Dear Shareholder:

    The Boards of Trustees of Equity Residential Properties Trust and Lexford
Residential Trust have approved a merger agreement that would result in the
tax-free merger of Lexford into EQR. Lexford shareholders will receive 0.463 of
an EQR common share for each Lexford common share they own. EQR shareholders
will continue to own their existing shares after the merger. EQR common shares
are traded on the New York Stock Exchange under the symbol "EQR."

    At your special meeting, you will be asked to approve the merger of Lexford
into EQR. At the EQR special meeting, EQR shareholders will also be asked to
separately approve an amendment to EQR's Declaration of Trust which will provide
for shareholder approval of mergers or consolidations only when required under
Maryland law.

    The trustees of Lexford, and the trustees of EQR who voted on the merger,
unanimously recommend that all shareholders vote for approval of the merger. In
addition, the Board of Trustees of EQR unanimously recommends that all EQR
shareholders vote for approval of the amendment.

    The merger cannot be completed without the affirmative vote of EQR and
Lexford shareholders owning a majority of the outstanding common shares of EQR
and Lexford, respectively. The approval of the amendment to EQR's Declaration of
Trust requires the affirmative vote of the EQR shareholders owning a majority of
the EQR common shares voted on the matter, provided a quorum is present.

    The dates, times and places of the meetings are:

A: EQR and Lexford believe that the merger will benefit the shareholders of both
    companies. Through the acquisition of Lexford's business, EQR will become a
    leading operator of low density, ranch style apartment homes, a market
    sector EQR has not generally serviced. By receiving EQR shares in the
    merger, the shareholders of Lexford will acquire an equity interest in a
    much larger, more diversified company.

Q:  WHAT ARE THE BOARDS' RECOMMENDATIONS?

A: The trustees of Lexford, and the trustees of EQR who voted on the merger,
    unanimously recommend that the shareholders vote FOR the approval of the
    merger. In addition, the Board of Trustees of EQR unanimously recommends
    that all EQR shareholders vote FOR the approval of the amendment.

Q:  WHAT WILL LEXFORD SHAREHOLDERS RECEIVE IN THE MERGER?

A: Lexford shareholders will receive 0.463 of an EQR common share for each
    Lexford common share they own. Lexford shareholders will receive cash
    instead of any fractional shares of EQR they would otherwise be entitled to.

Q:  CAN THE MARKET VALUE OF THE EQR COMMON SHARES RECEIVED BY LEXFORD
    SHAREHOLDERS CHANGE BETWEEN NOW AND THE TIME THE MERGER IS COMPLETED?

A: Yes. Because the exchange ratio of 0.463 is fixed, the market value of the
    EQR common shares received by the shareholders of Lexford may change between
    now and the time the merger is completed, based on any change in market
    price of the EQR common shares between now and the completion of the merger.

Q:  DO I HAVE APPRAISAL RIGHTS?

A: No. Neither EQR nor Lexford shareholders have appraisal rights in connection
    with the merger. For more details, see page 32 of this joint proxy
    statement/prospectus.

Q:  WHAT ARE THE FEDERAL TAX CONSEQUENCES OF THE MERGER TO THE SHAREHOLDERS OF
    LEXFORD?

A: The receipt of EQR common shares by the Lexford shareholders will be tax-free
    for federal income tax purposes. However, cash received for a fractional
    shares of EQR will be taxable to Lexford shareholders. The merger will have
    no tax consequences for EQR shareholders. PLEASE BE AWARE THAT TAX MATTERS
    ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL
    DEPEND ON THE FACTS OF YOUR OWN SITUATION. FOR MORE DETAILS, SEE PAGE 37 OF
    THIS JOINT PROXY STATEMENT/PROSPECTUS.

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: We hope to complete the merger on the same date as the EQR and Lexford
    special meetings, assuming the shareholders of EQR and Lexford approve the
    merger.

Q:  WHY DOES EQR WANT TO AMEND ITS DECLARATION OF TRUST?

A: In 1997, Maryland law was changed to allow mergers of real estate investment
    trusts, or REITs, to be approved by a Maryland REIT surviving a merger only
    by a majority of the board of trustees without a vote of the shareholders so
    long as (1) the merger does not reclassify or change the REIT's outstanding
    shares or otherwise amend its declaration of trust and (2) the number of
    shares to be issued or delivered in the merger is not more than 20% of the
    number of its shares of the same class or

                                       1
<PAGE>
    series outstanding immediately before the merger becomes effective.

    These new requirements regarding shareholder approval of mergers are similar
    to the requirements of the New York Stock Exchange, or NYSE, where the EQR
    common shares are listed. The proposed amendment would provide for
    shareholder approval of mergers or consolidations only when required under
    Maryland law, as amended. The amendment will provide EQR with added
    flexibility to react to acquisition opportunities. The text of the amendment
    is included in Appendix B to this joint proxy statement/prospectus.

Q:  WHAT VOTE IS REQUIRED TO APPROVE THE MERGER AND AMENDMENT?

A: The merger must be approved by the affirmative vote of EQR and Lexford
    shareholders owning a majority of the outstanding common shares of EQR and
    Lexford, respectively. The amendment must be approved by the affirmative
    vote of EQR shareholders owning a majority of the shares voted on the matter
    at the EQR special meeting, so long as a quorum is present.

Q:  HOW DO I VOTE?

A: Your vote is important. Shareholders can vote in person at their special
    meeting or by proxy. If you are a registered holder (that is, you hold your
    shares in your own name and not through a broker or other nominee), there
    are three ways to vote by proxy:

    - BY TELEPHONE: You can vote by touch-tone telephone by using the toll-free
      number [1-877-PRX-VOTE (1-877-779-8683)] and following the instructions on
      your proxy card;

    - BY INTERNET: You can vote by Internet by going to the website at
      [http://www.eproxyvote.com/eqr] if you are an EQR shareholder or
      [http://www.eproxyvote.com/lft] if you are a Lexford shareholder and
      following the instructions provided; or

    - BY MAIL: You can vote by mail by signing, dating and mailing the enclosed
      proxy card in the envelope provided.

    If you hold your shares in "street name" with a broker, your broker will
    vote your shares only if you provide your broker with instructions on how to
    vote. You should follow the directions provided by your broker regarding how
    to instruct your broker to vote your shares. Without instructions, your
    shares will not be voted, which will have the same effect as voting against
    the merger.

Q:  CAN I REVOKE OR CHANGE MY PROXY?

A: Yes, you may change or revoke your proxy at any time before the meeting. To
    do so, you must:

    - advise the Secretary of your company in writing before your shares are
      voted by the proxy holders at the meeting;

    - deliver later proxy instructions; or

    - attend your meeting and vote your shares in person.

    The powers of your proxy holder will be suspended if you attend your meeting
    in person and so request, but attendance at the meeting will not by itself
    revoke a previously granted proxy.

Q:  AS A LEXFORD SHAREHOLDER, SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. After the merger is completed, we will send you written instructions
    regarding the surrender of your certificates.

PARTIES TO THE MERGER

EQUITY RESIDENTIAL PROPERTIES TRUST
Two North Riverside Plaza
Chicago, Illinois 60606
(312) 474-1300

    EQR is a real estate investment trust and one of the largest publicly traded
real estate companies. EQR was organized in March 1993 and commenced operations
as a publicly traded company on August 18, 1993 upon the completion of its
initial public offering. EQR was formed to continue the multifamily property
business objectives and acquisition strategies of affiliated entities controlled
by Mr. Samuel Zell, Chairman of the Board of Trustees of EQR. These entities had
been engaged in the acquisition, ownership and operation of multifamily
properties since 1969. EQR's senior executive officers average over 25 years of
experience in the multifamily property business.

    EQR is the largest publicly traded owner of multifamily properties, based on
the number of apartment units wholly-owned and total revenues earned. As of June
30, 1999, EQR owned or had interests in a portfolio of 686 multifamily
properties containing 193,615 apartment units and managed 6,346 additional units
owned by affiliated and non-affiliated entities. As of June 30, 1999, the
properties EQR owned or had interests in had an average occupancy rate of
approximately 95%. These properties are located in 34 states.

    All of EQR's interests in its properties are held directly or indirectly by,
and substantially all of its operations are conducted through, ERP Operating
Limited Partnership, an Illinois limited partnership. EQR controls ERP Operating
Limited Partnership as its sole general partner and, as of June 30, 1999, owned
approximately 91% of ERP Operating Limited Partnership's outstanding partnership
interests, excluding preference units. Partnership interests in ERP Operating
Limited Partnership may be exchanged for either common shares of EQR on a
one-for-one basis or, at EQR's option, the cash equivalent of the applicable
number of common shares. In addition to its corporate headquarters, EQR has 30
management offices in 19 states.

LEXFORD RESIDENTIAL TRUST
6954 Americana Parkway
Columbus, Ohio 43068
(614) 759-1566

    Lexford is a real estate investment trust that owns, manages and invests in
direct or indirect ownership interests in multifamily apartment communities.
Lexford is a leading provider of housing to "value conscious" renters, which
Lexford defines as renters who prefer clean, attractive housing without
unnecessary amenities at rental rates below the median rent in the local housing
market.

    Lexford became publicly held in 1992 as a result of the distribution of
common stock to creditors pursuant to the Chapter 11 bankruptcy reorganization
of the former Cardinal Industries, Inc. Cardinal Industries, Inc. changed its
name to Cardinal Realty Services, Inc. in connection with the bankruptcy
reorganization. In October 1997, the shareholders of Cardinal Realty Services,
Inc. approved a change of name to Lexford, Inc., which created and merged into
Lexford in March 1998 for the purpose of Lexford, Inc.'s reorganization as a
Maryland REIT. The common shares of Lexford were listed and admitted for trading
on the NYSE on March 19, 1998.

                                       4
<PAGE>
    As of June 30, 1999, Lexford's portfolio of 402 properties consisted of
36,609 units in 16 states.

THE MERGER (SEE PAGE 17)

    Lexford will be merged into EQR. Upon completion of the merger, each
outstanding Lexford common share will be converted into 0.463 (the exchange
ratio) of an EQR common share.

RECOMMENDATIONS OF THE BOARDS OF TRUSTEES (SEE PAGE 21)

    EQR

    The EQR Board of Trustees believes that the merger, including the
consideration to be paid by EQR, is fair and in the best interests of EQR and
its shareholders. THE EQR TRUSTEES WHO VOTED ON THE MERGER UNANIMOUSLY APPROVED
THE MERGER AND UNANIMOUSLY RECOMMEND THAT THE EQR COMMON SHAREHOLDERS VOTE FOR
THE MERGER. In making its decision, the EQR Board of Trustees considered the
positive and negative factors which could arise from the merger.

    LEXFORD

    The Lexford Board of Trustees believes that the merger is fair to, and in
the best interests of, Lexford and its shareholders. BY UNANIMOUS VOTE, THE
LEXFORD BOARD OF TRUSTEES APPROVED THE MERGER AND THE TRANSACTIONS CONTEMPLATED
THEREBY, AND UNANIMOUSLY RECOMMENDS THAT THE LEXFORD COMMON SHAREHOLDERS VOTE
FOR THE MERGER. The Lexford Board of Trustees reached its decision after careful
consideration of a wide variety of factors, including potentially positive and
negative factors, as well as the written opinion of Morgan Stanley & Co.
Incorporated.

OPINION OF FINANCIAL ADVISOR (SEE PAGE 25)

    EQR

    The Board of Trustees of EQR did not seek an opinion of an independent
financial advisor as to the fairness of the merger from a financial point of
view to the shareholders of EQR.

    LEXFORD

    At the meeting of the Lexford Board of Trustees on June 30, 1999, Morgan
Stanley delivered its oral opinion to the Lexford Board of Trustees, and
subsequently on June 30, 1999, Morgan Stanley delivered its written opinion,
that, as of that date and based upon and subject to the matters described in the
opinion, the consideration to be received by the holders of Lexford common
shares pursuant to the merger agreement was fair from a financial point of view
to the Lexford shareholders. Morgan Stanley's written opinion is attached as
Appendix C to this joint proxy statement/prospectus. Lexford common shareholders
are urged to read the written opinion of Morgan Stanley carefully and in its
entirety.

INTERESTS OF LEXFORD MANAGEMENT AND TRUSTEES IN THE MERGER (SEE PAGE 47)

    In considering whether to approve the merger, shareholders should be aware
that some members of the management of Lexford and the Lexford trustees have
interests in the merger that are in addition to the interests of Lexford
shareholders generally. These interests include severance and transition
payments, acceleration of vesting of restricted Lexford common shares,
acceleration of vesting of stock options and tax recognition payments. The
Lexford Board of Trustees considered these interests and deliberated upon any
resulting conflicts of interest in connection with its unanimous approval of the
merger and the benefits of the merger to the shareholders of Lexford.

THE MERGER AGREEMENT (SEE PAGE 17)

    The merger agreement is the legal document which governs the merger. The
merger agreement provides that, upon satisfaction or waiver of the conditions
contained in the merger agreement, Lexford will be merged into EQR. We encourage
you to read the merger agreement which is attached as Appendix A to this joint
proxy statement/prospectus.

CONDITIONS TO THE MERGER (SEE PAGE 31)

    The obligations of EQR and Lexford to complete the merger are subject to the

                                       5
<PAGE>
satisfaction or waiver of the conditions described in the merger agreement.
These conditions include:

    - obtaining the requisite approval of the shareholders of EQR and Lexford;

    - the absence of any material adverse change in the financial condition,
      business or operations of Lexford or EQR;

    - the receipt of specified legal opinions; and

    - the receipt of all material consents, authorizations, orders and approvals
      of governmental agencies and third parties.

    EQR and Lexford each have the right to waive any conditions to their
respective obligations to complete the merger.

TERMINATION (SEE PAGE 33)

    The merger agreement provides that it may be terminated in a number of
circumstances at any time prior to the completion of the merger, whether before
or after the approval of the merger by the shareholders of EQR and shareholders
of Lexford.

TERMINATION FEES (SEE PAGE 34)

    Depending on the reason for the merger agreement's termination, Lexford may
be required to pay EQR a break-up fee of $8 million or an expense fee of up to
$4 million or both. Alternatively, EQR may be required to pay Lexford an expense
fee of up to $4 million.

ACCOUNTING TREATMENT (SEE PAGE 37)

    The merger will be treated as a purchase for accounting purposes.

NO SOLICITATION OF OTHER TRANSACTIONS (SEE PAGE 35)

    Lexford has agreed that it will not initiate, solicit or encourage any
inquiries or offers to acquire all or any significant portion of the assets or
equity securities of Lexford or any of its subsidiaries, other than the merger.

    Notwithstanding the above restrictions, the merger agreement does not
prohibit Lexford from entering into discussions with respect to an unsolicited
proposal if the Lexford Board of Trustees determines that the discussions are
required by its legal duties to its shareholders.

CONVERSION OF SHARES (SEE PAGE 35)

    Each common share of Lexford outstanding immediately before the completion
of the merger will be converted into 0.463 of an EQR common share. When the
merger becomes effective, all Lexford common shares will no longer be
outstanding and will automatically be canceled and retired. Each holder of a
certificate evidencing Lexford common shares will cease to have any rights with
respect to the Lexford common shares, except the right to receive (1) common
shares of EQR, (2) cash instead of any fractional common shares of EQR and (3)
any distributions declared with respect to the Lexford common shares with a
record date before the completion of the merger.

THE AMENDMENT (SEE PAGE 50)

    The EQR common shareholders are being requested to separately vote to
approve an amendment to EQR's Declaration of Trust which will be adopted as part
of the merger. The amendment will provide for shareholder approval of mergers
and consolidations only when required under Maryland law.

    Approval of the amendment requires the affirmative vote of the EQR
shareholders owning a majority of the EQR common shares voted on the matter at
the EQR special meeting, provided a quorum is present.

COMPARATIVE PER SHARE DATA

    The following information presents selected comparative unaudited per share
information for EQR and Lexford on a historical basis and on a pro forma
combined basis assuming the merger had been effective throughout the periods
presented. Lexford pro forma equivalent per share amounts are presented with
respect to pro forma information. These per share amounts allow comparison of
historical information with respect to the value of one Lexford common share to
the corresponding information with respect to the projected value of one EQR
common share as a result of the merger by multiplying the pro forma amounts by
the exchange ratio of 0.463. All amounts are presented assuming dilution giving
effect to the Statement of Financial Accounting Standard No. 128 "Earnings Per
Share."

(A) The pro forma combined Net Income (Loss) Per Common Share and Shareholders'
    Equity Per Common Share data for EQR has been prepared assuming that in the
    merger each Lexford common share is converted into 0.463 of an EQR common
    share resulting in total weighted average outstanding EQR common shares
    (assuming dilution) of 136.2 million and 137.2 million for the year ended
    December 31, 1998 and for the three months ended March 31, 1999,
    respectively. For the Shareholder's Equity Per Common Share data, total
    outstanding common shares were 123.7 million at March 31, 1999.

(B) The pro forma combined Net Income (Loss) Per Common Share and Shareholders'
    Equity Per Common Share data for EQR also gives effect to other acquisition
    transactions, property purchases, borrowings and securities offerings
    occurring during the relevant periods, as further described in the unaudited
    pro forma combined financial statements and notes included in this joint
    proxy statement/prospectus.

(C) The Lexford pro forma equivalent is determined by multiplying the exchange
    ratio (0.463) by the EQR pro forma combined per share amounts so that the
    per share amounts are equated to the comparative values for each Lexford
    common share.

    The merger agreement provides that until the merger occurs or until the
merger agreement is terminated, any distribution on Lexford common shares for
each quarterly distribution after the second quarter of 1999 shall not exceed an
amount equal to the distribution on a common share of EQR for such quarter
multiplied by 0.463 (the exchange ratio). In addition, the merger agreement
provides that the record and payment dates for any Lexford distributions must be
the same as the record and payment dates for the distribution on EQR common
shares for the same period.

    The table below shows the closing price for EQR and Lexford common shares on
June 30, 1999, the last full trading day prior to the public announcement of the

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

    Certain statements in the Summary and under captions "Risk Factors," "The
Merger--Advantages and Disadvantages of the Merger; Recommendation of the EQR
Board of Trustees" "--Advantages and Disadvantages of the Merger; Recommendation
of the Lexford Board of Trustees," "--Opinion of the Financial Advisor for
Lexford" and elsewhere in this joint proxy statement/prospectus are intended to
constitute "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. You may find many of these statements
by looking for words such as "believes," "expects," "anticipates," "estimates,"
or similar expressions in this joint proxy statement/prospectus or in documents
incorporated herein. These forward-looking statements involve known and unknown
risks, uncertainties and other factors which may cause the actual results,
performance or achievements of EQR, Lexford, the combined company or the
industry to be materially different from any future results, performance or
achievements expressed or implied by such forward-looking statements. Such
factors include, among others:

    - general and local economic and business conditions, which will, among
      other things, affect demand for multifamily properties, availability and
      creditworthiness of prospective tenants;

    - the availability of financing;

    - adverse changes in the real estate markets including, among other things,
      competition with other companies, risks of real estate development and
      acquisitions;

    - governmental actions and initiatives;

    - environmental and safety requirements;

    - ability to achieve anticipated cost savings and operating efficiencies
      from the merger; and

    - other changes and factors referenced in this joint proxy
      statement/prospectus and the documents incorporated into this joint proxy
      statement/prospectus by reference.

Because forward-looking statements are subject to risks and uncertainties,
actual results may differ materially from those expressed or implied by
forward-looking statements. You should not place undue reliance on these
statements, which speak only as of the date of this joint proxy
statement/prospectus or, in the case of a document incorporated by reference,
the date of such document.

<PAGE>
                                  RISK FACTORS

    In considering whether to approve the merger, you should consider the risks
described in this section and in the documents we incorporate by reference into
this joint proxy statement/prospectus.

LEXFORD SHAREHOLDERS WILL REALIZE A DECREASE IN DISTRIBUTIONS PER SHARE

    The distribution declared on Lexford common shares for each of the first two
quarters of 1999 was $0.43250 and the distribution declared on 0.463 of an EQR
common share (the amount each common share of Lexford will be converted into
pursuant to the merger) for each of the first two quarters of 1999 was $0.32873.

LEXFORD TRUSTEES AND MANAGEMENT HAVE INTERESTS IN THE MERGER WHICH DIFFER FROM
THE INTERESTS OF LEXFORD SHAREHOLDERS GENERALLY

    Shareholders should be aware that some Lexford trustees, officers and
members of management have certain interests in connection with the merger that
are in addition to the interests of Lexford shareholders generally. Such
interests include severance and transition payments, acceleration of vesting of
restricted Lexford shares, acceleration of vesting of stock options and tax
recognition payments. Therefore, a conflict between the interests of these
individuals and the interests of the Lexford shareholders could exist. These
interests are described in the section "Interests of Lexford Management and
Trustees in the Merger."

POTENTIAL CHANGE IN RELATIVE SHARE PRICES OF LEXFORD AND EQR COULD AFFECT THE
VALUE OF THE CONSIDERATION RECEIVED BY LEXFORD SHAREHOLDERS

    In considering whether to approve the merger, Lexford shareholders and EQR
shareholders should consider the fact that the exchange ratio for the merger is
fixed at 0.463 of an EQR common share for each Lexford common share. A fixed
exchange ratio means that Lexford shareholders will receive the same number of
EQR common shares regardless of the price at which EQR common shares are trading
at the time of the merger. Therefore, an increase or decrease in the trading
price of EQR common shares would result in a corresponding increase or decrease
in the value of consideration received by Lexford shareholders. Neither Lexford
nor EQR has the right to terminate the merger agreement because of any change in
the prevailing market price of EQR or Lexford common shares.

PAYMENTS OF FEES AND EXPENSES BY LEXFORD IF THE MERGER FAILS TO OCCUR COULD
ADVERSELY AFFECT LEXFORD'S ABILITY TO ENGAGE IN OTHER TRANSACTIONS

    The merger agreement provides for a break-up fee of $8 million payable by
Lexford plus an expense fee of up to $4 million if the merger agreement is
terminated by either EQR or Lexford under specified circumstances and if, at the
time of termination, Lexford has received another acquisition proposal and,
within one year after the termination Lexford enters into an agreement regarding
the acquisition of Lexford or the sale of substantially all of its assets, which
acquisition or sale is later completed. In addition, if the merger agreement is
terminated for specified reasons, EQR or Lexford will be required to pay the
other party an expense fee of up to $4 million. See "The Merger-- Termination
Fee and Expenses."

    The obligation to pay the break-up fee or the expense fee or both may
adversely affect the ability of Lexford to engage in another transaction in the
event the merger is not consummated.

SHAREHOLDERS OF EQR AND LEXFORD HAVE NO APPRAISAL RIGHTS UNDER MARYLAND LAW

    Neither EQR shareholders nor Lexford shareholders are entitled to appraisal
rights in connection with the merger under Maryland law. See "The Merger--No
Appraisal Rights."

                                       14
<PAGE>
LEXFORD PROPERTIES REPRESENT A NEW MARKET SECTOR FOR EQR

    Lexford is a leading operator of low density, ranch style apartment homes.
EQR has not generally served this sector of the rental housing market and has
limited experience operating this property type. Consequently, there can be no
assurance that EQR will be successful in operating Lexford's properties.

THE MERGER WILL INCREASE EQR'S DEBT

    By assuming Lexford's debt pursuant to the merger, EQR's total debt will
increase by approximately $555 million or 12% on a pro forma basis as of March
31, 1999 and EQR's debt to total market capitalization ratio will increase from
40% to 42% as of March 31, 1999. This increase could adversely affect EQR's
ability to obtain additional debt financing in the future for working capital,
capital expenditures, acquisitions, development or other general purposes,
making EQR more vulnerable to a downturn in business or the economy generally.

LEXFORD SHAREHOLDERS WILL HAVE REDUCED VOTING POWER AS A GROUP AFTER THE MERGER

    Upon completion of the merger, Lexford common shareholders will own
approximately 3.6% of the outstanding EQR common shares and will not have
separate approval rights with respect to any actions or decisions of EQR.

EQR COULD BE DISQUALIFIED AS A REIT OR HAVE TO PAY TAXES IF LEXFORD DOES NOT
QUALIFY AS A REIT

    If Lexford has failed to qualify as a REIT since its taxable year beginning
January 1, 1998, then it might have undistributed "C corporation earnings and
profits" at the time of the merger. If that is the case and EQR does not
distribute these earnings and profits prior to the end of the year in which the
merger takes place, EQR might not qualify as a REIT. EQR and Lexford believe
that Lexford qualifies as a REIT. EQR and Lexford further believe that even if
Lexford did have "C corporation earnings and profits" at the time of the merger,
such "C corporation earnings and profits" would be distributed prior to the end
of the year in which the merger took place. If Lexford has failed to qualify as
a REIT, an additional concern would be that it will recognize taxable gain at
the time of the merger. EQR would be liable for the tax on such gain. In this
event, EQR would have to pay corporate income tax on any gain existing at the
time of the merger on assets acquired in the merger if the assets are sold
within ten years of the merger. Finally, EQR could be precluded from electing
REIT status for up to four years after the year in which Lexford failed to
qualify for REIT status.

                          THE MEETINGS OF SHAREHOLDERS

EQR

    The special meeting of EQR shareholders has been called by the President of
EQR for the purpose of approving the merger and the amendment. The EQR special
meeting will be held on             , 1999, at       .m., local time, at One
North Franklin, Chicago, Illinois. Only holders of record of EQR common shares
at the close of business on             , 1999 will be entitled to vote at the
EQR special meeting. EQR had outstanding 122,243,928 EQR common shares as of the
close of business on July 19, 1999, of which 6,726,287 (or approximately 5.5% of
the outstanding EQR common shares) (excluding 2,052,928 shares where beneficial
ownership is disclaimed) were owned beneficially by the officers and trustees of
EQR, who have indicated their intention to vote such shares in favor of the
merger and the amendment. No EQR shares other than EQR common shares are
entitled to vote on the merger or the amendment. You are entitled to one vote
per EQR common share you own on the merger and the amendment. If you sign and
return the accompanying proxy form, your EQR common shares will be voted in
accordance with your direction on the proxy form, or in the absence of a
direction, your shares will be voted for the merger and the amendment. In
addition, if you are a shareholder of record, you can vote by using the
toll-free telephone number [1-877-PRX-VOTE

                                       15
<PAGE>
(1-877-779-8683)] or the Internet by going to the website at
[http://www.eproxyvote.com/eqr.] Before the special meeting, you may change your
vote or revoke your proxy at any time by:

    - giving written notice to Bruce C. Strohm, Executive Vice President,
      General Counsel and Secretary of EQR, Two North Riverside Plaza, Suite
      400, Chicago, Illinois 60606;

    - executing and delivering a later-dated proxy; or

    - attending the special meeting of EQR shareholders and voting in person.

    The expenses of the solicitation of EQR common shareholders will be paid by
EQR. In addition to the use of the mail, trustees, officers, or regular
employees of EQR may solicit proxies in person, by telecopy or by telephone. EQR
will arrange with brokerage firms and other custodians, nominees and fiduciaries
to forward solicitation materials to the beneficial owners of EQR common shares.
EQR will also reimburse these brokerage firms, custodians, nominees and
fiduciaries for reasonable out-of-pocket expenses incurred by them in connection
with forwarding the solicitation materials. EQR has retained MacKenzie Partners
to assist in the solicitation of proxies. Their fee is estimated to be $6,000,
plus reimbursement for out-of-pocket costs and expenses.

    The presence, in person or by proxy, of the holders of a majority of the
outstanding EQR common shares is necessary to constitute a quorum under the EQR
Bylaws. Votes cast by proxy or in person at the meeting will be tabulated by
election inspectors appointed for the meeting who will also determine whether or
not a quorum is present. Under Maryland law, the EQR Declaration of Trust and
the EQR Bylaws, the affirmative vote by the holders of a majority of the
outstanding EQR common shares is required to approve the merger, and the
affirmative vote of a majority of the EQR common shares voted on the matter at
the special EQR meeting, provided a quorum is present, is required to approve
the amendment.

    You may separately mark the accompanying EQR proxy to vote your shares FOR

    THE LEXFORD BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT THE LEXFORD COMMON
SHAREHOLDERS VOTE FOR THE MERGER.

    The Lexford Bylaws provide that no business may be transacted at the special
meeting except the business referred to in the accompanying notice of meeting.
If, however, any other matters are properly presented at the Lexford special
meeting, it is intended that the persons named in the enclosed form of proxy
will have discretion to vote on those matters in accordance with their judgment.

                                   THE MERGER

    The following is a brief summary of the material terms of the merger and the
merger agreement. To understand the merger fully, and for a more complete
description of the legal terms of the merger, you should carefully read this
entire document, including the merger agreement, which is attached as Appendix A
and is incorporated herein by reference. This summary is qualified in its
entirety by reference to the full text of the merger agreement.

TERMS OF THE MERGER

    Lexford will be merged into EQR upon satisfaction or waiver of the
conditions set forth in the merger agreement. Upon the completion of the merger,
each outstanding Lexford common share will be converted into 0.463 of an EQR
common share. No fractional shares of EQR will be issued in

                                       17
<PAGE>
connection with the merger. Lexford common shareholders will instead receive a
cash payment equal to (1) the average closing price of an EQR common share on
the NYSE for the five trading days immediately preceding the completion of the
merger, multiplied by (2) the fraction of an EQR common share which the Lexford
shareholder would otherwise be entitled to receive under the merger agreement.

BACKGROUND OF THE MERGER

    In conjunction with its determination in late 1997 to make a REIT election
for 1998 federal income tax purposes, Lexford announced its intention to raise
capital in order to reduce its total indebtedness and bring its debt to total
market capitalization ratio more in line with those of other publicly traded
REITs. Lexford's initial strategy to fulfill this objective was to conduct a
public offering of its common shares. However, in late May 1998, during the week
preceding the declaration of the effectiveness of its registration statement for
that public offering, market prices for Lexford common shares declined from $23
to $19 per share. Based upon this rapid decline in Lexford's common share price,
coupled with an overall weakening of demand in the equity capital markets,
especially in the REIT sector, Lexford terminated its plans for that public
offering.

    Subsequent to May 1998, Lexford's management and Board of Trustees, along
with its financial advisor Morgan Stanley, reviewed strategic alternatives
available to accomplish its stated objective of reducing Lexford's debt level.
Lexford's Board of Trustees received Morgan Stanley's analysis of a number of
identifiable strategic alternatives, including:

    - continuing to operate on a stand-alone basis;

    - limited private or public offerings of preferred shares or additional
      common shares;

    - a recapitalization transaction involving the creation of a joint venture
      with or a similar capital investment from a private equity source;

    - sales of selected multifamily properties with net proceeds available being
      used to reduce Lexford's remaining indebtedness;

    - conversion to a C corporation for federal income tax purposes; and

    - a merger or sale of Lexford as a going concern.

    At its January 6, 1999 meeting, the Lexford Board of Trustees, after
considering Morgan Stanley's analysis, decided that the sale or merger
alternative presented the most effective strategic alternative available to
Lexford and its shareholders. The closing price of Lexford common shares on
January 6, 1999 was $17 15/16. The Lexford Board of Trustees authorized Morgan
Stanley and Brown, Gibbons, Lang & Company, L.P., an investment banking firm and
an affiliate of Glenn C. Pollack, a trustee of Lexford, to solicit interest from
strategic merger partners or buyers. Over the next several months, Morgan
Stanley and Brown Gibbons Lang contacted approximately 30 potential strategic
merger partners or buyers, and secured confidentiality agreements and provided
proprietary information to the 17 potential strategic merger partners or buyers
that expressed interest in a possible transaction. At the Lexford Board of
Trustees meetings held on February 8, 1999 and April 28, 1999, Morgan Stanley
reported the progress of this process to the Lexford Board of Trustees, and the
Lexford Board of Trustees had the opportunity to ask questions of Morgan Stanley
concerning this process.

    At a Commercial Property News award dinner held in New York on March 23,
1999, Douglas Crocker II, President and Chief Executive Officer of EQR, and
David J. Neithercut, Executive Vice President and Chief Financial Officer of
EQR, met with representatives of Morgan Stanley to discuss the general status of
the multifamily industry and various financing and strategic topics. The Morgan
Stanley representatives also disclosed their role as financial advisor to
Lexford and suggested EQR consider the acquisition of Lexford.

