                                  ARTICLE III.

                  The nature of the business or purposes to be conducted or
promoted by the Corporation is to engage in any lawful act or activity for which
corporations may be organized under the General Corporation Law of the State of
Delaware.

                                  ARTICLE IV.

         Section 4.1. Authorized Shares. The total number of shares of stock
which the Corporation shall have authority to issue is (a) 1,100,000 shares of
Common Stock, consisting of 600,000 shares of Class A Common Stock, par value
$.01 per share (the "Class A Common Stock"), and 500,000 shares of Class B
Common Stock, par value $.01 per share (the "Class B Common Stock") and,
together with the Class A Common Stock, the "Common Stock"), and (b) 50,000
shares of Preferred Stock, par value $.01 per share (the "Preferred Stock").

         Section 4.2. Preferred Stock. The Board of Directors is expressly
authorized to provide for the issuance of all or any shares of the Preferred
Stock in one or more classes or series, and to fix for each such class or series
such voting powers, full or limited, or no voting powers, and such distinctive
designations, preferences and relative, participating, optional or other special
rights and such qualifications, limitations or restrictions thereof, as shall be
stated and expressed in the resolution or resolutions adopted by the Board of
Directors providing for the issuance of such class or series including, without
limitation, the authority to provide that any such class or series may be (i)
subject to redemption at such time or times and at such price or prices; (ii)
entitled to receive dividends (which may be cumulative or non-cumulative) at
such rates, on such conditions, and at such times, and payable in preference to,
or in such relation to, the dividends payable on any other class or classes or
any other series; (iii) entitled to such rights upon the dissolution of, or upon
any distribution of the assets of, the Corporation; or (iv) convertible into, or
exchangeable for, shares of any other class or classes of stock, or of any other
series of the same or any other class or classes of stock, of the Corporation at
such price or prices or at such rates of exchange and with such adjustments, all
as may be stated in such resolution or resolutions. Notwithstanding the
foregoing, the rights of each holder of Preferred Stock shall be subject at all
times to compliance with all gaming and other statutes, laws, rules and
regulations applicable to the Corporation and such holder at that time.

         Section 4.3. Class A Common Stock and Class B Common Stock.

         (a) Ranking. Except as provided in this Section 4.3, the Class A Common
Stock and the Class B Common Stock shall have the same rights and privileges and
shall rank equally, share ratably and be identical in all respects as to all
matters, including rights in liquidation.

         (b) Dividends. Subject to the rights of holders of Preferred Stock,
when, as and if dividends are declared on the Common Stock, whether payable in
cash, in property or in securities of the Corporation, the holders of Class A
Common Stock and Class B Common Stock shall be entitled to share equally, share
for share, in such dividends; provided that if dividends or distributions are
declared that are payable in shares of, or in subscription or other rights to
acquire shares of, Class A Common Stock or Class B Common Stock, dividends or
distributions



                                      -2-



payable in shares of, or in subscription or other rights to acquire shares of,
any particular class of Common Stock shall be payable only to holders of such
class of Common Stock.

         (c) Conversion. Each of Colony Investors IV, L.P., a Delaware limited
partnership, and its successor entities and affiliates (as such term is defined
in Rule 501(b) under the Securities Act of 1933, as amended) (collectively, the
"Designated Class B Holders") shall have the right at any time, at their option,
to convert any of their shares of Class B Common Stock into an equal number of
shares of Class A Common Stock, without cost. So long as the Designated Class B
Holders in the aggregate hold at least one share of Class B Common Stock, no
holder of Class B Common Stock who is not a Designated Class B Holder may
convert such stock into Class A Common Stock without the prior written consent
of Designated Class B Holders holding a majority of the outstanding Class B
Common Stock then held by Designated Class B Holders (which consent may be
granted in each such holder's sole and absolute discretion). At any time that no
Designated Class B Holder holds any Class B Common Stock, each holder of Class B
Common Stock who is not a Designated Class B Holder shall have the right, at its
option, to convert any of its share of Class B Common Stock into an equal number
of shares of Class A Common Stock, without cost. Notwithstanding the foregoing,
the rights of each holder of Class B Common Stock to convert such stock into
Class A Common Stock shall be subject at all times to compliance with all gaming
and other statutes, laws, rules and regulations applicable to the Corporation
and such holder at that time. So long as the Corporation shall continue to be an
entity qualifier with the New Jersey Casino Control Commission, the Designated
Class B Holders shall only be permitted to convert shares of Class B Common
Stock into shares of Class A Common Stock as part of or following an in kind
distribution of the entire interest of Colony Investors IV, L.P. in the shares
of the Corporation and, to the extent required, only after being found qualified
by the New Jersey Casino Control Commission. Upon any distribution of shares of
Class B Common Stock to the limited partners of Colony Investors IV, L.P., such
limited partners shall obtain qualification or waiver to the extent required by
the New Jersey Casino Control Act, N.J.S.A. 5:12-1 et seq.

