AMENDMENT
     Amendment (the “Amendment”) dated as of December 6, 2007 to Employment
Agreement (the “Agreement”) dated as of July 18, 1999 between Vistana, Inc., a
Florida corporation (currently known as Starwood Vacation Ownership Inc., the
“Company”), and Raymond L. Gellein, Jr. (“Employee”) and certain other
agreements entered into with Employee including but not limited to those listed
on Schedule A hereto.
WHEREAS, this Amendment is being entered into in connection with the retirement
of Employee; and
WHEREAS, the parties desire to enter into this Amendment upon the terms and
conditions hereafter set forth.
NOW, THEREFORE, in consideration of the foregoing, of the mutual covenants and
agreements herein contained and for other good and valuable consideration, the
receipt, adequacy and sufficiency of which are hereby acknowledged, the parties,
intending to be legally bound, hereby agree as follows:

  1.   Defined Terms. All capitalized terms not otherwise defined in this
Amendment shall have the meaning ascribed to them in the Agreement.     2.  
Term. Section 3 of the Agreement is hereby amended by deleting clause (b)(iv)
thereof and replacing it with the following:

iv) the date upon which Employee effects a Voluntary Termination (other than due
to Retirement) or terminates employment for Good Reason (it being understood
that the date of termination shall be the date upon which Employee provides the
Company written notice of such termination); or
v) the effective date of Employee’s Retirement.
The effective date of Employee’s Retirement shall be the earlier of
(a) March 31, 2008 or (b) the date the Company determines that the transition of
Employee’s duties to another employee have been completed and gives written
notice thereof to Employee. For purposes hereof, “Retirement” shall be defined
as such term is defined as of the date hereof under the Starwood Hotels &
Resorts Worldwide, Inc. 2004 Long-Term Incentive Compensation Plan. The parties
agree that Employee is currently eligible for Retirement under such definition
and for purposes of any other Starwood plans and agreements affecting Employee
that use the term “Retirement”. In the event of Employee’s termination of

--------------------------------------------------------------------------------

 

employment due to death or Permanent Disability after the date of this Agreement
but prior to the effective date of Retirement, compensation shall not be
determined under Section 8(e) of the Agreement but rather shall be treated as a
Retirement with the effective date of the Retirement being the date of death or
Permanent Disability with compensation as provided for in this Amendment
(provided that the bonus payment will be computed as if Employee had been
employed through December 31, 2007 and there being no participation in the
Annual Incentive Plan in respect of 2008). Except as provided in the foregoing
sentence and in paragraph 4(e) below, Employee’s death or Permanent Disability
prior to the effective date of Retirement, shall not affect Employee’s
entitlement under any other Starwood benefit plans or agreements.

  3.   Salary, Bonus and Benefits. Notwithstanding any other provision of the
Agreement, including but limited to Section 8 thereof:

  a)   Employee shall continue to receive an amount equal to his Adjusted Base
Salary (less applicable deductions) as currently in effect as well as all
current benefits (other than future equity based awards) until the effective
date of his Retirement pursuant to Section 3(b)(v), it being understood that
there shall be no continuation of his Adjusted Base Salary after such date.    
b)   Employee shall not participate in any Annual Incentive Plan in respect of
2008.     c)   In respect of payments for the 2007 performance year under the
Annual Incentive Plan for Certain Executives (the “AIPCE”): (i) pursuant to
Section 5.1(a) of the AIPCE, no portion of any bonus payment will be deferred;
(ii) subject to satisfaction of the threshold Performance Measure (as defined in
the AIPCE) applicable to Employee’s bonus payment, the individual component of
Employee’s bonus payment shall be calculated at no less than target with the
team component computed based on team performance; and (iii) in the event the
effective date of Employee’s Retirement occurs prior to December 31, 2007, the
bonus shall not be pro rated.     d)   As of the Termination Date, Employee
shall terminate participation in the Company’s and Parent’s employee benefit
plans and arrangements (except to the extent required by COBRA or other
applicable law).

