more favorable to the limited partners of that
McNeil Partnership from a financial point of view than the merger proposal, and
which the general partner of that McNeil Partnership determines in good faith
is reasonably likely to be consummated.

   Notwithstanding the foregoing, the general partner of any McNeil Partnership
may furnish information to or enter into discussions or negotiations with, any
person that makes an unsolicited acquisition proposal for that 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
that general partner to comply with its duties to its limited partners imposed
by law; (b) prior to furnishing that information to, or entering into
discussions or negotiations with, that person, that general partner provides
written notice to WXI/McN Realty to the effect that it is furnishing
information to, or entering into discussions with, that person; (c) subject to
the following clause (d), that general partner keeps WXI/McN Realty informed of
the status but not the terms of any such discussions or negotiations with that
person; and (d) that McNeil Partnership does not enter into a binding written
agreement with respect to an acquisition proposal without providing WXI/McN
Realty with at least four business days prior notice of its intent to do so,
which notice shall disclose the material terms of the acquisition proposal. In
addition, the general partner of any McNeil Partnership may take and disclose
to the limited partners of that McNeil Partnership a position, with respect to
that McNeil Partnership, contemplated by the tender offer rules--Rule 14d-9,
"Solicitation/Recommendation Statements with Respect to Certain Tender Offers,"
and Rule 14e-2, "Position of Subject Company with Respect to a Tender Offer,"
under the Securities Exchange Act--with regard to an acquisition proposal for
that McNeil Partnership.

   The general partner of any McNeil Partnership may approve and recommend a
superior acquisition proposal and, in connection with such approval and
recommendation, withdraw or modify its approval or

                                      126
<PAGE>

recommendation of the merger proposal, prior to the approval by the limited
partners of that McNeil Partnership at the limited partner meeting or any
adjournment of the limited partner meeting of that McNeil Partnership of the
merger proposal.

   The Master Agreement also provides that 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 that 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 under the Securities Exchange Act, will not constitute a
violation of any of the foregoing paragraphs, provided that such disclosure
states that no action will be taken by that general partner with respect to the
withdrawal of its recommendation of the transactions contemplated by the Master
Agreement or the approval or recommendation of any acquisition proposal except
in accordance with the foregoing paragraphs.

 Reasonable best efforts

   The Master Agreement provides that Sellers and WXI/McN Realty will use their
reasonable best efforts, without the payment of any consideration for those
efforts 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
the Master Agreement and the other transaction documents.

   In addition, the Master Agreement provides that Sellers will use their
reasonable best efforts:

  . to cooperate with WXI/McN Realty in assisting WXI/McN Realty to obtain
    new financing in connection with the mergers and the other transactions
    contemplated by the Master Agreement and the other transaction documents;

  . to obtain from Stanger & Co. the Stanger & Co. opinions, the Stanger &
    Co. allocation analysis and, if requested, the appraisals (see "Special
    Factors--Opinions and reports of financial advisors--Allocation analysis
    and opinions of Stanger & Co."), and to obtain from Eastdil Realty
    Company the Eastdil Realty Company opinions (see "Special Factors--
    Opinions and reports of financial advisors--Eastdil Realty Company
    opinions"), in each case on or prior to the date on which this Proxy
    Statement is mailed to the limited partners of the McNeil Partnerships;
    and

  . to obtain the consent and estoppel certificates and the consents
    specified in section 8.2(d) of the Master Agreement (see paragraphs (5)
    and (6) under "--Conditions to closing--Conditions to WXI/McN Realty's
    obligations to close"), estoppels from commercial tenants and ground
    lessors and, if requested in writing by WXI/McN Realty, subordination,
    non-disturbance and attornment agreements.

   Sellers also have agreed to use their reasonable efforts to cooperate with
WXI/McN Realty in assisting WXI/McN Realty in its efforts to correct or satisfy
specified items relating to title to certain of the properties.

 Replacement indemnification agreements

   McNeil Partners and McNeil Investors currently are parties to existing
indemnification obligations or agreements relating to mortgage debt on some of
the McNeil Partnership properties and agreements with lenders or affiliates of
lenders of some mortgage debt on some of the properties. Under these existing
indemnification obligations and agreements, McNeil Partners or McNeil Investors
or both have assumed liability on behalf of one or more McNeil Partnerships or
their subsidiaries for exceptions to non-recourse provisions contained in that
mortgage debt.

   In the Master Agreement, WXI/McN Realty has agreed to deliver at the closing
of the transaction any replacement agreements or other documents necessary to
assume all of the Sellers' obligations (other than the participating McNeil
Partnerships) and their affiliates as indemnitor under all of those existing
indemnification

                                      127
<PAGE>

obligations or agreements, and to use its reasonable efforts to ensure that
those replacement agreements and other documents delivered at the closing
release Sellers (other than the participating McNeil Partnerships) and their
affiliates from all of Sellers' (other than the participating McNeil
Partnerships) and their affiliates' obligations under those existing
indemnification obligations and agreements. See "Special Factors--Effects of
the transaction--Benefits and detriments to the McNeil Affiliates."

   In addition, WXI/McN Realty has agreed in the Master Agreement 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 those existing indemnification obligations and
agreements after the closing date of the transaction.

   McNeil Partners, to the extent that the obligations of McNeil Partners or
McNeil Investors as an indemnitor under any of those existing indemnification
obligations or agreements are not discharged, has agreed in the Master
Agreement to indemnify and hold harmless WXI/McN Realty from any and all
obligations incurred by McNeil Partners or McNeil Investors as an indenitor
under any of those existing indemnification obligations or agreements prior to
the closing date of the transaction.

 Reimbursable proposals

   The Master Agreement provides that during the period from June 24, 1999 to
the closing date of the transaction, Sellers have the option of presenting to
WXI/McN Realty for approval, which approval shall not be unreasonably withheld
or delayed, one or more proposals for capital expenditures, tenant inducements
(e.g., free rent, other cash-equivalent inducements and out-of-pocket
inducements) or commissions, specifying the budgeted amounts for these
proposals, that one or more McNeil Partnerships are contemplating in connection
with one or more new commercial leases or the lease of additional space to an
existing commercial tenant.

   To the extent that any one or more of these proposals with respect to a
participating McNeil Partnership have been approved by WXI/McN Realty, WXI/McN
Realty will make a cash contribution to that participating McNeil Partnership
prior to the special distribution described in "--The mergers--Special
distribution of positive net working capital balance" in an aggregate amount
equal to the sum of the "capital expenditure reimbursement amount," calculated
as described below, for each proposal approved by WXI/McN Realty with respect
to that participating McNeil Partnership.

   For any proposal that has been completed as of the estimated closing date of
the transaction, the "capital expenditure reimbursement amount" for that
proposal will equal the product determined by multiplying:

     (1) an amount equal to the lesser of (a) the aggregate amount expended
  or incurred through to the closing date of the transaction in connection
  with that proposal and (b) the total budgeted amounts of that proposal, by

     (2) a fraction, the numerator of which is the number of months,
  including any fraction of a month, in the period beginning on the estimated
  closing date of the transaction 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. In no event will this fraction be greater than one.

   For any proposal that has not been completed as of the estimated closing
date of the transaction, the "capital expenditure reimbursement amount" for
that proposal will equal the product determined by multiplying:

     (1) the difference determined by subtracting

         (a) the excess, if any, of (x) the sum of the aggregate amount
    expended or incurred through to the closing date of the transaction in
    connection with that proposal and the estimated additional amount
    reasonably and in good faith jointly determined by WXI/McN Realty and
    McNeil Partners

                                      128
<PAGE>

    required to be expended or incurred following the estimated closing
    date of the transaction to complete that proposal over (y) the total
    budgeted amounts for that proposal, from

         (b) the aggregate amount expended or incurred through to the
    closing date of the transaction in connection with that proposal, by

     (2) a fraction, the numerator of which is the number of months,
  including any fraction of a month, in the period beginning on the estimated
  closing date of the transaction 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. In no event will this fraction be greater than one.

   The capital expenditure reimbursement amounts with respect to a
participating McNeil Partnership will be taken into account in the
determination of the modified net working capital balance and special
distribution of that participating McNeil Partnership. See "--The mergers--
Special distribution of positive net working capital balance."

 Operation of McREMI assets

   The Master Agreement provides that following the completion of the
transaction, Management LLC will own and operate the assets of McREMI
contributed in the transaction to WXI/McN Realty and its subsidiaries. The
Master Agreement provides that for a period ending no sooner than December 31
of the calendar year following the calendar year in which the closing occurs,
WXI/McN Realty will cause Management LLC to continue using certain of the
assets of McREMI contributed in the transaction to WXI/McN Realty and its
subsidiaries, subject to some rights to cease using McREMI assets if WXI/McN
Realty reasonably determines that the continued use of those assets is not
supported by sound business practices and to substitute more appropriate assets
if WXI/McN Realty determines that substitution would be sound business
practice. See "Special Factors--Plans for the McNeil Partnerships that
participate in the transaction."

   The Master Agreement also provides that Management LLC will make offers of
employment to some employees of McREMI.

   At the effective time of the mergers, McREMI will terminate the employment
of each employee that accepts an offer of employment from WXI/McN Realty or a
subsidiary of WXI/McN Realty as of the closing date and will cause the
termination of each other employee of the participating McNeil Partnerships and
their respective subsidiaries.

 [Additional disclosure for Fund XXV: Harbour Club I purchase option

   Fund XXV has granted to WXI/McN Realty the right to purchase the Harbour
Club I Apartments and Harbour Club Golf Course, at a price equal to $11,960,000
if (a) either Fund XXII or Fund XXIII or both are participating McNeil
Partnerships and (b) Fund XXV is an excluded McNeil Partnership. This right
will vest as of the effective time of the mergers. If WXI/McN Realty desires to
exercise its right to purchase the Harbour Club I Apartments and the Harbour
Club Golf Course, WXI/McN Realty must deliver a written notice to Fund XXV of
its election to do so promptly following the effective time of the mergers, but
in no event later than the fifteenth business day following the closing date.
In the event that WXI/McN Realty does not provide this notice to Fund XXV by
the fifteenth business day following the closing date, then WXI/McN Realty's
right will irrevocably lapse and Fund XXV's obligations in respect of that
right will be irrevocably discharged. The parties to the Master Agreement have
agreed that any closing of WXI/McN Realty's purchase of the Harbour Club I
Apartments and the Harbour Club Golf Course must be completed within 20
business days following the closing date.

   Notwithstanding anything to the contrary in the Master Agreement, if WXI/McN
Realty exercises its right to purchase the Harbour Club I Apartments and the
Harbour Club Golf Course, WXI/McN Realty will pay at

                                      129
<PAGE>

the closing of that transaction any outstanding mortgage debt secured by the
Harbour Club I Apartments or the Harbour Club Golf Course, including all
accrued but unpaid interest on that mortgage debt through the date of the
closing of WXI/McN Realty's purchase of the Harbour Club I Apartments and the
Harbour Club Golf Course, and all prepayment fees relating to that mortgage
debt. The purchase price of the Harbour Club I Apartments and the Harbour Club
Golf Course will be reduced by the amount of that mortgage debt, but not by the
amount of the related prepayment fees.

   WXI/McN Realty's obligation to close its purchase of the Harbour Club I
Apartments and the Harbour Club Golf Course is subject to the fulfillment or
waiver by WXI/McN Realty on the date of that closing of the following
conditions:

  . title to the Harbour Club I Apartments and the Harbour Club Golf Course
    being free and clear of all material property restrictions and
    encumbrances other than permitted restrictions and encumbrances and other
    than matters which would not preclude the continued use of the Harbour
    Club I Apartments and the Harbour Club Golf Course as they are being used
    as of the date of the Master Agreement or would not materially and
    adversely affect the value of the Harbour Club I Apartments and the
    Harbour Club Golf Course as they are being used as of the date of the
    Master Agreement; and

  . Lawyer's Title Insurance Corporation, or another nationally recognized
    title insurance company reasonably acceptable to Sellers and WXI/McN
    Realty, being unconditionally obligated and prepared, subject to the
    payment of the applicable title insurance premium and related charges at
    WXI/McN Realty's sole cost and expense, to issue to or for the benefit of
    WXI/McN Realty and one or more of its subsidiaries either (a) an extended
    coverage ATLA owner's policy of title insurance (or the equivalent in the
    applicable jurisdiction) effective as of the closing date of the
    transaction for the Harbour Club I Apartments and the Harbour Club Golf
    Course in an amount requested by WXI/McN Realty, which amount shall be
    commercially reasonable, or (b) at the option of WXI/McN Realty, a "date-
    down" to an existing policy of owner's title insurance, in each case in
    accordance with the title commitments given by Lawyer's Title Insurance
    Corporation to WXI/McN Realty, except for some permitted exclusions.

   If one or both of the conditions set forth in the preceding bullet points
are not satisfied at the time of the closing of WXI/McN Realty's purchase of
the Harbour Club I Apartments and the Harbour Club Golf Course and WXI/McN
Realty has not waived the unsatisfied condition prior to that time, McNeil
Partners and WXI/McN Realty have agreed to negotiate in good faith a fair
reduction in the purchase price of the Harbour Club I Apartments and the
Harbour Club Golf Course to take into account the matters with respect to which
the condition is not satisfied.

   At and after the effective time of the mergers, the owner of the Harbour
Club I Apartments and the Harbour Club Golf Course agrees, for so long as that
owner continues to own the Harbour Club I Apartments and the Harbour Club Golf
Course, to manage, or cause to be managed, either or both of the Harbour Club
II Apartments and the Harbour Club III Apartments, if so requested by their
respective owners, 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 that owner obtaining the consent or approval
of each person whose consent or approval is required to a change in the
management of that property.]

or any of their respective affiliates or subsidiaries of any debt or equity or

Conditions to closing

   The obligations of Sellers and WXI/McN Realty to effect the transaction are
subject to the fulfillment, or waiver by each party to the Master Agreement,
at or prior to the effective time of the mergers of the following conditions:

  . the approval of the merger proposal by the requisite number of limited
    partner units in each participating McNeil Partnership, other than McNeil
    Summerhill I, L.P., whose approval has already been obtained;

 Certain exclusions from conditions to closing

   The parties to the Master Agreement have agreed that because no excluded
McNeil Partnership is subject to the closing, none of the conditions to closing
described above in "--Conditions to closing" needs to be satisfied with respect
to any excluded McNeil Partnership or the subsidiaries, properties, etc. of any
excluded McNeil Partnership. See "--Termination of the Master Agreement--Right
to terminate the Master Agreement with respect to one or more McNeil
Partnerships."

   The Master Agreement also provides that the following shall not be
considered in determining whether or not any or all of the conditions to
closing described above in "--Conditions to closing--Conditions to each party's
obligations to close" and "--Conditions to closing--Conditions to WXI/McN
Realty's obligations to close" have been fulfilled:

  . any effect on any of the participating McNeil Partnerships' business,
    properties, financial condition or results of operations resulting,
    directly or indirectly, from WXI/McN Realty's failure to consent to a
    commercial lease or any amendment to any commercial lease as requested by
    Sellers in good faith; and

  . any effect on any of the participating McNeil Partnerships' business,
    properties, financial condition or results of operations resulting,
    directly or indirectly, from WXI/McN Realty's failure to consent to a
    proposal described in "--Material covenants--Reimbursable proposals"
    proposed by Sellers in good faith.

   The parties to the Master Agreement have agreed that none of the conditions
to closing described in paragraphs (1), (2), (3), (5), (6), (7), (8), (9) and
(10) under "--Conditions to closing--Conditions to WXI/McN Realty's obligations
to close," after giving effect to the paragraphs above, needs to be satisfied
with respect to any one or more McNeil Partnerships designated by WXI/McN
Realty as "Included Partnerships" (or the subsidiaries, properties, etc. of any
Included Partnership) or with respect to any one or more matters designated by
WXI/McN Realty as "Included Partnership Matters." See "--Conditions to
closing--Removal notices."

 Removal notices

   The Master Agreement provides that Sellers have the right to exclude one or
more McNeil Partnerships from the transaction in their discretion. For example,
Sellers may choose to exclude a particular McNeil Partnership because that
McNeil Partnership potentially may fail to satisfy the conditions to closing
described above in "--Conditions to closing--Conditions to WXI/McN Realty's
obligations to close" and therefore could result in the entire transaction
failing to close with respect to all of the participating McNeil Partnerships
unless that particular McNeil Partnership was excluded.

   At any time until and including the date of the limited partner meeting for
a participating McNeil Partnership, Sellers may provide a written "Matter
Removal Notice" to WXI/McN Realty identifying that McNeil Partnership as a
"Removable Partnership" and describing in reasonable detail matters relating to
that McNeil Partnership that Sellers believe in good faith may cause that
McNeil Partnership to become an

                                      136
<PAGE>

excluded McNeil Partnership as described in "--Termination of the Master
Agreement--Right to terminate the Master Agreement with respect to one or more
McNeil Partnerships." Upon WXI/McN Realty's receipt of any Matter Removal
Notice, WXI/McN Realty has a limited amount of time to provide written notice
to Sellers identifying which, if any, of the matters described in the Matter
Removal Notice WXI/McN Realty designates as an "Included Partnership Matter."
By designating a matter as an "Included Partnership Matter," WXI/McN Realty
agrees to close the transaction with the McNeil Partnership to which that
matter relates, provided that the McNeil Partnership is not otherwise excluded,
even if that McNeil Partnership does not satisfy the specified conditions to
closing described below.

  At any time following the date of the limited partner meeting of a
participating McNeil Partnership, Sellers may provide a written "Pre-Closing
Removal Notice" to WXI/McN Realty identifying that McNeil Partnership as a
"Pre-Closing Removable Partnership" which Sellers desire to exclude from the
transaction. Upon WXI/McN Realty's receipt of any Pre-Closing Removal Notice,
WXI/McN Realty has a limited amount of time to provide written notice to
Sellers identifying which, if any, of the Pre-Closing Removable Partnerships
WXI/McN Realty designates as an "Included Partnership." By designating a McNeil
Partnership as an "Included Partnership," WXI/McN Realty agrees to close the
transaction with that McNeil Partnership, provided that it is not otherwise
excluded, even if that McNeil Partnership does not satisfy the specified
conditions to closing described in the following paragraph.