                                       18
<PAGE>
    As a result of further discussions between Messrs. Crocker and Neithercut,
Bruce C. Strohm, Executive Vice President and General Counsel of EQR, and the
Morgan Stanley representatives, EQR and Lexford entered into a confidentiality
agreement on March 26, 1999. Throughout April, Messrs. Crocker and Neithercut
continued discussions with the Morgan Stanley representatives regarding the
strategic rationale for and potential strategic merits of a combination between
EQR and Lexford, and whether a combination was in the best interests of both
companies and their shareholders. As a result of these discussions, EQR
expressed a general interest in exploring the possibility of a combination.

    At Lexford's April 28, 1999 Board of Trustees meeting, Morgan Stanley
reported that it had received expressions of interest from three parties, one of
which was EQR.

    On May 13, 1999, EQR submitted to Morgan Stanley an initial non-binding
indication of interest regarding a possible merger of EQR and Lexford. A week
later, Gerald A. Spector, Executive Vice President and Chief Operating Officer
of EQR, met with Leslie Fox, Executive Vice President and Chief Operating
Officer of Lexford, in Arizona. They discussed key operational and employment
issues, including the continuing role of the Lexford employees following a
merger of EQR and Lexford. After further discussions between executives of EQR
and Lexford regarding valuation and financial matters and continuing due
diligence, EQR submitted to Morgan Stanley a revised non-binding indication of
interest on May 26, 1999.

    At its May 28, 1999 meeting, the Lexford Board of Trustees reviewed revised
indications of interest from the three interested parties, including EQR. The
Lexford Board of Trustees, after considering the advice of each of Morgan
Stanley and Brown Gibbons Lang, concluded that the EQR indication of interest
presented the most attractive proposal to Lexford and its shareholders. At its
May 28, 1999 meeting, the Lexford Board of Trustees authorized Lexford to enter
into an exclusive negotiation agreement with EQR, since, among other reasons,
the EQR indication of interest, based on the then current market price of EQR
common shares, was at a price substantially in excess of $17 11/16, the then
current market price of Lexford common shares. The Lexford Board of Trustees, in
authorizing the exclusive negotiation agreement, also considered the due
diligence conducted by EQR through May 28, 1999, EQR's reputation for
successfully and efficiently completing acquisition transactions, EQR's strong
capital position and the fact that EQR would not need to raise capital to
complete the merger contemplated by its indication of interest.

    On June 3, 1999, Messrs. Spector and Strohm and other EQR executives,
including Alan George, Executive Vice President--Acquisitions & Dispositions,
met with John B. Bartling, President and Chief Executive Officer of Lexford, Ms.
Fox, Mark D. Thompson, Executive Vice President and Chief Financial Officer of
Lexford, Bradley A. Van Auken, Senior Vice President and General Counsel of
Lexford, and other Lexford executives, together with a representative from
Morgan Stanley, at Lexford's executive offices in Columbus, Ohio. At the
meeting, the parties discussed Lexford's organizational structure, the estimated
future financial results of Lexford and other financial, legal, operational and
accounting matters. The parties entered into an exclusive negotiation agreement
dated as of June 3, 1999. Reciprocal due diligence commenced, including
financial and property due diligence.

    On June 14, 1999, the managements of EQR and Lexford and their respective
counsel met at the Chicago offices of Rudnick & Wolfe, counsel to EQR, where the
parties negotiated and discussed unresolved business and legal matters regarding
the proposed transaction. From June 15, 1999 through June 23, 1999, the members
of management of EQR, attorneys from EQR's legal staff and the management of
Lexford, including Mr. Van Auken, as well as representatives of Rudnick & Wolfe,
counsel to EQR, and representatives of Willkie Farr & Gallagher, counsel to
Lexford, had a number of discussions by teleconference regarding the possible
structure of the merger transaction, tax matters,

                                       19
<PAGE>
various employment issues, and other transaction terms. The due diligence
process continued and various other business and legal matters were also
discussed.

    At a meeting of EQR's Board of Trustees on June 23, 1999, Mr. Crocker
discussed the background and events leading up to the proposed merger and the
reasons that a combination with Lexford would be beneficial. Mr. Crocker also
advised the EQR Trustees of the status of negotiations, including the substance
of the discussions with Lexford to date. Members of management of EQR also
reported on the nature and results of their due diligence review of the
properties, business, and financial condition of Lexford. From June 24, 1999
through June 29, 1999, members of management of each of EQR and Lexford and
their respective legal advisors spoke by telephone several times regarding the
outstanding items.

    On June 23, 1999, a special meeting of the Lexford Board of Trustees was
held. At the meeting, members of senior management and Lexford's legal and
financial advisors reviewed with the Lexford Board of Trustees the background
and status of the proposed transaction, the status of due diligence and the
terms of the current draft of the merger agreement, which the Board had received
and had the opportunity to review prior to the meeting. Representatives of
Morgan Stanley made a presentation as to the status of their financial analysis
of EQR and the proposed transaction. Members of the Lexford Board of Trustees
asked questions of management and its advisors and a discussion of the
respective presentations followed. No action was taken by the Lexford Board of
Trustees at such time.

    On June 29, 1999, a special meeting of the EQR Board of Trustees was held.
At that meeting, the EQR Trustees were informed of the status of the ongoing
negotiations with Lexford. The EQR Trustees reviewed the proposed terms of the
merger agreement, including the exchange ratio, closing conditions, termination
rights and liquidated damages and expense reimbursement provisions. Mr.
Neithercut and other members of EQR management made a detailed presentation
regarding the proposed merger with Lexford, which included:

    - the fairness from a financial point of view to EQR of the consideration to
      be paid by EQR in the proposed merger;

    - a summary of the financial terms of the proposed merger;

    - a valuation analysis; and

    - a discussion of the impact of the proposed merger on EQR.

The presentation also included a pro forma merger analysis, a share price
analysis, a public trading multiples analysis, a selected transactions analysis,
a share trading history analysis, an historical exchange ratio analysis, and a
net asset value analysis.

    The EQR Board of Trustees also discussed the advantages and disadvantages to
EQR of the merger. After extensive discussion, the EQR Board of Trustees
concluded that the advantages of the merger outweighed the risks and that the
consideration to be paid by EQR in connection with the merger was fair to EQR,
and the EQR Trustees who voted on the merger unanimously approved the merger
agreement and the related agreements.

    On June 30, 1999, a special meeting of the Lexford Board of Trustees was
held with Lexford Trustees, members of Lexford management, representatives of
Morgan Stanley and Brown Gibbons Lang, representatives of Ernst & Young LLP and
legal counsel present via telephone. At the meeting, the Lexford Board of
Trustees was updated on the status of discussions with EQR regarding the
potential merger transaction between Lexford and EQR. Mr. Bartling and others
reviewed with the Lexford Board of Trustees (1) the background of the proposed
merger and the material terms of this transaction, (2) pertinent due diligence
findings with respect to EQR, with particular emphasis on the current operations
and properties of EQR, and (3) the potential benefits as well as the risks of
the

                                       20
<PAGE>
proposed merger transaction as described below under "--Advantages and
Disadvantages of the Merger; Recommendation of the Lexford Board of Trustees."

    Representatives of Morgan Stanley presented a financial analysis of the
merger transaction and delivered Morgan Stanley's oral opinion, subsequently
confirmed in writing dated June 30, 1999, to the Lexford Board of Trustees, that
as of June 30, 1999, based upon and subject to the facts and circumstances as
they existed at that time, and based upon and subject to certain assumptions,
factors and limitations, the consideration to be received by holders of Lexford
common shares pursuant to the merger agreement was fair from a financial point
of view to such shareholders. Representatives of Brown Gibbons Lang verbally
advised the Lexford Board of Trustees to approve the merger agreement and the
merger.

    Lexford's legal counsel made a presentation to the Lexford Board of Trustees
in which it explained the material terms of the proposed transaction and the
merger agreement and advised the Lexford Board of Trustees on certain legal
issues raised by the proposed merger transaction, including its duties in
connection with such transaction.

    Following these presentations, and after extensive discussion of the
advantages and disadvantages of the proposed merger as described under
"--Advantages and Disadvantages of the Merger; Recommendation of the Lexford
Board of Trustees," the Lexford Board of Trustees concluded that the advantages
of the merger outweighed the risks, and unanimously approved the merger
agreement and all transactions contemplated by the merger agreement.

    After final negotiations, the merger agreement, dated as of June 30, 1999,
was executed by EQR and Lexford.

ADVANTAGES AND DISADVANTAGES OF THE MERGER;
RECOMMENDATION OF THE EQR BOARD OF TRUSTEES

    The EQR Board of Trustees believes that the merger, including the
consideration, is fair and in the best interests of EQR and its shareholders.
Accordingly, the EQR Trustees who voted on the merger unanimously approved the
merger and unanimously recommended approval of the merger by the shareholders of
EQR.

    ADVANTAGES

    In reaching this determination, the EQR Board of Trustees reviewed
information provided by EQR management, legal counsel and accountants and
considered a number of factors. The material factors that the EQR Board of
Trustees considered in approving the merger, which it deemed favorable, are:

    1.  LEADERSHIP POSITION IN MULTIFAMILY PROPERTY INDUSTRY. The EQR Board of
       Trustees' belief that the merger would solidify EQR's leadership position
       in the multifamily property industry. The EQR Board of Trustees viewed
       this as favorable because, based upon the number of properties owned by
       EQR and Lexford as of June 30, 1999 the combined entity would own or have
       interests in and operate approximately 1,088 multifamily properties
       consisting of 230,224 apartment units.

    2.  INCREASE IN MARKET CAPITALIZATION. Upon completion of the merger, the
       combined market capitalization of EQR would increase to approximately $13
       billion.

    3.  INCREASE IN PRO FORMA NET INCOME. On a pro forma basis for the three
       months ended March 31, 1999, the merger increases EQR's net income per
       common share.

                                       21
<PAGE>
    4.  GREATER GROWTH OPPORTUNITIES. The EQR Board of Trustees' belief that as
       a result of the merger, EQR would be a larger company, which would
       facilitate combinations with other public or private entities.

    5.  USE OF EQUITY RATHER THAN CASH. The fact that the merger could be
       effected through the issuance of new equity valued, as of June 29, 1999
       (based upon the closing price of EQR common shares), at approximately
       $198.8 million, rather than cash.

    6.  TERMS OF THE MERGER AGREEMENT. The EQR Board of Trustees' belief that
       the terms of the merger are fair to EQR and its shareholders.

    7.  TAX-FREE NATURE OF THE MERGER. Under generally accepted accounting
       principles, the merger will be accounted for as a purchase, and for
       federal income tax purposes the merger will be a tax-free transaction.
       The EQR Board of Trustees views this as favorable because, generally, no
       gain or loss will be recognized in the merger by either EQR or the
       shareholders of EQR.

    8.  NEW MARKET. The entrance of EQR into the low density, ranch style
       apartment market is consistent with EQR's long range goal of entering
       into new sectors where it does not currently conduct a material amount of
       business. EQR's entrance into this market sector provides EQR with
       further diversification within the multifamily properties business.

    9.  FIXED EXCHANGE RATIO. The fixed exchange ratio and the possibility that
       the value of the consideration to be paid to Lexford common shareholders
       in the merger could decrease.

    DISADVANTAGES

    The EQR Board of Trustees also considered certain potentially negative
factors which could result from the merger. These included:

    1.  COST OF THE TRANSACTION. The significant cost involved in connection
       with the completion of the merger and the substantial management time and
       effort required to complete the merger.

    2.  INCREASE OF DEBT. By assuming Lexford's debt pursuant to the merger,
       EQR's total debt will increase by approximately $555 million or 12% on a
       pro forma basis as of March 31, 1999 and EQR's debt to total market
       capitalization ratio will increase from 40% to 42% as of March 31, 1999.
       This increase could adversely affect EQR's ability to obtain additional
       debt financing in the future for working capital, capital expenditures,
       acquisitions, development or other general purposes, making EQR more
       vulnerable to a downturn in business or the economy generally.

    3.  BENEFITS NOT FULLY REALIZED. The risk that the anticipated benefits of
       the merger might not be fully realized.

    4.  NEW MARKET. Lexford's business of providing low density, ranch style
       apartments represents a market sector that EQR has not generally served.

    5.  FIXED EXCHANGE RATIO. The fixed exchange ratio and the possibility that
       the value of the consideration to be paid to Lexford common shareholders
       in the merger could increase.

    The EQR Board of Trustees did not believe that the negative factors were
sufficient, either individually or in the aggregate, to outweigh the advantages
of the merger.

    OTHER CONSIDERATIONS

    The EQR Board of Trustees viewed as adequate the conditions to the closing
of the merger contained in the merger agreement, including the condition that no
change in the financial condition,

                                       22
<PAGE>
business or operations of Lexford will have occurred that would have a material
adverse effect on Lexford.

    In view of the wide variety of factors considered in connection with its
evaluation of the merger, the EQR Board of Trustees did not find it practicable
to, and did not, quantify or otherwise attempt to assign relative weight to the
specific factors considered in reaching its determination.

    RECOMMENDATION

    The EQR Board of Trustees believes that the merger is fair to and in the
best interests of EQR and its shareholders and recommends that the EQR common
shareholders vote FOR the merger.

    In the event that the merger is not consummated for any reason, EQR will
continue to pursue its business objectives.

ADVANTAGES AND DISADVANTAGES OF THE MERGER;
RECOMMENDATION OF THE LEXFORD BOARD OF TRUSTEES

    At special meetings of the Lexford Board of Trustees held on June 23 and 30,
1999, members of Lexford's management and legal counsel made presentations
concerning the proposed merger and related transactions, and Lexford management
addressed the business and prospects of Lexford and EQR. Representatives of
Morgan Stanley also made a presentation at each of these meetings concerning the
same matters. As part of its deliberations, the Lexford Board of Trustees
considered and analyzed a number of important factors concerning EQR, including
the age, condition and geographic diversification of EQR's assets, the depth and
experience of its management, its credit rating, its capital structure and its
financial situation, including funds from operations ("FFO"), earnings before
interest, taxes, depreciation and amortization ("EBITDA") and debt to total
market capitalization ratio, as well as EQR's future prospects and growth
opportunities as a combined company with Lexford.

    The Lexford Board of Trustees also received a report from Morgan Stanley and
considered the proposed exchange ratio of 0.463 of an EQR common share for each
Lexford common share in terms of trading prices, implied ratios and values over
recent stock market trading activity as well as the multiples inherent in the
EQR price per common share as applied to 1999 and 2000 estimated funds from
operations, adjusted funds from operations (sometimes referred to as cash
available for distribution) and EBITDA. At the June 23, 1999 meeting, Morgan
Stanley made a presentation to the Lexford Board of Trustees regarding the
valuation of EQR's common shares. At the June 30, 1999 meeting, Morgan Stanley
made a presentation to the Lexford Board of Trustees regarding the analysis
described under "Opinion of the Financial Advisor for Lexford." Also at the June
30, 1999 meeting, Morgan Stanley rendered its oral opinion, later confirmed in
writing, that, as of that date, the consideration to be received by the holders
of Lexford common shares pursuant to the merger agreement was fair from a
financial point of view to the Lexford shareholders. The Lexford Board of
Trustees also reviewed and discussed the pro forma financial information
compiled by preparing financial data showing the effect of the merger and noted
that it was reasonable to expect that as a result of the merger, EQR's funds
from operations per common share would increase, thereby providing Lexford
shareholders with potential share value appreciation following the consummation
of the merger.

    The Lexford Board of Trustees also reviewed the terms of the merger
agreement with Lexford's management and Lexford's financial and legal advisors.
At the June 30 meeting, the Lexford Board of Trustees determined, by unanimous
vote, that the merger was fair to, and in the best interests of, Lexford and its
shareholders, approved and adopted the merger agreement and the transactions
contemplated by the merger agreement, and resolved to recommend that Lexford's
shareholders approve the merger.

                                       23
<PAGE>
    ADVANTAGES

    In making its determination with respect to the merger, the Lexford Board of
Trustees also considered, among other things, that:

    1.  the exchange ratio reflects a premium over prevailing share prices for
Lexford common shares through the first five months of 1999 and EQR may have a
higher growth rate in the future, and has a significantly lower debt to market
capitalization ratio, than Lexford;

    2.  in the opinion of the Lexford Board of Trustees, the merger offers
Lexford's shareholders an opportunity to take advantage of the general trend in
the real estate industry towards consolidation through a significant
participation in a larger, more geographically diverse real estate company with
greater potential for long-term appreciation. In this regard, the Lexford Board
of Trustees considered the discussions management conducted with investment
banking firms regarding possible strategic combinations, as well as EQR's size,
financial resources, geographic diversification, credit rating, access to lower
cost capital and the expertise and experience of EQR's management;

    3.  the anticipated increase in the geographic distribution of the apartment
assets of, the anticipated increased financial strength of, and the anticipated
cost savings and operating efficiencies available to, EQR following the merger,
particularly from a reduction of general and administrative overhead expenses,
the costs of capital, bulk purchasing, advertising and property management,
which would benefit the shareholders of Lexford who, as a result of the merger,
would become shareholders of EQR;

    4.  the terms of the merger agreement, which the Lexford Board of Trustees
believes to be fair to Lexford and its shareholders, which terms were reached
through extensive arms-length negotiations. In this regard, the Lexford Board of
Trustees noted that the exchange ratio fairly reflected the relative
contributions of both companies to the combined entity and represented an
attractive opportunity for shareholders to continue their investment and
maintain their receipt of quarterly distributions, but with significantly
expanded geographic diversification;

    5.  following the merger, EQR will have significantly greater market
capitalization than Lexford, coupled with a substantially lower debt to total
market capitalization ratio, which could provide shareholders increased
liquidity after the merger;

    6.  the "stock-for-stock," rather than "cash-for-stock" structure of the
merger, which, among other things, will cause the merger to be tax-free to the
shareholders of Lexford;

    7.  the opinion, analyses and presentations of Morgan Stanley;

    8.  the opinion of Morgan Stanley that the consideration to be received by
holders of Lexford common shares pursuant to the merger agreement is fair from a
financial point of view to the Lexford shareholders;

    9.  the advice of Brown Gibbons Lang to the Lexford Board of Trustees to
approve the merger agreement and the merger; and

    10. the fixed exchange ratio and the possibility that the value of the
consideration to be received by the Lexford shareholders could increase.

    DISADVANTAGES

    The Lexford Board of Trustees also considered certain potentially negative
factors in its deliberations concerning the merger, including, among others:

    1.  the risk that the anticipated benefits of the merger might not be fully
realized;

    2.  the significant costs involved with completing the merger;

                                       24
<PAGE>
    3.  the substantial management time and effort required to complete the
merger;

    4.  the fixed exchange ratio and the possibility that the value of the
consideration to be received by the Lexford shareholders could decrease;

    5.  the possibility that Lexford may be required, if the merger agreement is
terminated under certain circumstances, to pay EQR the break-up fee or the
expense fee or both; and

    6.  that the distribution rate paid with respect to 0.463 of an EQR common
share for the first two quarters of 1999 is approximately 24% less than the
distribution rate paid with respect to a Lexford common share for those
quarters.

    In addition to the above factors, the Lexford Board of Trustees was aware of
and evaluated the actual and potential conflicts of interest, including the
compensation arrangements benefitting members of Lexford's management and the
Lexford Board of Trustees. See "Interests of Lexford Trustees and Management in
the Merger." In view of the wide variety of factors considered by the Lexford
Board of Trustees, the Lexford Board of Trustees did not quantify or otherwise
attempt to assign relative weights to the specific factors considered in making
its determination. However, after due consideration of their obligations, in the
unanimous view of the Lexford Board of Trustees, the potential conflicts of
interest and potentially negative factors considered by it were not sufficient,
either individually or collectively, to outweigh the positive factors considered
by it in its deliberations relating to the merger.

    RECOMMENDATION

    The Lexford Board of Trustees believes that the merger is fair to and in the
best interests of Lexford and its shareholders and recommends that the Lexford
common shareholders vote FOR the merger.

OPINION OF THE FINANCIAL ADVISOR FOR LEXFORD

    Lexford retained Morgan Stanley to act as its financial advisor with respect
to strategic alternatives and related matters, based on Morgan Stanley's
qualifications, reputation and expertise. At a meeting of the Lexford Board of
Trustees on June 30, 1999, Morgan Stanley delivered its oral opinion to the
Lexford Board of Trustees, subsequently confirmed in writing, that as of such
date, and subject to the various considerations set forth in its opinion, the
consideration to be received by the holders of Lexford common shares pursuant to
the merger agreement is fair from a financial point of view to the Lexford
shareholders. No limitations were imposed by Lexford's Board of Trustees upon
Morgan Stanley with respect to the investigations made or procedures followed by
it in delivering its opinion.

    A COPY OF THE MORGAN STANLEY OPINION, DATED AS OF JUNE 30, 1999, WHICH
DESCRIBES, AMONG OTHER THINGS, THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED,
MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS
APPENDIX C TO THIS JOINT PROXY STATEMENT/PROSPECTUS. THE MORGAN STANLEY OPINION
IS DIRECTED ONLY TO THE LEXFORD BOARD OF TRUSTEES AND THE FAIRNESS OF THE
CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF LEXFORD COMMON SHARES PURSUANT TO
THE MERGER AGREEMENT FROM A FINANCIAL POINT OF VIEW TO SUCH HOLDERS AS OF THE
DATE OF MORGAN STANLEY'S OPINION, DOES NOT ADDRESS ANY OTHER ASPECT OF THE
MERGER, NOR DOES IT CONSTITUTE A RECOMMENDATION TO ANY LEXFORD SHAREHOLDER AS TO
HOW SUCH SHAREHOLDER SHOULD VOTE AT THE SPECIAL MEETING OF LEXFORD SHAREHOLDERS.
THE SUMMARY OF THE MORGAN STANLEY OPINION DESCRIBED IN THIS JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF THE MORGAN STANLEY OPINION. SHAREHOLDERS OF LEXFORD ARE URGED TO, AND SHOULD,
READ THE MORGAN STANLEY OPINION CAREFULLY AND IN ITS ENTIRETY.

    In connection with rendering its opinion, Morgan Stanley, among other
things:

    - reviewed certain publicly available financial statements and other
      business and financial information of Lexford and EQR, respectively;

                                       25
<PAGE>
    - reviewed certain internal financial statements and other financial and
      operating data concerning Lexford and EQR prepared by the managements of
      Lexford and EQR, respectively;

    - analyzed certain financial forecasts for Lexford and EQR prepared by the
      managements of Lexford and EQR, respectively;

    - discussed the past and current operations and financial condition and the
      prospects of Lexford and EQR, including information relating to certain
      strategic, financial and operational benefits anticipated from the merger,
      with senior executives of Lexford and EQR, respectively;

    - reviewed the pro forma impact of the merger on Lexford's and EQR's funds
      from operations per share, consolidated capitalization and financial
      ratios;

    - reviewed the reported prices and trading activity for the Lexford common
      shares and the EQR common shares;

    - compared the financial performance of EQR and the prices and trading
      activity of EQR common shares with those of certain other comparable
      publicly-traded companies and their securities;

    - reviewed the financial terms, to the extent publicly available, of certain
      transactions deemed relevant;

    - discussed with senior executives of Lexford and EQR their strategic
      objectives of the merger and the plan for the combined company;

    - participated in discussions and negotiations among representatives of
      Lexford, EQR and certain other parties and their financial and legal
      advisors;

    - reviewed drafts of the merger agreement and certain related documents; and

    - performed such other analyses and considered such other factors as Morgan
      Stanley deemed appropriate.

    In rendering its opinion, Morgan Stanley assumed and relied upon without
independent verification the accuracy and completeness of the information
supplied or otherwise made available to it by Lexford and EQR for the purposes
of the opinion. With respect to the financial forecasts, Morgan Stanley assumed
that they had been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of Lexford
and EQR. Morgan Stanley relied upon, without independent verification, the
assessment of the managements of Lexford and EQR of the strategic, financial and
operational benefits expected to result from the merger. Morgan Stanley did not
make any independent valuation or appraisal of the assets or liabilities of
Lexford or EQR, nor was it furnished with any such appraisals. Morgan Stanley's
opinion is necessarily based on financial, economic, market and other conditions
as in effect on, and the information made available to Morgan Stanley as of, the
date of its opinion. In addition, Morgan Stanley has assumed that the merger
will be treated as a tax-free reorganization pursuant to the Internal Revenue
Code.

    The following is a summary of the material financial and comparative
analyses performed by Morgan Stanley in connection with providing the opinion to
the Lexford Board of Trustees on June 30, 1999. Some of these summaries of
financial analyses include information presented in tabular format. In order to
understand fully the financial analyses used by Morgan Stanley, the tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses.

    STOCK TRADING HISTORY.  Morgan Stanley reviewed the historical trading
prices for Lexford and noted that the 52-week low and high prices of Lexford
common shares through June 2, 1999 were $15.50 and $21.50, respectively. Morgan
Stanley also reviewed the historical trading prices for EQR and

                                       26
<PAGE>
noted that the 52-week low and high prices of EQR common shares through June 2,
1999 were $34.69 and $49.63, respectively. After June 2, 1999, Lexford common
shares intermittently experienced significant increases in trading volume and,
to a lesser extent, price appreciation. For that reason Morgan Stanley
considered the closing price on June 2, 1999 to be the most recent price for
Lexford common shares unaffected by market fluctuations.

    Morgan Stanley reviewed the premium obtained by computing the percentage
excess of the product of various closing prices of EQR common shares and 0.463
over the various closing prices of Lexford common shares. Based on the closing
prices of Lexford common shares and EQR common shares as of June 2, 1999, the
premium was 24.2%. Based on the closing price of EQR common shares on June 28,
1999 and the closing price of Lexford common shares on June 2, 1999 and the
average closing price of Lexford common shares in 1999 through June 2, the
premia were 17.5% and 19.9%, respectively. Based on the closing prices of EQR
common shares for the ten, thirty, and sixty trading days ended June 28, 1999
and the closing price of Lexford common shares on June 2, 1999, the premia were
18.0%, 21.1% and 18.6%, respectively.

    NET ASSET VALUE.  Morgan Stanley estimated the net asset value of Lexford
based on a property-by-property analysis. For consolidated properties, a range
of capitalization rates based on recent, comparable market transactions was
applied to estimates of 1999 net operating income. A range of values were also
used for recurring capital expenditures per unit and deferred capital
expenditures, $250 to $400 and $10 million to $30 million, respectively. The
non-modular properties were valued in various ways. The Guilford property was
valued at the capital invested net of Lexford's share of losses to date. Hidden
Pointe was valued by applying a capitalization rate to 1999 estimated net
operating income and distributing the equity value between Lexford and the other
partners. Keystone Ranch was valued at book value plus a 10% profit on the
development. Unconsolidated properties were valued using a range of
capitalization rates, assigning a 50 basis point capitalization rate premium to
these properties over the consolidated properties due to their complex structure
and asset quality. The gross value of the assets was reduced by the estimated
value of the outstanding debt marked-to-market and estimated transaction costs
to arrive at a net asset value range of $17.60 to $22.28 per share.

    Morgan Stanley also reviewed the net asset value estimates for EQR as
reported by Wall Street analysts and industry reporters. These values ranged
from $42.82, reported by Realty Stock Review on June 4, 1999, to $49.01,
reported by Merrill Lynch on May 5, 1999. In addition, analysts reported a range
of price targets for EQR of $50.00 to $54.00. These net asset value estimates
and price targets were compared to the closing trading price of EQR common
shares on June 28, 1999 of $45.375.

    DISCOUNTED CASH FLOW.  Morgan Stanley performed discounted cash flow
analyses of Lexford based upon projections provided by Lexford. These discounted
cash flow analyses may be considered to represent continuation analyses for
Lexford. Morgan Stanley performed two separate discounted cash flow analyses:
dividend discount and free cash flow. The dividend discount model discounted
estimated dividends per share for the years 1999 through 2003, using discount
rates reflecting an expected equity total return and applying terminal multiples
on 2004 FFO. The expected equity total return was determined based upon
Lexford's and the comparable companies' dividend yields plus expected FFO growth
rate. The free cash flow methodology discounted all available cash flow before
interest and dividends for the years 1999 through 2003, using discount rates
reflecting a weighted average cost of capital and applying terminal multiples on
2004 EBITDA. The following table presents the results of Morgan Stanley's
analyses of Lexford.

In addition, Morgan Stanley performed discounted cash flow analyses of EQR pro
forma for the merger based upon projections provided by Lexford and EQR. The
same methodology was applied to EQR as was used to value Lexford. The values for
EQR common shares produced by these analyses were compared to the closing
trading price of EQR common shares on June 28, 1999 of $45.375. The following
table presents the results of Morgan Stanley's analyses of EQR.

</TABLE>

    HISTORICAL IMPLIED EXCHANGE RATIOS.  Morgan Stanley computed the historical
ratios of the closing share prices of Lexford to EQR from June 2, 1997 through
June 2, 1999 and noted the approximate averages of such ratios for the two-year,
one-year, six-month, three-month and one-month periods, respectively, ended June
2, 1999 as compared to the exchange ratio of 0.463.

Three-month            0.40
One-month              0.37
</TABLE>

    PRO FORMA MERGER ANALYSIS.  Morgan Stanley performed an analysis of the
effect of the merger on EQR's pro forma FFO per share for the projected years
ended December 31, 1999 through December 31, 2003 which assumed that the merger
had been consummated on January 1, 1999. Morgan Stanley combined the projected
operating results of Lexford and EQR and estimated cost savings, based on
internal estimates provided by each company, to arrive at the pro forma
projected FFO. Morgan Stanley's analysis was based upon the exchange ratio of
0.463 for holders of Lexford common shares and estimated annual expense savings
resulting from the merger and expected to arise primarily from savings in
duplicative public company and general and administrative expenses. Morgan
Stanley then compared this result with the stand-alone FFO per share to
determine the projected pro forma impact of the merger on the pro forma FFO per
EQR common share. This analysis indicates that the pro forma EQR FFO per share
in each of 1999 through 2003 would be higher than the stand-alone projections
for EQR of FFO for each of those years if the merger did not occur.

    ANALYSES OF SELECTED COMPARABLE TRANSACTIONS.  Morgan Stanley compared the
principal terms of the merger with those of selected other comparable
transactions listed below.

</TABLE>

    Based on the average trading prices for the ten-trading day period ending
five trading days prior to the public announcement of each of these
transactions, to estimate transaction premia unaffected by market fluctuations,
the average premium paid by the surviving company for the company being acquired
in the public multi-family REIT transactions was 14.0% and ranged from (1.0)% to
28.6% for the selected transactions. Morgan Stanley also examined the premia
paid relative to an acquiree's 52-week high and all time high common share
prices. Based on the closing prices of Lexford common shares and EQR common
shares as of June 2, 1999, the premium to be paid by EQR pursuant to the merger
is 24.2%. The per share value range for Lexford common shares based on the
comparable transactions analyses was determined to be between $18.77 and $24.99.

    ANALYSES OF SELECTED COMPARABLE PUBLICLY TRADED COMPANIES.  Morgan Stanley
reviewed the trading statistics of selected comparable publicly traded apartment
REITs, selected on the basis of size, portfolio characteristics and geographic
diversity, to estimate the value of EQR. For EQR, comparable companies selected
consisted of Apartment Investment and Management Co., Archstone Communities
Trust, AvalonBay Communities, BRE Properties, and Post Properties. Based on
consensus security analyst estimates for 1999 and 2000, as reported by First
Call, and June 28, 1999 closing prices, the trading multiples of 1999 projected
FFO per share ranged from 10.5x to 11.2x, and the trading multiples of 2000
projected FFO per share selected for this analysis ranged from 9.5x to 10.2x.
Applying these ranges of multiples to the sum of the First Call consensus 1999
and 2000 FFO for EQR and the assumed accretion from the Lexford transaction
($4.50 in 1999 and $4.95 in 2000) resulted in ranges of values from $47.25 to
$50.45 and $47.02 to $50.70. Based on current dividend payments and June 28,
1999 closing prices, the dividend range of comparable apartment REITs was 5.9%
to 6.8%. Applying this range of yield to EQR's projected dividend resulted in a
range of values from $43.09 to $49.94.

