and Records will be kept at the facilities of Borrower.

Security Agreement.

         3.4 Chief Executive Office. The address of Borrower set forth in the

4.       COVENANTS OF BORROWER

         4.1 Maintenance. Borrower shall keep and maintain the Collateral in
good condition and repair and shall not use the Collateral in violation of any
provision of this Agreement or any applicable statute, ordinance or regulation
or any policy of insurance insuring the Collateral.

                                       3
<PAGE>
         4.2 Insurance. To the extent insurable, Borrower will keep the
Collateral insured against damage and loss, in amounts and by insurance
companies, acceptable to Lenders. Borrower understand that the policy must
provide that any insurance proceeds will be paid to Lenders and shall provide
Agent with not less than 30 days' prior written notice of termination,
cancellation or non-renewal. The Borrower will deliver the policy to Lenders
upon Lenders' request.

         4.3 Payments of Charges. Borrower shall pay when due all taxes,
assessments and other charges which may be levied or assessed against the
Collateral.

         4.4 Fixtures and Accessions. Borrower shall prevent any portion of the
Collateral that is not a fixture from being or becoming a fixture and shall
prevent any portion of the Collateral from being or becoming an accession to
other goods that are not part of the Collateral.

         4.5 Notice to Lenders. Borrower shall give Lenders 45 days' prior
written notice of any change: (i) in the location of any of the facilities of
Borrower; (ii) in the location of the Collateral, including, without limitation,
the Books and Records; or (iii) of the names under which it does business.

         4.6 Inspections. Lender or its agents may inspect the Collateral at
reasonable times and may enter into any premises where the Collateral is or may
be located.

         4.7 Payment of Charges. If Borrower fails to pay any taxes,
assessments, expenses or charges, or fails to keep all of the Collateral free
from other security interests, encumbrances or claims except for Permitted
Liens, or fails to keep the Collateral in good condition and repair, or fails to
procure and maintain insurance thereon, or to perform otherwise as required
herein, Lender may advance the monies necessary to pay the same, to accomplish
such repairs, to procure and maintain such insurance or to so perform. Lender is
hereby authorized to enter upon any property in the possession or control of
Borrower for such purposes.

         4.8 Rights and Powers. All rights, powers and remedies granted Lender
herein, or otherwise available to Lender, are for the sole benefit and
protection of Lender, and Lender may exercise any such right, power or remedy at
its option and in its sole and absolute discretion without any obligation to do
so. In addition, if under the terms hereof, Lender is given two or more
alternative courses of action, Lender may elect any alternative or combination
of alternatives at its option and in its sole and absolute discretion. All
monies advanced by Lender under the terms hereof and all amounts paid, suffered
or incurred by Lender in exercising any authority granted herein, including,
without limitation, attorneys' fees, shall be added to the Secured Obligations,
shall be secured by the Collateral, shall bear interest at the highest rate
payable on any of the Secured Obligations until paid, and shall be due and
payable by Borrower to Lender immediately without demand.

5.       USE OF COLLATERAL BY BORROWER

         Until the occurrence of an Event of Default, Borrower may use the
Collateral in any lawful manner in the ordinary course of Borrower's business.
Borrower cannot sell the Collateral except for inventory in the ordinary course
of Borrower's business.

                                       4
<PAGE>
6.       COLLATERAL IN THE POSSESSION OF LENDER

         6.1 Care. Lenders shall use such reasonable care in handling,
preserving and protecting the Collateral in their possession as they use in
handling similar property for their own account. Lenders, however, shall have no
liability for the loss, destruction, or disappearance of any Collateral unless
there is affirmative proof of a lack of due care. A lack of due care shall not
be implied solely by virtue of any loss, destruction or disappearance.

         6.2 Preservation of Collateral. Borrower shall be solely responsible
for taking any and all actions to preserve rights against all Obligors. Lenders
shall not be obligated to take any such actions whether or not the Collateral is
in Lenders' possession. Borrower waives presentment and protest with respect to
any instrument included in the Collateral on which Borrower is in any way liable
and waives notice of any action taken by Lenders with respect to any instrument,
document or chattel paper included in any Collateral that is in the possession
of Lenders.

7.       EVENTS OF DEFAULT; REMEDIES

         7.1 Events of Default. The occurrence of any of the following events or
conditions shall constitute an "Event of Default":

                  (a) the Borrower fails to pay any of the principal, interest
or other charges on the Note at the time such payment is required to be made
under the Note, including any applicable grace period therein.;

                  (b) the Borrower fails to perform any promise contained in
this Agreement or in the Note or other agreement relating to the Loan, or in any
other promissory note or agreement between Borrower and Lenders;

                  (c) any statement made by the Borrower in connection with the
Loan proves to have been misleading when it was made; or

                  (d) Lenders acting through Agent consider themselves insecure
(that is, if anything happens that, in Lenders' judgment, makes it unlikely the
Loan will be paid)

         7.2 Remedies. Upon the occurrence of any Event of Default, and at any
time while such Event of Default is continuing, Lender shall have the right to
declare all or any part of the Secured Obligations to be immediately due and
payable, and the same, with all costs and charges, shall be collectible
thereupon by action at law.

