          This Amendment No. 2 hereby amends and supplements the Statement on
Schedule 13D filed by Meditrust on April 23, 1997, as amended by a filing made
on May 19, 1997 (the Schedule 13D as filed on April 23, 1997 being referred to
as the "Original 13D," and such Original 13D as amended by the filing made on
May 19, 1997 being referred to as the "Amended 13D"), in respect of the Common
Stock, par value $.10 per share of Santa Anita Realty Enterprises, Inc.
("Realty") and Santa Anita Operating Company ("Operating" and, together with
Realty, "Santa Anita").  This Amendment No. 2 is being filed, among other
reasons, to add Meditrust Acquisition Company, a Massachusetts business trust
and a wholly-owned subsidiary of Meditrust ("New MAC"), as a filing person to
the Amended 13D, to describe certain of the terms of the Second Amended and
Restated Agreement and Plan of Merger, dated as of April 13, 1997, between Santa
Anita, Meditrust, New MAC and Meditrust Acquisition Corporation IV ("MAC IV")
(the "Amended Merger Agreement") and to disclose New MAC's intention to purchase
in open-market transactions paired shares of the Common Stock, par value $.10
per share, of Santa Anita ("Paired Shares") representing up to 9.8% of the
issued and outstanding Paired Shares.

ITEM 2.  IDENTITY AND BACKGROUND

          Item 2 of the Amended 13D is hereby amended to include the following:

          (a)-(c) and (f) This statement is also being filed by New MAC, a
Massachusetts business trust.  The principal executive offices of New MAC are
located at 197 First Avenue, Needham Heights, Massachusetts 02194-9127.

          New MAC is a wholly-owned subsidiary of Meditrust formed in June 1997
for the purpose of merging with and into Operating pursuant to the terms of the
Amended Merger Agreement.

          David F. Benson is a Trustee and the President of New MAC.  Edward F.
Brooke is a Trustee of New MAC.  Michael S. Benjamin is the Secretary of New
MAC. The residence or business address and the principal occupation or
employment of each of Mr. Benson, Mr. Brooke and Mr. Benjamin, and the name and
principal business address of any corporation or other organization in which
such employment is conducted, is described on Schedule I of the Original 13D.

          (d) During the last five years, neither New MAC nor, to the best of
New MAC's knowledge, any of Mr. Benson, Mr. Brooke or Mr. Benjamin, has been
convicted in any criminal proceeding (excluding traffic violations or similar
misdemeanors).

          (e) During the last five years, neither New MAC nor, to the best of
New MAC's knowledge, any of Mr. Benson, Mr. Brooke or Mr. Benjamin, has been a
party to any civil proceeding of a judicial or administrative body of competent
jurisdiction as a result of which any of such persons was or is subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.

ITEM 3.   SOURCE AND USES OF FUNDS

          Item 3 of the Schedule 13D is hereby amended and restated in its
entirety as follows:

          Pursuant to the Amended Merger Agreement, New MAC has agreed to
purchase from Santa Anita, prior to the record date (the "Record Date") for the
Santa Anita shareholder meetings (the "Santa Anita Shareholder Meetings") to be
called for the purpose of approving the mergers (the "Mergers") contemplated by
the Amended Merger Agreement, at $31.00 per Paired Share, such number of Paired
Shares that would result in New MAC and Meditrust owning, in the aggregate,
pursuant to the constructive ownership rules of the Internal Revenue Code, 9.8%
of the number of Paired Shares that will be issued and outstanding immediately
after the consummation of such purchase (the "New MAC Purchase"), taking into
account the number of Paired Shares held by New MAC and/or Meditrust immediately
prior to the consummation of the MAC Purchase. /1/

          In addition, pursuant to the Amended Merger Agreement, Meditrust may
designate New MAC and/or one or more unaffiliated persons who may purchase,
prior to the Record Date, from Santa Anita, at $31.00 per Paired Share, up to
such number of Paired Shares, in the aggregate, that is equal to 19.6% of the
issued and outstanding Paired Shares immediately prior to the consummation of
the New MAC Purchase,/2/ less the number of Paired Shares purchased by New MAC
from Santa Anita pursuant to the New MAC Purchase;/3/ provided that in no event
may New MAC or any unaffiliated person designated by Meditrust purchase a number
of such Paired Shares which would result in it owning, pursuant to the
constructive ownership rules of the Internal Revenue Code, in excess of 9.8% of
the issued and outstanding Paired Shares.



- ----------
/1/   Based on there being 11,460,664 Paired Shares issued and outstanding as of
      June 10, 1997, 1,245,171 Paired Shares would be required to be purchased
      by New MAC from Santa Anita pursuant to the New MAC Purchase, assuming no
      Paired Shares are held by New MAC or Meditrust immediately prior to the
      consummation of the New MAC Purchase. For each Paired Share held by New
      MAC or Meditrust immediately prior to the consummation of the New MAC
      Purchase, New MAC's obligation to purchase Paired Shares pursuant to the
      New MAC Purchase will be reduced by approximately 1.11 Paired Shares.


/2/   Based on there being 11,460,664 Paired Shares issued and outstanding as of
      June 10, 1997, 19.6% of the currently issued and outstanding Paired Shares
      would represent approximately 2,246,290 Paired Shares.

/3/   Assuming New MAC purchases from Santa Anita 1,245,171 Paired Shares
      pursuant to the New MAC Purchase, 1,001,119 Paired Shares would be
      available for purchase by New MAC and/or one or more unaffiliated persons
      designated by Meditrust. For each Paired Share held by New MAC or
      Meditrust immediately prior to the consummation of the New MAC Purchase,
      the number of Paired Shares available for purchase by New MAC or one or
      more unaffiliated persons designated by Meditrust will be increased by
      approximately 1.11 Paired Shares.

                                 Page 5 of 11
<PAGE>
 
          Pursuant to the Amended Merger Agreement, Meditrust is obligated to
transfer to New MAC approximately $43,589,036./4/  Meditrust intends to transfer
such funds from its working capital.  Purchases of Paired Shares by New MAC are
intended to be financed with such funds.

ITEM 4.   PURPOSE OF TRANSACTION

          Item 4 of the Amended 13D is hereby amended and restated in its
entirety as follows:

          On June 19, 1997, Santa Anita, Meditrust, MAC IV and New MAC entered
into the Amended Merger Agreement pursuant to which, among other things, (a) a
novation was effected to release MAC IV from its obligations under the Merger
Agreement (as defined in the Original 13D) and to substitute New MAC in its
place, (b) prior to the record date for the shareholder meetings of Meditrust
and New MAC to be called for the purpose of approving the Mergers, Meditrust
will distribute to its shareholders the beneficial ownership of all of the New
MAC shares of beneficial interests without par value ("New MAC Shares") and (c)
Meditrust will be merged into Realty, New MAC will be merged in the Operating,
and each holder of  Meditrust shares of beneficial interests without par value
("Meditrust Shares") and New MAC Shares will be entitled to receive in a tax-
free exchange 1.2016 Paired Shares for each Meditrust Share and New MAC Share
owned by such holder.  Upon completion of the Mergers, the surviving
corporations will be called Meditrust Corporation and Meditrust Operating
Company, respectively.

          As more fully described in Item 3 above, pursuant to the Amended
Merger Agreement, New MAC has agreed to purchase from Santa Anita, prior to the
Record Date, at $31.00 per Paired Share, a number of Paired Shares, and
Meditrust may designate New MAC and/or one or more unaffiliated persons who may,
prior to the Record Date, purchase from Santa Anita, at $31.00 per Paired Share,
a number of Paired Shares.

          The Amended Merger Agreement also provides that, if requested by Santa
Anita, Meditrust and New MAC will ensure that $100 million, less the aggregate
purchase price of the Paired Shares purchased from Santa Anita by New MAC and
unaffiliated persons designated by Meditrust pursuant to the Amended Merger
Agreement, is made available to fund, at $31.00 per Paired Share, a cash
election in connection with the Mergers for Paired Shares outstanding prior to
the Mergers.  In no event shall the $100 million required to be made available
be reduced, by reason of purchases of Paired Shares by New MAC and unaffiliated
persons designated by 



- ----------
/4/   Pursuant to the Amended Merger Agreement, Meditrust is obligated to
      transfer to New MAC, immediately prior to the record date for the
      shareholder meetings of Meditrust and New MAC to be called for the purpose
      of approving the Mergers, an amount of cash equal to .019 multiplied by
      the product of $37.25 times the number of Meditrust Shares (as defined in
      Item 4) outstanding immediately prior to the time at which such transfer
      is effected. Based upon there being 61,588,182 Meditrust Shares issued and
      outstanding as of June 17, 1997 such amount would be equal to
      approximately $43,589,036.

                                 Page 6 of 11
<PAGE>
 
Meditrust, by an amount in excess of the product of $31.00 and the number of
Paired Shares that would be required to be purchased by New MAC pursuant to the
New MAC Purchase if no Paired Shares were held by MAC or Meditrust immediately
prior to the consummation of the New MAC Purchase./5/

          Upon consummation of the Mergers, up to twelve directors designated by
Meditrust will serve on the Boards of Directors of Meditrust Corporation and
Meditrust Operating Company, the surviving entities.  Meditrust Corporation's
Board of Directors will include two current members of the Board of Directors of
Realty, and Meditrust Operating Company's Board of Directors will include two
current members of the Board of Directors of Operating.