    Morgan Stanley reviewed the multiple to total return ratios of the
comparable publicly traded REITs. The multiple to total return ratios were
obtained by dividing the FFO trading multiple for each company by its total
return, which is the sum of its annualized reported 1999 dividend yield and the
consensus security analyst estimate of the long term growth rate as reported by
First Call. Based on 2000 estimated FFO of EQR of $4.95 (pro forma to the
Lexford transaction) and the multiple to total return ratio range selected of
0.60 to 0.65, EQR is valued at a range of $45.31 to $49.04.

    Based on research estimates of 1999 and 2000 EBITDA, and June 28, 1999
closing prices, the trading multiples of 1999 projected EBITDA ranged from 12.5x
to 12.8x, and the trading multiples of 2000 projected EBITDA ranged from 11.0x
to 11.3x. Applying these ranges of multiples to the EQR

                                       29
<PAGE>
estimates of 1999 and 2000 EBITDA and assuming acquisition of Lexford (25%
incremental EBITDA in 1999 and full pro forma EBITDA in 2000) resulted in ranges
of values from $50.81 to $52.78 and
$48.47 to $50.54.

    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of all of its
analyses as a whole and did not attribute any particular weight to any
particular analysis or factor considered by it. Furthermore, selecting any
portion of Morgan Stanley's analyses, without considering all analyses, would
create an incomplete view of the process underlying the Morgan Stanley opinion.
In addition, Morgan Stanley may have deemed various assumptions more or less
probable than other assumptions, so that the ranges of valuations resulting from
any particular analysis described above should not be taken to be Morgan
Stanley's view of the actual value of EQR or Lexford.

    In performing its analysis, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Lexford or EQR. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
values, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of Morgan Stanley's
analysis of the fairness of the consideration to be received by the holders of
Lexford common shares pursuant to the merger agreement from a financial point of
view to such holders and were provided to the Lexford Board of Trustees in
connection with the delivery of the Morgan Stanley opinion. The analyses do not
purport to be appraisals or to reflect the prices at which Lexford or EQR might
actually be sold. In addition, as described above, the Morgan Stanley opinion
was one of many factors taken into consideration by the Lexford Board of
Trustees in making its determination to approve the merger. The exchange ratio
pursuant to the merger agreement was determined through arm's length
negotiations between Lexford and EQR and was approved by the Lexford Board of
Trustees.

    Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for corporate, estate and other purposes. In the
ordinary course of its trading, brokerage and financing activities, Morgan
Stanley and its affiliates may, at any time, have a long or short position in,
and buy and sell the debt or equity securities and senior loans of Lexford or
EQR for its account or the account of its customers. Morgan Stanley and its
affiliates have, in the past, provided financial advisory services to Lexford
and have received fees for the rendering of such services.

    In connection with the services of Morgan Stanley as financial advisor to
the Lexford Board of Trustees with respect to the merger and related matters,
Lexford has agreed to pay Morgan Stanley certain fees. If a transaction is
accomplished, Lexford has agreed to pay Morgan Stanley a transaction fee. The
transaction fee will be approximately $4.0 million. In addition, Lexford has
agreed to reimburse Morgan Stanley for its reasonable out-of-pocket expenses
(including the fees and expenses of its attorneys) related to the engagement and
to indemnify Morgan Stanley and certain related persons against certain
liabilities, including certain liabilities under the federal securities laws,
and expenses arising out of its engagement and the transactions in connection
therewith.

    - as of the closing date, neither EQR or Lexford, nor any of their
      subsidiaries, will have suffered a material adverse change in its
      business, properties, assets, financial condition or results of operations
      taken as a whole;

    - each of EQR and Lexford shall have received an opinion from counsel to the
      other party, stating that commencing with its taxable year ended December
      31, 1992, in the case of EQR, and December 31, 1998, in the case of
      Lexford, each of EQR and Lexford, respectively, was organized and has
      operated in conformity with the requirements for qualification as a REIT
      under the Internal Revenue Code;

    - each of EQR and Lexford shall have received an opinion of counsel to the
      other party, dated as of the closing date, to the effect that the merger
      will qualify as a reorganization under the provisions of Section 368(a) of
      the Internal Revenue Code;

    - each of EQR and Lexford shall have received a "comfort letter" from the
      other party's accountants;

    - each of EQR and Lexford shall have received an opinion from counsel to the
      other party addressing specified issues set forth in the merger agreement;

    - the receipt of all consents and waivers from third parties necessary in
      connection with the completion of the transactions contemplated by the
      merger agreement; and

    - the obligation of EQR to complete the merger is subject to (1) certain
      fees related to the merger not exceeding specified amounts and (2) Lexford
      having filed its 1998 federal tax return that includes an election to be
      taxed as a REIT in accordance with the Internal Revenue Code.

NO APPRAISAL RIGHTS

    The common shareholders of EQR and Lexford are not entitled to dissenting
shareholders' appraisal rights under Maryland law. Maryland law does not provide
appraisal rights to shareholders of a company in connection with a merger if, on
the record date for determining shareholders entitled to vote on a merger, the
company's shares are listed on a national securities exchange, such as the NYSE.
All of the common shares of EQR and Lexford outstanding on the record date for
determining shareholders entitled to vote on the merger were listed on the NYSE.

REGULATORY MATTERS

    EQR and Lexford believe that the merger can be completed without
notification being given or information being furnished to the Federal Trade
Commission or the Antitrust Division of the Department of Justice pursuant to
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. EQR and
Lexford also believe that no waiting period requirements under this Act are
applicable to the merger. However, at any time before or after the completion of
the merger, either the Antitrust Division or the FTC could take whatever action
under the antitrust laws it deems necessary or desirable in the public interest,
or additional parties could take action under the antitrust laws including
seeking to enjoin the merger. EQR and Lexford believe that completion of the
merger would not violate any antitrust laws. However, a challenge to the merger
on antitrust grounds may be made, and, if a challenge is made, the result will
be uncertain.

TERMINATION PROVISIONS

    The merger agreement may be terminated at any time prior to the acceptance
for record of the Articles of Merger by the Department, whether before or after
approval of the merger by the shareholders of Lexford and EQR:

    - by the mutual written consent of EQR and Lexford;

    - if the merger has not been completed by December 31, 1999 (subject to
      extension to March 31, 2000 in specified circumstances), provided that the
      terminating party has not materially breached its obligations under the
      merger agreement in a manner that proximately contributed to the merger
      not being completed by the relevant date;

    - upon a breach by the non-terminating party of any representation,
      warranty, covenant, obligation or agreement set forth in the merger
      agreement, such that specified conditions set forth in the merger
      agreement would be incapable of being satisfied by December 31, 1999 (or
      as otherwise extended);

    - if the approval of the shareholders of EQR or Lexford has not been
      obtained upon a vote at the meetings of shareholders; or

    - if an order, decree, judgment or other action preventing completion of the
      merger has become final and non-appealable.

    The merger agreement may be terminated by Lexford if, prior to the Lexford
special meeting, the Lexford Board of Trustees withdraws or modifies its
approval or recommendation of the merger in connection with, or approves or
recommends, a "Superior Acquisition Proposal," which the merger agreement
defines as a bona fide acquisition proposal by a third party that a majority of
the members of the Lexford Board of Trustees determines in good faith to be more
favorable to Lexford's shareholders from a financial point of view than the
merger and which the Lexford Board of Trustees determines is reasonably capable
of being consummated.

    The merger agreement may be terminated by EQR if (1) prior to the Lexford
special meeting, the Lexford Board of Trustees withdraws or modifies in any
manner adverse to EQR its approval or recommendation of the merger or the merger
agreement in connection with, or approves or recommends, a Superior Acquisition
Proposal, or (2) Lexford enters into a definitive agreement with respect to any
"Acquisition Proposal", which the merger agreement defines as a merger,
acquisition, tender offer, exchange offer, consolidation, sale of assets or
similar transaction involving all or any significant portion of the assets or
any equity securities of Lexford or any of its subsidiaries, other than the
transactions contemplated by the merger agreement.

                                       33
<PAGE>
TERMINATION FEE AND EXPENSES

    The merger agreement provides for the payment, in specified circumstances,
of a break-up fee of $8 million and an expense fee equal to the out-of-pocket
expenses incurred in connection with the merger agreement of up to $4 million.

    BREAK-UP FEE

    Lexford is required to pay the break-up fee to EQR if (1) the merger is not
consummated, other than due to the termination of the merger agreement by:

    - the mutual written consent of the EQR and Lexford Boards of Trustees;

    - either party, upon the failure by EQR to obtain the required shareholder
      approval;

    - Lexford, upon a breach of any representation, warranty, covenant,
      obligation or agreement on the part of EQR resulting in a "material
      adverse effect" to EQR;

    - EQR, if the merger has not been completed by December 31, 1999 (or, under
      limited circumstances, March 31, 2000); or

    - under limited circumstances, Lexford, if the merger has not been completed
      by March 31, 2000; and

(2) at the time of the termination of the merger agreement an Acquisition
Proposal has been received by Lexford, and either prior to the termination of
the merger agreement or within 12 months thereafter, Lexford or any of its
subsidiaries enters into any written Acquisition Proposal which is subsequently
consummated.

    Any break-up fee would be paid as compensation and liquidated damages for
the loss suffered by EQR as a result of the failure of the merger to be
consummated and to avoid the difficulty of determining damages under the
circumstances. Neither party shall have any liability to the other after payment
of the break-up fee.

    EXPENSE FEE

    Lexford is obligated to pay EQR the expense fee if the merger agreement is
terminated due to:

    - the Lexford Board of Trustees having withdrawn or modified its approval or
      recommendation of the merger or the merger agreement in connection with,
      or having approved or recommended, a Superior Acquisition Proposal; or

    - Lexford having entered into a definitive agreement with respect to any
      Acquisition Proposal.

    Additionally, if the merger agreement is terminated due to:

    - a breach of any representation, warranty, covenant, obligation or
      agreement by Lexford or EQR; or

    - failure by either Lexford or EQR to obtain the required shareholder
      approval,

then the breaching party, or the party that failed to obtain such shareholder
approval, shall pay to the other party an amount equal to the expense fee.

    Except as described above, each of EQR and Lexford is responsible for its
own costs and expenses incurred in connection with the merger agreement and the
transactions contemplated thereby, except that (1) all SEC filing fees incurred
in connection with the merger shall be paid 50% by Lexford and 50% by EQR and
(2) all printing costs shall be paid by EQR and Lexford in proportion to the
number

                                       34
<PAGE>
of proxy statements required by each of EQR and Lexford to complete the mailings
of the proxy statements to their shareholders.

NO SOLICITATION OF OTHER TRANSACTIONS

    Lexford has agreed that it will not initiate, solicit or encourage any
inquiries or the making of any offer with respect to a merger, acquisition,
tender offer, exchange offer, consolidation, sale of assets or similar
transactions involving all or any significant portion of the assets or any
equity securities of it or any of its subsidiaries, other than the merger.

    Notwithstanding the above restrictions, the merger agreement does not
prohibit Lexford from entering into discussions with respect to an unsolicited
proposal if the Lexford Board of Trustees determines in good faith that this
action is required by Lexford's legal duties to its shareholders.

CONVERSION OF SHARES

    At the completion of the merger, each Lexford common share outstanding
immediately prior to the completion of the merger will cease to be outstanding
and will automatically be converted into 0.463 of an EQR common share. Each
holder of a certificate evidencing any such shares will cease to have any rights
with respect thereto, except the right to receive:

    - a certificate evidencing EQR common shares;

    - any cash, without interest, instead of fractional EQR common shares; and

    - any dividends and distributions declared with respect to the Lexford
      common shares with a record date prior to the completion of the merger.

    The issuance, terms and conditions of the EQR common shares issued in
connection with the merger will be governed by EQR's Declaration of Trust. For a
detailed description of the provisions of EQR's Declaration of Trust, see
"Comparison of Rights of Shareholders."

APPOINTMENT OF EXCHANGE AGENT

    In order to facilitate distribution to Lexford shareholders of certificates
evidencing EQR common shares, EQR will appoint, and enter into an agreement
with, EquiServe LP, an affiliate of BankBoston, N.A., to act as exchange agent
for purposes of distributing to Lexford shareholders the certificates evidencing
EQR common shares.

EXCHANGE OF CERTIFICATES

    Lexford shareholders should not tender their certificates evidencing Lexford
common shares with their proxy. Promptly after the completion of the merger, the
exchange agent will mail transmittal materials to all Lexford shareholders,
including a letter of transmittal for use in exchanging certificates evidencing
Lexford common shares for certificates evidencing EQR common shares. As soon as
practicable after the letter of transmittal is properly completed and returned
to the exchange agent, with the certificates evidencing Lexford common shares,
the person specified in the letter of transmittal will receive certificates for
the number of whole EQR common shares and, to the extent applicable, a check in
payment of any cash instead of fractional EQR common shares, to which such
person is entitled as a result of the merger. The letter of transmittal will
provide instructions for shareholders who have lost or misplaced their
certificates and wish to tender their shares.

    Each EQR common share for which Lexford common shares are exchanged in the
merger will be deemed to have been issued on the date of the completion of the
merger. Accordingly, Lexford shareholders who receive EQR common shares in the
merger will be entitled to receive any dividends or other distributions which
may be payable to all holders of record of EQR common shares with

                                       35
<PAGE>
respect to any record date after the date of the completion of the merger. Until
the certificate or certificates formerly evidencing such holder's Lexford common
shares have been surrendered in accordance with the procedures described above,
no holder of Lexford common shares will be entitled to receive certificates
evidencing EQR common shares or cash instead of fractional EQR common shares,
and no dividends or other distributions will be paid with respect to the EQR
common shares. At the time such surrender has been accomplished, a certificate
evidencing the appropriate number of EQR common shares will be issued and
accrued dividends and other distributions on such EQR common shares will be paid
without interest.

    Lexford dividends declared with a record date before the completion of the
merger will be paid in full on the payment date set by the Lexford Board of
Trustees, based upon the number of Lexford common shares owned on the record
date.

CONDUCT OF BUSINESS PENDING THE MERGER

    Except as contemplated by the merger agreement or consented to in writing by
EQR, Lexford will, and will cause each of its subsidiaries to conduct its
business only in the usual, regular and ordinary course and, among other things:

    - not amend its Declaration of Trust, Bylaws or comparable organizational
      document of any subsidiary;

    - not issue shares of beneficial interest or other equity interests, except
      upon exercise of previously outstanding options to purchase Lexford common
      shares;

    - not grant options relating to Lexford common shares;

    - limit any dividends to specified amounts;

    - not redeem any shares of capital stock;

    - not sell, lease or mortgage any material part of its assets;

    - not enter into any transaction which may result in total payments or
      liability in excess of $250,000 or aggregate commitments of $500,000; and

    - not increase any compensation of its current officers, trustees or
      employees earning more than $50,000 per year.

    Prior to the completion of the merger, except as contemplated by the merger
agreement or consented to in writing by Lexford, EQR will, and will cause each
of its subsidiaries to, among other things:

    - preserve its business;

    - confer on a regular basis with Lexford regarding specified material
      operational matters;

    - promptly notify Lexford of any material emergency or material change in
      EQR's business or operation; and

    - use its reasonable best efforts to continue to qualify as a REIT prior to
      the merger.

WAIVER AND AMENDMENT

    At any time before the merger, either party may:

    - extend the time for the performance of any of the obligations or other
      acts of the other party required by the merger agreement;

                                       36
<PAGE>
    - waive any inaccuracies in the representations and warranties contained in
      the merger agreement or in any document delivered pursuant to the merger
      agreement; and

    - waive compliance with any of the agreements or conditions for the benefit
      of the waiving party contained in the merger agreement.

    The merger agreement may be amended by actions taken by the Boards of
Trustees of EQR and Lexford, at any time before or after approval of the merger
agreement by the shareholders of EQR or Lexford and prior to the filing of the
Articles of Merger with the Department. After approval of the merger agreement
by the shareholders of EQR or Lexford, no amendment may be made which by law
requires the further approval of shareholders without obtaining this further
approval.

STOCK EXCHANGE LISTING

    EQR will apply to list the EQR common shares issuable in connection with the
merger on the NYSE. Approval of the listing of such shares on the NYSE, subject
to official notice of issuance, is a condition to the respective obligations of
EQR and Lexford to complete the merger.

ACCOUNTING TREATMENT

    The merger will be treated as a purchase in accordance with Accounting
Principles Board Opinion No. 16. Purchase accounting for a merger is the same as
the accounting treatment used for the acquisition of any group of assets. The
fair value of the consideration given by EQR in the merger will be used as the
valuation basis of the combination. The assets acquired and liabilities assumed
of Lexford will be recorded at their relative fair values as of the completion
of the merger. The financial statements of EQR will reflect the combined
operations of EQR and Lexford from the closing date.

SHARES AVAILABLE FOR RESALE

    The issuance of EQR common shares upon consummation of the merger will be
registered under the Securities Act. Such shares may be traded freely and
without restriction by those shareholders not deemed to be "affiliates" of
Lexford or EQR as that term is defined under the Securities Act. The term
"affiliates" is defined to mean persons who control, are controlled by or are
under common control with an issuer, including officers and directors of the
issuer and, generally, holders of ten percent or more of the issuer's equity
securities. This joint proxy statement/prospectus does not cover any resales of
EQR common shares received by affiliates of Lexford.

CONTRIBUTION OF ASSETS OF LEXFORD TO ERP OPERATING LIMITED PARTNERSHIP

    Promptly following the completion of the merger, the real properties owned
by Lexford prior to the merger and the equity interests in the partnership and
limited liability company subsidiaries of Lexford will be contributed by EQR to
ERP Operating Limited Partnership, in exchange for units of ERP Operating
Limited Partnership equal in number to the number of EQR common shares issued in
the merger to Lexford shareholders. The assets will be contributed to ERP
Operating Limited Partnership subject to the liabilities of Lexford and the
Lexford subsidiaries. This contribution of assets from EQR to ERP Operating
Limited Partnership shall be deemed to occur as of the completion of the merger.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

    The following discussion summarizes the material federal income tax
consequences relating to the merger of Lexford and EQR. This discussion is not
exhaustive of all possible tax consequences. For example, it does not include a
detailed discussion of any state, local or foreign tax consequences. In
addition, the following discussion is intended to address only those federal
income tax consequences

                                       37
<PAGE>
that are generally applicable to U.S. shareholders who hold the shares of
Lexford and EQR as capital assets. The discussion is not intended to address all
of the aspects of federal income taxation that may be relevant to particular
U.S. shareholders in light of their specific circumstances or to certain types
of shareholders (including insurance companies, tax-exempt entities, financial
institutions or broker-dealers, foreign corporations and persons who are not
citizens or residents of the United States) who are subject to special treatment
under the federal income tax laws.

    The statements and opinions in this discussion are based on current
provisions of the Internal Revenue Code of 1986 and its legislative history,
existing, temporary and currently proposed Treasury Regulations under the
Internal Revenue Code, existing administrative rulings and practices of the IRS
and judicial decisions. We cannot assure you that legislative, judicial or
administrative changes will not affect the accuracy of any statements in this
joint proxy statement/prospectus with respect to transactions entered into or
contemplated prior to the effective date of such changes. In addition, EQR and
Lexford have not requested and do not plan to request any rulings from the IRS
concerning the tax treatment of the merger. Accordingly, no assurance can be
given that the statements set forth in this section (which do not bind the IRS
or the courts) will not be challenged by the IRS or sustained by the courts if
so challenged.

    THIS DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING.
EACH EQR AND LEXFORD SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE APPLICATION OF SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF
THE MERGER, INCLUDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES
THAT MAY BE APPLICABLE TO SUCH HOLDER.

    TAX CONSEQUENCES OF THE MERGER

    In the opinion of each of Rudnick & Wolfe and Willkie Farr & Gallagher,
based on factual representations of EQR and Lexford and assumptions set forth in
the opinions, the merger will be treated for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code, and EQR and Lexford will each be a party to such reorganization within the
meaning of Section 368(b) of the Internal Revenue Code. Shareholders of EQR and
Lexford should be aware that such opinions of counsel are not binding on the
IRS, and no assurance can be given that such opinions of counsel will not be
challenged by the IRS or sustained by a court if so challenged.

    If the merger qualifies as a reorganization under Section 368(a) of the
Internal Revenue Code, an EQR shareholder will not recognize any gain or loss as
a result of the merger. Similarly, a Lexford shareholder who receives solely EQR
shares in exchange for Lexford shares will not recognize any gain or loss on the
exchange. However, if a Lexford shareholder receives EQR shares and cash in lieu
of a fractional EQR share, such Lexford shareholder will recognize taxable gain
or loss in an amount equal to the difference between such cash and the tax basis
allocated to such Lexford shareholder's fractional EQR share. Such gain or loss
will constitute capital gain or loss if the Lexford shares were held as a
capital asset and long-term capital gain or loss if held for more than 12
months.

    A Lexford shareholder will have an aggregate tax basis in the EQR shares
received in the merger equal to his aggregate tax basis in the Lexford shares
(reduced by the amount of any tax basis allocable to a fractional share interest
for which cash is received) that were exchanged for those EQR shares. A Lexford
shareholder's holding period for EQR shares received in the merger will include
his holding period for the Lexford shares that were exchanged for those EQR
shares if the Lexford shares are held as a capital asset by the Lexford
shareholder at the effective time of the merger. If a Lexford shareholder holds
multiple blocks of Lexford shares that have different holding periods and/or
different tax bases, the EQR shares received for each block of Lexford shares
will have a separate tax basis and holding period that is determined by
reference to the specific tax basis and holding period of the specific Lexford
shares exchanged for those EQR shares.

                                       38
<PAGE>
    No gain or loss will be recognized by EQR or Lexford as a result of the
merger so long as the merger qualifies as a reorganization under Section 368(a)
of the Internal Revenue Code.

    CONSEQUENCES OF THE MERGER ON EQR'S ABILITY TO USE LEXFORD'S NET OPERATING
LOSSES.  At the end of its taxable year ending as of the effective time of the
merger, Lexford is expected to have net operating losses for federal income tax
purposes of approximately $72.95 million. Section 382 of the Internal Revenue
Code limits a corporation's use of its net operating losses if a corporation has
a cumulative change in ownership of greater than 50% within a three-year period.
Lexford will undergo such an ownership change as a result of the merger, and
consequently EQR will be subject to the limitation with respect to the use of
Lexford's net operating losses under Section 382 of the Internal Revenue Code.
Because EQR is a REIT under the Internal Revenue Code and is not generally
subject to federal income tax, EQR does not believe the limitation on EQR's
ability to use the net operating losses will have a material adverse impact on
EQR's operations.

    EARNINGS AND PROFITS OF EQR.  The current earnings and profits of EQR for
its taxable year ending December 31, 1999 will include all earnings and profits
of EQR for the period beginning on January 1, 1999 up to the effective date, and
all earnings and profits of EQR, as the surviving entity in the merger, for the
period beginning on the effective date and ending on December 31, 1999. No
dividends declared and paid by Lexford prior to the effective time will
constitute distributions by EQR for federal income tax purposes, rather such
dividends will constitute dividends of Lexford and will be reported to Lexford
shareholders as dividends of Lexford.

    EFFECT OF THE MERGER ON EQR'S QUALIFICATION AS A REIT

    GENERAL.  The REIT provisions of the Internal Revenue Code (Section 856
through Section 860) are highly technical and complex. The following sets forth
the material aspects of the provisions of the Internal Revenue Code that govern
the federal income tax treatment of a REIT. This summary is based on current
provisions of the Internal Revenue Code and its legislative history, existing,
temporary and currently proposed Treasury Regulations under the Internal Revenue
Code, existing administrative rulings and practices of the IRS and judicial
decisions. We cannot assure you that legislative, judicial or administrative
changes will not affect the accuracy of any statements in this joint proxy
statement/ prospectus with respect to transactions entered into or contemplated
prior to the effective date of such changes. In addition, EQR and Lexford have
not requested and do not plan to request any rulings from the IRS concerning
EQR's or Lexford's eligibility to be taxed as a REIT.

    Lexford intends to file an election to be taxed as a REIT under the Internal
Revenue Code commencing with its taxable year ended December 31, 1998. In the
opinion of Willkie Farr & Gallagher, Lexford's special counsel, commencing with
Lexford's taxable year ended December 31, 1998, Lexford has been organized and
operated in conformity with the requirements for qualification as a REIT under
the Internal Revenue Code, and Lexford's proposed method of operations will
enable it to continue to meet the requirements for qualification and taxation as
a REIT under the Internal Revenue Code until the effective time of the merger.

    EQR's immediate predecessor elected to be taxed as a REIT under the Internal
Revenue Code commencing with its taxable year ended December 31, 1992. In the
opinion of Rudnick & Wolfe, EQR's special counsel, commencing with EQR's taxable
year ended December 31, 1992, EQR has been organized and operated in conformity
with the requirements for qualification as a REIT under the Internal Revenue
Code, and EQR's proposed method of operation, taking into account the merger,
will enable it to continue to meet the requirements for qualification and
taxation as a REIT under the Internal Revenue Code.

                                       39
<PAGE>
    It must be emphasized that the opinion of each of Rudnick & Wolfe and
Willkie Farr & Gallagher is based on, and conditioned upon, assumptions,
representations and covenants as to factual matters, including assumptions,
representations and covenants made by EQR and Lexford regarding the nature of
EQR's properties and Lexford's properties and EQR's and Lexford's previous
conduct of and EQR's future conduct of their respective businesses in accordance
with the REIT requirements that are described in this joint proxy
statement/prospectus. EQR's and Lexford's qualification and taxation as a REIT
depends on their ability to meet, through actual annual operating results,
requirements relating to asset ownership, distribution levels, and diversity of
stock ownership, and the various qualification tests imposed by the Internal
Revenue Code discussed in this joint proxy statement/prospectus. After the
merger, counsel will not review EQR's compliance with those tests on a
continuing basis, accordingly, no assurance can be given that EQR's operating
results for any particular taxable year will satisfy the requirements for
taxation as a REIT under the Internal Revenue Code. An opinion of counsel is not
binding on the IRS or the courts and there can be no assurance that the IRS will
not challenge EQR's or Lexford's eligibility for taxation as a REIT.

    Provided that an entity qualifies for taxation as a REIT, it generally will
not be subject to federal corporate income tax on its net income that is
currently distributed to its shareholders. This treatment substantially
eliminates the "double taxation" at the corporate and shareholder levels that
generally results from investment in a subchapter C corporation.

    However, a REIT will be subject to tax in the circumstances discussed below.
If a REIT should fail to satisfy either the 75% or the 95% gross income test, as
discussed below, and nonetheless maintains its qualification as a REIT because
certain other requirements are met, it will be subject to a 100% tax on the
greater of the amount by which it fails the 75% or the 95% gross income test,
multiplied by a fraction intended to reflect its profitability. In addition, if
a REIT should fail to distribute during each calendar year at least the sum of
(A) 85% of its REIT ordinary income for such year, (B) 95% of its REIT capital
gain net income for such year, and (C) any undistributed taxable income from
prior years, a REIT would be subject to a 4% excise tax on the excess of such
required distribution over the amounts actually distributed. Notwithstanding the
foregoing, a REIT may elect to retain, rather than distribute, all or a portion
of its net long-term capital gains and pay the tax on the gains at normal
corporate capital gains tax rates. In such a case, a REIT may elect to have its
shareholders include their proportionate share of the undistributed long-term
capital gains in income and receive a credit for their share of the tax paid by
the REIT. For purposes of the 4% excise tax described above, any retained
amounts would be treated as having been distributed. A REIT may also be subject
to the corporate "alternative minimum tax," as well as tax in certain situations
and on certain transactions not presently contemplated.

    PROHIBITED TRANSACTIONS.  A REIT will be subject to a 100% tax on net income
derived from "prohibited transactions." "Prohibited transactions" are, in
general, sales or other dispositions of property held as inventory or primarily
for sale to customers in the ordinary course of business. Both EQR and Lexford
have in the past, and EQR intends in the future to hold its properties for
investment with a view toward long-term appreciation, to engage in the business
of acquiring, developing, owning and operating the properties, and to make such
occasional sales of properties as are consistent with these investment
objectives. Based upon such investment objectives, EQR and Lexford believe that
the amount of income from prohibited transactions, if any, will not be material.

    BUILT-IN GAINS.  In general, if a REIT acquires assets from a subchapter C
corporation in a transaction in which the adjusted tax basis of the asset in the
hands of the REIT is determined by reference to the adjusted basis of the asset
in the hands of subchapter C corporation, then the subchapter C corporation is
required to recognize any net built-in gain (the amount by which the fair market
value of the assets transferred to the REIT exceeds the corporation's adjusted
tax basis in such assets) that would have been realized if the subchapter C
corporation had liquidated immediately prior to the transfer. Similarly, if a
subchapter C corporation files an election to be taxed as a REIT, then

the subchapter C corporation would be required to recognize any net built-in
gain that would have been realized if the subchapter C corporation had
liquidated on the last day of the last taxable year that it was a subchapter C
corporation.

    However, pursuant to IRS Notice 88-19, a REIT may elect, in lieu of the
treatment described above, to make itself subject to the highest regular
corporate tax rate on the net built-in gain if it disposes of these assets
during the ten-year period following their acquisition (or in the case of a
subchapter C corporation electing REIT status, the ten-year period beginning on
the first date of the taxable year for which REIT status was elected). If this
election is made, a REIT will not be subject to the corporate level tax if the
assets are disposed of after the ten year period. Lexford intends to file on its
1998 tax return an election to be taxed as a REIT and to make the election under
IRS Notice 88-19. Therefore, after completion of the merger, EQR will be taxed
at the highest regular corporate rate on such net built-in gain if and to the
extent that any assets of Lexford that have a net built-in gain are sold within
the ten-year period beginning January 1, 1998.

    In order to qualify as a REIT, both EQR and Lexford must meet, among others,
the following requirements:

    SHARE OWNERSHIP TEST.  Shares of beneficial interest of a REIT must be held
by a minimum of 100 persons for at least 335 days of a taxable year that is 12
months, or during a proportionate part of a taxable year of less than 12 months.
In addition, no more than 50% in value of the shares of beneficial interest of a
REIT may be owned, directly or indirectly (by applying certain constructive
ownership rules) by five or fewer individuals during the last half of each
taxable year. The tests described in the two preceding sentences need not be
satisfied until the second taxable year for which a REIT election is made. EQR
and Lexford believe that they have each satisfied both of these tests, and EQR
believes it will continue to do so. In order to help comply with the second of
these tests, both EQR and Lexford have placed certain restrictions on the
transfer of their respective common and preferred shares that are intended to
prevent further concentration of share ownership.

    To monitor their compliance with the share ownership requirements, REITs are
required to maintain records regarding the actual ownership of their shares. To
do so, REITs must demand written statements each year from specified record
holders of their stock in which the record holders are to disclose the
beneficial owners of the shares, which are the persons required to include in
gross income the REIT dividends. A list of those persons failing or refusing to
comply with this demand must be maintained as part of the REIT's records. A
shareholder who fails or refuses to comply with this demand must submit a
statement with its tax return disclosing the actual ownership of the shares and
certain other information. EQR and Lexford believe that they have complied with
this requirement and EQR believes it will continue to do so in the future.

    OWNERSHIP OF PARTNERSHIP INTERESTS.  In the case of a REIT that is a partner
in a partnership, Treasury Regulations provide that the REIT is deemed to own
its proportionate share of the partnership's assets and to earn its
proportionate share of the partnership's income. In addition, the assets and
gross income of the partnership retain the same character in the hands of the
REIT for purposes of the gross income and asset tests applicable to REITs as
described below.

    INCOME TESTS.  In order to maintain its qualification as a REIT, at least
75% of a REIT's gross income, excluding gross income from "prohibited
transactions," for each taxable year must be derived directly or indirectly from
investments relating to real property or mortgages on real property or from
permitted temporary investments. In addition, at least 95% of a REIT's gross
income, excluding gross income from prohibited transactions, for each taxable
year must be derived from income qualifying under the 75% gross income test, and
from dividends, interest and gain from the sale or disposition of stock or
securities. Both EQR and Lexford believe they have satisfied these requirements
and EQR believes it will continue to do so in the future.