  4.   Equity Arrangements.

  a)   The Restricted Stock Award Agreement (the “2007 RS Agreement”) for the
grant made on February 28, 2007 is amended:

  1.   by deleting all words in paragraph 2(b) after the words “account of the
Participant” in the first sentence thereof and replacing it with the following:
        “upon vesting shall be paid to the Participant no later than March 15,
2008.”; and

2

--------------------------------------------------------------------------------

 

  2.   by deleting the definition of “Qualifying Service Period” contained in
Section 4(c) thereof and replacing it with the following:         “Qualifying
Service Period” which is a period of continuous employment extending from the
Grant Date until the first day the Participant is currently eligible for
Retirement”

  b)   The Non-Qualified Stock Option Award Agreement (the “2007 Option
Agreement”) for the grant made on February 28, 2007 is amended by deleting the
first sentence of Section 2.2(e) thereof and replacing it with the following:

In the case of an Optionee who is or becomes eligible for Retirement prior to
when the Option is 100% exercisable, the Option shall be 100% vested not later
than a period of continuous employment extending from the Option Date until the
first day the Participant is currently eligible for Retirement and shall become
exercisable in its entirety on the date commencing 18 months from the Option
Date.

  c)   The termination or forfeiture provisions contained in Section 4(c) of the
2007 RS Agreement and Section 2.2(e) of the 2007 Option Agreement and comparable
Retirement provisions in all other equity grant agreements with the Employee are
amended such that in addition to the triggering events set forth therein (but
without extending the duration of such restrictions), a termination or
forfeiture shall be triggered upon a breach by Employee of Section 10 of the
Agreement as amended hereby.     d)   The Restricted Stock Award Agreement for
the grant made on February 7, 2006 is amended by deleting all words in paragraph
2(b) after the words “account of the Participant” in the first sentence thereof
and replacing it with the following:

      “upon vesting shall be paid to the Participant no later than March 15,
2008.”

  e)   If the Employee’s employment terminates by reason of death or Disability
(as defined in the 2007 Option Agreement) rather than Retirement after the date
of this Agreement but prior to the effective date of Retirement, such
termination shall nonetheless be treated as a Retirement for purposes of the
2007 Option Agreement with the date of death or Disability being

3

--------------------------------------------------------------------------------

 

      deemed the effective date of Retirement. Similarly, in the case of all
other option grant agreements with Employee (including the option grant
agreements listed on Schedule A), the exercise period for options shall continue
to be determined under the applicable Retirement provisions as though Employee
had retired on the date of death or Disability. This provision is not applicable
to any of Employee’s Restricted Stock Agreements.

  5.   Covenant Not to Compete. Section 10(d) of the Agreement is amended by
adding the following after the last word of such clause:

or to any other person, entity or group (whether or not involved in the
foregoing activities) that is evaluating, proposing or financing the acquisition
of all or any part of Parent.

  6.   Chairman Emeritus. In recognition of Employee’s extraordinary
contributions to the success of the Company, until Employee’s Retirement, he
shall have the title “Chairman Emeritus” of the Company. Such title is an
honorary title and shall not bestow any voting, attendance or other rights.    
7.   Ratification. All of the sections, terms, covenants and conditions
contained in the Agreement and the other agreements and arrangements referred to
in this Amendment or otherwise entered into with Employee, except as modified by
this Amendment, shall remain unmodified and of full force and effect and are
hereby ratified and affirmed by Employee, Company and Parent including but not
limited to the Cash Bonus Award Agreement dated September 19, 2007.     8.  
Binding Effect. This Amendment shall be binding upon and inure to the benefit of
the Parties hereto, their respective successors and assigns.     9.   Governing
Law. The relevant Governing Law provisions of the Agreement and of each of the
other agreements amended hereby shall govern the provisions of this Amendment
that relate to each such agreement. To the extent a provision of this Amendment
does not amend a previous agreement, such provisions shall be governed by the
laws of the State of New York.     10.   Counterparts. This Amendment may be
executed in two or more counterparts and via facsimile, each of which shall be
deemed an original but all of which taken together shall constitute one and the
same instrument.     11.   Effective Date. This Amendment shall be in full force
and effect as a binding obligation of Employee, Parent and the Company from and
after the date of this Amendment.