  The parties to the Master Agreement have agreed that none of the conditions
to closing described in paragraphs (1), (2), (3), (5), (6), (7), (8), (9) and
(10) under "--Conditions to closing--Conditions to WXI/McN Realty's obligations
to close," after giving effect to the paragraphs in "--Conditions to closing--
Certain exclusions from conditions to closing," needs to be satisfied with
respect to any one or more Included Partnership Matters or any one or more
Included Partnerships (or any subsidiaries, properties, etc. of any Included
Partnership).

    respect to one or more McNeil Partnerships"), has become final and
    nonappealable; or

       (b) if the closing has not occurred on or before June 24, 2000;

 Right to terminate the Master Agreement with respect to one or more McNeil
 Partnerships

   In addition, under some circumstances, the Master Agreement may be
terminated with respect to a particular McNeil Partnership (an "excluded McNeil
Partnership") and that McNeil Partnership will be excluded from the
transaction, whether or not the requisite approvals of that McNeil Partnership
have been obtained, except as indicated to the contrary below. These
circumstances include, among others:

     (1) by the mutual written consent of each Seller and WXI/McN Realty;

     (2) by WXI/McN Realty, on the one hand, or any Seller, on the other
  hand,:

       (a) if, upon a vote at a duly held limited partner meeting or any
    adjournment of the limited partner meeting for that McNeil Partnership,
    the requisite approval of the limited partners of that McNeil
    Partnership of the merger proposal has not been obtained;

       (b) with respect to a McNeil Partnership if any judgment,
    injunction, order, decree or action by any governmental entity of
    competent authority preventing the consummation of the transaction with
    respect to that McNeil Partnership has become final and nonappealable;
    or

       (c) in respect of Fairfax only, following the date which is the
    tenth business day after the date of the mailing of this Proxy

    applicable WXI/McN Realty subsidiary as the general partner of Fairfax
    described under "--The contributions--Replacement of general partner"
    and the other transactions contemplated by the Master Agreement with
    respect to Fairfax has not been obtained.

    fiduciary duties to the limited partners of that McNeil Partnership
    and, as advised by counsel, determines that it is required to terminate
    the Master Agreement with respect to that McNeil Partnership because a
    superior acquisition proposal (as defined in "--Material covenants--No
    solicitation by Sellers") has been made with respect to that McNeil
    Partnership (see "--Material covenants--No solicitation by Sellers");

       (b) in respect of any one or more of the Pre-Closing Removable
    McNeil Partnerships which WXI/McN Realty has not designated in writing
    as an Included Partnership by a certain date; or

       (c) in respect of any one or more of the Removable McNeil
    Partnerships with respect to which WXI/McN Realty has not designated in
    writing as Included Partnership Matters all of the matters described in
    the Matter Removal Notice by a certain date; or

     (4) by WXI/McN Realty with respect to a McNeil Partnership, if the
  general partner of that McNeil Partnership:

       (a) has failed to recommend to the limited partners of that McNeil
    Partnership the approval of the merger proposal, in connection with an
    acquisition proposal by a third party in respect of that McNeil
    Partnership;

       (b) has withdrawn or modified in a manner adverse to WXI/McN Realty
    its approval or recommendation that the limited partners of that McNeil
    Partnership approve the merger proposal, in connection with an
    acquisition proposal for that McNeil Partnership; or

       (c) has approved or recommended an acquisition proposal for that
    McNeil Partnership.

 Effect of termination of the Master Agreement

   If the Master Agreement is validly terminated in its entirety by any Seller
or WXI/McN Realty as provided above under "--Right to terminate the Master
Agreement," or is validly terminated by any Seller or

                                      138
<PAGE>

WXI/McN Realty with respect to one or more McNeil Partnerships as provided
above under "--Right to terminate the Master Agreement with respect to one or
more McNeil Partnerships," the Master Agreement will become null and void and
of no further force or effect, in its entirety if it is terminated in its
entirety or with respect to one or more McNeil Partnerships if it is terminated
with respect to those McNeil Partnerships, as the case may be, and none of
Sellers or WXI/McN Realty, or any of their respective subsidiaries, or any of
their respective partners, stockholders, members, equity holders, directors,
officers, employees, affiliates, agents, representatives, successors or assigns
will have any liability or obligation under the Master Agreement except that:

  . in the case of termination of the Master Agreement in its entirety, any
    obligations of the parties to the Master Agreement relating to the
    following will survive termination of the Master Agreement:
    confidentiality; fees and expenses; effect of termination; nonsurvival of
    representations, warranties and covenants; no recourse of WXI/McN Realty
    and related parties to parties other than Sellers; payment of break-up
    fee; reimbursement of expenses; and the provisions set forth in Article
    XI of the Master Agreement;

  . one or more of Sellers or WXI/McN Realty may have liability to one or
    more of Sellers or WXI/McN Realty if the basis of the termination is a
    willful, material breach by one or more of Sellers or WXI/McN Realty of
    one or more of the provisions of the Master Agreement; and

  . in the case of termination of the Master Agreement in respect of a McNeil
    Partnership, the liabilities and obligations of the parties to the Master
    Agreement with respect to the other McNeil Partnerships would remain in
    effect, and any obligations of the parties to the Master Agreement
    relating to the following will survive termination of the Master
    Agreement in respect of that McNeil Partnership: confidentiality;
    correction and satisfaction of specified items relating to title;
    [additional disclosure for Fund XXV: the Harbour Club I purchase option;]
    public announcements; fees and expenses; binding effect of Stanger
    allocations; effect of termination; nonsurvival of representations,
    warranties and covenants; no recourse of WXI/McN Realty and related
    parties to parties other than Sellers; payment of break-up fee;
    reimbursement of expenses; and the provisions set forth in Article XI of
    the Master Agreement.

   The confidentiality agreement entered into as of March 25, 1999 among
Whitehall, McNeil Partners and McREMI will continue in effect notwithstanding
the termination of the Master Agreement in its entirety or the termination of
the Master Agreement with respect to one or more McNeil Partnerships. WXI/McN
Realty's obligation to hold any nonpublic information relating to Sellers or
the McNeil Partnerships' subsidiaries or any of their respective businesses or
properties in confidence to the extent required by, and in accordance with, the
provisions of the confidentiality agreement, and the obligation of WXI/McN
Realty to cause its subsidiaries and affiliates and each of its and their
officers, employees, accountants, counsel, financial advisors and other
representatives to do the same, shall survive the termination of the Master
Agreement in its entirety and the termination of the Master Agreement with
respect to one or more McNeil Partnerships. Notwithstanding the foregoing,
immediately following the closing of the transaction, the rights and
obligations under the confidentiality agreement of the parties to the
confidentiality agreement will terminate with respect to any participating
McNeil Partnership and the subsidiaries of that participating McNeil
Partnership.

   WXI/McN Realty has agreed in the Master Agreement that following termination
of the Master Agreement in its entirety or with respect to one or more McNeil
Partnerships, as the case may be, it will not, and will cause its affiliates
not to, oppose or seek to prevent or frustrate any transaction or agreement
that Sellers or any of their subsidiaries may propose or enter into relating to
any business combination between Sellers and any third party if the Master
Agreement is terminated in its entirety, or between Sellers and any third party
in respect of an excluded McNeil Partnership if the Master Agreement is
terminated in respect of one or more McNeil Partnerships. Notwithstanding the
foregoing, if Goldman, Sachs & Co. and its affiliates, including, without
limitation, Whitehall and WXI/McN Realty's managing member, (a) are not using
all or any portion of the material provided by the Sellers to Whitehall in
connection with Whitehall's evaluation of the transaction in violation of the
confidentiality agreement, and (b) are not using all or any portion of the
material

                                      139
<PAGE>

provided by the Sellers to Whitehall in connection with Whitehall's evaluation
of the transaction in any of the activities specified below and (c) are not in
violation of their obligation to hold any nonpublic information relating to
Sellers or the McNeil Partnerships' subsidiaries or any of their respective
businesses or properties in confidence to the extent required by, and in
accordance with, the provisions of the confidentiality agreement, and to cause
its subsidiaries and affiliates and each of its and their officers, employees,
accountants, counsel, financial advisors and other representatives to do the
same, then nothing in the Master Agreement will in any manner apply to or
restrict the activities of Goldman, Sachs & Co. and its affiliates from
engaging in asset management, brokerage, investment advisory, investment
banking, financial advisory, anti-raid advisory, financing, trading, market
making, arbitrage and other similar activities conducted in the ordinary course
of its and its affiliates' business.

Fees and expenses

 General

   Except as described in the following paragraph and in "--Aggregate
consideration--Prepayment and assumption of indebtedness," "--The mergers--
Exchange of certificates," "--Fees and expenses--Partnership break-up fee" and
"--Fees and expenses--Reimbursement of expenses," whether or not the
transaction is consummated, all costs and expenses incurred in connection with
the Master Agreement and the other transaction documents including, without
limitation, the fees, expenses and disbursements of counsel, financial advisors
and accountants, will be paid by the party incurring those costs and expenses.
See "Special Factors--Fees and expenses relating to the transaction."

   Without limiting the generality of the foregoing paragraph, whether or not
the transaction is consummated, McREMI has agreed that it will be liable for
the transaction expenses incurred by McREMI on behalf of itself and not on
behalf of the McNeil Partnerships or the McNeil Partnerships' subsidiaries.
Whether or not the transaction is consummated, each McNeil Partnership has
agreed that it will be liable for the amount of transaction expenses actually
incurred by it on behalf of itself and its subsidiaries and an amount equal to
that McNeil Partnership's ratable share of transaction expenses incurred by
Sellers that are not specifically identifiable to individual McNeil
Partnerships based on the relative percentage set forth in the column
"Partnership Percentage" in Table 2 opposite the name of that McNeil
Partnership. Notwithstanding the foregoing, a McNeil Partnership which becomes
an excluded McNeil Partnership as described in paragraph (2)(a) in "--
Termination of the Master Agreement--Right to terminate the Master Agreement
with respect to one or more McNeil Partnerships" will not be liable for
transaction expenses incurred by Sellers following the date on which that
McNeil Partnership became an excluded McNeil Partnership as described in such
paragraph (2)(a), and the participating McNeil Partnerships will share those
transaction expenses ratably, based on the relative percentages set forth in
the column "Partnership Percentage" in Table 2 opposite the name of the
participating McNeil Partnerships.

 Partnership break-up fee

   In addition, in some circumstances, WXI/McN Realty will receive a break-up
fee, calculated on a partnership by partnership basis, up to an aggregate
maximum of $18.0 million, if the Master Agreement is terminated with respect to
one or more McNeil Partnerships. In the case of termination of the Master
Agreement in these circumstances, each McNeil Partnership with respect to which
the Master Agreement has been terminated will be severally, but not jointly,
liable for payment to WXI/McN Realty of its respective partnership break-up
fee. These circumstances include, among others:

     (1) a Seller terminates the Master Agreement with respect to that McNeil
  Partnership because prior to the approval of the merger proposal by the
  limited partners of that McNeil Partnership, the general partner of that
  McNeil Partnership, in the exercise of its good faith judgment as to its
  fiduciary duties to the limited partners of that McNeil Partnership and, as
  advised by counsel, determines that it is required to terminate the Master
  Agreement with respect to that McNeil Partnership because a superior
  acquisition proposal has been made with respect to that McNeil Partnership
  (see paragraph 3(a) in "--Termination of the Master Agreement--Right to
  terminate the Master Agreement with respect to one or more McNeil
  Partnerships");

                                      140
<PAGE>

     (2)  WXI/McN Realty terminates the Master Agreement with respect to that
  McNeil Partnership because the general partner of that McNeil Partnership:

    . has failed to recommend to the limited partners of that McNeil
      Partnership the approval of the merger proposal, in connection with
      an acquisition proposal by a third party in respect of that McNeil
      Partnership;

    . has withdrawn or modified in a manner adverse to WXI/McN Realty its
      approval or recommendation that the limited partners of that McNeil
      Partnership approve the merger proposal, in connection with an
      acquisition proposal for that McNeil Partnership; or

    . has approved or recommended an acquisition proposal for that McNeil
      Partnership (see paragraphs 4(a), (b) and (c) in "--Termination of
      the Master Agreement--Right to terminate the Master Agreement with
      respect to one or more McNeil Partnerships");

     (3) if each of the following occurs:

    . either (A) a person who is not an affiliate of WXI/McN Realty,
      Whitehall or WXI/McN Realty's managing member consummates an
      acquisition of more than 10% of the outstanding limited partner units
      in that McNeil Partnership following the date of the Master Agreement
      or (B) a person who is not an affiliate of WXI/McN Realty, WXI/McN
      Realty's managing member or Whitehall makes an acquisition proposal
      for that McNeil Partnership;

    . WXI/McN Realty or any Seller terminates the Master Agreement with
      respect to that McNeil Partnership because, upon a vote at a duly
      held limited partner meeting or any adjournment of the limited
      partner meeting for that McNeil Partnership, the requisite approval
      of the limited partners of that McNeil Partnership of the merger
      proposal has not been obtained (see paragraph 2(a) in "--Termination
      of the Master Agreement--Right to terminate the Master Agreement with
      respect to one or more McNeil Partnerships"); and

    . that McNeil Partnership enters into a definitive agreement relating
      to a higher acquisition proposal (as defined below) within six months
      of that McNeil Partnership becoming an excluded McNeil Partnership;
      or

     (4) (A) the general partner of that McNeil Partnership as of the date of
  the Master Agreement is replaced and (B) WXI/McN Realty or any Seller
  terminates the Master Agreement with respect to that McNeil Partnership
  because, upon a vote at a duly held limited partner meeting or any
  adjournment of the limited partner meeting for that McNeil Partnership, the
  requisite approval of the limited partners of that McNeil Partnership of
  the merger proposal has not been obtained (see paragraph 2(a) in "--
  Termination of the Master Agreement--Right to terminate the Master
  Agreement with respect to one or more McNeil Partnerships").

   As used in this Proxy Statement "higher acquisition proposal" means an
acquisition proposal made by one or more persons which are not affiliates of
WXI/McN Realty, Whitehall or WXI/McN Realty's managing member with respect to a
McNeil Partnership, which WXI/McN Realty and the general partner of that McNeil
Partnership jointly determine to be more favorable to the limited partners of
that McNeil Partnership from a financial point of view than the merger
proposal. Notwithstanding the foregoing, the payment of the partnership break-
up fee by such person(s) will not be taken into consideration in determining
whether or not that acquisition proposal is more favorable to the limited
partners of that McNeil Partnership from a financial point of view than the
merger proposal. If WXI/McN Realty and the general partner of the applicable
McNeil Partnership are unable to reach agreement as to whether or not that
acquisition proposal is more favorable to the limited partners of that McNeil
Partnership from a financial point of view than the merger proposal within
three business days of that McNeil Partnership's execution of definitive
documents relating to that acquisition proposal, then WXI/McN Realty and that
McNeil Partnership agree to submit their dispute to the financial advisor,
selected as described in the following sentence, whose determination will be
final and binding upon all of the parties to the Master Agreement. In the case
of a higher acquisition proposal in which the consideration

                                      141
<PAGE>

offered to the limited partners is solely cash consideration, the financial
advisor will be Stanger & Co., and Stanger & Co. will make its determination
within ten business days. In the case of a higher acquisition proposal in which
the consideration offered to the limited partners involves non-cash
consideration, the financial advisor will be an investment bank which has been
selected by the mutual agreement of the parties, or failing that, an investment
bank which has been selected jointly by an investment bank selected by McNeil
Partners and an investment bank selected by WXI/McN Realty.

   In the case of termination of the Master Agreement as set forth in
paragraphs (1) through (4) above, each McNeil Partnership with respect to which
the Master Agreement has been terminated will be severally, but not jointly,
liable for payment to WXI/McN Realty of a fee equal to the partnership break-up
fee set forth opposite the name of that excluded McNeil Partnership in the
table below:

   The partnership break-up fees set forth in the foregoing table were
calculated based on the percentage set forth in the column "Partnership
Percentage" in Table 2 opposite the name of each McNeil Partnership. Each
excluded McNeil Partnership will be severally liable for payment of its
partnership break-up fee as set forth in the foregoing table and no other party
to the Master Agreement will have any liability to WXI/McN Realty or to an
excluded McNeil Partnership for the partnership break-up fee of that excluded
McNeil Partnership.

   Any payment of a partnership break-up fee required to be made as a result of
termination of the Master Agreement pursuant to paragraph (1) or (2) above will
be made not later than the earlier of (a) 90 days after the date of the
termination of the Master Agreement pursuant to paragraph (1) or (2) above and
(b) three business days after the date on which a definitive agreement relating
to an acquisition proposal is entered into. Any payment of a partnership break-
up fee required to be made pursuant to paragraph (1) or (2) above will accrue
interest at 10% per annum, compounded annually, from the date of the
termination of the Master Agreement pursuant to paragraph (1) or (2) above, and
no distribution or other payment will be made to the general partner or any
limited partner of that excluded McNeil Partnership until the partnership
break-up fee and the related accrued interest is paid in full.

   Any payment of a partnership break-up fee required to be made as a result of
termination of the Master Agreement pursuant to paragraph (3) above will be
made not later than the earlier of (a) 90 days after the date of the
termination of the Master Agreement pursuant to paragraph (3) above and (b)
three business days after the date on which a definitive agreement relating to
a higher acquisition proposal is entered into. Any payment required to be made
pursuant to paragraph (4) above will be made not later than three business days
after the date of the termination of the Master Agreement in respect of that
excluded McNeil Partnership pursuant to paragraph (4) above. Any payment of the
partnership break-up fee required to be made pursuant to paragraph (3) or (4)
above will accrue interest at 10% per annum, compounded annually, from the date
that payment is due, and no distribution or other payment will be made to the
general partner or any limited partner of that excluded McNeil Partnership
until the partnership break-up fee and the related accrued interest is paid in
full.

                                      142
<PAGE>

   The payment of the partnership break-up fee with respect to an excluded
McNeil Partnership is compensation and liquidated damages for any loss suffered
by WXI/McN Realty or any one or more of its affiliates or subsidiaries as a
result of the failure of the transaction with respect to that excluded McNeil
Partnership to be consummated and to avoid the difficulty of determining
damages under the circumstances, and will be the sole and exclusive remedy of
WXI/McN Realty, its affiliates and subsidiaries against Sellers and the McNeil
Partnerships' subsidiaries and their respective subsidiaries, partners,
stockholders, members, equity holders, directors, officers, employees,
affiliates, agents, representatives, successors and assigns with respect to the
occurrence giving rise to that payment.

   Any receipt by WXI/McN Realty of any one or more partnership break-up fees
will offset any obligation of Sellers to pay WXI/McN Realty's expenses as
described below in "--Fees and expenses--Reimbursement of expenses--WXI/McN
Realty's reimbursable expenses."

   Notwithstanding the foregoing paragraphs, WXI/McN Realty will not be
entitled to receive any partnership break-up fee if at the time any party to
the Master Agreement terminates the rights and obligations under the Master
Agreement in respect of one or more excluded McNeil Partnerships as described
in "--Termination of the Master Agreement--Right to terminate the Master
Agreement with respect to one or more McNeil Partnerships," WXI/McN Realty had
breached any of its representations, warranties, covenants, obligations or
agreements set forth in the Master Agreement and, as a result, the conditions
set forth in paragraph (1) or (2) under "--Conditions to closing--Conditions to
Sellers' obligations to close" cannot be satisfied by June 24, 2000.

 Reimbursement of expenses

  WXI/McN Realty's reimbursable expenses

   Sellers are required to pay WXI/McN Realty's and its affiliates' actual,
reasonable out-of-pocket expenses incurred in connection with the Master
Agreement and the transaction if:

     (1) (a) notwithstanding the satisfaction or waiver of all of the
  conditions set forth in "--Conditions to closing--Conditions to each
  party's obligations to close" and "--Conditions to closing--Conditions to
  Sellers' obligations to close," Sellers, exclusive of any excluded McNeil
  Partnership, fail to consummate the transaction prior to June 24, 2000; or

       (b) Sellers have failed to use their reasonable best efforts to
    satisfy the conditions set forth in "--Conditions to closing--
    Conditions to each party's obligations to close" and "--Conditions to
    closing--Conditions to Sellers' obligations to close;" and

     (2) WXI/McN Realty terminates the Master Agreement because:

        (a) the closing has not occurred on or before June 24, 2000 (see
    paragraph (2)(b) in "--Termination of the Master Agreement--Right to
    terminate the Master Agreement"); or

        (b) a Seller:

              .  materially breaches any of its representations, warranties,
                 covenants, obligations or agreements set forth in the Master
                 Agreement,

              .  that breach cannot be or is not remedied within 30 days, and

              .  the conditions set forth in paragraphs (1), (2) and (3) under
                 "--Conditions to closing--Conditions to WXI/McN Realty's
                 obligations to close" cannot be satisfied by June 24, 2000
                 (see paragraph (4) in "--Termination of the Master
                 Agreement--Right to terminate the Master Agreement").

