                      ALAN J. RIVIN STOCK OPTION AGREEMENT


         THIS STOCK OPTION AGREEMENT (this "Agreement"), dated as of the first
day of October, 2001 (the "Effective Date"), by and between COLONY RIH HOLDINGS,
INC., a Delaware corporation (the "Company"), and ALAN J. RIVIN (the "Optionee")
in his capacity as the Senior Vice President - Hotel Operations of the Resorts
International Hotel, Inc., a New Jersey corporation and a Subsidiary of the
Company ("Resorts").

         Pursuant to the Colony RIH Holdings, Inc. 2001 Omnibus Stock Incentive
Plan (the "Plan"), the Board of Directors of the Company (the "Board"), as the
Administrator of the Plan, has determined that the Optionee is to be granted an
option (the "Option") to purchase shares of the Company's Class A Common Stock,
par value $.01 per share (the "Class A Common Stock"), and shares of the
Company's 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"), each on
the terms and conditions set forth herein, and hereby grants such Option. Such
grants shall be deemed to satisfy in full the obligations under Paragraph 4(b)
of that certain Employment Agreement between the Optionee and Resorts, as
hereinafter amended (the "Employment Agreement"). Such grants shall also be
conditioned on the Optionee agreeing to be bound by the Stockholders Agreement
(as defined below) with respect to the Common Stock, and shall evidence such
agreement by executing a joinder agreement substantially in the form of Exhibit
A attached hereto.

         All capitalized terms not defined herein shall have their respective
meanings set forth in the Plan.

         1. Terms of Option Grant. (a) The Option entitles the Optionee to
purchase 77 shares of the Company's Class A Common Stock at a price equal to
$0.0475 per share (the "Class A Option Exercise Price"), which the parties
acknowledge is not less than the fair market value of one share of the Class A
Common Stock as of the Effective Date. The Option also entitles the Optionee to
purchase 1,556 shares of the Company's Class B Common Stock at a price equal to
$100.00 per share (the "Class B Option Exercise Price" and, collectively with
the Class A Option Exercise Price, the "Option Exercise Price"), which the
parties acknowledge is not less than the fair market value of one share of the
Class B Common Stock as of the Effective Date. The shares of Class A Common
Stock and Class B Common Stock subject to the Option are referred to herein as
the "Option Shares." It is intended that the Option shall not constitute an
"incentive stock option" within the meaning of Section 422 of the Code.

                  (b) The term of the Option (the "Option Term") shall commence
on the Effective Date (the "Date of Grant") and, unless the Option is previously
terminated pursuant to this Agreement, shall terminate upon the expiration of
ten (10) years from the Date of Grant.

<PAGE>

Upon expiration of the Option Term, all rights of the Optionee hereunder shall
terminate.

                  (c) Except as otherwise provided in Section 5 hereof, the
Option shall vest and become exercisable if the conditions set forth below are
satisfied as of the end of the applicable vesting period:

                  (i) For the Company's fiscal year ended December 31, 2001, 20%
         of the Option Shares shall vest and become exercisable provided the
         Company achieves the applicable operating performance targets as
         established by the Board for such fiscal year.

                  (ii) For the Company's fiscal year ended December 31, 2002,
         20% of the Option Shares shall vest and become exercisable provided the
         Company achieves the applicable operating performance targets as
         established by the Board for such fiscal year.

                  (iii) For the Company's fiscal year ended December 31, 2003,
         20% of the Option Shares shall vest and become exercisable provided the
         Company achieves the applicable operating performance targets as
         established by the Board for such fiscal year.

                  (iv) For the Company's fiscal year ended December 31, 2004,
         20% of the Option Shares shall vest and become exercisable provided the
         Company achieves the applicable operating performance targets as
         established by the Board for such fiscal year.

                  (v) For the Company's fiscal year ended December 31, 2005, 20%
         of the Option Shares shall vest and become exercisable provided the
         Company achieves the applicable operating performance targets as
         established by the Board for such fiscal year.

