California and all other applicable law, in addition to, and not in limitation
of, the other rights, remedies and recourse granted to the Master Collateral

maintain the Collateral received by it and all records and documents relating
thereto at the office of the Master Collateral Agent or such other address as
may be approved by the Controlling Party. The Master Collateral Agent shall keep
or cause to be kept all Collateral and related documentation in its possession
separate and apart from all other property that it is holding in its possession
and from its own general assets and shall maintain accurate records pertaining
to the Collateral and the Collateral Account in such a manner as shall enable
the Master Collateral Agent and the Controlling Party to verify the accuracy of
such record-keeping. The Master Collateral Agent's books and records shall at

agent for the Trustee and the Collateral Agent and is not the property of the
Master Collateral Agent. The Master Collateral Agent will promptly report to
Financial Security, the Trustee, the Bank and WFAL 2 any failure on its part to
hold the Collateral as provided in this Section 2.03(a) and will promptly take
appropriate action to remedy any such failure.

                  (b) Access. The Master Collateral Agent shall permit Financial
Security or the Trustee, or their respective duly authorized representatives,
attorneys, auditors or designees, to inspect the Collateral in the possession of
or otherwise under the control of the Master Collateral Agent pursuant hereto at
such reasonable times during normal business hours as Financial Security or the
Trustee may reasonably request with prior written notice. Prior to a Default
such inspection shall be at the expense of Financial Security or the Trustee, as
the case may be, but after a Default such inspection shall be at the expense of
the Bank and WFAL 2.

         amended from time to time by a writing signed only by Financial
         Security, the Bank and WFAL 2.

                  (e) Liquidity. In order to ensure that WFAL 2 has sufficient
funds to satisfy its repayment obligations pursuant to Section 4 of each
Reinvestment Contract, the Bank hereby agrees to lend WFAL 2 sufficient
immediately available funds in order to enable WFAL 2 timely to perform its
obligations under each such Sections and any other payments obligations due by

to be made available, to WFAL 2 immediately available funds for such purpose.

Security, the Trustee or otherwise, for the sole use and benefit of the Master
Collateral Agent, the Trustee and Financial Security, but at the expense of the
Bank and WFAL 2, to the extent permitted by law, to exercise, at any time while

         with the same or the proceeds or avails thereof, as fully and
         effectually as if the Master Collateral Agent were the absolute owner

                         (iv) to extend the time of payment of any or all
         thereof and to make any allowance and other adjustments with reference

hereof, general standing instructions) given to the Master Collateral Agent by

proceeds thereof to the payment of the Master Secured Obligations in the manner
specified in Section 3.03(c) hereof. If no such instruction with respect to
investment of any portion of the Collateral Account is received by the Master
Collateral Agent, no investment shall be made of such portion and the Master
Collateral Agent shall not be liable for any resulting absence of income.

                  (d) On each Business Day specified by the Controlling Party
after delivery of an FSA Notice, the Master Collateral Agent shall withdraw from
the Collateral Account an amount (up to the balance therein) that is sufficient

successor Master Collateral Agent in its commercial banking capacity), the name

the Collateral Account, the Collateral Account number and the individuals whose
names appear on the signature cards for the Collateral Account. The Bank and
WFAL 2 shall cause such depository institution to execute a written agreement,
in form and substance satisfactory to the Controlling Party, waiving, in each
case to the extent permitted under applicable law, (i) any banker's or other
statutory or similar Lien, and (ii) any right of setoff or other similar right
under applicable law with respect to the Collateral Account and agreeing to
notify the Bank, WFAL 2, the Master Collateral Agent, Financial Security and the
Trustee of any charge or claim against or with respect to the Collateral
Account. The Master Collateral Agent shall give the Bank, WFAL 2, Financial
Security and the Trustee at least ten (10) Business Days' prior written notice
of any change in the location of the Collateral Account or in any related
account information. Anything herein to the contrary notwithstanding, unless
otherwise consented to by the Controlling Party in writing, the Master
Collateral Agent shall have no right to change the location of the Collateral
Account.

Eligible Account, the Master Collateral Agent shall establish, in accordance
with paragraph (a) of this Section, a successor Collateral Account thereto which
shall be an Eligible Account at Bankers Trust Company of California, N.A. or at
another depository institution acceptable to the Controlling Party.