         (d) Subdivisions and Combinations of Shares. If the Corporation in any
manner subdivides or combines the outstanding shares of one class of Common
Stock, the outstanding shares of the other class of Common Stock will be
likewise subdivided or combined.

         (e) Liquidation or Dissolution. In the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, holders
of Class A Common Stock and holders of Class B Common Stock shall receive a pro
rata distribution of any remaining assets after payment or provision for
liabilities and the liquidation preference on Preferred Stock, if any.

         (f) Reservation of Class A Common Stock for Conversion. The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Class A Common Stock or its treasury shares, solely for the purpose of
issuance upon the conversion of the Class B Common Stock, such number of shares
of Class A Common Stock as may be issued upon conversion of all outstanding
Class B Common Stock.

         (g) Voting Rights. The holders of Class A Common Stock shall be
entitled to one vote per share on all matters to be voted on by the stockholders
of the Corporation, and except as otherwise required by the General Corporation
Law of the State of Delaware, the holders of the



                                      -3-



Class B Common Stock shall have no right to vote on any matter to be voted on by
the stockholders of the Corporation (including, without limitation, any election
or removal of the directors of the Corporation) and the Class B Common Stock
shall not be included in determining the number of shares voting or entitled to
vote on such matters.

         (h) Consideration for Shares. The Common Stock and Preferred Stock
authorized by this Article shall be issued for such consideration as shall be
fixed, from time to time, by the Board of Directors.

         (i) Assessment of Stock. The capital stock of the Corporation, after
the amount of the subscription price has been fully paid in, shall not be
assessable for any purpose, and no stock issued as fully paid shall ever be
assessable or assessed. No stockholder of the Corporation is individually liable
for the debts or liabilities of the Corporation.

         (j) Cumulative Voting For Directors. No stockholder of the Corporation
shall be entitled to cumulative voting of his shares for the election of
directors.

         (k) Preemptive Rights. No stockholder of the Corporation shall have any
preemptive rights.

                                   ARTICLE V.

         Section 5.1. Issuance of Securities in accordance with Gaming Laws. The
Corporation shall not issue any stock or securities except in accordance with
the provisions of the New Jersey Casino Control Act (the "NJCCA") and the
regulations promulgated thereunder. The issuance of any stock or securities in
violation thereof shall be ineffective and such stock or securities shall be
deemed not to be issued and outstanding until (a) the Corporation shall cease to
be subject to the jurisdiction of the New Jersey Casino Control Commission (the
"Commission"), or (b) the Commission shall, by affirmative action, validate said
issuance or waive any defect in issuance.

         Section 5.2. Transfer of Securities in accordance with the NJCCA. No
stock or securities issued by the Corporation and no interest, claim or charge
therein or thereto shall be transferred in any manner whatsoever, except in
accordance with the provisions of the NJCCA and the regulations promulgated
thereunder. The Corporation has the absolute right to repurchase at the lesser
of the market price and the purchase price, any security, share or other
interest in the Corporation in the event the Commission disapproves a transfer
in accordance with the provisions of the NJCCA or the Commission determines that
the holder of any security, share or other interest in the Corporation is
unsuitable to hold such security, share or other interest in the Corporation.
Any transfer in violation thereof shall be ineffective until (a) the Corporation
shall cease to be subject to the jurisdiction of the Commission, or (b) the
Commission shall validate said transfer or waive any defect in said transfer.