          In connection with the Mergers, the Certificates of Incorporation of
Realty and Operating will be amended to increase each of their authorized
capital stock to 306,000,000 shares of which 300,000,000 shares will be common
stock and 6,000,000 shares will be preferred stock.  Of the 300,000,000 shares
of common stock that will be authorized by the Certificates of Incorporation of
Realty and Operating, 19,000,000 of such shares will be designated as Common
Stock, par value $10 per share, and the remaining 281,000,000 of such shares
will be designated as a new class of common stock ("Series Common Stock").  The
Board of Directors of Meditrust Corporation and Meditrust Operating Company
would have the right to authorize the issuance of the shares of Series Common
Stock in one or more series with such designations, preferences, rights,
qualifications and restrictions with respect to matters such as voting,
dividends, conversion rights etc. as such Boards of Directors may determine in
their sole discretion, without any further authorization by shareholders.
Although they have no present intention to do so, the Boards of Directors of
Meditrust Corporation and Meditrust Operating Company could authorize the
issuance of one or more series of Series Common Stock that could, depending on
the terms of the series in which issued, make more difficult or discourage an
attempt to obtain control of such corporations by means of a merger, tender
offer, proxy contest or otherwise.

          Pursuant to the terms of the Amended Merger Agreement, following the
Mergers, Meditrust Corporation and Meditrust Operating Company will be
authorized to transfer some or all of their assets to one or more wholly-owned
subsidiaries in exchange for equity interests in such subsidiaries.

          Upon completion of the Mergers, Meditrust Corporation expects to
distribute dividends of at least 95% of its annual REIT taxable income in order
to maintain its status as a real estate investment trust under the Internal
Revenue Code.

          The Amended Merger Agreement and the Mergers contemplated thereby,
which have been approved unanimously by the Board of Trustees of Meditrust, the
Board of Trustees of 



- ----------
/5/   Assuming New MAC would be required to purchase 1,245,171 Paired Shares
      pursuant to the New MAC Purchase (see footnote 1), the maximum amount by
      which such $100 million could be reduced would be approximately
      $38,600,301.

                                 Page 7 of 11

New MAC and the Boards of Directors of Santa Anita, are subject to the approval
of the shareholders of Meditrust, New MAC and Santa Anita.

          The Amended Merger Agreement is attached hereto as Exhibit 1 and
incorporated herein by reference in its entirety.  The foregoing summary of the
Amended Merger Agreement does not purport to be complete and is qualified in its
entirety by reference to such exhibit.

          In addition, in view of expressions of interest from third-parties and
in furtherance of Meditrust's and New MAC's business objectives, officers and
representatives of Meditrust and New MAC have contacted, made specific proposals
to, and engaged in discussions with, and intend to continue to contact, make
specific proposals to, and engage in discussions with, third-parties from time
to time, and may from time to time conduct negotiations with third-parties,
regarding possible transactions, including acquisitions, joint ventures,
strategic alliances and other business arrangements, between Meditrust and/or
New MAC and these parties. Any such transaction would be conditioned on the
consummation of the Mergers.

          Officers and representatives of Meditrust and New MAC also have
contacted, responded to inquiries of, and engaged in discussions with, and
intend to continue to contact, respond to inquiries of, and engage in
discussions with, third-parties from time to time regarding the possibility of
one or more of these parties purchasing Paired Shares from Santa Anita pursuant
to Meditrust's right under the Amended Merger Agreement to designate
unaffiliated persons to purchase Paired Shares and/or purchasing Meditrust
Shares and/or New MAC Shares from Meditrust or New MAC, as applicable.

          There can, of course, be no assurance that any of the contacts,
discussions or negotiations described in the prior two paragraphs will result in
any transactions.

          New MAC intends, from time to time prior to the Record Date, to
purchase in open-market transactions, in privately negotiated transactions or
otherwise Paired Shares representing up to 9.8% of the issued and outstanding
Paired Shares.  The amounts of any such purchases will depend on prevailing
market conditions as well as the price and other terms of possible transactions.
At any time, prior to the Record Date, New MAC may, temporarily or permanently,
discontinue such purchases.

          Except as set forth in this Item 4 or the Amended Merger Agreement,
neither Meditrust, New MAC nor, to the best of Meditrust's and New MAC's
knowledge, any of the individuals named in Schedule I of the Original 13D, has
any plans or proposals which relate to or which would result in any of the
actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

          Item 5 of the Amended 13D is hereby amended and restated in its
entirety as follows:

          (a)-(b)  By reason of their execution of the Amended Merger Agreement
and New MAC's obligation to consummate the New MAC Purchase as described in Item
3, pursuant to Rule 13d-3(d)(1)(i) promulgated under the Securities Exchange Act
of 1934, as amended, Meditrust and New MAC may be each deemed to beneficially
own 1,245,171, shares of the

to such record dates, MAC shall purchase from Realty and Operating newly
issued, fully paid and nonassessable Santa Anita Shares at a purchase price of
$31.00 per Santa Anita Share (the "Acquired Shares"). With respect to any such
purchase, MAC shall for all purposes be deemed to have become the holder of
record of the number of Santa Anita Shares to be purchased immediately upon
delivery to Realty and Operating of written notice from MAC of its intention to
make such purchase and payment of the aggregate purchase price as provided in
clause (ii) below and delivery of the certificate in clause (iii) below. The
Santa Anita Share Certificates issued pursuant to this Section 1.6 shall have
impressed on, printed on, written on or otherwise attached to them the legend
set forth in Section 3(c) of the Rights Agreement and MAC shall have all the
rights to which a holder of Rights as of the Rights Record Date (as defined in
the Rights Agreement) is entitled. The number of Acquired Shares shall equal
such number of Santa Anita Shares that will result, immediately after the
issuance and sale of the Acquired Shares and after taking into account any
Santa Anita Shares purchased by Meditrust and MAC in the open market, in (a)
Meditrust or MAC owning, after application of the Constructive Ownership Rules
(as defined in the certificate described in clause (iii) below), 9.8% of the
outstanding Santa Anita Shares and (b) no other person owning, after
application of such Constructive Ownership Rules, in excess of 9.8% of the
outstanding Santa Anita Shares. To consummate the purchase of the Acquired
Shares and as a condition to their issuance, (i) Realty and Operating will have
delivered to MAC certificates representing the Acquired Shares, (ii) MAC will
have paid to Realty and Operating the aggregate purchase price for the Acquired
Shares in immediately available funds, (iii) MAC shall have delivered to Realty
and Operating a certificate in the form attached hereto as Annex B, (iv) the
Acquired Shares will have been approved for listing on the Exchange upon
official notice of issuance, and (v) O'Melveny & Myers LLP will have delivered
to MAC an opinion to the effect that the Acquired Shares have been duly
authorized by all necessary corporate action on the part of the issuer and that
the Acquired Shares are validly issued, fully paid and nonassessable. In the
event that this Agreement is terminated pursuant to Article VIII, MAC shall be
entitled to the benefit of the registration rights set forth in Annex D hereto
with respect to the Acquired Shares.
 
  Section 1.7: Sale of Santa Anita Shares to Designee of Meditrust. Prior to
the record date for the Realty and Operating shareholder meetings provided for
in Section 6.4.2, Meditrust may designate MAC and/or one or more Unaffiliated
Persons who may, prior to such record date, purchase from Realty and Operating
newly issued, fully paid and nonassessable Santa Anita Shares at a purchase
price of $31.00 per Santa Anita Share (the "Unaffiliated Acquired Shares").
With respect to any such purchase, MAC and/or the designated Unaffiliated
Person or Unaffiliated Persons shall for all purposes be deemed to have become
the holder or holders of record of the number of Santa Anita Shares to be
purchased immediately upon delivery to Realty and Operating of written notice
from Meditrust of such purchaser's or purchasers' intention to make such
purchase and payment of the aggregate purchase price as provided in clause (ii)
below and delivery of the certificate in clause (iii) below. The Santa Anita
Share Certificates issued pursuant to this Section 1.6 shall have impressed on,
printed on, written on or otherwise attached to them the legend set forth in
Section 3(c) of the Rights Agreement and the holder or holders of such shares
shall have all the rights to which a holder of Rights as of the Rights Record
Date (as defined in the Rights Agreement) is entitled. The aggregate number of
Unaffiliated Acquired Shares which may be purchased pursuant to this Section
1.7 is up to (a) 19.6% of the issued and outstanding Santa Anita Shares
immediately prior to the issuance and sale of the Acquired Shares to MAC
pursuant to Section 1.6 less (b) the number of Acquired Shares to be issued to
MAC pursuant to Section 1.6; provided, however, that no person, as a result of
the issuance and sale of the Unaffiliated Acquired Shares, shall own, after
application of the Constructive Ownership Rules, in excess of 9.8% of the
outstanding Santa Anita Shares. To consummate the purchase of the Unaffiliated
Acquired Shares and as a condition to their issuance, (i) Realty and Operating
will have delivered to the purchasers certificates representing the
Unaffiliated
 
                                      A-3
<PAGE>
 
Acquired Shares, (ii) such purchasers will have paid to Realty and Operating
the purchase price for the Unaffiliated Acquired Shares in immediately
available funds, (iii) such purchasers will have delivered to Realty and
Operating a certificate in the form attached hereto as Annex B if such
purchaser is MAC or in the form attached hereto as Annex C if such purchaser
is an Unaffiliated Purchaser, (iv) the Unaffiliated Acquired Shares will have
been approved for listing on the Exchange upon official notice of issuance,
and (v) O'Melveny & Myers LLP will have delivered to such purchasers an
opinion to the effect that such Unaffiliated Acquired Shares have been duly
authorized by all necessary corporate action on the part of the issuer and
that such Acquired Shares are validly issued, fully paid and nonassessable. In
the event that this Agreement is terminated pursuant to Article VIII or upon
the effectiveness of the Mergers, such purchasers who are Unaffiliated Persons
shall be entitled to the benefit of the registration rights set forth in Annex
D hereto with respect to the Unaffiliated Acquired Shares. In the event that
this Agreement is terminated pursuant to Article VIII and such purchaser is
MAC, MAC shall be entitled to the benefit of the registration rights set forth
in Annex D hereto with respect to the Unaffiliated Acquired Shares.
 
