                  (b) give, execute, deliver, file or record any and all
financing statements, notices, contracts, agreements or other instruments,

                      Amended and Restated Pledge Agreement


                                      -3-

the Collateral Agent to exercise and enforce its rights, remedies, powers
and privileges under this Agreement with respect to such Liens, including
causing any or all of the Equity Collateral to be transferred of record into the
name of the Collateral Agent (and the Collateral Agent agrees that if any Equity
Collateral is transferred into its name, the Collateral Agent will thereafter
promptly give to the Pledgor copies of any notices and communications received
by it with respect to the Equity Collateral pledged by the Pledgor). 

                  2.04 ATTORNEY-IN-FACT. Subject to the rights of the Pledgor
under Section 2.05, the Collateral Agent is hereby appointed the
attorney-in-fact of the Pledgor for the purpose of carrying out the provisions
of this Agreement and taking any action and executing any instruments as are
reasonably necessary to accomplish the purposes of this Agreement, to preserve
the validity, perfection and priority of the Liens granted by this Agreement
and, following any Termination Event, to exercise its rights, remedies, powers
and privileges under this Agreement. This appointment as attorney-in-fact is
irrevocable and coupled with an interest. Without limiting the generality of the
foregoing, the Collateral Agent shall be entitled under this Agreement upon the
occurrence and continuation of any Termination Event (i) to ask, demand,
collect, sue for, recover, receive and give receipt and discharge for amounts
due and to become due under and in respect of all or any part of the Collateral;
(ii) to receive, endorse and collect any drafts, instruments, documents and
chattel paper in connection with clause (i) above; (iii) to file any claims or
take any action or proceeding as is reasonably necessary for the collection of
all or any part of the Collateral; and (iv) to execute, in connection with any
sale or disposition of the Collateral under Section 5, any endorsements,
assignments, bills of sale or other instruments of conveyance or transfer with
respect to all or any part of the Collateral. 

                  2.05 SPECIAL PROVISIONS RELATING TO EQUITY COLLATERAL. 

                  (a) So long as no Termination Event shall have occurred and be
continuing, the Pledgor shall have the right to exercise all voting, consensual
and other powers of ownership pertaining to the Equity Collateral for all
purposes not inconsistent with the terms of this Agreement; PROVIDED that the
Pledgor agrees that it will not vote the Equity Collateral in any manner that is
inconsistent with the terms of this Agreement; and the Collateral Agent shall,
at the Pledgor's expense, execute and deliver to the Pledgor or cause to be
executed and delivered to the Pledgor all such proxies, powers of attorney,
dividend or distribution and other orders and other instruments, without
recourse, as the Pledgor may reasonably request for the purpose of enabling the
Pledgor to exercise the rights and powers which it is entitled to exercise
pursuant to this Section 2.05(a). 

                  (b) So long as no Termination Event shall have occurred and be
continuing, the Pledgor shall be entitled to receive and retain any dividends or
other distributions on the Equity Collateral. 

                  (c) If any Termination Event shall have occurred and be
continuing, and whether or not the Collateral Agent exercises any available
right to declare any Secured Obligation due and payable or seeks or pursues any
other right, remedy, power or privilege available to it under applicable law or
this Agreement, all dividends and other distributions on the Equity Collateral
shall be paid directly to the Collateral Agent as part of the Equity Collateral,
subject to the terms of this Agreement, and, if the Collateral Agent shall so
request, 


                      Amended and Restated Pledge Agreement



                                      -4-
<PAGE>   5

the Pledgor agrees to execute and deliver to the Collateral Agent appropriate
additional dividend, distribution and other orders and instruments to that end;
provided that if such Termination Event is cured or rescinded, any such dividend
or distribution paid to the Collateral Agent prior to such cure shall, upon
request of the Pledgor (except to the extent applied to the Secured
Obligations), be returned by the Collateral Agent to the Pledgor.