   Sellers' obligation to pay WXI/McN Realty's expenses is limited to an amount
equal to the lesser of (a) $1,500,000 and (b) WXI/McN Realty's and its
affiliates' actual, reasonable out-of-pocket expenses incurred in connection
with the transaction, including, without limitation, all attorneys',
accountants' and investment bankers' fees and expenses. Sellers will be jointly
and severally liable for the payment of those expenses.

                                      143
<PAGE>

   Notwithstanding the forgoing, Sellers will not be obligated to pay WXI/McN
Realty's expenses if, at the time of termination of the Master Agreement by
WXI/McN Realty as described in paragraph (2) above, Sellers would have been
entitled to terminate the Master Agreement because WXI/McN materially breaches
any of its representations, warranties, covenants, obligations or agreements
set forth in the Master Agreement, that breach cannot be or is not remedied
within 30 days, and the conditions set forth in paragraphs (1) and (2) under
"--Conditions to closing--Conditions to Sellers' obligations to close" cannot
be satisfied by June 24, 2000 (see paragraph (3) in "--Termination of the
Master Agreement--Right to terminate the Master Agreement"). Any payment of
WXI/McN Realty's expenses required to be made by Sellers is required to be made
not later than 90 days after Sellers have received reasonably detailed
documents from WXI/McN Realty evidencing those costs and expenses.

   Notwithstanding the foregoing paragraphs, any receipt by WXI/McN Realty of
any one or more partnership break-up fees will offset any obligation of Sellers
to pay WXI/McN Realty's expenses.

   Notwithstanding the foregoing paragraphs, WXI/McN Realty will not be
entitled to receive any reimbursement of expenses by Sellers if at the time any
party to the Master Agreement terminates the rights and obligations under the
Master Agreement in respect of one or more excluded McNeil Partnerships as
described in "--Termination of the Master Agreement--Right to terminate the
Master Agreement with respect to one or more McNeil Partnerships," WXI/McN
Realty had breached any of its representations, warranties, covenants,
obligations or agreements set forth in the Master Agreement and, as a result,
the conditions set forth in paragraph (1) or (2) under "--Conditions to
closing--Conditions to Sellers' obligations to close" cannot be satisfied by
June 24, 2000.

  Sellers' reimbursable expenses

   WXI/McN Realty is required to pay Sellers' actual, reasonable out-of-pocket
expenses incurred in connection with the transaction if:

     (1) (a) notwithstanding the satisfaction or waiver of all of the
  conditions set forth in "--Conditions to closing--Conditions to each
  party's obligations to close" and "--Conditions to closing--Conditions to
  WXI/McN Realty's obligations to close" above, WXI/McN Realty fails to
  consummate the transaction prior to June 24, 2000; or

       (b) WXI/McN Realty has failed to use its reasonable best efforts to
    satisfy the conditions set forth in "--Conditions to closing--
    Conditions to each party's obligations to close" and "--Conditions to
    closing--Conditions to WXI/McN Realty's obligations to close" above;
    and

     (2) Sellers terminate the Master Agreement because:

       (a) the closing has not occurred on or before June 24, 2000 (see
    paragraph (2)(b) in "--Termination of the Master Agreement--Right to
    terminate the Master Agreement"); or

       (b) WXI/McN Realty:

              . materially breaches any of its representations, warranties,
               covenants, obligations or agreements set forth in the Master
               Agreement,

              . that breach cannot be or is not remedied within 30 days, and

              . the conditions set forth in paragraphs (1) and (2) under "--
               Conditions to closing--Conditions to Sellers' obligations to
               close" cannot be satisfied by June 24, 2000 (see paragraph (3)
               in "--Termination of the Master Agreement--Right to terminate
               the Master Agreement").

   WXI/McN Realty's obligation to pay Sellers' expenses is limited to an amount
equal to the lesser of (a) $1,500,000 and (b) Sellers' actual, reasonable out-
of-pocket expenses incurred in connection with the

                                      144
<PAGE>

transaction, including, without limitation, all attorneys', accountants' and
investment bankers' fees and expenses.

   Notwithstanding the forgoing, WXI/McN Realty will not be obligated to pay
Sellers' expenses if, at the time of termination of the Master Agreement by
Sellers as described in paragraph (2) above, WXI/McN Realty would have been
entitled to terminate the Master Agreement a Seller materially breaches any of

in the Master Agreement, that breach cannot be or is not remedied within 30
days, and the conditions set forth in paragraphs (1), (2) and (3) under "--
Conditions to closing--Conditions to WXI/McN Realty's obligations to close"

the Master Agreement--Right to terminate the Master Agreement"). Any payment of
Sellers' expenses required to be made by WXI/McN Realty is required to be made
not later than 90 days after WXI/McN Realty has received reasonably detailed
documents from Sellers evidencing those costs and expenses.

Amendments, modification, waiver; reservation of right to revise the
transaction

   The Master Agreement may be amended in writing by the parties to the Master
Agreement at any time (a) 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 (b) prior to the filing of any of the
merger certificates. However, after the requisite approvals of the limited
partners of any McNeil Partnership are obtained, no amendment, modification or
supplement shall be made which by law requires the further approval of those
limited partners without obtaining that further approval.

   At any time prior to the effective time of the mergers, the parties to the
Master Agreement may in writing (a) extend the time for the performance of any
of the obligations or other acts of any other party, (b) waive any inaccuracies
in the representations and warranties of any other party, or (c) waive
compliance with any of the agreements or conditions of any other party, in each
case, contained in the Master Agreement, the other transaction documents or in
any document delivered pursuant to the Master Agreement or the other
transaction documents. Any agreement on the part of a party to any extension or
waiver will be valid only if set forth in an instrument in writing signed on
behalf of that party. The failure of any party to the Master Agreement to
assert any of its rights under the Master Agreement or otherwise will not
constitute a waiver of those rights.

   Sellers and WXI/McN Realty may agree in writing to change the method of
effecting the business combination between any one or more Sellers and WXI/McN
Realty, including to provide for different forms of merger. Each party to the
Master Agreement is required to cooperate in those efforts. However, no change
may (a) alter or change the amount or kind of consideration to be received by
limited partners or general partners of the participating McNeil Partnerships,
(b) adversely affect the proposed tax treatment to limited partners or general
partners of the participating McNeil Partnerships or (c) materially delay the
consummation of any transaction.

                       WXI/McN REALTY OPERATING AGREEMENT

   This section of the Proxy Statement describes material provisions of the
WXI/McN Realty Operating Agreement. The description of the WXI/McN Realty
Operating Agreement contained in this Proxy Statement does not purport to be
complete and is qualified in its entirety by reference to the form of the
WXI/McN Realty Operating Agreement attached to this Proxy Statement as Appendix
B, and which is incorporated in this Proxy Statement by reference. Limited
partners of the Partnership are urged to read carefully the form of the WXI/McN
Realty Operating Agreement in its entirety.

   The Master Agreement provides that at the effective time of the mergers,
McNeil Partners and WXI/McN Realty's managing member will enter into the
WXI/McN Realty Operating Agreement which will govern the relationship between
McNeil Partners and WXI/McN Realty's managing member following the effective
time of the mergers.

Membership interests

   The WXI/McN Realty Operating Agreement provides for the issuance of five
classes of membership interests in WXI/McN Realty, depending on the amount of
financing obtained by WXI/McN Realty as of the closing and the amount of the
capital contributions made by McNeil Partners. Each class of membership
interests will entitle its holder to receive a specified percentage return on
its investment in WXI/McN Realty and to receive distributions of WXI/McN
Realty's net cash flow and net proceeds from capital transactions in the
priority set forth in the WXI/McN Realty Operating Agreement. Consequently,
McNeil Partners and the other McNeil Affiliates, through their ownership of
partnership interests in McNeil Partners, will have a significant interest in
WXI/McN Realty and will continue to have the opportunity to participate in any
future earnings growth and to benefit from any increases in the value of the
participating McNeil Partnerships and their properties, the McREMI assets and
any other assets acquired by WXI/McN Realty and its subsidiaries.

   However, the opportunity of the McNeil Affiliates to participate in any
future earnings growth of WXI/McN Realty is limited to the percentage return on
investment to which McNeil Partners is entitled. This percentage return is
limited to 14% or 15% per annum, depending on the amount of McNeil Partners'
initial capital contribution to WXI/McN Realty. WXI/McN Realty's managing
member is entitled to receive all returns in excess of the stated return which
the members are entitled to receive under the WXI/McN Realty Operating
Agreement. See "--Distributions to members of WXI/McN Realty."

   A summary of the five classes of membership interests in WXI/McN Realty,
including the percentage returns on investment to which the holders of those
interests are entitled, is set forth below. In calculating the returns on
investment, the amount of the investment will be reduced by the sum of all
distributions of net cash flow and net proceeds from capital transactions made
pursuant to the WXI/McN Realty Operating Agreement to the holders of the class
of interests corresponding to that investment.

 McNeil Class A Interests

   The McNeil Class A Interests will be issued in consideration for the McNeil
Class A Investment. The McNeil Class A Investment is the portion of McNeil
Partners' initial capital contribution equal to the greater of: (1) the
aggregate consideration allocated by Stanger & Co. to the general partner
interests in the participating McNeil Partnerships, the limited partner
interests in the Affiliated McNeil Partnerships, the assets of McNeil Partners
related to the participating McNeil Partnership and certain assets of McREMI
contributed to WXI/McN Realty and its subsidiaries and (2) the Minimum
Investment. "Minimum Investment" means the product determined by multiplying
$60 million by the sum of the percentages set forth in the column "Partnership
Percentage" in Table 2 opposite the name of each participating McNeil
Partnership. See "Special Factors--Interests of certain persons in the
transaction; conflicts of interest--Equity interest of McNeil Partners in
WXI/McN Realty."


                                      146
<PAGE>

   The rate of return on the McNeil Class A Investment is equal to 14% per
annum, compounded annually, if McNeil Partners' initial capital contribution is
less than the $70 Million Threshold (as defined below). If McNeil Partners'
initial capital contribution is equal to or greater than the $70 Million
Threshold, the rate of return on the McNeil Class A Investment is 15% per
annum, compounded annually. The "$70 Million Threshold" means the product
determined by multiplying $70 million by the sum of the percentages set forth
in the column "Partnership Percentage" in Table 2 opposite the name of each
participating McNeil Partnership.

 McNeil Class B Interests

   The McNeil Class B Interests will be issued in consideration for the McNeil
Class B Investment. The McNeil Class B Investment is the sum of (1) the portion
of McNeil Partners' initial capital contribution, if any, that was not included
in the McNeil Class A Investment or the McNeil Class C Investment and (2)
additional capital contributions made by McNeil Partners. McNeil Partners does
not have the right to make additional capital contributions to WXI/McN Realty
except in some limited circumstances.

   The rate of return on the McNeil Class B Investment is the same as the rate
of return on the McNeil Class A Investment.

 McNeil Class C Interests

   The McNeil Class C Interests will be issued in consideration for the McNeil
Class C Investment. The McNeil Class C Investment is the portion of McNeil
Partners' initial capital contribution that is in excess of the $70 Million
Threshold. Notwithstanding the foregoing, McNeil Partners will receive no
McNeil Class C Interests unless McNeil Partners' initial capital contribution
equals or exceeds the product determined by multiplying $75 million by the sum
of the percentages set forth in the column "Partnership Percentage" in Table 2
opposite the name of each participating McNeil Partnership.

   The rate of return on the McNeil Class C Investment is 13% per annum,
compounded annually.

 Whitehall Class A Interests

   The Whitehall Class A Interests will be issued in consideration for the
Whitehall Class A Investment. The Whitehall Class A Investment is the sum of
the portion of Whitehall's initial capital contribution and the portion of any
additional capital contributions that were not included in the Whitehall Class
B Investment.

   The rate of return on the Whitehall Class A Investment is the same as the
rate of return on the McNeil Class A Investment and the McNeil Class B
Investment.

 Whitehall Class B Interests

   The Whitehall Class B Interests will be issued in consideration for the
Whitehall Class B Investment. The Whitehall Class B Investment is the portion
of Whitehall's capital contribution equal to the sum of (1) the portion of
Whitehall's initial capital contribution that, if treated as "preferred equity
financing" (as defined below), would cause the total debt to total value ratio
of WXI/McN Realty to equal 80% and (2) the portion of any additional capital
contribution to fund working capital expenses that if treated as preferred
equity financing would cause the total debt to total value ratio of WXI/McN
Realty with respect to amounts used or incurred to funding working capital
expenses to equal 80%. The Whitehall Class B Investment is capped at
approximately $95 million, assuming all of the McNeil Partnerships participate
in the transaction. If one or more of the McNeil Partnerships does not
participate in the transaction, this cap will be reduced by the expected
preferred equity financing amounts that have been determined by WXI/McN Realty
with respect to each of the non-participating McNeil Partnerships.

   The rate of return on the Whitehall Class B Investment is 14% per annum,
compounded annually.

  "Preferred equity financing" as used in this Proxy Statement means (1) debt
incurred by WXI/McN Realty or its subsidiaries secured by equity interests in
one or more of WXI/McN Realty's subsidiaries or (2) preferred equity issued by
any of WXI/McN Realty's subsidiaries, which by its terms has a final redemption
or maturity date.

      advisor or property manager;

    --entering into or amending any non-market transaction outside the
      ordinary course with affiliates of WXI/McN Realty; and

                 OTHER AGREEMENTS BETWEEN THE McNEIL AFFILIATES
                        AND AFFILIATES OF WXI/McN REALTY

Indemnification and pledge agreement

   The Master Agreement provides that on the closing date of the transaction,
McNeil Partners and WXI/McN Realty's managing member will enter into an
Indemnification and Pledge Agreement. Under the Indemnification and Pledge
Agreement, McNeil Partners, and, under some circumstances, Robert A. McNeil,
has agreed to indemnify WXI/McN Realty's managing member and some of its
affiliates for all actual and out-of-pocket costs, expenses, judgments, fines,
losses, claims, damages and liabilities arising from certain matters. See
"Special Factors--Effects of the transaction--Benefits and detriments to the
McNeil Affiliates."

   These matters include the following:

  .  claims made in derivative or class action lawsuits or both, other than
     lawsuits relating to hazardous materials or any violation of any
     environmental law, filed prior to the closing date of the transaction
     against one or more of McREMI, the participating McNeil Partnerships and
     their affiliates;

  .  any litigation challenging the fairness of the transaction or
     challenging the fairness of the bidding process leading up to the
     transaction;

  .  lawsuits, other than lawsuits relating to hazardous materials or any
     violation of any environmental law, brought by persons who were limited
     partners of a participating McNeil Partnership prior to the closing of
     the transaction against that participating McNeil Partnership's general
     partner, the subsidiary of WXI/McN Realty which replaced that general
     partner or their affiliates for breach of fiduciary duty, usurping of
     partnership opportunity or similar breach of care or loyalty claims,
     which allege a disproportionate economic or personal benefit has accrued
     to the McNeil Affiliates or their affiliates to the detriment of those
     limited partners and which was not otherwise protected by the business
     judgment rule (in other words, acts of self-dealing or acts contrary to
     the best interests of the McNeil Partnership);

  .  any exercise of any statutory dissenters' rights or statutory rights of
     appraisal by limited partners of the participating McNeil Partnerships
     in connection with the mergers, to the extent that the aggregate amount
     of actual and out-of-pocket costs, expenses, judgments, fines, losses,
     claims, damages and liabilities exceeds the portion of the merger
     consideration which the dissenting limited partner had the right to
     receive and which was not paid to the dissenting limited partner;

  .  any obligations of McNeil Partners under any landlord estoppels
     delivered by McNeil Partners to WXI/McN Realty to satisfy the condition
     to closing requiring the delivery of commercial tenant estoppels (see
     "The Master Agreement--Conditions to closing--Conditions to WXI/McN
     Realty's obligations to close");

  .  any breach by McNeil Partners of its obligations to indemnify WXI/McN
     Realty from obligations incurred by McNeil Partners or McNeil Investors
     prior to the closing date of the transaction as an indemnitor under some
     existing indemnification obligations and agreements relating to mortgage
     debt on McNeil Partnership properties (see "The Master Agreement--
     Material covenants--Replacement indemnification agreements"); and

  .  any payment required to be made by an affiliate of WXI/McN Realty's
     managing member, as the indemnifying party, to other affiliates of
     WXI/McN Realty, as the indemnified parties, which the affiliate of
     WXI/McN Realty's managing member has agreed to indemnify for the same
     matters for which McNeil Partners, and, under some circumstances, Robert
     A. McNeil, has agreed to indemnify WXI/McN Realty's managing member.

   To secure the payment of McNeil Partners' indemnification obligations
described above, McNeil Partners has agreed to pledge and grant a security
interest in its McNeil Class A Interests to WXI/McN Realty's managing member
for the benefit of the affiliates of WXI/McN Realty that are being indemnified
under the

                                      151
<PAGE>

Indemnification and Pledge Agreement and under the indemnification agreement
between the affiliate of WXI/McN Realty's managing member and the other
affiliates of WXI/McN Realty described in the final bullet point above. See
"WXI/McN Realty Operating Agreement--Membership interests." The sole recourse
of WXI/McN Realty and each of the other indemnified parties against McNeil
Partners with respect to the indemnifiable matters is against the pledged
interests. If McNeil Partners' investment in WXI/McN Realty with respect to the
pledged interests decreases below a minimum threshold amount because of the
receipt of a distribution of capital from WXI/McN Realty with respect to the
pledged interests or because all of the pledged interests are "cashed out" or
exchanged for non-cash consideration, cash consideration or both pursuant to
the terms of the WXI/McN Realty Operating Agreement, McNeil Partners has agreed
to cause Robert A. McNeil to execute and deliver to WXI/McN Realty's managing
member a personal indemnity for the amount necessary to make up the difference
between that minimum threshold amount and the amount of the investment, taking
into account any such personal indemnities previously delivered by Robert A.
McNeil.

   The indemnification obligations of McNeil Partners and Robert A. McNeil
described above will terminate on the earlier of:

  .  the later of the fifth anniversary of the closing date of the
     transaction and the date of the final determination, after expiration of
     all appeals, of all indemnified proceedings commenced prior to the fifth
     anniversary of the closing date of the transaction and payment of all
     indemnifying amounts with respect to those proceedings, and

  .  subject to the delivery by Robert A. McNeil of the personal indemnity
     described above, the date on which all of the pledged interests are
     "cashed out" or exchanged for non-cash consideration, cash consideration
     or both pursuant to the terms of the WXI/McN Realty Operating Agreement.