  Section 1.8: Assurance by Meditrust. At the option of the Realty Board and
the Operating Board, subject to and concurrent with the consummation of the
Mergers, Meditrust and MAC will ensure that Realty and Operating have
available in the aggregate up to $100,000,000 in cash in immediately available
funds, in the ratio of $98,900,000 for Realty and $1,100,000 for Operating, to
fund a cash election effective immediately after consummation of the Mergers
by the holders of Santa Anita Shares outstanding prior to the Mergers at
$31.00 per Santa Anita Share; provided that the sum of any amounts provided by
Meditrust and MAC shall be reduced by the purchase price paid (i) by MAC for
the Acquired Shares pursuant to Section 1.6, (ii) by MAC for the Unaffiliated
Acquired Shares pursuant to Section 1.7 and (iii) by Unaffiliated Purchasers
for the Unaffiliated Acquired Shares pursuant to Section 1.7; provided further
that in no event shall the sum of any such amounts provided by Meditrust and
MAC be reduced by an amount in excess of $31.00 multiplied by such number that
would represent the number of Acquired Shares that would be required to be
purchased by MAC pursuant to Section 1.6 if immediately prior to such purchase
MAC owned, pursuant to the Constructive Ownership Rules, no Santa Anita
Shares. Such funds shall be provided to Realty and Operating after the
delivery by Operating to Realty of the promissory note referred to in Section
1.1.2 and immediately after the consummation of the Mergers.
 
  Section 1.9: Transfer of Assets. Following the Mergers, the Surviving
Corporations may, and are hereby authorized to, transfer some or all of their
assets to one or more wholly-owned subsidiaries in exchange for all of the
equity interests in such subsidiaries. Such subsidiaries may issue additional
equity interests to the Surviving Corporations or to unaffiliated Persons on
such terms as the governing boards of such subsidiaries shall determine.

                MERGER CONSIDERATION; ASSIGNMENT CONSIDERATION;
              CONVERSION OR CANCELLATION OF SHARES IN THE MERGERS
 
  Section 4.1: Realty Merger Consideration; Conversion or Cancellation of
Meditrust Shares. At the Effective Time, by virtue of the Realty Merger and
without any action on the part of the holder of any capital stock of
Meditrust, subject to Sections 4.4 and 4.5, each Meditrust Share issued and
outstanding immediately prior to the Effective Time (other than any Meditrust
Share held in Meditrust's treasury (which shall be cancelled)) will be
converted into the right to receive such number of fully paid and
nonassessable Realty Common Shares as may be calculated in accordance with the
Exchange Ratio. Realty Shares outstanding immediately prior to the Effective
Time shall remain outstanding after the Effective Time and shall not be
converted or exchanged in the Realty Merger, except that any Realty Shares
held by MAC may be cancelled at the option of Operating Surviving Corporation.
 
  Section 4.2: Operating Merger Consideration; Conversion or Cancellation of
MAC Shares. At the Effective Time, by virtue of the Operating Merger and
without any action on the part of the holder of any capital stock of MAC,
subject to Sections 4.4 and 4.5, each MAC Share issued and outstanding
immediately prior to the Effective Time (other than any MAC Share held in
MAC's or Meditrust's treasury (which shall be cancelled)) will be converted
into the right to receive such number of fully paid and nonassessable
Operating Shares as may be calculated in accordance with the Exchange Ratio.
Operating Shares outstanding immediately prior to the Effective Time shall
remain outstanding after the Effective Time and shall not be converted or
exchanged in the Operating Merger, except that any Operating Shares held by
MAC shall be cancelled.
 
  Section 4.3: Exchange Ratio. The number of Realty Common Shares into which
each Meditrust Share will be converted, as provided in Section 4.1, and the
number of Operating Common Shares into which each MAC Share will be converted,
as provided in Section 4.2, will be equal to the number obtained by dividing
(i) $37.25, by (ii) the sum of (x) $31.00 and (y) if the Closing Date occurs
after December 31, 1997, as a result of acquisitions and other business
combinations proposed to be entered into by Meditrust or MAC (and provided
that there are no other conditions to closing within Realty's or Operating's
control or for which they are responsible that have not yet been satisfied), a
number equal to the per share amount of any dividends of
 
                                      A-5
<PAGE>
 
Meditrust, if any, accrued with respect to periods after such date and prior
to the Closing Date divided by 1.2016 less the per share amount of any
dividends of Realty accrued with respect to periods after such date and prior
to the Closing Date (the "Exchange Ratio").
 
  Section 4.4: Pairing of Realty and Operating Shares. Pursuant to the Pairing
Agreement, each and every Realty Share issued in connection with the Realty
Merger will be paired with an Operating Share issued in connection with the
Operating Merger, with the effect that each Meditrust shareholder will receive
paired shares of common stock of Realty Surviving Corporation and Operating
Surviving Corporation.
 
  Section 4.5: Exchange of Old Certificates for New Certificates.
 
    4.5.1 Effect on Meditrust Shares and MAC Shares.
 
      (a) At the Effective Time, all Meditrust Shares and MAC Shares will
    cease to be outstanding, will be cancelled and retired and will cease
    to exist, and each holder of an Old Meditrust Certificate will
    thereafter cease to have any rights with respect to such Old Meditrust
    Certificates, except the right to receive, without interest, upon
    exchange of such Old Meditrust Certificates in accordance with this
    Section 4.5, the Santa Anita Share Certificates and payments to which
    such holder is entitled pursuant to this Article IV. A holder of an Old
    Meditrust Certificate shall have no rights as a shareholder of Realty
    or Operating until the Old Meditrust Certificate have been exchanged
    for Santa Anita Share Certificates and cash as provided herein.
 
      (b) Notwithstanding anything contained in this Agreement to the
    contrary, in order for Realty Surviving Corporation to continue to meet
    the REIT Requirements, no person or entity shall own, or be deemed to
    own by virtue of the attribution provisions of Section 544 (as modified
    by Section 856(h)(1)(B)) or Section 318 (as modified by Section
    856(d)(5)) of the Code, more than 9.8% of the outstanding Santa Anita
    Shares (the "Ownership Limit") at or after the Effective Time.
    Therefore, if any holder of Meditrust Shares or MAC Shares would
    receive in connection with the Mergers a number of Santa Anita Shares
    such that any person or entity would own, or be deemed to own under the
    applicable attribution rules of the Code referred to above, Santa Anita
    Shares in excess of the Ownership Limit, then such holder shall acquire
    no right or interest in such number of Santa Anita Shares which would
    cause such person or entity to exceed the Ownership Limit, but such
    holder shall, in lieu of receiving those Santa Anita Shares which would
    cause the Ownership Limit to be exceeded (the "Limited Shares"), have
    the right to be paid by Realty Surviving Corporation an amount in cash
    for such Limited Shares equal to the product of the Fair Market Value
    (as hereinafter defined) per Limited Share multiplied by the number of
    such Limited Shares. "Fair Market Value" shall be equal to the average
    closing price of the Santa Anita Shares on the Exchange on the five (5)
    trading days immediately preceding the Effective Time.
 
    4.5.2 Appointment of Exchange Agent. From and after the Effective Time
  until the end of the six-month period following the Effective Time, the
  Surviving Corporations will make available or cause to be made available to
  an exchange agent appointed by Meditrust and reasonably acceptable to
  Realty and Operating (the "Exchange Agent"), certificates for (a) paired
  Realty and Operating Common Shares (the "Santa Anita Share Certificates"),
  and (b) cash in amounts sufficient to allow the Exchange Agent to make all
  deliveries of Santa Anita Share Certificates and payments that may be
  required in exchange for Old Meditrust Certificates pursuant to this
  Article IV.
 
    4.5.3 Exchange Procedures. Promptly after the Effective Time, the
  Surviving Corporations will cause the Exchange Agent to mail or deliver to
  each person who was, at the Effective Time, a holder of record of Meditrust
  Shares a form (the terms of which will be mutually agreed upon by the
  parties hereto prior to the Effective Time) of letter of transmittal
  containing instructions for use in effecting the surrender of the Old
  Meditrust Certificates in exchange for Santa Anita Share Certificates and
  payments pursuant to this Article IV. Upon surrender to the Exchange Agent
  of an Old Meditrust Certificate for cancellation together with such letter
  of transmittal, duly executed and completed in accordance with the
  instructions thereto, the holder of such Old Meditrust Certificate will be
  entitled to receive in exchange therefor a Santa Anita Share Certificate
  representing paired shares of the Surviving Corporations, to which such
 
                                      A-6
<PAGE>
 
  holder is entitled pursuant to this Article IV, and the Old Meditrust
  Certificate shall be cancelled. No interest will be paid or will accrue on
  the amount payable upon surrender of Old Meditrust Certificates. If any
  Santa Anita Share Certificate is to be issued in a name other than that in
  which the Old Meditrust Certificate surrendered in exchange therefor is
  registered, it will be a condition of such exchange that the person
  requesting such exchange will pay any transfer or other taxes required by
  reason of the issuance of such Santa Anita Share Certificate in a name
  other than that of the registered holder of the Old Meditrust Certificate
  surrendered, or will establish to the satisfaction of the Surviving
  Corporations that any such taxes have been paid or are not applicable. Six
  months after the Effective Time, the Surviving Corporations will be
  entitled to cause the Exchange Agent to deliver to them any applicable
  Santa Anita Share Certificates, or cash (including any interest thereon)
  made available to the Exchange Agent that are unclaimed by the former
  shareholders of Meditrust and MAC. Any such former shareholders who have
  not theretofore exchanged their Old Meditrust Certificates for Santa Anita
  Share Certificates and cash pursuant to this Article IV will thereafter be
  entitled to look exclusively to the Surviving Corporations and only as
  general creditors thereof for the Santa Anita Shares and cash to which they
  become entitled upon exchange of their Old Meditrust Certificates pursuant
  to this Article IV. Each Surviving Corporation will pay all applicable
  charges and expenses, including its applicable share of those of the
  Exchange Agent, in connection with the exchange of Santa Anita Share
  Certificates and cash as contemplated hereby.
 