                  (vi) Notwithstanding the foregoing clauses (i) through (v) of
         this Section 1(c), in the event that the Company fails to meet the
         applicable performance target described above for any fiscal year (a
         "Shortfall Year"), but it achieves more than 100% of the applicable
         performance target for the fiscal year immediately following the
         Shortfall Year and the excess is at least the amount of the shortfall
         in the Shortfall Year (that is, the difference between the Shortfall
         Year's performance target and the performance actually generated by the
         Company in such Shortfall Year), then the Option Shares that would have
         vested in the Shortfall Year if the performance target had been
         satisfied shall vest retroactively as if the performance target in the
         Shortfall Year had been satisfied. Until such time as the Option Shares
         described herein are retroactively vested, they shall be considered as
         forfeited for all purposes of the Plan and this Agreement.

                  (d) Except as otherwise provided herein, the right of the
Optionee to purchase Option Shares with respect to which the Option has become
exercisable may be exercised in whole or in part at any time or from time to
time prior to expiration of the Option Term, provided, that any exercise of the
Option shall be deemed to relate in tandem to both the Class A Common Stock and
the Class B Common Stock subject to the Option, such that the ratio of (i) the
number of shares of Class A Common Stock issuable upon such exercise to (ii) the
total number of shares of Class A Common Stock outstanding on the date hereof
shall be the same as the ratio of (iii) the number of shares of Class B Common
Stock issuable upon such exercise to (iv) the total number of shares of Class B
Common Stock outstanding on the date hereof.

                  (e) The Option may be exercised by means of written notice of
exercise to the Company specifying the number of Option Shares to be purchased,
accompanied by payment in full of the aggregate Option Exercise Price and any
applicable withholding amounts (i) in cash or by check, (ii) at any time
following the closing of the Company's Initial Public Offering (as defined in
Section 2 below) by means of a broker cashless exercise procedure, on terms
reasonably acceptable to the Company, providing proceeds sufficient to pay the
exercise price and any applicable withholding amounts or (iii) by any other
means of exercise authorized from time to time in the Plan and/or by the Board.

         2. Certain Definitions. For purposes of this Agreement:

                  (a) "Initial Public Offering" shall mean the closing of a

permitted to transfer the Option and this Agreement to a trust controlled by the
Optionee during the Optionee's lifetime for estate planning purposes. Without


                                       4
<PAGE>

limiting the generality of the foregoing, except as otherwise provided herein,
the Option may not be assigned, transferred, pledged or hypothecated in any way,
shall not be assignable by operation of law, and shall not be subject to
execution, attachment or similar process. Any attempted assignment, transfer,
pledge, hypothecation or other disposition of the Option contrary to the
provisions hereof, and the levy of any execution, attachment or similar process
upon the Option shall be null and void and without effect.

                  (b) Notwithstanding any provision herein to the contrary, the

and in all respects be subject to the Stockholders Agreement, the provisions of
which shall be deemed to be incorporated into this Agreement.

         5. Forfeiture and Vesting Acceleration of Options. (a) If the
Optionee's services with Resorts are terminated by Resorts without Cause (as
defined in the Employment Agreement), the Option shall immediately vest and
become exercisable as to that number of Option Shares that would have vested
pursuant to Section 1(c) had the Optionee's services continued without
interruption under the Employment Agreement until December 31 following such
termination date notwithstanding any performance targets established with
respect to the Option Shares. Anything herein to the contrary notwithstanding,
the termination of the Optionee's services without Cause shall not result in the
vesting of any Option Shares that were forfeited at any time prior to such
termination date by reason of the Company's failing to satisfy any performance
targets relating to such Option Shares. Following the Optionee's termination
date, the unexercised portion of the Option, to the extent vested, shall remain
exercisable for ninety (90) days after the Optionee's termination date, at which
time all Option Shares, to the extent not exercised prior to the end of such
period, shall lapse and be canceled.