Whitehall standstill agreement

   On March 25, 1999, Whitehall, its affiliates and subsidiaries and McNeil
Partners, McREMI, Robert A. McNeil and their affiliates entered into a
confidentiality agreement. In the confidentiality agreement, Whitehall agreed

prior written consent of McNeil Partners, McREMI, Robert A. McNeil and their
affiliates, take certain actions with respect to McNeil Partners, McNeil
Investors, McREMI, McNeil Summerhill, Inc., the McNeil Partnerships or their
subsidiaries. To induce Sellers and Robert A. McNeil to enter into the Master
Agreement, on June 24, 1999, Whitehall agreed to an extension to December 31,
2000 of the standstill provision contained in the confidentiality agreement.
The agreement extending Whitehall's standstill provision contained in the
confidentiality agreement provides that for the period commencing on June 24,
1999 and ending on and including December 31, 2000, Whitehall will not, without
the prior written consent of McNeil Partners, take any of those actions
prohibited by the standstill provision in the confidentiality agreement,
subject to limited exceptions.

     expressly contemplated by the Master Agreement as a result of the
     consummation of the transaction;

     to the voting of any securities of any of Sellers or the McNeil
     Partnerships' subsidiaries, except as contemplated by this Proxy
     Statement;

  .  forming, joining or otherwise participating in a "group," within the

1994, reflects the liabilities that were deferred under the Chapter 11
proceeding as "Liabilities subject to compromise."

                CERTAIN FINANCIAL PROJECTIONS OF THE PARTNERSHIP

   The Partnership does not as a matter of course publicly disclose internal
budgets, plans, estimates, forecasts or projections as to future revenues,
earnings or other financial information. The projected financial data set forth
below reflect information which was contained in projections prepared by McNeil
Partners and delivered to bidders in the auction. See "Special Factors--
Background of the transaction--Background of the auction process." These
projections were based upon a variety of estimates and assumptions, the
material ones of which are set forth below. The estimates and assumptions
underlying the projections involved judgments with respect to, among other
things, future economic, competitive, and financial market conditions and
future business decisions which may not be realized and are inherently subject
to significant business, economic and competitive uncertainties, all of which
are difficult to predict and many of which are beyond the control of the
Partnership. While McNeil Partners believes these estimates and assumptions are
reasonable, there can be no assurance that the projections will be accurate,
and actual results may vary materially from those shown. In light of the
uncertainties inherent in forward looking information of any kind, the
inclusion of these projections herein should not be regarded as a
representation by the Partnership, McNeil Partners or any other person that the
anticipated results will be achieved and limited partners are cautioned not to
place undue reliance on such information.

   The Partnership does not intend to update or otherwise revise the
information set forth below to reflect circumstances existing after the date of
the most recent financial statements incorporated by reference in this Proxy
Statement or to reflect the occurrence of unanticipated events. The information
set forth below should be read together with the information contained in the
Partnership's Annual Report on Form 10-K for the year ended December 31, 1998
and the information included or incorporated by reference in this Proxy
Statement.

   In the normal course of operations, McNeil Partners drafted a five-year
business plan in 1998. Subject to the qualifications and limitations stated
above, the information set forth below reflects the material assumptions used
in the Partnership's 1999 Business Plan.

   [For each of the McNeil Partnerships, the information set forth below with
respect to that McNeil Partnership will be included in the Proxy Statement for
that McNeil Partnership:]

                           FORWARD-LOOKING STATEMENTS

   This Proxy Statement and the documents incorporated by reference contain
certain forward-looking statements regarding the operations and business of the
Partnership. Statements in this document that are not historical facts are
"forward-looking statements." Such forward-looking statements include those
relating to:

  . the Partnership's future business prospects,

  . possible acquisitions, and

  . projected revenues, working capital, liquidity, capital needs, interest
    costs and income.

   The words "estimate," "project," "intend," "expect" and similar expressions
are intended to identify forward-looking statements. These forward-looking
statements are found at various places throughout this Proxy Statement.
Wherever they occur in this Proxy Statement or in other statements attributable
to the Partnership, McNeil Partners or the McNeil Affiliates, forward-looking
statements are necessarily estimates reflecting best judgments. However, these
statements still involve a number of risks and uncertainties that could cause
actual results to differ materially from those suggested by the forward-looking
statements. Discussions in this Proxy Statement under the captions "Summary,"
"Special Factors," "WXI/McN Realty Operating Agreement" and "Certain Financial
Projections of the Partnership" are particularly susceptible to risks and
uncertainties. Such forward-looking statements should, therefore, be considered
in light of various important factors, including those set forth in this Proxy
Statement and other factors set forth from time to time in the Partnership's
reports and registration statements filed with the SEC. You are cautioned not
to place undue reliance on these forward-looking statements, which speak only
as of the date hereof. The Partnership disclaims any intent or obligation to
update forward-looking statements. Moreover, the Partnership, through senior
management of McNeil Investors, the general partner of McNeil Partners, may
from time to time make forward-looking statements about the matters described
herein or other matters concerning the Partnership.

                              INDEPENDENT AUDITORS

   The consolidated financial statements and schedule of the Partnership as of
December 31, 1998 and 1997, and for the three years in the period ended
December 31, 1998, incorporated by reference into this Proxy Statement, have
been audited by Arthur Andersen LLP, independent public accountants, as
indicated in their reports with respect thereto, and are included herein in
reliance upon the authority of said firm as experts in accounting and auditing
in giving said reports. It is expected that representatives of Arthur Andersen
LLP will be present at the meeting, both to respond to appropriate questions of
limited partners and to make a statement if they so desire.

                           LIMITED PARTNER PROPOSALS

   If the merger of the Partnership is consummated, there will be no limited
partners of the Partnership other than WXI/McN Realty or its indirectly wholly
owned subsidiary. If the transaction is not consummated with respect to the
Partnership, limited partners of the Partnership would continue to be entitled
to participate in future meetings in accordance with the terms of the limited
partnership agreement. Other than the meeting scheduled to consider and vote on
the merger proposal, there are no meetings scheduled, and McNeil Partners
cannot predict when, if ever, future meetings may be called. Meetings may be
called upon notice by McNeil Partners to the limited partners or by notice to
McNeil Partners by limited partners holding at least 10% of the outstanding
units of limited partner interest. Any proposals by limited partners intended
to be presented at a meeting must be received by McNeil Partners not less than
60 nor more than 90 days prior to such meeting, provided that, in the event
that the Partnership gives less than 10 days' notice or prior public disclosure
of the date of the meeting, notice must be received by McNeil Partners no later
than the close of business on the tenth day following such notice or prior
public disclosure. For a limited partner to bring other business before a
meeting, timely notice must be received by McNeil Partners within the time
limits described above. Such notice must include a description of the proposed
business, the reasons therefore, and other specific matters. In

                                      192
<PAGE>

each case, the notice must be given to McNeil Partners at the Partnership's
principal address. Any limited partner desiring a copy of the Partnership's
limited partnership agreement will be furnished a copy without charge upon
written request of McNeil Partners.

                      WHERE YOU CAN FIND MORE INFORMATION

   As required by law, the Partnership files reports, proxy statements and
other information with the SEC. Because the transaction is a "going private"
transaction, the Partnership has filed a Rule 13e-3 Transaction Statement on
Schedule 13E-3 with respect to the transaction. You can read and copy these
materials at the public reference facilities maintained by the SEC at:

   Room 1024
   450 Fifth Street, N.W.
   Washington, D.C. 20549

   and at the following regional offices of the SEC:

   13th Floor
   New York, New York 10048

   and

   Suite 1400
   500 West Madison Street
   Chicago, Illinois 60661.

   For further information concerning the SEC's public reference rooms, you may
call the SEC at 1(800) SEC-0330. Some of this information may also be accessed
on the World Wide Web through the SEC's Internet address at
"http://www.sec.gov."

   You should rely only on the information contained in (or incorporated by
reference into) this Proxy Statement in connection with your consideration of
the merger proposal and the amendment proposal. Neither McNeil Partners nor the
Partnership has authorized anyone to give any information different from the
information contained in (or incorporated by reference into) this Proxy
Statement. This Proxy Statement is dated     , 1999. You should not assume that
the information contained in this Proxy Statement is accurate as of any later
date, and the mailing of this Proxy Statement to limited partners shall not
create any implication to the contrary.

                       ANNUAL REPORT AND QUARTERLY REPORT

   The Partnership's Annual Report on Form 10-K for the year ended December 31,
1998, and the Partnership's Quarterly Report on Form 10-Q for the quarter ended
   , 1999 (in each case, not including exhibits to those reports), are being
mailed with this Proxy Statement to all limited partners of the Partnership.

                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

   The SEC allows us to "incorporate by reference" the information we file with
them, which means that we can disclose important information to you by
referring you to those documents. The information incorporated by reference is
an important part of this proxy statement, and information that we file later
with the SEC will

                                      193

   Section 1.2 Closing. The closing of the Mergers and the other transactions
contemplated by this Agreement to take place at the Effective Time (the
"Closing") shall take place at a time and on a date (the "Closing Date") to be
specified by the parties hereto, which shall be no later than the fifth
business day after the later of (i) the date upon which the last unsatisfied or
unwaived condition to Closing set forth in Sections 8.1, 8.2 and 8.3 hereof is
satisfied or waived and (ii) the Pre-Closing Removal Notice Date, at the
offices of Sullivan & Cromwell, 125 Broad Street, New York, New York 10004,
unless another time, date or place is agreed to in writing by Sellers and the
Company.

   Section 1.3 Allocation of the Aggregate Consideration.

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

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

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

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

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

   Section 1.4 Additional Consideration. Immediately prior to the Effective
Time, in accordance with Sections 2.3 and 7.9(b) hereof and Section 6.1 of the
LLC Agreement, the Company shall issue to MPLP (or another designee of the
Contributing Partners) Company Interests, and MPLP (or another designee of the

                                      A-4
<PAGE>

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

   Section 1.5 Indebtedness.

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

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

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

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

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

                                      A-5

be received by holders of LP Interests and holders of GP Interests in the

   Section 2.4 Pre-Closing Distribution.

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

   (b)(i) Within four (4) business days (the "Objection Period") after the
delivery by MPLP to the Company of the Preliminary Pre-Closing Balance Sheet
and Preliminary Excess Cash Balance Schedule for a McNeil Partnership and all
relevant books and records and any work papers (including those of Arthur
Andersen LLP, Sellers' accountants) relating to the preparation of such
Preliminary Pre-Closing Balance Sheet and such Preliminary Excess Cash Balance
Schedule (including unaudited statements of operations and cash flows (prepared
in accordance with GAAP applied consistently with past practice), bills,
receipts and other written correspondence evidencing any amounts of Transaction
Expenses), the Company and its accountants shall complete their review of such
Preliminary Pre-Closing Balance Sheet and such Preliminary Excess Cash Balance
Schedule. Sellers shall make readily available to the Company, on a timely
basis during the Objection Period, all relevant books and records and any work
papers (including those of Arthur Andersen LLP, Sellers' accountants) relating
to the preparation of the Preliminary Pre-Closing Balance Sheets and the
Preliminary Excess Cash Balance Schedules (including unaudited statements of
operations and cash flows, bills, receipts and other written correspondence
evidencing any amounts of Transaction Expenses) and all other items reasonably
requested by the Company. In addition, Sellers and the Company shall make their
relevant personnel reasonably available to each other to respond to inquiries
relating to any of the materials described in the preceding sentence or any
matters raised by the Company. On or before the last day of the Objection
Period, the Company shall deliver to MPLP a reasonably detailed written
statement of any objections or disagreements, including the reasons therefor,
with respect to any Preliminary Pre-Closing Balance Sheet and Preliminary
Excess Cash Balance Schedule (the "Objection Statement") (it being understood
that neither the inclusion on any Preliminary Excess Cash Balance Schedule of
any line item not listed on Annex D hereto nor the exclusion

                                      A-8
<PAGE>

from any Preliminary Excess Cash Balance Schedule of any line item listed on
Annex D hereto shall be the subject of any such objection or disagreement). If
the Company does not provide MPLP with the Objection Statement with respect to
the Preliminary Pre-Closing Balance Sheet or the Preliminary Excess Cash
Balance Schedule with respect to a McNeil Partnership within the Objection
Period, the parties hereto shall be deemed to have unconditionally accepted and
agreed to, and shall be unconditionally bound by, the Preliminary Pre-Closing
Balance Sheet, the Preliminary Excess Cash Balance Schedule and the Preliminary
Excess Cash Balance set forth on such Preliminary Excess Cash Balance Schedule,
in each case, with respect to such McNeil Partnership, other than with respect
to the Specified Transaction Expenses which shall be updated to a subsequent
date in accordance with Note 17 to the Excess Cash Balance Schedule.

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

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

   (c) For each Participating McNeil Partnership for which the Excess Cash
Balance is greater than zero (a "Positive Excess Cash Balance"), MPLP shall
cause such Participating McNeil Partnership, on the Closing Date and
immediately prior to the consummation of any of the transactions contemplated
by Section 2.3(a) hereof, to irrevocably declare a cash distribution, in an
amount equal to the Positive Excess Cash Balance for such Participating McNeil
Partnership, to the persons who were limited partners (prior to the
consummation of

                                      A-9
<PAGE>

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 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 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.

LP Interest or any holder of any GP Interest:

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 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

                                      A-11
<PAGE>

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

Transitory Partnership shall no longer be outstanding and shall automatically
be cancelled and retired and shall cease to exist, and each holder of such GP
Interests shall cease to have any rights in respect thereto.

   Section 3.5 Payment of Merger Consideration.

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

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 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 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").

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

environmental reports, studies, assessments, sampling data and other
environmental information, in each case, that is in their possession and that

   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

                                      A-25
<PAGE>

no pending or, to the Knowledge of Sellers, threatened audits, examinations,
investigations or other proceedings in respect of Taxes or Tax matters. The
most recent audited McNeil Partnership Statements contained in the Seller SEC
Documents or made available to the Company, as the case may be, reflect an
adequate reserve for all material Taxes payable by the McNeil Partnerships and
their respective Seller Subsidiaries for all taxable periods and portions
thereof through the date of such financial statements, which Taxes are material
to the McNeil Partnerships and their respective Seller 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

   (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

                                      A-26
<PAGE>

of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of
them, or the single-employer plan of a McREMI ERISA Affiliate, that has not
been satisfied in 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

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 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.

any of their respective Seller Subsidiaries has any employees.

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

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 violation or default,
individually or in

                                      A-27
<PAGE>

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

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,

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.

Seller Subsidiary relating to the development or construction of, or additions
or expansions to, any McNeil Partnership Property which are currently in effect
as of the date specified in such Schedule 4.15(g) (collectively, the

dollars ($20,000). Complete and correct copies of Construction Contracts in
effect as of the date specified in Schedule 4.15(g) of the Seller Disclosure

LLCs and the Transitory Partnerships.

   (a) The Company is a limited liability company duly formed and validly
existing under the laws of the State of Delaware and has the requisite power
and authority to carry on its business as now being conducted and on or prior
to the Effective Time will be duly qualified or licensed to do business and
will be in good standing (with respect to jurisdictions which recognize such
concept) in each jurisdiction in which the nature of its business or the
ownership, leasing or use of its properties makes such qualification or
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 other Transaction Documents
to which the Company is a party. The Company has delivered to Sellers complete
and correct copies of the Original LLC Agreement, as amended or supplemented to
the date of this Agreement. The Company was formed solely for the purpose of
engaging in the transactions contemplated by this Agreement and has not engaged
in any business activities or conducted any operations other than as expressly
provided for in this Agreement. Other than the Transitory Partnerships and the
Company LLCs upon their formation, the Company has never owned any capital
stock or other equity interests in any other person.

   (b) Prior to the contributions described in Section 2.3(a) hereof and in
Section 6.1 of the LLC Agreement, the Company will have no assets or
liabilities or obligations whatsoever (other than the rights and obligations
set forth in this Agreement, the LLC Agreement, the Commitment Letter and any
debt commitment letter the Company may obtain) (the parties hereto acknowledge
and agree that nothing in this Section 5.1(b) shall affect or be deemed to
amend or modify any provision of this Agreement, including Sections 8.1, 8.2
and 8.3 hereof).

   (c) From the time of their formation through to the Effective Time, each
Company LLC and each Transitory Partnership will be an entity duly formed and
validly existing under the laws of the state of its formation and shall have
the requisite power and authority to carry on its business and will be duly
qualified or licensed to do business and will be in good standing (with respect
to jurisdictions which recognize such concept) in each jurisdiction in which
the nature of its business or the ownership, leasing or use of its properties
makes such qualification or licensing necessary, other than in such
jurisdictions where the failure to be so qualified or licensed or to be in good
standing, individually or in the aggregate, would not prevent the consummation
of the transactions contemplated by this Agreement. The Company will deliver to
Sellers complete and correct copies of the formation documents of each Company
LLC and each Transitory Partnership. Each Company LLC and each Transitory
Partnership will be formed solely for the purpose of engaging in the
transactions contemplated by this Agreement and will not engage in any business

or exercisable for interests having the right to vote) with members of the
Company on any matter. Except as set forth above, there are no outstanding
securities, interests, options, warrants, calls, rights, commitments,
agreements, arrangements or undertakings of any kind obligating the Managing
Member, the Company or any affiliate or subsidiary of the Company to issue,

in the Company or securities or interests convertible, exchangeable or
exercisable into interests in the Company. There are no agreements,
arrangements or understandings of any kind with respect to the voting of
interests in the Company or which restrict the transfer of any such interests,
except as provided in the Original LLC Agreement.

all of the outstanding interests in the other Company LLCs. As of their
formation and through to the Effective Time, the Company or the Sub LLC will
own all of the outstanding LP Interests in, and the applicable New GP LLC will
own all of the outstanding GP Interests in, each Transitory Partnership. Except
as expressly provided for in this Agreement, from their formation through to
the Effective Time, no interests in the Company LLCs or the Transitory
Partnerships will be issued, reserved for issuance or outstanding, and there
will be no outstanding securities, interests, options, warrants, calls, rights,
commitments, agreements, arrangements or undertakings of any kind obligating
any such entity to issue, deliver or sell, or cause to be issued, delivered or
sold, additional interests in such entity or securities or interests
convertible, exchangeable or exercisable into interests in such entity.

Company of the transactions contemplated by this Agreement and the other

necessary action on the part of the Company. This Agreement has been duly
executed and delivered by the Company, and each of the other Transaction

consummation by the Company of the transactions contemplated by this Agreement
and the other Transaction Documents to which it is a party and compliance by
the Company with the provisions of this Agreement and the other Transaction
Documents to which it is a party shall not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to loss of a benefit under, or any other change in rights or
obligations of any party under (including the right to amend or modify or
refuse to perform or comply with), or result in the creation of any Lien upon
any of the properties or assets of the Managing Member, the Company or any of
its subsidiaries under (i) the certificate of formation, operating agreement or
other organizational documents of the Company or the Managing Member, the
charter, bylaws or other organizational documents of any such subsidiary which

violations, defaults, rights, losses or Liens that, individually or in the
aggregate, would not 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.

   (d) No consent, approval, order or authorization of, or filing with any
Governmental Entity or third party is required by or with respect to the

<PAGE>

Documents or the consummation by the Company of the transactions contemplated
by this Agreement and the other Transaction Documents, except for (i) the
acceptance for record of the Merger Certificate and any other documents
required by the Governing Law applicable to each Participating McNeil
Partnership and its respective Transitory Partnership, by the Secretary of
State of the state of formation of such Participating McNeil Partnership and
such Transitory Partnership or (ii) such other consents, approvals, orders or
authorizations of, or filings with, any Governmental Entity or third party
which, if not obtained or made, would not 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.

   (e) For purposes of determining compliance with the HSR Act only, the
Company confirms that the conduct of its business and the business of its
subsidiaries consists solely of investing in, owning, developing, managing and
operating real estate, directly or through one or more subsidiaries, for the
benefit of its stockholders or members, as the case may be.