    4.5.4 Fractional Shares. No fractional Santa Anita Shares will be issued
  in the Reorganization. In lieu of any such fractional shares, each person
  who would otherwise have been entitled to a fraction of a Santa Anita Share
  upon surrender of an Old Meditrust Certificate pursuant to this Article IV
  will be paid an amount in cash (without interest) equal to such holder's
  proportionate interest in the net proceeds from the sale or sales in the
  open market by the Exchange Agent, on behalf of all such holders, of the
  aggregate fractional Santa Anita Shares which would otherwise be issued
  pursuant to this Article IV. As soon as practicable following the Effective
  Time, the Exchange Agent will determine the excess of (i) the number of
  full Santa Anita Shares delivered to the Exchange Agent over (ii) the
  aggregate number of full Santa Anita Shares to be distributed in respect of
  Meditrust Shares and MAC Shares (such excess being herein called the
  "Excess Shares"), and the Exchange Agent, as agent for the former holders
  of such shares, will sell the Excess Shares at the prevailing prices on the
  open market. The sale of the Excess Shares by the Exchange Agent will be
  executed on the Exchange through one or more firms and will be executed in
  round lots to the extent practicable. All commissions, transfer taxes and
  other out-of-pocket transaction costs, including the expenses and
  compensation of the Exchange Agent, incurred in connection with such sale
  of Excess Shares, will be deducted from the proceeds from the sale of the
  Excess Shares. Until the earlier of six months following the Effective Time
  and the date the net proceeds of such sale or sales have been distributed,
  the Exchange Agent will hold such proceeds in trust for such former
  shareholders. As soon as practicable after the determination of the amount
  of cash to be paid in lieu of any fractional interests, the Exchange Agent
  will make available in accordance with this Agreement such amounts to such
  former shareholders.
 
    4.5.5 Distributions with Respect to Unexchanged Shares. Notwithstanding
  any other provisions of this Agreement, as provided in Section 4.5.1, no
  holder of an Old Meditrust Certificate shall have rights as a shareholder
  of Realty or Operating until such holder has exchanged its Old Meditrust
  Certificate for a Santa Anita Share Certificate; therefore, no dividends
  will be paid to any person holding an Old Meditrust Certificate until such
  Old Meditrust Certificate is surrendered for exchange as provided herein
  (it being understood that such dividends will be paid to the Exchange Agent
  to be held for distribution upon the exchange for Old Meditrust
  Certificates as herein provided). Subject to the effect of applicable laws,
  following surrender of any such Old Meditrust Certificate by any holder
  thereof, there will be paid to the holder of the Santa Anita Share
  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
  the Santa Anita Shares represented thereby 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 the time of such
  surrender and a payment date subsequent to the time of such surrender
  payable with respect
 
                                      A-7
<PAGE>
 
  to the Santa Anita Shares represented thereby, less the amount of any
  withholding taxes which may be required thereon.
 
    4.5.6 Transfers. At or after the Effective Time, there will be no
  transfers on the stock transfer books of either Surviving Corporation of
  Meditrust Shares or MAC Shares which were outstanding immediately prior to
  the Effective Time.
 
    4.5.7 No Liability. In the event that any Old Meditrust Certificate is
  lost, stolen or destroyed, upon the making of an affidavit of that fact by
  the person claiming such Old Meditrust Certificate to be lost, stolen or
  destroyed and, if required by the Surviving Corporations, the posting by
  such person of a bond in such reasonable amount as the Surviving
  Corporations may direct as indemnity against any claim that may be made
  against it with respect to such Old Meditrust Certificate, the Surviving
  Corporations will, in exchange for such lost, stolen or destroyed Old
  Meditrust Certificates, issue or cause to be issued the Santa Anita Shares
  and pay or cause to be paid the amounts deliverable in respect thereof
  pursuant to this Article IV. None of any party hereto, the Exchange Agent
  or either Surviving Corporation will be liable to any holder of Meditrust
  Shares or MAC Shares for any cash, Santa Anita Shares or other property
  from the payment fund delivered to a public official pursuant to any
  applicable abandoned property, escheat or similar law.
 
    4.5.8 Withholding Rights. The Surviving Corporations will be entitled to
  deduct and withhold from the consideration otherwise payable pursuant to
  this Agreement to any holder of Meditrust Shares or MAC Shares such amounts
  as may be required to be deducted and withheld with respect to the making
  of such payment under the Code, or under any provision of state or local
  tax law. To the extent that amounts are so withheld and paid over to the
  appropriate taxing authority, such withheld amounts will be treated for all
  purposes of this Agreement as having been paid to the holder of the
  Meditrust Shares in respect of which such deduction and withholding was
  made.
 
    4.5.9 Transfer Taxes. Except as provided above, the Surviving
  Corporations will pay or cause to be paid any transfer or gains tax
  (including, without limitation, any real property gains or transfer tax)
  imposed in connection with or as a result of the Mergers, including any
  such tax that is imposed on a shareholder of Meditrust.
 
    4.5.10 Stock Options.
 
      (a) As soon as practicable following the date of this Agreement, the
    Meditrust Board (or, if appropriate, any committee administering the
    Stock Plans (as defined below)) shall adopt such resolutions or take
    other actions as may be required to effect the following:
 
        (i) adjust the terms of all outstanding employee stock options to
      purchase Meditrust Shares ("Employee Stock Options") granted under
      Meditrust's equity incentive plans (collectively, the "Stock
      Plans"), to provide that, at the Effective Time, each Employee Stock
      Option outstanding immediately prior to the Effective Time shall be
      deemed to constitute an option to acquire, on the same terms and
      conditions as were applicable under such Employee Stock Option, the
      same number of Realty Shares as the holder of such Employee Stock
      Option would have been entitled to receive pursuant to the Realty
      Merger had such holder exercised such Employee Stock Option in full
      immediately prior to the Effective Time at a price per share equal
      to (y) the aggregate exercise price for the Meditrust Shares
      otherwise purchasable pursuant to such Employee Stock Option divided
      by (z) the number of Realty Common Shares deemed purchasable
      pursuant to such Employee Stock Option; provided, however, that in
      the case of any option to which Section 421 of the Code applies by
      reason of its qualification under any of Sections 422-424 of the
      Code ("qualified stock options"), the option price, the number of
      Realty Shares purchasable pursuant to such option and the terms and
      conditions of exercise of such option shall be determined in order
      to comply with Section 424(a) of the Code; and
 
        (ii) make such other changes to the Stock Plans as it deems
      appropriate to give effect to the Mergers (subject to the approval
      of Realty and Operating, which shall not be unreasonably withheld).
 
                                      A-8
<PAGE>
 
    No Employee Stock Options will be issued for Operating Common Shares. No
  Employee Stock Options granted pursuant to the Stock Plans shall be
  exercisable unless the holder submits evidence satisfactory to Realty that,
  at the then fair market value of an unpaired share of Operating Common
  Share as determined pursuant to the Pairing Agreement, a number of
  Operating Common Shares equal to the number of Realty Common Shares to be
  received upon exercise of all or a portion of the Employee Stock Option
  will, and are able to be, purchased by the holder, such that upon exercise
  the holder will acquire an equal number of Realty Common Shares and
  Operating Common Shares.
 
    (b) As soon as practicable after the Effective Time, Realty shall deliver
  to the holders of Employee Stock Options appropriate notices setting forth
  such holders' rights pursuant to the respective Stock Plans and the
  agreements evidencing the grants of such Employee Stock Options shall
  continue in effect on the same terms and conditions (subject to the
  adjustments required by this Section 4.5.10 after giving effect to the
  Mergers). Realty shall comply with the terms of the Stock Plans and ensure,
  to the extent required by, and subject to the provisions of, such Stock
  Plans, that the Employee Stock Options which qualified as qualified stock
  options prior to the Effective Time continue to qualify as qualified stock
  options after the Effective Time.
 
    (c) Realty and Operating shall take all corporate action necessary to
  reserve for issuance a sufficient number of Realty Common Shares for
  delivery upon exercise of the Employee Stock Options and Operating Common
  Shares for delivery upon purchase as provided in clause (a) above assumed
  in accordance with this Section 4.5.10. The Surviving Corporations shall
  use their reasonable best efforts to have declared effective as soon as
  practicable following the Effective Time, a registration statement on Form
  S-8 (or any successor or other appropriate form) with respect to the Santa
  Anita Shares subject to such Employee Stock Options and shall use their
  reasonable best efforts to maintain the effectiveness of such registration
  statement or registration statements (and maintain the current status of
  the prospectus or prospectuses contained therein) for so long as such
  Employee Stock Options remain outstanding. With respect to those
  individuals who subsequent to the Mergers will be subject to the reporting
  requirements under Section 16(a) of the Exchange Act, where applicable, the
  Surviving Corporations shall administer the Stock Plans assumed pursuant to
  this Section 4.5.10 in a manner that complies with Rule 16b-3 promulgated
  under the Exchange Act to the extent the applicable Stock Plan complied
  with such rule prior to the Mergers.

  Section 5.1: Representations and Warranties of Meditrust.
 
