and accompanied by undated stock powers duly executed in blank in the case of
Stock, Limited Liability Company Interests or Partnership Interests or such
other instruments of transfer as are reasonably acceptable to the Pledgee, and
will promptly thereafter deliver to the Pledgee a certificate executed by any
Authorized Officer of such Pledgor describing such Securities and certifying
that the same have been duly pledged with the Pledgee hereunder. Subject to the
last sentence of Section 2(a) hereof, any pledge of Voting Stock of any Foreign
Corporation shall be subject to the provisions of part (A) of the proviso to
clause (i)(y) of Section 2(a) hereof.

            3.3. Uncertificated Securities. If any Securities (whether now owned
or hereafter acquired) are uncertificated securities, the respective Pledgor
shall promptly notify the Pledgee
<PAGE>   10
thereof, and shall promptly take all actions required to perfect the security
interest of the Pledgee under applicable law (including, in any event, under
Sections 8-106 and 9-115 of the New York UCC, if applicable). Each Pledgor
further agrees to take such actions as the Pledgee deems reasonably necessary or
desirable to effect the foregoing and to permit the Pledgee to exercise any of
its rights and remedies hereunder, and agrees to provide an opinion of counsel
reasonably satisfactory to the Pledgee with respect to any such pledge of
uncertificated Securities promptly upon request of the Pledgee.

            4. APPOINTMENT OF SUB-AGENTS; ENDORSEMENTS, ETC. (a) The Pledgee
shall have the right to appoint one or more sub-agents for the purpose of
retaining physical possession of the Pledged Securities, which may be held (in
the discretion of the Pledgee) in the name of such Pledgor, endorsed or assigned
in blank or in favor of the Pledgee or any nominee or nominees of the Pledgee or
a sub-agent appointed by the Pledgee. The Pledgee agrees to promptly notify the
relevant Pledgor after the appointment of any sub-agent; provided, however, that
the failure to give such notice shall not affect the validity of such
appointment.

            (b) In the case of any Pledgor's grant to the Pledgee of Securities
of any corporation, partnership or limited liability company that holds a Nevada
gaming license, such Securities shall be held by a sub-agent of the Pledgee
residing in the state of Nevada.

            5. VOTING, ETC., WHILE NO EVENT OF DEFAULT. Unless and until an
Event of Default shall have occurred and be continuing, each Pledgor shall be
entitled to (i) exercise any and all voting and other consensual rights
pertaining to the Pledged Stock and to give all consents, waivers or
ratification's in respect thereof; and (ii) exercise any and all voting,
consent, administration, management and other rights and remedies under (x) any
limited liability company agreement or operating agreement or otherwise with
respect to the Pledged Limited Liability Interests of such Pledgor and (y) any
partnership agreement or otherwise with respect to the Pledged Partnership
Interests of such Pledgor; provided, that no vote shall be cast or any consent,
waiver or ratification given or any action taken which would violate or be
inconsistent with any of the terms of this Agreement or any other Credit
Document, or which would have the effect of impairing the rights, priorities or
remedies of the Pledgee or any other Secured Creditor under this Agreement or
any other Credit Documents. All such rights of such Pledgor to vote and to give
consents, waivers and ratification's shall cease in case an Event of Default
shall occur and be continuing, and Section 7 hereof shall become applicable.

            6. DIVIDENDS AND OTHER DISTRIBUTIONS. Unless an Event of Default
shall have occurred and be continuing, all cash dividends and other cash
distributions payable in respect of the Pledged Securities shall be paid to the
respective Pledgor; provided, that all cash dividends and other cash
distributions payable in respect of any Pledged Security which are determined by
the Pledgee to represent in whole or in part an extraordinary, liquidating or
other distribution in return of capital shall be paid, to the extent so
determined to represent an extraordinary, liquidating or other distribution in
return of capital, to the Pledgee and retained by it as part of the Collateral.
The Pledgee shall also be entitled to receive directly, and to retain as part of
the Collateral:

                  (i) all other or additional stock or other securities or
            property (other than cash)
<PAGE>   11
            paid or distributed by way of dividend or otherwise in respect of
            the Pledged Stock, Pledged Limited Liability Company Interests and
            Pledged Partnership Interests;

                  (ii) all other or additional stock or other securities or
            property (including cash) paid or distributed in respect of the
            Pledged Stock, Pledged Limited Liability Company Interests or
            Pledged Partnership Interests by way of stock-split, spin-off,
            split-up, reclassification, combination of shares or similar
            rearrangement; and

                  (iii) all other or additional stock or other securities or
            property (including cash) which may be paid in respect of the
            Collateral by reason of any consolidation, merger, exchange of
            stock, conveyance of assets, liquidation or similar corporate
            reorganization.

Nothing contained in this Section 6 shall limit or restrict in any way the
Pledgee's right to receive proceeds of the Collateral in any form in accordance
with Section 3 of this Agreement. All dividends, distributions or other payments
which are received by the Pledgor contrary to the provisions of this Section 6
and Section 7 below shall be received in trust for the benefit of the Pledgee,
shall be segregated from other property or funds of the Pledgor and shall be
forthwith paid over to the Pledgee as Collateral in the same form as so received
(with any necessary endorsement).

                  7. REMEDIES IN CASE OF EVENT OF DEFAULT. In case an Event of
Default shall have occurred and be continuing, the Pledgee shall be entitled to
exercise all of the rights, powers and remedies (whether vested in it by this
Agreement or by any other Credit Document or, to the extent then in effect and
secured hereby, any Interest Rate Protection Agreement, any ITT Note Document,
any Permitted Refinancing Document, any Senior Secured Note Document (with all
of the Documents listed above being herein collectively called the "Senior
Documents" or the "Secured Debt Agreements") or by law) for the protection and
enforcement of its rights in respect of the Collateral, and the Pledgee shall be
entitled to exercise all the rights and remedies of a secured party under the
UCC and also shall be entitled, without limitation, to exercise the following
rights, which each Pledgor hereby agrees to be commercially reasonable:

                  (i) to receive all amounts payable in respect of the
            Collateral payable to such Pledgor under Section 6 hereof;

                  (ii) to transfer all or any part of the Pledged Securities
            into the Pledgee's name or the name of its nominee or nominees (the
            Pledgee agrees to promptly notify the relevant Pledgor after such
            transfer; provided, however, that the failure to give such notice
            shall not affect the validity of such transfer);

                  (iii) to vote all or any part of the Pledged Stock, Pledged
            Limited Liability Company Interests or Pledged Partnership Interests
            (whether or not transferred into the name of the Pledgee) and give
            all consents, waivers and ratification's in respect of the
            Collateral and otherwise act with respect thereto as though it were
            the outright owner thereof (each Pledgor hereby irrevocably
            constituting and appointing the Pledgee the proxy and
            attorney-in-fact of such Pledgor, with full power of substitution to
            do so); and
<PAGE>   12
                  (iv) at any time or from time to time to sell, assign and
            deliver, or grant options to purchase, all or any part of the
            Collateral, or any interest therein, at any public or private sale,
            without demand of performance, advertisement or notice of intention
            to sell or of the time or place of sale or adjournment thereof or to
            redeem or otherwise (all of which are hereby waived by each
            Pledgor), for cash, on credit or for other property, for immediate
            or future delivery without any assumption of credit risk, and for
            such price or prices and on such terms as the Pledgee in its
            absolute discretion may determine; provided, that at least 10
            Business Days' notice of the time and place of any such sale shall
            be given to such Pledgor. Each Pledgor hereby waives and releases to
            the fullest extent permitted by law any right or equity of
            redemption with respect to the Collateral, whether before or after
            sale hereunder, and all rights, if any, of marshalling the
            Collateral and any other security for the Obligations or otherwise.
            At any such sale, unless prohibited by applicable law, the Pledgee
            on behalf of the Secured Creditors may bid for and purchase all or
            any part of the Collateral so sold free from any such right or
            equity of redemption. Neither the Pledgee nor any Secured Creditor
            shall be liable for failure to collect or realize upon any or all of
            the Collateral or for any delay in so doing nor shall any of them be
            under any obligation to take any action whatsoever with regard
            thereto.

                  8. REMEDIES, ETC., CUMULATIVE. Each right, power and remedy of
the Pledgee provided for in this Agreement or any other Secured Debt Agreement
or now or hereafter existing at law or in equity or by statute shall be
cumulative and concurrent and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by the Pledgee or any
other Secured Creditor of any one or more of the rights, powers or remedies
provided for in this Agreement or any other Secured Debt Agreement or now or
hereafter existing at law or in equity or by statute or otherwise shall not
preclude the simultaneous or later exercise by the Pledgee or any other Secured
Creditor of all such other rights, powers or remedies, and no failure or delay
on the part of the Pledgee or any other Secured Creditor to exercise any such
right, power or remedy shall operate as a waiver thereof. The Secured Creditors
agree that this Agreement may be enforced only by the action of the
Administrative Agents or the Pledgee, in each case acting upon the instructions
of the Required Secured Creditors (as defined in Annex G hereto) and that no
other Secured Creditor shall have any right individually to seek to enforce or
to enforce this Agreement or to realize upon the security to be granted hereby,
it being understood and agreed that such rights and remedies may be exercised by
the Administrative Agents or the Pledgee, as the case may be, for the benefit of
the Secured Creditors upon the terms of this Agreement.