   Section 5.4 Compliance with Laws. None of the Managing Member, the Company
nor any of the Company's subsidiaries is violating or failing to comply with,
or has violated or failed to comply with, any Law of any Governmental Entity
applicable to its business, properties or operations, except to the extent that
such violation or failure to comply, individually or in the aggregate, would
not 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. No investigation or review by any
Governmental Entity with respect to the Managing Member, the Company or any
subsidiary of the Company is pending or, to the Knowledge of the Company,
threatened, nor has any Governmental Entity indicated an intention to conduct
the same, except for those the outcome 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. To the Knowledge of the
Company, no material change is required in the processes, properties or
procedures of the Managing Member, the Company or any subsidiary of the Company
in connection with any such Laws, and neither the Managing Member, the Company
nor any subsidiary of the Company has received any written notice or
communication of any material noncompliance with any such Laws that has not
been cured. Each of the Managing Member, the Company and each of the
subsidiaries of the Company has all permits, licenses, trademarks, trade 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, the Company or
any subsidiary of the Company that, individually or in the 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

   (b) To the extent any one or more Reimbursable Proposals with respect to any
Participating McNeil Partnership have been approved by the Company on or prior
to the date hereof or are approved by the Company (which approval shall not be
unreasonably withheld or delayed) subsequent to the date hereof, the Company
shall make a cash contribution to such Participating McNeil Partnership, prior

to the Capital Expenditure Reimbursement for such Participating McNeil
Partnership which shall be taken into consideration in the determination of the
Excess Cash Balance of such Participating McNeil Partnership in accordance with
the Excess Cash Balance Schedule for such Participating McNeil Partnership.

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

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

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

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

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

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

   (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

Proxy Statement for such Public McNeil Partnership a Statement on

                                      A-39
<PAGE>

Schedule 13E-3 (each, a "Schedule 13E-3") with the SEC with respect to such
Public McNeil Partnership. The Company shall, upon request by Sellers, furnish
Sellers with such information concerning itself, the Managing Member and
Whitehall as may be required by law or by any Governmental Entity in connection
with any Proxy Statement, any Schedule 13E-3 or any other statement, filing,
notice or application made by or on behalf of the Company to any third party or
any Governmental Entity or both in connection with the Mergers, the MPLP
Contributions, the appointments of the applicable New GP LLCs as the successor
general partners of the McNeil Partnerships and the other transactions
contemplated by this Agreement. Sellers shall use their reasonable best efforts
to (i) promptly respond to any comments of the SEC and (ii) cause the
respective Proxy Statements to be mailed to the limited partners of the
respective Merging Partnerships as promptly as practicable after the date of
this Agreement. Sellers shall notify the Company promptly of the receipt of any
comments from the SEC and of any request by the SEC for amendments or
supplements to any Proxy Statement or any Schedule 13E-3 or for additional
information and shall supply the Company with copies of all correspondence
between Sellers or any of their representatives, on the one hand, and the SEC,
on the other hand, with respect to any Proxy Statement or any Schedule 13E-3.
The Proxy Statements for the Public McNeil Partnerships and the Schedule 13E-3s
shall comply in all material respects with all applicable requirements of law
and the rules and regulations of the SEC. Whenever any event occurs which is
required to be set forth in an amendment or supplement to any Proxy Statement,
Sellers and the Company each shall promptly inform the other of such
occurrences and Sellers shall prepare (and, in the case of the Public McNeil
Partnerships, file with the SEC) and mail to the limited partners of the
applicable Merging Partnership such amendment or supplement to such Proxy
Statement. Whenever any event occurs which is required to be set forth in an
amendment or supplement to any Schedule 13E-3, Sellers shall promptly inform
the Company of such occurrence, and Sellers and the affiliates of the
applicable Public McNeil Partnership shall file such amendment or supplement.
The Proxy Statements (at the respective dates thereof and at the dates of the
respective McNeil Limited Partner Meetings) and Schedule 13E-3s (at the
respective dates thereof) will not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; provided, however, that the foregoing
shall not apply to the extent that any such untrue statement of a material fact
or omission to state a material fact was made by Sellers in reliance upon and
in conformity with information concerning the Company or any affiliates of the
Company or concerning the Transitory Partnerships or the Company LLCs furnished
to Sellers in writing by the Company specifically for use in any such Proxy
Statements or Schedule 13E-3s.

   (b) Each Merging Partnership shall, as soon as practicable following the
date of this Agreement, subject to the time periods set forth in its
organizational documents and in applicable laws, duly call, give notice of,
convene and hold a meeting of its limited partners (a "McNeil Limited Partner
Meeting") to be held at the earliest practicable date following the date the

obtaining requisite approval by its limited partners of the Merger in respect
of such Merging Partnership, the MPLP Contributions with respect to such
Merging Partnership, the appointment of the applicable New GP LLC as the
general partner of such Merging Partnership and the other transactions
contemplated by this Agreement. Unless otherwise prohibited by law, each

regardless of whether the general partner of such Merging Partnership has
withdrawn, amended or modified its recommendation that the limited partners of
such Merging Partnership approve the Merger in respect of such Merging
Partnership, the MPLP Contributions with respect to such Merging Partnership,
the appointment of the applicable New GP LLC as the general partner of such
Merging Partnership and the other transactions contemplated by this Agreement,
unless this Agreement has been terminated in respect of such Merging
Partnership pursuant to the provisions of Section 9.3 hereof. The general
partner of each of the Merging Partnerships shall recommend to the limited
partners of such Merging Partnership approval of the Merger in respect of such
Merging Partnership, the MPLP Contributions with respect to such Merging
Partnership, the appointment of the applicable New GP LLC as the successor
general partner of such Merging Partnership and the other transactions

                                      A-40

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;

   (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, 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

                                      A-41
<PAGE>

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
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 transactions
contemplated hereby and thereby, and (B) timely making all such filings and
timely seeking all such consents, approvals, orders or 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

                                      A-42
<PAGE>

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

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

                                      A-43
<PAGE>

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

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

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

                                      A-44
<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
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.

   (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

                                      A-45
<PAGE>

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.

   Section 7.7 Ancillary Agreements.

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

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

   Section 7.8 Support Agreements; Financing.

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

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

   (c) Without limiting, amending or modifying any other provision of this
Agreement (including Sections 5.8, 8.1, 8.2 and 8.3 hereof), without the
payment of any consideration therefor, without compromising any rights and
without incurring additional liabilities or obligations, Sellers shall
cooperate with the Company to

                                      A-46
<PAGE>

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 "Board of Managers"), in an aggregate amount not to exceed one-
half of the aggregate amount of fees, expenses and disbursements charged to the
Company, its subsidiaries and affiliates by Sullivan & Cromwell with respect to
negotiating and documenting the transactions contemplated by this Agreement and
the other Transaction Documents, shall be treated as a contribution in-kind to
the Company (the "Capitalized McNeil Expenses") by MPLP (or another designee of
the Contributing Partners) in exchange for Company Interests in accordance with
Section 1.4 hereof.

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

   Section 7.11 Related Party Transactions.

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

   (b) Notwithstanding anything to the contrary in this Agreement, if
Summerhill is a Participating McNeil Partnership, the Company shall contribute
adequate cash to Summerhill to, and shall cause Summerhill to, repay at the
Effective Time (including all accrued but unpaid interest thereon through to
the Effective Time) the demand note, dated November 17, 1997, payable by
Summerhill to Robert A. McNeil and Carole J. McNeil

                                      A-47
<PAGE>

(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 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

   Section 7.14 Harbour Club.

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

   (b) Notwithstanding anything to the contrary in this Agreement, in the event
that the Company exercises its right to purchase Harbour Club I in accordance
with Section 7.14(a) hereof, the Company shall pay at the closing of such
transaction any indebtedness outstanding which is secured by Harbour Club I
(including all

                                      A-48
<PAGE>

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 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 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.


                                      A-49
<PAGE>

   (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 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).

<PAGE>

affect the value of such McNeil Partnership Property as it is being used as of
the date of this Agreement and (ii) Lawyer's Title Insurance Corporation (or

     (a) Representations and Warranties. The representations and warranties
  of the Company set forth in Article V of this Agreement shall be true and

  Date but immediately prior to the transfers of assets, rights and interests

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' 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

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

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

   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 of the CPA Firm, or, in the case of the determination of the
Financial Advisor, with the orders of the Financial Advisor or the
determination of the Financial Advisor and in either case, with this Section
11.2, then such noncomplying party shall be liable for all costs and expenses,
including attorneys' fees, incurred by a party in its effort to obtain either
an order to compel compliance with such procedures or such orders, or an
enforcement of the determination, from a court of competent jurisdiction.

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

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

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

                                   ARTICLE 1.

                                  Definitions

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

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

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

   "Agreement" shall mean this Limited Liability Company Operating Agreement,
as it may hereafter be amended or modified from time to time.

   "Annual Budget" shall mean the annual operating budget and annual capital
budget for the Company as amended from time to time, prepared by the Portfolio
Advisor for the approval of the Board of Managers pursuant to the terms of the
Portfolio Advisory Agreement and Section 4.1 hereof.

   "Appraised Value" shall mean the value determined by written agreement
between Whitehall and McNeil or, failing such an agreement within 10 days after
the appraisal procedure is commenced, (i) in the event that Whitehall and
McNeil have agreed upon an investment bank to serve as Appraiser, the value of
the non-cash consideration shall be determined by the Appraiser and (ii) in the
event that Whitehall and McNeil have requested that their respective investment
banks appoint a third investment bank to act as Appraiser, the value

                                      B-1
<PAGE>

of the non-cash consideration shall be determined by the Appraiser's

representatives.

   3.2 Managers and Officers: Number, Appointment, Removal, Qualifications,
Etc.

   (a) The total number of Managers shall at all times equal five. Whitehall
shall at all times be entitled to designate three of the five Managers (the
"Whitehall Managers") to serve until the first annual meeting of Members and
until each such Manager's successor has been elected and qualified and
Whitehall shall have the right to elect three Managers upon each annual

annual election of Managers.

   (b) No Manager may be removed from office (with or without cause) without
the consent of the Member who elected such Manager. Each Member shall have the
sole right to remove, at any time and for any reason with or without cause, any
Manager appointed by such Member and to appoint a successor Manager to fill any
vacancy caused by the removal, resignation, death or incapacity of any Manager
appointed by such Member. Each Member agrees to fill any such vacancy as soon
as practicable and agrees that it will use its best efforts to fill any such
vacancy within 30 days of such vacancy. Each Member agrees to give the Company
and the other Member prompt written notice of any appointment or removal of any
of its Managers.

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

   (d) The Board of Managers may appoint the Officers of the Company, which may
consist of, among other officers, a President, a Secretary and a Treasurer. The
Board of Managers may also appoint such other Officers

                                      B-18
<PAGE>

and agents as it shall deem necessary or advisable. All Officers and agents
shall hold their offices for such terms and shall exercise such powers and
perform such duties as shall be determined from time to time by the Board of
Managers. Any two or more offices may be held by the same person. An Officer of
the Company shall hold office until his or her successor is duly appointed and
qualified or until his or her death, resignation or removal from office. Any

without cause, by the affirmative vote of the majority of the Board of
Managers. Any vacancy occurring in any office of the Company shall be filled by
the Board of Managers.

   (e) Any Manager designated pursuant to this Section 3.2 shall assume the
powers, duties and obligations of a Manager as provided under this Agreement
and of a manager under the LLCA and shall be subject to the terms hereof and
thereof.

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

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

   3.4 Managers' Expenses. Except as agreed to between the Members, each Member
shall bear all costs incurred by the Managers designated by such Member and no
Manager shall be entitled to any compensation from the Company or its
Subsidiaries for serving in the capacity as a Manager or as the Chairman of the
Board of Managers.

   3.5 Meetings of Managers.

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

   (b) Notwithstanding anything to the contrary contained herein or in the
LLCA, subject to the proviso in Section 3.5(a), the Board of Managers shall
meet upon the request of any Whitehall Manager conveyed in writing to each
other Manager, at a time no fewer than three (3) and no more than ten (10) days
after such notice is given and at a place in New York, New York, Dallas, Texas
or such other reasonable place as is specified in such notice; provided,
however, that attendance at such meeting may be telephonic.

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

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

   (e) Unless otherwise prohibited by law, any action required or permitted to
be taken by the Board of Managers may be taken without a meeting, without prior
notice and without a vote if a consent or consents in writing, setting forth
the action so taken, shall be signed by all five of the Managers. The
resolution and the written consents thereto by the Managers shall be filed with
the minutes of the proceedings of the Board of Managers.

   3.6 Quorum. At all meetings of the Board of Managers three out of the five
Managers shall constitute a quorum for the transaction of business; provided,
however, that any Whitehall Manager shall have the right to

                                      B-19
<PAGE>

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

   3.7 Voting Requirements. When action is to be taken by vote of the Board of
Managers, each Manager shall be accorded one vote; provided, however, that any
Whitehall Manager shall have the right to represent and vote the interests of
one or both of the other Whitehall Managers and either McNeil Manager shall
have the right to represent and vote the interests of the other McNeil Manager.
Except as provided in Section 3.8, all actions of the Board of Managers must be
approved by the affirmative vote of at least three of the five Managers (a
"Majority Vote").

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

  hereof.

  foreclosure, condemnation, casualty or Bankruptcy (in each case under this

  Transaction that may be deemed to be included in the definition of Tax
  Event Transaction (which does not involve the disposition of any Commercial
  Properties).

     (c) Any Tax Event Transaction on or prior to the fifth (5th) anniversary
  of the Closing Date, other than (A) any Tax Event Transaction resulting
  from a Preferred Equity Financing Foreclosure and (B) any Tax Event

  the aggregate an amount of cash (on the date of closing of the Tax Event
  Transaction) equal to the sum of the Full Pre Lock-out Payment and the Tax
  Gross-Up Amount. The Company shall notify the holders of the McNeil
  Interest in writing of a Tax Event Transaction within two (2) business days
  of signing an agreement with respect to a Tax Event Transaction (the
  "Notice Date").

     (d) Any change in the nature of the Company's business as conducted
  immediately following the Effective Time.

     (e) Any repayment, refinancing of or amendment to any Loan Agreement,
  prior to the fifth (5th) anniversary of the Closing Date, to the extent the
  same would result in McNeil's share of "nonrecourse liabilities" (within
  the meaning of Treasury Regulation Section 1.752) and "qualified
  nonrecourse financing" (within the meaning of Section 465 of the Code)
  being less than the Initial QNL Amount.

     (f) A liquidation or dissolution of the Company except following the
  disposition of all of the Company Assets.

  the ordinary course of business with Goldman, Sachs & Co., Whitehall or
  Whitehall XI, or any Affiliate (excluding any Subsidiary of the Company) of
  any of the foregoing, other than (i) retaining Goldman, Sachs & Co. (and/or
  one or more of its Affiliates) as the Company's exclusive financial and
  sales advisor for the sale, financing, refinancing, merger, combination,

  a result of Whitehall or one or more Affiliates being the provider of
  Preferred Equity Financing.

     (l) Each of the Members hereby agrees that the Company's execution and
  delivery of the Portfolio Advisory Agreement does not require a Super-
  majority Vote.

   3.9 Role of the Portfolio Advisor and Limitations on Its Authority.

   (a) The Board of Managers shall have the right to delegate to the Portfolio
Advisor the right and duty to manage the day-to-day operational affairs of the
Company and to implement the decisions made on behalf of the Company by the
Board of Managers or any Officers in accordance with the terms of this
Agreement and applicable laws and regulations and such other rights and powers
as are granted to the Portfolio Advisor hereunder or under the Portfolio
Advisory Agreement and as the Board of Managers may from time to time expressly
delegate to the Portfolio Advisor; provided, however, that the Board of
Managers shall not delegate to the Portfolio Advisor the authority to make any
decision regarding the matters described in Section 3.1(b)(i), 3.1(b)(v),
3.1(b)(xii), 3.1(b)(xiii), 3.1(b)(xv) or 3.8 or any matter which by the terms
of this Agreement requires a Super-majority Vote or the consent of McNeil.

authorized by Whitehall in the manner set forth herein and (iii) actions

against any and all claims, demands, losses, damages, liabilities, lawsuits and

not limited to, reasonable attorneys' fees) arising, directly or indirectly, in
whole or in part, out of any breach of the provisions of this Section 3.9(b) by
McNeil or any McNeil Manager.

<PAGE>

Company a reasonable fee, in accordance with market rates (including in respect
of commissions and fees) and terms, in exchange for such services.

   The Members covenant and agree that:

     (i) the Company will exclusively retain Goldman, Sachs & Co. (as well as
  such Affiliate(s) as Goldman, Sachs & Co. may designate from time to time)
  to provide sales advisory services to the Company in connection with any
  sale, merger, combination, disposition or similar transaction involving the

Affiliate(s)) shall be entitled to receive from the Company fees and
commissions for such services in accordance with market rates and terms and
indemnification in accordance with market terms for comparable services
rendered by comparable firms.

the fact that a Member, an Affiliate of a Member, or any officer, director,
employee, partner, consultant or agent of a Member, is directly or indirectly
interested in or connected with any Person employed by the Company to render or
perform a service shall not prohibit the Company from employing such Person on
an arm's length basis and at market rates (including in respect of commissions
and fees) and terms, and neither the Company nor any of the other Members shall
have any right in or to any income or profits derived therefrom by reason of
this Agreement.

   4.6 Use of Company Property. No Member shall make use of the funds or
property of the Company or its Subsidiaries, or assign its rights to specific
property, other than for the business or benefit of the Company or its
Subsidiaries.

   4.7 Designation of Tax Matters Member. The Tax Matters Member shall act as
the "tax matters partner" of the Company, as provided in the regulations
pursuant to Section 6231 of the Code. Each Member hereby approves of such
designation and agrees to execute, certify, acknowledge, deliver, swear to,
file and record at the appropriate public offices such documents as may be
deemed necessary or appropriate to evidence such approval. To the extent and in
the manner provided by applicable Code sections and regulations thereunder, the
Tax Matters Member (a) shall furnish the name, address, profits interest and

each Member of administrative or judicial proceedings for the adjustment of
Company items required to be taken into account by a Member for income tax
purposes. Each Member hereby reserves all rights under applicable law with
respect to the activities undertaken by the Tax Matters Member, including the
right to retain independent counsel of its choice at its expense. The Company
shall indemnify the Tax Matters Member for any liabilities incurred in such
capacity.

   4.8 Proposed Transactions After Five Years.

   (a) In the event of any Proposed Change of Control Transaction that is
proposed to be consummated after the fifth (5th) anniversary of the Closing
Date, then Whitehall shall give McNeil written notice of the Proposed Change of
Control Transaction and McNeil shall be "cashed-out" upon the consummation of
such Proposed Change of Control Transaction. In exchange for all of the McNeil
Interest, the holders of the McNeil Interest

                                      B-23
<PAGE>

shall be paid in the aggregate an amount in cash equal to the Full Post Lock-
out Payment upon the closing of such Proposed Change of Control Transaction.

