amounts paid in the investigation, defense and/or settlement of any claim, 
action or proceeding (collectively, "EXPENSES"), that relate to (i) the

have no obligation to indemnify, defend and hold harmless any Hilton Party 
Indemnitee under clause (i) above from any Expenses resulting from any claim

thereof to the party or parties from whom indemnification is sought (the 
"INDEMNITOR") promptly, but in no event later than thirty (30) days after 
such Indemnified Party learns of the existence of such Proceeding; PROVIDED, 
HOWEVER, that the Indemnified Party's failure to give the Indemnitor prompt 
notice shall not bar the Indemnified Party's right to indemnification unless 
such failure has materially prejudiced the Indemnitor's ability to defend 
such Proceeding.  The Indemnitor shall have the right to employ counsel 
reasonably acceptable to the Indemnified Party to defend any such Proceeding, 
or to compromise, settle or otherwise dispose of the same, if the Indemnitor 
deems it advisable to do so, all at the expense of the Indemnitor, PROVIDED 
that the Indemnitor shall not have the right to control the defense of any 
such Proceeding unless it has acknowledged in writing its obligation to 
indemnify the Indemnified Party fully from all Expenses incurred as a result 
of such Proceeding.  The Indemnitor shall not settle, or consent to the entry 
of any judgment in, any Proceeding without obtaining either (i) an 
unconditional release of the Indemnified Party from all liability with 
respect to all claims underlying such Proceeding or (ii) the prior written 
consent of the Indemnified Party.  Each Indemnitor and each Indemnified Party 
will fully cooperate with each other in any such Proceeding and shall make 
available to each other any books or records useful for the defense of any 
such Proceeding.  If the Indemnitor fails to acknowledge in writing its 
obligation to defend against such Proceeding within fifteen (15) days after 
receiving written notice thereof as provided above, the Indemnified Party 
shall be free to dispose of the matter, at the expense of the Indemnitor, in 
any way in which the Indemnified Party reasonably deems to be in its best 
interest.

               (e)  The parties hereto are also subject to indemnification 
provisions in the Distribution Agreement.  The indemnification provisions set 
forth herein are intended to supplement, but not to replace, the 
indemnification provisions in the Distribution Agreement.  To the extent the 
indemnification provisions set forth herein conflict with those set forth in 
the Distribution Agreement, those provisions that provide the greatest 
benefits to the Indemnified Party shall control.

          9.   INFRINGEMENT PROCEEDINGS.  Each Park Place Party shall provide 
Hilton or CRC, as applicable, with prompt written notice of (i) any 
unauthorized uses by third parties of a Licensed Mark, or of confusingly 
similar or diluting trademarks, service marks, trade names, terms or designs, 
which come to the attention of such Park Place Party and (ii) any action 
commenced or threatened against such Park Place Party in connection with its 
use of a Licensed Mark. Each Licensor shall have the right, in its sole 
discretion, to commence infringement or unfair competition actions regarding 
any unauthorized use by third parties of such Licensor's Licensed Mark or any 
confusingly similar or diluting devices.  The Park Place Parties shall 
cooperate with and assist the Licensors in their investigation and 
prosecution of any of the foregoing.

          10.  INJUNCTION.  Each Park Place Party agrees that if application is
made by Hilton or Hilton International CO to reinstate the Injunction, such Park
Place Party shall not oppose or contest such application or take any other
action to interfere with the reinstatement of the Injunction.  Each Park Place
Party shall cooperate, if requested by Hilton and/or Hilton International CO, in
obtaining court approval of any such application and shall execute any documents
required by the court in connection therewith.  If the Injunction is reinstated,
each 

                                      10


Park Place Party shall take all actions necessary to comply with the terms 
and provisions set forth in the Injunction.

          11.  RELATIONSHIP OF PARTIES.  Nothing in this Agreement shall be 
construed to create any relationship among the parties of agency, 
partnership, franchise or joint venturer or render any party liable for any 
debts or obligations incurred by any other party hereto.  No party is 
authorized to enter into agreements for or on behalf of any other party 
hereto, to collect any obligation due or owed to any such party, or to bind 
any other party in any manner whatsoever.