                  9. APPLICATION OF PROCEEDS. (a) All moneys collected by the
Collateral Agent upon any sale or other disposition of the Collateral of each
Pledgor, together with all other moneys received by the Collateral Agent
hereunder, shall be applied as follows:

                  (i) first, to the payment of all Obligations owing to the
            Collateral Agent of the type provided in clauses (vii) and (viii) of
            the definition of Obligation;

                  (ii) second, to the extent proceeds remain after the
            application pursuant to the preceding clause (i), an amount equal to
            the outstanding Primary Obligations of the respective Pledgor shall
            be paid to the Secured Creditors (with such Secured Creditors
<PAGE>   13
            being herein called the "Senior Secured Creditors") as provided in
            Section 9(e) hereof, with each Senior Secured Creditor receiving an
            amount equal to its outstanding Primary Obligations of such Pledgor
            or, if the proceeds are insufficient to pay in full all such Primary
            Obligations, its Pro Rata Share of the amount remaining to be
            distributed;

                  (iii) third, to the extent proceeds remain after the
            application pursuant to the preceding clauses (i) and (ii), an
            amount equal to the outstanding Secondary Obligations of the
            respective Pledgor shall be paid to the Senior Secured Creditors as
            provided in Section 9(e) hereof, with each Senior Secured Creditor
            receiving an amount equal to its outstanding Secondary Obligations
            of such Pledgor or, if the proceeds are insufficient to pay in full
            all such Secondary Obligations, its Pro Rata Share of the amount
            remaining to be distributed; and

                  (iv) fifth, to the extent proceeds remain after the
            application pursuant to the preceding clauses (i) through (iii),
            inclusive, and following the termination of this Agreement pursuant
            to Section 18 hereof, to the relevant Pledgor or to whomever may be
            lawfully entitled to receive such surplus.

                  (b) For purposes of this Agreement (x) "Pro Rata Share" shall
mean, when calculating a Secured Creditor's portion of any distribution or
amount, that amount (expressed as a percentage) equal to a fraction the
numerator of which is the then unpaid amount of such Secured Creditor's Primary
Obligations or Secondary Obligations, as the case may be, of the respective
Pledgor and the denominator of which is the then outstanding amount of all
Primary Obligations or Secondary Obligations, as the case may be, of the
respective Pledgor, (y) "Primary Obligations" of any Pledgor shall mean (i) in
the case of the Credit Document Obligations, all Obligations of such Pledgor
arising out of or in connection with (including, without limitation, as obligor
or guarantor, as the case may be) the principal of, and interest on, all Loans,
all Unpaid Drawings theretofore made (together with all interest accrued
thereon), and the aggregate Stated Amounts of all Letters of Credit issued under
the Credit Agreement, and all regularly accruing Fees, (ii) in the case of the
ITT Note Obligations, all Obligations of such Pledgor secured hereby arising out
of or in connection with (including, without limitation, as obligor or
guarantor, as the case may be) the principal of, and interest on, the ITT Notes,
(iii) in the case of Qualified Permitted Refinancing Obligations, all
Obligations of such Pledgor secured hereby arising out of or in connection with
(including, without limitation, as obligor or guarantor, as the case may be) the
principal of, and interest on, the Qualified Permitted Refinancing Indebtedness,
(iv) in the case of the Senior Secured Note Obligations, all Obligations of such
Pledgor secured hereby arising out of or in connection with (including, without
limitation, as obligor or guarantor, as the case may be) the principal of, and
interest on, the Senior Secured Notes and (v) in the case of the Interest Rate
Protection Obligations, all Obligations of such Pledgor arising out of or in
connection with (including, without limitation, as a direct obligor or a
guarantor, as the case may be) Interest Rate Protection Agreements (other than
indemnities, fees (including, without limitation, attorneys' fees) and similar
obligations and liabilities), and (z) "Secondary Obligations" of any Pledgor
shall mean all Obligations of such Pledgor secured hereby other than Primary
Obligations.

                  (c) When payments to Senior Secured Creditors are based upon
their respective
<PAGE>   14
Pro Rata Shares, the amounts received by such Senior Secured Creditors hereunder
shall be applied (for purposes of making determinations under this Section 9
only) (i) first, to the Primary Obligations of the respective Pledgor and (ii)
second, to the Secondary Obligations of the respective Pledgor.

                  (d) Each of the Secured Creditors agrees and acknowledges that
if the Lender Creditors are to receive a distribution on account of undrawn
amounts with respect to Letters of Credit issued under the Credit Agreement,
such amounts shall be paid to the Paying Agent under the Credit Agreement and
held by it, for the equal and ratable benefit of the Lender Creditors as such.
If any amounts are held as cash security pursuant to the immediately preceding
sentence, then upon the termination of all outstanding Letters of Credit, and
after the application of all such cash security to the repayment of all
Obligations owing to the Lender Creditors after giving effect to the termination
of all such Letters of Credit, if there remains any excess cash, such excess
cash shall be returned by the Paying Agent to the Collateral Agent for
distribution in accordance with Section 9(a) hereof.

                  (e) Except as set forth in Section 9(d) hereof, all payments
required to be made hereunder shall be made (i) if to the Lender Creditors, to
the Paying Agent under the Credit Agreement for the account of the Lender
Creditors, and (ii) if to any other Secured Creditors (other than the Collateral
Agent), to the trustee, paying agent or other similar representative (each a
"Representative") for such Secured Creditors or, in the absence of such a
Representative, directly to the other Secured Creditors.

                  (f) For purposes of applying payments received in accordance
with this Section 9, the Collateral Agent shall be entitled to rely upon (i) the
Paying Agent under the Credit Agreement and (ii) the Representative for any
other Secured Creditors or, in the absence of such a Representative, upon the
respective Secured Creditors for a determination (which the Paying Agent, each
Representative for any other Secured Creditors and the Secured Creditors agree
(or shall agree) to provide upon request of the Collateral Agent) of the
outstanding Primary Obligations and Secondary Obligations owed to the Secured
Creditors. Unless it has actual knowledge (including by way of written notice
from a Representative for any Secured Creditor or directly from a Secured
Creditor) to the contrary, the Collateral Agent, in acting hereunder, shall be
entitled to assume that no Interest Rate Protection Agreements are in existence.

                  (g) It is understood and agreed that each Pledgor shall remain
liable to the extent of any deficiency between the amount of the proceeds of the
Collateral pledged by it hereunder and the aggregate amount of the Obligations
of such Pledgor.

                  10. PURCHASERS OF COLLATERAL. Upon any sale of the Collateral
by the Pledgee hereunder (whether by virtue of the power of sale herein granted,
pursuant to judicial process or otherwise), the receipt of the Pledgee or the
officer making the sale shall be a sufficient discharge to the purchaser or
purchasers of the Collateral so sold, and such purchaser or purchasers shall not
be obligated to see to the application of any part of the purchase money paid
over to the Pledgee or such officer or be answerable in any way for the
misapplication or nonapplication thereof.
<PAGE>   15
                  11. INDEMNITY. Each Pledgor jointly and severally agrees (i)
to indemnify and hold harmless the Pledgee in such capacity and each other
Secured Creditor from and against any and all claims, demands, losses, judgments
and liabilities of whatsoever kind or nature, and (ii) to reimburse the Pledgee
and each other Secured Creditor for all reasonable costs and expenses, including
reasonable attorneys' fees, in each case to the extent growing out of or
resulting from the exercise by the Pledgee of any right or remedy granted to it
hereunder or under any other Secured Debt Agreement except, with respect to
clauses (i) and (ii) above, to the extent arising from the Pledgee's or such
other Secured Creditor's gross negligence or willful misconduct. In no event
shall the Pledgee be liable, in the absence of gross negligence or willful
misconduct on its part, for any matter or thing in connection with this
Agreement other than to account for moneys actually received by it in accordance
with the terms hereof. If and to the extent that the obligations of the Pledgors
under this Section 11 are unenforceable for any reason, each Pledgor hereby
agrees to make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.

                  12. FURTHER ASSURANCES; POWER OF ATTORNEY. (a) Each Pledgor
agrees that it will join with the Pledgee in executing and, at such Pledgor's
own expense, file and refile under the applicable UCC or such other law such
financing statements, continuation statements and other documents in such
offices as the Pledgee may reasonably deem necessary or appropriate and wherever
required or permitted by law in order to perfect and preserve the Pledgee's
security interest in the Collateral and hereby authorizes the Pledgee to file
financing statements and amendments thereto relative to all or any part of the
Collateral without the signature of such Pledgor where permitted by law, and
agrees to do such further acts and things and to execute and deliver to the
Pledgee such additional conveyances, assignments, agreements and instruments as
the Pledgee may reasonably deem necessary or advisable to carry into effect the
purposes of this Agreement or to further assure and confirm unto the Pledgee its
rights, powers and remedies hereunder.