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

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

     (ii) Except as provided in Section 4.8(b)(iii), Whitehall shall
  determine the value of any non-cash consideration to be received by the
  Members in any Proposed Company Transaction and if Whitehall determines
  that the value of such non-cash consideration plus any cash consideration
  to be received by the holders of the McNeil Interest is sufficient to
  provide to the holders of the McNeil Interest a Full Post Lock-out Payment,
  the holders of the McNeil Interest shall have the right to either (i)
  exchange all of the McNeil Interest upon the closing of such Proposed
  Company Transaction for such cash and non-cash consideration having a value
  (using Whitehall's valuation) equal to the Full Post Lock-out Payment, or
  (ii) exchange all of the McNeil Interest upon the closing of such Proposed
  Company Transaction for cash in an amount equal to the Full Post Lock-out
  Payment. McNeil shall have the right to engage, at the sole expense of the
  holders of the McNeil Interest, an investment bank or other appraiser to
  assist the holders of the McNeil Interest in determining whether to take
  the non-cash consideration or the cash.

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

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

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

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

Managers shall have the authority to obtain, on behalf of the Company and its

Sachs & Co. and/or its Affiliates (as lender) at market rates and terms and/or
from any other non-affiliated lender as the Board of Managers in good faith
deems appropriate.

may include Archon. For the Commercial Properties, the Board of Managers will

binding on the Company and the Members and shall be adhered to by the Company
and the Members for the purposes of reporting the book and tax basis of the
Company Assets.

construed to) constitute a waiver by any Member of its rights under applicable
law and its right to retain independent counsel of its choice at such Member's
expense.

cause the Company to take, any and all reasonable actions to ensure that the

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

   (a) Each of the Members covenants and agrees to make an Additional Capital
Contribution to the Company in accordance with such Member's Percentage
Interest, determined immediately prior to the making by any Member of any
Additional Capital Contribution pursuant to this Section 4.16(a), to fund the

                                      B-25
<PAGE>

asset. If either Member shall fail to make its required Capital Contribution
pursuant to this Section 4.16(a), the other Member may purchase Harbour Club
Phase Four directly and not through the Company.

   (b) In the event that the Company exercises its option to purchase Harbour
Club Phase One, pursuant to Section 7.14 of the Master Agreement, each of the
Members covenants and agrees to make an Additional Capital Contribution to the
Company in accordance with such Member's Percentage Interest, determined
immediately prior to the making by any Member of any Additional Capital
Contribution pursuant to this Section 4.16(b), to fund the purchase price of
Harbour Club Phase One. The Additional Capital Contribution made by McNeil

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

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

                                      B-26
<PAGE>

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

   6.2 Working Capital Contributions and Other Additional Capital
Contributions.

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

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

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

   (d) Notwithstanding anything to the contrary in this Agreement, if a Member
shall guarantee any indebtedness of the Company, such Member shall not receive
any credit to its Capital Account as a result of such guarantee and such
guarantee shall not be considered to be a Capital Contribution unless, and only
to the extent that, such Member makes a payment in respect of that guarantee
and such payment is not immediately reimbursed by the Company.

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

   6.4 Distributions as Working Capital Reserves. Notwithstanding anything to
the contrary contained herein, if Whitehall would otherwise be entitled to
receive a cash distribution of Net Cash Flow or Net Proceeds from Capital
Transactions pursuant to Section 8.1(b) or 8.1(c) from the Company, Whitehall
may elect to forego receipt of all or a portion of such distribution and have
the amount so foregone treated as part of the Initial Working Capital
Contribution (or, after the Initial Working Capital Contribution has been
funded in full, as an Additional Capital Contribution; provided the Board of
Managers shall have determined in good

                                      B-28
<PAGE>

faith (by Majority Vote) that such Capital Contribution is required for use by
the Company within a reasonable period of time following the date upon which
such distribution of cash would otherwise have been made to Whitehall. In such
event Whitehall will be treated as if it had (i) received distributions equal
to the amount it would have received pursuant to Section 8.1(b) or 8.1(c) had
Whitehall not foregone such distribution and (ii) made an Additional Capital
Contribution in such amount (any such Additional Capital Contribution shall
first be treated as part of the Initial Working Capital Contribution until the
Initial Working Capital Contribution has been fully funded).

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

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

     (ii) Whitehall may elect to treat the Funded Portion as a loan (a
  "Partner Loan") by Whitehall to McNeil, which Partner Loan shall be treated
  as (i) a demand loan made by Whitehall to McNeil (bearing interest at 20%
  per annum, compounded annually) followed by (ii) a Capital Contribution by
  McNeil to the Company. Any such Partner Loan (to the extent of unpaid
  principal and interest) shall be recourse only to the McNeil Class A
  Interest and shall be repaid directly by the Company on behalf of McNeil
  from amounts otherwise distributable to McNeil pursuant to Section 8.1 or
  10.3 hereof. Any such distributions used to repay such Partner Loan shall
  be applied first to accrued but unpaid interest and then to principal of
  the Partner Loan. Whitehall may, at any time prior to the full repayment of
  such Partner Loan, elect to terminate such Partner Loan and have the McNeil
  Class A Investment, McNeil's Percentage Interest and, at the election of
  Whitehall, McNeil's Capital Account diluted as set forth in Section 6.5(b)
  below, with the amount of the entire outstanding principal and accrued but
  unpaid interest (as of the date of such termination) of the Partner Loan
  treated as the amount of the Funded Portion and not as a Capital
  Contribution of McNeil, and the McNeil Class A Investment, the Whitehall
  Class A Investment, the McNeil and Whitehall Percentage Interests and, at
  the election of Whitehall, the McNeil and Whitehall Capital Accounts,
  adjusted accordingly.

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

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

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

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


                                      B-29

   6.6 Limited Liability of Members. No Member shall be bound by, nor be
personally liable for, the expenses, liabilities, indebtedness or obligations
of the Company. The liability of each Member shall be limited solely to the
amount of its Capital Contribution; provided, however, that after a Member has
received a distribution from the Company, such Member may be liable to the
Company for the amount of the distribution but only to the extent required by
Section 18-607 of the LLCA.

                                   ARTICLE 7.

              Capital Accounts, Profits and Losses and Allocations

   7.1 Capital Accounts

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

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

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

   7.2 Profits and Losses.

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

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

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

   (d) For all purposes, including federal, state and local income tax
purposes, Profits shall be allocated in each Fiscal Year among all the Members
pursuant to this Section 7.2(d) for the current period (i) first, to the

                                      B-30
<PAGE>

holders of the Whitehall Class B Interest in an amount equal to the
distributions made pursuant to Sections 8.1(b)(i) and 8.1(c)(ii) and (ii)
thereafter, in proportion to the aggregate distributions of cash paid to such
Member in respect of such period. In no instance, however, shall McNeil or any
Affiliate of McNeil be allocated Profits in a given year greater than the cash
distributed to them during that year.

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

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

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

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

     (iii) In the event any Member unexpectedly receives any adjustments,
  allocations or distributions described in Treasury Regulations Sections
  1.704-(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall
  be specially allocated to each such Member in an amount and manner
  sufficient to eliminate, to the extent required by the Treasury
  Regulations, the deficit of such Member's Capital Account (as determined
  under Treasury Regulations Section 1.704-1) as quickly as possible,
  provided that an allocation pursuant to this subsection 7.2(f)(iii) shall
  be made only if and to the extent that such Member would have such Capital
  Account deficit after all other allocations provided for in Section 7.2
  have been tentatively made as if this subsection 7.2(f)(iii) were not in
  this Agreement.

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

     (v) Notwithstanding the allocations provided for in sub-section (i) of
  this Section 7.2(f) and Sections 7.2(d) and (e), if there is a net increase
  in Minimum Gain of the Company during a taxable year of the Company that is
  attributable to Member-Funded Debt then first Depreciation, to the extent

   (a) Whitehall and any Transferee of any of the Whitehall Interest pursuant
to this Section 9.1(a) shall have the right to Transfer all or any portion of
its Interest to (i) any Affiliate of Whitehall (provided such Person at all
times remains an Affiliate of Whitehall), or (ii) to any other Person upon

Interests shall be made explicitly subject to the Indemnification Agreement.

   (c) Except as provided in Sections 9.1(a) and (b), all Transfers are
prohibited. Any purported Transfer in violation of this Article 9 shall be void

   9.2 Transfer Binding on Company.

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

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

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

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

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

   (b) Notwithstanding anything to the contrary contained in this Agreement, no

Managers shall have the right to prohibit and may refuse to accept any
Transfer, unless: (i) registration is not required under the Securities Act of
1933, as amended, in respect of such Transfer; (ii) such Transfer does not
violate any applicable federal or state securities, real estate syndication, or
comparable laws; (iii) such Transfer will not be subject to, or such Transfer,
when aggregated with prior Transfers will not result in the imposition of, any
state, city or local transfer taxes, including, without limitation, any
transfer gains taxes, unless such transferor pays such taxes; and (iv) such
Transfer will not cause the Company to be treated as a "publicly-traded
partnership" within the meaning of Section 7704 of the Code. The Board of
Managers may elect prior to any Transfer to require an opinion of counsel with
respect to any of the foregoing matters.

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

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

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

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

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

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

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

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

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

Secretary of State of the State of Delaware under Section 18-203 of the LLCA.

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

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

   12.7 WAIVER OF JURY TRIAL. EACH OF THE MEMBERS (ON BEHALF OF ITSELF, ITS
AFFILIATES, AND THE HOLDERS OF INDIRECT AND DIRECT BENEFICIAL INTERESTS IN

                                      B-38
<PAGE>

ITSELF) AND THE COMPANY, HAVING CAREFULLY CONSIDERED THE ISSUE, AND HAVING
SOUGHT AND OBTAINED THE ADVICE OF COUNSEL, KNOWINGLY, INTENTIONALLY AND
IRREVOCABLY WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY CLAIM OR
PROCEEDING RELATED TO OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY.

   12.8 Consent to Jurisdiction. Each Member and the Company hereby irrevocably
consents and agrees, for the benefit of each Member, that any legal action,
suit or proceeding against it with respect to its obligations, liabilities or
any other matter under or arising out of or in connection with this Agreement
and with respect to the enforcement, modification, vacation or correction of an
award rendered in an arbitration proceeding may be brought in any federal or
state court located in New York City (each a "New York Court"), and hereby
irrevocably accepts and submits to the exclusive jurisdiction of each such New
York Court, as the case may be, with respect to any such action, suit or
proceeding. Each Member and the Company hereto waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid
actions, suits or proceedings brought in any such New York Court and hereby
further waives and agrees not to plead or claim in any such New York Court that
any such action, suit or proceeding brought therein has been brought in an
inconvenient forum.

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

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

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

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

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

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

   12.15 Maintenance as a Separate Entity. The Company shall maintain books and
records and bank accounts separate from those of its Affiliates (other than the
Company's Subsidiaries); shall at all times hold

                                      B-39
<PAGE>

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

   12.16 Confidentiality.

   (a) The Members agree not to disclose or permit the disclosure of any of the
terms of this Agreement or of any other confidential, non-public or proprietary

provided that such disclosure may be made (i) to any Person who is a partner,
officer, director or employee of such Member or counsel to or accountants of
such Member solely for their use and on a need-to-know basis, provided that
such Persons are notified of the Members' confidentiality obligations
hereunder, (ii) with the prior written consent of Whitehall, (iii) subject to
Section 12.16(b), pursuant to a subpoena or order issued by a court, arbitrator
or governmental body, agency or official, (iv) to any lender providing
financing to the Company, or (v) if in the opinion of counsel to the Member
seeking to disclose such Confidential Information, such disclosure is required
under the federal securities laws or the rules of regulation of any relevant
exchange.

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

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

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

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

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

   12.20 Non-Recourse.

   (a) Whitehall (on behalf of itself and the other Company Persons)
acknowledges and agrees that notwithstanding anything to the contrary in this
Agreement or under applicable law: (i) this Agreement shall not create or be
deemed to create or permit any liability or obligation on the part of any
McNeil Person, and no McNeil Person shall be bound or have any liability
hereunder; and (ii) any and all Company Persons shall look solely to the assets
of McNeil for satisfaction of any liability of McNeil under this Agreement, and
no Company Person shall seek recourse or commence any action against any McNeil
Person's assets, for the performance or payment of any obligation of McNeil
under this Agreement. Whitehall (on behalf of itself and the other Company
Persons) acknowledges and agrees that the Company Persons have conducted their
own independent review and analysis of the business, operations, technology,
assets, liabilities, results of operations, financial condition and prospects
of the business of the McNeil Partnerships and acknowledge that they have
received access to certain personnel, properties, premises and books and
records of such business for this purpose. In entering into this Agreement,
Whitehall has relied solely upon its own investigation and analysis and the
specific representations and warranties of McNeil made in this Agreement, and
(i) acknowledges that, except for the specific representations and warranties
of McNeil contained in this Agreement, neither McNeil nor any other McNeil
Person makes or has made any representation or warranty, either express or
implied, as to the accuracy or completeness of any of the information
(including any projections, estimates or other forward-looking information)
provided (including in any management presentations, information memorandum,
supplemental information or other materials or information with respect to any
of the above) or otherwise made available to Company Persons in connection with
the transactions contemplated by this Agreement and (ii) agrees, to the fullest
extent permitted by law, that: (i) none of the McNeil Persons shall have any
liability or responsibility whatsoever to any Company Person under this
Agreement on any basis (including in contract or tort, under federal or state
securities laws or otherwise) based upon any information provided or made
available, or statements made (or any omissions therefrom), to any Company
Person in connection with the transactions contemplated by this Agreement; and
(2) that McNeil shall not have any liability or responsibility whatsoever to
any Company Person under this Agreement on any basis (including in contract or
tort, under federal or state securities laws or otherwise (other than fraud or
willful misrepresentation)) based upon any information provided or made
available, or statements made (or any omissions therefrom), to any Company
Person in connection with the transactions contemplated by this Agreement,
except as and only to the extent expressly set forth in this Agreement and
subject to any limitations and restrictions contained in this Agreement.

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

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

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

   Gentlemen:

   The general partners (the "General Partners") of the above identified
partnerships (the "Partnerships") have advised us that the Partnerships are
contemplating a transaction (the "Transaction") pursuant to an agreement (the
"Master Agreement") in which WXI/McN Realty, L.L.C., a newly formed Delaware
limited liability company (the "Company"), will acquire (i) the general
partnership interests in each of the Partnerships and certain rights and assets
relating thereto (collectively, the "General Partner Interests"), (ii) the
limited partnership interests in each of the Partnerships (the "Limited Partner
Interests") and (iii) the assets of McNeil Real Estate Management, Inc. and
certain rights relating thereto (collectively, the "McREMI Assets"), in
exchange for cash and membership interests in the Company ("Membership
Interests") and the prepayment and assumption of indebtedness of the
Partnerships and their subsidiaries (collectively, the total cash, Membership
Interests and the aggregate amount of indebtedness being prepaid or assumed are
referred to herein as the "Aggregate Consideration"). The Aggregate
Consideration will approximate $644,440,000. Capitalized terms used but not
defined herein have the meanings ascribed to such terms in the Master
Agreement.

   We understand that, pursuant to the terms of the Master Agreement, the
parties to the Master Agreement have agreed to allocate the Aggregate
Consideration between certain assets of McREMI (the "Partial McREMI Allocated
Value"), on the one hand, and all of the Partnerships taken as a whole
(collectively, the "Total Allocated Partnership Value"), on the other hand,
pursuant to an Allocation Analysis (the "Allocation Analysis") prepared by
Robert A. Stanger & Co., Inc. ("Stanger"). We understand that the Total
Allocated Partnership Value will be allocated among the individual Partnerships
pursuant to the terms of the Master Agreement (the portion of the Total
Allocated Partnership Value allocated to each Partnership, the "Per Partnership
Allocated Value" for such Partnership). In rendering the Allocation Analysis,
the Per Partnership Allocated Value will be reduced by the aggregate amount of
indebtedness of such Partnership (the "Net Per Partnership Allocated Value").
We understand that, pursuant to the terms of the Master Agreement, the parties
to the Master Agreement have agreed to allocate the Net Per Partnership
Allocated Value of each Partnership among the General Partner Interests in each
Partnership (which shall include a further allocation between the proportional
interest in such Partnership based upon capital contributions and each of the
rights and other assets corresponding to such Partnership which are being
contributed in connection with such interests in accordance with Article II of
the Master Agreement), the amounts due to McREMI (the "Second McREMI Allocated
Value"), and each class of Limited Partner Interests in such Partnership (the
"Limited Partner Consideration Amount"). We understand that the Master
Agreement contemplates a special payment to Limited Partners of each
Partnership at or around the closing date of the Transaction in an amount equal
to the estimated working capital balance as of such date (the "Excess Cash
Balance"). The Excess Cash Balance and the Limited Partner Consideration Amount
of each Partnership will be paid to holders of Limited Partner Interests of
each Partnership based upon the provisions of the partnership agreement of each
Partnership relating to a liquidation.

                                     C-1-1
<PAGE>

   We understand that limited partners in each of the Partnerships will have
the opportunity to approve or reject the participation by their Partnership in
the Transaction pursuant to a proxy statement and a limited partners meeting
which will be prepared and held, respectively, in connection with the
Transaction, and further that limited partners in each Partnership (except
Fairfax Associates II, Ltd. ("Fairfax") and McNeil Summerhill I, L.P.
("Summerhill")), will receive only cash in exchange for Limited Partner
Interests. We understand that affiliates of the General Partners are expected
to contribute assets to the Company in connection with the Transaction
(including the General Partner Interests in each of the Partnerships, the
Limited Partner Interests in Fairfax and Summerhill, the McREMI Assets and
additional cash) with an aggregate value range of $60 million to $100 million,
representing approximately 28.0% to 46.7% of the initial mezzanine debt and
equity capitalization of the Company.

   You have requested that Stanger provide an opinion as to the fairness, from
a financial point of view, to the holders of each class of Limited Partner
Interests in each Partnership of: (i) the Aggregate Consideration to be paid
for the McREMI Assets and the Limited Partner Interests and General Partner
Interests in the Partnerships in connection with the Transaction; (ii) the
allocation of the Aggregate Consideration between the Partial McREMI Allocated
Value, on the one hand, and the Total Allocated Partnership Value, on the other
hand; (iii) the Per Partnership Allocated Value for each Partnership; (iv) the
methodology of allocation of the Per Partnership Allocated Value, less
indebtedness prepaid or assumed, among the General Partner Interests, the
Second McREMI Allocated Value and each class of Limited Partner Interests; and
(v) the estimated per unit Excess Cash Balance and Limited Partner
Consideration Amount with respect to each class of Limited Partner Interest for
each Partnership determined as of March 31, 1999, based upon the balance sheet
of each Partnership as of such date adjusted for transaction expenses and the
allocation thereof, as estimated by the General Partner.

   Stanger, founded in 1978, has provided research, investment banking and
consulting services to clients located throughout the United States, including
major New York Stock Exchange member firms and insurance companies and over
seventy companies engaged in the management and operation of partnerships and
real estate investment trusts. The investment banking activities of Stanger
include financial advisory services, asset and securities valuations, industry
and company research and analysis, litigation support and expert witness
services, and due diligence investigations in connection with both publicly
registered and privately placed securities transactions.

   Stanger, as part of its investment banking business, is regularly engaged in
the valuation of businesses and their securities in connection with mergers,
acquisitions, and reorganizations and for estate, tax, corporate and other
purposes. In particular, Stanger's valuation practice principally involves
partnerships, partnership securities and the assets typically owned through
partnerships including, but not limited to, real estate, mortgages secured by
real estate, oil and gas reserves, cable television systems, and equipment
leasing assets.