         7.3 Purchase of Collateral. Lenders, so far as may be lawful, may
purchase all or any part of the Collateral offered at any public or private sale
made in the enforcement of Lenders' rights and remedies hereunder.

         7.4 Notice. Any demand or notice of sale, disposition or other intended
action hereunder or in connection herewith, whether required by the UCC or
otherwise, shall be deemed to be commercially reasonable and effective if such
demand or notice is given to Borrower at

                                       5
<PAGE>
least 10 days prior to such sale, disposition or other intended action, in the
manner provided herein for the giving of notices.

         7.5 Additional Remedies. In addition to any remedies provided herein
for an Event of Default, Lenders shall have all the rights and remedies afforded
a secured party under the UCC and all other legal and equitable remedies allowed
under applicable law. No failure on the part of Lenders to exercise any of its
rights hereunder arising upon any Event of Default shall be construed to
prejudice its rights upon the occurrence of any other or subsequent Event of
Default. No delay on the part of Lenders in exercising any such rights shall be
construed to preclude Lenders from the exercise thereof at any time while that
Event of Default is continuing. Lenders may enforce any one or more rights or
remedies hereunder successively or concurrently. By accepting payment or
performance of any of the Secured Obligations after its due date, Lenders shall
not thereby waive the agreement contained herein that time is of the essence,
nor shall Lenders waive either their right to require prompt payment or
performance when due of the remainder of the Secured Obligations or their right
to consider the failure to so pay or perform an Event of Default.

8.       MISCELLANEOUS PROVISIONS

         8.1 Power of Attorney. Borrower hereby appoints Agent, on behalf of
Lenders, as its true and lawful attorney-in-fact, with full power of
substitution to do the following: (i) to demand, collect, receive, receipt for,
sue and recover all sums of money or other property which may now or hereafter
become due, owing or payable from the Collateral; (ii) to execute, sign and
endorse any and all claims, instruments, receipts, checks, drafts or warrants
issued in payment for the Collateral; (ii) to settle or compromise any and all
claims arising under the Collateral, and, in the place and stead of Borrower to
execute and deliver its release and settlement for the claim; (iv) to file any
claim or claims or to take any action or institute or take part in any
proceedings, either in its own name or in the name of Borrower, or otherwise,
which in the discretion of Agent may seem to be necessary or advisable; and (v)
to execute any documents necessary to perfect or continue the Security Interest.

Secured Obligations, and the authority hereby conferred is and shall be
irrevocable and shall remain in full force and effect until renounced by Agent
or Agent is replaced by a Successor Agent.

         8.2 Indemnification. In addition to the indemnities contained in the

Agent, Lenders, and their affiliates and their respective successors, assigns
and shareholders and the directors, officers, employees, agents and attorneys of
the foregoing (collectively, the "Indemnified Parties") for, from and against
any and all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, expenses and disbursements of any kind or
nature whatsoever (including, without limitation, the fees and disbursements of
counsel for such Indemnified Parties in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether or not
such Indemnified Parties are designated parties thereto) that may be imposed on,
incurred by, or asserted against the Indemnified Parties, in any manner relating
to or arising out of this Agreement or the Loan Documents (the "Indemnified
Liabilities"); provided, however, that Borrower shall have no obligation to an
Indemnified Party hereunder with respect

                                       6

misconduct of that Indemnified Party.

         8.3 Other Security. The acceptance of this Agreement by Lenders shall
not be considered a waiver of or in any way to affect or impair any other
security that Lenders may have, acquire simultaneously herewith, or hereafter
acquire for the payment or performance of the Secured Obligations, nor shall the
taking by Lenders at any time of any such additional security be construed as a
waiver of or in any way to affect or impair the Security Interest. Lenders may
resort, for the payment or performance of the Secured Obligations, to their
several securities therefor in such order and manner as it may determine.

         8.4 Actions by Lenders. Without notice or demand, without affecting the
obligations of Borrower hereunder, and without affecting the Security Interest
or the priority thereof, Lenders, from time to time, may: (i) extend the time
for payment of all or any part of the Secured Obligations, accept a renewal note
therefor, reduce the payments thereon, release any person liable for all or any
part thereof, or otherwise change the terms of all or any part of the Secured
Obligations; (ii) take and hold other security for the payment or performance of
the Secured Obligations and enforce, exchange, substitute, subordinate, waive or
release any such security; (iii) join in any extension or subordination
agreement; or (iv) release any part of the Collateral from the Security
Interest.

         8.5 Waivers. Borrower waives and agrees not to assert: (i) any right to
require Lenders to proceed against any guarantor, to proceed against or exhaust
any other security for the Secured Obligations, to pursue any other remedy
available to Lenders, or to pursue any remedy in any particular order or manner;
(ii) the benefits of any legal or equitable doctrine or principle of
marshalling; (iii) the benefits of any statute of limitations affecting the
enforcement hereof; (iv) demand, diligence, presentment for payment, protest and
demand, and notice of extension, dishonor, protest, demand and nonpayment,
relating to the Secured Obligations; and (v) any benefit of, and any right to
participate in, any other security now or hereafter held by Lenders.