                                       41
<PAGE>
    Rents received by a REIT will qualify as "rents from real property" in
satisfying the gross income requirements described above only if several
conditions are met. First, the amount of rent must not be based in whole or in
part on the income or profits of any person. However, the amount of rent may be
based on a fixed percentage or percentages of receipts or sales. Second, if rent
attributable to personal property leased in connection with a lease of real
property is greater than 15% of the total rent received under the lease, then
the portion of rent attributable to the personal property will not qualify as
"rents from real property." Third, for rents received to qualify as "rents from
real property," the REIT generally must not operate or manage the property or
furnish or render services, which are not "usual and customary" services, to the
tenants of such property, other than through an "independent contractor" from
which the REIT derives no revenue. However, a REIT (or its affiliates) is
permitted to directly perform services that are "usually or customarily
rendered" in connection with the rental of space for occupancy only and are not
otherwise considered rendered to the occupant of the property. In addition, a
REIT (or its affiliates) may provide non-customary services to tenants of its
properties without disqualifying all of the rent from the property if the
payment for the services does not exceed 1% of the total gross income from the
property. For purposes of this test, the income received from any non-customary
services is deemed to be at least 150% of the direct cost of providing the
services. The Internal Revenue Code also provides that rents received from a
tenant will not qualify as "rents from real property" if the REIT, or an owner
of 10% or more of the REIT, directly or constructively, owns 10% or more of the
tenant.

    EQR and Lexford believe that the services they provide with respect to their
properties has not caused EQR or Lexford to fail to satisfy the 75% and 95%
gross income tests.

    If a REIT fails to satisfy one or both of the 75% or 95% gross income tests
for any taxable year, it may nevertheless qualify as a REIT for that year if the
REIT's failure to meet such tests was due to reasonable cause and not due to
willful neglect, the REIT attaches a schedule of the sources of its income to
its return, and any incorrect information on the schedule was not due to fraud
with intent to evade tax. It is not possible, however, to state whether in all
circumstances a REIT would be entitled to the benefit of these relief
provisions.

    ASSET TESTS.  At the close of each quarter of its taxable year, a REIT must
also satisfy three tests relating to the nature of its assets. First, at least
75% of the value of its total assets must be represented by real estate assets
including real property, interests in mortgages on real properties and shares in
other REITs, stock or debt instruments held for not more than one year purchased
with the proceeds of a stock offering or long-term (at least five years) debt
offering, cash, cash items and U.S. government securities. Second, not more than
25% of a REIT's total assets may be represented by securities other than those
in the 75% asset class. Third, of the investments included in the 25% asset
class, the value of any one issuer's securities owned by a REIT may not exceed
5% of the value of the REIT's total assets, and a REIT may not own more than 10%
of any one issuer's outstanding voting securities. EQR and Lexford believe that
they have complied with the asset test requirements and EQR believes that it
will continue to do so in the future.

    EQR and Lexford own corporations that are "qualified REIT subsidiaries"
under the Internal Revenue Code. Qualified REIT subsidiaries are corporations
that are wholly owned by a REIT or another qualified REIT subsidiary. Qualified
REIT subsidiaries are not treated as separate entities from their parent REIT
for federal income tax purposes. Instead, all assets, liabilities and items of
income, deduction and credit of each qualified REIT subsidiary are treated as
assets, liabilities and items of the REIT. Each qualified REIT subsidiary
therefore will not be subject to federal corporate income taxation, although it
may be subject to state or local taxation. In addition, a REIT's ownership of
the voting stock of each qualified REIT subsidiary does not violate the general
restrictions against ownership of more than 10% of the voting securities of any
issuer or more than 5% of the value of the REIT's total assets.

                                       42
<PAGE>
    ANNUAL DISTRIBUTION REQUIREMENTS.  In order to maintain its qualification, a
REIT is generally required to distribute dividends, other than capital gain
dividends, to its shareholders each taxable year in an amount at least equal to
95% of its taxable income computed without regard to the dividends paid
deduction and net capital gain. These distributions must be made in the taxable
year to which they relate, or in the following taxable year if declared before a
REIT timely files its tax return for the prior year and if paid with or before
the first regular dividend payment after the declaration is made.

    It is possible that a REIT, from time to time, could lack sufficient cash to
meet the 95% distribution requirement, for example, due to timing differences
between (1) the actual receipt of income and actual payment of deductible
expenses and (2) the inclusion of such income and deduction of such expenses in
arriving at taxable income of the REIT. In the event that a cash short-fall
occurs, in order to meet the 95% distribution requirement, the REIT may find it
necessary to arrange for short-term, or possibly long-term, borrowings or to pay
dividends in the form of taxable distributions of property.

    A REIT may be able to rectify a failure to meet the distribution requirement
for a year by paying "deficiency dividends" to shareholders in a later year,
which may be included in the REIT's deduction for dividends paid for the earlier
year. Thus, a REIT may be able to avoid being taxed on amounts distributed as
deficiency dividends; however, the REIT will be required to pay interest based
on the amount of any deduction taken for deficiency dividends.

    EQR and Lexford believe that they have made, and EQR intends to make in the
future, timely distributions sufficient to satisfy all annual distribution
requirements. In this regard, the limited partnership agreement of ERP Operating
Limited Partnership authorizes its general partner to take any steps as may be
necessary to cause ERP Operating Limited Partnership to distribute to its
partners amounts sufficient to permit EQR to meet these distribution
requirements. It is possible, however, that EQR may experience the timing
differences discussed above, thus requiring EQR to arrange for short-term or
long-term borrowing to meet the distribution requirements.

    FAILURE TO QUALIFY.  If a REIT fails to qualify for taxation as a REIT in
any taxable year, and the relief provisions do not apply, the REIT will be
subject to tax, including any applicable alternative minimum tax, on its taxable
income at regular corporate rates (maximum effective rate of 35%). Distributions
to shareholders in any year in which the REIT fails to qualify as a REIT will
not be deductible nor will they be required to be made. Upon failing to qualify
as a REIT, to the extent of the REIT's current and accumulated earnings and
profits, all distributions to shareholders will be taxable as ordinary income
and, subject to limitations of the Internal Revenue Code, corporate distributees
may be eligible for the dividends received deduction. Unless entitled to relief
under specific statutory provisions, the REIT will also be disqualified from
taxation as a REIT for the four taxable years following the year during which
qualification was lost. It is not possible to state whether in all circumstances
EQR or Lexford would be entitled to any statutory relief.

    TAX ASPECTS OF A REIT'S INVESTMENT IN PARTNERSHIPS

    In general, partnerships are "pass-through" entities that are not subject to
federal income tax. Rather, partners are allocated their proportionate shares of
the items of income, gain, loss, deduction and credit of a partnership, and are
potentially subject to tax thereon, without regard to whether the partners
receive a distribution from the partnership. EQR and Lexford believe that each
of the partnerships in which they own an interest is classified as a partnership
or a disregarded entity as opposed to an association taxable as a corporation
for federal income tax purposes.

    PUBLICLY TRADED PARTNERSHIPS.  Publicly traded partnerships will be taxed as
corporations under Section 7704 of the Internal Revenue Code, unless a certain
percentage of their income consists of "qualifying income." A partnership is "a
publicly traded partnership" if interests in such partnership are either traded
on an established securities market or are "readily tradable on a secondary
market or

                                       43
<PAGE>
the substantial equivalent thereof." Under the Treasury Regulations promulgated
under Section 7704 of the Internal Revenue Code, interests in a partnership are
readily tradable on a secondary market or substantial equivalent thereof if,
"taking into account all of the facts and circumstances, the partners are
readily able to buy, sell, or exchange their partnership interests in a manner
that is comparable, economically, to trading on an established securities
market." EQR and Lexford believe that none of the partnerships in which they own
an interest are publicly traded partnerships.

    Even if a partnership is classified as a publicly traded partnership, it may
avoid taxation as a corporation under the Internal Revenue Code if at least 90%
of its gross income for each taxable year consists of passive income, including
interest, dividends, real property rents, and gains from the sale or other
disposition of real property. These are predominantly the types of income that
ERP Operating Limited Partnership expects to earn. Thus, if ERP Operating
Limited Partnership was classified as a publicly traded partnership, but
satisfied the 90% gross income test, it would not be taxed as a corporation.

    If ERP Operating Limited Partnership at any time were considered a publicly
traded partnership and did not satisfy the 90% qualifying income test, or if any
of the partnerships EQR or Lexford owns were treated as an association, then
such entity would be taxed as a corporation for federal income tax purposes
which would jeopardize EQR's or Lexford's status as a REIT for federal income
tax purposes. In such a situation, the character of EQR's or Lexford's assets
and items of gross income would change, which could cause them to fail to
satisfy the asset tests and the income tests, and in turn could prevent EQR or
Lexford from qualifying as a REIT.

    TAX ALLOCATIONS WITH RESPECT TO THE PROPERTIES.  The Internal Revenue Code
and Treasury Regulations provide that income, gain, loss and deduction
attributable to appreciated or depreciated property that is contributed to a
partnership in exchange for an interest in the partnership must be allocated in
a manner so that the contributing partner is charged with, or benefits from,
respectively, the unrealized gain or unrealized loss associated with the
property at the time of the contribution. The amount of unrealized gain or
unrealized loss is generally equal to the difference between the fair market
value of contributed property at the time of contribution, and the adjusted tax
basis of the property at the time of contribution (a "Book-Tax Difference").
These allocations are solely for income tax purposes and do not affect the book
capital accounts or other economic or legal arrangements among the partners.
Where a partner contributes cash to a partnership that holds appreciated
property, the Treasury Regulations provide for similar allocations to the other
partners.

    The ERP Operating Limited Partnership agreement requires these allocations
to be made in a manner consistent with the Internal Revenue Code and Treasury
Regulations. As a result, limited partners of ERP Operating Limited Partnership
will be allocated lower amounts of depreciation deductions for tax purposes and
increased taxable income and gain on sale by these partnerships of contributed
assets with Book-Tax Differences. These allocations will tend to eliminate the
Book-Tax Difference associated with such assets over the lives of these
partnerships. However, these allocation rules, as applied by EQR, will not
always entirely rectify the Book-Tax Difference on an annual basis or with
respect to a specific taxable transaction such as a sale. The carryover basis of
the contributed assets in the hands of these partnerships will cause EQR to be
allocated lower depreciation and other deductions, and possibly greater amounts
of taxable income in the event of a sale of such contributed assets in excess of
the economic or book income allocated to it as a result of such sale. This may
cause EQR to recognize taxable income in excess of cash proceeds, which might
adversely affect EQR's ability to comply with the REIT distribution
requirements.

    SALE OF PROPERTY.  Generally, any gain realized by ERP Operating Limited
Partnership on the sale of real property, if the property is held for more than
one year, will be long-term capital gain although a portion of this gain may be
treated as depreciation or cost recovery recapture.

                                       44

    INFORMATION REPORTING AND BACKUP WITHHOLDING

    EQR will report to its domestic shareholders and the IRS (to the extent
required) the amount of distributions paid during each calendar year and the
amount of tax withheld, if any. Under the backup withholding rules under the
Internal Revenue Code, a shareholder may be subject to backup withholding at a
rate of 31% with respect to distributions paid unless the holder (1) is a
corporation or comes within other exempt categories and, when required,
demonstrates this fact or (2) provides a taxpayer identification number,
certifies as to no loss of exemption from backup withholding, and otherwise
complies with the applicable requirements of the backup withholding rules. A
shareholder who does not provide EQR with his or her correct taxpayer
identification number may also be subject to penalties imposed by the IRS. Any
amount paid as backup withholding will be creditable against the shareholder's
income tax liability. In addition, EQR may be required to withhold a portion of
capital gain distributions to any non-domestic shareholders who fail to certify
their foreign status. The IRS has issued final Treasury Regulations regarding
the backup withholding rules as applied to non-domestic shareholders. These
final Treasury Regulations alter the current system of backup withholding
compliance and will be effective for payments made after December 31, 2000.

    POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING TAX CONSEQUENCES

    The rules dealing with federal income taxation are constantly under review,
by persons involved in the legislative process and by the IRS and the United
States Department of the Treasury. Changes to the federal laws and their
interpretation could adversely affect an investment in EQR. It cannot be
predicted whether, when, in what forms, or with what effective dates, the tax
laws applicable to EQR or an investment in its securities will be changed.

    FINANCIAL FREEDOM ACT OF 1999.  The Financial Freedom Act of 1999 (the
"Act"), currently before the House Committee on Ways and Means, contains several
proposed changes to the REIT provisions of the Internal Revenue Code. One
proposal would amend the tax rules relating to the composition of a REIT's
assets. Under current law, a REIT is precluded from owning more than 10% of the
outstanding voting securities of any one issuer, other than a wholly owned
subsidiary or another REIT. Under the proposal, a REIT would remain subject to
the current restriction and would be precluded from owning more than 10% of the
value of all classes of stock of any covered issuer. This proposed change would
not apply to certain debt instruments held by a REIT, securities held by a REIT
on July 12, 1999 or, in general, securities acquired by a REIT in certain
tax-free transactions subsequent to July 12, 1999. However, the proposed change
would apply to securities, other than debt instruments described in the
preceding sentence, held directly or indirectly by a REIT as of the first day
subsequent to July 12, 1999 on which the issuer of such securities engages in a
substantial new line of business or acquires any substantial asset.

    The Act also contains an exception to both the 10% asset test described
above and a second REIT asset test which precludes any one issuer's securities
owned by a REIT to exceed 5% of the value of a REIT's total assets. This
exception would allow a REIT to form and own up to 100% of the outstanding
securities of a taxable REIT subsidiary which could provide a limited amount of
services to a REIT's tenants and others. The Act would change the current law by
allowing a REIT (1) to have voting control of subsidiaries that provide services
to third parties, and (2) to provide "non-customary" services to a REIT's
tenants through a taxable REIT subsidiary without disqualifying the rents the
REIT receives from those tenants. The Act would permit a REIT to combine and
convert existing corporate subsidiaries into taxable REIT subsidiaries tax-free
for a limited period of time.

    The Act would apply the limitations on deductibility of interest provided
under the "earnings stripping" rules of Section 163(j) of the Internal Revenue
Code to interest paid or accrued by a taxable REIT subsidiary with respect to
debt owed to its parent REIT.

                                       45
<PAGE>
    Furthermore, under the Act, amounts paid by a taxable REIT subsidiary to its
parent REIT for the rental of real property would be considered "rents from real
property" under the Internal Revenue Code. The provisions of the Act described
in this paragraph and in the two preceding paragraphs would apply to taxable
years beginning after December 31, 2000.

    In addition to the above described provisions regarding REITs, the Act
proposes to lower the maximum capital gain rates applicable to individuals from
20% to 15% with respect to gains derived from sales of capital assets occurring
on or after July 1, 1999. The tax rate for Section 1250 depreciation recapture
would be lowered from 25% to 20% for assets sold on or after July 1, 1999.
Furthermore, the corporate capital gain rate would be decreased from 35% to 34%
for taxable years beginning after December 31, 1999, and would be reduced by one
percentage point each year after the year 2000, until a 25% rate is reached for
the taxable year beginning after December 31, 2008.

    CLINTON ADMINISTRATION PROPOSAL.  On February 1, 1999 the Clinton
Administration announced its budget proposal for fiscal year 2000 which
contained provisions relating to REITs similar to that contained in the Act. The
Clinton Administration proposal regarding taxable REIT subsidiaries differs from
that contained in the Act in that it would permit REITs to form two kinds of
taxable REIT subsidiaries: (1) "qualified independent contractor subsidiaries"
which could perform services for tenants and other customers that a REIT
currently cannot perform and (2) "qualified business subsidiaries" which could
undertake third-party management and development activities as well as other
non-real estate related activities. Under the Clinton Administration proposal,
no more than 15% of the value of a REIT's total assets could consist of these
taxable REIT subsidiaries and no more than 5% of the value of a REIT's total
assets could consist of qualified independent contractor subsidiaries. In
addition, a taxable REIT subsidiary would not be entitled to deduct any interest
on debt funded directly or indirectly by the REIT.

    It is presently unknown whether the Act, the Clinton Administration
proposal, or any other proposed legislation regarding REIT's or federal taxation
will be enacted.

    STATE AND LOCAL TAXES

    EQR and its shareholders may be subject to state and local tax in various
states and localities, including those states and localities in which it or they
transact business, own property, or reside. The tax treatment in these
jurisdictions may differ from the federal income tax treatment described above.
Consequently, prospective shareholders should consult their tax advisors
regarding the effect of state and local tax laws upon an investment in EQR
securities.

                      INTERESTS OF LEXFORD MANAGEMENT AND
                             TRUSTEES IN THE MERGER

    In considering whether to approve the merger, shareholders should be aware
that executive officers, other officers and trustees of Lexford have interests
that arise in connection with the merger that are in addition to the interests
of Lexford shareholders generally. These interests arise under existing
agreements, previously approved compensation awards, previously approved
employee benefit programs and the merger agreement.

OFFICER RETENTION AND SEVERANCE PROGRAM

    On May 10, 1999, the Lexford Board of Trustees adopted the Lexford Officer
Retention and Severance Program for the executive officers and other officers of
Lexford. The Lexford Board of Trustees amended the Officer Retention and
Severance Program on June 23, 1999. The Officer Retention and Severance Program
is designed to compensate individuals for work associated with the transition of
operations pursuant to the merger agreement and to provide severance payments to
individuals whose employment is terminated as a result of the merger.

    The Lexford executive officers and key employees may receive lump sum cash
severance payments and transition bonuses of up to $4,423,145 in the aggregate.
The lump sum severance payments would be made upon termination of employment.
Lump sum transition bonuses will be paid at various times for work in
conjunction with the completion of the merger. Each of the following executive
officers, who are referred to in this joint proxy statement/prospectus as the
"named executive officers," will receive the following lump sum transition
payments under the Officer Retention and Severance Program and the following
lump sum severance payments if his or her employment is terminated as a result
of the merger or within a specified period after the completion of the merger,
except for each of Messrs. Bartling and Thompson, who will receive such payments
whether or not his employment is terminated:

    To receive a severance payment or a transition bonus, each individual is
required to execute and deliver an agreement and release releasing Lexford and
EQR from any and all liabilities relating to that individual's employment.

LEXFORD OPTIONS

    Pursuant to Lexford's 1992 Incentive Equity Plan, Lexford has granted
options to acquire Lexford common shares to its officers, trustees and key
employees. Lexford options generally vest and become exercisable over a period
of two to five years and, for grants made prior to 1999, become fully vested and
exercisable upon the occurrence of a change in control. Lexford options granted
in 1999 become fully vested and exercisable if an employee's employment is
terminated by a successor other than as a result of "gross misconduct" or if the
employee resigns for "good reason" within one year following a change in
control. In addition, upon a change in control, if authorized by a committee of
the Lexford Board of Trustees designated under the plan, vested Lexford options
may be exchanged for a cash payment equal to the difference between the fair
market value of the shares subject to the option

                                       47
<PAGE>
surrendered and the option exercise price. The committee also has the authority
under the plan to substitute other equitable consideration in exchange for the
surrender of Lexford options.

    Pursuant to the terms of the merger agreement, at least ten days prior to
the completion of the merger, EQR may designate the specific Lexford options
that will be canceled as of the completion of the merger. Individuals holding a
Lexford option scheduled for cancellation will receive a lump sum cash payment
equal to the positive difference, if any, between the applicable exercise price
set forth in the option and closing price of a Lexford common share multiplied
by the number of shares subject to the option. The "closing price" means the
average closing price of a Lexford common share reported in the NYSE composite
transactions by The Wall Street Journal, Midwest Edition, for ten trading days
ending on the third trading day immediately prior to the closing date of the
merger. A trading day means a day Lexford common shares are traded on the NYSE.
As of the date of this joint proxy statement/prospectus, EQR has not identified
the Lexford options to be canceled, but currently expects that the options held
by all Lexford trustees and personnel terminating their employment upon
completion of the merger will receive cash for their options.

    Each Lexford option which remains unexercised and is not canceled as of the
completion of the merger will be converted into an option to purchase 0.463 of
an EQR common share for each Lexford common share subject to the Lexford option.
The new exercise price per share shall be calculated by dividing the exercise
price per share of the Lexford option by 0.463 and the option shall otherwise
continue as an option to purchase EQR common shares, to be exercisable pursuant
to its terms.

    After considering the number of options to purchase Lexford common shares
that will vest as a result of the merger, the exercise price per share of the
Lexford options vested as a result of the merger and assuming a fair market
value per EQR common share of $44.00, it is presently anticipated that the value
of the installments of options vesting as a result of the merger is as follows:

TAX RECOGNITION PAYMENTS

    On May 13, 1999 and June 23, 1999 the Lexford Board of Trustees approved the
payment of tax recognition payments to Messrs. Bartling and Thompson and each of
the non-employee trustees. The tax recognition payments were intended to
partially offset the adverse tax impact resulting from the receipt of lump sum
distributions to be made under the Lexford Executive Deferred Compensation

VESTING OF RESTRICTED SHARES

    Under the terms of the existing restricted share award agreements between
Lexford and Lexford's named executive officers and trustees, respectively, all
restrictions on Lexford common shares previously granted to Lexford named
executive officers and trustees will lapse as a result of a change in control.
In addition, individual named executive officers and trustees will receive the
following number of additional shares and cash, as a result of the lapse of
these restrictions:

    Under the terms of the merger agreement, executive officers, trustees, and
former trustees, may continue to defer receipt of the Lexford common shares and
cash whether vesting occurs prior to or as a result of the merger to the extent
these amounts are currently held for their benefit under the Lexford Executive
Deferred Compensation Rabbi Trust for a period of six months following the
closing date. Deferrals may be made by participating in the EQR Supplemental
Retirement Savings Plan and Trust which will be merged with the Lexford
Executive Deferred Compensation Rabbi Trust in connection with the completion of
the merger.

INDEMNIFICATION OF OFFICERS AND TRUSTEES

    EQR shall indemnify each person who is or has been an officer or trustee of
Lexford or any subsidiary to the extent currently indemnified by Lexford as
provided by Maryland law, the Lexford Declaration of Trust, the Lexford Bylaws,
and the other Lexford employee benefit plans for actions on or prior to the
completion of the merger, including all transactions contemplated by the merger
agreement. EQR has agreed to provide "run off" trustees and officers liability
insurance for six years after the completion of the merger with a coverage
amount and other terms comparable to Lexford's current trustees and officers
liability insurance with respect to their service as trustees and officers of
Lexford prior to the completion of the merger. The Lexford Declaration of Trust
limits the liability of Lexford trustees, officers and employees for monetary
damages to the maximum extent permitted by Maryland law and provides for the
indemnification of trustees, officers and employees.

FINANCIAL ADVISOR FEES

    Lexford will pay Brown Gibbons Lang, as financial advisor to Lexford, a fee

Based on the closing price of EQR common shares on July 19, 1999, their fee
would be approximately $1.8 million. Glenn C. Pollack, a managing director of
Brown Gibbons Lang, is a trustee of Lexford.

                            MANAGEMENT AND OPERATION
                            OF EQR AFTER THE MERGER

    Upon the completion of the merger, the executive officers and trustees of
EQR will continue to serve for the balance of their unexpired terms or their
earlier death, resignation or removal. Leslie Fox, Executive Vice President and
Chief Operating Officer of Lexford, is expected to become President of the
Lexford Division of EQR following the merger. Other executive officers of
Lexford may also become officers or employees of EQR. However, as of the date of
this joint proxy statement/ prospectus, there were no understandings or
arrangements with respect to any other Lexford executive officer becoming an
officer or employee of EQR.

                  PROPOSAL TO AMEND EQR'S DECLARATION OF TRUST

    If the amendment is approved, EQR's Declaration will be amended in the
merger to provide for shareholder approval of future mergers only when required
under Maryland law. In 1997, Maryland law regarding shareholder approval of
mergers was amended to substantially conform to the rules of the NYSE. Under
Maryland law, as amended, a merger or consolidation of a Maryland REIT surviving
the merger or consolidation is required to be approved only by its board of
trustees if: (1) the merger or consolidation does not reclassify or change the
REIT's outstanding shares or otherwise amend its declaration of trust and (2)
the number of shares to be issued or delivered in the merger or consolidation is
not more than 20% of the number of its shares of the same class or series
outstanding immediately before the merger becomes effective. EQR's Declaration
of Trust as presently in effect requires all mergers or consolidations,
regardless of size, to be approved by holders of a majority of the outstanding
EQR common shares. Therefore, the amendment, if approved, will provide EQR with
added flexibility to react to acquisition opportunities, including the ability
to engage in acquisitions which may not otherwise be feasible due to the time
involved in obtaining shareholder approval. In addition, if it is approved, the
amendment will eliminate the costs relating to shareholder approval presently
required with respect to merger or consolidation transactions of limited size.
Mergers or consolidations subject to shareholder approval will continue to
require the affirmative vote of the holders of not less than a majority of the
EQR shares entitled to vote on the merger or consolidation. The text of the
amendment is attached as Exhibit A to Appendix B to this joint proxy statement/
prospectus.

    The EQR Declaration of Trust permits the Declaration to be amended in
connection with a merger approved by the EQR shareholders. Because EQR's
Declaration will be amended as part of the merger, approval of the merger would
constitute approval of the amendment. However, the EQR Board of Trustees is
requesting EQR common shareholders to approve the amendment separately. If the
amendment is not separately approved, EQR's Declaration will not be amended in
the merger.

    The amendment must be approved by the affirmative vote of the majority of
the votes cast on the matter by EQR common shareholders at the EQR special
meeting, provided a quorum is present. The

                                       50
<PAGE>
approval of the merger is not conditioned upon the approval of the amendment by
the EQR shareholders. In the event that the merger is approved by the EQR
shareholders but the amendment is not separately approved, the amendment will
not take effect.

    The Board of Trustees of EQR unanimously recommends that you vote for the
amendment.

                      COMPARISON OF RIGHTS OF SHAREHOLDERS

    Upon the completion of the merger, the shareholders of Lexford will become
shareholders of EQR. The rights of Lexford shareholders are presently governed
by Title 8 of the Corporations and Associations Article of the Annotated Code of
Maryland, the Lexford Declaration of Trust and the Lexford Bylaws. The rights of
EQR's shareholders are presently governed by Title 8, the EQR Declaration of
Trust and the EQR Bylaws. After the merger, the rights of former Lexford
shareholders will be governed by Title 8, the EQR Declaration of Trust and the
EQR Bylaws.

    The following discussion summarizes certain significant differences between
the rights of shareholders of EQR and Lexford. This summary does not purport to
be complete and is subject to and qualified in its entirety by reference to
Title 8, the EQR Declaration of Trust and Bylaws and the Lexford Declaration of
Trust and Bylaws. Rights of the shareholders of EQR and Lexford which are the
same and will remain so after the merger are not discussed.

AUTHORIZED AND ISSUED SHARES

    The Lexford Declaration of Trust authorizes the issuance of 110,000,000
shares of beneficial interest, $.01 par value per share, of which 5,000,000 are
Lexford preferred shares, 50,000,000 are Lexford common shares, 50,000,000 are
Lexford excess common shares and 5,000,000 are Lexford excess preferred shares.
As of June 30, 1999, 9,554,228 Lexford common shares, and no shares of any other
class, were issued and outstanding.

    The EQR Declaration of Trust currently authorizes the issuance of
450,000,000 shares of beneficial interest, of which 350,000,000 are EQR common
shares, par value $.01 per share, and 100,000,000 are EQR preferred shares, par
value $.01 per share, which may be issued from time to time in one or more
series. EQR has established and issued twelve series of preferred shares,
designated series A through L.

SPECIAL MEETINGS

    The Lexford Bylaws provide that special meetings of the shareholders of
Lexford may be called by the Board of Trustees. No officer, trustee or
shareholder has the authority to call a meeting of shareholders without the
express authorization of the Lexford Board of Trustees.

    The EQR Bylaws provide that the Chairman, the President or one-third of the
trustees of EQR may call a special meeting of EQR's shareholders. Also, a
special meeting may be called by the Secretary of EQR upon the written request
of EQR shareholders entitled to cast not less than a majority of all the votes
entitled to be cast at such a meeting.

BOARDS OF TRUSTEES

    The Lexford Declaration of Trust provides for a Board of Trustees consisting
of not more than 17 nor less than three trustees. The Lexford Declaration of
Trust states that the trustees of Lexford shall be divided into three classes
with the term of each class expiring at the annual meeting of Lexford
shareholders in the third year following their election. The number of trustees
in any class shall not exceed six. The Lexford Declaration of Trust also
provides that a trustee may be removed (1) only with cause by the affirmative
vote of the holders of not less than a majority of the shares of beneficial
interest then outstanding and entitled to vote generally in the election of
trustees, or (2) with or

                                       51
<PAGE>
without cause, by the affirmative vote of a majority of the remaining members of
the Board of Trustees. The Lexford Declaration of Trust does not define cause.

    The EQR Declaration of Trust provides for a Board of Trustees consisting of
not more than 15 nor less than two trustees. The EQR Declaration of Trust states
that the trustees of EQR shall be divided into three classes, as nearly as equal
in number as possible, with the term of each class of trustees expiring at the
annual meeting of EQR shareholders in the third year following their election.
The EQR Declaration of Trust also provides that a trustee may be removed only
with cause, by the vote of the holders of not less than two-thirds of the shares
of beneficial interest then outstanding and entitled to vote in the election of
trustees. The EQR Declaration of Trust defines "cause" as (1) material theft,
fraud or embezzlement or active and deliberate dishonesty by a trustee, (2)
habitual neglect of duty by a trustee having a material and adverse significance
to EQR, or (3) the conviction of a trustee of a felony or of any crime involving
moral turpitude.

AMENDMENT TO DECLARATION OF TRUST AND BYLAWS

    The Lexford Declaration of Trust provides that the Lexford Board of Trustees
may, by a two-thirds vote, amend the Lexford Declaration of Trust from time to
time without any action by the shareholders in order to qualify as a REIT under
the Internal Revenue Code or under Title 8. The Lexford Declaration of Trust
provides that the power to adopt, alter and repeal the Bylaws of Lexford is
vested exclusively in the Lexford Board of Trustees.

    The EQR Declaration of Trust provides that the EQR Board of Trustees may, by
a two-thirds vote, amend the EQR Declaration of Trust from time to time in order
to enable EQR to qualify as a REIT under the Internal Revenue Code and under
Title 8. Except as set forth in the previous sentence, in the terms of the EQR
preferred shares or with regard to amendments effectuated pursuant to a merger,
the EQR Declaration of Trust may be amended only by the affirmative vote of the
holders of not less than two-thirds of the shares of beneficial interest then
outstanding and entitled to vote on the matter. The EQR Declaration also
provides that the EQR Board of Trustees, without any action by the shareholders,
shall have and may exercise, on behalf of EQR, without limitation, the power to
terminate the status of EQR as a REIT under the Internal Revenue Code. The EQR
Bylaws provide that the EQR Board of Trustees shall have the exclusive power to
adopt, alter or repeal any provision of the EQR Bylaws or make new EQR Bylaws.

MERGERS, CONSOLIDATIONS, AND SALE OF SUBSTANTIALLY ALL ASSETS

    The Lexford Declaration of Trust provides that a merger will not take effect
until it has been approved by the affirmative vote of the holders of a majority
of the outstanding shares entitled to vote on the matter.

    The Lexford Declaration of Trust provides that the Lexford Board of Trustees
has the power to sell all or substantially all of the assets of Lexford. If a
sale of all or substantially all of the assets of Lexford is made outside of the
ordinary course of business and for consideration other than money or the
assumption of debt, then that sale must be approved by the affirmative vote of
the holders of a majority of the outstanding Lexford shares entitled to vote on
that matter.

    The EQR Declaration of Trust provides that the affirmative vote of the
holders of a majority of the EQR common shares is required to approve a merger,
consolidation, or the sale of all or substantially all, of the assets of EQR. If
adopted, the amendment would amend the EQR Declaration of Trust in the merger to
provide for shareholder approval of a merger or consolidation only when required
under Maryland law.