   In arriving at the opinion set forth below, we have:

  . Reviewed the most recently available draft of the Master Agreement and
    the First Amended and Restated Limited Liability Company Operating
    Agreement of WXI/McN Realty L.L.C.;

  . Reviewed the financial statements of the Partnerships for the years ended
    December 31, 1997 and 1998 and the three months ended March 31, 1999;

  . Reviewed information provided by McREMI, as property manager, the General
    Partners and the Partnerships for each property (the "Property" or
    "Properties") owned by the Partnerships including: property description,
    rentable square footage, unit mix, year built, historical and projected
    operating statements, rent rolls, tenant improvement allowances, expense
    reimbursements, tax information, capital expenditure estimates, deferred
    maintenance estimates, and estimates of costs to remediate environmental
    conditions;

  . Conducted site inspections of each Property and discussed with management
    of McREMI, the General Partners and the Partnerships the conditions in
    local rental markets and market conditions for sales and acquisitions of
    properties of the type owned by the Partnerships and the historical
    financial statements and budgeted and projected operations of the
    Properties;

                                     C-1-2
<PAGE>

  . Reviewed surveys of competing properties prepared by or on behalf of
    McREMI, the General Partners and the Partnerships, including rental
    rates, vacancies, and tenant improvement allowances;

  . Reviewed information on acquisition criteria used by real estate
    investors for properties similar to the Properties during 1999;

  . Reviewed the financial statements of McREMI and its affiliates for the
    years ended December 31, 1997 and 1998 and the three months ended March
    31, 1999;

  . Interviewed PaineWebber Incorporated regarding the conduct of the bid
    solicitation process relating to the Transaction; and

  . Conducted such other studies, analyses, inquiries and investigations as
    we deemed appropriate.

   In rendering this opinion, we have relied, without independent verification,
on the accuracy and completeness in all material respects of all financial and
other information that was furnished or otherwise communicated to us by McREMI,
the General Partners and the Partnerships. We have not performed an independent
appraisal of the assets and liabilities of the Partnerships or the McREMI
Assets. We have not conducted any engineering studies and have relied on the
estimates of the management of McREMI with respect to deferred maintenance and
the estimated cost to remediate environmental conditions for each Property. We
have not reviewed any proxy statement prepared in connection with the
Transaction as one was not available on the date hereof.

   We have relied on the assurance of McREMI, the General Partners and the
Partnerships, that: (i) the Property budgets and discounted cash flow analyses
provided to us were in the judgment of McREMI, the General Partners and the
Partnerships reasonably prepared on bases consistent with actual historical
experience and reflect the best currently available estimates and good faith
judgments; (ii) any estimates of costs to remediate environmental conditions
are adequately considered in the capital expenditure estimates provided to us
and that no additional environmental conditions are present at the Properties;
(iii) any historical financial data, balance sheet data, transaction cost
estimates and estimates of the deficit restoration obligation of the general
partner which would be due upon a liquidation are accurate in all material
respects; (iv) no material changes have occurred in the information reviewed or
in the value of the Properties or the McREMI Assets between the date the
information was provided to us and the date of this letter; and (v) McREMI, the
General Partners and the Partnerships are not aware of any information or facts
regarding the Partnerships, the Properties, the McREMI Assets or the Company
that would cause the information supplied to us to be incomplete or misleading
in any material respect.

   We did not determine or negotiate the amount or form of the Aggregate
Consideration. We have not been requested to, and therefore do not: (i) make
any recommendation to McREMI, the General Partners or the Limited Partners with
respect to whether to approve or reject the Transaction; or (ii) express any
opinion as to (a) the impact of the Transaction with respect to McREMI, the
General Partners or the Limited Partners of any Partnership that does not
participate in the Transaction; (b) the tax consequences of the Transaction for
McREMI, the General Partners or the Limited Partners of any Partnership; (c)
the Company's ability to qualify as a McNeil Partnership or real estate
investment trust, or the consequences of the Company's failure to so qualify;
(d) the potential capital structure of the Company or its impact on the
financial performance of the Membership Interests; (e) the Company's ability to
finance its obligations pursuant to the Master Agreement or the impact of a
failure to obtain financing on the financial performance of the Company or the
Partnerships; (f) whether or not alternative methods of determining or
allocating the Aggregate Consideration to be received by the General Partners,
Limited Partners of the Partnerships or McREMI would have also provided fair
results or results substantially similar to those of the methodology to be
used; (g) alternatives to the Transaction; or (h) any other terms of the
Transaction other than the Aggregate Consideration and the allocation thereof.
Furthermore, we are not expressing any opinion herein to Robert A. McNeil or
Carole McNeil in their capacities as direct or indirect holders of General or
Limited Partner Interests in the Partnerships or McNeil Partners, L.P. or of
capital stock in McREMI. Further, we are not expressing any opinion herein as
to the

                                     C-1-3
<PAGE>

fairness of any terms of the Transaction other than as described herein,
including without limitation: (i) the fairness of the amounts or allocations of
Transaction costs, or (ii) the prices at which the Membership Interests in the
Company may trade, if at all, following the Transaction, or the trading value
of the Membership Interests compared with the current fair market value of any
assets contributed to the Company in connection with the Transaction if the
Company were to be liquidated in the current real estate market.

   This letter does not purport to be a complete description of the analyses
performed or the matters considered in rendering our opinion. The analyses and
the summary set forth herein must be considered as a whole, and selecting
portions of such summary or analyses, without considering all factors and
analyses, would create an incomplete view of the processes underlying this
opinion. In rendering this opinion, judgment was applied to a variety of
complex analyses and assumptions. The assumptions made and the judgments
applied in rendering the opinion are not readily susceptible to partial
analysis or summary description. The fact that any specific analysis is
referred to herein is not meant to indicate that such analysis was given
greater weight than any other analysis.

   Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter, each of the matters set forth in the following clauses (i)
through (v) is fair from a financial point of view to the holders of each class
of Limited Partner Interests in each Partnership: (i) the Aggregate
Consideration to be paid for the McREMI Assets and the Limited Partner
Interests and General Partner Interests; (ii) the allocation of the Aggregate
Consideration between the Partial McREMI Allocated Value, on the one hand, and
the Total Allocated Partnership Value, on the other hand; (iii) the Per
Partnership Allocated Value; (iv) the methodology of allocation of the Per
Partnership Allocated Value, less indebtedness prepaid or assumed, among the
General Partner Interests, the Second McREMI Allocated Value and each class of
Limited Partner Interest; and (v) the estimated per unit Excess Cash Balance
and Limited Partner Consideration Amount with respect to each class of Limited
Partner Interest for each Partnership determined as of March 31, 1999, based
upon the balance sheet of each Partnership as of such date adjusted for
transaction expenses and the allocation thereof, as estimated by the General
Partners.

   This letter and the opinions set forth herein were delivered pursuant to the
Amended and Restated Agreement, dated as of May 7, 1999, between Stanger and
the Partnerships and, in accordance with such agreement, Stanger acknowledges
that further letters, allocations and opinions shall be delivered to the
Partnerships subsequent to the date hereof in accordance with the terms of such
agreement, including with respect to the matters described in the following
paragraph.

   It is our understanding that, at or around the date the preliminary proxy
statements are submitted to the Securities and Exchange Commission ("SEC") for
review, the Excess Cash Balance and the allocation of the Per Partnership
Allocated Value, less indebtedness prepaid or assumed, among the General
Partner Interests, the Second McREMI Allocated Value and each class of Limited
Partner Interests for each of the Partnerships will be redetermined to reflect
the operation of the Partnerships and related changes in working capital during
such period and that Stanger will be requested to render an opinion as to the
fairness from a financial point of view to the Limited Partners of each
Partnership of the allocation of the Per Partnership Allocated Value, less
indebtedness prepaid or assumed, among the General Partner Interests, the
Second McREMI Allocated Value and each class of Limited Partner Interests of
such Partnership in connection with the Transaction.

Yours truly,

Special Committee of the Board of Directors
of McNeil Investors, Inc.
c/o Paul B. Fay, Jr.
3766 Clay Street
San Francisco, CA 94118

Dear Mr. Fay:

   We have been engaged pursuant to an Agreement dated as of May 7, 1999 (the
"Agreement") by the Special Committee of the Board of Directors of McNeil
Investors, Inc. (the "Committee") to render certain opinions in connection with
the proposed transaction (the "Transaction") whereby a newly formed Delaware
limited liability company (the "Company") to be owned by Robert A. McNeil and
Carole J. McNeil (and/or affiliates thereof) and Whitehall Street Real Estate
Limited Partnership XI (and/or affiliates thereof) shall, in exchange for
ownership interests in such entity (the "Membership Interests"), cash and the
assumption of certain indebtedness (collectively, the "Aggregate
Consideration"), acquire (i) all of the general partnership interests of the
Partnerships listed on Appendix I hereto (the "Partnerships"), and certain
rights and assets related thereto (the "General Partner Interests"), (ii) all
of the limited partnership interests of the Partnerships (the "Limited Partner
Interests") and (iii) certain of the assets of McNeil Real Estate Management,
Inc. and certain rights related thereto (the "McREMI Assets"), in each case,
pursuant to a Master Agreement (the "Master Agreement"). The Aggregate
Consideration specified in the Master Agreement is approximately $644,440,000.
The Partnerships and Robert A. Stanger & Co., Inc. ("Stanger") have entered
into an Amended and Restated Agreement dated as of May 7, 1999 (the "Stanger
Agreement"), whereunder Stanger has agreed to render to the Partnerships
certain allocations and opinions, all as more fully contemplated in Sections 1
and 2 of the Stanger Agreement.

   Pursuant to the terms of the Master Agreement, the allocation of the
Aggregate Consideration between certain assets of McREMI (the "Partial McREMI
Allocated Value"), on the one hand, and all of the Partnerships, taken as a
whole (the "Total Allocated Partnership Value"), on the other hand, has been
made pursuant to an Allocation Analysis dated June 24, 1999 (the "Allocation
Analysis") prepared by Stanger. The Allocation Analysis also reflects the
allocation of the Total Allocated Partnership Value among the individual
Partnerships (the portion of the Total allocated Partnership Value allocated to
each Partnership, the "Per Partnership Allocated Value" for such Partnership,
and the Per Partnership Allocated Value for each Partnership reduced by the
aggregate amount of indebtedness of such Partnership, the "Net Per Partnership
Allocated Value"). Pursuant to the terms of the Master Agreement, the
allocation of the Net Per Partnership Allocated value of each Partnership among
the General Partner Interests in such Partnership (which shall include a
further allocation between the proportional interest in such Partnership based
upon capital contributions and each of the rights and other assets
corresponding to such Partnership which are being contributed in connection
with such interests in accordance with Article II of the Master Agreement,
including the amounts due to McREMI (the "Second McREMI Allocated Value")) and
each class of Limited Partner Interests in such Partnership (the "Limited
Partner Consideration Amount") will be made by Stanger. The Allocation Analysis
contains the methodology to be used by Stanger to determine the allocation
described in the preceding sentence and reflects a preliminary allocation of
such amounts as of March 31, 1999. As set forth in the Stanger Opinion this

                                     D-1-1
<PAGE>

allocation will be updated prior to the closing of the Transaction. We
understand that the Master Agreement contemplates a special payment to Limited
Partners of each Partnership (the "Limited Partners") at or around the closing
date of the Transaction in an amount equal to the estimated working capital
balance as of such date (the "Excess Cash Balance"). The Excess Cash Balance
of, and the Limited Partner Consideration Amount allocable to, each class of
Limited Partners of each Partnership will be paid to such Limited Partners
based upon the provisions of the partnership agreement of such Partnership
relating to a liquidation.

   We understand that the Limited Partners in each of the Partnerships will
have the opportunity to approve or reject the participation by their
Partnership in the Transaction pursuant to a proxy statement and a Limited
Partners meeting which will be prepared and held, respectively, in connection
with the Transaction, and further that limited partners in each Partnership
(except Fairfax Associates II, Ltd. ("Fairfax") and McNeil Summerhill I, L.P.
("Summerhill")), will receive exclusively cash in exchange for Limited Partner
Interests. We understand that affiliates of the General Partners are expected
to contribute assets to the Company in connection with the Transaction
(including the General Partner Interests in each of the Partnerships, the
Limited Partner Interests in Fairfax and Summerhill, the McREMI Assets and
additional cash) with an aggregate value range of $60 million to $100 million,
representing approximately 28.0% to 46.7% of the initial mezzanine debt and
equity capitalization of the Company.

   Pursuant to the Stanger Agreement, Stanger has delivered the Allocation
Analysis and its opinion dated June 24, 1999 (the "Stanger Opinion") as to the
fairness, from a financial point of view, to the holders of each class of
Limited Partnership Interests in each Partnership of: (i) the Aggregate
Consideration to be paid for the McREMI Assets and the Limited Partner
Interests and General Partner Interests in connection with the Transaction;
(ii) the allocation of the Aggregate Consideration between the Partial McREMI
Allocated Value, on the one hand, and the Total Allocated Partnership Value, on
the other hand; (iii) the Per Partnership Allocated Value for each Partnership;
(iv) the methodology of allocation of the Net Per Partnership Allocated Value
of each Partnership among the General Partner Interests, the Second McREMI
Allocated Value and each class of Limited Partner Interests of such
Partnership; and (v) the estimated per unit Excess Cash Balance and Limited
Partner Consideration Amount with respect to each class of Limited Partner
Interests for each Partnership determined as of March 31, 1999, based upon the
balance sheet of each Partnership as of such date adjusted for transaction
expenses and the allocation thereof, as estimated by the General Partners of
each Partnership (the "General Partners").

   The qualifications of and experience of Stanger and the bases for the
conclusions reached in the Allocation Analysis and the Stanger Opinion are
included in the Allocation Analysis and the Stanger Opinion.

   Stanger was retained by the Partnership on January 12, 1998 for the purpose
of conducting a valuation analysis of the Partnerships. The Allocation Analysis
and the Stanger Opinion provide a summary description of the activities of
Stanger during the period of its engagement by the Partnerships. We were
retained by the Special Committee on May 7, 1999 and by agreement with the
Special Committee the scope of our involvement with respect to the matters
covered by the Allocation Analysis and the Stanger Opinion has been
considerably more narrow than that of Stanger.

   Founded in 1967, we are a private real estate investment banking firm that
specializes in the structuring and placement of debt and equity capital for
institutional grade real estate assets. Headquartered in New York City, we have
offices in Chicago, Dallas, and Los Angeles. Our aggregate transaction
experience exceeds $125 billion and encompasses all of the major United States
markets. Since January 1998, we have completed transactions with a value of
$14.4 billion which include 61 million square feet of office properties, 18.5
million square feet of retail properties, 17,000 apartment units, and 11,700
hotel rooms.

   You have requested that we deliver our opinions that:

     (i) the Allocation Analysis and Stanger Opinion are based upon the
  application of appropriate methodologies and that the factual bases
  utilized by Stanger in the application of such methodologies have a
  reasonable basis,

                                     D-1-2
<PAGE>

     (ii) the conclusions reached in the Allocation Analysis and Stanger
  Opinion have a reasonable basis, and

     (iii) the Special Committee is entitled to rely upon such conclusions.

   You have also requested that we deliver our opinion, based on our limited
review, as more fully set forth in this letter, as to the fairness, from a
financial point of view to the holders of each class of Limited Partnership
Interests in each of the Partnerships, of each of the matters specified in
clauses (i) through (v) of the final paragraph on page 5 of the Stanger
Opinion.

   In arriving at the opinions expressed herein, we have:

  -- Reviewed the most current drafts made available to us of the Master
     Agreement and the First Amended and Restated Limited Liability Company
     Operating Agreement with respect to the Company;

  -- Reviewed the summary information provided by McREMI, as property
     manager, the General Partners and the Partnerships for each of the
     properties owned by the Partnerships (the "Properties") including:
     property description, rentable square footage, until mix, year built,
     historical and projected operating statements, rent rolls, tenant
     improvement allowances, expense reimbursements, tax information, capital
     expenditure estimates, deferred maintenance estimates, and estimates of
     costs to remediate environmental conditions;

  -- Conducted limited site inspections of certain of the Properties;

  -- Discussed with management of McREMI and with Stanger the conditions in
     local rental markets and market conditions for sales and acquisitions of
     properties of the type owned by the Partnerships and the historical
     financial statements and budgeted and projected operations of the
     Properties;

  -- Reviewed surveys of competing properties prepared by or on behalf of
     McREMI, the General Partners and the Partnerships, including rental
     rates, vacancies, and tenant improvement allowances;

  -- Reviewed information on acquisition criteria used by real estate
     investors for properties similar to the Properties during 1999;

  -- Reviewed the financial statements of McREMI and its affiliates for the
     years ended December 31, 1997 and 1998 and the three months ended March
     31, 1999;

  -- Interviewed PaineWebber Incorporated regarding the conduct of the bid
     solicitation process relating to the Transaction;

  -- Discussed with Stanger the activities of Stanger since January 1998 with
     respect to the Allocation Analysis and the Stanger Opinion;

  -- Discussed with Houlihan Lokey Howard & Zukin Capital its valuation
     analysis of McREMI; and

  -- Conducted such other studies, analyses, inquiries and investigations as
     we deemed appropriate.

   In rendering this opinion, we have relied, without independent verification,
on the accuracy and completeness in all material respects of all financial and
other information that was furnished or otherwise communicated to us by McREMI,
the General Partners and the Partnerships. We have not performed an independent
appraisal of the assets and liabilities of the Partnerships or the McREMI
Assets. We have not conducted any engineering studies and have relied on the
estimates of the management of McREMI with respect to deferred maintenance and
the estimated cost to remediate environmental conditions for each Property. We
have not reviewed any proxy statement prepared in connection with the
Transaction as one was not available on the date hereof.

   We have relied on the assurance of McREMI, the General Partners and the
Partnerships, that: (i) the Property budgets and discounted cash flow analyses
provided to us were in the judgment of McREMI, the

                                     D-1-3
<PAGE>

General Partners and the Partnerships reasonably prepared on bases consistent
with actual historical experience and reflect the best currently available
estimates and good faith judgments; (ii) any estimates of costs to remediate
environmental conditions are adequately considered in the capital expenditure
estimates provided to us and that no additional environmental conditions are
present at the Properties; (iii) any historical financial data, balance sheet
data, transaction cost estimates and estimates of the deficit restoration
obligation of the General Partners which would be due upon a liquidation are
accurate in all material respects; (iv) no material changes have occurred in
the information reviewed or in the value of the Properties or the McREMI
Assets between the date the information was provided to us and the date of
this letter; and (v) McREMI, the General Partners and the Partnerships are not
aware of any information or facts regarding the Partnerships, the Properties,
the McREMI Assets or the Company that would cause the information supplied to
us to be incomplete or misleading in any material respect.