          12.  ASSIGNMENT AND SUBLICENSE.  No Park Place Party may assign its 
rights under this Agreement or sublicense its rights to use either Licensed 
Mark to a third party without the prior written consent of the Licensor of 
such Licensed Mark (which consent may be withheld in the sole discretion of 
such Licensor).  Upon any assignment or sublicense entered into in accordance 
with this Section 12, such assignee or sublicensee shall enter into an 
assignment or sublicense agreement with such Park Place Party, in a form 
reasonably satisfactory to the applicable Licensor, pursuant to which such 
assignee or sublicensee agrees to comply with, and be bound by, the terms of 
this Agreement and acknowledges the status of Hilton and CRC as intended 
third party beneficiaries of such assignment or sublicense agreement.  If 
requested by the applicable Licensor, such assignee or sublicensee shall also 
execute an instrument or instruments pursuant to which such assignee or 
sublicensee shall be bound by, and become a party to, this Agreement.  Any 
purported assignment or sublicense by any Park Place Party not in compliance 
with the terms of this Agreement shall be null and void.  Subject to the 
foregoing, this Agreement shall be binding upon and inure to the benefit of 
the parties and their successors and assigns.

          13.  TERM; TERMINATION OF LICENSE.

               (a)  This Agreement, unless earlier terminated pursuant to 
this Section 13, shall expire upon the later to occur of the expiration (or 
earlier termination) of the Hilton License and the Conrad License.  By mutual 
agreement of the parties, the term of this Agreement may be renewed with 
respect to any License for an extended period to be determined by the parties.

               (b)  During the Initial Term, the Park Place Parties shall be 
required to use the Hilton Mark at each of the Hilton Casino Hotels. 
Thereafter, the Park Place Parties may terminate use of the Hilton Mark at 
any Hilton Casino Hotel by giving the Hilton Parties at least six months' 
written notice of the Park Place Parties' decision to terminate use of the 
Hilton Mark; PROVIDED, HOWEVER, that with respect to the Las Vegas Hilton, 
Reno Hilton and Atlantic City Hilton, the Park Place Parties shall be 
required to use the Hilton Mark for the Extended Term, except the Park Place 
Parties may terminate use of the Hilton Mark if: (i) the  Las Vegas Hilton, 
Reno Hilton and Atlantic City Hilton are sold by the Park Place Parties and 
the Park Place Parties pay the Hilton Parties the present value of the Yearly 
Fee due under the remainder of the Extended Term, discounted back at a six 
percent annual rate or (ii) after the fifth anniversary of the date hereof, 
the Park Place Parties provide the Hilton Parties with at least six months' 
written notice of the Park Place Parties' decision to terminate use of the 
Hilton Mark with respect to the  Las Vegas Hilton, Reno Hilton and Atlantic 
City Hilton, and the Park Place 

                                      11


Parties pay the Hilton Parties the present value of the Yearly Fee due under 
the remainder of the Extended Term, discounted back at a six percent annual 
rate.

               (c)  Notwithstanding any of the foregoing, any party may at 
any time terminate this Agreement in the event of a material breach by any 
other party of any provision herein that has not been cured within ten days 
following the receipt by the breaching party of notice of such breach, 
PROVIDED, HOWEVER, that the availability of such right of termination shall 
not prejudice the terminating party's right to pursue any additional remedies 
at law or in equity with respect to such breach.

          14.  EFFECT OF TERMINATION.

               (a)  Upon the termination of this Agreement, the Park Place
Parties shall:

                    (i)  immediately discontinue use of the Licensed Marks, 
refrain from using any confusingly similar marks, terms or designs, and no 
longer possess any right or interest in the Licensed Marks; and 

                    (ii) if  Hilton requires, cooperate with Hilton to apply 
to the appropriate authorities to cancel from all governmental records the 
recording of this Agreement or to record the termination of this Agreement.

               (b)  Notwithstanding any termination of this Agreement, (i) 
the provisions of Section 2 (Assignment of Marks and Licenses), Section 5 
(Ownership of Marks), Section 6(e) (Limitations on Use of the Licensed 
Marks), Section 8 (Limitation on Liability; Indemnity), Section 15 
(Severability), Section 17 (Specific Performance), Section 18 (Arbitration), 
Section 19 (Choice of Law), Section 20 (Attorneys' Fees) and Section 25 
(Waiver) of this Agreement shall remain in full force and effect in 
perpetuity and (ii) the provisions of Section 14(a) of this Agreement shall 
remain in effect until satisfied in full.

