               MASTER VISTANA RESORT CONSTRUCTION LOAN FACILITY
               ------------------------------------------------

     This MASTER VISTANA RESORT CONSTRUCTION LOAN FACILITY (this "Agreement")
dated as of October 9, 1998, is made by and between HELLER FINANCIAL, INC., a
Delaware corporation ("Lender"), and VISTANA, INC., a Florida corporation
("Vistana").

                               R E C I T A L S:
                               - - - - - - - - 

     A.  All capitalized terms used herein shall have the meanings ascribed
thereto in the Appendix attached hereto and made a part hereof by this
reference.

     B.  Vistana, directly or through one or more of its subsidiaries, is in the
business of acquiring, constructing, renovating and developing certain Resorts
for the purpose of selling Intervals therein.

     C.  Upon satisfaction of the terms and conditions set forth herein, Lender
may extend financing from time to time to certain Eligible Vistana Subsidiaries,
the proceeds of which will be used to acquire, construct, renovate and develop
certain Eligible Resorts, the first of which is Lakeside Terrace Condominiums
located in Avon, Colorado, for which Resort Loan Documents shall be executed as
of the date hereof the form of which Resort Loan Documents shall be the basis
for execution of future Resort Loan Documents for future Eligible Resorts
hereunder, subject to modifications as required on a resort by resort basis.

     D.  The second Eligible Resort hereunder which is hereby approved by Lender
is the Embassy Vacation Resort located in Scottsdale, Arizona for which Resort
Loan Documents shall be prepared and executed subsequent to the Closing of the
Resort Loan for the Lakeside Terrace Condominiums.

     E.  Vistana has agreed to guarantee all of the obligations of such Eligible
Vistana Subsidiaries under this Agreement and the other Resort Loan Documents,
including, without limitation, all of the obligations of the Eligible Vistana
Subsidiaries with respect to any financing provided from time to time by Lender.

     NOW, THEREFORE, in consideration of the foregoing premises and the
agreements, provisions and covenants herein contained, Vistana and Lender agree
as follows:

SECTION 1.    EXTENSION OF FINANCING

     1.1    Financing Generally.
            ------------------- 

            (a) Extension of Resort Loans. During the Eligibility Period but
                -------------------------    
subject to the requirements of this Section 1.1 and the requirements of Sections
1.2, 1.3 and 2
<PAGE>
 
hereof,  Lender shall extend Resorts Loans to Eligible Vistana Subsidiaries
identified from time to time by Vistana to Lender as being the owners and
developers of particular Eligible Resorts.  Each such Resort Loan shall

          (i)    be made to an Eligible Vistana Subsidiary that is the owner and
developer of an Eligible Resort whose Resort Development Costs are to be
financed, in whole or in part, by such Resort Loan;

          (ii)   be disbursed in a series of Resort Advances during the then
remaining unexpired portion of the Eligibility Period to pay the Resort
Development Costs incurred or to be incurred by such Eligible Vistana Subsidiary
in acquiring, constructing, renovating and developing such Eligible Resort (each
such Resort Advance shall relate to particular line item or items identified in
the Approved Development Budget and Completion Schedule for such Resort; no more
than two Resort Advances (plus one addition Resort Advance of the Interest
Reserve) shall be made in any calendar month);

          (iii)  shall have a final maturity date of seven (7) years from the
Facility Closing Date inclusive of a three (3) year Eligibility Period;
provided, however, that with respect to a particular Resort Loan, such final
maturity date will be the projected date on which such Resort Loan is required
to be amortized to a zero balance based on the agreed upon amortization schedule
for such Resort Loan, subject to extension for up to ninety (90) days in the
event completion of the subject improvements is delayed beyond the applicable
"Completion Date" as a result of Force Majeure as such term is defined in the
applicable Resort Loan Documents;

          (iv)   bear interest at the Interest Rate in effect from time to time
(which interest shall be computed on the unpaid principal balance which exists
from time to time with respect to each Resort Advance under such Resort Loan
only from the date on which such Resort Advance is made and shall be paid by
such Eligible Vistana Subsidiary to Lender on a monthly basis as provided in the
applicable construction loan agreement or promissory note for such Resort Loan);

          (v)    be guaranteed in full by Vistana and be secured by all right,
title and interest of such Eligible Vistana Subsidiary in and to the Eligible
Resort related to such Resort Loan, and in and to all leases, rents, products
and proceeds in respect thereof in accordance with the terms and description of
collateral set forth in the Resort Loan Documents; and

          (vi)   be otherwise governed by the Resort Loan Documents for such
Resort Loan; provided, that, in no event shall the maximum principal amount
             --------
available under such Resort Loan at the time of the initial extension thereof
exceed the Resort Loan Limit determined at such time; it is the intention of
Lender and Vistana that this Master Vistana Resort Construction Loan Facility is
a revolving credit facility pursuant to which Vistana or the Eligible Vistana
Subsidiary may borrow, repay and reborrow principal in an

<PAGE>
 
amount not to exceed the maximum loan amount set forth in Section 1.6 below;
provided, however, each Resort Loan described herein is a term Resort Loan and
not a revolving credit facility and if an Eligible Resort is to be developed in
successive phases, a Resort Loan shall be extended separately for each agreed
upon phase. Each such separate Resort Loan for an Eligible Resort may be
referred to herein from time to time as tranche "A," "B," "C," etc. with respect
to each successive phase of an Eligible Resort.

          (b)   Resort Loan Documents. On or prior to the Resort Loan Closing
                ---------------------
Date for each Resort Loan, Lender and the Eligible Vistana Subsidiary for such
Resort Loan shall enter into the Resort Loan Documents for such Resort Loan.

     1.2  Requests for Financing.  During the Eligibility Period, Vistana
          ----------------------                                           
shall have the right to request Lender to make one or more Resort Loans with
respect to an Eligible Resort.  Each such request shall be made not less than
thirty (30) days and not more than one hundred twenty (120) days prior to the
Resort Loan Closing Date requested by Vistana for such Resort Loan, shall
identify the Eligible Vistana Subsidiary and the Eligible Resort in respect of
such requested Resort Loan and shall be substantially in the form of SCHEDULE

          ---------                                                          
existing and in good standing under the laws of the State of Florida with its
principal place of business at Orlando, Florida.  Vistana is authorized to
transact business in the State of Florida and in each other state where the
failure to so comply would have a Material Adverse Effect.

     4.2  Authorization and Enforceability.
          --------------------------------   

          (a) Execution.  This Agreement has been duly authorized, executed and
              ---------                                                        
delivered and constitutes the duly authorized, valid and legally binding
obligations of Vistana, enforceable against Vistana in accordance with its
terms.

          (b) Other Agreements.  The execution, delivery and compliance with the
              ----------------                                                  
terms and provisions of this Agreement, will not (i) to the best of Vistana's
knowledge, violate any applicable law or regulation, order or other decree of
any court or governmental entity, or (ii) conflict or be inconsistent with, or
result in any default under, any contract, agreement or commitment to which

of Vistana and its consolidated subsidiaries have been delivered to Lender and

of such Persons as of the date or dates thereof and for the periods covered
thereby.  Lender acknowledges that Vistana's Form 10-Q and 10-K quarterly and
annual financial statements are acceptable to Lender to satisfy the annual and
quarterly consolidated financial statements requirements for Vistana, Inc.

default of any order of any court or any applicable requirement of any
Governmental Authority which default would have a Material Adverse Effect.