   We did not determine or negotiate the amount or form of the Aggregate
Consideration. We have not been requested to, and therefore do not: (i) make
any recommendation to McREMI, the General Partners or the Limited Partners
with respect to whether to approve or reject the Transaction; or (ii) express
any opinion as to (a) the impact of the Transaction with respect to McREMI,
the General Partners, or the Limited Partners of any Partnership that does not
participate in the Transaction; (b) the tax consequences of the Transaction
for McREMI, the General Partners or the Limited Partners of any Partnership;
(c) the Company's ability to qualify as a McNeil Partnership or real estate
investment trust, or the consequences of the Company's failure to so qualify;
(d) the potential capital structure of the Company or its impact on the
financial performance of the Membership Interests; (e) the Company's ability
to finance its obligations pursuant to the Master Agreement or the impact of a
failure to obtain financing on the financial performance of the Company or the
Partnerships; (f) whether or not alternative methods of determining or
allocating the Aggregate Consideration to be received by the General Partners,
Limited Partners of the Partnerships or McREMI would have also provided fair
results or results substantially similar to those of the methodology used; (g)
alternatives to the Transaction; or (h) any other terms of the Transaction
other than the Aggregate Consideration and the allocation thereof.
Furthermore, we are not expressing any opinion herein to Robert A. McNeil or
Carole J. McNeil in their capacities as direct or indirect holders of General
or Limited Partner Interests in the Partnerships or McNeil Partners, L.P. or
of capital stock in McREMI. Further, we are not expressing any opinion herein
as to the fairness of any terms of the Transaction other than as described
herein, including without limitation: (i) the fairness of the amounts or
allocations of Transaction costs, or (ii) the prices at which the Membership
Interests in the Company may trade, if at all, following the Transaction, or
the trading value of the Membership Interests compared with the current fair
market value of any assets contributed to the Company in connection with the
Transaction if the Company were to be liquidated in the current real estate
market.

   This letter does not purport to be a complete description of the analyses
performed or the matters considered in rendering our opinion. The analyses and
the summary set forth herein must be considered as a whole, and selecting
portions of such summary or analyses, without considering all factors and
analyses, would create an incomplete view of the processes underlying this
opinion. In rendering this opinion, judgment was applied to a variety of
complex analyses and assumptions. The assumptions made and the judgments
applied in rendering the opinion are not readily susceptible to partial
analysis or summary description. The fact that any specific analysis is
referred to herein is not meant to indicate that such analysis was given
greater weight than any other analysis.

   Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter:

     (i) the Allocation Analysis and Stanger Opinion are based upon the
  application of appropriate methodologies and that the factual bases
  utilized by Stanger in the application of such methodologies have a
  reasonable basis,

     (ii) the conclusions reached in the Allocation Analysis and Stanger
  Opinion have a reasonable basis,

     (iii) the Special Committee is entitled to rely upon such conclusions,
  and

                                     D-1-4
<PAGE>

     (iv) each of the matters set forth in the following clauses (a) through
  (e) is fair from a financial point of view to the holders of each class of
  Limited Partnership Interests in each of the Partnerships: (a) the
  Aggregate Consideration to be paid for the McREMI Assets and the Limited
  Partner Interests and General Partner Interests; (b) the allocation of the
  Aggregate Consideration between Partial McREMI Allocated Value, on the one
  hand, and the Total Allocated Partnership Value, on the other hand; (c) the
  Per Partnership Allocated Value for each Partnership; (d) the methodology
  of allocation of the Net Per Partnership Allocated Value of each
  Partnership among the General Partner Interests, the Second McREMI
  Allocated Value, and each class of Limited Partner Interest of such
  Partnership; and (v) the estimated per unit Excess Cash Balance and Limited
  Partner Consideration Amount with respect to each class of Limited Partner
  Interests for each Partnership determined as of March 31, 1999, based upon
  the balance sheet of each Partnership as of such date adjusted for
  transaction expenses and the allocation thereof, as estimated by the
  General Partners.

   This letter and the opinions set forth herein are being delivered pursuant
to the Agreement and, in accordance with the Agreement, we acknowledge that
further opinions shall be delivered to the Special Committee subsequent to the
date hereof in accordance with the terms of the Agreement.

                                          Very truly yours,

                                         /s/ Eastdil Realty Company L.L.C.

                ARTICLE 7.6. OF THE CALIFORNIA CORPORATIONS CODE

(S) 15679.1. Reorganization; control

   (a) For purposes of this article, "reorganization" refers to either of the
following:

     (1) A merger pursuant to Article 7.5 (commencing with Section 15678.1).

     (2) The acquisition by one limited partnership in exchange in whole or
  part for its partnership interests (or the partnership interests or equity
  securities of a McNeil Partnership or other entity that is in control of
  the acquiring limited partnership) of partnership interests of another
  limited partnership if, immediately after the acquisition, the acquiring
  limited partnership has control of the other limited partnership.

     (3) The acquisition by one limited partnership in exchange in whole or
  in part for its partnership interests (or the partnership interests or
  equity securities of a McNeil Partnership or other entity which is in
  control of the acquiring limited partnership) or for its debts securities
  (or debt securities of a limited partnership or other entity which is in
  control of the acquiring limited partnership) which are not adequately
  secured and which have a maturity date in excess of five years after the
  consummation of the acquisition, or both, of all or substantially all of
  the assets of another limited partnership.

   (b) For purposes of this article, "control" means the possession, direct or
indirect, of the power to direct or cause the direction of the management and
policies of a limited partnership.

(S) 15679.2. Purchase of dissenting partnership interests; fair market value;
dissenting interest; dissenting limited partner

   (a) If the approval of outstanding limited partnership interests is required
for a limited partnership to participate in a reorganization, pursuant to the
limited partnership agreement of the partnership, or otherwise, then each
limited partner of the limited partnership holding those interests may, by
complying with this article, require the limited partnership to purchase for
cash, at its fair market value, the interest owned by the limited partner in
the limited partnership, if the interest is a dissenting interest as defined in
subdivision (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization, excluding
any appreciation or depreciation in consequence of the proposed reorganization.

   (b) As used in this article, "dissenting interest" means the interest of a
limited partner that satisfies all of the following conditions:

     (1) Either:

       (A) The interest was not, immediately prior to the reorganization,
    either (i) listed on any national securities exchange certified by the
    Commissioner of Corporations under subdivision (o) of Section 25100, or
    (ii) listed on the list of OTC margin stocks issued by the Board of
    Governors of the Federal Reserve System, provided that in either such
    instance the limited partnership whose outstanding interests are so
    listed provides, in its notice to limited partners requesting their
    approval of the proposed reorganization, a summary of the provisions of
    this section and Sections 15679.3, 15679.4, 15679.5, and 15679.6.

       (B) Demands for payment are filed with respect to 5 percent or more
    of the outstanding interests of any class of interests described in
    clause (i) or (ii) of subparagraph (A).

     (2) Which was outstanding on the date for the determination of limited
  partners entitled to vote on the reorganization.

     (3) (i) Which was not voted in favor of the reorganization, or (ii) if
  the interest is described in clause (i) or (ii) of subparagraph (A) of
  paragraph (1), was voted against the reorganization; provided, however,

                                      E-1
<PAGE>

  that clause (i) rather than clause (ii) of this paragraph applies in any
  event where the approval for the proposed reorganization is sought by
  written consent rather than at a meeting.

     (4) Which the limited partner has demanded that the limited partnership
  purchase at its fair market value in accordance with Section 15679.3.

     (5) Which the limited partner submits for endorsement, if applicable, in
  accordance with Section 15679.4.

     (c) As used in this article, "dissenting limited partner" means the
  recordholder of a dissenting interest, and includes an assignee of record
  of such an interest.

(S) 15679.3. Notice of approval of reorganization by outstanding interests;
statement of price; written demand for purchase; contents of demand

   (a) If limited partners have a right under Section 15679.2, subject to
compliance with paragraphs (4) and (5) of subdivision (b) thereof, to require
the limited partnership to purchase their limited partnership interests for
cash, such limited partnership shall mail to each such limited partner a notice
of the approval of the reorganization by the requisite vote or consent of the
limited partners, within 10 days after the date of such approval, accompanied
by a copy of this section and Sections 15679.2, 15679.4, 15679.5, and 15679.6,
a statement of the price determined by the limited partnership to represent the
fair market value of its outstanding interests, and a brief description of the
procedure to be followed if the limited partner desires to exercise the limited
partner's rights under such sections. The statement of price constitutes an
offer by the limited partnership to purchase at the price stated any dissenting
interests as defined in subdivision (b) of Section 15679.2, unless they lose
their status as dissenting interests under Section 15679.11.

   (b) Any limited partner who has a right to require the limited partnership
to purchase the limited partner's interest for cash under Section 15679.2,
subject to compliance with paragraphs (4) and (5) of subdivision (b) thereof,
and who desires the limited partnership to purchase such interest, shall make
written demand upon the limited partnership for the purchase of such interest
and the payment to the limited partner in cash of its fair market value. The
demand is not effective for any purpose unless it is received by the limited
partnership or any transfer agent thereof (1) in the case of interests
described in clause (i) or (ii) of subparagraph (A) of paragraph (1) of
subdivision (b) of Section 15679.2, not later than the date of the limited
partners' meeting to vote on the reorganization, or (2) in any other case,
within 30 days after the date on which notice of the approval of the
reorganization by the requisite vote or consent of the limited partners is
mailed by the limited partnership to the limited partners.

   (c) The demand shall state the number or amount of the limited partner's
interest in the limited partnership and shall contain a statement of what such
limited partner claims to be the fair market value of that interest on the day
before the announcement of the proposed reorganization. The statement of fair
market value constitutes an offer by the limited partner to sell the interest
at such price.

(S) 15679.4. Notice of the number or amount of interest demanded to be
purchased; conditions; transfers of interests; new certificates or statements

   Within 30 days after the date on which notice of the approval of the
outstanding interests of the limited partnership is mailed to the limited
partner pursuant to subdivision (a) of Section 15679.3, the limited partner
shall submit to the limited partnership at its principal office or at the
office of any transfer agent thereof, (a) if the interest is evidenced by a
certificate, the limited partner's certificate representing the interest which
the limited partner demands that the limited partnership purchase, to be
stamped or endorsed with a statement that the interest is a dissenting interest
or to be exchanged for certificates of appropriate denominations so stamped or
endorsed, or (b) if the interest is not evidenced by a certificate, written
notice of the number or amount of interest which the limited partner demands
that the limited partnership purchase. Upon subsequent transfers of the
dissenting interest on the books of the limited partnership, the new
certificates or other written statement

                                      E-2
<PAGE>

issued therefor shall bear a like statement, together with the name of the
original holder of the dissenting interest.

(S) 15679.5. Agreements fixing fair market value of dissenting interest;
payment

   (a) If the limited partnership and the dissenting limited partner agree that
such limited partner's interest is a dissenting interest and agree upon the
price to be paid for the dissenting interest, the dissenting limited partner is
entitled to the agreed price with interest thereon at the legal rate on
judgments from the date of consummation of the reorganization. All agreements
fixing the fair market value of any dissenting limited partner's interest as
between the limited partnership and such limited partner shall be in writing
and filed in the records of the limited partnership.

   (b) Subject to the provisions of Section 15679.8, payment of the fair market
value for a dissenting interest shall be made within 30 days after the amount
thereof has been agreed or within 30 days after any statutory or contractual
conditions to the reorganization are satisfied, whichever is later, and in the
case of dissenting interests evidenced by certificates of interest, subject to
surrender of such certificates of interest, unless provided otherwise by
agreement.

(S) 15679.6. Denial of status as dissenting interest; failure to agree upon
fair market value; complaint; filing; joinder of parties; trial of action

   (a) If the limited partnership denies that a limited partnership interest is
a dissenting interest, or the limited partnership and a dissenting limited
partner fail to agree upon the fair market value of a dissenting interest, then
such limited partner or any interested limited partnership, within six months
after the date on which notice of the approval of the reorganization by the
requisite vote or consent of the limited partners was mailed to the limited
partner, but not thereafter, may file a complaint in the superior court of the
proper county praying the court to determine whether the interest is a
dissenting interest, or the fair market value of the dissenting interest, or
both, or may intervene in any action pending on such a complaint.

   (b) Two or more dissenting limited partners may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

   (c) On the trial of the action, the court shall determine the issues. If the
status of the limited partnership interest as a dissenting interest is in
issue, the court shall first determine that issue. If the fair market value of
the dissenting interest is in issue, the court shall determine, or shall
appoint one or more impartial appraisers to determine, the fair market value of
the dissenting interest.

(S) 15679.7. Appraisals; appointment of appraiser; report; submission to court;
confirmation; failure to file report; determination by court; judgment; appeal;
costs

   (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per interest of the outstanding
limited partnership interests of the limited partnership, by class if
necessary. Within the time fixed by the court, the appraisers, or a majority of
them, shall make and file a report in the office of the clerk of the court.
Thereupon, on the motion of any party, the report shall be submitted to the
court and considered on such additional evidence as the court considers
relevant. If the court finds the report reasonable, the court may confirm it.

   (b) If a majority of the appraisers appointed fails to make and file a
report within 30 days from the date of their appointment, or within such
further time as may be allowed by the court, or the report is not confirmed by
the court, the court shall determine the fair market value per interest of the
outstanding limited partnership interests of the limited partnership, by class
if necessary.

   (c) Subject to Section 15679.8, judgment shall be rendered against the
limited partnership for payment of an amount equal to the fair market value, as
determined by the court, of each dissenting interest which any

                                      E-3
<PAGE>

dissenting limited partner who is a party, or has intervened, is entitled to
require the limited partnership to purchase, with interest thereon at the legal
rate on judgments from the date of consummation of the reorganization.

   (d) Any such judgment shall be payable forthwith, provided, however, that
with respect to limited partnership interests evidenced by transferable
certificates of interest, only upon the endorsement and delivery to the limited
partnership of those certificates representing the interests described in the
judgment. Any party may appeal from the judgment.

   (e) The costs of the action, including reasonable compensation for the
appraisers, to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the limited partnership, the limited partnership shall pay the costs
(including, in the discretion of the court, if the value awarded by the court
for the dissenting interest is more than 125 percent of the price offered by
the limited partnership under subdivision (a) of Section 15679.3, attorneys'
fees and fees of expert witnesses).

(S) 15679.8. Extent payment to dissenting partners would require return of
portion thereof by reason of Uniform Fraudulent Transfer Act; dissenting
partners as creditors

   To the extent that the payment to dissenting limited partners of the fair
market value of their dissenting interests would require the dissenting limited
partners to return such payment or a portion thereof by reason of Section 15666
or the Uniform Fraudulent Transfer Act (Chapter 1 (commencing with Section
3439) of Title 2 of Part 2 of Division 4 of the Civil Code), then that payment
or portion thereof shall not be made and the dissenting limited partners shall
become creditors of the limited partnership for the amount not paid, together
with interest thereon at the legal rate on judgments until the date of payment,
but subordinate to all other creditors in any proceeding relating to the
winding up and dissolution of the limited partnership, such debt to be payable
when permissible.

(S) 15679.9. Cash distributions to dissenting partner after reorganization, but
prior to payments by limited partner; credit

   Any cash distributions made by a limited partnership to a dissenting limited
partner after the date of consummation of the reorganization, but prior to any
payment by the limited partnership for such dissenting limited partner's
interest, shall be credited against the total amount to be paid by the limited
partnership for such dissenting interest.

(S) 15679.10  Dissenting limited partners; rights and privileges; withdrawal of
demand for payment

   Except as expressly limited by this article, dissenting limited partners
shall continue to have all the rights and privileges incident to their
interests immediately prior to the reorganization, including limited liability,
until payment by the limited partnership for their dissenting interests. A
dissenting limited partner may not withdraw a demand for payment unless the
limited partnership consents thereto.

(S) 15679.11  Dissenting interests; loss of status

   A dissenting interest loses its status as a dissenting interest and the
holder thereof ceases to be a dissenting limited partner and ceases to be
entitled to require the limited partnership to purchase the interest upon the
happening of any of the following:

     (a) The limited partnership abandons the reorganization. Upon
  abandonment of the reorganization, the limited partnership shall pay, on
  demand, to any dissenting limited partner who has initiated proceeding in
  good faith under this article, all reasonable expenses incurred in such
  proceedings and reasonable attorneys' fees.

                                      E-4
<PAGE>

     (b) The interest is transferred prior to its submission for endorsement
  in accordance with Section 15679.4.

     (c) The dissenting limited partner and the limited partnership do not
  agree upon the status of the interest as a dissenting interest or upon the
  purchase price of the dissenting interest, and neither files a complaint
  nor intervenes in a pending action, as provided in Section 15679.6, within
  six months after the date upon which notice of the approval of the
  reorganization by the requisite vote or consent of limited partners was
  mailed to the limited partner.

     (d) The dissenting limited partner, with the consent of the limited
  partnership, withdraws such limited partner's demand for purchase of the
  dissenting interest.

(S) 15679.12  Litigation; suspension of proceedings pursuant to (S)(S) 15679.6
and 15679.7

   If litigation is instituted to test the sufficient or regularity of the vote
or consent of the limited partners in authorizing a reorganization, any
proceedings under Sections 15679.6 and 15679.7 shall be suspended until final
determination of that litigation.

(S) 15679.13  Application of article

   (a) This article applies to the following:

     (1) A domestic limited partnership formed on or after January 1, 1991.

     (2) A foreign limited partnership if (A) the foreign limited partnership
  was formed on or after January 1, 1991, or filed an application to qualify
  to do business on or after January 1, 1991, and (B) limited partners
  holding more than 50 percent of the voting power held by all limited
  partners of the foreign limited partnership reside in this state.

     (3) A limited partnership if the partnership agreement so provides or if
  all general partners and a majority in interest of the limited partners
  determine that this article shall apply.

   (b) This article does not apply to limited partnership interests governed by
limited partnership agreements whose terms and provisions specifically set
forth the amount to be paid in respect of such interests in the event of a
reorganization of the limited partnership, or to limited partnerships with 35
or fewer limited partners, unless the partnership agreement provides that this
article shall apply or unless all general partners and a majority in interest
of the limited partners agree that this article shall apply.

(S) 15679.14  Right to attack validity of reorganization; action to set aside
or rescind

   (a)  No limited partner of a limited partnership who has a right under this
article to demand payment of cash for the interest owned by such limited
partner in a limited partnership shall have any right at law or in equity to
attack the validity of the reorganization, or to have the reorganization set
aside or rescinded, except in an action to test whether the vote or consent of
limited partners required to authorize or approve the reorganization has been
obtained in accordance with the procedures established therefor by the
partnership agreement of the limited partnership.

   (b) If one of the parties to a reorganization is directly or indirectly
controlled by, or under common control with, another party to the
reorganization, subdivision (a) shall not apply to any limited partner of such
controlled party who has not demanded payment of cash for such limited
partner's interest pursuant to this article; but if such limited partner
institutes any action to attack the validity of the reorganization or to have
the reorganization set aside or rescinded, the limited partner shall not
thereafter have any right to demand payment of cash for such limited partner's
interest pursuant to this article.

   (c) If one of the parties to a reorganization is directly or indirectly
controlled by, or under common control with, another party to the
reorganization, then, in any action to attack the validity of the
reorganization or to

                                      E-5
<PAGE>

have the reorganization set aside or rescinded, (1) a party to a reorganization
which controls another party to a reorganization shall have the burden of
proving that the transaction is just and reasonable as to the limited partners
of the controlled party, and (2) a person who controls two or more parties to a
reorganization shall have the burden of proving that the transaction is just
and reasonable as to the limited partners of any party so controlled.

   (d) Subdivisions (b) and (c) shall not apply if a majority in interest of
the limited partners other than limited partners who are directly or indirectly
controlled by, or under common control with, another party to the
reorganization approve or consent to the reorganization.

   (e) This section shall not prevent a partner of a limited partnership that
is a party to a reorganization from bringing an action against a general
partner of the limited partnership, the limited partnership, or any person
controlling a general partner at law or in equity as to any matters (including,
without limitation, an action for breach of fiduciary obligation or fraud)
other than to attack the validity of the reorganization or to have the
reorganization set aside or rescinded.