                             FIRST AMENDMENT TO THE
                    STARWOOD HOTELS & RESORTS WORLDWIDE, INC.
                   1999 LONG-TERM INCENTIVE COMPENSATION PLAN

      Amendment, dated as of August 1, 2001, to the Starwood Hotels & Resorts
Worldwide, Inc. 1999 Long-Term Incentive Compensation Plan (the "Plan").

      WHEREAS, the Board of Directors of Starwood Hotels & Resorts Worldwide,
Inc. (the "Corporation") has determined that it is advisable and in the best
interests of the Corporation that the Plan be amended as set forth in this First
Amendment.

NOW, THEREFORE, the Corporation agrees, for its benefit and the benefit of the
Plan Participants, as follows:

      1.    Article 2 of the Plan is hereby amended by adding the following
            defined term and renumbering the sections following the new
            definition accordingly:

            "2.29 "Retirement" means termination of employment other than for
            Cause after a Participant has reached the age of 55 years and has
            completed at least five years of service (full-time or full-time
            equivalent), provided that the sum of the age of Participant plus
            the number of years of service (full-time or full-time equivalent)
            is equal to at least 65."

      2.    Section 3.2 is hereby amended by capitalizing the terms "retirement"
            and "disability" that appear in such Section of the Plan. Such terms
            shall appear as "Retirement" and "Disability."

      3.    Article 6 is hereby amended by adding the following paragraph (f)
            under Section 6.8 of the Plan:

            "(f) Retirement. Unless otherwise specified in the Award Agreement
            relating to an Option, upon Retirement, a Participant's Option shall
            continue to vest as set forth in the Award Agreement relating to
            such Option and the Participant may exercise any vested portion of
            an Option up until and including the earliest to occur of (i) the
            fifth anniversary of the Participant's effective date of Retirement
            and (ii) the expiration date of the term of such Option; provided,
            however, that any unvested portion of an Option not exercised by the
            fifth anniversary of the Participant's effective date of Retirement
            shall be canceled. The foregoing notwithstanding, during the five
            year period beginning from the date of Retirement, all vested but
            unexercised Options and all unvested Options held by Participant
            will be canceled in the event Participant accepts any employment,
            assignment, position of responsibility, or acquires any ownership
            interest (other than holding and making investments in common equity
            securities of any corporation, limited partnership or other entity
            that has its common equity securities traded in a generally
            recognized market, provided such equity interest therein does not
            exceed 5% of the
<PAGE>
            outstanding shares or equity interests in such corporation, limited
            partnership or other entity), which involves the Participant's
            participation in a hotel and leisure company engaged in the
            operation of owned hotels, management of hotels, franchising hotels,
            development and operation of vacation ownership resorts or the
            marketing and selling of vacation ownership interests."

      4.    Article 8 is hereby amended by adding the following paragraph (c)
            under Section 8.7:

            "(c) Retirement. Unless otherwise specified in the Award Agreement
            relating to a Restricted Stock Award, upon Retirement, a Restricted
            Stock Award will continue to vest as set forth in the Award
            Agreement relating to such Restricted Stock Award, provided that any
            unvested portion of a Restricted Stock Award will be canceled on the
            fifth anniversary of the Participant's effective date of Retirement.
            The foregoing notwithstanding, during the five year period beginning
            from the date of Retirement, all unvested Restricted Stock Awards
            held by Participant will be canceled in the event Participant
            accepts any employment, assignment, position or responsibility, or
            acquires any ownership interest (other than holding and making
            investments in common equity securities of any corporation, limited
            partnership or other entity that has its common equity securities
            traded in a generally recognized market, provided such equity
            interest therein does not exceed 5% of the outstanding shares or
            equity interests in such corporation, limited partnership or other
            entity), which involves the Participant's participation in a hotel
            and leisure company engaged in the operation of owned hotels,
            management of hotels, franchising hotels, development and operation
            of vacation ownership resorts and the marketing or selling of
            vacation ownership interests."

      5.    The first paragraph of Section 9.5 shall be amended in its entirety
            as follows:

            "9.5 Termination of Employment Due to Death, Disability or
            Retirement. Unless determined otherwise by the Committee and set
            forth in the Participant's Award Agreement, in the event the
            employment of a Participant is terminated by reason of death,
            Disability or Retirement, the Participant shall receive a payout of
            the Performance Units/Shares which is prorated, as specified by the
            Committee its discretion."

      6.    All capitalized terms used in this First Amendment and not otherwise
            defined herein shall have the respective meanings assigned thereto
            in the Plan.

      7.    Except as otherwise specifically set forth herein, all terms and
            provisions of the Plan shall remain in full force and effect and
            shall be unmodified by the effectiveness of this First Amendment.

         IN WITNESS WHEREOF, Starwood Hotels & Resorts Worldwide, Inc. has
      adopted this First Amendment to the 1999 Long-Term Incentive Compensation