                  (b) If the Optionee's services with Resorts shall terminate by
reason of his death or disability, the Option shall immediately vest and become
exercisable as to that number of Option Shares that would have vested pursuant
to Section 1(c) had the Optionee's services continued without interruption under
the Employment Agreement until December 31 following the Optionee's death or the
forty-fifth (45th) day after receipt of notice of termination for disability, as
applicable, notwithstanding any performance targets established with respect to
the Option Shares. Anything herein to the contrary notwithstanding, the
termination of the Optionee's services due to death or disability shall not
result in the vesting of any Option Shares that were forfeited at any time prior
to such termination by reason of the Company's failing to satisfy any
performance targets relating to such Option Shares. Following the Optionee's
termination date, the unexercised portion of the Option, to the extent vested,
shall remain exercisable for ninety (90) days after the Optionee's death or the
forty-fifth (45th) day after receipt of notice of termination for disability, as
applicable, at which time all Option Shares, to the extent not exercised prior
to the end of such period, shall lapse and be canceled.

                  (c) If the Optionee's services with Resorts are terminated by
the Optionee, the unexercised portion of the Option, to the extent vested, shall
remain exercisable for ninety (90) days after such termination, at which time
all Option Shares, to the extent not exercised prior to the end of such period,
shall lapse and be canceled.

                  (d) If the Optionee's services with Resorts are terminated by
Resorts


                                       5
<PAGE>

for Cause (as defined in the Employment Agreement), the unexercised portion of
the Option, whether exercisable or not, shall lapse and be immediately canceled
as of the date of such termination.

                  (e) Upon the occurrence of a Change in Control (as defined in
Section 2) at any time prior to the termination of the Optionee's services with
Resorts, for any or no reason, the Option shall immediately vest and become
exercisable as to 100% of the Option Shares (notwithstanding any performance
targets established with respect to such Option Shares) and all provisions of
this Agreement relating to the forfeiture of the Option in the event of the
Optionee's termination of service with Resorts shall expire. Anything herein to
the contrary notwithstanding, the occurrence of a Change in Control shall not
result in the vesting of any Option Shares that were forfeited at any time prior
to such Change in Control by reason of the Company's failing to satisfy any
performance targets relating to such Option Shares.

         6. Call Rights. In the event of (i) the termination of the Optionee's
employment with Resorts at any time, under any circumstances and for any or no
reason, (ii) a Change in Control or (iii) any transfer of any Option Shares by
the Optionee under any circumstances (other than to a trust controlled by the
Optionee for estate planning purposes, the trustee of which agrees in writing to
be subject in all events and for all purposes to the Company's Call as set forth
herein), including pursuant to any arrangement, proceeding, decree, judgment,
order or application of law relating to the division of property for domestic
relations purposes (each a "Call Event"), for a period commencing on the date of
such event and expiring upon the Company's Initial Public Offering (the "Call
Exercise Period"), the Company shall have the right to purchase from the
Optionee, in accordance with the terms hereof and of Section 2.4(e) of the
Stockholders Agreement (the "Call") (y) any or all of such portion of the Option
as shall relate to vested and exercisable Option Shares as of the date written
notice is given (the "Call Exercise Date"), and/or (z) any or all Option Shares
owned by the Optionee as of the end of business on the Call Exercise Date.

                  (a) The following terms and conditions shall apply to the
exercise of the Call:

                  (i) If exercising its rights under (y) above, the Company
         shall pay the Optionee an amount in cash equal to the product of (A)
         the excess, if any, of the Fair Market Value (as defined, for purposes
         of this Section 6, in the Stockholders Agreement with respect to
         Employee Stockholders other than the Qualified Stockholders) of a share
         of Class A Common Stock or Class B Common Stock, as applicable, as of
         the first applicable Call Event (the "Call Price") over the Class A
         Option Exercise Price or Class B Option Exercise Price, as applicable,
         and (B) the number of shares of Class A Common Stock or Class B Common
         Stock, as applicable, that the portion of the Option being purchased by
         the Company pursuant to the Call would otherwise entitle the Optionee
         to purchase.

                  (ii) If exercising its rights under (z) above, the Company
         shall pay the Optionee an amount equal to the product of (A) the Call
         Price and (B) the number of Option Shares being purchased pursuant
         thereto.