                  (b) Each Pledgor hereby appoints the Pledgee such Pledgor's
attorney-in-fact, with full authority in the place and stead of such Pledgor and
in the name of such Pledgor or otherwise, to act from time to time after the
occurrence and during the continuance of an Event of Default in the Pledgee's
reasonable discretion to take any action and to execute any instrument which the
Pledgee may deem necessary or advisable to accomplish the purposes of this
Agreement.

                  13. THE PLEDGEE AS AGENT. The Pledgee will hold in accordance
with this Agreement all items of the Collateral at any time received under this
Agreement. It is expressly understood and agreed that the obligations of the
Pledgee as holder of the Collateral and interests therein and with respect to
the disposition thereof, and otherwise under this Agreement, are only those
expressly set forth in this Agreement. The Pledgee shall act hereunder on the
terms and conditions set forth in Annex G hereto, the terms of which shall be
deemed incorporated herein by reference as fully as if same were set forth
herein in their entirety.

                  14. TRANSFER BY PLEDGORS. No Pledgor will sell or otherwise
dispose of, grant any option with respect to, or mortgage, pledge or otherwise
encumber any of the Collateral or any interest therein (except in accordance

by the terms of the Credit Agreement).

                  15. REPRESENTATIONS, WARRANTIES AND COVENANTS OF PLEDGORS. (a)
Each Pledgor represents, warrants and covenants that:

                  (i) it is the legal, record and beneficial owner of, and has

            be limited by applicable bankruptcy, insolvency, reorganization,

            generally and by equitable principles (regardless of whether
            enforcement is sought in equity or at law);

                  (iv) no consent of any other party (including, without

            the Pledgee of certain of its remedies hereunder or which may be
            required to be obtained by the Pledgee pursuant to Section 22 or 23
            hereof in connection with the exercise of its rights and remedies
            hereunder;

            party or which purports to be binding upon such Pledgor or any of
            its Subsidiaries or upon any of their respective assets and will not
            result in the creation or imposition (or the obligation to create or
            impose) of any lien or encumbrance on any of the assets of such
            Pledgor or any of its Subsidiaries except as contemplated by this
            Agreement;

            Pledgor which would include the Securities;

                  (viii) each Pledged Partnership Interest has been validly
            acquired and is fully paid for (to the extent applicable) and is
            duly and validly pledged hereunder;

                  (ix) each partnership agreement is the legal, valid and
            binding obligation of the applicable Pledgor, enforceable in
            accordance with its terms;

                  (x) no Pledgor is in default in the payment of any portion of
            any mandatory capital contribution, if any, required to be made
            under any general or limited partnership agreement to which such
            Pledgor is a party, and no Pledgor is in violation of any other
            material provisions of any partnership agreement to which such
            Pledgor is a party, or otherwise in default or violation
            thereunder;

                  (xi) no Pledged Partnership Interest is subject to any
            defense, offset or counterclaim, nor have any of the foregoing been
            asserted or alleged against such Pledgor by any Person with respect
            thereto;

                  (xii) the pledge and assignment of the Pledged Partnership
            Interests and/or Pledged Limited Liability Company Interests
            pursuant to this Agreement, together with the relevant filings or
            recordings under the UCC (which filings and recordings have been or
            will be made), create a valid perfected and continuing first
            priority security interest in such Partnership Interests and/or
            Limited Liability Company Interests and the proceeds thereof,
            subject to no prior lien or encumbrance or to any agreement
            purporting to grant to any third party a lien or encumbrance on the
            property or assets of such Pledgee or which would include the
            collateral;

                  (xiii) there are no currently effective financing statements
            in respect of the UCC covering property which is now or hereafter
            may be included in the Collateral and such Pledgor will not, without
            the prior written consent of the Pledgee, execute and, until the
            Termination Date (as hereinafter defined), there will not ever be on
            file in any public office any enforceable financing statement or
            statements covering any or all of the Collateral, except financing
            statements filed or to be filed in favor of the Pledgee as secured
            party;

                  (xiv) each Pledgor shall give the Pledgee prompt notice of any
            written claim it receives relating to the Collateral; and

                  (xv) each Pledgor shall deliver to the Pledgee a copy of each
            other demand, notice
<PAGE>   18
            or document received by it which may adversely affect the Pledgee's
            interest in the Collateral promptly upon, but in any event within 10
            days after, such Pledgor's receipt thereof.

                  Each Pledgor covenants and agrees that it will defend the
Pledgee's right, title and security interest in and to the Securities and the
proceeds thereof against the claims and demands of all persons whomsoever; and
such Pledgor covenants and agrees that it will have like title to and right to
pledge any other property at any time hereafter pledged to the Pledgee as
Collateral hereunder and will likewise defend the right thereto and security
interest therein of the Pledgee and the other Secured Creditors.

                  (b) Each Pledgor hereby further represents, warrants and
covenants that as of the date hereof, the chief executive office of such Pledgor
is located at the address indicated on Annex F hereto for such Pledgor. Such
Pledgor will not move its chief executive office except to such new location as
such Pledgor may establish in accordance with the last sentence of this Section
15(b). No Pledgor shall establish new locations for such offices until (i) it
shall have given to the Pledgee not less than 30 days' prior written notice of
its intention to do so, clearly describing such new location and providing such
other information in connection therewith as the Pledgee may reasonably request,
(ii) it shall have delivered to the Pledgee a written supplement to Annex F
hereto in the form of Exhibit A-1 hereto as provided in clause (c) below showing
the new location of its chief executive office and (iii) with respect to such
new location, it shall have taken all action, reasonably satisfactory to the
Pledgee, to maintain all security interest of the Pledgee in the Collateral
intended to be granted hereby at all times fully perfected and in full force and
effect.

                  (c) Without in any way limiting Section 3.2 hereof, at any
time and from time to time that any Pledgor (x) determines that the information
with respect to it contained on Annex A, B, C and/or F, as the case may be, is
inaccurate or (y) acquires any additional Securities which have not already been
pledged hereunder and reflected on Annexes A through C, as appropriate, such
Pledgor shall deliver a supplement to this Agreement, substantially in the form
of Exhibit A-1 hereto (each a "Pledge and Security Agreement Supplement") adding
(or, in the case of any Securities released pursuant to Section 18(b) hereof,
deleting) such Securities to (from) Annexes A through C hereto, as appropriate.
The execution and delivery of any such supplement shall not require the consent
of any Pledgor hereunder. It is understood and agreed that the pledge and
security interests granted hereunder shall apply to all Collateral as provided
in Section 3.1 regardless of the failure of any Pledgor to deliver, or any
inaccurate information stated in, the Pledge and Security Agreement Supplement
as otherwise provided above.

                  (d) Each Pledgor hereby covenants and agrees that with respect
to all Partnership Interests or Limited Liability Company Interests, in each
case required to be pledged by it hereunder, such Pledgor will deliver to the
respective Pledged Partnerships or Pledged Limited Liability Companies, as the
case may be (with copies to the Collateral Agent) a notice (appropriately
completed) in the form of Annex D attached hereto and by this reference made a
part hereof (each such notice a "Partnership/LLC Notice") and such Pledgor will
use its reasonable best efforts to cause to be delivered to the Collateral Agent
an acknowledgment in the form set forth as Annex E attached hereto (each such
acknowledgment, a "Pledge
<PAGE>   19
Acknowledgment"), duly executed by the relevant Pledged Partnership and/or
Pledged Limited Liability Company, as the case may be, in each case within
forty-five days following the date of any pledge of any Pledged Partnership
Interests or Pledged Limited Liability Company Interests hereunder.

                  16. PLEDGORS' OBLIGATIONS ABSOLUTE, ETC. The obligations of
each Pledgor under this Agreement shall be absolute and unconditional and shall
remain in full force and effect without regard to, and shall not be released,
suspended, discharged, terminated or otherwise affected by, any circumstance or
occurrence whatsoever, including, without limitation: (i) any renewal,
extension, amendment or modification of or addition or supplement to or deletion
from any Secured Debt Agreement or any other instrument or agreement referred to
therein, or any assignment or transfer of any thereof; (ii) any waiver, consent,
extension, indulgence or other action or inaction under or in respect of any
such agreement or instrument or this Agreement; (iii) any furnishing of any
additional security to the Pledgee or its assignee or any acceptance thereof or
any release of any security by the Pledgee or its assignee; (iv) any limitation
on any party's liability or obligations under any such instrument or agreement
or any invalidity or unenforceability, in whole or in part, of any such
instrument or agreement or any term thereof; (v) any limitation on any other
Pledgor's liability or obligations under this Agreement, the Guaranty or any
other Credit Document or any invalidity or unenforceability, in whole or in
part, of this Agreement, the Guaranty or any other Credit Document or any term
thereof; or (vi) any bankruptcy, insolvency, reorganization, composition,
adjustment, dissolution, liquidation or other like proceeding relating to such
Pledgor or any Subsidiary of such Pledgor, or any action taken with respect to
this Agreement by any trustee or receiver, or by any court, in any such
proceeding, whether or not such Pledgor shall have notice or knowledge of any of
the foregoing.