RESTRICTIONS ON THE OWNERSHIP, TRANSFER OR ISSUANCE OF SHARES

    The Lexford Declaration of Trust, subject to certain exceptions, provides
that no holder may own, or be deemed to own by virtue of the attribution
provisions of the Internal Revenue Code, with respect to the Lexford common
shares, more than 9.2% of the outstanding common equity shares of Lexford and,
with respect to any class or series of preferred shares, more than 9.8% of the
outstanding preferred shares of such class or series (the "Lexford Ownership
Limit").

    Any transfer of Lexford shares that would (1) create a direct or indirect
ownership of shares of beneficial interest, in any class, in excess of the
Lexford Ownership Limit, (2) result in the shares of beneficial interest being
owned by fewer than 100 persons, (3) result in Lexford being "closely held"
within the meaning of Section 856(h) of the Internal Revenue Code, (4) result in
Lexford violating the securities laws or Maryland regulations, or (5) result in
the failure of Lexford to qualify as a REIT within the meaning of the Internal
Revenue Code or Title 8, will be void from the inception, and the intended
transferee will acquire no rights to the Lexford shares causing the violation.
The foregoing restrictions on transferability and ownership will not apply if
the Lexford Board of Trustees determines that it is no longer in the best
interests of Lexford to attempt to qualify, or to continue to qualify, as a
REIT.

    Any shares of Lexford, the transfer of which would result in a person owning
shares of any class or series in excess of the Lexford Ownership Limit with
respect to that class or series, will automatically be converted into excess
shares of the same class or series and be transferred to a charitable trust, the
trustee of which shall be unaffiliated with Lexford.

    Any holder who acquires directly, indirectly or constructively a beneficial
interest in shares of Lexford in excess of the Lexford Ownership Limit shall
immediately give written notice to Lexford of the acquisition and shall provide
Lexford any other information that Lexford may request in order to determine the
effect, if any, of the acquisition or attempted acquisition on Lexford's status
as a REIT.

    The Lexford excess shares held in the charitable trust shall be issued and
outstanding, but the prohibited owner shall have no rights to the shares or the
benefits from the shares except for limited rights upon dissolution or
liquidation. The shares, and any distributions or dividends paid on the shares,
shall be held for the benefit of the charitable beneficiary. As soon as
reasonably practicable, and in an orderly fashion so as not to affect in a
materially adverse manner the market price of the shares held in the charitable
trust, the trustee shall sell the shares and pay the proceeds of the sale to the
prohibited owner; provided, however, that if the price paid by the prohibited
owner is less than the proceeds received by the trustee, the prohibited owner
shall receive the lesser amount and the excess proceeds will be paid to the
charitable beneficiary.

    The EQR Declaration of Trust, subject to certain exceptions, provides that
no holder may own, or be deemed to own by virtue of the attribution provisions
of the Internal Revenue Code, more than 5% (the "EQR Ownership Limit") of the
lesser of the number of shares or value of the issued and outstanding shares of
beneficial interest of EQR. The EQR Board of Trustees, upon receipt of a ruling
from the Internal Revenue Code, an opinion of counsel or other evidence
satisfactory to the EQR Board of Trustees and upon such other conditions as the
EQR Board of Trustees may direct, may, provided that specified conditions are
met, exempt a proposed transferee from the EQR Ownership Limit. The intended
transferee must give written notice to EQR of the proposed transfer no later
than the fifteenth day prior to any transfer which, if consummated, would result
in the intended transferee owning shares in excess of the EQR Ownership Limit.

    Any transfer of EQR common shares or EQR preferred shares that would (1)
create a direct or indirect ownership of shares of beneficial interest in excess
of the EQR Ownership Limit, (2) result in the shares of beneficial interest
being owned by fewer than 100 persons, or (3) result in EQR being "closely held"
within the meaning of Section 856(h) of the Internal Revenue Code, will be void
ab

                                       53
<PAGE>
initio, and the intended transferee will acquire no rights to the shares of
beneficial interest. The foregoing restrictions on transferability and ownership
will not apply if the EQR Board of Trustees determines that it is no longer in
the best interests of EQR to attempt to qualify, or to continue to qualify, as a
REIT.

    EQR's Declaration exempts from the EQR Ownership Limit certain persons and
entities who would exceed the EQR Ownership Limit as a result of the exchange of
the units of limited partnership in ERP Operating Limited Partnership for EQR
common shares, which units were received by them at the time of EQR's formation.
These persons may also acquire additional EQR common shares through EQR's Second
Amended and Restated 1993 Share Option and Share Award Plan, but in no event
will such persons be entitled to acquire additional shares of beneficial
interest such that the five largest beneficial owners of EQR's shares of
beneficial interest hold more than 50% in number or value of the total
outstanding EQR shares.

    Any transfer of EQR common shares which would result in a person owning
shares of beneficial interest in excess of the EQR Ownership Limit or cause EQR
to become "closely held" under Section 856(h) of the Internal Revenue Code that
is not otherwise permitted as provided above will automatically be transferred
to a charitable trust, the trustee of which shall be unaffiliated with EQR.

    The EQR shares held in the charitable trust shall be issued and outstanding,
but the prohibited owner shall have no rights to the shares or the benefits from
the shares. The shares, and any distributions or dividends paid on the shares
shall be held for the benefit of the charitable beneficiary. Within 20 days
after the shares are transferred to the charitable trust, the trustee shall sell
the shares and pay the proceeds of such sale to the prohibited owner; provided,
however, that if the price paid by the prohibited owner is less than the
proceeds received by the trustee, the prohibited owner shall receive the lesser
amount.

    EQR's Declaration of Trust provides that all persons who own, directly or by
virtue of the attribution provisions of the Internal Revenue Code, more than 5%
(or a lesser percentage as provided in the rules and regulations promulgated
under the Internal Revenue Code) of the lesser of the number or value of the
outstanding shares of beneficial interest of EQR must give a written notice to
EQR by January 31 of each year. In addition, each shareholder will upon demand
be required to disclose to EQR in writing such information with respect to the
direct, indirect and constructive ownership of EQR shares as the EQR Board of
Trustees deems reasonably necessary to comply with the provisions of the
Internal Revenue Code applicable to a REIT, to comply with the requirements of
any taxing authority or governmental agency or to determine any such compliance.

STANDARD OF CONDUCT FOR TRUSTEES

    The Lexford Declaration of Trust provides that a trustee shall perform his
duties as a trustee, including his duties as a member of a committee of the
Board of Trustees, in good faith, in a manner he reasonably believes to be in
the best interest of Lexford and with the care that an ordinarily prudent person
in a like position would use under similar circumstances.

    The EQR Declaration of Trust contains no similar provision regarding the
appropriate standards for trustees. Maryland corporation law requires a director
of a Maryland corporation to perform his duties in good faith in a manner he
reasonably believes to be in the best interests of the corporation and with the
care of an ordinarily prudent person in a like position under similar
circumstances. Although EQR is a trust and not a corporation, a Maryland court
might look to these standards for corporate directors in evaluating the
performance of trustees.

                                 LEGAL MATTERS

    Certain legal matters in connection with the merger will be passed upon for
EQR by Rudnick & Wolfe, Chicago, Illinois. Errol R. Halperin, a partner of
Rudnick & Wolfe, is a trustee of EQR.

                                       54

Attorneys of Rudnick & Wolfe beneficially own less than 1% of the outstanding
EQR common shares. Certain legal matters in connection with the merger will be
passed upon for Lexford by Willkie Farr & Gallagher, New York, New York and
Benesch, Friedlander, Coplan & Aronoff LLP, Cleveland, Ohio. H. Jeffrey
Schwartz, a partner of Benesch, Friedlander, Coplan & Aronoff LLP, and a trustee
of Lexford, beneficially owns 166,256 Lexford common shares. Ballard, Spahr,
Andrews & Ingersoll, LLP Baltimore, Maryland, will pass upon certain matters of
Maryland law relating to the merger agreement and Articles of Merger under
Maryland law.

                                    EXPERTS

    Ernst & Young LLP, independent auditors, have audited the consolidated
financial statements and schedule of EQR included in EQR's Annual Report on Form
10-K for the year ended December 31, 1998; the consolidated financial statements
and schedules of Lexford included in Lexford's Annual Report on Form 10-K for
the year ended December 31, 1998 and included in the Current Report of EQR on
Form 8-K, dated June 30, 1999; and the Statements of Revenue and Certain
Expenses of certain properties acquired by EQR in 1998, appearing in the Current
Report of EQR on Form 8-K dated June 25, 1998, as set forth in their reports,
which are incorporated by reference in this joint proxy statement/prospectus and
elsewhere in the registration statement. These financial statements and
schedules are incorporated by reference in reliance on Ernst & Young LLP's
reports, given on their authority as experts in accounting and auditing.

    The consolidated financial statements of Merry Land & Investment Company,
Inc. appearing in EQR's Current Report on Form 8-K, dated July 23, 1998, were
audited by Arthur Andersen LLP, independent public accountants, as indicated in
their report with respect thereto, and are incorporated in this joint proxy
statement/prospectus in reliance upon the authority of that firm as experts in
accounting and auditing.

                                    AUDITORS

    Representatives of Ernst & Young LLP will be present at the special meetings
and will have the opportunity to make a statement to the shareholders if they
desire. In addition, the representatives of Ernst & Young LLP will be available
to respond to appropriate shareholder questions.

                          FUTURE SHAREHOLDER PROPOSALS

    Shareholder proposals intended to be presented at the 2000 Annual Meeting of
Shareholders of EQR must have been received by the Secretary of EQR not later
than November 30, 1999 for inclusion in the proxy materials for that meeting. If
any business should properly come before that meeting other than that which is
stated in the proxy materials for that meeting then, if the Secretary of EQR
does not receive notice of such matter at the executive offices of EQR between
October 31, 1999 and November 30, 1999, the persons designated in the proxy form
for that meeting will have discretionary authority to vote or refrain from
voting on any such proposal.

    Due to the contemplated completion of the merger, Lexford does not currently
expect to hold a 2000 Annual Meeting of Shareholders. However, in the event that
the merger is not completed and Lexford's annual meeting is held on its assigned
date, to be eligible for inclusion in Lexford's proxy materials for that
meeting, proposals of shareholders of Lexford must have been received by the
Secretary of Lexford no later than December 31, 1999. If any business should
properly come before that meeting other than that which is stated in the proxy
materials for that meeting then, if Lexford does not receive notice of such
matter by February 9, 2000, the persons designated in the proxy form for that
meeting will have discretionary authority to vote or refrain from voting on any
such proposal.

    The Unaudited Pro Forma Combined Balance Sheet as of March 31, 1999 gives

the merger.

does it purport to represent the future combined financial position of EQR and
Lexford. This Unaudited Pro Forma Combined Balance Sheet should be read in

           basis over the estimated useful lives of the related assets. The
           estimated useful lives of buildings and furniture, fixtures and
           equipment are 30 years and 5 years, respectively.

not have a material adverse effect on the business, properties, assets,
financial condition or results of operations of Lexford and the Lexford
Subsidiaries (as defined below) taken as a whole (a "Lexford Material Adverse
Effect"). Schedule 2.1 to the Lexford Disclosure Letter sets forth each

Disclosure Letter:

           (a) Schedule 2.2 to the Lexford Disclosure Letter sets forth:

                (i) each Subsidiary of Lexford;

                                      A-9

and security interests of any kind or nature whatsoever (collectively, "Liens"),
and all equity interests in each Lexford Subsidiary that is a partnership, joint
venture, limited liability company or trust which are owned by Lexford, by
another Lexford Subsidiary or by Lexford and another Lexford Subsidiary are
owned free and clear of all Liens. Each Lexford Subsidiary that is a corporation
is duly incorporated and validly existing under the laws of its jurisdiction of
incorporation and has the requisite corporate power and authority to carry on
its business as now being conducted, and each Lexford Subsidiary that is a
partnership, limited liability company or trust is duly organized and validly

each jurisdiction in which the nature of its business or the ownership or
leasing of its properties makes such qualification or licensing necessary, other
than in such jurisdictions where the failure to be so qualified or licensed,

Effect. True and correct copies of the Articles of Incorporation, Bylaws,
partnership agreements, joint venture and operating agreements or similar
organizational documents of each Lexford Subsidiary, as amended to the date of
this Agreement, as well as the merger agreements executed in connection with

        (c) With respect to each Syndicated Subsidiary, (i) except as set forth
in Schedule 2.2 to the Lexford Disclosure Letter, Lexford or a wholly-owned

                                      A-10
<PAGE>
note and/or loan agreement, or, in the case of advances to or receivables from
any Syndicated Subsidiary, are evidenced by true and correct written records,

terms without, to the Knowledge of Lexford, any right of set-off or

of time, or

                                      A-12

the aggregate would not (x) have a Lexford Material Adverse Effect or (y)
prevent the consummation of the transactions contemplated by this Agreement.
Except as set forth on Schedule 2.5 to the Lexford Disclosure Letter, no
consent, approval, order or authorization of, or registration, declaration or

Lexford or any Lexford Subsidiary in connection with the execution and delivery
of this Agreement by Lexford or the consummation by Lexford of the transactions
contemplated by this Agreement, except for (i) the filing with the Securities
and Exchange Commission (the "SEC") of (x) a joint proxy statement relating to

material respect or have, individually or in the aggregate, a Lexford Material
Adverse Effect.

case of unaudited statements, to normal year-end audit adjustments, any other
adjustments described therein and the fact that certain information and notes
have been condensed or omitted in accordance with the Exchange Act). Schedule
2.6 of the Lexford Disclosure Letter sets forth all Lexford Subsidiaries which
are not consolidated for accounting purposes as of the date hereof. Except for

accrued, absolute, contingent or otherwise) required by GAAP to be set forth on
a consolidated balance sheet of Lexford or in the notes thereto and which,
individually or in the aggregate, would have a Lexford Material Adverse Effect,
after taking into account any assets acquired or services provided in connection
with the incurrence of such liabilities or obligations.

issuance of securities) and there has not been (a) any material adverse change
in the business, financial condition or results of operations of Lexford and the

exchange or exercise, shares of its beneficial interest or any issuance of an
ownership interest in, any Lexford Subsidiary except as contemplated by this
Agreement, (d) any damage, destruction or loss, whether or not covered by
insurance, that has or would have a Lexford Material Adverse Effect, (e) any
change made prior to the date of this Agreement in accounting methods,

                                      A-14
<PAGE>
transactions contemplated by this Agreement, nor is there any judgment, decree,

Letter, Lexford or the Lexford Subsidiary set forth on Schedule 2.2 of the
Lexford Disclosure Letter owns fee simple title to their respective Lexford
Properties. All such properties are owned in each case free and clear of liens,
mortgages or deeds of trust, claims against title, charges which are liens,
security interests or other encumbrances on title securing monetary obligations
("Encumbrances") (except as provided below). Except as set forth in Schedule
2.2, Schedule 2.18 or Schedule 2.9 of the Lexford Disclosure Letter, no other
Person has any ownership interest in any of the Lexford Properties, and any such
ownership interest so scheduled does not materially detract from the value of,
or materially interfere with the present use of, any of the Lexford Properties
subject thereto or affected thereby. The Lexford Properties are not subject to
any rights of way, written agreements, laws, ordinances and regulations
affecting building use or occupancy, or reservations of an interest in title
(collectively, "Property Restrictions") or other Encumbrances, except for (i)
Encumbrances and Property Restrictions set forth in the Lexford Disclosure
Letter, (ii) Property Restrictions imposed or promulgated by law or any
governmental body or authority with respect to real property, including zoning
regulations, provided they do not materially adversely affect the current use of
any Lexford Property, (iii) Encumbrances and Property Restrictions disclosed on
existing title reports or existing surveys (in either case copies of which title
reports and surveys have been delivered or made available to EQR, which
Encumbrances and Property Restrictions, in any event, do not materially detract
from the value of, or materially interfere with the present use of, any of the
Lexford Properties subject thereto or affected thereby (provided that Lexford
specifically represents and warrants that any Encumbrances identified on any
existing title report as securing any Indebtedness, other than the Indebtedness
identified on Schedule 2.18 of the Lexford Disclosure Letter, has been released
of record since the date of the title report in question), (iv) real estate
taxes and assessments which constitute a lien but are not yet due and payable
and (v) mechanics', carriers', workmen's, repairmen's liens, other Encumbrances
and Property Restrictions, if any, which, individually or in the aggregate, do
not materially detract from the value of or materially interfere with the
present use of any of the Lexford Properties subject thereto or affected
thereby, and do not otherwise materially impair business operations conducted by
Lexford and the Lexford Subsidiaries. Except as provided in Schedule 2.9 of the
Lexford Disclosure Letter, no portion of any of the Lexford Properties is
located in a flood zone area "V" except for that which, individually or in the
aggregate, do not materially detract from the value of or materially interfere
with the present use of such Lexford Property subject thereto or affected
thereby. Schedule 2.9 lists each of the Lexford Properties which are under
development as of the date of this Agreement.

        (b) Except as provided in Schedule 2.9 to the Lexford Disclosure Letter,
valid policies of title insurance (each a "Lexford Title Insurance Policy") have
been issued insuring Lexford's or the applicable Lexford Subsidiary's fee simple
title to the Lexford Properties, subject only to the matters disclosed above and
on the Lexford Disclosure Letter, and such policies are, at the date hereof, in
full

                                      A-15
<PAGE>
force and effect and no claim has been made against any such policy. A true and
correct copy of each Lexford Title Insurance Policy has been previously made
available to EQR.

(i) that, any certificate, permit or license from any governmental authority
having jurisdiction over any of the Lexford Properties or any agreement,
easement or other right which is necessary to permit the lawful use and
operation of the buildings and improvements on any of the Lexford Properties or
which is necessary to permit the lawful use and operation of all driveways,
roads and other means of egress and ingress to and from any of the Lexford
Properties has not been obtained and is not in full force and effect, or of any
pending threat of modification or cancellation of any of same; (ii) of any
written notice of any violation of any federal, state or municipal law,
ordinance, order, regulation or requirement materially and adversely affecting
any of the Lexford Properties issued by any governmental authority; (iii) of any
material structural defects relating to any Lexford Property which costs more
than $50,000 to repair; (iv) of any Lexford Property whose building systems are

(vi) of any current renovation or uninsured restoration underway to any Lexford
Property the cost of which exceeds $50,000; or (vii) of items referred to in
Section 2.9(c)(iii)-(vi) which aggregate for Lexford and the Lexford
Subsidiaries more than $2,500,000.

        (d) Except as set forth in Schedule 2.9 to the Lexford Disclosure
Letter, neither Lexford nor any of the Lexford Subsidiaries has received any
written notice to the effect that (i) any condemnation or rezoning proceedings

the Lexford Properties or by the continued maintenance, operation or use of the
parking areas.

        (e) Except as set forth in Schedule 2.9 to the Lexford Disclosure
Letter, all of the Lexford Properties are managed by Lexford or a wholly-owned
Lexford Subsidiary.

        (f) The Rent Roll for the Lexford Properties as of June 1, 1999 has been
previously delivered or made available to EQR, and is complete and correct in
all material respects as of the date thereof.

        (g) Except as set forth in Schedule 2.9 to the Lexford Disclosure
Letter, all work required to be performed, payments required to be made and
actions required to be taken prior to the date hereof pursuant to any agreement
entered into with a governmental body or authority in connection with a site
approval, zoning reclassification or other similar action relating to any
Lexford Properties (e.g., local improvement district, road improvement district,
environmental mitigation) have been performed, paid or taken, as the case may
be, other than those where, individually or in the aggregate with any other
condition or omission resulting in a breach of the representations and
warranties set forth in this Section 2.9, the failure would not have a Lexford
Material Adverse Effect, and Lexford has no Knowledge of any material work,
payments or actions that are required after the date hereof pursuant to such
agreements, except as set forth in development or operating budgets for such
Lexford Properties delivered to EQR prior to the date hereof.

        (h) Lexford and each of the Lexford Subsidiaries have good and
sufficient title to all their personal and non-real properties and assets
reflected in their books and records as being owned by them (including those
reflected in the consolidated balance sheet of Lexford as of December 31, 1998,
except as since sold or otherwise disposed of in the ordinary course of
business), free and clear of all liens and encumbrances, except such
Encumbrances reflected on Schedule 2.18 or Schedule 2.9 to the Lexford
Disclosure Letter or on the consolidated balance sheet of Lexford as of December
31, 1998,

                                      A-16
<PAGE>
and the notes thereto, and except for liens for current taxes not yet due and
payable, and liens or encumbrances which are normal to the business of Lexford
and the Lexford Subsidiaries and are not, in the aggregate, material in relation
to the assets of Lexford on a consolidated basis and except also for such
imperfections of title, easement and encumbrances, if any, as do not materially
interfere with the present use of the properties subject thereto or affected
thereby, or otherwise materially impair the consolidated business operations of
Lexford.

        (i) Except as set forth in Schedule 2.9 to the Lexford Disclosure
Letter, no Lexford Property is currently under development or subject to any
agreement with respect to development, and neither Lexford nor any Lexford
Subsidiary shall enter into any such agreements between the date hereof and the
Effective Time without the prior written approval of EQR.

complete copy of the environmental reports by third-party consulting firms

limitation, all final versions of environmental investigations and testing or
laboratory analysis made by or on behalf of Lexford or any of the Lexford
Subsidiaries) with respect to the Lexford Properties in the possession of
Lexford or any Lexford Subsidiary. With respect to each Lexford Property, except

have not received and do not reasonably expect to receive any notice of
potential responsibility, letter of inquiry or notice of alleged liability under
any Environmental Law from any Person regarding such Lexford Property or the
business conducted thereon, PROVIDED, HOWEVER, that with respect to any Lexford
Property covered by an Environmental Report, the representation contained in
this Section 2.10 covers only that period following the date of such
Environmental Report. For the purposes of this Section 2.10 only, "Lexford
Properties" shall be deemed to include all property formerly owned, operated or

<PAGE>
with respect to which such a governmental authority otherwise requires
environmental investigation, monitoring, reporting, or remediation; including,
but not limited to,

        (a) all substances, wastes, pollutants, contaminants and materials

Disclosure Letter is a list of all arrangements, agreements and contracts
entered into by Lexford or any of the Lexford Subsidiaries under which
continuing obligations exist with (a) any consultant (other than a consultant
entitled to receive less than $10,000 from Lexford or any Lexford Subsidiary,
PROVIDED, HOWEVER, that if the total amount owed to consultants by Lexford and
the Lexford Subsidiaries exceeds $100,000, all such agreements shall be set
forth in Schedule 2.11), (b) any person who is an officer, trustee, director or
Affiliate (as defined below) of Lexford or any of the Lexford Subsidiaries, any
member of the "immediate family" (as such term is defined in Item 404 of
Regulation S-K promulgated under the Securities Act) of any of the foregoing or
any entity of which any of the foregoing is an Affiliate or (c) any person who
acquired Lexford Shares in a private placement within three years preceding the
date hereof, except those of a type available to Lexford employees generally. To
the extent in writing, such documents, copies of all of which have previously
been delivered or made available to EQR, are listed in Schedule 2.11 to the
Lexford Disclosure Letter. As used in this Agreement, the term "Affiliate" shall
have the same meaning as such term is defined in Rule 405 promulgated under the
Securities Act.

    2.12  EMPLOYEE BENEFITS.  As used herein, the term "Employee Plan" includes
any pension, retirement, savings, disability, medical, dental, health, life,
death benefit, group insurance, profit sharing, deferred compensation, stock
option, stock loan, bonus, incentive, vacation pay, tuition reimbursement,
severance pay, or other employee benefit plan, trust, agreement, contract,
arrangement, policy or commitment (including, without limitation, any pension
plan, as defined in Section 3(2) of the Employee Retirement Income Security Act
of 1974, as amended and the rules and regulations promulgated thereunder
("ERISA") ("Pension Plan"), and any welfare plan as defined in Section 3(1) of
ERISA ("Welfare Plan")), whether any of the foregoing is funded, insured or
self-funded, written or oral, (i) sponsored or maintained by Lexford or Lexford
Subsidiaries (each a "Controlled Group Member") and covering any Controlled
Group Member's active or former employees (or their beneficiaries), (ii) to
which any Controlled Group Member is a party or by which any Controlled Group
Member (or any of the rights, properties or assets thereof) is bound or (iii)
with respect to which any current Controlled Group Member may otherwise have any
material liability (whether or not

                                      A-18
<PAGE>
such Controlled Group Member still maintains such Employee Plan). Each Employee
Plan is listed on Schedule 2.12. With respect to the Employee Plans:

        (a) Except as disclosed in the Lexford SEC Documents or in Schedule 2.12
    to the Lexford Disclosure Letter, no Controlled Group Member has any
    continuing liability under any Welfare Plan which provides for continuing
    benefits or coverage for any participant or any beneficiary of a participant
    after such participant's termination of employment, except as may be
    required by section 4980B of the Code or Section 601 (ET SEQ.) of ERISA, or
    under any applicable state law, and at the expense of the participant or the
    beneficiary of the participant.

        (b) Each Employee Plan complies in all material respects with the
    applicable requirements of ERISA and any other applicable law governing such
    Employee Plan, and each Employee Plan has at all times been properly
    administered in all material respects in accordance with all such
    requirements of law, and in accordance with its terms and the terms of any
    applicable collective bargaining agreement to the extent consistent with all
    such requirements of law. Each Pension Plan which is intended to be
    qualified is qualified under Section 401(a) of the Code, has received a
    favorable determination letter from the Internal Revenue Service (the "IRS")
    stating that such Plan meets the requirements of Section 401(a) of the Code
    and that the trust associated with such Plan is tax exempt under Section
    501(a) of the Code and no event has occurred which would jeopardize the
    qualified status of any such plan or the tax exempt status of any such trust
    under Sections 401(a) and Section 501(a) of the Code, respectively. No
    lawsuits, claims (other than routine claims for benefits) or complaints to,
    or by, any person or governmental entity have been filed or are pending,
    Lexford has received no notice of such a lawsuit, claim or complaint and, to
    the Knowledge of Lexford, there is no fact or contemplated event which would
    be expected to give rise to any such lawsuit, claim (other than routine
    claims for benefits) or complaint with respect to any Employee Plan. Without
    limiting the foregoing, except as disclosed on Schedule 2.12 to the Lexford
    Disclosure Letter, the following are true with respect to each Employee
    Plan:

           (i) except for those not yet required to be filed or distributed, all
       Controlled Group Members have filed or caused to be filed every material
       return, report, statement, notice, declaration and other document
       required by any law or governmental agency, federal, state and local
       (including, without limitation, the IRS and the Department of Labor) with
       respect to each such Employee Plan, each of such filings has been
       complete and accurate in all material respects and no Controlled Group
       Member has incurred any material liability in connection with such
       filings;

           (ii) except for those not yet required to be filed or distributed,
       all Controlled Group Members have delivered or caused to be delivered to
       every participant, beneficiary and other party entitled to such material,
       all material plan descriptions, returns, reports, schedules, notices,
       statements and similar materials, including, without limitation, summary
       plan descriptions and summary annual reports, as are required under Title
       I of ERISA, the Code, or both, and no Controlled Group Member has
       incurred any material liability in connection with such deliveries;

           (iii) all contributions and payments with respect to Employee Plans
       that are required to be made by a Controlled Group Member with respect to
       periods ending on or before the Closing Date (including periods from the
       first day of the current plan or policy year to the Closing Date) have
       been, or will be, made or accrued before the Closing Date in accordance
       with the appropriate plan document, actuarial report, collective
       bargaining agreements or insurance contracts or arrangements or as
       otherwise required by ERISA or the Code;

           (iv) with respect to each such Employee Plan, to the extent
       applicable, Lexford has delivered to EQR true and complete copies of (A)
       current plan documents, or any and all other documents that establish the
       existence of the current plan, trust, arrangement, contract,

                                      A-19
<PAGE>
       policy or commitment and all amendments thereto, (B) the most recent
       determination letter, if any, received from the IRS, (C) the three most
       recent Form 5500 Annual Report (and all schedules and reports relating
       thereto) and actuarial reports and (D) all related trust agreements,
       insurance contract or other funding agreements that implement each such
       Employee Plan.

        (c) With respect to each Employee Plan, there has not occurred, and no
    person or entity is contractually bound to enter into, any "prohibited
    transaction" within the meaning of Section 4975(c) of the Code or Section
    406 of ERISA, which transaction is not exempt under Section 4975(d) of the
    Code or Section 408 of ERISA.

        (d) Except as disclosed in Schedule 2.12A, no Controlled Group Member
    has maintained or been obligated to contribute to any Employee Plan subject
    to Code Section 412 or Title IV of ERISA. With respect to each Employee Plan
    set forth on Schedule 2.12A, Lexford represents that each such Employee Plan
    has been completely terminated in accordance with all Code and ERISA
    requirements for a "standard termination" (as defined in 4041(b) of ERISA),
    as applicable on the termination date.

        (e) Except as set forth in Schedule 2.12 to the Lexford Disclosure
    Letter, with respect to each pension plan maintained by any Controlled Group
    Member, such Plans provide the Plan Sponsor the authority to amend or
    terminate the plan at any time, subject to applicable requirements of ERISA
    and the Code.

        (f) Lexford has no obligation to make payments to any individual to
    offset, in whole or in part, any federal or state income taxes, including
    taxes imposed pursuant to the provisions of Code Sections 280G or 4999, and
    the consummation of the transactions contemplated by this Agreement will not
    result in any excise tax withholding.

    2.13  EMPLOYEE MATTERS.  Schedule 2.13 of the Lexford Disclosure Letter
lists the employee handbooks of Lexford and each of the Lexford Subsidiaries
currently in effect. A copy of each such employee handbook has previously been
made available to EQR. Except as set forth in Schedule 2.13 of the Lexford
Disclosure Letter, such handbooks fairly and accurately summarize all material
employee policies, vacation policies and payroll practices of Lexford and the
Lexford Subsidiaries. Neither Lexford nor any of the Lexford Subsidiaries is a
party to, or bound by, any collective bargaining agreement, contract or other
agreement or understanding with a labor union or other labor organization, nor
has Lexford or any of the Lexford Subsidiaries agreed that any unit of their
employees is appropriate for collective bargaining. No union or other labor
organization has been certified as bargaining representative for any of
Lexford's employees. To the Knowledge of Lexford there are no organizational
efforts with respect to the formation of a collective bargaining unit presently
being made or threatened involving employees of Lexford or any of the Lexford
Subsidiaries.

    2.14  TAXES.

        (a) Each of Lexford and the Lexford Subsidiaries has 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 Lexford has paid on its behalf) all Taxes (as defined
below) shown or reflected on such returns and reports as required to be paid by
it except (i) as set forth in Schedule 2.14 to the Lexford Disclosure Letter, or
(ii) real estate taxes that are being contested in good faith by appropriate
proceedings and for which Lexford or the applicable Lexford Subsidiary shall
have set aside on its books adequate reserves. The most recent audited financial
statements contained in the Lexford SEC Documents reflect an adequate reserve
for all material Taxes payable or accrued by Lexford and the Lexford
Subsidiaries for all taxable periods and portions thereof through the date of
such financial statements. Since the Lexford Financial Statement Date, Lexford
has incurred no liability for taxes under Sections 857(b), 860(c) or 4981 of the
Code, including, without limitation, any tax

                                      A-20
<PAGE>
arising from a prohibited transaction described in Section 857(b)(6) of the
Code, and neither Lexford nor any Lexford Subsidiary has incurred any liability
for taxes other than in the ordinary course of business. No deficiencies for any
Taxes have been proposed, asserted or assessed pursuant to a "30-day letter" or
notice of deficiency sent by the IRS, or, to the Knowledge of Lexford, except as
set forth in Schedule 2.14 of the Lexford Disclosure Letter, otherwise proposed,
asserted or assessed against Lexford or any of the Lexford Subsidiaries. No
waivers of the time to assess any such Taxes have been executed by Lexford or
any Lexford Subsidiary and, to the Knowledge of Lexford, no requests for such
waivers are pending. As used in this Agreement, "Taxes" shall include all
federal, state, local and foreign income, property, sales, franchise,
employment, excise and other taxes, tariffs or governmental charges of any
nature whatsoever, together with penalties, interest or additions to Tax with
respect thereto.