                  (c) Any investment of funds in the Collateral Account shall be
made in accordance with the provisions of Section 3.02(c) hereof in the name of
the Master Collateral Agent (in its capacity as such). Subject to the other
provisions hereof, the Master Collateral Agent shall have sole control over each
such investment and the income thereon, and any certificate or other instrument
evidencing any such investment, if any, shall be delivered directly to the
Master Collateral Agent, together with each document of transfer, if any,
necessary to transfer title to such investment to the Master Collateral Agent in
a manner which complies with Article II and this Section.

                  (d) Subject to Section 4.03 hereof, the Master Collateral
Agent shall not be liable by reason of any insufficiency in the Collateral
Account resulting from any loss on any investment included therein except for
losses attributable to the Master Collateral Agent's failure to make payments on
investments as to which the Master Collateral Agent, in its commercial capacity,
is obligated.

         Section 3.05. FSA Notices. The Controlling Party may at any time give
notice (an "FSA Notice") to the Master Collateral Agent stating that (i) a
Default has occurred and is continuing or (ii) the Controlling Party has,

Contract as an eligible investment under a Trust Agreement or other Existing
Agreement.

Agent with respect to the Collateral, and Bankers Trust Company of California,
N.A. hereby accepts such appointment and agrees to act as Master Collateral
Agent hereunder. The Collateral Agent, the Trustee and each Depositor in their
capacities as pledgees hereunder hereby authorize the Master Collateral Agent to
take such action on their behalf, and to exercise such rights, remedies, powers
and privileges hereunder as the Controlling Party may direct and as are
specifically authorized to be exercised by the Master Collateral Agent by the
terms hereof, together with such actions, rights, remedies, powers and
privileges as are reasonably incidental thereto. The Master Collateral Agent
shall execute the Servicing Agreement and shall act upon and in compliance with
the written instructions of the Controlling Party delivered pursuant to this
Agreement promptly following receipt of such written instructions.

                  (b) The Master Collateral Agent is, and shall at all times
during the term of this Agreement be, a Securities Intermediary for Financial
Security.

                  (c) The Master Collateral Agent is eligible to maintain, and
does maintain, and will continue to be eligible to maintain and will maintain,
one or more accounts in its name (or the name of a nominee) with each Clearing
Corporation through which Securities or Security Entitlements constituting
Collateral are held.

         Section 4.02. Performance of Duties. The Master Collateral Agent may
perform any of its duties hereunder by or through agents and employees, shall be
entitled to retain counsel and act in reliance upon the written advice of such
counsel concerning all matters pertaining to the agencies hereby created or its
duties hereunder and shall not be liable for actions taken, or omitted to be
taken, in good faith reliance upon the opinion of counsel selected by it. The
duties of the Master Collateral Agent shall be mechanical and administrative in
nature. The Master Collateral Agent shall not have by reason of this Agreement a
fiduciary relationship. Nothing in this Agreement, express or implied, is
intended to or shall be construed as to impose upon the Master Collateral Agent
any obligations in respect of this Agreement except as expressly set forth
herein.

         Section 4.03. Limitation on Liability; Indemnification. Neither the
Master Collateral Agent nor any of its directors, officers or employees, shall

Collateral Agent be responsible for the validity, effectiveness, value,
sufficiency or enforceability against the Bank or WFAL 2 of this Agreement or
any of the Collateral (or any part thereof).

                  The Bank and WFAL 2 hereby jointly and severally agree to
indemnify and hold the Master Collateral Agent harmless from and against all
damage, liability and expense (including reasonable attorneys' fees) arising out
of or in connection with this Agreement, except to the extent such damage,
liability or expense arises out of the Master Collateral Agent's negligence,
willful misconduct or breach of the obligations imposed hereby on the Master
Collateral Agent.

         Section 4.04. Reliance upon Documents. Subject to the provisions of
Section 4.08 hereof, in the absence of gross negligence or willful misconduct on
its part, the Master Collateral Agent shall be entitled to rely on any
communication, instrument, paper or other document reasonably believed by it to
be genuine and correct and to have been signed or sent by the proper Person and
shall have no liability in acting, or omitting to act, where such action or
omission to act is in reasonable reliance upon any statement or opinion
contained in any such document or instrument.