                  17. REGISTRATION, ETC. (a) If an Event of Default shall have
occurred and be continuing and any Pledgor shall have received from the Pledgee
a written request or requests that such Pledgor cause any registration,
qualification or compliance under any Federal or state securities law or laws to
be effected with respect to all or any part of the Pledged Securities, such
Pledgor as soon as practicable and at its expense will use its best efforts to
cause such registration to be effected (and be kept effective) and will use its
best efforts to cause such qualification and compliance to be effected (and be
kept effective) as may be so requested and as would permit or facilitate the
sale and distribution of such Pledged Securities, including, without limitation,
registration under the Securities Act as then in effect (or any similar statute
then in effect), appropriate qualifications under applicable blue sky or other
state securities laws and appropriate compliance with any other government
requirements; provided, that the Pledgee shall furnish to such Pledgor such
information regarding the Pledgee as such Pledgor may request in writing and as
shall be required in connection with any such registration, qualification or
compliance. Such Pledgor will cause the Pledgee to be kept reasonably advised in
writing as to the progress of each such registration, qualification or
compliance and as to the completion thereof, will furnish to the Pledgee such
number of prospectuses, offering circulars or other documents incident thereto
as the Pledgee from time to time may reasonably request, and will indemnify the
Pledgee, each other Secured Creditor and all others participating in the
distribution of the Pledged Securities against all claims, losses, damages and
liabilities caused by any untrue statement (or alleged untrue statement) of a
material fact contained therein (or in any related
<PAGE>   20
registration statement, notification or the like) or by any omission (or alleged
omission) to state therein (or in any related registration statement,
notification or the like) a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the
same may have been caused by an untrue statement or omission based upon
information furnished in writing to such Pledgor by the Pledgee or such other
Secured Creditor expressly for use therein.

                  (b) If at any time when the Pledgee shall determine to
exercise its right to sell all or any part of the Pledged Securities pursuant to
Section 6 hereof, such Pledged Securities or the part thereof to be sold shall
not, for any reason whatsoever, be effectively registered under the Securities
Act, as then in effect, the Pledgee may, in its sole and absolute discretion,
sell such Pledged Securities or part thereof by private sale in such manner and
under such circumstances as the Pledgee may deem necessary or advisable in order
that such sale may legally be effected without such registration; provided, that
at least 10 Business Days' notice of the time and place of any such sale shall
be given to such Pledgor. Without limiting the generality of the foregoing, in
any such event the Pledgee, in its sole and absolute discretion: (i) may proceed
to make such private sale notwithstanding that a registration statement for the
purpose of registering such Pledged Securities or part thereof shall have been
filed under such Securities Act; (ii) may approach and negotiate with a single
possible purchaser to effect such sale; and (iii) may restrict such sale to a
purchaser who will represent and agree that such purchaser is purchasing for its
own account, for investment, and not with a view to the distribution or sale of
such Pledged Securities or part thereof. In the event of any such sale, the
Pledgee shall incur no responsibility or liability for selling all or any part
of the Pledged Securities at a price which the Pledgee, in its sole and absolute
discretion, may in good faith deem reasonable under the circumstances,
notwithstanding the possibility that a substantially higher price might be
realized if the sale were deferred until after registration as aforesaid.

                  18. TERMINATION, RELEASE. (a) After the Termination Date (as
defined below), this Agreement shall terminate (provided that all indemnities
set forth herein including, without limitation, in Section 11 hereof shall
survive any such termination) and the Pledgee, at the request and expense of the
respective Pledgor, will promptly execute and deliver to such Pledgor a proper
instrument or instruments acknowledging the satisfaction and termination of this
Agreement, and will duly assign, transfer and deliver to such Pledgor (without
recourse and without any representation or warranty) such of the Collateral as
may be in the possession of the Pledgee and as has not theretofore been sold or
otherwise applied or released pursuant to this Agreement. As used in this
Agreement, "Termination Date" shall mean the date upon which the Total
Commitments and all Interest Rate Protection Agreements have been terminated, no
Note or Letter of Credit is outstanding and all other Obligations (excluding
normal continuing indemnity obligations which survive in accordance with their
terms, so long as no amounts are then due and payable in respect thereof) have
been indefeasibly paid in full.

                  (b) So long as no ITT Note Event (as defined below) has
occurred and is continuing, in the event that any part of the Collateral is sold
(but not to any Borrower or a Subsidiary thereof) in connection with a sale
permitted by Section 9.02 of the Credit Agreement or is otherwise released at
the direction of the Required Secured Creditors), the Pledgee, at the request
and expense of such Pledgor will duly assign, transfer and deliver to such
Pledgor
<PAGE>   21
(without recourse and without any representation or warranty) such of the
Collateral as is then being (or has been) so sold or released and as may be in
possession of the Pledgee and has not theretofore been released pursuant to this
Agreement. Any proceeds of Collateral sold as contemplated by the immediately
preceding sentence may be applied in accordance with the requirements of the
Credit Agreement. As used herein, an "ITT Note Event" shall mean the
acceleration of the maturity of any ITT Notes or the failure to pay at maturity
any ITT Notes, or the occurrence of any default or event of default of the types
specified in Section 6.1(f) or (g) of the ITT Indenture; provided that no ITT
Note Event shall be deemed to exist (x) at any time when no ITT Note Obligations
are secured hereunder or (y) after all ITT Note Obligations have been repaid in
full.

                  (c) At any time that a Pledgor desires that Collateral be
released as provided in the foregoing Section 18(a) or (b), it shall deliver to
the Pledgee a certificate signed by an Authorized Officer of such Pledgor
stating that the release of the respective Collateral is permitted pursuant to
Section 18(a) or (b), and the Pledgee shall be entitled (but not required) to
conclusively rely thereon.

                  19. NOTICES, ETC. Except as otherwise specified herein, all
notices, requests, demands or other communications to or upon the respective
parties hereto shall be deemed to have been given or made when delivered to the

or permitted to be given or made under this Agreement, addressed as follows:

            specified in writing to each Pledgor and the Pledgee;

or at such other address as shall have been furnished in writing by any Person
described above to the party required to give notice hereunder.

                  20. WAIVER; AMENDMENT. None of the terms and conditions of
this Agreement may be changed, waived, modified or varied in any manner
whatsoever unless in writing duly signed by each Pledgor directly affected
thereby (it being understood that additional Pledgors may be added as parties
hereto from time to time in accordance with Section 24 and Pledgors may be
released as parties hereto in accordance with Section 21, and that no consent of
any other Pledgor or of the Secured Creditors shall be required in connection
therewith) and the Pledgee (with the written consent of either (x) the Required
Lenders (or all the Lenders if required by Section 13.12 of the Credit
Agreement) at all times prior to the time at which all Credit Document
Obligations have been paid in full and all commitments pursuant to the Credit
Agreement have terminated (with such date being herein called the "Credit
Document Obligations Termination Date") or (y) the holders of at least a
majority of the then outstanding Obligations secured hereby at all times after
the Credit Document Obligations Termination Date provided, that any change,
waiver, modification or variance affecting the rights and benefits of a single
Class (as defined below), with outstanding Obligations of the respective Class
secured hereby at such time, of Secured Creditors (and not all Secured Creditors
in a like or similar manner) shall require the written consent of the Requisite
Creditors (as defined below) of such Class. Notwithstanding anything to the
contrary contained above, it is understood and agreed that the Required Lenders
may agree to modifications to this Agreement for the purpose, among other
things, of securing additional extensions of credit (including, without
limitation, pursuant to the Credit Agreement or any refinancing or extension
thereof), with such changes not being subject to the proviso to the immediately
preceding sentence. Furthermore, the proviso to the second preceding sentence
shall not apply to any release of collateral effected in accordance with the
requirements of Section 18 of this Agreement, or any other release of collateral
or termination of this Agreement so long as the Parent Companies certify that
such actions will not violate the terms of any Secured Debt Agreement then in
effect. For the purpose of this Agreement, the term "Class" shall mean each
class of Secured Creditors with outstanding Obligations secured hereby at such
time, i.e., whether (i) the Lender Creditors as holders of the Credit Document
Obligations, (ii) the ITT Noteholders as holders of ITT Note Obligations secured
hereby, (iii) the Permitted Refinancing Creditors as holders of Permitted
Refinancing Obligations secured hereby, (iv) the Senior Secured Noteholders as
the holders of Senior Secured Note Obligations secured hereby and (v) the
Interest Rate Protection Creditors as holders of the Interest Rate Protection
Obligations. For the purpose of this Agreement, the term "Requisite Creditors"
of any Class shall mean each of (i) with respect to the Credit Document
Obligations, the Required Lenders and (ii) with respect to any other
Obligations, the holders of at least a majority of all obligations outstanding
from time to time under the respective Secured Debt Agreement.