        (b) Lexford (i) has been subject to taxation as a real estate investment
trust (a "REIT") within the meaning of Section 856 of the Code commencing with
the taxable year beginning January 1, 1998, and has satisfied all requirements
to qualify as a REIT for such year, (ii) has operated, and intends to continue
to operate, in such a manner as to qualify as a REIT until the Effective Time
and (iii) has not taken or omitted to take any action which would reasonably be
expected to (A) result in any rents paid by the tenants of the Properties to be
excluded from the definition of "rents from real property" under Section
856(d)(2)(C) of the Code, or (B) otherwise result in a challenge to its status
as a REIT, and no such challenge is pending or, to Lexford's Knowledge,
threatened. Each Lexford Subsidiary which is a partnership, joint venture or
limited liability company (i) has been since its formation and continues to be
treated for federal income tax purposes as a partnership and not as a
corporation or an association taxable as a corporation or ignored as a separate
entity, as the case may be, and (ii) has not since its formation owned any
assets (including, without limitation, securities) that would cause Lexford to
violate Section 856(c)(4) of the Code. Each Lexford Subsidiary which is a
corporation or treated as an association taxable as a corporation has been since
the date of its formation or January 1, 1998 (whichever is later) a qualified
REIT subsidiary under Section 856(i) of the Code.

    2.15  NO PAYMENTS TO EMPLOYEES, OFFICERS, TRUSTEES OR DIRECTORS.  Set forth
in Schedule 2.3, Schedule 2.15 and Schedule 2.15A of the Lexford Disclosure
Letter is a true and complete list of all cash and non-cash payments, rights to
property or other contract rights which may become payable, accelerated or
vested to or in each current or former employee, officer, trustee or director of
Lexford or any Lexford Subsidiary as a result of the Merger. Except as described
in Schedule 2.3, Schedule 2.7, Schedule 2.15 or Schedule 2.15A to the Lexford
Disclosure Letter, or as otherwise provided for in this Agreement, there is no
employment or severance contract, or other agreement requiring payments,
cancellation of indebtedness or other obligation to be made on a change of
control or otherwise as a result of the consummation of any of the transactions
contemplated by this Agreement, with respect to any current or former employee,
officer, trustee or director of Lexford or any Lexford Subsidiary.

    2.16  BROKERS; SCHEDULE OF FEES AND EXPENSES.  Except as disclosed in
Schedule 2.16 to the Lexford Disclosure Letter, no broker, investment banker,
financial advisor or other person, other than Morgan Stanley & Co. Incorporated
and Brown, Gibbons, Lang & Company, L.P., the fees and expenses of which have
previously been disclosed to EQR, is entitled to any broker's, finder's,
financial advisor's or other similar fee or commission in connection with the
transactions contemplated hereby based upon arrangements made by or on behalf of
Lexford or any Lexford Subsidiary. A true and correct copy of the engagement
letter for Morgan Stanley & Co. Incorporated; Brown, Gibbons, Lang & Company,
L.P. and each person referred to on Schedule 2.16 has been delivered to EQR
prior to the date hereof.

    2.17  COMPLIANCE WITH LAWS.  Except as disclosed in the Lexford SEC
Documents or in Schedule 2.6 or Schedule 2.17 to the Lexford Disclosure Letter,
neither Lexford nor any of the Lexford Subsidiaries has violated or failed to
comply with any statute, law, ordinance, regulation, rule,

                                      A-21
<PAGE>
judgment, decree or order of any Governmental Entity applicable to its business,
properties, operations or the Consolidation, except to the extent that such
violation or failure would not have a Lexford Material Adverse Effect.

    2.18  CONTRACTS; DEBT INSTRUMENTS.

        (a) To the Knowledge of Lexford, except as disclosed in the Lexford SEC
Documents or in Schedule 2.18 to the Lexford Disclosure Letter, there is no
contract or agreement that purports to limit in any material respect the names
under or the geographic location in which Lexford or any Lexford Subsidiary may
conduct its business. Neither Lexford nor any Lexford Subsidiary has received a
written notice that Lexford or any Lexford Subsidiary is in violation of or in
default under (nor to the Knowledge of Lexford 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 material loan or credit agreement, note,
bond, mortgage, indenture, lease, permit, concession, franchise, license or any
other material contract, agreement, arrangement or understanding, to which it is
a party or by which it or any of its properties or assets is bound, except as
set forth in Schedule 2.18 to the Lexford Disclosure Letter, nor to the
Knowledge of Lexford does such a violation or default exist, except as set forth
in Schedule 2.18 to the Lexford Disclosure Letter, or to the extent that such
violation or default, individually or in the aggregate, would not have a Lexford
Material Adverse Effect.

        (b) Except for any of the following expressly identified in Lexford SEC
Documents, Schedule 2.18 to the Lexford Disclosure Letter sets forth a list of
each loan or credit agreement, note, bond, mortgage, indenture and any other
agreement and instrument pursuant to which any Indebtedness of Lexford or any
Lexford Subsidiary is outstanding or may be incurred (collectively, the "Debt
Documents"), as well as, with respect to the Indebtedness evidenced by each Debt
Document as of May 31, 1999, the outstanding principal balance, the maturity
date, the applicable interest rate (including the method or formula for
calculating any interest that is not a fixed percentage of the principal
balance) and the amount of or the method or formula for calculating any Equity
Participation (as defined herein). For purposes of this Section 2.18,
"Indebtedness" shall mean (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 interest rate cap, swap, collar or
similar transaction or currency hedging transactions (valued at the termination
value thereof), (v) obligations to pay any equity kicker or other participation
in the operating cash flow, gross revenue or other income from the real property
or other asset of Lexford or any Lexford Subsidiary or in the gross, net or
excess sale, financing, refinancing or other capital proceeds from any such
property or other asset (whether or not in connection with any other
Indebtedness)(each an "Equity Participation") and (vi) guarantees of any such
indebtedness of any other person. Lexford hereby represents and warrants that
each item of Indebtedness may be assumed by EQR without cost or penalty, except
as set forth in Schedule 2.18 to the Lexford Disclosure Letter, and without the
consent of or requirement to obtain the approval or confirmation as to any
matter from the holder of any such Indebtedness or any other person. For
purposes of this Section 2.18, "assumed by EQR" shall mean that, immediately or
after the giving of notice or the passage of time (or both), such Indebtedness
will not, either automatically or upon the exercise of any right or option of
the holder of such Indebtedness or any other person, be accelerated or become
due and payable in whole or in part as a result of the consummation of the
transactions contemplated by this Agreement (including, without limitation, the
Merger).

        (c) To the extent not set forth in response to the requirements of
Section 2.18(b), Schedule 2.18 to the Lexford Disclosure Letter sets forth each
interest rate cap, interest rate collar, interest rate swap, currency hedging
transaction, and any other agreement relating to a similar transaction to which
Lexford or any Lexford Subsidiary is a party or an obligor with respect thereto.

        (d) Except as set forth in Schedule 2.18 to the Lexford Disclosure
Letter, neither Lexford nor any of the Lexford Subsidiaries is party to any
agreement which would restrict any of them from prepaying any of their
Indebtedness without penalty or premium at any time or which requires any of
them to maintain any amount of Indebtedness with respect to any of the Lexford
Properties.

        (e) Neither Lexford nor any of the Lexford Subsidiaries is a party to
any agreement relating to the management of any of the Lexford Properties by a
party other than Lexford or any wholly-owned Lexford Subsidiary (a "Third
Party"), except the agreements described in Schedule 2.18 to the Lexford
Disclosure Letter (the "Third Party Management Agreements"). A true and complete
copy of each Third Party Management Agreement has previously been furnished to
EQR.

        (f) Neither Lexford nor any of the Lexford Subsidiaries is a party to
any agreement pursuant to which Lexford or any Lexford Subsidiary manages any
real properties for any Third Party, except for the agreements described in

Agreements"). A true and complete copy of each Outside Management Agreement has
previously been made available to EQR.

obligation in excess of $125,000. True and correct copies of such agreements
have previously been delivered or made available to EQR.

        (h) Schedule 2.18 to the Lexford Disclosure Letter lists all agreements
entered into by Lexford or any of the Lexford Subsidiaries providing for the
sale of, or option to sell, any Lexford Properties or the purchase of, or option
to purchase, any real estate which are currently in effect.

        (i) Except as set forth in Schedule 2.18 to the Lexford Disclosure
Letter, neither Lexford nor any Lexford Subsidiary has any continuing
contractual liability (i) for indemnification or otherwise under any agreement
relating to the sale of real estate previously owned, whether directly or
indirectly, by Lexford or any Lexford Subsidiary, except for standard
indemnification provisions entered into in the normal course of business, (ii)
to pay any additional purchase price for any of the Lexford Properties, or (iii)
to make any reprorations or adjustments to prorations that may previously have
been made with respect to any property currently or formerly owned by Lexford.

        (j) Neither Lexford nor any Lexford Subsidiary has entered into or is
subject, directly or indirectly, to any "Tax Protection Agreements." As used

Partnership or any other Lexford Subsidiary that is treated as a partnership for
federal income tax purposes, and (B) that (i) prohibits or restricts in any
manner the disposition of any assets of Lexford or any Lexford Subsidiary,
(including, without limitation, requiring Lexford or any Lexford Subsidiary to
indemnify any person for any tax liabilities resulting from any such
disposition), (ii) requires that Lexford or any Lexford Subsidiary maintain, or
put in place, or replace, indebtedness, whether or not secured by one or more of
the Lexford Properties, or (iii) requires that Lexford or any Lexford Subsidiary
offer to any person or entity at any time the opportunity to guarantee or
otherwise assume, directly or indirectly, the risk of loss for federal income
tax purposes for indebtedness or other liabilities of Lexford or any Lexford
Subsidiary.

        (k) Except (i) as set forth in Schedule 2.18 to the Lexford Disclosure
Letter and (ii) for certain promissory notes ("Notes") entered into between
Lexford and certain officers and trustees of Lexford pursuant to which Lexford
is obligated, as of the date hereof, to advance a total of $80,268.96 to such
officers and trustees, there are no material outstanding contractual obligations
of Lexford or

                                      A-23
<PAGE>
any Lexford Subsidiary to make any investment in the form of a loan, capital

conducted does not and will not infringe in any way any patent, patent right,
license, trademark, trademark right, trade name, trade name right, service mark,
or copyright of any third party that, individually or in the aggregate, could
have a Lexford Material Adverse Effect. To Lexford's Knowledge, there are no
infringements of any proprietary rights owned by or licensed by or to Lexford or
any Lexford Subsidiary that individually or in the aggregate could have a

such amounts and against such risks and losses as are customary for companies
conducting the business as conducted by Lexford and the Lexford Subsidiaries
during such time period. Except as set forth on Schedule 2.25 to the Lexford

    Except as set forth in the letter of even date herewith signed by the
President or an Executive Vice President of EQR and delivered to Lexford prior

    3.1  ORGANIZATION, STANDING AND POWER OF EQR.  EQR is a real estate
investment trust duly organized and validly existing under the laws of Maryland
and has the requisite trust power and authority to carry on its business as now
being conducted. EQR is duly qualified or licensed to do business as a foreign
trust and is in good standing in each jurisdiction in which the nature of its
business or the ownership or leasing of its properties makes such qualification
or licensing necessary, other than in such jurisdictions where the failure to be
so qualified or licensed, individually or in the aggregate, would not have a
material adverse effect on the business, properties, assets, financial condition
or results of operations of EQR and the Subsidiaries of EQR ("EQR Subsidiaries")
taken as a whole ("EQR Material Adverse Effect"). EQR has delivered to Lexford
complete and correct copies of the EQR Declaration and EQR Bylaws, in each case
as amended or supplemented to the date of this Agreement.

    3.2  CAPITAL STRUCTURE.

        (a) Exhibit "B" attached hereto sets forth the authorized and issued
shares of beneficial interest of EQR as of May 31, 1999. Except as set forth in
Exhibit "B"attached hereto, as of May 31, 1999, there were no outstanding

arrangements or undertakings of any kind to which EQR or any EQR Subsidiary is a
party or by which such entity is bound, obligating EQR or any EQR Subsidiary to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock, voting securities, or other ownership interests of EQR
or any EQR Subsidiary or obligating EQR or any EQR Subsidiary to issue, grant,
extend or enter into any such security, option, warrant, call, right,

set forth in Exhibit "B" attached hereto or as required under the ERP Operating
Partnership Agreement (as defined in Section 3.3 hereof), as of May 31, 1999,
there are no outstanding contractual obligations of EQR or any EQR Subsidiary to
repurchase, redeem or otherwise acquire any shares of beneficial interest of EQR
or any capital stock, voting securities or other ownership interests in any EQR
Subsidiary or make any material investment (in the form of a loan, capital
contribution or otherwise) in any person (other than a EQR Subsidiary). EQR has
a sufficient number of authorized but unissued EQR Common Shares to issue to the
shareholders of Lexford pursuant to the terms of this Agreement.

        (b) All outstanding shares of beneficial interest of EQR are duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights, except that the shareholders of EQR may be subject to further
assessment with respect to certain claims for tort, contract, taxes, statutory
liability and otherwise in some jurisdictions to the extent such claims are not
satisfied by EQR. There are no bonds, debentures, notes or other indebtedness of
EQR having the right to vote (or convertible into, or exchangeable for,
securities having the right to vote) on any matters on which shareholders of EQR
may vote.

        (c) EQR owns all of its partnership interests in ERP Operating Limited
Partnership, an Illinois limited partnership of which EQR is the sole general
partner ("ERP Operating Partnership") free and clear of all Liens.

        (d) All of the EQR Common Shares issuable in accordance with this
Agreement in exchange for Lexford Common Shares will be, when so issued, duly
authorized, validly issued, fully paid and non-assessable and shall be delivered
free and clear of all liens, claims, charges and encumbrances of any kind or
nature whatsoever, including any preemptive rights of any holder of shares of
beneficial interest of EQR.

    3.3  ORGANIZATION, STANDING AND POWER OF ERP OPERATING PARTNERSHIP.  ERP
Operating Partnership is a limited partnership duly organized and validly
existing under the laws of Illinois and has the requisite power and authority to
carry on its business as now being conducted. ERP Operating Partnership is duly
qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to be so qualified or licensed,
individually or in the aggregate, would not have a EQR Material Adverse Effect.
EQR has delivered to Lexford a complete and correct copy of ERP Operating
Partnership's Fifth Amended and Restated Agreement of Limited Partnership, as
amended or supplemented to the date of this Agreement (the "ERP Operating
Partnership Agreement").

    3.4  CAPITAL STRUCTURE OF ERP OPERATING PARTNERSHIP.  Exhibit "B" attached

Shareholder Approvals, the "Shareholder Approvals"), to consummate the
transactions contemplated by this Agreement to which EQR is a party. The
execution and delivery of this Agreement by EQR and the consummation by EQR of
the transactions contemplated by this Agreement to which EQR is a party have

<PAGE>
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium or other similar laws relating to creditors' rights and general
principles of equity.

        (b) Except as set forth in Schedule 3.5 to the EQR Disclosure Letter,
the execution and delivery of this Agreement by EQR do not, and the consummation
of the transactions contemplated by this Agreement by EQR and compliance by EQR
with the provisions of this Agreement will 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 material obligation or to loss of a material benefit under, or result in the
creation of any Lien upon any of the properties or assets of EQR or any EQR
Subsidiary under, (i) the EQR Declaration or EQR Bylaws or the comparable
charter or organizational documents or partnership or similar agreement (as the
case may be) of any other EQR Subsidiary, each as amended or supplemented to the

governmental filings and other matters referred to in the following sentence,
any Laws applicable to EQR or any EQR Subsidiary or their respective properties
or assets, other than, in the case of clause (ii) or (iii), any such conflicts,
violations, defaults, rights, loss or Liens that individually or in the
aggregate would not (x) have an EQR Material Adverse Effect or (y) prevent the
consummation of the transactions contemplated by this Agreement. No consent,
approval, order or authorization of, or registration, declaration or filing
with, any Governmental Entity is required by or with respect to EQR or any EQR
Subsidiary in connection with the execution and delivery of this Agreement or
the consummation by EQR of any of the transactions contemplated by this
Agreement, except for (i) the filing with the SEC of (x) the Proxy Statement,
(y) the Registration Statement and (z) such reports under Section 13(a) of the
Exchange Act as may be required in connection with this Agreement and the
transactions contemplated by this Agreement, (ii) the acceptance for record of
the Articles of Merger by the Department, (iii) such filings as may be required
in connection with the payment of any transfer and gains taxes and (iv) such
other consents, approvals, orders, authorizations, registrations, declarations

(B) as may be required under (x) federal, state or local environmental laws or
(y) the securities laws of the State of Maryland or (C) which, if not obtained
or made, would not prevent or delay in any material respect the consummation of
any of the transactions contemplated by this Agreement or otherwise prevent EQR
from performing its obligations under this Agreement in any material respect or
have, individually or in the aggregate, an EQR Material Adverse Effect.

        (c) For purposes of determining compliance with the Hart-Scott Act, EQR
confirms that the conduct of its business does not require a filing under the
Hart-Scott Act in connection with the Merger.

    3.6  SEC DOCUMENTS; FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES.  EQR and
ERP Operating Partnership have filed all required reports, schedules, forms,
statements and other documents with the SEC since August 18, 1994 through the
date hereof (the "EQR SEC Documents"). All of the EQR SEC Documents (other than
preliminary material), as of their respective filing dates or as of the date of
the last amendment thereof (if amended after filing), complied in all material
respects with all applicable requirements of the Securities Act and the Exchange
Act and, in each case, the rules and regulations promulgated thereunder
applicable to such EQR SEC Documents. None of the EQR SEC Documents at the time
of filing contained any untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading, except to the extent such statements have been modified or
superseded by later EQR SEC Documents filed on a non-confidential basis prior to
the date of this Agreement. The consolidated financial statements of EQR and the
EQR Subsidiaries included in the EQR SEC Documents complied as to form in all
material

                                      A-27
<PAGE>
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto, have been prepared in accordance
with GAAP (except, in the case of unaudited statements, as permitted by the
applicable rules and regulations of the SEC) applied on a consistent basis
during the periods involved (except as may be indicated therein or in the notes
thereto) and fairly presented, in accordance with the applicable requirements of
GAAP and the applicable rules and regulations of the SEC in all material
respects, the consolidated financial position of EQR and the EQR Subsidiaries,
taken as a whole, as of the dates thereof and the consolidated results of
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments, any other
adjustments described therein and the fact that certain information and notes
have been condensed or omitted in accordance with the Exchange Act). Except for
liabilities and obligations set forth in the EQR SEC Documents or in Schedule
3.6 to the EQR Disclosure Letter, neither EQR nor any EQR Subsidiary has any
liabilities or obligations of any nature (whether accrued, absolute, contingent
or otherwise) required by GAAP to be set forth on a consolidated balance sheet
of EQR or in the notes thereto and which, individually or in the aggregate,
would have an EQR Material Adverse Effect, after taking into account any assets
acquired or services provided in connection with the incurrence of such
liabilities or obligations.

    3.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in the EQR
SEC Documents or in Schedule 3.7 to the EQR Disclosure Letter, since the date of
the most recent audited financial statements included in the EQR SEC Documents
(the "EQR Financial Statement Date"), EQR and the EQR Subsidiaries have
conducted their business only in the ordinary course (taking into account prior
practices, including the acquisition of properties and issuance of securities)
and there has not been (a) any material adverse change in the business,
financial condition or results of operations of EQR and the EQR Subsidiaries
taken as a whole (a "EQR Material Adverse Change"), nor has there been any
occurrence or circumstance that with the passage of time would reasonably be
expected to result in an EQR Material Adverse Change, (b) except for regular
quarterly distributions (in the case of EQR) with customary record and payment
dates, any declaration, setting aside or payment of any dividend or other
distribution (whether in cash, stock or property) with respect to any of EQR's
shares of beneficial interest, (c) any split, combination or reclassification of
any of EQR's shares of beneficial interest, (d) any damage, destruction or loss,
whether or not covered by insurance, that has or would have an EQR Material
Adverse Effect, or (e) any change made prior to the date of this Agreement in
accounting methods, principles or practices by EQR or any EQR Subsidiary
materially affecting its assets, liabilities or business, except insofar as may
have been disclosed in the EQR SEC Documents or required by a change in GAAP.
EQR is not in default in the payment of distributions on the EQR Preferred
Shares.

    3.8  LITIGATION.  Except as disclosed in the EQR SEC Documents or in
Schedule 3.8 to the EQR Disclosure Letter, and other than personal injury and
other routine tort litigation arising from the ordinary course of operations of
EQR and the EQR Subsidiaries (a) which are covered by adequate insurance, or (b)
for which all material costs and liabilities arising therefrom are reimbursable
pursuant to common area maintenance or similar agreements, there is no suit,
action or proceeding pending or, to the Knowledge of EQR, threatened in writing
against or affecting EQR or any EQR Subsidiary that, individually or in the
aggregate, could reasonably be expected to (i) have an EQR Material Adverse
Effect, or (ii) prevent the consummation of any of the transactions contemplated
by this Agreement, nor is there any judgment, decree, injunction, rule or order
of any Governmental Entity or arbitrator outstanding against EQR or any EQR
Subsidiary having, or which could reasonably be expected to have, any such
effect.

        (a) EQR or one of the EQR Subsidiaries owns fee simple title to each of
the real properties listed in the EQR SEC Filings as owned by it (the "EQR
Properties"), except where the failure to own such title would not have an EQR
Material Adverse Effect.

                                      A-28
<PAGE>
        (b) The EQR Properties are not subject to any Encumbrances or Property
Restrictions or located in a flood zone area "V" which, individually or in the

        (c) Valid policies of title insurance have been issued insuring EQR's or
the applicable EQR Subsidiaries' fee simple title to the EQR Properties in
amounts at least equal to the purchase price thereof paid by EQR or the
applicable EQR Subsidiaries therefor, except where the failure to obtain such
title insurance would not have an EQR Material Adverse Effect.

        (d) EQR has no Knowledge (i) that it has failed to obtain a certificate,
permit or license from any governmental authority having jurisdiction over any
of the EQR Properties where such failure would have an EQR Material Adverse
Effect, or of any pending threat of modification or cancellation of any of the
same which would have an EQR Material Adverse Effect, (ii) of any written notice
of any violation of any federal, state or municipal law, ordinance, order, rule,
regulation or requirement affecting any of the EQR Properties issued by any
governmental authorities which would have an EQR Material Adverse Effect, or
(iii) of any structural defects relating to EQR Properties, EQR Properties whose
building systems are not in working order, physical damage to any EQR Property
for which there is no insurance in effect covering the cost of restoration, any
current renovation or uninsured restoration, except such structural defects,
building systems not in working order, physical damage, renovation and
restoration which, in the aggregate, would not have an EQR Material Adverse
Effect.

        (e) Neither EQR nor any of the EQR Subsidiaries has received any written
notice to the effect that (i) any condemnation or rezoning proceedings are
pending or threatened with respect to any
of the EQR Properties, or (ii) any zoning, building or similar law, code,
ordinance, order or regulation is or will be violated by the continued
maintenance, operation or use of any buildings or other improvements on any of
the EQR Properties or by the continued maintenance, operation or use of the
parking areas, other than such notices which, in the aggregate, would not have
an EQR Material Adverse Effect.

        (f) All work to be performed, payments to be made and actions to be
taken by EQR or the EQR Subsidiaries prior to the date hereof pursuant to any
agreement entered into with a governmental body or authority in connection with
a site approval, zoning reclassification or similar action relating to any EQR
Properties (e.g., Local Improvement District, Road Improvement District,
Environmental Mitigation), has been performed, paid or taken, as the case may
be, except where the failure to do so would, in the aggregate, not have an EQR
Material Adverse Effect, and EQR has no Knowledge of any planned or proposed
work, payments or actions that may be required after the date hereof pursuant to
such agreements which would have an EQR Material Adverse Effect.

    3.10  ENVIRONMENTAL MATTERS.  None of EQR, any of the EQR Subsidiaries or,
to EQR's Knowledge, any other Person has caused or permitted (a) the unlawful
presence of any Hazardous Substances on any of the EQR Properties, or (b) any
unlawful spills, releases, discharges or disposal of Hazardous Materials to have
occurred or be presently occurring on or from the EQR Properties as a result of
any construction on or operation and use of such properties, which presence or
occurrence would, individually or in the aggregate, have an EQR Material Adverse
Effect; and in connection with the construction on or operation and use of the
EQR Properties, EQR and the EQR Subsidiaries have not failed to comply in any
material respect with all applicable local, state and federal environmental
laws, regulations, ordinances and administrative and judicial orders relating to
the generation, recycling, reuse, sale, storage, handling, transport and
disposal of any Hazardous Materials, except to the extent such failure to
comply, individually or in the aggregate, would not have an EQR Material Adverse
Effect. EQR has previously delivered or made available to Lexford complete
copies of all environmental investigations and testing or analysis made by
third-party consultants with respect to the environment condition of the EQR
Properties.

    3.11  TAXES.

        (a) Each of EQR and the EQR Subsidiaries has 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 EQR has paid on its behalf) all Taxes shown on such returns and reports
as required to be paid by it except where the failure to file such tax returns
or reports and failure to pay such Taxes would not have an EQR Material Adverse
Effect. The most recent audited financial statements contained in the EQR SEC
Documents reflect an adequate reserve for all material Taxes payable by EQR and
the EQR Subsidiaries for all taxable periods and portions thereof through the
date of such financial statements. Since the EQR Financial Statement Date, EQR
has incurred no liability for taxes under Sections 857(b), 860(c) or 4981 of the
Code, including without limitation any tax arising from a prohibited transaction
described in Section 857(b)(6) of the Code, and neither EQR nor any EQR
Subsidiary has incurred any liability for taxes other than in the ordinary
course of business. No event has occurred, and no condition or circumstance
exists, which presents a material risk that any material Tax described in the
preceding sentence will be imposed upon EQR. No deficiencies for any Taxes have
been proposed, asserted or assessed pursuant to a "30-day letter" or notice of
deficiency sent by the IRS, or, to the Knowledge of EQR, otherwise proposed,
asserted or assessed against EQR or any of the EQR Subsidiaries. No waivers of
the time to assess any such Taxes have been executed by EQR or any EQR
Subsidiary and, to the Knowledge of EQR, no such waivers are pending.

        (b) EQR (i) for all taxable years commencing with 1992 through the most
recent December 31, has been subject to taxation as a REIT within the meaning of
Section 856 of the Code and has satisfied all requirements to qualify as a REIT
for such years, (ii) has operated, and intends to continue to operate, in such a
manner as to qualify as a REIT for the tax year ending December 31, 1999, and
(iii) has not taken or omitted to take any action which would reasonably be
expected to (A) result in any rents paid by tenants to the EQR Properties to be
excluded from the definition of "rents from real property" under Section
856(d)(2) of the Code, or (B) otherwise result in a challenge to its status as a
REIT, and to EQR's Knowledge, no such challenge is pending or threatened. Each
EQR Subsidiary which is a partnership, joint venture or limited liability
company has been treated since its formation and continues to be treated for
federal income tax purposes as a partnership, or ignored as a separate entity,
as the case may be, and not as a corporation or as an association taxable as a
corporation. Each corporation, trust or other entity taxable as an association
which has merged with and into EQR had been subject to taxation as a REIT at all
times since its initial election of REIT status and had satisfied all
requirements to qualify as a REIT for such years, except to the extent that a
failure to satisfy such requirements would not have a EQR Material Adverse
Effect. Each EQR Subsidiary which is a corporation or which is treated as an
association taxable as a corporation for federal income tax purposes (of which
EQR directly or indirectly owns ten percent (10%) or more of the outstanding
voting securities (as defined in Section 856(c) of the Code)) has been since the
date of its formation or since EQR's first taxable year as a REIT (whichever is
later) a qualified REIT subsidiary under Section 856(i) of the Code.

    3.12  BROKERS; SCHEDULE OF FEES AND EXPENSES.  No broker, investment banker,
financial advisor or other person is entitled to any broker's, finder's,
financial advisor's or other similar fee or commission in connection with the
transactions contemplated hereby based upon arrangements made by or on behalf of
EQR or any EQR Subsidiary.

    3.13  COMPLIANCE WITH LAWS.  Except as disclosed in the EQR SEC Documents,
neither EQR nor any of the EQR Subsidiaries has violated or failed to comply
with any statute, law, ordinance, regulation, rule, judgment, decree or order of
any Governmental Entity applicable to its business, properties or operations,
except to the extent that such violation or failure would not have an EQR
Material Adverse Effect.

                                      A-30
<PAGE>
    3.14  CONTRACTS; DEBT INSTRUMENTS.  Neither EQR nor any EQR Subsidiary has
received a written notice that EQR or any EQR Subsidiary is in violation of or
in default under (nor to the Knowledge of EQR 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 material loan or credit agreement, note,
bond, mortgage, indenture, lease, permit, concession, franchise, license or any
other material contract, agreement, arrangement or understanding, to which it is
a party or by which it or any of its properties or assets is bound, nor to the
Knowledge of EQR does such a violation or default exist, except to the extent
such violation or default, individually or in the aggregate, would not have an
EQR Material Adverse Effect, except as set forth in Schedule 3.14 to the EQR
Disclosure Letter.

    3.15  STATE TAKEOVER STATUTES.  EQR has taken all action necessary to exempt
transactions between EQR and Lexford and its Affiliates from the operation of
any Takeover Statute.

    3.16  REGISTRATION STATEMENT.  The information with respect to EQR and the
EQR Subsidiaries included in the Registration Statement will not, as of the
effective date of the Registration Statement, contain 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.

    3.17  INVESTMENT COMPANY ACT OF 1940.  Neither EQR nor any of the EQR
Subsidiaries is, or at the Effective Time will be, required to be registered
under the 1940 Act.

    3.18  DEFINITION OF KNOWLEDGE OF EQR.  As used in this Agreement, the phrase
"to the Knowledge of EQR" (or words of similar import) means the knowledge of
those individuals identified in Schedule 3.18 to the EQR Disclosure Letter.

    3.19  VOTE REQUIRED.  Except for the EQR Shareholder Approvals, no other
vote or consent by the equity holders of EQR or any EQR Subsidiary (whether by
agreement, under applicable law or otherwise) is required to approve this
Agreement or the transactions contemplated hereby, nor will any such equity
holders be entitled to dissenters' rights or other rights of appraisal in
connection with the EQR Shareholder Approvals or the consummation of the
transactions contemplated by this Agreement.

    3.20  EMPLOYEE POLICIES.  Each employee plan or arrangement of EQR is in
material compliance with ERISA, to the extent subject to ERISA, and any other
applicable law governing such employee plan or arrangement.

    3.21  INSURANCE.  EQR has delivered to Lexford a true and complete summary
of all insurance policies of EQR currently in effect.

    3.22  YEAR 2000.  The information set forth under the caption "Year 2000
Issue" in EQR's quarterly report on Form 10-Q for the quarterly period ended
March 31, 1999 is true and correct as of the date hereof.