  As an inducement to Realty and Operating to enter into this Agreement and to
consummate the transactions contemplated hereby, Meditrust represents and
warrants to Realty and Operating and agrees as follows:
 
    5.1.1 Organization of Meditrust. Meditrust is a business trust duly
  organized, validly existing and in good standing under the laws of the
  Commonwealth of Massachusetts. Meditrust is duly qualified to transact
  business and is in good standing in each of the jurisdictions in which the
  ownership or leasing of the properties used in its business or the conduct
  of its business requires such qualification (each of which is listed in the
  Meditrust Disclosure Schedule), other than in such jurisdictions where the
  failure to be so qualified and in good standing would not, individually or
  in the aggregate, have a Material Adverse Effect on Meditrust. Meditrust
  has all requisite power and authority to own or lease and operate its
  properties and to carry on its business as now conducted. Meditrust has
  delivered to Realty and Operating complete and correct copies of the
  Restated Declaration of Trust and By-laws of Meditrust (the "Meditrust
  Charter") as amended and in effect on the date hereof. Meditrust has no
  subsidiaries other than as set forth in the Meditrust Disclosure Schedule.

  which is a corporation, its name, the jurisdiction of its incorporation,
  the number of shares of its capital stock of each class outstanding and the
  number of such outstanding shares owned by Meditrust and its other
  subsidiaries and (b) as to each subsidiary of Meditrust which is not a
  corporation, its name, the jurisdiction of its organization or formation
  and a detailed description of its capital structure which indicates the
  direct or indirect interest of Meditrust in such subsidiary. Each of the
  subsidiaries of Meditrust and MAC is a trust, corporation, limited
  liability company or partnership duly organized, validly existing and in
  good standing under the laws of the jurisdiction of its formation and has
  all requisite power and authority to own or lease and operate its
  properties, and to carry on its business as now conducted. All of the
  issued and outstanding shares of capital stock or other equity interests in
  each subsidiary of Meditrust are validly issued, fully paid and
  nonassessable and owned beneficially by Meditrust, free and clear of any
  liens or other encumbrances, and there are no options, warrants or other
  rights to acquire, or agreements or commitments pursuant to which any such
  subsidiary is obligated to issue, sell, purchase or redeem shares of
  capital stock or other equity interests in such subsidiary. Immediately
  prior to the Effective Time, all of the issued and outstanding MAC Shares
  will be validly issued, fully paid and nonassessable.

  Meditrust consists of an unlimited number of shares of beneficial interest
  without par value (the "Meditrust Shares"), of which 61,495,104 Meditrust

      (a) At all times since January 1, 1980, Realty has been and will
    continue to be organized and operated in conformity with the REIT
    Requirements, and its proposed method of operation will enable it to

    federal income tax status of its paired share status. The Pairing
    Agreement was duly and validly authorized and is a valid and binding
    agreement, enforceable against Realty in accordance with its terms. The

    Pairing Agreement and such pairing is grandfathered from the
    application of Section 269B(a)(3) of the Code pursuant to Section
    136(c)(3) of the Deficit Reduction Act of 1984.
 
      (b)  The execution or delivery by Realty of this Agreement and the
    consummation by Realty of the transactions contemplated hereby or
    compliance with or fulfillment of the terms and provisions hereof by
    Realty, will not (i) conflict with the private letter rulings issued by
    the IRS to Realty dated October 16, 1979 and January 11, 1980 (the
    "Private Letter Rulings") or (ii) adversely affect the qualification of
    Realty as a REIT, for each taxable year ending on or after the date of
    this Agreement or adversely affect the ability of Realty to retain its
    status as grandfathered from the application of Section 269B(a)(3) of
    the Code pursuant to Section 136(c)(3) of the Deficit Reduction Act of
    1984.

    timely, completely and correctly filed all Federal, state and local tax
    returns and reports required to be filed by them, and has timely, paid

    required to be paid with respect thereto, except where the failure to
    file or pay is not reasonably expected to have a Material Adverse
    Effect on Realty. Except as set forth in the Realty Disclosure
    Schedule, neither Realty nor any of its subsidiaries have been audited
    or examined by the IRS or any state or local taxing authority and no
    notice of any such audit has been received by Realty, nor has Realty
    extended any applicable statute of limitations for the assessment or
    collections of tax. Except as disclosed in the Realty Disclosure
    Schedule, no liens for taxes exist with respect to any assets or
    properties of Realty or any of its subsidiaries, except for statutory

    regulations relating to the payment and withholding of taxes (including
    without limitations, withholding of taxes pursuant to Sections 1441,

    federal laws or any state or local laws, domestic or foreign) and has,
    within the time and the manner prescribed by law, withheld from and
    paid over to the proper governmental authorities all amounts required
    to be so withheld and paid over under applicable laws, except where the

    Material Adverse Effect on Realty.

    policy (written or oral) relating to stock options, stock purchases,

    other employee benefits, in each case maintained or contributed to, or
    required to be maintained or contributed to, by Realty for the benefit
    of any present or former employee, officer or director (each of the
    foregoing, a "Benefit Plan") has been administered in all material
    respects in accordance with its terms. Realty and all their Benefit
    Plans are in compliance with the applicable provisions of ERISA, all
    other applicable laws and all applicable collective bargaining
    agreements, except where the failure to comply would not reasonably be
    expected to have a Material Adverse Effect on Realty.
 
      (b) None of Realty or any Commonly Controlled Entity has incurred any
    liability to a Pension Plan under Title IV of ERISA (other than for
    contributions or liabilities under Section 412 of the Code not yet due)
    or to the Pension Benefit Guaranty Corporation (other than for payment
    of premiums not yet due) that, when aggregated with other such
    liabilities, would result in a material liability of Realty, which
    liability has not been fully paid.

    employee of Realty or any of its subsidiaries will be entitled to any
    additional benefits or any acceleration of the time of payment or
    vesting of any benefits under any Benefit Plan as a result of the
    transactions contemplated by this Agreement.

    of the Code has received a favorable determination letter from the IRS
    that covers the Tax Reform Act of 1986.

warrants to Meditrust and MAC and agrees as follows:
 
    5.3.1 Organization of Operating. Operating is a corporation duly
  incorporated, validly existing and in good standing under the laws of the
  State of Delaware. Operating and its subsidiaries are each duly qualified
  to transact business and are each in good standing in each of the
  jurisdictions in which the ownership or leasing of the properties used in
  its business or the conduct of its business requires such qualification
  (each of which is listed in the Operating Disclosure Schedule), other than
  in such jurisdictions where the failure to be so qualified and in good
  standing would not, individually or in the aggregate, have a Material
  Adverse Effect on Operating. Operating has all requisite corporate power
  and authority to own or lease and operate its properties and to carry on
  its business as now conducted. Operating has delivered to Meditrust
  complete and correct copies of the Certificate of Incorporation (the
  "Operating Certificate") and by-laws (the "Operating By-laws") of
  Operating, in each case as amended and in effect on the date hereof.
 
    5.3.2 Operating Subsidiaries. The Operating Disclosure Schedule
  accurately and completely sets forth as to (a) each subsidiary of Operating
  which is a corporation, its name, the jurisdiction of its incorporation,
  the number of shares of its capital stock of each class outstanding and the
  number of such outstanding shares owned by Operating and its other
  subsidiaries and (b) as to each subsidiary of Operating which is not a
  corporation, its name, the jurisdiction of its organization or formation
  and a detailed description of its capital structure which indicates the
  direct or indirect interest of Operating in such subsidiary. Each
  subsidiary of Operating is a trust, corporation, limited liability company
  or partnership duly organized, validly existing and in good standing under
  the laws of the jurisdiction of its formation and has all requisite power
  and authority to own or lease and operate its properties, and to carry on
  its business as now conducted. All of the issued and outstanding shares of
  capital stock or other equity interests in each subsidiary of Operating are
  validly issued, fully paid and nonassessable and owned beneficially by
  Operating, free and clear of any liens or other encumbrances, and there are
  no options, warrants or other rights to acquire, or agreements or
  commitments pursuant to which any such subsidiary is obligated to issue,
  sell, purchase or redeem shares of capital stock or other equity interests
  in such subsidiary.
 
                                     A-18

    5.3.3 Capitalization. On the date hereof, the authorized capital of
  Operating consists of 6,000,000 shares of preferred stock, $.10 par value
  (the "Operating Preferred Shares"), and 19,000,000 shares of common stock,
  $.10 par value (the "Operating Common Shares" and together with the
  Operating Preferred Shares, the "Operating Shares"), of which 867,343
  Operating Preferred Shares and 11,496,225 Operating Common Shares are
  validly issued and outstanding and are fully paid and nonassessable and of
  which none is reserved for any purpose, except those Operating Shares
  issuable upon exercise of the Operating Options (as hereinafter defined),
  the exchange of outstanding Operating Preferred Shares and the Rights.
  Operating has granted options to purchase an aggregate of 470,000 Operating
  Common Shares (the "Operating Options") pursuant to option plans of
  Operating. Except for the Operating Options, and except as contemplated by
  this Agreement or as disclosed in the Operating Disclosure Schedule, there
  are no options, warrants or other rights to acquire, or agreements or
  commitments pursuant to which Operating is obligated to issue, sell,
  purchase or redeem shares of capital stock of Operating. 59,291 restricted
  Operating Common Shares have been issued pursuant to Operating's 1995 Share
  Award Plan. The Acquired Shares and the Unaffiliated Acquired Shares have
  been duly authorized and when issued and paid for in accordance with the
  terms of this Agreement, will be fully paid and nonassessable Santa Anita
  Shares, not subject to any preemptive right.
 