                  21. RELEASE OF GUARANTORS. In the event any Pledgor which is a
Subsidiary of any Borrower party to the Guaranty is released from the Guaranty,
such Pledgor (so long as not a Borrower) shall be released from this Agreement
and this Agreement shall, as to
<PAGE>   23
such Pledgor only, have no further force or effect.

                  22. GAMING APPROVALS. (a) Unless approved in advance by the
Nevada Gaming Commission (the "NGC"), the Pledged Securities issued by ITT
Corporation, a Nevada corporation ("ITT"), and ITT Sheraton Corporation, a
Nevada Corporation ("ITTSC"), shall not be subject to the pledge under this
Pledge Agreement, and the grant of any security interest shall not be effective
for any purpose as to any Pledged Securities issued by ITT or ITTSC, nor shall
any interest in any Pledged Securities issued by ITT or ITTSC be transferred in
any manner whatsoever to the Pledgee or any other Person.

                  (b) No Pledged Securities issued by ITT or ITTSC shall be
otherwise sold, assigned, transferred, pledged or otherwise disposed of, whether
pursuant to the Pledge Agreement or the exercise of any right, power or remedy
provided for therein or otherwise, unless the grant of the security interest or
such other disposition as the case may be, has been approved in advance by the
NGC, and unless the transferee of the Pledged Securities issued by ITT and ITTSC
disposed of shall have first obtained any and all licenses, findings of
suitability or approvals required by the Nevada Gaming Control Act and the
regulations thereunder, or shall have been found to be individually qualified to
be licensed, as appropriate. Without limiting the generality of foregoing,
approval of the Pledge Agreement by the NGC shall not constitute permission to
foreclose on the same or make any other disposition of the Pledged Securities
issued by ITT or ITTSC without a further order of the NGC.

                  (c) Unless the Pledgee or any other Person required to do so,
has obtained any and all licenses, findings of suitability or approvals required
by the Nevada Gaming Control Act and the regulations thereunder, such Pledgee or
other Person shall not receive any dividend, payment or other distribution from
or exercise any right in respect to, any Pledged Securities issued by ITT or
ITTSC.

                  (d) Unless approved in advance by the NGC, no restriction on
the transfer of any Pledged Securities issued by ITT or ITTSC, or any covenant
or agreement not to encumber any Pledged Securities issued by ITT or ITTSC,
shall be effective for any purpose whatsoever.

                  (e) If at any time after the Pledgee or any other Person
becomes the owner of any Pledged Securities issued by ITT or ITTSC, whether
pursuant to the Pledge Agreement or the exercise of any right, power or remedy
provided for therein or otherwise, the NGC finds that such Pledgee or other
Person is unsuitable to continue as a gaming licensee or otherwise to be
associated with a gaming licensee in the state of Nevada (hereinafter referred
to as an "Unsuitable Person"), such Unsuitable Person shall immediately offer
any and all Pledged Securities of ITT and ITTSC owned by such Unsuitable Person
to ITT or ITTSC, respectively, for purchase and shall allow ITT and ITTSC,
respectively, to purchase such Pledged Securities for cash at fair market value
thereof, as determined by the NGC, within ten (10) days after the date of the
offer or upon such other terms and conditions for such acquisition of such
Pledged Securities as may be prescribed by the NGC.

                  (f) The Pledgee and any such other Person hereby acknowledge,
understand and agree and each other person that concurrently with the execution
and delivery of the Pledge
<PAGE>   24
Agreement or at any time thereafter, acquires any right, title or interest in
any Pledged Securities of ITT or ITTSC, pursuant to the Pledge Agreement or the
exercise of any right, power or remedy provided for therein by virtue of such
acquisition of the Pledged Securities, shall be deemed to have acknowledged.
understood and agreed that:

                  (i) Beginning upon the date on which the NGC serves upon ITT
            or ITTSC, respectively, notice of the determination of unsuitability
            pursuant to Section 2 of Nevada Revised Statutes ("NRS") 463.510, it
            will be unlawful for the Unsuitable Person owning any Pledged
            Securities issued by ITT or ITTSC:

                        (A) To receive any dividend or interest upon any such
                            securities;

                        (B) To exercise, directly or through any Pledgee or
                            nominee, any voting right conferred by such
                            security;

                        (C) To receive any remuneration in any form from ITT or
                            ITTSC, for services rendered or otherwise; or,

                        (D) To receive any other payment or distribution, of
                            any kind whatsoever, in respect of any such
                            security, by way of or pursuant to payment of
                            principal, redemption, conversion, exchange or
                            liquidation or any other transaction.

                  (ii) Each certificate evidencing one or more of the Pledged
            Securities issued by ITT or ITTSC shall bear a statement on both
            sides of the certificate of the restrictions described in subsection
            (f) (i) above, to the extent required by Nevada law or any order of
            the NGC.

                  (iii) The physical location of each certificate evidencing one
            or more of the Pledged Securities issued by ITT or ITTSC shall at
            all times remain within the territory of the state of Nevada, and
            each of such certificates shall be made available for inspection by
            agents of the NGC or the Nevada State Gaming Control Board ("SGCB"),
            immediately upon request during normal business hours. Except as
            permitted by the NGC for the purpose of perfecting the Pledge
            Agreement, the holder of any such certificate shall not surrender or
            transfer possession of the same without the prior approval of the
            NGC. The person located within the territory of the state of Nevada
            designated to hold the Pledged Securities on behalf of the Pledgee
            for the purpose of perfecting the Pledge Agreement is FIRST SECURITY
            TRUST COMPANY OF NEVADA.

                  (g) No covenant or provision in the Pledge Agreement shall
preclude ITT or ITTSC from satisfying any financial obligation or requirement
imposed by the Nevada Gaming Control Act or regulations thereunder, including
but not limited to minimum casino bankroll requirements, mandatory game security
reserves, redemption of casino chips and tokens, or payment of winning wagers to
gaming patrons.

                  (h) The Pledgee and any other Person who becomes the owner of
any Pledged

Securities issued by ITT or ITTSC, each severally agree to cooperate with the
NGC and the SGCB in connection with the administration of their regulatory
jurisdiction over ITT, ITTSC and their affiliated companies, including the
provision of such documents or other information as may be reasonably requested
by the NGC or SGCB relating to ITT, ITTSC or any of their affiliated companies
or to the Pledge Agreement.

                  (i) The Pledgee or any other Person who becomes the owner of
any Pledged Securities issued by ITT or ITTSC, each severally agree to comply
with any order or directive of the NGC or SGCB requiring such person or persons
to submit an application for any license, finding of suitability or other
approval pursuant to the Nevada Gaming Control Act and the regulations
thereunder.

                  (j) The provisions of this Section 22 of this Pledge Agreement
shall not modify or restrict the rights and remedies of the Pledgee or any other
Person under the Pledge Agreement in any other pledged collateral except for the
Pledged Securities of ITT or ITTSC; provided, the Pledgee and other Persons
acknowledge, understand and agree that the Nevada Gaming Control Act and the
regulations thereunder impose certain licensing or transaction approval
requirements prior to the exercise of such rights and remedies under the Pledge
Agreement with the respect to the Pledged Securities and other pledged
collateral subject to the Nevada Gaming Control Act and the regulations
thereunder.

                  (k) Notwithstanding any provision contained in this Pledge
Agreement to the contrary, if the granting of a security interest in the capital
stock of any Subsidiary shall conflict with or violate any Gaming Laws, the
Pledgee agrees to (i) release such capital stock from the pledge of this Pledge
Agreement to the extent necessary to avoid such conflict or violation or, (ii)
take any other action, including filing for applicable Approvals, sufficient to
avoid such conflict or violation. The Pledgee further acknowledges and agrees
that, prior to exercising any remedies set forth in the Pledge Agreement with
respect to the Pledged Securities of ITT or ITTSC subject to or affected by any
Gaming Laws, the Pledgee shall obtain any and all Approvals as may be required
by applicable Gaming Laws.