          15.  SEVERABILITY.  The invalidity or partial invalidity or 
unenforceability of any portion of this Agreement shall not affect the 
validity or enforceability of any other portion.  If it is ever held that any 
covenant hereunder is too extensive to permit enforcement of such restriction 
to its fullest extent, each party agrees that a court of competent 
jurisdiction may enforce such covenant to the maximum extent permitted by 
law, and each party hereby consents and agrees that such scope may be 
judicially modified accordingly in any proceeding brought to enforce such 
covenant.

          16.  REMEDIES.  Each of the parties acknowledge and agree that 
money damages would be inadequate relief for any breach or threatened breach 
by the other party of its obligations hereunder, and that upon such breach, 
the non-breaching party or parties, as the case may be, shall be entitled to 
injunctive or other equitable relief for any breach or threatened breach 
thereof.

          17.  SPECIFIC PERFORMANCE.  The parties hereto agree that the 
remedy at law for any breach of this Agreement will be inadequate and that 
any party by whom this Agreement is enforceable shall be entitled to specific 
performance in addition to any other appropriate relief or 

                                      12


remedy.  Such party may, in its sole discretion, apply to a court of 
competent jurisdiction for specific performance or injunctive or such other 
relief as such court may deem just and proper in order to enforce this 
Agreement or prevent any violation hereof and, to the extent permitted by 
applicable laws, each party waives any objection to the imposition of such 
relief.

          18.  ARBITRATION.  The parties hereto agree that any dispute, 
controversy or disagreement between the parties related to the obligations of 
the parties under this Agreement in respect of which resolution cannot be 
reached shall be submitted for mediation and final and binding arbitration in 
accordance with Section 9.14 of the Distribution Agreement, including Section 
9.14(c) thereof regarding the parties' ability to seek specific performance 
or injunctive relief thereof.

          19.  CHOICE OF LAW.  This Agreement shall be construed under and 
entered in accordance with the laws of the State of New York.

          20.  ATTORNEYS' FEES.  If any party commences an action against the 
other with respect to this Agreement, the prevailing party in such action 
shall be entitled to an award of reasonable costs and expenses of mediation, 
arbitration and/or litigation, including reasonable attorneys' fees, to be 
paid by the non-prevailing party.

          21.  EXPENSES.  Except as specifically provided otherwise in this 
Agreement, all fees and expenses incurred in connection with this Agreement 
and the consummation of the transactions contemplated hereby shall be paid by 
Park Place.  In addition, it is understood and agreed that Park Place shall 
pay the legal, recording, filing and out-of-pocket expenditures in connection 
with (a) the filing and recordation of the assignment of the Assigned Marks 
and the License and (b) any accrued and unpaid fees and expenses with respect 
to legal, recording, filing and other expenses related to the Assigned Marks.

          22.  ENTIRE AGREEMENT.  This Agreement (and the exhibit, annexes 
and schedules hereto which are incorporated by reference herein and made part 
hereof) and the Distribution Agreement (including any Ancillary Agreements, 
as such term is defined in the Distribution Agreement) constitute the entire 
agreement and understanding among the parties hereto with respect to the 
subject matter covered by such agreements, and supersedes any prior or 
contemporaneous agreement or understanding related to the subject matter 
hereof and thereof.  To the extent that the terms of this Agreement and 
similar terms of the Distribution Agreement or any Ancillary Agreement are in 
conflict, the interpretation given to the conflicting terms of the 
Distribution Agreement shall govern the interpretation and performance of 
this Agreement.

          23.  AMENDMENTS.  This Agreement may not be amended, supplemented 
or modified in any respect except by written agreement among the parties, 
duly signed by their respective authorized representatives.

          24.  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, each of which shall be deemed an original, and all such 
counterparts together shall constitute but one and the same instrument.

          25.  WAIVER.  Park Place may specifically waive any breach of this 
Agreement by the Hilton Parties and Hilton may waive any breach of this 
Agreement by a Park Place Party; 

                                      13


PROVIDED, HOWEVER, that no such waiver shall be deemed effective unless in 
writing, signed by the waiving party, and specifically designating the breach 
waived.  No waiver shall constitute a continuing waiver of similar or other 
breaches.

          26.  NOTICES.  Any notice required or permitted hereunder shall be 
in writing and shall be deemed received (a) upon personal delivery, if so 
delivered, (b) upon three (3) business days after having been deposited in 
the United States mail, first class, postage prepaid, return receipt 
requested, or (c) on the next business day if sent by nationally recognized

the Hilton Mark or Conrad Mark, as the case may be, in such market within six 
months and of its decision to withdraw from Hilton Reservations Worldwide and