    5.3.4 Authority.

    provisions of, or constitute a default, an event of default or an event
    creating rights of acceleration, termination or cancellation or a loss
    of rights, or result in the creation or imposition of any encumbrance
    upon any of the assets of Operating or any of its subsidiaries, under

    activities of Operating to be attributed to Realty as provided in
    Section 269B(a)(3) of the Code.

    scheduled repayments pursuant to the terms of such indebtedness;
 
      (j) amend or terminate the Rights Agreement unless advised by outside

  Section 6.2: Acquisition Proposals. (a) From the date of this Agreement
until the Closing Date, neither Realty nor Operating nor any of their
respective subsidiaries will, and each of Realty and Operating will use their
best efforts to cause their respective directors and any other persons acting,
or purporting to act, on their behalf (including, but not limited to, their
officers, employees, investment bankers, financial advisors, attorneys or
accountants) not to, initiate any contact with, solicit, encourage or enter
into or continue any discussions, negotiations, understandings or agreements
with, anyone other than Meditrust (a "Third Party") with respect to, or
furnish or disclose any non-public information regarding Realty, Operating or
their subsidiaries, to any Third Party in connection with, any Competing
Transaction Proposal. Notwithstanding the foregoing, to the extent the Realty
Board and the Operating Board could reasonably be required by their fiduciary
duties as determined in good faith on the written advice of outside counsel to
Realty and Operating, to take the following steps at any time prior to
approval by the Realty shareholders of the Realty Shareholder Matters and
approval by the Operating shareholders of the Operating Shareholder Matters,
(i) Realty and Operating may, in response to an unsolicited request, furnish
non-public information with respect to Realty and Operating or their
subsidiaries to any Third Party pursuant to a customary confidentiality and
standstill agreement and discuss that information (but not a Competing
Transaction Proposal) with the Third Party and (ii) upon receipt by Realty or
Operating of a Competing Transaction Proposal from a Third Party, if each of
the Realty Board and the Operating Board has reasonably determined that the
transaction contemplated by the Competing Transaction Proposal, if
consummated, would constitute an Alternative Transaction, then Realty and
Operating may participate in discussions and negotiations with the Third Party
regarding the Competing Transaction Proposal.
 
  (b) At least five business days prior to entering into definitive agreements
with respect to an Alternative Transaction, Realty and Operating will deliver
an Alternative Transaction Notice to Meditrust advising it of the
determination by the Realty Board and the Operating Board that the transaction
contemplated by the Competing Transaction Proposal would constitute an
Alternative Transaction, which notice will include a summary of the
Alternative Transaction. During such five business day period, Meditrust may
propose an improved transaction to Realty and Operating.
 
  (c) If prior to the approval by the shareholders of Realty of the Realty
Shareholder Matters and approval by the shareholders of Operating of the
Operating Shareholder Matters (i) Realty and Operating have delivered an
Alternative Transaction Notice to Meditrust in accordance with Section 6.2(b),
(ii) the terms of the Alternative Transaction are not modified in a manner
adverse to Realty or Operating and (iii) Realty and Operating have paid the
Termination Fee to Meditrust and reimbursed Meditrust's Transaction Expenses,
then Realty and Operating may terminate this Agreement and enter into an
agreement with a Qualified Third Party with respect to the Alternative
Transaction described in the Alternative Transaction Notice that Realty and
Operating gave to Meditrust. A "Qualified Third Party" means a Third Party
which the Board of Directors of Realty and Operating reasonably determine has
the financial ability (including, to the extent external financing will be
required, binding commitments for that financing) to complete an Alternative
Transaction.
 
  (d) Neither Realty nor Operating will modify, or release any third party
from, any confidentiality or standstill agreement to which either of them is a
party.

  Section 6.3: Information Supplied. Each of the parties hereto agrees that
none of the information supplied or to be supplied by it for inclusion or
incorporation by reference in any registration statement, proxy statement or
Schedule 14A, or any amendment or supplement thereto, will, in the case of a
registration statement, at the time such registration statement and each
amendment and supplement thereto becomes effective under the Securities Act,
or, in the case of a proxy statement or Schedule 14A, at the time such proxy
statement or Schedule 14A and each amendment and supplement thereto is filed
with the SEC or mailed to shareholders and at the time of the applicable
meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein not misleading.
 
  Section 6.4: Shareholder Approvals; Registration Statement.
 
    6.4.1 Registration Statement. Realty, Operating, Meditrust and MAC shall
  prepare and file with the SEC the Registration Statement registering the
  issuance of the Santa Anita Shares to Meditrust's and MAC's shareholders,
  which shall include a joint proxy statement to solicit proxies in
  connection with the meetings of the shareholders of each of Realty,
  Operating, Meditrust and MAC referred to in Section 6.4.2 (the form of such
  joint proxy statement, together with any amendments thereof or supplements
  thereto, mailed to the shareholders of each of Realty, Operating, Meditrust
  and MAC in connection with such meetings is referred to herein as the
  "Proxy Statement").
 
    6.4.2 Shareholder Meetings. Subject to the second succeeding sentence,
  each of Realty, Operating, Meditrust and MAC agrees to take, in accordance
  with applicable law and its Certificate of Incorporation and By-laws or
  Charter, all action necessary to convene a meeting of its respective
  shareholders, as promptly as practicable after the Proxy Statement is
  cleared by the SEC, to consider and vote upon the approval of the
  transactions contemplated hereby. Subject to the next succeeding sentence,
  each of the Realty Board, the Operating Board, the Meditrust Board and the
  Board of Trustees of MAC shall recommend such adoption and approval and
  shall take all lawful action to solicit such approval by shareholders. Each
  of the Realty Board or the Operating Board may fail to take action
  necessary to convene a meeting of its shareholders or make such a
  recommendation, or withdraw, modify, or change any such recommendation, or
  recommend any other offer or proposal, only if Realty and Operating have
  complied with Section 6.2(a) and an Alternative Transaction is pending at
  the time the Realty Board and Operating Board make such determination;
  provided that no such failure to convene a meeting or to recommend, or no
  such withdrawal, modification or change of any such recommendation or
  recommendation of any other offer or proposal shall be made unless (a)
  Realty and Operating shall have delivered to Meditrust at least 48 hours
  written notice advising Meditrust that the Boards of Realty and Operating
  have received a proposal for an Alternative Transaction and identifying the
  person or persons making such proposal and (b) such Board, based on the
  written opinion of its outside counsel, has determined that convening such
  a meeting, making such recommendation, or the failure to recommend any
  other offer or proposal, or the failure to so withdraw, modify, or change
  its recommendation, or the failure to recommend any other offer or
  proposal, could reasonably be deemed to cause the members of such board to
  breach their fiduciary duties under applicable law. In such event,
  notwithstanding anything contained in this Agreement to the contrary, any
  such failure to convene such a meeting, failure to recommend, withdrawal,
  modification, or change of recommendation or recommendation of such other
  offer or proposal, or the entering by Realty and Operating into an
  agreement with respect to an Alternative Transaction in accordance with
  Section 6.2, shall not constitute a breach of this Agreement by Realty and
  Operating. Neither Meditrust nor MAC shall be required to convene its
  shareholder meeting if Realty and Operating do not convene their respective
  shareholder meetings as described in this Section 6.4.2.
 
  Section 6.5: Other Actions.
 
    6.5.1 Each party hereto shall cooperate with the other parties hereto,

  shall use reasonable best efforts to resolve any objections that may be
  asserted with respect to the Reorganization by the Department of Justice,
  the Federal Trade Commission, any State Attorney General or any other
  Governmental Entity (including, without limitation, objections under any
  antitrust laws). In the event a suit is threatened or instituted
  challenging the Reorganization as violative of any antitrust laws, each
  party shall use reasonable efforts to avoid the filing of, resist or
  resolve such suit. The parties hereto shall use reasonable efforts to take
  such action as may be required: (i) by the Department of Justice, the
  Federal Trade Commission, any State Attorney General or any other
  Governmental Entity in order to resolve such objections as any of them may
  have to the Reorganization, or (ii) by any federal or state court of the
  United States, in any suit brought by a private party or Governmental
  Entity challenging the Reorganization as violative of any antitrust laws,
  in order to avoid the entry of, or to cause the withdrawal or voiding of,
  any injunction, temporary restraining order or other order which has the
  effect of preventing the consummation of the transactions contemplated
  hereby.

Realty and Operating further agrees to treat Meditrust as a shareholder of
such company and to afford to Meditrust all rights to which Meditrust would be

respective subsidiaries (collectively, the "Indemnified Parties") as provided
in the Realty Certificate or Realty By-laws and the Operating Certificate or
Operating By-laws or pursuant to other agreements, as in effect as of the date
hereof, shall survive the Closing and shall continue in full force and effect.
Each of Realty Surviving Corporation and Operating Surviving Corporation shall
maintain in effect for not less than six years the current policies (or
comparable policies) of directors' and officers' liability insurance
maintained by Realty and Operating with respect to matters occurring prior to
the Closing Date; provided however, that if the aggregate annual premiums for
such insurance during such six year period shall exceed 200% of the per annum
rate of the aggregate premium currently paid by Operating and Realty and any
of their respective subsidiaries for such insurance on the date of this
Agreement, then Meditrust shall cause each of Realty Surviving Corporation and
Operating Surviving Corporation to, and each of Realty Surviving Corporation
and Operating Surviving Corporation shall, provide the most advantageous
coverage that shall then be available at an annual premium equal to 200% of
such rate. This Section 6.9 is intended to benefit the Indemnified Parties.
 
  Section 6.10: Colony Termination Fee. Realty and Operating have paid to
Colony $4,500,000 as a termination fee and transaction expenses pursuant to
the Amended and Restated Formation Agreement, dated as of October 24, 1996, as
amended as of January 7, 1997. If either Meditrust or MAC fail to call their
respective shareholders meetings or the shareholders fail to approve the
Meditrust Shareholder Matters or the MAC Shareholder Matters at their
respective shareholder meetings, and the Realty Shareholder Matters and the
Operating Shareholder Matters are approved and all other conditions to
Meditrust's consummation of the Reorganization have been satisfied, Meditrust
shall pay to Realty and Operating $4,000,000 in the aggregate; provided,
however, that if Realty determines, in its sole and absolute discretion, that
its portion of such amount will affect its qualification as a REIT, then the
parties will negotiate in good faith an arrangement acceptable to Realty. In
no event shall such payment be less than the lower of (a) the maximum amount
which Realty may receive without affecting its qualification as a REIT and (b)
the amount to be paid pursuant to this Section 6.10 without regard to this
sentence.