                                   COVENANTS

    4.1  ACQUISITION PROPOSALS.  Prior to the Effective Time, Lexford agrees
that:

        (a) neither it nor any of the Lexford Subsidiaries shall initiate,
    solicit or encourage, directly or indirectly, any inquiries or the making or
    implementation of any proposal or offer (including, without limitation, any
    proposal or offer to its shareholders) with respect to a merger,
    acquisition, tender offer, exchange offer, consolidation, sale of assets or
    similar transaction involving all or any significant portion of the assets
    or any equity securities of Lexford or any of the Lexford Subsidiaries,
    other than the transactions contemplated by this Agreement (any such
    proposal or offer being hereinafter referred to as an "Acquisition
    Proposal") or engage in any negotiations

                                      A-31
<PAGE>
    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 effort or attempt to make or implement an
    Acquisition Proposal;

        (b) it will use its best efforts not to permit any of its officers,
    trustees, employees, agents or financial advisors to engage in any of the
    activities described in Section 4.1(a);

        (c) it will immediately cease and cause to be terminated any existing
    activities, discussions or negotiations with any parties conducted
    heretofore with respect to any of the foregoing and will take the necessary
    steps to inform the individuals or entities referred to in Section 4.1(b) of
    the obligations undertaken in this Section 4.1; and

        (d) it will notify EQR immediately if Lexford 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 4.1 shall prohibit the
Board of Trustees of Lexford from (i) furnishing information to or entering into
discussions or negotiations with, any person or entity that makes an unsolicited
Acquisition Proposal, if, and only to the extent that (A) the Board of Trustees
of Lexford determines in good faith that failure to do so would create a
reasonable probability of a breach of its duties to shareholders imposed by law,
(B) prior to furnishing such information to, or entering into discussions or
negotiations with, such person or entity, Lexford provides written notice to EQR
to the effect that it is furnishing information to, or entering into discussions
with, such person or entity, and (C) subject to any confidentiality agreement
with such person or entity (which Lexford determined in good faith was required
to be executed in order for the Board of Trustees to comply with its duties to
shareholders imposed by law), Lexford keeps EQR informed of the status (not the
terms) of any such discussions or negotiations; and (ii) to the extent
applicable, complying with Rule 14e-2 or Rule 14d-9 promulgated under the
Exchange Act with regard to an Acquisition Proposal. Nothing in this Section 4.1
shall (x) permit Lexford to terminate this Agreement (except as specifically
provided in Article 7 hereof), (y) permit Lexford to enter into an agreement
with respect to an Acquisition Proposal during the term of this Agreement (it
being agreed that during the term of this Agreement, Lexford shall not enter
into an agreement with any Person that provides for, or in any way facilitates,
an Acquisition Proposal (other than a confidentiality agreement in customary
form executed as provided above)) or (z) affect any other obligation of Lexford
under this Agreement; provided, however, that the Board of Trustees of Lexford
may approve and recommend a Superior Acquisition Proposal and, in connection
therewith, withdraw or modify its approval or recommendation of this Agreement
and the Merger. As used herein, "Superior Acquisition Proposal" means a bona
fide Acquisition Proposal made by a third party which a majority of the members
of the Board of Trustees of Lexford determines in good faith to be more
favorable to Lexford's shareholders from a financial point of view than the
Merger and which the Board of Trustees of Lexford determines is reasonably
capable of being consummated.

Time, except as (i) contemplated by this Agreement, (ii) set forth in Schedule

Lexford shall, and shall cause each of the Lexford Subsidiaries to, conduct its
business only in the usual, regular and ordinary course and in substantially the
same manner as heretofore conducted, and, irrespective of whether or not in the
ordinary course of business, Lexford shall, and shall cause each of the Lexford
Subsidiaries to:

    organizations and goodwill and keep available the services of its officers

    change in the condition (financial or otherwise), business, properties,

    adversely affect Lexford's status as a qualified REIT under the Code;

        (g) not make or rescind any express or deemed election relative to Taxes
    (unless required by law or necessary to preserve Lexford's status as a REIT
    or the status of any Lexford Subsidiary as a partnership for federal income
    tax purposes or as a qualified REIT subsidiary under Section 856(i) of the
    Code, as the case may be);

    into any agreement or commitment to develop or construct other real estate
    projects;

        (i) not amend its Articles of Incorporation, Bylaws, Declaration of
    Trust, code of regulations or partnership agreement or comparable charter or
    organizational document or the articles of incorporation, Bylaws,

    membership interests or units of limited partnership interest, or any
    security the value of which is measured by shares of beneficial interest, or
    any security subordinated to the claim of its general creditors;

        (l) except (i) as provided in Section 5.12 hereof, (ii) in connection
    with the use of Lexford Shares to pay the exercise price or tax withholding
    in connection with equity-based employee benefit plans by the participants
    therein, or (iii) for dividends and distributions by a Lexford

    thereunder;

        (o) not pay, discharge or satisfy any material claims, liabilities or
    obligations (absolute, accrued, asserted or unasserted, contingent or

    ordinary course of business consistent with past practice, or in accordance
    with their terms, of liabilities reflected or reserved against in, or
    contemplated by, the most recent consolidated financial statements (or the
    notes thereto) furnished to EQR or incurred in the ordinary course of
    business consistent with past practice;

        (p) not enter into any commitment, contractual obligation, capital
    expenditure or transaction (each, a "Commitment") which may result in total
    payments or liability by or to it in excess of $250,000 or aggregate
    Commitments in excess of $500,000;

        (q) not guarantee the indebtedness of another Person, enter into any

    Agreement or any claim arising out of or in connection with the

    the intent of the parties to

                                      A-34
<PAGE>
    avoid, to the extent practicable, the termination of this Agreement pursuant

    or consolidate with, acquire all or substantially all of the assets of, or
    acquire the beneficial ownership of a majority of the outstanding capital
    stock or other equity interest in any person or entity;

        (z) use its reasonable best efforts to continue to qualify as a REIT
    prior to the Effective Time, and not enter into any transaction that would
    be considered a prohibited transaction as defined in Section 857(b)(6) of
    the Code; and

        (aa) take all action necessary to cause the payment of compensation
    customarily made at the end of each quarter to the Trustees of Lexford to be
    paid (i) with respect to the payment made at the end of the second quarter
    of 1999, in Lexford Common Shares valued as of the close of business on the
    first business day following the announcement of the execution of this
    Agreement and, with respect to each quarter thereafter, in Lexford Common
    Shares valued as of the close of business on the last business day prior to

For purposes of this Section 4.2 only, any contract, transaction or other event
shall be deemed to be material and to be subject to the terms hereof if it would

statement in excess of $500,000, or on Lexford's consolidated balance sheet in
excess of $500,000.

    4.3  CONDUCT OF EQR'S BUSINESS PENDING MERGER.  Prior to the Effective Time,
except as (i) contemplated by this Agreement, or (ii) consented to in writing by
Lexford, EQR shall, and shall cause each of the EQR Subsidiaries to:

        (a) use its reasonable efforts to preserve intact its business
    organizations and goodwill and keep available the services of its officers
    and employees;

        (b) confer on a regular basis with one or more representatives of
    Lexford to report operational matters of materiality which would have a EQR
    Material Adverse Effect;

        (c) promptly notify Lexford of any material emergency or other material
    change in the condition (financial or otherwise), business, properties,
    assets, liabilities, prospects or the normal course of its businesses or in
    the operation of its properties, or of any material governmental complaints,
    investigations or hearings (or communications indicating that the same may
    be contemplated);

        (d) promptly deliver to Lexford true and correct copies of any report,
    statement or schedule filed with the SEC subsequent to the date of this
    Agreement;

        (e) maintain its books and records in accordance with GAAP consistently
    applied;

        (f) duly and timely file all reports, tax returns and other documents
    required to be filed with federal, state, local and other authorities; and

                                      A-35
<PAGE>
        (g) use its reasonable best efforts to continue to qualify as a REIT
    prior to the Effective Time and not enter into any prohibited transaction
    that would be considered a prohibited transaction as defined in Section
    857(b)(6) of the Code.

For purposes of this Section 4.3 only, an emergency, change, complaint,
investigation or hearing shall be deemed material if it would reasonably be
expected to have an EQR Material Adverse Effect.

    4.4  OTHER ACTIONS.  Each of Lexford on the one hand and EQR on the other
hand shall not, and shall use its reasonable best efforts to cause their
Subsidiaries not to take, any action that would result in (i) any of the
representations and warranties of such party set forth in this Agreement that
are qualified as to materiality becoming untrue, (ii) any of such
representations and warranties that are not so qualified becoming untrue in any
material respect or (iii) except as contemplated by Section 4.1, any of the
conditions to the Merger set forth in Article 6 not being satisfied.

    4.5  FILING OF CERTAIN REPORTS.  The Surviving Trust shall file the reports
required to be filed by it under the Exchange Act and the rules and regulations
adopted by the SEC thereunder, and it will take such further action as any
Affiliate of Lexford or EQR may reasonably request, all to the extent required
from time to time to enable such Affiliate to sell shares of beneficial interest
of the Surviving Trust received by such Affiliate in the Merger without
registration under the Securities Act pursuant to (i) Rule 145(d)(1) under the
Securities Act, as such Rule may be amended from time to time, or (ii) any
successor rule or regulation hereafter adopted by the SEC.

    4.6  COMPLIANCE WITH THE SECURITIES ACT.  No later than ten (10) days prior
to the Effective Time, Lexford shall cause to be prepared and delivered to EQR a
list identifying all persons who, at the time of the Lexford and EQR
Shareholders Meetings (as defined in Section 5.1 hereto), may reasonably be
deemed to be "affiliates" of Lexford as that term is used in paragraphs (c) and
(d) of Rule 145 under the Securities Act (the "Affiliates"). Lexford shall use
its reasonable efforts to cause each person who is identified as an Affiliate in
such list to deliver to Lexford on or prior to the Effective Time a written
agreement, in the form previously approved by the parties hereto, that such
Affiliate will not sell, pledge, transfer or otherwise dispose of any EQR Common
Shares issued to such Affiliate pursuant to the Merger, except pursuant to an
effective registration statement under the Securities Act or in compliance with

agreements on the certificates representing any EQR Common Shares to be received
by such Affiliates pursuant to the terms of this Agreement, and to issue
appropriate stop transfer instructions to the transfer agent for the EQR Common
Shares, consistent with the terms of such agreements.

    5.1  PREPARATION OF THE REGISTRATION STATEMENT AND THE PROXY STATEMENT;
LEXFORD SHAREHOLDERS MEETING AND EQR SHAREHOLDERS MEETING.

        (a) Lexford and EQR shall use their reasonable best efforts to prepare
and file with the SEC the Registration Statement, a portion of which shall also
serve as the Proxy Statement, in form and substance satisfactory to each of EQR
and Lexford. To the extent practicable, the parties shall utilize one document
for transmittal to their respective shareholders to meet applicable legal
requirements. Each of Lexford and EQR shall promptly use its reasonable best
efforts to (i) respond to any comments of the SEC and (ii) with respect to EQR
only, have the Registration Statement declared effective under the Securities
Act and the rules and regulations promulgated thereunder as promptly as
practicable after such filing and to keep the Registration Statement effective
as long as is necessary to consummate the Merger. Each of Lexford and EQR will
use its reasonable best efforts to cause the

                                      A-36
<PAGE>
Proxy Statement to be mailed to Lexford's shareholders and EQR's shareholders,
respectively, as promptly as practicable after the Registration Statement is
declared effective under the Securities Act. Each party agrees to date its Proxy
Statement as of the same date, which shall be the approximate date of mailing to
the shareholders of the respective parties. Each party will notify the other
promptly of the receipt of any comments from the SEC and of any request by the
SEC for amendments or supplements to the Registration Statement or the Proxy
Statement or for additional information and will supply the other with copies of
all correspondence between such party or any of its representatives and the SEC,
with respect to the Registration Statement or the Proxy Statement. The
respective parties will cause the Registration Statement and the Proxy Statement
to comply in all material respects with all applicable requirements of law.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Registration Statement or the Proxy Statement, EQR or Lexford,
as the case may be, shall promptly inform the other of such occurrences and
cooperate in filing with the SEC and/or mailing to the shareholders of EQR and
the shareholders of Lexford such amendment or supplement to the Proxy Statement.
EQR also shall take any action required to be taken under any applicable state
securities or "blue sky" laws in connection with the issuance of shares of
beneficial interest of the Surviving Trust pursuant to the Merger, and Lexford
shall furnish all information concerning Lexford and the holders of Lexford
Shares and rights to acquire Lexford Shares as may be reasonably requested in
connection with any such action.

        (b) EQR will, as soon as practicable following the date of this
Agreement (but in no event sooner than 20 business days following the date the
Proxy Statement is mailed to the shareholders of EQR), duly call, give notice
of, convene and hold a meeting of its shareholders (the "EQR Shareholders
Meeting") for the purpose of obtaining the EQR Shareholder Approvals. EQR will,
through its Board of Trustees, recommend to its shareholders approval of this
Agreement, the Merger, and the transactions contemplated by this Agreement.

        (c) Lexford will, as soon as practicable following the date of this
Agreement (but in no event sooner than 20 business days following the date the
Proxy Statement is mailed to the shareholders of Lexford), duly call, give
notice of, convene and hold a meeting of its shareholders (the "Lexford
Shareholders Meeting", and, together with the EQR Shareholders Meeting, the
"Shareholders Meetings") for the purpose of obtaining the Lexford Shareholder
Approvals. Lexford will, through its Board of Trustees, recommend to its
shareholders approval of this Agreement, the Merger and the transactions
contemplated by this Agreement; PROVIDED, that prior to the Lexford Shareholders
Meeting, such recommendation may be withdrawn, modified or amended to the extent
that, as a result of the commencement or receipt of a proposal constituting a
Superior Acquisition Proposal, the Board of Trustees of Lexford determines in
good faith that such withdrawal, modification or amendment is appropriate.

        (d) EQR and Lexford shall use their best efforts to hold their
respective shareholder meetings on the same day, which day, subject to the
provisions of Sections 5.1(b) and 5.1(c), shall be a day not later than 35 days
after the date the Proxy Statement is mailed.

        (e) If on the date for the EQR Shareholders Meeting and Lexford
Shareholders Meeting established pursuant to Section 5.1(d) of this Agreement,
either EQR or Lexford has not received a sufficient number of proxies to approve
the Merger (but less than a majority of the outstanding common shares of
beneficial interest of such party have voted against the Merger), then both
parties shall adjourn their respective shareholders meetings until the first to
occur of (i) the date ten (10) days after the originally scheduled date of the
shareholders meetings or (ii) the date on which the requisite number of proxies
approving the Merger has been obtained or proxies have been received
representing more than a majority of its outstanding common shares of beneficial
interest which voted against the Merger.

        (f) Lexford acknowledges that EQR may also call the EQR Shareholders
Meeting for the separate approval of an amendment to the EQR Declaration to
provide for shareholder approval of mergers and other trust transactions only
when required under Maryland law. In the event of approval of such amendment by
the shareholders of EQR, the Articles of Merger will effectuate such amendment.

    5.2  ACCESS TO INFORMATION: CONFIDENTIALITY.  Subject to the requirements of
confidentiality agreements with third parties, each of Lexford and EQR shall,
and shall cause each of the Lexford Subsidiaries and EQR Subsidiaries,
respectively, to afford to the other party and to the officers, employees,
accountants, counsel, financial advisors and other representatives of such other
party, reasonable access during normal business hours prior to the Effective
Time to all their respective properties, books, contracts, commitments,

respectively, to furnish promptly to the other party (a) a copy of each report,
schedule, registration statement and other document filed by it during such
period pursuant to the requirements of federal or state securities laws and (b)
all other information concerning its business, properties and personnel as such
other party may reasonably request. Each of Lexford and EQR shall, and shall
cause the Lexford Subsidiaries and EQR Subsidiaries, respectively, to use
commercially reasonable efforts to cause its officers, employees, accountants,
counsel, financial advisors and other representatives and affiliates to, hold
any nonpublic information in confidence to the extent required by, and in
accordance with, and will comply with the provisions of the letter agreements
dated as of March 25, 1999 and June 4, 1999 between Lexford and EQR (the
"Confidentiality Agreements").

all such necessary action.

        (b) Lexford shall give prompt notice to EQR, and EQR shall give prompt
notice to Lexford, (i) if any representation or warranty made by it contained in
this Agreement that is qualified as to materiality becomes untrue or inaccurate
in any respect or any such representation or warranty that is not so qualified
becomes untrue or inaccurate in any material respect or (ii) of the failure by
it to comply with or satisfy in any material respect any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement; provided,
however, that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

    5.4  COSTS OF TRANSACTION.  In the event that the Merger is not consummated,
each of EQR and Lexford shall pay their own costs and expenses relating to the

paid 50% by Lexford and 50% by EQR and (ii) all printing costs shall be paid by

                                      A-38
<PAGE>

    5.5  TAX TREATMENT.  Each of EQR and Lexford shall use its reasonable best
efforts to cause the Merger to qualify as a reorganization under the provisions

    5.6  PUBLIC ANNOUNCEMENTS.  EQR and Lexford will consult with each other
before issuing, and 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, including the Merger, and shall not

Common Shares to be issued in the Merger and listed on the NYSE after the
Effective Time.

    5.8  LETTERS OF ACCOUNTANTS.

        (a) Lexford shall use its reasonable best efforts to cause to be
delivered to EQR on or before the date of the mailing of the Proxy Statement,
the "comfort" letter of Ernst & Young, LLP, Lexford's independent public
accountants, of the kind contemplated by the Statement of Auditing Standards
with respect to Letters to Underwriters promulgated by the American Institute of
Certified Public Accountants (the "AICPA Statement"), dated and delivered the
date on which the Registration Statement shall become effective and as of the
Effective Time, and addressed to EQR, (i) in form and substance reasonably
satisfactory to EQR and reasonably customary in scope and substance for letters
delivered by independent public accountants in connection with transactions such
as those contemplated by this Agreement and (ii) confirming the information set
forth in Schedule 5.8 to the Lexford Disclosure Letter.

        (b) EQR shall use its reasonable best efforts to cause to be delivered
to Lexford on or before the date of the mailing of the Proxy Statement, the
"comfort" letter of Ernst & Young LLP, EQR's independent public accountants, of
the kind contemplated by the AICPA Statement, dated the date on which the
Registration Statement shall become effective and as of the Effective Time, and
addressed to Lexford, in form and substance reasonably satisfactory to Lexford
and reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with transactions such as those
contemplated by this Agreement.

    5.9  TAXES.

        (a) EQR and Lexford shall cooperate in the preparation, execution and
filing of all returns, questionnaires, applications or other documents regarding
any real property transfer or gains, sales, use, transfer, value added stock
transfer and stamp taxes, any transfer, recording, registration and other fees
and any similar taxes which become payable in connection with the transactions
contemplated by this Agreement (together with any related interests, penalties
or additions to tax, "Transfer and Gains Taxes"). From and after the Effective
Time, the Surviving Trust shall, or shall cause ERP Operating Partnership, as
appropriate, to pay or cause to be paid, without deduction or withholding from
any

                                      A-39
<PAGE>
amounts payable to the holders of beneficial interests in the Surviving Trust,
all Transfer and Gains Taxes.

        (b) Lexford will consult with and provide EQR the opportunity to review
and comment upon all returns, questionnaires, applications or other documents to
be filed after the date hereof by Lexford with respect to Taxes including,
without limitation, Lexford's federal, state and local income tax returns for
its taxable year ended December 31, 1998 (collectively, the "Lexford Tax
Returns"), and shall not file any such returns without the prior review and
comment of EQR, which shall not be unreasonably delayed.

        (c) Lexford will cause each Lexford Subsidiary to consult with and
provide EQR the opportunity to review and comment upon all returns,
questionnaires, applications or other documents to be filed after the date
hereof by each respective Lexford Subsidiary with respect to Taxes including,
without limitation, each Lexford Subsidiary's federal, state and local income
tax returns for its taxable year ended December 31, 1998 (collectively, the
"Lexford Subsidiary Tax Returns"), and Lexford shall not cause any Lexford
Subsidiary to file any such returns without the prior review and comment of EQR,
which shall not be unreasonably delayed.

        (d) If the treatment of any partnership item on any Lexford Tax Return
or Lexford Subsidiary Tax Return proposed to be filed by Lexford or a Lexford
Subsidiary is or may be inconsistent with the treatment of such item on the
applicable partnership return under Section 6222(b)(1)(A) of the Code, then EQR
shall have the right to cause Lexford to file such Lexford Tax Return and/or
Lexford Subsidiary Tax Return in a manner which is not inconsistent with the
applicable partnership return, provided that (i) EQR makes a loan to Lexford
having the terms and conditions set forth below in the principal amount equal to
the amount of any increase in the tax liability reported on the applicable
Lexford Tax Return or Lexford Subsidiary Tax Return for the taxable year ended
December 31, 1998, solely resulting from the treatment of such partnership item
in the manner requested by EQR (the "Lexford Tax"), and (ii) the treatment of
the partnership item in the manner requested by EQR (including the reporting and
payment of any tax in respect of such item) will not jeopardize Lexford's status
as a REIT for its taxable year ended December 31, 1998. Any loan made by EQR
pursuant to this Section 5.9(d) shall be made on the date that the Lexford Tax
is paid by Lexford or a Lexford Subsidiary and shall be evidenced by a
promissory note reasonably satisfactory to Lexford and EQR providing for (i)
repayment of the principal amount in sixteen (16) equal quarterly installments,
(ii) quarterly payments of interest at a rate equal to the Prime Rate plus one
percent (1%), compounded quarterly, (iii) acceleration of the unpaid principal
amount in the event Lexford shall consummate a merger, consolidation, sale of
substantiality all of its assets or other transaction involving a change in
control of Lexford, and (iv) such other terms and conditions as may be agreed
upon by EQR and Lexford. For purposes of this Section 5.9(d), the term "Prime
Rate" shall mean the rate of interest published from time to time as the "Prime
Rate" in the "Money Rates" column of THE WALL STREET JOURNAL, or if THE WALL
STREET JOURNAL ceases or fails to publish such rate, the prime rate, corporate

    5.10  BENEFIT PLANS AND OTHER EMPLOYEE ARRANGEMENTS.

        (a) BENEFIT PLANS. After the Effective Time, all employees of Lexford
who are employed by the Surviving Trust shall, at the option of the Surviving
Trust, either continue to be eligible to participate in an "employee benefit
plan", as defined in Section 3(3) of ERISA, currently maintained by Lexford
which is, at the option of the Surviving Trust, continued by the Surviving
Trust, or alternatively, shall be eligible to participate in the same manner as
other similarly situated employees of the Surviving Trust who were formerly
employees of EQR in any "employee benefit plan," as defined in Section 3(3) of
ERISA, sponsored or maintained by the Surviving Trust for similarly situated
employees after the Effective Time. With respect to each such employee benefit
plan, service with

                                      A-40
<PAGE>
EQR or any EQR Subsidiary or with Lexford or any Lexford Subsidiary (as
applicable) shall be included for purposes of determining eligibility to
participate and vesting (if applicable). With respect to medical benefits
provided by the Surviving Trust on and after the Closing Date, (i) coverage that
would otherwise be denied due to a preexisting illness shall be provided to
those employees who had such coverage under a plan sponsored by EQR, Lexford or
any of the EQR Subsidiaries or Lexford Subsidiaries before the Closing Date
(each, a "Prior Plan"), (ii) unless required by law, no such employee shall be
required to observe any waiting period prior to entitlement to such benefits and
(iii) each such employee shall be credited as to previously paid deductible and
co-payment amounts under any Prior Plan.

        (b) SEVERANCE PROGRAMS. Lexford has adopted three severance programs
(the "Severance Programs"), all of which are specifically described in Schedule
2.15A to the Lexford Disclosure Letter. Schedule 2.15A to the Lexford Disclosure
Letter also sets forth those officers and trustees (the "Lexford Schedule 2.15A
Personnel") who may be offered a payment at the Effective Time pursuant to a
Severance Program, as well as the amount of each such payment. The Surviving
Trust shall maintain the Severance Programs in accordance with the terms thereof
as of the date hereof. In no event shall Lexford amend, modify or alter in any
manner any Severance Program or adopt or agree to any other severance programs,
agreements or arrangements. Neither the Severance Programs nor any other term of
this Agreement shall require the Surviving Trust to continue the employment of
any employee of Lexford after the Effective Time. As a condition to receiving a
payment under any Severance Program, each of the Lexford Schedule 2.15A
Personnel and each other terminated employee shall execute and deliver to
Lexford an agreement and release as described in or attached to Schedule 5.10 (a
"Release"). Lexford hereby acknowledges that the terms of the Release provide
that if the Lexford Schedule 2.15A Personnel executing such Release has entered
into a Note, such Lexford Schedule 2.15A Personnel shall pay in full or secure
all amounts due under such Note at the time payment is received pursuant to the
Severance Programs with such security to equal or exceed 150% of the outstanding
balance of the Note.

        (c) OPTIONEES.

        (i) Prior to the Closing, Lexford will, through its Board of Trustees
(or any committee thereof), take all action required for the cancellation as of
the Effective Time of the vested portion of all Lexford Options held by those
individuals specified by EQR, including, without limitation, Lexford Trustees (a
list of which will be provided to Lexford at least 10 business days prior to the
Effective Time), in consideration for cash in an amount equal to the difference
between the Closing Price of a Lexford Common Share and the applicable exercise
price set forth in such option, multiplied by the number of Lexford Common
Shares subject to such option to the extent such option is vested at the
Effective Time, it being understood that all Lexford Options held by employees
whose employment does not continue after the Effective Time shall be deemed
vested as of the Effective Time. EQR shall promptly, and in any event no later
than ten business days prior to the Effective Time, notify in writing each
individual holding a Lexford Option whose employment is not to continue after
the Effective Time, with such notification to set forth the rights of such
employee pursuant to this subsection. Lexford shall use reasonable efforts to
assist EQR in such notification process. For purposes of this paragraph,
"Closing Price" shall mean the unweighted average closing price of a Lexford
Common Share, reported as "New York Stock Exchange Composite Transactions" by
THE WALL STREET JOURNAL (Midwest Edition) for the ten (10) Trading Days ending
on the third Trading Day immediately prior to the Closing Date. For the purposes
of the paragraph only, "Trading Day" shall mean any day on which Lexford Common
Shares are traded on the NYSE.

        (ii) Lexford and EQR agree to take all appropriate action to cause each
Lexford Option which remains unexercised as of the Effective Time (other than
those options to be cancelled pursuant to Section 5.10(c)(i)) to be amended to
(i) adjust the number of shares for which such option is thereafter exercisable
by multiplying such number of shares by the Exchange Ratio, (ii) adjust the per

                                      A-41
<PAGE>
share exercise price by dividing such exercise price by the Exchange Ratio, and
(iii) to provide that such option shall be exercisable for EQR Common Shares.
Accordingly, as more fully described in the Lexford option plan pursuant to
which each such Lexford Option was granted (each a "Plan"), upon conversion of
the number of shares and the exercise price, all Lexford Options which have been
converted into EQR Options shall remain subject to such Plan's terms. EQR agrees
to register the shares subject to the Plans on a registration statement on Form
S-8 filed with the SEC as soon as practicable following the Effective Time.

        (iii) From and after the date hereof, Lexford, through its Board of
Trustees or otherwise, will not modify any Plan or authorize, and Lexford will
not grant, any Lexford Options or Restricted Share Grants.

        (d) WITHHOLDING. Lexford shall require each employee who exercises a
Lexford Option, receives Lexford Shares pursuant to any existing commitment, or
otherwise receives any payment from Lexford as a result of the transactions
contemplated by this Agreement, to pay to Lexford in cash or Lexford Shares an
amount sufficient to satisfy in full Lexford's obligation to withhold Taxes
incurred by reason of such exercise, issuance or receipt.

        (e) PAYMENTS. The compensation, benefits, payments, accelerations, and
share options of the executives and trustees of Lexford, as set forth in
Schedule 2.15 of the Lexford Disclosure Letter, shall be satisfied at the
Effective Time or as otherwise set forth in this Agreement in accordance with
the terms set forth in Schedule 2.15 and Schedule 5.10(e) to the Lexford
Disclosure Letter. As a condition to each employee and trustee of Lexford
receiving the compensation, benefits, payments, accelerations and share options
described in this Section 5.10(e), such employee or trustee shall execute a
Release.

    5.11  INDEMNIFICATION.

        (a) From and after the Effective Time, EQR shall provide exculpation and
indemnification for each person who is now or has been at any time prior to the
date hereof or who becomes prior to the Effective Time, an officer or trustee of
Lexford or any Lexford Subsidiary (the "Indemnified Parties") which is the same
as the exculpation and indemnification provided to the Indemnified Parties by
Lexford (including advancement of expenses, if so provided) immediately prior to
the Effective Time in its Declaration of Trust, Bylaws, or any Employee Plan as
in effect at the close of business on the date hereof; PROVIDED, that such
exculpation and indemnification covers actions on or prior to the Effective
Time, including, without limitation, all transactions contemplated by this
Agreement. EQR shall obtain and maintain in effect at the Effective Time and
continuing until the sixth anniversary thereof "run-off" trustees and officers
liability insurance with a coverage amount and other terms and conditions
comparable to Lexford's current trustees and officers liability insurance policy
covering the trustees and officers of Lexford with respect to their service as
such prior to the Effective Time (the "Run-Off Policy"). EQR shall provide
Lexford with a true and complete copy of a binder with respect to the Run-Off
Policy at least 10 days prior to the Effective Time, and shall use its
reasonable best efforts to provide to Lexford a true and complete copy of the
Run-Off Policy as proposed to be issued prior to the Effective Time. The premium
for such policy shall be paid in full at the Effective Time.

        (b) The provisions of this Section 5.11 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her personal representatives and shall be binding on all
successors and assigns of EQR and Lexford. EQR agrees to pay all costs and
expenses (including fees and expenses of counsel) that may be incurred by any
Indemnified Party or his or her heirs or his or her personal representatives in
successfully enforcing the indemnity or other obligations of EQR under this
Section 5.11. The provisions of this Section 5.11 shall survive the Merger and
are in addition to any other rights to which an Indemnified Party may be
entitled.

        (c) In the event that the Surviving Trust or any of its respective
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving

                                      A-42
<PAGE>
corporation or entity of such consolidation or merger or (ii) transfers all or
substantially all of its properties and assets to any person, then, and in each
such case the successors and assigns of such entity shall assume the obligations
set forth in this Section 5.11, which obligations are expressly intended to be
for the irrevocable benefit of, and shall be enforceable by, each trustee and
officer covered hereby.

    5.12  DECLARATION OF DIVIDENDS AND DISTRIBUTIONS.  From and after the date
of this Agreement, Lexford shall not make any dividend or distribution to its
shareholders without the prior written consent of EQR; PROVIDED, HOWEVER, the
written consent of EQR shall not be required for the authorization and payment
of quarterly distributions with respect to the Lexford Common Shares of (i) up
to $0.4325 per share for a dividend with a record date of June 30, 1999, to be
paid on or about July 15, 1999 (the "Second Quarter Dividend") and (ii) an
amount per share for each quarterly dividend thereafter not to exceed an amount
equal to the dividend on a EQR Common Share for such quarter multiplied by the
Exchange Ratio; PROVIDED FURTHER, that the record and payment dates for each
distribution with respect to the Lexford Common Shares (other than the Second
Quarter Dividend) shall be the same date as the record and payment dates for the
quarterly distribution for the EQR Common Shares, as provided to Lexford by
written notice not less than twenty (20) business days prior to the record date
for such quarterly EQR distribution. In the event that a distribution with
respect to Lexford Common Shares permitted by this Section 5.12 has (i) a record
date prior to the Effective Time and (ii) has not been paid as of the Effective
Time, the holders of Lexford Common Shares shall be entitled to receive such
distribution as set forth in the Articles of Merger.

    5.13  TRANSFER OF LEXFORD ASSETS AFTER EFFECTIVE TIME.  Lexford acknowledges
that immediately after the Effective Time, any real properties owned by Lexford
and the Lexford Subsidiaries (or the equity interests in the entity then holding
such properties) and the equity interests in certain of the Lexford Subsidiaries
shall be transferred through one or more transactions to ERP Operating
Partnership, subject to all liabilities of Lexford and the Lexford Subsidiaries,
as a capital contribution in exchange for a number of units and preferred units
of ERP Operating Partnership equal to the number of common shares of beneficial
interest and preferred shares of beneficial interest of the Surviving Trust
issued in the Merger to the owners of the shares of beneficial interest of
Lexford in the Merger; provided, however, that Lexford makes no representation
or warranty regarding EQR's ability to accomplish the foregoing, the costs that
would be incurred, whether under Section 5.9 hereof or otherwise, in connection
therewith or any consents or approvals that may be required therefor.

    5.14  NOTICES.  Each party hereto shall provide such notice to its
shareholders of the Merger and other transactions contemplated hereby as is
required under Maryland law.

    5.15  RESIGNATIONS.  On the Closing Date, if requested by EQR, Lexford shall
cause the trustees, directors and officers of Lexford and each of the Lexford
Subsidiaries to submit their resignations from such positions, effective as of
the Effective Time.