                  2.06 RIGHTS AND OBLIGATIONS. 

                  (a) No reference in this Agreement to proceeds or to the sale
or other disposition of Collateral shall authorize the Pledgor to sell or
otherwise dispose of any Collateral except to the extent otherwise expressly
permitted by the terms of this Agreement. 

                  (b) The Collateral Agent shall not be required to take steps
necessary to preserve any rights against prior parties to any part of the
Collateral. 

                  (c) The Pledgor shall remain liable to perform its duties and
obligations under the LLC Agreement in accordance with its terms to the same
extent as if this Agreement had not been executed and delivered. The exercise by
the Collateral Agent of any right, remedy, power or privilege in respect of this
Agreement shall not release the Pledgor from any of its duties and obligations
under the LLC Agreement. The Collateral Agent shall have no duty, obligation or
liability under the LLC Agreement by reason of this Agreement. 

                  2.07 TERMINATION. When all Secured Obligations have been
satisfied in full, this Agreement shall terminate, and the Collateral Agent
shall forthwith cause to be assigned, transferred and delivered, against receipt
but without any recourse, warranty or representation whatsoever, any remaining
Collateral and money received in respect of the Collateral, to or on the order
of the Pledgor. 

                  SECTION 3. REPRESENTATIONS AND WARRANTIES. As of the date of
this Agreement, the Pledgor represents and warrants to the Collateral Agent as
follows: 

                  3.01 TITLE. The Pledgor is the sole beneficial owner of the
Collateral in which it purports to grant a Lien pursuant to this Agreement, and
such Collateral is free and clear of all Liens (and, with respect to the Equity
Collateral, of any Equity Right in favor of any other Person), other than the
Western Realty Liens. The Liens granted by this Agreement in favor of the
Collateral Agent for the benefit of the Participating Holders have attached and
constitute a perfected security interest in all of such Collateral prior to all
other Liens. 

                  3.02 PLEDGED EQUITY. 

                  (a) The Pledged Equity evidenced by the certificates
identified in Exhibit A is duly authorized, validly existing, fully paid and
nonassessable, and none of such Pledged Equity is subject to any contractual
restriction, or any restriction under the organizational documents of the Issuer
of such Pledged Equity, upon the transfer of such Pledged Equity (except for any
such restriction contained in this Agreement). 



                      Amended and Restated Pledge Agreement



                                      -5-
<PAGE>   6

                  (b) The Equity Collateral constitutes 50.10% of the total
number of membership interests or shares of each class of capital stock, as
applicable, of the Issuer currently outstanding. The attached Exhibit A
correctly identifies, as of the date of this Agreement, the membership interests
comprising such Pledged Equity and the respective percentage interest in the
Issuer as a whole. All such membership interests or shares are duly authorized,
validly issued, fully paid and nonassessable and will be free of any contractual
restriction (other than the Western Realty Lien) or any restriction under the
charter or bylaws of the Issuer of the Equity Collateral, upon the transfer of
the Equity Collateral (except for any such restriction contained in this
Agreement). 

                  SECTION 4. COVENANTS. 

                  4.01 BOOKS AND RECORDS. The Pledgor shall: 

                  (a) keep full and accurate books and records relating to the
Collateral and stamp or otherwise mark such books and records in such manner as
the Collateral Agent may reasonably require in order to reflect the Liens
granted by this Agreement; and 

                  (b) permit representatives of the Collateral Agent, upon
reasonable notice, at any time during normal business hours to inspect and make
abstracts from its books and records pertaining to the Collateral, permit
representatives of the Collateral Agent to be present at the Pledgor's place of
business to receive copies of all communications and remittances relating to the
Collateral and forward copies of any notices or communications received by the
Pledgor with respect to the Collateral, all in such manner as the Collateral
Agent may reasonably request. 

                  4.02 REMOVALS, ETC. Without at least 30 days' prior written
notice to the Collateral Agent, the Pledgor shall not (i) maintain any of its
books and records with respect to the Collateral at any office or maintain its
principal place of business at any place, other than at the address initially
indicated for notices to it under Section 6(c) or (ii) change its corporate
name, or the name under which it does business, from the name shown on the
signature pages to this Agreement. 