         Section 4.05. Successor Master Collateral Agent. The Master Collateral
Agent acting hereunder at any time may resign by giving not less than ninety
(90) days' prior written notice in writing to the Bank, WFAL 2, the Trustee and
Financial Security. If the Master Collateral Agent is also a Trustee and, as
such, determines that it has a conflicting interest on account of its acting as
Master Collateral Agent, the Master Collateral Agent shall eliminate such
conflicting interest by resigning as Master Collateral Agent hereunder rather
than resigning as such Trustee. The Controlling Party shall appoint a successor
to the Master Collateral Agent upon any such resignation by an instrument of
substitution complying with the requirements of applicable law, or, in the
absence of any such requirements, without formality other than appointment and
designation in writing, a copy of which instrument or writing shall be sent to
the Bank and WFAL 2; provided, however, that the validity of any such
appointment shall not be impaired or affected by any failure to give any such
notice to the Bank and WFAL 2 or by any defect therein. Notwithstanding the
foregoing, prior to the receipt by the Bank and WFAL 2 of an FSA Notice, such
appointment shall be subject to the consent of the Bank and WFAL 2, which
consent shall not be unreasonably withheld. Upon the making and acceptance of
such appointment, the execution and delivery by such successor Master Collateral
Agent of a ratifying instrument pursuant to which such successor Master
Collateral Agent agrees to assume the duties and obligations imposed on the
Master Collateral Agent by the terms of this Agreement, and the delivery to such
successor Master Collateral Agent of the Collateral and related documents then
held by the retiring Master Collateral Agent, such successor Master Collateral
Agent shall thereupon succeed to and become vested with all the estate, rights,
powers, remedies, privileges, immunities, indemnities, duties and obligations
hereby granted to or conferred or imposed upon the Master Collateral Agent named
herein, and one such appointment and designation shall not exhaust the right to
appoint and designate further successor Master Collateral Agents hereunder. No
Master Collateral Agent shall be discharged from its duties or obligations
hereunder until the Collateral and related documents then held by such Master
Collateral Agent shall have been transferred and delivered to the successor
Master Collateral Agent and such retiring Master Collateral Agent shall have
executed and delivered to the successor Master Collateral Agent appropriate
instruments establishing the successor Master Collateral Agent as the record
holder of all liens and security interests in favor of the Trustee and the
Collateral Agent in the Collateral and transferring to such successor Master
Collateral Agent all power given pursuant to this Agreement to act as
attorney-in-fact of the Bank and WFAL 2, and each of them, for purposes of this
Agreement. Each such successor Master Collateral Agent shall provide the Bank,
WFAL 2 and Financial Security with its address, and its telephone and telecopier
numbers, to be used for purposes of Section 7.05 hereof, in a notice complying
with the terms of said Section.

         Section 4.06. Representations and Warranties of Bankers Trust Company
of California, N.A.. Bankers Trust Company of California, N.A. represents and
warrants to the Bank, WFAL 2, the Trustee and Financial Security as follows:

                  (a) Bankers Trust Company of California, N.A. is a national
banking association, duly organized, validly existing and in good standing.

                  (b) Bankers Trust Company of California, N.A. has full power,
authority and legal right to execute, deliver and perform this Agreement and the
Servicing Agreement and has taken all necessary action to authorize the
execution, delivery and performance by it of this Agreement and the Servicing
Agreement.

                  (c) This Agreement and the Servicing Agreement constitute
valid and binding obligations of Bankers Trust Company of California, N.A. in
its capacity as Master Collateral Agent enforceable against it in accordance
with their respective terms.

                  (d) The execution and delivery by Bankers Trust Company of
California, N.A. of this Agreement and the Servicing Agreement and the
performance by it of its obligations hereunder and thereunder, will not violate
any law, rule or regulation or any agreement, order or decree binding on it or
its properties.

         Section 4.07. Waiver of Setoffs. The Master Collateral Agent hereby
expressly waives any and all rights of setoff that the Master Collateral Agent
may otherwise at any time have under applicable law with respect to the
Collateral Account and agrees that amounts in the Collateral Account shall at
all times be held and applied solely in accordance with the provisions of this
Agreement.

         Section 4.08. Control by the Controlling Party. The Master Collateral
Agent shall comply with notices and instructions given by the Bank or WFAL 2
only if expressly contemplated hereby or if accompanied by the written consent
of the Controlling Party, except that if any Default shall have occurred and be
continuing, the Master Collateral Agent shall act upon and comply with notices
and instructions given by the Controlling Party alone in the place and stead of
the Bank or WFAL 2. In the absence of any written communication by the
Controlling Party to the Master Collateral Agent to the effect that a Default
has occurred and is continuing, the Master Collateral Agent may assume that no
Default has occurred and is continuing. The Master Collateral Agent shall have
no duty to verify whether or not a Default has occurred or is continuing or the
facts stated in any FSA Notice. Any written communication by the Controlling
Party to the Master Collateral Agent specifying the amount of any obligations
owing to Financial Security or the Trustee shall be conclusive evidence of such
amount, notwithstanding any notice to the contrary received by the Master
Collateral Agent from the Bank, WFAL 2 or any other Person.