    5.16  THIRD PARTY MANAGEMENT AGREEMENTS AND OUTSIDE MANAGEMENT
AGREEMENTS.  Lexford will not, and will not permit any Lexford Subsidiary to,
(i) amend the Third Party Management Agreements and Outside Management
Agreements, (ii) renew the Third Party Management Agreements except on terms
which permit its cancellation by Lexford or the applicable Lexford Subsidiary on
thirty days notice without charge, penalty or other cost for such cancellation,
and (iii) renew any Outside Management Agreement except on terms which are the
same as the existing Outside Management Agreement or are more favorable to
Lexford or the applicable Lexford Subsidiary than the existing Outside
Management Agreement.

    5.17  CREDIT FACILITY.  At the Closing, all amounts due under any credit
facility between Lexford or any Lexford Subsidiary and Provident Bank will be
prepayable without fee or penalty.

    7.1  TERMINATION.  This Agreement may be terminated at any time prior to the
acceptance of the Articles of Merger for record by the Department, whether
before or after either of the Shareholder Approvals are obtained:

        (a) by mutual written consent duly authorized by both the Boards of
    Trustees of EQR and Lexford;

        (b) by EQR, upon a breach of any representation, warranty, covenant,
    obligation or agreement on the part of Lexford set forth in this Agreement,
    in either case such that the conditions set forth in Section 6.2(a) or
    Section 6.2(b), as the case may be, would be incapable of being satisfied by
    December 31, 1999 (or as otherwise extended);

        (c) by Lexford, upon a breach of any representation, warranty, covenant
    obligation or agreement on the part of EQR set forth in this Agreement, in

<PAGE>
    set forth in Section 6.3(a) or Section 6.3(b), as the case may be, would be
    incapable of being satisfied by December 31, 1999 (or as otherwise
    extended);

        (d) by either EQR or Lexford, if any judgment, injunction, order, decree
    or action by any Governmental Entity of competent authority preventing the
    consummation of the Merger shall have become final and nonappealable;

        (e) by either EQR or Lexford, if the Merger shall not have been
    consummated before December 31, 1999; provided, that in the case of
    termination pursuant to this Section 7.1(e), the terminating party shall not
    have breached in any material respect its obligations under this Agreement
    in any manner that shall have proximately contributed to the occurrence of
    the failure referred to in this Section and, provided further, that (i) if
    the Merger shall not have been consummated solely by reason of the failure
    to meet the condition set forth in Section 6.2(i)(y), December 31, 1999
    shall be automatically extended to March 31, 2000 and (ii) any termination
    of this Agreement resulting solely by reason of such failure to meet the
    condition set forth in Section 6.2(i)(y) shall be pursuant to this Section
    7.1(e);

        (f) by either EQR or Lexford if, upon a vote at a duly held Lexford

        (g) by either EQR or Lexford if, upon a vote at a duly held EQR

        (h) by Lexford, if prior to the Lexford Shareholders Meeting, the Board
    of Trustees of Lexford shall have withdrawn or modified its approval or
    recommendation of the Merger or this Agreement in connection with, or
    approved or recommended, a Superior Acquisition Proposal; and

        (i) by EQR if (i) prior to the Lexford Shareholders Meeting, the Board
    of Trustees of Lexford shall have withdrawn or modified in any manner
    adverse to EQR its approval or recommendation of the Merger or this
    Agreement in connection with, or approved or recommended, any Superior
    Acquisition Proposal, or (ii) Lexford shall have entered into a definitive
    agreement with respect to any Acquisition Proposal.

    7.2  CERTAIN FEES AND EXPENSES.  If this Agreement shall be terminated (i)
pursuant to Section 7.1(h) or 7.1(i), then Lexford will pay EQR (provided
Lexford was not entitled to terminate this Agreement pursuant to Section 7.1(c)
at the time of such termination) a fee equal to the Expense Fee (as defined
below), or (ii) pursuant to Section 7.1(b) or 7.1(f), then Lexford will pay EQR
(provided Lexford was not entitled to terminate this Agreement pursuant to
Section 7.1(c) at the time of such termination) an amount equal to the Expense
Fee (as defined below). If this Agreement shall be terminated pursuant to
Section 7.1(c) or 7.1(g), then EQR will pay Lexford (provided EQR was not
entitled to terminate this Agreement pursuant to Section 7.1(b) at the time of
such termination), an amount equal to the Expense Fee. If the Merger is not
consummated (other than due to the termination of this Agreement pursuant to
Section 7.1(a), 7.1(c) or 7.1(g), by EQR pursuant to 7.1(e) or by Lexford after
March 31, 2000 pursuant to 7.1(e)), and at the time of the termination of this
Agreement an Acquisition Proposal has been received by Lexford, and either prior
to the termination of this Agreement or within twelve (12) months thereafter
Lexford or any Lexford Subsidiary enters into any written Acquisition Proposal
which is subsequently consummated (whether or not such Acquisition Proposal is
the same Acquisition Proposal which had been received at the time of the
termination of this Agreement), then Lexford shall pay the Break-Up Fee to EQR.
The payment of the Break-Up Fee shall be compensation and liquidated damages for
the loss suffered by EQR as a result of the failure of the Merger to be
consummated and to avoid the difficulty of determining damages under the
circumstances and neither party shall have any other liability to the other
after the

                                      A-47
<PAGE>
payment of the Break-Up Fee. The Break-Up Fee shall be paid by Lexford to EQR,
or the Expense Fee shall be paid by Lexford to EQR or EQR to Lexford (as
applicable), in immediately available funds within fifteen (15) days after the
date of the event giving rise to the obligation to make such payment occurred.
As used in this Agreement, "Break-Up Fee" shall be an amount equal to the lesser
of (i) $8,000,000 plus the Expense Fee (the "Base Amount") and (ii) the sum of
(A) the maximum amount that can be paid to EQR without causing it to fail to
meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if
the payment of such amount did not constitute income described in Sections
856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code ("Qualifying Income"), as
determined by independent accountants to EQR, and (B) in the event EQR receives
a letter from outside counsel (the "Break-Up Fee Tax Opinion") indicating that
EQR has received a ruling from the IRS holding that EQR's receipt of the Base
Amount would either constitute Qualifying Income or would be excluded from gross
income within the meaning of Sections 856(c)(2) and (3) of the Code (the "REIT
Requirements") or that the receipt by EQR of the excess of the Base Amount over
the amount payable in clause (A) following the receipt of and pursuant to such
ruling would not be deemed constructively received prior thereto, the Base
Amount less the amount payable under clause (A) above. In the event that EQR is
not able to receive the full Base Amount, Lexford shall place the unpaid amount
in escrow and shall not release any portion thereof to EQR unless and until
Lexford receives any one or combination of the following: (i) a letter from
EQR's independent accountants indicating the maximum amount that can be paid at
that time to EQR without causing EQR to fail to meet the REIT Requirements or
(ii) a Break-Up Fee Tax Opinion, in which event Lexford shall pay to EQR the
lesser of the unpaid Base Amount or the maximum amount stated in the letter
referred to in (i) above. Lexford's obligation to pay any unpaid portion of the
Break-Up Fee shall terminate three years from the date of this Agreement. The
"Expense Fee" payable to EQR or Lexford, as the case may be (the "Recipient"),
shall be an amount equal to the least of (i) $4,000,000, (ii) the Recipient's
documented out-of-pocket expenses incurred in connection with this Agreement and
the transactions contemplated hereby (including, without limitation, all
attorneys', accountants' and investment bankers' fees and expenses) and (iii)
the sum of (A) the maximum amount that can be paid to the Recipient without
causing it to fail to meet the requirements of Sections 856(c)(2) and (3) of the
Code determined as if the payment of such amount did not constitute Qualifying
Income, as determined by independent accountants to the Recipient, and (B) in
the event the Recipient receives a Break-Up Fee Tax Opinion indicating that the
Recipient has received a ruling from the IRS holding that the Recipient's
receipt of the Expense Fee would either constitute Qualifying Income or would be
excluded from gross income within the meaning of the REIT Requirements or that
receipt by the Recipient of the excess of the Expense Fee over the amount
payable under clause (A) following the receipt of and pursuant to such ruling
would not be deemed constructively received prior thereto, the Expense Fee less
the amount payable under clause (A) above. In the event that the Recipient is
not able to receive the full Expense Fee, the Payor shall place the unpaid
amount in escrow and shall not release any portion thereof to the Recipient
unless and until the Payor receives any one or combination of the following: (i)
a letter from the Recipient's independent accountants indicating the maximum
amount that can be paid at that time to the Recipient without causing the
Recipient to fail to meet the REIT Requirements or (ii) a Break-Up Fee Tax
Opinion, in which event the Payor shall pay to the Recipient the lesser of the
unpaid Expense Fee or the maximum amount stated in the letter referred to in (i)
above. The obligation of EQR or Lexford, as applicable ("Payor"), to pay any
unpaid portion of the Expense Fee shall terminate three years from the date of
this Agreement.

    7.3  EFFECT OF TERMINATION.  In the event of termination of this Agreement
by either Lexford or EQR as provided in Section 7.1, this Agreement shall
forthwith become void and have no effect, without any liability or obligation on
the part of EQR, or Lexford, other than the last sentence of Section 5.2,
Section 7.2, this Section 7.3 and Article 8; provided that (a) if this Agreement
is terminated by EQR pursuant to Section 7.1(b), Lexford shall not be entitled
to any of the benefits of

                                      A-48
<PAGE>
Section 7.2, or (b) if this Agreement is terminated by Lexford pursuant to
Section 7.1(c), EQR shall not be entitled to any of the benefits of Section 7.2.

    7.4  AMENDMENT.  This Agreement may be amended by the parties in writing by
action of their respective Boards of Trustees at any time before or after any
Shareholder Approvals are obtained and prior to the filing of the Articles of
Merger with the Department; PROVIDED, HOWEVER, that, after the Shareholder
Approvals are obtained, no such amendment, modification or supplement shall be
made which by law requires the further approval of shareholders without
obtaining such further approval.

    7.5  EXTENSION; WAIVER.  At any time prior to the Effective Time, the
parties may (a) extend the time for the performance of any of the obligations or
other acts of the other party, (b) waive any inaccuracies in the representations
and warranties of the other party contained in this Agreement or in any document
delivered pursuant to this Agreement or (c) subject to the proviso of Section
7.4, waive compliance with any of the agreements or conditions of the other
party contained in this Agreement. Any agreement on the part of a party to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of those rights.

                                   ARTICLE 8
                               GENERAL PROVISIONS

after the Effective Time.

                                      B-2

    9.  CONVERSION.  The manner of converting the shares of Lexford shall be as
follows:

        (a) Subject to the provisions of Section 9(c) hereof, at the Effective
    Time, each share of Lexford Common outstanding immediately prior to the
    Effective Time shall, without any action on the part of the holder thereof,
    be converted into 0.463 of a share of EQR Common.

        (b) At the Effective Time, each certificate evidencing outstanding
    shares of Lexford Common will, without any action on the part of the holder
    thereof, thereafter represent the right to receive, without interest, a
    certificate evidencing the EQR Common as calculated pursuant to Section 9(a)
    above and cash in lieu of fractional shares of the EQR Common in accordance
    with Section 9(c), upon the surrender of such Lexford certificate or
    certificates.

        (c) Notwithstanding any other provision hereof, no fractional shares of
    EQR Common shall be issued in connection with the Merger. Instead, each
    holder of outstanding Lexford Common having a fractional interest arising
    upon the conversion or exchange of such shares in connection with the Merger
    shall, at the time of surrender of its Lexford certificate or certificates,
    be paid an amount in cash equal to the Closing Price (as hereinafter
    defined) multiplied by the fraction of a share of EQR Common to which such
    holder would otherwise be entitled. In the event that any one holder holds
    more than one certificate evidencing Lexford Common, the shares evidenced by
    all such certificates surrendered together for conversion or exchange shall
    be aggregated and one new certificate evidencing EQR Common shall be issued
    in respect of such certificates evidencing Lexford Common, insofar as is
    necessary to reduce the number of fractional interests in respect of EQR
    Common which would otherwise arise. No such holder shall be entitled to
    dividends or other distributions, voting rights or any other shareholder
    rights in respect of any fractional share. For purposes of this Section
    9(c), "Closing Price" shall mean the unweighted average closing price of a
    share of EQR Common (as reported in the New York Stock Exchange, Inc.
    Composite Tape) for the five (5) Trading Days immediately preceding the
    Effective Date, and "Trading Day" shall mean any day on which EQR Common is
    traded on the New York Stock Exchange and reported on its Composite Tape.

        (d) At the Effective Time, each outstanding option to purchase Lexford
    Common (a "Lexford Share Option" or collectively "Lexford Share Options")
    shall be amended to (i) adjust the number of shares for which such option is
    thereafter exercisable by multiplying such number of shares by 0.463, (ii)
    adjust the per share exercise price by dividing such exercise price by 0.463
    and (iii) to provide that such option shall be exercisable for shares of EQR
    Common.

    10.  EXCHANGE OF CERTIFICATES.

        (a) As of the Effective Time, EQR shall deposit, or shall cause to be
    deposited, with an exchange agent selected by EQR (the "Exchange Agent"),
    for the benefit of the holders of certificates evidencing shares of Lexford
    Common (the "Lexford Certificates"), for exchange in accordance with this
    Section 10, certificates evidencing the EQR Common (the "EQR Certificates")
    to be issued pursuant to this Section 10.

        (b) Promptly after the Effective Time, EQR shall cause the Exchange
    Agent to mail to each holder of record of Lexford Common a letter of
    transmittal which shall specify (i) that delivery shall be effected, and
    risk of loss and title to Lexford Certificates shall pass, only upon
    delivery of such Lexford Certificates to the Exchange Agent, and shall be in
    such form and have such other provisions as EQR may reasonably specify, and
    (ii) instructions for use in effecting the surrender of such Lexford
    Certificates in exchange for EQR Certificates and cash in lieu of fractional
    shares of EQR Common. Upon surrender of one or more Lexford Certificates for
    cancellation to the Exchange Agent, duly executed and completed in
    accordance with the instructions thereto, together with such letter of
    transmittal, the holder of such Lexford Certificates so surrendered shall be
    entitled to receive in exchange therefor (x) a EQR Certificate evidencing
    the number of

                                      B-3
<PAGE>
    whole shares of EQR Common and (y) a check representing the amount of cash
    in lieu of fractional shares of EQR Common, if any, and unpaid dividends and
    distributions, if any, which such holder has the right to receive pursuant
    to the provisions of Section 9(c) in respect of the one or more Lexford
    Certificates surrendered, after giving effect to any required withholding
    tax, and the one or more Lexford Certificates so surrendered shall forthwith
    be canceled. No interest will be paid or accrued on the cash in lieu of
    fractional shares of EQR Common and unpaid dividends and distributions, if
    any, payable to holders of Lexford Certificates. In the event of a transfer
    of ownership of Lexford Common which is not registered in the transfer
    records of Lexford, EQR Certificates evidencing the proper number of EQR
    Common, together with a check for the cash to be paid in lieu of any
    fractional shares of EQR Common, if any, and unpaid dividends and
    distributions, if any, which such holder has the right to receive pursuant
    to Section 9(c) in respect of the Lexford Certificate so surrendered, after
    giving effect to any required withholding tax, may be issued to such a
    transferee if the Lexford Certificate is presented to the Exchange Agent,
    accompanied by all documents required to evidence and effect such transfer
    and to evidence that any applicable share transfer taxes have been paid. All
    Lexford Certificates so surrendered will be canceled forthwith.
    Notwithstanding the foregoing, neither the Exchange Agent nor any party
    hereto shall be liable to a holder of Lexford Common for any EQR Common or
    dividends or other distributions thereon, or cash in lieu of any fractional
    EQR Common, delivered to a public official pursuant to applicable abandoned
    property, escheat or other applicable law.

        (c) Notwithstanding any other provisions of these Articles, no dividends
    or other distributions on EQR Common shall be paid with respect to any EQR
    Common evidenced by a Lexford Certificate until such Lexford Certificate is
    surrendered for exchange as provided herein. Subject to the effect of
    applicable laws, following surrender of any such Lexford Certificate, there
    shall be paid to the holder of the EQR Certificate issued in exchange
    therefor, without interest, (i) at the time of such surrender, the amount of
    dividends or other distributions with a record date after the Effective Time
    theretofore payable with respect to such whole shares of EQR Common and not
    paid, less the amount of any withholding taxes which may be required
    thereon, and (ii) at the appropriate payment date, the amount of dividends
    or other distributions with a record date after the Effective Time but prior
    to surrender and a payment date subsequent to surrender payable with respect
    to such whole shares of EQR Common, less the amount of any withholding taxes
    which may be required thereon. Any distribution payable with respect to
    Lexford Common with a record date prior to the Effective Time which shall
    not have been paid as of the Effective Time shall be paid to the holders
    entitled to such distribution whether or not such holders have surrendered
    their Lexford Certificates in accordance with the provisions hereof.

        (d) At and after the Effective Time, there shall be no transfers on the
    share transfer books of Lexford of the shares of Lexford Common which were
    outstanding immediately prior to the Effective Time. If, after the Effective
    Time, Lexford Certificates are presented to EQR, they shall be canceled and
    exchanged for certificates evidencing EQR Common and cash in lieu of
    fractional EQR Common, if any, and unpaid dividends and distributions
    deliverable in respect thereof pursuant to these Articles in accordance with
    the procedures set forth in this Section 10.

        (e) Any portion of the EQR Certificates made available to the Exchange
    Agent pursuant to Section 10(a) which remains unclaimed by the holders of
    Lexford Common for one hundred twenty (120) days after the Effective Time
    shall be delivered to EQR, upon demand of EQR, and any former shareholders
    of Lexford who have not theretofore complied with this Section 10 shall look
    only to EQR for payment of their EQR Common, cash in lieu of fractional
    shares of EQR Common and unpaid dividends and distributions on the EQR
    Common deliverable in respect of each share of Lexford Common such
    shareholder holds as determined pursuant to these Articles, in each case,
    without any interest thereon.

                                      B-4
<PAGE>
        (f) None of Lexford, EQR, the Exchange Agent or any other person shall
    be liable to any former holder of Lexford Common for any amount properly
    delivered to a public official pursuant to applicable abandoned property,
    escheat or similar laws.

        (g) In the event any Lexford Certificate shall have been lost, stolen or
    destroyed, upon the making of an affidavit of that fact by the person
    claiming such certificate to be lost, stolen or destroyed and, if required
    by EQR, the posting by such person of a bond in such reasonable amount as
    EQR may direct as indemnity against any claim that may be made against it
    with respect to such Lexford Certificate, the Exchange Agent or EQR will
    issue in exchange for such lost, stolen or destroyed Lexford Certificate the
    EQR Common and cash in lieu of fractional EQR Common, and unpaid dividends
    and distributions on the EQR Common as provided in Section 9(c), deliverable
    in respect thereof pursuant to these Articles.

    11.  NOTICE.  Any notice or other communication required or permitted under
these Articles shall be given, and shall be effective, in accordance with the
provisions of the Merger Agreement.

    12.  GOVERNING LAW.  These Articles shall be governed by and construed in
accordance with the laws of the State of Maryland.

    13.  COUNTERPARTS.  These Articles may be executed in multiple counterparts,

constitute one agreement.

    14.  ABANDONMENT.  The Merger may be abandoned before the Effective Time by
majority vote of the entire Board of Trustees of EQR and Board of Trustees of
Lexford.

    IN WITNESS WHEREOF, these Articles have been signed on this     day of
         , 1999 by the                    of EQR and the                    of

                  OPINION OF MORGAN STANLEY & CO. INCORPORATED

                                  [LETTERHEAD]

                                                      June 30, 1999

Board of Trustees
Lexford Residential Trust
The Huntington Center
41 South High Street
Suite 2410
Columbus, OH 43215

Members of the Board:

We understand that Lexford Residential Trust ("Lexford") and Equity Residential
Properties Trust ("Equity Residential") propose to enter into an Agreement and
Plan of Merger, substantially in the form of the draft dated as of June 30, 1999
(the "Merger Agreement"), which provides, among other things, for the merger
(the "Merger") of Lexford with and into Equity Residential with Equity
Residential as the surviving entity. Pursuant to the Merger, each outstanding
common share of beneficial interest of Lexford, par value $0.01 per share
("Lexford Common Shares"), other than Lexford Common Shares held in treasury or
any shares held by Equity Residential or any wholly-owned subsidiary of Equity
Residential, will be converted into the right to receive 0.463 common shares of
beneficial interest of Equity Residential, par value $0.01 per share of Equity
Residential ("Equity Residential Common Shares"). The terms and conditions of
the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the consideration to be received by
holders of Lexford Common Shares pursuant to the Merger Agreement is fair from a
financial point of view to such holders.

For purposes of the opinion set forth herein, we have, among other things:

     (i)      reviewed certain publicly available financial statements and other
             business and financial information of Lexford and Equity
             Residential, respectively;

     (ii)     reviewed certain internal financial statements and other financial
             and operating data concerning Lexford and Equity Residential
             prepared by the managements of Lexford and Equity Residential,
             respectively;

     (iii)     analyzed certain financial forecasts for Lexford and Equity
             Residential prepared by the managements of Lexford and Equity
             Residential, respectively;

     (iv)     discussed the past and current operations and financial condition
             and the prospects of Lexford and Equity Residential, including
             information relating to certain strategic, financial and
             operational benefits anticipated from the Merger, with senior
             executives of Lexford and Equity Residential, respectively;

     (v)     reviewed the pro forma impact of the Merger on Lexford's and Equity
             Residential's funds from operations per share, consolidated
             capitalization and financial ratios;

     (vi)     reviewed the reported prices and trading activity for the Lexford
             Common Shares and the Equity Residential Common Shares;

     (vii)    compared the financial performance of Equity Residential and the
             prices and trading activity of Equity Residential Common Shares
             with those of certain other comparable publicly-traded companies
             and their securities;

     (viii)    reviewed the financial terms, to the extent publicly available,
             of certain transactions deemed relevant;

     (ix)     discussed with senior executives of Lexford and Equity Residential
             their strategic objectives of the Merger and the plan for the
             combined company;

     (x)     participated in discussions and negotiations among representatives
             of Lexford, Equity Residential and certain other parties and their
             financial and legal advisors;

     (xi)     reviewed drafts of the Merger Agreement and certain related
             documents; and

     (xii)    performed such other analyses and considered such other factors as
             we have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy
and completeness of the information supplied or otherwise made available to us
by Lexford and Equity Residential for the purposes of this opinion. With respect
to the financial forecasts, we have assumed that they have been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the future financial performance of Lexford and Equity Residential.
Morgan Stanley relied upon, without independent verification, the assessment of
the managements of Lexford and Equity Residential of the strategic, financial
and operational benefits expected to result from the merger. We have not made
any independent valuation or appraisal of the assets or liabilities of Lexford
or Equity Residential, nor have we been furnished with any such appraisals. Our
opinion is necessarily based on financial, economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. In addition, we have assumed that the Merger will be treated as a
tax-free reorganization pursuant to the Internal Revenue Code of 1986 as
amended.

We have acted as financial advisor to the Board of Trustees of Lexford in
connection with this transaction and will receive a fee for our services, a
significant portion of which is contingent upon the consummation of the merger.
In addition, Lexford has agreed to indemnify us for certain liabilities arising
out of our engagement. In the ordinary course of our trading, brokerage and
financing activities, Morgan Stanley & Co. Incorporated or its affiliates may at
any time hold long or short positions, and may trade or otherwise effect
transactions, for our own account or the accounts of customers, in debt or
equity securities or senior loans for Lexford or Equity Residential.

It is understood that this letter is for the information of the Board of
Trustees of Lexford and may not be used for any other purpose without our prior
written consent, except that this opinion may be included in its entirety in any
filing made by Lexford with the Securities and Exchange Commission with respect
to the Merger. We express no opinion and make no recommendation as to how
shareholders of Lexford

should vote at the shareholders' meeting to be held in connection with the
Merger. In addition, we are not expressing any opinion herein as to the price at
which the Equity Residential Common Stock will trade following the announcement
or the consummation of the Merger.

Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the consideration to be received by the holders of Lexford Common
Shares pursuant to the Merger Agreement is fair from a financial point of view
to such holders.

                                          Very truly yours,

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF TRUSTEES AND OFFICERS

    Under Maryland law, a REIT organized in Maryland is permitted to eliminate,
by provision in its Declaration of Trust, the liability of its trustees,
officers and shareholders for money damages except for liability resulting from
(a) actual receipt of an improper benefit or profit in money, property or
services or (b) active and deliberate dishonesty established by final judgment
as being material to the cause of action. The Declaration of Trust of EQR
includes such a provision eliminating the liability of its trustees, officers
and shareholders to the maximum extent permitted by Maryland law.

    The Declaration of Trust of EQR authorizes it, to the maximum extent
permitted by Maryland law, to obligate itself to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceedings
to (a) any present or former shareholder, trustee or officer or (b) any
individual who, while a shareholder, trustee or officer of and at the request of
EQR, serves or has served another corporation, partnership, joint venture,
trust, employee benefit plan or any other enterprise as a trustee, director,
officer or partner of such corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise from and against any claim or
liability to which such person may become subject or which such person may incur
by reason of his status as a present or former trustee or officer of EQR. The
Bylaws of EQR obligate it, to the maximum extent permitted by Maryland law, to
indemnify and to pay or reimburse reasonable expenses in advance of final
disposition of a proceeding (a) any present or former trustee or officer who is
made a party to the proceeding by reason of his service in that capacity or (b)
any individual who, while a trustee or officer of EQR and at the request of EQR,
serves or has served another corporation, partnership, joint venture, trust,
employee benefit plan or any other enterprise as a trustee, director, officer or
partner of such corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise and who is made a party to the proceeding by reason of
his service in that capacity, against any claim or liability to which he may
become subject by reason of such status. The Declaration of Trust and Bylaws
also permit EQR to indemnify and advance expenses to any person who served a
predecessor of EQR in any of the capacities described above and to any employee
or agent of EQR or a predecessor of EQR. The Bylaws of EQR require it to
indemnify a trustee or officer who has been successful, on the merits or
otherwise, in the defense of any proceeding to which he is made a party by
reason of his service in that capacity.

    The Maryland REIT law permits a Maryland real estate investment trust to
indemnify and advance expenses to its trustees, officers, employees and agents
to the same extent as permitted by the Maryland General Corporation Law for
directors and officers of Maryland corporations. The Maryland General
Corporation Law permits a corporation to indemnify its present and former
directors and officers, among others, against judgments, penalties, fines,
settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made a party by reason of their service in
those or other capacities unless it is established that (a) the act or omission
of the director or officer was material to the matter giving rise to the
proceeding and (i) was committed in bad faith or (ii) was the result of active
and deliberate dishonesty, (b) the director or officer actually received an
improper personal benefit in money, property or services or (c) in the case of
any criminal proceeding, the director or officer had reasonable cause to believe
that the act or omission was unlawful. However, under the Maryland General
Corporation Law, a Maryland corporation may not indemnify for an adverse
judgment in a suit by or in the right of the corporation or for a judgment of
liability on the basis that personal benefit was improperly received, unless in
either case a court orders indemnification and then only for expenses. In
addition, the Maryland General Corporation Law permits a corporation to advance
reasonable expenses to a director or officer upon the corporation's

ITEM 20. INDEMNIFICATION OF TRUSTEES AND OFFICERS (CONTINUED)
receipt of (a) a written affirmation by the director or officer of his good
faith belief that he has met the standard of conduct necessary for
indemnification by the corporation and (b) a written undertaking by him or on
his behalf to repay the amount paid or reimbursed by the corporation if it shall
ultimately be determined that the standard of conduct was not met.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees and officers of EQR pursuant to the
foregoing provisions or otherwise, EQR has been advised that, although the
validity and scope of the governing statute have not been challenged in a court
of law, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable. In addition, indemnification may be
limited by state securities law.

ITEM 22. UNDERTAKINGS

    The undersigned registrant hereby undertakes:

       (1) (a) To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:

            (i) To include any prospectus required by Section 10(a)(3) of the
                Securities Act of 1933;

                                      II-2
<PAGE>
ITEM 22. UNDERTAKINGS (CONTINUED)
            (ii) To reflect in the prospectus any facts or events arising after
                 the effective date of the registration statement (or the most
                 recent post-effective amendment thereof) which, individually or
                 in the aggregate, represent a fundamental change in the
                 information set forth in the registration statement.
                 Notwithstanding the foregoing, any increase or decrease in the
                 volume of securities offered (if the total dollar value of
                 securities offered would not exceed that which was registered)
                 and any deviation from the low or high end of the estimated
                 maximum offering range may be reflected in the form of
                 prospectus filed with the Commission pursuant to Rule 424(b)
                 if, in the aggregate, the changes in volume and price represent
                 no more than a 20 percent change in the maximum aggregate
                 offering price set forth in the "Calculation of Registration
                 Fee" table in the effective registration statement;

           (iii) To include any material information with respect to the plan of
                 distribution not previously disclosed in the registration
                 statement or any material change to such information in the
                 registration statement.

       (b) That, for the purpose of determining any liability under the
           Securities Act of 1933, each such post-effective amendment shall be
           deemed to be a new registration statement relating to the securities
           offered therein, and the offering of such securities at that time
           shall be deemed to be the initial bona fide offering thereof.

       (c) To remove from registration by means of a post-effective amendment
           any of the securities being registered which remain unsold at the
           termination of the offering.

    (2) The undersigned registrant hereby undertakes that, for purposes of
       determining any liability under the Securities Act of 1933, each filing
       of the registrant's annual report pursuant to Section 13(a) or 15(d) of
       the Securities Exchange Act of 1934 (and, where applicable, each filing
       of an employee benefit plan's annual report pursuant to Section 15(d) of
       the Securities Exchange Act of 1934) that is incorporated by reference in
       the registration statement shall be deemed to be a new registration
       statement relating to the securities offered therein, and the offering of
       such securities at that time shall be deemed to be the initial bona fide
       offering thereof.

    (3) (a) The undersigned registrant hereby undertakes as follows: that prior
            to any public reoffering of the securities registered hereunder
            through use of a prospectus which is a part of this registration
            statement, by any person or party who is deemed to be an underwriter
            within the meaning of Rule 145(c), the issuer undertakes that such
            reoffering prospectus will contain the information called for by the
            applicable registration form with respect to reofferings by persons
            who may be deemed underwriters, in addition to the information
            called for by the other items of the applicable form.

       (b) The registrant undertakes that every prospectus (A) that is filed
           pursuant to paragraph (a) immediately preceding, or (B) that purports
           to meet the requirements of Section 10(a)(3) of the Act and is used
           in connection with an offering of securities subject to Rule 415,
           will be filed as part of an amendment to the registration statement
           and will not be used until such amendment is effective, and that, for
           purposes of determining any liability under the Securities Act of
           1933, each such post-effective amendment shall be deemed to be a new
           registration statement relating to the securities offered therein,
           and the offering of such securities at that time shall be deemed to
           be the initial bona fide offering thereof.

<PAGE>
ITEM 22. UNDERTAKINGS (CONTINUED)
    (4) Insofar as indemnification for liabilities arising under the Securities
       Act of 1933 may be permitted to directors, officers and controlling
       persons of the registrant pursuant to the foregoing provisions, or
       otherwise, the registrant has been advised that in the opinion of the
       Securities and Exchange Commission such indemnification is against public
       policy as expressed in the Act and is, therefore, unenforceable. In the
       event that a claim for indemnification against such liabilities (other
       than the payment by the registrant of expenses incurred or paid by a
       director, officer or controlling person of the registrant in the
       successful defense of any action, suit or proceeding) is asserted by such
       director, officer or controlling person in connection with the securities
       being registered, the registrant will, unless in the opinion of its
       counsel the matter has been settled by controlling precedent, submit to a
       court of appropriate jurisdiction the question whether such
       indemnification by it is against public policy as expressed in the Act
       and will be governed by the final adjudication of such issue.

    (5) The undersigned registrant hereby undertakes to respond to requests for
       information that is incorporated by reference into the prospectus
       pursuant to Item 4, 10(b), 11, or 13 of this form, within one business
       day of receipt of such request, and to send the incorporated documents by
       first class mail or other equally prompt means. This includes information
       contained in documents filed subsequent to the effective date of the
       registration statement through the date of responding to the request.

    (6) The undersigned registrant hereby undertakes to supply by means of a
       post-effective amendment all information concerning a transaction, and
       the company being acquired involved therein, that was not the subject of
       and included in the registration statement when it became effective.