                  4.03 SALES AND OTHER LIENS. Except as permitted under the
Indenture, the Pledgor shall not sell, transfer or otherwise dispose of all or
any part of the Collateral, create, incur, assume or suffer to exist any Lien
upon all or any part of the Collateral or file or suffer to be on file or
authorize to be filed, in any jurisdiction, any financing statement or like
instrument with respect to all or any part of the Collateral in which the
Collateral Agent is not named as the sole secured party for the benefit of the
Participating Holders (other than or in connection with the Western Realty
Lien).

                  4.04 FURTHER ASSURANCES. The Pledgor agrees that, from time to
time upon the written request of the Collateral Agent, the Pledgor will execute
and deliver such further documents and do such other acts and things as the
Collateral Agent may reasonably request in order fully to effect the purposes of
this Agreement. 

                  4.05 DILUTION. The Pledgor shall cause the Equity Collateral
to constitute at all times 50.10% of the total equity interests in the Issuer.
The Pledgor shall cause all such interests 


                      Amended and Restated Pledge Agreement



                                      -6-
<PAGE>   7

to be duly authorized, validly issued, fully paid and nonassessable and to be
free of any contractual restriction (other than the Western Realty Lien) or any
restriction under the Limited Liability Company Agreement, upon the transfer of
such Equity Collateral.

                  4.06 FINANCIAL REPORTS. Within 45 days after the close of the
first three quarterly accounting periods in each fiscal year of the Pledgor, the
Pledgor shall deliver to the Collateral Agent, the unaudited financial
statements of the Pledgor and the Issuer. Within 120 days after the close of
each fiscal year, the Pledgor shall deliver to the Collateral Agent, the
financial statements of the Pledgor and the Issuer, certified by an independent
certified public accountant of recognized national standing. The Pledgor
represents and warrants that all such financial statements shall be true and
correct in all material respects. 

                  SECTION 5. REMEDIES.

                  5.01 EVENTS OF DEFAULT, ETC. If a Termination Event shall have
occurred and be continuing:

                  (a) the Collateral Agent in its discretion may, in its name or
in the name of the Pledgor or otherwise, demand, sue for, collect or receive any
money or property at any time payable or receivable on account of or in exchange
for all or any part of the Collateral, but shall be under no obligation to do
so; 

                  (b) the Collateral Agent in its discretion may, upon ten
business days' prior written notice to the Pledgor of the time and place and
subject to the terms of the LLC Agreement, with respect to all or any part of
the Collateral which shall then be or shall thereafter come into the possession,
custody or control of the Collateral Agent or its agents, sell, lease or
otherwise dispose of all or any part of such Collateral, at such place or places
as the Collateral Agent deems best, for cash, for credit or for future delivery
(without thereby assuming any credit risk) and at public or private sale,
without demand of performance or notice of intention to effect any such
disposition or of time or place of any such sale (except such notice as is
required above or by applicable statute and cannot be waived), and the
Collateral Agent or any other Person may be the purchaser, lessee or recipient
of any or all of the Collateral so disposed of at any public sale (or, to the
extent permitted by law, at any private sale) and thereafter hold the same
absolutely, free from any claim or right of whatsoever kind, including any right
or equity of redemption (statutory or otherwise), of the Pledgor, any such
demand, notice and right or equity being hereby expressly waived and released.
The Collateral Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for the sale, and such sale may be made at any time
or place to which the sale may be so adjourned; and 

                  (c) the Collateral Agent shall have, and in its discretion may
exercise, all of the rights, remedies, powers and privileges with respect to the
Collateral of a secured party under the Uniform Commercial Code (whether or not
the Uniform Commercial Code is in effect in the jurisdiction where such rights,
remedies, powers and privileges are asserted) and such additional rights,
remedies, powers and privileges to which a secured party is entitled under the
laws in effect in any jurisdiction where any rights, remedies, powers and
privileges in respect of this Agreement or the Collateral may be asserted,
including the right, to the maximum extent 



                      Amended and Restated Pledge Agreement



                                      -7-
<PAGE>   8

permitted by law (subject to the terms of the LLC Agreement), to exercise all
voting, consensual and other powers of ownership pertaining to the Collateral as
if the Collateral Agent was the sole and absolute owner of the Collateral (and
the Pledgor agrees to take all such action as may be appropriate to give effect
to such right).