for the benefit of the Master Collateral Agent a valid first Lien on, and valid
and perfected, first priority security interest in, (a) prior to delivery of an
FSA Notice to the Master Collateral Agent, the items of Collateral referenced in
Schedule A hereto and (b) after delivery of an FSA Notice to the Master
Collateral Agent, all Collateral so delivered and to deliver such Collateral to

Monthly Statement following each January and July, commencing with such date

that have been granted to the Master Collateral Agent as of the last Business
Day of the relevant January or July under California law (and other applicable

case may be, and reciting the details of such action, or (b) no action is
necessary to maintain such perfected lien and security interest. Such Opinion of
Counsel shall describe each execution and filing of any documents and
instruments and such other actions as will, in the opinion of such counsel, be
required to perfect, maintain and protect the lien and security interest of the

as the case may be, shall promptly give notice thereof to the Master Collateral

         Section 5.04. Waiver of Stay or Extension Laws; Marshalling of Assets.
The Bank and WFAL 2 covenant, to the fullest extent permitted by applicable law,
that they, and each of them, will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any appraisement,
valuation, stay, extension or redemption law wherever enacted, now or at any
time hereafter in force, in order to prevent or hinder the enforcement of this
Agreement or any sale of the Collateral or any part thereof in accordance with
this Agreement or the possession thereof by any purchaser at any sale, pursuant
to and in accordance with Section 6.01 hereof; and the Bank and WFAL 2, to the
fullest extent permitted by applicable law, for themselves and all who may claim
under them, or any of them, hereby waive the benefit of all such laws, and
covenant that they will not hinder, delay or impede the execution of any power
herein granted to the Master Collateral Agent, but will suffer and permit the
execution of every such power as though no such law had been enacted. The Bank
and WFAL 2, for themselves and all who may claim under them, waive, to the
fullest extent permitted by applicable law, all right to have the Collateral
marshalled upon any foreclosure or other disposition thereof.

         Section 5.05. Noninterference, etc.. The Bank and WFAL 2 shall not take
any action, or fail to take any action, if such action or failure to take action
will interfere with the enforcement of any rights under this Agreement, the
Servicing Agreement or the Existing Agreements.

         Section 5.06. Changes. Neither the Bank nor WFAL 2 shall change its
name unless it shall have given Financial Security, the Trustee and the Master
Collateral Agent at least sixty (60) days' prior written notice thereof. The
Bank or WFAL 2, as the case may be, shall give Financial Security, the Trustee
and the Master Collateral Agent at least sixty (60) days' prior written notice
of any relocation of its principal executive office. If the Bank or WFAL 2
relocates (i) its principal executive office or principal place of business from
that set forth in Section 8.05 hereof or (ii) the locations where it keeps or
holds any Collateral or any records relating thereto from that set forth in
Section 8.05 hereof, the Bank or WFAL 2, as the case may be, shall give prior
notice thereof to Financial Security, the Trustee and the Master Collateral
Agent.

                              REMEDIES UPON DEFAULT

         Section 6.01. Rights and Remedies Upon Default.

                  (a) In addition to and not in limitation of the rights
otherwise provided to the Controlling Party pursuant to this Agreement, to the
fullest extent permitted by applicable law, if a Default has occurred and is
continuing, the Controlling Party in its discretion may, or may direct the
Master Collateral Agent to, exercise the following rights, privileges and
remedies:

                        (i) Collection of the Collateral. The Master Collateral
Agent shall have the right to collect all proceeds of the Collateral, to pay all
expenses of such collection, including the reasonable expenses and compensation
of the Master Collateral Agent, its agents and attorneys, and to apply the
remainder of the moneys so received as provided herein.