                                       6
<PAGE>

                  (b) The Company may elect to exercise the Call, at its
discretion, at any time prior to the end of the Call Exercise Period in
accordance with the procedures set forth in Section 2.4 of the Stockholders
Agreement with respect to "Offered Securities;" provided, however, that if the
Company does not exercise the Call within fifteen (15) days after the occurrence
of the first Call Event, the Call Price for the Option Shares being repurchased,
as determined above, shall be increased by 10% interest (6% interest if the Call
Event occurs in connection with the Optionee's termination of employment by the
Company for Cause (as defined in the Employment Agreement) or the Optionee's
resignation from employment with the Company), compounded annually on the basis
of the actual number of days elapsed over a year of 365 days, from the date of
such Call Event until the date of the Company's payment.

                  (c) Notwithstanding any other provision hereof, the Company
may assign, without the consent of the Optionee, its rights under this Section
6.

                  (d) Unless the Company shall have given prior notice of its
intent to exercise the Call, the Call shall terminate upon the closing of the
Company's Initial Public Offering.

         7. Investment Representation. The Optionee hereby represents and
warrants to the Company that the Optionee, by reason of the Optionee's business
or financial experience (or the business or financial experience of the
Optionee's professional advisors who are unaffiliated with and who are not
compensated by the Company or any affiliate or selling agent of the Company,
directly or indirectly), has the capacity to protect the Optionee's own
interests in connection with the transactions contemplated under this Agreement.

Either party hereto may change such party's address for notices by notice duly
given pursuant hereto.

         9. Securities Laws Requirements. The Option shall not be exercisable to
any extent, and the Company shall not be obligated to transfer any Option Shares
to the Optionee upon exercise of the Option, if such exercise, in the opinion of
counsel for the Company, would violate the Securities Act (or any other federal
or state statutes having similar requirements as may be in effect at that time).
Further, the Company may require as a condition of transfer of any Option Shares
pursuant to any exercise of the Option that the Optionee furnish a written
representation that he is purchasing or acquiring the Option Shares for
investment and not with a view to resale or distribution to the public. The
Optionee hereby represents and warrants that he understands that the Option
Shares are "restricted securities," as defined in Rule 144 under the Securities
Act, and that any resale of the Option Shares must be in compliance with the
registration requirements of the Securities Act or an exemption therefrom. Each
certificate representing Option Shares shall bear the legend set forth below:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED,
         SOLD, ASSIGNED, HYPOTHECATED OR OTHERWISE DISPOSED OF (A "TRANSFER")
         EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF THAT CERTAIN STOCK OPTION
         AGREEMENT, DATED AS OF OCTOBER 1, 2001, BETWEEN COLONY RIH HOLDINGS,
         INC., A DELAWARE CORPORATION (THE "COMPANY"), AND ONE OF ITS EXECUTIVES
         AND THAT CERTAIN STOCKHOLDERS AGREEMENT, DATED AS OF APRIL 25, 2001, BY
         AND AMONG THE COMPANY AND CERTAIN OF ITS STOCKHOLDERS. ANY TRANSFEREE
         OF THESE SECURITIES SHALL TAKE SUBJECT TO THE TERMS OF SUCH AGREEMENTS,
         COPIES OF WHICH ARE ON FILE WITH THE COMPANY.

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR ANY STATE SECURITIES
         LAWS, AND NO TRANSFER OF THESE SECURITIES MAY BE MADE EXCEPT (A)
         PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT, OR (B)
         PURSUANT TO AN EXEMPTION THEREFROM WITH RESPECT TO WHICH THE COMPANY
         MAY, UPON REQUEST, REQUIRE A SATISFACTORY OPINION OF COUNSEL FOR THE
         HOLDER THAT SUCH TRANSFER IS EXEMPT FROM THE REQUIREMENTS OF THE ACT.

Further, if the Company determines that the listing or qualification of the
Option Shares under any securities or other applicable law is necessary in order
to avoid a violation of any securities laws, the Option shall not be
exercisable, in whole or in part, unless and until such listing or
qualification, or a consent or approval with respect thereto, shall have been
effected or obtained free of any conditions not acceptable to the Company,
provided, that the Company shall pursue such listing or qualification diligently
and in good faith.

