Item 3.           Incorporation of Certain Documents By Reference

         On November 5, 1997, Meditrust, a Massachusetts business trust
("Meditrust") merged with and into Santa Anita Realty Enterprises, Inc.
("Realty"), with Realty as the surviving corporation, and Meditrust Acquisition
Company, a Massachusetts business trust ("MAC") merged with and into Santa Anita
Operating Company ("Operating," and together with Realty, "The Santa Anita
Companies"), with Operating as the surviving corporation. As part of the merger,
Realty changed its name to "Meditrust Corporation" and Operating changed its
name to "Meditrust Operating Company." Meditrust Corporation ("MC") and
Meditrust Operating Company ("MOC", and MC and MOC being sometimes referred to
herein individually as a "Registrant" and collectively as the "Registrants"),
are hereby registering additional securities of the same class as other
securities for which a registration statement filed on this form relating to the
same employee benefit plans is effective, and the contents of that earlier
registration statement, filed by The Santa Anita Companies with the Securities
and Exchange Commission on May 1, 1995 (File No. 033-58995), are incorporated
herein by reference, and any information required in this Registration Statement
that is not in the earlier registration statement is set forth in this
Registration Statement. The following documents of the Registrants and of
Meditrust, filed with the Securities and Exchange Commission, are incorporated
by reference herein:

     (a)  The Santa Anita Companies' Joint Annual Report on Form 10-K, as
          amended by amendments on Form 10K/A, for the fiscal year ended
          December 31, 1996;

     (g)  Meditrust's Quarterly Report on Form 10-Q for the quarter ended 
          June 30, 1997;

     (h)  Meditrust's Current Reports on Form 8-K, event date January 31, 1997,
          event date April 13, 1997 and event date July 30, 1997.

     (i)  The Registrants' Joint Current Report on Form 8-K, event date 
          November 5, 1997; and

     (j)  The descriptions of the MC Common Stock, the Rights, and the MOC
          Common Stock which are contained in registration statements filed
          under the Exchange Act, and any amendment or report filed for the
          purpose of updating such descriptions.

All documents subsequently filed by the Registrants and Meditrust pursuant to
Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act prior to the filing of a
post-effective amendment which indicates that all securities offered hereby have
been sold or which deregisters all securities then remaining unsold shall be
deemed to be incorporated by reference into this Joint Registration Statement
and to be a part hereof from the date of filing of such documents. Any statement
contained herein or in a document, all or a portion of which is incorporated or
deemed to be incorporated by reference herein, shall be deemed to be modified or
superseded for purposes of this Joint Registration Statement to the extent that
a statement contained herein or in any other subsequently filed document which
also is or is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or amended, to constitute a part of this
Joint Registration Statement.

Item 4. Interests of Named Experts and Counsel

     Michael J. Bohnen, a partner in the law firm Nutter, McClennen & Fish, LLP,
currently serves as Secretary of MOC. Nutter, McClennen & Fish, LLP, serves as
counsel to the Registrants, and has rendered a legal opinion with respect to the
validity of the shares being offered pursuant to this Registration Statement.

Item 5. Indemnification of Directors and Officers

     As permitted by Section 102 of the General Corporation Law of Delaware (the
"GCL"), both the Certificate of Incorporation of MC and the Certificate of
Incorporation of MOC eliminate personal liability of its respective directors to
such company or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for: (i) any breach of the duty of loyalty to such
company or its stockholders; (ii) acts or omissions not in good faith or which
involve intentional misconduct or knowing violations of law; (iii) liability
under Section 174 of the GCL relating to certain unlawful dividends and stock


                                      -4-




repurchases; or (iv) any transaction from which the director derived an improper
personal benefit.

     As permitted by Section 145 of the GCL, both MC's By-laws and MOC's By-laws
provide for indemnification of directors and officers (and permit the respective
Boards of Directors to provide for indemnification of employees and agents) of
such Registrants against all costs, charges, expenses, liabilities and losses
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and other amounts paid in settlement) actually and reasonably incurred by them
in connection with any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, in which
any such person was or is a party or is threatened to be made a party, if such
person acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best interest of such Registrant and, with respect to
any criminal action or proceeding, if such person had no reasonable cause to
believe his conduct was unlawful. In the case of an action or suit by or in the
right of the respective Registrant, such a person may be indemnified only for
expenses (including attorneys fees) and may not be indemnified in respect of any
claim, issue or matter as to which he has been adjudged liable for negligence or
misconduct in the performance of his duty to the respective Registrant, unless
and only to the extent the court in which such action or suit was brought
determines that such person is fairly and reasonably entitled to indemnity for
such expenses as such court may deem proper. In each case, indemnification of an
officer or director shall be made only upon specific authorization of a majority
of disinterested directors, by written opinion of independent legal counsel or
by the stockholders, unless the officer, or director has been successful on the
merits or otherwise in defense of any such action or suit, in which case he
shall be indemnified without such authorization. Both MC's By-laws and MOC's
By-laws require such Registrant to pay the expenses incurred by a director or
officer in defending or investigating a threatened or pending action, suit or
proceeding in advance of the final disposition of such action, suit or
proceeding upon receipt by such Registrant of an undertaking by or on behalf of
such director or officer to repay such amount if it is ultimately determined
that he is not entitled to indemnification and permit such Registrant to advance
such expenses to other employees and agents of such Registrant upon such terms
and conditions as are specified by the respective Registrant's Board of
Directors. The advancement of expenses, as well as indemnification, pursuant to
each Registrant's Bylaws is not exclusive of any other rights which those
seeking indemnification or advancement of expenses from such Registrant may
have.

     Individual indemnification agreements (the "Indemnification Agreements")
have been entered into by each of MC and MOC with certain of its respective
directors and officers. The Indemnification Agreements provide for
indemnification to the fullest extent permitted by law and provide contractual
assurance to directors and officers that indemnity and advancement of expenses
will be available to them regardless of any amendment or revocation of such
Registrant's Bylaws.



                                      -5-




     Both MC's By-laws and MOC's By-laws permit such Registrant to purchase and
maintain insurance on behalf of any director, officer, employee or agent of such
Registrant against liability asserted against him or her in any such capacity,
whether or not such Registrant would have the power to indemnify him against
such liability under the provisions of the Bylaws. Both MC and MOC maintain
liability insurance providing officers and directors with coverage with respect
to certain liabilities.
