a Delaware corporation ("PHI"), and VISTANA, INC., a Florida corporation
("Vistana").


                                R E C I T A L S:


          A.  PHI and Vistana Development, Ltd., a Florida limited partnership
("VDL"), are parties to a certain Exclusive Joint Venture Agreement dated
December 24, 1996 (the "Initial Agreement"), as amended by a certain First
Amendment to Exclusive Joint Venture Agreement dated February 7, 1997 ("First
Amendment") and a certain Second Amendment to Exclusive Joint Venture Agreement
dated February 27, 1997 ("Second Amendment") (the Initial Agreement as amended
by the First Amendment and Second Amendment is hereinafter referred to as the
"Amended Agreement") pursuant to which, among other things, the parties have
agreed to jointly develop Vacation Resorts.

          B.  VDL has heretofore transferred and assigned all of its right,
title and interest in and under the Amended Agreement to Vistana, and Vistana
has assumed all of the obligations of VDL under the Amended Agreement.

          C.  PHI and Vistana desire to amend the Amended Agreement as provided
herein.

          NOW, THEREFORE, in consideration of the foregoing, and of other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending legally to be bound, have agreed and
by these presents do amend the Amended Agreement and agree as follows:

          1.  Defined Terms. All capitalized terms used herein shall have the
     same meanings ascribed to them in the Amended Agreement except as otherwise
     defined herein to the contrary or unless the context requires otherwise.

          2.  Acknowledgment of Satisfaction of Conditions. The parties
     acknowledge and agree that (a) the parties have approved the Five Year
     Plan, (b) the parties have approved the form of (i) Sales and Marketing
     Agreement, (ii) Franchise Agreement (consisting of a License Agreement
     between Promus and the property developer and a License Agreement between
     Promus and the association manager), (iii) PHI Management Agreement
     (consisting of a Hospitality Management Agreement between Promus and the
     property developer, and a Hospitality

 
     Submanagement Agreement between the association manager and Promus), (iv)
     Non-Venture Franchise Agreement (consisting of a License Agreement between
     Promus and the property developer and a License Agreement between Promus
     and the association manager) and (v) Non-Venture Management Agreement
     (consisting of a Hospitality Management Agreement between Promus and the
     property developer and a Hospitality Submanagement Agreement between Promus
     and the association manager). The parties have also executed and delivered
     the form of Non-Venture Franchise Agreement with respect to Vistana's
     Vacation Resorts in Myrtle Beach and Kissimmee and a Non-Venture Management
     Agreement with respect to Vistana's Vacation Resort in Myrtle Beach. The
     parties hereby acknowledge and agree that the provisions of Section
     15(a)(ii) of the Amended Agreement are null and void and of no force or
     effect.

          3.  Amendments to Section 15 of the Second Amended Agreement. Section
     15 of the Amended Agreement is hereby amended as follows:

          A.  By changing subparagraph "(c)" thereof to subparagraph "(d)" and
     by adding the following new subparagraph (c):

               "(c) Change-In-Control. In the event of a "Change-In-Control" of
          either PHI or Vistana (the "Applicable Party"), either party shall
          have the right to terminate this Agreement by delivery of written
          notice thereof to the other party at any time after such Change-In-
          Control and prior to the date that is ninety (90) days after the
          Applicable Party shall have notified the other party in writing of
          such Change-In-Control. For purposes hereof, a "Change-In-Control"
          shall mean a transfer by the Applicable Party of all or substantially
          all of its assets to a competitive hospitality company (as hereinafter
          defined) or a competitive hospitality company acquires through one or
          more series of transactions more than fifty percent (50%) of any class
          of issued and outstanding capital stock of the Applicable Party or of
          any entity which controls the Applicable Party and such competitive
          hospitality company has the ability to elect a majority of the
          directors of the Applicable Party or of any entity which controls the
          Applicable Entity. The term "competitive hospitality company" shall
          mean any person or entity which, directly or indirectly, is in the
          business of operating or franchising hotels, resorts or other
          transient lodging facilities or controls, is controlled by or is under
          common

                                      -2-

 
          control with, any person or entity which, directly or indirectly, is
          in the business of operating or franchising hotels, resorts or other
          transient lodging facilities."

          B.  By deleting subparagraph (d)(i) of Section 15 (formerly
     subparagraph (c)(i) of Section 15) and by substituting the following:

          "(i) any Venture then in existence shall remain in existence and
          continue to be governed by its Venture Agreement and other applicable
          Transaction Documents and any franchise, license or management
          relationship in existence shall remain in existence and continue to be
          governed by the applicable Franchise Agreement, Management Agreement
          or other applicable Transaction Documents; and"

          4.  Addition of New Section 24. A new Section 24 is hereby added to
     the Amended Agreement as follows:

          "24. Non-Solicitation. Each party hereto agrees, during the Term of
          this Agreement, that such party and such party's Affiliates shall not,
          directly or indirectly, solicit for employment or hire any person
          employed by the other party or any of such other party's subsidiaries
          or Affiliates at a position of Manager or higher."

          5.  Addition of New Section 25. A new Section 25 is hereby added to
     the Amended Agreement as follows:

          "25. Acknowledgment of Exclusivity. The parties hereto acknowledge and
          agree that nothing contained in any Franchise Agreement or Non-Venture
          Franchise Agreement (including, without limitation, the provisions of
          Paragraph 2 thereof) is intended to or shall limit or modify the
          exclusivity obligations of the parties to each other hereunder
          including, without limitation, the obligations of the parties to each
          other under Section 4 hereof."

          6.  Acknowledgment. Promus acknowledges that VDL has assigned, and
     Vistana has assumed, VDL's rights and obligations under the Amended
     Agreement pursuant to Section 13 of the Amended Agreement. Accordingly, VDL
     is hereby released from any and all obligations arising subsequent to the
     date of such assignment.

          7.  Integration of Amendment. Except as provided herein, the Amended
     Agreement is hereby confirmed and the

                                      -3-

 
     terms and provisions thereof, unless modified herein, shall remain in full
     force and effect.

          8.  Counterparts. This Third Amendment may be executed in several
     counterparts and all so executed shall constitute one agreement binding on
     the parties hereto, notwithstanding that all the parties are not
     signatories to the original or the same counterpart.

     IN WITNESS WHEREOF, the parties hereto have executed this Third Amendment,
or have caused this Third Amendment to be duly executed on their respective
behalf by their respective officers thereunto duly authorized, as of the day and
year first above written.