                  23. ACTIONS REQUIRING FCC APPROVAL. (a) Notwithstanding
anything to the contrary contained in this Agreement, or any of the documents
executed pursuant hereto, the Pledgee will not take any action pursuant to this
Agreement, or any such documents, which would constitute or result in any
assignment of any FCC license or any transfer of control of the holder of any
FCC license if such assignment of such license or such transfer of control would
require under then existing law (including the Communications Act and the
written rules and regulations promulgated by the FCC), the prior approval of the
FCC, without first obtaining such approval. In connection with this Section
23(a), the Pledgee shall be entitled to rely in good faith upon an opinion of
outside FCC counsel of the Pledgee's choice with respect to such assignment or
transfer whether or not the advice rendered is ultimately determined to have
been accurate. To the extent such an opinion is requested, a copy of such
opinion shall be delivered to the Pledgor. The Pledgee specifically agrees that
to the extent required by the Communications Act (i) even after an Event of
Default shall have occurred, voting rights in the Collateral will remain with
the respective Pledgor until any and all required approval of the FCC shall be
obtained to the transfer of such voting rights, (ii) after an Event of Default
and a foreclosure on the Collateral by the
<PAGE>   26
Pledgee, there will be either a private or public sale of the Collateral, and
(iii) pursuant to Section 310(d) of the Communications Act, prior to the
exercise of stockholder rights by a purchaser at such sale, the prior consent of
the FCC will be obtained to such exercise.

                  (b) If an Event of Default shall have occurred and be
continuing, the Pledgors shall take any action which the Pledgee may reasonably
request in the exercise of its rights and remedies under this Agreement in order
to transfer or assign the Collateral to the Pledgee or to such one or more third
parties as the Pledgee may designate, or to a combination of the foregoing. To
enforce the provisions of this Section 23, upon an Event of Default the Pledgee
is empowered to seek from the FCC and any other governmental authority, to the
extent required, consent to or approval of any involuntary transfer of control
of any entity whose Collateral is subject to this Agreement for the purpose of
seeking a bona fide purchaser to whom control will ultimately be transferred.
Each Pledgor agrees to cooperate with any such purchaser and with the Pledgee in
the preparation, execution and filing of any forms and providing any information
that may be necessary or helpful in obtaining the FCC's consent to the
assignment to such purchaser of the Collateral. Each Pledgor hereby agrees to
consent to any such an involuntary transfer of control upon the request of the
Pledgee after and during the continuation of an Event of Default and, without
limiting any rights of the Pledgee under this Agreement, to authorize the
Pledgee to nominate a trustee or receiver to assume control of the Collateral,
subject only to required judicial, FCC or other consent required by governmental
authorities, in order to effectuate the transactions contemplated in this
Section 23. Such trustee or receiver shall have all the rights and powers as
provided to it by law or court order, or to the Pledgee under this Agreement.
Each Pledgor shall cooperate fully in obtaining the consent of the FCC and the
approval or consent of each other governmental authority required to effectuate
the foregoing.

                  (c) Each Pledgor shall use its best efforts to assist in
obtaining consent or approval of the FCC and any other governmental authority,
if required, for any action or transactions contemplated by this Agreement,
including, without limitation, the preparation, execution and filing with the
FCC of the transferor's or assignor's portion of any application or applications
for consent to the transfer of control or assignment necessary or appropriate
under the FCC's rules and regulations for approval of the transfer or assignment
of any portion of the Collateral. Anything herein to the contrary
notwithstanding, the Pledgors shall not be obligated to sign any such document
which such Pledgor has reasonable cause to believe contains any inaccuracy or to
make any statements concerning the qualifications of any transferee or assignee.

                  (d) Each Pledgor hereby acknowledges and agrees that the
Collateral is a unique asset and that a violation of the Pledgor's covenant to
cooperate with respect to any regulatory consents would result in irreparable
harm to the Pledgee for which monetary damages are not readily ascertainable.
The Pledgor further agrees that, because of the unique nature of its undertaking
in this Section 23, the same may be specifically enforced, and it hereby waives,
and agrees to waive, any claim or defense that the Pledgee would have an
adequate remedy at law for the breach of this undertaking.

                  (e) Without limiting the obligations of the Pledgors hereunder
in any respect, each Pledgor further agrees that if such Pledgor, upon or after
the occurrence of an Event of Default, should fail or refuse for any reason
whatsoever, without limitation, including any refusal
<PAGE>   27
pursuant to Section 23(c), to execute any application necessary or appropriate
to obtain any governmental consent necessary or appropriate for the exercise of
any right of the Pledgee hereunder, such Pledgor agrees that such application
may be executed on such Pledgor's behalf by the clerk of any competent
jurisdiction without notice to such Pledgor pursuant to court order.

                  24. ADDITIONAL PLEDGORS. Pursuant to Section 8.15 of the
Credit Agreement, certain Subsidiaries of a Borrower may after the date hereof
be required to enter into this Agreement as a Pledgor. Upon execution and
delivery, after the date hereof, by the Collateral Agent and such Subsidiary of
an instrument in the form of Exhibit A-2, such Subsidiary shall become a Pledgor
hereunder with the same force and effect as if originally named as a Pledgor
hereunder. Each Subsidiary which is required to become a party to this Agreement
shall so execute and deliver a copy of Exhibit A-2 to the Collateral Agent and,
at such time, shall execute a Pledge and Security Agreement Supplement in the
form of Exhibit A-1 to this Agreement with respect to all Collateral of such
Pledgor required to be pledged hereunder, which Supplement shall be completed in
accordance with Exhibit A-1. The execution and delivery of any such instrument
shall not require the consent of any other Pledgor hereunder. Upon the execution
and delivery by the Collateral Agent and such Subsidiary of an instrument in the
form of Exhibit A-2 as provided above, it is understood and agreed that the
pledge and security interests hereunder shall apply to all Collateral of such
additional Pledgor as provided in Section 3.1 hereof regardless of any failure
of any additional Pledgor to deliver, or any inaccurate information stated in,
the Pledge and Security Agreement Supplement.

                  25. RECOURSE. This Agreement is made with full recourse to the
Pledgors and pursuant to and upon all representations, warranties, covenants and
agreements on the part of the Pledgors contained herein and otherwise in writing
in connection herewith.

                  26. LIMITATION BY LAW; SEVERABILITY. All rights, remedies and
powers in this Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable law and may be limited to the extent
necessary so that they will not render this Agreement invalid or unenforceable,
in whole or in part.

                  27. PLEDGEE NOT BOUND. (a) Nothing herein shall be construed
to make the Pledgee or any other Secured Creditor liable as a member of any
limited liability company or any partnership and the Pledgee or any other
Secured Creditor by virtue of this Agreement or otherwise (except as referred to
in the following sentence) shall not have any of the duties, obligations or
liabilities of a member of any limited liability company or partnership. The
parties hereto expressly agree that, unless the Pledgee shall become the
absolute owner of the respective Pledged Limited Liability Interest or Pledged
Partnership Interest pursuant hereto, this Agreement shall not be construed as
creating a partnership or joint venture among the Pledgee, any other Secured
Creditor and/or any Pledgor.

                  (b) Except as provided in the last sentence of paragraph (a)
of this Section, the Pledgee, by accepting this Agreement, did not intend to
become a member of any limited liability company or partnership or otherwise be
deemed to be a co-venturer with respect to any Pledgor or any limited liability
company or partnership either before or after an Event of Default shall have
occurred. The Pledgee shall have only those powers set forth herein and shall
assume none
<PAGE>   28
of the duties, obligations or liabilities of a member of any limited liability
company or partnership or any Pledgor.

                  (c) The Pledgee shall not be obligated to perform or discharge
any obligation of any Pledgor as a result of the collateral assignment hereby
effected.

                  (d) The acceptance by the Pledgee of this Agreement, with all
the rights, powers, privileges and authority so created, shall not at any time
or in any event obligate the Pledgee to appear in or defend any action or
proceeding relating to the Collateral to which it is not a party, or to take any
action hereunder or thereunder, or to expend any money or incur any expenses or
perform or discharge any obligation, duty or liability under the Collateral.

                  28. CONTINUING PLEDGORS. The rights and obligations of each
Pledgor (other than the respective released Pledgor in the case of following
clause (y)) hereunder shall remain in full force and effect notwithstanding (x)
the addition of any new Pledgor as a party to this Agreement as contemplated by
preceding Section 24 or otherwise and/or (y) the release of any Pledgor under
this Agreement as contemplated by Section 21 or otherwise.

                  29. NO FRAUDULENT CONVEYANCE. Each Pledgor hereby confirms
that it is its intention that this Agreement not constitute a fraudulent
transfer or conveyance for purposes of any bankruptcy, insolvency or similar
law, the Uniform Fraudulent Conveyance Act or any similar Federal, state or
foreign law. To effectuate the foregoing intention, each Pledgor hereby
irrevocably agrees that its obligations and liabilities hereunder shall be
limited to the maximum amount as will, after giving effect to such maximum
amount and all other (contingent or otherwise) liabilities of such Pledgor that
are relevant under such laws, result in the obligations and liabilities of such
Pledgor hereunder in respect of such maximum amount not constituting a
fraudulent transfer or conveyance.

                  30. ALTERNATE CURRENCY REVOLVING LOAN BORROWERS. The Pledgors
hereby acknowledge that pursuant to the terms of the Credit Agreement various
Alternate Currency Revolving Loan Borrowers may become a party to the Credit
Agreement from time to time and incur Loans thereunder. The Pledgors further
acknowledge and agree that all obligations and liabilities of any Alternate
Currency Revolving Loan Borrower under the Credit Agreement shall be fully
secured hereunder as provided in Section 3.1 and no consent of the Pledgors is
required to effect the same.