                  The proceeds of, and other realization upon, the Collateral by
virtue of the exercise of remedies under this Section 5.01 shall be applied in
accordance with Section 5.04. 

                  5.02 LIMITED RECOURSE. Notwithstanding anything to the
contrary in this Agreement, the Limited Recourse Guarantee, the Standstill
Agreement, the Indenture or otherwise, the security interest granted herein
secures a limited recourse obligation and recourse for the Secured Obligations
is expressly limited solely to the Collateral Agent's and Participating Holders'
interest in the Collateral. 

                  5.03 PRIVATE SALE. 

                  (a) The Collateral Agent and the Participating Holders shall
incur no liability as a result of the sale, lease or other disposition of all or
any part of the Collateral at any private sale pursuant to Section 5.01
conducted in a commercially reasonable manner. The Pledgor hereby waives any
claims against the Collateral Agent or a Participating Holder arising by reason
of the fact that the price at which the Collateral may have been sold at such a
private sale was less than the price which might have been obtained at a public
sale or was less than the aggregate amount of the Secured Obligations, even if
the Collateral Agent accepts the first offer received and does not offer the
Collateral to more than one offeree. 

                  (b) The Pledgor recognizes that, by reason of certain
prohibitions contained in the Securities Act of 1933 and applicable state
securities laws, the Collateral Agent may be compelled, with respect to any sale
of all or any part of the Collateral, to limit purchasers to those who will
agree, among other things, to acquire the Collateral for their own account, for
investment and not with a view to distribution or resale. The Pledgor
acknowledges that any such private sales may be at prices and on terms less
favorable to the Pledgor than those obtainable through a public sale without
such restrictions, and, notwithstanding such circumstances, agrees that any such
private sale shall be deemed to have been made in a commercially reasonable
manner and that the Collateral Agent shall have no obligation to engage in
public sales and no obligation to delay the sale of any Collateral for the
period of time necessary to permit the Issuer of the Collateral to register it
for public sale. 

                  5.04 APPLICATION OF PROCEEDS. Except as otherwise expressly
provided in this Agreement, the proceeds of, or other realization upon, all or
any part of the Collateral by virtue of the exercise of remedies under Section
5.01, and any other cash at the time held by the Collateral Agent under this
Section 5, shall be applied by the Collateral Agent:

                  FIRST, to the payment of the reasonable costs and expenses of
such exercise of remedies, including reasonable out-of-pocket costs and expenses
of the Collateral Agent and the reasonable fees and expenses of its counsel;



                      Amended and Restated Pledge Agreement



                                      -8-
<PAGE>   9

                  NEXT, to the payment in full of the remaining Secured
Obligations equally and ratably in accordance with the their respective amounts
then due and owing; and

                  FINALLY, to the Pledgor, or its respective successors or
assigns, or as a court of competent jurisdiction may direct, of any surplus then
remaining.

                  As used in this Section 5, "PROCEEDS" of Collateral shall mean
cash, securities and other property realized in respect of, and distributions in
kind of, Collateral, including any property received under any bankruptcy,
reorganization or other similar proceeding as to the Pledgor or any issuer of,
or account debtor or other obligor on, any of the Collateral. 

                  SECTION 6.MISCELLANEOUS.

                  (a) NO WAIVER No failure on the part of the Collateral Agent
to exercise and no delay in exercising, and no course of dealing with respect
to, any right, remedy, power or privilege under this Agreement shall operate as
a waiver of such right, remedy, power or privilege, nor shall any single or
partial exercise of any right, remedy, power or privilege under this Agreement
preclude any other or further exercise of any such right, remedy, power or
privilege or the exercise of any other right, remedy, power or privilege. The