                        (ii) Sale of Collateral. The Master Collateral Agent may
sell, or cause to be sold, the Collateral or any part thereof or interest
therein, at public auction to the highest bidder for cash or at private sale or
auction with or without demand, advertisement or notice of the date, time or
place of sale or any adjournment thereof, upon such terms as the Controlling
Party may approve, and upon such sale the Master Collateral Agent shall make and
deliver to the purchaser or purchasers an appropriate instrument or instruments
of transfer. The Master Collateral Agent is hereby irrevocably appointed the
true and lawful attorney of the Bank and WFAL 2, and each of them, in its name
and stead, to make all necessary transfers of property thus sold; and for that
purpose it may execute all necessary instruments of transfer, and may substitute
one or more Persons with like power, the Bank and WFAL 2, and each of them,
hereby ratifying and confirming all that its said attorney, or such substitute
or substitutes, shall lawfully do by virtue hereof. Nevertheless, if so
requested by the Master Collateral Agent or any purchaser of the Collateral or
any part thereof, the Bank and WFAL 2, and each of them, shall ratify and
confirm any such sale or transfer by executing and delivering to the Master
Collateral Agent or such purchaser all proper instruments of transfer and
releases as may be designated in any such request. The Master Collateral Agent
may proceed at law or in equity to foreclose the lien of this Agreement against
all or any part of the Collateral and to have the same sold under the judgment
or decree of a court having jurisdiction or as otherwise may be required or
permitted by law. Upon any such sale, whether made under the power of sale
hereby given or by virtue of judicial proceedings, the Controlling Party may bid
for and purchase the Collateral or any part thereof and, upon compliance with
the terms of such sale, may hold, retain, possess or dispose of such property in
its or their own absolute right without accountability. Upon any sale, whether
made under the power of sale hereby given or by virtue of judicial proceedings,
a receipt of the Master Collateral Agent, or of the officer making such sale
under judicial proceedings, shall be a sufficient discharge to the purchaser or
purchasers at such sale for its or their purchase money, and such purchaser or
purchasers shall not be obliged to see to the application thereof. Any such
sale, whether under the power of sale hereby given or by virtue of judicial
proceedings, shall bind the Master Collateral Agent, the Bank and WFAL 2, shall
operate to divest all right, title and interest whatsoever, either at law or in
equity,


                                       21
<PAGE>   25

of each of them in and to the property sold, and shall be a perpetual bar, both
at law and in equity, against each of them and their successors and assigns, and
against any and all Persons claiming through or under them.

                        (iii) Other Actions. The Master Collateral Agent shall
have the right to cause any other action permitted at law or in equity to be
initiated and prosecuted to enforce this Agreement and any rights granted by
virtue of the pledge of the Collateral hereunder.

                  (b) In the event that the Bank or WFAL 2 shall default in the
performance or observance of any covenant or agreement contained herein, the
Master Collateral Agent shall have the right to take any action or initiate any
proceeding at law or equity available to it to enforce the terms of this
Agreement.

         Section 6.02. Restoration of Rights and Remedies. If the Master
Collateral Agent has instituted any proceeding to enforce any right or remedy
under this Agreement, and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to such Master Collateral Agent,
then and in every such case the Bank, WFAL 2 and the Master Collateral Agent
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder, and thereafter all rights
and remedies of the Controlling Party shall continue as though no such
proceeding had been instituted.

         Section 6.03. No Remedy Exclusive. No right or remedy herein conferred
upon or reserved to the Master Collateral Agent or the Controlling Party is
intended to be exclusive of any other right or remedy, and every right or remedy
shall, to the extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter existing at law, in
equity or otherwise, and each and every right, power and remedy whether
specifically herein given or otherwise existing may be exercised from time to
time and as often and in such order as may be deemed expedient by the
Controlling Party, and the exercise of or the beginning of the exercise of any
right or power or remedy shall not be construed to be a waiver of the right to
exercise at the same time or thereafter any other right, power or remedy.


                                  ARTICLE VII

                                    CUSTODY

         Section 7.01. Collateral Schedule; Collateral Files. On each date on

deliver to the Master Collateral Agent, the Trustee and Financial Security a

Collateral, sets forth, to the extent applicable, the obligor's name, the loan
or other identifying number, the interest rate, the original principal balance,

                  On each Pledge Date, the Bank and WFAL 2 shall deliver to the
Master Collateral Agent the following documents with respect to each Mortgage
Loan pledged on such date to the Master Collateral Agent:

                  a.  Original mortgage note endorsed or assigned without
                      recourse to Bankers Trust Company of California, N.A., as
                      Master Collateral Agent;

                  b.  Original recorded mortgage or deed of trust or certified
                      copy thereof; and

                  c.  Original assignment, in recordable form, of mortgage or
                      deed of trust (which may be a blanket assignment for all
                      Mortgage Loans) to Bankers Trust Company of California,
                      N.A., as Master Collateral Agent.