                  31. MISCELLANEOUS. This Agreement shall be binding upon the
successors and assigns of each Pledgor and shall inure to the benefit of and be
enforceable by the Pledgee and its successors and assigns; provided that no
Pledgor may assign any of its rights or obligations hereunder without the prior
written consent of the Pledgee (with the consent of the Required Secured
Creditors and, if required by Section 13.12 of the Credit Agreement, all
Lenders). THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND
GOVERNED BY THE LAW OF THE STATE OF NEW YORK (WITHOUT REGARD TO PRINCIPLES OF
CONFLICT OF LAWS). The headings in this Agreement are for purposes of reference
only and shall not limit or define the meaning hereof. This Agreement may be
executed in any number of counterparts, each of which
<PAGE>   29
shall be an original, but all of which shall constitute one instrument.

                  32. STARWOOD REIT. Each Lender acknowledges and agrees that
the name "Starwood Hotels & Resorts" is a designation of Starwood REIT and its
Trustees (as Trustees but not personally) under a Declaration of Trust dated
August 25, 1969, as amended and restated as of June 6, 1988, as further amended
on February 1, 1995 and as further amended on June 19, 1995 and as the same may
be further amended from time to time, and all persons dealing with Starwood REIT
shall look solely to Starwood REIT's assets for the enforcement of any claims
against Starwood REIT, as the Trustees, officers, agents and security holders of
Starwood REIT assume no personal liability for obligations entered into on
behalf of Starwood REIT, and their respective individual assets shall not be
subject to the claims of any person relating to such obligations.
<PAGE>   30
                  IN WITNESS WHEREOF, each Pledgor has caused this Agreement to
be duly executed and delivered by its duly authorized officer on the date first
above written.

THE PLEDGEE

                  1. Appointment. The Secured Creditors, by their acceptance of
the benefits of the Pledge and Security Agreement to which this Annex G is
attached (the "Pledge Agreement") hereby irrevocably designate Bankers Trust
Company (and any successor Pledgee) to act as specified herein and therein.
Unless otherwise defined herein, all capitalized terms used herein (x) and
defined in the Pledge Agreement, are used herein as therein defined and (y) not
defined in the Pledge Agreement, are used herein as defined in the Credit
Agreement referenced in the Pledge Agreement. Each Secured Creditor hereby
irrevocable authorizes, and each holder of any Obligation by the acceptance of
such Obligation and by the acceptance of the benefits of the Pledge Agreement
shall be deemed irrevocably to authorize, the Pledgee to take such action on its
behalf under the provisions of the Pledge Agreement and any instruments and
agreements referred to therein and to exercise such powers and to perform such
duties thereunder as are specifically delegated to or required of the Pledge
Agreement by the terms thereof and such other powers as are reasonably
incidental thereto. The Pledgee may perform any of its duties hereunder or
thereunder by or through its authorized agents, sub-agents or employees.

                  2. Nature of Duties. (a) The Pledgee shall have no duties or
responsibilities except those expressly set forth herein or in the Pledge
Agreement. The duties of the Pledgee shall be mechanical and administrative in
nature; the Pledgee shall not have by reason of this Agreement, any other Credit
Document or any other Secured Debt Agreement a fiduciary relationship in respect
of any Secured Creditor; and nothing in this Agreement, any other Credit
Document or any other Secured Debt Agreement, expressed or implied, is intended
to or shall be so construed as to impose upon the Pledgee any obligations in
respect of the Pledge Agreement except as expressly set forth herein and
therein.

                  (b) The Pledgee shall not be responsible for insuring the
Collateral or for the payment of taxes, charges or assessments or discharging of
Liens upon the collateral or otherwise as to the maintenance of the Collateral.

                  (c) The Pledgee shall not be required to ascertain or inquire
as to the performance by any Pledgor of any of the covenants or agreements
contained in the Pledge Agreement, any other Credit Document or any other
Secured Debt Agreement.

                  (d) The Pledgee shall be under no obligation or duty to take
any action under, or with respect to, the Pledge Agreement if taking such action
(i) would subject the Pledgee to a tax in any jurisdiction where it is not then
subject to a tax or (ii) would require the Pledgee to qualify to do business, or
obtain any license, in any jurisdiction where it is not then so qualified or
licensed or (iii) would subject the Pledgee to in personam jurisdiction in any
locations where it is not then so subject.

                  (e) Notwithstanding any other provision of this Annex G,
neither the Pledgee nor any of its officers, directors, employees, affiliates or
agents shall, in its individual capacity, be personally liable for any action
taken or omitted to be taken by it in accordance with, or pursuant to this Annex
G or the Pledge Agreement except for its own gross negligence or willful

                                                                         Page 41


misconduct.

                  3. Lack of Reliance on the Pledgee. Independently and without
reliance upon the Pledgee, each Secured Creditor, to the extent it deems
appropriate, has made and shall continue to make (i) its own independent
investigation of the financial condition and affairs of each Pledgor and its
Subsidiaries in connection with the making and the continuance of the
Obligations and the taking or not taking of any action in connection therewith,
and (ii) its own appraisal of the creditworthiness of each Pledgor and its
Subsidiaries, and the Pledgee shall have no duty or responsibility, either
initially or on a continuing basis, to provide any Secured Creditor with any
credit or other information with respect thereto, whether coming into its
possession before the extension of any Obligations or the purchase of any notes
or at any time or times thereafter. The Pledgee shall not be responsible in any
manner whatsoever to any Secured Creditor for the correctness of any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability, perfection,
collectibility, priority or sufficiency of the Pledge Agreement or the security
interests granted hereunder or the financial condition of any Pledgor or any
Subsidiary of any Pledgor or be required to make any inquiry concerning either
the performance or observance of any of the terms, provisions or conditions of
the Pledge Agreement, or the financial condition of any Pledgor or any
Subsidiary of any Pledgor, or the existence or possible existence of any default
or event of default. The Pledgee makes no representations as to the value or
condition of the Collateral or any part thereof, or as to the title of any
Pledgor thereto or as to the security afforded by the Pledge Agreement.

                  4. Certain Rights of the Pledgee. (a) No Secured Creditor
shall have the right to cause the Pledgee to take any action with respect to the
Collateral, with only the Required Secured Creditors having the right to direct
the Pledgee to take any such action. If the Pledgee shall request instructions
from the Required Secured Creditors, with respect to any act or action
(including failure to act) in connection with the Pledge Agreement, the Pledgee
shall be entitled to refrain from such act or taking such action unless and
until it shall have received instructions from the Required Secured Creditors
and to the extent requested, appropriate indemnification in respect of actions
to be taken, and the Pledgee shall not incur liability to any Person by reason
of so refraining. Without limiting the foregoing, no Secured Creditor shall have
any right of action whatsoever against the Pledgee as a result of the Pledgee
acting or refraining from acting hereunder in accordance with the instructions
of the Required Secured Creditors. As used herein, the term "Required Secured
Creditors" shall mean (i) the Required Lenders (or, to the extent required by
Section 13.12 of the Credit Agreement, each of the Lenders) at all times prior
to the occurrence of the Credit Document Obligations Termination Date (as
defined in the Pledge and Security Agreement) and (ii) the holders of at least
the majority of the then outstanding Obligations secured hereby at all times
after the Credit Document Obligations Termination Date and prior to the
repayment in full, in cash, of all outstanding Obligations secured hereby.
Notwithstanding anything to the contrary contained in clause (i) or (ii) of the
immediately preceding sentence, if at any time the principal of any Obligations
secured hereby has been accelerated, or the final maturity date with respect to
any such principal Obligations has occurred, and as a result thereof one or more
payment Events of Default (where the aggregate

                                                                         ANNEX G
                                                                         Page 42



principal amount of such Obligations accelerated or not paid at final maturity
equals or exceeds $100,000,000), which payment Events of Default shall have
continued in existence for at least 90 consecutive days after the date of such
acceleration or final maturity, and the Required Secured Creditors at such time
(determined without regard to this sentence) have not directed the Pledgee to
commence enforcement proceedings pursuant to the Pledge Agreement, then so long
as such payment Event of Default is continuing the Secured Creditors holding at
least a majority of the outstanding Obligations secured hereby subject to such
payment Event of Default shall constitute the Required Secured Creditors for
purposes of causing the Pledgee to commence enforcement proceedings pursuant to
the Pledge Agreement, provided that in such event the Secured Creditors who
would constitute the Required Secured Creditors in the absence of this sentence
shall have the right to direct the manner and method of enforcement so long as
such directions do not materially delay or impair the taking of enforcement
action.