  Section 8.2: Termination by any Party Hereto. This Agreement may be
terminated, and the Reorganization may be abandoned before or after the
approval by the shareholders of Meditrust, MAC, Operating and/or Realty, by
action of the Board of any party hereto, if (i) the Reorganization shall not
have been consummated by April 13, 1998 or (ii) if Meditrust, Realty,
Operating or MAC convene the shareholders meeting contemplated by Section 6.4

Realty or Operating shall have failed to comply in any material respect with
any of the covenants or agreements contained herein to be performed by such
Company at or prior to the time of termination; or (ii) either of the Realty
Board or the Operating Board shall have failed to recommend to its

  the actuarial interest of such beneficiaries (provided, however, that in
  the case of a "grantor trust" the Ownership Interest will be considered as
  owned by the grantors);
 
    (4) if 10 percent or more in value of the stock in a corporation is
  owned, directly or constructively, by or for any person, such person shall

  stock in such corporation;
 
    (5) an Ownership Interest that is owned, directly or constructively, by
  or for a partner of a partnership or a beneficiary of an estate or trust
  shall be considered as owned by the partnership, estate, or trust;
 
    (6) if 10 percent or more in value of the stock in a corporation is

  reason of the application of the rules described in paragraphs (1) through
  (7) above shall, for purposes of applying paragraphs (1) through (7), be
  considered as directly owned by such person provided, however, that (a) an
  Ownership Interest constructively owned by an individual by reason of
  paragraph (1) shall not be considered as owned by him for purposes of again
  applying paragraph (1) in order to make another the constructive owner of
  such Ownership Interest, (b) an Ownership Interest constructively owned by
  a partnership, estate, trust, or corporation by reason of the application
  of paragraphs (5) or (6) shall not be considered as owned by it for
  purposes of applying paragraphs (2), (3), or (4) in order to make another
  the constructive owner of such Ownership Interest, (c) if an Ownership
  Interest may be considered as owned by an individual under paragraphs (1)
  or (7), it shall be considered as owned by him under paragraph (7), and (d)
  for purposes of the above described rules, an S corporation shall be
  treated as a partnership and any shareholder of the S corporation shall be
  treated as a partner of such partnership except that this rule shall not
  apply for purposes of determining whether stock in the S corporation is
  constructively owned by any person.
 
    (9) For purposes of the above summary of the constructive ownership
  rules, the term "Ownership Interest" means the ownership of stock with
  respect to a corporation and, with respect to any other type of entity, the
  ownership of an interest in either its assets or net profits.

  2.3. Following receipt of a request for a registration pursuant to Section
2.1, Realty and Operating shall:
 
    (i) File the registration statement with the Commission as promptly as
  practicable and shall use their respective reasonable efforts to have the
  registration declared effective under the Securities Act as soon as
  reasonably practicable, in each instance giving due regard to the need to
  prepare current financial statements, conduct due diligence and complete
  other actions that are reasonably necessary to effect a registered public
  offering.
 
    (ii) Use their respective reasonable efforts to keep the relevant
  registration statement Continuously Effective until such date as of which
  all the Registrable Securities under the registration statement have been
  disposed of in a manner described in the registration statement, but in no
  event later than the 120th day following the effective date of such
  registration statement. Notwithstanding the foregoing, if for any reason
  the effectiveness of a registration pursuant to this Section 2 is
  suspended, the relevant foregoing period shall be extended by the aggregate
  number of days of such suspension.
 
  2.4. Notwithstanding anything in this Agreement to the contrary, no
registration shall be effected hereunder and no Transfer of Registrable
Securities may be effected if as a result thereof Realty would not satisfy the
REIT Requirements in any respect or if such registration or Transfer would
result in any Person Beneficially Owning Paired Shares in excess of the
Ownership Limit. For purposes of the preceding sentence, registration shall
not be deemed to have been effected (i) unless a registration statement with
respect thereto has become effective, or (ii) if after such registration
statement has become effective, the related offer, sale or distribution of
Registrable Securities thereunder is prohibited by any stop order, injunction
or other order or requirement of the Commission or other governmental agency
or court for any reason not attributable to MT and such prohibition is not
thereafter eliminated. If Realty and Operating shall have complied with their
respective obligations under this Agreement, a right to demand a registration
pursuant to this Section 2 shall be deemed to have been satisfied upon the
effective date of the registration statement, provided no stop order or
similar order, or proceedings for such an order, is thereafter entered or
initiated.
 
  2.5. A registration pursuant to this Section 2 shall be on such appropriate
registration form of the Commission as shall be selected by Realty and
Operating and shall permit the disposition of the Registrable Securities in
accordance with the intended method or methods of disposition specified in the
request pursuant to Section 2.1.
 
  2.6. If the registration pursuant to Section 2 involves an underwritten
offering (whether on a "firm commitment," "best efforts" or "all reasonable
efforts" basis or otherwise), MT shall select the underwriter or underwriters
and manager or managers to administer such underwritten offering; provided,
however, that each Person so selected shall be acceptable to Realty and
Operating.
 
  Section 3. Registration Procedures. Whenever required under Section 2 to
effect the registration of any Registrable Securities, Realty and Operating
shall, as expeditiously as practicable:
 
  3.1. Prepare and file with the Commission a registration statement with
respect to such Registrable Securities and use their respective reasonable
efforts to cause such registration statement to become effective; provided,
however, that before filing a registration statement or prospectus or any
amendments or supplements thereto, Realty and Operating shall furnish to one
firm of counsel for MT copies of all such documents in the form substantially
as proposed to be filed with the Commission.
 
  3.2. Prepare and file with the Commission such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of
the Securities Act and rules thereunder with respect to the disposition of all
securities covered by such registration statement. Realty and Operating shall
amend the registration statement or supplement the prospectus so that it will
remain current and in compliance with the requirements of the Securities Act
for the period specified in Section 2.3(ii), and if during such period any
event or development occurs as a result of which the registration statement or
prospectus contains a misstatement of a material fact or
 
                                     A-49
<PAGE>
 
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, Realty or Operating shall promptly
notify MT, amend the registration statement or supplement the prospectus so
that each will thereafter comply with the Securities Act and furnish to MT
such amended or supplemented prospectus, which MT shall thereafter use in the
Transfer of Registrable Securities covered by such registration statement.
Pending any such amendment or supplement, MT shall cease making offers or
Transfers of Registrable Shares pursuant to the prior prospectus. In the event
that any Registrable Securities included in a registration statement subject
to, or required by, this Agreement remain unsold at the end of the period
during which Realty and Operating are obligated to use their respective
reasonable efforts to maintain the effectiveness of such registration
statement, Realty and Operating may file a post-effective amendment to the
registration statement for the purpose of removing such Registrable Securities
from registered status.
 
  3.3. Furnish to MT without charge, such numbers of copies of the
registration statement, any pre-effective or post-effective amendment thereto,
the prospectus, including each preliminary prospectus and any amendments or
supplements thereto, in each case in conformity with the requirements of the
Securities Act and the rules thereunder, and such other related documents as
MT may reasonably request in order to facilitate the disposition of
Registrable Securities owned by MT.
 
  3.4. Use their respective reasonable efforts (i) to register and qualify the
securities covered by such registration statement under such other securities
or Blue Sky laws of such states where an exemption from registration is not
available and as shall be reasonably requested by the Underwriters'
Representative and (ii) to obtain the withdrawal of any order suspending the
effectiveness of a registration statement, or the lifting of any suspension of
the qualification (or exemption from qualification) of the offer and transfer
of any of the Registrable Securities in any state, at the earliest possible
moment; provided, however, that neither Realty nor Operating shall be required
in connection therewith or as a condition thereto to qualify to do business or
to consent to general service of process in any state.
 
  3.5. In the event of any underwritten offering, use their respective
reasonable efforts to enter into and perform their respective obligations
under an underwriting agreement (including indemnification and contribution
obligations of underwriters), in usual and customary form, with the managing
underwriter or underwriters of such offering. Realty and Operating shall also
cooperate with MT and the Underwriters' Representative for such offering in
the marketing of the Registrable Securities, including making available the
officers, accountants, counsel, premises, books and records of Realty and
Operating for such purpose, but neither Realty nor Operating shall be required
to incur any material out-of-pocket expense pursuant to this sentence.
 
  3.6. Promptly notify MT of any stop order issued or threatened to be issued
by the Commission in connection therewith and take all reasonable actions
required to prevent the entry of such stop order or to remove it if entered.
 
  3.7. Make available for inspection by MT, any underwriter participating in
such offering and the representatives of MT and such Underwriter (but not more
than one firm of counsel to MT), all financial and other information as shall
be reasonably requested by them, and provide MT, any underwriter participating
in such offering and the representatives of MT and such Underwriter the
reasonable opportunity to discuss the business affairs of Realty and Operating
with their principal executives and independent public accountants who have
certified the audited financial statements included in such registration
statement, in each case all as necessary to enable them to exercise their due
diligence responsibility under the Securities Act; provided, however, that
information that Realty or Operating determines to be confidential and which
Realty or Operating advises such Person in writing, is confidential shall not
be disclosed unless such Person signs a confidentiality agreement reasonably
satisfactory to Realty and Operating or MT agrees to be responsible for such
Person's breach of confidentiality on terms reasonably satisfactory to Realty
and Operating.
 
  3.8. Use their respective reasonable efforts to obtain a so-called "comfort
letter" from the independent public accountants of Realty and Operating, and
legal opinions of counsel to Realty and Operating addressed to
 
                                     A-50
<PAGE>
 
MT in customary form and covering such matters of the type customarily covered
by such letters, and in a form that shall be reasonably satisfactory to MT.
Delivery of any such opinion or comfort letter shall be subject to the
recipient furnishing such written representations or acknowledgements as are
customarily provided by selling stockholders who receive such comfort letters
or opinions.
 