         Section 5.3. Unsuitability to Hold Securities. If the Commission at any
time determines that a holder of stock or other securities of this Corporation
is unsuitable to hold such securities, then until such securities are held by
persons found by the Commission to be suitable to hold them, (a) the Corporation
shall not be required or permitted to pay any dividend or interest with regard
to the securities, (b) the holder of such securities shall not be entitled to
vote on any matter as the holder of the securities, or to exercise, directly or
indirectly or through any proxy,



                                      -4-



trustee or nominee, any voting or other right conferred by such securities, and
such securities shall not for any purposes be included in the securities of the
Corporation entitled to vote, and (c) neither the Corporation nor any affiliate
of the Corporation shall pay any remuneration in any form to the holder of the
securities.

                                  ARTICLE VI.

                  Meetings of stockholders may be held within or without the
State of Nevada, as the By-Laws may provide. The books of the Corporation may be
kept (subject to any provision contained in the Nevada Private Corporation Law)
outside the State of Nevada at such place or places as may be designated from
time to time by the Board of Directors or in the By-Laws of the Corporation.

                                  ARTICLE VII.

                  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in these Articles of Incorporation, in the manner
now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

                                 ARTICLE VIII.

                  The name and mailing address of the Incorporator is as
follows:

                              Adam Turteltaub, Esq.
                            Willkie Farr & Gallagher
                               787 Seventh Avenue
                          New York, New York 10019-6099

                                  ARTICLE IX.

                  In furtherance and not in limitation of the powers conferred
by statute, the by-laws of the Corporation may be made, altered, amended or
repealed by the stockholders or by a majority of the entire board of directors
of the Corporation (the "Board").

                                   ARTICLE X.

                  Elections of directors need not be by written ballot.

                                  ARTICLE XI.

         (a) The Corporation shall indemnify to the fullest extent permitted
under and in accordance with the laws of the State of Delaware any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Corporation) by
reason of the fact that the person is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in



                                      -5-



settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding if the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which the person reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that the person's
conduct was unlawful.

         (b) The Corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the Corporation to procure a judgment in its favor
by reason of the fact that the person is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against expenses (including attorneys'
fees) actually and reasonably incurred by the person in connection with the
defense or settlement of such action or suit if the person acted in good faith
and in a manner the person reasonably believed to be in or not opposed to the
best interests of the Corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
or such other court shall deem proper.

         (c) Expenses incurred in defending a civil or criminal action, suit or
proceeding shall (in the case of any action, suit or proceeding against a
director of the Corporation) or may (in the case of any action, suit or
proceeding against an officer, trustee, employee or agent) be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board upon receipt of an undertaking by or on
behalf of the indemnified person to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the Corporation as
authorized in this Article XI.

         (d) The indemnification and other rights set forth in this Article XI
shall not be exclusive of any provisions with respect thereto in the by-laws of
the Corporation or any other contract or agreement between the Corporation and
any officer, director, employee or agent of the Corporation.

         (e) Neither the amendment nor repeal of this Article XI, nor the
adoption of any provision of this Certificate of Incorporation inconsistent with
Article XI, shall eliminate or reduce the effect of this Article XI in respect
of any matter occurring before such amendment, repeal or adoption of an
inconsistent provision or in respect of any cause of action, suit or claim
relating to any such matter which would have given rise to a right of
indemnification or right to receive expenses pursuant to this Article XI if such
provision had not been so amended or repealed or if a provision inconsistent
therewith had not been so adopted.



                                      -6-



         (f) No director shall be personally liable to the Corporation or any
stockholder for monetary damages for breach of fiduciary duty as a director;
provided, however, that the foregoing shall not eliminate or limit the liability
of a director:

                  (i)      for any breach of the director's duty of loyalty to
                           the Corporation 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 Section 174 of the General Corporation Law of
                           the State of Delaware; or

                  (iv)     for any transaction from which the director derived
                           an improper personal benefit.

                  If the General Corporation Law of the State of Delaware is
amended after April 2, 2001 to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of a director
of the Corporation shall be eliminated or limited to the fullest extent
permitted by the General Corporation Law of the State of Delaware, as so
amended.




                                      -7-