                  (b) Notwithstanding anything to the contrary contained herein,
the Pledgee is authorized, but not obligated, (i) to take any action reasonably
required to perfect or continue the perfection of the liens on the Collateral
for the benefit of the Secured Creditors and (ii) when instructions from the
Required Secured Creditors have been requested by the Pledgee but have not yet
been received, to take any action which the Pledgee, in good faith, believes to
be reasonably required to promote and protect the interests of the Secured
Creditors in the Collateral; provided that once instructions have been received,
the actions of the Pledgee shall be governed thereby and the Pledgee shall not
take any further action which would be contrary thereto.

                  (c) Notwithstanding anything to the contrary contained herein
or in the Pledge Agreement, the Pledgee shall not be required to take any action
that exposes or, in the good faith judgment of the Pledgee may expose, the
Pledgee or its officers, directors, agents or employees to personal liability,
unless the Pledgee shall be adequately indemnified as provided herein, or that
is, or in the good faith judgment of the Pledgee may be, contrary to the Pledge
Agreement, any Secured Debt Agreement or applicable law.

                  5. Reliance. The Pledgee shall be entitled to rely, and shall
be fully protected in relying, upon, any note, writing, resolution, notice,
statement, certificate, telex, teletype or telescopes message, cablegram,
radiogram, order or other document or telephone message signed, sent or made by
the proper Person or entity, and, with respect to all legal matters pertaining
hereto or to the Pledge Agreement and its duties thereunder and hereunder, upon
advice of counsel selected by it.

                  6. Indemnification. To the extent the Pledgee is not
reimbursed and indemnified by the Pledgors under the Pledge Agreement, the
Secured Creditors will reimburse and indemnify the Pledgee, in proportion to
their respective outstanding principal amounts (including, for this purpose, the
Stated Amount of outstanding Letters of Credit, as well as any unpaid Primary
Obligations in respect of Interest Rate Protection Agreements, as outstanding
principal) of Obligations, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature

                                                                         ANNEX G
                                                                         Page 43



whatsoever which may be imposed on, incurred by or asserted against the Pledgee
in performing its duties hereunder, or in any way relating to or arising out of
its actions as Pledgee in respect of the Pledge Agreement except for those
resulting solely from the Pledgee's own gross negligence or willful misconduct.
The indemnities set forth in this Section 6 shall survive the repayment of all
Obligations, with the respective indemnification at such time to be based upon
the outstanding principal amounts (determined as described above) of Obligations
at the time of the respective occurrence upon which the claim against the
Pledgee is based or, if same is not reasonably determinable, based upon the
outstanding principal amounts (determined as described above) of Obligations as
in effect immediately prior to the termination of the Pledge Agreement. The
indemnities set forth in this Section 6 are in addition to any indemnities
provided by the Lenders to the Pledgee pursuant to the Credit Agreement, with
the effect being that the Lenders shall be responsible for indemnifying the
Pledgee to the extent the Pledgee does not receive payments pursuant to this
Section 6 from the Secured Creditors (although in such event, and upon the
payment in full of all such amounts owing to the Pledgee by the Lenders, the
Lenders shall be subrogated to the rights of the Pledgee to receive payment from
the Secured Creditors).

                  7. The Pledgee in its Individual Capacity. With respect to its
obligations as a lender under the Credit Agreement and any other Credit
Documents to which the Pledgee is a party, and to act as agent under one or more
of such Credit Documents, the Pledgee shall have the rights and powers specified
therein and herein for a "Lender", or an "Agent", as the case may be, and may
exercise the same rights and powers as though it were not performing the duties
specified herein; and the terms "Lenders," "Required Lenders," "holders of
Notes," or any similar terms shall, unless the context clearly otherwise
indicates, include the Pledgee in its individual capacity. The Pledgee and its
affiliates may accept deposits from, lend money to, and generally engage in any
kind of banking, investment banking, trust or other business with any Pledgor or
any Affiliate or Subsidiary of any Pledgor as if it were not performing the
duties specified herein or in the other Credit Documents, and may accept fees
and other consideration from the Pledgors for services in connection with the
Credit Agreement, the other Credit Documents and otherwise without having to
account for the same to the Secured Creditors.

                  8. Holders. The Pledgee may deem and treat the payee of any
note as the owner thereof for all purposes hereof unless and until written
notice of the assignment, transfer or endorsement thereof, as the case may be,
shall have been filed with the Pledgee. Any request, authority or consent of any
person or entity who, at the time of making such request or giving such
authority or consent, is the holder of any note, shall be final and conclusive
and binding on any subsequent holder, transferee, assignee or endorsee, as the
case may be, of such note or of any note or notes issued in exchange therefor.

                  9. Resignation by the Pledgee. (a) The Pledgee may resign from
the performance of all of its functions and duties hereunder and under the
Pledge Agreement at any time by giving 15 Business Days' prior or written notice
to the Parent Companies and the Secured Creditors. Such resignation shall take
effect upon the appointment of a successor Pledgee pursuant to clause (b) or (c)
below.
<PAGE>   95
                                                                         ANNEX G

                  (b) If a successor Pledgee shall not have been appointed
within said 15 Business Day period by the Required Secured Creditors, the
Pledgee, with the consent of the Parent Companies, which consent shall not be
unreasonably withheld or delayed, shall then appoint a successor Pledgee who
shall serve as Pledgee hereunder or thereunder until such time, if any, as the
Required Secured Creditors appoint a successor Pledgee as provided above.

                  (c) If no successor Pledgee has been appointed pursuant to
clause (b) above by the 15th Business Day after the date of such notice of
resignation was given by the Pledgee, as a result of a failure by the Parent
Companies to consent to the appointment of such a successor Pledgee, the
Required Secured Creditors shall then appoint a successor Pledgee who shall
serve as Pledgee hereunder or thereunder until such time, if any, as the
Required Secured Creditors appoint a successor Pledgee as provided above.

                           (immediately before giving effect to this Supplement)
                           and BANKERS TRUST COMPANY as collateral agent and as
                           pledgee (in such capacities, the "Pledgee") for the
                           Secured Creditors (such term and each other
                           capitalized term used but not defined having the
                           meaning given it in the Pledge and Security Agreement
                           referred to below).

                 A. The Pledgors have entered into the Pledge and Security
Agreement in order to induce the Secured Creditors to make loans and other
extensions of credit constituting Obligations as defined in the Pledge and
Security Agreement. Pursuant to Section 8.15 of the Credit Agreement, certain
Subsidiaries of the Borrowers are, after the date of the Pledge and Security
Agreement, required to enter into the Pledge and Security Agreement as a
Pledgor. Section 24 of the Pledge and Security Agreement provides that
additional Subsidiaries may become Pledgors under the Pledge and Security
Agreement by execution and delivery of an instrument in the form of this
Supplement. The undersigned (the "New Pledgor") is a Subsidiary of a Borrower
and is executing this Supplement in accordance with the requirements of the
Credit Agreement and/or the Pledge and Security Agreement to become a Pledgor
under the Pledge and Security Agreement in order to induce the Secured Creditors
to extend, or maintain, Obligations.

                 Accordingly, the Pledgee and the New Pledgor agree as follows:

                 SECTION 1. The New Pledgor by its signature below becomes a
Pledgor under the Pledge and Security Agreement with the same force and effect
as if originally named therein as a Pledgor and the New Pledgor hereby agrees to
all the terms and provisions of the Pledge and Security Agreement applicable to
it as a Pledgor thereunder. Each reference to a "Pledgor" in the Pledge and
Security Agreement shall be deemed to include the New Pledgor. The Pledge and
Security Agreement is hereby incorporated herein by reference.

                 SECTION 2. The New Pledgor represents and warrants to the
Secured Creditors that this Supplement has been duly authorized, executed and
delivered by it and constitutes its legal, valid and binding obligation,
enforceable against it in accordance with its terms, subject to the effects of
applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally and equitable principles of general applicability.

                 SECTION 3. This Supplement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute but

                                                                        ANNEX 1
                                                                         Page 53


one instrument. This Supplement shall become effective when the Pledgee shall
have received counterparts of this Supplement that, when taken together, bear
the signatures of the New Pledgor and the Pledgee.

                 SECTION 4. Except as expressly supplemented hereby, the Pledge
and Security Agreement shall remain in full force and effect.

                 SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                 SECTION 6. In case any one or more of the provisions contained
in this Supplement should be held invalid, illegal or unenforceable in any
respect, neither party hereto shall be required to comply with such provision
for so long as such provision is held to be invalid, illegal or unenforceable,
but the validity, legality and enforceability of the remaining provisions
contained herein and in the Pledge and Security Agreement shall not in any way
be affected or impaired. The parties hereto shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

                 SECTION 7. All communications and notices hereunder shall be in
writing and given as provided in the Pledge and Security Agreement. All
communications and notices hereunder to the New Pledgor shall be given to it at
the address set forth under its signature, with a copy to the Parent Companies.

executed this Supplement to the Pledge and Security Agreement as of the day and
year first above written.
