                                    PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference.

     The following documents of  MGM Grand heretofore filed with the Securities
and Exchange Commission are hereby incorporated by reference into the
Registration Statement:

     (a)  MGM Grand's Annual Report on Form 10-K for the fiscal year ended
December 31, 1997;
 
     (b)  All other reports filed pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934, as amended, since the end of the fiscal year
covered by MGM Grand's latest annual report or prospectus referred to in (a)
above.

     (c)  MGM Grand's definitive proxy statement, dated May 5, 1998, filed
pursuant to Section 14 of the Exchange Act.

     (d)  MGM Grand's information statement, dated February 5, 1999, filed
pursuant to Section 14 of the Exchange Act.

     (e)  The description of MGM Grand's Common Stock which is contained in MGM
Grand's registration statement filed under Section 12 of the Securities Exchange
Act of 1934, including any and all amendments or reports filed for the purpose
of updating such description.

     All reports and other documents subsequently filed by MGM Grand pursuant to
Sections 13(a) and (c), 14 and 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 in this Registration Statement and to
be a part hereof from the date of filing of such documents.

                                      -2-

 
Item 4.  Description of Securities.

     Not Applicable.

Item 5.  Interests of Named Experts and Counsel.

     Terry N. Christensen, a director of  MGM Grand and a partner of
Christensen, Miller, Fink, Jacobs, Glaser, Weil & Shapiro, LLP, which is
rendering an opinion in connection herewith as to the validity of MGM Grand
common stock, together with all other attorneys in such firm participating in
the preparation of this Registration Statement, beneficially own 8,820 shares of
MGM Grand's common stock.

Item 6.  Indemnification of Directors and Officers.

     Section 145 of the General Corporation Law of the State of Delaware
provides that a Delaware corporation may indemnify any persons, including
directors and officers, who are, or are threatened to be made, parties to any
threatened, pending or completed legal action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of such corporation), if, in connection with the matters in issue,
they acted in good faith and in a manner they reasonably believed to be in, or
not opposed to, the best interest of the corporation, and in connection with any
criminal suit or proceeding, if in connection with the matters at issue, they
had no reasonable cause to believe their conduct was unlawful.  Section 145 also
permits a Delaware corporation to indemnify its officers and directors in an
action by or in the right of the corporation under the same conditions against
expenses incurred by such persons in connection with the defense or settlement
of such action, except no such indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful and the merits are otherwise in the
defense of any action referred to above, the corporation must indemnify him or
her against the expenses which such officer or director actually and reasonably
incurred.

     Article II, Section 12 of the Bylaws of MGM Grand, Inc. provides for
indemnification of persons to the extent permitted by the Delaware General
Corporation Law.

     In accordance with Section 102(b)(7) of the Delaware Law, the Certificate
of Incorporation, as amended, of MGM Grand, Inc. limits the personal liability
of its directors for violations of their fiduciary duty.  The Certificate of
Incorporation eliminates each director's liability to MGM Grand, Inc. or its
stockholders for monetary damages except (i) for any breach of the director's
duty of loyalty to MGM Grand, Inc. or its stockholders, (ii)  for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii)  under the section of the Delaware law providing for
liability of directors for unlawful payment of dividends or unlawful stock
purchases or redemptions, or (iv) for any transaction from which a director
derived an improper personal benefit.  The effect of this provision is to
eliminate 

                                      -3-

 
the personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any such actions involving
gross negligence. This provision will not, however, limit in any way the
liability of directors for violations of the Federal securities laws.

Item 7.  Exemption From Registration Claimed.

     Not Applicable.

Item 8.  Exhibits.

4.1    MGM Grand, Inc. Replacement Stock Option Plan. (Incorporated by reference

4.2    MGM Grand, Inc. Directors' Replacement Stock Option Plan. (Incorporated

5      Opinion of Christensen, Miller, Fink, Jacobs, Glaser, Weil & Shapiro,
       LLP.

23.1   Consent of Christensen, Miller, Fink, Jacobs, Glaser, Weil & Shapiro, LLP
       (set forth as part of Exhibit 5).

23.2   Consent of Arthur Andersen LLP.

Item 9.  Undertakings.


     (a)  MGM Grand hereby undertakes:

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

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

          (ii)   to reflect in the prospectus any facts or events arising after
                 the effective date of the Registration Statement (or the most
                 recent post-effective amendment thereof) which, individually or
                 in the aggregate, represent a fundamental change in the
                 information set forth in the Registration Statement;

          (iii)  to include any material information with respect to the plan of
                 distribution not previously disclosed in the Registration
                 Statement or any material change to such information in the
                 Registration Statement;

                                      -4-

 
Provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and
(a)(1)(ii) of this section  do not apply if the information required to be
included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by MGM Grand pursuant
to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

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

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

(b) MGM Grand hereby undertakes that, for purposes of determining any liability
under the Securities Act of 1933, each filing of MGM Grand's annual report on
Form 10-K pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of
1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

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

                                      -5-

Statement to be signed on its behalf by the undersigned, thereunto duly