                  The Bank and WFAL 2 jointly and severally represent, warrant
and covenant to the Master Collateral Agent, the Trustee and Financial Security
that, with respect to each Mortgage Loan pledged to the Master Collateral Agent
hereunder, the Bank or WFAL 2 has (i) originals of all assumption and
modification agreements related thereto, (ii) evidence of homeowners insurance
on the related mortgaged property, and (iii) a title insurance policy.

                  Upon receipt by the Bank and WFAL 2 of an FSA Notice stating
that a Default has occurred and is continuing, the Bank and WFAL 2 shall deliver
to the Master Collateral Agent all documents and instruments specified in the
immediately preceding paragraph and such other documents and instruments with
respect to each Mortgage Loan, Contract, Federal Agency Security or other item
of Collateral pledged hereunder to the Master Collateral Agent in which a
security interest may be perfected by possession.

                  The documents and instruments delivered in respect of each
Mortgage Loan, Contract, Federal Agency Security or other item of Collateral are
herein referred to as the "Collateral File". The Master Collateral Agent shall
segregate and maintain continuous custody of all documents constituting each
Collateral File in secure and fireproof facilities within the State of
California in accordance with customary standards for such custody.

         Section 7.02. Release of Documents to Servicer. In the event that a
specific document relating to an item of Collateral is required to be obtained
by the Servicer because such Collateral has been paid in full and is to be
released by the Servicer to the related obligor or to facilitate enforcement and
collection procedures with respect to such Collateral, the Servicer shall be
entitled to obtain such document by submitting to the Master Collateral Agent
(with copies to the Trustee and Financial Security) a written request therefor,
indicating and confirming that it will hold such document in trust for the
benefit of the Master Collateral Agent until such time as it is released to the
related obligor upon full payment or is otherwise returned to the Master
Collateral Agent. Upon its receipt of an FSA Notice stating that a Default has
occurred and is continuing, the Master Collateral Agent shall not release such
document to the Servicer until it has received the written authorization from
the Controlling Party.

         Section 7.03. Insurance. The Master Collateral Agent shall, at its own
expense, maintain at all times during the existence of this Agreement and keep
in full force and effect (a) fidelity insurance, (b) theft of documents
insurance and (c) forgery insurance. All such insurance shall be in amounts,
with standard coverage and subject to deductibles, as are customary for
insurance typically maintained by institutions which act as custodian in similar
transactions.

         Section 7.04. Master Collateral Agent's Interest in Collateral. By
execution of this Agreement, the Master Collateral Agent warrants and covenants
that it currently does not hold, and during the existence of this Agreement will
not hold, any adverse interest, by way of security or otherwise, in any
Collateral and hereby waives and releases any such interest which it may have or
acquire in the future. The Master Collateral Agent expressly waives (i) any lien
which might arise in connection with unpaid fees or any lien which might arise
in connection with any other claims against any party hereto and (ii) any
possessory lien, claim or right of set-off with respect to any Collateral.


                                  ARTICLE VIII

                                  MISCELLANEOUS

         Section 8.01. Further Assurances. Each of the Bank, WFAL 2 and the
Master Collateral Agent shall take such action and deliver such instruments, in
addition to the actions and instruments specifically provided for herein, as may
be reasonably requested or required by the Controlling Party to effectuate the
purpose or provisions of this Agreement or to confirm or perfect any transaction
described or contemplated herein. The parties hereto will make any changes
required by the Office of Thrift Supervision if mutually agreed by the parties
hereto and if there is no such mutual agreement, the Bank, WFAL 2 and the
Controlling Party agree to terminate this Agreement.

         Section 8.02. Waiver. Any waiver by any party of any provision of this
Agreement or any right, remedy or option hereunder shall only prevent and stop
such party from thereafter enforcing such provision, right, remedy or option if
such waiver is given in writing and only as to the specific instance and for the
specific purpose for which such waiver was given. The failure or refusal of any
party hereto to insist in any one or more instances, or in a course of dealing,
upon the strict performance of any of the terms or provisions of this Agreement
by any party hereto or the partial exercise of any right, remedy or option
hereunder shall not be construed as a waiver or relinquishment of any such term
or provision, but the same shall continue in full force and effect.

         Section 8.03. Amendments. This Agreement may be amended, changed,
modified, altered or terminated only by written instrument or written
instruments signed by each of the parties hereto; provided that the consent of
the Master Collateral Agent shall not be withheld or delayed with respect to any
amendment that does not adversely affect the Master Collateral Agent and,
provided further that Schedule A hereto may be amended or replaced as set forth