         10. No Obligation to Register Shares. Except as provided in the
Stockholders Agreement, the Company shall be under no obligation to register the
Option Shares.

                                       8
<PAGE>

         11. Protections Against Violations of Agreement. No purported sale,
assignment, mortgage, hypothecation, transfer, pledge, encumbrance, gift,
transfer in trust (voting or other) or other disposition of, or creation of a
security interest in or lien on, any of the Option Shares by any holder thereof
in violation of the provisions of this Agreement, the Stockholders Agreement,
the Employment Agreement or the Certificate of Incorporation or the Bylaws of
the Company, will be valid, and the Company will not transfer any of said Option
Shares on its books nor will any of the Option Shares be entitled to vote, nor
will any dividends be paid thereon, unless and until there has been full
compliance with such provisions to the satisfaction of the Company. The
foregoing restrictions are in addition to and not in lieu of any other remedies,
legal or equitable, available to enforce such provisions.

         12. Withholding Requirements. The Optionee shall, no later than the
date as of which the value of any award hereunder becomes includable in his
gross income (after taking into account the provisions of Section 3 hereof), pay
to the Company, or make arrangements satisfactory to the Company regarding
payment of, any federal, state, or local taxes or other amounts of any kind
required by law to be withheld with respect thereto. The obligations of the
Company hereunder shall be conditional on the making of such payments or
arrangements, and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

         13. Failure to Enforce Not a Waiver. The failure to enforce at any time
any provision of this Agreement shall in no way be construed to be a waiver of
such provision or of any other provision hereof.

         14. Governing Law. This Agreement shall be governed by and construed
according to the laws of the State of New York without regard to its principles
of conflict of laws.

         15. Incorporation of Plan. The Plan is hereby incorporated by reference
and made a part hereof, and the Option award and this Agreement shall be subject
to all terms and conditions of the Plan; provided, however, that in the event of
a conflict between the terms of this Agreement and the Plan, the terms of this
Agreement shall govern.

         16. Amendments. This Agreement may be amended or modified at any time
only by an instrument in writing signed by each of the parties hereto.

         17. Rights as a Stockholder. Neither the Optionee nor any of the
Optionee's successors in interest shall have any rights as a stockholder of the
Company with respect to any shares of Common Stock subject to the Option until
the date of issuance of a stock certificate for such shares of Common Stock.

         18. Agreement Not a Contract of Service. Neither the Plan, the granting
of the Option, this Agreement nor any other action taken pursuant to the Plan
shall constitute or be evidence of any agreement or understanding, express or
implied, that the Optionee has a right to continue in the service of the Company
or any Subsidiary or affiliate of the Company for any period of time or at any
specific rate of compensation.


                                       9

         19. Authority of the Administrator. The Administrator shall have full
authority to interpret and construe the terms of the Plan and this Agreement,
and shall do so in good faith.

         20. Dispute Resolution. Any dispute arising under this Agreement shall
be resolved in accordance with the arbitration provisions of the Stockholders
Agreement as in effect as of the date hereof, or as the same may be amended from
time to time, and such arbitration provisions shall be deemed to be incorporated
herein by this reference.

         21. Market Stand-Off. In connection with any underwritten public
offering by the Company of its equity securities pursuant to an effective
registration statement filed under the Securities Act for such period as the
Company or its underwriters may request (such period not to exceed 180 days
following the date of the applicable offering), the Optionee shall not, directly
or indirectly, sell, make any short sale of, loan, hypothecate, pledge, offer,
grant or sell any option or other contract for the purchase of, purchase any
option or other contract for the sale of, or otherwise dispose of or transfer,
or agree to engage in any of the foregoing transactions with respect to, any
Option Shares acquired under this Agreement without the prior written consent of
the Company or its underwriters, provided, that the Optionee shall not be
required to be subject to "lock-up" restrictions that are more restrictive than
such restrictions to which any other Employee Stockholder (as defined in the
Stockholders Agreement) is subject, or that would prevent the Optionee from
effectuating a sale pursuant to Section 2.5 of the Stockholders Agreement.

         IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first above written.

                                                COLONY RIH HOLDINGS, INC.