  3.9. Use their respective reasonable efforts to cause the Registrable
Securities covered by such registration statement (i) if the Paired Shares are
then listed on a securities exchange or included for quotation in a recognized
trading market, to continue to be so listed or included for a reasonable
period of time after the offering, and (ii) to be registered with or approved
by such other United States or state governmental agencies or authorities as
may be necessary by virtue of the business and operations of Realty and
Operating to enable MT to consummate the disposition of such Registrable
Securities.
 
  3.10. Take such other actions as are reasonably required in order to
expedite or facilitate the disposition of Registrable Securities included in
each such registration.
 
  Section 4. MT's Obligations. It shall be a condition precedent to the
obligations of Realty and Operating to take any action pursuant to this
Agreement with respect to the Registrable Securities of MT that MT shall:
 
  4.1. Furnish to Realty and Operating such information regarding MT, the
number of the Registrable Securities owned by it, and the intended method of
disposition of such securities as shall be required to effect the registration
of MT's Registrable Securities, and to cooperate fully with Realty and
Operating in preparing such registration.
 
  Section 5. Expenses of Registration. Expenses in connection with
registrations pursuant to this Agreement shall be allocated and paid as
follows:
 
  5.1. Realty and Operating shall bear and pay all expenses incurred in
connection with any registration, filing, or qualification of Registrable
Securities, including all registration, filing and National Association of
Securities Dealers, Inc. fees, all fees and expenses of complying with
securities or blue sky laws, all printing expenses, messenger and delivery
expenses, the reasonable fees and disbursements of counsel for Realty and
Operating, and of the independent public accountants for Realty and Operating,
including the expenses of "cold comfort" letters required by or incident to
such performance and compliance (the "Registration Expenses"), but excluding
underwriting discounts and commissions relating to Registrable Securities
(which shall be paid by MT) and all fees and expenses of counsel for MT;
provided, however, that Realty and Operating shall not be required to pay for
any expenses of any registration proceeding begun pursuant to Section 2 if the
registration is subsequently withdrawn. Realty and Operating each agree
between themselves that they shall bear and pay Registration Expenses in an
amount equal to its respective Issuance Percentage of such Registration
Expenses and that they shall reimburse each other to the extent necessary to
cause each of them to so bear and pay such respective amounts.
 
  Section 6. Indemnification; Contribution. If any Registrable Securities are
included in a registration statement under this Agreement:
 
  6.1. To the extent permitted by applicable law, each of Realty and
Operating, severally and not jointly, shall indemnify and hold harmless MT,
each Person, if any, who controls MT within the meaning of the Securities Act,
and each officer, director, partner and employee of MT and such controlling
Person, against any and all losses, claims, damages, liabilities and expenses
(joint or several), including reasonable attorneys' fees and disbursements and
reasonable expenses of investigation, incurred by such party pursuant to any
actual or threatened action, suit, proceeding or investigation, or to which
any of the foregoing Persons may otherwise become subject under the Securities
Act, the Exchange Act or other federal or state laws, insofar as such losses,
claims, damages, liabilities and expenses arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"):
 
                                     A-51
<PAGE>
 
    (i) Any untrue statement or alleged untrue statement of a material fact
  contained in such registration statement, including any preliminary
  prospectus or final prospectus contained therein, or any amendments or
  supplements thereto; or
 
    (ii) The omission or alleged omission to state therein a material fact
  required to be stated therein, or necessary to make the statements therein
  not misleading; provided, however, that the indemnification required by
  this Section 6.1 shall not apply to amounts paid in settlement of any such
  loss, claim, damage, liability or expense if such settlement is effected
  without the consent of Realty or Operating (which consent shall not be
  unreasonably withheld), nor shall Realty or Operating be liable in any such
  case for any such loss, claim, damage, liability or expense to the extent
  that it arises out of or is based upon a Violation which occurs in reliance
  upon and in conformity with information furnished to Realty or Operating by
  MT expressly for use in connection with such registration; and provided,
  further, that the indemnity agreement contained in this Section 6 shall not
  apply to the extent that any such loss is based on or arises out of an
  untrue statement or alleged untrue statement of a material fact, or an
  omission or alleged omission to state a material fact, contained in or
  omitted from any preliminary prospectus if the final prospectus shall
  correct such untrue statement or alleged untrue statement, or such omission
  or alleged omission, and a copy of the final prospectus has not been sent
  or given to such person at or prior to the confirmation of sale to such
  person if an underwriter was under an obligation to deliver such final
  prospectus and failed to do so.
 
  6.2. To the extent permitted by applicable law, MT shall indemnify and hold
harmless Realty, Operating, each of the directors, officers and employees of
Realty and Operating, and each Person, if any, who controls Realty or
Operating within the meaning of the Securities Act, against any and all
losses, claims, damages, liabilities and expenses (joint and several),
including reasonable attorneys' fees and disbursements and reasonable expenses
of investigation, incurred by such party pursuant to any actual or threatened
action, suit, proceeding or investigation, or to which any of the foregoing
Persons may otherwise become subject under the Securities Act, the Exchange
Act or other federal or state laws, but only insofar as such losses, claims,
damages, liabilities and expenses arise out of or are based upon any
Violation, in each case to the extent that such Violation arises out of or is
based upon information furnished by MT expressly for use in connection with
such registration; provided, however, that (x) the indemnification required by
this Section 6.2 shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or expense if such settlement is effected
without the consent of MT (which consent shall not be unreasonably withheld)
and (y) in no event shall the amount of any indemnity under this Section 6.2
exceed the gross proceeds from the applicable offering received by MT.
 
  6.3. Promptly after receipt by an indemnified party under this Section 6 of
notice of the commencement of any action, suit, proceeding, investigation or
threat thereof made in writing for which such indemnified party may make a
claim under this Section 6, such indemnified party shall deliver to the
indemnifying party a written notice thereof and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to
assume the defense thereof with counsel mutually satisfactory to the parties.
The failure to deliver written notice to the indemnifying party within a
reasonable time following the commencement of any such action, if prejudicial
to its ability to defend such action, shall relieve such indemnifying party of
any liability to the indemnified party under this Section 6 to the extent of
such prejudice but shall not relieve the indemnifying party of any liability
that it may have to any indemnified party otherwise than pursuant to this
Section 6. Any fees and expenses incurred by the indemnified party (including
any fees and expenses incurred in connection with investigating or preparing
to defend such action or proceeding) shall be paid to the indemnified party,
as incurred, within thirty (30) days of written notice thereof to the
indemnifying party. Any such indemnified party shall have the right to employ
separate counsel in any such action, claim or proceeding and to participate in
the defense thereof, but the fees and expenses of such counsel shall be the
expenses of such indemnified party unless (i) the indemnifying party has
agreed to pay such fees and expenses or (ii) the indemnifying party shall have
failed to promptly assume the defense of such action, claim or proceeding or
(iii) the named parties to any such action, claim or proceeding (including any
impleaded parties) include both such indemnified party and the
 
                                     A-52
<PAGE>
 
indemnifying party, and such indemnified party shall have been advised by
counsel that there may be one or more legal defenses available to it which are
different from or in addition to those available to the indemnifying party and
that the assertion of such defenses would create a conflict of interest such
that counsel employed by the indemnifying party could not faithfully represent
the indemnified party (in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such action, claim or proceeding on behalf of
such indemnified party, it being understood, however, that the indemnifying
party shall not, in connection with any one such action, claim or proceeding
or separate but substantially similar or related actions, claims or
proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses
of more than one separate firm of attorneys (together with appropriate local
counsel) at any time for all such indemnified parties, unless in the
reasonable judgment of such indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such action, claim or proceeding, in which event the indemnifying
party shall be obligated to pay the fees and expenses of such additional
counsel or counsels).
 
  6.4. If the indemnification required by this Section 6 from the indemnifying
party is unavailable to an indemnified party hereunder in respect of any
losses, claims, damages, liabilities or expenses referred to in this Section
6:
 
    (i) The indemnifying party, in lieu of indemnifying such indemnified
  party, shall contribute to the amount paid or payable by such indemnified
  party as a result of such losses, claims, damages, liabilities or expenses
  in such proportion as is appropriate to reflect the relative fault of the
  indemnifying party and indemnified parties in connection with the actions
  which resulted in such losses, claims, damages, liabilities or expenses, as
  well as any other relevant equitable considerations. The relative fault of
  such indemnifying party and indemnified parties shall be determined by
  reference to, among other things, whether any Violation has been committed
  by, or relates to information supplied by, such indemnifying party or
  indemnified parties, and the parties' relative intent, knowledge, access to
  information and opportunity to correct or prevent such Violation. The
  amount paid or payable by a party as a result of the losses, claims,
  damages, liabilities and expenses referred to above shall be deemed to
  include, subject to the limitations set forth in Section 6.1 and Section
  6.2, any legal or other fees or expenses reasonably incurred by such party
  in connection with any investigation or proceeding.
 
    (ii) The parties agree that it would not be just and equitable if
  contribution pursuant to this Section 6.4 were determined by pro rata
  allocation or by any other method of allocation which does not take into
  account the equitable considerations referred to in Section 6.4(i). No
  Person guilty of fraudulent misrepresentation (within the meaning of
  Section 11(f) of the Securities Act) shall be entitled to contribution from
  any Person who was not guilty of such fraudulent misrepresentation.
 
  6.5. If indemnification is available under this Section 6, the indemnifying
parties shall indemnify each indemnified party to the full extent provided in
this Section 6 without regard to the relative fault of such indemnifying party
or indemnified party or any other equitable consideration referred to in
Section 6.4.
 
  6.6. The obligations of Realty, Operating and MT under this Section 6 shall
survive the completion of any offering of Registrable Securities pursuant to a
registration statement under this Agreement, and otherwise.
